If the Company proposes to register any shares of Common Stock or other securities issued by it having terms substantially similar to Eligible Securities ("Other Securities") for public sale under the Securities Act (whether proposed to be offered for sale by the Company or by any other Person) on a form and in a manner which would permit registration of Eligible Securities for sale to the public under the Securities Act, it will give prompt written notice to each Investor of its intention to do so, and upon the written request of any of the Investors delivered to the Company within fifteen (15) Business Days after the giving of any such notice (which request shall specify the number of Eligible Securities intended to be disposed of by such Investor and the intended method of disposition thereof) the Company will use all reasonable efforts to effect, in connection with the registration of the Other Securities, the registration under the Securities Act of all Eligible Securities which the Company has been so requested to register by the Investor or Investors, to the extent required to permit the disposition (in accordance with the intended method or methods thereof as aforesaid) of Eligible Securities so to be registered provided that: (a) if, at any time after giving such written notice of its intention to register any Other Securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register the Other Securities, the Company may, at its election, give 3 written notice of such determination to the Investor or Investors seeking registration hereunder (hereafter referred to as the "SELLING INVESTORS") and thereupon the Company shall be relieved of its obligation to register such Eligible Securities in connection with the registration of such Other Securities (but not from its obligation to pay Registration Expenses to the extent incurred in connection therewith as provided in Section 3.2); (b) The Company will not be required to effect any registration pursuant to this Article 3 if the Company shall have been advised in writing (with a copy to Investor) by a nationally recognized independent investment banking firm selected by the Company to act as lead underwriter in connection with the public offering of securities by the Company, that in such firm's opinion, a registration of the Eligible Securities which the Company has been requested to register by Investor at that time would materially and adversely affect the Company's own scheduled offering; and (c) The Company shall not be required to effect any registration of Eligible Securities under this Article 3 incidental to the registration of any of its securities in connection with mergers, acquisitions, exchange offers, subscription offers, dividend reinvestment plans or stock options or other employee benefit plans. 3.3 REGISTRATION EXPENSES. The Company (as between the Company and the Selling Investors) shall be responsible for the payment of all Registration Expenses in connection with any registration pursuant to this Article 3. 3.4 LOCK-UP AGREEMENT.

The Company may also impose such restrictions and limitations on the distribution of such Eligible Securities as the Company reasonably believes are necessary or advisable to comply with applicable law or to effect an orderly distribution, including those restrictions set forth in Section 4.3 hereof. 4.2 UNDERWRITING. (a) In the event that any registration pursuant to Article 3 hereof shall involve, in whole or in part, an underwritten offering, the Company may require Eligible Securities requested to be registered pursuant to Article 3 to be included in such underwriting on the same terms and conditions as shall be applicable to the Other Securities being sold through underwriters under such registration. (b) If requested by the underwriters for any underwritten offering of Eligible Securities pursuant to a registration requested hereunder, the Company will enter into and perform its obligations under an underwriting agreement with such underwriters for such offering, such agreement to contain such representations and warranties by the Company and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, indemnities and contribution to the effect and to the extent provided in Article 6 hereof. Each Selling Investor shall be a party to any such underwriting agreement and the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of each such Selling Investor. Such agreement shall also contain such representations and warranties by each such Selling Investor and such other terms and provisions as are customarily contained in underwriting agreements with respect to secondary distributions, including, without limitation, indemnities and contribution to the effect and to the extent provided in Article 6. 4.3 BLACKOUT PERIODS. At any time when a registration statement effected pursuant to Article 3 relating to Eligible Securities is effective, upon written notice from the Company to an Investor that the Company has determined in good faith, with the advice of counsel, that such Investor's sale of Eligible Securities pursuant to the registration statement would require disclosure of non-public material information the disclosure of which would have a material adverse effect on the Company or would otherwise adversely effect a material financing, acquisition, disposition, merger or other comparable transaction (a "Blackout"), such Investor shall suspend sales of Eligible Securities pursuant to such registration statement until the earlier of: (a) the date upon which such material information is disclosed to the public or ceases to be material, or (b) such time as the Company notifies such Investor that sales pursuant to such registration statement may be resumed. 4.4 QUALIFICATION FOR RULE 144 SALES. The Company will take all actions reasonably necessary to comply with the filing requirements described in Rule 144(c)(1) so as to 6 enable the Investors to sell Eligible Securities without registration under the Securities Act and, upon the written request of any Investor, the Company will deliver to such Investor a written statement as to whether it has complied with such filing requirements. ARTICLE V PREPARATION; REASONABLE INVESTIGATION 5.1 PREPARATION; REASONABLE INVESTIGATION. In connection with the preparation and filing of each registration statement registering Eligible Securities under the Securities Act, the Company will give each Selling Investor and the underwriters, if any, and their respective counsel and accountants, drafts of such registration statement for their review and comment prior to filing and such reasonable and customary access to its books and records and such opportunities to discuss the business of the Company with its officers and the independent public accountants who have certified its financial statements as shall be necessary, in the opinion of the Selling Investors and such underwriters or their respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act. ARTICLE VI INDEMNIFICATION AND CONTRIBUTION 6.1 INDEMNIFICATION AND CONTRIBUTION. (a) In the event of any registration of Eligible Securities hereunder, the Company will enter into customary indemnification arrangements to indemnify and hold harmless each Selling Investor, and each Person who participates as an underwriter in the offering or sale of such securities, and each Person, if any, who controls such underwriter within the meaning of the Securities Act against any losses, claims, damages, liabilities and expenses, joint or several, to which such Person may be subject under the Securities Act or otherwise insofar as such losses, claims, damages, liabilities or expenses (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus or final prospectus included therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or (ii) 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 the Company will promptly reimburse each such Person for any legal or any other expenses reasonably incurred by such Person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; PROVIDED that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus or final prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Selling Investor expressly for use in the registration statement.

Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the transfer of the registered securities by the Investor and the expiration of this Agreement. Each Investor also shall agree to provide provision for contribution as shall be reasonably requested by the Company or any underwriters in circumstances where such indemnity is held unenforceable. (c) Indemnification and contribution similar to that specified in the preceding subdivisions of this Article 6 (with appropriate modifications) shall be given by the Company and each Selling Investor with respect to any required registration or other qualification of Eligible Securities under any federal or state law or regulation of governmental authority other than the Securities Act.
