(b) Seller shall indemnify Buyer and each of Buyer’s officers, employees, agents, directors, legal counsel, and accountants, and each controlling Person of each of the foregoing (within the meaning of the Securities Act) against any Losses, to which any of them may be subject under the Securities Act or any other statute or at common law, insofar as such Losses arise out of or are based upon any untrue statement (or alleged untrue statement) of any material fact contained in any registration statement under which the Buyer Issued Stock were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or in any amendment or supplement thereto or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in such registration statement, preliminary prospectus, or amendment or supplement thereto solely in reliance upon and in conformity with written information furnished to Buyer by Seller specifically for use therein, and to reimburse such Persons for any legal or other expenses reasonably incurred in connection with investigating or defending any such Loss, as and when such expenses are incurred.

(c) If (i) an indemnified party makes a claim for indemnification pursuant to this Section 6.04 (subject to the limitations hereof) but it is found in a final judicial determination, not subject to further appeal, that such indemnification may not be enforced in such case or (ii) an indemnified party seeks contribution under the Securities Act, the Exchange Act, or otherwise, then Buyer (including for this purpose any contribution made by or on behalf of any director of Buyer, any officer of Buyer who signed the registration statement, and any controlling Person of Buyer) as one entity and the holders of Buyer Issued Stock, in the aggregate (including for this purpose any contribution by or on behalf of a Person who would be indemnified by Buyer) as a second entity, shall contribute to the Losses whatsoever to which any of them may be subject, so that the holders of Buyer Issued Stock and Buyer are each responsible for the proportion thereof which reflects as nearly as possible the relative fault of Buyer and the holders of Buyer Issued Stock in the aggregate in connection with the facts which resulted in such Losses. The relative fault, in the case of an untrue statement, alleged untrue statement, omission, or alleged omission, shall be determined by, among other things, whether such statement, alleged statement, omission, or alleged omission relates to information supplied, by Buyer or by the holders of Buyer Issued Stock, and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement, alleged statement, omission, or alleged omission. No Person guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. For purposes of this Section 6.04, each holder of Buyer Issued Stock and each of such holder’s officers, directors, employees, agents, partners, and legal counsel and accountants, and each controlling Person of each of the foregoing (within the meaning of the Securities Act or the Exchange Act) shall have the same rights to contribution as a holder of Buyer Issued Stock, and Buyer and each of its officers, employees, agents, directors, legal counsel and accountants, and each controlling Person of each of the foregoing (within the meaning of the Securities Act or the Exchange Act) shall have the same rights to contribution as Buyer, subject in each case to the provisions of this Section 6.04. Anything in this Section 6.04 to the contrary notwithstanding, no party shall be liable for contribution with respect to the settlement of any claim or action effected without its written consent. This Section 6.04 is intended to supersede any right to contribution under the Securities Act, the Exchange Act, or otherwise.

(d) Each party entitled to indemnification under this Section 6.04 (the “ Indemnified Party ”) shall give notice to the party required to provide indemnification (the “ Indemnifying Party ”) promptly after such Indemnified Party has knowledge of the commencement of any action, proceeding, or investigation in respect of which indemnity or reimbursement may be sought as provided above; provided , however , that the failure of such Indemnified Party to notify the Indemnifying Party with respect to a particular action, proceeding, or investigation shall not relieve the Indemnifying Party from any obligation or liability (i) which it may have pursuant to this Agreement if the Indemnifying Party is not substantially prejudiced by the failure to notify or (ii) which it may have otherwise than pursuant to this Agreement. The Indemnifying Party shall promptly assume the defense of any Indemnified Party with counsel reasonably satisfactory to such Indemnified Party, and the fees and expenses of such counsel shall be at the sole cost and expense of the Indemnifying Party. The Indemnified Party will cooperate with the Indemnifying Party in the defense of any action, proceeding, or investigation for which the Indemnifying Party assumes the defense. Notwithstanding the foregoing, any such Indemnified Party shall have the right to employ separate counsel of its own selection in any such action, proceeding, or investigation and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (x) the Indemnifying Party has agreed to pay such fees and expenses, (y) the Indemnifying Party shall have failed promptly to assume the defense of such action, proceeding, or investigation and employ counsel reasonably satisfactory to such Indemnified Party, or (z) in the reasonable judgment of such Indemnified Party there may be one or more defenses available to such Indemnified Party which are not available to the Indemnifying Party in respect of such action, proceeding, or investigation, in which case the Indemnifying Party shall not - have the right to assume the defense of such action, proceeding, or investigation on behalf of such Indemnified Party. An Indemnifying Party who is not entitled to, or elects not to, assume the defense of an action, proceeding, or investigation shall not be obligated to pay the fees and expenses of more than one counsel and appropriate local counsel for all parties indemnified by such Indemnifying Party pursuant to this Section 6.04 with respect to the same action, proceeding, or investigation, unless in the reasonable judgment of any such Indemnified Party a conflict of interest may exist between such Indemnified Party and any other such Indemnified Party with respect to such action, claim, or proceeding. The Indemnifying Party shall not be liable for the settlement by any Indemnified Party of any action, proceeding, or investigation effected without its consent, which consent shall not be unreasonably withheld. The Indemnifying Party shall not enter into any settlement in any action, suit, or proceeding to which an Indemnified Party is party unless such settlement includes a general release of the Indemnified Party, with no payment by the Indemnified Party of consideration.
