In the event of the termination of this Agreement pursuant to the provisions of this Section 7, this Agreement shall become void and have no effect, without any liability on the part of any party hereto or its directors, officers or stockholders in respect of this Agreement, except for a breach of Section 21 hereof and except that nothing herein shall limit the right of either party to seek damages from the other for breach of this Agreement.

8. Adjustments for Dividends and Other Distributions; Stock Splits, etc. In the event of a change in the number of Shares prior to or on the Settlement Date by virtue of a stock split, stock dividend, split-up, recapitalization or other similar transactions, the Company shall deliver to Purchaser on the Settlement Date, without change in the Purchase Price, that number of shares of Common Stock as adjusted for such stock split, stock dividend, split-up, recapitalization or other similar transactions, on the Settlement Date as a result of such transactions and all such shares shall be "Shares" under this Agreement.

9. Registration Rights.

(a): From and after the Settlement Date, Purchaser may deliver a written request to the Company, which request shall state (i) the aggregate number of Shares which are proposed to be sold in a public offering, (ii) whether such Shares will be disposed of through an underwriter (an "Underwritten Offering") or otherwise, and (iii) shall request that the Company effect a registration under the Securities Act of all or part of the Shares then owned by Purchaser. Upon receipt of such request, the Company will promptly use its best efforts to effect the registration (the "Registration") under the Securities Act of the Shares which Purchaser has so requested to register so as to permit the disposition (in accordance with the intended methods thereof as aforesaid) by Purchaser of the Shares so to be registered.

If Purchaser requests an Underwritten Offering, the Company shall enter into an agreement with a managing underwriter selected by Purchaser and named in such request and with such other underwriters as Purchaser shall from time to time name, which agreement shall contain terms

customary for a secondary distribution. The Company shall have the right to approve any and all underwriters selected by Purchaser, which approvals shall not be unreasonably withheld.

For the purposes of Sections 9 through 13 of this Agreement, Shares shall also mean shares of Common Stock which become outstanding after the Settlement Date, and securities issued in respect of the Shares.

(b): If the managing underwriter for an Underwritten Offering notifies Purchaser that it is able to dispose of fewer Shares than the aggregate number which Purchaser has requested to be registered (such difference to be referred to as the "Undisposed Shares"), then the number of Shares to be registered on behalf of Purchaser shall be reduced by such difference.
(c): Purchaser may make the request for the Registration only once; provided, however, that in the event that an Underwritten Offering results in Undisposed Shares, then, Purchaser may subsequently request a Registration pursuant to Section 9(a) one or (to the extent that subsequent notice or notices are of Underwritten Offerings which resulted in Undisposed Shares) more additional times, to the extent necessary to register on behalf of Purchaser that number of Shares equal to the Undisposed Shares which resulted from the first Registration.

10. Registration of Shares by the Company. If the Company proposes to register on a general form for registration under the Securities Act a sale, disposition or transfer by the Company or any other person of any Common Stock (otherwise than pursuant to Section 9 of this Agreement, a registration relating solely to the sale of Common Stock to participants in a share plan of the Company or any of its subsidiaries or a registration relating solely to a reorganization or other transaction described under Rule 145 of the Securities Act) it will at each such time give written notice to Purchaser of its intention to do so and, upon the written request of Purchaser given within ten (10) days after mailing of any such notice (which request of such entity shall specify the number of Shares intended to be sold or disposed of by such entity and describe the nature of any proposed sale or other disposition thereof), the Company will use its best efforts to cause all such Shares to be registered under the Securities Act to the extent requisite to permit the sale or other disposition, in accordance with the method described in the notice; provided, however, that Purchaser shall have no right to participate in any Underwritten Offering by the Company in connection with Shares to be registered pursuant to this Section 10, notwithstanding their rights to have Shares registered pursuant to such Section; provided further, that the Company may require Purchaser to agree not to sell or otherwise dispose of such shares pursuant to the registration statement for a period not exceeding 90 days after the closing of the sale of Common Stock to an underwriter (the "Waiting Period") to the extent that the managing underwriter of the proposed public offering of securities for which the registration statement was to be filed delivers to Purchaser a letter stating that such sales or other disposition within such Waiting Period could materially and adversely affect such public offering. In the event of a disagreement in good faith between the parties hereto and the managing underwriter as to the length of the Waiting Period or any other matters relating to a Registration pursuant to Sections 9 through 13 of this Agreement, the decision of any mutually agreed upon third party, shall control.

11. Certain Obligations Regarding Registration.

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, 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 will not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.
