(a) The Parties intend that any Liability subject to indemnification, contribution or reimbursement pursuant to this Article IV will be net of Insurance Proceeds or other amounts actually recovered (net of any out-of-pocket costs or expenses incurred in the collection thereof) from any Person by or on behalf of the Indemnitee in respect of any indemnifiable Liability. Accordingly, the amount which either Party (an “ Indemnifying Party ”) is required to pay to any Person entitled to indemnification or contribution hereunder (an “ Indemnitee ”) will be reduced by any Insurance Proceeds or other amounts actually recovered (net of any out-of-pocket costs or expenses incurred in the collection thereof) from any Person by or on behalf of the Indemnitee in respect of the related Liability. If an Indemnitee receives a payment (an “ Indemnity Payment ”) required by this Agreement from an Indemnifying Party in respect of any Liability and subsequently receives Insurance Proceeds or any other amounts in respect of the related Liability, then the Indemnitee will pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or such other amounts (net of any out-of-pocket costs or expenses incurred in the collection thereof) had been received, realized or recovered before the Indemnity Payment was made.

-38-

(b) The Parties agree that an insurer that would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or, solely by virtue of any provision contained in this Agreement or any Ancillary Agreement, have any subrogation rights with respect thereto, it being understood that no insurer or any other Third Party shall be entitled to a “windfall” ( i.e. , a benefit they would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification and contribution provisions hereof. Each Party shall, and shall cause the members of its Group to, use commercially reasonable efforts (taking into account the probability of success on the merits and the cost of expending such efforts, including attorneys’ fees and expenses) to collect or recover any Insurance Proceeds that may be collectible or recoverable respecting the Liabilities for which indemnification or contribution may be available under this Article IV .

4.5 Procedures for Indemnification of Third-Party Claims .

(a) Notice of Claims. If, at or following the date of this Agreement, an Indemnitee shall receive notice or otherwise learn of the assertion by a Person (including any Governmental Authority) who is not a member of the Parent Group or the SpinCo Group of any claim or of the commencement by any such Person of any Action (collectively, a “ Third-Party Claim ”) with respect to which an Indemnifying Party may be obligated to provide indemnification to such Indemnitee pursuant to Section 4.2 or 4.3 , or any other Section of this Agreement or any Ancillary Agreement, such Indemnitee shall give such Indemnifying Party written notice thereof as soon as reasonably practicable, but in any event within 20 days (or sooner if the nature of the Third-Party Claim so requires) after becoming aware of such Third-Party Claim. Any such notice shall describe the Third-Party Claim in reasonable detail, including the facts and circumstances giving rise to such claim for indemnification, and include copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third-Party Claim. Notwithstanding the foregoing, the failure of an Indemnitee to provide notice in accordance with this Section 4.5(a) shall not relieve an Indemnifying Party of its indemnification obligations under this Agreement, except to the extent to which the Indemnifying Party is actually prejudiced by the Indemnitee’s failure to provide notice in accordance with this Section 4.5(a) .

(b) Control of Defense. An Indemnifying Party may elect to defend (and seek to settle or compromise), at its own expense and with its own counsel, any Third-Party Claim; provided , that, prior to the Indemnifying Party assuming and controlling defense of such Third-Party Claim, it shall first confirm to the Indemnitee in writing that, assuming the facts presented to the Indemnifying Party by the Indemnitee being true, the Indemnifying Party shall indemnify the Indemnitee for any such Damages to the extent resulting from, or arising out of, such Third-Party Claim. Notwithstanding the foregoing, if the Indemnifying Party assumes such defense and, in the course of defending such Third-Party Claim, (i) the Indemnifying Party discovers that the facts presented at the time the Indemnifying Party acknowledged its

-39-

indemnification obligation in respect of such Third-Party Claim were not true in all material respects and (ii) such untruth provides a reasonable basis for asserting that the Indemnifying Party does not have an indemnification obligation in respect of such Third-Party Claim, then (A) the Indemnifying Party shall not be bound by such acknowledgment, (B) the Indemnifying Party shall promptly thereafter provide the Indemnitee written notice of its assertion that it does not have an indemnification obligation in respect of such Third-Party Claim and (C) the Indemnitee shall have the right to assume the defense of such Third-Party Claim. Within thirty (30) days after the receipt of a notice from an Indemnitee in accordance with Section 4.5(a) (or sooner, if the nature of the Third-Party Claim so requires), the Indemnifying Party shall provide written notice to the Indemnitee indicating whether the Indemnifying Party shall assume responsibility for defending the Third-Party Claim. If an Indemnifying Party elects not to assume responsibility for defending any Third-Party Claim or fails to notify an Indemnitee of its election within thirty (30) days after receipt of the no tice from an Indemnitee as provided in Section 4.5(a) , then the Indemnitee that is the subject of such Third-Party Claim shall be entitled to continue to conduct and control the defense of such Third-Party Claim.

(c) Allocation of Defense Costs . If an Indemnifying Party has elected to assume the defense of a Third-Party Claim, then such Indemnifying Party shall be solely liable for all fees and expenses incurred by it in connection with the defense of such Third-Party Claim and shall not be entitled to seek any indemnification or reimbursement from the Indemnitee for any such fees or expenses incurred by the Indemnifying Party during the course of the defense of such Third-Party Claim by such Indemnifying Party, regardless of any subsequent decision by the Indemnifying Party to reject or otherwise abandon its assumption of such defense. If an Indemnifying Party elects not to assume responsibility for defending any Third-Party Claim or fails to notify an Indemnitee of its election within thirty (30) days after receipt of a notice from an Indemnitee as provided in Section 4.5(a) , and the Indemnitee conducts and controls the defense of such Third-Party Claim and the Indemnifying Party has an indemnification obligation with respect to such Third-Party Claim, then the Indemnifying Party shall be liable for all reasonable fees and expenses incurred by the Indemnitee in connection with the defense of such Third-Party Claim.

(d) Right to Monitor and Participate. An Indemnitee that does not conduct and control the defense of any Third-Party Claim, or an Indemnifying Party that has failed to elect to defend any Third-Party Claim as contemplated hereby, nevertheless shall have the right to employ separate counsel (including local counsel as necessary) of its own choosing to monitor and participate in (but not control) the defense of any Third-Party Claim for which it is a potential Indemnitee or Indemnifying Party, but the fees and expenses of such counsel shall be at the expense of such Indemnitee or Indemnifying Party, as the case may be, and the provisions of Section 4.5(c) shall not apply to such fees and expenses. Notwithstanding the foregoing, but subject to Sections 6.7 and 6.8 , such Party shall cooperate with the Party entitled to conduct and control the defense of such Third-Party Claim in such defense and make available to the controlling Party, at the non-controlling Party’s expense, all witnesses, information and materials in such Party’s possession or under such Party’s control relating thereto as are reasonably

-40-

required by the controlling Party. In addition to the foregoing, if any Indemnitee shall in good faith determine that such Indemnitee and the Indemnifying Party have actual or potential differing defenses or conflicts of interest between them that make joint representation inappropriate, then the Indemnitee shall have the right to employ separate counsel (including local counsel as necessary) and to participate in (but not control) the defense, compromise, or settlement thereof, and the Indemnifying Party shall bear the reasonable fees and expenses of such counsel for all Indemnitees.

(e) No Settlement. No Party may settle or compromise any Third-Party Claim for which a Party is seeking to be indemnified hereunder without the prior written consent of the other Parties, which consent may not be unreasonably withheld, unless such settlement or compromise is solely for monetary damages, does not involve any finding or determination of wrongdoing or violation of Law by the other Parties and provides for a full, unconditional and irrevocable release of the other Parties from all Liability in connection with the Third-Party Claim.

4.6 Additional Matters .

(a) Timing of Payments. Indemnification or contribution payments in respect of any Liabilities for which an Indemnitee is entitled to indemnification or contribution under this Article IV shall be paid reasonably promptly (but in any event within forty-five (45) days of the final determination of the amount that the Indemnitee is entitled to indemnification or contribution under this Article IV ) by the Indemnifying Party to the Indemnitee as such Liabilities are incurred upon demand by the Indemnitee, including reasonably satisfactory documentation setting forth the basis for the amount of such indemnification or contribution payment, including documentation with respect to calculations made and consideration of any Insurance Proceeds that actually reduce the amount of such Liabilities. The indemnity and contribution provisions contained in this Article IV shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Indemnitee, and (ii) the knowledge by the Indemnitee of Liabilities for which it might be entitled to indemnification hereunder.

(b) Notice of Direct Claims. Any claim for indemnification or contribution under this Agreement or any Ancillary Agreement that does not result from a Third-Party Claim shall be asserted by written notice given by the Indemnitee to the applicable Indemnifying Party; provided , that the failure by an Indemnitee to so assert any such claim shall not prejudice the ability of the Indemnitee to do so at a later time except to the extent (if any) that the Indemnifying Party is prejudiced thereby. Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such thirty (30)-day period or rejects such claim in whole or in part, such Indemnitee shall, subject to the provisions of Article VII , be free to pursue such remedies as may be available to such party as contemplated by this Agreement and the Ancillary Agreements, as applicable, without prejudice to its continuing rights to pursue indemnification or contribution hereunder.

-41-

(c) Pursuit of Claims Against Third Parties. If (i) a Party incurs any Liability arising out of this Agreement or any Ancillary Agreement; (ii) an adequate legal or equitable remedy is not available for any reason against the other Party to satisfy the Liability incurred by the incurring Party; and (iii) a legal or equitable remedy may be available to the other Party against a Third Party for such Liability, then the other Party shall use its commercially reasonable efforts to cooperate with the incurring Party, at the incurring Party’s expense, to permit the incurring Party to obtain the benefits of such legal or equitable remedy against the Third Party.

(d) Subrogation. In the event of payment by or on behalf of any Indemnifying Party to any Indemnitee in connection with any Third-Party Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third-Party Claim against any claimant or plaintiff asserting such Third-Party Claim or against any other Person. Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

(e) Substitution. In the event of an Action in which the Indemnifying Party is not a named defendant, if either the Indemnitee or Indemnifying Party shall so request, the Parties shall endeavor to substitute the Indemnifying Party for the named defendant. If such substitution or addition cannot be achieved for any reason or is not requested, the named defendant shall allow the Indemnifying Party to manage the Action as set forth in Section 4.5 and this Section 4.6 , and the Indemnifying Party shall fully indemnify the named defendant against all costs of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees, experts fees and all other external expenses), the costs of any judgment or settlement and the cost of any interest or penalties relating to any judgment or settlement.

4.7 Right of Contribution .

(a) Contribution. If any right of indemnification contained in Section 4.2 or Section 4.3 is held unenforceable or is unavailable for any reason, or is insufficient to hold harmless an Indemnitee in respect of any Liability for which such Indemnitee is entitled to indemnification hereunder, then the Indemnifying Party shall contribute to the amounts paid or payable by the Indemnitees as a result of such Liability (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and the members of its Group, on the one hand, and the Indemnitees entitled to contribution, on the other hand, as well as any other relevant equitable considerations.

(b) Allocation of Relative Fault. Solely for purposes of determining relative fault pursuant to this Section 4.7 : (i) any fault associated with the business conducted with the Delayed Transferred Assets or Delayed Assumed Liabilities (except for the gross negligence or intentional misconduct of a member of the Parent Group) or with the ownership, operation or activities of the Transferred Business prior to the

-42-

Effective Time shall be deemed to be the fault of SpinCo and the other members of the SpinCo Group, and no such fault shall be deemed to be the fault of Parent or any other member of the Parent Group; (ii) any fault associated with the business conducted with Delayed Retained Assets or Delayed Retained Liabilities (except for the gross negligence or intentional misconduct of a member of the SpinCo Group) shall be deemed to be the fault of Parent and the other members of the Parent Group, and no such fault shall be deemed to be the fault of SpinCo or any other member of the SpinCo Group; and (iii) any fault associated with the ownership, operation or activities of the Retained Business prior to the Effective Time shall be deemed to be the fault of Parent and the other members of the Parent Group, and no such fault shall be deemed to be the fault of SpinCo or any other member of the SpinCo Group.

4.8 Covenant Not to Sue . Each Party hereby covenants and agrees that none of it, the members of such Party’s Group or any Person claiming through it shall bring suit or otherwise assert any claim against any Indemnitee, or assert a defense against any claim asserted by any Indemnitee, before any court, arbitrator, mediator or administrative agency anywhere in the world, alleging that: (a) the assumption of any Assumed Liabilities by SpinCo or a member of the SpinCo Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason; (b) the retention of any Retained Liabilities by Parent or a member of the Parent Group on the terms and conditions set forth in this Agreement and the Ancillary Agreements is void or unenforceable for any reason; or (c) the provisions of this Article IV are void or unenforceable for any reason.

4.9 Remedies Cumulative . The remedies provided in this Article IV shall be cumulative and, subject to the provisions of Article VIII , shall not preclude assertion by any Indemnitee of any other rights or the seeking of any and all other remedies against any Indemnifying Party.

Parent shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any Privileged Information that relates solely to any Retained Liabilities resulting from any Actions that are now pending or may be asserted in the future, whether or not the Privileged Information is in the possession or under the control of any member of the Parent Group or any member of the SpinCo Group; and

(ii) SpinCo shall be entitled, in perpetuity, to control the assertion or waiver of all privileges and immunities in connection with any Privileged Information that relates solely to the Transferred Business and not to the Retained Business, whether or not the Privileged Information is in the possession or under the control of any member of the SpinCo Group or any member of the Parent Group.

If any confidential and proprietary information of one Party or any member of its Group is disclosed to the other Party or any member of such other Party’s Group in connection with providing services to such first Party or any member of such first Party’s Group under this Agreement, the Merger Agreement or any Ancillary Agreement, then such disclosed confidential and proprietary information shall be used only as required to perform such services.

In the event that a Party or any member of its Group either determines on the advice of its counsel that it is required to disclose any information pursuant to applicable Law or receives any request or demand under lawful process or from any Governmental Authority to disclose or provide information of the other Party (or any member of the other Party’s Group) that is subject to the confidentiality provisions hereof, such Party shall notify the other Party (to the extent legally permitted) as promptly as practicable under the circumstances prior to disclosing or providing such information and shall cooperate, at the expense of the other Party, in seeking any appropriate protective order requested by the other Party. In the event that such other Party fails to receive such appropriate protective order in a timely manner and the Party receiving the request or demand reasonably determines that its failure to disclose or provide such information shall actually prejudice the Party receiving the request or demand, then the Party that received such request or demand may thereafter disclose or provide information to the extent required by such Law (as so advised by its counsel) or by lawful process or such Governmental Authority, and the disclosing Party shall promptly provide the other Party with a copy of the information so disclosed, in the same form and format so disclosed, together with a list of all Persons to whom such information was disclosed, in each case to the extent legally permitted.

ARTICLE VII

DISPUTE RESOLUTION

7.1 Good-Faith Negotiation . Subject to Section 7.4 , either Party seeking resolution of any dispute, controversy or claim arising out of or relating to this Agreement or Ancillary Agreement (including regarding whether any Assets are Transferred Assets, any Assets are Retained Assets, any Liabilities are Assumed Liabilities, any Liabilities are Retained Liabilities or the validity, interpretation, breach or termination of this Agreement or any Ancillary Agreement) (a “ Dispute ”), shall provide written notice thereof to the other Party (the “ Initial Notice ”), and within thirty (30) days of the delivery of the Initial Notice, the Parties shall attempt in good faith to negotiate a resolution of the Dispute. The negotiations shall be conducted by executives who hold, at a minimum, the title of senior vice president and who have authority to settle the Dispute. All such negotiations shall be confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence. If the

-50-

Parties are unable for any reason to resolve a Dispute within thirty (30) days after the delivery of such notice or if a Party reasonably concludes that the other Party is not willing to negotiate as contemplated by this Section 7.1 , the Dispute shall be submitted to mediation in accordance with Section 7.2 .

7.2 Mediation . Any Dispute not resolved pursuant to Section 7.1 shall, at the written request of a Party (a “ Mediation Request ”), be submitted to nonbinding mediation in accordance with the then current International Institute for Conflict Prevention and Resolution Mediation Procedure (the “ CPR Mediation Procedure ”), except as modified herein. The mediation shall be held in Pittsburgh, Pennsylvania or such other place as the Parties may mutually agree in writing. The Parties shall have twenty (20) days from receipt by a Party of a Mediation Request to agree on a mediator. If no mediator has been agreed upon by the Parties within twenty (20) days of receipt by a party of a Mediation Request, then a Party may request (on written notice to the other Party), that CPR appoint a mediator in accordance with the CPR Mediation Procedure. All mediation pursuant to this clause shall be confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence, and no oral or documentary representations made by the Parties during such mediation shall be admissible for any purpose in any subsequent proceedings. No Party shall disclose or permit the disclosure of any information about the evidence adduced or the documents produced by the other Party in the mediation proceedings or about the existence, contents or results of the mediation without the prior written consent of such other Party, except in the course of a judicial or regulatory proceeding or as may be required by Law or requested by a Governmental Authority or securities exchange. Before making any disclosure permitted by the preceding sentence, the Party intending to make such disclosure shall, to the extent reasonably practicable, give the other Party reasonable written notice of the intended disclosure and afford the other Party a reasonable opportunity to protect its interests. If the Dispute has not been resolved within sixty (60) days of the appointment of a mediator, or within ninety (90) days after receipt by a Party of a Mediation Request (whichever occurs sooner), or within such longer period as the Parties may agree to in writing, then the Dispute shall be submitted to binding arbitration in accordance with Section 7.3 .

7.3 Arbitration .

(a) In the event that a Dispute has not been resolved within sixty (60) days of the appointment of a mediator in accordance with Section 7.2 , or within ninety (90) days after receipt by a Party of a Mediation Request (whichever occurs sooner), or within such longer period as the Parties may agree to in writing, then such Dispute shall, upon the written request of a Party (the “ Arbitration Request ”) be submitted to be finally resolved by binding arbitration pursuant to the then current International Institute for Conflict Prevention and Resolution Arbitration Procedure (“ CPR Arbitration Procedure ”). The arbitration shall be held in the same location as the mediation pursuant to Section 7.2 . Unless otherwise agreed by the Parties in writing, any Dispute to be decided pursuant to this Section 7.3 will be decided (i) before a sole arbitrator if the amount in dispute, inclusive of all claims and counterclaims, totals less than $2 million; or (ii) by a panel of three (3) arbitrators if the amount in dispute, inclusive of all claims and counterclaims, totals $2 million or more.

-51-

(b) The panel of three (3) arbitrators will be chosen as follows: (i) within fifteen (15) days from the date of the receipt of the Arbitration Request, each Party will name an arbitrator; and (ii) the two (2) Party-appointed arbitrators will thereafter, within thirty (30) days from the date on which the second of the two (2) arbitrators was named, name a third, independent arbitrator who will act as chairperson of the arbitral tribunal. In the event that either Party fails to name an arbitrator within fifteen (15) days from the date of receipt of the Arbitration Request, then upon written application by either Party, that arbitrator shall be appointed pursuant to the CPR Arbitration Procedure. In the event that the two (2) Party-appointed arbitrators fail to appoint the third, then the third, independent arbitrator will be appointed pursuant to the CPR Arbitration Procedure. If the arbitration will be before a sole independent arbitrator, then the sole independent arbitrator will be appointed by agreement of the Parties within fifteen (15) days of the date of receipt of the Arbitration Request. If the Parties cannot agree to a sole independent arbitrator, then upon written application by either Party, the sole independent arbitrator will be appointed pursuant to the CPR Arbitration Procedure.

(c) The arbitrator(s) will have the right to award, on an interim basis, or include in the final award, any relief which it deems proper in the circumstances, including money damages (with interest on unpaid amounts from the due date), injunctive relief (including specific performance) and attorneys’ fees and costs; provided , that the arbitrator(s) will not award any relief not specifically requested by the parties and, in any event, will not award any indirect, punitive, exemplary, remote, speculative or similar damages in excess of compensatory damages of the other arising in connection with the transactions contemplated hereby (other than any such Liability with respect to a Third-Party Claim). Upon selection of the arbitrator(s) following any grant of interim relief by a special arbitrator or court pursuant to Section 7.4 , the arbitrator(s) may affirm or disaffirm that relief, and the parties will seek modification or rescission of the order entered by the court as necessary to accord with the decision of the arbitrator(s). The award of the arbitrator(s) shall be final and binding on the Parties, and may be enforced in any court of competent jurisdiction. The initiation of mediation or arbitration pursuant to this Article VII will toll the applicable statute of limitations for the duration of any such proceedings.

7.4 Litigation and Unilateral Commencement of Arbitration . Notwithstanding the foregoing provisions of this Article VII , (a) a Party may seek preliminary provisional or injunctive judicial relief with respect to a Dispute without first complying with the procedures set forth in Section 7.1 , Section 7.2 and Section 7.3 if such Action is reasonably necessary to avoid irreparable damage and (b) either Party may initiate arbitration before the expiration of the periods specified in Section 7.2 and Section 7.3 if (i) such Party has submitted a Mediation Request or Arbitration Request, as applicable, and the other party has failed, within the applicable periods set forth in Section 7.3 to agree upon a date for the first mediation session to take place within thirty (30) days after the appointment of such mediator or such longer period as the Parties may agree to in writing or (ii) such Party has failed to comply with Section 7.3 in good faith with respect to commencement and engagement in arbitration. In such event, the other Party may commence and prosecute such arbitration unilaterally in accordance with the CPR Arbitration Procedure.

-52-

7.5 Conduct During Dispute Resolution Process . Unless otherwise agreed in writing, the Parties shall, and shall cause their respective members of their Group to, continue to honor all commitments under this Agreement, the Merger Agreement and each Ancillary Agreement to the extent required by such agreements during the course of dispute resolution pursuant to the provisions of this Article VII , unless such commitments are the specific subject of the Dispute at issue.
