("Borrower"), Bank of America National Trust and Savings Association, successor by merger to Bank of America Illinois, as Agent (the "Agent") and a Lender and the other Lenders party thereto (the "Loan Agreement"). Unless otherwise defined herein, capitalized terms used herein shall have the meanings provided to such terms in the Loan Agreement. 1. Background. Borrower has informed Agent and Lenders that (a) Borrower's Subsidiary, PAI, has established three new Subsidiaries, PCI Chemicals Canada Inc., a New Brunswick corporation ("PCI Canada"), PCI Carolina, Inc., a Delaware corporation ("PCI Carolina") and Pioneer Licensing, Inc., a Delaware corporation ("Licensing"); (b) PCI Canada and PCI Carolina have agreed to acquire (the PCI Acquisition") certain of the assets, and assume certain of the liabilities, of ICI Canada Inc. ("ICI Canada") and ICI Americas Inc. ("ICI Americas"); (c) PAI has agreed to obtain a $83,000,000 term loan (the "Term Loan") from DLJ Capital Funding, Inc., ("DLJ") and Salomon Brothers Holding Company Inc. ("Salomon"); (d) PCI Canada has agreed to issue $175,000,000 of senior secured notes (the "Senior Secured Notes"), the sale of which will be underwritten by DLJ and Salomon; (e) PCI Canada and PCI Carolina has each agreed to grant to the Collateral Agent for the lenders in respect of the Term Loan and the Senior Secured Notes, a lien on its real estate, equipment and certain general intangibles, and certain related property (the "Collateral Grant"), to secure the obligations in respect of the Term Loan and the Senior Secured Notes; (f) Borrower and each Subsidiary of Borrower has agreed to guaranty the obligations in respect of the Term Loan and in respect of the Senior Secured Notes; (g) PCI Canada and PCI Carolina has each agreed to transfer its rights in respect of certain license agreements to Licensing; and (h) Borrower and its Subsidiaries intend to consummate certain other transactions in 2 Pioneer Americas Acquisition Corp. November 5, 1997 Page 2 connection with the foregoing (all of the foregoing being collectively referred to as the "Transactions"). Consummation of the Transactions would violate various provisions of the Loan Agreement. Consequently, Borrower has requested that Agent and Lenders consent to the consummation of the Transactions. Borrower has also requested that Agent and Lenders agree to amend the Loan Agreement in certain respects in order to (i) increase the Revolving Credit Amount from $35,000,000 to $65,000,000; (ii) add PCI Canada as a borrowing entity thereunder; (iii) provide for loans in Canadian Dollars; (iv) add Kemwater North America, Inc. as a borrower thereunder; (v) accept Borrower's designation of PCI Canada, PCI Carolina and Licensing as Designated Subsidiaries thereunder; and (vi) extend the term thereof, amend the interest rates and fees payable in connection therewith, amend the financial covenants contained therein and otherwise revise and amend the Loan Agreement in various respects. In connection with such requests, Agent and its affiliate, BancAmerica Robertson Stephens ("BRS"), have issued a certain commitment letter dated October 10, 1997 and accepted by Borrower on October 17, 1997 (the "Commitment Letter"), which Commitment Letter describes the terms on which Agent and Lenders have agreed to amend the Loan Agreement. A copy of the Commitment Letter is attached hereto as Exhibit B. Borrower and Agent have agreed that it will not be possible to consummate the amendments described in the Commitment Letter prior to the scheduled closing of the Transactions on November 5, 1997. Consequently, Borrower has requested that Agent and Lenders (x) enter into an amendment to the Loan Agreement that increases the Revolving Credit Amount thereunder to $65,000,000, adds PCI Canada as a borrowing entity thereunder (subject to satisfaction of certain conditions prior to Loans actually being made available to PCI Canada), amends the interest charges and fees payable in connection with the Loans and accepts the designation of PCI Canada, PCI Carolina and Licensing as Designated Subsidiaries and (y) agree with Borrower that after consummation of the Transactions, Agent and Lenders will negotiate with Borrower an Amended and Restated Loan and Security Agreement (the "Amended Agreement") and related agreements, instruments and documents, that collectively will effect the financing terms described in the Commitment Letter. Agent and Lenders have agreed to all of the foregoing on the terms described herein. 3 Pioneer Americas Acquisition Corp. November 5, 1997 Page 3 2. Consent.
