AGREEMENT AND PLAN
OF MERGER AND REORGANIZATION

THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("Agreement") is made and entered into as of January 21, 2002, by and among: THE TITAN CORPORATION, a Delaware corporation ("Parent"); THUNDERBIRD ACQUISITION CORP., a California corporation and a wholly owned subsidiary of Parent ("Merger Sub"); and JAYCOR, INC. a California corporation (the "Company"). Certain other capitalized terms used in this Agreement are defined in Exhibit A.

RECITALS

WHEREAS, Parent, Merger Sub and the Company intend to effect a merger of Merger Sub with the Company (the "Merger") in accordance with this Agreement and the California General Corporation Law (the "CGCL"). Upon consummation of the Merger, Merger Sub will cease to exist, and the Company will become a wholly owned subsidiary of Parent.

WHEREAS, it is intended that the Merger qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code").

WHEREAS, this Agreement has been approved by the respective boards of directors of Parent, Merger Sub and the Company and has been adopted by Parent as the sole shareholder of Merger Sub.

WHEREAS, simultaneously with the execution of this Agreement, and as an inducement to Parent to enter into this Agreement, certain shareholders of the Company are entering into a Voting Agreement with Parent in the form of Exhibit F (the "Voting Agreement") pursuant to which each such shareholder has, among other things, agreed, upon the terms and subject to the conditions thereof, to vote the shares of Company Common Stock (the "Company Common Stock") for which he, she or it has a right to vote, including shares of Company Common Stock allocated to his or her account in the Company Employee Stock Ownership Plan (the "ESOP"), in favor of the Merger.

AGREEMENT

The parties to this Agreement agree as follows:

SECTION 1. DESCRIPTION OF TRANSACTION

1.1 Merger of Merger Sub into the Company. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company, and the separate existence of Merger Sub shall cease. The Company will continue as the surviving corporation in the Merger (the "Surviving Corporation").

1.2 Effect of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the CGCL.

1.3 Closing; Effective Time. The consummation of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of ▇▇▇▇▇▇ Godward LLP, ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ at 10:00 a.m. on a date to be designated by Parent which shall not be more than five (5) business days after the date on which the last of the conditions set forth in Section 6 and Section 7 has been satisfied or waived. The date on which the Closing actually takes place is referred to in this Agreement as the "Closing Date." Contemporaneously with or as promptly as practicable after the Closing, a properly executed agreement of merger (the "Agreement of Merger") shall be filed with the Secretary of State of the State of California. The Merger shall become effective at the time specified in the Agreement of Merger or, if no time is specified, at the time the Agreement of Merger is filed with the Secretary of State of the State of California (the "Effective Time").

A-1

1.4 Articles of Incorporation and Bylaws; Directors and Officers. Unless otherwise determined by Parent prior to the Effective Time:

(a) the Articles of Incorporation of the Company immediately prior to the Effective Time shall be the Articles of Incorporation of the Surviving Corporation;

(b) the Bylaws of the Company immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation after the Effective Time; and

(c) the directors and officers of Merger Sub immediately prior to the Effective Time shall be the directors and officers of the Surviving Corporation immediately after the Effective Time.

1.5 Conversion of Shares.

(a) Subject to Sections 1.8(a), 1.9 and 1.10, at the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any shareholder of the Company:

(i) each share of Company Common Stock outstanding immediately prior to the Effective Time shall be converted into the right to receive that fraction of a share of the common stock of Parent, $0.01 par value per share, together with the associated preferred stock purchase rights ("Parent Common Stock"), equal to the "Applicable Fraction", it being understood that certain of the shares of Parent Common Stock issuable pursuant to this Section 1.5(a)(i) shall be held in escrow in accordance with Section 1.10 and Section 1.14; and

(ii) each share of the common stock of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation.

1.6 Repurchase Rights; Options. No shares of Company Common Stock outstanding immediately prior to the Effective Time will be unvested or subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with the Company. All options to purchase Company Common Stock issued under the Company Stock Plans shall be exercised on or prior to the Closing Date or terminated as of the Effective Time in accordance with the Company Option Plan. Neither the Parent nor the Surviving Corporation shall assume, become responsible for or otherwise assume any obligations with respect to, any outstanding options, warrants or other rights to purchase capital stock of the Company.

1.7 Closing of the Company's Transfer Books. At the Effective Time, holders of certificates representing shares of capital stock of the Company that were outstanding immediately prior to the Effective Time shall cease to have any rights as shareholders of the Company, except the right to receive the Merger Consideration as set forth in this Agreement and the Agreement of Merger, and the stock transfer books of the Company shall be closed with respect to all shares of such capital stock of the Company outstanding immediately prior to the Effective Time. No further transfer of any such shares of capital stock of the Company shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of capital stock of the Company (a "Company Stock Certificate") is presented to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.8.

1.8 Exchange of Certificates.

(a) As soon as practicable prior to the Effective Time, Parent will deliver to the Company a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify and instructions for use in effecting the surrender of Company Stock Certificates in exchange for the Merger Consideration. At the Closing or thereafter, upon surrender of a Company Stock Certificate to Parent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by Parent, Parent shall (i) deliver to the registered holder of such Company Stock Certificate a certificate representing that number of shares of Parent Common Stock that such

A-2

holder has the right to receive pursuant to Section 1.5 less such holder's Pro Rata Escrow Shares (as defined in clause (ii) of this sentence) and less such holder's Pro Rata Adjustment Shares (as defined in clause (iii) of this sentence), (ii) deliver to the Escrow Agent (as defined below) under the Escrow Agreement (as defined below) on behalf of such holder a certificate in the name of the Escrow Agent representing that number of shares of Parent Common Stock equal to the product of (A) that number of Merger Shares equal to the quotient of (1) $4,200,000 divided by (2) the Parent Average Trading Price (the "Escrow Shares") and (B) the quotient of (1) the total number of shares of Company Common Stock held by such holder immediately prior to the Effective Time, divided by (2) the total number of shares of Company Common Stock outstanding immediately prior to the Effective Time (the "Pro Rata Escrow Shares"), and (iii) deliver to the Escrow Agent under the Escrow Agreement on behalf of such holder a certificate in the name of the Escrow Agent representing that number of shares of Parent Common Stock equal to the product of (A) that number of Merger Shares equal to the quotient of (1) $1,100,000 divided by (2) the Parent Average Trading Price (the "Adjustment Shares") and (B) the quotient of (1) the total number of shares of Company Common Stock held by such holder immediately prior to the Effective Time, divided by (2) the total number of shares of Company Common Stock outstanding immediately prior to the Effective Time (the "Pro Rata Adjustment Shares") provided that the certificates representing Parent Common Stock to be delivered to the holder of a Company Stock Certificate under clause (i) above and to the Escrow Agent under clauses (ii) and (iii) above shall, in each case, represent only whole shares of Parent Common Stock. In lieu of any fractional shares to which such holder would otherwise be entitled, after combining any fractional interests of such holder into as many whole shares as is possible, the holder of such Company Stock Certificate shall be paid in cash an amount equal to the sum of (1) the dollar amount (rounded to the nearest whole cent) determined by multiplying the Parent Average Trading Price by the fraction of a share of Parent Common Stock that would otherwise be deliverable to such holder under clause (i) above, (2) the dollar amount (rounded to the nearest whole cent) determined by multiplying the Parent Average Trading Price by the fraction of a share of Parent Common Stock that would otherwise be deliverable to the Escrow Agent under clause (ii) above and (3) the dollar amount (rounded to the nearest whole cent) determined by multiplying the Parent Average Trading Price by the fraction of the share of Parent Common Stock that would otherwise be deliverable to such holder under clause (iii) above. Notwithstanding the foregoing, Parent may deliver to the Escrow Agent two certificates representing the total number of Escrow Shares and Adjustment Shares, respectively, pursuant to this Section 1.8(a) in lieu of issuing separate certificates representing such holder's Pro Rata Escrow Shares or Pro Rata Adjustment Shares. All Company Stock Certificates so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.8, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the Merger Consideration in accordance with this Agreement. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the issuance of any certificate representing Parent Common Stock or the payment of cash in lieu of fractional shares, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against Parent or the Surviving Corporation with respect to such Company Stock Certificate.

(b) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of any fractional share shall be paid to any such holder, until such holder surrenders such Company Stock Certificate in accordance with this Section 1.8 (at which time such holder shall be entitled to receive all such dividends and distributions and such cash payment).

(c) Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable to any holder or former holder of capital stock of the

A-3

Company pursuant to this Agreement such amounts as Parent or the Surviving Corporation may be required to deduct or withhold therefrom under the Code or under any provision of state, local or foreign tax law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(d) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of capital stock of the Company for any shares of Parent Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, delivered to any public official pursuant to any applicable abandoned property, escheat or similar law.

1.9 Dissenters' Rights.

(a) Notwithstanding anything in this Agreement to the contrary, shares of capital stock of the Company held by a holder who, pursuant to Subchapter 13 of the CGCL or any successor provision, has the right to demand and properly demands an appraisal of such shares of capital stock of the Company ("Dissenting Shares"), shall not be converted into the right to receive Parent Common Stock as set forth in Section 1.5, unless such holder fails to perfect or otherwise loses such holder's right to such appraisal, if any. If, after the Effective Time, such holder fails to perfect or loses any such right to appraisal, such holder's Dissenting Shares shall be treated as having been converted as of the Effective Time into the right to receive the Merger Consideration. At the Effective Time, any holder of Dissenting Shares shall cease to have any rights with respect thereto, except the rights provided in Subchapter 13 of the CGCL or any successor provision and as provided in the immediately preceding sentence. The Company shall give prompt notice to Parent of any demands received by the Company for appraisal of shares of capital stock of the Company and the opportunity to participate in all negotiations and proceedings with respect to any such demand. Except to the extent otherwise required by the CGCL, the Company shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand unless Parent shall have consented in writing to such payment or settlement offer.

1.10 Escrow of Parent Common Stock.

(a) Upon the Closing, Parent shall withhold the Escrow Shares and deliver such shares to a bank or trust company with assets of at least $100,000,000 selected by Parent as escrow agent (the "Escrow Agent"), to be held by the Escrow Agent as collateral to secure the rights of the Indemnitees under Section 9 hereof and as a "purchase price adjustment fund" in the event that there are insufficient Adjustment Shares to fund any Parent Adjustment Amount pursuant to Section 1.14. The Escrow Shares shall be held pursuant to the provisions of an escrow agreement substantially in the form of Exhibit B-1 (the "Escrow Agreement"). The Escrow Shares will be represented by a certificate or certificates issued in the name of the Escrow Agent and will be held in an indemnification fund by the Escrow Agent until April 15, 2003 (from the Effective Time to such date, the "Escrow Period"); provided, however that in the event any Indemnitee has made a claim under Section 9 prior to the end of the Escrow Period, then the Escrow Period shall continue (and the Escrow Agent will continue to hold such shares in escrow) until such claim is fully and finally resolved. In the event that the principal terms of this Agreement are approved by the Company's shareholders, then all such shareholders shall, without any further act of any Company shareholder, be deemed to have consented to and approved (i) the use of the Escrow Shares as collateral to secure the rights of the Indemnitees under Section 9 in the manner set forth herein and in the Escrow Agreement, and (ii) the appointment of the Company Shareholders' Representative (as defined in Section 10.1) as the representative under the Escrow Agreement of the Persons receiving Merger Consideration under this Agreement and as the attorney-in-fact and agent for and on behalf of each such Person (other than holders of Dissenting Shares).

A-4

(b) Upon the Closing, Parent shall withhold the Adjustment Shares and deliver such shares to the Escrow Agent, to be held in a "purchase price adjustment fund" by the Escrow Agent for purposes of the adjustments contemplated in Section 1.14 pursuant to the terms of the Escrow Agreement. The Adjustment Shares shall in no event be used as collateral to secure the rights of the Parent Indemnitees under Section 9 hereof. In the event and to the extent the Adjustment Shares are not sufficient to fund the Parent Adjustment Amount, Parent shall be entitled to use the Escrow Fund as the "purchase price adjustment fund" and cancel the appropriate number of Escrow Shares or withdraw the appropriate amount of Escrow Cash (as defined in the Escrow Agreement), as applicable, in order for Parent to get fully reimbursed for the entire Parent Adjustment Amount.

1.11 Tax Consequences. For federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368 of the Code. The parties to this Agreement hereby adopt this Agreement as a "plan of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

1.12 Accounting Treatment. For accounting purposes, the Merger is intended to be treated as a "purchase."

1.13 Further Action. If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement and any Related Agreement or to vest the Surviving Corporation or Parent with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

1.14 Working Capital Adjustment.

(a) On the Closing Date, the Company shall deliver to Parent a consolidated balance sheet of the Company dated as of the Closing Date (the "Closing Balance Sheet"). The Closing Balance Sheet shall present fairly in all material respects the financial condition of the Company on the Closing Date in conformity with GAAP on a basis consistent with the Company Financial Statements (as defined below) and the Unaudited Interim Balance Sheet (as defined below). Within thirty (30) days following the Closing the Company shall provide to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP all schedules and materials reasonably requested by ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP. Within sixty (60) days following the date on which ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP receives such schedules and materials, it shall perform an audit of the Closing Balance Sheet, including a determination of Working Capital as of the Closing Date, and shall issue a draft audit report on the Closing Balance Sheet as of the Closing Date, which report shall state the amount of Working Capital as of the Closing Date (the "Working Capital Report"). Once ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP completes the audit, Parent shall provide to the Company Shareholders' Representative a copy of the draft audit report on the audited Closing Balance Sheet as well as the Working Capital Report (together, the "Closing Reports"). The Closing Reports shall be subject to review by Ernst & Young, LLP (the "Company Auditors") which review shall be completed no later than thirty (30) days after the Company Shareholders' Representative receives the Closing Reports. If the Company Shareholders' Representative does not object to the Closing Reports within fifteen days of the expiration of the thirty-day period for review by the Company Auditors, then the Closing Report shall be deemed final. If the opinions of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP and the Company Auditors differ as to the necessity of any audit adjustment or the calculation of Working Capital, each of a senior management representative of Parent and the Company Shareholders' Representative will have thirty (30) days from the date the objection was raised by the Company Shareholders' Representative to resolve the dispute (the "Initial Resolution Period"). If the member of senior management and the Company Shareholder Representative cannot resolve the dispute during the Initial Resolution Period, such parties shall select a third mutually acceptable major accounting firm to arbitrate the dispute under the rules it imposes (the "Neutral Auditor"). The decision of the Neutral Auditor shall be made within 30 days after its engagement (which engagement shall be made no later than 5 days after the end of the Initial Resolution Period),

A-5

shall be set forth in a written statement delivered to the Company Shareholder Representative and Parent and shall be final, binding, conclusive on such parties for all purposes hereunder. Each such party shall be responsible for any fees and expenses incurred by such party's auditors; provided, however, that the Company Shareholders' Representative shall be entitled to reimbursement out of the Escrow Fund of reasonable costs and expenses related to its actions under this Section 1.14(a) including the cost of Ernst & Young's review in an amount not to exceed, together with any amounts payable to the Company Shareholders' Representative pursuant to Section 10.1(e), $50,000 in the aggregate (the "Permitted Reimbursement Amount"). The Neutral Auditor shall allocate its fees between the Company Shareholder Representative and Parent according to the degree to which the positions of the respective parties are not accepted by the Neutral Auditor. The Closing Report shall be deemed to be the written statement delivered by the Neutral Auditor or, if any dispute is resolved in the Initial Resolution Period, the final Closing Report as agreed by the parties.

(b) If (i) the Final Excess Working Capital Amount minus the Excess Working Capital Amount is greater than zero, (ii) the Deficient Working Capital Amount minus the Final Deficient Working Capital Amount is greater than zero or (iii) the Closing Balance Sheet showed a Deficient Working Capital Amount and the Closing Report showed a Final Excess Working Capital Amount or no Deficient Working Capital Amount, then Parent shall issue and deposit with the Escrow Agent in the purchase price adjustment fund for the benefit of the former holders of Company Common Stock the number of shares of Parent Common Stock equal to the Company Adjustment Amount divided by the Parent Average Trading Price. "Company Adjustment Amount" shall mean (i) in the case of Section 1.14(b)(i), the amount equal to the Final Excess Working Capital Amount minus the Excess Working Capital Amount, (ii) in the case of Section 1.14(b)(ii), the amount equal to the Deficient Working Capital Amount minus the Final Deficient Working Capital Amount, and (iii) in the case of Section 1.14(b)(iii) the sum of the Final Excess Working Capital Amount and the Deficient Working Capital Amount; provided, however, that in the case of each of (i), (ii) and (iii) the Company Adjustment Amount will be increased by the Broker Commission Amount, if any. Any positive difference between the Broker Commission Amount and the Parent Adjustment Amount (as defined below) shall be deemed a Company Adjustment Amount.

(c) If (i) the Excess Working Capital Amount minus the Final Excess Working Capital Amount is greater than zero, (ii) the Final Deficient Working Capital Amount minus the Deficient Working Capital Amount is greater than zero or (iii) the Closing Balance Sheet showed an Excess Working Capital Amount and the Closing Report showed a Final Deficient Working Capital Amount or no Excess Working Capital Amount, then Parent shall be entitled to receive cash out of the adjustment account equal to the Parent Adjustment Amount if the Adjustment Shares have been sold, and, to the extent there is insufficient cash to cover the Parent Adjustment Amount, to reduce the Adjustment Shares by and cancel the number of shares of Parent Common Stock equal to the lower of (i) the quotient of (x) the Parent Adjustment Amount less any amount paid in cash (which may be zero) divided by (y) the Parent Average Trading Price and (ii) the total number of Adjustment Shares and Escrow Shares. "Parent Adjustment Amount" shall mean (i) in the case of Section 1.14(c)(i), the amount equal to the Excess Working Capital Amount minus the Final Excess Working Capital Amount, (ii) in the case of Section 1.14(c)(ii), the amount equal to the Final Deficient Working Capital Amount minus the Deficient Working Capital Amount, and (iii) in the case of Section 1.14(c)(iii) the sum of the Excess Working Capital Amount and the Final Deficient Working Capital Amount; provided, however, that in the case of each of (i), (ii) and (iii) the Parent Adjustment Amount will be decreased by the Broker Commission Amount, if any.

SECTION 2. REPRESENTATIONS AND WARRANTIES OF THE ACQUIRED CORPORATIONS

Except as set forth on the Company Disclosure Schedule, which shall be organized in Parts corresponding to the numbering in this Section 2 with disclosures in each Part specifically corresponding to or cross-referencing another Part of the Company Disclosure Schedule specifically

A-19

reserves for payment have been established). There are no liens for Taxes upon any of the assets of the Acquired Corporations except liens for current Taxes not yet due and payable.

None of the Acquired Corporations has been, and none of the Acquired Corporations will be, required to include any adjustment in taxable income for any tax period (or portion thereof) pursuant to Section 481 or 263A of the Code or any comparable provision under state or foreign Tax laws as a result of transactions or events occurring, or accounting methods employed, prior to the Closing. None of the Acquired Corporations is a party to any Contract, nor does it have any obligation (current or contingent), to compensate any individual for excise taxes paid pursuant to Section 4999 of the Code. Notwithstanding any disclosure in the Company Disclosure Schedule, none of the Acquired Corporations has made any distribution of stock of any "controlled corporation" as that term is defined in Section 355(a)(1) of the Code and the Acquired Corporations have no Liability for Taxes as a result of any such distribution, and the Merger shall not result in any such Taxes.

(e) There is no agreement, plan, arrangement or other Contract covering any employee or independent contractor or former employee or independent contractor of the Acquired Corporations that, considered individually or considered collectively with any other such Contracts, will, or could reasonably be expected to, give rise directly or indirectly to the payment of any amount that would not be deductible pursuant to Section 280G or Section 162 of the Code. None of the Acquired Corporations has, at any time, been a member of a group (including an affiliated group, within the meaning of Section 1504 of the Code) with which it has filed or been included in a combined, consolidated or unitary income Tax Return, other than a group of which the Company is or was the common parent.

(f) The Company and, as applicable, any Subsidiary or Subsidiaries with which the Company files a combined, consolidated or unitary Tax Return will have no federal, state, local, or foreign tax or other Liability arising out of the Stock Distribution Transaction. Assuming the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, no Tax liability or restriction, reduction or limitation on or of favorable Tax attributes (such as losses or credits, loss or credit carryovers, basis or deduction) will arise directly or indirectly as a result of the Merger other than pursuant to Section 382 and Section 383 of the Code. The Company Disclosure Schedule sets forth the amount of available net operating loss and credit carryovers to the Acquired Corporations as of December 31, 2001.

The Acquired Corporations have never been a member of an "affiliated service group" within the meaning of Section 414(m) of the Code. To the knowledge of the Acquired Corporations, the Acquired Corporations have never made a complete or partial withdrawal from a multiemployer plan, as such term is defined in Section 3(37) of ERISA, resulting in "withdrawal liability," as such term is defined in Section 4201 of ERISA (without regard to subsequent reduction or waiver of such liability under either Section 4207 or 4208 of ERISA).

A reasonable estimate of any cost, expenses and Liabilities related to the matter set forth in Part 2.15(k) of the Company Disclosure Schedule, including a $160,000 payment to ▇▇. ▇▇▇▇ ▇▇▇▇▇▇, shall have been accrued as current liabilities on the Closing Balance Sheet.

There is not now pending, and no Person has threatened to commence, any such slowdown, work stoppage, labor dispute or union organizing activity or any similar activity or dispute.

Parent will use its commercially reasonable efforts to maintain the effectiveness of the S-3 Registration Statement and other applicable registrations, qualifications and compliances until the earlier of six (6) months after the Effective Time or the date of final sale by the ESOP of all Registrable Shares from the Closing Date (the "Registration Effective Period"), and from time to time will amend or supplement the S-3 Registration Statement and the prospectus contained therein as and to the extent necessary to comply with the Securities Act, the Exchange Act and any applicable state securities statute or regulation, subject to the limitations and qualifications in Section 5.3(h).

Each Company employee who continues to be employed by Company, Parent or any of its Affiliates ("Retained Employee") shall be eligible to receive salary and benefits (such as medical benefits, bonuses, 401(k) and stock options) maintained for employees of Parent on the same terms and conditions applicable to similarly situated employees of Parent. Each Retained Employee shall be given credit, for the purposes of any service requirements for participation eligibility, or vesting, of his or her period of continuous service with the Company prior to the Effective Time. No Retained Employee, or any of his or her eligible dependents, who, at the Effective Time, are participating in the Company group health plan shall be excluded from the Parent's group plan, or limited in coverage thereunder, by reason of any waiting period restriction or pre-existing condition limitation.

(b) The obligations of Parent and the Surviving Corporation under this Section 5.9 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Person to whom this Section 5.9 applies without the consent of such affected Indemnified Person (it being expressly agreed that the Indemnified Person to whom this Section 5.9 applies shall be third party beneficiaries of this Section 5.9).

(c) In the event Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, honor the indemnification obligations set forth in this Section 5.9.

The ESOP will be amended to provide that the Plan Committee will be permitted to appoint and remove any member by majority vote, and that the membership of such Plan Committee will be expanded to five members. Parent shall notify and obtain prior written consent from the Plan Committee with respect to each action with respect to the ESOP undertaken by the Parent or Merger Sub (or their respective successors-in-interest), including any amendments to the ESOP. All actions of the Plan Committee which require approval by either the Parent or Merger Sub (or their respective successors-in-interest) shall be approved by the Parent, Merger Sub, or respective successor-in-interest, unless such action by the Plan Committee would result in a violation of a fiduciary duty with respect to the ESOP or is contrary to applicable Legal Requirements, and no action of the Plan Committee which would not violate either a fiduciary duty with respect to the ESOP or any applicable Legal Requirement shall be voided, overruled or disapproved of by Parent or Merger Sub (or any of their respective successors-in-interest).

SECTION 9. INDEMNIFICATION, ETC.

(a) The representations and warranties made by the Company in this Agreement, the Company Disclosure Schedule or any other document, certificate, schedule or instrument delivered or executed in connection herewith (including the representations and warranties set forth in Section 2 and the representations set forth in the Company Compliance Certificate) shall survive the Closing and shall expire at the end of the Escrow Period; provided, however, that if, at any time prior to the end of the Escrow Period, any Indemnitee delivers to the Company Shareholders' Representative a written notice alleging the existence of an inaccuracy in or a breach of any of the representations and warranties made by the Company (and setting forth in reasonable detail the basis for such Indemnitee's belief that such an inaccuracy or breach may exist) and asserting a claim for recovery under Section 9.2 based on such alleged inaccuracy or breach, then the representation or warranty underlying the claim asserted in such notice shall survive the end of the Escrow Period until such time as such claim is fully and finally resolved. All of the covenants, agreements and obligations of the parties contained in this Agreement, the Company Disclosure Schedule or any other document, certificate, schedule or instrument delivered or executed in connection herewith shall survive (i) until fully performed or fulfilled, unless non-compliance with such covenants, agreements or obligations is waived in writing by the party or parties entitled to such performance or (ii) if not fully performed or fulfilled, until the expiration of the relevant statute of limitations. All representations and warranties made by Parent and Merger Sub shall terminate and expire at the end of the Escrow Period, and any liability of Parent or Merger Sub with respect to such representations and warranties shall thereupon cease.

(b) The representations, warranties, covenants and obligations of each party, and the rights and remedies that may be exercised by the Indemnitees or the Company Shareholders' Representative on behalf of the Company shareholders, shall not be limited or otherwise affected by or as a result of any information furnished to, or any investigation made by or knowledge of, any of such parties. The parties recognize and agree that the representations and warranties also operate as bargained for promises and risk allocation devices and that, accordingly, any party's knowledge, and the waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, shall not affect the right to indemnification or payment of Damages pursuant to this Article 9, or other remedy based on such representations, warranties, covenants, and obligations.

(c) For purposes of this Section 9, each statement or other item of information set forth in the Company Disclosure Schedule shall be deemed to be a representation and warranty made by the Company in this Agreement. Notwithstanding anything herein to the contrary, including Section 6.1, the representations and warranties of the Company contained in this Agreement shall, for purposes of the Indemnifying Party's obligations pursuant to this Article 9, be deemed to be made as of the date of this Agreement and as of the Closing Date (except to the extent any such representation or warranty expressly speaks of an earlier date) without regard to the exceptions set forth in the Company Compliance Certificate, but subject to the exceptions set forth in the Company Disclosure Schedule.

9.2 Indemnification.

(a) From and after the Effective Time (but subject to Section 9.1(a)), the Escrow Fund (the "Indemnifying Party") shall hold harmless and shall indemnify each Indemnitee from and against, and shall be compensated, reimbursed and paid for, any Damages which are directly or indirectly suffered or incurred by any Indemnitee or to which any Indemnitee may otherwise become subject (regardless of whether or not such Damages relate to any third-party claim) and which arise from or as a result of, or are directly or indirectly connected with: (i) any inaccuracy in or breach of any representation or warranty of the Company set forth in this Agreement, the Company Disclosure Schedule or any other document, certificate, schedule or instrument delivered or executed in connection herewith (including

9.4 Offset Against Escrow Fund; Sole Remedy.

(a) Subject to Section 9.3 and Section 9.4(b) below, in the event any Indemnitee shall suffer any Damages for which such Indemnitee is entitled to indemnification under this Section 9, such Indemnitee shall be entitled to recover such Damages solely by obtaining either cash from the Escrow Fund or that number of Escrow Shares equal in value (as determined in accordance with the terms and conditions of the Escrow Agreement) to the aggregate amount of such Damages, and such recovery shall be made from the Escrow Fund on a basis proportional to the Escrow Shares contributed under the Escrow Agreement by or on behalf of each Company shareholder.

(b) From and after the Effective Time, the Company shareholders shall have no liability for Damages in excess of the number of Escrow Shares plus any cash or cash equivalents held under the Escrow Agreement except for Damages directly or indirectly related to (i) fraud or intentional misrepresentation by the Company or any willful breach of this Agreement by the Company or (ii) any breach of the representations set forth in Section 2.3; provided, however, that nothing in this Section 9.4(b) shall preclude Parent from seeking injunctive relief or specific performance with respect to any covenant, agreement or obligation of the Company contained in this Agreement. Notwithstanding anything in this Agreement to the contrary, the parties hereto acknowledge and agree that the provisions of this Article 9 with respect to indemnification shall not be the exclusive remedy for Parent, and that Parent shall have the right to recover Damages from the holders of Company Securities for, and that such holders shall be severally but not jointly liable for their respective pro rata portion of, Damages (such pro rata portion to be determined based on the amount of Merger Consideration payable with respect to such holder's Company Securities, relative to the aggregate

A-50

Merger Consideration payable with respect to all Company Securities), in each case up to, and not to exceed, the amount of Merger Consideration paid with respect to such holders' Company Securities (it being understood that any amount recovered pursuant to this Section 9.4(b), or any amount of the Escrow Fund not received by holders of Company Securities upon distribution of the Escrow Fund, shall not be considered as Merger Consideration paid with respect to such holders' Company Securities for purposes of this Section 9.4(b)) directly or indirectly arising or resulting from (i) fraud or intentional misrepresentation by the Company or any willful breach of this Agreement by the Company or (ii) any breach of the representations set forth in Section 2.3.

9.6 Defense of Third Party Claims.

(a) In the event of the assertion or commencement by any Person of any claim or Legal Proceeding (whether against the Surviving Corporation, against Parent or against any other Person) with respect to which any of the Indemnitees may be entitled to indemnification or any other remedy pursuant to this Section 9, Parent shall promptly give the Company Shareholders' Representative and the Escrow Agent written notice of such claim or Legal Proceeding (a "Claim") provided, however, that any failure on the part of Parent to so notify the Company Shareholders' Representative shall not limit any of the Indemnitees' rights to indemnification under this Section 9 (except to the extent such failure materially prejudices the defense of such Legal Proceeding).

(b) Within ten days of delivery of such written notice, the Company Shareholders' Representative may elect (by written notice delivered to Parent) to take all necessary steps properly to contest any Claim involving third parties or to prosecute such Claim to conclusion or settlement. If the Company Shareholders' Representative makes the foregoing election, an Indemnitee will have the right to participate at its own expense in all proceedings. If the Company Shareholders' Representative does not make such election within such period or fails to diligently contest such Claim after such election, then the Indemnitee shall be free to handle the prosecution or defense of any such Claim, and will take all necessary steps to contest the Claim involving third parties or to prosecute such Claim to conclusion or settlement, and will notify the Company Shareholders' Representative of the progress of any such Claim, will permit the Company Shareholders' Representative, at the sole cost of the Company Shareholders' Representative, to participate in such prosecution or defense and will provide the Company Shareholders' Representative with reasonable access to all relevant information and documentation relating to the Claim and the prosecution or defense thereof. Notwithstanding the foregoing, Parent shall control the defense and settlement of any Claim with respect to Taxes.

(c) Notwithstanding the foregoing, if a Claim includes Damages equal to an amount in excess of the value of the Escrow Shares on the date of the Claim, or relates to any Proprietary Assets or other intellectual property issues, or involves any action by any Governmental Body, whether arising under a Governmental Contract or otherwise, Parent shall have the right, at its election, to proceed with the defense of such claim or Legal Proceeding on its own. In any case, the party not in control of the Claim will reasonably cooperate with the other party in the conduct of the prosecution or defense of such Claim.

(d) Neither party will compromise or settle any such Claim without the written consent of either Parent (if the Company Shareholders' Representative defends the Claim) or the Company Shareholders' Representative (if Parent or other Indemnitees defend the Claim), such consent not to be unreasonably withheld. Notwithstanding anything in this Agreement to the contrary, Parent may withhold its consent to any settlement that does not include a full general release of all the claims

A-51

against Indemnitee from all parties to the litigation or that requires Parent or any of its Affiliates to perform any covenant or refrain from engaging in any activity.

(e) If Parent proceeds with the defense of any such claim or Legal Proceeding all reasonable expenses relating to the defense of such claim or Legal Proceeding shall be satisfied first out of the Escrow Shares in the manner set forth in the Escrow Agreement and then, to the extent the same are liable under this Agreement, from the Company shareholders.

9.7 Exercise of Remedies; Tax Treatment.

(a) No Indemnitee (other than Parent or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement or under the Escrow Agreement unless Parent (or any successor thereto or assign thereof) shall have consented to the assertion of such indemnification claim or the exercise of such other remedy.

(b) The parties shall report any indemnification payment made pursuant to this Article 9 as a purchase price adjustment unless otherwise required by applicable Legal Requirements.
