If trading in the Company’s Common Stock is suspended for any reason for more than three (3) consecutive or non-consecutive hours during any Trading Day during a Draw Down Pricing Period, such Trading Day shall not be used in calculating the number of Shares to be issued in connection with such Draw Down, and the Draw

3

Down Amount in respect of such Draw Down Pricing Period shall be reduced by one eighth (1/8th) of the initial Draw Down Amount specified in the Draw Down Notice.

1.5 Section 6.7 of the Purchase Agreement is hereby amended and restated to read in its entirety as follows:

6.7 Prohibited Transactions. Except as set forth on Schedule 6.7 of the Disclosure Schedule, during the term of this Agreement, the Company shall not enter into any Prohibited Transaction without the prior written consent of the Investor, which consent may be withheld at the sole discretion of the Investor. For the purposes of this Agreement, the term “Prohibited Transaction” shall refer to the issuance by the Company of any “future priced securities,” which shall mean the issuance of shares of Common Stock or securities of any type whatsoever that are, or may become, convertible or exchangeable into shares of Common Stock where the purchase, conversion or exchange price for such Common Stock is determined using any floating discount or other post-issuance adjustable discount to the market price of Common Stock, including, without limitation, pursuant to any equity line or other financing that is substantially similar to the financing provided for under this Agreement; provided, however, that a Prohibited Transaction shall not include any future issuance by the Company of a convertible security (“Convertible Security”) that contains provisions that adjust the purchase, conversion or exchange price of such Convertible Security (i) in the event of stock splits, dividends, distributions or similar events, (ii) in the event of or in connection with transactions customarily constituting or that may constitute a change in control of, or a fundamental change in, the Company, including pursuant to “make-whole” provisions and the like, or (iii) pursuant to anti-dilution provisions.

1.6 Section 6.11 of the Purchase Agreement is hereby amended and restated to read in its entirety as follows:

6.11 Amendments to the Registration Statement. After the Registration Statement has been declared effective by the Commission, the Company shall not (a) file any amendment to the Registration Statement or make any amendment or supplement to the Prospectus of which the Investor shall not have been previously or be simultaneously advised; provided, however, that the Company shall, to the extent it deems advisable, and without the prior consent of or notice to Investor, supplement the Prospectus within one Trading Day following the Settlement Date for each Draw Down solely to reflect the issuance of Shares with respect to such Draw Down, and provided further, however, that the Company need not so advise the Investor regarding any amendment or supplement the purpose of which is to update the Registration Statement and the Prospectus to include information the Company has previously or simultaneously filed with the Commission pursuant to Section 13 or 15(d) under the Exchange Act; and (b) so long as, in the reasonable opinion of counsel for the Investor, a Prospectus is required to be delivered in

4

connection with sales of the Shares by the Investor, if the Company files any information, documents or reports that are incorporated by reference in the Registration Statement pursuant to the Exchange Act, the Company shall, if requested in writing by the Investor, deliver a copy of such information, documents or reports to the Investor promptly following such filing to the extent such information, documents or reports are not available on the Commission’s EDGAR filing system.

2. Amendments to the Registration Rights Agreement.

2.1 Sections 1.1(a) through 1.1(e) of the Registration Rights Agreement are hereby amended and restated to read in their entirety as follows:

(a) Filing of the Registration Statement. Upon the terms and subject to the conditions set forth in this Agreement, the Company shall file with the Commission on or before December 15, 2009 (or such other date as agreed in writing between the Company and the Investor) a registration statement under the Securities Act for the registration of the resale by the Investor of the Registrable Securities, which such registration statement shall initially be on Form S-1 under the Securities Act or such other form as deemed appropriate by counsel to the Company for the registration of the resale by the Investor of the Registrable Securities (such registration statement, the “Registration Statement”).

(b) Effectiveness of the Registration Statement; Conversion to Form S-3. The Company shall use commercially reasonable efforts (i) to have the Registration Statement declared effective by the Commission as soon as reasonably practicable, but in any event no later than April 30, 2010 (the “Effectiveness Deadline”) and (ii) to ensure that the Registration Statement remains in effect throughout the term of this Agreement as set forth in Section 4.2, subject to the terms and conditions of this Agreement. In the event that the Registration Statement, as initially declared effective by the Commission, is a registration statement on Form S-1 under the Securities Act, then the Company shall use commercially reasonable efforts to convert such Registration Statement to a registration statement on Form S-3 under the Securities Act as soon as reasonably practicable following the Form S-3 Eligibility Date; provided, however, that in no event shall the Company be obligated to convert such Registration Statement as aforesaid prior to the Effectiveness Deadline. For purposes of this Agreement, the “Form S-3 Eligibility Date” shall be the date that the Company shall, upon advice of counsel to the Company, become eligible to use Form S-3 for the registration of the resale by the Investor of the Registrable Securities; provided, however, that the Form S-3 Eligibility Date shall in all cases be subject to any determinations by the Commission with respect thereto.

(c) Regulatory Disapproval. The contemplated effective date for the Registration Statement as described in Section 1.1(b) shall be extended without default or liquidated damages hereunder or under the Purchase Agreement (and

5

without the ability of the Investor to terminate the Purchase Agreement pursuant to Section 8.2(b) thereof) in the event that the Company’s failure to obtain the effectiveness of the Registration Statement on a timely basis results from (i) the failure of the Investor to timely provide the Company with information requested by the Company and necessary to complete the Registration Statement in accordance with the requirements of the Securities Act, or (ii) the Commission’s disapproval of the structure of the transactions contemplated by the Purchase Agreement, or (iii) a determination by the Commission (including any initial determination included in any Commission staff comment letter received by the Company with respect to the Registration Statement) that either the Company or the Investor is ineligible to rely on Rule 415 under the Securities Act with respect to (or that Rule 415 is otherwise unavailable or may not be relied upon with respect to) the registration of any or all of the Registrable Securities for resale by the Investor, or (iv) events or circumstances that are not in any way attributable to the Company. In the event of clauses (ii) and (iii) above, the parties agree to cooperate with one another in good faith to arrive at a resolution acceptable to the Commission.

(d) Failure to Maintain Effectiveness of Registration Statement. In the event the Company fails to maintain the effectiveness of the Registration Statement (or the Prospectus) throughout the period set forth in Section 4.2, other than POSAM Suspensions (as defined below) or temporary suspensions as set forth in Section 1.1(e), and the Investor holds any Registrable Securities at any time during the period of such ineffectiveness (an “Ineffective Period”), and provided that such failure to maintain effectiveness was within the reasonable control of the Company, the Company shall pay on demand to the Investor in immediately available funds into an account designated by the Investor an amount equal to the product of (i) the total number of Registrable Securities issued to the Investor under the Purchase Agreement (which, for the avoidance of doubt, shall not include any Warrant Shares) and owned by the Investor at any time during such Ineffective Period (and not otherwise sold, hypothecated or transferred) and (ii) the result, if greater than zero, obtained by subtracting the VWAP on the Trading Day immediately following the last day of such Ineffective Period from the VWAP on the Trading Day immediately preceding the day on which any such Ineffective Period began; provided, however, that (A) the foregoing payments shall not apply in respect of Registrable Securities (I) that are otherwise freely tradable by the Investor, including pursuant to Rule 144 under the Securities Act (as such Rule may be amended from time to time, “Rule 144”) or (II) if the Company offers to repurchase from the Investor such Registrable Securities for a per share purchase price equal to the VWAP on the Trading Day immediately preceding the day on which any such Ineffective Period began and (B) unless otherwise required by any applicable federal and state securities laws, the Company shall be under no obligation to supplement the Prospectus to reflect the issuance of any Shares pursuant to a Draw Down at any time prior to the day following the Settlement Date with respect to such Shares and that the failure to

6

supplement the Prospectus prior to such time shall not be deemed a failure to maintain the effectiveness of the Registration Statement (or Prospectus) for purposes of this Agreement (including this Section 1.1(d)). For purposes of this Section 1.1(d), a “POSAM Suspension” shall mean the suspension of effectiveness of the Registration Statement as the result of the filing of a post-effective amendment to the Registration Statement (x) when required pursuant to Section 10(a)(3) under the Securities Act or Item 512(a)(1) of Regulation S-K, or (y) to convert the Registration Statement from a registration statement on Form S-1 under the Securities Act to a registration statement on Form S-3 under the Securities Act.

(e) Deferral or Suspension During a Blackout Period. Notwithstanding the provisions of Section 1.1(d), if in the good faith judgment of the Company, following consultation with legal counsel, it would be detrimental to the Company or its stockholders for the Registration Statement to be filed or for resales of Registrable Securities to be made pursuant to the Registration Statement due to (i) the existence of a material development or potential material development involving the Company that the Company would be obligated to disclose or incorporate by reference in the Registration Statement and which the Company has not disclosed, or which disclosure would be premature or otherwise inadvisable at such time or would have a Material Adverse Effect on the Company or its stockholders, or (ii) a filing of a Company-initiated registration of any class of its equity securities, which, in the good faith judgment of the Company, would adversely effect or require premature disclosure of the filing of such Company-initiated registration (notice thereof, a “Blackout Notice”), the Company shall have the right to (A) immediately defer such filing for a period of not more than sixty (60) days beyond the date by which such Registration Statement was otherwise required hereunder to be filed or (B) suspend use of such Registration Statement for a period of not more than thirty (30) days (any such deferral or suspension period, a “Blackout Period”). The Investor acknowledges that it would be seriously detrimental to the Company and its stockholders for such Registration Statement to be filed (or remain in effect) during a Blackout Period and therefore essential to defer such filing (or suspend the use thereof) during such Blackout Period and agrees to cease any disposition of the Registrable Securities during such Blackout Period. The Company may not utilize any of its rights under this Section 1.1(e) to defer the filing of a Registration Statement (or suspend its effectiveness) more than six (6) times in any twelve (12) month period. In the event that, during the applicable Blackout Damages Period (as defined below), the Company gives a Blackout Notice to the Investor and the VWAP on the Trading Day immediately preceding such Blackout Period (“Old VWAP”) is greater than the VWAP on the first Trading Day following such Blackout Period that the Investor may sell its Registrable Securities pursuant to an effective Registration Statement (“New VWAP”), then the Company shall pay to the Investor, by wire transfer of immediately available funds to an account designated by the Investor, the Blackout Amount. For the purposes of this Agreement, “Blackout Amount”

7

means a percentage equal to: (1) seventy-five percent (75%) if such Blackout Notice is delivered prior to the fifth (5th) Trading Day following such Settlement Date; (2) fifty percent (50%) if such Blackout Notice is delivered on or after the fifth (5th) Trading Day following such Settlement Date, but prior to the tenth (10th) Trading Day following such Settlement Date; (3) twenty-five percent (25%) if such Blackout Notice is delivered on or after the tenth (10th) Trading Day following such Settlement Date, but prior to the fifteenth (15th) Trading Day following such Settlement Date; and (4) zero percent (0%) thereafter (such percentage, as applicable, the “Applicable Percentage”) of: the product of (i) the number of Registrable Securities purchased by the Investor pursuant to the most recent Draw Down and actually held by the Investor immediately prior to the Blackout Period and (ii) the result, if greater than zero, obtained by subtracting the New VWAP from the Old VWAP (such product, the “Blackout Product”); provided, however, that if on the Trading Day immediately preceding such Blackout Period the Registration Statement is then a registration statement on Form S-1 under the Securities Act, then the Blackout Amount shall be calculated solely by reference to the Blackout Product and not by the Applicable Percentage of the Blackout Product. Notwithstanding anything in the foregoing to the contrary, no Blackout Amount shall be payable in respect of Registrable Securities (x) that are otherwise freely tradable by the Investor, including under Rule 144, during the Blackout Period or (y) if the Company offers to repurchase from the Investor such Registrable Securities for a per share purchase price equal to the VWAP on the Trading Day immediately preceding the day on which any such Blackout Period began. For any Blackout Period in respect of which a Blackout Amount becomes due and payable, rather than paying the Blackout Amount, the Company may at is sole discretion, issue to the Investor shares of Common Stock with an aggregate market value determined as of the first Trading Day following such Blackout Period equal to the Blackout Amount (“Blackout Shares”). For purposes of this Agreement, the “Blackout Damages Period” means, as applicable: (i) if on the Trading Day immediately preceding the applicable Blackout Period the Registration Statement is then a registration statement on Form S-3 under the Securities Act, the period beginning on any Settlement Date and ending on the fifteenth (15th) Trading Day following such Settlement Date; or (ii) if on the Trading Day immediately preceding the applicable Blackout Period the Registration Statement is then a registration statement on Form S-1 under the Securities Act, the period beginning on any Settlement Date and ending on the tenth (10^th) Trading Day following such Settlement Date.

2.2 Section 4.2 of the Registration Rights Agreement is hereby amended and restated to read in its entirety as follows:

Section 4.2 Term. The registration rights provided to the holders of Registrable Securities hereunder, and the Company’s obligation to keep the Registration Statement effective, shall terminate at the earlier of (a) such time that is one year following the termination of the Purchase Agreement, (b) such time as all Registrable Securities have been issued and have ceased to be Registrable

8

Securities, or (c) upon the consummation of an “Excluded Merger or Sale” as defined in the Warrant or an event described in the last sentence of Section 6(d) or Section 6(e) of the Warrant. Notwithstanding the foregoing, Section 1.1(d), Article III, Section 4.7, Section 4.8, Section 4.9, Section 4.10, Section 4.11 and Section 4.13 shall survive the termination of this Agreement.

3. Amendment to the Warrant. The definition of “Exercise Price” in Section 1 of the Warrant is hereby amended and restated to read in its entirety as follows:

“Exercise Price” shall mean nine dollars and twenty cents ($9.20) per Warrant Share, as the same may be adjusted from time to time pursuant to Section 6 hereof.

4. Prior Registration Statement. The Investor hereby (i) acknowledges that the Company has filed an application for withdrawal of the Prior Registration Statement pursuant to Rule 477 under the Securities Act, reaffirms its consent to the same, and acknowledges and agrees that no sales or issuances of Registrable Securities may be made thereunder, (ii) acknowledges and agrees that any and all agreements and covenants of the Company in the Purchase Agreement and the Registration Rights Agreement with respect to the Prior Registration Statement shall terminate and have no further force or effect as of the date hereof, and (iii) waives any failure by the Company to comply with the provisions of the Purchase Agreement or the Registration Rights Agreement concerning the Prior Registration Statement (including with respect to any of the Company’s actions or inactions with respect to the Prior Registration Statement).

5. Representations and Warranties. Each of the Company and the Investor (together, the “Parties” and each, a “Party”) represents and warrants as follows (which representations and warranties shall survive the execution and delivery of this Amendment Agreement until the termination of the Purchase Agreement):

5.1 The execution, delivery and performance of this Amendment Agreement by such Party and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary corporate action, and no further consent or authorization of such Party, its Board of Directors or stockholders is required (other than as contemplated by Section 6.5 of the Purchase Agreement).

5.3 Such Party’s representations and warranties set forth in the Purchase Agreement are true and correct in all material respects as though made on and as of the date hereof (except for such representations and warranties that are made as of a particular date). In

9

addition, the Investor hereby acknowledges and reaffirms its representations, warranties and covenants included in that certain Representation Letter dated May 7, 2008 (the “Investor Representation Letter”).
