**1.01 Entry into a Material Definitive Agreement.**

*Subscription Agreement and Issuance of Preferred Units*

On March 6, 2026, OPAL Fuels LLC ("<u>OPAL Fuels LLC</u>"), a Delaware limited liability company and subsidiary of OPAL Fuels Inc. (the "<u>Company</u>"), entered into a Subscription Agreement (the "<u>Subscription Agreement</u>") and related documentation with Preferred Fuels LLC (the "<u>Investor</u>"), an affiliate of Fortistar LLC.

Pursuant to the Subscription Agreement, the Investor committed to purchase from OPAL Fuels LLC up to 1,800,000 Series A Preferred Units ("<u>Units</u>") at a price of $100 per Unit, for an aggregate purchase price of up to $180,000,000 (the "<u>Offering</u>") in multiple closings. Upon the first closing under the Subscription Agreement on March 6, 2026 (the "<u>Initial Closing</u>"), the Investor purchased 1,200,000 Units for an aggregate purchase price of $120,000,000 (the "<u>Initial Investment</u>"), and OPAL Fuels LLC may, in its sole discretion, require the Investor to fund up to an additional $60,000,000 of unfunded committed investments (the "<u>Additional Investments</u>") within one year of the Initial Closing subject to certain terms and conditions set forth in the Subscription Agreement.

Pursuant to the Subscription Agreement, the Investor also has a right of first offer to purchase up to an additional 700,000 Units for an aggregate purchase price of up to $70,000,000 in the Offering in the event that OPAL Fuels LLC intends to sell any additional Units prior to the two (2) year anniversary of the Initial Closing.

The proceeds from the Initial Investment were used to redeem all of the outstanding Series A preferred units issued by OPAL Fuels LLC held by Mendocino Capital, LLC, a wholly owned subsidiary of NextEra Energy, Inc. Funds remaining available after such redemption may be used by OPAL Fuels LLC for general corporate purposes, including working capital, capital expenditures of OPAL Fuels LLC and its affiliates, as well as any project-level financing in respect of the projects identified in the Subscription Agreement.

The Units will be entitled to preferred quarterly distributions equal to 12% per annum, compounding quarterly (the "<u>Preferred Coupon</u>"). OPAL Fuels LLC at its sole discretion may choose to pay one-sixth of the Preferred Coupon in kind with respect to such quarterly period. The Units shall rank senior to all other classes of equity interests of OPAL Fuels LLC except the existing Series A-1 Preferred Units owned by Hillman RNG Investments LLC to which the Units are pari-passu, except with regard to certain protective provisions such as the right of the holder of the Units to appoint a director as described in Item 3.02 of this Current Report on Form 8-K, which right is not applicable to the Series A-1 Preferred Units.

The foregoing descriptions of the Subscription Agreement (including the transactions contemplated therein) and the Units do not purport to be complete and are subject in their entirety to the full text of the Subscription Agreement (including the description of the transactions included therein) filed hereto as Exhibit 10.1, the Amended and Restated Certificate of Designations for the Series A Preferred Units filed hereto as Exhibit 3.1, and the Second Amended and Restated Limited Liability Company Agreement of OPAL Fuels LLC.

*Investor Warrant*

In connection with the Initial Closing of the Offering, the Company issued to the Investor a warrant (the "<u>Warrant</u>") to purchase up to 3,000,000 shares of Class A Common Stock (the "<u>Warrant Shares</u>") of the Company, in substantially the form filed hereto as Exhibit 4.1. The Warrant Shares are issuable in multiple tranches as follows: (i) at the Initial Closing, 2,160,000 Warrant Shares were issued to the Investor; of which up to 720,000 Warrant Shares (the "<u>Additional Warrant Shares</u>") are subject to forfeiture if the Additional Investments are requested by OPAL Fuels LLC pursuant to the terms of the Subscription Agreement within one year of the Initial Closing (the "<u>Availability Period</u>"), and are not funded by the Investor within the time period set forth in the Subscription Agreement, which number of forfeited Additional Warrant Shares shall be equal to the product of 720,000 multiplied by a fraction, the numerator of which is the amount of unfunded Additional Investments and the denominator of which is $60,000,000; and (ii) within two (2) years of the Initial Closing, up to an additional 840,000 Warrant Shares (the "<u>Subsequent Warrant Shares</u>") shall be issuable on a pro rata basis in connection with each purchase by the Investor of up to an additional 700,000 Units for an aggregate purchase price of up to $70,000,000, with the number of Subsequent Warrant Shares issuable in connection with each such purchase equal to the product of 840,000 multiplied by a fraction, the numerator of which is the amount purchased and the denominator of which is $70,000,000. The exercise price per Warrant Share is equal to the sum of (x) the volume-weighted average price per share of Class A common stock on the Nasdaq Capital Market for the twenty (20) consecutive trading days ending on (and including) the trading day immediately preceding the issuance date of the Warrant, plus (y) $0.50, or as subsequently adjusted as provided in the Warrant.

------

The foregoing description of the Warrant does not purport to be complete and is subject in its entirety to the full text of the Warrant, the form of which is filed hereto as Exhibit 4.1.

*Special Committee Approval*

The sale of the Units and the issuance of the Warrant were negotiated and approved by a special committee of the audit committee of the board of directors (the "<u>Board</u>") of the Company consisting solely of disinterested directors. To assist in its evaluation of the transaction, the special committee retained independent legal and financial advisors.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.03. OPAL Fuels Intermediate HoldCo LLC (the "<u>Borrower</u>"), a subsidiary of the Company, prior to the expiration of the delayed draw availability, recently drew down approximately $128.4 million under that certain Credit and Guarantee Agreement, dated September 1, 2023 (as amended by Amendment No. 1 to Credit and Guarantee Agreement, dated March 3, 2025, and as further amended, restated, amended and restated, supplemented or otherwise modified from time to time, the "<u>Credit Agreement</u>"), by and among the Borrower, Bank of America, N.A., as administrative agent, and the financial institutions from time to time parties thereto as lenders and as issuers of letters of credit. The material terms of the Credit Agreement are described in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on March 5, 2025. The Borrower used a portion of net proceeds from the draw down under the Credit Agreement to repay the outstanding balance of approximately $20 million under its revolving loan facility.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02. The Units were offered and sold in reliance upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), and Rule 506 of Regulation D promulgated thereunder. The Units were sold without general solicitation or general advertising to the Investor, which represented that it is an "accredited investor" (within the meaning of Rule 501(a) under the Securities Act). The Units have not been registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

The Units are redeemable at the option of the OPAL Fuels LLC at any time, in whole or in part, at the applicable Redemption Price (as defined in the Amended Series A Certificate of Designations (as defined below)). In addition, the Investor may require mandatory redemption of the Units upon (i) a Change of Control (as defined in the Amended Series A Certificate of Designations), (ii) the occurrence of a Trigger Event (as defined in the Amended Series A Certificate of Designations) that has remained uncured for sixty (60) days, or (iii) at any time on or after the fifth (5th) anniversary of the Original Subscription Date (as defined in the Amended Series A Certificate of Designations), in each case at the applicable Redemption Price. If OPAL Fuels LLC fails to redeem any Units within 90 days of the date on which the Investor requests mandatory redemption, then the Investor will have the right (but not the obligation) to appoint a single director to the Board of the Company.

**Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 5.03. In connection with the Offering and the transactions contemplated by the Subscription Agreement, on March 6, 2026, OPAL Fuels LLC approved and adopted an Amended and Restated Certificate of Designations of Series A Preferred Units (the "<u>Amended Series A Certificate of Designations</u>"). Among other things, the Amended Series A Certificate of Designations increased the dividend rates to 12% per annum (compounding quarterly) with a partial payment-in-kind option, revised the mandatory redemption provisions (including the addition of redemption triggers upon certain events or after the fifth anniversary of the issuance date), added enhanced protective covenants and transfer restrictions, and updated certain other terms and definitions to reflect the current transaction structure.

The foregoing descriptions of the Amended Series A Certificate of Designations do not purport to be complete and are subject to, and qualified in their entirety by reference to, the full text of the Amended Series A Certificate of Designations, copies of which are filed as Exhibit 3.1 to this Current Report on Form 8-K and are incorporated herein by reference.

Section 2. <u>Exercise of Warrant</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Subject to the terms and conditions hereof, this Warrant may be exercised by the holder hereof then registered on the books of the Company, pro rata as hereinafter provided, at any time on any Business Day on or after the opening of business on such Business Day, commencing with the first Business Day immediately following the Issuance Date, and prior to 11:59 P.M. Eastern Time on the Expiration Date (i) by delivery of a written notice, in the form of the exercise notice attached as <u>Exhibit A</u> hereto (the "<u>Exercise Notice</u>"), of such holder's election to exercise this Warrant, which notice shall specify the number of Warrant Shares to be purchased, payment to the Company of an amount equal to the Warrant Exercise Price(s) applicable to the Warrant Shares being purchased, multiplied by the number of Warrant Shares (at the applicable Warrant Exercise Price) as to which this Warrant is being exercised (plus any applicable issue or transfer taxes) (the "<u>Aggregate Exercise Price</u>") in cash or wire transfer of immediately available funds and the surrender of this Warrant (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction) to a common carrier for overnight delivery to the Company as soon as practicable following such date or (ii) by delivering an Exercise Notice and in lieu of making payment of the Aggregate Exercise Price in cash or wire transfer, elect instead to receive upon such exercise the net number of shares of Common Stock determined according to the following formula (the "<u>Cashless Exercise</u>"):

X = Y <u>(A - B)</u> 

A

For purposes of the foregoing formula:

X = the number of Warrant Shares to be issued to the holder.

Y = the total number of Warrant Shares for which the holder has elected to exercise this Warrant pursuant to Section 2(a).

A = the Closing Bid Price of one share of Common Stock on the date of exercise of the Warrant.

B = the Warrant Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event of any exercise of the rights represented by this Warrant in compliance with this Section 2, the Company shall on or before the fifth (5th) Business Day following the date of receipt of the Exercise Notice, the Aggregate Exercise Price and this Warrant (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction) and the receipt of the representations of the holder specified in Section 5 hereof, if requested by the Company (the "<u>Exercise Delivery Documents</u>"), and if the Common Stock is DTC eligible, credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder's or its designee's balance account with The Depository Trust Company; provided, however, if the holder who submitted the Exercise Notice requested physical delivery of any or all of the Warrant Shares, or, if the Common Stock is not DTC eligible then the Company shall, on or before the fifth (5<sup>th</sup>) Business Day following receipt of the Exercise Delivery Documents, issue and surrender to a common carrier for overnight delivery to the address specified in the Exercise Notice, a certificate, registered in the name of the holder, for the number of shares of Common Stock to which the holder shall be entitled pursuant to such request. Upon delivery of the Exercise Notice and Aggregate Exercise Price referred to in clause 2(a)(i) or 2(a)(ii) above, the holder of this Warrant shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised. In the case of a dispute as to the determination of the Warrant Exercise Price, the Closing Bid Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the holder the number of Warrant Shares that is not disputed and shall submit the disputed determinations or arithmetic calculations to the holder via email within one (1) Business Day of receipt of the holder's Exercise Notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Principal Market Limitation</u>. Notwithstanding anything in this Warrant to the contrary, the Company shall not issue any shares of Common Stock pursuant to the terms of this Warrant if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock that the Company may in connection with any transaction aggregated with this Warrant in compliance with the Company's obligations under the rules or regulations of Nasdaq Stock Market, except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Nasdaq Stock Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Unless the rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, as soon as practicable and in no event later than five (5) Business Days after any exercise and at its own expense, issue a new Warrant identical in all respects to this Warrant exercised except it shall represent rights to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant exercised, less the number of Warrant Shares with respect to which such Warrant is exercised.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) <u>No Fractional Shares</u>. No fractional Warrant Shares are to be issued upon any pro rata exercise of this Warrant, but rather the number of Warrant Shares issued upon such exercise of this Warrant shall be rounded up or down to the nearest whole number.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) <u>Forfeiture of Undrawn Warrant Shares</u>. The Additional Warrant Shares are subject to forfeiture if the corresponding Preferred Units are not fully drawn by the end of the Availability Period and OPAL Fuels LLC has proposed a drawdown request for such remaining amount (or a portion thereof) that is not approved by the Holder, but is otherwise permissible under the Subscription Agreement. For the avoidance of doubt, to the extent the Preferred Units are available for drawdown during the Availability Period, but OPAL Fuels LLC elects not to draw down the full amount available, the Holder shall remain entitled to the full amount of Warrant Shares allocable to such undrawn amounts.

Section 3. <u>Covenants as to Common Stock</u>. The Company hereby covenants and agrees as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) This Warrant is, and any Warrants issued in substitution for or replacement of this Warrant will upon issuance be, duly authorized and validly issued.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) All Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) This Warrant will be binding upon any entity succeeding to the Company by merger, consolidation or acquisition of all or substantially all of the Company's assets.

Section 4. <u>Warrant Holder Not Deemed a Stockholder</u>. Except as otherwise specifically provided herein, no holder, as such, of this Warrant shall be entitled to vote or receive dividends or be deemed the holder of shares of capital stock of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the holder hereof, as such, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the holder of this Warrant of the Warrant Shares which he or she is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on such holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

Section 5. <u>Representations of Holder</u>. The holder of this Warrant, by the acceptance hereof, represents that it is acquiring this Warrant and the Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the holder does not agree to hold this Warrant or any of the Warrant Shares for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Shares at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act. The holder of this Warrant further represents, by acceptance hereof, that, as of this date, such holder is an "accredited investor" as such term is defined in Rule 501(a) of Regulation D promulgated by the Securities and Exchange Commission under the Securities Act (an "<u>Accredited Investor</u>"). Upon exercise of this Warrant the holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Warrant Shares so purchased are being acquired solely for the holder's own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale and that such holder is an Accredited Investor. If such holder cannot make such representations because they would be factually incorrect, it shall be a condition to such holder's exercise of this Warrant that the Company receive such other representations as the Company considers reasonably necessary to assure the Company that the issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws.

Section 6. <u>Ownership and Transfer</u>. The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee. The Company may treat the person in whose name any Warrant is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant.

This Warrant shall be freely transferable in whole or in part following the redemption in full of all Preferred Units held by the Holder; provided, that prior to such redemption, this Warrant shall not be transferable without the prior written consent of the Company. No transferee of this Warrant or the Warrant Shares shall enter into or engage in any "short sale" (as defined in Rule 200 of Regulation SHO under the Exchange Act) of, or enter into any hedging or similar transaction with the same economic effect as a "short sale" of, the Common Stock, or engage in any transaction involving the Common Stock for which the purpose is to offset the loss which results from a decline in the market price of the Common Stock, or otherwise establish or increase, directly or indirectly, a put equivalent position, as defined in Rule 16a-1(h) under the Exchange Act, with respect to the Common Stock.

Section 7. <u>Adjustment of Warrant Exercise Price and Number of Shares</u>. The Warrant Exercise Price and the number of shares of Common Stock issuable upon exercise of this Warrant shall be adjusted from time to time as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Adjustment of Warrant Exercise Price upon Subdivision or Combination of Common Stock</u>. If the Company at any time after the date of issuance of this Warrant subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, any Warrant Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock obtainable upon exercise of this Warrant will be proportionately increased. If the Company at any time after the date of issuance of this Warrant combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, any Warrant Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant will be proportionately decreased. Any adjustment under this Section 7(a) shall become effective at the close of business on the date the subdivision or combination becomes effective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Distribution of Assets</u>. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a

dividend, spin off, reclassification, corporate rearrangement or other similar transaction) (a "<u>Distribution</u>"), at any time after the issuance of this Warrant, then, in each such case:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) any Warrant Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Warrant Exercise Price by a fraction of which (A) the numerator shall be the Closing Bid Price of the Common Stock on the trading day immediately preceding such record date minus the value of the Distribution (as determined in good faith by the Company's Board of Directors) applicable to one share of Common Stock, and (B) the denominator shall be the Closing Bid Price of the Common Stock on the trading day immediately preceding such record date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) either (A) the number of Warrant Shares obtainable upon exercise of this Warrant shall be increased to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive the Distribution multiplied by the reciprocal of the fraction set forth in the immediately preceding clause (i), or (B) in the event that the Distribution is of common stock of a company whose common stock is traded on a national securities exchange or a national automated quotation system, then the holder of this Warrant shall receive an additional warrant to purchase Common Stock, the terms of which shall be identical to those of this Warrant, except that such warrant shall be exercisable into the amount of the assets that would have been payable to the holder of this Warrant pursuant to the Distribution had the holder exercised this Warrant immediately prior to such record date and with an exercise price equal to the amount by which the exercise price of this Warrant was decreased with respect to the Distribution pursuant to the terms of the immediately preceding clause (i).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Certain Events</u>. If any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features other than to employees, officers, directors or consultants as compensation), then the Company's Board of Directors will make an appropriate adjustment in the Warrant Exercise Price and the number of shares of Common Stock obtainable upon exercise of this Warrant so as to protect the rights of the holders of the Warrants; provided, except as set forth in Section 7(a), that no such adjustment pursuant to this Section 7(c) will increase the Warrant Exercise Price or decrease the number of shares of Common Stock obtainable as otherwise determined pursuant to this Section 7.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Notices</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Upon any adjustment of the Warrant Exercise Price, the Company will give written notice thereof to the holder of this Warrant, setting forth in reasonable detail, and certifying the calculation of such adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) The Company will give written notice to the holder of this Warrant at least three (3) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution upon the Common Stock, (B) with respect to any pro rata subscription offer to holders of Common Stock or (C) for determining rights to vote with respect to any Organic Change (as defined below), dissolution or liquidation, provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to such holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The Company will also give written notice to the holder of this Warrant at least three (3) days prior to the date on which any Organic Change, dissolution or liquidation will take place, provided that such information shall be made known to the public prior to or in conjunction with such notice being provided to such holder.

Section 8. <u>Purchase Rights; Reorganization, Reclassification, Consolidation, Merger or Sale</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In addition to any adjustments pursuant to Section 7 above, if at any time the Company grants, issues or sells any options, convertible securities or rights to purchase stock, warrants, securities or other property

 -6- <br>

pro rata to the record holders of any class of Common Stock (the "<u>Purchase Rights</u>"), then the holder of this Warrant will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which such holder could have acquired if such holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights. In the event the holder of this Warrant does not exercise any part of this Warrant, the Purchase Rights allocable to such unexercised portion of the Warrant shall be automatically canceled.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Company's assets to another Person or other transaction in each case which is effected in such a way that holders of Common Stock are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock is referred to herein as an "<u>Organic Change</u>". Prior to the consummation of any (i) sale of all or substantially all of the Company's assets to an acquiring Person or (ii) other Organic Change following which the Company is not a surviving entity, the Company will secure from the Person purchasing such assets or the successor resulting from such Organic Change (in each case, the "<u>Acquiring Entity</u>") a written agreement (in form and substance reasonably satisfactory to the holders of Warrants representing at least two-thirds of the Warrant Shares issuable upon exercise of the Warrants then outstanding) to deliver to each holder of Warrants in exchange for such Warrants, a security of the Acquiring Entity evidenced by a written instrument substantially similar in form and substance to this Warrant and reasonably satisfactory to the holders of the Warrants (including an adjusted warrant exercise price equal to the value for the Common Stock reflected by the terms of such consolidation, merger or sale, and exercisable for a corresponding number of shares of Common Stock acquirable and receivable upon exercise of the Warrants without regard to any limitations on exercise, if the value so reflected is less than any applicable Warrant Exercise Price immediately prior to such consolidation, merger or sale). Prior to the consummation of any other Organic Change, the Company shall make appropriate provision (in form and substance reasonably satisfactory to the holders of Warrants representing a majority of the Warrant Shares issuable upon exercise of the Warrants then outstanding) to insure that each of the holders of the Warrants will thereafter have the right to acquire and receive in lieu of or in addition to (as the case may be) the Warrant Shares immediately theretofore issuable and receivable upon the exercise of such holder's Warrants (without regard to any limitations on exercise), such shares of stock, securities or assets that would have been issued or payable in such Organic Change with respect to or in exchange for the number of Warrant Shares which would have been issuable and receivable upon the exercise of such holder's Warrant as of the date of such Organic Change (without taking into account any limitations or restrictions on the exercisability of this Warrant).

Section 9. <u>Lost, Stolen, Mutilated or Destroyed Warrant</u>. If this Warrant is lost, stolen, mutilated or destroyed, the Company shall promptly, on receipt of an indemnification undertaking (or, in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed.

Section 10. <u>Notice</u>. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by email (provided confirmation of receipt is received by the sending party); or (iii) one Business Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed to the party to receive the same.

Section 11. <u>Date</u>. The date of this Warrant is set forth on page 1 hereof. This Warrant, in all events, shall be wholly-void and of no effect after the close of business on the Expiration Date.

Section 12. <u>Amendment and Waiver</u>. Except as otherwise provided herein, the provisions of the Warrants may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder; provided that, except for Section 7(a), no such action may increase the Warrant Exercise Price or decrease the number of shares or class of stock obtainable upon exercise of any Warrant without the written consent of the Holder.

In the event of such objection, the Investor shall have the right to designate an alternative replacement, subject to the same review process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.3**Ceases to Serve**.

7.**Governing Law.** This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the conflict of laws principles thereof. Each Party irrevocably submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or, if the Court of Chancery declines to accept jurisdiction, any state or federal court sitting in the State of Delaware) for the adjudication of any dispute arising out of or relating to this Agreement.

10.**Severability**.
