3.2 Special Allocations. The following special allocations shall be made in the following order:

(a) Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(f), notwithstanding any other provision of this Section 3, if there is a net decrease in Partnership Minimum Gain during any fiscal year, each Partner and Interest Holder shall be specially allocated items of Partnership income and gain for such fiscal year (and, if necessary, subsequent fiscal years) in an amount equal to such Partner’s and Interest Holder’s share of the net decrease in Partnership Minimum Gain, determined in accordance with Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner and Interest Holder pursuant thereto.

This Section 3.2(a) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

(b) Partner Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this Section 3, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any fiscal year, each Partner and Interest Holder who has a share of the Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Partnership income and gain for such fiscal year (and, if necessary, subsequent fiscal years) in an amount equal to such Partner’s and Interest Holder’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner and Interest Holder pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 3.2(b) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c) Qualified Income Offset. In the event any Partner or Interest Holder unexpectedly receives any adjustments, allocations, or distributions described in Regulations Sections 1.704- 1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specially allocated to each such Interest Holder in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Interest Holder as quickly as possible; provided that an allocation pursuant to this Section 3.2(c) shall be made only if and to the extent that such Interest Holder would have an Adjusted Capital Account Deficit after all other allocations provided for in this Section 3 have been tentatively made as if this Section 3.2(c) were not in the Agreement. This Section 3.2(c) is intended to comply with the qualified income offset requirement in Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(d) Gross Income Allocation. In the event any Partner or Interest Holder has an Adjusted Capital Account Deficit at the end of any fiscal year which is in excess of the sum of (i) the amount such Interest Holder is obligated to restore pursuant to any provision of this Agreement, and (ii) the amount such Interest Holder is deemed to be obligated to restore pursuant to the penultimate sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Interest Holder shall be specially allocated items of Partnership income and gain in the

amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 3.2(d) shall be made only if and to the extent that such Interest Holder would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Section 3 have been made as if Section 3.2(c) hereof and this Section 3.2(d) were not in the Agreement.

(e) Nonrecourse Deductions. Nonrecourse Deductions for any fiscal year or other period shall be specially allocated among the Partners and Interest Holders pro rata in accordance with their respective Percentage Interests.

Any Partner Nonrecourse Deductions for any fiscal year or other period shall be specially allocated to the Partner or Interest Holder who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Regulations Section 1.704-2(i)(1).

(g) Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) (including any such adjustments pursuant to Regulations Section 1.734-2(b)(1)) is required, pursuant to Regulations Sections 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Partners and Interest Holders in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Regulations.

3.3 Curative Allocations.

The allocations set forth in Sections 3.1(b) and 3.2 hereof (collectively, the “Regulatory Allocations”) are intended to comply with the requirements of the Regulations. It is the intent of the parties hereto that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Partnership income, gain, loss, or deduction pursuant to this Section 3.3. Therefore, notwithstanding any other provision of Section 3 (other than the Regulatory Allocations), the Partnership Committee shall make such offsetting special allocations of Partnership income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s or Interest Holder’s Capital Account balance is, to the extent possible, equal to the Capital Account such Person would have had if the Regulatory Allocations were not terms of this Agreement and all Partnership items were allocated pursuant to Section 3.1(a). In exercising its discretion under this Section 3.3, the Partnership Committee shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made.

3.4 Other Allocation Rules.

(a) For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such other items shall be determined on a daily,

monthly’ or other basis, as determined by the Partnership Committee using any permissible method under Code Section 706 and the Regulations thereunder.

(b) Except as otherwise provided in this Agreement, all items of Partnership income, gain, loss, deduction, and any other allocations not otherwise provided for shall be divided among the Partners and Interest Holders in the same proportions as they share Profits or Losses, as the case may be, for the year.

(c) The Partners are aware of the income tax consequences of the allocations made by this Section 3 and hereby agree to be bound by the provisions of this Section 3 in reporting their shares of Partnership income and loss for income tax purposes.

(d) Solely for purposes of determining a Partner’s or Interest Holder’s proportionate share of the “excess nonrecourse liabilities” of the Partnership within the meaning of Regulations Section 1.752-3(a)(3), if any, such excess nonrecourse liability shall be allocated to the Partners or Interest Holders as follows:

(i) First, such excess nonrecourse liabilities shall be allocated to the Partners and Interest Holders up to the amount of built-in gain allocable to such Person on Code Section 704(c) property (as defined in Regulations Section 1.704-3(a)(3)(i)) or property for which reverse Code Section 704(c) allocations are applicable (as described in Regulations Section 1.704-3(a)(6)(i)) where such property is subject to the nonrecourse liability, to the extent such gain exceeds the gain described in Regulations Section 1.752-3(a)(2).

(ii) Second, the balance of such excess nonrecourse liabilities, if any, shall be allocated to the Partners and Interest Holders in accordance with their Percentage Interests.

(e) To the extent permitted by Regulations Sections 1.704-2(h) and 1.704-2(i)(6), the Partnership Committee shall endeavor to treat distributions of Available Cash as having been made from the proceeds of a Nonrecourse Liability or a Partner Nonrecourse Debt only to the extent that such distributions would cause or increase an Adjusted Capital Account Deficit for any Interest Holder.

3.5 Tax Allocations: Code Section 704(c).

In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Partnership shall, solely for tax purposes, be determined and allocated among the Partners and Interest Holders under the rules prescribed by Regulations Section 1.704-3(d)(2) so as to take account of any variation between the adjusted basis of such property to the Partnership for federal income tax purposes and its initial Gross Asset Value (computed in accordance with Section 1.7(o)(i) hereof).

In the event the Gross Asset Value of any Partnership asset is adjusted pursuant to Section 1.7(o)(ii) hereof, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset

for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and under the rules prescribed by Regulations Section 1.704-3(d)(2).

Any elections or other decisions relating to such allocations shall be made by the Partnership Committee in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 3.5 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Person’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

SECTION 4
DISTRIBUTIONS

4.1 Quarterly Distributions. Except as otherwise provided in Section 12 hereof, Available Cash, if any, shall be distributed quarterly in the following order and priority:

(a) First, to the Partners, in proportion to the total amount distributable to each such Partner pursuant to this Section 4.1(a), until each such Partner receives an amount equal to the excess, if any, of (i) the cumulative additional Capital Contributions made by such Partner pursuant to Section 2.3(a) hereof from the date hereof to the end of the quarter preceding the quarter during which such distribution is made, over (ii) the sum of all prior distributions to such Partner pursuant to this Section 4.1(a) during that same period; and

(b) The balance, if any, to the Partners pro rata in accordance with their respective Percentage Interests.

4.2 Amounts Withheld. All amounts withheld during any fiscal year pursuant to the Code or any provision of any state or local tax law with respect to any payment, distribution or allocation to the Partnership, the Partners or the Interest Holders shall be treated for all purposes under this Agreement as amounts distributed pursuant to this Section 4 to the Partners and the Interest Holders with respect to which such amounts are withheld, and shall reduce amounts otherwise distributable to each such Partner during such period, provided that, if the amounts required to be withheld with respect to each Partner or Interest Holder during such period exceed the amounts otherwise distributable to such Partner or Interest Holder during such period, such Partner or Interest Holder shall contribute to the Partnership an amount equal to such excess upon demand by OCI. The Partnership Committee is authorized to withhold from distributions, or with respect to allocations, to the Partners and Interest Holders and to pay over to any federal, state, or local government any amounts required to be so withheld pursuant to the Code or any provisions of any other federal, state, or local law, and may allocate any such amounts among the Partners and Interest Holders in any manner that is in accordance with applicable law.

(a) To the fullest extent permitted by applicable law, each Representative, Officer and Indemnified Person (and their respective heirs, executors and administrators) shall be indemnified by the Partnership (and any receiver, liquidator or trustee of, or successor to, the Partnership) from and against any and all liabilities, obligations, losses, damages, penalties, costs or expenses (including, without limitation, all costs and expenses of defense, appeal or settlement reasonably incurred by or imposed upon him) in connection with or arising out of any action, suit or proceeding in which he may be involved and which relates in any way to the Partnership or its business and assets, or to which he may be made a party by reason of his being or having been a Representative or Officer of the Partnership or, at its request, a partner or officer of any partnership or corporation of which it is a partner, stockholder or creditor and for which he is not entitled to be indemnified (whether or not he continues to be a Representative, Officer or Indemnified Person at the time of imposing or incurring such expenses); provided, however, that no indemnification shall be provided hereunder in respect of matters as to which he shall be finally adjudged in such action, suit or proceeding to be liable for breach of any duty expressly imposed by this Agreement; intentional misconduct; a knowing violation of law; or any transaction from which such Representative, Officer or Indemnified Person derived an improper personal benefit. With respect to any criminal action or proceeding, no indemnification shall be provided hereunder if such Representative, Officer or Indemnified Person had reasonable cause to believe that his or her conduct was unlawful. In the event of a settlement of any such action, suit or proceeding, indemnification shall be provided only in connection with such matters covered by the settlement as to which the Partnership is advised by counsel that the person to be indemnified did not commit a breach of duty; intentional misconduct; a knowing violation of law; derive an improper personal benefit from a transaction; or have reasonable cause to believe that his or her conduct was unlawful. Notwithstanding the foregoing, no indemnification shall be provided hereunder in respect of any claim by the Partnership or any Partner against a Representative, Officer or Indemnified Person other than a claim for costs and expenses of defense, appeal and settlement reasonably incurred by or imposed on him and otherwise indemnifiable hereunder. The foregoing right of indemnification shall not be exclusive of other rights to which he may be entitled.

(b) The Partnership shall pay expenses as they are incurred by any Indemnified Person, Representative or Officer in connection with any action, claim, or proceeding that the Indemnified Person, Representative or Officer asserts in good faith to be subject to the indemnification obligations set forth herein, upon receipt of an undertaking from

such Indemnified Person, Representative or Officer to repay all amounts so paid by the Partnership to the extent that it is finally determined that the Indemnified Person, Representative or Officer is not entitled to be indemnified therefor under the terms hereof.

(c) If a claim for indemnification or payment of expenses hereunder is not paid in full within ten days after a written claim therefor has been received by the Partnership, the claimant may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Partnership shall have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under applicable law.

5.6 Day-to-Day Management: Staffing.

it being agreed, however, that to the extent any reimbursable costs or expenses incurred by OCI (and/or its Affiliates) consist of an allocated portion of costs and expenses incurred by OCI (and/or its Affiliates) for the benefit of both the Partnership and OCI (and/or its Affiliates), such allocation shall be made on a reasonable cost reimbursement basis as determined by OCI (and/or its Affiliates).

5.7 Loans.

Except as provided in Sections 5.8(a)(iii) and 5.8(a)(iv) hereof, the approval of the Partnership Committee shall be required prior to any action that is materially inconsistent with any current Budget or Program.

(i) In accordance with Section 8.4 hereof and Exhibit A hereto, OCI will prepare and provide to the Partners an annual budget and a three-year plan setting forth such assumptions and forecasts as are required to review the status of the business and determine future capital requirements (such annual plan and three-year plan herein referred to together as the “Budget”). OCI shall prepare and provide to the Partners “Programs” for all planned capital expenditures whether or not such capital expenditures were specifically described in the Budget. Such “Programs” shall be presented with description, justification, and spending plans in the form customarily used by OCI Enterprises, Inc.

(iv) Notwithstanding anything to the contrary in this Agreement, the Partnership Committee and the Resident Plant Manager shall have the right to take actions that are materially inconsistent with any current Budget or Programs if any of them, in their reasonable judgment, deems such action necessary for the protection of life or health or the preservation of Partnership assets and if, under the circumstances, in the good faith estimation of any of them, there is insufficient time to allow the Partners to review such action in accordance with Section 5.8(a)(ii) hereof and any delay would materially increase the risk to life or health or the preservation of Partnership assets. Either the Partnership Committee or the Resident Plant Manager shall notify the Partners of each such action contemporaneously therewith or as soon as reasonably practical thereafter. Such authority shall lapse and terminate upon reduction of such risk to life or health or preservation of assets.

(v) The Partnership Committee and OCI shall promptly advise and inform the Partners of any transaction, notice, event, or proposal directly relating to the management and operation of the Partnership’s business which does or could affect, either

SECTION 10
TRANSFERS OF INTERESTS

10.1 Restriction on Transfers. No Partner or Interest Holder shall Transfer any of its Interest in the Partnership save as provided in this Section 10 and subject to the restriction regarding the Transfer of a General Partner’s Interest as a General Partner provided in Section 11 hereof. No Ultimate Parent shall Transfer or cause or permit to be Transferred any portion of its interest in any Person 80% of the fair market value of the assets of which, whether held directly or indirectly, consist of an Interest in the Partnership unless (i) after such Transfer, such Partnership Interest shall continue to be held by an Affiliate of such Ultimate Parent described in Section 1.7(c)(i) hereof, or (ii) prior to such transfer, such Partnership Interest shall have been Transferred in a Permitted Transfer.

10.2 Permitted Transfers. Subject to the conditions and restrictions set forth in Section 10.3 hereof, any Partner or Interest Holder may at any time Transfer all or any portion of its Interests to (a) any Affiliate of the transferor described in Section l.7(c)(i) hereof or, (b) any Purchaser in accordance with Section 10.4 hereof (any such Transfer being referred to in this Agreement as a “Permitted Transfer”) or (c) the lenders (or the administrative agent or collateral agent therefor) under the OCI Credit Facility in connection with the pledge of Interests thereunder (or the exercise or remedies with respect thereto).

10.3 Conditions to Permitted Transfers. A Transfer shall not be treated as a Permitted Transfer under Section 10.2 hereof unless and until the following conditions are satisfied:

(a) Except in the case of a Transfer of Interests involuntarily by operation of law, the transferor and transferee shall execute and deliver to the Partnership such documents and instruments of conveyance as may be necessary or appropriate in the opinion of counsel to the Partnership to effect such Transfer and to confirm the agreement of the transferee to be bound by the provisions of this Section 10. In the case of a Transfer of Interests involuntarily by operation of law, the Transfer shall be confirmed by presentation to the Partnership of legal evidence of such Transfer, in form and substance satisfactory to counsel to the Partnership.

(b) Except in the case of a Transfer involuntarily by operation of law, the transferor shall furnish to the Partnership an opinion of counsel, which counsel and opinion shall be satisfactory to the Partnership, that the Transfer will not cause the Partnership to terminate for federal income tax purposes.

(c) The transferor and transferee shall furnish the Partnership with the transferee’s taxpayer identification number, sufficient information to determine the transferee’s initial tax basis in the Interests transferred, and any other information reasonably necessary to permit the Partnership to file all required federal and state tax returns and other legally required

information statements or returns. Without limiting the generality of the foregoing, the Partnership shall not be required to make any distribution otherwise provided for in this Agreement with respect to any transferred Interests until it has received such information.

(d) In the case of a Transfer of a Limited Partner’s Interest, the transferor must obtain the prior consent of all Partners to such Transfer.

10.4 Right of First Refusal. In addition to the other limitations and restrictions set forth in this Section 10, except as permitted by Section 10.2(a) hereof, no Partner or Interest Holder shall Transfer all or any portion of its Interests (the “Offered Interest”) unless such Partner or Interest Holder first offers to sell the Offered Interest pursuant to the terms of this Section 10.4, provided that, notwithstanding anything to the contrary herein, no Transfer arising out of the pledge of any Interest (including the exercise of remedies with respect to such pledge) by OCI pursuant to the OCI Credit Facility shall be subject to this Section 10.4.

(a) In General. Should any Partner or Interest Holder (the “Seller”) propose to transfer any of its Interest in the Partnership, such Seller shall first obtain a bona fide written offer (the “Purchase Offer”) for the purchase thereof from a responsible purchaser (the “Purchaser”) who is ready, willing and able to purchase the same, which offer shall provide for a purchase price payable in cash of the lawful money of the United States of America or other “hard” currency. The Seller shall give the other Partners (the “Offerees”) written notice by registered or certified mail, the notice to be accompanied by a photostatic copy of such Purchase Offer. Such notice shall specify the Percentage Interest to be transferred (the “Offered Interest”), the name of the proposed purchaser, and the price for which such Offered Interest is proposed to be transferred. In the event such notice is given, then the Offerees shall have 30 days within which to elect to purchase the Offered Interest at the price and on the terms specified in said offer, provided that payment may be made in cash of the lawful money of the United States of America or other “hard” currency provided that the value of such payment equals the price specified in the Purchase Offer. Each Offeree shall have the option to purchase that portion of the Offered Interest as corresponds to a fraction, the numerator of which is such Offeree’s Percentage Interest, and the denominator of which is the aggregate Percentage Interests held by Offerees. In the event either Offeree shall not elect to purchase its entire pro rata share, such share not purchased may be purchased by the other Offeree. An election shall be made by giving written notice to the Seller within said 30-day period by registered or certified mail stating the portion of the Offered Interest that such Offeree is willing to purchase. The Offerees electing to purchase the Offered Interest shall have 15 days after giving notice of such election to consummate such purchase. If the Seller shall give notice to the Offerees as herein required, and the Offerees shall not elect to purchase the entire Offered Interest within such 30-day period or shall fail to consummate such purchase within 15 days after such election, the Offered Interest may thereafter be transferred to said Purchaser.

(b) Pledges. In the event that any Partner or Interest Holder (the “Pledgor”) shall desire to pledge or otherwise encumber any of its Interest in the Partnership as security for the payment of a debt, such Pledgor shall give written notice of the pledging or hypothecation of such Interest to the other Partners by giving written notice thereof by registered or certified mail to the other Partners within 10 days after the making of the agreement pledging or hypothecating said Interest. Any such pledge or hypothecation agreement shall require the

pledgee or party secured to assume and be bound by all of the obligations, terms and conditions of this Agreement. No such pledge or hypothecation agreement shall be made unless it shall provide that any sale of the Interest so pledged or hypothecated pursuant to the provisions of said pledge or hypothecation agreement shall be at public sale and after thirty (30) days’ notice shall have been given to the other Partners by registered or certified mail of such sale. In the event any Pledgor shall have pledged or hypothecated any of its Interest in the Partnership and is unable or unwilling to redeem the same as provided for in the pledge or hypothecation agreement, such Pledgor agrees to notify the Partners of its inability or unwillingness to redeem at least ten (10) days before the maturity of the pledge or hypothecation agreement and hereby, agrees to give to the Partners the right to redeem the pledged Interest in the same proportions as such Partners could have elected to purchase the pledged Interest pursuant to Section 10.4(a) hereof had it been an Offered Interest. In the event the Partners shall redeem the Interest so pledged or hypothecated, the Pledgor who originally pledged or hypothecated said Interest shall, without further consideration, promptly execute and deliver to the Partners all documents required to transfer to them the ownership of the Interest so pledged or hypothecated.

10.5 Involuntary Transfers. In the event that any Partner or Interest Holder shall become a party to any proceeding or be subject to any legal process, the purpose of which is to require the involuntary transfer of any portion of the Interest in the Partnership of such Partner, such Partner shall immediately give notice by wire to the other of such Partners of the existence or pendency of such legal proceeding or legal process.

10.6 Admission of Transferees as Partners. Subject to the other provisions of this Section 10, a transferee of an Interest in the Partnership may be admitted to the Partnership as a substituted Partner only upon satisfaction of the conditions set forth below in this Section 10.6:

(a) The Interests with respect to which the transferee is being admitted were acquired by means of a Permitted Transfer or in the circumstances described in Section 10.2(c);

(b) The transferee becomes a party to this Agreement as a Partner and executes such documents and instruments as the Partnership Committee may reasonably request (including, without limitation, amendments to the Certificate) and as may be necessary or appropriate to confirm such transferee as a Partner in the Partnership and such transferee’s agreement to be bound by the terms and conditions hereof;

(c) If the transferee is a Person other than an individual, the transferee provides the Partnership with evidence satisfactory to counsel for the Partnership that such transferee has made each of the representations and undertaken each of the warranties described in Section 7 hereof; and

(d) A transferee of an Interest from a Limited Partner hereunder shall be admitted as a Limited Partner with respect to such Interest if, but only if, all of the other Partners consent to such admission.

10.7 Rights of Unadmitted Assignees. A person who acquires one or more Interests but who is not admitted as a substituted Partner pursuant to Section 10.6 and Section 11.2(b) hereof shall be entitled only to allocations and distributions with respect to such Interests in accordance with this Agreement, but shall have no right to any information or accounting of the affairs of the Partnership, shall not be entitled to inspect the books or records of the Partnership, and shall not have any of the rights of a General Partner or a Limited Partner under the Act or this Agreement.

10.8 Transfer Procedures.

(a) Transfer Books. The Partnership Committee may close the transfer books of the Partnership for a period not exceeding 50 days preceding the date of any meeting of Partners or the date for any distribution pursuant to Section 4 hereof or the date for the allotment of rights or for a period of not exceeding 50 days in connection with obtaining the consent of Partners for any purpose. In lieu of closing the transfer books as aforesaid, the Partnership Committee may fix in advance a date, not exceeding 50 days preceding the date of any meeting of Partners, or the date for making any distribution, or the date for the allotment of rights, or a date in connection with obtaining such consent, as a record date for the determination of the Partners entitled to notice of, and to vote at, any such meeting, and any adjournment thereof, or entitled to receive any such distribution, or to any such allotment of rights, or to give such consent, and in such case such Partners and only such Partners as shall be Partners of record on the date so fixed shall be entitled to such notice of, and to vote at, such meeting and any adjournment thereof, or to receive such distribution, or to receive such allotment of rights, or to exercise such rights, or to give such consent, as the case may be, notwithstanding any transfer of any Interest in the Partnership on the books of the Partnership after any such record date fixed as aforesaid.

(b) Holders of Record. The Partnership shall be entitled to treat the holder of record of any Interest in the Partnership as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Interest in the Partnership on the part of any other Person, whether or not it shall have express or other notice thereof, except as otherwise provided by the Act.

SECTION 11
GENERAL PARTNERS

11.1 Covenant Not to Withdraw, Transfer, or Dissolve. Except as otherwise permitted by this Agreement, each of the General Partners hereby covenants and agrees not to (a) take any action to file a certificate of dissolution or its equivalent with respect to itself, (b) take any action that would cause a Voluntary Bankruptcy of the General Partner, (c) withdraw or attempt to withdraw from the Partnership, (d) exercise any power under the Act to dissolve the Partnership, (e) transfer all or any portion of its Interest in the Partnership as a General Partner, or (f) petition for judicial dissolution of the Partnership. Further, each of the General Partners hereby covenants and agrees to continue to carry out the duties of a General Partner hereunder until the Partnership is dissolved and liquidated pursuant to Section 12 hereof.

11.2 Conditions to Permitted Transfers; Substitution.

(a) Each of the General Partners may transfer, assign, encumber, pledge or in any way alienate any of its Interest in the Partnership as a General Partner in accordance with Section 10 hereof; provided that the transferor and transferee provide the Partnership with an opinion of counsel, which opinion of counsel shall be acceptable to the other Partners, to the effect that such Transfer will not cause the Partnership to be treated as an association taxable as a corporation for federal income tax purposes, or to fail to meet any condition precedent then in effect pursuant to an official pronouncement of the Internal Revenue Service to the issuance of a private letter ruling by the Internal Revenue Service confirming that the Partnership will be treated as a Partnership for federal tax purposes, whether or not such a ruling is being or has been requested.

(b) A transferee of a Partnership Interest from a General Partner hereunder shall be admitted as a General Partner with respect to such Interest if, but only if, all of the other Partners consent to such admission, provided that no such consent shall be required with respect to the Transfer by OCI of its Interests in connection with the pledge thereof pursuant to the OCI Credit Facility. In the event that the transferee of a Partnership Interest from a General Partner is admitted hereunder, such transferee shall be deemed admitted to the Partnership as a General Partner immediately prior to the Transfer, and such transferee shall continue the business of the Partnership without dissolution.

(c) A transferee who acquires a Partnership Interest from a General Partner hereunder by means of a transfer that is permitted under Section 10 and this Section 11.2, but who is not admitted as a General Partner, shall have no authority to act for or bind the Partnership, to inspect the Partnership’s books, or otherwise to be treated as a General Partner, but such transferee shall be treated as an unadmitted assignee in accordance with Section 10.7 hereof. Following such a Transfer, the transferor shall not cease to be a general partner of the Partnership and shall continue to be a General Partner.

11.3 Termination of Status as General Partner.

(a) A General Partner shall cease to be a General Partner upon the first to occur of (i) the Bankruptcy of such Partner; (ii) the Transfer of such Partner’s Interest as a General Partner; provided that the transferee of such Interest is admitted as a substituted General Partner pursuant to Section 11.2(b) hereof; (iii) the involuntary Transfer by operation of law of such General Partner’s Interest in the Partnership, (iv) after such General Partner has committed a material breach of this Agreement, or committed any other act or suffered any other condition, in each case that would justify a decree of dissolution of the Partnership under the laws of the State of Delaware. In the event a Person ceases to be a General Partner without having transferred its entire Interest as a General Partner, such Person shall be treated as an unadmitted assignee of a Partnership Interest in accordance with Section 10.7 hereof.

If a General Partner ceases to be a Partner for any reason hereunder, such Person shall continue to be liable as a Partner for all debts and obligations of the Partnership existing at the time such Person ceases to be a General Partner, regardless of whether, at such time, such debts or liabilities were known or unknown, actual or contingent. A Person shall not be liable as a General Partner for Partnership debts and obligations arising after such Person ceases to be a General Partner. Any debts, obligations, or liabilities in damages to the Partnership of any

Person who ceases to be a General Partner shall be collectible by any legal means and the Partnership is authorized, in addition to any other remedies at law or in equity, to apply any amounts otherwise distributable or payable by the Partnership to such Person to satisfy such debts, obligations, or liabilities.

(b) It is the intention of the Partners that the Partnership not dissolve as a result of the cessation of any General Partner’s status as a General Partner; provided, however, that if it is determined by a court of competent jurisdiction that the Partnership has dissolved, the provisions of Section 12.1 shall govern.

(c) If at the time a Person ceases to be a General Partner such Person is also a Limited Partner or an Interest Holder with respect to Interests other than its Interest as a General Partner, such cessation shall not affect such Person’s rights and obligations with respect to such Interests.

SECTION 12
DISSOLUTION AND WINDING UP

12.1 Liquidating Events. The Partnership shall dissolve and commence winding up and liquidating upon the first to occur of any of the following (“Liquidating Events”):

(a) The vote of the Partners as required by under the Act to dissolve, wind up and liquidate the Partnership;

(b) The finding by the Partnership Committee or the issuance of a judicial determination that any event has occurred that makes it unlawful, impossible or impractical to carry on the business of the Partnership; or

(c) The withdrawal or removal of a General Partner, the assignment by a General Partner of its entire Interest in the Partnership or any other event that causes a General Partner to cease to be a general partner under the Act, provided that any such event shall not constitute a Liquidating Event if the Partnership is continued pursuant to this Section 12.1.

The Partners hereby agree that, notwithstanding any provision of the Act or the Delaware Uniform Partnership Act, the Partnership shall not dissolve prior to the occurrence of a Liquidating Event. Upon the occurrence of any event set forth in Section 12.1(c), the Partnership shall not be dissolved or required to be wound up if (x) at the time of such event there is at least one remaining General Partner and that General Partner carries on the business of the Partnership (any such remaining General Partner being hereby authorized to carry on the business of the Partnership), or (y) within ninety (90) days after such event all remaining Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of the date of such event, of one or more substitute or additional General Partners. If it is determined, by a court of competent jurisdiction, that the Partnership has dissolved prior to the occurrence of a Liquidating Event, or if upon the occurrence of an event specified in Section 12.1(c) hereof, the Partners fail to agree to continue the business of the Partnership as provided in this Section 12.1, then within an additional 90 days, a 2/3 majority in interest of the Partners may elect to reconstitute the Partnership and continue its business on the same terms and conditions set forth

in this Agreement by forming a new limited partnership on terms identical to those set forth in this Agreement and having as a general partner a Person elected by such 2/3 majority in interest. Upon any such election by a 2/3 majority in interest of the Partners, all Partners shall be bound thereby and shall be deemed to have consented thereto. Unless such an election is made within 180 days after the event causing dissolution, the Partnership shall wind up its affairs in accordance with Section 12.2 hereof. If such an election is made within 180 days after the event causing dissolution, then:

(a) The reconstituted limited partnership shall continue until the occurrence of a Liquidating Event as provided in this Section 12.1;

(b) If the successor general partner is not a former General Partner, then the Interest of any former General Partner shall be treated thenceforth as the Interest of an Interest Holder; and

(c) All necessary steps shall be taken to cancel this Agreement and the Certificate and to enter into a new partnership agreement and certificate of limited partnership; provided that the right of a two-thirds (2/3) majority in interest of the Partners to select a successor general partner and to reconstitute and continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an opinion of counsel that the exercise of the right would not result in the loss of limited liability of any Limited Partner and neither the Partnership nor the reconstituted Partnership would cease to be treated as a partnership for federal income tax purposes upon the exercise of such right to continue.

12.2 Winding Up. Upon the occurrence of a Liquidating Event, the Partnership shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Partners and no Partner shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Partnership’s business and affairs, provided that, all covenants contained in this Agreement and obligations provided for in this Agreement shall continue to be fully binding upon the Partners until such time as the Partnership Property has been distributed pursuant to this Section 12.2 and the Certificate has been cancelled pursuant to the Act. The Partnership Committee, or if the Partnership Committee shall not exist or it shall not be possible for the Partnership Committee to establish a quorum, such other liquidating trustee(s) as are appointed in accordance with the Act shall be the Liquidator. The Liquidator shall be responsible for overseeing the winding up and dissolution of the Partnership and shall take full account of the Partnership’s liabilities and Property and, to the extent determined by the Liquidator, the Property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom together with any remaining Property, to the extent sufficient therefor, shall be applied and distributed in the following order:

(a) First, to the payment and discharge of all of the Partnership’s debts and liabilities to creditors other than the Partners;

(b) Second, to the payment and discharge of all of the Partnership’s debts and liabilities to the Partners; and

(c) The balance, if any, to the Partners and Interest Holders in accordance with their Capital Accounts, after giving effect to all contributions, distributions, and allocations for all periods.

(d) The Partners understand and agree that by accepting the provisions of this Section 12.2 setting forth the priority of the distribution of the assets of the Partnership to be made upon its liquidation, the Partners expressly waive any right which they, as creditors of the Partnership, might otherwise have under the Act to receive a distribution of assets pari passu with other creditors of the Partnership in connection with a distribution of assets of the Partnership in satisfaction of liabilities of the Partnership, and hereby subordinate to said creditors any such right.

12.3 Notice of Dissolution. In the event a Liquidating Event occurs or an event occurs that would, but for provisions of Section 12.1, result in a dissolution of the Partnership, the Partnership Committee shall, within 30 days thereafter, provide written notice thereof to each of the Partners and to all other parties with whom the Partnership regularly conducts business (as determined in the discretion of the Partnership Committee) and shall publish notice thereof in a newspaper of general circulation in each place in which the Partnership regularly conducts business (as determined in the discretion of the Partnership Committee).

SECTION 13
MISCELLANEOUS

13.1 Notices.

(a) Whenever under the provisions of this Agreement or the Act notice is required to be given to any person, it shall not be construed to mean personal notice, but such notice may be given in writing, by registered mail, addressed to such person at such address as appears on the books of the Partnership, and such notice shall be deemed to be given at the time when the same shall be thus mailed. Notice to Representatives may also be given by telegram.

(b) Whenever any notice is required to be given under the provisions of this Agreement or the Act, a waiver thereof in writing signed by the person or persons entitled to said notice, whether before or after the time stated therein, shall be deemed equivalent thereto.

13.2 Headings. Section and other headings contained in this Agreement are for reference purposes only and are not intended to describe, interpret, define, or limit the scope, extent, or intent of this Agreement or any provision hereof.

13.3 Variation of Pronouns. All pronouns and any variations thereof shall be deemed to refer to masculine, feminine, or neuter, singular or plural, as the identity of the person or persons may require.

13.4 Governing Law. The laws of the State of Delaware (without regard to the choice of law principles thereof) shall govern the validity of this Agreement, the construction of its terms, and the interpretation of the rights and duties of the Partners.

Each of the Partners irrevocably waives any right that it may have to maintain any action for partition with respect to any of the Partnership Property. To the fullest extent permitted by law, each of the Partners covenants that it will not (except with the consent of the Partnership Committee) file a xxxx for Partnership accounting.

13.6 Implementation. Each of the Partners agrees to promptly execute all instruments and to promptly do all other things necessary for the effectuation and implementation of this Agreement.

13.9 Initial Public Offering of OCI Resources LP and Exchange Act Reporting. Notwithstanding anything herein to the contrary, no consent or approval of any Partner or the Partnership Committee shall be required in connection with the initial public offering of common units representing limited partner interests (the “OCI Units”) in OCI pursuant to the Registration Statement on Form S-1 (Registration No. 333-189838) (the “IPO”) and/or any subsequent transfer or issuance of such OCI Units to one or more third parties; provided that OCI Enterprises, Inc., either alone or together with one or more of its Affiliates, directly or indirectly controls the management and policies of OCI after such transfer or issuance, and such initial public offering (and subsequent transfers or issuances of OCI Units) shall not be subject to Section 10 or Section 11 of this Agreement nor cause any Partner to have any rights or obligations under Section 10 or Section 11 of this Agreement. The parties hereto agree that the Transfer by OCI Co. of its limited partnership interests in the Partnership to OCI contemporaneously with the IPO is a Permitted Transfer to an Affiliate pursuant to Section 10.2(a) and each of the Partners hereby consents to such Transfer pursuant to Section 10.3(d). In addition, notwithstanding anything herein to the contrary OCI shall be permitted to file and submit documents or agreements with the Securities and Exchange Commission, applicable securities exchanges and regulatory and self-regulatory organizations and compile, prepare and publicly disclose information regarding the Partnership, this Agreement and any matters related thereto, in each case to the extent required by applicable law, rule or regulation or the rules and regulations of any applicable securities exchange or as reasonably necessary in the view of OCI to conform to customary disclosure practices of other publicly traded master limited partnerships. Each of OCI and NRP TRONA agrees that it or one of its Affiliates shall provide to the other a copy of each of its periodic reports, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K relating to the Partnership or its

business, to be filed by it with the Securities and Exchange Commission two days prior to such filing; provided that each of OCI and NRP TRONA agrees not to use the information contained therein (except for a purpose directly related to the business of the Partnership) and to maintain the confidentiality of any such filing and the contents thereof and further agrees not to provide to any other Person copies of any such filing without the express prior written consent of OCI or NRP TRONA, as applicable; provided that each of OCI and NRP TRONA may provide such report: (i) to its accountants, internal and external auditors, legal counsel and other fiduciaries (who may be Affiliates) as long as any such Person agrees in writing to maintain the confidentiality thereof and not to disclose to any other Person any information contained therein and (ii) to other Persons if and to the extent required by law (including judicial or administrative order) provided that, to the extent legally permissible, OCI or NRP TRONA, as applicable, is given prior notice to enable it to seek a protective order or similar relief. Notwithstanding the foregoing, information generally known to the public, including such periodic reports and all information contained in such reports after they have been filed by OCI or NRP TRONA, as applicable, with the Securities and Exchange Commission, shall not be considered confidential information for purposes of this Agreement and may be provided by OCI or NRP TRONA to any other Person.

13.10 No Commingling of Funds or Accounts. The General Partners shall not commingle the funds and accounts of the Partnership with any of their respective affiliates.

13.11 Incurrence of Debt.

In the event that the Partnership shall enter into any agreement relating to debt for money borrowed, mortgage, deed of trust, guaranty, indemnity bond, surety bond, performance bond, accommodation paper or endorsement not disclosed pursuant to clause (i), (ii) or (iii) of the immediately preceding sentence, each General Partner shall receive reasonably prompt prior notice thereof; provided, however, that nothing contained in this sentence to the contrary shall limit the right of any General Partner to vote against any such transaction pursuant to the Partnership Agreement. It is expressly understood that the Partnership Credit Facility, and any borrowings thereunder, and all indebtedness, capital leases, notes, debentures and bonds existing as of the date hereof and all amendments, restatements, replacements, refinancing or other modifications with respect to and arising from such existing indebtedness, capital leases, notes, debentures and bonds shall not be subject to the restrictions imposed by this Section 13.11.
