     and warrants as of the date hereof to each Purchaser that:

     2.1 The Company has been duly incorporated and is an existing corporation
in good standing under the laws of the State of Delaware, with requisite
corporate power and authority to own its properties and conduct its business as
presently conducted. The Company is duly qualified to do business as a foreign
corporation in good standing in all other U.S. jurisdictions in which its
ownership or lease of property or the conduct of its business requires such
qualification, except where the failure to be so qualified would not have a
material adverse effect on the condition (financial or other), business,
properties or results of operations of the Company and its subsidiaries, taken
as a whole (hereinafter, a "Material Adverse Effect"). The Company has furnished
representatives of the Purchasers with correct and complete copies of the
charter and by-laws of the Company, both as amended and currently in effect.

     2.2 Each subsidiary of the Company has been duly incorporated and is an
existing corporation in good standing under the laws of the jurisdiction of its
incorporation, with corporate power and authority to own its properties and
conduct its business as presently conducted. Each subsidiary of the Company is
duly qualified to do business as a foreign corporation in good standing in all
other U.S. jurisdictions in which its ownership or lease of property or the
conduct of its business requires such qualification, except where the failure to
be so qualified would not have a Material Adverse Effect; all of the issued and
outstanding capital stock of each subsidiary of the Company has been duly
authorized and validly issued and is fully paid and nonassessable and is owned
of record by the Company.

     2.3 As of March 31, 2002, the authorized capital stock of the Company
consists of: (i) one hundred ninety-five million (195,000,000) shares of Common
Stock and (ii) five million (5,000,000) shares of Preferred Stock. As of May 15,
2002, forty-seven million six hundred ninety-eight thousand one hundred
thirty-eight (47,698,138) shares of Common Stock have been issued and are
outstanding and sixty-three thousand six hundred thirty-seven (63,637) shares of
Preferred Stock are issued and outstanding. As of May 15, 2002, thirty-one
thousand (31,000) shares of Common Stock are held in the Company's treasury. As
reflected in the Company's records as of May 15, 2002, other than with respect
to an aggregate of twenty-one million nine hundred forty-eight thousand three
hundred eighty-two (21,948,382) shares of Common Stock reserved for issuance
under the Company's equity incentive plans and warrants to purchase an aggregate
of two thousand (2,000) shares of Common Stock. There are no outstanding
options, warrants, rights (including conversion or preemptive rights and rights
of first refusal),

<PAGE>

proxy or stockholder agreements, or agreements of any kind for the purchase or
acquisition from the Company of any of its equity securities.

     2.4 The Offered Securities, and the shares of Common Stock issuable upon
conversion of the Offered Securities (the "Conversion Shares"), and all
outstanding shares of capital stock of the Company have been duly authorized;
all outstanding shares of capital stock of the Company are, and, when the
Offered Securities have been delivered and paid for in accordance with this
Agreement on the Closing Date, and, when the Conversion Shares have been
delivered in accordance with the terms of the Certificate of Designations, such
Offered Securities and Conversion Shares will have been, validly issued, fully
paid and nonassessable. None of the Offered Securities or Conversion Shares are
subject to any preemptive right or any right of refusal.

     2.5 No consent, approval, authorization, or order of, or filing with, any
governmental agency or body or any court is required for the consummation of the
transactions contemplated by this Agreement in connection with the issuance and
sale of the Offered Securities or the Conversion Shares by the Company, except
for the filing of a Form D with the Securities and Exchange Commission (the
"SEC") under the Securities Act of 1933, as amended (the "Securities Act"), and
such as may be required under state securities laws.

     2.6 This Agreement has been duly authorized, executed and delivered by the
Company. All corporate action on the part of the Company and its stockholders,
directors and officers necessary for the authorization, execution and delivery
of this Agreement, the performance of all the Company's obligations hereunder
and for the authorization, issuance or reservation for issuance, sale and
delivery of the Offered Securities or the Conversion Shares has been taken. This
Agreement constitutes the legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms, subject to (i)
laws of general application relating to bankruptcy, insolvency and the relief of
debtors, (ii) rules of law governing specific performance, injunctive relief and
other equitable remedies, and (iii) the limitations imposed by applicable
federal or state securities laws on the indemnification provisions contained in
this Agreement.

     2.7 The execution, delivery and performance of this Agreement, and the

result in a breach or violation of (i) any of the terms and provisions of the
charter or bylaws of the Company or any of its subsidiaries, nor (ii) any of the
terms and provisions of, or constitute a default under any statute, rule,
regulation or order of any governmental agency or body or any court, domestic or
foreign, having jurisdiction over the Company or any subsidiary of the Company
or any of their properties, or any agreement or instrument to which the Company
or any such subsidiary is a party or by which the Company or any such subsidiary
is bound or to which any of the properties of the Company or any such subsidiary
is subject (except where such breaches, violations or defaults individually or
in the aggregate would not have a Material Adverse Effect). The Company has full
power and authority to authorize, issue and sell the Offered Securities or the
Conversion Shares as contemplated by this Agreement.

     2.8 There have been no investment bankers, brokers or finders used by the
Company or its affiliates in connection with the transactions contemplated by
this Agreement and no persons or entities are entitled to a fee or compensation
in respect thereof.

     2.9 The Company and its subsidiaries have good and marketable title to all
real properties and all other properties and assets owned by them that are
material to the operation of the Company's business, in each case free from
liens, encumbrances and defects that would materially affect the value thereof
or materially interfere with the use made or to be made thereof by them; and the
Company and its subsidiaries hold any leased real or personal property that are
material to the operation of the Company's business under valid and enforceable
leases with no exceptions that would materially interfere with the use made or
to be made thereof by them.

     2.10 The Company and its subsidiaries possess adequate certificates,
authorities or permits issued by appropriate governmental agencies or bodies
necessary to conduct the business now operated by them and have not received any
notice of proceedings relating to the revocation or modification of any such
certificate, authority or permit that, if determined adversely to the Company or
any of its subsidiaries, would individually or in the aggregate have a Material
Adverse Effect.

     2.11 There are no pending actions, suits or proceedings against or
affecting the Company, any of its subsidiaries or any of their respective
properties or any director, officer or employee (related to any such person's
services as a director, officer or employee of the Company) that, if determined
adversely to the Company or any of its subsidiaries, would individually or in
the aggregate have a Material Adverse Effect, or would materially and adversely
affect the ability of the Company to perform its obligations under this
Agreement, or which are otherwise material in the context of the sale of the
Offered Securities and, to the Company's knowledge, no such actions, suits or
proceedings are threatened or contemplated. The Company has not initiated and
has no plan to initiate any action, suit or proceeding that, if decided
adversely to the Company, would, individually or in the aggregate, result in a
Material Adverse Effect.

     2.12 The Company has made available to representatives of the Purchasers
all registration statements, proxy statements and other statements, reports,
schedules, forms and other documents filed by the Company with SEC since January
1, 2002, including copies of all the exhibits referenced therein (the "SEC
Documents"). All statements, reports, schedules, forms and other documents
required to have been filed by the Company with the SEC since January 1, 2002
have been so filed. As of their respective dates (or, if amended or superseded
by a filing prior to the date of this Agreement, then on the date of such
amendment or superseding filing): (i) each of the SEC Documents complied in all
material respects with the applicable requirements of the Securities Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as the case
may be; and (ii) none of the SEC Documents contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     2.13 The financial statements included in the SEC Documents present fairly
the financial position of the Company and its consolidated subsidiaries as of
the dates shown and

<PAGE>

their results of operations and cash flows for the periods shown, and such
financial statements have been prepared in conformity with the generally
accepted accounting principles in the United States applied on a consistent
basis (except as may be indicated in the notes to such financial statements or,
in the case of unaudited statements, as permitted by Form 10-Q of the SEC, and
except that the unaudited financial statements may not have contained footnotes
and were subject to normal and recurring year-end adjustments which were not, or
are not reasonably expected to be, individually or in the aggregate, material in
amount), complied as to form in all material respects with the published rules
and regulations of the SEC applicable thereto.

     2.14 The Company and its subsidiaries own or possess, or can acquire on
reasonable terms, sufficient legal rights to all material patents, patent
rights, licenses, inventions, copyrights, know-how (including trade secrets and
other unpatented and/or unpatentable propriety or confidential information,
systems or procedures), trademarks, service marks and trade names currently
employed by them in connection with the business now operated by them, and
neither the Company nor any of its subsidiaries has received any notice of
infringement of or conflict with asserted rights of others with respect to any
of the foregoing that, individually or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, would have a Material Adverse Effect.

     2.15 Neither the Company nor any affiliate (as defined in Rule 501(b) of
Regulation D under the Securities Act) (an "Affiliate") of the Company has,
directly, or through any agent, (a) sold, offered for sale, solicited any offers
to buy or otherwise negotiated in respect of, any security (as defined in the
Securities Act) which is or will be integrated with the sales of the Offered
Securities in a manner that would require the registration under the Securities
Act of the Offered Securities; or (b) offered, solicited offers to buy or sold
the Offered Securities in any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Securities Act)
or in any manner involving a public offering within the meaning of Section 4(2)
of the Securities Act; and the Company will not engage in any of the actions
described in subsections (a) and (b) of this paragraph.

     2.16 Subject to the accuracy of each of the Purchaser's representations
herein, it is not necessary in connection with the offer, sale and delivery of
the Offered Securities to the several Purchasers in the manner contemplated by
this Agreement to register the Offered Securities under the Securities Act.

     2.17 The issuance of the Offered Securities and the Conversion Shares,
neither individually nor in the aggregate, constitute an anti-dilution event for
any existing securityholders of the Company, other than the holders of the
Company's Series A Preferred Stock who will be entitled to a full-ratchet
anti-dilution adjustment, pursuant to which such securityholders would be
entitled to additional securities or a reduction in the applicable conversion
price or exercise price of any securities due to any issuance proposed to be
conducted hereunder.

     2.18 The information contained in this Agreement and the SEC documents with
respect to the business, operations, assets, results of operations and financial
condition of the Company, and the transactions contemplated by this Agreement,
are true and complete in all material respects and do not omit to state any
material fact or facts necessary in order to make

<PAGE>

the statements therein, in light of the circumstances under which they were
made, not misleading.

Section 3. Representation and Warranties of the Purchasers. Each Purchaser
hereby, severally and not jointly, represents and warrants to the Company, as of
the date hereof, as follows:

     3.1 If such Purchaser is an entity, such Purchaser is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization and has all requisite limited partnership, or other power and
authority to consummate the transactions contemplated hereby

     3.2 Such Purchaser has full limited partnership, or other power and
authority to execute and deliver this Agreement and to perform its obligations
hereunder. This Agreement constitutes the legal, valid and binding obligation of
such Purchaser, enforceable against such Purchaser in accordance with its terms,
subject to (a) laws of general application relating to bankruptcy, insolvency
and the relief of debtors, (b) rules of law governing specific performance,
injunctive relief and other equitable remedies, and (c) the limitations imposed
by applicable federal or state securities laws on the indemnification provisions
contained in this Agreement.

     3.3 The execution, delivery and performance of this Agreement, and the
purchase and acceptance of the Offered Securities by such Purchaser will not
result in a breach or violation of any of the terms and provisions of, or
constitute a default under any statute, rule, regulation or order of any
governmental agency or body or any court, domestic or foreign, having
jurisdiction over such Purchaser or any subsidiary of such Purchaser or any of
their properties, or any material agreement or instrument to which such
Purchaser or any such subsidiary is a party or by which such Purchaser or any
such subsidiary is bound or to which any of the properties of such Purchaser or
any such subsidiary is subject, or the charter, by-laws, or other governing
documents of such Purchaser or any such subsidiary (except where any such
breaches, violations or defaults individually or in the aggregate would not have
a material adverse effect on Purchaser's ability to perform this Agreement).

     3.4 Investment Representations.

          (a) Such Purchaser is sophisticated in transactions of this type and
capable of evaluating the merits and risks of the transactions described herein
and has the capacity to protect its own interests. Such Purchaser has not been
formed solely for the purpose of entering into the transactions described herein
and is acquiring the Offered Securities for investment for its own account, not
as a nominee or agent, and not with the view to, or for resale, distribution
thereof, in whole or in part.

          (b) Such Purchaser has not and does not intend to enter into any
contract, undertaking, agreement or arrangement with any person or entity to
sell, transfer or pledge the Offered Securities, other than to an affiliate,
partner or former partner of such Purchaser in compliance with the Securities
Act.

          (c) Such Purchaser acknowledges its understanding that the Company
intends to sell the Offered Securities pursuant to a private placement exempt
from registration under the

<PAGE>

Securities Act. In furtherance thereof, such Purchaser represents and warrants
that it is an "accredited investor" as that term is defined in Rule 501 of
Regulation D under the Securities Act, has the financial ability to bear the
economic risk of its investment, has adequate means for providing for its
current needs and personal contingencies and has no need for liquidity with
respect to its investment in the Company.

          (d) Such Purchaser agrees that it shall not sell or otherwise transfer
any of the Offered Securities without registration under the Securities Act,
pursuant to Rule 144 (or any successor rule) under the Securities Act or
pursuant to an opinion of counsel reasonably satisfactory to the Company that no
violation of the Securities Act will be involved in such transfer. Such
Purchaser fully understands that none of the Offered Securities have been
registered under the Securities Act or under the securities laws of any
applicable state or other jurisdiction and, therefore, cannot be resold,
pledged, assigned or otherwise disposed of unless subsequently registered under
the Securities Act and under the applicable securities laws of such states or
jurisdictions or an exemption from such registration is available. Such
Purchaser understands that the Company is under no obligation to register the
Offered Securities on its behalf with the exception of certain registration
rights set forth herein. Such Purchaser understands the lack of liquidity and
restrictions on transfer of the Offered Securities and that this investment is
suitable only for a person or entity of adequate financial means that has no
need for liquidity of this investment and that can afford a total loss of its
investment.

     3.5 There is no legal, administrative, arbitration or other action or
proceeding or governmental investigation pending, or to the knowledge of such
Purchaser threatened, against such Purchaser that challenges the validity or
performance of this Agreement or which, if successful, could hinder or prevent
such Purchaser from performing its obligations hereunder.

     3.6 There have been no investment bankers, brokers or finders used by such
Purchaser or its affiliates in connection with the transactions contemplated by
this Agreement and no persons or entities are entitled to a fee or compensation
in respect thereof.

Section 4. CONDITIONS OF THE OBLIGATIONS OF THE PURCHASERS. The several
obligations of each Purchaser to purchase and pay for the Offered Securities on
the Closing Date will be subject to the satisfaction, or waiver by each
Purchaser, of each of the conditions below:

Date, of an officer of the Company in which such officer shall state that: the
representations and warranties of the Company in Section 2 of this Agreement are
correct; the Company has complied with all

<PAGE>

agreements and satisfied all conditions on its part to be performed or satisfied
hereunder at or prior to the Closing Date; and there has been no material and
adverse change in the business of the Company since the date of this Agreement.

     4.5 The business, assets, financial condition and operations of the Company
shall be substantially as represented to the Purchasers and no change shall have
occurred that, in the reasonable good faith judgment of the Purchasers, is or
could have a Material Adverse Effect, provided, however, that no change
constituting or related to (i) the economy or financial markets of the United
States of America or any other region, (ii) any change, effect or development
that is primarily caused by conditions generally effecting the industry in which
the Company conducts its business, (iii) any change that is primarily caused by
the announcement or pendency of this Agreement or the transactions contemplated
hereby or (iv) any generally applicable change in law, rule or regulation, shall
be deemed to be or have a Material Adverse Effect for the purposes of this
Section.

     4.6 Satisfactory completion of legal due diligence by the Purchasers.

     4.7 The Company and Meritech Capital Partners II L.P. ("Meritech") shall
have entered into an agreement providing for Board of Directors observing rights
for Meritech, in the form attached hereto as Exhibit B for so long as 50% of the
Offered Securities purchased by Meritech and its affiliates pursuant hereto
remain outstanding.

Section 5. CONDITIONS OF THE OBLIGATIONS OF THE COMPANY. The obligations of the
Company to sell the Offered Securities on the Closing Date to a Purchaser will
be subject to the satisfaction, or waiver by the Company, of each of the
conditions below:

     5.1 The representations and warranties of such Purchaser herein must be
correct and complete on the Closing Date and such Purchaser must have performed
all of its obligations hereunder required to be performed prior to the Closing
Date.

     5.2 Satisfaction of any notice period required by NASDAQ, and receipt of
any required clearances from NASDAQ.

     5.3 The holders of a majority of the outstanding shares of the Company's
Series A Preferred Stock shall have approved the authorization and issuance of
the Series B Preferred Stock.

Section 6. REGISTRATION OF THE REGISTRABLE SECURITIES; COMPLIANCE WITH THE
SECURITIES ACT.

     6.1 Registration Procedures. The Company is obligated to do the following:

          (a) On the date that is 17 months after the Closing Date, subject to
delivery by the Purchasers of information statements reasonably satisfactory to
the Company regarding the Purchasers' addresses and holdings of capital stock of
the Company, the Company shall prepare and file with the SEC one or more
registration statements in order to register with the SEC the resale by the
Purchasers, from time to time, of the Conversion Shares (which, along with only
Common Stock issued as (or issuable upon the conversion of exercise of any
warrant, right or

<PAGE>

other security that is issued as) a dividend or other distribution with respect
to, or in exchange for or in replacement of, the Offered Securities or the
Conversion Shares, are sometimes referred to herein as the "Registrable
Securities") through NASDAQ or the facilities of any national securities
exchange on which the Company's Common Stock is then traded, or in privately
negotiated transactions. The Company shall use its best efforts to cause such
registration statement to be declared effective as soon thereafter as reasonably
possible. The Company shall promptly notify the Purchasers of the effectiveness
of such registration statement.

          (b) The Company shall prepare and file with the SEC (i) such
amendments and supplements to any registration statement and the prospectus used
in connection therewith, and (ii) such other filings required by the SEC, in
each case as may be necessary to keep the registration statement continuously
effective and not misleading until the earlier of (A) the date that the
Purchasers have completed the distribution related to the Registrable
Securities, or (B) such time that all Registrable Securities then held by the
Purchasers can be sold within a given three (3) month period without compliance
with the registration requirements of the Securities Act pursuant to Rule 144
under the Securities Act; provided, however, that at any time, upon written
notice to the Purchasers and for a period not to exceed fifteen (15) days
thereafter (the "Suspension Period"), the Company may delay the filing or
effectiveness of any registration statement or suspend the use or effectiveness
of any registration statement (and the Purchasers hereby agree not to offer or
sell any Registrable Securities pursuant to such registration statement during
the Suspension Period) if the Company reasonably believes that the Company may,
in the absence of such delay or suspension hereunder, be required under state or
federal securities laws to disclose any corporate development the disclosure of
which could reasonably be expected to have an adverse effect upon the Company,
its stockholders, a potentially significant transaction or event involving the
Company, or any negotiations, discussions, or proposals directly relating
thereto. The Company may extend the Suspension Period for an additional
consecutive fifteen (15) days upon written notice to the Purchasers. The Company
agrees to use its commercially reasonable best efforts to insure that the
Suspension Period is kept to a minimum number of days. If so directed by the
Company, the Purchasers shall use their best efforts to deliver to the Company
(at the Company's expense) all copies, other than permanent file copies then in
the Purchasers' possession, of the prospectus relating to such Registrable
Securities current at the time of receipt of such notice.

          (c) Furnish to the Purchasers such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them, unless
the Company is already subject to service in such jurisdiction and except as
required by the Securities Act.

          (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Purchasers;
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

          (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing

<PAGE>

underwriter(s) of such offering. Each Purchaser participating in such
underwriting shall also enter into and perform its obligations under such an
agreement.

          (f) Notify each Purchaser whose Registrable Securities are covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing. The Company shall promptly amend or supplement such prospectus in
order to cause such prospectus not to include any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in the light of the circumstances
then existing.

          (g) Furnish, on the date that such Registrable Securities are
delivered to the underwriters for sale, if such securities are being sold
through underwriters, (i) an opinion, dated as of such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and (ii) a letter, dated as of
such date, from the independent certified public accountants of the Company, in
form and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering addressed to the
underwriters.

          (h) Cause all such Registrable Securities registered pursuant
hereunder to be listed on NASDAQ and each other securities exchange on which
similar securities issued by the Company are then listed.

     6.2 Transfer of Securities After Registration. Each Purchaser, severally
and not jointly, agrees that it will not effect any disposition of the
Registrable Securities that would constitute a sale within the meaning of the
Securities Act, unless:

          (a) pursuant to a registration statement then in effect covering such
disposition, if such disposition is made in accordance with such; or

          (b) the Purchaser shall have notified the Company of the proposed
disposition and shall have furnished the Company with a reasonably detailed
statement of the circumstances surrounding the proposed disposition, and if
reasonably requested by the Company, the Purchaser shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, or
other evidence, reasonably satisfactory to the Company, that such disposition
will not require registration of such Registrable Securities under the
Securities Act. It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to and in compliance with Rule 144, and
will not require (i) that such holder furnish the Company with a reasonably
detailed statement of the circumstances of the proposed disposition or (ii) an
opinion of counsel except in unusual circumstances.

          (c) Notwithstanding the provisions of paragraphs (a) and (b) above, no
such registration statement or opinion of counsel shall be necessary for a
transfer by a Purchaser

<PAGE>

(A) that is a partnership to its partners or former partners in accordance with
partnership interests, (B) that is a limited liability company to its members or
former members in accordance with their interest in the limited liability
company, (C) that is a corporation to its majority owned subsidiaries or
affiliates or (D) that is an individual or a trustee of a trust to the
Purchaser's family members, any trust for the benefit of such Purchaser or his
or her family members, or an entity whose equity owners consist solely of the
Purchaser and his or her family members; provided that in each case the
transferee will be subject to the terms of this Agreement to the same extent as
if such transferee were an original Purchaser hereunder.

     6.3 Legends. Each certificate representing Registrable Securities shall
(unless otherwise permitted by the provisions of the Agreement) be stamped or
otherwise imprinted with a legend substantially similar to the following (in
addition to any legend required under applicable state securities laws or as
provided elsewhere in this Agreement):

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE
     OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
     UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL OR BASED ON
     OTHER WRITTEN EVIDENCE IN THE FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER
     OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION
     IS IN COMPLIANCE THEREWITH.

     6.4 Expenses of Registration. Except as specifically provided herein, all
expenses incurred by the Company in complying with Section 6 hereof, including,
all registration and filing fees, printing expenses, fees and disbursements of
counsel for the Company, reasonable fees and expenses of one counsel to the
Purchasers, blue sky fees and expenses, reasonable fees and disbursements of one
counsel for the Purchasers, fees and the expense of any special audits incident
to or required by any such registration (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company) (collectively, the "Registration Expenses") shall be borne by the
Company. All underwriting discounts and selling commissions applicable to a sale
incurred in connection with any registrations hereunder shall be borne by the
holders of the securities so registered pro rata on the basis of the number of
shares so sold.

     6.5 Delay of Registration; Furnishing Information.

          (a) The Purchasers shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them and the intended
method of disposition of such securities as shall be required to effect the
registration of their Registrable Securities. Furthermore, each Purchaser,
severally and not jointly, agrees to promptly notify the Company of any changes
in the information set forth in a registration statement regarding such
Purchaser or its plan of distribution set forth in such registration statement.

     6.6 Indemnification. In the event any Registrable Securities are included
in a registration statement under this Section 6.

<PAGE>

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Purchaser, the partners, officers and directors of each
Purchaser, any underwriter (as defined in the Securities Act) for such Purchaser
and each person, if any, who controls such Purchaser or underwriter within the
meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading, or (iii) any violation
or alleged violation by the Company of the Securities Act, the Exchange Act, any
state securities law or any rule or regulation promulgated under the Securities
Act, the Exchange Act or any state securities law in connection with the
offering covered by such registration statement; and the Company will pay as
incurred to each such Purchaser, partner, officer, director, underwriter or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 6.6 shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Company, which consent shall not be unreasonably withheld,
nor shall the Company be liable in any such case for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon
a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
such Purchaser, partner, officer, director, underwriter or controlling person of
such Purchaser.

          (b) To the extent permitted by law, each Purchaser will, if
Registrable Securities held by such Purchaser are included in the securities as
to which such registration qualifications or compliance is being effected,
indemnify and hold harmless the Company, each of its directors, its officers and
each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Purchaser selling securities under
such registration statement or any of such other Purchaser's partners, directors
or officers or any person who controls such Purchaser, against any losses,
claims, damages or liabilities (joint or several) to which the Company or any
such director, officer, controlling person, underwriter or other such Purchaser,
or partner, director, officer or controlling person of such other Purchaser may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are based upon any Violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by such Purchaser under an
instrument duly executed by such Purchaser and stated to be specifically for use
in connection with such registration; and each such Purchaser will pay as
incurred any legal or other expenses reasonably incurred by the Company or any
such director, officer, controlling person, underwriter or other person
registering shares under such registration, or partner, officer, director or
controlling person of such other person registering shares under such
registration in connection with investigating or defending any such loss, claim,
damage, liability or action if it is judicially determined that there was such a
Violation; provided, however, that the indemnity

<PAGE>

agreement contained in this Section 6.6 shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Purchaser, which consent shall
not be unreasonably withheld; provided further, that in no event shall any
indemnity under this Section 6.6 exceed the net proceeds from the offering
received by such Purchaser.

          (c) Promptly after receipt by an indemnified party under this Section
6.6 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 6.6, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 6.6, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 6.6.

          (d) If the indemnification provided for in this Section 6.6 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the Violation(s) that resulted in such loss, claim, damage or
liability, as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and of the indemnified party shall be determined
by a court of law by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission to state a material
fact relates to information supplied by the indemnifying party or by the
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, that in no event shall any contribution by a Purchaser hereunder
exceed the net proceeds from the offering received by such Purchaser.

          (e) The obligations of the Company and the Purchasers under this
Section 6.6 shall survive completion of any offering of Registrable Securities
in a registration statement and the termination of this Agreement. No
indemnifying party, in the defense of any such claim or litigation, shall,
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation.

<PAGE>

     6.7 Agreement to Furnish Information. In connection with a registration in
which such Purchaser is participating, each Purchaser agrees to execute and
deliver such other agreements as may be reasonably requested by the Company or
the underwriter. In addition, if requested by the Company or the representative
of the underwriters of Common Stock (or other securities) of the Company, each
Purchaser shall provide, within ten (10) days of such request, such information
related to such Purchaser as may be required by the Company or such
representative in connection with the completion of any public offering of the
Company's securities pursuant to a registration statement filed under the
Securities Act.

     6.8 Rule 144 Reporting. With a view to making available to the Purchasers
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees to use its best efforts to:

          (a) Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act;

          (b) File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act; and

          (c) So long as a Purchaser owns any Registrable Securities, furnish to
such Purchaser forthwith upon request: a written statement by the Company as to
its compliance with the reporting requirements of said Rule 144 of the
Securities Act, and of the Exchange Act (at any time after it has become subject
to such reporting requirements); a copy of the most recent annual or quarterly
report of the Company; and such other reports and documents as a Purchaser may
reasonably request in availing itself of any rule or regulation of the SEC
allowing it to sell any such securities without registration.

     6.9 S-3 Eligibility. The Company will use its best efforts to meet the
requirements for the use of Form S-3 for registration of the resale by the
Purchasers of the Registrable Securities. The Company will use its best efforts
to file all reports required to be filed by the Company with the SEC in a timely
manner and take all other necessary action so as to maintain such eligibility
for the use of Form S-3.

Section 7. COVENANTS OF THE COMPANY.

     7.1 Due Diligence. The Company hereby undertakes to provide all information
and to make its employees available to the extent reasonably requested by the
Purchasers and their respective counsel in the course of performing their due
diligence investigation of the Company prior to the Closing Date.

Section 8. COVENANTS OF THE PURCHASERS.

     8.1 Confidentiality of Records. Each Purchaser agrees to use, and to use
its best efforts to insure that it and its authorized representatives use, the
same degree of care as such person uses to protect its own confidential
information to keep confidential any information furnished to it which the
Company identifies as being confidential or proprietary (so long as such
information has not been publicly disclosed by the Company or otherwise
generally known by

<PAGE>

such Purchaser or transferee), except that such person may disclose such
proprietary or confidential information to any partner, subsidiary or parent of
such person for the purpose of evaluating its investment in the Company as long
as such partner, subsidiary or parent is advised of the confidentiality
provisions of this Section 8.1. Notwithstanding the above, a Purchaser shall not
be in violation of this Section 8.1 with regard to a disclosure that was in
response to a valid order by a court or other governmental body or as required
by law or regulation, provided that such Purchaser provides the Company with
prior written notice of such disclosure in order to permit the Company to seek
confidential treatment or other appropriate remedy of such confidential
information; provided that, in the event that such confidential treatment or
other remedy is not requested or obtained, the Purchaser shall furnish only that
part of the confidential information that is legally required and shall exercise
its reasonable best efforts to ensure that the confidential information so
obtained is accorded treatment as confidential property.

     8.2 Prohibition on Use of Insider Information. Each Purchaser understands
that federal and state securities laws prohibit trading in the Company's
securities while such Purchaser is in the possession of "material nonpublic
information" concerning the Company and/or its affiliates. Each Purchaser
represents that it has been advised by its counsel of such laws and the
consequences of breaking such laws. Each Purchaser, and any transferee of
Registrable Securities, covenants not to enter into any transactions that would
violate applicable securities laws.

     8.3 Lock-up Period. Each of the Purchasers, severally and not jointly,
hereby agrees that from the date hereof and until 30 months after the Closing
Date (the "Lock-Up Expiration Date"), such Purchaser will not offer, sell,
contract to sell, pledge or otherwise dispose of, directly or indirectly, any
shares of the Company's Common Stock or securities convertible into or
exchangeable or exercisable for any shares of Common Stock (collectively, the
"Securities"), enter into a transaction which would have the same effect, or
enter into any swap, hedge or other arrangement that transfers, in whole or in
part, any of the economic consequences of ownership of the Securities, whether
any such aforementioned transaction is to be settled by delivery of the
Securities or other securities, in cash or otherwise, or publicly disclose the
intention to make any such offer, sale, pledge or disposition, or to enter into
any such transaction, swap, hedge or other arrangement, without, in each case,
the prior written consent of the Company. The foregoing sentence (x) shall not
apply to transactions relating to Securities acquired (i) by the Purchasers
prior to the execution of this Agreement or (ii) by the Purchasers in the open
market after the date of this Agreement, (y) shall expire, for each Purchaser,
with respect to 20% of the total number of Offered Securities purchased by such
Purchaser, on each of the 18 month anniversary of the Closing Date, the 21 month
anniversary of the Closing Date, the 24 month anniversary of the Closing Date
and the 27 month anniversary of the Closing Date, and (z) shall expire, for each
Purchaser, in its entirety upon the occurrence of any event deemed a Liquidation
(as such term in defined in the Certificate of Designations). In furtherance of
the foregoing, each of the Purchasers, severally and not jointly, agrees that
the Company and its transfer agent and registrar are hereby authorized to
decline to make any transfer of shares of Securities if such transfer would
constitute a violation or breach of the terms of this Section.

Section 9. EXEMPTION FROM REGISTRATION; LEGEND. The Offered Securities and the
Conversion Shares will be issued under an exemption or exemptions from
registration under the Securities Act, and are also subject to certain rights
and obligations set forth herein.

California, and each party consents to the exclusive jurisdiction of such courts
(or any appellate court therefrom) over any such dispute. Each party further
consents to personal jurisdiction in the courts mentioned in the prior sentence.

               CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS
                                       of

                            WIRELESS FACILITIES, INC.

     I, Masood K. Tayebi, Chief Executive Officer of WIRELESS FACILITIES, INC.,
a corporation organized and existing under the laws of the State of Delaware
(the "Corporation" or the "Company")), in accordance with the provisions of
Section 151 of the Delaware General Corporation Law, DO HEREBY CERTIFY:

     FIRST: That pursuant to the authority conferred upon the Board of Directors
of the Corporation (the "Board of Directors") by the Certificate of
Incorporation of the Corporation and by Section 151(g) of the Delaware General
Corporation Law, on May 16, 2002, the Board of Directors adopted the following
resolution, creating a series of shares of convertible preferred stock, Series
B, designated as "Series B Preferred Stock":

     "RESOLVED, that pursuant to the authority vested in the Board of Directors
     (the "Board of Directors") of WIRELESS FACILITIES, INC., a corporation
     organized and existing under the laws of the State of Delaware (the
     "Corporation"), by the Certificate of Incorporation of the Corporation (the
     "Certificate of Incorporation"), the Board of Directors does hereby provide
     for the authorization and issuance of a series of convertible preferred
     stock, Series B, par value U.S.$0.001 per share, of the Corporation, to be
     designated "Series B Preferred Stock," initially consisting of 90,000
     shares, and to the extent that the designations, powers, preferences, and
     relative participating, optional, or other special rights, and the
     qualifications, limitations, and restrictions of the Series B Preferred
     Stock are not stated and expressed in the Certificate of Incorporation, the
     Board of Directors does hereby fix and herein state and express such
     designations, powers, preferences, and relative participating, optional, or
     other special rights, and the qualifications, limitations, and restrictions
     thereof, as follows:

1.   Designation and Rank.

     (a) Ninety thousand (90,000) shares of the preferred stock of the
Corporation, par value $0.001 per share, shall be designated and known as the
"Series B Preferred Stock."

     (b) The Series B Preferred Stock shall rank senior and prior to the common
stock, par value U.S.$0.001 per share, of the Corporation (the "Common Stock"),
and all other classes or series of the capital stock (other than preferred
stock) of the Corporation (now or hereafter authorized or issued), with respect
to the payment of any dividends, the conversion rights set forth herein and any
payment upon liquidation or redemption. The Series B Preferred Stock shall rank
on par with the Series A Preferred Stock of the Corporation with respect to the
payment of any dividends, the conversion rights set forth herein and any payment
upon liquidation or redemption. The Corporation may not issue any additional
classes or series of preferred stock with liquidation, redemption or conversion
rights or right of payment of any kind that is senior to the Series B Preferred
Stock, except pursuant to Section 12.

                                       1.

<PAGE>

2.   Dividend Rights.

     From and after the date hereof, when and if the Board of Directors declares
a dividend or distribution payable with respect to the then-outstanding shares
of Common Stock (other than in additional shares of Common Stock or Common Stock
Equivalents (as defined in Section 4(e)(i) below), the holders of the Series B
Preferred Stock shall be entitled to the amount of dividends per share in the
same form as such Common Stock dividends that would be payable on the largest
number of whole shares of Common Stock into which a holder's aggregate shares of
Series B Preferred Stock could then be converted pursuant to Section 4 hereof
(such number to be determined as of the record date for the determination of
holders of Common Stock entitled to receive such dividend).

3.   Liquidation Rights.

     (a) Liquidation Events. The occurrence of any of the following events shall
be deemed a "Liquidation": (i) any liquidation, dissolution, or winding-up of
the affairs of the Corporation; (ii) any transaction or series of related
transactions in which securities of the Corporation representing 50% or more of
the combined voting power of the Corporation's then outstanding voting
securities are acquired by a person, entity or group of related persons or
entities, excluding any consolidation or merger effected exclusively to change
the domicile of the Corporation; (iii) any consolidation, merger or
reorganization of the Corporation with or into any other corporation or other
entity or person pursuant to which the holders of the Corporation's outstanding
securities receive, pursuant to such transaction, securities in the surviving
entity that represent less than 50% of the voting power of such surviving
entity; or (iv) any sale, lease, exclusive license or other disposition of all
or substantially all of the assets of the Corporation.

     (b) Liquidation Preference.

          (i) In the event of any Liquidation, whether voluntary or involuntary,
before any payment of cash or distribution of other property shall be made to
the holders of Common Stock, or any other class or series of stock subordinate
in liquidation preference to the Series B Preferred Stock, the holders of the
Series B Preferred Stock shall be entitled to receive out of the assets of the
Corporation legally available for distribution to its stockholders, on behalf of
each share of Series B Preferred Stock held by such holder, U.S.$500.00 (the
"Original Issue Price") (as appropriately adjusted for any combinations,
divisions, or similar recapitalizations affecting the Series B Preferred Stock
after issuance) and all accumulated or accrued and unpaid dividends thereon
(collectively, the "Series B Liquidation Preference").

          (ii) If, upon any Liquidation, the assets of the Corporation available
for distribution to its stockholders are insufficient to pay the holders of the
Series B Preferred Stock the full amounts to which they are entitled pursuant to
clause (b)(i) above, the holders of the Series B Preferred Stock shall share pro
rata in any distribution of assets in proportion to the respective amounts which
would be payable to the holders of the Series B Preferred Stock and any other
class or series of capital stock of the Corporation ranking on par with the
Series B Preferred Stock in respect of the shares held by them if all amounts
payable to them in respect of such were paid in full pursuant to clause (b)(i)
above.

                                       2.

<PAGE>

          (iii) After the distributions described in clause (b)(i) or (b)(ii)
above have been paid, subject to the rights of any other class or series of
capital stock of the Corporation that may from time to time come into existence,
the remaining assets of the Corporation available for distribution to
stockholders shall be distributed among the holders of Common Stock pro rata
based on the number of shares of Common Stock held by each.

     (c) Non-Cash Distributions. If any distribution to be made pursuant to this
Section 3 is to be paid other than in cash or Common Stock or Common Stock
Equivalents, the value of such distribution will be deemed its fair market value
as determined in good faith by the Board of Directors. Any securities shall be
valued as follows:

          (i) Securities not subject to investment letter or other similar
restrictions on free marketability covered by clause (ii) below:

               (1) if traded on a securities exchange or through the Nasdaq
National Market, the value shall be deemed to be the average of the closing
prices of the securities on such quotation system over the thirty (30) trading
day period ending three (3) trading days prior to the occurrence of the
Liquidation;

               (2) if actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid or sale prices (whichever is
applicable) over the thirty (30) trading day period ending three (3) trading
days prior to the occurrence of the Liquidation; and

               (3) if there is no active public market, the value shall be the
fair market value thereof, as determined by the Board of Directors.

          (ii) The method of valuation of securities subject to investment
letter or other restrictions on free marketability (other than restrictions
arising solely by virtue of a stockholder's status as an affiliate or former
affiliate) shall be to effectuate an appropriate discount from the market value,
as determined by clause (i)(1), (2) or (3) of this Section 3(c), so as to
reflect the approximate fair market value thereof, as determined by the Board of
Directors.

          (iii) The holders of at least a majority of the outstanding Series B
Preferred Stock shall have the right to challenge any determination by the Board
of Directors of fair market value pursuant to this Section 3(c), in which case
the determination of fair market value shall be made by an independent appraiser
selected jointly by the Board of Directors and the challenging parties, the cost
of such appraisal to be borne equally by the Corporation and the challenging
parties.

4.   Conversion Rights.

     The holders of the Series B Preferred Stock shall have conversion rights as
follows (the "Conversion Right"):

     (a) Conversion Price. The "Conversion Price" shall, initially, be U.S.$5.00
per share and shall be subject to adjustment as set forth below in Sections 4(e)
and 4(f).

                                       3.

<PAGE>

     (b) Automatic Conversion. If the closing price for the shares of the
Corporation's Common Stock (trading on a securities exchange or through Nasdaq
National Market or other national exchange or market) exceeds $11.00 per share
(as adjusted for events described in Section 4(e)(ii) and 4(e)(iii) below) for
any thirty consecutive trading day period that begins after February 28, 2005,
then, upon such occurrence, each share of Series B Preferred Stock shall be
automatically converted into such number of fully paid and non-assessable shares
of Common Stock as is determined by dividing (x) the Original Issue Price of
such share of Series B Preferred Stock (including any accumulated or accrued but
unpaid dividends thereon) by (y) the Conversion Price. The date of such
conversion is herein referred to as the "Conversion Date."

     (c) Optional Conversion. The holders of the Series B Preferred Stock shall
have the right, at any time, to convert the shares of Series B Preferred Stock
held by such holder into that number of shares of Common Stock into which such
shares are convertible pursuant to Section 4(b) ("Optional Conversion"). In the
event of any Optional Conversion, the date of such conversion shall be referred
to as the "Optional Conversion Date."

     (d) Mechanics of Conversion. On the Conversion Date or Optional Conversion
Date, as the case may be, (x) each holder shall tender such holder's shares of
Series B Preferred Stock to the Corporation for cancellation, free and clear of
encumbrances of any type or nature, and (y) the Corporation shall cause to be
delivered to such holder a number of shares of Common Stock as calculated
pursuant to Section 4(b) above, free and clear of encumbrances of any type or
nature. Each holder and the Corporation shall take all other necessary or
appropriate actions in connection with or to effect such closing.

     (e) Certain Adjustments. To the extent that the holders of Series B
Preferred Stock do not participate fully with other stockholders of the
Corporation with respect to dividends paid pursuant to Section 2 hereof, the
following adjustments shall be made to the Conversion Price:

          (i) Adjustment for Common Stock Dividends and Distributions. If, at
any time after the original issue date of the Series B Preferred Stock (the
"Original Issue Date"), the Corporation makes, or fixes a record date for the
determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in additional shares of Common Stock or Common Stock
Equivalents, in each such event the Conversion Price that is then in effect
shall be decreased as of the time of such issuance or, in the event such record
date is fixed, as of the close of business on such record date, by multiplying
the Conversion Price then in effect by a fraction (i) the numerator of which is
the total number of shares of Common Stock and Common Stock Equivalents issued
and outstanding immediately prior to the time of such issuance or the close of
business on such record date, and (ii) the denominator of which is the total
number of shares of Common Stock and Common Stock Equivalents issued and
outstanding immediately prior to the time of such issuance or the close of
business on such record date plus the number of shares of Common Stock or Common
Stock Equivalents issuable in payment of such dividend or distribution;
provided, however, that if such record date is fixed and such dividend is not
fully paid or if such distribution is not fully made on the date fixed therefor,
the Conversion Price shall be recomputed accordingly as of the close of business
on such record date and thereafter the Conversion Price shall be adjusted
pursuant to this Section 4(e)(i) to reflect the actual payment of such dividend
or distribution.

                                       4.

<PAGE>

               A "Common Stock Equivalent" shall mean each share of Common Stock
into which securities or property or rights are convertible, exchangeable or
exercisable for or into shares of Common Stock, or otherwise entitle the holder
thereof to receive directly or indirectly, any of the foregoing.

          (ii) Adjustments for Stock Splits, Stock Subdivisions and
Combinations. If, at any time after the Original Issue Date, the Corporation
subdivides or combines the Common Stock without making a corresponding
subdivision or combination of the Series B Preferred Stock, (A) in the case of a
subdivision (including a stock split), the Conversion Price in effect
immediately prior to such event shall be proportionately decreased and the
number of shares of Common Stock purchasable thereunder shall be proportionately
increased, and (B) in the case of a combination (including a reverse stock
split), the Conversion Price in effect immediately prior to such event shall be
proportionately increased and the number of shares of Common Stock purchasable
thereunder shall be proportionately decreased. Any adjustment under this Section
4(e)(ii) shall become effective at the close of business on the date the
subdivision or combination becomes effective.

          (iii) Adjustments for Reclassification, Reorganization and
Consolidation. In case of (A) any reclassification, reorganization, change or
conversion of securities of the class issuable upon conversion of the Series B
Preferred Stock (other than a change in par value, or from par value to no par
value) into other shares or securities of the Corporation, or (B) any merger or
consolidation of the Corporation with or into another entity (other than a
Liquidation or a merger or consolidation with another entity in which the
Corporation is the acquiring and the surviving entity and that does not result
in any reclassification or change of outstanding securities issuable upon
conversion of the Series B Preferred Stock) each holder of shares of Series B
Preferred Stock shall have the right to receive, in lieu of the shares of Common
Stock otherwise issuable upon the conversion of its shares of Series B Preferred
Stock (and accumulated or accrued and unpaid dividends then-outstanding
thereunder) in accordance with Section 4(b), the kind and amount of shares of
stock and other securities, money and property receivable upon such
reclassification, reorganization, change, merger or consolidation upon
conversion by a holder of the maximum number of shares of Common Stock into
which such shares of Series B Preferred Stock could have been converted
immediately prior to such reclassification, reorganization, change, merger or
consolidation, all subject to further adjustment as provided herein or with
respect to such other securities or property by the terms thereof. The
provisions of this clause (iii) shall similarly attach to successive
reclassifications, reorganizations, changes, mergers and consolidations.

     (f) Antidilution Adjustments. To the extent that (i) the Corporation issues
after the Original Issue Date and before November 30, 2003, Additional Shares of
Common Stock (as defined below) (in one or more transactions, whether or not
related), (ii) each such issuance is at an Effective Price (as defined below)
per share less than Conversion Price then in effect and (iii) the aggregate
gross proceeds of such issuances exceed $15 million, then the Conversion Price
shall be adjusted to equal the lowest Effective Price received by the
Corporation pursuant to any such issuance. The previous sentence will apply to
any issuances of Additional Shares of Common Stock after the $15 million
threshold has been met (provided any such issuance is below the Conversion Price
then in effect) but will not apply to any issuance of Additional

                                       5.

<PAGE>

Shares of Common Stock occurring after November 30, 2003. Notwithstanding the
foregoing, the Conversion Price shall in no event be lower than U.S.$4.17.

          (i) For the purpose of making any adjustment required under Section
4(f), the consideration received by the Company for any issue or sale of
securities shall (A) to the extent it consists of cash, be computed at the net
amount of cash received by the Company after deduction of any underwriting or
similar commissions, compensation or concessions paid or allowed by the Company
in connection with such issue or sale but without deduction of any expenses
payable by the Company (except for purposes of determining if the $15 million
threshold referred to above has been met, in which case the consideration
received will be deemed to be the aggregate gross proceeds received by the
Company), (B) to the extent it consists of property other than cash, be computed
at the fair value of that property as determined in good faith by the Board of
Directors, and (C) if Additional Shares of Common Stock, Convertible Securities
(as defined below) or rights or options to purchase either Additional Shares of
Common Stock or Convertible Securities are issued or sold together with other
stock or securities or other assets of the Company for a consideration which
covers both, be computed as the portion of the consideration so received that
may be reasonably determined in good faith by the Board of Directors to be
allocable to such Additional Shares of Common Stock, Convertible Securities or
rights or options; provided, however, that the holders of at least a majority of
the outstanding Series B Preferred Stock shall have the right to challenge any
determination by the Board of Directors of fair market value pursuant to this
Section 4(f)(i), in which case the determination of fair market value shall be
made by an independent appraiser selected jointly by the Board of Directors and
the challenging parties, the cost of such appraisal to be borne equally by the
Corporation and the challenging parties.

          (ii) For the purpose of the adjustment required under this Section
4(f), if the Company issues or sells (A) stock or other securities convertible
into, Additional Shares of Common Stock (such convertible stock or securities
being herein referred to as "Convertible Securities") or (B) rights or options
for the purchase of Additional Shares of Common Stock or Convertible Securities
and if the Effective Price of such Additional Shares of Common Stock is less
than the Conversion Price, in each case the Company shall be deemed to have
issued at the time of the issuance of such rights or options or Convertible
Securities the maximum number of Additional Shares of Common Stock issuable upon
exercise or conversion thereof and to have received as consideration for the
issuance of such shares an amount equal to the total amount of the
consideration, if any, received by the Company for the issuance of such rights
or options or Convertible Securities, plus, in the case of such rights or
options, the minimum amounts of consideration, if any, payable to the Company
upon the exercise of such rights or options, plus, in the case of Convertible
Securities, the minimum amounts of consideration, if any, payable to the Company
(other than by cancellation of liabilities or obligations evidenced by such
Convertible Securities) upon the conversion thereof; provided that if in the
case of Convertible Securities the minimum amounts of such consideration cannot
be ascertained, but are a function of antidilution or similar protective
clauses, the Company shall be deemed to have received the minimum amounts of
consideration without reference to such clauses; provided further that if the
minimum amount of consideration payable to the Company upon the exercise or
conversion of rights, options or Convertible Securities is reduced over time or
on the occurrence or non-occurrence of specified events other than by reason of
antidilution adjustments, the Effective Price shall be recalculated using the
figure to which such minimum amount of consideration is

                                       6.

<PAGE>

reduced; provided further that if the minimum amount of consideration payable to
the Company upon the exercise or conversion of such rights, options or
Convertible Securities is subsequently increased, the Effective Price shall be
again recalculated using the increased minimum amount of consideration payable
to the Company upon the exercise or conversion of such rights, options or
Convertible Securities. No further adjustment of the Conversion Price, as
adjusted upon the issuance of such rights, options or Convertible Securities,
shall be made as a result of the actual issuance of Additional Shares of Common
Stock on the exercise of any such rights or options or the conversion of any
such Convertible Securities. If any such rights or options or the conversion
privilege represented by any such Convertible Securities shall expire without
having been exercised, the Conversion Price, as adjusted upon the issuance of
such rights, options or Convertible Securities, shall be readjusted to the
Conversion Price which would have been in effect had an adjustment been made on
the basis that the only Additional Shares of Common Stock so issued were the
Additional Shares of Common Stock, if any, actually issued or sold on the
exercise of such rights or options or rights of conversion of such Convertible
Securities, and such Additional Shares of Common Stock, if any, were issued or
sold for the consideration actually received by the Company upon such exercise,
plus the consideration, if any, actually received by the Company for the
granting of all such rights or options, whether or not exercised, plus the
consideration received for issuing or selling the Convertible Securities
actually converted, plus the consideration, if any, actually received by the
Company (other than by cancellation of liabilities or obligations evidenced by
such Convertible Securities) on the conversion of such Convertible Securities.

                    "Additional Shares of Common Stock" shall mean all shares of
Common Stock issued by the Company or deemed to be issued pursuant to this
Section 4(f), whether or not subsequently reacquired or retired by the Company
other than (A) shares of Common Stock and/or options, warrants or other Common
Stock purchase rights, and the Common Stock issued or issuable pursuant to such
options, warrants or other rights to employees, officers or directors of, or
consultants or advisors to the Company or any subsidiary pursuant to stock
purchase or stock option plans or other arrangements that are approved by the
Board; (B) shares of Common Stock issued or issuable pursuant to any equipment
loan or leasing arrangement, or debt financing from a bank or similar financial
institution; (C) shares of Common Stock issued or issuable in connection with
licensing transactions involving the Company and other entities, including (1)
joint ventures, manufacturing, marketing or distribution arrangements or (2)
technology transfer or development arrangements; provided that such transactions
in (1) and (2) and the issuance of shares therein has been approved by a
majority of the members of the Company's Board of Directors and the aggregate
number of shares so issued does not exceed four million (4,000,000)(as adjusted
for stock splits, stock dividends, stock combinations, recapitalizatons and the
like); and (D) any other issuances approved by the holders of a majority of the
Series B Preferred Stock then outstanding.

                    The "Effective Price" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Company under this Section 4(f), into the aggregate consideration received,
or deemed to have been received by the Company for such issue under this Section
4(f), for such Additional Shares of Common Stock.

                                       7.

5.   Other Distributions.

     In the event the Corporation provides the holders of its Common Stock with
consideration that is not otherwise addressed in Section 4 (including, without
limitation, declaring a distribution payable in securities, assets, cash or
evidences of indebtedness issued by other persons or the Corporation (excluding
cash dividends declared and paid by the Corporation out of retained earnings)),
then, in each such case, the holders of the Series B Preferred Stock shall be
entitled to a pro rata share of any such distribution as though such holders
were holders of the number of shares of Common Stock of the Corporation as
though the Series B Preferred Stock had been converted in whole as of the record
date fixed for the determination of the holders of Common Stock of the
Corporation entitled to receive such distribution.

6.   Recapitalizations.

     If at any time there occurs a recapitalization of the Common Stock (other
than a subdivision, combination, or merger or sale of assets provided for in
Section 4 hereof), the holders of the Series B Preferred Stock shall be entitled
to receive upon conversion of the Series B Preferred Stock the number of shares
of capital stock or other securities or property of the Corporation or otherwise
to which a holder of the Common Stock deliverable upon conversion would have
been entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of Section 4 hereof with
respect to the rights of the holders of the Series B Preferred Stock after the
recapitalization to the end that the provisions of Section 4 hereof (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of the Series B Preferred Stock) shall be applicable
after that event as nearly equivalent as may be practicable.

7.   No Impairment.

     The Corporation will not, by amendment of the Certificate of Incorporation
or through any reorganization, recapitalization, transfer of assets,
consolidation, merger, dissolution, issuance or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions hereof
and in the taking of all such action as may be necessary or appropriate in order
to protect the Conversion Right of the holders of the Series B Preferred Stock
against impairment.

8.   No Fractional Shares and Certificate as to Adjustments.

     (a) No fractional shares of Common Stock will be issued upon the conversion
of any share or shares of the Series B Preferred Stock. All shares of Common
Stock (including fractions thereof) issuable upon conversion of more than one
share of Series B Preferred Stock by a holder shall be aggregated for purposes
of determining whether the conversion would result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of a fraction of a share of Common Stock, the Corporation
shall, in lieu of issuing any fractional share, pay the holder otherwise
entitled to such fraction a sum in cash equal to such fraction multiplied by the
closing price of the Corporation's Common Stock on the Nasdaq National Market
(or any other national securities exchange on which the Common

                                       8.

<PAGE>

Stock is then traded) on the day immediately preceding the conversion. All
calculations under Section 4 hereof and this Section 8(a) shall be made to the
nearest cent or to the nearest share, as the case may be.

     (b) Upon the occurrence of each adjustment or readjustment of the
Conversion Price pursuant to Section 4 hereof, the Corporation, at its expense,
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and prepare and furnish to each holder of shares of Series B
Preferred Stock a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Series B Preferred Stock, use its reasonable best efforts to furnish or cause to
be furnished to such holder a like certificate setting forth (i) such adjustment
or readjustment, (ii) the Conversion Price at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of a share of Series B
Preferred Stock.

9.   Reservation of Stock Issuable Upon Conversion.

     The Corporation shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of the shares of the Series B Preferred Stock, such
number of its shares of Common Stock that shall from time to time be sufficient
to effect the conversion of all outstanding shares of the Series B Preferred
Stock; and if at any time the number of authorized but unissued shares of Common
Stock not otherwise reserved for issuance shall not be sufficient to effect the
conversion of all then outstanding shares of the Series B Preferred Stock, the
Corporation shall take such corporate action that may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes,
including, without limitation, engaging in best efforts to obtain the requisite
stockholder approval of any necessary amendment to its Certificate of
Incorporation.

10.  Notices.

     Any notice required by the provisions hereof to be given to the holders of
shares of Series B Preferred Stock shall be given in writing and shall be deemed
to have been given (i) in the case of personal or hand delivery, on the date of
such delivery, (ii) in the case of an internationally-recognized overnight
delivery courier, on the second business day after the date when sent, (iii) in
the case of mailing, on the fifth business day following that day on which the
piece of mail containing such communication is posted, and (iv) in the case of
facsimile transmission, the date of telephone confirmation of receipt.

11.  Voting Rights.

     Holders of Series B Preferred Stock shall be entitled to vote on all
matters submitted to a vote of the holders of the Corporation's Common Stock,
including with respect to the election of directors of the Corporation, on an as
if converted to Common Stock basis; provided, however, that the number of votes
to which the Series B Preferred Stock is entitled shall be based on a conversion
price of $5.00 per share, giving effect to any future adjustments pursuant to
Section

                                       9.

<PAGE>

4(e) above, but without giving any effect to any future adjustments pursuant to
Section 4(f) above.

12.  Protective Provisions.

Subject to the rights of any series of preferred stock that may from time to
time come into existence, so long as any shares of Series B Preferred Stock are
outstanding, the Corporation shall not without first obtaining the approval (by
vote or written consent, as provided by law) of the holders of at least a
majority of the then-outstanding shares of Series B Preferred Stock, voting
separately as a series:

     (a) amend its Certificate of Incorporation (including the filing of a
Certificate of Designations) so as to (i) increase the number of authorized
shares of the Corporation's preferred stock or (ii) affect adversely the shares
of Series B Preferred Stock or any holder thereof, including, without
limitation, by creating any additional series of preferred stock (or issuing
shares under any such series) that is senior or pari passu in liquidation
preference, redemption right, conversion rights or right of payment to the
Series B Preferred Stock;

     (b) after the date of this Certificate of Designation, create any new debt
instrument or create or increase any new or existing bank line (or similar
arrangement pursuant to which the Company is or becomes indebted), so that the
Company's total indebtedness pursuant to such instruments, lines or arrangements
exceeds $105,000,000 in the aggregate; or

     (c) change the rights of the holders of the Series B Preferred Stock in any
other respect;

provided, however, that the authorization and issuance of additional shares of
Common Stock, and creation of any series of preferred stock (or issuing shares
under any such series) that is junior in right of payment upon liquidation,
redemption, conversion and payment rights and otherwise to the Series B
Preferred Stock shall not be deemed to adversely affect the rights, preferences
or privileges of the Series B Preferred Stock or any holder thereof or change
the rights of the holders of the Series B Preferred Stock in any other respect.

     The Series B Preferred Stock shall have no preemptive rights pursuant
hereto.

13.  Legend.

     The Series B Preferred Stock and any underlying shares of Common Stock will
be issued under an exemption or exemptions from registration under the Act.
Accordingly, the certificates evidencing the Series B Preferred Stock and the
underlying Common Stock shall, upon issuance, contain a legend, substantially in
the form as follows:

     "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE U.S.
     SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE STATE
     SECURITIES LAWS AND NO INTEREST HEREIN MAY BE SOLD, TRANSFERRED OR
     OTHERWISE DISPOSED OF UNLESS (1) A REGISTRATION STATEMENT WITH RESPECT TO
     SUCH SECURITIES SHALL BE EFFECTIVE UNDER

                                       10.

<PAGE>

THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR (2) SUCH SECURITIES ARE
TRANSFERRED PURSUANT TO RULE 144 PROMULGATED UNDER THE ACT (OR ANY SUCCESSOR
RULE) OR (3) THE ISSUER OF THESE SECURITIES SHALL HAVE RECEIVED AN OPINION OF
COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE ISSUER
THAT NO VIOLATION OF THE ACT OR SIMILAR STATE SECURITIES LAWS WILL BE INVOLVED

Re:   Board Observation Rights

Ladies and Gentlemen:

In connection with the sale and issuance by Wireless Facilities, Inc. (the
"Company") of shares of its Series B Preferred Stock pursuant to the Preferred
Stock Purchase Agreement dated as of May 16, 2002 among the Company and each of
the purchasers listed on Schedule 1 thereto (the "Stock Purchase Agreement"),
the Company hereby agrees that a representative of Meritech Capital Partners II
L.P. ("Meritech"), which representative shall initially be Paul Madera, shall
have the right to attend all meetings of its Board Of Directors ("the Board")
(including telephonic and other electronic meetings to the extent that members
of the Board are attending such meetings in such manner) in a nonvoting,
observer capacity. The Company also agrees to provide such representative (in
advance, to the extent members of the Board receive such materials in advance)
copies of all notices, minutes, consents, and other materials that it provides
to members of the Board by reason of their membership; provided, however, that
the Company reserves the right to exclude in its sole discretion, such
representative from access to any material or meeting or portion thereof if the
Company, upon advice of counsel, in good faith believes that such exclusion is
reasonably necessary to preserve the attorney-client privilege. The Company
agrees to reimburse Meritech's representative for all reasonable expenses
incurred by such representative in connection with his or her attendance of the
meetings of the Board.

Meritech agrees, and any representative of Meritech will agree, to hold in
confidence and trust and to not use or disclose any confidential information
provided to or learned by it in connection with its rights under this letter.

The rights described herein shall terminate and be of no further force or effect
at such time as fifty percent (50%) of the Offered Securities (as defined in the
Stock Purchase Agreement) purchased by Meritech pursuant to the Stock Purchase
Agreement no longer remain outstanding (as adjusted for stock dividends,
combinations, splits, recapitalizations and the like). The confidentialityy
provisions hereof will survive such termination.

Very truly yours,

Wireless Facilities, Inc.

(d) in this Section, the Trust shall not issue additional Certificates or
additional Call Warrants or incur any indebtedness.

     (b) The Class A-1 Certificates have an initial aggregate certificate
principal balance (the "Certificate Principal Balance") of $25,000,000 and the
Class A-2 Certificates have an initial aggregate Certificate Principal Balance
of $1,210,000.

     (c) The holders of the Class A-1 Certificates will be entitled to receive
on each Distribution Date the interest, if any, received on the Underlying
Securities, to the extent necessary to pay interest at a rate of 8.125% per
annum on the outstanding Certificate Principal Balance of the Class A-1
Certificates. The Class A-2 Certificates will not bear interest. On the
Distribution Date occurring in December 2002, the Trustee will pay to the
Depositor the amount of interest accrued and paid on the Underlying Securities
from June 1, 2002, to but not including the Closing Date; provided, however,
that in the event an Optional Exchange shall occur prior to September 1, 2002,
a pro rata portion of such amount shall be paid to the Depositor on the
Optional Exchange Date, in accordance with the provisions of Section 7(c)(vii)
hereof. If Available Funds are insufficient to pay such amount, the Trustee
will pay the Depositor its pro rata share, based on the ratio the amount owed
to the Depositor bears to all amounts owed on the Certificates in respect of
accrued interest, of any proceeds from the recovery on the Underlying
Securities.

     (d) The Depositor may sell to the Trustee additional Underlying
Securities on any date hereafter upon at least 3 Business Days' notice to the
Trustee (or such shorter period as shall be mutually satisfactory to the
Depositor and the Trustee) and upon (i) satisfaction of the Rating Agency
Condition and (ii) delivery of an Opinion of Counsel to the effect that the
sale of such additional Underlying Securities will not cause the Trust to be
taxed as an association or publicly traded partnership taxable as a
corporation for federal income tax purposes. Each condition to be satisfied
with respect to a sale of Underlying Securities on or prior to the Closing
Date shall be satisfied with respect to a sale of additional Underlying
Securities no later than the date of sale thereof, each representation and
warranty set forth in the Standard Terms to be made on the Closing Date shall
be made on such date of sale, and from and after such date of sale, all
Underlying Securities held by the Trustee shall be held on the same terms and
conditions. Upon

                                      8
<PAGE>

such sale to the Trustee, the Trustee shall deposit such additional Underlying
Securities in the Certificate Account, and shall authenticate and deliver to
the Depositor, on its order, Class A-1 Certificates and Class A-2 Certificates
in the same proportion as the original Class A-1 Certificates and Class A-2
Certificates, with an aggregate Certificate Principal Balance equal to the
principal amount of such additional Underlying Securities, and the Call
Warrants related thereto as described herein. Any such additional Class A-1
Certificates and Class A-2 Certificates authenticated and delivered shall have
the same terms and rank pari passu with the corresponding classes of
Certificates previously issued in accordance with this Series Supplement.

     (e) No Class A-2 Certificate may be offered, resold, assigned or
otherwise transferred (including by pledge or hypothecation) at any time prior
to (x) the date which is two years or such shorter period of time as permitted
by Rule 144(k) under the Securities Act, after the later of the original issue
date of such Class A-2 Certificates and the last date on which the Depositor
or any "affiliate" (as defined in Rule 144 under the Securities Act) of the
Depositor was the owner of such Class A-2 Certificates (or any predecessor
thereto), or (y) such later date, if any, as may be required by a change in
applicable securities laws (the "Resale Restriction Termination Date") unless
such offer, resale, assignment or transfer is (i) to the Trust, (ii) pursuant
to an effective registration statement under the Securities Act, (iii) to a
qualified institutional buyer (a "QIB"), as such term is defined in Rule 144A
promulgated under the Securities Act ("Rule 144A"), in accordance with Rule
144A or (iv) pursuant to another available exemption from registration
provided under the Securities Act, and, in each of cases (i) through (iv), in
accordance with any applicable securities laws of any state of the United
States and other jurisdictions. Prior to any offer, resale, assignment or
transfer of any Class A-2 Certificates in the manner described in clause (iii)
above, the prospective transferee and the prospective transferor shall be
required to deliver to the Trustee an executed copy of an Investment Letter
with respect to the Class A-2 Certificates to be transferred substantially in
the form of Exhibit C hereto. Prior to any offer, resale, assignment or
transfer of any Class A-2 Certificates in the manner described in clause (iv)
above, the prospective transferee and the prospective transferor shall be
required to deliver to the Trustee documentation certifying that the offer,
resale, assignment or transfer complies with the provisions of said clause
(iv). In addition to the foregoing, each prospective transferee of any Class
A-2 Certificates in the manner contemplated by clause (iii) above shall
acknowledge, represent and agree as follows:

     (1)  The transferee (x) is a QIB, (y) is aware that the sale to it is
          being made in reliance on Rule 144A and (z) is acquiring such Class
          A-2 Certificates or Call Warrants, as applicable, for its own
          account or for the account of a QIB.

     (2)  The transferee understands that the Class A-2 Certificates or Call
          Warrants, as applicable, are being offered in a transaction not
          involving any public offering in the United States within the
          meaning of the Securities Act, and that the Class A-2 Certificates
          or Call Warrants, as applicable, have not been and will not be
          registered under the Securities Act.

     (3)  The transferee agrees that (A) if in the future it decides to offer,
          resell, pledge or otherwise transfer the Class A-2 Certificates or
          Call Warrants, as applicable, prior to the Resale Restriction
          Termination Date, such Class A-2 Certificates or Call

                                      9
<PAGE>

          Warrants, as applicable, shall only be offered, resold, assigned or
          otherwise transferred (i) to the Trust, (ii) pursuant to an
          effective registration statement under the Securities Act, (iii) to
          a QIB, in accordance with Rule 144A or (iv) pursuant to another
          available exemption from registration provided under the Securities
          Act, and, in each of cases (i) through (iv), in accordance with any
          applicable securities laws of any state of the United States and
          other jurisdictions and (B) the transferee will, and each subsequent
          holder is required to, notify any subsequent purchaser of such Class
          A-2 Certificates or Call Warrants, as applicable, from it of the
          resale restrictions referred to in clause (A) above.

     (f) The Class A-2 Certificates will, unless otherwise agreed by the
Depositor and the Trustee, bear a legend substantially to the following
effect:

          "THIS CLASS A-2 CERTIFICATE (OR ITS PREDECESSOR) HAS NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT
          BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A
          REGISTRATION UNDER SUCH ACT IS IN EFFECT OR PURSUANT TO AN EXEMPTION
          THEREFROM UNDER SUCH ACT. THE CLASS A-2 CERTIFICATE REPRESENTED
          HEREBY MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF THE
          SERIES SUPPLEMENT.

          EACH PURCHASER OF THIS CLASS A-2 CERTIFICATE IS HEREBY NOTIFIED THAT
          THE SELLER OF THIS CLASS A-2 CERTIFICATE MAY BE RELYING ON THE
          EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT
          PROVIDED BY RULE 144A THEREUNDER."

     Section 4. Trust Certificates. The Trustee hereby acknowledges receipt,
on or prior to the Closing Date, of:

     (a) the Underlying Securities set forth on Schedule I hereto; and

     (b) all documents required to be delivered to the Trustee pursuant to
Section 2.01 of the Standard Terms.

     Section 5. Distributions.

     (a) Except as otherwise provided in Section 3(c), 5(b), 5(c) and 5(h) on
each applicable Distribution Date (or such later date as specified in Section
9(f)), the Trustee shall apply Available Funds in the Certificate Account as
follows:

          (i) The Trustee will pay the interest portion of Available Funds
     (subject to Section 5(c) below):

                                      10
<PAGE>

               (1) first, to the Trustee, as reimbursement for any
          Extraordinary Trust Expenses incurred by the Trustee in accordance
          with Section 6(b) below and approved by 100% of the
          Certificateholders; and

               (2) second, to the holders of the Class A-1 Certificates, as
          interest at the rate of 8.125% per annum on the outstanding
          Certificate Principal Balance of the Class A-1 Certificates.

          (ii) the Trustee will pay the principal portion of Available Funds:

               (1) first, to the Trustee, as reimbursement for any remaining
          Extraordinary Trust Expenses incurred by the Trustee in accordance
          with Section 6(b) below and approved by 100% of the
          Certificateholders; and

               (2) second, to the holders of the Class A-1 Certificates and
          the Class A-2 Certificates, the remaining available principal
          portion of Available Funds (in an aggregate amount not to exceed the
          outstanding Certificate Principal Balance of the Class A-1
          Certificates and Class A-2 Certificates) pro rata in the proportion
          that the outstanding Certificate Principal Balance of the Class A-1
          Certificates bears to the outstanding Certificate Principal Balance
          of the Class A-2 Certificates.

          (iii) any Available Funds remaining in the Certificate Account after
     the payments set forth in clauses 5(a)(i) and 5(a)(ii) above shall be
     paid to the Trustee as reasonable compensation for services rendered to
     the Depositor, up to $1,000.

          (iv) the Trustee will pay any Available Funds remaining in the
     Certificate Account after the distributions in clauses 5(a)(i) through
     5(a)(iii) above to the holders of the Class A-1 Certificates and Class
     A-2 Certificates pro rata in proportion to their original Certificate
     Principal Balances.

Any portion of the Available Funds (i) that does not constitute principal of,
or interest on, the Underlying Securities, (ii) that is not received in
connection with a redemption, prepayment or liquidation of the Underlying
Securities and (iii) for which allocation by the Trustee is not otherwise
contemplated by this Series Supplement, shall be remitted by the Trustee to
the Depositor.

     (b) Notwithstanding any other provision hereof (other than Section 3(c))
if the Underlying Securities are prepaid or liquidated in whole or in part for
any reason other than if the Underlying Securities Guarantor discontinues
filing the periodic reports required under the Exchange Act or at their
maturity, the Trustee shall apply Available Funds in the manner described in
Section 5(f) in the following order of priority:

          (i) first, to the Trustee, as reimbursement for any Extraordinary
     Trust Expenses incurred by the Trustee in accordance with Section 6(b)
     below and approved by 100% of the Certificateholders;

                                      11
<PAGE>

          (ii) second, to the holders of the Class A-1 Certificates, an amount
     equal to any accrued and unpaid interest thereon;

          (iii) third, to the holders of the Class A-1 Certificates and Class
     A-2 Certificates, pro rata in the proportion that the outstanding
     Certificate Principal Balance of the Class A-1 Certificates bears to the
     outstanding Certificate Principal Balance of the Class A-2 Certificates;

          (iv) fourth, to the Trustee, as reasonable compensation for services
     rendered to the Depositor, any remainder up to $1,000; and

          (v) fifth, to the holders of the Class A-1 Certificates and Class
     A-2 Certificates, any amount remaining after the distributions in clauses
     5(b)(i) through 5(b)(iv) above, pro rata in proportion to their original
     Certificate Principal Balances.

     (c) Unless otherwise instructed by holders of Certificates representing a
majority of the Voting Rights, thirty (30) days after giving notice pursuant
to Section 8 hereof, the Trustee shall sell the Underlying Securities pursuant
to Section 13 hereof and deposit the Liquidation Proceeds, if any, into the
Certificate Account for distribution not later than two (2) Business Days
after the receipt of immediately available funds in accordance with Section
5(b) hereof; provided, however, that if any Warrant Holder designates any day
on or prior to the proposed sale date as a Call Date and Optional Exchange
Date pursuant to Section 7, the portion of Underlying Securities related to
such Optional Exchange shall not be sold but shall be distributed to the
Warrant Holder pursuant to Section 7 and the Warrant Agent Agreement.

     (d) If the Trustee receives non-cash property in respect of the
Underlying Securities as a result of a payment default on the Underlying
Securities (including from the sale thereof), the Trustee will promptly give
notice to the Depository, or for any Certificates which are not then held by
DTC or any other depository, directly to the registered holders of the
Certificates then outstanding and unpaid to the Warrant Agent. Such notice
shall state that the Trustee shall and the Trustee shall, not later than 30
days after the receipt of such property, allocate and distribute such property
to the holders of Class A-1 Certificates and Class A-2 Certificates then
outstanding and unpaid, pro rata by outstanding Certificate Principal Balance
(after deducting the costs incurred in connection therewith) in accordance
with Section 5(b) hereof. Property other than cash will be liquidated by the
Trustee, and the proceeds thereof distributed in cash, only to the extent
necessary to avoid distribution of fractional securities to
Certificateholders. In-kind distribution of such property to
Certificateholders, based on the market value of such property as of the date
of distribution to Certificateholders, will be deemed to reduce the
Certificate Principal Balance of Certificates on a dollar-for-dollar basis.

     (e) Subject to Section 9(f) hereof, to the extent Available Funds are
insufficient to make scheduled interest or principal payments on any class of
Certificates on any Distribution Date, any shortfall will be carried over and
will be distributed on the next Distribution Date (or date referred to in
Section 5(f) hereof) on which sufficient funds are available to pay such
shortfall.

                                      12
<PAGE>

     (f) If a payment with respect to the Underlying Securities is made to the
Trustee (i) after the payment date of the Underlying Securities on which such
payment was due or (ii) after the Underlying Securities are prepaid or
liquidated in whole or in part for any reason other than at their maturity,
then the Trustee will distribute any such amounts received on the next
occurring Business Day (a "Special Distribution Date") as if the funds had
constituted Available Funds on the Distribution Date immediately preceding
such Special Distribution Date; provided, however, that the Record Date for
such Special Distribution Date shall be the Business Day prior to the day on
which the related payment was received from the Underlying Securities Trustee.

     (g) Notwithstanding Section 3.12 of the Standard Terms, if the Underlying
Securities Issuer discontinues filing periodic reports required under the
Exchange Act, the Depositor shall within a reasonable time instruct the
Trustee to (i) notify the Warrant Agent that the Underlying Securities are
proposed to be sold and that any Call Warrants and related Optional Exchange
rights must be exercised no later than the date specified in the notice (which
shall be not less than ten Business Days after the date of such notice) and
(ii) to the extent that the Warrant Holders fail to exercise their Call
Warrants and related Optional Exchange rights on or prior to such date, to
sell the Underlying Securities and distribute the proceeds of such sale to the
Certificateholders in accordance with the following order of priority: first,
to the Trustee, as reimbursement for any Extraordinary Trust Expenses incurred
by the Trustee pursuant to the instruction of all of the Certificateholders;
and second, any remainder to the holders of the Class A-1 Certificates and the
Class A-2 Certificates pro rata in proportion to the ratio of the Class A-1
Allocation to the Class A-2 Allocation; provided, however, the Depositor shall
not instruct the Trustee to sell the Underlying Securities (or provide a
notice of such instruction to the Warrant Agent) pursuant to this clause
unless the Underlying Securities Issuer has either (x) stated in writing that
it intends permanently to cease filing reports required under the Exchange Act
or (y) failed to file any required reports for one full calendar year.

          (h) (i) If the Trustee receives notice of a tender offer for some or
     all of the Underlying Securities, the Trustee shall, within one Business
     Day, notify the Warrant Agent and forward to the Warrant Agent copies of
     all materials received by the Trustee in connection therewith. If the
     Trustee receives a Call Notice from any Warrant Holder no later than five
     Business Days prior to the expiration of the tender offer acceptance
     period that such Warrant Holder desires to exercise all or a portion of
     its Call Warrants in connection with the consummation of any such tender
     offer, then the Trustee shall tender, in compliance with the tender offer
     requirements, an amount of Underlying Securities equal to the amount of
     Underlying Securities that would be distributable to the Warrant Holder
     with respect to an Optional Exchange of the Called Certificates called by
     such Warrant Holder; provided that any Optional Call or Optional Exchange
     undertaken in connection with any such tender offer shall be subject to
     the provisions of Section 7 hereof.

              (ii) The Call Date and Optional Exchange Date for any exercise of
     Call Warrants in connection with a tender offer shall be deemed to be the
     Business Day on which such Underlying Securities are accepted for payment
     and paid for.

               (iii) The Call Price shall be deducted from the tender offer
     proceeds and paid to the holders of the Class A-1 Certificates and Class
     A-2 Certificates pro rata

                                      13
<PAGE>

     in accordance with the ratio of the Class A-1 Allocation to the Class A-2
     Allocation in connection with Section 7(d)(v), and the excess of the
     tender offer proceeds over the Call Price shall be paid to the exercising
     Warrant Holders pro rata in respect to their proportionate exercises of
     Call Warrants or, if the Call Price exceeds the tender offer proceeds the
     amount of such excess shall be paid by the exercising Warrant Holders pro
     rata in respect to their proportionate exercises of Call Warrants.

               (iv) If fewer than all tendered Underlying Securities are
     accepted for payment and paid for, (A) the amount of Call Warrants
     exercised shall be reduced to an amount that corresponds to a number of
     Class A-1 and Class A-2 Certificates that could be exchanged in an
     Optional Exchange for the Underlying Securities accepted for payment and
     paid for (without regard to any restrictions on the amount to be
     exchanged, so long as such restrictions would have been satisfied had all
     tendered Underlying Securities been accepted for payment and paid for);
     (B) each Warrant Holder's exercise shall be reduced by its share
     (proportionate to the amount specified in its exercise notice) of the
     amount of Underlying Securities not accepted for payment and paid for;
     (C) the Call Price shall be determined after giving effect to the
     reduction specified in clause (B); (D) the Call Warrants that relate to
     the reduction specified in clause (B) shall remain outstanding; and (E)
     the excess of the tender offer proceeds over the Call Price shall be
     allocated in proportion to the amount of Call Warrants deemed exercised
     as set forth in clause (A) above or, if the Call Price exceeds the tender
     offer proceeds the amount of such excess shall be paid by the exercising
     Warrant Holders pro rata in respect to their proportionate exercises of
     Call Warrants.

               (v) If the tender offer is terminated by the Underlying
     Securities Issuer or any other tender offeror without consummation
     thereof or if all tenders by the Trust of Underlying Securities are
     otherwise rejected, then (1) the Call Notices will be of no further force
     and effect, and (2) any Call Warrants relating to such Call Notices will
     not be exercised and will remain outstanding.

     Section 6. Trustee's Fees.

     (a) As compensation for its services hereunder, the Trustee shall be
entitled to the Trustee Fee and any amounts payable under clause 5(a)(iii) and
(5)(b)(iv) above. The Trustee Fee shall be paid by the Depositor and not from
Trust Property. The Trustee shall bear all Ordinary Expenses. Failure by the
Depositor to pay such amount shall not entitle the Trustee to any payment or
reimbursement from the Trust, nor shall such failure release the Trustee from
the duties it is required to perform under the Trust Agreement.

     (b) Extraordinary Expenses shall not be paid out of the Trust Property
unless all the holders of the Class A-1 Certificates and Class A-2
Certificates then outstanding have directed the Trustee to incur such
Extraordinary Expenses. The Trustee may incur other Extraordinary Expenses if
any lesser percentage of the Certificateholders requesting such action
pursuant hereto reimburse the Trustee for the cost thereof from their own
funds in advance. If Extraordinary Expenses are not approved unanimously as
set forth in the first sentence of this Section 6(b), such Extraordinary
Expenses shall not be an obligation of the Trust, and the

                                      14
<PAGE>

Trustee shall not file any claim against the Trust therefor notwithstanding
failure of Certificateholders to reimburse the Trustee.

     Section 7. Optional Exchange; Optional Call.

     (a) On any (i) Distribution Date, (ii) date on which a tender offer for
some or all of the Underlying Securities is consummated or (iii) date
occurring subsequent to the announcement of a Change of Control Triggering
Event (but prior to the expiration of the related Change of Control Offer),
any holder of Class A-1 Certificates and Class A-2 Certificates and the
related Call Warrants, if Call Warrants related to such Certificates are
outstanding, may exchange such Certificates and, if applicable, Call Warrants,
for a distribution of Underlying Securities representing the same percentage
of the Underlying Securities as such Certificates represent of all outstanding
Certificates. On any Call Date, any Warrant Holder may exchange Called
Certificates for a distribution of Underlying Securities representing the same
percentage of Underlying Securities as such Called Certificates represent of
all outstanding Certificates; provided, however, that any such exchange shall
either (x) result from an exercise of all Call Warrants owned by such Warrant
Holder or (y) occur on a Call Date on which such Warrant Holder, alone or
together with one or more other Warrant Holders, shall exchange Called
Certificates relating to Underlying Securities having an aggregate principal
amount equal to or in excess of the product of (i) 0.1 and (ii) the aggregate
principal amount of the Underlying Securities deposited into the Trust on the
Closing Date.

     (b) The following conditions shall apply to any Optional Exchange.

          (i) A notice specifying the number of Certificates being surrendered
     and the Optional Exchange Date shall be delivered to the Trustee no less
     than 5 days (or such shorter period acceptable to the Trustee) but not
     more than 30 days before the Optional Exchange Date; provided, however,
     that for an Optional Exchange to occur on a Call Date, unless otherwise
     specified therein, the Call Notice shall be deemed to be the notice
     required hereunder.

          (ii) Certificates and, if applicable, the Call Warrants, shall be
     surrendered to the Trustee no later than 10:00 a.m. (New York City time)
     on the Optional Exchange Date; provided that for an Optional Exchange to
     occur on a Call Date, payment of the Call Price to the Warrant Agent
     pursuant to Section 1.1(a)(iii) of the Warrant Agent Agreement shall
     satisfy the requirement to surrender Certificates.

          (iii) Class A-1 Certificates and Class A-2 Certificates representing
     a like percentage of all Class A-1 Certificates and Class A-2
     Certificates shall be surrendered.

          (iv) The Trustee shall have received an opinion of counsel stating
     that the Optional Exchange would not cause the Trust to be treated as an
     association or publicly traded partnership taxable as a corporation for
     federal income tax purposes.

          (v) If the Certificateholder is the Depositor or any Affiliate of
     the Depositor, (1) the Trustee shall have received a certification from
     the Certificateholder that any Certificates being surrendered have been
     held for at least six months, and (2) the Certificates being surrendered
     may represent no more than 5% (or 25% in the case of

                                      15
<PAGE>

     Certificates acquired by the Underwriters but never distributed to
     investors) of the then outstanding Certificates.

          (vi) The Trustee shall not be obligated to determine whether an
     Optional Exchange complies with the applicable provisions for exemption
     under Rule 3a-7 of the Investment Company Act of 1940, as amended, or the
     rules or regulations promulgated thereunder.

          (vii) The provisions of Section 4.07 of the Standard Terms shall not
     apply to an Optional Exchange pursuant to this Section 7(c). This Section
     7(c) shall not provide any person with a lien against, an interest in or
     a right to specific performance with respect to the Underlying
     Securities; provided that satisfaction of the conditions set forth in
     this Section 7(c) shall entitle the Certificateholder or Warrant Holder,
     as applicable, to a distribution thereof.

          (viii) The aggregate principal amount of Certificates exchanged in
     connection with any Optional Exchange pursuant to this Section shall be
     in an amount that will entitle the Certificateholders thereof to
     Underlying Securities in an even multiple of the minimum denomination of
     such Underlying Securities.

          (ix) In the event such Optional Exchange shall occur prior to the
     Distribution Date in December, 2002, the Certificateholders shall have
     paid to the Trustee, for distribution to the Depositor, on the Optional
     Exchange Date an amount equal to the sum obtained by multiplying the
     amount of accrued interest on the Underlying Securities from June 1, 2002
     through, but excluding, the Closing Date by a fraction, the numerator of
     which shall be the number of Certificates being exchanged on such
     Optional Exchange Date and the denominator of which shall be the total
     number of Certificates.

     (c) Concurrently with the execution of this Series Supplement, the
Trustee, on behalf of the Trust, shall execute the Warrant Agent Agreement and
the Call Warrants, dated as of the date hereof and substantially in the form
of Exhibit B hereto, initially evidencing all of the Call Warrants. The
Trustee shall perform the Trust's obligations under the Warrant Agent
Agreement and the Call Warrants in accordance with their respective terms.

     (d) Call Warrants may be exercised by the Warrant Holder in whole or in
part on any Call Date. In addition to the conditions set forth in Section 1.1
of the Warrant Agent Agreement, the following conditions shall apply to any
Optional Call.

          (i) An opinion of counsel to the Warrant Holder shall have been
     delivered to the Rating Agencies, in form satisfactory to the Rating
     Agencies, indicating that payment of the Call Price shall not be
     recoverable as a preferential transfer or fraudulent conveyance under the
     United States Bankruptcy Code. Such opinion may contain customary
     assumptions and qualifications.

          (ii) The Warrant Holder shall have provided a certificate of
     solvency to the Trustee.

                                      16

          (iii) Upon receipt of a Call Notice, the Trustee shall provide a
     conditional call notice to the Depository not less than 3 Business Days
     prior to the Call Date.

          (iv) Delivery of a Call Notice does not give rise to an obligation
     on the part of the Warrant Holder to pay the Call Price. If, by 10:00
     a.m. (New York City time) on the Call Date, the Warrant Holder has not
     paid the Call Price (except in connection with a Call Notice relating to
     a tender offer for the Underlying Securities), then the Call Notice shall
     automatically expire and none of the Warrant Holder, the Warrant Agent or
     the Trustee shall have any obligation with respect to the Call Notice.
     The expiration of a Call Notice shall in no way affect the Warrant
     Holder's right to deliver a Call Notice at a later date. The Call Price
     for a call in connection with a tender offer shall be deducted from the
     proceeds of a tender offer by the Trust pursuant to Section 5(g)(iii).

          (v) Subject to receipt of the Call Price, the Trustee shall pay the
     Call Price to the Certificateholders on the Call Date. The Call Price for
     Class of Certificates in respect of partial calls shall be allocated pro
     rata to the Certificateholders of such Class.

          (vi) The Trustee shall not consent to any amendment or modification
     of this Agreement (including the Standard Terms) which would adversely
     affect the Warrant Holders (including, without limitation, any alteration
     of the timing or amount of any payment of the Call Price or any other
     provision of this Agreement in a manner adverse to the Warrant Holders)
     without the prior written consent of 100% of the Warrant Holders. For
     purposes of this clause, no amendment, modification or supplement
     required to provide for any purchase by the Trustee of additional
     Underlying Securities and authentication and delivery by the Trustee of
     additional certificates and call warrants pursuant to Section 3(d) shall
     be deemed to adversely affect the Warrant Holders.

          (vii) The Trustee shall not be obligated to determine whether an
     Optional Call complies with the applicable provisions for exemption under
     Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules
     or regulations promulgated thereunder.

     (e) This Section 7 shall not provide the Warrant Holder with a lien
against, an interest in or a right to specific performance with respect to the
Underlying Securities.

     (f) The rights of the Certificateholders under the Trust Agreement and
the Certificates are limited by the terms, provisions and conditions of the
Trust Agreement, the Warrant Agent Agreement and the Call Warrants with
respect to the exercise of the Call Warrants by the Warrant Holder. The
Certificateholders, by their acceptance of Certificates, covenant and agree to
tender any and all Called Certificates to the Trustee upon the Warrant
Holder's exercise of Call Warrants and payment of the Call Price for such
Certificates in accordance with the provisions hereof and of the Warrant Agent
Agreement.

     Section 8. Notices of Events of Default.

          As promptly as practicable after, and in any event within 30 days
after, the occurrence of any Event of Default actually known to the Trustee,
the Trustee shall give notice of such Event of Default to the Depository, or,
if any Certificates are not then held by DTC or any other depository, directly
to the registered holders of such Certificates and to the Warrant

                                      17
<PAGE>

Agent. However, except in the case of an Event of Default relating to the
payment of principal of or interest on any of the Underlying Securities, the
Trustee will be protected in withholding such notice if in good faith it
determines that the withholding of such notice is in the interest of the
Certificateholders.

Period on the Underlying Securities on or prior to the related Distribution
Date, such distribution will be made promptly upon receipt of such payment. No
additional amounts shall accrue on the Certificates or be owed to
Certificateholders as a result of such delay; provided, however, that any
additional interest owed and paid by the Underlying Securities Issuer as a
result of such delay shall be paid to the Class A-1 Certificateholders pro
rata in proportion to their respective entitlements to such delayed payments.

     (g) The outstanding Certificate Principal Balance of the Certificates
shall not be reduced by the amount of any Realized Losses (as defined in the
Standard Terms).

     (h) The Trust may not engage in any business or activities other than in
connection with, or relating to, the holding, protecting and preserving of the
Trust Property and the issuance of the Certificates and the Call Warrants, and
other than those required or authorized by the Trust Agreement or incidental
and necessary to accomplish such activities. The Trust may not issue or sell

Warrants or otherwise incur, assume or guarantee any indebtedness for money
borrowed. Notwithstanding Section 3.05 of the Standard Terms, funds on deposit
in the Certificate Account shall not be invested. Section 2.01(f) of the
Standard Terms shall be superseded by this provision.

     (i) Notwithstanding anything in the Trust Agreement to the contrary, the

characterization of the Trust as a grantor trust, the Trustee shall then file
such forms as the Depositor may specify to

                                      18
<PAGE>

establish the Trust's election pursuant to Section 761 of the Code to exclude
the Trust from the application of Subchapter K of the Code and is hereby
empowered to execute such forms on behalf of the Certificateholders.

     (k) Notwithstanding anything in the Standard Terms to the contrary, the
Trustee, upon written direction by the Depositor, will execute the
Certificates.

     (l) In relation to Section 7.01(f) of the Standard Terms, any periodic
reports filed by the Trustee pursuant to the Exchange Act in accordance with
the customary practices of the Depositor, need not contain any independent
reports.

     (m) Notwithstanding anything in the Trust Agreement to the contrary, the
Trustee will have no recourse to the Underlying Securities.

     (n) The Trustee shall promptly notify each Rating Agency upon its
obtaining actual knowledge of the occurrence of a Defeasance (as defined in
the Indenture) with respect to the Underlying Securities Issuer.

     (o) The Trust will not merge or consolidate with any other entity without
confirmation from each Rating Agency that such merger or consolidation will
not result in the qualification, reduction or withdrawal of its then-current
rating on the Certificates.

         "at the time of delivery of the Underlying Securities, the Depositor

         interest in such Underlying Securities and such Underlying Securities
         are free and clear of any lien, pledge, encumbrance, right, charge,
         claim or other security interest; and"

     Section 10. Governing Law. THIS SERIES SUPPLEMENT AND THE TRANSACTIONS
DESCRIBED HEREIN SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED
WITHIN THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS

                                      20
<PAGE>

     Section 12. Termination of the Trust. The Trust shall terminate upon the
earliest to occur of (i) the payment in full at maturity or sale by the Trust
after a payment default or an acceleration or other early payment of the
Underlying Securities and the distribution in full of all amounts due to the
Class A-1 Certificateholders and Class A-2 Certificateholders; (ii) the
exercise of all outstanding Call Warrants by the Warrant Holder; (iii) the
Final Scheduled Distribution Date and (iv) the expiration of 21 years from the
death of the last survivor of the descendants of Joseph P. Kennedy, the late
Ambassador of the United States to the Court of St. James, living on the date
hereof.

     Section 13. Sale of Underlying Securities; Optional Exchange. In the
event of a sale of the Underlying Securities pursuant to Section 5(c) hereof
or pursuant to the instructions of the Warrant Agent under Section 1.2 of the
Warrant Agent Agreement, the Trustee shall solicit bids for the sale of the
Underlying Securities with settlement thereof on or before the third (3rd)
Business Day after such sale from three leading dealers in the relevant
market. Any of the following dealers (or their successors) shall be deemed to
qualify as leading dealers: (1) Credit Suisse First Boston Corporation, (2)
Goldman, Sachs & Co., (3) Merrill Lynch, Pierce, Fenner & Smith Incorporated,
(4) UBS Warburg LLC, (5) Salomon Smith Barney Inc., and (6) except in the case
of a sale related to the exercise of Call Warrants by the Depositor or any
Affiliate thereof, Lehman Brothers Inc. The Trustee shall not be responsible
for the failure to obtain a bid so long as it has made reasonable efforts to
obtain bids. If a bid for the sale of the Underlying Securities has been
accepted by the Trustee but the sale has failed to settle on the proposed
settlement date, the Trustee shall request new bids from such leading dealers.
In the event of an Optional Exchange, the Trustee shall only deliver the
Underlying Securities to the purchaser of such Underlying Securities or sell
the Underlying Securities pursuant to this Section 13, as the case may be,
against payment in same day funds deposited into the Certificate Account.

     Section 14. Amendments. Notwithstanding anything in the Trust Agreement
to the contrary, in addition to the other restrictions on modification and
amendment contained therein, the Trustee shall not enter into any amendment or
modification of the Trust Agreement which would adversely affect in any
material respect the interests of the holders of any class of Certificates
without the consent of the holders of 100% of such class of Certificates;
provided, however, that no such amendment or modification will be permitted
which would cause the Trust to be taxed as an association or publicly traded
partnership taxable as a corporation for federal income tax purposes. Unless
otherwise agreed, the Trustee shall provide five Business Days written notice
to each Rating Agency before entering into any amendment or modification of
the Trust Agreement pursuant to this Section 14.

     Section 15. Voting of Underlying Securities, Modification of Indenture.

     (a) The Trustee, as holder of the Underlying Securities, has the right to
vote and give consents and waivers in respect of the Underlying Securities as
permitted by the Depository and except as otherwise limited by the Trust
Agreement. In the event that the Trustee receives a request from the
Depository, the Underlying Securities Trustee or the Underlying Securities
Issuer for its consent to any amendment, modification or waiver of the
Underlying Securities, the Indenture or any other document thereunder or
relating thereto, or receives any other solicitation for any action with
respect to the Underlying Securities, the Trustee shall mail a notice of such
proposed amendment, modification, waiver or solicitation to each
Certificateholder of record as

                                      21
<PAGE>

of such date. The Trustee shall request instructions from the
Certificateholders as to whether or not to consent to or vote to accept such
amendment, modification, waiver or solicitation. The Trustee shall consent or
vote, or refrain from consenting or voting, in the same proportion (based on
the relative outstanding Certificate Principal Balances of the Certificates)
as the Certificates of the Trust were actually voted or not voted by the
Certificateholders thereof as of a date determined by the Trustee prior to the
date on which such consent or vote is required; provided, however, that,
notwithstanding anything in the Trust Agreement to the contrary, the Trustee
shall at no time vote on or consent to any matter (i) unless such vote or
consent would not (based on an opinion of counsel) cause the Trust to be taxed
as an association or publicly traded partnership taxable as a corporation
under the Code, (ii) which would alter the timing or amount of any payment on
the Underlying Securities, including, without limitation, any demand to
accelerate the Underlying Securities, except in the event of a default under
the Underlying Securities or an event which with the passage of time would
become an event of default under the Underlying Securities and with the
unanimous consent of holders of all outstanding Class A-1 Certificates, Class
A-2 Certificates and all Warrant Holders, or (iii) which would result in the
exchange or substitution of any of the outstanding Underlying Securities
pursuant to a plan for the refunding or refinancing of such Underlying
Securities except in the event of a default under the Indenture and only with
the consent of Certificateholders representing 100% of the Class A-1
Certificates, 100% of the Class A-2 Certificates and 100% of the Warrant
Holders. The Trustee shall have no liability for any failure to act resulting
from Certificateholders' late return of, or failure to return, directions
requested by the Trustee from the Certificateholders.

     (b) In the event that an offer is made by the Underlying Securities
Issuer to issue new obligations in exchange and substitution for any of the
Underlying Securities, pursuant to a plan for the refunding or refinancing of
the outstanding Underlying Securities or any other offer is made for the
Underlying Securities, the Trustee shall notify the Class A-1
Certificateholders, Class A-2 Certificateholders and the Warrant Holders of
such offer promptly. Subject to the rights of the Warrant Holders to exercise
Call Warrants in connection with a tender offer or Change of Control Offer for
the Underlying Securities, the Trustee must reject any such offer unless the
Trustee is directed by the affirmative vote of the holders of 100% of the
Class A-1 Certificates, Class A-2 Certificates and Call Warrants to accept
such offer and the Trustee has received the tax opinion described above. If
pursuant to the preceding sentence, the Trustee accepts any such offer the
Trustee shall promptly notify the Rating Agencies.

     (c) If an event of default under the Indenture occurs and is continuing,
and if directed by a majority of the outstanding Class A-1 Certificateholders
and Class A-2 Certificateholders, the Trustee shall vote the Underlying
Securities in favor of directing, or take such other action as may be
appropriate to direct, the Underlying Securities Trustee to declare the unpaid
principal amount of the Underlying Securities and any accrued and unpaid
interest thereon to be due and payable.

     (d) Subject to the rights of the Warrant Holders pursuant to Section 5(h)
hereof, the Trustee shall not tender Underlying Securities on behalf of the
Trust in connection with a Change of Control Offer, regardless of any vote or
direction of the Certificateholders to the contrary.

                                      22

     Additional Depositor Representation. It is the express intent of the
parties hereto that the conveyance of the Underlying Securities by the
Depositor to the Trustee be, and be construed as, a sale of the Underlying
Securities by the Depositor and not a pledge of any Underlying Securities by
the Depositor to secure a debt or other obligation of the Depositor. In the
event that, notwithstanding the aforementioned intent of the parties, any
Underlying Securities are held to be property of the Depositor, then, it is
the express intent of the parties that such conveyance be deemed a pledge of
such Underlying Securities by the Depositor to the Trustee to secure a debt or
other obligation of the Depositor, pursuant to Section 10.07 of the Standard
Terms. In connection with any such grant of a security interest in the
Underlying Securities (including any such grant in connection with any sale of
additional Underlying Securities pursuant to Section 3(d)), the Depositor
hereby represents and warrants to Trustee as follows:

     (i)    In the event the Underlying Securities are held to be property of
            the Depositor, then the Trust Agreement creates a valid and
            continuing security interest (as defined in the applicable Uniform
            Commercial Code) in the Underlying Securities in favor of the
            Trustee which security interest is prior to all other liens, and
            is enforceable as such as against creditors of, and purchasers
            from, the Depositor.

     (ii)   The Underlying Securities have been credited to a trust account
            (the "Securities Account") of the Trustee, or its authorized
            agent, in accordance with Section 2.01 of the Standard Terms. The
            Trustee, as securities intermediary for the Securities Account,
            has agreed to treat the Underlying Securities as "financial
            assets" within the meaning of the Uniform Commercial Code.

     (iii)  Immediately prior to the transfer of the Underlying Securities to
            the Trust, Depositor owned and had good and marketable title to
            the Underlying Securities free and clear of any lien, claim or
            encumbrance of any Person.

     (iv)   Depositor has received all consents and approvals required by the
            terms of the Underlying Securities to the transfer to the Trustee
            of its interest and rights in the Underlying Securities as
            contemplated by the Trust Agreement.

     (v)    Depositor has taken all steps necessary to cause the Trustee, as
            securities intermediary for the Securities Account, to identify on
            its records that the Trustee, as the trustee of the Trust, is the
            Person having a security entitlement against the securities
            intermediary in the Securities Account.

     (vi)   Depositor has not assigned, pledged, sold, granted a security
            interest in or otherwise conveyed any interest in the Underlying
            Securities (or, if any such interest has been assigned, pledged or
            otherwise encumbered, it has been released). Depositor has not
            authorized the filing of and is not aware of any financing
            statements against Depositor that includes a description of the
            Underlying Securities. Depositor is not aware of any judgment or
            tax lien filings against Depositor.

                                      23
<PAGE>

     (vii)  The Securities Account is not in the name of any Person other than
            the Trust. Depositor has not consented to the compliance by the
            Trustee, as securities intermediary, with entitlement orders of
            any Person other than the Trustee, as trustee of the Trust.

                                      24

          IN WITNESS WHEREOF, the parties hereto have caused this Series

                              SERIES 2002-9 TRUST

     WARRANT AGENT AGREEMENT, dated as of June 3, 2002 (the "Warrant Agent
Agreement"), by and between LEHMAN ABS CORPORATION, as Depositor (the

Agent").

                             W I T N E S S E T H:

     WHEREAS, the Depositor created Corporate Backed Trust Certificates, News
America Debenture-Backed Series 2002-9 Trust (the "Trust"), a trust created
under the laws of the State of New York pursuant to a Standard Terms for Trust
Agreements, dated as of January 16, 2001 (the "Agreement"), between the
Depositor and U.S. Bank Trust National Association, a national banking
association, not in its individual capacity but solely as Trustee (the
"Trustee"), as supplemented by the Series Supplement, News America
Debenture-Backed Series 2002-9, dated as of June 3, 2002 (the "Series
Supplement" and, together with the Agreement, the "Trust Agreement"), between
the Depositor and the Trustee; and

     WHEREAS, in connection with the creation of the Trust and the deposit
therein of the Underlying Securities, it is desired to provide for the
issuance of trust certificates (the "Certificates") evidencing undivided
interests in the Trust and call warrants with respect to the Certificates
("Call Warrants").

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants expressed herein, it is hereby agreed by and between the Depositor,
the Warrant Agent and the Trustee that except as otherwise specified herein or
as the context may otherwise require, capitalized terms used herein but not
defined herein shall have the respective meanings set forth in the Series
Supplement, and as follows:

                                  ARTICLE I

                           EXERCISE OF CALL WARRANTS

     Section 1.1 Manner of Exercise. (a) Call Warrants may be exercised by any
holder thereof (each, a "Warrant Holder") in whole or in part on any Call
Date. The following conditions shall apply to any exercise of Call Warrants:

               (i) A notice (each, a "Call Notice") specifying the number of
          Call Warrants being exercised and the Call Date shall be delivered
          to the Warrant Agent and the Trustee at least 5 Business Days before
          such Call Date.

<PAGE>

               (ii) The Warrant Holder shall surrender the Call Warrants to
          the Warrant Agent at its office specified in Section 6.3 hereof no
          later than 10:00 a.m. (New York City time) on such Call Date.

               (iii) The Warrant Holder shall have made payment to the Warrant
          Agent, by wire transfer or other immediately available funds
          acceptable to the Warrant Agent, in the amount of the Call Price, no
          later than 10:00 a.m. (New York City time) on the Call Date.

               (iv) The Warrant Holder shall exercise Call Warrants relating to
          Class A-1 Certificates and Call Warrants relating to Class A-2
          Certificates which represent a like percentage of all Class A-1
          Certificates and Class A-2 Certificates.

               (v) The Warrant Holder may not exercise the Call Warrants at
          any time when such Warrant Holder is insolvent, and such Warrant
          Holder shall be required to certify that it is solvent at the time
          of exercise, by completing the Form of Subscription attached to the
          Call Warrants and delivering such completed Form of Subscription to
          the Trustee on or prior to the Call Date and by delivering to the
          Trustee a form reasonably satisfactory to the Trustee of the opinion
          and the solvency certificate required pursuant to Section 7(d)(ii)
          of the Series Supplement.

               (vi) The Warrant Holder shall have satisfied any other
          conditions to the exercise of Call Warrants set forth in Section
          7(b) of the Series Supplement.

          (b) Upon exercise of Call Warrants, any Warrant Holder other than
the Depositor or any Affiliate of the Depositor shall be entitled to delivery
by the Trustee of the Called Certificates. The "Called Certificates" shall be,
in the case of the Class A-1 Certificates, Class A-1 Certificates having a
Certificate Principal Amount equal to $25 per Call Warrant, and in the case of
the Class A-2 Certificates, Class A-2 Certificates having a Certificate
Principal Amount equal to $100,000 per Call Warrant. Unless otherwise
specified therein, such Call Notice shall be deemed to be notice of an
Optional Exchange pursuant to Section 7(a) of the Series Supplement. Any
Warrant Holder which is the Depositor or any Affiliate of the Depositor shall
receive the proceeds of the sale of the Called Underlying Securities and shall
not be entitled to receive the related Called Certificates or Called
Underlying Securities. "Called Underlying Securities" are Underlying
Securities which represent the same percentage of the Underlying Securities as
the Called Certificates represent of the Class A-1 Certificates and the Class
A-2 Certificates.

          (c) The Warrant Agent shall notify the Trustee immediately upon its
receipt of a Call Notice and upon receipt of payment of the Call Price. The
Warrant Agent shall transfer the amount of any paid Call Price to the Trustee
in immediately available funds, for deposit in the Certificate Account and
application pursuant to the Trust Agreement on the applicable Call Date (and,
pending such transfer, shall hold such amount for the benefit of the Warrant
Holder in a segregated trust account).

                                      2
<PAGE>

          (d) Delivery of a Call Notice does not give rise to an obligation on
part of the Warrant Holder to pay the Call Price. If, by 10:00 a.m. (New York
City time) on the Call Date, the Warrant Holder has not paid the Call Price,
except in connection with a Call Notice relating to a tender offer for
Underlying Securities, then the Call Notice shall automatically expire and
none of the Warrant Holder, the Warrant Agent or the Trustee shall have any
obligation with respect to the Call Notice. The expiration of a Call Notice
shall in no way affect the Warrant Holder's right to deliver a Call Notice at
a later date. The Call Price for a call in connection with a tender offer
shall be deducted from the proceeds of a tender offer by the Trust pursuant to
Section 7(g)(iii) of the Series Supplement.

     Section 1.2 Transfer of Certificates. As soon as practicable after each
surrender of Call Warrants in whole or in part on the Call Date and upon
satisfaction of all other requirements described in the Call Warrants and in
Section 1.1 hereof, the Warrant Agent shall instruct the Trustee as follows:

               (a) if Call Warrants are being exercised by any Warrant Holder
other than the Depositor or any Affiliate of the Depositor, to cause the
Called Certificates to reflect the Warrant Holder's beneficial ownership of
such Certificates and if such Call Notice is also deemed to be a notice of
Optional Exchange, to cause a distribution of Underlying Securities to the
Warrant Holder in accordance with Section 7(a) of the Series Supplement,
provided, however, that if such a Call Notice and Optional Exchange is in
connection with a tender offer, the Warrant Agent shall instruct the Trustee
to distribute to the exercising Warrant Holder the excess of the tender offer
proceeds over the Call Price pursuant to Section 7(g)(iii) of the Series
Supplement, or

          (b) if the Call Warrants are being exercised by the Depositor or any
Affiliate of the Depositor, to cause the Called Underlying Securities to be
sold pursuant to Section 13 of the Series Supplement and to distribute the
proceeds of such sale to the Warrant Holder.

     If such exercise is in part only, the Warrant Agent shall instruct the
Trustee to authenticate new Call Warrants of like tenor, representing the
outstanding Call Warrants of the Warrant Holder and the Warrant Agent shall
deliver such Call Warrants to the Warrant Holder.

     In each case, the Trustee shall act in accordance with such instructions.

     Section 1.3 Cancellation and Destruction of Call Warrants. All Call
Warrants surrendered to the Warrant Agent for the purpose of exercise (in
whole or in part) pursuant to Section 1.1 and actually exercised, or for the
purpose of transfer or exchange pursuant to Article III, shall be cancelled by
the Warrant Agent, and no Call Warrant (other than that reflecting any such
transfer or exchange) shall be issued in lieu thereof. The Warrant Agent shall
destroy all cancelled Call Warrants.

     Section 1.4 No Rights as Holder of Certificates Conferred by Call
Warrants. Prior to the exercise thereof, Call Warrants shall not entitle the
Warrant Holder to any of the rights of a holder of the Certificates,
including, without limitation, the right to receive the payment of any amount
on or in respect of the Certificates or to enforce any of the covenants of the
Trust Agreement.

                                      3
<PAGE>

     Section 1.5 Pro Rata Reduction of Call Warrants if Partial Redemption of
Underlying Securities. If Underlying Securities are redeemed in part by the
Underlying Securities Issuer and the Warrant Holders do not exercise their
Call Rights in connection with such partial redemption, the number of Call
Warrants held by each Warrant Holder shall be reduced proportionately so that
the aggregate amount of Class A-1 Certificates callable by Call Warrants shall
equal the amount of outstanding Class A-1 Certificates after giving effect to
such partial redemption and the aggregate Certificate Principal Amount of
Class A-2 Certificates callable by Call Warrants shall equal the outstanding
Certificate Principal Amount of Class A-2 Certificates after giving effect to
such partial redemption. The Warrant Agent shall make such adjustments to its
records as shall be necessary to reflect such reductions and shall notify each
Warrant Holder of such adjustments.

                                  ARTICLE II

                           RESTRICTIONS ON TRANSFER

     Section 2.1 Restrictive Legends. Except as otherwise permitted by this
Article II, each Call Warrant (including each Call Warrant issued upon the
transfer of any Call Warrant) shall be issued with a legend in substantially
the following form:

     "This Call Warrant has not been registered under the Securities Act of
1933, as amended, and may not be transferred, sold or otherwise disposed of
except while a registration under such Act is in effect or pursuant to an
exemption therefrom under such Act. The Call Warrant represented hereby may be
transferred only in compliance with the conditions specified in the Call
Warrants."

     Section 2.2 Notice of Proposed Transfer; Opinions of Counsel. Prior to
any transfer of any Call Warrant or portion thereof, the Warrant Holder will
give 5 Business Days (or such lesser period acceptable to the Warrant Agent)
prior written notice to the Warrant Agent of such Warrant Holder's intention
to effect such transfer.

                                 ARTICLE III

               REGISTRATION AND TRANSFER OF CALL WARRANTS, ETC.

     Section 3.1 Warrant Register; Ownership of Call Warrants. The Warrant
Agent will keep a register in which the Warrant Agent will provide for the
registration of Call Warrants and the registration of transfers of Call
Warrants representing numbers of Call Warrants. The Trustee and the Warrant
Agent may treat the Person in whose name any Call Warrant is registered on
such register as the owner thereof for all purposes, and the Trustee and the
Warrant Agent shall not be affected by any notice to the contrary.

     Section 3.2 Transfer and Exchange of Call Warrants. (a) No Call Warrant
may be offered, resold, assigned or otherwise transferred (including by pledge
or hypothecation) at any time prior to (x) the date which is two years or such
shorter period of time as permitted by Rule 144(k) under the Securities Act
after the later of the original issue date of such Call Warrants and the last
date on which the Depositor or any "affiliate" (as defined in Rule 144 under
the

                                      4
<PAGE>

Securities Act) of the Depositor was the owner of such Call Warrant (or any
predecessor thereto) or (y) or such later date, if any, as may be required by
a change in applicable securities laws (the "Resale Restriction Termination
Date") unless such offer, resale, assignment or transfer is (i) to the Trust,
(ii) pursuant to an effective registration statement under the Securities Act,
(iii) to a qualified institutional buyer (a "QIB"), as such term is defined in
Rule 144A promulgated under the Securities Act ("Rule 144A"), in accordance
with Rule 144A or (iv) pursuant to another available exemption from
registration provided under the Securities Act, and, in each of cases (i)
through (iv), in accordance with any applicable securities laws of any state

(iii) above, the prospective transferee and the prospective transferor shall
be required to deliver to the Trustee an executed copy of an Investment Letter
with respect to the Call Warrants to be transferred substantially in the form
of Exhibit A hereto. Prior to any offer, resale, assignment or transfer of any
Call Warrants in the manner described in clause (iv) above, the prospective
transferee and the prospective transferor shall be required to deliver to the
Trustee documentation certifying that the offer, resale, assignment or
transfer complies with the provisions of said clause (iv). In addition to the
foregoing, each prospective transferee of any Call Warrants in the manner
contemplated by clause (iii) above shall acknowledge, represent and agree as
follows:

     (1)  The transferee (x) is a QIB, (y) is aware that the sale to it is
          being made in reliance on Rule 144A and (z) is acquiring such Call
          Warrant for its own account or for the account of a QIB.

     (2)  The transferee understands that the Call Warrant are being offered
          in a transaction not involving any public offering in the United
          States within the meaning of the Securities Act, and that the Call
          Warrants have not been and will not be registered under the
          Securities Act.

     (3)  The transferee agrees that (A) if in the future it decides to offer,
          resell, pledge or otherwise transfer the Call Warrants prior to the
          Resale Restriction Termination Date, such Call Warrants shall only
          be offered, resold, assigned or otherwise transferred (i) to the
          Trust, (ii) pursuant to an effective registration statement under
          the Securities Act, (iii) to a QIB, in accordance with Rule 144A or
          (iv) pursuant to another available exemption from registration
          provided under the Securities Act, and, in each of cases (i) through
          (iv), in accordance with any applicable securities laws of any state
          of the United States and other jurisdictions and (B) the transferee
          will, and each subsequent holder is required to, notify any
          subsequent purchaser of such Call Warrants from it of the resale
          restrictions referred to in clause (A) above.

     (b) Upon surrender of any Call Warrants for registration of transfer or
for exchange to the Warrant Agent, the Warrant Agent shall (subject to
compliance with Article II) execute and deliver, and cause the Trustee, on
behalf of the Trust, to execute and deliver, in exchange therefor, a new Call
Warrant of like tenor and evidencing a like number of Call Warrants, in the
name of such Warrant Holder or as such Warrant Holder (upon payment by such
Warrant Holder of any applicable transfer taxes or government charges) may
direct; provided that as a condition precedent for transferring the Call
Warrants, the prospective transferee shall deliver to the

                                      5
<PAGE>

Trustee and the Depositor an executed copy of the Investment Letter (set forth
as Exhibit A hereto), if the same is required pursuant to the provisions of
clause (a) above.

     Section 3.3 Replacement of Call Warrants. Upon receipt of evidence
reasonably satisfactory to the Warrant Agent of the loss, theft, destruction
or mutilation of any Call Warrant and, in the case of any such loss, theft or
destruction of any Call Warrant, upon delivery of an indemnity bond in such
reasonable amount as the Warrant Agent may determine, or, in the case of any
such mutilation, upon the surrender of such Call Warrant for cancellation to
the Warrant Agent, the Warrant Agent shall execute and deliver, and cause the
Trustee, on behalf of the Trust, to execute and deliver, in lieu thereof, a
new Call Warrant of like tenor bearing a number not contemporaneously
outstanding.

     Section 3.4 Execution and Delivery of Call Warrants by Trustee. The
Trustee, on behalf of the Trust, hereby agrees (subject to compliance with
Article II) to execute and deliver such new Call Warrants issued in accordance
with Section 1.2 or this Article III as the Warrant Agent shall request in

     Section 5.2 Duties of Warrant Agent. The Warrant Agent undertakes only
the specific duties and obligations imposed hereunder upon the following terms
and conditions, by all of which the Depositor, the Trust, the Trustee and each
Warrant Holder shall be bound:

          (a) The Warrant Agent may consult with legal counsel (who may be
legal counsel for the Depositor), and the opinion of such counsel shall be
full and complete authorization and protection to the Warrant Agent as to any
action taken or omitted by it in good faith and in accordance with such
opinion, provided the Warrant Agent shall have exercised reasonable care in
the selection by it of such counsel.

          (b) Whenever in the performance of its duties hereunder, the Warrant
Agent shall deem it necessary or desirable that any fact or matter be proved
or established by the Depositor or the Trustee prior to taking or suffering
any action hereunder, such fact or matter may be deemed to be conclusively
proved and established by a Depositor Order or a certificate signed by a
Responsible Officer of the Trustee and delivered to the Warrant Agent; and
such certificate shall be full authorization to the Warrant Agent for any
action taken or suffered in good faith by it hereunder in reliance upon such
certificate.

          (c) The Warrant Agent shall be liable hereunder only for its own
negligence, willful misconduct or bad faith.

          (d) The Warrant Agent shall not be liable for or by reason of any of
the statements of fact or recitals contained herein or be required to verify
the same, but all such statements and recitals are and shall be deemed to have
been made by the Trust and the Depositor only.

          (e) The Warrant Agent shall not have any responsibility in respect
of and makes no representation as to the validity of the Call Warrants or the
execution and delivery thereof (except the due execution hereof by the Warrant
Agent); nor shall it be responsible for any breach by the Trust of any
covenant or condition contained in the Call Warrants; nor shall it by any act
thereunder be deemed to make any representation or warranty as to the
Certificates to be purchased thereunder.

          (f) The Warrant Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the Chief Executive Officer, Chief Financial Officer,
Chief Operating Officer, President, a Vice President, a Senior Vice President,
a Managing Director, its Treasurer, an Assistant Treasurer, its Secretary or
an Assistant Secretary of the Depositor, and any Responsible Officer of the
Trustee, and to apply to such officers for advice or instructions in
connection with its duties, and it shall not be liable for any action taken or
suffered to be taken by it in good faith in accordance with instructions of
any such officer.

          (g) The Warrant Agent and any shareholder, director, officer or
employee of the Warrant Agent may buy, sell or deal in any of the Call
Warrants or other securities of the Trust or otherwise act as fully and freely
as though it were not Warrant Agent hereunder, so long as such persons do so
in full compliance with all applicable laws. Nothing herein shall preclude the

                                      8
<PAGE>

Warrant Agent from acting in any other capacity for the Trust, the Depositor
or for any other legal entity.

          (h) The Warrant Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by
or through its attorneys or agents.

          (i) The Warrant Agent shall act solely as the agent of the Trust
hereunder. The Warrant Agent shall not be liable except for the failure to
perform such duties as are specifically set forth herein, and no implied
covenants or obligations shall be read into the Call Warrants against the
Warrant Agent, whose duties shall be determined solely by the express
provisions thereof. The Warrant Agent shall not be deemed to be a fiduciary.

          (j) The Warrant Agent shall not be responsible for any failure on
the part of the Trustee to comply with any of its covenants and obligations
contained herein.

          (k) The Warrant Agent shall not be under any obligation or duty to
institute, appear in or defend any action, suit or legal proceeding in respect
hereof, unless first indemnified to its satisfaction, but this provision shall
not affect the power of the Warrant Agent to take such action as the Warrant
Agent may consider proper, whether with or without such indemnity. The Warrant
Agent shall promptly notify the Depositor and the Trustee in writing of any
claim made or action, suit or proceeding instituted against it arising out of
or in connection with the Call Warrants.

          (l) The Trustee will perform, execute, acknowledge and deliver or

discharged from its duties hereunder upon thirty (30) days notice in writing
mailed to the Depositor and the Trustee by registered or certified mail, and
to the Warrant Holders by first-class mail at the expense of the Depositor;
provided that no such resignation or discharge shall become effective until a
successor Warrant Agent shall have been appointed hereunder. The Depositor may
remove the Warrant Agent or any successor Warrant Agent upon thirty (30) days
notice in writing, mailed to the Warrant Agent or successor Warrant Agent, as
the case may be, and to the Warrant Holders by first-class mail; provided,
further, that no such removal shall become effective until a successor Warrant
Agent shall have been appointed hereunder. If the Warrant Agent shall resign
or be removed or shall otherwise become incapable of acting, the Depositor
shall promptly appoint a successor to the Warrant Agent, which may be
designated as an interim Warrant Agent. If an interim Warrant Agent is
designated, the Depositor shall then appoint a permanent successor to the
Warrant Agent, which may be the interim Warrant Agent. If the Depositor shall
fail to make such appointment of a permanent successor within a period of
thirty (30) days after such removal or within sixty (60) days after

fee of $50.00 upon the issue of any new Call Warrant, such fee to be assessed
upon the new Call Warrant Holder.

                                 MISCELLANEOUS

     Section 6.1 Remedies. The remedies at law of the Warrant Holder in the
event of any default or threatened default by the Warrant Agent in the
performance of or compliance with any of the terms of the Call Warrants are
not and will not be adequate and, to the full extent permitted by law, such
terms may be specifically enforced by a decree for the specific performance of
any agreement contained herein or by an injunction against a violation of any
of the terms thereof or otherwise.

     Section 6.2 Limitation on Liabilities of Warrant Holder. Nothing
contained in this Warrant Agent Agreement shall be construed as imposing any
obligation on the Warrant Holder to purchase any of the Certificates except in
accordance with the terms thereof.

     Section 6.3 Notices. All notices and other communications under this
Warrant Agent Agreement shall be in writing and shall be delivered, or mailed
by registered or certified mail, return receipt requested, by a nationally

such other address notice of which the Warrant Agent shall have given to the
Warrant Holder and the Trustee or (c) if to the Trust or the Trustee, to the

the exercise of any Call Warrants shall be effective in the manner provided in
Article I. The Warrant Agent shall forward to the Warrant Holder any notices
received by it hereunder or pursuant to the Trust Agreement or this Agreement
by facsimile within one Business Day of receipt thereof.

     Section 6.4 Amendment. (a) This Warrant Agent Agreement may be amended
from time to time by the Depositor, the Trustee and the Warrant Agent without
the consent of any Warrant Holder, upon receipt of an opinion of counsel
satisfactory to the Warrant Agent that the provisions hereof have been
satisfied and that such amendment would not cause the Trust to be taxed as an
association or publicly traded partnership taxable as a Corporation under the
Code, for any of the following purposes: (i) to cure any ambiguity or to
correct or supplement any provision herein which may be defective or
inconsistent with any other provision herein or to provide for any other terms
or modify any other provisions with respect to matters or questions arising
under the Call Warrant which shall not adversely affect in any material
respect the interests of the Warrant Holder or any holder of a Certificate or
(ii) to evidence and provide for

                                      10
<PAGE>

the acceptance of appointment hereunder of a Warrant Agent other than U.S.
Bank Trust National Association.

          (a) Without limiting the generality of the foregoing, the Call
Warrants may also be modified or amended from time to time by the Depositor,
the Trustee and the Warrant Agent with the consent of Warrant Holders of
66-2/3% of each of the Call Warrants related to the Class A-1 Certificates and
the Call Warrants related to the Class A-2 Certificates, upon receipt of an
opinion of counsel satisfactory to the Warrant Agent that the provisions
hereof (including, without limitation, the following proviso) have seen
satisfied, for the purpose of adding any provisions to or changing in any
manner or eliminating any of the provisions of the Call Warrants or of
modifying in any manner the rights of the Warrant Holders; provided, however,
that no such amendment shall (i) adversely affect in any material respect the
interests of holders of Certificates without the consent of the holders of
Certificates evidencing not less than the Required Percentage-Amendment of the
aggregate Voting Rights of such affected Certificates (as such terms are
defined in the Trust Agreement) and without written confirmation from the
Rating Agencies that such amendment will not result in a downgrading or
withdrawal of its rating of the Certificates; (ii) alter the terms on which
Call Warrants are exercisable or the amounts payable upon exercise of a
Warrant without the consent of the holders of Certificates evidencing not less
than 100% of the aggregate Voting Rights of such affected Certificates and
100% of the affected Warrant Holders or (iii) reduce the percentage of
aggregate Voting Rights required by (i) or (ii) without the consent of the
holders of all such affected Certificates. Notwithstanding any other provision
of this Warrant, this Section 6.4(b) shall not be amended without the consent
of 100% of the affected Warrant Holders.

          (b) Promptly after the execution of any such amendment or
modification, the Warrant Agent shall furnish a copy of such amendment or
modification to each Warrant Holder, to the Trustee and to the Rating
Agencies. It shall not be necessary for the consent of Warrant Holders or
holders of Certificates under this Section to approve the particular form of
any proposed amendment, but it shall be sufficient if such consent shall
approve the substance thereof. The manner of obtaining such consents and of
evidencing the authorization of the execution thereof shall be subject to such
reasonable regulations as the Warrant Agent may prescribe.

     Section 6.5 Expiration. The right to exercise the Call Warrants shall
expire on the earliest to occur of (a) the cancellation thereof, (b) the
termination of the Trust Agreement, or (c) the liquidation, disposition, or
maturity of all of the Underlying Securities.

     Section 6.6 Descriptive Headings. The headings in this Warrant Agent
Agreement are for purposes of reference only and shall not limit or otherwise
affect the meaning hereof.

     Section 6.7 GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE
LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF
LAWS.

     Section 6.8 Judicial Proceedings; Waiver of Jury. Any judicial proceeding
brought against the Trust, the Trustee or the Warrant Agent with respect to
this Warrant Agent

                                      11

Agreement may be brought in any court of competent jurisdiction in the County
of New York, State of New York or of the United States of America for the
Southern District of New York and, by execution and delivery of the Call

and any related appellate court, and irrevocably agree that the Trust, the
Trustee and the Warrant Agent shall be bound by any judgment rendered thereby
in connection with this Warrant Agent Agreement or the Call Warrants, subject
to any rights of appeal, and (b) irrevocably waive any objection that the
Trust, the Trustee or the Warrant Agent may now or hereafter have as to the
venue of any such suit, action or proceeding brought in such a court or that
such court is an inconvenient forum.

Holder by its acceptance thereof, and (ii) the Warrant Agent agrees, that it
shall not (and, in the case of the Warrant Holder, that it shall not direct
the Warrant Agent to), until the date which is one year and one day after the
payment in full of the Certificates and all other securities issued by the
Trust, the Depositor or entities formed, established or settled by the
Depositor, acquiesce, petition or otherwise invoke or cause the Trust, the
Depositor, or any such other entity to invoke the process of the United States

                                                    Dated:  ____________, 2002

Ladies and Gentlemen:

   In connection with its proposed purchase of Call Warrants (the "Call
Warrants") more particularly described in Schedule A hereto, the undersigned
purchaser (the "Purchaser") confirms that:

1.   The Purchaser understands that substantial risks are involved in an
     investment in the Call Warrants. The Purchaser represents that in making
     its investment decision to acquire the Call Warrants, the Purchaser has
     not relied on representations, warranties, opinions, projections,
     financial or other information or analysis, if any, supplied to it by any
     person, including you, Lehman ABS Corporation, as depositor (the
     "Depositor"), or U.S. Bank Trust National Association, as trustee (the
     "Trustee"), or any of your or their affiliates, except as expressly
     contained in written information, if any. The Purchaser has such
     knowledge and experience in financial and business matters as to be
     capable of evaluating the merits and risks of an investment in the Call
     Warrants, and the Purchaser is able to bear the substantial economic
     risks of such an investment. The Purchaser has relied upon its own tax,
     legal and financial advisors in connection with its decision to purchase
     the Call Warrants.

2.   The Purchaser (A) is a "Qualified Institutional Buyer" (as defined in
     Rule 144A under the Securities Act of 1933, as amended (the "1933 Act"))
     and (B) is acquiring the Call Warrants for its own account or for the
     account of an investor of the type described in clause (A) above as to
     each of which the Purchaser exercises sole investment discretion. The
     Purchaser is purchasing the Call Warrants for investment purposes and not
     with a view to, or for, the offer or sale in connection with, a public
     distribution or in any other manner that would violate the 1933 Act or
     the securities or blue sky laws of any state.

3.   The Purchaser understands that the Call Warrants have not been and will
     not be registered under the 1933 Act or under the securities or blue sky
     laws of any state, and that (i) if it decides to resell, pledge or
     otherwise transfer any Call Warrant, such Call

<PAGE>

     Warrant may be resold, pledged or transferred without registration only
     to an entity that has delivered to the Depositor and the Trustee a
     certification that it is a Qualified Institutional Buyer that purchases
     (1) for its own account or (2) for the account of such a Qualified
     Institutional Buyer, that is, in either case, aware that the resale,
     pledge or transfer is being made in reliance on said Rule 144A and (ii)
     it will, and each subsequent holder will be required to, notify any
     purchaser of any Call Warrant from it of the resale restrictions referred
     to in clause (i) above.

4.   The Purchaser understands that each of the Call Warrants will bear a
     legend substantially to the following effect, unless otherwise agreed by
     the Depositor and the Trustee:

          "THIS CALL WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT
          OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE
          DISPOSED OF EXCEPT WHILE A REGISTRATION UNDER SUCH ACT IS IN EFFECT
          OR PURSUANT TO AN EXEMPTION THEREFROM UNDER SUCH ACT. THE CALL
          WARRANT REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN COMPLIANCE
          WITH THE CONDITIONS SPECIFIED HEREIN OR IN THE SERIES SUPPLEMENT."

5.   The Purchaser understands that no subsequent transfer of the Call
     Warrants is permitted unless (A) such transfer is of a Call Warrant with
     the applicable minimum denomination and (B) the Purchaser causes the
     proposed transferee to provide to the Depositor and the Trustee such
     documentation as may be required pursuant to Section 3.2 of the Warrant
     Agent Agreement, including, if required, a letter substantially in the
     form hereof, or such other written statement as the Depositor shall
     reasonably prescribe.

6.   The Purchaser is a person or entity (a "Person") who is either

     A.   (1) a citizen or resident of the United States, (2) a corporation,
          partnership or other entity organized in or under the laws of the
          United States or any political subdivision thereof, or (3) an estate
          the income of which is includible in gross income for federal income
          tax purposes regardless of source, or (4) a trust if a court within
          the United States is able to exercise primary supervision of the
          administration of the trust and one or more United States persons
          have the authority to control all substantial decisions of the
          trust, or

     B.   a Person not described in (A), whose ownership of such Call Warrant
          is effectively connected with such Person's conduct of a trade or
          business within the United States within the meaning of the Internal
          Revenue Code of 1986, as amended (the "Code"), and its ownership of
          any interest in such Call Warrant will not result in any withholding
          obligation with respect to any payments with respect to the Call
          Warrants by any Person (other than withholding, if any, under
          Section 1446 of the Code), or

<PAGE>

     C.   a Person not described in (A) or (B) above, who is not a Person: (1)
          that owns, directly or indirectly, 10% or more of the total combined
          voting power of all classes of stock in the Underlying Securities
          Issuer (as defined in the Prospectus Supplement) entitled to vote,
          (2) that is a controlled foreign corporation related to the
          Underlying Securities Issuer within the meaning of Section 864(d)(4)
          of the Code, or (3) that is a bank extending credit pursuant to a
          loan agreement entered into in the ordinary course of its trade or
          business.

     The Purchaser agrees that (I) if it is a Person described in clause (A)
     above, it will furnish to the Depositor and the Trustee a properly
     executed IRS Form W-9, and (II) if it is a Person described in clause (B)
     above, it will furnish to the Depositor and the Trustee a properly
     executed IRS Form W-8ECI, and (III) if it is a Person described in clause
     (C) above, it will furnish to the Depositor and the Trustee a properly
     executed IRS Form W-8BEN (or, if the Purchaser is treated as a
     partnership for federal income tax purposes, a properly executed IRS Form
     W-8IMY with appropriate certification for all partners or members
     attached). The Purchaser also agrees that it will provide a new IRS form
     upon the expiration or obsolescence of any previously delivered form, and
     that it will provide such other certifications, representations or
     Opinions of Counsel as may be requested by the Depositor and the Trustee.

7.   The Purchaser agrees that if at some time in the future it wishes to
     transfer or exchange any of the Call Warrants, it will not transfer or
     exchange any of the Call Warrants unless such transfer or exchange is in
     accordance with the terms of the Warrant Agent Agreement, Series
     Supplement and other documents applicable to the Call Warrant. The
     Purchaser understands that any purported transfer of the Call Warrants
     (or any interest therein) in contravention of any of the restrictions and
     conditions in the agreements, as applicable, shall be void, and the
     purported transferee in such transfer shall not be recognized by any
     Person as a holder of such Call Warrants, for any purpose.
