7.11.2 The parties hereto agree that the services to be rendered by Shareholder pursuant to this Section 7 and the rights and privileges granted to Purchaser pursuant to this Section 7 are of a special, unique, extraordinary and intellectual character, which gives them a peculiar value, the loss of which cannot be reasonably or adequately compensated in damages in any action at law, and that the breach by Shareholder of any of the terms of this Section 7 will cause Purchaser great and irreparable injury and damage.

(a) any breach by Seller or Shareholder of any of its or his covenants or agreements in this Agreement or in any Ancillary Agreement;

-73-

(d) any third party claim in connection with any RSDL Product manufactured or sold or services performed by Seller on or before the Closing Date, except those claims relating solely to a defect in any RSDL Product as a result of the manufacturing of such RSDL Product (as oppose to a defect in the design or specifications);

(e) any Liabilities of Seller other than the Assumed Obligations;

(f) any Liabilities relating to the Business to the extent based upon or resulting from actions or omissions occurring on or prior to the Closing Date other than the Assumed Obligations;

(g) (i) any and all Taxes imposed on Seller, or for which Seller is liable, (ii) all Taxes arising out of a breach of the representations and warranties or covenants contained in Section 4, (iii) any and all Liabilities which may be asserted as a result of Seller’s noncompliance with any bulk transfer or bulk sales Law and (iv) any costs or expenses with respect to Taxes indemnified hereunder;

(h) any Labor Claim; and

9.2 Set-Off. Purchaser shall be entitled to set off any amounts owing by Seller and/or Shareholder pursuant to this Agreement, against any amounts owed to Seller and/or Shareholder pursuant to this Agreement.

9.3 Indemnification by Purchaser. Purchaser hereby agrees to indemnify and to hold Seller and Shareholder harmless from, against and in respect of and shall on demand reimburse Seller and Shareholder for any and all Loss suffered or incurred by Seller or Shareholder by reason of (a) any inaccurate representation, breach of warranty or nonfulfillment of any covenant or agreement by Purchaser contained herein, in any Ancillary Agreement or in any certificate, document or instrument delivered to Seller pursuant hereto or thereto or in connection herewith or therewith, (b) the Assumed Obligations, (c) any Liabilities relating to the Business to the extent based upon or resulting from actions or omissions occurring on or after the Closing Date (including any actions taken under Section 2.2), other than any Liabilities arising as a result of the gross negligence or willful misconduct of Shareholder and/or Seller during the Consulting Term and (d) any third party claim in connection with any RSDL Product manufactured

-74-

by Purchaser on or prior to the Closing Date resulting solely from a defect in the manufacturing of such RSDL Product (as opposed to a defect in the design or specifications).

9.4 Method of Asserting Claims. All claims for indemnification under Section 9 shall be asserted and resolved as follows:

9.4.1 The party claiming indemnification (the “Indemnified Party”) in respect of, arising out of or involving a claim or demand made by a third party against the Indemnified Party (a “Third Party Claim”) shall deliver notice (a “Claim Notice”) to the other party (the “Indemnifying Party”) as soon as reasonably practicable after receipt by such Indemnified Party of written notice of the Third Party Claim; provided, however, that failure to give such Claim Notice shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually prejudiced as a result of such failure. The Indemnifying Party shall promptly mitigate any such prejudice to the extent possible.

9.4.2 If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if it acknowledges that as between it and the Indemnified Party, it is responsible for such Third Party Claim, the Indemnifying Party may choose to assume the defense thereof with counsel selected by the Indemnifying Party, which counsel must be reasonably satisfactory to the Indemnified Party. Should the Indemnifying Party so assume the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof, but shall continue to pay for any expenses of investigation and any Loss suffered. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party. If (i) the Indemnifying Party shall not assume the defense of a Third Party Claim with counsel satisfactory to the Indemnified Party within five days of any Claim Notice, or (ii) legal counsel for the Indemnified Party notifies the Indemnifying Party that there are or may be legal defenses available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party, which, if the Indemnified Party and the Indemnifying Party were to be represented by the same counsel, would constitute a conflict of interest for such counsel or prejudice prosecution of the defenses available to such Indemnified Party, or (iii) if the Indemnifying Party shall assume the defense of a Third Party Claim and fail to prosecute such defense with reasonable diligence, then in each such case the Indemnified Party, by notice to the Indemnifying Party, may employ its own counsel and control the defense of the Third Party Claim and the Indemnifying Party shall be liable for the reasonable fees, charges and disbursements of counsel

-75-

employed by the Indemnified Party and the Indemnified Party shall be promptly reimbursed for any such fees, charges and disbursements, as and when incurred. Whether the Indemnifying Party or the Indemnified Party controls the defense of any Third Party Claim, the parties shall cooperate in the defense thereof. Such cooperation shall include the retention and provision to the counsel of the controlling party of records and information that are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnifying Party shall have the right to settle, compromise or discharge a Third Party Claim (other than any such Third Party Claim in which criminal conduct is alleged) without the Indemnified Party’s consent if such settlement, compromise or discharge (i) constitutes a complete and unconditional discharge and release of the Indemnified Party, and (ii) provides for no relief other than the payment of monetary damages and such monetary damages are paid in full by the Indemnifying Party.

9.4.3 If any Indemnified Party should have a claim under Section 9 against any Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party shall deliver notice (an “Indemnity Notice”) with reasonable promptness to the Indemnifying Party. The failure by any Indemnified Party to give the Indemnity Notice shall not impair such party’s rights hereunder except to the extent that an Indemnifying Party demonstrates that it has been actually prejudiced thereby. The Indemnifying Party shall promptly mitigate any such prejudice to the extent practicable. If the Indemnifying Party notifies the Indemnified Party that it does not dispute the claim described in such Indemnity Notice, the Loss in the amount specified in the Indemnity Notice will be conclusively deemed a liability of the Indemnifying Party under Section 9 and the Indemnifying Party shall pay such amount to the Indemnified Party on demand. If the Indemnifying Party disputes its liability with respect to such claim, the Indemnifying Party and the Indemnified Party will in good faith attempt to negotiate a resolution of such dispute.

Any party from time to time may change its address, facsimile number or other information for the purpose of notices to that party by giving notice specifying such change to the other party hereto.

12.2 Entire Agreement.

12.8 No Third Party Beneficiary. The terms and provisions of this Agreement are intended solely for the benefit of each party hereto and their respective successors or permitted assigns, and it is not the intention of the parties to confer third-party beneficiary rights, and this Agreement does not confer any such rights, upon any other Person other than any Person entitled to indemnity under Section 9.

12.9 Assignment; Binding Effect. Neither this Agreement nor any right, interest or obligation hereunder may be assigned (by operation of law or otherwise) by Seller without the prior written consent of Purchaser and any attempt to do so will be void.

-80-

         If Purchaser is assigning this Agreement to a Person owning assets having a fair market value at such time at more than $25 million, then Purchaser may assign this Agreement upon written notice to the Seller, provided that Purchaser’s assignee assumes (in writing) the then-outstanding obligations owing hereunder to Seller. Seller hereby consents to any such assignment that includes such an assumption, and acknowledges and agrees that such an assumption shall be deemed to effect a novation and a release of Purchaser with respect to the obligations so assumed by Purchaser’s assignee.

         If Purchaser is assigning this Agreement to a Person owning assets having a fair market value at such time at $25 million or less (a “Covered Assignee”), then Purchaser may assign this Agreement to such Covered Assignee upon written notice to the Seller, provided that the Covered Assignee assumes (in writing) Purchaser’s then-outstanding obligations owing hereunder to Seller. In addition, effective concurrently with such assignment to and assumption by the Covered Assignee, if any, Purchaser hereby guaranties, as a surety and on a contingent basis (i.e., Seller shall first exhaust his remedies against such assignee), the Covered Assignee’s payment of the assumed obligations in favor of Seller. Seller hereby consents to any such assignment that includes such an assumption and guaranty, and acknowledges and agrees that thereafter, Purchaser’s sole remaining obligation under this Agreement shall be pursuant to the guaranty contained in the preceding sentence.

12.12 Governing Law. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the

-81-

State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.

12.13 Construction. The parties hereto agree that this Agreement is the product of negotiation between sophisticated parties and individuals, all of whom were represented by counsel, and each of whom had an opportunity to participate in and did participate in, the drafting of each provision hereof.
