WHEREAS, the Purchaser desires to purchase from the Company, and the Company desires to sell to Purchaser, shares of the Company's common stock, par value $0.001 ("COMMON STOCK"), on the terms set forth herein; WHEREAS, Purchaser has provided a loan to the Company in the original principal amount of $2,000,000, as evidenced by that certain Convertible Promissory Note, dated September 10, 2009 (the "PROMISSORY NOTE"); and WHEREAS, the Company is offering the Common Stock pursuant to Rule 506 of Regulation D promulgated under the Securities Act of 1933, as amended (the "SECURITIES ACT"). NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 1. SALE OF SHARES. 1.1 PURCHASE AND SALE OF SHARES. The Company hereby agrees to issue to Quercus (i) sixteen million two hundred fifty thousand (16,250,000) shares of Common Stock at a price of $0.08 per share (the "SHARE PRICE"). The shares of Common Stock to be sold by the Company hereunder shall be purchased by Quercus in the following amounts and at the following times (notwithstanding the foregoing, Quercus shall have the option, on each funding date beginning December 21, 2009, to cancel any or all of the funding): DATE NUMBER OF SHARES OF COMMON STOCK ---- -------------------------------- December 14, 2009 5,000,000 December 21, 2009 3,750,000 December 28, 2009 3,750,000 January 4, 2010 3,750,000 1.2 CONVERSION OF PROMISSORY NOTE. The Company and Quercus hereby agree that all amounts due and payable under the terms of the Promissory Note are hereby converted into shares of the Company's Common Stock as of the date of this Agreement at the Share Price and that, upon receipt by Quercus of a certificate evidencing such shares of Common Stock in accordance with the terms of this Section 1.3, the Promissory Note will be deemed paid in full. Notwithstanding the foregoing, if the Company conducts a Stock Sale at any time prior to January 1, 2011 at an effective price per share less than the Share Price, then Quercus will be entitled to such additional shares of Common Stock in connection with the conversion of the Promissory Note as determined in accordance with the provisions of Section 1.3 hereof. B-1 1.3 PRICE ADJUSTMENT. Notwithstanding the provisions of Section 1.1 and 1.2 above, if the Company, at any time prior to January 1, 2011 shall sell any equity security or any security exercisable for or convertible into an equity security (a "STOCK SALE") , then Quercus shall have the right, at its option, to receive additional securities or to exchange the securities purchased hereunder so that Quercus receives in connection with the Stock Sale the same securities (and any other property) as Quercus would have received had Quercus (a) participated in the Stock Sale instead of purchasing shares as described in Section 1.1., and (b) converted all amounts due and payable under the Promissory Note described in Section 1.2 instead of converting the Promissory Note under Section 1.2. For clarity, in such circumstance, no amount would be attributed to interest that would have been due under the Promissory Note after the date hereof. The Company shall notify Quercus in writing, no later than the trading day following the Stock Sale, indicating therein the applicable issuance price (such notice, the "DILUTIVE ISSUANCE NOTICE"). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 1.2, upon the occurrence of a Dilutive Issuance, after the date of such Dilutive Issuance, Quercus is entitled to receive a number of shares of Common Stock based upon the Base Share Price regardless of whether the Company accurately refers to the Base Share Price in a Dilutive Issuance Notice. 1.4 THE CLOSING. The sale and purchase of the Common Stock shall take place at the offices of Salvo Landau Gruen & Rogers, 510 Township Line Road, Suite 150, Blue Bell, Pennsylvania 19422, or at such other location as the Company and Quercus mutually agree, on the dates set forth in Section 1.1 (each, a "CLOSING"). At each Closing, the Company shall deliver to Quercus a certificate representing the Common Stock (the " CERTIFICATE") in the form set forth on Exhibit "A," hereto, against delivery to the Company of a check or wire transfer in the amount of the Share Price. The obligation of Quercus to consummate the purchase at the Closing is subject to the performance by the Company of the truth and accuracy of the representations and warranties of the Company in Section 2 below. 2. REPRESENTATIONS AND WARRANTIES OF COMPANY. The Company hereby represents and warrants to Quercus that: 2.1 ORGANIZATION, GOOD STANDING AND QUALIFICATION.

REPRESENTATIONS AND WARRANTIES OF QUERCUS. Quercus hereby represents and warrants to, and agrees with, the Company that: 3.1 RESTRICTED SECURITIES.

In addition to all other sums due hereunder or provided for in this Agreement, the Company agrees to indemnify and hold harmless the Purchaser and its respective "Affiliates" (as defined in Rule 12b-2 of the General Rules and Regulations under the Exchange Act) and their respective officers, directors, agents, representatives, employees, subsidiaries, partners and controlling persons (each, an "INDEMNIFIED PARTY") from and against any and all losses, claims, damages, expenses (including reasonable fees, disbursements and other charges of counsel) or other liabilities ("LIABILITIES") resulting from any breach of any covenant, agreement, representation or warranty of the Company in this Agreement; provided, however, that the Company shall not be liable under this Section 5.1: (a) for any amount paid in settlement of claims without the Company's consent (which consent shall not be unreasonably withheld) or (b) to the extent that it is finally judicially determined that such Liabilities resulted primarily from the willful misconduct or bad faith of such indemnified party; provided, further, that if and to the extent that such indemnification is held, by final judicial determination to be unenforceable, in whole or in part, for any reason, the Company shall make the maximum contribution to the payment and satisfaction of such indemnified Liability. In connection with the obligation of the Company B-7 to indemnify for expenses as set forth above, the Company further agrees to reimburse each indemnified party for all such expenses (including reasonable fees, disbursements and other charges of counsel) as they are incurred by such indemnified party; provided, however, that if an indemnified party is reimbursed hereunder for any expenses, such reimbursement of expenses shall be refunded to the extent it is finally judicially determined that the Liabilities in question resulted primarily from the willful misconduct or bad faith of such indemnified party. 5.2 NOTIFICATION; PROCEDURE. Each indemnified party under Section 5.1 will, promptly after the receipt of notice of the commencement of any action or other proceeding against such indemnified party in respect of which indemnity may be sought from the Company under Section 5.1, notify the Company in writing of the commencement thereof. The omission of any indemnified party so to notify the Company of any such action shall not relieve the Company from any liability which it may have to such indemnified party (i) other than pursuant to Section 5.1 or (ii) under Section 5.1 unless, and only to the extent that, such omission results in the Company's forfeiture of substantive rights or defenses. In case any such action or other proceeding shall be brought against any indemnified party and it shall notify the Company of the commencement thereof, the Company shall be entitled to participate therein and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that any indemnified party may, at its own expense, retain separate counsel to participate in such defense. Notwithstanding the foregoing, in any action or proceeding in which both the Company and an indemnified party is, or is reasonably likely to become, a party, such indemnified party shall have the right to employ separate counsel at the Company's expense and to control its own defense of such action or proceeding if, in the reasonable opinion of counsel to such indemnified party, (a) there are or may be legal defenses available to such indemnified party or to other indemnified parties that are different from or additional to those available to the Company or (b) any conflict or potential conflict exists between the Company and such indemnified party that would make such separate representation advisable; provided, however, that in no event shall the Company be required to pay fees and expenses under this sentence of Section 5.1 for more than one firm of attorneys in any jurisdiction in any one legal action or group of related legal actions. The Company agrees that the Company will not, without the prior written consent of the Purchaser, settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated hereby (if any indemnified party is a party thereto or has been actually threatened to be made a party thereto) unless such settlement, compromise or consent includes an unconditional release of the Purchaser and each other indemnified party from all liability arising or that may arise out of such claim, action or proceeding. No such settlement shall impose any restriction on the future conduct of any indemnified party without such party's consent, which may be withheld in such party's discretion. The rights accorded to indemnified parties hereunder shall be in addition to any rights that any indemnified party may have at common law, by separate agreement or otherwise. 6.

The invalidity of any portion hereof shall not affect the validity, force, or effect of the remaining portions hereof. If it is ever held that any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, the parties agree that a court of competent jurisdiction may enforce such restriction to the maximum extent permitted by law against those for whom it may be enforceable, and each party hereby consents and agrees that such scope may be judicially modified accordingly in any proceeding brought to enforce such restriction. 6.5 FURTHER ASSURANCES.
