INDEMNIFICATION

7.1 Indemnification. Except as otherwise provided in this Article VII, the Company (the “Indemnifying Party”) agrees to indemnify, defend and hold harmless each of the Purchasers and its Affiliates and their respective officers, directors, agents, employees, subsidiaries, partners, members and controlling persons (each, an “Indemnified Party”) to the fullest extent permitted by law from and against any and all losses, Claims, or written threats thereof (including, without limitation, any Claim by a third party), damages, expenses (including reasonable fees, disbursements and other charges of counsel incurred by the Indemnified Party in any action between the Indemnifying Party and the Indemnified Party or between the Indemnified Party and any third party or otherwise) or other liabilities (collectively, “Losses”) resulting from or arising out of any breach of any representation or warranty, covenant or agreement by the

Company in this Agreement or the other Transaction Documents. The amount of any payment to any Indemnified Party herewith in respect of any Loss shall be of sufficient amount to make such Indemnified Party whole for any diminution in value of the Purchased Shares or the Beacon Warrant to the extent such diminution in value is attributable to such breach. In connection with the obligation of the Indemnifying Party to indemnify for expenses as set forth above, the Indemnifying Party shall, upon presentation of appropriate invoices containing reasonable detail, reimburse each Indemnified Party for all such expenses (including reasonable fees, disbursements and other charges of counsel incurred by the Indemnified Party in any action between the Indemnifying Party and the Indemnified Party or between the Indemnified Party and any third party) as they are incurred by such Indemnified Party; provided, however, that if an Indemnified Party is reimbursed under this Article VII for any expenses, such reimbursement of expenses shall be refunded to the extent it is finally judicially determined that the Losses in question resulted primarily from the willful misconduct or gross negligence of such Indemnified Party.

Indemnified Party is a party thereto or has been actually threatened to be made a party thereto) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Party from all liability arising or that may arise out of such Claim. The Indemnifying Party shall not be liable for any settlement of any Claim effected against an Indemnified Party without its written consent. The rights accorded to an Indemnified Party hereunder shall be in addition to any rights that any Indemnified Party may have at common law, by separate agreement or otherwise; provided, however, that notwithstanding the foregoing or anything to the contrary contained in this Agreement, nothing in this Article VII shall restrict or limit any rights that any Indemnified Party may have to seek equitable relief.

7.3 Contribution. If the indemnification provided for in this Article VII from the Indemnifying Party is unavailable to an Indemnified Party hereunder in respect of any Losses referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such Losses, as well as any other relevant equitable considerations. The relative faults of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses referred to above shall be deemed to include, subject to the limitations set forth in Sections 7.1 and 7.2, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding.
