Each Operating Agreement is a valid, binding and enforceable agreement of PSIL and, to the Knowledge of PSIL, the other parties thereto. Except as indicated in the Disclosure Schedule, there has not occurred any breach or default under any Operating Agreement on the part of PSIL or, to the Knowledge of PSIL, any other parties thereto. Except as indicated in the Disclosure Schedule, no event has occurred which with the giving of notice or the lapse of time, or both, would constitute a default under any Operating Agreement on the part of PSIL, or, to the Knowledge of PSIL, any of the other parties thereto. There is no dispute between the parties to any Operating Agreement as to the interpretation thereof or as to whether any party is in breach or default thereunder, and no party to any Operating Agreement has indicated its intention to, or suggested it may evaluate whether to, terminate any Operating Agreement.

Section 3.17. Brokers and Finders. PSIL has not entered into any contract, arrangement or understanding with any person or firm which may result in the obligation of Parent, Newco, PSIL or the Principal to pay any finder’s fees, brokerage or agent commissions or other like payments in connection with the transactions contemplated hereby.

Section 3.18. Purchase for Own Account. The rights under the Royalty Agreement to be acquired by PSIL pursuant to the terms hereof (the “Rights”) are being or will be acquired by PSIL for its own account and with no intention of distributing or reselling the Rights or any part thereof in any transaction that would be in violation of the securities laws of the United States of America, or any state, without prejudice, however, to the rights of PSIL at all times to sell or

otherwise dispose of all or any part of the Rights under an effective registration statement under the Securities Act, or under an exemption from such registration available under the Securities Act. PSIL represents that it is experienced in evaluating companies such as Newco and has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment and has the ability to suffer the total loss of his investment. PSIL further represent that they have had the opportunity to ask questions of and receive answers from executive officers of Newco concerning the terms and conditions of the offering of Rights and to obtain additional information to the satisfaction of PSIL. PSIL understands that the Rights will not be registered at the time of their issuance under the Securities Act for the reason that the sale provided for in this Agreement is exempt pursuant to Section 4(2) of the Securities Act and that the reliance of Newco on such exemption is predicated in part on the representations of PSIL set forth herein.

(a) PSIL will not be insolvent immediately after the Closing. As used in this Section, “insolvent” means that the sum the debts and other probable liabilities of PSIL exceed the present fair saleable value of the assets of PSIL.

(b) Immediately after giving effect to the consummation of the Transactions, PSIL’s only significant asset will be its rights under the Royalty Agreement and PSIL will have no Known liabilities, other than liabilities to persons or entities that have agreed in writing to defer payment until funds are available under the Royalty Agreement or otherwise. Accordingly, immediately after giving effect to the consummation of the Transactions, (i) PSIL will be able to pay its Known liabilities as they become due in the usual course of its business, (ii) PSIL will not have unreasonably small capital with which to conduct its present or proposed business (as it does not propose to engage in active business operations after Closing), and (iii) taking into account all pending and threatened litigation Known to PSIL, final judgments against PSIL in actions for money damages are not reasonably anticipated to be rendered at a time when, or in amounts such that, PSIL will be unable to satisfy any such judgments promptly in accordance with their terms (taking into account the maximum probable amount of such judgments in any such actions and the earliest reasonable time at which such judgments might be rendered) as well as all Known liabilities of PSIL. The cash available to PSIL, after taking into account all other anticipated uses of the cash, will be sufficient to pay promptly in accordance with their terms all Known liabilities. For purposes of this Section 3.19, the term “Known liabilities” shall mean debts and judgments of PSIL which (i) are now due and payable, (ii) will become due and payable after Closing with respect to which PSIL has incurred a contractual obligation as of Closing, or (iii) PSIL anticipates it

will incur in the near term after Closing, including but not limited to amounts arising from pending and threatened litigation of PSIL.

Section 3.20. Disclosure. No representation or warranty of PSIL or the Principal set forth hereunder or in the schedules attached hereto or in any certificate delivered pursuant to Section 7.3(a) contains any untrue statement of the material fact or omits to state a material fact necessary in order to make the statements contained herein or therein not misleading.
