ARTICLE 1

PURCHASE, SALE AND TERMS OF NOTES

1.01 The Notes. The Company has authorized the issuance and sale to the Purchasers of the Company’s Subordinated Convertible Promissory Notes in the original aggregate principal amount of up to $10,000,000. The Subordinated Convertible Promissory Notes shall be substantially in the form set forth as Exhibit C hereto and are herein referred to individually as a “Note” and collectively as the “Notes,” which terms shall also include any notes delivered in exchange or replacement therefor.

1.02 Purchase and Sale of Notes.

(a) The Initial Closing. The Company agrees to issue and sell to the Initial Purchasers, and, subject to and in reliance upon the representations, warranties, covenants, terms and conditions of this Agreement, the Initial Purchasers agree to purchase the Notes in the principal amounts set forth opposite each Initial Purchaser’s name on Exhibit A hereto under the heading “Principal Amount of Notes To Be Purchased at the Initial Closing”. Such purchase and sale shall take place at a closing (the “Initial Closing”) to be held remotely via the exchange of documents on the date hereof at 12:00 p.m., Boston time, or at such other time or place as may be mutually agreed upon by the Company and the Initial Purchasers purchasing at least sixty-six and two-thirds percent (66 2/3%) of the principal amount of the Notes actually purchased at the Initial Closing.

(b) The Follow-On Closing. Following the Initial Closing, the Company will offer up to $1,419,000 total principal amount of Notes, on a pro rata basis (based on shares of the Company’s Common Stock, par value $0.001 per share (the “Common Stock”) issuable upon conversion of the Preferred Stock (as defined below) held by such holders), to the holders of the Company’s Preferred Stock who are not Initial Purchasers (the “Other Investors”). Any Other Investor who commits to purchase Notes shall execute an Additional Purchaser signature page to this Agreement, in substantially the form attached hereto as Schedule A, and shall thereafter be bound to this Agreement as an Additional Purchaser, and Exhibit B attached hereto shall be updated to include the principal amount of Notes that each Additional Purchaser has committed to purchasing. Forty percent (40%) of each Additional Purchaser’s commitment shall be funded at the Follow-On Closing (as defined below) and the remaining sixty percent (60%) shall be funded at the Second Closing (as defined below). The initial purchase and sale of the Notes to the Additional Purchasers shall take place at a closing (the “Follow-On Closing”) to be held no later than sixty (60) days after the Initial Closing. Any Notes offered to the Other Investors that are not purchased by the Other Investors may be purchased by the Initial Purchasers or the Additional Purchasers on a pro rata basis to the Notes purchased by such other Purchasers or on such other basis as may be agreed upon by the Company and the Purchasers holding at least 66 2/3% of the principal outstanding under the then outstanding Notes. For purposes of this Agreement, the additional Notes purchased in the Follow-On Closing by Initial Purchasers or the participating Additional Purchasers are the “Additional Follow-On Notes”.

(c) The Second Closing. After the Initial Closing and the Follow-On Closing, the Company shall sell, and the Purchasers shall purchase, Notes in the principal amounts set forth opposite each Purchaser’s name on Exhibit A (for Initial Purchasers) or Exhibit B (for Additional Purchasers) under the heading “Principal Amount of Notes to Be Purchased at the Second Closing.” Such purchase and sale shall take place at a closing (the “Second Closing” and together with the Initial Closing, the Follow-On Closing and the Final Closing (as defined below), the “Closings” and each individually a “Closing”) to be held no sooner than five (5) days and no later than ten (10) days following the approval by (A) the Board of Directors of the Company and (B) the Purchasers holding at least sixty-six and two-thirds percent (66 2/3%) of the principal amount of the outstanding Notes then held by all Purchasers of (i) a business plan and strategy for monetization of the Company’s corn CBP business and (ii) a plan for near- term acquisition opportunities for the Company (the “Second Closing Approval”); provided that if the Second Closing Approval does not occur on or before June 15, 2010, the Purchasers shall be relieved of their obligation to purchase any additional Notes hereunder. Notwithstanding the foregoing, if a Purchaser (an “Opting Out Purchaser”) obligated to purchase a Note at the Second Closing chooses not to purchase such Note at the Second Closing, such Opting Out Purchaser shall be relieved of its obligation to purchase such Note, but such Opting Out Purchaser shall be subject to the Mandatory Conversion described in Section 1.02(e). Each Purchaser shall give the Company notice, at least two (2) days prior to the Second Closing, if such Purchaser shall be an Opting Out Purchaser. Any Notes not purchased at the Second Closing by Opting Out Purchasers may be purchased at a final closing to be held within ten (10) days following the Second Closing (the “Final Closing”) by the other Purchasers on a pro rata basis to the Notes

purchased by such other Purchasers or on such other basis as may be agreed upon by the Company and the Purchasers holding at least 66 2/3% of the principal outstanding under the then outstanding Notes. For purposes of this Agreement, the additional Notes purchased in the Final Closing by Purchasers are the “Additional Opt Out Notes,” and together with the Additional Follow-On Notes, the “Additional Notes”.

(d) The Closings. At each Closing, each Purchaser participating in such Closing will deliver to the Company as payment in full for the Note to be purchased by such Purchaser at such Closing, by (i) a check payable to the Company’s order, (ii) wire transfer of funds to the Company, or (iii) any combination of the foregoing. At each Closing, the Company will issue and deliver to each Purchaser participating in such Closing a duly executed Note in the principal amount funded by such Purchaser at such Closing. The Company shall send the Notes to the Purchasers at the addresses furnished to the Company for that purpose.

(e) Mandatory Conversion. On the later to occur of (x) the date that is ten (10) days after the Second Closing or (y) the Special Mandatory Conversion Date (as such term is defined in the Restated Charter (as defined below)) each Opting Out Purchaser shall convert the portion of such Opting Out Purchaser’s shares of the Company’s Series A Preferred Stock, par value $0.001 per share (“Series A Preferred Stock”), Series A1 Preferred Stock, par value $0.001 per share (“Series A1 Preferred Stock”), Series B Preferred Stock, par value $0.001 per share (“Series B Preferred Stock”), and Series C Preferred Stock, par value $0.001 per share (“Series C Preferred Stock” and together with the Series A Preferred Stock, Series A1 Preferred Stock, Series B Preferred Stock, the “Preferred Stock”) that would have automatically been converted into shares of Common Stock as a result of the Special Mandatory Conversion set forth in the Restated Charter had the Opting Out Purchaser not initially agreed to purchase the Notes that were to have been sold to such Purchaser at the Second Closing had such Purchaser not chosen to become an Opting Out Purchaser (such conversion, a “Mandatory Conversion”), and shall surrender all of such Opting Out Purchaser’s stock certificates representing shares of Preferred Stock (or, if such Opting Out Purchaser alleges that such certificates have been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate) to the Company, and shall thereafter receive from the Company certificates for the number of shares of Common Stock to which such Opting Out Purchaser is entitled pursuant this Section 1.02(e), in addition to new certificates for the shares of Preferred Stock that remain following such conversion, if any, together with cash in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion. Upon the failure by an Opting Out Purchaser to request a conversion within the time period as set forth in this Section 1.02(e), such Opting Out Purchaser hereby grants the President and Treasurer of the Company (the “Proxies” and each a “Proxy”) a proxy coupled with an interest in all shares of Preferred Stock owned by such Opting Out Purchaser with the power to act alone and with full power of substitution, which proxy shall be irrevocable until this Agreement terminates pursuant to its terms, to request conversion of such Opting Out Purchaser’s shares of Preferred Stock into shares of Common Stock as specified in this Section 1.02(e). Upon the request of a Proxy of an

Opting Out Purchaser, the Company shall effect the Mandatory Conversion called for above on its books and records and shall issue the stock certificates for the number of shares of Common Stock to which such Opting Out Purchaser is entitled pursuant this Section 1.02(e), in addition to new certificates for the shares of Preferred Stock that remain following such conversion, if any, together with cash in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion upon receipt from the Opting Out Purchaser of its old Preferred Stock certificates (or, if such Opting Out Purchaser alleges that such certificates have been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate). Each Purchaser hereto acknowledges and agrees that any breach of this Section 1.02(e) would result in substantial harm to the Company for which monetary damages alone could not adequately compensate. Therefore, the parties hereto unconditionally and irrevocably agree that the Company shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity for breaches of this Section 1.02(e) and in addition shall be entitled to recover the costs of enforcing the Mandatory Conversion against any Opting Out Purchaser who fails to effect a Mandatory Conversion.

1.03 Issuance of Warrants. If the Notes are converted into New Equity Securities (as defined below) upon the closing of a Qualified Financing (as defined below), in connection with such conversion, the Company shall issue to each Purchaser, a warrant in substantially the form attached hereto as Exhibit E (each, a “Warrant” and collectively the “Warrants”), for that number of shares of New Equity Securities as is equal to fifty percent (50%) of the New Securities acquired by such Purchaser upon conversion of such Purchaser’s Notes; provided that if such Purchaser has purchased greater than such Purchaser’s Pro Rata Portion of Notes (as defined below), such Purchaser shall be entitled to receive that number of shares of New Equity Securities as is equal to one hundred percent (100%) of the New Securities acquired by such Purchaser upon conversion of that portion of the Notes that such Purchaser purchased in excess of such Purchaser’s Pro Rata Portion of Notes. For purposes of this Agreement, “Pro Rata Portion of Notes” means the aggregate principal amount of Notes for such Purchaser set forth opposite such Purchaser’s name on Schedule 1.03 attached hereto, which shall be updated in connection with the Follow-On Closing to add in the Additional Purchasers. For purposes of this Agreement, the term “Qualified Financing” shall mean the Company’s sale of its equity securities (the “New Equity Securities”) in a single transaction or in a series of related transactions in each case occurring after the date hereof and approved by the Company’s Board of Directors and the applicable stockholders of the Company, in which the Company receives aggregate gross proceeds of at least $5,000,000 (excluding all amounts payable under the Notes).

1.04 No Usury. This Agreement and each Note issued pursuant to the terms of this Agreement are hereby expressly limited so that in no event whatsoever, whether by reason of deferment or advancement of loan proceeds, acceleration of maturity of the loan evidenced hereby, or otherwise, shall the amount paid or agreed to be paid to the Purchasers hereunder for the loan, use, forbearance or detention of money exceed the maximum interest rate permitted by the laws of the Commonwealth of Massachusetts and

the State of New Hampshire. If at any time the performance of any provision hereof or any Note involves a payment exceeding the limit of the price that may be validly charged for the loan, use, forbearance or detention of money under applicable law, then automatically and retroactively, ipso facto, the agreed upon interest rate as set forth in the Notes shall be reduced to such limit, it being the specific intent of the Company and the Purchasers hereof that all payments under this Agreement or any Note are to be credited first to interest as permitted by law, but not in excess of (i) the agreed rate of interest set forth in the Note, or (ii) that permitted by law, whichever is the lesser, and the balance toward the reduction of principal. The provisions of this paragraph shall never be superseded or waived and shall control every other provision of this Agreement and any Note.

Form of Subordinated Convertible Promissory Note

THIS PROMISSORY NOTE AND THE SECURITIES ISSUABLE UPON CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF APPLICABLE STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION UNDER SUCH LAWS OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENT. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ALL APPLICABLE STATE SECURITIES LAWS.

THIS PROMISSORY NOTE IS SUBJECT TO THAT CERTAIN SUBORDINATION AGREEMENT AMONG THE LENDER (AS DEFINED BELOW) AND PINNACLE VENTURES L.L.C.

SUBORDINATED CONVERTIBLE PROMISSORY NOTE


$ [ ]		April , 2010

Subject to the terms and conditions of this Note, for value received, Mascoma Corporation, a Delaware corporation (the “Borrower”), hereby promises to pay to [ ] (the “Lender”), the principal sum of [ ] ($[ ]) (the “Principal Amount”), together with interest thereon accruing on and from the date hereof until the entire Balance is paid (or converted, as provided in Section 6 hereof), at an annual rate equal to five percent (5%). Interest shall be calculated based on a 365-day year, compounded annually, but in no event shall the rate of interest exceed the maximum rate, if any, allowable under applicable law. “Balance” means, at the applicable time, the sum of all then outstanding principal of this Note, all then accrued but unpaid interest and all other amounts then accrued but unpaid under this Note.

This subordinated convertible promissory note (the “Note”) is issued by the Borrower pursuant to that certain Subordinated Convertible Note Purchase Agreement dated as of the date hereof (the “Purchase Agreement”), entered into among the Borrower and the other parties thereto (the “Purchasers”), and is subject to, and Borrower and Lender shall be bound by, all the terms, conditions and provisions of the Purchase Agreement. This Note, and the other notes issued pursuant to the Purchase Agreement, are sometimes hereinafter referred to as the “Notes”. This Note is subordinated to indebtedness of the Borrower owed to Pinnacle Ventures L.L.C. (“Pinnacle”) pursuant to that certain Loan and Security Agreement, dated as of February 5, 2008, as amended to date (the “Pinnacle Agreement”), and any subsequent debt that the Borrower obtains from Pinnacle, or another senior lender in lieu of Pinnacle, whether through an amendment to the Pinnacle Agreement or entry into a new agreement, in addition to any amounts

owed by Borrower to Citibank under that standby letter of credit (the “Senior Debt”). Capitalized terms used herein but not defined herein shall have the meanings ascribed to them in the Purchase Agreement.

The following is a statement of the rights of Lender and the terms and conditions to which this Note is subject and to which the Lender, by acceptance of this Note, agrees:

1. Payment. If this Note has not been previously converted (as provided in Section 6 hereof), then at any time on or after September 30, 2010, provided that all Senior Debt has been repaid as of such date, the Requisite Purchasers shall have the right to require the Borrower to repay the Balance of all of the Notes then outstanding. The date on which the Balance of all of the Notes is repaid is referred to herein as the “Repayment Date.” Unless the indebtedness outstanding under this Note is converted in accordance with Section 6 hereof, all payments on account of principal and interest shall be made in lawful money of the United States of America at the principal office of the Lender, or such other place as the holder hereof may from time to time designate in writing to the Borrower.

2. No Prepayment. Except with regard to conversion of this Note under Section 6, Borrower may not prepay this Note without the written consent of the Requisite Purchasers.

3. Notes Pari Passu; Application of Payments. Each of the Notes shall rank equally without preference or priority of any kind over one another, and all payments and recoveries payable on account of principal and interest on the Notes shall be paid and applied ratably and proportionately on the Balances of all outstanding Notes on the basis of their original principal amount. Subject to the foregoing provisions, all payments will be applied first to the repayment of accrued fees and expenses under this Note, then to accrued interest until all then outstanding accrued interest has been paid in full, and then to the repayment of principal until all principal has been paid in full. If after all applications of such payments have been made as provided in this paragraph, then the remaining amount of such payments that are in either case in excess of the aggregate Balance of all outstanding Notes shall be returned to Borrower.

4. Transfer and Exchange. The holder of this Note may, prior to the Repayment Date or the conversion in full of such Note in accordance with Section 6, surrender such Note at the principal office of the Borrower for transfer or exchange. Within a reasonable time after notice to the Borrower from such holder of its intention to make such exchange and without expense to such holder, except for any transfer or similar tax which may be imposed on the transfer or exchange, the Borrower shall issue in exchange therefor another note or notes for the same aggregate principal amount as the unpaid principal amount of the Note so surrendered, having the same maturity and rate of interest, containing the same provisions and subject to the same terms and conditions as the Note so surrendered. Each new Note shall be made payable to such person or persons, or transferees, as the holder of such surrendered Note may designate, and such transfer or exchange shall be made in such a manner that no gain or loss of principal or interest shall result therefrom. The Borrower may elect not to permit a transfer of the Note if it has not obtained satisfactory assurance that such transfer: (a) is exempt from the registration requirements of, or covered by an effective registration statement under, the Securities Act of 1933, as amended, and the rules and regulations thereunder and (b) is in compliance with all

applicable state securities laws, including without limitation receipt of an opinion of counsel, which opinion shall be satisfactory to the Borrower.

5. New Note. Upon receipt of evidence reasonably satisfactory to the Borrower of the loss, theft, destruction or mutilation of the Note, the Borrower will issue a new Note, of like tenor and amount and dated the date to which interest has been paid, in lieu of such lost, stolen, destroyed or mutilated Note, and in such event the Lender agrees to indemnify and hold harmless the Borrower in respect of any such lost, stolen, destroyed or mutilated Note.

6. Conversion of Note. If the Borrower has not paid the entire Balance prior to the occurrence of such event, then the Balance then outstanding under this Note shall be automatically converted into equity securities of the Company upon the first to occur of (i) a Qualified Financing Closing (as defined below) and (ii) a Merger or Asset Transfer (as such terms are defined in the Company’s Restated Certificate, as may be amended from time to time (a Merger or Asset Transfer, collectively an “Acquisition”), as more fully described below.

(a) Conversion of Note upon a Qualified Financing. If a Qualified Financing Closing occurs prior to an Acquisition and the Borrower has not paid the entire Balance at the time of the Qualified Financing Closing, then at the Qualified Financing Closing, the entire Balance then outstanding under this Note shall be automatically converted into that number of shares of the security sold by the Borrower in the Qualified Financing (as defined below) as is equal to the Conversion Amount (as defined below) divided by the Qualified Financing Purchase Price (as defined below). Borrower shall deliver to Lender notice of the Qualified Financing as soon as practicable, but in any event no fewer than five (5) days prior to the scheduled closing date of the Qualified Financing, notifying the Lender of the conversion to be effected, including specifying (i) the Conversion Amount (calculated as of the Conversion Date), (ii) the Qualified Financing Purchase Price and (iii) the Conversion Date (as defined below).

(i) Qualified Financing Defined. For purposes of this Note, the term Qualified Financing shall mean the Borrower’s sale of its equity securities (the “New Equity Securities”) in a single transaction or in a series of related transactions in each case occurring after the date hereof and approved by the Borrower’s Board of Directors and the applicable stockholders of the Borrower, in which Borrower receives aggregate gross proceeds of at least $5,000,000 (excluding all amounts payable under the Notes). For purposes of this Note, “Qualified Financing Closing” means the closing of the Qualified Financing.

(ii) Qualified Financing Purchase Price Defined. For purposes of this Note, the term Qualified Financing Purchase Price shall mean an amount equal to the lowest per share purchase price at which shares of the New Equity Securities are or have been sold in the Qualified Financing as of the date of the conversion of this Note into such New Equity Securities.

(iii) Conversion Amount Defined. For purposes of this Note, the term Conversion Amount shall mean the sum of all unpaid principal and accrued

interest outstanding under this Note as of the Qualified Financing Closing or consummation of an Acquisition, as applicable.

(iv) Conversion Date Defined. For purposes of this Note, the term Conversion Date shall mean the Qualified Financing Closing or the date of the consummation of an Acquisition, as applicable.

(b) Conversion of Note upon an Acquisition. If an Acquisition occurs before a Qualified Financing Closing, and the Borrower has not paid the entire Balance at the time of the consummation of the Acquisition, then immediately prior to the Acquisition, the entire Balance then outstanding under this Note shall be automatically converted into that number of shares of the Company’s Series D Preferred Stock (the “Series D Preferred Stock,” and together with the New Equity Securities, the “Equity Securities”), as is equal to the Conversion Amount (as defined below) divided by $1.00 per share. Borrower shall deliver to Lender notice of the Acquisition as soon as practicable, but in any event no fewer than five (5) days prior to the Conversion Date, notifying the Lender of the conversion to be effected, including specifying (i) the Conversion Amount (calculated as of the Conversion Date), and (ii) the Conversion Date.

(c) Termination of Rights. Except for the rights to obtain certificates representing Equity Securities set forth in Section 6(d) below, all rights with respect to this Note shall terminate upon the effective conversion or repayment of the entire Balance of the Note, whether or not this Note has been surrendered to Borrower for cancellation.

(d) Delivery of Stock Certificates; No Fractional Shares. Subject to Section 6(c) above, as promptly as practicable after any conversion of this Note, Borrower at its expense will issue and deliver to Lender a certificate or certificates evidencing the number of full Equity Securities as are issuable to Lender in connection with a conversion under this Section 6. No fractional shares of any Equity Securities will be issued in connection with any conversion hereunder. In lieu of fractional shares which would otherwise be issuable, Borrower shall pay cash equal to the product of such fraction multiplied the price per share of the Equity Securities issuable to Lender upon such conversion.

7. Covenants. For so long as the Borrower shall have any amounts outstanding under any of the Notes, unless otherwise consented to in advance by the Requisite Purchasers:

(a) Limitations on Certain Indebtedness. While any amounts owned under this Note are outstanding, the Borrower will not itself, and will not permit any subsidiary to, create, assume, incur or in any manner become liable in respect of any Indebtedness (as defined below) other than Senior Debt. For purposes of this Agreement, Indebtedness shall mean and include the aggregate amount of, without duplication (i) all obligations for borrowed money, (ii) all obligations evidenced by bonds, debentures, notes or other similar instruments, (iii) all obligations to pay the deferred purchase price of property or services (other than accounts payable incurred in the ordinary course of business determined in accordance with generally accepted accounting principles), (iv) all obligations under capital leases, (v) all obligations or

liabilities of others secured by a lien on any assets, whether or not such obligation or liability is assumed, (vi) all guaranties of the obligations of another individual or entity, (vii) all obligations created or arising under any conditional sale or other title retention agreement with respect to property acquired (even if the rights and remedies of the seller or lender under such agreement upon an event of default are limited to repossession or sale of such property), (viii) net exposure under any interest rate swap, currency swap, forward, cap, floor or other similar contract that is not entered to in connection with a bona fide hedging operation that provides offsetting benefits, which agreements shall be marked to market on a current basis, and (ix) all reimbursement and other payment obligations, contingent or otherwise, in respect of letters of credit.

(b) Limitations on Liens. The Borrower will not itself, and will not permit any subsidiary to, create, assume or suffer to exist any Lien (as defined below) upon all or any part of its property of any character, whether owned at the date hereof or thereafter acquired, except for any Liens created with respect to the Senior Debt. For purposes of this Agreement, Lien shall mean with respect to any property, any security interest, mortgage, pledge, lien, claim, charge or other encumbrance in, of, or on such property or the income therefrom, including, without limitation, the interest of a vendor or lessor under a conditional sale agreement, capital lease or other title retention agreement, or any agreement to provide any of the foregoing, and the filing of any financing statement or similar instrument.

8. Events of Default. Each of the following shall constitute an “Event of Default” hereunder:

(a) The Borrower shall fail to pay any principal, interest or other amount payable hereunder on the applicable due date and such failure continues for five (5) days;

(b) The Borrower shall (1) voluntarily terminate operations or apply for or consent to the appointment of, or the taking of possession by, a receiver, custodian, trustee or liquidator of the Borrower or of all or a substantial part of the assets of the Borrower, (2) admit in writing its inability, to pay debts as the debts become due, (3) make a general assignment for the benefit of its creditors, (4) commence a voluntary case under the Federal Bankruptcy Code (as now or hereafter in effect), (5) file a petition seeking to take advantage of any other law relating to bankruptcy, insolvency, reorganization, winding-up, or composition or adjustment of debts, (6) fail to controvert in a timely and appropriate manner, or acquiesce in writing to, any petition filed against it in an involuntary case under the Federal Bankruptcy Code or applicable state bankruptcy laws or (7) take any corporate action for the purpose of effecting any of the foregoing;

(c) Without the Borrower’s application, approval or consent, a proceeding shall be commenced, in any court of competent jurisdiction, seeking in respect of the Borrower: the liquidation, reorganization, dissolution, winding-up, or composition or readjustment of debt, the appointment of a trustee, receiver, liquidator or the like relief in respect of the Borrower or all or any substantial part of the assets of the Borrower, or

other like relief in respect of the Borrower under any law relating to bankruptcy, insolvency, reorganization, winding-up, or composition or adjustment of debts; and, if the proceeding is being contested in good faith by the Borrower, the same shall continue undismissed, or unstayed and in effect for any period of 90 consecutive days, or an order for relief against the Borrower shall be entered in any case under the Federal Bankruptcy Code or applicable bankruptcy laws;

(d) The Borrower shall violate any of the covenants contained in Section 7 of this Note, or be in default under, any material agreement, instrument or other document relating to any indebtedness for money borrowed, including without limitation, any of the other Notes and such default persists beyond any applicable cure period; or

(e) The Borrower’s representations and warranties contained in the Purchase Agreement shall prove to have not been true in any material respect when made.

If an Event of Default shall occur pursuant to Sections 8(a), 8(d) and 8(e), then, at any time thereafter while such Event of Default is continuing, the Requisite Purchasers may by sending written notice to the Borrower (the “Default Notice”) declare the entire unpaid principal amount of this Note, together with all accrued and unpaid interest thereon, to be due and payable immediately. If an Event of Default shall occur pursuant to Sections 8(b) and 8(c), then the entire unpaid principal amount of this Note, together with all accrued and unpaid interest thereon shall be due and payable immediately.

2. Dividends. Subject to the rights and preferences of any Preferred Stock outstanding, dividends may be paid on the Common Stock out of funds legally available therefor as and when declared by the Board of Directors of the Corporation (the “Board of Directors”).

3. Liquidation Rights. Subject to the prior and superior right of any Preferred Stock outstanding, upon any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Corporation, the holders of Common Stock shall be entitled to receive distributions as provided in Article FOURTH, Part B below.

4. Relative Rights of Preferred Stock and Common Stock.

B.	PREFERRED STOCK

1. Dividends. The holders of shares of the Series A Preferred, the Series A1 Preferred, the Series B Preferred, the Series C Preferred and the Series D Preferred shall be

entitled to receive non-cumulative dividends in preference to holders of Common Stock, if and when declared by the Board of Directors from funds that are legally available therefore, on a pari passu basis in proportion to the preferential amount each such holder is entitled to receive, at the rate of $.064 per share per annum for the Series A Preferred, $.08 per share per annum for the Series A1 Preferred, $.2136 per share per annum for the Series B Preferred, $.512 per share per annum for the Series C Preferred, and $.08 per share per annum for the Series D Preferred (which amounts shall be subject to equitable adjustment whenever there shall occur a stock split, stock dividend, distribution, combination of shares, reclassification of shares, recapitalization or other similar event). The Corporation shall not declare, pay or set aside any dividends on any other shares of capital stock of the Corporation (other than dividends on shares of Common Stock payable in shares of Common Stock) unless the holders of the Series A Preferred, the Series A1 Preferred, the Series B Preferred, the Series C Preferred and the Series D Preferred then outstanding shall first receive a dividend on each outstanding share of the Series A Preferred, the Series A1 Preferred, the Series B Preferred, the Series C Preferred and the Series D Preferred in an amount at least equal to the amount described in the preceding sentence. The holders of Series A Preferred, Series A1 Preferred, Series B Preferred and Series C Preferred shall be entitled to participate pro rata on an as-converted-basis on any dividends paid to the holders of Common Stock.

2. Liquidation.

(a) Payments to Holders of Series D Preferred. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, the holders of shares of Series D Preferred then outstanding shall be entitled to be paid out of the assets of the Corporation available for distribution to its stockholders before any payment shall be made to the holders of Series A Preferred, Series A1 Preferred, Series B Preferred, Series C Preferred (collectively, the “Junior Preferred”) and Common Stock by reason of their ownership thereof, an amount per share equal to the sum of (A) five (5) times the Series D Original Issue Price (as defined below), plus (B) any dividends declared but unpaid thereon (the amount payable pursuant to this sentence is hereinafter referred to as the “Series D Liquidation Amount”). If upon any such liquidation, dissolution or winding up of the Corporation, the assets of the Corporation available for distribution to its stockholders shall be insufficient to pay the holders of shares of Series D Preferred the full amount to which they shall be entitled under this section, the holders of shares of Series D Preferred shall share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. “Series D Original Issue Price” means $1.00 per share (which amount shall be subject to equitable adjustment whenever there shall occur a stock split, stock dividend, distribution, combination of shares, reclassification of shares, recapitalization or other similar event).

(b) Payment to Junior Preferred Stock Upon Liquidation. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, after payment in full of the Series D Liquidation Amount to the holders of Series D Preferred, the holders of each share of Junior Preferred shall be entitled to receive an amount, such amount to be paid out of the remaining assets of the Corporation available for distribution, per share equal to the greater of (i) the Original Junior Preferred Issue Price (as defined below) plus all dividends

declared but unpaid thereon or (ii) if, immediately prior to such liquidation, dissolution or winding up, the holders of such shares would be entitled to convert such shares into shares of Common Stock pursuant to Section 3, the amount per share such holders would have received had such holders converted their shares of Junior Preferred into shares of Common Stock pursuant to Section 3 immediately prior to such liquidation, dissolution or winding up. The “Original Junior Preferred Issue Price” means the original purchase price per share for each share of Series A Preferred, Series A1 Preferred, Series B Preferred, and Series C Preferred as follows: $0.80 per share with respect to the Series A Preferred, $ 1.00 per share with respect to the Series A1 Preferred, $2.67 per share with respect to the Series B Preferred, and $6.40 per share with respect to the Series C Preferred (which amounts shall be subject to equitable adjustment whenever there shall occur a stock split, stock dividend, distribution, combination of shares, reclassification of shares, recapitalization or other similar event). “Original Issue Price” means the applicable Original Junior Preferred Issue Price or the Series D Original Issue Price, as applicable.

If the assets of the Corporation shall be insufficient to permit the payment in full to the holders of Junior Preferred all amounts distributable to them under this Section 2(b), then the remaining assets of the Corporation available for such distribution shall be distributed ratably among the holders of Junior Preferred on a pari passu basis in proportion to the full preferential amount each such holder is otherwise entitled to receive.

After such payments shall have been made in full to the holders of the Preferred Stock or funds necessary for such payments shall have been set aside by the Corporation in trust for the account of holders of Preferred Stock so as to be available for such payments, the remaining assets available for distribution shall be distributed among the holders of the Common Stock ratably in proportion to the number of shares of Common Stock held by them.

Upon conversion of shares of Junior Preferred into shares of Common Stock pursuant to Section 3, the holder of such Common Stock shall not be entitled to any preferential payment or distribution in case of any liquidation, dissolution or winding up of the Corporation, but shall share ratably in any distribution of the assets of the Corporation to all the holders of Common stock.

(c) Distributions Other than Cash. Whenever the distribution provided for in this Section 2 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property as determined in good faith by the Board of Directors.

(d) Merger as Liquidation etc. The (i) consolidation or merger of the Corporation with or into any other corporation or other entity or person, or any other corporate reorganization, other than any consolidation, merger or reorganization in which the stockholders of the Corporation immediately prior to such consolidation, merger or reorganization, continue to hold at least a majority of the voting power of the surviving entity in substantially the same proportions immediately after such consolidation, merger or reorganization (or, if the surviving entity is a wholly owned subsidiary, a consolidation or merger with its parent) or any transaction or series of related transactions to which the Corporation is a party in which in excess of fifty percent (50%) of the Corporation’s voting power is transferred (a “Merger” provided that a Merger shall not include any transaction or series of transactions principally for bona fide equity

financing purposes in which cash is received by the Corporation or any successor or indebtedness of the Corporation is cancelled or converted or a combination thereof); or (ii) sale, lease, exclusive license or other disposition of all or substantially all of the assets of the Corporation (unless such sale, lease, license or disposition is to a corporation or other entity the equity ownership of which reflects a change of fifty percent (50%) or less in voting power from the percentage voting power of the shareholders of the Corporation before such transaction) (an “Asset Transfer”), shall be a Deemed Liquidation Event, dissolution or winding up of the Corporation for purposes of this Section 2 unless (A) the holders of at least sixty-six and two- thirds percent (66 2/3%) of the then outstanding shares of Junior Preferred (voting as a single class on an as converted basis) and (B) the holders of at least sixty-six and two-thirds percent (66 2/3%) of the then outstanding shares of Series D Preferred (voting together as a separate class) elect to the contrary by giving written notice thereof to the Corporation at least three days before the effective date of such event. If such notice is given, the provisions of Section 3(h) shall apply. The amount deemed distributed to the holders of Preferred Stock upon any such merger or consolidation shall be the cash or the value of the property, rights or securities distributed to such holders by the acquiring person, firm or other entity. The value of such property, rights or other securities shall be determined in good faith by the Board of Directors.

(e) Notice and Opportunity to Exercise Conversion Rights. Notwithstanding anything to the contrary that may be inferred from the provisions of this Section 2, each holder of shares of Junior Preferred shall be entitled to receive notice from the Corporation pursuant to Section 6(b) hereof of any proposed liquidation, dissolution or winding up of the Corporation at least 20 days prior to date on which any such liquidation, dissolution or winding up of the Corporation is scheduled to occur and, at any time prior to any such liquidation, dissolution or winding up of the Corporation, to convert any or all of such holder’s shares of Junior Preferred into shares of Common Stock pursuant to Section 3 hereof.

3. Conversion. The holders of the Junior Preferred shall have conversion rights as follows (the “Conversion Rights”):

(a) Right to Convert; Conversion Prices. Each share of Junior Preferred shall be convertible, without the payment of any additional consideration by the holder thereof and at the option of the holder thereof, at any time after the date of issuance of such share, at the office of the Corporation or any transfer agent for such Junior Preferred, into such number of fully paid and nonassessable shares of Common Stock as is determined by dividing the Original Junior Preferred Issue Price of such share by the Conversion Price (as defined below) for such share, determined as hereinafter provided, in effect at the time of conversion. The “Conversion Price” shall mean, with respect to any share of Junior Preferred, the price at which shares of Common Stock shall be deliverable upon conversion without the payment of any additional consideration by the holder of such share. The Conversion Price of a share of Junior Preferred shall initially be the Original Junior Preferred Issue Price of such share. The initial Conversion Price shall be subject to adjustment, in order to adjust the number of shares of Common Stock into which the Junior Preferred is convertible, as hereinafter provided.

(b) Termination of Conversion Rights. In the event of a notice of redemption of any shares of Junior Preferred pursuant to Section 4, the Conversion Rights of such shares designated for redemption pursuant to Section 3(a) shall terminate at the close of business on the

last full day preceding the date fixed for redemption, unless the Redemption Price (as defined herein) is not fully paid on such Redemption Date (as defined herein), in which case the Conversion Rights for such shares shall continue until such price is paid in full. In the event of a liquidation, dissolution or winding up of the Corporation or a Deemed Liquidation Event, the Conversion Rights shall terminate at the close of business on the last full day preceding the date fixed for the payment of any such amounts distributable on such event to the holders of Junior Preferred, unless such payments are not fully paid on such day, in which case the Conversion Rights for such shares shall continue until such payment is paid in full.

(c) Automatic Conversion. Each share of Junior Preferred shall automatically be converted into shares of Common Stock at the then effective Conversion Price upon (i) the written election of holders of sixty-six and two-thirds percent (66 2/3%) of the Junior Preferred then outstanding, voting as a single class on an as converted basis (an “Automatic Conversion Election”) or (ii) the closing of a public offering, underwritten by an investment banking firm approved by the holders of sixty-six and two-thirds percent (66 2/3%) of the shares of Junior Preferred then outstanding, voting as a single class, pursuant to an effective registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock for the account of the Corporation to the public for a total offering of at least $20,000,000 (a “Qualifying Initial Public Offering”). In the event of a Qualifying Initial Public Offering, the person(s) entitled to receive the Common Stock issuable upon such conversion of the Junior Preferred shall not be deemed to have converted their Junior Preferred until the closing of the Qualifying Initial Public Offering.

Upon the effective date of an Automatic Conversion Election or the closing of the Qualifying Initial Public Offering, all shares of Junior Preferred shall be converted automatically without any further action by the holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent; provided, however, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion unless certificates evidencing such shares of Junior Preferred being converted are either delivered to the Corporation or its transfer agent, or the holder of such shares notifies the Corporation or any transfer agent that such certificates have been lost, stolen, or destroyed and executes an agreement reasonably satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection therewith. Upon the automatic conversion of the Junior Preferred, the holders of such Junior Preferred shall surrender the certificates representing such shares at the office of the Corporation or of its transfer agent. Thereupon, there shall be issued and delivered to such holder, promptly at such office and in his name as shown on such surrendered certificate or certificates, a certificate or certificates for the number of shares of Common Stock into which the shares of the Junior Preferred surrendered were convertible on the date on which such automatic conversion occurred. No fractional shares of Common Stock shall be issued upon conversion of the Junior Preferred. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then effective Conversion Price.

(d) Mechanics of Conversion. Before any holder of Junior Preferred shall be entitled to convert the same into full shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly endorsed for transfer or with duly executed stock transfer

powers sufficient to permit transfer attached, at the office of the Corporation or of any transfer agent for the Junior Preferred (or such holder shall notify the Corporation or any transfer agent that such certificates have been lost, stolen or destroyed and shall execute an agreement reasonably satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection therewith), and shall give written notice to the Corporation at such office that such holder elects to convert the same and shall state therein such holder’s name or the name or names of such holder’s nominees in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. No fractional shares of Common Stock shall be issued upon conversion of the Junior Preferred. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the then effective Conversion Price. The Corporation shall promptly pay in cash or, to the extent sufficient funds are not then legally available therefor, in Common Stock (at the Common Stock’s fair market value determined by the Board of Directors as of the date of such conversion), any declared and unpaid dividends on the shares of Junior Preferred being converted. The Corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Junior Preferred, or to such holder’s nominee or nominees, a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid, together with cash in lieu of any fraction of a share. Except as set forth in the second paragraph of Section 3(c), such conversion shall be deemed to have been made immediately prior to the close of business on the date of such surrender of the certificates for the shares of Junior Preferred to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date.

(e) Adjustments to Conversion Price for Diluting Issues.

(1) “Option” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Common Stock or Convertible Securities.

(ii) No Adjustment of Conversion Price. No adjustment in the number of shares of Common Stock into which Junior Preferred is convertible shall be made, by adjustment in the Conversion Price, in respect of the issuance of Additional Shares of Common Stock or otherwise, unless the consideration per share for an Additional Share of Common Stock issued or deemed to be issued by the Corporation is less than the relevant Conversion Price in effect on the date of, and immediately prior to, the issue of such Additional Share of Common Stock.

(iii) Issue or Sale of Securities Deemed Issue of Additional Shares of Common Stock.

(1) Options and Convertible Securities. In the event the Corporation at any time or from time to time after the Original Junior Preferred Issue Date shall issue or sell any Options or Convertible Securities (other than those excluded from the definition of Additional Shares of Common Stock in Section 3(e)(i)(4) pursuant to clauses (i)(4)(A), (i)(4)(B), (i)(4)(C), (i)(4)(D), (i)(4)(E) or (i)(4)(J) thereof) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number) of Common Stock issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or sale or, in case such a record date shall have been fixed, as of the close of business on such record date; provided, however, that Additional Shares of Common Stock shall not be deemed to have been issued unless the consideration

per share (determined pursuant to Section 3(e)(v)) received for such Additional Shares of Common Stock would be less than the Conversion Price in effect on the date of and immediately prior to such issue or sale or such record date, as the case may be; and provided further, that in any such case in which Additional Shares of Common Stock are deemed to be issued;

(A) no further adjustment in the Conversion Price shall be made upon the subsequent issue of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities;

(B) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any change in the consideration payable to the Corporation, or change in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Conversion Price computed upon the original issue hereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such change becoming effective, be recomputed to reflect such change insofar as it affects such Options or the rights of conversion or exchange under such Convertible Securities;

(C) upon the expiration of any such Options or any rights of conversion or exchange under such Convertible Securities that shall not have been exercised, the Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration, be recomputed as if:

(I) in the case of Convertible Securities or Options for Common Stock, the only Additional Shares of Common Stock issued were the shares of Common Stock, if any, actually issued upon the exercise of such Options or the conversion or exchange of such Convertible Securities, and the consideration received therefor was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration actually received by the Corporation upon such exercise, or for the issue of all such Convertible Securities that were actually converted or exchanged, plus the additional consideration, if any, actually received by the Corporation upon such conversion or exchange; and

(II) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued upon the exercise thereof were issued at the time of issue of such Options, and the consideration received by the Corporation for the Additional Shares of Common Stock deemed to have been then

issued was the consideration actually received by the Corporation for the issue of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Corporation (determined pursuant to Section 3(e)(v)) upon the issue of the Convertible Securities with respect to which such Options were actually exercised;

(D) in the case of any Options that expire by their terms not more than 30 days after the date of issue thereof, no adjustment of the applicable Conversion Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the same manner provided in clause (C) above; and

(E) if such record date shall have been fixed and such Options or Convertible Securities are not issued on the date fixed therefor, the adjustment previously made in the Conversion Price that became effective on such record date shall be cancelled as of the close of business on such record date, and thereafter the applicable Conversion Price shall be adjusted pursuant to this Section 3(e)(iii) as of the actual date of their issuance.

(2) Stock Dividends Stock Distributions and Subdivisions. In the event the Corporation at any time or from time to time after the Original Junior Preferred Issue Date shall declare or pay any dividend or make any other distribution on the Common Stock payable in Common Stock or effect a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise) then and in any such event, Additional Shares of Common Stock shall be deemed to have been issued:

(A) in the case of any such dividend or distribution, immediately after the close of business on the record date for the determination of holders of any class of securities entitled to receive such dividend or distribution; or

(B) at the time at which such corporate action becomes effective.

If such record date shall have been fixed and no part of such dividend shall have been paid on the date fixed therefor, the adjustment previously made in the Conversion Price that became effective on such record date shall be cancelled as of the close of business on such record date, and thereafter the Conversion Price shall be adjusted pursuant to this Section 3(e)(iii) as of the time of actual payment of such dividend.

(iv) Adjustment of Conversion Price Upon Issuance, Sale or Deemed Issuance of Additional Shares of Common Stock. In the event that at any time or from time to time after the Original Junior Preferred Issue Date, the Corporation shall issue or sell Additional Shares of Common Stock (including, without limitation, Additional

Shares of Common Stock deemed to be issued pursuant to Section 3(e)(iii)(l) but not including Additional Shares of Common Stock deemed to be issued pursuant to Section 3(e)(iii)(2) as a result of a dividend or other distribution on the Common Stock payable in Common Stock or a subdivision of outstanding shares of Common Stock), without consideration or for a consideration per share less than the Conversion Price of a particular series of Junior Preferred in effect on the date of and immediately prior to such issue or sale, then and in such event, the Conversion Price with respect to such Junior Preferred shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined in accordance with the following formula;


New Conversion Price =		P1 Q1 + P2 Q2
New Conversion Price =		Q1 + Q2


where:

	P1	=	Conversion Price of Junior Preferred in effect immediately prior to such new issue or sale.

	Q1	=	Number of shares of Common Stock deemed outstanding immediately prior to such new issue or sale.

	P2	=	Weighted average price per share of Common Stock received by the Corporation upon such new issue or sale.

	Q2	=	Number of shares of Common Stock issued or sold, or deemed to have been issued, in the subject transaction.

For the purpose of this Section 3(e)(iv), (i) the number of shares of Common Stock outstanding at any given time shall exclude shares in the treasury of the Corporation or shares of Common Stock held for the account of the Corporation or any of its subsidiaries; and (ii) all shares of Common Stock issuable upon conversion or exercise of shares of Junior Preferred, other Convertible Securities and options outstanding immediately prior to the issue or sale of Additional Shares of Common Stock triggering the adjustment provided for, by this Section 3(e)(iv) shall be deemed to be outstanding shares of Common Stock for purposes of calculating such adjustment. Anything contained in this Section 3(e)(iv) to the contrary notwithstanding, the applicable Conversion Price shall not be reduced at any time if the amount of such reduction would be an amount less than $.01, but any such amount shall be carried forward and reduction with respect thereto made at the time of and together with any subsequent reduction that, together with such amount and any other amount or amounts so carved forward, shall aggregate $.01 or more.

(v) Determination of Consideration. For purposes of this Section 3(e), the consideration received by the Corporation for the issue of any Additional Shares of Common Stock shall be computed as follows:

(1) Cash and Property: Such consideration shall:

(A) insofar as it consists of cash, be computed at the aggregate amounts of cash received by the Corporation excluding amounts paid or payable for accrued interest or accrued dividends;

(B) insofar as it consists of property other than cash, be computed at the fair value thereof at the time of such issue or sale, as determined in good faith by the Board of Directors; and

(C) in the event Additional Shares of Common Stock are issued together with other shares or securities or other assets of the Corporation for consideration that covers both, be the proportion of such consideration so received, computed as provided in clauses (A) and (B) above, as determined in good faith by the Board of Directors.

(2) Options and Convertible Securities. The consideration per share received by the Corporation for Additional Shares of Common Stock deemed to have been issued pursuant to Section 3(e)(iii)(l) relating to Options and Convertible Securities shall be determined by dividing (x) the total amount, if any, received or receivable as consideration for the issue of such Options or Convertible Securities plus the minimum aggregate amount, of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Corporation upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities by (y) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.

(vi) Adjustment for Dividends. Distributions, Subdivisions, Combinations or Consolidations of Common Stock.

(1) Stock Dividends Distributions or Subdivisions. In the event Additional Shares of Common Stock shall be deemed to have been issued in a dividend or other distribution on the Common Stock payable in Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise) described in Section 3(e)(iii)(2), the Conversion Price in effect immediately prior to the record date or effectiveness, as the case may be, of such

dividend, distribution or subdivision shall, concurrently with such record date or effectiveness, be proportionately decreased.

(2) Combinations or Consolidations. In the event the outstanding shares of Common Stock shall be combined or consolidated (by reclassification or otherwise) into a lesser number of shares of Common Stock, the Conversion Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased.

(f) Adjustments for Certain Dividends and Distributions. In the event that at any time or from time to time after the Original Junior Preferred Issue Date the Corporation shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event provision shall be made so that the holders of Junior Preferred shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the amount of securities of the Corporation that they would have received had their Junior Preferred been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by them as aforesaid during such period, giving application during such period to all adjustments called for herein.

(g) Adjustment for Reclassification, Exchange, or Substitution. In the event that at any time or from time to time after the Original Junior Preferred Issue Date, the Common Stock issuable upon the conversion of Junior Preferred shall be changed into the same or a different number of shares of any class or classes of stock, whether by capital reorganization, reclassification, or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a merger, consolidation or sale of assets provided for below), then and in each such event the holder of each such share of Junior Preferred shall have the right thereafter to convert such share, into the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification or other change, by a holder of the number of shares of Common Stock into which such share of Junior Preferred might have been converted immediately prior to such reorganization, reclassification or change, all subject to further adjustment as provided herein. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 3 with respect to the rights of the holders of Junior Preferred after the capital reorganization to the end that the provisions of this Section 3 (including adjustment of the Conversion Price for each series of Junior Preferred then in effect and the number of shares issuable upon conversion of each series of Junior Preferred) shall be applicable after that event and be as nearly equivalent as practicable.

(h) Adjustment for Merger or Asset Transfer. In the event that at any time or from time to time after the Original Junior Preferred Issue Date, the Corporation shall merge or consolidate with or into another entity or sell, lease, give an exclusive license to, or otherwise dispose of all or substantially all of its assets (other than a Merger or Asset Transfer that is treated as a liquidation pursuant to Section 2(c)), each share of Junior Preferred shall thereafter be convertible into the kind and amount of shares of stock or other securities or property to which a holder of the number of shares of Common Stock of the Corporation deliverable upon

conversion of such Junior Preferred would have been entitled upon such consolidation, merger or sale; and, in such case, appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions in this Section 3 set forth with respect to the rights and interest thereafter of the holders of Junior Preferred, to the end that the provisions set forth in this Section 3 (including provisions with respect to changes in and other adjustments of the Conversion Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the conversion of the Junior Preferred.

(i) Waiver of Anti-dilution Protection. To the extent that the provisions of Sections 3(e), 3(f). 3(g) and 3(h) apply, such provisions may be waived by the written consent of the holders of at least sixty-six and two-thirds percent (66 2/3%) in voting power of shares of Junior Preferred then outstanding. For the purposes of this Section 3(i), a waiver on one occasion shall not constitute a waiver on any further occasion.

(j) Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment of any Conversion Price pursuant to this Section 3, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each affected holder of Junior Preferred a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon the written request at any time of any affected holder of Junior Preferred, furnish or cause to be furnished to such holder a like certificate setting forth such adjustments and readjustments, summarizing the principal facts upon which such adjustment or readjustment is based, including a statement of (i) the consideration received or deemed to be received by the Corporation for any Additional Shares of Common Stock issued or sold or deemed to have been issued or sold, (ii) the Conversion Price at the time in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received upon the conversion of each share of Junior Preferred. Failure to request or provide such notice shall have no effect on any such adjustment.

(k) Notices of Record Date. Upon (i) any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or (ii) any Merger (as defined in Section 2(c)) or other capital reorganization of the Corporation, any reclassification or recapitalization of the capital stock of the Corporation, any Asset Transfer (as defined in Section 2(c)), or any voluntary or involuntary dissolution, liquidation or winding up of the Corporation, the Corporation shall mail to each holder of Junior Preferred at least 10 days prior to (x) the record date, if any, specified therein; or (y) if no record date is specified, the date upon which such action is to take effect (or, in either case, such shorter period approved by the holders of sixty-six and two-thirds percent (66 2/3%) of the outstanding Junior Preferred, voting as a single class on an as converted basis) a notice specifying (A) the date on which any such record is to be taken for the purpose of such dividend or distribution and a description of such dividend or distribution, (B) the date on which any such Merger, reorganization, reclassification, transfer, Asset Transfer, dissolution, liquidation or winding up is expected to become effective and the date before which the holders of at least sixty-six and two-thirds percent (66 2/3%) of the then outstanding shares of Junior Preferred, voting as a single class on an as converted basis, must elect for Section 3(h) to apply, and (C) the date, if any, that is to be fixed as to when the holders

of record of Common Stock (or other securities) shall be entitled to exchange their shares of Common Stock (or other securities) for securities or other property deliverable upon such Merger, reorganization, reclassification, transfer, Asset Transfer, dissolution, liquidation or winding up.

(1) Common Stock Reserved. The Corporation shall reserve and keep available out of its authorized but unissued Common Stock such number of shares of Common Stock as shall from time to time be sufficient to effect conversion of Junior Preferred. If at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of Junior Preferred, the Corporation will take such corporate action as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose.

(m) Certain Taxes. The Corporation shall pay any issue or transfer taxes payable in connection with the conversion of Junior Preferred; provided, however, that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer to a name other than that of the holder of Junior Preferred.

(n) Closing of Books. The Corporation shall at no time close its transfer books against the transfer of any Junior Preferred or of any shares of Common Stock issued or issuable upon the conversion of any shares of Junior Preferred in any manner that interferes with the timely conversion or transfer of such Junior Preferred or Common Stock, except as may otherwise be required by applicable law.

3A. Special Mandatory Conversion.

3.A.1 Trigger Event. In the event that any holder of shares of Junior Preferred does not participate in a Designated Financing (as defined below) by purchasing in the aggregate, in such Designated Financing and within the time period specified by the Corporation, such holder’s Pro Rata Amount (as defined below), then the Applicable Portion (as defined below) of the shares of Junior Preferred held by such holder shall automatically, and without any further action on the part of such holder, be converted into shares of Common Stock at the Conversion Price in effect immediately prior to the consummation of such Designated Financing, effective upon, subject to, and within 60 days of the consummation of the initial closing of the Designated Financing. For purposes of determining the number of shares of Junior Preferred owned by a holder, and for determining the number of Offered Securities (as defined below) a holder of Junior Preferred has purchased in a Designated Financing, all shares of Junior Preferred held by Affiliates (as defined below) of such holder shall be aggregated with such holder’s shares and all Offered Securities purchased by Affiliates of such holder shall be aggregated with the Offered Securities purchased by such holder (provided that no shares or securities shall be attributed to more than one entity or person within any such group of affiliated entities or persons). Such conversion is referred to as a “Special Mandatory Conversion.”

3A.2 Procedural Requirements. Upon a Special Mandatory Conversion, each holder of shares of Junior Preferred converted pursuant to Subsection 3A.1 shall

be sent written notice of such Special Mandatory Conversion and the place designated for mandatory conversion of all such shares of Junior Preferred pursuant to this Section 3A. Upon receipt of such notice, each holder of such shares of Junior Preferred shall surrender his, her or its certificate or certificates for all such shares (or, if such holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation at the place designated in such notice. If so required by the Corporation, certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. All rights with respect to the Junior Preferred converted pursuant to Subsection 3A.1, including the rights, if any, to receive notices and vote (other than as a holder of Common Stock), will terminate at the time of the Special Mandatory Conversion (notwithstanding the failure of the holder or holders thereof to surrender the certificates for such shares at or prior to such time), except only the rights of the holders thereof, upon surrender of their certificate or certificates therefor (or lost certificate affidavit and agreement), to receive the items provided for in the next sentence of this Subsection 3A.2. As soon as practicable after the Special Mandatory Conversion and the surrender of the certificate or certificates (or lost certificate affidavit and agreement) for Junior Preferred so converted, the Corporation shall issue and deliver to such holder, or to his, her or its nominees, a certificate or certificates for the number of full shares of Common Stock issuable on such conversion in accordance with the provisions hereof, together with cash as provided in Subsection 3(d) in lieu of any fraction of a share of Common Stock otherwise issuable upon such conversion and the payment of any declared but unpaid dividends on the shares of Junior Preferred converted and a new certificate for the number of shares, if any, of Junior Preferred represented by such surrendered certificate and not converted pursuant to Subsection 3A.1. Such converted Junior Preferred shall be retired and cancelled and may not be reissued as shares of such series, and the Corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to reduce the authorized number of shares of Junior Preferred accordingly.

3A.3 Definitions. For purposes of this Section 3A, the following definitions shall apply:

3A.3.1 “Affiliate” shall mean, with respect to any holder of shares of Junior Preferred, any person, entity or firm which, directly or indirectly, controls, is controlled by or is under common control with such holder, including, without limitation, any entity of which the holder is a partner or member, any partner, officer, director, member or employee of such holder and any venture capital fund now or hereafter existing of which the holder is a partner or member which is controlled by or under common control with one or more general partners of such holder or shares the same management company with such holder.

3A.3.2 “Applicable Portion” shall mean, with respect to any holder of shares of Junior Preferred, a number of shares of Junior Preferred calculated by multiplying the aggregate number of shares of Junior Preferred held by such holder immediately prior to a Designated Financing by a fraction, the numerator of which is equal to the amount, if positive, by which such holder’s Pro Rata Amount exceeds the number of Offered Securities actually purchased by such holder in such Designated Financing, and the denominator of which is equal to such holder’s Pro Rata Amount. If a holder of Junior Preferred holds more than one series of Junior Preferred then the Applicable Portion shall consist equally of each series (for example, if a holder of Junior Preferred holds both Series B Preferred and Series C Preferred and only purchases 50% of his, her or its Pro Rata Amount then 50% of the Series B Preferred and 50% of the Series C Preferred held by such holder of Junior Preferred will be converted in the Special Mandatory Conversion).

3A.3.3 “Designated Financing” shall mean any transaction involving the issuance or sale of Notes pursuant to the Note Purchase Agreement after the Original Junior Preferred Issue Date.

3A.3.4 “Offered Securities” shall mean the debt securities of the Corporation set aside by the Board of Directors for purchase by holders of outstanding shares of Junior Preferred in connection with a Designated Financing, and offered to such holders, provided that Offered Securities shall not include any Additional Notes (as defined in the Note Purchase Agreement) offered to such holders.

3A.3.5 “Pro Rata Amount” shall mean, with respect to any holder of Junior Preferred, the lesser of (a) a number of Offered Securities calculated by multiplying the aggregate number of Offered Securities by a fraction, the numerator of which is equal to the number of shares of Junior Preferred (on as converted to Common Stock basis) owned by such holder, and the denominator of which is equal to the aggregate number of outstanding shares of Junior Preferred (on as converted to Common Stock basis) or (b) the maximum number of Offered Securities that such holder is permitted by the Corporation to purchase in such Designated Financing, after giving effect to any cutbacks or limitations established by the Board of Directors and applied on a pro rata basis to all holders of Junior Preferred.

4. Redemption.

(a) Redemption. Shares of Series A Preferred, Series A1 Preferred, Series B Preferred, the Series C Preferred and Series D Preferred (collectively, the “Redemption Stock”) shall be redeemed by the Corporation out of funds lawfully available therefore (i) with respect to the Series D Preferred at a price per share equal to the sum of (A) five (5) times the Series D Original Issue Price plus (B) any declared but unpaid dividends thereon (the “Series D Redemption Price”) and (ii) with respect to the Junior Preferred at a price per share equal to the Original Junior Preferred Issue Price with respect to such shares, plus any declared but unpaid dividends thereon (the “Junior Preferred Redemption Price,” and together with the Series D

Redemption Price, the “Redemption Price” ), in three annual installments commencing 60 days after receipt by the Corporation at any time on or after the seven year anniversary of the first issuance of any shares of Series D Preferred from the holders of at least sixty-six and two-thirds percent (66 2/3%) of the then outstanding shares of Series D Preferred, of written notice requesting redemption of all shares of Redemption Stock (the date of each such installment being referred to as a “Redemption Date”). On each Redemption Date, the Corporation shall redeem, on a pro rata basis in accordance with the number of shares of Redemption Stock owned by each holder, that number of outstanding shares of Redemption Stock determined by dividing (A) the total number of shares of Redemption Stock outstanding immediately prior to such Redemption Date by (B) the number of remaining Redemption Dates (including the Redemption Date to which such calculation applies). If the Corporation does not have sufficient funds legally available to redeem on any Redemption Date all shares of Redemption Stock, the Corporation shall first redeem a pro rata portion of each holder’s Series D Preferred and may then redeem a pro rata portion of each holder’s Junior Preferred out of funds legally available therefor, based on the respective amounts which would otherwise be payable in respect of the shares to be redeemed if the legally available funds were sufficient to redeem all such shares, and shall redeem the remaining shares to have been redeemed as soon as practicable after the Corporation has funds legally available therefore, provided that at all times, shares of Series D Preferred shall be redeemed prior to any shares of Junior Preferred.

(b) Redemption Notice. Written notice of the mandatory redemption (the “Redemption Notice”) shall be sent to each holder of record of Redemption Stock not less than 20 days prior to each Redemption Date. Each Redemption Notice shall state:

(i) the number of shares of Redemption Stock held of record by the holder that the Corporation shall redeem on the Redemption Date specified in the Redemption Notice;

(ii) the Redemption Date and the Redemption Price;

(iii) the date upon which the holder’s right to convert such shares terminates (as determined in accordance with Section 3(b)); and

(iv) that the holder is to surrender to the Corporation, in the manner and at the place designated, his, her or its certificate or certificates representing the shares of Redemption Stock to be redeemed.

(c) Surrender of Certificates; Payment. On or before the applicable Redemption Date, each holder of shares of Redemption Stock to be redeemed on such Redemption Date, unless such holder has exercised his, her or its right to convert shares of Junior Preferred as provided in Section 3(a), shall surrender the certificate or certificates representing such shares (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and agreement reasonably acceptable to the Corporation to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of such certificate) to the Corporation, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price for such shares shall be payable to the order of the person whose name appears on such

certificate or certificates as the owner thereof. In the event less than all of the shares of Preferred Stock represented by a certificate are redeemed, a new certificate representing the unredeemed shares of Redemption Stock shall promptly be issued to such holder.

(d) Rights Subsequent to Redemption Date. If the Redemption Notice shall have been duly given, and if on the applicable Redemption Date the Redemption Price payable upon redemption of the shares of Redemption Stock to be redeemed on such Redemption Date is paid or tendered for payment or deposited with an independent payment agent so as to be available therefor, then notwithstanding that the certificates evidencing any of the shares of Redemption Stock so called for redemption shall not have been surrendered, dividends with respect to such shares of Redemption Stock shall cease to accrue after such Redemption Date and all rights with respect to such shares shall forthwith after the Redemption Date terminate, except only the right of the holders to receive the Redemption Price without interest upon surrender of their certificate or certificates therefor.

5. Voting Rights. Except as otherwise required by law or hereinafter set forth, the holders of Junior Preferred and the holders of Common Stock shall be entitled to notice of any meeting of stockholders and to vote as one class upon any matter submitted to the stockholders for a vote, on the following basis:

(a) Holders of Common Stock shall have one vote per share; and

(b) Holders of Junior Preferred shall have that number of votes per share as is equal to the number of shares of Common Stock into which each such share of Junior Preferred held by such holder could be converted on the date for determination of stockholders entitled to vote at the meeting or on the date of any written consent.

Without limiting the generality of the foregoing, and notwithstanding the provisions of Section 242(b)(2) of the General Corporation Law, the number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of Junior Preferred and Common Stock, voting as one class in accordance with the provisions of this Section 5. Except as otherwise hereinafter set forth, with respect to all questions as to which, under law, stockholders are entitled to vote by classes, the Junior Preferred shall vote together as a single class separately from the Common Stock.

6. Covenants.

(a) As long as at least 20% of the originally issued Junior Preferred remain outstanding, the Corporation shall not, either directly or indirectly by amendment of this Certificate of Incorporation, merger, consolidation, operation of law or otherwise, without first having provided the written notice of such proposed action to each holder of outstanding shares of Junior Preferred required by Section 6(b) and having obtained the affirmative vote or written consent of the holders of not less than sixty-six and two-thirds percent (66 2/3%) of the voting power of the then outstanding shares of Junior Preferred, voting together as a single class, with each share of Junior Preferred entitling the holder thereof to that number of votes per share as is

equal to the number of shares of Common stock into which each such share of Junior Preferred held by such holder could then be converted:

(i) alter or change the rights, preferences, or privileges of the Preferred Stock;

(ii) increase or decrease the authorized number of shares of Common Stock or Preferred Stock;

(iii) create (by reclassification or otherwise), authorize or issue any other class or classes of stock or series of Common Stock or Preferred Stock or any security convertible into or evidencing the right to purchase shares of any class or series of Common Stock or Preferred Stock or any capital stock of the Corporation having rights, preferences or privileges senior to or in parity with the Preferred Stock in any respect;

(iv) redeem, purchase, retire or otherwise acquire for value (or pay into or set aside for a sinking fund, or apply any of its assets, for such purpose), or declare and pay or set aside funds for the, payment of any dividend with respect to, any share or shares of capital stock, directly or indirectly, through subsidiaries or otherwise, except for: (A) the repurchase of unvested shares from officers, employees, directors or consultants of the Corporation at cost, pursuant to the terms of agreements that were entered into in connection with the original issuance of such capital stock (or options to purchase such capital stock), (B) a redemption approved by a Majority of the Directors or (C) the repurchase of shares pursuant to an agreement or arrangement previously approved by holders of Preferred Stock;

(v) pay or declare any dividend or distribution on any shares of Common Stock or Preferred Stock;

(vi) increase or decrease the authorized number of directors of the Corporation;

(vii) effect any Asset Transfer (other than the grant of a mortgage or security interest in connection with indebtedness for borrowed money), any liquidation, dissolution or winding up of the Corporation, or any Merger;

(viii) amend the terms of Common Stock, including increasing or decreasing the authorized number of shares of Common Stock;

(ix) authorize any transaction with senior management of the Corporation, except for arms length employment agreements approved by the Board of Directors; or

(x) otherwise amend the Corporation’s Certificate of Incorporation or by-laws.

(b) Any other provision of the Corporation’s Certificate of Incorporation or by-laws to the contrary notwithstanding, notice of any action specified in Section 6(a) shall be given by the Corporation to each holder of outstanding shares of Junior Preferred by overnight delivery or first class mail, postage prepaid, addressed to such holder at the last address of such holder as shown by the records of the Corporation, at least 20 days before the date on which the books of the Corporation shall close or a record shall be taken with respect to such proposed action, or, if there shall be no such date, at least 20 days before the date when such proposed action is scheduled to occur. The holders of at least sixty-six and two-thirds percent (66 2/3%) of the outstanding shares of Junior Preferred may waive any notice required by Section 2(d) and this Section 6(b) by a written document indicating such waiver.

7. Election of Board of Directors.

(a) The holders of Junior Preferred, voting as a single class, shall be entitled to elect three (3) members of the Board at each meeting or pursuant to each consent of the Corporation’s stockholders for the election of directors, and to remove from office such directors and to fill any vacancy caused by the resignation, death or removal of such directors.

(b) The holders of Common Stock, voting as a separate class, shall be entitled to elect two (2) members of the Board of Directors at each meeting or pursuant to each consent of the Corporation’s stockholders for the election of directors, and to remove from office such directors and to fill any vacancy caused by the resignation, death or removal of such directors.

(c) The holders of at least sixty-six and two-thirds percent (66 2/3%) of the Common Stock and Junior Preferred, voting together as a single class on an as-if-converted basis, shall be entitled to elect all remaining members of the Board of Directors at each meeting or pursuant to each consent of the Corporation’s stockholders for the election of directors, and to remove from office such directors and to fill any vacancy caused by the resignation, death or removal of such directors.

8. No Reissuance of Preferred Stock. No share or shares of Preferred Stock acquired by the Corporation by reason of redemption, purchase, conversion or otherwise shall be reissued, and all such shares shall be cancelled, retired and eliminated from the shares that the Corporation shall be authorized to issue.

FIFTH: In furtherance of and not in limitation of powers conferred by statute, it is further provided that:

(a) Subject to the limitations and exceptions, if any, contained in the by-laws of the Corporation and this Certificate of Incorporation, such by-laws may be adopted, amended or repealed by the Board of Directors; and

(b) Elections of directors need not be by written ballot unless, and only to the extent, otherwise provided in the by-laws of the Corporation; and

(c) Subject to any applicable requirements of law, the books of the Corporation may be kept outside the State of Delaware at such location or locations as may be designated by the Board of Directors or in the by-laws of the Corporation; and

(d) Except as provided to the contrary in the provisions establishing a class of stock, the number of authorized shares of such class may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the stock of the Corporation entitled to vote, voting as a single class.

SIXTH: The Corporation shall indemnify each person who at anytime is, or shall have been, a director or officer of the Corporation and was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement incurred in connection with any such action, suit or proceeding, to the maximum extent permitted by the General Corporation Law, as the same exists or may hereafter be amended. The foregoing right of indemnification shall in no way be exclusive of any other rights of indemnification to which any such director or officer may be entitled, under any by-law, agreement, vote of directors or stockholders or otherwise. No amendment to or repeal of the provisions of this Article SIXTH shall deprive a director or officer of the benefit hereof with respect to any act or failure to act occurring prior to such amendment or repeal. In furtherance of and not in limitation of the foregoing, the Corporation shall advance expenses, including attorneys’ fees, incurred by a director or officer of the Corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such advances if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation. Notwithstanding the foregoing, the Corporation shall not be required to indemnify or advance expenses to any person in connection with any action, suit, proceeding, claim or counterclaim initiated by or on behalf of such person.

SEVENTH: Whenever a compromise or arrangement is proposed between this Corporation and its creditors or any class of them or between this Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of this Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for this Corporation under Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for this Corporation under Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this Corporation, as the case may be, to be summoned in such manner as said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this Corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of this Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made; be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of this Corporation, as the case may be, and also on this Corporation.

EIGHTH: No director of the Corporation shall be personally liable to the Corporation or to any of its stockholders for monetary damages arising out of such director’s breach of fiduciary duty as a director of the Corporation, except to the extent that the elimination or limitation of such liability is not permitted by the General Corporation Law, as the same exists or may hereafter be amended. No amendment to or repeal of the provisions of this Article EIGHTH shall deprive any director of the Corporation of the benefit hereof with respect to any act or failure to act of such director occurring prior to such amendment or repeal.

NINTH: The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation in the manner now or hereafter prescribed by the General Corporation Law and this Certificate of Incorporation, and all rights conferred upon stockholders herein are granted subject to this reservation.

TENTH: The Corporation renounces any interest or expectancy of the Corporation in, or in being offered an opportunity to participate in, any Excluded Opportunity. An “Excluded Opportunity” is any matter, transaction or interest that is presented to, or acquired, created or developed by, or which otherwise comes into the possession of, (i) any director of the Corporation who is not an employee of the Corporation or any of its subsidiaries, or (ii) any holder of Preferred Stock or any partner, member, director, stockholder, employee or agent of any such holder, other than someone who is an employee of the Corporation or any of its subsidiaries (collectively, “Covered Persons”), unless such matter, transaction or interest is presented to, or acquired, created or developed by, or otherwise comes into the possession of, a Covered Person expressly and solely in such Covered Person’s capacity as a director of the Corporation.

WARRANT TO PURCHASE STOCK


No. W-

THIS CERTIFIES THAT, for value received, , with its principal office at , or its assigns (the “Holder”), is entitled to subscribe for and purchase from MASCOMA CORPORATION, a Delaware corporation (the “Company”), with its principal office at 00 Xxxx Xxxx, Xxxxx 000, Xxxxxxx, XX 00000, [ ] shares of the Company’s [ ] [INSERT NUMBER (AS CALCULATED BELOW) AND TYPE OF SHARES] at the Exercise Price (each as defined below).

This Warrant is being issued as one of a series of warrants pursuant to the terms of the Subordinated Convertible Note Purchase Agreement, dated April , 2010, by and among the Company and the purchasers therein (the “Purchase Agreement”). Capitalized terms not otherwise defined herein shall have the meaning given to such terms in the Purchase Agreement. Unless indicated otherwise, the Holder may purchase up to [ ] shares of the Company’s [ ] (the “Shares”) upon exercise of this Warrant.

[INSERT NUMBER AND TYPE OF SHARES IN THE BLANKS ABOVE, WITH THE NUMBER OF SHARES BASED ON THE BELOW FORMULA:

In connection with the Company’s sale of its equity securities in a single transaction or in a series of related transactions, approved by the Company’s Board of Directors and the applicable stockholders of the Company, in which the Company receives aggregate gross proceeds of at least $5,000,000 (excluding amounts payable under the Notes) (a “Qualified Financing”), where the Notes convert into the equity securities of the Company sold in such Qualified Financing, that number of shares equal to fifty percent (50%) of the equity securities acquired by the Holder upon conversion of such Holder’s Notes, provided that with respect to a Holder that

purchases greater than such Holder’s pro rata portion of Notes, such Holder shall receive, for that portion of the Notes that such Holder purchased above such Holder’s pro rata portion, that number of shares equal to one hundred percent (100%) of the equity securities acquired by the Holder upon conversion of such portion in excess of such Holders’ pro rata portion ]

1. DEFINITIONS. As used herein, the following terms shall have the following respective meanings:

(a) “Exercise Period” shall mean the period commencing on the date hereof and ending five (5) years thereafter.

(b) “Exercise Price” shall mean [ ] [INSERT PRICE PER SHARE], which shall equal the price at which the securities are sold in the Qualified Financing], subject to adjustment pursuant to Section 5 below.

2. EXERCISE OF WARRANT. The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth above (or at such other address as it may designate by notice in writing to the Holder):

(a) An executed Notice of Exercise in the form attached hereto;

(b) Payment of the Exercise Price either (i) in cash or by check, or (ii) by cancellation of indebtedness; and

(c) This Warrant.

Upon the exercise of the rights represented by this Warrant, a certificate or certificates for the Shares so purchased, registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable time after the rights represented by this Warrant shall have been so exercised.

The person in whose name any certificate or certificates for Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was surrendered and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

2.1 Net Exercise. Notwithstanding any provisions herein to the contrary, immediately following the closing of the Company’s first sale of its Common Stock to the public in an offering underwritten by an investment banking firm, pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Act”) (the “Initial Public Offering”), if the fair market value of one share of the Company’s Common Stock issuable hereunder is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant by payment of cash, the Holder may elect to receive shares equal to

the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Notice of Exercise in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula:


X =		Y (A-B)
		A



Where	X =	the number of Shares to be issued to the Holder

	Y =	the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being canceled (at the date of such calculation)

	A =	the fair market value of one share of the Company’s Common Stock purchasable under the Warrant (at the date of such calculation)

	B =	Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the fair market value per share of Common Stock shall be the average of the closing prices of the Common Stock, on the securities exchange on which such Common Stock is traded following the Initial Public Offering, for five trading days immediately prior to the exercise date. If the Common Stock is traded on other than a securities exchange, then the fair market value per share of Common Stock shall be determined in good faith by the Company’s Board of Directors.

3. COVENANTS OF THE COMPANY.

3.1 Covenants as to Shares. The Company covenants and agrees that all Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from preemptive rights, a sufficient number of shares of its shares of [ ] [NTD: INSERT TYPE OF STOCK] to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of [ ] [NTD: INSERT TYPE OF STOCK] shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of [ ] [NTD: INSERT TYPE OF STOCK] to such number of shares as shall be sufficient for such purposes.

3.2 No Impairment. Except and to the extent as waived or consented to by the Holder, the Company will not, by amendment of its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all

such action as may be necessary or appropriate in order to protect the exercise rights of the Holder against impairment.

3.3 Notices of Record Date. In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend which is the same as cash dividends paid in previous quarters) or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the date specified herein, a notice specifying the date on which any such record is to be taken for the purpose of such dividend or distribution.

4. REPRESENTATIONS OF HOLDER.

4.1 Acquisition of Warrant for Personal Account. The Holder represents and warrants that it is acquiring the Warrant and the Shares solely for its account for investment and not with a view to or for sale or distribution of said Warrant or Shares or any part thereof. The Holder also represents that the entire legal and beneficial interests of the Warrant and Shares the Holder is acquiring is being acquired for, and will be held for, its account only.

4.2 Securities Are Not Registered.

(a) The Holder understands that the Warrant and the Shares have not been registered under the Act on the basis that no distribution or public offering of the stock of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention.

(b) The Holder recognizes that the Warrant and the Shares must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available. The Holder recognizes that the Company has no obligation to register the Warrant or the Shares of the Company, or to comply with any exemption from such registration.

(c) The Holder is aware that neither the Warrant nor the Shares may be sold pursuant to Rule 144 adopted under the Act unless certain conditions are met, including, among other things, the existence of a public market for the shares, the availability of certain current public information about the Company, the resale following the required holding period under Rule 144 and the number of shares being sold during any three month period not exceeding specified limitations. Holder is aware that the conditions for resale set forth in Rule 144 have not been satisfied and that the Company presently has no plans to satisfy these conditions in the foreseeable future.

4.3 Disposition of Warrant and Shares.

(a) The Holder further agrees not to make any disposition of all or any part of the Warrant Shares in any event unless and until:

(i) The Company shall have received a letter secured by the Holder from the Securities and Exchange Commission stating that no action will be recommended to the Commission with respect to the proposed disposition;

(ii) There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with said registration statement; or

(iii) The Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, for the Holder to the effect that such disposition will not require registration of such Warrant or Shares under the Act or any applicable state securities laws.

(iv) Notwithstanding the provisions of paragraphs (i), (ii) and (iii) above, no such registration statement or opinion of counsel shall be necessary for a transfer by a Holder that is (A) a partnership transferring to its partners or former partners in accordance with partnership interests or to an affiliate of such partnership, (B) a corporation transferring to a wholly-owned subsidiary or a parent corporation that owns all of the capital stock of the Holder, (C) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company or to an affiliate of such limited liability company, or (D) an individual transferring to the Holder’s family member or trust for the benefit of an individual Holder; provided that in each case the transferee will be subject to the terms of this Warrant to the same extent as if it were an original Holder hereunder.

(b) The Holder understands and agrees that all certificates evidencing the shares to be issued to the Holder may bear the following legend:

“THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF APPLICABLE STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION UNDER SUCH LAWS OR AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENT. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ALL APPLICABLE STATE SECURITIES LAWS.”

5. Adjustments. Subject to the expiration of this Warrant pursuant to Section 1, the number and kind of shares purchasable hereunder and the Exercise Price therefor are subject to adjustment from time to time, as follows:

(a) Merger or Reorganization. If at any time there shall be any reorganization, recapitalization, merger or consolidation (other than a merger solely to effect a reincorporation of the Company into another state) (a “Reorganization”) involving the Company (other than as otherwise provided for herein or as would cause the expiration of this Warrant under Section 1) in which shares of the Company’s stock are converted into or exchanged for securities, cash or other property, then, as a part of such Reorganization, lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant, the kind and amount of securities, cash or other property of the successor corporation resulting from such Reorganization, equivalent in value to that which a holder of the Shares deliverable upon exercise of this Warrant would have been entitled in such Reorganization if the right to purchase the Shares hereunder had been exercised immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the board of directors of the successor corporation) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near as reasonably may be, in relation to any shares or other securities deliverable after that event upon the exercise of this Warrant.

(b) Reclassification of Shares. If the securities issuable upon exercise of this Warrant are changed into the same or a different number of securities of any other class or classes by reclassification, capital reorganization, conversion of all outstanding shares of the relevant class or series (other than as would cause the expiration of this Warrant pursuant to Section 1) or otherwise (other than as otherwise provided for herein) (a “Reclassification”), then, in any such event, in lieu of the number of Shares which the Holder would otherwise have been entitled to receive, the Holder shall have the right thereafter to exercise this Warrant for a number of shares of such other class or classes of stock that a holder of the number of securities deliverable upon exercise of this Warrant immediately before that change would have been entitled to receive in such Reclassification, all subject to further adjustment as provided herein with respect to such other shares.

(c) Subdivisions and Combinations. In the event that the outstanding shares of preferred stock are subdivided (by stock split, by payment of a stock dividend or otherwise) into a greater number of shares of such securities, the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately increased, and the Exercise Price shall be proportionately decreased, and in the event that the outstanding shares of preferred stock are combined (by reclassification or otherwise) into a lesser number of shares of such securities, the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such combination shall, concurrently with the effectiveness of such combination, be proportionately decreased, and the Exercise Price shall be proportionately increased.

(d) Redemption. In the event that all of the outstanding shares of the securities issuable upon exercise of this Warrant are redeemed in accordance with the Company’s certificate of incorporation, this Warrant shall thereafter be exercisable for a number of shares of the Company’s Common Stock equal to the number of shares of common stock that would have been received if this Warrant had been exercised in full immediately prior to such redemption and the preferred stock received thereupon had been simultaneously converted into common stock.

(e) Notice of Adjustments. Upon any adjustment in accordance with this Section 5, the Company shall give notice thereof to the Holder, which notice shall state the event giving rise to the adjustment, the Exercise Price as adjusted and the number of securities or other property purchasable upon the exercise of the rights under this Warrant, setting forth in reasonable detail the method of calculation of each. The Company shall, upon the written request of any Holder, furnish or cause to be furnished to such Holder a certificate setting forth (i) such adjustments, (ii) the Exercise Price at the time in effect and (iii) the number of securities and the amount, if any, of other property that at the time would be received upon exercise of this Warrant.

6. FRACTIONAL SHARES. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current fair market value of a Share by such fraction.

7. AUTOMATIC EXERCISE. If the Holder of this Warrant has not elected to exercise this Warrant prior to expiration of this Warrant pursuant to Section 1(a) then this Warrant shall automatically (without any act on the part of the Holder) be exercised pursuant to Section 2.1 effective immediately prior to the expiration of the Warrant to the extent such net issue exercise would result in the issuance of Shares. If this Warrant is automatically exercised, the Company shall notify the Holder of the automatic exercise as soon as reasonably practicable, and the Holder shall surrender the Warrant to the Company in accordance with the terms hereof.

8. NO STOCKHOLDER RIGHTS. This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.

9. TRANSFER OF WARRANT. Subject to applicable laws and the restriction on transfer set forth on the first page of this Warrant, this Warrant and all rights hereunder are transferable, by the Holder in person or by duly authorized attorney, upon delivery of this Warrant and the form of assignment attached hereto to any transferee designated by Holder. The transferee shall sign an investment letter in form and substance satisfactory to the Company.

10. LOST, STOLEN, MUTILATED OR DESTROYED WARRANT. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender

thereof), issue a new Warrant of like denomination and tenor as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

11. NOTICES, ETC. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex, facsimile or electronic mail if sent during normal business hours of the recipient, if not, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at the address listed on the signature page and to Holder at its address listed on the first page of this Warrant or at such other address as the Company or Holder may designate by ten (10) days advance written notice to the other parties hereto.

12. ACCEPTANCE. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

13. AMENDMENT AND WAIVER. Any term of this Warrant may be amended or waived with the written consent of the Company and the Requisite Purchasers as provided in Section 5.02 of the Purchase Agreement; provided, however, that any amendment or waivers must apply to all Holders in the same manner. Holder acknowledges that because this Warrant may be amended with the consent of the Requisite Purchasers, Holder’s rights hereunder may be amended or waived without Holder’s consent. Upon the effectuation of such waiver or amendment in conformance with this Section 13, the Company shall promptly give written notice thereof to the record Holders of the Warrants who have not previously consented thereto in writing.

14. GOVERNING LAW. This Warrant and all rights, obligations and liabilities hereunder shall be governed by, and construed and enforced in accordance with, the substantive laws of the State of Delaware without regard to its principles of conflicts of laws.

IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by its duly authorized officer as of , .
