On the terms and subject to the conditions set forth in this Agreement, in consideration of the transfer of the Membership Interests in the Company by Seller to Purchaser, Purchaser shall pay to Seller at Closing $2,000,000 in cash (the “Closing Date Cash Payment”).

Both the latter payment and the Closing Date Cash Payment shall be paid by wire transfer of immediately available funds to such account as shall have been designated by Seller prior to the date of the relevant payment.

2.3 Annual Earn-Out Payments. (a) As additional consideration for the sale of the Membership Interests by Seller to Purchaser, for the three-year period following the first day of the calendar month immediately following the Closing (referred to herein as the “Earn-Out Period”), Purchaser shall pay to Seller with respect to each Calculation Period within the Earn-Out Period an amount (each an “Earn-Out Payment”) equal to (A) the EBITA generated by the Business for the applicable Calculation Period multiplied by (B) the percentage specified on Schedule 2.3.

(b) For purposes hereof, the following definitions shall apply:

(i) “Calculation Periods” with respect to the Earn-Out Payments means (i) the period beginning on the first day of the calendar month following the Closing Date and ending on December 31, 2006, (ii) the twelve-month period beginning on January 1, 2007 and ending on December 31, 2007, (iii) the twelve-month period beginning January 1, 2008 and ending on December 31, 2008 and (iv) the period beginning on January 1, 2009 and ending in 2009 on the last day of the month in which the Closing Date occurs.

(ii) “EBITA” for any Calculation Period means the net income of the Business for the applicable Calculation Period, before the subtraction of any interest, income taxes or goodwill amortization, but after deduction for depreciation of the Business. All calculations of EBITA shall be made in accordance with GAAP as in effect on the Closing Date, as applied by Purchaser consistent with past practices, provided (i) that any payments, charges or expenses for allocation of home office, executive, general and administrative expenses or other payments, charges, expenses or commissions of or paid by Purchaser and/or its affiliates

(including any affiliate that itself succeeds to the Business) shall not be deducted for purposes of the calculation, except that any services (other than referrals) rendered to the Business by Purchaser and/or its affiliates (including other practice groups) that are provided directly to the Business shall be charged to the Business for purposes of the calculation at customary inter-group rates and (ii) no expenses incurred pursuant to Section 2.5 (relating to the Earn-Out Calculation Statements) shall be deducted for purposes of the calculation. Further, for avoidance of doubt, no Earn-Out Payment or Cumulative Earn-Out Payment shall be deducted for purposes of such calculation for any year, whether in the year such payment accrues, is paid, or in any other year.

2.4 Cumulative Earn-Out Payment. (a) Subject to clause (iv) of this Section 2.4, as additional consideration for the sale of the Membership Interests by Seller to Purchaser, Purchaser shall pay to Seller an amount (the “Cumulative Earn-Out Payment”) determined as follows if the Business Revenue generated over the three year period (the “Cumulative Earn-Out Period”) beginning on January 1, 2007 and ending on December 31, 2009 exceeds $100 million:

(i) If the Business Revenue over the Cumulative Earn-Out Period is equal to or greater than $100 million, but less than $125 million, then the Cumulative Earn-Out Payment to be paid to Seller shall be (A) $2 million plus (B) an amount (the “Prorated Earn-Out Amount”) as determined in accordance with the following formula:

Prorated Earn-Out Amount =

[	(Business Revenue - $100 million)	]	x	$3 million
	$25 million

(ii) Subject to clause (iv) of this Section 2.4, if the Business Revenue over the Cumulative Earn-Out Period is equal to or greater than $125 million, then the Cumulative Earn-Out Payment to be paid to Seller shall be $5 million.

(iii) If the Business Revenue over the Cumulative Earn-Out Period is less than $100,000,000, Purchaser shall not be required to make any Cumulative Earn-Out Payment.

(iv) Notwithstanding anything to the contrary in this Section 2.4, Purchaser will not be required to make a Cumulative Earn-Out Payment to Seller if the Cumulative EBITA Margin of the Company is less than twenty percent (20%) over the Cumulative Earn-Out Period.

(b) For purposes hereof, the following definitions shall apply:

(i) “Cumulative EBITA Margin” means the percentage obtained by dividing the aggregate EBITA over the Cumulative Earn-Out Period by the aggregate Business Revenue over the Cumulative Earn-Out Period.

(ii) “Business Revenue” means with respect to a period, the revenue of the Business for the applicable period, as determined on an accrual basis in accordance with GAAP, consistently applied. For purposes of this definition, Business Revenue shall exclude the

reimbursement of out-of-pocket expenses incurred by the Business for incidental services (e.g.; travel, copying and courier charges, etc.) that are not integral to the services provided by the Business.

2.5 Earn-Out Statements. (a) Within sixty (60) days of the end of each Calculation Period within the Earn-Out Period, Purchaser shall prepare a statement setting forth Purchaser’s calculation of the amount of the Earn-Out Payment that is due with respect to the relevant period, and within sixty (60) days of the end of the Cumulative Earn-Out Period, Purchaser shall prepare a statement setting forth Purchaser’s calculation of the amount of the Cumulative Earn-Out Payment said statements being referred to herein as the “Earn-Out Calculation Statements”). Concurrently with the delivery of each Earn-Out Calculation Statement, Purchaser shall pay Seller the amount of the Earn-Out Payment or Cumulative Earn-Out Payment, as applicable, reflected thereon by wire transfer of immediately available funds to such account as shall be designated from time to time by Seller. Purchaser shall provide Seller, in addition to said statements, such additional documentation and supporting information as may be necessary to allow Seller to review and verify Purchaser’s determinations and calculations as reflected in each such Earn-Out Calculation Statement.

(b) Seller shall notify Purchaser of any disagreement that Seller may have with Purchaser’s calculation of the Earn-Out Payments or Cumulative Earn-Out Payment, as applicable, within thirty (30) days of the receipt thereof by Seller. If Seller advises Purchaser of its disagreement with an Earn-Out Calculation Statement, Seller and Purchaser shall attempt in good faith to resolve any dispute within thirty (30) days of receipt by Purchaser of Seller’s objection and Purchaser shall make any adjusting payment and resolve the disputed Earn-Out Calculation Statement within three Business Days of the dissolution of the dispute. If within said thirty (30) day period, Seller and Purchaser are unable to resolve the dispute, either Purchaser or Seller shall be entitled to submit the dispute for resolution to a nationally recognized accounting firm reasonably acceptable to Seller and Purchaser (the “Independent Accountant”) or in the absence of an agreement, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP. If the Independent Accountant is retained, each of Purchaser and Seller shall submit a written statement summarizing its position on the disputed payments to the Independent Accountant not more than ten (10) Business Days after its appointment, together with any necessary supporting documentation as it deems necessary or as requested by the Independent Accountant. The Independent Accountant shall be instructed to render its decision on the disputed amounts within thirty (30) days of receipt of the written statements. The decision of the Independent Accountant shall be final and binding on, and shall not be subject to appeal by Seller or Purchaser. The Earn-Out Calculation Statement shall be revised to reflect the determination of the Independent Accountant and any payments required to be made as a result thereof shall be paid within three (3) Business Days of the final determination by the Independent Accountant. The fees of the Independent Accountant shall be borne equally by Purchaser and Seller.

(c) During the Earn-Out Period and Cumulative Earn-Out Period, appropriate measures will be taken by Purchaser to ensure that the Company continues to generate separate financial statements for the Business at least for each calendar quarter sufficient to allow the Earn-Out Payments and Cumulative Earn-Out Payments to be reviewed and calculated in accordance with this Agreement setting forth, without limitation, EBITA for the Calculation

Period in which such quarter is included and EBITA and Business Revenue for the Cumulative Earn-Out Period to date.

2.6 Purchase Price Allocation. The parties agree to allocate the combined amount consisting of the Closing Date Cash Payment plus the tax purchase price under the Nextra Asset Purchase Agreement among the assets and non-competition provisions contained in Section 11.3 in accordance with Section 1060 of the Code and the regulations thereunder and the principles set forth in Section 3.3 of the Nextra Asset Purchase Agreement provided however, that the parties agree to allocate any consideration in excess of the Closing Date Cash Payment (less any amount allocated to the non-competition undertaking) provided in the Nextra Asset Purchase Agreement in its entirety to "Class VII assets" (in goodwill and going concern value) pursuant to Treasury Regulations §§ 1.1060-1(c)(2). Any adjustment to the Closing Date Cash Payment shall be allocated as provided by the Treasury Regulation § 1.1060-1(c).

Prior to destroying any records related to Seller for the period prior to the Closing Date, Purchaser shall notify Seller thirty (30) days in advance of any such proposed destruction of its intent to destroy such records, and Purchaser will permit Seller to retain any such records; provided, however, that failure to provide such notification shall not constitute a basis for any liability or claim for damages.

11.3 Non-Competition Undertaking. (a) From and after the Closing Date until the fourth anniversary thereof (the “Restricted Period”), the Seller shall not, directly or indirectly:

ARTICLE XII

SURVIVAL AND INDEMNIFICATION

12.1 Survival of Representations. The representations and warranties of the Company, Seller and Purchaser contained in this Agreement shall survive the Closing Date but shall terminate twelve (12) months after the Closing Date; provided, however, that the representations and warranties regarding Tax Matters set forth in Section 3.7 shall survive for the applicable statute of limitation period and the Title and Authorization Warranties shall survive indefinitely. No claim may be made with respect to any alleged breach of a representation or warranty of Seller or Purchaser contained in this Agreement, whether for indemnification in respect thereof or otherwise, unless written notice of such claim setting forth the alleged breach and resulting claimed damages in reasonable detail is given to Seller or Purchaser, as applicable, within the

period specified in the immediately preceding sentence, in which case, the survival period with respect to such claim shall be extended until it is resolved.

12.2 Seller Indemnifications. Seller shall indemnify Purchaser and its Representatives and Affiliates, and hold each of them harmless from and against any and all Losses incurred by any of them in connection with, arising out of, or resulting from any of the following:

(a) any breach or inaccuracy of any representation or warranty made by Seller in this Agreement or any Related Agreement; or

(b) any failure by the Company or Seller to perform any agreement, covenant or obligation of the Company or Seller pursuant to this Agreement or any Related Agreement, provided that the foregoing shall only apply to covenants of the Company which are required to be performed prior to the Closing.

12.3 By Purchaser. Purchaser shall indemnify Seller and its Representatives and Affiliates, and hold each of them harmless from and against any and all Losses incurred by any of them in connection with, arising out of or resulting from any of the following:

(a) any breach or inaccuracy of any representation or warranty made by Purchaser in this Agreement or any Related Agreement; or

(b) any failure by Purchaser to perform any agreement, covenant or obligation of Purchaser pursuant to this Agreement or any Related Agreement; or

(c) any Liability incurred by Seller under or in connection with a guarantee or other assurance of performance provided by Seller to Nextra or ▇▇▇▇▇▇ ▇▇▇▇▇ in connection with any Real Property Lease.

12.4 Notice of Claims. If a claim (a “Claim”) is proposed to be made by a party entitled to indemnification hereunder (the “Indemnified Party”) against the party from which indemnification is claimed (the “Indemnifying Party”), the Indemnified Party shall give written notice (a “Claim Notice”) to the Indemnifying Party as soon as practicable after the Indemnified Party becomes aware of any fact, condition or event which may give rise to a Loss for which indemnification may be sought under this Article XII. If any legal proceeding is commenced against any party entitled to the benefit of indemnity hereunder, written notice thereof shall be given to the Indemnifying Party as promptly as practicable (and in any event within ten (10) Business Days after the service of the citation or summons). The failure of any Indemnified Party to give timely notice hereunder shall not affect rights to indemnification hereunder, except to the extent that the Indemnifying Party demonstrates actual prejudice caused by such failure. Notwithstanding the foregoing, a Claim Notice that relates to a representation or warranty that is subject to the survival period set forth in Section 12.1 must be made within such survival period, whether or not the Indemnifying Party is prejudiced by any failure to give a Claim Notice relating thereto. A Claim Notice shall describe in reasonable detail the nature of the Claim, including an estimate of the amount of Losses that have been or may be suffered or incurred by the Indemnified Party attributable to such Claim, the basis of the Indemnified Party’s request for indemnification under this Agreement and all information in the Indemnified Party’s possession relating to such Claim.

12.5 Assumption of Defense of Third Party Claims. After receipt of a Claim Notice with respect to a claim, demand or action initiated by a Person which is not a party to this Agreement (a “Third Party Claim”), the Indemnifying Party shall be entitled, if it so elects, at its own cost, risk and expense, to (i) take control of the defense and investigation of such Third Party Claim and (ii) employ and engage attorneys of its own choice to handle and defend the same. If the Indemnifying Party fails to assume the defense of such Third Party Claim within ten (10) Business Days after receipt of the Claim Notice, the Indemnified Party against which such Third Party Claim has been asserted will (upon delivering notice to such effect to the Indemnifying Party) have the right to undertake, at the Indemnifying Party’s cost and expense, the defense, compromise or settlement of such Third Party Claim on behalf of and for the account and risk of the Indemnifying Party; provided, however, that such Third Party Claim shall not be compromised or settled without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. The party that assumes the defense of the Claim shall keep the other party reasonably informed of the progress of any such defense, compromise or settlement and, provided, further, that in any event, the Indemnified Party may participate in such defense at its own expense.

12.6 Settlement of Third Party Claims. In the event that the Indemnified Party settles any Third Party Claim without the prior written consent of the Indemnifying Party, the Indemnifying Party shall have no further indemnification obligations under this Article XII with respect to such Third Party Claim; provided, however, that if the Indemnifying Party refuses to defend or otherwise handle such Third Party Claim and it is subsequently determined that the Indemnifying Party is or was obligated to defend or indemnify the Indemnified Party with respect to such Third Party Claim, then the Indemnifying Party shall remain obligated with respect to such settlement amount. If the Indemnifying Party controls the defense of any such Third Party Claim, the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld or delayed) before entering into any settlement of a Third Party Claim or ceasing to defend such Third Party Claim if, pursuant to or as a result of such settlement or cessation, injunctive or other equitable relief shall be imposed against the Indemnified Party or if such settlement or cessation does not expressly and unconditionally release the Indemnified Party from all liabilities and obligations with respect to such Third Party Claim, without prejudice. In the event that the Indemnifying Party proposes a settlement to any Third Party Claim with respect to which the Indemnifying Party is or was entitled to defend, which settlement is satisfactory to the party instituting such Third Party Claim, and the Indemnified Party withholds its consent to such settlement, and thereafter a final judgment is entered against the Indemnifying Party or Indemnified Party pursuant to which Losses exceed the amount of the proposed settlement, then in such case the Indemnifying Party shall have no obligation to indemnify the Indemnified Party under this Article XII against and in respect of the amount by which the Losses resulting from such final judgment exceed the amount of the proposed settlement.

12.7 Limitations on Indemnity Payments.

(a) Threshold. Seller shall not be liable to Purchaser under Section 12.2(a) for any Losses, unless and until (i) each individual amount otherwise due Purchaser exceeds $5,000 (excluding legal fees and expenses), and (ii) the aggregate amount of all such Losses under this Agreement, otherwise due Purchaser (excluding Losses incurred in any individual claim of less

than $5,000) exceeds an accumulated total of $100,000, and thereafter the total amount of all such Losses in excess of $5,000 per claim (excluding legal fees and expenses) actually incurred (excluding the first $100,000) shall be indemnifiable as and to the extent herein provided.

(b) Maximum Indemnity. Seller’s aggregate liability under Sections 12.2(a) for all claims for Losses incurred by Purchaser (and its Representatives and Affiliates) shall not in any event exceed the Closing Date Cash Payment.

(c) Tax Gross-Up. The amount of any loss recoverable by a party entitled to indemnification shall be reduced by the amount of any tax benefit actually realized by the Indemnified Party with respect to the Claim.

12.8 Characterization of Indemnity Payments. Any indemnity payments made pursuant to this Article XII shall be treated as an adjustment to the aggregate purchase price to the maximum extent possible.

12.9 Offset Rights. Purchaser shall have the right to withhold payments under this Agreement or offset payments otherwise required to be made to Seller hereunder against any payments to which Purchaser is entitled under this Article XII. Notwithstanding the foregoing, Purchaser agrees to exercise its right of offset or withholding only in a commercially reasonable manner and only after providing Seller not less than ten (10) Business Days' advance written notice. In addition, Purchaser agrees to exercise its right of offset or withholding only up to an amount equal to the reasonably ascertainable or estimable amount of the Loss incurred or which reasonably may be incurred by Purchaser with respect to the events or circumstances giving rise to Purchaser's exercise of such rights.

12.10 Mitigation; Exclusive Remedy. (a) Any Indemnified Party having a claim under this Article XII shall make a good faith effort to recover all Losses from insurers of such Indemnified Party under applicable insurance policies so as to reduce the amount of any Losses hereunder. The amount of any Loss shall be reduced by the amounts actually and irrevocably recovered by the Indemnified Party with respect to any claim.

(b) The rights and remedies of Seller and Purchaser under this Article XII are exclusive and in lieu of any and all other rights and remedies which Seller or Purchaser may have under or in connection with this Agreement for monetary relief (but not injunctive relief) with respect to any breach or failure to perform any covenant or agreement or breach or inaccuracy of any representation or warranty set forth in this Agreement. The foregoing limitation shall not apply with respect to claims for intentional misrepresentation, intentional breach, willful misconduct or fraud.

(c) Prior to recovering any loss against Seller (but without limiting Purchaser's right to exercise its offset or withholding rights in accordance with Section 12.9), Purchaser agrees to use good faith commercial efforts to pursue and prosecute a claim for indemnification against Nextra or ▇▇▇▇▇▇ ▇▇▇▇▇ to the extent that the Claim asserted by Purchaser against Seller gives rise to a corresponding claim for indemnification against either or both of such Persons under the Nextra Asset Purchase Agreement; provided, that Purchaser shall not be required to continue to pursue a claim for indemnification against Nextra or ▇▇▇▇▇▇ ▇▇▇▇▇

if, in the opinion of counsel to Purchaser, recovery from such Persons is unlikely or cost prohibitive (and provided that Seller agrees in writing to waive any statute of limitation applicable to the Claim) and; provided, further, that Purchaser shall not be required to pursue an appeal of any adverse judgment.

13.8 Severability. If any provision of this Agreement shall be held invalid, illegal or unenforceable, the validity, legality or enforceability of the other provisions hereof shall not be affected thereby, and there shall be deemed substituted for the provision at issue a valid, legal and enforceable provision as similar as possible to the provision at issue.

13.16 Representation of Counsel; Mutual Negotiation. Each party has had the opportunity to be represented by counsel of its choice in negotiating this Agreement. This Agreement shall therefore be deemed to have been negotiated and prepared at the joint request, direction, and construction of the parties, at arm’s-length, with the advice and participation of counsel, and will be interpreted in accordance with its terms without favor to any party.
