(a) Request for Registration. If, at any time after the date hereof, the Company shall receive from the Requisite Holders a written request that the Company effect the registration under the Securities Act of the resale of Registrable Securities held by such Requisite Holders (a "Demand Registration"), then the Company shall: (i) promptly give written notice of the proposed registration to all other Holders; (ii) use its best efforts to effect, as soon as practicable, the registration under the Securities Act of the Registrable Securities which the Company has been so requested to register, together with all or such portion of the Registrable Securities of any Holders joining in such request as are specified in a written request received by the Company within 20 days after the Company mails such written notice in accordance with the registration procedures set forth in Section 6 hereof and to keep effective for 120 days after the effective date; PAGE -3- provided, however, that the Company shall not be obligated to take any action to effect any such registration under the Securities Act: (A) after the Company has effected four such registrations pursuant to this Section 2 which has been declared or ordered effective and pursuant to which securities have been sold; or (B) If less than the Requisite Securities are requested to be included in the registration. (iii) the Holder shall be entitled to make a request for a shelf registration pursuant to Rule 415 of the Securities Act, which request may be for a shelf registration of not more than 12 month duration. This shall count as one demand right under Section 2(a)(ii)(A). Subject to the foregoing clauses 2(a)(ii)(A), 2(a)(ii)(B) and 2(a)(iii) the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable, and in any event within 90 days, after receipt of the request or requests of the Requisite Holders; provided, however, that if the Company shall within five days of such demand furnish to such Holder a certificate signed by the president of the Company stating that in the good faith judgment of the board of directors of the Company, it would be detrimental to the Company or its shareholders for such registration statement to be filed on or before the date filing would be required and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer such filing for a reasonable period not to exceed 90 days from receipt of such Holder's request. The Company's right to delay such registration as set forth in the previous sentence may only be exercised one time during any twelve month period. (b) Underwritten Demand Registrations. The offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering except for one such Demand Registration which may be for a shelf registration in compliance with the provisions of this Section 2. In the event the managing underwriter or underwriters of the Demand Registration advise the Company and the Requisite Holders in writing that the total amount of Registrable Securities requested to be included in such offering would exceed the maximum amount of securities which can be marketed at a price reasonably related to the current fair market value of such securities without adversely affecting such offering (the "Underwriters Maximum Number"), the Company will be required to include in such registration to the extent of the Underwriters Maximum Number: first, all of the Registrable Securities requested to be included in such registration by the Holders thereof, allocated pro rata among such Holders on the basis of the number of Registrable Securities requested to be included therein by each such Holder; and second, any equity securities requested to be included in such registration by the Company and any other holders of such securities, allocated as determined by the Company subject to any agreements between the Company and any such holders. (c) Selection of Underwriters. The managing underwriter or underwriters to PAGE -4- be used in connection with such registration shall be selected by the Requisite Holders holding a majority of the Registrable Securities being registered. The Company shall have the right to approve the selection of any such underwriters, which approval shall not be unreasonably withheld. (d) Underwriting Agreements. The Company shall (together with all Holders selling Registrable Securities) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by a majority in interest of the Requisite Holders, and each Holder selling Registrable Securities shall participate in such underwriting. (e) Withdrawal from Underwriting. If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the managing underwriter and the Requisite Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration, and such Registrable Securities shall not be transferred in a public distribution prior to 60 days after the effective date of such registration, or such other shorter period of time as the underwriters may require. If by the withdrawal of such Registrable Securities a greater number of Registrable Securities held by other Holders may be included in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders who have included Registrable Securities in the registration the right to include additional Registrable Securities in the same proportion and manner used in determining the underwriter limitation in this Section 2. (f) Inclusion as a Demand Registration. For purposes of this Section 2, a registration will not count as a Demand Registration until it has become effective; provided, however, if the Requisite Holders withdraw their Registrable Securities (whether before or after the effectiveness of such registration) and not as a result of any wrong doing by the Company, or if as a result of any action by the managing underwriters or underwriters, such demand will count as a Demand Registration for purposes of this Section 2 unless the Requisite Holders pay all of the Registration Expenses associated with such attempted registration. Section 3. Piggyback Registration. (a) Right to Include Registrable Securities. Whenever the Company proposes to register the sale of any of its equity securities under the Securities Act other than on Form S-4 or Form S-8 promulgated under the Securities Act or any similar form then in effect, the Company shall give written notice thereof to each Holder as soon as practicable (but in any event at least 30 days before such filing), offering such Holder the opportunity to register on such registration statement such number of Registrable Securities as such Holder may request in writing, subject to the provisions of section 3(b), not later than 20 days after the date of the giving of such notice (a "Piggyback Registration"). Upon receipt by the Company of any such request, the Company shall use reasonable efforts to, or in the case of an underwritten offering, to cause the managing underwriter or underwriters to, include such Registrable Securities in such registration statement (or in a separate registration statement concurrently filed) and to cause such registration statement to PAGE -5- become effective with respect to such Registrable Securities in accordance with the registration procedures set forth in Section 6 hereof. If the Company's registration is to be effected pursuant to an underwritten offering, Registrable Securities registered pursuant to this Section 3 shall be distributed in accordance with such offering. Notwithstanding the foregoing, if at any time after giving written notice of its intention to register its equity securities and before the effectiveness of the registration statement filed in connection with such registration, the Company determines for any reason either not to effect such registration or to delay such registration, the Company may, at its election, by delivery of written notice to each Holder (A) in the case of a determination not to effect registration, relieve itself of its obligation to register the Registrable Securities in connection with such registration or (B) in the case of a determination to delay registration, delay the registration of such Registrable Securities for the same period as the delay in the registration of such other equity securities. Each Holder requesting inclusion in a registration pursuant to this Section 3 may, at any time before the effective date of the registration statement relating to such registration, revoke such request by delivering written notice of such revocation to the Company (which notice shall be effective only upon receipt by the Company); provided, however, that if the Company, in consultation with its financial and legal advisors, determines that such revocation would materially delay the registration or otherwise require a recirculation of the prospectus contained in the registration statement, then such holder shall have no right to so revoke its request. (b) Priority in Piggyback Registration. Notwithstanding the foregoing, with respect to a Piggyback Registration that is underwritten and with respect to which the managing underwriter or underwriters advise the Company of an Underwriters Maximum Number, then the Company will so notify all Holders requesting inclusion in such registration and will be required to include in such registration, to the extent of the Underwriters Maximum Number: first, any equity securities that the Company proposes to sell for its own account; second, the Registrable Securities requested by Holders to be included in such registration prior to any other holders of equity securities having piggyback registration rights; provided, however, in no event will the number of shares to be included by the Holder be reduced to less than 25% of the total Registrable Securities; and third, to the extent that the Underwriters Maximum Number has not been filled by the application of the preceding clauses, any further equity securities that the Company proposes to sell for its own account and/or any equity securities requested to be included in such registration by other holders of such securities, allocated as determined by the Company subject to agreements between the Company and any such holders. (c) Selection of Underwriters. If any Piggyback Registration is in the form of an underwritten offering, the managing underwriter or underwriters and any additional investment bankers and managers to be used in connection with such registration shall be selected by the Company (subject to any separate agreement with the holders on behalf of which a secondary underwritten offering is being made). (d) Underwriting Agreements. All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in PAGE -6- customary form with the managing underwriter selected for such underwriting by the Company, and each Holder selling Registrable Securities shall participate in such underwriting. (e) Withdrawal from Underwriting. If any Holder or other holder disapproves of the terms of any such underwriting, he may elect to withdraw therefrom by written notice to the Company and the managing underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration, and shall not be transferred in a public distribution prior to 180 days after the effective date of the registration statement relating thereto, or such other shorter period of time as the underwriters may require. Sales under Rule 144 shall not be considered a public distribution for purposes of this paragraph. (f) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this Section 3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. Section 4. Market Standoff. If the Company at any time shall register the offer and sale of shares of Common Stock to the public under the Securities Act (including any registration pursuant to Sections 2 or 3), the Holders shall not sell publicly, make any short sale of, grant any option for the purchase of, or otherwise dispose publicly of, any Registrable Securities (other than those shares of Common Stock included in such registration pursuant to Sections 2 or 3) without the prior written consent of the Company for a period designated by the Company in writing to the Holders, 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 120 days after the effective date of such registration statement. The Company shall obtain the agreement of any person permitted to sell shares of stock in a registration to be bound by and to comply with this Section 4 as if such person was a Holder hereunder. Section 5. Expenses of Registration. All Registration Expenses incurred in connection with the one Demand Registration and the Piggyback Registrations shall be borne by the Company. All Selling Expenses relating to securities so registered as well as all Registration Expenses relating to Demand Registrations and Piggyback Registrations not required to be borne by the Company shall be borne by the holders of such securities pro rata on the basis of the number of shares of securities so registered on their behalf. Section 6. Registration Procedures. If and whenever the Company is required by the provisions of Section 2 or 3 hereof to use its best efforts to effect promptly the registration of Registrable Securities, the Company shall: (a) Prepare and file with the Commission a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become and remain effective as provided herein;

provided, however, that (i) such period shall be extended for a period of time equal to the period the Holder refrains from selling any securities included in such registration at the request of an underwriter of Common Stock (or other securities) of the Company; and (ii) in the case of any registration of Registrable Securities on Form S-3 which are intended to be offered on a continuous or delayed basis, such period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold, provided that Rule 415 permits an offering on a continuous or delayed basis, and provided further that applicable rules under the Securities Act governing the obligation to file a post-effective amendment permit, in lieu of filing a post-effective amendment that (I) includes any prospectus required by Section 10(a)(3) of the Securities Act or (II) reflects facts or events representing a material or fundamental change in the information set forth in the registration statement. the incorporation by reference of information required to be included in (I) and (II) above to be contained in periodic reports filed pursuant to Section 13 or 1 5(d) of the Exchange Act in the registration statement;

provided, however, that the Company will not be required to qualify generally to do business, subject itself to general taxation or consent to general service of process in any jurisdiction where it would not otherwise be required to do so but for this paragraph (g);
