ARTICLE VI DRAW DOWN TERMS; CALL OPTION SECTION 6.1 Draw Down Terms. Subject to the satisfaction of the conditions set forth in this Agreement and subject to Section 6.3 below, the parties agree as follows: (a) The Company, may, in its sole discretion, issue a Draw Down Notice with respect to a Draw Down during each Draw Down Pricing Period of up to (i) $1,500,000 if the Threshold Price is equal to or greater than $1.00 but less than $2.00, (ii) $2,500,000 if the Threshold Price is equal to or greater than $2.00 but less than $3.00 and (iii) $5,000,000 if the Threshold Price is equal to or greater than $3.00 but less than $4.00 and up to an additional $2,000,000 for every $1.00 increase in the Threshold Price above $3.00 for a maximum Draw Down Amount during each Draw Down Pricing Period of up to $35,000,000; provided, however, that the Company may, in its sole discretion, issue a Draw Down Notice with respect to any Draw Down Amount at any Threshold Price or any Draw Down Discount Percentage pursuant to terms mutually agreed upon by the Purchaser and the Company, which Draw Down the Purchaser will be obligated to accept. Prior to issuing any Draw Down Notice, the Company -19- 23 shall have Shares registered under the Registration Statement which are valued in a dollar amount equal to or in excess of the Draw Down Amount. (b) The number of Shares to be issued in connection with each Draw Down shall be equal to the sum of the quotients (for each Trading Day of the Draw Down Pricing Period for which the VWAP equals or exceeds the Threshold Price) of (x) 1/18th (or such other fraction based on the length of the Draw Down Pricing Period) of the Draw Down Amount divided by (y) the applicable Draw Down Discount Percentage (or such other percentage mutually agreed upon by the parties) multiplied by the VWAP of the Common Stock for such Trading Day. (c) Only one Draw Down shall be allowed in each Draw Down Pricing Period. (d) The number of Shares purchased by the Purchaser with respect to each Draw Down shall be determined on a daily basis during each Draw Down Pricing Period and settled on the second business day following the end of each Draw Down Pricing Period (the "Settlement Date"). (e) There shall be a minimum of five (5) Trading Days between Draw Downs, unless otherwise mutually agreed upon between the Purchaser and the Company. (f) There shall be a maximum of twenty four (24) monthly Draw Downs during the term of this Agreement. (g) Each Draw Down will expire immediately after the last Trading Day of each Draw Down Pricing Period. (h) If the VWAP on a given Trading Day in a Draw Down Pricing Period is less than the Threshold Price, then the total amount of the Draw Down for the relevant Draw Down Pricing Period will be reduced by 1/18th (or such other fraction based on the length of the Draw Down Pricing Period). At no time shall the Threshold Price be set below $1.00, unless mutually agreed upon by the Company and the Purchaser. If trading in the Company's Common Stock is suspended for any reason for more than three (3) hours in any Trading Day, at the Purchaser's option, the price of the Common Stock shall be deemed to be below the Threshold Price for that Trading Day and the Draw Down for the relevant Draw Down Pricing Period shall be reduced by 1/18th (or such other fraction based on the length of the Draw Down Pricing Period). Notwithstanding anything in the foregoing to the contrary, for each Trading Day during the Draw Down Pricing Period that the VWAP is less than the Threshold Price or is deemed to be below the Threshold Price pursuant to the immediately preceding sentence, the Purchaser may elect in its sole discretion to purchase Shares at a price equal to the Threshold Price multiplied by the Draw Down Discount Percentage at the end of such Draw Down Pricing Period. The Purchaser will inform the Company via facsimile transmission no later than 8:00 p.m. (New York time) on the last Trading Day of such Draw Down Pricing Period as to the number of Shares, if any, the Purchaser chooses to purchase under such circumstances set forth in this Section 6.1(h). -20- 24 (i) The Company must inform the Purchaser via facsimile transmission as to the Draw Down Amount the Company wishes to exercise before commencement of trading on the first Trading Day of the Draw Down Pricing Period covered by such notice (the "Draw Down Notice"), substantially in the form attached hereto as Exhibit D. In addition to the Draw Down Amount, the Company shall set the Threshold Price with each Draw Down Notice and shall designate the first Trading Day of the Draw Down Pricing Period. Notwithstanding anything in the foregoing to the contrary, if the Company wishes the date of the Draw Down Notice to be the first day of the Draw Down Pricing Period, the Draw Down Notice must be delivered to the Purchaser and receipt of such Draw Down Notice confirmed by the Purchaser prior to the commencement of trading on the date of such Draw Down Notice. (j) On each Settlement Date, the Company shall deliver the Shares purchased by the Purchaser to the Purchaser or to The Depositary Trust Company ("DTC") on the Purchaser's behalf via the Deposit Withdrawal Agent Commission system ("DWAC"), and upon receipt of the Shares, the Purchaser shall cause payment therefor to be made to the account designated by the Company by wire transfer of immediately available funds provided that the Shares are received no later than 1:00 p.m., New York time, or next day available funds if the Shares are received thereafter. (k) If during any Draw Down Pricing Period the Company shall enter into an Other Financing (other than shares of Common Stock issued under this Agreement or pursuant to a Permitted Transaction), the Purchaser may in its sole discretion (i) purchase the Draw Down Amount of shares of Common Stock and/or exercise Call Options granted during such Draw Down Pricing Period on the terms at which the Company issued shares of Common Stock in the Other Financing during such Draw Down Pricing Period, net of any third party's discount and fees, (ii) purchase the Draw Down Amount of shares of Common Stock and/or exercise Call Options granted during such Draw Down Pricing Period at the applicable Draw Down Discount Percentage times the VWAP for such Draw Down Pricing Period, or (iii) elect not to purchase any Shares during such Draw Down Pricing Period. The Purchaser shall notify the Company of its election on the business day preceding the Settlement Date. (l) If on the Settlement Date, the Company fails to deliver the Shares to be purchased by the Purchaser, and such failure continues for ten (10) Trading Days, the Company shall pay, in cash, as liquidated damages and not as a penalty to the Purchaser an amount equal to two percent (2%) of the Draw Down Amount for the initial thirty (30) days and each additional thirty (30) day period thereafter until such failure has been cured, which shall be pro rated for such periods less than thirty (30) days (the "Periodic Amount"). Cash payments to be made pursuant to this clause (1) shall be due and payable immediately upon demand in immediately available cash funds. (m) If during any Draw Down Pricing Period the Company reasonably believes an event may occur which would require the suspension of the Registration Statement, the Company shall notify the Purchaser before commencement of trading on any Trading Day (a "Section 6.1(m) Notice") and reduce the number of Trading Days in such Draw Down Pricing Period. The last Trading Day of such Draw Down Pricing Period shall be the Trading Day preceding the receipt of the Section 6.1(m) Notice; provided, however, that if the Company delivers the Section 6.1(m) Notice during trading hours on a Trading Day, then the last Trading -21- 25 Day of such Draw Down Pricing Period shall be the Trading Day on which the Section 6.1(m) Notice was received by the Purchaser. The Purchaser will purchase the Truncated Draw Down Allocation for each of the Trading Days prior to receipt of the Section 6.1(m) Notice, for an aggregate purchase price determined in accordance with clauses (b) and (i) of this Section 6.1. In addition, the Purchaser may, at its option, elect to purchase Shares in an additional dollar amount equal to the product of the Draw Down Amount Requested, first multiplied by (x) a fraction, the numerator of which equals one (1) and the denominator of which equals eighteen (18) or such other number of Trading Days in such Draw Down Pricing Period as the parties may have mutually agreed upon with respect to such Draw Down Pricing Period (eighteen or such other mutually agreed upon number being referred to herein as the "Trading Day Number"), and next multiplied by (y) that number that is equal to the Trading Day Number minus the number of Trading Days in the reduced Draw Down Pricing Period. The price per share for such additional dollar amount shall equal (i) the aggregate total of Truncated Draw Down Allocation Amounts during the reduced Draw Down Pricing Period divided by (ii) the number of Shares to be purchased during such reduced Draw Down Pricing Period. Upon receipt of the Section 6.1(m) Notice, the Purchaser may (x) elect to purchase the Common Stock at the Threshold Price for any Trading Day that the VWAP was below the Threshold Price during the reduced Draw Down Pricing Period in accordance with Section 6.1(i) hereof, (y) elect to purchase the Common Stock in the additional amount as set forth in the preceding paragraph of this Section 6.1(m), and (z) elect to exercise any unexercised Call Options (for a Call Option Amount not to exceed $1,000,000) by issuing a Call Option Notice to the Company, in each such case, no later than 10:00 a.m. (New York time) on the first Trading Day after the end of the reduced Draw Down Pricing Period. The exercise price of the Call Option shall be based on the VWAP on the last Trading Day of the reduced Draw Down Pricing Period (in lieu of the VWAP as specified in clause (A) of Section 6.2(b) hereof) and otherwise determined in accordance with Section 6.2(b) hereof. The Settlement Date for the Truncated Draw Down Amount exercised during an effected Draw Down Pricing Period shall be the second Trading Day after receipt of the Section 6.1(m) Notice. SECTION 6.2 Purchaser's Call Option. Subject to the satisfaction of the conditions set forth in this Agreement and subject to Section 6.3 below, the parties agree as follows: (a) During each Draw Down Pricing Period, the Company at its sole discretion may grant to the Purchaser the right to exercise multiple call options of up to the applicable Draw Down Amount (a "Call Option"). The amount of the Call Option shall be set forth in the Draw Down Notice. For each Trading Day during a Draw Down Pricing Period, the Purchaser may exercise a Call Option by providing notice to the Company of the exercise of a Call Option (the "Call Option Notice"), substantially in the form attached hereto as Exhibit E. -22- 26 (b) The number of shares of Common Stock to be issued in connection with each Call Option shall equal the quotient of (i) the amount of the Call Option exercised and (ii) the product of the applicable Draw Down Discount Percentage and the greater of (A) the VWAP for the Common Stock on the day the Purchaser issues its Call Option Notice and (B) the Threshold Price. (c) Each Call Option exercised shall be settled on the applicable Settlement Date. (d) The Threshold Price designated by the Company in its Draw Down Notice shall apply to each Call Option. (e) For each Call Option that the Purchaser exercises pursuant to this Section 6.2, the Purchaser must issue via facsimile a Call Option Notice to the Company no later than 8:00 p.m. (New York time) on the day such Call Option is exercised. If the Purchaser does not exercise a Call Option by 8:00 p.m. (New York time) on the last day of the applicable Draw Down Pricing Period, the Purchaser's Call Options with respect to that Draw Down Pricing Period shall terminate. SECTION 6.3 Aggregate Limit. Notwithstanding anything to the contrary herein, in no event may the Company issue a Draw Down Notice or grant a Call Option to the extent that the sale of shares of Common Stock pursuant thereto and pursuant to all prior Draw Down Notices or Call Options issued hereunder would cause the Company to sell or the Purchaser to purchase shares of Common Stock which in the aggregate are in a dollar amount in excess of the Aggregate Limit. If the Company issues a Draw Down Notice or Call Option that otherwise would permit the Purchaser to purchase shares of Common Stock which would cause the aggregate purchases by Purchaser hereunder to exceed the Aggregate Limit, such Draw Down Notice or Call Option shall be void ab initio to the extent of the amount by which the value of the shares of Common Stock otherwise issuable pursuant to such Draw Down Notice or Call Option together with the value of all other Common Stock purchased by the Purchaser pursuant hereto would exceed the Aggregate Limit. ARTICLE VII TERMINATION SECTION 7.1 Termination by Mutual Consent. The term of this Agreement shall expire on the earlier of (i) twenty eight (28) months from the date of execution of this Agreement, (ii) the date that the entire dollar amount of the shares of Common Stock registered under the Registration Statement have been issued and sold and (iii) the date that the Purchaser has purchased in the aggregate $60,800,000 pursuant to all Draw Downs issued and Call Options granted and exercised (the "Investment Period"). This Agreement may be terminated at any time by mutual consent of the parties. SECTION 7.2 Other Termination. The Company shall inform the Purchaser, and the Purchaser shall have the right to terminate this Agreement within the subsequent thirty (30) days (the "Event Period"), if (x) the Company enters into an Other Financing (other than a -23- 27 Permitted Transaction or an underwritten public offering) which provides for (i) the issuance of Common Stock or securities convertible, exercisable or exchangeable into Common Stock at a discount to the then current market price of the Common Stock (except for Other Financings of up to an aggregate of $80,000,000, provided that such issuance of Common Stock or such conversion, exercise or exchange into Common Stock is at a fixed price (the "Permitted Discounted Financing")), (ii) a mechanism for the reset of the purchase price of the Common Stock to below the then current market price of the Common Stock, or (iii) the issuance of Common Stock with warrants, which have an exercise price such that together with the price of the Common Stock would result in the issuance of shares of Common Stock at a per share price below the then current market price of the Common Stock, or (y) an event resulting in a Material Adverse Effect except continued losses from operations or Material Change in Ownership has occurred. The Purchaser may terminate this Agreement upon one (1) day's notice during the Event Period. SECTION 7.3 Effect of Termination. In the event of termination by the Company or the Purchaser, written notice thereof shall forthwith be given to the other party and the transactions contemplated by this Agreement shall be terminated without further action by either party. If this Agreement is terminated as provided in Section 7.1 or 7.2 herein, this Agreement shall become void and of no further force and effect, except as provided in Section 9.9 hereof. Nothing in this Section 7.3 shall be deemed to release the Company or the Purchaser from any liability for any breach under this Agreement, or to impair the rights of the Company and the Purchaser to compel specific performance by the other party of its obligations under this Agreement. ARTICLE VIII INDEMNIFICATION SECTION 8.1 General Indemnity. (a) Indemnification by the Company. The Company will indemnify and hold harmless each of the Purchaser and Carlin, each of their directors, fund managers and officers, and each person, if any, who controls the Purchaser or Carlin within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act from and against any losses, claims, damages, liabilities and expenses (including reasonable costs of defense and investigation and all reasonable attorneys' fees) to which the Purchaser and Carlin, each of their directors, fund managers and officers, and each person, if any, who controls the Purchaser or Carlin may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities and expenses (or actions in respect thereof) arise out of or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained, or incorporated by reference, in the Registration Statement relating to Common Stock being sold to the Purchaser (including any prospectus supplement filed in connection with the transactions contemplated hereunder (the "Prospectus Supplement") which are a part of it), or any amendment or supplement to it, or (ii) the omission or alleged omission to state in that Registration Statement or any document incorporated by reference in the Registration Statement, a material fact required to be stated therein or necessary to make the statements therein not misleading, provided that the Company shall not be liable under this Section 8.1(a) to the extent that a court of competent jurisdiction shall have determined by a final judgment (with no appeals available) that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act, -24- 28 undertaken or omitted to be taken by the Purchaser or Carlin or such person through its bad faith or willful misconduct; provided, however, that the foregoing indemnity shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Purchaser or Carlin expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and provided, further, that with respect to the Prospectus, the foregoing indemnity shall not inure to the benefit of the Purchaser or Carlin or any such person from whom the person asserting any loss, claim, damage, liability or expense purchased Common Stock, if copies of the Prospectus were timely delivered to the Purchaser pursuant hereto and a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of the Purchaser or Carlin or any such person to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Common Stock to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or expense. The Company will reimburse the Purchaser, Carlin and each such controlling person promptly upon demand for any legal or other costs or expenses reasonably incurred by the Purchaser, Carlin or such controlling person in investigating, defending against, or preparing to defend against any such claim, action, suit or proceeding, except that the Company will not be liable to the extent a claim or action which results in a loss, claim, damage, liability or expense arises out of, or is based upon, an untrue statement, alleged untrue statement, omission or alleged omission, included in any Registration Statement, Prospectus or Prospectus Supplement or any amendment or supplement to the thereto in reliance upon, and in conformity with, written information furnished by either the Purchaser or Carlin to the Company for inclusion in the Registration Statement, Prospectus or Prospectus Supplement. (b) Indemnification by the Purchaser. The Purchaser will indemnify and hold harmless the Company, each of its directors and officers, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act from and against any expenses (including reasonable costs of defense and investigation and all attorneys' fees) to which the Company and each director, officer and person, if any, who controls the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages, liabilities and expenses (or actions in respect thereof) arise out of or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any Prospectus or Prospectus Supplement or any amendment or supplement to it or (ii) the omission or alleged omission to state in the Registration Statement or any Prospectus or Prospectus Supplement or any amendment or supplement to it a material fact required to be stated therein or necessary to make the statements therein not misleading, to the extent, but only to the extent, the untrue statement, alleged untrue statement, omission or alleged omission was made in reliance upon, and in conformity with, written information furnished by the Purchaser to the Company for inclusion in the Registration Statement, the Prospectus or Prospectus Supplement or an amendment or supplement thereto, and the Purchaser will reimburse the Company and each such director, officer or controlling person promptly upon demand for any legal or other costs or expenses reasonably incurred by -25- 29 the Company or the other person in investigating, defending against, or preparing to defend against any such claim, action, suit or proceeding. SECTION 8.2 Indemnification Procedures. Promptly after a person receives notice of a claim or the commencement of an action for which the person intends to seek indemnification under paragraph (a) or (b) of Section 8.1, the person will notify the indemnifying party in writing of the claim or commencement of the action, suit or proceeding, but failure to notify the indemnifying party will not relieve the indemnifying party from liability under paragraph (a) or (b) of Section 8.1, except to the extent it has been materially prejudiced by the failure to give notice. The indemnifying party will be entitled to participate in the defense of any claim, action, suit or proceeding as to which indemnification is being sought, and if the indemnifying party acknowledges in writing the obligation to indemnify the party against whom the claim or action is brought, the indemnifying party may (but will not be required to) assume the defense against the claim, action, suit or proceeding with counsel satisfactory to it. After an indemnifying party notifies an indemnified party that the indemnifying party wishes to assume the defense of a claim, action, suit or proceeding the indemnifying party will not be liable for any legal or other expenses incurred by the indemnified party in connection with the defense against the claim, action, suit or proceeding except that if, in the opinion of counsel to the indemnifying party, one or more of the indemnified parties should be separately represented in connection with a claim, action, suit or proceeding the indemnifying party will pay the reasonable fees and expenses of one separate counsel for the indemnified parties. Each indemnified party, as a condition to receiving indemnification as provided in Paragraph (a) or (b) or Section 8.1, will cooperate in all reasonable respects with the indemnifying party in the defense of any action or claim as to which indemnification is sought. No indemnifying party will be liable for any settlement of any action effected without its prior written consent. No indemnifying party will, without the prior written consent of the indemnified party, effect any settlement of a pending or threatened action with respect to which an indemnified party is, or is informed that it may be, made a party and for which it would be entitled to indemnification, unless the settlement includes an unconditional release of the indemnified party from all liability and claims which are the subject matter of the pending or threatened action. If for any reason the indemnification provided for in this Agreement is not available to, or is not sufficient to hold harmless, an indemnified party in respect of any loss or liability referred to in paragraph (a) or (b) of Section 8.1, each indemnifying party will, in lieu of indemnifying the indemnified party, contribute to the amount paid or payable by the indemnified party as a result of the loss or liability, (i) in the proportion which is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and by the indemnified party on the other from the sale of stock which is the subject of the claim, action, suit or proceeding which resulted in the loss or liability or (ii) if that allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits of the sale of stock, but also the relative fault of the indemnifying party and the indemnified party with respect to the statements or omissions which are the subject of the claim, action, suit or proceeding that resulted in the loss or liability, as well as any other relevant equitable considerations. -26- 30 ARTICLE IX MISCELLANEOUS SECTION 9.1 Fees and Expenses. Each party shall bear its own fees and expenses related to the transactions contemplated by this Agreement; provided, however, that the Company shall pay, at the Closing, all reasonable attorneys fees and expenses (exclusive of disbursements and out-of-pocket expenses) incurred by the Purchaser of up to $25,000 in connection with the preparation, negotiation, execution and delivery of this Agreement. In addition, the Company shall pay all reasonable fees and expenses incurred by the Purchaser in connection with any amendments, modifications or waivers of this Agreement or incurred in connection with the enforcement of this Agreement, including, without limitation, all reasonable attorneys' fees and expenses.

(b) Each of the Company and the Purchaser (i) hereby irrevocably submits to the jurisdiction of the United States District Court and other courts of the United States sitting in the State of New York for the purposes of any suit, action or proceeding arising out of or relating to this Agreement and (ii) hereby waives, and agrees not to assert in any such suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such court, that the suit, action or proceeding is brought in an inconvenient forum or that the venue of the suit, action or proceeding is improper. Each of the Company and the Purchaser consents to process being served in any such suit, action or proceeding by mailing a copy thereof 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.
