2007 Annual Report

Letter to Stockholders

Notice of 2008 Annual Meeting of Stockholders 
and Proxy Statement

Report on Form 10-K

To Our Stockholders: 

2007 was a very successful year for Juniper Networks on many fronts, both financially and 

strategically.  First, the financial success:  the Company posted $2.84 billion in revenue, ahead of 

our expectations and 23% above 2006.  Our revenue growth rates compared to the prior year 

accelerated in each successive quarter during the year, and our fourth quarter marked the 

highest single revenue quarter in Juniper history.  We delivered on the bottom line as well, 

posting $360.8 million, or $0.62 per diluted share, in GAAP net earnings, as we demonstrated 

improved leverage in our business model exiting 2007.  We ended the year with over $2 billion in 

cash and cash equivalents. 

These results demonstrated that Juniper executed on its two key strategic goals for 2007: 

-  build revenue momentum in the high-performance segment of the networking market; and,  
-  begin to expand operating margins as we focus on establishing operating excellence and 

progress toward our targeted profitability model. 

In 2008 we are poised to make further gains on both of those objectives. 

We are in this position because Juniper is pursuing a strategy that is aligned closely with the 

evolution in global network infrastructure.  Our business is no longer so much about the individual 

pieces – core, edge, aggregation, access – nor is it about building specific products to the needs 

of customer verticals – service providers, enterprises and public sector agencies.  We serve all 

these customers with customized solutions, but each solution is built with an underlying focus on 

total network performance, supported by an infrastructure footprint that provides fast, reliable and 

secure access to applications and services at global scale.  Underlying those capabilities is 

JUNOS, our single-source network operating system that runs across our network infrastructure.  

We call our approach high-performance networking – and it is the DNA of our company. 

In fact, it is also our core strength in the marketplace, and the market itself has helped validate 

that assertion.  We serve each of the top 65 network service providers around the world.  We 

serve 96 of the Fortune 100 enterprises.  We serve the U.S. government and many NATO 

governments, as well as others around the globe.   

Many of these customers are taking advantage of our broad portfolio of high-performance 

networking infrastructure offerings, including the MX-series family of Ethernet service and multi-

service edge routers.  The MX-series established itself upon its introduction in 2007 as one of our 

fastest ramping new product families ever and is at the forefront of efficient and cost-effective 

Ethernet networks and services, providing the performance and scalability to such applications as 

Internet Protocol TV (IPTV) and video-on-demand.  Products like the MX960, the largest capacity 

and highest density Ethernet platform for carriers available today, and the recently introduced 

MX480 and MX240 play right into our high-performance focus. 

We also continue to win customer acceptance and industry accolades for products like our T1600 

multi-terabit core router, the industry’s highest throughput and most energy efficient core router, 
and recipient of Internet Telephony’s 2007 product of the year designation.  Revenue from our T-

series products grew 55% in the fourth quarter compared to Q4 of the prior year and the product 

group is now deployed in more than 200 production networks globally.  

In addition to the momentum we’ve established with these new key product lines, at the 

conclusion of 2007 we achieved quarterly profitability on a non-GAAP basis in our Service Layer 

Technology (SLT) segment.  We crossed the half-billion dollar revenue mark in this business in 

2007 as our products continued to gain market share.  We believe our firewall, SSL VPN and 

WAN Optimization solutions will continue to be well-received by our customers.  

So, our technology, our market position and our recognition as a leader by customers and 

industry followers are all as strong as they ever have been for Juniper.  However, we also need to 

turn the opportunities these positions create into increasing value for stockholders.  Juniper 

performed well in 2007, but it can perform better.  And our team is hard at work on making that 

happen. 

During 2007 we began implementing a series of company-wide operating initiatives---we call 

them our 4 Ps, for planning, productivity, processes and people.  Collectively our efforts are 

focused on supporting the scalability of our business in a number of ways:  optimally aligning our 

resources – human and financial -- with our R&D and marketing activities; finding and executing 

on productivity improvement opportunities in our sales and service organizations; leveraging the 

capabilities of our engineering organization across all product groups; and transforming core 

systems and processes to create efficiencies in areas like product design, customer support and 

enterprise resource planning. 

These initiatives underpin a business focus on strengthening our operating profit margins.  The 

later part of 2007 yielded initial results that give us a good start on that path, but much remains to 

be done.  We will continue to focus relentlessly on execution and operational excellence as we 

progress toward our performance goals. 

Along the way, we will continue to build on our position as the leader in high performance 

networking.  Juniper is only a 12-year old company, yet it has and continues to play a critical role 

in defining how to deliver optimal network performance in a global information environment 

demanding ever-increasing bandwidth and speed.  The good news is that seeing and meeting 

these challenges happens to be our organization’s underlying strength.  By focusing on the open 

architecture that we believe will drive optimal network performance, and tailoring our solutions to 

customers whether they are operators or users of those networks, we expect to continue leading 

the way. 

Our confidence in these goals is made stronger by the more than 6,000 talented people 

throughout Juniper’s global organizations who embody our high-performance DNA approach.  I 

want to thank them for their great work, as well as our partners, customers, suppliers, and 

stockholders for their support of Juniper Networks. 

Sincerely, 

Scott Kriens 

Chairman and Chief Executive Officer

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING

Q: Why am I receiving these materials?

A: The Board of Directors (the “Board”) of Juniper Networks, Inc., a Delaware corporation (“we”, “Juniper
Networks” or the “Company”), is providing these proxy materials to you in connection with Juniper Networks’
annual meeting of stockholders, which will take place on May 21, 2008. As a stockholder as of March 24, 2008,
the record date, you are invited to attend the annual meeting and are entitled to and requested to vote on the
items of business described in this proxy statement.

Q: What information is contained in this proxy statement?

A: The information included in this proxy statement relates to the proposals to be voted on at the annual meeting,
the voting process, the compensation of directors and executive officers, and certain other required information.

Q: How may I obtain Juniper Networks’ 10-K?

A: A copy of our 2007 Annual Report on Form 10-K is enclosed.

Stockholders may request another free copy of the 2007 Form 10-K from our principal executive offices at:

Juniper Networks, Inc.
Attn: Investor Relations
1194 North Mathilda Avenue
Sunnyvale, CA 94089
(408) 745-2000

A copy of our 2007 Annual Report on Form 10-K is also available on the website of the Securities and Exchange
Commission. You can reach this website by going to the Investor Relations Center on our Website, and clicking

http://www.juniper.net/company/investor_relations/

We will also furnish any exhibit to the 2007 Annual Report on Form 10-K if specifically requested in writing.

Q: What items of business will be voted on at the annual meeting?

A: The items of business scheduled to be voted on at the annual meeting are:

• The election of two Class III directors;

• To approve the Juniper Networks, Inc. 2008 Employee Stock Purchase Plan (the “2008 ESPP”);

• The ratification of Ernst & Young LLP, an independent registered public accounting firm, as auditors for the

fiscal year ending December 31, 2008; and

We will also consider other business that properly comes before the annual meeting.

Q: How does the Board recommend that I vote?

A: Our Board recommends that you vote your shares “FOR” each of the nominees to the Board, “FOR” the
approval of the 2008 ESPP, and “FOR” the ratification of Ernst & Young LLP, an independent registered public
accounting firm as auditors for the fiscal year ending December 31, 2008.

Q: What shares can I vote?

A: Each share of Juniper Networks common stock issued and outstanding as of the close of business on March 24,
2008, (the “Record Date”), is entitled to be voted on all items being voted upon at the annual meeting. You may
vote all shares owned by you as of the Record Date, including (1) shares held directly in your name as the
stockholder of record and (2) shares held for you as the beneficial owner through a broker, trustee or other
nominee such as a bank. More information on how to vote these shares is contained in this proxy statement. On
the Record Date we had approximately 524,225,748 shares of common stock issued and outstanding.

1

Q: What is the difference between holding shares as a stockholder of record and as a beneficial owner?

A: Most Juniper Networks stockholders hold their shares through a broker or other nominee rather than directly in
their own name. As summarized below, there are some distinctions between shares held of record and those
owned beneficially, which may affect your ability to vote your shares.

Stockholder of Record

If your shares are registered directly in your name with Juniper Networks’ transfer agent, Wells Fargo
Shareowner Services, you are considered, with respect to those shares, the stockholder of record, and these
proxy materials are being sent directly to you by Juniper Networks. As the stockholder of record, you have the
right to grant your voting proxy directly to Juniper Networks or to vote in person at the meeting. We have
enclosed or sent a proxy card for you to use.

Beneficial Owner

If your shares are held in a brokerage account or by another nominee, you are considered the beneficial owner of
shares held in street name, and these proxy materials are being forwarded to you together with a voting
instruction card. As the beneficial owner, you have the right to direct your broker, trustee or nominee how to
vote and are also invited to attend the annual meeting.

Since a beneficial owner is not the stockholder of record, you may not vote these shares in person at the meeting
unless you obtain a “legal proxy” from the broker, trustee or nominee that holds your shares, giving you the right
to vote the shares at the meeting. Your broker, trustee or nominee has enclosed or provided voting instructions
for you to use in directing the broker, trustee or nominee how to vote your shares.

Q: How can I attend the annual meeting?

A: You are entitled to attend the annual meeting only if you were a Juniper Networks stockholder as of the close of
business on March 24, 2008 or you hold a valid proxy for the annual meeting. You should be prepared to present
valid government-issued photo identification for admittance. In addition, if you are a stockholder of record,
your name will be verified against the list of stockholders of record on the record date prior to your being
admitted to the annual meeting. If you are not a stockholder of record but hold shares through a broker or
nominee (i.e., in street name), you should provide proof of beneficial ownership on the record date, such as your
most recent account statement prior to March 24, 2008, a copy of the voting instruction card provided by your
broker, trustee or nominee, or other similar evidence of ownership. If you do not provide valid government-
issued photo identification or comply with the other procedures outlined above upon request, you will not be
admitted to the annual meeting.

The meeting will begin promptly at 9:00 a.m., Pacific time. Check-in will begin at 8:30 a.m., and you should
allow ample time for the check-in procedures.

Q: How can I vote my shares in person at the annual meeting?

A: Shares held in your name as the stockholder of record may be voted in person at the annual meeting. Shares held
beneficially in street name may be voted in person only if you obtain a legal proxy from the broker, trustee or
nominee that holds your shares giving you the right to vote the shares. Even if you plan to attend the annual
meeting, you may also submit your proxy or voting instructions as described below so that your vote will be
counted if you later decide not to attend the meeting.

Q: How can I vote my shares without attending the annual meeting?

A: Whether you hold shares directly as the stockholder of record or beneficially in street name, you may direct how
your shares are voted without attending the meeting. If you are a stockholder of record, you may vote by
submitting a proxy. If you hold shares beneficially in street name, you may vote by submitting voting
instructions to your broker, trustee or nominee. For directions on how to vote, please refer to the instructions
below and those included on your proxy card or, for shares held beneficially in street name, the voting
instruction card provided by your broker, trustee or nominee.

2

By Internet — Stockholders of record of Juniper Networks common stock with Internet access may submit
proxies by following the “Vote by Internet” instructions on their proxy cards. Most Juniper Networks
stockholders who hold shares beneficially in street name may vote by accessing the website specified on
the voting instruction cards provided by their brokers, trustee or nominees. Please check the voting instruction
card for Internet voting availability.

By Telephone — Stockholders of record of Juniper Networks common stock who live in the United States or
Canada may submit proxies by following the “Vote by Phone” instructions on their proxy cards. Most Juniper
Networks stockholders who hold shares beneficially in street name and live in the United States or Canada may
vote by phone by calling the number specified on the voting instruction cards provided by their brokers, trustee
or nominees. Please check the voting instruction card for telephone voting availability.

By Mail — Stockholders of record of Juniper Networks common stock may submit proxies by completing,
signing and dating their proxy cards and mailing them in the accompanying pre-addressed envelopes. Juniper
Networks stockholders who hold shares beneficially in street name may vote by mail by completing, signing
and dating the voting instruction cards provided and mailing them in the accompanying pre-addressed
envelopes.

Q: Can I change my vote or otherwise revoke my proxy?

A: You may change your vote at any time prior to the vote at the annual meeting. If you are the stockholder of
record, you may change your vote by granting a new proxy bearing a later date (which automatically revokes the
earlier proxy), by providing a written notice of revocation to the Juniper Networks Corporate Secretary prior to
your shares being voted, or by attending the annual meeting and voting in person. Attendance at the meeting
will not cause your previously granted proxy to be revoked unless you specifically so request. For shares you
hold beneficially in street name, you may change your vote by submitting new voting instructions to your
broker, trustee or nominee, or, if you have obtained a legal proxy from your broker or nominee giving you the
right to vote your shares, by attending the meeting and voting in person.

Q: How many shares must be present or represented to conduct business at the annual meeting?

A: The quorum requirement for holding the annual meeting and transacting business is that holders of a majority of
shares of Juniper Networks common stock entitled to vote must be present in person or represented by proxy.
Both abstentions and broker non-votes are counted for the purpose of determining the presence of a quorum.

Q: Will my shares be voted if I do not return my proxy card?

A: If your shares are held in street name, your broker may, under certain circumstances, vote your shares.
Brokerage firms have authority to vote client’s unvoted shares on some “routine” matters. If you do not give a
proxy to vote your shares, your broker may either (1) vote your shares on “routine” matters or (2) leave your
shares unvoted. In addition, the terms of the agreement with your broker may grant your broker discretionary
authority to vote your shares.

Q: How are votes counted?

A: In the election of directors, you may vote “FOR” all of the nominees or your vote may be “WITHHELD” with

respect to one or more of the nominees.

For the other items of business, you may vote “FOR,” “AGAINST” or “ABSTAIN.” If you “ABSTAIN,” the
abstention has the same effect as a vote “AGAINST.”

If you provide specific instructions with regard to certain items, your shares will be voted as you instruct on such
items. If you sign your proxy card or voting instruction card without giving specific instructions, your shares
will be voted in accordance with the recommendations of the Board (“FOR” all of Juniper Networks’ nominees
to the Board, “FOR” approval of the 2008 ESPP and “FOR” ratification of the independent registered public
accounting firm) and in the discretion of the proxy holders as to any other matters that may properly come
before the annual meeting.

Q: What is the voting requirement to approve each of the proposals?

A: In the election of directors, the two nominees receiving the highest number of “FOR” votes at the annual
meeting will be elected. The proposals for the approval of the 2008 ESPP and the ratification of the independent
registered public accounting firm requires the affirmative “FOR” vote of a majority of those shares present in
person or represented by proxy and entitled to vote on each proposal at the annual meeting. If you hold shares
beneficially in street name and do not provide your broker with voting instructions, your shares may constitute
“broker non-votes.” Generally, broker non-votes occur on a matter when a broker is not permitted to vote on that
matter without instructions from the beneficial owner and instructions are not given. In tabulating the voting
result for any particular proposal, shares that constitute broker non-votes are not considered entitled to vote on
that proposal. Thus, broker non-votes will not affect the outcome of any matter being voted on at the meeting,
assuming that a quorum is obtained. Abstentions have the same effect as votes against the matter.

Q: Is cumulative voting permitted for the election of directors?

A: No. Each share of common stock outstanding as of the close of business on the Record Date is entitled to one

vote.

Q: What happens if additional matters are presented at the annual meeting?

A: Other than the three items of business described in this proxy statement, we are not aware of any other business
to be acted upon at the annual meeting. If you grant a proxy, the persons named as proxyholders, Robyn
Denholm and Mitchell Gaynor, will have the discretion to vote your shares on any additional matters properly
presented for a vote at the meeting. If for any unforeseen reason any of our nominees is not available as a
candidate for director, the persons named as proxy holders will vote your proxy for such other candidate or
candidates as may be nominated by the Board of Directors.

Q: What should I do if I receive more than one set of voting materials?

A: You may receive more than one set of voting materials, including multiple copies of this proxy statement and
multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one
brokerage account, you may receive a separate voting instruction card for each brokerage account in which you
hold shares. If you are a stockholder of record and your shares are registered in more than one name, you will
receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction
card that you receive.

Q: How may I obtain a separate set of voting materials?

A: If you share an address with another stockholder, you may receive only one set of proxy materials (including our
letter to stockholders, 2007 Annual Report on Form 10-K and proxy statement) unless you have provided
contrary instructions. If you wish to receive a separate set of proxy materials now or in the future, you may write
or call us to request a separate copy of these materials from:

Juniper Networks, Inc.
Attn: Investor Relations
1194 North Mathilda Avenue
Sunnyvale, CA 94089
(408) 745-2000
http://www.juniper.net/company/investor_relations/

Similarly, if you share an address with another stockholder and have received multiple copies of our proxy
materials, you may write or call us at the above address and phone number to request delivery of a single copy of
these materials.

Q: Who will bear the cost of soliciting votes for the annual meeting?

A: Juniper Networks is making this solicitation and will pay the entire cost of preparing, assembling, printing,
mailing and distributing these proxy materials and soliciting votes. If you choose to access the proxy materials
and/or vote over the Internet, you are responsible for Internet access charges you may incur. If you choose to

4

vote by telephone, you are responsible for telephone charges you may incur. In addition to the mailing of these
proxy materials, the solicitation of proxies or votes may be made in person, by telephone or by electronic
communication by our directors, officers and employees, who will not receive any additional compensation for
such solicitation activities. We also have hired Morrow & Co. to assist us in the distribution of proxy materials
and the solicitation of votes described above. We will pay Morrow & Co. a fee of $5,000 plus customary costs
and expenses for these services. Upon request, we will also reimburse brokerage houses and other custodians,
nominees and fiduciaries for forwarding proxy and solicitation materials to stockholders.

Q: Where can I find the voting results of the annual meeting?

A: We intend to announce preliminary voting results at the annual meeting and publish final results in our quarterly

report on Form 10-Q for the second quarter of 2008.

Q: What is the deadline to propose actions for consideration or to nominate individuals to serve as directors?

A: Although the deadline for submitting proposals or director nominations for consideration at the 2008 annual
meeting has passed, you may submit proposals, including director nominations, for consideration at future
stockholder meetings.

Stockholder Proposals: For a stockholder proposal to be considered for inclusion in Juniper Networks’ proxy
statement for the annual meeting next year, the written proposal must be received by the Corporate Secretary of
Juniper Networks at our principal executive offices no later than December 19, 2008. If the date of next year’s
annual meeting is moved more than 30 days before or after the anniversary date of this year’s annual meeting,
the deadline for inclusion of proposals in Juniper Networks’ proxy statement is instead a reasonable time before
Juniper Networks begins to print and mail its proxy materials. Such proposals also will need to comply with
Securities and Exchange Commission regulations under Rule 14a-8 regarding the inclusion of stockholder
proposals in company-sponsored proxy materials. Proposals should be addressed to:

Juniper Networks, Inc.
Attn: Corporate Secretary
1194 North Mathilda Avenue
Sunnyvale, CA 94089
Fax: (408) 745-2100

For a stockholder proposal that is not intended to be included in Juniper Networks’ proxy statement under
Rule 14a-8, the stockholder must deliver a proxy statement and form of proxy to holders of a sufficient number
of shares of Juniper Networks common stock to approve that proposal, provide the information required by the
bylaws of Juniper Networks and give timely notice to the Corporate Secretary of Juniper Networks in
accordance with our bylaws, which, in general, require that the notice be received by the Corporate Secretary
of Juniper Networks not less than 120 days prior to the date of Juniper Networks proxy statement released to
stockholders in connection with the previous year’s annual meeting of stockholders, or by December 19, 2008
for the 2009 annual meeting.

Recommendation and Nomination of Director Candidates: The Nominating and Corporate Governance
Committee will consider both recommendations and nominations for candidates to the Board of Directors from
Qualifying Stockholders. A “Qualifying Stockholder” is a stockholder that has owned for a period of one year
prior to the date of the submission of the recommendation through the time of submission of the recommen-
dation at least 1% of the total common stock of the Company outstanding as of the last day of the calendar
month preceding the submission. A Qualifying Stockholder that desires to recommend a candidate for election
to the Board of Directors must direct the recommendation in writing to Juniper Networks, Inc., Corporate
Secretary, 1194 North Mathilda Avenue, Sunnyvale, California 94089-1206, and must include the candidate’s
name, home and business contact information, detailed biographical data and qualifications, information
regarding any relationships between the candidate and the Company within the last three years, written
evidence that the candidate is willing to serve as a director of the Company if nominated and elected and
evidence of the nominating person’s ownership of Company stock.

5

A stockholder that instead desires to nominate a person directly for election to the Board of Directors must meet
the deadlines and other requirements set forth in Section 2.5 of the Company’s bylaws and the rules and
regulations of the Securities and Exchange Commission. To be timely, such stockholder’s notice must be
delivered to or mailed and received by the Corporate Secretary of the Company not less than one hundred
twenty (120) days prior to the date of the Company’s proxy statement released to stockholders in connection
with the Company’s previous year’s annual meeting of stockholders. To be in proper form, a stockholder’s
notice to the Secretary shall set forth:

(i) the name and address of the stockholder who intends to make the nominations and the name and address

of the person or persons to be nominated;

(ii) a representation that the stockholder is a holder of record of stock of the Company entitled to vote at such
meeting and, if applicable, intends to appear in person or by proxy at the meeting to nominate the person
or persons specified in the notice;

(iii) if applicable, a description of all arrangements or understandings between the stockholder and each
nominee and any other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the stockholder;

(iv) such other information regarding each nominee as would be required to be included in a proxy statement
filed pursuant to the proxy rules of the Securities and Exchange Commission had the nominee been
nominated, or intended to be nominated by the Board of Directors; and

(v) if applicable, the consent of each nominee to serve as director of the Company if so elected.

Copy of Bylaws: You may contact the Juniper Networks Corporate Secretary at our principal executive offices
for a copy of the relevant bylaw provisions regarding the requirements for making stockholder proposals and
nominating director candidates.

CORPORATE GOVERNANCE PRINCIPLES AND BOARD MATTERS

Juniper Networks is committed to having sound corporate governance principles. Having such principles is essential to
running our business efficiently and to maintaining our integrity in the marketplace. Juniper Networks’ Corporate
Governance Standards and Worldwide Code of Business Conduct and Ethics applicable to all Juniper Networks employees,
officers, directors, contractors and agents are available at http://www.juniper.net/company/investor_relations/. Our World-
wide Code of Business Conduct and Ethics complies with the rules of the SEC, the listing standards of the NASDAQ Global
Select Market and Rule 406 of the Sarbanes-Oxley Act of 2002. Juniper Networks has also adopted procedures for
accounting and auditing matters in compliance with the listing standards of the NASDAQ Global Select Market. Concerns
relating to accounting, internal controls or auditing matters may be brought to the attention of either the Company’s
Concerns Committee (comprised of the Company’s Chief Financial Officer, General Counsel, Executive Vice President of
Human Resources, Corporate Controller and the Senior Director of Global Audit Services), or to the Audit Committee
directly. Concerns are handled in accordance with procedures established with respect to such matters. For information on
how to contact the Audit Committee directly, please see the section entitled “Stockholder Communications with the Board”
below.

Board Independence

Our Board of Directors (the “Board”) has determined that, except for Scott Kriens and Pradeep Sindhu, each of
whom is an executive officer of the company, each of the current directors has no material relationship with Juniper
Networks (either directly or as a partner, stockholder or officer of an organization that has a material relationship
with Juniper Networks) and is independent within the meaning of the NASDAQ Stock Market, Inc. (“NASDAQ”)
director independence standards. Furthermore, the Board has determined that each of the members of each of the
committees of the Board has no material relationship with Juniper Networks (either directly or as a partner,
stockholder or officer of an organization that has a material relationship with Juniper Networks) and is “inde-
pendent” within the meaning of the NASDAQ director independence standards, including in the case of the
members of the Audit Committee, the heightened “independence” standard required for such committee members
set forth in the applicable SEC rules. In making the determination of the independence of our directors, the Board
considered all transactions in which Juniper Networks and any director had any interest, including transactions
involving Juniper Networks and payments made to or from companies and entities in the ordinary course of
business where our directors serve as partners, directors or as a member of the executive management of the other
company. In particular, the Board considered transactions between Juniper Networks and each of Ariba, Inc., where
Mr. Robert Calderoni serves as President and Chief Executive Officer, and Pillsbury Winthrop Shaw Pittman LLP,
where Ms. Mary Cranston serves as Firm Senior Partner. We lease office space from Ariba, approximately two-
thirds of which is pursuant to an agreement originally entered into by NetScreen Technologies, Inc. and Ariba prior
to our acquisition of NetScreen in 2004. This agreement was negotiated and is maintained at arms-length, and we do
not believe it is material to the results of operations or business of Juniper Networks. In addition, Pillsbury was
retained by our Audit Committee as counsel to the Audit Committee in connection with their independent
investigation into our historical stock option practices, which investigation was substantially completed in
December 2006. Ms. Cranston joined our board in November 2007 and was not involved in Pillsbury’s repre-
sentation of Juniper Networks. In each case, the Board determined that the nature, size and circumstances of the
relationships between Juniper Networks and each of Ariba and Pillsbury did not preclude a determination of
independence of Mr. Calderoni or Ms. Cranston under applicable SEC and NASDAQ rules.

Board Structure and Committee Composition

As of December 31, 2007, our Board had 10 directors divided into three classes — Class I, Class II and
Class III — with a three-year term for each class. As of December 31, 2007, the classes were comprised as follows:

Class I
(Term Expires in 2009)

Scott Kriens
Stratton Sclavos
William R. Stensrud

Class II
(Term Expires in 2010)

Pradeep Sindhu
Robert M. Calderoni
Michael Rose

7

Class III
(Term Expires this Year)

Mary B. Cranston
Kenneth Goldman*
William R. Hearst III**
J. Michael Lawrie

*

In January 2008, Mr. Goldman resigned from the Board. Mr. Goldman’s decision to resign was due to his
appointment in 2007 as an executive officer of a competitor of Juniper Networks, and was not due to any
disagreement with Juniper Networks on any matters relating to our operations, policies or practices.

** In addition, in February 2008, Mr. Hearst informed the Board that he would retire from and not stand for re-
election to the Board effective upon the expiration of his current term in 2008. Mr. Hearst’s decision was not due
to any disagreement with Juniper Networks on any matters relating to our operations, policies or practices. As
such, he will not stand for re-election at the 2008 annual meeting.

The Board has a standing Audit Committee, Compensation Committee and Nominating and Corporate Governance
Committee. The membership during the last fiscal year and the function of each of the committees are described below.
Each of these committees operates under a written charter adopted by the Board. All of those committee charters are
available on Juniper Networks’ website at http://www.juniper.net/company/investor_relations/. In addition, the Board has a
Stock Committee comprised of the Chief Executive Officer, Chief Financial Officer and beginning in February 2007, a non-
employee director, currently Mr. Stensrud. The Stock Committee has authority to grant stock options and restricted stock
awards to employees who are not executive officers. During 2007, the Stock Committee held ten meetings, and took action
by written consent twice. The Board has also established special litigation, securities pricing and stock repurchase
committees for specific purposes, such as oversight of, litigation matters the issuance of securities or repurchases of our
common stock. During 2007, the Special Litigation Committee, consisting of Messrs. Lawrie and Rose, met four times and
the Stock Repurchase Committee, consisting of Messrs. Kriens, Calderoni, Goldman and Stensrud, met once. During 2007,
each incumbent director attended at least 75% of all Board and applicable committee meetings.

Audit Committee

The Audit Committee assists the Board in fulfilling its responsibilities for general oversight of the integrity of
Juniper Networks’ financial statements, Juniper Networks’ compliance with legal and regulatory requirements, the
independent registered public accounting firm’s qualifications and independence, the performance of Juniper
Networks’ internal audit function and independent registered public accounting firm, and risk assessment and risk
management. The Audit Committee works closely with management as well as our independent registered public
accounting firm. The Audit Committee has the authority to obtain advice and assistance from, and receive
appropriate funding from Juniper Networks for, outside legal, accounting or other advisors as the Audit Committee
deems necessary to carry out its duties.

The report of the Audit Committee is included herein on page 47. The charter of the Audit Committee is

available at http://www.juniper.net/company/investor_relations/.

Compensation Committee

The Compensation Committee discharges the Board’s responsibilities relating to compensation of our
executive officers, including evaluation of the CEO; produces an annual report on executive compensation,
including compensation discussion and analysis, for inclusion in Juniper Networks’ proxy statement and has overall
responsibility for approving and evaluating executive officer compensation plans. The Compensation Committee
also has responsibility for reviewing the overall equity award practices of the Company. The report of the
Compensation Committee is included herein beginning on page 39. The charter of the Compensation Committee is
available at http://www.juniper.net/company/investor_relations/.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee identifies individuals qualified to become Board
members, consistent with criteria approved by the Board; oversees the organization of the Board to discharge the
Board’s duties and responsibilities properly and efficiently; and identifies best practices and recommends corporate
governance principles, including giving proper attention and making effective responses to stockholder concerns
regarding corporate governance. The charter of the Nominating and Governance Committee is available at
http://www.juniper.net/company/investor_relations/.

Identification and Evaluation of Nominees for Directors

The Nominating and Corporate Governance Committee’s criteria and process for evaluating and identifying
the candidates that it selects, or recommends to the full Board for selection, as director nominees, are as follows:

• The Committee regularly reviews the current composition and size of the Board.

• The Committee reviews the qualifications of any candidates who have been properly recommended or
nominated by a stockholder, as well as those candidates who have been identified by management,
individual members of the Board or, if the Committee determines, a search firm. Such review may, in
the Committee’s discretion, include a review solely of information provided to the Committee or may also
include discussions with persons familiar with the candidate, an interview with the candidate or other actions
that the Committee deems proper.

• The Committee evaluates the performance of the Board as a whole and evaluates the qualifications of

individual members of the Board eligible for re-election at the annual meeting of stockholders.

• The Committee considers the suitability of each candidate, including the current members of the Board, in
light of the current size and composition of the Board. In evaluating the qualifications of the candidates, the
Committee considers many factors, including, issues of character, judgment, independence, age, expertise,

9

diversity of experience, length of service, other commitments, ability to serve on committees of the Board
and the like. The Committee evaluates such factors, among others, and does not assign any particular
weighting or priority to any of these factors. The Committee considers each individual candidate in the
context of the current perceived needs of the Board as a whole. While the Committee has not established
specific minimum qualifications for director candidates, the Committee believes that candidates and
nominees must reflect a Board that is comprised of directors who (i) are predominantly independent,
(ii) are of high integrity, (iii) have qualifications that will increase overall Board effectiveness and (iv) meet
other requirements as may be required by applicable rules, such as financial literacy or financial expertise
with respect to audit committee members.

• In evaluating and identifying candidates, the Committee has the authority to retain and terminate any third
party search firm that is used to identify director candidates, and has the authority to approve the fees and
retention terms of any search firm.

• After such review and consideration, the Committee selects, or recommends that the Board of Directors
select, the slate of director nominees, either at a meeting of the Committee at which a quorum is present or by
unanimous written consent of the Committee.

J. Michael Lawrie was appointed to the Board as a Class III director in February 2007. The recommendation
that Mr. Lawrie be considered for appointment to the Board was submitted to the Nominating and Corporate
Governance Committee by Mr. Kriens.

Michael J. Rose was appointed to the Board as a Class II director in July 2007. The recommendation that
Mr. Rose be considered for appointment to the Board was submitted to the Nominating and Corporate Governance
Committee by Mr. Kriens.

Mary B. Cranston was appointed to the Board as a Class III director in November 2007. The recommendation
that Ms. Cranston be considered for appointment to the Board was submitted to the Nominating and Corporate
Governance Committee by Mr. Sclavos.

Each of the nominees for re-election at the 2008 annual meeting was evaluated by the Nominating and
Corporate Governance Committee, recommended by the Committee to the Board for nomination and nominated by
the Board for re-election. In February 2008, Mr. Hearst informed the Board that he will retire from the Board upon
the expiration of his current term and will not stand for re-election at the 2008 annual meeting.

Stockholder Communications with the Board

Stockholders of Juniper Networks, Inc. and other parties interested in communicating with the Board may
contact any of our directors by writing to them by mail or express mail c/o Juniper Networks, Inc., 1194 North
Mathilda Avenue, Sunnyvale, California 94089-1206. The Nominating and Corporate Governance Committee of
the Board has approved a process for handling stockholder communications received by the Company. Under that
process, the General Counsel receives and logs stockholder communications directed to the Board and, unless
marked “confidential”, reviews all such correspondence and regularly (not less than quarterly) forwards to the
Board a summary of such correspondence and copies of such correspondence. Communications marked “con-
fidential” will be logged as received by the General Counsel and then will be forwarded to the addressee(s).

Policy on Director Attendance at Annual Meetings

Although we do not have a formal policy regarding attendance by members of the Board at our annual
meetings of stockholders, directors are encouraged to attend annual meetings of Juniper Networks stockholders.

PROPOSALS TO BE VOTED ON

PROPOSAL NO. 1

ELECTION OF DIRECTORS

There are two nominees for election to Class III of the Board this year — Mary B. Cranston and J. Michael
Lawrie. Each of the nominees is presently a member of the Board. Information regarding the business experience of
each nominee and the other members of the Board is provided below. Each of the Class III directors are elected to
serve a three-year term until the Company’s annual meeting in 2011 and until their respective successors is elected.
There are no family relationships among our executive officers and directors.

In February 2008, William R. Hearst III informed the Board that he will retire from the Board upon the
expiration of his current term and will not stand for re-election at the 2008 annual meeting. As of the date of this
proxy statement, we had not identified a suitable nominee to replace Mr. Hearst on the Board. Accordingly, at the
2008 annual meeting there will be fewer persons nominated for election as Class III directors than are authorized to
be elected under our current bylaws and no other nominations were submitted by the deadline for nominations.
Votes may not be cast in person or by proxy at the 2008 annual meeting for greater than two nominees to the Board.

If you sign your proxy or voting instruction card but do not give instructions with respect to the voting of
directors, your shares will be voted for the two persons recommended by the Board. If you wish to give specific
instructions with respect to the voting of directors, you may do so by indicating your instructions on your proxy or
voting instruction card.

Our Board recommends a vote “FOR” the election to the Board of Mary B. Cranston and J. Michael

Lawrie.

Vote Required

PROPOSAL NO. 2

APPROVAL OF THE JUNIPER NETWORKS, INC. 2008 EMPLOYEE STOCK
PURCHASE PLAN

The following is a summary of the principal provisions of the Juniper Networks, Inc. 2008 Employee Stock
Purchase Plan, or the 2008 ESPP. The 2008 ESPP was adopted to replace the 1999 Employee Stock Purchase Plan,
which is due to expire in early 2009. The 2008 ESPP is generally similar to the expiring plan. This summary is
qualified in its entirety by reference to the full text of the 2008 ESPP which is attached to this proxy statement as
Appendix A.

Purchase Plan Background

In February 2008, the Board of Directors adopted the 2008 ESPP, subject to approval by our stockholders. Each
offering under the 2008 ESPP will be for a period of six months and will consist of consecutive offering periods of
approximately six months in length. Offering periods begin on February 1 and August 1, or if such date is not a
“trading day” (as defined in the 2008 ESPP), the next trading day, with the first such offering period anticipated to
commence on February 1, 2009 (assuming stockholders approve the 2008 ESPP). Each participant will be granted
an option on the first day of the offering period and the option will be automatically exercised on the last day of each
offering period during the offering period using the contributions the participant has made for this purpose. The
purchase price for the common stock purchased under the 2008 ESPP is 85% of the lesser of the fair market value of
the common stock on the first business day of the applicable offering period and on the last business day of the
applicable offering period. The 2008 ESPPAdministrator (as described below) has the power to change the duration
of offering periods.

Our 1999 Employee Stock Purchase Plan is currently in effect, with the current offering period under that plan
having commenced on February 1, 2008 and scheduled to end no later than July 31, 2008. If the 2008 ESPP is
approved by our stockholders, we will terminate the 1999 Employee Stock Purchase Plan immediately following
the conclusion of the offering period ending January 30, 2009, and the remaining shares reserved for issuance
thereunder, which as of March 1, 2008 was 13,149,032 shares, would no longer be available under the 1999
Employee Stock Purchase Plan.

Shares Subject to the 2008 ESPP

The Board has reserved an aggregate of 12,000,000 shares of Juniper Networks common stock for issuance
under the 2008 ESPP. In contrast to the 1999 Employee Stock Purchase Plan, which had automatic annual increases
to the shares reserved under such plan, no further increases can be made to the shares reserved for issuance under the
2008 ESPP without the approval of our stockholders.

Administration

The 2008 ESPP may generally be administered by the Board or a committee of the Board (as applicable, the
“Administrator”). The Administrator has the authority to construe and interpret any of the provisions of the 2008
ESPP.

International Stock Purchase Rights

To provide us with greater flexibility in structuring our equity compensation programs for our non-U.S.
employees, the 2008 ESPP also permits us to grant our non-U.S. employees rights to purchase stock pursuant to
rules or sub-plans adopted by the Administrator in order to achieve tax, securities law or other compliance
objectives (“International Awards”). While the 2008 ESPP is intended to be an “employee stock purchase plan”
within the meaning of Section 423 of the Internal Revenue Code (“Section 423”), these International Awards will

17

not qualify under Section 423. See “Federal Tax Consequences” below for a discussion of tax consequences under
Section 423.

Eligibility

Employees generally are eligible to participate in the 2008 ESPP if they are customarily employed by Juniper
Networks or by a participating subsidiary for more than twenty (20) hours per week and more than five (5) months in
any calendar year. International Awards may be made to employees customarily employed for fewer hours or
months Eligible employees may select a rate of payroll deduction between 1% and 10% of their compensation and
are subject to certain maximum purchase limitations.

As of March 31, 2008, approximately 5,800 employees, including all of our executive officers, would be
eligible to participate in the 2008 ESPP. For the offering period under our 1999 Employee Stock Purchase Plan that
concluded on January 31, 2008, 3,540 employees actually participated in such offering.

Special Limitations

The 2008 ESPP imposes certain limitations upon a participant’s rights to acquire common stock, including the

following limitations:

• Purchase rights may not be granted to any individual who owns stock, including stock purchasable under any
outstanding purchase rights, possessing 5% or more of the total combined voting power or value of all
classes of stock of Juniper Networks or any of its affiliates;

• Purchase rights granted to a participant may not permit the individual to accrue the right to purchase our
common stock at an annual rate of more than $25,000, valued at the time each purchase right is granted; and

• Unless otherwise approved by the Administrator in advance for future offering periods, no participant will be
permitted to purchase during any twelve (12) month period more than six thousand (6,000) shares of the
Common Stock (subject to any adjustment pursuant to stock splits, recapitalizations, dividends or other
similar events).

Termination of Purchase Rights

A purchase right will terminate upon the participant’s election to withdraw from the 2008 ESPP. Any payroll
deductions that the participant may have made with respect to the terminated purchase right will be refunded to the
participant if the election to withdraw from the 2008 ESPP is received by Juniper Networks prior to the end of an
offering period. A participant’s election to withdraw from the 2008 ESPP is irrevocable, and the participant may not
rejoin the offering period for which the terminated purchase right was granted.

A purchase right will also terminate upon the participant’s termination of employment. Any payroll deductions
that the participant may have made during the offering period in which the termination occurs will be refunded to
the participant.

In addition, Juniper Networks has specifically reserved the right, exercisable in the sole discretion of the

Administrator to terminate the 2008 ESPP, or any offering period thereunder, at any time.

Stockholder Rights

No participant will have any stockholder rights with respect to the shares covered by his or her purchase rights
until the shares are actually purchased on the participant’s behalf. No adjustment will be made for dividends,
distributions or other rights for which the record date is prior to the date of the purchase.

18

Assignability

No purchase rights will be assignable or transferable by the participant, except by will or the laws of
inheritance following the participant’s death. Each purchase right will, during the lifetime of the participant, be
exercisable only by the participant.

Mergers, Consolidations and Change in Control

The 2008 ESPP provides that, in the event of the proposed dissolution or liquidation of Juniper Networks, the
offering period will terminate immediately prior to the consummation of the proposed action, provided that the
Administrator may, in its sole discretion, fix an earlier date for termination of the 2008 ESPP and provide each
participant the opportunity to purchase shares under the 2008 ESPP prior to the termination. The 2008 ESPP also
provides that, in the event of certain merger or “change-in-control” transactions, in the event that the successor
corporation refuses to assume or substitute for the option under an ongoing offering period, the offering period with
respect to which such option relates will be shortened by setting a new exercise date that occurs before the date of
the Company’s proposed merger or change in control.

Amendment of the Plan

The Administrator has the authority to amend, terminate or extend the term of the 2008 ESPP, except that

stockholder approval is required to increase the number of shares that may be issued under the 2008 ESPP.

The 2008 ESPP will terminate in 2028, on the twentieth anniversary of the date of its adoption by our Board,
unless terminated earlier under the terms of the 2008 ESPP. The effect of termination is that no new offering periods
will commence under the 2008 ESPP, but any outstanding offering periods will continue according to their terms.

Federal Tax Consequences

Except with respect to International Awards, the 2008 ESPP is intended to be an “employee stock purchase
plan” within the meaning of Section 423 of the Internal Revenue Code. Under such a plan, no taxable income will be
reportable by a participant, and no deductions will be allowable to Juniper Networks, as a result of the grant or
exercise of the purchase rights issued under the 2008 ESPP. Taxable income will not be recognized until there is a
sale or other disposition of the shares acquired under the 2008 ESPP or in the event the participant should die while
still owning the purchased shares.

If the participant sells or otherwise disposes of the purchased shares within two years after commencement of
the offering period during which those shares were purchased or within one year of the date of purchase, the
participant will recognize ordinary income in the year of sale or disposition equal to the amount by which the fair
market value of the shares on the purchase date exceeded the purchase price paid for those shares. If the participant
sells or disposes of the purchased shares more than two years after the commencement of the offering period in
which those shares were purchased and more than one year from the date of purchase, then the participant will
recognize ordinary income in the year of sale or disposition equal to the lesser of the amount by which the fair
market value of the shares on the sale or disposition date exceeded the purchase price paid for those shares or 15% of
the fair market value of the shares on the date of commencement of such offering period. Any additional gain upon
the disposition will be taxed as a capital gain.

If the participant still owns the purchased shares at the time of death, the lesser of the amount by which the fair
market value of the shares on the date of death exceeds the purchase price or 15% of the fair market value of the
shares on the date of commencement of the offering period during which those shares were purchased will
constitute ordinary income in the year of death.

19

If the purchased shares are sold or otherwise disposed of within two years after commencement of the offering
period during which those shares were purchased or within one year after the date of purchase, then Juniper
Networks will be entitled to an income tax deduction in the year of sale or disposition equal to the amount of
ordinary income recognized by the participant as a result of such sale or disposition. No deduction will be allowed in
any other case.

New Benefits Under the 2008 ESPP

Because awards to employees under the 2008 ESPP are based on voluntary contributions in amounts
determined by the participant, the benefits and amounts that will be received or allocated under the 2008 ESPP
are not determinable at this time. Therefore, we have not included a table reflecting such benefits or awards.

Based on their stockholdings as of March 1, 2008, (determined in accordance with Section 423 of the Code) all
of our named executive officers (as defined in “Compensation Discussion and Analysis” below) will be eligible to
participate in our 2008 ESPP, except for Robert R.B. Dykes who resigned from the Company in 2007 and
Stephen Elop who resigned from the Company in 2008. Only two of our named executive officers currently
participate in our 1999 Employee Stock Purchase Plan. None of our non-employee directors will be eligible to
participate in the 2008 ESPP.

The Board of Directors Recommends a Vote “FOR” Approval of the Juniper Networks, Inc. 2008

Employee Stock Purchase Plan.

If you sign your proxy or voting instruction card but do not give specific voting instructions, your shares will be
voted for the approval of the Juniper Networks, Inc. 2008 Employee Stock Purchase Plan, as recommended by the
Board.

Vote Required

Approval of the of the Juniper Networks, Inc. 2008 Employee Stock Purchase Plan requires the affirmative
vote of a majority of the shares of Juniper Networks common stock present in person or represented by proxy and
entitled to be voted at the meeting.

PROPOSAL NO. 3

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has appointed Ernst & Young LLP, an independent registered public
accounting firm, to audit Juniper Networks’ consolidated financial statements for the fiscal year ending December 31,
2008. During fiscal 2007, Ernst & Young served as Juniper Networks’ independent registered public accounting firm
and also provided certain tax and other audit related services. See “Principal Accountant Fees and Services” on
page 46. Representatives of Ernst & Young are expected to attend the annual meeting, where they are expected to be
available to respond to appropriate questions and, if they desire, to make a statement.

Our Board recommends a vote “FOR” the ratification of the appointment of Ernst & Young LLP, an
independent registered public accounting firm, as Juniper Networks’ auditors for the 2008 fiscal year. If the
appointment is not ratified, the Audit Committee will consider whether it should select other independent auditors.
Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different
independent registered public accounting firm as Juniper Networks’ independent auditors at any time during the
year if the Audit Committee determines that such a change would be in the Company’s and its stockholders’ best
interests.

If you sign your proxy or voting instruction card but do not give specific voting instructions, your shares will be
voted for the ratification of the appointment of Ernst & Young LLP, an independent registered public accounting
firm, as Juniper Networks’ auditors for the 2008 fiscal year, as recommended by the Board.

Vote Required

Ratification of the appointment of Ernst & Young LLP, an independent registered public accounting firm, as
auditors for fiscal 2008 requires the affirmative vote of a majority of the shares of Juniper Networks common stock
present in person or represented by proxy and entitled to be voted at the meeting.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors, executive officers
and holders of more than 10% of Juniper Networks Common Stock to file with the Securities and Exchange
Commission reports regarding their ownership and changes in ownership of our securities. We believe that, during
fiscal 2007, our directors, executive officers and 10% stockholders complied with all Section 16(a) filing
requirements. In making this statement, we have relied upon examination of the copies of Forms 3, 4 and 5,
and amendments thereto, provided to Juniper Networks and the written representations of its directors and executive
officers.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The Company’s Worldwide Code of Business Conduct and Ethics (the “Code”) requires that the Company’s
employees, officers and directors should avoid conducting Company business with a relative or significant other, or
with a business in which a relative or significant other is associated in any significant role (as used in the Code, a
“related party transaction”). If the related party transaction involves the Company’s directors or executive officers
or is determined by the Company’s Chief Financial Officer to be material to the Company (or if applicable SEC or
NASDAQ rules require approval by the Audit Committee), the Audit Committee of the Board, in accordance with
the Code and its charter, must review and approve the matter in writing in advance of any such related party
transactions.

The Company reimburses Mr. Kriens for ordinary operating costs relating to his use of his aircraft for business
purposes up to a maximum amount of $650,000 per year. In 2007 Mr. Kriens received approximately $352,000 in
such reimbursements.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Executive Compensation Philosophy and Objectives

The Compensation Committee of the Board of Directors (the “Committee”) recognizes that in order for the
Company to successfully develop, introduce, market and sell products, the Company must be able to attract, retain
and reward qualified executive officers who will be able to operate effectively in a high growth, complex
environment. In that regard, the Company must offer compensation that (a) is competitive in the industry;
(b) motivates executive officers to achieve the Company’s strategic business objectives; and (c) aligns the interests
of executive officers with the long-term interests of stockholders.

The Committee’s intention is to adopt compensation programs that encourage creation of long-term value for
stockholders, employee retention, and equity participation. The Committee’s approach is based on the philosophy
that a substantial portion of aggregate compensation for executive officers should be contingent upon the
Company’s overall performance and an individual’s contribution to the Company’s success in meeting certain
critical objectives. In this regard, the Committee historically targeted base salary at approximately the 50th per-
centile, or median, relative to competitive market practices, although actual base salaries may be higher or lower
than this targeted positioning. Incentive compensation and long term equity awards were intended to target overall
compensation at approximately the 50th percentile, although the financial performance of the Company and
changes in the market price of the Company’s Common Stock can result in total compensation above or below the
target.

Overview of Executive Compensation

Under the charter of the Compensation Committee, the Committee is comprised entirely of independent
directors and has the responsibility for approving compensation for those officers who are designated as reporting
officers under Section 16 of the Securities Exchange Act of 1934 (“Section 16 officers”). Generally, the types of
compensation and benefits provided to the Section 16 officers are also provided to other non-Section 16 officers
reporting to the Chief Executive Officer. Throughout this proxy statement, the individuals who served as the
Company’s Chief Executive Officer or Chief Financial Officer during 2007, as well as the other individuals
included in the Summary Compensation Table on page 40, are referred to as the “named executive officers”. All of
the named executive officers are Section 16 officers.

The Committee approves all compensation decisions for the Section 16 officers. The Committee has the
authority to engage its own advisors to assist it in carrying out its responsibilities and has approved the Company’s
retention of Mercer (US) Inc. (“Mercer”) to provide analysis, advice and guidance from with respect to compen-
sation. The Committee is free to replace its compensation advisors or retain additional advisors at any time. Mercer
assists the Committee by providing compensation information, analyzing various compensation alternatives and
data, and helping to develop recommendations regarding all awards to Section 16 officers. Mercer and Mercer
affiliates also provide other services to the Company, including U.S. benefits administration, consulting services
related to generally available Company benefit plans, and brokerage services for U.S. and international benefit
plans.

Mercer generally works with the Company’s Executive Vice President responsible for Human Resources and
the Company’s Senior Director of Compensation and Benefits. Mercer provides analysis to the Company and the
Committee regarding the Section 16 officer’s compensation relative to external market benchmarks. Mercer also
provides information to the Company and the Committee regarding compensation trends, compensation strategy
and structure of incentive programs.

The Chief Executive Officer annually reviews the performance of each Section 16 officer (other than the Chief
Executive Officer whose performance is reviewed by the Committee). As Chief Executive Officer, Mr. Scott Kriens
is responsible for making a recommendation regarding the salary, incentive target and equity awards for each
individual Section 16 officer other than himself, based on the analysis and guidance provided by the Committee’s
advisors and on his assessment of the performance of the individuals. He is assisted by the Executive Vice President,

25

Human Resources and the Senior Director of Compensation and Benefits in these recommendations to the
Committee regarding compensation for Section 16 officers. Performance factors considered in developing rec-
ommendations for the Committee include the applicable officer’s leadership, strategic planning, delivery of
financial results (if such officer is responsible for such results, such as a general manager of a business group), and
succession planning. Mr. Kriens takes an active part in the discussions at Committee meetings at which compen-
sation of his direct reports and the other Section 16 officers are discussed.

The Executive Vice President, Human Resources and the Senior Director of Compensation and Benefits make
the recommendation regarding the Chief Executive Officer’s compensation with the input and advice of the
Committee’s advisors. Performance factors considered in developing recommendations for the Committee include
Mr. Kriens’ leadership, strategic planning, delivery of financial results and succession planning. All decisions
regarding Mr. Kriens compensation are made by the Committee in executive session, without Mr. Kriens present.
The Committee considers, but is not in any way bound by, and frequently changes recommendations made by
Company management. Similarly, the conclusions reached and recommendations made by outside advisors can
also be accepted, rejected or modified by the Committee.

Assessing the Competitive Market for Talent

In making compensation decisions, the Committee takes into account many factors described below, including
the competitive market for executive talent. The Committee uses competitive market data to establish reference
points for evaluating compensation for Section 16 officers. As there is considerable variation in the compensation
amounts and methodologies used among companies and because no two companies possess the exact same
characteristics, size, structure, business, history and prospects, the Committee relies on a specific peer company
analysis of publicly-available data on a group of publicly-traded networking equipment and other high technology
companies (the “Peer Group”) and “market data” composed of a broad technology company sample. The
companies included in the Peer Group are ones which the Committee believes are similar in size and business
scope to Juniper Networks and companies with which Juniper Networks competes for talent. This list is periodically
reviewed and updated by the Committee to take into account changes in both the Company’s business and the
businesses of the peer companies. For 2007, the Peer Group consisted of the following companies: Adobe Systems,
Inc.; Autodesk, Inc.; Avaya, Inc.; BEA Systems, Inc.; BMC Software, Inc.; CA, Inc.; Corning, Inc.; Earthlink, Inc.;
eBay, Inc.; Intuit, Inc.; Network Appliance, Inc.; Symantec Corporation; Tellabs, Inc.; VeriSign, Inc.; and Yahoo,
Inc. Because of the variations between companies as to which individuals and roles compensation is disclosed, there
will not be available directly comparable information from each peer company with respect to each of our Section 16
officers or named executive officers.

For the 2007 annual compensation review completed by Mercer, the broad-based technology company data
was drawn from several sources, including: the Buck Executive High Technology Survey, the Radford Executive
Survey, the Watson Wyatt Report on Top Executive Compensation, and the Mercer Benchmark Database. For
corporate positions, data was collected for companies between $1 billion and $6 billion in sales revenue. For the
general managers who are compensated in part based on the performance of their respective business unit, the
Committee received survey data for Top Business Unit Executives scoped to the sales revenue size of each
respective business unit at the Company.

For 2008, the Peer Group was revised at the recommendation of Mercer to replace certain companies that were
acquired or were deemed to engage in atypical pay practices compared to the other members of the group. The 2008
Peer Group consisted of the following companies: Adobe Systems, Inc.; Autodesk, Inc.; Avaya, Inc.; BMC
Software, Inc.; CA, Inc.; Corning, Inc.; Earthlink, Inc.; eBay, Inc.; Harris Corporation; Intuit, Inc.; Network
Appliance, Inc.; Symantec Corporation; Tellabs, Inc.; VeriSign, Inc.; and UTStarcom, Inc. The data on the
compensation practices of the Peer Group is gathered through publicly available information. Because of the
variations between companies as to which individuals and roles compensation is disclosed, there will not be
available directly comparable information from each peer company with respect to each of our Section 16 officers
or named executive officers.

For the 2008 annual compensation review completed by Mercer, the broad-based technology company data
was drawn from several sources, including: the Buck Executive High Technology Survey and the Radford Executive

26

Survey. For corporate positions, data was collected for companies between $1 billion and $6 billion in sales revenue.
For the general managers who are compensated in part based on the performance of their respective business unit,
the Committee received survey data for Top Business Unit Executives scoped to the sales revenue size of each
respective business unit at the Company.

In addition to the market data sources discussed above, the Committee also considers other information and
factors in determining compensation for individual Section 16 officers including, internal consistency between
Juniper Networks employees, job performance, skills, prior experience, competitive job offers made to Juniper
Networks employees, recruiting offers made by Juniper Networks, and market conditions. Finally, in some cases,
the compensation for newly hired Section 16 officers may be determined based on the recruitment negotiations with
such individuals, and may reflect such factors as the amounts of compensation that the individual would forego by
joining Juniper Networks or the costs of relocation.

Elements of Executive Compensation

The principal components of compensation for Section 16 officers are:

• Base salary

• Performance-based cash incentive compensation

• Long-term equity incentive compensation, such as stock options, restricted stock units and performance

shares

• Employee benefits and perquisites

• Severance benefits

Juniper Networks has selected these elements of compensation because each is considered useful and/or
necessary to meet one or more of the principal objectives of our compensation policy. Base salary and employee
benefits are set with the goal of attracting employees by guaranteeing a minimum level of compensation for services
performed. Performance-based cash incentives are provided to incentivize or reward achievement of short-term or
annual performance goals. Long-term equity incentives are provided to align executive interests with those of our
stockholders and to promote achievement of long-term business objectives and retention of key talent.

The Committee reviews the compensation program on an annual basis. The Committee’s annual review is
primarily focused on the structure of the performance based incentive plans overall and, with respect to individual
Section 16 officers, on (i) base salary, (ii) total target cash compensation (base salary + performance based cash
incentive) and (iii) long-term equity incentive compensation and total direct compensation (total target cash comp +
long-term equity incentive). Except for the proposed Deferred Compensation Program and Executive Wellness
Program described below, the Company does not typically offer perquisites or employee benefits to Section 16
officers that are not also made available to employees on a broad basis. Severance benefits have been approved
either in connection with the negotiations to recruit individual executives or periodically as part of a program to
extend such benefits to Section 16 officers as a group. Accordingly, severance benefits, employee benefits and
perquisites are reviewed from time to time, but not annually, to ensure that benefit levels remain competitive and are
reasonable and not excessive.

Base Salary

Salaries are used to provide a fixed amount of compensation for the executive’s regular work. The Company
targets base salary levels for each position, on average, at the 50th percentile of similar positions based on
competitive market data. Some variation above or below the competitive median occurs when, in the judgment of
management and/or the Compensation Committee, as appropriate, the factors described above influence a different
positioning.

The salaries of the Section 16 officers are reviewed on an annual basis, as well as at the time of a promotion or

other change in responsibilities. The effective date of annual increases typically is April 1st of each year.

27

Pursuant to the 2007 annual compensation review and based on the performance of the company in 2006, no
changes were made to the base salaries of Mr. Edward Minshull, Mr. Robert Dykes. The Committee approved an
increase in base salary for Mr. Kriens intended to make his salary more competitive with the market and to place his
salary above that of our Chief Operating Officer. The Committee also approved an increase in salary and a decrease
in annual target incentive for Ms. Kim Perdikou in order to rebalance her cash compensation between salary (which
was below market) and annual cash incentive compensation (which was above market).

In January 2007, Mr. Stephen Elop joined the Company and in August 2007, Ms. Robyn Denholm joined the
Company. Their respective base salaries and other compensation were determined with reference to the competitive
market data discussed above and through negotiation.

Pursuant to the 2008 annual compensation review, no changes were made to the base salary of Mr. Minshull
because his salary was above the median percentile of the competitive market data. The Committee noted that this
was primarily due to the fact that Mr. Minshull is paid in British Pounds and exchange rates have impacted his
compensation relative to the other named executive officers. The base salaries of Mr. Kriens, Ms. Denholm and
Ms. Perdikou were increased by approximately 16.7%, 4.2% and 5%, respectively. The increases to the salaries of
Mr. Kriens and Ms. Perdikou were intended to bring their salaries closer to the median of the Peer Group. Even after
the adjustment, Mr. Kriens’ salary is substantially below the median. However, the Committee concluded that it
would continue to move his salary toward the median over multiple years rather than attempt to close this gap in one
large step. The increase to Ms. Denholm’s salary places her total target cash compensation slightly above the
median for the Peer Group and the Committee determined this was appropriate in light of Ms. Denholm’s
performance in 2007.

Performance-Based Cash Incentive Compensation

Target Incentives as a Percentage of Salary

As discussed above, the Company’s compensation objective is to have a significant portion of each Section 16
officer’s compensation tied to performance. To this end, the Company has established a target annual performance-
based cash incentive opportunity for each Section 16 officer expressed as a percent of base salary. In establishing the
amount of target incentive, the Committee takes into account the competitive market data, a desired positioning at
the market median, the individual’s role and contribution to performance, and internal consistency among
executives at a comparable level. The actual award earned may be higher or lower than this target incentive
amount based on company, business unit, and/or individual performance factors.

For 2007, taking into account the changes made to base salary and other factors discussed above, the
Committee determined that no changes be made to the target incentive (as a percentage of base salary) for
Mr. Kriens, Mr. Minshull or Mr. Dykes and they remained at 150%, 100% and 100%, respectively. With respect to
Ms. Perdikou, the Committee determined that in light of her review of total cash compensation market data, the mix
of cash compensation between base salary and variable incentive should be rebalanced. As a result, the amount of
target incentive was reduced from 100% to 75% of base salary for Ms. Perdikou.

In connection with their joining the Company, Mr. Elop’s target incentive was established at 125% of base
salary earned in 2007 and Ms. Denholm’s target incentive was established at 100% of base salary earned in 2007.
The Committee determined Mr. Elop’s target based on two factors. First, the Committee concluded that it was
desirable to use the 125% amount in order to weight Mr. Elop’s total cash compensation more heavily on
achievement of Company performance objectives than other executive officers (other than Mr. Kriens). Second, the
Committee determined that the target incentive percentage was consistent with the general compensation objective
of targeting Mr. Elop’s total cash compensation at approximately the median percentile for his position based on
competitive market data. The target incentive for Ms. Denholm placed her total cash compensation slightly above
the median percentile for her position based on the competitive market data, but the Committee determined that this
was necessary to recruit Ms. Denholm to join Juniper Networks, was consistent with the target incentive for the
Company’s prior Chief Financial Officer and was consistent with the opportunities for other senior executives with
comparable positions.

28

In 2008, the Company’s objective was to target total cash compensation at approximately the market median of
the Peer Group. Taking into account the changes made to base salary discussed above and the Peer Group data for
total cash compensation, the Committee determined that no changes be made to the target incentive percentages for
the Company’s named executive officers.

Annual Incentive Plans

Each year an annual incentive plan is established for Section 16 officers in order to reward those individuals
based on performance against various business objectives for that year or for a portion of that year, as described
below. For 2007, the Company altered its executive short-term incentive plan from a six month plan to an annual
plan. The Company took this action to align its short-term incentive plan with market practice. In addition, the
Company believes that achievement of the Company’s business plan and near term business objectives are best
effectuated through a cash incentive plan tied to performance goals established for a period of one year. Because of
the rapidly changing industry in which the Company competes, the Company believes that by establishing goals
that are measured over an annual basis, the goals can be established with greater specificity and linkage to the
operating plan objectives and with less risk of subsequent revision than if objectives were based on longer
measurement periods. The Committee also believes that goals that can be achieved over an annual period are more
effective at motivating performance and promoting retention than goals which take a longer time to achieve and are
therefore inherently less under the control of the individual to accomplish. Moreover, the Company also believes
that establishing an annual plan provides the Company with the flexibility to adjust the structure and objectives of its
plan to meet changes in the Company’s business and competitive environment.

To promote achievement of longer term objectives, the Company relies on equity incentives discussed in more

detail below.

2007 Annual Incentive Plan. For the 2007 fiscal year, the Committee approved the 2007 Annual Incentive
Plan (the “2007 AIP”) for Section 16 officers. Under the 2007 AIP, each participant is eligible to receive an annual
incentive bonus once per year following the end of the year based on achievement of specified objectives
established at the beginning of the year. The Company believes that the primary performance measurements should
be based on achieving key financial targets tied to the Company’s annual operating plan. The incentive is based 50%
on the Company’s revenue results, 30% on the Company’s non-GAAP operating income results and 20% on
achieving other specified strategic goals, such as employee engagement and leadership development. However, in
the case of a general manager of a business group, such as Ms. Kim Perdikou, Executive Vice President and General
Manager Infrastructure Products Group, the revenue and operating income factors are based half on achieving the
Company’s revenue and non-GAAP operating income targets and half on achieving the applicable business group’s
revenue and non-GAAP contribution margin targets. The incentive amounts are calculated and paid after the end of
the year. The amounts paid depend on the level of achievement against the objectives and, with respect to the
revenue and operating income objectives, range between zero and 200% of the target incentive. With respect to the
specified strategic goals, payments range between zero and 100% of the target incentive. However, no payment is
earned for any component if less than 80% of the operating income objective is achieved. At 80% of the objective,
30% of the applicable component is earned; achievement of 100% of the objective results in 100% of the component
earned; and if 120% of the revenue or operating income objective is achieved, 200% of that component is earned. At
the time the Committee set the performance goals for the participants under the 2007 AIP, it believed that they were
achievable but only with significant effort.

Upon completion of the measurement period for 2007, the Committee reviewed the performance of the
Company, each applicable business group and each Section 16 officer to verify and approve the calculations of the
amounts to be paid under the 2007 AIP.

29

Payments to Section named executive officers under the 2007 Bonus Plan ranged between 109% and 117% of
the individual’s target bonus for year. The following table summarizes the payments for the Company’s named
executive officers:

2008 Annual Incentive Plan. For the 2008 fiscal year, the Committee approved the 2008 Annual Incentive
Plan (the “2008 AIP”) for Section 16 officers. Under the 2008 AIP, each participant is eligible to receive an annual
incentive bonus once per year following the end of the year based on achievement of specified objectives
established at the beginning of the year. The Company believes that the primary performance measurements should
be based on achieving key financial targets tied to the Company’s annual operating plan. The incentive is based 50%
on the Company’s revenue results, 30% on the Company’s non-GAAP operating income results and 20% on
achieving other specified strategic goals, such as employee engagement and leadership development. However, in
the case of a general manager of a business group, the revenue and operating income factors are based half on
achieving the Company’s revenue and non-GAAP operating income targets and half on achieving the applicable
business group’s revenue and non-GAAP operating income targets. The incentive amounts are calculated and paid
after the end of 2008. The amounts paid depend on the level of achievement against the objectives and, with respect
to the revenue and operating income objectives, range between zero and 200% of the target incentive. With respect
to the specified strategic goals, payments range between zero and 100% of the target incentive. However, no
payment is earned for any component if less than 80% of the operating income objective is achieved. At 80% of the
objective, 30% of the applicable component is earned; achievement of 100% of the objective results in 100% of the
component earned; and if 120% of the revenue or operating income objective is achieved, 200% of that component

30

is earned. At the time the Committee set the performance goals for the participants under the 2007 AIP, it believed
that they were achievable but only with significant effort.

Sign-on Incentive for Ms. Denholm

In connection with the hiring of Ms. Denholm in August 2007, the Committee approved the payment of a sign-
on incentive to Ms. Denholm of $250,000, which is subject to repayment on a prorated basis if she is terminated with
cause or voluntarily terminates her employment without good reason, each as defined in her offer letter, in the first
year of her employment. The Committee determined that such bonus was reasonable and necessary to secure the
services of Ms. Denholm in light of the expected incentive compensation from her prior employer that Ms. Denholm
had forgone in connection with joining Juniper Networks.

Long-Term Equity Incentive Compensation

Juniper Networks provides long-term equity incentive compensation through awards of stock options,
performance shares and restricted stock units. The Company’s equity compensation programs are intended to
align the interests of its employees with those of its stockholders by creating an incentive for our Section 16 officers
to drive financial performance over time and maximize stockholder value. The equity compensation program also is
designed to encourage our Section 16 officers to remain employed with the Company.

2007 Long-Term Incentive Program. For 2007, the Company reviewed its approach to equity awards and
decided to increase the focus on pay-for-performance by introducing performance shares into the mix of equity
awards, replacing the performance-awarded restricted stock unit grant opportunity provided to Section 16 officers
in 2006. The Company retained stock options as a key element of its equity compensation program.

The performance shares are earned based on performance against specific financial goals and then vest over
time. To the extent that specified performance goals are not met, shares are not earned. If an executive fails to satisfy
the service requirement, any earned shares are forfeited. The Committee believes that this combination of
performance and service requirements provides incentives to achieve both specified performance objectives
and increases in the Company’s stock price and also promotes retention.

For 2007, in determining the amount of long-term equity incentives to award each individual, the Committee
evaluated the value of the proposed long-term equity awards and total direct compensation and compared those
values to the market data discussed above. For 2007, to reflect the change in the Company’s size and maturity, the
Company’s objective was to move total direct compensation towards the 50th percentile of the market. However, in
making individual awards, the Committee took into account the individual executive’s performance, previously
granted awards, and in the case of executives other than the CEO, the CEO’s recommendations for award levels.

In structuring the 2007 awards, the Committee sought to allocate approximately 50% of the value to stock
options and 50% to performance shares. The Committee believed that the 50/50 split fairly balanced the need for
focus on long-term stockholder value creation and on intermediate financial performance objectives. Stock option
grants were valued using a risk-adjusted present value methodology, assuming an exercise price of $20.00 and
resulting in an estimated option value of $9.52 per share. Performance shares were valued assuming target
performance and at an assumed grant price of $20.00 per share.

The stock options were granted by the Company on March 9, 2007 and have an exercise price equal to the
closing market price on the date of grant of $18.31 per share. The options have a seven year term and vest with
respect to 25% of the shares on the first anniversary of grant and with respect to 1/48th of the shares each month
thereafter, assuming continued service to the Company.

The performance shares were granted on March 9, 2007 and vest based on achievement of specific
performance objectives established for each year of a three-year period. The amount of performance shares
earned for a particular year is based on the achievement of annual performance targets established for that year. For
2007 and 2008, the performance goals are based on revenue and non-GAAP operating margin. At the time the
Committee set the target performance goals, it believed that they were achievable but only with significant effort.
With respect to each year’s performance, the individual can earn between 0% and 200% of the target number of
shares for that year depending on the level of achievement against the goals established for that year. (The target

31

number of shares for each year is one third of the target number of shares for the entire three year period). Provided
the employee is still employed on the date that the Committee approves the performance calculation for the third
year, the employee is issued a number of fully paid and fully vested shares of common stock equal to the number
“earned” over the three year period.

For example: an employee is granted performance shares for a maximum of 60,000 shares with a target number
of 30,000 shares over a three year period. During the first year the Company achieves the target revenues and target
operating margin, and the employee earns the target number of 10,000 shares for that year, or 1/3 of the total target
number of shares for the full three year period. During the second year, the Company achieves target revenue but is
below target operating margin and the employee earns 5,000 shares. During the third year, the Company exceeds its
performance targets and the employee earns 20,000 shares. Accordingly, the employee is issued at the completion
of the three year cycle a total of 35,000 fully vested shares. No shares are vested or issued prior to the completion of
the third year, and any earned but unvested shares are forfeited if the employee leaves the Company before they are
vested and paid. The following table reflects the performance shares earned by our named executive officers under
the 2007 performance share award program for the awards granted on March 9, 2007:

2007 Restricted Stock Unit Awards (Based on 2006 Results). Prior to 2006, the Company relied primarily on
stock options to provide equity incentives to its Section 16 officers. In 2006, the Committee concluded that a
combination of both stock options and performance-awarded restricted stock units would better address the
Company’s compensation strategy, especially the need to balance incentives to drive performance with the need to
attract and retain executive talent.

In establishing the amount of long-term equity incentives to award each individual, the Committee evaluated
the total value of the proposed long-term equity awards and compared it to the competitive market data discussed
above. In 2006, the Company’s objective was to target long term equity incentive compensation at approximately
the 75th percentile of market data. In addition, the Committee also evaluated the retention value of prior equity
awards granted to an individual based on the potential value of the unvested portion of those awards under various
scenarios. In structuring the 2006 awards, the Committee sought to allocate 50% of the value to stock options and
50% to performance awarded restricted stock units. Performance awarded restricted stock grant guidelines were
created by applying a ratio of one share subject to a restricted stock unit being equivalent to 2.5 shares subject to a
stock option. This number was then increased by 20% to reflect the additional risk associated with the performance
feature discussed below.

The restricted stock units were awarded under a program pursuant to which the number of restricted stock units
issued to each officer was dependent on the achievement of earnings per share objectives for 2006. At the time the
Committee set the target performance goals for the participants under the 2006 restricted stock unit program, it
believed that they were achievable but only with significant effort. Depending on the level of performance against
the objectives, participants could receive restricted stock units for as much as 150% of the target number of

32

restricted stock units or as few as 25% of the target number of restricted stock units. The restricted stock units were
issued after the 2006 performance period vest as to 75% of the shares on February 27, 2008, 15% on February 27,
2009 and 10% on February 27, 2010.

The following table reflects the restricted stock units earned by our named executive officers under the 2006

restricted stock unit program and issued on February 27, 2007:

2007 Retention Equity Awards. On January 4, 2007, the Compensation Committee awarded restricted stock
units to Mr. Minshull and Ms. Perdikou in the amount of 120,000 and 80,000 shares respectively. Such restricted
stock units vest as to 25% of the shares on February 1, 2008, 25% on February 1, 2009 and 50% on February 1, 2010.
The recommendation for these awards was made by the Chief Executive Officer. In determining whether to provide
these awards and how many restricted stock units to award, the Compensation Committee considered several factors
including the expected value of the awards currently and under various stock price scenarios, whether existing
options were underwater, how critical are the contributions made by the individual, an assessment of retention risk
and the employee’s current target compensation before and after the award relative to market data and other
executive officers in the Company. These equity awards were intended to promote the retention of the individuals by
providing additional time-based equity awards.

2006 Promotion Equity Award Granted in 2007.

In May 2006, Ms. Perdikou was promoted from acting
General Manager to Executive Vice President Infrastructure Products Group and General Manager, Service
Provider Business Team. However, due to the stock option pricing investigation being conducted by the Company,
the Company did not grant her any stock options associated with that promotion until some time after the
completion of the investigation. Accordingly, Ms. Perdikou was granted an option to purchase 300,000 shares of our
common stock on February 27, 2007. The stock option award has an exercise price equal to the closing market price
on the date of grant of $18.53 per share. The option has a seven year term and vests with respect to 25% of the shares
on the first anniversary of grant and with respect to 1/48th of the shares each month thereafter, assuming continued
service to the Company.

2008 Long-Term Incentive Program. For 2008, the Company reviewed its approach to equity awards, and the
Committee decided to maintain the structure of long-term incentives similar to 2007 by providing a mix of stock
option and performance shares to Section 16 officers. Like the 2007 awards, the performance shares approved by
the Committee vest based on a combination of time and performance against specific objectives.

In determining the amount of long-term equity incentives to award each individual, the Committee evaluated
the value of the proposed long-term equity awards and total direct compensation and compared those values to the
competitive market data discussed above. For 2008, to reflect the growth in the Company’s size and maturity, and
based on the evaluation of its compensation practices relative to the Peer Group, the Company’s objective was to
continue to target total direct compensation near the 50th percentile of the Peer Group market data discussed above.
However, within this general objective, the specific number of equity awards for each of the Section 16 officers was
based on their respective roles and grade level. In structuring the 2008 awards, the Committee sought to allocate
50% of the value to stock options and 50% to the performance shares. Stock option grants were valued using a

33

Black-Scholes methodology, assuming an exercise price of $29.57 and resulting in an estimated option value of
$11.03 per share. Performance shares were valued assuming target performance and at an assumed grant price of
$29.57 per share for the purpose of establishing grant guidelines.

The stock options were granted by the Company on March 21, 2008 and have an exercise price equal to the
closing market price in effect on the date of grant of $25.16 per share. The options have a seven year term and vest
with respect to 25% of the shares on the first anniversary of grant and with respect to 1/48th of the shares each month
thereafter, assuming continued service to the Company.

The performance shares were granted on March 21, 2008 and vest at the end of three years based on
achievement of specific performance objectives established for each year of a three-year period. The amount of
performance shares earned for a particular year is based on the achievement of annual performance targets
established for that year. For 2008, the performance targets are based on revenue and non-GAAP operating margin.
At the time the Committee set the target performance goals, it believed that they were achievable but only with
significant effort. With respect to each year’s performance, the individual can earn between 0% and 200% of the
target amount for that year depending on the level of achievement against the targets established for that year (the
target amount for each year is one third of the target amount for the entire three year period). The terms of the 2008
performance shares are otherwise substantially identical to the 2007 performance shares discussed above.

Equity Ownership Guidelines. The Company believes that the significant component of each Section 16
officer’s overall compensation based on equity awards is sufficient to align the officer’s interests with those of the
stockholders. Moreover, the Company has also established limitations on the maximum amount of an officer’s stock
and option holdings that the officer can sell within any quarter or year without first obtaining the approval of the
Board of Directors. Accordingly, the Company has not adopted any specific requirements as to a minimum number
of shares that must be owned by an officer.

Stock Option Granting Policy.

In 2007, the Board of Directors approved a policy for granting stock options
and equity awards. New hire and ad hoc promotional and adjustment grants to non-executive employees are to be
granted monthly on the third Friday of the month, except as discussed below. If a quorum of the Stock Committee
(currently composed of the Chief Executive Officer, Chief Financial Officer and one outside director) is not
available for a meeting on or prior to the third Friday of the month or in the four days preceding it, grants are to be
approved by means of an action by written consent. Such consent shall by its terms provide that the options will be
granted upon the later of (i) the third Friday of the month or (ii) the date of the last signature of the Stock Committee
members. Annual performance grants to non-Section 16 officers will also be scheduled to occur on the same date as
a monthly grant and shall be approved by the Stock Committee in the manner described above. Grants in connection
with acquisitions shall, unless a date is specified in the acquisition agreement, occur to the extent practical on a date
on which equity awards to Company employees are made by the Stock Committee. Annual equity awards to
Section 16 officers will be generally scheduled to be approved at a meeting of the Compensation Committee in the
first quarter after the Q4 earnings announcement and prior to March 1. The annual grants to Section 16 persons are
also generally scheduled to be effective on the third Friday of the month if the meeting approving such grants occurs
on or before such date. Notwithstanding the foregoing, if the Company is advised by outside counsel that the
granting of equity awards on a particular date or to particular recipients, or prior to the disclosure of certain non-
public information, could reasonably be deemed to be a violation of applicable laws or regulations, such grants may
be delayed until such time as the granting of those awards would be not reasonably expected to constitute a
violation. If doing a particular monthly grant would cause the Company to exceed any granting limitation imposed
by the Board or Compensation Committee (such as an annual limit), the monthly grant shall be delayed until the first
subsequent month in which the limitation would not be exceeded. If the making of a grant would cause the
Company to violate the terms of any agreement approved by the Board or a Committee of the Board, such grant
shall be delayed until it would not be in violation of such agreement. The exercise price of options granted will be
the closing market price on the effective date of grant. The Company intends to grant options in accordance with the
foregoing policy without regard to the timing of the release of material non-public information, such as a positive or
negative earnings announcement.

Deferred Compensation Program.

In addition to the long term incentive programs described above, the
Company plans to adopt and implement a deferred compensation program for certain grade levels of Company

34

management, including Section 16 officers, beginning in June 2008. The Company plans to implement this program
in order to offer benefits that are competitive with companies with which it competes for talent. This program, once
implemented, would allow participants to elect to defer a certain amount of compensation earned into one or more
investment choices. The participants would not be taxed on the compensation deferred into these investments until
distribution of invested funds to the participant at a future date, which may be upon termination of employment with
the Company or a designated “in-service” date elected by the participant.

Employee Benefits and Perquisites

Historically, the Company has made available to Section 16 officers the same employee benefits and
perquisites that are available to employees broadly. The Company provides employee benefit programs and
perquisites to employees, including Section 16 officers, that the Company and the Committee believe are
reasonable and consistent with its overall compensation program to better enable the Company to attract and
retain employees. Except for the Deferred Compensation Program described above and the Executive Wellness
Program described below, there are no other special benefit plans or programs applicable to Section 16 officers.
Accordingly, employee benefits and perquisites are reviewed from time to time generally to ensure that benefit
levels remain competitive but are generally not included in the Committee’s annual determination of a Section 16
officer’s compensation package.

Section 16 officers are entitled to participate on the same basis and in the same medical, dental, vision,
disability, life insurance and other plans and programs made available to other full time employees in the applicable
country of residence. In addition, the Committee approved the adoption of an Executive Wellness Program (the
“Wellness Program”) beginning in June 2008. Under the Wellness Program, eligible executives, including
Section 16 officers, will receive additional benefits focused on health care screening and wellness. The total
value this benefit is limited to $10,000 per year for each eligible executive. The Committee believes that by
promoting the health and wellness of its executives can result in a number of benefits to the Company, including
increased productivity, better presenteeism and increased organizational stability, among others.

The Company has a 401(k) tax-qualified retirement savings plan pursuant to which all U.S. based employees
are entitled to participate. Employees can make contributions to the plan on a before-tax basis to the maximum
amount prescribed by the Internal Revenue Service. The Company will match 25% of the amount contributed by the
employee. The Company matching contributions are fully-vested upon contribution. Mr. Minshull participates in
the Group Personal Pension Plan which is a tax-qualified defined contribution retirement plan available to all full
time employees in the United Kingdom. The Company contributes 7% of an employee’s base salary to the plan
following an initial period of service, which Mr. Minshull has satisfied. As such, Company contributions for
Mr. Minshull are fully-vested upon contribution. The Company does not match employee contributions to this plan.
Other than these generally available plans, there are no other deferred savings plans in which the Section 16 officers
currently participate. The Company does not maintain or provide any defined benefit plans for its employees.

As is typical for the Company’s managers in Europe, Mr. Minshull is given a car allowance. Mr. Minshull
receives a car allowance of $2,424 per month in arrears, less deductions for tax and U.K. National Insurance taxes
contributions. He is also entitled to reimbursement of fuel costs through the standard expense reimbursement
process.

From time to time, the Company may agree to reimburse employees for relocation costs if the employee’s job
responsibilities require him or her to move a significant distance. In connection with Mr. Elop’s joining the
Company in January 2007, the Company agreed to reimburse Mr. Elop for relocation expenses to facilitate his move
to a location near the Company’s corporate headquarters. Mr. Elop was reimbursed $19,843 in connection with such
expenses.

Attributed costs of the personal benefits described above for the named executive officers for the fiscal year
ended December 31, 2007, are included in the column entitled “All Other Compensation” in the Summary
Compensation Table on page 40.

Severance Benefits

In addition to compensation designed to reward employees for service and performance, the Company has
approved certain severance and change of control provisions for certain employees, including named executive
officers.

Basic Severance.

In order to recruit executives to the Company and encourage retention of employees, the
Company believes it is appropriate and necessary to provide assurance of certain severance payments if the
Company terminates the individual’s employment without cause, as described below. On January 4, 2007, the
Committee approved severance benefits for several members of senior management, including Mr. Kriens,
Mr. Elop, Mr. Minshull and Ms. Perdikou. In the event the employee is terminated involuntarily by Juniper
Networks without cause, as defined in the agreement, and provided the employee executes a full release of claims,
in a form satisfactory to Juniper Networks, promptly following termination, the employee will be entitled to receive
the following severance benefits: (i) an amount equal to six months of base salary and (ii) an amount equal to half of
the individual’s annual target bonus for the fiscal year in which the termination occurs. Upon the commencement of
her employment in August 2007, Ms. Denholm entered into a severance agreement with the Company that provided
the aforementioned benefits upon substantially similar terms as the other named executive officers plus six months
of Company-paid health, dental and vision insurance coverage. In addition, Ms. Denholm’s severance agreement
provides that in the event Ms. Denholm voluntarily terminates her employment with the Company within the first
two (2) years of employment for good reason, as defined in the agreement, and provided she executes a full release
of claims, promptly following termination Ms. Denholm shall receive the following severance benefits: (i) an
amount equal to six months of base salary, (ii) an amount equal to half of her annual target bonus for the fiscal year
in which the termination occurs, (iii) six months of Company-paid health, dental and vision insurance coverage,
(iv) provided no shares have otherwise vested under the restricted stock unit award granted to Ms. Denholm in
August 2007, acceleration of vesting of such restricted stock units equal to the total number of shares covered by
such award, multiplied by the number of full months of service to the Company completed through the date of
termination divided by 48, and (v) provided no shares have otherwise vested under the above stock option award
granted to Ms. Denholm in August 2007, acceleration of vesting of such options equal to the total number of shares
covered by such award, multiplied by the number of full months of service to the Company completed through the
date of termination divided by 48. The Company believes that the size of the severance packages described is
consistent with severance offered by other companies of the Company’s size or in the Company’s industry.

The Company had also entered into an agreement with Mr. Dykes on December 13, 2004, which provides that
if Mr. Dykes is terminated involuntarily by the Company without cause, as defined in the agreement, promptly
following termination Mr. Dykes will be entitled to receive the following severance benefits: (i) an amount equal to
six months of his base salary, (ii) an amount equal to half of his annual at target bonus for the fiscal year in which
termination occurs and (iii) and acceleration of six months of vesting of his initial grant of options to purchase
shares of the Company’s common stock. Mr. Dykes was provided the benefits described above after his employment
terminated.

36

The following table describes the potential payments upon termination of employment without cause
(assuming the change in control benefits discussed below do not apply) for each of the named executive officers
as described above. Amounts payable is cash assume relevant salary, bonus and benefit values in effect as of
December 31, 2007. The amounts in the following table for equity awards for Ms. Denholm represent the additional
value of the awards that vest as a result of the resignation for good reason (as defined in the applicable agreement).
For purposes of valuing the equity awards, the amounts below are based on a per share price of $33.20, which was
the closing price as reported on the Nasdaq Global Select Market on December 31, 2007. The amounts in the
following table related to benefits represent the amounts payable by the Company to maintain Ms. Denholm’s
benefits for the period following termination of employment as described above.

Change in Control Severance. The Committee considers maintaining a stable and effective management
team to be essential to protecting and enhancing the best interests of Juniper Networks and its stockholders. To that
end, Juniper Networks recognizes that the possibility of a change in control may exist from time to time, and that
this possibility, and the uncertainty and questions it may raise among management, may result in the departure or
distraction of management to the detriment of the Company and its stockholders. Accordingly, the Committee
decided to take appropriate steps to encourage the continued attention, dedication and continuity of members of the
Company’s management to their assigned duties without the distraction that may arise from the possibility of a
change in control. As a result, the Committee approved certain severance benefits for Mr. Kriens, Ms. Denholm,
Mr. Dykes, Mr. Elop, Mr. Minshull and Ms. Perdikou, as well as for several members of senior management, in the
event of a change in control. In approving these benefits the committee considered a number of factors, including
the prevalence of similar benefits adopted by other publicly traded companies.

Under the benefits approved by the Committee, provided the employee signs a release of claims and complies
with certain post termination non-solicitation and non-competition obligations, the employee will receive change in
control severance benefits if either (i) the employee is terminated without cause within 12 months following the
change in control or (ii) between 4 and 12 months following a change in control the employee terminates his or her
employment with the Company (or any parent or subsidiary of the Company) for good reason” (both “cause” and
“good reason” are defined in the agreement). For the purposes of this agreement, a reduction in duties, title,
authority or responsibilities solely by virtue of the Company being acquired and made part of a larger entity (as, for
example, when the Chief Financial Officer of the Company remains the Chief Financial Officer of the subsidiary or
business unit substantially containing the Company’s business following a change of control) does not by itself
constitute grounds for “good reason”.

The change in control severance benefits consist of: (i) a cash payment equal to the employee’s annual base
salary plus the employee’s target bonus for the fiscal year in which the change of control or the employee’s
termination occurs, whichever is greater, (ii) acceleration of vesting of all of the employee’s then unvested
outstanding stock options, stock appreciation rights, restricted stock units and other Company equity compensation
awards, and (iii) one year of Company-paid health, dental and vision insurance coverage.

change in control of Juniper Networks for each of the named executive officers. The amounts in the following table
for equity awards represent the value of the awards that vest as a result of the termination without cause or a
resignation for “good reason” (as defined in the applicable agreement) of the named executive officer’s employment
in connection with a change in control. For purposes of valuing the stock options, the amounts below are based on a
per share price of $33.20, which was the closing price as reported on the Nasdaq Global Select Market on
December 31, 2007. Other amounts payable assume relevant salary, bonus and benefit values in effect as of
December 31, 2007. The amounts in the following table related to benefits represent the amounts payable by the
Company to maintain the officer’s benefits for the period following the termination of the named executive officer’s
employment in connection with a change in control as described above.

Amendment of Certain Stock Options

On May 1, 2007, the Company increased the exercise price of certain unexercised stock options held by
Ms. Perdikou that had original exercise prices per share that were less than the fair market value per share of the
Company’s common stock on the option’s date of grant, as determined by the Company for financial accounting
purposes in connection with its investigation into historical stock option practices. The options were amended to
increase the exercise price for the unexercised portion of these affected options to the appropriate fair market value
per share on the date of grant. The purpose of these amendments was to avoid unfavorable tax consequences for
Ms. Perdikou under United States Internal Revenue Code Section 409A (“Section 409A”) which would result upon
the vesting of options that have an exercise price that is less than fair market value of the underlying common stock
on the option’s date of grant. All options covered by these amendments were granted to Ms. Perdikou prior to the
dates upon which she was promoted to her role as a Section 16 officer. In exchange for Ms. Perdikou agreeing to
increase the exercise price of these options, the Company agreed make a cash payment to Ms. Perdikou of
$61,391.63 (less any applicable tax withholdings), an amount equal to the to the incremental per share exercise price
increase multiplied by the corresponding number of shares subject to the affected options. In order to satisfy the
provisions of Section 409A, this payment was made in January 2008.

The Impact of Favorable Accounting and Tax Treatment on Compensation Program Design

Favorable accounting and tax treatment of the various elements of our compensation program is a relevant
consideration in their design. However, the Company and Committee have placed a higher priority on structuring
flexible compensation programs to promote the recruitment, retention and performance of Section 16 officers than
on maximizing tax deducibility. Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Tax
Code”), places a limit of $1,000,000 on the amount of compensation that Juniper Networks may deduct in any one
year with respect to each of its five most highly paid executive officers. To maintain flexibility in compensating
executive officers in a manner designed to promote varying corporate goals, the Committee has not adopted a policy
requiring all compensation to be deductible.

38

There is an exception to the $1,000,000 limitation for certain performance-based compensation meeting
certain requirements. The Company believes that the stock options and performance shares awarded under the
Company’s 2006 Equity Incentive Plan will meet the terms of the exception. Restricted stock units are not
considered performance-based under Section 162(m) of the Tax Code and, as such, are generally not deductible by
the Company. The Company has not sought stockholder approval of its annual cash incentive plans, and therefore,
payments under those plans may not be fully deductible.

Beginning on January 1, 2006, the Company began accounting for stock-based payments including its Stock
Option Program, Long-Term Stock Grant Program, Restricted Stock Program and Stock Award Program in
accordance with the requirements of FASB Statement 123(R). Like many of the companies within our Peer Group,
Juniper Networks has lowered both grant guidelines and option participation rates to ensure that the Company’s
equity granting practice remains competitive but also within acceptable cost limitations.

(1) Amounts shown do not reflect compensation actually received by the named executive officer. Instead, the
amounts shown are the compensation costs recognized by Juniper Networks in fiscal 2007 or fiscal 2006, as
applicable for equity awards as determined pursuant to FAS 123R disregarding forfeiture assumptions. These
compensation costs reflect option awards granted in and prior to fiscal 2007 or fiscal 2006, as applicable, as
well as restricted stock unit awards earned in 2006 but issued in 2007 as described in “Compensation
Discussion and Analysis” above. The assumptions used to calculate the value of option awards are set forth
under Note 1 of the Notes to Consolidated Financial Statements included in Juniper Networks Annual Report
on Form 10-K for 2007 filed with the SEC on February 29, 2008.

(2) Amounts reflect bonuses earned in 2007 but paid in 2008 under the 2007 Juniper Networks Annual Incentive

Plan.

(3) Amounts reflect bonuses earned in 2006 but paid in 2007 under the 2006 Juniper Networks Executive Officer

Bonus Plan.

(4) Consists of costs related to the standard employee benefit portion paid by the Company for life and disability

insurance premiums and $5,125 in matching contributions paid under the Company’s 401(k) plan.

(5) Consists of costs related to the standard employee benefit portion paid by the Company for life and disability

insurance premiums and $2,000 in matching contributions paid under the Company’s 401(k) plan.

(6) Amount paid reflects a $250,000 sign on bonus paid to Ms. Denholm upon commencement of employment

with the Company.

40

(7) Consists of costs related to the standard employee benefit portion paid by the Company for life and disability

insurance premiums and $2,500 in matching contributions paid under the Company’s 401(k) plan.

(8) On January 4, 2007, the Compensation Committee approved discretionary cash bonuses for 2006 for
Mr. Minshull, Ms. Perdikou and Mr. Dykes in the amounts of $250,000, $125,000 and $125,000, respectively.
In determining the amount these bonuses, the Committee considered the additional responsibilities and
projects assumed by the individuals, their performance in their roles, and their overall cash compensation.
These amounts were in addition to incentives paid pursuant to the 2006 Executive Incentive Plan which
provides variable compensation based primarily on financial performance. Based on the leadership and
performance demonstrated in 2006 in new roles assumed by the individuals or in managing additional projects
and responsibilities undertaken during the year, it was determined that discretionary bonuses be awarded to
these individuals in recognition of those contributions in addition to amounts earned based on financial
performance. In addition, in May 2006, Ms. Perdikou was promoted from acting General Manager to
Executive Vice President Infrastructure Products Group and General Manager, Service Provider Business
Team. However, due to the stock option pricing investigation being conducted by the Company, the Company
did not grant her any stock options associated with that promotion until some time after the completion of the
investigation. In recognition of Ms. Perdikou’s service in the role for seven months without having received
any equity awards in connection with this promotion, the Company approved in December 2006 a special cash
bonus of $175,000.

(9) Consists of a severance payment of $400,000, $34,028 payment of paid time off accrual upon Mr. Dykes
resignation from the Company, $1,000 related to a patent filing under a program generally available to all
employees, $5,125 in matching contributions paid under the company’s 401(k) plan; and $1,122 in costs
related to the standard employee benefit portion paid by the Company for life and disability insurance
premiums.

(10) Consists of costs related to the standard employee benefit portion paid by the Company for life and disability
insurance premiums, $19,843 in reimbursed relocation expenses, $3,875 in matching contributions paid under
the Company’s 401(k) plan and a $374 gift received under an internal award program.

(11) Mr. Minshull is paid in British Pounds (£). The 2006 and 2007 compensation amounts for Mr. Minshull in this
proxy statement are presented on an as-converted to U.S. Dollars ($) basis at a rate of $1.9515 and $2.02 for
each £1, respectively. This represents the exchange rate in effect for conversion of British Pounds to U.S.
Dollars as of December 31, 2006 and December 31, 2007, respectively.

(12) Amounts paid reflect $29,088 in car allowance and $32,522 in contributions paid by Juniper Networks under
the Company’s UK Group Personal Pension Plan, a defined contribution plan available to all full-time UK
employees.

(13) Amount reflects $115,305 in commissions paid; $28,102 in car allowance and $30,855 in matching con-
tributions paid under the Company’s UK Group Personal Pension Plan, a defined contribution plan available to
all full-time UK employees.

(14) Amount reflects incremental increase in fair value related to the stock option exercise price adjustment for Ms.
Perdikou on May 1, 2007 as described in Compensation Discussion and Analysis. Because the applicable
exercise prices were increased, there was no incremental increase in such fair value.

(15) Amount reflects $61,392 paid in January 2008 in relation to the stock option exercise price adjustment for
Ms. Perdikou on May 1, 2007, costs related to the standard employee benefit portion paid by the Company for
life and disability insurance premiums and $1,258 in matching contributions paid under the Company’s 401(k)
plan.

(1) The option was granted on 1/29/2004. The shares became exercisable as to 25% of the shares on 1/29/2005 and
vest monthly thereafter to be fully vested on 1/29/2008, assuming continued employment with Juniper
Networks.

(2) The option was granted on 4/29/2005. The shares became exercisable as to 25% of the shares on 1/1/2006 and
vest monthly thereafter to be fully vested on 1/1/2009 assuming continued employment with Juniper
Networks.

(3) The option was granted on 4/29/2005. The shares became exercisable as to one-forty-eighth of the shares on
1/1/2006 and vest monthly thereafter to be fully vested on 1/1/2010 assuming continued employment with
Juniper Networks.

(4) The option was granted on 2/8/2006. The shares became exercisable as to 25% of the shares on 2/8/2007 and
vest monthly thereafter to be fully vested on 2/8/2010 assuming continued employment with Juniper
Networks.

(5) The option was granted on 3/9/2007. The shares became exercisable as to 25% of the shares on 3/9/2008 and
vest monthly thereafter to be fully vested on 3/9/2011 assuming continued employment with Juniper
Networks.

(6) The option was granted on 8/14/2007. The shares become exercisable as to 25% of the shares on 8/14/2008
and vest monthly thereafter to be fully vested on 08/14/2011 assuming continued employment with Juniper
Networks.

(7) The option was granted on 9/17/2004. The shares became exercisable as to 25% of the shares on 9/17/2005 and
vested monthly thereafter. On December 16, 2005, the Board approved the acceleration of the vesting of
certain unvested and “out-of-the-money” stock options that had an exercise price per share equal to or greater
than $22.00, all of which were previously granted under its stock option plans and that were outstanding on
December 16, 2005, including this option held by Ms. Perdikou. Options accelerated excluded options
previously granted to certain employees, including all of the Company’s executive officers and its directors.
However, the acceleration occurred before Ms. Perdikou had been promoted to her role as an executive officer
of the Company. The acceleration of the unvested and “out-of-the-money” options was accompanied by
restrictions imposed on any shares purchased through the exercise of accelerated options. Those restrictions
will prevent the sale of any such shares prior to the date such shares would have originally vested had the
optionee been employed on such date, whether or not the optionee is actually an employee at that time.

(8) The option was granted on 2/8/2006. 7,292 of the shares became exercisable as on 2/8/2006 and vest monthly
thereafter to be fully vested on 04/01/2009 assuming continued employment with Juniper Networks.

(9) The option was granted on 2/27/2007. The shares became exercisable as to 25% of the shares on 2/27/2008 and
vest monthly thereafter to be fully vested on 2/27/2011 assuming continued employment with Juniper
Networks.

(10) The option was granted on 1/08/2007. The shares became exercisable as to 25% of the shares on 1/8/2008 and

vest monthly thereafter to be fully vested on 1/8/2011.

(11) Represents maximum shares issuable under performance share awards granted in 2007.

(12) The market value of the Stock Awards made is based on the closing market price of our common stock as of

December 31, 2007, which was $33.20.

awards as of May 18, 2006 were canceled on May 18, 2006. The 1996 Plan will remain in effect as to
outstanding equity awards granted under the plan prior to May 18, 2006.

(2) Includes the 2000 Nonstatutory Stock Option Plan (the “2000 Plan”). No options were issued under this Plan to
any directors or persons serving as executive officers at the time of grant. Effective May 18, 2006, additional
equity awards under the 2000 Plan have been discontinued and new equity awards are being granted under the
2006 Plan. Remaining authorized shares under the 2000 Plan that were not subject to outstanding awards as of
May 18, 2006 were canceled on May 18, 2006. The 2000 Plan will remain in effect as to outstanding equity
awards granted under the plan prior to May 18, 2006.

(3) Excludes 6,289,843 shares subject to restricted stock units and performance share awards outstanding as of

December 31, 2007 that were issued under the 1996 Plan and 2006 Plan.

(4) Excludes purchase rights accruing under the 1999 Purchase Plan, which had a remaining stockholder-approved
reserve of 10,894,510 shares as of December 31, 2007. As of March 1, 2008, the remaining stockholder-
approved reserve under the 1999 Purchase Plan was 13,149,032 shares. If the 2008 Employee Stock Purchase
Plan (the “2008 ESPP”) is approved on the terms set forth in this proxy statement, the 1999 Purchase Plan will
be terminated immediately following the conclusion of the offering period ending January 30, 2009, and the
remaining shares reserved for issuance thereunder would no longer be available for issuance.

(5) Consists of shares available for future issuance under the 2006 Plan and the 1999 Purchase Plan. As of
December 31, 2007, an aggregate of 46,005,450 and 10,894,510 shares of Common Stock were available for
issuance under the 2006 Plan and the 1999 Purchase Plan, respectively. Under the terms of the 2006 Plan, any
shares subject to any options under the Company’s 2000 Plan and 1996 Plan that are outstanding on May 18,
2006 and that subsequently expire unexercised, up to a maximum of an additional 75,000,000 shares will
become available for issuance under the 2006 Plan. Under the terms of the 1999 Purchase Plan, an annual
increase is added on the first day of each fiscal year equal to the lesser of (a) 3,000,000 shares, (b) 1% of the
Company’s outstanding shares on that date or (c) a lesser amount determined by the Board of Directors. The
Board has reserved 12,000,000 shares of Common Stock for issuance under the 2008 ESPP and, in contrast to
the 1999 Purchase Plan, which had automatic annual increases to the shares reserved under such plan, no further
increases can be made to the shares reserved for issuance under the 2008 ESPP without the approval of the
Company’s stockholders.

45

(6) As of December 31, 2007, a total of 3,680,430 shares of the Company’s Common Stock were issuable upon
exercise of outstanding options under plans assumed in connection with acquisitions. The weighted average
exercise price of those outstanding options is $11.60 per share. No additional options may be granted under
those assumed plans.

Appendix A

JUNIPER NETWORKS, INC.

2008 EMPLOYEE STOCK PURCHASE PLAN

1. Purpose. The purpose of the Plan is to provide employees of the Company and its Designated Subsid-
iaries with an opportunity to purchase Common Stock through accumulated payroll deductions. The Company’s
intention is to have the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code (the
“423(b) Plan”), although the Company makes no undertaking nor representation to maintain such qualification. The
provisions of the 423(b) Plan, accordingly, will be construed so as to extend and limit Plan participation in a uniform
and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. In addition, this Plan
document authorizes the grant of rights to purchase stock that do not qualify under Section 423(b) of the Code
(“Non-Section 423(b) Plan”) pursuant to rules, procedures or sub-plans adopted by the Board or Committee
designed to achieve tax, securities law or other Company compliance objectives in particular locations outside the
United States. Such references to the Plan include the 423(b) and the Non-Section 423(b) Plan components.

If grants are intended to be made under the Non-Section 423(b) Plan, they will be designated as such at the time

of grant.

4. Offering Periods. The Plan will be implemented by consecutive Offering Periods with a new Offering
Period commencing on the first Trading Day on or after February 1 and August 1 each year, or on such other date as

Company’s payroll office (or its designee), on or before a date prescribed by the Administrator prior to an applicable

A-3

6. Payroll Deductions.

(a) At the time a participant enrolls in the Plan pursuant to Section 5, he or she will elect to have payroll
deductions made on each pay day during the Offering Period in an amount not exceeding ten percent (10%) of the
Compensation which he or she receives on each pay day during the Offering Period. The Administrator, in its
discretion, may decide that an Employee may submit contributions to the Non-Section 423(b) Plan by means other
than payroll deductions. A participant’s subscription agreement will remain in effect for successive Offering
Periods unless terminated as provided in Section 10 hereof.

(b) Payroll deductions for a participant will commence on the first pay day following the Offering Date and
will end on the last pay day prior to the Exercise Date of such Offering Period to which such authorization is
applicable, unless sooner terminated by the participant as provided in Section 10 hereof.

(c) All payroll deductions made for a participant will be credited to his or her account under the Plan and will
be withheld in whole percentages only. A participant may not make any additional payments into such account.

(d) A participant may discontinue his or her participation in the Plan as provided in Section 10, or may
decrease the rate of his or her payroll deductions during the Offering Period by (i) properly completing and
submitting to the Company’s payroll office (or its designee), on or before a date prescribed by the Administrator
prior to an applicable Exercise Date, a new subscription agreement authorizing the change in payroll deduction rate
in the form provided by the Administrator for such purpose, or (ii) following an electronic or other procedure
prescribed by the Administrator. If a participant has not followed such procedures to change the rate of payroll
deductions, the rate of his or her payroll deductions will continue at the originally elected rate throughout the
Offering Period and future Offering Periods (unless terminated as provided in Section 10). The Administrator may,
in its sole discretion, limit the nature and/or number of payroll deduction rate changes that may be made by
participants during any Offering Period. Any change in payroll deduction rate made pursuant to this Section 6(d)
will be effective as of the first full payroll period following five (5) business days after the date on which the change
is made by the participant.

(e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and
Section 3(b), a participant’s payroll deductions may be decreased to zero percent (0%) at any time during an
Offering Period. Subject to Section 423(b)(8) of the Code and Section 3(b) hereof, payroll deductions will
recommence at the rate originally elected by the participant effective as of the beginning of the first Offering Period
which is scheduled to end in the following calendar year, unless terminated by the participant as provided in
Section 10.

(f) At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock
issued under the Plan is disposed of, the participant must make adequate provision for the Company’s or Employer’s
federal, state, or any other tax withholding liability payable to any authority, national insurance, social security or
other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the
Common Stock. At any time, the Company or the Employer may, but will not be obligated to, withhold from the
participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding
obligations, including any withholding required to make available to the Company or the Employer any tax
deductions or benefits attributable to the sale or early disposition of Common Stock by the Employee.

7. Grant of Option. On the Offering Date of each Offering Period, each Employee participating in such
Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Employee’s
payroll deductions accumulated prior to such Exercise Date and retained in the Employee’s account as of the
Exercise Date by the applicable Purchase Price; provided that in no event will an Employee be permitted to
purchase during any twelve (12) month period more than six thousand (6,000) shares of the Common Stock (subject
to any adjustment pursuant to Section 19), and provided further that such purchase will be subject to the limitations
set forth in Sections 3(b) and 13. The Employee may accept the grant of such option with respect to any Offering
Period under the Plan, by electing to participate in the Plan in accordance with the requirements of Section 5. The
Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum
number of shares of Common Stock that each Employee may purchase during each Offering Period. Exercise of the

A-4

option will occur as provided in Section 8, unless the participant has withdrawn pursuant to Section 10. The option
will expire on the last day of the Offering Period.

8. Exercise of Option.

(a) Unless a participant withdraws from the Plan as provided in Section 10, his or her option for the purchase
of shares of Common Stock will be exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option will be purchased for such participant at the applicable Purchase Price with the accumulated
payroll deductions in his or her account. No fractional shares of Common Stock will be purchased; any payroll
deductions accumulated in a participant’s account which are not sufficient to purchase a full share will be retained in
the participant’s account for the subsequent Offering Period, subject to earlier withdrawal by the participant as
provided in Section 10. Any other funds left over in a participant’s account after the Exercise Date will be returned
to the participant. During a participant’s lifetime, a participant’s option to purchase shares hereunder is exercisable
only by him or her.

(b) If the Administrator determines that, on a given Exercise Date, the number of shares of Common Stock
with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were
available for sale under the Plan on the Offering Date of the applicable Offering Period, or (ii) the number of shares
of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole
discretion provide that the Company will make a pro rata allocation of the shares of Common Stock available for
purchase on such Offering Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as
it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common
Stock on such Exercise Date, and continue all Offering Periods then in effect or terminate all Offering Periods then
in effect pursuant to Section 20. The Company may make a pro rata allocation of the shares available on the Offering
Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of
additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Offering Date.

9. Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares of
Common Stock occurs, the Company will arrange the delivery to each participant the shares purchased upon
exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules
established by the Administrator. No participant will have any voting, dividend, or other stockholder rights with
respect to shares of Common Stock subject to any option granted under the Plan until such shares have been
purchased and delivered to the participant as provided in this Section 9.

10. Withdrawal.

(a) A participant may withdraw all but not less than all the payroll deductions credited to his or her account
and not yet used to exercise his or her option under the Plan at any time by (i) submitting to the Company’s payroll
office (or its designee) a written notice of withdrawal in the form prescribed by the Administrator for such purpose
(which may be similar to the form attached hereto as Exhibit B), or (ii) following an electronic or other withdrawal
procedure prescribed by the Administrator. All of the participant’s payroll deductions credited to his or her account
will be paid to such participant promptly after receipt of notice of withdrawal and such participant’s option for the
Offering Period will be automatically terminated, and no further payroll deductions for the purchase of shares will
be made for such Offering Period. If a participant withdraws from an Offering Period, payroll deductions will not
resume at the beginning of the succeeding Offering Period, unless the participant re-enrolls in the Plan in
accordance with the provisions of Section 5.

(b) A participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to
participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the participant withdraws.

11. Termination of Employment. Upon a participant’s ceasing to be an Eligible Employee, for any reason, he
or she will be deemed to have elected to withdraw from the Plan and the payroll deductions credited to such
participant’s account during the Offering Period but not yet used to purchase shares of Common Stock under the
Plan will be returned to such participant or, in the case of his or her death, to the person or persons entitled thereto
under Section 15, and such participant’s option will be automatically terminated.

A-5

12. Interest. No interest will accrue on the payroll deductions of a participant in the Plan.

13. Stock.

(a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the
maximum number of shares of Common Stock which will be made available for sale under the Plan will be twelve
million (12,000,000) shares.

(b) Until the shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company), a participant will only have the rights of an unsecured creditor with
respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with
respect to such shares.

(c) Shares of Common Stock to be delivered to a participant under the Plan will be registered in the name of

the participant or, at the sole discretion of the Company, in the name of the participant and his or her spouse.

14. Administration. The Plan will be administered by the Board or a Committee appointed by the Board,
which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and
exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and
to adjudicate all disputed claims filed under the Plan. Every finding, decision and determination made by the
Administrator will, to the full extent permitted by law, be final and binding upon all parties. Notwithstanding any
provision to the contrary in this Plan, and, with respect to the Section 423(b) Plan, to the extent permissible under
Code Section 423 and proposed or final Treasury Regulations promulgated thereunder (and other Internal Revenue
Service guidance), the Administrator may adopt rules or procedures relating to the operation and administration of
the Plan to accommodate the specific requirements of local laws and procedures for jurisdictions outside of the
United States. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt
rules and procedures regarding handling payroll deductions, making of contributions to the Plan, defining eligible
Compensation, establishment of bank or trust accounts to hold payroll deductions, conversion of local currency,
obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and
handling of stock certificates which vary with local requirements.

The Administrator may also adopt rules, procedures or sub-plans applicable to particular Subsidiaries or
locations, which sub-plans may be designed to be outside the scope of Code Section 423. The rules of such sub-
plans may take precedence over other provisions of this Plan, but unless otherwise superseded by the terms of such
sub-plan, the provisions of this Plan shall govern the operation of such sub-plan. To the extent inconsistent with the
requirements of Section 423, such sub-plan shall be considered part of the Non-Section 423(b) Plan, and rights
granted thereunder shall not be considered to comply with Code Section 423.

15. Designation of Beneficiary.

(a) At the sole discretion of the Administrator, a participant may file a designation of a beneficiary who is to
receive any shares of Common Stock and cash, if any, from the participant’s account under the Plan in the event of
such participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such
participant of such shares and cash. In addition, a participant may file a designation of a beneficiary who is to
receive any cash from the participant’s account under the Plan in the event of such participant’s death prior to
exercise of the option. If a participant is married and the designated beneficiary is not the spouse, spousal consent
will be required for such designation to be effective.

(b) Such designation of beneficiary may be changed by the participant at any time by notice in a form
determined by the Administrator. In the event of the death of a participant and in the absence of a beneficiary validly
designated under the Plan who is living at the time of such participant’s death, the Company will deliver such shares
and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator
has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares
and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent
or relative is known to the Company, then to such other person as the Company may designate.

(c) All beneficiary designations will be in such form and manner as the Administrator may designate from

time to time.

A-6

16. Transferability. Neither payroll deductions credited to a participant’s account nor any rights with regard
to the exercise of an option or to receive shares of Common Stock under the Plan may be assigned, transferred,
pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided
in Section 15 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition will be
without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period
in accordance with Section 10 hereof.

17. Use of Funds. The Company may use all payroll deductions received or held by it under the Plan for any
corporate purpose, and the Company will not be obligated to segregate such payroll deductions. Until shares of
Common Stock are issued, participants will only have the rights of an unsecured creditor with respect to such
shares.

18. Reports.

Individual accounts will be maintained for each participant in the Plan. Statements of account
will be given to participating Employees at least annually, which statements will set forth the amounts of payroll
deductions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance,
if any.

19. Adjustments, Dissolution, Liquidation, Merger or Change in Control.

(a) Adjustments.

In the event that any dividend or other distribution (whether in the form of cash, Common
Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the
Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the
Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made
available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common
Stock which may be delivered under the Plan, the Purchase Price per share and the number of shares of Common
Stock covered by each option under the Plan which has not yet been exercised, and the numerical limits of Sections 7
and 13.

(b) Dissolution or Liquidation.

In the event of the proposed dissolution or liquidation of the Company, any
Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately
prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Admin-
istrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The
Administrator will notify each participant in writing, at least ten (10) business days prior to the New Exercise Date,
that the Exercise Date for the participant’s option has been changed to the New Exercise Date and that the
participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the
participant has withdrawn from the Offering Period as provided in Section 10 hereof.

(c) Merger or Change in Control.

In the event of a merger or Change in Control, each outstanding option
will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, the
Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date and will
end on the New Exercise Date. The New Exercise Date will occur before the date of the Company’s proposed
merger or Change in Control. The Administrator will notify each participant in writing, at least ten (10) business
days prior to the New Exercise Date, that the Exercise Date for the participant’s option has been changed to the New
Exercise Date and that the participant’s option will be exercised automatically on the New Exercise Date, unless
prior to such date the participant has withdrawn from the Offering Period as provided in Section 10 hereof.

20. Amendment or Termination.

(a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at
any time and for any reason; provided, however, that adding additional shares available for sale under the Plan
(other than pursuant to Section 19(a)) shall require stockholder approval. If the Plan is terminated, the Admin-
istrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon
completion of the purchase of shares of Common Stock on the next Exercise Date (which may be sooner than
originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to
expire in accordance with their terms (and subject to any adjustment pursuant to Section 19). If the Offering Periods

A-7

are terminated prior to expiration, all amounts then credited to participants’ accounts which have not been used to
purchase shares of Common Stock will be returned to the participants (without interest thereon, except as otherwise
required under local laws) as soon as administratively practicable.

(b) Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to
change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an
Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars,
permit payroll withholding in excess of the amount designated by a participant in order to adjust for delays or
mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting
and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the
purchase of Common Stock for each participant properly correspond with amounts withheld from the participant’s
Compensation, and establish such other limitations or procedures as the Administrator determines in its sole
discretion advisable which are consistent with the Plan.

(c) In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable
financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable,
modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not
limited to:

(i) amending the Plan to conform with the safe harbor definition under Statement of Financial

Accounting Standards 123(R), including with respect to an Offering Period underway at the time;

(ii) altering the Purchase Price for any Offering Period including an Offering Period underway at the time

of the change in Purchase Price;

(iii) shortening any Offering Period by setting a New Exercise Date, including an Offering Period

underway at the time of the Administrator action;

(iv) reducing the maximum percentage of Compensation a participant may elect to set aside as payroll

deductions; and

(v) reducing the maximum number of shares a participant may purchase during any Offering Period.

Such modifications or amendments will not require stockholder approval or the consent of any Plan

participants.

21. Notices. All notices or other communications by a participant to the Company under or in connection
with the Plan will be deemed to have been duly given when received in the form and manner specified by the
Company at the location, or by the person, designated by the Company for the receipt thereof.

22. Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an
option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto will comply
with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933,
as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock
exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the
Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to
represent and warrant at the time of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a
representation is required by any of the aforementioned applicable provisions of law.

23. Term of Plan. The Plan will become effective upon the earlier to occur of its adoption by the Board or its
approval by the stockholders of the Company. It will continue in effect for a term of twenty (20) years, unless sooner
terminated under Section 20.

A-8

24. Reimbursement of Taxes. The Administrator shall have the discretion to require reimbursement from any
Plan participant in full for any liability that the Company or the Employer incurs towards any tax paid or payable in
respect to participant’s participation in the Plan, the grant of any option pursuant to the Plan, or the exercise of
participant’s option, provided that such reimbursement is provided for in the subscription agreement. The Company
may require security for such reimbursement of taxes as a precondition to participant participating in the Plan, the
grant of any option, or the exercise of this option on behalf of Participant. The Administrator shall have the authority
to approve additional documents or forms which may be requested by the Company for such security, collection or
otherwise for reimbursement of such taxes to the Company.

25. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within
twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the
manner and to the degree required under Applicable Laws.

PART I

ITEM 1. Business

Overview

We design, develop and sell products and services that together provide our customers with high-performance
network infrastructure that creates responsive and trusted environments for accelerating the deployment of services
and applications over a single Internet Protocol (“IP”)-based network. We serve the high-performance networking
requirements of global service providers, enterprises, governments and research and education institutions that view
the network as critical to their success. High-performance networking is designed to provide fast, reliable and
secure access to applications and services. We offer a high-performance network infrastructure that includes
best-in-class IP routing, Ethernet switching security and application acceleration solutions, as well as partnerships
designed to extend the value of the network and worldwide services and support designed to optimize customer
investments.

In the fiscal year ended December 31, 2007, we experienced growth in both product and service revenues. We
also generated strong net income, operating margin, and cash flows from operations during 2007. We believe these
results were driven by market demands and our focused execution of our two fundamental objectives: To establish
our growth and momentum in the high-performance networking marketplace as reflected by top line performance,
and to improve our leverage against those revenues, as demonstrated by the bottom line improvements in our
financial results.

Our operations are organized into three reportable segments: Infrastructure, Service Layer Technologies
(“SLT”), and Service. Our Infrastructure segment primarily offers scalable routing products that are used to control
and direct network traffic from the core, through the edge, aggregation and the customer premise equipment level.
Infrastructure products include our IP routing and carrier Ethernet routing portfolio, as well as our recently
announced Ethernet switching portfolio. Our SLT segment offers solutions that meet a broad array of our customer’s
priorities, from protecting the network itself, and protecting data on the network, to maximizing existing bandwidth
and acceleration of applications across a distributed network. SLT products include firewall and virtual private
network (“VPN”) systems and appliances, secure sockets layer virtual private network (“SSL”) appliances,
intrusion detection and prevention (“IDP”) appliances, application front end platforms, the J-series router product
family, integrated Secure Services Gateway (“SSG”) secure router product offerings and wide area network
(“WAN”) optimization platforms. Together, our high-performance network infrastructure offerings help enable our
customers to convert legacy networks that provide commoditized, best efforts services into more valuable assets
that provide differentiation and value and increased performance, reliability and security to end users. Our Service
segment delivers world-wide services to customers of the Infrastructure and SLT segments.

During our fiscal year ended December 31, 2007 we generated net revenues of $2.8 billion and conducted
business in more than 100 countries around the world. See Item 8 of Part II for more information on our consolidated
financial position as of December 31, 2007 and 2006 and our consolidated results of operations, consolidated
statements of stockholders’ equity, and consolidated statements of cash flows for each of the three years in the
period ended December 31, 2007.

We were incorporated in California in 1996 and reincorporated in Delaware in 1998. Our corporate head-

quarters are located in Sunnyvale, California. Our website address is www.juniper.net.

Our Strategy

Our objective and strategy is to be the leading provider of high-performance networking. We offer a high-
performance network infrastructure that creates a responsive and trusted environment for accelerating the
deployment of services and applications over a single IP-based network. We believe our open network infra-
structure provides customers with greater choice and control in quickly meeting high-performance business
requirements, while enabling them to reduce costs. Our strategy is designed to advance the fundamentals and
economics of high-performance networking. Key elements of our strategy are described below.

2

Maintain and Extend Technology Leadership

Our application-specific integrated circuit (“ASIC”) technology, JUNOS operating system and network-
optimized product architecture have been key elements to establishing and maintaining our technology leadership.
We believe that these elements can be leveraged into future products that we are currently developing. We intend to
maintain and extend our technological leadership in the service provider and enterprise markets primarily through
innovation and continued investment in our research and development departments, supplemented by external
partnerships, including strategic alliances, as well as acquisitions that would allow us to deliver a broader range of
products and services to customers in target markets.

Leverage Position as Supplier of High-Performance Network Infrastructure

From inception we have focused on designing, developing and building high-performance network infra-
structure for demanding service provider and enterprise networking environments and have integrated purpose-built
technology into a network optimized architecture that specifically meets our customers’ needs. We believe that
many of these customers will deploy networking equipment from only a few vendors. We believe that the
performance, reliability and security of our products provide us with a competitive advantage, which is critical in
gaining selection as one of these vendors.

Be Strategic to Our Customers

In developing our infrastructure and SLT solutions, we work very closely with customers to design and build
best-in-class products specifically designed to meet their complex needs. Over time, we have expanded our
understanding of the escalating demands and risks facing our customers. That increased understanding has enabled
us to subsequently design additional capabilities into our products. We believe our close relationships with, and
constant feedback from, our customers have been key elements in our design wins and rapid deployments to date.
We plan to continue to work hand-in-hand with our customers to implement product enhancements as well as to
design future products that meet the evolving needs of the marketplace, while enabling customers to reduce costs.

Enable New IP-Based Services

Our platforms enable network operators to quickly build and secure networks cost-effectively and deploy new
differentiated services to drive new sources of revenue more efficiently than legacy network products. We believe
that the secure delivery of IP-based services and applications, including IP Television (“IPTV”), web hosting,
outsourced Internet and intranet services, outsourced enterprise applications and voice-over IP, will continue to
grow and are cost-effectively enabled by our high-performance network infrastructure offerings.

Establish and Develop Industry Partnerships

Our customers have diverse requirements. While our products meet certain requirements of our customers, our
products are not intended to satisfy certain other requirements. Therefore, we believe that it is important that we
attract and build relationships with other industry leaders in a diverse set of technologies and services that extend the
value of the network for our customers. These partnerships ensure that we have access to those technologies and
services, whether through technology integration, joint development, resale or other collaboration, in order to better
support a broader set of our customers’ requirements. In addition, we believe in an open network infrastructure that
invites partner innovation and provides customers with greater choice and control in meeting their evolving
business requirements, while enabling them to reduce costs.

3

Markets and Customers

We sell our high-performance network products and service offerings through direct sales and through

distributors and value-added resellers to end-users in the following markets:

Service Providers

Service providers include wireline, wireless, and cable operators as well as major internet content and
application providers. Supporting most major service provider networks in the world, our high-performance
network infrastructure offerings are designed and built for the performance, reliability and security that service
providers demand. Our networking infrastructure offerings benefit these customers by:

• Reducing capital and operational costs by running multiple services over the same network using our high

density, highly reliable platforms;

• Promoting generation of additional revenue by enabling new services to be offered to new market segments

based on our product capabilities;

• Increasing customer satisfaction, while lowering costs, by enabling consumers to self-select automatically

provisioned service packages that provide the quality, speed and pricing they desire; and

• Providing increased asset longevity and higher return on investment as their networks can scale to multi-

terabit rates based on the capabilities of our platforms.

While many of these service providers have historically been categorized separately as wireline, wireless, or
cable operators, in recent years we have seen a move towards convergence of these different types of service
providers through acquisitions, mergers and partnerships. We believe these strategic developments are made
technically possible as operators invest in the build out of next generation networks (“NGN”) capable of supporting
voice, video and data traffic on to the same IP-based network. This convergence relies on IP-based traffic processing
and creates the opportunity for multi-service networks including new service offerings such as IPTV. These new
services offer service providers significant new revenue opportunities.

We believe that there are several other trends affecting service providers for which we are well positioned to
deliver products and solutions. These trends include significant growth in IP traffic on service provider networks as
a result of peer-to-peer interaction, broadband usage, video, and an increasing reliance on the network as a mission
critical business tool in the strategies of our IP customers, and of their enterprise customers.

The IP infrastructure market for service providers includes: products and technology at the network core; the
network edge to enable access; the aggregation layer; security to protect from the inside out and the outside in; the
application awareness and intelligence to optimize the network to meet business and user needs; and the
management, service awareness and control of the entire infrastructure.

We have sold our products to all of the 65 largest service providers in the world.

Enterprise

Our high-performance network infrastructure offerings are designed to meet the performance, reliability and
security requirements of the world’s most demanding businesses. For this reason, enterprises, federal, state and local
governments, and research and education institutions that view their networks as critical to their success are able to
deploy our solutions as a powerful component in delivering the advanced network capabilities needed for their
leading-edge applications while:

• Assisting in the consolidation and delivery of existing services and applications;

• Accelerating the deployment of new services and applications;

• Offering integrated security to assist in the protection and recovery of services and applications; and

• Offering operational improvements that enable cost reductions, including lower administrative, training,

customer care and labor costs.

4

The enterprise market continued to be an important part of our business growth during 2007, driven in
particular by growth in the second half of the year. Since we first entered the market, we have sold our products to
more than 30,000 enterprise customers.

As with the service provider market, innovation continues to be a critical component in our strategy for the
enterprise market. We believe that innovative enterprises view the network as critical to their success and therefore
must build advanced network infrastructures that provide fast, reliable and secure access to services and appli-
cations over a single IP-based network. These high-performance enterprises require networks that are global,
distributed and always available. Network equipment vendors need to demonstrate performance, reliability and
security to these customers in specific segments with best-in-class open solutions for maximum flexibility. We offer
enterprise solutions and services for data centers, branch and campus applications, distributed and extended
enterprises, and WAN gateways.

As customers increasingly view the network as critical to their success, we believe that customers will
increasingly demand fast, reliable and secure access to services and applications over a single IP-based network.
This is partly illustrated by the increasing success of our Integrated Security Gateway (“ISG”) products that
combine firewall/VPN and IDP solutions in a single platform and SSG platforms that provide a mix of high-
performance security with Local Area Network (“LAN”)/WAN connectivity for regional and branch office
deployments. We will continue to invest to develop these and other converged technologies and solutions.

Fundamental Requirements for High Performance Networking

Our service provider customers have clearly communicated their fundamental business requirement to quickly

and cost-effectively deploy new differentiated services to drive new sources of revenue.

Our enterprise customers are under pressure to accelerate the delivery of service-enabling applications to build

differentiation and sustainable growth.

In parallel, both service providers and enterprises must focus on proactively detecting and preventing the ever
increasing number of security threats facing the network itself and the data that flows across the network. This
security must be innate to networking products and must not come at the expense of overall performance or
unjustifiable cost.

This is driving the fundamental requirement for high-performance networking, providing fast, reliable and
secure access to applications and services over a single IP-based network. Feature richness, high reliability, security,
high performance, scalability, and cost effectiveness are each fundamental requirements in meeting the needs
associated with the growth in IP traffic and the delivery of value-added services to end users.

Feature Richness. The importance of increasing revenue streams and decreasing capital and operational
costs for our customers is a significant priority in the industry. Service providers want to quickly and cost effectively
deploy new differentiated services to drive new sources of revenue. Enterprises and other network operators want to
accelerate the delivery of service-enabling applications to build differentiation and growth. Each of these goals is
ultimately a function of the features and capabilities that can be securely provided on each of the network elements.
As networks advance, more and more features are required to sell new services as well as to lower the ongoing costs
of operating the network. Next generation networking solutions therefore need to have flexibility to add new
capabilities frequently without compromising the performance of the system, which gets increasingly difficult as
the network demands increase.

High Reliability. As businesses and consumers increasingly rely on IP networks for mission-critical
applications, high network reliability is critical to success. As a result, those businesses and consumers expect
service providers to deliver a high degree of reliability in their networks.

Security. Today’s network environment presents an ever-increasing number of challenges regarding network
security ranging from simple denial of service attacks to sophisticated, pervasive and malicious intrusions. The
importance of security is increasing within all of our customers and we are continually improving and evolving the
security capabilities on all of our product solutions. It is extremely important to provide comprehensive network-

5

based security services that are fully integrated, free of performance trade-offs, and scaleable to any customer or
market.

High-Performance Without Compromising Intelligence. To handle the rapid growth in IP traffic, today’s
customers increasingly require fast, reliable and secure networking solutions that can operate at higher speeds,
while still delivering real-time services such as security and quality-of-service features. The processing of data
packets at these high speeds requires sophisticated forwarding technology to inspect each packet and assign it to a
destination based on priority, data type and other considerations. Because a large number of IP packets, many of
which perform critical administrative functions, are small in size, high-performance IP routers need to achieve their
specified transmission speeds even for small packet sizes. Because smaller packets increase packet processing
demands, routing large numbers of smaller packets tends to be more resource intensive than routing of larger
packets. A wire speed router, which achieves its specified transmission rate for any type of traffic passing through it,
can accomplish this task. Thus, provisioning of mission-critical services increasingly requires the high performance
enabled by wire speed processing.

High-Performance Under Stressful Conditions.

In a large and complex network, individual components
inevitably fail. However, the failure of an individual device or link must not compromise the network as a whole. In
a typical network, when a failure occurs, the network loses some degree of capacity and, in turn, a greater load falls
on the remaining network routers, which must provide alternate routes. High-performance network infrastructure
must quickly adapt to the new state of the network to maintain packet forwarding rates and avoid dropping
significant numbers of packets when active routes are lost or when large numbers of routes change. Routing
protocols are used to accomplish this convergence, a process that places even greater stress on the router. Given the
complexity of IP network infrastructure, the convergence process is complex and places a far greater load on the
router, thereby requiring a much more sophisticated device.

Scalability. Due to the rapid growth in IP traffic, service providers must continuously expand their networks,
both in terms of increased numbers of access points of presence (“PoPs”), and also greater capacity per PoP. To
facilitate this expansion process, secure networking solutions must be highly scalable. Next generation network
appliances therefore need to be flexible and configurable to function within constantly changing networks while
incurring minimal downtime.

High Return on Investment. Continued growth in IP traffic, price competition in the telecommunications
market and increasing pressure for network operators to attain higher returns on their network infrastructure
investments all contribute to our customers’ desire for solutions that significantly reduce the capital expenditures
required to build and operate their networks. In addition to the basic cost of equipment, network operators incur
substantial ancillary costs for the space required to deploy the equipment, power consumed and ongoing operation
and maintenance of the equipment. Network operators therefore want to deploy dense and varied equipment
configurations in limited amounts of rack and floor space, with increasing consideration to energy and cooling
requirements and costs. Therefore, in order to continue to scale their networks toward higher data speeds in a cost
effective manner, network operators need the ability to mix and match easily many different speed connections at
appropriate densities, without significantly increasing the consumption of space or power and driving costs higher.

These requirements define a clear need for high-performance networking solutions that have been designed to
support high speeds and offer new IP-based services. At the same time, network operators are eagerly seeking new
solutions that increase the level of scalability and reliability within their networks, while reducing the cost and
complexity of their architectures.

Our Technology and Products

Early in our history, we developed, marketed and sold the first commercially available purpose-built IP
backbone router optimized for the specific high-performance requirements of service providers. As the need for
core bandwidth continued to increase, the need for service rich platforms at the edge of the network was created.
Our infrastructure products are designed to address the needs at the core and the edge of the network as well as for
wireless access by combining high-performance packet forwarding technology and robust operating systems into a
network-optimized solution. In addition, as enterprises continue to develop and rely upon more sophisticated and
pervasive internal networks, we believe the need for products with high-performance routing technology is

6

expanding to a broader set of customers, and we believe our expertise in this technology uniquely positions us to
address this growing market opportunity.

Additionally, we offer a broad family of network security solutions that deliver high-performance, cost-
effective security for enterprises, service providers and government entities, including firewall and VPN systems
and appliances, SSL appliances, and IDP appliances. With the 2005 acquisitions of Funk Software, Inc. (“Funk”),
Peribit Networks, Inc. (“Peribit”), Redline Networks, Inc. (“Redline”), and Kagoor Networks, Inc. (“Kagoor”), we
added complementary products and technologies to our product families that enable our customers to provide
additional IP-based services and enhance the performance and security of their existing networks and applications.

Infrastructure Products

We believe that an overview of the physical nature of our infrastructure products is helpful in understanding the

operation of our business.

Although specific designs vary among our product families, our router platforms are essentially modular, with
the chassis serving as the base of the platform. The chassis contains components that enable and support many of the
fundamental functions of the router, such as power supplies, cooling fans, and components that run the operating
system, perform high-speed packet forwarding, or keep track of the structure of the network and instruct the packet
forwarding components where to send packets. Each chassis has a certain number of slots that are available to be
populated with components we refer to as modules or interfaces.

The modules are the components through which the router receives incoming packets of data from the network
over a variety of transmission media. The physical connection between a transmission medium and a module is
referred to as a port. The number of ports on a module varies widely depending on the functionality and throughput
offered by the module. In some cases, modules do not contain ports or physically receive packets from the network,
but rather provide additional capabilities or features that enhance the overall functionality of the router. We refer to
these components as service modules.

Our new EX-Series family of Ethernet switches include Virtual Chassis and fixed configuration design
elements. Virtual Chassis technology allows up to ten switches to be interconnected and operate as a single system,
thereby enabling higher port density in a compact and efficient form factor. Our fixed configuration switch
platforms offer a cost-effective standalone solution for low-density deployments.

Major infrastructure product families are summarized as follows:

• M-Series and T-Series: Our M-series routers are extremely versatile as they can be deployed at the edge of
operator networks, in small and medium core networks, enterprise networks and in other applications. The
M-series product family includes the M320, M160, M120, M40e, M20, M10i and M7i platforms. Our
T-series core routers, T1600, T640, T320, and TX Matrix, are primarily designed for core IP infrastructures
and are also being sold into the multi-service environment (“MSE”). The M-series and T-series products
leverage our ASIC technology and the same JUNOS operating system to enable consistent, continuous,
reliable and predictable service delivery.

• E-Series: Our E-series products are a full featured platform with support for carrier-class routing,
broadband subscriber management services and a comprehensive set of IP services. The E-series family
includes the ERX-1440, -1410, -710, -705 and -310 platforms and the E320 and E120 broadband service
routers. Leveraging our JUNOSe operating system, the E-Series service delivery architecture enables
service providers to easily deploy innovative revenue generating services to their customers and avoid the
costly and limiting piecemeal outcomes that result from equipment that delivers inconsistent edge services.
All E-Series platforms offer a full suite of routing protocols and provide scalable capacity for tens of
thousands of users.

• MX-Series: The MX-Series is a product family developed to address emerging Ethernet network archi-
tectures and services in service provider and enterprise networks, and includes the MX960, MX480 and
MX240. Using our JUNOS operating system, the MX platforms provide the carrier-class performance, scale
and reliability to enable service providers and enterprises to support large scale Ethernet deployments.

7

• EX-Series:

In January 2008, we announced our EX-series family of Ethernet switches, expanding our
product portfolio running our JUNOS operating system. Ethernet is a widely-used technology used to
transport information in enterprise networks. We believe our new EX-series switches will enable customers
to accelerate and simplify the way they install and manage business applications across their networks and
enhance network operations without comprising performance.

SLT Products

SLT products provide network security solutions and enable our customers to provide additional IP-based

services and enhance the performance and security of their existing networks and applications.

Major SLT product families are summarized as follows:

• Firewall and VPN Systems: Our NS-5400, -5200, and -500 products and ISG-2000 and -1000 products are
high-performance security systems designed to provide integrated firewall, VPN and denial of service
protection capabilities for enterprise environments and service provider network infrastructures. Our
ISG-2000 and -1000 products can also deliver intrusion detection and prevention functionality with the
addition of optional security modules to the base ISG chassis. Each of our firewall and VPN systems can be
deployed in high bandwidth environments and can be used to deliver managed security services. Our firewall
and VPN systems allow unique security policies to be enforced for multiple virtual local area networks, or
Virtual LANs (“VLANs”), allowing a single system to secure multiple networks. Our security systems also
allow for the creation of multiple Virtual Systems, each providing a unique security domain with its own
virtual firewall and VPN and dedicated management interface. These features enable enterprises, service
providers and government entities to use a single security system to secure multiple networks and enable
carriers to deliver security services to multiple customers.

• Firewall and VPN Appliances: Our SSG family of secure routing products represents a new class of
purpose-built security appliance that delivers a mix of high performance, security and LAN/WAN
connectivity for regional and branch office deployments. The SSG appliances combine proven firewall/
VPN and robust routing with a set of Unified Threat Management (“UTM”) security features to protect
traffic as it flows in and out of the branch office. Our NS-208, -204, -100, -50, -25, -5XT and -5XP security
appliances are fixed configuration products of varying performance characteristics that offer integrated
firewall, VPN and denial of service protection capabilities. Our security appliances are designed to
maximize security and performance while using less physical space than competing products. Our security
appliances can be deployed to provide small to medium-sized businesses and enterprise remote locations
with secure Internet access and communication.

• SSL VPN Appliances: Our Secure Access-6000, -4000, -2000, and -700 appliances are used to secure
remote access for mobile employees, secure extranets for customers and partners, and secure intranets. Our
SSL VPN appliances are designed to be used in enterprise environments of all sizes.

• IDP Appliances: Our IDP-1100, -600, -200 and -50 appliances utilize intrusion detection methods to
increase the attack detection accuracy and provide the broadest attack detection coverage available. Our IDP
appliances provide fast and efficient traffic processing and alarm collection, presentation and forwarding.
Once an attack is detected, our IDP appliances prevent the intrusion by dropping the packets or connection
associated with the attack, reducing or eliminating the effects of the attack. Our IDP appliances can also alert
the IT staff to respond to the attack. Our IDP appliances can be clustered to provide high availability and
reduce risk associated with a single point of failure.

• Application Acceleration Platforms: Our WX and WXC products improve the performance of
client-server and web-enabled business applications for branch-office, remote, and mobile users. These
application acceleration platforms enable our customers to deliver LAN-like performance to users around
the globe who access centralized applications.

• Unified Access Control (“UAC”) Solution: Using our UAC 2.1 solution, our IC-4000 and -6000 appliances
combine identity-based policy and end-point intelligence to give enterprises real-time visibility and policy
control throughout the network.

8

• AAA and 802.1X Products: Our family of AAA and 802.1X network access security products, including
our Odyssey Access Client and Steel Belted Radius products, are a key component to uniform security
policy enforcement across all network access methods, including wireless LAN, remote/VPN, dial, and
identity-based (wired 802.1X) methods.

In 2007 and the first quarter of 2008, we announced several significant new products in our Infrastructure and

SLT product categories including, but not limited to, the following:

Infrastructure:

• Our portfolio of Session and Resource Control solutions, which provide subscriber management and policy
control capabilities, enabling service providers to deliver a high-quality user experience for “multi-play” and
mobile services in next-generation networks. The Session and Resource Control portfolio features modular
software applications that build upon the feature set of our SDX-300 Service Deployment System, and the
new C-series family of controllers which support end-to-end policy management on a dedicated,
purpose-built platform.

• The newest member of the T-series family, the T1600 core router. Capable of delivering 1.6 Tbps of
throughput in a single half-rack chassis, the T1600 core router is designed to ease the transition to
next-generation networks and enable service providers to efficiently accelerate the deployment of the
services demanded by their customers.

• The E120 broadband services router, a platform capable of delivering up to 120 Gbps of capacity in a
compact chassis with support for up to 64,000 individual subscribers. This router enables service providers
to efficiently generate incremental revenue and shares the same proven JUNOSe operating system, line cards
and interface modules as the widely-deployed E320 router.

• An expansion of our MX-Series family of Ethernet Services Routers with the additions of the MX480 and
MX240. Designed to address emerging Ethernet network architectures and services, each platform scales to
support over 1 million media access control (“MAC”) addresses which enables service providers to
effectively scale Ethernet to support large service provider deployments.

• The EX-series of Ethernet switches described above.

SLT:

• ScreenOS version 6.0 operating system for the ISG and SSG platforms and version 4.1 software for our IDP
products. These software releases provide our customers with advanced visibility and control of applications
and users, enabling them to set and enforce security policies across the network and enhance application
delivery and performance to improve user productivity and to keep pace with escalating business
requirements.

• The J2320 and J2350 J-series services routers, SSG 320M and SSG 350M security platforms and two new
network management appliances with NetScreen-Security Manager (“NSM”) Central Manager and
NSMXpress. The new J-series, SSG and NSM products are designed to enable enterprises to accelerate
the secure delivery of business critical applications across their networks.

• Software enhancements to our SSL VPN appliances that provide support for a broader array of applications
and platforms, enhanced access control, and policy enforcement capabilities designed to meet the require-
ments of high-performance businesses.

• Version 2.1 of UAC solution, advancing our ability to address the evolving access control and security
requirements of customers. UAC 2.1 helps reduce the complexity of securing access to networks and
applications and delivers access control, visibility and monitoring of applications and users to help address
regulatory compliance while mitigating risk and exposure to today’s rapidly evolving threat landscape.

9

• New additions to our WX and WXC application acceleration platforms fortified application security without
compromising performance and enhancements to the WX Central Management System allow for the
integration of content distribution and WAN optimization within a single platform.

See Note 11 in Item 8 for a breakdown of net product revenues by segment.

Customer Service and Support

In addition to Infrastructure products and SLT products, we offer the following services: 24x7x365 technical
assistance, hardware repair and replacement parts, unspecified software updates on a when and if available basis,
professional services and educational services. We deliver these services directly to major end users and also utilize
a multi-tiered support model,
leveraging the capabilities of our partners and third-party organizations as
appropriate.

We also train our channel partners in the delivery of education and support services to ensure locally delivered

training.

As of December 31, 2007, we employed 748 people in our worldwide customer service and support
organization. We believe that a broad range of support services is essential to the successful customer deployment
and ongoing support of our products and we have hired support engineers with proven network experience to
provide those services.

Manufacturing and Operations

As of December 31, 2007, we employed 190 people in manufacturing and operations who primarily manage
relationships with our contract manufacturers, manage our supply chain, and monitor and manage product testing
and quality.

We have manufacturing relationships primarily with Celestica, Flextronics and Plexus, under which we have
subcontracted the majority of our manufacturing activity. Our manufacturing activity is primarily conducted in
Canada, China and the United States.

This subcontracting activity in all locations extends from prototypes to full production and includes activities
such as material procurement, final assembly, test, control, shipment to our customers and repairs. Together with
our contract manufacturers, we design, specify and monitor the tests that are required to meet internal and external
quality standards. These arrangements provide us with the following benefits:

• We can quickly deliver products to customers with turnkey manufacturing and drop-shipment capabilities;

• We gain economies of scale because, by purchasing large quantities of common components, our contract

manufacturers obtain more favorable pricing than if we were buying components alone;

• We operate without dedicating significant space to manufacturing operations; and

• We can reduce our costs by reducing fixed overhead expenses.

Our contract manufacturers manufacture our products based on rolling forecasts from us about our product
demands. Each of the contract manufacturers procures components necessary to assemble the products in our
forecast and test the products according to our specifications. Products are then shipped to our distributors, value-
added resellers or end-users. Generally, we do not own the components and title to the products transfers from the
contract manufacturers to us and immediately to our customers upon delivery at a designated shipment location. If
the components go unused or the products go unsold for specified periods of time, we may incur carrying charges or
obsolete material charges for components that our contract manufacturers purchased to build products to meet our
forecast or customer orders.

Although we have contracts with our contract manufacturers, those contracts merely set forth a framework
within which the contract manufacturer may accept purchase orders from us. The contracts do not require them to
manufacture our products on a long-term basis.

10

Our ASICs are manufactured primarily by sole or limited sources, such as IBM Corporation and Toshiba
Corporation, each of whom is responsible for all aspects of the production of the ASICs using our proprietary
designs.

Juniper Networks has at its core five key values: trust, integrity, respect, humility and excellence. These values
are integral to how we manage our company and interact with our employees, customers, partners and suppliers. By
working collaboratively with our suppliers, we also have the opportunity to promote socially responsible business
practices beyond Juniper Networks and into our worldwide supply chain. To this end, we have adopted, and promote
the adoption by others, of the Electronic Industry Code of Conduct. The Electronic Industry Code of Conduct
outlines standards to ensure that working conditions in the electronics industry supply chain are safe, that workers
are treated with respect and dignity, and that manufacturing processes are environmentally responsible.

Research and Development

As of December 31, 2007, we employed 2,563 people in our worldwide research and development organi-
zations. Our research and development expenses totaled $623.0 million, $480.3 million and $357.3 million in the
years ended December 31, 2007, 2006 and 2005, respectively. We have assembled a team of skilled engineers with
extensive experience in the fields of high-end computing, network system design, ASIC design, security, routing
protocols and embedded operating systems. These individuals have worked in leading computer data networking
and telecommunications companies.

We believe that strong product development capabilities are essential to our strategy of enhancing our core
technology, developing additional applications, incorporating that technology and maintaining the competitiveness
of our product and service offerings. In our infrastructure and SLT products, we are leveraging our ASIC
technology, developing additional network interfaces targeted to our customer applications and continuing to
develop next generation technology to support the anticipated growth in IP network requirements. We continue to
expand the functionality of our products to improve performance reliability and scalability, and to provide an
enhanced user interface.

Our research and development process is driven by the availability of new technology, market demand and
customer feedback. We have invested significant time and resources in creating a structured process for all product
development projects. Following an assessment of market demand, our research and development team develops a
full set of comprehensive functional product specifications based on inputs from the product management and sales
organizations. This process is designed to provide a framework for defining and addressing the steps, tasks and
activities required to bring product concepts and development projects to market.

Sales and Marketing

As of December 31, 2007, we employed 1,863 people in our worldwide sales and marketing organizations.

These sales employees operate in different locations around the world in support of our customers.

Our sales organization is organized into three geographic regions and within each region according to the
particular needs in that market. Our three geographic regions are (i) the Americas (including United States, Canada,
Mexico, Central and South America), (ii) Europe, Middle East and Africa and (iii) Asia Pacific. Within each region
there are regional and country teams to ensure we operate close to the customer.

The sales teams operate in their respective regions and generally either engage customers directly or manage
customer opportunities through our distribution and reseller relationships or channels as described below. In the
United States and Canada, we sell to several service providers directly and sell to other service providers and
enterprise customers primarily through resellers. Almost all of our sales outside the United States and Canada are
made through our channel partners.

See Note 11 in Item 8 for information concerning our revenues by significant customers and by geographic
region. Our operations subject us to certain risks and uncertainties associated with international operations. See
Item 1A of Part I, “Risk Factors” for more information.

11

Direct Sales Structure

Where we have a direct relationship with our customers, the terms and conditions are governed either by
customer purchase orders and our acknowledgement of those orders or by purchase contracts. In instances where we
have direct contracts with our customers, those contracts set forth only general terms of sale and do not require
customers to purchase specified quantities of our products. For this type of customer our sales team engages directly
with the customer. Customer purchase orders are received, and processed directly, by Juniper Networks.

Channel Sales Structure

A critical part of our sales and marketing efforts are our channel partners through which we do the majority of

our business. We employ various channel partners:

• A global network of strategic distribution relationships, as well as region or country-specific distributors
who in turn sell to local value added resellers who sell to the end-user customer. The distribution channel
partners mainly sell our SLT products plus some router products that are often purchased by our enterprise
customers. These distributors tend to be focused on particular regions or particular countries within regions.
For example, we have substantial distribution relationships with Ingram Micro in the Americas and with
NEC in Japan. Our agreements with these distributors are generally non-exclusive, limited by region, and
provide product discounts and other ordinary terms of sale. These agreements do not require our distributors
to purchase specified quantities of our products.

• Direct value-added resellers including our strategic resellers referenced below, which resell our products to
end-users around the world. These direct value-added resellers buy the products and services directly from
us and have expertise in deploying complex networking solutions in their respective markets. Our agree-
ments with these direct value-added resellers are generally non-exclusive, limited by region, and provide
product discounts and other ordinary terms of sale. These agreements do not require our direct value-added
resellers to purchase specified quantities of our products.

• Strategic world-wide reseller relationships with Nokia-Siemens Networks B.V. (“NSN”), Ericsson Telekom
A.B. and Alcatel-Lucent. These companies each offer services and products that complement, but in some
cases compete with, our own product offerings and act as a fulfillment partner for our products. Our
arrangements with each of these partners allow them to resell our products on a worldwide, non-exclusive
basis, provide for discounts based upon the volume of products sold and specify other general terms of sale.
The agreements do not require these partners to purchase specified quantities of our products. NSN
accounted for greater than 10% of our total net revenues in 2007.

Within each region we employ sales professionals to assist with the management of our various sales channels.
In addition we have a “direct touch” sales team that works directly with the channel partners on key accounts in
order to maintain a direct relationship with our more strategic end user customers while at the same time supporting
the ultimate fulfillment of product through our channel partners.

Our sales organization is generally split between service provider and enterprise customers, with each separate
team ensuring focus on the key customers in these respective markets. There is a structure of sales professionals,
system engineers, and marketing and channel teams each focused on the respective service provider and enterprise
markets.

Backlog

Our sales are made primarily pursuant to purchase orders under framework agreements with our customers. At
any given time, we have orders for products that have not been shipped and for services that have not yet been
performed for various reasons. Because we believe industry practice would allow customers to cancel or change
orders with limited advance notice prior to shipment or performance, as well as our history of allowing such changes
and cancellations, we do not consider this backlog to be firm and do not believe our backlog information is
necessarily indicative of future revenue.

12

Seasonality

Many companies in our industry experience adverse seasonal fluctuations in customer spending patterns,
particularly in the first and third quarters. In addition, our SLT segment has experienced seasonally strong customer
demand in the fourth quarter. This historical pattern should not be considered a reliable indicator of our future net
revenues or financial performance.

Competition

Infrastructure Business

In the network infrastructure business, Cisco Systems has historically been the dominant player in the market.
However, other companies such as Alcatel-Lucent, Ericsson, Extreme Networks, Inc., Foundry Networks, Inc.,
Huawei Technologies Co., Ltd., and Nortel Networks Corporation, are providing competitive products in the
marketplace.

Many of our current and potential competitors, such as Cisco, Alcatel-Lucent, Huawei and Nortel have
significantly broader product lines than we do and may bundle their products with other networking products in a
manner that may discourage customers from purchasing our products. In addition, consolidation among compet-
itors, or the acquisition of our partners and resellers by competitors, can increase the competitive pressure faced by
us. For example, in 2006 Alcatel combined with Lucent Technologies, Inc. and Ericsson acquired Redback
Networks. Also, many of our current and potential competitors have greater name recognition and more extensive
customer bases that could be leveraged. Increased competition could result in price reductions, fewer customer
orders, reduced gross margins and loss of market share, any of which could seriously harm our operating results.

SLT Business

In the market for SLT products, Cisco generally is our primary competitor with its broad range of products. In
addition, there are a number of other competitors for each of the product lines within SLT, including Checkpoint
Software Technologies, Fortinet, Inc., F5 Networks, Inc., Nortel and Riverbed Technology, Inc. These additional
competitors tend to be focused on single product line solutions and therefore are generally specialized and focused
as competitors to our products. In addition, a number of public and private companies have announced plans for new
products to address the same needs that our products address. We believe that our ability to compete with Cisco and
others depends upon our ability to demonstrate that our products are superior in meeting the needs of our current and
potential customers.

For both product groups we expect that, over time, large companies with significant resources, technical
expertise, market experience, customer relationships and broad product lines, such as Cisco, Alcatel-Lucent,
Huawei and Nortel, will introduce new products which are designed to compete more effectively in the market.
There are also several other companies that claim to have products with greater capabilities than our products.
Consolidation in this industry has begun, with one or more of these companies being acquired by large, established
suppliers of network infrastructure products, and we believe it is likely to continue.

As a result, we expect to face increased competition in the future from larger companies with significantly
more resources than we have. Although we believe that our technology and the purpose-built features of our
products make them unique and will enable us to compete effectively with these companies, we cannot guarantee
that we will be successful.

Environment

We are subject to regulations that have been adopted with respect to environmental matters, such as the Waste
Electrical and Electronic Equipment (“WEEE”) and Restriction of the Use of Certain Hazardous Substances in
Electrical and Electronic Equipment (“RoHS”) regulations adopted by the European Union. In addition, in
September 2007, we announced our sponsorship and continued participation in the Carbon Disclosure Project
(“CDP”). CDP is a global standardized mechanism by which companies report their greenhouse gas emissions to
institutional investors; it hosts one of the largest registries of corporate greenhouse gas data in the world at
www.cdproject.net. We continue to invest in the infrastructure and systems required to be able to inventory and

13

measure our carbon footprint on a global basis. Since 2005, we have made significant strides in improving our
energy efficiency around the world.

Compliance with federal, state, local, and foreign laws enacted for the protection of the environment has to

date had no material effect on our capital expenditures, earnings, or competitive position.

In addition, we are committed to the environment by our effort in improving the energy efficiency of key
elements of our high-performance network product offerings. For example, our T1600 router consumes substan-
tially less energy than competitive products. The environment will remain a focus area across multiple aspects of
our business.

Intellectual Property

Our success and ability to compete are substantially dependent upon our internally developed technology and
know-how. Our operating systems were developed internally and are protected by United States and other copyright
laws.

While we rely on patent, copyright, trade secret and trademark law to protect our technology, we also believe
that factors such as the technological and creative skills of our personnel, new product developments, frequent
product enhancements and reliable product maintenance are essential to establishing and maintaining a technology
leadership position. There can be no assurance that others will not develop technologies that are similar or superior
to our technology.

In addition, we integrate licensed third-party technology into certain of our products. From time to time, we
may be required to license additional technology from third parties to develop new products or product enhance-
ments. There can be no assurance that third-party licenses will be available or continue to be available to us on
commercially reasonable terms. Our inability to maintain or re-license any third-party licenses required in our
products or our inability to obtain third-party licenses necessary to develop new products and product enhancements
could require us to obtain substitute technology of lower quality or performance standards or at a greater cost, any of
which could harm our business, financial condition, and results of operations.

Our success will depend upon our ability to obtain necessary intellectual property rights and protect our
intellectual property rights. We cannot be certain that patents will be issued on the patent applications that we have
filed, or that we will be able to obtain the necessary intellectual property rights or that other parties will not contest
our intellectual property rights.

Employees

As of December 31, 2007, we had 5,879 full-time employees. We have not experienced any work stoppages,
and we consider our relations with our employees to be good. Competition for personnel in our industry is intense.
We believe that our future success depends in part on our continued ability to hire, motivate and retain qualified
personnel. We believe that we have been successful in recruiting qualified employees, but there is no assurance that
we will continue to be successful in the future.

Our future performance depends in significant part upon the continued service of our key technical, sales and
senior management personnel, none of whom is bound by an employment agreement requiring service for any
defined period of time. The loss of the services of one or more of our key employees could have a material adverse
effect on our business, financial condition and results of operations. Our future success also depends on our
continuing ability to attract, train and retain highly qualified technical, sales and managerial personnel. Competition
for such personnel is intense, and there can be no assurance that we can retain our key personnel in the future.

ITEM 1A. Risk Factors

Factors That May Affect Future Results

Investments in equity securities of publicly traded companies involve significant risks. The market price of our
stock reflects a higher multiple of expected future earnings than many other companies. Accordingly, even small
changes in investor expectations for our future growth and earnings, whether as a result of actual or rumored
financial or operating results, changes in the mix of the products and services sold, acquisitions, industry changes or
other factors, could trigger, and have triggered, significant fluctuations in the market price of our common stock.
Investors in our securities should carefully consider all of the relevant factors, including, but not limited to, the
following factors, that could affect our stock price.

Our quarterly results are inherently unpredictable and subject to substantial fluctuations and, as a result,
we may fail to meet the expectations of securities analysts and investors, which could adversely affect the
trading price of our common stock.

Our revenues and operating results may vary significantly from quarter to quarter due to a number of factors,

many of which are outside of our control and any of which may cause our stock price to fluctuate.

The factors that may affect the unpredictability of our quarterly results include, but are not limited to, limited
visibility into customer spending plans, changes in the mix of products sold, changing market conditions, including
current and potential customer consolidation, competition, customer concentration, long sales and implementation

16

cycles, regional economic and political conditions and seasonality. For example, many companies in our industry
experience adverse seasonal fluctuations in customer spending patterns, particularly in the first and third quarters.

As a result, we believe that quarter-to-quarter comparisons of operating results are not necessarily a good
indication of what our future performance will be. It is likely that in some future quarters, our operating results may
be below the expectations of securities analysts or investors, in which case the price of our common stock may
decline. Such a decline could occur, and has occurred in the past, even when we have met our publicly stated
revenue and/or earnings guidance.

Fluctuating economic conditions make it difficult to predict revenues for a particular period and a
shortfall in revenues may harm our operating results.

Our revenues depend significantly on general economic conditions and the demand for products in the markets
in which we compete. Economic weakness, customer financial difficulties and constrained spending on network
expansion have previously resulted (for example, in 2001 and 2002), and may in the future result, in decreased
revenues and earnings and could negatively impact our ability to forecast and manage our contract manufacturer
relationships. Economic downturns may also lead to restructuring initiatives and associated expenses and
impairment of investments. In addition, our operating expenses are largely based on anticipated revenue trends
and a high percentage of our expenses are, and will continue to be, fixed in the short-term. Uncertainty about future
economic conditions makes it difficult to forecast operating results and to make decisions about future investments.
Future economic weakness, customer financial difficulties and reductions in spending on network expansion could
have a material adverse effect on demand for our products and consequently on our results of operations and stock
price.

Telecommunications companies and other large companies generally require more onerous terms and
conditions of their vendors. As we seek to sell more products to such customers, we may be required to
agree to terms and conditions that may have an adverse effect on our business or ability to recognize
revenues.

Telecommunications service provider companies and other large companies, because of their size, generally
have had greater purchasing power and, accordingly, have requested and received more favorable terms, which
often translate into more onerous terms and conditions for their vendors. As we seek to sell more products to this
class of customer, we may be required to agree to such terms and conditions, which may include terms that affect the
timing of our ability to recognize revenue and have an adverse effect on our business and financial condition.
Consolidation among such large customers can further increase their buying power and ability to require onerous
terms.

For example, many customers in this class have purchased products from other vendors who promised certain
functionality and failed to deliver such functionality and/or had products that caused problems and outages in the
networks of these customers. As a result, this class of customers may request additional features from us and require
substantial penalties for failure to deliver such features or may require substantial penalties for any network outages
that may be caused by our products. These additional requests and penalties, if we are required to agree to them,
may affect our ability to recognize the revenues from such sales, which may negatively affect our business and our
financial condition. For example, in April 2006, we announced that we would be required to defer a large amount of
revenue from a customer due to the contractual obligations required by that customer.

For arrangements with multiple elements, vendor specific objective evidence of fair value of the undelivered
element is required in order to separate the components and to account for elements of the arrangement separately.
Vendor specific objective evidence of fair value is based on the price charged when the element is sold separately.
However, customers may require terms and conditions that make it more difficult or impossible for us to maintain
vendor specific objective evidence of fair value for the undelivered elements to a similar group of customers, the
result of which could cause us to defer the entire arrangement fees for a similar group of customers (product,
maintenance, professional services, etc.) and recognize revenue only when the last element is delivered or if the
only undelivered element is maintenance revenue would be recognized ratably over the contractual maintenance
period which is generally one year but could be substantially longer.

17

If we do not successfully anticipate market needs and develop products and product enhancements that
meet those needs, or if those products do not gain market acceptance, we may not be able to compete
effectively and our ability to generate revenues will suffer.

We cannot guarantee that we will be able to anticipate future market needs or be able to develop new products
or product enhancements to meet such needs or to meet them in a timely manner. If we fail to anticipate market
requirements or to develop new products or product enhancements to meet those needs, such failure could
substantially decrease market acceptance and sales of our present and future products, which would significantly
harm our business and financial results. Even if we are able to anticipate, develop and commercially introduce new
products and enhancements, there can be no assurance that new products or enhancements will achieve widespread
market acceptance. For example, in the first quarter of 2008 we announced new products designed to address the
Ethernet switch market, a market in which we have not had a historical presence. If these new products do not gain
market acceptance at a sufficient rate of growth, or at all, our ability to meet future financial targets may be
adversely affected. Any failure of our products to achieve market acceptance could adversely affect our business
and financial results.

We expect gross margin to vary over time and our recent level of product gross margin may not be
sustainable.

Our product gross margins will vary from quarter to quarter and the recent level of gross margins may not be
sustainable and may be adversely affected in the future by numerous factors, including product mix shifts, increased
price competition in one or more of the markets in which we compete, increases in material or labor costs, excess
product component or obsolescence charges from our contract manufacturers, increased costs due to changes in
component pricing or charges incurred due to component holding periods if our forecasts do not accurately
anticipate product demand, warranty related issues, or our introduction of new products or entry into new markets
with different pricing and cost structures.

We rely on value-added resellers and distribution partners to sell our products, and disruptions to, or our
failure to effectively develop and manage, our distribution channel and the processes and procedures that
support it could adversely affect our ability to generate revenues from the sale of our products.

Our future success is highly dependent upon establishing and maintaining successful relationships with a
variety of value-added reseller and distribution partners. The majority of our revenues are derived through value-
added resellers and distributors, most of which also sell competitors’ products or their own competitive products.
Our revenues depend in part on the performance of these partners. The loss of or reduction in sales to our value-
added resellers or distributors could materially reduce our revenues. During 2006, Alcatel, a value-added reseller
and a competitor of ours, acquired Lucent, one of our largest value-added resellers. In addition, in April 2007 our
largest customer, Siemens, transferred its telecommunications business to Nokia-Siemens Networks, a joint venture
between Siemens and Nokia. Our competitors may in some cases be effective in providing incentives to current or
potential resellers and distributors to favor their products or to prevent or reduce sales of our products. If we fail to
maintain relationships with our partners, fail to develop new relationships with value-added resellers and distrib-
utors in new markets or expand the number of distributors and resellers in existing markets, fail to manage, train or
motivate existing value-added resellers and distributors effectively or if these partners are not successful in their
sales efforts, sales of our products may decrease and our operating results would suffer.

In addition, we recognize a portion of our revenue based on a sell-through model using information provided
by our distributors. If those distributors provide us with inaccurate or untimely information, the amount or timing of
our revenues could be adversely impacted.

Further, in order to develop and expand our distribution channel, we must continue to scale and improve our
processes and procedures that support it, and those processes and procedures may become increasingly complex and
inherently difficult to manage. Our failure to successfully manage and develop our distribution channel and the
processes and procedures that support it could adversely affect our ability to generate revenues from the sale of our
products.

18

If we fail to accurately predict our manufacturing requirements, we could incur additional costs or
experience manufacturing delays which would harm our business.

We provide demand forecasts to our contract manufacturers. If we overestimate our requirements, the contract
manufacturers may assess charges or we may have liabilities for excess inventory, each of which could negatively
affect our gross margins. Conversely, because lead times for required materials and components vary significantly
and depend on factors such as the specific supplier, contract terms and the demand for each component at a given
time, if we underestimate our requirements, the contract manufacturers may have inadequate time or materials and
components required to produce our products, which could increase costs or could delay or interrupt manufacturing
of our products and result in delays in shipments and deferral or loss of revenues.

Our ability to process orders and ship products in a timely manner is dependent in part on our business
systems and performance of the systems and processes of third parties such as our contract manufacturers,
suppliers or other partners, as well as interfaces with the systems of such third parties. If our systems, the
systems and processes of those third parties or the interfaces between them experience delays or fail, our
business processes and our ability to build and ship products could be impacted, and our financial results
could be harmed.

Some of our business processes depend upon our information technology systems, the systems and processes
of third parties and on interfaces with the systems of third parties. For example, our order entry system feeds
information into the systems of our contract manufacturers, which enables them to build and ship our products. If
those systems fail or are interrupted, our processes may function at a diminished level or not at all. This could
negatively impact our ability to ship products or otherwise operate our business, and our financial results could be
harmed. For example, although it did not adversely affect our shipments, an earthquake in late December of 2006
disrupted communications with China, where a significant part of our manufacturing occurs.

We also rely upon the performance of the systems and processes of our contract manufacturers to build and
ship our products. If those systems and processes experience interruption or delay, our ability to build and ship our
products in a timely manner may be harmed. For example, as we have expanded our contract manufacturing base to
China, we have experienced instances where our contract manufacturer was not able to ship products in the time
periods expected by us. If we are not able to ship our products or if product shipments are delayed, our ability to
recognize revenue in a timely manner for those products would be affected and our financial results could be
harmed.

We are dependent on sole source and limited source suppliers for several key components, which makes
us susceptible to shortages or price fluctuations in our supply chain and we may face increased
challenges in supply chain management in the future.

With the current demand for electronic products, component shortages are possible and the predictability of
the availability of such components may be limited. Growth in our business and the economy is likely to create
greater pressures on us and our suppliers to accurately project overall component demand and to establish optimal
component levels. If shortages or delays persist, the price of these components may increase, or the components
may not be available at all. We may not be able to secure enough components at reasonable prices or of acceptable
quality to build new products in a timely manner and our revenues and gross margins could suffer until other sources
can be developed. For example, throughout the first quarter of 2006 we experienced component shortages that
resulted in delays of shipments of product until late in the quarter and in an increase in our day sales outstanding. We
currently purchase numerous key components, including ASICs, from single or limited sources. The development
of alternate sources for those components is time consuming, difficult and costly. In addition, the lead times
associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. In
the event of a component shortage or supply interruption from these suppliers, we may not be able to develop
alternate or second sources in a timely manner. If, as a result, we are unable to buy these components in quantities
sufficient to meet our requirements on a timely basis, we will not be able to deliver product to our customers, which
would seriously impact present and future sales, which would, in turn, adversely affect our business.

19

In addition, the development, licensing or acquisition of new products in the future may increase the
complexity of supply chain management. Failure to effectively manage the supply of key components and products
would adversely affect our business.

We are dependent on contract manufacturers with whom we do not have long-term supply contracts, and
changes to those relationships, expected or unexpected, may result in delays or disruptions that could
cause us to lose revenue and damage our customer relationships.

We depend on independent contract manufacturers (each of which is a third-party manufacturer for numerous
companies) to manufacture our products. Although we have contracts with our contract manufacturers, those
contracts do not require them to manufacture our products on a long-term basis in any specific quantity or at any
specific price. In addition, it is time consuming and costly to qualify and implement additional contract manu-
facturer relationships. Therefore, if we should fail to effectively manage our contract manufacturer relationships or
if one or more of them should experience delays, disruptions or quality control problems in our manufacturing
operations, or if we had to change or add additional contract manufacturers or contract manufacturing sites, our
ability to ship products to our customers could be delayed. Also, the addition of manufacturing locations or contract
manufacturers would increase the complexity of our supply chain management. Moreover, an increasing portion of
our manufacturing is performed in China and other countries and is therefore subject to risks associated with doing
business in other countries. Each of these factors could adversely affect our business and financial results.

We face intense competition that could reduce our revenues and adversely affect our financial results.

Competition is intense in the markets that we address. The IP infrastructure market has historically been
dominated by Cisco with other companies such as Alcatel-Lucent, Ericsson, Extreme Networks, Foundry
Networks, Huawei, and Nortel providing products to a smaller segment of the market. In addition, a number
of other small public and private companies have products or have announced plans for new products to address the
same challenges and market segments that our products address.

In the service layer technologies market, we face intense competition from a broader group of companies
including appliance vendors such as Cisco, Fortinet, F5 Networks, Nortel and Riverbed, and software vendors such
as CheckPoint. In addition, a number of other small public and private companies have products or have announced
plans for new products to address the same challenges that our products address.

In addition, actual or speculated consolidation among competitors, or the acquisition of our partners and
resellers by competitors, can increase the competitive pressures faced by us. In this regard, Alcatel combined with
Lucent in 2006 and Ericsson acquired Redback in 2007. A number of our competitors have substantially greater
resources and can offer a wider range of products and services for the overall network equipment market than we do.
If we are unable to compete successfully against existing and future competitors on the basis of product offerings or
price, we could experience a loss in market share and revenues and/or be required to reduce prices, which could
reduce our gross margins, and which could materially and adversely affect our business, operating results and
financial condition.

A limited number of our customers comprise a significant portion of our revenues and increases the
degree of customer concentration risk, and any decrease in revenue from these customers could have an
adverse effect on our net revenues and operating results.

A substantial majority of our net revenues depend on sales to a limited number of customers and distribution
partners. Nokia-Siemens Networks B.V. (“NSN”) and its predecessor companies contributed more than 10% of
revenue in the fiscal years ended 2007, 2006 and 2005. This customer concentration increases the risk of quarterly
fluctuations in our revenues and operating results. Any downturn in the business of our key customers or potential
new customers could significantly decrease sales to such customers, which could adversely affect our net revenues
and results of operations. In addition, there has been and continues to be consolidation in the telecommunications
industry (for example, the acquisitions of AT&T Inc., MCI, Inc. and BellSouth Corporation) and consolidation
among the large vendors of telecommunications equipment and services (for example, the combination of Alcatel
and Lucent, the joint venture of Nokia-Siemens Networks and the acquisition of Redback by Ericsson). Such

20

consolidation may cause our customers who are involved in these acquisitions to suspend or indefinitely reduce
their purchases of our products or have other unforeseen consequences that could harm our business and operating
results.

We are a party to lawsuits, which are costly to investigate and defend and, if determined adversely to us,
could require us to pay damages or prevent us from taking certain actions, any or all of which could
harm our business and financial condition.

We and certain of our current and former officers and current and former members of our board of directors are
subject to various lawsuits. For example, we have been served with lawsuits related to the alleged backdating of
stock options and other related matters, a description of which can be found in Note 8 of Notes to Consolidated
Financial Statements, under the heading “Legal Proceedings.” There can be no assurance that these or any actions
that have been or may be brought against us will be resolved in our favor. Regardless of whether they are resolved in
our favor, these lawsuits are, and any future lawsuits to which we may become a party will likely be, expensive and
time consuming to investigate, defend and/or resolve. Such costs of investigation and defense, as well as any losses
resulting from these claims, could significantly increase our expenses and adversely affect our profitability and cash
flow.

In addition, we are party to a lawsuit which seeks to enjoin us from granting equity awards under our 2006
Equity Incentive Plan (the “2006 Plan”), as well as to invalidate all awards granted under such plan to date. The
2006 Plan is the only active plan under which we currently grant stock options and restricted stock units to our
employees. If this lawsuit is resolved against us, we may be prevented from using the 2006 Plan to provide these
equity awards to recruit new employees or to compensate existing employees, which would put us at a significant
disadvantage to other companies that compete for workers in high technology industries such as ours. Accordingly,
our ability to hire, retain and motivate current and prospective employees would be harmed, the result of which
could negatively impact our business operations.

We are currently implementing upgrades to key internal IT systems, and problems with the design or
implementation of these systems could interfere with our business and operations.

We have initiated a project to upgrade certain key internal IT systems, including our company-wide human
resources management system and our enterprise resource planning (“ERP”) system. We have invested, and will
continue to invest, significant capital and human resources in the design and implementation of these systems,
which may be disruptive to our underlying business. Any disruptions or delays in the design and implementation of
the new systems, particularly any disruptions or delays that impact our operations, could adversely affect our ability
to process customer orders, ship products, provide services and support to our customers, bill and track our
customers, fulfill contractual obligations, file SEC reports in a timely manner and otherwise run our business. Even
if we do not encounter these adverse effects, the design and implementation of these new systems may be much
more costly than we anticipated. If we are unable to successfully design and implement these new systems as
planned, our financial position, results of operations and cash flows could be negatively impacted.

Litigation or claims regarding intellectual property rights may be time consuming, expensive and require
a significant amount of resources to prosecute, defend or make our products non-infringing.

Third parties have asserted and may in the future assert claims or initiate litigation related to patent, copyright,
trademark and other intellectual property rights to technologies and related standards that are relevant to our
products. The asserted claims and/or initiated litigation may include claims against us or our manufacturers,
suppliers or customers, alleging infringement of their proprietary rights with respect to our products. Regardless of
the merit of these claims, they have been and can be time-consuming, result in costly litigation and may require us to
develop non-infringing technologies or enter into license agreements. Furthermore, because of the potential for high
awards of damages or injunctive relief that are not necessarily predictable, even arguably unmeritorious claims may
be settled for significant amounts of money. If any infringement or other intellectual property claim made against us
by any third-party is successful, if we are required to settle litigation for significant amounts of money, or if we fail
to develop non-infringing technology or license required proprietary rights on commercially reasonable terms and
conditions, our business, operating results and financial condition could be materially and adversely affected.

21

We are exposed to fluctuations in currency exchange rates which could negatively affect our financial
results and cash flows.

Because a majority of our business is conducted outside the United States, we are exposed to fluctuations in
foreign currency exchange rates. These fluctuations could have a material adverse impact on our financial results
and cash flows.

Our sales and costs of revenues are primarily denominated in U.S. dollars. Our operating expenses are
denominated in U.S. dollars as well as other foreign currencies including the British Pound, the Euro, Indian Rupee,
and Japanese Yen, related to our operations outside of the United States. An increase in the value of the U.S. dollar
could increase the real cost to our customers of our products in those markets outside the United States where we sell
in U.S. dollars, and a weakened dollar could increase the cost of local operating expenses and procurement of raw
materials to the extent we must purchase components in foreign currencies. A decrease in the value of the U.S. dollar
could also increase the real cost to us of our expenses in countries outside the United States.

Currently, we hedge only those currency exposures associated with certain assets and liabilities denominated
in nonfunctional currencies and periodically will hedge anticipated foreign currency operating expenses. The
hedging activities undertaken by us are intended to partially offset the impact of currency fluctuations. If our
attempts to hedge against these risks are not successful, our net income could be adversely impacted.

We are required to expense equity compensation given to our employees, which has reduced our reported
earnings, will significantly harm our operating results in future periods and may reduce our stock price
and our ability to effectively utilize equity compensation to attract and retain employees.

We historically have used stock options and other equity awards as a significant component of our employee
compensation program in order to align employees’ interests with the interests of our stockholders, encourage
employee retention, and provide competitive compensation packages. The Financial Accounting Standards Board
has adopted changes that require companies to record a charge to earnings for employee stock option grants and
other equity incentives. We adopted this standard effective January 1, 2006. By causing us to record significantly
increased compensation costs, such accounting changes have reduced, and will continue to reduce, our reported
earnings and will significantly harm our operating results in future periods. These factors may require us to reduce
the availability and amount of equity incentives provided to employees, which may make it more difficult for us to
attract, retain and motivate key personnel. Moreover, if securities analysts, institutional investors and other investors
adopt financial models that include stock option expense in their primary analysis of our financial results, our stock
price could decline as a result of reliance on these models with higher expense calculations. Each of these results
could materially and adversely affect our business.

Matters related to the investigation into our historical stock option granting practices and the restatement
of our financial statements may result in additional litigation, regulatory proceedings and government
enforcement actions.

Our historical stock option granting practices and the restatement of our financial statements have exposed us
to greater risks associated with litigation, regulatory proceedings and government enforcement actions. For more
information regarding our current litigation and related inquiries, please see Note 8 of Notes to Consolidated
Financial Statements under the heading “Legal Proceedings” as well as the other risk factors related to litigation set
forth in this section. We have provided the results of our internal review and independent investigation to the
Securities and Exchange Commission (“SEC”) and the United States Attorney’s Office for the Northern District of
California, and in that regard we have responded to formal and informal requests for documents and additional
information. In August 2007, we announced that we entered into a settlement agreement with the SEC in connection
with our historical stock option granting practices in which we consented to a permanent injunction against any
future violations of the antifraud, reporting, books-and-records and internal control provisions of the federal
securities laws. This settlement concludes the SEC’s formal investigation of the Company with respect to this
matter. No assurance can be given regarding the outcomes from the current litigation or other possible actions
relating to our past stock option practices. The resolution of these matters will be time consuming, expensive, and
may distract management from the conduct of our business. Furthermore, if we are subject to adverse findings in

22

litigation, we could be required to pay damages or penalties or have other remedies imposed, which could harm our
business, financial condition, results of operations and cash flows.

In addition, while we believe that we have made appropriate judgments in determining the correct measure-
ment dates for our stock option grants, the SEC may disagree with the manner in which we accounted for and
reported, or did not report, the corresponding financial impact. Accordingly, there is a risk that we may have to
further restate our prior financial statements, amend prior filings with the SEC, or take other actions not currently
contemplated.

If we fail to adequately evolve our financial and managerial control and reporting systems and processes,
our ability to manage and grow our business will be negatively affected.

Our ability to successfully offer our products and implement our business plan in a rapidly evolving market
depends upon an effective planning and management process. We will need to continue to improve our financial and
managerial control and our reporting systems and procedures in order to manage our business effectively in the
future. If we fail to continue to implement improved systems and processes, our ability to manage our business and
results of operations may be negatively affected.

Our success depends upon our ability to effectively plan and manage our resources and restructure our
business through rapidly fluctuating economic and market conditions.

Our ability to successfully offer our products and services in a rapidly evolving market requires an effective
planning, forecasting, and management process to enable us to effectively scale our business and adjust our business
in response to fluctuating market opportunities and conditions. In periods of market expansion, we have increased
investment in our business by, for example, increasing headcount and increasing our investment in research and
development and other parts of our business. Conversely, during 2001 and 2002, in response to downward trending
industry and market conditions, we restructured our business and reduced our workforce. Many of our expenses,
such as real estate expenses, cannot be rapidly or easily adjusted as a result of fluctuations in our business or
numbers of employees. Moreover, rapid changes in the size of our workforce could adversely affect the ability to
develop and deliver products and services as planned or impair our ability to realize our current or future business
objectives.

Our ability to develop, market and sell products could be harmed if we are unable to retain or hire key
personnel.

Our future success depends upon our ability to recruit and retain the services of executive, engineering, sales,
marketing and support personnel. The supply of highly qualified individuals, in particular engineers in very
specialized technical areas, or sales people specializing in the service provider and enterprise markets, is limited
and competition for such individuals is intense. None of our officers or key employees is bound by an employment
agreement for any specific term. The loss of the services of any of our key employees, the inability to attract or
retain personnel in the future or delays in hiring required personnel, particularly engineers and sales people, and the
complexity and time involved in replacing or training new employees, could delay the development and intro-
duction of new products, and negatively impact our ability to market, sell or support our products.

We sell our products to customers that use those products to build networks and IP infrastructure and, if
the demand for network and IP systems does not continue to grow, then our business, operating results
and financial condition could be adversely affected.

A substantial portion of our business and revenue depends on the growth of secure IP infrastructure and on the
deployment of our products by customers that depend on the continued growth of IP services. As a result of changes
in the economy and capital spending or the building of network capacity in excess of demand, all of which have in
the past particularly affected telecommunications service providers, spending on IP infrastructure can vary, which
could have a material adverse effect on our business and financial results. In addition, a number of our existing
customers are evaluating the build out of their next generation network, or NGN. During the decision making period
when the customers are determining the design of those networks and the selection of the equipment they will use in

23

those networks, such customers may greatly reduce or suspend their spending on secure IP infrastructure. Such
pauses in purchases can make it more difficult to predict revenues from such customers, can cause fluctuations in
the level of spending by these customers and, even where our products are ultimately selected, can have a material
adverse effect on our business and financial results.

The long sales and implementation cycles for our products, as well as our expectation that some customers
will sporadically place large orders with short lead times, may cause our revenues and operating results to
vary significantly from quarter to quarter.

A customer’s decision to purchase certain of our products involves a significant commitment of its resources
and a lengthy evaluation and product qualification process. As a result, the sales cycle may be lengthy. In particular,
customers making critical decisions regarding the design and implementation of large or next-generation networks
may engage in very lengthy procurement processes that may delay or impact expected future orders. Throughout the
sales cycle, we may spend considerable time educating and providing information to prospective customers
regarding the use and benefits of our products. Even after making the decision to purchase, customers may deploy
our products slowly and deliberately. Timing of deployment can vary widely and depends on the skill set of the
customer, the size of the network deployment, the complexity of the customer’s network environment and the
degree of hardware and operating system configuration necessary to deploy the products. Customers with large
networks usually expand their networks in large increments on a periodic basis. Accordingly, we may receive
purchase orders for significant dollar amounts on an irregular basis. These long cycles, as well as our expectation
that customers will tend to sporadically place large orders with short lead times, may cause revenues and operating
results to vary significantly and unexpectedly from quarter to quarter.

Integration of past acquisitions and future acquisitions could disrupt our business and harm our financial
condition and stock price and may dilute the ownership of our stockholders.

We have made, and may continue to make, acquisitions in order to enhance our business. In 2005 we
completed the acquisitions of five private companies. Acquisitions involve numerous risks, including problems
combining the purchased operations, technologies or products, unanticipated costs, diversion of management’s
attention from our core businesses, adverse effects on existing business relationships with suppliers and customers,
risks associated with entering markets in which we have no or limited prior experience and potential loss of key
employees. There can be no assurance that we will be able to successfully integrate any businesses, products,
technologies or personnel that we might acquire. The integration of businesses that we have acquired has been, and
will continue to be, a complex, time consuming and expensive process. Acquisitions may also require us to issue
common stock that dilutes the ownership of our current stockholders, assume liabilities, record goodwill and
non-amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic
impairment charges, incur amortization expenses related to certain intangible assets, and incur large and immediate
write-offs and restructuring and other related expenses, all of which could harm our operating results and financial
condition.

In addition, if we fail in our integration efforts with respect to our acquisitions and are unable to efficiently
operate as a combined organization utilizing common information and communication systems, operating pro-
cedures, financial controls and human resources practices, our business and financial condition may be adversely
affected.

Our products are highly technical and if they contain undetected errors, our business could be adversely
affected and we might have to defend lawsuits or pay damages in connection with any alleged or actual
failure of our products and services.

Our products are highly technical and complex, are critical to the operation of many networks and, in the case
of our security products, provide and monitor network security and may protect valuable information. Our products
have contained and may contain one or more undetected errors, defects or security vulnerabilities. Some errors in
our products may only be discovered after a product has been installed and used by end customers. Any errors or
security vulnerabilities discovered in our products after commercial release could result in loss of revenues or delay
in revenue recognition, loss of customers and increased service and warranty cost, any of which could adversely

24

affect our business and results of operations. In addition, we could face claims for product liability, tort or breach of
warranty. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. In addition,
if our business liability insurance coverage is inadequate or future coverage is unavailable on acceptable terms or at
all, our financial condition could be harmed.

A breach of network security could harm public perception of our security products, which could cause
us to lose revenues.

If an actual or perceived breach of network security occurs in the network of a customer of our security
products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness
of our products could be harmed. This could cause us to lose current and potential end customers or cause us to lose
current and potential value-added resellers and distributors. Because the techniques used by computer hackers to
access or sabotage networks change frequently and generally are not recognized until launched against a target, we
may be unable to anticipate these techniques.

If our products do not interoperate with our customers’ networks, installations will be delayed or
cancelled and could harm our business.

Our products are designed to interface with our customers’ existing networks, each of which have different
specifications and utilize multiple protocol standards and products from other vendors. Many of our customers’
networks contain multiple generations of products that have been added over time as these networks have grown and
evolved. Our products will be required to interoperate with many or all of the products within these networks as well
as future products in order to meet our customers’ requirements. If we find errors in the existing software or defects
in the hardware used in our customers’ networks, we may have to modify our software or hardware to fix or
overcome these errors so that our products will interoperate and scale with the existing software and hardware,
which could be costly and negatively impact our operating results. In addition, if our products do not interoperate
with those of our customers’ networks, demand for our products could be adversely affected or orders for our
products could be cancelled. This could hurt our operating results, damage our reputation and seriously harm our
business and prospects.

Governmental regulations affecting the import or export of products could negatively affect our revenues.

The United States and various other governments have imposed controls, export license requirements and
restrictions on the import or export of some technologies, especially encryption technology. In addition, from time
to time, governmental agencies have proposed additional regulation of encryption technology, such as requiring the
escrow and governmental recovery of private encryption keys. Governmental regulation of encryption technology
and regulation of imports or exports, or our failure to obtain required import or export approval for our products,
could harm our international and domestic sales and adversely affect our revenues.

Due to the global nature of our operations, economic or social conditions or changes in a particular
country or region could adversely affect our sales or increase our costs and expenses, which could have a
material adverse impact on our financial condition.

We conduct significant sales and customer support operations directly and indirectly through our distributors
and value-added resellers in countries throughout the world and also depend on the operations of our contract
manufacturers and suppliers that are located inside and outside of the United States. In addition, our research and
development operations are conducted in the United States as well as other countries. Our future results could be
materially adversely affected by a variety of uncontrollable and changing factors including, among others, political
or social unrest, natural disasters, epidemic disease, war, or economic instability in a specific country or region,
trade protection measures and other regulatory requirements which may affect our ability to import or export our
products from various countries, service provider and government spending patterns affected by political consid-
erations and difficulties in staffing and managing international operations. Any or all of these factors could have a
material adverse impact on our revenue, costs, expenses, results of operations and financial condition.

25

Our products incorporate and rely upon licensed third-party technology and if licenses of third-party
technology do not continue to be available to us or become very expensive, our revenues and ability to
develop and introduce new products could be adversely affected.

We integrate licensed third-party technology into certain of our products. From time to time, we may be
required to license additional technology from third parties to develop new products or product enhancements.
Third-party licenses may not be available or continue to be available to us on commercially reasonable terms. Our
inability to maintain or re-license any third-party licenses required in our products or our inability to obtain
third-party licenses necessary to develop new products and product enhancements, could require us to obtain
substitute technology of lower quality or performance standards or at a greater cost, any of which could harm our
business, financial condition and results of operations.

We are subject to risks arising from our international operations.

We derive a majority of our revenues from our international operations, and we plan to continue expanding our
business in international markets in the future. As a result of our international operations, we are affected by
economic, regulatory and political conditions in foreign countries, including changes in IT spending generally, the
imposition of government controls, changes or limitations in trade protection laws, unfavorable changes in tax
treaties or laws, natural disasters, labor unrest, earnings expatriation restrictions, misappropriation of intellectual
property, acts of terrorism and continued unrest in many regions and other factors, which could have a material
impact on our international revenues and operations. In particular, in some countries we may experience reduced
intellectual property protection. Moreover, local laws and customs in many countries differ significantly from those
in the United States. In many foreign countries, particularly in those with developing economies, it is common for
others to engage in business practices that are prohibited by our internal policies and procedures or United States
regulations applicable to us. Although we implement policies and procedures designed to ensure compliance with
these laws and policies, there can be no assurance that all of our employees, contractors and agents will not take
actions in violations of them. Violations of laws or key control policies by our employees, contractors or agents
could result in financial reporting problems, fines, penalties, or prohibition on the importation or exportation of our
products and could have a material adverse effect on our business.

While we believe that we currently have adequate internal control over financial reporting, we are
exposed to risks from legislation requiring companies to evaluate those internal controls.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to report on, and our independent
auditors to attest to, the effectiveness of our internal control over financial reporting. We have an ongoing program
to perform the system and process evaluation and testing necessary to comply with these requirements. We have and
will continue to incur significant expenses and devote management resources to Section 404 compliance on an
ongoing basis. In the event that our chief executive officer, chief financial officer or independent registered public
accounting firm determine in the future that our internal controls over financial reporting are not effective as defined
under Section 404, investor perceptions may be adversely affected and could cause a decline in the market price of
our stock.

Regulation of the telecommunications industry could harm our operating results and future prospects.

The telecommunications industry is highly regulated and our business and financial condition could be
adversely affected by changes in the regulations relating to the telecommunications industry. Currently, there are
few laws or regulations that apply directly to access to or commerce on IP networks. We could be adversely affected
by regulation of IP networks and commerce in any country where we operate. Such regulations could address
matters such as voice over the Internet or using Internet Protocol, encryption technology, and access charges for
service providers. In addition, regulations have been adopted with respect to environmental matters, such as the
Waste Electrical and Electronic Equipment (“WEEE”) and Restriction of the Use of Certain Hazardous Substances
in Electrical and Electronic Equipment (“RoHS”) regulations adopted by the European Union, as well as
regulations prohibiting government entities from purchasing security products that do not meet specified local
certification criteria. Compliance with such regulations may be costly and time-consuming for us and our suppliers
and partners. The adoption and implementation of such regulations could decrease demand for our products, and at

26

the same time could increase the cost of building and selling our products as well as impact our ability to ship
products into affected areas and recognize revenue in a timely manner, which could have a material adverse effect
on our business, operating results and financial condition.

Our reported financial results could suffer if there is an additional impairment of goodwill or other
intangible assets with indefinite lives.

We are required to annually test, and review on an interim basis, our goodwill and intangible assets with
indefinite lives, including the goodwill associated with past acquisitions and any future acquisitions, to determine if
impairment has occurred. If such assets are deemed impaired, an impairment loss equal to the amount by which the
carrying amount exceeds the fair value of the assets would be recognized. This would result in incremental expenses
for that quarter which would reduce any earnings or increase any loss for the period in which the impairment was
determined to have occurred. For example, such impairment could occur if the market value of our common stock
falls below certain levels for a sustained period or if the portions of our business related to companies we have
acquired fail to grow at expected rates or decline. In the second quarter of 2006, this impairment evaluation resulted
in a reduction of $1,280.0 million to the carrying value of goodwill on our balance sheet for the SLT segment,
primarily due to the decline in our market capitalization that occurred over a period of approximately nine months
prior to the impairment review and, to a lesser extent, a decrease in the forecasted future cash flows used in the
income approach. Declines in our stock prices in the future as well as any marked decline in our level of revenues or
gross margins increase the risk that goodwill and intangible assets may become impaired in future periods. We
cannot accurately predict the amount and timing of any impairment of assets.

Changes in effective tax rates or adverse outcomes resulting from examination of our income or other
tax returns could adversely affect our results.

Our future effective tax rates could be subject to volatility or adversely affected by earnings being lower than
anticipated in countries where we have lower statutory rates and higher than anticipated earnings in countries where
we have higher statutory rates; by changes in the valuation of our deferred tax assets and liabilities; by expiration of
or lapses in the R&D tax credit laws; by transfer pricing adjustments related to certain acquisitions including the
license of acquired intangibles under our intercompany R&D cost sharing arrangement; by tax effects of stock-
based compensation; by costs related to intercompany restructurings; or by changes in tax laws, regulations,
accounting principles, or interpretations thereof. In addition, we are subject to the continuous examination of our
income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of
adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.
There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on
our operating results and financial condition.

The investment of our cash balance and our investments in government and corporate debt securities are
subject to risks which may cause losses and affect the liquidity of these investments.

At December 31, 2007, we had $1,716.1 million in cash and cash equivalents and $291.1 million in
investments in government and corporate debt securities. We have invested these amounts in U.S. government
securities, corporate notes and bonds, commercial paper, and money market funds meeting certain criteria. Certain
of these investments are subject to general credit, liquidity, market and interest rate risks, which may be exacerbated
by U.S. sub-prime mortgage defaults that have affected various sectors of the financial markets and caused credit
and liquidity issues. These market risks associated with our investment portfolio may have a negative adverse effect
on our results of operations, liquidity and financial condition.

Uninsured losses could harm our operating results.

We self-insure against many business risks and expenses, such as intellectual property litigation and our
medical benefit programs, where we believe we can adequately self-insure against the anticipated exposure and risk
or where insurance is either not deemed cost-effective or is not available. We also maintain a program of insurance
coverage for various types of property, casualty, and other risks. We place our insurance coverage with various
carriers in numerous jurisdictions. The types and amounts of insurance that we obtain vary from time to time and

27

from location to location, depending on availability, cost, and our decisions with respect to risk retention. The
policies are subject to deductibles, policy limits and exclusions that result in our retention of a level of risk on a self-
insurance basis. Losses not covered by insurance could be substantial and unpredictable and could adversely affect
our results of operations.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Annual Report on Form 10-K (“Report”), including the “Management’s Discussion and Analysis of
Financial Condition and Results of Operations”, contains forward-looking statements regarding future events and
the future results of our Company that are based on current expectations, estimates, forecasts, and projections about
the industry in which we operate and the beliefs and assumptions of our management. Words such as ‘expects,’
‘anticipates,’ ‘targets,’ ‘goals,’ ‘projects,’ ‘intends,’ ‘plans,’ ‘believes,’ ‘seeks,’ ‘estimates,’ variations of such words,
and similar expressions are intended to identify such forward-looking statements. These forward-looking statements
are only predictions and are subject to risks, uncertainties and assumptions that are difficult to predict. Therefore,
actual results may differ materially and adversely from those expressed in any forward-looking statements. Factors
that might cause or contribute to such differences include, but are not limited to, those discussed in this Report
under the section entitled “Risk Factors” in Item 1A of Part I and elsewhere, and in other reports we file with the
Securities and Exchange Commission (“SEC”), specifically the most recent reports on Form 10-Q. We undertake no
obligation to revise or update publicly any forward-looking statements for any reason.

The following discussion is based upon our Consolidated Financial Statements included elsewhere in this
report, which have been prepared in accordance with accounting principles generally accepted in the United States.
The preparation of these financial statements requires us to make estimates and judgments that affect the reported
amounts of assets, liabilities, revenues and expenses, and related disclosure of contingencies. In the course of
operating our business, we routinely make decisions as to the timing of the payment of invoices, the collection of
receivables, the manufacturing and shipment of products, the fulfillment of orders, the purchase of supplies, and the
building of inventory and spare parts, among other matters. Each of these decisions has some impact on the financial
results for any given period. In making these decisions, we consider various factors including contractual
obligations, customer satisfaction, competition, internal and external financial targets and expectations, and
financial planning objectives. On an on-going basis, we evaluate our estimates, including those related to sales
returns, pricing credits, warranty costs, allowance for doubtful accounts, impairment of long-term assets, especially
goodwill and intangible assets, contract manufacturer exposures for carrying and obsolete material charges,
assumptions used in the valuation of stock-based compensation, and litigation. We base our estimates on historical
experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of
which form the basis for making judgments about the carrying values of assets and liabilities that are not readily
apparent from other sources. Actual results may differ from these estimates under different assumptions or
conditions.

To aid in understanding our operating results for the periods covered by this report, we have provided an
executive overview and a summary of the significant events that affected the most recent fiscal year and a discussion
of the nature of our operating expenses. These sections should be read in conjunction with the more detailed
discussion and analysis of our financial condition and results of operations in this Item 7, our “Risk Factors” section
included in Item 1A of Part I, and our audited consolidated financial statements and notes included in Item 8 of
Part II of this report.

Executive Overview

Our 2007 performance was the result of a combination of strong market demand for networking and security
products as well as our focused execution and market share gains. In addition, we began shipment of several new
products which contributed to our revenue growth during the year. During 2007, we also implemented a series of
operational excellence initiatives. These initiatives are intended to strengthen the management systems and
processes throughout our organization to support our growth.

• Net Revenues: Net revenue increased $532.5 million, or 23%, to $2,836.1 million in 2007, compared to
2006. We experienced growth in both product and service revenues, which represented 82.0% and 18.0% of
our total net revenue in 2007. Product revenue increased $433.7 million, or 23%, to $2,327.0 million in 2007,
compared to the year-ago period. Service revenue increased $98.8 million, or 24%, to $509.1 million in
2007, compared to 2006. Infrastructure product, SLT product and Service revenues represented 61.8%,
20.2% and 18.0% of our total net revenues, respectively, for 2007. Our revenue performance and share gains
were driven by Infrastructure product and SLT product sales. Infrastructure product revenue increased
$339.8 million, or 24%, in 2007 as compared to 2006 primarily attributable to revenue growth in our M- and
T-series routers, as well as our recently introduced MX-series routers. SLT product revenue increased in
2007 as compared to 2006 primarily attributable to the increased sales of our firewall virtual private network
(“Firewall”) products, including our recently introduced SSG320M and SSG350M firewall appliances, and
to a lesser extent, increases in secure socket layer virtual private network (“SSL”), J-series, and WAN
Optimization products. Service revenue increased in 2007 over the prior year primarily due to the increase in
our installed base of equipment under service contracts and, to a lesser extent, growth in professional service
revenue.

New Infrastructure products shipped in 2007 include the T1600 router and our MX-series product family.
Our T1600 product is a high-capacity and energy-efficient core router. Our MX-series family of Ethernet
Service Routers enables service providers to deliver advance services including IPTVand video-on-demand
at scale. The MX-series includes MX960, a large capacity and high-density Carrier Ethernet platform, and
MX480, which began shipping in the fourth quarter of 2007.

New SLT products introduced in 2007 include the SSG320M and SSG350M products, which are purpose-
built appliances that deliver high performance and secure connectivity for regional and branch office. We
also introduced new products within the J-series service router family, such as J2320 and J2350, which are
designed to enable enterprises to accelerate the secure delivery of business critical applications across their
networks. Additionally, we continued to make enhancements and design updates to other SLT product
families during 2007.

From a geographical perspective, net revenues grew across the Americas, Europe, Middle East and Africa
(“EMEA”) and Asia Pacific (“APAC”) regions.

• Operating Margin: Operating income increased $1,404.9 million to $407.1 million in 2007, compared to
an operating loss of $997.8 million in 2006. Operating margin was 14.4% in 2007 as compared to -43.3% in
2006. The increase in operating margin was primarily attributable to decreases in operating expenses as a
percentage of net revenue. Such decreases were largely due to the goodwill and intangible impairment
charges of $1,283.4 million in 2006 and the absence of such charges in 2007. Additionally, to a lesser extent,
operating margin improved due to the decrease in sales and marketing expenses as a percentage of net
revenue as well as decreases in other charges associated with our internal stock option investigation, partially
offset by increases in research and development expenses in 2007 as compared to 2006.

• Net Income and Net Income Per Share: Net income was $360.8 million, or $0.62 per share on a diluted
basis, in 2007, compared to a net loss of $1,001.4 million, or $1.76 per share on a diluted basis, in 2006. The
increases in 2007 were primarily attributable to the goodwill and intangible impairment charges of
$1,283.4 million in 2006 that were absent in 2007 as well as the revenue growth and an increase in
operating margin as discussed above.

• Other Financial Highlights: We used $1,623.2 million to repurchase 69.4 million shares of our common
stock in 2007. Cash used in our stock repurchases was offset by cash flows from operating activities,
investing activities and common stock issued to our employees in connection with our equity incentive plans
of $786.5 million, $571.8 million, and $355.0 million, respectively, in 2007.

Significant Events

Business and Market Environment

In 2007, we benefited from the continued progress by our service provider customers in the build-out of Next
Generation Networks (“NGN”) designed to support a fast and cost-effective deployment of multiple types of
services (“multi-play services”), such as voice, data, and video, that enable our customers to develop new sources of
revenue and profitability. We maintained a strong position in the Infrastructure product business and gained share in
key market segments. We also experienced an increased interest in our SLT portfolio due to increased network
demand from our enterprise customers as well as growth from service providers using our SLT products for both
managed service offerings and outsourced solutions for their customers. Additionally, we continued our momentum
in the enterprise market for our SLT products as well as routing products portfolio. We now serve over 95 of the
Fortune 100 companies and more than 30,000 enterprise customers worldwide. In addition, over 45 out of the
50 state governments in the United States have deployed our technologies.

We believe our innovation and market momentum have enabled us to maintain relationships with our partners,
including strategic resellers Alcatel-Lucent, Ericsson, Inc., and Nokia-Siemens Networks B.V. (“NSN”), while
developing broader relationships with technology leaders such as International Business Machines Corporation
(“IBM”) and Microsoft Corporation to better serve our customers.

Stock Repurchase Activity

We repurchased and retired 69.4 million common shares, at an average price of $23.37 per share for a total of
$1,623.2 million as part of our $2.0 billion common stock repurchase program approved by our Board in July 2006
and February 2007 (the “2006 Stock Repurchase Program”). As of December 31, 2007, our 2006 Stock Repurchase
Program had a remaining authorization of $376.8 million for repurchases. See Note 15 in Item 8 for discussion of
our stock repurchase activity in 2008.

Stock Option Investigation and Amendment of Certain Stock Options

In 2007, we completed the restatement of our historical financial statements as a result of our independent
stock option investigation and review of historical stock compensation practices. In addition, we regained
compliance with listing standards of the NASDAQ Global Select Market. We recorded $6.0 million in operating

33

expenses during 2007 in connection with this stock option investigation, compared to $20.5 million and nil in 2006
and 2005, respectively.

In April 2007, we completed a tender offer to amend certain options granted under the Juniper Networks, Inc.
Amended & Restated 1996 Stock Plan and the Juniper Networks, Inc. 2000 Nonstatutory Stock Option Plan that had
original exercise prices per share that were less than the fair market value per share of the common stock underlying
the option on the option’s grant date, as determined by us for financial accounting purposes. Under this tender offer,
employees subject to taxation in the United States and Canada had the opportunity to increase their strike price on
affected options to the appropriate fair market value per share on the date of grant so as to avoid unfavorable tax
consequences under United States Internal Revenue Code Section 409A (“409A issue”) or Canadian tax laws and
regulations. In exchange for increasing the strike price of these options, we committed to make a cash payment to
employees participating in the offer so as to make these employees whole for the incremental strike price as
compared to their original option exercise price. In connection with the offer, we amended options to purchase
4.3 million shares of our common stock in 2007 and made aggregate cash payments of $7.6 million to offer
participants in January 2008. We accrued this aggregate payment liability and recognized an operating expense for
the corresponding amount during 2007.

Settlement with the Securities and Exchange Commission

On August 28, 2007, we announced that the Commissioners of the SEC authorized the settlement between us
and the SEC regarding the previously disclosed SEC inquiry into our historical stock option granting practices.
Without admitting or denying the allegations in the SEC’s complaint, we agreed to settle the charges by consenting
to a permanent injunction against any future violations of the antifraud, reporting, books-and-records and internal
control provisions of the federal securities laws. No monetary penalties were assessed against us in conjunction with
this settlement. This settlement concludes the SEC’s formal investigation of the company with respect to our
historical stock option granting practices.

Adoption of FIN 48

We adopted Financial Accounting Standards Board (“FASB”) Interpretation No. 48, Accounting for Uncer-
tainty in Income Taxes, (“FIN 48”) on January 1, 2007, the first day of fiscal 2007. Under FIN 48, an entity may only
recognize or continue to recognize tax positions that meet a “more likely than not” threshold. The cumulative effect
of applying FIN 48 was a $19.2 million increase to the opening balance of accumulated deficit as of January 1, 2007
and a $1.0 million increase to goodwill.

As of the date of adoption, the total amount of gross unrecognized tax benefits was $85.2 million, of which

$70.8 million, if recognized, would affect our effective tax rate.

In accordance with our accounting policy, we recognize accrued interest and penalties related to unrecognized
tax benefits as a component of tax expense in the consolidated statement of operations. This policy did not change as
a result of the adoption of FIN 48. We accrued interest expense and penalties of $4.1 million within other long-term
liabilities in the consolidated balance sheets as of the date of adoption.

We conduct business globally and, as a result, we or one or more of our subsidiaries file income tax returns in
the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are
subject to examination by taxing authorities throughout the world, including such major jurisdictions as Ireland,
Hong Kong, U.K., France, Germany, The Netherlands, Japan, China, Australia, and the U.S. With few exceptions,
we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2003,
although carryforward attributes that were generated prior to 2003 may still be adjusted upon examination by the
IRS if the attributes either have been or will be used in a future period.

34

Nature of Expenses

Most of our manufacturing, repair and supply chain operations are outsourced to independent contract
manufacturers. Accordingly, most of our cost of revenues consists of payments to our independent contract
manufacturers for the standard product costs. The independent contract manufacturers produce our products using
design specifications, quality assurance programs and standards that we establish. Controls around manufacturing,
engineering and documentation are conducted at our facilities in Sunnyvale, California and Westford, Massachusetts.
Our independent contract manufacturers have facilities primarily in Canada, China, Malaysia, and the United States.
We generally do not own the components and title to products transfers from the contract manufacturers to us and
immediately to our customers upon shipment.

The contract manufacturers procure components based on our build forecasts and if actual component usage is
lower than our forecasts, we may be, and have been in the past, liable for carrying or obsolete material charges.

We have employees in our manufacturing and operations organization who manage relationships with our

contract manufacturers, manage our supply chain, and monitor product testing and quality.

Employee related costs have historically been the primary driver of our operating expenses and we expect this
trend to continue. Employee related costs include items such as wages, commissions, bonuses, vacation, benefits,
stock-based compensation and travel. We had 5,879, 4,833, and 4,145 employees as of December 31, 2007, 2006,
and 2005, respectively. The year-over-year increases were primarily attributable to increases in our research and
development, sales and customer service activities. Our headcount is expected to increase in 2008 as we continue to
expand these functions. We accounted for stock-based compensation under the fair value approach of FAS 123R in
2007 and 2006. In 2005, we accounted for stock-based compensation under the intrinsic value approach of APB 25.
Details of our stock-based compensation expense are described in Note 1 and Note 9 in Notes to Consolidated
Financial Statements of this Form 10-K.

Facility and information technology departmental costs are allocated to other departments based on headcount.
These departmental costs have increased in 2007 and 2006 due to increases in headcount and facility leases
resulting from infrastructure systems added to support our growth and past acquisitions. Facility and information
technology related headcount was 224, 177, and 168 as of December 31, 2007, 2006, and 2005, respectively. In
2008, we expect to further invest in our company-wide information technology infrastructure as we implement our
operational excellence initiatives.

Our operating expenses are denominated in U.S. dollars as well as other foreign currencies including the
British Pound, the Euro, Indian Rupee, and Japanese Yen. Changes in related currency exchange rates may affect
our operating results. Periodically, we use foreign currency forward and/or option contracts to hedge certain
forecasted foreign currency transactions relating to operating expenses. The effective portion of the derivative’s
gain or loss is initially reported as a component of accumulated other comprehensive income and, upon occurrence
of the forecasted transaction, is subsequently reclassified into the consolidated statements of operations line item to
which the hedged transaction relates. Any ineffectiveness of the hedging instruments is reported in other income
(expense) on our consolidated statements of operations. The increase in operating expenses including research and
development, sales and marketing, as well as general and administrative expenses, due to foreign currency
fluctuations, net of hedging, was approximately 2% in 2007.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with U.S. generally accepted accounting principles
requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of
the financial statements and the reported amounts of net revenue and expenses in the reporting period. We regularly
evaluate our estimates and assumptions. We base our estimates and assumptions on current facts, historical
experience and various other factors that we believe to be reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent
from other sources. The actual results experienced by us may differ materially and adversely from management’s
estimates. To the extent there are material differences between our estimates and the actual results, our future results
of operations will be affected.

35

We believe the following critical accounting policies require us to make significant judgments and estimates in

the preparation of our consolidated financial statements:

• Revenue Recognition. Our products are integrated with software that is essential to the functionality of our
equipment. Additionally, we provide unspecified upgrades and enhancements related to our integrated
software through our maintenance contracts for most of our products. Accordingly, we account for revenue
in accordance with Statement of Position No. 97-2, Software Revenue Recognition, and all related
interpretations. We recognize revenue when persuasive evidence of an arrangement exists, delivery or
performance has occurred, the sales price is fixed or determinable and collectibility is reasonably assured.
Evidence of an arrangement generally consists of customer purchase orders and, in certain instances, sales
contracts or agreements. Shipping terms and related documents, or written evidence of customer acceptance,
when applicable, are used to verify delivery or performance. In instances where we have outstanding
obligations related to product delivery or the final acceptance of the product, revenue is deferred until all the
delivery and acceptance criteria have been met. We assess whether the sales price is fixed or determinable
based on payment terms and whether the sales price is subject to refund or adjustment. We assess
collectibility based on the creditworthiness of the customer as determined by credit checks and the
customer’s payment history to us. Accounts receivable are recorded net of allowance for doubtful accounts,
estimated customer returns and pricing credits.

For arrangements with multiple elements, such as sales of products that include services, we allocate
revenue to each element using the residual method based on vendor specific objective evidence of fair value
of the undelivered items. Under the residual method, the amount of revenue allocated to delivered elements
equals the total arrangement consideration less the aggregate fair value of any undelivered elements. Vendor
specific objective evidence of fair value is based on the price charged when the element is sold separately.
We then recognize revenue on each deliverable in accordance with our policies for product and service
revenue recognition. If vendor specific objective evidence of fair value of one or more undelivered items
does not exist, revenue is deferred and recognized at the earlier of (i) delivery of those elements or (ii) when
fair value can be established unless maintenance is the only undelivered element, in which case, the entire
arrangement fee is recognized ratably over the contractual support period. Our ability to recognize revenue
in the future may be affected if actual selling prices are significantly less than fair value. In addition, our
ability to recognize revenue in the future could be impacted by conditions imposed by our customers.

For sales to direct end-users and value-added resellers, we recognize product revenue upon transfer of title
and risk of loss, which is generally upon shipment. It is our practice to identify an end-user prior to shipment
to a value-added reseller. For our end-users and value-added resellers, there are no significant obligations for
future performance such as rights of return or pricing credits. A portion of our sales are made through
distributors under agreements allowing for pricing credits and/or rights of return. We recognize product
revenue on sales made through these distributors upon sell-through as reported to us by the distributors.
Deferred revenue on shipments to distributors reflects the effects of distributor pricing credits and the
amount of gross margin expected to be realized upon sell-through. Deferred revenue is recorded net of the
related product costs of revenue.

We record reductions to revenue for estimated product returns and pricing adjustments, such as rebates and
price protection, in the same period that the related revenue is recorded. The amount of these reductions is
based on historical sales returns and price protection credits, specific criteria included in rebate agreements,
and other factors known at the time. Additional reductions to revenue would result if actual product returns
or pricing adjustments exceed our estimates. In addition, we report revenue net of sales taxes.

Services include maintenance, training and professional services. Maintenance is offered under renewable
contracts. Revenue from maintenance service contracts is deferred and is recognized ratably over the
contractual support period, which is generally one to three years. Revenue from training and professional
services is recognized as the services are completed or ratably over the contractual period, which is
generally one year or less.

We sell certain interests in accounts receivables as part of a distributor accounts receivable financing
arrangement which was established by us with a major financing company. Accounts receivables sold under

36

this arrangement in advance of revenue recognition are accounted for as debt and were $10.0 million and nil
as of December 31, 2007 and 2006, respectively.

• Contract Manufacturer Liabilities. We outsource most of our manufacturing, repair and supply chain
management operations to our independent contract manufacturers and a significant portion of our cost of
revenues consists of payments to them. Our independent contract manufacturers procure components and
manufacture our products based on our demand forecasts. These forecasts are based on our estimates of
future demand for our products, which are in turn based on historical trends and an analysis from our sales
and marketing organizations, adjusted for overall market conditions. We establish reserves for carrying
charges and obsolete material charges for excess components purchased based on historical trends. If the
actual component usage and product demand are significantly lower than forecasted, which may be caused
by factors outside of our control, we have contractual liabilities and exposures with the independent contract
manufacturers, such as carrying costs and obsolete material exposures, which would have an adverse impact
on our gross margins and profitability.

• Warranty Reserve. We generally offer a one-year warranty on all of our hardware products and a 90-day
warranty on the media that contains the software embedded in the products. We establish reserves for
estimated product warranty costs at the time revenue is recognized. Although we engage in extensive
product quality programs and processes, our warranty obligation is affected by product failure rates, use of
materials and technical labor costs and associated overhead incurred in correcting any product failure.
Should actual product failure rates, use of materials or service delivery costs differ from our estimates,
additional warranty reserves could be required, which could reduce gross margins.

• Goodwill and Purchased Intangible Assets. Goodwill is recorded as the difference, if any, between the
aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets
acquired. The amounts and useful lives assigned to other intangible assets impact the amount and timing of
future amortization, and the amount assigned to in-process research and development is expensed imme-
diately. The value of our intangible assets, including goodwill, could be impacted by future adverse changes
such as: (i) future declines in our operating results, (ii) a decline in the valuation of technology company
stocks, including the valuation of our common stock, (iii) significant slowdown in the worldwide economy
or the networking industry or (iv) failure to meet the performance projections included in our forecasts of
future operating results. We evaluate these assets on an annual basis as of November 1 or more frequently if
we believe indicators of impairment exist. In the process of our annual impairment review, we use the market
approach as well as the income approach methodology of valuation that includes the discounted cash flow
method to determine the fair value of our intangible assets. Significant management judgment is required in
the forecasts of future operating results that are used in the discounted cash flow method of valuation. The
estimates we have used are consistent with the plans and estimates that we use to manage our business. It is
possible, however, that the plans and estimates used may be incorrect. If our actual results, or the plans and
estimates used in future impairment analyses, are lower than the original estimates used to assess the
recoverability of these assets, we could incur additional impairment charges.

• Stock-Based Compensation. We account for stock-based compensation in accordance with FAS No. 123R
beginning in 2006. Under the provisions of Statement of Financial Accounting Standards No. 123 (revised
2004), Share-Based Payment (“FAS 123R”), stock-based compensation cost is estimated at the grant date
based on the award’s fair value as calculated by the Black-Scholes-Merton (“BSM”) option-pricing model
and is recognized as expense ratably over the requisite service period. The BSM model requires various
highly subjective assumptions including volatility, forfeiture rates, and expected option life. If any of the
assumptions used in the BSM model change significantly, stock-based compensation expense may differ
materially in the future from that recorded in the current period. In conjunction with the adoption of
FAS 123R, we also adopted the single-approach method for valuing our stock-based awards as well as the
straight-line method for amortizing the related stock-based compensation expense under the modified
prospective approach. Prior to the adoption of FAS 123R, we accounted for stock-based compensation under
the intrinsic value recognition provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees
(“APB 25”).

• Income Taxes. Estimates and judgments occur in the calculation of certain tax liabilities and in the
determination of the recoverability of certain deferred tax assets, which arise from temporary differences
and carry-forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that
apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled.
We regularly assess the likelihood that our deferred tax assets will be realized from recoverable income taxes
or recovered from future taxable income based on the realization criteria set forth under FAS 109,
Accounting for Income Taxes, and record a valuation allowance to reduce our deferred tax assets to the
amount that we believe to be more likely than not realizable. We believe it is more likely than not that
forecasted income together with the tax effects of the deferred tax liabilities will be sufficient to fully recover
the remaining deferred tax assets. In the event that all or part of the net deferred tax assets are determined not
to be realizable in the future, an adjustment to the valuation allowance would be charged to earnings in the
period such determination is made. Similarly, if we subsequently realize deferred tax assets that were
previously determined to be unrealizable, the respective valuation allowance would be reversed, resulting in
a positive adjustment to earnings or a decrease in goodwill in the period such determination is made. In
addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of
complex tax regulations. We recognize potential liabilities based on our estimate of whether, and the extent
to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the
reversal of the liabilities may result in tax benefits being recognized in the period when we determine the
liabilities are no longer necessary. If our estimate of tax liabilities is less than the amount ultimately assessed,
a further charge to expense would result.

On January 1, 2007, we adopted FIN 48. FIN 48 is an interpretation of FASB Statement 109, Accounting for
Income Taxes, and it seeks to reduce the diversity in practice associated with certain aspects of measurement
and recognition in accounting for income taxes. FIN 48 prescribes a recognition threshold and measurement
attribute for the financial statement recognition and measurement of a tax position that an entity takes or
expects to take in a tax return. Additionally, FIN 48 provides guidance on de-recognition, classification,
interest and penalties, accounting in interim periods, disclosures and transition. Under FIN 48, an entity may
only recognize or continue to recognize tax positions that meet a “more likely than not” threshold. In
addition, the application of FIN 48 may increase an entity’s future effective tax rates and its future intra-
period effective tax rate volatility. Our cumulative effect of applying FIN 48 was a $19.2 million increase to
the opening balance of accumulated deficit as of January 1, 2007 and a $1.0 million increase to goodwill.

• Loss Contingencies. We are subject to the possibility of various loss contingencies arising in the ordinary
course of business. We consider the likelihood of loss or impairment of an asset or the incurrence of a
liability, as well as our ability to reasonably estimate the amount of loss, in determining loss contingencies.
An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has
been incurred and the amount of loss can be reasonably estimated. We regularly evaluate current information
available to us to determine whether such accruals should be adjusted and whether new accruals are required.
In addition, from time to time, we are involved in disputes, litigation and other legal actions. We are
aggressively defending our current litigation matters; however, there are many uncertainties associated with
any litigation, and these actions or other third party claims against us may cause us to incur costly litigation
and/or substantial settlement charges. In addition, the resolution of any future intellectual property litigation
may require us to make royalty payments, which could adversely impact gross margins in future periods. If
any of those events were to occur, our business, financial condition and results of operations and cash flows
could be materially and adversely affected. We record a charge equal to at least the minimum estimated
liability for litigation costs or a loss contingency only when both of the following conditions are met:
(i) information available prior to issuance of the financial statements indicates that it is probable that an asset
had been impaired or a liability had been incurred at the date of the financial statements and (ii) the range of
loss can be reasonably estimated. However, the actual liability in any such litigation may be materially
different from our estimates, which could result in the need to record additional expenses.

Our total net revenues increased $532.5 million, or 23% to $2,836.1 million in 2007 as compared to 2006. Our
total net revenues increased $239.6 million, or 12% to $2,303.6 million in 2006 as compared to 2005. The increases
in both years were primarily due to the demand growth in the markets we serve. In addition, we gained market share
in several areas and capitalized on the opportunities in our targeted markets with our new and existing product and
service offerings during 2007.

Net Product Revenues

Our net product revenue increased $433.7 million, or 23%, from 2006 to $2,327.0 million in 2007. The
increase was the result of increased activity in both Infrastructure product and SLT product sales to service provider
and enterprise markets. In particular we had success in selling our products to customers who are adopting NGN IP
networks, which are designed to reduce total operating costs and to be able to offer multiple services over a single
network. In addition, we had a number of new product releases and expanded into new emerging markets during
2007. Net product revenue grew $122.3 million, or 7% from 2005 to 2006, the majority of which was generated
from our SLT product revenue growth in 2006.

Infrastructure Product Revenues

Infrastructure product revenues accounted for $1,753.2 million, or 61.8%, of total net revenues, and increased
$339.8 million, or 24%, in 2007, compared to 2006. We benefited from the strong worldwide demand for high-
performance router products as our service provider customers seek simplified, scalable network infrastructures across
fiber, cable and mobile access technologies to support increasing performance demands on their networks. The
Infrastructure product revenue increase in 2007 was primarily attributable to increased revenue from our M-, T-, and

39

MX-series router products driven by our service provider customers’ continued build out of NGN as their bandwidth
requirement increases. Our service provider customers also moved towards NGNs designed to enable a fast and cost-
effective deployment of differentiating multi-play services that allow them to generate new sources of revenue. Also
contributing to the revenue growth was an increase in Infrastructure product sales to the content service provider and
the enterprise markets. From a geographical perspective, we experienced strength in the Americas region. We also
experienced revenue increases in APAC and EMEA.

Infrastructure products accounted for $1,413.4 million, or 61.4%, of our total net revenues during 2006 and
$1,371.6 million, or 66.5%, of our total net revenues during 2005. Infrastructure product net revenue grew by
$41.8 million, or 3%, from 2005 to 2006 primarily due to continued success from a very significant year of growth
in 2005, which strengthened our position as a supplier to the largest service providers in the world, particularly in
the Americas and in EMEA. We experienced revenue growth in higher-end infrastructure chassis products and
increased penetration by our core and edge router portfolio as service providers acquired products for their NGNs
and multi-play service offerings. This growth was partially offset by a pause in the build out of NGNs and associated
purchase decisions, particularly in Japan, as major carriers prepare for the next stage of bandwidth and services
expansion, and a large product revenue deferral as of December 31, 2006 for products shipped to one of our largest
customers.

We track Infrastructure chassis revenue units recognized and ports shipped to analyze customer trends and
indicate areas of potential network growth. Our Infrastructure product platforms are essentially modular, with the
chassis serving as the base of the platform. Each chassis has a certain number of slots that are available to be
populated with components we refer to as modules or interfaces. The modules are the components through which
the router receives incoming packets of data from a variety of transmission media. The physical connection between
a transmission medium and a module is referred to as a port. The number of ports on a module varies widely
depending on the functionality and throughput offered by the module. Chassis revenue units represent the number of
chassis on which revenue was recognized during the period. The following table shows infrastructure revenue units
recognized and ports shipped:

Chassis revenue units increased 10% from 2006 to 2007 as our customers expanded the capacity in their
existing networks. The increase was mainly due to the introduction of the MX-series products, which are our Carrier
Ethernet base routers. We also experienced growth in our M- and T-series products, driven by bandwidth demand as
service provider customers sought to expand voice and video capability in their existing networks. Port shipment
units increased by 41% in 2007 as compared to 2006. The increase was associated with the growth in chassis
revenue units with larger expansion capacity and the customers’ need to differentiate themselves by providing
feature-rich multi-play services.

Chassis revenue units slightly increased from 2005 to 2006 due primarily to the sales of higher-end T-series
and M-series products and the inclusion of the chassis units related to a 2005 acquisition, partially offset by
decreases in sales of lower-end E-series and M-series products. Sales of higher-end chassis units increased as our
customers continued to adopt and expand IP networks in order to reduce total operating costs and to be able to offer
multiple services over a single network. Port shipment units increased from 2005 to 2006 primarily due to the
increase in port demands driven by the larger expansion capacity in the higher-end chassis revenue units shipped
during 2006, partially offset by the lower port capacity in the CTP-series chassis revenue units.

SLT Product Revenues

SLT product revenues accounted for 20.2% of total net revenues and increased $93.9 million, or 20%, to
$573.8 million in 2007, compared to 2006. The revenue increase was due to sales increases across the majority of
the SLT product families particularly the Firewall, SSL, WAN Optimization and J-series products. Our customers’

40

demands for SLT products grew due to their increasing focus on addressing the risks associated with connecting and
delivering critical network services and business applications. The integrated systems introduced prior to 2007,
such as the ISG and SSG firewall products, gained traction in the market place and generated additional revenue in
2007. The revenue increase from our SSL products was due to our deployments of SSL solutions to enterprises and
governments who were seeking to enhance their remote access to data and applications. We experienced
considerable improvement in revenue from our WAN Optimization application acceleration platforms as customers
sought to boost the responsiveness of their networks. All three geographic regions had significant growth in SLT
sales during 2007. We experienced a growing demand for our SLT products in both the enterprise and service
provider markets as we focused on cross-selling more integrated products and solutions in the enterprise and service
provider markets while leveraging partnerships with open standards based interoperability of our SLT products. In
addition, we benefited from typical fourth-quarter seasonality. We generally experienced seasonality and fluctu-
ations in the demand for our SLT products, which may result in greater variations in our quarterly revenue.

In January 2008, we announced a plan to phase out our DX product line. These products will be supported until
2013. We do not expect this plan to have a material impact on our consolidated results of operations, cash flows, and
financial condition.

SLT products accounted for $479.9 million, or 20.8%, of our total net revenues in 2006 and $399.4 million, or
19.3%, of total net revenues during 2005. SLT product net revenue increased $80.5 million, or 20%, from 2005 to
2006 due to a growing demand and brand recognition for our SLT products from large enterprises and the
U.S. Federal Government. Sales increased across various SLT product families including Firewalls, IDP, J-series,
DX, and SSL. In addition, the new products announced in 2006 and the DX and application acceleration products
added to our portfolio through the various acquisitions in 2005 contributed to this increase. In addition, we
experienced success in cross-selling SLT products to service providers for both their own IT infrastructure and
resale built upon the acquisitions we completed in 2005. A further part of the increase was due to successfully
selling to much larger enterprise customers with increased footprint and complexity.

SLT product units increased in 2007 as compared to 2006 primarily attributable to the growing demand for our
SLT products in the market place. The 30% increase in the number of SLT units was greater than the revenue
increase of 20% primarily due to the increased revenue from sales of our branch firewall products, which have lower
average selling price than other SLT products. SLT product units increased 8% while SLT product revenue
increased 20% in 2006 as compared to 2005 primarily due to sales of high-end firewalls.

Net Service Revenues

Net service revenues increased $98.8 million, or 24%, to $509.1 million in 2007, compared to 2006, and
represent 18.0% of net revenues. The growth in service revenue was primarily driven by increased technical support
service contracts associated with higher Infrastructure and SLT product sales, which have resulted in increased
renewals and a larger installed base of equipment being serviced. Installed base is calculated by each customer
based on the number of systems that the customers has under maintenance. A majority of our service revenue is
earned from customers who purchase our products and enter into maintenance contracts that are generally for one-
year renewable periods. We also have multi-year maintenance contracts. These contracts are typically for services
such as 24-hour customer support, non-specified updates and hardware repairs. We recognize revenue from service
contracts as the services are completed or ratably over the period of the obligation. In addition to support services
and professional services, we also provide educational services. Consistent with 2006, support service revenues
represents 89% of net service revenues in 2007. To a lesser extent, professional services also contributed to the
growth in net service revenues in 2007. Professional service revenue increased primarily due to large customer
deployments requiring consulting services.

41

Net service revenues increased $117.3 million, or 40%, from 2005 to 2006 primarily due to the growth in
support services driven by an increase in the installed base that we are servicing, as well as increased attach rates on
new product sales, improved enterprise service infrastructure allowing more rapid implementation of services and
the addition of new professional service offerings. Professional service revenue also increased, to a lesser extent, in
2006 compared to 2005 due primarily to maintenance-related on-site engineering services as well as additional
consulting projects in 2006.

* Prior year information has been reclassified to conform to the current period presentation.

We continue to experience varying distribution of revenue among our three geographic regions for the three

years ended December 31, 2007 and we expect this trend to continue.

Net revenues in the Americas region increased $307.2 million, or 30%, to $1,340.5 million in 2007 as
compared to 2006. The Americas region represented 47.3% of net revenues in 2007, an increase of 2.5 percentage
points over 2006. The increases were largely due to strength in the United States and in Latin America. Net revenue
from the United States increased $265.5 million in 2007 compared to 2006, primarily due to revenue growth in the
Infrastructure product segment from our service provider and internet content provider customers and, to a lesser
extent, SLT product and Service segments. Net revenues from Latin America increased $39.1 million in 2007,
compared to 2006, primarily due to strength in Brazil driven by sales to a major local carrier. Total 2006 revenue
recorded by the Americas region grew by $100.4 million from its 2005 level and remained at approximately 45% of
worldwide revenue, as compared to 2005, due to significant success in the United States and with the main service
providers in Canada and various South American countries including Brazil and Argentina. Net revenue in the
United States increased by $71.3 million in 2006 from 2005 due to continued success both with enterprise
customers such as the U.S. Federal Government, as well as with major service providers in the United States. The
increase was also due in part to sales to major internet content providers and cable providers. This success was
partially offset by a significant product revenue deferral for products shipped to one of our largest customers. Net
revenue in Americas as a percentage of total net revenue decreased slightly in 2006 compared to 2005 as a result of
the strong growth in EMEA.

Net revenue in the EMEA region increased $100.6 million, or 12%, to $918.0 million in 2007, compared to
2006, due to increased Infrastructure product and SLT product revenues along with increased service revenue driven
by strong bandwidth demands in the region. Revenue increased in Belgium, Ireland, United Kingdom, and France,

42

partially offset by a decrease in the Netherlands as well as revenue growth in the emerging markets such as Eastern
Europe and the Middle East. Net revenue from EMEA as a percentage of net revenues decreased 3.1 percentage
points to 32.4% in 2007 over 2006 primarily due to relative strength in the Americas region. Revenue in the EMEA
region grew by $207.3 million, or 34%, in 2006, compared to 2005, due to significant success with NGN
deployments across the region, in particular Sweden, the Netherlands, France, and Germany, as well as sales growth
in emerging regions including Russia, Eastern Europe and the Middle East. As a result, net revenue from EMEA as a
percentage of net revenues increased 5.9 percentage points to 35.5% in 2006 over 2005.

Net revenue in the Asia Pacific region increased $124.7 million, or 28%, to $577.6 million in 2007, compared
to 2006, due to increased revenue from Infrastructure products, SLT products and Service driven by demands from
service providers as well as enterprise customers resulting from cross-selling of our product portfolio. We
experienced revenue growth across the region with strength in Korea, Australia, Malaysia, India and Indonesia.
Revenue from the Asia Pacific region declined $68.1 million, or 13%, in 2006 as compared to 2005 primarily due to
the impact of certain NGN project decision delays in Japan driving revenue down year over year, partially offset by
increased demands in China.

NSN accounted for greater than 10% of our net product and service revenues for the years ended December 31,
2007, 2006, and 2005. We expect that our largest customers, as well as key strategic partners, will continue to
account for a substantial portion of our net revenues in 2008.

Cost of Product Revenues

Product gross margin improved from 70.7% in 2006 to 70.9% in 2007. The slight increase in product gross
margin was mainly due to favorable product mix and, to a lesser extent, improvements in standard costs of our
Infrastructure products, partially offset by a slight decrease in our SLT product gross margin. The improvement of
standard costs as a percentage of product revenue was primarily due to our increased purchases from contract
manufacturers and suppliers in lower cost regions. As of December 31, 2007 and 2006, we employed 190 and
149 people, respectively, in our manufacturing and operations organization. These personnel manage relationships
with our contract manufacturers, manage our supply chain, and monitor product testing and quality.

Infrastructure product gross margin percentages improved slightly in 2007 compared to 2006. Our Infra-
structure chassis revenue units increased 10% while our Infrastructure ports shipped increased 41% during 2007, on
a year-over-year basis, compared to the Infrastructure product revenues increase of 24% for the year. We
experienced a favorable product mix and derived a larger portion of revenues from richly configured high-end
M-series and T-series router products. We also generated revenues from high-margin port shipments, which are add-
on components to the chassis routers. The increases in chassis units and port shipments were driven by bandwidth
demand as customers are seeking to expand capabilities in their networks and to offer differentiating feature-rich
multi-play services that allow them to generate new revenue sources. See further details in the “Infrastructure
Product Revenues” section.

43

The gross margin improvement from Infrastructure products was offset by a slight decrease in our SLT product
gross margin in 2007. The decrease in SLT product gross margin was primarily due to product mix, particularly
from an increase in the mix of lower margin branch Firewall and J-series products in 2007. In addition, higher
manufacturing costs associated with newer and more complex products were also impacting SLT gross margin. The
higher manufacturing costs were partially offset as we realized the benefit of our cost-reduction efforts of moving
more manufacturing to lower cost regions. See further details in the “SLT Product Revenues” section.

Cost of product revenues increased $48.8 million, or 10%, in 2006 as compared to 2005. The increase was
primarily attributable to increased product revenue in both the enterprise and service provider markets. Net product
gross margin of 70.7% for 2006 slightly decreased, compared to 71.4% for 2005, primarily due to the impact of the
mix of products and the mix of territories, partially offset by reduced manufacturing costs. As of December 31, 2006
and 2005, we employed 149 and 134 people, respectively, in our manufacturing and operations organization. The
increase in stock compensation expense in cost of product revenue from 2005 to 2006 of $0.9 million was primarily
due to the impact of adopting FAS 123R on January 1, 2006.

Product gross margins tend to fluctuate due to changes in the mix of products sold and our gross margins may
be impacted as we introduce new products and manage production costs among multiple contract manufacturers or
when our customers change the timing of their purchases. We will continue to seek reductions in our production
costs as we enter into new markets, including markets with different pricing structures and cost structures. Our
margins are impacted by changes in distribution channels and price competition as well as changes in the
geographic mix of our sales. Sales discounts, warranty costs, changes in shipment volume, loss of cost savings due
to changes in component pricing also impact gross margins. These factors, combined with how well we execute on
our strategy and operating plans, may lead to margin variability.

Cost of service revenues increased $52.2 million, or 26%, to $251.4 million in 2007 as compared to 2006.
Service gross margin decreased by less than one percentage point to 50.6% in 2007 as compared to 2006. The
increase in service costs and the decrease in gross margin were primarily attributable to increases in headcount
related expenses associated with expanding our service delivery infrastructure and professional service organi-
zation, particularly in North America and in India, as well as increasing our resources for supporting network build-
outs and deployments by our customers. Service related headcount increased by 137 employees, or 22%, to
748 employees in 2007, compared to 611 in 2006. Employee salary and related expenses, including stock-based
compensation expense, represented the majority of the increases in cost of service revenues in 2007. Total employee
salary and related expenses as a percentage of service revenues were approximately 25% for 2007 and 20% for
2006. Outside service expense increased as we used outside providers to support the increase in customer support
contracts and professional engagements. Freight related expense increased due to the deployment of spare parts in
supporting our growth overseas. Facility and IT expenses allocation to the cost of service revenues increased in
2007, which is consistent with other areas of our organization, due to our headcount growth and investment in
internal infrastructure to support our growing business. Partially offsetting the increases was a decrease in spares
expense due to the large spares purchase we made in 2006.

Cost of service revenues increased $52.0 million, or 35%, to $199.2 million in 2006 as compared to 2005. The
increase was a direct result of a larger installed base of products covered by service contracts. However, our service
gross margin increased one percentage point from 2005 to 2006 as a result of improved efficiencies and economies
of scale, which result in a better leveraged service organization. Total employee salary and related expenses as a
percentage of service revenue were approximately 20% for 2006 and 20% for 2005; however, in absolute dollars,
employee salary and related expenses increased from 2005 to 2006 primarily due to an investment in new customer
service personnel, particularly to support our enterprise customers. Stock compensation expense in cost of service
revenue also increased from 2005 to 2006 primarily due to the impact of adopting FAS 123R in 2006. In addition to
personnel expenses, outside services costs increased from 2005 to 2006 primarily due to contracting for engineers to
provide professional services revenue, particularly for the Middle East and other emerging markets. Spares and
freight costs increased from 2005 to 2006 due to a significant investment in spares around the world to support the
increase in customer contracts, particularly in the enterprise market. Finally, the costs associated with facilities,

44

depreciation and other expenses allocated to cost of service revenue increased from 2005 to 2006 due to increases in
revenue and investment in infrastructure to support the growing business.

Research and Development Expenses

Research and development expenses include:

• the costs of developing our products from components to prototypes to finished products,

• the costs for outside services such as certifications of new products, and

• expenditures associated with equipment used for testing.

Several components of our research and development effort require significant expenditures, such as the
development of new components and the purchase of prototype equipment, the timing of which can cause quarterly
variability in our expenses. We expense our research and development costs as they are incurred.

Research and development expense increased $142.7 million, or 30%, and increased 1.2 percentage points of
net revenues in 2007 over 2006. The increase was largely due to our commitment to continue innovation of our

45

products. In particular in 2007, we continued the development of our Ethernet products, including the MX-series
and our new EX-series Ethernet switching products introduced in January 2008, as well as the development of our
new T1600 product, which was released in November 2007. Personnel related expenses, which comprise the
majority of our research and development expenses, increased primarily due to headcount growth and merit-based
salary increases in 2007. Research and development related headcount increased by 493 employees, or 24%, in
2007 to 2,563 employees as of December 31, 2007. Headcount increase was primarily due to additional hires in the
engineering organization within the Infrastructure segment. In addition to personnel related expenses, we also
increased prototype and lab equipment expenses in 2007 for the development of our new products. Additionally our
allocated facilities and information technology, as well as depreciation expenses, for our research and development
organization increased in 2007 due to increases in headcount from additional internal systems to support our
growth. In general, we grew our engineering organizations to support product innovation, expand and improve our
product portfolio and address growth opportunities in NGN bandwidth and features for our service provider and
enterprise customers.

Research and development expenses increased $123.0 million, or 3.5 percentage points of net revenues, in
2006 over 2005 as a result of our focus on the development of a broader portfolio of networking products. The
increase in absolute dollars was primarily due to increases in personnel related expenses, depreciation, facility
related expenses, engineering and testing expenses, outside service expenses and equipment related expenses. The
increases in personnel related expenses in 2006 were primarily due to additional hires in the engineering
organization across the Infrastructure and SLT segments. Headcount increased 19% from 1,736 individuals to
2,070 individuals during 2006. The headcount increase was attributable to product innovation efforts in areas
including router security and integration in order to capture potential future NGN infrastructure growth and other
opportunities in the enterprise and the service provider markets. To a lesser extent, the increases in personnel
expenses were attributable to merit-based salary increases beginning in April 2006. Facility, engineering and testing
expense increased in 2006 to support our product innovation efforts. Outside service expenses increased in 2006
primarily due to additional consulting projects on developing future product roadmaps. The increase in stock
compensation expense in research and development expenses from 2005 to 2006 of $24.0 million was primarily due
to the impact of adopting FAS 123R in 2006. Our investment and expansion on our global research and development
efforts were primarily in China and India.

We plan to increase our investment in research and development during 2008, compared to 2007, to further
advance our competitive advantage. As a percentage of net revenues, we anticipate our research and development
spending will decrease slightly in 2008.

Sales and Marketing Expenses

Sales and marketing expenses include costs for promoting our products and services, demonstration equipment
and advertisements. These costs vary quarter-to-quarter depending on revenues, product launches and marketing
initiatives. We have an extensive distribution channel in place that we use to target new customers and increase
sales. We have made substantial investments in our distribution channel during 2007, 2006 and 2005.

Sales and marketing expenses increased $108.7 million, or 19%, to $666.7 million and represented 23.5% of
total net revenues in 2007, compared to 24.2% in 2006. As a percentage of net revenue, sales and marketing
expenses decreased slightly in 2007 due to our focus on increasing our operating margin and the efficiency of our
sales activities. The increases in absolute dollars were primarily headcount related increases. Sales and marketing
related headcount increased 272 employees, or 17%, in 2007 to 1,863 as of December 31, 2007 as we hired
additional personnel across our Infrastructure and SLT organizations to support the larger product portfolio and to
expand our presence in the enterprise marketplace. In addition, commission expenses increased primarily as a result
of strong revenue growth. In 2007, we also increased consulting expenses to support our sales and marketing
initiatives. Likewise our need and expenses for demonstration equipment has grown as we seek to capture new
markets and release new products. As the sales and marketing organization grows, we have also grown our
information technology and facilities to these organizations, accounting for the increases of related expense
allocations in 2007 over 2006.

46

Sales and marketing expenses increased $116.4 million, or 26%, to $558.0 million in 2006 compared to 2005
and increased as a percent of total net revenues. The increases were primarily due to increases in personnel related
expenses, facility related expenses, travel expenses, marketing related activities, and equipment related expenses.
Personnel related expenses increased in 2006 primarily due to additional hires to support the expansion of our
distribution channels and customer base, as well as to support the larger portfolio of products. In particular, we
expanded our enterprise sales force, and targeted key growth areas such as China, the Middle East and India. We
added 171 individuals to our sales and marketing function during 2006. Travel expense increased in 2006 due
primarily to increased headcount and more activity in emerging markets. Marketing related activities increased
primarily as a result of specific activities designed to expand and improve our brand recognition, support of our
distribution channels, introduction of new products, targeted solution value propositions and increase awareness of
our existing products to a broader range of customers. Equipment related expenses increased in 2006 due to the
introduction of new products. The increase in stock compensation expenses in sales and marketing from 2005 to
2006 of $24.5 million was primarily due to the impact of adopting FAS 123R in 2006.

We plan to continue our investment in sales and marketing activities in both direct and channel sales as well as
our service provider and enterprise focus. We anticipate our sales and marketing expenses to increase in absolute
dollars but decrease as a percentage of net revenues in 2008.

General and Administrative Expenses

General and administrative expenses include professional fees, bad debt provisions and other corporate

expenses. Professional fees include legal, audit, tax, accounting and certain corporate strategic services.

General and administrative expenses increased $19.3 million, or 20%, and represented 4.1% of total net
revenues in 2007, compared to 4.2% in 2006. As a percentage of net revenue, general and administrative expenses
slightly decreased in 2007 due to our focus on increasing our operating margin. The increases in absolute dollars
were primarily due to increases in personnel related expenses and outside professional services. Employee related
expenses, including salaries, bonuses, stock-based compensation, and fringe benefits expenses, increased in 2007
over 2006, as headcount increased by 56 employees, or 24%, in 2007 to 291 employees as of December 31, 2007.
The headcount increases were primarily in the finance and human resources organizations as we expanded our
organization infrastructure in lower cost regions, improved internal processes and continued our initiatives to
update our information systems. Outside services increased $4.5 million in 2007, compared to 2006, as we invested
in designing a more efficient organizational structure and improving our internal systems. Such increases were
offset by the decreases in accounting and legal fees of $1.5 million for 2007, compared to 2006. Consistent with
other areas of our organization, facilities and information technology allocations increased in order to support these
initiatives and the growth of our business.

General and administrative expenses increased $22.1 million, or 29%, in 2006 compared to 2005. As a
percentage of net revenues, general and administrative expenses increased slightly from 3.6% in 2005 to 4.2% in
2006. The increases were driven by increases in personnel related expenses and other related expenses. General and
administrative world-wide headcount increased 11%, or 24 individuals, during 2006, to support the overall growth
in the business. Bad debt expense increased in 2006 primarily due to a bad debt expense benefit in 2005. Facility and
IT related allocation expense increased as a result of our personnel growth and development of our systems
infrastructure. The increase of general and administrative related stock compensation expense from 2005 to 2006 of
$11.8 million was primarily due to the impact of adopting FAS 123R in 2006.

We anticipate our general and administrative expenses to increase in absolute dollars but decrease as a

percentage of net revenues in 2008.

Amortization of Purchased Intangible Assets

Amortization of purchased intangible assets decreased $5.9 million due to purchased intangible assets
reaching the end of the amortization period during 2007 as compared to 2006. Amortization of purchased
intangible assets increased $6.6 million in 2006, compared to 2005, as a result of recognizing a full year of
amortization associated with the five acquisitions completed in 2005. See Note 3 in Item 8 for more information on
our purchased intangible assets.

47

Impairment of Goodwill and Purchased Intangible Assets

We had no impairment against our goodwill or intangible assets in 2007. Impairment charges increased by
$1,277.5 million in 2006, compared to 2005, as a result of the impairment of both goodwill and purchased intangible
assets during 2006. Due primarily to the decline in the Company’s market capitalization that occurred over a period
of approximately six months prior to the impairment review and, to a lesser extent, to a decrease in the forecasted
future cash flows used in the income approach, we evaluated the carrying value of our goodwill and reduced the
goodwill within the SLT segment by $1,280.0 million. In addition, we recorded a $3.4 million impairment expense
pertaining to a write-down of intangible assets as a result of a decrease in forecasted revenue for the SBC stand-
alone products during the second quarter of 2006. In 2005, we wrote down $5.9 million of purchased intangible
assets acquired from Kagoor Networks, Inc. (“Kagoor”). See Note 3 in Item 8 for more information on our
impairment of goodwill and purchased intangible assets.

In-Process Research and Development

We had no in-process research and development (“IPR&D”) charges in 2007 and 2006. In 2005, a total of
$11.0 million was charged to IPR&D expense in connection with three of our five acquisitions during the year. Of
the total Funk purchase price, $5.3 million was allocated to IPR&D. Of the total Peribit purchase price, $3.8 million
was allocated to IPR&D. Of the total Kagoor purchase price, $1.9 million was allocated to IPR&D. None of the
Acorn Packet Solutions, Inc. (“Acorn”) or Redline Networks, Inc. (“Redline”) purchase prices were allocated to
IPR&D.

Projects that qualify as IPR&D represent those that have not yet reached technological feasibility and which
have no alternative future use. Technological feasibility is defined as being equivalent to a beta-phase working
prototype in which there is no remaining risk relating to the development. At the time of acquisition, Funk, Peribit,
and Kagoor had multiple IPR&D efforts under way for certain current and future product lines.

• For Funk, these efforts included development of new versions for the Steel-Belted Radius (“SBR”), SBR
High Availability (“HA”), and Mobile IP Module (“MIM”) II products — all related to the Radius product
offering. IPR&D as of the acquisition date also included development of new versions for Endpoint
Assurance, Proxy (Remote Control), and Odyssey product families. At the time of the Funk acquisition, it
was estimated that these development efforts would be completed over the next four months at an estimated
cost of approximately $0.9 million. These development efforts had been completed as of December 31,
2007.

• For Peribit, these efforts included the development of next versions of software for the Sequence Reducer
(“SR”) family, Sequence Mirror (“SM”) family, the Central Management System (“CMS”) products, as well
as a hardware program for both the SR and SM families. At the time of the Peribit acquisition, it was
estimated that these development efforts would be completed over the next twelve months at an estimated
cost of approximately $2.3 million. These development efforts had been completed as of December 31,
2007.

• For Kagoor, these efforts included a variety of signaling protocols and next generation products and
operating systems. At the time of the Kagoor acquisition, it was estimated that these development efforts
would be completed over the next eight months at an estimated cost of approximately $0.8 million. These
development efforts had been completed as of December 31, 2007.

Other Charges, Net

Other charges are summarized as follows:

• Restructuring and Acquisition Related Reserves.

In 2007, we recorded net restructuring and acquisition
related charges of $0.7 million, of which $1.1 million pertained to bonus accruals associated with past
acquisitions, partially offset by a benefit of $0.4 million pertaining to net restructuring adjustments. We
recorded net restructuring and acquisition related bonus expenses of $5.9 million in 2006, of which
$5.6 million was due to bonus accruals associated with the Funk and Acorn acquisitions and $0.3 million
was due to net restructuring related charges, including $0.7 million in restructuring charges associated with

48

the initiation of a restructuring plan which focused on some product development costs reductions and the
discontinuation of our SBC product. The $6.5 million restructuring and acquisition related benefit in 2005
primarily consisted of $6.9 million in adjustments related to our restructuring accrual when we re-occupied a
portion of the former NetScreen facility that was previously included in this acquisition related restructuring
reserve, partially offset by a $0.3 million bonus and earn-out accrual related to the Funk and Acorn
acquisitions.

• Stock Option Investigation Costs. We recorded expenses of $6.0 million and $20.5 million in 2007 and
2006, respectively, relating to professional fees and other costs in connection with our stock option
investigation. There were no such charges in 2005.

• Stock Option Amendment and Tax Related Charges. We recorded $8.0 million and $10.1 million in
operating expense during 2007 and 2006, respectively, in relation to the amendment of stock options and to
the payment of certain taxes and penalties associated with stock option exercises by employees. There were
no such charges in 2005.

• Net Settlement Gain. We recognized a net legal settlement gain of $5.3 million in 2007 in connection with
cash settlement proceeds of $6.2 million, net of the $0.9 million legal expense related to direct transaction
costs incurred in the third quarter of 2007.

Interest and Other Income, Net

Net interest and other income decreased $3.9 million, or 4%, in 2007 compared to 2006. This decrease was due
to decreases in interest income resulting from a lower cash, cash equivalents and investment balance attributable to
our funding of our repurchase of approximately $1.6 billion of our common stock during the first and second
quarters of 2007. Partially offsetting the decreases was the higher interest yield combined with a higher average
cash, cash equivalents and investment balances particularly in the beginning of 2007, primarily due to higher
positive cash flows from operations compared to 2006. Interest and other expenses slightly increased in 2007
compared to 2006, primarily due to costs associated with our distributor financing program. Other interest and
expenses include short-term debt expenses, debt issuance cost amortization, foreign exchange losses and other
expenses such as bank fees.

Net interest and other income increased $45.5 million in 2006 compared to 2005 primarily due to a
$45.8 million increase in interest income from 2005 to 2006 as a result of higher cash, cash equivalents and
investment balances and an increase in rates of return realized from our investments throughout 2006. Also, interest
and other expense decreased $0.3 million from 2005 and 2006 primarily due to lower portfolio management fees.

49

Gain on and (Write-Down of) Investments, Net

In June 2007, one of the companies in which we had a minority equity investment completed an initial public
offering (“IPO”). As a result, we realized a gain of $6.7 million during 2007 based upon the difference between the
market value of our investment at the time of the IPO and our cost basis. During 2006, none of our investments had
any gain or loss. In 2005, we recorded a gain of $1.7 million in connection with a business combination transaction
of a privately held company in our investment portfolio. Our cost basis of this equity investment was $1.0 million.
We have certain minority equity investments in privately held companies that are carried at cost, adjusted for any
impairment, as we do not have a controlling interest and do not have the ability to exercise significant influence over
these companies. In addition, during 2005, we wrote-down these investments by $0.4 million for changes in market
value that we believed were other-than-temporary.

Income Tax Provision

Provision for income taxes increased to $149.8 million in 2007 from $104.4 million in 2006. The 2007
effective rate was 29.3% and differs from the federal statutory rate of 35.0% primarily due to the benefit of income
in foreign jurisdictions which is subject to lower rates and research and development credits in the United States.

Provision for income taxes decreased to $104.4 million in 2006 from $146.8 million in 2005. The 2006
effective rate was (11.6%) and differs from the federal statutory rate of 35.0% primarily due to the inability to
benefit from a substantial portion of the goodwill impairment charge recorded in 2006. The 2005 effective rate was
29.5% and differs from the federal statutory rate of 35.0% due primarily to the benefit of tax credits, income in
foreign jurisdictions taxed at lower rates and a reduction in deferred tax liabilities related to the repatriation in 2005
of $225.0 million under the American Jobs Creation Act of 2004.

The gross unrecognized tax benefits increased by approximately $9.5 million for 2007, of which $8.4 million,
if recognized, would affect the effective tax rate. Interest and penalties accrued for the same period were
approximately $1.7 million.

It is reasonably possible that the amount of the liability for unrecognized tax benefits may change within the
next 12 months due to audit examinations. However, an estimate of the range of possible change cannot be made at
this time due to the high uncertainty of the resolution of and/or closure on open audits.

We are currently under examination by the IRS for the 2004 tax year and by the German tax authorities for the
2005 tax year. Additionally, we have not reached a final resolution with the IRS on an adjustment it proposed for the
1999 and 2000 tax years. We are not under examination by any other major jurisdictions in which the Company files
its income tax returns as of December 31, 2007. It is possible that the amount of the liability for unrecognized tax
benefits may change within the next 12 months. However, an estimate of the range of possible change cannot be
made at this time. We have provided for uncertain tax positions that require a FIN 48 liability.

Additional details related to our income tax provision can be found in Note 13 of Notes to the Consolidated

Financial Statements.

Segment Information

A description of the products and services for each segment can be found in Note 11 to the Consolidated
Financial Statements. We began to track financial information by our three segments in 2005 as our management
structure and responsibilities began to measure the business based on management operating income (loss). A
description of the measures included in management operating income (loss) can also be found in Note 11 to the
Consolidated Financial Statements. We have included segment financial data for each of the three years in the
period ended December 31, 2007 for comparative purposes.

Infrastructure Operating Segment

An analysis of the change in revenue for the Infrastructure segment, and the change in units, can be found

above in the section titled “Net Revenues.”

Infrastructure management operating income increased $74.6 million, or 18%, from 2006 to $495.5 million in
2007 due to revenue growth outpacing expense growth. Our increase in revenue was partially offset by our
continued investments in research and development efforts as we seek to continue our innovation of products and
expand our Infrastructure product portfolio. We also allocate sales and marketing, general and administrative, as
well as facility and information technology expenses to the Infrastructure segment generally based on headcount
and revenue. In 2007, our sales and marketing expenses decreased slightly as a percentage of net revenues but
increased in absolute dollars as we increased our efforts to reach enterprise and service provider customers. We will
continue to make these investments to expand our product features and functionality based upon the trends in the
market place.

Infrastructure management operating income decreased $68.3 million, or 14%, from 2005 to $420.9 million in
2006 primarily due to higher personnel related costs associated with our investments in product innovation for next
generation core and edge infrastructure products as well as increased operating expenses associated with marketing
related efforts and improvements to our internal infrastructure, partially offset by savings in sales expense during
2006 as we increasingly leveraged our existing distribution channel.

SLT Operating Segment

An analysis of the change in revenue for the SLT segment, and the change in units, can be found in the section

titled “Net Revenues.”

52

SLT management operating loss increased $7.0 million, or 62%, from 2006 to $18.3 million in 2007 due to
product mix and increases in manufacturing related costs. The loss was primarily due to our effort to build a
foundation to help enable future SLT revenue growth and due to slight decreases in the SLT product gross margins.
The increase in SLT operating expenses was due in large part to our increased allocated expenses to the SLT
segment from both information technology investments and the higher variable compensation expenses associated
with company-wide revenue growth. Additionally, we strategically invested in our research and development efforts
to develop technologies and products for the JUNOS platform. In an effort to control costs, we have moved a
significant portion of the SLT development organization to lower cost regions while expanding our product
portfolio. SLT management operating loss was also impacted by continued investments in our sales and distribution
channels. We allocate sales and marketing, general and administrative, as well as facility and information
technology expenses to the SLT segment generally based on revenue and headcount. In the third quarter of
2007, we increased our allocation of such expenses to the SLT segment, compared to the same period in 2006,
primarily due to information technology investments and the higher variable compensation expenses associated
with company-wide revenue increases. SLT gross margin decreased slightly in 2007, as compared to 2006, due to
higher manufacturing costs associated with newer and more complex products. Such higher manufacturing costs
were partially offset as we realized the benefit of our cost-reduction efforts of moving more manufacturing to lower
cost regions. The increases in SLT operating expenses were partially offset by our revenue growth especially in the
fourth quarter of 2007 due to customers’ demands for security products, particularly Firewall, and due to typical
quarterly seasonality. We generally experienced quarterly seasonality and fluctuations in the demand for our SLT
products, particularly in the fourth quarter, which may result in greater variations in our quarterly operating results.

The SLT segment incurred a management operating loss of $11.3 million in 2006, compared to the
management operating income of $10.4 million in 2005, due primarily to higher product and personnel related
costs, partially offset by higher SLT net revenues and gross margin. Increases in personnel related costs were
primarily related to headcount growth in order to support product innovation, new products sales and a larger
customer base. We made a strategic decision to invest more into the enterprise and SLT markets to drive increased
revenues and SLT productivity in the future.

Service Operating Segment

An analysis of the change in revenue for the Service segment can be found above in the section titled “Net

Revenue.”

Service management operating income increased $24.9 million, or 25%, from 2006 to $126.4 million in 2007
by achieving economies of scale and cost control initiatives. Revenue growth surpassed cost of service expense
growth in 2007 primarily due to our growth in installed base of equipment being serviced. We also increased our
service offerings and customer service infrastructure. Our Service gross margin slightly decreased from 2006 to
2007 as we increased our headcount to build our global customer service and professional service organizations. We
expanded our customer service center in both North America and India as well as increased our resources for
supporting network build-outs and deployments by our customers. Service management operating income was also
impacted by sales and marketing, general and administrative expenses as well as facilities and information systems
management allocations to the service segment.

Service gross margin percentages as well as Service management operating income increased from 2005 to
2006 due primarily to improved economies of scale achieved by faster revenue growth through the Infrastructure
products and the SLT products relative to the increases in operating costs. In absolute dollars, employee related
expenses increased in 2006 as a result of increased service related headcount from 476 to 611 individuals. Expenses
associated with spare components also increased in 2006 to support increased demands driven by additional service
contracts as a result of our growing installed base.

Stock-Based Compensation and Related Payroll Taxes

Stock-based compensation expense increased by $0.4 million in 2007 as compared to 2006. The increase was
primarily attributable to new stock options and RSU grants, partially offset by the lower stock option expense in
2007 as a result of the acceleration of the vesting of certain unvested and “out-of-the-money” stock options

53

completed in December 2005 (“2005 stock option vesting acceleration”). Stock-based compensation related payroll
tax expense increased $5.0 million in 2007. These expenses represent employment taxes we incurred in connection
with our employee stock programs. Changes in such expenses are primarily attributable to the timing of the stock
options exercises by our employees. We experienced a considerable increase in these expenses due to the increase in
our share price occurring in 2007. In contrast, we had restrictions on stock option exercises during 2006.

Stock-based compensation expense increased by $65.3 million in 2006 as compared to 2005 primarily due to
the adoption of FAS 123R. Stock-based compensation related payroll tax expense decreased $0.2 million in 2006,
compared to 2005 primarily due to restrictions on stock option exercises in 2006 as a result of our delayed periodic
filings with the SEC.

In-Process Research and Development

There were no IPR&D charges in 2007 and 2006. We recognized IPR&D charges of $11.0 million 2005 in

connection with the acquisitions completed during the year.

Restructuring Charges in Cost of Product Revenues

There was no restructuring charges included in cost of product revenues during 2007 and 2005. We recognized
restructuring charges in cost of product revenues of $1.4 million for 2006 in connection with the restructuring plan
implemented during the year.

The significant components of our working capital are cash and cash equivalents, short-term investments and

accounts receivable, reduced by accounts payable, accrued liabilities, debt and deferred revenue.

Working capital decreased $583.9 million from December 31, 2006 to December 31, 2007 primarily due to the
decrease in cash, cash equivalents, and available-for-sale investments balance in the first and second quarters of
2007. Our total cash, cash equivalents, and available-for-sale investments decreased by $598.5 million during 2007
primarily due to stock repurchases under the 2006 Stock Repurchase Program discussed below. Additionally,
because the debt related to our outstanding zero-coupon convertible notes is due within one year, we reclassified
$399.5 million of debt underlying such notes from long-term to short-term liabilities and, as a result, further reduced
our working capital. In 2007, we generated $786.5 million of cash from operations and $571.8 million from our
investing activities. In addition, we received financing cash flows of $355.0 million from common stock issued to
our employees through stock option exercises and employee stock purchase plan purchases. In 2007, we
repurchased 69.4 million shares of our common stock for $1,623.2 million at an average purchase price of
$23.37 per share. As of December 31, 2007, our 2006 Stock Repurchase Program had remaining authorized funds of
$376.8 million. We may repurchase additional shares opportunistically under this program, subject to a review of
circumstances at the time. See Note 15 in Item 8 for discussion of our stock repurchase activity in 2008.

In June 2007, we entered into a senior secured margin lending agreement with a third-party financial institution
for a maximum credit facility of $400.0 million, or 90% of the fair market value of the underlying collateral, to
establish a flexible draw down facility to fund additional stock repurchases, as necessary. This credit facility bore a
floating interest rate equal to the three-month USD LIBOR plus 40 basis points per annum and, if utilized, would be
secured by our publicly traded fixed income securities portfolio equivalent to 111% of any outstanding balance.
This credit facility was terminated on September 26, 2007. We did not utilize this credit facility at any time.

Net accounts receivable increased $130.3 million, or 52%, to $379.8 million from December 31, 2006 to
December 31, 2007 primarily due to an increase in revenue and shipment linearity. DSO was 42 days as of
December 31, 2007 as compared to 38 days as of December 31, 2006. The increase in DSO was primarily a result of
shipment linearity and the mix of customers we shipped to in the fourth quarter of 2007. Shipment linearity
represents the rate at which products are shipped during a period. Our distributor financing program had minimal
impact on DSO during 2007. Approximately $10.0 million of receivables sold under the distributor financing
program had not been recognized in net revenues as of December 31, 2007 and therefore such amounts were
recorded as debt financing in other accrued liabilities.

Deferred revenue increased $127.7 million or 33% to $513.3 million as of December 31, 2007 as compared to
December 31, 2006. Product and service deferred revenue increased $43.2 million and $84.5 million, respectively,
in 2007. Our product deferred revenue increased due to increases in the amount of product shipments not having met
revenue recognition criteria and service deferred revenue increased due to an increase in the installed base of
equipment under service contract.

55

Liquidity and capital resources may also be impacted by acquisitions and investments in strategic relationships
we may make in the networking equipment and information security markets. If we were to repurchase additional
shares of our common stock under our 2006 Stock Repurchase Program, our liquidity may be impacted.
Additionally, a portion of our cash and investment balance is held overseas and may be subject to U.S. taxes if
repatriated.

Based on past performance and current expectations, we believe that our existing cash and cash equivalents,
short-term and long-term investments, together with cash generated from operations as well as cash generated from
the exercise of employee stock options and purchases under our employee stock purchase plan will be sufficient to
fund our operations, repayment of outstanding debt, and growth. We believe our working capital is sufficient to
meet our liquidity requirements for capital expenditures, commitments, repurchases of our common stock, and
other liquidity requirements associated with our existing operations through at least the next 12 months.

However, our future capital requirements may vary materially from those now planned depending on many

factors, including:

• the overall levels of sales of our products and gross profit margins;

• our business, product, capital expenditure and research and development plans;

• the market acceptance of our products;

• repurchases of our common stock;

• issuance and repayment of debt;

• litigation expenses, settlements and judgments;

• volume price discounts and customer rebates;

• the levels of accounts receivable that we maintain;

• acquisitions of other businesses, assets, products or technologies;

• changes in our compensation policies;

• capital improvements for new and existing facilities;

• technological advances;

• our competitors’ responses to our products;

• our relationships with suppliers and customers;

• expenses related to our future restructuring plans, if any;

• tax expense associated with stock-based awards;

• issuance of stock-based awards and the related payment in cash for withholding taxes in the current year and

possibly during future years;

• the level of exercises of stock options and stock purchases under our equity incentive plans; and

• general economic conditions and specific conditions in our industry and markets, including the effects of

international conflicts and related uncertainties.

Cash Requirements and Contractual Obligations

Our principal commitments primarily consist of obligations outstanding under the Zero Coupon Convertible
Senior Notes due June 15, 2008 (“Senior Notes”), operating leases, purchase commitments, tax liabilities and other
contractual obligations. The following table summarizes our principal contractual obligations as of December 31,

(a) Our contractual obligations under operating leases primarily relate to our leased facilities under our non-
cancelable operating leases. Rent payments are allocated to costs and operating expenses in our consolidated
statements of operations. We occupy approximately 1.8 million square feet world wide under operating leases.
The majority of our office space is in North America, including our corporate headquarters in Sunnyvale,
California. Our longest lease expires in May 2016.

(b) Our principal commitment as of December 31, 2007 was our outstanding Senior Notes due June 15, 2008. The
Senior Notes were issued in June 2003 and are senior unsecured obligations, rank on parity in right of payment
with all of our existing and future senior unsecured debt, and rank senior to all of our existing and future debt
that expressly provides that it is subordinated to the notes. The Senior Notes bear no interest, but are convertible
into shares of our common stock, subject to certain conditions, at any time prior to maturity or their prior
repurchase by Juniper Networks. The conversion rate is 49.6512 shares per each $1,000 principal amount of
convertible notes, subject to adjustment in certain circumstances. This is equivalent to a conversion price of
approximately $20.14 per share. The carrying value of the Senior Notes as of December 31, 2007 was
$399.5 million, which was included in current liabilities as the debt is due in less than one year.

(c) In order to reduce manufacturing lead times and ensure adequate component supply, our contract manufacturers
place non-cancelable, non-returnable (“NCNR”) orders for components based on our build forecasts. As of
December 31, 2007, there were NCNR component orders placed by our contract manufacturers with a value of
$102.8 million. The contract manufacturers use the components to build products based on our forecasts and on
purchase orders we have received from our customers. Generally, we do not own the components and title to the
products transfers from the contract manufacturers to us and immediately to our customers upon delivery at a
designated shipment location. If the components go unused or the products go unsold for specified periods of
time, we may incur carrying charges or obsolete materials charges for components that our contract man-
ufacturers purchased to build products to meet our forecast or customer orders. As of December 31, 2007, we
had accrued $22.2 million based on our estimate of such charges.

(d) Tax liabilities include the long-term liabilities in the consolidated balance sheet for unrecognized tax positions.
At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years
beyond 12 months due to uncertainties in the timing of tax audit outcomes.

(e) Other contractual obligations consist of the escrow amount of $2.2 million and bonus accrual of $0.7 million in
connection with past acquisitions, a software subscription requiring payments of $5.0 million in both
January 2008 and January 2009 and a joint development agreement requiring quarterly payments of $3.5 million
through January 2010.

Summary of Cash Flows

Operating Activities

Net cash provided by operating activities was $786.5 million, $755.6 million, and $642.9 million for 2007,
2006 and 2005, respectively. The cash provided by operating activities for each period was due to our net income
(loss) adjusted by:

• Non-cash charges of $257.5 million, $1,536.4 million, and $307.4 million for 2007, 2006 and 2005,
respectively, primarily related to depreciation and amortization expenses, stock-based compensation, tax
benefit of employee stock option plans, in-process research and development from acquisitions, debt
issuance costs, restructuring expense, and impairment charges. Non-cash charges in 2007 and 2006 were
reduced by the excess tax benefit from stock-based compensation of $19.7 million and $9.7 million,
respectively, and a gain on a minority equity investment of $6.7 million.

Non-cash charges in 2006 also included charges of $1,283.4 million related to the impairment of goodwill
and intangible assets. In 2005 non-cash charges included $128.1 million of tax benefit from employee stock
options. Beginning in 2006, tax benefit from employee stock options, in accordance with FAS 123R, are no
longer included in cash flows from operations but rather are included in financing activities. Non-cash
charges in 2005 also included an in-process research and development charge, a benefit from the reversal of
NetScreen’s acquisition related liabilities and a loss due to the impairment of an equity investment, partially
offset by gains associated with available-for-sale investments.

• Net changes in operating assets and liabilities of $168.2 million, $220.6 million, and $(15.1) million for
2007, 2006 and 2005, respectively, were generally generated in the normal course of business. These
changes are highlighted as follows:

• Net cash increases in 2007 were primarily attributable to increases in accounts payable of $34.9 million,
an increase in accrued compensation of $48.3 million, an increase in taxes payable of $71.4 million and an
increase in deferred revenue of $127.7 million. The increase in accounts payable was due to the timing of
payments to contract manufacturers and the growth of our business. The increase in accrued compensation
was due to an increase in headcount, an increase in stock option exercises and the removal of the
suspension on employee purchases of shares under ESPP. The increase in taxes payable was due to the
increase in the tax provision, movement of deferred tax assets, and timing of payments. The increase in
deferred revenue was due to the growing installed base and customer payments in advance of product
acceptance. In addition, these increases in cash flows from operations were partially offset by a negative
cash flow of $120.9 million primarily due to an increase in net accounts receivable in 2007, which was
primarily due to the timing of shipments and the mix of customers who purchased our products, as we
shipped a larger amount of products late in the fourth quarter of 2007 and such invoices would not come
due until after December 31, 2007.

• Net cash increases in 2006 were primarily attributable to increases in deferred revenue of $132.8 million
due to the growing installed base and customer payments in advance of product acceptance. The increase
in operating cash flows was also due to the decreases in accounts receivable of $20.7 million and
aggregate decreases in prepaid expenses, other current assets and other long-term assets of $23.0 million.
Accounts payable increased $13.6 million and accrued compensation increased $12.7 million primarily
due to the costs of headcount increases and related employee bonuses. Changes in taxes payable and other
accrued liabilities contributed $18.3 million to cash flows from operations in 2006.

• Net cash used in 2005 from changes was primarily attributable to increases in net accounts receivable of
$68.1 million and decreases in other accrued liabilities of $100.7 million and accrued warranty of
$3.7 million, partially offset by decreases in the prepaid expenses, other current assets and other long-term
assets accounts of $5.3 million, increases in income taxes payable of $26.6 million, increases in deferred
revenue of $64.3 million, increases in accounts payable of $50.3 million and increases in accrued
compensation of $10.9 million.

Investing Activities

Net cash provided by investing activities was $571.8 million and $11.9 million for 2007 and 2006, respec-
tively. Net cash used in investing activities was $583.7 million for 2005. Investing activities primarily included the
purchases and sale or maturities of available-for-sale securities, the purchase and sale of equity investments, net
cash used in acquisitions and capital expenditures.

Net sales and maturities of investments in available-for-sale securities were $1,029.1 million in 2007,
compared to net sales and maturities of $632.1 million for 2006, as we used cash to fund our stock repurchase
program described under the financing activities section below. Purchases of available-for-sale securities used
$298.6 million in 2007 compared to $516.1 million in 2006 primarily due to the funding of our stock repurchase
program and our investment strategy during 2007. Positive net cash flows of $115.9 million generated from the
sales, maturities and purchases of available-for-sale securities in 2006 was primarily due to the increased cash and
cash equivalent holdings as a result of higher short-term interest rates. Purchases and sales or maturities of
available-for-sale securities used net cash of $131.0 million in 2005.

Capital expenditures increased $44.8 million to $146.9 million in 2007 and $3.9 million to $102.1 million in
2006 mainly to support new product developments and overseas expansions. Capital expenditures of $98.2 million
in 2005 mainly used in support of new product developments, overseas expansions and business acquisitions. Cash
flows related to restricted cash decreased by $27.9 million, from a cash inflow of $20.5 million in 2006 to a cash
outflow of $7.4 million in 2007, primarily due to the funding to the D&O insurance trust to increase coverage due to
the growth of our company. In 2005, we used cash of $309.9 million for the 2005 acquisitions, $34.8 million for
restricted cash funding to escrow accounts in relation to the 2005 acquisitions, and $9.8 million for minority equity
investment.

Financing Activities

Net cash used in financing activities was $1,238.5 million and $89.6 million for 2007 and 2006 respectively. In
2007 we repurchased 69.4 million shares of our common stock at an average price of $23.37 per share, or a total of
$1,623.2 million. In 2006, we repurchased 10.1 million shares of our common stock at an average price of
$18.51 per share, or a total of $186.4 million. In addition, cash was provided during both periods from the issuance
of common stock related to employee option exercises and stock purchase plans for a total of $355.0 million and
$87.1 million during 2007 and 2006, respectively. In 2007 and 2006, tax benefits of $19.7 million and $9.7 million,
respectively, from tax deductions in excess of the expense recognized for employee stock options was presented as
financing cash flows due to the adoption of FAS 123R, beginning on January 1, 2006. Tax deductions in excess of
the expense recognized for employee stock options were included in operating cash flows in 2005 before the
adoption of FAS 123R. Approximately $10.0 million of receivables sold under our distributor financing program
had not been recognized as revenue as of December 31, 2007 and therefore such amounts were recorded as net
borrowings under cash flows from financing activities.

Net cash provided by financing activities was $146.0 million in 2005 primarily due to common stock issued in

relation to employee option exercises and purchases under our Employee Stock Purchase Plan.

ITEM 7A. Quantitative and Qualitative Disclosure about Market Risk

Interest Rate Risk

We maintain an investment portfolio of various holdings, types and maturities. In addition, a portion of our
cash and marketable securities are held in non-U.S. domiciled countries. These securities are generally classified as
available-for-sale and, consequently, are recorded on our consolidated balance sheet at fair value with unrealized
gains or losses reported as a separate component of accumulated other comprehensive income (loss).

59

At any time, a rise in interest rates could have a material adverse impact on the fair value of our investment
portfolio. Conversely, declines in interest rates could have a material impact on interest earnings of our investment
portfolio. We do not currently hedge these interest rate exposures.

The following tables present hypothetical changes in fair value of the financial

instruments held at

December 31, 2007 and 2006 that are sensitive to changes in interest rates (in millions):

These instruments are not leveraged and are held for purposes other than trading. The modeling technique used
measures the changes in fair value arising from selected potential changes in interest rates. Market changes reflect
immediate hypothetical parallel shifts in the yield curve of plus or minus 50 basis points (BPS), 100 BPS and 150
BPS, which are representative of the historical movements in the Federal Funds Rate.

Foreign Currency Risk and Foreign Exchange Forward Contracts

Periodically, we use derivatives to hedge against fluctuations in foreign exchange rates. We do not enter into

derivatives for speculative or trading purposes.

We use foreign currency forward contracts to mitigate transaction gains and losses generated by certain foreign
currency denominated monetary assets and liabilities. These derivatives are carried at fair value with changes
recorded in other income (expense) in the same period as the changes in the fair value from the re-measurement of
the underlying assets and liabilities. These foreign exchange contracts have maturities between one and two months.

Our sales and costs of revenues are primarily denominated in U.S. dollars. Our operating expenses are
denominated in U.S. dollars as well as other foreign currencies including the British Pound, the Euro, Indian Rupee,
and Japanese Yen. Periodically, we use foreign currency forward and/or option contracts to hedge certain forecasted
foreign currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges
and have maturities of less than one year. The effective portion of the derivative’s gain or loss is initially reported as
a component of accumulated other comprehensive income and, upon occurrence of the forecasted transaction, is
subsequently reclassified into the consolidated statements of operations line item to which the hedged transaction
relates. We record any ineffectiveness of the hedging instruments, which was immaterial during the years ended
December 31, 2007, 2006 and 2005, respectively, in other income (expense) on our consolidated statements of
operations. The increase in operating expenses including research and development, sales and marketing, as well as
general and administrative expenses, due to foreign currency fluctuations, net of hedging, was approximately 2% in
2007.

60

Equity Price Risk

Our portfolio of publicly-traded equity securities is inherently exposed to equity price risk as the stock market
fluctuates. We monitor our equity investments for impairment on a periodic basis. In the event that the carrying
value of the equity investments exceeds its fair value, and we determine the decline in value to be other than
temporary, we reduce the carrying value to its current fair value. We do not purchase our equity securities with the
intent to use them for trading or speculative purposes. The aggregate fair value of our marketable equity securities
was $8.6 million and $0.8 million as of December 31, 2007 and 2006, respectively. A hypothetical 30% adverse
change in the stock prices of our portfolio of publicly-traded equity securities would result in an immaterial loss.

In addition to publicly-traded securities, we have also invested in privately-held companies. These investments
are carried at cost. The aggregate cost of our investments in privately-held companies was $23.3 million and
$20.4 million as of December 31, 2007 and 2006, respectively.

ITEM 8. Consolidated Financial Statements and Supplementary Data

Management’s Annual Report on Internal Control Over Financial Reporting

Juniper Networks Inc.’s management is responsible for establishing and maintaining adequate internal control
over the company’s financial reporting. We assessed the effectiveness of the company’s internal control over
financial reporting as of December 31, 2007. In making this assessment, we used the criteria set forth by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated
Framework.

Based on our assessment using those criteria, we concluded that, as of December 31, 2007, Juniper Networks

Inc.’s internal control over financial reporting was effective.

Our independent registered public accounting firm, Ernst & Young LLP, independently assessed the effec-
tiveness of the company’s internal control over financial reporting. Ernst & Young has issued an attestation report
concurring with management’s assessment, which is included on page 65 of this Form 10-K.

Please note that there are inherent limitations in the effectiveness of any system of internal control, including
the possibility of human error and the circumvention or overriding of controls. Accordingly, even effective internal
controls can provide only reasonable assurances with respect to financial statement preparation. Further, because of
changes in conditions, the effectiveness of internal control may vary over time.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Juniper Networks, Inc.

We have audited the accompanying consolidated balance sheets of Juniper Networks, Inc. as of December 31,
2007 and 2006, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each
of the three years in the period ended December 31, 2007. Our audits also included the financial statement schedule
listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s
management. Our responsibility is to express an opinion on these financial statements and schedule based on our
audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of Juniper Networks, Inc. at December 31, 2007 and 2006, and the consolidated
results of its operations and its cash flows for each of the three years in the period ended December 31, 2007, in
conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement
schedule, when considered in relation to the basic financial statements taken as a whole, present fairly in all material
respects, the information set forth therein.

As discussed in Note 1 to the Consolidated Financial Statements, Juniper Networks, Inc. changed its method of
accounting for stock-based compensation as of January 1, 2006, and its method of accounting for uncertain tax
positions as of January 1, 2007.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the effectiveness of Juniper Networks, Inc.’s internal control over financial reporting as of
December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2008
expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Juniper Networks, Inc.

We have audited Juniper Network, Inc.’s internal control over financial reporting as of December 31, 2007,
based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (the COSO criteria). Juniper Networks, Inc.’s management is
responsible for maintaining effective internal control over financial reporting, and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Management’s Annual
Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s
internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

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

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

In our opinion, Juniper Networks, Inc. maintained, in all material respects, effective internal control over

financial reporting as of December 31, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the accompanying consolidated balance sheets as of December 31, 2007 and 2006, and the related
consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period
ended December 31, 2007 of Juniper Networks, Inc. and our report dated February 28, 2008 expressed an
unqualified opinion thereon.

Notes to Consolidated Financial Statements

Note 1. Description of Business

Juniper Networks, Inc. (“Juniper Networks” or the “Company”) designs, develops and sells products and
services that together provide its customers with high-performance network infrastructure that creates responsive
and trusted environments for accelerating the deployment of services and applications over a single Internet
Protocol (“IP”)-based network. The Company organizes its business groups into the following three reportable
segments: Infrastructure, Service Layer Technologies (“SLT”), and Service. The Company’s Infrastructure segment
primarily offers scalable router products that are used to control and direct network traffic. The Company’s SLT
segment offers networking solutions that meet a broad array of its customers’ priorities, from securing the network
and the data on the network, to maximizing existing bandwidth and acceleration of applications across a distributed
network. Together, these elements provide secure networking solutions to enable customers to convert legacy
networks that provide commoditized, best efforts services into more valuable assets that provide differentiation,
value and increased reliability, performance and security to end users. The Company’s Service segment delivers
world-wide services, including technical support and professional services, as well as a number of education and
training programs, to customers of the Infrastructure and SLT segments.

Basis of Presentation

The Consolidated Financial Statements include the Company and its wholly-owned subsidiaries. All inter-

company balances and transactions have been eliminated.

Use of Estimates

The preparation of the financial statements and related disclosures in conformity with accounting principles
generally accepted in the United States requires management to make estimates and judgments that affect the
amounts reported in the Consolidated Financial Statements and accompanying notes. Estimates are used for
revenue recognition, allowance for sales returns, allowance for doubtful accounts, allowance for contract man-
ufacturer obligations, allowance for warranty costs, stock-based compensation, goodwill and other impairments,
income taxes, litigation and settlement costs, and other loss contingencies. The Company bases its estimates on
historical experience and also on assumptions that it believes are reasonable. Actual results experienced by the
Company may differ materially from management’s estimates.

Cash and Cash Equivalents

All highly liquid investments purchased with an original maturity of three months or less are classified as cash
and cash equivalents. Cash and cash equivalents consist of cash on hand, balances with banks, and highly liquid
investments in money market funds, commercial paper, government securities, certificates of deposit, and corporate
debt securities.

Investments

Management determines the appropriate classification of securities at the time of purchase and reevaluates
such classification as of each balance sheet date. Realized gains and losses and declines in value judged to be other
than temporary are determined based on the specific identification method and are reported in the Consolidated
Statements of Operations. The Company’s investments in publicly traded equity securities are classified as
available-for-sale. Available-for-sale investments are initially recorded at cost and periodically adjusted to fair
value through comprehensive income (loss).

Equity Investments

Juniper Networks has investments in privately held companies. These investments are included in other long-
term assets in the Consolidated Balance Sheets and are carried at cost, adjusted for any impairment, as the Company

70

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

does not have a controlling interest and does not have the ability to exercise significant influence over these
companies. These investments are inherently high risk as the market for technologies or products manufactured by
these companies are usually early stage at the time of the investment by Juniper Networks and such markets may
never be significant. The Company monitors these investments for impairment by considering financial, operational
and economic data and makes appropriate reductions in carrying values when necessary.

Fair Value of Financial Instruments

The carrying value of the Company’s financial instruments including cash and cash equivalents, accounts
receivable, accrued compensation, and other accrued liabilities, approximates fair market value due to the relatively
short period of time to maturity. The fair value of investments is determined using quoted market prices for those
securities or similar financial instruments.

Concentrations

Financial instruments that subject Juniper Networks to concentrations of credit risk consist primarily of cash
and cash equivalents, investments and accounts receivable. Juniper Networks maintains its cash and cash equiv-
alents and investments in fixed income securities with high-quality institutions and only invests in high quality
credit instruments. Deposits held with banks, including those held in foreign branches of global banks, may exceed
the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and
therefore bear minimal risk.

Generally, credit risk with respect to accounts receivable is diversified due to the number of entities comprising
the Company’s customer base and their dispersion across different geographic locations throughout the world.
Juniper Networks performs ongoing credit evaluations of its customers and generally does not require collateral on
accounts receivable. Juniper Networks maintains reserves for potential credit losses and historically such losses
have been within management’s expectations. One customer accounted for 12.8%, 14.3% and 13.7% of total net
revenues during 2007, 2006 and 2005, respectively.

The Company relies on sole suppliers for certain of its components such as application-specific integrated
circuits (“ASICs”) and custom sheet metal. Additionally, Juniper Networks relies primarily on a limited number of
significant independent contract manufacturers for the production of all of its products. The inability of any supplier
or manufacturer to fulfill supply requirements of Juniper Networks could negatively impact future operating results.

Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation. Depreciation is calculated using
the straight-line method over the lesser of the estimated useful life, generally three to five years, or the lease term of
the respective assets. The Company depreciates leasehold improvements over the life of the lease or the respective
assets, whichever is shorter. Land is not subject to depreciation.

Goodwill and Purchased Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable
intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities
accounted for using the purchase method of accounting are estimated by management based on the fair value of
assets received. Identifiable intangible assets are comprised of purchased trademarks, developed technologies,
customer and maintenance contracts, and other intangible assets. Goodwill is not subject to amortization but is
subject to annual assessment, at a minimum, for impairment by applying a fair-value based test. Future goodwill
impairment tests could result in a charge to earnings. Purchased intangible assets with finite lives are amortized on a
straight-line basis over their respective estimated useful lives ranging from two to nineteen years.

Impairment

The Company evaluates long-lived assets held-for-use for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable. An asset is considered
impaired if its carrying amount exceeds the future net cash flow the asset is expected to generate. If an asset is
considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying
amount of the asset exceeds its fair market value. The Company assesses the recoverability of its long-lived and
intangible assets by determining whether the unamortized balances can be recovered through undiscounted future
net cash flows of the related assets. The amount of impairment, if any, is measured based on projected discounted
future net cash flows.

The Company evaluates goodwill, at a minimum, on an annual basis and whenever events and changes in
circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment of goodwill is
tested at the reporting unit level by comparing the reporting unit’s carrying value, including goodwill, to the fair
value of the reporting unit. The fair values of the reporting units are estimated using a combination of the income, or
discounted cash flows, approach and the market approach, which utilizes comparable companies’ data. If the
carrying value of the reporting unit exceeds the fair value, goodwill is considered impaired and a second step is
performed to measure the amount of the impairment loss, if any. As discussed in Note 3, in the second quarter of
2006 the Company concluded that the carrying value of goodwill was impaired and recorded an impairment charge.
After recording the impairment charge, Juniper Networks conducted its annual impairment test as of November 1,
2006 and November 1, 2007 and determined that the carrying value of the remaining goodwill was not impaired.
There were no events or circumstances from November 1, 2007 through December 31, 2007 that would impact this
assessment. Future impairment indicators, including declines in the Company’s market capitalization or a decrease
in revenue or profitability levels, could require additional impairment charges to be recorded.

Revenue Recognition

Juniper Networks sells products and services through its direct sales force and through its strategic distribution
relationships and value-added resellers. The Company’s products are integrated with software that is essential to the
functionality of the equipment. Additionally, the Company provides unspecified upgrades and enhancements
related to the integrated software through maintenance contracts for most of its products. Accordingly, the
Company accounts for revenue in accordance with Statement of Position No. 97-2, Software Revenue Recognition,
and all related interpretations. The Company recognizes revenue when persuasive evidence of an arrangement
exists, delivery or performance has occurred, the sales price is fixed or determinable and collectibility is reasonably
assured. Evidence of an arrangement generally consists of customer purchase orders and, in certain instances, sales
contracts or agreements. Shipping terms and related documents, or written evidence of customer acceptance, when
applicable, are used to verify delivery or performance. In instances where the Company has outstanding obligations
related to product delivery or the final acceptance of the product, revenue is deferred until all the delivery and
acceptance criteria have been met. The Company assesses whether the sales price is fixed or determinable based on
payment terms and whether the sales price is subject to refund or adjustment. Collectibility is assessed based on the
creditworthiness of the customer as determined by credit checks and the customer’s payment history to the
Company. Accounts receivable are recorded net of allowance for doubtful accounts, estimated customer returns and
pricing credits.

For arrangements with multiple elements, such as sales of products that include services, the Company
allocates revenue to each element using the residual method based on vendor specific objective evidence of fair
value of the undelivered items. Under the residual method, the amount of revenue allocated to delivered elements
equals the total arrangement consideration less the aggregate fair value of any undelivered elements. Vendor
specific objective evidence of fair value is based on the price charged when the element is sold separately. If vendor
specific objective evidence of fair value of one or more undelivered items does not exist, revenue is deferred and
recognized at the earlier of (i) delivery of those elements or (ii) when fair value can be established unless

72

Notes to Consolidated Financial Statements — (Continued)

maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over
the contractual support period. For multiple agreements with a single customer, the Company accounts for them as
either one arrangement or separate arrangements depending on their interdependency.

For sales to direct end-users and value-added resellers, the Company recognizes product revenue upon transfer
of title and risk of loss, which is generally upon shipment. It is the Company’s practice to identify an end-user prior
to shipment to a value-added reseller. For end-users and value-added resellers, the Company has no significant
obligations for future performance such as rights of return or pricing credits. A portion of the Company’s sales are
made through distributors under agreements allowing for pricing credits and/or rights of return. Product revenue on
sales made through these distributors is recognized upon sell-through as reported by the distributors to the
Company. The Company sells certain interests in accounts receivables on a non-recourse basis as part of a
distributor accounts receivable financing arrangement which was established by the Company with a major
financing company. Accounts receivables sold under this arrangement in advance of revenue recognition are
accounted for as debt and had a balance of $10.0 million and nil as of December 31, 2007 and 2006, respectively.
Deferred revenue on shipments to distributors reflects the effects of distributor pricing credits and the amount of
gross margin expected to be realized upon sell — through. Deferred revenue is recorded net of the related product
costs of revenue.

The Company records reductions to revenue for estimated product returns and pricing adjustments, such as
rebates and price protection, in the same period that the related revenue is recorded. The amount of these reductions
is based on historical sales returns and price protection credits, specific criteria included in rebate agreements, and
other factors known at the time. In addition, the Company reports revenue net of sales taxes.

Shipping charges billed to customers are included in product revenue and the related shipping costs are
included in cost of product revenues. Costs associated with cooperative advertising programs are estimated and
recorded as a reduction of revenue at the time the related sales are recognized.

Services include maintenance, training and professional services. In addition to providing unspecified
upgrades and enhancements on a when and if available basis, the Company’s maintenance contracts include
24-hour technical support, and hardware repair and replacement parts. Maintenance is offered under renewable
contracts. Revenue from maintenance contracts is deferred and is generally recognized ratably over the contractual
support period, which is generally one to three years. Revenue from training and professional services is recognized
as the services are completed or ratably over the contractual period, which is generally one year or less.

Allowance for Doubtful Accounts

The allowance for doubtful accounts is based on the Company’s assessment of the collectibility of customer
accounts. Juniper Networks regularly reviews its receivables that remain outstanding past their applicable payment
terms and establishes allowance and potential write-offs by considering factors such as historical experience, credit
quality, age of the accounts receivable balances and current economic conditions that may affect a customer’s
ability to pay.

Warranties

Juniper Networks generally offers a one-year warranty on all of its hardware products and a 90-day warranty
on the media that contains the software embedded in the products. The warranty generally includes parts and labor
obtained through the Company’s 24-hour service center. On occasion, the specific terms and conditions of those
warranties vary. The Company accrues for warranty costs based on estimates of the costs that may be incurred under
its warranty obligations, including material costs, technical support labor costs and associated overhead. The
warranty accrual is included in the Company’s cost of revenues and is recorded at the time revenue is recognized.
Factors that affect the Company’s warranty liability include the number of installed units, its estimates of
anticipated rates of warranty claims, costs per claim and estimated support labor costs and the associated overhead.

73

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as
necessary.

Contract Manufacturer Liabilities and Inventories

The Company outsources most of its manufacturing, repair and supply chain management operations to its
independent contract manufacturers and a significant portion of its cost of revenues consists of payments to them.
Its independent contract manufacturers procure components and manufacture the Company’s products based on the
Company’s demand forecasts. These forecasts are based on the Company’s estimates of future demand for the
Company products, which are in turn based on historical trends and an analysis from the Company’s sales and
marketing organizations, adjusted for overall market conditions. The Company establishes accrued liabilities,
included in other current accrued liabilities on the accompanying consolidated balance sheets, for carrying charges
and obsolete material charges for excess components purchased based on historical trends.

In addition, the Company purchases a small amount of strategic component inventory, which is included in
other assets, and stated at the lower of cost or market. The costs of distributor inventory not yet recognized as
revenue is recorded net of the related product revenue. Service related spares and demonstration equipment are
expensed to costs of service revenue and sales and marketing expense, respectively, when purchased.

Research and Development

Costs to research, design, and develop the Company’s products are expensed as incurred. Software devel-
opment costs are capitalized beginning when a product’s technological feasibility has been established and ending
when a product is available for general release to customers. Generally, Juniper Networks’ products are released
soon after technological feasibility has been established. As a result, costs subsequent to achieving technological
feasibility have not been significant and all software development costs have been expensed as incurred.

Advertising

Advertising costs are charged to sales and marketing expense as incurred. Advertising expense was $4.8 mil-

lion, $6.8 million, and $6.6 million, for 2007, 2006 and 2005, respectively.

Loss Contingencies

The Company is subject to the possibility of various loss contingencies arising in the ordinary course of
business. It considers the likelihood of loss or impairment of an asset or the incurrence of a liability, as well as its
ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency
is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss
can be reasonably estimated. The Company regularly evaluates current information available to its management to
determine whether such accruals should be adjusted and whether new accruals are required.

In addition, from time to time, the Company is involved in disputes, litigation and other legal actions. The
Company records a charge equal to at least the minimum estimated liability for a loss contingency only when both
of the following conditions are met: (i) information available prior to issuance of the financial statements indicates
that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial
statements and (ii) the range of loss can be reasonably estimated. However the actual liability in any such litigation
may be materially different from the Company’s estimates, which could result in the need to record additional
expenses.

Stock-Based Compensation

On January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123 (revised 2004),
Share-Based Payment, (“FAS 123R”) which requires the measurement and recognition of compensation expense for all

74

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

stock-based awards made to employees and directors including employee stock options, restricted stock units (“RSUs”)
and purchases under the Company’s Employee Stock Purchase Plan based on estimated fair values. FAS 123R
supersedes the previous accounting under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees (“APB 25”), as allowed under Statement of Financial Accounting Standards No. 123, Accounting for Stock-
Based Compensation (“FAS 123”), for periods beginning in 2006. In March 2005, the Securities and Exchange
Commission (“SEC”) issued Staff Accounting Bulletin No. 107 (“SAB 107”) relating to FAS 123R. The Company has
applied the provisions of SAB 107 in conjunction with its adoption of FAS 123R.

The Company adopted FAS 123R using the modified prospective transition method, which requires the
application of the accounting standard as of January 1, 2006, the first day of the Company’s fiscal 2006. FAS 123R
requires companies to estimate the fair value of stock-based awards on the date of grant using an option-pricing model.
The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of stock options under
FAS 123R, consistent with that used for pro forma disclosures under FAS 123. The fair value of an RSU is equivalent
to the market price of the Company’s common stock on the grant date. The value of the portion of the stock-based
award that is ultimately expected to vest is recognized as expense over the requisite service periods, or in the period of
grant if the requisite service period has been provided, in the Company’s Consolidated Statement of Operations.

The Company’s Consolidated Financial Statements as of and for the years ended December 31, 2007 and 2006
reflect the impact of FAS 123R. In accordance with the modified prospective transition method, the Company’s
consolidated financial statements for 2005 have not been restated to reflect, and do not include, the impact of FAS 123R.

Stock-based compensation expense recognized in the Company’s consolidated statement of operations for the
years ended December 31, 2007 and 2006 included (i) compensation expense for stock-based awards granted prior
to, but not yet vested as of, December 31, 2005 based on the grant date fair value estimated in accordance with the
provisions of FAS 123 and (ii) compensation expense for the stock-based awards granted subsequent to
December 31, 2005 based on the grant date fair value estimated in accordance with the provisions of FAS 123R.
In conjunction with the adoption of FAS 123R, the Company changed its accounting policy of attributing the fair
value of stock-based compensation to expense from the accelerated multiple-option approach provided by APB 25,
as allowed under FAS 123, to the straight-line single-option approach, as allowed under FAS 123R. Compensation
expense for all expected-to-vest stock-based awards that were granted on or prior to December 31, 2005 will
continue to be recognized using the accelerated attribution method. Compensation expense for all expected-to-vest
stock-based awards that were granted or modified subsequent to December 31, 2005 is recognized on a straight-line
basis provided that the amount of compensation cost recognized at any date is no less than the portion of the grant-
date value of the award that is vested at that date. FAS 123R requires forfeitures to be estimated at the time of grant
and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. In the Company’s
stock-based compensation expense required under APB 25 and the pro forma information required under FAS 123
for 2005, the Company accounted for forfeitures as they occurred.

Prior to the adoption of FAS 123R, stock-based compensation expense was recognized in the Company’s
consolidated statement of operations under the provisions of APB 25. In accordance with APB 25, no compensation
expense was required for the employee stock purchases under the Company’s Employee Stock Purchase Plan.
Stock-based compensation expense of $22.3 million for 2005 was related to employee stock-based awards and
stock options assumed from acquisitions. As a result of adopting FAS 123R, stock-based compensation expense
recorded for 2007 and 2006 was $88.0 million and $87.6 million, respectively. Stock-based compensation under
FAS 123R for 2006, the year of adoption, was approximately $74.4 million higher than that which would have been
reported had the Company continued to account for stock-based compensation under APB 25. Net income for 2006
was approximately $51.4 million lower than that which would have been reported had the Company continued to
account for stock-based compensation under APB 25. Unamortized deferred compensation associated with stock
options assumed from past acquisitions and employee stock-based awards of $17.7 million has been reclassified to
additional paid-in capital in the Company’s consolidated balance sheet upon the adoption of FAS 123R on January 1,
2006. Additional information is discussed in Note 9, “Stockholders’ Equity.”

75

Notes to Consolidated Financial Statements — (Continued)

In accordance with FAS 123R, the Company has presented as financing cash flows the tax benefits resulting from
tax deductions in excess of the compensation cost recognized for those options beginning in 2006. Tax benefits from
employee stock plans of $19.7 million and $9.7 million, which related to tax deductions in excess of the compensation
cost recognized, were presented as financing cash flows for 2007 and 2006, respectively. Prior to the adoption of
FAS 123R, tax benefits from employee stock plans were presented as operating cash flows. Additionally, in
accordance with FAS 123R, FAS No. 109, Accounting for Income Taxes (“FAS 109”), and EITF Topic D-32,
Intra-period Tax Allocation of the Effect of Pretax Income from Continuing Operations, the Company has elected to
recognize excess income tax benefits from stock option exercises in additional paid-in capital only if an incremental
income tax benefit would be realized after considering all other tax attributes presently available to the Company.

The following table summarizes the pro forma net income and earnings per share, net of related tax effect, had

Derivatives

Periodically, the Company uses derivatives to partially offset its market exposure to fluctuations in foreign
currencies. The Company does not enter into derivatives for speculative or trading purposes. Juniper Networks uses
foreign currency forward contracts to mitigate transaction gains and losses generated by certain foreign currency
denominated monetary assets and liabilities. These derivatives are carried at fair value with changes recorded in
other income (expense) in the same period as changes in the fair value from re-measurement of the underlying assets
and liabilities. Cash flows from such hedges are classified as operating activities. These foreign exchange forward
contracts have maturities between one and two months.

The Company also uses foreign currency forward and/or option contracts to hedge certain forecasted foreign
currency transactions relating to operating expenses. These derivatives are designated as cash flow hedges and have
maturities of less than one year. The effective portion of the derivative’s gain or loss is initially reported as a
component of accumulated other comprehensive income, and upon occurrence of the forecasted transaction, is
subsequently reclassified into the consolidated statements of operations line item to which the hedged transaction
relates. The Company records any ineffectiveness of the hedging instruments, which was immaterial during 2007,
2006 and 2005 in other income (expense) on its Consolidated Statements of Operations. Cash flows from such
hedges are classified as operating activities.

Provision for Income Taxes

Estimates and judgments occur in the calculation of certain tax liabilities and in the determination of the
recoverability of certain deferred tax assets, which arise from temporary differences and carryforwards. Deferred
tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for
the years in which those tax assets are expected to be realized or settled. The Company regularly assesses the
likelihood that its deferred tax assets will be realized from recoverable income taxes or recovered from future
taxable income based on the realization criteria set forth under FAS 109, Accounting for Income Taxes, and records a
valuation allowance to reduce its deferred tax assets to the amount that it believes to be more likely than not
realizable. The Company believes it is more likely than not that forecasted income together with the tax effects of
the deferred tax liabilities, will be sufficient to fully recover the remaining deferred tax assets. In the event that all or
part of the net deferred tax assets are determined not to be realizable in the future, an adjustment to the valuation
allowance would be charged to earnings in the period such determination is made. Similarly, if the Company
subsequently realizes deferred tax assets that were previously determined to be unrealizable, the respective
valuation allowance would be reversed, resulting in a positive adjustment to earnings or a decrease in goodwill in
the period such determination is made. In addition, the calculation of tax liabilities involves dealing with
uncertainties in the application of complex tax regulations. The Company recognizes potential liabilities based
on its estimate of whether, and the extent to which, additional taxes will be due.

On January 1, 2007, the Company adopted the Financial Accounting Standards Board (“FASB”) Interpretation
No. 48, Accounting for Uncertainty in Income Taxes, (“FIN 48”). FIN 48 is an interpretation of FASB Statement
109, Accounting for Income Taxes, and it seeks to reduce the diversity in practice associated with certain aspects of
measurement and recognition in accounting for income taxes. FIN 48 prescribes a recognition threshold and
measurement attribute for the financial statement recognition and measurement of a tax position that an entity takes
or expects to take in a tax return. Additionally, FIN 48 provides guidance on de-recognition, classification, interest
and penalties, accounting in interim periods, disclosures and transition. Under FIN 48, an entity may only recognize
or continue to recognize tax positions that meet a “more likely than not” threshold. In addition, the application of
FIN 48 may increase an entity’s future effective tax rates and its future intra-period effective tax rate volatility. The
Company’s cumulative effect of applying FIN 48 was a $19.2 million increase to the opening balance of
accumulated deficit as of January 1, 2007 and a $1.0 million increase to goodwill.

Comprehensive Income

Comprehensive income is defined as the change in equity during a period from non-owner sources. The
Company has presented its comprehensive income as part of the Consolidated Statements of Stockholders’ Equity.
Other comprehensive income includes net unrealized gains (losses) on available-for-sale securities and net foreign
currency translation gains (losses) that are excluded from net income, and unrealized gains (losses) on derivatives
designated as cash flow hedges.

Foreign Currency Translation

Assets and liabilities of foreign operations with non-U.S. dollar functional currency are translated to
U.S. dollars using exchange rates in effect at the end of the period. Revenue and expenses are translated to
U.S. dollars using average exchange rates for the period. Foreign currency translation gains and losses were not
material for the years ended December 31, 2007, 2006 and 2005. The effect of exchange rate changes on cash
balances held in foreign currencies was immaterial in the years presented.

Recent Accounting Pronouncements

In December 2007, the FASB issued FAS No. 160, Noncontrolling Interests in Consolidated Financial
Statements — an amendment of Accounting Research Bulletin No. 51 (“FAS 160”). FAS 160 addresses the
accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent,

77

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a
parent’s ownership interest, and the valuation of retained noncontrolling equity investments when a subsidiary is
deconsolidated. FAS 160 also establishes disclosure requirements that clearly identify and distinguish between the
interests of the parent and the interests of the noncontrolling owners. FAS 160 is effective for fiscal years beginning
after December 15, 2008, and will be adopted by the Company in 2009. The Company is currently assessing the
impact of this standard on its future consolidated results of operations and financial condition.

In December 2007, the FASB issued FAS No. 141R, Business Combinations (“FAS 141R”). FAS 141R
establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial
statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree.
The statement also provides guidance for recognizing and measuring the goodwill acquired in the business
combination and determines what information to disclose to enable users of the financial statement to evaluate the
nature and financial effects of the business combination. FAS 141R is effective for financial statements issued for
fiscal years beginning after December 15, 2008. Accordingly, any business combinations the Company engages in
will be recorded and disclosed following existing GAAP until January 1, 2009. The Company expects FAS No. 141R
will have an impact on its consolidated financial statements when effective, but the nature and magnitude of the
specific effects will depend upon the nature, terms and size of the acquisitions it consummates after the effective
date. The Company is currently assessing the impact of this standard on its future consolidated results of operations
and financial condition.

In June 2007, the FASB ratified EITF 07-3, Accounting for Non-Refundable Advance Payments for Goods or
Services Received for Use in Future Research and Development Activities (“EITF 07-3”). EITF 07-3 requires that
nonrefundable advance payments for goods or services that will be used or rendered for future research and
development activities be deferred, capitalized and recognized as an expense as the goods are delivered or the
related services are performed. EITF 07-3 is effective, on a prospective basis, for fiscal years beginning after
December 15, 2007. The Company adopted EITF 07-3 on January 1, 2008 and does not expect any material impact
on its consolidated results of operations and financial condition.

In February 2007, the FASB issued FAS No. 159, The Fair Value Option for Financial Assets and Financial
Liabilities-including an amendment of FASB Statement No. 115 (“FAS 159”). FAS 159 expands the use of fair value
accounting but does not affect existing standards which require assets or liabilities to be carried at fair value. The
objective of FAS 159 is to improve financial reporting by providing companies with the opportunity to mitigate
volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply
complex hedge accounting provisions. Under FAS 159, an entity may elect to use fair value to measure eligible
items including accounts receivable, available-for-sale and held-to-maturity securities, equity method investments,
accounts payable, guarantees, and issued debt. The adoption of FAS No. 159 is not expected to have a significant
impact on the Company’s consolidated financial statements.

In September 2006, the FASB issued FAS No. 157, Fair Value Measurements (“FAS 157”). FAS 157 defines
fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and
expands disclosures about fair value measurements. Under this guidance, fair value measurements would be
separately disclosed by level within the fair value hierarchy. FAS 157 is effective for financial statements issued for
fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. In February 2008, the
FASB issued FASB Staff Position No. FAS 157-2, Effective Date of FASB Statement No. 157, (“FSP FAS 157-2”).
FSP FAS 157-2 amends FAS 157 to delay the effective date of FAS 157 for non-financial assets and non-financial
liabilities until fiscal years beginning after November 15, 2008, except for items that are recognized or disclosed at
fair value in the financial statements on a recurring basis. The Company adopted the effective portion of FAS 157 on
January 1, 2008 and does not expect any material impact on its consolidated results of operations and financial
condition. The Company is currently assessing the impact of applying FAS 157 to its non-financial assets and
liabilities on its future consolidated results of operations and financial condition.

The total initial purchase price for certain acquisitions could increase upon the release of the amounts held in

escrow for indemnity obligations and upon additional contingent payments.

Allocation of Initial Purchase Consideration

The Company allocated the purchase price to the tangible and intangible assets acquired and liabilities
assumed, including IPR&D, based on their fair values. The excess purchase price over those fair values is recorded
as goodwill. Goodwill is subject to change due to the release of the amounts held in escrow for indemnity
obligations, additional contingent payments, and changes in acquisition related assets and liabilities. The fair values
assigned to intangible assets acquired were based on valuations prepared by independent third-party appraisal firms

Existing technology consists of products that have reached technological feasibility and includes products in
the acquired product lines. Existing technology was valued using the discounted cash flow (“DCF”) method. This
method calculates the value of the intangible asset as being the present value of the after tax cash flows potentially
attributable to it, net of the return on fair value attributable to tangible and other intangible assets.

Patents and core technology represent a combination of processes, patents, and trade secrets that were used for
existing and in-process technology. The value of the trade name and trademarks is represented by the benefit of
owning these intangible assets rather than paying royalties for their use. Both of these intangible assets were valued
using the royalty savings method. This method estimates the value of these intangible assets by capitalizing the
royalties saved because the Company owns the assets.

Relationships with customers represent the rights granted to the VAR or distributor to resell certain products.
The VAR and distributor relationships were valued using the avoided cost method, which takes into account the cost
of establishing each relationship.

Maintenance agreements represent the revenue generated by contracts with customers who pay for annual
maintenance and support. The income approach was used to estimate the fair value of the maintenance agreements,
which includes estimating the ongoing, after-tax income expected from maintenance agreements in place at the
time of each acquisition, including expected renewals.

Pro forma results of operations are not presented for the 2005 acquisitions as the effects of these acquisitions

are not material to Juniper Networks on either an individual or an aggregate annual basis.

Funk Acquisition: On December 1, 2005, the Company completed its acquisition of Funk. Funk was a leading
provider of standards-based network access security solutions, developed products and technologies that protect the
integrity of the network by ensuring both the user and the device meet an organization’s security policies before granting
access. The purchase price for Funk included a cash payment of $110.2 million. Excluded from the initial purchase price
of $111.3 million was a balance of $12.2 million held in escrow for indemnity obligations, of which one-half expired in
January 2007 and the remaining one-half in June 2007. The Company paid $4.8 million and $6.6 million in January 2007
and July 2007, respectively, upon resolution of certain acquisition related indemnity issues, and increased goodwill for
the corresponding amounts. Contingent payments associated with future employment conditions were recorded as
compensation expense ratably over the 13 month period from the acquisition date. As of December 31, 2007, the
Company had retained $1.6 million in escrow to satisfy potential indemnity obligations.

Acorn Acquisition: On October 20, 2005, the Company completed its acquisition of Acorn. Acorn’s products and
technologies provide a smooth migration path by connecting legacy Time Division Multiplexing (“TDM”) and other
circuit-based applications across next-generation IP networks. The purchase price for Acorn included a cash payment of
$4.0 million. Excluded from the initial purchase price of $4.3 million was a balance of $2.5 million held in escrow for
indemnity and earn-out obligations, which expired on May 30, 2007. The Company paid $1.6 million in May 2007, upon
resolution of certain acquisition related indemnity issues, and increased goodwill by the corresponding amount.
Contingent payments associated with future employment conditions were recorded as compensation expense ratably
over the 12 month period following the acquisition.

Peribit Acquisition: On July 1, 2005, the Company completed its acquisition of Peribit. The acquisition
enabled the Company to secure and assure the delivery and performance of applications over an IP network through
premium traffic processing. The purchase price for Peribit included a cash payment of $50.3 million. The
acquisition resulted in the issuance of 11.3 million shares of the Company’s common stock with a fair value of
approximately $256.4 million to the former shareholders of Peribit, of which, approximately 1.6 million shares with
a fair value of $35.2 million, established as of the acquisition date, were being held in escrow for indemnity
obligations prescribed by the merger agreement. The common stock issued in the acquisition was valued using the
average closing price of the Company’s common stock over a five-day trading period beginning two days before and
ending two days after the date the transaction was announced on April 26, 2005. The Company also assumed all of
the outstanding Peribit stock options with a fair value of approximately $36.4 million. Such options were valued
using Black-Scholes option pricing model with the volatility assumption of 41%, expected life of 1.8 years, risk-
free interest rate of 3.6%, and a market value of the Company’s common stock of $22.62 per share, which was
determined as described above. At the close of the acquisition, the Company recorded a liability of $3.0 million
associated with future lease, severance, and other contractual obligations through March 2009. In July of 2006, the
Company released 0.8 million shares valued at $10.3 million to the former shareholders of Peribit which were
formerly held in escrow. The remaining shares in escrow expired on February 1, 2007. A total of 0.8 million escrow
shares were distributed in February 2007 and July 2007 at the then current market value of $19.15 per share and
$27.22 per share, respectively, with an aggregate fair value of $14.8 million. The escrow amounts were excluded
from the initial purchase price of $312.0 million.

Redline Acquisition: On May 2, 2005, the Company completed its acquisition of Redline. Redline was a
pioneer in the development of Application Front End (“AFE”) technology and designed network solutions that
improve the performance, flexibility, and scalability of web-enabled enterprise data centers and public web sites.
The initial purchase price for Redline included a cash payment of $97.5 million, a $3.0 million pre-acquisition loan
from the Company to Redline which was forgiven, and assumed stock options with an aggregate fair value of

81

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

$21.1 million. The stock options were valued using the Black-Scholes option pricing model with the inputs of 43%
for volatility, 1.56 years for expected life, 3.5% for risk-free interest rate and a market value of Juniper Networks
common stock of $22.62 per share, which was determined by using the average closing price of the Company’s
common stock over a five-day trading period beginning two days before and ending two days after the date the
transaction was announced on April 26, 2005. The Company also assumed $1.0 million in net liabilities. In 2006,
the Company recorded an additional $13.2 million cash escrow payment to the initial purchase price of
$123.1 million related to Redline’s indemnity obligations which expired in 2006. There were no escrow payments
in connection with the Redline acquisition during 2007. As of December 31, 2007, the Company had retained
$0.7 million in escrow to satisfy potential indemnity obligations.

Kagoor Acquisition: On May 1, 2005, the Company completed its acquisition of Kagoor. Kagoor was a
leading provider of session border control products for voice-over-Internet Protocol (VoIP) networking. The initial
purchase price for Kagoor included $58.2 million in cash and assumed stock options with an aggregate fair value of
$7.6 million. The stock options were valued using the Black-Scholes option pricing model with the inputs of 43%
for volatility, 1.58 years for expected life, 3.5% for risk-free interest rate and a market value of Juniper Networks
common stock of $21.64 per share, which was determined by using the average closing price of the Company’s
common stock over a five-day trading period beginning two days before and ending two days after the date the
transaction was announced on March 29, 2005. Excluded from the initial purchase price of $66.3 million is an
escrow payment of $6.8 million related to the indemnity obligations associated with this acquisition, $2.0 million of
which was paid in 2006. In February 2007, the Company distributed an additional $4.6 million to former Kagoor
stockholders upon final settlement of the escrow account.

In-Process Research & Development: The Company’s methodology for allocating the purchase price for
purchase acquisitions to in-process research and development (“IPR&D”) is determined through established
valuation techniques in the high-technology communications equipment industry. Projects that qualify as IPR&D
represent those that have not yet reached technological feasibility and have no alternative future use. IPR&D is
expensed upon acquisition. There was no IPR&D expense for the years ended December 31, 2007 and 2006. For the
year ended December 31, 2005, total IPR&D expense was $11.0 million in connection with the Funk, Peribit and
Kagoor acquisitions. There was no IPR&D from the Acorn and Redline acquisitions.

For Funk, these IPR&D efforts pertained to the development of Radius products including Steel-Belted Radius
(“SBR”), SBR High Availability (“HA”), and Mobile IP Module (“MIM”) II products. Funk’s IPR&D as of the
acquisition date also included development of the new versions for Endpoint Assurance, for Proxy (Remote
Control), and Odyssey product families. At the time of the acquisition, it was estimated that these development
efforts would be completed over the next four months at an estimated cost of approximately $0.9 million. These
development efforts have been completed as of December 31, 2007.

For Peribit, these IPR&D efforts included the development of the next versions of software for the Sequence
Reducer (“SR”) family, Sequence Mirror (“SM”) family, the Central Management System (“CMS”) products, as
well as a hardware program for both the SR and SM families. At the time of the acquisition, it was estimated that
these development efforts would be completed over the next twelve months at an estimated cost of approximately
$2.3 million. These development efforts have been completed as of December 31, 2007.

For Kagoor, these IPR&D efforts included a variety of signaling protocols and next generation products and
operating systems. At the time of the acquisition, it was estimated that these development efforts would be
completed over the next eight months at an estimated cost of approximately $0.8 million. These development efforts
have been completed as of December 31, 2007.

Deferred Stock-Based Compensation: Unvested stock options valued at $13.2 million, $3.8 million, and
$2.0 million were issued for the Peribit, Redline, and Kagoor acquisitions, respectively. The unvested portion of the
intrinsic value of the replacement stock options, established as of the acquisition date, has been allocated to deferred
compensation in the purchase price allocation and is being amortized to expense using the graded-vesting method
over the remaining vesting period.

The Company performed a goodwill impairment review as of November 1, 2007 and concluded that there was
no impairment in 2007. In 2006, the Company concluded that the carrying value of goodwill for the SLT segment
was impaired and recorded an impairment charge of $1,280.0 million in operating expenses. There was no goodwill
impairment in 2005.

A significant portion of the goodwill was initially recorded based on stock prices at the time the related merger
agreements were executed and announced. The impairment of goodwill in 2006 was primarily attributable to the
decline in the Company’s market capitalization that occurred over a period of approximately six months prior to the
impairment review as of May 31, 2006 and, to a lesser extent, a decrease in the forecasted future cash flows used in
the income approach.

The first step of the 2006 impairment review was to compare the fair value of each reporting unit to its carrying
value, including the goodwill related to the respective reporting units. When performing the 2006 goodwill
impairment review, the Company determined that it had four reporting units at the time of the impairment
calculation, consisting of Infrastructure and Service, which are the same as the respective segments, as well as
Security and Application Acceleration which were the two components of SLT segment. The Company utilized an
external service provider to calculate the fair value of the reporting units using a combination of the income and
market approaches. The income approach requires estimates of expected revenue, gross margin and operating
expenses in order to discount the sum of future cash flows using each particular business’ weighted average cost of
capital. The Company’s growth estimates were based on historical data and internal estimates developed as part of
its long-term planning process. The Company tested the reasonableness of the inputs and outcomes of its discounted

83

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

cash flow analysis by comparing to available market data. In determining the carrying value of the reporting unit,
the Company allocated the fair values of shared tangible net assets to each reporting unit based on revenue derived
by that reporting unit. As the fair values of the Security and Application Acceleration reporting units were lower
than the allocated book values, goodwill was considered impaired. As a result, the Company performed step two of
the goodwill impairment calculation for those two reporting units within the SLT segment in order to calculate the
extent of the goodwill impairment.

During the second step of the 2006 goodwill impairment review, management calculated the fair value of the
Company’s tangible and intangible net assets with the assistance of an external service provider. Identified
intangible assets were valued specifically for each reporting unit tested. The difference between the calculated fair
value of each reporting unit and the sum of the identified net assets results in the residual value of goodwill. Future
impairment indicators, including declines in the Company’s market capitalization, could require additional
impairment charges.

In 2007, goodwill increased $33.9 million primarily due to payments of $32.8 million upon resolution of
acquisition related indemnity issues and the release of amount held in escrow funds, as well as the distribution, from
an escrow account, of approximately 0.8 million shares of its common stock, with an aggregate fair value of
$14.8 million, in connection with the resolution of certain indemnity obligations related to past acquisitions.
Additionally, goodwill increased by $1.0 million as the Company recorded the cumulative effect of applying FIN 48
in 2007. In 2006, the goodwill increase of $25.0 million was primarily attributable to the settlements of the
Company’s escrow obligations. The Company released from its escrow accounts 0.8 million shares of common
stock, with a total market value of $10.3 million, and $2.0 million of its restricted cash for the indemnity obligations
associated with past acquisitions. The Company also distributed $13.1 million of its restricted cash for the escrow
obligations associated with the acquisition of Redline. Goodwill increased in 2005 by $470.3 million from the
$469.9 million of goodwill acquired in the 2005 acquisitions and a $6.4 million settlement of the Company’s escrow
obligation partially offset by a decrease of $6.0 million to reflect the misclassified tax benefits from deductions from
stock options assumed in acquisitions.

Amortization expense related to finite-lived purchased intangible assets was $91.4 million, $97.3 million, and
$85.2 million in 2007, 2006, and 2005 respectively. Amortization expense of purchased intangible assets of $85.9 million
and $5.5 million were included in operating expenses and cost of product revenue in 2007. During 2007, the Company
had no impairment charges. During 2006, the Company recorded an impairment charge of $3.4 million in operating
expenses due to a significant decrease in forecasted revenues associated with session border control (“SBC”), Kagoor’s

There was no significant realized gain or loss from the sale of available-for-sale securities in 2007 and 2006.
There were realized losses from the sale of available-for-sale securities of $0.9 million in 2005. We generated cash
proceeds of $1,029.1 million, $632.1 million, and $805.0 million from sales and maturities of our available-for-sale
investments during 2007, 2006 and 2005, respectively.

As of December 31, 2007, the Company had approximately 60 investments that were in an unrealized loss
position. As of December 31, 2006 the Company had approximately 250 investments that were in an unrealized loss
position. The gross unrealized losses related to these investments were due to changes in interest rates. The
contractual terms of these investments do not permit the issuer to settle the securities at a price less than the
amortized cost of the investment. Given that the Company has the ability and intent to hold each of these
investments until a recovery of the fair values, which may be maturity, the Company does not consider these
investments to be other-than-temporarily impaired as of December 31, 2007 and 2006. The Company reviews its
investments to identify and evaluate investments that have an indication of possible impairment. The Company
aggregated its investments by category and length of time the securities have been in a continuous unrealized loss
position.

Government securities included governmental sponsored enterprises with an aggregate cost of $54.2 million,
an aggregate market value of $54.3 million, and an aggregate unrealized gain of $0.2 million as of December 31,
2007. As of December 31, 2006, government securities included governmental sponsored enterprises with an
aggregate cost of $207.1 million, an aggregate market value of $206.1 million, and an unrealized loss of
$1.0 million.

Minority Equity Investments

As of December 31, 2007 and 2006, the carrying values of the Company’s minority equity investments in
privately held companies of $23.3 million and $20.4 million, respectively, were included in other long-term assets
in the consolidated balance sheets. In 2007, 2006 and 2005, the Company invested a total of $4.1 million,
$7.3 million, and $11.0 million in privately-held companies, respectively.

In 2007, one of the Company’s minority equity investments completed an initial public offering (“IPO”). Upon
completion of the IPO, the Company reclassified the minority equity investment to available-for-sale investments
and realized a gain of $6.7 million, based upon the market value at the time of IPO and the Company’s cost basis,
during 2007. Subsequent to the IPO, the Company’s investment in this publicly traded entity is included in
available-for-sale investments. Available-for-sale investments are periodically adjusted to fair value through
comprehensive income. Realized gains and losses and declines in value judged to be other than temporary for
all available-for-sale investments are included in interest and other income in the consolidated statement of
operations. In 2005, the Company recognized a gain of $1.7 million due to a business combination of one of its
portfolio companies with a cost basis of $1.0 million and wrote down $0.4 million against its investment in one of
the privately held companies.

The Company’s minority equity investments in privately held companies are carried at cost as the Company
does not have a controlling interest and does not have the ability to exercise significant influence over these
companies. The Company adjusts its minority equity investments for any impairment if the fair value exceeds the
carrying value of the respective assets.

Restructuring Charges

Restructuring charges were based on Juniper Networks’ restructuring plans that were committed to by
management. Any changes in the estimates of executing the approved plans will be reflected in the Company’s
results of operations. The following table shows changes in the restructuring liabilities during 2007 (in millions):

In 2007 the Company paid $0.9 million for facility charges associated with its restructuring plans initiated in
prior years. In June 2006, the Company implemented a restructuring plan that focused on some Infrastructure
segment product development cost reduction efforts and the discontinuation of its SBC product line. Approximately
$2.0 million including $0.6 million of severance charges for 33 employees was paid in 2006. In addition to the
payments relating to the 2006 plan, the Company paid $0.7 million for facility charges associated with its
restructuring plans initiated prior to 2006. As of December 31, 2007 and 2006, the restructuring reserve of
$0.6 million and $1.5 million, respectively, was related to future facility charges. Amounts related to the net facility
charge are included in other accrued liabilities and will be paid over the remaining respective lease term through
July 2008. The difference between the actual future rent payments and the net present value will be recorded as
operating expenses when incurred.

Acquisition Related Restructuring

Acquisition related reserves pertain to the restructuring reserves established in connection with the Company’s
past acquisitions. In conjunction with various acquisitions, the Company accrued for acquisition related restruc-
turing charges primarily related to severance and facility charges. As of December 31, 2007, approximately
$1.6 million remained unpaid, of which $0.6 million was recorded in other long-term liabilities in the consolidated
balance sheet. As of December 31, 2006, approximately $3.6 million remained unpaid, of which $1.5 million was
recorded in other long-term liabilities in the consolidated balance sheet.

During 2007, the Company reversed $0.3 million of its existing acquisition restructuring reserve primarily for
facility related charges. During 2006, the Company paid $3.0 million primarily for the facility related charges. In
addition, the Company reversed its existing acquisition restructuring reserve by $0.4 million that was previously
accrued for the Unisphere and NetScreen facilities. During 2005, the Company reversed its existing acquisition
related restructuring reserves by $6.9 million primarily due to changes in estimates of the previous accrual for the
NetScreen facility.

The following restructuring charges were based on Juniper Networks’ restructuring and acquisition related
restructuring plans that were committed to by management. Any changes to the estimates of executing the approved

Note 6. Debt

Senior Convertible Notes

In 2003, Juniper Networks received $392.8 million of net proceeds from an offering of $400.0 million aggregate
principal amount of Zero Coupon Convertible Senior Notes due June 15, 2008 (the “Senior Notes”). The Senior Notes
are senior unsecured obligations, rank on parity in right of payment with all of the Company’s existing and future senior
unsecured debt, and rank senior to all of the Company’s existing and future debt that expressly provides that it is
subordinated to the notes. The Senior Notes are convertible into shares of Juniper Networks common stock, subject to
certain conditions, at any time prior to maturity or their prior repurchase by Juniper Networks. The conversion rate is
49.6512 shares per each $1,000 principal amount of convertible notes, subject to adjustment in certain circumstances.
The Company reclassified its Senior Notes from long-term liabilities to short-term liabilities in the condensed
consolidated balance sheet during the second quarter of 2007 because the Senior Notes are due within the next 12 months.

The carrying amounts and fair values of the Senior Notes were (in millions):

Approximately $0.4 million of the Company’s Senior Notes was converted into common shares in 2007.
During 2006 and 2005, an immaterial amount of the Company’s Senior Notes was converted into common shares.

Credit Facility

In June 2007, the Company entered into a senior secured margin lending agreement with a third-party financial
institution for a maximum credit facility of $400.0 million, or 90% of the fair market value of the underlying
collateral, to establish a flexible draw down facility to fund additional stock repurchases, as necessary. This credit
facility bore a floating interest rate equal to the three-month USD LIBOR plus 40 basis points per annum and, if
utilized, would be secured by the Company’s publicly traded fixed income securities portfolio equivalent to 111%
of any outstanding balance. This credit facility was terminated on September 26, 2007. The Company did not utilize
this credit facility at any time.

Distributor Financing Arrangement

The Company recognized the sale of accounts receivable to the financing provider according to Financial
Accounting Standard No. 140, Accounting for Transfers of Financial Assets and Extinguishment of Liabilities, a
replacement of FAS 125. The Company introduced its distributor financing program in 2006 to strengthen its
channel business by promoting greater distributor volume and improved customer service. The program does not,
and is not intended to, affect the timing of revenue recognition because the Company only recognizes revenue upon
sell-through. Under the financing arrangements the proceeds from the financing provider are due to the Company
30 days from the sale of the receivable. The Company pays the financing provider a financing fee based on the

89

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

spread over LIBOR or SIBOR. In these transactions with a major financing provider, the Company has surrendered
control over the transferred assets. The accounts receivable have been isolated from the Company and put beyond
the reach of creditors, even in the event of bankruptcy. The purchaser of the accounts receivable balances has the
right to pledge or exchange the assets transferred. The Company does not maintain effective control over the
transferred assets through obligations or rights to redeem, transfer or repurchase the receivables after they have been
transferred.

Pursuant to the receivable financing arrangements for the sale of receivables, the Company sold net receivables
of $38.7 million during the years ended December 31, 2006 and $130.4 million during the year ended December 31,
2007, respectively. During the year ended December 31, 2007 and December 31, 2006, the Company received cash
proceeds, net of the financing fee, of $95.4 million and $24.0 million, respectively. The amounts owing by the
financing provider recorded as accounts receivable on the Company’s consolidated balance sheets as of
December 31, 2007 and December 31, 2006 were $40.4 million and $13.0 million, respectively.

The Company has determined that the portion of the receivable financed that has not been recognized as
revenue should be accounted for as a financing pursuant to EITF Issue 88-18, Sales of Future Revenues. As of
December 31, 2007 and December 31, 2006, the estimated amounts of cash received from the financing provider
that has not been recognized as revenue from its distributors was $10.0 million at December 31, 2007 and nil at
December 31, 2006.

Restricted Cash

Restricted cash as of December 31, 2007 consisted of escrow accounts required by certain 2005 acquisitions
and the Directors & Officers (“D&O”) trust. Juniper Networks established the D&O trust to secure its indem-
nification obligations to certain directors and officers arising from their activities as such in the event that the
Company does not provide or is financially incapable of providing indemnification. In 2007 the Company
distributed $11.5 million, $1.6 million, and $4.6 million of its restricted cash upon the settlement of certain
escrow obligations associated with the acquisitions of Funk, Acorn, and Kagoor, respectively. In 2007, the
Company also added $8.9 million to its D&O insurance trust to increase coverage due to the overall growth of the
Company. In 2006, the Company reduced restricted cash by $5.9 million as its deposit requirements for standby
letters of credits issued for facility leases was removed and distributed $13.1 million and $2.0 million of its
restricted cash upon the settlement of certain escrow obligations associated with the Redline and Kagoor

90

acquisitions, respectively. In 2005, the Company added $12.2 million, $2.5 million, $13.5 million and $6.9 million
to restricted cash for the escrow accounts established in connection with the acquisitions of Funk, Acorn, Redline
and Kagoor, respectively.

Operating Leases

Juniper Networks leases its facilities under operating leases that expire at various times, the longest of which
expires in 2016. Rental expense for 2007, 2006, and 2005, was approximately $48.7 million, $40.3 million, and
$36.4 million, respectively. Future minimum payments under the non-cancellable operating leases, net of com-
mitted sublease income, totaled $221.3 million as of December 31, 2007. Rent and related expenses paid to a related
party was $6.2 million, $4.9 million, and $4.4 million for 2007, 2006, and 2005, respectively.

Senior Notes

As of December 31, 2007, the Company’s Senior Notes had a carrying value of $399.5 million. The Senior
Notes are due on June 15, 2008. The Company reclassified its Senior Notes from long-term liabilities to short-term
liabilities in the condensed consolidated balance sheet during the second quarter of 2007 because the Senior Notes
are due within the next 12 months.

Purchase Commitments

In order to reduce manufacturing lead times and ensure adequate component supply, the contract manufac-
turers place non-cancelable, non-returnable (“NCNR”) orders for components based on the Company’s build
forecasts. As of December 31, 2007, there were NCNR component orders placed by the contract manufacturers with
a value of $102.8 million. The contract manufacturers use the components to build products based on the
Company’s forecasts and on purchase orders the Company has received from customers. Generally, the Company
does not own the components and title to the products transfers from the contract manufacturers to the Company and
immediately to the Company’s customers upon delivery at a designated shipment location. If the components go
unused or the products go unsold for specified periods of time, the Company may incur carrying charges or obsolete
materials charges for components that the contract manufacturers purchased to build products to meet the
Company’s forecast or customer orders. As of December 31, 2007, the Company had accrued $22.2 million
based on its estimate of such charges.

Tax Liabilities

As of December 31, 2007, the Company had $41.5 million included in long-term liabilities in the consolidated
balance sheet for unrecognized tax positions. At this time, the Company is unable to make a reasonably reliable
estimate of the timing of payments in individual years beyond 12 months due to uncertainties in the timing of tax
and audit outcomes.

Other Contractual Obligations

Other contractual obligations consist of the escrow amount of $2.2 million and bonus accrual of $0.7 million in
connection with past acquisitions for indemnity obligations expired in 2007, a software subscription requiring
payments of $5.0 million in both January 2008 and January 2009, and a joint development agreement requiring
quarterly payments of $3.5 million through January 2010.

Guarantees

The Company has entered into agreements with some of its customers that contain indemnification provisions
relating to potential situations where claims could be alleged that the Company’s products infringe the intellectual
property rights of a third-party.

Other guarantees or indemnification arrangements include guarantees of product and service performance and
standby letters of credit for certain lease facilities. The Company has not recorded a liability related to these
indemnification and guarantee provisions and its guarantees and indemnification arrangements have not had any
significant impact on the Company’s financial position, results of operations, or cash flows.

Legal Proceedings

The Company is subject to legal claims and litigation arising in the ordinary course of business, such as
employment or intellectual property claims, including the matters described below. The outcome of any such
matters is currently not determinable. Although the Company does not expect that any such legal claims or litigation
will ultimately have a material adverse effect on its consolidated financial position or results of operations, an
adverse result in one or more matters could negatively affect the Company’s results in the period in which they
occur.

Federal Derivative Lawsuits

Between May 24, 2006 and August 17, 2006, seven purported shareholder derivative actions were filed in the
United States District Court for the Northern District of California against us and certain of our current and former
officers and directors. The lawsuits allege that our officers and directors either participated in illegal back-dating of

94

Notes to Consolidated Financial Statements — (Continued)

stock option grants or allowed it to happen. On October 19, 2006, the Court ordered the consolidation of these
actions as In Re Juniper Derivative Actions, No. 06-03396, and appointed as the lead plaintiffs Timothy Hill,
Employer-Teamsters Local Nos. 175 & 505 Pension Trust Fund, and Indiana State District Council of Laborers and
HOD Carriers Pension Fund. Lead plaintiffs filed a consolidated complaint on April 11, 2007. The consolidated
complaint asserts causes of action for violations of federal securities laws, violations of California securities laws,
breaches of fiduciary duty, aiding and abetting breaches of fiduciary duty, abuse of control, corporate waste, breach
of contract, unjust enrichment, gross mismanagement, and insider selling and misappropriation of information. The
consolidated complaint also demands an accounting and rescission of allegedly improper stock option grants. The
Company has formed a Special Litigation Committee, consisting of directors Michael Rose and Michael Lawrie, to
determine whether it is in the best interests of Juniper Networks and its shareholders to pursue any of the claims
asserted in the derivative litigation. The Special Litigation Committee is authorized to pursue, settle or release such
claims.

State Derivative Lawsuits — California

On May 24, 2006 and June 2, 2006, two purported shareholder derivative actions were filed in the Santa Clara
County Superior Court in the State of California against the Company and certain of the Company’s current and
former officers and directors. These two actions were consolidated as In re Juniper Networks Derivative Litigation,
No. 1:06CV064294, by order dated June 20, 2006. An amended consolidated complaint was filed on April 9, 2007.
The amended consolidated complaint alleges that certain of the Company’s current and former officers and
directors either participated in illegal back-dating of stock options or allowed it to happen. The complaint asserts
causes of action for unjust enrichment, breach of fiduciary duties, abuse of control, gross mismanagement, waste of
corporate assets, insider selling and misappropriation of information, and violations of California securities laws.
Plaintiffs also demand an accounting and rescission of allegedly improper stock options grants, and a constructive
trust of proceeds derived from allegedly illicit stock options. The Company has formed a Special Litigation
Committee, consisting of directors Michael Rose and Michael Lawrie, to determine whether it is in the best interests
of Juniper Networks and its shareholders to pursue any of the claims asserted in the derivative litigation. The Special
Litigation Committee is authorized to pursue, settle or release such claims.

Federal Securities Class Action

On July 14, 2006 and August 29, 2006, two purported class actions were filed in the Northern District of
California against the Company and certain of the Company’s current and former officers and directors. On
November 20, 2006, the Court consolidated the two actions as In re Juniper Networks, Inc. Securities Litigation,
No. C06-04327-JW, and appointed the New York City Pension Funds as lead plaintiffs. The lead plaintiffs filed a
Consolidated Class Action Complaint on January 12, 2007, and filed an Amended Consolidated Class Action
Complaint on April 9, 2007. The Amended Consolidated Complaint alleges that the defendants violated federal
securities laws by manipulating stock option grant dates to coincide with low stock prices and issuing false and
misleading statements including, among others, incorrect financial statements due to the improper accounting of
stock option grants. The Amended Consolidated Complaint asserts claims for violations of the Securities Act of
1933 and the Securities Exchange Act of 1934 on behalf of all persons who purchased or otherwise acquired Juniper
Networks’ publicly traded securities from July 12, 2001 through and including August 10, 2006. On June 7, 2007,
the defendants filed a motion to dismiss certain of the claims, and a hearing was held on September 10, 2007. The
Court has not yet issued a ruling.

Calamore Proxy Statement Action

On March 28, 2007 an action titled Jeanne M. Calamore v. Juniper Networks, Inc., et al., No. C-07-1772-JW,
was filed by Jeanne M. Calamore in the Northern District of California against the Company and certain of the
Company’s current and former officers and directors. The complaint alleges that the proxy statement for the
Company’s 2006 Annual Meeting of Stockholders contained various false and misleading statements in that it failed

95

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

to disclose stock option backdating information. As a result, plaintiff seeks preliminary and permanent injunctive
relief with respect to the Company’s 2006 Equity Incentive Plan, including seeking to invalidate the plan and all
equity awards granted and grantable thereunder. On May 21, 2007, the Company filed a motion to dismiss and
plaintiff filed a motion for preliminary injunction. On July 19, 2007, the Court issued an order denying plaintiff’s
motion for a preliminary injunction and dismissing the complaint in its entirety with leave to amend. Plaintiff filed
an amended complaint on August 27, 2007, and defendants filed a motion to dismiss on October 9, 2007. Plaintiff
filed her opposition on December 21, 2007 and defendants filed their reply on January 25, 2008. A hearing was held
on February 11, 2008. The Court has not yet issued a ruling.

Settlement with the Securities and Exchange Commission (SEC)

On August 28, 2007, the Company announced that the Commissioners of the SEC authorized the settlement
between the Company and the SEC regarding the previously disclosed SEC inquiry into the Company historical
stock option granting practices. Without admitting or denying the allegations in the SEC’s complaint, the Company
agreed to settle the charges by consenting to a permanent injunction against any future violations of the antifraud,
reporting, books-and-records and internal control provisions of the federal securities laws. The SEC filed the
complaint, SEC v. Juniper Networks, Inc., Case No. C 07 4430-JW, in the Northern District of California on
August 28, 2007. The Company’s consent to entry of final judgment was also filed on August 28, 2007. No
monetary penalties were assessed against the Company in conjunction with this settlement. This settlement
concludes the SEC’s formal investigation of the company with respect to the Company’s historical stock option
granting practices. The Court entered the final judgment on December 7, 2007.

IPO Allocation Case

In December 2001, a class action complaint was filed in the United States District Court for the Southern
District of New York against the Goldman Sachs Group, Inc., Credit Suisse First Boston Corporation, FleetBoston
Robertson Stephens, Inc., Royal Bank of Canada (Dain Rauscher Wessels), SG Cowen Securities Corporation, UBS
Warburg LLC (Warburg Dillon Read LLC), Chase (Hambrecht & Quist LLC), J.P. Morgan Chase & Co., Lehman
Brothers, Inc., Salomon Smith Barney, Inc., Merrill Lynch, Pierce, Fenner & Smith, Incorporated (collectively, the
“Underwriters”), the Company and certain of the Company’s officers. This action was brought on behalf of
purchasers of the Company’s common stock in the Company’s initial public offering in June 1999 and the
Company’s secondary offering in September 1999.

Specifically, among other things, this complaint alleged that the prospectus pursuant to which shares of
common stock were sold in the Company’s initial public offering and the Company’s subsequent secondary offering
contained certain false and misleading statements or omissions regarding the practices of the Underwriters with
respect to their allocation of shares of common stock in these offerings and their receipt of commissions from
customers related to such allocations. Various plaintiffs have filed actions asserting similar allegations concerning
the initial public offerings of approximately 300 other issuers. These various cases pending in the Southern District
of New York have been coordinated for pretrial proceedings as In re Initial Public Offering Securities Litigation, 21
MC 92. In April 2002, plaintiffs filed a consolidated amended complaint in the action against the Company, alleging
violations of the Securities Act of 1933 and the Securities Exchange Act of 1934. Defendants in the coordinated
proceeding filed motions to dismiss. In October 2002, the Company’s officers were dismissed from the case without
prejudice pursuant to a stipulation. On February 19, 2003, the court granted in part and denied in part the motion to
dismiss, but declined to dismiss the claims against the Company.

In June 2004, a stipulation of settlement and release of claims against the issuer defendants, including the
Company, was submitted to the court for approval. On August 31, 2005, the court preliminarily approved the
settlement. In December 2006, the appellate court overturned the certification of classes in the six test cases that
were selected by the underwriter defendants and plaintiffs in the coordinated proceedings. Because class certi-
fication was a condition of the settlement, it was unlikely that the settlement would receive final Court approval. On

Notes to Consolidated Financial Statements — (Continued)

June 25, 2007, the Court entered an order terminating the proposed settlement based upon a stipulation among the
parties to the settlement. Plaintiffs have filed amended master allegations and amended complaints in the six focus
cases, which the defendants in those actions have moved to dismiss. Plaintiffs have also sought class certification in
the six focus cases, which the defendants in those actions have opposed. It is uncertain whether there will be any
revised or future settlement.

16(b) Demand

On October 3, 2007, a purported Juniper Networks shareholder filed a complaint for violation of Section 16(b)
of the Securities Exchange Act of 1934, which prohibits short-swing trading, against the Company’s IPO
underwriters. The complaint, Vanessa Simmonds v. The Goldman Sachs Group, et al., Case No. C07-01577, in
District Court for the Western District of Washington, seeks the recovery of short-swing profits. The Company is
named as a nominal defendant. No recovery is sought from the Company in this matter.

IRS Notices of Proposed Adjustments

The IRS has concluded an audit of the Company’s federal income tax returns for fiscal years 1999 and 2000.
During 2004, the Company received a Notice of Proposed Adjustment (“NOPA”) from the IRS. While the final
resolution of the issues raised in the NOPA is uncertain, the Company does not believe that the outcome of this
matter will have a material adverse effect on its consolidated financial position or results of operations. The
Company is also under routine examination by certain state and non-US tax authorities. The Company believes that
it has adequately provided for any reasonably foreseeable outcome related to these audits.

In conjunction with the IRS income tax audit, certain of the Company’s US payroll tax returns were examined
for fiscal years 1999 — 2001, and the Company received a second NOPA in the amount of $11.7 million for
employment tax assessments primarily related to the timing of tax deposits related to employee stock option
exercises. The Company agreed to settle this issue with the IRS through the appeals process for approximately
$2.7 million and made this payment in the second quarter of 2007.

In 2007, the IRS opened an examination of the Company’s U.S. federal income tax and employment tax returns
for the 2004 fiscal year. Subsequently, the IRS extended their examination of the Company’s employment tax
returns to include fiscal years 2005 and 2006. The Company has not received any NOPAs related to these audits.

Note 9. Stockholders’ Equity

Stock Repurchase Activities

In July 2004, the Company’s Board of Directors (“the Board”) authorized a stock repurchase program. This
program authorized repurchases of up to $250.0 million of the Company’s common stock. In 2006, the Company
repurchased 10,071,100 common shares at an average price of $18.51 per share, with an aggregate fair value of
$186.4 million, as part of this stock repurchase program. As of December 31, 2006, a total of 12,939,700 common
shares had been repurchased and retired since the inception of the program, equating to approximately $250.0 million
at an average price of $19.32 per share. The purchase price of the shares of the Company’s stock repurchased under
this program was reflected as a reduction to retained earnings.

In July 2006, the Board approved a new stock repurchase program (“2006 Stock Repurchase Program”)
authorizing the Company to repurchase up to $1.0 billion of Juniper Networks’ common stock under this program.
In February 2007, the Board approved an increase of $1.0 billion under this stock repurchase program. Coupled
with the prior authorization of $1.0 billion announced in July 2006, the Company is now authorized to repurchase up
to a total of $2.0 billion of its common stock under the 2006 Stock Repurchase Program. Purchases under the 2006
Stock Repurchase Program are made from time to time as permitted by securities laws and other legal requirements
and are subject to a review of the circumstances in place at the time. During 2007, the Company repurchased a total
of 69,443,946 shares of common stock via open market purchases at an average price of $23.37 per share, or a total

97

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

purchase price of $1,623.2 million, of which $1,622.7 million was reflected as an increase to accumulated deficit
and the remainder as a decrease to additional paid-in capital. Common stock repurchases under the program were
recorded based upon the settlement date of the applicable trade for accounting purposes. All common shares
repurchased under this program have been retired. As of December 31, 2007, the 2006 Stock Repurchase Program
had remaining authorized funds of $376.8 million.

Additional purchases under this stock repurchase program may be made from time to time and are subject to a
review of circumstances in place at the time. This program may be discontinued at any time. See Note 15 below for
discussion of our stock repurchase activity in 2008.

Stock Option Plans

Amended and Restated 1996 Stock Plan

The Company’s Amended and Restated 1996 Stock Plan (the “1996 Plan”) provided for the granting of
incentive stock options to employees and non-statutory stock options to employees, directors and consultants. On
November 3, 2005, the Board adopted an amendment to the 1996 Plan to add the ability to issue RSUs under the
1996 Plan. RSUs represent an obligation of the Company to issue unrestricted shares of common stock to the
grantee only when and to the extent that the vesting criteria of the award are satisfied. In the case of RSUs, vesting
criteria can be based on time or other conditions specified by the Board or an authorized committee of the Board.
However, until vesting occurs, the grantee is not entitled to any stockholder rights with respect to the unvested
shares. The Company had authorized 164,623,039 shares of common stock for issuance under the 1996 Plan.
Effective May 18, 2006, additional equity awards under the 1996 Plan have been discontinued and new equity
awards are being granted under the 2006 Equity Incentive Plan (the “2006 Plan”). Remaining authorized shares
under the 1996 Plan that were not subject to outstanding awards as of May 18, 2006 were canceled on May 18, 2006.
The 1996 Plan will remain in effect as to outstanding equity awards granted under the plan prior to May 18, 2006.

Under the 1996 Plan, incentive stock options were not permitted to be granted at an exercise price less than the
fair market value per share of the common stock on the date of grant. The Company has not granted incentive stock
options since June 1999. Non-statutory stock options were permitted to be granted at an exercise price determined
by the Board or a committee authorized by the Board. Vesting and exercise provisions were permitted to be
determined by the Board or a committee authorized by the Board. Options granted under the 1996 Plan generally
become exercisable over a four-year period beginning on the date of grant and have a maximum term of ten years.

2000 Nonstatutory Stock Option Plan

In July 2000, the Board adopted the Juniper Networks 2000 Nonstatutory Stock Option Plan (the “2000 Plan”).
The 2000 Plan provided for the granting of non-statutory stock options to employees, directors and consultants.
Non-statutory stock options were permitted to be granted under the terms of the plan at an exercise price determined
by the Board or a committee authorized by the Board. Vesting and exercise provisions were permitted to be
determined under the terms of the plan by the Board or an authorized committee of the Board. Options granted
under the 2000 Plan generally become exercisable over a four-year period beginning on the date of grant and have a
maximum term of ten years. The Company had authorized 90,901,437 shares of common stock for issuance under
the 2000 Plan. Effective May 18, 2006, additional equity awards under the 2000 Plan have been discontinued and
new equity awards are being granted under the 2006 Plan. Remaining authorized shares under the 2000 Plan that
were not subject to outstanding awards as of May 18, 2006 were canceled on May 18, 2006. The 2000 Plan will
remain in effect as to outstanding equity awards granted under the plan prior to May 18, 2006.

2006 Equity Incentive Plan

On May 18, 2006, the Company’s stockholders adopted the 2006 Plan to enable the granting of incentive stock
options, nonstatutory stock options, RSUs, restricted stock, stock appreciation rights, performance shares,

98

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

performance units, deferred stock units and dividend equivalents to the employees and consultants of the Company.
The 2006 Plan also provides for the automatic, non-discretionary award of nonstatutory stock options to the
Company’s non-employee member of the Board (“outside directors”).

The maximum aggregate number of shares authorized under the 2006 Plan is 64,500,000 shares of common
stock, plus the addition of any shares subject to outstanding options under the 1996 Plan and 2000 Plan that
subsequently expired unexercised after May 18, 2006 up to a maximum of 75,000,000 additional shares of the
common stock. To the extent a 2006 Plan award is settled in cash rather than stock, such cash payment shall not
reduce the number of shares available for issuance under the 2006 Plan. Performance shares, restricted stock or
RSUs with a per share or unit purchase price lower than 100% of market price of the Company’s common stock on
the day of the grant are counted against the plan share reserve as two and one-tenth shares for every one share
subject to the award. In the case of a restricted stock or performance share award, the entire number of shares subject
to such award would be counted against the plan share reserve at the time of grant. Such shares could be subject to
vesting provisions based on time or other conditions specified by the Board or an authorized committee of the
Board. The Company would have the right to repurchase unvested shares subject to a restricted stock or
performance share award if the grantee’s service to the Company terminated prior to full vesting of the award.
Until repurchased, such unvested shares would be considered outstanding for dividend, voting and other purposes.

Incentive and nonstatutory stock options may be granted at an exercise price of not less than the fair market
value of the Company’s common stock on the date such option is granted. The exercise price of an incentive stock
option granted to a 10% or greater stockholder may not be less than 110% of the fair market value of the common
stock on the grant date. Vesting and exercise provisions are determined by the Board, or an authorized committee of
the Board. Stock options granted under the 2006 Plan generally vest and become exercisable over a four year period.
Restricted stock, performance shares, RSUs or deferred stock units that vest solely based on continuing employ-
ment or provision of services will vest in full no earlier than the three year anniversary of the grant date. In the event
vesting is based on factors other than continued future provision of services, such awards will vest in full no earlier
than the one year anniversary of the grant date. Options granted under the 2006 Plan have a maximum term of seven
years from the grant date while incentive stock options granted to a 10% or greater stockholder have a maximum
term of five years from the grant date.

The 2006 Plan provides each non-employee director an automatic grant of an option to purchase 50,000 shares
of common stock upon the date on which such individual first becomes a director, whether through election by the
stockholders of the Company or appointment by the Board to fill a vacancy (the “First Option”). In addition, at each
of the Company’s annual stockholder meetings (i) each non-employee director who was a non-employee director on
the date of the prior year’s annual stockholder meeting shall be automatically granted an option to purchase
20,000 shares of common stock, and (ii) each non-employee director who was not an non-employee director on the
date of the prior year’s annual stockholder meeting shall receive an option to purchase a pro-rata portion of the
20,000 shares of the common stock determined by the time elapsed since the individual’s First Option grant (“the
Annual Option”). The First Option vests monthly over approximately three years from the grant date subject to the
non-employee director’s continuous service on the Board. The Annual Option shall vest monthly over approx-
imately one year from the grant date subject to the non-employee director’s continuous service on the Board. Under
the 2006 Plan, options granted to non-employee directors have a maximum term of seven years. No restricted stock,
stock appreciation right, performance unit, deferred stock unit or dividend equivalent has been issued as of
December 31, 2007. The Company had issued 21.3 million and 4.3 million of stock options and RSUs, respectively,
under the 2006 Plan as of December 31, 2007. The Company had issued 6.6 million and 0.7 million of stock options
and RSUs, respectively, under the 2006 Plan as of December 31, 2006.

Plans Assumed Upon Acquisition

In connection with past acquisitions, the Company assumed options and restricted stock under the stock plans
of the acquired companies. The Company exchanged those options and restricted stock for Juniper Networks’

99

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

options and restricted stock and, in the case of the options, authorized the appropriate number of shares of common
stock for issuance pursuant to those options. As of December 31, 2007, there were approximately 3.7 million
common shares subject to outstanding awards under plans assumed through past acquisitions. There were no shares
of restricted stock subject to repurchase as of December 31, 2007 and 2006. As of December 31, 2006, there were
approximately 8.8 million shares subject to outstanding awards under plans assumed through acquisitions. During
2007, there were no repurchases of shares of restricted common stock. During 2006, 333 shares of restricted
common stock were repurchased at an average price of $0.35 per share in connection with employee terminations.
During 2005, 6,517 shares of restricted common stock have been repurchased at an average price of $0.33 per share
in connection with employee terminations.

Equity Award Activity

In 2007, the Company granted RSUs covering approximately 2.9 million shares of common stock to its
employees under the 2006 Plan. In 2007, the Company also granted performance share awards to eligible executives
covering 0.7 million shares of common stock that vest in 2010 provided certain annual performance targets and
other vesting criteria are met. RSUs generally vest over a period of three or four years from the date of grant. Until
vested, RSUs and performance share awards do not have the voting rights of common stock and the shares
underlying the awards are not considered issued and outstanding. The Company expenses the cost of RSUs, which
is determined to be the fair market value of the shares of the Company’s common stock at the date of grant, ratably
over the period during which the restrictions lapse. In addition to RSUs and performance share awards, during 2007,
the Company also granted employee stock options covering 14.7 million shares of common stock under the 2006
Plan. The Company estimated the stock compensation expense for its performance share awards as of December 31,
2007 based on the vesting criteria and recorded $0.4 million in operating expenses for 2007.

The intrinsic value of options exercised was $291.7 million, $107.8 million, and $240.1 million for 2007, 2006
and 2005, respectively. This intrinsic value represents the difference between the fair market value of the
Company’s common stock on the date of the exercise and the exercise price of each option.

Total fair value of options vested during 2007 was $78.8 million. As of December 31, 2007, approximately
$161.4 million of total unrecognized compensation cost related to stock options is expected to be recognized over a
weighted-average period of 2.9 years. Approximately $44.0 million of this total unrecognized compensation cost
was estimated to be forfeited prior to the vesting of such awards and had been excluded from the preceding cost.

Extension of Stock Option Exercise Periods for Former Employees

The Company could not issue any securities under its registration statements on Form S-8 during the period in
which it was not current in its SEC reporting obligations to file periodic reports under the Securities Exchange Act
of 1934. As a result, during parts of 2006 and 2007, options vested and held by certain former employees of the
Company could not be exercised until the completion of the Company’s stock option investigation and the
Company’s public filings obligations had been met (the “trading black-out period”). The Company extended the
expiration date of these stock options to April 7, 2007, the end of a 30 — day period subsequent to the Company’s
filing of its required regulatory reports. As a result of the extensions, the fair values of such stock options had been
reclassified to current liabilities subsequent to the modification and were subject to mark-to-market provisions at
the end of each reporting period until the earlier of final settlement or April 7, 2007. Stock options covering
approximately 660,000 shares of common stock were scheduled to expire and could not be exercised as a result of
the trading black-out period restriction during the first quarter of 2007. The Company measured the fair value of
these stock options using the Black-Scholes-Merton option valuation model and recorded an expense of approx-
imately $4.3 million in the first quarter of 2007. In addition, the Company recorded an expense of $4.4 million in the
first quarter of 2007 associated with the approximately 1,446,000 shares covered by such options which had
exercise periods extended in 2006 as a result of the trading black-out period restriction. As of December 31, 2007,
all of these extended stock options were either exercised or expired un-exercised. All previously recorded liabilities
associated with such extensions were reclassified to additional paid-in capital by the second quarter of 2007.

Amendment of Certain Stock Options

In 2007, the Company completed a tender offer to amend certain options granted under the 1996 Plan and the
2000 Plan that had original exercise prices per share that were less than the fair market value per share of the
common stock underlying the option on the option’s grant date, as determined by the Company for financial
accounting purposes. Under this tender offer, employees subject to taxation in the United States and Canada had the
opportunity to increase their strike price on affected options to the appropriate fair market value per share on the
date of grant so as to avoid unfavorable tax consequences under United States Internal Revenue Code Section 409A
(“409A issue”) or Canadian tax laws and regulations. In exchange for increasing the strike price of these options, the
Company committed to make a cash payment to employees participating in the offer so as to make employees whole
for the incremental strike price as compared to their original option exercise price. In connection with this offer, the
Company amended options to purchase 4.3 million shares of its common stock and committed to make aggregate
cash payments of $7.6 million to offer participants and recorded such amount as operating expense in 2007.

In addition, the Company entered into a separate agreement with two executives in 2007 to amend their
unexercised stock options covering 0.1 million shares of the Company’s common stock in order to cure the 409A
issue associated with such stock options. As a result, the Company committed to make aggregate cash payments of
$0.4 million and recorded this payment liability as operating expense in 2007.

Acceleration of Unvested and “Out-of-the-Money” Employee Stock Options

On December 16, 2005, the Board approved the acceleration of the vesting of certain unvested and “out-of-the-
money” stock options that had an exercise price per share equal to or greater than $22.00, all of which were
previously granted under its stock option plans and that were outstanding on December 16, 2005. Options to
purchase approximately 21.2 million shares of common stock or 49.3% of the total outstanding unvested options on
December 16, 2005 were accelerated. The options accelerated excluded options previously granted to certain
employees, including all of the Company’s executive officers and its directors.

In addition, the acceleration of the unvested and “out-of-the-money” options was accompanied by restrictions
imposed on any shares purchased through the exercise of accelerated options. Those restrictions will prevent the
sale of any such shares prior to the date such shares would have originally vested had the optionee been employed on
such date, whether or not the optionee is actually an employee at that time.

104

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

The purpose of the acceleration was to enable the Company to avoid recognizing compensation expense
associated with these options in future periods in the Statements of Operations pursuant to FAS 123R. Under
FAS 123R, the Company has applied the expense recognition provisions relating to stock options beginning in the
first quarter of fiscal 2006. In approving the acceleration, the Company’s Board considered its impact on future
financial results, stockholder value and employee retention. The Board believes that the acceleration of the unvested
and “out-of-the-money” options was in the best interest of stockholders as it will reduce the Company’s reported
compensation expense in future periods in light of these accounting regulations. As a result of the acceleration, the
Company expected to reduce the pre-tax stock option expense it otherwise would have been required to record by
approximately $153.0 million, which was estimated at the time of the acceleration, subsequent to the adoption of
FAS 123R beginning in 2006. The acceleration of the vesting of these options did not result in a charge to the results
of operations in 2005.

Employee Stock Purchase Plan

In April 1999, the Board approved the adoption of Juniper Networks 1999 Employee Stock Purchase Plan (the
“Purchase Plan”). The Purchase Plan permits eligible employees to acquire shares of the Company’s common stock
through periodic payroll deductions of up to 10% of base compensation. Each employee may purchase no more than
6,000 shares in any twelve-month period, and in no event, may an employee purchase more than $25,000 worth of
stock, determined at the fair market value of the shares at the time such option is granted, in one calendar year. The
Purchase Plan is implemented in a series of offering periods, each six months in duration, or a shorter period as
determined by the Board. The price at which the common stock may be purchased is 85% of the lesser of the fair
market value of the Company’s common stock on the first day of the applicable offering period or on the last day of
the applicable offering period.

In January 2007, the Board approved a delay of the start of the next offering period from February 1, 2007 to
April 1, 2007. Such offering period ended on July 31, 2007. Compensation expense of $7.6 million was recorded in
2007 for stock costs associated with the Purchase Plan. For 2006, compensation expense related to the common
stock issued under the Purchase Plan was $6.6 million. Compensation expense for the Purchase Plan in the same
2005 periods was only required as a footnote disclosure prior to the adoption of FAS 123R. As a result of the
Company’s failure to file its Quarterly Reports on Form 10-Q for the second and third quarters of 2006, the
Company had suspended its employee payroll withholdings for the purchase of its common stock under the
Purchase Plan from August 2006 through March 2007.

Employees purchased approximately 0.6 million, 1.7 million, and 0.9 million shares of common stock through
the Purchase Plan at an average exercise price of $17.08, $13.06 and $19.96 per share during fiscal years 2007, 2006
and 2005, respectively. During 2006, the number of authorized shares under the Purchase Plan increased by
3,000,000 shares. As of December 31, 2007, approximately 7.1 million shares had been issued and 10.9 million
shares remained available for future issuance under the Purchase Plan. As of December 31, 2006, approximately
6.5 million shares had been issued and 8.5 million shares remained available for future issuance under the Purchase
Plan.

Common Stock Reserved for Future Issuance

As of December 31, 2007, Juniper Networks had reserved an aggregate of approximately 150.0 million shares
of common stock for future issuance under all its Stock Option Plans, the 1999 Employee Stock Purchase Plan and
for future issuance upon conversion of convertible senior notes.

Stock-Based Compensation

Valuation of Stock-Based Compensation

FAS 123R requires the use of a valuation technique, such as an option-pricing model, to calculate the fair value
of stock-based awards. The Company has elected to use the Black-Scholes-Merton option-pricing model, which
incorporates various assumptions including volatility, expected life, and risk-free interest rates. The expected
volatility is based on the implied volatility of market traded options on the Company’s common stock, adjusted for
other relevant factors including historical volatility of the Company’s common stock over the most recent period
commensurate with the estimated expected life of the Company’s stock options. The expected life of an award is
based on historical experience and on the terms and conditions of the stock awards granted to employees, as well as
the potential effect from options that had not been exercised at the time.

In 2006, the Company began granting stock option awards that have a contractual life of seven years from the
date of grant. Prior to 2006, stock option awards generally had a ten year contractual life from the date of grant. As a
result, the expected term assumption used in the year ended December 31, 2007 reflects the shorter contractual life
of the new option awards granted during the period.

The assumptions used and the resulting estimates of weighted-average fair value per share of options granted

and for employee stock purchases under the ESPP during those periods are summarized as follows:

In anticipation of adopting FAS 123R, the Company refined the variables used in the Black-Scholes-Merton
model during 2005. As a result, the Company refined its methodology of estimating the expected term to be more
representative of future exercise patterns. The Company also refined its computation of expected volatility by
considering the volatility of publicly traded options to purchase its common stock and its historical stock volatility.
The weighted average estimated fair value of employee stock options granted during 2007, 2006, and 2005 was
$8.03, $6.09 and $9.23 per option, respectively. The weighted average estimated fair value of shares granted under
the Employee Stock Purchase Plan during 2007, 2006, and 2005 was $6.52, $5.19 and $6.36 per share, respectively.

Convertible Preferred Stock

There are 10,000,000 shares of convertible preferred stock with a par value of $0.00001 per share authorized

for issuance. No preferred stock was issued and outstanding as of December 31, 2007 and 2006.

Note 10.

401(k) Plan

Juniper Networks maintains a savings and retirement plan qualified under Section 401(k) of the Internal
Revenue Code of 1986, as amended. Employees meeting the eligibility requirement, as defined, may contribute up

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

to the statutory limits of the year. The Company has matched employee contributions since January 1, 2001.
Effective on January 1, 2005, the Company increased the match from 50% to 100% of eligible pay, up to an annual
maximum of $2,000. Effective January 1, 2007, the Company matches 25% of all employee contributions. All
matching contributions vest immediately. The Company’s matching contributions to the plan totaled $9.5 million,
$5.8 million, and $5.1 million in 2007, 2006, and 2005, respectively.

Note 11. Segment Information

The Company’s chief operating decision maker (“CODM”) and senior management team (together, “man-
agement”) allocate resources and assess performance based on financial information by the Company’s business
groups which are categorized into the following three reportable segments: Infrastructure, SLT, and Service. For
arrangements with both Infrastructure and SLT products, revenue is attributed to the segment based on the
underlying purchase order, contract or sell-through report.

The Infrastructure segment includes products from the E-, M-, T- and MX-series router product families as
well as the circuit-to-packet products. The SLT segment consists primarily of Firewall virtual private network
(“Firewall”) systems and appliances, secure sockets layer virtual private network (“SSL”) appliances, intrusion
detection and prevention appliances (“IDP”), application front end platforms, the J-series router product family and
wide area network (“WAN”) optimization platforms. The Service segment delivers world-wide services to
customers of the Infrastructure and the SLT segments.

The primary financial measure used by management in assessing performance and allocating resources to the
segments is management operating income, which includes certain cost of revenues, research and development
expenses, sales and marketing expenses, and general and administrative expenses. Direct costs and operating
expenses, such as standard costs, research and development, and product marketing expenses, are generally applied
to each segment. Indirect costs, such as manufacturing overhead and other cost of sales, are allocated based on
standard costs. Indirect operating expenses, such as sales, marketing, business development, and general and
administrative expenses are generally allocated to each segment based on factors including headcount and revenue.
The CODM does not allocate stock-based compensation, amortization, impairment, gain or loss on minority equity
investments, interest income and expense, other income and expense, income taxes, as well as certain other charges
to segments. With management’s organizational alignment initiatives and the ever-evolving business environment
such as changes in products or markets, acquisitions, long-term growth strategies, and the experience and
responsibilities of the senior executives in charge, the Company may reorganize its segments consistent with
corresponding changes in its organizational structure in 2008.

The Company tracks assets by physical location. The majority of the Company’s assets, including property and
equipment, as of December 31, 2007 and 2006 were attributable to its U.S. operations. Although management
reviews asset information on a corporate level and allocates depreciation expense by segment, the CODM does not
review asset information on a segment basis.

Note 12. Net Income Per Share

Basic net income per share is computed by dividing income available to common stockholders by the weighted
average number of common shares outstanding for that period. Diluted net income per share is computed giving
effect to all dilutive potential shares that were outstanding during the period. Dilutive potential common shares
consist of incremental common shares subject to repurchase, common shares issuable upon exercise of stock
options, and shares issuable upon conversion of the Subordinated Notes. The following table presents the
calculation of basic and diluted net income (loss) per share (in millions, except per share data):

Notes to Consolidated Financial Statements — (Continued)

For 2006, the Company excluded 34.6 million common stock equivalents consisting of convertible debt,
outstanding stock options, RSUs and shares subject to repurchase from the calculation of diluted loss per share
because all such securities were anti-dilutive due to the net loss in the year. For the years ended 2007, 2006, and
2005, approximately 11.5 million, 51.1 million, and 28.8 million common stock equivalents were not included in
the computation of diluted earnings per share because the effect would have been anti-dilutive.

As of December 31, 2007 and 2006, the Company had a valuation allowance on its U.S. domestic deferred tax
assets of approximately $34.3 million and $38.7 million, respectively, which relates to capital losses that will carry
forward to offset future capital gains.

The valuation allowance decreased $4.4 million and $1.9 million in the years ended December 31, 2007 and
2006, respectively. The 2007 reduction was attributable primarily to the reversal of investment losses previously

Notes to Consolidated Financial Statements — (Continued)

disallowed for income tax purposes and mark-to-market of the Company’s investments. The 2006 reduction was
attributable to use of capital losses carryovers.

As of December 31, 2007, the Company had federal and California net operating loss carry-forwards of
$28.7 million and $8.5 million, respectively. The Company also had federal and California tax credit carry-forwards
of approximately $14.3 million and $84.0 million, respectively. Approximately $14.3 million of the federal tax
credit carryforwards and $10.8 million of the California tax credit carryforwards will be credited to additional paid
in capital when utilized on the Company’s income tax returns since they have not met the realization criteria of
FAS 123R. Unused net operating loss carry-forwards and research and development tax credit carryforwards will
expire at various dates beginning in the years 2012 and 2022, respectively. The California tax credits carry forward
indefinitely.

The Company provides U.S. income taxes on the earnings of foreign subsidiaries unless the subsidiaries’
earnings are considered indefinitely reinvested outside of the United States. The Company has made no provision
for U.S. income taxes on approximately $436.9 million of cumulative undistributed earnings of certain foreign
subsidiaries through December 31, 2007 because it is the Company’s intention to permanently reinvest such
earnings. If such earnings were distributed, the Company would accrue additional income taxes expense of
approximately $130.9 million. These earnings are considered indefinitely invested in operations outside of the
U.S. as we intend to utilize these amounts to fund future expansion of our international operations.

The Company adopted the provisions of FIN 48 on January 1, 2007, the first day of fiscal 2007. The cumulative
effect of applying FIN 48 was a $19.2 million increase to the opening balance of accumulated deficit as of January 1,
2007 and a $1.0 million increase to goodwill. As of December 31, 2007, the total amount of gross unrecognized tax
benefits was $94.7 million, of which approximately $79.3 million, if recognized, would affect the effective tax rate.

In accordance with the Company’s accounting policy, it recognizes accrued interest and penalties related to
unrecognized tax benefits as a component of tax expense in the consolidated statement of operations. This policy
did not change as a result of the adoption of FIN 48. As of the date of adoption, the Company had accrued interest
expense and penalties related to unrecognized tax benefits of $4.1 million. As of December 31, 2007, the Company
accrued interest expense and penalties related to unrecognized tax benefits of $5.9 million within other long-term
liabilities in the consolidated balance sheets. The Company recorded net interest expense of $1.7 million in its
consolidated income statements during 2007.

It is reasonably possible that the amount of the liability for unrecognized tax benefits may change within the
next 12 months due to audit examinations. However, an estimate of the range of possible change cannot be made at
this time due to the high uncertainty of the resolution of and/or closure on open audits.

Juniper Networks, Inc.

Notes to Consolidated Financial Statements — (Continued)

The Company conducts business globally and, as a result, Juniper Networks or one or more of its subsidiaries
files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal
course of business the Company is subject to examination by taxing authorities throughout the world, including
such major jurisdictions as Ireland, Hong Kong, U.K., France, Germany, The Netherlands, Japan, China, Australia,
and the U.S. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or
non-U.S. income tax examinations for years before 2003, although carryforward attributes that were generated
prior to 2003 may still be adjusted upon examination by the IRS if the attributes either have been or will be used in a
future period.

The Company is currently under examination by the IRS for the 2004 tax year and by the German tax
authorities for the 2005 tax year. Additionally, the Company has not reached a final resolution with the IRS on an
adjustment it proposed for the 1999 and 2000 tax years. The Company was not under examination by any other
major jurisdictions in which the Company files its income tax returns as of December 31, 2007. It is possible that the
amount of the liability for unrecognized tax benefits may change within the next 12 months. However, an estimate
of the range of possible change cannot be made at this time. We have provided for uncertain tax positions that
require a FIN 48 liability.

American Jobs Creation Act of 2004 — Repatriation of Foreign Earnings

In 2005, the Company’s Chief Executive Officer and Board of Directors approved and repatriated $225.0 mil-
lion in foreign earnings under a domestic reinvestment plan in accordance with the American Jobs Creation Act of
2004 (“Jobs Act”). The Company recorded a net tax benefit in 2005 of $19.7 million related to this repatriation
dividend. The net tax benefit consists of a federal and state tax provision, net of federal benefit, of $9.7 million,
offset by a tax benefit of $29.4 million related to an adjustment of deferred tax liabilities on un-repatriated earnings.

Note 15. Subsequent Events

Stock Repurchases

In February 2008, the Company repurchased 2.2 million shares of its common stock, for $53.1 million at an
average purchase price of $24.61 per share, under its 2006 Stock Repurchase Program. As of the report filing date,
the Company’s 2006 Stock Repurchase Program had remaining authorized funds of $323.8 million. Purchases
under this plan are subject to a review of the circumstances in place at the time. Acquisitions under the share
repurchase program may be made from time to time as permitted by securities laws and other legal requirements.
The program may be discontinued at any time.

Phase Out of DX Products

In January 2008, the Company announced its plan to phase out its DX product line. The action has no material
impact on the Company’s consolidated results of operations, cash flows, and financial condition for the year ended
December 31, 2007.

ITEM 9A. Controls and Procedures

(a) Management’s Annual Report on Internal Control Over Financial Reporting: Please see Management’s
Annual Report on Internal Control over Financial Reporting under Item 8 on page 62 of this Form 10-K, which
report is incorporated herein by reference.

(b) For the “Report of Independent Registered Public Accounting Firm,” please see the report under Item 8 on

page 65 of this Form 10-K, which report is incorporated herein by reference.

Evaluation of Disclosure Controls and Procedures

Attached as exhibits to this report are certifications of our CEO and CFO, which are required in accordance
with Rule 13a-14 of the Securities Exchange Act of 1934, as amended. This “Controls and Procedures” section
includes information concerning the controls and controls evaluation referred to in the certifications, and it should
be read in conjunction with the certifications for a more complete understanding of the topics presented.

We carried out an evaluation, under the supervision and with the participation of our management, including
the CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures, as
defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended. Based upon that
evaluation, the CEO and CFO concluded that, as of the end of the period covered in this report, our disclosure
controls and procedures were effective to ensure that information required to be disclosed by the company in reports
that it files under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the
time periods specified in Securities and Exchange Commission rules and forms, and that material information
relating to our consolidated operations is made known to our management, including the CEO and CFO,
particularly during the period when our periodic reports are being prepared.

Changes in Internal Controls

In 2007, we initiated a multi-year implementation to upgrade certain key internal IT systems, including our
company-wide human resources management system, customer relationship management (“CRM”) system and our
enterprise resource planning (“ERP”) system. This project is the result of our normal business process to evaluate
and upgrade or replace our systems software and related business processes to support our evolving operational
needs. There were no changes in our internal control over financial reporting that occurred during the fourth quarter
of 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial
reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including the CEO and CFO, does not expect that our disclosure controls or our internal
control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well
designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will
be met. Our controls and procedures are designed to provide reasonable assurance that our control system’s
objective will be met and our CEO and CFO have concluded that our disclosure controls and procedures are
effective at the reasonable assurance level. The design of a control system must reflect the fact that there are
resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the
inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that mis-
statements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the
company have been detected. These inherent limitations include the realities that judgments in decision-making can
be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by
the individual acts of some persons, by collusion of two or more people, or by management override of the controls.
The design of any system of controls is based in part on certain assumptions about the likelihood of future events.
Projections of any evaluation of the effectiveness of controls in future periods are subject to risks. Over time,

116

controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with
policies or procedures.

(a) For these ratios, “earnings” represents (i) income before taxes before adjustment for minority interests in

equity investees and (ii) fixed charges.

(b) The pre-tax losses from continuing operations for the year end December 31, 2006 are not sufficient to cover
fixed charges by a total of approximately $897.0 million. As a result, the ratio of earnings to fixed charges has
not been computed for this period.

(c) Estimated interest on tax liabilities of $2.2 million, $1.3 million $1.7 million, $1.2 million and $0.9 million was
not included in total fixed charges for 2007, 2006, 2005, 2004 and 2003, respectively, as the Company classified
such interest as part of its income tax provision before and after the adoption of Financial Accounting Standards
Board (“FASB”) Interpretation No. 48, Accounting for Uncertainty in Income Taxes, on January 1, 2007.
