ITEM 1. BUSINESS

OVERVIEW

We are a global biotechnology company that invests in scientific innovation to create transformative medicines for people with serious diseases with a

focus on specialty markets.

Cystic Fibrosis

Our goal is to develop treatment regimens that will provide benefits to all people with cystic fibrosis, or CF, and will enhance the benefits currently

provided to people taking our medicines. Our marketed medicines are TRIKAFTA/KAFTRIO (elexacaftor/tezacaftor/ivacaftor and
ivacaftor), SYMDEKO/SYMKEVI (tezacaftor/ivacaftor and ivacaftor), ORKAMBI (lumacaftor/ivacaftor) and KALYDECO (ivacaftor). Our triple
combination regimen, TRIKAFTA/KAFTRIO, was approved in 2019 in the United States, or U.S., and in 2020 in the European Union, or E.U. Collectively,
our four medicines are approved to treat the majority of the approximately 83,000 people with CF in North America, Europe and Australia. We are evaluating
our medicines, including our triple combination regimen, in additional patient populations, including younger children, with the goal of having small molecule
treatments for up to 90% of people with CF. We are pursuing genetic therapies to address the remaining 10% of people with CF.

Research and Development

Our goal is to identify and develop innovative medicines by combining transformative advances in the understanding of human disease and in the science
of therapeutics to advance human health. Our research and early development strategy includes advancing multiple compounds from each program into early
clinical trials and evaluating the resulting data to inform drug discovery and development, with the goal of bringing best-in-class therapies to patients. This
strategy and approach is intended to increase the likelihood of successfully bringing transformative medicines to patients.

Small Molecule Programs

Alpha-1 Antitrypsin Deficiency. We are focused on identifying and developing multiple drug candidates with the potential to increase the levels of

functional alpha-1 antitrypsin, or AAT, in the blood, to address the lung and liver manifestations of AAT deficiency. Enrollment is ongoing in a Phase 2 proof-
of-concept trial for VX-864, an investigational small molecule corrector for the treatment of AAT deficiency. We expect data from this clinical trial in the first
half of 2021.

APOL1-Mediated Kidney Diseases. We are evaluating inhibitors of APOL1 function to reduce levels of protein in the urine, or proteinuria, in people with
serious kidney diseases, including focal segmental glomerulosclerosis, or FSGS, and other APOL1-mediated kidney diseases. In 2020, we initiated a Phase 2
proof-of-concept clinical trial designed to evaluate the reduction in proteinuria in people with APOL1-mediated FSGS after treatment with VX-147.
Enrollment in this clinical trial is ongoing and we expect data in 2021.

Pain. We believe that NaV1.8 inhibitors have the potential to provide an effective non-opioid treatment for pain. We are advancing a portfolio of NaV1.8

inhibitors through pre-clinical and early clinical development.

Cell and Genetic Therapies

Sickle cell disease and transfusion-dependent beta thalassemia. We are co-developing CTX001, an investigational CRISPR/Cas9-based gene-editing
therapy for sickle cell disease, or SCD, and transfusion-dependent beta thalassemia, or TDT, with CRISPR Therapeutics AG, or CRISPR. Enrollment and
dosing are ongoing in two Phase 1/2 clinical trials to evaluate CTX001 as a potential one-time curative therapy for people with severe SCD and TDT. In
December 2020, we announced positive interim data from 10 people treated with CTX001 and that a total of thirteen people with TDT and seven people with
severe SCD have been dosed with CTX001. We expect to complete enrollment in both clinical trials in 2021.

Type 1 Diabetes. In 2019, we acquired Semma Therapeutics, Inc., or Semma, and established preclinical cell therapy programs for type 1 diabetes, or
T1D. We are pursuing two programs for the transplant of functional islets into patients: transplantation of islet cells alone, using immunosuppression to protect
the implanted cells, and implantation of the islet cells inside a novel immunoprotective device. The FDA has cleared our Investigational New Drug
Application, or IND, for

1

VX-880, the first program (transplantation of islet cells alone), and we expect to initiate a Phase 1/2 clinical trial evaluating VX-880 in the first half of 2021.

Duchenne muscular dystrophy, or DMD, and myotonic dystrophy type 1, or DM1. In 2019, we acquired Exonics Therapeutics, Inc., or Exonics, and

expanded our collaboration with CRISPR enabling the establishment of preclinical genetic therapy programs for DMD and DM1.

We plan to continue investing in our research and development programs and fostering scientific innovation by continuing to identify additional drug

candidates through our internal research efforts and investing in business development transactions to access emerging technologies, drugs and drug
candidates.

CYSTIC FIBROSIS

Background

CF is a life-shortening genetic disease caused by a defective or missing CFTR protein resulting from mutations in the CFTR gene. To develop CF,

children must inherit two defective CFTR genes, which are referred to as alleles; one allele is inherited from each parent. The vast majority of patients with CF
carry at least one of the two most prevalent mutations, the F508del mutation and the G551D mutation. The F508del mutation results in a defect in the CFTR
protein in which the CFTR protein does not reach the surface of the cells in sufficient quantities and does not adequately transport chloride ions. The G551D
mutation results in a defect in the CFTR protein in which the defective protein reaches the surface of a cell but does not adequately transport chloride ions
across the cell membrane.

The absence of working CFTR proteins results in poor flow of salt and water into and out of cells in a number of organs, including the lungs. As a result,
thick, sticky mucus builds up and blocks the passages in many organs, leading to a variety of symptoms. In particular, mucus builds up and clogs the airways
in the lungs, causing chronic lung infections and progressive lung damage. CFTR potentiators such as ivacaftor and VX-561 increase the probability that the
CFTR protein channels open on the cell surface, increasing the flow of salt and water into and out of the cell. Our CFTR correctors, such as lumacaftor,
tezacaftor, and elexacaftor, help CFTR proteins reach the cell surface.

In addition to the E.U. and the U.S., we market our products in additional countries, including the United Kingdom, Australia, Switzerland, Israel, and

Canada. Currently, our medicines treat almost half of the people with CF in these geographies. We continuously seek to increase the number of patients
eligible and able to receive our current medicines through label expansions, approval of new medicines and expanded reimbursement. Since the beginning of
2020, activities in support of these efforts include:

TRIKAFTA/KAFTRIO

•

•

•

In August, the European Commission granted marketing authorization for KAFTRIO to treat people with CF 12 years of age and older with one
F508del mutation and one minimal function mutation, or two F508del mutations.

The FDA expanded the eligibility for TRIKAFTA to include people with CF 12 years of age and older with certain mutations that are responsive to
TRIKAFTA based on in vitro data.

In January 2021, the FDA accepted our supplemental New Drug Application, or sNDA, for TRIKAFTA for the treatment of children 6 to 11 years of
age with at least one F508del mutation or have certain mutations that are responsive to TRIKAFTA based on in vitro data. The FDA granted Priority
Review of the sNDA.

3

•

Swissmedic, the Swiss Agency for Therapeutic Products, granted marketing authorization and a reimbursement agreement was reached for
TRIKAFTA in Switzerland for the treatment of people with CF 12 years of age and older who have two copies of the F508del mutation, or one
F508del mutation and one minimal function mutation.

• Health Canada accepted for Priority Review a New Drug Submission for TRIKAFTA for the treatment of people with CF 12 years of age and older.

SYMDEKO/SYMKEVI

•

•

The European Commission approved SYMKEVI for the treatment of people with CF 6 years of age and older with two copies of the F508del
mutation, or one F508del mutation and certain residual function mutations.

The FDA approved SYMDEKO for additional responsive mutations in people with CF 6 years of age and older.

ORKAMBI

• We entered into a reimbursement agreement with the Swiss government for ORKAMBI for the treatment of people with CF 2 years of age and older,

and for SYMDEKO for the treatment of people 12 years of age and older in Switzerland.

KALYDECO

•

•

•

The FDA approved KALYDECO for treatment of infants with CF four months of age and older who have at least one mutation in their CFTR gene
that is responsive to KALYDECO.

The European Commission approved KALYDECO for treatment of infants with CF four months of age and older who have the R117H mutation or
certain gating mutations.

The FDA approved KALYDECO for treatment of infants with CF four months of age and older with additional responsive mutations.

CF PIPELINE

• VX-561, a CFTR potentiator we acquired from Concert Pharmaceuticals, Inc., and VX-121, a CFTR corrector, are being evaluated in Phase 2 clinical

development.

• We continue to identify and develop additional CFTR modulators with the goal of achieving carrier levels of CFTR activity for the 90% of people

with CF who respond to CFTR modulators.

• We continue to research genetic therapies, such as messenger ribonucleic acid, or mRNA, and gene-editing approaches, to treat the remaining 10% of

people who do not make CFTR protein and, as a result, are not eligible for CFTR modulators.

• We extended our collaboration with Moderna, Inc., or Moderna, aimed at the discovery and development of mRNA therapeutics for the treatment of
CF. In addition, we entered into a new collaboration with Moderna for the discovery and development of lipid nanoparticles and mRNAs that can
deliver gene-editing therapies to lung cells for the treatment of CF.

RESEARCH AND DEVELOPMENT PROGRAMS

We invest in research and development in order to discover and develop transformative medicines for people with serious diseases with a focus on
specialty markets. Our strategy is to combine transformative advances in the understanding of human disease and the science of therapeutics in order to
discover and develop new medicines. Our approach to drug discovery has been validated through our success in moving novel small molecule drug candidates
into clinical trials and obtaining marketing approvals for TRIKAFTA/KAFTRIO, KALYDECO, ORKAMBI and SYMDEKO/SYMKEVI for the treatment of
CF and INCIVEK (telaprevir) for the treatment of hepatitis C infection. In addition, we have achieved clinical proof of concept for Nav1.8 inhibition in the
treatment of three different pain models, and for gene-editing of BCL11A for the treatment of beta thalassemia and SCD.

4

We continue to research and develop small molecule drug candidates for the treatment of serious diseases, including CF, AAT deficiency, APOL1-
mediated kidney diseases, and pain. Our research and development approach includes advancing multiple small molecules into clinical trials, pursuing
multiple modalities and evaluating clinical and non-clinical data to inform drug discovery and development, with the goal of bringing best-in-class therapies to
patients.

Over the last several years, we have expanded our capabilities to include additional innovative therapeutic approaches with a focus on cell and

genetic therapies, which have the potential to treat, and in some cases, cure diseases by addressing the underlying cause of the disease. We have expanded our
capabilities by increasing our internal investment in cell and genetic therapies, including plans to establish a new research and development site in Boston that
will focus primarily on cell and genetic therapies. In addition, we have made several significant investments in external innovation, including:

•

•

•

•

•

our collaboration with CRISPR to access and develop therapeutics based on the CRISPR gene-editing technology;

our establishment of cell therapy programs for T1D through our acquisition of Semma;

our establishment of genetic therapy programs for DMD and DM1, through our acquisition of Exonics;

our collaboration with Moderna for the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies; and

our collaboration with Affinia Therapeutics, Inc., or Affinia, to engineer novel adeno-associated virus (AAV) capsids to deliver gene therapies.

The experience we gained developing medicines for CF and our analysis of research and development programs conducted by other companies in our

industry have shaped a disciplined strategy that guides our investments in research and development and external innovation that focuses on:

•    transformative treatments for life-threatening diseases with a high unmet medical need;

•    targets validated as playing a causal role in the human biology of a disease;

•

•

innovative therapeutic approaches to addressing those targets;

biological assays and clinical biomarkers that we believe will be predictive of clinical responses; and

•    efficient clinical and regulatory paths to bring new medicines to patients.

To augment our internal programs, we plan to continue acquiring businesses and technologies and collaborating with biopharmaceutical and technology

companies, leading academic research institutions, government laboratories, foundations and other organizations to advance research in our areas of
therapeutic interest as well as to access technologies needed to execute on our strategy. We have established such relationships with organizations around the
world and intend to extend and leverage that experience to further our research efforts to discover transformational medicines for serious diseases. We will
continue to identify and evaluate potential acquisitions and collaborations that may be similar to or different from the transactions that we have engaged in
previously.

Small Molecule Programs

Alpha-1 Antitrypsin Deficiency

AAT deficiency is caused by mutations in the SERPINA1 gene that encodes the AAT protein. People who inherit two mutant SERPINA1 alleles (one
from each parent) develop AAT deficiency. Most people who develop AAT deficiency have two copies of the mutant Z allele. The mutations result in a defect
in the AAT protein in which the protein does not fold correctly. This folding defect causes the AAT protein to accumulate in the liver (where it is produced at
high levels), which can cause liver damage. As a result, the protein fails to reach other organs in adequate quantity and function, particularly in the lungs,
where its normal role is to protect them from the digestive effects of certain proteases. The unchecked activity of these proteases can cause auto-digestion of
lung tissue and may lead to emphysema or chronic pulmonary obstructive disease, and lung infections over time. Currently, there is no cure or treatment that
targets the underlying cause of the disease in both the liver and the lung. Available treatments are aimed at transiently increasing levels of AAT in the blood
but have no effect

5

in the liver. Patients living with AAT deficiency typically experience recurring hospital visits and a shortened life expectancy.

We seek to develop medicines that treat the underlying cause of AAT deficiency. In the laboratory, we have discovered multiple small molecule correctors

that restore folding of the mutant AAT protein, with the potential to affect both the liver and lung diseases caused by AAT deficiency, and we are focused on
identifying and developing multiple drug candidates with the potential to correct the misfolded protein. In 2020, we advanced two Phase 2 proof-of-concept
clinical trials evaluating two investigational oral small molecule correctors, VX-814 and VX-864, for the treatment of people with AAT deficiency who have
two copies of the Z mutation. In October 2020, we discontinued development of VX-814 based on the safety and pharmacokinetic profile observed in the
clinical trial. Enrollment is ongoing in the clinical trial evaluating VX-864, and we expect data from this clinical trial in the first half of 2021. In addition, we
continue to discover and develop additional molecules with the potential to correct AAT deficiency.

APOL1-Mediated Kidney Diseases

Inherited mutations in the APOL1 gene play a causal role in the biology of FSGS as well as other kidney diseases. FSGS is a rare disease that attacks the

kidney’s filtering units, causing leakage of protein into the urine followed by deterioration in kidney function, scarring, and, ultimately, permanent kidney
damage. FSGS is a leading cause of nephrotic syndrome in children and kidney failure in adults. We are evaluating multiple novel small molecules that inhibit
the function of APOL1 protein with the potential to treat APOL1-mediated FSGS. In 2020, we initiated a Phase 2 proof-of-concept clinical trial for VX-147,
our first investigational oral small molecule medicine for the treatment of FSGS and other serious kidney diseases. Enrollment is ongoing in this Phase 2
clinical trial and we expect data from the trial in 2021.

Pain

Pain can develop from a variety of pathophysiological and psychological conditions. Patients with pain can suffer from acute pain (for example, following

surgery or an injury), neuropathic pain (when there is damage to a nerve), and musculoskeletal pain. Current treatments may not work well and can cause
significant side effects. In addition, there is the potential for addiction and the practice of over- and mis-utilization, as well as underutilization of current pain
medicines.

Vertex has discovered multiple inhibitors of the voltage-gated sodium channel 1.8, or NaV1.8, as potential treatments for pain. Consistent with our
research strategy, the Nav1.8 channel is a validated target for pain based both on inherited mutations that cause pain syndromes as well as our own clinical
trial data. Specifically, we have obtained positive results from three separate Phase 2 clinical trials evaluating VX-150, a NaV1.8 inhibitor, in patients with
three different pain conditions: acute post-surgical, chronic neuropathic and chronic musculoskeletal pain. We continue to focus our research and development
efforts on discovering, developing and advancing a portfolio of multiple inhibitors of NaV1.8 as potential treatments for pain.

Cell and Genetic Therapies

Sickle Cell Disease and Beta Thalassemia

SCD and beta thalassemia are hemoglobinopathies, a group of inherited blood disorders that result from gene mutations that alter hemoglobin, a protein in

red blood cells that delivers oxygen throughout the body.

SCD is caused by the change of a single amino acid in the hemoglobin gene that causes red cells to change shape in settings of low oxygen. These sickled

cells block blood flow and can lead to severe pain, organ damage and shortened life span. Treatment is typically focused on relieving pain and minimizing
organ damage, requiring medication and, for some patients, monthly blood transfusions and frequent hospital visits. We believe there are approximately
25,000 patients with severe SCD in the U.S. and E.U.

Beta thalassemia is caused by loss-of-function mutations in hemoglobin that lead to severe anemia in patients, which causes fatigue and shortness of
breath. In infants, beta thalassemia causes failure to thrive, jaundice and feeding problems. Complications of beta thalassemia can lead to an enlarged spleen,
liver and/or heart, misshapen bones and delayed puberty. Treatment for beta thalassemia varies depending on the disease severity for each patient. Patients
with TDT, the most severe form of the disease, require regular blood transfusions, as frequently as every two to four weeks. Repeated blood transfusions
eventually cause an unhealthy buildup of iron in the patient, leading to organ damage. We believe that there are approximately 7,000 patients with TDT in the
U.S. and E.U.

6

In collaboration with CRISPR, we are co-developing CTX001, an investigational CRISPR/Cas9-based gene-editing therapy, for the treatment SCD and

TDT. Our therapeutic approach involves isolating hematopoietic stem and progenitor cells, or HSPCs, which give rise to red blood cells, from a patient,
treating those cells ex vivo with CRISPR/Cas9 in order to modify the erythroid-specific enhancer in the BCL11A gene, and reintroducing the edited cells back
into the patient. This approach has the potential to increase levels of fetal hemoglobin in erythrocytes and reduce or eliminate symptoms associated with
disease.

We and CRISPR are investigating CTX001 in two Phase 1/2 open-label clinical trials designed to assess the safety and efficacy of a single dose of
CTX001 in patients ages 12 to 35 with TDT (CLIMB THAL-111) and severe SCD (CLIMB SCD-121), respectively. Patients enrolled in the clinical trial first
undergo a treatment which mobilizes a population of HSPCs from the bone marrow into the bloodstream. Blood cells are collected from the patient’s
bloodstream and sent to a manufacturing facility where the HSPCs are purified and CRISPR/Cas9 gene-editing is performed. Following manufacturing, the
edited cells, now called CTX001, are sent back to the clinical site. Patients are preconditioned with a treatment that ablates their bone marrow prior to infusion
of CTX001.

In December 2020, we announced positive interim data from 10 people treated with CTX001 and that 20 people with severe hemoglobinopathies have

been dosed with CTX001 in the ongoing Phase 1/2 clinical trials. All seven people with TDT were transfusion independent at last follow-up and all three
people with SCD were free of vaso-occlusive crises from CTX001 infusion through the last follow-up. Enrollment and dosing are ongoing, and completion of
enrollment for both clinical trials is expected in 2021.

Type 1 Diabetes

T1D is a chronic, metabolic disorder caused by an absence of insulin secretion by the beta cells in the pancreas. In patients with T1D, the person’s own
immune system attacks the insulin-producing islet cells of the pancreas, resulting in a complete lack of insulin. While insulin therapy allows patients to live
for decades with the disease, challenges of insulin therapy include inadequate control of blood sugar (both hyper- and hypo-glycemia), burden of care on
patients and families, and long-term vascular complications.

In 2019, we acquired Semma and established programs to develop cell-based therapies designed to replace insulin-producing islet cells in people with
T1D. We are pursuing two programs for the transplant of functional islets into patients: transplantation of islet cells alone, using immunosuppression to protect
the implanted cells, and implantation of the islet cells inside an immunoprotective device. The FDA has cleared our IND for VX-880, the first program
(transplantation of islet cells alone), and we expect to initiate a Phase 1/2 clinical trial evaluating VX-880 in the first half of 2021. This clinical trial will
involve an infusion of fully differentiated, functional islet cells, and chronic administration of concomitant immunosuppressive therapy, to protect the islet
cells from immune rejection.

Duchenne Muscular Dystrophy

DMD and DM1 are inherited diseases that result in the weakening and breakdown of skeletal muscles over time. In 2019, we acquired Exonics and

expanded our collaboration with CRISPR establishing preclinical programs to develop gene-editing therapies for DMD and DM1. We are focused on
advancing gene-editing therapies aimed at treating the underlying cause of DMD by restoring expression of near-full length dystrophin protein, and in DM1
by addressing the repeat expansion that causes the disease. Our collaboration with Affinia enables access to a novel library of AAV capsids to support our
ongoing research and development efforts in genetic therapies, including DMD and DM1.

COMMERCIALIZATION OF OUR MEDICINES

Commercial Organization

Our commercial organization focuses on supporting sales of TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, ORKAMBI and KALYDECO in the
markets where these products have been approved. Our sales and marketing organizations are responsible for promoting products to health care providers and
obtaining reimbursement for our products from third-party payors, including governmental organizations in the U.S. and ex-U.S. markets.

Our U.S. field-based CF commercial team is comprised of a small number of individuals to support commercialization of our medicines for CF. We focus

our CF marketing efforts in the U.S. on a relatively small number of physicians and health

7

care professionals who write most of the prescriptions for CF medicines. Many of these physicians and health care professionals are located at a limited
number of accredited centers in the U.S. focused on the treatment of CF. In international markets, we have small sales forces that support KALYDECO,
ORKAMBI, SYMDEKO/SYMKEVI and TRIKAFTA/KAFTRIO in jurisdictions where these products are approved.

We market our products through personal interactions with physicians and allied health care professionals. In addition, our government affairs and public

policy group advocates for policies that promote life sciences innovation and increase awareness of the diseases on which we are focusing with state and
federal legislatures, government agencies, public health officials and other policymakers. We also have established programs in the U.S. that provide our
products to qualified uninsured or underinsured patients at no charge or at a reduced charge, based on specific eligibility criteria.

Reimbursement

Sales of our products depend, to a large degree, on the extent to which our products will be reimbursed by third-party payors, such as government health

programs, commercial insurance and managed health care organizations. Increasingly, these third-party payors are becoming stricter in the ways they evaluate
medical products and services. Additionally, the containment of health care costs has become a priority of federal and state governments, and the prices of
drugs have been a focus in this effort. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-
containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption of price
controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could limit our
revenues. Decisions by third-party payors to not cover a product could reduce physician usage of the product.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, established the Medicare Part D program to provide a
voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private
entities, which provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. Part D prescription drug
plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will
cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D
drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed
by a pharmacy and therapeutics committee. Government payment for some of the costs of prescription drugs may increase demand for products for which we
receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan likely will be lower than the prices we
might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage
policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in
payments from non-governmental payors.

The American Recovery and Reinvestment Act of 2009 provided funding for the federal government to compare the effectiveness of different treatments

for the same illness. A plan for the research was to be developed by the Department of Health and Human Services, or HHS, the Agency for Healthcare
Research and Quality and the National Institutes of Health, and periodic reports on the status of the research and related expenditures were to be made to the
U.S. Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, it is
not clear what effect, if any, the research will have on the sales of our products. In the future, it is possible that comparative effectiveness research
demonstrating benefits of a competitor’s product could adversely affect the sales of our products. If third-party payors do not consider our products to be cost-
effective compared to other available therapies, they may not cover our products as a benefit under their plans or, if they do, the level of payment may not be
sufficient to allow us to sell our products on a profitable basis.

The Patient Protection and Affordable Care Act, or ACA, was enacted in March 2010 and was designed to expand coverage for the uninsured while at the

same time containing overall health care costs. With regard to pharmaceutical products, among other things, the ACA was designed to expand and increase
industry rebates for drugs covered under Medicaid programs, impose an annual fee on branded pharmaceutical manufacturers and make changes to the
coverage requirements under the Medicare Part D program.

In Europe and other foreign jurisdictions, the success of our products depends largely on obtaining and maintaining government reimbursement because

many patients are unable to access prescription pharmaceutical products that are not

8

reimbursed by their governments. Negotiating reimbursement agreements in foreign countries can delay the commercialization of a pharmaceutical product
and can result in a reimbursement price that is lower than the net price that companies can obtain for the product in the U.S.

In some countries, such as Germany, commercial sales of a new product may begin while the reimbursement rate that a company will receive is under
discussion. In other countries, a company must complete reimbursement negotiations prior to the commencement of commercial supply of the pharmaceutical
product. The requirements governing drug pricing vary widely from country to country. For example, the member states of the E.U. can restrict the range of
drugs for which their national health insurance systems provide reimbursement and can control the prices of prescription drugs. In addition, many ex-U.S.
government payers require companies to provide health economic assessments of products, which are evaluated by government agencies set up for this
purpose. A member state may approve a specific price for the drug or it may instead adopt a system of direct or indirect controls on the total amount of money
that a company may receive for supply of a drug. Countries also may consider increasing mandatory discounts in an attempt to manage increased demands on
healthcare budgets. Reimbursement for our products cannot be assured. In addition, it is possible that a country may only provide for reimbursement on terms
that we do not deem adequate. Additionally, reimbursement discussions in ex-U.S. markets may take a significant period of time.

STRATEGIC TRANSACTIONS AND COLLABORATIONS

As part of our business strategy, we seek to license or acquire drugs, drug candidates, businesses and other technologies that have the potential to
complement our ongoing research and development efforts. In addition, we establish business relationships with collaborators to support our research
activities and to lead or support development and/or commercialization of certain drug candidates. We expect to continue to identify and evaluate potential
acquisitions, licenses and collaborations that may be similar or different from the transactions that we have engaged in previously.

Strategic Transactions

Acquisitions

In 2019, we acquired Semma, a privately-held company focused on the use of stem cell-derived human islets as a potentially curative treatment for T1D.

Our acquisition of Semma advanced our cell therapy capabilities and supports the development of transformative therapies for T1D. In connection with the
acquisition, we acquired all of the outstanding equity of Semma for approximately $950.0 million in cash.

In 2019, we acquired Exonics, a privately held company focused on creating transformative gene-editing therapies to repair mutations that cause DMD

and other severe neuromuscular diseases, including DM1. Our acquisition of Exonics enhanced our gene-editing capabilities and supports the potential
development of novel therapies for DMD and DM1. In connection with the acquisition, we acquired all of the outstanding equity of Exonics for an upfront
payment of approximately $245.0 million plus customary working capital adjustments in cash, and certain potential future payments based primarily upon the
successful achievement of specified development and regulatory milestones for the DMD and DM1 programs.

Collaboration and Licensing Arrangements

Joint Development and Commercialization Agreement with CRISPR

In December 2017, we entered into a joint development and commercialization agreement, or JDA, with CRISPR pursuant to which we are co-developing

and preparing to co-commercialize CTX001 for TDT and SCD. This JDA was entered into following our exercise of an option to co-develop and co-
commercialize the hemoglobinopathies program that was contained in the collaboration agreement that we entered into with CRISPR in 2015. The net profits
and net losses, as applicable, incurred under the JDA will be shared equally by the parties. Under the JDA, CRISPR will be responsible for commercialization
activities in the U.S. and we will be responsible for commercialization activities outside of the U.S. There is a joint committee to provide high-level oversight
and decision-making regarding the activities covered by the JDA. The committee contains an equal number of representatives from us and CRISPR.

Either party can terminate the JDA upon the other party’s material breach, subject to specified notice and cure provisions, or, in our case, in the event that

CRISPR becomes subject to specified bankruptcy, winding up or similar

9

circumstances. Either party may terminate the JDA in the event the other party commences or participates in any action or proceeding challenging the validity
or enforceability of any patent that is licensed to such challenging party pursuant to the JDA. We also have the right to terminate the JDA for convenience at
any time after giving prior written notice. If circumstances arise pursuant to which a party would have the right to terminate the JDA on account of an uncured
material breach, such party may elect to keep the JDA in effect and cause such breaching party to be treated as if it had exercised its opt-out rights with respect
to the products associated with such uncured material breach and the royalties payable to the breaching party would be reduced by a specified percentage.

Either party may opt of out of the development of a product candidate under the JDA after predetermined points in the development of the product
candidate, on a candidate-by-candidate basis. In the event of such opt-out, the party opting-out will no longer share in the net profits and net losses associated
with such product candidate and, instead, the opting out party will be entitled to high single to mid- teen percentage royalties on the net sales of such product,
if commercialized.

In-License Agreements

We have entered into various agreements pursuant to which we have obtained access to technologies from third parties and are conducting research and

development activities with collaborators. Pursuant to these arrangements, we have obtained development and commercialization rights to resulting drug
candidates. Depending on the terms of the arrangements, we may be responsible for the costs of research activities, required to make upfront payments and/or
milestone payments upon the achievement of certain research and development objectives, and/or pay royalties on future sales, if any, of commercial products
resulting from the collaboration. Our current in-license agreements include:

• Affinia Therapeutics, Inc. In 2020, we entered into a collaboration with Affinia to gain access to a novel library of AAV capsids to support on our

ongoing research and development efforts in genetic therapies, including DMD, DM1 and CF.

• Arbor Biotechnologies, Inc. In 2018, we entered into a collaboration with Arbor Biotechnologies, pursuant to which we are focusing on the discovery

of novel proteins, including DNA endonucleases, to advance the development of new gene-editing therapies.

•

CRISPR Therapeutics AG. In 2015, we entered into a collaboration with CRISPR for the discovery and development of potential new treatments
aimed at the underlying genetic causes of human diseases using CRISPR-Cas9 gene-editing technology. As described above, we currently are co-
developing CTX001 for the treatment of SCD and beta thalassemia and, if successful, have agreed to co-commercialize CTX001. In addition, we
have exercised options to exclusively license treatments for specific targets, including CF, that were subject to the research program. In 2019, we
obtained exclusive worldwide rights to CRISPR’s intellectual property for DMD and DM1 gene-editing products through a new agreement with
CRISPR.

• Kymera Therapeutics, Inc. In 2019, we entered into a collaboration with Kymera Therapeutics for the research and development of small molecule
protein degraders. Under the collaboration, Kymera Therapeutics conducts research activities in multiple targets, and upon designation of a clinical
development candidate for a target, we have the option to exclusively license molecules against the target.

• Moderna, Inc. In 2016, we entered into a collaboration with Moderna, pursuant to which we are seeking to identify and develop mRNA therapeutics
for the treatment of CF. In 2020, we entered into a new strategic collaboration with Moderna aimed at the discovery and development of lipid
nanoparticles and mRNAs that can deliver gene-editing therapies to lung cells for the treatment of CF.

•

Skyhawk Therapeutics, Inc. In December 2020, we entered into a collaboration with Skyhawk Therapeutics, for the discovery and development of
novel small molecules that modulate RNA splicing for the treatment of serious diseases.

• Other Arrangements. In 2019, we entered into collaborations with Molecular Templates, Inc. and Ribometrix, Inc. In 2018, we entered into

agreements with Genomics plc, Merck KGaA, Darmstadt, Germany, and X-Chem, Inc. in order to support our research and development efforts.

10

Out-license Agreements

We have entered into various agreements pursuant to which we have out-licensed rights to certain drug candidates to third-party collaborators. Pursuant to

these out-license arrangements, our collaborators are responsible for all costs related to the continued development of such drug candidates and obtain
development and commercialization rights to these drug candidates. Depending on the terms of the arrangements, our collaborators may be required to make
upfront payments, milestone payments upon the achievement of certain research and development objectives and/or pay royalties on future sales, if any, of
commercial products licensed under the agreement. Our current out-license agreements include a Strategic Collaboration and License Agreement with Merck
KGaA, Darmstadt, Germany, that we entered into in 2017, pursuant to which we granted an exclusive worldwide license to research, develop and
commercialize four oncology research and development programs.

Cystic Fibrosis Foundation Therapeutics Incorporated

In 2004, we entered into a collaboration agreement with the Cystic Fibrosis Foundation, or CFF, as successor in interest to the Cystic Fibrosis Foundation
Therapeutics, Inc., to support research and development activities. Pursuant to the collaboration agreement, as amended, we have agreed to pay tiered royalties
ranging from single digits to sub-teens on covered compounds first synthesized and/or tested during a research term on or before February 28, 2014, including
KALYDECO (ivacaftor), ORKAMBI (lumacaftor in combination with ivacaftor) and SYMDEKO/SYMKEVI (tezacaftor in combination with ivacaftor) and
royalties ranging from low-single digits to mid-single digits on potential net sales of certain compounds first synthesized and/or tested between March 1, 2014
and August 31, 2016, including elexacaftor. For combination products, such as ORKAMBI, SYMDEKO/SYMKEVI and TRIKAFTA/KAFTRIO (elexacaftor,
tezacaftor, and ivacaftor), sales are allocated equally to each of the active pharmaceutical ingredients in the combination product.

INTELLECTUAL PROPERTY

Patents and other proprietary rights such as trademarks, trade secrets, and copyrights are critical to our business. We actively seek protection for our
products and proprietary information by means of U.S. and foreign patents, trademarks and copyrights, as appropriate. In addition, we rely upon trade secret
protection and contractual arrangements to protect certain of our proprietary information and products.

Patents provide a period of exclusivity that can make it more difficult for competitors to market and use our technology. We own patents and pending

patent applications that relate to compounds, formulations, treatment of diseases, synthetic routes, intermediates and other inventions.

To protect our intellectual property, we typically apply for patents several years before a product receives marketing approval. Under current law, a patent

expires 20 years from its first effective filing date. Since the drug development process may last for many years, there may be a period of time in which we
have an issued patent but not marketing approval to sell the drug. To compensate for patent term lost while a product is in clinical trials and undergoing review
for marketing approval, we may be able to apply for patent term extensions or supplementary protection certificates in some countries. In addition to patent
protection, we have regulatory exclusivity from U.S. and European regulatory agencies for the active pharmaceutical agents and, where applicable, their
approved orphan indications for a certain time period. Regulatory exclusivity runs concurrently with patent exclusivity and provides complementary
protection.

We own or hold exclusive licenses to several hundred patents in the U.S. Upon approval of an NDA or a supplement thereto, NDA sponsors are required

to list with the FDA each patent with claims that cover the applicant’s product or a method of using the product. Each of the patents listed by the NDA sponsor
is published in the FDA’s Orange Book. We have ten issued U.S. patents listed in the Orange Book that cover the active pharmaceutical ingredients in
KALYDECO, its marketed formulations, and/or its approved indication. We have 19 issued U.S. patents listed in the Orange Book that cover the active
pharmaceutical ingredients in ORKAMBI, its marketed formulations, and/or its approved indication. We have 21 issued U.S. patents listed in the Orange
Book that cover the active pharmaceutical ingredients in SYMDEKO, its marketed formulation, and/or its approved indication. We have 21 issued U.S.
patents listed in the Orange Book that cover the active pharmaceutical ingredients in TRIKAFTA, its marketed formulation, and/or its approved indication.

The table below sets forth the year of projected expiration for the basic product patents covering each of our approved products. For products that are

combinations of two or more active ingredients, the table lists the projected expiration of the

11

latest expiring patent covering any of the active pharmaceutical ingredients (lumacaftor for ORKAMBI, tezacaftor for SYMDEKO/SYMKEVI and
elexacaftor for TRIKAFTA/KAFTRIO). Patent term extensions, supplementary protection certificates, and pediatric exclusivity periods are not reflected in the
expiration dates listed in the table below and may extend protection. In some instances, we also own later-expiring patents and applications relating to solid
forms, formulations, methods of manufacture, or the use of these drugs in the treatment of particular diseases or conditions. In some cases, however, such
patents may not protect our drug from generic competition after the expiration of the basic patent.

In addition to protecting our marketed products, we actively monitor and file patent applications in the U.S. and in foreign countries on inventions relating

to our pipeline. For example, we also own U.S. and foreign patents and/or we have patent applications relating to the following:

•

CTX001 and other potential gene-editing approaches for treating hemoglobinopathies.

• VX-864 and other compounds being studied for the potential treatment of AAT deficiency.

• VX-147 and other compounds being studied for the potential treatment of APOL1-mediated kidney diseases.

•

CF potentiators and correctors and many other related compounds, and the use of those compounds to treat CF.

• Other pre-clinical and clinical candidates and the use of such candidates to treat specified diseases.

•

The manufacture, pharmaceutical compositions, related solid forms, formulations, dosing regimens and methods of use of many of the above
compounds.

We and CRISPR intend to rely upon a combination of rights, including patent rights, trade secret protection, and regulatory exclusivities to protect CTX001.
CRISPR has licensed certain rights to a worldwide patent portfolio that covers various aspects of the CRISPR/Cas9 editing platform technology including, for
example, compositions of matter and methods of use, including their use in targeting or cutting DNA from Dr. Charpentier. In addition to Dr. Charpentier, this
patent portfolio has named inventors who assigned their rights to the Regents of the University of California or the University of Vienna, to whom we refer,
together with Dr. Charpentier, as the CVC Group. CRISPR has non-exclusive or co-exclusive rights to the patent rights that protect the core CRISPR/Cas9
gene-editing technology. For example, certain third parties, including competitors, have reported obtaining a license to rights in this patent portfolio in certain
fields. In addition, patents and patent applications in this patent portfolio are the subject of proceedings in the U.S., Europe, and other jurisdictions, including
proceedings between the CVC and the Broad Institute in the U.S. Patent and Trademark Office, or USPTO. To date, both the CVC and the Broad have
obtained granted patents that purport to cover aspects of CRISPR/Cas9 editing platform technology. The patents and patent applications within the CVC
patent portfolio and the Broad patent portfolio are, or may in the future be, involved in proceedings similar to interferences or priority disputes in Europe or
other foreign jurisdictions. In addition to the patent portfolio licensed from Dr. Charpentier, we own patent applications relating to the composition,
manufacture, and use of CTX001.

From time to time we enter into exclusive and non-exclusive license agreements for proprietary third-party technology used in connection with our
research activities. These license agreements typically provide for the payment by us of a license fee but may also include terms providing for milestone
payments or royalties for the development and/or commercialization of our drug products arising from the related research.

We cannot be certain that issued patents we own or license will be enforceable or provide adequate protection or that pending patent applications will

result in issued patents. The existence of patents does not guarantee our right to practice the patented technology or commercialize the patented product.
Litigation, interferences, oppositions, inter partes reviews,

12

administrative challenges or other similar types of proceedings may be necessary in some instances to determine the validity and scope of certain patents,
regulatory exclusivities or other proprietary rights, and in other instances to determine the validity, scope or non-infringement of intellectual property rights
that may be claimed by third parties to be pertinent to the manufacture, use or sale of our products.

MANUFACTURING

As we market and sell our approved products and advance our drug candidates through clinical development toward commercialization, we continue to

build and maintain our supply chain and quality assurance resources. We rely on internal capabilities and a global network of third parties to manufacture and
distribute our products for commercial sale and post-approval clinical trials and to manufacture and distribute our drug candidates for clinical trials. In
addition to establishing supply chains for each new approved product, we need to adapt our supply chain for existing products to include additional
formulations that are often required in order to treat younger patients or to increase scale of production for existing products. We are focused on ensuring the
stability of the supply chains for our current products, including TRIKAFTA/KAFTRIO, and for our pipeline programs. In addition, we are focused on
identifying and ensuring the optimal manufacturing and delivery requirements for the cell and genetic therapies we are developing.

We expect that we will continue to rely on third parties to meet our commercial supply needs and a significant portion of our clinical supply needs for the

foreseeable future. We have established our own small-scale manufacturing capabilities in Boston, which we use for clinical trial and commercial supplies,
and are evaluating additional manufacturing capacity for our current and future products. 

Our supply chain for sourcing raw materials and manufacturing drug product ready for distribution is a multi-step global endeavor. In general, these raw

materials are available from multiple sources. Third-party contract manufacturers, including some in China, perform different parts of our manufacturing
process. Contract manufacturers may supply us with raw materials, convert these raw materials into drug substance and/or convert the drug substance into
final dosage form. In addition, third parties assist us with packaging, warehousing and distribution of products.

Establishing and managing this global supply chain for each of our drugs and drug candidates requires a significant financial commitment and the creation
and maintenance of numerous third-party contractual relationships. To ensure the stability of our supply chains, we aim to develop alternatives for each step of
our manufacturing process at the time of, or shortly after, marketing approval. Therefore, at any point in time, we may have a limited number of single source
manufacturers for certain steps in our manufacturing processes, particularly for recently launched products.

In order to manufacture our commercial products, we utilize both continuous manufacturing technology as well as batch manufacturing processes. While
continuous process manufacturing has been used in many industries, we believe that we are the first company to obtain FDA approval for a fully-continuous
drug product manufacturing process.

We have developed systems and processes to track, monitor and oversee our third-party manufacturers’ activities, including a quality assurance program
intended to ensure that our third-party manufacturers comply with current Good Manufacturing Practices, or cGMP. We regularly evaluate the performance of
our third-party manufacturers with the objective of confirming their continuing capabilities to meet our needs efficiently and economically. Manufacturing
facilities, both foreign and domestic, are subject to inspections by or under the authority of the FDA and other U.S. and foreign government authorities.

The manufacturing processes for cell and genetic therapies are more complex than those required for small molecule drugs and require different systems,
equipment, facilities and expertise. Additionally, we are unable to rely on a single process for all of our cell and genetic therapies; they must be customized for
each program and therapy. Although we have been building expertise in these areas, which was augmented through our acquisitions of Exonics and Semma,
we will need to continue to expand and strengthen our manufacturing infrastructure and capabilities, independently and/or through a third-party network, to
successfully develop and commercialize cell and genetic therapies. We are focused on evaluating and securing potential relationships with various third parties
that would enable us to expand and strengthen such capabilities to support our current and future cell and genetic therapy programs. We expect to make
significant investment in our manufacturing capabilities and partnerships for our genetic and cell-based therapy programs in order to continue to advance and,
in the future, commercialize these programs.

13

We and CRISPR rely on third-party manufacturers to produce or process cell culture reagents, gene-editing components, such as Cas9 protein and guide
RNA molecules, and to generate gene-edited cells to supply CTX001 for clinical trials. If approved, we expect to continue to rely on third-party manufacturers
for commercial supply of CTX001. The current manufacturing process for CTX001 involves a number of steps prior to the final infusion of drug product into
patients. Following mobilization and collection of blood cells from the patient at the clinical site, cells are transferred to a manufacturing site where HSPCs
are purified and CRISPR/Cas9 gene-editing is performed. The edited cellular product, called CTX001, is frozen and transported back to the clinical site where
it is stored prior to infusion into the patient. Each step must be completed successfully, and in a timely manner, requiring coordination between CRISPR,
Vertex, clinical sites, third-party manufacturers and shipping vendors. To increase production to commercial levels, Vertex and CRISPR will need to
coordinate manufacturing and logistics activities at a larger scale across multiple facilities in the geographies in which CTX001 is approved. Approval will
rely on inspection and approval of these facilities by global health authorities.

COMPETITION

The pharmaceutical industry is characterized by extensive research efforts, rapid technological progress and intense competition. There are many public
and private companies, including pharmaceutical companies and biotechnology companies, engaged in developing products for the indications our drugs are
approved to treat and the therapeutic areas we are targeting with our research and development activities. Potential competitors also include academic
institutions, government agencies, other public and private research organizations and charitable venture philanthropy organizations that conduct research,
seek patent protection and/or establish collaborative arrangements for research, development, manufacturing and commercialization. Mergers and acquisitions
in the pharmaceutical, biotechnology and gene therapy industries may result in a larger concentration of resources among a smaller number of our competitors.
Some of our competitors may have substantially greater financial, technical, marketing and human resources than we do.

We believe that competition in our industry is based on, among other factors, innovative research, the effective and rapid development of drug candidates,

the ability to market and obtain reimbursement for products and the ability to establish effective patent protection. We face competition based on the safety
and efficacy of our product and drug candidates, the timing and scope of regulatory approvals, the availability and cost of supply, marketing and sales
capabilities, reimbursement coverage, price, patent protection and other factors. Our competitors may develop or commercialize more effective, safer or more
affordable products than we are able to develop or commercialize or obtain more effective patent protection. As a result, our competitors may commercialize
products more rapidly or effectively than we do, which would adversely affect our competitive position, the likelihood that our drug candidates, if approved,
would achieve and maintain market acceptance and our ability to generate meaningful revenues from our products. Future competitive products may render
our products, or future products, obsolete or noncompetitive. Another key element of remaining competitive in our industry is recruiting and retaining leading
scientific, technical and management personnel to conduct our research activities and advance our development programs, including with the commercial
expertise to effectively market our products.

Cystic Fibrosis

A number of companies are seeking to identify and develop drug candidates for the treatment of CF, including CFTR modulators and other therapies

intended to address the underlying causes of CF.

AbbVie, Inc., or AbbVie, has indicated that it plans to develop a triple combination CFTR modulator therapy comprised of a potentiator and correctors.
Currently, AbbVie is evaluating the combination of a potentiator and a corrector in a Phase 2 clinical trial. In March 2020, AbbVie disclosed plans to file an
IND application with the FDA for another corrector in the second quarter of 2020. In addition, Proteostasis Therapeutics, Inc. was developing potential CFTR
modulator therapies prior to its acquisition by Yumanity Therapeutics, Inc., or Yumanity. Following the merger, Yumanity has announced plans to divest its CF
program.

Other therapeutic approaches include addressing CF utilizing nucleic acid therapies and read-through agents, which are compounds that allow expression

of a full-length protein. Nucleic acid therapies are under development by companies such as Translate Bio, Arcturus Therapeutics Holdings, Inc., Krystal
Biotech, Inc., Spirovant Sciences, Inc. and 4D Molecular Therapeutics, Inc. Translate Bio is evaluating its mRNA therapy in a proof of concept Phase 1/2
clinical trial. Eloxx Pharmaceuticals, Inc. is evaluating a read-through therapy for nonsense CFTR mutations in two Phase 2 clinical trials.

14

Our success in rapidly developing and commercializing our products may increase the resources that our competitors allocate to the development of these

potential treatments for CF. If one or more competing therapies are successfully developed as a treatment for people with CF, our revenues from our current
products and/or additional CF products, if then approved, could face significant competitive pressure.

Pipeline

In recent years, we have committed significant research resources to, and made significant investments in, our pipeline of potential new therapies for AAT

deficiency, APOL1-mediated kidney diseases, TDT, SCD, muscular dystrophies, T1D and other diseases. We plan to continue investing in our pipeline,
including expanding beyond small molecule therapies and into the discovery and development of cell and gene therapies. For example, we remain focused on
our ongoing evaluation of CTX001, an investigational CRISPR/Cas9-based gene-editing therapy, for treatment of SCD and TDT currently in clinical
development.

There are multiple approved treatments for TDT and SCD, including products from Novartis International AG, or Novartis, Global Blood Therapeutics,
Inc. and Bristol Myers Squibb together with Acceleron Pharma, Inc. Bluebird Bio, Inc., or Bluebird, has a gene therapy, Zynteglo (Lentiglobin), approved by
the European Medicines Agency, or EMA, for the treatment of certain TDT genotypes and in clinical development for SCD. In addition, various companies
and private academic/medical institutes are developing gene therapy or gene-editing candidates for the treatment of SCD or TDT utilizing CRISPR
technology, lenti-viral vectors, zinc finger nuclease technology, or base editing.

Many other pharmaceutical and biotechnology companies are also investing resources for discovery and development of small molecules, gene therapies

and cell therapies to treat the same diseases for which we are developing therapies. If any of these competitors develop or successfully commercialize products
involving therapies competitive with our pipeline therapies, the potential return on our investment in those pipeline therapies could be impacted.

GOVERNMENT REGULATION

Our operations and activities are subject to extensive regulation by numerous government authorities in the U.S., the E.U. and other countries. In the U.S.,

the E.U. and other countries, drugs are subject to rigorous regulations governing the testing, manufacture, labeling, storage, record keeping, approval,
advertising and promotion of our products. As a result of these regulations, product development and product approval processes are very expensive and time
consuming. The regulatory requirements applicable to drug development, approval, and marketing are subject to change. In addition, regulations and
administrative guidance often are revised or reinterpreted by the agencies in ways that may significantly affect our business and our products. It is impossible
to predict whether legislative changes will be enacted, or FDA or comparable ex-U.S. regulations, guidance or interpretations will change.

United States Government Regulation

New Drug Application Approval Processes

The process required by the FDA before a drug may be marketed in the U.S. generally involves the following:

•    completion of preclinical laboratory tests, animal studies and formulation studies conducted according to Good Laboratory Practices, or GLP, and

other applicable regulations;

•    submission to the FDA of an IND application, which must become effective before clinical trials in the U.S. may begin;

•    performance of adequate and well-controlled clinical trials according to Good Clinical Practices, or GCP, to establish the safety and efficacy of the

proposed drug for its intended use;

•    submission to the FDA of a New Drug Application, or an NDA;

•    satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product will be produced to assess compliance

with cGMP; and

•    FDA review and approval of the NDA.

15

Once a drug candidate is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product
chemistry, toxicity and formulation, as well as animal pharmacology and toxicology studies. An IND sponsor must submit the results of the preclinical tests,
together with manufacturing information and analytical data, to the FDA as part of the IND, which seeks FDA approval to test the drug candidate in humans.
Preclinical or nonclinical testing typically continues even after the IND is submitted.

If the FDA accepts the IND, the drug candidate can then be studied in human clinical trials to determine if the drug candidate is safe and effective. These

clinical trials involve three separate phases that often overlap, can take many years and are expensive. These three phases, which are subject to considerable
regulation, are as follows:

•    Phase 1. The drug initially is introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and

elimination. In the case of some drug candidates for severe or life-threatening diseases, such as cancer, especially when the drug candidate may be
inherently too toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

•    Phase 2. Clinical trials are initiated in a limited patient population intended to identify possible adverse effects and safety risks, to preliminarily

evaluate the efficacy of the drug candidate for specific targeted diseases and to determine dosage tolerance and optimal dosage.

•    Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically

dispersed clinical trial sites. These clinical trials are intended to establish the overall risk-benefit ratio of the drug candidate and provide an adequate
basis for regulatory approval and product labeling.

Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within any specified period, if at all. The FDA or the sponsor may suspend a

clinical trial at any time for a variety of reasons, including a finding that the healthy volunteers or patients are being exposed to an unacceptable health risk.
All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP. Progress reports detailing the results
of the clinical trials must be submitted at least annually to the FDA and more frequently in other situations, including the occurrence of serious adverse events.
Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health for public dissemination on the
www.clinicaltrials.gov website.

The results of drug development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on

the chemistry of the drug candidate, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to
market the drug candidate. The FDA reviews each NDA submitted to ensure that it is sufficiently complete for substantive review before it accepts it for
filing. It may request additional information rather than accept an NDA for filing.

Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA reviews an NDA to determine, among other things, whether a
drug candidate is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the drug candidate’s identity,
strength, quality and purity. The FDA may refer the NDA to an advisory committee for review and recommendation as to whether the NDA should be
approved and under what conditions. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such
recommendations. Before approving an NDA, the FDA will inspect the facility or facilities where the drug candidate is manufactured and tested. Additionally,
before approving an NDA, the FDA may inspect one or more clinical trial sites to assure compliance with GCP requirements.

The FDA may require, as a condition of approval, restricted distribution and use, enhanced labeling, special packaging or labeling, expedited reporting of

certain adverse events, pre-approval of promotional materials, restrictions on direct-to-consumer advertising or commitments to conduct additional research
post-approval. The FDA will issue a complete response letter if the agency decides not to approve the NDA in its present form.

Biologics License Application Process

Certain of our drug candidates may be regulated by the FDA under the Food, Drug, and Cosmetic Act, or FDCA, and the Public Health Service Act as
biologics. Biologics can present special safety, efficacy and manufacturing challenges that may differ from those present in the regulation of small molecule
drugs. As such, while similar to the NDA review process described above, in lieu of filing an NDA, biologics require the submission of a Biologics License
Application, or BLA, and approval of such BLA by the FDA prior to being marketed in the U.S.

16

Expedited Review and Approval

The FDA has developed a number of distinct approaches to make new drugs available as rapidly as possible in cases where there is no available treatment

or there are advantages over existing treatments.

The FDA may grant “accelerated approval” to products that have been studied for their safety and effectiveness in treating serious or life-threatening
illnesses and that provide meaningful therapeutic benefit to patients over existing treatments. For accelerated approval, the product must have an effect on a
surrogate endpoint or an intermediate clinical endpoint that is considered reasonably likely to predict the clinical benefit of a drug, such as an effect on
irreversible morbidity and mortality. When approval is based on surrogate endpoints or clinical endpoints other than survival or morbidity, the sponsor will be
required to conduct additional post-approval clinical studies to verify and describe the clinical benefit. These studies are known as “confirmatory trials.”
Approval of a drug may be withdrawn, or the labeled indication of the drug changed if these trials fail to verify clinical benefit or do not demonstrate
sufficient clinical benefit to justify the risks associated with the drug.

The FDA may grant “fast track” status to products that treat serious diseases or conditions and demonstrate the potential to address an unmet medical
need. Fast track is a process designed to facilitate the development and expedite the review of such products by providing, among other things, more frequent
meetings with the FDA to discuss the product’s development plan and rolling review, which allows submission of individually completed sections of an NDA
or BLA for FDA review before the entire submission is completed. Fast track status does not ensure that a product will be developed more quickly or receive
FDA approval.

“Breakthrough Therapy” designation is a process designed to expedite the development and review of drugs that are intended to treat a serious condition
and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint.
For drugs and biologics that have been designated as Breakthrough Therapies, robust FDA-sponsor interaction and communication can help to identify the
most efficient and expeditious path for clinical development while minimizing the number of patients placed in ineffective control regimens.

“Regenerative Medicine Advanced Therapy,” or RMAT, designation is a process created by the 21st Century Cures Act in December 2016. A product is
eligible for RMAT designation if it is a regenerative medicine therapy that is intended to treat, modify, reverse or cure a serious or life-threatening disease or
condition, and preliminary clinical evidence indicates that the product has the potential to address unmet medical needs for such disease or condition. The
benefits of RMAT designation include the benefits available to breakthrough therapies, including potential eligibility for priority review and accelerated
approval based on surrogate or intermediate endpoints.

The FDA may grant “priority review” status to products that, if approved, would provide significant improvement in the safety or effectiveness of the
treatment, diagnosis, or prevention of serious conditions. Priority review is intended to reduce the time it takes for the FDA to review an NDA or BLA, with
the goal to take action on the application within six months from when the application is filed, compared to ten months for a standard review.

Manufacturing Quality Control

Among the conditions for NDA or BLA approval is the requirement that the prospective manufacturer’s quality control and manufacturing procedures

continually conform with cGMP. In complying with cGMP, manufacturers must devote substantial time, money and effort in the areas of production, quality
control and quality assurance to maintain compliance. Material changes in manufacturing equipment, location or process, may result in additional regulatory
review and approval. The FDA, and other regulatory agencies, conduct periodic visits to inspect equipment, facilities, and processes following the initial
approval of a product. If a manufacturing facility is not in substantial compliance with the applicable regulations and requirements imposed when the product
was approved, regulatory enforcement action may be taken, which may include a warning letter or an injunction against shipment of products from the facility
and/or recall of products previously shipped. We rely, and expect to continue to rely, on third parties for the production of our products. Future FDA, state, and
foreign inspections may identify compliance issues at the facilities of our contract manufacturers that may disrupt manufacture or distribution of our products
or require substantial resources to correct.

17

Post-approval Requirements

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory standards is not maintained or if problems occur after the
product reaches the market. Later discovery of previously unknown problems with a product may result in restrictions on the product or complete withdrawal
of the product from the market. In addition, under the FDCA the sponsor of an approved drug in the U.S. may not promote that drug for unapproved, or off-
label, uses, although a physician may prescribe a drug for an off-label use in accordance with the practice of medicine. After approval, some types of changes
to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further FDA review and
approval. In addition, the FDA may require testing and surveillance programs to monitor the effect of approved products that have been commercialized, and
the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs.

Products manufactured or distributed by us pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things:

•    record-keeping requirements;

•    reporting of adverse experiences with the product;

•    providing the FDA with updated safety and efficacy information;

•    drug sampling and distribution requirements;

•    notifying the FDA and gaining its approval of specified manufacturing or labeling changes;

•    complying with certain electronic records and signature requirements; and

•    complying with FDA promotion and advertising requirements.

Failure to comply with the applicable U.S. requirements at any time during the drug development process, approval process or after approval, may subject

us or our collaborators to administrative or judicial sanctions, any of which could have a material adverse effect on us. These sanctions could include:

•    refusal to approve or delay in review of pending applications;

•    withdrawal of an approval or the implementation of limitations on a previously approved indication for use;

•    imposition of a clinical hold, a risk mitigation and evaluation strategy or other safety-related limitations;

•    warning letters or “untitled letters”;

•    product seizures;

•    total or partial suspension of production or distribution; or

•    injunctions, fines, disgorgement, refusals of government contracts, or civil or criminal penalties.

Patent Term Restoration and Regulatory Exclusivity

Upon approval, products may be entitled to certain kinds of exclusivity under applicable intellectual property and regulatory regimes. The Drug Price
Competition and Patent Term Restoration Act of 1984 (commonly known as the Hatch-Waxman Act) permits a patent restoration term of up to five years as
compensation for patent term lost during product development and the FDA regulatory review process. The length of the patent extension is roughly based on
50 percent of the period of time from the filing of an IND for a compound to the submission of the NDA for such compound, plus 100 percent of the time
period from NDA submission to regulatory approval. The extension, however, cannot exceed five years and the patent term remaining after regulatory
approval cannot exceed 14 years.

If the FDA approves a drug product that contains an active ingredient not previously approved, the product is typically entitled to five years of non-patent

regulatory exclusivity. Other products may be entitled to three years of exclusivity if approval was based on the FDA’s reliance on new clinical studies
essential to approval submitted by the NDA applicant. If

18

the NDA applicant studies the product for use by children, the FDA may grant pediatric exclusivity, which extends by 180 days each existing exclusivity
(patent and regulatory) related to the product.

Biologics are also entitled to exclusivity under the Biologics Price Competition and Innovation Act, which was passed as Title VII to the ACA. The law

provides a pathway for approval of biosimilars following the expiration of 12 years of exclusivity for the innovator biologic and a potential additional 180
day-extension term for conducting pediatric studies. Biologics are also eligible for orphan drug exclusivity, as discussed below. The law also includes an
extensive process for the innovator biologic and biosimilar manufacturer to litigate patent infringement, validity, and enforceability prior to the approval of the
biosimilar. There have been ongoing federal legislative and administrative efforts as well as judicial challenges seeking to repeal, modify or invalidate some or
all of the provisions of the ACA. While none of those efforts have focused on changes to the provisions of the ACA related to the biosimilar regulatory
framework, if the ACA is repealed, substantially modified, or invalidated, it is unclear what, if any, impact such action would have on biosimilar regulation.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drug candidates intended to treat a rare disease or condition, which is

generally a disease or condition that affects fewer than 200,000 people in the U.S.

If a drug candidate that has orphan drug designation subsequently receives the first FDA approval for that drug for the disease for which it has such
designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same drug for
the same indication for seven years following marketing approval, except in certain very limited circumstances, such as if the later product is shown to be
clinically superior to the orphan product. Orphan drug exclusivity, however, also could block the approval of our drug candidates for seven years if a
competitor first obtains approval of the same product as defined by the FDA or if our drug candidate is determined to be contained within the competitor’s
product for the same indication or disease. KALYDECO, ORKAMBI, SYMDEKO, and TRIKAFTA have been granted orphan drug exclusivity by the FDA.

Foreign Regulation

We conduct clinical trials and market our products in numerous jurisdictions outside the U.S. Most of these jurisdictions have clinical trial, product

approval and post-approval regulatory processes that are similar in principle to those in the U.S. Thus, whether or not we obtain FDA approval for a drug
candidate, we must obtain approval by the comparable regulatory authorities of foreign countries or economic areas, such as the E.U., before we can
commence clinical trials or market products in those countries or areas. The approval process and requirements governing the conduct of clinical trials,
product licensing, pricing and reimbursement vary greatly from place to place, and the time may be longer or shorter than that required for FDA approval.

Under E.U. regulatory systems, a company may submit marketing authorization applications either under a centralized or decentralized procedure. The
centralized procedure, which is compulsory for medicines produced by biotechnology or those medicines intended to treat AIDS, cancer, neurodegenerative
disorders, or diabetes and optional for those medicines that are highly innovative, provides for the grant of a single marketing authorization that is valid for all
E.U. member states. In addition to the centralized procedure, Europe also has a nationalized procedure, which requires a separate application to and approval
determination by each country; a decentralized procedure, whereby applicants submit identical applications to several countries and receive simultaneous
approval; and a mutual recognition procedure, where applicants submit an application to one country for review and other countries may accept or reject the
initial decision.

Other Regulations

Pharmaceutical companies are also subject to various laws pertaining to healthcare “fraud and abuse,” including anti-kickback and false claims laws.
Anti-kickback laws generally make it illegal to knowingly and willfully solicit, offer, receive or pay any remuneration in return for or to induce the referral of
business, including the purchase or prescription of a particular drug that is reimbursed by a state or federal health care program. False claims laws prohibit
knowingly and willingly presenting, or causing to be presented for payment to third-party payors (including Medicare and Medicaid), any claims for
reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed or claims for medically unnecessary items or
services. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as by
the possibility of exclusion from federal healthcare programs (including Medicare and Medicaid). Liability under the false claims laws may also arise when a
violation of certain laws or regulations related to the underlying products (e.g., violations regarding improper promotional activity or unlawful

19

payments) contributes to the submission of a false claim. If we were subject to allegations concerning, or convicted of violating, these laws, our business could
be harmed.

Laws and regulations also have been enacted by the federal government and various states to regulate the sales and marketing practices of pharmaceutical

manufacturers. The laws and regulations generally limit financial interactions between manufacturers and health care providers, require manufacturers to
adopt certain compliance standards or require disclosure to the government and public of such interactions. The laws include U.S. federal and state “sunshine”
provisions. The federal sunshine provisions apply to pharmaceutical manufacturers with products reimbursed under certain government programs and require
those manufacturers to disclose annually to the federal government (for re-disclosure to the public) certain payments and other transfers of value made to
physicians and teaching hospitals and, beginning with disclosures in 2022, to certain non-physician practitioners. State laws may also require disclosure of
pharmaceutical pricing information and marketing expenditures. Many of these laws and regulations contain requirements that are subject to interpretation.
Outside the U.S., other countries have implemented requirements for disclosure of financial interactions with healthcare providers and additional countries
may consider or implement such laws.

We are subject to various federal and foreign laws that govern our international business practices with respect to payments to government officials.
Those laws include the U.S. Foreign Corrupt Practices Act, or FCPA, which prohibits U.S. companies and their representatives from paying, offering to pay,
promising, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate
for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. In many
countries, the health care professionals we regularly interact with may meet the FCPA’s definition of a foreign government official. We are also subject to U.K.
Bribery Act 2010, or the Bribery Act, which proscribes giving and receiving bribes in the public and private sectors, bribing a foreign public official, and
failing to have adequate procedures to prevent employees and other agents from giving bribes. U.S. companies that conduct business in the United Kingdom,
or U.K., generally will be subject to the Bribery Act.

We are subject to federal laws, including the Medicaid Drug Rebate Program, that require pharmaceutical manufacturers to report certain calculated
product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement
under government healthcare programs.

Our collection and use of personal data as part of our business activities is subject to various privacy and data security laws and regulations, including
oversight by various regulatory or other governmental bodies, in the U.S., E.U., U.K., Canada, Australia and other jurisdictions. Such laws and regulations
have the potential to affect our business materially, continue to evolve and increasingly are being enforced.

Our present and future business has been and will continue to be subject to various other laws and regulations. Various laws, regulations and

recommendations relating to safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import,
export and use and disposal of hazardous or potentially hazardous substances are or may be applicable to our activities. In addition, as we expand our pipeline
and contemplate different approaches that may incorporate the use of medical devices, such approaches may necessitate compliance with regulatory laws
applicable to medical devices, including those governing the testing, manufacture, approval, distribution, and marketing of medical devices. Furthermore, the
extent of government regulation, which might result from future legislation or administrative action, cannot accurately be predicted.

We have a corporate compliance program designed to actively identify, prevent and mitigate risk through the implementation of compliance policies and
systems and through the promotion of a culture of compliance. We expect to continue to devote substantial resources to maintain, administer and expand the
compliance program globally. We cannot be certain, however, that our compliance program will ensure compliance with the various complex laws and
regulations to which we are subject now or in the future.

EMPLOYEES AND HUMAN CAPITAL MANAGEMENT

As of December 31, 2020, we had approximately 3,400 employees. Of these employees, approximately 2,800 were based in the U.S. and approximately

600 were based outside the U.S. Our employees are not covered by a collective bargaining agreement, except for a small number of employees outside the
U.S. We consider our relations with our employees to be good. We continue to face intense competition for our personnel from our competitors and other
companies throughout our industry and from universities and research institutions.

We rely on skilled, experienced, and innovative employees to conduct the operations of our company. The biotechnology industry is very competitive and

recruiting and retaining such employees is important to the continued success of our business. We are committed to building an outstanding, committed and
passionate team at Vertex, and we focus on a culture that values inclusion, diversity and equity. We believe that each employee brings unique perspectives and
strengths, and by embracing these strengths, we can do our best work for patients. We focus on recruiting, retaining, and developing employees from a diverse
range of backgrounds to conduct our research, development, and commercial activities.

Our commitment to diversity, inclusion and equity begins with our executive management team: four of our ten members are women and/or from diverse

racial and ethnic groups. On our Board of Directors, six of our ten members are women and/or from a diverse racial and ethnic group. As of December 31,
2020, women represented 53% of our global workforce and 38% of our leadership (VP and above). As of December 31, 2020, 34% of our U.S. workforce, and
18% of our U.S. leadership (VP and above), were from diverse racial and ethnic groups.

The leader of our diversity, inclusion, and equity strategy and efforts is a Vice President in our human resources group. Additionally, our employee resource
networks promote connectivity and collaboration across levels and functions, and engage colleagues in personal and professional development opportunities,
including mentoring, community outreach, and cultural awareness activities.

To promote our employees’ continued well-being and development, we offer a variety of inclusive benefits and opportunities. We offer comprehensive

work-life benefits, including health, dental, and income protection, such as life insurance and retirement savings programs. In 2020, we enhanced and
expanded our employee benefits in response to the COVID-19 pandemic. For example, we increased company-wide personal time off, provided resources to
enable employees to work from home, and introduced and expanded mental wellness tools for all employees. Our management has continued to assess and
respond to the evolving needs of our workforce throughout the pandemic.

In addition, we provide our employees with career development and advancement opportunities, including job rotations, mentoring and managerial
training. We also are committed to identifying and developing our next generation leaders and have developed programs focused on talent and succession for
critical roles in our organization.

Succession Planning

In 2020, we successfully executed a leadership succession plan with the transition of Dr. Kewalramani to the role of Chief Executive Officer and our
former Chief Executive Officer, Dr. Leiden, to the role of Executive Chairman. This transition was the culmination of a multi-year planning process led by our
independent directors.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk, and you should carefully consider the risks and uncertainties described below in addition to
the other information included or incorporated by reference in this Annual Report on Form 10-K. If any of the following risks or uncertainties actually occurs,
our business, financial condition or results of operations would likely suffer, possibly materially. In that case, the trading price of our common stock could
decline.

SUMMARY OF RISK FACTORS

Our business is subject to numerous risks and uncertainties, discussed in more detail in the following section. These risks include, among others, the

following key risks:

Risks Related to Our Business

• All of our product revenues and the vast majority of our total revenues are derived from sales of medicines for the treatment of CF. If we are unable to

continue to increase revenues from sales of our CF medicines, our business would be materially harmed and the market price of our common stock would
likely decline.

• We are investing significant resources in the research and development of therapies for serious diseases other than CF, and if we are unable to successfully

commercialize one or more of these therapies, our business could be materially harmed.

•

•

•

If our competitors bring drugs with superior product profiles to market, our drugs may not be competitive and our revenues could decline.

If we discover safety issues with any of our products or if we fail to comply with continuing U.S. and applicable foreign regulations, commercialization
efforts for the product could be negatively affected, the approved product could lose its approval or sales could be suspended, and our business could be
materially harmed.

If physicians and patients do not accept our medicines, or if patients do not remain on treatment or comply with their prescribed dosing regimen, our
product revenues would be materially harmed in future periods.

• Government and other third-party payors seek to contain costs of health care through legislative and other means. If they fail to provide coverage and

adequate reimbursement rates for our products, our revenues will be harmed.

• We have experienced challenges commercializing products outside of the U.S, and our future revenues will be dependent on our ability to obtain adequate

reimbursement for our products.

• We have limited experience developing cell and genetic therapies and could experience challenges with these programs, which could result in delays or

prevent the development, manufacturing and commercialization of our cell and genetic therapies.

Risks Related to Development and Clinical Testing of Our Products and Drug Candidates

• Our drug candidates remain subject to clinical testing and regulatory approval. Our future success is dependent on our ability to successfully develop

additional drug candidates for both CF and non-CF indications.

•

•

If we are unable to obtain regulatory approval, we will be unable to commercialize our drug candidates.

If clinical trials are prolonged or delayed, our development timelines for the affected development program could be extended, our costs to develop the
drug candidate could increase and the competitive position of the drug candidate could be adversely affected.

Risks Related to Government Regulation

•

If regulatory authorities interpret any of our conduct, including our marketing practices, as being in violation of applicable health care laws, including
fraud and abuse laws, laws prohibiting off-label promotion, disclosure laws or other similar laws, we may be subject to civil or criminal penalties.

26

•

•

If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other governmental pricing programs in the
U.S., we could be subject to additional reimbursement requirements, penalties, sanctions and fines which could have a material adverse effect on our
business, financial condition, results of operations and growth prospects.

If our processes and systems are not compliant with regulatory requirements, we could be subject to restrictions on marketing our products or could be
delayed in submitting regulatory filings seeking approvals for our drug candidates.

• We are subject to various and evolving laws and regulations governing the privacy and security of personal data, and our failure to comply could

adversely affect our business, result in fines and/or criminal penalties, and damage our reputation.

Risks Related to Business Development Activities

• Our ability to execute on our long-term strategy depends in part on our ability to engage in transactions and collaborations with other entities that add to

our pipeline or provide us with new commercial opportunities.

• We may not realize the anticipated benefits of acquisitions of businesses or technologies, and the integration following any such acquisition may disrupt

our business and management.

• We face risks in connection with existing and future collaborations with respect to the development, manufacture and commercialization of our products

and drug candidates.

• We may not be able to attract collaborators or external funding for the development and commercialization of certain of our drug candidates.

Risks Related to Third-Party Manufacturing and Reliance on Third Parties

• We depend on third-party manufacturers to manufacture our products and the materials we require for our clinical trials. We may not be able to maintain

these relationships and could experience supply disruptions outside of our control.

• We rely on third parties to conduct pre-clinical work, clinical trials and other activities, and those third parties may not perform satisfactorily, including

failing to meet established deadlines for the completion of such studies and/or trials or failing to satisfy regulatory requirements.

Risks Related to Intellectual Property

•

If our patents do not protect our drugs or our drugs infringe third-party patents, we could be subject to litigation which could result in injunctions
preventing us from selling our products or substantial liabilities.

• Uncertainty over intellectual property in the pharmaceutical and biotechnology industry has been the source of litigation and other disputes, which is

inherently costly and unpredictable.

• We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of

what we regard as our own intellectual property.

Risks Related to Our Operations

•

Risks associated with operating in foreign countries could materially adversely affect our business.

• We are subject to risks associated with the global COVID-19 pandemic.

•

If we fail to attract and retain skilled employees, our business could be materially harmed.

• Our business faces potential risks relating to the United Kingdom’s withdrawal from the European Union.

Risks Related to Financial Results and Holding Our Common Stock

• Our stock price may fluctuate.

•

Changes in tax laws, regulations and treaties could affect our future taxable income.

27

Risks Related to Our Business

All of our product revenues and the vast majority of our total revenues are derived from sales of medicines for the treatment of CF. If we are unable to
continue to increase revenues from sales of our CF medicines, our business would be materially harmed and the market price of our common stock would
likely decline.

Our net product revenues and the vast majority of our total revenues are derived from the sale of our CF medicines. As a result, our future success is
dependent upon our ability to increase revenues from sales of our CF medicines. This will require us to continue to gain approval and reimbursement for our
triple combination therapy in ex-U.S. markets and successfully develop and commercialize our triple combination therapy for younger children with CF.

Our concentrated source of revenues presents a number of risks to our business, including:

•

•

•

•

that one or more competing therapies may successfully be developed as a treatment for people with CF;

that reimbursement policies of payors and other third parties may make it difficult to obtain reimbursement or reduce the net price we receive for our
products;

that we may experience manufacturing or supply disruptions for our CF medicines; and

that we may experience adverse developments with respect to development or commercialization of our CF medicines and/or CF drug candidates.

If any of the above risks were to materialize, if we are otherwise unable to increase revenues from sales of our CF medicines, or if we do not meet the
expectations of investors or public equity market analysts, our business would be materially harmed and our ability to fund our operations could be adversely
affected. For example, if we are unable to increase revenues from sales of our CF medicines, our ability to fund our research and development programs for
the discovery and development or acquisition of new products would be harmed, which would limit our ability to diversify our revenue base and our stock
price would likely be adversely affected.

We are investing significant resources in the research and development of therapies for serious diseases other than CF, and if we are unable to
successfully commercialize one or more of these therapies, our business could be materially harmed.

We are investing significant resources in the research and development of medicines for serious diseases including AAT deficiency, APOL1-mediated
kidney diseases, pain, beta thalassemia, SCD, T1D, DMD and DM1. Some of these programs have progressed into clinical trials, while others are still in pre-
clinical development. Product development is highly uncertain and expensive, and product candidates that may appear promising in the early phases of
research and development may fail to reach commercial success for many reasons, including the failure to demonstrate acceptable clinical trial results or
obtain marketing approval, the inability to manufacture or commercialize the product candidate on economically feasible terms, or the appearance of safety
issues. For example, in October 2020, we discontinued development of VX-814, a drug candidate for the treatment of AAT, based on the safety and
pharmacokinetic profile observed in a Phase 2 clinical trial.

Even if we gain marketing approval for one or more pipeline products, we cannot be sure that we will obtain market acceptance or adequate

reimbursement levels from third-party payors or foreign governments for such products. Additionally, many of the therapies that we are developing in our
pipeline target rare diseases that affect a limited number of patients. There can be no guarantee that we will effectively identify patients that are eligible for
enrollment in our clinical trials or treatment with our drug candidates. Even if we do successfully identify eligible patients, the number of patients that our
drug candidates are able to treat may turn out to be lower than we expect or new patients may become increasingly difficult to identify, each of which may
adversely affect our revenues and materially harm our business. For these and other reasons, we may never be successful in expanding our pipeline and future
revenue may continue to depend on sales of our CF medicines.

28

If our competitors bring drugs with superior product profiles to market, our drugs may not be competitive and our revenues could decline.

A number of companies are seeking to identify and develop drug candidates for the treatment of CF and other therapeutic areas we are targeting with our

research and development activities. Our success in rapidly developing and commercializing our CF medicines may increase the resources that our
competitors allocate to the development of potential competitive treatments. If one or more competing therapies are successfully developed as a treatment for
people with CF or any of the other diseases we are currently targeting in our pipeline, our products and our net product revenues could face competitive
pressures. If one or more competing therapies prove to be superior to our then existing products and/or drug candidates, our business could be materially
adversely affected.

In addition, our business faces competition from major pharmaceutical companies possessing substantially greater financial resources than we possess.

We also face competition from numerous smaller public and private companies, academic institutions, government agencies, public and private research
organizations and charitable venture philanthropy organizations that conduct research, seek patent protection and/or establish collaborative arrangements for
research, development, manufacturing and commercialization.

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller

number of our competitors. Smaller and other early-stage companies also may prove to be significant competitors, particularly through collaborative
arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management
personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our
programs.

Our products and any drugs that we develop in the future may not be able to compete effectively with marketed drugs or new drugs that may be developed

by competitors. The risk of competition is particularly important to our company because substantially all of our revenues as well as our most advanced drug
candidates are related to the treatment of people with CF. There are many other companies developing drugs for the same patient populations that we are
pursuing. In order to compete successfully in these areas, we must demonstrate improved safety, efficacy and/or tolerability, ease of manufacturing, and gain
and maintain market acceptance over competing drugs.

If we discover safety issues with any of our products or if we fail to comply with continuing U.S. and applicable foreign regulations, commercialization
efforts for the product could be negatively affected, the approved product could lose its approval or sales could be suspended, and our business could be
materially harmed.

Our products are subject to continuing regulatory oversight, including the review of additional safety information. Drugs are more widely used by patients
once approval has been obtained and therefore side effects and other problems may be observed after approval that were not seen or anticipated, or were not as
prevalent or severe, during pre-approval clinical trials or nonclinical studies. The subsequent discovery of previously unknown or underestimated problems
with a product could negatively affect commercial sales of the product, result in restrictions on the product or lead to the withdrawal of the product from the
market. Three of our commercial products are combination products, and each of our products shares at least one active pharmaceutical ingredient with
another of our products. As a result, if any of our CF products were to experience safety issues, our other CF products may be adversely affected. The
reporting of adverse safety events involving our products or public speculation about such events could cause our stock price to decline or experience periods
of volatility. Our business also may be materially harmed by impaired sales of our products, denial or withdrawal of regulatory approvals, required label
changes or additional clinical trials, reputational harm, or government investigations or lawsuits brought against us.

In addition, our products are subject to ongoing regulatory requirements governing the testing, manufacturing, labeling, packaging, storage, advertising,
promotion, sale, distribution, import, export, recordkeeping and submission of safety and other post-market information. We and our third-party manufacturers
must comply with cGMP and other applicable regulations governing the manufacturing and distribution of our products. Regulatory authorities periodically
inspect our drug manufacturing facilities, and those of our third-party manufacturers, to evaluate compliance with cGMP and other regulatory requirements.

If we or our collaborators, or third-parties acting on our behalf, fail to comply with applicable continuing regulatory requirements, we or our collaborators

may be subject to fines, suspension or withdrawal of regulatory approvals for specific

29

products, product recalls and seizures, operating restrictions and/or criminal prosecutions, any of which could have a material adverse effect on our business,
reputation, financial condition and results of operations.

If physicians and patients do not accept our medicines, or if patients do not remain on treatment or comply with their prescribed dosing regimen, our
product revenues would be materially harmed in future periods.

Our medicines may not gain or maintain market acceptance among physicians and patients. Effectively marketing our drugs and any of our drug

candidates or investigational therapies, if approved, requires substantial efforts, both prior to launch and after approval. Physicians may elect not to prescribe
our drugs or recommend our cell or genetic therapies, and patients may elect not to take them or receive them or they may discontinue use of our drugs after
initiation of treatment, for a variety of reasons including:

•    prevalence and severity of adverse side effects;

•    lack of reimbursement availability from third-party payors, including governmental entities;

•    lower demonstrated efficacy, safety and/or tolerability compared to alternative treatment methods;

•    lack of cost-effectiveness;

•    a decision to wait for the approval of other therapies in development that have significant perceived advantages over our drug;

•    convenience and ease of administration;

•    other potential advantages of alternative treatment methods; and

•    inadequate sales, marketing and/or distribution support, including as a result of limitations or restrictions resulting from COVID-19.

If our medicines fail to achieve or maintain market acceptance, we may not be able to generate significant revenues in future periods.

Government and other third-party payors seek to contain costs of health care through legislative and other means. If they fail to provide coverage and
adequate reimbursement rates for our products, our revenues will be harmed.

Sales of our products depend in part upon the availability of reimbursement from third-party payors. Third-party payors include government health
programs such as Medicare and Medicaid in the U.S. and the national health care systems in ex-U.S. markets, managed care providers, private health insurers
and other organizations. The trend in the health care industry is cost containment, and efforts of third-party payors to contain or reduce health care costs may
adversely affect our ability to establish or maintain appropriate prices for our products or any drugs that we may develop and commercialize.

In most ex-U.S. markets, the pricing and reimbursement of therapeutic and other pharmaceutical products is subject to governmental control, and
government authorities are making greater efforts to limit or regulate the price of drug products. In the U.S., there have been, and we expect that there will
continue to be, a number of federal and state proposals to implement governmental controls that are similar to those that currently exist in Europe. For
example, the ACA required manufacturers of Medicare Part D brand name drugs to provide discounts on those drugs to Medicare Part D beneficiaries during
the coverage gap; increased the rebates paid by pharmaceutical companies to state Medicaid programs on drugs covered by Medicaid; and imposed an annual
fee, which increases annually, on sales by branded pharmaceutical manufacturers.

There also has been an increase in legislation and regulations related to drug pricing and drug pricing transparency. In the U.S., various states, including

Nevada, Maryland, Louisiana, New York, California, Washington, Massachusetts, Connecticut, Utah, Minnesota and Oregon, have passed legislation
requiring companies to disclose extensive information relating to drug prices, drug price increases, and spending on research, development, and marketing.
Although it is not clear what states will do with the collected information, some laws were designed to obtain additional product discounts. We may continue
to see more state action requiring additional disclosures or other actions. In addition, we could see increased federal activity related to drug pricing and
transparency requiring disclosures or other actions instead of, or in addition to, state requirements. Similar initiatives are also occurring in, or being considered
by, some of the ex-U.S. markets, including Italy and Brazil.

30

Complying with these laws is expensive and requires significant personnel and operational resources and deters focus on our business. Additionally, any
additional required discounts would adversely affect the pricing of, and revenues from, our products. Finally, while we seek to comply with all statutory and
regulatory requirements, we face increased enforcement activity by the U.S. federal government, state governments, and private payors against pharmaceutical
and biotechnology companies for pricing and reimbursement-related issues.

Recently, there also has been rulemaking related to importation of prescription drugs from Canada as well as guidance related to importation of
prescription drugs from other foreign countries. HHS also has issued a regulation seeking to establish a model for reference pricing of certain physician-
administered drugs. While the recent regulation does not apply to our current medicines, it could affect future medicines. Additionally, in 2020, the Trump
Administration issued several executive orders relating to drug pricing which were intended to broadly impact the pharmaceutical industry. Likewise, HHS
recently issued a final regulation adopting changes to anti-kickback laws for rebates offered to pharmacy benefit managers. We expect such government
scrutiny over drug pricing, reimbursement, and distribution to increase. Potential future government regulation of drug prices or reimbursement creates
uncertainties about our portfolio and could have a material adverse effect on our operations.

Third-party payors throughout the world also have been attempting to control drug spending through various other actions, and this is expected to be an
area of intensified focus for all payors in light of the global economic pressures, including due to the COVID-19 pandemic. In reimbursement negotiations,
many payors are demanding price discounts and caps on total expenditures and limiting both the types and variety of drugs that they will cover if they are not
able to secure them. As part of these negotiations, many ex-U.S. government payers also are requiring companies to establish product cost-effectiveness as a
condition of reimbursement and companies’ data-backed explanations are assessed by government agencies set up for this purpose. These cost-effectiveness
reviews may not account for many of the benefits provided by innovative medicines, and for the most part, have not taken into account the specific
circumstances of products that treat rare diseases. This has led to conclusions that certain medicines, including our products in certain jurisdictions, are not
cost-effective. As a result, certain countries have declined to reimburse, or delayed their reimbursement of, some of our products. Although not mandated in
the U.S., various organizations have started advocating for cost-effectiveness analyses in the U.S. If U.S. payors were to adopt such assessments and make
negative coverage determinations, it could adversely affect our product revenues. Our business would be materially adversely affected if we are not able to
obtain or maintain coverage and reimbursement of our products from third-party payors on a broad, timely or satisfactory basis or if such coverage is subject
to overly broad or restrictive utilization management controls.

The U.S. government, individual states and some foreign jurisdictions also have been aggressively pursuing legislative and regulatory reforms that could

affect our ability to sell products. For example, in the U.S., there have been ongoing federal legislative and administrative efforts to repeal, substantially
modify or invalidate some or all of the provisions of the ACA. Various portions of the ACA are subject to legal challenges in various jurisdictions, including
the U.S. Supreme Court, which could affect coverage and payment for medicines. Other reforms include the Bipartisan Budget Act of 2018, which contained
various provisions that affect coverage and reimbursement of drugs, including an increase in the discount that manufacturers of Medicare Part D brand name
drugs must provide to Medicare Part D beneficiaries during the coverage gap from 50% to 70%. There are a number of additional bills pending in Congress
that would affect drug pricing in the Medicare and Medicaid programs. Additional healthcare reform efforts have sought to address issues related to the
COVID-19 pandemic, including an expansion of telehealth coverage under Medicare and accelerated or advanced Medicare payments to healthcare providers.
Adoption of new healthcare reform legislation at the federal or state level could affect demand for, or pricing of, our products or product candidates if
approved for sale. We cannot, however, predict the ultimate content, timing or effect of any healthcare reform legislation or action, or its impact on us,
including increased compliance requirements and costs, all of which may adversely affect our future business, operations and financial results.

The increasing availability and use of innovative specialty pharmaceuticals for rare diseases, combined with their relative higher cost as compared to
other types of pharmaceutical products, is generating significant third-party payor interest in developing cost-containment strategies targeted to this sector.
Government regulations in both U.S. and ex-U.S. markets could further limit the prices that can be charged for our products and may limit our commercial
opportunity. The increasing use of cost-effectiveness assessments in markets around the world and the financial challenges faced by many governments may
lead to significant adverse effects on our business. Additionally, any legislation or regulatory changes or relaxation of laws that restrict imports of drugs from
other countries, revisions to reimbursement or pharmaceuticals under government programs or general budget control actions also could reduce the net price
we receive for our products.

31

We have experienced challenges commercializing products outside of the U.S., and our future revenues will be dependent on our ability to obtain adequate
reimbursement for our products.

In most ex-U.S. markets, the pricing and reimbursement of therapeutic and other pharmaceutical products is subject to governmental control. Given recent

global economic pressures, including due to the COVID-19 pandemic, and geopolitical uncertainty, government authorities throughout the world are
increasingly attempting to limit or regulate the price of drug products. The reimbursement process in ex-U.S. markets can take a significant time to conclude
and reimbursement decisions are made on a country-by-country basis.

Our medicines treat life-threatening conditions and address relatively small patient populations, and our research and development programs are primarily
focused on developing medicines to treat similar diseases. Particular attention is being paid by payors, including government and private payors, to these types
of high-cost medicines, and countries are increasingly refusing to reimburse costly medicines. We have experienced challenges in obtaining timely
reimbursement for our products in various countries outside the U.S. We continue to experience such challenges in some countries. For example, we obtained
reimbursement for ORKAMBI and SYMKEVI in England in the fourth quarter of 2019, four years after ORKAMBI’s initial approval in 2015. Our future
product revenues, including from TRIKAFTA/KAFTRIO, depend on, among other things, our ability to complete reimbursement discussions in ex-U.S.
markets for our products. There is no assurance that coverage and reimbursement will be available outside of the U.S. for our four approved medicines or any
future medicine, and, even if it is available, whether the timing or the level of reimbursement will be sufficient to allow us to market our medicines. Adverse
pricing limitations or a delay in obtaining coverage and reimbursement would decrease our future net product revenues and harm our business.

We have limited experience developing cell and genetic therapies and could experience challenges with these programs, which could result in delays or
prevent the development, manufacturing and commercialization of our cell and genetic therapies.

We are investing significant resources in the research, development and manufacturing of cell and genetic therapies. While we have previously

successfully developed, manufactured and commercialized several small molecule drugs, we have limited experience with the development, manufacture and
commercialization of cell and genetic therapies. Development, manufacturing and commercialization of cell and genetic therapies are subject to the same risks
and uncertainties as development, manufacturing and commercializing small molecules. In addition:

•

the manufacturing processes for cell and genetic therapies are different and more complex than the manufacturing processes required for small
molecule drugs, and require different systems, equipment, facilities and expertise to develop and maintain;

• we may encounter difficulties in the production of our cell and genetic therapies and ensuring that the product meets required specifications;

•

•

there have been a limited number of regulatory approvals for genetic therapies to date, the regulatory requirements governing genetic therapies
continue to evolve, and regulatory positions and interpretations can change or lead to delays or significant unexpected costs with respect to our
genetic therapy programs;

the commercial success of cell or genetic therapies, including CTX001, if approved, will depend in part on the medical community, patients, and
third-party or governmental payers accepting cell or genetic therapy products in general, and the applicable medicine as medically useful, cost-
effective, and safe; and

• market acceptance will be dependent in part on the prevalence and severity of side effects associated with the procedure by which the cell or genetic

therapy is administered, including, with respect to CTX001, if approved, the prevalence and severity of any side effects resulting from the
myeloablative preconditioning regimen.

For programs addressing rare genetic diseases with small patient populations, we may not be able to identify, recruit and enroll a sufficient number of
patients, or those with required or desired characteristics, to complete our clinical studies in an adequate and timely manner. Additionally, patients may be
unwilling to participate in our clinical trials because of concerns that cell and genetic therapies are unsafe or unethical, negative publicity from adverse events
in the biotechnology or gene therapy industries or for other reasons, including competitive clinical studies for similar patient populations.

32

In order to develop and commercialize any future cell or genetic therapies, we will need to incur substantial expenditures to develop, contract for, or
otherwise arrange for the necessary manufacturing capabilities. Additionally, the manufacture of cell and genetic therapies requires significant expertise. Even
with the relevant experience and expertise, manufacturers of cell and genetic therapy products often encounter difficulties in production, including difficulties
with production costs and yields, quality control, and compliance with federal, state and foreign regulations. We cannot make any assurances that these
problems will not occur, or that we will be able to resolve or address problems that occur in a timely manner, or at all.

To the extent we develop capabilities internally, there are many risks that could result in delays and additional costs, including the need to hire and train
qualified employees and obtain access to necessary equipment and third-party technology. To the extent we partner with third parties to manufacture our cell
or genetic therapies, any complexity in the manufacture of our products and product candidates may require lengthy technology transfers.

There also is significant uncertainty related to the insurance coverage and reimbursement of cell or genetic therapy products, including gene therapies that
are potential one-time treatments. It is difficult to predict what third party payors, including U.S. or ex-U.S. governments or private insurance companies, will
decide with respect to reimbursement for novel cell and genetic therapies like the ones in our pipeline. Additionally, reimbursement rates for cell and genetic
therapies approved before ours could create an adverse environment for reimbursement of any therapies we ultimately commercialize. The administration of
our products may require procedures for the collection of cells from patients, followed by other procedures either before or after delivery of the cell or genetic
therapy. The manner and level at which reimbursement is provided for these services also is important. An inadequate reimbursement for such services may
adversely affect physician decision to recommend any product for which we obtain approval in the future and our ability to market or sell them.

Given there are only a few approved cell and genetic therapy products, it also is difficult to determine how long it will take or reasonably estimate the
costs to develop, manufacture and commercialize cell or genetic therapies. In addition, our cell-based therapies include approaches involving devices, which
are subject to additional regulatory requirements. If we are unable to successfully develop, manufacture or commercialize such therapies on a timely or
profitable basis, or at all, we may not realize benefits or generate cash flows based on our investments in these programs and our business, financial condition,
results of operations and our stock price would likely be adversely affected.

We are dependent upon a small number of customers for a significant portion of our revenue, and the loss of, or significant reduction in sales to, these
customers would adversely affect our results of operations.

In the U.S., we sell our products principally to a limited number of specialty pharmacy and specialty distributors, which subsequently resell our products

to patients and health care providers. Internationally, we sell our products primarily to a limited number of specialty distributors and retail chains, as well as
hospitals and clinics. We expect this significant customer concentration to continue for the foreseeable future. Our ability to generate and grow sales of our CF
medicines will depend significantly on the extent to which these specialty distributors and specialty pharmacies are able to provide adequate distribution of
our products to patients and healthcare providers. The loss of any large customer, a significant reduction in sales we make to them, any cancellation of orders
they have made with us, or any failure to pay for the products we have shipped to them could adversely affect our business, financial condition and results of
operations.

Risks Related to Development and Clinical Testing of Our Products and Drug Candidates

Our drug candidates remain subject to clinical testing and regulatory approval. Our future success is dependent on our ability to successfully develop
additional drug candidates for both CF and non-CF indications.

Our business depends upon the successful development and commercialization of drug candidates. These drug candidates are in various stages of
development and must satisfy rigorous standards of safety and efficacy before they can be approved for sale by the FDA or comparable foreign regulatory
authorities. To satisfy these standards, we must allocate resources among our various development programs and must engage in expensive and lengthy testing
of our drug candidates. Discovery and development efforts for new pharmaceutical products, including new combination therapies, are resource-intensive and
may take 10 to 15 years or longer for each drug candidate. Despite our efforts, our drug candidates may not:

•    offer therapeutic or other improvement over existing competitive therapies;

•    show the level of safety and efficacy, including the level of statistical significance, required by the FDA or other regulatory authorities for approval of

a drug candidate;

33

•    meet applicable regulatory standards;

•    be capable of being produced in commercial quantities at acceptable costs; or

•    if approved for commercial sale, be successfully marketed as pharmaceutical products.

We have recently completed and/or have ongoing or planned clinical trials for several of our drug candidates. The strength of our product portfolio and

pipeline will depend in large part upon the outcomes of these clinical trials, including clinical trials evaluating our triple combination therapy in younger
children with CF and our clinical trials of potential medicines to treat other diseases. Results of our clinical trials and findings from our nonclinical studies,
including toxicology findings in nonclinical studies conducted concurrently with clinical trials, could lead to abrupt changes in our development activities,
including the possible cessation of development activities associated with a particular drug candidate or program. For example, in October 2020, we
discontinued development of VX-814, a drug candidate for the treatment of AAT, based on the safety and pharmacokinetic profile observed in the clinical
trial.

Moreover, clinical data are often susceptible to varying interpretations, and many companies that have believed their drug candidates performed
satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of their drug candidate. Furthermore, results from our clinical trials may
not meet the level of statistical significance or otherwise provide the level of evidence or safety and efficacy required by the FDA or other regulatory
authorities for approval of a drug candidate. Finally, clinical trials are expensive and require significant operational resources to implement and maintain.

Many companies in the pharmaceutical and biotechnology industries, including our company, have suffered significant setbacks in later-stage clinical
trials even after achieving promising results in earlier-stage clinical trials. For example, the results from completed preclinical studies and clinical trials may
not be replicated in later clinical trials, and ongoing clinical trials for our drug candidates may not be predictive of the results we may obtain in later-stage
clinical trials or of the likelihood of approval of a drug candidate for commercial sale. In addition, from time to time, we report interim data from our clinical
trials. Interim data from a clinical trial may not be predictive of final results from the clinical trial. Failure to advance drug candidates through clinical
development could impair our ability to ultimately commercialize products, which could materially harm our business and long-term prospects.

If we are unable to obtain regulatory approval, we will be unable to commercialize our drug candidates.

The time required to complete clinical trials and to satisfy the FDA and other countries’ regulatory review processes is uncertain and typically takes many
years. Our analysis of data obtained from nonclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could
delay, limit or prevent regulatory approval. We also may encounter unanticipated delays or increased costs due to government regulation from future
legislation or administrative action or changes in governmental policy during the period of drug development, clinical trials and governmental regulatory
review.

We may seek a Fast Track, Priority Review, Breakthrough Therapy, and/or RMAT designation for some of our drug candidates. Drug candidates that

receive one or more of these designations may be eligible for, among other things, a priority regulatory review. Each of these designations is within the
discretion of the FDA. Accordingly, even if we believe one of our drug candidates meets the criteria for Fast Track, Priority Review, Breakthrough Therapy
and/or RMAT designation, the FDA may disagree and instead determine not to make such designation. The receipt of one or more of these designations for a
drug candidate does not guarantee a faster development process, review or approval compared to drugs developed or considered for approval under
conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of our drugs or drug candidates qualifies for
Fast Track, Priority Review, Breakthrough Therapy and/or RMAT designation, the FDA may later decide to withdraw such designation if it determines that
the drug or drug candidate no longer meets the conditions for qualification.

Any failure to obtain regulatory approvals for a drug candidate would prevent us from commercializing that drug candidate. Any delay in obtaining
required regulatory approvals could materially adversely affect our ability to successfully commercialize a drug candidate. Furthermore, any regulatory
approval to market a drug may be subject to limitations that we do not expect on the indicated uses for which we may market the drug. Any such limitations
could reduce the size or demand of the market for the drug.

We also are subject to numerous foreign regulatory requirements governing the conduct of clinical trials, manufacturing and marketing authorization,

pricing and third-party reimbursement. Non-U.S. jurisdictions have different approval

34

procedures than those required by the FDA, and these jurisdictions may impose additional testing requirements for our drug candidates. The foreign regulatory
approval process includes all of the risks associated with the FDA approval process described above, as well as risks attributable to the satisfaction of foreign
requirements. Approval by the FDA does not ensure approval by regulatory authorities outside the U.S. and approval by a foreign regulatory authority does
not ensure approval by the FDA. In addition, although the FDA may accept data from clinical trials conducted outside the U.S., acceptance of this data is
subject to conditions imposed by the FDA. For example, the clinical trial must be well designed and conducted and performed by qualified investigators in
accordance with ethical principles. The trial population also must adequately represent the U.S. population, and the data must be applicable to the U.S.
population and U.S. medical practice in ways that the FDA deems clinically meaningful. In addition, while these clinical trials are subject to applicable local
laws, FDA acceptance of the data will depend on its determination that the trials also complied with all applicable U.S. laws and regulations. If the FDA does
not accept the data from any trial that we conduct outside the U.S., it would likely result in the need for additional trials, which would be costly and time-
consuming and delay or permanently halt our development of the applicable drug candidate.

If clinical trials are prolonged or delayed, our development timelines for the affected development program could be extended, our costs to develop the
drug candidate could increase and the competitive position of the drug candidate could be adversely affected.

We cannot predict whether or not we will encounter problems with any of our completed, ongoing or planned clinical trials that will cause us or
regulatory authorities to delay or suspend clinical trials, or delay the analysis of data from our completed or ongoing clinical trials. Among the factors that
could delay our development programs are:

•    ongoing discussions with the FDA or comparable foreign authorities regarding the scope or design of our clinical trials and the number of clinical

trials we must conduct;

•    delays in enrolling volunteers or patients into clinical trials, including as a result of low numbers of patients that meet the eligibility criteria for the

trial;

•    a lower than anticipated retention rate of volunteers or patients in clinical trials;

•    the need to repeat clinical trials as a result of inconclusive results, unforeseen complications in testing or clinical investigator error;

•    inadequate supply or deficient quality of drug candidate materials or other materials necessary for the conduct of our clinical trials;

•    unfavorable FDA or foreign regulatory authority inspection and review of a manufacturing facility that supplied clinical trial materials or its relevant

manufacturing records or a clinical trial site or records of any clinical or preclinical investigation;

•    unfavorable scientific results from clinical trials;

•    serious and unexpected drug-related side-effects experienced by participants in our clinical trials or by participants in clinical trials being conducted by

our competitors to evaluate drug candidates with similar mechanisms of action or structures to therapies that we are developing;

•    favorable results in testing of our competitors’ drug candidates, or FDA or foreign regulatory authority approval of our competitors’ drug candidates;

or

•    action by the FDA or a foreign regulatory authority to place a clinical hold or partial clinical hold on a trial or compound or deeming the clinical trial

conduct as problematic.

Our ability to enroll patients in our clinical trials in sufficient numbers and on a timely basis is subject to a number of factors, including the size of the
patient population, the nature of the protocol, the proximity of patients to clinical sites, the availability of effective treatments for the relevant disease, the
number of other clinical trials ongoing and competing for patients in the same indication, the eligibility criteria for the clinical trial, and the ongoing COVID-
19 pandemic. In addition, patients may drop out of our clinical trials or may be lost to follow-up medical evaluation after treatment ends, and this could impair
the validity or statistical significance of the trials. Clinical trials are expensive and require significant operational

35

resources. Delays in patient enrollment or unforeseen drop-out rates may result in increased costs and longer development times.

We, our collaborators, the FDA or other applicable regulatory authorities may suspend clinical trials of a drug candidate at any time if we or they believe
the healthy volunteers or patients participating in such clinical trials are being exposed to unacceptable health risks or for other reasons. Any such suspension
could materially adversely affect the development of a particular drug candidate and our business.

Risks Related to Government Regulation

If regulatory authorities interpret any of our conduct, including our marketing practices, as being in violation of applicable health care laws, including
fraud and abuse laws, laws prohibiting off-label promotion, disclosure laws or other similar laws, we may be subject to civil or criminal penalties.

We are subject to health care fraud and abuse laws, such as the federal False Claims Act and anti-kickback laws, which prohibit off-label product

promotion and other similar laws and regulations both in the U.S. and in non-U.S. markets.

The federal anti-kickback law prohibits knowingly and willfully offering, paying, soliciting, receiving or providing remuneration, directly or indirectly, in

exchange for or to induce either the referral of an individual, or the ordering, furnishing, arranging for or recommending of an item or service that is
reimbursable, in whole or in part, by a federal health care program, such as Medicare or Medicaid. Because of the broad scope of the prohibition, most
financial interactions between pharmaceutical manufacturers and prescribers, purchasers, third party payors and patients would be subject to the statute.
Although there are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution, the exceptions and
safe harbors are narrow. Financial interactions must therefore be structured carefully to qualify for protection or otherwise withstand scrutiny.

Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government,
or knowingly making, or causing to be made, a false statement to get a false claim paid. Pharmaceutical companies have been prosecuted under these laws for
a variety of alleged promotional and marketing activities, such as providing free product to customers with the expectation that the customers would bill
federal programs for the product; reporting to pricing services inflated average wholesale prices that were then used by federal programs to set reimbursement
rates; engaging in promotion for uses that the FDA has not approved, known as “off-label” uses, that caused claims to be submitted to Medicaid for those off-
label uses; submitting inflated “best price” information to the Medicaid Rebate Program; and certain manufacturing-related violations. The scope of this and
other laws may expand in ways that make compliance more difficult and expensive.

Although physicians are permitted, based on their medical judgment, to prescribe products for indications other than those approved by the FDA,
manufacturers are prohibited from promoting their products for such off-label uses. We market our products to eligible people with CF for whom the
applicable product has been approved and provide promotional materials and training programs to physicians regarding the use of each product in these
patient populations. These eligible people do not represent all people with CF. If the FDA determines that our promotional materials, training or other
activities constitute off-label promotion, it could request that we modify our training or promotional materials or other activities, conduct corrective
advertising or subject us to regulatory enforcement actions, including the issuance of a warning letter, injunction, seizure, civil fine and criminal penalties. It
also is possible that other federal, state or foreign enforcement authorities might take action if they believe that the alleged improper promotion led to the
submission and payment of claims for an off-label use, which could result in significant fines or penalties under other statutory authorities, such as laws
prohibiting false claims for reimbursement. Even if it is later determined we were not in violation of these laws, we may be faced with negative publicity,
incur significant expenses defending our actions and have to divert significant management resources from other matters.

In the U.S., federal and state laws regulate financial interactions between pharmaceutical manufacturers and healthcare providers, require disclosure to
government authorities and the public of such interactions, and mandate the adoption of compliance standards or programs. For example, the so-called federal
“sunshine law” requires pharmaceutical manufacturers to report annually to the Centers for Medicare & Medicaid Services, or CMS, payments or other
transfers of value made by that entity to physicians and teaching hospitals (and additional categories of health care practitioners beginning with reports
submitted on or after January 1, 2022). We also have similar reporting obligations with respect to financial interactions throughout the E.U. We expended
significant efforts to establish, and are continuing to devote significant resources to

36

maintain and enhance, systems and processes in order to comply with these regulations. Requirements to track and disclose financial interactions with health
care providers and organizations increase government and public scrutiny of these financial interactions. Failure to comply with the reporting requirements
could result in significant civil monetary penalties.

The sales and marketing practices of our industry have been the subject of increased scrutiny from government authorities in the U.S. and other countries

in which we market our products, and we believe that this trend will continue. Many of these laws have not been fully interpreted by the government
authorities or the courts, and their provisions are subject to a variety of interpretations. While we have a corporate compliance program which, together with
our policies and procedures, is designed to actively identify, prevent and mitigate risk through the implementation of compliance policies and systems and the
promotion of a culture of compliance, if we are found not to be in full compliance with these laws and regulations, our business could be materially harmed.
We may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from federal health care programs and/or the curtailment or
restructuring of our operations. Even if we successfully defend against government challenge, responding to the challenge may cause us to incur significant
legal expenses and divert our management’s attention from the operation of our business.

If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other governmental pricing programs in the
U.S., we could be subject to additional reimbursement requirements, penalties, sanctions and fines which could have a material adverse effect on our
business, financial condition, results of operations and growth prospects.

We participate in the Medicaid Drug Rebate Program, the 340B Drug Pricing Program, and a number of other federal and state government pricing
programs in the U.S. in order to obtain coverage for our products by certain government health care programs. These programs would generally require us to
pay rebates or provide discounts to certain private purchasers or government payers in connection with our products when dispensed to beneficiaries of these
programs. In some cases, such as with the Medicaid Drug Rebate Program, the rebates are based on pricing and rebate calculations that we report on a
monthly and quarterly basis to the government agencies that administer the programs. The terms, scope and complexity of these government pricing programs
change frequently. We may also have reimbursement obligations or be subject to penalties if we fail to provide timely and accurate information to the
government, pay the correct rebates or offer the correct discounted pricing. Changes to the price reporting or rebate requirements of these programs would
affect our obligations to pay rebates or offer discounts. CMS recently proposed changes to the Medicaid Drug Rebate calculations to address treatment of
value-based arrangements, accumulator adjustment programs implemented by payers, and new formulations of existing products. Responding to current and
future changes to these and other Medicaid Rebate requirements may increase our costs and the complexity of compliance, will be time-consuming, and could
have a material adverse effect on our results of operations.

If our processes and systems are not compliant with regulatory requirements, we could be subject to restrictions on marketing our products or could be
delayed in submitting regulatory filings seeking approvals for our drug candidates.

We have a number of regulated processes and systems that are required both prior to and following approval of our drugs and drug candidates. These

processes and systems are subject to continual review and periodic inspection by the FDA and other regulatory bodies. In addition, the clinical research
organizations and other third parties that we work with in our non-clinical studies and clinical trials and our oversight of such parties are subject to similar
reviews and periodic inspection by the FDA and other regulatory bodies. If compliance issues are identified at any point in the development and approval
process, we may experience delays in filing for regulatory approval for our drug candidates, or delays in obtaining regulatory approval after filing, if at all.
Any later discovery of previously unknown problems or safety issues with approved drugs or manufacturing processes, or failure to comply with regulatory
requirements, may result in restrictions on such drugs or manufacturing processes, withdrawal of drugs from the market, the imposition of civil or criminal
penalties or a refusal by the FDA and/or other regulatory bodies to approve pending applications for marketing approval of new drugs or supplements to
approved applications, any of which could have a material adverse effect on our business. In addition, we are party to agreements that transfer responsibility
for complying with specified regulatory requirements, such as filing and maintenance of marketing authorizations and safety reporting or compliance with
manufacturing requirements, to our collaborators and third-party manufacturers. If our collaborators or third-party manufacturers do not fulfill these regulatory
obligations, any drugs for which we or they obtain approval may be subject to later restrictions on manufacturing or sale, which could have a material adverse
effect on our business.

37

We are subject to various and evolving laws and regulations governing the privacy and security of personal data, and our failure to comply could adversely
affect our business, result in fines and/or criminal penalties, and damage our reputation.

We are subject to data privacy and security laws and regulations in various jurisdictions that apply to the collection, storage, use, sharing and security of

personal data, including health information, and impose significant compliance obligations. In addition, numerous other federal and state laws, including state
security breach notification laws, state health information privacy laws and federal and state consumer protection laws, govern the collection, use, disclosure
and security of personal information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an
increasing focus on privacy and data protection issues with the potential to affect our business.

For example, the E.U. General Data Protection Regulation, or GDPR, went into effect in 2018 and has imposed new obligations on us with respect to our

processing of personal data and the cross-border transfer of such data, including higher standards of obtaining consent, more robust transparency requirements,
data breach notification requirements, requirements for contractual language with our data processors, and stronger individual data rights. Different E.U.
member states have interpreted the GDPR differently and many have imposed additional requirements, which add to the complexity of processing personal
data in the E.U. The GDPR also imposes strict rules on the transfer of personal data to countries outside the E.U., including the U.S., and permits data
protection authorities to impose large penalties for violations of the GDPR. Compliance with the GDPR is a rigorous and time-intensive process that may
increase our cost of doing business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to fines and
penalties, litigation, and reputational harm in connection with any activities falling within the scope of the GDPR.

In the U.S., California has passed the California Consumer Privacy Act, which went into effect on January 1, 2020, and several states and the federal
government are actively considering proposed legislation governing the protection of personal data. Additionally, Brazil passed the General Data Protection
Law, or LGPD, which went into effect in August 2020. While we continue to address the implications of the new data privacy regulations, data privacy
remains an evolving landscape at both the domestic and international level, with new regulations coming into effect and continued legal challenges. Each law
is also subject to various interpretations by courts and regulatory agencies, creating even more uncertainty. While we have a global privacy program that
addresses such laws and regulations, our efforts to comply with the evolving data protection rules may be unsuccessful.

We must devote significant resources to understanding and complying with the changing landscape in this area. Failure to comply with data protection
laws may expose us to risk of enforcement actions taken by data protection authorities, private rights of action in some jurisdictions, and potential significant
penalties if we are found to be non-compliant. Failure to comply with the GDPR and applicable national data protection laws of European Economic Area
member states could lead to fines of up to €20,000,000 or up to 4% of the total worldwide annual revenue of the preceding financial year, whichever is higher.
Some of these laws and regulations also carry the possibility of criminal sanctions. For example, while we are not directly subject to the Health Insurance
Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act, or HIPAA, we could be
subject to penalties, including criminal penalties if we knowingly obtain or disclose individually identifiable health information from a HIPAA-covered health
care provider or research institution that has not complied with HIPAA’s requirements for disclosing such information. Furthermore, the number of
government investigations related to data security incidents and privacy violations continue to increase and government investigations typically require
significant resources and generate negative publicity, which could harm our business and our reputation.

The COVID-19 pandemic has added further complexity to the processing of personal data. For example, safety measures intended to protect our

employees, contractors, and other visitors to our sites may require the collection of certain personal data. Although we are focused on ensuring that personal
data is properly protected, our efforts may be unsuccessful and we could unintentionally be subject to unauthorized access or disclosure of such personal data.

Clinical Trial Regulation (EU) No. 536/2014, or the Clinical Trial Regulation, and the EMA policy on publication of clinical data for medicinal products

for human use both permit the EMA to publish clinical information submitted in MAAs. This provision of the Clinical Trial Regulation is expected to be
effective by the end of 2021. The ability of third parties to review and/or analyze data from our clinical trials may increase the risk of commercial
confidentiality breaches and result in enhanced scrutiny of our clinical trial results. Such scrutiny could result in public misconceptions regarding our drugs
and drug candidates. These publications could also result in the disclosure of information to our competitors that we might otherwise deem confidential, which
could harm our business.

38

If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our research and development efforts involve the regulated use of hazardous materials, chemicals and various controlled and radioactive compounds.

Although we believe that our safety procedures for handling and disposing of these materials comply with the standards prescribed by state, federal and
foreign regulations, the risk of loss of, or accidental contamination or injury from, these materials cannot be eliminated. If an accident occurs, we could be
held liable for resulting damages, which could be substantial. We also are subject to numerous environmental, health and workplace safety laws and
regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of biohazardous materials. Although we
maintain workers’ compensation insurance to cover us for costs we may incur due to injuries to our employees resulting from the use of these materials, this
insurance may not provide adequate coverage against potential liabilities. We maintain insurance to cover pollution conditions or other extraordinary or
unanticipated events relating to our use and disposal of hazardous materials that we believe is appropriate based on the small amount of hazardous materials
we generate. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to
comply with, and substantial fines or penalties if we violate, any of these laws or regulations.

Risks Related to Business Development Activities

Our ability to execute on our long-term strategy depends in part on our ability to engage in transactions and collaborations with other entities that add to
our pipeline or provide us with new commercial opportunities.

In order to achieve our long-term business objectives, we seek to license or acquire drugs, drug candidates and other technologies that have the potential
to complement our ongoing research and development efforts, access emerging technologies and license or acquire pipeline assets. These transactions may be
similar to prior transactions or may involve larger transactions or later-stage assets. We have faced and will continue to face significant competition for the
acquisition of rights to these types of drugs, drug candidates and other technologies from a variety of other companies, many of which have significantly more
financial resources and experience in business development activities than we have. In addition, non-profit organizations may be willing to provide capital to
the companies that control additional drugs, drug candidates or technologies, which may provide incentives for companies to advance these drugs, drug
candidates or technologies independently. Also, the cost of acquiring, in-licensing or otherwise obtaining rights to such drugs, drug candidates or other
technologies has grown dramatically in recent years and may be at levels that we cannot afford or that we believe are not justified by market potential. As a
result, we may not be able to acquire, in-license or otherwise obtain rights to additional drugs, drug candidates or other technologies on acceptable terms or at
all.

We may not realize the anticipated benefits of acquisitions of businesses or technologies, and the integration following any such acquisition may disrupt
our business and management.

It is challenging to effectively integrate businesses and technologies that we acquire, including the acquisitions of Semma and Exonics and the exclusive
licenses that we have acquired from CRISPR and Moderna, and we may not realize the benefits anticipated from such transactions. Achieving the anticipated
benefits of any transaction and successfully integrating acquired businesses or technologies involves a number of risks, including:

•    failure to successfully develop and commercialize the acquired drugs, drug candidates or technologies or to achieve other strategic objectives;

•    delays or inability to progress preclinical programs into clinical development or unfavorable data from clinical trials evaluating the acquired or

licensed drug or drug candidates;

•    difficulty in integrating the drugs, drug candidates, technologies, business operations and personnel of an acquired asset or company;

•    disruption of our ongoing business and distraction of our management and employees from daily operations or other opportunities and challenges;

•

the potential loss of key employees of an acquired company;

39

•    entry into markets in which we have no or limited direct prior experience or where competitors in such markets have stronger market positions;

•    potential failure of the due diligence processes to identify significant problems, liabilities or challenges of an acquired company, or acquired or

licensed drug, drug candidate or technology, including but not limited to, problems, liabilities or challenges with respect to intellectual property,
clinical or non-clinical data, safety, accounting practices, employee, or third-party relations and other known and unknown liabilities;

•    liability for activities of the acquired company or licensor before the acquisition or license, including intellectual property infringement claims,

violations of laws, commercial disputes, tax liabilities, and other known and unknown liabilities;

•    exposure to litigation or other claims in connection with, or inheritance of claims or litigation risk as a result of an acquisition or license, including but

not limited to, claims from terminated employees, customers, former equity holders or other third parties; and

•    difficulties in the integration of the acquired company’s departments, systems, including accounting, human resource and other administrative systems,
technologies, books and records, and procedures, as well as in maintaining uniform standards, controls, including internal control over financial
reporting required by the Sarbanes-Oxley Act of 2002 and related procedures and policies.

Acquisitions, licensing arrangements and other strategic transactions are inherently risky, and ultimately, if we do not complete an announced acquisition,
collaboration or strategic transaction or integrate an acquired or licensed asset, business or technology successfully and in a timely manner, we may not realize
the anticipated benefits of the strategic transaction.

We may later incur impairment charges related to assets acquired in any such transaction. For example, we entered into a strategic collaboration and
license agreement with Parion Sciences, Inc. to develop ENaC inhibitors in 2015 and incurred an impairment charge related to this collaboration in 2017.
Even if we achieve the long-term benefits associated with our strategic transactions, our expenses and short-term costs may increase materially and adversely
affect our liquidity and short-term net income. Future strategic transactions could result in potentially dilutive issuances of equity securities, the incurrence of
debt, the creation of contingent liabilities, impairment expenses related to goodwill, or impairment or amortization expenses related to other intangible assets,
all of which could harm our financial condition.

We face risks in connection with existing and future collaborations with respect to the development, manufacture and commercialization of our products
and drug candidates.

The risks that we face in connection with our current collaborations, including CRISPR, and any future collaborations, include the following:

•    Our collaborators may change the focus of their development and commercialization efforts or may have insufficient resources or expertise to

effectively develop, manufacture or commercialize our drug candidates.

•

The ability of some of our therapies to reach their potential could be limited if collaborators are unable to effectively develop, manufacture or
commercialize these therapies or drug candidates or decrease or fail to increase development or commercialization efforts related to those therapies or
drug candidates. Our collaboration agreements allocate development, manufacturing and commercialization responsibilities between us and our
collaborators and provide our collaborators with a level of discretion in determining the amount and timing of efforts and resources that they will
apply to these collaborations.

• Our collaborators may have limited experience in developing, manufacturing and commercializing therapies, either generally, or in the specific
therapeutic area. For example, CRISPR, which is responsible for leading commercialization of CTX001 in the U.S., has no prior experience
commercializing a therapy and is in the process of establishing the capabilities that would be required to commercialize CTX001 in the U.S.

•    Collaboration agreements may have the effect of limiting the areas of research and development that we may pursue, either alone or in collaboration

with third parties.

40

•    Collaborators may develop and commercialize, either alone or with others, drugs that are similar to or competitive with the drugs or drug candidates

that are the subject of their collaborations with us.

•    Disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of development,

might cause delays or termination of the research, development or commercialization of drug candidates, might lead to additional responsibilities or
costs for us with respect to drug candidates, or might result in litigation or arbitration. Any such disagreements would divert management attention
and resources and would be time-consuming and expensive.

•    Collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invite

litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation.

•    Collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability.

•    Investigations and/or compliance or enforcement actions against a collaborator, which may expose us to indirect liability as a result of our partnership

with such collaborator.

•    Our collaboration agreements are subject to termination under various circumstances.

Additionally, if a collaborator were to be involved in a business combination with a third party, it might de-emphasize or terminate the development or

commercialization of any drug candidate licensed to it by us. If one of our collaborators terminates its agreement with us, we may find it more difficult to
attract new collaborators and our perception in the business and financial communities could be harmed.

We may not be able to attract collaborators or external funding for the development and commercialization of certain of our drug candidates.

As part of our ongoing strategy, we may seek additional collaborative arrangements or external funding for certain of our development programs and/or

seek to expand existing collaborations to cover additional commercialization and/or development activities. We have a number of research programs and
clinical development programs, some of which are being developed in collaboration with a third party. For example, we are co-developing CTX001, an
investigational CRISPR/Cas9-based gene-editing therapy for SCD and TDT with our collaborator, CRISPR. At any time, we may determine that in order to
continue development of a drug candidate or program or successfully commercialize a drug we need to identify a collaborator or amend or expand an existing
collaboration. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s
resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those
factors may include the design or results of clinical trials, the likelihood of approval by the FDA, EMA or other regulatory authorities, the potential market for
the subject drug candidate, the costs and complexities of manufacturing and delivering such drug candidate to patients, the potential of competing products,
the existence of uncertainty with respect to our ownership of the applicable intellectual property, which can exist if there is a challenge to such ownership
without regard to the merits of the challenge, and industry and market conditions generally. Potentially, and depending on the circumstances, we may desire
that a collaborator either agree to fund portions of a drug development program led by us, or agree to provide all of the funding and directly lead the
development and commercialization of a program. No assurance can be given that any efforts we make to seek additional collaborative arrangements will be
successfully completed on a timely basis or at all. If we elect to fund and undertake development or commercialization activities on our own, we may need to
obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we are unable to enter into acceptable
collaborative relationships, one or more of our development programs could be delayed or terminated and the possibility of our receiving a return on our
investment in the program could be impaired.

41

Risks Related to Third-Party Manufacturing and Reliance on Third Parties

We depend on third-party manufacturers to manufacture our products and the materials we require for our clinical trials. We may not be able to maintain
these relationships and could experience supply disruptions outside of our control.

We rely on a worldwide network of third-party manufacturers to manufacture our drugs for commercial use and our drug candidates for clinical trials. As

a result of our reliance on these third-party manufacturers and suppliers, we could be subject to significant supply disruptions outside of our control. Our
supply chain for sourcing raw materials and manufacturing drug product ready for distribution is a multi-step international endeavor. Third-party contract
manufacturers, including some in China, perform different parts of our manufacturing process. Contract manufacturers may supply us with raw materials,
convert these raw materials into drug substance and/or convert the drug substance into final dosage form. Third parties are used for packaging, warehousing
and distribution of products. In cell and genetic therapies, third parties also will be used to both manufacture and deliver our therapies, which requires
significant expertise.

Establishing, managing and expanding this global supply chain requires a significant financial commitment and the creation and maintenance of
numerous third-party contractual relationships. Although we attempt to manage the business relationships with companies in our supply chain, we could be
subject to supply disruptions outside of our control. For example, we are collaborating with CRISPR on establishing the supply chain to support clinical trials
and commercial supply for CTX001, if approved. As a result, we do not have independent control over the related supply operations and are reliant on
CRISPR to adequately establish the corresponding supply chains.

Supply disruptions may result from a number of factors, including shortages in product raw materials, labor or technical difficulties, regulatory
inspections or restrictions, shipping or customs delays or any other performance failure by any third-party manufacturer on which we rely. Any supply
disruptions could disrupt sales of our products and/or the timing of our clinical trials.

We require a supply for our medicines for commercial sale and a supply of our drug candidates for use in our clinical trials. While we have developed
some internal capabilities, a majority of the manufacturing steps needed to produce our drug candidates and drug products are performed through a third-party
manufacturing network. To ensure the stability of our supply chains, we aim to develop additional sources of manufacture for all steps of our manufacturing
processes at the time of, or shortly after, marketing approval. Therefore, at any point in time, we may have a limited number of single source manufacturers
for certain steps in our manufacturing processes, particularly for recently launched products.

If we or our third-party manufacturers become unable or unwilling to continue manufacturing product and we are not able to promptly identify another

manufacturer, we could experience a disruption in the commercial supply of our then-marketed medicines, which would have a significant effect on patients,
our business and our product revenues. Similarly, a disruption in the clinical supply of drug products could delay the completion of clinical trials and affect
timelines for regulatory filings. There can be no assurance that we will be able to establish and maintain additional manufacturers for all of our drug
candidates and drug products on a timely basis or at all.

In the course of providing its services, a contract manufacturer may develop process technology related to the manufacture of our products or drug
candidates that the manufacturer owns, either independently or jointly with us. This would increase our reliance on that manufacturer or require us to obtain a
license from that manufacturer in order to have our products or drug candidates manufactured by other suppliers utilizing the same process.

We rely on third parties to conduct pre-clinical work, clinical trials and other activities, and those third parties may not perform satisfactorily, including
failing to meet established deadlines for the completion of such studies and/or trials or failing to satisfy regulatory requirements.

We rely on third parties such as contract research organizations to help manage certain pre-clinical work and our clinical trials and on medical institutions,
clinical investigators and clinical research organizations such as the Therapeutic Development Network, which is primarily funded by the CFF, to assist in the
design and review of, and to conduct our clinical trials, including enrolling qualified patients. In addition, we engage third party contractors to support
numerous other research, commercial and administrative activities. Our reliance on these third parties for clinical development activities reduces our control
over these activities but does not relieve us of our responsibilities. For example, we remain responsible for ensuring that each of our clinical trials is conducted
in accordance with the general investigational plan and protocols for the clinical trial. Moreover, the FDA requires us to comply with standards, commonly
referred to as good laboratory practices

42

and good clinical practices, for conducting, recording and reporting the results of pre-clinical and clinical trials to assure that data and reported results are
credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Such standards, particularly with respect to newer cell
and genetic therapies, will continue to evolve and subject us and third parties to new or changing requirements.

If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be required to replace them. Although we
believe that there are a number of other third-party contractors we could engage to continue the activities, it may result in a delay of the affected clinical trial,
drug development program or applicable activity. If clinical trials are not conducted in accordance with our contractual expectations or regulatory
requirements, action by regulatory authorities might significantly and adversely affect the conduct or progress of these clinical trials or in specific
circumstances might result in a requirement that a clinical trial be redone. Accordingly, our efforts to obtain regulatory approvals for and commercialize our
drug candidates could be delayed. In addition, failure of any third party contractor to conduct activities in accordance with our expectations could adversely
affect the relevant research, development, commercial or administrative activity.

Risks Related to Intellectual Property

If our patents do not protect our drugs or our drugs infringe third-party patents, we could be subject to litigation which could result in injunctions
preventing us from selling our products or substantial liabilities.

We have numerous issued patents and pending patent applications in the U.S., as well as counterparts in other countries. Our success will depend, in
significant part, on our ability to obtain and defend U.S. and foreign patents covering our drugs, their uses and our processes, to preserve our trade secrets and
to operate without infringing the proprietary rights of third parties. We cannot be certain that any patents will issue from our pending patent applications or,
even if patents issue or have issued, that the issued claims will provide us with adequate protection against competitive products or otherwise be commercially
valuable.

Due to evolving legal standards relating to the patentability, validity and enforceability of patents covering pharmaceutical inventions and the scope of

claims made under these patents, our ability to obtain, maintain and enforce patents is uncertain and involves complex legal and factual questions. Recent
patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of
our issued patents in the U.S. The Leahy-Smith America Invents Act, or the Leahy-Smith Act, includes a number of significant changes to U.S. patent law.
These include provisions that affect the way patent applications are prosecuted and may also affect patent litigation. The U.S. Patent Office developed new
regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-
Smith Act, and in particular, the first to file provisions, became effective in March 2013. The first to file provisions limit the rights of an inventor who is the
first to invent an invention but is not the first to file an application claiming that invention. U.S. and foreign patent applications typically are maintained in
confidence for a period of time after they initially are filed with the applicable patent office. Consequently, we cannot be certain that we were the first to
invent, or the first to file patent applications on, our products or drug candidates or their use. If a third party also has filed a U.S. patent application relating to
our drugs or drug candidates, their uses, or a similar invention, we may have to participate in legal or administrative proceedings to determine priority of
invention. For applications governed by the Leahy-Smith Act, if a third-party has an earlier filed U.S. patent application relating to our drugs or drug
candidates, their uses, or a similar invention, we may be unable to obtain an issued patent from our application.

The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability. Our patents may be challenged by third parties and
certain of our patents have been challenged in the past. This could result in the patent being deemed invalid, unenforceable or narrowed in scope, or the third
party may circumvent any such issued patents. Also, our pending patent applications may not issue, and we may not receive any additional patents.

Our patents or patents we license might not contain claims that are sufficiently broad to prevent others from developing competing products. For instance,

issued patents, or patents that may issue in the future, (i) relating to our small molecules may be limited to a particular molecule or molecules and may not
cover similar molecules that have similar clinical properties, and (ii) relating to cell or genetic therapies may not cover similar technologies that would allow
competitors to achieve similar results. Consequently, our competitors may independently develop competing products that do not infringe our patents or other
intellectual property. In addition, CRISPR only has non-exclusive or co-exclusive rights to the patent rights that protect the core CRISPR/Cas9 gene-editing
technology.

43

The laws of many foreign jurisdictions do not protect intellectual property rights to the same extent as in the U.S. and many companies in our segment of

the pharmaceutical industry have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such
difficulties in protecting or are otherwise precluded from effectively protecting our intellectual property rights in foreign jurisdictions, our business could be
substantially harmed.

Because of the extensive time required for the discovery, development, testing and regulatory review of drug candidates, it is possible that a patent may

expire before a drug candidate can be commercialized, or a patent may expire or remain in effect for only a short period following commercialization of such
drug candidate. This would result in a minimal or non-existent period of patent exclusivity. If our drug candidates are not commercialized significantly ahead
of the expiration date of any applicable patent, or if we have no patent protection on such drug candidates, then, to the extent available we would rely on other
forms of exclusivity, such as regulatory exclusivity provided by the FDCA and its counterpart agencies in various jurisdictions, and/or orphan drug
exclusivity.

Uncertainty over intellectual property in the pharmaceutical and biotechnology industry has been the source of litigation and other disputes, which is
inherently costly and unpredictable.

There is considerable uncertainty within our industry about the validity, scope and enforceability of many issued patents in the U.S. and elsewhere in the

world, and, to date, the law and practice remains in substantial flux both in the agencies that grant patents and in the courts. We cannot currently determine the
ultimate scope and validity of patents which may be granted to third parties in the future or which patents might be asserted as being infringed by the
manufacture, use and sale of our products.

There has been, and we expect that there may continue to be, significant litigation in the pharmaceutical industry regarding patents and other intellectual

property rights. Litigation, arbitrations, administrative proceedings and other legal actions with private parties and governmental authorities concerning
patents and other intellectual property rights may be protracted, expensive and distracting to management. Competitors may sue us as a way of delaying the
introduction of our drugs or to remove our drugs from the market. Any litigation, including litigation related to Abbreviated New Drug Applications, or
ANDA, litigation related to 505(b)(2) applications, interference proceedings to determine priority of inventions, derivations proceedings, inter partes review,
oppositions to patents in foreign countries, litigation against our collaborators or similar actions, may be costly and time consuming and could harm our
business. We expect that litigation may be necessary in some instances to determine the validity and scope of certain of our proprietary rights. Litigation may
be necessary in other instances to determine the validity, scope or non-infringement of certain patent rights claimed by third parties to be pertinent to the
manufacture, use or sale of our products. Ultimately, the outcome of such litigation could adversely affect the validity and scope of our patent or other
proprietary rights, hinder our ability to manufacture and market our products, or result in the assessment of significant monetary damages against us that may
exceed amounts, if any, accrued in our consolidated financial statements.

On July 24, 2020, we filed a lawsuit against Sun Pharmaceutical Industries Limited, or Sun, in the U.S. District Court for the District of Delaware

alleging infringement of U.S. Patent No. 10,646,481, or the ’481 patent. The lawsuit follows Vertex’s receipt of a Notice Letter on June 11, 2020, advising that
Sun had submitted an ANDA to the FDA seeking approval to manufacture and market a generic version of the 150 mg tablet of KALYDECO in the U.S. The
Notice Letter indicated that Sun submitted a “Paragraph IV” certification to the FDA in which Sun asserted that the ’481 patent is invalid or would not be
infringed by Sun’s generic product. The ’481 patent, which expires in 2029, was issued on May 12, 2020, and listed in the Orange Book with respect to
KALYDECO 150 mg tablets on June 1, 2020. Sun does not appear to challenge our other U.S. patents covering KALYDECO. Vertex intends to vigorously
enforce its intellectual property rights relating to KALYDECO, including the ’481 patent.

CRISPR has licensed certain rights to a worldwide patent portfolio that covers various aspects of the CRISPR/Cas9 editing platform technology
including, for example, compositions of matter and methods of use, including their use in targeting or cutting DNA from Dr. Charpentier, one of the named
inventors of this patent portfolio. The patent portfolio also has named inventors who assigned their rights either to the Regents of the University of California
or the University of Vienna, to whom we refer, together with Dr. Charpentier, as the CVC Group. For example, in connection with their collaboration,
Novartis and Intellia Therapeutics, Inc. have obtained a license to this patent portfolio in certain fields. Patents and patent applications in this patent portfolio
have been the subject of numerous contentious proceedings in the U.S., Europe, and other jurisdictions, including interference proceedings between the CVC
and the Broad Institute in the USPTO. Decisions rendered to date in these proceedings may be subject to appeal. To date, both the CVC and the Broad have
obtained granted patents that purport to cover aspects of CRISPR/Cas9 editing platform technology. The patents and patent

44

applications within the CVC patent portfolio and the Broad patent portfolio are, or may in the future be, involved in proceedings similar to interferences or
priority disputes in Europe or other foreign jurisdictions. We can give no assurances to the ultimate outcome of these proceedings or the dispute between the
CVC Group and Broad.

In addition to the Broad, other third parties have filed patent applications claiming CRISPR/Cas9-related inventions and may allege that they invented

one or more of the inventions claimed by the CVC Group. Thus, the USPTO may, in the future, declare an interference between certain CVC Group patent
applications and one or more patent applications. The Broad, as well as other third parties, could seek to assert its issued patents against us based on our
CRISPR/Cas9-based activities, including commercialization. Defense of these claims, regardless of their merit, could involve substantial litigation expense
and could result in a substantial diversion of management and other employee resources from our business. In the event of a successful claim of infringement
against us, we may have to pay substantial damages, obtain one or more licenses from third parties, pay royalties or redesign our infringing products, which
may be impossible or require substantial time and monetary expenditure. In that event, we could be unable to further develop and commercialize CTX001 or
other products that we may develop using the CRISPR/Cas9 technology we license from CRISPR.

To the extent that valid present or future third-party patents or other intellectual property rights cover our drugs, drug candidates or technologies, we or
our strategic collaborators may seek licenses or other agreements from the holders of such rights in order to avoid or settle legal claims. Such licenses may not
be available on acceptable terms, which may hinder our ability to, or prevent us from being able to, manufacture and market our drugs. Payments under any
licenses that we are able to obtain would reduce our profits derived from the covered products.

We may be subject to claims by third parties asserting that our employees or we have misappropriated their intellectual property, or claiming ownership of
what we regard as our own intellectual property.

Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or

potential competitors. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we
may be subject to claims that these employees or we have used or disclosed intellectual property, including trade secrets or other proprietary information, of
any such employee’s former employer. Litigation may be necessary to defend against these claims.

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property to execute

agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops
intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and we may be forced to
bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or

personnel. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to
management.

Risks associated with operating in foreign countries could materially adversely affect our business.

Risks Related To Our Operations

We have expanded our international operations over the past several years in order to market our CF medicines and expand our research and development

capabilities. New laws and industry codes in the E.U. and elsewhere have expanded transparency requirements regarding payments and transfers of value to
healthcare professionals, requirements surrounding patient-level clinical trial data, the protection of personal data and increased sanctions for violations.
Collectively, our expansion and these new requirements are adding to our compliance costs and potentially exposes us to sanctions in the event of an
infringement or failure to report in these jurisdictions. In addition, a significant portion of our commercial supply chain, including sourcing of raw materials
and manufacturing, is located in China and the E.U. Consequently, we are, and will continue to be, subject to risks related to operating in foreign countries,
including risks relating to intellectual property protections and business interruptions. These risks are increased with respect to countries such as China that
have substantially different local laws and business practices and weaker protections for intellectual property. Risks associated with operating a global
biotechnology company include:

•    differing regulatory requirements for drug approvals and regulation of approved drugs in foreign countries;

45

•    varying reimbursement regimes and difficulties or the inability to obtain reimbursement for our products in foreign countries in a timely manner;

•    differing patient treatment infrastructures, particularly since our business is focused on the treatment of serious diseases that affect relatively smaller

numbers of patients and are typically prescribed by specialist physicians;

•    collectability of accounts receivable;

•    changes in tariffs, trade barriers and regulatory requirements, the risks of which appear to have increased in the current political environment;

•    economic weakness, including recession and inflation, or political instability in particular foreign economies and markets;

•    differing levels of enforcement and/or recognition of contractual and intellectual property rights;

•    complying with local laws and regulations, which can change significantly over time;

•    foreign taxes, including withholding of payroll taxes;

•    foreign currency fluctuations, which could result in reduced revenues or increased operating expenses, and other obligations incident to doing business

or operating in another country;

•    workforce uncertainty in countries where labor unrest is more common than in the U.S.;

•    reliance on third-party vendors and suppliers;

•    import and export licensing requirements, tariffs, and other trade and travel restrictions;

•    global or regional public health emergencies that could affect our operations or business;

•    production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

•    business interruptions resulting from geo-political actions, including war and terrorism.

Our revenues are subject to foreign exchange rate fluctuations due to the global nature of our operations. Although we have foreign currency forward
contracts to hedge forecasted product revenues denominated in foreign currencies, our efforts to reduce currency exchange losses may not be successful. As a
result, currency fluctuations among our reporting currency, the U.S. dollar, and the currencies in which we do business will affect our operating results, often
in unpredictable ways.

In addition, our international operations are subject to regulation under U.S. law. For example, the FCPA prohibits U.S. companies and their

representatives from offering, promising, authorizing or making payments to foreign officials for the purpose of obtaining or retaining business abroad. In
many countries, the health care professionals we regularly interact with may meet the definition of a foreign government official for purposes of the FCPA. We
also are subject to import/export control laws. Failure to comply with domestic or foreign laws could result in various adverse consequences, including the
possible delay in approval or refusal to approve a product, recalls, seizures, withdrawal of an approved product from the market, the imposition of civil or
criminal sanctions, the prosecution of executives overseeing our international operations and corresponding bad publicity and negative perception of our
company in foreign countries.

We are subject to risks associated with the global COVID-19 pandemic.

The COVID-19 pandemic has broadly affected the global economy, resulted in significant travel and work restrictions in many regions and has put a
significant strain on healthcare resources. COVID-19 has had, and we expect it will continue to have, an impact on our operations, an impact on the operations
of our collaborators, third-party contractors and other entities, including governments, governmental agencies and payors, with which we interact, and an
impact on the people with CF who take our medicines. To date, the most significant effect on our business operations has been the requirement that a majority
of our employees work remotely. We have re-initiated enrollment and dosing in all of our ongoing clinical trials and initiated new clinical trials despite some
temporary pauses to enrollment and dosing early in the pandemic.

46

We continue to monitor local COVID-19 trends and government guidance for each of our site locations and are utilizing a phased, site-specific approach
to assess employee access to our sites. Currently, all of our research and manufacturing sites are open to essential employees. There can be no assurance that
our sites will remain open, when additional employees will gain access to our sites or whether we will be required to pause enrollment and dosing at clinical
trial sites. Any site closure or pause of a clinical trial could harm our operations and delay the development of our product candidates. In addition, even if sites
or clinical trials are open for enrollment, COVID-19 may nevertheless impact clinical trial enrollment or participation, for example due to suspension of in-
person procedures required for enrollment, government shut-down orders, or decreased patient willingness to participate compared to pre-COVID-19
pandemic levels. COVID-19 may also impact uptake of our medicines generally and patient retention in clinical trials, potentially resulting in higher drop-out
rates or missed visits, which may negatively affect the strength of our clinical trial data.

In the future, the economic impacts of the COVID-19 pandemic could affect our business directly or indirectly, including potentially affecting the net
prices for our products through changes in our payor mix as a result of increased unemployment in the U.S. or increased pressure on healthcare costs in the
U.S. and around the world. The effects on our research, development, manufacturing and commercialization activities, including the virtual launch of
KAFTRIO in the E.U., will be dependent on, among other things, the severity and duration of the COVID-19 pandemic and any worsening of the global
economic environment as a result thereof, as well as the impact of the pandemic on our third-party manufacturers, suppliers, distributors, subcontractors and
customers. While the ultimate impact of COVID-19 on our business is highly uncertain, any negative impacts that materialize could materially adversely
affect our operations, financial performance and stock price. Any negative impacts of COVID-19, alone or in combination with others, could exacerbate other
risk factors discussed herein. The full extent to which the COVID-19 pandemic will negatively affect our operations, financial performance and stock price
will depend on future developments that are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by
governmental authorities and other third parties in response to the pandemic.

If we fail to manage our operations effectively, our business may suffer.

We have expanded and are continuing to expand our global operations and capabilities, which has placed, and will continue to place, significant demands

on our management and our operational, research and development and financial infrastructure. To effectively manage our business, we need to:

•

•

•

•

•

implement and clearly communicate our corporate-wide strategies;

enhance our operational and financial infrastructure, including our controls over records and information;

enhance our operational, financial and management processes, including our cross-functional decision-making processes and our budget prioritization
systems;

train and manage our global employee base; and

enhance our compliance and legal resources.

If we fail to attract and retain skilled employees, our business could be materially harmed.

Due to the highly technical nature of our drug discovery and development activities, we require the services of highly qualified and trained scientists who
have the skills necessary to conduct these activities. In addition, we need to attract and retain employees with experience in marketing and commercialization
of medicines. We have entered into employment agreements with some executives and provide stock-related compensation benefits to all of our key
employees that vest over time and therefore induce them to remain with us. However, the employment agreements can be terminated by the executive on
relatively short notice. The value to employees of stock-related benefits that vest over time - such as restricted stock units and stock options - can be
significantly affected by movements in our stock price, and may, at any point in time, be insufficient to counteract more lucrative offers from other companies.
We face intense competition for our personnel from our competitors and other companies throughout our industry, especially with respect to employees with
expertise in cell or genetic therapies. We also experience competition for the hiring of scientific and clinical personnel from universities and research
institutions. Moreover, the growth of local biotechnology companies and the expansion of major pharmaceutical companies into the Boston area has increased
competition for the available pool of skilled employees, especially in technical fields. The high cost of living can make it difficult to attract employees from
other parts of the country to our Massachusetts headquarters. In addition, the available pool of skilled employees would be further reduced if immigration laws
change in a manner that increases restrictions on immigration. Our ability to continue to commercialize our products and achieve our

47

research and development objectives depends on our ability to respond effectively to these demands. If we are unable to hire and retain qualified personnel,
there could be a material adverse effect on our business.

Our business faces potential risks relating to the United Kingdom’s withdrawal from the European Union.

Our European headquarters and European research facility are located in the U.K., and a significant portion of our ex-U.S. net product revenues are

derived from sales in the U.K. On January 31, 2020, the U.K. formally withdrew from the E.U., also known as Brexit. The U.K. and the E.U. negotiated a
detailed post-Brexit Trade and Cooperating Agreement which went into effect on January 1, 2021. As of January 1, 2021, E.U. Treaties, E.U. free movement
rights and the general principals of E.U. law no longer apply in relation to the U.K. By virtue of the E.U. (Withdrawal) Act 2018, E.U. relations will continue
to apply in U.K. domestic law to the extent that they are not modified of revoked by regulations under that Act. Brexit could lead to legal uncertainty and
potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate. Given the lack of comparable precedent, it
is unclear what financial, trade, regulatory and legal implications the withdrawal of the U.K. from the E.U. would have and how such withdrawal would affect
us. Any of these effects of Brexit, among others, could adversely affect our business, financial condition and operating results.

Our business has a substantial risk of product liability claims and other litigation liability.

We are or may be involved in various legal proceedings, including securities/shareholder matters and claims related to product liability, intellectual
property and breach of contract. Such proceedings may involve claims for, or the possibility of, damages or fines and penalties involving substantial amounts
of money or other relief, including but not limited to civil or criminal fines and penalties. If any of these legal proceedings were to result in an adverse
outcome, it could have a material adverse effect on our business.

With respect to product liability and clinical trial risks, in the ordinary course of business we are subject to liability claims and lawsuits, including
potential class actions, alleging that our products or drug candidates have caused, or could cause, serious adverse events or other injury. We have product
liability insurance and clinical trial insurance in amounts that we believe are adequate to cover this risk. However, our insurance may not provide adequate
coverage against all potential liabilities. If a claim is brought against us, we might be required to pay legal and other expenses to defend the claim, as well as
pay uncovered damage awards resulting from a claim brought successfully against us and these damages could be significant and have a material adverse
effect on our financial condition. Furthermore, whether or not we are ultimately successful in defending any such claims, we might be required to direct
significant financial and managerial resources to such defense and adverse publicity is likely to result.

A breakdown or breach of our information technology systems could subject us to liability or interrupt the operation of our business.

We maintain and rely extensively on information technology systems and network infrastructures for the effective operation of our business. In the course

of our business, we collect, store and transmit confidential information (including personal information and intellectual property), and it is critical that we do
so in a secure manner to maintain the confidentiality and integrity of such confidential information. The size and complexity of our information technology
and information security systems makes such systems potentially vulnerable to service interruptions and to security breaches. A disruption, infiltration or
failure of our information technology systems or any of our data centers as a result of software or hardware malfunctions, computer viruses, cyber-attacks,
employee theft or misuse, power disruptions, natural disasters, floods or accidents could cause breaches of data security and loss of critical data, which in turn
could materially adversely affect our business and subject us to both private and governmental causes of action. While we have implemented security
measures in an attempt to minimize these risks to our data and information technology systems and have adopted a business continuity plan to deal with a
disruption to our information technology systems, cyber-attacks are increasing in their frequency, sophistication and intensity, and have become increasingly
difficult to detect. There can be no assurance that our efforts to protect our data and information systems will prevent breakdowns or breaches in our systems
that could adversely affect our business. In addition, our liability insurance may not be sufficient in type or amount to cover us against claims related to
security breaches, cyber-attacks or other related liabilities.

Risk of cyber-attack is increased with the majority of employees working remotely during the ongoing COVID-19 pandemic. During this time, there is an
increased risk that we may be vulnerable to cybersecurity-related events such as phishing attacks and other security threats as a result of our employees, third
party vendors and collaborators working remotely from non-corporate managed networks.

48

If our facilities were to experience a catastrophic loss, our operations would be seriously harmed.

Most of our operations, including our research and development activities, are conducted in a limited number of facilities. If any of our major facilities

were to experience a catastrophic loss, due to an earthquake, severe storms, fire or similar event, our operations could be seriously harmed. For example, our
corporate headquarters, as well as additional leased space that we use for certain logistical and laboratory operations and manufacturing, are located in a flood
zone along the Massachusetts coast. We have adopted a business continuity plan to address most crises. However, if we are unable to fully implement our
business continuity plans, we may experience delays in recovery of data and/or an inability to perform vital corporate functions, which could result in a
significant disruption in our research, development, manufacturing and/or commercial activities, large expenses to repair or replace the facility and/or the loss
of critical data, which could have a material adverse effect on our business.

The use of social media platforms presents risks and challenges.

Social media is being used by third parties to communicate about our products and drug candidates and the diseases our therapies are designed to treat.

We believe that members of the CF community may be more active on social media as compared to other patient populations due to the demographics of this
patient population. Social media practices in the pharmaceutical and biotechnology industries are evolving, which creates uncertainty and risk of
noncompliance with regulations applicable to our business. For example, patients may use social media platforms to comment on the effectiveness of, or
adverse experiences with, a drug or a drug candidate, which could result in reporting obligations. In addition, our employees may engage on social media in
ways that may not comply with legal or regulatory requirements, which may give rise to liability, lead to the loss of trade secrets and other intellectual
property, or result in public disclosure of protected personal information. There is a risk of inappropriate disclosure of sensitive information or negative or
inaccurate posts or comments about us on any social networking website. Certain data protection regulations, such as the GDPR, apply to personal data
contained on social media. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face
regulatory actions or incur harm to our business, including damage to our reputation.

Risks Related to Financial Results and Holding Our Common Stock

Our stock price may fluctuate.

Market prices for securities of companies such as ours are highly volatile. From January 1, 2020 to December 31, 2020, our common stock traded

between $197.47 and $306.08 per share. The market for our stock, like that of other companies in the biotechnology industry, has experienced significant price
and volume fluctuations. The future market price of our securities could be significantly and adversely affected by factors such as:

•    the information contained in our quarterly earnings releases, including our net product revenues and operating expenses for completed periods and

guidance regarding future periods;

•    announcements of FDA actions with respect to our therapies or those of our competitors, or regulatory filings for our therapies or those of our

competitors, or announcements of interim or final results of clinical trials or nonclinical studies relating to our therapies or those of our competitors;

•

•

developments in domestic and international governmental policy or regulation, for example, relating to drug pricing or intellectual property rights;

technological innovations or the introduction of new drugs by our competitors;

•    government regulatory action;

•    public concern as to the safety of drugs developed by us or our competitors;

•    developments in patent or other intellectual property rights or announcements relating to these matters;

•

information disclosed by third parties regarding our business or products;

•    developments relating specifically to other companies and market conditions for pharmaceutical and biotechnology stocks or stocks in general;

49

•    business development, capital structuring or financing activities; and

•    general worldwide or national economic, political and capital market conditions, including as a result of the ongoing COVID-19 pandemic.

Following periods of volatility in the market price of a company’s securities, stockholder derivative lawsuits and securities class action litigation are
common. Such litigation, if instituted against us or our officers and directors, could result in substantial costs and a diversion of management’s attention and
resources.

Our quarterly operating results are subject to significant fluctuation.

Our operating results have fluctuated from quarter to quarter in the past, and we expect that they will continue to do so in the future. Our revenues are
primarily dependent on the level of net product revenues from sales of our CF medicines. Our total net product revenues could vary on a quarterly basis based
on, among other factors, the timing of orders from our significant customers. Additional factors that have caused quarterly fluctuations to our operating results
in recent years include variable amounts of revenues, expenses related to business development activities, changes in the fair value of our strategic
investments, impairment charges, charges for excess and obsolete inventories, changes in the fair value of derivative instruments and the consolidation or
deconsolidation of variable interest entities. Our revenues also are subject to foreign exchange rate fluctuations due to the global nature of our operations.
Although we have foreign currency forward contracts to hedge forecasted product revenues denominated in foreign currencies, our efforts to reduce currency
exchange losses may not be successful. As a result, currency fluctuations among our reporting currency, the U.S. dollar, and the currencies in which we do
business may affect our operating results, often in unpredictable ways. Our quarterly results also could be materially affected by significant charges, which
may or may not be similar to charges we have experienced in the past. Most of our operating expenses relate to our research and development activities, do not
vary directly with the amount of revenues and are difficult to adjust in the short term. As a result, if revenues in a particular quarter are below expectations, we
are unlikely to reduce operating expenses proportionately for that quarter. These examples are only illustrative and other risks, including those discussed in
these “Risk Factors,” could also cause fluctuations in our reported financial results. Our operating results during any one period do not necessarily suggest the
results of future periods.

We expect that results from our clinical development activities and the clinical development activities of our competitors will continue to be released
periodically, and may result in significant volatility in the price of our common stock.

Any new information regarding our products and drug candidates or competitive products or potentially competitive drug candidates can substantially

affect investors’ perceptions regarding our future prospects. We, our collaborators and our competitors periodically provide updates regarding drug
development programs, typically through press releases, conference calls and presentations at medical conferences. These periodic updates often include
interim or final results from clinical trials conducted by us or our competitors and/or information about our or our competitors’ expectations regarding
regulatory filings and submissions as well as future clinical development of our products or drug candidates, competitive products or potentially competitive
drug candidates. The timing of the release of information by us regarding our drug development programs is often beyond our control and is influenced by the
timing of receipt of data from our clinical trials and by the general preference among pharmaceutical companies to disclose clinical data during medical
conferences. In addition, the information disclosed about our clinical trials, or our competitors’ clinical trials, may be based on interim rather than final data
that may involve interpretation difficulties and may in any event not accurately predict final results. The release of such information may result in volatility in
the price of our common stock.

Changes in tax laws, regulations and treaties could affect our future taxable income.

We are subject to taxation in numerous countries, states and other jurisdictions. As a result, our effective tax rate is derived from a combination of

applicable tax rates in the various places that we operate globally. Our effective tax rate may be different than experienced in the past due to numerous factors,
including changes in the mix of our profitability from country to country, the results of tax authority examinations/audits of our tax filings, adjustments to the
value of our uncertain tax positions, changes in accounting for income taxes and changes in tax laws or modifications of treaties in various jurisdictions. For
example, changes to the U.S. tax code are anticipated under the new administration. Any of these factors could cause us to experience an effective tax rate that
is significantly different from previous periods or our current expectations.

50

We continue to assess the impact of various tax reform proposals and modifications to existing tax treaties in all jurisdictions where we have operations to

determine the potential effect on our business and any assumptions we have made about our future taxable income. We cannot predict whether any specific
proposals will be enacted, the terms of any such proposals or what effect, if any, such proposals would have on our business if they were to be enacted.

Recommendations from the Organization for Economic Co-operation and Development that are part of the base erosion and profit shifting, or BEPS,
framework could result in changes in tax laws in countries where we do business and adversely affect our provision for income taxes and our current rate. If
these recommendations (or other changes in law) were adopted by the countries in which we do business, it could adversely affect our provision for income
tax and our current rate.

We may need to raise additional capital that may not be available.

General Risk Factors

We may need to raise additional capital in the future. Any potential public offering, private placement or debt financing may or may not be similar to the

transactions that we entered into in the past. Any debt financing may be on terms that, among other things, include conversion features that could result in
dilution to our then-existing security holders and restrict our ability to pay interest and dividends—although we do not intend to pay dividends for the
foreseeable future. Any equity financings would result in dilution to our then-existing security holders. If adequate funds are not available on acceptable terms,
or at all, we may be required to curtail significantly or discontinue one or more of our research, drug discovery or development programs, including clinical
trials, incur significant cash exit costs, or attempt to obtain funds through arrangements with collaborators or others that may require us to relinquish rights to
certain of our technologies, drugs or drug candidates. Based on many factors, including general economic conditions, additional financing may not be
available on acceptable terms, if at all.

Future indebtedness could materially and adversely affect our financial condition, and the terms of our credit agreements impose restrictions on our
business, reducing our operational flexibility and creating default risks.

In 2019, we entered into a credit agreement providing for a $500 million revolving facility. In September 2020, we entered into a second credit agreement
providing for a $2.0 billion revolving facility. Each of the credit agreements provides that, subject to the satisfaction of certain conditions, we may request the
borrowing capacity be increased by an additional $500.0 million. If we borrow under our current credit agreements or any future credit agreement, such
indebtedness could have important consequences to our business, including increasing our vulnerability to general adverse financial, business, economic and
industry conditions, as well as other factors that are beyond our control. The credit agreements require that we comply with certain financial covenants,
including (i) a consolidated leverage ratio covenant and (ii) a consolidated interest coverage ratio covenant, in each case to be measured on a quarterly basis.
Further, the credit agreements include negative covenants, subject to exceptions, restricting or limiting our ability and the ability of our subsidiaries to, among
other things, incur additional indebtedness, grant liens, engage in certain investment, acquisition and disposition transactions, pay dividends, repurchase
capital stock and enter into transactions with affiliates. As a result, we may be restricted from engaging in business activities that may otherwise improve our
business. Failure to comply with the covenants could result in an event of default that could trigger acceleration of our indebtedness, which would require us
to repay all amounts owing under the credit agreements and/or our finance leases and could have a material adverse effect on our business. Additionally, our
obligations under the credit agreements are unconditionally guaranteed by certain of our domestic subsidiaries.

Issuances of additional shares of our common stock could cause the price of our common stock to decline.

As of December 31, 2020, we had 259.9 million shares of common stock issued and outstanding. As of December 31, 2020, we also had outstanding
options to purchase 4.2 million shares of common stock with a weighted-average exercise price of $140.47 per share. Outstanding vested options are likely to
be exercised if the market price of our common stock exceeds the applicable exercise price, and, in the future, we expect to issue additional equity awards to
directors and employees. In addition, we may issue additional common stock or restricted securities in the future as part of financing activities or business
development activities and any such issuances may have a dilutive effect on our then-existing shareholders. Sales of substantial amounts of our common stock
in the open market, or the availability of such shares for sale, could adversely affect the price of our common stock. The issuance of restricted common stock
or common stock upon exercise of any outstanding options would be dilutive, and may cause the market price for a share of our common stock to decline.

51

There can be no assurance that we will repurchase shares of common stock or that we will repurchase shares at favorable prices.

In November 2020, our Board of Directors authorized a share repurchase program pursuant to which we are authorized to repurchase up to $500
million of our common stock by December 31, 2022. As of December 31, 2020, we had repurchased $75.1 million of common stock under the share
repurchase program and had remaining available $424.9 million to repurchase additional shares pursuant to this program.

Our stock repurchases will depend upon, among other factors, our cash balances and potential future capital requirements, results of operations, financial

condition and other factors that we may deem relevant. We can provide no assurance that we will repurchase stock at favorable prices, if at all.

We have adopted anti-takeover provisions and are subject to Massachusetts corporate laws that may frustrate any attempt to remove or replace our current
management or effectuate a business combination involving Vertex.

Our corporate charter and by-law provisions and Massachusetts state laws may discourage certain types of transactions involving an actual or potential

change of control of Vertex that might be beneficial to us or our security holders. Our by-laws grant the directors a right to adjourn annual meetings of
shareholders, and certain provisions of our by-laws may be amended only with an 80% shareholder vote. We may issue shares of any class or series of
preferred stock in the future without shareholder approval and upon such terms as our Board of Directors may determine. The rights of the holders of common
stock will be subject to, and may be adversely affected by, the rights of the holders of any class or series of preferred stock that may be issued in the future.
Massachusetts state law prohibits us from engaging in specified business combinations, unless the combination is approved or consummated in a prescribed
manner, and prohibits voting by any shareholder who acquires 20% or more of our voting stock without shareholder approval. As a result, shareholders or
other parties may find it more difficult to remove or replace our current management.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

We invest in scientific innovation to create transformative medicines for people with serious diseases with a focus on specialty markets. We have four
approved medicines to treat cystic fibrosis, or CF, a life-threatening genetic disease, and we are focused on increasing the number of patients eligible and able
to receive our current medicines through label expansions, approval of new medicines and expanded reimbursement. We are broadening our pipeline into
additional disease areas through internal research efforts and accessing external innovation through business development transactions.

Our triple combination regimen, TRIKAFTA/KAFTRIO, was approved in 2019 in the United States, or U.S., and in 2020 in the European Union, or E.U.

Collectively, our four medicines are approved to treat the majority of the approximately 83,000 people with CF in North America, Europe and Australia. We
are evaluating our medicines, including our triple combination regimen, in additional patient populations, including younger children, with the goal of having
small molecule treatments for up to 90% of people with CF. We are also pursuing genetic therapies to address the remaining 10% of people with CF.

Beyond CF, our small molecule programs include programs focused on developing treatments for alpha-1 antitrypsin, or AAT, deficiency, APOL1-
mediated kidney diseases and pain. We are also focused on developing cell and genetic therapies for various diseases in our pipeline. We are evaluating
CTX001, a genetic therapy, as a potential treatment for sickle cell disease, or SCD, and transfusion-dependent beta thalassemia, or TDT, in Phase 1/2 clinical
trials in collaboration with CRISPR Therapeutics AG, or CRISPR. In T1D, we are pursuing two programs for the transplant of functional islets into patients:
transplantation of islet cells alone, using immunosuppression to protect the implanted cells, and implantation of the islet cells inside a novel immunoprotective
device. In 2020, we continued to advance our cell and genetic therapy pipeline programs through internal research efforts and investing in business
development transactions to access emerging technologies.

Financial Highlights

Revenues

Expenses

In 2020, our net product revenues continued to increase due to the
approval of TRIKAFTA in late 2019 and uptake of our medicines in ex-
U.S. markets following the approval of KAFTRIO and completion of
several significant reimbursement agreements.

Our total R&D and SG&A expenses increased from $2.41 billion in 2019
to $2.60 billion in 2020. In 2020, cost of sales was approximately 12% of
our net product revenues.

58

Business Updates

Cystic Fibrosis

We expect to continue to grow our CF business through increasing the number of people with CF eligible and able to receive our medicines and providing

improved treatment options for people who are already eligible for one of our medicines. Since the beginning of 2020, we have made important progress in
activities supporting these efforts.

In August, the European Commission granted marketing authorization for KAFTRIO to treat people with CF 12 years of age and older with one
F508del mutation and one minimal function mutation, or two F508del mutations.

The FDA expanded the eligibility for TRIKAFTA to include people with CF 12 years of age and older with certain mutations that are responsive to
TRIKAFTA based on in vitro data. SYMDEKO and KALYDECO also received approvals to include additional responsive mutations in people with
CF 6 years of age and older and 4 months of age and older, respectively.

In January 2021, the FDA accepted our supplemental New Drug Application, or sNDA, for TRIKAFTA for the treatment of children with CF 6 to 11
years of age with at least one F508del mutation or have certain mutations that are responsive to TRIKAFTA based on in vitro data. The FDA granted
Priority Review of the sNDA.

The European Commission approved the label extension of SYMKEVI in combination with KALYDECO for the treatment of children with CF 6
years of age and older with two F508del mutations or one F508del mutation and certain residual function mutations.

The FDA approved KALYDECO for treatment of infants with CF four months of age and older who have at least one mutation in their CFTR gene
that is responsive to KALYDECO.

The European Commission approved KALYDECO for treatment of infants with CF four months of age and older who have the R117H mutation or
certain gating mutations.

Pipeline

We continue to advance a broad pipeline of potentially transformative small molecule, cell and genetic therapies aimed at treating serious diseases. Since

the beginning of 2020, we have made important progress in activities supporting these efforts.

Beta Thalassemia and Sickle Cell Disease

•

In December, we and our collaborator, CRISPR, announced positive interim data from 10 people with TDT or SCD treated with CTX001 and that 20
people with severe hemoglobinopathies have been dosed with CTX001 in the ongoing Phase 1/2 clinical trials. Enrollment and dosing are ongoing,
and completion of enrollment in both clinical trials is expected in 2021.

Alpha-1 Antitrypsin Deficiency

•

Enrollment is ongoing in a Phase 2 proof-of-concept clinical trial for the corrector VX-864. We expect data from this clinical trial in the first half of
2021.

• We discontinued development of VX-814, our first corrector, based on the safety and pharmacokinetic profile of VX-814 observed in a Phase 2

clinical trial.

APOL1-Mediated Kidney Diseases

•

Enrollment is ongoing in a Phase 2 proof-of-concept clinical trial designed to evaluate the reduction of proteinuria in people with APOL1-mediated
FSGS after treatment with VX-147. We expect data from this clinical trial in 2021.

Type 1 Diabetes

• We are developing a cell therapy designed to replace insulin-producing islet cells in patients with T1D. We are pursuing two programs for the

transplant of these functional islets into patients: transplantation of islet cells alone,

59

using immunosuppression to protect the implanted cells, and implantation of the islet cells inside a novel immunoprotective device.

•

In January 2021, the FDA cleared our IND for VX-880, the islet cells alone program. We expect to initiate a Phase 1/2 clinical trial evaluating this
program in the first half of 2021. This clinical trial will involve an infusion of fully differentiated, functional islet cells, and chronic administration of
concomitant immunosuppressive therapy, to protect the islet cells from immune rejection.

Investment in External Innovation

• We entered into a collaboration with Skyhawk Therapeutics, Inc., or Skyhawk, for the discovery and development of novel small molecules that

modulate RNA splicing for the treatment of serious diseases.

• We entered into a new collaboration with Moderna, Inc., or Moderna, aimed at the discovery and development of lipid nanoparticles and mRNAs that

can deliver gene-editing therapies to lung cells for the treatment of CF.

• We entered into a collaboration with Affinia Therapeutics, Inc., or Affinia, to gain access to a novel library of AAV capsids to support on our ongoing

research and development efforts in genetic therapies, including DMD, DM1 and CF.

COVID-19

We continue to monitor the impacts of the COVID-19 global pandemic on our business. COVID-19 has not affected our supply chain or the demand for

our medicines, and we believe that we will be able to continue to supply all of our approved medicines to patients globally. We have adjusted our business
operations in response to COVID-19, with a majority of our employees continuing to work remotely. We continue to monitor local COVID-19 trends and
government guidance for each of our site locations, and are utilizing a phased, site-specific approach to assess employee access to our sites. Currently, all of
our research and manufacturing sites are open to essential employees. To provide a safe working environment for our on-site employees, we have, among
other things, limited employee numbers at our open sites and increased safety measures, including at home and on-site testing in the U.S., enhanced cleaning
and sanitation protocols, required use of personal protective equipment for all on-site employees, hand sanitation stations throughout our open sites and
implementation of various social distancing measures while on-site.

Research

We continue to invest in our research programs and foster scientific innovation in order to identify and develop transformative medicines. Our strategy is

to combine transformative advances in the understanding of human disease and the science of therapeutics in order to identify and develop new medicines. We
believe that pursuing innovative approaches to treat diverse diseases of great unmet need allows us to balance the risks inherent in drug development and may
provide drug candidates that will form our pipeline in future years. To supplement our internal research programs, we acquire technologies and programs and
collaborate with biopharmaceutical and technology companies, leading academic research institutions, government laboratories, foundations and other
organizations, as needed, to advance research in our areas of therapeutic interest and to access technologies needed to execute on our strategy.

Drug Discovery and Development

Discovery and development of a new pharmaceutical product is a difficult and lengthy process that requires significant financial resources along with

extensive technical and regulatory expertise. Potential drug candidates are subjected to rigorous evaluations, driven in part by stringent regulatory
considerations, designed to generate information concerning efficacy, side effects, proper dosage levels and a variety of other physical and chemical
characteristics that are important in determining whether a drug candidate should be approved for marketing as a pharmaceutical product. Most chemical
compounds that are investigated as potential drug candidates never progress into development, and most drug candidates that do advance into development
never receive marketing approval. Because our investments in drug candidates are subject to considerable risks, we closely monitor the results of our
discovery, research, clinical trials and nonclinical studies and frequently evaluate our drug development programs in light of new data and scientific, business
and commercial insights, with the objective of balancing risk and potential. This process can result in rapid changes in focus and priorities as new information
becomes available and as we gain additional understanding of our ongoing programs and potential new programs, as well as those of our competitors. For
example, in October 2020, we discontinued development of VX-814, a

60

drug candidate for the treatment of AAT, based on the safety and pharmacokinetic profile of VX-814 observed in a Phase 2 clinical trial.

If we believe that data from a completed registration program support approval of a drug candidate, we submit an NDA or BLA to the FDA requesting
approval to market the drug candidate in the U.S. and seek analogous approvals from comparable regulatory authorities in jurisdictions outside the U.S. To
obtain approval, we must, among other things, demonstrate with evidence gathered in nonclinical studies and well-controlled clinical trials that the drug
candidate is safe and effective for the disease it is intended to treat and that the manufacturing facilities, processes and controls for the manufacture of the drug
candidate are adequate. The FDA and ex-U.S. regulatory authorities have substantial discretion in deciding whether or not a drug candidate should be granted
approval based on the benefits and risks of the drug candidate in the treatment of a particular disease, and could delay, limit or deny regulatory approval. If
regulatory delays are significant or regulatory approval is limited or denied altogether, our financial results and the commercial prospects for the drug
candidate involved will be harmed.

Regulatory Compliance

Our marketing of pharmaceutical products is subject to extensive and complex laws and regulations. We have a corporate compliance program designed

to actively identify, prevent and mitigate risk through the implementation of compliance policies and systems and through the promotion of a culture of
compliance. Among other laws, regulations and standards, we are subject to various U.S. federal and state laws, and comparable laws in other jurisdictions,
pertaining to health care fraud and abuse, including anti-kickback and false claims laws, and laws prohibiting the promotion of drugs for unapproved or off-
label uses. Anti-kickback laws generally make it illegal for a prescription drug manufacturer to knowingly and willfully solicit, offer, receive or pay any
remuneration in return for or to induce the referral of business, including the purchase or prescription of a particular drug that is reimbursed by a state or
federal health care program. False claims laws prohibit anyone from knowingly or willfully presenting for payment to third-party payors, including Medicare
and Medicaid, claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for
medically unnecessary items or services. We are subject to laws and regulations that regulate the sales and marketing practices of pharmaceutical
manufacturers, as well as laws such as the U.S. Foreign Corrupt Practices Act, which govern our international business practices with respect to payments to
government officials. In addition, we are subject to various data protection and privacy laws and regulations in the U.S., E.U., U.K., Canada, Australia and
other jurisdictions. We expect to continue to devote substantial resources to maintain, administer and expand these compliance programs globally.

Reimbursement

Sales of our products depend, to a large degree, on the extent to which our products are reimbursed by third-party payors, such as government health
programs, commercial insurance and managed health care organizations. We dedicate substantial management and other resources in order to obtain and
maintain appropriate levels of reimbursement for our products from third-party payors, including governmental organizations in the U.S. and ex-U.S. markets.

In the U.S., we have worked successfully with third party payors in order to promptly obtain appropriate levels of reimbursement for our CF medicines.

We plan to continue to engage in discussions with numerous commercial insurers and managed health care organizations, along with government health
programs that are typically managed by authorities in the individual states, to ensure that payors recognize the significant benefits that our medicines provide
by treating the underlying cause of CF and continue to provide access to our medicines.

In Europe and other ex-U.S. markets, we seek government reimbursement for our medicines on a country-by-country basis. This is necessary for each
new medicine, as well as label expansions for our current medicines. We successfully obtained reimbursement for KALYDECO in each significant ex-U.S.
market within two years of approval, but experienced significant challenges in obtaining reimbursement for ORKAMBI in certain ex-U.S. markets. With the
completion of reimbursement discussions in England and France in 2019, we have reimbursement for ORKAMBI or SYMKEVI in most of our significant ex-
U.S. markets. In addition, in several ex-U.S. markets, including England, Ireland, Denmark and Australia, our reimbursement agreements include innovative
arrangements that provide a pathway to access and rapid reimbursement for certain future CF medicines. For example, our existing reimbursement agreements
in England, Ireland, and Denmark have been expanded to include KAFTRIO. We expect to continue to focus significant resources to obtain appropriate
reimbursement for our products in ex-U.S. markets.

61

Strategic Transactions

Acquisitions

As part of our business strategy, we seek to acquire drugs, drug candidates and other technologies and businesses that have the potential to complement

our ongoing research and development efforts. In 2019, we invested significantly in business development transactions designed to augment our pipeline,
including the acquisition of Semma Therapeutics, Inc., or Semma, a privately-held company focused on the use of stem cell-derived human islets as a
potentially curative treatment for T1D, and Exonics Therapeutics, Inc., or Exonics, a privately-held company focused on creating transformative gene-editing
therapies to repair mutations that cause DMD and other severe neuromuscular diseases, including DM1. In the Semma acquisition, we paid approximately
$950.0 million in cash to Semma equity holders. In the Exonics acquisition, we paid approximately $245.0 million upfront to Exonics equity holders and
agreed to additional payments based upon successful achievement of specified development and regulatory milestones. We expect to continue to identify and
evaluate potential acquisitions and may include larger transactions or later stage assets.

Both of our 2019 acquisitions were accounted for as business combinations. As of the acquisition date for each transaction, the cash payments, as well as
the fair value of contingent consideration for Exonics, were allocated primarily to goodwill and the fair value of several in-process research and development
assets that we acquired. The fair value of contingent consideration related to Exonics was recorded as a liability and continues to be adjusted on a quarterly
basis. As a result, these acquisitions are primarily reflected in additional assets and liabilities on our consolidated balance sheet. Operating expenses incurred
by Exonics and Semma after the acquisition dates and specific expenses associated with the acquisitions are reflected in our consolidated statement of
operations.

Please refer to our critical accounting policies, “Acquisitions,” for further information regarding the significant judgments and estimates related to our

acquisitions.

Collaboration and Licensing Arrangements

We enter into arrangements with third parties, including collaboration and licensing arrangements, for the development, manufacture and

commercialization of drugs, drug candidates and other technologies that have the potential to complement our ongoing research and development efforts. We
expect to continue to identify and evaluate collaboration and licensing opportunities that may be similar to or different from the collaborations and licenses
that we have engaged in previously.

In-License Agreements

We have entered into collaborations with biotechnology and pharmaceutical companies in order to acquire rights or to license drug candidates or

technologies that enhance our pipeline and/or our research capabilities. Over the last several years, we entered into collaboration agreements with a number of
companies, including Affinia, Arbor Biotechnologies, Inc., CRISPR, Kymera Therapeutics, Inc., Moderna, Molecular Templates, Inc. and Skyhawk.
Generally, when we in-license a technology or drug candidate, we make upfront payments to the collaborator, assume the costs of the program and/or agree to
make contingent payments, which could consist of milestone, royalty and option payments. Most of these collaboration payments are expensed as research
and development expenses; however, depending on many factors, including the structure of the collaboration, the significance of the in-licensed drug
candidate to the collaborator’s operations and the other activities in which our collaborators are engaged, the accounting for these transactions can vary
significantly. Our research and development expenses included $184.6 million in 2020, $318.3 million in 2019 and $111.9 million in 2018 related to upfront
and milestone payments pursuant to our collaboration agreements.

Out-License Agreements

We also have out-licensed internally-developed programs to collaborators who are leading the development of these programs. These out-license

arrangements include our agreement with Merck KGaA, Darmstadt, Germany, which licensed oncology research and development programs from us in early
2017. Pursuant to these out-licensing arrangements, our collaborators are responsible for the research, development and commercialization costs associated
with these programs, and we are entitled to receive contingent milestone and/or royalty payments. As a result, we do not expect to incur significant expenses
in connection with these programs and have the potential for future collaborative and royalty revenues resulting from these programs.

62

Please refer to Note B, “Collaborative Arrangements,” for further information regarding our in-license agreements and out-license agreements.

Strategic Investments

In connection with our business development activities, we have periodically made equity investments in our collaborators. As of December 31, 2020, we

held strategic equity investments in several public companies and certain private companies, and we plan to make additional strategic equity investments in
the future. While we invest the majority of our cash, cash equivalents and marketable securities in instruments that meet specific credit quality standards and
limit our exposure to any one issue or type of instrument, our strategic investments are maintained and managed separately from our other cash, cash
equivalents and marketable securities. Any changes in the fair value of equity investments with readily determinable fair values (including publicly traded
securities) are recorded to other income (expense), net in our consolidated statement of operations.

In 2020, 2019 and 2018, we recorded within other income (expense), net gains of $311.9 million, $197.6 million and $2.6 million, respectively, related to

changes in the fair value of our strategic investments and from sales of certain investments. As of December 31, 2020, the fair value of our investments in
publicly traded companies was $195.8 million. To the extent that we continue to hold strategic investments, particularly strategic investments in publicly
traded companies, we will record other income (expense) related to these strategic investments on a quarterly basis. Due to the increased volatility of the
global markets, including as a result of COVID-19, and the high volatility of stocks in the biotechnology industry, we expect the value of these strategic
investments to fluctuate and that the increases or decreases in the fair value of these strategic investments will continue to have material impacts on our net
income (expense) and our profitability on a quarterly and/or annual basis.

Our net income attributable to Vertex increased to $2.71 billion in 2020 as compared to $1.18 billion in 2019 primarily due to increased revenues and
increased other income (expense) related to our strategic investments partially offset by increased operating costs and expenses and an increased provision for
income taxes. The increased revenues were primarily due to the U.S. approval of TRIKAFTA in the fourth quarter of 2019, E.U. approval of KAFTRIO in the
third quarter of 2020 and continued uptake of our medicines in ex-U.S. markets. The increased operating costs and expenses were primarily due to increased
cost of sales consistent with increased net product revenues, increased investment in research and development and increased sales, general and administrative
expenses to support our business.

Net income attributable to Vertex in 2018 included a one-time non-cash benefit from income taxes of $1.56 billion resulting from our release of our
valuation allowance. Net income attributable to Vertex decreased in 2019 as compared to 2018 as a result of this one-time tax benefit and increased operating
costs and expenses. The increases in operating costs and expenses were primarily due to increased cost of sales due to increased net product revenues and
increased research expenses associated with our business development activities. These decreases in our net income in 2019 as compared to 2018 were
partially offset by increased net product revenues and increased gains recorded to other income (expense) related to our strategic investments.

Earnings Per Share

In 2020, 2019, and 2018, net income attributable to Vertex was $10.29, $4.51 and $8.09, respectively, per diluted share. In 2018, the benefit from income

taxes as a result of the release of our valuation allowance increased net income attributable to Vertex by $6.03 per diluted share.

In 2020, our net product revenues increased by $2.04 billion as compared to 2019. In 2019, our net product revenues increased by $1.12 billion as
compared to 2018. The increase in total net product revenues in 2020 was primarily due to the launch of TRIKAFTA in the U.S in the fourth quarter of 2019
and KAFTRIO in the E.U. in the third quarter of 2020. Decreases in revenues for our other products were the result of patients in the U.S. switching from
these medicines to TRIKAFTA, partially offset by label expansions and expanded access to our medicines in ex-U.S. markets. The increase in total net
product revenues in 2019 was primarily due to the increasing number of patients being treated with SYMDEKO/SYMKEVI, the October 2019 approval of
TRIKAFTA in the U.S., label expansions for KALYDECO and ORKAMBI and expanded access to our medicines in ex-U.S. markets. In 2020, 2019 and
2018, our net product revenues included product revenues of $1.4 billion, $1.1 billion and $682.4 million, respectively, from ex-U.S. markets.

We expect that our net product revenues will increase in 2021 due to increasing numbers of people being treated with our medicines as a result of the

continued uptake of TRIKAFTA, the approval of KAFTRIO by the European Commission, label expansions for our previously approved products and
expanded access to our medicines.

Upon reaching an agreement with the French government for ORKAMBI in the fourth quarter of 2019, including the final amount for ORKAMBI
distributed through early access programs, we recognized an adjustment to increase net product revenues related to prior period shipments of ORKAMBI
distributed through early access programs of $155.8 million. Please refer to “Critical Accounting Policies - Revenue Recognition” below for a discussion of
our accounting treatment for our early access program for ORKAMBI in France.

Collaborative and Royalty Revenues

Our collaborative and royalty revenues were $2.9 million, $2.1 million and $9.3 million in 2020, 2019 and 2018, respectively. Our collaborative revenues
have historically fluctuated significantly from one period to another and may continue to fluctuate in the future. Our future royalty revenues will be dependent
on if, and when, our collaborators are able to successfully develop drug candidates that we have out-licensed to them.

Our cost of sales primarily consists of the third-party royalties payable on our net sales of our products as well as the cost of producing inventories that

corresponded to product revenues for the reporting period. Pursuant to our agreement with the Cystic Fibrosis Foundation, or CFF, our tiered third-party
royalties on sales of TRIKAFTA/KAFTRIO, SYMDEKO/SYMKEVI, KALYDECO and ORKAMBI, calculated as a percentage of net sales, range from the
single digits to the sub-teens, with royalties on sales of TRIKAFTA/KAFTRIO slightly lower than for our other products. Over the last several years, our cost
of sales has been increasing due to increased net product revenues. Our cost of sales as a percentage of our net product revenues was approximately 12%,
13%, and 13% for 2020, 2019 and 2018, respectively. In 2021, we expect our total cost of sales will increase due to expected increases in our net product
revenues and our cost of sales as a percentage of total net product revenues will be similar to our cost of sales as a percentage of total net product revenues in
2020.

Our research and development expenses include internal and external costs incurred for research and development of our drugs and drug candidates and

expenses related to certain technology that we acquire or license through business development transactions. We do not assign our internal costs, such as
salary and benefits, stock-based compensation expense, laboratory supplies and other direct expenses and infrastructure costs, to individual drugs or drug
candidates, because the employees within our research and development groups typically are deployed across multiple research and development programs.
These internal costs are significantly greater than our external costs, such as the costs of services provided to us by clinical research organizations and other
outsourced research, which we allocate by individual program. All research and development costs for our drugs and drug candidates are expensed as
incurred.

Over the past three years, we have incurred $5.0 billion in research and development expenses associated with drug discovery and development. The

successful development of our drug candidates is highly uncertain and subject to a number of risks. In addition, the duration of clinical trials may vary
substantially according to the type, complexity and novelty of the drug candidate and the disease indication being targeted. The FDA and comparable agencies
in foreign countries impose substantial requirements on the introduction of therapeutic pharmaceutical products, typically requiring lengthy and detailed
laboratory and clinical testing procedures, sampling activities and other costly and time-consuming procedures. Data obtained from nonclinical and clinical
activities at any step in the testing process may be adverse and lead to discontinuation or redirection of development activities. Data obtained from these
activities also are susceptible to varying interpretations,

66

which could delay, limit or prevent regulatory approval. The duration and cost of discovery, nonclinical studies and clinical trials may vary significantly over
the life of a project and are difficult to predict. Therefore, accurate and meaningful estimates of the ultimate costs to bring our drug candidates to market are
not available.

In 2020, 2019 and 2018, costs related to our CF programs represented the largest portion of our development costs. Any estimates regarding development
and regulatory timelines for our drug candidates are highly subjective and subject to change. Until we have data from Phase 3 clinical trials, we cannot make a
meaningful estimate regarding when, or if, a clinical development program will generate revenues and cash flows.

We expect to continue to invest in our research programs with a focus on identifying drug candidates with the goal of creating transformative medicines

for serious diseases. Our total research expenses have historically fluctuated, and are expected to continue to fluctuate, from one period to another due to
upfront and milestone payments related to our business development activities that are reflected in the preceding table as collaborative payments. Our research
expenses, excluding these collaborative payments, have been increasing over the last several years as we have invested in our pipeline and expanded our cell
and genetic therapies capabilities.

18 %

Sales, general and administrative expenses increased by 17% in 2020 as compared to 2019, and by 18% in 2019 as compared to 2018, primarily due to
increased global support for our medicines, including incremental investment to support the launch of our triple combination regimen and increased support
for our CF pipeline products and other disease areas. We expect our sales, general and administrative expenses to continue to increase in 2021.

Contingent Consideration

In 2020 and 2019, the increase in the fair value of contingent consideration potentially payable to Exonics’ former equity holders was $13.1 million and

$4.5 million, respectively, primarily due to changes in market interest rates. There were no similar amounts in 2018. In future periods, we expect the fair value
of contingent consideration to increase or decrease based on, among other things, our estimates of the probability of achieving and the timing of these
contingent development and regulatory milestone payments, as well as the time value of money changes in market interest rates.

Intangible Asset Impairment Charge

In 2018, we recorded a $29.0 million impairment charge related to VX-210 that was licensed from BioAxone Biosciences, Inc., or BioAxone, in 2014.

This charge was attributable to non-controlling interest on our consolidated statement of operations because we consolidated BioAxone as a variable interest
entity, or VIE, until December 31, 2018. There were no corresponding intangible asset impairment charges in 2020 or 2019.

Other Non-Operating Income (Expense), Net

Interest Income

Interest income increased from $38.4 million in 2018 to $63.7 million in 2019 and decreased to $22.2 million in 2020. The increase in our interest income

in 2019 as compared to 2018 was primarily due to increases in our cash equivalents and available-for-sale debt securities and prevailing market interest rates.
The decrease in our interest income in 2020 as compared to 2019 was primarily due to a decrease in prevailing market interest rates despite continued
increases in our cash equivalents and available-for-sale debt securities. Our future interest income will be dependent on the amount of, and prevailing market
interest rates on, our outstanding cash equivalents and available-for-sale debt securities.

Interest Expense

Interest expense was $58.2 million in 2020, $58.5 million in 2019 and $72.5 million in 2018. The majority of our interest expense in these periods was
related to imputed interest expense associated with our leased corporate headquarters in Boston and our research site in San Diego. On January 1, 2019, we
adopted ASC 842, Leases, which resulted in a reduction in our imputed interest expense associated with these leases in 2020 and 2019. Our future interest
expense will be dependent on whether, and to what extent, we borrow amounts under our credit facilities.

Other Income (Expense), Net

In 2020 and 2019, we recorded net other income of $296.4 million and $192.2 million, respectively, primarily related to changes in the fair value of our

strategic investments. In 2018, we recorded net other expense of $0.8 million. We expect that due to the volatility of the stock price of biotechnology
companies, our other income (expense), net will fluctuate in future periods based on increases or decreases in the fair value of our strategic investments.

68

Noncontrolling Interest (VIEs)

In 2018, our $9.8 million net loss attributable to noncontrolling interest reflects BioAxone’s net loss for the reporting period. We deconsolidated

BioAxone from our consolidated financial statements as of December 31, 2018 and did not consolidate any VIEs into our consolidated financial statements in
2020 or 2019.

Income Taxes

Our provision for income taxes was $405.2 million for 2020 and $218.1 million for 2019. Our effective tax rate of 13% for 2020 was lower than the U.S.
statutory rate primarily due to (i) discrete tax benefits associated with the $209.0 million transfer of intellectual property rights to the U.K., the write-off of a
long-term intercompany receivable, and an increase in the U.K.’s corporate tax rate; and (ii) excess tax benefits related to stock-based compensation. The
impact of these items was partially offset by a U.S. deemed dividend. Our effective tax rate of 16% for 2019 was lower than the U.S. statutory rate primarily
due to excess tax benefits related to stock-based compensation and research and development tax credits.

In 2018, we recorded a benefit from income taxes of $1.5 billion because we released our valuation allowance on the majority of our net operating losses
and other deferred tax assets in the fourth quarter of 2018, resulting in a non-cash credit to net income of $1.56 billion. Starting in 2019, we began recording a
provision for income taxes on our pre-tax income using an effective tax rate approximating statutory rates. Due to our ability to offset our pre-tax income
against previously benefited net operating losses, the majority of our tax provision in 2020 and 2019 represented a non-cash expense. We utilized substantially
all of our remaining previously benefited U.S. net operating losses in 2020. As a result, a larger portion of our tax provision will represent a cash tax payable
in future periods.

As of December 31, 2020, total working capital was $6.3 billion, which represented an increase of $2.8 billion from $3.5 billion as of December 31, 2019.

The increase in total working capital in 2020 was primarily related to $3.3 billion of cash provided by operations partially offset by $539.1 million of cash
used to repurchase our common stock pursuant our share repurchase programs and purchases of property and equipment of $259.8 million.

Sources of Liquidity

As of December 31, 2020, we had cash, cash equivalents and marketable securities of $6.7 billion, which represented an increase of $2.9 billion from $3.8

billion as of December 31, 2019. We intend to rely on our existing cash, cash equivalents and marketable securities together with cash flows from product
sales as our primary source of liquidity.

We may borrow up to a total of $2.5 billion pursuant to two revolving credit facilities. We may repay and reborrow amounts under these revolving credit

agreements without penalty. Subject to certain conditions, we may request that the borrowing capacity for each of the credit agreements be increased by an
additional $500.0 million, for a total of $3.5 billion collectively. Other possible sources of future liquidity include commercial debt, public and private
offerings of our equity and debt securities, strategic sales of assets or businesses and financial transactions. Negative covenants in our credit agreement may
prohibit or limit our ability to access these sources of liquidity. As of December 31, 2020, we were in compliance with these covenants.

69

Future Capital Requirements

We have significant future capital requirements including:

•

•

significant expected operating expenses to conduct research and development activities and to operate our organization; and

substantial facility and finance lease obligations.

In addition:

• We have entered into certain collaboration agreements with third parties that include the funding of certain research, development and

commercialization efforts. Certain of our business development transactions, including collaborations and acquisitions, include the potential for
future milestone and royalty payments by us upon the achievement of pre-established developmental and regulatory targets and/or commercial
targets. We may enter into additional business development transactions, including acquisitions, collaborations and equity investments, that require
additional capital.

•

To the extent we borrow amounts under the credit agreements we entered into in 2020 and 2019, we would be required to repay any outstanding
principal amounts in 2022 or 2024, respectively.

• As of December 31, 2020, $424.9 million remained available to fund repurchases under the 2020 Share Repurchase Program that we announced in

November 2020.

We expect that cash flows from our products together with our current cash, cash equivalents and marketable securities will be sufficient to fund our
operations for at least the next twelve months and do not expect COVID-19 to have an adverse effect on our liquidity. The adequacy of our available funds to
meet our future operating and capital requirements will depend on many factors, including the amounts of future revenues generated by our products, and the
potential introduction of one or more of our other drug candidates to the market, the level of our business development activities and the number, breadth, cost
and prospects of our research and development programs.

Financing Strategy

We may raise additional capital by borrowing under credit agreements, through public offerings or private placements of our securities or securing new

collaborative agreements or other methods of financing. We will continue to manage our capital structure and will consider all financing opportunities,
whenever they may occur, that could strengthen our long-term liquidity profile. There can be no assurance that any such financing opportunities will be
available on acceptable terms, if at all.

Leases

We lease two buildings that are located at Fan Pier in Boston, Massachusetts. We commenced lease payments on these two buildings in December 2013

and the initial lease periods end in December 2028. We also lease office and laboratory

70

space in San Diego, California. We commenced lease payments for this building in the second quarter of 2019 pursuant to an initial 16 year lease term. The
future minimum rental payments that we are obligated to pay related to the San Diego building are included in “Finance leases, excluding Fan Pier Leases,”
which also reflects leases of equipment and a land lease. The remainder of our real estate leases are reflected in “Operating leases” in the table above,
including office and laboratory space at our Cell and Genetic Therapies facility near our corporate headquarters. Base rent payments will commence for this
building in the fourth quarter of 2021 pursuant to an initial 15 year lease term.

Research and Development Costs

“Research and development costs” included in the table above primarily relate to pharmaceutical materials to be utilized in our clinical trials and research
costs related to our advancing pipeline. The amounts reflected in “Research and development costs” do not include certain payments we anticipate making to
clinical research organizations, or CROs, because these contracts are cancelable, at our option, with notice. However, we historically have not cancelled such
contracts. As of December 31, 2020, we had accrued $42.8 million related to these contracts for costs incurred for services provided through December 31,
2020, and we have approximately $237.6 million in cancelable future commitments based on existing contracts as of December 31, 2020. These amounts
reflect planned expenditures based on existing contracts and do not reflect any future modifications to, or terminations of, existing contracts or anticipated or
potential new contracts.

Collaborative Arrangements and Asset Acquisitions

We have entered into certain research and development collaboration agreements with third parties and acquired certain assets that include the funding of
certain development, manufacturing and commercialization efforts with the potential for future milestone and royalty payments by us upon the achievement of
pre-established developmental, regulatory and/or commercial targets. Our obligation to fund these efforts is contingent upon continued involvement in the
programs and/or the lack of any adverse events that could cause the discontinuance of the programs. These payments, which are not included in the
contractual obligations table above, include:

•

•

CFF: We pay royalties, which are included in cost of sales, to CFF on sales of our CF products.

Research and Development Milestones: The majority of our in-license agreements and our acquisitions have milestone and royalty payments payable
by us upon the successful achievement of pre-established developmental, regulatory and/or commercial targets or net sales. Contingent payments
under these agreements become due and payable only upon achievement of certain milestones.

Tax-related Obligations

We exclude liabilities pertaining to uncertain tax positions from our summary of contractual obligations as we cannot make a reliable estimate of the
period of cash settlement with the respective taxing authorities. As of December 31, 2020, our liabilities associated with uncertain tax positions were $86.6
million.

Other Funding Commitments

Our table detailing contractual commitments and obligations does not include severance payment obligations to certain of our executive officers in the
event of a not-for-cause employment termination under existing employment contracts. We will provide information regarding these obligations annually in
our proxy statement for our annual meeting of shareholders.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements prepared in

accordance with generally accepted accounting principles in the U.S. The preparation of these financial statements requires us to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses during the reported periods. These items are monitored and analyzed by management for
changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are reflected in reported results for
the period in which the change occurs. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under
the circumstances. Actual results may differ from our estimates if past experience or other assumptions do not turn out to be substantially accurate.

We believe that our application of the following accounting policies, each of which requires significant judgments and estimates on the part of

management, are the most critical to aid in fully understanding and evaluating our reported financial results:

•

•

•

revenue recognition;

acquisitions, including intangible assets, goodwill and contingent consideration; and

income taxes.

Our accounting policies, including the ones discussed below, are more fully described in the Notes to our consolidated financial statements, including

Note A, “Nature of Business and Accounting Policies,” included in this Annual Report on Form 10-K.

Revenue Recognition

Product Revenues, Net

We generate product revenues from sales in the U.S. and in international markets. We sell our products principally to a limited number of specialty
pharmacy and specialty distributors in the U.S., which account for the largest portion of our total revenues, and make international sales primarily to specialty
distributors and retail chains, as well as hospitals and clinics, many of which are government-owned or supported customers, collectively, our customers. Our
customers in the U.S. subsequently resell our products to patients and health care providers. We contract with government agencies so that our products will
be eligible for purchase by, or partial or full reimbursement from, such third-party payors. We recognize net product revenues from sales of our products when
our customers obtain control of our products, which typically occurs upon delivery to our customers. Revenues from our product sales are recorded at the net
sales price, or “transaction price,” which requires us to make several significant estimates regarding the net sales price.

The most significant estimate we are required to make is related to government and private payor rebates, chargebacks, discounts and fees, collectively
rebates. The value of the rebates provided to third-party payors per course of treatment vary significantly and are based on government-mandated discounts
and our arrangements with other third-party payors. In order to estimate our total rebates, we estimate the percentage of prescriptions that will be covered by
each third-party payor, which is referred to as the payor mix. We track available information regarding changes, if any, to the payor mix for our products, to
our contractual terms with third-party payors and to applicable governmental programs and regulations and levels of our products in the distribution channel.
We adjust our estimated rebates based on new information, including information regarding actual rebates for our products, as it becomes available. Claims by
third-party payors for rebates are submitted to us significantly after the related sales, potentially resulting in adjustments in the period in which the new
information becomes known. Our credits to revenue related to prior period sales, excluding the adjustment to the transaction price for ORKAMBI distributed
through early access programs in France in 2019, have not been significant (typically less than 1% of gross product revenues) and primarily related to U.S.
rebates.

72

The following table summarizes activity related to our accruals for rebates (including our refund liability to the French government related to ORKAMBI

distributed through early access programs in France as described below) for the three years ended December 31, 2020:

We have also entered into annual contracts with government-owned and supported customers in international markets that limit the amount of annual
reimbursement we can receive. Upon exceeding the annual reimbursement amount, products are provided free of charge, which is a material right. We defer a
portion of the consideration received, which includes upfront payments and fees, for shipments made up to the annual reimbursement limit as “Other current
liabilities.” The deferred amount is recognized as revenue when the free products are shipped. In order to estimate the portion of the consideration received to
recognize as revenue and the portion of the amount to defer, we rely on our forecast of the number of units we will distribute during the applicable annual
period in each international market in which our contracts with government-owned and supported customers limit the amount of annual reimbursement we can
receive. Our forecasts are based on, among other things, our historical experience.

The preceding estimates and judgments materially affect our recognition of net product revenues. Changes in our estimates of net product revenues could

have a material effect on net product revenues recorded in the period in which we determine that change occurs.

French Early Access Programs

In 2015, we began distributing ORKAMBI through early access programs in France and remained engaged in reimbursement discussions with the French
government for ORKAMBI, including ORKAMBI distributed through early access programs, until November 2019, when we reached an agreement with the
French government. From the time we began distributing ORKAMBI through early access programs in France, we expected that the difference between the
amounts collected based on the invoiced amount and the final amount for ORKAMBI distributed through these programs would be returned to the French
government. Our refund liability related to the early access programs in France was classified in “Accrued expenses” on our consolidated balance sheets.

From the first quarter of 2018 through the third quarter of 2019, we recognized net product revenues for ORKAMBI sales in France under the early access

programs based on a transaction price that reflected our estimate of consideration we expected to retain that would not be subject to a significant reversal in
amounts recognized, which resulted in revenue representing a portion of the invoiced amount.

Upon reaching an agreement with the French government for ORKAMBI, including the final amount for ORKAMBI distributed through early access

programs in France in the fourth quarter of 2019, we updated the transaction price related to ORKAMBI distributed through early access programs and
recognized net product revenues of $155.8 million related to these shipments, which occurred from 2015 through the date of our agreement with the French
government, because the final amount for these shipments exceeded our previous estimate.

73

Acquisitions

We are required to make several significant judgments and estimates in order to calculate the purchase price for our business combinations and then
allocate it to the assets that we have acquired and the liabilities that we have assumed on our consolidated balance sheet. The most significant judgments and
estimates relate to the fair value of the in-process research and development assets and contingent consideration liabilities related to these business
combinations. Based on these judgments and estimates, the fair value of the goodwill that we record as a result of these business combinations may be
material. Once recorded, these assets are subject to quarterly impairment analysis and our contingent consideration liability is adjusted quarterly, which
requires similar judgments and estimates.

Intangible Assets

In 2019, we recorded in-process research and development assets related to our acquisitions of Exonics and Semma totaling $400.0 million on our

consolidated balance sheet, which remained on our consolidated balance sheet as of December 31, 2020. Each of these assets is accounted for as an indefinite-
lived intangible asset and is maintained on our consolidated balance sheet until either the project underlying it is completed or the asset becomes impaired.
When we determine that an asset has become impaired or we abandon a project, we write down the carrying value of the related intangible asset to its fair
value and record an impairment charge in the period in which the impairment occurs. In 2018, we recorded a full impairment charge of $29.0 million for the
in-process research and development asset that had previously been recorded on our consolidated balance sheets related to our collaboration with BioAxone.

To determine the fair value of our in-process research and development assets, we utilize the multi-period excess earnings method of the income

approach, which requires us to make estimates of the probability of technical and regulatory success, development cost assumptions, revenue projections and
growth rates, commercial cost estimates and appropriate discount rates. These assumptions require significant management judgment and reasonable changes
in the assumptions can cause material changes to the fair value of the intangible assets. Due to the early stage of Exonics and Semma’s programs, these
significant assumptions could be affected by future economic and market conditions.

Contingent Consideration

As of December 31, 2020 and 2019, we had $189.6 million and $176.5 million, respectively, of liabilities on our consolidated balance sheet attributable to

the fair value of the contingent development and regulatory payments that we may owe to Exonics’ former equity holders upon the achievement of certain
events. Our acquisition of Semma in 2019 did not include similar contingent payments; therefore, we are not required to record contingent consideration
liabilities related to our acquisition of Semma.

We record an increase or a decrease in the fair value of the contingent consideration liability on our consolidated balance sheet and in our consolidated
statement of operations on a quarterly basis. We determine the fair value of our contingent consideration liability using a probability weighted discounted cash
flow method of the income approach, which requires us to make estimates of the timing of regulatory and commercial milestone achievement and the
corresponding estimated probability of technical and regulatory success rates. Significant judgment is used in determining the appropriateness of these
assumptions during each reporting period. Reasonable changes in these assumptions can cause material changes to the fair value of our contingent
consideration liability. Due to the early stage of Exonics’ DMD and DM1 programs, these significant assumptions could be affected by future economic and
market conditions.

Goodwill

In 2020, we did not have any business combinations; therefore, we did not record any additional goodwill on our consolidated balance sheet. In 2019, we

recorded goodwill of $554.6 million and $397.1 million related to our acquisitions of Semma and Exonics, respectively. Goodwill reflects the difference
between the fair value of the consideration transferred and the fair value of the net assets acquired. Thus, the goodwill that we record is dependent on the
significant judgments and estimates inherent in the fair value of our in-process research and development assets and contingent consideration liabilities.

Income Taxes

We utilize the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the

difference between the financial statement carrying amounts and tax basis of assets and liabilities using enacted tax rates in effect for years in which the
temporary differences are expected to reverse. If our estimate

74

of the tax effect of reversing temporary differences is (i) not reflective of actual outcomes, (ii) modified to reflect new developments or interpretations of the
tax law, or (iii) revised to incorporate new accounting principles, or changes in the expected timing or manner of the reversal, our results of operations could
be materially impacted.

We are engaged in research and development activities and incurred significant net operating losses for a number of years before recently becoming
profitable. Accordingly, we did not report any tax benefits relating to our net operating loss carryforwards and income tax credit carryforwards that were
available for utilization in future periods because we maintained a valuation allowance on the majority of our net operating losses and other deferred tax assets
until December 31, 2018. We released the valuation allowance on the majority of our net operating losses and other deferred tax assets resulting in a non-cash
benefit from income taxes of $1.56 billion in the fourth quarter of 2018.

We provide a valuation allowance when it is more likely than not that deferred tax assets will not be realized. On a periodic basis, we reassess our
valuation allowances on our deferred tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. In the fourth
quarter of 2018, we reassessed our valuation allowances and considered positive evidence including significant cumulative consolidated and U.S. income over
the three years ended December 31, 2018, revenue growth, clinical program progression, including the advancement and clinical trial data from our triple
combination regimens, and expectations regarding future profitability, and negative evidence, including potential impact of competition on our projections and
cumulative losses in the jurisdictions. After assessing both the positive evidence and the negative evidence, we released the valuation allowance on the
majority of our net operating losses and other deferred tax assets as of December 31, 2018.

Significant judgment is required in making these assessments to maintain or reverse our valuation allowances and, to the extent our future expectations

change we would have to assess the recoverability of these deferred tax assets at that time. The determination to release the majority of our valuation
allowances increased our net income by $1.56 billion, or $6.03 per share in 2018.

RECENT ACCOUNTING PRONOUNCEMENTS

Refer to Note A, “Nature of Business and Accounting Policies,” in the accompanying notes to the consolidated financial statements for a discussion of

recent accounting pronouncements and new accounting pronouncements adopted during 2020.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As part of our investment portfolio, we own financial instruments that are sensitive to market risks. The investment portfolio is used to preserve our
capital. None of these market risk-sensitive instruments are held for trading purposes. We do not have derivative financial instruments in our investment
portfolio.

Interest Rate Risk

We invest our cash in a variety of financial instruments, principally securities issued by the U.S. government and its agencies, investment-grade corporate
bonds and commercial paper, and money market funds. These investments are denominated in U.S. Dollars. All of our interest-bearing securities are subject to
interest rate risk and could decline in value if interest rates fluctuate, including potential fluctuations as a result of COVID-19. Substantially all of our
investment portfolio consists of marketable securities with active secondary or resale markets to help ensure portfolio liquidity, and we have implemented
guidelines limiting the term-to-maturity of our investment instruments. Due to the conservative nature of these instruments, we do not believe that we have a
material exposure to interest rate risk. If interest rates were to increase or decrease by 1%, the fair value of our investment portfolio would increase or decrease
by an immaterial amount.

We entered into a credit agreement in each of 2020 and 2019. Loans under these credit agreements bear interest, at our option, at either a base rate or a

Eurocurrency rate, in each case plus an applicable margin based on our consolidated leverage ratio (the ratio of our total consolidated funded indebtedness to
our consolidated EBITDA for the most recently completed four fiscal quarter period). Pursuant to the credit agreement that we entered into in 2019, the
applicable margin on base rate loans ranges from 0.125% to 0.500% and the applicable margin on Eurocurrency loans ranges from 1.125% to 1.500%.
Pursuant to the credit agreement that we entered into in 2020, the applicable margin on base rate loans ranges from 0.500% to 0.875% and the applicable
margin on Eurocurrency loans ranges from 1.500% to 1.875%. We do not believe that changes in interest rates related to either credit agreement would have a
material effect on our consolidated financial statements. As

75

of December 31, 2020, we had no principal or interest outstanding under either of our existing credit facilities. A portion of our “Interest expense” in 2021 will
be dependent on whether, and to what extent, we borrow amounts under these existing facilities.

Foreign Exchange Market Risk

As a result of our foreign operations, we face exposure to movements in foreign currency exchange rates, primarily the Euro and British Pound against the

U.S. Dollar. Fluctuations in the global markets, including as a result of COVID-19, may have a positive or negative effect on our foreign exchange rate
exposure. The current exposures arise primarily from cash, accounts receivable, intercompany receivables and payables, payables and accruals and
inventories. Both positive and negative effects to our net revenues from international product sales from movements in exchange rates are partially mitigated
by the natural, opposite effect that exchange rates have on our international operating costs and expenses.

We have a foreign currency management program with the objective of reducing the effect of exchange rate fluctuations on our operating results and
forecasted revenues and expenses denominated in foreign currencies. We currently have cash flow hedges for the Euro, British Pound, Canadian Dollar and
Australian Dollar related to a portion of our forecasted product revenues that qualify for hedge accounting treatment under U.S. GAAP. We do not seek hedge
accounting treatment for our foreign currency forward contracts related to monetary assets and liabilities that impact our operating results. As of December 31,
2020, we held foreign exchange forward contracts that were designated as cash flow hedges with notional amounts totaling $1.1 billion representing a net
liability of $63.5 million recorded on our consolidated balance sheet.

Although not predictive in nature, we believe a hypothetical 10% threshold reflects a reasonably possible near-term change in exchange rates. Assuming

that the December 31, 2020 exchange rates were to change by a hypothetical 10%, the fair value recorded on our consolidated balance sheet related to our
foreign exchange forward contracts that were designated as cash flow hedges as of December 31, 2020 would change by approximately $109.2 million.
However, since these contracts hedge a specific portion of our forecasted product revenues denominated in certain foreign currencies, any change in the fair
value of these contracts is recorded in “Accumulated other comprehensive loss” on our consolidated balance sheet and is reclassified to earnings in the same
periods during which the underlying product revenues affect earnings. Therefore, any change in the fair value of these contracts that would result from a
hypothetical 10% change in exchange rates would be entirely offset by the change in value associated with the underlying hedged product revenues resulting
in no impact on our future anticipated earnings and cash flows with respect to the hedged portion of our forecasted product revenues.

ITEM 9A.CONTROLS AND PROCEDURES

(1) Evaluation of Disclosure Controls and Procedures. The Company’s chief executive officer and chief financial officer, after evaluating the
effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Securities
Exchange Act of 1934, as amended) as of the end of the period covered by this Annual Report on Form 10-K, have concluded that, based on such evaluation,
the Company’s disclosure controls and procedures were effective. In designing and evaluating the disclosure controls and procedures, the Company’s
management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the
desired control objectives, and the Company’s management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of
possible controls and procedures.

(2) Management’s Annual Report on Internal Control Over Financial Reporting. The management of the Company is responsible for establishing
and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f)
promulgated under the Securities Exchange Act of 1934, as amended, as a process designed by, or under the supervision of, the Company’s principal executive
and principal financial officers and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting
principles. The Company’s internal control over financial reporting includes those policies and procedures that:

•    pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the

Company;

•    provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of
management and directors of the Company; and

•    provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that

could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation

of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2020. In making
this assessment, it used the criteria set forth in the Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO). Based on its assessment, the Company’s management has concluded that, as of December 31, 2020, the Company’s
internal control over financial reporting is effective based on those criteria.

The Company’s independent registered public accounting firm, Ernst & Young LLP, issued an attestation report on the Company’s internal control over

financial reporting. See Section 4 below.

(3) Changes in Internal Controls. During the quarter ended December 31, 2020, there were no changes in the Company’s internal control over financial

reporting that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

(4) Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Vertex Pharmaceuticals Incorporated

Opinion on Internal Control over Financial Reporting

We  have  audited  Vertex  Pharmaceuticals  Incorporated’s  internal  control  over  financial  reporting  as  of  December  31,  2020,  based  on  criteria  established  in
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO
criteria).  In  our  opinion,  Vertex  Pharmaceuticals  Incorporated  (the  Company)  maintained,  in  all  material  respects,  effective  internal  control  over  financial
reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2020 consolidated
financial statements of the Company and our report dated February 11, 2021, expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of
internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility
is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the
PCAOB  and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  testing  and
evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk,  and  performing  such  other  procedures  as  we  considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the  transactions  and  dispositions  of  the  assets  of  the  company;  (2)  provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being
made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or
timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

To the Shareholders and the Board of Vertex Pharmaceuticals Incorporated

Opinion on the Financial Statements

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheets of Vertex Pharmaceuticals Incorporated (the Company) as of December 31, 2020 and 2019,
the related consolidated statements of operations, comprehensive income, shareholders’ equity and noncontrolling interest, and cash flows for each of the three
years in the period ended December 31, 2020, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the
consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results
of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting
principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s
internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 11, 2021, expressed an unqualified
opinion thereon.

Adoption of New Accounting Standard

ASU No. 2016-02

As discussed in Note A to the consolidated financial statements, the Company changed its method for lease accounting as a result of the adoption of ASU No.
2016-02, Leases (Topic 842), and the related amendments effective January 1, 2019.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company
in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures
to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks.
Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial
statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required
to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our
especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the
consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the
critical audit matter or on the accounts or disclosures to which it relates.

Description of the
Matter

Revenue recognition - Payor Mix Impact on Measuring Variable Consideration
As discussed in Note A to the Company’s consolidated financial statements, the Company records product sales at the net sales price,
or  “transaction  price,”  which  requires  the  Company  to  make  several  significant  estimates  regarding  the  net  sales  price.  The  most
significant estimates relate to government rebates, chargebacks, discounts and fees, collectively rebates. Due to the delay in receipt of
claims by third-party payors, the Company estimates the percentage of prescriptions that will be covered by each third-party payor,
which is referred to as the payor mix. Rebate accruals inclusive of estimated amounts due for claims not yet received or processed are
recorded within accrued expenses on the Company’s consolidated balance sheet.

Auditing  the  measurement  of  the  Company’s  net  product  revenues  was  especially  complex  and  judgmental  due  to  the  significant
estimation required in determining the amount of consideration that will be collected net of estimates for payor rebates. In particular,
the net sales price is affected by assumptions in payor behavior such as changes in payor mix, payor collections, current customer
contractual requirements, and experience with ultimate collection from third-party payors.

How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s revenue
recognition process, including controls over the underlying assumptions and inputs used by management to estimate amounts due to
third-party  payors  and  the  completeness  and  accuracy  of  the  data  used  in  the  estimates.  We  also  tested  the  Company’s  controls  to
assess the completeness and accuracy of the current and historical data that supports the estimate.

Our audit procedures to test the Company’s recognition of net product revenues included, among others, assessing the methodology
used to determine the estimate and testing the significant assumptions and the underlying data used by the Company in its analysis,
which included historical claims data. To assess the payor mix assumptions we tested contracted rates, historical claims and payment
data and related trends, and other relevant factors. We also assessed the historical accuracy of the Company’s estimates of third-party
payor rebates.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2005.

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements

A. Nature of Business and Accounting Policies

Business

Vertex Pharmaceuticals Incorporated (“Vertex” or the “Company”) invests in scientific innovation to create transformative medicines for serious diseases.

The Company’s business is focused on developing and commercializing therapies for the treatment of cystic fibrosis (“CF”) and advancing research and
development programs in other indications. The Company’s marketed products are TRIKAFTA/KAFTRIO (elexacaftor/tezacaftor/ivacaftor and ivacaftor),
SYMDEKO/SYMKEVI (tezacaftor in combination with ivacaftor), ORKAMBI (lumacaftor in combination with ivacaftor) and KALYDECO (ivacaftor),
which are approved to treat people with CF who have specific mutations in their cystic fibrosis transmembrane conductance regulator (“CFTR”) gene.

As of December 31, 2020, the Company had cash, cash equivalents and marketable securities of $6.7 billion. The Company expects that cash flows from
the sales of its products, together with its cash, cash equivalents and marketable securities, will be sufficient to fund its operations for at least the next twelve
months.

The Company is subject to risks common to companies in its industry including, but not limited to, the dependence on revenues from its CF products,

competition, uncertainty about clinical trial outcomes and regulatory approvals, uncertainties relating to pharmaceutical pricing and reimbursement,
uncertainty related to international expansion, uncertain protection of proprietary technology, the need to comply with government regulations, share price
volatility, dependence on collaborative relationships and potential product liability.

Basis of Presentation

The accompanying consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the
United States of America (“U.S. GAAP”), reflect the operations of (i) the Company, (ii) its wholly-owned subsidiaries and (iii) a consolidated variable interest
entity (“VIE”). In 2018, the Company deconsolidated BioAxone Biosciences, Inc. (“BioAxone”), a VIE the Company had consolidated since 2014. As of
December 31, 2020 and 2019, the Company did not have any consolidated VIEs. All material intercompany balances and transactions have been eliminated.
The Company operates in one segment, pharmaceuticals. Please refer to Note Q, “Segment Information,” for enterprise-wide disclosures regarding the
Company’s revenues, major customers and long-lived assets by geographic area. The Company has reclassified certain items from the prior year’s
consolidated financial statements to conform to the current year’s presentation.

Use of Estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that

affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and
the amounts of revenues and expenses during the reported periods. Significant estimates in these consolidated financial statements have been made in
connection with (i) determining the transaction price of revenues, (ii) accounting for acquisitions, including intangible assets, goodwill and contingent
consideration and (iii) evaluating deferred tax asset valuation allowances and the provision for income taxes. The Company bases its estimates on historical
experience and various other assumptions, including in certain circumstances future projections that management believes to be reasonable under the
circumstances. Actual results could differ from those estimates. Changes in estimates are reflected in reported results in the period in which they become
known.

Notes to Consolidated Financial Statements (Continued)

Revenue Recognition

The Company recognizes revenue when a customer obtains control of promised goods or services. The Company records the amount of revenue that

reflects the consideration that it expects to receive in exchange for those goods or services. The Company applies the following five-step model in order to
determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are
performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint
on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company
satisfies each performance obligation. 

The Company only applies the five-step model to contracts when it is probable that it will collect the consideration to which it is entitled in exchange for

the goods or services that it transfers to the customer. Once a contract is determined to be within the scope of Accounting Standards Codification (“ASC”)
606, Revenue from Contracts with Customers (“ASC 606”) at contract inception, the Company reviews the contract to determine which performance
obligations it must deliver and which of these performance obligations are distinct. The Company recognizes as revenue the amount of the transaction price
that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied. Generally, the Company’s performance
obligations are transferred to customers at a point in time, typically upon delivery.

Product Revenues, Net

The Company sells its products principally to a limited number of specialty pharmacy and specialty distributors in the United States (“U.S.”), which
account for the largest portion of its total revenues, and makes international sales primarily to specialty distributors and retail chains, as well as hospitals and
clinics, many of which are government-owned or supported (collectively, its “Customers”). The Company’s Customers in the U.S. subsequently resell the
products to patients and health care providers. The Company recognizes net product revenues from sales when the Customers obtain control of the Company’s
products, which typically occurs upon delivery to the Customer. The Company’s payment terms are approximately 30 days in the U.S. and consistent with
prevailing practice in international markets.

Revenues from product sales are recorded at the net sales price, or “transaction price,” which includes estimates of variable consideration that result from
(a) invoice discounts for prompt payment and distribution fees, (b) government and private payor rebates, chargebacks, discounts and fees and (c) costs of co-
pay assistance programs for patients, as well as other incentives for certain indirect customers. Reserves are established for the estimates of variable
consideration based on the amounts earned or to be claimed on the related sales. The reserves are classified as reductions to “Accounts receivable, net” if
payable to a Customer or “Accrued expenses” if payable to a third-party. Where appropriate, the Company utilizes the expected value method to determine the
appropriate amount for estimates of variable consideration based on factors such as the Company’s historical experience, current contractual and statutory
requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. The amount of variable
consideration that is included in the transaction price may be constrained and is included in net product revenues only to the extent that it is probable that a
significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received
may differ from the Company’s estimates. If actual results vary from the Company’s estimates, the Company adjusts these estimates, which would affect net
product revenue and earnings in the period such variances become known.

Invoice Discounts and Distribution Fees: The Company generally provides invoice discounts on product sales to its Customers for prompt payment

and pays fees for distribution services, such as fees for certain data that Customers provide to the Company. The Company estimates that, based on its
experience, its Customers will earn these discounts and fees, and deducts the full amount of these discounts and fees from its gross product revenues and
accounts receivable at the time such revenues are recognized.

Rebates, Chargebacks, Discounts and Fees: The Company contracts with government agencies (its “Third-party Payors”) so that products will be
eligible for purchase by, or partial or full reimbursement from, such Third-party Payors. The Company estimates the rebates, chargebacks, discounts and
fees it will provide to Third-party Payors and deducts these estimated amounts from its gross product revenues at the time the revenues are recognized.
For each product, the Company estimates the aggregate rebates, chargebacks and discounts that it will provide to Third-party Payors based upon (i) the
Company’s contracts with these Third-party Payors, (ii) the government-mandated discounts and fees

F-9

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

applicable to government-funded programs, (iii) information obtained from the Company’s Customers and other third-party data regarding the payor mix
for such product and (iv) historical experience.

Other Incentives: Other incentives that the Company offers include co-pay mitigation rebates provided by the Company to commercially insured
patients who have coverage and who reside in states that permit co-pay mitigation programs. Based upon the terms of the Company’s co-pay mitigation
programs, the Company estimates average co-pay mitigation amounts for each of its products in order to establish appropriate accruals.

The Company makes significant estimates and judgments that materially affect its recognition of net product revenues. The Company adjusts its estimated
rebates, chargebacks and discounts based on new information, including information regarding actual rebates, chargebacks and discounts for its products, as it
becomes available. Claims by third-party payors for rebates, chargebacks and discounts frequently are submitted to the Company significantly after the related
sales, potentially resulting in adjustments in the period in which the new information becomes known. The Company’s credits to product revenue related to
prior period sales have not been significant and primarily related to rebates and discounts.

The Company excludes taxes collected from Customers relating to product sales and remitted to governmental authorities from revenues.

Contract Liabilities

The Company recorded contract liabilities of $191.5 million and $62.3 million as of December 31, 2020 and 2019, respectively, related to annual

contracts with government-owned and supported customers in international markets that limit the amount of annual reimbursement the Company can receive.
Upon exceeding the annual reimbursement amount, products are provided free of charge, which is a material right. These contracts include upfront payments
and fees. The Company defers a portion of the consideration received for shipments made up to the annual reimbursement limit as a portion of “Other current
liabilities.” The deferred amount is recognized as revenue when the free products are shipped. The Company’s product revenue contracts include performance
obligations that are one year or less.

The Company’s contract liabilities at the end of each fiscal year relate to contracts with annual reimbursement limits in international markets in which the

annual period associated with the contract is not the same as the Company’s fiscal year. In these markets the Company recognizes revenues related to
performance obligations satisfied in previous years; however, these revenues do not relate to any performance obligations that were satisfied more than 12
months prior to the beginning of the current year. During the years ended December 31, 2020, 2019 and 2018, the Company recorded $62.3 million, $24.9
million and $1.7 million, respectively, of revenues that were recorded as contract liabilities at the beginning of the year.

French Early Access Programs

In 2015, the Company began distributing ORKAMBI through early access programs in France and remained engaged in reimbursement discussions with
the French government until November 2019, when the Company reached an agreement with the French government for ORKAMBI, including ORKAMBI
distributed through early access programs. From the time the Company began distributing ORKAMBI through early access programs in France, it expected
the difference between the amounts collected based on the invoiced amount and the final amount for ORKAMBI distributed through early access programs
would be returned to the French government. As a result, the Company had classified a refund liability related to the early access programs in France within
“Accrued expenses” on its consolidated balance sheets.

From the first quarter of 2018 through the third quarter of 2019, the Company recognized net product revenues for ORKAMBI sales in France under the
early access programs based on a transaction price that reflected the Company’s estimate of consideration it expected to retain that would not be subject to a
significant reversal in amounts recognized. When determining if variable consideration should be constrained, the Company considers whether there are
factors outside its control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and
magnitude of a potential reversal of revenue.

Upon reaching an agreement with the French government for ORKAMBI, including ORKAMBI distributed through early access programs in November

2019, the Company updated the transaction price to reflect the final amount for ORKAMBI distributed through early access programs. As a result, the
Company recognized net product revenues of

F-10

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

$155.8 million related to prior period ORKAMBI early access program sales in the fourth quarter of 2019 because the updated transaction price for
ORKAMBI distributed through these programs exceeded the Company’s previous estimate of the consideration it expected to retain that would not be subject
to a significant reversal in amounts recognized. The Company paid the final amount due to the French government in 2020.

Collaborative and Royalty Revenues

The Company has not recorded significant collaborative and royalty revenues during the three years ended December 31, 2020; however, in future
periods, it may recognize collaborative revenues generated through collaborative research, development and/or commercialization agreements. The terms of
these agreements typically include payment to the Company related to one or more of the following: nonrefundable, upfront license fees; development and
commercial milestones; funding of research and/or development activities; and royalties on net sales of licensed products. Revenue is recognized upon
satisfaction of a performance obligation by transferring control of a good or service to the collaborator.

For each collaborative research, development and/or commercialization agreement that results in revenue, the Company identifies all material

performance obligations, which may include a license to intellectual property and know-how, research and development activities and/or transition activities.
In order to determine the transaction price, in addition to any upfront payment, the Company estimates the amount of variable consideration at the outset of the
contract either utilizing the expected value or most likely amount method, depending on the facts and circumstances relative to the contract. The Company
constrains (reduces) the estimate of variable consideration such that it is probable that a significant reversal of previously recognized revenue will not occur
throughout the life of the contract. When determining if variable consideration should be constrained, management considers whether there are factors outside
the Company’s control that could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and
magnitude of a potential reversal of revenue. These estimates are re-assessed each reporting period as required.

Once the estimated transaction price is established, amounts are allocated to the performance obligations that have been identified. The transaction price

is generally allocated to each separate performance obligation on a relative standalone selling price basis. In order to account for these agreements, the
Company must develop assumptions that require judgment to determine the standalone selling price, which may include (i) the probability of obtaining
marketing approval for the drug candidate, (ii) estimates regarding the timing of and the expected costs to develop and commercialize the drug candidate,
(iii) estimates of future cash flows from potential product sales with respect to the drug candidate and (iv) appropriate discount and tax rates. Standalone
selling prices used to perform the initial allocation are not updated after contract inception. The Company does not include a financing component to its
estimated transaction price at contract inception unless it estimates that certain performance obligations will not be satisfied within one year.

Upfront License Fees: If a license to the Company’s intellectual property is determined to be distinct from the other performance obligations
identified in an arrangement, the Company recognizes revenue from the related nonrefundable, upfront license fees based on the relative standalone
selling price prescribed to the license compared to the total selling price of the arrangement. The revenue is recognized when the license is transferred to
the collaborator and the collaborator is able to use and benefit from the license. For licenses that are not distinct from other obligations identified in the
arrangement, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined
performance obligation is satisfied over time or at a point in time. If the combined performance obligation is satisfied over time, the Company applies an
appropriate method of measuring progress for purposes of recognizing revenue from nonrefundable, upfront license fees. The Company evaluates the
measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

F-11

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

Development and Regulatory Milestone Payments: Depending on facts and circumstances, the Company may conclude that it is appropriate to
include certain milestones in the estimated transaction price or that it is appropriate to fully constrain the milestones. A milestone payment is included in
the transaction price in the reporting period that the Company concludes that it is probable that recording revenue in the period will not result in a
significant reversal in amounts recognized in future periods. This may result in revenues from certain milestones and a corresponding contract asset being
recorded in a reporting period before the milestone is achieved. Milestone payments that have not been included in the transaction price to date are fully
constrained until the Company concludes that their achievement is probable and that recognition of the related revenue will not result in a significant
reversal in amounts recognized in future periods. The Company re-evaluates the probability of achievement of such development milestones and any
related constraint each reporting period and adjusts its estimate of the overall transaction price, including the amount of collaborative revenue that it has
recorded, if necessary.

Research and Development Activities/Transition Services: If the Company is entitled to reimbursement from its collaborators for specified research

and development expenses, it accounts for the related services that it provides as separate performance obligations if it determines that these services
represent a material right. The Company also determines whether the reimbursement of research and development expenses should be accounted for as
collaborative revenues or an offset to research and development expenses in accordance with the provisions of gross or net revenue presentation. The
Company recognizes the corresponding revenues or records the corresponding offset to research and development expenses as it satisfies the related
performance obligations.

Sales-based Milestone and Royalty Payments: The Company’s collaborators may be required to pay the Company sales-based milestones or royalties

on future sales of commercial products. The Company recognizes revenues related to sales-based milestone and royalties upon the later to occur of (i)
achievement of the collaborator’s underlying sales or (ii) satisfaction of any performance obligation(s) related to these sales, in each case assuming the
license to the Company’s intellectual property is deemed to be the predominant item to which the sales-based milestones and/or royalties relate.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of money market funds and marketable
securities. The Company places these investments with highly rated financial institutions, and, by policy, limits the amounts of credit exposure to any one
financial institution. These amounts at times may exceed federally insured limits. The Company also maintains a foreign currency hedging program that
includes foreign currency forward contracts with several counterparties. The Company has not experienced any credit losses related to these financial
instruments and does not believe it is exposed to any significant credit risk related to these instruments.

The Company also is subject to credit risk from its accounts receivable related to its product sales and collaborators. The Company evaluates the
creditworthiness of each of its customers and has determined that all of its material customers are creditworthy. To date, the Company has not experienced
significant losses with respect to the collection of its accounts receivable. The Company believes that its allowances, which are not significant to its
consolidated financial statements, are adequate at December 31, 2020. Please refer to Note Q, “Segment Information,” for further information.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.

Marketable Securities

As of December 31, 2020, the Company’s marketable securities consisted of investments in available-for-sale debt securities and corporate equity
securities with readily determinable fair values. The Company classifies marketable securities available to fund current operations as current assets on its
consolidated balance sheets. Marketable securities are classified as long-term assets on the consolidated balance sheets if (i) they have been in an unrealized
loss position for longer than one year and (ii) the Company has the ability and intent to hold them (a) until the carrying value is recovered and (b) such holding

F-12

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

period may be longer than one year. The Company’s marketable securities are stated at fair value. The fair value of these securities is based on quoted prices
for identical or similar assets.

The Company records unrealized gains (losses) on available-for-sale debt securities as a component of “Accumulated other comprehensive loss,” which is

a separate component of shareholders’ equity on its consolidated balance sheet, until such gains and losses are realized. Realized gains and losses, if any, are
determined using the specific identification method.

The Company records changes in the fair value of its investments in corporate equity securities to “Other income (expense), net” in its consolidated
statements of operations. Realized gains and losses, which are also included in “Other income (expense), net,” are determined on an original weighted-average
cost basis.

The Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit
Losses on Financial Instruments (“ASU 2016-13”) as of January 1, 2020, which did not have a significant impact on its consolidated financial statements. For
available-for-sale debt securities in unrealized loss positions, ASU 2016-13 requires the Company to record an allowance for credit losses using an expected
loss model, which replaces the incurred loss model required under the previous guidance. A credit loss is limited to the amount by which the amortized cost of
an investment exceeds its fair value. A previously recognized credit loss may be decreased in subsequent periods if the Company’s estimate of fair value for
the investment increases. To determine whether to record a credit loss, the Company considers issuer specific credit ratings and historical losses as well as
current economic conditions and its expectations for future economic conditions.

Accounts Receivable

The Company deducts invoice discounts for prompt payment and fees for distribution services from its accounts receivable based on its experience that
the Company’s Customers will earn these discounts and fees. The Company’s estimates for its allowance for credit losses, which has not been significant to
date, is determined based on existing contractual payment terms, historical payment patterns, current economic conditions and the Company’s expectation for
future economic conditions.

Stock-based Compensation Expense

The Company expenses the fair value of employee restricted stock units and other forms of stock-based employee compensation over the associated
employee service period on a straight-line basis. Stock-based compensation expense is determined based on the fair value of the award at the grant date and is
adjusted each period to reflect actual forfeitures and the outcomes of certain performance conditions.

For awards with performance conditions in which the award does not vest unless the performance condition is met, the Company recognizes expense if,
and to the extent that, the Company estimates that achievement of the performance condition is probable. If the Company concludes that vesting is probable, it
recognizes expense from the date it reaches this conclusion through the estimated vesting date.

The Company provides to employees who have rendered a certain number of years of service to the Company and meet certain age requirements, partial

or full acceleration of vesting of these equity awards, subject to certain conditions including a notification period, upon a termination of employment other
than for cause. Approximately 5% of the Company’s employees were eligible for partial or full acceleration of any of their equity awards as of December 31,
2020. The Company recognizes stock-based compensation expense related to these awards over a service period reflecting qualified employees’ eligibility for
partial or full acceleration of vesting.

Research and Development Expenses

The Company expenses as incurred all research and development expenses, including amounts funded by research and development collaborations. The

Company capitalizes nonrefundable advance payments made by the Company for research and development activities and expenses the payments as the
related goods are delivered or the related services are performed.

F-13

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

Research and development expenses are comprised of costs incurred by the Company in performing research and development activities, including salary
and benefits; stock-based compensation expense; outsourced services and other direct expenses, including clinical trial and pharmaceutical development costs;
collaborative payments; and infrastructure costs, including facilities costs and depreciation expense.

Inventories

The Company values its inventories at the lower-of-cost or net realizable value. The Company determines the cost of its inventories, which includes

amounts related to materials and manufacturing overhead, on a first-in, first-out basis. The Company performs an assessment of the recoverability of
capitalized inventory during each reporting period, and writes down any excess and obsolete inventories to their net realizable value in the period in which the
impairment is first identified. Shipping and handling costs incurred for inventory purchases are capitalized and recorded upon sale in “Cost of sales” in the
consolidated statements of operations. Shipping and handling costs incurred for product shipments are recorded as incurred in “Cost of sales” in the
consolidated statements of operations.

The Company capitalizes inventories produced in preparation for initiating sales of a drug candidate when the related drug candidate is considered to have
a high likelihood of regulatory approval and the related costs are expected to be recoverable through sales of the inventories. In determining whether or not to
capitalize such inventories, the Company evaluates, among other factors, information regarding the drug candidate’s safety and efficacy, the status of
regulatory submissions and communications with regulatory authorities and the outlook for commercial sales, including the existence of current or anticipated
competitive drugs and the availability of reimbursement. In addition, the Company evaluates risks associated with manufacturing the drug candidate and the
remaining shelf-life of the inventories.

Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation. Depreciation expense is recorded using the straight-line method over the

estimated useful life of the related asset generally as follows:

Description

Buildings and improvements

Furniture and equipment

Estimated Useful Life
15 to 40 years

7 to 10 years

Leasehold improvements; assets under finance leases

Computers and software

The shorter of the useful life of the assets or the estimated remaining term of the
associated lease
3 to 5 years

Maintenance and repairs to an asset that do not improve or extend its life are charged to operations. When assets are retired or otherwise disposed of, the

assets and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the Company’s consolidated
statements of operations. The Company performs an assessment of the fair value of the assets if indicators of impairment are identified during a reporting
period and records the assets at the lower of the net book value or the fair value of the assets.

The Company capitalizes internal costs incurred to develop software for internal use during the application development stage. Amortization of

capitalized internally developed software costs is recorded in depreciation expense over the useful life of the related asset.

Leases

The Company adopted ASU 2016-02, Leases (Topic 842) (“ASC 842”), as of January 1, 2019. Under ASC 842, the Company determines whether the
arrangement contains a lease at the inception of an arrangement. If a lease is identified in an arrangement, the Company recognizes a right-of-use asset and
liability on its consolidated balance sheet and determines whether the lease should be classified as a finance or operating lease. The Company does not
recognize assets or liabilities for leases with lease terms of less than 12 months.

A lease qualifies as a finance lease if any of the following criteria are met at the inception of the lease: (i) there is a transfer of ownership of the leased

asset to the Company by the end of the lease term, (ii) the Company holds an option to purchase the leased asset that it is reasonably certain to exercise, (iii)
the lease term is for a major part of the remaining

F-14

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

economic life of the leased asset, (iv) the present value of the sum of lease payments equals or exceeds substantially all of the fair value of the leased asset, or
(v) the nature of the leased asset is specialized to the point that it is expected to provide the lessor no alternative use at the end of the lease term. All other
leases are recorded as operating leases.

Finance and operating lease assets and liabilities are recognized at the lease commencement date based on the present value of the lease payments over

the lease term using the discount rate implicit in the lease. If the rate implicit is not readily determinable, the Company utilizes its incremental borrowing rate
at the lease commencement date. Operating lease assets are further adjusted for prepaid or accrued lease payments. Operating lease payments are expensed
using the straight-line method as an operating expense over the lease term. Finance lease assets are amortized to depreciation expense using the straight-line
method over the shorter of the useful life of the related asset or the lease term. Finance lease payments are bifurcated into (i) a portion that is recorded as
imputed interest expense and (ii) a portion that reduces the finance liability associated with the lease.

The Company does not separate lease and non-lease components when determining which lease payments to include in the calculation of its lease assets

and liabilities. Variable lease payments are expensed as incurred. If a lease includes an option to extend or terminate the lease, the Company reflects the option
in the lease term if it is reasonably certain it will exercise the option.

Finance leases are recorded in “Property and equipment, net,” “Other current liabilities” and “Long-term finance lease liabilities” and operating leases are

recorded in “Operating lease assets,” “Other current liabilities” and “Long-term operating lease liabilities” on the Company’s consolidated balance sheet.

In 2018, prior to the adoption of ASC 842 on January 1, 2019, the Company applied build-to-suit accounting and was the deemed owner of its leased

corporate headquarters in Boston and research site in San Diego, for which it was recognizing depreciation expense over the buildings’ useful lives and
imputed interest on the corresponding construction financing lease obligations.

Income Taxes

Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement

carrying amounts and the income tax bases of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on the
available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. On a periodic basis, the Company reassesses the
valuation allowance on its deferred income tax assets weighing positive and negative evidence to assess the recoverability of its deferred tax assets. The
Company includes, among other things, its recent financial performance and its future projections in this periodic assessment.

The Company records liabilities related to uncertain tax positions by prescribing a minimum recognition threshold and measurement attribute for the
financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company does not believe any such
uncertain tax positions currently pending will have a material adverse effect on its consolidated financial statements.

Variable Interest Entities

The Company reviews each collaboration agreement pursuant to which it licenses assets owned by a collaborator in order to determine whether or not it

has a variable interest via the license agreement with the collaborator and if the variable interest is a variable interest in the collaborator as a whole. In
assessing whether the Company has a variable interest in the collaborator as a whole, the Company considers and makes judgments regarding the purpose and
design of the entity, the value of the licensed assets to the collaborator, the value of the collaborator’s total assets and the significant activities of the
collaborator. If the Company has a variable interest in the collaborator as a whole, the Company assesses whether or not the Company is the primary
beneficiary of that VIE based on a number of factors, including (i) which party has the power to direct the activities that most significantly affect the VIE’s
economic performance, (ii) the parties’ contractual rights and responsibilities pursuant to the collaboration agreement and (iii) which party has the obligation
to absorb losses of or the right to receive benefits from the VIE that could be significant to the VIE. If the Company determines it is the primary beneficiary of
a VIE at the onset of the collaboration agreement, the collaboration is treated as a business combination and the Company consolidates the financial
statements of the VIE into the Company’s consolidated financial statements. On a quarterly basis,

F-15

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

the Company evaluates whether it continues to be the primary beneficiary of any consolidated VIEs. If the Company determines that it is no longer the
primary beneficiary of a consolidated VIE, or no longer has a variable interest in the VIE, it deconsolidates the VIE in the period that the determination is
made.

Fair Value of In-process Research and Development Assets and Contingent Payments

The present-value models the Company uses to estimate the fair values of in-process research and development assets and contingent payments pursuant

to collaborations and acquisitions incorporate significant assumptions.

The Company’s discounted cash flow models pertaining to in-process research and development assets include: (i) assumptions regarding the probability
of obtaining marketing approval for a drug candidate; (ii) the timing of and the expected costs to develop and commercialize a drug candidate; (iii) estimates
of future cash flows from potential product sales with respect to a drug candidate; and (iv) appropriate discount and tax rates.

The Company bases its estimates of the probability of achieving the milestones relevant to the fair value of contingent payments, which could include

milestone, royalty and option payments, on industry data. Estimates included in the discounted cash flow models pertaining to contingent payments also
include: (i) estimate regarding the timing of the relevant development and commercial milestones and royalties, (ii) and appropriate discount rates. Please refer
to Note D, “Fair Value Measurements,” for further information.

In-process Research and Development Assets

The Company records the fair value of in-process research and development assets as of the transaction date of a business combination. Each of these
assets is accounted for as an indefinite-lived intangible asset and is maintained on the Company’s consolidated balance sheet until either the project underlying
it is completed or the asset becomes impaired. If the asset becomes impaired or is abandoned, the carrying value of the related intangible asset is written down
to its fair value, and an impairment charge is recorded in the period in which the impairment occurs. If a project is completed, the carrying value of the related
intangible asset is amortized as a part of “Cost of sales” over the remaining estimated life of the asset beginning in the period in which the project is
completed. In-process research and development assets are tested for impairment on an annual basis as of October 1, and more frequently if indicators are
present or changes in circumstances suggest that impairment may exist.

In-process research and development that is acquired in a transaction that does not qualify as a business combination under U.S. GAAP and that does not

have an alternative future use is recorded to “Research and development expenses” in the period in which it is acquired.

Goodwill

The difference between the purchase price and the fair value of assets acquired and liabilities assumed in a business combination is allocated to goodwill.

Goodwill is evaluated for impairment on an annual basis as of October 1, and more frequently if indicators are present or changes in circumstances suggest
that impairment may exist. As noted in Basis of Presentation above, the Company has one operating segment, pharmaceuticals, which is its only reporting
unit.

Deconsolidation

Upon the occurrence of certain events and on a regular basis, the Company evaluates whether it no longer has a controlling interest in its subsidiaries,
including consolidated VIEs. If the Company determines it no longer has a controlling interest, the subsidiary is deconsolidated. The Company records a gain
or loss on deconsolidation based on the difference on the deconsolidation date between (i) the aggregate of (a) the fair value of any consideration received, (b)
the fair value of any retained noncontrolling investment in the former subsidiary and (c) the carrying amount of any noncontrolling interest in the subsidiary
being deconsolidated, less (ii) the carrying amount of the former subsidiary’s assets and liabilities.

Discontinued Operations

The Company assesses whether a deconsolidation is required to be presented as discontinued operations in its consolidated financial statements on the

deconsolidation date. This assessment is based on whether or not the deconsolidation

F-16

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

represents a strategic shift that has or will have a major effect on the Company’s operations or financial results. If the Company determines that a
deconsolidation requires presentation as a discontinued operation on the deconsolidation date, or at any point during the one year period following such date, it
will present the former subsidiary as a discontinued operation in current and comparative period financial statements.

Embedded Derivatives

Embedded derivatives are required to be bifurcated from the host instruments and recorded at fair value if the derivatives are not clearly and closely
related to the host instruments on the date of issuance. The Company did not have any material embedded derivatives that required bifurcation recorded on its
consolidated balance sheets as of December 31, 2020 and 2019, respectively.

Hedging Activities

The Company recognizes the fair value of hedging instruments that are designated and qualify as hedging instruments pursuant to U.S. GAAP, foreign
currency forward contracts, as either assets or liabilities on the consolidated balance sheets. Changes in the fair value of these instruments are recorded each
period in “Accumulated other comprehensive loss” as unrealized gains and losses until the forecasted underlying transaction occurs. Unrealized gains and
losses on these foreign currency forward contracts are included in “Prepaid expenses and other current assets” or “Other assets,” and “Other current liabilities”
or “Other long-term liabilities,” respectively, on the Company’s consolidated balance sheets depending on the remaining period until their contractual
maturity. Realized gains and losses for the effective portion of such contracts are recognized in “Product revenues, net” in the consolidated statement of
operations in the same period that it recognizes the product revenues that were impacted by the hedged foreign exchange rate changes. The Company
classifies the cash flows from hedging instruments in the same category as the cash flows from the hedged items.

Certain of the Company’s hedging instruments are subject to master netting arrangements to reduce the risk arising from such transactions with its
counterparties. The Company presents unrealized gains and losses on its foreign currency forward contracts on a gross basis within its consolidated balance
sheets.

The Company also enters into foreign currency forward contracts with contractual maturities of less than one month designed to mitigate the effect of

changes in foreign exchange rates on monetary assets and liabilities including intercompany balances. These contracts are not designated as hedging
instruments pursuant to U.S. GAAP. Realized gains and losses for such contracts are recognized in “Other income (expense), net” in the consolidated
statement of operations each period.

Restructuring Expenses

The Company records costs and liabilities associated with exit and disposal activities based on estimates of fair value in the period the liabilities are
incurred. The Company’s exit and disposal activities have primarily been associated with the Company’s facilities, but also have included the termination of
employees in some cases. The Company’s initial estimate of its liabilities for net ongoing costs associated with its facility obligations are recorded at fair value
on the cease use date. On a quarterly basis, the Company evaluates and adjusts these liabilities as appropriate for changes in circumstances. Changes to the
Company’s estimate of these liabilities are recorded as additional restructuring expenses (credits). These costs are included in “Restructuring expense
(income)” on the Company’s consolidated statements of operations.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income (loss), which includes foreign currency translation adjustments and
unrealized gains and losses on foreign currency forward contracts and certain marketable securities. For purposes of comprehensive income disclosures, the
Company records provisions for or benefits from income taxes related to the unrealized gains and losses on foreign currency forward contracts and certain
marketable securities. The Company does not record provisions for or benefits from income taxes related to the cumulative translation adjustment, as the
Company intends to permanently reinvest undistributed earnings in its foreign subsidiaries.

Notes to Consolidated Financial Statements (Continued)

Foreign Currency Translation and Transactions

The majority of the Company’s operations occur in entities that have the U.S. dollar denominated as their functional currency. The assets and liabilities of
the Company’s entities with functional currencies other than the U.S. dollar are translated into U.S. dollars at rates of exchange in effect at the end of the year.
Revenue and expense amounts for these entities are translated using the average exchange rates for the period. Net unrealized gains and losses resulting from
foreign currency translation are included in “Accumulated other comprehensive loss.” Net foreign currency exchange transaction losses, which are included in
“Other income (expense), net” on the Company’s consolidated statement of operations, were $16.1 million, $5.2 million and $1.1 million for 2020, 2019 and
2018, respectively. These net foreign currency exchange losses are presented net of the impact of the foreign currency forward contracts designed to mitigate
their effect on the Company’s consolidated statement of operations.

Net Income Per Share Attributable to Vertex Common Shareholders

Basic and diluted net income per share attributable to Vertex common shareholders are presented in conformity with the two-class method required for
participating securities. Shares of unvested restricted stock granted under the Company’s Amended and Restated 2006 Stock and Option Plan had the non-
forfeitable right to receive dividends on an equal basis with other outstanding common stock. As a result, these unvested shares of restricted stock were
considered participating securities under the two-class method. In 2020 and 2019, the Company did not have a significant amount of restricted stock
outstanding under this plan: therefore, the two-class method did not impact its basic and diluted net income per share attributable to Vertex common
shareholders for the years ended December 31, 2020 and 2019.

Under the two-class method, earnings are allocated to (i) Vertex common shares, excluding unvested restricted stock, and (ii) participating securities,
based on their respective weighted-average shares outstanding for the period. Potentially dilutive shares result from the assumed exercise of outstanding stock
options (the proceeds of which are then assumed to have been used to repurchase outstanding stock using the treasury-stock method).

Basic net income per share attributable to Vertex common shareholders is based upon the weighted-average number of common shares outstanding during

the period, excluding restricted stock that had been issued but had not yet vested, if any. Diluted net income per share attributable to Vertex common
shareholders is based upon the weighted-average number of common shares outstanding during the period plus additional weighted-average common
equivalent shares outstanding during the period when the effect is dilutive.

Recently Adopted Accounting Standards

Internal-Use Software

In 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic
350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), which
clarifies the accounting for implementation costs in cloud computing arrangements. ASU 2018-15 became effective on January 1, 2020. The adoption of ASU
2018-15 resulted in an insignificant amount of additional assets recorded on the Company’s consolidated balance sheet.

Fair Value Measurement

In 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair
Value Measurement (“ASU 2018-13”), which modifies the disclosure requirements for fair value measurements. ASU 2018-13 became effective on January 1,
2020. The Company adoption of ASU 2018-13 resulted in additional disclosures related to the Company’s Level 3 inputs. Please refer to Note D, “Fair Value
Measurements,” for further information.

Credit Losses

In 2016, the FASB issued ASU 2016-13, which requires entities to record expected credit losses for certain financial instruments, including trade
receivables, as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. For available-for-sale debt securities in
unrealized loss positions, ASU 2016-13 requires allowances to be

F-18

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

recorded instead of reducing the amortized cost of the investment. ASU 2016-13 became effective on January 1, 2020. The adoption of ASU 2016-13 did not
have a significant impact on the Company’s consolidated financial statements.

Leases

On January 1, 2019, the Company adopted ASC 842 using the modified-retrospective method. Until December 31, 2018, the Company applied build-to-

suit accounting and was the deemed owner of its leased corporate headquarters in Boston and research site in San Diego, for which it was recognizing
depreciation expense over the buildings’ useful lives and imputed interest on the corresponding construction financing lease obligations. Under the amended
guidance that became effective January 1, 2019, the Company accounts for these buildings as finance leases, resulting in increased depreciation expense over
the respective lease terms of approximately 15 years, which are significantly shorter than the buildings’ useful lives of 40 years. The amended guidance also
results in a reduction in imputed interest expense in the initial years of each finance lease term. As of January 1, 2019, the Company recorded a cumulative
effect adjustment to increase its “Accumulated deficit” by $40.3 million related to the adjustments to its build-to-suit leases. Please refer to “Leases” above for
further information.

Revenue Recognition

On January 1, 2018, the Company adopted ASC 606, using the modified retrospective adoption method for all contracts that were not completed as of the

date of adoption. Based on the Company’s review of existing customer contracts as of January 1, 2018, the Company concluded that the only significant
impact that the adoption of ASC 606 had on its consolidated financial statements related to shipments of ORKAMBI under early access programs in France.
Prior to the adoption of ASC 606, the Company did not recognize revenue on the proceeds received from sales of ORKAMBI under early access programs in
France because the price was not fixed or determinable based on the status of ongoing pricing discussions. As of January 1, 2018, the Company recorded a
cumulative effect adjustment to its accumulated deficit of $8.3 million related to the adoption of ASC 606, which primarily represented the Company’s
estimated amount of consideration it expected to retain related to these shipments that would not be subject to a significant reversal in amounts recognized, net
of costs previously deferred related to these shipments.

Equity Investments

On January 1, 2018, the Company adopted ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”),
using the required modified-retrospective adoption method. Under ASU 2016-01, equity investments (except those accounted for under the equity method of
accounting or those that result in consolidation of an investee) are measured at fair value with changes in fair value recognized in net income. As of January 1,
2018, the Company held publicly traded equity investments and equity investments accounted for under the cost method. As a result, in 2018, the Company
recorded a $25.1 million cumulative effect adjustment to “Accumulated deficit” related to its publicly traded equity investments equal to the unrealized gain,
net of tax, that was recorded in “Accumulated other comprehensive loss” as of December 31, 2017.

Recently Issued Accounting Standards

Income Taxes

In 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) (“ASU 2019-12”), which simplifies the accounting for income taxes. ASU 2019-12

was effective on January 1, 2021. The Company does not expect the adoption of ASU 2019-12 to have a significant impact on its consolidated financial
statements.

B. Collaborative Arrangements

The Company has entered into numerous agreements pursuant to which it collaborates with third parties on research, development and commercialization

programs, including in-license and out-license agreements.

In-license Agreements

The Company has entered into a number of license agreements in order to advance and obtain access to technologies and services related to its research

and early-development activities. The Company is generally required to make an upfront payment upon execution of the license agreement; development,
regulatory and commercialization milestones payments upon the achievement of certain product research, development and commercialization objectives; and
royalty payments on future sales, if any, of commercial products resulting from the collaboration.

Pursuant to the terms of its in-license agreements, the Company’s collaborators typically lead the discovery efforts and the Company leads all preclinical,

development and commercialization activities associated with the advancement of any drug candidates and funds all expenses.

The Company typically can terminate its in-license agreements by providing advance notice to its collaborators; the required length of notice is dependent

on whether any product developed under the license agreement has received marketing approval. The Company’s license agreements may be terminated by
either party for a material breach by the other, subject to notice and cure provisions. Unless earlier terminated, these license agreements generally remain in
effect until the date on which the royalty term and all payment obligations with respect to all products in all countries have expired.

CRISPR Therapeutics AG

In 2015, the Company entered into a strategic collaboration, option and license agreement (the “CRISPR Agreement”) with CRISPR Therapeutics AG
and its affiliates (“CRISPR”) to collaborate on the discovery and development of potential new treatments aimed at the underlying genetic causes of human
diseases using CRISPR-Cas9 gene-editing technology. The Company had the exclusive right to license certain targets. In the fourth quarter of 2019, the
Company paid an aggregate of $30.0 million to exclusively license three CRISPR-Cas9-based targets, including CF, pursuant to the CRISPR Agreement. The
Company recorded the $30.0 million total option payment to “Research and development expenses” in the fourth quarter of 2019. For each of the three targets
that the Company elected to license, CRISPR has the potential to receive up to an additional $410.0 million in development, regulatory and commercial
milestones as well as royalties on net product sales.

In 2017, the Company entered into a co-development and co-commercialization agreement with CRISPR pursuant to the terms of the CRISPR
Agreement, under which the Company and CRISPR are co-developing and will co-commercialize CTX001 (the “CTX001 Co-Co Agreement”) for the
treatment of hemoglobinopathies, including treatments for sickle cell disease and beta thalassemia. As part of the collaboration, the Company and CRISPR
share equally all development costs and potential worldwide revenues related to potential hemoglobinopathy treatments. The Company concluded that the
CTX001 Co-Co Agreement is a cost-sharing arrangement, which results in the net impact of the arrangement being recorded in “Research and development
expenses” in its consolidated statements of operations. During the years ended December 31, 2020, 2019 and 2018, the net expense related to the CTX001 Co-
Co Agreement was $50.6 million, $30.1 million and $19.7 million, respectively.

In July 2019, the Company entered into a separate strategic collaboration and license agreement (the “CRISPR DMD/DM1 Agreement”) with CRISPR.

Pursuant to this agreement, the Company received an exclusive worldwide license to CRISPR’s existing and future intellectual property for Duchenne
muscular dystrophy (“DMD”) and myotonic dystrophy type 1 (“DM1”) and the Company made an upfront payment of $175.0 million to CRISPR. The
Company concluded that it did not have any alternative future use for the acquired in-process research and development and recorded the upfront payment to
“Research and development expenses” in the third quarter of 2019. In 2020, the Company recorded $25.0 million to “Research and development expenses”
related to a pre-clinical milestone earned by CRISPR under the CRISPR DMD/DM1 Agreement. CRISPR has the potential to receive up to an additional
$800.0 million in research, development, regulatory and commercial milestones for the DMD and DM1 programs as well as royalties on net product sales.
CRISPR has the option to co-develop and co-commercialize all DM1 products globally and forego the milestones and royalties associated with the

F-20

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

DM1 program. The Company funds all expenses associated with the collaboration except for research costs for specified guide RNA research conducted by
CRISPR, which the Company and CRISPR share equally.

Kymera Therapeutics Inc.

In May 2019, the Company entered into a strategic research and development collaboration agreement with Kymera Therapeutics Inc. (“Kymera”) to
advance small molecule protein degraders against multiple targets. Kymera’s proprietary platform technology is being applied in the collaboration activities in
exchange for an upfront payment of $50.0 million. The Company has the exclusive right to license up to six protein targets, for each of which Kymera may
receive up to $170.0 million in payments, including development, regulatory and commercial milestones as well as royalties on net product sales. In addition
to the upfront payment, the Company purchased $20.0 million of Kymera’s preferred stock. The Company determined that the fair value of its investment in
Kymera’s preferred stock, which did not have a readily determinable fair value, approximated $20.0 million. The preferred stock converted to common stock
when Kymera became a publicly traded company in 2020.

The Company determined that substantially all of the fair value of the Kymera collaboration agreement was attributable to in-process research and
development and no substantive processes were acquired that would constitute a business. The Company concluded that it did not have any alternative future
use for the acquired in-process research and development and recorded the $50.0 million upfront payment to “Research and development expenses” in 2019.

Moderna, Inc.

In 2016, the Company entered into a strategic collaboration and licensing agreement with Moderna, Inc. (“Moderna”), pursuant to which the parties are

seeking to identify and develop messenger ribonucleic acid (“mRNA”) therapeutics for the treatment of CF.

In September 2020, the Company entered into a new strategic collaboration and licensing agreement with Moderna (the “2020 Moderna Agreement”)

aimed at the discovery and development of lipid nanoparticles and mRNAs that can deliver gene-editing therapies to lung cells for the treatment of CF.
Pursuant to the 2020 Moderna Agreement, Moderna received an upfront payment of $75.0 million and is eligible to receive up to $380.0 million in
development, regulatory and commercial milestones as well as royalties on net product sales. The Company determined that substantially all of the fair value
of the 2020 Moderna Agreement was attributable to in-process research and development and no substantive processes were acquired that would constitute a
business. The Company concluded that it did not have any alternative future use for the acquired in-process research and development and recorded the
upfront payment to “Research and development expenses” in the third quarter of 2020.

Other In-License Agreements

In addition to the collaborative arrangements described above, the Company has entered into additional in-license agreements that it does not consider to

be individually significant to its consolidated financial statements. In addition to the payments described above, the Company recorded upfront, option and
milestone payments totaling $84.6 million in 2020, $63.3 million in 2019 and $46.9 million in 2018 to “Research and development expenses” which included
a $40.0 million upfront payment to Skyhawk Therapeutics, Inc. (“Skyhawk”) in 2020.

For Skyhawk and several other in-license agreements that are not individually significant to the Company’s consolidated financial statements, the
Company determined that substantially all of the fair value of each individual agreement was attributable to in-process research and development and no
substantive processes were acquired that would constitute a business. The Company concluded that it did not have any alternative future use for the acquired
in-process research and development associated with the agreements and recorded the related portion of the upfront payments to “Research and development
expenses.” Please refer to Note D, “Fair Value Measurements,” and Note E, “Marketable Securities and Equity Investments,” for further information regarding
the Company’s investments in its collaborators.

Variable Interest Entities (VIEs)

The Company licensed rights to certain drug candidates from these third-party collaborators, which has resulted in the consolidation of the third-parties’

financial statements into the Company’s consolidated financial statements as VIEs for

F-21

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

certain periods of time. Most recently, the Company deconsolidated the financial statements of BioAxone from its consolidated financial statements as of
December 31, 2018. The Company has not consolidated a VIE into its financial statements since December 31, 2018.

BioAxone Biosciences, Inc.

In 2014, the Company entered into a license and collaboration agreement (the “BioAxone Agreement”) with BioAxone, which resulted in the

consolidation of BioAxone as a VIE.

In October 2018, the Company announced it would stop clinical development of VX-210 and terminate the Phase 2b clinical trial of VX-210 based on the

recommendation of the clinical trial’s Data Safety Monitoring Board and the Company’s review of interim data. In December 2018, the Company notified
BioAxone of its intent to terminate the BioAxone Agreement and executed a release that immediately allowed BioAxone to control development of its
neurological programs other than VX-210 without the Company’s consent. As a result of this decision, the Company recorded a $29.0 million impairment
charge related to VX-210 that was attributable to noncontrolling interest.

As a result, the Company deconsolidated BioAxone as of December 31, 2018 because it determined that it no longer was the primary beneficiary of

BioAxone as it no longer had the power to direct the significant activities of BioAxone. The net impact of the deconsolidation was not material to the
Company’s consolidated statement of operations. The Company’s net loss attributable to noncontrolling interest for the year ended December 31, 2018 was
$9.8 million.

Out-license Agreements

The Company has entered into licensing agreements pursuant to which it has out-licensed rights to certain drug candidates to third-party collaborators.
Pursuant to these out-license agreements, the Company’s collaborators become responsible for all costs related to the continued development of such drug
candidates and obtain development and commercialization rights to these drug candidates. Depending on the terms of the agreements, the Company’s
collaborators may be required to make upfront payments, milestone payments upon the achievement of certain product research and development objectives
and may also be required to pay royalties on future sales, if any, of commercial products resulting from the collaboration. The termination provisions
associated with these collaborations are generally the same as those described above related to the Company’s in-license agreements.

Merck KGaA, Darmstadt, Germany

In January 2017, the Company entered into a strategic collaboration and license agreement (the “Oncology Agreement”) with Merck KGaA, Darmstadt,
Germany (the “Licensee”). Pursuant to the Oncology Agreement, the Company granted the Licensee an exclusive worldwide license to research, develop and
commercialize four oncology research and development programs including two clinical-stage programs targeting DNA damage repair: its ataxia
telangiectasia and Rad3-related protein kinase inhibitor program, or ATR program, including VX-970 and VX-803, and its DNA-dependent protein kinase
inhibitor program, or DNA-PK program, including VX-984. In addition, the Company granted the Licensee exclusive, worldwide rights to two pre-clinical
programs.

The Oncology Agreement provided for an upfront payment from the Licensee to the Company of $230.0 million, which was recorded as “Collaborative
and royalty revenues,” under the multiple element arrangement accounting guidance that was applicable in 2017. All of the Company’s activities related to the
Oncology Agreement were substantially complete as of December 31, 2017.

In December 2018, the Company entered into an agreement with Merck KGaA, Darmstadt, Germany (the “DNA-PK Agreement”) whereby the Company

licensed the two lead Vertex DNA-PK compounds from its DNA-PK program for use in the field of gene integration for six specific indications. In exchange
for this exclusive worldwide license to research, develop and commercialize the DNA-PK program for the specified indications within the field of gene
integration, the Company made an upfront payment of $65.0 million. Merck KGaA, Darmstadt, Germany has the potential to receive additional milestones,
primarily related to approval and reimbursement in various markets, as well as royalties on net product sales.

The Company evaluated the DNA-PK Agreement and concluded it represents a modification of the Oncology Agreement pursuant to ASC 606. As of

December 2018, when the Company entered into the DNA-PK Agreement, the Company had

F-22

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

completed its obligations under the Oncology Agreement, but the Oncology Agreement was an open contract pursuant to ASC 606 since the Company could
receive future royalty payments from the commercialization of the licensed programs under the Oncology Agreement.

In applying ASC 606, the Company determined that the license granted under the DNA-PK Agreement is distinct from the license granted by the

Company under the Oncology Agreement since the license to the two lead Vertex DNA-PK compounds is capable of being distinct as the Company is able to
benefit from the license via its ability to internally develop and commercialize the two lead Vertex DNA-PK compounds in the six named indications in the
field of gene-editing, and the license is not dependent on Merck KGaA, Darmstadt, Germany providing any specialized services to the Company. In addition,
the license to the two lead Vertex DNA-PK compounds granted to the Company under the DNA-PK Agreement is distinct from the license granted by the
Company under the Oncology Agreement as the rights conveyed in the licenses differ and both parties have the ability to commercially benefit from the
licenses on their own. Furthermore, the consideration attributable to the license of the two lead Vertex DNA-PK compounds represents fair value. Therefore,
the Company determined it should account for the DNA-PK Agreement as a separate agreement.

The Company determined that substantially all of the fair value of the DNA-PK Agreement was attributable to a single in-process research and
development asset that did not constitute a business. The Company concluded that it did not have any alternative future use for the acquired in-process
research and development and recorded the $65.0 million payment to “Research and development expenses” in 2018 accordingly.

Janssen Pharmaceuticals, Inc.

In 2014, the Company entered into an agreement with Janssen Pharmaceuticals, Inc. (“Janssen”). In the third quarter of 2020, Janssen exercised its right

to terminate its exclusive worldwide license to develop and commercialize certain drug candidates for the treatment of influenza, based on Phase 3 clinical
trial results for pimodivir.

Cystic Fibrosis Foundation

The Company has a research, development and commercialization agreement that was originally entered into in 2004 with the Cystic Fibrosis Foundation,
as successor in interest to the Cystic Fibrosis Foundation Therapeutics, Inc. This agreement was most recently amended in 2016. Pursuant to the agreement, as
amended, the Company agreed to pay royalties ranging from low-single digits to mid-single digits on potential sales of certain compounds first synthesized
and/or tested between March 1, 2014 and August 31, 2016, including elexacaftor, and tiered royalties ranging from single digits to sub-teens on covered
compounds first synthesized and/or tested during a research term on or before February 28, 2014, including KALYDECO (ivacaftor), ORKAMBI (lumacaftor
in combination with ivacaftor) and SYMDEKO/SYMKEVI (tezacaftor in combination with ivacaftor). For combination products, such as ORKAMBI,
SYMDEKO/SYMKEVI and TRIKAFTA/KAFTRIO (elexacaftor/tezacaftor/ivacaftor and ivacaftor), sales are allocated equally to each of the active
pharmaceutical ingredients in the combination product.

C. Earnings Per Share

Basic net income per share attributable to Vertex common shareholders is based upon the weighted-average number of common shares outstanding during

the period. Diluted net income per share attributable to Vertex common shareholders utilizing the treasury-stock method is based upon the weighted-average
number of common shares outstanding during the period plus additional weighted-average common equivalent shares outstanding during the period when the
effect is dilutive.

The fair value of the Company’s financial assets and liabilities reflects the Company’s estimate of amounts that it would have received in connection with
the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In
connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from
sources independent from the Company) and to minimize the use of unobservable inputs (the Company’s assumptions about how market participants would
price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs
used in order to determine the fair value of the Company’s financial assets and liabilities:

Level 1:

Level 2:

Level 3:

Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions
for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or
liabilities and quoted prices for identical assets or liabilities in markets that are not active.
Unobservable inputs based on the Company’s assessment of the assumptions that market participants would use in pricing the asset or
liability.

Notes to Consolidated Financial Statements (Continued)

The Company’s investment strategy is focused on capital preservation. The Company invests in instruments that meet the credit quality standards outlined

in the Company’s investment policy. This policy also limits the amount of credit exposure to any one issue or type of instrument. The Company maintains
strategic investments separately from the investment policy that governs its other cash, cash equivalents and marketable securities as described in Note E,
“Marketable Securities and Equity Investments.” Additionally, the Company utilizes foreign currency forward contracts intended to mitigate the effect of
changes in foreign exchange rates on its consolidated statement of operations.

During the three years ended December 31, 2020, the Company did not record any other-than-temporary impairment charges related to its financial assets.

The following tables set forth the Company’s financial assets and liabilities subject to fair value measurements by level within the fair value hierarchy

Fair Value of Corporate Equity Securities

The Company maintains strategic investments in corporate equity securities separately from the investment policy that governs its other cash, cash
equivalents and marketable securities. The Company classifies its investments in publicly traded companies as “Marketable securities” on its consolidated
balance sheets. Generally, the Company’s investments in the common stock of these publicly traded companies are valued based on Level 1 inputs because
they have readily determinable fair values. However, certain of the Company’s investments in publicly traded companies have been or continue to be valued
based on Level 2 inputs due to transfer restrictions associated with these investments. During the year ended December 31, 2020, the Company transferred the
fair value of one of its strategic investments in a publicly traded company from Level 2 to

F-25

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

Level 1 upon the expiration of transfer restrictions associated with this investment. Please refer to Note E, “Marketable Securities and Equity Investments,” for
further information on these investments.

Fair Value of Contingent Consideration

In 2019, the Company acquired Exonics Therapeutics, Inc. (“Exonics”), a privately-held company focused on creating transformative gene-editing
therapies to repair mutations that cause DMD and other severe neuromuscular diseases, including DM1. The Company’s Level 3 contingent consideration
liabilities are related to $678.3 million of development and regulatory milestones potentially payable to Exonics’ former equity holders. The Company bases
its estimates of the probability of achieving the milestones relevant to the fair value of contingent payments on industry data attributable to rare diseases. The
discount rates used in the valuation model for contingent payments, which were between 0.4% and 1.9% as of December 31, 2020, represent a measure of
credit risk and market risk associated with settling the liabilities. Significant judgment is used in determining the appropriateness of these assumptions at each
reporting period. Due to the uncertainties associated with development and commercialization of drug candidates in the pharmaceutical industry and the
effects of changes in other assumptions including discount rates, the Company expects its estimates regarding the fair value of contingent consideration to
change in the future, resulting in adjustments to the fair value of the Company’s contingent consideration liabilities, and the effect of any such
adjustments could be material.

The following table represents a rollforward of the fair value of the Company’s contingent consideration liabilities:

The “Increase in fair value of contingent payments” in the table above was primarily due to changes in market interest rates.

G. Hedging

Foreign currency forward contracts - Designated as hedging instruments

The Company maintains a hedging program intended to mitigate the effect of changes in foreign exchange rates for a portion of the Company’s forecasted
product revenues denominated in certain foreign currencies. The program includes foreign currency forward contracts that are designated as cash flow hedges
under GAAP having contractual durations from one to eighteen months. The Company recognizes realized gains and losses for the effective portion of such
contracts in “Product revenues, net” in its consolidated statements of operations in the same period that it recognizes the product revenues that were impacted
by the hedged foreign exchange rate changes.

The Company formally documents the relationship between foreign currency forward contracts (hedging instruments) and forecasted product revenues

(hedged items), as well as the Company’s risk management objective and strategy for undertaking various hedging activities, which includes matching all
foreign currency forward contracts that are designated as cash flow hedges to forecasted transactions. The Company also formally assesses, both at the hedge’s
inception and on an ongoing basis, whether the foreign currency forward contracts are highly effective in offsetting changes in cash flows of hedged items on
a prospective and retrospective basis. If the Company were to determine that a (i) foreign currency forward contract is not highly effective as a cash flow
hedge, (ii) foreign currency forward contract has ceased to be a highly effective hedge or (iii) forecasted transaction is no longer probable of occurring, the
Company would discontinue hedge accounting treatment prospectively. The Company measures effectiveness based on the change in fair value of the forward
contracts and the fair value of the hypothetical foreign currency forward contracts with terms that match the critical terms of the risk being hedged. As of
December 31, 2020, all hedges were determined to be highly effective.

F-28

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

Prior to the adoption of ASU 2017-12 on January 1, 2019, the Company did not record any ineffectiveness related to its foreign currency forward

contracts that were designated as hedging instruments in the year ended December 31, 2018. ASU 2017-12 eliminated the requirement to separately measure
and report hedge ineffectiveness.

The Company considers the impact of its counterparties’ credit risk on the fair value of the foreign currency forward contracts. As of December 31,

2020 and December 31, 2019, credit risk did not change the fair value of the Company’s foreign currency forward contracts.

flow hedges under U.S. GAAP:

The Company also enters into foreign currency forward contracts with contractual maturities of less than one month that are designed to mitigate the
effect of changes in foreign exchange rates on monetary assets and liabilities, including intercompany balances. These contracts are not designated as hedging
instruments under U.S. GAAP. The Company recognizes realized gains and losses for such contracts in “Other income (expense), net” in its consolidated
statements of operations each period. As of December 31, 2020, the notional amount of the Company’s outstanding foreign currency forward contracts where
hedge accounting under U.S. GAAP is not applied was $198.9 million.

L. Leases

Finance Leases

The Company’s finance lease assets and liabilities primarily relate to its corporate headquarters in Boston and research site in San Diego (the
“Buildings”). These Buildings are classified as finance leases because the present value of the sum of the lease payments associated with the Buildings
exceeds substantially all of the fair value of the Buildings. The Company also has outstanding finance leases for equipment and land.

Pursuant to ASC 842, which was adopted on January 1, 2019, the Company’s finance lease assets are amortized to depreciation expense using the
straight-line method over the remaining lease term; and the Company records imputed interest expense associated with its finance lease liabilities. In 2018,
prior to the adoption of ASC 842, the Company applied build-to-

F-32

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

suit accounting and was deemed for accounting purposes to be the owner of the Buildings, for which it recognized depreciation expense over the Buildings 40
years useful lives and imputed interest expense on the corresponding financing lease obligations.

Corporate Headquarters

In 2011, the Company entered into two lease agreements, pursuant to which the Company leases approximately 1.1 million square feet of office and
laboratory space in two buildings in Boston, Massachusetts for a term of 15 years. Base rent payments commenced in December 2013, and will continue
through December 2028. The Company utilizes this initial period as its lease term. The Company has an option to extend the lease term for an additional ten
years.

San Diego Lease

In 2015, the Company entered into a lease agreement pursuant to which the Company leases approximately 170,000 square feet of office and laboratory

space in San Diego, California for a term of 16 years. Base rent payments commenced in the second quarter of 2019, and will continue through May 2034.
The Company utilizes this initial period as its lease term. The Company has an option to extend the lease term for up to two additional five-year terms. The
Company placed this building into service in the second quarter of 2018.

Operating Leases

The Company’s operating leases relate to its real estate leases that are not classified as finance leases.

Cell and Genetic Therapies Lease

In 2019, the Company entered into an agreement to lease approximately 269,000 square feet of office and laboratory space near its corporate headquarters

in Boston, Massachusetts. The lease agreement includes an initial term of 15 years plus a period to install leasehold improvements, with an option to extend
the lease term for up to two additional ten-year periods. Base rent payments will commence in the fourth quarter of 2021. The Company has utilized the initial
period, which commenced in the third quarter of 2020 upon occupation of the building, as its lease term. As of December 31, 2020, the Company recorded a

Program for an aggregate of $75.1 million including commissions and fees. The Company expects to fund further repurchases of its common stock through a
combination of cash on hand and cash generated by operations. As of December 31, 2020, there was a total of $424.9 million remaining for repurchases of its
common stock under the 2020 Share Repurchase Program.

Under the 2020 Share Repurchase Program, the Company is authorized to purchase shares from time to time through open market or privately negotiated

Stock and Option Plans

The purpose of each of the Company’s stock and option plans is to attract, retain and motivate its employees, consultants and directors. Awards granted

under these plans can be nonstatutory stock options (“NSOs”), incentive stock options (“ISOs”), restricted stock units (“RSUs”) including performance-based
RSUs (“PSUs”), restricted stock (“RSs”), or other equity-based awards, as specified in the individual plans.

Shares issued under all of the Company’s plans are funded through the issuance of new shares. The following table contains information about the

All options granted under the Company’s 2013 Stock and Option Plan (“2013 Plan”) and 2006 Stock and Option Plan (“2006 Plan”) were granted with an

exercise price equal to the fair value of the underlying common stock on the date of grant. As of December 31, 2020, the stock and option plan under which
the Company is authorized to make new equity awards is the Company’s 2013 Plan. Under the 2013 Plan, no stock options can be awarded with an exercise
price less than the fair market value on the date of grant. In 2019 and 2018, the Company’s shareholders approved increases in the number of shares
authorized for issuance pursuant to the 2013 Stock and Option Plan of (i) 5,000,000 shares in 2019 and (ii) 8,000,000 shares in 2018.

During the three years ended December 31, 2020, grants to current employees and directors primarily had a grant date that was the same as the date the
award was approved by the Company’s Board of Directors. During the three years ended December 31, 2020, for grants to new employees and directors, the
date of grant for awards was the employee’s first day of employment or the date the director was elected to the Company’s Board of Directors. All options
awarded under the Company’s stock and option plans expire not more than 10 years from the grant date.

Performance-based RSUs (PSUs)

The potential range of shares issuable pursuant to the Company’s PSU awards range from 0% to 200% of the target shares based on financial and non-

financial measures. Fifty percent of PSUs that could be earned have a one-year performance period with the amount actually earned dependent upon the
Company’s financial performance and with vesting of the earned shares in three equal installments over a three-year period. The remaining 50% of PSUs that
could be earned have a three-year performance period with the amount actually earned dependent upon the achievement of multiple clinical development
milestones and with the earned shares cliff vesting at the end of the three-year performance period.

Employee Stock Purchase Plan

The Company has an employee stock purchase plan (the “ESPP”). The ESPP permits eligible employees to enroll in a twelve-month offering period
comprising two six-month purchase periods. Participants may purchase shares of the Company’s common stock, through payroll deductions, at a price equal
to 85% of the fair market value of the common stock on the first day of the applicable twelve-month offering period, or the last day of the applicable six-
month purchase period,

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

whichever is lower. Purchase dates under the ESPP occur on or about May 14 and November 14 of each year. As of December 31, 2020, there were 1,996,321
shares of common stock authorized for issuance pursuant to the ESPP.

In 2020, the following shares were issued to employees under the ESPP:

The Company has a 401(k) retirement plan (the “Vertex 401(k) Plan”) in which substantially all of its permanent U.S. employees are eligible to

participate. Participants may contribute up to 60% of their annual compensation to the Vertex 401(k) Plan, subject to statutory limitations. The Company may
declare discretionary matching contributions to the Vertex 401(k) Plan. The Company pays matching contributions in the form of cash. For the years ended
December 31, 2020, 2019 and 2018, the Company contributed approximately $19.2 million, $15.8 million and $13.9 million to the plan, respectively.

N. Stock-based Compensation Expense

The Company recognizes share-based payments to employees as compensation expense using the fair value method. The fair value of stock options and

shares purchased pursuant to the ESPP is calculated using the Black-Scholes option pricing model. The fair value of restricted stock units, including PSUs,
and restricted stock is based on the intrinsic value on the date of grant. Stock-based compensation, measured at the grant date based on the fair value of the
award, is typically recognized as expense ratably over the requisite service period.

The effect of stock-based compensation expense during the three years ended December 31, 2020 was as follows:

Stock-based compensation expense by line item:

Research and development expenses
Sales, general and administrative expenses

In each of the three years ended December 31, 2020, the Company issued stock options to its non-employee directors. In 2019 and 2018, the Company

issued stock options with service conditions, which were generally the vesting periods of the awards, to its employees. The Company uses the Black-Scholes
option pricing model to estimate the fair value of stock options at the grant date. The Black-Scholes option pricing model uses the option exercise price as well
as estimates and assumptions related to the expected price volatility of the Company’s stock, the rate of return on risk-free investments, the expected period
during which the options will be outstanding, and the expected dividend yield for the Company’s stock to estimate the fair value of a stock option on the grant
date. The options granted during 2020, 2019 and 2018 had a weighted-average grant-date fair value per share of $88.37, $61.32 and $60.83, respectively.

The fair value of each option granted during 2020, 2019 and 2018 was estimated on the date of grant using the Black-Scholes option pricing model with

the following weighted-average assumptions:

Stock options granted

Expected stock price volatility
Risk-free interest rate
Expected term of options (in years)
Expected annual dividends

40.50%
2.61%

—

The weighted-average valuation assumptions were determined as follows:

•

•

•

•

Expected stock price volatility: Expected stock price volatility is calculated using the trailing one-month average of daily implied volatilities prior to
the grant date. Implied volatility is based on options to purchase the Company’s stock with remaining terms of greater than one year that are regularly
traded in the market.

Risk-free interest rate: The Company bases the risk-free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time of
grant for a period that is commensurate with the assumed expected option term.

Expected term of options: The expected term of options represents the period of time options are expected to be outstanding. The Company uses
historical data to estimate employee exercise and post-vest termination behavior. The Company believes that all groups of employees exhibit similar
exercise and post-vest termination behavior and therefore does not stratify employees into multiple groups in determining the expected term of
options.

Expected annual dividends: The estimate for annual dividends is $0.00 because the Company has not historically paid, and does not intend for the
foreseeable future to pay, a dividend.

The Company awards restricted stock units with service conditions, which are generally the vesting periods of the awards. As of December 31, 2020, the

Company did not have any unvested restricted stock awards remaining, which it awarded until 2016.

The Company grants PSUs to certain members of senior management. Half of the PSUs contain financial goals as the performance metric and the other
half contain non-financial goals. A target number of shares is established for each award, however the actual number of shares that are issued when an award
vests may range from zero to 200% of the target amount depending upon the level of achievement of the applicable performance metric. The financial-based
PSUs vest in three equal installments over a three-year period and are expensed ratably over that same period based upon an assessment of the likely level of
achievement. The non-financial based PSUs cliff vest at the end of the three-year performance period and are expensed on a straight-line basis over that same
period based upon an assessment of the likely level of achievement.

Employee Stock Purchase Plan

The weighted-average fair value of each purchase right granted during 2020, 2019 and 2018 was $65.88, $47.79 and $44.04, respectively. The following

table reflects the weighted-average assumptions used in the Black-Scholes option pricing model for 2020, 2019 and 2018:

Expected stock price volatility
Risk-free interest rate
Expected term (in years)
Expected annual dividends

33.43%
2.08%
0.74
—

2018
36.51%
2.36%

—

The expected stock price volatility for ESPP offerings is based on implied volatility. The Company bases the risk-free interest rate on the interest rate

payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected term. The expected term
represents purchases and purchase periods that take place within the offering period. The expected annual dividends estimate is $0.00 because the Company
has not historically paid, and does not for the foreseeable future intend to pay, a dividend.

The Company is subject to U.S. federal, state, and foreign income taxes. The Company’s provision for income taxes during the years ended December 31,

2020 and 2019, has increased compared to historical amounts due to the release of the Company’s valuation allowance on the majority of its net operating
losses (“NOLs”) and other deferred tax assets as of December 31, 2018. Starting in 2019, the Company began recording a provision for income taxes
approximating the statutory rates on its pre-tax income. The Company’s effective tax rate of 13% for 2020 was lower than the U.S. statutory rate primarily due
to (i) discrete tax benefits associated with an intra-entity transfer of intellectual property rights to the United Kingdom (“U.K.”), the write-off of a long-term
intercompany receivable, and an increase in the U.K.’s corporate tax rate; and (ii) excess tax benefits related to stock-based compensation. The impact of these
items was partially offset by a U.S. deemed dividend. The Company’s effective tax rate of 16% for 2019 was lower than the U.S. statutory rate primarily due
to excess tax benefits related to stock-based compensation and research and development tax credits. The Company utilized substantially all of its remaining
previously benefited U.S. NOLs in 2020. As a result, a larger portion of the Company’s tax provision will represent a cash tax payable in future periods.

F-42

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

In the second quarter of 2020, the Company completed an intra-entity transfer of intellectual property rights to the U.K., resulting in a deferred tax benefit

of $209.0 million. The Company expects to be able to utilize the deferred tax asset resulting from the intra-entity transfer.

In 2018, the change in the “Benefit from income taxes attributable to valuation allowances” was primarily related to the release of the Company’s
valuation allowances on the majority of its NOLs and other deferred tax assets related to the U.S. and the U.K. The Company released these valuation
allowances after determining it was more likely than not that its deferred tax assets would be realized in the future based on positive evidence, including
significant cumulative consolidated and U.S. income over the three years ended December 31, 2018, revenue growth, clinical trial data from the Company’s
triple combination regimens, competitor clinical progress and expectations regarding future profitability, and negative evidence, including the potential impact
of competition on the Company’s projections and cumulative losses in one of the jurisdictions.

Deferred tax assets and liabilities are determined based on the difference between financial statement and tax bases using enacted tax rates in effect for the

year in which the differences are expected to reverse. The components of the deferred taxes were as follows:

Deferred tax assets:

Net operating loss
Tax credit carryforwards
Intangible assets
Deferred revenues
Stock-based compensation
Accrued expenses
Finance lease liabilities
Operating lease assets
Other

Gross deferred tax assets
Valuation allowance
Total deferred tax assets
Deferred tax liabilities:

Property and equipment
Acquired intangibles
Unrealized gain
Operating lease liabilities
Other

Net deferred tax assets

On a periodic basis, the Company reassesses the valuation allowance on its deferred income tax assets, weighing positive and negative evidence to assess
the recoverability of the deferred tax assets. As of December 31, 2020, the Company maintained a valuation allowance of $213.8 million related primarily to
U.S. state and foreign tax attributes.

As of December 31, 2020, the Company had NOL carryforwards of $97.4 million, which are subject to annual utilization limitations, and tax credits of
$249.2 million for U.S. federal income tax purposes. As of December 31, 2020, the Company had NOL carryforwards of $708.2 million and tax credits of
$179.1 million for U.S. state income tax purposes. The U.S. federal NOLs may be carried forward indefinitely, with the exception of $29.1 million that will
begin to expire in 2030. The state NOL carryforwards and tax credits expire at various dates through 2040 and may be used to offset future state income tax
liabilities. As of December 31, 2020, the Company had foreign net operating loss carryforwards of $521.6 million, including $10.6 million that were subject to
expiration at various dates through 2040 and $511.0 million that had an indefinite carryforward period.

As of December 31, 2020, the Company has classified $48.1 million and $38.5 million of its unrecognized tax benefits as credits to “Deferred tax assets”

and “Accrued expenses,” respectively, on its consolidated balance sheet.

The Company has reviewed the tax positions taken, or to be taken, in its tax returns for all tax years currently open to examination by a taxing authority.

Unrecognized tax benefits represent the aggregate tax effect of differences between tax return positions and the benefits recognized in the consolidated
financial statements. As of December 31, 2020, 2019 and 2018, the Company had $75.8 million, $33.9 million and $19.5 million, respectively, of net
unrecognized tax benefits, which would affect the Company’s tax rate if recognized. The Company does not expect that its unrecognized tax benefits will
materially change within the next twelve months. The Company accrues interest and penalties related to unrecognized tax benefits as a component of its
“Provision for (benefit from) income taxes.” The Company did not recognize any material interest or penalties related to uncertain tax positions during the
three years ended December 31, 2020.

In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act includes provisions

relating to several aspects of corporate income taxes. The CARES Act did not have a significant impact on the Company’s provision for income taxes.

As of December 31, 2020, foreign earnings, which were not significant, have been retained by the Company’s foreign subsidiaries for indefinite
reinvestment. Upon repatriation of those earnings, in the form of dividends or otherwise, the Company could be subject to withholding taxes payable to the
various foreign countries.

The Company files U.S. federal income tax returns and income tax returns in various state, local and foreign jurisdictions. The Company is no longer

subject to any tax assessment from an income tax examination in the U.S. or any other major taxing jurisdiction for years before 2011, except where the
Company has NOLs or tax credit carryforwards that originate before 2011. The Company has various income tax audits ongoing at any time throughout the
world.

P. Commitments and Contingencies

Revolving Credit Facilities

The Company and certain of its subsidiaries have entered into two credit agreements (the “Credit Agreements”) with Bank of America, N.A., as
administrative agent and the lenders referred to therein (the “Lenders”). The Credit Agreements were not drawn upon at closing and the Company has not
drawn upon them to date. Amounts drawn pursuant to the Credit Agreements, if any, will be used for general corporate purposes. Any amounts borrowed
under the Credit Agreements will bear interest, at the Company’s option, at either a base rate or a Eurocurrency rate, in each case plus an applicable margin
based on the Company’s consolidated leverage ratio (the ratio of the Company’s total consolidated funded indebtedness to the Company’s consolidated
EBITDA for the most recently completed four fiscal quarter period).

In September 2019, the Company and certain of its subsidiaries entered into a $500.0 million unsecured revolving facility (the “2019 Credit Agreement”)

with the Lenders, which matures on September 17, 2024. The 2019 Credit Agreement superseded the Company’s credit agreement entered into in 2016 with
Bank of America, N.A serving in the same capacity. Under the 2019 Credit Agreement, the applicable margins on base rate loans range from 0.125% to
0.500% and the

F-44

VERTEX PHARMACEUTICALS INCORPORATED

Notes to Consolidated Financial Statements (Continued)

applicable margins on Eurocurrency loans range from 1.125% to 1.500%. The 2019 Credit Agreement provides a sublimit of $50.0 million for letters of credit.

In September 2020, the Company and certain of its subsidiaries entered into a $2.0 billion unsecured revolving facility (the “2020 Credit Agreement”)

with the Lenders, which matures on September 18, 2022. Under the 2020 Credit Agreement, the applicable margins on base rate loans range from 0.500% to
0.875% and the applicable margins on Eurocurrency loans range from 1.500% to 1.875%. The 2020 Credit Agreement does not support the issuance of letters
of credit.

Subject to satisfaction of certain conditions, the Company may request that the borrowing capacity for each of the Credit Agreements be increased by an

additional $500.0 million. Any amounts borrowed pursuant to the Credit Agreements are guaranteed by certain of the Company’s existing and future domestic
subsidiaries, subject to certain exceptions.

The Credit Agreements contain customary representations and warranties and affirmative and negative covenants, including financial covenants to

maintain (x) subject to certain limited exceptions, a consolidated leverage ratio of 3.50 to 1.00, subject to an increase to 4.00 to 1.00 following a material
acquisition and (y) a consolidated interest coverage ratio of 2.50 to 1.00, in each case measured on a quarterly basis. As of December 31, 2020, the Company
was in compliance with the covenants described above. The Credit Agreements also contain customary events of default. In the case of a continuing event of
default, the administrative agent would be entitled to exercise various remedies, including the acceleration of amounts due under outstanding loans.

Direct costs related to the Credit Agreements, which were not material to the Company’s financial statements, were deferred and recorded over the term

of the Credit Agreements.

Guaranties and Indemnifications

As permitted under Massachusetts law, the Company’s Articles of Organization and By-laws provide that the Company will indemnify certain of its
officers and directors for certain claims asserted against them in connection with their service as an officer or director. The maximum potential amount of
future payments that the Company could be required to make under these indemnification provisions is unlimited. However, the Company has purchased
directors’ and officers’ liability insurance policies that could reduce its monetary exposure and enable it to recover a portion of any future amounts paid. No
indemnification claims currently are outstanding, and the Company believes the estimated fair value of these indemnification arrangements is minimal.

The Company customarily agrees in the ordinary course of its business to indemnification provisions in agreements with clinical trial investigators and

sites in its drug development programs, sponsored research agreements with academic and not-for-profit institutions, various comparable agreements
involving parties performing services for the Company, and its real estate leases. The Company also customarily agrees to certain indemnification provisions
in its drug discovery, development and commercialization collaboration agreements. With respect to the Company’s clinical trials and sponsored research
agreements, these indemnification provisions typically apply to any claim asserted against the investigator or the investigator’s institution relating to personal
injury or property damage, violations of law or certain breaches of the Company’s contractual obligations arising out of the research or clinical testing of the
Company’s compounds or drug candidates. With respect to lease agreements, the indemnification provisions typically apply to claims asserted against the
landlord relating to personal injury or property damage caused by the Company, to violations of law by the Company or to certain breaches of the Company’s
contractual obligations. The indemnification provisions appearing in the Company’s collaboration agreements are similar to those for the other agreements
discussed above, but in addition provide some limited indemnification for its collaborator in the event of third-party claims alleging infringement of
intellectual property rights. In each of the cases above, the indemnification obligation generally survives the termination of the agreement for some extended
period, although the Company believes the obligation typically has the most relevance during the contract term and for a short period of time thereafter. The
maximum potential amount of future payments that the Company could be required to make under these provisions is generally unlimited. The Company has
purchased insurance policies covering personal injury, property damage and general liability that reduce its exposure for indemnification and would enable it
in many cases to recover all or a portion of any future amounts paid. The Company has never paid any material amounts to defend lawsuits or settle claims
related to these indemnification provisions. Accordingly, the Company believes the estimated fair value of these indemnification arrangements is minimal.

Other Contingencies

The Company has certain contingent liabilities that arise in the ordinary course of its business activities. The Company accrues a reserve for contingent

liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. There were no material contingent
liabilities accrued as of December 31, 2020 or 2019.

1.82.    “Net Sales” means the gross invoiced price for Shared Products sold by a Party or its Affiliates (the “Selling Party”)

to Third Parties, less the following deductions from such gross amounts:

(a)    [***];

(b)    [***];

(c)    [***];

(d)    [***];

(e)    [***].

Generally, only items that are deducted from the Selling Party’s gross invoiced sales price of Shared Product(s), as
included in the Selling Party’s published financial statements and that are in accordance with GAAP, applied on a
consistent basis, will be deducted from such gross invoiced sales price for purposes of the calculation of Net Sales.
However, compulsory payments required by federal or state governments based upon sales volume or market share
of  Shared  Products  (but  for  clarity  excluding  taxes  on  the  Selling  Party’s  net  income),  to  the  extent  borne  by  the
Selling  Party,  will  be  deducted  from  “Net  Sales”  regardless  of  its  classification  in  the  Selling  Party’s  published
financial  statements;  provided  that  any  such  deduction  will  be  limited  to  that  share  of  such  compulsory  payment
proportional  to  the  share  of  the  total  sales  volume  or  market  share  of  the  Selling  Party  used  to  compute  the
compulsory payment represented by applicable Net Sales of Shared Products.

A qualifying amount may be deducted only once regardless of the number of the preceding categories that describe
such amount. If a Selling Party makes any adjustment to such deductions after the associated Net Sales have been
reported  pursuant  to  this  Agreement,  the  adjustments  will  be  reported  with  the  next  Summary  Statement.  Sales
between or among a Party, its Affiliates and Sublicensees will be excluded from the computation of Net Sales if such
sales are not intended for end use, but Net Sales will include the subsequent final sales to Third Parties by a Party or
any  such  Affiliates  or  Sublicensees.  A  Shared  Product  will  not  be  deemed  to  be  sold  if  the  Shared  Product  is
provided  free  of  charge  to  a  Third  Party  in  reasonable  quantities  as  a  sample  consistent  with  industry  standard
promotional and sample practices. [***].

If a sale, transfer or other disposition with respect to Shared Products involves consideration other than cash or is not
at arm’s length, then the Net Sales from such sale, transfer or other disposition will be calculated on the [***].

Solely for purposes of calculating Net Sales, if a Party or its Affiliates or any permitted Sublicensee sells a Shared
Product in the form of a combination product

containing a Shared Product and one or more other therapeutically or prophylactically active ingredients or delivery
devices (whether combined in a single formulation or package, as applicable, or formulated separately but packaged
under  a  single  label  approved  by  a  Regulatory  Authority  and  sold  together  for  a  single  price)  (a  “Combination
Product”),  Net  Sales  of  such  Combination  Product  will  be  calculated  by  multiplying  actual  Net  Sales  of  such
Combination Product as determined in the first paragraph of the definition of “Net Sales” by the fraction A/(A+B)
where  [***].  The  weighted  average  invoice  prices  referenced  above  will  be  calculated  with  reference  to  the
prevailing prices during the applicable Calendar Quarter in those top selling countries that equate to [***]% of Net
Sales  of  the  applicable  Shared  Product  in  the  Territory,  with  the  prices  weighted  in  the  calculation  to  reflect  the
actual relative sales value of the Shared Product in each of the countries to which the calculation relates. If it is not
possible to determine the fraction A/(A+B) based on the criteria specified in the preceding sentence (e.g., if a Shared
Product  component  is  not  sold  separately),  the  Parties  shall  determine  Net  Sales  for  the  Shared  Product  in  such
Combination Product in good faith by mutual agreement [***].

will  maintain  the  books  and  records  referred  to  in  Section  7.8.  Each  Party  will  accrue  all  Program  Expenses,
Sublicense  Revenue  and  Net  Sales  in  accordance  with  the  terms  and  conditions  hereof  and  in  accordance  with
GAAP, provided that all Out-of-Pocket Costs under this Agreement will be deemed accrued at the time of invoice for
purposes of the calculation and reconciliation of Net Profit or Net Loss under this Agreement. Within [***] Business
Days after the end of each Calendar Quarter, each Party will submit to the other a written report reflecting the accrual
of Program Expenses, Sublicense Revenue and Net Sales during the just-ended Calendar Quarter, except that each
Party’s submission for the last month of such Calendar Quarter will be a good faith estimate and not actual amounts
(each, a “Summary Statement”). Within [***] days after the end of each Calendar Quarter, each Party will submit
to the other an updated Summary Statement reflecting the actual accrual of Program Expenses, Sublicense Revenue
and Net Sales for the last month of such Calendar Quarter, which Summary Statement will be certified as true and
accurate  by  a  representative  of  such  Party  that  is  a  Vice  President  of  Finance  or  more  senior  representative.  Each
Summary  Statement  (after  the  initial  Summary  Statement)  will  reflect  an  adjustment  for  the  actual  amount  of  the
previous Calendar Quarter as needed, provided that, if, prior to preparation of a Summary Statement in accordance
with the preceding sentence, a Party discovers that actual Program Expenses, Sublicense Revenue or Net Sales have
deviated  materially  from  any  non-binding,  good  faith  estimate  of  such  Program  Expenses,  Sublicense  Revenue  or
Net  Sales  submitted  to  the  other  Party  in  accordance  with  this  Section  7.5  (including  any  deviation  in  any  single
Expense or in aggregate Sublicense Revenue or aggregate Net Sales, in each case, of more than $[***]), then such
Party  shall  promptly  notify  the  other  Party  of  such  deviation  in  advance  of  delivery  of  such  Summary  Statement.
Any reporting and reconciliation of variances between estimated and actual Expenses may be delayed by a Calendar
Quarter as reasonably necessary in light of a Party’s internal reporting procedures. The Parties’ respective Summary
Statements  will  serve  as  the  basis  of  the  Reconciliation  Reports  prepared  by  [***]  pursuant  to  Section  7.6.  The
Parties’ respective finance departments, coordinated by the JDC, or JCC, as appropriate, will meet at least once per
[***], or as otherwise mutually agreed by the Parties, to discuss any questions or issues arising from the Summary
Statements,  including  the  basis  for  the  accrual  of  specific  Program  Expenses,  review  budgets  and  forecasts,  and
discuss reconciliation and reporting procedures.

7.6.    Reconciliation. [***] will prepare a  reconciliation  report,  as  soon  as  practicable  after  the  receipt of [***] updated
Summary  Statement,  but  in  any  event  within  [***]  days  after  the  end  of  each  Calendar  Quarter,  accompanied  by
reasonable supporting documents and calculations sufficient to support each Party’s financial reporting obligations,
independent  auditor  requirements  and  obligations  under  the  Sarbanes-Oxley  Act,  which  reconciles  the  amounts
accrued  and  reported  in  each  Party’s  Summary  Statement  during  such  Calendar  Quarter  and  the  share  of  the  Net
Profits and Net Losses to be allocated to each of the Parties for such Calendar Quarter in accordance with Section 7.3
(such report, the “Reconciliation

subject of a conviction described in Section 306 of the FD&C Act, or if any action, suit, claim, investigation
or  legal  or  administrative  proceeding  is  pending  or,  to  Vertex’s  knowledge,  is  threatened,  relating  to  the
debarment or conviction of CRISPR, any of its Affiliates or any such Person performing services hereunder
or thereunder.

12.5.    Disclaimer. Except as otherwise  expressly  set  forth  in  this  Agreement,  neither  Party  nor  its Affiliates makes any
representation  or  extends  any  warranty  of  any  kind,  either  express  or  implied,  including  any  warranty  of
merchantability or fitness for a particular purpose. Vertex and CRISPR understand that each Product is the subject of
ongoing  Research  and  Development  and  that  neither  Party  can  assure  the  safety,  usefulness  or  commercial  or
technical viability of any Product.

12.6.    [***]. Notwithstanding anything to the contrary in this Agreement, if it is [***] that [***] has [***] (a “[***]”), then

INDEMNIFICATION; INSURANCE

13.1.    Indemnification by Vertex. Vertex will indemnify, defend and hold harmless each CRISPR Indemnified Party from
and against any and all Liability that the CRISPR Indemnified Party may be required to pay to one or more Third
Parties to the extent resulting from or arising out of:

50

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

13.1.1.    [***];

13.1.2.    [***];

except, in each case, to the extent CRISPR is required to indemnify Vertex pursuant to Section 13.2.

13.2.    Indemnification by CRISPR. Each CRISPR Entity will jointly and severally indemnify, defend and hold harmless
each  Vertex  Indemnified  Party  from  and  against  any  and  all  Liabilities  that  the  Vertex  Indemnified  Party  may  be
required to pay to one or more Third Parties to the extent resulting from or arising out of:

13.2.1.    [***];

13.2.2.    [***];

except, in each case, to the extent Vertex is required to indemnify CRISPR pursuant to Section 13.1.

13.3.        Procedure.  Each  Party  will  notify  the  other  Party  in  writing  if  it  becomes  aware  of  a  claim  for  which
indemnification may be sought hereunder. In case any proceeding (including any governmental investigation) will be
instituted involving any Indemnified Party, such Indemnified Party will give prompt written notice of the indemnity
claim to the Indemnifying Party and provide a copy to the Indemnifying Party of any complaint, summons or other
written  or  verbal  notice  that  the  Indemnified  Party  receives  in  connection  with  any  such  claim.  An  Indemnified
Party’s failure to deliver written notice will relieve the Indemnifying Party of liability to the Indemnified Party under
this  ARTICLE  13  only  to  the  extent  such  delay  is  prejudicial  to  the  Indemnifying  Party’s  ability  to  defend  such
claim. Provided that the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party will
permit the Indemnifying Party to control any litigation relating to such claim and the disposition of such claim by
negotiated  settlement  or  otherwise  and  any  failure  to  contest  prior  to  assuming  control  will  be  deemed  to  be  an
admission of the obligation to indemnify. The Indemnifying Party will act reasonably and in good faith with respect
to  all  matters  relating  to  such  claim  and  will  not  settle  or  otherwise  resolve  such  claim  without  the  Indemnified
Party’s  prior  written  consent,  which  will  not  be  withheld,  delayed  or  conditioned  unreasonably,  other  than
settlements  only  involving  the  payment  of  monetary  awards  for  which  the  Indemnifying  Party  will  be  fully-
responsible. The Indemnified Party will cooperate with the Indemnifying Party in such Party’s defense of any claim
for which indemnity is sought under this Agreement, at the Indemnifying Party’s sole cost and expense.

13.4.    Other Third Party Claims. If a Third Party brings a claim of any nature arising out of [***] other than [***], the

[***] will [***]. [***] will [***]. The [***] will [***]. The [***]. If [***].

13.5.    Insurance.

13.5.1.    Coverage.  From  and  after  the  Effective  Date,  each  Party  will,  at  its  sole  cost  and  expense,  procure  and
maintain  the  following  policies,  each  naming  the  other  Party  and  its  Indemnified  Parties  as  additional
insureds:

(a)    [***] in amounts not less than $[***] annual aggregate;

(b)    [***] coverage in amounts not less than $[***];

(c)    [***] in amounts not less than $[***] per incident and $[***] annual aggregate, which policy shall

include [***], as applicable, and for [***]; and

(d)    [***] (also called [***]) in amounts not less than $[***] per claim and annual aggregate, covering

[***].

Each such policy will be [***].

13.5.2.    Evidence of Insurance. Each Party will provide the other Party with evidence of the insurance required
under this Section 13.5 upon the other Party’s request. Each Party will provide the other Party with notice at
least 30 days prior to the cancellation, non-renewal or material change in such insurance. The cancelling or
non-renewing  Party  will  obtain  replacement  insurance  providing  comparable  coverage  prior  to  the
expiration of such 30-day period.

13.5.3.    Post-Termination Obligations.  Each  Party  will  maintain  the  insurance  required  under  this  Section  13.5
beyond  the  expiration  or  termination  of  this  Agreement  for  a  reasonable  period  after  the  period  during
which either Party or its Affiliates or Sublicensees is Developing or Commercializing any Product, which in
no event will be less than five years.

13.5.4.    Affiliates, Sublicensees and Distributors. Each Party will (i) ensure that all applicable Affiliates of such
Party are covered under such Party’s insurance policies as described in Section 13.5.1 and (ii) require all of
its Sublicensees and Distributors to comply with the provisions and obligations under this Section 13.5 as if
such entity were such Party.

13.5.5.    No Limitation. The minimum amounts of insurance coverage required under this Section 13.5 will not be
construed  to  create  a  limit  of  liability  with  respect  to  a  Party’s  indemnification  obligations  under
Section  13.1  or  13.2,  as  applicable,  or  with  respect  to  such  Party’s  share  of  any  Liabilities  under  Section
13.4.

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

13.5.6.    Self-Insurance. Notwithstanding the foregoing, [***] may self-insure to the extent that it self-insures for

its other activities.

13.6.    Limitation of Consequential Damages. Except for (a) claims of a Third Party that are subject to indemnification
under this ARTICLE 13, (b) claims arising out of a Party’s willful misconduct, or (c) a Party’s breach of ARTICLE
15,  neither  Party  nor  any  of  its  Affiliates  will  be  liable  to  the  other  Party  or  its  Affiliates  for  any  incidental,
consequential, special, punitive or other indirect damages or lost or imputed profits or royalties, lost data or cost of
procurement of substitute goods or services, whether liability is asserted in contract, tort (including negligence and
strict product liability), indemnity or contribution, and irrespective of whether that Party or any representative of that
Party has been advised of, or otherwise might have anticipated the possibility of, any such loss or damage.

ARTICLE 14

TERM; TERMINATION

14.1.        Co-Co  Agreement  Term;  Expiration.  This  Agreement  is  effective  as  of  the  Effective  Date  and,  unless  earlier
terminated pursuant to the other provisions of this ARTICLE 14, will continue in full force and effect until there is
no  longer  any  Global  Development  Plan  or  Global  Commercialization  Plan  contemplating  Development  or
Commercialization of the Shared Products in the Territory.

14.2.    Termination of the Agreement.

14.2.1.        Vertex’s  Termination  for  Convenience.  Vertex  will  be  entitled  to  terminate  this  Agreement  for
convenience,  in  its  entirety  or  with  respect  to  one  or  more  Shared  Product(s),  by  providing  CRISPR
90  days’  written  notice  of  such  termination;  provided,  however,  that  if  any  termination  under  this
Section 14.2.1 with respect to a Shared Product occurs after such Shared Product has received Marketing
Approval, Vertex will provide CRISPR no less than 270 days’ written notice of such termination.

14.2.2.    Termination for Material Breach.

(a)    Vertex’s Right to Terminate. If CRISPR (or any CRISPR Entity(ies)) is in material breach of this
Agreement,  then  Vertex  may  deliver  notice  of  such  material  breach  to  CRISPR.  If  the  breach  is
curable, CRISPR will have [***] days from the receipt of such notice to cure such breach (except to
the  extent  such  breach  involves  the  failure  to  make  a  payment  when  due,  which  breach  must  be
cured within [***] Business Days following receipt of such notice). If either CRISPR fails to cure
such breach within such [***]-day or [***]-Business Day period, as

53

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

applicable, or the breach is not subject to cure, Vertex in its sole discretion may either (i) terminate
this Agreement (A) if such breach relates solely to a particular Shared Product, with respect to the
Shared Product affected by such breach or (B) if such breach relates to this Agreement as a whole, in
its  entirety,  by  providing  written  notice  to  CRISPR  or  (ii)  elect  to  exercise  the  alternative  remedy
provisions set forth in Section 14.5 (in lieu of termination).

(b)    CRISPR’s Right to Terminate. If Vertex is in material breach of this Agreement, then CRISPR may
deliver notice of such material breach to Vertex. If the breach is curable, Vertex will have [***] days
following receipt of such notice to cure such breach (except to the extent such breach involves the
failure  to  make  a  payment  when  due,  which  breach  must  be  cured  within  [***]  Business  Days
following receipt of such notice). If Vertex fails to cure such breach within the [***]-day or [***]-
Business  Day  period,  as  applicable,  or  the  breach  is  not  subject  to  cure,  CRISPR  in  its  sole
discretion may either  (i)  terminate  this Agreement  (A)  if  such  breach  relates  solely to a particular
Shared  Product,  with  respect  to  the  Shared  Product  affected  by  such  breach  or  (B)  if  such  breach
relates to this Agreement as a whole, in its entirety, by providing written notice to Vertex or (ii) elect
to exercise the alternative remedy provisions set forth in Section 14.5 (in lieu of termination).

(c)    Disputes Regarding Material Breach. Notwithstanding the foregoing, if the Breaching Party in this
Section 14.2.2 disputes in good faith the existence, materiality, or failure to cure of any such breach
that is not a payment breach, and provides notice to the Non-Breaching Party of such dispute within
the  relevant  cure  period,  the  Non-Breaching  Party  will  not  have  the  right  to  terminate  this
Agreement  in  accordance  with  this  Section  14.2.2,  unless  and  until  the  relevant  dispute  has  been
resolved. It is understood and acknowledged that during the pendency of such dispute, all the terms
and conditions of this Agreement will remain in effect and the Parties will continue to perform all of
their respective obligations hereunder.

14.2.3.    Termination for Patent Challenge. If a Party (the “Challenging Party”) (A) commences or actively and
voluntarily  participates  in  any  action  or  proceeding  (including  any  Patent  opposition  or  re-examination
proceeding),  or  otherwise  asserts  any  claim,  challenging  or  denying  the  validity  or  enforceability  of  any
claim  of  any  Patent  that  is  licensed  to  the  Challenging  Party  under  this  Agreement  or  (B)  actively  and
voluntarily

54

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

assists  any  other  Person  in  bringing  or  prosecuting  any  action  or  proceeding  (including  any  Patent
opposition or re-examination proceeding) challenging or denying the validity or enforceability of any claim
of any Patent that is licensed to the Challenging Party under this Agreement by the other Party (the “Non-
Challenging  Party”)  (each  of  (A)  and  (B),  a  “Patent  Challenge”),  then,  to  the  extent  permitted  by
Applicable Law, the Non-Challenging Party shall have the right, in its sole discretion, to give notice to the
Challenging Party that the Non-Challenging Party may terminate the license(s) granted under such Patent to
the  Challenging  Party    [***]  days  following  such  notice,  and,  unless  the  Challenging  Party  withdraws  or
causes  to  be  withdrawn  all  such  challenge(s),  or  in  the  case  of  ex-parte  proceedings,  multi-party
proceedings, or other Patent Challenges that the Challenging Party does not have the power to unilaterally
withdraw or cause to be withdrawn, the Challenging Party ceases assisting any other party to such Patent
Challenge and, to the extent the Challenging Party is a party to such Patent Challenge, it withdraws from
such Patent Challenge within such [***]-day period, the Non-Challenging Party shall have the right to deem
the  Challenging  Party  to  have  exercised  an  Opt-Out  with  respect  to  any  Shared  Product(s)  Covered  by  a
Patent that is the subject of such Patent Challenge, by providing written notice thereof to the Challenging
Party,  in  which  case  the  provisions  of  Section  14.3  shall  apply;  provided,  however,  [***].  The  foregoing
right of the Non-Challenging Party shall not apply with respect to any Patent Challenge where the Patent
Challenge  is  made  in  defense  of  an  assertion  of  the  relevant  Patent  that  is  first  brought  by  the  Non-
Challenging  Party  against  the  Challenging  Party.  For  the  avoidance  of  doubt,  any  participation  by  the
Challenging Party or its employees in any claim, challenge or proceeding in response to a subpoena or as
required under a pre-existing agreement between the Challenging Party’s employee(s) or consultant(s) and
their prior employer(s) shall not constitute active and voluntary participation or assistance and shall not give
rise  to  the  Non-Challenging  Party’s  right  to  deem  the  Challenging  Party  as  having  exercised  an  Opt-Out
with respect to any Shared Product hereunder.

14.2.4.    Termination for Insolvency.  If  CRISPR  (or  any  CRISPR  Entity(ies))  undergoes  any  Insolvency  Event,
then  Vertex  may  terminate  this  Agreement  in  its  entirety  effective  immediately  upon  written  notice  to
CRISPR. If an Insolvency Event occurs with respect to CRISPR (or any CRISPR Entity(ies)):

(a)        All  rights  and  licenses  now  or  hereafter  granted  by  CRISPR  to  Vertex  under  or  pursuant  to  this
Agreement, including, for the avoidance of doubt, any Exclusive Licenses, are, for all purposes of
Section 365(n) of the U.S. Bankruptcy Code, licenses of rights

55

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

to  “intellectual  property”  as  defined  in  the  U.S.  Bankruptcy  Code.  Upon  the  occurrence  of  any
Insolvency Event with respect to CRISPR (or any CRISPR Entity(ies)), CRISPR agrees that Vertex,
as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights
and elections under the U.S. Bankruptcy Code. CRISPR will, during the Co-Co Agreement Term,
create  and  maintain  current  copies  or,  if  not  amenable  to  copying,  detailed  descriptions  or  other
appropriate  embodiments,  to  the  extent  feasible,  of  all  intellectual  property  licensed  under  this
Agreement. Each Party acknowledges and agrees that “embodiments” of intellectual property within
the  meaning  of  Section  365(n)  include  laboratory  notebooks,  cell  lines,  product  samples  and
inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory
Approval)  and  rights  of  reference  therein,  the  Licensed  CRISPR  Technology  and  all  information
related  to  the  Licensed  CRISPR  Technology.  If  (x)  a  case  under  the  U.S.  Bankruptcy  Code  is
commenced by or against CRISPR (or any CRISPR Entity(ies)), (y) this Agreement is rejected as
provided  in  the  U.S.  Bankruptcy  Code,  and  (z)  Vertex  elects  to  retain  its  rights  hereunder  as
provided  in  Section  365(n)  of  the  U.S.  Bankruptcy  Code,  CRISPR  (in  any  capacity,  including
debtor-in-possession) and its successors and assigns (including a trustee) will:

(i)        provide  to  Vertex  all  such  intellectual  property  (including  all  embodiments  thereof)  held  by
CRISPR and such successors and assigns, or otherwise available to them, immediately upon
Vertex’s written request. Whenever CRISPR or any of its successors or assigns provides to
Vertex  any  of  the  intellectual  property  licensed  hereunder  (or  any  embodiment  thereof)
pursuant  to  this  Section  14.2.4(a)(i),  Vertex  will  have  the  right  to  perform  CRISPR’s
obligations  hereunder  with  respect  to  such  intellectual  property,  but  neither  such  provision
nor such performance by Vertex will release CRISPR from liability resulting from rejection
of the license or the failure to perform such obligations; and

(ii)    not interfere with Vertex’s rights under this Agreement, or any agreement supplemental hereto,
to  such  intellectual  property  (including  such  embodiments),  including  any  right  to  obtain
such intellectual property (or such embodiments) from another entity, to the extent provided
in Section 365(n) of the U.S. Bankruptcy Code.

56

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

(b)    All rights, powers and remedies of Vertex provided herein are in addition to and not in substitution for
any and all other rights, powers and remedies now or hereafter existing at law or in equity (including
the U.S. Bankruptcy Code) in the event of the commencement of a case under the U.S. Bankruptcy
Code with respect to CRISPR. The Parties agree that they intend the following rights to extend to
the  maximum  extent  permitted  by  Applicable  Law,  and  to  be  enforceable  under  U.S.  Bankruptcy
Code Section 365(n):

(i)        the  right  of  access  to  any  intellectual  property  rights  (including  all  embodiments  thereof)  of
CRISPR,  or  any  Third  Party  with  whom  CRISPR  contracts  to  perform  an  obligation  of
CRISPR under this Agreement, and, in the case of any such Third Party, which is necessary
for the Manufacture, use, sale, import or export of Shared Products; and

(ii)    the right to contract directly with any Third Party to complete the contracted work.

14.3.    Opt-Out.

14.3.1.    On a Shared Product-by-Shared Product basis, after [***], either Party may opt out of this Agreement with
respect to such Shared Product (the “Opt-Out Product”) upon [***] days’ notice to the other Party (“Opt-
Out”).  The  other  Party  shall  pay  such  opting  out  Party  royalties  on  Net  Sales  (as  defined  in  the
Collaboration Agreement) of such Opt-Out Product (“Opt-Out Royalties”) in accordance with this Section
14.3, and the terms of Sections 7.5.2, 7.5.3, 7.5.4 and 7.5.5 of the Collaboration Agreement shall apply to
such royalties, mutatis mutandis.  The  applicable  royalty  rates  shall  be  determined  in  accordance  with  the
table set forth below based on the timing of the Opt-Out notice for the applicable Opt-Out Product. Upon
the other Party’s receipt of such notice, all rights and obligations under this Agreement with respect to the
Opt-Out Product shall terminate, except for the obligations set forth in this Section 14.3.

14.3.2.        If  the  opting  out  Party  is  CRISPR,  the  Opt-Out  Product  shall  be  deemed  a  Product  (as  defined  in  the
Collaboration  Agreement)  directed  to  a  Collaboration  Target  other  than  a  [***]  under  the  Collaboration
Agreement,  and  the  terms  and  conditions  of  the  Collaboration  Agreement  shall  apply  with  respect  to  the
Opt-Out Product, provided that, in lieu of the royalty rates payable under Section 7.5.1 of the Collaboration
Agreement Vertex shall pay royalties at the rates set forth in this Section 14.3; and provided, further,  that
Vertex  shall  have  no  obligation  to  pay  to  CRISPR  any  milestone  payment  under  Section  7.3  of  the
Collaboration Agreement with respect to such Opt-Out Product.

14.3.3.    If the opting out Party is Vertex, the Parties shall negotiate in good faith a termination agreement for the
Opt-Out Product, including the obligation to pay royalties as set forth in this Section 14.3 and the following
provisions:

(a)        CRISPR  (acting  directly  or  through  one  or  more  Affiliates  or  Sublicensees)  will  use  Commercially

Reasonable Efforts to [***] for the [***] in all [***]

(which  detail  shall  be  at  least  sufficient  for  Vertex  to  evaluate  CRISPR’s  compliance  with  its
obligations under this Agreement) CRISPR’s plans for (a) the Development of the Opt-Out Product
through [***] and (b) starting upon [***] for the Opt-Out Product and continuing thereafter until the
expiration  of  the  applicable  Royalty  Term,  Commercialization  of  the  Opt-Out  Product,  as
appropriate for the

(d)    following the first sale of the Opt-Out Product giving rise to Net Sales (as defined in the Collaboration
Agreement), within [***] days after the end of each Calendar Quarter, CRISPR will deliver a report
to  Vertex  specifying  on  a  country-by-country  basis:  [***].  All  royalty  payments  due  for  each
Calendar  Quarter  will  be  due  and  payable  within  [***]  days  after  CRISPR’s  delivery  of  the
applicable report.

14.3.4.    Following any Opt-Out with respect to an Opt-Out Product, the opting out Party shall, within a reasonable
time as mutually agreed by the Parties, (i) transfer to the other Party all Regulatory Filings with respect to
such  Opt-Out  Product,  (ii)  conduct  any  technology  transfer  with  respect  to  such  Opt-Out  Product  as
reasonably  requested  by  the  non-opting  out  Party  and  (iii)  use  reasonable  efforts  to  transfer  to  the  non-
opting out Party any existing relationships with key vendors to the extent relating to such Opt-Out Product.
The Expenses of all activities under this Section 14.3.4 shall be shared equally by the Parties.

14.3.5.    If the opting out Party is conducting Manufacturing activities with respect to the Opt-Out Product at the
time of such Opt-Out, the opting out Party will continue to supply the other Party’s requirements of the Opt-
Out Product, at the other Party’s expense at cost of Manufacturing such Opt-Out Product, until such time as
the  Parties  are  able  to  complete  a  technology  transfer  of  the  applicable  Manufacturing  technology  to  the
other  Party  or  its  designated  CMO,  and  the  other  Party  or  such  CMO  is  capable  of  supplying  the  other
Party’s  requirements  of  the  Opt-Out  Product.  The  Expenses  of  technology  transfer  activities  under  this
Section 14.3.5, including any Expenses incurred in establishing a CMO capable of Manufacturing the Opt-
Out Products, shall be shared equally by the Parties.

14.3.6.    For the avoidance of doubt, the allocation of [***] and [***] pursuant to Section [***] with respect to an
Opt-Out Product shall terminate upon the effectiveness of the Opt-Out for such Opt-Out Product.

14.4.        Consequences  of  Expiration  or  Certain  Terminations  of  the  Agreement.  If  this  Agreement  expires  or  is
terminated by a Party with respect to one or more Shared Products (each, a “Terminated Product”) in accordance
with  Section  14.2  at  any  time  and  for  any  reason,  the  following  terms  will  apply  with  respect  to  each  Terminated
Product:

14.4.1.    The Parties will return (or destroy, as directed by the other Party) all data, files, records and other materials

containing or comprising the other

59

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would
cause competitive harm if publicly disclosed.

Party’s  Confidential  Information  with  respect  to  the  Terminated  Product,  unless  such  Confidential
Information also relates to other products that are subject to the Collaboration Agreement or are necessary
for  a  Party  to  exercise  its  rights  under  Section  14.3.  Notwithstanding  the  foregoing,  the  Parties  will  be
permitted  to  retain  one  copy  of  such  data,  files,  records,  and  other  materials  for  archival  and  legal
compliance purposes.

14.4.2.        Termination  or  expiration  of  this  Agreement  for  any  reason  will  be  without  prejudice  to  any  rights  or
financial  compensation  that  will  have  accrued  to  the  benefit  of  a  Party  with  respect  to  the  Terminated
Product prior to such termination or expiration. Such termination or expiration will not relieve a Party from
obligations that are expressly indicated to survive the termination or expiration of this Agreement.

14.4.3.    Except as may be necessary for a Party to exercise the rights set forth in Section 14.3, all licenses granted
by a Party to the other Party under this Agreement with respect to the Terminated Product will terminate
and each Party and its Affiliates will cease all Research, Development, Manufacture and Commercialization
activities with respect to the Terminated Product.

14.4.4.    Except as may be necessary for a Party to exercise the rights set forth in Section 14.3, Vertex will assign
back to the CRISPR Entity designated by CRISPR AG any Patents assigned to Vertex under Section 8.1.3
of the Collaboration Agreement that relate to the Terminated Product to the extent that such Patents do not
also  relate  to  other  products  for  which  Vertex  is  retaining  an  exclusive  license  under  the  Collaboration
Agreement.

14.4.5.    Except as set forth in Section 14.3, neither Party will have any further rights or obligations with respect to

16.4.    Representation  by  Legal  Counsel. Each  Party  hereto  represents  that  it  has  been  represented  by  legal  counsel  in
connection with this Agreement and acknowledges that it has participated in the drafting hereof. In interpreting and

or  to  such  other  address  as  the  Party  to  whom  notice  is  to  be  given  may  have  furnished  to  the  other  Party  in  writing  in
accordance herewith. Any such notice will be deemed to have been given: (a) when delivered if personally delivered on a
Business  Day  (or  if  delivered  or  sent  on  a  non-business  day,  then  on  the  next  Business  Day);  (b)  on  receipt  if  sent  by

delivered hereunder to each of CRISPR UK, CRISPR AG, CRISPR Inc. and Tracr.

16.6.        Amendment.  No  amendment,  modification  or  supplement  of  any  provision  of  this  Agreement  will  be  valid  or
effective unless made in writing and signed by a duly authorized officer of each of Vertex Parent, Vertex UK and
CRISPR AG, CRISPR Inc., CRISPR UK and Tracr.

16.7.    Waiver. No provision of this Agreement will be waived by any act, omission or knowledge of a Party or its agents or

provision  itself.  Written  waiver  of  any  provision  of  this  Agreement  by  of  any  one  of  the  CRISPR  Entities  in
accordance with this Section 16.7 shall be binding upon each of CRISPR UK, CRISPR AG, CRISPR Inc. and Tracr.

unenforceable, the same will not affect any other portion of this Agreement, as it is the intent of the Parties that this
Agreement will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest
extent possible. In any such event, this Agreement will be construed as if such clause of portion thereof had never
been contained in this Agreement, and there will be deemed substituted therefor such provision as will most nearly
carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law.

63

[***] = Certain confidential information contained in this document, marked by brackets, has been omitted because it is both (i) not material and (ii) would

acquired from the other Party under this Agreement or any products using such technical information to a location or

obtaining the written consent to do so from the appropriate Governmental Authority.

16.11.    Governing Law. This Agreement, and all claims arising under or in connection therewith, will be governed by and

conflict of law principles thereof.

16.12.        Entire  Agreement.  This  Agreement,  together  with  the  Collaboration  Agreement,  constitutes  and  contains  the

respecting the subject matter hereof and thereof.

16.13.        Independent  Contractors.  Both  Parties  are  independent  contractors  under  this  Agreement.  Nothing  herein
contained  will  be  deemed  to  create  an  employment,  agency,  joint  venture  or  partnership  relationship  between  the
Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon
one Party for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter
into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to
bind the other Party in any respect whatsoever.

Schedule A

[***] ARBITRATION

Selection of [***] Expert and Submission of Positions. The Parties will select and agree upon a mutually acceptable independent
Third Party expert who is neutral, disinterested and impartial, and has the experience specified in Section 2.8 for the applicable
dispute (the “[***] Expert”). If the Parties are unable to mutually agree upon a [***] Expert within [***] days following the
delivery of the request for [***] Arbitration, then upon request by either Party, the [***] Expert will be an arbitrator appointed by
Judicial and Mediation Services (“JAMS”), which arbitrator need not have the above-described experience. Once the [***] Expert
has been selected, each Party will within [***] days following selection of the [***] Expert provide the [***] Expert and the other
Party with a written report setting forth its position with respect to the substance of the dispute and may submit a revised or updated
report and position to the [***] Expert within [***] days of receiving the other Party’s report. If so requested by the [***] Expert,
each Party will make oral submissions to the [***] Expert based on such Party’s written report, and each Party will have the right to
be present during any such oral submissions.

JAMS Supervision. In the event the [***] Expert is a JAMS arbitrator selected by JAMS as provided in this Schedule A, the matter
will be conducted as a binding arbitration in accordance with JAMS procedures, as modified by this Schedule A (including that the
arbitrator will adopt as his or her decision the position of one Party or the other, as described below). In such event, the arbitrator
may retain a Third Party expert with the same experience specified in Section 2.8 for the [***] Expert to assist in rendering such
decision, and the expenses of any such expert will be shared by the Parties as costs of the arbitration as provided in this Schedule A.

Determination by the [***] Expert. The [***] Expert will, no later than [***] days after the last submission of the written reports
and, if any, oral submissions, select one of the Party’s positions as his or her final decision, and will not have the authority to modify
either Party’s position or render any substantive decision other than to so select the position of either Party as set forth in their
respective written report (as initially submitted, or as revised in accordance with this Schedule A, as applicable). The decision of the
[***] Expert will be the sole, exclusive and binding remedy between them regarding the dispute submitted to such [***] Expert.

Location; Costs. Unless otherwise mutually agreed upon by the Parties in writing, the in-person portion (if any) of such
proceedings will be conducted in Boston, Massachusetts. [***]

Timetable for Completion in [***] Days. The Parties will use, and will direct the [***] Expert to use, commercially reasonable
efforts to resolve a dispute within [***] days after the selection of the [***] Expert, or if resolution within [***] days is not
reasonably achievable, as determined by the [***] Expert, then as soon thereafter as is reasonably practicable

Revaluation  Date  to  be  used  for  calculating  Dollar  Equivalent  amounts  of  Credit  Extensions  and  Outstanding  Amounts
denominated in Alternative Currencies. Such Spot Rates shall become effective as of such Revaluation Date and shall be the
Spot Rates employed in converting any amounts between the applicable currencies until the next Revaluation Date to occur.
Except  for  purposes  of  financial  statements  delivered  by  Loan  Parties  hereunder  or  calculating  financial  covenants
hereunder or except as otherwise provided herein, the applicable amount of any currency (other than Dollars) for purposes
of  the  Loan  Documents  shall  be  such  Dollar  Equivalent  amount  as  so  determined  by  the  Administrative  Agent  or  the
applicable L/C Issuer, as applicable.

(b)        Wherever  in  this  Agreement  in  connection  with  a  Borrowing,  conversion,  continuation  or  prepayment  of  a
Eurocurrency  Rate  Loan  or  the  issuance,  amendment  or  extension  of  a  Letter  of  Credit,  an  amount,  such  as  a  required
minimum or multiple amount, is expressed in Dollars, but such Borrowing, Eurocurrency Rate Loan or Letter of Credit is
denominated in an Alternative Currency, such amount shall be the relevant Alternative Currency Equivalent of such Dollar
amount (rounded to the nearest unit of such Alternative Currency, with 0.5 of a unit being rounded upward), as determined
by the Administrative Agent or the applicable L/C Issuer, as the case may be.

(c)    The Administrative Agent does not warrant, nor accept responsibility, nor shall the Administrative Agent have
any  liability  with  respect  to  the  administration,  submission  or  any  other  matter  related  to  the  rates  in  the  definition  of
“Eurocurrency Rate” or with respect to any rate that is an alternative or replacement for or successor to any of such rates
(including, without limitation, any LIBOR Successor Rate) or the effect of any of the foregoing, or of any LIBOR Successor
Rate Conforming Changes.

(d)        Any  amount  specified  in  this  Agreement  (other  than  in  Articles  II,  IX  and  X)  or  any  of  the  other  Loan
Documents  to  be  in  Dollars  shall  also  include  the  equivalent  of  such  amount  in  any  currency  other  than  Dollars,  such
equivalent amount thereof in the applicable currency to be determined by the Administrative Agent at such time on the basis
of the Spot Rate (as defined below) for the purchase of such currency with Dollars. For purposes of this Section 1.08, the
“Spot Rate” for a currency means the rate determined by the Administrative Agent to be the rate quoted by the Person acting
in such capacity as the spot rate for the purchase by such Person of such currency with another currency through its principal
foreign  exchange  trading  office  at  approximately  11:00  a.m.  on  the  date  two  (2)  Business  Days  prior  to  the  date  of  such
determination;  provided  that  the  Administrative  Agent  may  obtain  such  Spot  Rate  from  another  financial  institution
designated by the Administrative Agent if the Person acting in such capacity does not have as of the date of determination a
spot buying rate for any such currency.

1.09    Additional Alternative Currencies.

(a)    The Company may from time to time request that Eurocurrency Rate Loans be made and/or Letters of Credit be
issued in a currency other than those specifically listed in the definition of “Alternative Currency”; provided that (i) such
requested  currency  is  an  Eligible  Currency  and  (ii)  such  requested  currency  shall  only  be  treated  as  a  “LIBOR  Quoted
Currency” to the extent that there is published LIBOR rate for such currency. In the case of any such request with respect to
the making of Eurocurrency Rate Loans, such request shall be subject to the approval of the Administrative Agent and each
Lender with a Revolving Commitment under which such currency is requested to be made available; and in the case of any
such  request  with  respect  to  the  issuance  of  Letters  of  Credit,  such  request  shall  be  subject  to  the  approval  of  the
Administrative Agent and the applicable L/C Issuer.

(b)    Any such request shall be made to the Administrative Agent not later than 11:00 a.m., twenty (20) Business
Days prior to the date of the desired Credit Extension (or such other time or date as may be agreed by the Administrative
Agent and, in the case of any such request pertaining to Letters of Credit, the L/C Issuers, in its or their sole discretion). In
the case of any such request pertaining to Eurocurrency Rate Loans, the Administrative Agent shall promptly notify each
Appropriate Lender thereof; and in the case of any such request pertaining to Letters of Credit, the Administrative Agent
shall  promptly  notify  the  L/C  Issuers  thereof.  Each  Appropriate  Lender  (in  the  case  of  any  such  request  pertaining  to
Eurocurrency  Rate  Loans)  or  the  L/C  Issuers  (in  the  case  of  a  request  pertaining  to  Letters  of  Credit)  shall  notify  the
Administrative Agent, not later than 11:00 a.m., ten (10) Business Days after receipt of such request whether it consents, in
its sole discretion, to the making of Eurocurrency Rate Loans or the issuance of Letters of Credit, as the case may be, in such
requested currency.

(c)    Any failure by a Lender or any L/C Issuer, as the case may be, to respond to such request within the time period
specified in the preceding sentence shall be deemed to be a refusal by such Lender or such L/C Issuer, as the case may be, to
permit  Eurocurrency  Rate  Loans  to  be  made  or  Letters  of  Credit  to  be  issued  in  such  requested  currency.  If  the
Administrative  Agent  and  all  the  Appropriate  Lenders  consent  to  making  Eurocurrency  Rate  Loans  in  such  requested
currency and the Administrative Agent and such Lenders reasonably determine that an appropriate interest rate is available
to  be  used  for  such  requested  currency,  the  Administrative  Agent  shall  so  notify  the  Company  and  (i)  the  Administrative
Agent and such Lenders may amend the definition of Eurocurrency Rate for any Non-LIBOR Quoted Currency to the extent
necessary to add the applicable Eurocurrency Rate for such currency and (ii) to the extent the definition of Eurocurrency
Rate  reflects  the  appropriate  interest  rate  for  such  currency  or  has  been  amended  to  reflect  the  appropriate  rate  for  such
currency,  such  currency  shall  thereupon  be  deemed  for  all  purposes  to  be  an  Alternative  Currency  for  purposes  of  any
Borrowings of Eurocurrency Rate Loans. If the Administrative Agent and the L/C Issuers consent to the issuance of Letters
of  Credit  in  such  requested  currency,  the  Administrative  Agent  shall  so  notify  the  Company  and  (iii)  the  Administrative
Agent and the L/C Issuers may amend the

definition  of  Eurocurrency  Rate  for  any  Non-LIBOR  Quoted  Currency  to  the  extent  necessary  to  add  the  applicable
Eurocurrency  Rate  for  such  currency  and  (iv)  to  the  extent  the  definition  of  Eurocurrency  Rate  reflects  the  appropriate
interest  rate  for  such  currency  or  has  been  amended  to  reflect  the  appropriate  rate  for  such  currency,  such  currency  shall
thereupon be deemed for all purposes to be an Alternative Currency, for purposes of any Letter of Credit issuances. If the
Administrative  Agent  shall  fail  to  obtain  consent  to  any  request  for  an  additional  currency  under  this  Section  1.09,  the
Administrative Agent shall promptly so notify the Company. Any specified currency of an Existing Letter of Credit that is
neither Dollars nor one of the Alternative Currencies specifically listed in the definition of “Alternative Currency” shall be
deemed an Alternative Currency with respect to such Existing Letter of Credit only.

1.10    Change of Currency.

(a)    Each obligation of the Borrowers to make a payment denominated in the national currency unit of any member
state  of  the  European  Union  that  adopts  the  Euro  as  its  lawful  currency  after  the  date  hereof  shall  be  redenominated  into
Euro at the time of such adoption. If, in relation to the currency of any such member state, the basis of accrual of interest
expressed in this Agreement in respect of that currency shall be inconsistent with any convention or practice in the London
interbank market for the basis of accrual of interest in respect of the Euro, such expressed basis shall be replaced by such
convention  or  practice  with  effect  from  the  date  on  which  such  member  state  adopts  the  Euro  as  its  lawful  currency;
provided that, if any Borrowing in the currency of such member state is outstanding immediately prior to such date, such
replacement shall take effect, with respect to such Borrowing, at the end of the then current Interest Period.

(b)        Each  provision  of  this  Agreement  shall  be  subject  to  such  reasonable  changes  of  construction  as  the
Administrative Agent may from time to time specify to be appropriate to reflect the adoption of the Euro by any member
state of the European Union and any relevant market conventions or practices relating to the Euro.

(c)        Each  provision  of  this  Agreement  also  shall  be  subject  to  such  reasonable  changes  of  construction  as  the
Administrative Agent may from time to time specify to be appropriate to reflect a change in currency of any other country
and any relevant market conventions or practices relating to the change in currency.

ARTICLE II

COMMITMENTS AND CREDIT EXTENSIONS

2.01    Revolving Loans. Subject  to  the  terms  and  conditions  set  forth  herein,  each  Revolving  Lender  severally  agrees  to  make
loans (each such loan, a “Revolving Loan”) to the Borrowers, in Dollars or in one or more Alternative Currencies, from time
to time, on any Business Day during the Availability Period, in an aggregate amount not to exceed at any time outstanding
the  amount  of  such  Lender’s  Revolving  Commitment;  provided,  however,  that  after  giving  effect  to  any  Revolving
Borrowing, (a) the Total Revolving

Outstandings shall not exceed the Aggregate Revolving Commitments, (b) the Revolving Exposure of any Lender shall not
exceed  such  Revolving  Lender’s  Revolving  Commitment,  (c)  the  Revolving  Exposure  of  any  Lender  under  any  Class  of
Revolving  Commitments  shall  not  exceed  such  Lender’s  Revolving  Commitment  of  such  Class,  and  (d)  the  aggregate
Outstanding  Amount  of  all  Loans  denominated  in  Alternative  Currencies  shall  not  exceed  the  Alternative  Currency
Sublimit.  Within  the  limits  of  each  Revolving  Lender’s  Revolving  Commitment,  and  subject  to  the  other  terms  and
conditions  hereof,  the  Borrowers  may  borrow  Revolving  Loans,  prepay  under  Section  2.05,  and  reborrow  under  this
Section 2.01. Revolving Loans may be Base Rate Loans or Eurocurrency Rate Loans, as further provided herein; provided,
however,  any  Revolving  Borrowings  made  on  the  Closing  Date  or  any  of  the  three  (3)  Business  Days  (or  such  longer
applicable  period,  in  accordance  with  Section  2.02(a),  for  Revolving  Borrowings  denominated  in  Alternative  Currencies
other than Euro or Sterling) following the Closing Date shall be made as Base Rate Loans unless the Company delivers a
Funding  Indemnity  Letter  not  less  than  three  (3)  Business  Days  (or  such  longer  applicable  period,  in  accordance  with
Section 2.02(a), for Revolving Borrowings denominated in Alternative Currencies other than Euro or Sterling) prior to the
date of such Revolving Borrowing.

2.02    Borrowings, Conversions and Continuations of Loans.

(a)        Notice  of  Borrowing.  Each  Borrowing,  each  conversion  of  Loans  from  one  Type  to  the  other,  and  each
continuation  of  Eurocurrency  Rate  Loans  shall  be  made  upon  the  applicable  Borrower’s  irrevocable  notice  to  the
Administrative Agent, which may be given by: (i) telephone or (ii) a Loan Notice; provided that any telephonic notice must
be  confirmed  immediately  by  delivery  to  the  Administrative  Agent  of  a  Loan  Notice.  Each  such  Loan  Notice  must  be
received by the Administrative Agent not later than 11:00 a.m. (A) three (3) Business Days prior to the requested date of any
Borrowing of, conversion to or continuation of Eurocurrency Rate Loans denominated in Dollars, Euro or Sterling, or of any
conversion of Eurocurrency Rate Loans denominated in Dollars to Base Rate Loans, (B) four (4) Business Days (or five (5)
Business  Days  in  the  case  of  a  Special  Notice  Currency) prior  to  the  requested  date  of  any  Borrowing  or  continuation  of
Eurocurrency Rate Loans denominated in other Alternative Currencies, and (C) on the requested date of any Borrowing of
Base Rate Loans; provided, however, that if the applicable Borrower wishes to request Eurocurrency Rate Loans having an
Interest Period other than one (1), two (2), three (3) or six (6) months in duration as provided in the definition of “Interest
Period”, the applicable notice must be received by the Administrative Agent not later than 11:00 a.m. (x) four (4) Business
Days prior to the requested date of such Borrowing, conversion or continuation of Eurocurrency Rate Loans denominated in
Dollars, Euro or Sterling, or (y) five (5) Business Days (or six (6) Business Days in the case of a Special Notice Currency)
prior to the requested date of such Borrowing, conversion or continuation of Eurocurrency Rate Loans denominated in other
Alternative Currencies, whereupon the Administrative Agent shall give prompt notice to the Appropriate Lenders of such
request and determine whether the requested Interest Period is acceptable to all of them. Not later than 11:00 a.m., (1) three
(3)

 
Business  Days  before  the  requested  date  of  such  Borrowing,  conversion  or  continuation  of  Eurocurrency  Rate  Loans
denominated in Dollars, Euro or Sterling, or (2) four (4) Business Days (or five (5) Business Days in the case of a Special
Notice  Currency)  prior  to  the  requested  date  of  such  Borrowing,  conversion  or  continuation  of  Eurocurrency  Rate  Loans
denominated in other Alternative Currencies, the Administrative Agent shall notify the applicable Borrower (which notice
may be by telephone) whether or not the requested Interest Period has been consented to by all the Lenders. Each Borrowing
of,  conversion  to  or  continuation  of  Eurocurrency  Rate  Loans  shall  be  in  a  principal  amount  of  $5,000,000  or  a  whole
multiple  of  $1,000,000  in  excess  thereof.  Except  as  provided  in  Sections  2.03(c)  and  2.04(c),  each  Borrowing  of  or
conversion to Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.
Each Loan Notice and each telephonic notice shall specify (I) whether the applicable Borrower is requesting a Borrowing, a
conversion of Loans from one Type to the other, or a continuation of Loans, as the case may be, (II) the requested date of the
Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (III) the principal amount of
Loans to be borrowed, converted or continued, (IV) the Type of Loans to be borrowed or to which existing Loans are to be
converted, (V) if applicable, the duration of the Interest Period with respect thereto, (VI) the currency of the Loans to be
borrowed and (VII) the relevant Borrower requesting such Borrowing. If the applicable Borrower fails to specify a currency
in a Loan Notice requesting a Borrowing, then the Loans so requested shall be made in Dollars. If the applicable Borrower
fails  to  specify  a  Type  of  Loan  in  a  Loan  Notice  or  if  the  applicable  Borrower  fails  to  give  a  timely  notice  requesting  a
conversion  or  continuation,  then  the  applicable  Loans  shall  be  made  as,  or  converted  to,  Base  Rate  Loans;  provided,
however, that in the case of a failure to timely request a continuation of Loans denominated in an Alternative Currency, such
Loans shall be continued as Eurocurrency Rate Loans in their original currency with an Interest Period of one (1) month.
Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect
with respect to the applicable Eurocurrency Rate Loans. If the applicable Borrower requests a Borrowing of, conversion to,
or  continuation  of  Eurocurrency  Rate  Loans  in  any  such  Loan  Notice,  but  fails  to  specify  an  Interest  Period,  it  will  be
deemed  to  have  specified  an  Interest  Period  of  one  (1)  month.  Notwithstanding  anything  to  the  contrary  herein,  each
Swingline  Loan  shall  be  made  as  a  Base  Rate  Loan  and  may  not  be  converted  to  a  Eurocurrency  Rate  Loan.  Except  as
provided  pursuant  to  Section  2.12(a),  no  Loan  may  be  converted  into  or  continued  as  a  Loan  denominated  in  a  different
currency, but instead must be repaid in the original currency of such Loan and reborrowed in the other currency.

(b)        Advances.  Following  receipt  of  a  Loan  Notice,  the  Administrative  Agent  shall  promptly  notify  each
Appropriate  Lender  of  the  amount  (and  currency)  of  its  Applicable  Percentage  of  the  applicable  Loans,  and  if  no  timely
notice of a conversion or continuation is provided by the applicable Borrower, the Administrative Agent shall notify each
Appropriate Lender of the details of any automatic conversion to Base Rate Loans or continuation of Loans denominated in
a currency other than Dollars, in each case as described in Section 2.02(a). In the case of a Borrowing, each Appropriate

Lender shall make the amount of its Loan available to the Administrative Agent in Same Day Funds at the Administrative
Agent’s Office for the applicable currency not later than 1:00 p.m., in the case of any Loan denominated in Dollars, and not
later than the Applicable Time specified by the Administrative Agent in the case of any Loan in an Alternative Currency, in
each case on the Business Day specified in the applicable Loan Notice. Upon satisfaction of the applicable conditions set
forth in Section 4.02 (and, if such Borrowing is the initial Credit Extension, Section 4.01, or, if applicable, Section 2.19), the
Administrative Agent shall make all funds so received available to the applicable Borrower in like funds as received by the
Administrative Agent either by (i) crediting the account of the applicable Borrower on the books of Bank of America with
the amount of such funds or (ii) wire transfer of such funds, in each case in accordance with instructions provided to (and
reasonably acceptable  to)  the  Administrative  Agent  by  the  applicable  Borrower; provided, however,  that  if,  on  the  date  a
Loan  Notice  with  respect  to  a  Revolving  Borrowing  is  given  by  the  applicable  Borrower,  there  are  L/C  Borrowings
outstanding, then the proceeds of such Revolving Borrowing, first, shall be applied to the payment in full of any such L/C
Borrowings, and second, shall be made available to the applicable Borrower as provided above; provided further, however,
that no Revolving Borrowing by a Designated Foreign Borrower shall be used to pay any L/C Borrowings of or attributable
to any U.S. Loan Party (or any other Domestic Subsidiary).

(c)    Eurocurrency Rate Loans. Except as otherwise provided herein, a Eurocurrency Rate Loan may be continued or
converted only on the last day of an Interest Period for such Eurocurrency Rate Loan. During the existence of an Event of
Default, no Loans may be requested as, converted to or continued as Eurocurrency Rate Loans without the consent of the
Required  Lenders,  and  the  Required  Lenders  may  demand  that  any  or  all  of  the  outstanding  Eurocurrency  Rate  Loans
denominated in Dollars be converted immediately to Base Rate Loans and any or all of the then outstanding Eurocurrency
Rate Loans denominated in an Alternative Currency be prepaid, or redenominated into Dollars in the amount of the Dollar
Equivalent thereof, on the last day of the then current Interest Period with respect thereto.

(d)    Interest Rates. Each determination of an interest rate by the Administrative Agent pursuant to any provision of

this Agreement shall be conclusive and binding on the Borrowers and the Lenders in the absence of manifest error.

(e)    Interest Periods. After giving effect to all Revolving Borrowings, all conversions of Revolving Loans from one
Type to the other, and all continuations of Revolving Loans as the same Type, there shall not be more than ten (10) Interest
Periods in effect in respect of the Revolving Facility.

(f)    Cashless Settlement Mechanism. Notwithstanding anything to the contrary in this Agreement, any Lender may
exchange,  continue  or  rollover  all  or  a  portion  of  its  Loans  in  connection  with  any  refinancing,  extension,  incremental
increase, loan modification or similar transaction permitted by the terms of this Agreement,

pursuant to a cashless settlement mechanism approved by the Company, the Administrative Agent and such Lender.

2.03    Letters of Credit.

(a)    The Letter of Credit Commitment.

(i)    Subject to the terms and conditions set forth herein, (A) each L/C Issuer agrees, in reliance upon the
agreements of the Revolving Lenders set forth in this Section 2.03, (1) from time to time on any Business Day during
the  period  from  the  Closing  Date  until  the  applicable  Letter  of  Credit  Expiration  Date,  to  issue  Letters  of  Credit
denominated  in  Dollars  or  in  one  or  more  Alternative  Currencies  for  the  account  of  any  Borrower  or  any  of  its
Restricted  Subsidiaries,  and  to  amend  or  extend  Letters  of  Credit  previously  issued  by  it,  in  accordance  with
Section 2.03(b) and (2) to honor drawings under the Letters of Credit; and (B) the Revolving Lenders severally agree
to  participate  in  Letters  of  Credit  issued  for  the  account  of  any  Borrower  or  its  Restricted  Subsidiaries  and  any
drawings  thereunder;  provided  that  after  giving  effect  to  any  L/C  Credit  Extension  with  respect  to  any  Letter  of
Credit,  (x)  the  Total  Revolving  Outstandings  shall  not  exceed  the  Aggregate  Revolving  Commitments,  (y)  the
Revolving Exposure  of  any  Revolving  Lender  shall  not  exceed  such  Lender’s Revolving Commitment and (z) the
Outstanding Amount of the L/C Obligations shall not exceed the Letter of Credit Sublimit; and provided further that
no Letter of Credit denominated in any Alternative Currency may be issued by any L/C Issuer other than Bank of
America,  through  itself  or  through  one  of  its  designated  Affiliates  or  branch  offices,  in  its  capacity  as  such.  Each
request by a Borrower for the issuance or amendment of a Letter of Credit shall be deemed to be a representation by
such Borrower that the L/C Credit Extension so requested complies with the conditions set forth in the proviso to the
preceding  sentence.  Within  the  foregoing  limits,  and  subject  to  the  terms  and  conditions  hereof,  the  Borrowers’
ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrowers may, during the foregoing
period,  obtain  Letters  of  Credit  to  replace  Letters  of  Credit  that  have  expired  or  that  have  been  drawn  upon  and
reimbursed in accordance with the terms hereof. All Existing Letters of Credit shall be deemed to have been issued
pursuant hereto and deemed L/C Obligations, and from and after the Closing Date shall be subject to and governed
by the terms and conditions hereof.

(ii)    No L/C Issuer shall issue any Letter of Credit if:

(A)        subject  to  Section  2.03(b)(iv),  the  expiry  date  of  the  requested  Letter  of  Credit  would  occur
more than twelve (12) months after the date of issuance or last extension, unless the Administrative Agent
and such L/C Issuer have approved such expiry date; or

(B)        the  expiry  date  of  such  requested  Letter  of  Credit  would  occur  after  the  Letter  of  Credit
Expiration  Date,  unless  the  Administrative  Agent  and  such  L/C  Issuer  have  approved  such  expiry  date  (it
being  understood  that  in  the  event  the  expiry  date  of  any  requested  Letter  of  Credit  would  occur  after  the
Letter  of  Credit  Expiration  Date,  from  and  after  the  Letter  of  Credit  Expiration  Date,  the  Borrowers  shall
immediately  Cash  Collateralize  the  then  Outstanding  Amount  of  all  L/C  Obligations  in  respect  of  such
Letters of Credit in accordance with Section 2.14);

(iii)    No L/C Issuer shall be under any obligation to issue any Letter of Credit if:

(A)    any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms
purport to enjoin or restrain such L/C Issuer from issuing the Letter of Credit, or any Law applicable to such
L/C  Issuer  or  any  request  or  directive  (whether  or  not  having  the  force  of  Law)  from  any  Governmental
Authority with jurisdiction over such L/C Issuer shall prohibit, or request that such L/C Issuer refrain from,
the issuance of letters of credit generally or the Letter of Credit in particular or shall impose upon such L/C
Issuer with respect to the Letter of Credit any restriction, reserve or capital requirement (for which such L/C
Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such
L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which
such L/C Issuer in good faith deems material to it;

(B)        the  issuance  of  the  Letter  of  Credit  would  violate  one  or  more  policies  of  such  L/C  Issuer

applicable to letters of credit generally;

(C)        except  as  otherwise  agreed  by  the  Administrative  Agent  and  such  L/C  Issuer,  the  Letter  of

Credit is in an initial stated amount less than $50,000;

(D)        except  as  otherwise  agreed  by  the  Administrative  Agent  and  such  L/C  Issuer,  the  Letter  of

Credit is to be denominated in a currency other than Dollars or an Alternative Currency;

(E)    any Revolving Lender is at that time a Defaulting Lender, unless such L/C Issuer has entered
into  arrangements,  including  the  delivery  of  Cash  Collateral,  satisfactory  to  such  L/C  Issuer  (in  its  sole
discretion) with the applicable Borrowers or such Revolving Lender to eliminate such L/C Issuer’s actual or
potential Fronting Exposure (after giving effect to Section 2.15(a)(iv)) with respect to the Defaulting Lender
arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other L/C
Obligations as to which such L/C Issuer

has actual or potential Fronting Exposure, as it may elect in its sole discretion;

(F)        the  Letter  of  Credit  contains  any  provisions  for  automatic  reinstatement  of  the  stated  amount

after any drawing thereunder;

(G)    such L/C Issuer does not as of the issuance date of the requested Letter of Credit issue Letters of

Credit in the requested currency; or

(H)    the requested Letter of Credit is to be issued for the benefit of an Irish beneficiary.

(iv)    No L/C Issuer shall amend any Letter of Credit if such L/C Issuer would not be permitted at such time

to issue the Letter of Credit in its amended form under the terms hereof.

(v)    No L/C Issuer shall be under any obligation to amend any Letter of Credit if (A) such L/C Issuer would
have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the
beneficiary of such Letter of Credit does not accept the proposed amendment to the Letter of Credit.

(vi)        Each  L/C  Issuer  shall  act  on  behalf  of  the  Revolving  Lenders  with  respect  to  any  Letters  of  Credit
issued  by  it  and  the  documents  associated  therewith,  and  such  L/C  Issuer  shall  have  all  of  the  benefits  and
immunities  (A)  provided  to  the  Administrative  Agent  in  Article  IX  with  respect  to  any  acts  taken  or  omissions
suffered by such L/C Issuer in connection with Letters of Credit issued by it or proposed to be issued by it and Issuer
Documents pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article IX
included such L/C Issuer with respect to such acts or omissions, and (B) as additionally provided herein with respect
to the L/C Issuers.

(b)    Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension Letters of Credit.

(i)    Each Letter of Credit shall be issued or amended, as the case may be, upon the request of a Borrower
delivered to the applicable  L/C  Issuer  (with  a  copy  to  the  Administrative  Agent) in the form of a Letter of Credit
Application,  appropriately  completed  and  signed  by  a  Responsible  Officer  of  such  Borrower  and/or  its  Restricted
Subsidiary, as required by such L/C Issuer. Such Letter of Credit Application may be sent by facsimile, by mail, by
overnight  courier,  by  electronic  transmission  using  the  system  provided  by  the  applicable  L/C  Issuer,  by  personal
delivery or by any other means reasonably acceptable to such L/C Issuer. Such Letter of Credit Application must be
received  by  the  applicable  L/C  Issuer  and  the  Administrative  Agent  not  later  than  11:00  a.m.  at  least  five  (5)
Business

Days (or such later date and time as the Administrative Agent and such L/C Issuer may agree in a particular instance
in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a
request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail
satisfactory  to  the  applicable  L/C  Issuer:  (A)  the  proposed  issuance  date  of  the  requested  Letter  of  Credit  (which
shall be a Business Day); (B) the amount and currency thereof and in the absence of specification of currency shall
be  deemed a request  for  a  Letter  of  Credit  denominated  in  Dollars;  (C)  the  expiry date thereof; (D) the name and
address  of  the  beneficiary  thereof;  (E)  the  documents  to  be  presented  by  such  beneficiary  in  case  of  any  drawing
thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder;
(G)  the  purpose  and  nature  of  the  requested  Letter  of  Credit;  and  (H)  such  other  matters  as  such  L/C  Issuer  may
reasonably require. In  the  case  of  a  request  for  an  amendment  of  any  outstanding  Letter  of  Credit,  such  Letter  of
Credit Application shall specify in form and detail reasonably satisfactory to the applicable L/C Issuer: (1) the Letter
of Credit to be amended; (2) the proposed date of amendment thereof (which shall be a Business Day); (3) the nature
of the proposed amendment; and (4) such other matters as such L/C Issuer may require. Additionally, the Borrowers
shall  furnish  to  the  applicable  L/C  Issuer  and  the  Administrative  Agent  such  other  documents  and  information
pertaining to such requested Letter of Credit issuance or amendment, including any Issuer Documents, as such L/C
Issuer or the Administrative Agent may require.

(ii)    Promptly after receipt of any Letter of Credit Application, the applicable L/C Issuer will confirm with
the  Administrative  Agent  (by  telephone  or  in  writing)  that  the  Administrative  Agent  has  received  a  copy  of  such
Letter  of  Credit  Application  from  the  applicable  Borrower  and,  if  not,  such  L/C  Issuer  will  provide  the
Administrative  Agent  with  a  copy  thereof.  Unless  the  applicable  L/C  Issuer  has  received  written  notice  from  any
Revolving Lender, the Administrative Agent or any Loan Party, at least one (1) Business Day prior to the requested
date of issuance or amendment of the applicable Letter of Credit, that one or more applicable conditions contained in
Article IV shall not then be satisfied, then, subject to the terms and conditions hereof, such L/C Issuer shall, on the
requested  date,  issue  a  Letter  of  Credit  for  the  account  of  the  applicable  Borrower  (or  its  applicable  Restricted
Subsidiary) or enter into the applicable amendment, as the case may be, in each case in accordance with such L/C
Issuer’s  usual  and  customary  business  practices.  Immediately  upon  the  issuance  of  each  Letter  of  Credit,  each
Revolving  Lender  shall  be  deemed  to,  and  hereby  irrevocably  and  unconditionally  agrees  to,  purchase  from  the
applicable  L/C  Issuer  a  risk  participation  in  such  Letter  of  Credit  in  an  amount  equal  to  the  product  of  such
Revolving  Lender’s  Applicable  Revolving  Percentage  (determined  without  regard  to  any  Class  or  Classes  of
Revolving Commitments of such Lender) times the amount of such Letter of Credit.

(iii)        Promptly  after  its  delivery  of  any  Letter  of  Credit  or  any  amendment  to  a  Letter  of  Credit  to  an
advising  bank  with  respect  thereto  or  to  the  beneficiary  thereof,  the  applicable  L/C  Issuer  will  also  deliver  to  the
Company and the Administrative Agent a true and complete copy of such Letter of Credit or amendment.

(iv)        If  the  applicable  Borrower  so  requests  in  any  applicable  Letter  of  Credit  Application  (or  the
amendment of an outstanding Letter of Credit), the applicable L/C Issuer may, in its sole discretion, agree to issue a
standby  Letter  of  Credit  that  has  automatic  extension  provisions  (each,  an  “Auto-Extension  Letter  of  Credit”);
provided that any such Auto-Extension Letter of Credit must permit such L/C Issuer to prevent any such extension at
least  once  in  each  twelve  (12)  month  period  (commencing  with  the  date  of  issuance  of  such  Letter  of  Credit)  by
giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such
twelve (12) month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by
the applicable L/C Issuer, the applicable Borrower shall not be required to make a specific request to such L/C Issuer
for any such extension. Once  an  Auto-Extension  Letter  of  Credit  has  been  issued,  the  Revolving  Lenders  shall  be
deemed to have authorized (but may not require) the applicable L/C Issuer to permit the extension of such Letter of
Credit  at  any  time  to  an  expiry  date  not  later  than  the  Letter  of  Credit  Expiration  Date;  provided  that,  a  Letter  of
Credit  may,  upon  the  request  of  the  applicable  Borrower,  be  renewed  for  a  period  beyond  the  Letter  of  Credit
Expiration Date subject to the provisions of Section 2.03(a)(ii)(B); provided, however, that such L/C Issuer shall not
permit any such extension if (A) such L/C Issuer has determined that it would not be permitted, or would have no
obligation at such time  to  issue  such  Letter  of  Credit  in  its  revised  form  (as  extended) under the terms hereof (by
reason of the provisions of clause (ii) or (iii) of Section 2.03(a) or otherwise), or (B) it has received notice (which
may be by telephone or in writing) on or before the day that is seven (7) Business Days before the Non-Extension
Notice Date (1) from the Administrative Agent that the Required Lenders have elected not to permit such extension
or  (2)  from  the  Administrative  Agent,  any  Revolving  Lender  or  any  Borrower  that  one  or  more  of  the  applicable
conditions  specified  in  Section  4.02  is  not  then  satisfied,  and  in  each  such  case  directing  such  L/C  Issuer  not  to
permit such extension.

(c)    Drawings and Reimbursements; Funding of Participations.

(i)    Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of
Credit, the applicable L/C Issuer shall notify the applicable Borrower and the Administrative Agent thereof; provided
that any failure to give or delay in giving such notice shall not relieve the applicable Borrower of its obligation to
reimburse such L/C Issuer and the Lenders with respect to any drawing under any Letter of Credit. The applicable

Borrower shall reimburse the applicable L/C Issuer for all drawings under any Letter of Credit in Dollars, unless, in
the case of a Letter of Credit denominated in an Alternative Currency, (A) such L/C Issuer (at its option) shall have
specified in such notice that it will require reimbursement in such Alternative Currency, or (B) in the absence of any
such requirement for reimbursement in such Alternative Currency, the applicable Borrower shall have notified such
L/C Issuer promptly following receipt of the notice of drawing that such Borrower will reimburse such L/C Issuer in
such Alternative Currency. In the case of any such reimbursement in Dollars of a drawing under a Letter of Credit
denominated in an Alternative Currency, the applicable L/C Issuer shall notify the applicable Borrower of the Dollar
Equivalent of the amount of the drawing promptly following the determination thereof. If such Borrower shall have
received  such  notice  from  the  applicable  L/C  Issuer  on  or  prior  to  11:00  a.m.  on  the  date  of  payment  by  the
applicable L/C Issuer under a Letter of Credit to be reimbursed in Dollars, not later than 4:00 p.m. on such date of
payment by the applicable L/C Issuer, or, if such Borrower shall have received such notice later than 11:00 a.m. on
the date of payment by the applicable L/C Issuer under a Letter of Credit to be reimbursed in Dollars, not later than
11:00 a.m. on the immediately following Business Day, or the Applicable Time on the date of any payment by such
L/C Issuer under a Letter of Credit to be reimbursed in an Alternative Currency (each such date, an “Honor Date”),
the applicable Borrower shall reimburse such L/C Issuer through the Administrative Agent in an amount equal to the
amount  of  such  drawing  and  in  the  applicable  currency.  In  the  event  that  (A)  a  drawing  denominated  in  an
Alternative  Currency  is  to  be  reimbursed  in  Dollars  and  (B)  the  Dollar  amount  paid  by  the  applicable  Borrower,
whether on or after the Honor Date, shall not be adequate on the date of that payment to purchase in accordance with
normal  banking  procedures  a  sum  denominated  in  the  Alternative  Currency  equal  to  the  drawing,  such  Borrower
agrees, as a separate and independent obligation, to indemnify the applicable L/C Issuer for the loss resulting from its
inability on that date to purchase the Alternative Currency in the full amount of the drawing. If such Borrower fails
to so reimburse such L/C Issuer by such time, the Administrative Agent shall promptly notify each Revolving Lender
of the Honor Date, the amount of the unreimbursed drawing (expressed in Dollars in an amount equal to the Dollar
Equivalent  thereof  in  the  case  of  a  Letter  of  Credit  denominated  in  an  Alternative  Currency)  (the  “Unreimbursed
Amount”), and the amount of such Revolving Lender’s Applicable Revolving Percentage thereof. In such event, the
Borrowers  shall  be  deemed  to  have  requested  a  Revolving  Borrowing  of  Base  Rate  Loans  to  be  disbursed  on  the
Honor  Date  in  an  amount  equal  to  the  Unreimbursed  Amount,  without  regard  to  the  minimum  and  multiples
specified in Section 2.02 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized
portion of the Revolving Commitments and the conditions set forth in Section 4.02 (other than the delivery of a Loan
Notice). Any notice given by any L/C Issuer or the Administrative Agent pursuant to this Section 2.03(c)(i) may be
given by telephone if immediately confirmed in writing;

provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such
notice.

(ii)    Each Revolving Lender shall upon any notice pursuant to Section 2.03(c)(i) make funds available (and
the Administrative Agent may apply Cash Collateral provided for this purpose) for the account of the applicable L/C
Issuer, in Dollars, at the Administrative Agent’s Office in an amount equal to its Applicable Revolving Percentage
(determined  without  regard  to  any  separate  Class  or  Classes  of  Revolving  Commitments  of  such  Lender)  of  the
Unreimbursed Amount not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative
Agent,  whereupon,  subject  to  the  provisions  of  Section  2.03(c)(iii),  each  Revolving  Lender  that  so  makes  funds
available  shall  be  deemed  to  have  made  a  Base  Rate  Loan  to  the  Company  in  such  amount.  The  Administrative
Agent shall remit the funds so received to the applicable L/C Issuer in Dollars.

(iii)    With respect to any Unreimbursed Amount that is not fully refinanced by a Revolving Borrowing of
Base  Rate  Loans  because  the  conditions  set  forth  in  Section  4.02  cannot  be  satisfied  or  for  any  other  reason,  the
applicable  Borrower  shall  be  deemed  to  have  incurred  from  the  applicable  L/C  Issuer  an  L/C  Borrowing  in  the
amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on
demand (together with interest) and shall bear interest at the Default Rate. In such event, each Revolving Lender’s
payment to the Administrative Agent for the account of the applicable L/C Issuer pursuant to Section 2.03(c)(ii) shall
be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from
such Lender in satisfaction of its participation obligation under this Section 2.03.

(iv)    Until each Revolving Lender funds its Revolving Loan or L/C Advance pursuant to this Section 2.03(c)
to reimburse the applicable L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such
Lender’s  Applicable  Revolving  Percentage  of  such  amount  shall  be  solely  for  the  account  of  the  applicable  L/C
Issuer.

(v)    Each Revolving Lender’s obligation to make Revolving Loans or L/C Advances to reimburse each L/C
Issuer  for  amounts  drawn  under  Letters  of  Credit,  as  contemplated  by  this  Section  2.03(c),  shall  be  absolute  and
unconditional  and  shall  not  be  affected  by  any  circumstance,  including  (A)  any  setoff,  counterclaim,  recoupment,
defense  or  other  right  which  such  Lender  may  have  against  any  L/C  Issuer,  any  Borrower,  any  Subsidiary  or  any
other Person for any reason whatsoever; (B) the occurrence or continuance of a Default; (C) any existing Class of
Revolving  Commitments  or  (D)  any  other  occurrence,  event  or  condition,  whether  or  not  similar  to  any  of  the
foregoing; provided, however,  that  each  Revolving  Lender’s  obligation  to  make  Revolving  Loans  pursuant  to  this
Section 2.03(c) is subject to the conditions set forth in Section 4.02 (other

than  delivery  by  the  Company  of  a  Loan  Notice).  No  such  making  of  an  L/C  Advance  shall  relieve  or  otherwise
impair  the  obligation  of  the  applicable  Borrower  to  reimburse  the  applicable  L/C  Issuer  for  the  amount  of  any
payment made by such L/C Issuer under any Letter of Credit, together with interest as provided herein.

(vi)        If  any  Revolving  Lender  fails  to  make  available  to  the  Administrative  Agent  for  the  account  of  the
applicable L/C Issuer any amount required to be paid by such Lender pursuant to the foregoing provisions of this
Section  2.03(c)  by  the  time  specified  in  Section  2.03(c)(ii),  then,  without  limiting  the  other  provisions  of  this
Agreement, such L/C Issuer shall be entitled to recover from such Lender (acting through the Administrative Agent),
on demand, such amount with interest thereon for the period from the date such payment is required to the date on
which  such  payment  is  immediately  available  to  such  L/C  Issuer  at  a  rate  per  annum  equal  to  the  applicable
Overnight Rate from time to time in effect, plus any administrative, processing or similar fees customarily charged
by  such  L/C  Issuer  in  connection  with  the  foregoing.  If  such  Lender  pays  such  amount  (with  interest  and  fees  as
aforesaid),  the  amount  so  paid  shall  constitute  such  Lender’s  Revolving  Loan  included  in  the  relevant  Revolving
Borrowing or L/C Advance in respect of the relevant L/C Borrowing, as the case may be. A certificate of any L/C
Issuer submitted to  any  Revolving  Lender  (through  the  Administrative  Agent) with respect to any amounts owing
under this Section 2.03(c)(vi) shall be conclusive absent manifest error.

(d)    Repayment of Participations.

(i)    At any time after any L/C Issuer has made a payment under any Letter of Credit and has received from
any Revolving Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.03(c), if
the  Administrative  Agent  receives  for  the  account  of  such  L/C  Issuer  any  payment  in  respect  of  the  related
Unreimbursed  Amount  or  interest  thereon  (whether  directly  from  the  applicable  Borrower  or  otherwise,  including
proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to
such Lender its Applicable Revolving Percentage thereof in Dollars and in the same funds as those received by the
Administrative Agent.

(ii)        If  any  payment  received  by  the  Administrative  Agent  for  the  account  of  the  applicable  L/C  Issuer
pursuant to Section 2.03(c)(i) is required to be returned under any of the circumstances described in Section 11.05
(including pursuant to any settlement entered into by such L/C Issuer in its discretion), each Revolving Lender shall
pay  to  the  Administrative  Agent  for  the  account  of  the  applicable  L/C  Issuer  its  Applicable  Revolving  Percentage
thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such
amount is returned by such Lender, at a rate per annum equal to the applicable Overnight Rate from time to time in
effect. The obligations of the

Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

(e)        Obligations  Absolute.  The  obligation  of  each  applicable  Borrower  to  reimburse  each  L/C  Issuer  for  each
drawing under each Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and
shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following:

(i)        any  lack  of  validity  or  enforceability  of  such  Letter  of  Credit,  this  Agreement,  or  any  other  Loan

Document;

(ii)        the  existence  of  any  claim,  counterclaim,  setoff,  defense  or  other  right  that  any  Borrower  or  any
Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for
whom any such beneficiary or any such transferee may be acting), any L/C Issuer or any other Person, whether in
connection with this Agreement or by such Letter of Credit, the transactions contemplated hereby or any agreement
or instrument relating thereto, or any unrelated transaction;

(iii)    any draft, demand, endorsement, certificate or other document presented under or in connection with
such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein
being  untrue  or  inaccurate  in  any  respect;  or  any  loss  or  delay  in  the  transmission  or  otherwise  of  any  document
required in order to make a drawing under such Letter of Credit;

(iv)    waiver by any L/C Issuer of any requirement that exists for such L/C Issuer’s protection and not the
protection  of  any  Borrower  or  any  waiver  by  such  L/C  Issuer  which  does  not  in  fact  materially  prejudice  the
Borrowers;

(v)        honor  of  a  demand  for  payment  presented  electronically  even  if  such  Letter  of  Credit  requires  that

demand be in the form of a draft;

(vi)    any payment made by any L/C Issuer in respect of an otherwise complying item presented after the
date specified as the expiration date of, or the date by which documents must be received under, such Letter of Credit
if presentation after such date is authorized by the UCC, the ISP or the UCP, as applicable;

(vii)    any payment by any L/C Issuer under such Letter of Credit against presentation of a draft or certificate
that does not strictly comply with the terms of such Letter of Credit; or any payment made by such L/C Issuer under
such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the
benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of
such Letter

of Credit, including any arising in connection with any proceeding under any Debtor Relief Law;

(viii)        any  other  circumstance  or  happening  whatsoever,  whether  or  not  similar  to  any  of  the  foregoing,
including  any  other  circumstance  that  might  otherwise  constitute  a  defense  available  to,  or  a  discharge  of,  any
Borrower or any of its Subsidiaries; or

(ix)        any  adverse  change  in  the  relevant  exchange  rates  or  in  the  availability  of  the  relevant  Alternative

Currency to any Borrower or any Subsidiary or in the relevant currency markets generally;

provided  that  the  foregoing  shall  not  excuse  any  L/C  Issuer  from  liability  to  the  Borrowers  to  the  extent  provided  in  the  second
proviso to Section 2.03(f).

The  applicable  Borrower  shall  promptly  examine  a  copy  of  each  Letter  of  Credit  and  each  amendment  thereto  that  is
delivered to it and, in the event of any claim of noncompliance with any of such Borrower’s instructions or other irregularity, such
Borrower will immediately notify the applicable L/C Issuer. The Borrowers shall be conclusively deemed to have waived any such
claim against the applicable L/C Issuer and its correspondents unless such notice is given as aforesaid.

(f)    Role of L/C Issuers. Each Lender and each Borrower agree that, in paying any drawing under a Letter of Credit,
the  applicable  L/C  Issuer  shall  not  have  any  responsibility  to  obtain  any  document  (other  than  any  sight  or  time  draft,
certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy
of any such document or the authority of the Person executing or delivering any such document. None of the L/C Issuers,
the Administrative Agent, any of their respective Related Parties nor any correspondent, participant or assignee of any L/C
Issuer  shall  be  liable  to  any  Lender  for  (i)  any  action  taken  or  omitted  in  connection  herewith  at  the  request  or  with  the
approval  of  the  Lenders  or  the  Required  Lenders,  as  applicable;  (ii)  any  action  taken  or  omitted  in  the  absence  of  gross
negligence,  willful  misconduct  or  bad  faith;  or  (iii)  the  due  execution,  effectiveness,  validity  or  enforceability  of  any
document or instrument related to any Letter of Credit or Issuer Document. The Borrowers hereby assume all risks of the
acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this
assumption  is  not  intended  to,  and  shall  not,  preclude  the  Borrowers’  pursuing  such  rights  and  remedies  as  it  may  have
against the beneficiary or transferee at law or under any other agreement. None of the L/C Issuers, the Administrative Agent,
any  of  their  respective  Related  Parties  nor  any  correspondent,  participant  or  assignee  of  any  L/C  Issuer  shall  be  liable  or
responsible  for  any  of  the  matters  described  in  Section  2.03(e);  provided,  however,  that  anything  in  such  clauses  to  the
contrary notwithstanding, the Borrowers may have a claim against any L/C Issuer, and such L/C Issuer may be liable to the
Borrowers,  to  the  extent,  but  only  to  the  extent,  of  any  direct,  as  opposed  to  consequential,  special,  indirect,  punitive  or
exemplary, damages suffered by the Borrowers which the Borrowers prove, as determined by a final nonappealable

judgment of a court of competent jurisdiction, were caused by such L/C Issuer’s gross negligence, willful misconduct or bad
faith or such L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a
sight or time draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and
not in limitation of the foregoing, any L/C Issuer may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or information to the contrary, and no L/C Issuer shall be
responsible  for  the  validity  or  sufficiency  of  any  instrument  transferring,  endorsing  or  assigning  or  purporting  to  transfer,
endorse or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may
prove to be invalid or ineffective for any reason. Any L/C Issuer may send a Letter of Credit or conduct any communication
to  or  from  the  beneficiary  via  the  Society  for  Worldwide  Interbank  Financial  Telecommunication  (“SWIFT”)  message  or
overnight courier, or any other commercially reasonable means of communicating with a beneficiary.

(g)    Applicability of ISP and UCP; Limitation of Liability. Unless otherwise expressly agreed by the applicable L/C
Issuer and the applicable Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing
Letter of Credit), (i) the rules of the ISP shall apply to each standby Letter of Credit and (ii) the rules of the UCP shall apply
to each commercial Letter of Credit. Notwithstanding the foregoing, no L/C Issuer shall be responsible to the Borrowers for,
and  no  L/C  Issuer’s  rights  and  remedies  against  the  Borrowers  shall  be  impaired  by,  any  action  or  inaction  of  such  L/C
Issuer  required  or  permitted  under  any  law,  order,  or  practice  that  is  required  or  permitted  to  be  applied  to  any  Letter  of
Credit  or  this  Agreement,  including  the  Law  or  any  order  of  a  jurisdiction  where  such  L/C  Issuer  or  the  beneficiary  is
located,  the  practice  stated  in  the  ISP  or  UCP,  as  applicable,  or  in  the  decisions,  opinions,  practice  statements,  or  official
commentary  of  the  ICC  Banking  Commission,  the  Bankers  Association  for  Finance  and  Trade  -  International  Financial
Services Association (BAFT-IFSA), or the Institute of International Banking Law & Practice, whether or not any Letter of
Credit chooses such law or practice.

(h)    Letter of Credit Fees. The applicable Borrowers shall pay to the Administrative Agent for the account of each
Revolving Lender in accordance, subject to Section 2.15, with its Applicable Revolving Percentage a Letter of Credit fee
(the “Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Rate times the Dollar Equivalent of the daily
amount available to  be  drawn  under  such  Letter  of  Credit. Letter of Credit Fees shall be (1) due and payable on the first
Business  Day  following  each  fiscal  quarter  end,  commencing  with  the  first  such  date  to  occur  after  the  issuance  of  such
Letter of Credit on the Letter of Credit Expiration Date and thereafter on demand and (2) computed on a quarterly basis in
arrears.

(i)    Fronting Fee and Documentary and Processing Charges Payable to L/C Issuers. The applicable Borrowers shall
pay  directly  to  the  applicable  L/C  Issuer  for  its  own  account  a  fronting  fee  (i)  with  respect  to  each  commercial  Letter  of
Credit, at a rate

per annum equal to 0.125% (or such other rate separately agreed between the applicable Borrowers and the L/C Issuers),
computed on the Dollar Equivalent of the amount of such Letter of Credit, and payable upon the issuance thereof, (ii) with
respect  to  any  amendment  of  a  commercial  Letter  of  Credit  increasing  the  amount  of  such  Letter  of  Credit,  at  a  rate
separately agreed between the applicable Borrowers and such L/C Issuer, computed on the Dollar Equivalent of the amount
of  such  increase,  and  payable  upon  the  effectiveness  of  such  amendment,  and  (iii)  with  respect  to  each  standby  Letter  of
Credit, at a rate per annum equal to 0.125% (or such other rate separately agreed between the applicable Borrowers and the
L/C Issuers), computed on the Dollar Equivalent of the daily amount available to be drawn under such Letter of Credit on a
quarterly basis in arrears. Such fronting fee shall be due and payable on or prior to the date that is ten (10) Business Days
following each fiscal quarter end, commencing with the first such date to occur after the issuance of such Letter of Credit,
on the Letter of Credit Expiration Date and thereafter on demand. For purposes of computing the daily amount available to
be drawn under any Letter of Credit, the amount of such Letter of Credit shall be determined in accordance with Section
1.06. In addition, the applicable Borrowers shall pay directly to the applicable L/C Issuer for its own account, in Dollars, the
customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of such L/C
Issuer relating to letters of credit as from time to time in effect. Such customary fees and standard costs and charges are due
and payable on demand and are nonrefundable.

(j)    Conflict  with  Issuer  Documents. In  the  event  of  any  conflict  between  the  terms  hereof  and  the  terms  of  any

Issuer Document, the terms hereof shall control.

(k)    L/C Issuer Reports to the Administrative Agent. Unless otherwise agreed by the Administrative Agent, each
L/C  Issuer  shall,  in  addition  to  its  notification  obligations  set  forth  elsewhere  in  this  Section,  provide  the  Administrative
Agent a Letter of Credit Report, as set forth below:

(i)    reasonably prior to the time that such L/C Issuer issues, amends, renews, increases or extends a Letter of
Credit, the date of such issuance, amendment, renewal, increase or extension and the stated amount of the applicable
Letters  of  Credit  after  giving  effect  to  such  issuance,  amendment,  renewal  or  extension  (and  whether  the  amounts
thereof shall have changed);

(ii)    on each Business Day on which such L/C Issuer makes a payment pursuant to a Letter of Credit, the

date and amount of such payment;

(iii)    on any Business Day on which any applicable Borrower fails to reimburse a payment made pursuant to
a Letter of Credit required to be reimbursed to such L/C Issuer on such day, the date of such failure and the amount
of such payment;

(iv)        on  any  other  Business  Day,  such  other  information  as  the  Administrative  Agent  shall  reasonably

request as to the Letters of Credit issued by such L/C Issuer; and

(v)    for so long as any Letter of Credit issued by an L/C Issuer is outstanding, such L/C Issuer shall deliver
to the Administrative Agent (A) on the last Business Day of each calendar month, (B) at all other times a Letter of
Credit Report is required  to  be  delivered  pursuant  to  this  Agreement,  and  (C)  on each date that (1) an L/C Credit
Extension occurs or (2) there is any expiration, cancellation and/or disbursement, in each case, with respect to any
such Letter of Credit, a Letter of Credit Report appropriately completed with the information for every outstanding
Letter of Credit issued by such L/C Issuer.

(l)    Additional L/C Issuers. Any Lender hereunder (that is reasonably acceptable to the Administrative Agent) may
become an L/C Issuer upon receipt by the Administrative Agent of a fully executed Notice of Additional L/C Issuer which
shall be signed by the Company, the Administrative Agent and each L/C Issuer.

(m)        Letters  of  Credit  Issued  for  Restricted  Subsidiaries.  Notwithstanding  that  a  Letter  of  Credit  issued  or
outstanding hereunder is in support of any obligations of, or is for the account of, a Restricted Subsidiary of any Borrower,
such  Borrower  shall  be  obligated  to  reimburse  each  L/C  Issuer  hereunder  for  any  and  all  drawings  under  each  Letter  of
Credit issued by such L/C Issuer. Each Borrower hereby acknowledges that the issuance of Letters of Credit for the account
of its Restricted Subsidiaries inures to the benefit of such Borrower, and that such Borrower’s business derives substantial
benefits from the businesses of such Restricted Subsidiaries.

2.04    Swingline Loans.

(a)    The Swingline. Subject to the terms and conditions set forth herein, the Swingline Lender, in reliance upon the
agreements of the other Lenders set forth in this Section, may in its sole discretion make loans to the Company (each such
loan, a “Swingline Loan”). Each such Swingline Loan may be made, subject to the terms and conditions set forth herein, to
the Company, in Dollars, from time to time on any Business Day during the Availability Period for any Class of Revolving
Commitments in which the Swingline Lender holds a Revolving Commitment, in an aggregate amount not to exceed at any
time  outstanding  the  amount  of  the  Swingline  Sublimit,  notwithstanding  the  fact  that  such  Swingline  Loans,  when
aggregated with the Applicable Revolving Percentage of the Outstanding Amount of Revolving Loans and L/C Obligations
of  the  Lender  acting  as  Swingline  Lender,  may  exceed  the  amount  of  such  Lender’s  Revolving  Commitment;  provided,
however,  that  (i)  after  giving  effect  to  any  Swingline  Loan,  (A)  the  Total  Revolving  Outstandings  shall  not  exceed  the
Aggregate Revolving Commitments at such time, (B) the Revolving Exposure of any Revolving Lender at such time shall
not  exceed  such  Lender’s  Revolving  Commitment,  and  (C)  the  Revolving  Exposure  of  any  Lender  under  any  Class  of
Revolving Commitments shall not exceed such Lender’s Revolving Commitment of such Class, (ii) the Company shall not
use the

proceeds of any Swingline Loan to refinance any outstanding Swingline Loan, and (iii) the Swingline Lender shall not be
under any obligation to make any Swingline Loan if it shall determine (which determination shall be conclusive and binding
absent manifest error) that it has, or by such Credit Extension may have, Fronting Exposure. Within the foregoing limits, and
subject to the other terms and conditions hereof, the Company may borrow under this Section, prepay under Section 2.05,
and  reborrow  under  this  Section.  Each  Swingline  Loan  shall  bear  interest  only  at  a  rate  based  on  the  Base  Rate  plus  the
Applicable Rate. Immediately upon the making of a Swingline Loan, each Revolving Lender shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan
in an amount equal to the product of such Revolving Lender’s Applicable Revolving Percentage (determined without regard
to any separate Class or Classes of Revolving Commitments of such Lender) times the amount of such Swingline Loan.

(b)    Borrowing Procedures.

Subject  to  the  terms  and  conditions  hereof,  each  Swingline  Borrowing  shall  be  made  upon  the  Company’s
irrevocable notice to the Swingline Lender and the Administrative Agent, which may be given by: (i) telephone or
(ii) a Swingline Loan Notice; provided that any telephonic notice must be confirmed immediately by delivery to the
Swingline Lender and the Administrative Agent of a Swingline Loan Notice. Each such Swingline Loan Notice must
be  received  by  the  Swingline  Lender  and  the  Administrative  Agent  not  later  than  1:00  p.m.  on  the  requested
borrowing date, and shall specify (A) the amount to be borrowed, which shall be a minimum of $100,000 and (B) the
requested date of the Borrowing (which shall be a Business Day). Promptly after receipt by the Swingline Lender of
any Swingline Loan Notice, the Swingline Lender will confirm with the Administrative Agent (by telephone or in
writing)  that  the  Administrative  Agent  has  also  received  such  Swingline  Loan  Notice  and,  if  not,  the  Swingline
Lender  will  notify  the  Administrative  Agent  (by  telephone  or  in  writing)  of  the  contents  thereof.  Unless  the
Swingline Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the
request of any Revolving Lender) prior to 2:00 p.m. on the date of the proposed Swingline Borrowing (1) directing
the Swingline Lender not to make such Swingline Loan as a result of the limitations set forth in the first proviso to
the thirdsecond sentence of Section 2.04(a), or (2) that one or more of the applicable conditions specified in Article
IV is not then satisfied, then, subject to the terms and conditions hereof, the Swingline Lender may, make the amount
of its Swingline Loan available to the Company at its office by crediting the account of the Company on the books of
the Swingline Lender in Same Day Funds.

(c)    Refinancing of Swingline Loans.

(i)    The Swingline Lender at any time in its sole discretion may request, on behalf of the Company (which

hereby irrevocably authorizes the

Swingline  Lender  to  so  request  on  its  behalf),  that  each  Revolving  Lender  make  a  Base  Rate  Loan  in  an  amount
equal  to  such  Lender’s  Applicable  Revolving  Percentage  (determined  without  regard  to  any  Class  or  Classes  of
Revolving Commitments of such Lender) of the amount of Swingline Loans then outstanding. Such request shall be
made in writing (which written request shall be deemed to be a Loan Notice for purposes hereof) and in accordance
with  the  requirements  of  Section  2.02,  without  regard  to  the  minimum  and  multiples  specified  therein  for  the
principal  amount  of  Base  Rate  Loans,  but  subject  to  the  unutilized  portion  of  the  Revolving  Facility  and  the
conditions set forth in Section 4.02. The Swingline Lender shall furnish the Company with a copy of the applicable
Loan Notice promptly after delivering such notice to the Administrative Agent. Each Revolving Lender shall make
an  amount  equal  to  its  Applicable  Revolving  Percentage  (determined  without  regard  to  any  Class  or  Classes  of
Revolving  Commitments  of  such  Lender)  of  the  amount  specified  in  such  Loan  Notice  available  to  the
Administrative Agent in Same Day Funds (and the Administrative Agent may apply Cash Collateral available with
respect  to  the  applicable  Swingline  Loan)  for  the  account  of  the  Swingline  Lender  at  the  Administrative  Agent’s
Office  for  Dollar-denominated  payments  not  later  than  1:00  p.m.  on  the  day  specified  in  such  Loan  Notice,
whereupon, subject to Section 2.04(c)(ii), each Revolving Lender that so makes funds available shall be deemed to
have made a Base Rate Loan to the Company in such amount. The Administrative Agent shall remit the funds so
received to the Swingline Lender.

(ii)        If  for  any  reason  any  Swingline  Loan  cannot  be  refinanced  by  such  a  Revolving  Borrowing  in
accordance with Section 2.04(c)(i), the request for Base Rate Loans submitted by the Swingline Lender as set forth
herein  shall  be  deemed  to  be  a  request  by  the  Swingline  Lender  that  each  of  the  Revolving  Lenders  fund  its  risk
participation in the relevant Swingline Loan and each Revolving Lender’s payment to the Administrative Agent for
the  account  of  the  Swingline  Lender  pursuant  to  Section  2.04(c)(i)  shall  be  deemed  payment  in  respect  of  such
participation.

(iii)        If  any  Revolving  Lender  fails  to  make  available  to  the  Administrative  Agent  for  the  account  of  the
Swingline  Lender  any  amount  required  to  be  paid  by  such  Lender  pursuant  to  the  foregoing  provisions  of  this
Section  2.04(c)  by  the  time  specified  in  Section  2.04(c)(i),  the  Swingline  Lender  shall  be  entitled  to  recover  from
such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period
from the date such payment is required to the date on which such payment is immediately available to the Swingline
Lender  at  a  rate  per  annum  equal  to  the  applicable  Overnight  Rate  from  time  to  time  in  effect,  plus  any
administrative,  processing  or  similar  fees  customarily  charged  by  the  Swingline  Lender  in  connection  with  the
foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute
such Lender’s Revolving Loan included in the relevant Revolving Borrowing or funded participation in the relevant
Swingline

Loan, as the case may be. A certificate of the Swingline Lender submitted to any Lender (through the Administrative
Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv)        Each  Revolving  Lender’s  obligation  to  make  Revolving  Loans  or  to  purchase  and  fund  risk
participations in Swingline Loans pursuant to this Section 2.04(c) shall be absolute and unconditional and shall not
be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which
such Lender may have against the Swingline Lender, any Borrower or any other Person for any reason whatsoever,
(B) the occurrence or continuance of a Default, (C) any Class of any such Loans or (D) any other occurrence, event
or  condition,  whether  or  not  similar  to  any  of  the  foregoing;  provided,  however,  that  each  Revolving  Lender’s
obligation  to  make  Revolving  Loans  pursuant  to  this  Section  2.04(c)  is  subject  to  the  conditions  set  forth  in
Section 4.02 (other than delivery by the Company of a Loan Notice). No  such  funding  of  risk  participations  shall
relieve  or  otherwise  impair  the  obligation  of  the  Company  to  repay  Swingline  Loans,  together  with  interest  as
provided herein.

(d)    Repayment of Participations.

(i)    At any time after any Revolving Lender has purchased and funded a risk participation in a Swingline
Loan, if the Swingline Lender receives any payment on account of such Swingline Loan, the Swingline Lender will
distribute to such Revolving Lender its Applicable Revolving Percentage (determined without regard to any separate
Class  or  Classes  of  Revolving  Commitments  of  such  Lender)  thereof  in  the  same  funds  as  those  received  by  the
Swingline Lender.

(ii)    If any payment received by the Swingline Lender in respect of principal or interest on any Swingline
Loan is required to be returned by the Swingline Lender under any of the circumstances described in Section 11.05
(including pursuant to any settlement entered into by the Swingline Lender in its discretion), each Revolving Lender
shall pay to the Swingline Lender its Applicable Revolving Percentage (determined without regard to any separate
Class or Classes of Revolving Commitments of such Lender) thereof on demand of the Administrative Agent, plus
interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the
applicable  Overnight  Rate.  The  Administrative  Agent  will  make  such  demand  upon  the  request  of  the  Swingline
Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the
termination of this Agreement.

(e)        Interest  for  Account  of  Swingline  Lender.  The  Swingline  Lender  shall  be  responsible  for  invoicing  the
Company for interest on the Swingline Loans. Until each Revolving Lender funds its Base Rate Loan or risk participation
pursuant to this Section to refinance such Revolving Lender’s Applicable Revolving Percentage of any Swingline

Loan, interest in respect of such Applicable Revolving Percentage shall be solely for the account of the Swingline Lender.

(f)        Payments  Directly  to  Swingline  Lender.  The  Company  shall  make  all  payments  of  principal  and  interest  in

respect of the Swingline Loans directly to the Swingline Lender.

2.05    Prepayments.

(a)    Optional.

(i)    The Borrowers may, upon notice to the Administrative Agent pursuant to delivery to the Administrative
Agent  of  a  Notice  of  Loan  Prepayment,  at  any  time  or  from  time  to  time  voluntarily  prepay  Revolving  Loans  in
whole or in part without premium or penalty subject to Section 3.05; provided that, unless otherwise agreed by the
Administrative Agent, (A) such notice must be received by the Administrative Agent not later than 11:00 a.m. (1)
three (3) Business Days prior to any date of prepayment of Eurocurrency Rate Loans denominated in Dollars, Euro
or  Sterling,  (2)  four  (4)  Business  Days  (or  five  (5),  in  the  case  of  prepayment  of  Loans  denominated  in  Special
Notice Currencies) prior to any date of prepayment of Eurocurrency Rate Loans denominated in other Alternative
Currencies, and (3) on the date of prepayment of Base Rate Loans; (B) any prepayment of Eurocurrency Rate Loans
shall  be  in  a  principal  amount  of  $5,000,000  or  a  whole  multiple  of  $1,000,000  in  excess  thereof;  and  (C)  any
prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess
thereof or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify
the date, the currency and amount of such prepayment and the Type(s) of Loans to be prepaid and, if Eurocurrency
Rate Loans are to be prepaid, the Interest Period(s) of such Loans. The Administrative Agent will promptly notify
each Appropriate Lender of its receipt of each such notice, and of the amount of such Lender’s ratable portion of
such  prepayment  (based  on  such  Lender’s  Applicable  Percentage).  If  such  notice  is  given  by  any  Borrower,  the
applicable Borrower shall make such prepayment and the payment amount specified in such notice shall be due and
payable  on  the  date  specified  therein;  provided,  that  any  notice  of  prepayment  may  state  that  such  notice  is
conditional  upon  the  effectiveness  of  any  facility  or  instrument  refinancing  all  or  a  portion  of  the  outstanding
Revolving  Commitments  or  upon  the  consummation  of  any  other  debt  or  equity  transaction  or  event  that  will
generate financing in connection therewith, in which case, such notice may be revoked by the applicable Borrower
(by  notice  to  the  Administrative  Agent  on  or  prior  to  the  specified  date)  if  such  condition  is  not  satisfied.  Any
prepayment  of  principal  shall  be  accompanied  by  all  accrued  interest  on  the  amount  prepaid,  together  with  any
additional amounts required pursuant to Section 3.05. Subject to Section 2.15, such prepayments shall be paid to the
Lenders in accordance with their respective Applicable Percentages.

(ii)    The Company may, upon notice to the Swingline Lender pursuant to delivery to the Swingline Lender
of  a  Notice  of  Loan  Prepayment  (with  a  copy  to  the  Administrative  Agent),  at  any  time  or  from  time  to  time,
voluntarily prepay Swingline Loans in whole or in part without premium or penalty; provided that, unless otherwise
agreed by the Swingline Lender, (A) such notice must be received by the Swingline Lender and the Administrative
Agent not later than 1:00 p.m. on the date of the prepayment, and (B) any such prepayment shall be in a minimum
principal  amount  of  $100,000  or  a  whole  multiple  of  $100,000  in  excess  hereof  (or,  if  less,  the  entire  principal
thereof then outstanding). Each such notice shall specify the date and amount of such prepayment. If such notice is
given by the Company, the Company shall make such prepayment and the payment amount specified in such notice
shall be due and payable on the date specified therein; provided, that any notice of prepayment may state that such
notice  is  conditional  upon  the  effectiveness  of  any  facility  or  instrument  refinancing  all  or  a  portion  of  the
outstanding Revolving Commitments or upon the consummation of any other debt or equity transaction or event that
will  generate  financing  in  connection  therewith,  in  which  case,  such  notice  may  be  revoked  by  the  Company  (by
notice  to  the  Administrative  Agent  on  or  prior  to  the  specified  date)  if  such  condition  is  not  satisfied.  Any
prepayment  of  principal  shall  be  accompanied  by  all  accrued  interest  on  the  amount  prepaid,  together  with  any
additional amounts required pursuant to Section 3.05.

(b)    Mandatory.

(i)        If  for  any  reason  the  Total  Revolving  Outstandings  at  any  time  exceed  the  Aggregate  Revolving
Commitment then in effect for the Revolving Facility at such time, the applicable Borrowers shall promptly (and in
any event, within one (1) Business Day) prepay Revolving Loans, Swingline Loans and L/C Borrowings (together
with all accrued but unpaid interest thereon) and/or Cash Collateralize the L/C Obligations in an aggregate amount
equal  to  such  excess;  provided,  however,  that  the  Borrowers  shall  not  be  required  to  Cash  Collateralize  the  L/C
Obligations pursuant to this Section 2.05(b)(i) unless, after the prepayment of the Revolving Loans and Swingline
Loans,  the  Total  Revolving  Outstandings  exceed  the  Aggregate  Revolving  Commitment  then  in  effect  for  the
Revolving  Facility  at  such  time;  provided further,  that  if  any  such  excess  shall  result  solely  from  a  change  in  the
applicable  exchange  rates  relating  to  Alternative  Currencies,  then  such  prepayment  and/or  Cash  Collateralization
shall  only  be  required  to  be  made  by  the  applicable  Borrowers  upon  three  (3)  Business  Days’  notice  from  the
Administrative Agent to the Company.

(ii)        If  the  Administrative  Agent  notifies  the  Company  at  any  time  that,  as  a  result  of  a  change  in  the
applicable exchange rates relating to Alternative Currencies, the Outstanding Amount of all L/C Obligations at such
time exceeds an amount equal to 105% of the Letter of Credit Sublimit then in effect, then, within, three (3) Business
Days after the Company’s receipt of such notice, the

applicable  Borrowers  shall  Cash  Collateralize  Letters  of  Credit  in  an  aggregate  amount  sufficient  to  reduce  such
Outstanding Amount as of such date of payment to an amount not to exceed 100% of the Letter of Credit Sublimit
then in effect.

(iii)        If  the  Administrative  Agent  notifies  the  Company  at  any  time  that,  as  a  result  of  a  change  in  the
applicable  exchange  rates  relating  to  Alternative  Currencies,  the  Total  Revolving  Outstandings  denominated  in
Alternative Currencies at such time exceeds an amount equal to 105% of the Alternative Currency Sublimit then in
effect,  then,  within  three  (3)  Business  Days  after  the  Company’s  receipt  of  such  notice,  the  applicable  Borrowers
shall prepay Revolving Loans and/or Cash Collateralize Letters of Credit, in each case denominated in Alternative
Currencies,  in  an  aggregate  amount  sufficient  to  reduce  Total  Revolving  Outstandings  denominated  in  Alternative
Currencies as of such date of payment to an amount not to exceed 100% of the Alternative Currency Sublimit then in
effect;  provided,  however,  that  the  Borrowers  shall  not  be  required  to  Cash  Collateralize  such  Letters  of  Credit
pursuant  to  this  Section  2.05(b)(iiiii)  unless,  after  the  prepayment  of  the  Revolving  Loans  denominated  in
Alternative  Currencies,  the  Total  Revolving  Outstandings  denominated  in  Alternative  Currencies  exceed  the
Alternative Currency Sublimit then in effect.

(iv)        Except  as  otherwise  provided  in  Section  2.15,  (A)  prepayments  of  the  Revolving  Facility  made
pursuant to Section 2.05(b)(i) (other than by provision of Cash Collateral) first, shall be applied ratably to the L/C
Borrowings  and  the  Swingline  Loans,  and  second,  shall  be  applied  to  the  outstanding  Revolving  Loans,  ratably
across each outstanding Class of Revolving Loans, and (B) prepayments of the Revolving Facility made pursuant to
Section 2.05(b)(iii) (other than by provision of Cash Collateral) shall be applied to the outstanding Revolving Loans
denominated in Alternative Currencies, ratably across each outstanding Class of Revolving Loans. Cash Collateral
provided pursuant to this Section 2.05(b) shall be applied in accordance with Section 2.14. Upon the drawing of any
Letter of Credit that has been Cash Collateralized, the funds held as Cash Collateral shall be applied (without any
further action by or notice to or from any Loan Party or any Defaulting Lender that has provided Cash Collateral) to
reimburse the applicable L/C Issuer or the Revolving Lenders, as applicable.

Within the parameters of the applications set forth above in Section 2.05(b), prepayments pursuant to Section 2.05(b)
shall be applied first to Base Rate Loans and then to Eurocurrency Rate Loans in direct order of Interest Period maturities.
All prepayments under Section 2.05(b) shall be subject to Section 3.05, but otherwise without premium or penalty, and shall
be accompanied by interest on the principal amount prepaid through the date of prepayment.

Notwithstanding  anything  to  the  contrary  in  this  Section  2.05,  no  prepayment  by  a  Designated  Foreign  Borrower
shall be used to pay or be applied against any Guaranteed Obligations of or attributable to any U.S. Loan Party (or any other
Domestic Subsidiary).

2.06    Termination or Reduction of Commitments.

(a)    Optional. The Company may, upon notice to the Administrative Agent, terminate the Revolving Facility, the
Letter of Credit Sublimit, the Swingline Sublimit or the Alternative Currency Sublimit, or from time to time permanently
reduce the Revolving Facility, the Letter of Credit Sublimit, the Swingline Sublimit or the Alternative Currency Sublimit;
provided that (i) any such notice shall be received by the Administrative Agent not later than 11:00 a.m. three (3) Business
Days  prior  to  the  date  of  termination  or  reduction,  (ii)  any  such  partial  reduction  shall  be  in  an  aggregate  amount  of
$5,000,000 or any whole multiple of $500,000 in excess thereof and (iii) the Company shall not terminate or reduce (A) the
Revolving  Facility  if,  after  giving  effect  thereto  and  to  any  concurrent  prepayments  hereunder,  the  Total  Revolving
Outstandings would exceed the Aggregate Revolving Commitments, (B) the Letter of Credit Sublimit if, after giving effect
thereto,  the  Outstanding  Amount  of  L/C  Obligations  not  fully  Cash  Collateralized  hereunder  would  exceed  the  Letter  of
Credit Sublimit, (C) the Swingline Sublimit if, after giving effect thereto and to any concurrent prepayments hereunder, the
Outstanding Amount of Swingline Loans would exceed the Swingline Sublimit, or (D) the Alternative Currency Sublimit if,
after giving effect thereto and to any concurrent prepayments hereunder, the Total Revolving Outstandings denominated in
Alternative Currencies would exceed the Alternative Currency Sublimit; and provided, further, that any notice of permanent
reduction  or  termination  may  state  that  such  notice  is  conditional  upon  the  effectiveness  of  any  facility  or  instrument
refinancing  all  or  a  portion  of  the  outstanding  Revolving  Commitments  or  upon  the  consummation  of  any  other  debt  or
equity transaction or event that will generate financing in connection therewith, in which case such notice may be revoked
by the Company (by notice to the Administrative Agent on or prior to the specified date) if such condition is not satisfied.

(b)        Mandatory.        If  after  giving  effect  to  any  reduction  or  termination  of  Revolving  Commitments  under  this
Section  2.06,  the  Letter  of  Credit  Sublimit,  the  Alternative  Currency  Sublimit  or  the  Swingline  Sublimit  exceeds  the
Aggregate  Revolving  Commitments  at  such  time,  the  Letter  of  Credit  Sublimit,  the  Alternative  Currency  Sublimit  or  the
Swingline Sublimit, as the case may be, shall be automatically reduced by the amount of such excess.

(c)    Application of Commitment Reductions; Payment of Fees. The Administrative Agent will promptly notify the
Lenders of any termination or reduction of the Letter of Credit Sublimit, the Alternative Currency Sublimit, the Swingline
Sublimit or the Revolving Commitment under this Section 2.06. Upon any reduction of the Revolving Commitments, the
Revolving  Commitment  of  each  Revolving  Lender  shall  be  reduced  on  a  pro  rata  basis  across  all  Classes  of  Revolving
Commitments by such Lender’s Applicable Revolving Percentage of such reduction amount. All fees in respect

of the Revolving Facility accrued until the effective date of any termination of the Revolving Facility shall be paid on the
effective date of such termination.

2.07    Repayment of Loans.

(a)    Revolving Loans. The applicable Borrowers shall repay to the relevant Revolving Lenders on the applicable
Maturity  Date  for  each  Class  of  Revolving  Loans  the  aggregate  principal  amount  of  all  Revolving  Loans  of  such  Class
outstanding  on  such  date  made  to  such  Borrower  (it  being  understood  and  agreed  that,  subject  to  the  other  terms  and
conditions hereof, the Borrowers may make Borrowings of Revolving Loans under any remaining Revolving Commitments
of any other Class to effect such repayment).

(b)    Swingline Loans. The Company shall repay each Swingline Loan on the earlier to occur of (i) the date ten (10)
Business  Days  after  such  Loan  is  made  (it  being  understood  that  the  Company  may  use  the  proceeds  of  a  Borrowing  of
Revolving  Loans  for  such  repayment,  subject  to  the  applicable  conditions  to  such  Borrowing  hereunder)  and  (ii)  the
latestLatest Maturity Date for any Class of Revolving Commitments maintained by the Swingline Lender (in its capacity as
a Revolving Lender).

(c)        Reallocation  of  Applicable  Percentages  after  Maturity.  Upon  the  occurrence  of  a  Maturity  Date  for  any
applicable  Class  of  Revolving  Loans,  the  relevant  Applicable  Percentages  with  respect  to  each  remaining  Class  of
Revolving  Commitments  shall  be  readjusted  without  any  further  action  or  consent  of  any  other  party  (calculated  without
regard to the Class of Revolving Commitments as to which the Maturity Date has occurred), to reflect the expiration of the
Class of Revolving Commitments as to which the Maturity Date has occurred.

2.08    Interest and Default Rate.

(a)    Interest. Subject  to  the  provisions  of  Section  2.08(b),  (i)  each  Eurocurrency  Rate  Loan  under  the  Revolving
Facility  shall  bear  interest  on  the  outstanding  principal  amount  thereof  for  each  Interest  Period  from  the  applicable
borrowing  date  at  a  rate  per  annum  equal  to  the  Eurocurrency  Rate  for  such  Interest  Period  plus  the  Applicable  Rate;
(ii) each Base Rate Loan under the Revolving Facility shall bear interest on the outstanding principal amount thereof from
the applicable borrowing date at a rate per annum equal to the Base Rate plus the Applicable Rate; and (iii) each Swingline
Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum
equal to the Base Rate plus the Applicable Rate. To the extent that any calculation of interest or any fee required to be paid
under this Agreement shall be based on (or result in) a calculation that is less than zero, such calculation shall be deemed
zero for purposes of this Agreement.

(b)    Default Rate.

(i)        Upon  the  occurrence  of  any  Event  of  Default  under  Section  8.01(a),  whether  at  stated  maturity,  by
acceleration or otherwise, all outstanding Obligations (including Letter of Credit Fees) shall accrue at a fluctuating
interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable Laws.

(ii)    Upon the occurrence of any Event of Default under Section 8.01(f) or Section 8.01(g), all outstanding
Obligations (including Letter of Credit Fees) shall accrue at a fluctuating interest rate per annum at all times equal to
the Default Rate to the fullest extent permitted by applicable Laws.

(iii)    Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due

and payable upon demand.

(c)    Interest Payments. Interest  on  each  Loan  shall  be  due  and  payable  in  arrears  on  each  Interest  Payment  Date
applicable  thereto  and  at  such  other  times  as  may  be  specified  herein.  Interest  hereunder  shall  be  due  and  payable  in
accordance  with  the  terms  hereof  before  and  after  judgment,  and  before  and  after  the  commencement  of  any  proceeding
under any Debtor Relief Law.

2.09    Fees.

In addition to certain fees described in subsections (h) and (i) of Section 2.03:

(a)        Commitment  Fee.  The  Company  shall  pay  to  the  Administrative  Agent  for  the  account  of  each  Revolving
Lender in accordance with its Applicable Revolving Percentage, a commitment fee in Dollars equal to the Applicable Rate
times the actual daily amount by which the Revolving Facility exceeds the sum of (i) the Outstanding Amount of Revolving
Loans  and  (ii)  the  Outstanding  Amount  of  L/C  Obligations,  subject  to  adjustment  as  provided  in  Section  2.15.  For  the
avoidance of doubt, the Outstanding Amount of Swingline Loans shall not be counted towards or considered usage of the
Revolving Facility for purposes of determining the commitment fee. The commitment fee shall be calculated quarterly in
arrears and shall accrue at all times during the Availability Period, including at any time during which one or more of the
conditions in Article IV is not met, and shall be due and payable quarterly in arrears on the third Business Day after the end
of each March, June, September and December, commencing with the first such date to occur after the Closing Date, and on
the last day of the Availability Period for the Revolving Facility. For purposes of calculating the commitment fee, if there is
any  change  in  the  Applicable  Rate  during  any  quarter,  the  actual  daily  amount  shall  be  computed  and  multiplied  by  the
Applicable Rate separately for each period during such quarter that such Applicable Rate was in effect.

(b)    Other Fees.

(i)    The applicable Borrowers shall pay to the Persons entitled thereto, for their own account, in Dollars, fees
in the amounts and at the times specified in the Fee Letter. Such fees shall be fully earned when paid and shall not be
refundable for any reason whatsoever.

(ii)        The  applicable  Borrowers  shall  pay  to  the  Lenders  and  the  Arrangers,  such  fees  as  shall  have  been
separately  agreed  upon  in  writing  and  disclosed  to  the  Administrative  Agent  in  the  amounts  and  at  the  times  so
specified. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever.

2.10    Computation of Interest and Fees; Retroactive Adjustments of Applicable Rate.

(a)    Computation of Interest and Fees. All computations of interest for Base Rate Loans (including Base Rate Loans
determined by reference to the Eurocurrency Rate) shall be made on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed. All other computations of fees and interest shall be made on the basis of a 360-day year and
actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365
day year), or, in the case of interest in respect of Loans denominated in Alternative Currencies as to which market practice
differs from the foregoing, in accordance with such market practice. Interest shall accrue on each Loan for the day on which
the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is
paid,  provided  that  any  Loan  that  is  repaid  on  the  same  day  on  which  it  is  made  shall,  subject  to  Section  2.12(a),  bear
interest  for  one  (1)  day.  Each  determination  by  the  Administrative  Agent  of  an  interest  rate  or  fee  hereunder  shall  be
conclusive  and  binding  for  all  purposes,  absent  manifest  error.  With  respect  to  all  Non-LIBOR  Quoted  Currencies,  the
calculation of the applicable interest rate shall be determined in accordance with market practice.

(b)    Financial Statement Adjustments or Restatements. If, as a result of any restatement of or other adjustment to
the financial statements of the Company and its Subsidiaries or for any other reason, the Company, or the Lenders determine
that (i) the Consolidated Leverage Ratio as calculated by the Company as of any applicable date was inaccurate and (ii) a
proper calculation of the Consolidated Leverage Ratio would have resulted in higher pricing for such period, the Borrowers
shall  retroactively  be  obligated  to  pay  to  the  Administrative  Agent  for  the  account  of  the  applicable  Lenders  or  the
applicable L/C Issuers, as the case may be, promptly on demand by the Administrative Agent (or, after the occurrence of an
actual or deemed entry of an order for relief with respect to any Borrower under the Bankruptcy Code of the United States,
automatically and without further action by the Administrative Agent, any Lender or any L/C Issuer), an amount equal to the
excess of the amount of interest and fees that should have been paid for such period over the amount of interest and fees
actually paid for such period. This paragraph shall not limit the rights of the Administrative Agent, any Lender or any L/C
Issuer, as the case may be, under any provision of this Agreement to payment of any

Obligations  hereunder  at  the  Default  Rate  or  under  Article  VIII.  The  Borrowers’  obligations  under  this  paragraph  shall
survive  the  termination  of  the  Aggregate  Revolving  Commitments  and  the  repayment  of  all  other  Obligations  hereunder.
Any  additional  interest  or  fees  under  this  Section  2.10(b)  shall  not  be  due  and  payable  until  a  demand  is  made  for  such
payment  by  the  Administrative  Agent  and  accordingly,  any  nonpayment  of  such  interest  or  fees  as  a  result  of  any  such
inaccuracy shall not constitute a Default (whether retroactively or otherwise), and none of such additional amounts shall be
deemed overdue or accrue interest at the Default Rate.

2.11    Evidence of Debt.

(a)        Maintenance of Accounts.  The  Credit  Extensions  made  by  each  Lender  shall  be  evidenced  by  one  or  more
accounts  or  records  maintained  by  such  Lender  and  by  the  Administrative  Agent  in  the  ordinary  course  of  business.  The
accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of
the  amount  of  the  Credit  Extensions  made  by  the  Lenders  to  the  Borrowers  and  the  interest  and  payments  thereon.  Any
failure  to  so  record  or  any  error  in  doing  so  shall  not,  however,  limit  or  otherwise  affect  the  obligation  of  the  Borrowers
hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and
records maintained by any Lender and the accounts and records of the Administrative Agent in respect of such matters, the
accounts and records  of  the  Administrative  Agent  shall  control  in  the  absence of manifest error. Upon  the  request  of  any
Lender  made  through  the  Administrative  Agent,  the  Borrowers  shall  execute  and  deliver  to  such  Lender  (through  the
Administrative Agent) a Revolving Note, which shall evidence such Lender’s Loans in addition to such accounts or records.
Each  Lender  may  attach  schedules  to  its  Revolving  Note  and  endorse  thereon  the  date,  Type  (if  applicable),  amount,
currency and maturity of its Loans and payments with respect thereto.

(b)    Maintenance of Records. In addition to the accounts and records referred to in Section 2.11(a), each Lender and
the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases
and sales by such Lender of participations in Letters of Credit and Swingline Loans. In the event of any conflict between the
accounts and records maintained by the Administrative Agent and the accounts and records of any Lender in respect of such
matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

2.12    Payments Generally; Administrative Agent’s Clawback.

(a)    General. All payments to be made by the Borrowers shall be made free and clear of and without condition or
deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein and except
with respect to principal of and interest on Loans denominated in an Alternative Currency, all payments by the Borrowers
hereunder shall be made to the Administrative Agent, for the account of the respective Lenders to which such payment is
owed, at the applicable Administrative Agent’s Office in Dollars and in Same Day Funds not later than 2:00 p.m.

on the date specified herein. Except as otherwise expressly provided herein, all payments by the Borrowers hereunder with
respect  to  principal  and  interest  on  Loans  denominated  in  an  Alternative  Currency  shall  be  made  to  the  Administrative
Agent, for the account of the respective Lenders to which such payment is owed, at the applicable Administrative Agent’s
Office  in  such  Alternative  Currency  and  in  Same  Day  Funds  not  later  than  the  Applicable  Time  specified  by  the
Administrative  Agent  on  the  dates  specified  herein.  Without  limiting  the  generality  of  the  foregoing,  the  Administrative
Agent  may  require  that  any  payments  due  under  this  Agreement  be  made  in  the  United  States.  If,  for  any  reason,  any
Borrower  is  prohibited  by  any  Law  from  making  any  required  payment  hereunder  in  an  Alternative  Currency,  such
Borrower shall make such payment in Dollars in the Dollar Equivalent of the Alternative Currency payment amount. The
Administrative  Agent  will  promptly  distribute  to  each  Appropriate  Lender  its  relevant  Applicable  Percentage  (or  other
applicable share (including on account of Extended Revolving Commitments) as provided herein) of such payment in like
funds  as  received  by  wire  transfer  to  such  Lender’s  Lending  Office.  All  payments  received  by  the  Administrative  Agent
(i)  after  2:00  p.m.,  in  the  case  of  payments  in  Dollars  or  (ii)  after  the  Applicable  Time  specified  by  the  Administrative
Agent, in the case of payments in an Alternative Currency, shall in each case be deemed received on the next succeeding
Business  Day  and  any  applicable  interest  or  fee  shall  continue  to  accrue.  Subject  to  Section  2.07(a)  and  as  otherwise
specifically provided for in this Agreement, if any payment to be made by a Borrower shall come due on a day other than a
Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in
computing interest or fees, as the case may be.

(b)    (i)    Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed date of any Borrowing of Eurocurrency Rate Loans (or, in the case of
any  Borrowing  of  Base  Rate  Loans,  prior  to  12:00  noon  on  the  date  of  such  Borrowing)  that  such  Lender  will  not  make
available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that
such Lender has made such share available on such date in accordance with Section 2.02 (or, in the case of a Borrowing of
Base  Rate  Loans,  that  such  Lender  has  made  such  share  available  in  accordance  with  and  at  the  time  required  by
Section  2.02)  and  may,  in  reliance  upon  such  assumption,  make  available  to  the  applicable  Borrower  a  corresponding
amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative
Agent, then the applicable Lender and the applicable Borrower severally agree to pay to the Administrative Agent forthwith
on demand such corresponding amount in Same Day Funds with interest thereon, for each day from and including the date
such amount is made available to the applicable Borrower to but excluding the date of payment to the Administrative Agent,
at  (A)  in  the  case  of  a  payment  to  be  made  by  such  Lender,  the  Overnight  Rate,  plus  any  administrative,  processing  or
similar  fees  customarily  charged  by  the  Administrative  Agent  in  connection  with  the  foregoing  and  (B)  in  the  case  of  a
payment  to  be  made  by  any  Borrower,  the  interest  rate  applicable  to  Base  Rate  Loans  or  in  the  case  of  Alternative
Currencies in accordance with such market practice, in each case as applicable. If the applicable

Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the
Administrative  Agent  shall  promptly  remit  to  the  applicable  Borrower  the  amount  of  such  interest  paid  by  the  applicable
Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Administrative Agent, then the
amount so paid shall constitute such Lender’s Loan included in such Borrowing. Any payment by the applicable Borrower
shall be without prejudice to any claim the applicable Borrower may have against a Lender that shall have failed to make
such payment to the Administrative Agent.

(ii)    Payments by Borrowers; Presumptions by Administrative Agent. Unless the Administrative Agent shall
have received notice from the Company prior to the date on which any payment is due to the Administrative Agent
for  the  account  of  the  Lenders  or  the  L/C  Issuers  hereunder  that  the  applicable  Borrower  will  not  make  such
payment,  the  Administrative  Agent  may  assume  that  the  Borrowers  have  made  such  payment  on  such  date  in
accordance  herewith  and  may,  in  reliance  upon  such  assumption,  distribute  to  the  Appropriate  Lenders  or  the
applicable L/C Issuers, as the case may be, the amount due. In such event, if any applicable Borrower has not in fact
made  such  payment,  then  each  of  the  Appropriate  Lenders  or  the  applicable  L/C  Issuers,  as  the  case  may  be,
severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender
or such L/C Issuer, in Same Day Funds with interest thereon, for each day from and including the date such amount
is distributed to it to but excluding the date of payment to the Administrative Agent, at the Overnight Rate.

A  notice  of  the  Administrative  Agent  to  any  Lender  or  the  Company  with  respect  to  any  amount  owing  under  this

subsection (b) shall be conclusive, absent manifest error.

(c)    Failure to Satisfy Conditions Precedent. If any Lender makes available to the Administrative Agent funds for
any Loan to be made by such Lender as provided in the foregoing provisions of this Article II, and such funds are not made
available to the Borrowers by the Administrative Agent because the conditions to the applicable Credit Extension set forth in
Article IV are not satisfied or waived in accordance with the terms hereof, the Administrative Agent shall return such funds
(in like funds as received from such Lender) to such Lender, without interest.

(d)    Obligations of Lenders Several. The obligations of the Lenders hereunder to make Revolving Loans, to fund
participations in Letters of Credit and Swingline Loans and to make payments pursuant to Section 11.04(c) are several and
not  joint.  The  failure  of  any  Lender  to  make  any  Loan,  to  fund  any  such  participation  or  to  make  any  payment  under
Section 11.04(c) on any date required hereunder shall not relieve any other Lender of its corresponding obligation to do so
on  such  date,  and  no  Lender  shall  be  responsible  for  the  failure  of  any  other  Lender  to  so  make  its  Loan,  to  purchase  its
participation or to make its payment under Section 11.04(c).

(e)    Funding Source. Nothing herein shall be deemed to obligate any Lender to obtain the funds for any Loan in any
particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for any
Loan in any particular place or manner.

(f)    Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Borrowing (other than Swingline
Borrowings) shall be made from the Appropriate Lenders, each payment of fees under Sections 2.09(a) and 2.03(h) and shall
be  made  for  account  of  the  Appropriate  Lenders,  and  each  termination  or  reduction  of  the  amount  of  the  Revolving
Commitments shall be applied to the respective Revolving Commitments of the Lenders, pro rata according to the amounts
of their respective Revolving Commitments; (ii) each Borrowing shall be allocated pro rata among the Lenders according to
the amounts of their respective Revolving Commitments (in the case of the making of Revolving Loans) or their respective
Loans that are to be included in such Borrowing (in the case of conversions and continuations of Loans); (iii) each payment
or  prepayment  of  principal  of  Loans  by  the  Borrowers  shall  be  made  for  account  of  the  Appropriate  Lenders  pro  rata  in
accordance with the respective unpaid principal amounts of the Loans held by them; and (iv) each payment of interest on
Loans by the Borrowers shall be made for account of the Appropriate Lenders pro rata in accordance with the amounts of
interest on such Loans then due and payable to the respective Appropriate Lenders.

2.13    Sharing of Payments by Lenders.

If  any  Lender  shall,  by  exercising  any  right  of  setoff  or  counterclaim  or  otherwise,  obtain  payment  in  respect  of
(a) Obligations in respect of the Revolving Facility due and payable to such Lender hereunder and under the other Loan Documents
at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such
Lender  at  such  time  to  (ii)  the  aggregate  amount  of  the  Obligations  in  respect  of  the  Revolving  Facility  due  and  payable  to  all
Lenders hereunder and under the other Loan Documents at such time) of payments on account of the Obligations in respect of the
Revolving Facility due and payable to all Lenders hereunder and under the other Loan Documents at such time obtained by all the
Lenders at such time or (b) Obligations in respect of any of the Revolving Facility owing (but not due and payable) to such Lender
hereunder and under the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the
amount  of  such  Obligations  owing  (but  not  due  and  payable)  to  such  Lender  at  such  time  to  (ii)  the  aggregate  amount  of  the
Obligations in respect of the Revolving Facility owing (but not due and payable) to all Lenders hereunder and under the other Loan
Documents at such time) of payments on account of the Obligations in respect of the Revolving Facility owing (but not due and
payable) to all Lenders hereunder and under the other Loan Documents at such time obtained by all of the Lenders at such time,
then, in each case under clauses (a) and (b) above, the Lender receiving such greater proportion shall (A) notify the Administrative
Agent of such fact, and (B) purchase (for cash at face value) participations in the Loans and subparticipations in L/C Obligations
and  Swingline  Loans  of  the  other  Lenders,  or  make  such  other  adjustments  as  shall  be  equitable,  so  that  the  benefit  of  all  such
payments shall be shared by the Lenders ratably in accordance with

the aggregate amount of Obligations in respect of the Revolving Facility then due and payable to the Lenders or owing (but not due
and payable) to the Lenders, as the case may be, provided that:

(1)        if  any  such  participations  or  subparticipations  are  purchased  and  all  or  any  portion  of  the  payment
giving  rise  thereto  is  recovered,  such  participations  or  subparticipations  shall  be  rescinded  and  the  purchase  price
restored to the extent of such recovery, without interest; and

(2)    the provisions of this Section shall not be construed to apply to (x) any payment made by or on behalf of
the Borrowers pursuant to and in accordance with the express terms of this Agreement (including the application of
funds arising from the existence of a Defaulting Lender or Extended Revolving Commitments), (y) the application of
Cash  Collateral  provided  for  in  Section  2.14,  or  (z)  any  payment  obtained  by  a  Lender  as  consideration  for  the
assignment  of  or  sale  of  a  participation  in  any  of  its  Loans  or  subparticipations  in  L/C  Obligations  or  Swingline
Loans to any assignee or participant, other than an assignment to any Loan Party or any Affiliate thereof (as to which
the provisions of this Section shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable Law, that any
Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Loan Party rights of setoff and
counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Loan Party in the amount of
such participation.

2.14    Cash Collateral.

(a)    Certain Credit Support Events. If (i) any L/C Issuer has honored any full or partial drawing request under any
Letter of Credit and such drawing has resulted in an L/C Borrowing, (ii) as of the Letter of Credit Expiration Date, any L/C
Obligation for any reason remains outstanding, (iii) any Borrower shall be required to provide Cash Collateral pursuant to
Section 2.05 or 8.02(c) or (iv) there shall exist a Defaulting Lender, the applicable Borrowers shall, solely with respect to
their  respective  outstanding  Letters  of  Credit  or  L/C  Borrowings,  as  applicable,  immediately  (in  the  case  of  clause  (iii)
above, except to the extent a longer period is provided under Section 2.05, as applicable) or within one (1) Business Day (in
all other cases) following any request by the Administrative Agent or any L/C Issuer, provide Cash Collateral in an amount
not less than the applicable Minimum Collateral Amount (determined in the case of Cash Collateral provided pursuant to
clause (iv) above, after giving effect to Section 2.15(a)(iv) and any Cash Collateral provided by such Defaulting Lender) or
the amount required pursuant to Section 2.05, as applicable.

(b)        Grant  of  Security  Interest.  Each  Borrower,  and  to  the  extent  provided  by  any  Defaulting  Lender,  such
Defaulting  Lender,  hereby  grants  to  (and  subjects  to  the  control  of)  the  Administrative  Agent,  for  the  benefit  of  the
Administrative Agent, the L/C Issuers and the Lenders, and agrees to maintain, a first priority security interest in all such

cash,  deposit  accounts  and  all  balances  therein,  and  in  all  proceeds  of  the  foregoing,  all  as  security  for  the  obligations  to
which such Cash Collateral may be applied pursuant to Section 2.14(c). If at any time the Administrative Agent determines
that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent or the L/C Issuers as
herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the applicable
Borrower or, to the extent provided by any Defaulting Lender, such Defaulting Lender, will, promptly upon demand by the
Administrative  Agent,  pay  or  provide  to  the  Administrative  Agent  additional  Cash  Collateral  in  an  amount  sufficient  to
eliminate such deficiency. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be
maintained in one or more blocked, interest bearing deposit accounts at Bank of America (it being understood and agreed
that Bank of America and the Administrative Agent make no warranty or guarantee as to the level of, or amount (if any) of,
interest with respect to such deposit account). The applicable Borrowers shall pay on demand therefor from time to time all
customary  account  opening,  activity  and  other  administrative  fees  and  charges  in  connection  with  the  maintenance  and
disbursement  of  Cash  Collateral.  Each  Designated  Foreign  Borrower  hereby  agrees  to  take  all  such  further  acts  and  to
execute, acknowledge, deliver, record, file and register such documents and instruments as the Administrative Agent may
reasonably require to carry out the provisions of this Section 2.14.

(c)    Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided
under any of this Section 2.14 or Sections 2.03, 2.05, 2.15 or 8.02 in respect of Letters of Credit shall be held and applied to
the satisfaction of the specific L/C Obligations, obligations to fund participations therein (including, as to Cash Collateral
provided by a Revolving Lender that is a Defaulting Lender, any interest accrued on such obligation) and other obligations
for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein;
provided that no Cash Collateral provided in respect of any Obligations of a Designated Foreign Borrower shall be applied
to  the  satisfaction  of  any  Obligations  of  or  attributable  to  any  U.S.  Loan  Party;  provided  further,  however,  that  the
Borrowers  shall  cause  Cash  Collateral  to  be  provided  by  each  applicable  Borrower  in  an  amount  sufficient  to  Cash
Collateralize the L/C Obligations related to such Borrower, as provided herein.

(d)    Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or to secure
other  obligations  shall  be  released  promptly  following  (i)  the  elimination  of  the  applicable  Fronting  Exposure  or  other
obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Revolving Lender
(or,  as  appropriate,  its  assignee  following  compliance  with  Section  11.06(b)(vi)))  or  (ii)  the  determination  by  the
Administrative  Agent  and  the  applicable  L/C  Issuer  that  there  exists  excess  Cash  Collateral;  provided,  however,  (A)  any
such  release  shall  be  without  prejudice  to,  and  any  disbursement  or  other  transfer  of  Cash  Collateral  shall  be  and  remain
subject to, any other Lien conferred under the Loan Documents and the other applicable provisions of the Loan Documents,
and (B) the

Person  providing  Cash  Collateral  and  the  applicable  L/C  Issuer  may  agree  that  Cash  Collateral  shall  not  be  released  but
instead held to support future anticipated Fronting Exposure or other obligations.

(e)        Release  of  Lenders’  Obligations. Notwithstanding  anything  to  the  contrary  contained  herein  or  in  any  other
Loan Document, in the event that (i) any applicable L/C Issuer shall have issued, in accordance with Section 2.03(a)(ii)(B),
a Letter of Credit with an expiry date occurring after the Letter of Credit Expiration Date and (ii) the Borrowers shall have
Cash  Collateralized  the  Outstanding  Amount  of  all  such  L/C  Obligations  in  respect  of  such  Letter  of  Credit  pursuant  to
Section  2.14(a)  above,  then,  upon  the  provision  of  such  Cash  Collateral  and  without  any  further  action,  each  Lender
hereunder shall be automatically released from any further obligation to such L/C Issuer in respect of such Letter of Credit,
including, without limitation, any obligation of any such Lender to reimburse such L/C Issuer for amounts drawn under such
Letter of Credit or to purchase any risk participation therein; provided, however,  that  all  such  obligations  of  each  Lender
hereunder  to  such  L/C  Issuer  in  respect  of  such  Letter  of  Credit  shall  be  revived  if  any  Cash  Collateral  provided  by  the
Borrowers in respect of such Letter of Credit is subsequently invalidated, declared to be fraudulent or preferential, set aside
or required (including pursuant to any settlement entered into by the Administrative Agent or such L/C Issuer) to be repaid
to  a  trustee,  receiver,  examiner  or  any  other  party,  in  connection  with  any  proceeding  under  any  Debtor  Relief  Laws  or
otherwise, all as if such Cash Collateral had not been provided. The obligations of the Lenders under this paragraph shall
survive the Facility Termination Date.

2.15    Defaulting Lenders.

(a)    Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a
Defaulting  Lender,  then,  until  such  time  as  that  Lender  is  no  longer  a  Defaulting  Lender,  to  the  extent  permitted  by
applicable Law:

(i)    Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment,
waiver  or  consent  with  respect  to  this  Agreement  shall  be  restricted  as  set  forth  in  the  definition  of  “Required
Lenders” and Section 11.01.

(ii)    Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the
Administrative  Agent  for  the  account  of  such  Defaulting  Lender  (whether  voluntary  or  mandatory,  at  maturity,
pursuant to Article VIII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to
Section 11.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows:
first,  to  the  payment  of  any  amounts  owing  by  such  Defaulting  Lender  to  the  Administrative  Agent  hereunder;
second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any L/C Issuer or
Swingline Lender hereunder; third, to Cash Collateralize each L/C Issuer’s Fronting Exposure with respect to such
Defaulting Lender in accordance with Section 2.14; fourth, as the

Company may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of
which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by
the  Administrative  Agent;  fifth,  if  so  determined  by  the  Administrative  Agent  and  the  Company,  to  be  held  in  a
deposit  account  and  released  pro  rata  in  order  to  (A)  satisfy  such  Defaulting  Lender’s  potential  future  funding
obligations with respect to Loans under this Agreement and (B) Cash Collateralize each L/C Issuer’s future Fronting
Exposure  with  respect  to  such  Defaulting  Lender  with  respect  to  future  Letters  of  Credit  issued  under  this
Agreement, in accordance with Section 2.14; sixth, to the payment of any amounts owing to the Lenders, the L/C
Issuers or Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender,
any  L/C  Issuer  or  the  Swingline  Lender  against  such  Defaulting  Lender  as  a  result  of  such  Defaulting  Lender’s
breach  of  its  obligations  under  this  Agreement;  seventh,  so  long  as  no  Default  or  Event  of  Default  exists,  to  the
payment  of  any  amounts  owing  to  the  Borrowers  as  a  result  of  any  judgment  of  a  court  of  competent  jurisdiction
obtained  by  the  Borrowers  against  such  Defaulting  Lender  as  a  result  of  such  Defaulting  Lender’s  breach  of  its
obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise as may be required under
the  Loan  Documents  in  connection  with  any  Lien  conferred  thereunder  or  directed  by  a  court  of  competent
jurisdiction; provided that if (1) such payment is a payment of the principal amount of any Loans or L/C Borrowings
in respect of which such Defaulting Lender has not fully funded its appropriate share, and (2) such Loans were made
or the related Letters of Credit were issued at a time when the conditions set forth in Section 4.02 were satisfied or
waived, such payment shall be applied solely to pay the Loans of, and L/C Obligations owed to, all Non-Defaulting
Lenders on a pro rata basis with respect to any applicable Class prior to being applied to the payment of any Loans
of,  or  L/C  Obligations  owed  to,  such  Defaulting  Lender  until  such  time  as  all  Classes  of  the  relevant  Classes  of
Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro
rata  in  accordance  with  the  Revolving  Commitments  (including  any  applicable  Class  of  Revolving  Commitments)
hereunder without giving effect to Section 2.15(a)(iv). Any payments, prepayments or other amounts paid or payable
to  a  Defaulting  Lender  that  are  applied  (or  held)  to  pay  amounts  owed  by  a  Defaulting  Lender  or  to  post  Cash
Collateral pursuant to this Section 2.15(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and
each Lender irrevocably consents hereto.

(iii)    Certain Fees.

(A)    Fees. No Defaulting Lender shall be entitled to receive any fee payable under Section 2.09(a)
for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to
pay any

such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B)    Letter of Credit Fees. Each Defaulting Lender shall be entitled to receive Letter of Credit Fees
for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable
Revolving  Percentage  of  the  stated  amount  of  Letters  of  Credit  for  which  it  has  provided  Cash  Collateral
pursuant to Section 2.14.

(C)    Defaulting Lender Fees. With respect to any fee payable under Section 2.09(a) or any Letter of
Credit  Fee  not  required  to  be  paid  to  any  Defaulting  Lender  pursuant  to  clause  (A)  or  (B)  above,  the
Borrowers  shall  (1)  pay  to  each  Non-Defaulting  Lender  that  portion  of  any  such  fee  otherwise  payable  to
such  Defaulting  Lender  with  respect  to  such  Defaulting  Lender’s  participation  in  L/C  Obligations  or
Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2)
pay to each L/C Issuer and Swingline Lender, as applicable, the amount of any such fee otherwise payable to
such Defaulting Lender to the extent allocable to such L/C Issuer’s or Swingline Lender’s Fronting Exposure
to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee.

(iv)        Reallocation  of  Applicable  Revolving  Percentages  to  Reduce  Fronting  Exposure. All  or  any  part  of
such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non-
Defaulting Lenders in accordance with their respective Applicable Revolving Percentages (calculated without regard
to such Defaulting Lender’s Revolving Commitment) but only to the extent that (x) such reallocation does not cause
the  aggregate  Revolving  Exposure  of  any  Non-Defaulting  Lender  to  exceed  such  Non-Defaulting  Lender’s
Revolving  Commitment  or  the  aggregate  Revolving  Exposure  of  any  Non-Defaulting  Lender  under  any  Class  of
Revolving Commitments to exceed such Non-Defaulting Lender’s Revolving Commitment of such Class and (y) no
Non-Defaulting  Lender  is  allocated  any  Class  of  Revolving  Commitments  which  it  does  not  maintain.  Subject  to
Section  11.20,  no  reallocation  hereunder  shall  constitute  a  waiver  or  release  of  any  claim  of  any  party  hereunder
against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a
Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v)    Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (a)(iv) above
cannot, or can only partially, be effected, the applicable Borrowers shall, without prejudice to any right or remedy
available  to  it  hereunder  or  under  applicable  Law,  (A)  first,  prepay  Swingline  Loans  in  an  amount  equal  to  the
Swingline Lender’s Fronting Exposure and

(B) second, Cash Collateralize each L/C Issuer’s Fronting Exposure in accordance with the procedures set forth in
Section 2.14.

(b)        Defaulting  Lender  Cure.  If  the  Company,  the  Administrative  Agent,  Swingline  Lender  and  the  L/C  Issuers
agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto,
whereupon  as  of  the  effective  date  specified  in  such  notice  and  subject  to  any  conditions  set  forth  therein  (which  may
include  arrangements  with  respect  to  any  Cash  Collateral),  that  Lender  will,  to  the  extent  applicable,  purchase  at  par  that
portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to
be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held
on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 2.15(a)
(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively
with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender;
and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from
Defaulting  Lender  to  Lender  will  constitute  a  waiver  or  release  of  any  claim  of  any  party  hereunder  arising  from  that
Lender’s having been a Defaulting Lender.

2.16    Designated Foreign Borrowers.

(a)    Initial Designated Foreign Borrowers. Effective as of the date hereof, Vertex Europe and Vertex Ireland shall
each be a “Designated Foreign Borrower” hereunder and may receive Loans and have Letters of Credit issued for its account
as a Designated Foreign Borrower on the terms and conditions set forth in this Agreement.

(b)        Additional  Designated  Foreign  Borrowers.  The  Company  may  at  any  time,  upon  not  less  than  fifteen  (15)
Business  Days’  notice  from  the  Company  to  the  Administrative  Agent  (or  such  shorter  period  as  may  be  agreed  by  the
Administrative  Agent  in  its  sole  discretion),  request  to  designate  any  additional  Restricted  Subsidiary  that  is  a  Foreign
Subsidiary  of  the  Company  (an  “Applicant  Foreign  Borrower”)  as  a  Designated  Foreign  Borrower  to  receive  Revolving
Loans  hereunder  by  delivering  to  the  Administrative  Agent  (which  shall  promptly  deliver  counterparts  thereof  to  each
Lender)  a  duly  executed  Designated  Foreign  Borrower  Request  and  Assumption  Agreement.  The  parties  hereto
acknowledge  and  agree  that  prior  to  any  Applicant  Foreign  Borrower  becoming  entitled  to  utilize  the  credit  facilities
provided  for  herein,  (i)  the  Administrative  Agent,  the  Lenders  and  the  L/C  Issuers  must  each  agree  to  such  Applicant
Foreign Borrower becoming a Designated Foreign Borrower (such consent not to be unreasonably withheld or delayed) and
(ii) the Administrative Agent, the Lenders and the L/C Issuers shall have received such supporting resolutions, incumbency
certificates, opinions of counsel and other documents or information reasonably requested (including, without limitation and
to the extent so requested, (x) to the extent any Applicant Foreign Borrower qualifies as a “legal entity customer” under the
Beneficial Ownership

Regulation, a Beneficial Ownership Certification and (y) any other documentation and information regarding such Applicant
Foreign Borrower reasonably requested by the Administrative Agent and the Lenders in order to comply with “know your
customer”  and  anti-money  laundering  rules  and  regulations),  in  form,  content  and  scope  reasonably  satisfactory  to  the
Administrative Agent, as may be required by the Administrative Agent, and Revolving Notes signed by such new Borrowers
to  the  extent  any  Lender  so  requires  (the  requirements  in  the  foregoing  clauses  (i)  and  (ii),  the  “Designated  Foreign
Borrower Requirements”). If the Designated Foreign Borrower Requirements are met, the Administrative Agent shall send a
Designated Foreign Borrower Notice to the Company, the Lenders and the L/C Issuers specifying the effective date upon
which  such  Applicant  Foreign  Borrower  shall  constitute  a  Designated  Foreign  Borrower  for  purposes  hereof,  whereupon
each  of  the  Lenders  and  L/C  Issuers  agrees  to  permit  such  Designated  Foreign  Borrower  to  receive  Credit  Extensions
hereunder,  on  the  terms  and  conditions  set  forth  herein,  and  each  of  the  parties  agrees  that  such  Designated  Foreign
Borrower otherwise shall be a Borrower for all purposes of this Agreement; provided that no Loan Notice or Letter of Credit
Application may be submitted by or on behalf of such Designated Foreign Borrower until the date that is five (5) Business
Days after such effective date.

(c)        Obligations.  Except  as  specifically  provided  herein,  the  Obligations  of  each  of  the  Borrowers  (including,
without limitation, Obligations under Sections 2.07, 2.08 and 2.09) shall be joint and several in nature, regardless of which
Person  actually  receives  Credit  Extensions  hereunder  or  the  amount  of  such  Credit  Extensions  received  or  the  manner  in
which the Administrative Agent, the L/C Issuer or any Lender accounts for such Credit Extensions on its books and records;
provided,  however,  that  notwithstanding  anything  contained  to  the  contrary  herein  or  in  any  other  Loan  Document,  the
Designated Foreign Borrowers shall not be liable with respect to any Obligations of the Company.

(d)    Appointment. Each Restricted Subsidiary of the Company that is or becomes a Designated Foreign Borrower
hereby irrevocably appoints, designates and authorizes the Company to act on its behalf as its agent for all purposes of this
Agreement and the other Loan Documents and authorizes the Company to take such actions on its behalf and to exercise
such powers as are delegated to the Company by the terms hereof or thereof, together with such actions and powers as are
reasonably incidental thereto. Each Restricted Subsidiary of the Company that is or becomes a Designated Foreign Borrower
hereby further agrees that (i) the Company may execute such documents on behalf of such Designated Foreign Borrower as
the Company deems appropriate in its sole discretion and each Designated Foreign Borrower shall be obligated by all of the
terms of any such document executed on its behalf, (ii) any notice or communication delivered by the Administrative Agent
or the Lender to the Company shall be deemed delivered to each Designated Foreign Borrower and (iii) the Administrative
Agent  or  the  Lenders  may  accept,  and  be  permitted  to  rely  on,  any  document,  instrument  or  agreement  executed  by  the
Company on behalf of each of the Loan Parties.

(e)    Termination. The Company may from time to time, upon not less than three (3) Business Days’ prior written
notice from the Company to the Administrative Agent (or such shorter period as may be agreed by the Administrative Agent
in its sole discretion), terminate a Designated Foreign Borrower’s status as such; provided that (i) there are no outstanding
Loans payable by such Designated Foreign Borrower, Letters of Credit issued for the account of such Designated Foreign
Borrower  or  any  of  its  Subsidiaries,  or  other  amounts  due  and  payable  by  such  Designated  Foreign  Borrower  as  of  the
effective date of such termination, (ii) no Event of Default has occurred and is continuing or would result therefrom and (iii)
immediately after giving effect to such termination, the aggregate outstanding principal amount of all Priority Indebtedness
shall not exceed fifteen percent (15%) of Consolidated Net Worth (determined as of the last day of the most recent fiscal
quarter  for  which  financial  statements  shall  have  been  delivered  pursuant  to  Section  6.01(a)  or  6.01(b)  (or,  prior  to  the
delivery of any such financial statements, determined as of June 30, 2019)); provided further, that the Administrative Agent,
the applicable L/C Issuer and the Lenders shall cooperate with any Designated Foreign Borrower to amend or replace any
Letter of Credit in order to name the Company as the applicant or account party with respect to any Letter of Credit issued
for  the  account  of  such  Designated  Foreign  Borrower  or  any  of  its  Subsidiaries.  The Administrative Agent will promptly
notify the Lenders of any such termination of a Designated Foreign Borrower’s status.

2.17    Designated Lenders.

Each  of  the  Administrative  Agent,  each  L/C  Issuer,  each  Swingline  Lender  and  each  Lender  at  its  option  may  make  any
Credit  Extension  or  otherwise  perform  its  obligations  hereunder  through  any  Lending  Office  (each,  a  “Designated  Lender”);
provided  that  any  exercise  of  such  option  shall  not  affect  the  obligation  of  any  Borrower  to  repay  any  Credit  Extension  in
accordance with the terms of this Agreement. Any Designated Lender shall be considered a Lender; provided that designation of a
Designated Lender is for administrative convenience only and does not expand the scope of liabilities or obligations of any Lender
or Designated Lender beyond those of the Lender designating such Person as a Designated Lender as provided in this Agreement.

2.18    Increase in Revolving Commitments.

(a)    Increase in Revolving Facility.

(i)        Upon  notice  to  the  Administrative  Agent  (which  shall  promptly  notify  the  Revolving  Lenders),  the
Company  may  from  time  to  time  after  the  Closing  Date,  request  an  increase  in  the  Revolving  Facility  by  an
aggregate amount (for all such requests) not to exceed $500,000,000 (any such increase in the Revolving Facility, an
“Incremental Revolving Facility”); provided that (i) any such request for an Incremental Revolving Facility shall be
in  a  minimum  amount  of  $25,000,000,  and  in  increments  of  $5,000,000  in  excess  thereof,  or,  if  less,  the  entire
remaining  amount  available  for  such  Incremental  Revolving  Facility,  and  (ii)  in  no  event  shall  the  Aggregate
Revolving Commitments under

the Revolving Facility (after giving effect to all requested increases therein) exceed $1,000,000,000. Subject to the
terms and conditions hereof, the Company may seek commitments from existing Lenders or any other Person that is
an  Eligible  Assignee  who  shall  become  a  Revolving  Lender  in  connection  therewith.  At  the  time  of  sending  such
notice, the Company (in consultation with the Administrative Agent) shall specify the time period within which each
Revolving Lender is requested to respond (which shall in no event be less than ten (10) Business Days from the date
of delivery of such notice to the Revolving Lenders).

(ii)    Revolving Lender Elections to Increase. Each Revolving Lender shall notify the Administrative Agent
within  such  time  period  whether  or  not  it  agrees  to  increase  its  Revolving  Commitment  and,  if  so,  whether  by  an
amount  equal  to,  greater  than,  or  less  than  its  Applicable  Percentage  of  such  requested  increase.  Any  Revolving
Lender  not  responding  within  such  time  period  shall  be  deemed  to  have  declined  to  increase  its  Revolving
Commitment.

(iii)    Notification by Administrative Agent; Additional Revolving Lenders. The Administrative Agent shall
notify  the  Company  and  each  Revolving  Lender  of  the  Revolving  Lenders’  responses  to  each  request  made
hereunder. To achieve the full amount of a requested increase (to the extent the existing Revolving Lenders do not
agree  to  provide  the  entire  amount  of  the  requested  increase),  and  subject  to  the  approval  of  the  Administrative
Agent,  the  L/C  Issuers  and  the  Swingline  Lender,  the  Company  may  also  invite  additional  Eligible  Assignees  to
become  Revolving  Lenders  (together  with  any  existing  Revolving  Lender  participating  in  such  increase,  each,  an
“Increasing Revolving Lender”) pursuant to a joinder agreement in form and substance reasonably satisfactory to the
Administrative  Agent  and  its  counsel.  Nothing  contained  herein  shall  constitute,  or  otherwise  be  deemed  to  be,  a
commitment on the part of any Revolving Lender to participate in any increase in the Revolving Facility.

(iv)    Effective Date and Allocations. If the Revolving Facility is increased in accordance with this Section,
the  Administrative  Agent  and  the  Company  shall  determine  (x)  the  effective  date  of  any  such  increase  (the
“Revolving  Facility  Increase  Effective  Date”)  and  (y)  the  final  allocation  of  such  increase  among  the  Increasing
Revolving  Lenders  and  Schedule  1.01(b)  attached  hereto  shall  be  automatically  updated  to  reflect  the  same.  The
Administrative Agent shall promptly notify the Company and the Revolving Lenders of the final allocation of such
increase and the Revolving Facility Increase Effective Date.

(b)        Conditions  to  Effectiveness  of  Increase.  As  a  condition  precedent  to  each  such  increase  in  the  Revolving

Facility pursuant to this Section 2.18:

(i)        as  of  the  Revolving  Facility  Increase  Effective  Date,  before  and  after  giving  effect  to  such  increase,
(A) no Default or Event of Default shall then exist or would exist after giving effect thereto exists, (B) the Company
shall demonstrate to the reasonable satisfaction of the Administrative Agent that, after

giving effect to such increase on a Pro Forma Basis (as if the entire amount of the Incremental Revolving Facility has
been fully-funded), the Company is in Pro Forma Compliance, and (C) the representations and warranties contained
in Article V and each other Loan Documents shall be true and correct in all material respects (or in the case of a
representation or warranty that is already subject to a materiality condition, in all respects), except to the extent that
such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct
as of such earlier date, and except that for purposes of this Section 2.18, the representations and warranties contained
in clauses (a) and (b) of Section 5.05 shall be deemed to refer to the most recent statements furnished pursuant to
clauses (a) and (b), respectively, of Section 6.01.

(ii)    the Company shall have delivered to the Administrative Agent a certificate of each Loan Party dated as
of the Revolving Facility Increase Effective Date, signed by a Responsible Officer of such Loan Party (x) certifying
and attaching the resolutions adopted by such Loan Party approving or consenting to such increase, and (y) certifying
(and  attaching  calculations,  as  appropriate,  in  reasonable  detail  necessary  to  demonstrate)  that,  before  and  after
giving effect to such increase each, of the conditions set forth in clause (i) above are satisfied; and

(iii)        the  Company  shall  have  delivered,  or  cause  to  be  delivered,  customary  legal  opinions,  officers’
certificates, reaffirmation agreements and other documents consistent in all material respects with those delivered on
the Closing Date under Section 4.01 with respect to the Company, the other Borrowers and all applicable Subsidiary
Guarantors (other than changes to such legal opinions resulting from a change in Law, change in fact or change to
counsel’s  form  of  opinion  reasonably  satisfactory  to  the  Administrative  Agent)  as  reasonably  requested  by  the
Administrative Agent in connection with each such increase in the Revolving Facility.

The  applicable  Borrowers  shall  prepay  any  Revolving  Loans  outstanding  on  the  Revolving  Facility  Increase
Effective  Date  (and  pay  any  additional  amounts  required  pursuant  to  Section  3.05)  to  the  extent  necessary  to  keep  the
outstanding  Revolving  Loans  ratable  with  any  revised  Applicable  Revolving  Percentages  arising  from  any  nonratable
increase in the Revolving Commitments under this Section 2.18.

(c)    Terms of Increase. Any increase in the Revolving Facility shall be made on the same terms (including, without
limitation,  interest,  payment,  amortization  and  maturity  terms),  and  shall  be  subject  to  the  same  conditions  as  existing
Revolving  Commitments  (or,  if  more  than  one  Class  of  Revolving  Commitments  is  then  outstanding,  the  Revolving
Commitments  with  the  then  Latest  Maturity  Date)  except  customary  arrangement  or  commitment  fees  payable  to  the
Arrangers  or  one  or  more  Increasing  Revolving  Lenders  may  be  different  from  those  paid  with  respect  to  the  existing
Revolving Commitments of the existing Lenders on or prior to the Closing Date

or with respect to any other Increasing Revolving Lender in connection with any other increase in the Revolving Facility
pursuant to this Section 2.18.

(d)        Conflicting  Provisions.  This  Section  2.18  shall  supersede  any  provisions  in  Section  2.13  or  11.01  to  the

contrary.

2.19    Extension of Maturity Date.

(a)    Request for Extended Revolving Commitments. So long as no Event of Default has occurred and is continuing,
the Borrowers may at any time and from time to time, upon written request to and the consent of the Administrative Agent,
the  Swingline  Lender  and  the  L/C  Issuers,  request  (each,  a  “Revolving  Extension  Request”)  that  an  aggregate  principal
amount  of  not  less  than  $100,000,000  of  the  then  existing  Revolving  Commitments  of  any  Class  (each,  an  “Existing
Revolving  Tranche”)  be  amended  to,  among  other  things,  extend  the  applicable  Maturity  Date  with  respect  thereto  (the
“Existing Maturity Date”) to a date that is no earlier than the then Latest Maturity Date of any other Revolving Commitment
hereunder  (any  such  Revolving  Commitments  so  amended,  “Extended  Revolving  Commitments”);  provided  that  (i)  after
giving effect to any Extended Revolving Commitments under this Section 2.19, there shall be no more than three (3) Classes
of Revolving Commitments outstanding at any time and (ii) any such Extended Revolving Commitments shall be offered on
the  same  terms  to  each  Revolving  Lender  under  the  applicable  Existing  Revolving  Tranche  on  a  ratable  basis.  For  the
avoidance  of  doubt,  the  reference  to  “on  the  same  terms”  in  the  preceding  sentence  shall  mean  that  all  of  the  Revolving
Lenders holding such Existing Revolving Tranche are offered to be extended for the same amount of time, offered the same
type of Revolving Commitment and that the interest rate changes and fees payable with respect to such extension are the
same. Promptly after receipt of any Revolving Extension Request, the Administrative Agent shall provide a copy of such
request to each of the Revolving Lenders under the applicable Existing Revolving Tranche to be amended, which request
shall set forth the proposed terms (which shall be determined in consultation with the Administrative Agent) of the Extended
Revolving  Commitments  to  be  established.  Each  Revolving  Extension  Request  shall  specify  (A)  the  applicable  Class  of
Revolving Commitments and Revolving Loans hereunder to be extended, (B) the date to which the applicable Maturity Date
is sought to be extended, and (C) the changes, if any, to the Applicable Rate to be applied in determining the interest payable
on the Revolving Loans of, and fees payable hereunder to, Extending Revolving Lenders in respect of that portion of their
Revolving Commitments and Revolving Loans extended to such new Maturity Date; provided, however, that such Extended
Revolving Commitments shall, except as to interest rates, fees and any other pricing terms and final maturity, have the same
terms (including borrowing terms and payment terms (other than payment on the applicable Maturity Date)) as the existing
Class  of  Revolving  Commitments  from  which  they  are  extended.  At  the  time  of  sending  such  notice,  the  Company  (in
consultation with the Administrative Agent) shall specify the time period within which each applicable Revolving Lender is
requested to respond to such request (which shall in no event be less than fifteen (15) calendar days (or such shorter period
as

may be agreed by the Administrative Agent) from the date of delivery of such notice to such Revolving Lenders) and shall
agree  to  such  procedures,  if  any,  as  may  be  established  by,  or  reasonably  acceptable  to,  the  Administrative  Agent  to
accomplish the purposes of this Section 2.19.

(b)        Election  to  Extend.  Any  Revolving  Lender  wishing  to  have  all  (but  not  less  than  all)  of  its  Revolving
Commitments under the Existing Revolving Tranche amended into Extended Revolving Commitments (each, including any
Additional  Commitment  Lenders  (as  defined  below),  an  “Extending  Revolving  Lender”)  specified  in  the  Revolving
Extension  Request  shall  notify  the  Administrative  Agent  on  or  prior  to  the  response  date  specified  in  such  Revolving
Extension  Request  of  the  Revolving  Commitments  it  has  elected  to  be  amended.  No  Revolving  Lender  shall  have  any
obligation  to  agree  to  provide  any  Extended  Revolving  Commitment  pursuant  to  any  Revolving  Extension  Request.  Any
Revolving  Lender  that  determines  not  to  extend  its  Revolving  Commitments  under  the  Existing  Revolving  Tranche,  and
notifies the Administrative Agent as to the same, or does not responding on or prior to such response date shall be deemed to
have declined such Revolving Extension Request and, in each case, shall constitute a “Non-Consenting Lender” hereunder.
The Administrative Agent shall notify the Company and each Revolving Lender under the applicable Existing Revolving
Tranche  of  responses  to  such  Revolving  Extension  Request.  In  the  event  that  the  aggregate  principal  amount  of  existing
Revolving Commitments that the Extending Revolving Lenders have elected to amend pursuant to the relevant Revolving
Extension  Request  exceeds  the  amount  of  Extended  Revolving  Commitments  requested  by  the  Borrowers,  the  principal
amount of Extended Revolving Commitments requested by the Borrowers shall be allocated to each Extending Revolving
Lender  in  such  manner  and  in  such  amounts  as  may  be  agreed  by  Administrative  Agent  and  the  Company,  in  their  sole
discretion.

(c)    Additional Commitment Lenders. The Company shall have the right to replace each Non-Consenting Lender
with,  and  add  as  “Revolving  Lenders”  under  this  Agreement  in  place  thereof,  one  or  more  Eligible  Assignees  (each,  an
“Additional  Commitment  Lender”)  as  provided  in  Section  11.13;  provided  that  each  of  such  Additional  Commitment
Lenders shall enter into an Assignment and Assumption in connection with any such Revolving Extension Request pursuant
to  which  such  Additional  Commitment  Lender  shall  undertake  a  Revolving  Commitment  (and,  if  any  such  Additional
Commitment  Lender  is  already  a  Lender,  its  Revolving  Commitment  shall  be  in  addition  to  any  other  Revolving
Commitment of such Lender hereunder on such date) from one or more Non-Consenting Lenders.

(d)        Revolving  Extension  Amendment.  Extended  Revolving  Commitments  shall  be  established  pursuant  to  an
amendment  (each,  a  “Revolving  Extension  Amendment”)  to  this  Agreement  among  the  Borrowers,  the  Administrative
Agent  and  each  Extending  Revolving  Lender,  if  any,  providing  an  Extended  Revolving  Commitment,  which  shall  be
consistent with the provisions set forth in Sections 2.19(a), (b) and (d) (but which shall not require the consent of any other
Lender). The

effectiveness of any Revolving Extension Amendment shall be subject to the satisfaction on the date thereof of each of the
conditions set forth in Sections 4.02(a) and 4.02(b) (but solely limited to an Event of Default) (with all references in such
Sections  to  a  Credit  Extension  being  deemed  to  be  references  to  such  Revolving  Extension  Request)  and  receipt  of  a
certificate to that effect and, any other condition as may be agreed among the Borrowers, the Administrative Agent and the
Extending  Revolving  Lenders.  In  addition,  the  Company  shall  have  delivered,  or  cause  to  be  delivered,  customary  legal
opinions, officers’ certificates, reaffirmation agreements and other documents consistent in all material respects with those
delivered  on  the  Closing  Date  under  Section  4.01  with  respect  to  the  Company,  the  other  Borrowers  and  all  applicable
Subsidiary Guarantors (other than changes to such legal opinions resulting from a change in Law, change in fact or change
to  counsel’s  form  of  opinion  reasonably  satisfactory  to  the  Administrative  Agent)  as  reasonably  requested  by  the
Administrative Agent in connection with each such extension. The Administrative Agent shall promptly notify each Lender
as to the effectiveness of each Revolving Extension Amendment and the matters specified therein. Each of the parties hereto
hereby  agrees  that  this  Agreement  and  the  other  Loan  Documents  may  be  amended  pursuant  to  a  Revolving  Extension
Amendment,  without  the  consent  of  any  other  Lender,  to  the  extent  (but  only  to  the  extent)  necessary  to  (i)  reflect  the
existence  and  terms  of  the  Extended  Revolving  Commitments  incurred  pursuant  thereto,  and  (ii)  effect  such  other
amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion
of  the  Administrative  Agent  and  the  Borrowers,  to  effect  the  provisions  of  this  Section  2.19,  in  each  case,  in  a  manner
consistent  with  the  terms  of  this  Section  2.19,  and  the  Required  Lenders  hereby  expressly  authorize  the  Administrative
Agent to enter into any such Revolving Extension Amendment.

(e)        Terms  of  Extended  Revolving  Commitments.  Except  as  expressly  provided  herein,  all  Extended  Revolving
Commitments effected pursuant to any Revolving Extension Request and Revolving Extension Amendment shall be subject
to the same terms, and shall be subject to the same conditions as the Existing Revolving Tranche. After giving effect to any
Extended  Revolving  Commitment,  all  borrowings  under  the  Revolving  Commitments  (including  any  such  Extended
Revolving  Commitments)  and  repayments  thereunder  shall  be  made  on  a  pro  rata  basis  (except  for  (x)  any  payments  of
interest  and  fees  at  different  rates  on  any  Revolving  Extension  Series  (and  related  Loans  thereunder),  (y)  repayments
required upon the applicable Maturity Date of other Revolving Commitments and (z) except as otherwise expressly set forth
herein). If a Revolving Extension Amendment has become effective hereunder, not later than the third Business Day prior to
the Existing Maturity Date, the Borrowers shall make prepayments of Revolving Loans and shall Cash Collateralize Letters
of Credit, such that, after giving effect to such prepayments and such provision of Cash Collateral, the aggregate Revolving
Exposure  as  of  such  date  will  not  exceed  the  aggregate  applicable  Extended  Revolving  Commitments  of  the  Extended
Revolving  Lenders  (and  the  Borrowers  shall  not  be  permitted  thereafter  to  request  any  Revolving  Loan  or  any  issuance,
amendment, renewal or extension of a Letter of Credit if, after giving effect

thereto, the applicable Revolving Exposure would exceed the aggregate amount of the Extended Revolving Commitments
then in effect).

(f)        Revolving  Extension  Series.  Any  Extended  Revolving  Commitments  effected  pursuant  to  a  Revolving
Extension Request shall be designated a series (each, a “Revolving Extension Series”) of Extended Revolving Commitments
for  all  purposes  of  this  Agreement;  provided  that  any  Extended  Revolving  Commitments  effected  from  an  Existing
Revolving  Tranche  may,  to  the  extent  provided  in  the  applicable  Revolving  Extension  Amendment,  be  designated  as  an
increase  in  any  previously  established  Revolving  Extension  Series  with  respect  to  such  Existing  Revolving  Tranche.  In
connection  with  the  foregoing,  Schedule  1.01(b)  attached  hereto  shall  be  updated  to  reflect  each  applicable  Revolving
Extension Series, in a manner reasonably satisfactory to the Administrative Agent.

(g)        Changes  to  Applicable  Rate.  In  connection  with  any  extension  of  the  Maturity  Date  made  pursuant  to  this
Section  2.19,  the  Applicable  Rate  applicable  to  Loans  made  and  to  be  made  by  Extending  Revolving  Lenders  may  be
modified without any consent of any other Lender, provided that no such modification shall apply to the Loans of the other
Lenders unless the Company and the Administrative Agent (without any requirement of consultation with or approval by
any  other  Lender)  determine  that  such  change  should  apply  to  the  Loans  of  the  other  Lenders  and  either  (i)  such  other
Lender has consented to such change (notwithstanding itssuch Lender is not consenting to the applicable  extension  of  the
Maturity  Date)  or  (ii)  such  change  represents  an  increase  in  the  Applicable  Rate  applicable  to  the  Loans  of  the  other
Lenders.

(h)        Conflicting  Provisions.  This  Section  2.19  shall  supersede  any  provisions  in  Section  2.13  or  11.01  to  the

contrary.

3.01    Taxes.

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

(a)    Payments Free of Taxes; Obligation to Withhold; Payments on Account of Taxes.

(i)    Any and all payments by or on account of any obligation of any Loan Party under any Loan Document
shall  be  made  without  deduction  or  withholding  for  any  Taxes,  except  as  required  by  applicable  Laws.  If  any
applicable  Laws  (as  determined  in  the  good  faith  discretion  of  the  Administrative  Agent)  require  the  deduction  or
withholding of any Tax from any such payment by the Administrative Agent or a Loan Party, then the Administrative
Agent or such Loan Party shall be entitled to make such deduction or withholding, upon the basis of the information
and documentation to be delivered pursuant to this Section 3.01.

(ii)    If any Loan Party or the Administrative Agent shall be required by the Code to withhold or deduct any
Taxes,  including  both  United  States  federal  backup  withholding  and  withholding  taxes,  from  any  payment,  then
(A) the Administrative Agent shall withhold or make such deductions as are determined by the Administrative Agent
to be required based upon the information and documentation it has received pursuant to this Section 3.01, (B) the
Administrative Agent shall timely pay the full amount withheld or deducted to the relevant Governmental Authority
in  accordance  with  the  Code  and  (C)  to  the  extent  that  the  withholding  or  deduction  is  made  on  account  of
Indemnified Taxes, the sum payable by the applicable Loan Party shall be increased as necessary so that after any
required withholding or the making of all required deductions (including withholdings and deductions applicable to
additional  sums  payable  under  this  Section  3.01)  the  applicable  Recipient  receives  an  amount  equal  to  the  sum  it
would have received had no such withholding or deduction been made.

(iii)    If any Loan Party or the Administrative Agent shall be required by any applicable Laws other than the
Code to withhold or deduct any Taxes from any payment, then (A) such Loan Party or the Administrative Agent, as
required by such Laws, shall withhold or make such deductions as are determined by it to be required based upon the
information  and  documentation  it  has  received  pursuant  to  this  Section  3.01,  (B)  such  Loan  Party  or  the
Administrative Agent, to the extent required by such Laws, shall timely pay the full amount withheld or deducted to
the  relevant  Governmental  Authority  in  accordance  with  such  Laws  and  (C)  to  the  extent  that  the  withholding  or
deduction is made on account of Indemnified Taxes, the sum payable by the applicable Loan Party shall be increased
as necessary so that after any required withholding or the making of all required deductions (including withholdings
and deductions applicable to additional sums payable under this Section 3.01) the applicable Recipient receives an
amount equal to the sum it would have received had no such withholding or deduction been made.

(iv)    A Loan Party shall promptly upon becoming aware that it must make a deduction or withholding for
any  Taxes  from  a  payment  under  any  Loan  Document  (or  that  there  is  a  change  in  the  rate  or  the  basis  of  such
deduction or withholding) notify the Administrative Agent (who shall notify any relevant Lenders) accordingly.

(b)    Payment of Other Taxes by the Loan Parties. Without limiting the provisions of subsection (a) above, the Loan
Parties shall timely pay to the relevant Governmental Authority in accordance with applicable Law, or at the option of the
Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(c)    Tax Indemnifications.

(i)        Each  of  the  Loan  Parties  shall,  and  does  hereby,  jointly  and  severally  indemnify  each  Recipient,  and
shall  make  payment  in  respect  thereof  within  ten  (10)  days  after  demand  therefor,  for  the  full  amount  of  any
Indemnified  Taxes  (including  Indemnified  Taxes  imposed  or  asserted  on  or  attributable  to  amounts  payable  under
this Section 3.01) payable or paid by such Recipient or required to be withheld or deducted from a payment to such
Recipient, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or
not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the applicable Loan Party by a Lender or an L/C
Issuer (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a
Lender  or  an  L/C  Issuer,  shall  be  conclusive  absent  manifest  error.  Each  of  the  Loan  Parties  shall  also,  and  does
hereby, jointly and severally indemnify the Administrative Agent, and shall make payment in respect thereof within
ten  (10)  days  after  demand  therefor,  for  any  amount  which  a  Lender  or  an  L/C  Issuer  for  any  reason  fails  to  pay
indefeasibly to the Administrative Agent as required pursuant to Section 3.01(c)(ii) below.

(ii)    Each Lender and each L/C Issuer shall, and does hereby, severally indemnify and shall make payment
in respect thereof within ten (10) days after demand therefor, (A) the Administrative Agent against any Indemnified
Taxes  attributable  to  such  Lender  or  such  L/C  Issuer  (but  only  to  the  extent  that  any  Loan  Party  has  not  already
indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Loan
Parties to do so), (B) the Administrative Agent and the Loan Parties, as applicable, against any Taxes attributable to
such Lender’s failure to comply with the provisions of Section 11.06(d) relating to the maintenance of a Participant
Register  and  (C)  the  Administrative  Agent  and  the  Loan  Parties,  as  applicable,  against  any  Excluded  Taxes
attributable to such Lender or such L/C Issuer, in each case, that are payable or paid by the Administrative Agent or a
Loan Party in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect
thereto,  whether  or  not  such  Taxes  were  correctly  or  legally  imposed  or  asserted  by  the  relevant  Governmental
Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative
Agent  shall  be  conclusive  absent  manifest  error.  Each  Lender  and  each  L/C  Issuer  hereby  authorizes  the
Administrative Agent to set off and apply any and all amounts at any time owing to such Lender or such L/C Issuer,
as the case may be, under this Agreement or any other Loan Document against any amount due to the Administrative
Agent under this clause (ii).

(d)    Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental

Authority, as provided in this Section 3.01, the

applicable Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such
Governmental Authority evidencing such payment, a copy of any return reporting such payment or other evidence of such
payment reasonably satisfactory to the Administrative Agent.

(e)    Status of Lenders; Tax Documentation.

(i)        Any  Lender  that  is  entitled  to  an  exemption  from  or  reduction  of  withholding  Tax  with  respect  to
payments made under any Loan Document shall deliver to the applicable Borrower and the Administrative Agent, at
the  time  or  times  reasonably  requested  by  the  applicable  Borrower  or  the  Administrative  Agent,  such  properly
completed  and  executed  documentation  reasonably  requested  by  the  applicable  Borrower  or  the  Administrative
Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition,
any Lender, if reasonably requested by the applicable Borrower or the Administrative Agent, shall deliver such other
documentation  prescribed  by  applicable  Law  or  reasonably  requested  by  the  applicable  Borrower  or  the
Administrative Agent as will enable the applicable Borrower or the Administrative Agent to determine whether or
not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything
to  the  contrary  in  the  preceding  two  sentences,  the  completion,  execution  and  submission  of  such  documentation
(other than such documentation set forth in Section 3.01(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if
in  the  Lender’s  reasonable  judgment  such  completion,  execution  or  submission  would  subject  such  Lender  to  any
material  unreimbursed  cost  or  expense  or  would  materially  prejudice  the  legal  or  commercial  position  of  such
Lender.

(ii)       Without  limiting  the  generality  of  the  foregoing,  in  the  event  that  the  applicable  Borrower  is  a  U.S.

Person (including the Company),

(A)    any Lender that is a U.S. Person shall deliver to the Company and the Administrative Agent on
or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time
thereafter upon the reasonable request of the Company or the Administrative Agent), executed copies of IRS
Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B)    any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Company and
the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the
date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter
upon  the  reasonable  request  of  the  Company  or  the  Administrative  Agent),  whichever  of  the  following  is
applicable:

(1)    in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the
United States is a party (x) with respect to payments of interest under any Loan Document, executed
copies  of  IRS  Form  W-8BEN-E  (or  W-8BEN,  as  applicable)  establishing  an  exemption  from,  or
reduction  of,  U.S.  federal  withholding  Tax  pursuant  to  the  “interest”  article  of  such  tax  treaty  and
(y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN-E
(or W-8BEN, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding
Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2)    executed originals of IRS Form W-8ECI;

(3)        in  the  case  of  a  Foreign  Lender  claiming  the  benefits  of  the  exemption  for  portfolio
interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit I-1 to
the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the
Code, a “10 percent shareholder” of the Company within the meaning of Section 881(c)(3)(B) of the
Code,  or  a  “controlled  foreign  corporation”  described  in  Section  881(c)(3)(C)  of  the  Code  (a  “U.S.
Tax  Compliance  Certificate”)  and  (y)  executed  copies  of  IRS  Form  W-8BEN-E  (or  W-8BEN,  as
applicable); or

(4)    to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form
W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN-E (or W-8BEN, as applicable), a
U.S. Tax Compliance Certificate substantially in the form of Exhibit I-2 or Exhibit I-3, IRS Form W-
9, and/or other certification documents from each beneficial owner, as applicable; provided that if the
Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are
claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance
Certificate substantially in the form of Exhibit I-4 on behalf of each such direct and indirect partner;

(C)    any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Company and
the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the
date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter
upon the reasonable request of the Company or the Administrative Agent), executed copies (or originals, as
required) of any other form prescribed by applicable Law as a

basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together
with such supplementary documentation as may be prescribed by applicable Law to permit the Company or
the Administrative Agent to determine the withholding or deduction required to be made; and

(D)        if  a  payment  made  to  a  Lender  under  any  Loan  Document  would  be  subject  to  U.S.  federal
withholding  Tax  imposed  by  FATCA  if  such  Lender  were  to  fail  to  comply  with  the  applicable  reporting
requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable),
such Lender shall deliver to the Company and the Administrative Agent at the time or times prescribed by
law  and  at  such  time  or  times  reasonably  requested  by  the  Company  or  the  Administrative  Agent  such
documentation  prescribed  by  applicable  Law  (including  as  prescribed  by  Section  1471(b)(3)(C)(i)  of  the
Code) and such additional documentation reasonably requested by the Company or the Administrative Agent
as may be necessary for the Company and the Administrative Agent to comply with their obligations under
FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to
determine  the  amount  to  deduct  and  withhold  from  such  payment.  Solely  for  purposes  of  this  clause  (D),
“FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(iii)    Each Lender agrees that if any form or certification it previously delivered pursuant to this Section 3.01
expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify
the applicable Borrower and the Administrative Agent in writing of its legal inability to do so.

(f)    An Irish Treaty Lender and the applicable Borrower shall co-operate in completing any procedural formalities
necessary  for  the  applicable  Borrower  to  obtain  authorization  to  make  a  payment  to  that  Irish  Treaty  Lender  without  any
deduction or withholding of any tax imposed by Ireland.

(g)        In  respect  of  Loans  advanced  to  a  Loan  Party  that  is  within  the  charge  to  UK  TaxesUnited  Kingdom

corporation tax:

(i)    Subject to Section 3.01(g)(ii), a UK Treaty Lender and each Loan Party which makes a payment under a
Loan Document to which that UK Treaty Lender is entitled shall cooperate in completing any procedural formalities
necessary for such Loan Party to obtain authorization to make that payment without a UK Tax Deduction, including
making and filing of an appropriate application for relief under an applicable Treaty.

(ii)    A UK Treaty Lender that holds a passport under the HMRC Double Taxation Treaty Passport Scheme
(“UK  DTTP  Scheme”)  and  which  wishes  the  UK  DTTP  Scheme  to  apply  to  this  Agreement,  shall  confirm  its
scheme reference number and jurisdiction of tax residence in: (A) where the UK Treaty Lender is a Lender on the
date of this Agreement, Schedule 1.01(d) to this Agreement; or (B) where the UK Treaty Lender becomes a Lender
after  the  date  of  this  Agreement,  the  relevant  Assignment  and  Assumption,  and,  having  done  so,  that  UK  Treaty
Lender shall be under no obligation pursuant to Section 3.01(g)(i) to cooperate with the relevant Loan Party but, for
avoidance  of  doubt,  such  UK  Treaty  Lender  shall  have  an  obligation  to  cooperate  further  with  the  relevant  Loan
Party in accordance with Section 3.01(g)(iii).

(iii)    If a UK Treaty Lender has confirmed its scheme reference number and its jurisdiction of tax residence

in accordance with Section 3.01(g)(ii) and:

(A)    a Loan Party making a payment to that UK Treaty Lender has not made a UK DTTP Filing in

respect of that UK Treaty Lender; or

(B)        a  Loan  Party  making  a  payment  to  that  UK  Treaty  Lender  has  made  a  UK  DTTP  Filing  in
respect of that Lender but either (a1) that UK DTTP Filing has been rejected by HMRC or (b2) HMRC has
not given the Loan Party authority to make payments to that UK Treaty Lender without a UK Tax Deduction
within forty (40) Business Days of the date of the UK DTTP Filing, and in each case, the relevant Loan Party
has notified that UK Treaty Lender in writing, that UK Treaty Lender and the Loan Party shall cooperate in
completing  any  additional  procedural  formalities  necessary  for  that  Loan  Party  to  obtain  authorization  to
make that payment without a UK Tax Deduction.

(iv)        If  a  Lender  has  not  confirmed  its  scheme  reference  number  and  jurisdiction  of  tax  residence  in
accordance with Section 3.01(g)(ii), no Loan Party shall make a UK DTTP Filing or file any other form relating to
the UK DTTP Scheme in respect of that Lender's Revolving Commitment or participation in any Loan unless the
Lender otherwise agrees.

(v)    A Loan Party shall, promptly after making a UK DTTP Filing, deliver a copy of the UK DTTP Filing to

the Administrative Agent for delivery to the relevant Lender.

(vi)    A Lender that is a Lender on the date of this Agreement that is a UK Qualifying Lender solely by virtue
of  sub-paragraph  (b)  of  the  definition  of  UK  Qualifying  Lender  gives  a  UK  Tax  Confirmation  to  Company  by
entering into the Agreement. A Lender that is a UK Qualifying Lender solely by virtue of sub-paragraph (b) of the
definition  of  UK  Qualifying  Lender  shall  promptly  notify  Company  and  the  Administrative  Agent  if  there  is  any
change in the position from that set out in the UK Tax Confirmation.

(vii)        Each  Lender  which  is  not  a  Lender  on  the  date  of  this  Agreement  shall  indicate  in  the  relevant
Assignment  and  Assumption,  for  the  benefit  of  the  Administrative  Agent,  but  without  liability  to  any  Loan  Party,
whether it is:

(A)    not a UK Qualifying Lender;

(B)    a UK Qualifying Lender (that is not a UK Treaty Lender); or

(C)    a UK Treaty Lender.

If a Lender fails to indicate its status in accordance with this Section 3.01(g)(vii) then such Lender shall be
treated  for  the  purposes  of  this  Agreement  (including  by  each  Loan  Party)  as  if  it  is  not  a  UK  Qualifying
Lender until such time as it notifies the Administrative Agent (and the Administrative Agent, upon receipt of
such  notification,  shall  inform  the  Company).  For  the  avoidance  of  doubt,  an  Assignment  and  Assumption
shall not be invalidated by any failure of a Lender to comply with this Section 3.01(g)(vii).

(h)    Each Lender which is not a Lender on the date of this Agreement shall indicate in the relevant Assignment and

Assumption, for the benefit of the Administrative Agent, but without liability to any Loan Party, whether it is:

(i)    not an Irish Qualifying Lender;

(ii)    an Irish Qualifying Lender (that is not an Irish Treaty Lender); or

(iii)    an Irish Treaty Lender.

If a Lender fails to indicate its status in accordance with this Section 3.01(h) then such Lender shall be treated for the
purposes of this Agreement (including by each Loan Party) as if it is not an Irish Qualifying Lender until such time
as it notifies the Administrative Agent (and the Administrative Agent, upon receipt of such notification, shall inform
the Company). For the avoidance of doubt, an Assignment and Assumption shall not be invalidated by any failure of
a Lender to comply with this Section 3.01(h).

(i)    Treatment of Certain Refunds. Unless required by applicable Laws, at no time shall the Administrative Agent
have any obligation to file for or otherwise pursue on behalf of a Lender or an L/C Issuer, or have any obligation to pay to
any Lender or any L/C Issuer, any refund of Taxes withheld or deducted from funds paid for the account of such Lender or
such L/C Issuer, as the case may be. If any Recipient determines, in its sole discretion exercised in good faith, that it has
received a refund of any Taxes as to which it has been indemnified by any Loan Party or with respect to which any Loan
Party has paid additional amounts pursuant to this Section 3.01, it shall pay to such Loan Party

an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by such
Loan Party under this Section 3.01 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses
(including Taxes) incurred by such Recipient, as the case may be, and without interest (other than any interest paid by the
relevant  Governmental  Authority  with  respect  to  such  refund),  provided  that  each  Loan  Party,  upon  the  request  of  the
Recipient, agrees to repay the amount paid over to such Loan Party (plus any penalties, interest or other charges imposed by
the relevant Governmental Authority) to the Recipient in the event the Recipient is required to repay such refund to such
Governmental  Authority.  Notwithstanding  anything  to  the  contrary  in  this  subsection,  in  no  event  will  the  applicable
Recipient be required to pay any amount to such Loan Party pursuant to this subsection the payment of which would place
the  Recipient  in  a  less  favorable  net  after-Tax  position  than  such  Recipient  would  have  been  in  if  the  Tax  subject  to
indemnification  and  giving  rise  to  such  refund  had  not  been  deducted,  withheld  or  otherwise  imposed  and  the
indemnification payments or additional amounts with respect to such Tax had never been paid. This subsection shall not be
construed  to  require  any  Recipient  to  make  available  its  tax  returns  (or  any  other  information  relating  to  its  taxes  that  it
deems confidential) to any Loan Party or any other Person.

(j)    Survival. Each party’s obligations under this Section 3.01 shall survive the resignation or replacement of the
Administrative Agent or any assignment of rights by, or the replacement of, a Lender or an L/C Issuer, the termination of the
Revolving Commitments and the repayment, satisfaction or discharge of all other Obligations.

3.02    Illegality.

(a)    If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted
that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund or charge interest with respect
to any Credit Extension, or to determine or charge interest rates based upon the Eurocurrency Rate, or any Governmental
Authority  has  imposed  material  restrictions  on  the  authority  of  such  Lender  to  purchase  or  sell,  or  to  take  deposits  of,
Dollars  or  any  Alternative  Currency  in  the  applicable  interbank  market,  then,  upon  notice  thereof  by  such  Lender  to  the
Company  (through  the  Administrative  Agent),  (i)  any  obligation  of  such  Lender  to  make  or  continue  Eurocurrency  Rate
Loans  in  the  affected  currency  or  currencies  or,  in  the  case  of  Eurocurrency  Rate  Loans  in  Dollars,  to  convert  Base  Rate
Loans to Eurocurrency Rate Loans, shall be suspended, and (ii) if such notice asserts the illegality of such Lender making or
maintaining Base Rate Loans the interest rate on which is determined by reference to the Eurocurrency Rate component of
the  Base  Rate,  the  interest  rate  on  which  Base  Rate  Loans  of  such  Lender  shall,  if  necessary  to  avoid  such  illegality,  be
determined by the Administrative Agent without reference to the Eurocurrency Rate component of the Base Rate, in each
case  until  such  Lender  notifies  the  Administrative  Agent  and  the  Company  that  the  circumstances  giving  rise  to  such
determination no longer exist. Upon receipt of such notice, (A) the Borrowers shall, upon demand from such Lender (with a
copy to the Administrative Agent), prepay or, if applicable and such

Loans are denominated in Dollars, convert all Eurocurrency Rate Loans of such Lender to Base Rate Loans (the interest rate
on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative
Agent without reference to the Eurocurrency Rate component of the Base Rate), either on the last day of the Interest Period
therefor, if such Lender may lawfully continue to maintain such Eurocurrency Rate Loans to such day, or immediately, if
such  Lender  may  not  lawfully  continue  to  maintain  such  Eurocurrency  Rate  Loans  and  (B)  if  such  notice  asserts  the
illegality of such Lender determining or charging interest rates based upon the Eurocurrency Rate, the Administrative Agent
shall  during  the  period  of  such  suspension  compute  the  Base  Rate  applicable  to  such  Lender  without  reference  to  the
Eurocurrency  Rate  component  thereof  until  the  Administrative  Agent  is  advised  in  writing  by  such  Lender  that  it  is  no
longer  illegal  for  such  Lender  to  determine  or  charge  interest  rates  based  upon  the  Eurocurrency  Rate.  Upon  any  such
prepayment or conversion, the Borrowers shall also pay accrued interest on the amount so prepaid or converted, together
with any additional amounts required pursuant to Section 3.05.

(b)        If,  in  any  applicable  jurisdiction,  the  Administrative  Agent,  the  applicable  L/C  Issuer  or  any  Lender  or  any
Designated Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is
unlawful,  for  the  Administrative  Agent,  the  applicable  L/C  Issuer  or  any  Lender  or  its  applicable  Designated  Lender  to
(i) perform any of its obligations hereunder or under any other Loan Document, (ii) to fund, hold a commitment or maintain
its participation in any Loan or Letter of Credit or (iii) issue, make, maintain, fund or charge interest or fees with respect to
any  Credit  Extension,  such  Person  shall  promptly  notify  the  Administrative  Agent,  then,  upon  the  Administrative  Agent
notifying  the  Company,  and  until  such  notice  by  such  Person  is  revoked,  any  obligation  of  such  Person  to  issue,  make,
maintain,  fund  or  charge  interest  or  fees  with  respect  to  any  such  Credit  Extension  shall  be  suspended,  and  to  the  extent
required  by  applicable  Law,  cancelled.  Upon  receipt  of  such  notice,  the  Loan  Parties  shall,  (A)  repay  that  Person’s
participation  in  the  Loans  or  other  applicable  Obligations  on  the  last  day  of  the  Interest  Period  for  each  Loan  or  other
Obligation  occurring  after  the  Administrative  Agent  has  notified  the  Company  or,  if  earlier,  the  date  specified  by  such
Person in the notice delivered to the Administrative Agent (being no earlier than the last day of any applicable grace period
permitted by applicable Law), (B) to the extent applicable to the applicable L/C Issuer, Cash Collateralize that portion of
applicable L/C Obligations comprised of the aggregate undrawn amount of Letters of Credit to the extent not otherwise Cash
Collateralized and (C) take all reasonable actions requested by such Person to mitigate or avoid such illegality.

3.03    Inability to Determine Rates.

(a)        If  in  connection  with  any  request  for  a  Eurocurrency  Rate  Loan  or  a  conversion  to  or  continuation  thereof,
(i)  the  Administrative  Agent  determines  that  (A)  deposits  (whether  in  Dollars  or  an  Alternative  Currency)  are  not  being
offered to banks in the applicable offshore interbank market for such currency for the applicable amount and Interest Period
of such Eurocurrency Rate Loan, (B) (1) adequate and

reasonable  means  do  not  exist  for  determining  the  Eurocurrency  Rate  for  any  requested  Interest  Period  with  respect  to  a
proposed Eurocurrency Rate Loan (whether denominated in Dollars or an Alternative Currency) or in connection with an
existing  or  proposed  Base  Rate  Loan  and  (2)  the  circumstances  described  in  Section  3.03(c)(i)  do  not  apply  or  (C)  a
fundamental change has occurred in the foreign exchange or interbank markets with respect to such Alternative Currency
(including,  without  limitation,  changes  in  national  or  international  financial,  political  or  economic  conditions  or  currency
exchange  rates  or  exchange  controls)  (in  each  case  with  respect  to  this  clause  (i),  “Impacted  Loans”)  or  (ii)  the
Administrative Agent or the Required Lenders determine that for any reason Eurocurrency Rate for any requested Interest
Period with respect to a proposed Eurocurrency Rate Loan does not adequately and fairly reflect the cost to such Lenders of
funding  such  Loan,  the  Administrative  Agent  will  promptly  so  notify  the  Company  and  each  Lender.  Thereafter,  (x)  the
obligation  of  the  Lenders  to  make  or  maintain  Eurocurrency  Rate  Loans  in  the  affected  currency  or  currencies  shall  be
suspended (to the extent of the affected Eurocurrency Rate Loans or Interest Periods), and (y) in the event of a determination
described in the preceding sentence with respect to the Eurocurrency Rate component of the Base Rate, the utilization of the
Eurocurrency Rate component in determining the Base Rate shall be suspended, in each case until the Administrative Agent
(or,  in  the  case  of  a  determination  by  the  Required  Lenders  described  in  clause  (ii)  of  this  Section  3.03(a),  until  the
Administrative  Agent  upon  instruction  of  the  Required  Lenders)  revokes  such  notice.  Upon  receipt  of  such  notice,  the
Company may revoke any pending request for a Borrowing of, conversion to or continuation of Eurocurrency Rate Loans in
the affected currency or currencies (to the extent of the affected Eurocurrency Rate Loans or Interest Periods) or, failing that,
will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans in Dollars in the amount
specified therein.

(b)    Notwithstanding the foregoing, if the Administrative Agent has made the determination described in clause (a)
(i) of this Section 3.03, the Administrative Agent in consultation with the Company, may establish an alternative interest rate
for the Impacted Loans, in which case, such alternative rate of interest shall apply with respect to the Impacted Loans until
(i)  the  Administrative  Agent  revokes  the  notice  delivered  with  respect  to  the  Impacted  Loans  under  clause  (a)(i)  of  this
Section 3.03, (ii) the Administrative Agent or the Required Lenders notify the Administrative Agent and the Company that
such alternative interest rate does not adequately and fairly reflect the cost to such Lenders of funding the Impacted Loans or
(iii) any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is
unlawful, for such Lender or its applicable Lending Office to make, maintain or fund Loans whose interest is determined by
reference  to  such  alternative  rate  of  interest  or  to  determine  or  charge  interest  rates  based  upon  such  rate  or  any
Governmental Authority has imposed material restrictions on the authority of such Lender to do any of the foregoing and
provides the Administrative Agent and the Company written notice thereof.

(c)    Notwithstanding anything to the contrary in this Agreement or any other Loan Documents, but without limiting
Sections  3.01(a)  and  (b)  above,  if  the  Administrative  Agent  determines  (which  determination  shall  be  conclusive  and
binding upon all parties hereto absent manifest error), or the Company or Required Lenders notify the Administrative Agent
(with, in the case of the Required Lenders, a copy to the Company) that the Company or Required Lenders (as applicable)
have  determined  (which  determination  likewise  shall  be  conclusive  and  binding  upon  all  parties  hereto  absent  manifest
error), that:

(i)    adequate and reasonable means do not exist for ascertaining LIBOR for any requested Interest Period,
including, without limitation, because the LIBOR Screen Rate is not available or published on a current basis and
such circumstances are unlikely to be temporary; or

(ii)    the administrator of the LIBOR Screen Rate or a Governmental Authority having or purporting to have
jurisdiction  over  the  Administrative  Agent  has  made  a  public  statement  identifying  a  specific  date  after  which
LIBOR  or  the  LIBOR  Screen  Rate  shall  no  longer  be  made  available,  or  used  for  determining  the  interest  rate  of
loans in the applicable currency; provided that, at the time of such statement, there is no successor administrator that
is  satisfactory  to  the  Administrative  Agent,  that  will  continue  to  provide  LIBOR  after  such  specific  date  (such
specific date, the “Scheduled Unavailability Date”), or

(iii)        syndicated  loans  currently  being  executed,  or  that  include  language  similar  to  that  contained  in  this
Section 3.03, are being executed or amended (as applicable) to incorporate or adopt a new benchmark interest rate to
replace LIBOR,

then,  reasonably  promptly  after  such  determination  by  the  Administrative  Agent  or  receipt  by  the  Administrative
Agent  of  such  notice,  as  applicable,  the  Administrative  Agent  and  the  Company  may  amend  this  Agreement  to  replace
LIBOR in  accordance with  this  Section  3.03  with  (x)  one  or  more  SOFR-Based  Rates  (which  shall  be  applicable  only  to
Loans  denominated  in  Dollars)  or  (y)  another  alternate  benchmark  rate  giving  due  consideration  to  any  evolving  or  then
existing convention for similar U.S. dollarDollar  denominated  syndicated  credit  facilities  for  such  alternative  benchmarks
and,  in  each  case,  including  any  mathematical  or  other  adjustments  to  such  benchmark  giving  due  consideration  to  any
evolving  or  then  existing  convention  for  similar  U.S.  dollarDollar  denominated  syndicated  credit  facilities  for  such
benchmarks, which adjustment or method for calculating such adjustment shall be published on an information service as
selected by the Administrative Agent from time to time in its reasonable discretion and may be periodically updated (the
“Adjustment”; and any such proposed rate, a “LIBOR Successor Rate”), and any such amendment shall become effective at
5:00  p.m.  on  the  fifth  Business  Day  after  the  Administrative  Agent  shall  have  posted  such  proposed  amendment  to  all
Lenders  and  the  Company  unless,  prior  to  such  time,  Lenders  comprising  the  Required  Lenders  have  delivered  to  the
Administrative Agent written

notice that such Required Lenders (A) in the case of an amendment to replace LIBOR with a rate described in clause (x),
object to the Adjustment; or (B) in the case of an amendment to replace LIBOR with a rate described in clause (y), object to
such amendment; provided  that  for  the  avoidance  of  doubt,  in  the  case  of  clause  (A),  the  Required  Lenders  shall  not  be
entitled to object to any SOFR-Based Rate contained in any such amendment. Such LIBOR Successor Rate shall be applied
in a manner consistent with market practice; provided that to the extent such market practice is not administratively feasible
for the Administrative Agent, such LIBOR Successor Rate shall be applied in a manner as otherwise reasonably determined
by the Administrative Agent.

If  no  LIBOR  Successor  Rate  has  been  determined  and  the  circumstances  under  clause  (c)(i)  above  exist  or  the
Scheduled Unavailability Date has occurred (as applicable), the Administrative Agent will promptly so notify the Company
and each Lender. Thereafter, (i) the obligation of the Lenders to make or maintain Eurocurrency Rate Loans in the affected
currency or currencies shall be suspended (to the extent of the affected Eurocurrency Rate Loans or Interest Periods), and
(ii) the Eurocurrency Rate component shall no longer be utilized in determining the Base Rate. Upon receipt of such notice,
the  Company  may  revoke  any  pending  request  for  a  Borrowing  of,  conversion  to  or  continuation  of  Eurocurrency  Rate
Loans in the affected currency or currencies (to the extent of the affected Eurocurrency Rate Loans or Interest Periods) or,
failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans (subject to the
foregoing clause (ii)) in Dollars in the amount specified therein.

Notwithstanding anything else herein, any definition of LIBOR Successor Rate shall provide that in no event shall

such LIBOR Successor Rate be less than zero for purposes of this Agreement.

In connection with the implementation of a LIBOR Successor Rate, the Administrative Agent will have the right to
make LIBOR Successor Rate Conforming Changes from time to time and, notwithstanding anything to the contrary herein
or  in  any  other  Loan  Document,  any  amendments  implementing  such  LIBOR  Successor  Rate  Conforming  Changes  will
become effective without any further action or consent of any other party to this Agreement.; provided that, with respect to
any such amendment effected, the Administrative Agent shall post each such amendment implementing LIBOR Successor
Rate Conforming Changes to the Company and the Lenders reasonably promptly after such amendment becomes effective.

For purposes hereof:

“LIBOR  Successor  Rate  Conforming  Changes”  means,  with  respect  to  any  proposed  LIBOR  Successor  Rate,  any
conforming changes to the definition of Base Rate, Interest Period, timing and frequency of determining rates and making
payments of interest and other technical, administrative or operational matters as may be appropriate, in the discretion of the
Administrative  Agent,  to  reflect  the  adoption  and  implementation  of  such  LIBOR  Successor  Rate  and  to  permit  the
administration thereof by the

Administrative Agent in a manner substantially consistent with market practice (or, if the Administrative Agent determines
that  adoption  of  any  portion  of  such  market  practice  is  not  administratively  feasible  or  that  no  market  practice  for  the
administration of such LIBOR Successor Rate exists, in such other manner of administration as the Administrative Agent
determines is reasonably necessary in connection with the administration of this Agreement).

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or
a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York
for the purpose of recommending a benchmark rate to replace LIBOR in loan agreements similar to this Agreement.

“SOFR” with respect to any day means the secured overnight financing rate published for such day by the Federal
Reserve Bank of New York, as the administrator of the benchmark (or a successor administrator) on the Federal Reserve
Bank  of  New  York’s  website  (or  any  successor  source)  and,  in  each  case,  that  has  been  selected  or  recommended  by  the
Relevant Governmental Body.

“SOFR-Based Rate” means SOFR or Term SOFR.

“Term  SOFR”  means  the  forward-looking  term  rate  for  any  period  that  is  approximately  (as  determined  by  the
Administrative Agent) as long as any of the Interest Period options set forth in the definition of “Interest Period” and that is
based on SOFR and that has been selected or recommended by the Relevant Governmental Body, in each case as published
on an information service as selected by the Administrative Agent from time to time in its reasonable discretion.

3.04    Increased Costs; Reserves on Eurocurrency Rate Loans.

(a)    Increased Costs Generally. If any Change in Law shall:

(i)    impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or
similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any
Lender (except any reserve requirement contemplated by Section 3.04(e)) or any L/C Issuer;

(ii)    subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Excluded Taxes (other than
those described in clause (a) of the definition of Excluded Taxes) and (C) Connection Income Taxes) on its loans,
loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital
attributable thereto; or

(iii)    impose on any Lender or any L/C Issuer or the London interbank market any other condition, cost or

expense affecting this Agreement or

Eurocurrency Rate Loans made by such Lender or any Letter of Credit or participation therein;

and  the  result  of  any  of  the  foregoing  shall  be  to  increase  the  cost  to  such  Lender  of  making,  converting  to,  continuing  or
maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or such L/C
Issuer of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue
any  Letter  of  Credit),  or  to  reduce  the  amount  of  any  sum  received  or  receivable  by  such  Lender  or  such  L/C  Issuer  hereunder
(whether of principal, interest or any other amount) then, upon request of such Lender or such L/C Issuer, the Company will pay (or
cause the applicable Designated Foreign Borrower to pay) to such Lender or such L/C Issuer, as the case may be, such additional
amount or amounts as will compensate such Lender or such L/C Issuer, as the case may be, for such additional costs incurred or
reduction suffered.

(b)        Capital  Requirements.  If  any  Lender  or  any  L/C  Issuer  determines  that  any  Change  in  Law  affecting  such
Lender or such L/C Issuer or any Lending Office of such Lender or such Lender’s or such L/C Issuer’s holding company, if
any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s
or  such  L/C  Issuer’s  capital  or  on  the  capital  of  such  Lender’s  or  such  L/C  Issuer’s  holding  company,  if  any,  as  a
consequence  of  this  Agreement,  the  Revolving  Commitments  of  such  Lender  or  the  Loans  made  by,  or  participations  in
Letters  of  Credit  or  Swingline  Loans  held  by,  such  Lender,  or  the  Letters  of  Credit  issued  by  such  L/C  Issuer,  to  a  level
below  that  which  such  Lender  or  such  L/C  Issuer  or  such  Lender’s  or  such  L/C  Issuer’s  holding  company  could  have
achieved but for such Change in Law (taking into consideration such Lender’s or such L/C Issuer’s policies and the policies
of such Lender’s or such L/C Issuer’s holding company with respect to capital adequacy or liquidity), then from time to time
the Company will pay (or cause the applicable Designated Foreign Borrower to pay) to such Lender or such L/C Issuer, as
the case may be, such additional amount or amounts as will compensate such Lender or such L/C Issuer or such Lender’s or
such L/C Issuer’s holding company for any such reduction suffered.

(c)    [Reserved].

(d)    Certificates for Reimbursement. A certificate of a Lender or an L/C Issuer setting forth in reasonable detail the
amount or amounts necessary to compensate such Lender or such L/C Issuer or its holding company, as the case may be, as
specified  in  clause  (a)  or  (b)  of  this  Section  3.04,  including  the  basis  and  calculation  thereof,  shall  be  delivered  to  the
Company and shall be conclusive absent manifest error. The Company shall pay (or cause the applicable Designated Foreign
Borrower  to  pay)  such  Lender  or  such  L/C  Issuer,  as  the  case  may  be,  the  amount  shown  as  due  on  any  such  certificate
within ten (10) days after receipt thereof.

(e)    Reserves on Eurocurrency Rate Loans. The Company shall pay (or cause the applicable Designated Foreign
Borrower to pay) to each Lender, (i) as long as such Lender shall be required to maintain reserves with respect to liabilities
or assets

consisting of or including eurocurrency funds or deposits (currently known as “Eurocurrency liabilities”), additional interest
on the unpaid principal amount of each Eurocurrency Rate Loan equal to the actual costs of such reserves allocated to such
Loan by such Lender (as determined by such Lender in good faith, which determination shall be conclusive) and (ii) as long
as  such  Lender  shall  be  required  to  comply  with  any  reserve  ratio  requirement  or  analogous  requirement  of  any  central
banking  or  financial  regulatory  authority  imposed  in  respect  of  the  maintenance  of  the  Revolving  Commitments  or  the
funding of the Loans, such additional costs (expressed as a percentage per annum and rounded upwards, if necessary, to the
nearest five decimal places) equal to the actual costs allocated to such Revolving Commitment or Loan by such Lender (as
determined  by  such  Lender  in  good  faith,  which  determination  shall  be  conclusive),  which  in  each  case  shall  be  due  and
payable on each date on which interest is payable on such Loan, provided the Company shall have received at least ten (10)
days’  prior  notice  (with  a  copy  to  the  Administrative  Agent)  of  such  additional  interest  or  costs  from  such  Lender.  If  a
Lender fails to give notice ten (10) days prior to the relevant Interest Payment Date, such additional interest shall be due and
payable ten (10) days from receipt of such notice.

(f)        Delay  in  Requests.  Failure  or  delay  on  the  part  of  any  Lender  or  any  L/C  Issuer  to  demand  compensation
pursuant to the foregoing provisions of this Section 3.04 shall not constitute a waiver of such Lender’s or such L/C Issuer’s
right to demand such compensation, provided that the Borrowers shall not be required to compensate a Lender or an L/C
Issuer pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than
nine  (9)  months  prior  to  the  date  that  such  Lender  or  such  L/C  Issuer,  as  the  case  may  be,  notifies  the  Company  of  the
Change in Law giving rise to such increased costs or reductions and of such Lender’s or such L/C Issuer’s intention to claim
compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then
the nine (9) month period referred to above shall be extended to include the period of retroactive effect thereof).

3.05    Compensation for Losses.

Upon written demand of any Lender (with a copy to the Administrative Agent) from time to time, setting forth in reasonable
detail the basis for, and manner of calculating such compensation, the Company shall promptly compensate (or cause the applicable
Designated  Foreign  Borrower  to  compensate)  such  Lender  for  and  hold  such  Lender  harmless  from  any  loss,  cost  or  expense
incurred by it as a result of:

(a)    any continuation, conversion, payment or prepayment of any Loan other than a Base Rate Loan on a day other
than the last day of the Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of acceleration, or
otherwise);

(b)    any failure by the Borrowers (for a reason other than the failure of such Lender to make a Loan) to prepay,

borrow, continue or convert any Loan other than a

Base Rate Loan on the date or in the amount notified by the Company (or the applicable Designated Foreign Borrower);

(c)    any assignment of a Eurocurrency Rate Loan on a day other than the last day of the Interest Period therefor as a

result of a request by the Company pursuant to Section 11.13; or

(d)    any failure by any Borrower to make payment of any Loan or drawing under any Letter of Credit (or interest
due  thereon)  denominated  in  an  Alternative  Currency  on  its  scheduled  due  date  or  any  payment  thereof  in  a  different
currency;

including  any  foreign  exchange  losses  and  any  loss  or  expense  (but  excluding  any  loss  of  anticipated  profits)  arising  from  the
liquidation  or  reemployment  of  funds  obtained  by  it  to  maintain  such  Loan  or  from  fees  payable  to  terminate  the  deposits  from
which such funds were obtained or from the performance of any foreign exchange contract (but excluding any loss of anticipated
profits). The Company shall also pay (or cause the applicable Designated Foreign Borrower to pay) any customer administrative
fees charged by such Lender in connection with the foregoing.

For  purposes  of  calculating  amounts  payable  by  the  Company  (or  the  applicable  Designated  Foreign  Borrower)  to  the  Lenders
under this Section 3.05, each Lender shall be deemed to have funded each Eurocurrency Rate Loan made by it at the Eurocurrency
Rate for such Loan by a matching deposit or other borrowing in the offshore interbank market for such currency for a comparable
amount and for a comparable period, whether or not such Eurocurrency Rate Loan was in fact so funded.

3.06    Mitigation Obligations; Replacement of Lenders.

(a)    Designation of a Different Lending Office. If any Lender requests compensation under Section 3.04, or requires
the  Borrowers  to  pay  any  Indemnified  Taxes  or  additional  amounts  to  any  Lender,  any  L/C  Issuer,  or  any  Governmental
Authority for the account of any Lender or any L/C Issuer pursuant to Section 3.01, or if any Lender gives a notice pursuant
to  Section  3.02,  then  at  the  request  of  the  Company,  such  Lender  or  such  L/C  Issuer  shall,  as  applicable,  use  reasonable
efforts  to  designate  a  different  Lending  Office  for  funding  or  booking  its  Loans  hereunder  or  to  assign  its  rights  and
obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender or such L/C Issuer,
such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04, as the case
may be, in the future, or eliminate the need for the notice pursuant to Section 3.02, as applicable, and (ii) in each case, would
not  subject  such  Lender  or  such  L/C  Issuer,  as  the  case  may  be,  to  any  unreimbursed  cost  or  expense  and  would  not
otherwise be disadvantageous to such Lender or such L/C Issuer, as the case may be. The Company hereby agrees to pay (or
cause the applicable Designated Foreign Borrower to pay) all reasonable costs and expenses incurred by any Lender or any
L/C Issuer in connection with any such designation or assignment.

(b)        Replacement  of  Lenders.  If  any  Lender  requests  compensation  under  Section  3.04,  or  if  the  Borrowers  are
required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account
of  any  Lender  pursuant  to  Section  3.01  and,  in  each  case,  such  Lender  has  declined  or  is  unable  to  designate  a  different
lending office in accordance with Section 3.06(a), the Company may replace such Lender in accordance with Section 11.13.

3.07    Survival.

All of the Borrowers’ obligations under this Article III and the Lenders’ obligations under Section 3.01(c)(ii) shall, in each
case, survive termination of the Aggregate Revolving Commitments, repayment of all other Obligations hereunder, resignation of
the Administrative Agent and the Facility Termination Date.

4.01    Conditions of Initial Credit Extension.

made; it being understood and recognized by the Administrative Agent and the Lenders that such projections are as to future
events and are not to be viewed as facts, the forecasts and projections are as to future events, and not to be viewed as facts
and are subject to significant uncertainties and contingencies, many of which are beyond the control of the Company and its
Restricted Subsidiaries, that no assurance can be given that any particular projections will be realized and that actual results
during the period or periods covered by any such projections may differ significantly from the projected results and such
differences may be material.

5.06    Litigation.

There are no actions, suits, proceedings, claims or disputes pending or, to the knowledge of the Loan Parties, threatened in
writing,  at  law,  in  equity,  in  arbitration  or  before  any  Governmental  Authority,  by  or  against  the  Company  or  any  Restricted
Subsidiary or against any of their properties or revenues that (a) purport to affect or pertain to this Agreement or any other Loan

Agreement or any other Loan Document.

5.08    Ownership of Property.

interests in, all real property necessary or material to the present conduct of its business, in each case, except for defects in title that
do not materially interfere with its ability to conduct its business or to utilize such properties for their intended purposes or where
the  failure  to  have  such  title  or  interests  would  not,  individually  or  in  the  aggregate,  reasonably  be  expected  to  have  a  Material
Adverse Effect.

5.09    Environmental Compliance.

The Loan Parties and their respective Restricted Subsidiaries (ia) are in compliance with applicable Environmental Laws,
which  compliance  includes  possession  of  and  compliance  with  all  required  Environmental  Permits,  (iib)  are  not  subject  to  any
Environmental Liability, and (iiic) have not received written notice of any claim pursuant to Environmental Laws or with respect to
the release of or exposure to Hazardous Materials, excluding any matters with respect to the foregoing that would not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

5.10    Insurance.

The properties of the Company and its Restricted Subsidiaries are insured with financially sound and reputable insurance
companies,  in  such  amounts  (after  giving  effect  to  any  self-insurance  compatible  with  the  following  standards),  with  such
deductibles  and  covering  such  risks  as  are  customarily  carried  by  companies  of  a  similar  size  engaged  in  similar  businesses  and
owning similar properties.

federal income Taxes

and other material Taxes required to be paid by it except (ia) those which are not overdue for a period of more than thirty (30) days,
so long as the failure to make any such payment during such thirty (30-) day period would not reasonably be expected to have a
Material Adverse Effect, or (iib) those which are being contested in good faith by appropriate proceedings and for which adequate
reserves have been provided in accordance with GAAP. There is no proposed tax assessment against any Loan Party or any of their
respective  Restricted  Subsidiaries  that  would,  if  made,  have  a  Material  Adverse  Effect,  nor  is  there  any  tax  sharing  agreement
applicable  to  any  Loan  Party  or  any  of  their  respective  Restricted  Subsidiaries  other  than  an  agreement  solely  among  any  of  the
Company and its Subsidiaries.

The Company is not required to make any deduction on account of Irish tax from any payment it may make under any Loan
Document to a Lender which is an Irish Qualifying Lender subject, in the case of an Irish Treaty Lender, to the completion of any
necessary procedural formalities.

No Loan Party is required to make any UK Tax Deduction from any payment it may make under a Loan Document to a
Lender which is (a) a UK Qualifying Lender (i) falling within paragraph (a) of the definition of “UK Qualifying Lender” or (ii)
except where a UK Direction has been given under Section 931 of the UK Taxes Act in relation to the payment concerned, falling
within paragraph (b) of the definition of “UK Qualifying Lender”, or (b) a UK Treaty Lender and the payment is one specified in a
direction  given  by  the  Commissioners  of  Revenue  and  Customs  under  Regulation  2  of  the  Double  Taxation  Relief  (Taxes  on
Income) (General) Regulations 1970 (SI 1970/488).

5.12    ERISA Compliance.

(a)    Each Plan is in compliance in all material respects with the applicable provisions of ERISA, the Code and other
federal or state laws except for instances of noncompliance that, either individually or in the aggregate, have not resulted or
would not reasonably be expected to result in a Material Adverse Effect. Each Pension Plan that is intended to be a qualified
plan under Section 401(a) of the Code has received a favorable determination letter or is subject to a favorable opinion letter
from  the  IRS  to  the  effect  that  the  form  of  such  Plan  is  qualified  under  Section  401(a)  of  the  Code  and  the  trust  related
thereto  has  been  determined  by  the  IRS  to  be  exempt  from  federal  income  tax  under  Section  501(a)  of  the  Code,  or  an
application for such a letter is currently being processed by the IRS. To the best knowledge of the Loan Parties, nothing has
occurred  that  would  prevent  or  cause  the  loss  of  such  tax-qualified  status  other  than  qualification  defects  that  can  be
corrected  under  the  Employee  Plans  Compliance  Resolution  System  described  in  IRS  Revenue  Procedure  2019-19  where
such correction would not be expected to result in a Material Adverse Effect.

(b)    There are no pending or, to the knowledge of the Loan Parties, threatened claims, actions or lawsuits, or action
by  any  Governmental  Authority,  with  respect  to  any  Plan  that  would  reasonably  be  expected  to  have  a  Material  Adverse
Effect. There has been no prohibited transaction or violation of the fiduciary responsibility rules with

respect to any Plan that has resulted or would reasonably be expected to result in a Material Adverse Effect.

(c)        Except  as  would  not,  either  individually  or  in  the  aggregate,  reasonably  be  expected  to  result  in,  a  Material
Adverse Effect: (i) no ERISA Event has occurred, and no Loan Party nor any ERISA Affiliate is aware of any fact, event or
circumstance that would reasonably be expected to constitute or result in an ERISA Event with respect to any Pension Plan
or  Multiemployer  Plan;  (ii)  as  of  the  most  recent  valuation  date  for  any  Pension  Plan,  the  funding  target  attainment
percentage (as defined in Section 430(d)(2) of the Code) is 60% or higher and no Loan Party nor any ERISA Affiliate knows
of any facts or circumstances that would reasonably be expected to cause the funding target attainment percentage for any
such plan to drop below 60% as of the most recent valuation date; (iii) no Loan Party nor any ERISA Affiliate has incurred
any liability to the PBGC other than for the payment of premiums, and there are no premium payments which have become
due that are unpaid; (iv) neither the Company nor any ERISA Affiliate has engaged in a transaction that could be subject to
Section 4069 or Section 4212(c) of ERISA; and (v) no Pension Plan has been terminated by the plan administrator thereof
nor by the PBGC, and no event or circumstance has occurred or exists that would reasonably be expected to cause the PBGC
to institute proceedings under Title IV of ERISA to terminate any Pension Plan.

(d)        With  respect  to  each  scheme  or  arrangement  mandated  by  a  government  other  than  the  United  States  (a
“Foreign Government Scheme or Arrangement”) and with respect to each employee benefit plan maintained or contributed
to by any Loan Party or any of their respective Restricted Subsidiaries that is not subject to United States Law (a “Foreign
Plan”), except as would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect:

(i)    any employer and employee contributions required by law or by the terms of any Foreign Government
Scheme or Arrangement or any Foreign Plan have been made, or, if applicable, accrued, in accordance with normal
accounting practices of the jurisdiction in which such plan is maintained;

(ii)    the Fair Market Value of the assets of each funded Foreign Plan, the liability of each insurer for any
Foreign  Plan  funded  through  insurance  or  the  book  reserve  established  for  any  Foreign  Plan,  together  with  any
accrued contributions, is sufficient to procure or provide for the accrued benefit obligations, as of the date hereof,
with respect to all current and former participants in such Foreign Plan according to the actuarial assumptions and
valuations  most  recently  used  to  account  for  such  obligations  in  accordance  with  applicable  generally  accepted
accounting principles of the jurisdiction in which such plan is maintained; and

(iii)        each  Foreign  Plan  required  to  be  registered  has  been  registered  and  has  been  maintained  in  good

standing with applicable regulatory authorities.

contemplated  hereby  or  thereby  or  delivered  hereunder  or  thereunder  (in  each  case  as  modified  or  supplemented  by  other
information so furnished) when taken as a whole, together with disclosures made by the Company in filings with the SEC that are
made  available  to  the  Administrative  Agent  and  the  Lenders  pursuant  to  the  terms  of  this  Agreement,  contains  any  material
misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not materially misleading; provided that, with respect to projected financial information, each Loan
Party represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time
made; it being understood (a) that such projections and forecasts are as to future events and are not to be viewed as facts, that such
projections are subject to significant uncertainties and contingencies, many of which are beyond the control of the Company and its
Subsidiaries, that no assurance can be given that any particular projection or forecast will be realized and that actual results during
the  period  or  periods  covered  by  any  such  projections  or  forecasts  may  differ  significantly  from  the  projected  results  and  such

Notwithstanding anything to the contrary in this Section 6.02, no Loan Party shall be required to provide any information in respect
of which disclosure is prohibited by any applicable Laws binding on such Loan Party.

and the L/C Issuers under the Loan Documents or applicable Law or equity;

provided, however, that upon the occurrence of an actual or deemed entry of an order for relief with respect to the Borrowers under
the Bankruptcy Code of the United States, the obligation of each Lender to make Loans and any obligation of any L/C Issuer to
make L/C Credit Extensions shall automatically terminate, the unpaid principal amount of all outstanding Loans and all interest and
other amounts as aforesaid shall automatically become due and payable, and the obligation of the Borrowers to Cash Collateralize
the L/C Obligations as aforesaid shall automatically become effective, in each case without further act of the Administrative Agent
or any Lender.

8.03    Application of Funds.

After the exercise of remedies provided for in Section 8.02 (or after the Loans have automatically become immediately due

and payable and the L/C Obligations have automatically

been required to be Cash Collateralized as set forth in the proviso to Section 8.02) or if at any time insufficient funds are received
by and available to the Administrative Agent to pay fully all Guaranteed Obligations then due hereunder, any amounts received on
account of the Guaranteed Obligations shall, subject to the provisions of Sections 2.14 and 2.15, be applied by the Administrative
Agent in the following order:

First,  to  payment  of  that  portion  of  the  Guaranteed  Obligations  constituting  fees,  indemnities,  expenses  and  other
amounts  (including  fees,  charges  and  disbursements  of  counsel  to  the  Administrative  Agent  and  amounts  payable  under
Article III) payable to the Administrative Agent in its capacity as such;

Second, to payment of that portion of the Guaranteed Obligations constituting fees, indemnities and other amounts
(other than principal, interest and Letter of Credit Fees) payable to the Lenders, and the L/C Issuers (including fees, charges
and disbursements of counsel to the respective Lenders, and the L/C Issuers arising under the Loan Documents and amounts
payable  under  Article  III),  ratably  among  them  in  proportion  to  the  respective  amounts  described  in  this  clause  Second
payable to them;

Third,  to  payment  of  that  portion  of  the  Guaranteed  Obligations  constituting  accrued  and  unpaid  Letter  of  Credit
Fees  and  interest  on  the  Loans,  L/C  Borrowings  and  other  Guaranteed  Obligations  arising  under  the  Loan  Documents,
ratably  among  the  Lenders  and  the  L/C  Issuers  in  proportion  to  the  respective  amounts  described  in  this  clause  Third
payable to them;

Fourth, to payment of that portion of the Guaranteed Obligations constituting unpaid principal of the Loans and L/C
Borrowings and to the Administrative Agent for the account of the L/C Issuers, to Cash Collateralize that portion of L/C
Obligations comprised of the aggregate undrawn amount of Letters of Credit to the extent not otherwise Cash Collateralized
by the Borrowers pursuant to Sections 2.03 and 2.14, in each case ratably among the Administrative Agent, the Lenders and
the L/C Issuers in proportion to the respective amounts described in this clause Fourth held by them;

Fifth, to payment of that portion of the Guaranteed Obligations then owing under the Guaranteed Hedge Agreements
and Guaranteed Cash Management Agreements, in each case ratably among the Hedge Banks and the Cash Management
Banks in proportion to the respective amounts described in this clause Fifth held by them; and

Last, the balance, if any, after all of the Guaranteed Obligations have been indefeasibly paid in full, to the Borrowers

or as otherwise required by Law.

Subject  to  Sections  2.03(c)  and  2.14,  amounts  used  to  Cash  Collateralize  the  aggregate  undrawn  amount  of  Letters  of  Credit
pursuant  to  clause  Fourth  above  shall  be  applied  to  satisfy  drawings  under  such  Letters  of  Credit  as  they  occur.  If  any  amount
remains on deposit as Cash Collateral after all Letters of Credit have either been fully drawn or expired, such remaining amount
shall be applied to the other Guaranteed Obligations, if any, in the order set forth above. Excluded Swap Obligations with respect to
any Guarantor shall not be paid with amounts received from

such  Guarantor  or  its  assets,  but  appropriate  adjustments  shall  be  made  with  respect  to  payments  from  other  Loan  Parties  to
preserve the allocation to Guaranteed Obligations otherwise set forth above in this Section.

Notwithstanding  the  foregoing,  (a)  Guaranteed  Obligations  arising  under  Guaranteed  Cash  Management  Agreements  and
Guaranteed Hedge Agreements shall be excluded from the application described above if the Administrative Agent has not received
a Guaranteed Party Designation Notice, together with such supporting documentation as the Administrative Agent may reasonably
request, from the applicable Cash Management Bank or Hedge Bank, as the case may be, and (b) no amounts received from or on
account of a Designated Foreign Borrower shall be used to pay or applied against any Guaranteed Obligations of or attributable to
any U.S. Loan Party or any other Domestic Subsidiary. Each Cash Management Bank or Hedge Bank not a party to this Agreement
that  has  given  the  notice  contemplated  by  the  preceding  sentence  shall,  by  such  notice,  be  deemed  to  have  acknowledged  and
accepted the appointment of the Administrative Agent pursuant to the terms of Article IX for itself and its Affiliates as if a “Lender”

act  on  its  behalf  as  the  Administrative  Agent  hereunder  and  under  the  other  Loan  Documents  and  authorizes  the  Administrative
Agent  to  take  such  actions  on  its  behalf  and  to  exercise  such  powers  as  are  delegated  to  the  Administrative  Agent  by  the  terms
hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article IX are
solely for the benefit of the Administrative Agent, the Lenders and the L/C Issuers, and neither the Borrowers nor any other Loan
Party shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term
“agent”  herein  or  in  any  other  Loan  Documents  (or  any  other  similar  term)  with  reference  to  the  Administrative  Agent  is  not
intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Law.
Instead  such  term  is  used  as  a  matter  of  market  custom,  and  is  intended  to  create  or  reflect  only  an  administrative  relationship
between contracting parties.

9.02    Rights as a Lender.

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender
as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders”
shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative
Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities
of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of banking, trust, financial,

advisory, underwriting or other business with any Loan Party or any Subsidiary or other Affiliate thereof as if such Person were not
the Administrative Agent hereunder and without any duty to account therefor to the Lenders or to provide notice to or consent of the
Lenders with respect thereto.

9.03    Exculpatory Provisions.

(a)    The Administrative Agent or the Arrangers, as applicable, shall not have any duties or obligations except those

in nature. Without limiting the generality of the foregoing, the Administrative Agent and itsor the Arrangers, as applicable,
and their Related Parties:

and is continuing;

(ii)    shall not have any duty to take any discretionary action or exercise any discretionary powers, except
discretionary  rights  and  powers  expressly  contemplated  hereby  or  by  the  other  Loan  Documents  that  the
Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or
percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that
the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel,
may  expose  the  Administrative  Agent  to  liability  or  that  is  contrary  to  any  Loan  Document  or  applicable  Law,
including  for  the  avoidance  of  doubt  any  action  that  may  be  in  violation  of  the  automatic  stay  under  any  Debtor
Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation

9.04    Reliance by Administrative Agent.

The  Administrative  Agent  shall  be  entitled  to  rely  upon,  and  shall  be  fully  protected  in  relying  and  shall  not  incur  any
liability for relying upon, any notice, request, certificate, communication, consent, statement, instrument, document or other writing
(including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have
been  signed,  sent  or  otherwise  authenticated  by  the  proper  Person.  The  Administrative  Agent  also  may  rely  upon  any  statement
made to it orally or by telephone and believed by it to have been made by the proper Person, and shall be fully protected in relying
and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a
Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a
Lender  or  an  L/C  Issuer,  the  Administrative  Agent  may  presume  that  such  condition  is  satisfactory  to  such  Lender  or  such  L/C
Issuer unless the Administrative Agent shall have received notice to the contrary from such Lender or such L/C Issuer prior to the
making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may
be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable

for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. For purposes of
determining compliance with the conditions specified in Section 4.01, each Lender that has signed this Agreement shall be deemed
to  have  consented  to,  approved  or  accepted  or  to  be  satisfied  with,  each  document  or  other  matter  required  thereunder  to  be
consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received notice
from such Lender prior to the proposed Closing Date specifying its objections.

9.05    Delegation of Duties.

The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any
other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent
and  any  such  sub-agent  may  perform  any  and  all  of  its  duties  and  exercise  its  rights  and  powers  by  or  through  their  respective
Related Parties. The exculpatory provisions of this Article IX shall apply to any such sub-agent and to the Related Parties of the
Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the
Revolving  Facility  as  well  as  activities  as  Administrative  Agent.  The  Administrative  Agent  shall  not  be  responsible  for  the
negligence  or  misconduct  of  any  sub-agents  except  to  the  extent  that  a  court  of  competent  jurisdiction  determines  in  a  final  and
nonappealable judgment that the Administrative Agent acted with gross negligence, willful misconduct or bad faith in the selection
of such sub-agents.

9.06    Resignation of Administrative Agent.

(a)    Notice. The Administrative Agent may at any time give notice of its resignation to the Lenders, the L/C Issuers
and the Company. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation
with the Company, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any
such bank with an office in the United States, and in each case such successor shall require the consent of the Company at
all  times  other  than  during  the  existence  of  an  Event  of  Default  under  Section  8.01(a)  or  8.01(f)  (such  consent  not  to  be
unreasonably withheld or delayed). If  no  such  successor  shall  have  been  so  appointed  by  the  Required  Lenders  and  shall
have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation
(or  such  earlier  day  as  shall  be  agreed  by  the  Required  Lenders)  (the  “Resignation  Effective  Date”),  then  the  retiring
Administrative Agent may (but shall not be obligated to) on behalf of the Lenders and the L/C Issuers, appoint a successor
Administrative  Agent  meeting  the  qualifications  set  forth  above;  provided  that  in  no  event  shall  any  successor
Administrative Agent be a Defaulting Lender or a Disqualified Institution. Whether or not a successor has been appointed,
such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b)    Defaulting Lender. If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d)
of the definition thereof, the Required Lenders may, to the extent permitted by applicable Law, by notice in writing to the
Company and

such Person remove such Person as Administrative Agent and, in consultation with the Company, appoint a successor. If no
such  successor  shall  have  been  so  appointed  by  the  Required  Lenders  and  shall  have  accepted  such  appointment  within
thirty (30) days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such
removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c)    Effect of Resignation or Removal. With effect from the Resignation Effective Date or the Removal Effective
Date  (as  applicable)  (i)  the  retiring  or  removed  Administrative  Agent  shall  be  discharged  from  its  duties  and  obligations
hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative
Agent on behalf of the Lenders or the L/C Issuers under any of the Loan Documents, the retiring or removed Administrative
Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and
(ii)  except  for  any  indemnity  payments  or  other  amounts  then  owed  to  the  retiring  or  removed  Administrative  Agent,  all
payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead
be  made  by  or  to  each  Lender  and  each  L/C  Issuer  directly,  until  such  time,  if  any,  as  the  Required  Lenders  appoint  a
successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative
Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of
the  retiring  (or  removed)  Administrative  Agent  (other  than  as  provided  in  Section  3.01(j)  and  other  than  any  rights  to
indemnity payments or other amounts owed to the retiring or removed Administrative Agent as of the Resignation Effective
Date or the Removal Effective Date, as applicable), and the retiring or removed Administrative Agent shall be discharged
from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as
provided above in this Section). The fees payable by the Company to a successor Administrative Agent shall be the same as
those  payable  to  its  predecessor  unless  otherwise  agreed  between  the  Company  and  such  successor,  and  the  retiring  or
removed Administrative Agent shall cease to be entitled to all such fees upon the effectiveness of its resignation or removal
as  Administrative  Agent,  except  to  the  extent  it  continues  to  act  in  any  capacity  hereunder  or  under  the  other  Loan
Documents after such resignation or removal. After the retiring or removed Administrative Agent’s resignation or removal
hereunder and under the other Loan Documents, the provisions of this Article XI and Section 11.04 shall continue in effect
for  the  benefit  of  such  retiring  or  removed  Administrative  Agent,  its  sub-agents  and  their  respective  Related  Parties  in
respect of any actions taken or omitted to be taken by any of them (A) while the retiring or removed Administrative Agent
was acting as Administrative Agent and (B) after such resignation or removal for as long as any of them continues to act in
any capacity hereunder or under the other Loan Documents, including, without limitation, (1) acting as collateral agent or
otherwise  holding  any  collateral  security  on  behalf  of  any  of  the  Credit  Parties  and  (2)  in  respect  of  any  actions  taken  in
connection with transferring the agency to any successor Administrative Agent.

(d)    L/C Issuer and Swingline Lender. Any resignation or removal by Bank of America as Administrative Agent
pursuant to this Section 9.06 shall also constitute its resignation as an L/C Issuer and Swingline Lender. If Bank of America
resigns as an L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuers hereunder with respect
to  all  Letters  of  Credit  issued  by  it  outstanding  as  of  the  effective  date  of  its  resignation  as  an  L/C  Issuer  and  all  L/C
Obligations  with  respect  thereto,  including  the  right  to  require  the  Lenders  to  make  Base  Rate  Loans  or  fund  risk
participations  in  Unreimbursed  Amounts  pursuant  to  Section  2.03(c).  If  Bank  of  America  resigns  as  Swingline  Lender,  it
shall retain all the rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and
outstanding as of the effective date of such resignation, including the right to require the Lenders to make Base Rate Loans
or  fund  risk  participations  in  outstanding  Swingline  Loans  pursuant  to  Section  2.04(c).  Upon  the  appointment  by  the
Company of a successor L/C Issuer or Swingline Lender hereunder (which successor shall in all cases be a Lender other
than a Defaulting Lender), (i) such successor shall succeed to and become vested with all of the rights, powers, privileges
and duties of the retiring L/C Issuer or Swingline Lender, as applicable, (ii) the retiring L/C Issuer and Swingline Lender
shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and
(iii) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the
time of such succession or make other arrangements satisfactory to Bank of America to effectively assume the obligations of
Bank of America with respect to such Letters of Credit.

9.07    Non-Reliance on Administrative Agent, the Arrangers and the Other Lenders.

Each Lender and each L/C Issuer expressly acknowledges that none of the Administrative Agent nor the Arrangers has made
any  representation  or  warranty  to  it,  and  that  no  act  by  the  Administrative  Agent  or  any  Arranger  hereafter  taken,  including  any
consent to, and acceptance of any assignment or review of the affairs of any Loan Party or any Affiliate thereof, shall be deemed to
constitute any representation or warranty by the Administrative Agent or any Arranger to any Lender or each L/C Issuer as to any
matter, including whether the Administrative Agent or any Arranger has disclosed material information in their (or their Related
Parties’)  possession.  Each  Lender  and  each  L/C  Issuer  represents  to  the  Administrative  Agent  and  the  Arrangers  that  it  has,
independently  and  without  reliance  upon  the  Administrative  Agent  or,  the  Arrangers,  any  other  Lender  or  any  of  their  Related
Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis andof, appraisal of,
and investigation into, the business, prospects, operations, property, financial and other condition and creditworthiness of the Loan
Parties and their Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and
made its own  decision  to  enter  into  this  Agreement  and  to  extend  credit  to  the  Borrower  hereunder.  Each  Lender  and  each  L/C
Issuer  also  acknowledges  that  it  will,  independently  and  without  reliance  upon  the  Administrative  Agent  or,  the  Arrangers,  any
other  Lender  or  any  of  their  Related  Parties  and  based  on  such  documents  and  information  as  it  shall  from  time  to  time  deem
appropriate, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under or based upon
this Agreement, any other Loan Document or any related agreement or any

document  furnished  hereunder  or  thereunder.,  and  to  make  such  investigations  as  it  deems  necessary  to  inform  itself  as  to  the
business, prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties. Each Lender and
each L/C Issuer represents and warrants that (i) the Loan Documents set forth the terms of a commercial lending facility and (ii) it is
engaged in making, acquiring or holding commercial loans in the ordinary course and is entering into this Agreement as a Lender or
L/C Issuer for the purpose of making, acquiring or holding commercial loans and providing other facilities set forth herein as may
be applicable to such Lender or L/C Issuer, and not for the purpose of purchasing, acquiring or holding any other type of financial
instrument, and each Lender and each L/C Issuer agrees not to assert a claim in contravention of the foregoing. Each Lender and
each L/C Issuer represents and warrants that it is sophisticated with respect to decisions to make, acquire and/or hold commercial
loans and to provide other facilities set forth herein, as may be applicable to such Lender or such L/C Issuer, and either it, or the

(a)        In  case  of  the  pendency  of  any  proceeding  under  any  Debtor  Relief  Law  or  any  other  judicial  proceeding
relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation
shall  then  be  due  and  payable  as  herein  expressed  or  by  declaration  or  otherwise  and  irrespective  of  whether  the
Administrative Agent shall have made any demand on the Borrowers) shall be entitled and empowered, by intervention in
such proceeding or otherwise:

(i)    to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect
of the Loans, L/C Obligations and all other Guaranteed Obligations that are owing and unpaid and to file such other

Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances
of the Lenders, the L/C Issuers and the Administrative Agent and their respective agents and counsel and all other
amounts due the Lenders, the L/C Issuers and the Administrative Agent under Sections 2.03(h) and (i), 2.09, 2.10(b)

composition  affecting  the  Guaranteed  Obligations  or  the  rights  of  any  Lender  or  any  L/C  Issuer  to  authorize  the
Administrative Agent to vote in respect of the claim of any Lender or any L/C Issuer or in any such proceeding.

Bank) and each of the L/C Issuers irrevocably authorize the Administrative Agent, at its option and in its discretion,

(i)        to  release  any  Guarantor  from  its  obligations  under  the  Guaranty  if  (A)  such  Person  ceases  to  be  a
Subsidiary or a Loan Party as a result of a transaction permitted under the Loan Documents (including pursuant to

Administrative Agent’s authority to release any Guarantor from its obligations under the Guaranty and/or any Designated
Foreign Borrower from its obligations under the Loan Documents pursuant to this Section 9.10. In each case as specified in
this Section 9.10, the Administrative Agent will promptly, at the Borrowers’ expense, execute and deliver to the applicable
Loan Party such documents as such Loan Party may reasonably request to evidence the release of such Guarantor from its
obligations under the Guaranty and/or such Designated Foreign Borrower from its obligations under the Loan Documents, in
each case, in accordance with the terms of the Loan Documents and this Section 9.10. The Administrative Agent shall have
no liability whatsoever to any Credit Party as the result of effectuating or executing any document evidencing any release of
any  Loan  Party  by  it  as  permitted  (or  which  the  Administrative  Agent  in  good  faith  believes  to  be  permitted)  by  this
Section 9.10 and any

execution  and  delivery  of  documents  pursuant  to  this  Section  9.10  shall  be  without  recourse  or  warranty  by  the
Administrative Agent.

Except as otherwise expressly set forth herein, no Cash Management Bank or Hedge Bank that obtains the benefit of the
provisions of Section 8.03 or the Guaranty by virtue of the provisions hereof shall have any right to notice of or to consent to any
amendment, waiver or modification of the provisions hereof or of the Guaranty (or to notice of or to consent to any amendment,
waiver or modification of the provisions hereof of or the Guaranty) other than in its capacity as a Lender and, in such case, only to
the extent expressly provided in the Loan Documents (it being understood that Administrative Agent may take any and all action
expressly  specified  in  Section  9.10).  Notwithstanding  any  other  provision  of  this  Article  IX  to  the  contrary,  the  Administrative
Agent  shall  not  be  required  to  verify  the  payment  of,  or  that  other  satisfactory  arrangements  have  been  made  with  respect  to,
Guaranteed Obligations arising under Guaranteed Cash Management Agreements and Guaranteed Hedge Agreements except to the
extent expressly provided herein and unless the Administrative Agent has received a Guaranteed Party Designation Notice of such
Guaranteed  Obligations,  together  with  such  supporting  documentation  as  the  Administrative  Agent  may  request,  from  the
applicable Cash Management Bank or Hedge Bank, as the case may be. The Administrative Agent shall not be required to verify

Guaranteed  Cash  Management  Agreements  and  Guaranteed  Hedge  Agreements  in  the  case  of  a  Facility  Termination  Date.  Each
Lender hereby acknowledges and agrees (including on behalf of any of its Affiliates that may be a Cash Management Bank or a
potential  Hedge  Bank)  that  (x)  obligations  of  the  Company  or  any  of  its  Subsidiaries  under  any  Guaranteed  Cash  Management
Agreement  or  Guaranteed  Hedge  Agreement  shall  be  guaranteed  pursuant  to  the  Guaranty  only  until  such  time  as  the  Guaranty

not  prohibited  by  this  Agreement  and  the  other  Loan  Documents  shall  not  require  the  consent  of  holders  of  obligations  under
Guaranteed Cash Management Agreements or Guaranteed Hedge Agreements.

Each  Guarantor  hereby  absolutely  and  unconditionally,  jointly  and  severally  guarantees,  as  primary  obligor  and  as  a
guaranty  of  payment  and  performance  and  not  merely  as  a  guaranty  of  collection,  prompt  payment  when  due,  whether  at  stated
maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of any and all Obligations
and  Additional  Obligations  (or,  if  the  scope  of  such  Guarantor’s  Guaranty  is  limited  to  a  portion  of  the  Obligations  and/or
Additional Obligations under the definition of “Guarantors”, such portion) (collectively, for each Guarantor, subject to the proviso
in  this  sentence,  its  “Guaranteed  Obligations”);  provided  that  (a)  the  Guaranteed  Obligations  of  a  Guarantor  shall  exclude  any
Excluded  Swap  Obligations  with  respect  to  such  Guarantor,  (b)  the  liability  of  each  Guarantor  individually  with  respect  to  this
Guaranty shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject
to avoidance under Section 548 of the Bankruptcy Code of the United States or any comparable provisions of any applicable state
law or other applicable Law, (c) for avoidance of doubt, the Designated Foreign Borrowers shall not be liable under this Guaranty
for any Obligations or Additional Obligations of or attributable to any U.S. Loan Party or any other Domestic Subsidiary, (d) the
guaranty given by a Guarantor which is incorporated in England and Wales does not apply to any liability to the extent that it would
result in this Guaranty constituting unlawful financial assistance within the meaning of sections 678 or 679 of the Companies Act
2006,  and  (e)  notwithstanding  anything  contrary  in  this  Section  10.1,  the  guaranty  under  this  Section  10.1  of  any  Guarantor
incorporated in Ireland does not apply to any liability to the extent that it would (A) result in this Guaranty constituting unlawful
financial assistance within the meaning of section 82 of the Companies Act 2014 of Ireland; or (B) constitute a breach of section
239  of  the  Companies  Act  2014  of  Ireland.  Without  limiting  the  generality  of  the  foregoing,  the  Guaranteed  Obligations  shall
include any such indebtedness, obligations, and liabilities with respect to Guaranteed Obligations, or portion thereof, which may be
or  hereafter  become  unenforceable  or  compromised  or  shall  be  an  allowed  or  disallowed  claim  under  any  proceeding  or  case
commenced by or against any Debtor under any Debtor Relief Laws. The Administrative Agent’s books and records showing the
amount of the Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon each Guarantor,
and conclusive for the purpose of establishing the amount of the Guaranteed Obligations absent manifest error. This Guaranty shall
not  be  affected  by  the  genuineness,  validity,  regularity  or  enforceability  of  the  Guaranteed  Obligations  or  any  instrument  or
agreement evidencing any Guaranteed Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent
of any collateral therefor, or by any fact or circumstance relating to the Guaranteed Obligations which might otherwise constitute a
defense to the obligations of the Guarantors, or any of them, under this Guaranty, and each Guarantor hereby irrevocably waives
any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing.

10.02    Rights of Lenders.

Each  Guarantor  consents  and  agrees  that  the  Credit  Parties  may,  at  any  time  and  from  time  to  time,  without  notice  or
demand,  and  without  affecting  the  enforceability  or  continuing  effectiveness  hereof:  (a)  amend,  extend,  renew,  compromise,
discharge,  accelerate  or  otherwise  change  the  time  for  payment  or  the  terms  of  the  Guaranteed  Obligations  or  any  part  thereof;
(b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this
Guaranty  or  any  Guaranteed  Obligations;  (c)  apply  such  security  and  direct  the  order  or  manner  of  sale  thereof  as  the
Administrative Agent, the L/C Issuers and the Lenders in their sole discretion may determine; and (d) release or substitute one or
more of any endorsers or other guarantors of any of the Guaranteed Obligations. Without limiting the generality of the foregoing,
each Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of
such Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of such Guarantor.

10.03    Certain Waivers.

Each Guarantor waives (a) any defense arising by reason of any disability or other defense of the Borrowers or any other
guarantor,  or  the  cessation  from  any  cause  whatsoever  (including  any  act  or  omission  of  any  Credit  Party)  of  the  liability  of  the
Borrowers  or  any  other  Loan  Party;  (b)  any  defense  based  on  any  claim  that  such  Guarantor’s  obligations  exceed  or  are  more
burdensome  than  those  of  the  Borrowers  or  any  other  Loan  Party;  (c)  the  benefit  of  any  statute  of  limitations  affecting  any
Guarantor’s liability hereunder; (d) any right to proceed against the Borrowers or any other Loan Party, proceed against or exhaust
any  security  for  the  Guaranteed  Obligations,  or  pursue  any  other  remedy  in  the  power  of  any  Credit  Party  whatsoever;  (e)  any
benefit  of  and  any  right  to  participate  in  any  security  now  or  hereafter  held  by  any  Credit  Party;  and  (f)  to  the  fullest  extent
permitted  by  law,  any  and  all  other  defenses  or  benefits  that  may  be  derived  from  or  afforded  by  applicable  Law  limiting  the
liability of or exonerating guarantors or sureties other than the occurrence of the Facility Termination Date and the payment in full
in cash (or other arrangement satisfactory to the applicable Cash Management Bank or Hedge Bank) of all Additional Obligations
to the extent then due and payable. Each Guarantor expressly waives all setoffs and counterclaims and all presentments, demands
for  payment  or  performance,  notices  of  nonpayment  or  nonperformance,  protests,  notices  of  protest,  notices  of  dishonor  and  all
other notices or demands of any kind or nature whatsoever with respect to the Guaranteed Obligations, and all notices of acceptance
of this Guaranty or of the existence, creation or incurrence of new or additional Guaranteed Obligations.

10.04    Obligations Independent.

The obligations of each Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of
the Guaranteed Obligations and the obligations of any other guarantor, and a separate action may be brought against each Guarantor
to enforce this Guaranty whether or not the Borrowers or any other person or entity is joined as a party.

10.05    Subrogation.

No Guarantor shall exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect
to any payments it makes under this Guaranty until all of the Guaranteed Obligations and any amounts payable under this Guaranty
have been indefeasibly paid and performed in full and the Revolving Commitments and the Revolving Facility are terminated. If
any amounts are paid to a Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust for the benefit
of the Credit Parties and shall forthwith be paid to the Credit Parties to reduce the amount of the Guaranteed Obligations, whether
matured or unmatured.

10.06    Termination; Reinstatement.

This Guaranty is a continuing and irrevocable guaranty of all Guaranteed Obligations now or hereafter existing and shall
remain in full force and effect until the Facility Termination Date and the payment in full in cash (or other arrangement satisfactory
to  the  applicable  Cash  Management  Bank  or  Hedge  Bank)  of  all  Additional  Obligations  to  the  extent  then  due  and  payable.
Notwithstanding  the  foregoing,  this  Guaranty  shall  continue  in  full  force  and  effect  or  be  revived,  as  the  case  may  be,  if  any
payment by or on behalf of the Borrowers or a Guarantor is made, or any of the Credit Parties exercises its right of setoff, in respect
of  the  Guaranteed  Obligations  and  such  payment  or  the  proceeds  of  such  setoff  or  any  part  thereof  is  subsequently  invalidated,
declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any of the Credit
Parties in their discretion) to be repaid to a trustee, receiver, examiner or any other party, in connection with any proceeding under
any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not
the Credit Parties are in possession of or have released this Guaranty and regardless of any prior revocation, rescission, termination
or reduction. The obligations of each Guarantor under this Section 10.06 shall survive termination of this Guaranty.

10.07    Stay of Acceleration.

If  acceleration  of  the  time  for  payment  of  any  of  the  Guaranteed  Obligations  is  stayed,  in  connection  with  any  case
commenced  by  or  against  a  Guarantor  or  the  Borrowers  under  any  Debtor  Relief  Laws,  or  otherwise,  all  such  amounts  shall
nonetheless be payable by each Guarantor, jointly and severally, immediately upon demand by the Credit Parties.

10.08    Condition of Borrowers.

Each Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from
the  Borrowers  and  any  other  guarantor  such  information  concerning  the  financial  condition,  business  and  operations  of  the
Borrowers  and  any  such  other  guarantor  as  such  Guarantor  requires,  and  that  none  of  the  Credit  Parties  has  any  duty,  and  such
Guarantor is not relying on the Credit Parties at any time, to disclose to it any information relating to the business, operations or
financial condition of the Borrowers or any other guarantor (each Guarantor waiving any duty on the part of the Credit Parties to
disclose such information and any defense relating to the failure to provide the same).

10.09    Appointment of Company.

Each of the Loan Parties hereby appoints the Company to act as its agent for all purposes of this Agreement, the other Loan
Documents and all other documents and electronic platforms entered into in connection herewith and agrees that (a) the Company
may execute such documents and provide such authorizations on behalf of such Loan Parties as the Company deems appropriate in
its sole discretion and each Loan Party shall be obligated by all of the terms of any such document and/or authorization executed on
its behalf, (b) any notice or communication delivered by the Administrative Agent, an L/C Issuer or a Lender to the Company shall
be  deemed  delivered  to  each  Loan  Party  and  (c)  the  Administrative  Agent,  the  L/C  Issuers  or  the  Lenders  may  accept,  and  be
permitted to rely on, any document, authorization, instrument or agreement executed by the Company on behalf of each of the Loan
Parties.

10.10    Right of Contribution.

The  Guarantors  agree  among  themselves  that,  in  connection  with  payments  made  hereunder,  each  Guarantor  shall  have

contribution rights against the other Guarantors as permitted under applicable Law.

10.11    Keepwell.

Each  Loan  Party  that  is  a  Qualified  ECP  Guarantor  at  the  time  the  Guaranty  or  the  grant  of  a  Lien  under  the  Loan
Documents, in each case, by any Specified Loan Party becomes effective with respect to any Swap Obligation, hereby jointly and
severally,  absolutely,  unconditionally  and  irrevocably  undertakes  to  provide  such  funds  or  other  support  to  each  Specified  Loan
Party with respect to such Swap Obligation as may be needed by such Specified Loan Party from time to time to honor all of its
obligations under the Loan Documents in respect of such Swap Obligation (but, in each case, only up to the maximum amount of
such liability that can be hereby incurred without rendering such Qualified ECP Guarantor’s obligations and undertakings under this
Article X voidable under applicable Law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount).
The obligations and undertakings of each Qualified ECP Guarantor under this Section 10.11 shall remain in full force and effect
until the Guaranteed Obligations have been indefeasibly paid and performed in full. Each Loan Party intends this Section 10.11 to
constitute, and this Section 10.11 shall be deemed to constitute, a guarantee of the obligations of, and a “keepwell, support, or other
agreement” for the benefit of, each Specified Loan Party for all purposes of the Commodity Exchange Act.

the Administrative Agent acting alone); or

(xi)    amend Section 2.16(b) to permit the designation of a Designated Foreign Borrower without the consent
of the Administrative Agent, the Lenders and the L/C Issuers to such designation, without the written consent of each

Defaulting Lender;

(B) each Lender is entitled to vote as such Lender sees fit on any bankruptcy reorganization plan that affects the Loans, and each
Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code of the United States supersedes the unanimous
consent provisions set forth herein and (C) the Required Lenders shall determine whether or not to allow a Loan Party to use cash
collateral in the context of a bankruptcy or insolvency proceeding and such determination shall be binding on all of the Lenders.

(b)    Notwithstanding anything to the contrary herein (including the other provisions of this Section 11.01) (i) the
Administrative  Agent  may,  with  the  prior  written  consent  of  the  Company  only,  amend,  modify  or  supplement  this
Agreement  or  any  of  the  other  Loan  Documents  to  cure  any  omission,  mistake,  defect  or  inconsistency,  and  (ii)  this
Agreement  may  be  amended,  amended  and  restated  or  otherwise  supplemented  or  modified  without  the  consent  of  any
Lender  (but  with  the  consent  of  Company  and  the  Administrative  Agent)  if,  upon  giving  effect  to  such  amendment,
amendment and restatement or other supplement or modification, such Lender shall no longer be a party to this Agreement
(as so amended, amended and restated or otherwise supplemented or modified), the Revolving Commitments of such Lender
shall have terminated (but such Lender shall be entitled to the benefits of the provisions of this Agreement which expressly
survive the termination of such Lender’s Revolving Commitments), such Lender shall have no other obligation to provide
additional  Credit  Extensions  to  the  Borrowers  under  this  Agreement  and  such  Lender  shall  have  been  paid  in  full  all
Obligations  (other  than  (A)  contingent  indemnification  and  expense  reimbursement  obligations  as  to  which  no  claim  has
been  asserted  and  (B)  for  the  avoidance  of  any  doubt,  any  Additional  Obligations)  owing  to  it  or  accrued  for  its  account
under this Agreement.

The  Lenders  hereby  authorize  the  Administrative  Agent  to  enter  into  amendments  to  this  Agreement  and  the  other  Loan
Documents with the Company as may be necessary or appropriate in the reasonable opinion of the Administrative Agent and the
Company in order to give effect to, and the reflect the existence of, any Incremental Revolving Facility pursuant to Section 2.18 or
any Revolving Extension Series pursuant to Section 2.19.

If any Lender does not consent to a proposed amendment, waiver, consent or release with respect to any Loan Document
that requires the consent of each Lender and that has been approved by the Required Lenders, the Company may replace such Non-
Consenting Lender in accordance with Section 11.13; provided that such amendment, waiver, consent or release can be effected as a
result of the assignment contemplated by such Section (together with all other such assignments required by the Company to be
made pursuant to this paragraph).

Person designated by a Lender on its Administrative Questionnaire then in effect for the delivery of notices that may
contain material non-public information relating to the Borrowers).

Notices  and  other  communications  sent  by  hand  or  overnight  courier  service,  or  mailed  by  certified  or  registered
mail, shall be deemed to have been given when received; notices and other communications sent by fax transmission shall
be deemed to have been given when sent (except that, if not given during normal business hours for the recipient, shall be

the  L/C  Issuers  hereunder  may  be  delivered  or  furnished  by  electronic  communication  (including  e-mail,  FPML
messaging and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent; provided
that  the  foregoing  shall  not  apply  to  notices  to  any  Lender,  the  Swingline  Lender  or  any  L/C  Issuer  pursuant  to
Article  II  if  such  Lender,  the  Swingline  Lender  or  such  L/C  Issuer,  as  applicable,  has  notified  the  Administrative
Agent that it is incapable of receiving notices under such Article II by electronic communication. The Administrative
Agent, the Swingline Lender, any L/C Issuer or the Borrowers may each, in its discretion, agree to accept notices and
other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided
that approval of such procedures may be limited to particular notices or communications.

(ii)    Unless the Administrative Agent otherwise prescribes, (A) notices and other communications sent to an

(such  as  by  the  “return  receipt  requested”  function,  as  available,  return  e-mail  or  other  written  acknowledgement)
and (B) notices and other communications posted to an Internet or intranet website shall be deemed received by the

requested”  function,  as  available,  return  e-mail  address  or  other  written  acknowledgement)  indicating  that  such
notice or communication is available and identifying the website address therefor; provided that for both clauses (A)
and (B), if such notice or other communication is not sent during the normal business hours of the recipient, such

Day for the recipient.

(c)    The Platform. THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT PARTIES
(AS  DEFINED  BELOW)  DO  NOT  WARRANT  THE  ACCURACY  OR  COMPLETENESS  OF  THE  BORROWER
MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS
IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED
OR  STATUTORY,  INCLUDING  ANY  WARRANTY  OF  MERCHANTABILITY,  FITNESS  FOR  A  PARTICULAR
PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE
DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE
PLATFORM.  In  no  event  shall  the  Administrative  Agent  or  any  of  its  Related  Parties  (collectively,  the  “Agent  Parties”)
have any liability to the Borrowers, any Lender, any L/C Issuer or any other Person for losses, claims, damages, liabilities or
expenses of any kind (whether in tort, contract or otherwise) arising out of any Loan Party’s or the Administrative Agent’s
transmission of Borrower Materials or notices through the Platform, any other electronic platform or electronic messaging
service, or through the Internet, except with respect to such losses, claims, damages, liabilities or expenses of the Borrowers
only that are determined by a court of competent jurisdiction by a final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Agent Party with respect to any such transmission of Borrower Materials
or notices through the Platform by such Agent Party.

(d)    Change of Address, Etc. Each of the Borrowers, the Administrative Agent, the L/C Issuers and the Swingline
Lender may change its address, fax number (to the extent applicable) or telephone number or e-mail address for notices and
other  communications  hereunder  by  notice  to  the  other  parties  hereto.  Each  other  Lender  may  change  its  address,  fax
number or telephone number or e-mail address for notices and other communications hereunder by notice to the Company,
the  Administrative  Agent,  the  L/C  Issuers  and  the  Swingline  Lender.  In  addition,  each  Lender  agrees  to  notify  the
Administrative  Agent  from  time  to  time  to  ensure  that  the  Administrative  Agent  has  on  record  (i)  an  effective  address,
contact name, telephone number, fax number and e-mail address to which notices and other communications may be sent
and  (ii)  accurate  wire  instructions  for  such  Lender.  Furthermore,  each  Public  Lender  agrees  to  cause  at  least  one  (1)
individual  at  or  on  behalf  of  such  Public  Lender  to  at  all  times  have  selected  the  “Private  Side  Information”  or  similar
designation  on  the  content  declaration  screen  of  the  Platform  in  order  to  enable  such  Public  Lender  or  its  delegate,  in
accordance with such

Public  Lender’s  compliance  procedures  and  applicable  Law,  including  United  States  federal  and  state  securities  Laws,  to
make  reference  to  Borrower  Materials  that  are  not  made  available  through  the  “Public  Side  Information”  portion  of  the
Platform and that may contain material non-public information with respect to the Company or its securities for purposes of
United States federal or state securities laws.

(e)    Reliance by Administrative Agent, L/C Issuers and Lenders. The Administrative Agent, the L/C Issuers and the
Lenders  shall  be  entitled  to  rely  and  act  upon  any  notices  (including,  without  limitation,  telephonic  or  electronic  notices,
Loan Notices, Letter of Credit Applications, Notice of Loan Prepayment and Swingline Loan Notices) purportedly given by
or on behalf of any Loan Party even if (i) such notices were not made in a manner specified herein, were incomplete or were
not  preceded  or  followed  by  any  other  form  of  notice  specified  herein,  or  (ii)  the  terms  thereof,  as  understood  by  the
recipient,  varied  from  any  confirmation  thereof.  The  Loan  Parties  shall  indemnify  the  Administrative  Agent,  each  L/C
Issuer, each Lender and the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the
reliance by such Person on each notice purportedly given by or on behalf of a Loan Party. All telephonic notices to and other
telephonic communications with the Administrative Agent may be recorded by the Administrative Agent, and each of the
parties hereto hereby consents to such recording.

11.03    No Waiver; Cumulative Remedies; Enforcement.

(a)    No failure by any Lender, any L/C Issuer or the Administrative Agent to exercise, and no delay by any such
Person in exercising, any right, remedy, power or privilege hereunder or under any other Loan Document shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under any other
Loan Document preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.
The rights, remedies, powers and privileges herein provided, and provided under each other Loan Document, are cumulative
and not exclusive of any rights, remedies, powers and privileges provided by law.

(b)        Notwithstanding  anything  to  the  contrary  contained  herein  or  in  any  other  Loan  Document,  the  authority  to
enforce rights and remedies hereunder and under the other Loan Documents against the Loan Parties or any of them shall be
vested  exclusively  in,  and  all  actions  and  proceedings  at  law  in  connection  with  such  enforcement  shall  be  instituted  and
maintained exclusively by, the Administrative Agent in accordance with Section 8.02 for the benefit of all the Lenders and
the L/C Issuers; provided, however, that the foregoing shall not prohibit (a) the Administrative Agent from exercising on its
own behalf the rights and remedies that inure to its benefit (solely in its capacity as Administrative Agent) hereunder and
under the other Loan Documents, (b) any L/C Issuer or the Swingline Lender from exercising the rights and remedies that
inure to its benefit (solely in its capacity as an L/C Issuer or Swingline Lender, as the case may be) hereunder and under the
other Loan Documents, (c) any Lender from

exercising setoff rights in accordance with Section 11.08 (subject to the terms of Section 2.13), or (d) any Lender from filing
proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to any Loan
Party under any Debtor Relief Law; and provided, further,  that  if  at  any  time  there  is  no  Person  acting  as  Administrative
Agent  hereunder  and  under  the  other  Loan  Documents,  then  (i)  the  Required  Lenders  shall  have  the  rights  otherwise
ascribed to the Administrative Agent pursuant to Section 8.02 and (ii) in addition to the matters set forth in clauses (b), (c)
and (d) of the preceding proviso and subject to Section 2.13, any Lender may, with the consent of the Required Lenders,
enforce any rights and remedies available to it and as authorized by the Required Lenders. Each Credit Party, whether or not
a party hereto, will be deemed, by its acceptance of the benefits of the Guarantees of the Guaranteed Obligations provided
under the Loan Documents, to have agreed to the foregoing provisions.

Administrative Agent (or any such sub-agent), each L/C Issuer, the Swingline Lender or such Related Party, as the case may

is  sought  based  on  each  Lender’s  share  of  the  Total  Revolving  Credit  Exposure  at  such  time)  of  such  unpaid  amount
(including  any  such  unpaid  amount  in  respect  of  a  claim  asserted  by  such  Lender),  such  payment  to  be  made  severally
among  them  based  on  such  Lender’s  Applicable  Percentage  (determined  as  of  the  time  that  the  applicable  unreimbursed
expense  or  indemnity  payment  is  sought),  provided  that  the  unreimbursed  expense  or  indemnified  loss,  claim,  damage,
liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such

foregoing  acting  for  the  Administrative  Agent  (or  any  such  sub-agent),  each  L/C  Issuer  or  the  Swingline  Lender  in
connection  with  such  capacity.  The  obligations  of  the  Lenders  under  this  subsection  (c)  are  subject  to  the  provisions  of
Section 2.12(d).

(d)    Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable Law, none of the parties
hereto  shall  assert,  and  each  party  hereto  hereby  waives,  and  acknowledges  that  no  other  Person  shall  have,  any  claim

damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any
other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby,
any Loan or Letter of Credit or the use of the proceeds thereof; provided, that nothing contained in this sentence shall limit
the  Loan  Parties’  indemnity  obligations  to  the  extent  set  forth  in  Section  11.04(b).  No  Indemnitee  referred  to  in
subsection (b) above shall be liable for any damages arising from the use by unintended recipients of any information or
other  materials  distributed  to  such  unintended  recipients  by  such  Indemnitee  through  telecommunications,  electronic  or
other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions
contemplated hereby or thereby.

(e)    Payments. All amounts due under this Section 11.04 shall be payable not later than ten (10) Business Days after

demand therefor. Notwithstanding anything to the

contrary herein, the Designated Foreign Borrowers shall not be required to make any payment under this Section 11.04 in
respect of any Obligations of or attributable to any U.S. Loan Party, and all other payments under this Section 11.04 shall be
made by the Administrative BorrowerCompany and/or the U.S. Loan Parties.

(f)    Survival. The agreements in this Section 11.04 and the indemnity provisions of Section 11.02(e) shall survive

termination  of  the  Aggregate  Revolving  Commitments  and  the  repayment,  satisfaction  or  discharge  of  all  the  other
Guaranteed Obligations.

11.05    Payments Set Aside.

To the extent that any payment by or on behalf of the Company is made to the Administrative Agent, any L/C Issuer or any
Lender, or the Administrative Agent, any L/C Issuer or any Lender exercises its right of setoff, and such payment or the proceeds of
such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including
pursuant to any settlement entered into by the Administrative Agent, such L/C Issuer or such Lender in its discretion) to be repaid to
a trustee, receiver, examiner or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then
(a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender and each L/C Issuer
severally  agrees  to  pay  to  the  Administrative  Agent  upon  demand  its  applicable  share  (without  duplication)  of  any  amount  so
recovered from or repaid by the Administrative Agent, plus interest thereon from the date of such demand to the date such payment
is made at a rate per annum equal to the applicable Overnight Rate from time to time in effect, in the applicable currency of such
recovery or payment. The obligations of the Lenders and the L/C Issuers under clause (b) of the preceding sentence shall survive the
payment in full of the Obligations and the termination of this Agreement.

11.06    Successors and Assigns.

(a)    Successors and Assigns Generally. The provisions of this Agreement and the other Loan Documents shall be
binding upon and inure to the benefit of the parties hereto and thereto and their respective successors and assigns permitted

way of pledge or assignment of a security interest subject to the restrictions of Section 11.06(e) (and any other attempted

construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in

Section 11.06(d) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent,
the L/C Issuers and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)    Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its
rights  and  obligations  under  this  Agreement  and  the  other  Loan  Documents  (including  all  or  a  portion  of  its  Revolving
Commitment  and  the  Loans  (including  for  purposes  of  this  subsection  (b),  participations  in  L/C  Obligations  and  in
Swingline Loans) at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i)    Minimum Amounts.

(A)        in  the  case  of  an  assignment  of  the  entire  remaining  amount  of  the  assigning  Lender’s
Revolving Commitment and/or the Loans at the time owing to it or contemporaneous assignments to related
Approved Funds (determined after giving effect to such assignments) that equal at least the amount specified
in Section 11.06(b)(i)(B) in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender

(B)        in  any  case  not  described  in  Section  11.06(b)(i)(A),  the  aggregate  amount  of  the  Revolving
Commitment  (which  for  this  purpose  includes  Loans  outstanding  thereunder)  or,  if  the  Revolving
Commitment  is  not  then  in  effect,  the  principal  outstanding  balance  of  the  Loans  of  the  assigning  Lender
subject to each such assignment, determined as of the date the Assignment and Assumption with respect to
such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment
and Assumption, as of the Trade Date, shall not be less than $5,000,000, unless each of the Administrative
Agent and, so long as no Event of Default has occurred and is continuing, the Company otherwise consents
(each such consent not to be unreasonably withheld or delayed).

(ii)    Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part
of all the assigning Lender’s rights and obligations under this Agreement and the other Loan Documents with respect
to the Loans and/or the Revolving Commitment assigned, except that this Section 11.06(b)(ii) shall not apply to the
Swingline Lender’s rights and obligations in respect of Swingline Loans.

(iii)    Required Consents. No consent shall be required for any assignment except to the extent required by

Section 11.06(b)(i)(B) and, in addition:

(A)    the consent of the Company (such consent not to be unreasonably withheld or delayed) shall be
required  unless  (1)  an  Event  of  Default  has  occurred  and  is  continuing  at  the  time  of  such  assignment  or
(2) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Company
shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to
the Administrative Agent within ten (10) Business Days after having received notice thereof;

(B)        the  consent  of  the  Administrative  Agent  (such  consent  not  to  be  unreasonably  withheld  or
delayed) shall be required for assignments in respect of any Revolving Commitment if such assignment is to
a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender;
and

(C)    the consent of the L/C Issuers and the Swingline Lender shall be required for any assignment in

respect of the Revolving Facility.

(iv)        Assignment  and  Assumption.  The  parties  to  each  assignment  shall  execute  and  deliver  to  the
Administrative Agent an Assignment and Assumption, together with a processing and recordation fee in the amount
of  $3,500;  provided,  however,  that  the  Administrative  Agent  may,  in  its  sole  discretion,  elect  to  waive  such
processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire.

(v)    No Assignment to Certain Persons. No such assignment shall be made (A) to any Borrower or any of
the Borrowers’ Affiliates or Subsidiaries, (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who,
upon  becoming  a  Lender  hereunder,  would  constitute  any  of  the  foregoing  Persons  described  in  this  clause  (B),
(C) to a natural Person (or a holding company, investment vehicle or trust for, or owned and operated for the primary
benefit of a natural person) or (D) any holder of subordinated Indebtedness.

(vi)        Certain  Additional  Payments.  In  connection  with  any  assignment  of  rights  and  obligations  of  any
Defaulting  Lender  hereunder,  no  such  assignment  shall  be  effective  unless  and  until,  in  addition  to  the  other
conditions  thereto  set  forth  herein,  the  parties  to  the  assignment  shall  make  such  additional  payments  to  the
Administrative  Agent  in  an  aggregate  amount  sufficient,  upon  distribution  thereof  as  appropriate  (which  may  be
outright  payment,  purchases  by  the  assignee  of  participations  or  subparticipations,  or  other  compensating  actions,
including funding, with the consent of the Company and the Administrative Agent, the applicable pro rata share of
Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and
assignor  hereby  irrevocably  consent),  to  (A)  pay  and  satisfy  in  full  all  payment  liabilities  then  owed  by  such
Defaulting Lender to the Administrative Agent, any L/C Issuer or

any Lender hereunder (and interest accrued thereon) and (B) acquire (and fund as appropriate) its full pro rata share
of  all  Loans  and  participations  in  Letters  of  Credit  and  Swingline  Loans  in  accordance  with  its  Applicable
Percentage.  Notwithstanding  the  foregoing,  in  the  event  that  any  assignment  of  rights  and  obligations  of  any
Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of
this  Section  11.06(b)(vi),  then  the  assignee  of  such  interest  shall  be  deemed  to  be  a  Defaulting  Lender  for  all
purposes of this Agreement until such compliance occurs.

(vii)    Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 11.06(c),
from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a
party  to  this  Agreement  and,  to  the  extent  of  the  interest  assigned  by  such  Assignment  and  Assumption,  have  the
rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of
the  interest  assigned  by  such  Assignment  and  Assumption,  be  released  from  its  obligations  under  this  Agreement
(and,  in  the  case  of  an  Assignment  and  Assumption  covering  all  of  the  assigning  Lender’s  rights  and  obligations
under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of
Sections 3.01, 3.04, 3.05 and 11.04 with respect to facts and circumstances occurring prior to the effective date of
such  assignment);  provided,  that  except  to  the  extent  otherwise  expressly  agreed  by  the  affected  parties,  no
assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising
from that Lender’s having been a Defaulting Lender. Upon request, the Borrowers (at their expense) shall execute
and deliver a Revolving Note to the assignee Lender. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this Section 11.06(b) shall be treated for purposes of this Agreement
as a sale by such Lender of a participation in such rights and obligations in accordance with Section 11.06(d).

(c)    Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrowers
(and such agency being solely for tax purposes), shall maintain at the Administrative Agent’s Office, or if the Administrative
Agent’s Office is not located in the United States, at such other office of the Administrative Agent that is located within the
United States, a copy of each Assignment and Assumption delivered to it (or the equivalent thereof in electronic form) and a
register for the recordation of the names and addresses of the Lenders, and the Revolving Commitments of, and principal
amounts  (and  stated  interest)  of  the  Loans  and  L/C  Obligations  owing  to,  each  Lender  pursuant  to  the  terms  hereof  from
time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrowers, the
Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms
hereof  as  a  Lender  hereunder  for  all  purposes  of  this  Agreement.  Any  assignment  of  any  Loans  or  other  obligations
hereunder shall be effective only upon appropriate entries with respect thereto being made in the Register.

The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to
time upon reasonable prior notice.

(d)    Participations.

(i)    Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative
Agent, sell participations to any Person (other than a natural Person, or a holding company, investment vehicle or
trust for, or owned and operated for the primary benefit of a natural Person, a Defaulting Lender or any Borrower or
any of the Borrowers’ Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights
and/or obligations under this Agreement (including all or a portion of its Revolving Commitment and/or the Loans
(including  such  Lender’s  participations  in  L/C  Obligations  and/or  Swingline  Loans)  owing  to  it);  provided  that
(i)  such  Lender’s  obligations  under  this  Agreement  shall  remain  unchanged,  (ii)  such  Lender  shall  remain  solely
responsible  to  the  other  parties  hereto  for  the  performance  of  such  obligations  and  (iii)  the  Borrowers,  the
Administrative Agent, the Lenders and the L/C Issuers shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender
shall be responsible for the indemnity under Section 11.04(c) without regard to the existence of any participations.

(ii)    Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that
such  Lender  shall  retain  the  sole  right  to  enforce  this  Agreement  and  to  approve  any  amendment,  modification  or
waiver  of  any  provision  of  this  Agreement;  provided  that  such  agreement  or  instrument  may  provide  that  such
Lender  will  not,  without  the  consent  of  the  Participant,  agree  to  any  amendment,  waiver  or  other  modification
described in the first proviso to Section 11.01 that affects such Participant. The Borrowers agree that each Participant
shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 (subject to the requirements and limitations therein,
including  the  requirements  under  Section  3.01(e),  3.01(f),  3.01(g)  and  3.01(h)  (it  being  understood  that  the
documentation required under Section 3.01(e), 3.01(f), 3.01(g) and 3.01(h) shall be delivered to the Lender who sells
the participation)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to
Section 11.06(b); provided that such Participant (A) agrees to be subject to the provisions of Sections 3.06 and 11.13
as if it were an assignee under Section 11.06(b) and (B) shall not be entitled to receive any greater payment under
Sections  3.01  or  3.04,  with  respect  to  any  participation,  than  the  Lender  from  whom  it  acquired  the  applicable
participation would have been entitled to receive, except to the extent such entitlement to receive a greater payment
results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that
sells a participation agrees, at the Borrowers’ request and expense, to use reasonable efforts to cooperate with the
Borrowers to

effectuate  the  provisions  of  Section  3.06  with  respect  to  any  Participant.  To  the  extent  permitted  by  law,  each
Participant  also  shall  be  entitled  to  the  benefits  of  Section  11.08  as  though  it  were  a  Lender;  provided  that  such
Participant  agrees  to  be  subject  to  Section  2.13  as  though  it  were  a  Lender.  Each  Lender  that  sells  a  participation
shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters
the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest
in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided  that  no  Lender
shall  have  any  obligation  to  disclose  all  or  any  portion  of  the  Participant  Register  (including  the  identity  of  any
Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its
other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to
establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103–
1(c)  of  the  United  States  Treasury  Regulations  or  to  comply  with  Section  3.01(g)  or  3.01(h).  The  entries  in  the
Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is
recorded  in  the  Participant  Register  as  the  owner  of  such  participation  for  all  purposes  of  this  Agreement
notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as
Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e)    Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its
rights under this Agreement (including under its Revolving Note or Revolving Notes, if any) to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge
or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for
such Lender as a party hereto.

(f)        Resignation  as  L/C  Issuer  or  Swingline  Lender  after  Assignment.  Notwithstanding  anything  to  the  contrary
contained herein, if at any time Bank of America assigns all of its Revolving Commitment and Revolving Loans pursuant to
Section 11.06(b), Bank of America may, (i) upon thirty (30) days’ notice to the Company and the Lenders, resign as L/C
Issuer  and/or  (ii)  upon  thirty  (30)  days’  notice  to  the  Company,  resign  as  Swingline  Lender.  In  the  event  of  any  such
resignation  as  L/C  Issuer  or  Swingline  Lender,  the  Company  shall  be  entitled  to  appoint  from  among  the  Lenders  a
successor  L/C  Issuer  or  Swingline  Lender  hereunder;  provided, however,  that  no  failure  by  the  Company  to  appoint  any
such successor shall affect the resignation of Bank of America as L/C Issuer or Swingline Lender, as the case may be. If
Bank of America resigns as L/C Issuer, it shall retain all the rights, powers, privileges and duties of the L/C Issuer hereunder
with  respect  to  all  Letters  of  Credit  outstanding  as  of  the  effective  date  of  its  resignation  as  L/C  Issuer  and  all  L/C
Obligations  with  respect  thereto  (including  the  right  to  require  the  Lenders  to  make  Base  Rate  Loans  or  fund  risk
participations in

Unreimbursed Amounts pursuant to Section 2.03(c)). If Bank of America resigns as Swingline Lender, it shall retain all the
rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the
effective  date  of  such  resignation,  including  the  right  to  require  the  Lenders  to  make  Base  Rate  Loans  or  fund  risk
participations in outstanding Swingline Loans pursuant to Section 2.04(c). Upon the appointment of a successor L/C Issuer
and/or Swingline Lender, (A) such successor shall succeed to and become vested with all of the rights, powers, privileges
and duties of the retiring L/C Issuer or Swingline Lender, as the case may be, and (B) the successor L/C Issuer shall issue
letters  of  credit  in  substitution  for  the  Letters  of  Credit,  if  any,  outstanding  at  the  time  of  such  succession  or  make  other
arrangements satisfactory to Bank of America to effectively assume the obligations of Bank of America with respect to such
Letters of Credit.

(g)    [Reserved].

(h)    Disqualified Institutions.

(i)    No assignment shall be made to any Person that was a Disqualified Institution as of the “Trade Date” on
which  the  applicable  Lender  entered  into  a  binding  agreement  to  sell  and  assign  all  or  a  portion  of  its  rights  and
obligations  under  this  Agreement  to  such  Person  (unless  the  Company  has  consented  to  such  assignment  as
otherwise  contemplated  by  this  Section  11.06,  in  which  case  such  Person  will  not  be  considered  a  Disqualified
Institution  for  the  purpose  of  such  assignment).  For  the  avoidance  of  doubt,  with  respect  to  any  assignee  that
becomes a Disqualified Institution after the applicable Trade Date (including as a result of the delivery of a notice
pursuant to, and/or the expiration of the notice period referred to in, the definition of “Disqualified Institution”), such
assignee shall not retroactively be considered a Disqualified Institution. Any assignment in violation of this Section
11.06(h)(i) shall not be void, but the other provisions of this Section 11.06(h) shall apply.

(ii)        If  any  assignment  is  made  to  any  Disqualified  Institution  without  the  Company’s  prior  consent  in
violation of Section 11.06(h)(i), the Borrowers may, at their effort and the sole expense of the assigning institution,
upon  notice  to  the  applicable  Disqualified  Institution  and  the  Administrative  Agent,  (A)  terminate  any  Revolving
Commitment of such Disqualified Institution and repay all obligations of the Borrowers owing to such Disqualified
Institution in connection with such Revolving Commitment, and/or (B) require such Disqualified Institution to assign
and delegate, without recourse (in accordance with and subject to the restrictions contained in this Section 11.06), all
of its interest, rights and obligations under this Agreement and related Loan Documents to an Eligible Assignee that
shall  assume  such  obligations  at  the  lesser  of  (x)  the  principal  amount  thereof  and  (y)  the  amount  that  such
Disqualified  Institution  paid  to  acquire  such  interests,  rights  and  obligations,  in  each  case  plus  accrued  interest,
accrued fees and all other amounts (other than principal amounts)

payable to it hereunder and other the other Loan Documents; provided that such assignment does not conflict with
applicable Laws.

(iii)        Notwithstanding  anything  to  the  contrary  contained  in  this  Agreement,  Disqualified  Institutions
(A) will not (x) have the right to receive information, reports or other materials provided to Lenders by the Company,
the Administrative Agent or any other Lender, (y) attend or participate in meetings attended by the Lenders and the
Administrative Agent, or (z) access any electronic site established for the Lenders or confidential communications
from  counsel  to  or  financial  advisors  of  the  Administrative  Agent  or  the  Lenders  and  (B)  (x)  for  purposes  of  any
consent to any amendment, waiver or modification of, or any action under, and for the purpose of any direction to the
Administrative  Agent  or  any  Lender  to  undertake  any  action  (or  refrain  from  taking  any  action)  under  this
Agreement or any other Loan Document, each Disqualified Institution will be deemed to have consented in the same
proportion  as  the  Lenders  that  are  not  Disqualified  Institutions  consented  to  such  matter  and  (y)  for  purposes  of
voting  on  any  plan  of  reorganization  or  plan  of  liquidation  pursuant  to  any  Debtor  Relief  Laws  (“Plan  of
Reorganization”),  each  Disqualified  Institution  party  hereto  hereby  agrees  (1)  not  to  vote  on  such  Plan  of
Reorganization,  (2)  if  such  Disqualified  Institution  does  vote  on  such  Plan  of  Reorganization  notwithstanding  the
restriction in the foregoing clause (1), such vote will be deemed not to be in good faith and shall be “designated”
pursuant to Section 1126(e) of the Bankruptcy Code (or any similar provision in any other Debtor Relief Laws), and
such  vote  shall  not  be  counted  in  determining  whether  the  applicable  class  has  accepted  or  rejected  such  Plan  of
Reorganization in accordance with Section 1126(c) of the Bankruptcy Code (or any similar provision in any other
Debtor Relief Laws) and (3) not to contest any request by any party for a determination by the Bankruptcy Court (or
other applicable court of competent jurisdiction) effectuating the foregoing clause (2).

(iv)        The  Administrative  Agent  shall,  and  the  Borrowers  hereby  expressly  authorize  the  Administrative
Agent, to (A) post the list of Disqualified Institutions provided by the Company and any updates thereto from time to
time  (collectively,  the  “DQ  List”)  on  the  Platform,  including  that  portion  of  the  Platform  that  is  designated  for
“public side” Lenders or (B) provide the DQ List to each Lender requesting the same.

11.07    Treatment of Certain Information; Confidentiality.

(a)    Treatment of Certain Information. Each of the Administrative Agent, the Lenders and the L/C Issuers agrees to
maintain  the  confidentiality  of  the  Information  (as  defined  below),  except  that  Information  may  be  disclosed  (i)  to  its
Affiliates,  auditors  and  its  Related  Parties  (it  being  understood  that  the  Persons  to  whom  such  disclosure  is  made  will  be
informed  of  the  confidential  nature  of  such  Information  and  instructed  to  keep  such  Information  confidential),  (ii)  to  the
extent required or requested by any regulatory

authority  purporting  to  have  jurisdiction  over  such  Person  or  its  Related  Parties  (including  any  self-regulatory  authority,
such as the National Association of Insurance Commissioners) (in which case, such Person agrees to inform the Company
promptly thereof prior to such disclosure unless (x) such Person is prohibited from doing so under applicable Law or (y)
such  disclosure  is  pursuant  to  a  regulatory  audit  or  exam  conducted  by  bank  accountants  or  any  governmental  bank
regulatory  authority  exercising  examination  or  regulatory  authority),  (iii)  to  the  extent  required  by  applicable  Laws  or
regulations or by any subpoena or similar legal process (in which case, such Person agrees to inform the Company promptly
thereof prior to such disclosure unless such Person is prohibited from doing so under applicable Law), (iv) to any other party
hereto, (v) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or
proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder,
(vi) subject to an agreement containing provisions substantially the same as those of this Section 11.07, to (A) any assignee
of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement or
any Eligible Assignee invited to be a Lender pursuant to Section 2.18 or Section 11.01 or (B) any actual or prospective party
(or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the
Borrowers  and  their  obligations,  this  Agreement  or  payments  hereunder  (it  being  understood  that  the  DQ  List  may  be
disclosed  to  any  assignee,  or  prospective  assignee,  in  reliance  on  this  clause  (vi)),  (vii)  on  a  confidential  basis  to  (A)  the
provider of any Platform or other electronic delivery service used by the Administrative Agent, any L/C Issuer and/or the
Swingline Lender to deliver Borrower Materials or notices to the Lenders or (B) the CUSIP Service Bureau or any similar
agency in connection with the issuance and monitoring of CUSIP numbers or other market identifiers with respect to the
credit facilities provided hereunder, or (viii) with the consent of the Company or to the extent such Information (1) becomes
publicly  available  other  than  as  a  result  of  a  breach  of  this  Section  11.07  or  (2)  becomes  available  to  the  Administrative
Agent, any Lender, any L/C Issuer or any of their respective Affiliates on a nonconfidential basis from a source other than
the Borrowers, their Subsidiaries or their attorneys or accountants. For purposes of this Section 11.07, “Information” means
all  information  received  from  the  Company  or  any  Subsidiary  relating  to  the  Company  or  any  Subsidiary  or  any  of  their
respective businesses, other than any such information that is available to the Administrative Agent, any Lender or any L/C
Issuer  on  a  nonconfidential  basis  prior  to  disclosure  by  the  Company  or  any  Subsidiary,;  provided  that,  in  the  case  of
information received from the Company or any Subsidiary after the date hereof, such information is clearly identified at the
time  of  delivery  as  confidential.  Any  Person  required  to  maintain  the  confidentiality  of  Information  as  provided  in  this
Section 11.07 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree
of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.
In addition, the Administrative Agent and the Lenders may disclose the existence of this Agreement and information about
this Agreement to market data collectors, similar service providers to the lending industry and service providers to

the  Administrative  Agent  and  the  Lenders  in  connection  with  the  administration  of  this  Agreement,  the  other  Loan
Documents and the Revolving Commitments.

(b)    Non-Public Information. Each of the Administrative Agent, the Lenders and the L/C Issuers acknowledges that
(i) the Information may include material non-public information concerning a Loan Party or a Subsidiary, as the case may
be, (ii) it has developed compliance procedures regarding the use of material non-public information and (iii) it will handle
such material non-public information in accordance with applicable Law, including United States federal and state securities
Laws.

11.08    Right of Setoff.

If  an  Event  of  Default  shall  have  occurred  and  be  continuing,  each  Lender,  each  L/C  Issuer  and  each  of  their  respective
Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and
apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other
obligations (in whatever currency) at any time owing by such Lender, such L/C Issuer or any such Affiliate to or for the credit or the
account of the Company or any other Loan Party against any and all of the obligations of the Company or such Loan Party now or
hereafter  existing  under  this  Agreement  or  any  other  Loan  Document  to  such  Lender  or  such  L/C  Issuer  or  their  respective
Affiliates,  irrespective  of  whether  or  not  such  Lender,  such  L/C  Issuer  or  Affiliate  shall  have  made  any  demand  under  this
Agreement or any other Loan Document and although such obligations of the Company or such Loan Party may be contingent or
unmatured, secured or unsecured, or are owed to a branch, office or Affiliate of such Lender or such L/C Issuer different from the
branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting
Lender shall exercise any such right of setoff, (a) all amounts so set off shall be paid over immediately to the Administrative Agent
for further application in accordance with the provisions of Section 2.15 and, pending such payment, shall be segregated by such
Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the L/C Issuers and the
Lenders,  and  (b)  the  Defaulting  Lender  shall  provide  promptly  to  the  Administrative  Agent  a  statement  describing  in  reasonable
detail the Guaranteed Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each
Lender,  each  L/C  Issuer  and  their  respective  Affiliates  under  this  Section  11.08  are  in  addition  to  other  rights  and  remedies
(including other rights of setoff) that such Lender, such L/C Issuer or their respective Affiliates may have. Each Lender and each
L/C Issuer agrees to notify the Company and the Administrative Agent promptly after any such setoff and application, provided that
the  failure  to  give  such  notice  shall  not  affect  the  validity  of  such  setoff  and  application.  Notwithstanding  the  provisions  of  this
Section 11.08, if at any time any Lender, any L/C Issuer or any of their respective Affiliates maintains one or more deposit accounts
for the Company or any other Loan Party into which Medicare and/or Medicaid receivables are deposited, such Person shall waive
the right of setoff set forth herein.

11.09    Interest Rate Limitation.

Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or agreed to be paid under the
Loan Documents shall not exceed the maximum rate of non-usurious interest permitted by applicable Law (the “Maximum Rate”).
If the Administrative Agent or any Lender shall receive interest in an amount that exceeds the Maximum Rate, the excess interest
shall  be  applied  to  the  principal  of  the  Loans  or,  if  it  exceeds  such  unpaid  principal,  refunded  to  the  Borrowers.  In  determining
whether the interest contracted for, charged, or received by the Administrative Agent or a Lender exceeds the Maximum Rate, such
Person  may,  to  the  extent  permitted  by  applicable  Law,  (a)  characterize  any  payment  that  is  not  principal  as  an  expense,  fee,  or
premium  rather  than  interest,  (b)  exclude  voluntary  prepayments  and  the  effects  thereof,  and  (c)  amortize,  prorate,  allocate,  and
spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Obligations hereunder.

11.10    Counterparts; Integration; Effectiveness.

This Agreement and each of the other Loan Documents may be executed in counterparts (and by different parties hereto in
different  counterparts),  each  of  which  shall  constitute  an  original,  but  all  of  which  when  taken  together  shall  constitute  a  single
contract.  This  Agreement,  the  other  Loan  Documents,  and  any  separate  letter  agreements  with  respect  to  fees  payable  to  the
Administrative Agent or any L/C Issuer, constitute the entire contract among the parties relating to the subject matter hereof and
supersede  any  and  all  previous  agreements  and  understandings,  oral  or  written,  relating  to  the  subject  matter  hereof.  Except  as
provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and
when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the
other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement or any other Loan Document, or any
certificate delivered thereunder, by fax transmission or e-mail transmission (e.g., “pdf” or “tif”) shall be effective as delivery of a
manually executed counterpart of this Agreement or such other Loan Document or certificate. Without limiting the foregoing, to the
extent a manually executed counterpart is not specifically required to be delivered under the terms of any Loan Document, upon the
request  of  any  party,  such  fax  transmission  or  e-mail  transmission  shall  be  promptly  followed  by  such  manually  executed
counterpart.

11.11    Survival of Representations and Warranties.

All representations and warranties made hereunder and in any other Loan Document or other document delivered pursuant
hereto  or  thereto  or  in  connection  herewith  or  therewith  shall  survive  the  execution  and  delivery  hereof  and  thereof.  Such
representations and warranties have been or will be relied upon by the Administrative Agent and each Lender, regardless of any
investigation made by the Administrative Agent or any Lender or on their behalf and notwithstanding that the Administrative Agent
or any Lender may have had notice or knowledge of any Default at the time of any Credit Extension, and shall continue in full force
and effect as long as any Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any Letter of Credit shall
remain outstanding.

11.12    Severability.

If  any  provision  of  this  Agreement  or  the  other  Loan  Documents  is  held  to  be  illegal,  invalid  or  unenforceable,  (a)  the
legality,  validity  and  enforceability  of  the  remaining  provisions  of  this  Agreement  and  the  other  Loan  Documents  shall  not  be
affected  or  impaired  thereby  and  (b)  the  parties  shall  endeavor  in  good  faith  negotiations  to  replace  the  illegal,  invalid  or
unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid
or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 11.12, if and to the extent that the
enforceability  of  any  provisions  in  this  Agreement  relating  to  Defaulting  Lenders  shall  be  limited  by  Debtor  Relief  Laws,  as
determined in good faith by the Administrative Agent, the L/C Issuers or the Swingline Lender, as applicable, then such provisions
shall be deemed to be in effect only to the extent not so limited.

11.13    Replacement of Lenders.

(a)    If the Company is entitled to replace a Lender pursuant to the provisions of Section 3.06, or if any Lender is a
Defaulting Lender or a Non-Consenting Lender or if any other circumstance exists hereunder that gives the Company the
right to replace a Lender as a party hereto, then the Company may, at its sole expense and effort, upon notice to such Lender
and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject
to the restrictions contained in, and consents required by, Section 11.06), all of its interests, rights (other than its existing
rights  to  payments  pursuant  to  Sections  3.01  and  3.04)  and  obligations  under  this  Agreement  and  the  related  Loan
Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment), provided that:

(i)    the Company shall have paid (or caused a Designated Foreign Borrower to pay) to the Administrative

Agent the assignment fee (if any) specified in Section 11.06(b);

(ii)    such Lender shall have received payment of an amount equal to 100% of the outstanding principal of its
Loans and L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and
under the other Loan Documents (including any amounts under Section 3.05) from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or the Company or applicable Designated Foreign Borrower (in
the case of all other amounts);

(iii)        in  the  case  of  any  such  assignment  resulting  from  a  claim  for  compensation  under  Section  3.04  or
payments  required  to  be  made  pursuant  to  Section  3.01,  such  assignment  will  result  in  a  reduction  in  such
compensation or payments thereafter;

(iv)    such assignment does not conflict with applicable Laws; and

(v)    in the case of an assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable

assignee shall have consented to the applicable amendment, waiver or consent.

(b)       A  Lender  shall  not  be  required  to  make  any  such  assignment  or  delegation  if,  prior  thereto,  as  a  result  of  a
waiver  by  such  Lender  or  otherwise,  the  circumstances  entitling  the  Company  to  require  such  assignment  and  delegation
cease to apply. Each Lender agrees that, if the Company elects to replace such Lender in accordance with this Section 11.13,
it shall (subject to the Company’s compliance with the provisions of this Section 11.13) promptly execute and deliver to the
Administrative  Agent  an  Assignment  and  Assumption  to  evidence  the  assignment  and  shall  deliver  to  the  Administrative
Agent  any  Revolving  Note  (if  Revolving  Notes  have  been  issued  in  respect  of  such  Lender’s  Loans  and/or  Revolving
Commitments)  subject  to  such  Assignment  and  Assumption;  provided  that  the  failure  of  any  such  Lender  to  execute  an
Assignment and Assumption shall not render such assignment invalid and such assignment shall be recorded in the Register.

waiver or other modification hereof or of any other Loan Document), the Company and each other Loan Party acknowledges and
agrees,  and  acknowledges  its  Affiliates’  understanding,  that:  (a)  (i)  the  arranging  and  other  services  regarding  this  Agreement
provided  by  the  Administrative  Agent  and  any  Affiliate  thereof,  the  Arrangers  and  the  Lenders  are  arm’s-length  commercial

Company and the other Loan Parties has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed
appropriate, and (iii) the Company and each other Loan Party is capable of evaluating, and understands and accepts, the terms, risks
and conditions of the transactions contemplated hereby and by the other Loan Documents; (b) (i) the Administrative Agent and its
Affiliates (including any Affiliate that is an Arranger) and each Lender each is and has been acting solely as a principal and, except

other Loan Party or any of their respective Affiliates with respect to the transactions contemplated hereby except those obligations
expressly  set  forth  herein  and  in  the  other  Loan  Documents;  and  (c)  the  Administrative  Agent  and  its  Affiliates  (including  any

those  of  the  Company,  the  other  Loan  Parties  and  their  respective  Affiliates,  and  neither  the  Administrative  Agent,  any  of  its
Affiliates  (including  any  Affiliate  that  is  an  Arranger)  nor  any  Lender  has  any  obligation  to  disclose  any  of  such  interests  to  the

hereby notifies the Company and the other Loan Parties that pursuant to the requirements of the USA PATRIOT Act (Title III of
Pub. L. 107–56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that

Company and each other Loan Party in accordance with the Patriot Act. The Company and each other Loan Party shall, promptly
following  a  request  by  the  Administrative  Agent  or  any  Lender,  provide  all  such  other  documentation  and  information  that  the

Agreement and notwithstanding anything to the contrary in

any  Loan  Document  or  in  any  other  agreement,  arrangement  or  understanding  among  any  such  parties,  each  party  hereto
acknowledges that any liability of any Lender or any L/C Issuer that is an EEAAffected Financial Institution arising under any Loan
Document,  to  the  extent  such  liability  is  unsecured,  may  be  subject  to  the  write-down  and  conversion  powers  of  an  EEAWrite-
Down and Conversion Powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to
be bound by:

(a)    the application of any Write-Down and Conversion Powers by an EEAthe applicable Resolution Authority to

(b)    the effects of any Bail-In Action on any such liability, including, if applicable:

(i)    a reduction in full or in part or cancellation of any such liability;

conversion powers of any EEAWrite-Down and Conversion Powers of the applicable Resolution Authority.

11.21    Acknowledgement Regarding Any Supported QFCs.

To  the  extent  that  the  Loan  Documents  provide  support,  through  a  guarantee  or  otherwise,  for  any  Swap  Contract  or  any
other agreement or instrument that is a QFC (such support, “QFC Credit Support”, and each such QFC, a “Supported QFC”),  the
parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under
the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with
the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit
Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be
stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): In
the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S.
Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and
obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC
or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under
the U.S. Special Resolution Regime if the Supported QFC and

such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States
or  a  state  of  the  United  States.  In  the  event  a  Covered  Party  or  a  BHC  Act  Affiliate  of  a  Covered  Party  becomes  subject  to  a
proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such
Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no
greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the
Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing,
it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the
rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

11.22    [Reserved].

11.23    Judgment Currency.

If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or any other Loan
Document  in  one  currency  into  another  currency,  the  rate  of  exchange  used  shall  be  that  at  which  in  accordance  with  normal
banking  procedures  the  Administrative  Agent  could  purchase  the  first  currency  with  such  other  currency  on  the  Business  Day
preceding that on which final judgment is given. The obligation of each Loan Party in respect of any such sum due from it to the
Administrative  Agent  or  any  Lender  hereunder  or  under  the  other  Loan  Documents  shall,  notwithstanding  any  judgment  in  a
currency (the “Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions
of this Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the
Administrative  Agent  or  such  Lender,  as  the  case  may  be,  of  any  sum  adjudged  to  be  so  due  in  the  Judgment  Currency,  the
Administrative  Agent  or  such  Lender,  as  the  case  may  be,  may  in  accordance  with  normal  banking  procedures  purchase  the
Agreement  Currency  with  the  Judgment  Currency.  If  the  amount  of  the  Agreement  Currency  so  purchased  is  less  than  the  sum
originally due to the Administrative Agent or any Lender from any Loan Party in the Agreement Currency, such Loan Party agrees,
as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent or such Lender, as the case
may  be,  against  such  loss.  If  the  amount  of  the  Agreement  Currency  so  purchased  is  greater  than  the  sum  originally  due  to  the
Administrative Agent or any Lender in such currency, the Administrative Agent or such Lender, as the case may be, agrees to return
the amount of any excess to such Loan Party (or to any other Person who may be entitled thereto under applicable Law).

11.24    ENTIRE AGREEMENT.

THIS  AGREEMENT  AND  THE  OTHER  LOAN  DOCUMENTS  REPRESENT  THE  FINAL  AGREEMENT
AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS
AMONG THE PARTIES.
