RESTRICTIONS ON TRANSFER OF SERIES A PREFERRED STOCK

SECTION 2.1 Transfers Generally. Any Transfer not made in compliance with the requirements of this Agreement shall be null and void ab initio, shall not be recorded on the books of the Company or its transfer agent and shall not be recognized by the Company. Each Party acknowledges and agrees that any breach of this Agreement would result in substantial harm to the other parties hereto for which monetary damages alone could not adequately compensate. Therefore, the Parties unconditionally and irrevocably agree that any non-breaching Party shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Transfer Stock not made in strict compliance with this Agreement).

SECTION 2.2 Permitted Transfers.

(a) Subject to Section 2.3, each Holder may Transfer any Preferred Stock (a “Permitted Transfer”) to (i) other Holders and their respective Affiliates (including, for the avoidance of doubt, their limited partners and accounts or funds managed or advised by any Holder or its Affiliates) and (ii) other Persons reasonably acceptable to the Company; provided, that, in the case of the foregoing clauses (i) and (ii), each such Prospective Transferee shall be provide to the Company a properly completed and executed Internal Revenue Service (“IRS”) Form W-9 or appropriate IRS Form W-8 claiming complete exemption from dividend withholding tax before such Transfer shall be effective; provided, further, that no Transfers will be permitted to any Disqualified Institution without the prior written consent of the Company (which consent may be withheld, conditioned or delayed in its sole discretion), and no Transfer shall be made in violation of the Securities Act or any applicable state securities Laws or that results (or could reasonably be expected to result) in the Company being required to register the Preferred Stock pursuant to applicable securities Laws. In connection with any Permitted Transfer, such Prospective Transferee shall execute and deliver to the Company a Preferred Holder Joinder, in substantially the form attached hereto as Exhibit B, at the time of or prior to any Transfer (unless such Prospective Transferee is a Holder before giving effect to such Transfer).

(b) Notwithstanding Section 2.1, if an Event of Noncompliance shall occur and not be cured by the Company within the applicable cure period, for so long as such Event of Noncompliance is continuing, the Preferred Stock shall be freely transferable by any Holder at any time during the continuation of such Event of Noncompliance, subject to compliance with applicable securities Laws.

(c) The Company shall keep at its principal office a register for the registration of the Preferred Stock. Upon the surrender of any certificate representing any Preferred Stock at the Company’s principal office, the Company shall, upon the request of the Holder of such certificate, promptly (but in any event within three Business Days after such request) prepare, execute and deliver (at the Company’s expense) new certificates in exchange therefor representing Preferred Stock with an aggregate Stated Value represented by the surrendered certificate. Such certificate shall be registered in the name requested by the Holder of the surrendered certificate and shall represent the Stated Value of the Preferred Stock as is requested by the Holder of the surrendered certificate. Dividends shall accumulate on the aggregate Stated Value of the Preferred Stock represented by such new certificates from the date on which Dividends have been fully paid on the aggregate Stated Value of the Preferred Stock represented by the surrendered certificate. The issuance of such new certificates shall be made without charge to the Holders, and the Company shall pay for any cost incurred by the Company in connection with such issuance, including any documentary, stamp and similar issuance or transfer tax in respect of the preparation, execution and delivery of such new certificates pursuant to this Section 2.2(c). All transfers and exchanges of Preferred Stock shall be made promptly by direct registration on the books and records of the Company and the Company shall take all such other actions as may be required to reflect and facilitate all transfers and exchanges not prohibited by this Section 2.2(c).

2

(d) Upon receipt of evidence reasonably satisfactory to the Company (it being understood that an affidavit of the applicable Holder shall constitute such evidence) of the ownership and the loss, theft, destruction or mutilation of any certificate evidencing Preferred Stock, and in the case of any such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Company, or, in the case of any such mutilation upon surrender of such certificate, the Company shall (at its expense) execute and deliver in lieu of such certificate a new certificate of like kind representing the Preferred Stock represented by such lost, stolen, destroyed or mutilated certificate and dated the date of such lost, stolen, destroyed or mutilated certificate.

(e) Unless otherwise agreed to by the Company and the applicable Holder, each certificate representing Series A Preferred Stock shall bear a restrictive legend in substantially the form attached hereto as Annex I and shall be subject to the restrictions set forth therein. In addition, such certificate may have notations, additional legends or endorsements required by law, exchange rules or agreements to which the Company and any Holder (in its capacity as a Holder) is subject, if any.

SECTION 2.3 Right of First Refusal.

(a) Subject to the terms of Section 2.2, each Holder hereby unconditionally and irrevocably grants to the Major Holders a Right of First Refusal to purchase all or any portion of Transfer Stock that such Holder may propose to transfer in a Proposed Holder Transfer, at the same price and on the same terms and conditions as those offered to the Prospective Transferee.

(b) Each Holder proposing to make a Proposed Holder Transfer must deliver a Proposed Transfer Notice to each Major Holder not later than thirty (30) days prior to the consummation of such Proposed Holder Transfer. Such Proposed Transfer Notice shall contain the material terms and conditions (including price and form of consideration) of the Proposed Holder Transfer, the identity of the Prospective Transferee and the intended date of the Proposed Holder Transfer. To exercise its Right of First Refusal under this Article II, the Exercising Major Holder must deliver a Major Holder Notice to the selling Holder and other Major Holders within fifteen (15) days after delivery of the Proposed Transfer Notice specifying the number of shares of Transfer Stock to be purchased by such Exercising Major Holder.

(c) If any Holder becomes obligated to sell any Transfer Stock to any Major Holder under this Agreement and fails to deliver such Transfer Stock in accordance with the terms of this Agreement, the Major Holder may, at its option, in addition to all other remedies it may have, send to such Holder the purchase price for such Transfer Stock as is herein specified and transfer to the name of the Major Holder (or request that the Company effect such transfer in the name of a Major Holder) on the Company’s books any certificates, instruments, or book entry representing the Transfer Stock to be sold.

SECTION 4.6 Specific Performance; Remedies. The parties hereby expressly recognize and acknowledge that immediate, extensive and irreparable damage would result, no adequate remedy at law would exist, and damages would be difficult to determine in the event that any provision of this Agreement is not performed in accordance with its specific terms or otherwise breached. Therefore, in addition to, and not in limitation of, any other remedy available to any party hereto, a party under this Agreement will be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy and without bond or other security being required. Such remedies, and any and all other remedies provided for in this Agreement, will, however, be cumulative in nature and not exclusive and will be in addition to any other remedies whatsoever which any party may otherwise have. Each of the parties hereto hereby acknowledges and agrees that it may be difficult to prove damages with reasonable certainty, that it may be difficult to procure suitable substitute performance, and that injunctive relief and/or specific performance will not cause an undue hardship to the parties. Each of the parties hereto hereby further acknowledges that the existence of any other remedy contemplated by this Agreement does not diminish the availability of specific performance of the obligations hereunder or any other injunctive relief. Each party hereto hereby further agrees that in the event of any action by any other party for specific performance or injunctive relief, it will not assert that a remedy at law or other remedy would be adequate or that specific performance or injunctive relief in respect of such breach or violation should not be available on the grounds that money damages are adequate or any other grounds.
