In the even that an Investor fails to comply in any material respect with its obligations pursuant to Sections 5(d) through (i), all of such Investor's rights pursuant to this Agreement shall terminate other than with respect to Registrable Shares then registered on a Registration Statement. Section 6. INDEMNIFICATION. (a) ASII shall indemnify and hold harmless each of the Investors against any losses, claims, damages or liabilities, joint or several, to which such Investor may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment 5 or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by ASII of any rule or regulation promulgated under the Securities Act or any state securities law applicable to ASII and relating to action or inaction required of ASII in connection with any such registration, and will reimburse each such Investor for any reasonable legal and any other expenses incurred in connection with investigating, defending or settling any such claim, loss, damage, liability or action; PROVIDED, HOWEVER, that ASII will not be liable in any such case to the extent that any such claim, loss, damage or liability arises out of or is based on (i) the failure of any Investor to comply in any material respect with its obligations pursuant to Sections 5(d) through (i), or (ii) any untrue statement or omission based upon information furnished to or requested by ASII by or from any Investor for use therein. (b) Each Investor will, if Registrable Securities held by or issuable to such Investor are included in the securities as to which such registration is being effected, indemnify and hold harmless ASII, each of its directors and officers, each person who controls ASII, and each other Investor, against all claims, losses, expenses, damages and liabilities (or actions in respect thereof) arising out of or based on (i) the failure of any Investor to comply in any material respect with its obligations pursuant to Sections 5(d) through (i), or (ii) any untrue statement (or alleged statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document 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, and will reimburse ASII, each person who controls ASII, such directors or officers, or such other Investors for any reasonable legal or any other expenses incurred in connection with investigating, defending or settling any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with information furnished to or requested by ASII by or from such Investor specifically for use therein; PROVIDED, HOWEVER, the total amount for which any Investor shall be liable under this Section 6(b) shall not in any event exceed the aggregate proceeds received by such Investor from the sale of Registrable Securities sold by such Investor in such registration. (c) Each party entitled to indemnification under this Section 6 (the "INDEMNIFIED PARTY") shall give notice to the party required to provide indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party has actual knowledge of any claims as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations hereunder, unless such failure resulted in actual detriment to the Indemnifying Party. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the 6 consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a full and unconditional release from all liability in respect of such claim or litigation. (d) If the indemnification provided for in this Section 6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense 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 hand in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relevant fault of the Indemnifying Party and the Indemnified Party shall be determined 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. Notwithstanding the foregoing, the amount any Investor shall be obligated to contribute pursuant to this Section 6(d) shall be limited to an amount equal to the proceeds to such Investor of the Registrable Securities sold pursuant to the registration statement which gives rise to such obligation to contribute (less the aggregate amount of any damages which the Investor has otherwise been required to pay in respect of such loss, claim, damage, liability or action or any substantially similar loss, claim, damage, liability or action arising from the sale of such Registrable Securities). (e) The indemnification provided by this Section 6 shall be a continuing right to indemnification and shall survive the registration and sale of any securities by any person entitled to indemnification hereunder and the expiration or termination of this Agreement. Section 7. CERTIFICATE LEGENDS. Within five (5) business days after a registration statement filed under Section 2 hereof becomes effective, ASII will notify each Investor. Upon receipt of such notice, each Investor may return its certificate representing the Registrable Securities and request that ASII issue a new certificate in such Investor's name free of any restrictive legend relating to compliance with federal securities laws and ASII shall take all reasonable steps to do so; PROVIDED, HOWEVER, that ASII shall only be obligated to remove the legend for that number of Registrable Securities which any Investor represents is being sold pursuant to the registration statement. Section 8. TERMINATION OF RIGHTS. All rights of the Investors to demand registration of the Registrable Securities under this Agreement shall exist during the period (the "Demand Period") commencing on the date hereof and terminating at 5:00 P.M.
