(b)    If any claim (an “Indemnified Tax Claim”) is made by any Tax Authority that, if successful, would result in indemnification of any Party (the “Tax Indemnified Party”) by another Party (the “Tax Indemnifying Party”) under this Section 8.3, the Tax Indemnified Party shall promptly, but in no event later than the earlier of (i) 45 days after receipt of notice from the Tax Authority of such claim or (ii) 15 days prior to the date required for the filing of any protest of such claim, notify the Tax Indemnifying Party in writing of such fact.

(c)    The Tax Indemnifying Party (in cooperation with the other members of Whitehall, PDQ and Augusta pursuant to the documents governing the management of the affairs of Whitehall, PDQ and Augusta, respectively) shall control all decisions with respect to any Tax Proceeding involving an Indemnified Tax Claim and the Tax Indemnified Party shall take such action (including settlement with respect to such Tax Proceeding or the prosecution of such Tax Proceeding to a determination in a court or other tribunal of initial or appellate jurisdiction) in connection with a Tax Proceeding involving an Indemnified Tax Claim as the Tax Indemnifying Party shall reasonably request in writing from time to time, including the selection of counsel and experts and the execution of powers of attorney; provided, however, that (i) within 30 days after the notice required by Section 8.3(b) has been delivered (or such earlier date that any payment of Taxes with respect to such claim is due but in no event sooner than five days after the Tax Indemnifying Party’s receipt of such notice), the Tax Indemnifying Party requests that such claim be contested, and (ii) if the Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the Tax claimed and sue for a refund, the Tax Indemnifying Party shall have advanced to the Tax Indemnified Party, on an interest-free basis, the amount of such claim.

(a)    Any Partnership Indemnified Party or Proppants Indemnified Party claiming indemnification under this Agreement (an “Indemnified Party”) with respect to any claim asserted against the Indemnified Party by a third party (“Third Party Claim”) in respect of any matter that is subject to indemnification under Section 10.2 shall promptly (i) notify the Party providing the indemnification hereunder (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim and a copy of all papers served with respect to such claim (if any). Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

(b)    The Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim (unless (i) such Third Party Claim is asserted against the Indemnifying Party also and the Indemnified Party determines in good faith that joint representation would be inappropriate, or (ii) the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its financial capacity to defend such Third Party Claim and provide indemnification with respect to any Losses arising from Third Party Claim). If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third Party Claim, then the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying Party in accordance with this Section 10.3(b) and, after notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such Third Party Claim, the Indemnifying Party will not, as long as it diligently conducts such defense, be liable to the Indemnified Party under this ARTICLE X for any fees of other counsel or any other expenses with respect to the defense of such Third Party Claim, in each case subsequently incurred by the Indemnified Party in connection with the defense of such Third Party Claim, other than reasonable costs of investigation. The Indemnifying Party shall have full control of such defense

and proceedings, including any compromise or settlement thereof; provided, however, that the Indemnifying Party shall not enter into any settlement agreement without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided, further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the third party asserting the claim to all Indemnified Parties affected by the claim, (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates, (iii) there is no finding or admission of any violation of applicable Law or any violation of the rights of any Person and no effect on any other Third Party Claims that may be made against the Indemnified Party, (iv) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and (v) the Indemnified Party will have no liability with respect to any compromise or settlement of such Third Party Claims. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 10.3(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c)    If the Indemnifying Party does not notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 10.3(b), then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified Party, by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 10.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d)    Subject to the other provisions of this ARTICLE X, a claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the Party from whom indemnification is sought.

(e)    The Parties hereby consent to the non-exclusive jurisdiction of any court in which a Proceeding is brought against any Indemnified Party for purposes of any Claim that an Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agree that process may be served on any Party with respect to such a claim anywhere in the world.

(f)    The Indemnified Party or the Indemnifying Party, as the case may be, shall furnish such information (so long as such information is not subject to any confidentiality agreements or attorney-client privilege; provided, that the parties shall take all reasonable measures to fully provide such information in compliance with such obligations) in reasonable detail as it may have with respect to a Third Party Claim (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, invoice, billing or other document evidencing or asserting the same) to the other party if such other party is assuming defense of such Third Party Claim, and make available all records and other similar materials which are reasonably required in the defense of such Third Party Claim and shall otherwise reasonably cooperate with and assist the defending party in the defense of such Third Party Claim.

(g)    With respect to any Third Party Claim subject to indemnification under this ARTICLE X: (i) both the Indemnified Party and the Indemnifying Party, as the case may be, shall keep the other Person reasonably informed of the status of such Third Party Claims and any related judicial or other proceedings at all stages thereof where such Person is not represented by its own counsel and (ii) the parties agree (each at its own expense) to render to each other such assistance as they may reasonably require of each other and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any Third Party Claim.

All press releases or other public communications of any nature whatsoever relating to the transactions contemplated by this Agreement, and the method of the release for publication thereof, shall be subject to the prior consent of the Partnership and Proppants, which consent shall not be unreasonably withheld, conditioned or delayed by any Party; provided, however, that nothing herein shall prevent a Party from publishing such press releases or other public communications as such Party may consider necessary in order to satisfy such Party’s obligations at Law or under the rules of any stock or commodities exchange after consultation with the other Party as is reasonable under the circumstances.

Section 12.10    Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, then the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, then they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties to the greatest extent legally permissible.
