Section 3.1 Draw Down Notice. During the Commitment Period, the Company may, in its sole discretion, issue a Draw Down Notice (as hereinafter defined) which shall specify the dollar amount the Company desires to raise from the Investor from the sale of Common Stock hereunder (each such capital raising transaction, a “Draw Down”), including the Minimum Obligated Amount and any Supplemental Amount.

In addition to the Draw Down Amount, each Draw Down Notice shall designate the first Trading Day of the Draw Down Pricing Period, the Threshold Price, the Supplemental Threshold Price (if any) and the allocation of Minimum Obligated Amount and Supplemental Amount (if any). Each Draw Down Notice shall be accompanied by a certificate (substantially in the form of Exhibit C hereof), signed by the Chief Executive Officer or Chief Financial Officer, dated as of the date of such Draw Down Notice.

Section 3.2 Supplemental Amount. In the event that the Company chooses to request a Supplemental Amount in connection with a Draw Down, such request shall be deemed to be an option granted by the Company to the Investor to purchase additional Shares (i.e., in addition to the Shares purchased in respect of the Minimum Obligated Amount) for an amount up to the Supplemental Amount. The Investor may exercise all or any portion of this option for any Trading Day during the Draw Down Pricing Period, and purchase Shares in respect of all or any portion of the Supplemental Amount, at a price per share equal to the Purchase Price. For any Trading Day during the applicable Draw Down Pricing Period for which the Investor exercises its option, it shall notify the Company in writing not later than 6:59 A.M. EST on the Trading Day immediately following the Trading Day for which such purchase is effectively made. Such notice to the Company, substantially in the form of Exhibit D hereof, shall specify the aggregate dollar amount for the purchase, the Purchase Price and the resulting number of Shares to be purchased in respect of the Supplemental Amount requested. Any portion of a Supplemental Amount remaining unexercised after 8:00 P.M. EST on the final Trading Day of a Draw Down Pricing Period shall automatically expire, terminate and be of no further force or effect.

Section 3.3 Number of Shares. The number of Shares to be issued in connection with each Draw Down shall be equal to the sum of the number of shares issuable for each Trading Day of the Draw Down Pricing Period. Subject to Section 3.7(b), the number of Shares issuable for a Trading Day during a Draw Down Pricing Period shall be equal to the sum of the quotients of MOA divided by PP [(MOA)/PP] plus SA divided by SAPP [(SA)/SAPP] , where MOA is equal to one eighth (1/8th) of the Minimum Obligated Amount, SA is equal to the Supplemental Amount (or portion thereof) exercised by the Investor in respect of such Trading Day, PP is equal to the Purchase Price in respect of such Trading Day and SAPP is equal to the Supplemental Amount Purchase Price in respect of such Trading Day.

- 8 - -

Section 3.4 Limitation on Draw Downs. Only one Draw Down shall be permitted for each Draw Down Pricing Period.

Section 3.5 Trading Cushion. Unless the parties agree in writing otherwise, there shall be a minimum of three (3) Trading Days between the expiration of any Draw Down Pricing Period and the beginning of the next succeeding Draw Down Pricing Period.

Section 3.6 Settlement. The number of Shares purchased by the Investor in any Draw Down shall be determined and settled on two separate dates. Shares purchased by the Investor in respect of the first four Trading Days of any Draw Down Pricing Period shall be determined and settled no later than the sixth (6th) Trading Day of such Draw Down Pricing Period. Shares purchased by the Investor in respect of the second (2nd) four (4) Trading Days of any Draw Down Pricing Period shall be determined and settled no later than the second (2nd) Trading Day after the last Trading Day of such Draw Down Pricing Period. Each date on which settlement of the purchase and sale of Shares occurs hereunder being referred to as a “Settlement Date.” The Investor shall provide the Company with delivery instructions for the Shares to be issued at each Settlement Date at least two Trading Days in advance of such Settlement Date. The number of Shares actually issued shall be rounded down to the nearest whole number of Shares.

Section 3.7 Delivery of Shares; Payment of Draw Down Amount.

(a) On each Settlement Date, the Company shall deliver the Shares purchased by the Investor to the Investor or its designee(s) via DTC’s Deposit/Withdrawal at Custodian (DWAC) system, and the Investor shall cause payment therefor to be made to the Company’s designated account by wire transfer of immediately available funds, if the Shares are received by the Investor no later than 12:00 P.M. EST, or next day available funds, if the Shares are received thereafter. Upon the written request of the Company, the Investor will cause its banker to confirm to the Company that the Investor has provided irrevocable instructions to cause payment for the Shares to be made as set forth above, upon confirmation by such banker that the Shares have been delivered through the DTC in unrestricted form.

(b) (i) for each Trading Day during a Draw Down Pricing Period on which the VWAP is less than the Threshold Price, such Trading Day shall be disregarded in calculating the number of Shares to be issued in respect of the Minimum Obligated Amount for such Draw Down, and the Draw Down Amount in respect of such Draw Down Pricing Period shall be reduced by one eighth (1/8th) of the Minimum Obligated Amount specified in the Draw Down Notice; provided, however, that the Investor may purchase Shares in respect of such Trading Day and Minimum Obligated Amount of up to one eighth (1/8th) of such Minimum Obligated Amount for a Purchase Price determined using a VWAP equal to the Threshold Price; (ii) if trading in the Company’s Common Stock is suspended for any reason for more than three (3) consecutive or non-consecutive hours during trading hours on the Principal Market on any Trading Day during a Draw Down Pricing Period, such Trading Day shall be disregarded in calculating the number of Shares to be issued in respect of the Minimum Obligated Amount for such Draw Down, and the Draw Down Amount in respect of such Draw Down Pricing Period shall be reduced by one eighth (1/8th) of the Minimum Obligated Amount specified in the Draw Down Notice; provided, however, that the Investor may purchase Shares in respect of such Trading Day and Minimum Obligated Amount of up to one eighth (1/8th) of such Minimum Obligated Amount and (iii) for each Trading Day during a Draw Down Pricing Period for which the Company has specified a Supplemental Amount, but the VWAP is less than the Supplemental Threshold Price, the Investor may purchase Shares in respect of such Supplemental Amount (or portion thereof) in consideration for payment to the Company of an amount per Share equal to the Purchase Price, determined using a VWAP equal to the Supplemental Threshold Price. For the avoidance of doubt, any Trading Day that is disregarded for the purposes of calculating the number of Shares to be issued in respect of a Minimum Obligated Amount in accordance with (i) and (ii) above shall only reduce such number of Shares by one eighth (1/8th) of the Minimum Obligated Amount, notwithstanding that such Trading Day may be so disregarded for the reasons specified in both (i) and (ii).

- 9 - -

(c) In the event that the Investor chooses to purchase Shares in respect of a Trading Day which would otherwise not be issued and sold on the basis of one of the reasons set forth in Section 3.7(b) above, the Investor shall notify the Company in writing not later than 8 A.M. EST on the Trading Day immediately following such Trading Day.

Section 3.8 Failure to Deliver Shares.

(a) If on any Settlement Date, the Company fails to take all actions within its reasonable control to cause the delivery of the Shares purchased by the Investor, and such failure is not cured within two (2) Trading Days following such Settlement Date (such period, the “Cure Period”), the Company shall pay to the Investor on demand in cash by wire transfer of immediately available funds to an account designated by the Investor, as liquidated damages for such failure and not as a penalty, an amount equal to two percent (2.0%) of the payment required to be paid by the Investor on such Settlement Date (i.e., the Draw Down Amount). If on or prior to the 70th day following the Settlement Date, the Investor shall notify the Company of the Make Whole Amount, the Company shall pay to the Investor on demand in cash by wire transfer of immediately available funds the difference, if positive, between the Make Whole Amount and the amount paid to Investor as liquidated damages pursuant to the foregoing sentence. If the Company shall fail to make timely payment of the Make Whole Amount within two (2) Trading Days following demand therefor from the Investor as herein provided, as liquidated damages for such failure and not as a penalty, in addition to the Make Whole Amount, the Company shall pay to the Investor an additional two percent (2.0%) for each 30-day period (prorated for such periods less than 30 days) following the date of such demand from the Investor, until the Make Whole Amount shall have been paid in full to the Investor. As used herein, the Make Whole Amount shall be an amount equal to the sum of (i) the Draw Down Amount actually paid by the Investor in respect of such Shares plus (ii) an amount equal to the actual loss suffered by the Investor in respect of sales to subsequent purchasers, pursuant to transactions entered into before the Settlement Date, of the Shares that were required to be delivered by the Company on such Settlement Date, which shall be based upon documentation reasonably satisfactory to the Company demonstrating the difference (if greater than zero) between (A) the price per share paid by the Investor to purchase such number of shares of Common Stock necessary for the Investor to meet its share delivery obligations to such subsequent purchasers minus (B) the average Draw Down Discount Price during the applicable Draw Down Pricing Period in respect of such Settlement Date.

Without limiting the generality of the preceding sentence, the Company may, without the prior written consent of the Investor, (i) establish stock option, stock purchase, stock bonus or other equity incentive or award plans or agreements (for directors, employees, consultants and/or advisors), and issue securities thereunder, and amend such plans or agreements, including increasing the number of shares available thereunder, (ii) issue equity securities to finance, or otherwise in connection with, the acquisition, license or sale of one or more other companies, equipment, technologies or lines of business, (iii) issue shares of Common Stock and/or other securities in connection with the Company’s option, equity incentive or award plans, stock purchase plans, stock bonus programs, rights plans, warrants or options, (iv) issue shares of Common Stock and/or other securities in connection with the acquisition, license or sale of products, licenses, equipment or other assets and strategic collaborations, partnerships, joint ventures or similar transactions; (v) issue shares of Common and/or other securities to employees, consultants and/or advisors as consideration for services rendered or to be rendered, (vi) issue and sell equity or debt securities in a public offering, (vii) issue and sell any equity or debt securities in a private placement (other than in connection with any Prohibited Transaction), (viii) issue equity securities to equipment lessors, equipment vendors, banks or similar lending institutions in connection with leases or loans, or in connection with strategic, commercial or licensing transactions, including without limitation in connection with the Company’s current loan, or any future strategic, commercial or licensing transactions with, PharmaBio Development, Inc., (ix) issue securities in connection with any stock split, stock dividend, recapitalization, reclassification or similar event by the Company and (x) issue shares of Common Stock to the Investor under any other agreement entered into between the Investor and the Company.

Section 6.6 Prohibited Transactions. Except as set forth on Schedule 6.6 of the Disclosure Schedule and except as permitted by Section 6.5, 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 committed equity financing, including, without limitation, any financing that is substantially similar to the financing provided for under this Agreement, provided that any future issuance by the Company of (i) a convertible security (“Convertible Security”) that (A) contains provisions that adjust the conversion price of such Convertible Security in the event of stock splits, dividends, distributions, reclassifications or similar events or pursuant to anti-dilution provisions or (B) is issued in connection with the Company obtaining debt financing to support research and development activities where the issuance of Convertible Securities is conditioned upon or otherwise related to the Company meeting certain defined development milestones, (ii) securities in a registered direct public offering or an unregistered private placement where the price per share of such securities is fixed concurrently with the execution of definitive documentation relating to the offering or placement, as applicable and (iii) securities issued in connection with a secured debt financing, shall not be a Prohibited Transaction.

Section 6.7 Corporate Existence. The Company shall take all steps necessary to preserve and continue the corporate existence of the Company.

Section 6.8 Non-Disclosure of Non-Public Information. Subject to Section 6.9 below, except as otherwise expressly provided in this Agreement or the Warrant, none of the Company, its officers, directors, employees nor agents shall disclose material non-public information to the Investor, its advisors or representatives.

- 22 - -

Section 6.9 Notice of Certain Events Affecting Registration; Suspension of Right to Request a Draw Down. The Company shall promptly notify the Investor upon the occurrence of any of the following events in respect of the Registration Statement or the Prospectus related to the offer, issuance and sale of the Shares and the Warrant Shares hereunder: (i) receipt of any request for material additional information by the Commission or any other federal or state governmental authority or for amendments or supplements to the Registration Statement or the Prospectus during the period of effectiveness of the Registration Statement; (ii) the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; and (iii) receipt of any notification with respect to the suspension of the qualification or exemption from qualification of any of any capital securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, the Company shall use commercially reasonable efforts to obtain the withdrawal of such order at the earliest possible time. The Company shall not be required to disclose to the Investor the substance or specific reasons of any of the events set forth in clauses (i) through (iii) of the first sentence of this Section 6.9, only that the event has occurred. The Company shall not request a Draw Down during the continuation of any of the foregoing events.

Section 6.10 Amendments to the Registration Statement. The Company shall not file any amendment to the Registration Statement or make any amendment or supplement to the Prospectus (to the extent related to the sale of Shares hereunder) of which the Investor shall not have been previously or be simultaneously advised; provided, however, that the Company may, to the extent it deems advisable, and without the prior consent of or notice to the Investor, supplement the Prospectus within two (2) Trading Days following the Settlement Date for each Draw Down solely to reflect the issuance of Shares with respect to such Draw Down; and provided further that the Company need not advise the Investor regarding any supplement the purpose of which is to update the Registration Statement and the Prospectus to include information the Company has previously filed with the Commission pursuant to Section 13 or 15(d) of 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 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 IDEA filing system.

Section 6.11 Prospectus Delivery. From time to time for such period as in the reasonable opinion of counsel for the Investor a prospectus is required by the Securities Act to be delivered in connection with sales by the Investor, the Company will expeditiously deliver to the Investor, without charge, as many copies of the Prospectus (and of any amendment or supplement thereto related to sales by the Investor) as the Investor may reasonably request. The Company consents to the use of the Prospectus (and of any amendment or supplement thereto) in accordance with the provisions of the Securities Act and state securities laws in connection with the offering and sale of the Shares and the Warrant Shares and for such period of time thereafter as the Prospectus is required by the Securities Act to be delivered in connection with sales of the Shares and the Warrant Shares. Notwithstanding the foregoing, in no event shall the Company be under any obligation to the Investor 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 last Settlement Date with respect to such Draw Down.

Section 7.4 Effective Registration Statement. The Registration Statement shall have previously become effective and shall remain effective and (i) neither the Company nor the Investor shall have received notice that the Commission has issued or intends to issue a stop order with respect to the Registration Statement or that the Commission otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or intends or has threatened to do so (unless the Commission’s concerns have been addressed and the Investor is reasonably satisfied that the Commission no longer is considering or intends to take such action), and (ii) no other suspension of the use or withdrawal of the effectiveness of the Registration Statement or the Prospectus shall exist.

Section 7.5 No Knowledge. The Company shall have no Knowledge of any event that could reasonably be expected to have the effect of causing the Registration Statement with respect to the sale of the Shares to be suspended or otherwise ineffective (which event is reasonably likely to occur within eight Trading Days following the Trading Day on which a Draw Down Notice is delivered) as of the Settlement Date.

ARTICLE VIII

TERMINATION

Section 8.1 Term. Unless otherwise terminated in accordance with Section 8.2 below, this Agreement shall terminate upon the earlier to occur of (i) the expiration of the Commitment Period or (ii) the issuance of Shares pursuant to this Agreement in an amount equal to the Maximum Commitment Amount.

- 25 - -

Section 8.2 Other Termination; Blackout Periods.

(a) The Investor may terminate this Agreement upon (x) one (1) Trading Day’s notice if the Company enters into any Prohibited Transaction as set forth in Section 6.6 without the Investor’s prior written consent, or (y) one (1) Trading Day’s notice if the Investor provides written notice of a Material Adverse Effect to the Company, and such Material Adverse Effect continues for a period of ten (10) Trading Days after the receipt by the Company of such notice.

(b) The Company may terminate this Agreement upon one (1) Trading Day’s notice; provided, however, that the Company shall not terminate this Agreement pursuant to this Section 8.2(c) during any Draw Down Pricing Period; provided further, that, in the event of any termination of this Agreement by the Company pursuant to this Section 8.2(c), so long as the Investor owns Shares purchased hereunder, unless all of such shares of Common Stock may be sold by the Investor without registration and without any time, volume or manner limitations pursuant to Rule 144(b) (or any similar provision then in effect) under the Securities Act, the Company shall not suspend or withdraw the Registration Statement or otherwise cause the Registration Statement to become ineffective, or voluntarily delist the Common Stock from, the Principal Market without listing the Common Stock on another Principal Market.

(c) Each of the parties hereto may terminate this Agreement upon one (1) Trading Day’s notice if the other party has breached a material representation, warranty or covenant to this Agreement and such breach is not remedied within ten (10) Trading Days after notice of such breach is delivered to the breaching party.

(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 sales of securities of the Company 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 would adversely affect or require premature disclosure of such material development or potential material development (the Company’s notice thereof, a “Blackout Notice”), the Company shall have the right to 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 the Registration Statement to remain in effect during a Blackout Period and therefore essential to suspend the use thereof during such Blackout Period and agrees to cease any disposition of the Shares under the Registration Statement during such Blackout Period. The Company may not exercise any of its rights under this section to suspend the effectiveness of the Registration Statement more than six (6) times in any twelve (12) month period. In the event that, within five (5) Trading Days following any Settlement Date, 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 Shares 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 means the product of (i) the number of Shares purchased by the Investor pursuant to the most recent Draw Down and actually held by the Investor (and not otherwise sold, hypothecated or transferred) immediately prior to the Blackout Period and (ii) the result, if greater than zero, obtained by subtracting the New VWAP from the Old VWAP; provided, however, that no Blackout Amount shall be payable in respect of Shares (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 Shares 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 its 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”).

- 26 - -

Section 8.3 Effect of Termination. In the event of termination by the Company or the Investor, 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 8.1 or 8.2 herein, this Agreement shall become void and of no further force and effect, except as provided in Section 10.13. Nothing in this Section 8.3 shall be deemed to release the Company or the Investor from any liability for any breach under this Agreement occurring prior to such termination, or to impair the rights of the Company and the Investor to compel specific performance by the other party of its obligations under this Agreement arising prior to such termination.

ARTICLE IX

INDEMNIFICATION

Section 9.1 Indemnification.

(a) Except as otherwise provided in this Article IX, unless disputed as set forth in Section 9.2, the Company agrees to indemnify, defend and hold harmless the Investor and its affiliates and their respective officers, directors, agents, employees, subsidiaries, partners, members and controlling persons (each, an “Investor Indemnified Party”), to the fullest extent permitted by law from and against any and all Damages directly resulting from or directly arising out of any breach of any representation or warranty, covenant or agreement (except as otherwise specifically provided) by the Company in this Agreement; provided, however, that the Company shall not be liable under this Article IX to an Investor Indemnified Party to the extent that such Damages resulted or arose from the breach by an Investor Indemnified Party of any representation, warranty, covenant or agreement of an Investor Indemnified Party contained in this Agreement, or the negligence, recklessness, willful misconduct or bad faith of an Investor Indemnified Party. The parties intend that any Damages subject to indemnification pursuant to this Article IX will be net of insurance proceeds (which the Investor agrees to use commercially reasonable efforts to recover or to cause any Investor Indemnified Party to recover). Accordingly, the amount which the Company is required to pay to any Investor Indemnified Party hereunder (a “Company Indemnity Payment”) will be reduced by any insurance proceeds actually recovered by or on behalf of any Investor Indemnified Party in reduction of the related Damages. In addition, if an Investor Indemnified Party receives a Company Indemnity Payment required by this Article IX in respect of any Damages and subsequently receives any such insurance proceeds, then the Investor will pay, or will cause such other Investor Indemnified Party to pay, to the Company an amount equal to the Company Indemnity Payment received less the amount of the Company Indemnity Payment that would have been due if the insurance proceeds had been received, realized or recovered before the Company Indemnity Payment was made.

- 27 - -

(b) Except as otherwise provided in this Article IX, unless disputed as set forth in Section 9.2, the Investor agrees to indemnify, defend and hold harmless the Company and its affiliates and their respective officers, directors, agents, employees, subsidiaries, partners, members and controlling persons (each, a “Company Indemnified Party”), to the fullest extent permitted by law from and against any and all Damages directly resulting from or directly arising out of any breach of any representation or warranty, covenant or agreement by the Investor in this Agreement; provided, however, that the Investor shall not be liable under this Article IX to a Company Indemnified Party to the extent that such Damages resulted or arose from the breach by a Company Indemnified Party of any representation, warranty, covenant or agreement of a Company Indemnified Party contained in this Agreement or the negligence, recklessness, willful misconduct or bad faith of a Company Indemnified Party. The parties intend that any Damages subject to indemnification pursuant to this Article IX will be net of insurance proceeds (which the Company agrees to use commercially reasonable efforts to recover or to cause any Company Indemnified Party to recover). Accordingly, the amount which the Investor is required to pay to any Company Indemnified Party hereunder (an “Investor Indemnity Payment”) will be reduced by any insurance proceeds theretofore actually recovered by or on behalf of any Company Indemnified Party in reduction of the related Damages. In addition, if a Company Indemnified Party receives an Investor Indemnity Payment required by this Article IX in respect of any Damages and subsequently receives any such insurance proceeds, then the Company Indemnified Party will pay, or will cause such other Company Indemnified Party to pay, to the Investor an amount equal to the Investor Indemnity Payment received less the amount of the Investor Indemnity Payment that would have been due if the insurance proceeds had been received, realized or recovered before the Investor Indemnity Payment was made.

Section 9.2 Notification of Claims for Indemnification. Each party entitled to indemnification under this Article IX (an “Indemnified Party”) shall, promptly after the receipt of notice of the commencement of any claim against such Indemnified Party in respect of which indemnity may be sought from the party obligated to indemnify such Indemnified Party under this Article IX (the “Indemnifying Party”), notify the Indemnifying Party in writing of the commencement thereof. Any such notice shall describe the claim in reasonable detail. The failure of any Indemnified Party to so notify the Indemnifying Party of any such action shall not relieve the Indemnifying Party from any liability which it may have to such Indemnified Party (a) other than pursuant to this Article IX or (b) under this Article IX unless, and only to the extent that, such failure results in the Indemnifying Party’s forfeiture of substantive rights or defenses or the Indemnifying Party is prejudiced by such delay. The procedures listed below shall govern the procedures for the handling of indemnification claims.

- 28 - -

(a) Any claim for indemnification for Damages that do not result from a Third Party Claim as defined in the following paragraph, shall be asserted by written notice given by the Indemnified Party to the Indemnifying Party. Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such thirty (30) day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to make payment as set forth in Section 9.1. If such Indemnifying Party does not respond within such thirty (30) day period or rejects such claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as specified in this Agreement.

(b) If an Indemnified Party shall receive notice or otherwise learn of the assertion by a person or entity not a party to this Agreement of any threatened legal action or claim (collectively a “Third Party Claim”), with respect to which an Indemnifying Party may be obligated to provide indemnification, the Indemnified Party shall give such Indemnifying Party written notice thereof within twenty (20) days after becoming aware of such Third Party Claim.

(c) An Indemnifying Party may elect to defend (and, unless the Indemnifying Party has specified any reservations or exceptions, to seek to settle or compromise) at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel, any Third Party Claim. Within thirty (30) days after the receipt of notice from an Indemnified Party (or sooner if the nature of such Third Party Claim so requires), the Indemnifying Party shall notify the Indemnified Party whether the Indemnifying Party will assume responsibility for defending such Third Party Claim, which election shall specify any reservations or exceptions. If such Indemnifying Party does not respond within such thirty (30) day period or rejects such claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as specified in this Agreement. In case any such Third Party Claim shall be brought against any Indemnified Party, and it shall notify the Indemnifying Party of the commencement thereof, the Indemnifying Party shall be entitled to assume the defense thereof at its own expense, with counsel satisfactory to such Indemnified Party in its reasonable judgment; provided, however, that any Indemnified Party may, at its own expense, retain separate counsel to participate in such defense at its own expense. Notwithstanding the foregoing, in any Third Party Claim in which both the Indemnifying Party, on the one hand, and an Indemnified Party, on the other hand, are, or are reasonably likely to become, a party, such Indemnified Party shall have the right to employ separate counsel and to control its own defense of such claim if, in the reasonable opinion of counsel to such Indemnified Party, either (x) one or more significant defenses are available to the Indemnified Party that are not available to the Indemnifying Party or (y) a conflict or potential conflict exists between the Indemnifying Party, on the one hand, and such Indemnified Party, on the other hand, that would make such separate representation advisable; provided, however, that in such circumstances the Indemnifying Party (i) shall not be liable for the fees and expenses of more than one counsel to all Indemnified Parties and (ii) shall reimburse the Indemnified Parties for such reasonable fees and expenses of such counsel incurred in any such Third Party Claim, as such expenses are incurred, provided that the Indemnified Parties agree to repay such amounts if it is ultimately determined that the Indemnifying Party was not obligated to provide indemnification under this Article IX. The Indemnifying Party agrees that it will not, without the prior written consent of the Indemnified Party, settle, compromise or consent to the entry of any judgment in any pending or threatened claim 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 such Indemnified Party from all liability arising or that may arise out of such claim. The Indemnifying Party shall not be liable for any settlement of a claim effected against an Indemnified Party without the Indemnifying Party’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed. The rights accorded to an Indemnified Party hereunder shall be in addition to any rights that any Indemnified Party may have at common law, by separate agreement or otherwise; provided, however, that notwithstanding the foregoing or anything to the contrary contained in this Agreement, nothing in this Article IX shall restrict or limit any rights that any Indemnified Party may have to seek equitable relief.
