Except as set forth on Schedule 4.7 to this Agreement or as otherwise required by Law, the consummation of the transactions contemplated by this Agreement will not in and of itself (1) entitle any current or former employee of CACI or any Subsidiary to severance pay, unemployment compensation or any other similar payment, or (2) accelerate the time of payment or vesting or increase the amount of compensation due to any such employee or former employee.

Except as disclosed on Schedule 4.7 to this Agreement, no such Benefit Plan that is an employee welfare benefit plan (as defined in ERISA Section 3(1)) provides benefits to current or future retirees or current or future former employees and their dependents, except as required by the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, or applicable state continuation coverage law.

Except as would not impose a material liability on CACI, any Subsidiary or any Asset, or except as set forth on Schedule 4.7 to this Agreement, each Benefit Plan and all related trust or other agreements conform in form and operation to, and comply with, all applicable laws and regulations, including, without limitation, ERISA and the Code, and all reports or information relating to each such Benefit Plan required to be filed with any Governmental Entity or disclosed to participants has been timely filed and disclosed.

All Pension Benefit Guaranty Corporation premiums have been timely paid and, except as disclosed on Schedule 4.7 to this Agreement, the assets of any Benefit Plan which is a defined benefit plan are sufficient, as of the Closing Date, to fund all of the benefit liabilities of such Benefit Plan (determined on a plan termination basis) and there has occurred no reportable event with respect to any Benefit Plan which is subject to Title IV of ERISA.

Except as disclosed on Schedule 4.7 to this Agreement, no Benefit Plan, or the Tax deduction of any contributions thereto by CACI or any Subsidiary, is, to the knowledge of CACI, the subject of an audit by any Governmental Entity, and no litigation or asserted claims exist against CACI, any Subsidiary or any Benefit Plan or fiduciary with respect thereto, other than such benefit claims as are made in the normal operation of a Benefit Plan.

Authorization; Due Execution; No Conflicts.

This Agreement and each Related Agreement has been duly authorized by all necessary corporate action on the part of Compuware.

Compuware's execution, delivery and performance of this Agreement and the Related Agreements will not (1) constitute a breach or violation of (A) Compuware's Articles of Incorporation or Bylaws (B) any Law or (C) any material agreement, indenture, deed of trust, mortgage, loan agreement or other material instrument to which Compuware is a party or by which Compuware is bound; or (2) constitute a violation of any order, judgment or decree to which Compuware is a party or by which any of Compuware's assets are bound or affected; (3) require any consent, approval, authorization or permit of or from, or filing with or notification to, any Governmental Entity, except for filings pursuant to the HSR Act.

Disclosure. As of the date of this Agreement, to the knowledge of those employees of Compuware who have had direct involvement in the transactions contemplated by this Agreement, such employees are not aware of any matter that would entitle Compuware to indemnification from CACI or any Subsidiary pursuant to Article 9 of this Agreement.

Covenants Pending the Closing.

Conduct Through the Closing Date. [Intentionally omitted.]

Approvals and Consents. Each of CACI, the Subsidiaries and Compuware will use commercially reasonable efforts to obtain, in writing, all necessary governmental and third party approvals and consents required in order to authorize and approve this Agreement and the Related Agreements and to consummate the transactions contemplated by this Agreement.

Advice of Changes. [Intentionally omitted.]

Notice of Litigation [Intentionally omitted.]

Access to Properties and Records; Inspection. [Intentionally omitted.]

Supplemental Information and Documents. [Intentionally omitted.]

Filings. The parties will prepare and make any necessary notifications or filings under any federal, state, local, foreign or other laws, rules and regulations which may be required in connection with this Agreement and all of the transactions contemplated by this Agreement, as soon as possible, including all notifications and filings in respect of the Conditions (as defined in Section 7.3 of this Agreement). The parties will also provide all information necessary or desirable for making (or responding to any requests for further information following) any notification or filing made in respect of such Conditions.

Non-Disclosure Agreement. CACI, the Subsidiaries and Compuware agree that each party's non-disclosure obligations contained in any non-disclosure agreement signed by the parties will remain in full force and effect in accordance with the terms of such agreement.

Work in Progress. From and after the Closing, Compuware and the distributors of Compuware, including Compuware distributors resulting from distributor agreements assumed by Compuware pursuant to this Agreement (the "Distributors"), will have all communications (except as provided in the MODSIM License Agreement) with customers under any of the Contracts and with customers who are licensing, sublicensing or otherwise using any of the Proprietary Rights (collectively, "Customers"). Without limiting the generality of the foregoing, Compuware will, in the ordinary course of business, invoice Customers which were not invoiced prior to the Closing. For a period of 6 months after the Closing, CACI will refer, and will cause the Subsidiaries to refer, to Compuware all requests, communications and inquiries of any Customers. CACI will cooperate, and will cause the Subsidiaries to cooperate, with Compuware, and take such actions as Compuware reasonably requests and at Compuware's expense, to ensure that Customers send or deliver their payments directly to Compuware, or a Distributor if required by the applicable contract, and to ensure that payments from or on behalf of Customers which are improperly sent or delivered to CACI are not commingled with CACI's or any Subsidiary's assets. Each party (the "Recipient") will promptly remit to the other party (the "Entitled Party") all amounts paid to the Recipient but to which the Entitled Party has the right, including insurance proceeds. To the extent appropriate to accomplish the foregoing, the Recipient will endorse all checks and other instruments in favor of the Entitled Party and/or wire transfer such funds to the Entitled Party. The Recipient will provide the Entitled Party with such information as is necessary or reasonably requested to determine the amounts to which the Entitled Party is entitled. CACI will not take any action and will not permit any Subsidiary to take any action that could interfere with Compuware's relationship with any of the Customers.

Employee Matters.

On the Closing Date, Compuware shall offer employment commencing immediately after the Closing to each person employed by CACI or the Subsidiaries in the Business on the Closing Date (including without limitation persons on approved leaves of absence) and listed on Schedule 6.10 (each, an "Active Employee") on substantially the same terms as each employee's employment or leave of absence with CACI or the Subsidiaries immediately prior to the Closing Date, except health and welfare plans. CACI shall continue to assist Compuware in Compuware's efforts to employ the Active Employees, and CACI shall recommend to the Active Employees that such employees accept Compuware's offer of employment on substantially the same terms as described above.

Compuware's employee benefit and fringe benefit plans, programs, policies or arrangements ("Compuware's Welfare Plans") made available to Active Employees shall treat service by Active Employees with CACI or the Subsidiaries in the same manner as service with Compuware for purposes of eligibility to participate in such plans, programs, policies or arrangements.

Maintenance of Books and Records. Each of Compuware and CACI shall preserve or cause to be preserved until the sixth anniversary of the Closing Date all records possessed or to be possessed by such party relating to any of the Assets or Assumed Liabilities prior to the Closing Date. After the Closing Date, where there is a legitimate purpose (which shall be deemed to include tax filings of either party), such party shall provide the other party with access, upon prior, written reasonable request specifying the need therefor, during regular business hours, to (a) the officers and employees of such party and (b) the books of account and records of such party, but, in each case, only to the extent relating to the Assets or Assumed Liabilities prior to the Closing Date, and the other party and its representatives shall have the right to make copies of such books and records; provided, however, that the foregoing right of access shall not be exercisable in such a manner as to interfere unreasonably with the normal operations and business of such party; and further provided that, as to so much of such information as constitutes trade secrets or confidential business information of such party, the requesting party and its officers, directors and representatives will use due care to not disclose such information except (i) as required by law, (ii) with the prior written consent of such party, which consent shall not be unreasonably withheld, or (iii) where such information becomes available to the public generally, or becomes generally known to competitors of such party, through sources other than the requesting party, its affiliates or its officers, directors or representatives. Such records may nevertheless be destroyed by a party if such party sends to the other parties written notice of its intent to destroy records, specifying with particularity the contents of the records to be destroyed. Such records may then be destroyed after the 30th day after such notice is given unless another party objects to the destruction, in which case the party seeking to destroy the records shall deliver such records to the objecting party.

Conditions Precedent to the Parties' Obligations to Close.

Conditions Precedent of Compuware. Compuware's obligations under this Agreement are subject to the satisfaction at or before the Closing Date of each of the following conditions (the fulfillment of any of which may be waived in writing by Compuware):

All terms, covenants and conditions of this Agreement and the Related Agreements to be complied with or performed by CACI and the Subsidiaries prior to or on the Closing Date will have been fully complied with and performed by CACI and the Subsidiaries, as appropriate, including CACI's and the Subsidiaries' timely taking of all actions and delivery of all documents required to be taken and delivered by them under this Agreement and the Related Agreements.

The representations and warranties of CACI and the Subsidiaries contained in this Agreement will be true and correct at and as of the Closing Date as if made at and as of such time, with the same force and effect as if made at and as of the Closing Date, except for (1) changes contemplated and permitted by this Agreement and (2) those representations and warranties which address matters only as of a particular date which will have been true and correct as of such date.

There will not have been any Material Adverse Change.

All courts of law, Governmental Entities and other third parties, the consent, authorization or approval of which is necessary under any applicable law, rule, order or regulation or under any contract, commitment or other agreement of CACI or any Subsidiary, for the consummation of the transactions contemplated by this Agreement, will have consented to, authorized, permitted or approved such transactions, except where the failure to obtain such consent, authorization or approval will not have a Material Adverse Effect.

Compuware shall have received written consent in a form reasonably satisfactory to Compuware from all third parties whose consent is necessary for the assignment of any Contracts to be assigned and assumed by Compuware pursuant to the terms of this Agreement.

Conditions Precedent of CACI and the Subsidiaries. The obligations of CACI and the Subsidiaries under this Agreement are subject to the satisfaction at, or prior to, the Closing Date of the following conditions precedent (the fulfillment of any of which may be waived in writing by CACI):

All terms, covenants and conditions of this Agreement and the Related Agreements to be complied with or performed by Compuware prior to or on the Closing Date will have been fully complied with and performed by Compuware, as appropriate, including Compuware's timely taking of all actions and delivery of all documents required to be taken and delivered by it under this Agreement and the Related Agreements.

The representations, warranties, disclosures and statements of Compuware contained in this Agreement and the Related Agreements will be true and complete as of the date of this Agreement and on the Closing Date.

Mutual Condition Precedent. Unless waived in writing by each party, the consummation of this transaction will also be conditional upon the satisfaction of the following (Section 7.3(i) of this Agreement being the "Conditions"):

to the extent that any clearances under any relevant national merger control rules, anti-trust or similar legislation (including, but not limited to, the HSR Act) are required, such clearances are received or the relevant time limits or waiting periods (including any extensions) have expired or been terminated (as the case may be) without any decision having been made to investigate the Transaction further; and

no litigation will have been commenced or threatened by a third party to challenge the right of any party to consummate the transactions contemplated under this Agreement and the Related Agreements.

Default; Termination of Agreement.

Default. Compuware's, on the one hand, and CACI's and the Subsidiaries', on the other hand, obligations under this Agreement are of a special and unique character and Compuware's, on the one hand, or CACI's and the Subsidiaries', on the other hand, failure to perform its obligations will cause irreparable injury to the other party, the amount of which would be extremely difficult, if not impossible, to estimate or determine and which may not be adequately compensable by monetary damages alone. Therefore, the injured party will be entitled, as a matter of course, to an injunction, restraining order, writ of mandamus or other equitable relief from any court of competent jurisdiction, including specific performance, restraining any violation or threatened violation of any term of this Agreement or any Related Agreement, or requiring compliance with or performance of any obligation under this Agreement or such Related Agreement, by the violating party or parties, or such other persons as the court may order. The parties' rights under this Section 8.1 are cumulative and are in addition to the rights and remedies otherwise available to them under Section 8.2 below, any other provision of this Agreement and any other agreement or applicable law.

Indemnification by CACI. Upon the terms and subject to the conditions of this Article 9, CACI will indemnify and hold Compuware harmless against any Loss which may be incurred by Compuware as a result of:

any breach by CACI or any Subsidiary of any of its representations and warranties under Article 4 above or CACI's or any Subsidiary's breach of any agreements made in this Agreement or any Related Agreement or the Exhibits or Schedules to this Agreement or any Related Agreement;

any action, suit, proceeding, investigation, assessment or judgment relating to any of the matters indemnified against in this Section 9.1, including Fees and Costs (whether prior to or at trial or in appellate proceedings).

Indemnification by Compuware. Upon the terms and subject to the conditions of Article 9, Compuware will indemnify and hold CACI harmless against any Loss which may be incurred by CACI as a result of:

any breach by Compuware of any of Compuware's representations, warranties, covenants or agreements made in this Agreement or any Related Agreement or the Exhibits or Schedules to this Agreement or any Related Agreement, including without limitation, Compuware's obligations to pay and perform the Assumed Liabilities;

any action, suit, proceeding, assessment or judgment relating to any of the matters indemnified against in this Section 9.2, including Fees and Costs (whether prior to or at trial or in appellate proceedings).

Additional Indemnification by CACI. Upon the terms and subject to the conditions of this Article 9, CACI will indemnify and hold Compuware harmless against any Loss which may be incurred by Compuware as a result of:

any claim by Jess Marinez, or anyone acting on his behalf, that he is entitled to any amount based on the sale of the Assets to Compuware, notwithstanding the fact that any claim or the threat of any claim has been disclosed on the Schedules to this Agreement or otherwise;

any action, suit, proceeding, assessment or judgment relating to any of the matters indemnified against in this Section 9.3, including Fees and Costs (whether prior to or at trial or in appellate proceedings).

Whenever any claim is made for indemnification under this Article 9, the person claiming such indemnification (the "Claimant") will give notice to the party against whom indemnification is sought (the "Indemnifying Party") promptly after the Claimant has actual knowledge of any event which might give rise to a claim for indemnification under this Agreement; provided that if the Claimant receives a complaint, petition or any other pleading in connection with a claim which requires the filing of an answer or other responsive pleading, it will furnish the Indemnifying Party with a copy of such pleading as soon as possible after receipt.

Subject to the limitations on indemnification set forth in Section 9.6, the failure by the Claimant to give notice of a claim as required in Section 9.4(a) above or a delay in giving such notice will not affect the validity or amount of such claim and the indemnification obligations of the Indemnifying Party will remain in effect as to such claim, except to the extent that the Indemnifying Party has been prejudiced or adversely affected thereby.

If, after the amount of the claim of Loss is specified by Claimant, and Claimant gives notice with respect thereto to the Indemnifying Party (the "Claim Notice"), the Indemnifying Party objects to any such claim or amount set forth in the Claim Notice, it may give notice to Claimant advising Claimant of its objection within thirty (30) days of the Indemnifying Party's receipt of the Claim Notice. If no such notice is timely given by the Indemnifying Party to Claimant, then subject to the limitations on indemnification set forth in Section 9.6 Claimant will be entitled to payment from the Indemnifying Party pursuant to this Agreement and the Indemnity Escrow Agreement in the amount so specified. If the Indemnifying Party advises Claimant within such period that it objects to the claim, Claimant and the Indemnifying Party will promptly meet and use their reasonable efforts to settle the dispute in writing. If Claimant and the Indemnifying Party are unable to reach agreement within thirty (30) days after the Indemnifying Party objects to the claim, then either party may bring an action to determine the disputed portion of such claim of Loss, with the undisputed portion to be recovered pursuant to the Indemnity Escrow Agreement, if applicable, or this Agreement.

The giving of the notice by Compuware to CACI with respect to any particular claim in accordance with Section 9.4 within the period of survival of any representations or warranties will toll said survival period (but only with respect to such claim to the extent of the claim of Loss with respect to such claim) until any liability under said notice is finally resolved and determined.

If the facts giving rise to the right of indemnification under Sections 9.1, 9.2 or 9.3 above involve any actual or threatened claim or demand by any third party against the Claimant or any possible claim by the Claimant against any third party ("Third-Party Claim"), and if, within 20 days after receipt of notice of the claim, the Indemnifying Party gives the Claimant an agreement in writing, in form and substance reasonably satisfactory to the Claimant (which agreement is not intended to enlarge the scope of the Indemnifying Party's obligations under this Article 9), agreeing to indemnify and hold harmless Claimant from all costs and liability arising from such Third Party Claim, the Indemnifying Party may undertake, at its own expense, full responsibility for the defense or prosecution of such Third-Party Claim.

So long as the Indemnifying Party has assumed and is conducting the defense of the Third-Party Claim in accordance with this Section 9.5, 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 Claimant (which consent will not be unreasonably withheld, conditioned or delayed) unless the judgment or proposed settlement involves only the payment of money damages by the Indemnifying Party and does not impose an injunction or other equitable relief upon Claimant.

If the Indemnifying Party fails to deliver to the Claimant the agreement described in Section 9.5(a), (1) the Claimant will be entitled to defend or prosecute such Third-Party Claim with counsel of its own choice (the reasonable Fees and Costs of such defense or prosecution being indemnified under this Article 9), (2) the Indemnifying Party at its own expense may nevertheless participate with the Claimant in the defense or prosecution of such Third-Party Claim and any settlement negotiations with respect thereto, and (3) except as provided herein, the Claimant may settle the Third-Party Claim on such terms as it may choose.

An Indemnifying Party's defense or prosecution of, or participation in, a Third-Party Claim will not in any manner relieve the Indemnifying Party of its obligations to indemnify the Claimant under this Article 9. The Indemnifying Party and the Claimant will cooperate in good faith with each other in connection with the defense or settlement of any Third-Party Claim and will make available to each other all information necessary or useful to the defense or settlement of such matter.

The representations and warranties of CACI and the Subsidiaries set forth in this Agreement will survive only for a period of one calendar year after the Closing Date, and any claim for indemnification under Section 9.1 must be asserted by notice to CACI within one calendar year after the Closing Date, or the same will be null and void; provided, however, that the representations, warranties and covenants made by CACI and the Subsidiaries under Section 4.15 will survive until sixty days after the expiration of the applicable statutes of limitations (including any waivers or extensions) on assessment and collection of the Tax to which such representation, warranty or covenant relates. If any claims for indemnification with respect to Taxes have been made pursuant to Sections 9.1 and the same are still pending or unresolved at the expiration of the survival period, such claims will continue to be subject to the indemnification provisions of this Agreement.

Any covenant or agreement by the parties hereto which by its terms contemplates performance after the Closing Date will survive the Closing Date, including the obligations and liabilities of CACI under Section 9.3.

CACI will not be obligated to indemnify Compuware under Section 9.1 unless and until the aggregate of Losses for which indemnity is provided under such Section 9.1 reaches $250,000, in which event CACI will be obligated to indemnify Compuware for all applicable Losses in excess of the first $100,000 of all aggregate Losses; provided, however, that the indemnification threshold of $250,000 and the indemnification deductible of $100,000 will not apply to the indemnification obligations of Section 9.1 specifically relating to Taxes nor will any amounts paid in respect of Section 9.1 reduce such indemnification threshold or affect such indemnification deductible as the same may apply to any other claims for indemnification.

If Compuware has received payment from the Indemnity Escrow Fund with respect to Losses pursuant to Sections 9.1 specifically relating to Taxes or any Losses pursuant to Section 9.1 resulting from a breach of the representation and warranties in Sections 4.6 and 4.15 (or any other Tax related provision of this Agreement) above or any Losses pursuant to Section 9.3 (collectively, the "Tax, IP and General Losses") and, thereafter, Compuware has received or is entitled to receive indemnification for other Losses ("Other Losses"), which, in the aggregate together with the Tax, IP and General Losses, exceed the Indemnity Escrow Cap, Compuware will nonetheless be entitled to collect from, and pursue, CACI for payment of, and CACI will pay to Compuware, (1) any Losses pursuant to Section 9.1 arising under the indemnification obligation with respect to Sections 4.6 and 4.15 (or any other provision of this Agreement specifically regarding Taxes), and any Losses pursuant to Section 9.3, to the extent unpaid and (2) any Other Losses up to the amount of the Indemnity Escrow Cap.

Notwithstanding anything herein to the contrary, Losses will not include punitive damages. Notwithstanding the preceding sentence, Losses will include amounts recoverable or recovered from Compuware by a third party (which third party will not include an affiliate of Compuware) which constitute punitive damages. Notwithstanding anything herein to the contrary, Losses will not include "lost profits" or "lost revenues", unless "lost profits" or "lost revenues" are included in claims of third parties against Compuware. Notwithstanding the preceding sentence, for purposes of this Article 9, "lost profits" or "lost revenues" means a negative impact on future revenues or profits of Compuware arising as an indirect or secondary consequence of a breach of a representation, warranty, covenant or agreement but "lost profits" or "lost revenues" will be included in Losses to the extent they are the direct consequence of a breach of a representation, warranty or covenant.

The parties agree that any indemnification payment made by CACI under Sections 9.1 or 9.3 to Compuware is an adjustment to the Purchase Price, and they agree to consistently so treat any such payment on any Tax Return or claim for refund that they file, in any administrative or appeals procedure, judicial proceedings, or any other situation in which a characterization of such a payment is made.

Each party hereby acknowledges and agrees that, from and after the Closing Date, its sole and exclusive remedy with respect to any and all claims relating to the subject matter of this Agreement will be pursuant to the provisions set forth in this Article 9, and that, with respect to the rights of Compuware pursuant to this Article 9 and the Indemnity Escrow Agreement, recovery from the Indemnity Escrow Fund will be the sole and exclusive remedy of Compuware for all Losses arising out of any breach of any of the representations, warranties, covenants or other obligations given or made by CACI in this Agreement or the Schedules hereto, or any certificates or written instruments delivered in connection herewith, except as provided in Section 9.3 or Section 9.6(d), and except for any claims based on fraud and/or Tax, IP and General Losses, for which Losses will not be so limited. In furtherance of the foregoing, but subject to the exceptions set forth in the immediately proceeding sentence, each party hereby waives, from and after the Closing Date, to the fullest extent permitted under applicable law, any and all claims, rights and causes of action (other than claims of fraud and claims arising under this Article 9) it may have relating to the subject matter of this Agreement arising under or based upon any federal, state, local or foreign statute, law, ordinance, rule or regulation or otherwise.

In determining the obligation of CACI to indemnify Compuware pursuant to this Article 9 or the Indemnity Escrow Agreement, all references in the Agreement or in any certificates delivered in connection with this Agreement to the terms "material", "materiality", "Material Adverse Change", "Material Adverse Event" or variants thereof will be disregarded for the purpose of determining whether there has been any misrepresentation or breach of warranty, except for the representations and warranties contained in Section 4.16.

Notices. Any notice required or permitted to be given under this Agreement must be in writing and sent by recognized overnight courier (such as Airborne or Federal Express) or by certified or registered mail, postage prepaid, or delivered by hand, addressed as follows:

Addresses for notices may be changed by notice given pursuant to this Section 10.1. Notice will be deemed given on the date delivered if delivered by hand. Notice sent by recognized overnight courier will be deemed given on the business day following delivery to such recognized overnight courier. Notice mailed as provided herein will be deemed given on the third (3^rd) business day following the date so mailed.

No Waiver. No waiver of any breach of any provision of this Agreement will be deemed a waiver of any preceding or succeeding breach or of any other provision of this Agreement. No extension of time for performance of any obligations or acts will be deemed an extension of the time for performance of any other obligations or acts.

Successors and Assigns. This Agreement will bind and inure to the benefit of the parties and their successors and assigns; provided that (i) CACI will not, and will not permit any Subsidiary to, assign this Agreement, any Related Agreement or any rights under this Agreement or any Related Agreement to any other person without the prior written consent of Compuware and (ii) Compuware will have the right to assign this Agreement and the Related Agreements to any direct or indirect wholly-owned subsidiary of Compuware.

Severability. The provisions of this Agreement will be deemed severable, and if any provision or part of this Agreement is held illegal, void or invalid under applicable Laws, such provision or part may be changed to the extent reasonably necessary to make the provision or part, as so changed, legal, valid and binding. If any provision of this Agreement is held illegal, void or invalid in its entirety, the remaining provisions of this Agreement will not in any way be affected or impaired but will remain binding in accordance with their terms.

This Agreement, the Related Agreements and the Schedules and the Exhibits attached to this Agreement and the Related Agreements contain the entire agreement of the parties with respect to the transactions contemplated by this Agreement and the Related Agreements, and no representations or warranties made by any party or its representatives, whether made orally or in writing, may be relied on unless set forth in this Agreement, the Related Agreements or in the Exhibits and Schedules to this Agreement and the Related Agreements and no representation or warranty made prior to the date of this Agreement by any party will survive the execution and delivery of this Agreement.

Subject to applicable law, at any time prior to the consummation of the transactions contemplated by this Agreement, CACI, the Subsidiaries and Compuware may, by action authorized by their respective Boards of Directors, (1) mutually amend this Agreement, (2) extend the time for the performance of any of the obligations or other acts of any other person or entity, (3) waive any inaccuracies in the representations or warranties contained in the Agreement, or (4) waive compliance with any of the agreements or conditions contained herein. This Agreement may not be amended except by a writing signed by all of the parties by persons authorized to execute such writing. Any agreement of a party to any extension or waiver will be valid only if set forth in a writing signed on behalf of such party by a person authorized to execute such writing, but any waiver or failure to insist on strict compliance with any obligation, covenant, agreement or condition will not operate as a waiver of or estoppel with respect to, any subsequent or other failure.

Cost of Litigation. If any party breaches this Agreement or any Related Agreement and if counsel is employed to enforce this Agreement or a Related Agreement, the successful party will be entitled to Fees and Costs associated with such enforcement, subject to the limits on indemnification set forth in Section 9.5.

This Agreement and the Related Agreements are being entered into among competent and experienced business persons, represented by counsel, and have been reviewed by the parties and their counsel. Therefore, any ambiguous language in this Agreement or any Related Agreement will not necessarily be construed against any particular party as the drafter of such language. The headings contained in this Agreement are solely for the purposes of reference, are not part of the agreement of the parties and will not in any way affect the meaning or interpretation of this Agreement.

Any statement under this Agreement made "to the knowledge" of a party will be deemed to have been made to the actual knowledge of such party. A statement under this Agreement made to the knowledge of CACI or any of CACI Products, CACI Development or CACI California means to the actual knowledge Dr. J.P. London, Stephen L. Waechter, Joseph Lenz and Peter MacDonald.

Unless the context of this Agreement otherwise requires: (1) words of any gender include each other gender; (2) words using the singular or plural number also include the plural or singular number, respectively; (3) the terms "hereof", "herein", "hereby", "hereto" and similar words refer to this entire Agreement and not any particular Article, Section, Clause, Exhibit, Appendix or Schedule or any other subdivision of this Agreement; (4) references to "Article", "Section", "Clause", "Exhibit", "Appendix" or "Schedule" are to the Articles, Sections, Clauses, Exhibits, Appendices and Schedules, respectively, of this Agreement; (5) the words "include" or "including" will be deemed to be followed by "without limitation" or "but not limited to" whether or not they are followed by such phrases or words of like import; and (6) references to "this Agreement" or any other agreement or document will be construed as a reference to such agreement or document as amended, modified or supplemented and in effect from time to time and will include a reference to any document which amends, modifies or supplements it, or is entered into, made or given pursuant to or in accordance with its terms. All accounting terms used herein and not expressly defined herein will have the meanings given to them under United States generally accepted accounting principles as in effect on the Closing Date.

Disclosure of any item or information in a Schedule is not an admission that such item or information is material or is of a nature that would cause a Material Adverse Effect with respect to any person or entity. The disclosure of one item in a Schedule will not by inference suggest that any other item not so disclosed is material.

Counterparts. This Agreement may be executed in counterparts, each of which, when taken together, will be deemed an original of this Agreement.

This Agreement and any dispute arising hereunder or related hereto will be construed in accordance with and governed by the laws of the State of Michigan, without giving effect to the choice of law provisions thereof.

Any litigation based hereon, or arising out of, under, or in connection with this Agreement will be brought and maintained exclusively in the courts of the State of Michigan or in the United States District Court for the Eastern District of Michigan. Each party to this Agreement hereby expressly and irrevocably submits to the jurisdiction of the courts of the State of Michigan and of the United States District Court for the Eastern District of Michigan for the purpose of any such litigation as set forth in the preceding sentence. Each party to this Agreement further irrevocably consents to the service of process by registered mail, postage prepaid, or by personal service within or without the State of Michigan.

Each party to this Agreement hereby expressly and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such litigation brought in any such court referred to above and any claim that any such litigation has been brought in an inconvenient forum. To the extent that any party to this Agreement has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice or otherwise) such party hereby irrevocably waives such immunity in respect of its obligations under this Agreement.

Expenses. Each party will bear its own expenses (including, without limitation, interest and penalties levied under tax laws) in connection with the transactions contemplated by this Agreement, including any taxes resulting from the transactions contemplated by this Agreement and the costs of their respective brokers, financial advisors, attorneys and accountants, regardless of whether any of the transactions contemplated by this Agreement are consummated.
