Upon the written request of a record holder of any Warrants or Warrant Shares given within 30 days after receipt of any such notice from the Company, the Company will, except as herein provided, cause all Warrant Shares, the record holders of which have so requested registration thereof, to be included in such registration statement, all to the extent requisite to permit the sale or other disposition by the prospective seller or sellers of the Warrant Shares to be so registered; provided, however, that nothing herein shall prevent the Company from, at any time, abandoning or delaying any registration; provided further, however, that if the Company determines not to proceed with a registration after the registration statement has been filed with the Commission and the Company's decision not to proceed is primarily based upon the anticipated public offering price of the securities to be sold by the Company, the Company shall promptly complete the registration for the benefit of those selling security holders who wish to proceed with a public offering of their securities and who bear all expenses incurred by the Company as the result of such registration after the Company has decided not to proceed. If any registration pursuant to this Section shall be underwritten in whole or in part, the Company may require that the Warrant Shares requested for inclusion pursuant to this Section be included in the underwriting on the same terms and conditions as the securities otherwise being sold through the underwriters. If in the good faith judgment of the managing underwriter of such public offering the inclusion of all of the Warrant Shares originally covered by a request for registration would reduce the number of shares to be offered by the Company or interfere with the successful marketing of the shares of stock offered by the Company, the number of Warrant Shares to be included in the underwritten public offering may be reduced pro rata among the holders thereof requesting inclusion in such registration. Those Warrant Shares which are thus excluded from the underwritten public offering shall be withheld from the market by the holders 13 thereof for a period, not to exceed 180 days, which the managing underwriter reasonably determines is necessary in order to effect the underwritten public offering, provided that the executive officers and directors of the Company shall have agreed to be bound by substantially the same terms and conditions and the restriction shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 (or similar forms promulgated after the date hereof) or a registration relating solely to a transaction pursuant Rule 145 promulgated under the Securities Act on Form S-14 or Form S- 15 (or similar forms promulgated after the date hereof). 8.2. Registration Procedures. If and whenever the Company is required to ----------------------- effect the registration of Warrant Shares under the Securities Act, the Company will: (a) prepare and file with the Commission a registration statement with respect to such securities, and use its best efforts to cause such registration statement to become and remain effective for such period as may be reasonably necessary to effect the sale of such securities, not to exceed six months; (b) prepare and file with the Commission such amendments to such registration statement and supplements to the prospectus contained therein as may be necessary to keep such registration statement effective for such period as may be reasonably necessary to effect the sale of such securities, not to exceed three months; (c) furnish to the security holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as such underwriters may reasonably request in order to facilitate the public offering of such securities; (d) use its best efforts to register or qualify the securities covered by such registration statement under such state securities or blue sky laws of such jurisdictions as such participating holders may reasonably request within 20 days following the original filing of such registration statement, except that the Company shall not for any purpose be required to execute a general consent to service of process or to qualify to do business as a foreign corporation in any jurisdiction wherein it is not so qualified; (e) notify the security holders participating in such registration, promptly after it shall receive notice thereof, of the time when such registration statement has become effective or a supplement to any prospectus forming a part of such registration statement has been filed; (f) notify such holders promptly of any request by the Commission for the amending or supplementing of such registration statement or prospectus or for additional information; (g) prepare and file with the Commission, promptly upon the request of any such holders, any amendments or supplements to such registration statement or 14 prospectus which, in the opinion of counsel for such holders (and concurred in by counsel for the Company), is required under the Securities Act or the rules and regulations thereunder in connection with the distribution of the Warrant Shares by such holder; (h) prepare and promptly file with the Commission and promptly notify such holders of the filing of such amendment or supplement to such registration statement or prospectus as may be necessary to correct any statements or omissions if, at the time when a prospectus relating to such securities is required to be delivered under the Securities Act, any event shall have occurred as the result of which any such prospectus or any other prospectus as then in effect would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading; (i) advise such holders, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such registration statement or the initiation or threatening of any proceeding for that purpose and promptly use its best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued; and (j) not file any amendment or supplement to such registration statement or prospectus to which a majority in interest of such holders shall have reasonably objected on the grounds that such amendment or supplement does not comply in all material respects with the requirements of the Securities Act or the rules and regulations thereunder, after having been furnished with a copy thereof at least two business days prior to the filing thereof, unless in the opinion of counsel for the Company the filing of such amendment or supplement is reasonably necessary to protect the Company form any liabilities under any applicable federal or state law and such filing will not violate applicable law. 8.3. Expenses. With respect to each inclusion of Warrant Shares in a -------- registration statement pursuant to Section 8.1, the Company shall bear the following fees, costs and expenses: all registration, filing and NASD fees, printing expenses, fees and disbursements of counsel and accountants for the Company and all legal fees and disbursements and other expenses of complying with state securities or blue sky laws of any jurisdictions in which the securities to be offered are to be registered or qualified. Fees and disbursements of counsel and accountants for the selling security holders, underwriting discounts and commissions and transfer taxes for selling security holders and any other expenses incurred by the selling security holders not expressly included above shall be borne by the selling security holders. 8.4. Indemnification. --------------- (a) The Company will indemnify and hold harmless each holder of Warrant Shares which are included in a registration statement pursuant to the provisions of this 15 Section and any underwriter (as defined in the Securities Act) for such holder and each person, if any, who controls such holder or such underwriter within the meaning of the Securities Act, from and against any and all loss, damage, liability, cost and expense to which such holder or any such underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, 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, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, damage, liability, cost or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such holder, such underwriter or such controlling person in writing specifically for use in the preparation thereof. (b) Each holder of Warrant Shares which are included in a registration pursuant to the provisions of this Section severally will indemnity and hold harmless the Company, any controlling person and any underwriter from and against any and all loss, damage, liability, cost or expense to which the Company or any controlling person and/or any underwriter may become subject under the Securities Act or otherwise, insofar as such losses, damages, liabilities, costs or expenses are caused by any untrue or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was so made in reliance upon and in strict conformity with written information furnished by such holder specifically for use in the preparation thereof and only to the extent of proceeds from the sale of Warrant Shares. (c) Promptly after receipt by an indemnified party pursuant to the provisions of paragraph (a) or (b) of this Section of notice of the commencement of any action involving the subject matter of the foregoing indemnity provisions, such indemnified party will, if a claim thereof is to be made against the indemnifying party pursuant to the provisions of said paragraph (a) or (b), promptly notify the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than hereunder. In case such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to participate in, and, to the extent that it may wish, jointly with any other indemnifying party 16 similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, if the defendants in any action include both the indemnified party and the indemnifying party and there is a conflict of interest which would prevent counsel for the indemnifying party from also representing the indemnified party, the indemnified party or parties shall have the right to select separate counsel to participate in the defense of such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party pursuant to the provisions of said paragraph (a) or (b) for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation, unless (i) the indemnified party shall have employed counsel in accordance with the proviso of the preceding sentence, (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after the notice of the commencement of the action, or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party. 9.
