(a) At any time when a Registration Statement effected pursuant to Paragraph 6.2 is effective, upon written notice from the Purchaser to the Selling Stockholders that the Purchaser has determined in good faith that the sale of Restricted Stock pursuant to the Registration Statement would require disclosure of non-public material information, the Selling Stockholders shall suspend sales of Restricted Stock pursuant to such Registration Statement until such time as the Purchaser notifies the Selling Stockholders that such material information has been disclosed to the public or has ceased to be material, or that sales pursuant to such Registration Statement may otherwise be resumed. (b) Notwithstanding any other provision of this Agreement, the Selling Stockholders shall not effect any public sale or distribution (including sales pursuant to Rule 144), if and when available, of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the thirty (30) days prior to the commencement of any primary offering to be undertaken by the Purchaser of shares of its unissued Common Stock ("Primary Offering"), which may also include other securities, and ending one hundred twenty (120) days after completion of any such Primary Offering, unless the Purchaser, in the case of a non-underwritten Primary Offering, or the managing underwriter, in the case of an underwritten Primary Offering, otherwise agree. 6.7. INDEMNIFICATION. (a) The Purchaser agrees to indemnify, to the extent permitted by law, each Selling Stockholder, such Selling Stockholder's respective partners, officers, directors, underwriters and each Person who controls any Selling Stockholder (within the meaning of the Act) against all losses, claims, damages, liabilities and expenses caused by (i) any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto, (ii) any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Purchaser of the Act, the Exchange Act, any state 14 securities law or any rule or regulation promulgated under the Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement ("Violations"); PROVIDED, HOWEVER, that the indemnity agreement contained in this Section 6.7(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Purchaser, which consent shall not be unreasonably withheld, nor shall the Purchaser be liable in for any loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Selling Stockholder, partner, officer, director, underwriter or controlling person of such Selling Stockholder. (b) To the extent permitted by law, each Selling Stockholder shall indemnify and hold harmless the Purchaser, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Act, any underwriter and any other Selling Stockholder selling securities under such registration statement or any of such other Selling Stockholder's partners, directors or officers or any person who controls such Selling Stockholder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Selling Stockholder, or partner, director, officer or controlling person of such other Selling Stockholder, may become subject under the Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation (i) occurs in reliance upon and in conformity with written information furnished by such Selling Stockholder under an instrument duly executed by such Selling Stockholder for use in connection with such registration; or (ii) occurs as a result of any disposition of the Restricted Stock in a manner that fails to comply with the permitted methods of distribution identified within the Registration Statement. (c) Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any Person's right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party), and (ii) unless in such indemnified party's reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. (d) If the indemnification provided for in this Section 6.7 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law 15 contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the violation(s) described in Section 6.7(a) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; PROVIDED, that in no event shall any contribution by a Selling Stockholder hereunder exceed the net proceeds from the offering received by such Selling Stockholder. (e) The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and shall survive the transfer of securities. The Purchaser also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Purchaser's indemnification is unavailable for any reason.
