(a) The Indemnified Party agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Article II, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim.

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article II, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement for only the payment of money shall be entered into without the consent of the Indemnified Party unless it includes a full release of the Indemnified Party from such claim; provided, further, that no such settlement containing any form of injunctive or similar relief shall be entered into without the prior written consent of the Indemnified Party, which consent shall not be unreasonably delayed or withheld.

(c) The Indemnified Party agrees to cooperate in good faith and in a commercially reasonable manner with the Indemnifying Party with respect to all aspects of the defense of and pursuit of any counterclaims relating to any claims covered by the indemnification under this Article II, including, without limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense and counterclaims, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and counterclaims, the making available to the Indemnifying Party of any employees of the Indemnified Party and the granting to the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party; provided, however, that in connection

therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 2.5. The obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence shall not be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims and pursuit of any counterclaims with respect to any claims covered by the indemnification set forth in this Article II; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense and counterclaims. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense or counterclaim, but the Indemnifying Party shall have the right to retain sole control over such defense and counterclaims so long as the Indemnified Party is still seeking indemnification hereunder.

(d) In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons.

2.6 Limitations Regarding Indemnification.

(b) For the avoidance of doubt, there is no deductible with respect to the indemnification owed by any Indemnifying Party under any portion of this Article II other than that described in Section 2.6(a), and there is no monetary cap on the amount of indemnity coverage provided by any Indemnifying Party under this Article II.

(c) NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IN NO EVENT SHALL ANY PARTY’S INDEMNIFICATION OBLIGATION HEREUNDER COVER OR INCLUDE CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR SIMILAR DAMAGES OR LOST PROFITS (INCLUDING ANY DIMINUTION IN VALUE OF ANY PARTY’S RESPECTIVE INVESTMENT IN THE PARTNERSHIP) SUFFERED, DIRECTLY OR INDIRECTLY, BY ANY OTHER PARTY ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT, EXCEPT AS A REIMBURSEMENT FOR ANY SUCH DAMAGES AS ARE PAID TO A GOVERNMENTAL AUTHORITY OR OTHER THIRD PARTY.

(c) OCI USA shall have sole discretion to include, or cause to be included, in a Combined Return for any Tax any member of the Partnership Group for which inclusion in such Combined Return is elective; provided, however, that the Partnership Group Combined Tax Liability for any period shall not exceed the aggregate of (x) each such elective Group Member’s liability for such Tax for such period, computed as if such Group Member were not included in such Combined Return and (y) the Partnership Group Combined Tax Liability calculated for the Group Members for which inclusion is not elective. OCI USA shall provide pro forma Tax Returns pursuant to Section 5.2(c) of this Agreement to support the calculation of the amount of any decrease in the Partnership Group Combined Tax Liability pursuant to this Section 5.1(c).

(d) References to “taxable period” for any franchise or other doing business Tax shall mean the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such franchise Tax.

5.2 Allocation of Taxes.

(a) For each Tax for each taxable period that includes or begins on or after the Closing Date and for which a Combined Return is filed, the Group Members included in such Combined Return shall be liable to OCI USA for an amount equal to the Partnership Group Combined Tax Liability in respect of such Tax.

(b) With respect to each Tax for each taxable period that includes or begins on or after the Closing Date and for which a member of the Partnership Group is included in a Combined Return, the Partnership Group Combined Tax Liability for such Tax for such taxable period shall be the Tax for such taxable period as determined on a Partnership Group Pro Forma Combined Return prepared:

(i) by including only the Tax Items of the members of the Partnership Group that are included in the Combined Return and computing the liability of the Group Members for such Tax as if such Group Members were included in a separate consolidated or unitary group;

(ii) except as provided in Section 5.2(b)(v) hereof, using all elections, accounting methods and conventions appropriate for the includable Group Members as a stand-alone taxpayer for such period;

(iii) applying the Tax rate in effect for the Combined Return of the Combined Group for such taxable period;

(iv) assuming that the Partnership Group elects not to carry back any net operating losses; and

(v) assuming that the Partnership Group’s utilization of any Tax Attribute carryforward or carryback is limited to the Tax Attributes of the Partnership Group that would be available if the Partnership Group Combined Tax Liability for each taxable period ending after the Closing Date were determined in accordance with this Section 5.2(b).

(c) Not later than 90 days following the date on which a Combined Return is filed with the appropriate Tax Authority, OCI USA shall prepare and deliver to the Partnership the related Partnership Group Pro Forma Combined Return calculating the Partnership Group Combined Tax Liability attributable to the period covered by such filed Combined Return.

(d) OCI USA shall timely pay (or shall cause to be timely paid) any Tax reflected on a Combined Return and hold harmless the Partnership for all liability for such Tax. In the event OCI USA is required to make an estimated payment or deposit of any Tax of any Combined Group which includes any member of the Partnership Group, OCI USA shall calculate the portion, if any, of such estimated payment or deposit attributable to the Partnership Group using a methodology similar to that described in Section 5.2(b) (the “Partnership Group Deposit”) and shall present such calculation to the Partnership. Within five days thereafter, the Partnership shall pay the Partnership Group Deposit to OCI USA. Within 30 days after delivery by OCI USA of a Partnership Group Pro Forma Combined Return to the Partnership calculating the Partnership Group Combined Tax Liability with respect to a Combined Return, the Partnership shall pay to OCI USA such Partnership Group Combined Tax Liability less the amount of any Partnership Group Deposit relating to the same Combined Return.

(e) With respect to any Combined Return for any taxable period beginning on or after the Closing Date, in the event of a change in the treatment of any Tax Item of any member of a Combined Group as a result of a Final Determination, within 30 days following such Final Determination (i) OCI USA shall calculate the change, if any, to the Partnership Group Combined Tax Liability resulting from such change, (ii) OCI USA shall pay any decrease in the Partnership Group Combined Tax Liability to the Partnership and (iii) the Partnership shall pay any increase in the Partnership Group Combined Tax Liability to OCI USA.

5.3 Control of Tax Proceedings; Cooperation and Exchange of Information.

(a) Except as provided in this Section 5.3, OCI USA shall have full responsibility and discretion in handling, settling or contesting any Tax Controversy involving a Tax Return for which it has filing responsibility under this Agreement as well as any Tax Controversy attributable to a Tax Return for any taxable period ending before the Closing Date. The Partnership shall have full responsibility and discretion in handling, settling or contesting any Tax Controversy involving a Tax Return for which it has filing responsibility under this Agreement. Except as otherwise provided in this Section 5.3 and Section 5.11, any costs incurred in handling, settling or contesting any Tax Controversy shall be borne by the Tax Party having full responsibility and discretion thereof.

(b) Each Tax Party shall cooperate fully at such time and to the extent reasonably requested by any other Tax Party in connection with the preparation and filing of any Tax Return or claim for refund, or the conduct of any audit, dispute, proceeding, suit or action concerning

any issues or other matters considered in this Agreement. Such cooperation shall include, without limitation, the following: (i) the retention and provision on demand of Tax Returns, books, records (including those concerning ownership and Tax basis of property which a Tax Party may possess), documentation or other information relating to the Tax Returns, including accompanying schedules, related workpapers and documents relating to rulings or other determinations by Taxing Authorities, until the expiration of the applicable statute of limitations (giving effect to any extension, waiver or mitigation thereof); (ii) the provision of additional information, including an explanation of material provided under clause (i) of this Section 5.3(b), to the extent such information is necessary or reasonably helpful in connection with the foregoing; (iii) the execution of any document that may be necessary or reasonably helpful in connection with the filing of a Tax Return by OCI USA, the Partnership or of their respective Subsidiaries, or in connection with any audit, dispute, proceeding, suit or action and (iv) such Tax Party’s commercially reasonable efforts to obtain any documentation from a Governmental Authority or a third party that may be necessary or reasonably helpful in connection with any of the foregoing.

(c) Each Tax Party shall make its employees and facilities available on a reasonable and mutually convenient basis in connection with any of the foregoing matters.

(d) If any Tax Party fails to provide any information requested pursuant to Section 5.3 hereof within a reasonable period, as determined in good faith by the Tax Party requesting the information, then the requesting Tax Party shall have the right to engage a public accounting firm to gather such information, provided that 30 days’ prior written notice is given to the unresponsive Tax Party. If the unresponsive Tax Party fails to provide the requested information within 30 days of receipt of such notice, then such unresponsive Tax Party shall permit the requesting Tax Party’s public accounting firm full access to all appropriate records or other information as reasonably necessary to comply with this Section 5.3 and shall reimburse the requesting Tax Party or pay directly all costs connected with the requesting Tax Party’s engagement of the public accounting firm.

5.4 Payment Obligations.

(a) Except as otherwise provided under this Agreement, to the extent that the payor Tax Party has a payment obligation to the payee Tax Party pursuant to this Article V, the payee Tax Party shall provide the payor Tax Party with its calculation of the amount of such obligation. The documentation of such calculation shall provide sufficient detail to permit the payor Tax Party to reasonably understand the calculation. All payment obligations shall be made to the payee Tax Party or to the appropriate Tax Authority as specified by the payee Tax Party within 30 days after delivery by the payee Tax Party to the payor Tax Party of written notice of a payment obligation. Any disputes with respect to payment obligations under this Article V shall be resolved in accordance with Section 5.5.

(b) All actions required to be taken by any Tax Party pursuant to this Article V shall be performed within the time prescribed for performance in this Article V, or, if no period is prescribed, such actions shall be performed promptly.

(c) Payments pursuant to this Article V that are not made within the period prescribed therefor in this Article V shall bear interest (compounded daily) from and including the date immediately following the last date of such period through and including the date of payment at a rate equal to the federal short-term rate or rates established pursuant to Section 6621 of the Code for the period during which such payment is due but unpaid.

(d) The Tax Parties to this Article V hereby agree to retain and provide on proper demand by any Tax Authority (subject to any applicable privileges) the books, records, documentation and other information relating to any Tax Return until the later of (i) the expiration of the applicable statute of limitations (giving effect to any extension, waiver or mitigation thereof), (ii) the date specified in an applicable records retention agreement entered into with a Tax Authority, (iii) a Final Determination made with respect to such Tax Return and (iv) the final resolution of any claim made under this Agreement for which such information is relevant.

(e) Each Tax Party agrees (i) not to take any action reasonably expected to result in a new or changed Tax Item that is detrimental to any other Tax Party and (ii) to take any action reasonably requested by any other Tax Party that would reasonably be expected to result in a new or changed Tax Item that produces a benefit or avoids a detriment to such other Tax Party; provided, that such action does not result in any additional cost not fully compensated for by the requesting Tax Party. The Tax Parties hereby acknowledge that the preceding sentence is not intended to limit, and therefore shall not apply to, the rights of the Tax Parties with respect to matters otherwise covered by this Article V.

(f) Except as provided in Section 5.1(c), all payments to be made under this Article V shall be made without setoff, counterclaim or withholding, all of which are expressly waived by the Tax Parties to the fullest extent permitted by applicable law.

5.5 Resolution of Tax Disputes. To the fullest extent permitted by law, any disagreement between the Tax Parties with respect to any matter that is the subject of Article V of this Agreement, including, without limitation, any disagreement with respect to any calculation or other determinations by OCI USA hereunder, which is not resolved by mutual agreement of the Tax Parties, shall be resolved by a nationally recognized independent accounting firm chosen by and mutually acceptable to the Tax Parties hereto (an “Accounting Referee”). Such Accounting Referee shall be chosen by the Tax Parties within 15 business days from the date on which one Tax Party serves written notice on another Tax Party requesting the appointment of an Accounting Referee; provided, that such notice specifically describes the calculations to be considered and resolved by the Accounting Referee. In the event the Tax Parties cannot agree on the selection of an Accounting Referee, then the Accounting Referee shall be any office or branch of the public accounting firm of Deloitte Tax LLP. The Accounting Referee shall resolve any such disagreements as specified in the notice within 30 days of appointment; provided, however, that no Tax Party shall be required to deliver any document or take any other action pursuant to this Section 5.5 if it determines that such action would result in the waiver of any legal privilege or any detriment to its business. To the fullest extent permitted by law, any resolution of an issue submitted to the Accounting Referee shall be final and binding on the Tax Parties hereto without further recourse. The Tax Parties shall share the costs and fees of the Accounting Referee equally. In the event of a conflict between this Section 5.5 and Section 7.2, this Section 5.5 shall control.

5.6 Required Payments. Unless otherwise provided in this Article V, any payment of Tax required shall be due within thirty (30) days of a Final Determination of the amount of such Tax.

5.7 Injunctions. The Tax Parties acknowledge that irreparable damage would occur in the event that any of the provisions of this Article V were not performed in accordance with its specific terms or were otherwise breached. To the fullest extent permitted by applicable law, the Tax Parties hereto shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Article V and to enforce specifically the terms and provisions of this Article V in any court having jurisdiction, such remedy being in addition to any other remedy to which they may be entitled at law or in equity.

5.8 Parties in Interest. Except as herein otherwise specifically provided, nothing in this Article V expressed or implied is intended to confer any right or benefit upon any person, firm or corporation other than the Tax Parties and their respective successors and permitted assigns.

5.9 Change of Law. If, due to any change in applicable law or regulations or the interpretation thereof by any court of law or other Governmental Authority having jurisdiction subsequent to the date of this Agreement, performance of any provision of this Article V or any transaction contemplated thereby shall become impracticable or impossible, the Tax Parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

5.10 Waiver. Any provision of this Article V may be waived if, and only if, such waiver is in writing and signed, and in the case of a waiver, by the Tax Party against whom the waiver is to be effective. No failure or delay by any Tax Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

5.11 Costs, Expenses and Attorneys’ Fees. In the event a Tax Party to this Agreement brings an action or proceeding for the breach or enforcement of this Article V, the prevailing party in such action, proceeding, or appeal, whether or not such action, proceeding or appeal proceeds to final judgment, shall, to the fullest extent permitted by law, be entitled to recover as an element of its costs, and not as damages, such reasonable attorneys’ fees as may be awarded in the action, proceeding or appeal in addition to whatever other relief the prevailing party may be entitled. For purposes of this Section 5.11, the “prevailing party” shall be the Tax Party who is entitled to recover its costs; a Tax Party not entitled to recover its costs shall not recover attorneys’ fees. No sum for attorneys’ fees shall be counted in calculating the amount of the judgment for purposes of determining whether a Tax Party is entitled to recover its costs or reasonable attorneys’ fees.
