11.1.2. All liabilities and obligations of and claims against the Seller or the Assets or arising from the conduct of the Business of the Seller prior to the Closing Date, including all debts, liabilities and obligations of any nature, absolute or contingent, foreseen or unforeseen, which are attributable or chargeable to the ownership and operation of the Business of the Seller prior to the Closing Date, specifically including, without limiting the foregoing, liability for products sold, or services provided, by the Seller or any subsidiary of the Seller and all environmental liabilities;

11.1.3. All liabilities and obligations resulting from the termination of any employee of the Seller; and

11.1.4. All actions, suits, proceedings, demands, assessments, judgments, costs and expenses (including interest paid thereon and all reasonable attorneys’ fees incurred) incident to the foregoing.

11.2. The Purchaser shall indemnify and hold harmless the Seller, its successors and assignees, with respect to any damage, expense or loss suffered by any of them resulting from:

11.2.1. Any misrepresentation, breach of warranty or non-fulfillment of any covenant, undertaking or agreement on the part of the Purchaser under this Agreement or any misrepresentation in or omission from any certificate or other instrument furnished or to be furnished to the Seller hereunder; and

11.2.2. All actions, suits, proceedings, demand, assessments, judgments, costs and expenses (including interest paid thereon and all reasonable attorney fees incurred), incident to the foregoing.

11.3. Seller or Purchaser, as the case may be (“Indemnified Party”), shall give notice to the other (“Indemnifying Party”), as soon as possible after the Indemnified Party has actual knowledge of any claim as to which indemnification may be sought in the amount thereof, if known, and supply any other information in the possession of the Indemnified Party regarding such claim, and will permit the Indemnifying Party (at its expense) to assume the defense of any third party claim in any litigation resulting therefrom, provided that counsel for the Indemnifying Party who shall conduct the defense of such claim or litigation shall be reasonably satisfactory to the indemnified party, and provided further that the omission of the Indemnified Party to give the notice as provided

- 20 -

herein will not relieve the Indemnifying Party of its indemnification obligation hereunder except to the extent that the omission results in a failure of actual notice to Indemnifying Party and the Indemnifying Party is materially damaged as a result of the failure to give notice. The Indemnifying Party may settle or compromise any third party claim or litigation with the consent of the Indemnified Party which consent may not be unreasonably withheld. The Indemnified Party shall have the right at all times to participate in the defense, settlement, negotiations or litigation relating to any third party claim or demand at its own expense. In the event that the Indemnifying Party does not assume the defense of any matter as above provided, then the Indemnified Party shall have the right to defend any such third party claim or demand, and will be entitled to settle any such claim or demand in its discretion. In any event, the Indemnified Party will cooperate in the defense of any such action and the records of each party shall be available to the other with respect to such defense.

11.4. Indemnity obligations of the Indemnifying Party shall survive the applicable time period provided in Section 10 with respect to any claim made prior to the end of such period until the liability is finally determined.

11.5. Neither the Seller nor the Purchaser shall not have any liability for an indemnification claim under this Section 11, unless and until the aggregate adverse consequences associated with such claim exceed Five Thousand Dollars ($5,000) and then only for the amount which exceeds this threshold except this threshold shall not apply to any failure to pay the Purchase Price at Closing as required hereunder or to pay any liabilities assumed hereunder. The Seller’s and Purchaser’s indemnification obligations under this Section 11 shall in no event exceed the amount of the Purchase Price.

11.6. The Purchaser and the Seller acknowledge and agree that the foregoing indemnification provisions in this Section 11 shall be the exclusive remedy of the Purchaser with respect to the transactions contemplated by this Agreement (except in the event of actual fraud or intentional concealment on the part of the Seller in which event the indemnification provisions shall be in addition to any other remedies available at law or in equity).

11.7. In addition, if after completion of the arbitration proceedings in accordance with the provisions set forth in Section 14.8 below, the arbitrators determine that Purchaser has the right to be indemnified and held harmless under this Section 11, the Purchaser may offset all losses, claims, liabilities, obligations or expenses (including reasonable attorneys’ fees) incurred by it in relation thereto against any amounts due the Sellers as Royalties. The Purchaser shall exercise such right of offset by giving the Seller prior written notice thereof, which notice shall set forth the basis for such offset and the amount thereof.

11.8. To secure Seller’s indemnification obligations under this Section, Seller shall grant to Purchaser a third priority deed of trust (the “Deed of Trust”), in a form acceptable to Purchaser, encumbering the Office Property. Purchaser shall be responsible for recordation of the Deed of Trust and Purchaser and Seller shall pay equally any taxes or fees imposed in connection with such

- 21 -

recordation. The Purchaser shall execute any such document as is necessary to release the Deed of Trust of record on the earlier date of (i) the date on which the Seller conveys the Office Property to a bona-fide third party in an arms length transaction or (ii) the date which is nine months after the Closing.

12. Expenses of the Parties.

Except as specifically provided herein, all expenses incurred by or on behalf of the parties hereto including, without limitation, all fees and expenses of agents, representatives, counsel and accountants employed by the parties hereto in connection with the preparation of this Agreement and the consummation of the transactions contemplated by this Agreement shall be borne solely by the party who shall have incurred such expenses and the other party shall have no liability in respect thereof.

13. Termination.

13.1. This Agreement may be terminated by written notice given by either party as follows:

13.2. Each of Seller’s and Purchaser’s right to termination under this Section 13 is in addition to any other rights that they have under this Agreement or otherwise, and the exercise of a right of termination will not be an election of remedies. Notwithstanding the provisions of Section 13.1, Purchaser and Seller shall endeavor in good faith to close on or before sixty (60) days after the Feasibility Termination Date.

- 22 -

13.3. If either party terminates this Agreement pursuant to Section 13, all rights and obligations of the Parties hereunder shall terminate without any liability of any party to any other party (except for any liability of any party then committing willful default or willful breach); provided, however, that the confidentiality provisions contained herein shall survive termination. If any party terminates this Agreement other than as permitted by Section 13.1, the non-breaching party would suffer irreparable damage and therefore shall be entitled to specific performance of the terms hereof in addition to any other remedy at law or in equity.

14. Miscellaneous.

Harris, Thomas R. Reynolds, James H. Brennan, or Richard J. Freer.

14.3. This Agreement shall be governed by and construed and enforced in accordance with the laws of the Commonwealth of Virginia, without giving effect to the conflict of laws principles thereof. The section headings contained herein are for reference purposes only and shall not in any way affect the meaning or interpretation of this Agreement.

14.4. This Agreement may be amended, modified, superseded or canceled only by a written instrument executed by all of the parties hereto. Notice or knowledge of any matter shall not constitute a waiver of any representation or warranty with respect to such matter. The waiver by any party of any breach of any provision shall not be construed as a waiver of any other provision by such party. Each party shall have the right to waive fulfillment of a condition or covenant or compliance with a representation or warranty of which it is the beneficiary, but such waiver may be made only by written instrument executed by such party.

14.5. All understandings and agreements of the parties are merged into this Agreement and the instruments and agreements specifically referred to herein.

14.7. In the event any provision of this Agreement is deemed to be unenforceable, the remainder of this Agreement shall not be affected thereby and each provision hereof shall be valid and enforced to the fullest extent permitted by law.

14.8. Notwithstanding any provision of this Agreement to the contrary, upon the request of any party hereto (each, a “Party” and collectively, the “Parties”), any dispute, controversy or claim arising out of, relating to, or in connection with, this Agreement or any agreement executed in connection herewith or contemplated hereby, or the breach, termination, interpretation, or

- 24 -

validity hereof or thereof (hereinafter referred to as a “Dispute”), shall be finally resolved by mandatory and binding arbitration in accordance with the terms hereof. Any Party may bring an action in court to compel arbitration of any Dispute. Any Party who fails or refuses to submit any Dispute to binding arbitration following a lawful demand by the opposing Party shall bear all costs and expenses including reasonable attorneys’ fees incurred by the opposing Party in compelling arbitration of such Dispute. The arbitration shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association in effect at the time of the arbitration, except as they may be modified herein or by mutual agreement of the Parties. The seat of the arbitration shall be in Richmond, Virginia. The arbitration and this clause shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1 et seq. (the “Federal Arbitration Act”). The arbitrator shall award all reasonable and necessary costs (including the reasonable fees and expenses of counsel) incurred in conducting the arbitration to the prevailing Party in any such Dispute. The Parties expressly waive all rights whatsoever to file an appeal against or otherwise to challenge any award by the arbitrators hereunder; provided, that the foregoing shall not limit the rights of any Party to bring a proceeding in any applicable jurisdiction to confirm, enforce or enter judgment upon such award (and the rights of the other Party, if such proceeding is brought to contest such confirmation, enforcement or entry of judgment, but only to the extent permitted by the Federal Arbitration Act). No provision of, nor the exercise of any rights under this Agreement shall limit the right of any Party to apply for injunctive relief or similar equitable relief with respect to the enforcement of this Agreement or any agreement executed in connection herewith or contemplated hereby, and any such action shall not be deemed an election of remedies. Such rights can be exercised at any time except to the extent such action is contrary to a final award or decision in any arbitration proceeding. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof. The institution and maintenance of an action for injunctive relief or similar equitable relief shall not constitute a waiver of the right of any Party, including without limitation the plaintiff, to submit any Dispute to arbitration nor render inapplicable the compulsory arbitration provisions of this Agreement. In addition to the authority conferred on the arbitration tribunal by the rules specified above, the arbitration tribunal shall have the authority to order reasonable discovery, including the deposition of party witnesses and production of documents. The arbitral award shall be in writing, state the reasons for the award, and be final and binding on the Parties with no right of appeal. All statutes of limitations that would otherwise be applicable shall apply to any arbitration proceeding. No Party waives any attorney client privilege or any other protection against disclosure of confidential information by reason of anything contained in or done pursuant to or in connection with this Agreement. Each Party agrees to keep all Disputes and arbitration proceedings strictly confidential, except for disclosures of information to the Parties’ legal counsel or auditors or those required by applicable law. The arbitrators shall determine the matters in dispute in accordance with the substantive law of Virginia, without regard to conflict of law rules. The arbitration shall be conducted by three (3) arbitrators. The Party initiating arbitration (the “Claimant”) shall appoint its arbitrator in its request for arbitration (the “Request”).

- 25 -

The other Party (the “Respondent”) shall appoint its arbitrator within thirty (30) days after receipt of the Request and shall notify the Claimant of such appointment in writing. If the Respondent fails to appoint an arbitrator within such thirty (30) day period, the arbitrator named in the Request shall decide the controversy or claim as sole arbitrator. Otherwise, the two (2) arbitrators appointed by the Parties shall appoint a third (3rd) arbitrator within thirty (30) days after the Respondent has notified Claimant of the appointment of the Respondent’s arbitrator. When the third (3rd) arbitrator has accepted the appointment, the two (2) Party appointed arbitrators shall promptly notify the Parties of the appointment. If the two (2) arbitrators appointed by the parties fail to appoint a third (3rd) arbitrator or so to notify the Parties within the time period prescribed above, then the appointment of the third (3rd) arbitrator shall be made by the American Arbitration Association, which shall promptly notify the Parties of the appointment. The third (3rd) arbitrator shall act as Chair of the panel. This arbitration provision constitutes the entire agreement of the Parties with respect to its subject matter and supersedes all prior discussions, arrangements, negotiations and other communications on dispute resolution. This arbitration provision shall survive any termination, amendment, renewal, extension or expiration of this Agreement or any agreement executed in connection herewith or contemplated hereby unless the Parties otherwise expressly agree in writing. The obligation to arbitrate any dispute shall be binding upon the successors and assigns of each of the Parties.

14.9. In the event of any legal action or proceeding (including any arbitration proceeding) arising out of or related to this Agreement, or any related document, the prevailing party shall be entitled to recover from such losing party all of its reasonable costs and expenses incurred in connection with such proceeding, including, without limitation, court costs and reasonable attorneys’ fees and expert witness and consultation fees, incurred at either the trial or appellate levels.
