by and among NORTEL NETWORKS INC., a Delaware corporation (the Parent), PS MERGER SUB,
INC., a Delaware corporation and a wholly owned subsidiary of Parent (the Purchaser), and
PEC SOLUTIONS, INC., a Delaware corporation (the Company). WHEREAS, the respective Boards of Directors of Parent, Purchaser and the Company have
determined that it would be advisable and in the best interests of their respective stockholders
for Parent to acquire the Company upon the terms and subject to the conditions set forth in this
Agreement; WHEREAS, in furtherance of such acquisition, Purchaser will make a cash tender offer (as it
may be amended from time to time as permitted under this Agreement, the Offer) to
purchase all of the issued and outstanding shares of common stock, $0.01 par value per share (the
Company Common Stock), of the Company, at a price of $15.50 per share of Company Common
Stock, net to the seller in cash, without interest thereon, upon the terms and subject to the
conditions set forth in this Agreement; WHEREAS, to effectuate such acquisition, following consummation of the Offer, Purchaser will
be merged with and into the Company, with the Company continuing as the surviving corporation in
such merger (the Merger); WHEREAS, in connection with such acquisition, Parent and Purchaser have entered into certain
agreements, dated as of the date hereof (collectively, the Stockholder Agreements) with
certain of the stockholders of the Company identified therein (collectively, the Principal
Stockholders) in respect of (x) shares of Company Common Stock beneficially owned by such
Principal Stockholders; and (y) the treatment of certain proceeds of the Offer and/or the Merger
payable to such Principal Stockholders; and WHEREAS, the Board of Directors of the Company has (i) determined that the Offer and the
Merger are fair to, and in the best interest of, the Company and its stockholders; (ii) declared
the advisability of and approved this Agreement and the Stockholder Agreements and the transactions
contemplated hereby and thereby, including the Offer and the Merger, in accordance with the General
Corporation Law of the State of Delaware (the DGCL); and (iii) resolved to recommend that
the holders of the shares of Company Common Stock accept the Offer and adopt this Agreement; NOW, THEREFORE, in consideration of the foregoing and the respective representations,
warranties, covenants and agreements set forth herein, Parent, Purchaser and the Company agree as
follows: 1

##### 



ARTICLE I THE CASH TENDER OFFER 1.1 The Offer. (a) Commencement of the Offer; Acceptance of Shares. Provided that this Agreement
shall not have been terminated in accordance with Section 9.1, subject to the terms and
conditions of this Agreement, as soon as reasonably practicable after the date of public
announcement of the execution of this Agreement (but in any event not later than twenty (20)
Business Days after the date of such public announcement), Purchaser shall commence (within the
meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the
rules and regulations thereunder, the Exchange Act)), the Offer to purchase any and all
outstanding shares of Company Common Stock at a price of $15.50 per share, net to the seller in
cash, without interest thereon (such amount, or any greater amount per share paid pursuant to the
Offer, the Offer Consideration). On the terms and subject to the prior satisfaction or
waiver of the conditions of the Offer and this Agreement, Purchaser shall accept for payment all
shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer as soon as
legally permitted to do so under applicable Law after the expiration of the Offer, and shall pay
for all such shares promptly after acceptance and in any event in compliance with the obligations
respecting prompt payment pursuant to Rule 14e-1(c) under the Exchange Act. For purposes of this
Agreement, Law means any federal, state, local or foreign statute, law, ordinance, rule,
administrative interpretation, executive order, regulation or other requirement of any Governmental
Entity. The obligation of Purchaser to accept for payment and pay for shares of Company Common
Stock validly tendered in the Offer and not withdrawn shall be subject to the condition that there
shall be validly tendered and not withdrawn immediately prior to the expiration of the Offer such
number of shares of Company Common Stock that would constitute at least a majority of the shares of
Company Common Stock that in the aggregate are outstanding determined on a Fully Diluted Basis on
the date of the expiration of the Offer (the Minimum Condition) and to the other
conditions set forth in Annex I to this Agreement. The Company agrees that no shares of
Company Common Stock held by the Company or any of its Subsidiaries will be tendered in the Offer.
For purposes of this Agreement, Fully Diluted Basis means, as of any applicable date,
without duplication, the number of shares of Company Common Stock outstanding together with the
shares of Company Common Stock which the Company may be required to issue pursuant to obligations
outstanding under the Company Stock Plans, the ESPP or similar benefit plans, the conversion or
exchange of all outstanding securities convertible or exchangeable into, shares of Company Common
Stock, or otherwise, in each case whether or not vested, exerciseable, exercised or converted at
the time of determination. (b) Expiration Date; Extensions and Amendments; Subsequent Offering Period. The
initial expiration date of the Offer shall be the twentieth (20th) Business Day after
commencement of the Offer (determined in accordance with Rules 14d-1(g)(3) and 14d-2 under the
Exchange Act). As used in this Agreement, the term Business Day shall have the meaning
set forth in Rule 14d-1(g)(3) promulgated under the Exchange Act. Purchaser expressly reserves the
right, subject to compliance with the Exchange Act, to waive, amend or modify any term or condition
of the Offer in its sole discretion; provided, however, that, without the prior
consent of the Company, Purchaser shall not (and Parent shall not cause or permit Purchaser to):
(i) waive 2

the Minimum Condition; (ii) change the form of consideration payable in the Offer, decrease
the Offer Consideration or decrease the number of shares of Company Common Stock sought pursuant to
the Offer; (iii) amend any material term of the Offer in any manner adverse to holders of shares of
Company Common Stock; (iv) impose any condition to the Offer not set forth in Annex I; or
(v) extend the expiration date of the Offer; provided, however, that, without the
consent of the Company, Purchaser may extend the expiration date of the Offer (A) as required by
applicable Law (including for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the SEC) or the staff thereof), (B)
if, immediately prior to the scheduled expiration date of the Offer (as it may be extended) and
prior to acceptance for payment by Purchaser of any shares of Company Common Stock pursuant to the
Offer, any condition to the Offer has not been satisfied or waived, Purchaser may, in its sole
discretion, extend the expiration date of the Offer for one or more periods (not in excess of five
(5) Business Days each), (C) if, immediately prior to the scheduled expiration date of the Offer
(as it may be extended), the shares of Company Common Stock validly tendered and not properly
withdrawn pursuant to the Offer constitute at least the Minimum Condition but less than 90% of the
outstanding shares of Company Common Stock, Purchaser may, in its sole discretion, extend the Offer
for one or more periods not to exceed an aggregate of ten (10) Business Days, notwithstanding that
all conditions to the Offer are satisfied as of such expiration date of the Offer, (D) in
connection with an increase in the consideration to be paid pursuant to the Offer so as to comply
with applicable rules and regulations of the SEC, or (E) in Purchasers sole discretion, for any
other reason for one or more periods not to exceed an aggregate of five (5) Business Days.
Purchaser may, without the consent of the Company, elect to provide a subsequent offering period
for the Offer in accordance with Rule 14d-11 of the Exchange Act following its acceptance for
payment of shares of Company Common Stock in the Offer. If, as of the initial expiration date of
the Offer or any expiration date of the Offer within fifteen (15) Business Days of the initial
expiration date of the Offer, the HSR Condition, the Exon-Florio Condition or the DSS Condition, in
each case, as set forth in Annex I, have not been satisfied or waived but are reasonably
capable of being satisfied within fifteen (15) Business Days of the initial expiration date of the
Offer, and if all other conditions set forth in Annex I are satisfied or are reasonably
capable of being satisfied on such expiration date, then, upon the written request of the Company,
provided the Company is in full compliance with its obligations hereunder and the Principal
Stockholders are in full compliance with their obligations pursuant to the Stockholder Agreements,
Parent agrees to cause Purchaser to extend the expiration date of the Offer for one or more periods
not to exceed an aggregate of fifteen (15) Business Days from the initial expiration date of the
Offer. (c) Schedule TO and Offer Documents. On the date of commencement of the Offer, Parent
and Purchaser shall file with the SEC a Tender Offer Statement on Schedule TO (together with all
amendments and supplements thereto, the Schedule TO) with respect to the Offer. The
Schedule TO shall contain an offer to purchase (the Offer to Purchase), a form of the
related letter of transmittal (the Letter of Transmittal), a form of notice of guaranteed
delivery, and ancillary documents and instruments pursuant to which the Offer will be made
(collectively, together with any supplements or amendments thereto, the Offer Documents).
Parent and Purchaser agree that the Offer Documents shall comply in all material respects with the
requirements of applicable U.S. federal securities Laws and, on the date first filed with the SEC
and on the date first published, sent or given to the Companys stockholders, shall not contain any
untrue statement of a material fact or omit to state any material fact required to be 3

stated therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that no representation or warranty
is made by Parent or Purchaser with respect to information supplied by the Company or any of its
stockholders in writing for inclusion or incorporation by reference in the Offer Documents. Parent
and Purchaser shall take all steps necessary to cause the Offer Documents to be disseminated to
holders of shares of Company Common Stock, as and to the extent required by applicable U.S. federal
securities Laws. Parent, Purchaser and the Company each shall promptly correct any information
provided by it for use in the Schedule TO or the Offer Documents if and to the extent that such
information shall have become false or misleading in any material respect; and Parent and Purchaser
shall take all steps necessary to amend or supplement the Schedule TO and, as applicable, the Offer
Documents and to cause the Schedule TO as so amended and supplemented to be filed with the SEC, as
and to the extent required by applicable U.S. federal securities Laws. The Company and its counsel
shall be given reasonable and adequate opportunity to review and comment upon the Offer Documents
and any amendments thereto sufficiently in advance of the filing thereof with the SEC or
dissemination to the Companys stockholders. Parent and Purchaser shall provide the Company and
its counsel with a copy of any written comments or telephonic notification of any oral comments
Parent, Purchaser or their counsel may receive from the SEC or its staff with respect to the Offer
promptly after the receipt thereof, shall consult with the Company and its counsel prior to
responding to any such comments, and shall provide the Company and its counsel with a copy of any
written responses thereto and telephonic notification of any oral responses thereto of Parent or
Purchaser or their counsel. (d) Provisions of Funds by Parent. Parent shall provide or cause to be provided to
Purchaser on a timely basis the funds necessary to accept for payment and pay for any and all
shares of Company Common Stock that Purchaser becomes obligated to purchase pursuant to the Offer. (e) Tax Withholding. Purchaser shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to the Offer such amounts as Purchaser reasonably
determines that it is required to deduct and withhold with respect to the making of such payment
under the Internal Revenue Code of 1986, as amended (the Code), or under any other
applicable Law. If and to the extent that amounts so withheld are not paid to a taxing authority,
such amounts shall be tendered to the holder of the shares of Company Common Stock in respect of
which such deduction and withholding were made by Purchaser. 1.2 Company Actions. (a) The Company hereby approves of and consents to the Offer and the Merger and represents and

in the Companys 2004 proxy statement has advised the Company that his or her current

pursuant to the Offer. (e) Stockholder Lists. In connection with the Offer, the Company shall promptly
furnish (or cause its transfer agent or agents to furnish) to Purchaser or its designated agent
lists and mailing labels containing the names and addresses of (i) the record holders of the shares
of Company Common Stock as of a recent date, (ii) those persons becoming record holders subsequent
to such date and updated on a daily basis, (iii) the beneficial owners of the shares of Company
Common Stock as of a recent date, and (iv) those persons becoming beneficial owners of the shares
of Company Common Stock subsequent to such date and updated on a daily basis, together with copies
of all security position listings and all other computer files and other information in the
Companys possession or control regarding the record holders and beneficial owners of the shares of
Company Common Stock, and shall furnish to Purchaser such information and assistance (including
updated mailing labels, lists and information) as it may request for the purpose of communicating
the Offer to the Companys stockholders. From and after the date of this Agreement, all such
information concerning the Companys record and beneficial holders shall be made available promptly
to Purchaser. For purposes of this Agreement, Person means an individual, corporation,
partnership, limited partnership, limited liability company, syndicate, person (including a
person as defined in Section 13(d)(3) of the Exchange Act), trust, association or entity or
government, political subdivision, agency or instrumentality of a government. Subject to the
requirements of applicable Law and, except for such actions necessary to disseminate the Offer
Documents and any other documents necessary to consummate the Offer and the Merger and the other
transactions contemplated hereby, Parent and Purchaser shall, and shall use their reasonable
efforts to cause their respective Representatives to, hold in confidence the information contained
in such labels and lists, to use such information only in connection with the Offer and the Merger
and, if this Agreement is terminated in accordance with Section 9.1, upon written request
of the Company, to deliver promptly to the Company all copies of such information then in their
possession and under their control. 1.3 Directors. (a) Promptly after the acceptance for payment of shares of Company Common Stock tendered
pursuant to the Offer representing at least a majority of the outstanding shares of Company Common
Stock on a Fully Diluted Basis (the Appointment Time) and, from time to time thereafter,
as shares of Company Common Stock are accepted for payment by Parent or Purchaser, Purchaser shall
be entitled to designate such number of members of the Company Board (the Purchaser
Designees), rounded up to the nearest whole number, as will give Purchaser representation on
the Company Board equal to the product of the total number of members of the Company Board (after
giving effect to any increase in the number of the directors elected pursuant to this sentence)
multiplied by the percentage that the number of shares of Company Common Stock beneficially owned
by Parent or Purchaser at such time (including shares of Company Common Stock so accepted for
payment) bears to the total number of shares of Company Common Stock then outstanding;
provided, however, that in no event shall Purchaser Designees constitute less than
a majority of the Company Board. In furtherance thereof, the Company shall, upon the request of,
and as specified by, Purchaser, 6

##### 



promptly (and in any event within one (1) Business Day) either increase the size of the
Company Board or secure the resignations of such number of the Companys incumbent directors, or
both, as is necessary to enable Purchaser Designees to be so elected or appointed to the Company
Board and the Company shall take all actions available to the Company to cause Purchaser Designees
to be so elected or appointed. At such time, if requested by Purchaser, the Company shall also
take all action necessary to cause persons designated by Purchaser to constitute at least the same
percentage (rounded up to the next whole number) as is on the Company Board of (i) each committee
of the Company Board, (ii) each board of directors (or similar body) of each Subsidiary of the
Company and (iii) each committee (or similar body) of each such board, in each case only to the
extent permitted by applicable Law or the rules of any stock exchange or trading market on which
the Company Common Stock is listed and traded. The provisions of this Section 1.3 are in
addition to and shall not limit any rights which Purchaser, Parent or any of their affiliates (as
such term is defined in Rule 405 promulgated under the Securities Act of 1933, as amended (the
Securities Act)) (Affiliates) may have as a holder or beneficial owner of
shares of Company Common Stock as a matter of applicable Law with respect to the election of
directors or otherwise. (b) Compliance with Section 14(f) and Rule 14f-1. The Company shall take all actions
required in order to fulfill its obligations under Section 1.3(a), including mailing to its
stockholders the information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder as part of the Schedule 14D-9; provided, however, that
Parent and Purchaser shall supply to the Company in writing prior to the filing with the SEC of the
Schedule 14D-9 any information with respect to Parent and Purchaser and Purchaser Designees to the
extent required by such Section 14(f) and Rule 14f-1. (c) Continuing Directors. Notwithstanding the provisions of this Section 1.3,
the parties hereto shall use their respective reasonable best efforts to ensure that at least two
(2) of the members of the Company Board shall, at all times following the Appointment Time and
prior to the Effective Time (as defined in Section 2.3), be directors of the Company who
were directors of the Company on the date hereof (the Continuing Directors);
provided, however, that, if there shall be in office less than two Continuing
Directors for any reason, the Company Board shall cause the person designated by the remaining
Continuing Director to designate a person to fill such vacancy and such person shall be deemed to
be an Continuing Director for all purposes of this Agreement, or if no Continuing Directors then
remain, the other directors of the Company then in office shall designate two persons to fill such
vacancies who will not be directors, officers, employees or Affiliates of Parent or Purchaser and
such persons shall be deemed to be Continuing Directors for all purposes of this Agreement. From
and after the time, if any, that Purchaser Designees constitute a majority of the Company Board and
prior to the Effective Time, subject to the terms hereof, any amendment or modification of this
Agreement, any termination of this Agreement by the Company, any extension of time for performance
of any of the obligations of Parent or Purchaser hereunder, and any waiver of any condition to the
Companys obligations hereunder or any of the Companys rights hereunder may be effected only if
(in addition to the approval of the Company Board as a whole) there are in office one or more
Continuing Directors and such action is approved by at least one of the Continuing Directors then
in office. Following the Appointment Time and prior to the Effective Time, neither Parent nor
Purchaser shall take any other action to remove any Continuing Director absent cause. 7

of State of the State of Delaware. The Merger shall become effective upon the filing of the
Certificate of Merger with the Secretary of State of the State of Delaware or at such subsequent
time or date as Parent and the Company shall agree and specify in the Certificate of Merger. The

Time, the Company shall cause each member of
the Company Board, other than Purchaser Designees, to execute and deliver a letter effectuating his
or her resignation as a director of the Company effective upon the Effective Time. ARTICLE III CONVERSION OF SECURITIES IN THE MERGER 3.1 Effect of Merger on Capital Stock. (a) Conversion of Securities. At the Effective Time, by virtue of the Merger and
without any action on the part of Purchaser, the Company, the Surviving Corporation or the holder
of any of the following securities: (i) each share of Company Common Stock issued and outstanding immediately prior
to the Effective Time (other than shares of Company Common Stock to be cancelled
pursuant to clause (ii) below and any Appraisal Shares (as defined in Section
3.1(b)) shall be automatically cancelled and extinguished and be converted into
and become the right to receive from the Surviving Corporation $15.50 in cash per
share (or any such higher price per share of Company Common Stock as may be paid in
the Offer) without any interest thereon (the Merger Consideration), and
all other rights of the holder thereof with respect thereto shall cease to exist; (ii) each share of Company Common Stock issued and outstanding immediately
prior to the Effective Time that is owned by Parent, Purchaser or the Company or any
direct or indirect Subsidiary of the Company, including all shares of Company Common
Stock held by the Company as treasury stock, shall automatically be cancelled, and
no payment shall be made with respect thereto; and (iii) each share of Purchasers capital stock issued and outstanding
immediately prior to the Effective Time shall be converted into and become one
validly issued, fully paid and nonassessable share of the same class of capital
stock of the Surviving Corporation. (b) Appraisal Shares. Notwithstanding anything in this Agreement to the contrary,
shares of the Company Common Stock that are issued and outstanding immediately prior to the
Effective Time and that are held by any holder who is entitled to demand and who properly demands
appraisal of such shares (the Appraisal Shares) pursuant to, and that complies in all
respects with, the provisions of Section 262 of the DGCL shall not be converted into the right to
receive the Merger Consideration as provided in Section 3.1(a)(i), but instead such holder
shall be entitled to such rights (but only such rights) as are granted by Section 262 of the DGCL.
At the Effective Time, all Appraisal Shares shall no longer be outstanding and automatically shall
be cancelled and shall cease to exist, and, except as otherwise provided by applicable Law, each
holder of Appraisal Shares shall cease to have any rights with respect to the
Appraisal Shares, other than such rights as are granted by Section 262 of the DGCL. 9

##### 



Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive,
withdraw or lose the right to appraisal under Section 262 of the DGCL or a court of competent
jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262
of the DGCL, then the right of such holder to be paid the appraised value of such holders
Appraisal Shares under Section 262 of the DGCL shall cease and such Appraisal Shares shall be
deemed to have been converted at the Effective Time into, and shall have become, the right to
receive the Merger Consideration as provided in Section 3.1(a)(i) without interest. The
Company shall give Parent and Purchaser prompt notice of any demands for appraisal, or notices of
intent to demand appraisal, received by the Company with respect to shares of Company Common Stock,
and Parent and Purchaser shall have the right to participate in and direct all negotiations and
proceedings with respect to such demands. Prior to the Effective Time, the Company shall not,
except with the prior written consent of Parent and Purchaser, make any payment with respect to, or
settle, or offer to settle, any such demands, or agree to do any of the foregoing. 3.2 Exchange of Certificates. (a) Paying Agent. Prior to the Effective Time, Parent shall select a bank or trust
company (or such other Person as shall be reasonably acceptable to the Company) to act as agent
(the Paying Agent) for the payment after the Effective Time of the Merger Consideration
upon surrender of stock certificates that immediately prior to the Effective Time represented
outstanding shares of Company Common Stock that were converted into the right to receive Merger
Consideration pursuant to Section 3.1(a)(i) (each, a Certificate). From time to
time after the Effective Time, Parent shall provide, or cause the Surviving Corporation to provide,
to the Paying Agent, on a timely basis as and when needed, cash necessary for payment of the Merger
Consideration pursuant to Section 3.1(a)(i) upon surrender of Certificates (such cash being
hereinafter referred to as the Exchange Fund). (b) Exchange Procedure. As soon as reasonably practicable after the Effective Time,
but in any event, not later than the fifth (5th) Business Day following the Effective
Time, the Paying Agent shall mail to each holder of record of a Certificate (i) a Letter of
Transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the
Certificate shall pass, only upon delivery of the Certificate to the Paying Agent and shall be in
such form and have such other provisions as Parent may reasonably specify) and (ii) instructions
for use in effecting the surrender of the Certificate in exchange for the Merger Consideration.
Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or
agents as may be appointed by Parent, together with such Letter of Transmittal, duly completed and
properly executed, and such other documents as may reasonably be required by the Paying Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash
into which the shares of Company Common Stock formerly represented by such Certificate shall have
been converted pursuant to Section 3.1(a)(i) into the right to receive, and the Certificate
so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company
Common Stock that is not registered in the stock transfer records of the Company, payment may be
made to a Person other than the Person in whose name the Certificate so surrendered is registered
if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the
Person requesting such payment shall pay any transfer or other taxes
required by reason of the payment to a Person other than the registered holder of such
Certificate 10

##### 



or establish to the satisfaction of Parent that such tax has been paid or is not
applicable. Until surrendered as contemplated by this Section 3.2, each Certificate shall
be deemed at any time after the Effective Time to represent only the right to receive upon such
surrender the amount of cash, without interest, into which the shares of Company Common Stock
formerly represented by such Certificate have been converted pursuant to Section 3.1(a).
No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate. (c) No Further Ownership Rights in Company Capital Stock. The Merger Consideration
paid upon the surrender of a Certificate in accordance with the terms of this Article III
shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of
Company Common Stock formerly represented by such Certificate. Upon the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further registration of
transfers on the stock transfer books of the Surviving Corporation of shares of Company Common
Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time,
any Certificates are presented to the Surviving Corporation or the Paying Agent for any reason,
they shall be canceled and exchanged as provided for in this Article III. (d) Termination of Exchange Fund. Any portion of the Exchange Fund that remains
undistributed to the holders of Certificates for six (6) months after the Effective Time shall be
delivered by the Paying Agent to Parent, upon demand, and any holder of a Certificate who has not
theretofore complied with this Article III shall thereafter look only to Parent for payment
of the Merger Consideration, but shall have no greater rights against Parent than may be accorded
to general unsecured creditors of Parent under applicable Law. (e) No Liability. None of Parent, its Affiliates, Purchaser, the Company, the
Surviving Corporation or the Paying Agent or their respective Representatives (as defined in
Section 6.2) shall be liable to any Person in respect of any cash delivered to a public
official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate
has not been surrendered prior to five (5) years after the Effective Time (or immediately prior to
such earlier date on which the Merger Consideration in respect of such Certificate would otherwise
escheat to or become the property of any Governmental Entity), any such cash in respect of such
Certificate shall, to the extent permitted by applicable Law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any Person previously entitled thereto. (f) Investment of Exchange Fund. The Paying Agent shall invest any cash included in
the Exchange Fund as directed by Parent. Any interest and other income resulting from such
investments shall be paid to Parent. (g) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed,
the Paying Agent shall pay to such holder the Merger Consideration required pursuant to Section
3.1(a)(i) in exchange for such lost, stolen or destroyed Certificate, upon the making of an
affidavit of that fact by the holder thereof with such assurances as Parent, in its discretion and
as a condition precedent to the payment of the Merger Consideration, may require of the holder of
such lost, stolen or destroyed Certificate, and upon posting by such holder of a bond, in such
reasonable amount as Parent may direct as indemnity against any claim in respect thereof. 11

##### 



(h) Withholding Rights. Parent, the Surviving Corporation and the Paying Agent shall
be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this
Agreement such amounts as it reasonably determines that it is required to deduct and withhold with
respect to the making of such payment under the Code or any other applicable Law. To the extent
that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the
Surviving Corporation or the Paying Agent, such withheld amounts shall be treated for all purposes
of this Agreement as having been paid to the holder of the shares of Company Common Stock in
respect of which such deduction and withholding was made by Parent, the Surviving Corporation or
the Paying Agent. If and to the extent that amounts so withheld are not paid to a taxing
authority, such amount shall be tendered to the former holder of the shares of Company Common Stock
in respect of which such deduction and withholding were made by Purchaser. 3.3 Company Stock Options; ESPP (a) Payment for Company Stock Options. As soon as practicable following the date of
this Agreement, the Company Board (or, if appropriate, any committee administering the Company
Stock Plans) shall adopt such resolutions or take such other actions as are required to adjust the
terms of all outstanding Company Stock Options heretofore granted under any Company Stock Plan to
provide as follows: (i) except as expressly provided hereby, the outstanding Company Stock Options
shall not be altered or modified as a consequence of this Agreement, the Offer or the Merger or the
other transactions contemplated hereby, and the applicable vesting periods shall not be shortened,
waived or otherwise accelerated in any way (it being understood and agreed that this provision
shall not prohibit any automatic, non-discretionary acceleration of vesting pursuant to the terms
of the Companys Key Executive Severance Plan and agreements issued in connection therewith that
are signed and in effect on the date of this Agreement and are listed in attachment 2 of
Section 4.14(h) of the Company Disclosure Schedule); (ii) at the Effective Time, each
outstanding Company Stock Option shall be cancelled and converted into the right, subject to
vesting requirements where applicable, to a cash payment from the Company as follows: (A) in the
case of an outstanding Company Stock Option that is vested at the Effective Time, the holder of
such vested Company Stock Option shall at the Effective Time receive a payment of an amount equal
to (i) the excess, if any, of (x) the Merger Consideration per share of Company Common Stock over
(y) the exercise price per share of Company Common Stock subject to such Company Stock Option,
multiplied by (ii) the number of shares of Company Common Stock for which such Company Stock Option
is then exercisable and not theretofore exercised; and (B) in the case of an outstanding Company
Stock Option that is unvested at the Effective Time, if and only to the extent the holder satisfies
the vesting requirements in accordance with the terms of the applicable Company Stock Option
existing as of the date hereof, the holder of such unvested Company Stock Option shall become
entitled to a payment calculated as set forth in Section 3.3(a)(ii)(A), above, on such
date(s) as the right to exercise vests in accordance with the terms of the applicable Company Stock
Option; and (iii) notwithstanding the foregoing, each Company Stock Option with an exercise price
equal to or greater than the Merger Consideration shall be automatically cancelled and cease to
exist at the Effective Time without further action on the part of the Company or the holder of such
Company Stock Option. The Company shall use its best efforts to obtain all consents of the holders
of the Company Stock Options as shall be necessary to effectuate the foregoing.
Notwithstanding anything to the contrary contained in this Agreement, payment shall, at
Parents 12

##### 



request, be withheld in respect of any Company Stock Option until all necessary consents
are obtained with respect to any Company Stock Option requiring any such consent. (b) Withholding. All amounts payable pursuant to this Section 3.3 shall be
subject to any required withholding of Taxes and shall be paid without interest. (c) Termination of Company Stock Plans. The Company Stock Plans shall terminate as of
the Effective Time, and the provisions in any other Company Employee Plan providing for the
issuance, transfer or grant of any capital stock of the Company or any interest in respect of any
capital stock of the Company shall terminate and be deleted as of the Effective Time or (if
permissible) at Purchasers request, upon the initial acceptance of the shares of Company Common
Stock pursuant to the Offer, and the Company shall ensure that following the Effective Time no
holder of a Company Stock Option or any participant in any Company Stock Plan or other Company
Employee Plan shall have any right thereunder to acquire any capital stock of the Company or the
Surviving Corporation. (d) Employee Stock Purchase Plan. As soon as practicable following the date of this
Agreement, the Company Board shall adopt such resolutions or take such actions as are required
under applicable Law and the Companys Employee Stock Purchase Plan (ESPP) to: (i) immediately
suspend any right to increase contributions into the ESPP and freeze contribution rates currently
in effect; (ii) suspend all further contributions to the ESPP as of April 23, 2005 (the
Suspension Date); (iii) designate and treat the second (2nd) Business Day following the
Suspension Date as the last day of the Option Period (as such term is defined in the ESPP) now in
progress under the ESPP; (iv) in accordance with the ESPP, provide that the Option Price (as such
term is defined in the ESPP) for the current Option Period for employees whose contributions to the
ESPP (A) commenced as of January 1, 2005 shall be $11.98 (the January ESPP Price))
and (B) commenced as of April 1, 2005 shall be $10.82 (the April ESPP Price and, together
with the January ESPP Price, the ESPP Price) which, in each case, is equal to 85% of the
average of the high and low sales prices of the Company Common Stock of the applicable first day of
the current Option Period; (v) suspend commencement of any new Option Periods under the ESPP; (vi)
assure that all amounts contributed by each participant under the ESPP and not theretofore
withdrawn are converted pursuant to the ESPP immediately prior to the Effective Time into the right
to receive an amount in cash equal to the product of (A) the per share Merger Consideration, multiplied by (B) such participants ESPP Number (as defined below); and
(vii) terminate the ESPP at the Effective Time. With respect to each ESPP participant, the
ESPP Number shall mean the quotient (rounded to the nearest tenth) of (x) the amount of
their total contributions to the ESPP as of the Suspension Date less any amount withdrawn therefrom
prior to the Effective Time divided by (y) the applicable ESPP Price. ARTICLE IV REPRESENTATIONS AND WARRANTIES OF THE COMPANY Except as set forth in the disclosure schedule (arranged in paragraphs corresponding to the
numbered and lettered paragraphs contained in this Article IV, and the disclosure in any
paragraph shall qualify only such specifically enumerated paragraph) delivered by the Company 13

For purposes of this Agreement, Building means Building VII Associates L.C., a limited

outside and in-house
counsel with respect to, and are familiar with, the requirements of the Sarbanes-Oxley Act. The
Company and its Subsidiaries are, and have been, in compliance with the applicable provisions of

financial officer of the Company has made all certifications required by Rule 13a-14 or 15d-14
under the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act with respect to the
Company SEC Reports, and the statements contained in such certifications are accurate as of the
date hereof. For purposes of this Agreement, principal executive officer and principal

special purpose or limited purpose entity or person, on the other hand or any off-balance sheet
arrangements (as defined in Item 303(a) of Regulation S-K of the SEC)). The Companys and its
Subsidiaries systems of internal controls over financial reporting are sufficient to provide
reasonable assurance (i) that transactions are recorded as necessary to permit preparation of

in accordance with the authorization of management and (iii) regarding prevention or timely
detection of the unauthorized acquisition, use or disposition of the Companys and the
Subsidiaries assets that would materially affect the Companys financial statements. No material
weakness was identified in managements assessment of internal controls as of December 31, 2004
(nor has any such material weakness since been identified). The Companys and its Subsidiaries
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange
Act) are reasonably designed to ensure that (x) all information (both financial and non-financial)
required to be disclosed by the Company in the reports that it files or submits under the Exchange
Act is recorded, processed, summarized and reported within the time periods specified in the rules
and forms of the SEC and (y) all such information is accumulated and communicated to the Companys
management as appropriate to allow timely decisions regarding required disclosure and to make the
certifications of the principal executive officer and principal financial officer of the Company
required under the Exchange Act with respect to such reports. The audit committee of the Company
Board includes an Audit Committee Financial Expert, as defined by Item 401(h)(2) of Regulation S-K.
The Company has adopted a code of ethics, as defined by Item 406(b) of Regulation S-K, applicable
to its principal executive officer, principal financial officer, principal accounting officer or

of the Companys code of ethics, and to the Companys Knowledge, there have been no violations of
the Companys code of ethics by its principal executive officer, principal financial officer,
principal accounting officer or controller, persons performing similar functions, or other senior
executive officers. (e) No Resignation. Without limiting the generality of the foregoing,
PricewaterhouseCoopers LLP has not resigned or been dismissed as independent public accountant of
the Company as a result of or in connection with any disagreement with the Company on a matter of
accounting practices which materially impacts or would require the restatement of any previously

in the ordinary course of business consistent with past practice (the Ordinary Course of
Business), neither the Company nor its Subsidiaries have incurred any liabilities, either

Effect or (b) any other action or event (other than actions or events in anticipation of or
required in connection with the transactions contemplated by this Agreement) that would have
required the consent of Parent pursuant to Section 6.1 of this Agreement had such action or
event occurred at a time when the Company was subject to such restrictions. 4.7 Agreements, Contracts and Commitments. (a) All of the Contracts required to be set forth in paragraphs (b, (c) and (e) of Section

paragraph
(vi)(E) of Annex I, or would materially impair or prevent the satisfaction of any condition
in Annex I or Article VIII. 6.2 No Solicitation. (a) Neither the Company nor any of its Subsidiaries shall, and the Company shall cause its and
their directors, officers, employees, investment bankers, attorneys, accountants or other agents,
advisors or representatives (such directors, officers, employees, investment bankers, attorneys,
accountants, other agents, advisors and representatives collectively, Representatives)
not to, directly or indirectly: (i) solicit, initiate, participate, knowingly encourage or take any
other action which may facilitate, any inquiries or the making of any proposal or offer that
constitutes, or may reasonably be expected to lead to, any Acquisition Proposal or (ii) enter into,
continue or otherwise participate in any discussions or negotiations regarding, furnish to any
Person any information with respect to, assist or participate in any effort or attempt by any
Person with respect to, or otherwise cooperate in any way with, any Acquisition Proposal.
Notwithstanding the foregoing, prior to the acceptance for payment of any shares of Company Common
Stock pursuant to the Offer (the Specified Time), in response to a Superior Proposal that
did not result from a breach of this Section 6.2 or any other provision of this Agreement,
and subject to compliance with Section 6.2(c), the Company may, to the extent required by
the fiduciary obligations of the Company Board, as determined in good faith by the Company Board
after consultation with outside counsel, (x) furnish non-public information with respect to the
Company to the Person making such Superior Proposal pursuant to a customary confidentiality
agreement not less restrictive of the other party than the Non-Disclosure Agreement and (y)
participate in discussions or negotiations with such Person regarding any Superior Proposal.
Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in
this Section 6.2(a) by any Representative of the Company or any of its Subsidiaries, shall
be deemed to be a breach of this Section 6.2(a) by the Company. (b) The Company Board shall recommend the Offer, this Agreement and the Merger to the Company
stockholders, and neither the Company Board nor any committee thereof shall (i) except as set forth
in this Section 6.2, withdraw or modify, or propose to withdraw or modify, in a manner
adverse to Parent or Purchaser, the approval or recommendation by the Company Board or any such
committee of this Agreement, the Offer or the Merger, (ii) cause or permit the Company to enter

or recommend, propose to adopt, approve or recommend, or take a neutral position with respect to,
any Acquisition Proposal or (iv) grant any approval pursuant to Section 203(a) of the DGCL.

Business Day following Parents receipt of written notice advising Parent that the Company Board
has determined that an Acquisition Proposal is a Superior Proposal, specifying the material terms
and conditions of such Superior Proposal and identifying the Person making such Superior Proposal,

Section 6.2 or any other provision of this Agreement, withdraw or modify, in a manner
adverse to Parent or Purchaser, or fail to make, the recommendation by the Company Board of this
Agreement, the Offer or the Merger, if the Company Board determines in good faith, after 49

consultation with outside counsel, that failure to do so would violate its fiduciary obligations
(such a withdrawal or modification, a Withdrawal of Recommendation). (c) The Company shall immediately advise Parent orally, with written confirmation to follow
within twenty-four (24) hours, of any Acquisition Proposal or any request for nonpublic information
in connection with any Acquisition Proposal, or any inquiry with respect to, or that could
reasonably be expected to lead to any Acquisition Proposal, the material terms and conditions of
any such Acquisition Proposal or inquiry and the identity of the Person making any such Acquisition
Proposal or inquiry, and shall promptly provide Parent with copies of any true and complete
correspondence, including draft agreements, relating to the foregoing. In the event the Company is
permitted to do so pursuant to Section 6.2(a), the Company shall nonetheless not provide
any information to or participate in discussions or negotiations with the Person making any
Superior Proposal until three (3) Business Days after the Company has first notified Parent of such
Acquisition Proposal as required by the preceding sentence. The Company shall (i) keep Parent
fully informed of the status and details (including immediate oral and written notification of any
change to the terms) of any such Acquisition Proposal or inquiry, and (ii) if Parent shall make a
counterproposal, consider and cause its financial and legal advisors to negotiate on its behalf in
good faith with respect to the terms of such counterproposal. Contemporaneously with providing any
information to any other Person in connection with any such Superior Proposal or inquiry, the
Company shall furnish a copy of such information to Parent. (d) Nothing contained in this Agreement shall be deemed to prohibit the Company from taking
and disclosing to its stockholders a position with respect to a tender or exchange offer by a third
party required pursuant to Rule 14d-9 and 14e-2(a) promulgated under the Exchange Act;
provided, however, that, except as set forth in Section 6.2(b), in no event
shall the Company Board or any committee thereof withdraw or modify, or propose to withdraw or
modify, its recommendations and approvals with respect to this Agreement, the Offer or the Merger
or adopt, approve or recommend, or propose to adopt, approve or recommend, any Acquisition
Proposal. (e) The Company shall, and shall cause its Subsidiaries and its and their Representatives to,
cease immediately all discussions and negotiations regarding any proposal that constitutes, or may
reasonably be expected to lead to, an Acquisition Proposal. The Company shall use its reasonable
best efforts to have all copies of all nonpublic information it or its Subsidiaries and its and
their Representatives have distributed on or prior to the date of this
Agreement to other potential purchasers within the past twelve months returned to the Company
or destroyed as soon as possible. (f) For purposes of this Agreement: Acquisition Proposal means any inquiry, proposal or offer by any Person other than
Parent, Purchaser or any of their respective Affiliates relating to, or that is reasonably likely
to lead to, directly or indirectly: (i) a merger, consolidation, dissolution, sale of substantial
assets, tender offer, exchange offer, joint venture, liquidation, recapitalization, share exchange,
business combination or other similar transaction involving the Company or any of its Subsidiaries,

securities of the Company or any Subsidiary equal to or greater than 15% of the number of such
shares outstanding before such acquisition or (iii) the acquisition by any Person in any manner,
directly or indirectly, of assets that constitute 15% or more of the net revenues, net income,
EBITDA or the consolidated total assets of the Company, in each case other than the transactions
contemplated by this Agreement; provided, however, that solely for purposes of
Section 9.3 hereof, the references to 15% in this definition shall be replaced by 50%. Superior Proposal means any unsolicited, bona fide written Acquisition Proposal to
acquire all or substantially all of the equity securities or assets of the Company, pursuant to a
tender or exchange offer, a merger or a sale of its assets, (i) on terms which the Company Board
determines, at a duly constituted meeting of the Company Board, in its reasonable good faith
judgment to be more favorable, both financially and otherwise, to the holders of Company Common
Stock than the transactions contemplated by this Agreement (after receiving the advice of the
Companys independent financial advisor concerning the value of the consideration provided for in
such proposal relative to the value of the consideration provided for in the Offer), taking into
account all the terms and conditions of such Acquisition Proposal (but excluding any impact on the
Principal Stockholders of the terms of any stockholders agreement or the absence thereof included
as a facet thereof) and this Agreement and the Stockholder Agreements (including any bona fide
offer or proposal by Parent to amend the terms of this Agreement and/or the Stockholder
Agreements), (ii) that in the good faith judgment of the Company Board (after consultation with
outside counsel) is reasonably capable of being completed timely on the terms proposed, taking into
account all financial, regulatory, legal and other aspects of such proposal and (iii) for which
financing, to the extent required, is then committed. 6.3 Certain Tax Matters. (a) From the date hereof until the Effective Time, the Company shall, and shall cause each of
the Subsidiaries to, (i) timely prepare and file (including pursuant to timely filed extensions),
consistent with past practice, all Tax Returns (Post-Signing Returns) required to be
filed, (ii) timely pay all Taxes due and payable with respect to the taxable periods covered by
such Post-Signing Returns, (iii) accrue a reserve in the books and records and financial statements
of any such entity consistent with past practice for all Taxes payable by such entity for which no
Post-Signing Return is due prior to the Effective Time, (iv) promptly notify Parent of any
Proceeding pending against or with respect to the Company or any Subsidiaries in respect any
material Tax and not settle or compromise any such Proceeding or other action
without Parents prior written consent and (v) promptly provide to the Parent a written copy
of any U.S. Federal income tax Post-Signing Return filed with the Internal Revenue Service. (b) The Company shall not, and shall not permit any Subsidiary to, enter into or effect any
transaction that would result in a material recognition of income or gain by the Company or any
Subsidiary, other than transactions entered into or effected in the Ordinary Course of Business
consistent with past practice. 51

ARTICLE VII ADDITIONAL AGREEMENTS 7.1 Efforts; Consents, Notices and Approvals. (a) General. Subject to the terms and conditions herein provided, each of the parties
hereto shall use its reasonable best efforts to take, or cause to be taken, all actions and to do,
or cause to be done, all things necessary, proper or advisable to consummate and make effective, as
promptly as practicable following the date of this Agreement, the Offer, the Merger and the other
transactions contemplated by this Agreement and the Stockholder Agreements, and to cooperate with
each of the other parties hereto in connection with the foregoing, including using its reasonable
best efforts: (i) to obtain all necessary waivers, consents and approvals from third parties, (ii)
to obtain all necessary consents, approvals and authorizations as are required to be obtained under
any Laws, (iii) to lift or rescind any Judgment adversely affecting the ability of the parties to
consummate the transactions contemplated hereby, (iv) to effect all necessary registrations,
applications, filings, notifications and submissions of information requested by governmental
authorities under the HSR Act, ITAR, the NISPOM and the Exon-Florio Act as promptly as is
reasonably practicable, and in any event within five (5) Business Days after the date hereof, (v)
to effect all other necessary registrations, notifications, applications and filings with
Governmental Entities, as promptly as is reasonably practicable, and (vi) to fulfill all conditions
to this Agreement. Notwithstanding anything to the contrary contained in this Agreement, in
connection with any filing or submission required or action to be taken by either Parent or the
Company to effect the Offer, the Merger and to consummate the other transactions contemplated
hereby, the Company shall not, without Parents prior written consent, commit to any divestiture
transaction, and neither Parent nor any of its Affiliates shall be required to divest or hold
separate or otherwise take or commit to take any action that limits its freedom of action with
respect to, or its ability to retain, the Company or any of the businesses or assets of Parent or
any of its Affiliates or that otherwise would result in a change, event, circumstance, development
or effect that is or is reasonably likely to have an adverse effect on the business, assets,
liabilities, capitalization, prospects, condition (financial or other), or results of operations of
Parent and/or Affiliates of Parent. Without expanding its obligations hereunder, the obligation of
Parent and Purchaser to use reasonable best efforts to obtain waivers, consents and approvals to
loan agreements, leases and other Contracts specifically shall not include any obligation to agree
to, and neither the Company nor any Subsidiary thereof shall agree (without the prior consent of
Parent) to, a modification of the terms of such documents, or to make any guaranty or monetary
payment in consideration of such waiver, consent or approval. Without prejudice or limitation to
the representations, warranties or covenants in this Agreement, each
party acknowledges and agrees that the issuance of security clearances is in the discretion of
the appropriate Governmental Entities, and no party shall bear responsibility for the results of
the exercise of such discretion. (b) Notifications by Company. The Company shall confer with Parent on a regular and
frequent basis as reasonably requested by Parent concerning operational matters and promptly advise
Parent orally and in writing of any significant change or event, including any having, or which,
insofar as reasonably can be foreseen, could have, a Material Adverse Effect. The Company shall
promptly provide to Parent (or its counsel) copies of all filings made by the 52

Company with any
Governmental Entity in connection with this Agreement and the transactions contemplated hereby.
Nothing contained in this Agreement shall give Parent or Purchaser, directly or indirectly, the
right to control or direct the operations of the Company prior to the consummation of the Offers.
Prior to the consummation of the Offers, the Company shall exercise, consistent with the terms and
conditions of this Agreement, control and supervision over its business operations. (c) State Takeover Law. Without limiting the generality of Section 7.1(a), if
any fair price or business combination or control share acquisition or anti-takeover
statute, or other similar statute or regulation or any state blue sky statute shall become
applicable to the transactions contemplated by this Agreement or by the Stockholder Agreements, the
Company and the Company Board shall grant such approvals and take such actions as are necessary so
that the transactions contemplated hereby and thereby may be consummated as promptly as practicable
on the terms contemplated hereby and thereby, and otherwise act to minimize the effects of such
statute or regulation on the transactions contemplated hereby or thereby. 7.2 Option to Acquire Additional Shares. (a) The Company hereby grants to Parent and Purchaser an irrevocable option (the
Purchaser Option) to purchase up to that number of newly issued and treasury shares of
the Company Common Stock (the Purchaser Option Shares) equal to the number of shares of
Company Common Stock that, when added to the number of shares of Company Common Stock owned by
Parent, Purchaser and their affiliates immediately following consummation of the Offer, shall
constitute one share more than ninety percent (90%) of the shares of Company Common Stock then
outstanding on a Fully Diluted Basis (after giving effect to the issuance of Purchaser Option
Shares) for a consideration per Purchaser Option Share equal to the Offer Consideration. (b) The Purchaser Option shall be exercisable only after the purchase of and payment for
shares of Company Common Stock pursuant to the Offer by Parent or Purchaser as a result of which
Parent, Purchaser and their Affiliates own beneficially at least 80% of the outstanding shares of
the Company Common Stock. Such Purchaser Option shall not be exercisable to the extent the number
of shares of Company Common Stock subject thereto exceeds the number of authorized shares of
Company Common Stock available for issuance. (c) In the event Parent and Purchaser wish to exercise the Purchaser Option, Purchaser shall
give the Company one (1) Business Day prior written notice specifying the number of shares of the
Company Common Stock that are or will be owned by Parent, Purchaser and their Affiliates
immediately following consummation of the Offer and specifying a place and a time for the closing
of such purchase. The Company shall, as soon as practicable following receipt of such notice,
deliver written notice to Purchaser specifying the number of Purchaser Option Shares. At the
closing of the purchase of Purchaser Option Shares, the portion of the purchase price owing upon
exercise of such Purchaser Option which equals the product of (x) the number of shares of Company
Common Stock purchased pursuant to such Purchaser Option, multiplied by (y) the Offer
Consideration, shall be paid to the Company in cash by wire transfer or cashiers check. 53

stockholders of the Company is required under the DGCL in order to consummate the Merger, the
Company shall, acting through the Company Board, at Parents request, as soon as practicable
following the acceptance for payment of, and payment for, shares of Company Common Stock by
Purchaser in the Offer (coordinating the timing thereof with Parent), duly call, give notice of,
convene and hold a meeting of its stockholders (the Company Stockholders Meeting) for the
purpose of obtaining such stockholder approval. Without limiting the generality of the foregoing,
the Company agrees that its obligations pursuant to the first sentence of this Section
7.3(a) shall not be affected by (i) the commencement, public proposal, public disclosure or
communication to the Company of any Acquisition Proposal or (ii) the withdrawal or modification by
the Company Board of its approval or recommendation of this Agreement, the Offer or the Merger.
Notwithstanding the foregoing, if Purchaser or any other Subsidiary of Parent shall acquire at

Parent, take all necessary and appropriate action to cause the Merger to become effective as soon
as practicable after the expiration of the Offer without a stockholders meeting in accordance with

required under the DGCL in order to consummate the Merger, to the extent permitted by the DGCL, and
in accordance with all relevant provisions thereof, at Parents request, the Company shall take all
necessary and appropriate action to obtain the requisite approval and adoption by the Companys
stockholders of this Agreement and the Merger by written consent without a meeting. (b) Preparation of Proxy Statement. If the adoption of this Agreement by the

and payment for, shares by Purchaser in the Offer, prepare and file with the SEC a proxy or
information statement (the Proxy Statement) in accordance with the Exchange Act and any
other applicable Laws, and will use its commercially reasonable efforts to respond to any comments
of the SEC or its staff and to cause the Proxy Statement to be mailed to the Companys stockholders
as promptly as practicable after responding to all such comments to the satisfaction of the staff.
The Company shall notify Parent promptly upon the receipt of any comments from the SEC or its staff
or any other government officials and of any request by the
SEC or its staff or any other government officials for amendments or supplements to the Proxy
Statement or for additional information, and shall supply Parent with copies of all correspondence
between the Company or any of its representatives, on the one hand, and the SEC, or its staff, or
any other government officials on the other hand with respect to the Proxy Statement. The Company
shall consult with Parent and its counsel prior to responding to any comments from the SEC or its
staff or any other government officials. If at any time prior to the Company Stockholders Meeting
there shall occur any event that should be set forth in an amendment or supplement to the Proxy
Statement, the Company shall promptly prepare and mail to its stockholders and file with the SEC

Company Common Stock purchased by Purchaser pursuant to the Offer and all other shares of Company
Common Stock owned by Parent or Purchaser or any other subsidiary of Parent to be voted in favor of
the adoption of this Agreement. 7.4 Notification of Certain Matters. The Company shall give prompt notice to Parent
of (a) the inaccuracy of any representation or warranty made by the Company contained in this
Agreement that is qualified as to materiality becoming untrue or inaccurate in any respect or any
such representation or warranty that is not so qualified becoming untrue or inaccurate in any
material respect, or (b) the failure by the Company to comply with or satisfy in any material
respect any covenant, condition or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that no such notification shall be deemed to cure any
breach or otherwise affect the representations, warranties, covenants or agreements of the Company
or waive the conditions to the obligations of the parties hereunder. Without limiting the
foregoing, the Company shall, promptly and in any event within 24 hours after it has notice of any
of the following, notify Parent of: (i) any notice or other communication from any Person alleging that the consent
of such Person is or may be required in connection with the transactions
contemplated by this Agreement; (ii) any notice or other communication from any Governmental Entity in
connection with the transactions contemplated by this Agreement; and (iii) any Proceedings commenced or, to the Companys Knowledge, threatened
against, relating to or involving or otherwise affecting the Company or any
Subsidiary which, if pending on the date of this Agreement would have been required
to have been disclosed pursuant to this Agreement or which relate to the
consummation of the transaction contemplated hereby. 7.5 Access to Information. (a) The Company shall, and shall cause each of its Subsidiaries and the Companys and such
Subsidiaries Representatives to, afford to Parent and its Representatives access, at all
reasonable times, during the period prior to the Effective Time, to all of the Companys and any of

foregoing, the Company shall, within two (2) Business Days of any request therefor, provide to
Parent the information described in Rule 14a-7(a)(2)(ii) under the Exchange Act and any information
to which a holder of Company Common Stock would be entitled under Section 262 of the DGCL (assuming
such holder met the requirements of such section). The Company shall use its commercially
reasonable efforts to secure for the Company access to and copies of the workpapers of its
independent public accountants. No information or knowledge obtained in any investigation pursuant

deemed to modify any representation or warranty
contained in the Agreement or the conditions to the obligations of the parties to consummate the
Offer or the Merger. (b) Neither any investigation conducted by Parent or its Representatives pursuant to this
Section 7.5 nor the results thereof shall affect any representation or warranty of the
Company contained in this Agreement or the ability of Parent to rely thereon. The parties
acknowledge that Parent and the Company have previously executed a non-disclosure agreement, dated
as of February 9, 2005 (the Non-Disclosure Agreement), which Non-Disclosure Agreement
shall continue in full force and effect in accordance with its terms, except as expressly modified
herein. 7.6 Public Disclosure. Except as may be required by Law or stock market regulations,
(a) the press release announcing the execution of this Agreement shall be issued only in such form
as shall be mutually agreed by the Company and Parent and (b) Parent and the Company shall each use
its reasonable best efforts to consult with the other party before issuing, and provide each other
with a reasonable opportunity to review and comment upon, any other press release or otherwise
making any public statement with respect to the transactions contemplated by this Agreement,
including the Offer and the Merger, and shall not issue any such press release or make any such
public statement prior to using such efforts; provided, however, that nothing in
this Section 7.6 shall be deemed to prohibit any party from making any disclosure which its
counsel deems necessary in order to satisfy such partys disclosure obligations imposed by Law or
stock market regulations. Parent and the Company shall each use its reasonable best efforts to
consult with the other party before issuing, and provide each other with a reasonable opportunity
to review and comment upon, any communications to Company employees with respect to the
transactions contemplated by this Agreement, including the Offer and the Merger. 7.7 Indemnification. (a) For six (6) years after the Effective Time, the Surviving Corporation will indemnify and
hold harmless (including advancement of expenses) the current and former directors and officers of
the Company and its Subsidiaries (the Covered Parties) in respect of acts or omissions
occurring on or prior to the Effective Time to the extent provided in their
respective Certificate of Incorporation, By-laws or similar governing instruments as in effect
as of the date of this Agreement which shall survive the Merger and shall continue in full force
and effect; provided, however, that such indemnification shall be subject to any
limitation imposed from time to time under applicable Law. As of the Effective Time, Parent shall
cause the Surviving Corporation to purchase a run-off directors and officers insurance and
indemnification policy (the Run-off D&O Insurance) for the Covered Parties providing
coverage for events occurring prior to the Effective Time for a period not less than six (6) years
from the Effective Time for all persons that are directors and officers of the Company or its

Subsidiaries on the date of this Agreement, on terms and conditions substantially similar to the
existing directors and officers insurance and indemnification policy with a six year aggregate
policy limit of $10 million; provided, however, that in no event shall the
Surviving Corporation be required to expend in excess of 200% of the current annual premium (the
Current Premium) of the Companys directors and officers insurance and indemnification
policy as in effect on the date hereof for Run-off D&O Insurance, and if the cost of such Run-off
D&O 56




---



##### 



Insurance would exceed 200% of the Current Premium, the Surviving Corporation shall purchase
the maximum amount of coverage for six (6) years as is available for 200% of the Current Premium.
If the Run-off D&O Insurance cannot be maintained, expires or is terminated or cancelled during
such six-year period, the Surviving Corporation will use reasonable efforts to replace such
coverage for the remainder of such period on terms and conditions substantially similar to the
existing directors and officers insurance and indemnification policy; provided,
however, that in no event shall the Surviving Corporation be required to expend in excess
of an aggregate of 100% of the Current Premium to replace the Run-off D&O Insurance, and if the
expense of replacing such Run-off D&O Insurance would exceed 100% of the Current Premium, the
Surviving Corporation shall purchase the maximum amount of coverage for six (6) years as is
available for 100% of the Current Premium. (b) In the event the Surviving Corporation or any of their successors or assigns (i)
consolidates with or merges into any other Person and shall not be the continuing or surviving
corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or
substantially all of its properties or assets to any Person, then, and in each such case, to the
extent necessary to effect the purposes of this Section 7.7, proper provision shall be made
so that the successors and assigns of the Surviving Corporation assume the obligations set forth in
this Section 7.7; provided, however, that, in the case of any such
assignment by the Surviving Corporation, the Surviving Corporation shall remain liable for all of
its obligations under this Agreement. This Section 7.7 shall survive the Effective Time,
is intended to benefit the current and former directors and officers of the Company and its
Subsidiaries, and shall be enforceable by any of them. 7.8 Stockholder Litigation. The Company shall keep Parent fully informed of any
stockholder litigation against the Company and its directors relating to this Agreement, the
Stockholder Agreements, the Offer, the Merger or any other transactions contemplated hereby;
provided, however, that no settlement of any such litigation shall be agreed to
without Parents prior written consent. 7.9 Obligation to Investigate Building. After the date hereof, and prior to the
completion of the Offer, (i) the Company shall use its reasonable best efforts to obtain from
Building such information and documents as shall
be necessary or advisable to enable the Company to confirm the accuracy of each of the
representations and warranties pertaining to Building that are set forth in Article IV, and
(ii) the Company shall give Parent and Purchaser prompt written notice in accordance with
Section 7.4 of any facts or circumstances that become known to the Company that would cause
any such representation or warranty to be untrue or incorrect in any respect. ARTICLE VIII CONDITIONS 8.1 Conditions to Obligation of Each Party to Effect the Merger. The respective
obligations of each party to effect the Merger shall be subject to the fulfillment at or prior to
the Effective Time of each of the following conditions: 57

mitigation proposal submitted in relation to this transaction by, and acceptable to, Parent in its
sole discretion, in accordance with the NISPOM; and (f) no Judgment issued by a court of competent jurisdiction or by any Governmental Entity nor
any Law shall be in effect, which would make the acquisition or holding by Parent or its
subsidiaries of the shares of Company Common Stock or shares of common stock of the Surviving
Corporation illegal or otherwise prevent the consummation of the Merger. ARTICLE IX TERMINATION, AMENDMENT AND WAIVER 9.1 Termination. This Agreement may be terminated and the Offer and Merger may be

Agreement by the stockholders of the Company or Purchaser, as follows: (a) subject to Section 1.3(c), by mutual written consent of Parent and the Company; (b) by either Parent or the Company: (i) if (x) as a result

has been a principal cause of or resulted in the failure of the Offer to be
consummated on or before the Outside Date; (ii) if any Governmental Entity issues a Judgment or takes any other action

Annex I; provided, however, solely in the case where such
failure of a condition set forth in paragraphs (vi)(E) or (vi)(F) of Annex I

covenant or agreement that is reasonably capable of being cured within ten (10)
days, Parent may not terminate pursuant to this Section 9.1(c)(i) if each condition
set forth in paragraphs (i), (vi)(E) and (vi)(F) of Annex I shall have been

agreements or representations by or among the parties hereto, or any of them, written or oral, with
respect to the subject matter hereof; provided, however, that the Non-Disclosure
Agreement shall remain in effect in accordance with its terms. 10.4 No Third Party Beneficiaries. Except for Section 7.7 above, this

beneficiary hereto. 10.5 Assignment. Neither this Agreement nor any of the rights, interests or
obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of

provision hereof is invalid or unenforceable, the parties hereto agree that the court making such
determination shall have the power to limit the term or provision, to delete specific words or
phrases, or to replace any invalid or unenforceable term or provision with a term or provision that
is valid and enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the
event such court does not exercise the power granted to it in the prior sentence, the parties
hereto agree to replace such invalid or unenforceable term or provision with a valid and
enforceable term or provision that will achieve, to the extent possible, the economic, business and
other purposes of such invalid or unenforceable term. 10.7 Counterparts and Signature. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original but all of which together shall be

parties need not sign the same counterpart. This Agreement may be executed and delivered by
facsimile transmission. 10.8 Interpretation. When reference is made in this Agreement to an Article or a

not been concluded with respect to the Offer, the Merger and the transactions contemplated hereby
(the Exon-Florio Condition); (iv) the Company shall not have taken commercially reasonable steps to advise the DSS of the
relevant aspects of the transaction and proposed terms of a proxy agreement, voting trust or other
arrangement calculated to be acceptable to the DSS, or the DSS shall have indicated that it is not

relation to this transaction by, and acceptable to, Parent in its sole discretion, in accordance
with the NISPOM (the DSS Condition); (v) any other required waiting periods, material clearances or approvals of any Governmental

with acceptance for payment or payment for shares of Company Common Stock. I-4
