Likewise, the failure to include an Authorization on Schedule 2.9 shall not be interpreted to mean such Authorization is not intended to be transferred and, to cure the violation of Section 2.9 caused by failure to include such Authorization, Seller shall be required, at Purchaser’s option, and without precluding other remedies, to transfer such Authorization or to assist Purchaser to obtain a replacement Authorization in Purchaser’s name, in accordance with Sections 4.2(b) and 4.7 below.

(b) Except as set forth on Schedule 2.13(b), neither the execution, delivery and performance of this Agreement or the documents or instruments executed in connection herewith, nor consummation of the transactions contemplated hereby or thereby, will: (i) constitute a material breach of or default under any instrument, contract, license or agreement governing or affecting any IP Rights to which Seller is a party; (ii) except as set forth on Schedule 2.13(b) hereto, cause the forfeiture or termination of, or give rise to a right of forfeiture or termination of, any IP Right; or (iii) materially impair the right of Purchaser to use, possess, sell or license any IP Right or portion thereof. Except as set forth on Schedule 2.13(b) hereto or as set forth in the

11

Purchased Contracts, there are no royalties, honoraria, fees or other payments payable by Seller to any third person by reason of the ownership, use, possession, license, sale, marketing, advertising or disposition of any IP Rights.

(c) Neither the manufacture, marketing, license, sale, furnishing or intended use of any product or service currently licensed, utilized, sold, provided or furnished by the Business, or currently under development by the Business, violates any license or agreement between Seller and any third party or infringes or misappropriates any Intellectual Property right of any other party; and there is no basis for any claim contesting the validity, ownership or right of Seller to use, possess, sell, market, advertise, license or dispose of any IP Right in the manner currently so used by Seller, or in the manner previously used by Seller with respect to any previous versions of Products that are still being used by customers under Purchased Contracts, nor has Seller received any notice asserting that any IP Right or the proposed use, sale, license or disposition thereof conflicts or will conflict with the rights of any other party. This subsection 2.13(c) shall not apply to any IP Right licensed by Seller from a third party except to the extent Seller is aware of any violation, infringement or misappropriation of the Intellectual Property rights of a third party, or of facts reasonably likely to give rise to a claim of such violation, infringement or misappropriation or to a claim contesting the right of Seller to use such Intellectual Property.

To Seller’s knowledge, the employment of any employee of Seller or the use by Seller of the services of any consultant or independent contractor of Seller does not subject the Business to any liability to any third party related to misappropriation of trade secrets, violation of any noncompetition agreement, violation of any form of non-disclosure agreement, or the infringement of intellectual property rights.

(e) Except as set forth on Schedule 2.13(e) hereto or as set forth in the Purchased Contracts, there are no and will be no royalties, honoraria, fees or other payments (other than salaries payable to employees and amounts payable to independent contractors not contingent on or related to use of their work product) payable by the Seller before, or will be payable by the Purchaser after, the Closing Date, to any third person by reason of the ownership, use, possession, license, copying, modifying,

All officers, employees and consultants or third party developers of Seller, excluding lawyers, accountants and similar professionals, having access to proprietary information of the Business, its customers or business partners, have executed and delivered to Seller an agreement regarding the protection of such proprietary information and the assignment of inventions or work product to Seller; and copies of all such agreements have been delivered or made available to Purchaser’s counsel. Seller has secured written assignments from all consultants (including third-party developers), contractors and employees who were involved in, or who contributed to, the creation or development of any Intellectual Property owned by Seller, assigning the rights to such contributions that may be owned by such Persons or that Seller does not already own by operation of law. No current or former employee, officer, director, consultant or independent contractor of Seller has any right, license or ownership interest whatsoever, and Seller has not received notice of any claims, in or with respect to, any Intellectual Property owned by Seller.

ARTICLE 7

INDEMNIFICATION

7.1 Indemnification by Seller

(a) Subject to the provisions of Sections 7.1(b), 7.4 and 7.5 below, Seller shall indemnify Purchaser and its Affiliates, and each of their respective shareholders, officers, directors, employees and representatives (each a “Purchaser Indemnitee”) against, and hold each Purchaser Indemnitee harmless from, any and all claims, losses, damages, liabilities, payments and obligations, and all expenses, including without limitation reasonable legal fees (collectively “Losses”), incurred, suffered, sustained or required to be paid, directly or indirectly, by, or sought to be imposed upon, such Purchaser Indemnitee resulting from, related to or arising out of (i) any inaccuracy in or breach of any of the representations or warranties made by Seller in or pursuant to this Agreement or the agreements or documents delivered by Seller pursuant to Sections 5.1(b)(i), (iii), (iv), (v), (viii), and (ix); provided, however, that (ix) shall be limited to documents that are necessary to convey to Purchaser title to the Purchased Assets; (ii) any breach of any of the covenants made by Seller in or pursuant to this Agreement (including Section 5.1(b)(ii)) or the agreements or documents delivered by Seller pursuant to Section 5.1(b)(iii), (iv), (v), (viii) and (ix); provided, however, that (ix) shall be limited to documents that are necessary to convey to Purchaser title to the Purchased Assets; (iii) the Excluded Assets or Excluded Liabilities, including with respect to Taxes and bulk sales laws; and (iv) the conduct of the Business prior to the Closing Date. The lack of indemnity under this Section 7.1(a) for breaches shall not limit the remedies that may be available to Purchaser under the Noncompetition Agreement.

(b) Each Purchaser Indemnitee shall promptly give written notice to Seller of the assertion by any Person of any claim, action, suit or proceeding with respect to which Seller is obligated to provide indemnification hereunder; provided, however, that the rights of a Purchaser Indemnitee to be indemnified hereunder shall only be affected by the failure to give such notice if and to the extent such failure prejudices Seller in the defense of such third party claim. Amounts due with respect to Losses covered by this Section 7.1 shall be paid promptly after delivery of reasonably documented written notice of the amount of Losses incurred, and if Seller disputes the validity of the notice or the amounts of the Losses and such dispute is ultimately resolved wholly or partially in favor of the Purchaser Indemnitee, Seller shall promptly pay the amount found owing. Seller shall have the right, but not the obligation, to contest, defend or litigate, and to retain counsel of its choice in connection with, any claim, action, suit or proceeding by any third party alleged or asserted against a Purchaser Indemnitee that is subject to indemnification by Seller hereunder, and the cost and expense thereof shall be subject to the indemnification obligations and limitations of Seller hereunder; provided, that each Purchaser Indemnitee shall have the right and option to participate in, but not control, the defense of such action at its own expense and with its own counsel; and provided, further, that, (i) if Seller elects not to defend any such action or (ii) if a Purchaser Indemnitee shall reasonably believe that it has defenses not available to Seller

31

and if counsel to Purchaser shall advise in a written opinion that common representation is not appropriate, then such Purchaser Indemnitee shall be entitled, through counsel of its choice, but at Seller’s expense (should indemnification be applicable), to participate in the defense of such action. Neither Seller, on the one hand, nor any Purchaser Indemnitee, on the other hand, shall be entitled to settle or compromise any such claim, action, suit or proceeding without the prior written consent of the other party, which consent shall not be unreasonably withheld.

7.2 Indemnification by Purchaser.

(a) Subject to the provisions of Sections 7.2(b) and 7.4 below, Purchaser shall indemnify Seller and its Affiliates and each of their respective stockholders, officers, directors, employees and representatives (each a “Seller Indemnitee”) against, and hold each Seller Indemnitee harmless from, any and all Losses incurred, suffered, sustained or required to be paid, directly or indirectly, by, or sought to be imposed upon, such Seller Indemnitee resulting from, related to or arising out of (i) any inaccuracy in or breach of any of the representations, warranties or covenants made by Purchaser in or pursuant to this Agreement or in any agreement, document or instrument executed and delivered pursuant to Section 5.2(b)(iii) or (iv), (ii) the Assumed Liabilities and (iii) the conduct of the Business as conducted by Purchaser after the Closing Date, unless such Losses result from, relate to or arise out of any inaccuracy in or breach of any of the representations, warranties or covenants made by Seller in or pursuant to this Agreement or in any agreement, document or instrument executed and delivered pursuant hereto or in connection with the Closing of the transactions contemplated hereunder.

(b) Each Seller Indemnitee shall promptly give written notice to Purchaser of the assertion by any Person of any claim, action, suit or proceeding with respect to which Purchaser is obligated to provide indemnification hereunder; provided, however, that the rights of a Seller Indemnitee to be indemnified hereunder shall only be affected by the failure to give such notice if and to the extent such failure prejudices Purchaser in the defense of such third party claim. Amounts due with respect to Losses covered by this Section 7.2 shall be paid promptly after delivery of reasonably documented written notice of the amount of Losses incurred, and if Purchaser disputes the validity of the notice or the amounts of the Losses and such dispute is ultimately resolved wholly or partially in favor of the Seller Indemnitee, Purchaser shall promptly pay all amounts due. Purchaser shall have the right, but not the obligation, to contest, defend or litigate, and to retain counsel of its choice in connection with, any claim, action, suit or proceeding by any third party alleged or asserted against a Seller Indemnitee that is subject to indemnification by Purchaser hereunder, and the cost and expense thereof shall be subject to the indemnification obligations and limitations of Purchaser hereunder; provided, that each Seller Indemnitee shall have the right and option to participate in, but not control, the defense of such action at its own expense and with its own counsel; and provided, further, that (i) if Purchaser elects not to defend any such action or (ii) if a Seller Indemnitee shall reasonably believe that it has defenses not available to Purchaser and if counsel to Seller shall in a written opinion advise that

32

common representation is not appropriate, then such Seller Indemnitee shall be entitled, through counsel of its choice, but at Purchaser’s expense (should indemnification be applicable), to participate in the defense of such action. Neither any Seller Indemnitee nor Purchaser shall be entitled to settle or compromise any such claim, action, suit or proceeding without the prior written consent of the other party, which consent shall not be unreasonably withheld.

7.3 Indemnity for Taxes, Environmental Matters.

(a) Notwithstanding any limitations of or exceptions stated within Article 2 or in the other provisions of this Article 7, Seller shall indemnify Purchaser Indemnitees from and against any Losses for Taxes based upon or arising out of matters occurring prior to the Closing (even if disclosed). Purchaser shall indemnify Seller from and against all Tax liability related to the Business as conducted by Purchaser based upon or arising from matters following the Closing.

(b) Notwithstanding any limitations of or exceptions stated within Article 2 or in the other provisions of this Article 7, Seller shall indemnify Purchaser Indemnitees from and against any Losses arising under any Environmental Laws based upon or arising out of acts, omissions, events or conditions which occurred or existed prior to the Closing (even if disclosed). Purchaser shall indemnify Seller from and against all Losses arising under any Environmental Law based upon or arising out of acts, omissions, events or conditions relating to the Business as conducted by Purchaser which first occur following the Closing.

7.4 Survival of Representations, Warranties and Covenants; Reliance.

(a) All representations and warranties contained herein or made pursuant hereto shall survive the Closing hereunder until the date that is twenty four (24) months after the Closing Date, except that the representations and warranties in Section 2.16 (Environmental Laws) and 2.17 (Taxes) shall survive the Closing until the expiration of all applicable statutes of limitations. The expiration of any representation and warranty shall not affect any claim for indemnification made prior to the date of such expiration.

(b) The representations and warranties made by any party in this Agreement or in any agreement, certificate, schedule or exhibit delivered in connection with this Agreement may be fully and completely relied upon by each other party without regard to any investigation made by or on behalf of such other party.

(c) The covenants of the parties in Sections 4.1, 4.3, 4.4, 4.7, 4.9, 4.10, 4.17 and 4.18 shall survive the Closing.

33

7.5 Limitations on Indemnification.

(a) Except as set forth in Section 7.5(b), Seller’s indemnification obligations in Sections 7.1(a)(i) or (ii) shall not exceed an aggregate amount equal to the Purchase Price (the “Cap Amount”).

(b) Seller’s aggregate indemnification obligations under Sections 7.1(a)(i) and (ii), to the extent such obligations arise from a breach of any of the representations and warranties contained in Section 2.7(a) (Title), Section 2.13 (Intellectual Property) or Section 4.6 (Bulk Sales) shall not, when added to any amounts paid to satisfy indemnification obligations with respect to any other representations and warranties, exceed an aggregate amount equal to three (3) times the Cap Amount. In any event, the aggregate indemnification obligation of Seller under Sections 7.1(a)(i) and (ii) shall not exceed three (3) times the Cap Amount, and the limitation set forth in this Section 7.5(b) shall be inclusive of the limitation set forth in Section 7.5(a), and not in addition to such limitation.

(c) Notwithstanding the provisions of this Article 7, Seller shall not have any indemnification obligation under this Agreement for any (except Section 7.3) indemnification claims under Sections 7.1(a)(i) and (ii) unless and until the aggregate amount of the Losses of the Purchaser Indemnitee exceeds $25,000 in the aggregate, whereupon Seller shall be liable to indemnify the Purchaser Indemnitee only to the extent that such Losses exceed $25,000.

(d) The amount payable by a Seller Indemnitee or Purchaser Indemnitee with respect to a Loss shall be reduced by the amount of any insurance proceeds received by the Purchaser Indemnitee or Seller Indemnitee as applicable with respect to the Loss, and each of the Purchaser Indemnitees and Seller Indemnitees hereby agrees to use reasonable efforts to collect any and all insurance proceeds to which either may be entitled in respect of any Loss or to permit Seller or Purchaser to do so if permitted under the applicable insurance policy.

ARTICLE 8
