SECTION 9.02.  Indemnification by the Company.  From and after the Closing, the Company shall indemnify Parent and its Affiliates and each of their respective officers, directors, employees, agents and representatives against and hold them harmless from any Losses suffered or incurred by any such indemnified party to the extent arising from: (i) any breach of any representation or warranty of the Company which survives the Closing contained in this Agreement; (ii) any breach of any covenant of the Company contained in this Agreement requiring performance after the Closing

(a)Notwithstanding any provision herein, neither Parent nor the Company shall in any event be liable to the other party or its Affiliates, officers, directors, employees, agents or representatives on account of any indemnity obligation set forth in Section 9.01 or Section 9.02 for any indirect, consequential, special, incidental or punitive damages (including lost profits, loss of use, damage to goodwill or loss of business).

(b)The Company and Parent shall cooperate with each other with respect to resolving any claim or liability with respect to which one party is obligated to indemnify the other party hereunder including by making commercially reasonable efforts to mitigate or resolve any such claim or liability.

(c)The Company acknowledges and agrees that: (i) other than the representations and warranties of Parent specifically contained in this Agreement, there are no representations or warranties of Parent, or any other person either expressed or implied with respect to the Transaction, the Product, the Acquired Assets or the Assumed Liabilities; and (ii) it shall have no claim or right to indemnification pursuant to Section 9.01 with respect to any information, documents or materials (other than this Agreement and the Parent Disclosure Schedule) furnished by Parent or any of its officers, directors, employees, agents or advisors to the Company and its representatives.

(d)The Company further acknowledges and agrees that, should the Closing occur, its sole and exclusive remedy with respect to any and all claims relating to this Agreement, any Other Transaction Document, the Transaction, any document or certificate delivered in connection herewith, the Product, the Acquired Assets and the Assumed Liabilities or any federal, state, local or foreign statute, law, ordinance, rule or regulation or otherwise (other than claims of, or causes of action arising from, fraud) shall be pursuant to the indemnification provisions set forth in this Article IX.  In furtherance of the foregoing, the Company hereby waives, from and after the Closing, to the fullest extent permitted under Applicable Law, any and all rights, claims and causes of action (other than claims of, or causes of action arising from, fraud) it or any of its Affiliates may have against Parent arising under or based upon this Agreement, any Other Transaction Document, the Transaction, any document or certificate delivered in connection herewith, the Product, the Acquired Assets and the Assumed Liabilities or any federal, state, local or foreign statute, law, ordinance, rule or regulation or otherwise (except pursuant to the indemnification provisions set forth in this Article IX).

SECTION 9.04.  Losses Net of Insurance, etc.  The amount of any Losses for which indemnification is provided under this Article IX shall be net of any amounts recovered or recoverable by the indemnified party under insurance policies with respect to such Losses and shall be reduced to take account of any net Tax benefit (including as a result of any basis adjustment) actually realized by the indemnified party arising from the incurrence or payment of any such Loss.  In computing the amount of any such Tax benefit, the indemnified party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the incurrence or payment of any indemnified Losses.

SECTION 9.05.  Termination of Indemnification.

(a)The obligations to indemnify and hold harmless a party hereto pursuant to: (i) Sections 9.0l(i) and 9.02(i) shall terminate when the applicable representation or warranty terminates

pursuant to paragraph (b) below; and (ii) the other clauses of Sections 9.01 and 9.02 shall not terminate; provided, however, that as to clause (i) of this sentence such obligations to indemnify and hold harmless shall not terminate with respect to any item as to which the person to be indemnified or the related party thereto shall have, before the expiration of the applicable period, previously made a claim by delivering a notice of such claim (stating in reasonable detail the basis of such claim) to the indemnifying party.

(b)The representations and warranties in this Agreement shall survive the Closing solely for purposes of Sections 9.01 and 9.02 and shall terminate at the close of business on August 17, 2013.

SECTION 9.06.  Procedures Relating to Indemnification for Third Party Claims.

(a)In order for a party to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any person against the indemnified party (a “Third Party Claim”), such indemnified party must notify the indemnifying party in writing, and in reasonable detail, of the Third Party Claim within ten (10) business days after receipt by such indemnified party of written notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnifying party shall have been prejudiced as a result of such failure (except that the indemnifying party shall not be liable for any expenses incurred during the period in which the indemnified party failed to give such notice).  Thereafter, the indemnified party shall deliver to the indemnifying party, promptly after the indemnified party’s receipt thereof, copies of all notices and documents (including court papers) received by the indemnified party relating to the Third Party Claim.

(b)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 so chooses, to assume the defense thereof with counsel selected by the indemnifying party; provided, however, that such counsel is not reasonably objected to by the indemnified party.  Should the indemnifying party so elect to 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.  If the indemnifying party assumes such defense, the indemnified party shall have the right to participate in the defense thereof and to employ counsel (not reasonably objected to by the indemnifying party), at its own expense, separate from the counsel employed by the indemnifying party, it being understood that the indemnifying party shall control such defense.  The indemnifying party shall be liable for the fees and expenses of counsel employed by the indemnified party for any period during which the indemnifying party has failed to assume the defense thereof (other than during the period prior to the time the indemnified party shall have given notice of the Third Party Claim as provided above).

(c)If the indemnifying party so elects to assume the defense of any Third Party Claim, all of the indemnified parties shall cooperate with the indemnifying party in the defense or prosecution thereof.  Such cooperation shall include the retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records and information which 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.  Whether or not the indemnifying party shall have assumed the defense of a Third Party Claim, the indemnified party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the indemnifying party’s prior written consent (which consent shall not be unreasonably withheld).

SECTION 9.07.  Procedures Related to Indemnification for Other Claims.  In the event any indemnified party should have a claim against any indemnifying party under Section 9.01 or 9.02 that does not involve a Third Party Claim being asserted against or sought to be collected from such

20

indemnified party, the indemnified party shall deliver notice of such claim with reasonable promptness to the indemnifying party.  The failure by any indemnified party to so notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to such indemnified party under Section 9.01 or 9.02, except to the extent that the indemnifying party demonstrates that it has been materially prejudiced by such failure.  If the indemnifying party disputes its liability with respect to such claim, the indemnifying party and the indemnified party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction.

SECTION 10.03.  Consequences of Termination.  In the event of the termination of this Agreement by Parent or the Company pursuant to this Article X, written notice thereof shall forthwith be given to the other party and this Agreement shall be terminated, without further action by either party.  If this Agreement is terminated as described in this Article X, this Agreement shall become void and of no further force or effect, except for the provisions of: (i) Section 8.03 relating to publicity; (ii) this Article X; (iii) Section 11.03 relating to certain expenses; (iv) Section 11.04 relating to attorney fees and expenses; and  (v) Section 11.10 relating to finder’s fees and broker’s fees.
