TRANSITION SERVICES AGREEMENT

This TRANSITION SERVICES AGREEMENT (together with the Schedules hereto, this “Agreement”) is entered into as of June 8, 2015, by and between Babcock & Wilcox Enterprises, Inc., a Delaware corporation (“SpinCo”) and The Babcock & Wilcox Company, a Delaware corporation (“RemainCo”).

WHEREAS, the Board of Directors of RemainCo has determined that it would be appropriate and desirable for RemainCo to distribute (the “Distribution”) on a pro rata basis to the holders of outstanding shares of common stock, par value $0.01 per share, of RemainCo all of the outstanding shares of common stock, par value $0.01 per share, of SpinCo owned by RemainCo;

WHEREAS, in order to effectuate the foregoing, RemainCo and SpinCo have entered into a Master Separation Agreement, dated as of the date hereof (the “Master Separation Agreement”), which provides, among other things, upon the terms and subject to the conditions thereof, for the separation of the respective businesses of RemainCo and SpinCo and the Distribution, and the execution and delivery of certain other agreements, including this Agreement, in order to facilitate and provide for the foregoing; and

WHEREAS, in order to provide for an orderly transition under the Master Separation Agreement, it will be advisable for SpinCo, through members of the SpinCo Group, to provide to RemainCo certain services described herein for a transitional period.

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows:

Section 2.1 Services.

(a) Upon the terms and subject to the conditions of this Agreement, SpinCo, acting directly and/or through its Affiliates and their respective employees, agents, contractors or independent third parties designated by any of them, agrees to use commercially reasonable efforts to provide or to cause to be provided services to the RemainCo Group as set forth in Schedules A through E (including any Additional Services provided in accordance with Section 2.3 hereof, all such services are collectively referred to herein as the “Services”).

(b) At all times during the performance of the Services, all Persons performing such Services (including agents, temporary employees, independent third parties and consultants) shall be construed as being independent from the RemainCo Group, and such Persons shall not be considered or deemed to be employees of any member of the RemainCo Group nor entitled to any employee benefits of RemainCo as a result of this Agreement. The responsibility of such Persons is to perform the Services in accordance with this Agreement and, as necessary, to advise the applicable member of the RemainCo Group in connection therewith, and such Persons shall not be responsible for decision-making on behalf of any member of the RemainCo Group. Such Persons shall not be required to report to management of any member of the RemainCo Group nor be deemed to be under the management or direction of any member of the RemainCo Group. RemainCo acknowledges and agrees that, except as may be expressly set forth herein as a Service (including any Additional Services provided in accordance with Section 2.3 hereof) or otherwise expressly set forth in the Master Separation Agreement or an Ancillary Agreement, no member of the SpinCo Group shall be obligated to provide, or cause to be provided, any service or goods to any member of the RemainCo Group.

(c) Notwithstanding anything to the contrary in this Agreement, SpinCo and members of the SpinCo Group shall not be required to perform Services hereunder or take any actions relating thereto that conflict with or violate any applicable Law, contract, license, authorization, certification or permit or SpinCo’s Code of Business Conduct or other governance policies, as they may be amended from time to time.

- 2 -

Section 2.2 Service Coordinators. Each party will nominate in writing a representative to act as the primary contact with respect to the provision of the Services and the resolution of disputes under this Agreement (each such person, a “Service Coordinator”). The initial Service Coordinators shall be David S. Black (for RemainCo) and Jude T. Broussard (for SpinCo) (or their designated delegates) for each of RemainCo and SpinCo, respectively. The Service Coordinators shall meet as expeditiously as possible to resolve any dispute hereunder; and any dispute that is not resolved by the Service Coordinators within 45 days shall be resolved in accordance with the dispute resolution procedures set forth in Article V of the Master Separation Agreement. Each party hereto may treat an act of a Service Coordinator of the other party hereto which is consistent with the provisions of this Agreement as being authorized by such other party without inquiring behind such act or ascertaining whether such Service Coordinator had authority to so act; provided, however, that no such Service Coordinator shall have authority to amend this Agreement. RemainCo and SpinCo shall advise each other promptly (in any case no more than three Business Days) in writing of any change in their respective Service Coordinators, setting forth the name of the replacement, and stating that the replacement Service Coordinator is authorized to act for such party in accordance with this Section 2.2.

Section 2.3 Additional Services. RemainCo may request additional Services (the “Additional Services”) from SpinCo by providing written notice. Upon the mutual written agreement as to the nature, cost, duration and scope of such Additional Services, RemainCo and SpinCo shall supplement in writing the Schedules hereto to include such Additional Services. Subject to the other limitations in this Agreement, including the provisions in Section 2.6, but notwithstanding the foregoing provisions of this Section 2.3, in addition to providing the Services specified in the Schedules, SpinCo, acting directly and/or through its Affiliates and their respective employees, agents, contractors or independent third parties designated by any of them, shall use commercially reasonable efforts to provide or to cause to be provided additional, de minimis administrative support services to the RemainCo Group as may be requested by any member of the RemainCo Group from time to time, at no cost beyond the amounts set forth in the Schedules (as the amounts set forth in the Schedules contemplate such additional, de minimis administrative support services); provided, however, that, for any such additional services to be considered de minimis for purposes of this sentence, such additional services shall not require the attention of (i) any one employee of any member of the SpinCo Group for more than 2 hours in any single calendar month or (ii) any group of employees of any one or more members of the SpinCo Group for more than 30 hours in any single calendar month. Except where the context otherwise indicates or requires, any such additional services referred to in the immediately preceding sentence shall be deemed to be “Services” under this Agreement.

Section 2.4 Third Party Services. SpinCo shall have the right to hire third-party subcontractors to provide all or part of any Service hereunder except as specifically prohibited by the Schedule defining such Service; provided, that SpinCo shall consult in good faith with

- 3 -

RemainCo regarding the proposed hiring of any third-party subcontractor that has not previously been involved in the activities relating to such Service prior to the date hereof; provided, further, that, in the event such subcontracting is inconsistent with the practice applied by SpinCo generally from time to time within its own organization, SpinCo shall give notice to RemainCo of its intent to subcontract any portion of the Services and RemainCo shall have 20 days (or such lesser period set forth in the notice as may be practicable in the event of exigent circumstances) to determine, in its sole discretion, whether to permit such subcontracting or whether to cancel such Service in accordance with Article VI hereof. If RemainCo opts to cancel a Service pursuant to the immediately preceding sentence, it shall not be liable to SpinCo pursuant to Section 6.1 for any costs or expenses SpinCo or any member of the SpinCo Group remains obligated to pay to the third-party subcontractor identified in the notice provided by SpinCo as described above. SpinCo shall not be required to give notice of its intent to subcontract Services to any party listed on Exhibit 2.4 hereto, nor shall RemainCo have any right to cancel any Service subcontracted to any such listed party pursuant to this Section 2.4 (provided, that this sentence shall not prevent RemainCo from cancelling any Service pursuant to Section 6.1).

Section 2.5 Standard of Performance; Limitation of Liability.

(a) The Services to be provided hereunder shall be performed with the same general degree of care, at the same general level and at the same general degree of accuracy and responsiveness, as when performed within the RemainCo organization (including, for this purpose, SpinCo and the SpinCo Group) prior to the date of this Agreement. It is understood and agreed that SpinCo and the members of the SpinCo Group are not professional providers of the types of services included in the Services and that SpinCo personnel performing Services have other responsibilities and will not be dedicated full-time to performing Services hereunder.

(b) In the event SpinCo or any member of the SpinCo Group fails to provide, or cause to be provided, the Services in accordance with the standard of service set forth in Section 2.5(a), the sole and exclusive remedy of RemainCo shall be, at RemainCo’s sole discretion, within 90 days from the date that SpinCo or such member of the SpinCo Group first fails to provide such Service, to not pay for such Service; provided that in the event SpinCo defaults in the manner described in clause (ii) of Section 7.1, RemainCo shall have the further rights set forth in Article VII.

(c) EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 2.5, NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, EXPRESSED OR IMPLIED (INCLUDING THE WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR CONFORMITY TO ANY REPRESENTATION OR DESCRIPTION), ARE MADE BY SPINCO OR ANY MEMBER OF THE SPINCO GROUP WITH RESPECT TO THE SERVICES UNDER THIS AGREEMENT AND, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL SUCH REPRESENTATIONS OR WARRANTIES ARE HEREBY WAIVED AND DISCLAIMED. REMAINCO (ON ITS OWN BEHALF AND ON BEHALF OF EACH OTHER MEMBER OF THE REMAINCO GROUP) HEREBY EXPRESSLY WAIVES ANY RIGHT REMAINCO OR ANY MEMBER OF THE REMAINCO GROUP MAY OTHERWISE HAVE FOR ANY LOSSES, TO ENFORCE SPECIFIC PERFORMANCE OR TO PURSUE ANY OTHER REMEDY AVAILABLE IN CONTRACT, AT LAW OR IN EQUITY IN THE EVENT OF

- 4 -

ANY NON-PERFORMANCE, INADEQUATE PERFORMANCE, FAULTY PERFORMANCE OR OTHER FAILURE OR BREACH BY SPINCO OR ANY MEMBER OF THE SPINCO GROUP UNDER OR RELATING TO THIS AGREEMENT, NOTWITHSTANDING THE NEGLIGENCE OR GROSS NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT OR ACTIVE OR PASSIVE) OF SPINCO OR ANY MEMBER OF THE SPINCO GROUP OR ANY THIRD PARTY SERVICE PROVIDER AND WHETHER DAMAGES ARE ASSERTED IN CONTRACT OR TORT, UNDER FEDERAL, STATE OR NON U.S. LAWS OR OTHER STATUTE OR OTHERWISE; PROVIDED, HOWEVER, THAT THE FOREGOING WAIVER SHALL NOT EXTEND TO COVER, AND SPINCO SHALL BE RESPONSIBLE FOR, SUCH LOSSES CAUSED BY THE WILLFUL MISCONDUCT OF SPINCO OR ANY MEMBER OF THE SPINCO GROUP. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IN NO EVENT SHALL THE SPINCO GROUP BE LIABLE TO THE REMAINCO GROUP WITH RESPECT TO CLAIMS ARISING OUT OF THIS AGREEMENT FOR AMOUNTS IN THE AGGREGATE EXCEEDING THE AGGREGATE SERVICE CHARGES PAID HEREUNDER BY THE REMAINCO GROUP.

Section 2.6 Service Boundaries and Scope. Except as provided in a Schedule for a specific Service, the Services shall be available only for purposes of conducting the business of the RemainCo Group substantially in the manner it was conducted immediately prior to the Distribution Date. Except as provided in a Schedule for a specific Service, in providing, or causing to be provided, the Services, SpinCo shall not be obligated to: (i) maintain the employment of any specific employee or hire additional employees or third-party service providers; (ii) purchase, lease or license any additional equipment (including computer equipment, furniture, furnishings, fixtures, machinery, vehicles, tools and other tangible personal property), software or other assets, rights or properties; (iii) make modifications to its existing systems or software; (iv) provide any member of the RemainCo Group with access to any systems or software other than those to which it has authorized access immediately prior to the Distribution Date; or (v) pay any costs related to the transfer or conversion of data of any member of the RemainCo Group. RemainCo acknowledges (on its own behalf and on behalf of the other members of the RemainCo Group) that the employees of SpinCo or any other members of the SpinCo Group who may be assisting in the provision of Services hereunder are at-will employees and, as such, may terminate or be terminated from employment with SpinCo or any of the other members of the SpinCo Group providing Services hereunder at any time for any reason. In no event shall SpinCo or any of its Affiliates or any of their respective employees or agents be required to perform any Services or take any other actions hereunder that conflict with any applicable Law. For the avoidance of doubt and except as may hereafter be designated as Additional Services in accordance with Section 2.3, the Services do not include any services required for or as the result of any business acquisitions, divestitures, start-ups or, shutdowns or discontinuation of current business lines by the RemainCo Group. To the extent RemainCo desires SpinCo to provide any services in connection with any such acquisitions, divestitures, start-ups or, shutdowns or discontinuation of current business lines, RemainCo shall follow the procedures for requesting Additional Services pursuant to Section 2.3.

Section 2.7 Cooperation. RemainCo and SpinCo shall cooperate with one another and provide such further assistance as the other party may reasonably request in connection with (a) the provision of Services hereunder or (b) the compliance with any Laws imposed on either SpinCo or RemainCo.

- 5 -

Section 2.8 Transitional Nature of Services; Changes. Subject to Sections 2.3 and 2.5, the parties acknowledge the transitional nature of the Services and that SpinCo may make changes from time to time in the manner of performing the Services.

Section 2.9 Access. During the term of this Agreement and for so long as any Services are being provided to RemainCo by SpinCo, RemainCo will provide SpinCo and its authorized representatives reasonable access, during regular business hours upon reasonable notice, to RemainCo and its employees, representatives, facilities and books and records as SpinCo and its representatives may reasonably require in order to perform such Services.

ARTICLE III

SERVICE CHARGES

Section 3.1 Compensation. Subject to the specific terms of this Agreement, the compensation to be received by SpinCo for each Service provided hereunder will be the fees set forth on the Schedule relating to the particular Service, subject to any escalation provided for on such Schedule. In consideration for the provision of a Service, each member of the RemainCo Group receiving such Service shall pay to SpinCo or, at the election of SpinCo, the member of the SpinCo Group providing such Service, the applicable fee for such Service as set forth on the attached Schedules.

ARTICLE IV

PAYMENT

Section 4.1 Payment. Except as otherwise provided in a Schedule for a specific Service, charges for Services shall be invoiced monthly in arrears based on the Services provided by SpinCo or, at its option, the member of the SpinCo Group providing the Service. Except as otherwise provided in a Schedule for a specific Service, RemainCo shall make the corresponding payment no later than 60 days after receipt of the invoice. Unless otherwise provided in this Agreement, RemainCo shall remit funds in payment of invoices provided hereunder either by wire transfer or ACH (Automated Clearing House) in accordance with the payment instructions set forth in Schedule 4.1. Each invoice shall be directed to the RemainCo Service Coordinator or such other person designated in writing from time to time by such Service Coordinator. The invoice shall set forth in reasonable detail the Services rendered and the invoice amount for the Services rendered for the period covered by such invoice. Interest will accrue on any unpaid amounts at ten percent (10%) per annum (compounded monthly) or, if less, the maximum non-usurious rate of interest permitted by applicable law, until such amounts, together with all accrued and unpaid interest thereon, are paid in full. All timely payments under this Agreement shall be made without early payment discount. Any preexisting obligation to make payment for Services provided hereunder shall survive the termination of this Agreement. If SpinCo incurs any reasonable out-of-pocket expenses (including any incremental license fees incurred by SpinCo in connection with performance of the Services and any travel expenses incurred at the

- 6 -

request or with the consent of RemainCo) or remits funds to a third-party on behalf of RemainCo, in either case in connection with the rendering of Services, then SpinCo shall include such amount on its monthly invoice to RemainCo, with reasonable supporting documentation, and RemainCo shall reimburse that amount to SpinCo pursuant to this Section 4.1 as part of its next monthly payment.

Section 4.2 Payment Disputes. RemainCo may object to any amounts for any Service at any time before, at the time of, or after payment is made, provided such objection is made in writing to SpinCo within 90 days following the date of the disputed invoice. RemainCo shall timely pay the disputed items in full while resolution of the dispute is pending; provided, however, that SpinCo shall pay interest at a rate of five percent (5%) per annum (compounded monthly) on any amounts it is required to return to RemainCo upon resolution of the dispute. Payment of any amount shall not constitute approval thereof. The Service Coordinators shall meet as expeditiously as possible to resolve any dispute. Any dispute that is not resolved by the Service Coordinators within 45 days shall be resolved in accordance with the dispute resolution and arbitration procedures set forth in Article V of the Master Separation Agreement. Neither party (or any member of its respective Group) shall have a right of set-off against the other party (or any member of its respective Group) for billed amounts hereunder. Upon written request, SpinCo will provide to RemainCo reasonable detail and support documentation to permit RemainCo to verify the accuracy of an invoice.

Section 4.3 Review of Charges; Error Correction. SpinCo shall maintain accurate books and records (including invoices of third parties) related to the Services sufficient to calculate, and allow RemainCo to verify, the amounts owed under this Agreement. From time to time until 120 days following the termination of this Agreement, RemainCo shall have the right to review, and SpinCo shall provide access to, such books and records to verify the accuracy of such amounts, provided that such reviews shall not occur more frequently than once per calendar quarter. Each such review shall be conducted during normal business hours and in a manner that does not unreasonably interfere with the operations of SpinCo. If, as a result of any such review, RemainCo determines that it overpaid any amount to SpinCo, then RemainCo may raise an objection pursuant to the provisions of Section 4.2. RemainCo shall bear the cost and expense of any such review. SpinCo shall make adjustments to charges as required to reflect the discovery of errors or omissions in charges.

Section 4.4 Taxes. All transfer taxes, excises, fees or other charges (including value added, sales, use or receipts taxes, but not including a tax on or measured by the income, net or gross revenues, business activity or capital of a member of the SpinCo Group), or any increase therein, now or hereafter imposed directly or indirectly by law upon any fees paid hereunder for Services, which a member of the SpinCo Group is required to pay or incur in connection with the provision of Services hereunder (“Tax”), shall be passed on to RemainCo as an explicit surcharge and shall be paid by RemainCo in addition to any Service fee payment, whether included in the applicable Service fee payment, or added retroactively. If RemainCo submits to SpinCo a timely and valid resale or other exemption certificate acceptable to SpinCo and sufficient to support the exemption from Tax, then such Tax will not be added to the Service fee payable pursuant to Article III; provided, however, that if a member of the SpinCo Group is ever required to pay such Tax, RemainCo will promptly reimburse SpinCo for such Tax, including any interest, penalties and attorney’s fees related thereto. The parties will cooperate to minimize the imposition of any Taxes.

- 7 -

Section 4.5 Records. SpinCo shall maintain true and correct records of all receipts, invoices, reports and such other documents relating to the Services hereunder in accordance with its standard accounting practices and procedures, consistently applied. SpinCo shall retain such accounting records and make them available to RemainCo’s authorized representatives and auditors for a period of not less than one year from the close of each fiscal year of SpinCo; provided, however, that SpinCo may, at its option, transfer such accounting records to RemainCo upon termination of this Agreement.

ARTICLE V

TERM

Section 5.1 Term. Subject to Articles VI and VII, the SpinCo Group shall provide the specific Services to the RemainCo Group pursuant to this Agreement for the time period set forth on the Schedule relating to the specific Service. In accordance with the Master Separation Agreement and Article VI of this Agreement, except as otherwise provided in a Schedule for a specific Service, RemainCo shall undertake to provide to itself and members of the RemainCo Group, and to terminate as soon as reasonably practicable, the Services provided to the RemainCo Group hereunder. Except as otherwise provided in a Schedule for a specific Service or group of related Services, all Services provided for hereunder shall terminate on December 31, 2016. Except as otherwise expressly agreed or unless sooner terminated, this Agreement shall commence upon the Distribution Date and shall continue in full force and effect between the parties for so long as any Service set forth in any Schedule hereto is being provided to RemainCo or members of the RemainCo Group and this Agreement shall terminate upon the cessation of all Services provided hereunder; provided that Articles I, IV, VIII, IX and XI and Sections 2.5(c) and 2.7 will survive the termination of this Agreement and any such termination shall not affect any obligation for the payment of Services rendered prior to termination.

ARTICLE VI

DISCONTINUATION OF SERVICES

Section 6.1 Discontinuation of Services. Unless otherwise provided in the relevant Schedule for a particular Service, at any time after the Distribution Date, RemainCo may, without cause and in accordance with the terms and conditions hereunder and the Master Separation Agreement, request the discontinuation of one or more specific Services by giving SpinCo at least 30 days’ prior written notice; provided, however, that any such discontinuation will not affect the amounts payable to SpinCo hereunder unless (and then only to the extent that) the charges for the discontinued Services have been separately identified in the applicable Schedule. RemainCo shall be liable to SpinCo for all costs and expenses SpinCo or any member of the SpinCo Group remains obligated to pay in connection with any discontinued Service or Services, except in the case of a Service terminated by RemainCo pursuant to clause (ii) of the first sentence of Section 7.1 hereof. The parties shall cooperate as reasonably required to effectuate an orderly and systematic transfer to the RemainCo Group of all of the duties and obligations previously performed by SpinCo or a member of the SpinCo Group under this Agreement.

- 8 -

Section 6.2 Procedures Upon Discontinuation or Termination of Services. Upon the discontinuation or termination of a Service hereunder, this Agreement shall be of no further force and effect with respect to such Service, except as otherwise provided in a Schedule for a specific Service and except as to obligations accrued prior to the date of discontinuation or termination; provided, however, that Articles I, IV, VIII, IX and XI and Section 2.5(c) of this Agreement shall survive such discontinuation or termination. Each party and the applicable member(s) of its respective Group shall, within 60 days after discontinuation or termination of a Service, deliver to the other party and the applicable member(s) of its respective Group originals of all books, records, contracts, receipts for deposits and all other papers or documents in its possession which pertain exclusively to the business of the other party and relate to such Service; provided that a party may retain copies of material provided to the other party pursuant to this Section 6.2 as it deems necessary or appropriate in connection with its financial reporting obligations or internal control practices and policies.

ARTICLE VII

DEFAULT

Section 7.1 Termination for Default. In the event (i) of a failure of RemainCo to pay for Services in accordance with the terms of Section 4.1, or (ii) any party shall default, in any material respect, in the due performance or observance by it of any of the other terms, covenants or agreements contained in this Agreement, then (1) if the non-defaulting party is SpinCo, SpinCo shall have the right, at its sole discretion, to immediately terminate the Service with respect to which the default occurred, and (2) if the non-defaulting party is RemainCo, RemainCo shall have the right, at its sole discretion, to immediately terminate the Service with respect to which the default occurred/this Agreement, in either case if the defaulting party has failed to cure the default within 30 days of receipt of the written notice of such default. RemainCo’s right to terminate the Service with respect to which the default occurred pursuant to this Article VII and the rights set forth in Section 2.5 shall constitute RemainCo’s sole and exclusive rights and remedies for a breach by SpinCo hereunder (including any breach caused by an Affiliate of SpinCo or other third party providing a Service hereunder).

ARTICLE VIII

INDEMNIFICATION AND WAIVER

Section 8.1 Waiver of Consequential Damages. NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY UNDER THIS AGREEMENT FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES (INCLUDING IN RESPECT OF LOST PROFITS OR REVENUES), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE OR GROSS NEGLIGENCE) ARISING IN ANY WAY OUT OF THIS AGREEMENT, WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATIONS SHALL

THE INDEMNITY, RELEASES AND LIMITATIONS OF LIABILITY IN THIS AGREEMENT (INCLUDING ARTICLES II AND VIII) ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING ANY EXPRESS NEGLIGENCE RULE OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE NEGLIGENCE OR GROSS NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT OR ACTIVE OR PASSIVE) OR OTHER FAULT OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES.

(c) If, at any time, the Availed Party determines that any of its personnel has sought to circumvent, or has circumvented, the Security Regulations, that any unauthorized Availed Party personnel has accessed the Systems, or that any of its personnel has engaged in activities that may lead to the unauthorized access, use, destruction, alteration or loss of data,

FORCE MAJEURE

Section 10.1 Performance Excused. Continued performance of a Service may be suspended immediately to the extent caused by any event or condition beyond the reasonable control of the party suspending such performance (and not involving any willful misconduct of such party), including acts of God, pandemics, floods, fire, earthquakes, labor or trade disturbances, strikes, war, acts of terrorism, civil commotion, electrical shortages or blackouts, breakdown or injury to computing facilities, compliance in good faith with any Law (whether or not it later proves to be invalid), unavailability of materials or bad weather (a “Force Majeure Event”). RemainCo shall not be obligated to pay any amount for Services that it does not receive as a result of a Force Majeure Event (and the parties hereto shall negotiate reasonably to determine the amount applicable to such Services not received).

ARTICLE XI

MISCELLANEOUS

Section 11.1 Entire Agreement. This Agreement, together with the documents referenced herein (including the Schedules and the Master Separation Agreement), constitutes the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior written and oral and all contemporaneous oral agreements

- 12 -

and understandings with respect to the subject matter hereof. To the extent any provision of this Agreement conflicts with the provisions of the Master Separation Agreement, the provisions of this Agreement shall be deemed to control with respect to the subject matter hereof.

Section 11.2 Binding Effect; No Third-Party Beneficiaries; Assignment. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns; and nothing in this Agreement, express or implied, is intended to confer upon any other person or entity any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement. This Agreement may not be assigned by either party hereto, except with the prior written consent of the other party hereto.

Section 11.3 Amendment; Waivers. No change or amendment may be made to this Agreement except by an instrument in writing signed on behalf of both of the parties hereto. No failure or delay on the part of either party hereto in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty, covenant or agreement contained herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right.

Section 11.4 Notices. Unless otherwise expressly provided herein, all notices, claims, certificates, requests, demands and other communications hereunder shall be in writing and shall be deemed to be duly given (i) when personally delivered or (ii) if mailed by registered or certified mail, postage prepaid, return receipt requested, on the date the return receipt is executed or the letter is refused by the addressee or its agent or (iii) if sent by overnight courier which delivers only upon the signed receipt of the addressee, on the date the receipt acknowledgment is executed or refused by the addressee or its agent or (iv) if sent by facsimile or electronic mail, on the date confirmation of transmission is received (provided that a copy of any notice delivered pursuant to this clause (iv) shall also be sent pursuant to clause (i), (ii) or (iii)), addressed to the attention of the addressee’s General Counsel at the address of its principal executive office or to such other address or facsimile number for a party hereto as it shall have specified by like notice.

Section 11.5 Counterparts. This Agreement and the other documents referred to herein, may be executed in multiple counterparts, each of which when executed shall be deemed to be an original but all of which together shall constitute one and the same agreement.

Section 11.6 Severability. If any term or other provision of this Agreement or the Schedules attached hereto is determined by a nonappealable decision by a court, administrative agency or arbitrator to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the court, administrative agency or arbitrator shall interpret this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible. If any sentence in this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

- 13 -

Section 11.7 Governing Law. This Agreement shall be governed by, and construed and enforced in accordance with, the substantive laws of the State of Delaware, without regard to any conflicts of law provisions thereof that would result in the application of the laws of any other jurisdiction.

Section 11.8 Performance. Each party hereto shall cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary or Affiliate of such party.

Section 11.9 Relationship of Parties. This Agreement does not create a fiduciary relationship, partnership, joint venture or relationship of trust or agency between the parties. The parties hereto agree that SpinCo (and any other member of the SpinCo Group which performs Services hereunder) is an independent contractor in the performance of Services for the RemainCo Group under this Agreement.

Section 11.10 Regulations. All employees of SpinCo and the members of the SpinCo Group shall, when on the property of RemainCo, conform to the rules and regulations of RemainCo concerning safety, health and security which are made known to such employees in advance in writing.

Section 11.11 Construction. This Agreement shall be construed as if jointly drafted by the parties hereto and no rule of construction or strict interpretation shall be applied against either party. In this Agreement, unless the context clearly indicates otherwise, words used in the singular include the plural and words used in the plural include the singular; and if a word or phrase is defined in this Agreement, its other grammatical forms, as used in this Agreement, shall have a corresponding meaning. Whenever the context requires, the gender of all words used in this Agreement includes the masculine, feminine and the neuter. Unless the context otherwise requires, the words “include,” “includes” and “including” shall be deemed to be followed by the words “without limitation,” and the word “or” shall have the inclusive meaning represented by the phrase “and/or.” The words “shall” and “will” are used interchangeably in this Agreement and have the same meaning. Relative to the determination of any period of time hereunder, “from” means “from and including,” “to” means “to but excluding” and “through” means “through and including.” Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless Business Days are specified. Any reference herein to any Article, Section or Schedule means such Article or Section of, or such Schedule to, this Agreement, as the case may be, and references in any Section or definition to any clause means such clause of such Section or definition. As used in this Agreement, the words “this Agreement,” “herein,” “hereunder,” “hereof,” “hereto” and words of similar import shall be deemed references to this Agreement as a whole and not to any particular Section or other provision of this Agreement. The titles to Articles and headings of Sections contained in this Agreement, in any Schedule and in the table of contents to this Agreement have been inserted for convenience of reference only and shall not be deemed to be a part of or to affect the meaning or interpretation of this Agreement.

Section 11.12 Effect if Separation does not Occur. If the Distribution does not occur, then all actions and events that are, under this Agreement, to be taken or occur effective as of or following the Distribution Date, or otherwise in connection with the Distribution, shall not be taken or occur except to the extent specifically agreed by the parties and neither party shall have any liability or further obligation to the other party under this Agreement.
