The holders of Registrable Shares then holding 75% of the Registrable Shares requested to be included in such registration shall select one or more nationally recognized firms of investment bankers reasonably acceptable to the Company to act as the lead managing underwriter or underwriters in connection with such offering. (e) At any time before the registration statement covering Registrable Shares becomes effective, the holders of 75% of such shares may request the Corporation to withdraw or not to file the registration statement. In that event, if such request of withdrawal shall not have been caused by, or made in response to, the material adverse effect of an event on the business, properties, condition, financial or otherwise, or operations of the Corporation, the holders shall have used one of their demand registration rights under this Section 2 and the Corporation shall no longer be obligated to register Registrable Shares pursuant to the exercise of such one registration right pursuant to this Section 2 unless the remaining holders shall pay to the Corporation the expenses incurred by the Corporation through the date of such request. SECTION 3. PIGGYBACK REGISTRATION.

Without in any way limiting the number of registrations in which the Corporation shall be required to include Registrable Securities at the request of the required number of Investors pursuant to this Section 3 and Section 4 below, the Corporation shall only be responsible for the costs and expenses (including all expenses under Section 7 below) of up to four piggyback registrations pursuant to this Section 3 and up to four S-3 registrations pursuant to Section 4 below. SECTION 4. REGISTRATIONS ON FORM S-3. Anything contained in Section 2 to the contrary notwithstanding and subject to the last sentence of Section 3, at such time as the Corporation shall have qualified for the use of Form S-3 promulgated under the Securities Act or any successor form thereto, the holders of the Registrable Shares then outstanding shall have the right to request in writing an unlimited number of registrations of Registrable Shares on Form S-3 or such successor form of Registrable Shares, which request or requests shall (a) specify the number of Registrable Shares intended to be sold or disposed of and the holders thereof, (b) state the intended method of disposition of such Registrable Shares and (c) relate to Registrable Shares having an aggregate offering price of at least $250,000. A requested registration on Form S-3 or any such successor form in compliance with this Section 4 shall not count as a registration statement initiated pursuant to Section 2 but shall otherwise be treated as a registration initiated pursuant to, and shall, except as otherwise expressly provided in this Section 4, be subject to Section 2, including, without limitation, Section 2(a). SECTION 5. HOLDBACK AGREEMENT. If the Corporation at any time shall register shares of Common Stock under the Securities Act (including any registration pursuant to Sections 2, 3 or 4 hereof) for sale to the public, the Investors shall not sell publicly, make any short sale of, grant any option for the purchase of, or otherwise dispose publicly of, any Registrable Shares (other than those shares of Common Stock included in such registration pursuant to Sections 2, 3 or 4 hereof) without the prior written consent of the Corporation, for a period designated by the Corporation in writing to the Investors, which period shall begin not more than 10 days prior to the effectiveness of the registration statement pursuant to which such public offering shall be made and shall not last more than 90 days after the effective date of such registration statement.

(c) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for at least a period of 90 days or until all of such Registrable Shares have been disposed of (if earlier) and to comply with the provisions of the Securities Act with respect to the sale or other disposition of such Registrable Shares;

(i) subject to the execution of confidentiality agreements in form and substance satisfactory to the Corporation, make available upon reasonable notice and during normal business hours, for inspection by the Investors holding such Registrable Shares, any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by the Investors or underwriter (collectively, the "Inspectors"), all pertinent financial and other records, pertinent corporate documents and properties of the Corporation (collectively, the 7 10 "Records"), as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Corporation's officers, directors and employees to supply all information (together with the Records, the "Information") reasonably requested by any such Inspector in connection with such registration statement. Any of the Information which the Corporation determines in good faith to be confidential, and of which determination the Inspectors are so notified, shall not be disclosed by the Inspectors unless (i) the disclosure of such Information is necessary to avoid or correct a misstatement or omission in the registration statement, provided that such disclosure is made only after consultation with the Corporation, (ii) the release of such Information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or (iii) such Information has been made generally available to the public, other than by any party hereto in breach of its obligations hereunder; the Investors agree that they will, upon learning that disclosure of such Information is sought in a court of competent jurisdiction, give notice to the Corporation and allow the Corporation, at the Corporation's expense, to undertake appropriate action to prevent disclosure of the Information deemed confidential; (j) use its best efforts to obtain from its independent certified public accountants "cold comfort" letters in customary form and at customary times and covering matters of the type customarily covered by cold comfort letters under the circumstances; (k) use its best efforts to obtain from its counsel an opinion or opinions in customary form; (l) provide a transfer agent and registrar (which may be the same entity and which may be the Corporation) for such Registrable Shares; (m) issue to any underwriter to which the Investors holding such Registrable Shares may sell shares in such offering certificates evidencing such Registrable Shares; (n) list such Registrable Shares on any national securities exchange on which any shares of the Common Stock are listed or, if the Common Stock is not listed on a national securities exchange, use its best efforts to qualify such Registrable Shares for inclusion on the automated quotation system of the National Association of Securities Dealers, Inc.

SECTION 8. INDEMNIFICATION. (a) In connection with any registration of any Registrable Shares under the Securities Act pursuant to this Agreement, the Corporation shall indemnify and hold harmless the holders of Registrable Shares, each underwriter, broker or any other person acting on behalf of the holders of Registrable Shares and each other person, if any, who controls any of the foregoing persons within the meaning of the Securities Act against any losses, claims, damages or liabilities, joint or several (or actions in respect thereof), to which any of the foregoing persons 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 an untrue statement or allegedly untrue statement of a material fact contained in the registration statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares, 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, with respect to any prospectus, necessary to make the statements therein in light of the circumstances under which they were made not misleading, or any violation by the Corporation of the Securities Act or state securities or blue sky laws applicable to the Corporation and relating to action or inaction required of the Corporation in connection with such registration or qualification under such state 9 12 securities or blue sky laws; and shall reimburse the holders of Registrable Shares, such underwriter, such broker or such other person acting on behalf of the holders of Registrable Shares and each such controlling person for any legal or other expenses reasonably incurrwith investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Corporation shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action (including any legal or other expenses incurred) arises out of or is based upon an untrue statement or allegedly untrue statement or omission or alleged omission made in said registration statement, preliminary prospectus, final prospectus, amendment, supplement or document incident to registration or qualification of any Registrable Shares in reliance upon and in conformity with written information furnished to the Corporation through an instrument duly executed by any holder of Registrable Shares or his or its counsel or underwriter specifically for use in the preparation thereof; provided further, however, that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any untrue statement, allegedly untrue statement, omission or alleged omission made in any preliminary prospectus but eliminated or remedied in the final prospectus (filed pursuant to Rule 424 of the Securities Act), such indemnity agreement shall not inure to the benefit of any Investor, underwriter, broker or other person acting on behalf of holders of the Restricted Shares from whom the person asserting any loss, claim, damage, liability or expense purchased the Restricted Shares which are the subject thereof, if a copy of such final prospectus had been made available to such person and such Investor, underwriter, broker or other person acting on behalf of holders of the Registrable Shares and such final prospectus was not delivered to such person with or prior to the written confirmation of the sale of such Registrable Shares to such person. (b) In connection with any registration of Registrable Shares under the Securities Act pursuant to this Agreement, each holder of Registrable Shares shall severally and not jointly indemnify and hold harmless (in the same manner and to the same extent as set forth in the preceding paragraph (a) of this Section 8) the Corporation, each director of the Corporation, each officer of the Corporation who shall sign such registration statement, each underwriter, broker or other person acting on behalf of the holders of Registrable Shares and each person who controls any of the foregoing persons within the meaning of the Securities Act with respect to any statement or omission from such registration statement, any preliminary prospectus or final prospectus contained therein or otherwise filed with the Commission, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares, if such statement or omission was made in reliance upon and in conformity with written information furnished to the Corporation or such underwriter specifically for use in connection with the preparation of such registration statement, preliminary prospectus, final prospectus, amendment, supplement or document; provided, however, that the maximum amount of liability in respect of such indemnification shall be limited, in the case of each seller of Registrable Shares, to an amount equal to the net proceeds actually received by such Seller from the sale of Registrable Shares effected pursuant to such 10 13 registration. (c) Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in the preceding paragraphs of this Section 8, such indemnified party will, if a claim in respect thereof is made against an indemnifying party, give written notice to the latter of the commencement of such action. The failure of any indemnified party to notify an indemnifying party of any such action shall not (unless such failure shall have a material adverse effect on the indemnifying party) relieve the indemnifying party from any liability in respect of such action that it may have to such indemnified party on account of this Section 8. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided, however, that if any indemnified party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such indemnified party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity agreement provided in this Section 8, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party (but shall have the right to participate therein with counsel of its choice) and such indemnifying party shall reimburse such indemnified party and any person controlling such indemnified party for that portiny counsel retained by the indemnified party which is reasonably related to the matters covered by the indemnity agreement provided in this Section 8. If the indemnifying party is not entitled to, or elects not to, assume the defense of a claim, it will not be obligated to pay the fees and expenses of more than one counsel with respect to such claim. (d) If the indemnification provided for in this Section 8 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action 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 statements or omissions which resulted in such loss, claim, damage, liability or action as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of 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 or alleged 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, 11 14 access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and equitable if contribution pursuant hereto were determined by pro rata allocation or by any other method or allocation which does not take account of the equitable considerations referred to herein). No person guilty of fraudulent misrepresentation shall be entitled to contribution from any person. SECTION 9. UNDERWRITING AGREEMENT. Notwithstanding the provisions of Sections 5, 6, 7 and 8, to the extent that the Investors shall enter into an underwriting or similar agreement, which agreement contains provisions covering one or more issues addressed in such Sections, the provisions contained in such agreement addressing such issue or issues shall control. SECTION 10. INFORMATION BY HOLDER. The Investors shall furnish to the Corporation such written information regarding the Investors and the distribution proposed by the Investors as the Corporation may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement. SECTION 11. EXCHANGE ACT COMPLIANCE. From the Registration Date or such earlier date as a registration statement filed by the Corporation pursuant to the Exchange Act relating to any class of the Corporation's securities shall have become effective, the Corporation shall comply with all of the reporting requirements of the Exchange Act applicable to it (whether or not it shall be required to do so, but specifically excluding Section 14 of the Exchange Act if not then applicable to the Corporation) and shall comply with all other public information reporting requirements of the Commission which are conditions to the availability of Rule 144 for the sale of the Common Stock. The Corporation shall cooperate with the Investors in supplying such information as may be necessary for the Investors to complete and file any information reporting forms presently or hereafter required by the Commission as a condition to the availability of Rule 144.
