ADDITIONAL DISCLOSURE

Certifications and Disclosure Regarding Controls and Procedures.

(a) 

Certifications. 

See Exhibits 99.4, 99.5, 99.6 and 99.7 to this Annual Report on Form 40-F.

(b) 

Disclosure Controls and Procedures. 

As of the end of Trillium Therapeutics Inc.'s ("Trillium" or the "Company") fiscal year ended December 31, 2019, an evaluation of the effectiveness of
Trillium's "disclosure controls and procedures" (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as
amended  (the  "Exchange  Act"))  was  carried  out  by  the  management  of  Trillium,  with  the  participation  of  the  President  and  Chief  Executive  Officer
("CEO") and the Chief Financial Officer ("CFO") of Trillium.  Based upon that evaluation, the CEO and CFO have concluded that as of the end of that
fiscal year, Trillium's disclosure controls and procedures were effective to ensure that information required to be disclosed by Trillium in reports that it
files or submits under the Exchange Act, is (i) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange
Commission (the "Commission") rules and forms and (ii) accumulated and communicated to the management of Trillium, including the CEO and CFO, to
allow timely decisions regarding required disclosure.

It should be noted that while the CEO and CFO believe that Trillium's disclosure controls and procedures provide a reasonable level of assurance that they
are effective, they do not expect that Trillium's disclosure controls and procedures or internal control over financial reporting will prevent all errors and
fraud.  A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control
system are met.

(c) 

Management's Annual Report on Internal Control Over Financial Reporting. 

Management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  Trillium's  financial  reporting.    Trillium's  internal  control
system was designed to provide reasonable assurance that all transactions are accurately recorded, that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that Trillium's assets are safeguarded.

Management  has  assessed  the  effectiveness  of  Trillium's  internal  control  over  financial  reporting  as  at  December  31,  2019.   In  making  its  assessment,
management  used  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  ("COSO")  framework  in  Internal  Control  -  Integrated
Framework  (2013)  to  evaluate  the  effectiveness  of  Trillium's  internal  control  over  financial  reporting.    Based  on  this  assessment,  management  has
concluded that Trillium's internal control over financial reporting was effective as of December 31, 2019.

US-2

(d) 

Attestation Report of the Registered Public Accounting Firm. 

This annual report does not include an attestation report of the Company's independent registered public accounting firm regarding internal control over
financial  reporting  because  emerging  growth  companies  are  exempt  from  this  requirement  for  so  long  as  they  remain  emerging  growth  companies. 
Therefore, management's report on internal control over financial reporting is not subject to attestation by the Company's independent registered public
accounting firm.

(e) 

Changes in Internal Control Over Financial Reporting.  The required disclosure is included under the heading "Disclosure Controls and Internal Controls
Over Financial Reporting" in Trillium's Management's Discussion and Analysis for the years ended December 31, 2019 and 2018, filed as Exhibit 99.2 to
this Annual Report on Form 40-F.

Notices Pursuant to Regulation BTR. 

None. 

Audit Committee Financial Expert.

Trillium's board of directors has determined that Luke Beshar, a member of Trillium's audit committee, qualifies as an "audit committee financial expert" (as such
term is defined in paragraph (8) of General Instruction B to Form 40-F) and is "independent" as that term is defined in the rules of the Nasdaq Stock Market.

Code of Business Conduct and Ethics.

Trillium has adopted a Code of Business Conduct and Ethics, which qualifies as a "code as ethics" (as such term is defined in paragraph (9) of General Instruction
B  to  Form  40-F),  that  is  applicable  to  each  of  Trillium's  directors,  officers  and  employees,  including  its  principal  executive  officer,  principal  financial  officer,
principal accounting officer or controller and persons performing similar functions.

The Code of Business Conduct and Ethics is available for viewing on Trillium's website at www.trilliumtherapeutics.com, and is available in print, without charge,
to any shareholder who requests a copy of it.  Requests for copies of the Code of Business Conduct and Ethics should be made by contacting: James Parsons, Chief
Financial Officer, by phone at (416) 595-0627 or by e-mail to info@trilliumtherapeutics.com.

Since the date on which Trillium became subject to the reporting requirements of Section 13(a) or 15(d) of the Exchange Act, there have not been any amendments
to, or waivers, including implicit waivers, granted from, any provision of the Code of Business Conduct and Ethics.

US-3

If any amendment to the Code of Business Conduct and Ethics is made, or if any waiver from the provisions thereof is granted, Trillium may elect to disclose the
information  about  such  amendment  or  waiver  required  by  Form  40-F  to  be  disclosed,  by  posting  such  disclosure  on  its  website,  which  may  be  accessed  at
www.trilliumtherapeutics.com.

Principal Accountant Fees and Services.

The  required  disclosure  is  included  under  the  heading  "Audit  Committee  Information  -  External  Auditors  Service  Fees  (By  Category)"  in  Trillium's  Annual
Information Form for the year ended December 31, 2019, filed as Exhibit 99.1 to this Annual Report on Form 40-F.

Pre-Approval Policies and Procedures.

(a) 

The audit committee of Trillium's board of directors has adopted an Auditor Services Pre-Approval Policy (the "Policy") with respect to the pre-approval
of  audit  and  permitted  non-audit  services  to  be  provided  by  Ernst  &  Young  LLP,  Trillium's  independent  auditor.    Pursuant  to  the  Policy,  the  audit
committee on an annual basis may approve the provision of a specified list of audit and permitted non-audit services that the audit committee believes to
be typical, reoccurring or otherwise likely to be provided by the external auditor during the then current fiscal year. All pre-approvals granted under this
Policy shall be sufficiently detailed as to the particular services being provided that it will not be necessary for management of Trillium to exercise any
discretion in determining whether a particular service has been pre-approved.

In addition, pursuant to the Policy the audit committee has delegated its pre-approval authority to the Chair of the audit committee for services where the
aggregate  fees  are  estimated  to  be  less  than  or  equal  to  Cdn.  $50,000.    The  Chair  of  the  audit  committee  is  required  to  report  any  such  granted  pre-
approvals  to  the  audit  committee  at  its  next  scheduled  meeting.    The  audit  committee  shall  not  delegate  to  management  the  audit  committee's
responsibilities for pre-approving audit and non-audit services to be performed by the external auditor.

Pursuant  to  the  Policy,  there  is  an  exception  to  the  pre-approval  requirements  for  permitted  non-audit  services,  provided  all  such  services  were  not
recognized at the time of the engagement to be non-audit services and, once recognized, are promptly brought to the attention of the audit committee and
approved prior to the completion of the audit.  The aggregate amount of all services approved in this manner may not constitute more than five percent of
the total fees paid to the external auditor during the fiscal year in which the services are provided.

(b) 

Of the fees reported in this Annual Report on Form 40-F under the heading "Principal Accountant Fees and Services", none of the fees billed by Ernst &
Young  LLP  were  approved  by  Trillium's  audit  committee  pursuant  to  the  de  minimus exception  provided  by  Section  (c)(7)(i)(C)  of  Rule  2-01  of
Regulation S-X.

Off-Balance Sheet Arrangements.

Trillium does not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on its financial condition, revenues
or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

US-5

Tabular Disclosure of Contractual Obligations.

years ended December 31, 2019 and 2018, filed as Exhibit 99.2 to this Annual Report on Form 40-F.

Identification of the Audit Committee.

Trillium has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act.  The members of the audit
committee are:  Luke Beshar, Thomas Reynolds and Helen Tayton-Martin.

Mine Safety Disclosure.

however, that such a company shall comply with the Notification of Material Noncompliance requirement (Rule 5625), the Voting Rights requirement (Rule 5640),

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Annual Information Form, or AIF, contains forward-looking statements within the meaning of applicable securities laws. All statements contained herein that
are  not  clearly  historical  in  nature  are  forward-looking,  and  the  words  "anticipate",  "believe",  "expect",  "estimate",  "may",  "will",  "could",  "leading",  "intend",
"contemplate", "shall" and similar expressions are generally intended to identify forward-looking statements. Forward-looking statements in this AIF include, but
are not limited to, statements with respect to:

our expected future loss and accumulated deficit levels;
our projected financial position and estimated cash burn rate;
our requirements for, and the ability to obtain, future funding on favorable terms or at all;
our projections for the SIRPαFc development plans and progress of each of our products and technologies, particularly with respect to the timely and
successful completion of studies and trials and availability of results from such studies and trials;
our plans to focus development of TTI-621 on patients with hematological malignancies, such as peripheral T-cell lymphoma, cutaneous T-cell
lymphoma, and acute myeloid leukemia, based on our early clinical results;
our expectations about our products' safety and efficacy;
our expectations regarding our ability to arrange for and scale up the manufacturing of our products and technologies;
our expectations regarding the progress, and the successful and timely completion, of the various stages of the regulatory approval process;
our expectations about the timing of achieving milestones and the cost of our development programs;
our observations and expectations regarding the relative low binding of SIRPαFc to red blood cells, or RBCs, compared to anti-CD47 monoclonal
antibodies and proprietary CD47-blocking agents and the potential benefits to patients;
our ability to intensify the dose of TTI-621 with the goal of achieving increased blockade of CD47;
our expectation that we will achieve levels of TTI-622 in patients sufficient to obtain sustained CD47 blockade;
our expectation that TTI-622 is likely to be more effective in combination with agents that provide additional "eat" signals to macrophages or other forms
of immune activation;
our plans to market, sell and distribute our products and technologies;
our expectations regarding the acceptance of our products and technologies by the market;
our expectations about our STING agonist program and our ability to secure a strategic partnership to develop this program further;
our ability to retain and access appropriate staff, management and expert advisers;
our ability to secure strategic partnerships with larger pharmaceutical and biotechnology companies;
our expectations with respect to existing and future corporate alliances and licensing transactions with third parties, and the receipt and timing of any
payments to be made by us or to us in respect of such arrangements; and
our strategy with respect to the protection of our intellectual property.

All forward-looking statements reflect our beliefs and assumptions based on information available at the time the assumption was made. These forward-looking
statements are not based on historical facts but rather on management's expectations regarding future activities, results of operations, performance, future capital
and other expenditures (including the amount, nature and sources of funding thereof), competitive advantages, business prospects and opportunities.

By its nature, forward-looking information involves numerous assumptions, inherent risks and uncertainties, both general and specific, known and unknown, that
contribute to the possibility that the predictions, forecasts, projections or other forward-looking statements will not occur. In evaluating forward-looking statements,
readers should specifically consider various factors, including the risks outlined under the heading "Risk Factors" in this AIF. Some of these risks and assumptions
include, among others:

3

 
substantial fluctuation of losses from quarter to quarter and year to year due to numerous external risk factors, and anticipation that we will continue to
incur significant losses in the future;
uncertainty as to our ability to raise additional funding to support operations;
our ability to generate product revenue to maintain our operations without additional funding;
the risks associated with the development of our product candidates which are at early stages of development;
positive results from preclinical and early clinical research are not necessarily predictive of the results of later-stage clinical trials;
reliance on third parties to plan, conduct and monitor our preclinical studies and clinical trials;
our product candidates may fail to demonstrate safety and efficacy to the satisfaction of regulatory authorities or may not otherwise produce positive
results;
risks related to filing Investigational New Drug applications, or INDs, to commence clinical trials and to continue clinical trials if approved;
the risks of delays and inability to complete clinical trials due to difficulties enrolling patients;
the risk that we may not achieve our publicly announced milestones according to schedule, or at all;
the risk of being required to repurchase the outstanding warrants in the event of a "Fundamental Transaction", and possibility of price protection reset of
the exercise price of the warrants at prices below the exercise price; competition from other biotechnology and pharmaceutical companies;
our reliance on the capabilities and experience of our key executives and scientists and the resulting loss of any of these individuals;
our ability to fully realize the benefits of acquisitions;
our ability to adequately protect our intellectual property and trade secrets;
our ability to source and maintain licenses from third-party owners;
the risk of patent-related litigation;
the risk of loss of our status as a foreign private issuer, or FPI; and
our expectations regarding our status as a passive foreign investment company, or PFIC,

all as further and more fully described under the heading "Risk Factors" in this AIF.

Although  the  forward-looking  statements  contained  in  this  AIF  are  based  upon  what  our  management  believes  to  be  reasonable  assumptions,  we  cannot  assure
readers that actual results will be consistent with these forward-looking statements.

Any  forward-looking  statements  represent  our  estimates  only  as  of  the  date  of  this  AIF  and  should  not  be  relied  upon  as  representing  our  estimates  as  of  any
subsequent date. We undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such
statement is made or to reflect the occurrence of unanticipated events, except as may be required by securities legislation.

All references in this AIF to "the Company", "Trillium", "we", "us", or "our" refer to Trillium Therapeutics Inc. and the subsidiaries through which it conducts its
business, unless otherwise indicated.

All dollar amounts are in thousands of US dollars, other than per share amounts and unless otherwise indicated.

CORPORATE INFORMATION

The  Company  was  incorporated  under  the  Business  Corporations  Act  (Alberta)  on  March  31,  2004  as  Neurogenesis  Biotech  Corp.  On  October  19,  2004,  the
Company amended its articles of incorporation to change its name to Stem Cell Therapeutics Corp., or SCT, and on November 7, 2013 SCT was continued under
the Business Corporations Act (Ontario).  Articles  of  amalgamation  were  filed  on  June  1,  2014  to  amalgamate  SCT  with  its  wholly-owned  subsidiary,  Trillium
Therapeutics Inc., or Trillium Privateco, and the amalgamated entity continued to operate under the name Trillium Therapeutics Inc. On December 18, 2019, we
were continued under the laws of the Province of British Columbia. The Company is now governed under the Business Corporations Act (British Columba), or
BCBCA. Additionally, on December 18, 2019, the Company adopted new articles which are substantially similar to its previous by-laws of the Company but for
changes that were required to made in accordance with the BCBCA.

We are a company domiciled in Ontario, Canada.  Our head office is located at 2488 Dunwin Drive, Mississauga, Ontario, Canada, L5L 1J9. Our registered office
is  located  at  Suite  1750-1055  W.  Georgia  Street,  P.O.  Box  11125,  Vancouver,  British  Columbia,  V6E  3P3.    We  have  one  wholly-owned  subsidiary,  Trillium
Therapeutics  USA Inc.,  which  was  incorporated  March  26,  2015  in the  State  of  Delaware,  with  an  office  in Cambridge,  Massachusetts.  Our website  address  is
www.trilliumtherapeutics.com.

Our common shares are listed on the Toronto Stock Exchange, or TSX, and the Nasdaq Capital Market, or Nasdaq, under the symbol "TRIL".

Fiscal 2020 (January 1, 2020 - March 5, 2020)

GENERAL DEVELOPMENT OF THE BUSINESS - 3 YEAR SUMMARY

Effective February 6, 2020, Mr. Paul Walker was appointed to the board of directors of the Company, or the board of directors, and Dr. Ali Behbahani joined as a
Board Observer. Both Mr. Walker and Dr. Behbahani are general partners of New Enterprise Associates, a global venture capital firm and an existing significant
shareholder  of  the  Company.  We  also  announced  that  Dr.  Robert  Uger  stepped  down  from  the  Board  of  Directors  effective  February  6,  2020  and  continues  as
Trillium's Chief Scientific Officer.

In January 2020, we completed an underwritten public offering for gross proceeds of $116,955 comprised of 41,279,090 common shares and 1,250,000 Series II
Non-Voting Convertible First Preferred Shares, or Series II First Preferred Shares, each issued at $2.75 per share.

On January 16, 2020, we announced that we had regained compliance with the Nasdaq minimum bid price requirement, and the matter was closed. According to
the letter received from the Nasdaq Listing Qualifications Department, the closing bid price of our common shares had been at $1.00 per common share or greater
for a minimum of 10 consecutive days, and we had regained compliance with the minimum bid price requirement set forth in Rule 5550(a)(2) for continued listing
on the Nasdaq. In April 2019, the Company received a notification letter from Nasdaq notifying the Company that it was not in compliance with the minimum bid
price requirement set forth in the Nasdaq Listing Rules for continued listing in Nasdaq.

On January 7, 2020, we announced that intravenous TTI-621 dose escalation under initial dose limiting toxicity, or DLT, criteria was completed, and the results
confirmed  TTI-621 monotherapy  activity (including  complete  responses) in hematologic  malignancies  at doses up to 0.5 mg/kg. We are currently  dosing at 1.0
mg/kg,  or  5  times  the  dose  level  at  which  we  observed  initial  single  agent  activity.  Further  TTI-621  dose  escalation  under  revised  DLT  criteria  for
thrombocytopenia is in progress. In our TTI-622 phase 1a/1b study, dosing at 2.0 mg/kg has been completed, and dosing at 4.0 mg/kg started in December 2019.

Fiscal 2019

On October 22, 2019, we announced a corporate restructuring program that reduced our staff by 40%, from 43 to 26 active employees. We also decided to out-
license our preclinical STING agonist program. We incurred cash payments of approximately $841 related to employee separation benefits. During the year ended
December 31, 2019, we recognized an impairment  charge of $2,952 to fully write down the remaining carrying value of the intangible assets recognized in the
January  26, 2016 acquisition  of Fluorinov Pharma  Inc.,  or Fluorinov. The  factors  leading  to this impairment  included  the  discontinuation  of discovery  research
activities and revised expected realization from Fluorinov legacy products.

In September 2019, we met with the U.S. Food and Drug Administration, or FDA, which provided guidance on the intratumoral use of TTI-621 for the treatment of
early-stage cutaneous T-cell lymphoma, or CTCL, including aspects of a potential registration study. We announced that the ongoing phase 1b intratumoral trial,
which provided the data set for the FDA interaction and informed the guidance, will be closed.

Effective September 25, 2019, Dr. Jan Skvarka was hired as the President and Chief Executive Officer and was appointed to the board of directors of Trillium.

On July 24, 2019, we provided a corporate update, noting that we amended the TTI-621 intravenous study protocol (NCT02663518) to enable dosing beyond 0.5
mg/kg. We also completed enrollment for the first Simon's 2-stage CTCL cohort in the TTI-621 intravenous study. The Safety Review Committee reviewed the
preliminary data from this cohort and recommended that patients on study continue to be followed until all response assessments are available. We decided not to
initiate the second Simon's 2-stage cohort until the outcome of the ongoing dose escalation is known.

On May 13, 2019, Trillium and the former Fluorinov shareholders amended the purchase agreements to remove the existing milestone and royalty payments in
favour of a revenue sharing arrangement. On the deletion of the milestones from the agreements, the existing contingent consideration was reduced to $nil.

On April 30, 2019, we announced the opening of an office in Cambridge, Massachusetts.  The office houses a portion of Trillium's clinical development team and
is expected to provide access to an expanded talent pool of drug development professionals as Trillium advances its products into later stage development.

On  April  29,  2019,  Niclas  Stiernholm,  Ph.D.,  resigned  as  President  &  Chief  Executive  Officer  and  as  a  director  of  the  Company.  In  the  interim,  the  board  of
directors appointed Robert L. Kirkman, M.D., the current Chair of the board, as Executive Chairman. In addition, Robert Uger, Ph.D., the current Chief Scientific
Officer of Trillium, assumed the role of Interim President. Dr. Uger was also appointed to the board of directors.

On April 15, 2019, we announced the publication of data highlighting the role of TTI-621 in treating patients with Sézary syndrome, or SS, a form of CTCL. The
paper titled "Targeting CD47 in Sézary syndrome with SIRPαFc", published in the April 9th issue of Blood Advances, demonstrates that TTI-621 (SIRPα-IgG1 Fc)
triggers macrophage-mediated phagocytosis of Sézary cells and reduces tumor load in SS patients following intravenous administration. Four of five heavily pre-
treated SS patients had a decrease in the dominant malignant clone and other markers of tumor burden after a single infusion of TTI-621.

On April 2, 2019, we announced that we expanded our immuno-oncology pipeline with a STING agonist program and presented preclinical data from this program
at the 2019 Annual Meeting of the American Association for Cancer Research, or AACR.

On March 8, 2019, we completed an underwritten public offering for gross proceeds of $15,000 comprised of 6,550,000 common share units and 12,200,000 Series
II Non-Voting Convertible First Preferred Share units, each issued at $0.80 per unit. Each common share unit comprised of one common share and one common
share purchase warrant of the Company. Each common share purchase warrant will be exercisable for one common share at a price of $0.96 per common share
purchase warrant for sixty months. Each Series II Non-Voting Convertible First Preferred Share unit comprised of one Series II First Preferred Share and one Series
II Non-Voting Convertible First Preferred Share purchase warrant, or Series II First Preferred Share Warrant. Each Series II First Preferred Share Warrant will be
exercisable for one Series II First Preferred Share at a price of $0.96 per Series II First Preferred Warrant for sixty months.

Fiscal 2018

In December 2018, we provided an update on the safety and anti-tumor activity observed in the phase 1 study of local TTI-621 administration in highly pretreated
patients with relapsed or refractory mycosis fungoides or Sézary syndrome at the American Society of Hematology 60th Annual Meeting. Intratumoral TTI-621
was  well  tolerated  in  27  treated  patients,  with  no  grade  3  or  higher  toxicity  observed.  A  rapid  reduction  in  Composite  Assessment  of  Index  Lesion  Severity
(CAILS) scores, which measure local lesion responses, was observed in 91% (20/22) of patients with available scores across all disease stages, with 41% (9/22)
exhibiting a 50% or greater decrease in CAILS scores. Similar CAILS-based changes were seen in adjacent non-injected lesions, suggesting local regional effects
that were not confined to the site of injection. Continuation monotherapy beyond the initial two week induction period led to further reductions in CAILS scores in
3/4  evaluable  patients  and  evidence  of  systemic  effects  were  observed  in  one  patient.  In  addition,  emerging  translational  data  demonstrate  that  local  TTI-621
administration leads to a rapid influx of macrophages and CD8+ T cells.

6

In September 2018, we provided an update of the safety and efficacy of the phase 1a/b intravenous trial of TTI-621 in patients with relapsed/refractory hematologic
malignancies at the 16th Annual Discovery on Target conference. Based on an expanded data set of 163 patients, weekly infusions of TTI-621 were shown to be
well  tolerated.  Thrombocytopenia was the  most  frequent grade  3  or  higher treatment-emergent adverse  event, occurring in  20%  of  patients. Platelet  reductions,
however, were shown to be transient and pre-dose platelet levels remained steady during the course of the study. Notably, the reversible thrombocytopenia did not
lead  to  an  increased  risk  of  bleeding  and  had  no  impact  on  drug  delivery,  nor  was  there  a  significant  impact  of  TTI-621  on  hemoglobin  levels.  Monotherapy
efficacy was observed in patients with mycosis fungoides (19% ORR, n=21), peripheral T-cell lymphoma, or PTCL (25% ORR, n=12), and diffuse large B-cell
lymphoma, or DLBCL (25% ORR, n=8), and in DLBCL patients when combined with rituximab (25% ORR, n=24). This clinical activity was observed in patients
receiving relatively low doses of drug (0.2 mg/kg for monotherapy or 0.1 mg/kg in combination with rituximab).

In June 2018, we initiated dosing in our multicenter, open-label, phase 1a/1b study of TTI-622 (SRIPaFc-IgG4) in patients with advanced relapsed or refractory
lymphoma  or  multiple  myeloma.  In  the  phase  1a  dose-escalation  part,  patients  are  enrolled  in  sequential  dose  cohorts  to  receive  TTI-622  once  weekly  to
characterize safety, tolerability, pharmacokinetics, and to determine the maximum tolerated dose.

In  June  2018,  we  entered  into  a  Second  Amended  and  Restated  License  Agreement  with  University  Health  Network  and  The  Hospital  for  Sick  Children,  or
collectively,  the Licensors. Under the amended agreement,  the sublicense revenue  sharing provisions were removed in return for a payment to the Licensors of
CDN $3,000 in the form  of 369,621 common  shares.  On the  issuance of the CDN $3,000 of common  shares,  Trillium  will retain  100% of any potential  future
sublicense revenues, other than royalties on net sales.

In April 2018, Yaping Shou MD, Ph.D., joined Trillium as Chief Medical Officer.

In April 2018, we presented preclinical data from our TTI-622 (SIRPa-IgG4 Fc) immune checkpoint inhibitor program at the 109th AACR Annual Meeting. The
data presented at AACR demonstrated that TTI-622 induces the phagocytosis of a broad panel of tumor cells derived from patients with both hematological and
solid  tumors.  As  a  monotherapy,  TTI-622  treatment  resulted  in  decreased  tumor  growth  and  improved  survival  in  a  B  cell  lymphoma  xenograft  model,  and
enhanced  the  efficacy  of  cetuximab  (anti-EGFR)  and  daratumumab  (anti-CD38)  antibodies  in  solid  and  hematological  xenograft  models,  respectively.  Unlike
CD47-blocking antibodies, TTI-622 bound minimally to human erythrocytes and did not induce hemagglutination in vitro.

On March 20, 2018, we announced that we received an Orphan Drug Designation to TTI-621 for the treatment of cutaneous T-cell lymphoma from the FDA Office
of Orphan Products Development.

Fiscal 2017

In  December  2017,  we  presented  data  at  the  2017  American  Society  of  Hematology,  or  ASH,  Annual  Meeting  showing  locoregional  tumor  regression  in  9/10
cutaneous T cell lymphoma patients receiving intratumoral TTI-621 monotherapy, often after a single injection. We also presented data at the 2017 ASH Annual
Meeting demonstrating that heavily pre-treated patients with relapsed/refractory diffuse large B cell lymphoma can achieve objective responses and/or prolonged
progression-free intervals, following intravenous administration of TTI-621 either as monotherapy or in combination with rituximab. ASH data indicate that TTI-
621 is well tolerated by both routes of administration; notably, the transient thrombocytopenia observed after intravenous dosing was shown to be attenuated after
the first dose.

7

On  December  1,  2017,  we  completed  a  non-brokered  private  placement  of  1,950,000  common  shares  and  400,000  Series  II  First  Preferred  Shares  at  a  price  of
$8.50 per share for gross proceeds of $19,975.

In October 2017, preclinical data and a patient case study for its CD47-blocking agent, TTI-621 (SIRPa-IgG1 Fc), were presented at the EORTC CLTF meeting
"Cutaneous Lymphomas - Insights and Therapeutic Progress", in London, England. This oral presentation highlighted that leukemic cells from patients with Sézary
syndrome, express the CD47 "do not eat" signal at almost four times the level of normal lymphocytes and that over-expression of CD47 is associated with poor
prognosis.  The  case  study  reported  local  and  systemic  anti-tumor  activity  in  a  Sézary  syndrome  patient  treated  with  a  single  intratumoral  dose  of  TTI-621.
Administration  of  PEGylated  Interferon-α2a  seven  days  after  TTI-621  resulted  in  decreased  leukemic  burden  and  improvements  in  clinical  symptoms.  Trillium
believes  such  a  reduction  is  not  observed  regularly  with  standard  regimens  and  would  not  be  anticipated  following  PEGylated  Interferon-α2a  monotherapy,
suggesting a synergistic effect of TTI-621 and PEGylated Interferon-α2a.

On October 11, 2017, we announced that Dr. Helen Tayton-Martin had been appointed to our board of directors.

In June 2017, we completed an underwritten public offering of common shares and Series II First Preferred Shares in the United States. In the offering, we sold
2,949,674 common shares and 3,250,000 Series II First Preferred Shares at a price of $5.00 per share. The gross proceeds from this offering were $30,998.

In  February  2017,  we  presented  additional  pharmacology  data  from  our  ongoing  intravenous  trial  of  TTI-621  at  the  ASCO-SITC  Clinical  Immuno-Oncology
Symposium. These data suggest that: repeat  weekly dosing of TTI-621 leads to a longer half-life  and accumulation  of circulating  drug, overcoming  the platelet
antigen sink;  the transient  decrease  in platelets  observed immediately  following TTI-621 exposure was attenuated  in most patients  receiving  multiple  infusions;
compared to the initial infusion, the extent and duration of CD47 occupancy on peripheral leukocytes was elevated following the sixth dose suggesting increased
receptor occupancy on circulating leukemic blast cells; and increases in cytokines associated with macrophage activation are consistent with rapid engagement of
the innate immune system.

In January 2017, we initiated dosing in our second phase 1 clinical trial with TTI-621 in patients with relapsed or refractory percutaneously-accessible solid tumors
and mycosis fungoides.

Overview

BUSINESS

We  are  a  clinical  stage  immuno-oncology  company  developing  innovative  therapies  for  the  treatment  of  cancer.  Our  most  advanced  program,  TTI-621,  is  a
SIRPαFc fusion protein that consists of the extracellular CD47-binding domain of human signal regulatory protein alpha, or SIRPα, linked to the Fc region of a
human  immunoglobulin  G1,  or  IgG1.  It  is  designed  to  act  as  a  soluble  decoy  receptor,  preventing  CD47  from  delivering  its  inhibitory  ("do  not  eat")  signal.
Neutralization of the inhibitory CD47 signal enables the activation of macrophage anti-tumor effects by pro-phagocytic ("eat") signals. The IgG1 Fc region of TTI-
621 may also assist in the activation of macrophages by engaging Fc receptors. TTI-621 has shown single agent activity by both local and/or systemic delivery in
multiple B- and T-cell lymphoma indications and has been well tolerated in over 200 patients to date.

We are also developing a second SIRPαFc fusion protein, TTI-622, which is in a phase 1 clinical trial. TTI-622 consists of the extracellular CD47-binding domain
of human SIRPα linked to a human immunoglobulin G4, or IgG4 Fc region, which has a decreased ability to engage Fc receptors than an IgG1 Fc. Both SIRPαFc
fusion proteins enable CD47 blockade with different levels of Fc receptor engagement on macrophages and thus may find unique applications.

We also have an internally-developed small molecule stimulator of interferon genes, or STING, agonist program available for out-license.

Our Strategy

Our goal is to become a leading innovator in the field of oncology by targeting immune-regulatory pathways that tumor cells exploit to evade the host immune
system. We believe we have a differentiated and comprehensive approach to targeting CD47, with the development of two SIRPαFc fusion proteins, TTI-621 and
TTI-622. We intend to:

Rapidly advance the clinical development of TTI-621 and TTI-622. We are currently in the process of identifying the maximum tolerated or
recommended phase 2 doses for both TTI-621 and TTI-622, and plan to rapidly advance both molecules into phase 1b/2 studies.

Focus our TTI-621 and TTI-622 clinical programs on promising cancer indications. Because CD47 is highly expressed by multiple liquid and solid
tumors, and high expression is correlated with worse clinical outcomes, we believe our SIRPαFc fusion proteins have the potential to be effective in a
variety of cancers. We have already identified several cancers where we saw positive responses to TTI-621 in patients, including B- and T-cell
lymphomas.

Focus our TTI-621 and TTI-622 clinical programs on promising combinations. While we believe that a monotherapy path for TTI-621 in certain
indications shows promise, we are also planning to evaluate TTI-621 and TTI-622 in combination with other anti-cancer drugs, including
immunomodulatory agents.

Our Pipeline

SIRPαFc

Blocking the CD47 "do not eat" signal using a SIRPαFc decoy receptor

The immune system is the body's mechanism  to identify  and eliminate  pathogens, and can be divided into the innate immune  system and the adaptive  immune
system. The innate immune system is the body's first line of defense to identify and eliminate pathogens and consists of proteins and cells, such as macrophages,
that  identify  and  provide  an  immediate  response  to  pathogens.  The  adaptive  immune  system  is  activated  by,  and  adapts  to,  pathogens,  creating  a  targeted  and
durable response. Cancer cells often have the ability to reduce the immune system's ability to recognize and destroy them.

Macrophages  are  a  type  of  white  blood  cell  that  can  ingest  and  destroy  (phagocytose)  other  cells.  Macrophage  activity  is  controlled  by  both  positive  "eat"  and
negative "do not eat" signals. Recently, a role for macrophages in the control of tumors has been described. Tumor cells may express "eat" signals (e.g. calreticulin)
that make themselves visible to macrophages. To counterbalance this increased visibility the tumor cells often express high levels of CD47, which transmits a "do
not eat" signal by binding SIRPα on the surface of macrophages. Elevated expression of CD47 has been observed across a range of hematological and solid tumors.
In many cases, high CD47 expression was shown to have negative clinical consequences, correlating with more aggressive disease and poor survival.

9

Our most advanced program, TTI-621, is a novel SIRPαFc fusion protein that harnesses the innate immune system by blocking the activity of CD47. TTI-621 is a
protein that consists of the CD47-binding domain of human SIRPα linked to the Fc region of IgG1. It is designed to act as a soluble decoy receptor, preventing
CD47  from  delivering  its  inhibitory  signal.  Neutralization  of  the  inhibitory  CD47  signal  enables  the  activation  of  macrophage  anti-tumor  effects  by  the  pro-
phagocytic "eat" signals. The IgG1 Fc region of TTI-621 may also assist in the activation of macrophages by engaging Fc receptors. Our second SIRPαFc fusion
protein TTI-622 consists of the same CD47-binding domain of human SIRPα and is linked to the Fc region of IgG4. The IgG4 Fc region of TTI-622 is expected to
have  a  decreased  ability  to  engage  activating  Fc  receptors  compared  to  an  IgG1 Fc, and  thus  provide  a  more  modest  "eat"  signal  to  macrophages,  allowing  for
greater tolerability and higher CD47 blockade but lower potency. TTI-622 will allow us to assess how higher CD47 blockade with an IgG4-based agent in patients
compares to lower CD47 blockade with an IgG1-based drug (TTI-621).

In preclinical studies, TTI-621 and TTI-622 frequently triggered significant macrophage-mediated tumor cell phagocytosis in vitro compared to control treatment.
In vivo, both fusion proteins exhibited anti-tumor activity in human xenograft models.

In addition to their direct anti-tumor activity, macrophages can also function as antigen-presenting cells and stimulate antigen-specific T-cells. Thus, it is possible
that increasing tumor cell phagocytosis after SIRPαFc exposure may result in enhanced adaptive immunity. In support of this, CD47 antibody blockade has been
recently  shown  to  augment  antigen  presentation  and  prime  an  anti-tumor  cytotoxic  T-cell  response  in  immune-competent  mice.  In  2016,  we  presented  data
demonstrating  that  TTI-621  can  augment  antigen-specific  T-cell  responses  in  vitro.  CD47  blockade  has  also  been  reported  to  promote  tumor-specific  T-cell
responses through a dendritic cell-based mechanism, although the effect of SIRPαFc on dendritic cells is currently unknown.

The  figure  below  illustrates  how  SIRPαFc  blocks  the  CD47  "do  not  eat"  signal  and  engages  activating  Fc  receptors  on  macrophages,  leading  to  tumor  cell
phagocytosis, increased antigen presentation and enhanced T-cell responses.

10

By inhibiting the CD47 "do not eat" signal, we believe SIRPαFc has the ability to promote the macrophage-mediated killing of tumor cells in a broad variety of
cancers both as a monotherapy and in combination with other immune therapies. Both SIRPαFc fusion proteins enable CD47 blockade with different levels of Fc
receptor engagement on macrophages and thus may find unique applications.

Combination Therapy

We believe that SIRPαFc enhancement of macrophage activity, and possibly T-cell responses, could be synergistic with other immune-mediated therapies. Since
many cancer antibodies work at least in part by activating cells of the innate immune system, it may be possible to enhance the potency of these agents by blocking
the  negative  "do  not  eat"  CD47  signal  that  tumor  cells  deliver  to  macrophages.  In  fact,  we  have  observed  anti-tumor  activity  when  combining  SIRPαFc  with
rituximab  in  both  preclinical  studies  and  in  B-cell  lymphoma  patients.  We  hypothesize  that  SIRPαFc  may  act  synergistically  with  other  immunological  agents,
including T-cell checkpoint inhibitors (e.g. pembrolizumab and nivolumab), cancer vaccines, oncolytic viruses or chimeric antigen receptor, or CAR T-cells.

SIRPαFc Clinical Development - TTI-621

A phase 1 multicenter, open-label study in which patients with advanced relapsed or refractory hematologic malignancies receive intravenous TTI-621 is currently
in  progress  (NCT02663518).  The  study  consists  of  four  parts:  (a)  completed  "Parts  1-3"  in  hematologic  malignancies,  with  dosing  up  to  0.5  mg/kg,  conducted
under initial dose-limiting toxicity or DLT criteria; and (b) ongoing "Part 4" in CTCL, utilizing revised DLT criteria for thrombocytopenia (as detailed below) and
an amended protocol to allow for dosing above 0.5 mg/kg.

On January 7, 2020, we released updated from Parts 1-3 of the TTI-621 intravenous study. Over 200 patients received doses ranging from 0.05 to 0.5 mg/kg, with
the majority enrolled at 0.2-0.5 mg/kg dose levels. Updated safety data demonstrate that TTI-621 is generally well tolerated. The most frequent drug related adverse
events were low-grade infusion reactions and transient thrombocytopenia that was not associated with bleeding. Monotherapy activity has been observed in patients
across a range of hematologic malignancies, including CTCL (19% objective response rate), peripheral T-cell lymphoma, or PTCL (18% objective response rate),
and diffuse large B-cell lymphoma (29% objective response rate). Notably, most patients were at an advanced stage of their disease and heavily pretreated, with
median number of prior systemic treatments between 3 and 5 (range 1-26).

Part  4  of  the  study  is  now  ongoing  under  an  amended  protocol.  Given  the  transient  nature  of  thrombocytopenia  observed  in  Parts  1-3  of  the  study,  the  DLT
definition for thrombocytopenia was revised, from Grade 4 of any duration in Parts 1-3, to Grade 4 lasting 72+ hours or a platelet count less than 10,000/microliter
at  any  time  in  Part  4.  No  DLTs  have  been  observed  at  the  0.5  and  0.7  mg/kg  dose  levels;  furthermore  no  Grade  4  thrombocytopenia  of  any  duration  has  been
observed. The study is now dosing at the 1.4 mg/kg level, and the protocol allows for higher dosing if appropriate.

We  have  also  conducted  an  open-label  phase  1  trial  in  which  TTI-621  was  delivered  by  intratumoral  injection  in  patients  with  relapsed  and  refractory,
percutaneously-accessible cancers. As reported at the American Society of Hematology 60th Annual Meeting in December 2018, local delivery of TTI-621 was
well tolerated, and reductions in Composite Assessment of Index Lesion Severity, or CAILS, scores, which measure local lesion responses, were observed in 91%
of evaluable mycosis fungoides patients, with 41% exhibiting reductions of 50% or greater. These responses occurred rapidly within the 2-week induction period.
Collectively,  these  data  provide  clinical  proof-of-concept  for  TTI-621.  As  announced  in  October  2019,  the  intratumoral  study  has  been  closed  and  we  are  now
focused on intravenous delivery of TTI-621.

TTI-621 was granted an Orphan Drug Designation by the FDA for the treatment of CTCL. Orphan Drug Designation qualifies the sponsor of the drug candidate for
various development incentives, which may include tax credits for qualified clinical testing, an exemption from fees under the Prescription Drug User Fee Act, and
a seven-year marketing exclusivity period following approval.

SIRPαFc Clinical Development - TTI-622

A two-part, multicenter, open-label, phase 1a/1b study of TTI-622 in patients with advanced relapsed or refractory lymphoma or multiple myeloma is currently in
progress  (NCT03530683).  In  the  phase  1a  dose-escalation  part,  patients  are  being  enrolled  in  sequential  dose  cohorts  to  receive  TTI-622  once  weekly  to
characterize safety, tolerability, pharmacokinetics, and to determine the maximum tolerated dose. In the phase 1b part, patients with hematologic malignancies will
be treated with TTI-622 in combination with other agents.

On January 7, 2020, we reported that we have completed dosing in the fourth dose escalation cohort, where patients received a top dose of 2.0 mg/kg. No DLTs or
drug-related  serious  adverse  events  have  been  observed,  and  enrollment  is  now  open  in  the  sixth  cohort,  with  a  dose  of  8.0  mg/kg.  Although  TTI-622  is  being
developed primarily as a combination therapy, a partial response has been observed in a DLBCL patient receiving 0.8 mg/kg TTI-622 monotherapy.

SIRPαFc Key Takeaways

Multiple clinical approaches. We have a diversified approach to CD47 blockade, with two decoy receptors (TTI-621 and TTI-622) with different
pharmacological properties in clinical development.

Tolerability and safety. TTI-621 has been well tolerated in over 200 patients to date.

Demonstrated clear signals of activity. TTI-621 monotherapy has produced positive signals of clinical activity in CTCL, PTCL and DLBCL patients. A
signal of activity was also seen in DLBCL patients when combined with rituximab.

SIRPαFc Competition

There are a number of companies developing blocking agents to the CD47-SIRPα axis, which can be broadly classified into six groups which include, but are not
limited to:

CD47-specific antibodies: Forty Seven Inc (phase 2); Celgene Corporation (phase 1), Innovent Biologics (Suzhou) Co. (phase 1), Arch Oncology (phase
1), I -Mab Biopharma (phase 1), Jiangsu Hengrui Medicine Co. (phase 1), Seattle Genetics (phase 1); Phanes Therapeutics (preclinical), ImmuneOncia
(preclinical), Eucure Biopharma (preclinical), Elpiscience (preclinical).
CD47 bispecific antibodies: TG Therapeutics/Light Chain Bioscience (phase 1), Abpro Therapeutics (preclinical), Hummingbird BioSciences
(preclinical), ImmuneOncia (preclinical), Innovent Biologics (Suzhou) Co. (preclinical), Pharmabcine (preclinical), Phanes Therapeutics (preclinical)
Mutated high affinity SIRPαFc: ALX Oncology (phase 1).
SIRPα-specific antibodies: Celgene, OSE Immunotherapeutics/Boehringer Ingelheim (phase 1); Arch Oncology (preclinical), Forty Seven Inc
(preclinical), Compass Therapeutics (preclinical), Elpiscience (preclinical).
SIRPαFc-agonist fusion protein: Shattuck Labs (preclinical).
Small molecule inhibitor: Aurigene Discovery Technologies (preclinical), Paradigm Shift Therapeutics (preclinical), Vivoryon AG (preclinical).

We believe that IgG1 Fc region differentiates TTI-621 from most other CD47 blocking agents. The IgG1 Fc maximizes potency by delivering an activating signal
to  macrophages  through  Fc  receptors.  With  this  higher  potency,  we  believe  that  TTI-621  has  a  higher  likelihood  of  monotherapy  activity  and  therefore  is  not
dependent upon a combination with another IgG1 antibody. Indeed, to our knowledge TTI-621 is the only CD47 blocking agent which has exhibited meaningful
monotherapy activity and resulted in complete responses in cancer patients as a monotherapy.

Furthermore, we believe that both TTI-621 and TTI-622 are differentiated from other CD47 blocking agents by minimal binding to human red blood cells. This
property  confers  several  possible  advantages,  including  avoidance  of  drug-induced  anemia,  avoidance  of  the  "antigen  sink  effect"  (i.e.  removal  of  drug  from
circulation by RBCs) and non-interference with laboratory blood typing tests.

12

STING Agonist

Our pipeline also includes a preclinical STING (stimulator of interferon genes) agonist program. STING is an adaptor protein involved in sensing cytosolic DNA
that plays a key role in promoting tumor immunity. As previously announced, the program is earmarked for out-licensing.

Plan of Operations

Our main focus in the near term is to 1) identify the maximum tolerated dose or recommended phase 2 dose for TTI-621 under the revised DLT criteria in Part 4 of
study NCT02663518 and 2) identify the maximum tolerated dose or recommended phase 2 dose for TTI-622 in the ongoing study NCT03530683. Subsequently,
we intend to initiate phase 1b/2 combination studies for both agents. For TTI-621, we are also considering a monotherapy expansion cohort in T-cell lymphoma.
We will also undertake research, manufacturing and regulatory activities to support the CD47 clinical programs.

Fluorinov Amendment

On  January  26,  2016,  Trillium  purchased  all  the  issued  and  outstanding  shares  of  Fluorinov,  a  private  oncology  company,  to  access  its  proprietary  medicinal
chemistry  platform.  On May  13, 2019, Trillium  and the former  Fluorinov  shareholders  amended  the purchase  agreements  to remove  the existing  milestone  and
royalty payments in favour of a revenue sharing arrangement. On the deletion of the milestones from the agreements, the existing contingent consideration was
reduced to $nil.

Intellectual Property

We own or control patent rights covering our key products and their therapeutic end uses. The patents and patent applications are either granted or pending in major
pharmaceutical  markets.  In  all,  the  patent  estate  includes  inventions  in  three  different  areas  that  include  SIRPα,  and  modified  new  chemical  entities.  These  are
supported by numerous patents and applications. In connection specifically with patent coverage for SIRPαFc, we control two patent families. One family relates to
the  use  of  SIRPα  to  treat  cancer.  The  other  family  relates  to  our  drug  as  a  composition  of  matter,  SIRPαFc.  We  have  also  filed  for  patent  protection  covering
additional inventions relating to SIRPα, including anti-cancer drug combination therapies that utilize SIRPαFc, and biomarkers that identify SIRPαFc responders.

We intend to protect additional intellectual property developed by us through the filing of patent applications within appropriate jurisdictions throughout the world.

Regulatory Process

Government  authorities  in  the  United  States,  including  federal,  state,  and  local  authorities,  and  in  other  countries,  extensively  regulate,  among  other  things,  the
manufacturing,  research  and  clinical  development,  marketing,  labeling  and  packaging,  storage,  distribution,  post-approval  monitoring  and  reporting,  advertising
and promotion, and export and import of biological products, such as those we are developing. The process of obtaining regulatory approvals and the subsequent
compliance with appropriate federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources.

Securing final regulatory approval for the manufacture and sale of biological products in the US, Europe, Canada and other commercial territories, is a long and
costly process that is controlled by that particular territory's regulatory agency. The regulatory agency in the US is the FDA, in Canada it is Health Canada, or HC,
and in Europe it is the European Medicines Agency. Other regulatory agencies have similar regulatory approval processes, but each regulatory agency has its own
approval processes. Approval in the US, Canada or Europe does not assure approval by other regulatory agencies, although often test results from one country may
be used in applications for regulatory approval in another country.

None of our products have been completely developed or tested and, therefore, we are not yet in a position to seek final regulatory approval to market any of our
products.  The  time  required  to  obtain  approval  by  such  regulatory  authorities  is  unpredictable  but  typically  takes  many  years  following  the  commencement  of
preclinical studies and clinical trials and will require significant additional capital. See "Risk Factors - Risks Related to our Business and our Industry" below.

US Government Regulation

In the US, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing regulations, and biologics under the FDCA
and the Public Health Service Act, or PHSA, and its implementing regulations. FDA approval is required before any new unapproved drug or biologic or dosage
form, including a new use of a previously approved drug, can be marketed in the United States. Drugs and biologics are also subject to other federal, state, and local
statutes and regulations. If we fail to comply with applicable FDA or other requirements at any time during the product development process, clinical testing, the
approval  process  or  after  approval,  we  may  become  subject  to  administrative  or  judicial  sanctions.  These  sanctions  could  include  the  FDA's  refusal  to  approve
pending applications, license suspension or revocation, withdrawal of an approval, warning letters, product recalls, product seizures, total or partial suspension of
production or distribution, civil monetary penalties or criminal prosecution. Any FDA enforcement action could have a material adverse effect on us.

The process required by the FDA before product candidates may be marketed in the United States generally involves the following:

completion of extensive preclinical laboratory tests and preclinical animal studies, all performed in accordance with the Good Laboratory Practices
regulations;
submission to the FDA of an IND, which must become effective before human clinical trials may begin and must be updated annually;
approval by an independent institutional review board, or IRB, or ethics committee representing each clinical site before each clinical trial may be
initiated;
performance of adequate and well-controlled human clinical trials to establish the safety and efficacy of the product candidate for each proposed
indication;
preparation of and submission to the FDA of a new drug application, or NDA, or biologics license application, or BLA, after completion of all pivotal
clinical trials;
potential review of the product application by an FDA advisory committee, where appropriate and if applicable;
a determination by the FDA within 60 days of its receipt of an NDA or BLA to file the application for review;
satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities where the proposed product is produced to assess compliance
with current Good Manufacturing Practices, or cGMP;
a potential FDA audit of the preclinical research and clinical trial sites that generated the data in support of the NDA or BLA; and
FDA review and approval of an NDA or BLA prior to any commercial marketing or sale of the product in the US

The  preclinical  research  and  clinical  testing  and  approval  process  require  substantial  time,  effort,  and  financial  resources,  and  we  cannot  be  certain  that  any
approvals for our product candidates will be granted on a timely basis, if at all.

An IND is a request for authorization from the FDA to administer an investigational new drug product to humans in clinical trials. The central focus of an IND
submission  is  on  the  general  investigational  plan  and  the  protocol(s)  for  human  clinical  trials.  The  IND  also  includes  results  of  animal  studies  assessing  the
toxicology, pharmacokinetics, pharmacology, and pharmacodynamic characteristics of the product; chemistry, manufacturing, and controls information; and any
available human data or literature to support the use of the investigational new drug. An IND must become effective before human clinical trials may begin. An
IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to the proposed
clinical trials. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before
clinical trials can begin. Accordingly, submission of an IND may or may not result in the FDA allowing clinical trials to commence.

14

Clinical Trials

Clinical  trials  involve  the  administration  of  the  investigational  new  drug  to  human  subjects  under  the  supervision  of  qualified  investigators  in  accordance  with
Good Clinical Practices, or GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial.
Clinical  trials  are  conducted  under  protocols  detailing,  among  other  things,  the  objectives  of  the  study,  the  parameters  to  be  used  in  monitoring  safety,  and  the
efficacy  criteria  to  be  evaluated.  A  protocol  for  each  clinical  trial  and  any  subsequent  protocol  amendments  must  be  submitted  to  the  FDA as  part  of  the  IND.
Additionally,  approval  must  also  be  obtained  from  each  clinical  trial  site's  IRB  or  ethics  committee,  before  the  trials  may  be  initiated,  and  the  IRB  or  ethics
committee must monitor the trial until completed. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public
registries.

The clinical investigation of a drug is generally divided into three or four phases. Although the phases are usually conducted sequentially, they may overlap or be
combined.

Phase I. The drug is initially introduced into healthy human subjects or patients with the target disease or condition. These studies are designed to evaluate
the safety, dosage tolerance, metabolism and pharmacologic actions of the investigational new drug in humans, the side effects associated with increasing
doses, and if possible, to gain early evidence on effectiveness.
Phase II. The drug is administered to a limited patient population to evaluate dosage tolerance and optimal dosage, identify possible adverse side effects
and safety risks, and preliminarily evaluate efficacy.
Phase III. The drug is administered to an expanded patient population, generally at geographically dispersed clinical trial sites to generate enough data to
statistically evaluate dosage, clinical effectiveness and safety, to establish the overall benefit-risk relationship of the investigational new drug product, and
to provide an adequate basis for physician labeling.
Phase IV. In some cases, the FDA may condition approval of an NDA or BLA for a product candidate on the sponsor's agreement to conduct additional
clinical trials after approval. In other cases, a sponsor may voluntarily conduct additional clinical trials after approval to gain more information about the
drug. Such post-approval studies are typically referred to as phase IV clinical trials.

Clinical trial sponsors must also report to the FDA, within certain timeframes, serious and unexpected adverse reactions, any clinically important increase in the
rate  of  a  serious  suspected  adverse  reaction  over  that  listed  in  the  protocol  or  investigator's  brochure,  or  any  findings  from  other  studies  or  animal  testing  that
suggest a significant risk in humans exposed to the product candidate. The FDA, the IRB or ethics committee, or the clinical trial sponsor may suspend or terminate
a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Additionally, some
clinical  trials  are  overseen  by  an  independent  group  of  qualified  experts  organized  by  the  clinical  trial  sponsor,  known  as  a  data  safety  monitoring  board  or
committee. This group provides authorization for whether or not a trial may move forward at designated check points based on access to certain data from the trial.

The clinical trial process can take years to complete, and there can be no assurance that the data collected will support FDA approval or licensure of the product.
Results  from  one  trial  are  not  necessarily  predictive  of  results  from  later  trials.  We  may  also  suspend  or  terminate  a  clinical  trial  based  on  evolving  business
objectives and/or competitive climate.

Submission of an NDA or BLA to the FDA

Assuming  successful  completion  of  all  required  preclinical  studies  and  clinical  testing  in  accordance  with  all  applicable  regulatory  requirements,  detailed
investigational new drug product information is submitted to the FDA in the form of an NDA or BLA requesting approval to market the product for one or more
indications. Under federal law, the submission of most NDAs and BLAs is subject to an application user fee. For fiscal year 2019, the application user fee exceeds
$2,588, and the sponsor of an approved NDA or BLA is also subject to annual product and establishment user fees. These fees are typically increased annually.
Applications for orphan drug products are exempted from the NDA and BLA application user fee, unless the application includes an indication for other than a rare
disease or condition, and may be exempted from product and establishment user fees under certain conditions.

15

An NDA or BLA must include all relevant data available from pertinent preclinical studies and clinical trials, including negative or ambiguous results as well as
positive findings, together with detailed information relating to the product's chemistry, manufacturing, controls, and proposed labeling, among other things. Data
comes from company-sponsored clinical trials intended to test the safety and effectiveness of a use of a product, and may also come from a number of alternative
sources,  including  trials  initiated  by  investigators.  To  support  marketing  approval,  the  data  submitted  must  be  sufficient  in  quality  and  quantity  to  establish  the
safety and effectiveness of the investigational new drug product to the satisfaction of the FDA.

Once  an  NDA  or  BLA  has  been  submitted,  the  FDA's  goal  is  to  review  the  application  within  ten  months  after  it  accepts  the  application  for  filing,  or,  if  the
application  relates  to an unmet  medical  need  in  a serious  or  life-threatening  indication,  six  months after  the  FDA accepts  the  application  for filing.  The review
process is often significantly extended by the FDA's requests for additional information or clarification.

Before  approving  an  NDA  or  BLA,  the  FDA  typically  will  inspect  the  facility  or  facilities  where  the  product  is  manufactured.  The  FDA  will  not  approve  an
application  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent
production of the product within required specifications. Additionally, before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites
to assure compliance with GCP.

The FDA is required to refer an NDA or BLA for a novel drug (in which no active ingredient has been approved in any other application) to an advisory committee
or explain why such referral was not made. Typically, an advisory committee is a panel of independent experts, including clinicians and other scientific experts,
that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the
recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

The FDA's Decision on an NDA or BLA

After the FDA evaluates the NDA or BLA and conducts inspections of manufacturing facilities where the product will be produced, the FDA will issue either an
approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific
indications. A Complete Response Letter indicates that the review cycle of the application is complete and the application is not ready for approval. In order to
satisfy  deficiencies  identified  in  a  Complete  Response  Letter,  additional  clinical  data  and/or  an  additional  phase  III  clinical  trial(s),  and/or  other  significant,
expensive and time-consuming requirements related to clinical trials, preclinical studies or manufacturing may be required for the product candidate. Even if such
additional information is submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. The FDA could also approve
the NDA or BLA with a risk evaluation and mitigation strategy, plan to mitigate risks, which could include medication guides, physician communication plans, or
elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on,
among  other  things,  changes  to  proposed  labeling,  development  of  adequate  controls  and  specifications,  or  a  commitment  to  conduct  one  or  more  post-market
studies  or  clinical  trials.  Such  post-market  testing  may  include  phase  IV  clinical  trials  and  surveillance  to  further  assess  and  monitor  the  product's  safety  and
effectiveness after commercialization. New government requirements, including those resulting from new legislation, may be established, or the FDA's policies
may change, which could delay or prevent regulatory approval of our products under development.

Patent Term Restoration

Depending upon the timing, duration, and specifics of the FDA approval of the use of our product candidates, some of our US patents may be eligible for limited
patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The
Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA
regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product's approval
date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA or BLA, plus the
time  between  the  submission  date  and  the  approval  of  that  application.  Only  one  patent  applicable  to  an  approved  product  is  eligible  for  the  extension  and  the
application for the extension must be submitted prior to the expiration of the patent and within 60 days of the product's approval. The US Patent and Trademark
Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we may apply for restoration
of patent  term for one of our currently  owned or licensed  patents  to add patent life  beyond its current  expiration  date, depending  on the expected  length  of the
clinical trials and other factors involved in the filing of the relevant NDA or BLA.

16

Companion Diagnostics

In its August 6, 2014, guidance document entitled "In Vitro Companion Diagnostic Devices," the FDA defines an IVD companion diagnostic device to be an in
vitro diagnostic device that provides information that is essential for the safe and effective use of a corresponding therapeutic product. Use of an IVD companion
diagnostic device is considered essential when its use is required in the labeling of a therapeutic product, for example, to select appropriate patients for a product or
those who should not use the product, or to monitor patients to achieve safety or effectiveness. In most circumstances, the IVD companion diagnostic device should
be  approved  or  cleared  by  FDA  under  the  device  authorities  of  the  FDCA  contemporaneously  with  the  therapeutic  product's  approval  under  section  505  of  the
FDCA for a drug or section 351 of the PHSA for a biological product. FDA expects the therapeutic product sponsor to address the need for an approved or cleared
IVD companion diagnostic device in its therapeutic product development plan. The therapeutic product sponsor may develop its own IVD companion diagnostic
device,  partner  with  a  diagnostic  device  sponsor  to  develop  an  IVD  companion  diagnostic  device,  or  explore  modifying  an  existing  IVD  diagnostic  device  to
develop  a  new  intended  use.  The  FDA  explains  if  a  diagnostic  device  and  a  therapeutic  device  are  studied  together  to  support  their  respective  approvals,  both
products can be studied in the same investigational study that meets both the requirements of the Investigational Device Exemption, or IDE, regulations and the
IND regulations. Depending on the study plan and participants, a sponsor may seek to submit an IND alone, or both an IND and IDE.

Raw Materials, Manufacturing, and Supply

We have limited experience in manufacturing products for clinical or commercial purposes. We produce small quantities of our products in our laboratories for
internal  use.  We  believe  that  sources  of  raw  materials  pertinent  to  our  laboratory  operations  and  for  manufacturing  of  our  products  by  a  CMO  are  generally
available.

We have established a contract manufacturing relationship for the supply of SIRPαFc that we believe will provide sufficient material for early clinical trials. In
addition, we are establishing the basis for long-term commercial production capabilities. However, there can be no assurance that our contract manufacturer will be
successful at scaling up and producing our product with the required quality and in the quantities and timelines that we will need for clinical and/or commercial
purposes.

We expect to similarly rely on contract manufacturing relationships for any products that we may further develop, or in-license or acquire in the future. However,
there can be no assurance that we will be able to successfully contract with such manufacturers on terms acceptable to us, or at all.

Contract manufacturers are subject to ongoing periodic and unannounced inspections by the FDA, the US  Drug Enforcement Administration and corresponding
state agencies to ensure strict compliance with cGMP and other state and federal regulations. We do not have control over third-party manufacturers' compliance
with these regulations and standards, other than through contractual obligations and periodic auditing. If they are deemed out of compliance with such regulations,
approvals could be delayed, product recalls could result, inventory could be destroyed, production could be stopped and supplies could be delayed or otherwise
disrupted.

If we need to change manufacturers after commercialization, the FDA and corresponding foreign regulatory agencies must approve these new manufacturers in
advance, which will involve testing and additional inspections to ensure compliance with FDA regulations and standards and may require significant lead times and
delay, and disruption of supply. Furthermore, switching manufacturers may be difficult because the number of potential manufacturers is limited. It may be difficult
or impossible for us to find a replacement manufacturer quickly or on terms acceptable to us, or at all.

Property, Plant and Equipment

We  operate  from  approximately  22,000  square  feet  of  leased  laboratory  and  office  space  at  2488  Dunwin  Drive,  Mississauga,  Ontario,  Canada,  L5L  1J9  and
approximately  3,200  square  feet  of  leased  office  space  at  100  Cambridge  Park  Drive,  Cambridge,  Massachusetts,  USA,  02140.  We  perform  research  and
development in our facility and use qualified vendors and collaborators to conduct research and development and manufacturing on our behalf. We incur capital
expenditures mainly for laboratory equipment, office equipment, computer equipment and leaseholds in the operation of our business.

Employees

As at December 31, 2019, we had twenty-nine full-time employees including six senior management, seventeen research and development staff and six finance and
administrative staff. Twenty-five employees were located at our office and lab facilities in Mississauga, Ontario, Canada and four employees were located at our
office in Cambridge, Massachusetts, United States.

We also use consultants and outside contractors to carry on many of our activities, including preclinical testing and validation, formulation, assay development,
manufacturing, clinical and regulatory affairs, toxicology and clinical trials.

Legal Proceedings

To  our  knowledge,  there  have  not  been  any  legal  or  arbitration  proceedings,  including  those  relating  to  bankruptcy,  receivership  or  similar  proceedings,  those
involving any third party, and governmental proceedings pending or known to be contemplated, which may have, or have had in the recent past, significant effect
on our financial position or profitability.

Also, to our knowledge, there have been no material proceedings in which any director, any member of senior management, or any of our affiliates is either a party
adverse to us or any of our subsidiaries or has a material interest adverse to us or any of our subsidiaries.

Capital Expenditures

Capital expenditures for 2019 were mainly for the capitalization of building operating leases under IFRS 16 and leasehold improvements for our new Cambridge
office.  Capital expenditures for 2018 were mainly for laboratory equipment and computer equipment. Capital expenditures in the years ended December 31, 2019
and 2018 are set out in the following table.

Trend Information

Historical  patterns  of  expenditures  cannot  be  taken  as  an  indication  of  future  expenditures.  The  amount  and  timing  of  expenditures  and  therefore  liquidity  and
capital resources vary substantially from period to period depending on the number of research and development programs being undertaken at any one time, the
stage  of  the  development  programs,  the  timing  of  significant  expenditures  for  manufacturing,  toxicology  and  pharmacology  studies  and  clinical  trials,  and  the
availability of funding from investors and prospective commercial partners.

The following information sets forth material risks and uncertainties that may affect our business, including our future financing and operating results and could
cause our actual results to differ materially from those contained in forward-looking statements we have made in this AIF. The risks and uncertainties below are
not the only ones we face. Additional risks and uncertainties not presently known to us or that we believe to be immaterial may also adversely affect our business.
Further, if we fail to meet the expectations of the public market in any given period, the market price of our common shares could decline. We operate in a highly
competitive environment that involves significant risks and uncertainties, some of which are outside of our control.

RISK FACTORS

Risks Related to Our Financial Position and Need for Additional Capital

We expect to incur future losses and we may never become profitable.

We have incurred losses of $41,622, $32,866 and $35,225 for the years ended December 31, 2019, 2018 and 2017, respectively, and expect to incur an operating
loss for the year ending December 31, 2020. We have an accumulated deficit since inception through December 31, 2019 of $190,999. We believe that operating
losses will continue as we are planning to incur significant costs associated with the clinical development of our SIRPαFc molecules. Our net losses have had and
will continue to have an adverse effect on, among other things, our shareholders' equity, total assets and working capital. We expect that losses will fluctuate from
quarter to quarter and year to year, and that such fluctuations may be substantial. We cannot predict when we will become profitable, if at all.

We will require additional capital to finance our operations, which may not be available to us on acceptable terms, or at all. As a result, we may not complete
the development and commercialization of our product candidates or develop new product candidates.

As  a  research  and  development  company,  our  operations  have  consumed  substantial  amounts  of  cash  since  inception.  We  expect  to  spend  substantial  funds  to
continue the research, development and testing of our product candidates and to prepare to commercialize products subject to approval of the FDA, in the US and
similar  approvals  in  other  jurisdictions.  We  will  also  require  significant  additional  funds  if  we  expand  the  scope  of  our  current  clinical  plans  or  if  we  were  to
acquire  any  new  assets  and  advance  their  development.  Therefore,  for  the  foreseeable  future,  we  will  have  to  fund  all  of  our  operations  and  development
expenditures from cash on hand, equity or debt financings, through collaborations  with other biotechnology or pharmaceutical  companies or through financings
from other sources. We expect that our existing combined cash and cash equivalents and marketable securities as at December 31, 2019 of $22,666, together with
the  gross  proceeds  of  $116,995  related  to  the  completion  of  an  underwritten  public  offering  in  January  2020,  will  enable  us  to  fund  our  current  operating  plan
requirements for at least the next twelve months. Additional financing will be required to meet our longer term liquidity needs. If we do not succeed in raising
additional  funds  on  acceptable  terms,  we  might  not  be  able  to  complete  preclinical  studies  and  clinical  trials  or  pursue  and  obtain  approval  of  any  product
candidates from the FDA and other regulatory authorities. It is possible that future financing will not be available or, if available, may not be on favorable terms.
The availability of financing will be affected by the achievement of our corporate goals, the results of scientific and clinical research, the ability to obtain regulatory
approvals, the state of the capital markets generally and with particular reference to drug development companies, the status of strategic alliance agreements and
other  relevant  commercial  considerations.  If  adequate  funding  is  not  available,  we  may  be  required  to  delay,  reduce  or  eliminate  one  or  more  of  our  product
development  programs,  or  obtain  funds  through  corporate  partners  or  others  who may  require  us  to  relinquish  significant  rights  to  product  candidates  or  obtain
funds on less favorable terms than we would otherwise accept. To the extent that external sources of capital become limited or unavailable or available on onerous
terms, our intangible assets and our ability to continue our clinical development plans may become impaired, and our assets, liabilities, business, financial condition
and results of operations may be materially or adversely affected.

We currently have no product revenue and will not be able to maintain our operations and research and development without additional funding.

To  date,  we  have  generated  no  product  revenue  and  cannot  predict  when  and  if  we  will  generate  product  revenue.  Our  ability  to  generate  product  revenue  and
ultimately  become  profitable  depends  upon  our  ability,  alone  or  with  partners,  to  successfully  develop  our  product  candidates,  obtain  regulatory  approval,  and
commercialize products, including any of our current product candidates, or other product candidates that we may develop, in-license or acquire in the future. We
do  not  anticipate  generating  revenue  from  the  sale  of  products  for  the  foreseeable  future.  We  expect  our  research  and  development  expenses  to  increase  in
connection with our ongoing activities, particularly as we advance our product candidates through clinical trials.

19

We may be subject to significant cash payouts in connection with our outstanding warrants in the event of a "Fundamental Transaction".

In  the  event  of  a  "Fundamental  Transaction"  (as  defined  in  the  related  warrant  agreement,  which  generally  includes  any  merger  with  another  entity,  the  sale,
transfer or other disposition of all or substantially all of our assets to another entity, or the acquisition by a person of more than 50% of our common stock), each
warrant holder will have the right up to 90 days after the consummation of the Fundamental Transaction to require us to repurchase the warrant for a purchase price
in cash equal to the Black Scholes value (as calculated under the warrant agreement) of the then remaining unexercised portion of such warrant on the date of such
Fundamental Transaction, which may materially adversely affect our financial condition and/or results of operations. There can be no assurance that in the event of
a Fundamental Transaction we will be able to sufficiently compensate the holders of the warrants in accordance with the terms thereof. The warrant provisions may
delay or prevent our ability to undertake a strategic transaction that may be beneficial to shareholders. These restrictions may also adversely affect the market price
of our common shares.

We are exposed to the financial risk related to the fluctuation of foreign exchange rates and the degrees of volatility of those rates.

We may be adversely affected by foreign currency fluctuations. To date, we have been primarily funded through issuances of equity, proceeds from the exercise of
warrants and stock options and from interest income on funds available for investment, which are denominated both in Canadian and US dollars. Also, a significant
portion of our expenditures are in US dollars, and we are therefore subject to foreign currency fluctuations which may, from time to time, impact our financial
position and results of operations.

Risks Related to Our Business and Our Industry

Our prospects depend on the success of our product candidates which are at early stages of development, and we may not generate revenue for several years, if
at all, from these products.

Given the early stage of our product development, we can make no assurance that our research and development programs will result in regulatory approval or
commercially  viable  products.  To  achieve  profitable  operations,  we,  alone  or  with  others,  must  successfully  develop,  gain  regulatory  approval,  and  market  our
future  products.  We  currently  have  no  products  that  have  been  approved  by  the  FDA,  Health  Canada,  or  HC,  or  any  similar  regulatory  authority.  To  obtain
regulatory approvals for our product candidates being developed and to achieve commercial success, clinical trials must demonstrate that the product candidates are
safe for human use and that they demonstrate efficacy. While we have commenced clinical trials for SIRPαFc, we have not yet completed later stage clinical trials
for any of our product candidates.

Many product candidates never reach the stage of clinical testing and even those that do have only a small chance of successfully completing clinical development
and gaining regulatory approval. Product candidates may fail for a number of reasons, including, but not limited to, being unsafe for human use or due to the failure
to provide therapeutic benefits equal to or better than the standard of treatment at the time of testing. Unsatisfactory results obtained from a particular study relating
to a research and development program may cause us or our collaborators to abandon commitments to that program.

The early stage of our product development makes it particularly uncertain whether any of our product development efforts will prove to be successful and meet
applicable regulatory requirements, and whether any of our product candidates will receive the requisite regulatory approvals, be capable of being manufactured at
a reasonable cost or be successfully marketed. If we are successful in developing our current and future product candidates into approved products, we will still
experience many potential obstacles such as the need to develop or obtain manufacturing, marketing and distribution capabilities. If we are unable to successfully
commercialize any of our products, our financial condition and results of operations may be materially and adversely affected.

20

Positive results from preclinical and early clinical research of TTI-621 and TTI-622 are not necessarily predictive of the results of later clinical trials of TTI-
621  or  TTI-622.  If  we  cannot  replicate  the  positive  results  from  preclinical  and  early  clinical  research  in  our  later  clinical  trials,  we  may  be  unable  to
successfully develop, obtain regulatory approval for and commercialize TTI-621 or TTI-622.

Positive results of preclinical and early clinical research of TTI-621 and TTI-622 may not be indicative of the results that will be obtained in later-stage clinical
trials.  For  example,  we  have  focused  our  near-term  clinical  product  development  on  T-cell  malignancies  based  on  preliminary  results  of  our  intravenous  and
intratumoral trials. There can be no assurance that the preliminary results we have seen in a small number of T-cell lymphoma patients will be reproducible in a
larger population of patients. We can make no assurance that any future studies, if undertaken, will yield favorable results.

Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later-stage clinical trials after achieving positive results
in early-stage development, and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things, preclinical
findings  made  while  clinical  trials  were  underway  or  safety  or  efficacy  observations  made  in  clinical  trials,  including  previously  unreported  adverse  events.
Moreover, preclinical  and clinical data are often susceptible to varying interpretations  and analyses, and many companies that believed their product candidates
performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA approval. If we fail to produce positive results in our clinical trials
of  TTI-621  or  TTI-622,  the  development  timeline  and  regulatory  approval  and  commercialization  prospects  for  our  leading  product  candidates,  and,
correspondingly, our business and financial prospects, would be materially adversely affected.

We  rely  and  will  continue  to  rely  on  third  parties  to  plan,  conduct  and  monitor  our  preclinical  studies  and  clinical  trials,  and  their  failure  to  perform  as
required could cause substantial harm to our business.

We rely and will continue to rely on third parties to conduct a significant portion of our preclinical and clinical development activities. Preclinical activities include
in vivo studies providing access to specific disease models, pharmacology and toxicology studies, and assay development. Clinical development activities include
trial design, regulatory submissions, clinical patient and site recruitment, clinical trial monitoring, clinical data management and analysis, safety monitoring and
project management. If there is any dispute or disruption in our relationship with third parties, or if they are unable to provide quality services in a timely manner
and at a feasible cost, our active development programs will face delays. Further, if any of these third parties fails to perform as we expect or if their work fails to
meet regulatory requirements, our testing could be delayed, cancelled or rendered ineffective.

We rely  on contract  manufacturers  over whom we have limited  control. If we are subject  to quality,  cost or delivery  issues with the preclinical  and clinical
grade materials supplied by contract manufacturers, our business operations could suffer significant harm.

We have limited manufacturing experience and rely on contract manufacturing organizations, or CMOs to manufacture our product candidates for larger preclinical
studies  and  clinical  trials.  We  rely  on  CMOs  for  manufacturing,  filling,  packaging,  storing  and  shipping  of  drug  product  in  compliance  with  current  Good
Manufacturing  Practice,  or  cGMP,  regulations  applicable  to  our  products.  The  FDA  ensures  the  quality  of  drug  products  by  carefully  monitoring  drug
manufacturers' compliance with cGMP regulations. The cGMP regulations for drugs contain minimum requirements for the methods, facilities and controls used in
manufacturing, processing and packaging of a drug product.

We contracted with Catalent for the manufacture of the SIRPαFc protein to supply drug substance for our clinical trials. The manufacture of recombinant proteins
uses  well  established  processes  including  a  protein  expression  system.  Catalent  is  producing  SIRPαFc  using  their  proprietary  GPEx®  expression  system.  We
believe that Catalent has the capacity, the systems, and the experience to supply SIRPαFc for our current clinical trials and we may consider using Catalent for
manufacturing  for  later  clinical  trials.  However,  since  the  Catalent  manufacturing  facility  where  SIRPαFc  is  being  produced  does  not  support  commercial
manufacturing, it has not yet been inspected by the FDA. Any manufacturing failures, delays or compliance issues could cause delays in the conduct of SIRPαFc
preclinical studies and clinical trials.

21

There can be no assurances that CMOs will be able to meet our timetable  and requirements. We have not contracted with alternate  suppliers for SIRPαFc drug
substance production in the event Catalent is unable to scale up production, or if Catalent otherwise experiences any other significant problems. If we are unable to
arrange for alternative third-party manufacturing sources on commercially reasonable terms or in a timely manner, we may be delayed in the development of our
product  candidates.  Further,  CMOs  must  operate  in  compliance  with  cGMP  and  failure  to  do  so  could  result  in,  among  other  things,  the  disruption  of  product
supplies. Our dependence upon third parties for the manufacture  of our products may adversely affect our profit margins and our ability to develop and deliver
products on a timely and competitive basis.

We require commercial scale and quality manufactured product to be available for pivotal or registration clinical trials. If we do not have commercial grade
drug supply when needed, we may face delays in initiating or completing pivotal trials and our business operations could suffer significant harm.

To date, our product has been manufactured in small quantities for preclinical studies and clinical trials by third-party manufacturers. In order to commercialize our
product,  we  need  to manufacture  commercial  quality  drug  supply  for use  in  registration  clinical  trials.  Most,  if not  all,  of  the  clinical  material  used  in  phase  3/
pivotal/ registration studies must be derived from the defined commercial process including scale, manufacturing site, process controls and batch size. If we have
not  scaled  up  and  validated  the  commercial  production  of  our  product  prior  to  the  commencement  of  pivotal  clinical  trials,  we may  have  to  employ  a  bridging
strategy during the trial to demonstrate equivalency of early stage material to commercial drug product, or potentially delay the initiation or completion of the trial
until  drug  supply  is  available.  The  manufacturing  of  commercial  quality  drug  product  requires  significant  efforts  including,  but  not  limited  to  scale-up  of
production to anticipated commercial scale, process characterization and validation, analytical method validation, identification of critical process parameters and
product quality attributes, multiple process performance and validation runs, has long lead times and is very expensive. If we do not have commercial drug supply
available when needed for pivotal clinical trials, our regulatory and commercial progress may be delayed and we may incur increased product development cost.
This may have a material adverse effect on our business, financial condition and prospects, and may delay marketing of the product.

If  clinical  trials  of  our  product  candidates  fail  to  demonstrate  safety  and  efficacy  to  the  satisfaction  of  regulatory  authorities  or  do  not  otherwise  produce
positive  results,  we  would  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the  development  and
commercialization of our product candidates.

Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  our  product  candidates,  we  must  conduct  preclinical  studies  in  animals  and
extensive  clinical  trials  in  humans  to  demonstrate  the  safety  and  efficacy  of  the  product  candidates.  Clinical  testing  is  expensive  and  difficult  to  design  and
implement, can take many years to complete and has uncertain outcomes. The outcome of preclinical studies and early clinical trials may not predict the success of
later clinical trials, and interim results of a clinical trial do not necessarily predict final results. A number of companies in the pharmaceutical and biotechnology
industries have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety profiles, notwithstanding promising results in
earlier trials. We do not know whether the clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market
any of our product candidates in any jurisdiction. A product candidate may fail for safety or efficacy reasons at any stage of the testing process. A major risk we
face is the possibility that none of our product candidates under development will successfully gain market approval from the FDA or other regulatory authorities,
resulting in us being unable to derive any commercial revenue from them after investing significant amounts of capital in their development.

If we experience delays in clinical testing, we will be delayed in commercializing our product candidates, and our business may be substantially harmed.

We  cannot  predict  whether  any  clinical  trials  will  begin  as  planned,  will  need  to  be  restructured,  or  will  be  completed  on  schedule,  or  at  all.  Our  product
development costs will increase if we experience delays in clinical testing. Significant clinical trial delays could shorten any periods during which we may have the
exclusive  right  to  commercialize  our  product  candidates  or  allow  our  competitors  to  bring  products  to  market  before  us,  which  would  impair  our  ability  to
successfully commercialize our product candidates and may harm our financial condition, results of operations and prospects. The commencement and completion
of clinical trials for our products may be delayed for a number of reasons, including delays related, but not limited, to:

22

failure by regulatory authorities to grant permission to proceed or placing the clinical trial on hold;
patients failing to enroll or remain in our trials at the rate we expect;
suspension or termination of clinical trials by regulators for many reasons, including concerns about patient safety or failure of our CMOs to comply with
cGMP requirements;
any changes to our manufacturing process that may be necessary or desired;
delays or failure to obtain clinical supply from CMOs of our products necessary to conduct clinical trials;
product candidates demonstrating a lack of safety or efficacy during clinical trials;
patients choosing an alternative treatment for the indications for which we are developing any of our product candidates or participating in competing
clinical trials;
patients failing to complete clinical trials due to dissatisfaction with the treatment, side effects or other reasons;
reports of clinical testing on similar technologies and products raising safety and/or efficacy concerns;
competing clinical trials and scheduling conflicts with participating clinicians;
clinical investigators not performing our clinical trials on their anticipated schedule, dropping out of a trial, or employing methods not consistent with the
clinical trial protocol, regulatory requirements or other third parties not performing data collection and analysis in a timely or accurate manner;
failure of our contract research organizations, or CROs, to satisfy their contractual duties or meet expected deadlines;
inspections of clinical trial sites by regulatory authorities or Institutional Review Boards, or IRBs, or ethics committees finding regulatory violations that
require us to undertake corrective action, resulting in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study;
one or more IRBs or ethics committees rejecting, suspending or terminating the study at an investigational site, precluding enrollment of additional
subjects, or withdrawing its approval of the trial; or
failure to reach agreement on acceptable terms with prospective clinical trial sites.

Our product development costs will increase if we experience delays in testing or approval or if we need to perform more or larger clinical trials than planned.
Additionally, changes in regulatory requirements and policies may occur, and we may need to amend study protocols to reflect these changes. Amendments may
require  us  to  resubmit  our  study  protocols  to  regulatory  authorities  or  IRBs  or  ethics  committees  for  re-examination,  which  may  impact  the  cost,  timing  or
successful  completion  of  that  trial.  Delays  or  increased  product  development  costs  may  have  a  material  adverse  effect  on  our  business,  financial  condition  and
prospects.

We may not achieve our publicly announced milestones according to schedule, or at all.

From  time  to  time,  we  may  announce  the  timing  of  certain  events  we  expect  to  occur,  such  as  the  anticipated  timing  of  results  from  our  clinical  trials.  These
statements are forward-looking and are based on the best estimates of management at the time relating to the occurrence of such events. However, the actual timing
of such events may differ from what has been publicly disclosed. The timing of events such as initiation or completion of a clinical trial, filing of an application to
obtain  regulatory  approval,  or  announcement  of  additional  clinical  trials  for  a  product  candidate  may  ultimately  vary  from  what  is  publicly  disclosed.  These
variations in timing may occur as a result of different events, including the nature of the results obtained during a clinical trial or during a research phase, timing of
the completion of clinical trials, problems with a CMO or a CRO or any other event having the effect of delaying the publicly announced timeline. We undertake
no obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, except as otherwise required
by law. Any variation in the timing of previously announced milestones could have a material adverse effect on our business plan, financial condition or operating
results and the trading price of our common shares.

We may not be able to file INDs to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to
proceed in a timely manner, or at all.

Prior to commencing clinical trials in the United States for any of our product candidates, we may be required to have an allowed IND for each product candidate
and to file additional INDs prior to initiating any additional clinical trials for SIRPαFc. We believe that the data from previous studies will support the filing of
additional INDs, to enable us to undertake additional clinical studies as we have planned. However, submission of an IND may not result in the FDA allowing
further  clinical  trials  to  begin  and,  once  begun,  issues  may  arise  that  will  require  us  to  suspend  or  terminate  such  clinical  trials.  Additionally,  even  if  relevant
regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND, these regulatory authorities may change their requirements
in the future. Failure to submit or have effective INDs and commence or continue clinical programs will significantly limit our opportunity to generate revenue.

23

If we have difficulty enrolling patients in clinical trials, the completion of the trials may be delayed or cancelled.

As our product candidates advance from preclinical testing to clinical testing, and then through progressively larger and more complex clinical trials, we will need
to enroll an increasing number of patients that meet our eligibility criteria. There is significant competition for recruiting cancer patients in clinical trials, and we
may be unable to enroll the patients we need to complete clinical trials on a timely basis or at all. The factors that affect our ability to enroll patients are largely
uncontrollable and include, but are not limited to, the following:

size and nature of the patient population;
eligibility and exclusion criteria for the trial;
design of the study protocol;
competition with other companies for clinical sites or patients;
the perceived risks and benefits of the product candidate under study;
the patient referral practices of physicians; and
the number, availability, location and accessibility of clinical trial sites.

If we are unable to successfully develop companion diagnostics for our therapeutic product candidates, or experience significant delays in doing so, we may not
achieve marketing approval or realize the full commercial potential of our therapeutic product candidates.

We  may  develop  companion  diagnostics  for  our  therapeutic  product  candidates.  We  expect  that,  at  least  in  some  cases,  regulatory  authorities  may  require  the
development and regulatory approval of a companion diagnostic as a condition to approving our therapeutic product candidates. We have limited experience and
capabilities in developing or commercializing diagnostics and plan to rely in large part on third parties to perform these functions. We have not begun to develop
companion diagnostics for any of our therapeutic product candidates.

Companion  diagnostics  are  subject  to  regulation  by  the  FDA,  HC,  and  comparable  foreign  regulatory  authorities  as  medical  devices  and  may  require  separate
regulatory approval or clearance prior to commercialization. If we, or any third parties that we engage to assist us, are unable to successfully develop companion
diagnostics for our therapeutic product candidates, or experience delays in doing so, our business may be substantially harmed.

Regulatory  approval  processes  are  lengthy,  expensive  and  inherently  unpredictable.  Our  inability  to  obtain  regulatory  approval  for  our  product  candidates
would substantially harm our business.

Our development and commercialization activities and product candidates are significantly regulated by a number of governmental entities, including the FDA,
HC, and comparable authorities in other countries. Regulatory approvals are required prior to each clinical trial and we may fail to obtain the necessary approvals to
commence  or  continue  clinical  testing.  We  must  comply  with  regulations  concerning  the  manufacture,  testing,  safety,  effectiveness,  labeling,  documentation,
advertising, and sale of products and product candidates and ultimately must obtain regulatory approval before we can commercialize a product candidate. The time
required to obtain approval by such regulatory authorities is unpredictable but typically takes many years following the commencement of preclinical studies and
clinical trials. Any analysis of data from clinical activities we perform is subject to confirmation and interpretation by regulatory authorities, which could delay,
limit or prevent regulatory approval. Even if we believe results from our clinical trials are favorable to support the marketing of our product candidates, the FDA or
other regulatory authorities may disagree. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change
during  the  course  of  a  product  candidate's  clinical  development  and  may  vary  among  jurisdictions.  We  have  not  obtained  regulatory  approval  for  any  product
candidate and it is possible that none of our existing product candidates or any future product candidates will ever obtain regulatory approval.

24

We could fail to receive regulatory approval for our product candidates for many reasons, including, but not limited to:

disagreement with the design or implementation of our clinical trials;
failure to demonstrate that a product candidate is safe and effective for its proposed indication;
failure of clinical trials to meet the level of statistical significance required for approval;
failure to demonstrate that a product candidate's clinical and other benefits outweigh its safety risks;
disagreement with our interpretation of data from preclinical studies or clinical trials;
the insufficiency of data collected from clinical trials of our product candidates to support the submission and filing of a biologic license application, or
BLA, or other submission to obtain regulatory approval;
deficiencies in the manufacturing processes or the failure of facilities of CMOs with whom we contract for clinical and commercial supplies to pass a pre-
approval inspection; or
changes in the approval policies or regulations that render our preclinical and clinical data insufficient for approval.

A regulatory authority may require more information, including additional preclinical or clinical data to support approval, which may delay or prevent approval and
our commercialization plans, or we may decide to abandon the development program. If we were to obtain approval, regulatory authorities may approve any of our
product candidates for fewer or more limited indications than we request, may grant approval contingent on the performance of costly post-marketing clinical trials,
or  may  approve  a  product  candidate  with  a  label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that
product candidate. Moreover, depending on any safety issues associated with our product candidates that garner approval, the FDA may impose a risk evaluation
and mitigation strategy, thereby imposing certain restrictions on the sale and marketability of such products.

We face competition from other biotechnology and pharmaceutical companies and our financial condition and operations will suffer if we fail to effectively
compete.

The  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant  technological  change.  Our  competitors  include
large, well-established pharmaceutical companies, biotechnology companies, and academic and research institutions developing cancer therapeutics for the same
indications we are targeting and competitors with existing marketed therapies. Many other companies are developing or commercializing therapies to treat the same
diseases or indications for which our product candidates may be useful. Although there are no approved therapies that specifically target the CD47 pathway, some
competitors use therapeutic approaches that may compete directly with our product candidates. For example, SIRPαFc is in direct competition with CD47 blocking
antibodies from Forty Seven Inc., Celgene Corporation, TG Therapeutics and others.

Many  of  our  competitors  have  substantially  greater  financial,  technical  and  human  resources  than  we  do  and  have  significantly  greater  experience  than  us  in
conducting preclinical testing and human clinical trials of product candidates, scaling up manufacturing operations and obtaining regulatory approvals of products.
Accordingly, our competitors may succeed in obtaining regulatory approval for products more rapidly than we do. Our ability to compete successfully will largely
depend on:

the efficacy and safety profile of our product candidates relative to marketed products and other product candidates in development;
our ability to develop and maintain a competitive position in the product categories and technologies on which we focus;
the time it takes for our product candidates to complete clinical development and receive marketing approval;
our ability to obtain required regulatory approvals;
our ability to commercialize any of our product candidates that receive regulatory approval;
our ability to establish, maintain and protect intellectual property rights related to our product candidates; and
acceptance of any of our product candidates that receive regulatory approval by physicians and other healthcare providers and payers.

25

If we are not able to compete effectively against our current and future competitors, our business will not grow and our financial condition and operations will
substantially suffer.

We  heavily  rely  on  the  capabilities  and  experience  of  our  key  executives  and  scientists  and  the  loss  of  any  of  them  could  affect  our  ability  to  develop  our
products.

Our  success  will  depend  in  large  measure  on  the  ability,  expertise,  judgement,  discretion,  integrity  and  good  faith  of  our  key  executives  and  other  personnel
conducting  our  business.  Our  management  structure  has  undergone  changes  in  2019  due  to  the  resignation  in  April  2019  of  our  former  President  and  Chief
Executive Officer and director, and the appointment in September 2019 of our new President and Chief Executive Officer and director, Dr. Jan Skvarka. Dr. Robert
L. Kirkman, M.D., the Chair of the Board is currently acting as Executive Chair, and Dr. Robert Uger, the current Chief Scientific Officer, served as a director from
April 30, 2019 to February 6, 2020. We have employment agreements with Dr. Skvarka, Dr. Kirkman and Dr. Uger, and other key members of our staff, and in
May 2019 the Board put agreements in place for key executives and staff to encourage retention, although such agreements do not guarantee their retention. This
transition may cause some disruption to our business, and may have an adverse effect on our business, operating results or financial condition.

We also depend on our scientific and clinical collaborators and advisors, all of whom have outside commitments that may limit their availability to us. In addition,
we  believe  that  our  future  success  will  depend  in  large  part  upon  our  ability  to  attract  and  retain  highly  skilled  scientific,  managerial,  medical,  manufacturing,
clinical, commercial and regulatory personnel, particularly as we expand our activities and seek regulatory approvals for clinical trials. We enter into agreements
with our scientific and clinical collaborators and advisors, key opinion leaders and academic partners in the ordinary course of our business. We also enter into
agreements with physicians and institutions who will recruit patients into our clinical trials on our behalf in the ordinary course of our business. Notwithstanding
these arrangements, we face significant competition for these types of personnel from other companies, research and academic institutions, government entities and
other  organizations.  We  cannot  predict  our  success  in  hiring  or retaining  the  personnel  we require  for  continued  growth.  The  loss  of  the  services  of  any  of  our
executive officers or other key personnel could potentially harm our business, operating results or financial condition.

Our  employees  may  engage  in  misconduct  or  other  improper  activities,  including  noncompliance  with  regulatory  standards  and  requirements,  which  could
have a material adverse effect on our business.

We  are  exposed  to  the  risk  of  employee  fraud  or  other  misconduct.  Misconduct  by  employees  could  include  failures  to  comply  with  FDA  regulations,  provide
accurate information to the FDA, comply with manufacturing standards we have established, comply with federal and state healthcare fraud and abuse laws and
regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the
healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing, and other abusive practices. These laws and
regulations  may  restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,  sales  commission,  customer  incentive  programs  and  other
business arrangements.  Employee  misconduct  could also involve  the improper  use of information  obtained in the course  of clinical  trials,  which could result  in
regulatory sanctions and serious harm to our reputation. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting
our rights, those actions could have a substantial impact on our business and results of operations, including the imposition of substantial fines or other sanctions.

We may expand our business through the acquisition of companies or businesses or by entering into collaborations or by in-licensing product candidates, each
of which could disrupt our business and harm our financial condition.

We  have  in  the  past  and  may  in  the  future  seek  to  expand  our  pipeline  and  capabilities  by  acquiring  one  or  more  companies  or  businesses,  entering  into
collaborations, or in-licensing one or more product candidates. Acquisitions, collaborations and in-licenses involve numerous risks, including, but not limited to:

substantial cash expenditures;
technology development risks;
potentially dilutive issuances of equity securities;

26

incurrence of debt and contingent liabilities, some of which may be difficult or impossible to identify at the time of acquisition;
difficulties in assimilating the operations of the acquired companies;
potential disputes regarding contingent consideration;
diverting our management's attention away from other business concerns;
entering markets in which we have limited or no direct experience; and
potential loss of our key employees or key employees of the acquired companies or businesses.

We  have  experience  in  making  acquisitions,  entering  collaborations,  and  in-licensing  product  candidates,  however,  we  cannot  provide  assurance  that  any
acquisition, collaboration or in-license will result in short-term or long-term benefits to us. We may incorrectly judge the value or worth of an acquired company or
business or in-licensed product candidate. In addition, our future success would depend in part on our ability to manage the rapid growth associated with some of
these acquisitions, collaborations and in-licenses. We cannot provide assurance that we would be able to successfully combine our business with that of acquired
businesses,  manage  a  collaboration  or  integrate  in-licensed  product  candidates.  Furthermore,  the  development  or  expansion  of  our  business  may  require  a
substantial capital investment by us.

Negative results from clinical  trials or studies of others and adverse safety events involving the targets of our products may have an adverse impact on our
future commercialization efforts.

From time to time, studies or clinical trials on various aspects of biopharmaceutical products are conducted by academic researchers, competitors or others. The
results of these studies or trials, when published, may have a significant effect on the market for the biopharmaceutical product that is the subject of the study. The
publication of negative results of studies or clinical trials or adverse safety events related to our product candidates, or the therapeutic areas in which our product
candidates compete, could adversely affect our share price and our ability to finance future development of our product candidates, and our business and financial
results could be materially and adversely affected.

We face the risk of product liability claims, which could exceed our insurance coverage and produce recalls, each of which could deplete our cash resources.

We are exposed to the risk of product liability claims alleging that use of our product candidates caused an injury or harm. These claims can arise at any point in the
development,  testing,  manufacture,  marketing  or  sale  of  our  product  candidates  and  may  be  made  directly  by  patients  involved  in  clinical  trials  of  our  product
candidates, by consumers or healthcare providers or by individuals, organizations or companies selling our products. Product liability claims can be expensive to
defend, even if the product or product candidate did not actually cause the alleged injury or harm.

Insurance covering product liability claims becomes increasingly expensive as a product candidate moves through the development pipeline to commercialization.
We currently maintain clinical trial liability insurance coverage of $10,000. However, there can be no assurance that such insurance coverage is or will continue to
be adequate or available to us at a cost acceptable to us or at all. We may choose or find it necessary under our collaborative agreements to increase our insurance
coverage  in  the  future.  We  may  not  be  able  to  secure  greater  or  broader  product  liability  insurance  coverage  on  acceptable  terms  or  at  reasonable  costs  when
needed. Any liability for damages resulting from a product liability claim could exceed the amount of our coverage, require us to pay a substantial monetary award
from  our  own  cash  resources  and  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  Moreover,  a  product  recall,  if
required,  could  generate  substantial  negative  publicity  about  our  products  and  business,  inhibit  or  prevent  commercialization  of  other  products  and  product
candidates or negatively impact existing or future collaborations.

If we are unable to maintain product liability insurance required by our third parties, the corresponding agreements would be subject to termination, which
could have a material adverse impact on our operations.

Some of our licensing and other agreements with third parties require or might require us to maintain product liability insurance. If we cannot maintain acceptable
amounts of coverage on commercially reasonable terms in accordance with the terms set forth in these agreements, the corresponding agreements would be subject
to termination, which could have a material adverse impact on our operations.

27

Risks Related to Intellectual Property

If  we  are  unable  to  adequately  protect  and  enforce  our  intellectual  property,  our  competitors  may  take  advantage  of  our  development  efforts  or  acquired
technology and compromise our prospects of marketing and selling our key products.

We control two main patent families relating to SIRPα. One family relates to the use of SIRPα to treat cancer. The other family relates to our drug as a composition
of matter, SIRPαFc. We have also filed for patent protection covering additional inventions relating to SIRPα, including anti-cancer drug combination therapies
that utilize SIRPαFc, and biomarkers that identify SIRPαFc responders. Our success will depend in part upon our ability to protect our intellectual property and
proprietary  technologies  and  upon  the  nature  and  scope  of  the  intellectual  property  protection  we  receive.  For  example,  some  of  our  patent  portfolio  covers
primarily  methods  of  medical  use  but  not  compositions  of  matter.  The  ability  to  compete  effectively  and  to  achieve  partnerships  will  depend  on  our  ability  to
develop and maintain proprietary aspects of our technology and to operate without infringing on the proprietary rights of others. The presence of such proprietary
rights of others could severely limit our ability to develop and commercialize our products, to conduct our existing research and could require financial resources to
defend litigation, which may be in excess of our ability to raise such funds. There is no assurance that our pending patent applications or any that we intend to
acquire will be approved in a form that will be sufficient to protect our proprietary technology and gain or keep any competitive advantage that we may have or,
once approved, will be upheld in any post-grant proceedings brought by any third parties.

The patent positions of pharmaceutical companies can be highly uncertain and involve complex legal, scientific and factual questions for which important legal
principles  remain  unresolved.  Patents  issued  to  us  or  our  respective  licensors  may  be  challenged,  invalidated  or  circumvented.  To  the  extent  our  intellectual
property, including licensed intellectual property, offers inadequate protection, or is found to be invalid or unenforceable, we are exposed to a greater risk of direct
competition.  If  our  intellectual  property  does  not  provide  adequate  protection  against  our  competitors'  products,  our  competitive  position  could  be  adversely
affected, as could our business, financial condition and results of operations. Both the patent application process and the process of managing patent disputes can be
time consuming and expensive, and the laws of some foreign countries may not protect our intellectual property rights to the same extent as do the laws of Canada
and the United States.

We will be able to protect our intellectual property from unauthorized use by third parties only to the extent that our proprietary technologies, key products, and any
future products are covered by valid and enforceable intellectual property rights including patents or are effectively maintained as trade secrets, and provided we
have the funds to enforce our rights, if necessary.

If we lose our licenses from third-party owners we may be unable to continue a substantial part of our business.

We are party to licenses that give us rights to intellectual property that is necessary or useful for a substantial part of our business. Pursuant to our exclusive license
agreement with the University Health Network and the Hospital for Sick Children under which we license certain patent rights for our key products and their uses,
we are required to use commercially reasonable efforts to commercialize products based on the licensed rights and pay milestone payments, royalties on net sales,
and an annual maintenance fee.

We  have  also  entered  into  agreements  allowing  us  to  manufacture  SIRPαFc using  Catalent's  proprietary  GPEx®  expression  system.  The  consideration  includes
payments at the time we successfully reach a series of development and sales milestones. We may also enter into licenses in the future to access additional third-
party intellectual property.

If  we  fail  to  pay  annual  maintenance  fees,  development  and  sales  milestones,  or  it  is  determined  that  we  did  not  use  commercially  reasonable  efforts  to
commercialize licensed products, we could lose our licenses which could have a material adverse effect on our business and financial condition.

We may require additional third-party licenses to effectively develop and manufacture our key products and are currently unable to predict the availability or
cost of such licenses.

28

A substantial number of patents have already been issued to other biotechnology and pharmaceutical companies. To the extent that valid third-party patent rights
cover our products or services, we or our strategic collaborators would be required to seek licenses from the holders of these patents in order to manufacture, use or
sell these products and services, and payments under them would reduce our profits from these products and services. We are currently unable to predict the extent
to which we may wish or be required to acquire rights under such patents, the availability and cost of acquiring such rights, and whether a license to such patents
will be available on acceptable terms or at all. There may be patents in the US or in foreign countries or patents issued in the future that are unavailable to license
on acceptable terms. Our inability to obtain such licenses may hinder or eliminate our ability to manufacture and market our products.

Changes in patent law and its interpretation could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

As  is  the  case  with  other  biotechnology  and  pharmaceutical  companies,  our  success  is  heavily  dependent  on  intellectual  property  rights,  particularly  patents.
Obtaining  and  enforcing  patents  in  the  biopharmaceutical  industry  involves  technological  and  legal  complexity,  and  obtaining  and  enforcing  biopharmaceutical
patents is costly, time-consuming and inherently uncertain. The US Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of
patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard
to  our  and  our  licensors'  or  collaborators'  ability  to  obtain  patents  in  the  future,  this  combination  of  events  has  created  uncertainty  with  respect  to  the  value  of
patents,  once  obtained.  Depending  on  decisions  by  the  US  Congress,  the  federal  courts,  and  the  US  Patent  and  Trademark  Office,  or  USPTO,  the  laws  and
regulations governing patents could change in unpredictable  ways that would weaken our and our licensors' or collaborators'  ability to obtain new patents or to
enforce existing patents and patents we and our licensors or collaborators may obtain in the future.

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our and our licensors' or collaborators' patent applications
and  the  enforcement  or  defense  of  our  or  our  licensors'  or  collaborators'  issued  patents.  On  September  16,  2011,  the  Leahy-Smith  America  Invents  Act,  or  the
Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to US patent law. These include provisions that affect the
way patent applications are prosecuted and may also affect patent litigation. The USPTO 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,  only
became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the
Leahy-Smith  Act  and  its  implementation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  or  our  licensors'  or  collaborators'  patent
applications  and  the  enforcement  or  defense  of  our  or  our  licensors'  or  collaborators'  issued  patents,  all  of  which  could  have  a  material  adverse  effect  on  our
business and financial condition.

Litigation  regarding  patents,  patent  applications,  and  other  proprietary  rights  may  be  expensive,  time  consuming  and  cause  delays  in  the  development  and
manufacturing of our key products.

Our success will depend in part on our ability to operate without infringing the proprietary rights of third parties. The pharmaceutical industry is characterized by
extensive patent litigation. Other parties may have, or obtain in the future, patents and allege that the use of our technologies infringes these patent claims or that
we are employing their proprietary technology without authorization.

In addition, third parties may challenge or infringe upon our existing or future patents. Proceedings involving our patents or patent applications or those of others
could result in adverse decisions regarding:

the patentability of our inventions relating to our key products; and/or
the enforceability, validity, or scope of protection offered by our patents relating to our key products.

If we are unable to avoid infringing the patent rights of others, we may be required to seek a license, defend an infringement action, or challenge the validity of the
patents  in  court.  Regardless  of  the  outcome,  patent  litigation  is  costly  and  time  consuming.  In  some  cases,  we may  not  have  sufficient  resources  to  bring  these
actions to a successful conclusion. In addition, if we do not obtain a license, develop or obtain non-infringing technology, fail to defend an infringement action
successfully or have infringed patents declared invalid, we may:

29

incur substantial monetary damages;
encounter significant delays in bringing our key products to market; and/or
be precluded from participating in the manufacture, use or sale of our key products or methods of treatment requiring licenses.

Even if we are successful in these proceedings, we may incur substantial costs and divert management time and attention in pursuing these proceedings, which
could have a material adverse effect on us.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them.

Because we rely on third parties to develop our products, we must share trade secrets with them. We seek to protect our proprietary technology in part by entering
into  confidentiality  agreements  and,  if  applicable,  material  transfer  agreements,  collaborative  research  agreements,  consulting  agreements  or  other  similar
agreements  with  our  collaborators,  advisors,  employees  and  consultants  prior  to  beginning  research  or  disclosing  proprietary  information.  These  agreements
typically restrict  the ability of our collaborators,  advisors, employees and consultants to publish data potentially relating to our trade secrets. Our academic and
clinical collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure
our intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively by us, although in some cases we may
share these rights with other parties. We may also conduct joint research and development programs which may require us to share trade secrets under the terms of
research  and  development  collaboration  or  similar  agreements.  Despite  our  efforts  to  protect  our  trade  secrets,  our  competitors  may  discover  our  trade  secrets,
either  through  breach  of  these  agreements,  independent  development  or  publication  of  information  including  our  trade  secrets  in  cases  where  we  do  not  have
proprietary or otherwise protected rights at the time of publication. A competitor's discovery of our trade secrets may impair our competitive position and could
have a material adverse effect on our business and financial condition.

Risks Related to Our Common Shares

Our common share price has been volatile in recent years, and may continue to be volatile.

The  market  prices  for  securities  of  biopharmaceutical  companies,  including  ours,  have  historically  been  volatile.  In  the  year  ended  December  31,  2019,  our
common shares traded on the Nasdaq at a high of $2.13 and a low of $0.24 per share and on the TSX at a high of CDN $2.76 and a low of CDN $0.30 per share. In
the year ended December 31, 2018, our common shares traded on the Nasdaq at a high of $9.16 and a low of $1.46 per share and on the TSX at a high of CDN
$11.44 and a low of CDN $1.99 per share. A number of factors could influence the volatility in the trading price of our common shares, including changes in the
economy or in the financial markets, industry related developments, the results of product development and commercialization, changes in government regulations,
and  developments  concerning  proprietary  rights,  litigation  and  cash  flow.  Our  quarterly  losses  may  vary  because  of  the  timing  of  costs  for  manufacturing,
preclinical studies and clinical trials. Also, the reporting of adverse safety events involving our products and public rumors about such events could cause our share
price to decline or experience periods of volatility. Each of these factors could lead to increased volatility in the market price of our common shares. In addition,
changes in the market prices of the securities of our competitors may also lead to fluctuations in the trading price of our common shares.

We have never paid dividends and do not expect to do so in the foreseeable future.

We have not declared or paid any cash dividends on our common or preferred shares to date. The payment of dividends in the future will be dependent on our
earnings and financial condition in addition to such other factors as our board of directors considers appropriate. Unless and until we pay dividends, shareholders
may not receive a return on their shares. There is no present intention by our board of directors to pay dividends on our shares.

Future sales or issuances of equity securities and the conversion of outstanding securities to common shares could decrease the value of the common shares,
dilute  investors'  voting  power,  and  reduce  our  earnings  per  share.  There  are  a  large  number  of  common  shares  underlying  our  outstanding  options  and
warrants and the exercise of these options and/or warrants may depress the market price of our common shares and cause immediate and substantial dilution
to our existing stockholders.

30

As of December 31, 2019, we had 28,938,831 common shares issued and outstanding, preferred shares convertible into an additional 9,440,788 common shares,
outstanding options to purchase 5,366,645 common shares and outstanding warrants to purchase 18,750,000 common shares. The issuance of common shares upon
exercise of our outstanding options and warrants, or the conversion of our preferred shares, will cause immediate and substantial dilution to our stockholders.

We  may  sell  additional  equity  securities  in  future  offerings,  including  through  the  sale  of  securities  convertible  into  equity  securities,  to  finance  operations,
acquisitions or projects, and issue additional common shares if outstanding warrants or stock options are exercised, or preferred shares are converted to common
shares,  which  may  result  in  dilution.  See  the  information  in  the  section  of  this  MD&A  entitled  "Description  of  Share  Capital"  for  details  of  our  outstanding
securities convertible into common shares. In the February 2019 public offering, we issued warrants with a price protection feature that resets the exercise price of
the warrant under certain conditions including the issuance of common shares, or securities convertible into common shares, at prices below the exercise price of
$0.96.

Our board of directors has the authority to authorize certain offers and sales of additional securities without the vote of, or prior notice to, shareholders. Based on
the need for additional capital to fund expected expenditures and growth, it is likely that we will issue additional securities to provide such capital. Such additional
issuances may involve the issuance of a significant number of common shares at prices less than the current market price for our common shares.

Sales of substantial amounts of our securities, or the availability of such securities for sale, as well as the issuance of substantial amounts of our common shares
upon conversion of outstanding convertible equity securities, could adversely affect the prevailing market prices for our securities and dilute investors' earnings per
share. A decline in the market prices of our securities could impair our ability to raise additional capital through the sale of securities should we desire to do so.

US  holders  of  10%  or  more  of  the  voting  power  of  our  common  shares  may  be  subject  to  US  federal  income  taxation  at  ordinary  income  tax  rates  on
undistributed earnings and profits.

There is a risk that we will be classified as a controlled foreign corporation, or CFC, for US federal income tax purposes. We will generally be classified as a CFC
if  more  than  50%  of  our  outstanding  shares,  measured  by  reference  to  voting  power  or  value,  are  owned  (directly,  indirectly  or  by  attribution)  by  "US
Shareholders."  For this  purpose,  a  "US Shareholder"  is  any  US person  that  owns directly,  indirectly  or  by attribution,  10%  or  more  of  the voting  power  of  our
outstanding shares. If we are classified as a CFC, a US Shareholder may be subject to US income taxation at ordinary income tax rates on all or a portion of our
undistributed earnings and profits attributable to "subpart F income" and may also be subject to tax at ordinary income tax rates on any gain realized on a sale of
common shares, to the extent of our current and accumulated earnings and profits attributable to such shares. The CFC rules are complex and US Shareholders of
our common shares are urged to consult their own tax advisors regarding the possible application of the CFC rules to them in their particular circumstances.

We are likely a "passive foreign investment company," which may have adverse US federal income tax consequences for US shareholders.

US investors should be aware that we believe we were classified as a PFIC during the tax years ended 
December 31, 2019 and 2018, and based on current business plans and financial expectations, we believe that we may be a PFIC for the current tax year and may
be a PFIC in future tax years. If we are a PFIC for any year during a US shareholder's holding period of our common shares or Series II First Preferred Shares, then
such US shareholder generally will be required to treat any gain realized upon a disposition of our common shares or Series II First Preferred Shares, or any so-
called "excess distribution" received on our common shares or Series II First Preferred Shares, as ordinary income, and to pay an interest charge on a portion of
such gain or distributions, unless the shareholder makes a timely and effective "qualified electing fund" election, or QEF Election, or a "mark-to-market" election
with respect to our common shares or Series II First Preferred Shares. A US shareholder who makes a QEF Election generally must report on a current basis its
share of our net capital gain and ordinary earnings for any year in which we are a PFIC, which may or may not be readily available, whether or not we distribute
any amounts to our shareholders. A US shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the
fair market value of the common shares over the shareholder's adjusted tax basis therein. A mark-to-market election is not expected to be available with respect to
our Series II First Preferred Shares. Each US shareholder should consult its own tax advisors regarding the PFIC rules and the US federal income tax consequences
of the acquisition, ownership and disposition of our common shares or Series II First Preferred Shares.

31

The effect of comprehensive US tax reform legislation on the Company is uncertain.

On December 22, 2017, the US government enacted H.R. 1, "An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the
budget for fiscal year 2018" (informally titled the "Tax Cuts and Jobs Act"). Among a number of significant changes to the US federal income tax rules, the Tax
Cuts  and  Jobs  Act  reduces  the  marginal  US  corporate  income  tax  rate  from  35%  to  21%,  limits  the  deduction  for  net  interest  expense,  shifts  the  United  States
toward a more territorial tax system, and imposes new taxes to combat erosion of the US federal income tax base, such as a one-time tax on earnings of certain
foreign  subsidiaries  that  were  previously  tax  deferred  and  a  new minimum  tax  on foreign  earnings.  The  effects  of  the  Tax  Cuts and  Jobs Act  on our  company,
whether  adverse  or  favorable,  are  uncertain,  and  may  not  become  evident  for  some  period  of  time,  but  could  have  a  material  adverse  effect  on  our  business,
financial position or results from operations.

It may be difficult for non-Canadian investors to obtain and enforce judgments against us because of our Canadian incorporation and presence.

We  are a corporation  existing  under  the laws of the Province  of British  Columbia,  Canada. Several  of our directors  and officers,  and several  of the experts  are
residents  of  Canada,  and  all  or  a  substantial  portion  of  their  assets,  and  a  substantial  portion  of  our  assets,  are  located  outside  the  United  States.  Consequently,
although we have appointed an agent for service of process in the United States, it may be difficult for holders of our securities who reside in the United States to
effect service within the United States upon those directors and officers, and the experts who are not residents of the United States. It may also be difficult for
holders of our securities who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil
liability and the civil liability of our directors, officers and experts under the United States federal securities laws. Investors should not assume that Canadian courts
(i) would enforce judgments of United States courts obtained in actions against us or such directors, officers or experts predicated upon the civil liability provisions
of the United States federal securities laws or the securities or "blue sky" laws of any state or jurisdiction of the United States or (ii) would enforce, in original
actions, liabilities against us or such directors, officers or experts predicated upon the United States federal securities laws or any securities or "blue sky" laws of
any state or jurisdiction of the United States. In addition, the protections afforded by Canadian securities laws may not be available to investors in the United States.

We are an "emerging growth company," and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make
our common shares less attractive to investors.

We are an "emerging growth company," as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of
exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  emerging  growth  companies,  including  not  being
required  to  comply  with  the  auditor  attestation  requirements  of  Section  404  of  the  Sarbanes-Oxley  Act,  reduced  disclosure  obligations  regarding  executive
compensation  in our periodic  reports  and exemptions  from the requirements  of holding a nonbinding advisory vote on executive  compensation  and shareholder
approval of any golden parachute payments not previously approved. We could be an emerging growth company until the last day of our fiscal year following the
fifth anniversary of the date of the first sale of our common shares pursuant to an effective registration statement under the US Securities Act of 1933, which is
December 31, 2020, although circumstances could cause us to lose that status earlier. We cannot predict if investors will find our common shares less attractive
because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our
common shares and our share price may be more volatile.

We expect to lose our foreign private issuer status which will require us to comply with the US domestic reporting regime under the Exchange Act and result in
significant additional compliance activity and increased costs and expenses.

We are currently a "foreign private issuer," as such term is defined in Rule 405 under the Securities Act, and, therefore, we are not required to comply with all the
periodic  disclosure  and  current  reporting  requirements  of  the  Exchange  Act  and  related  rules  and  regulations.  As  a  result,  there  may  currently  be  less  publicly
available information about us than if we were a United States domestic issuer. For example, currently we are not subject to the proxy rules in the United States and
disclosure with respect to our annual meetings is currently governed by Canadian requirements. Under Rule 405, the determination of foreign private issuer status
is made annually on the last business day of an issuer's most recently completed second fiscal quarter and, accordingly, the next determination will be made with
respect  to  us  on  June  30,  2020.  We  expect  to  lose  our  foreign  private  issuer  status  on  the  next  determination  date  since  (i)  we  believe  at  least  50%  of  our
outstanding common shares were held by US residents and (ii) the majority of our directors are US citizens, which we do not expect to change before the next
determination date.  As a result, we expect to be required to comply with US domestic issuer requirements beginning January 1, 2021.

32

The regulatory and compliance costs to us under US securities laws as a US domestic issuer may be significantly more than costs we incur as a foreign private
issuer. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on US domestic issuer forms with the SEC,
which  are  more  detailed  and  extensive  in  certain  respects  than  the  forms  available  to  a  foreign  private  issuer.  We  will  be  required  under  current  SEC  rules  to
prepare our consolidated financial statements in accordance with US generally accepted accounting principles ("US GAAP") and modify certain of our policies to
comply  with  corporate  governance  practices  associated  with  US  domestic  issuers.    In  addition,  we  may  lose  our  ability  to  rely  upon  exemptions  from  certain
corporate governance requirements on US stock exchanges that are available to foreign private issuers, and exemptions from requirements related to the preparation
and solicitation of proxies (including compliance with full disclosure obligations regarding executive compensation in proxy statements and the requirements of
holding a nonbinding advisory vote on certain  executive  compensation  matters,  such as "say on pay" and "say on frequency").  Moreover, we will no longer be
exempt from certain of the provisions of US securities laws, such as Regulation FD (which restricts the selective disclosure of material information), exemptions
for filing beneficial ownership reports under Section 16(a) for officers, directors and 10% shareholders and the Section 16(b) short swing profit rules. In light of our
expectations, we have already started to prepare for the consequences of becoming a US domestic issuer, including those described above, and we expect that the
loss of foreign private issuer status will increase our legal and financial compliance costs and will make some activities highly time-consuming and costly. The
additional costs could have an adverse impact on our results of operations, financial position and cash flows.

In addition, the transition to being treated as a US domestic issuer may make it more difficult and expensive for us to obtain director and officer liability insurance,
and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage.

Any failure to maintain an effective system of internal controls may result in material misstatements of our consolidated financial statements or cause us to fail
to meet our reporting obligations or fail to prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would
harm our business and could negatively impact the price of our common shares.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. If we fail to maintain an effective system of internal controls,
we might not be able to report our financial results accurately or prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting,
which  would  harm  our  business  and  could  negatively  impact  the  price  of  our  common  shares.  While  we  believe  that  we  have  sufficient  personnel  and  review
procedures to allow us to maintain an effective system of internal controls, we cannot provide assurance that we will not experience potential material weaknesses
in our internal control. Even if we conclude that our internal control over financial reporting provides reasonable assurance regarding the reliability of financial
reporting and the preparation of consolidated financial statements for external purposes in accordance with IFRS as issued by the IASB, because of its inherent
limitations, internal control over financial reporting may not prevent or detect fraud or misstatements. Failure to implement required new or improved controls, or
difficulties encountered in their implementation, could harm our results of operations or cause us to fail to meet our future reporting obligations.

If we fail to timely achieve and maintain the adequacy of our internal control over financial reporting, we may not be able to produce reliable financial reports or
help  prevent  fraud.  Our  failure  to  achieve  and  maintain  effective  internal  control  over  financial  reporting  could  prevent  us  from  complying  with  our  reporting
obligations on a timely basis, which could result in the loss of investor confidence in the reliability of our consolidated financial statements, harm our business and
negatively impact the trading price of our common shares.

33

Our charter documents and certain Canadian legislation could delay or deter a change of control, limit attempts by our shareholders to replace or remove our
current management and limit the market price of our common shares.

Our authorized preferred shares are available for issuance from time to time at the discretion of our board of directors, without shareholder approval. Our articles
grant our board of directors the authority to determine the special rights and restrictions granted to or imposed on any unissued series of preferred shares, and those
rights may be superior to those of our common shares. Further, the Investment Canada Act subjects any acquisition of control of a company by a non-Canadian to
government  review  if  the  value  of  the  assets  as  calculated  pursuant  to  the  legislation  exceeds  a  threshold  amount  or  in  other  circumstances  determined  at  the
discretion of the Canadian government. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to be of net
benefit  to  Canada  and  the  Canadian  government  is  satisfied  that  no  other  important  concerns  arise  from  the  acquisition  of  control.  Any  of  the  foregoing  could
prevent or delay a change of control and may deprive or limit strategic opportunities to our shareholders to sell their shares.

DIVIDENDS

There are no restrictions in the Company's articles preventing the Company from paying dividends. The Company has not declared or paid any dividends since
incorporation.  The  directors  of  the  Company  anticipate  that  the  Company  will  retain  all  future  earnings  and  other  cash  resources  for  the  future  operation  and
development of its business, and accordingly, do not intend to declare or pay any cash dividends in the foreseeable future. Payment of any future dividends will be
at  the discretion  of  the  board  of  directors  after  taking  into  account  many  factors  including  the  Company's  operating  results,  financial  condition  and current  and
anticipated cash assets.

Overview

DESCRIPTION OF SHARE CAPITAL

Our authorized share capital consists of an unlimited number of common shares, Class B shares and First Preferred shares, in each case without nominal or par
value.

The holders of common shares are entitled to receive notice of and to attend all annual and special meetings of our shareholders and to one vote per share held at
each such meeting, and they are entitled to receive dividends as determined and declared by our Board of Directors.

Subject  to  the  rights  of  the  holders  of  any  other  class  of  our  shares  entitled  to  receive  dividends  in  priority  to  or  concurrently  with  the  holders  of  the  common
shares, our Board of Directors may in its sole discretion declare dividends on the common shares to the exclusion of any other class of shares of the Company.

In the event of our liquidation, dissolution or winding up or other distribution of our assets among our shareholders for the purpose of winding up our affairs, the
holders of the common shares shall, subject to the rights of the holders of any other class of shares entitled to receive our assets upon such a distribution in priority
to or concurrently with the holders of the common shares, be entitled to participate in the distribution. Such distribution shall be made in equal amounts per share
on all the common shares at the time outstanding without preference or distinction.

The holders of the Class B shares are entitled to receive notice of and to attend any meeting of our shareholders but shall not be entitled to vote any of their Class B
shares at any such meeting. Each issued and fully paid Class B share may at any time be converted, at the option of the holder, into one common share.

34

The First Preferred shares may at any time and from time to time be issued in one or more series and our the Board of Directors may before the issue thereof fix the
number of shares in, and determine the designation, rights, privileges, restrictions and conditions attaching to the shares of, each series of First Preferred shares.

The First Preferred shares shall be entitled to priority over the common shares and Class B shares and all other shares ranking junior to the First Preferred shares
with respect to the payment of dividends and the distribution of our assets in the event of our liquidation, dissolution or winding up or other distribution of our
assets among our shareholders for the purpose of winding up our affairs.

The First Preferred shares of each series rank on a parity with the First Preferred shares of every other series with respect to priority in the payment of dividends
and in the distribution of our assets in the event of our liquidation, dissolution or winding up or other distribution of our assets among our shareholders for the
purpose of winding up our affairs.

Share capital issued - year ended December 31, 2019

In February 2019, we completed an underwritten public offering of 6,550,000 common share units and 12,200,000 Series II Non-Voting Convertible First Preferred
Share units, each issued at $0.80 per unit. The gross proceeds from this offering were $15,000, before deducting offering expenses of $1,117. Each common share
unit is comprised of one common share of the Company and one common share purchase warrant. Each common share purchase warrant will be exercisable for one
common share at a price of $0.96 per common share purchase warrant for sixty months. Each preferred share unit is comprised of one Series II First Preferred
Share of the Company and one Series II First Preferred Share purchase warrant. Each Series II First Preferred Share purchase warrant will be exercisable for one
Series II First Preferred Share at a price of $0.96 per Series II First Preferred Share purchase warrant for sixty months. Each purchase warrant has a price protection
feature that resets the exercise price of the warrant under certain conditions including the issuance of common shares, or securities convertible into common shares,
at prices below the exercise price.

In addition, in the event of a "Fundamental Transaction" (as defined in the related warrant agreement, which generally includes any merger with another entity, the
sale, transfer or other disposition of all or substantially all of our assets to another entity, or the acquisition by a person of more than 50% of our common stock),
each warrant holder will have the right up to 90 days after the consummation of the Fundamental Transaction to require us to repurchase the warrant for a purchase
price in cash equal to the Black Scholes value (as calculated under the warrant agreement) of the then remaining unexercised portion of such warrant on the date of
such Fundamental Transaction.

During the year ended December 31, 2019, 7,700,000 Series II First Preferred Shares were converted into 7,700,000 common shares.

Share capital issued - for the year ended December 31, 2018

In a June 2018 amendment to the license agreement for SIRPαFc, the sublicense revenue sharing provisions were removed in return for a payment to the licensors
of $2,290 in the form of 369,621 common shares, which was recorded in research and development expenses.

During the year ended December 31, 2018, 35,154,286 Series I First Preferred Shares were converted into 1,171,806 common shares.

Share capital issued - for the year ended December 31, 2017

In June 2017, the Company completed an underwritten public offering of common shares and Series II Preferred Shares in the United States. In the offering, the
Company sold 2,949,674 common shares and 3,250,000 Series II Preferred Shares at a price of $5.00 per share. The gross proceeds from this offering were $30,998
before deducting offering expenses of $2,116. 

Concurrently with the closing of the offering, the Company amended the terms of certain common share purchase warrants, or the Preferred Warrants, held by an
existing  institutional  investor.  The  Preferred  Warrants  were  previously  exercisable  to  acquire  up  to  1,190,476  common  shares  at  an  exercise  price  of  $7.93  per
common  share  until  December  13,  2018  (in  each  case  after  giving  effect  to  the  30:1  consolidation  previously  effected  by  the  Company).  Pursuant  to  the
amendment, each Preferred Warrants will now be exercisable, at the discretion of the holder, to acquire either one common share or one Series II Preferred Share.
All  other  terms  of  the  Preferred  Warrants  (including  the  aggregate  number  of  shares  issuable  on  exercise  of  the  Preferred  Warrants,  the  exercise  price  and  the
expiry date) remain unchanged.

35

In December 2017, the Company completed a non-brokered private placement financing and sold 1,950,000 common shares and 400,000 Series II Preferred Shares
at a price of $8.50 per share yielding gross proceeds of $19,975 before deducting offering expenses of $1,405.

During the year ended December 31, 2017, 13,332 common shares were issued on the exercise of 399,980 common share purchase warrants for proceeds of $156;

Audit Committee Oversight

Since  the  commencement  of  our  most  recently  completed  fiscal  year  and  adoption  of  the  audit  committee  charter,  the  Board  has  not  failed  to  adopt  a
recommendation of the audit committee to nominate or compensate an external auditor.

Pre-Approval Policies and Procedures

The  audit  committee  has  adopted  specific  policies  and  procedures  for  the  engagement  of  audit  and  non-audit  services  as  set  out  in  our  Auditor  Services  Pre-
Approval Policy. Pursuant  to the Policy,  the audit  committee  on an annual  basis may approve  the provision  of a specified  list  of audit  and permitted  non-audit
services that the audit committee believes to be typical, reoccurring or otherwise likely to be provided by the external auditor during the then current fiscal year. All
pre-approvals granted under this Policy shall be sufficiently detailed as to the particular services being provided that it will not be necessary for management of
Trillium to exercise any discretion in determining whether a particular service has been pre-approved.

In addition, pursuant to the Policy the audit committee has delegated its pre-approval authority to the Chair of the audit committee for services where the aggregate
fees are estimated to be less than or equal to Cdn. $50,000.  The Chair of the audit committee is required to report any such granted pre-approvals to the audit
committee at its next scheduled meeting.  The audit committee shall not delegate to management the audit committee's responsibilities for pre-approving audit and
non-audit services to be performed by the external auditor.

Pursuant to the Policy, there is an exception to the pre-approval requirements for permitted non-audit services, provided all such services were not recognized at the
time  of  the  engagement  to  be  non-audit  services  and,  once  recognized,  are  promptly  brought  to  the  attention  of  the  audit  committee  and  approved  prior  to  the
completion  of  the  audit.    The  aggregate  amount  of  all  services  approved  in  this  manner  may  not  constitute  more  than  five  percent  of  the  total  fees  paid  to  the
external auditor during the fiscal year in which the services are provided.

CHARTER OF THE AUDIT COMMITTEE 
OF THE BOARD OF DIRECTORS

POWER, AUTHORITY AND PURPOSE OF THE COMMITTEE

The purpose of the Audit Committee (the "Committee") of the Board of Directors (the "Board") of Trillium Therapeutics Inc. (together with its subsidiaries, the
"Company") is to assist the Board in:

Overseeing the integrity of the Company's financial statements and the Company's accounting and financial reporting processes and financial statement

Overseeing the qualifications and independence of the Company's registered public accounting firm (independent auditor).

Overseeing the performance of the Company's independent auditor.

Overseeing the design, implementation and on-going effectiveness of the Company's systems of disclosure controls and procedures, risk management

While the Committee has the responsibilities and powers set forth in this charter (this "Charter"), it is not the duty of the Committee to plan or conduct audits or to

responsible for preparing the Company's financial statements, and the Company's independent auditor is responsible for auditing those financial statements.

The  Committee  has  the  authority  to  undertake  the  specific  duties  and  responsibilities  listed  below  and  such  other  duties  as  the  Board  may  from  time  to  time
prescribe. It is acknowledged, however, that all of the areas of oversight listed below may not be relevant to all of the matters and tasks that the Committee may
consider and act upon from time to time, and the members of the Committee in their judgment may determine the relevance thereof and the attention such items
will receive in any particular context.

The Committee shall have the power and authority to act independently of management, conduct investigations into any matters within its scope of responsibility,
hire  and  obtain  advice  from  its  own outside  legal,  accounting  or  other  advisors  who will  report  solely  to  the  Committee,  set  and  pay the  compensation  for  any
advisors employed by the Committee and communicate directly with internal and external auditors.

Committee members and the Committee Chair shall receive such remuneration for their service on the Committee as the Board may determine from time to time,
on the recommendation of the Compensation Committee.

been recognized in other comprehensive loss.

Overview

BUSINESS

We  are  a  clinical  stage  immuno-oncology  company  developing  innovative  therapies  for  the  treatment  of  cancer.  Our  most  advanced  program,  TTI-621,  is  a
SIRPαFc fusion protein that consists of the extracellular CD47-binding domain of human signal regulatory protein alpha, or SIRPα, linked to the Fc region of a
human  immunoglobulin  G1,  or  IgG1.  It  is  designed  to  act  as  a  soluble  decoy  receptor,  preventing  CD47  from  delivering  its  inhibitory  ("do  not  eat")  signal.
Neutralization of the inhibitory CD47 signal enables the activation of macrophage anti-tumor effects by pro-phagocytic ("eat") signals. The IgG1 Fc region of TTI-
621 may also assist in the activation of macrophages by engaging Fc receptors. TTI-621 has shown single agent activity by both local and/or systemic delivery in
multiple B- and T-cell lymphoma indications and has been well tolerated in over 200 patients to date.

We are also developing a second SIRPαFc fusion protein, TTI-622, which is in a phase 1 clinical trial. TTI-622 consists of the extracellular CD47-binding domain
of human SIRPα linked to a human immunoglobulin G4, or IgG4 Fc region, which has a decreased ability to engage Fc receptors than an IgG1 Fc. Both SIRPαFc
fusion proteins enable CD47 blockade with different levels of Fc receptor engagement on macrophages and thus may find unique applications.

We also have an internally-developed small molecule stimulator of interferon genes, or STING, agonist program available for out-license.

Our Strategy

Our goal is to become a leading innovator in the field of oncology by targeting immune-regulatory pathways that tumor cells exploit to evade the host immune
system. We believe we have a differentiated and comprehensive approach to targeting CD47, with the development of two SIRPαFc fusion proteins, TTI-621 and
TTI-622. We intend to:

Rapidly advance the clinical development of TTI-621 and TTI-622. We are currently in the process of identifying the maximum tolerated or
recommended phase 2 doses for both TTI-621 and TTI-622, and plan to rapidly advance both molecules into phase 1b/2 studies.

Focus our TTI-621 and TTI-622 clinical programs on promising cancer indications. Because CD47 is highly expressed by multiple liquid and solid
tumors, and high expression is correlated with worse clinical outcomes, we believe our SIRPαFc fusion proteins have the potential to be effective in a
variety of cancers. We have already identified several cancers where we saw positive responses to TTI-621 in patients, including B- and T-cell
lymphomas.

Focus our TTI-621 and TTI-622 clinical programs on promising combinations. While we believe that a monotherapy path for TTI-621 in certain
indications shows promise, we are also planning to evaluate TTI-621 and TTI-622 in combination with other anti-cancer drugs, including
immunomodulatory agents.

Our Pipeline 

SIRPαFc

Blocking the CD47 "do not eat" signal using a SIRPαFc decoy receptor

The immune system is the body's mechanism  to identify  and eliminate  pathogens, and can be divided into the innate immune  system and the adaptive  immune
system. The innate immune system is the body's first line of defense to identify and eliminate pathogens and consists of proteins and cells, such as macrophages,
that  identify  and  provide  an  immediate  response  to  pathogens.  The  adaptive  immune  system  is  activated  by,  and  adapts  to,  pathogens,  creating  a  targeted  and
durable response. Cancer cells often have the ability to reduce the immune system's ability to recognize and destroy them.

Macrophages  are  a  type  of  white  blood  cell  that  can  ingest  and  destroy  (phagocytose)  other  cells.  Macrophage  activity  is  controlled  by  both  positive  "eat"  and
negative "do not eat" signals. Recently, a role for macrophages in the control of tumors has been described. Tumor cells may express "eat" signals (e.g. calreticulin)
that make themselves visible to macrophages. To counterbalance this increased visibility the tumor cells often express high levels of CD47, which transmits a "do
not eat" signal by binding SIRPα on the surface of macrophages. Elevated expression of CD47 has been observed across a range of hematological and solid tumors.
In many cases, high CD47 expression was shown to have negative clinical consequences, correlating with more aggressive disease and poor survival.

Our most advanced program, TTI-621, is a novel SIRPαFc fusion protein that harnesses the innate immune system by blocking the activity of CD47. TTI-621 is a
protein that consists of the CD47-binding domain of human SIRPα linked to the Fc region of IgG1. It is designed to act as a soluble decoy receptor, preventing
CD47  from  delivering  its  inhibitory  signal.  Neutralization  of  the  inhibitory  CD47  signal  enables  the  activation  of  macrophage  anti-tumor  effects  by  the  pro-
phagocytic "eat" signals. The IgG1 Fc region of TTI-621 may also assist in the activation of macrophages by engaging Fc receptors. Our second SIRPαFc fusion
protein TTI-622 consists of the same CD47-binding domain of human SIRPα and is linked to the Fc region of IgG4. The IgG4 Fc region of TTI-622 is expected to
have  a  decreased  ability  to  engage  activating  Fc  receptors  compared  to  an  IgG1 Fc, and  thus  provide  a  more  modest  "eat"  signal  to  macrophages,  allowing  for
greater tolerability and higher CD47 blockade but lower potency. TTI-622 will allow us to assess how higher CD47 blockade with an IgG4-based agent in patients
compares to lower CD47 blockade with an IgG1-based drug (TTI-621).

In preclinical studies, TTI-621 and TTI-622 frequently triggered significant macrophage-mediated tumor cell phagocytosis in vitro compared to control treatment.
In vivo, both fusion proteins exhibited anti-tumor activity in human xenograft models.

Management’s Discussion and Analysis

In addition to their direct anti-tumor activity, macrophages can also function as antigen-presenting cells and stimulate antigen-specific T-cells. Thus, it is possible
that increasing tumor cell phagocytosis after SIRPαFc exposure may result in enhanced adaptive immunity. In support of this, CD47 antibody blockade has been
recently  shown  to  augment  antigen  presentation  and  prime  an  anti-tumor  cytotoxic  T-cell  response  in  immune-competent  mice.  In  2016,  we  presented  data
demonstrating  that  TTI-621  can  augment  antigen-specific  T-cell  responses  in  vitro.  CD47  blockade  has  also  been  reported  to  promote  tumor-specific  T-cell
responses through a dendritic cell-based mechanism, although the effect of SIRPαFc on dendritic cells is currently unknown.

The  figure  below  illustrates  how  SIRPαFc  blocks  the  CD47  "do  not  eat"  signal  and  engages  activating  Fc  receptors  on  macrophages,  leading  to  tumor  cell
phagocytosis, increased antigen presentation and enhanced T-cell responses.

By inhibiting the CD47 "do not eat" signal, we believe SIRPαFc has the ability to promote the macrophage-mediated killing of tumor cells in a broad variety of
cancers both as a monotherapy and in combination with other immune therapies. Both SIRPαFc fusion proteins enable CD47 blockade with different levels of Fc
receptor engagement on macrophages and thus may find unique applications.

Management’s Discussion and Analysis

Combination Therapy

We believe that SIRPαFc enhancement of macrophage activity, and possibly T-cell responses, could be synergistic with other immune-mediated therapies. Since
many cancer antibodies work at least in part by activating cells of the innate immune system, it may be possible to enhance the potency of these agents by blocking
the  negative  "do  not  eat"  CD47  signal  that  tumor  cells  deliver  to  macrophages.  In  fact,  we  have  observed  anti-tumor  activity  when  combining  SIRPαFc  with
rituximab  in  both  preclinical  studies  and  in  B-cell  lymphoma  patients.  We  hypothesize  that  SIRPαFc  may  act  synergistically  with  other  immunological  agents,
including T-cell checkpoint inhibitors (e.g. pembrolizumab and nivolumab), cancer vaccines, oncolytic viruses or chimeric antigen receptor, or CAR T-cells.

SIRPαFc Clinical Development - TTI-621

A phase 1 multicenter, open-label study in which patients with advanced relapsed or refractory hematologic malignancies receive intravenous TTI-621 is currently
in  progress  (NCT02663518).  The  study  consists  of  four  parts:  (a)  completed  "Parts  1-3"  in  hematologic  malignancies,  with  dosing  up  to  0.5  mg/kg,  conducted
under  initial  dose-limiting  toxicity,  or  DLT,  criteria;  and  (b)  ongoing  "Part  4"  in  cutaneous  T-cell  lymphoma  (CTCL),  utilizing  revised  DLT  criteria  for
thrombocytopenia (as detailed below) and an amended protocol to allow for dosing above 0.5 mg/kg.

On January 7, 2020, we released an update on Parts 1-3 of the TTI-621 intravenous study. Over 200 patients received doses ranging from 0.05 to 0.5 mg/kg, with
the majority enrolled at 0.2-0.5 mg/kg dose levels. Updated safety data demonstrate that TTI-621 is generally well tolerated. The most frequent drug related adverse
events were low-grade infusion reactions and transient thrombocytopenia that was not associated with bleeding. Monotherapy activity has been observed in patients
across a range of hematologic malignancies, including cutaneous T-cell lymphoma, or CTCL (19% objective response rate), peripheral T-cell lymphoma, or PTCL
(18% objective response rate), and diffuse large B-cell lymphoma (29% objective response rate). Notably, most patients were at an advanced stage of their disease
and heavily pretreated, with median number of prior systemic treatments between 3 and 5 (range 1-26).

Part  4  of  the  study  is  now  ongoing  under  an  amended  protocol.  Given  the  transient  nature  of  thrombocytopenia  observed  in  Parts  1-3  of  the  study,  the  DLT
definition for thrombocytopenia was revised, from Grade 4 of any duration in Parts 1-3, to Grade 4 lasting 72+ hours or a platelet count less than 10,000/microliter
at  any  time  in  Part  4.  No  DLTs  have  been  observed  at  the  0.5  and  0.7  mg/kg  dose  levels;  furthermore  no  Grade  4  thrombocytopenia  of  any  duration  has  been
observed. The study is now dosing at the 1.4 mg/kg level, and the protocol allows for higher dosing if appropriate.

We  have  also  conducted  an  open-label  phase  1  trial  in  which  TTI-621  was  delivered  by  intratumoral  injection  in  patients  with  relapsed  and  refractory,
percutaneously-accessible cancers. As reported at the American Society of Hematology 60th Annual Meeting in December 2018, local delivery of TTI-621 was
well tolerated, and reductions in Composite Assessment of Index Lesion Severity, or CAILS, scores, which measure local lesion responses, were observed in 91%
of evaluable mycosis fungoides patients, with 41% exhibiting reductions of 50% or greater. These responses occurred rapidly within the 2-week induction period.
Collectively,  these  data  provide  clinical  proof-of-concept  for  TTI-621.  As  announced  in  October  2019,  the  intratumoral  study  has  been  closed  and  we  are  now
focused on intravenous delivery of TTI-621.

TTI-621 was granted an Orphan Drug Designation by the FDA for the treatment of CTCL. Orphan Drug Designation qualifies the sponsor of the drug candidate for
various development incentives, which may include tax credits for qualified clinical testing, an exemption from fees under the Prescription Drug User Fee Act, and
a seven-year marketing exclusivity period following approval.

SIRPαFc Clinical Development - TTI-622

A two-part, multicenter, open-label, phase 1a/1b study of TTI-622 in patients with advanced relapsed or refractory lymphoma or multiple myeloma is currently in
progress  (NCT03530683).  In  the  phase  1a  dose-escalation  part,  patients  are  being  enrolled  in  sequential  dose  cohorts  to  receive  TTI-622  once  weekly  to
characterize safety, tolerability, pharmacokinetics, and to determine the maximum tolerated dose. In the phase 1b part, patients with hematologic malignancies will
be treated with TTI-622 in combination with other agents.

TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

On January 7, 2020, we reported that we have completed dosing in the fourth dose escalation cohort, where patients received a top dose of 2.0 mg/kg. No DLTs or
drug-related  serious  adverse  events  have  been  observed,  and  enrollment  is  now  open  in  the  sixth  cohort,  with  a  dose  of  8.0  mg/kg.  Although  TTI-622  is  being
developed primarily as a combination therapy, a partial response has been observed in a DLBCL patient receiving 0.8 mg/kg TTI-622 monotherapy.

SIRPαFc Key Takeaways

Multiple clinical approaches. We have a diversified approach to CD47 blockade, with two decoy receptors (TTI-621 and TTI-622) with different
pharmacological properties in clinical development.

Tolerability and safety. TTI-621 has been well tolerated in over 200 patients to date.

Demonstrated clear signals of activity. TTI-621 monotherapy has produced positive signals of clinical activity in CTCL, PTCL and DLBCL patients. A
signal of activity was also seen in DLBCL patients when combined with rituximab.

SIRPαFc Competition

There are a number of companies developing blocking agents to the CD47-SIRPα axis, which can be broadly classified into six groups which include, but are not
limited to:

CD47-specific antibodies: Forty Seven Inc. (phase 2); Celgene Corporation (phase 1), Innovent Biologics (Suzhou) Co. (phase 1), Arch Oncology (phase
1), I -Mab Biopharma (phase 1), Jiangsu Hengrui Medicine Co. (phase 1), Seattle Genetics (phase 1); Phanes Therapeutics (preclinical), ImmuneOncia
(preclinical), Eucure Biopharma (preclinical), Elpiscience (preclinical).
CD47 bispecific antibodies: TG Therapeutics/Light Chain Bioscience (phase 1), Abpro Therapeutics (preclinical), Hummingbird BioSciences
(preclinical), ImmuneOncia (preclinical), Innovent Biologics (Suzhou) Co. (preclinical), Pharmabcine (preclinical), Phanes Therapeutics (preclinical)
Mutated high affinity SIRPαFc: ALX Oncology (phase 1).
SIRPα-specific antibodies: Celgene, OSE Immunotherapeutics/Boehringer Ingelheim (phase 1); Arch Oncology (preclinical), Forty Seven Inc
(preclinical), Compass Therapeutics (preclinical), Elpiscience (preclinical).
SIRPαFc-agonist fusion protein: Shattuck Labs (preclinical).
Small molecule inhibitor: Aurigene Discovery Technologies (preclinical), Paradigm Shift Therapeutics (preclinical), Vivoryon AG (preclinical).

We believe that the IgG1 Fc region differentiates TTI-621 from most other CD47 blocking agents. The IgG1 Fc maximizes potency by delivering an activating
signal to macrophages through Fc receptors. With this higher potency, we believe that TTI-621 has a higher likelihood of monotherapy activity and therefore is not
dependent upon a combination with another IgG1 antibody. Indeed, to our knowledge TTI-621 is the only CD47 blocking agent which has exhibited meaningful
monotherapy activity and resulted in complete responses in cancer patients as a monotherapy.

Furthermore, we believe that both TTI-621 and TTI-622 are differentiated from other CD47 blocking agents by minimal binding to human red blood cells. This
property  confers  several  possible  advantages,  including  avoidance  of  drug-induced  anemia,  avoidance  of  the  "antigen  sink  effect"  (i.e.  removal  of  drug  from
circulation by RBCs) and non-interference with laboratory blood typing tests.

Management’s Discussion and Analysis

STING Agonist

Our pipeline also includes a preclinical STING (stimulator of interferon genes) agonist program. STING is an adaptor protein involved in sensing cytosolic DNA
that plays a key role in promoting tumor immunity. As previously announced, the program is earmarked for out-licensing.

Plan of Operations

Our main focus in the near term is to 1) identify the maximum tolerated dose or recommended phase 2 dose for TTI-621 under the revised DLT criteria in Part 4 of
study NCT02663518 and 2) identify the maximum tolerated dose or recommended phase 2 dose for TTI-622 in the ongoing study NCT03530683. Subsequently,
we intend to initiate phase 1b/2 combination studies for both agents. For TTI-621, we are also considering a monotherapy expansion cohort in T-cell lymphoma.
We will also undertake research, manufacturing and regulatory activities to support the CD47 clinical programs.

Recent Events

In January 2020, we completed an underwritten public offering for gross proceeds of $116,955 comprised of 41,279,090 common shares and 1,250,000 Series II
Non-Voting Convertible First Preferred Shares, each issued at $2.75 per share.

Corporate Restructuring and Impairment

On October 22, 2019, we announced a corporate restructuring program that reduced our staff by 40%, from 43 to 26 active employees. We also decided to out-
license our preclinical STING agonist program, and we expect further cost savings will be achieved through operational efficiencies. We incurred cash payments of
approximately $841 related to employee separation benefits.

During the year ended December 31, 2019, we recognized an impairment charge of $2,952 to fully write down the remaining carrying value of the intangible assets
recognized  in  the  January  26,  2016  acquisition  of  Fluorinov  Pharma  Inc.,  or  Fluorinov.  The  factors  leading  to  this  impairment  included  the  discontinuation  of
discovery research activities and revised expected realization from Fluorinov legacy products.

Recent Governance Changes

Effective September 25, 2019, Dr. Jan Skvarka was hired as the President and Chief Executive Officer and as a director of Trillium. Prior to joining Trillium, Dr.
Skvarka was President and Chief Executive Officer of Tal Medical, a clinical-stage neuroscience company in Boston, Massachusetts, from 2014 until 2018. Prior to
that he had a long career from 1999 to 2013 as a healthcare consultant at Bain & Company, Boston. He was a partner in the Healthcare practice from 2007 until
2013,  with  a  focus  on  pharmaceutical,  biotechnology  and  medical  technology  companies.  Earlier  in  his  career  he  worked  in  the  corporate  finance  arm  of  Price
Waterhouse in London, UK and Vienna, Austria. Dr. Skvarka holds an MBA degree from Harvard Business School and a PhD in Economics from the University of
Economics, Bratislava, Slovakia.

Effective February 6, 2020, Mr. Paul Walker joined the board and Dr. Ali Behbahani joined as a Board Observer. Both Mr. Walker and Dr. Behbahani are general
partners of New Enterprise Associates, a global venture capital firm.

We also announced that Dr. Robert Uger has stepped down from the Board of Directors effective February 6, 2020 and continues as Trillium's Chief Scientific
Officer.

Fluorinov Amendment

On  January  26,  2016,  Trillium  purchased  all  the  issued  and  outstanding  shares  of  Fluorinov,  a  private  oncology  company,  to  access  its  proprietary  medicinal
chemistry  platform.  On May  13, 2019, Trillium  and the former  Fluorinov  shareholders  amended  the purchase  agreements  to remove  the existing  milestone  and
royalty payments in favour of a revenue sharing arrangement. On the deletion of the milestones from the agreements, the existing contingent consideration was
reduced to $nil.

Legal Proceedings

To  our  knowledge,  there  have  not  been  any  legal  or  arbitration  proceedings,  including  those  relating  to  bankruptcy,  receivership  or  similar  proceedings,  those
involving any third party, and governmental proceedings pending or known to be contemplated, which may have, or have had in the recent past, significant effect
on our financial position or profitability.

Also, to our knowledge, there have been no material proceedings in which any director, any member of senior management, or any of our affiliates is either a party
adverse to us or any of our subsidiaries or has a material interest adverse to us or any of our subsidiaries.

RESULTS OF OPERATIONS

For the years ended December 31, 2019 and 2018

Overview

Since inception, we have incurred losses while advancing the research and development of our products. Net loss for the year ended December 31, 2019 of $41,622
was higher than the loss of $32,866 for the year ended December 31, 2018. The net loss was higher due mainly to a warrant liability revaluation loss of $5,747, the
write down of Fluorinov intangible assets of $2,952, higher manufacturing  costs, and a net foreign currency loss of $846 in the current year compared to a net
foreign currency gain of $2,708 in the prior year. The higher loss was partially offset by lower clinical trial expenses.

Net loss for the three months ended December 31, 2019 of $19,201 was higher than the loss of $6,480 for the three months ended December 31, 2018 due mainly to
a warrant liability revaluation loss of $10,694, DSU revaluation loss of $1,726 as compared to revaluation gain of $907, and a net foreign currency loss of $227 in
the current period compared to a net foreign currency gain of $1,519 for the three months ended December 31, 2018. This was partially offset by lower clinical trial
related expenses for the three months ended December 31, 2019.

Revenue

In  July  2019,  we  entered  into  a  right-to-use  license  agreement  for  one  of  our  small  molecule  compounds  with  initial  license  fees  of  $99. Sales-based  royalties,
anniversary payments, and milestone payments will be recognized when incurred in future periods.

For the year ended December 31, 2019, the Company recognized licensing revenues of $124 (2018 - $nil).

Most of our resources were focused on the development of our SIRPαFc program. For the year ended December 31, 2019, SIRPαFc research and development
costs were lower than the prior year due mainly to lower clinical trial related expenses and the amendment to the SIRPαFc license agreement with the issuance of
$2,290  of  common  shares  to  the  licensors  in  the  prior  year.  This  cost  decrease  was  partially  offset  by  higher  manufacturing  costs  and  higher  share-based
compensation expense in the current year.

Small  molecule  program  expenses  were  higher  than  the  prior  year  as  the  immuno-oncology  discovery  program  was  expanded  to  include  the  STING  agonist

The research and development program expenses for the three months ended December 31, 2019 of $3,345 were lower than the same period last year due mainly to
lower clinical trial related expenses. Salaries, fees and short-term benefits were higher for the three months ended December 31, 2019 compared to the same period
in the prior year due mainly to a provision for retention agreements provided to key employees. Share-based compensation costs were lower compared to the same
period  last  year  due  mainly  to  a  higher  number  of  stock  options  forfeited  and  due  to  the  lower  fair  value  of  stock  option  grants  in  the  current  year  period.
Amortization of intangible assets was $nil as compared to the prior year period as the legacy Fluorinov intangible assets were written off in the third quarter of
2019. Depreciation of property and equipment increased due to the adoption of IFRS 16 Leases in 2019.

The research and development program expenses for the year ended December 31, 2019 of $16,110 were lower than the same period last year due mainly to lower
clinical trial related expenses with the initiation of the dose optimization TTI-621 intravenous trial and the termination of the TTI-621 intratumoral trial, partially
offset by higher manufacturing costs. Salaries, fees, and short-term benefits were higher in the year ended December 31, 2019 due mainly to severance costs and a
provision for retention agreements provided to key employees. Share-based compensation costs decreased due mainly to a higher number of stock options forfeited
and due to the lower fair value of stock option grants in the current year period. Amortization of intangible assets was lower as compared to the prior year period as
the  legacy  Fluorinov  intangible  assets  were  written  off  in  the  third  quarter  of  2019.  The  reduction  in  the  fair  value  of  contingent  consideration  related  to  the
Fluorinov purchase to $nil resulted from an amendment to the Fluorinov purchase agreements to remove future contingent milestones and royalties in favour of a
net revenue sharing formula. Depreciation of property and equipment increased due to the adoption of IFRS 16 Leases in 2019.

General and administrative expenses for the three months ended December 31, 2019 of $352 were comparable to the prior year period of $379. The change in fair
value of DSUs was an expense in 2019 due to an increase in the DSU value resulting from an increased common share price in 2019 as compared to a recovery in
the prior year caused by a decreased share price. The share-based compensation expense was comparable to the same period in the prior year.

General and administrative expenses for the years ended December 31, 2019 of $1,591 were comparable to the prior year of $1,621. Salaries, fees and short-term
benefits increased due mainly to the hiring of our CEO, and a provision for retention agreements provided to key employees. The change in fair value of DSUs was
an expense in 2019 due to an increase in the DSU value resulting from an increased common share price in 2019 as compared to a recovery in the prior year caused
by a decreased share price. The share-based compensation expense was comparable to the prior year.

Finance income and costs, foreign exchange gains and losses, and revaluation of warrant liability

Finance income for the three months and year ended December 31, 2019 of $113 and $614, respectively, were lower than the prior year comparable periods due to
lower average cash balances.

Finance  costs  for  the  three  months  and  year  ended  December  31,  2019  of  $43  and  $177,  respectively,  were  higher  than  the  prior  year  periods  due  to  the
implementation of IFRS 16 Leases which resulted in accreted interest expense relating to the lease liability.

During the three months ended December 31, 2019, we recorded a net foreign currency loss of $227, compared to a net foreign currency gain of $1,519 for the
comparative period in 2018. The net foreign currency loss in the current period reflected a weakening of the US dollar versus the Canadian dollar while holding net
US dollar denominated assets. During the year ended December 31, 2019, we recorded a net foreign currency loss of $846, compared to a net foreign currency gain
of $2,708 for the year ended December 31, 2018.

During the three months ended December 31, 2019, we recorded a change in fair value of the warrant liability of $10,731, compared to $nil for the comparative
period in 2018. The revaluation reflected an increase in our share price, causing the fair value of the warrant liability to increase. For the year ended December 31,
2019, we recorded an increase in fair value of the warrant liability of $4,967 compared to $nil for the comparative period in 2018 as the warrants were issued in
2019.

Liquidity and Capital Resources

Cash, working capital and debt

Since inception, we have financed our operations primarily from sales of equity, proceeds from the exercise of warrants and stock options and from interest income
on funds available for investment. Our primary capital needs are for funds to support our scientific research and development activities including staffing, facilities,
manufacturing, preclinical studies, clinical trials, administrative costs and for working capital.

We have experienced operating losses and cash outflows from operations since incorporation, will require ongoing financing in order to continue our research and
development activities and we have not earned significant revenue or reached successful commercialization of our products. Our future operations are dependent
upon  our  ability  to  finance  our  cash  requirements  which  will  allow  us  to  continue  our  research  and  development  activities  and  the  commercialization  of  our
products. There can be no assurance that we will be successful in continuing to finance our operations.

The Company has two series of First Preferred Shares. Series I Non-Voting Convertible First Preferred Shares are non-voting and are convertible into common
shares, on a 30-for-one basis (subject to adjustment), at any time at the option of the holder, subject to certain restrictions on conversion. The Series II Non-Voting
Convertible First Preferred Shares are non-voting and are convertible into common shares, on a one-for-one basis (subject to adjustment), at any time at the option
of the holder, subject to certain restrictions on conversion. Holders may not convert first preferred shares into common shares if, after giving effect to the exercise
of  conversion,  the  holder  and  its  joint  actors  would  have  beneficial  ownership  or  direction  or  control  over  common  shares  in  excess  of  4.99%  of  the  then
outstanding common shares. This limit may be raised at the option of the holder on 61 days' prior written notice: (i) up to 9.99%, (ii) up to 19.99%, subject to
clearance of a personal information form submitted by the holder to the Toronto Stock Exchange, or TSX, and (iii) above 19.99%, subject to approval by the TSX
and shareholder approval. Subsequent to December 31, 2019, all Series I Non-Voting Convertible First Preferred Shares were converted to common shares.

On January 5, 2018, we filed a base shelf prospectus with the British Columbia, Alberta, Manitoba, Ontario and Nova Scotia securities commissions in Canada and
a Form F-10 registration statement with the United States Securities and Exchange Commission, or SEC, that provides that we may sell under the prospectus from
time  to  time  over  the  following  25  months  up  to  $150,000,  in  one  or  more  offerings,  of  common  shares,  First  Preferred  shares,  warrants  to  purchase  common
shares, subscription receipts, or units comprising a combination of common shares, First Preferred shares and/or warrants. We raised capital in February 2019 and
in January 2020 under the short form base shelf prospectus which subsequently expired. 

On June 19, 2018 we filed a prospectus supplement to the base prospectus included in our US registration statement on Form F-10 declared effective on January 8,
2018. We also entered into a sales agreement with Cowen and Company, LLC, or the Agent, pursuant to which we may, at our discretion and from time to time
during the term of the sales agreement, sell, through the Agent, acting as agent and/or principal, such number of common shares of Trillium as would result in
aggregate gross proceeds to us of up to $25,000. Sales of common shares through the Agent, acting as agent, will be made through "at the market" issuances on
Nasdaq at the market price prevailing at the time of each sale, and, as a result, sale prices may vary. This sales agreement was terminated in early 2020.

In February 2019, we completed an underwritten public offering of 6,550,000 common share units and 12,200,000 Series II Non-Voting Convertible First Preferred
Share units, each issued at $0.80 per unit. The gross proceeds  from this offering  were of $15,000 before deducting offering  expenses of $1,117. Each common
share unit is comprised of one common share of the Company and one common share purchase warrant. Each common share purchase warrant will be exercisable
for  one  common  share  at  a  price  of  $0.96  per  common  share  purchase  warrant  for  sixty  months.  Each  preferred  share  unit  is  comprised  of  one  Series  II  First
Preferred Share of the Company and one Series II First Preferred Share purchase warrant. Each Series II First Preferred Share purchase warrant will be exercisable
for one Series II First Preferred Share at a price of $0.96 per Series II First Preferred Share purchase warrant for sixty months.

Management’s Discussion and Analysis

In January 2020, we completed an underwritten public offering for gross proceeds of $116,955 comprised of 41,279,090 common shares and 1,250,000 Series II
Non-Voting Convertible First Preferred Shares, each issued at $2.75 per share.

Our  combined  cash  and  cash  equivalents  and  marketable  securities  balance  at  December  31,  2019  was  $22,666,  compared  to  $33,389  at  December  31,  2018.
Working  capital  at  December  31,  2019  was  $9,765,  compared  to  $25,139  at  December  31,  2018.  The  decrease  in  cash  and  cash  equivalents  and  marketable
securities,  and the  decrease  in working capital  were due mainly  to cash used in operations,  partially  offset  by the  cash received  from  the February  2019 public
offering.

In  November  2019,  we  made  our  final  payment  to  the  Federal  Economic  Development  Agency  for  Southern  Ontario  under  a  non-interest  bearing  contribution
agreement.  The  loan  payable  was  discounted  using  an  estimated  market  interest  rate  of  15%.  Interest  expense  accreted  on  the  discounted  loan  amount  until  it
reached its face value at maturity.

As at December 31, 2019 and 2018, the Company had short-term liabilities of $208 and $nil, and long-term liabilities of $825 and $nil, respectively, for facility
leases.

As at December 31, 2019 and 2018, the Company had a long-term liability of $nil and $95, respectively, related to contingent consideration on the acquisition of
Fluorinov.  On  May  13,  2019,  Trillium  and  former  Fluorinov  shareholders  amended  the  Fluorinov  purchase  agreements  to  remove  the  existing  milestone  and
royalty payments in favour of a revenue sharing arrangement. On the deletion of the milestones from the agreements, the contingent consideration was reduced to
$nil.

As  at  December  31,  2019  and  2018,  the  Company  had  a  short-term  liability  of  $565  and  $nil,  respectively,  related  to  a  retention  provision  for  key  employees.
Retention expense is recognized over the period of service.

Cash flows from operating activities

Cash used in operating activities of $24,908 for the year ended December 31, 2019 was lower than cash used of $30,461 for the year ended December 31, 2018.
The decrease was due mainly to changes in the working capital balances.

Cash flows from investing activities

Cash provided in investing activities totaled $10,128 for the year ended December 31, 2019, compared to cash provided of $23,645 for the year ended December
31, 2018. The change was due mainly to lower net maturities of marketable securities for the year ended December 31, 2019.

Cash flows from financing activities

Cash provided  by financing  activities  totaled  $13,504 for the  year  ended December  31, 2019, compared  to cash used in financing  activities  of $89 for the  year
ended  December  31,  2018.  The  change  was  due  mainly  to  an  underwritten  public  offering  of  common  shares  and  non-voting  convertible  preferred  shares  in
February 2019.

Contractual Obligations and Contingencies

We  enter  into  research,  development  and  license  agreements  in  the  ordinary  course  of  business  where  we  receive  research  services  and  rights  to  proprietary
technologies.  Milestone  and  royalty  payments  that  may  become  due  under  various  agreements  are  dependent  on,  among  other  factors,  clinical  trials,  regulatory
approvals and ultimately the successful development of a new drug, the outcome and timing of which is uncertain.

Under  the  license  agreement  for  SIRPαFc,  we  have  future  contingent  milestones  payable  of  $19  related  to  successful  patent  grants,  $154  and  $231  on  the  first
patient dosed in phase 2 and 3 clinical trials respectively, and regulatory milestones on their first achievement totaling $3,846, and low single digit royalties payable
on net sales.

Management’s Discussion and Analysis

Under a May 2019 amendment agreement, Trillium and the former Fluorinov shareholders share 50% of net revenues on commercialization of any of Fluorinov's
legacy products.

Under  two  agreements  with  Catalent  pursuant  to  which  we  acquired  the  right  to  use  a  proprietary  expression  system  for  the  manufacture  of  two  SIRPαFc
constructs,  we  have  future  contingent  milestones  on  pre-marketing  approval  of  up  to  $875  and  aggregate  sales  milestone  payments  of  up  to  $28,750  for  each
agreement.

We periodically enter into research and license agreements with third parties that include indemnification provisions customary in the industry. These guarantees
generally require us to compensate the other party for certain damages and costs incurred as a result of claims arising from research and development activities
undertaken by us or on our behalf. In some cases, the maximum potential amount of future payments that could be required under these indemnification provisions
could  be  unlimited.  These  indemnification  provisions  generally  survive  termination  of  the  underlying  agreement.  The  nature  of  the  indemnification  obligations
prevents us from making a reasonable estimate of the maximum potential amount we could be required to pay. Historically, we have not made any indemnification
payments under such agreements and no amount has been accrued in our consolidated financial statements with respect to these indemnification obligations.

Other than as disclosed below, we did not have any contractual obligations relating to long-term debt obligations, capital (finance) lease obligations, operating lease
obligations, purchase obligations or other long-term liabilities reflected on our balance sheet as at December 31, 2019:

Share capital issued - year ended December 31, 2019 and to the date of the MD&A

In January 2020, we completed an underwritten public offering for gross proceeds of $116,955 comprised of 41,279,090 common shares and 1,250,000 Series II
Non-Voting Convertible First Preferred Shares, each issued at $2.75 per share.

In February 2019, we completed an underwritten public offering of 6,550,000 common share units and 12,200,000 Series II Non-Voting Convertible First Preferred
Share units, each issued at $0.80 per unit. The gross proceeds from this offering were $15,000, before deducting offering expenses of $1,117. Each common share
unit is comprised of one common share of the Company and one common share purchase warrant. Each common share purchase warrant will be exercisable for one
common share at a price of $0.96 per common share purchase warrant for sixty months. Each preferred share unit is comprised of one Series II First Preferred
Share of the Company and one Series II First Preferred Share purchase warrant. Each Series II First Preferred Share purchase warrant will be exercisable for one
Series II First Preferred Share at a price of $0.96 per Series II First Preferred Share purchase warrant for sixty months. Each purchase warrant has a price protection
feature that resets the exercise price of the warrant under certain conditions including the issuance of common shares, or securities convertible into common shares,
at prices below the exercise price.

In addition, in the event of a "Fundamental Transaction" (as defined in the related warrant agreement, which generally includes any merger with another entity, the
sale, transfer or other disposition of all or substantially all of our assets to another entity, or the acquisition by a person of more than 50% of our common stock),
each warrant holder will have the right up to 90 days after the consummation of the Fundamental Transaction to require us to repurchase the warrant for a purchase
price in cash equal to the Black Scholes value (as calculated under the warrant agreement) of the then remaining unexercised portion of such warrant on the date of
such Fundamental Transaction.

During the year ended December 31, 2019, 7,700,000 Series II First Preferred Shares were converted into 7,700,000 common shares.

Stock Options

The 2018 Stock Option Plan was approved by our shareholders at the annual meeting held on June 1, 2018. Stock options granted are equity-settled, have a vesting
period of between 18 months and four years and have a maximum term of ten years. The total number of common shares available for issuance under the 2018
Stock Option Plan is 3,894,501. As at December 31, 2019, we were entitled to issue an additional 327,856 stock options under the 2018 Stock Option Plan.

During the year ended December 31, 2019, 200,213 unvested stock options were forfeited resulting in a reversal of share-based compensation expense of $851. In
addition, 340,000 unvested stock options were modified to be fully vested resulting in the recognition of $603 of share-based compensation expense in the period
but no additional incremental fair value.

In September 2019, we introduced an Inducement Stock Option Plan, or 2019 Inducement Plan. The 2019 Inducement Plan is used exclusively for the grant of
equity awards to individuals who were not previously an employee or non-employee director of Trillium (or following a bona fide period of non-employment) as
an inducement  material  to  such individual's  entering  into  employment  with Trillium  in accordance  with Nasdaq Listing  Rule 5635(c)(4).  Stock options that  are
granted are equity-settled, have a maximum term of ten years and may be subject to vesting provisions as determined by our board. The total number of common
shares  available  for  issuance  under  the  2019  Inducement  Plan  is 3,000,000. In  connection  with the  appointment  of  Dr. Skvarka  as  Chief  Executive  Officer,  the
board of directors granted to Dr. Skvarka an option to purchase 1,800,000 common shares under the 2019 Inducement Plan. As at December 31, 2019, we were

The board of directors  approved  a Cash-Settled  DSU Plan on November  9, 2016. For the  years  ended December  31, 2019 and 2018, there  were  2,739,587 and
189,393  DSUs  issued,  respectively.  DSUs  were  issued  as  compensation  to  the  Executive  Chair  and  as  director  compensation  for  quarterly  fees  instead  of  cash
payments. The fair values of DSUs under this plan as at December 31, 2019 and 2018 were $2,731 and $623, respectively. For the years ended December 31, 2019
and 2018, the DSU expense, comprised of directors' fees paid and the revaluation of the DSU liability, was an expense of $2,076 and an expense recovery of $207,
respectively.  The number  of DSUs outstanding  as at December  31, 2019 and 2018 were 3,045,821 and 334,982, respectively.  During 2019, 28,748 DSUs were

Trend Information

Historical  patterns  of  expenditures  cannot  be  taken  as  an  indication  of  future  expenditures.  The  amount  and  timing  of  expenditures  and  therefore  liquidity  and
capital resources vary substantially from period to period depending on the number of research and development programs being undertaken at any one time, the
stage  of  the  development  programs,  the  timing  of  significant  expenditures  for  manufacturing,  toxicology  and  pharmacology  studies  and  clinical  trials,  and  the
availability of funding from investors and prospective commercial partners.

The lower net loss in the first quarter of 2018 reflected a higher net foreign currency gain. The increase in net loss in the second quarter of 2018 reflected higher
clinical development expenses and the license agreement amendment payment, partially offset by a net foreign currency gain. The increase in net loss in the third
quarter of 2018 reflected higher clinical development costs. The decrease in net loss in the fourth quarter of 2018 was due mainly to a net foreign currency gain and
change in fair value of DSUs which lowered the general and administrative expenses. The increase in the net loss in the first quarter of 2019 was due mainly to the
change in the net foreign currency gain/loss and higher general and administrative expenses due to the higher DSU revaluation in Q4 2018 which lowered general
and administrative expenses in that period. The change in net loss in Q2 2019 was due mainly to the fluctuation in the revaluation of the warrant liability. In Q3
2019, an impairment loss of $2,952 was recorded to write down the intangible assets acquired in the 2016 Fluorinov acquisition. In Q4 2019, the increase in net
loss was due mainly to the warrant liability revaluation loss of $10,694.

Management’s Discussion and Analysis

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our financial condition, revenues or
expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

Implications of Being an Emerging Growth Company

We are an "emerging growth company" under the US Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and will continue to qualify as an "emerging
growth company" until the earliest to occur of: (a) the last day of the fiscal year during which we have total annual gross revenues of $1.07 billion (as such amount
is indexed for inflation every 5 years by the SEC) or more; (b) the last day of our fiscal year following the fifth anniversary of the date of the first sale of our
common shares pursuant to an effective registration statement under the US Securities Act of 1933 which is December 31, 2020; (c) the date on which we have,
during the previous 3-year period, issued more than $1.0 billion in non-convertible debt; or (d) the date on which we are deemed to be a "large accelerated filer", as
defined in Rule 12b-2 of the US Securities Exchange Act of 1934, or the Exchange Act.

Generally, a company that registers any class of its securities under Section 12 of the Exchange Act is required to include in the second and all subsequent annual
reports filed by it under the Exchange Act, a management report on internal control over financial reporting and, subject to an exemption available to companies
that meet the definition of a "smaller reporting company" in Rule 12b-2 under the Exchange Act, an auditor attestation report on management's assessment of the
company's internal control over financial reporting. However, for so long as we continue to qualify as an emerging growth company, we will be exempt from the
requirement to include an auditor attestation report in our annual reports filed under the Exchange Act, even if we do not qualify as a "smaller reporting company".
In addition, Section 103(a)(3) of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, has been amended by the JOBS Act to provide that, among other
things, auditors of an emerging growth company are exempt from any rules of the Public Company Accounting Oversight Board requiring mandatory audit firm
rotation or a supplement to the auditor's report in which the auditor would be required to provide additional information about the audit and the financial statements
of the company.

Any  US  domestic  issuer  that  is  an  emerging  growth  company  is  able  to  avail  itself  of  the  reduced  disclosure  obligations  regarding  executive  compensation  in
periodic reports and proxy statements, and to not present to its shareholders a non-binding advisory vote on executive compensation, obtain approval of any golden
parachute payments not previously approved, or present the relationship between executive compensation actually paid and our financial performance. So long as
we  are  a  foreign  private  issuer,  we  are  not  subject  to  such  requirements,  and  will  not  become  subject  to  such  requirements  even  if  we  were  to  cease  to  be  an
emerging growth company.

As a reporting issuer under the securities legislation of the Canadian provinces of Ontario, British Columbia, Manitoba, Nova Scotia and Alberta, we are required
to comply with all new or revised accounting standards that apply to Canadian public companies. Pursuant to Section 107(b) of the JOBS Act, an emerging growth
company may elect to utilize an extended transition period for complying with new or revised accounting standards for public companies until such standards apply
to private companies. We have elected not to utilize this extended transition period.

Critical Accounting Estimates

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of
accounting  policies  and  the  reported  amounts  of  assets  and  liabilities,  revenue  and  expenses  and  related  disclosures  of  contingent  assets  and  liabilities.  Actual
results  could  differ  materially  from  these  estimates  and  assumptions.  We  review  our  estimates  and  underlying  assumptions  on  an  ongoing  basis.  Revisions  are
recognized in the period in which the estimates are revised and may impact future periods.

The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements have been set
out below and in note 2 of our annual audited consolidated financial statements for the year ended December 31, 2019.

TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

Going concern

In  the  preparation  of  financial  statements,  management  is  required  to  identify  when  events  or  conditions  indicate  that  significant  doubt  may  exist  about  the
Company's  ability  to  continue  as  a  going  concern.  Significant  doubt  about  the  Company's  ability  to  continue  as  a  going  concern  would  exist  when  relevant
conditions and events, considered in the aggregate, indicate that the Company will not be able to meet its obligations as they become due for a period of at least, but
not limited to, twelve months from the balance sheet date. When the Company identifies conditions or events that raise potential for significant doubt about its
ability to continue as a going concern, the Company considers whether its plans that are intended to mitigate those relevant conditions or events will alleviate the
potential significant doubt.

The Company will require ongoing financing in order to continue research and development activities, as it has not earned significant revenue or reached successful
commercialization of its products. After considering its plans to mitigate the going concern risk, management has concluded that there are no material uncertainties
related to events or conditions that may cast significant doubt upon the Company's ability to continue as a going concern for a period of twelve months from the
balance sheet date.

Impairment of long-lived assets

Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances indicating that the carrying value of the asset may not be
recoverable. For the purpose of measuring recoverable amounts, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-
generating units). The recoverable amount is the higher of an asset's fair value less costs to sell and value in use (being the present value of the expected future cash
flows of the relevant asset or cash-generating unit). An impairment loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable
amount. Management evaluates impairment losses for potential reversals when events or circumstances warrant such consideration.

Valuation of share-based compensation and warrants

Management measures the costs for share-based compensation and warrants using market-based option valuation techniques. Assumptions are made and estimates
are used in applying the valuation techniques. These include estimating the future volatility of the share price, expected dividend yield, expected risk-free interest
rate, future employee turnover rates, future exercise behaviours and corporate performance. Such estimates and assumptions are inherently uncertain. Changes in
these assumptions affect the fair value estimates of share-based compensation and warrants.

The fair value of the warrant liability was calculated using a Black-Scholes fair value model and was then recorded at its relative fair value following an approach
to  allocate  proceeds  to  the  warrant  liability  and  shares.  The  difference  between  the  Black-Scholes  warrant  value  and  the  relative  fair  value  of  the  warrants
represents a discount on issuance that is being amortized over the five-year life of the warrants.

Functional currency

Management considers the determination of the functional currency of the Company a significant judgment. Management has used its judgment to determine the
functional  currency  that  most  faithfully  represents  the  economic  effects  of  the  underlying  transactions,  events  and  conditions  and  considered  various  factors
including  the  currency  of  historical  and  future  expenditures  and  the  currency  in  which  funds  from  financing  activities  are  generated.  A  Company's  functional
currency is only changed when there is a material change in the underlying transactions, events and conditions.

Accounting Policies

TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

Our significant accounting policies are outlined in our annual audited consolidated financial statements for the year ended December 31, 2019. This MD&A should
be read in conjunction with the annual audited consolidated financial statements for the year ended December 31, 2019.

New standards, amendments and interpretations adopted during 2019

IFRS 16 Leases

IFRS 16 Leases sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for all leases under a
single on-balance sheet model, with certain exemptions. The standard includes two recognition exemptions for lessees - leases of "low-value" assets and short-term
leases  with  a  lease  term  of  12  months  or  less.  At  the  commencement  date  of  a  lease,  a  lessee  will  recognize  a  liability  to  make  lease  payments  and  an  asset
representing the right to use the underlying asset during the lease term. Lessees are required to separately recognize the interest expense on the lease liability and
the depreciation expense on the right-of-use asset. The new standard was effective for annual periods beginning on or after January 1, 2019.

We adopted IFRS 16 using the modified retrospective transition approach and elected to use exemptions proposed by the standard on lease contracts for which the
lease term ends within 12 months as of the lease commencement date and the lease contracts where the underlying asset is of low value. We have leases of certain
office equipment (i.e. photocopying machines) that are considered of low value.

The impact of the adoption of IFRS 16 included the recognition of a right-of-use asset of $315 based on the amount equal to the lease liability, adjusted for any
related  prepaid  and  accrued  lease  payments  previously  recognized.  The  lease  liability  of  $579  was  recognized  based  on  the  present  value  of  remaining  lease
payments, discounted using the incremental borrowing rate at the date of initial application. The net result of recognizing the lease liability and right-of-use asset
was an adjustment to the opening deficit of $54.

In addition to the Mississauga facility lease that was transitioned as at January 1, 2019, an office lease for operations in Cambridge, Massachusetts was recognized
under IFRS 16 during the year ended December 31, 2019. This lease resulted in the recognition of a right-of-use asset and corresponding lease liability of $599.

New standards and interpretations not yet effective

Other accounting standards or amendments to existing accounting standards that have been issued, but have future effective dates, are either not applicable or are
not expected to have a significant impact on our consolidated financial statements. 

RISK FACTORS

The following information sets forth material risks and uncertainties that may affect our business, including our future financing and operating results and could
cause our actual results to differ materially from those contained in forward-looking statements we have made in this MD&A. The risks and uncertainties below
are  not  the  only  ones  we  face.  Additional  risks  and  uncertainties  not  presently  known  to  us  or  that  we  believe  to  be  immaterial  may  also  adversely  affect  our
business. Further, if we fail to meet the expectations of the public market in any given period, the market price of our common shares could decline. We operate in
a highly competitive environment that involves significant risks and uncertainties, some of which are outside of our control.

Risks Related to Our Financial Position and Need for Additional Capital

We expect to incur future losses and we may never become profitable.

We have incurred losses of $41,622, $32,866 and $35,225 for the years ended December 31, 2019, 2018 and 2017, respectively, and expect to incur an operating
loss for the year ending December 31, 2020. We have an accumulated deficit since inception through December 31, 2019 of $190,999. We believe that operating
losses will continue as we are planning to incur significant costs associated with the clinical development of our SIRPαFc molecules. Our net losses have had and
will continue to have an adverse effect on, among other things, our shareholders' equity, total assets and working capital. We expect that losses will fluctuate from
quarter to quarter and year to year, and that such fluctuations may be substantial. We cannot predict when we will become profitable, if at all.

TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

We will require additional capital to finance our operations, which may not be available to us on acceptable terms, or at all. As a result, we may not complete
the development and commercialization of our product candidates or develop new product candidates.

As  a  research  and  development  company,  our  operations  have  consumed  substantial  amounts  of  cash  since  inception.  We  expect  to  spend  substantial  funds  to
continue the research, development and testing of our product candidates and to prepare to commercialize products subject to approval of the FDA, in the US and
similar  approvals  in  other  jurisdictions.  We  will  also  require  significant  additional  funds  if  we  expand  the  scope  of  our  current  clinical  plans  or  if  we  were  to
acquire  any  new  assets  and  advance  their  development.  Therefore,  for  the  foreseeable  future,  we  will  have  to  fund  all  of  our  operations  and  development
expenditures from cash on hand, equity or debt financings, through collaborations  with other biotechnology or pharmaceutical  companies or through financings
from other sources. We expect that our existing combined cash and cash equivalents and marketable securities as at December 31, 2019 of $22,666, together with
the  gross  proceeds  of  $116,995  related  to  the  completion  of  an  underwritten  public  offering  in  January  2020,  will  enable  us  to  fund  our  current  operating  plan
requirements for at least the next twelve months. Additional financing will be required to meet our longer term liquidity needs. If we do not succeed in raising
additional  funds  on  acceptable  terms,  we  might  not  be  able  to  complete  preclinical  studies  and  clinical  trials  or  pursue  and  obtain  approval  of  any  product
candidates from the FDA and other regulatory authorities. It is possible that future financing will not be available or, if available, may not be on favorable terms.
The availability of financing will be affected by the achievement of our corporate goals, the results of scientific and clinical research, the ability to obtain regulatory
approvals, the state of the capital markets generally and with particular reference to drug development companies, the status of strategic alliance agreements and
other  relevant  commercial  considerations.  If  adequate  funding  is  not  available,  we  may  be  required  to  delay,  reduce  or  eliminate  one  or  more  of  our  product
development  programs,  or  obtain  funds  through  corporate  partners  or  others  who may  require  us  to  relinquish  significant  rights  to  product  candidates  or  obtain
funds on less favorable terms than we would otherwise accept. To the extent that external sources of capital become limited or unavailable or available on onerous
terms, our intangible assets and our ability to continue our clinical development plans may become impaired, and our assets, liabilities, business, financial condition
and results of operations may be materially or adversely affected.

We currently have no product revenue and will not be able to maintain our operations and research and development without additional funding.

To  date,  we  have  generated  no  product  revenue  and  cannot  predict  when  and  if  we  will  generate  product  revenue.  Our  ability  to  generate  product  revenue  and
ultimately  become  profitable  depends  upon  our  ability,  alone  or  with  partners,  to  successfully  develop  our  product  candidates,  obtain  regulatory  approval,  and
commercialize products, including any of our current product candidates, or other product candidates that we may develop, in-license or acquire in the future. We
do  not  anticipate  generating  revenue  from  the  sale  of  products  for  the  foreseeable  future.  We  expect  our  research  and  development  expenses  to  increase  in
connection with our ongoing activities, particularly as we advance our product candidates through clinical trials.

We may be subject to significant cash payouts in connection with our outstanding warrants in the event of a "Fundamental Transaction".

In  the  event  of  a  "Fundamental  Transaction"  (as  defined  in  the  related  warrant  agreement,  which  generally  includes  any  merger  with  another  entity,  the  sale,
transfer or other disposition of all or substantially all of our assets to another entity, or the acquisition by a person of more than 50% of our common stock), each
warrant holder will have the right up to 90 days after the consummation of the Fundamental Transaction to require us to repurchase the warrant for a purchase price
in cash equal to the Black Scholes value (as calculated under the warrant agreement) of the then remaining unexercised portion of such warrant on the date of such
Fundamental Transaction, which may materially adversely affect our financial condition and/or results of operations. There can be no assurance that in the event of
a Fundamental Transaction we will be able to sufficiently compensate the holders of the warrants in accordance with the terms thereof. The warrant provisions may
delay or prevent our ability to undertake a strategic transaction that may be beneficial to shareholders. These restrictions may also adversely affect the market price
of our common shares.

Management’s Discussion and Analysis

We are exposed to the financial risk related to the fluctuation of foreign exchange rates and the degrees of volatility of those rates.

We may be adversely affected by foreign currency fluctuations. To date, we have been primarily funded through issuances of equity, proceeds from the exercise of
warrants and stock options and from interest income on funds available for investment, which are denominated both in Canadian and US dollars. Also, a significant
portion of our expenditures are in US dollars, and we are therefore subject to foreign currency fluctuations which may, from time to time, impact our financial
position and results of operations.

Risks Related to Our Business and Our Industry

Our prospects depend on the success of our product candidates which are at early stages of development, and we may not generate revenue for several years, if
at all, from these products.

Given the early stage of our product development, we can make no assurance that our research and development programs will result in regulatory approval or
commercially  viable  products.  To  achieve  profitable  operations,  we,  alone  or  with  others,  must  successfully  develop,  gain  regulatory  approval,  and  market  our
future  products.  We  currently  have  no  products  that  have  been  approved  by  the  FDA,  Health  Canada,  or  HC,  or  any  similar  regulatory  authority.  To  obtain
regulatory approvals for our product candidates being developed and to achieve commercial success, clinical trials must demonstrate that the product candidates are
safe for human use and that they demonstrate efficacy. While we have commenced clinical trials for SIRPαFc, we have not yet completed later stage clinical trials
for any of our product candidates.

Many product candidates never reach the stage of clinical testing and even those that do have only a small chance of successfully completing clinical development
and gaining regulatory approval. Product candidates may fail for a number of reasons, including, but not limited to, being unsafe for human use or due to the failure
to provide therapeutic benefits equal to or better than the standard of treatment at the time of testing. Unsatisfactory results obtained from a particular study relating
to a research and development program may cause us or our collaborators to abandon commitments to that program.

The early stage of our product development makes it particularly uncertain whether any of our product development efforts will prove to be successful and meet
applicable regulatory requirements, and whether any of our product candidates will receive the requisite regulatory approvals, be capable of being manufactured at
a reasonable cost or be successfully marketed. If we are successful in developing our current and future product candidates into approved products, we will still
experience many potential obstacles such as the need to develop or obtain manufacturing, marketing and distribution capabilities. If we are unable to successfully
commercialize any of our products, our financial condition and results of operations may be materially and adversely affected.

Positive results from preclinical and early clinical research of TTI-621 and TTI-622 are not necessarily predictive of the results of later clinical trials of TTI-
621  or  TTI-622.  If  we  cannot  replicate  the  positive  results  from  preclinical  and  early  clinical  research  in  our  later  clinical  trials,  we  may  be  unable  to
successfully develop, obtain regulatory approval for and commercialize TTI-621 or TTI-622.

Positive results of preclinical and early clinical research of TTI-621 and TTI-622 may not be indicative of the results that will be obtained in later-stage clinical
trials.  For  example,  we  have  focused  our  near-term  clinical  product  development  on  T-cell  malignancies  based  on  preliminary  results  of  our  intravenous  and
intratumoral trials. There can be no assurance that the preliminary results we have seen in a small number of T-cell lymphoma patients will be reproducible in a
larger population of patients. We can make no assurance that any future studies, if undertaken, will yield favorable results.

Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later-stage clinical trials after achieving positive results
in early-stage development, and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things, preclinical
findings  made  while  clinical  trials  were  underway  or  safety  or  efficacy  observations  made  in  clinical  trials,  including  previously  unreported  adverse  events.
Moreover, preclinical  and clinical data are often susceptible to varying interpretations  and analyses, and many companies that believed their product candidates
performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA approval. If we fail to produce positive results in our clinical trials
of  TTI-621  or  TTI-622,  the  development  timeline  and  regulatory  approval  and  commercialization  prospects  for  our  leading  product  candidates,  and,
correspondingly, our business and financial prospects, would be materially adversely affected.

Management’s Discussion and Analysis

We  rely  and  will  continue  to  rely  on  third  parties  to  plan,  conduct  and  monitor  our  preclinical  studies  and  clinical  trials,  and  their  failure  to  perform  as
required could cause substantial harm to our business.

We rely and will continue to rely on third parties to conduct a significant portion of our preclinical and clinical development activities. Preclinical activities include
in vivo studies providing access to specific disease models, pharmacology and toxicology studies, and assay development. Clinical development activities include
trial design, regulatory submissions, clinical patient and site recruitment, clinical trial monitoring, clinical data management and analysis, safety monitoring and
project management. If there is any dispute or disruption in our relationship with third parties, or if they are unable to provide quality services in a timely manner
and at a feasible cost, our active development programs will face delays. Further, if any of these third parties fails to perform as we expect or if their work fails to
meet regulatory requirements, our testing could be delayed, cancelled or rendered ineffective.

We rely  on contract  manufacturers  over whom we have limited  control. If we are subject  to quality,  cost or delivery  issues with the preclinical  and clinical
grade materials supplied by contract manufacturers, our business operations could suffer significant harm.

We have limited manufacturing experience and rely on contract manufacturing organizations, or CMOs to manufacture our product candidates for larger preclinical
studies  and  clinical  trials.  We  rely  on  CMOs  for  manufacturing,  filling,  packaging,  storing  and  shipping  of  drug  product  in  compliance  with  current  Good
Manufacturing  Practice,  or  cGMP,  regulations  applicable  to  our  products.  The  FDA  ensures  the  quality  of  drug  products  by  carefully  monitoring  drug
manufacturers' compliance with cGMP regulations. The cGMP regulations for drugs contain minimum requirements for the methods, facilities and controls used in
manufacturing, processing and packaging of a drug product.

We contracted with Catalent for the manufacture of the SIRPαFc protein to supply drug substance for our clinical trials. The manufacture of recombinant proteins
uses  well  established  processes  including  a  protein  expression  system.  Catalent  is  producing  SIRPαFc  using  their  proprietary  GPEx®  expression  system.  We
believe that Catalent has the capacity, the systems, and the experience to supply SIRPαFc for our current clinical trials and we may consider using Catalent for
manufacturing  for  later  clinical  trials.  However,  since  the  Catalent  manufacturing  facility  where  SIRPαFc  is  being  produced  does  not  support  commercial
manufacturing, it has not yet been inspected by the FDA. Any manufacturing failures, delays or compliance issues could cause delays in the conduct of SIRPαFc
preclinical studies and clinical trials.

There can be no assurances that CMOs will be able to meet our timetable  and requirements. We have not contracted with alternate  suppliers for SIRPαFc drug
substance production in the event Catalent is unable to scale up production, or if Catalent otherwise experiences any other significant problems. If we are unable to
arrange for alternative third-party manufacturing sources on commercially reasonable terms or in a timely manner, we may be delayed in the development of our
product  candidates.  Further,  CMOs  must  operate  in  compliance  with  cGMP  and  failure  to  do  so  could  result  in,  among  other  things,  the  disruption  of  product
supplies. Our dependence upon third parties for the manufacture  of our products may adversely affect our profit margins and our ability to develop and deliver
products on a timely and competitive basis.

We require commercial scale and quality manufactured product to be available for pivotal or registration clinical trials. If we do not have commercial grade
drug supply when needed, we may face delays in initiating or completing pivotal trials and our business operations could suffer significant harm.

To date, our product has been manufactured in small quantities for preclinical studies and clinical trials by third-party manufacturers. In order to commercialize our
product,  we need  to manufacture  commercial  quality  drug  supply  for use  in  registration  clinical  trials.  Most,  if not  all,  of  the  clinical  material  used  in  phase  3/
pivotal/ registration studies must be derived from the defined commercial process including scale, manufacturing site, process controls and batch size. If we have
not  scaled  up  and  validated  the  commercial  production  of  our  product  prior  to  the  commencement  of  pivotal  clinical  trials,  we may  have  to  employ  a  bridging
strategy during the trial to demonstrate equivalency of early stage material to commercial drug product, or potentially delay the initiation or completion of the trial
until  drug  supply  is  available.  The  manufacturing  of  commercial  quality  drug  product  requires  significant  efforts  including,  but  not  limited  to  scale-up  of
production to anticipated commercial scale, process characterization and validation, analytical method validation, identification of critical process parameters and
product quality attributes, multiple process performance and validation runs, has long lead times and is very expensive. If we do not have commercial drug supply
available when needed for pivotal clinical trials, our regulatory and commercial progress may be delayed and we may incur increased product development cost.
This may have a material adverse effect on our business, financial condition and prospects, and may delay marketing of the product.

Management’s Discussion and Analysis

If  clinical  trials  of  our  product  candidates  fail  to  demonstrate  safety  and  efficacy  to  the  satisfaction  of  regulatory  authorities  or  do  not  otherwise  produce
positive  results,  we  would  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the  development  and
commercialization of our product candidates.

Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  our  product  candidates,  we  must  conduct  preclinical  studies  in  animals  and
extensive  clinical  trials  in  humans  to  demonstrate  the  safety  and  efficacy  of  the  product  candidates.  Clinical  testing  is  expensive  and  difficult  to  design  and
implement, can take many years to complete and has uncertain outcomes. The outcome of preclinical studies and early clinical trials may not predict the success of
later clinical trials, and interim results of a clinical trial do not necessarily predict final results. A number of companies in the pharmaceutical and biotechnology
industries have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety profiles, notwithstanding promising results in
earlier trials. We do not know whether the clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market
any of our product candidates in any jurisdiction. A product candidate may fail for safety or efficacy reasons at any stage of the testing process. A major risk we
face is the possibility that none of our product candidates under development will successfully gain market approval from the FDA or other regulatory authorities,
resulting in us being unable to derive any commercial revenue from them after investing significant amounts of capital in their development.

If we experience delays in clinical testing, we will be delayed in commercializing our product candidates, and our business may be substantially harmed.

We  cannot  predict  whether  any  clinical  trials  will  begin  as  planned,  will  need  to  be  restructured,  or  will  be  completed  on  schedule,  or  at  all.  Our  product
development costs will increase if we experience delays in clinical testing. Significant clinical trial delays could shorten any periods during which we may have the
exclusive  right  to  commercialize  our  product  candidates  or  allow  our  competitors  to  bring  products  to  market  before  us,  which  would  impair  our  ability  to
successfully commercialize our product candidates and may harm our financial condition, results of operations and prospects. The commencement and completion
of clinical trials for our products may be delayed for a number of reasons, including delays related, but not limited, to:

failure by regulatory authorities to grant permission to proceed or placing the clinical trial on hold;
patients failing to enroll or remain in our trials at the rate we expect;
suspension or termination of clinical trials by regulators for many reasons, including concerns about patient safety or failure of our CMOs to comply with
cGMP requirements;
any changes to our manufacturing process that may be necessary or desired;
delays or failure to obtain clinical supply from CMOs of our products necessary to conduct clinical trials;
product candidates demonstrating a lack of safety or efficacy during clinical trials;
patients choosing an alternative treatment for the indications for which we are developing any of our product candidates or participating in competing
clinical trials;
patients failing to complete clinical trials due to dissatisfaction with the treatment, side effects or other reasons;
reports of clinical testing on similar technologies and products raising safety and/or efficacy concerns;

- 26 -

 
TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

competing clinical trials and scheduling conflicts with participating clinicians;
clinical investigators not performing our clinical trials on their anticipated schedule, dropping out of a trial, or employing methods not consistent with the
clinical trial protocol, regulatory requirements or other third parties not performing data collection and analysis in a timely or accurate manner;
failure of our contract research organizations, or CROs, to satisfy their contractual duties or meet expected deadlines;
inspections of clinical trial sites by regulatory authorities or Institutional Review Boards, or IRBs, or ethics committees finding regulatory violations that
require us to undertake corrective action, resulting in suspension or termination of one or more sites or the imposition of a clinical hold on the entire study;
one or more IRBs or ethics committees rejecting, suspending or terminating the study at an investigational site, precluding enrollment of additional
subjects, or withdrawing its approval of the trial; or
failure to reach agreement on acceptable terms with prospective clinical trial sites.

Our product development costs will increase if we experience delays in testing or approval or if we need to perform more or larger clinical trials than planned.
Additionally, changes in regulatory requirements and policies may occur, and we may need to amend study protocols to reflect these changes. Amendments may
require  us  to  resubmit  our  study  protocols  to  regulatory  authorities  or  IRBs  or  ethics  committees  for  re-examination,  which  may  impact  the  cost,  timing  or
successful  completion  of  that  trial.  Delays  or  increased  product  development  costs  may  have  a  material  adverse  effect  on  our  business,  financial  condition  and
prospects.

We may not achieve our publicly announced milestones according to schedule, or at all.

From  time  to  time,  we  may  announce  the  timing  of  certain  events  we  expect  to  occur,  such  as  the  anticipated  timing  of  results  from  our  clinical  trials.  These
statements are forward-looking and are based on the best estimates of management at the time relating to the occurrence of such events. However, the actual timing
of such events may differ from what has been publicly disclosed. The timing of events such as initiation or completion of a clinical trial, filing of an application to
obtain  regulatory  approval,  or  announcement  of  additional  clinical  trials  for  a  product  candidate  may  ultimately  vary  from  what  is  publicly  disclosed.  These
variations in timing may occur as a result of different events, including the nature of the results obtained during a clinical trial or during a research phase, timing of
the completion of clinical trials, problems with a CMO or a CRO or any other event having the effect of delaying the publicly announced timeline. We undertake
no obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, except as otherwise required
by law. Any variation in the timing of previously announced milestones could have a material adverse effect on our business plan, financial condition or operating
results and the trading price of our common shares.

We may not be able to file INDs to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to
proceed in a timely manner, or at all.

Prior to commencing clinical trials in the United States for any of our product candidates, we may be required to have an allowed IND for each product candidate
and to file additional INDs prior to initiating any additional clinical trials for SIRPαFc. We believe that the data from previous studies will support the filing of
additional INDs, to enable us to undertake additional clinical studies as we have planned. However, submission of an IND may not result in the FDA allowing
further  clinical  trials  to  begin  and,  once  begun,  issues  may  arise  that  will  require  us  to  suspend  or  terminate  such  clinical  trials.  Additionally,  even  if  relevant
regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND, these regulatory authorities may change their requirements
in the future. Failure to submit or have effective INDs and commence or continue clinical programs will significantly limit our opportunity to generate revenue.

If we have difficulty enrolling patients in clinical trials, the completion of the trials may be delayed or cancelled.

As our product candidates advance from preclinical testing to clinical testing, and then through progressively larger and more complex clinical trials, we will need
to enroll an increasing number of patients that meet our eligibility criteria. There is significant competition for recruiting cancer patients in clinical trials, and we
may be unable to enroll the patients we need to complete clinical trials on a timely basis or at all. The factors that affect our ability to enroll patients are largely
uncontrollable and include, but are not limited to, the following:

- 27 -

 
TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

size and nature of the patient population;
eligibility and exclusion criteria for the trial;
design of the study protocol;
competition with other companies for clinical sites or patients;
the perceived risks and benefits of the product candidate under study;
the patient referral practices of physicians; and
the number, availability, location and accessibility of clinical trial sites.

If we are unable to successfully develop companion diagnostics for our therapeutic product candidates, or experience significant delays in doing so, we may not
achieve marketing approval or realize the full commercial potential of our therapeutic product candidates.

We  may  develop  companion  diagnostics  for  our  therapeutic  product  candidates.  We  expect  that,  at  least  in  some  cases,  regulatory  authorities  may  require  the
development and regulatory approval of a companion diagnostic as a condition to approving our therapeutic product candidates. We have limited experience and
capabilities in developing or commercializing diagnostics and plan to rely in large part on third parties to perform these functions. We have not begun to develop
companion diagnostics for any of our therapeutic product candidates.

Companion  diagnostics  are  subject  to  regulation  by  the  FDA,  HC,  and  comparable  foreign  regulatory  authorities  as  medical  devices  and  may  require  separate
regulatory approval or clearance prior to commercialization. If we, or any third parties that we engage to assist us, are unable to successfully develop companion
diagnostics for our therapeutic product candidates, or experience delays in doing so, our business may be substantially harmed.

Regulatory  approval  processes  are  lengthy,  expensive  and  inherently  unpredictable.  Our  inability  to  obtain  regulatory  approval  for  our  product  candidates
would substantially harm our business.

Our development and commercialization activities and product candidates are significantly regulated by a number of governmental entities, including the FDA,
HC, and comparable authorities in other countries. Regulatory approvals are required prior to each clinical trial and we may fail to obtain the necessary approvals to
commence  or  continue  clinical  testing.  We  must  comply  with  regulations  concerning  the  manufacture,  testing,  safety,  effectiveness,  labeling,  documentation,
advertising, and sale of products and product candidates and ultimately must obtain regulatory approval before we can commercialize a product candidate. The time
required to obtain approval by such regulatory authorities is unpredictable but typically takes many years following the commencement of preclinical studies and
clinical trials. Any analysis of data from clinical activities we perform is subject to confirmation and interpretation by regulatory authorities, which could delay,
limit or prevent regulatory approval. Even if we believe results from our clinical trials are favorable to support the marketing of our product candidates, the FDA or
other regulatory authorities may disagree. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change
during  the  course  of  a  product  candidate's  clinical  development  and  may  vary  among  jurisdictions.  We  have  not  obtained  regulatory  approval  for  any  product
candidate and it is possible that none of our existing product candidates or any future product candidates will ever obtain regulatory approval.

We could fail to receive regulatory approval for our product candidates for many reasons, including, but not limited to:

disagreement with the design or implementation of our clinical trials;
failure to demonstrate that a product candidate is safe and effective for its proposed indication;
failure of clinical trials to meet the level of statistical significance required for approval;
failure to demonstrate that a product candidate's clinical and other benefits outweigh its safety risks;
disagreement with our interpretation of data from preclinical studies or clinical trials;
the insufficiency of data collected from clinical trials of our product candidates to support the submission and filing of a biologic license application, or
BLA, or other submission to obtain regulatory approval;
deficiencies in the manufacturing processes or the failure of facilities of CMOs with whom we contract for clinical and commercial supplies to pass a pre-
approval inspection; or

- 28 -

 
TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

changes in the approval policies or regulations that render our preclinical and clinical data insufficient for approval.

A regulatory authority may require more information, including additional preclinical or clinical data to support approval, which may delay or prevent approval and
our commercialization plans, or we may decide to abandon the development program. If we were to obtain approval, regulatory authorities may approve any of our
product candidates for fewer or more limited indications than we request, may grant approval contingent on the performance of costly post-marketing clinical trials,
or  may  approve  a  product  candidate  with  a  label  that  does  not  include  the  labeling  claims  necessary  or  desirable  for  the  successful  commercialization  of  that
product candidate. Moreover, depending on any safety issues associated with our product candidates that garner approval, the FDA may impose a risk evaluation
and mitigation strategy, thereby imposing certain restrictions on the sale and marketability of such products.

We face competition from other biotechnology and pharmaceutical companies and our financial condition and operations will suffer if we fail to effectively
compete.

The  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant  technological  change.  Our  competitors  include
large, well-established pharmaceutical companies, biotechnology companies, and academic and research institutions developing cancer therapeutics for the same
indications we are targeting and competitors with existing marketed therapies. Many other companies are developing or commercializing therapies to treat the same
diseases or indications for which our product candidates may be useful. Although there are no approved therapies that specifically target the CD47 pathway, some
competitors use therapeutic approaches that may compete directly with our product candidates. For example, SIRPαFc is in direct competition with CD47 blocking
antibodies from Forty Seven Inc., Celgene Corporation, TG Therapeutics and others.

Many  of  our  competitors  have  substantially  greater  financial,  technical  and  human  resources  than  we  do  and  have  significantly  greater  experience  than  us  in
conducting preclinical testing and human clinical trials of product candidates, scaling up manufacturing operations and obtaining regulatory approvals of products.
Accordingly, our competitors may succeed in obtaining regulatory approval for products more rapidly than we do. Our ability to compete successfully will largely
depend on:

the efficacy and safety profile of our product candidates relative to marketed products and other product candidates in development;
our ability to develop and maintain a competitive position in the product categories and technologies on which we focus;
the time it takes for our product candidates to complete clinical development and receive marketing approval;
our ability to obtain required regulatory approvals;
our ability to commercialize any of our product candidates that receive regulatory approval;
our ability to establish, maintain and protect intellectual property rights related to our product candidates; and
acceptance of any of our product candidates that receive regulatory approval by physicians and other healthcare providers and payers.

If we are not able to compete effectively against our current and future competitors, our business will not grow and our financial condition and operations will
substantially suffer.

We  heavily  rely  on  the  capabilities  and  experience  of  our  key  executives  and  scientists  and  the  loss  of  any  of  them  could  affect  our  ability  to  develop  our
products.

Our  success  will  depend  in  large  measure  on  the  ability,  expertise,  judgement,  discretion,  integrity  and  good  faith  of  our  key  executives  and  other  personnel
conducting  our  business.  Our  management  structure  has  undergone  changes  in  2019  due  to  the  resignation  in  April  2019  of  our  former  President  and  Chief
Executive Officer and director, and the appointment in September 2019 of our new President and Chief Executive Officer and director, Dr. Jan Skvarka. Dr. Robert
L. Kirkman, M.D., the Chair of the Board is currently acting as Executive Chair, and Dr. Robert Uger, the current Chief Scientific Officer, served as a director from
April 30, 2019 to February 6, 2020. We have employment agreements with Dr. Skvarka, Dr. Kirkman and Dr. Uger, and other key members of our staff, and in
May 2019 the Board put agreements in place for key executives and staff to encourage retention, although such agreements do not guarantee their retention. This
transition may cause some disruption to our business, and may have an adverse effect on our business, operating results or financial condition.

- 29 -

 
TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

We also depend on our scientific and clinical collaborators and advisors, all of whom have outside commitments that may limit their availability to us. In addition,
we  believe  that  our  future  success  will  depend  in  large  part  upon  our  ability  to  attract  and  retain  highly  skilled  scientific,  managerial,  medical,  manufacturing,
clinical, commercial and regulatory personnel, particularly as we expand our activities and seek regulatory approvals for clinical trials. We enter into agreements
with our scientific and clinical collaborators and advisors, key opinion leaders and academic partners in the ordinary course of our business. We also enter into
agreements with physicians and institutions who will recruit patients into our clinical trials on our behalf in the ordinary course of our business. Notwithstanding
these arrangements, we face significant competition for these types of personnel from other companies, research and academic institutions, government entities and
other  organizations.  We  cannot  predict  our  success  in  hiring  or retaining  the  personnel  we require  for  continued  growth.  The  loss  of  the  services  of  any  of  our
executive officers or other key personnel could potentially harm our business, operating results or financial condition.

Our  employees  may  engage  in  misconduct  or  other  improper  activities,  including  noncompliance  with  regulatory  standards  and  requirements,  which  could
have a material adverse effect on our business.

We  are  exposed  to  the  risk  of  employee  fraud  or  other  misconduct.  Misconduct  by  employees  could  include  failures  to  comply  with  FDA  regulations,  provide
accurate information to the FDA, comply with manufacturing standards we have established, comply with federal and state healthcare fraud and abuse laws and
regulations, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the
healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing, and other abusive practices. These laws and
regulations  may  restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,  sales  commission,  customer  incentive  programs  and  other
business arrangements.  Employee  misconduct  could also involve  the improper  use of information  obtained in the course  of clinical  trials,  which could result  in
regulatory sanctions and serious harm to our reputation. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting
our rights, those actions could have a substantial impact on our business and results of operations, including the imposition of substantial fines or other sanctions.

We may expand our business through the acquisition of companies or businesses or by entering into collaborations or by in-licensing product candidates, each
of which could disrupt our business and harm our financial condition.

We  have  in  the  past  and  may  in  the  future  seek  to  expand  our  pipeline  and  capabilities  by  acquiring  one  or  more  companies  or  businesses,  entering  into
collaborations, or in-licensing one or more product candidates. Acquisitions, collaborations and in-licenses involve numerous risks, including, but not limited to:

substantial cash expenditures;
technology development risks;
potentially dilutive issuances of equity securities;
incurrence of debt and contingent liabilities, some of which may be difficult or impossible to identify at the time of acquisition;
difficulties in assimilating the operations of the acquired companies;
potential disputes regarding contingent consideration;
diverting our management's attention away from other business concerns;
entering markets in which we have limited or no direct experience; and
potential loss of our key employees or key employees of the acquired companies or businesses.

- 30 -

 
TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

We  have  experience  in  making  acquisitions,  entering  collaborations,  and  in-licensing  product  candidates,  however,  we  cannot  provide  assurance  that  any
acquisition, collaboration or in-license will result in short-term or long-term benefits to us. We may incorrectly judge the value or worth of an acquired company or
business or in-licensed product candidate. In addition, our future success would depend in part on our ability to manage the rapid growth associated with some of
these acquisitions, collaborations and in-licenses. We cannot provide assurance that we would be able to successfully combine our business with that of acquired
businesses,  manage  a  collaboration  or  integrate  in-licensed  product  candidates.  Furthermore,  the  development  or  expansion  of  our  business  may  require  a
substantial capital investment by us.

Negative results from clinical  trials or studies of others and adverse safety events involving the targets of our products may have an adverse impact on our
future commercialization efforts.

From time to time, studies or clinical trials on various aspects of biopharmaceutical products are conducted by academic researchers, competitors or others. The
results of these studies or trials, when published, may have a significant effect on the market for the biopharmaceutical product that is the subject of the study. The
publication of negative results of studies or clinical trials or adverse safety events related to our product candidates, or the therapeutic areas in which our product
candidates compete, could adversely affect our share price and our ability to finance future development of our product candidates, and our business and financial
results could be materially and adversely affected.

We face the risk of product liability claims, which could exceed our insurance coverage and produce recalls, each of which could deplete our cash resources.

We are exposed to the risk of product liability claims alleging that use of our product candidates caused an injury or harm. These claims can arise at any point in the
development,  testing,  manufacture,  marketing  or  sale  of  our  product  candidates  and  may  be  made  directly  by  patients  involved  in  clinical  trials  of  our  product
candidates, by consumers or healthcare providers or by individuals, organizations or companies selling our products. Product liability claims can be expensive to
defend, even if the product or product candidate did not actually cause the alleged injury or harm.

Insurance covering product liability claims becomes increasingly expensive as a product candidate moves through the development pipeline to commercialization.
We currently maintain clinical trial liability insurance coverage of $10,000. However, there can be no assurance that such insurance coverage is or will continue to
be adequate or available to us at a cost acceptable to us or at all. We may choose or find it necessary under our collaborative agreements to increase our insurance
coverage  in  the  future.  We  may  not  be  able  to  secure  greater  or  broader  product  liability  insurance  coverage  on  acceptable  terms  or  at  reasonable  costs  when
needed. Any liability for damages resulting from a product liability claim could exceed the amount of our coverage, require us to pay a substantial monetary award
from  our  own  cash  resources  and  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  Moreover,  a  product  recall,  if
required,  could  generate  substantial  negative  publicity  about  our  products  and  business,  inhibit  or  prevent  commercialization  of  other  products  and  product
candidates or negatively impact existing or future collaborations.

If we are unable to maintain product liability insurance required by our third parties, the corresponding agreements would be subject to termination, which
could have a material adverse impact on our operations.

Some of our licensing and other agreements with third parties require or might require us to maintain product liability insurance. If we cannot maintain acceptable
amounts of coverage on commercially reasonable terms in accordance with the terms set forth in these agreements, the corresponding agreements would be subject
to termination, which could have a material adverse impact on our operations.

Risks Related to Intellectual Property

If  we  are  unable  to  adequately  protect  and  enforce  our  intellectual  property,  our  competitors  may  take  advantage  of  our  development  efforts  or  acquired
technology and compromise our prospects of marketing and selling our key products.

We control two main patent families relating to SIRPα. One family relates to the use of SIRPα to treat cancer. The other family relates to our drug as a composition
of matter, SIRPαFc. We have also filed for patent protection covering additional inventions relating to SIRPα, including anti-cancer drug combination therapies
that utilize SIRPαFc, and biomarkers that identify SIRPαFc responders. Our success will depend in part upon our ability to protect our intellectual property and
proprietary  technologies  and  upon  the  nature  and  scope  of  the  intellectual  property  protection  we  receive.  For  example,  some  of  our  patent  portfolio  covers
primarily  methods  of  medical  use  but  not  compositions  of  matter.  The  ability  to  compete  effectively  and  to  achieve  partnerships  will  depend  on  our  ability  to
develop and maintain proprietary aspects of our technology and to operate without infringing on the proprietary rights of others. The presence of such proprietary
rights of others could severely limit our ability to develop and commercialize our products, to conduct our existing research and could require financial resources to
defend litigation, which may be in excess of our ability to raise such funds. There is no assurance that our pending patent applications or any that we intend to
acquire will be approved in a form that will be sufficient to protect our proprietary technology and gain or keep any competitive advantage that we may have or,
once approved, will be upheld in any post-grant proceedings brought by any third parties.

The patent positions of pharmaceutical companies can be highly uncertain and involve complex legal, scientific and factual questions for which important legal
principles  remain  unresolved.  Patents  issued  to  us  or  our  respective  licensors  may  be  challenged,  invalidated  or  circumvented.  To  the  extent  our  intellectual
property, including licensed intellectual property, offers inadequate protection, or is found to be invalid or unenforceable, we are exposed to a greater risk of direct
competition.  If  our  intellectual  property  does  not  provide  adequate  protection  against  our  competitors'  products,  our  competitive  position  could  be  adversely
affected, as could our business, financial condition and results of operations. Both the patent application process and the process of managing patent disputes can be
time consuming and expensive, and the laws of some foreign countries may not protect our intellectual property rights to the same extent as do the laws of Canada
and the United States.

We will be able to protect our intellectual property from unauthorized use by third parties only to the extent that our proprietary technologies, key products, and any
future products are covered by valid and enforceable intellectual property rights including patents or are effectively maintained as trade secrets, and provided we
have the funds to enforce our rights, if necessary.

If we lose our licenses from third-party owners we may be unable to continue a substantial part of our business.

We are party to licenses that give us rights to intellectual property that is necessary or useful for a substantial part of our business. Pursuant to our exclusive license
agreement with the University Health Network and the Hospital for Sick Children under which we license certain patent rights for our key products and their uses,
we are required to use commercially reasonable efforts to commercialize products based on the licensed rights and pay milestone payments, royalties on net sales,
and an annual maintenance fee.

We  have  also  entered  into  agreements  allowing  us  to  manufacture  SIRPαFc using  Catalent's  proprietary  GPEx®  expression  system.  The  consideration  includes
payments at the time we successfully reach a series of development and sales milestones. We may also enter into licenses in the future to access additional third-
party intellectual property.

If  we  fail  to  pay  annual  maintenance  fees,  development  and  sales  milestones,  or  it  is  determined  that  we  did  not  use  commercially  reasonable  efforts  to
commercialize licensed products, we could lose our licenses which could have a material adverse effect on our business and financial condition.

TRILLIUM THERAPEUTICS INC.

Management’s Discussion and Analysis

We may require additional third-party licenses to effectively develop and manufacture our key products and are currently unable to predict the availability or
cost of such licenses.

A substantial number of patents have already been issued to other biotechnology and pharmaceutical companies. To the extent that valid third-party patent rights
cover our products or services, we or our strategic collaborators would be required to seek licenses from the holders of these patents in order to manufacture, use or
sell these products and services, and payments under them would reduce our profits from these products and services. We are currently unable to predict the extent
to which we may wish or be required to acquire rights under such patents, the availability and cost of acquiring such rights, and whether a license to such patents
will be available on acceptable terms or at all. There may be patents in the US or in foreign countries or patents issued in the future that are unavailable to license
on acceptable terms. Our inability to obtain such licenses may hinder or eliminate our ability to manufacture and market our products.

Changes in patent law and its interpretation could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

As  is  the  case  with  other  biotechnology  and  pharmaceutical  companies,  our  success  is  heavily  dependent  on  intellectual  property  rights,  particularly  patents.
Obtaining  and  enforcing  patents  in  the  biopharmaceutical  industry  involves  technological  and  legal  complexity,  and  obtaining  and  enforcing  biopharmaceutical
patents is costly, time-consuming and inherently uncertain. The US Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of
patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing uncertainty with regard
to  our  and  our  licensors'  or  collaborators'  ability  to  obtain  patents  in  the  future,  this  combination  of  events  has  created  uncertainty  with  respect  to  the  value  of
patents,  once  obtained.  Depending  on  decisions  by  the  US  Congress,  the  federal  courts,  and  the  US  Patent  and  Trademark  Office,  or  USPTO,  the  laws  and
regulations governing patents could change in unpredictable  ways that would weaken our and our licensors' or collaborators'  ability to obtain new patents or to
enforce existing patents and patents we and our licensors or collaborators may obtain in the future.

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our and our licensors' or collaborators' patent applications
and  the  enforcement  or  defense  of  our  or  our  licensors'  or  collaborators'  issued  patents.  On  September  16,  2011,  the  Leahy-Smith  America  Invents  Act,  or  the
Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a number of significant changes to US patent law. These include provisions that affect the
way patent applications are prosecuted and may also affect patent litigation. The USPTO 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,  only
became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. However, the
Leahy-Smith  Act  and  its  implementation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  or  our  licensors'  or  collaborators'  patent
applications  and  the  enforcement  or  defense  of  our  or  our  licensors'  or  collaborators'  issued  patents,  all  of  which  could  have  a  material  adverse  effect  on  our
business and financial condition.

Litigation  regarding  patents,  patent  applications,  and  other  proprietary  rights  may  be  expensive,  time  consuming  and  cause  delays  in  the  development  and
manufacturing of our key products.

Our success will depend in part on our ability to operate without infringing the proprietary rights of third parties. The pharmaceutical industry is characterized by
extensive patent litigation. Other parties may have, or obtain in the future, patents and allege that the use of our technologies infringes these patent claims or that
we are employing their proprietary technology without authorization.

In addition, third parties may challenge or infringe upon our existing or future patents. Proceedings involving our patents or patent applications or those of others
could result in adverse decisions regarding:

the patentability of our inventions relating to our key products; and/or
the enforceability, validity, or scope of protection offered by our patents relating to our key products.

Management’s Discussion and Analysis

If we are unable to avoid infringing the patent rights of others, we may be required to seek a license, defend an infringement action, or challenge the validity of the
patents  in  court.  Regardless  of  the  outcome,  patent  litigation  is  costly  and  time  consuming.  In  some  cases,  we may  not  have  sufficient  resources  to  bring  these
actions to a successful conclusion. In addition, if we do not obtain a license, develop or obtain non-infringing technology, fail to defend an infringement action
successfully or have infringed patents declared invalid, we may:

incur substantial monetary damages;
encounter significant delays in bringing our key products to market; and/or
be precluded from participating in the manufacture, use or sale of our key products or methods of treatment requiring licenses.

Even if we are successful in these proceedings, we may incur substantial costs and divert management time and attention in pursuing these proceedings, which
could have a material adverse effect on us.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them.

Because we rely on third parties to develop our products, we must share trade secrets with them. We seek to protect our proprietary technology in part by entering
into  confidentiality  agreements  and,  if  applicable,  material  transfer  agreements,  collaborative  research  agreements,  consulting  agreements  or  other  similar
agreements  with  our  collaborators,  advisors,  employees  and  consultants  prior  to  beginning  research  or  disclosing  proprietary  information.  These  agreements
typically restrict  the ability of our collaborators,  advisors, employees and consultants to publish data potentially relating to our trade secrets. Our academic and
clinical collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure
our intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively by us, although in some cases we may
share these rights with other parties. We may also conduct joint research and development programs which may require us to share trade secrets under the terms of
research  and  development  collaboration  or  similar  agreements.  Despite  our  efforts  to  protect  our  trade  secrets,  our  competitors  may  discover  our  trade  secrets,
either  through  breach  of  these  agreements,  independent  development  or  publication  of  information  including  our  trade  secrets  in  cases  where  we  do  not  have
proprietary or otherwise protected rights at the time of publication. A competitor's discovery of our trade secrets may impair our competitive position and could
have a material adverse effect on our business and financial condition.

Risks Related to Our Common Shares

Our common share price has been volatile in recent years, and may continue to be volatile.

The  market  prices  for  securities  of  biopharmaceutical  companies,  including  ours,  have  historically  been  volatile.  In  the  year  ended  December  31,  2019,  our
common shares traded on the Nasdaq at a high of $2.13 and a low of $0.24 per share and on the TSX at a high of CDN $2.76 and a low of CDN $0.30 per share. In
the year ended December 31, 2018, our common shares traded on the Nasdaq at a high of $9.16 and a low of $1.46 per share and on the TSX at a high of CDN
$11.44 and a low of CDN $1.99 per share. A number of factors could influence the volatility in the trading price of our common shares, including changes in the
economy or in the financial markets, industry related developments, the results of product development and commercialization, changes in government regulations,
and  developments  concerning  proprietary  rights,  litigation  and  cash  flow.  Our  quarterly  losses  may  vary  because  of  the  timing  of  costs  for  manufacturing,
preclinical studies and clinical trials. Also, the reporting of adverse safety events involving our products and public rumors about such events could cause our share
price to decline or experience periods of volatility. Each of these factors could lead to increased volatility in the market price of our common shares. In addition,
changes in the market prices of the securities of our competitors may also lead to fluctuations in the trading price of our common shares.

Management’s Discussion and Analysis

We have never paid dividends and do not expect to do so in the foreseeable future.

We have not declared or paid any cash dividends on our common or preferred shares to date. The payment of dividends in the future will be dependent on our
earnings and financial condition in addition to such other factors as our board of directors considers appropriate. Unless and until we pay dividends, shareholders
may not receive a return on their shares. There is no present intention by our board of directors to pay dividends on our shares.

Future sales or issuances of equity securities and the conversion of outstanding securities to common shares could decrease the value of the common shares,
dilute  investors'  voting  power,  and  reduce  our  earnings  per  share.  There  are  a  large  number  of  common  shares  underlying  our  outstanding  options  and
warrants and the exercise of these options and/or warrants may depress the market price of our common shares and cause immediate and substantial dilution
to our existing stockholders.

As of December 31, 2019, we had 28,938,831 common shares issued and outstanding, preferred shares convertible into an additional 9,440,788 common shares,
outstanding options to purchase 5,366,645 common shares and outstanding warrants to purchase 18,750,000 common shares. The issuance of common shares upon
exercise of our outstanding options and warrants, or the conversion of our preferred shares, will cause immediate and substantial dilution to our stockholders.

We  may  sell  additional  equity  securities  in  future  offerings,  including  through  the  sale  of  securities  convertible  into  equity  securities,  to  finance  operations,
acquisitions or projects, and issue additional common shares if outstanding warrants or stock options are exercised, or preferred shares are converted to common
shares,  which  may  result  in  dilution.  See  the  information  in  the  section  of  this  MD&A  entitled  "Description  of  Share  Capital"  for  details  of  our  outstanding
securities convertible into common shares. In the February 2019 public offering, we issued warrants with a price protection feature that resets the exercise price of
the warrant under certain conditions including the issuance of common shares, or securities convertible into common shares, at prices below the exercise price of
$0.96.

Our board of directors has the authority to authorize certain offers and sales of additional securities without the vote of, or prior notice to, shareholders. Based on
the need for additional capital to fund expected expenditures and growth, it is likely that we will issue additional securities to provide such capital. Such additional
issuances may involve the issuance of a significant number of common shares at prices less than the current market price for our common shares.

Sales of substantial amounts of our securities, or the availability of such securities for sale, as well as the issuance of substantial amounts of our common shares
upon conversion of outstanding convertible equity securities, could adversely affect the prevailing market prices for our securities and dilute investors' earnings per
share. A decline in the market prices of our securities could impair our ability to raise additional capital through the sale of securities should we desire to do so.

US  holders  of  10%  or  more  of  the  voting  power  of  our  common  shares  may  be  subject  to  US  federal  income  taxation  at  ordinary  income  tax  rates  on
undistributed earnings and profits.

There is a risk that we will be classified as a controlled foreign corporation, or CFC, for US federal income tax purposes. We will generally be classified as a CFC
if  more  than  50%  of  our  outstanding  shares,  measured  by  reference  to  voting  power  or  value,  are  owned  (directly,  indirectly  or  by  attribution)  by  "US
Shareholders."  For this  purpose,  a  "US Shareholder"  is  any  US person  that  owns directly,  indirectly  or  by attribution,  10%  or  more  of  the voting  power  of  our
outstanding shares. If we are classified as a CFC, a US Shareholder may be subject to US income taxation at ordinary income tax rates on all or a portion of our
undistributed earnings and profits attributable to "subpart F income" and may also be subject to tax at ordinary income tax rates on any gain realized on a sale of
common shares, to the extent of our current and accumulated earnings and profits attributable to such shares. The CFC rules are complex and US Shareholders of
our common shares are urged to consult their own tax advisors regarding the possible application of the CFC rules to them in their particular circumstances.

Management’s Discussion and Analysis

We are likely a "passive foreign investment company," which may have adverse US federal income tax consequences for US shareholders.

US investors should be aware that we believe we were classified as a PFIC during the tax years ended 
December 31, 2019 and 2018, and based on current business plans and financial expectations, we believe that we may be a PFIC for the current tax year and may
be a PFIC in future tax years. If we are a PFIC for any year during a US shareholder's holding period of our common shares or Series II First Preferred Shares, then
such US shareholder generally will be required to treat any gain realized upon a disposition of our common shares or Series II First Preferred Shares, or any so-
called "excess distribution" received on our common shares or Series II First Preferred Shares, as ordinary income, and to pay an interest charge on a portion of
such gain or distributions, unless the shareholder makes a timely and effective "qualified electing fund" election, or QEF Election, or a "mark-to-market" election
with respect to our common shares or Series II First Preferred Shares. A US shareholder who makes a QEF Election generally must report on a current basis its
share of our net capital gain and ordinary earnings for any year in which we are a PFIC, which may or may not be readily available, whether or not we distribute
any amounts to our shareholders. A US shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the
fair market value of the common shares over the shareholder's adjusted tax basis therein. A mark-to-market election is not expected to be available with respect to
our Series II First Preferred Shares. Each US shareholder should consult its own tax advisors regarding the PFIC rules and the US federal income tax consequences
of the acquisition, ownership and disposition of our common shares or Series II First Preferred Shares.

The effect of comprehensive US tax reform legislation on the Company is uncertain.

On December 22, 2017, the US government enacted H.R. 1, "An Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the
budget for fiscal year 2018" (informally titled the "Tax Cuts and Jobs Act"). Among a number of significant changes to the US federal income tax rules, the Tax
Cuts  and  Jobs  Act  reduces  the  marginal  US  corporate  income  tax  rate  from  35%  to  21%,  limits  the  deduction  for  net  interest  expense,  shifts  the  United  States
toward a more territorial tax system, and imposes new taxes to combat erosion of the US federal income tax base, such as a one-time tax on earnings of certain
foreign  subsidiaries  that  were previously  tax  deferred  and  a  new minimum  tax  on foreign  earnings.  The  effects  of  the  Tax  Cuts and  Jobs Act  on our  company,
whether  adverse  or  favorable,  are  uncertain,  and  may  not  become  evident  for  some  period  of  time,  but  could  have  a  material  adverse  effect  on  our  business,
financial position or results from operations.

It may be difficult for non-Canadian investors to obtain and enforce judgments against us because of our Canadian incorporation and presence.

We are a corporation  existing  under  the laws of the Province  of British  Columbia,  Canada. Several  of our directors  and officers,  and several  of the experts  are
residents  of  Canada,  and  all  or  a  substantial  portion  of  their  assets,  and  a  substantial  portion  of  our  assets,  are  located  outside  the  United  States.  Consequently,
although we have appointed an agent for service of process in the United States, it may be difficult for holders of our securities who reside in the United States to
effect service within the United States upon those directors and officers, and the experts who are not residents of the United States. It may also be difficult for
holders of our securities who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil
liability and the civil liability of our directors, officers and experts under the United States federal securities laws. Investors should not assume that Canadian courts
(i) would enforce judgments of United States courts obtained in actions against us or such directors, officers or experts predicated upon the civil liability provisions
of the United States federal securities laws or the securities or "blue sky" laws of any state or jurisdiction of the United States or (ii) would enforce, in original
actions, liabilities against us or such directors, officers or experts predicated upon the United States federal securities laws or any securities or "blue sky" laws of
any state or jurisdiction of the United States. In addition, the protections afforded by Canadian securities laws may not be available to investors in the United States.

Management’s Discussion and Analysis

We are an "emerging growth company," and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make
our common shares less attractive to investors.

We are an "emerging growth company," as defined in the JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of
exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  emerging  growth  companies,  including  not  being
required  to  comply  with  the  auditor  attestation  requirements  of  Section  404  of  the  Sarbanes-Oxley  Act,  reduced  disclosure  obligations  regarding  executive
compensation  in our periodic  reports  and exemptions  from the requirements  of holding a nonbinding advisory vote on executive  compensation  and shareholder
approval of any golden parachute payments not previously approved. We could be an emerging growth company until the last day of our fiscal year following the
fifth anniversary of the date of the first sale of our common shares pursuant to an effective registration statement under the US Securities Act of 1933, which is
December 31, 2020, although circumstances could cause us to lose that status earlier. We cannot predict if investors will find our common shares less attractive
because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our
common shares and our share price may be more volatile.

We expect to lose our foreign private issuer status which will require us to comply with the US domestic reporting regime under the Exchange Act and result in
significant additional compliance activity and increased costs and expenses.

We are currently a "foreign private issuer," as such term is defined in Rule 405 under the Securities Act, and, therefore, we are not required to comply with all the
periodic  disclosure  and  current  reporting  requirements  of  the  Exchange  Act  and  related  rules  and  regulations.  As  a  result,  there  may  currently  be  less  publicly
available information about us than if we were a United States domestic issuer. For example, currently we are not subject to the proxy rules in the United States and
disclosure with respect to our annual meetings is currently governed by Canadian requirements. Under Rule 405, the determination of foreign private issuer status
is made annually on the last business day of an issuer's most recently completed second fiscal quarter and, accordingly, the next determination will be made with
respect  to  us  on  June  30,  2020.  We  expect  to  lose  our  foreign  private  issuer  status  on  the  next  determination  date  since  (i)  we  believe  at  least  50%  of  our
outstanding common shares were held by US residents and (ii) the majority of our directors are US citizens, which we do not expect to change before the next
determination date.  As a result, we expect to be required to comply with US domestic issuer requirements beginning January 1, 2021.

The regulatory and compliance costs to us under US securities laws as a US domestic issuer may be significantly more than costs we incur as a foreign private
issuer. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on US domestic issuer forms with the SEC,
which  are  more  detailed  and  extensive  in  certain  respects  than  the  forms  available  to  a  foreign  private  issuer.  We  will  be  required  under  current  SEC  rules  to
prepare our consolidated financial statements in accordance with US generally accepted accounting principles ("US GAAP") and modify certain of our policies to
comply  with  corporate  governance  practices  associated  with  US  domestic  issuers.    In  addition,  we  may  lose  our  ability  to  rely  upon  exemptions  from  certain
corporate governance requirements on US stock exchanges that are available to foreign private issuers, and exemptions from requirements related to the preparation
and solicitation of proxies (including compliance with full disclosure obligations regarding executive compensation in proxy statements and the requirements of
holding a nonbinding advisory vote on certain  executive  compensation  matters,  such as "say on pay" and "say on frequency").  Moreover, we will no longer be
exempt from certain of the provisions of US securities laws, such as Regulation FD (which restricts the selective disclosure of material information), exemptions
for filing beneficial ownership reports under Section 16(a) for officers, directors and 10% shareholders and the Section 16(b) short swing profit rules. In light of our
expectations, we have already started to prepare for the consequences of becoming a US domestic issuer, including those described above, and we expect that the
loss of foreign private issuer status will increase our legal and financial compliance costs and will make some activities highly time-consuming and costly. The
additional costs could have an adverse impact on our results of operations, financial position and cash flows.

In addition, the transition to being treated as a US domestic issuer may make it more difficult and expensive for us to obtain director and officer liability insurance,
and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage.

Management’s Discussion and Analysis

Any failure to maintain an effective system of internal controls may result in material misstatements of our consolidated financial statements or cause us to fail
to meet our reporting obligations or fail to prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting, which would
harm our business and could negatively impact the price of our common shares.

Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud. If we fail to maintain an effective system of internal controls,
we might not be able to report our financial results accurately or prevent fraud; and in that case, our shareholders could lose confidence in our financial reporting,
which  would  harm  our  business  and  could  negatively  impact  the  price  of  our  common  shares.  While  we  believe  that  we  have  sufficient  personnel  and  review
procedures to allow us to maintain an effective system of internal controls, we cannot provide assurance that we will not experience potential material weaknesses
in our internal control. Even if we conclude that our internal control over financial reporting provides reasonable assurance regarding the reliability of financial
reporting and the preparation of consolidated financial statements for external purposes in accordance with IFRS as issued by the IASB, because of its inherent
limitations, internal control over financial reporting may not prevent or detect fraud or misstatements. Failure to implement required new or improved controls, or
difficulties encountered in their implementation, could harm our results of operations or cause us to fail to meet our future reporting obligations.

If we fail to timely achieve and maintain the adequacy of our internal control over financial reporting, we may not be able to produce reliable financial reports or
help  prevent  fraud.  Our  failure  to  achieve  and  maintain  effective  internal  control  over  financial  reporting  could  prevent  us  from  complying  with  our  reporting
obligations on a timely basis, which could result in the loss of investor confidence in the reliability of our consolidated financial statements, harm our business and
negatively impact the trading price of our common shares.

Our charter documents and certain Canadian legislation could delay or deter a change of control, limit attempts by our shareholders to replace or remove our
current management and limit the market price of our common shares.

Our authorized preferred shares are available for issuance from time to time at the discretion of our board of directors, without shareholder approval. Our articles
grant our board of directors the authority to determine the special rights and restrictions granted to or imposed on any unissued series of preferred shares, and those
rights may be superior to those of our common shares. Further, the Investment Canada Act subjects any acquisition of control of a company by a non-Canadian to
government  review  if  the  value  of  the  assets  as  calculated  pursuant  to  the  legislation  exceeds  a  threshold  amount  or  in  other  circumstances  determined  at  the
discretion of the Canadian government. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to be of net
benefit  to  Canada  and  the  Canadian  government  is  satisfied  that  no  other  important  concerns  arise  from  the  acquisition  of  control.  Any  of  the  foregoing  could
prevent or delay a change of control and may deprive or limit strategic opportunities to our shareholders to sell their shares.

DISCLOSURE CONTROLS AND INTERNAL CONTROLS OVER FINANCIAL REPORTING

We have implemented a system of internal controls that we believe adequately protects our assets and is appropriate for the nature of our business and the size of
our operations. Our internal control system was designed to provide reasonable assurance that all transactions are accurately recorded, that transactions are recorded
as necessary to permit preparation of financial statements in accordance with IFRS, and that our assets are safeguarded.

These  internal  controls  include  disclosure  controls  and  procedures  designed  to  ensure  that  information  required  to  be  disclosed  by  us  is  accumulated  and
communicated as appropriate to allow timely decisions regarding required disclosure.

Internal control over financial reporting means a process designed by or under the supervision of the Chief Executive Officer and the Chief Financial Officer to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
IFRS as issued by the IASB. The internal controls are not expected to prevent and detect all misstatements due to error or fraud.

There  were  no  changes  in  our  internal  control  over  financial  reporting  that  occurred  during  the  three  months  ended  December  31,  2019  that  have  materially
affected, or are reasonably likely to materially affect, our internal control over financial reporting. As at December 31, 2019, we have assessed the effectiveness of
our  internal  control  over  financial  reporting  and  disclosure  controls  and  procedures  using  the  Committee  of  Sponsoring  Organizations  of  the  Treadway
Commission's  2013  framework.  Based  on  their  evaluation,  the  Chief  Executive  Officer  and  the  Chief  Financial  Officer  have  concluded  that  these  controls  and
procedures are effective.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Directors of Trillium Therapeutics Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statements of financial position of Trillium Therapeutics Inc. (the Company) as of December 31, 2019 and 2018,
the related consolidated statements of loss and comprehensive loss, changes in equity and cash flows for each of the years in the two-year period ended December
31, 2019, 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, 2019 and 2018, and the results of its operations and its cash flows for each of
the years in the two- year period ended December 31, 2019, in conformity with International Financial Reporting Standards (IFRSs) as issued by the International
Accounting Standards Board.

Changes in Accounting Policies

As discussed in Note 2(c) to the consolidated financial statements, the Company changed its presentation currency from Canadian dollars to United States dollars
and included the disclosure of the January 1, 2018 consolidated statement of financial position.

As discussed in Note 3(m) to the consolidated financial statements, the Company changed its method of accounting for leases in 2019 due to the adoption of IFRS
16, Leases.

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company's  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United
States) (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 consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to
have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of
internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company's  internal  control  over  financial
reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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
consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company's auditor since 2004.

Notes to the Consolidated Financial Statements 
For the years ended December 31, 2019 and 2018 

Amounts in thousands of US dollars, except per share amounts and where noted

 1.  Corporate information

Trillium Therapeutics Inc. (the “Company” or “Trillium”) is a clinical-stage immuno-oncology company developing innovative therapies for the treatment of
cancer.  The  Company  is  a  corporation  existing  under  the  laws  of  the  Province  of  British  Columbia.  The  Company’s  head  office  is  located  at  2488  Dunwin
Drive, Mississauga, Ontario, L5L 1J9, and it is listed on the Toronto Stock Exchange and on the Nasdaq Stock Market.

2.  Basis of presentation

(a) Statement of compliance

The  consolidated  financial  statements  have  been  prepared  in  accordance  with  International  Financial  Reporting  Standards  (“IFRS”)  as  issued  by  the
International Accounting Standards Board (“IASB”).

These consolidated financial statements were approved by the Company’s board of directors on March 5, 2020.

(b) Basis of measurement

These consolidated financial statements have been prepared on the historical cost basis, unless otherwise noted.

(c) Functional and presentation currency

The  Company’s  functional  currency  is  Canadian  dollars.  In  the  last  quarter  of  2019,  the  Company  elected  to  change  its  presentation  currency  to  the  United
States dollar. Comparative financial information previously expressed in Canadian dollars is now presented in United States dollars for all periods shown, using
the  exchange  rate  applicable  at  the  reporting  date  for  assets  and  liabilities,  and  the  average  exchange  rate  of  the  corresponding  periods  for  the  consolidated
statements of loss and cash flow items. Equity transactions have been translated at historical rates since inception. The net adjustment arising from the effect of
the change in presentation currency has been recognized in accumulated other comprehensive loss.

(d) Use of significant estimates and assumptions

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application
of accounting policies and the reported amounts of assets and liabilities, revenue and expenses, related disclosures of contingent assets and liabilities. Actual
results  could  differ  materially  from  these  estimates  and  assumptions.  The  Company  reviews  its  estimates  and  underlying  assumptions  on  an  ongoing  basis.
Revisions are recognized in the period in which the estimates are revised and may impact future periods.

Management has applied significant estimates and assumptions to the following:

Going concern

In  the  preparation  of  financial  statements,  management  is  required  to  identify  when  events  or  conditions  indicate  that  significant  doubt  may  exist  about  the
Company’s ability to continue as a going concern. Significant doubt about the Company’s ability to continue as a going concern would exist when relevant
conditions and events, considered in the aggregate, indicate that the Company will not be able to meet its obligations as they become due for a period of at least,
but not limited to, twelve months from the balance sheet date. When the Company identifies conditions or events that raise potential for significant doubt about
its ability to continue as a going concern, the Company considers whether its plans that are intended to mitigate those relevant conditions or events will alleviate
the potential significant doubt.

The  Company  will  require  ongoing  financing  in  order  to  continue  research  and  development  activities,  as  it  has  not  earned  significant  revenue  or  reached
successful  commercialization  of  its  products.  After  considering  its  plans  to  mitigate  the  going  concern  risk,  management  has  concluded  that  there  are  no
material uncertainties related to events or conditions that may cast significant doubt upon the Company’s ability to continue as a going concern for a period of
twelve months from the balance sheet date.

For the years ended December 31, 2019 and 2018

 2.  Basis of presentation (continued)

Impairment of long-lived assets

Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances indicating that the carrying value of the asset may not
be recoverable. For the purpose of measuring recoverable amounts, assets are grouped at the lowest levels for which there are separately identifiable cash flows
(cash-generating units). The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use (being the present value of the expected
future cash flows of the relevant asset or cash-generating unit). An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds
its recoverable amount. Management evaluates impairment losses for potential reversals when events or circumstances warrant such consideration.

Valuation of share-based compensation and warrants

Management  measures  the  costs  for  share-based  compensation  and  warrants  using  market-based  option  valuation  techniques.  Assumptions  are  made  and
estimates are used in applying the valuation techniques. These include estimating the future volatility of the share price, expected dividend yield, expected risk-
free  interest  rate,  future  employee  turnover  rates,  future  exercise  behaviours  and  corporate  performance.  Such  estimates  and  assumptions  are  inherently
uncertain. Changes in these assumptions affect the fair value estimates of share-based compensation and warrants.

The  fair  value  of  the  warrant  liability  was  calculated  using  a  Black-Scholes  fair  value  model  and  was  then  recorded  at  its  relative  fair  value  following  an
approach to allocate  proceeds  to the warrant liability  and shares. The difference  between the Black- Scholes warrant value and the relative  fair value of the
warrants represents a discount on issuance that is being amortized over the five-year life of the warrants.

Functional currency

Management considers the determination of the functional currency of the Company a significant judgment. Management has used its judgment to determine
the functional currency that most faithfully represents the economic effects of the underlying transactions, events and conditions and considered various factors
including the currency of historical and future expenditures and the currency in which funds from financing activities are generated. A Company’s functional
currency is only changed when there is a material change in the underlying transactions, events and conditions.

3.  Significant accounting policies

The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements.

(a) Basis of consolidation

These consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Trillium Therapeutics USA Inc. Subsidiaries are
fully consolidated from the date at which control is determined to have occurred and are deconsolidated from the date that the Company no longer controls the
entity.  The  financial  statements  of  the  subsidiaries  are  prepared  for  the  same  reporting  period  as  the  Company  using  consistent  accounting  policies.
Intercompany transactions, balances and gains and losses on transactions between subsidiaries are eliminated.

(b) Foreign currency

Transactions  in  foreign  currencies  are  translated  to  the  functional  currency  at  the  rate  on  the  date  of  the  transactions.  Monetary  assets  and  liabilities
denominated in foreign currencies are retranslated at the spot rate of exchange as at the reporting date. All differences are taken to profit or loss. Non-monetary
items that  are measured  in terms  of historical  cost  in a foreign  currency  are translated  using the exchange rate  as at the date of the initial  transaction.  Non-
monetary items measured at fair value in a foreign currency are translated using the exchange rate at the date when the fair value was determined.

(c) Cash and cash equivalents, and marketable securities

Cash and cash equivalents
Cash equivalents include guaranteed investment certificates (as at December 31, 2019 and 2018 of $7,000 and $nil, respectively) with a maturity of 90 days or
less. The Company has classified its cash and cash equivalents as amortized cost.

Marketable securities
Marketable securities consist of guaranteed investment certificates with a maturity of greater than 90 days and less than one year. The Company has classified
its marketable securities as amortized cost.

(d) Property and equipment

Recognition and measurement

Items of property and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. Cost includes the expenditure that is
directly  attributable  to  the  acquisition  of  the  asset.  When  parts  of  an  item  of  property  and  equipment  have  different  useful  lives,  they  are  accounted  for  as
separate items of property and equipment. Gains and losses on disposal of an item of property and equipment are determined by comparing the proceeds from
disposal with the carrying amount of property and equipment, and are recognized in profit or loss.

Depreciation

The estimated useful lives and the methods of depreciation are as follows:

Asset
Lab equipment
Computer equipment
Office equipment
Leaseholds
Leased buildings

Basis
20% declining balance
30% declining balance
20% declining balance
Straight-line over expected lease term
Straight-line over expected lease term

Estimates for depreciation methods, useful lives and residual values are reviewed at each reporting period-end and adjusted if appropriate. Depreciation expense
is recognized in research and development expenses.

(e) Intangible assets

Research and development

Expenditures on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, are recognized in profit
or loss as incurred.

Development  activities  involve  a plan  or  design for  the  production  of  new or  substantially  improved  products  and processes.  Development  expenditures  are
capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are
probable,  and  the  Company  intends  to  complete  development  and  has  sufficient  resources  to  complete  development  and  to  use  or  sell  the  asset.  Other
development expenditures are expensed as incurred. No internal development costs have been capitalized to date.

Research  and  development  expenses  include  all  direct  and  indirect  operating  expenses  supporting  the  products  in  development.  The  costs  incurred  in
establishing and maintaining patents are expensed as incurred.

3.   Significant accounting policies (continued)

Intangible assets

Intangible assets that consist of intellectual property acquired separately, have finite useful lives, and are measured at cost less accumulated amortization and
accumulated impairment losses. Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to
which they relate. All other expenditures are recognized in profit or loss as incurred.

Amortization is recognized in profit or loss on a straight-line basis over the estimated useful lives of intangible assets from the date they are available for use in
the manner intended by management.

The amortization method and amortization period of an intangible asset with a finite life is reviewed at least annually. Changes in the expected useful life or the
expected  pattern  of  consumption  of  future  economic  benefits  embodied  in  the  asset  are  accounted  for  by  changing  the  amortization  period  or  method,  as
appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in research and
development expenses.

(f)  Impairment of non-financial assets

The carrying amounts of the Company's non-financial assets are reviewed at each reporting date to determine whether there is any indication of impairment. If
such an indication exists, the recoverable amount is estimated. The recoverable amount of an asset or a cash-generating unit is the greater of its value in use and
its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that
reflects current market assessments of the time value of money and the risks specific to the asset or cash-generating unit. For the purpose of impairment testing,
assets that cannot be tested individually are grouped together into the smallest group of assets that generate cash inflows from continuing use that are largely
independent of cash inflows of other assets or cash-generating units. An impairment loss is recognized if the carrying amount of an asset or its related cash-
generating unit exceeds its estimated recoverable amount. Impairment losses for intangible assets are recognized in research and development expenses.

Impairment  losses  recognized  in  prior  periods  are  assessed  at  each  reporting  date  for  any  indications  that  the  loss  has  decreased  or  no  longer  exists.  An
impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the
extent  that  the  asset's  carrying  amount  does  not  exceed  the  carrying  amount  that  would  have  been  determined,  net  of  depreciation  or  amortization,  if  no
impairment loss had been recognized.

(g) Provisions

A provision  is  recognized  if,  as  a  result  of  a  past  event,  the  Company  has  a  present  legal  or  constructive  obligation  that  can  be  estimated  reliably,  and  it  is
probable that an outflow of economic benefits will be required to settle the obligation. Provisions are assessed by discounting the expected future cash flows at
a  pre-tax  rate  that  reflects  current  market  assessments  of  the  time  value  of  money  and  the  risks  specific  to  the  liability.  The  unwinding  of  the  discount  on
provisions is recognized in finance costs.

A  provision  for  onerous  contracts  is  recognized  when  the  unavoidable  costs  of  meeting  the  obligations  under  the  contract  exceed  the  economic  benefits
expected to be received under it. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected
net cost of continuing with the contract.

(h) Revenue recognition

The Company recognizes revenue at the inception of a license or option agreement when there are no future performance obligations. With the application of
the sales-based royalties exception, sales-based royalties contingent on sales-based thresholds are recognized when the subsequent sales occur.

(i) Government assistance

Government assistance relating to research and development is recorded as a reduction of expenses when the related expenditures are incurred.

3.   Significant accounting policies (continued)

(j)  Share-based compensation

The grant-date fair value of share-based payment awards granted to employees is recognized as personnel costs, with a corresponding increase in contributed
surplus,  over  the  period  that  the  employees  unconditionally  become  entitled  to  the  awards.  The  amount  recognized  as  an  expense  is  adjusted  to  reflect  the
number of awards for which the related service and non-market vesting conditions are expected to be met, such that the amount ultimately recognized as an
expense is based on the number of awards that met the related service and non-market performance conditions at the vesting date.

For  equity-settled  share-based  payment  transactions,  the  Company  measures  the  goods  or  services  received,  and  the  corresponding  increase  in  contributed
surplus, at the fair value of the goods or services received, unless that fair value cannot be estimated reliably. If the Company cannot estimate reliably the fair
value  of  the  goods  or  services  received,  it  measures  their  value  by  reference  to  the  fair  value  of  the  equity  instruments  granted.  Transactions  measured  by
reference to the fair value of the equity instruments granted have their fair values remeasured at each vesting and reporting date until fully vested.

(k) Income taxes

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the
amounts used for taxation purposes. Deferred tax is not recognized for temporary differences on the initial recognition of assets or liabilities in a transaction
that is not a business combination and that affects neither accounting nor taxable income or loss.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax assets and liabilities, and they relate to income taxes levied
by the same tax authority on the same taxable entity.

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted
or substantively enacted at the reporting date. A deferred tax asset is recognized for unused tax losses, tax credits and deductible temporary differences, to the
extent that it is probable that future taxable profits will be available against which they can be utilized.

Investment tax credits earned from scientific research and development expenditures are recorded when collectability is reasonably assured.

(l)  Loss per share

Basic loss per share is computed by dividing the net loss available to common shareholders by the weighted average number of shares outstanding during the
reporting period. Diluted loss per share is computed similar to basic loss per share except that the weighted average number of shares outstanding is increased
to include additional shares for the assumed exercise of stock options, warrants, and conversion of preferred shares, if dilutive. The number of additional shares
is calculated by assuming that outstanding preferred shares would convert to common shares and that outstanding stock options and warrants were exercised
and  the  proceeds  from  such  exercises  were  used  to  acquire  common  stock  at  the  average  market  price  during  the  reporting  period.  The  inclusion  of  the
Company's stock options, warrants and preferred shares in the computation of diluted loss per share has an antidilutive effect on the loss per share and has
therefore been excluded from the calculation of diluted loss per share.

(m) New standards, amendments and interpretations adopted during 2019

IFRS 16 Leases

IFRS 16 Leases (“IFRS 16”) sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for
all  leases  under  a  single  on-balance  sheet  model,  with  certain  exemptions.  The  standard  includes  two  recognition  exemptions  for  lessees  –  leases  of  “low-
value” assets and short-term leases with a lease term of 12 months or less. At the commencement date of a lease, a lessee will recognize a liability to make
lease payments and an asset representing the right to use the underlying asset during the lease term. Lessees will be required to separately recognize the interest
expense  on  the  lease  liability  and  the  depreciation  expense  on  the  right-of-use  asset.  Lessees  are  also  required  to  remeasure  the  lease  liability  upon  the
occurrence of certain events such as a change in lease term. The lessee will generally recognize the amount of the remeasurement of the lease liability as an
adjustment to the right-of-use asset. The new standard was effective for annual periods beginning on or after January 1, 2019.

3.  Significant accounting policies (continued)

The  Company  adopted  IFRS  16  using  the  modified  retrospective  transition  approach,  and  elected  to  use  the  exemptions  proposed  by  the  standard  on  lease
contracts for which the lease term ends within 12 months as of the lease commencement date and on lease contracts where the underlying asset is of low value.
The Company has leases of certain office equipment (i.e. photocopying machines) that are considered of low value.

The effect of adoption of IFRS 16 as at January 1, 2019 (increase/(decrease)) was as follows:

The  Company  recognized  a  right-of-use  asset  based  on  the  amount  equal  to  the  lease  liability,  adjusted  for  any  related  prepaid  and  accrued  lease  payments
previously recognized. The lease liability was recognized based on the present value of remaining lease payments, discounted using the incremental borrowing
rate at the date of initial application. The lease payments include fixed payments less any lease incentives receivable, variable lease payments that depend on an
index  or  rate,  and  amounts  expected  to  be  paid  under  residual  value  guarantees.  The  variable  lease  payments  that  do  not  depend  on  an  index  or  a  rate  are
recognized as expense in the period as incurred.

The Company also applied the following available practical expedients:

• 
Excluded the initial direct costs from the measurement of the right-of-use asset at the date of initial application;
•  Used hindsight in determining the lease term where the contract contains options to extend or terminate the lease; and
•

Elected  not  to  separate  non-lease  components  from  lease  components,  and  instead  accounted  for  each  lease  component  and  any  associated  non-lease
components as a single lease component.

In  addition  to  the  Mississauga  facility  lease  that  was  transitioned  as  at  January  1,  2019,  an  office  lease  for  operations  in  Cambridge,  Massachusetts  was
recognized  under  IFRS  16  during  the  year  ended  December  31,  2019.  This  lease  resulted  in  the  recognition  of  a  right-of-use  asset  and  corresponding  lease
liability of $599.

The carrying amounts of the Company’s right-of-use assets and lease liabilities and movements during 2019 were as follows:

of Fluorinov. On May 13, 2019, Trillium and former Fluorinov shareholders amended the Fluorinov purchase agreements to remove the existing milestone and
royalty payments in favour of a revenue sharing arrangement. On the deletion of the milestones from the agreements, the contingent consideration was reduced
to $nil.

9.  Share capital

(a) Authorized

The  authorized  share  capital  of  the  Company  consists  of  an  unlimited  number  of  common  shares,  Class  B  shares  and  First  Preferred  Shares,  in  each  case
without nominal or par value. Common shares are voting and may receive dividends as declared at the discretion of the board of directors. Class B shares are
non-voting and convertible to common shares at the holder’s discretion, on a one-for-one basis. Upon dissolution or wind-up of the Company, Class B shares
participate rateably with the common shares in the distribution of the Company’s assets. First Preferred Shares have voting rights as decided upon by the board
of directors at the time of grant. Upon dissolution or wind-up of the Company, First Preferred Shares are entitled to priority over common and Class B shares.

The  Company  has  Series  I  First  Preferred  Shares  that  are  non-voting,  may  receive  dividends  as  declared  at  the  discretion  of  the  board  of  directors,  and  are
convertible to common shares at the holder’s discretion, on the basis of 30 Series I First Preferred Shares for one common share.

The Company has Series II First Preferred  Shares that are non-voting, may receive  dividends as declared  at the discretion  of the board of directors, and are
convertible to common shares at the holder’s discretion, on the basis of one Series II First Preferred Share for one common share.

Holders may not convert Series I or Series II First Preferred Shares into common shares if, after giving effect to the exercise of conversion, the holder would
have beneficial ownership or direction or control over common shares in excess of 4.99% of the then outstanding common shares. This limit may be raised at
the option of the holder on 61 days’ prior written notice: (i) up to 9.99%, (ii) up to 19.99%, subject to clearance of a personal information form submitted by the
holder to the Toronto Stock Exchange; and (iii) above 19.99%, subject to approval by the Toronto Stock Exchange and shareholder approval.

(b) Share capital issued – year ended December 31, 2019

In February 2019, the Company completed an underwritten public offering of 6,550,000 common share units and 12,200,000 Series II Non-Voting Convertible
First Preferred Share units, each issued at $0.80 per unit. The gross proceeds from this offering were $15,000, before deducting offering expenses of $1,117.
Each common share unit comprises one common share of the Company and one common share purchase warrant. Each common share purchase warrant will be
exercisable for one common share at a price of $0.96 per common share purchase warrant for 60 months. Each preferred share unit comprises one Series II First
Preferred  Share  and  one  Series  II  First  Preferred  Share  purchase  warrant.  Each  Series  II  First  Preferred  Share  purchase  warrant  will  be  exercisable  for  one
Series  II  First  Preferred  Share  at  a  price  of  $0.96  per  Series  II  First  Preferred  Share  purchase  warrant  for  60  months.  Each  purchase  warrant  has  a  price
protection feature that resets the exercise price of the warrant under certain conditions including the issuance of common shares, or securities convertible into
common shares, at prices below the exercise price. In addition, in the event of a “Fundamental Transaction” (as defined in the related warrant agreement, which
generally  includes  any  merger  with  another  entity,  the  sale,  transfer  or  other  disposition  of  all  or  substantially  all  of  our  assets  to  another  entity,  or  the
acquisition  by  a  person  of  more  than  50%  of  our  common  stock),  each  warrant  holder  will  have  the  right  up  to  90  days  after  the  consummation  of  the
Fundamental Transaction to require us to repurchase the warrant for a purchase price in cash equal to the Black Scholes value (as calculated under the warrant
agreement) of the then remaining unexercised portion of such warrant on the date of such Fundamental Transaction.

Proceeds  were  allocated  amongst  common  shares,  preferred  shares  and  warrants  by  applying  a  relative  fair  value  approach,  with  fair  value  of  the  warrants
determined using the Black-Scholes model, resulting in an initial warrant liability of $5,372. The difference between the allocated amount of the warrants and
their  fair  value  was  a  discount  of  $2,514,  which  is  being  amortized  on  a  straight-line  basis  over  the  five-year  term  of  the  warrants.  Purchase  warrants  are
recognized as liabilities, as the price protection feature creates potential variability in the price at which the warrants will be settled as well as the warrants being
issued in U.S. dollars, which differs from the Company’s functional currency. Warrants are revalued each period-end at fair value through profit and loss. The
change in fair value of the warrant liability for the year ended December 31, 2019 was an increase of $4,967.

The  warrant  liability  was  determined  based  on  the  fair  value  of  warrants  at  the  issue  date  and  the  reporting  date  using  the  Black-Scholes  model  with  the
following assumptions:

Expected warrant life
Risk-free interest rate
Dividend yield
Expected volatility

Issue date
February 28, 2019
5.0 years
1.8%
0%
86.9%

Reporting date
December 31, 2019
4.2 years
1.5%
0%
96.8%

The risk-free interest rate is based on the implied yield on a Government of Canada zero-coupon issue with a remaining term equal to the expected term of the
warrants. The expected volatility is based on the historical volatility for the Company.

During the year ended December 31, 2019, 7,700,000 Series II First Preferred Shares were converted into 7,700,000 common shares.

Share capital issued – year ended December 31, 2018

In  a  June  2018  amendment  to  the  license  agreement  for  SIRPαFc,  the  sublicense  revenue  sharing  provisions  were  removed  in  return  for  a  payment  to  the
licensors of $2,290 in the form of 369,621 common shares, which was recorded in research and development expenses.

During the year ended December 31, 2018, 35,154,286 Series I First Preferred Shares were converted into 1,171,806 common shares.

(c) Weighted average number of common shares

The weighted average number of common shares outstanding for the years ended December 31, 2019 and 2018 were 25,264,447 and 13,906,074, respectively.
The Company has not adjusted its weighted average number of common shares outstanding in the calculation of diluted loss per share, as any adjustment would
be antidilutive.

(d) Warrants

There were 69,073,031 common share warrants with a weighted average exercise price of $0.28 that were exercisable at a ratio of 30:1 into common shares that
expired in 2018.

There were 1,190,476 Preferred Warrants that were exercisable at $7.93 per warrant for one common share or one Series II First Preferred Share that expired in
December 2018.

(e) Stock option plan

The 2018 Stock Option Plan was approved by the Company’s shareholders at the annual meeting held on June 1, 2018. Stock options granted are equity-settled,
have a vesting period of between 18 months and 4 years and have a maximum term of 10 years. The total number of common shares available for issuance
under the Company’s 2018 Stock Option Plan is 3,894,501. As at December 31, 2019, the Company was entitled to issue an additional 327,856 stock options
under the 2018 Stock Option Plan.

During the year ended December 31, 2019, 200,213 unvested stock options were forfeited resulting in a reversal of share-based compensation expense of $851.
In addition, 340,000 unvested stock options were modified to be fully vested resulting in the recognition of $603 of share-based compensation expense in the
period but no additional incremental fair value.

In September 2019, the Company introduced an Inducement Stock Option Plan for new executive hires. Stock options granted are equity-settled, have a vesting
period of 4 years and have a maximum term of 10 years. The total number of common shares available for issuance under the Inducement Stock Option Plan is
3,000,000. As at December 31, 2019, the Company was entitled to issue an additional 1,200,000 stock options under the Inducement Stock Option Plan.

Share-based compensation expense was determined based on the fair value of the options at the date of measurement using the Black-Scholes option pricing
model with the weighted average assumptions for the years ended December 31 as follows:

Expected option life
Risk-free interest rate
Dividend yield
Expected volatility

2019
6 years
1.4%
0%
89%

2018
6 years
2.4%
0%
82%

The  Black-Scholes  option  pricing  model  was  developed  to  estimate  the  fair  value  of  freely  tradable,  fully  transferable  options  without  vesting  restrictions,
which  significantly  differs  from  the  Company's  stock  option  awards.  This  model  also  requires  highly  subjective  assumptions,  including  future  stock  price
volatility and average option life, which significantly affect the calculated values.

9.  Share capital (continued)

The risk-free interest rate is based on the implied yield on a Government of Canada zero-coupon issue with a remaining term equal to the expected term of the
option. The expected volatility is based on the historical volatility for the Company. The life of the options is estimated considering the vesting period at the
grant date, the life of the option and the average length of time similar grants have remained outstanding in the past. The forfeiture rate is an estimate based on
historical evidence and future expectations. The dividend yield was excluded from the calculation since it is the present policy of the Company to retain all
earnings to finance operations and future growth.

For the years ended December 31, 2019 and 2018, the Company issued 3,575,600 and 1,082,600 stock options with a fair value of $1,043 and $2,905 and a
weighted average grant date fair value of $0.29 and $2.68, respectively.

During  the  year  ended  December  31,  2019,  340,000  unvested  stock  options  were  modified  to  be  fully  vested.  The  modification  resulted  in  the  accelerated
recognition of $603 of share-based compensation expense.

(f)  Deferred Share Unit Plan

The board of directors approved a Cash-Settled Deferred Share Unit (“DSU”) Plan on November 9, 2016. For the years ended December 31, 2019 and 2018,
there were 2,739,587 and 189,393 DSUs issued, respectively. The fair values of DSUs under this plan as at December 31, 2019 and 2018 were $2,731 and $623,
respectively. For the years ended December 31, 2019 and 2018, the DSU expense, comprised of directors fees paid and the revaluation of the DSU liability, was
an expense of $2,076 and an expense recovery of $207, respectively. The number of DSUs outstanding as at December 31, 2019 and 2018 were 3,045,821 and
334,982, respectively. During 2019, 28,748 DSUs were redeemed in the amount of $10.

10. Revenue

In July 2019, the Company entered into a right-to-use license agreement for one of its small molecule compounds, with initial license fees of $99. Sales-based
royalties, anniversary payments, and milestone payments will be recognized when incurred in future periods.

For the year ended December 31, 2019, the Company recognized licensing revenues of $124 (2018 – $nil).

11. Income taxes

Income taxes recoverable have not been recognized in the consolidated statements of loss and comprehensive loss, as the Company has been incurring losses
since inception, and it is not probable that future taxable profits will be available against which the accumulated tax losses can be utilized.

(a) Unrecognized deferred tax assets

As at December 31, 2019 and 2018, deferred tax assets have not been recognized with respect to the following items:

Non-capital losses carried forward
Tax credits carried forward
Accounting basis of property and equipment and intangible assets in excess of tax basis
Scientific research and experimental development expenditures

(b) As at December 31, 2019 and 2018, the Company had available research and development expenditures of approximately $34,927 and $30,049, respectively,
for income tax purposes, which may be carried forward indefinitely to reduce future years’ taxable income. As at December 31, 2019 and 2018, the Company
also  had  unclaimed  Canadian  scientific  research  and  development  tax  credits  of  $7,478  and  $6,319,  respectively,  which  are  available  to  reduce  future  taxes
payable with expiries from 2019 through 2038. The benefit of these expenditures and tax credits has not been recorded in the accounts.

As  at  December  31,  2019,  the  Company  had  obligations  to  make  future  payments,  representing  significant  research  and  development  contracts  and  other
commitments that are known and committed in the amount of approximately $15,327. Most of these agreements are cancellable by the Company with notice.
These commitments include agreements for clinical trials, sponsored research, manufacturing and preclinical studies. The Company also has minimum lease
payments for operating lease commitments, primarily for its office and laboratory leases, in the amount of $349 over the next 12 months, $818 from 12 to 60
months, and $231 thereafter. The Company has potential future payments of $1,121 related to retention agreements for key employees.

The Company enters into research, development and license agreements in the ordinary course of business where the Company receives research services and
rights  to  proprietary  technologies.  Milestone  and  royalty  payments  that  may  become  due  under  various  agreements  are  dependent  on,  among  other  factors,
clinical trials, regulatory approvals and ultimately the successful development of a new drug, the outcome and timing of which are uncertain. Under the license
agreement for SIRPαFc, the Company has future contingent milestones payable of $19 related to successful patent grants, $154 and $231 on the first patient
dosed in phase 2 and 3 trials, respectively, regulatory milestones on their first achievement totalling $3,846, and royalties on commercial sales.

Under  the  May  2019  amending  agreement,  Trillium  and  the  former  Fluorinov  shareholders  will  share  50%  of  net  revenues  relating  to  Fluorinov’s  legacy
products.

The Company has two agreements with Catalent Pharma Solutions pursuant to which Trillium acquired the right to use a proprietary expression system for the
manufacture of two SIRPαFc constructs. Consideration for each license includes potential pre-marketing approval milestones of up to $875 and aggregate sales
milestone payments of up to $28,750.

14. Commitments and contingencies (continued)

The  Company  periodically  enters  into  research  and  license  agreements  with  third  parties  that  include  indemnification  provisions  customary  in  the  industry.
These  guarantees  generally  require  the  Company  to  compensate  the  other  party  for  certain  damages  and  costs  incurred  as  a  result  of  claims  arising  from
research and development activities undertaken by or on behalf of the Company. In some cases, the maximum potential amount of future payments that could
be  required  under  these  indemnification  provisions  could  be  unlimited.  These  indemnification  provisions  generally  survive  termination  of  the  underlying
agreement. The nature of the indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could
be  required  to  pay.  Historically,  the  Company  has  not  made  any  indemnification  payments  under  such  agreements  and  no  amount  has  been  accrued  in  the
consolidated financial statements with respect to these indemnification obligations.

15. Related parties

For  the  years  ended  December  31,  2019  and  2018,  the  key  management  personnel  of  the  Company  were  the  board  of  directors,  Executive  Chair,  Chief
Executive Officer, Chief Medical Officer, Chief Scientific Officer, Chief Financial Officer and the Chief Development Officer.

shares of the Company.

Outstanding  balances  with  related  parties  at  year-end  are  unsecured,  interest  free  and  settlement  occurs  in  cash.  There  have  been  no  guarantees  provided  or
received for any related party receivables or payables. For the year ended December 31, 2019, $nil was paid to a director for consulting fees (2018 – $58).

16. Operating segment

The Company has a single operating segment, the research and development therapies for the treatment of cancer. A majority of the Company’s operations,
assets and employees are in Canada.

17. Management of capital

The Company defines its capital as share capital, warrants and contributed surplus. The Company’s objectives when managing capital are to ensure there are
sufficient funds available to carry out its research and development programs. To date, these programs have been funded primarily through the sale of equity
securities  and  the  exercise  of  warrants.  The  Company  also  sources  non-dilutive  funding  by  accessing  grants,  government  assistance  and  tax  incentives,  and
through partnerships with corporations and research institutions. The Company uses budgets and purchasing controls to manage its costs. The Company is not
exposed to any externally imposed capital requirements.

18. Financial instruments

Fair value

IFRS 13 Fair Value Measurement provides a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or
unobservable.  Observable  inputs  are  those  that  reflect  market  data  obtained  from  independent  sources,  while  unobservable  inputs  reflect  the  Company’s
assumptions with respect to how market participants would price an asset or liability. These two inputs used to measure fair value fall into the following three
different levels of the fair value hierarchy:

Level 1

Level 2

Level 3

Quoted prices in active markets for identical instruments that are observable.
Quoted  prices  in  active  markets  for  similar  instruments;  inputs  other  than  quoted  prices  that  are  observable  and
derived from or corroborated by observable market data.
Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

The hierarchy requires the use of observable market data when available.

The Company has classified cash and cash equivalents as Level 1. The marketable securities and loan payable have been classified as Level 2. The warrant
liability has been classified as Level 3.

Cash and cash equivalents, marketable securities, amounts receivable, accounts payable and accrued liabilities, and other current liabilities, due within one year,
are all short-term in nature and, as such, their carrying values approximate fair values. Marketable securities, which primarily include guaranteed investment
certificates held by the Company, are valued at amortized cost.

Risks

The Company has exposure to credit risk, liquidity risk, interest rate risk and currency risk. The Company’s board of directors has overall responsibility for the
establishment and oversight of the Company’s risk management framework. The Audit Committee of the board of directors is responsible for reviewing the
Company’s risk management policies.

(a) Credit risk

Credit risk is the risk of financial loss to the Company if a counterparty to a financial instrument fails to meet its contractual obligations, and arises principally
from  the  Company’s  cash  and  cash  equivalents,  marketable  securities  and  amounts  receivable.  The  carrying  amount  of  these  financial  assets  represents  the
maximum credit exposure. The Company follows an investment policy to mitigate against the deterioration of principal and to enhance the Company’s ability to
meet its liquidity needs. Cash is on deposit with major Canadian chartered banks and the Company invests in high-grade short-term instruments.

(b) Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company is a development stage company and
is reliant on external fundraising to support its operations. Once funds have been raised, the Company manages its liquidity risk by investing in cash and short-
term instruments to provide regular cash flow for current operations. It also manages liquidity risk by continuously monitoring actual and projected cash flows.
The board of directors reviews and approves the Company’s operating and capital budgets, as well as any material transactions not in the ordinary course of
business.

(c) Interest rate risk

Interest  rate  risk  is  the  risk  that  the  fair  value  or  future  cash  flows  of  a  financial  instrument  will  fluctuate  because  of  changes  in  market  interest  rates.  The
Company holds its cash in bank accounts or high-interest savings accounts that have a variable rate of interest. The Company manages its interest rate risk by
holding  highly  liquid  short-term  instruments  and  by  holding  its  investments  to  maturity,  where  possible.  The  Company  earned  interest  income  for  the  years
ended  December  31,  2019  and  2018  of  $614  and  $839,  respectively.  Therefore,  a  100  basis  points  change  in  the  average  interest  rate  for  the  years  ended
December 31, 2019 and 2018 would have a net impact on finance income of $6 and $8, respectively.

18. Financial instruments (continued)

(d) Currency risk

The Company is exposed to currency risk related to the fluctuation of foreign exchange rates and the degree of volatility of those rates. Currency risk is limited
to the portion of the Company’s business transactions denominated in currencies other than the Canadian dollar, which are primarily expenses in U.S. dollars.
As at December 31, 2019 and 2018, the Company held U.S. dollar cash and cash equivalents and marketable securities in the amount of $20,920 and $30,208,
and  had  U.S.  dollar  denominated  accounts  payable  and  accrued  liabilities  in  the  amount  of  $7,608  and  $7,404,  respectively.  Therefore,  a  1%  change  in  the
foreign exchange rate would have a net impact on finance costs as at December 31, 2019 and December 31, 2018 of $105 and $218, respectively.

U.S. dollar expenses for the years ended December 31, 2019 and 2018 were approximately $18,003 and $18,050, respectively. Varying the U.S. exchange rate
for the years ended December 31, 2019 and 2018 to reflect a 1% strengthening of the Canadian dollar would have decreased the net loss by approximately $180
