(b) Effect on Target Warrants.

(i) Any Target Common Warrants which are not exercised by the Effective Time shall be converted into and represent the right to receive the amount of cash equal to the Per Share Merger Consideration multiplied by the number of shares of Target Common Stock issuable upon exercise of such Warrant (assuming a net exercise of such Warrant).

(ii) The Target Preferred Warrant, to the extent it is not exercised by the Effective Time, shall be converted into and represent the right to receive cash in the amount that the holder of the Target Preferred Warrant is entitled to pursuant to § 3(d)(ii) below.

Except as set forth in § 3(e) and subject to the terms and conditions of this Agreement, in exchange for Certificates and/or affidavits representing all of its outstanding Target Common Stock (other than Dissenting Shares) delivered to the Exchange Agent pursuant to this Agreement, each Target Common Stockholder shall be entitled to receive an amount in cash equal to the Per Share Merger Consideration multiplied by the number of shares of Target Common Stock owned by such Target Common Stockholder as reflected in the capitalization table attached hereto as Exhibit D. Pursuant to § 2(e)(ii), Parent shall transfer via wire transfer in immediately available funds the Exchange Amount to a single account specified in writing by the Exchange Agent. The Target Common Stockholder Merger Consideration shall be payable from the Exchange Amount following the Effective Time by the Exchange Agent to the Target Common Stockholders (other than Dissenting Stockholders) pursuant to the terms of this Agreement.

(ii) Target Preferred Stock. Except as set forth in § 3(e) and subject to the terms and conditions of this Agreement, in exchange for Certificates and/or affidavits representing all of its outstanding Target Preferred Stock (other than Dissenting Shares) delivered to the Exchange Agent pursuant to this Agreement, each Target Preferred Stockholder shall be entitled to receive an amount in cash equal to the Per Share Merger Consideration multiplied by the number of shares of Target Common Stock issuable upon conversion of each share of Target Preferred Stock owned by such Target Preferred Stockholder as reflected in the capitalization table attached hereto as Exhibit D.

(iii) Restricted Stock. Each share of Target Common Stock (other than Dissenting Shares) subject to restricted stock agreements (“Restricted Target Common Stock”) shall be cancelled and converted into the right to receive from Parent the Per Share Merger Consideration therefor in accordance with the provisions of § 3(c)(iii) and 3(c)(iv); provided, however, the Target will not take any action to remove or shorten any restriction periods or other terms and conditions currently applicable to such Restricted Target Common Stock other than as specifically required in either the Target Stock Plan or any restricted stock agreement governing such Restricted Target Common Stock. Upon the restrictions being removed from a holder’s shares of Restricted Target Common Stock, Parent shall distribute to such holder from the eighty-five percent (85%) of the Total Unvested Restricted Stock Consideration retained by the Parent pursuant to § 2(d)(ii)(E), eighty-five percent (85%) of such holder’s Pro Rata Portion of the Total Merger Consideration related to such shares of Restricted Target Common Stock and such holder shall be entitled to receive fifteen (15%) of such holder’s Pro Rata Portion of the Total Merger Consideration related to such shares of Restricted Target Common Stock held in escrow to the extent provided in § 2(e)(iv), less any amounts of the Total Merger Consideration previously distributed under this Agreement and less any portion of such Pro Rata Portion of the Total Merger Consideration attributable to such holder’s shares of Restricted Target Common Stock which are subject to restriction as of the Effective Time (such portion, the “Unvested Restricted Stock Consideration”).

(iv) Unvested Restricted Stock Consideration. The parties hereto acknowledge that the amount of the Per Share Merger Consideration has been determined assuming that any restrictions on the shares of Restricted Target Common Stock have been removed as of the Effective Time. Accordingly, to the extent that after the Effective Time any portion of the eighty-five percent (85%) of the Unvested Restricted Stock Consideration is not actually paid out by Parent to any holder of Restricted Target Common Stock or is not entitled to be distributed to any holder of Restricted Common Stock pursuant to § 3(d)(iii) (collectively, the “Forfeited Consideration”), each share of Target Common Stock (other than Dissenting Shares) issued and outstanding as of immediately prior to the Effective Time (assuming the prior conversion of each share of Target Preferred Stock into Target Common Stock) and each share of Target Common Stock underlying the Target Warrants (assuming a net exercise of any Target Preferred Warrant and the conversion of such shares of Target Preferred Stock issuable upon such exercise into shares of Target Common Stock), other than the number of shares of Target Common Stock attributable to the amount of Forfeited Consideration, (A) Parent shall distribute to the holder thereof from the Total Unvested Restricted Stock Consideration an amount equal to (I) the Forfeited Consideration held by Parent divided by (II) the Total Target Common Stock minus the number of shares of Target Common Stock attributable to the amount of Forfeited Consideration and (B) the remainder of the Forfeited Consideration shall be distributed to the extent provided in § 2(e)(iv).

(e) Lost, Stolen or Destroyed Certificates. Subject to § 3(a), § 3(b), § 3(c) and § 3(d), in the event that any Certificates shall have been lost, stolen or destroyed, in respect of such lost,

stolen or destroyed Certificates, the holder shall deliver an affidavit of that fact; provided, however, that Parent may, in its sole and absolute discretion and as a condition precedent to the payment thereof, require the owner of such lost, stolen or destroyed Certificate to deliver a bond in an amount equal to the Per Share Merger Consideration as indemnity against any Claim that may be made against Parent with respect to the Certificates alleged to have been lost, stolen or destroyed.

(f) Appraisal Rights; Dissenting Shares. Subject to § 8(a)(iii) hereof, any issued and outstanding shares of Target Stock held by a Person who has properly demanded an appraisal and perfected the right to dissent under the DGCL and who has not effectively withdrawn or lost such rights as of the Effective Time (the “Dissenting Shares”) shall not be converted into or represent the right to receive the Per Share Merger Consideration and the holders thereof shall be entitled only to such rights as are granted by the DGCL in accordance with the terms of the DGCL. The Target shall give Parent prompt notice upon receipt by the Target of any such written demands for payment of the fair value of such shares of Target Stock and of withdrawals of such demands and any other instruments provided pursuant to the DGCL (any stockholder duly making such demands being hereafter called a “Dissenting Stockholder”). Any payments made in respect of Dissenting Shares shall be made by Parent. If any Dissenting Stockholder shall effectively withdraw or lose (through failure to perfect or otherwise) his or its right to such payment at or prior to the Effective Time, each of such holder’s shares of Target Stock shall be converted into a right to receive the Per Share Merger Consideration in accordance with § 3(d)(i) or § 3(d)(ii), as applicable.

(g) No Further Ownership Rights in Target Capital Stock. The Total Merger Consideration (less any amount returned to Parent from the Escrow Amount for Indemnification) distributed to the Target Stockholders by the Exchange Agent shall be deemed to have been issued in full payment and satisfaction of all rights pertaining to the Target capital stock. At the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of capital stock of the Target which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and converted into the right to receive an amount equal to the product of (i) the Per Share Merger Consideration and (ii) the number of shares represented by such Certificate as provided in this § 3, except as otherwise provided by this Agreement or by law.

(h) Target Stockholder Representative.

(i) The adoption of this Agreement by the Target Stockholders by vote at a meeting of such Stockholders or by written consent shall constitute the approval of ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ as the “Target Stockholder Representative” and, as such, shall authorize ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ to serve as and have all powers as agent and attorney-in-fact of each Target Stockholder, for and on behalf of such Target Stockholders for purposes of this Agreement: to give and receive notices and communications; to have authority to agree to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to any disputes involving any claims for indemnification made by Parent; to sign receipts, consents, or other documents and to effect the transactions contemplated hereby; and to take all actions necessary or appropriate in the judgment of

Notice or communications to or from any Target Stockholder Representative shall constitute notice to or from each of the Target Stockholders.

(iii) The Target Stockholder Representative shall not be liable for any action taken or not taken as a Target Stockholder Representative in the absence of such Target Stockholder Representative’s gross negligence, fraud or willful misconduct. No bond shall be required of the Target Stockholder Representative, and the Target Stockholder Representative shall not receive compensation for his services.

(iv) A decision, act, consent or instruction of the Target Stockholder Representative shall constitute a decision of all the Target Stockholders, and shall be final, binding and conclusive upon each of the Target Stockholders, and Parent, Merger Sub, Surviving Corporation, and the Target may rely upon any decision, act, consent or instruction of the Target Stockholder Representative as being the decision, act, consent or instruction of each and all of the Target Stockholders. Parent, Merger Sub and Surviving Corporation are relieved from any Liability to any Target Stockholder or any other Person for any acts done by them in accordance with such decision, act, consent or instruction.

(v) The Target Stockholders agree to share on a pro rata basis and to reimburse Target Stockholder Representative for, the cost of any attorney, accountant or other advisors retained by the Target Stockholder Representative in connection with any action taken or not taken as a Target Stockholder Representative, and other reasonable expenses incurred by the Target Stockholder Representative, pursuant to the authorization granted in this §3(h), and neither Parent nor Surviving Corporation shall be responsible for any such expenses except to the extent such expenses are rightfully the responsibility of Parent or the Surviving Corporation in accordance with § 12(j)(i) of this Agreement.

(B) The Target and its Subsidiaries, and each of their respective officers and directors shall not, and shall cause their respective representatives (including, without limitation, investment bankers, attorneys and accountants) not to, directly or indirectly, through any officer, director, agent or otherwise, enter into, solicit, initiate, conduct or continue any discussions or negotiations with, or knowingly encourage or respond to any inquiries or proposals by, or provide any information to, or otherwise cooperate in any other way with, any Person or group of Persons, other than Parent, with respect to any inquiry or proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal.

The Target and each of its Subsidiaries shall immediately cease and cause its Affiliates to cease any and all existing activities, discussions or negotiations with any parties (other than Merger Sub or Parent) conducted heretofore with respect to any Acquisition Proposal, and shall use its commercially reasonable efforts to cause any such parties in possession of confidential information about the Target that was furnished by or on behalf of the Target in connection with such Acquisition Proposal to return or destroy all such information in the possession of any such party or its representatives.

shall have executed a confidentiality agreement (which agreement shall be provided to Parent for informational purposes) with terms no less favorable to the Target, in all material respects, to those contained in the Confidentiality Agreement.

(C) The Target and its Subsidiaries, and their respective officers and directors shall (I) promptly (but in any event within one day) notify Parent (orally and in writing) of the receipt of any request for information, Acquisition Proposal or any inquiry or proposal that may reasonably be expected to lead to an Acquisition Proposal, or any inquiry regarding the making of an Acquisition Proposal, the terms and conditions of any such request, inquiry, proposal, or Acquisition Proposal, and the identity of the prospective purchaser, (II) promptly provide Parent with a copy of any such offer, if written, or a written summary of such offer, if not in writing, and (III) shall keep Parent fully informed of the status and material details (including amendments and proposed amendments) of any such request, inquiry, proposal, or Acquisition Proposal. Prior to taking any of the actions referred to in § 6(a)(xxiv)(B), the Board of Directors of the Target shall promptly (but in any event within one day) notify Parent orally and in writing of any action it proposes to take with respect to such Acquisition Proposal. After taking any such action, the Board of Directors of the Target shall promptly advise Parent orally and in writing of the status of such action as developments arise or as requested by Parent. Without limiting the foregoing, at least five (5) days prior to taking any of the actions referred to in § 6(a)(xxiv)(D), the Board of Directors of the Target shall notify Parent of any such action it proposes to take and, during such five (5) day period, the Board of Directors of the Target shall negotiate in good faith with Parent with respect to any revised proposal to acquire the Target Stock that Parent may make prior to or during such five (5) day period.

(D) From and after the date hereof until the earlier of the Effective Time and the termination of this Agreement pursuant to § 11, if the Board of Directors of the Target is entitled to furnish information to, or engage in discussions or negotiations with, any Person pursuant to § 6(a)(xxiv)(B), the Board of Directors of the Target may terminate this Agreement in respect of any Acquisition Proposal pursuant to the termination provisions set forth in § 11(a)(viii) hereof if (I) such Acquisition Proposal constitutes a Superior Proposal, (II) such Superior Proposal did not result from a breach by the Target of this § 6(a)(xxiv), (III) the Board of Directors of the Target shall have determined in good faith after consultation with independent outside legal counsel and taking into account any changes to the terms of the Merger proposed by Parent, that such action is necessary for the Board of Directors of the Target to comply with its fiduciary duties to the stockholders of the Target under applicable laws, (IV) such Adverse Recommendation is made after the five day period referred to in § 6(a)(xxiv)(C) above and prior to the adoption of this Agreement either at a special meeting of the stockholders of the Target or pursuant to a written consent of the stockholders of the Target and (V) the Target makes all payments required by § 12(j)(ii) hereof.

advisable to consummate the transactions contemplated by this Agreement and each Party will keep the other Party apprised of the status of matters relating to completion of the transactions contemplated hereby.

(xxvii) Access to Financial and Operation Information.

(d) [INTENTIONALLY OMITTED.]

(e) Matters Involving Third Parties.

(i) If any third party shall notify any Party (the “Indemnified Party”) with respect to any matter (a “Third Party Claim”) which may give rise to a claim for indemnification against any other Party (the “Indemnifying Party”) under this § 9(e), then the Indemnified Party shall promptly notify each Indemnifying Party thereof in writing; provided, however, that no delay on the part of the Indemnified Party in notifying any Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is materially prejudiced thereby.

(ii) Any Indemnifying Party will have the right to defend the Indemnified Party against the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party so long as:

(A) the Indemnifying Party notifies the Indemnified Party in writing within fifteen (15) days after the Indemnified Party has given notice of the Third Party Claim that the Indemnifying Party will indemnify the Indemnified Party from and against the entirety of any Adverse Consequences the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by all elements of all or the portion of the Third Party Claim for which it is asserting its right to control such defense;

(B) if Parent or its Subsidiary is the Indemnified Party, the portions of the Third Party Claim with respect to which the Indemnifying Party is asserting its right to defend does not seek injunctive or other equitable relief that could affect an existing product or product development of Parent or any of its Subsidiaries (including the Surviving Corporation);

(D) the Indemnifying Party complies with its obligations set forth in § 9(f).

(iii) So long as the Indemnifying Party is conducting the defense of the Third Party Claim in accordance with § 9(e)(ii) above, (A) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (B) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (not to be withheld unreasonably), and (C) if the judgment or settlement would impose any material restriction upon the Indemnified Party or the operation of the business of the Indemnified Party, the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party.

(iv) In the event any of the conditions in § 9(e)(ii) above is or becomes unsatisfied, however, (A) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third Party Claim in any manner it reasonably may deem appropriate (upon consent from any Indemnifying Party in connection therewith, not to be unreasonably withheld), (B) the Indemnifying Party will reimburse the Indemnified Party promptly and periodically for the costs of defending against the Third Party Claim (including reasonable attorneys’ fees and expenses), and (C) the Indemnifying Party will remain responsible for any Adverse Consequences the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim to the fullest extent provided in this § 9.

(v) Each Party acknowledges and agrees that it shall not be entitled to seek indemnification from any other Party for any Third Party Claim without: (A) for any nonlitigation matter, giving notice of such Third Party Claim to such other Party in accordance with § 9(e)(ii)(A) above (including the proviso contained therein); or (B) for a litigation matter, (x) giving notice of such Third Party Claim to such other Party in accordance with § 9(e)(ii)(A) above (including the proviso contained therein) and (y) giving such other Party the opportunity to defend against such Third Party Claim in accordance with § 9(e)(ii) above. Parent may, in its sole discretion and without providing any notice, defend, handle and dispose of as it sees fit any Third Party Claim so long as it does not seek indemnification with respect to such Third Party Claim and such Third Party Claim does not include injunctive or equitable relief against the Target Stockholders. In addition, Parent may, in its sole discretion, assume the defense of, and handle and dispose of as it sees fit any Third Party Claim for which it has previously sought indemnification by providing notice of its intention to so defend, handle and dispose of such Third Party Claim and that it no longer shall seek indemnity with respect to such Third Party Claim (except for any amounts accrued and unpaid by the Target Stockholders prior to the date of such notice from Parent and such Third Party Claim does not include injunctive or equitable relief against the Target Stockholders). In the event that Parent provides such notice, the Target Stockholders shall promptly and reasonably cooperate with Parent in transferring the defense of such Third Party Claim.

(f) Satisfaction of Claims. The claims for indemnification pursuant to § 9(b) are referred to as “Parent Indemnity Claims.” Parent Indemnity Claims that are not in dispute by the Parties shall be satisfied by payment of cash or other immediately available funds from the Target Stockholders within ten (10) calendar days of delivery of notice by Parent or Merger Sub of the nature and amount of Parent Indemnity Claim. The claims for indemnification pursuant to § 9(c) are referred to as “Target Stockholder Indemnity Claims.” Target Stockholder Indemnity Claims that are not in dispute by the Parties shall be satisfied by payment of cash or other immediately available funds from Parent within ten (10) calendar days of delivery of notice by the Target Stockholder Representative of the nature and amount of the Target Stockholder Indemnity Claim.

(i) Notice of Asserted Liability. Promptly after Parent or the Target Stockholders become aware of any fact, condition or event that may give rise to an Adverse Consequence for which indemnification may be sought under this § 9, the party entitled to seek indemnification (“Indemnitee”) shall give notice thereof in the manner provided in this § 9(f)(i) (the “Claims Notice”) to the Indemnifying Party in accordance with § 12(f). The Claims Notice shall include a description in reasonable detail of any claim or the commencement (or threatened commencement) of any action, proceeding or investigation (an “Asserted Liability”) against Indemnitee, and shall indicate the amount (estimated, if necessary) of the Asserted Liability that has been or may be suffered by Indemnitee. Failure of Indemnitee to promptly give notice hereunder shall not affect rights to indemnification hereunder, except to the extent that Indemnifying Party demonstrates actual damage caused by such failure. Upon Indemnifying Party’s request,

Indemnitee shall provide Indemnifying Party with reasonable access to all books and records relating to the Asserted Liability, and to all employees or other Persons who have material information about such Asserted Liability, in order to allow Indemnifying Party to audit the status of such Asserted Liability and the payments that have been, or will be, made with respect thereto; provided that the Indemnifying Party shall refrain from unreasonably interfering with Indemnitee’s operations while the Indemnifying Party is conducting such audit.

(ii) Establishment of an Adverse Consequence. Indemnitee and the Indemnifying Party may agree in writing, at any time, as to the existence and amount of the Adverse Consequence, and, upon the execution of such agreement, the amount of such Adverse Consequence shall be deemed established. Additionally, except with respect to claims as described in § 9(e), if within ten (10) days after the giving of the written notice by Indemnitee in accordance with § 12(f) the Indemnifying Party does not provide written notice to Indemnitee in accordance with § 12(f) that the Indemnifying Party intends to contest the assertion by Indemnitee (such notice by the Indemnifying Party being hereinafter referred to as the “Contest Notice”), such assertion of the Indemnitees shall be deemed accepted and the amount of the Adverse Consequence shall be deemed established. However, in the event that a Contest Notice is given to Indemnitee within said 10-day period, for a period of not less than ten (10) days, the Parties shall seek in good faith to resolve in writing any differences they may have with respect to matters specified in the Contest Notice. If the Parties are unable to so resolve their differences after good faith negotiation, then either Parent or the Target Stockholder Representative may commence litigation or, upon written consent of Parent and the Target Stockholder Representative, binding arbitration to resolve the dispute.

(iii) Participation in Defense. Each party may participate, at its own expense, in the defense of any Asserted Liability in respect of which such party may have an indemnification obligation hereunder. If either party chooses to defend or participate in the defense of an Asserted Liability, it shall have the right to receive from the other party (subject to appropriate confidentiality provisions) any books, records or other documents within such party’s control that are necessary or appropriate for such defense.

(g) Payment for Adverse Consequences. The Indemnifying Party hereby agrees to pay the amount of established Adverse Consequences within fifteen (15) days after the establishment thereof. The amount of established Adverse Consequences shall be paid in cash. Any amounts not paid by the Indemnifying Party when due under this § 9 shall bear interest from and after the due date thereof until the date paid at a rate equal to the lesser of: (a) ten percent (10%) per annum; or (b) the highest legal rate permitted by applicable law. In addition, at the option of Indemnitee, Indemnitee may offset in good faith the amount of any established Adverse Consequences or any portion thereof that has not been paid by the Indemnifying Party to Indemnitee against any obligation Indemnitee may have to the Indemnifying Party.

(h) Further Limitations. Notwithstanding any other provision of this §9:

(i) No party will have any liability for indemnification under this § 9 with respect to the breach of any representation or warranty contained herein unless on or

before the date that such representation and warranty expires in accordance with § 9(a), the party seeking indemnification notifies such party of a claim specifying the factual basis of that claim in reasonable detail in accordance with § 9(e) or § 9(f), as applicable.

(ii) The maximum aggregate amount for which the Target Stockholders shall be liable for Adverse Consequences relating to Parent Indemnity Claims pursuant to § 9(b)(ii) hereof shall be an amount no greater than fifteen percent (15%) of the Total Merger Consideration.

(iii) Parent shall not seek, or be entitled to, indemnification from the Target Preferred Stockholders pursuant to § 9(b)(ii) hereof until the aggregate amount of Adverse Consequences relating to Parent Indemnity Claims incurred or suffered by Parent Indemnitees exceeds One Hundred Twenty Five Thousand Dollars ($125,000) (the “Deductible”), and once Parent Indemnitees have incurred or suffered aggregate Adverse Consequences relating to Parent Indemnity Claims exceeding the Deductible, Parent shall be entitled to indemnification only for the amount of all Adverse Consequences relating to Parent Indemnity Claims in excess of the amount of the Deductible (subject to the limitations set forth in this § 9(h)).

(iv) In no event will the Target Stockholders or Parent be liable for any claims alleging consequential damages incurred or suffered by an Indemnified Party, as applicable, with respect to this Agreement or the transactions contemplated hereby.

(i) Sole Remedy for Breaches of Representations and Warranties. Except for claims for fraud, bad faith or willful malfeasance, the indemnification provided in this § 9 shall be the sole and exclusive remedy after the Closing Date for damages available to Parent and Merger Sub for breach of any of the representations or warranties, covenants or agreements contained in this Agreement. Parent and Merger Sub expressly agree that with respect to claims made pursuant to this § 9, it shall first seek recovery against the Escrow Amount for Indemnification.

10. Tax Matters. The following provision shall govern the allocation of responsibility as between Parent and Target Stockholders for certain Tax matters following the Closing Date:

(a) Certain Taxes. All transfer, documentary, sales, use, stamp, registration and other Taxes and fees incurred in connection with this Agreement and the Merger, shall be paid by Parent when due.

(b) Tax Returns. Parent shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Target and its Subsidiaries which are filed after the Closing Date until December 31, 2005. Parent shall permit the Target Stockholder Representative to review and comment on each such Tax Return described in the preceding sentence prior to filing and shall make such revisions to such Tax Returns as are reasonably requested by the Target Stockholder Representative.

(c) Straddle Periods. For purposes of this Agreement, in the case of any Taxes of the Target or any of its Subsidiaries that are payable with respect to any Tax period that begins before and ends after the Closing Date (a “Straddle Period”), the portion of any such Taxes for taxable periods or portions thereof ending on or before the Closing Date shall: (i) in the case of

Taxes that are either (x) based upon or related to income or receipts, or (y) imposed in connection with any sale, transfer or assignment or any deemed sale, transfer or assignment of property (real or personal, tangible or intangible), be deemed equal to the amount that would be payable if the Tax year or period ended on the Closing Date; and (ii) in the case of Taxes (other than those described in clause (i) above) that are imposed on a periodic basis with respect to the business or assets of the Target or its Subsidiaries or otherwise measured by the level of any item, be deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding Tax period) multiplied by a fraction the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period. For purposes of clause (i) of the preceding sentence, any exemption, deduction, credit or other item (including, without limitation, the effect of any graduated rates of tax) that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis determined by multiplying the total amount of such item allocated to the Straddle Period times a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period. In the case of any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, any amount thereof required to be allocated under this § 10(c) shall be computed by reference to the level of such items on the Closing Date. All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with past practice of the Target and its Subsidiaries. The parties hereto will, to the extent permitted by applicable law, elect with the relevant Tax authority to treat a portion of any Straddle Period as a short taxable period ending as of the close of business on the day prior to the Closing Date. With respect to Tax Returns that are required to be filed by or with respect to the Target or any of its Subsidiaries for Straddle Periods (“Straddle Returns”), such Straddle Returns shall be prepared in a manner consistent with past practice. Parent shall notify the Target Stockholder Representative of amounts due from the Target Stockholders, if any, in respect of any Straddle Return no later than ten (10) Business Days prior to the date on which such Straddle Return is due, and, upon such notice, the Target Stockholder Representative shall direct the Escrow Agent to remit such payment to the extent of any remaining portion of the Escrow Amount for Indemnification to Parent. Parent shall deliver any Straddle Return to the Target Stockholder Representative for its review at least thirty (30) days prior to the date on which such Tax Return is required to be filed. If the Target Stockholder Representative disputes any item on such Tax Return, the Target Stockholder Representative shall notify Parent of such disputed item (or items) and the basis for its objection. The parties shall act in good faith to resolve any such dispute prior to the date on which the relevant Tax Return is required to be filed. If the parties cannot resolve any disputed item, the item in question shall be resolved by the Independent Accounting Firm. The fees and expenses of the Independent Accounting Firm shall be borne by: (x) Parent in the event that the Independent Accounting Firm agrees with the Target Stockholder Representative’s claim as to the disputed item (or items) or (y) by the Target Stockholders in the event that the Independent Accounting Firm agrees with Parent’s claim as to the disputed item (or items) or (z) fifty percent (50%) by the Target Stockholders and fifty percent (50%) by Parent if the Independent Accounting Firm determines that the disputed item (or items) should be another amount. Any amounts payable by the Target Stockholders shall be paid from the Escrow Account for Indemnification. Neither Parent nor any of its Affiliates shall

(or cause or permit the Surviving Corporation or any of its Subsidiaries to) amend, refile or otherwise modify any Tax Return relating in whole or in part to the Target or any of its Subsidiaries with respect to any taxable periods or portions thereof ending on or before the Closing Date (or with respect to any Straddle Period) without the written consent of the Target Stockholder Representative, which consent may be withheld in the sole discretion of the Target Stockholder Representative.

(d) Cooperation on Tax Matters.

(i) After the Closing Date, Parent, the Target and the Target Stockholder Representative shall cooperate fully, as and to the extent reasonably requested by the other Parties, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon any other Party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

(ii) Parent and the Target further agree, upon request, to use their reasonable best efforts to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to this transaction).

(iii) Parent and the Target further agree, upon request, to provide the other Parties with all information that such Party may be required to report pursuant to Section 6043 of the Code and all Treasury Regulations promulgated thereunder.

(e) Tax Proceedings. After the Closing Date, in the case of any audit, examination, or other proceeding with respect to Taxes related to any pre-Closing period (“Tax Proceeding”) and for which the Target Stockholders are or may be partially or fully liable to Parent pursuant to this Agreement, Parent shall inform or cause the Target to inform the Target Stockholder Representative thereof in accordance with § 9(e)(i). The Target Stockholder Representative shall be entitled to defend and settle any Tax Proceeding in accordance with § 9(e); provided that, if the Tax Proceeding involves both issues for which the Target Stockholders are or may be liable and issues for which they are not liable, the Target Stockholder Representative shall not be entitled to defend or settle the issues for which the Target Stockholders are not liable.

(f) Retention of Documents. The Surviving Corporation agrees until the expiration of the statute of limitations to (i) retain all books and records with respect to Tax matters pertinent to the Surviving Corporation relating to any taxable period beginning before the Closing Date of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) give the Target Stockholder Representative reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the Target Stockholder Representative so requests, the Target shall allow the Target Stockholder Representative to take possession of such books and records.

(ix) by Parent or the Target if the Effective Time shall not have occurred on or before June 30, 2005; provided, however, that the right to terminate this Agreement pursuant to this § 11(a)(ix) shall not be available to any Party whose failure to fulfill, or breach of, any obligation under this Agreement has been the cause of, or resulted in, the failure of the Effective Time to occur on or before such date; or

12. Miscellaneous.

(a) Further Action/Tax Treatment. Parent, the Target and Target Stockholders agree to cooperate to ensure that no payments made by Parent and the Target, either individually or in combination, pursuant to the Merger will be deemed to be an excess parachute payment under either Code §§ 280G or 4999. Cooperation under this § 12(a) shall be defined to include sharing of calculations and data used to perform Code § 280G analysis and approval by both Parent and the Target of the disclosures that are made in connection with the vote of the Target Stockholders to be used in order to qualify for the exemption under Code § 280G(b)(5)(A)(ii).

Any Party may send any notice, request, demand, claim, or other communication hereunder to the intended recipient at the address set forth above using any other means (including personal delivery, expedited courier, messenger service, facsimile, telecopy, telex, ordinary mail, or electronic mail), but no such notice, request, demand, claim, or other communication shall be deemed to have been duly given unless and until it actually is received by the intended recipient. Any Party may change the address to which notices, requests, demands, claims, and other communications hereunder are to be delivered by giving the other Parties notice in the manner herein set forth.

(g) Governing Law. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

(h) Amendments, Extensions and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the Parties hereto. At any time prior to the Effective Time, the Parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (i) extend the time for the performance of, any of the obligations or other acts of the other Parties hereto, (ii) waive any breach or inaccuracy in the representations and warranties contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any of the agreements or conditions contained herein. Any agreement on, the part of a Party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. No delay on the part of any Party hereto in exercising, or failure to assert, any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any Party hereto of any right, power or privilege hereunder operate as a waiver of any other right, power or privilege hereunder, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power

or privilege hereunder. No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. Unless otherwise provided, the rights and remedies herein provided are cumulative and are not exclusive of any rights or remedies which the Parties hereto may otherwise have at law or in equity.

(i) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

(j) Expenses.

(i) In the event that the transactions contemplated by this Agreement are not consummated, each of the Parties will bear its own costs and expenses (including, without limitation, all legal, outside advisors’ and accounting fees and expenses) incurred in connection with this Agreement and the transactions contemplated hereby. In the event that the transactions contemplated by this Agreement are consummated, Parent shall pay all fees and expenses incurred by the Target and the Target Stockholders in connection with the transactions contemplated herein, including fees and expenses of attorneys and accountants, up to a maximum of Four Hundred Fifty Thousand Dollars ($450,000); provided, however, that all costs and expenses of the Target and the Target Stockholders (including, without limitation, all legal, outside advisors’ and accounting fees and expenses) in excess of Four Hundred Fifty Thousand Dollars ($450,000) incurred in connection with this Agreement and the transactions contemplated hereby shall be borne by the Target Stockholders and shall not become obligations of the Surviving Corporation or of Parent.

(ii) Notwithstanding anything in this Agreement to the contrary,

(A) if this Agreement is terminated either:

(I) by Parent pursuant to § 11(a)(vi), (vii) or (x), or

(II) by the Target pursuant to § 11(a)(viii) or (x), and

(B) within twelve (12) months after the date of this Agreement the Target either:

(I) enters into a merger agreement, asset sale agreement or similar definitive agreement constituting or relating to any Acquisition Proposal, or

(II) otherwise agrees to any Acquisition Proposal,

then within two business days of the occurrence of either §12(j)(ii)(B)(I) or (II) above, the Target shall pay to Parent (as agent for itself and Merger Sub) the Target Break Up

Fee (as defined below) plus Parent’s and Merger Sub’s reasonably incurred out-of-pocket fees and expenses incurred by Parent and Merger Sub, including all legal, outside advisors’ and accounting fees and expenses. “Break Up Fee” means cash in immediately available funds in an amount equal to One Million Five Hundred Thousand Dollars ($1,500,000).

(k) Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement. Any reference to any federal, state, local, or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The Parties intend that each representation, warranty, and covenant contained herein shall have independent significance. If any Party has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty, or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not breached shall not detract from or mitigate the fact that the Party is in breach of the first representation, warranty, or covenant.

(l) Incorporation of Confidentiality Agreement, Exhibits, Parent Disclosure Schedule and Target Disclosure Schedule. The Confidentiality Agreement, Exhibits, Parent Disclosure Schedule and Target Disclosure Schedule identified in this Agreement are incorporated herein by reference and made a part hereof.

(m) Specific Performance. Each of the Parties acknowledges and agrees that the other Parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each of the Parties agrees that the other Parties shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter (subject to the provisions set forth in § 12(n) below), in addition to any other remedy to which they may be entitled, at law or in equity.

(n) Submission to Jurisdiction. Each of the Parties submits to the exclusive jurisdiction of any state or federal court sitting in The City of New York, New York, in any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of the action or proceeding may be heard and determined in any such court. Each Party also agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the Parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other Party with respect thereto. Nothing in this § 12(n), however, shall affect the right of any Party to serve legal process in any other manner permitted by law or at equity.

(o) Counsel to Target. Each Target Stockholder acknowledges and agrees that ▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇ and ▇▇▇▇ LLP, counsel to the Target, has represented the interests

of the Target and not the individual interests of each Target Stockholder with respect to the transaction or transactions contemplated by this Agreement. Each Target Stockholder acknowledges that such stockholder has consulted with such stockholder’s own counsel, accountant and/or business advisor as to the legal, tax, investment and related matters with respect to the transaction or transactions contemplated by this Agreement.
