     11.7 Adjustments to the Purchase Price. Purchaser and Seller agree to treat any amounts payable after the Closing by Seller to Purchaser (or by Purchaser to the Seller) pursuant to this Agreement as an adjustment to the Purchase Price, unless a final determination by the appropriate taxing authority or court causes such payment not to be treated as an adjustment to the Purchase Price for Tax purposes.

     11.8 Net Worth of Seller. During the period from the Closing Date until the day and year when the representations and warranties of the Seller expire in accordance with Section 13.1 hereof, Seller will have and retain a Net Worth equal to no less than twice the amount of the Cap.

In the event the Indemnifying Party undertakes to defend any such Third-Party Claim, the Indemnifying Party shall promptly provide the Indemnified Party with copies of all pleadings and filings pertinent to the Third-Party Claim.

     13.5.3 Notwithstanding the foregoing provisions, the Indemnifying Party may not defend, compromise or otherwise control the settlement of a Third-Party Claim which (i) involves any remedy other than a pure monetary resolution, including, without limitation, injunctive relief against the Indemnified Party or requires the Indemnified Party to enter into a consent decree or (ii) may, in the Indemnified Party’s reasonable judgment, exceed the aggregate amount of the Indemnifying Party’s then current indemnity obligations to the Indemnified Party.

     13.5.4 If prior to (i) the Indemnified Party giving notice to the Indemnifying Party of a Third-Party Claim or (ii) the expiration of the Indemnity Acknowledgement Period, the Indemnified Party takes any action with respect to a Third-Party Claim, the Indemnifying Party shall not be relieved of its indemnification obligations unless the Indemnifying Party is prejudiced by any of the Indemnified Party’s actions and then only to the extent of such prejudice and only with respect to such Indemnified Party undertaking such actions.

     13.5.4 If the Indemnifying Party (i) fails to give written notice to the Indemnified Party within the Indemnity Acknowledgement Period of the Indemnifying Party’s intention to defend such Third-Party Claim at its own expense and acknowledging its obligation to indemnify the Indemnified Party against such claim, or (ii) fails to defend diligently and continuously a Third-Party Claim against the Indemnified Party, or (iii) is precluded from defending a Third-Party Claim pursuant to Section 13.5.3 above, the Indemnified Party shall have the right to compromise or defend such Third-Party Claim through counsel of its own choosing, but for the account and at the expense of the Indemnifying Party, subject to any applicable limitation on indemnification set forth in Section 13.3. The Indemnified Party’s rights set forth herein to compromise or defend any such claims shall be in addition to, and not mutually exclusive of, any such right the Indemnified Party may have at law or in equity or under any applicable statutes. In the event that the Indemnified Party is defending such a Third-Party Claim, the Indemnified Party shall upon request from the Indemnifying Party, promptly provide the Indemnifying Party with copies of all pleadings and filings pertinent to the Third-Party Claim and shall permit the Indemnifying Party’s counsel, at the Indemnifying Party’s expense, to participate in, but not control, the defense of such claim. The Indemnifying Party shall have the right to assume the defense of the claim at any time prior to settlement, provided that the Indemnifying Party (i) gives written notice of its intent to defend the claim on behalf of the Indemnified Party, (ii) acknowledges its obligation to indemnify the Indemnified Party against such Third-Party Claim, and (iii) reimburses the Indemnified Party for all of the Indemnified Party’s out-of-pocket costs incurred to date in conjunction with such claims (including reasonable attorneys’ fees and litigation expenses).

     13.4.6 Failure of an Indemnified Party to reasonably cooperate with the Indemnifying Party with respect to a Third-Party Claim shall mitigate the obligation to indemnify such Third-Party Claim to the extent that the Indemnifying Party shall have been actually and materially prejudiced as a result of such failure to reasonably cooperate. In addition, the obligation in connection with any Third-Party Claim shall be mitigated to the extent that the Indemnifying Party shall have been actually and materially prejudiced as a result of the gross negligence or willful misconduct of an Indemnified Party.

     13.4.7 If an Indemnifying Party willfully and unjustifiably fails to indemnify against a Third-Party Claim, the Indemnified Party shall be entitled to recover reasonable legal fees and expenses of enforcing this Section 13.4.

     13.5 Payment of Indemnification Obligations. Each Party shall promptly pay to any Indemnified Party the amount of all damages, losses, deficiencies, liabilities, costs, expenses, claims and other obligations to which the foregoing provisions of this Article XIII relates together with interest thereon from the date of assertion of such Claims at the prime rate in effect from time to time as announced by PNC Bank, National Association.

     13.6 Other Remedies. The indemnification provided in this Article XIII shall be the sole and exclusive financial remedy of any Indemnified Party following the Closing for any

inaccuracy or breach of any representation or warranty, agreements and covenants made by the Indemnifying Party in this Agreement with respect to which indemnification is provided in this Article XIII regardless of whether the Indemnified Party’s claim for recovering damages or other amounts is based in contract or tort or otherwise. Notwithstanding the foregoing, it is expressly understood and agreed that nothing contained herein shall be deemed to waive or limit the Parties’ rights to obtain non-financial equitable relief including, without limitation, the right to obtain one or more temporary or permanent injunctions. In the event that the Indemnifying Party is required to indemnify the Indemnified Parties pursuant to the requirements of this Agreement, the Indemnifying Party shall be entitled to recover such indemnity payments from unrelated third parties (including, without limitation, manufacturers, vendors and other suppliers, but specifically excluding the Indemnified Parties’ insurers).

     13.7 Dispute Resolution.

     13.7.1 Disputes. Any disagreement, dispute, controversy or claim arising out of or relating to this Agreement or the interpretation hereof or any arrangements relating hereto or contemplated herein or the breach or termination hereof, other than a dispute to be determined in accordance with Section 11.3 (each, individually, a “Dispute”), shall be resolved and settled exclusively and finally pursuant to the terms of this Section 13.7.

     13.7.2 Notice of Claim. In the event of a Dispute among Foster, Seller and Purchaser, any such party (the “Claimant”) may initiate the Dispute resolution procedures of this Section 13.7 by providing written notice (the “Notice of Claim”) to the other parties (the “Respondent”) identifying the Dispute and stating the desire to resolve the Dispute pursuant to the provisions of this Section. Insofar as is practicable, any documentation that supports the Claimant’s Notice of Claim shall be included with said Notice of Claim. Within fifteen (15) days after receiving the Notice of Claim, Respondent will respond in writing by stating its position and setting forth a proposed resolution of the Dispute. Insofar as is practicable, any documentation that supports the Respondent’s defense shall be included with such response. If Claimant and Respondent are not able to resolve the Dispute promptly thereafter, then the parties shall proceed in accordance with the provisions of Section 13.7.3 hereof.

     13.7.3 Internal Resolution. In the event a Dispute is not resolved pursuant to Section 13.7.2 hereof, then each party shall promptly nominate a senior officer of its management to meet to resolve the Dispute.

If the parties have not resolved the Dispute within forty-five (45) days after the date of the Notice of Claim, then any party may initiate arbitration of the Dispute pursuant to either Section 13.7.5 or 13.7.6 hereof by notifying the other party in writing that arbitration of the Dispute under Section 13.7.5 or 13.7.6 is demanded (the “Demand for Arbitration”). Foster, Seller and Purchaser agree to be bound by the results of the arbitration, and judgment upon the award so rendered may be entered and enforced in any court of competent jurisdiction. The forum of such arbitration shall be Pittsburgh, Pennsylvania to the exclusion of all other jurisdictions. Foster, Purchaser and Seller agree and consent to the jurisdiction of the courts of the Commonwealth of Pennsylvania situate in Allegheny County, Pennsylvania or the federal courts situated in the Western

District of Pennsylvania for the purpose of enforcing this Section 13.7 and for the purpose of confirming an award and entering judgment upon said award, and Foster, Purchaser and Seller further waive all objections to jurisdiction and venue in any such courts.

     13.7.5 Minor Disputes. If the amount in controversy is less than or equal to $500,000 then the parties shall, within thirty (30) days after the date of the Demand for Arbitration, select, by mutual agreement, a single arbitrator to hear and determine the dispute. In the event that the parties cannot agree upon the selection of a single arbitrator, the parties agree that the American Arbitration Association (“AAA”) located in Pittsburgh, Pennsylvania will select an independent Commercial Litigation Attorney to serve as arbitrator. The term “Commercial Litigation Attorney” shall mean a neutral and impartial lawyer with excellent academic and professional credentials (i) who is or has been practicing law for at least twenty (20) years, specializing in commercial litigation and (ii) who has had experience, and is generally available to serve, as an arbitrator.

     The arbitrator shall decide the dispute or controversy in accordance with the following procedures:

	(B)		Within ten (10) days of the delivery of the Initial Submission, each party may submit to the arbitrator and the other party a reply memorandum (the “Reply Submission”), which shall not exceed 15 pages, double spaced and such other documentary evidence as the party deems necessary.
	(C)		Within ten (10) days of the expiration of the period for the delivery of the Reply Submission, the arbitrator, if he or she deems it necessary or advisable, may call a hearing which may be by telephone conference (the “Hearing”). At any Hearing, the arbitrator may ask representatives and counsel for the parties questions with respect to the issue to be decided and positions of the parties.
	(D)		Within seven (7) days after the latter to occur, if such is to occur, of (a) the Hearing or (b) the Reply Submission, the arbitrator shall render the decision and/or award.
	(E)		The arbitrator shall promptly notify the parties in writing of the decision and/or award. The award need not contain an explanation of the decision or grounds therefore.

     13.7.6 Major Disputes. (a) In the event the amount in controversy is more than $500,000, or if the amount cannot be determined, then the arbitration shall be conducted

in accordance with the Commercial Arbitration Rules of the AAA, except that (i) every person named on all lists of potential arbitrators shall be a Commercial Litigation Attorney, (ii) the arbitration shall be determined by a single arbitrator and (iii) each party shall be entitled to strike on a peremptory basis, for any reason or no reason, any or all of the names of potential arbitrators on any list submitted to the parties by the AAA and any person selected by the AAA to serve as an arbitrator by administrative appointment. In the event the parties cannot agree on a mutually acceptable arbitrator from the one or more lists submitted by the AAA within thirty (30) days after the AAA transmits to the parties its first list of potential arbitrators, the President of the Allegheny County Bar Association located in Pittsburgh, Pennsylvania shall designate three persons who, in his or her opinion, meet the criteria set forth herein, which designees may include persons named on any list submitted by the AAA. Each party shall be entitled to strike one of such three designees on a peremptory basis within ten (10) days after its receipt of such list of designees, indicating its order of preference with respect to the remaining designees. If two of such designees have been stricken by the parties, the unstricken designee shall be the arbitrator. Otherwise, the selection of the arbitrator shall be made by the AAA from the remaining designees in accordance with their mutual order of preference, or by random selection in the absence of a mutual order of preference.

     (b) Prior to any hearing on the merits, the parties shall be permitted to engage in limited discovery as permitted by the arbitrator. The parties may request to have all relevant documents produced for inspection and copying. At least ten (10) days prior to the hearing, the parties shall exchange all documents that they may introduce into evidence. The failure of a party to exchange a particular document shall automatically preclude that party from presenting that document into evidence.

     13.7.7. Costs. All dispute resolution costs, which shall include any fee for the arbitrator for services rendered, shall be borne equally by the parties. Each party shall pay its own counsel fees and expenses.

     13.7.8 Injunctive Relief. The parties hereto agree that notwithstanding and, in addition to, the rights and remedies available hereunder, the parties hereto reserve the right to seek and obtain temporary restraining orders or other emergency temporary or preliminary equitable injunctive relief from the courts of the Commonwealth of Pennsylvania situate in Allegheny County, Pennsylvania or the federal courts situated in the Western District of Pennsylvania, to preserve the status quo by enjoining or restraining a party hereto pending final and binding arbitration hereunder and the parties hereto acknowledge and agree to the right to seek such relief. The parties hereto expressly agree and acknowledge that no judicial proceeding relating to the subject matter of the arbitration shall be deemed a waiver of any party’s right to arbitrate nor shall the existence or exercise of such rights be deemed to be an adequate remedy at law in connection therewith.
