Section 9.    Amendment to Section 7.25. The Agreement is hereby amended by deleting Section 7.25 in its entirety and inserting in lieu thereof the following:

“Section 7.25 Restrictions on Transfer; Right of First Offer.

(a)    Except as permitted pursuant to paragraph (b) below or in accordance with the procedure set forth in paragraph (c) below, without the prior written consent of the Purchaser, the Seller shall not, directly or indirectly (i) sell, assign, transfer (including by operation of Law), dispose of or otherwise transfer (each, a “Transfer”) any shares of Series B Convertible Preferred Stock or (ii) deposit any shares of Series B Convertible Preferred

Stock into a voting trust or enter into a voting agreement, arrangement or understanding or grant any proxy or power of attorney with respect thereto.

(b) Notwithstanding the foregoing paragraph (a), the Seller may Transfer shares of Series B Convertible Preferred Stock (including any Purchaser Common Shares issuable upon conversion of shares of Series B Convertible Preferred Stock) to any of its Affiliates; provided, however, that (i) such Transfer in not in violation of any Securities Laws and (ii) the respective transferee shall, as a condition to such Transfer, execute and deliver to the Purchaser an agreement in writing by which such transferee shall agree to receive the benefits of Section 4.6 (but not the obligation to make the payment of the Resolution Payment Amount to the Purchaser, which obligation, for the avoidance of doubt, shall remain solely the obligation of the Seller), Section 4.10, Section 4.11 and Section 4.12 and be bound by Section 4.10 and Section 7.25(c) as if it were subject to such provisions as the “Seller.” Following any Transfer of share(s) of Series B Convertible Preferred Stock pursuant to this Section 7.25(b) and the assignment by the Seller of a portion of the Make Whole Payment and the Incremental Payment in accordance with Section 11.2(d) of this Agreement, the transferee/assignee shall have all of the rights of the Seller with respect to the share(s) of Series B Convertible Preferred Stock so Transferred under Section 4.6 (but not the obligation to make the payment of the Resolution Payment Amount to the Purchaser, which obligation, for the avoidance of doubt, shall remain solely the obligation of the Seller), Section 4.10, Section 4.11 and Section 4.12 and be bound by Section 4.10 and Section 7.25(c) as if it were subject to such provisions as a “Seller.”

(c) If the Seller (or an Affiliate of the Seller) (the “Prospective Seller”) desires to Transfer any shares of Series B Convertible Preferred Stock to any Person other than an Affiliate of the Prospective Seller (each, a “Prospective Buyer”), the Prospective Seller shall give (in accordance with Section 11.5) a written notice to the Purchaser (the “Offer Notice”) indicating that the Prospective Seller desires to make such Transfer and setting forth the number of shares of Series B Convertible Preferred Stock proposed to be Transferred (the “Offered Securities”), together with any other material terms and conditions of the proposed Transfer (including the proposed purchase price). The Purchaser shall have a five (5) Business Day period (the “Offer Period”) in which to agree, by delivery of written notice to the Prospective Seller (by hand delivery, courier or first-class mail (postage prepaid) to the address of the Prospective Seller shown on the books and records of the Purchaser), to purchase all, but not less than all, of the Offered Securities on the terms and conditions set forth in the Offer Notice. The giving of such notice to the Prospective Seller shall constitute an offer by the Purchaser to purchase all of the Offered Securities from the Prospective Seller on the terms and conditions set forth in the Offer Notice (the “Offer”). Upon the earlier to occur of (i) the full rejection of the Offer by the Purchaser and (ii) the expiration of the Offer Period without the Purchaser making the Offer, the Prospective Seller may, during the ninety (90) day period following the Offer Period (the “Transfer Period”), Transfer of all, but not less than all, of the Offered Securities on substantially the same or more favorable (as to the Prospective Seller) terms and conditions as were set forth in the Offer Notice at a purchase price in cash that is equal to ninety-five percent (95%) or more than the Offer Price; provided, however, that (i) such Transfer in not in violation of any

Securities Laws and (ii) the transferee shall, as a condition to such Transfer, execute and deliver to the Purchaser an agreement in writing by which such transferee shall agree to receive the benefits of Section 4.6 (but not the obligation to make the payment of the Resolution Payment Amount to the Purchaser, which obligation, for the avoidance of doubt, shall remain solely the obligation of the Seller), Section 4.10, Section 4.11 and Section 4.12 and be bound by Section 4.10 as if it were subject to such provisions as the “Seller” (a “Transferee Acknowledgment”). If the Prospective Seller does not consummate the Transfer of the Offered Securities within the Transfer Period, the Prospective Seller shall again comply with the procedures set forth in this Section 7.25(c) with respect to any proposed Transfer. The closing of any Transfer to the Purchaser pursuant to this Section 7.25(c) (an “Offer Sale”) shall take place within fifteen (15) Business Days after the Prospective Seller’s receipt of the Offer at the principal office of the Purchaser, or at such other time and place as the Prospective Seller and the Purchaser may mutually determine. At the closing of the Offer Sale, the Prospective Seller shall deliver to the Purchaser the Offered Securities free and clear of Encumbrance (other than pursuant to this Agreement), together with any necessary transfer tax stamps affixed or payment for any other transfer taxes and any other certificates, transfer powers or other documents that the Purchaser may reasonably request, and the Purchaser shall pay the purchase price to the Prospective Seller, by wire transfer of immediately available federal funds. Following the Transfer of share(s) of Series B Convertible Preferred Stock pursuant to this Section 7.25(c) and the assignment by the Prospective Seller of a portion of the Make Whole Payment and the Incremental Payment in accordance with Section 11.2(d) of this Agreement, the transferee/assignee shall have all of the rights of the Prospective Seller with respect to the share(s) of Series B Convertible Preferred Stock so Transferred under Section 4.6 (but not the obligation to make the payment of the Resolution Payment Amount to the Purchaser, which, for the avoidance of doubt, shall remain solely obligation of the Seller), Section 4.10, Section 4.11 and Section 4.12 and be bound by Section 4.10 as if it were subject to such provision as a “Seller.”

(d) Nothing in this Section 7.25 shall prohibit the Transfer of the Purchaser Common Shares received by the holder of shares of Series B Convertible Preferred Stock following (i) the conversion thereof pursuant to Section 6 of the Certificate of Designation or (ii) the repurchase thereof pursuant to Section 4.10 of this Agreement.”

Section 13.    Governing Law. This Amendment No. 4 (and any claim, controversy or dispute arising hereunder) shall be governed by and construed in accordance with the domestic law of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the state of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the state of Delaware. The parties irrevocably submit to the exclusive general jurisdiction of the Delaware Court of the Chancery and any state appellate court therefrom within the State of Delaware (or, only if the Delaware Court of the Chancery declines to accept jurisdiction over a particular matter, any state or federal court sitting in the State of Delaware) for the purposes of any suit, action, or other proceeding arising out of or relating to the matters contemplated herein and each of the parties hereby waives its right to a jury trial with respect to any such matter.
