WHEREAS, each of OCC and Geon is a "Parent" for purposes of this Agreement; and WHEREAS, each of OPC and Geon is a "Subject Parent" for purposes of this Agreement; PROVIDED, HOWEVER, that neither OPC nor Geon shall be a "Subject Parent" from and after the expiration of 12 months from the date on which it and its Affiliates no longer hold any Units in the Partnership; and WHEREAS, Occidental PVC Compound LP, Inc., a Delaware corporation ("OCC Partner Sub"), is a direct or indirect wholly-owned subsidiary of OCC; and OCC is an indirect wholly-owned subsidiary of OPC; and WHEREAS, 1999 General Compounding Partner Inc., a Delaware corporation ("Geon GP"), and 1999 Limited Compounding Partner Inc., a Delaware corporation ("Geon LP" and, together with Geon GP, the "Geon Partner Subs"), are both direct wholly-owned subsidiaries of Geon; and WHEREAS, OCC and Geon entered into a Master Transaction Agreement, dated December 22, 1998 (the "Master Transaction Agreement"), providing for, among other things, the formation of the Partnership pursuant to the Limited Partnership Agreement of the Partnership dated as of the date of this Agreement (the "Partnership Agreement") and the admission of the Geon Partner Subs and the OCC Partner Sub as partners in the Partnership. The Geon Partner Subs and the OCC Partner Sub, collectively or individually, as the context may require, are referred to herein as the "Partner Subs"; and WHEREAS, this Agreement is essential to the consummation of the closing pursuant to the Master Transaction Agreement; and WHEREAS, each Parent is willing to subject the Partner Sub Stock (as defined in Section 1.1) to certain restrictions on transfer, as set forth in this Agreement; and 2 4 WHEREAS, each of OPC and Geon is willing to agree to certain covenants in favor of the other in connection with the closing of the transactions contemplated by the Master Transaction Agreement; NOW THEREFORE, in consideration of the foregoing and the mutual promises and covenants of the Parties, the Parties hereby agree as follows: SECTION 1 OWNERSHIP AND BUSINESS OF PARTNER SUBS -------------------------------------- 1.1 RESTRICTIONS ON TRANSFER AND PLEDGE OF PARTNER SUB STOCK. (a) Each Parent agrees that, except as otherwise provided below in this Section 1, or with the written consent of the other Parent, which consent may be granted or withheld in such Parent's sole discretion, it will not, in any transaction or series of transactions, directly or indirectly, (i) sell, assign or otherwise dispose of, whether by act, deed, merger or otherwise ("Transfer") or (ii) mortgage, pledge, encumber or create or suffer to exist any lien or encumbrance upon or security interest in ("Pledge"), all or any part of the capital stock or other equity interests (including any securities convertible into or exchangeable for or carrying any rights to purchase, subscribe for or otherwise acquire any such capital stock or other equity interests) of its Partner Subs (collectively, the "Partner Sub Stock"). (Each of the defined terms "Transfer"and "Pledge" is used herein both as a noun and as a verb.) Any attempt by a Parent to Transfer or Pledge all or a portion of its Partner Sub Stock in violation of this Agreement shall be void AB INITIO and shall not be effective to Transfer such Partner Sub Stock or any portion thereof. The Partnership Agreement contains provisions relating to the Transfer and Pledge of the Partner Subs' direct interests in the Partnership. (b) Each Parent agrees that all certificates (if any) representing Partner Sub Stock, whether currently owned or hereafter acquired, shall carry the following legend, which legend each Parent agrees to cause to be placed thereon and to cause to remain thereon as long as the Partner Sub Stock is subject to the restrictions of this Agreement: THE SALE, ASSIGNMENT, PLEDGE OR OTHER TRANSFER OR HYPOTHECATION OF THE STOCK OR OTHER EQUITY INTEREST REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO CERTAIN RESTRICTIONS PURSUANT TO AND MAY NOT BE EFFECTED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF AN AGREEMENT BINDING UPON THE OWNER OF THE STOCK OR OTHER EQUITY INTEREST REPRESENTED HEREBY. THE OWNER OR ISSUER WILL FURNISH A COPY OF SUCH AGREEMENT TO ANY PROPOSED TRANSFEREE OR PLEDGEE WITHOUT CHARGE UPON REQUEST. (c) Without the need for the consent of any Person and without the application of the requirements of Section 1.2, each Parent may Transfer all (but not less than all) of its Partner Sub Stock, if such Transfer is: (i) in connection with (A) a merger, consolidation, conversion, share 3 5 exchange or Change of Control of such Parent or (B) a sale or other disposition by such Parent of assets including the Partner Sub Stock where such Partner Sub Stock constitutes less than 50% of the book value of the aggregate assets to be sold or disposed of, as reflected on such Parent's most recent audited consolidated (or combined) financial statements; (ii) to an 80%-Owned Affiliate of such Parent; or (iii) to the shareholders of (A) such Parent, in the case of Geon, or (B) OPC, in the case of OCC; PROVIDED, HOWEVER, that the requirements of Section 1.2(d)(i)-(vi) must be satisfied in connection therewith. For purposes of the preceding sentence, the term "Change of Control" shall (A) for Geon be defined in the same way as that term is defined for Geon in Section 2.2 in its capacity as a Subject Parent and (B) for OCC mean an event or circumstance that results in OCC's no longer being an Affiliate of OPC. (d) Except as provided in Section 1.1(c), nothing in this Agreement shall prevent or restrict the Transfer or Pledge of the capital stock, equity ownership interests or other securities of a Parent or any Person that owns a direct or indirect interest in a Parent, and no such Transfer or Pledge of securities issued by a Parent shall be deemed to constitute a Transfer or Pledge of Partner Sub Stock hereunder. (e) Each Parent (so long as such Parent is performing its obligations hereunder) may Pledge all (but not less than all) of its Partner Sub Stock in connection with a loan to such Parent, PROVIDED that (i) the loan to such Parent has been approved by the Partnership and (ii) the Pledge shall be evidenced by an instrument, reasonably satisfactory to the Partnership, wherein, in the case of the Partner Sub Stock of Geon GP and Geon LP, the lender receiving such Pledge shall agree that in the event such lender obtains a right of foreclosure on Geon's Partner Sub Stock, such lender will foreclose on the Partner Sub Stock of Geon's Partner Subs proportionately so that such lender will in all events hold portions of Partner Sub Stock of Geon GP and Geon LP proportionate to Geon's holdings thereof. 1.2 RIGHT OF FIRST REFUSAL AND RIGHT OF FIRST OPTION. (a) Without the consent of the other Parent, no Parent may Transfer less than all of its Partner Sub Stock, and unless such Transfer is otherwise permitted by Section 1.1, no Parent may Transfer its Partner Sub Stock, directly or indirectly, for consideration other than cash. Unless such Transfer is otherwise permitted by Section 1.1, any Parent (the "Selling Parent") that receives a bona fide offer to purchase all of its Partner Sub Stock that it desires to accept (an "Offer") or that otherwise desires to Transfer all of its Partner Sub Stock to any Person shall give written notice (the "Initial Notice") to the Partnership and the other Parent (the "Offeree Parent") stating that the Selling Parent has received an Offer or otherwise desires to Transfer its Partner Sub Stock and shall set forth the cash purchase price and all other terms of the Offer or the cash purchase price (established as provided below) and all other terms on which it otherwise is willing to sell its Partner Sub Stock (in each case, the "Offer Terms"). In establishing the Offer Terms for a proposed sale that does not involve an Offer, the Selling Parent shall obtain an appraisal from an independent appraiser with a reasonable level of industry experience of the cash price that a willing buyer under no compulsion to buy would pay and a willing seller under no compulsion to sell would accept for the Partner Sub 4 6 Stock of the Selling Parent (the "Fair Market Value"). Delivery of an Initial Notice shall constitute the irrevocable offer of the Selling Parent to sell its Partner Sub Stock to the Offeree Parent hereunder. (b) The Offeree Parent shall have the option, exercisable by delivering written notice (the "Acceptance Notice") of such exercise to the Selling Parent within 60 days of the date of the Initial Notice, to elect to purchase all, but not less than all, of the Partner Sub Stock of the Selling Parent on the Offer Terms described in the Initial Notice. The Acceptance Notice shall set a date for closing the purchase, such date to be not less than 30 nor more than 90 days after delivery of the Acceptance Notice; PROVIDED, HOWEVER, that such time period shall be subject to extension as reasonably necessary (up to a maximum of an additional 120 days after such 90 day period) in order to comply with any applicable filing and waiting period requirements under the Hart-Scott-Rodino Antitrust Improvements Act (or any successor statute) or other Legal Requirement. The closing shall be held at the Partnership's offices. The purchase price for the Selling Parent's Partner Sub Stock shall be paid in immediately available funds delivered at the closing, and all actions at the closing shall conform in all material respects to the Offer Terms. (c) If the Offeree Parent does not elect to purchase all of the Selling Parent's Partner Sub Stock within 60 days after the receipt of the Initial Notice, the Selling Parent shall have a further 180 days during which it may, subject to Section 1.2(d), consummate the sale of its Partner Sub Stock (i) substantially in accordance with the terms of the Offer or (ii) if no Offer is involved, to a third party purchaser on terms that are not substantially more favorable to such purchaser than the Offer Terms and at a price equal to not less than 90% of the Fair Market Value of the Partner Sub Stock. If the sale is not completed within such further 180-day period, the Initial Notice shall be deemed to have expired and a new notice and offer shall be required before the Selling Parent may make any Transfer of its Partner Sub Stock. If the Selling Parent receives a written offer during such further 180-day period from a third party purchaser that is for less than 90% of the Fair Market Value, and the Selling Parent is willing to accept the offer, then (1) the offer shall be treated as an Offer, and (2) the Selling Parent must comply with the provisions of this Section 1.2 before the Selling Parent may make any Transfer of its Partner Sub Stock to the third party purchaser that made the Offer. (d) Notwithstanding the foregoing provisions of this Section 1.2, except as provided in Section 1.1(c), a Parent may Transfer its Partner Sub Stock only if all of the following occur: (i) The proposed transferor is not in default in the timely performance of any of its material obligations to the Partnership. (ii) The Transfer is accomplished in a non-public offering in compliance with, and exempt from, the registration and qualification requirements of all federal and state securities laws and regulations. 5 7 (iii) The Transfer does not cause a default under any material contract (A) that has been approved unanimously by the Partnership Governance Committee and (B) to which the Partnership is a party or by which the Partnership or any of its properties is bound. (iv) The Successor Parent executes an appropriate agreement to be bound by this Agreement. (v) The transferor and transferee bear all reasonable costs incurred by the Partnership in connection with the Transfer. (vi) The provisions of Section 1.2(e) are satisfied. (vii) The Successor Parent must have sufficient resources to assume the obligations of the Parent, including any capital that may reasonably be expected to be requested from its Partner Subs by the Partnership under the then effective Strategic Plan, or the Successor Parent's obligations must be supported by a guarantee, letter of credit or other credit support reasonably satisfactory to the other Parent, and such Successor Parent must otherwise be reasonably acceptable to the other Parent. (e) Geon may Transfer the Partner Sub Stock of either of its Partner Subs to any Person only if it simultaneously Transfers the Partner Sub Stock of its other Partner Sub to such Person or a wholly-owned Affiliate of such Person. 1.3 EFFECT OF TRANSFER. Upon completion of any Transfer that is permitted hereunder, the Successor Parent shall succeed to and be substituted for the applicable Parent, with the same effect as if it had been named herein, and unless such Parent shall then be an Affiliate of such Successor Parent, such Parent and its Affiliates shall thereupon be released from all obligations under this Section 1 and Section 3. For purposes of this Section 1, the term "Successor Parent" shall mean the acquiring, succeeding or surviving entity in any permitted Transfer that directly or indirectly owns the applicable Partner Sub Stock following such transaction, if other than a Parent. In addition, a Parent and its Affiliates shall be released from all obligations under this Section 1 and (except as provided in Section 3.10) Section 3 at such time as neither such Parent nor any of its Affiliates holds any Units in the Partnership pursuant to a Transfer of such Units in accordance with the Partnership Agreement. 1.4 SPECIAL PURPOSE SUBSIDIARIES. Each Parent covenants and agrees that (i) the business of its Partner Subs shall be restricted solely to the holding of the respective interests in the Partnership and the doing of things necessary or appropriate in connection therewith, and (ii) it will cause its Partner Subs not to own any assets, incur any liabilities or engage, participate or invest in any business outside the scope of their businesses as described in clause (i) hereof. 6 8 SECTION 2 STANDSTILL AGREEMENT AND CERTAIN OTHER MATTERS ---------------------------------------------- 2.1 STANDSTILL.
