For a Period commencing on the Closing Date and ending on the date that is 60 months after the Closing Date, the Seller agrees that neither it, nor any affiliate of Seller (including any SPR Company) nor any entity which has a majority of its equity interest owned directly or indirectly by the members of Seller who as of the date hereof own a majority of the membership interests of Seller will (i) engage, either directly of indirectly, in any capacity

in, or have any ownership or economic interest in or control over, any business which (A) is similar to or in competition with the business conducted by Support Services Company or (B) primarily engages in the business of providing off-hours preliminary imaging reads, or (ii) directly or indirectly encourage any customer of the Business to cease doing business with any of the SPR Companies or decrease the amount of business it is doing with any of the SPR Companies; provided, however, that the provisions of clause A shall cease to apply if the Administrative Support Services Agreements are terminated in accordance with their terms.

5.15 Employee and Employee Plan Matters. Seller represents, warrants and covenants to Buyer as follows:

(a) The Seller has taken (or caused to be taken) all necessary actions so that coverage under any Employee Plan providing group medical coverage to Employees and their covered spouses and dependents will not terminate until 11:59 p.m. on the last day of the month during which the Closing Date occurs. Notwithstanding the foregoing, the Seller has taken (or caused to be taken) all necessary actions so that each Acquired Company’s status as a participating employer in each Employee Plan of which the Acquired Company is not the plan sponsor will be terminated effective on the day immediately after the Closing Date. The list of such Employee Plans is set forth on Section 5.15 of the Disclosure Letter. The Parties agree that, except as provided in Item #2 of Schedule B, the Seller and its ERISA Affiliates (other than the Acquired Companies) retain all liabilities with respect to each such Employee Plan and the Acquired Companies, the Buyer and the Buyer’s affiliates will not have any obligations or liabilities under such Employee Plans.

(b) The Seller has taken, or caused to be taken, all necessary action (i) so that the benefits of each Employee who participates in any Employee Plan that is a qualified retirement plan subject to Section 401(a) of the Code are fully vested as of the Closing Date and (ii) to ensure that each Employee is eligible to receive a distribution immediately after the Closing Date of his or her account balance plan under any Employee Plan that is a qualified retirement plan; provided, that Seller was not required to take any actions contemplated in this Section 5.15(b) on behalf of any Employee who is a “highly compensated” employee (as defined in Code Section 414(q)(1)) to the extent that doing so could cause the qualified retirement plan to fail discrimination testing.

(c) The Parties agree that with respect to any Employee of an Acquired Company who, as of the Closing Date, is disabled (within the meaning of the Employee Plan providing long-term disability benefits) or is otherwise eligible (or within the waiting periods) for disability benefits, the Seller and its ERISA Affiliates (other than the Acquired Companies) retain all liabilities for short-term and long-term disability benefits for such Employee, but only to the extent the applicable Employee(s) is eligible for benefits under any of the Employee Plans.

(d) The Parties agree that with respect to any former Employee of an Acquired Company whose employment was terminated by the Acquired Company on or prior to the Closing Date or whose employment was transferred from the Acquired Company to the Seller or any affiliate of Seller on or prior to the Closing Date:

(i) the Seller and its ERISA Affiliates (other than the Acquired Companies) retain responsibility for benefits including, but not limited to, severance benefits, short-term disability, long-term disability, medical, dental and COBRA continuation coverage and employment-related claims to which such Employee is entitled, and

(ii) the Acquired Companies, the Buyer and the Buyer’s affiliates will not have any obligations or liabilities with respect to such Employee until such time (if any) that the Employee returns to active employment with the Acquired Company.

(e) Nothing contained in this Agreement or in any other agreement or document executed or delivered by Buyer in connection with the transactions contemplated hereby will be deemed or construed to constitute a commitment of Buyer, or the Acquired Companies to retain any employees of the Acquired Companies for any particular period of time or at any particular rate of compensation on or after the Closing Date or, except as provided in Section 5.16, to continue any plan, arrangement or other commitment of any kind relating to any employee benefits, welfare, insurance, incentive/bonus plans or compensation, perquisites or similar matters of any kind or nature for any particular period of time or at any particular level, on or after the Closing Date.

5.16 Buyer Benefit Plans. As of the Closing Date, Buyer will make the benefit plans set forth on Schedule 5.16 available to the employees of the Acquired Companies. Buyer will keep such plans in place in accordance with their present terms at least until December 31, 2008. In addition, Buyer will institute for the employees of the Acquired Companies, upon Closing, a special bonus program whereby each employee of an Acquired Company will be paid a cash bonus at the end of each calendar quarter that is equal to 10% of the wages or salary paid to such employee during such calendar quarter. This bonus program will remain in effect for one year such that the maximum payable to any employee under such program will be 10% of such employee’s annual wages or salary. In order to receive a bonus for a calendar quarter, an employee of an Acquired Company must be employed by an Acquired Company on the date that the bonus is paid. Buyer represents that its vacation plan is the only benefit plan it currently has in place where disregarding an employee’s service time with an Acquired Company would affect the benefits the employee would receive under Buyer’s benefit plans. For purposes of Buyer’s vacation plan and any future plan of Buyer in which Buyer is permitted to grant prior service credit and in which prior service credit affects the benefits available under such plan, Buyer will give each employee of the Acquired Companies prior service credit for such employee’s period of employment with the Acquired Companies prior to the Closing Date. Subject to Buyer’s commitment set forth in this Section 5.16, Buyer expressly reserves the right to amend, modify and/or terminate any of its benefit plans after the Closing Date, although it has no current plan to do so.

5.17 Life Insurance and Long-Term Disability Insurance. Buyer will research whether it can make life insurance and long-term disability insurance available to employees at no cost to Buyer and if so, will make such coverage available to employees at the employees’ cost within a reasonable period of time.

5.18 Warrant. At the Closing, Buyer will grant to SPRPA a warrant in the form attached hereto as Exhibit B which will entitle SPRPA to purchase 300,000 shares of common stock of Buyer a price equal to the fair market value of a share of Buyer’s common stock as of the close of business on the trading day prior to the Closing Date and will have an expiration date that is ten (10) years after the Closing Date.

At the Closing, by virtue of this Agreement and as partial security for indemnity obligations provided for in Article VIII hereof, Buyer shall pay to the Escrow Agent a portion of the Cash Consideration equal to the Escrow Amount (together with interest or earnings thereon the “Escrow Fund”) to be held in escrow pursuant to the Escrow Agreement. The Escrow Fund shall be available as a non-exclusive source to compensate Buyer for Losses incurred by Buyer, and/or each of Buyer’s officers, directors, employees, contractors, agents, successors, stockholders, assigns and affiliates pursuant to the indemnification provisions set forth in Article VIII hereof pursuant to the Escrow Agreement.

ARTICLE VIII

SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

8.1 Survival of Representations and Warranties. The representations and warranties of the Acquired Companies and Seller contained in this Agreement, or in any certificate or other instrument delivered pursuant to this Agreement, shall terminate on the 24-month anniversary of the Closing Date, provided, however, that the representations and warranties contained in

Section 3.3 (Capitalization) and Section 3.18 (Tax Matters) (such representations and warranties, the “Unlimited Representations”) shall survive until 90 days after the expiration of the applicable statutes of limitation period, and that any breach of a representation or warranty resulting from fraud, intentional misrepresentation or knowing and willful misconduct shall survive indefinitely. The representations and warranties of Buyer contained in this Agreement, or in any certificate or other instrument delivered pursuant to this Agreement, shall terminate on the 24 month anniversary of the Closing Date. The covenants and agreements of the parties shall survive the Closing and any investigation at any time made and the consummation of the transactions contemplated hereby until fully performed, unless limited by their terms or purposes.

8.2 General Indemnification.

(a) Seller (the “Seller Indemnifying Party”) hereby agrees to indemnify and hold harmless Buyer, the Acquired Companies (following the Closing) and each of their respective officers, directors, employees, contractors, agents, successors, stockholders, assigns and affiliates (collectively, the “Buyer Indemnified Parties”), against all claims, losses, liabilities, damages, deficiencies, costs and expenses, including reasonable attorneys’ fees and expenses of investigation and defense (hereinafter individually a “Loss” and collectively “Losses”) incurred or sustained by such Buyer Indemnified Parties directly or indirectly arising out of, relating to or resulting from (i) any breach or inaccuracy of a representation or warranty of the Acquired Companies and Seller or any other SPR Company contained in this Agreement or in any certificate delivered by the Acquired Companies or Seller pursuant to this Agreement (without giving effect, for purposes of determining the amount of any Losses related to any such breach or inaccuracy, to any limitation as to “materiality,” “material adverse effect,” “Material Adverse Effect” or similar qualifications set forth therein), (ii) any failure by the Acquired Companies or Seller or any other SPR Company to perform or comply with any covenant applicable to them contained in this Agreement, (iii) any Transaction Expenses of the Acquired Companies not paid by the Acquired Companies at or prior to the Closing, (iv) any actions, suits or proceedings brought by third parties (including any Government Authority), regardless if disclosed in the Disclosure Letter, related to the Business and related events occurring or actions taken on or prior to the Closing Date, (v) any of the liabilities expressly retained by Seller and its ERISA Affiliates under Section 5.15, (vi) any action taken by Seller, any Subsidiary of Seller, SPRPA or any Member of Seller that results in either of the Administrative Support Services Agreements being declared unenforceable or unlawful, in whole or in part or (vii) any of the matter set forth on Schedule B.

(b) Buyer hereby agrees to indemnify and hold harmless Seller and its officers, directors, employees, members, agents, successors, assigns and affiliates (collectively, the “Seller Indemnified Parties”), against all Losses incurred or sustained by the Seller Indemnified Parties arising out of, relating to or resulting from (i) any breach of a representation or warranty of Buyer contained in this Agreement (without giving effect, for purposes of determining the amount of any Losses relating to any such breach or inaccuracy, to any limitation as to “materiality”, “material adverse effect”, “Material Adverse Effect” or similar qualifications set forth therein), (ii) any failure of Buyer to perform or comply with any obligation applicable to Buyer contained in this Agreement, (iii) any Transaction Expenses of Buyer not paid by Buyer at or prior to the Closing, (iv) any actions, suits or proceeding brought by third parties (including any Government Authority), related to the business of the Acquired Company to the extent related to events occurring or action taken after the Closing Date, and (v) any liabilities assumed by Buyer related to the Business.

8.3 Limitation on Claims. None of the Buyer Indemnified Parties shall be entitled to seek recovery of Losses under clause (i) or clause (iv) of Section 8.2(a) unless and until Buyer has paid or incurred Losses in excess of $500,000 in the aggregate (the “Basket Amount”), in which case Buyer shall be entitled to recover all Losses so identified including the Basket Amount up to a maximum of Six Million Two Hundred Thousand Dollars ($6,200,000) (the “Rep Indemnity Cap”); provided, however, that neither the Basket Amount nor the Rep Indemnity Cap shall apply to any claims for Losses made by Buyer under clause (i) of Section 8.2(a) with respect to any breaches or inaccuracies of an Unlimited Representation and Buyer shall be entitled to indemnity for all of its Losses resulting from any breach or inaccuracy of an Unlimited Representation without regard to the Basket Amount or the Rep Indemnity Cap. For purposes of clarity, in no event shall the Basket Amount or Rep Indemnity Cap limit any party’s rights or obligations under any of the Collateral Agreements. All Losses shall be determined net of any insurance proceeds actually recovered (so long as recovered within three years after the applicable Losses are incurred) by the Indemnified Party with respect to the matter for which the Losses relate, and each Indemnified Party shall be obligated to use its commercially reasonable efforts to collect the maximum amount of any such available insurance proceeds. If any insurance recoveries are received by the Indemnified Party that are related to a matter for which Losses have been paid to the Indemnified Party by the Indemnifying Party (or from the escrow account referred to Article VII) under this Agreement, the Indemnified Party will pay such proceeds to the Indemnifying Party (or back into the escrow account) to the extent such proceeds reduce the amount of Losses sustained by the Indemnified Party with respect to such matter and for which the Indemnified Party has been indemnified by the Indemnifying Party together with all remaining aggregate Losses of the Indemnified Party if, after taking into consideration of the insurance recovery, the Indemnified Party’s aggregate Losses for which it has been indemnified hereunder plus any Losses for which it has asserted a claim for indemnity hereunder but which have not been paid because such claim is in dispute (a “Disputed Indemnity Claims”) are less than the Basket Amount; provided, however, if such aggregate amount is above the Basket Amount but if the amount of the Disputed Indemnity Claims were disregarded then the aggregate amount would be below the Basket Amount, the amount of the aggregate Losses without the Disputed Indemnity Claims shall be paid by Buyer into the escrow account established under the Escrow Agreement and such funds shall be considered part of the escrowed funds thereunder.

8.4 Tax Indemnification.

(a) The Seller Indemnifying Party shall be liable for, and shall indemnify and hold Buyer and the other Indemnified Parties harmless from, (i) all Taxes, including Seller Straddle Period Taxes (as defined below), of the Seller or the Acquired Companies, or relating to either of the Acquired Company’s operations, and attributable to any taxable period or portion of a period that ends on or before the Closing Date, (ii) all sales or use or transfer or transactional Taxes attributable to Seller’s sale of the Interests of the Acquired Companies, and (iii) any Taxes imposed on Seller by reason of income or gain recognition of Seller pursuant to the Seller’s sale of the Interests of the Acquired Companies. The Seller Indemnifying Party shall be responsible for reimbursing Buyer for such Taxes within 10 days of receipt of notice from Buyer of the amount of such Taxes. For purposes hereof, Taxes with respect to any taxable period that

includes (but does not end on) the Closing Date (a “Straddle Period”) shall be apportioned to the period ending on or before the Closing Date (the “Pre-Closing Period”) as follows: (i) the portion of any real, personal and intangible property Taxes (“Property Taxes”) equal to the amount of such Property Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Period and the denominator of which is the number of days in the Straddle Period; and (ii) any Taxes other than Property Taxes computed as if such Straddle Period ended on the Closing Date (the “Seller Straddle Period Taxes”).

(b) Buyer shall be liable for and shall indemnify and hold Seller and the other Seller Indemnified Parties harmless from all Taxes payable by the Buyer or Acquired Companies, or relating to either of the Acquired Company’s operations, and attributable to any taxable period or portion of a period that ends after the Closing Date (other than the amount of the Seller Straddle Period Taxes).

8.5 Order of Claims. The amount of any Losses (except in the case of fraud, intentional misrepresentation or willful misconduct) shall be recoverable by Buyer first through recourse to the Escrow Fund and, if the Escrow Fund is exhausted, then with full recourse to the Seller Indemnifying Party. In the case of fraud, intentional misrepresentation or willful misconduct, Buyer may seek any remedy to which it is entitled under law or equity.

8.6 Indemnification Procedure.

(a) If Buyer seeks indemnification under this Article VIII unrelated to a third party claim, Buyer shall deliver an Officer’s Certificate to the Seller. The Seller will either object to such claim by delivering written notice to Buyer specifying the basis for such objection within fifteen (15) days following receipt by the Seller of notice from Buyer regarding such claim or pay the Losses (either directly or by causing such amount to be released from the Escrow Fund) specified in such notice within such fifteen (15) day period; provided, however, that if Seller does neither, Buyer may treat such failure to act as an objection to such claim by Seller.

(b) If Seller seeks indemnification under this Article VIII unrelated to a third party claim, Seller shall deliver an Officer’s Certificate to Buyer. The Buyer will either object to such claim by delivering written notice to Seller specifying the basis for such objection within fifteen (15) days following receipt by the Buyer of notice from Seller regarding such claim or pay the Losses specified in such claim within such fifteen (15) day period; provided, however, that if Buyer does neither, Seller may treat such failure to act as an objection to such claim by Buyer.

(c) For the purposes hereof, “Officer’s Certificate” shall mean a certificate signed by any officer of the applicable party (a) stating that such or other Indemnified Party has paid, sustained, incurred, or properly accrued, or reasonably anticipates that it will have to pay, sustain, incur, or accrue Losses, and (b) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid, sustained, incurred or properly accrued, or the basis for such anticipated liability.

8.7 Resolution of Conflicts.

(a) If Seller or Buyer shall object in writing to any claim or claims made in any Officer’s Certificate to recover Losses within fifteen (15) days after delivery of such Officer’s Certificate (or be deemed to have so objected), Seller and Buyer shall attempt to resolve such claims through a mutually agreeable mediation process with a third party mediator, the costs of which mediation and mediator shall be shared equally. If the mediation is unsuccessful, either party shall have the right to commence legal action against the other party in connection with such claims.

8.8 Third-Party Claims.

(a) Notice of Third Party Claims. If any action, claim, suit, proceeding, arbitration, order, or governmental investigation or audit is filed or initiated by any third party (a “Third Party Claim”) against any Buyer Indemnified Parties or Seller Indemnified Parties, written notice of such Third Party Claim will be given to the party owing indemnity (an “Indemnifying Party”) as promptly as reasonably practicable (and in any event within ten (10) days after the service of the citation or summons); provided, however, that the failure of any Indemnified Party to give timely notice will not affect any rights to indemnification hereunder except to the extent that the Indemnifying Party is prejudiced or damaged by such failure to receive notice.

(b) Defense and Settlement by Indemnifying Party.

(i) After notice of a Third Party Claim is given under Section 8.8(a) and in the absence of a Conflict of Interest (as defined below), the Indemnifying Party give notice that it wishes to control defense of such Third Party Claim (which such notice must include an acceptance of indemnification responsibility for such claim by the Indemnifying Party in favor of the Indemnified Party), in which case the Indemnifying Party shall (A) take control of the defense and investigation of the Third Party Claim, (B) employ and engage attorneys of its own choice to handle and defend the Third Party Claim at the Indemnifying Party’s cost, risk and expense, which attorneys must be reasonably satisfactory to the indemnified party, and (C) subject to Section 8.8(b)(ii) below, compromise or settle the Third Party Claim; provided, however, that the Indemnified Party shall have the right to participate in the defense of any Third Party Claim at its own expense.

(ii) Notwithstanding Section 8.8(b)(i)(C) above, no such compromise or settlement of the Third Party Claim may be made without the written consent of the Indemnified Party, which consent will not be unreasonably withheld, conditioned or delayed. The Indemnified Party may withhold such consent if such compromise or settlement would materially and adversely affect the Acquired Companies or requires less than an unconditional release with respect to the Third Party Claim.

(iii) The Indemnifying Party will provide the indemnified party access to all records, documents and personnel of the Indemnifying Party and keep the indemnified party informed relating to any Third Party Claim under this Section 8.8.

(iv) The term “Conflict of Interest” means that the named parties to a Third Party Claim include both of the Indemnifying Party and the indemnified party and the indemnified party has been advised in writing by counsel that there exist one or more legal defenses available to the indemnified party that are different from or additional to those available to the Indemnifying Party, and which, if asserted, would create a conflict of interest with the Indemnifying Party.

(i) If the Indemnifying Party fails to assume the defense of such Third Party Claim within fifteen (15) days after receipt of notice thereof pursuant to this Section 8.8 or there is a Conflict of Interest, the indemnified party may (A) take control of the defense and investigation of the Third Party Claim, (B) employ and engage attorneys of its own choice to handle and defend the Third Party Claim at the indemnifying party’s cost, risk and expense, which attorneys must be reasonably satisfactory to the Indemnifying Party, and (C) subject to Section 8.8(c)(ii) below, compromise or settle the Third Party Claim.

(ii) Notwithstanding Section 8.8(c)(i)(C) above but also subject to Section 8.8(e), no such compromise or settlement of the Third Party Claim may be made without first seeking the written consent of the Indemnifying Party, which consent will not be unreasonably withheld, conditioned or delayed; provided, however, that if such consent is withheld, conditioned or delayed, then the Indemnified Party shall nonetheless be entitled to compromise or settle such Third Party Claim without prejudice to its rights to recover any Losses related to such Third Party Claim (including the compromise or settlement thereof) hereunder.

(iii) The indemnified party will provide the Indemnifying Party access to all records, documents and personnel of the indemnified party and keep the Indemnifying Party informed relating to any Third Party Claim under this Section 8.8.

(d) Liability, Costs and Expenses. The Indemnifying Party will be liable for any settlement of any action effected pursuant to and in accordance with this Section 8.8 and for any final judgment (subject to any right of appeal), and the Indemnifying Party agrees to indemnify and hold harmless the indemnified party from and against any damages by reason of such settlement or judgment. Regardless of whether the Indemnifying Party or the indemnified party takes up the defense, the Indemnifying Party will pay the costs and expenses in connection with the defense, compromise or settlement for any Third Party Claim under this Section 8.8.

8.9 Subrogation. With respect to any Third Party Claim for which the Indemnifying Party is obligated to indemnify the Indemnified Party, the Indemnifying Party shall be subrogated to all rights and claims of the Indemnified Party with respect to such Loss.

8.10 Exclusive Remedy. From and after the Closing Date, the indemnification obligations pursuant this Article VIII shall constitute the sole and exclusive remedies (other than a remedy for fraud) of Buyer (including the Indemnified Parties) or Seller, respectively, for the breach of any representation or warranty in this Agreement by Buyer, the Acquired Companies or Seller, as the case may be, and Buyer, the Acquired Companies and Seller shall not be entitled to rescission of this Agreement or to any further indemnification rights or claims of any nature whatsoever in respect thereof, whether such claims or rights are based on tort, contract or otherwise, all of which Buyer, the Acquired Companies and Seller waive and agree not to pursue.

9.2 Effect of Termination.

10.5 Rights Reservation.
