(iii) Unless pursuant to a private sale effected under applicable formal or informal SEC interpretation or guidance, such as a so-called “4(1) and a half” sale pursuant to a legal opinion provided by Purchaser to the Company in form and substance reasonably acceptable to Company.

The Company will not require such a legal opinion (x) in any transaction in compliance with Rule 144 or (y) in any transaction in which the Purchaser distributes the securities in question to an Affiliate of such Purchaser; provided that each transferee agrees in writing to be subject to the terms of this Agreement including this paragraph (e).

writing signed by the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

Section 6.3 Reimbursement of Legal and Other Expenses. If any amount owing to the Purchasers under any Transaction Document shall be collected through enforcement of this Agreement, any Transaction Document or restructuring of the Loan in the nature of a work-out, settlement, negotiation, or any process of law, or shall be placed in the hands of third Persons for collection, the Company shall pay (in addition to all monies then due in respect of the Loan or otherwise payable under any Transaction Document) reasonable attorneys’ and other reasonable fees and out-of-pocket expenses incurred by the Purchasers in respect of such collection. Promptly following the closing of the Loan contemplated by this Agreement, the Company shall reimburse the Purchasers for the reasonable fees and out of pocket expenses incurred by Fulbright & ▇▇▇▇▇▇▇▇ L.L.P., counsel to the Purchasers, in an amount not to exceed $50,000.

Section 6.4 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York applicable to contracts made and to be performed in such State. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, employees or agents) may be commenced non-exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the non-exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. The parties hereby waive all rights to a trial by jury.

Section 6.5 Successors and Assigns. This Agreement shall bind and inure to the respective successors and assigns of the Parties, except that Company may not assign or otherwise transfer all or any part of its rights under the Transaction Documents without the prior written consent of a Majority in Interest of the Purchasers; provided that the Company may assign or transfer all or any part of its rights under the Transaction Documents without the prior written consent of the Purchasers in connection with a Change of Control if the Purchasers holding a Majority in Interest waive the put right provided for in Section 5.3.

Section 6.6 Entire Agreement; Amendments. The Transaction Documents contain the entire understanding of the Parties with respect to the matters covered thereby and supersede any and all other written and oral communications, negotiations, commitments and writings with respect thereto. The provisions of this Agreement and the Transaction Documents may be waived, modified, supplemented or amended by an instrument in writing signed by the

authorized officer of each the Company and Purchasers holding a Majority in Interest. Notwithstanding the foregoing:

(a) In the event that any such amendment or waiver would, by its terms, treat in a discriminatory manner a single Purchaser (or group of Purchasers), such amendment or waiver shall also require the written consent of the Purchaser so adversely affected (or a majority in interest of the group of such Purchasers); and

(b) any provision hereof may be waived by the waiving party on such party’s own behalf, without the consent of any other party.

The Company shall give prompt written notice of any amendment or waiver hereunder to any party that did not consent in writing thereto. Any amendment, termination or waiver effected in accordance with this Section 6.6 shall be binding on each Party and all of such Party’s successors and permitted assigns, whether or not any such Party, successor or assignee entered into or approved such amendment or waiver.

Section 6.7 Severability. If any provision of this Agreement shall be invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. The Parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provision.

Section 6.8 Counterparts. This Agreement may be executed in several counterparts, and by each Party on separate counterparts, each of which and any photocopies and facsimile copies thereof shall be deemed an original, but all of which together shall constitute one and the same agreement.

Section 6.9 Survival.

(a) This Agreement and all agreements, representations and warranties made in the Transaction Documents, and in any document, certificate or statement delivered pursuant thereto or in connection therewith shall be considered to have been relied upon by the other Parties and shall survive the execution and delivery of this Agreement and the making of the Loan hereunder regardless of any investigation made by any such other Party or on its behalf, and shall continue in force until all amounts payable under the Transaction Documents shall have been fully paid in accordance with the provisions thereof, and the Purchasers shall not be deemed to have waived, by reason of making the Loan, any Event of Default that may arise by reason of such representation or warranty proving to have been false or misleading, notwithstanding that the Purchasers may have had notice or knowledge of any such Event of Default or may have had notice or knowledge that such representation or warranty was false or misleading at the time the Notes were purchased.

(b) The obligations of the Company and the Purchasers under the Transaction Documents that, by their terms, would survive the consummation of the transactions contemplated hereby, the repayment of the Loan, or the termination of this Agreement or any provision hereof, shall so survive and remain in full force and effect.

Section 6.10 Waiver. Neither the failure of, nor any delay on the part of, any Party in exercising any right, power or privilege hereunder, or under any other Transaction Document, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder, or under any other Transaction Document, preclude other or further exercise thereof or the exercise of any other right, power or privilege; nor shall any waiver of any right, power, privilege or default hereunder, or under any other Transaction Document, constitute a waiver of any other right, power, privilege or default or constitute a waiver of any default of the same or of any other term or provision. No course of dealing and no delay in exercising, or omission to exercise, any right, power or remedy accruing to the Purchasers upon any default under this Agreement, or any other agreement shall impair any such right, power or remedy or be construed to be a waiver thereof or an acquiescence therein; nor shall the action of the Purchasers in respect of any such default, or any acquiescence by it therein, affect or impair any right, power or remedy of the Purchasers in respect of any other default. All rights and remedies herein provided are cumulative and not exclusive of any rights or remedies otherwise provided by law.

Section 6.11 Indemnity.

(a) The Company shall, at all times, indemnify and hold the Purchasers (the “Indemnity”) and each of the Purchasers’ respective directors, partners, officers, employees, agents, counsel and advisors (each, an “Indemnified Person”) harmless in connection with any losses, damages, liabilities, penalties, or other expenses resulting from claims from third parties arising out of, or relating to, this Agreement or the Security Agreement or the use or intended use of the Loan other than in accordance with this Agreement, which an Indemnified Person may incur or to which an Indemnified Person may become subject (each, a “Loss”). The Indemnity shall not apply to the extent that a court or arbitral tribunal with jurisdiction over the subject matter of the Loss, and over the Purchasers or the Company, as applicable, and such other Indemnified Person that had an adequate opportunity to defend its interests, determines that such Loss resulted from the gross negligence or willful misconduct of the Indemnified Person, which determination results in a final, non-appealable judgment or decision of a court or tribunal of competent jurisdiction. The Indemnity is independent of and in addition to any other agreement of any Party under any Transaction Document to pay any amount to the Purchasers or the Company, as applicable, and any exclusion of any obligation to pay any amount under this subsection shall not affect the requirement to pay such amount under any other section hereof or under any other agreement.

(b) Promptly after receipt by an Indemnified Person under this Section 6.11 of notice of the commencement of any action (including any governmental action), such Indemnified Person shall, if a Loss in respect thereof is to be made against any Party (the “Indemnifying Person”) under this Section 6.11, deliver to the Purchaser a written notice of the commencement thereof, and the Purchaser shall have the right to participate in, and, to the extent the Purchaser so desires, to assume control of the defense thereof with counsel mutually satisfactory to the Purchaser and the Indemnified Person, as the case may be.

(c) An Indemnified Person shall have the right to retain its own counsel with the reasonable fees and expenses to be paid by the Purchaser if, in the reasonable opinion of counsel for the Purchaser, the representation by such counsel of the Indemnified Person and the Purchaser would be inappropriate due to actual or potential differing interests between such

Indemnified Person and any other party represented by such counsel in such proceeding. Notwithstanding the foregoing, the Purchaser shall pay for only one separate legal counsel for the Indemnified Persons, and such legal counsel shall be selected by the Purchaser. The failure to deliver written notice to the Purchaser within a reasonable time of the commencement of any such action shall not relieve the Purchaser of any liability to the Indemnified Person under this Section 6.11, except to the extent that the Purchaser is actually prejudiced in its ability to defend such action. The indemnification required by this Section 6.11 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable.

(d) Without prejudice to the survival of any other agreement of any of the Parties hereunder, the agreements and the obligations of the Parties contained in this Section 6.11 shall survive the termination of each other provision hereof and the payment of all amounts payable to the Purchasers hereunder.

Section 6.12 No Usury. The Transaction Documents are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or agreed to be paid to the Purchasers for the Loan exceed the maximum amount permissible under applicable law. If from any circumstance whatsoever fulfillment of any provision hereof, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstance the Purchasers shall ever receive anything which might be deemed interest under applicable law, that would exceed the highest lawful rate, such amount that would be deemed excessive interest shall be applied to the reduction of the principal amount owing on account of the Loan, or if such deemed excessive interest exceeds the unpaid balance of principal of the Loan, such deemed excess shall be refunded to the Company. All sums paid or agreed to be paid to the Purchasers for the Loan shall, to the extent permitted by applicable law, be deemed to be amortized, prorated, allocated and spread throughout the full term of the Loan until payment in full so that the deemed rate of interest on account of the Loan is uniform throughout the term thereof. The terms and provisions of this Section shall control and supersede every other provision of this Agreement and the Notes.

Section 6.13 Further Assurances. From time to time, the Company shall perform any and all acts and execute and deliver to the Purchasers such additional documents as may be necessary or as reasonably requested by the Purchasers to carry out the purposes of any Transaction Document or to preserve and protect the Purchasers’ rights as contemplated therein.

Section 6.14 Independent Transaction Documents. Each Transaction Document constitutes an independent agreement between the parties thereto (the “Transaction Parties”) and no Transaction Document shall be construed so as to affect the rights of the Transaction Parties to their rights and remedies under another Transaction Document.

Section 6.15 Time of the Essence. Time is of the essence in respect of the transactions contemplated by the Transaction Documents.
