STOCK PURCHASE AGREEMENT

                    THIS AGREEMENT is made on July 19, 2006, by and between DIAMONDCLUSTER INTERNATIONAL B.V., a company incorporated with limited liability under the laws of the Netherlands (the “Seller”); and MERCER MANAGEMENT CONSULTING, INC., a Delaware corporation (“Buyer”). Unless otherwise provided, capitalized terms used herein are defined in Article XI below.

                    WHEREAS, DiamondCluster International, Inc., a Delaware corporation (“Parent”) owns all of the issued and outstanding shares of common stock of the Seller; and

                    WHEREAS, Seller owns, directly or indirectly, all of the issued and outstanding equity interests in the entities listed on Annex 1 attached hereto (such equity interests collectively being referred to herein as the “Shares”) (each such entity listed on Annex 1 shall be referred to herein as a “Company” and collectively, the “Companies”); and

                    WHEREAS, Seller desires to sell, and Buyer desires to purchase, the Shares on the terms and subject to the conditions set forth in this Agreement.

                    NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE I
PURCHASE AND SALE OF SHARES

                    1.01 Purchase and Sale of Shares. At the Closing, upon the terms and subject to the conditions set forth in this Agreement, Seller shall sell, assign, transfer, and convey to Buyer, and Buyer shall purchase and acquire from Seller, all of the Shares against payment at the Closing pursuant to this Article I.

                    1.02 Purchase Price.

(a) The Purchase Price to be paid by Buyer for the Shares pursuant to this Agreement and the rights granted pursuant to the UK Comfort Letter shall be, collectively, Twenty Million U.S. Dollars ($20,000,000), subject to adjustment as provided in Section 1.02(b) (the “Purchase Price”). The Purchase Price is payable in the manner provided in Section 1.03.

(b) (i) Schedule 1.02(b)(i) sets forth a preliminary estimate of the Working Capital Amount (the “Preliminary Working Capital Amount”). The cash due at Closing pursuant to clause (A) of Section 1.03(b)(ii) will be increased or decreased in accordance with this Section 1.02(b)(i) to the extent that the Preliminary Working Capital Amount does not equal Four Million Five Hundred Thousand U.S. Dollars ($4,500,000), subject to adjustment based upon the Revised Schedule (defined below) as provided in clauses (ii) and (iii) below. To the extent that the Preliminary Working Capital Amount is less than Four Million Five Hundred Thousand U.S. Dollars ($4,500,000), the cash due to Seller at Closing pursuant to clause (A) of Section 1.03(b)(ii) shall be decreased by the amount by which the Preliminary Working Capital Amount is less than Four Million Five Hundred Thousand U.S. Dollars ($4,500,000). To the extent that the Preliminary Working Capital Amount exceeds Four Million Five Hundred Thousand U.S. Dollars ($4,500,000), the cash due to Seller at Closing pursuant to clause (A) of Section 1.03(b)(ii) shall be increased by the amount of such excess.

(ii) Within 90 days following the Closing Date, Seller and Buyer shall jointly develop a revised Schedule 1.02(b)(i), with respect to the actual Working Capital Amount as of the Effective Time (the “Revised Schedule”). The Revised Schedule shall be prepared in accordance with U.S. GAAP (except as otherwise provided in the definition of Working Capital Assets), applied on a consistent basis in accordance with past practices of Seller and consistent with the calculation of the Preliminary Working Capital Amount, in order to reflect the actual Working Capital Amount as of the Closing Date. Each party shall reasonably cooperate with the other and its representatives in connection with the preparation of the Revised Schedule. In the preparation of the Revised Schedule, each party shall review the work papers used in the preparation thereof and such other documents as a party may reasonably request in connection with its review of the Revised Schedule.

(iii) In the event Buyer and Seller do not agree on the final Revised Schedule within 90 days following the Closing Date, Buyer and Seller will use reasonable efforts to resolve any such disputes, but if a final resolution is not obtained within 10 days, any remaining disputes shall be submitted within 5 days following the end of such 10 day period to a national accounting firm in the following order: Ernst & Young, Price WaterhouseCoopers, or other national accounting firm that does not have a material conflict selected by mutual agreement of Buyer and Seller (the “Reviewing Accountant”), who will resolve any such disputes within 30 days after such submission. The determination of the Reviewing Accountant will be conclusive and binding upon the parties in the manner and to the same effect as a binding arbitration award. Each party will bear one-half of the fees and expenses of the Reviewing Accountant.

(iv) If the Working Capital Amount exceeds the Preliminary Working Capital Amount, then Buyer shall pay to Seller within 10 Business Days following final determination of the Working Capital Amount an amount equal to the excess. If the Working Capital Amount is less than the Preliminary Working Capital Amount, then Seller shall pay to Buyer within 10 Business Days following final determination of the Working Capital Amount an amount equal to the deficit. Any payments to Buyer required under this clause (iv) shall be made first by disbursing the WCA Escrow Amount by Buyer and Seller giving written notice to the escrow agent in accordance with the Escrow Agreement with wire transfer instructions provided by the party to whom the payment is to be made. Any further payments to Buyer or any payments to Seller required under this clause (iv) shall be made by wire transfer of same day funds in accordance with written wire transfer instructions provided by the party to whom the payment is to be made.

(v) (A) In addition to the Working Capital Amount adjustment, if any, described above, Buyer shall also pay Seller an additional amount as an adjustment to the Purchase Price (the “Contingent Payment”), subject to the attainment of certain Single Count Revenue targets, as follows:

(1) If the Cluster Single Count Revenue is less than or equal to $70 million, then no Contingent Payment is due.

(2) If the Cluster Single Count Revenue is greater than $70 million but less than or equal to $77.5 million, then the Contingent Payment will be equal to the

amount by which the Cluster Single Count Revenue exceeds $70 million, provided that in no event shall the Contingent Payment payable pursuant to this clause (v)(A)(2) exceed $5 million.

(3) If the Cluster Single Count Revenue is greater than $77.5 million, then the Contingent Payment will be (i) $5 million plus (ii) 20% of the amount by which the Cluster Single Count Revenue exceeds $77.5 million, provided that in no event shall the total Contingent Payment payable pursuant to this clause (v)(A)(3) exceed $7 million.

(B) For purposes hereof, “Cluster Single Count Revenue” shall mean the aggregate Single Count Revenue of the Companies (and the ▇▇▇▇▇▇ MC Affiliates) during the 18 months immediately following the Effective Date that are attributable to the Employees. “Single Count Revenue” of the Companies (and the ▇▇▇▇▇▇ MC Affiliates) shall be the aggregate gross fee amounts billed by the Companies (and such ▇▇▇▇▇▇ MC Affiliates), less out of pocket pass-through expenses and bad-debt write-offs consistent with past practice. For purposes of the calculation of Cluster Single Count Revenue, Buyer shall allocate Single Count Revenue to the Employees in a manner that is consistent with its prior practices (since 2003) and that does not discriminate against the Employees. The calculation of the Contingent Payment, if any, shall be made in a manner consistent with the methodology and examples described in Exhibit C.

(C) Buyer and Seller will endeavor to calculate the Contingent Payment no later than 45 days after the 18-month anniversary of the Effective Date. In the event Buyer and Seller do not agree on such calculation during such 45-day period, Buyer and Seller will use reasonable efforts to resolve any such disputes, but if a final resolution is not obtained within 10 days, any remaining disputes shall be submitted within 5 days following the end of such 10 day period to the Reviewing Accountant, who will resolve any such disputes within 30 days after such submission. The determination of the Reviewing Accountant will be conclusive and binding upon the parties in the manner and to the same effect as a binding arbitration award. Each party will bear one-half of the fees and expenses of the Reviewing Accountant.

(D) The Contingent Payment, if any, required under this Section 1.02(b)(v) shall be made by wire transfer of same day funds, in accordance with written wire transfer instructions provided by Seller to Buyer, no later than the 59th day after the 18-month anniversary of the Effective Date (or, if later, 10 Business Days after the final determination of the Contingent Payment pursuant to Section 1.02(b)(v)(C) above).

(c) The parties have agreed to allocate the Purchase Price as provided on Schedule 1.02(c). The Seller and the Buyer shall (i) be bound by such allocation for purposes of determining any Taxes, (ii) prepare and file all Tax Returns to be filed with any taxing authority in a manner consistent with such allocation; and (iii) take no position inconsistent with such allocation in any Tax Return, any proceeding before any taxing authority, or otherwise. In the event such allocation is disputed by any taxing authority, the party receiving notice of such dispute shall promptly notify the other party of such dispute, and the Seller and the Buyer shall cooperate in good faith in responding to such challenge in order to preserve the effectiveness of such allocation.

          1.03 The Closing.

          (a) The closing of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of Buyer in New York, New York, at 10:00 A.M. on the third Business Day following full satisfaction or due waiver of all of the closing conditions set forth in Article II hereof (other than those to be satisfied at the Closing) or on such other date as is mutually agreeable to Buyer and Seller. The date of the Closing is herein referred to as the “Closing Date.” Unless otherwise mutually agreed by the parties in writing, the Closing shall be effective for economic purposes hereunder as of the close of business (such time, the “Effective Time”) on July 31, 2006 (such date, the “Effective Date”).

          (b) Subject to the terms and conditions set forth in this Agreement, the parties hereto shall consummate the following transactions on the Closing Date:

          (i) Seller shall deliver to Buyer stock certificates (or their substitute for non-stock entities), if any, representing the Shares duly endorsed for transfer or accompanied by duly executed stock powers;

          (ii) Buyer shall deliver: (A) to Seller the amount of the Purchase Price less the WCA Escrow Amount by wire transfer of immediately available funds to one or more accounts designated by Seller to Buyer in writing no later than two Business Days prior to the Closing and (B) to the escrow agent the WCA Escrow Amount by wire transfer of immediately available funds to an account designated by the escrow agent pursuant to Section 1.04;

          (iii) Buyer and Seller shall make such other deliveries as are required by and in accordance with Article II hereof.

          1.04 Escrow.

          (a) On the Closing Date, Seller, as collateral security for Damages of Buyer that are subject to indemnification under Article VIII, shall execute and deliver an Escrow Agreement substantially in the form attached hereto as Exhibit A (the “Escrow Agreement”) and Seller shall deposit with the escrow agent an unconditional letter of credit from a nationally recognized financial institution in an amount equal to Two Million U.S. Dollars ($2,000,000) (the “Escrow Amount”). The Escrow Agreement shall provide for escrow of the Escrow Amount for a period of three years (and such longer period as may be necessary to resolve any claims made prior to the end of such period) with disbursement of the remaining balance of the Escrow Amount promptly thereafter. After such period, Buyer will continue to have unsecured indemnification rights in accordance with Article VIII.

          (b) In addition, as collateral security for final payment under Section 1.02(b)(iv) after completion of the Revised Schedule, Buyer shall deposit with the escrow agent an amount equal to Eight Hundred Thousand U.S. Dollars ($800,000) (the “WCA Escrow Amount”). The Escrow Agreement shall provide for escrow of the WCA Escrow Amount for a period of 90 days (and such longer period as may be necessary to resolve any claims under the provisions of this Agreement made prior to the end of such period) with disbursement of the remaining balance of the WCA Escrow Amount promptly thereafter.

          1.05 Pre-Closing and Simultaneous Transactions.

          (a) At the Closing, in addition to the purchase of the Shares, Seller shall, for the consideration set forth in Section 1.02, deliver a letter to Buyer regarding the employees who are listed on Schedule 1.05(a) (the “UK Employees”) substantially in the form of Exhibit B attached hereto (the “UK Comfort Letter”). Buyer will, or will cause one of its Affiliates to, offer employment, as of the Closing, to the UK Employees.

          (b) In addition, the “Cluster” and “Cluster Consulting” registered service marks or applications thereof (which are listed on the Intellectual Property Schedule) (collectively, the “Trademarks”) shall be transferred from DiamondCluster International IC LLC to DiamondCluster International S.L. Sociedad Unipersonal prior to Closing by executing a Service ▇▇▇▇ Purchase Agreement in the form of Exhibit D attached hereto (the “Trademark Assignment”).

          (c) The parties acknowledge that certain other individuals as listed on Schedule 1.05(c) are not employees of the Companies, although they are currently working for DiamondCluster International FZ LLC in Dubai, UAE on a temporary basis, and will not become employees of Buyer upon the Closing (“Transition Employees”). However, in the event Buyer seeks to obtain transition services from the Transition Employees for a period of up to 120 days after the Closing Date (the “Transition Period”) (as may be mutually extended by the parties) and such Transition Employees agree, then this subsection shall govern the terms thereof. Buyer and Parent shall analyze the revenue rate per month per person for the Transition Employees’ services and the direct (including salary, bonus allocation and benefits) and indirect costs and expenses per month per person, including customary business expenses, such as client travel, lodging, meals and incidentals as well as the Transition Employees’ housing, car, driver and other out of pocket expatriate expenses, if any, and other indirect costs for the Transition Period. Once the chief financial officers for Buyer and Parent, or their designees, reach agreement on such revenue and cost per Transition Employee, the difference or net profit/loss will be shared equally by Buyer and Seller. Buyer will be entitled to, and will assume, any obligations related to the Transition Employees’ housing or cars to the extent they extend beyond the end of the Transition Period and are no longer needed by such Transition Employees. Buyer and Parent will cooperate on visa/business license issues for the Transition Employees, including potentially retaining such people as employees or contractors of Buyer’s local entity on a temporary basis; and conversely potentially retaining someone on Schedule 1.05(c) as an employee or contractor of Seller (or an Affiliate) on a temporary basis. Seller or Parent shall pay for the travel and moving expenses of the Transition Employees to return to their home office at the end of the Transition Period.

     (b) The Buyer Indemnitees shall not be entitled to recover under Section 8.02 unless a claim has been asserted by written notice, specifying the details of the alleged misrepresentation, breach of warranty or covenant or other basis for indemnification with reasonable particularity, the sections of this Agreement alleged to have been breached and/or supporting the claim, a good faith estimate of the Damages claimed, and the relevant facts (a “Certificate”), delivered to Seller on or prior to the expiration of the relevant survival period specified in Section 10.01. Upon delivery of a Certificate by Buyer to Seller, Buyer shall be entitled at its discretion to withhold, up to the amount of the Damages specified in such Certificate and net of that portion of the Escrow Amount which is not subject to a claim for indemnification under Section 8.02, any amount payable to Seller under Section 1.02(b)(v). However, in the event that Seller shall object to all or any portion of such Damages and it is ultimately determined that Buyer is not entitled to indemnification in respect of all or any portion of the amount withheld, then Buyer shall, within five Business Days of such determination, pay to Seller the unduly withheld amount, plus interest thereon from the date such amount should have been paid under Section 1.02(b)(v) hereof until the date such amount is paid to Seller at a rate equal to (i) the prime rate as published in The Wall Street Journal on the date such payment should have been made under Section 1.02(b)(v) plus (ii) three percent (3%).

     (c) The Buyer Indemnitees shall not be entitled to recover under Section 8.02 for the amount of any Damages in excess of Two Million Five Hundred Thousand U.S. Dollars ($2,500,000); provided, however, that the Buyer Indemnitees shall be entitled to recover under Section 8.02 for an aggregate cumulative amount of Ten Million U.S. Dollars ($10,000,000) for Damages sustained or incurred by any Buyer Indemnitee as a result of, arising out of, or by virtue of any Pre-Closing Liability; and, provided further, that this Section 8.03(c) shall not apply in respect of any breach of any representation or warranty made in Article III or Section 4.01, 4.02, 4.03, 4.04 or 4.12. For purposes of clarification, Buyer and Seller agree that any Damages eligible for indemnification under Section 8.02 shall first be satisfied from the Escrow Amount and any additional Damages eligible for indemnification under Section 8.02 are unsecured claims (subject to Buyer’s rights under Section 8.03(b) to withhold amounts from any Contingent Payment).

     (d) The Buyer Indemnitees shall not be entitled to recover under Section 8.02:

     (i) with respect to consequential damages of any kind, damages consisting of business interruption or lost profits (regardless of the characterization thereof), damages for diminution in value of the Companies and/or their subsidiaries, damages computed on a multiple of earnings or similar

basis, and indirect, special, exemplary and punitive damages, except for any such damages suffered or incurred by a third party for which a Buyer Indemnitee is otherwise entitled to recover under Section 8.02;

     (ii) with respect to any representation and warranty in respect of which Buyer was obligated to notify Seller pursuant to Section 7.02 and failed to do so, provided that this Section 8.03(d)(ii) shall not limit Buyer’s right to recover under Section 8.02(b), (c), or (d);

     (iii) with respect to the failure to obtain any consent referenced in Section 2.01(c) or (d) hereof;

     (iv) to the extent of any amount actually recovered in respect of the claim under insurance held by or for the Companies or their subsidiaries (net of commercially reasonable deductible amounts), other than any such recovery under any self-insurance or insurance held through a captive insurer affiliated with Buyer; and

     (v) to the extent the liability in question, taken together with all similar liabilities, does not exceed the amount of any reserves with respect to such matters which are taken into account in the calculation of the Working Capital Amount.

     (e) The amount of any recovery by the Buyer Indemnities pursuant to Section 8.02 shall be computed net of any Tax benefit actually realized by the Buyer Indemnitees that is attributable to such Damages. To the extent that any such Tax benefit is actually realized following the date that an indemnity payment is made hereunder, then no later than 30 days after a Tax Return has been filed that first takes into account the deduction, loss or other Tax attribute generated as a result of the Damage that gave rise to such indemnity payment, the Buyer Indemnitee shall pay to the Seller in immediately available funds the amount of the Tax benefit that is actually realized as a result of the Damage that gave rise to such indemnification (i.e., the reduction in Taxes that would have been otherwise due and payable but for the deduction, loss or other Tax attribute generated as a result of the Damages that gave rise to such indemnification), provided, that the Seller shall promptly repay to the Buyer Indemnitee the amount of any such payment to the extent that the amount of such Tax benefit is subsequently reduced or denied as a result of an adjustment to the Buyer Indemnitee’s liability for Taxes. In the event that a deduction, loss or other Tax attribute does not result in a Tax benefit actually realized, this Section 8.03(e) shall continue to apply until such deduction, losses or other Tax attribute results in a Tax benefit actually realized or the deduction, losses or other tax attribute expires without being utilized. Solely for purposes of calculating Damages payable to the Buyer Indemnitees pursuant to this Section 8.03(e), a Tax benefit shall be deemed to be actually realized if a deferred tax asset reflected on the Latest Balance Sheet (which was not taken into account in the Working Capital Amount), available at the time of the calculation contemplated hereunder, is utilized by Buyer or its Affiliates in respect of such Damages.

     (f) The Buyer Indemnitees shall not be entitled to recover under Section 8.02 with respect to a Tax matter for which a claim has been asserted to the extent such matter

has been taken into account in the calculation of the Working Capital Amount, provided that such reserves have been maintained in the ordinary course of business.

          8.04 Buyer’s Indemnification Obligations. Subject to the provisions of Sections 8.05, 8.07, 8.08 and 8.09, Buyer shall indemnify, save and keep Seller and its Affiliates (“Seller Indemnitee”) harmless against and from all Damages sustained or incurred by any Seller Indemnitee, as a result of or arising out of or by virtue of:

          (a) any inaccuracy in or breach of any representation or warranty made by Buyer to Seller herein, in any Buyer Ancillary Agreement or in any closing document delivered to Seller in connection herewith;

          (b) any breach by Buyer or any of its Affiliates of, or failure by Buyer or any of its Affiliates to comply with, any of its covenants or obligations under this Agreement (including without limitation its obligations under this Article VIII) or under any Buyer Ancillary Agreement; or

          (c) the acts or omissions of Buyer or the Companies (or of any of their Affiliates with respect to the Companies) after the Effective Time, any Post-Closing Liabilities and Buyer’s and its Affiliates’ operation of the Companies after the Effective Time.

          8.05 Limitation on Buyer’s Indemnification Obligations. Except with respect to claims made under Section 8.04(b) with respect to a breach of, or failure to comply with, Section 7.04, 10.07 or 10.11, Buyer’s obligations pursuant to the provisions of Section 8.04 are subject to the following limitations:

          (a) The Seller Indemnitees shall not be entitled to recover under Section 8.04 unless a claim has been asserted by written notice, specifying the details of the alleged misrepresentation, breach of warranty or covenant or other basis for indemnification with reasonable particularity, the sections of this Agreement alleged to have been breached and/or supporting the claim, a good faith estimate of the Damages claimed, and the relevant facts, delivered to Buyer on or prior to the expiration of the relevant survival period specified in Section 10.01.

          (b) The Seller Indemnitees shall not be entitled to recover under Section 8.04 for the amount of any Damages in excess of Two Million Five Hundred Thousand U.S. Dollars ($2,500,000); provided, however, that (i) this Section 8.05(b) shall not apply in respect of (A) any breach of any representation or warranty made in Article V or (B) any claims made under Section 8.04(c), and (ii) a claim by Seller for payment of the Contingent Payment, if any, payable to Seller under Section 1.02(b)(v) shall not be counted towards such limit.

          (c) The Seller Indemnitees shall not be entitled to recover under Section 8.04:

               (i) with respect to consequential damages of any kind, damages consisting of business interruption or lost profits (regardless of the

characterization thereof), damages for diminution in value of Seller or Parent and/or their subsidiaries, damages computed on a multiple of earnings or similar basis, and indirect, special, exemplary and punitive damages, except for any such damages suffered or incurred by a third party for which such Seller Indemnitee is otherwise entitled to recover under Section 8.04;

               (ii) with respect to the failure to obtain any consent referenced in Section 2.02(d) hereof; and

               (iii) to the extent of any amount actually recovered in respect of the claim under insurance held by or for Seller or Parent or their subsidiaries (net of commercially reasonable deductible amounts), other than any such recovery under any self-insurance or insurance held through a captive insurer affiliated with Seller.

     (d) The amount of any recovery by the Seller Indemnities pursuant to Section 8.04 shall be computed net of any Tax benefit actually realized by the Seller Indemnitees that is attributable to such Damages. To the extent that any such Tax benefit is actually realized following the date that an indemnity payment is made hereunder, then no later than 30 days after a Tax Return has been filed that first takes into account the deduction, loss or other Tax attribute generated as a result of the Damage that gave rise to such indemnity payment, the Seller Indemnitee shall pay to the Buyer in immediately available funds the amount of the Tax benefit that is actually realized as a result of the Damage that gave rise to such indemnification (i.e., the reduction in Taxes that would have been otherwise due and payable but for the deduction, loss or other Tax attribute generated as a result of the Damages that gave rise to such indemnification), provided, that the Buyer shall promptly repay to the Seller Indemnitee the amount of any such payment to the extent that the amount of such Tax benefit is subsequently reduced or denied as a result of an adjustment to the Seller Indemnitee’s liability for Taxes. In the event that a deduction, loss or other Tax attribute does not result in a Tax benefit actually realized, this Section 8.05(d) shall continue to apply until such deduction, losses or other Tax attribute results in a Tax benefit actually realized or the deduction, losses or other tax attribute expires without being utilized.

          8.06 Cooperation. Subject to the provisions of Section 8.07, the Indemnifying Party shall have the right, at its own expense, to participate in the defense of any Third Party Claim, and if said right is exercised, the parties shall cooperate in the investigation and defense of said Third Party Claim.

          8.07 Third Party Claims. Forthwith following the receipt of notice of a Third Party Claim, the party receiving the notice of the Third Party Claim shall notify the other party of its existence setting forth with reasonable specificity the facts and circumstances of which such party has received notice, and if the party giving such notice is an Indemnified Party, specifying the basis hereunder upon which the Indemnified Party’s claim for indemnification is asserted; provided, however that any failure or delay to deliver such notice shall only affect the Indemnified Party’s rights under this Article VIII to the extent that such failure or delay prejudices the Indemnifying Party’s ability to satisfactorily defend or settle the Third Party

           Claim. The Indemnified Party may, upon reasonable notice, tender the defense of a Third Party Claim to the Indemnifying Party. If:

          (a) the defense of a Third Party Claim is so tendered by the Indemnified Party and within 30 days thereafter such tender is accepted without qualification by the Indemnifying Party; or

          (b) within 30 days after the date on which written notice of a Third Party Claim has been given by the Indemnified Party pursuant to this Section 8.07, the Indemnifying Party shall have acknowledged in writing without qualification its indemnification obligations as provided in this Article VIII to the Indemnified Party and shall have accepted the defense thereof;

then, except as herein provided, the Indemnified Party shall not, and the Indemnifying Party shall, have the right to contest, defend, litigate or settle such Third Party Claim. The Indemnified Party shall have the right to be represented by counsel at its own expense in any such contest, defense, litigation or settlement conducted by the Indemnifying Party, provided that the Indemnified Party shall be entitled to reimbursement therefor if the Indemnifying Party shall lose its right to contest, defend, litigate and settle the Third Party Claim as herein provided or if the named parties to any such action (including any impleaded parties) include both the Indemnified Party and the Indemnifying Party and such Indemnified Party shall have been advised in writing by counsel that there are one or more material legal defenses available to either party and that the assertion (or nonassertion) by the Indemnifying Party of any of such defenses will be adverse to the interests of the Indemnified Party. The Indemnifying Party shall lose its right to contest, defend, litigate and settle the Third Party Claim if it shall fail to contest, in a commercially reasonable manner and in a commercially reasonable time frame, the Third Party Claim. So long as the Indemnifying Party has not lost its right and/or obligation to contest, defend, litigate and settle as herein provided, the Indemnifying Party shall have the exclusive right to contest, defend and litigate the Third Party Claim and shall have the exclusive right, in its discretion exercised in good faith, and upon the advice of counsel, to settle any such matter, either before or after the initiation of litigation, at such time and upon such terms as it reasonably deems fair and reasonable, provided that at least ten (10) days prior to any such settlement, written notice of its intention to settle shall be given to the Indemnified Party and provided further that, unless otherwise approved in advance by the Indemnified Party in writing, any such settlement shall (i) include a full unconditional release of the Indemnified Party and its Affiliates for all claims related to the applicable Third Party Claim, (ii) not provide for any remedy other than the payment of damages which are fully indemnified by the Indemnifying Party hereunder, and (iii) not involve any admission of fault by the Indemnified Party or any of its Affiliates. Notwithstanding the foregoing, Seller may not settle or otherwise dispose of (nor permit any of its Affiliates to settle or otherwise dispose of) any matter involving the Tax liability of a Company (other than the Spanish Tax Claims) without the prior written consent of Buyer (which shall not be unreasonably withheld). All expenses (including without limitation attorneys’ fees) incurred by the Indemnifying Party in connection with the foregoing shall be paid by the Indemnifying Party. No failure by an Indemnifying Party to acknowledge in writing its indemnification obligations under this Article VIII shall relieve it of such obligations to the extent they exist. If an Indemnified Party is entitled to indemnification against a Third Party Claim, and the Indemnifying Party fails to accept a tender of, or assume, the defense of a Third Party Claim pursuant to this Section 8.07, or if, in accordance with the foregoing, the

Indemnifying Party shall lose its right to contest, defend, litigate and settle such a Third Party Claim, the Indemnified Party shall have the right, without prejudice to its right of indemnification hereunder, in its discretion exercised in good faith and upon the advice of counsel, to contest, defend and litigate such Third Party Claim, and may settle such Third Party Claim, eit her before or after the initiation of litigation, at such time and upon such terms as the Indemnified Party deems fair and reasonable, provided that at least ten (10) days prior to any such settlement, written notice of its intention to settle is given to the Indemnifying Party. If, pursuant to this Section 8.07, the Indemnified Party so contests, defends, litigates or settles a Third Party Claim for which it is entitled to indemnification hereunder, the Indemnified Party shall be reimbursed by the Indemnifying Party for the reasonable attorneys’ fees and other expenses of contesting, defending, litigating and/or settling the Third Party Claim which are incurred from time to time, forthwith following the presentation to the Indemnifying Party of itemized bills for said attorneys’ fees and other expenses.

          8.08 Calculation of Damages. Neither a Buyer Indemnitee nor a Seller Indemnitee shall be entitled to recover any amount due to it under this Article VIII more than once in respect of the same Damage.

          8.09 Indemnification Exclusive Remedy. Except with respect to Sections 10.07 and 10.08 or in the case of fraud, indemnification pursuant to the provisions of this Article VIII shall be the exclusive remedy of the parties for any misrepresentation or breach of any warranty or covenant contained herein or in any closing document executed and delivered pursuant to the provisions hereof. Without limiting the generality of the preceding sentence, no legal action sounding in tort or strict liability may be maintained by any party.

          8.10 Tax Effect of Indemnification Payments. All indemnity payments made pursuant to this Agreement shall be treated for all Tax purposes as adjustments to the Purchase Price.

ARTICLE IX
TERMINATION

          9.01 Termination. This Agreement may be terminated at any time prior to the Closing:

          (a) by the mutual consent of Buyer and Seller;

          (b) by Buyer, if there has been a material violation or breach by Seller of any covenant, representation or warranty contained in this Agreement which has prevented the satisfaction of any condition to the obligations of Buyer at the Closing and such violation or breach has not been waived by Buyer or, in the case of a covenant breach, cured by Seller within ten days after written notice thereof from Buyer;

          (c) by Seller, if there has been a material violation or breach by Buyer of any covenant, representation or warranty contained in this Agreement which has prevented the satisfaction of any condition to the obligations of Seller at the Closing and such violation or breach has not been waived by Seller or, with respect to a covenant breach,

cured by Buyer within ten days after written notice thereof by Seller (provided that the failure to deliver the Purchase Price at the Closing as required hereunder shall not be subject to cure hereunder unless otherwise agreed to in writing by Seller); or

          (d) by either Buyer or Seller if the transactions contemplated hereby have not been consummated by the close of business on September 1, 2006; provided that neither Buyer nor Seller shall be entitled to terminate this Agreement pursuant to this Section 9.01(d) if such Person’s willful breach of this Agreement has prevented the consummation of the transactions contemplated hereby.

          9.02 Effect of Termination. In the event of termination of this Agreement by either Buyer or Seller as provided above, the provisions of this Agreement shall immediately become void and of no further force and effect (other than this Section 9.02 and Article XII hereof which shall survive the termination of this Agreement), and there shall be no liability on the part of either Buyer or Seller to one another, except for willful breaches of this Agreement prior to the time of such termination.

ARTICLE X
ADDITIONAL COVENANTS

          10.01 Survival. The representations and warranties set forth in this Agreement and in any Seller Ancillary Agreements, Buyer Ancillary Agreements or certificates delivered at the Closing in connection with this Agreement shall be made as of the Closing and shall not continue thereafter, except that any claims for Damages made related thereto may be brought during (but only during) the following time frames pursuant to the terms of this Agreement.

          (a) Claims related to Article III or Section 4.01, 4.02, 4.03, 4.04, 4.12, 5.01, 5.02, 5.03, 5.04, 5.05 or 5.06 may only be brought prior to the tenth anniversary of the Closing Date.

          10.02 Disclosure Generally. If and to the extent any information required to be furnished in any Schedule or certificate is contained in this Agreement or in any Schedule attached hereto or certificate delivered pursuant hereto, such information shall be deemed to be included in any other Schedule attached hereto if and to the extent the relevance of such information to such other Schedule is reasonably apparent. The inclusion of any information in any Schedule attached hereto shall not be deemed to be an admission or acknowledgment by Seller, in and of itself, that such information is material to or outside the ordinary course of the business of the Companies.

          10.03 Acknowledgment by Buyer. Buyer acknowledges that it has conducted to its satisfaction, an independent investigation of the financial condition, results of operations, assets, liabilities, properties and projected operations of the Companies and, in making its determination to proceed with the transactions contemplated by this Agreement, Buyer has relied on the results of its own independent investigation and the representations and warranties of Seller expressly and specifically set forth in this Agreement, including the Schedules and the certificate under Section 2.01(f)(i). SUCH REPRESENTATIONS AND WARRANTIES BY SELLER CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF SELLER TO BUYER IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY, AND BUYER UNDERSTANDS, ACKNOWLEDGES AND AGREES THAT ALL OTHER REPRESENTATIONS AND WARRANTIES OF ANY KIND OR NATURE EXPRESSED OR IMPLIED (INCLUDING, BUT NOT LIMITED TO, ANY RELATING TO THE FUTURE OR HISTORICAL FINANCIAL CONDITION, RESULTS OF OPERATIONS, ASSETS OR LIABILITIES OF THE COMPANIES) ARE SPECIFICALLY DISCLAIMED BY SELLER.

          10.04 Arbitration Procedure.

          (a) Buyer and Seller agree that the arbitration procedure set forth below shall be the sole and exclusive method of resolving and remedying any and all disputes regarding claims for money damages based upon, arising out of or in any way connected with the Agreement or the transactions contemplated herein (the “Disputes”). Nothing in this Section 10.04 shall prohibit a party from instituting litigation to enforce any Final Determination (as

           defined below). The parties hereby agree and acknowledge that, except as otherwise provided in this Section 10.04 or in the commercial Arbitration Rules of the AAA as in effect from time to time, the arbitration procedures and any Final Determination hereunder shall be governed by and shall be enforced pursuant to the Uniform Arbitration Act as in effect in the State of Delaware, USA.

          (b) In the event that any party asserts that there exists a Dispute, such party shall deliver a written notice to each other party involved therein specifying the nature of the asserted Dispute and requesting a meeting to attempt to resolve the same. If no such resolution is reached within 45 days after such delivery of such notice, the party delivering such notice of Dispute may, within 75 days after delivery of such notice, commence arbitration hereunder by delivering to each other party involved therein a notice of arbitration (a “Notice of Arbitration”). Such Notice of Arbitration shall specify the matters as to which arbitration is sought, the nature of any Dispute, the claims of each party to the arbitration and the amount and nature of damages or other relief sought to be recovered as a result of any alleged claim and any other matters required by the Commercial Arbitration Rules of the AAA as in effect from time to time to be included therein.

          (c) Buyer and Seller each shall select one arbitrator expert in the subject matter of the Dispute (the arbitrators so selected shall be referred to herein as “Buyer’s Arbitrator” and “Seller’s Arbitrator,” respectively). In the event that either party fails to select an arbitrator as set forth herein within 30 days after the delivery of a Notice of Arbitration, then the matter shall be resolved by the arbitrator selected by the other party. Seller’s Arbitrator and Buyer’s Arbitrator shall select a third independent, neutral arbitrator expert in the subject matter of the Dispute, and the three arbitrators so selected shall resolve the Dispute according to the procedures set forth in this Section 10.04. If Seller’s Arbitrator and Buyer’s Arbitrator are unable to agree on a third arbitrator within 20 days after their selection, Seller’s Arbitrator and Buyer’s Arbitrator shall each prepare a list of three independent arbitrators. Seller’s Arbitrator and Buyer’s Arbitrator shall each have the opportunity to designate as objectionable and eliminate one arbitrator from the other arbitrator’s list within ten days after submission thereof, and the third arbitrator shall then be selected by lot from the arbitrators remaining on the lists submitted by Seller’s Arbitrator and Buyer’s Arbitrator.

          (d) The arbitrators selected pursuant to paragraph (c) shall determine the allocation of the costs and expenses of arbitration based upon the percentage which the portion of the contested amount not awarded to each party bears to the amount actually contested by such party. For example, if Buyer submits a claim for $1,000 and if Seller contest only $500 of the amount claimed by Buyer, and if the arbitrators ultimately resolves the dispute by awarding Buyer $300 of the $500 contested, then the costs and expenses of arbitration will be allocated 60% (i.e., 300 of 500) to Seller according to their respective Pro Rata Shares and 40% (i.e., 200 of 500) to Buyer.

          (e) The arbitration shall be conducted in New York, New York, under the Commercial Arbitration Rules of the AAA as in effect from time to time, except as modified by the agreement of Buyer and Seller. The arbitrators shall conduct the arbitration such that a final result, determination, finding, judgment and/or award (the “Final Determination”) is made or

30

rendered as soon as practicable, but in no event later than 120 days after the delivery of the Notice of Arbitration nor later than ten days following completion of the arbitration. The Final Determination shall be made in writing, shall state the basis for such determination and shall be agreed upon and signed by the sole arbitrator or by at least two of the three arbitrators (as the case may be). The Final Determination shall be final and binding on all parties, and there shall be no right of appeal from or reexamination of the Final Determination, except for fraud, perjury, evident partiality or misconduct by an arbitrator prejudicing the rights of any party and to correct manifest clerical errors.

          (f) Buyer and Seller may enforce any Final Determination in any state or federal court having jurisdiction over the Dispute. For the purpose of any action or proceeding instituted with respect to any Final Determination, each party hereto hereby irrevocably submits to the jurisdiction of such courts, irrevocably consents to the service of process by registered mail or personal service and hereby irrevocably waives, to the fullest extent permitted by law, any objection which it my have or hereafter have as to personal jurisdiction, the laying of the venue of any such action or jurisdiction, the laying of the venue of any such action or proceeding brought in any such court and any claim that any such action or proceeding brought in any court has been brought in an inconvenient form.

          (g) If any party shall fail to pay the amount of any damages, if any, assessed against it within 20 days after the delivery to such party of such Final Determination, the unpaid amount shall bear interest from the date of such delivery at the lesser of (i) the prime rate of interest announced by Citibank N.A., in effect from time to time (which rate shall be adjusted on the effective date of each change in such prime rate) and (ii) the maximum rate permitted by applicable usury laws. Interest on any such unpaid amount shall be compounded semi-annually, computed on the basis of a 360-day year consisting of twelve 30-day months and shall be payable on demand. In addition, such party shall promptly reimburse the other party from any and all costs and expenses of any nature or kind whatsoever (including reasonable legal fees and expenses) incurred in seeking to collect such damages or to enforce any Final Determination.

          10.05 Tax Matters.

          (a) Seller shall cause the Companies to prepare and file on a timely basis all Tax Returns of the Companies due on or prior to the Effective Date. Seller shall, at the sole cost and expense of the Companies, prepare (and, to the extent permitted by law, timely file) all income Tax Returns of the Companies that are due after the Effective Date, but which relate to taxable periods ending on or prior to the Effective Date (“Pre-Closing Income Tax Returns”). Any such Tax Returns prepared by Seller shall be prepared on a basis consistent with existing procedures and practices of the Companies. To the extent any Pre-Closing Income Tax Return is required to be filed by a Company, Seller shall deliver such return to the Company no later than ten (10) business days prior to the date such return is due and Buyer shall cause the Company to file such Tax Return on a timely basis. Buyer shall cause the Companies to prepare and file on a timely basis all Tax Returns of the Companies (other than Pre-Closing Income Tax Returns) due after the Effective Date that relate to taxable periods ending after the Effective Date and such Tax Returns shall be prepared in a manner consistent with existing procedures and practices of the Companies. Seller and Buyer shall not amend a Tax Return (or extend the applicable statute of limitations) for any tax years ending on or before the Effective

31

Date without the prior written permission of the other party (which will not be unreasonably withheld), except as otherwise required by applicable law.

          (b) Buyer, the Companies (through Buyer’s control) and Seller shall provide each other with notice of and such assistance as may reasonably be requested by the others in connection with the preparation of any return or report of Taxes, any audit or other examination by any taxing authority, or any judicial or administrative proceedings relating to liabilities for Taxes. Such assistance shall include making employees available on a mutually convenient basis to provide additional information or explanation of material provided hereunder, shall include providing copies of relevant tax returns and supporting material and shall include executing reasonably prepared documents related to the Companies for periods prior to the Effective Date that Seller has liability therefor. The party requesting assistance hereunder shall reimburse the assisting party for reasonable out-of-pocket expenses incurred in providing assistance. Buyer, the Companies (through Buyer’s control) and Seller will retain for the full period of any statute of limitations or applicable law (and any further period during which a claim is outstanding), and provide the others, with any records or information which may be relevant to such preparation, audit, examination, proceeding or determination.

          (c) All federal, state, local, foreign and other transfer Tax applicable to, imposed upon or arising out of the transfer of the Shares shall be borne equally by Seller and Buyer.

          (d) All refunds, plus interest thereon, for Taxes for periods ending on or before the Effective Date shall be property of Seller and such refunds, plus any interest earned in connection with the refund, shall be paid to Seller by Buyer or the Companies promptly upon receipt. All other refunds for Taxes for periods after the Effective Date, plus interest thereon, shall be the property of Buyer and the Companies and shall be paid to Buyer or the Companies by Seller promptly upon receipt if so received by Seller.

     In consideration of the execution by Buyer and Seller of the foregoing Stock Purchase Agreement between Seller and Buyer (the “Agreement”), the undersigned does hereby absolutely, irrevocably and unconditionally guarantee to Buyer full and prompt payment and performance of all of the obligations and agreements of Seller as set forth in the Agreement and in the other documents executed by Seller in connection therewith, subject in each case to the limitations set forth therein and at law (which obligations, subject to such limitations, are referred to herein as the “Obligations”), in each case as if the Obligations were direct and primary obligations of the undersigned, and to pay to Buyer, when due or upon demand thereafter, any amounts then owing by Seller to Buyer in respect of the Obligations in the event that Seller fails to make such payment. The guaranty evidenced hereby is a guaranty of payment and performance and not a guaranty of collection. This guaranty shall be effective regardless of the solvency or insolvency of Seller or the undersigned, the extension or modification of the indebtedness of Seller or the undersigned or the reincorporation, reorganization, merger, or consolidation of Seller or the undersigned or any change in the composition of, nature, personnel or location of Seller or the undersigned.

     The undersigned hereby waives diligence, presentment, demand for payment, filing of claims with a court in the event of receivership or bankruptcy of Seller or protest or notice with respect to the Obligations, and all demands whatsoever, and the undersigned shall not require that the same be made on Seller as a condition precedent to the undersigned’s obligations hereunder.

     This Guaranty shall be binding upon the undersigned and upon the successors and assigns of the undersigned and shall inure to the benefit of Buyer, its Affiliates, successors, legal representatives and permitted assigns. All references to the singular shall be deemed to include the plural where the context so requires. Nothing in this Guaranty, express or implied, is intended to confer on any Person other than the undersigned and the parties to the Agreement, and their respective Affiliates, and their respective successors, legal representatives and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Guaranty.

This Guaranty shall continue until all of the terms, covenants and conditions of the Agreement have been fully performed by Seller, but shall then terminate.
