For example, if the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet is $1,300,000, then the Estimated Closing Adjustment Amount would be $200,000. The Estimated Closing Adjustment Amount, if any, will be subtracted from the cash portion of the Purchase Price payable by Buyer to Sellers pursuant to Section 1.4(b)(i).

          (b) No later than one (1) Business Day prior to the Closing Date, Sellers shall cause an estimated balance sheet of the Company as of December 31, 2006 (as adjusted to reflect the cost of the transaction and other Transaction Expenses or other transactions or adjustments in anticipation of Closing, as set forth on Schedule 1.5(b) (the “Estimated Balance Sheet”) to be prepared and delivered to Buyer, which will be accompanied by an estimated calculation of the Working Capital of the Company as of December 31, 2006, which calculation shall also reflect the items set forth on Schedule 1.5(b); however, for purposes of the Estimated Closing Adjustment Amount, any current portion of outstanding debt shall be excluded from the calculation of Working Capital.

     Section 1.6. Closing Adjustment Amount.

          (a) Subject to the provisions set forth below, the “Closing Adjustment Amount” will be an amount (which shall be a positive number) equal to the difference between (x) the Working Capital of the Company as reflected on the Closing Balance Sheet and (y) the Working Capital of the Company as reflected on the Estimated Balance Sheet.

     (i) If the Working Capital deficits of the Company as reflected on the Closing Balance Sheet and on the Estimated Balance Sheet are both less than $1,100,000, then the Closing Adjustment Amount shall automatically equal zero.

     (ii) If (A) the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet is less than the Working Capital deficit of the Company as reflected on the Closing Balance Sheet and (B) the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet is greater than or equal to $1,100,000, then the Closing Adjustment Amount will be paid to Buyer to an account specified by Buyer from and to the extent of the Working Capital Cash Escrow held by the Escrow Agent under the Cash Escrow Agreement, and to the extent the Closing Adjustment Amount is greater than the Working Capital Cash Escrow, the excess will be paid to Buyer first from the Additional Cash Escrow and secondly from the Escrow Stock.

     (iii) If (A) the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet is less than the Working Capital deficit of the Company as reflected on the Closing Balance Sheet and (B) the Working Capital deficit of the Company as reflected on the

Estimated Balance Sheet is less than $1,100,000, then the Closing Adjustment Amount shall be calculated assuming that the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet was equal to $1,100,000. Such amount will be paid to Buyer to an account specified by Buyer from and to the extent of the Working Capital Cash Escrow held by the Escrow Agent under the Cash Escrow Agreement, and to the extent the Closing Adjustment Amount is greater than the Working Capital Cash Escrow, the excess will be paid to Buyer first from the Additional Cash Escrow and secondly from the Escrow Stock.

     (iv) If (A) the Working Capital deficit of the Company as reflected on the Closing Balance Sheet is less than the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet, and (B) the Working Capital deficit of the Company as reflected on the Closing Balance Sheet is greater than or equal to $1,100,000, then the Closing Adjustment Amount will be paid by wire transfer of immediately available funds by Buyer to Sellers to the account specified by Sellers.

     (v) If (A) the Working Capital deficit of the Company as reflected on the Closing Balance Sheet is less than the Working Capital deficit of the Company as reflected on the Estimated Balance Sheet, and (B) the Working Capital deficit of the Company as reflected on the Closing Balance Sheet is less than $1,100,000, then the Closing Adjustment Amount shall be calculated assuming that the Working Capital deficit of the Company as reflected on the Closing Balance Sheet was equal to $1,100,000. Such amount will be paid by wire transfer of immediately available funds by Buyer to Sellers to the account specified by Sellers.

          (b) Within three (3) Business Days after the calculation of the Closing Adjustment Amount becomes binding and conclusive on the Parties pursuant to Sections 1.6(d) and 1.6(e), Sellers or Buyer, as the case may be, will make the payment provided for in Section 1.6(a) and/or Buyer and Sellers will deliver joint written instructions to the Escrow Agent under the Cash Escrow Agreement directing that the appropriate amount be paid to Buyer from the Working Capital Cash Escrow (and the Additional Cash Escrow and/or Escrow Stock, if applicable) with any remaining amount of the Working Capital Cash Escrow, if any, being distributed to Sellers. If the payment provided for in Section 1.6(a) is not made within 10 Business Days after such Closing Adjustment Amount becoming binding and conclusive on a Party, interest at the rate of 8% per annum shall accrue and be payable on the Closing Adjustment Amount.

          (c) Buyer shall prepare a balance sheet of the Company as of the Closing Date (the “Closing Balance Sheet”), which will include a calculation of the Working Capital of the Company as of the Closing Date. Buyer shall deliver the Closing Balance Sheet to Sellers within sixty (60) days following the Closing Date (the date of such delivery, the “Delivery Date”).

          (d) If within fifteen (15) days following the Delivery Date, Sellers have not given Buyer written notice of their objection to the Closing Balance Sheet calculation (which notice must contain (i) a statement of Sellers’ calculation of the Company’s Working Capital as of the Closing Date and (ii) the basis of Sellers’ objection), then the Working Capital amount reflected in the Closing Balance Sheet will be binding and conclusive on the Parties and will be used in computing the Closing Adjustment Amount.

          (e) If Sellers duly give Buyer such notice of objection within fifteen (15) days following the Delivery Date, and if Sellers and Buyer fail to resolve the issues outstanding with respect to the Closing Balance Sheet and the calculation of the Working Capital reflected in the Closing Balance Sheet within fifteen (15) days of Buyer’s receipt of the objection notice from Sellers, Sellers and Buyer shall submit the issues remaining in dispute to Lattimore Black Morgan & Cain, PC (the “Independent

Accountants”) for resolution. If issues are submitted to the Independent Accountants for resolution, (i) Sellers and Buyer shall furnish or cause to be furnished to the Independent Accountants such work papers and other documents and information relating to the disputed issues as the Independent Accountants may request and are available to that Party or its agents and shall be afforded the opportunity to present to the Independent Accountants any material relating to the disputed issues and to discuss the issues with the Independent Accountants; (ii) the determination by the Independent Accountants, as set forth in a notice to be delivered to Sellers and Buyer within thirty (30) days of the submission to the Independent Accountants of the issues remaining in dispute, will be final, binding and conclusive on Sellers and Buyer; and (iii) Sellers and Buyer shall pay equal percentages of the fees and costs of the Independent Accountants in connection with such determination, unless one Party’s calculation of the Working Capital of the Company as of the Closing Date differs from the calculation of the Working Capital of the Company as of the Closing Date by the Independent Accountants by more than 33.33% in which case such Party shall then pay one-hundred percent (100%) of the Independent Accountant’s fees and costs in connection with such determination. In the event that both Parties’ calculation of the Closing Adjustment Amount differs from the determination of the Independent Accountant by more than 33.33%, then the Party whose calculation differs from the determination of the Independent Accountants by the greatest amount shall pay one-hundred percent (100%) of the Independent Accountant’s fees and costs.

          (b) If the Closing occurs, Buyer will have no indemnification liability under this Article VIII with respect to (i) any claim made under Section 8.3(a) or (ii) any claims made under Section 8.3(b) relating to any covenant or obligation to be performed and complied with by Buyer on or prior to the Closing Date, unless on or before the date that is eighteen (18) months following the Closing Date, Sellers notify Buyer of a claim specifying the factual basis of that claim in reasonable detail to the extent then known by Sellers; provided, however, that any claim for indemnification or reimbursement made under Section 8.3(b) not based upon any covenant or obligation to be performed and complied with prior to the Closing Date may be made at any time.

     Section 8.7. Procedure for Indemnification — Third Party Claims.

          (a) Promptly after receipt by an indemnified party under Section 8.2 or Section 8.3, as the case may be (an “Indemnified Person”), of notice of the assertion of any third-party claim against it, such Indemnified Person shall give notice to the Person obligated to indemnify such Person under Section 8.2 or Section 8.3, as the case may be (an “Indemnifying Person”), of the assertion of such third-party claim, provided that the failure to notify the Indemnifying Person will not relieve the Indemnifying Person of any liability that it may have to any Indemnified Person, except to the extent that the Indemnifying Person demonstrates that the defense of such third-party claim is prejudiced by the Indemnified Person’s failure to give such notice.

          (b) If an Indemnified Person gives notice to the Indemnifying Person pursuant to Section 8.7(a) of the assertion of a third-party claim, the Indemnifying Person will be entitled to participate in the defense of such third-party claim and, to the extent that the Indemnifying Person wishes (unless (i) the Indemnifying Person is also a Person against whom the third-party claim is made and the Indemnified Person determines in good faith that joint representation would be inappropriate, or (ii) the Indemnifying Person fails to provide reasonable assurance to the Indemnified Person of its financial capacity to defend such third-party claim and provide indemnification with respect to such third-party claim), by providing written notice thereof to the Indemnified Person within ten (10) days of the delivery of such notice pursuant to Section 8.7(a), to assume the defense of such third-party claim with counsel satisfactory to the Indemnified Person. After notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense of such third-party claim, the Indemnifying Person will not, so long as it diligently conducts such defense, be liable to the Indemnified Person under this Article VIII for any fees of other counsel or any other expenses of any Indemnified Person with respect to the defense of such third-party claim, in each case subsequently incurred by the Indemnified Person in connection with the defense of such third-party claim, other than reasonable costs of investigation. If the Indemnifying Person assumes the defense of a third-party claim, (x) such assumption will conclusively establish for purposes of this Agreement that the claims made in that third-party claim are within the scope of and subject to indemnification, and (y) no compromise or settlement of such third-party claims may be effected by the Indemnifying Person without the Indemnified Person’s consent unless (A) there is no finding or admission of any violation of any Legal Requirement or any violation of the rights of any Person by any Indemnified Person; and (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Person, and the Indemnified Person will have no liability with respect to any compromise or settlement of such third-party claims effected without its consent. If notice is given to an Indemnifying Person of the assertion of any third-party claim and the Indemnifying Person does not, within ten (10) days after the Indemnified Person’s notice is given, give notice to the Indemnified Person of its election to assume the defense of such third-party claim, the Indemnifying Person will be bound by

any determination made in such third-party claim or any compromise or settlement effected by the Indemnified Person.

          (c) Notwithstanding the foregoing, if an Indemnified Person determines in good faith that there is a reasonable probability that a third-party claim may adversely affect such Indemnified Person other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnified Person may, by notice to the Indemnifying Person, assume the exclusive right to defend, compromise or settle such third-party claim, but the Indemnifying Person will not be bound by any determination of any third-party claim so defended for the purposes of this Agreement or any compromise or settlement effected without its consent (which may not be unreasonably withheld).

          (d) With respect to any third-party claim subject to indemnification under this Article VIII: (i) both the Indemnified Person and the Indemnifying Person, as the case may be, shall keep the other Person fully informed of the status of such third-party claim and any related Proceedings at all stages thereof where such Person is not represented by its own counsel, and (ii) the Indemnified Persons and Indemnifying Persons shall render to each other such assistance as they may reasonably require of each other and cooperate in good faith with each other in order to ensure the proper and adequate defense of any third-party claim.

          (e) With respect to any third-party claim subject to indemnification under this Article VIII, the Parties shall cooperate in such a manner as to preserve in full (to the extent possible) the confidentiality of all confidential information and the attorney-client and work-product privileges. In connection therewith, each party agrees that: (i) it will use its reasonable best efforts, in respect of any third-party claim in which it has assumed or has participated in the defense, to avoid production of confidential information (consistent with applicable law and rules of procedure), and (ii) all communications between any Parties hereto and counsel responsible for or participating in the defense of any third-party claim will, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.

     Section 8.8. Procedure For Indemnification — Other Claims. A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the party from whom indemnification is sought and will be paid promptly after such notice.

     Section 8.9. Materiality Qualifications. For purposes of calculating the amount of Damages to which the Buyer Indemnified Persons and Seller Indemnified Persons are entitled under this Article VIII (but not for purposes of determining whether a representation or warranty has been breached), the terms “material,” “materiality,” and “Material Adverse Effect” will be disregarded.

     Section 8.10. Other Actions. Notwithstanding anything to the contrary in this Article VIII, any liabilities arising from criminal activity, willful misstatements, willful omission, willful breaches, willful nonfulfillments and willful violations or for fraud shall survive the periods set forth in Section 8.6 and shall not be subject to the limitations on liability set forth in Sections 8.4 and 8.5.

     Section 8.11. Exclusive Remedy. Each of the Parties agrees that its sole recourse for any breach or default hereunder, or for any other matter as to which indemnification is provided to it in this Article VIII, shall be limited to (a) the indemnification provisions set forth herein, (b) any equitable relief to which it is entitled, and (c) any action based on the fraud or willful misconduct of any Party.

     Section 9.6. Severability.
