iv AGREEMENT AND PLAN OF MERGER This AGREEMENT AND PLAN OF MERGER, dated as of March 8, 2005 (this "Agreement"), is among CROMPTON CORPORATION, a Delaware corporation ("Crompton"), COPERNICUS MERGER CORPORATION, a Delaware corporation and a direct, wholly owned Subsidiary of Crompton ("Merger Sub"), and GREAT LAKES CHEMICAL CORPORATION, a Delaware corporation ("Great Lakes"). Certain terms used in this Agreement are defined in Section 9.8. WHEREAS, the respective Boards of Directors of Crompton, Merger Sub and Great Lakes have approved and declared advisable this Agreement and the merger of Merger Sub with and into Great Lakes (the "Merger"), on the terms and subject to the conditions provided for in this Agreement, in order to advance the long-term strategic business interests of Crompton and Great Lakes; and WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the "Code"), and that this Agreement constitutes a plan of reorganization. NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Agreement, and intending to be legally bound hereby, Crompton, Merger Sub and Great Lakes hereby agree as follows: ARTICLE I The Merger SECTION 1.1. The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the General Corporation Law of the State of Delaware (the "DGCL"), at the Effective Time, Merger Sub shall be merged with and into Great Lakes, and the separate corporate existence of Merger Sub shall thereupon cease, and Great Lakes shall be the surviving corporation in the Merger (the "Surviving Corporation"). SECTION 1.2. Closing. The closing of the Merger (the "Closing") shall take place at 10:00 a.m. (New York City time) on a date to be specified by the parties (the "Closing Date"), which date shall be no later than the second Business Day after satisfaction or waiver of the conditions set forth in Article VII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions at such time), at the offices of Weil, Gotshal & Manges LLP, 767 Fifth Avenue, New York, New York 10153, unless another time, date or place is agreed to in writing by the parties hereto. SECTION 1.3. Effective Time. Subject to the provisions of this Agreement, as soon as practicable on the Closing Date, the parties shall file with the Secretary of State of the State of Delaware a certificate of merger, executed in accordance with the relevant provisions of the DGCL (the "Certificate of Merger"). The Merger shall become effective upon the filing of the Certificate of Merger or at such later time as is agreed to by the parties hereto and specified in the Certificate of Merger (the time at which the Merger becomes effective is herein referred to as the "Effective Time"). 2 SECTION 1.4. Effects of the Merger. The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of Great Lakes and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Great Lakes and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation. SECTION 1.5. Certificate of Incorporation and By-laws of the Surviving Corporation. (a) The Restated Certificate of Incorporation of Great Lakes, as in effect immediately prior to the Effective Time, shall be amended in the Merger to be in the form of Exhibit A and, as so amended, such certificate of incorporation shall be the certificate of incorporation of the Surviving Corporation until thereafter amended as provided therein or by applicable Law. (b) The by-laws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the by-laws of the Surviving Corporation until thereafter amended as provided therein or by applicable Law. SECTION 1.6. Directors of the Surviving Corporation. Each of the parties hereto shall take all necessary action to cause the directors of Merger Sub immediately prior to the Effective Time to be the directors of the Surviving Corporation immediately following the Effective Time, until their respective successors are duly elected or appointed and qualified or their earlier death, resignation or removal in accordance with the certificate of incorporation and by-laws of the Surviving Corporation. ARTICLE II Effect of the Merger on the Capital Stock of the ------------------------------------------------ Constituent Corporations; Exchange of Certificates; Great Lakes Stock Options, ------------------------------------------------------------------------------ Great Lakes Restricted Share Units and Great Lakes Restricted Shares -------------------------------------------------------------------- SECTION 2.1. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of common stock, par value $1.00 per share, of Great Lakes ("Great Lakes Common Stock") or any shares of capital stock of Merger Sub: (a) Capital Stock of Merger Sub. Each issued and outstanding share of capital stock of Merger Sub shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation. 3 (b) Cancellation of Treasury Stock and Crompton-Owned Stock. Any shares of Great Lakes Common Stock that are owned by Great Lakes as treasury stock, and any shares of Great Lakes Common Stock owned by Crompton or Merger Sub, shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange therefor. (c) Conversion of Great Lakes Common Stock. Subject to Section 2.2(e), each issued and outstanding share of Great Lakes Common Stock (other than shares to be canceled in accordance with Section 2.1(b)) shall be converted into the right to receive 2.2232 (the "Exchange Ratio") validly issued, fully paid and nonassessable shares of common stock, par value $0.01 per share, of Crompton ("Crompton Common Stock") (the "Merger Consideration"). As of the Effective Time, all such shares of Great Lakes Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate which immediately prior to the Effective Time represented any such shares of Great Lakes Common Stock (each, a "Certificate") shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c) and any net cash proceeds from the sale of the Excess Shares to which such holder is entitled pursuant to Section 2.2(e), in each case to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.2(b), without interest. SECTION 2.2. Exchange of Certificates. (a) Exchange Agent. As of the Effective Time, Crompton shall deposit with the bank or trust company to be designated by Crompton and reasonably acceptable to Great Lakes (the "Exchange Agent"), for exchange in accordance with this Article II, through the Exchange Agent, certificates representing the shares of Crompton Common Stock issuable pursuant to Section 2.1 in exchange for outstanding shares of Great Lakes Common Stock (such shares of Crompton Common Stock, together with any dividends or other distributions with respect thereto with a record date after the Effective Time, being hereinafter referred to as the "Exchange Fund"). (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, Crompton shall cause the Exchange Agent to mail to each holder of record of a Certificate whose shares of Great Lakes Common Stock were converted pursuant to Section 2.1(c) into the right to receive the Merger Consideration, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent, and which shall be in such form as Crompton and Great Lakes may reasonably agree to use and shall have such other provisions as Crompton and Great Lakes may reasonably agree to specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing the Merger Consideration, any dividends or other distributions to which holders of Certificates are entitled pursuant to Section 2.2(c) and any net cash proceeds from the sale of the Excess Shares to which such holders are entitled pursuant to Section 2.2(e). Upon surrender of a Certificate for cancellation to the Exchange Agent, together 4 with such letter of transmittal, duly completed and validly executed in accordance with the instructions (and such other customary documents as may reasonably be required by the Exchange Agent), the holder of such Certificate shall be entitled to receive in exchange therefor (A) a certificate representing that number of whole shares of Crompton Common Stock that such holder has the right to receive pursuant to the provisions of this Article II after taking into account all the shares of Great Lakes Common Stock then held by such holder under all such Certificates so surrendered, (B) any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c) and (C) any net cash proceeds from the sale of the Excess Shares to which such holder is entitled pursuant to Section 2.2(e), and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of shares of Great Lakes Common Stock that is not registered in the transfer records of Great Lakes, a certificate representing the proper number of shares of Crompton Common Stock may be issued to a Person other than the Person in whose name the Certificate so surrendered is registered, if, upon presentation to the Exchange Agent, such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer and the Person requesting such issuance shall have paid, or pay, any transfer and other taxes required by reason of the issuance of shares of Crompton Common Stock to a Person other than the registered holder of such Certificate or shall have established to the reasonable satisfaction of Crompton and the Exchange Agent that such tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration, any dividends or other distributions to which the holder of such Certificate is entitled pursuant to Section 2.2(c) and any net cash proceeds from the sale of the Excess Shares to which such holder is entitled pursuant to Section 2.2(e), in each case without interest. (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Crompton Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Crompton Common Stock that the holder thereof has the right to receive upon the surrender thereof, and no cash payment in lieu of any fractional shares of Crompton Common Stock shall be paid to any such holder pursuant to Section 2.2(e), in each case until the holder of such Certificate shall surrender such Certificate in accordance with this Article II. Following surrender of any Certificate in accordance with this Article II, there shall be paid to the record holder thereof, without interest, (i) at the time of such surrender, the amount of any net cash proceeds from the sale of the Excess Shares to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions, payable with respect to that number of whole shares of Crompton Common Stock issuable in exchange for such Certificate pursuant to this Article II, with a record date after the Effective Time and paid with respect to Crompton Common Stock prior to such surrender, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Crompton Common Stock. 5 (d) Transfer Books; No Further Ownership Rights in Great Lakes Stock. All shares of Crompton Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms of this Article II (including any dividends or other distributions paid pursuant to Section 2.2(c) and any net cash proceeds from the sale of the Excess Shares paid pursuant to Section 2.2(e)) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Great Lakes Common Stock previously represented by such Certificates, and at the close of business on the day on which the Effective Time occurs, the stock transfer books of Great Lakes shall be closed and thereafter there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Great Lakes Common Stock that were outstanding immediately prior to the Effective Time. Subject to the last sentence of Section 2.2(g), if, at any time after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article II. (e) No Fractional Shares. No certificates or scrip representing fractional shares of Crompton Common Stock shall be issued upon the surrender for exchange of Certificates, no dividends or other distributions of Crompton shall relate to such fractional share interests and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Crompton. In lieu of such fractional share interests, each holder of a Certificate shall receive (upon surrender thereof as provided in this Article II) an amount in cash (without interest) equal to such holder's proportionate interest in the net proceeds from the sale or sales by the Exchange Agent in accordance with the provisions of this Section 2.2(e), on behalf of all such holders, of the Excess Shares. As soon as reasonably practicable following the Effective Time, the Exchange Agent shall determine the excess of (A) the aggregate number of shares of Crompton Common Stock into which the shares of Great Lakes Common Stock were converted pursuant to Section 2.1(c) before giving effect to the first sentence of this Section 2.2(e) over (B) the aggregate number of whole shares of Crompton Common Stock to which the former holders of shares of Great Lakes Common Stock are entitled pursuant to Section 2.1(c) after giving effect to the first sentence of this Section 2.2(e) (such excess, the "Excess Shares"). As soon as reasonably practicable after the Effective Time, the Exchange Agent, as agent for the holders of the Certificates, shall sell the Excess Shares at the then-prevailing prices on the New York Stock Exchange. The sale of the Excess Shares on the New York Stock Exchange shall be executed through one or more member firms of the New York Stock Exchange and shall be executed in round lots to the extent practicable. The Exchange Agent shall deduct from the proceeds of sale of the Excess Shares all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent, incurred in connection with such sale of the Excess Shares. Until the net proceeds of such sale of the Excess Shares have been distributed to the holders of Certificates, the Exchange Agent will hold such net proceeds in trust for such holders of Certificates (the "Excess Shares Trust"). The portion of the Excess Shares Trust to which each holder of a Certificate shall be entitled, if any, shall be determined by multiplying the amount of the aggregate net proceeds comprising the Excess Shares Trust by a fraction, the numerator of which is the amount of the fractional share interest in Crompton Common Stock to which such holder of a Certificate is entitled and the denominator of which is the aggregate amount of fractional share interests in Crompton Common Stock to which all holders of Certificates are entitled. Crompton shall comply with the provisions of Rule 236(c) under the Securities Act in connection with such sale of the Excess Shares. 6 (f) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Crompton, the posting by such Person of a bond, in such reasonable amount as Crompton may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration, any dividends or other distributions to which the holder of such Certificate would be entitled pursuant to Section 2.2(c) and any net cash proceeds from the sale of the Excess Shares to which such holder would be entitled pursuant to Section 2.2(e), in each case pursuant to this Agreement. (g) Termination of the Exchange Fund and the Excess Shares Trust. Any portion of the Exchange Fund or the Excess Shares Trust that remains undistributed to the holders of the Certificates for one year after the Effective Time shall be delivered to Crompton, upon demand, and any holders of Certificates who have not theretofore complied with this Article II shall thereafter look only to Crompton for payment of their claim for the Merger Consideration, any dividends or other distributions with respect to shares of Crompton Common Stock and any net cash proceeds from the sale of the Excess Shares in accordance with this Article II. If any Certificate shall not have been surrendered immediately prior to such date on which any Merger Consideration (and all dividends or other distributions payable pursuant to Section 2.2(c) and all net cash proceeds from the sale of the Excess Shares payable pursuant to Section 2.2(e)) would otherwise escheat to or become property of any Governmental Authority, any such Merger Consideration (and all dividends or other distributions payable pursuant to Section 2.2(c) and all net cash proceeds from the sale of the Excess Shares payable pursuant to Section 2.2(e)) shall become, to the extent permitted by applicable Law, the property of Crompton, free and clear of all claims or interest of any Person previously entitled thereto. (h) No Liability. Notwithstanding any provision of this Agreement to the contrary, none of the parties hereto, the Surviving Corporation or the Exchange Agent shall be liable to any Person in respect of any shares of Crompton Common Stock (or dividends or other distributions with respect thereto) or cash from the Exchange Fund or the Excess Shares Trust, in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. (i) Investment of the Exchange Fund and the Excess Shares Trust. The Exchange Agent shall invest any cash included in the Exchange Fund or the Excess Shares Trust, as directed by Crompton. Any interest and other income resulting from such investments shall be the property of, and shall be paid to, Crompton. (j) Withholding Taxes. Crompton and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable to a holder of shares of Great Lakes Common Stock, Great Lakes Stock Options, Great Lakes Restricted Share Units or Great Lakes Restricted Shares pursuant to this 7 Agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Code, or under any provision of state, local or foreign tax Law. To the extent amounts are so withheld and paid over to the appropriate taxing authority, Crompton and the Exchange Agent shall be treated as though they withheld from the type of consideration from which withholding is required, an appropriate amount otherwise payable pursuant to this Agreement to any holder of shares of Great Lakes Common Stock, Great Lakes Stock Options, Great Lakes Restricted Share Units or Great Lakes Restricted Shares in order to provide for such withholding obligation and such withheld amounts shall be treated for the purposes of this Agreement as having been paid to the former holder of the shares of Great Lakes Common Stock, Great Lakes Stock Options, Great Lakes Restricted Share Units or Great Lakes Restricted Shares. If withholding is required from shares of Crompton Common Stock, Crompton and the Exchange Agent shall be treated as having sold such consideration for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate taxing authority. SECTION 2.3. Great Lakes Stock Options, Great Lakes Restricted Share Units and Great Lakes Restricted Shares. (a) Great Lakes Stock Options. Before the Closing, the Board of Directors of Great Lakes (or, if appropriate, any committee of the Board of Directors of Great Lakes administering the Great Lakes Stock Plans) shall adopt such resolutions or take such other actions as may be required to effect the following: (i) adjust the terms of all outstanding options to acquire shares of Great Lakes Common Stock (each, a "Great Lakes Stock Option") granted under Great Lakes' 2002 Stock Option and Incentive Plan, 1998 Stock Compensation Plan, as amended, 1993 Employee Stock Compensation Plan, as amended, and 1984 Employee Stock Option Plan, as amended (collectively, the "Great Lakes Stock Plans"), whether vested or unvested, as necessary to provide that, at the Effective Time, each Great Lakes Stock Option outstanding immediately prior to the Effective Time shall be amended and converted into an option to acquire, on the same terms and conditions as were applicable under the corresponding Great Lakes Stock Option (taking into account the terms of the Great Lakes Stock Plans, the individual award agreement pursuant to which the Great Lakes Stock Option was granted and any individual agreement providing for vesting of such Great Lakes Stock Option upon a change in control of Great Lakes), that number of shares of Crompton Common Stock (rounded down to the nearest whole share) determined by multiplying the number of shares of Great Lakes Common Stock subject to such Great Lakes Stock Option by the Exchange Ratio, at a price per share of Crompton Common Stock equal to (A) the exercise price per share of Great Lakes Common Stock otherwise purchasable pursuant to such Great Lakes Stock Option divided by (B) the Exchange Ratio (each Great Lakes Stock Option, as so adjusted, an "Adjusted Great Lakes Stock Option"), provided that the exercise price of the Adjusted Great Lakes Stock Option shall be rounded up to the nearest whole cent; and 8 (ii) make such other changes to the Great Lakes Stock Plans as Crompton and Great Lakes may agree are appropriate to give effect to the Merger. (b) Great Lakes Restricted Share Units. Before the Closing, the Board of Directors of Great Lakes (or, if appropriate, any committee of the Board of Directors of Great Lakes administering the Great Lakes Stock Plans) shall adopt such resolutions or take such other actions as may be required to adjust the terms of all outstanding restricted share units granted under the Great Lakes Stock Plans (each, a "Great Lakes Restricted Share Unit"), whether vested or unvested, as necessary to provide that, at the Effective Time, each Great Lakes Restricted Share Unit outstanding immediately prior to the Effective Time shall be amended and converted into a restricted share unit to receive, on the same terms and conditions as were applicable under the Great Lakes Restricted Share Unit (taking into account the terms of the Great Lakes Stock Plans, the individual award agreement pursuant to which the Great Lakes Restricted Share Unit was granted and any individual agreement providing for the vesting of such Great Lakes Restricted Share Unit upon a change in control of Great Lakes), that number of shares of Crompton Common Stock (rounded down to the nearest whole share) determined by multiplying the number of shares of Great Lakes Common Stock subject to such corresponding Great Lakes Restricted Share Unit by the Exchange Ratio (each Great Lakes Restricted Share Unit, as so adjusted, an "Adjusted Great Lakes Restricted Share Unit"). (c) Great Lakes Restricted Shares. At the Effective Time, each share of Great Lakes Common Stock (other than any shares to be cancelled in accordance with Section 2.1(b)) which is subject to restrictions or forfeiture risks ("Great Lakes Restricted Shares") shall be converted to that number of shares of Crompton Common Stock ("Adjusted Great Lakes Restricted Shares") as the holder of such Great Lakes Restricted Share would have been entitled to receive pursuant to the Merger had the Great Lakes Restricted Share not been subject to restrictions or forfeiture risks immediately prior to the Effective Time, which Adjusted Great Lakes Restricted Share shall be subject to the same restrictions and forfeiture risks as applied to the corresponding Great Lakes Restricted Share. (d) The adjustments provided herein with respect to any Great Lakes Stock Options that are "incentive stock options" as defined in Section 422 of the Code shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code and the adjustments provided herein with respect to any Great Lakes Stock Options, Great Lakes Restricted Share Units and Great Lakes Restricted Shares shall be made in accordance with the requirements of Section 409A of the Code (or a good faith interpretation thereof in the absence of definitive guidance thereunder). (e) At the Effective Time, by virtue of the Merger and without the need of any further corporate action, Crompton shall assume the Great Lakes Stock Plans, with the result that all obligations of Great Lakes under the Great Lakes Stock Plans, including with respect to Great Lakes Stock Options, Great Lakes Restricted Share Units and Great Lakes Restricted Shares outstanding at 9 the Effective Time (adjusted pursuant to Sections 2.3(a), (b) and (c)), shall be obligations of Crompton following the Effective Time. As of and after the Effective Time, the Board of Directors of Crompton, or any committee thereof responsible for the administration of stock plans, shall take such action, including approving the issuance of shares of Crompton Common Stock, as may be necessary to give effect to the provisions of Sections 2.3(a), (b) and (c). (f) On, or as soon as practicable (but in any event not more than three Business Days) after, the Closing Date, Crompton shall prepare and file with the Securities and Exchange Commission (the "SEC") a registration statement on Form S-8 (or another appropriate form) registering a number of shares of Crompton Common Stock equal to the number of shares of Crompton Common Stock subject to the Adjusted Great Lakes Stock Options and the Adjusted Great Lakes Restricted Share Units. Such registration statement shall be kept effective (and the current status of the prospectus or prospectuses required thereby shall be maintained) at least for so long as any Adjusted Great Lakes Stock Options, Adjusted Great Lakes Restricted Share Units or any unsettled awards granted under the Great Lakes Stock Plans after the Effective Time may remain outstanding. (g) As soon as practicable after the Effective Time, Crompton shall deliver to the holders of Adjusted Great Lakes Stock Options, Adjusted Great Lakes Restricted Share Units and Adjusted Great Lakes Restricted Shares appropriate notices setting forth such holders' rights pursuant to the respective Great Lakes Stock Plans and the agreements evidencing the grants of such Adjusted Great Lakes Stock Options, Adjusted Great Lakes Restricted Share Units and Adjusted Great Lakes Restricted Shares and informing such holders that such Adjusted Great Lakes Stock Options, Adjusted Great Lakes Restricted Share Units and Adjusted Great Lakes Restricted Shares have been assumed by Crompton and shall continue in effect from and after the Effective Time in accordance with their terms (subject to the adjustments required by this Section 2.3 after giving effect to the Merger). (h) Except as otherwise contemplated by this Section 2.3 and except to the extent required under the respective terms of the respective Great Lakes Stock Options, Great Lakes Restricted Share Units and Great Lakes Restricted Shares (including any individual agreement providing for vesting of the applicable award upon a change in control of Great Lakes) all restrictions or limitations on transfer and vesting with respect to Great Lakes Stock Options, Great Lakes Restricted Share Units and Great Lakes Restricted Shares awarded under the Great Lakes Stock Plans or any other plan, program or arrangement of Great Lakes or any of its Subsidiaries, to the extent that such restrictions or limitations shall not have already lapsed, shall remain in full force and effect with respect to such options, restricted share units or restricted shares after giving effect to the Merger and the assumption by Crompton as set forth above. SECTION 2.4. Adjustments. Notwithstanding any provision of this Article II to the contrary (but without in any way limiting the covenants in Section 5.1(a) or 5.1(b)), if between the date of this Agreement and the Effective Time the outstanding shares of Great Lakes Common Stock or Crompton 10 Common Stock shall have been changed (or a provision for such change shall have been irrevocably made) into a different number of shares or a different class by reason of the occurrence or record date of any stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or similar transaction, the Exchange Ratio and other portions of this Agreement that would be affected by the number of such shares outstanding (including Section 2.3 and the limitations on dividends in Section 5.1) shall be appropriately adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or similar transaction.

Great Lakes and Crompton shall promptly provide the other copies of all filings made by such party with any Governmental Authority in connection with this Agreement and the transactions contemplated hereby. SECTION 5.2. No Solicitation by Great Lakes; Etc. (a) Great Lakes shall not, nor shall it authorize or permit any of its Subsidiaries, any of their respective directors, officers or employees or any investment banker, financial advisor, attorney, accountant or other advisor, agent or representative (collectively, "Representatives") retained by it or any of its Subsidiaries to, (i) solicit, initiate or encourage, or take any other action to facilitate, any inquiries or the making of any proposal that constitutes a Great Lakes Takeover Proposal or (ii) participate in any discussions or negotiations regarding, or furnish to any Person any information, or otherwise cooperate in any way with, any Great Lakes Takeover Proposal. Great Lakes shall, and shall cause its Subsidiaries and Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any Great Lakes Takeover Proposal. Notwithstanding the foregoing, prior to receipt of the Great Lakes Stockholder Approval, in response to a Great Lakes Takeover Proposal 47 that the Board of Directors of Great Lakes determines in good faith (after consultation with a financial advisor of nationally recognized reputation) constitutes or is reasonably likely to lead to a Great Lakes Superior Proposal, and which Great Lakes Takeover Proposal did not result from a breach of this Section 5.2(a), Great Lakes may (A) furnish information with respect to Great Lakes and its Subsidiaries to the Person making such Great Lakes Takeover Proposal (and its Representatives) pursuant to a customary confidentiality agreement that does not contain terms that would prevent Great Lakes from complying with its obligations under this Section 5.2, and (B) participate in discussions or negotiations with the Person making such Great Lakes Takeover Proposal (and its Representatives) regarding such Great Lakes Takeover Proposal. (b) For purposes of this Agreement, "Great Lakes Takeover Proposal" shall mean any written, bona fide proposal or offer (i) for a merger, consolidation, dissolution, recapitalization or other business combination involving Great Lakes, (ii) for the issuance of 25% or more of the equity securities of Great Lakes as consideration for the assets or securities of another Person or (iii) to acquire in any manner, directly or indirectly, 25% or more of the equity securities of Great Lakes or assets (including equity securities of any Subsidiary of Great Lakes) that represent 25% or more of the total consolidated assets of Great Lakes, in each case other than the transactions contemplated by this Agreement. (c) For purposes of this Agreement, "Great Lakes Superior Proposal" shall mean any written, bona fide offer made by a third party that if consummated would result in such Person (or its shareholders) owning, directly or indirectly, 50% or more of the shares of Great Lakes Common Stock then outstanding (or of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or 50% or more of the total consolidated assets of Great Lakes, which the Board of Directors of Great Lakes determines in good faith (after consultation with a financial advisor of nationally recognized reputation) to be more favorable to the stockholders of Great Lakes than the Merger (taking into account all the terms and conditions of such proposal and this Agreement). (d) In addition to the other obligations of Great Lakes set forth in this Section 5.2, Great Lakes shall promptly advise Crompton, orally and in writing, and in no event later than 24 hours after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, Great Lakes in respect of any Great Lakes Takeover Proposal, and shall, in any such notice to Crompton, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the material terms and conditions of any proposals or offers or the nature of any inquiries or contacts, and thereafter shall promptly keep Crompton informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests and of the status of any such discussions or negotiations. 48 (e) Neither the Board of Directors of Great Lakes nor any committee thereof shall (i) (A) withdraw (or modify in a manner adverse to Crompton), or propose to withdraw (or modify in a manner adverse to Crompton), the approval, recommendation or declaration of advisability by such Board of Directors or any such committee thereof of this Agreement or the Merger or (B) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Great Lakes Takeover Proposal (any action described in this clause (i) being referred to as a "Great Lakes Adverse Recommendation Change") or (ii) approve or recommend, or propose to approve or recommend, or allow Great Lakes or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting or related to any Great Lakes Takeover Proposal (other than a confidentiality agreement pursuant to Section 5.2(a)). Notwithstanding the foregoing, the Board of Directors of Great Lakes may (I) make a Great Lakes Adverse Recommendation Change if such Board of Directors determines in good faith (after consultation with outside counsel) that it is required to do so in order to comply with its fiduciary duties to the stockholders of Great Lakes under applicable Law or (II) in response to a Great Lakes Superior Proposal that did not result from a breach of Section 5.2(a), cause Great Lakes to terminate this Agreement pursuant to Section 8.1(f)(ii) (provided that Great Lakes shall pay to Crompton the Great Lakes Termination Fee as provided in Section 8.2(a) concurrently with such termination); provided, however, that (x) no Great Lakes Adverse Recommendation Change may be made in response to a Great Lakes Superior Proposal and (y) Great Lakes shall not terminate this Agreement pursuant to Section 8.1(f)(ii), in each case until after the third Business Day following Crompton's receipt of written notice from Great Lakes (a "Great Lakes Adverse Recommendation or Termination Notice") advising Crompton that the Board of Directors of Great Lakes intends to make such Great Lakes Adverse Recommendation Change or to cause Great Lakes to terminate this Agreement pursuant to Section 8.1(f)(ii) (it being understood and agreed that any amendment or change to the financial terms or other material terms of such Great Lakes Superior Proposal shall require a new Great Lakes Adverse Recommendation or Termination Notice and a new three Business Day period). In determining whether to make a Great Lakes Adverse Recommendation Change in response to a Great Lakes Superior Proposal or to cause Great Lakes to terminate this Agreement pursuant to Section 8.1(f)(ii), the Board of Directors of Great Lakes shall take into account any changes to the terms of this Agreement proposed by Crompton or other proposals or offers made by Crompton (in response to a Great Lakes Adverse Recommendation or Termination Notice or otherwise) in determining whether such Great Lakes Takeover Proposal still constitutes a Great Lakes Superior Proposal. (f) Nothing contained in this Section 5.2 shall prohibit Great Lakes or its Board of Directors from (i) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or (ii) making any required disclosure to the stockholders of Great Lakes if the Board of Directors of Great Lakes determines in good faith (after consultation with outside counsel) that failure to do so would constitute a violation of applicable Law; provided, however, that in no event shall Great Lakes or its Board of Directors or any committee thereof take, or agree or resolve to take, any action prohibited by Section 5.2(e). 49 SECTION 5.3. No Solicitation by Crompton; Etc. (a) Crompton shall not, nor shall it authorize or permit any of its Subsidiaries, any of their respective directors, officers or employees or any Representatives retained by it or any of its Subsidiaries to, (i) solicit, initiate or encourage, or take any other action to facilitate, any inquiries or the making of any proposal that constitutes a Crompton Takeover Proposal or (ii) participate in any discussions or negotiations regarding, or furnish to any Person any information, or otherwise cooperate in any way with, any Crompton Takeover Proposal. Crompton shall, and shall cause its Subsidiaries and Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any Crompton Takeover Proposal. Notwithstanding the foregoing, prior to receipt of the Crompton Stockholder Approval, in response to a Crompton Takeover Proposal that the Board of Directors of Crompton determines in good faith (after consultation with a financial advisor of nationally recognized reputation) constitutes or is reasonably likely to lead to a Crompton Superior Proposal, and which Crompton Takeover Proposal did not result from a breach of this Section 5.3(a), Crompton may (A) furnish information with respect to Crompton and its Subsidiaries to the Person making such Crompton Takeover Proposal (and its Representatives) pursuant to a customary confidentiality agreement that does not contain terms that would prevent Crompton from complying with its obligations under this Section 5.3, and (B) participate in discussions or negotiations with the Person making such Crompton Takeover Proposal (and its Representatives) regarding such Crompton Takeover Proposal. (b) For purposes of this Agreement, "Crompton Takeover Proposal" shall mean any written, bona fide proposal or offer (i) for a merger, consolidation, dissolution, recapitalization or other business combination involving Crompton, (ii) for the issuance of 25% or more of the equity securities of Crompton as consideration for the assets or securities of another Person or (iii) to acquire in any manner, directly or indirectly, 25% or more of the equity securities of Crompton or assets (including equity securities of any Subsidiary of Crompton) that represent 25% or more of the total consolidated assets of Crompton, in each case other than the transactions contemplated by this Agreement. (c) For purposes of this Agreement, "Crompton Superior Proposal" shall mean any written, bona fide offer made by a third party that if consummated would result in such Person (or its shareholders) owning, directly or indirectly, 50% or more of the shares of Crompton Common Stock then outstanding (or of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or 50% or more of the total consolidated assets of Crompton, which the Board of Directors of Crompton determines in good faith (after consultation with a financial advisor of nationally recognized reputation) to be more favorable to the stockholders of Crompton than the Merger (taking into account all the terms and conditions of such proposal and this Agreement). 50 (d) In addition to the other obligations of Crompton set forth in this Section 5.3, Crompton shall promptly advise Great Lakes, orally and in writing, and in no event later than 24 hours after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, Crompton in respect of any Crompton Takeover Proposal, and shall, in any such notice to Great Lakes, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the material terms and conditions of any proposals or offers or the nature of any inquiries or contacts, and thereafter shall promptly keep Great Lakes informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests and of the status of any such discussions or negotiations. (e) Neither the Board of Directors of Crompton nor any committee thereof shall (i) (A) withdraw (or modify in a manner adverse to Great Lakes), or propose to withdraw (or modify in a manner adverse to Great Lakes), the approval, recommendation or declaration of advisability by such Board of Directors or any such committee thereof of this Agreement or the Merger or the issuance of shares of Crompton Common Stock contemplated by this Agreement or (B) recommend, adopt or approve, or propose publicly to recommend, adopt or approve, any Crompton Takeover Proposal (any action described in this clause (i) being referred to as a "Crompton Adverse Recommendation Change") or (ii) approve or recommend, or propose to approve or recommend, or allow Crompton or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting or related to any Crompton Takeover Proposal (other than a confidentiality agreement pursuant to Section 5.3(a)). Notwithstanding the foregoing, the Board of Directors of Crompton may (I) make a Crompton Adverse Recommendation Change if such Board of Directors determines in good faith (after consultation with outside counsel) that it is required to do so in order to comply with its fiduciary duties to the stockholders of Crompton under applicable Law or (II) in response to a Crompton Superior Proposal that did not result from a breach of Section 5.3(a), cause Crompton to terminate this Agreement pursuant to Section 8.1(e)(ii) (provided that Crompton shall pay to Great Lakes the Crompton Termination Fee as provided in Section 8.2(c) concurrently with such termination); provided, however, that (x) no Crompton Adverse Recommendation Change may be made in response to a Crompton Superior Proposal and (y) Crompton shall not terminate this Agreement pursuant to Section 8.1(e)(ii), in each case until after the third Business Day following Great Lakes' receipt of written notice from Crompton (a "Crompton Adverse Recommendation or Termination Notice") advising Great Lakes that the Board of Directors of Crompton intends to make such Crompton Adverse Recommendation Change or to cause Crompton to terminate this Agreement pursuant to Section 8.1(e)(ii) (it being understood and agreed that any amendment or change to the financial terms or other material terms of such Crompton Superior Proposal shall require a new Crompton Adverse Recommendation or Termination Notice and a new three Business Day period). In determining whether to make a Crompton Adverse Recommendation Change in response to a Crompton Superior Proposal or to cause Crompton to terminate this Agreement pursuant to Section 8.1(e)(ii), the Board of Directors of Crompton shall take into account any changes to the terms of this Agreement proposed by Great Lakes or other proposals or offers made by Great Lakes (in response to a Crompton Adverse Recommendation or Termination Notice or otherwise) in determining whether such Crompton Takeover Proposal still constitutes a Crompton Superior Proposal. 51 (f) Nothing contained in this Section 5.3 shall prohibit Crompton or its Board of Directors from (i) taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or (ii) making any required disclosure to the stockholders of Crompton if the Board of Directors of Crompton determines in good faith (after consultation with outside counsel) that failure to do so would constitute a violation of applicable Law; provided, however, that in no event shall Crompton or its Board of Directors or any committee thereof take, or agree or resolve to take, any action prohibited by Section 5.3(e).

(b) For six years after the Effective Time, Crompton shall maintain in effect Great Lakes' current directors' and officers' liability insurance in respect of acts or omissions occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby), covering each person currently covered by Great Lakes' directors' and officers' liability insurance policy (a true and complete copy of which has been heretofore made available to Crompton), on terms with respect to such coverage and amount no less favorable than those of such policy in effect on the date hereof; provided, however, that Crompton may substitute therefor policies of Crompton containing terms with respect to coverage and amount no less favorable to such Indemnified Parties; provided, further, that in satisfying its 57 obligation under this Section 6.4(b), Crompton shall not be obligated to pay aggregate premiums in excess of 300% of the amount paid by Great Lakes in its last full fiscal year, it being understood and agreed that Crompton shall nevertheless be obligated to provide such coverage as may be obtained for such 300% amount. Crompton shall have the right to cause coverage to be extended under Great Lakes' directors' and officers' liability insurance policy by obtaining a six-year "tail" policy on terms and conditions no less favorable than Great Lakes' existing directors' and officers' liability insurance policy, and such "tail" policy shall satisfy the provisions of this Section 6.4(b). (c) If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and other assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Surviving Corporation shall expressly assume the obligations set forth in this Section 6.4. (d) Crompton, from and after the Effective Time, hereby unconditionally guarantees the timely payment of all funds owed by, and the timely performance of all other obligations of, the Surviving Corporation under this Section 6.4. Crompton agrees that its payment obligations hereunder are unconditional, irrespective of the validity or enforceability of this Agreement against the Surviving Corporation or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (other than the defenses of statute of limitations, which are not waived). Crompton hereby acknowledges that its obligations under this Section 6.4 constitute a guaranty of payment and not merely of collectability and Crompton hereby waives (i) promptness, diligence, presentment, demand of payment, protest and order in connection with this guarantee and (ii) any requirement that any party enforcing the guarantee exhaust any right to take any action against the Surviving Corporation or any other person prior to or contemporaneously with proceeding to exercise any right against Crompton hereunder. (e) The provisions of this Section 6.4: (i) are intended to be for the benefit of, and will be enforceable by, each Indemnified Party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights, including in the case of any Indemnified Party, any right to indemnification or contribution, that any such person may have by contract or otherwise. SECTION 6.5. Fees and Expenses. Except as provided in Section 8.2, all fees and expenses incurred in connection with this Agreement, the Merger and the other transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated, except that Crompton and Great Lakes each shall bear and pay 50% of the costs and expenses incurred in connection with filing, printing and mailing the Form S-4 and the Joint Proxy Statement and the filing fee under the HSR Act. 58 SECTION 6.6. Public Announcements. Great Lakes and Crompton shall consult with each other before issuing, and give each other the opportunity to review and comment upon, any press release or other public statements with respect to the transactions contemplated by this Agreement, including the Merger, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange or national securities quotation system. The parties agree that the initial press release to be issued with respect to the transactions contemplated by this Agreement shall be in the form heretofore agreed to by the parties. SECTION 6.7. Affiliates. As soon as practicable after the date hereof, Great Lakes shall deliver to Crompton a letter identifying all Persons who Great Lakes believes will be at the time this Agreement is submitted for adoption by the stockholders of Great Lakes, "affiliates" of Great Lakes for purposes of Rule 145 under the Securities Act and applicable SEC rules and regulations. Great Lakes shall use its reasonable best efforts to cause each such Person to deliver to Crompton on or prior to the Closing Date a written agreement substantially in the form attached as Exhibit B. SECTION 6.8. Stock Exchange Listing. To the extent Crompton does not issue treasury shares in the Merger which are already listed, Crompton shall use its reasonable best efforts to cause the shares of Crompton Common Stock to be issued in the Merger and the exercise of Great Lakes Stock Options and Great Lakes Restricted Share Units as adjusted pursuant to Section 2.3 to be approved for listing on the New York Stock Exchange, subject to official notice of issuance, prior to the Closing Date. SECTION 6.9. Stockholder Litigation. Great Lakes and Crompton shall give the other the opportunity to participate in the defense or settlement of any stockholder litigation against either party and/or its directors relating to the transactions contemplated by this Agreement. SECTION 6.10. Tax Treatment. (a) Great Lakes and Crompton shall execute and deliver to Weil, Gotshal & Manges LLP, counsel to Great Lakes, and Mayer, Brown, Rowe & Maw LLP, counsel to Crompton, certificates substantially in the forms attached hereto as Exhibits C and D at such time or times as reasonably requested by such law firms in connection with their delivery of the opinions referred to in Sections 7.2(c) and 7.3(c). None of Great Lakes, Crompton or Merger Sub shall take or cause to be taken any action which would cause to be untrue any of the representations in such certificates. (b) Great Lakes, Crompton and Merger Sub intend that the transactions contemplated hereby will qualify as a "reorganization" within the meaning of Section 368(a) of the Code and the parties hereto will take the position for all Tax purposes that the transactions contemplated hereby so qualify unless a contrary position is required by a final determination within the meaning of Section 1313 of the Code. Great Lakes, Crompton and Merger Sub shall each use their respective reasonable best efforts to cause the transactions contemplated hereby to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and shall not take actions, cause actions to be taken or fail to take actions that are reasonably likely to prevent such result. 59 SECTION 6.11. Employee Matters. (a) For a period ending not earlier than the first anniversary of the Effective Time, employees of Great Lakes or any of its Subsidiaries who continue their employment after the Effective Time (the "Affected Employees") shall be provided, while they continue to be employed by Great Lakes, Crompton or any of their respective Subsidiaries, base salary or hourly wage rates that are no less favorable than those then provided for similarly situated employees of Crompton. Nothing in this Section 6.11 shall be deemed to require Great Lakes, Crompton or any of their respective Subsidiaries to continue the employment of any Affected Employee after the Effective Time. (b) For a period ending not earlier than the first anniversary of the Effective Time, the Affected Employees shall be provided employee benefits that are not materially less favorable in the aggregate than the benefits then provided to similarly situated employees of Crompton; provided, however, that continuing the material Great Lakes Plans during this one year period shall be deemed to satisfy the requirements of this Section 6.11(b). (c) With respect to any benefit plan, program, arrangement (including any "employee benefit plan" (as defined in Section 3(3) of ERISA) and any vacation or sick leave program), Crompton shall, and shall cause the Surviving Corporation to, recognize the service with Great Lakes or any of its Subsidiaries immediately prior to the Effective Time of the Affected Employees for purposes of eligibility, vesting and, solely for purposes of vacation and sick leave (but not for any other plan, program or arrangement), benefit accrual, under such plan or program. (d) With respect to any welfare plan in which employees of Great Lakes or any of its Subsidiaries may become eligible to participate after the Effective Time, other than the Great Lakes Plans in which such employees participate immediately prior to the Effective Time, Crompton shall, and shall cause the Surviving Corporation to, (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees to the extent such conditions were satisfied under the corresponding Great Lakes Plans immediately prior to the Effective Time, and (ii) provide each such employee with credit for any co-payments and deductibles paid prior to the Effective Time (but in the same calendar year in which the Effective Time occurs) under a corresponding Great Lakes Plan towards satisfying any analogous deductible or out-of-pocket requirements to the extent applicable under any such plan. (e) With respect to any accrued but unused vacation time to which any Affected Employee is entitled pursuant to the vacation policy applicable to such employee immediately prior to the Effective Time, Crompton shall, and shall cause the Surviving Corporation to, (i) either allow such Affected Employee to use such accrued vacation or pay to such Affected Employee in cash the amount of 60 such accrued vacation pay and (ii) to the extent required by the terms of the Great Lakes vacation policy as in effect immediately prior to the Effective Time, pay in cash the accrued vacation of any Affected Employee whose employment terminates for any reason prior to the close of business on the last calendar day of the year in which the Effective Time occurs. (f) With respect to jurisdictions outside of the United States, Great Lakes shall, and shall cause its Affiliates to, comply with applicable requirements of local Laws relating to employees and employee benefit plans with respect to the effect of the transactions contemplated by this Agreement. SECTION 6.12. Rule 16b-3. Prior to the Effective Time, Great Lakes and Crompton shall take such steps as may be reasonably requested by any party hereto to cause dispositions of Great Lakes equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of Great Lakes to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with that certain No-Action Letter dated January 12, 1999 issued by the SEC regarding such matters. SECTION 6.13. Governance. (a) Crompton shall cause the number of directors that will comprise the full Board of Directors of Crompton at the Effective Time to be eleven. Crompton shall cause the election of each of the five Great Lakes Board Designees to become directors of Crompton as of, and conditioned upon the occurrence of, the Effective Time. Crompton shall cause the remaining six members of the Board of Directors of Crompton as of the Effective Time to consist of five of the individuals who are members of the Board of Directors of Crompton as of the date of this Agreement (which individuals will be designated by Crompton in writing prior to the mailing of the Joint Proxy Statement) and the individual who is the Chairman and Chief Executive Officer of Crompton (collectively, the "Original Crompton Board Members"). Crompton shall use its best efforts to cause each Great Lakes Board Designee whose term expires in 2006 or 2007 to be re-nominated for one additional term, unless such Great Lakes Board Designee does not meet Crompton's board membership criteria then in effect or such Great Lakes Board Designee is the Great Lakes Board Designee designated to resign from or not seek re-election to the Board of Directors of Crompton under Section 6.13(b). For purposes of this Agreement, "Great Lakes Board Designees" shall mean the five individuals, each of whom must be serving as a member of the Board of Directors of Great Lakes as of the date of this Agreement, designated by Great Lakes in writing prior to the mailing of the Joint Proxy Statement to be elected to the Board of Directors of Crompton as of, and conditioned upon the occurrence of, the Effective Time. The Great Lakes Board Designees shall be allocated among the various classes of the Board of Directors of Crompton in a manner to be reasonably agreed upon by Great Lakes and Crompton prior to the mailing of the Joint Proxy Statement, provided that the total number of directors in each of Class I, Class II and Class III shall be as nearly equal in number as possible. 61 (b) As of the 2006 annual meeting of stockholders of Crompton, Crompton shall cause the number of directors that will comprise the full Board of Directors of Crompton to be nine. In order to achieve such reduced number of directors, Crompton shall cause one Great Lakes Board Designee and one of the Original Crompton Board Members to either resign from or to not seek re-election to the Board of Directors of Crompton as of or at the 2006 annual meeting of stockholders of Crompton. (c) Notwithstanding anything to the contrary in this Section 6.13, after the Effective Time, Crompton shall have the right, and shall be permitted, to take any action inconsistent with Sections 6.13(a) and 6.13(b) if, after the Effective Time, the entire Board of Directors of Crompton unanimously approves the taking of such action. SECTION 6.14. Crompton 2004 Indentures. Crompton shall use its reasonable best efforts to cause the condition to Closing set forth in Section 7.1(f) to be satisfied as soon as reasonably practicable following the date of this Agreement (it being understood that the use of such reasonable best efforts shall include the preparation and commencement of the Crompton Consent Solicitations), and Great Lakes shall use its reasonable best efforts to cooperate with Crompton in connection therewith. Without limiting the generality of the foregoing, Crompton shall provide Great Lakes (a) drafts of all consent solicitation materials that Crompton proposes to send to holders of Crompton's Senior Floating Rate Notes due 2010 (the "Crompton Floating Rate Notes") or Crompton's 9-7/8% Senior Notes due 2012 (the "Crompton 9-7/8% Notes" and, together with the Crompton Floating Rate Notes, the "Crompton Notes") seeking such holders' consent to one or more amendments or to the waiver of one or more covenants (the "Merger Amendments") to (i) the Indenture, dated as of August 16, 2004, among Crompton, the guarantors party thereto and Wells Fargo Bank, National Association, as trustee, relating to the Crompton Floating Rate Notes (the "Crompton Floating Rate Notes Indenture"), and (ii) the Indenture, dated as of August 16, 2004, among Crompton, the guarantors party thereto and Wells Fargo Bank, National Association, as trustee, relating to the Crompton 9-7/8% Notes (the "Crompton 9-7/8% Notes Indenture" and, together with the Crompton Floating Rate Notes Indenture, the "Crompton 2004 Indentures") which provide that the consummation of the Merger and the other transactions contemplated by this Agreement shall not constitute a Default or an Event of Default under either of the Crompton 2004 Indentures and (b) a reasonable opportunity to consult with Crompton as to the form and content of, and a reasonable opportunity to review and comment on, such consent solicitation materials prior to the time that Crompton commences such consent solicitations (the "Crompton Consent Solicitations"). In addition, Crompton shall be entitled to seek in connection with the Crompton Consent Solicitations the consent of the holders of the Crompton Notes to one or more other amendments (collectively, the "Discretionary Amendments") to the Crompton 2004 Indentures so long as Crompton determines in good faith, after consultation with its financial and legal advisors, that seeking such Discretionary Amendments would not reasonably be expected to prevent or materially delay obtaining such holders' consent to the Merger Amendments; provided, however, that if Crompton elects to seek consent to a Discretionary Amendment and it thereafter becomes reasonably apparent that such consent cannot be obtained without preventing or materially delaying the Merger, Crompton shall promptly eliminate from the Crompton Consent Solicitations the request for consent to such Discretionary Amendment and continue to seek the Merger Amendments in accordance with the terms of this Section 6.14. 62 SECTION 6.15. Dividend Coordination. Great Lakes shall coordinate with Crompton the declaration, setting of record dates and payment dates of dividends on Great Lakes Common Stock so that holders of shares of Great Lakes Common Stock do not receive a dividend on both Great Lakes Common Stock and Crompton Common Stock received in the Merger in respect of any calendar quarter or fail to receive a dividend on either Great Lakes Common Stock or Crompton Common Stock received in the Merger in respect of any calendar quarter. SECTION 6.16. Filing of Annual Report on Form 10-K. Crompton shall file its annual report on Form 10-K for the year ended December 31, 2004 on or prior to March 16, 2005. SECTION 6.17. Credit Agreement. Crompton shall use its reasonable best efforts to have in full force and effect as of the Closing Date a new credit agreement or similar agreement that replaces the Crompton Credit Agreement (the "New Credit Agreement") under which the execution of this Agreement and the consummation of the transactions contemplated hereby will not violate or otherwise cause a default under the New Credit Agreement; provided, however, that Crompton shall not be required to comply with this Section 6.17 if it obtains the consent of the requisite percentage of lenders under the Crompton Credit Agreement to the consummation of the transactions contemplated by this Agreement. Crompton shall consult with Great Lakes regarding, and shall provide Great Lakes with a reasonable opportunity to review and comment on, such proposed New Credit Agreement prior to the execution thereof by Crompton.

(d) No Injunctions or Restraints. No temporary restraining order, preliminary or permanent injunction or other judgment or order issued by any court of competent jurisdiction or other statute, law, rule, legal restraint or prohibition (collectively, "Restraints") shall be in effect preventing the consummation of the Merger.

The consideration to be received in the Merger by the stockholders of Great Lakes was the result of arm's-length bargaining between the managements of Great Lakes and Crompton. The fair market value of the common stock of Crompton ("Crompton Common Stock") and any cash received in lieu of fractional shares to be received by each stockholder of Great Lakes will be approximately equal to the fair market value of the common stock of Great Lakes ("Great Lakes Common Stock") surrendered in the Merger. 2. Prior to and in connection with the Merger, no outstanding stock of Great Lakes has been or will be (i) redeemed by Great Lakes, or (ii) acquired by a person related to Great Lakes (with the meaning of Treasury Regulation Section 1.368-1(e)(3) determined without regard to Treasury Regulation Section 1.368-1(e)(3)(i)(A)) for consideration other than Crompton Common Stock or Great Lakes Common Stock. 3. To the best knowledge of Great Lakes, there is no plan or intention on the part of any stockholders of Great Lakes to sell, exchange, or otherwise dispose of Crompton Common Stock to be received in the Merger by such holder of Great Lakes Common Stock directly or indirectly to Crompton or to a person related to Crompton (within the meaning of Treasury Regulation Section 1.368-1(e)(3)) for consideration other than Crompton Common Stock. 4. Great Lakes has no outstanding equity interests other than as described in Section 3.2 of the Merger Agreement. At the Effective Time and following the Merger, Great Lakes will not have outstanding any warrants, options, convertible securities, or any other type of right pursuant to which any person could acquire stock in Great Lakes that, if exercised or converted, would affect Crompton's acquisition or retention of "control" of Great Lakes within the meaning of Section 368(c) of the Internal Revenue Code of 1986, as amended (the "Code"). 5. Great Lakes has no plan or intention to alter the terms of the Great Lakes Common Stock or to issue additional shares of its stock that would result in Crompton losing "control" of Great Lakes within the meaning of Section 368(c) of the Code. 6. Holders of Great Lakes Common Stock do not have dissenter's rights in connection with the Merger. 7. Great Lakes and its stockholders will pay their respective expenses, if any, incurred in connection with the Merger, except that the costs and expenses described in Section 6.5 of the Merger Agreement shall be borne by the parties in accordance therewith. 8. Great Lakes is not an investment company as defined in Section 368(a)(2)(F)(iii) and (iv) of the Code. 9. Great Lakes is not under the jurisdiction of a court in a Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the Code. 10. There is no intercorporate indebtedness existing between Crompton and Great Lakes or between Merger Sub and Great Lakes that was issued, acquired, or will be settled at a discount. 11. In the Merger, shares of Great Lakes Common Stock representing control of Great Lakes within the meaning of Section 368(c) of the Code will be exchanged solely for Crompton Common Stock. In connection with the Merger, no shares of Great Lakes Common Stock will be exchanged for cash or other property originating with Crompton or any person related to Crompton (within the meaning of Treasury Regulation Section 1.368-1(e)(3)) except for cash received by holders of Great Lakes Common Stock in lieu of fractional shares of Crompton Common Stock. Further, no liabilities of Great Lakes or of the stockholders of Great Lakes will be assumed by Crompton, nor to the best of the knowledge of the management of Great Lakes, will any Great Lakes Common Stock be subject to any liabilities. 12. In connection with the Merger, Great Lakes has not sold, transferred, or otherwise disposed of any of its assets as would prevent Crompton or members of its qualified group (within the meaning of Treasury Regulation 1.368-1(d)(4)(ii)) from causing Great Lakes after the Merger to continue the historic business of Great Lakes or to use a significant portion of Great Lakes' historic business assets in a business. 83 13. On the date of the Merger, the fair market value of the assets of Great Lakes will exceed the sum of its liabilities, plus the amount of liabilities, if any, to which the assets are subject. 14. Following the Merger, Great Lakes will hold at least 90% of the fair market value of its net assets and at least 70% of the fair market value of its gross assets held immediately prior to the Merger. For purposes of this representation, amounts paid by Great Lakes to Great Lakes stockholders who receive cash or other property in the Merger, amounts used by Great Lakes to pay its reorganization expenses and those of its stockholders, and all redemptions and distributions (except for regular, normal dividends) made by Great Lakes will be included as assets of Great Lakes immediately prior to the Merger. 15. None of the compensation to be received by any stockholder-employee of Great Lakes in the Merger will be separate consideration for, or allocable to, any of their shares of Great Lakes Common Stock; none of the Crompton Common Stock to be received by any stockholder-employee of Great Lakes will be separate consideration for, or allocable to, any employment or consulting agreement; and the compensation to be paid to any stockholder-employee after the Merger pursuant to arrangements entered into in connection with the Merger will be for services actually rendered and will be commensurate with amounts paid to third parties bargaining at arm's-length for similar services. 16. All options, warrants, or rights to acquire shares of Great Lakes Common Stock were issued with an exercise price no less than fair market value at the time of issue. 17. The Merger is being effected for bona fide business reasons, as described in the Joint Proxy Statement. 18. The Merger Agreement (including all exhibits and attachments thereto) represents the full and complete agreement between Crompton and Great Lakes regarding the Merger, and there are no other written or oral agreements regarding the Merger. 19. The payment of cash in lieu of fractional shares of Crompton Common Stock in the Merger is solely for the purpose of avoiding the expense and inconvenience to Crompton of issuing fractional shares, if any, and does not represent separately bargained-for consideration. The total cash consideration that will be paid in the Merger to holders of Great Lakes Common Stock in lieu of issuing fractional shares of Crompton Common Stock will not exceed one percent (1%) of the total consideration that will be issued in the Merger to holders of Great Lakes Common Stock in exchange for their Great Lakes Common Stock. The undersigned recognizes that opinions issued by counsel of Crompton and Great Lakes regarding certain federal income tax consequences of the Merger ("Tax Opinions") will be based on the representations set forth herein and on the statements contained in the Merger Agreement and documents related thereto. The Tax Opinions will be subject to certain limitations and qualifications including that they may not be relied upon if any such representations are not accurate in all respects.
