RECITALS

     A. Concurrently with the execution of this Agreement, the Company and the Investors that are holders of the Class A Common Stock are entering into a Class A Common Stock Purchase Agreement (the “Purchase Agreement”) providing for the issuance of shares of the Class A Common Stock.

     B. Concurrently with the execution of this Agreement, the Company and the Investors that are holders of the Class B Common Stock are entering into a Debt Conversion Agreement (the “Conversion Agreement”) providing for the issuance of shares of the Class B Common Stock.

     C. In connection with the entering into of the Purchase Agreement and the Conversion Agreement, the parties desire to provide the Investors with the right, among other rights, to designate the election of certain members of the Board of Directors of the Company (the “Board”) in accordance with the terms of this Agreement.

     D. The Amended and Restated Certificate of Incorporation of the Company (the “Restated Certificate”) provides that: (a) the holders of record of the shares of the Class A Common Stock, exclusively and as a separate class, shall be entitled to elect three (3) directors of the Company (the “Class A Common Directors”); (b) the holders of record of the shares of Class B Common Stock, exclusively and as a separate class, shall be entitled to elect three (3) directors of the Company (the “Class B Common Directors”); and (c) the holders of record of the shares of the Class A Common Stock and the Class B Common Stock, voting together as a separate class, shall be entitled to elect one (1) director of the Company (the “Independent Director”).

     E. The parties also desire to enter into this Agreement to set forth their agreements and understandings with respect to how shares of the Company’s capital stock held by them will be voted on or tendered in connection with (i) an acquisition of the Company and (ii) the authorization of additional shares of Common Stock of the Company.

     NOW, THEREFORE, the parties agree as follows:

     1. Voting Provisions Regarding Board of Directors.

          1.1 Size of the Board. Each Stockholder agrees to vote, or cause to be voted, all Shares (as defined below) owned by such Stockholder, or over which such Stockholder has voting control, from time to time and at all times, in whatever manner as shall be necessary to ensure that the size of the Board shall be set and remain at seven (7) directors and may be increased or decreased only with the prior written consent of (a) PTT Chemical International Private Limited (“PTTCH”) or (b) the approval of the Board, including the affirmative vote of at least one (1) Class A Common Director designated by PTTCH. For purposes of this Agreement, the term “Shares” shall mean and include any

securities of the Company the holders of which are entitled to vote for election of directors, including without limitation, all shares of Common Stock, Class A Common Stock, and Class B Common Stock, by whatever name called, now owned or subsequently acquired by a Stockholder, however acquired, whether through stock splits, stock dividends, reclassifications, recapitalizations, similar events or otherwise.

          1.2 Board Composition. Each Stockholder agrees to vote, or cause to be voted (to the extent so entitled), all Shares owned by such Stockholder, or over which such Stockholder has voting control, from time to time and at all times, in whatever manner as shall be necessary to ensure that at each annual or special meeting of stockholders at which an election of directors is held or pursuant to any written consent of the stockholders, the following persons shall be elected to the Board:

               (a) Three (3) persons designated by PTTCH (the “PTTCH Designees”) as the Class A Common Directors, for so long as such Stockholder and its Affiliates continue to own beneficially at least ten percent (10%) of the number of shares of Class A Common Stock it acquires pursuant to the Purchase Agreement (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Class A Common Stock), which individuals will initially be Puntip Oungpasuk, Narongsak Jivakanun and Thitipong Jurapornsiridee;

               (b) One (1) person designated by Norwood LDK, LLC (the “Norwood Designee”), for so long as such Stockholder and its Affiliates continue to own beneficially at least ten percent (10%) of the number of shares of Class B Common Stock it acquires pursuant to the Conversion Agreement (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Class B Common Stock), which individual will initially be Stephen J. Gatto;

               (c) One (1) person designated by Plainfield Direct LLC (the “Plainfield Designee”), for so long as such Stockholder and its Affiliates continue to own beneficially at least ten percent (10%) of the number of shares of Class B Common Stock it acquires pursuant to the Conversion Agreement (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Class B Common Stock), which individual will initially be Keith Carter;

               (d) One (1) person designated by Green Chem Second Edition, LLC (the “Green Chem Designee”), for so long as such Stockholder and its Affiliates continue to own beneficially at least ten percent (10%) of the number of shares of Class B Common Stock it acquires pursuant to the Conversion Agreement (subject to appropriate adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization with respect to the Class B Common Stock), which individual will initially be Steven M. Sisselman; and

               (e) One (1) person as the Independent Director who will be an individual not otherwise an Affiliate of the Company who is mutually acceptable to and nominated by PTTCH, on the one hand, and Norwood LDK, LLC, Plainfield Direct LLC and Green Chem Second Edition, LLC, on the other hand, and who shall have the appropriate expertise and experience in the relevant industry that can enhance the business of the Company.

     To the extent that any of clauses (a) through (e) above shall not be applicable, any member of the Board who would otherwise have been designated in accordance with the terms thereof shall instead be voted upon by all the stockholders of the Company entitled to vote thereon in accordance with, and pursuant to, the Company’s Restated Certificate.

For purposes of this Agreement, an individual, firm, corporation, partnership, association, limited liability company, trust or any other entity (collectively, a “Person”) shall be deemed an "Affiliate” of another Person who, directly or indirectly, controls, is controlled by or is under common control with such Person, including, without limitation, any general partner, managing member, officer or director of such Person or any venture capital fund now or hereafter existing that is controlled by one or more general partners or managing members of, or shares the same management company with, such Person.

          1.3 Failure to Designate a Board Member. In the absence of any designation from the Persons or groups with the right to designate a director as specified above, the director previously designated by them and then serving shall be reelected if still eligible to serve as provided herein.

          1.4 Removal of Board Members. Each Stockholder also agrees to vote, or cause to be voted (to the extent so entitled), all Shares owned by such Stockholder, or over which such Stockholder has voting control, from time to time and at all times, in whatever manner as shall be necessary to ensure that:

               (a) no director elected pursuant to Subsections 1.2 or 1.3 of this Agreement may be removed from office other than for cause unless (i) such removal is directed or approved by the affirmative vote of the Person, or of the holders of at least a majority of the shares of stock, entitled under Subsection 1.2 to designate that director or (ii) the Person(s) originally entitled to designate or approve such director or occupy such Board seat pursuant to Subsection 1.2 is no longer so entitled to designate or approve such director or occupy such Board seat;

               (b) any vacancies created by the resignation, removal or death of a director elected pursuant to Subsections 1.2 or 1.3 shall be filled pursuant to the provisions of this Section 1;

               (c) upon the request of any party entitled to designate a director as provided in Subsection 1.2(a) or 1.2(b) to remove such director, such director shall be removed; and

               (d) All Stockholders agree to execute any written consents required to perform the obligations of this Agreement, and the Company agrees at the request of any party entitled to designate directors to call a special meeting of stockholders for the purpose of electing directors.

          1.5 No Liability for Election of Recommended Directors. No Stockholder, nor any Affiliate of any Stockholder, shall have any liability as a result of designating a person for election as a director for any act or omission by such designated person in his or her capacity as a director of the Company, nor shall any Stockholder have any liability as a result of voting for any such designee in accordance with the provisions of this Agreement.

     2. Vote to Increase Authorized Common Stock. Each Stockholder agrees to vote or cause to be voted all Shares owned by such Stockholder, or over which such Stockholder has voting control, from time to time and at all times, in whatever manner as shall be necessary to increase the number of authorized shares of Common Stock from time to time to ensure that there will be sufficient shares of Common Stock available for conversion of all of the shares of Class A Common Stock and Class B Common Stock outstanding at any given time.

     3. Drag-Along Right.

          3.1 Definitions. A “Sale of the Company” shall mean a transaction that qualifies as a “Deemed Liquidation Event” as defined in the Restated Certificate.

          3.2 Actions to be Taken. In the event that (i) at least a majority of the Board (including at least two of the Class A Common Directors designated by PTTCH and at least two of the Class B Common Directors) and (ii) the holders of at least a majority of the Class A Common Stock and Class B Common Stock held by the Investors (including PTTCH) approve a Sale of the Company in writing, specifying that this Section 3 shall apply to such transaction, then each Stockholder hereby agrees:

          (a) if such transaction requires stockholder approval, with respect to all Shares that such Stockholder owns or over which such Stockholder otherwise exercises voting power, to vote (in person, by proxy or by action by written consent, as applicable) all Shares in favor of, and adopt, such Sale of the Company (together with any related amendment to the Restated Certificate required in order to implement such Sale of the Company) and to vote in opposition to any and all other proposals that could reasonably be expected to delay or impair the ability of the Company to consummate such Sale of the Company;

          (b) to execute and deliver all related documentation and take such other action in support of the Sale of the Company as shall reasonably be requested by the Company or the selling Investors in order to carry out the terms and provisions of this Section 3, including without limitation executing and delivering instruments of conveyance and transfer, and any purchase agreement, merger agreement, indemnity agreement, escrow agreement, consent, waiver, governmental filing, share certificates duly endorsed for transfer (free and clear of impermissible liens, claims and encumbrances) and any similar or related documents;

          (c) not to deposit, and to cause their Affiliates not to deposit, except as provided in this Agreement, any Shares of the Company owned by such party or Affiliate in a voting trust or subject any Shares to any arrangement or agreement with respect to the voting of such Shares, unless specifically requested to do so by the acquiror in connection with the Sale of the Company;

          (d) to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time with respect to such Sale of the Company; and

          (e) if the consideration to be paid in exchange for the Shares pursuant to this Section 3 includes any securities and due receipt thereof by any Stockholder would require under applicable law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities or (y) the provision to any Stockholder of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act of 1933, as amended, the Company may cause to be paid to any such Stockholder in lieu thereof, against surrender of the Shares which would have otherwise been sold by such Stockholder, an amount in cash equal to the fair value (as determined in good faith by the Company) of the securities which such Stockholder would otherwise receive as of the date of the issuance of such securities in exchange for the Shares.

          3.3 Exceptions. Notwithstanding the foregoing, a Stockholder will not be required to comply with Subsection 3.2 above in connection with any proposed Sale of the Company (the “Proposed Sale”) unless:

               (a) the liability for indemnification, if any, of such Stockholder in the Proposed Sale and for the inaccuracy of any representations and warranties made by the Company or its Stockholders in connection with such Proposed Sale, is several and not joint with any other Person (except to the extent that funds may be paid out of an escrow established to cover breach of representations, warranties and covenants of the Company as well as breach by any stockholder of any of

identical representations, warranties and covenants provided by all stockholders), and is pro rata in proportion to, and does not exceed, the amount of consideration paid to such Stockholder in connection with such Proposed Sale;

               (b) upon the consummation of the Proposed Sale, (A) each holder of each class or series of the Company’s stock will receive the same form of consideration for their shares of such class or series as is received by other holders in respect of their Shares of such same class or series of stock and (B) each holder of a class of Common Stock will receive the same amount of consideration per share of such class of Common Stock as is received by other holders in respect of their Shares of such same class; provided, however, that, notwithstanding the foregoing, if the consideration to be paid in exchange for the Shares pursuant to this Section 3 includes any securities and due receipt thereof by any Stockholder would require under applicable law (x) the registration or qualification of such securities or of any person as a broker or dealer or agent with respect to such securities or (y) the provision to any Stockholder of any information other than such information as a prudent issuer would generally furnish in an offering made solely to “accredited investors” as defined in Regulation D promulgated under the Securities Act of 1933, as amended, the Company may cause to be paid to any such Stockholder in lieu thereof, against surrender of the Shares which would have otherwise been sold by such Stockholder, an amount in cash equal to the fair value (as determined in good faith by the Company) of the securities which such Stockholder would otherwise receive as of the date of the issuance of such securities in exchange for the Shares; and

               (c) subject to clause (b) above, requiring the same form of consideration to be available to the holders of any single class or series of capital stock, if any holders of any capital stock of the Company are given an option as to the form and amount of consideration to be received as a result of the Proposed Sale, all holders of such capital stock will be given the same option; provided, however, that nothing in this Subsection 3.3(c) shall entitle any Stockholder to receive any form of consideration that such Stockholder would be ineligible to receive as a result of such Stockholder’s failure to satisfy any condition, requirement or limitation that is generally applicable to the Company’s stockholders.

     4. Remedies.

          4.1 Covenants of the Company. The Company agrees to use its best efforts, within the requirements of applicable law, to ensure that the rights granted under this Agreement are effective and that the parties enjoy the benefits of this Agreement.

          4.2 Specific Enforcement. Each party acknowledges and agrees that each party hereto will be irreparably damaged in the event any of the provisions of this Agreement are not performed by the parties in accordance with their specific terms or are otherwise breached. Accordingly, it is agreed that each of the Company and the Stockholders shall be entitled to seek an injunction to prevent breaches of this Agreement, and to seek specific enforcement of this Agreement and its terms and provisions in any action instituted in any court of the United States or any state having subject matter jurisdiction.

plan or an SEC Rule 145 transaction); (b) the occurrence of a “Deemed Liquidation Event” as defined in the Restated Certificate; and (c) termination of this Agreement in accordance with Subsection 6.8 below.

In such case, Schedule A hereto may be amended by the Company to add such person without the consent of the other parties hereto.

               (b) In the event that after the date of this Agreement, the Company enters into an agreement with any Person to issue shares of capital stock to such Person (other than to a purchaser of Class A Common Stock or Class B Common Stock described in Subsection 6.1(a) above), following which such Person shall hold Shares constituting one percent (1%) or more of the Company’s then outstanding capital stock (treating for this purpose all shares of Common Stock issuable upon exercise of or conversion of outstanding options, warrants or convertible securities, as if exercised and/or converted or exchanged), then the Company shall cause such Person, as a condition precedent to entering into such agreement, to become a party to this Agreement by executing an Adoption Agreement in the form attached hereto as Exhibit A, agreeing to be bound by and subject to the terms of this Agreement as a Key Common Holder and thereafter such person shall be deemed a Key Common Holder for all purposes under this Agreement.

Upon the execution and delivery of an Adoption Agreement by any transferee, such transferee shall be deemed to be a party hereto as if such transferee were the transferor and such transferee’s signature appeared on the signature pages of this Agreement and shall be deemed to be an Investor and Stockholder, or Key Common Holder and Stockholder, as applicable. The Company shall not permit the transfer of the Shares subject to this Agreement on its books or issue a new certificate representing any such Shares unless and until such transferee shall have complied with the terms of this Subsection 6.2.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Notwithstanding the foregoing:

               (a) this Agreement may not be amended or terminated and the observance of any term of this Agreement may not be waived with respect to any Key Common Holder without the written consent of such Key Common Holder unless such amendment, termination or waiver applies to all Key Common Holders in the same fashion;

               (b) the consent of the Key Common Holders shall not be required for any amendment or waiver if such amendment or waiver either (A) is not directly applicable to the rights of the Key Common Holders hereunder or (B) does not adversely affect the rights of the Key Common Holders in a manner that is different than the effect on the rights of the other parties hereto;

               (c) Schedule A and Schedule B hereto may be amended by the Company from time to time in accordance with Subsection 6.1 to add information regarding additional parties without the consent of the other parties hereto;

For purposes of this Subsection 6.8, the requirement of a written instrument may be satisfied in the form of an action by written consent of the Stockholders circulated by the Company and executed by the Stockholder parties specified, whether or not such action by written consent makes explicit reference to the terms of this Agreement.

          6.9 Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default previously or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing.

          6.10 Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision.

          6.12 Legend on Share Certificates. Each certificate representing any Shares issued after the date hereof shall be endorsed by the Company with a legend reading substantially as follows:

“THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A VOTING AGREEMENT, AS MAY BE AMENDED FROM TIME TO TIME, (A COPY OF WHICH MAY BE OBTAINED UPON WRITTEN REQUEST FROM THE COMPANY), AND BY ACCEPTING ANY INTEREST IN SUCH SHARES THE PERSON ACCEPTING SUCH INTEREST SHALL BE DEEMED TO AGREE TO AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF THAT VOTING AGREEMENT, INCLUDING CERTAIN RESTRICTIONS ON TRANSFER AND OWNERSHIP SET FORTH THEREIN.”

The Company, by its execution of this Agreement, agrees that it will cause the certificates evidencing the Shares issued after the date hereof to bear the legend required by this Subsection 6.12, and it shall supply, free of charge, a copy of this Agreement to any holder of a certificate evidencing Shares upon written request from such holder to the Company at its principal office. The parties to this Agreement do hereby agree that the failure to cause the certificates evidencing the Shares to bear the legend required by this Subsection 6.12 herein and/or the failure of the Company to supply, free of charge, a copy of this Agreement as provided hereunder shall not affect the validity or enforcement of this Agreement.

          6.13 Stock Splits, Stock Dividends, etc. In the event of any issuance of Shares of the Company’s voting securities hereafter to any of the Stockholders (including, without limitation, in connection with any stock split, stock dividend, recapitalization, reorganization, or the like), such Shares shall become subject to this Agreement and shall be endorsed with the legend set forth in Subsection 6.12.

          6.14 Manner of Voting. The voting of Shares pursuant to this Agreement may be effected in person, by proxy, by written consent or in any other manner permitted by applicable law.

There shall be one (1) arbitrator mutually agreed upon by the parties from the names of potential arbitrators proposed by the AAA. If no agreement on the sole arbitrator can be reached within thirty (30) days after names of potential arbitrators have been proposed by the AAA, then the AAA shall select the sole arbitrator, who shall have at least ten (10) years experience in corporate finance transactions of the type provided for in this Agreement. The arbitration shall take place in New York, New York, and any award shall be final and binding and judgment thereon may be entered in any court having jurisdiction thereof.
