 SECTION 2.1. Payment of Taxes. 
 (a) Income Taxes. With respect to
any Income Tax Return required to be filed after the Distribution Date, the Party responsible for the filing thereof pursuant to Sections 3.1 and 3.2 shall pay to the relevant Taxing Authority all Taxes due or payable in connection with filing such
Income Tax Return and shall be entitled to any refunds (including, for the avoidance of doubt, any similar credit or offset against Taxes) in connection therewith. Notwithstanding the foregoing, (i) L-3 shall be liable for, and shall be
entitled to any refunds of, Taxes with respect to any Covered Spinco State Income Tax Return and (ii) with respect to any state or local Income Tax Return of Spinco or any Spinco Subsidiary for any taxable period that includes but does not end
on the Distribution Date, L-3 shall be liable for, and shall be entitled to any refunds of, Taxes relating to the portion of the taxable period ending on or before the Distribution Date and Spinco shall be liable for, and shall be entitled to any
refunds of, Taxes relating to the portion of the taxable period beginning after the Distribution Date. For the purpose of (ii) above, Taxes shall be apportioned between the two portions of such taxable period in accordance with the Closing of
the Books Method. 
 (b) Adjusted Income Taxes. Notwithstanding Section 2.1(a), in the event of any subsequent
adjustment to the amount of any Income Taxes relating to a taxable period beginning before the Distribution Date, Spinco shall be liable for its share of any increase in Taxes and shall be entitled to its share of any refunds (Spinco’s share of
any increase in Taxes or refunds, “Spinco’s Share”), and L-3 shall be liable for all other increases in Taxes and shall be entitled to all other refunds. Spinco’s Share shall be determined in the reasonable discretion of
L-3 in accordance with the following principles: 
 (i) In the case of any Income Tax Return that relates solely
to the Spinco Business, Spinco’s Share shall include any increase in Taxes or refunds attributable to such Income Tax Return; and 
 (ii) In the case of any Income Tax Return that relates to both the Spinco Business and the L-3 Business, Spinco’s Share shall be determined by comparing the amount of Taxes with respect to such
Income Tax Return attributable to (x) Tax items relating to the Spinco Business and (y) Tax items not specifically related to either the Spinco Business or the L-3 Business (including, without limitation, corporate overhead) allocable to
Spinco based on a methodology reasonably determined by L-3 with and without the adjustments relating to the items listed in (x) and (y) above. 
 (c) Other Taxes. Spinco shall be liable for, and shall be entitled to any refunds of, all Other Taxes (excluding any such Taxes covered by Section 4.4 (g)) which Spinco or any Spinco
Subsidiary is required to pay, or is entitled to receive, after the Distribution Date under applicable law. L-3 shall be liable for, and shall be entitled to any refunds of, all Other Taxes (excluding any such Taxes covered by Section 4.4 (g))
which L-3 or any L-3 Subsidiary is required to pay, or is entitled to receive, after the Distribution Date under applicable law. 

  
 4 

 (d) Distribution Taxes. Notwithstanding anything in this Section 2.1 to the
contrary, and except as provided in Article IV, L-3 shall be liable for, and shall be entitled to any refunds of, any Income Taxes imposed or incurred as a result of (i) the Distribution failing to qualify under Section 355 of the Code,
(ii) the stock of Spinco distributed in the Distribution failing to be treated as qualified property pursuant to Section 355(d) or 355(e) of the Code or (iii) L-3 otherwise recognizing any gain in connection with the Distribution
(including, for the avoidance of doubt, the related internal transactions described in the Ruling). 
 (e) State
Combinations. Notwithstanding anything in this Section 2.1 to the contrary, L-3 shall be liable for any incremental state Income Taxes, and shall be entitled to receive the benefit of any reduction in state Income Taxes, resulting from a
Final Determination after the Distribution Date requiring L-3 or any of its Subsidiaries (including, for the avoidance of doubt, Subsidiaries of L-3 before the Distribution Date) that file on a separate basis to file a combined, consolidated, or
unitary group Tax Return for a taxable period beginning before the Distribution Date. 
 SECTION 2.2. Indemnity.

 (a) Subject to Article IV, L-3 shall indemnify Spinco from all liability for Taxes for which L-3 is responsible pursuant to
Section 2.1. 
 (b) Spinco shall indemnify L-3 from all liability for Taxes for which Spinco is responsible pursuant to
Section 2.1. 
 (c) Unless otherwise agreed in writing, the indemnifying Party shall pay to the indemnified Party the
amount required to be paid pursuant to Section 2.2(a) or (b) above within fifteen (15) days of being notified of the amount due by the indemnified Party, but no earlier than two Business Days prior to the date payment of such amount
is required to be made to the applicable Taxing Authority. The notice by the indemnified Party requesting such payment shall be accompanied by the calculations and other information used to determine the indemnifying Party’s obligations
hereunder. Such payment shall be paid by the indemnifying Party to the indemnified Party by wire transfer of immediately available funds to an account designated by the indemnified Party by written notice to the indemnifying Party prior to the due
date of such payment. 
 SECTION 2.3. Contests. 
 (a) Subject to Article IV, the sole right to control the conduct of any Proceeding shall belong to the Party responsible, pursuant to Sections 3.1 and 3.2, for the filing of the Tax Return to which such
Proceeding relates; provided, however, that any Income Tax Proceeding commencing before the Distribution Date shall be controlled and directed exclusively by L-3. 
 (b) After the Distribution Date, each Party shall promptly notify the other Party in writing upon receipt of written notice of the commencement of any Proceeding or of any demand or claim upon it, which,
if determined adversely, would be grounds for indemnification from such other Party pursuant to Section 2.2 or could reasonably be expected to have an adverse Tax effect on the other Party. Each Party shall, on a timely basis, keep the other
Party informed of all developments in the Proceeding and provide such other Party with copies of all pleadings, briefs, orders, and other correspondence pertaining thereto. 

  
 5 

 SECTION 2.4. Treatment of Payments; After Tax Basis. 

(a) L-3 and Spinco agree to treat any indemnification payments (other than payments of interest pursuant to Section 2.4(c)) pursuant
to this Agreement as either a capital contribution or a distribution, as the case may be, between L-3 and Spinco occurring immediately prior to the Distribution. If the receipt or accrual of any such payment (other than payments of interest pursuant
to Section 2.4(c)) results in taxable income to the indemnified Party, such payment shall be increased so that, after the payment of any Taxes with respect to the payment, the indemnified Party shall have realized the same net amount it would
have realized had the payment not resulted in taxable income. 
 (b) To the extent that any liability for Taxes, that is subject
to indemnification under Section 2.2, gives rise to a deduction, credit or other Tax benefit to the indemnified Party, the amount of any payment made under Section 2.2 shall be decreased by taking into account any actual reduction in Taxes
of the indemnified Party resulting from such Tax benefit. If a reduction in Taxes of the indemnified Party occurs in a taxable period following the period in which the indemnification payment is made, the indemnified Party shall promptly repay the
indemnifying Party the amount of such reduction when actually realized. 
 (c) Payments made pursuant to this Agreement that are
not made within the period prescribed in this Agreement or, if no period is prescribed, within thirty (30) days after demand for payment is made (the “Payment Period”) shall bear interest for the period from and including the
date immediately following the last date of the Payment Period through and including the date of payment at a rate of simple interest per annum equal to the Applicable Rate. Such interest will be payable at the same time as the payment to which it
relates and shall be calculated on the basis of a year of 365 days and the actual number of days for which due. 
 ARTICLE III.
PREPARATION AND FILING OF TAX RETURNS 
 SECTION 3.1. L-3’s Responsibility for the Preparation and Filing of Tax

 6 

 SECTION 3.3. Manner of Preparation.

Period”), and a separate Income Tax Return for each Stub Taxable Period shall be prepared and filed by the Party responsible for such preparation and filing pursuant to Sections 3.1 and 3.2. 

(b) To the extent any Tax Return required to be prepared by L-3 pursuant to Section 3.1 contains items relating to the Spinco
Business or any Tax Return required to by prepared by Spinco pursuant to Section 3.2 contains items relating to the L-3 Business, the Party not responsible for preparing such Tax Return (the “Included Party”) shall, at its own
cost and expense, prepare and deliver to the Party responsible for preparing such Tax Return (the “Preparing Party”) a true and correct accounting of all relevant Tax Items relating to the Included Party (or any of its Subsidiaries)

change in law, all Income Tax Returns of Spinco and its Subsidiaries for taxable periods beginning before the Distribution Date shall be prepared consistent with the Tax Returns of the Affiliated Group. 

(e) Except to the extent required by law, Spinco shall not amend any Income Tax Return relating to a taxable period (or portion thereof)
ending on or before to the Distribution Date without the written consent of L-3, not to be unreasonably withheld. 
 SECTION
3.4. Carrybacks. To the extent permitted by law, Spinco and its Subsidiaries shall elect to forego a carryback of any net operating losses, capital losses or credits for any taxable period ending after the Distribution Date to a taxable

transfer all or substantially all of its assets (within the meaning of Rev. Proc. 77-37, 1977-2 C.B. 568) in a single transaction or series of related transactions, or sell or transfer any portion of Spinco’s assets that would violate the

of options or otherwise), option grants, capital contributions or acquisitions, entering into any partnership or joint venture arrangements, or a series of such transactions or events, but excluding the Distribution) that may cause the Distribution
to be treated as part of a plan pursuant to which one or more persons acquire directly or indirectly stock of Spinco representing a “50-percent or greater interest” therein within the meaning of Section 355(d)(4) of the Code, or
(vii) take any other action , or permit any Spinco Subsidiary to take any such action, where the taking of such action could reasonably be expected to cause the Distribution to fail to qualify under Section 355 of the Code or cause the
stock of Spinco distributed in the Distribution to fail to be treated as qualified property pursuant to Section 355(e) of the Code (the acts listed in (i)-(vii) collectively, the 

  
 8 

 
“Prohibited Acts”). Notwithstanding the foregoing, Spinco may take any of the Prohibited Acts, subject to Section 4.3, if (x) Spinco first obtains (at its expense) an
opinion in form and substance reasonably acceptable to L-3 of a nationally recognized law firm or a “big four” accounting firm reasonably acceptable to L-3, which opinion may be based on usual and customary factual representations
(reasonably acceptable to L-3) or (y) at Spinco’s request, L-3 (at the expense of Spinco) obtains a supplemental ruling from the IRS, that such Prohibited Act or Acts, and any transaction related thereto, will not (a) affect any of
the conclusions set forth in the Ruling, including (i) the qualification of the Distribution and certain internal transactions preceding the Distribution under Sections 355 and 368 of the Code and (ii) the nonrecognition of gain to L-3 in
the Distribution, or (b) cause the stock of Spinco distributed in the Distribution to fail to be treated as qualified property pursuant to Sections 355(d) or 355(e) of the Code. Spinco may also take any of the Prohibited Acts, subject to
Section 4.3, with the consent of L-3 in its sole and absolute discretion. During the Restricted Period, Spinco shall provide all information reasonably requested by L-3 relating to any transaction involving an acquisition (directly or
indirectly) of Spinco stock within the meaning of Section 355(e) of the Code. 
 SECTION 4.3. Indemnification by
Spinco. If, after the Distribution, Spinco or any of its Affiliates takes any action or enters into any agreement to take any action, including any of the Prohibited Acts as defined in Section 4.2 of this Agreement, or if there is a breach
by Spinco of Section 4.1 hereof, or if there is any direct or indirect acquisition of Spinco stock, and as a result (i) the Distribution shall fail to qualify under Section 355 of the Code, (ii) the stock of Spinco distributed in
the Distribution shall fail to be treated as qualified property pursuant to Section 355(d) or 355(e) of the Code or (iii) L-3 otherwise recognizes any gain in connection with the Distribution (including, for the avoidance of doubt, the
related internal transactions described in the Ruling), then Spinco shall indemnify and hold harmless L-3 against any and all Taxes imposed upon or incurred by L-3 (and any Taxes of L-3 shareholders to the extent L-3 is liable with respect to such
Taxes, whether to a Taxing Authority, to a shareholder or to any other person) as a result, unless such Taxes would, in any event, have been imposed upon or incurred by L-3 without regard to such actions, breaches or events, as determined at such
time. L-3 shall be indemnified and held harmless under this Section 4.3 without regard to whether an opinion or supplemental ruling pertaining to the action pursuant to Section 4.2 was obtained, and without regard to whether L-3 gave its
consent to such action pursuant to Section 4.2 or otherwise. 
 SECTION 4.4. Procedural Matters. 

(a) Notice. If either Spinco or L-3 receives any written notice of deficiency, claim or adjustment or any other written
communication from a Taxing Authority that may result in an Indemnified Liability, the Party receiving such notice or communication shall promptly give written notice thereof to the other Party, provided that any delay by L-3 in so notifying Spinco
shall not relieve Spinco of any liability to L-3 hereunder except to the extent Spinco is materially and adversely prejudiced by such delay. L-3 undertakes and agrees that from and after such time as L-3 obtains knowledge that any representative of
a Taxing Authority has begun to investigate or inquire into the Distribution (whether or not such investigation or inquiry is a formal or informal investigation or inquiry), L-3 shall (i) notify Spinco thereof, provided that any delay by L-3 in
so notifying Spinco shall not relieve Spinco of any liability to L-3 hereunder except to the extent Spinco is materially and adversely prejudiced by such delay, (ii) consult with Spinco from time to time as to the conduct of such investigation
or inquiry, (iii) provide Spinco with copies of all correspondence between L-3 or its representatives and such Taxing Authority or any representative thereof pertaining to such investigation or inquiry and (iv) cooperate with Spinco to
permit a representative (reasonably satisfactory to L-3) of Spinco to be present at, and participate in (but not control), all meetings with such Taxing Authority or any representative thereof pertaining to such investigation or inquiry, provided,
that any costs relating to Spinco’s representation at such meetings shall be borne by Spinco.

 (b) Tax Proceedings Controlled by L-3. With respect to any Proceeding that may result
in an Indemnified Liability, L-3 shall assume and direct the defense or settlement of such Proceeding, provided that Spinco shall be entitled to participate in such Proceeding at its own cost and expense; provided, however, that L-3 shall not
settle, compromise or concede any such Proceeding without Spinco’s consent, not to be unreasonably withheld. 
 (c) Tax
Proceedings Controlled by Spinco. If Spinco withholds consent to the settlement, compromise or concession of any Proceeding that is the subject of Section 4.4(b), Spinco may, upon confirmation in writing to L-3 that the liability asserted
in such Proceeding would, if imposed upon or incurred by L-3 or its Subsidiaries, be an Indemnified Liability, assume and direct the defense or settlement of the Proceeding, subject to the participation and consultation of L-3, provided that, if L-3
reasonably determines that Spinco has failed to prosecute the Proceeding in a reasonable and diligent manner, L-3 may (at Spinco’s expense and subject to the provisions in Section 4.4(d)) reassume and direct the defense or settlement of
the Proceeding. The following provisions shall apply to any Proceeding control of which is assumed by Spinco pursuant to the preceding sentence. 
         (i) Upon request, during the course of the Proceeding, Spinco shall from time to time furnish L-3 with evidence reasonably satisfactory to L-3 of its
ability to pay the full amount of the Indemnified Liability. If at any time during such Proceeding, L-3 reasonably determines, after due investigation, that Spinco may not be able to pay the full amount of the Indemnified Liability, if required,
then Spinco shall be required to furnish a guarantee or performance bond satisfactory to L-3 in an amount equal to the amount of the Indemnified Liability asserted by the Taxing Authority. If Spinco fails to furnish such guarantee or bond, L-3 may
reassume control of the Proceedings in accordance with Section 4.4(d). 

        (ii) Spinco shall pay all expenses directly related to the Indemnified
Liability, including but not limited to reasonable fees for attorneys, accountants, expert witnesses or other consultants retained by it. 
         (iii) L-3 shall, at Spinco’s sole cost (including but not limited to any reasonable out-of-pocket costs incurred by L-3), take such action as Spinco
may reasonably request (including but not limited to the execution of powers of attorney for one or more persons designated by Spinco) in contesting the Indemnified Liability. Spinco shall, on a timely basis, keep L-3 informed of all developments in
the Proceeding and provide L-3 with copies of all pleadings, briefs, orders, and other written papers pertaining thereto. 
         (iv) Subject to satisfaction of the conditions herein set forth, Spinco may direct L-3 to settle the Indemnified Liability on such terms and for such amount
as Spinco may direct. L-3 may condition such settlement on receipt, prior to the settlement, from Spinco of the indemnity payment with respect to the Indemnified Liability less any amounts to be paid directly by Spinco to the Taxing Authority.
Spinco may direct L-3, at Spinco’s expense, to pay an asserted deficiency for the Indemnified Liability out of funds provided by Spinco, and to file a claim for refund. 
 If Spinco withholds consent to the settlement, compromise or concession of any Proceeding that is the subject of Section 4.4(b) and does not assume control of such Proceeding pursuant to this
Section 4.4(c) within thirty (30) days following the request by L-3 for such consent, such Proceeding shall be controlled and directed exclusively by L-3 
 (d) Resumption by L-3 of Control of Tax Proceedings. With respect to any Proceeding control of which is assumed by Spinco pursuant to Section 4.4(c), should (i) Spinco fail within thirty
(30) days 

  
 10 

 
following request therefor to furnish to L-3 evidence of its ability to pay the full amount of the Indemnified Liability, (ii) L-3 reasonably believe after due investigation that Spinco may
not be able to pay the full amount of the Indemnified Liability, if required, and Spinco fails to furnish a guarantee or performance bond satisfactory to L-3 in an amount equal to the amount of the Indemnified Liability then being asserted by the
Taxing Authority, or (iii) L-3 reasonably determine that Spinco has failed to prosecute the Proceeding in a reasonable and diligent manner, then L-3 may reassume control of the Proceeding and may settle such Proceeding in its discretion.

 (e) Time and Manner of Payment. Unless otherwise agreed in writing, Spinco shall pay to L-3 the amount with respect to
an Indemnified Liability (less any amount paid directly by Spinco to the Taxing Authority or made available to L-3 under Section 4.4(d)) at least two Business Days prior to the date payment of the Indemnified Liability is required to be made to
the Taxing Authority. Such payment shall be paid by Spinco to L-3 by wire transfer of immediately available funds to an account designated by L-3 by written notice to Spinco prior to the due date of such payment. 

(f) Refund of Amounts Paid by Spinco. Should L-3 or any other member of the Affiliated Group receive a refund in respect of
amounts paid by Spinco to any Taxing Authority on L-3’s behalf or paid by Spinco to L-3 for payment to a Taxing Authority with respect to an Indemnified Liability, or should any such amounts that would otherwise be refundable to L-3 be applied
or credited by the Taxing Authority to obligations of L-3 unrelated to an Indemnified Liability, then L-3 shall, promptly following receipt (or notification of credit), remit such refund (including any statutory interest that is included in such
refund or credited amount) to Spinco. 
 (g) Transfer Taxes. Notwithstanding anything herein to the contrary, L-3 shall
bear any and all stamp, duty, transfer, sales and use or similar Taxes incurred in connection with the Distribution. 
 (h)
Cooperation. Subject to the provisions of Section 3.6, L-3 and Spinco shall reasonably cooperate with one another in a timely manner in any Proceeding involving any matter that may result in an Indemnified Liability. L-3 and Spinco agree
that such cooperation shall include, without limitation, making available to the other Party, during normal business hours, all books, records and information, officers and employees (without substantial interruption of employment) necessary or
useful in connection with any such judicial or administrative Proceeding. The Party requesting or otherwise entitled to any books, records, information, officers or employees pursuant to this Section 4.4(h) shall bear all reasonable
out-of-pocket costs and expenses (except reimbursement of salaries, employee benefits and general overhead) incurred in connection with providing such books, records, information, officers or employees. 

(i) Supplemental Rulings. L-3 shall provide Spinco a copy of and an opportunity to comment upon any supplemental ruling sought
from the IRS with respect to the Ruling and no supplemental ruling request shall be made without Spinco’s consent if such supplemental ruling would materially expand Spinco’s indemnification obligations under Section 4.3.

 3 

 ARTICLE III 
 SERVICES 
 Section 3.01 Services Generally. 

(a) Except as otherwise provided in the Transition Service Schedule, for the Term hereof, L-3 shall provide or cause to be provided to
Engility the Services described in the Transition Service Schedules. 
 (b) Each of the services on the Transition Service
Schedule shall be referred to herein as a “Service.” Collectively, the services described on all the Transition Service Schedules shall be referred to herein as the “Services.” 

(c) During the Term (as defined below), Service Recipient may request any Service that it deems reasonably necessary for the ongoing
operation of the Spinco Business in substantially the manner that it was conducted immediately prior to the Distribution. Service Provider will use Commercially Reasonable Efforts to provide all such requested Services to Service Recipient, but only
if such Services were provided to Service Recipient prior to the Distribution Date, except in the event of an Impracticability or as otherwise provided in this Agreement. 
 Section 3.02 Service Levels. Except as otherwise provided in the Transition Service Schedule for a specific Service: (a) the Service Provider shall provide the Services only to the extent
such Services are being provided immediately prior to the Distribution Date and at a level of service substantially similar to that provided immediately prior to the Distribution Date and (ii) the Services will be available only for purposes of
conducting the business of the Service Recipient substantially in the manner it was conducted prior to the Effective Time; provided, however, that nothing in this Agreement will require the Service Provider to favor the Service Recipient over its
other business operations. All Services are provided on an “as is” basis, and L-3 is permitted to modify all Services as it sees fit in the ordinary course of its business. 

Section 3.03 Impracticability. The Service Provider shall not be required to provide any Service to the extent the
performance of such Service becomes impracticable due to cause or causes outside the reasonable control of the Service Provider, including, without limitation, failure of the Service Recipient to comply with Section 6.01, unfeasible
technological requirements, or to the extent the performance of such Services would require the Service Provider to violate any applicable Law, or would result in the breach of any license, Governmental Authorization or Contract (each, an
“Impracticability”). 
 Section 3.04 Additional Resources. In accordance with Section 6.07 below and
except as specifically provided in a Transition Service Schedule for a specific Service, in providing the Services, the Service Provider shall not be obligated to: (a) hire any additional employees; (b) maintain the employment of any
specific employee; (c) purchase, lease or license any additional facilities, equipment or software; or (d) pay any costs related to the transfer or conversion of the Service Recipient’s data to the Service Provider or any alternate
supplier of Services. 

  
 4 

 Section 3.05 Additional Services. The Transition Service Schedules may be
amended at any time by mutually agreed upon amendment of this Agreement to add additional Services. The charges for such additional Services shall be as set forth in the amended Transition Service Schedules. 

ARTICLE IV 
 TERM

 The term of this Agreement shall commence on the Distribution Date and end 18 months following the Distribution Date,
unless earlier terminated under Article VII (the “Term”, and the last day of the Term, the “Expiration Date”). The Parties may agree on an earlier expiration date respecting a specific Service by specifying such
date on the Transition Service Schedule for that Service. Services shall be provided up to and including the date set forth in the applicable Transition Service Schedule, subject to earlier termination as provided in Article VII. It shall be the
sole responsibility of the Service Recipient, upon and after expiration or early termination of this Agreement with respect to a specific Service, to perform, render and provide for itself (or to make arrangements with one or more Third Party
service providers to perform, render and provide) such Service, and to do all necessary planning and make all necessary preparations in connection therewith. 
 ARTICLE V 
 COMPENSATION 

Section 5.01 Charges for Services. The Service Recipient shall pay (a) the Service Provider or (b) the Third Party
service provider, as applicable, (i) the Dollar value charges, or (ii) the charges determined by the method, in either case, if any, set forth on the Transition Service Schedules for each of the Services listed therein, or, if no such
charges are specifically indicated otherwise, by the Fair Market Value of the Services. If there is any inconsistency between the Transition Services Schedule and this Section 5.01, the terms of the Transition Service Schedule shall govern.

 Section 5.02 Payment Terms. Except as otherwise specified in a Transition Service Schedule, the Service Provider
shall invoice the Service Recipient monthly (or on such other basis as the Parties may mutually determine) for all charges for Services to be paid to the Service Provider as set forth on the Transition Service Schedules pursuant to this Agreement.
Such invoices shall generally identify the Services provided to the Service Recipient during the preceding month and specify the Service fee applicable to each Service so identified. Except as otherwise specified in a Transition Service Schedule,
the Service Recipient shall pay the Service Provider for all such Services within 30 days after receipt of an invoice therefor by wire transfer of immediately available funds to the account designated by the Service Provider for this purpose.
Late payments shall bear interest at a rate per annum equal to the Prime Rate plus 2.0%, calculated for the actual number of days elapsed, accrued from and excluding the date on which such payment was due up to and including the date of payment.
Late payment for any Service provided hereunder shall entitle Service Provider to suspend, at Service Provider’s sole discretion, the provision of any or all Services to Service Recipient hereunder. 

  
 5 

 Section 5.03 Taxes. The fees and charges payable by the Service Recipient under
this Agreement and set forth on the Transition Service Schedules shall be exclusive of any Sales Taxes or excise Taxes or any customs or import charges or duties or any similar charges or duties which may be imposed by any Governmental Entity in
connection with the purchase or delivery of the Services or materials to the Service Recipient. The Service Recipient shall remit to the Service Provider any Sales Taxes properly payable to the Service Provider pursuant to this Agreement. Applicable
Sales Taxes shall be indicated by the Service Provider separately on all of the Service Provider’s invoices. The Parties shall cooperate with each other to minimize any applicable Sales Taxes and each shall provide the other with any reasonable
certificates or documents which are useful for such purpose. 
 Section 5.04 Records and Audits. Service Provider
shall maintain detailed books and records of the costs on which the fees charged to Service Recipient hereunder have been based. Service Recipient shall have the right, at its sole cost and expense, to have the applicable books and records of
Service Provider audited by a nationally recognized independent certified public accountant, mutually selected by the Parties, under appropriate confidentiality provisions, for the purpose of verifying the accuracy of all fees and out-of-pocket cost
calculations under this Agreement. Any such audit shall be conducted no more than twice during the Term and shall be conducted upon at least thirty (30) days’ advance notice during normal business hours and in a manner that does not
interfere unreasonably with Service Provider’s business. The results of any such audit shall be binding on the Parties absent manifest error, and shall be delivered in writing to each Party. Any underpayment or overbilling determined by such
audit shall promptly be paid by Service Recipient or refunded by Service Provider, as applicable, plus interest at a rate of simple interest per annum equal to the Applicable Rate, from the date of any such underpayment or overbilling. 

ARTICLE VI 

GENERAL OBLIGATIONS 
 Section 6.01 Performance Metrics. Subject to Article III and any other term or condition of this Agreement, each Party shall maintain sufficient resources to perform their obligations
hereunder. Any specific performance metrics for the Service Provider or the Third Party service provider for a specific Service may be set forth in the corresponding Transition Service Schedule. Where none is set forth, the Service Provider shall
(consistent with the other terms and conditions of this Agreement) use Commercially Reasonable Efforts to provide Services, or to cause the Services to be provided, in accordance with the policies, procedures, service levels and practices in effect
before the Distribution Date and shall exercise the same care and skill as the Service Provider exercises in performing similar services for itself. To the extent within the possession and control of the Service Recipient, the Service Recipient
shall (i) provide, and shall cause the other relevant members of the Engility Group to provide, the Service Provider with any and all information and documentation, and (ii) take actions and make decisions in a timely manner, in each case
sufficient for the Service Provider to perform the Services it is obligated to perform hereunder (and to perform its obligation to cause the Services to be provided, where applicable) as they were performed before the Distribution Date and shall
make available, as reasonably requested by the Service Provider, sufficient resources and timely decisions, approvals and acceptances in order that the Service Provider may perform its obligations hereunder in a timely manner. 

  
 6 

 Section 6.02 Disclaimer of Warranties. No Party makes any warranties or
conditions, express, implied, conventional or statutory, including but not limited to, the implied warranties or conditions of merchantability, of quality or fitness for a particular purpose, with respect to the Services or other items or
deliverables provided by it or any Third Party service provider. 
 Section 6.03 Transitional Nature of Services;
Changes. The Parties acknowledge the transitional nature of the Services and that the Service Provider may make changes from time to time in the manner of performing the Services if the Service Provider is making similar changes in performing
similar services for itself. 
 Section 6.04 Responsibilities for Errors; Changes. Except as set forth in Article
XIII, the Service Provider’s sole responsibility to the Service Recipient: 
 (a) for material errors or
omissions in Services, shall be to furnish correct information, payment and/or adjustment in the Services, at no additional cost or expense to the Service Recipient; provided, that the Service Provider must promptly advise the Service
Recipient of any such material error or omission of which it becomes aware; and 
 (b) for failure to deliver any
Service because of Impracticability, shall be to use Commercially Reasonable Efforts, subject to Section 3.03, to make the Services available or to resume performing the Services as promptly as reasonably practicable. 

Section 6.05 Cooperation and Consents. The Parties shall cooperate with each other in all matters relating to the provision
and receipt of Services. Such cooperation shall include exchanging information, performing true-ups and adjustments and obtaining all Third Party Consents, licenses or sublicenses necessary to permit each Party to perform its obligations hereunder
(including by way of example, not by way of limitation, rights to use Third Party software needed for the performance of Services). Pursuant to Section 10.03, the costs of obtaining such Third Party Consents, licenses or sublicenses shall be
borne by the Service Recipient. 
 Section 6.06 Alternatives. If the Service Provider reasonably believes it is
unable to provide any Service because of a failure to obtain necessary Consents, licenses or sublicenses pursuant to Section 6.05 or because of Impracticability, the Parties shall reasonably and in good faith cooperate to determine the best
alternative approach. Until such alternative approach is found or the problem otherwise resolved to the reasonable satisfaction of the Parties, the Service Provider shall not be obligated to continue providing the Service. To the extent an agreed
upon alternative approach requires the occurrence of costs or expenditures above and beyond that which is included in the Service Provider’s charge for the Service in question, such additional costs and expenditures shall be discussed between
the Parties and, unless otherwise agreed, be borne by the Service Recipient. 
 Section 6.07 Personnel. 

(a) Right to Designate and Change Personnel. The Service Provider will have the right to designate which personnel it will assign
to perform the Services. The Service Provider also will have the right to remove and replace any such personnel at any time or 

  
 7 

 
designate any of its Affiliates or a Subcontractor at any time to perform the Services, pursuant to Article IX; provided, however, that the Service Provider will use Commercially Reasonable
Efforts to limit the disruption to the Service Recipient in the transition of the Services to different personnel or to a Subcontractor. In the event that personnel with the designated level of experience are not then employed by the Service
Provider, the Service Provider will use Commercially Reasonable Efforts to provide such personnel or Subcontractor personnel having an adequate level of experience; provided, however, that the Service Provider will have no obligation to retain any
individual employee for the sole purpose of providing the applicable Services. 
 (b) Financial Responsibility. The
Service Provider will directly pay for all personnel expenses, including wages, of its employees performing the Services. 
 (c)
Service Managers and Service Recipient Representatives. During the Term of this Agreement, the Parties will appoint (i) in the case of the Service Provider, one of its employees (the “Service Manager”) for each Service
as indicated in each Transition Service Schedule who will have responsibility for managing and coordinating the delivery of such Service and (ii) in the case of the Service Recipient, one of its employees (the “Service Recipient
Representative”) for each Service as indicated in each Transition Service Schedule who will have responsibility for managing and coordinating the Service Recipient’s utilization of such Service. The Service Managers will coordinate and
consult with the Service Recipient Representatives. The Parties may, at their discretion, select other individuals to serve in these capacities during the Term of this Agreement upon providing notice to the other Party. For greater certainty, a
Service Manager or a Service Recipient Representative may serve as such in respect of one or more Transition Service Schedules. 

Section 6.08 Insurance. Each Party shall obtain and maintain at its own expense insurance of the type generally maintained in
the ordinary course of its business. The Service Provider shall not be required to obtain and maintain any particular insurance in relation to providing any Service. 
 ARTICLE VII 
 TERMINATION 

Section 7.01 Termination. Service Recipient may terminate any Service, with or without cause, at any time upon at least 60
days’ prior notice to the Service Provider, except with respect to the Services described on Transition Service Schedule No. 1 (Ethics Training Module System), No. 2 (Health/Welfare Plans), No. 3 (Health/Welfare Services
Support), No. 11 (File 2012 Federal Income Tax Return) and No. 12 (Travel Program), each of which Services shall remain in effect until the termination date for such Service as indicated on the applicable Transition Service Schedule. As
soon as reasonably practicable following receipt of any such early termination notice, the Service Provider shall advise the Service Recipient as to whether termination of such Service will (a) require the termination or partial termination of,
or otherwise affect the provision of, certain other Services or (b) result in any early termination costs, including those related to Subcontractors. In the event that such termination is expected by the Service Provider to result in any early
termination costs, the Service Provider will provide to the Service Recipient such information as it has reasonably available regarding the estimated amount 

  
 8 

 
of such costs, which in the case of a Subcontractor may be based upon information provided by such Subcontractor. Any early termination costs shall be borne by the Service Recipient as set forth
in Section 7.03. 
 In addition, the Parties agree that either Party may terminate this Agreement (and the corresponding
Transition Service Schedule) with respect to a specific Service upon providing notice to the other Party in the event that an Event of Default occurs in relation to such other Party, and such termination shall take effect immediately upon the
non-defaulting Party providing such notice to the other (except as otherwise specified in clause (c) below). 
 For the
purposes of this Agreement, each of the following shall individually and collectively constitute an “Event of Default”: 
 (a) in relation to the Service Recipient, if the Service Recipient defaults in payment to the Service Provider of any payments which are due and payable by it to the Service Provider pursuant to this
Agreement, and such default is not cured within 15 days following receipt by the Service Recipient of notice of such default; 
 (b) either Party breaches any of its material obligations to the other Party pursuant to this Agreement (other than as set out in paragraph (a) above), and fails to cure it within 30 days after
receipt of written notice from the non-defaulting Party specifying the default in reasonable detail and demanding that it be rectified; provided, that if such breach is not capable of being cured within 30 days after receipt of such
written notice and the Party in default has diligently pursued efforts to cure the default within the 30 day period, no Event of Default under this paragraph (b) shall occur; and provided, further, that no failure of the Service Provider
to provide any Services shall constitute an “Event of Default” if such failure is a result of the Service Recipient’s failure to comply with its obligations under the final sentence of Section 6.01 in all respects; and

 (c) either Party (i) is bankrupt or insolvent or takes the benefit of any statute in force for bankrupt
or insolvent debtors, or (ii) files a proposal or takes any action or proceeding before any court of competent jurisdiction for its dissolution, winding-up or liquidation, or for the liquidation of its assets, or a receiver is appointed in
respect of its assets, which order, filing or appointment is not rescinded within 60 days. 
 Section 7.02
Survival. Notwithstanding the foregoing, in the event of any termination or expiration with respect to one or more Services, but less than all Services, this Agreement shall continue in full force and effect with respect to any Services not
terminated or expired. Section 5.04 and Articles VII, X, XII, XIII and XV shall survive the termination or expiration of this Agreement in accordance with its terms (where applicable). 

Section 7.03 Payment. Immediately following the Expiration Date, the Service Provider shall cease, or cause its
Subcontractors to cease, providing the Services, and the Service Recipient shall promptly pay or cause the other relevant members of the Engility Group to which it belongs, to promptly pay all fees accrued pursuant to Article V but unpaid to the
Service Provider. 

  
 9 

 Section 7.04 User ID; Passwords. The Parties shall use Commercially Reasonable
Efforts upon the termination or expiration of this Agreement or of any specific Service hereto to ensure that access by one Party to the other Party’s systems is cancelled. 

ARTICLE VIII

compensation, disability benefits and the like of its employees.

Provider to provide any of the Services hereunder.

hereunder shall not be discharged by an amount paid in any currency other than Dollars, whether pursuant to a court order or judgment or arbitral award or otherwise, to the extent that the amount so paid upon conversion to Dollars and transferred to

Provider against, and to pay to the Service Provider on demand, in Dollars, any difference between the sum originally due in Dollars and the amount of Dollars received upon any such conversion and transfer. 

Section 15.05 Entire Agreement. This Agreement, the other Ancillary Agreements, the Distribution Agreement and exhibits,
schedules and appendices hereto (including the Transition Services Schedules) and thereto, and the specific agreements contemplated herein or thereby, contain the entire agreement between the Parties with respect to the subject matter hereof and

any Transition Service Schedule thereto) and the terms of any Transition Service Schedule, the provisions of the Transition Service Schedule shall prevail. 
 Section 15.07 Force Majeure. No Party shall be deemed in default of this Agreement to the extent that any delay or failure in the performance of its obligations under this Agreement results

notice by the Party who is delayed or prevented from performing its obligations to the other Party (i) the affected provisions or other requirements of this Agreement shall be suspended to the extent necessary during the period of such
disability, (ii) the Party which is delayed or prevented from performing its obligations by a Force Majeure Event shall have the right to apportion its Services in an equitable manner to all users and (iii) such Party shall have no

exercising any rights or remedies under this Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, provision, condition, right or remedy or as a waiver of any other term,
provision or condition of this Agreement.

Reasonable Efforts to execute any and all documents and to perform such other acts as may be necessary or expedient to further the purposes of this Agreement and the relations contemplated hereby. Without limiting the foregoing and the provisions of

which relate to the Services and which are necessary to confirm the said Party’s compliance with its obligations under this Agreement. 

  
 15 

 Section 15.10 Severability. The provisions of this Agreement are severable and
should any provision hereof be void, voidable or unenforceable under any applicable Law, such provision shall not affect or invalidate any other provision of this Agreement, which shall continue to govern the relative rights and duties of the
Parties as though such void, voidable or unenforceable provision were not a part hereof.
