VII. Registration of the Shares. Piggyback Registration Rights. (i) If, at any time commencing after the date of this Subscription Agreement and expiring five (5) years thereafter, the Company proposes to file a registration statement or statements under the Securities Act for the public sale of the Common Stock for cash (other than in connection with a merger or pursuant to Form S-4, Form S-8 or comparable registration statement), it will give written notice, at least thirty (30) days prior to the filing of each such registration statement, to the undersigned of its intention to do so. If the undersigned notifies the Company in writing within ten (10) business days after receipt of any such notice of its desire to include the Shares in such proposed registration statement, the Company shall afford the undersigned the opportunity to have the Shares registered under such registration statement; provided, however, that in the case of an underwritten offering, if the Company notifies the undersigned in writing that the managing underwriter of such offering has notified the Company that the inclusion in the registration statement of any portion of the Shares would have an adverse effect on such underwritten offering, then the managing underwriter may limit the number of Shares to be included in such registration statement only to the extent necessary to avoid such adverse effect; provided, further, however, that in the event securities of the Company held by any person or entity other than the Company or the undersigned (the "Third Party Securities") are to be included in such underwritten offering, and the managing underwriter shall have determined to limit the number of shares of Common Stock or Third Party Securities to be so included, then such limitation shall be applied to the Shares and the Third Party Securities, based on the number of Shares and Third Party Securities requested to be included in such underwritten offering so that the amount of Third Party Securities are reduced by a percentage which is twice as great as the percentage which the Shares are -3- reduced. Notwithstanding the provisions of this Section VII(i), the Company shall have the right at any time after it shall have given written notice pursuant to this Section VII(i) (irrespective of whether a written request for inclusion of any such securities shall have been made) to elect not to file any such proposed registration statements or to withdraw the same after the filing but prior to the effective date thereof. (ii) Following the effective date of a registration statement filed pursuant to Section VII(i), the Company shall, upon the written request of the undersigned, forthwith supply such reasonable number of copies of the registration statement, prospectus and other documents necessary or incidental to the registration as shall be reasonably requested by the undersigned to permit the undersigned to make a public distribution of the Shares. The Company will use its reasonable efforts to qualify the Shares for sale in such states as the undersigned shall reasonably request, provided that no such qualification will be required in any jurisdiction where, solely as a result thereof, the Company would be subject to general service of process or to taxation or qualification as a foreign corporation doing business in such jurisdiction. The obligations of the Company hereunder with respect to the Shares are expressly conditioned on the undersigned furnishing to the Company such appropriate information concerning the undersigned and the Shares as the Company may reasonably request. (iii)The Company shall bear the entire cost and expense of the registration of the Shares pursuant to Section VII(i); provided, however, that the undersigned shall be solely responsible for the fees of any counsel retained by the undersigned in connection with such registration and any transfer taxes or underwriting discounts, commissions or fees applicable to the Shares sold by the undersigned pursuant thereto. (iv) Neither the filing of a registration statement by the Company pursuant to this Section VII nor the making of any request for prospectuses by the undersigned shall impose upon the undersigned any obligation to sell the Shares. (v) The undersigned, upon receipt of notice from the Company that an event has occurred which requires a post-effective amendment to a registration statement or a supplement to a prospectus included therein, shall promptly discontinue the sale of the Shares until the undersigned receives a copy of a supplemented or amended prospectus from the Company, which the Company shall provide as soon as practicable after such notice. (vi) Notwithstanding anything else to the contrary contained in this Subscription Agreement, if the undersigned requests to have any of the Shares registered under the Securities Act pursuant to this Section VII, and if such Shares are so registered, then this Section VII shall be of no further force or effect. VIII. Registration Indemnification. (a) The Company shall indemnify and hold harmless the undersigned from and against any and all losses, claims, damages and liabilities caused by any untrue statement of a material fact contained in any registration statement covering the Shares filed by the Company under the Securities Act, any post-effective amendment to such registration statement, or any prospectus included therein required to be filed or furnished by reason of Section VII of this Subscription Agreement or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except, insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission based upon information furnished or required to be furnished in writing to the Company by the undersigned expressly for use therein, which indemnification shall include each person, if any, who controls the undersigned within the -4- meaning of the Securities Act; provided, however, that the indemnification in this paragraph VIII(a) with respect to any prospectus shall not inure to the benefit of the undersigned (or to the benefit of any person controlling the undersigned) on account of any such loss, claim, damage or liability arising from the sale of the Shares by the undersigned, if a copy of a subsequent prospectus correcting the untrue statement or omission in such earlier prospectus was provided to the undersigned by the Company prior to the subject sale and the subsequent prospectus was not delivered or sent by the undersigned to the purchaser prior to such sale; and provided further, that the Company shall not be obligated to so indemnify the undersigned or other person referred to above unless the undersigned or other person, as the case may be, shall at the same time indemnify the Company, its directors, each officer signing such registration statement and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any and all losses, claims, damages and liabilities caused by any untrue statement of a material fact contained in such registration statement, any registration statement or any prospectus required to be filed or furnished by reason of this Subscription Agreement or caused by any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission based upon information furnished in writing to the Company by the undersigned expressly for use therein. (b) If for any reason the indemnification provided for in the preceding subparagraph is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect not only the relative benefits received by the indemnified party and the indemnifying party, but also the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations.
