Any transfer or purported transfer of the Debentures (1) not made pursuant to the terms of the Debentures or (2) not properly noticed to the Transfer Agent shall be null and void ab initio and shall not be given effect thereto by the Transfer Agent. The Transfer Agent shall not be required to acknowledge any transfer of the Debentures unless accompanied by written confirmation thereof from the Company and the Holders. 3. PAYING AGENT.

Accordingly, all payments of principal required of the Company related to the Debentures shall be made to the Transfer Agent for the account and benefit of the holders of such Debentures as registered on the books of the Transfer Agent ("Registered Debentureholder").

All payments of interest shall be made directly to the Registered Debentureholders by the Company, which shall notify the Transfer Agent of such payments when made. 4. ACCOUNTING AGENT. The Transfer Agent shall act as the accounting agent of the Company and the Registered Debentureholders and shall establish and maintain a book entry system of accounting for the Debentures (the "Accounting Ledger") crediting (reducing) the outstanding balance owed thereunder by all (i) payments of principal made by the Company to the Transfer Agent as paying agent as required pursuant to Section 3 above, (ii) by the appropriate amount upon delivery of Converted Stock to the applicable Registered Debentureholders following receipt of a Notice of Conversion (as each such term is defined in Section 5 below), and (iii) by payments in cash of interest made by the Company to the Registered Debentureholders of which notice is given to the Transfer Agent pursuant to Section 3 above. At such time as the remaining sum due and owing on any Debenture as reflected on the Accounting Ledger is zero following the procedures described in this Agreement, the Transfer Agent shall return such Debenture to the Company marked "Paid in Full." 5. ISSUANCE OF CONVERTED SHARES. (a) Consistent with Section 3.2 of each Debenture, in order to convert all or a portion of a Debenture into common shares of the Company (the "Converted Stock"), a Registered Holder shall deliver written notice (each, a "Notice of Conversion") to the Transfer Agent of the portion of the Debenture it elects to so convert and a calculation of the number of shares of Converted Stock to be issued upon such conversion. Upon receipt by the Transfer Agent of any such Notice of Conversion (including receipt via facsimile) from any Registered Holder, the Transfer Agent shall immediately deliver a copy thereof to the Company, via facsimile, requesting the Company to confirm the number of shares of Converted Stock to be issued to such Registered Holder in connection therewith. The Company shall, upon receipt thereof, promptly confirm or dispute the number of shares of Converted Stock to be issued to the Registered Holder, providing written notice thereof via facsimile to the Transfer Agent and the Registered Holder (the "Company Notice"). In the event the Company confirms the number of shares of Converted Stock to be so issued, it shall, as part of the Company Notice, direct the Transfer Agent to issue such shares of Converted Stock to the Registered Holder. In the event the Company disputes the number of shares of Converted Stock to be so issued, the Company and the Registered Holder shall immediately, in good faith, seek to resolve such dispute. In the event the Company and the Registered Holder cannot resolve such dispute, each party reserves all rights and remedies against the other associated with such Notice of Conversion. BOOK ENTRY TRANSFER AGENT AGREEMENT - Page 3 (b) The Transfer Agent shall not be required to issue shares of Converted Stock unless and until receipt (including via facsimile) of written notice from either (i) the Company, confirming the number of shares of Converted Stock to be issued or (ii) the Registered Holder and the Company, setting forth the number of shares of Converted Stock to be issued. (c) Reference is hereby made to that certain Registration Rights Agreement appended to the Subscription Agreement. At such time as a Registration Statement as contemplated therein has been declared effective by the Securities and Exchange Commission covering the resale of the Converted Stock, the Company shall cause its legal counsel to deliver to the Transfer Agent an opinion certifying that the Converted Stock may be sold by the Registered Holder receiving such shares upon conversion of the Debentures, with the purchaser thereof receiving certificates without restrictive legend, which opinion shall remain effective so long as such Registration Statement remains in full force and effect. In the event that, at any time, the Registration Statement ceases to be effective, the Company or its legal counsel shall immediately deliver written notice thereof to the Transfer Agent and the Registered Holders stating that the opinion of the Company's legal counsel may no longer be relied upon by the Transfer Agent (unless and until any new Registration Statement is so declared effective with an accompanying opinion to that effect of the Company's legal counsel). Upon the receipt of any Notice of Conversion while a Registration Statement is effective, the Converted Stock described above may be sold by the Registered Holder receiving such shares upon conversion of the Debentures, with the purchaser thereof receiving certificates without restrictive legend. 6. TERMINATION. This Agreement shall terminate promptly upon the earlier to occur of (1) written demand by all of the Registered Debentureholders of their respective Debentures or (2) no sum remains due and owing under any of the Debentures. Notwithstanding the foregoing, the Transfer Agent may terminate its obligations under this Agreement at such time as the Transfer Agent no longer serves as the transfer agent for the Company's common stock, by delivery of written notice thereof to the Registered Holders and the Company. Upon delivery of such notice, the Transfer Agent shall deliver the original Debentures to Infinity, on behalf of all Registered Holders, together with a copy of the Accounting Ledger (with a corresponding copy delivered to the Company). 7. FEES. The Company hereby agrees to pay the Transfer Agent for all services rendered hereunder. 8. NOTICES.

NONCONTRAVENTION.

Accordingly, the Company agrees that the instructions and procedures set forth above BOOK ENTRY TRANSFER AGENT AGREEMENT - Page 5 in this Agreement constitute irrevocable instructions, directions and authorizations to the Transfer Agent and that the Transfer Agent is authorized to disregard any written or oral communication received by it from the Company or otherwise that could in any way be construed to constitute an authorization or direction for the Transfer Agent to act contrary to, or to not faithfully comply with, the irrevocable instruction, direction and authorization set forth herein. Each of the Registered Debentureholders is an intended third party beneficiary of these irrevocable instructions. 10. INDEMNIFICATION. The Company agrees to indemnify and hold harmless the Transfer Agent, each officer, director, employee and agent of the Transfer Agent, and each person, if any, who controls the Transfer Agent within the meaning of the Securities Act of 1933, as amended (the "Act") or the Securities Exchange Act of 1934, as amended (the "Exchange Act") against any losses, claims, damages, or liabilities, joint or several, to which it, they or any of them, or such controlling person, may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon the performance by the Transfer Agent of its duties pursuant to the Agreement; and will reimburse the Transfer Agent, and each officer, director, employee and agent of the Transfer Agent, and each such controlling person for any legal or other expenses reasonably incurred by it or any of them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any case if such loss, claim, damage or liability arises out of or is based upon any action not taken in good faith, or any action or omission that constitutes gross negligence or willful misconduct. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the Company under this Section, notify in writing the Company of the commencement thereof, and failure so to notify the Company will relieve the Company from any liability under this Section as to the particular item for which indemnification is then being sought but not from any other liability which it may have to any indemnified party (unless such failure to so notify the Company does not prejudice in any material respect the rights and defenses of the Company). In case any such action is brought against any indemnified party, and it notifies the Company of the commencement thereof, the Company will be entitled to assume the defense thereof, with counsel who shall be to the reasonable satisfaction of such indemnified party. The Company shall not be liable to any such indemnified party on account of any settlement of any claim of action effected without the consent of the Company. 11. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the state of New York, without giving effect to conflicts of law rules of such jurisdiction.
