	 	(a)	To the maximum extent permitted by Applicable Law, any Member and any Member’s Corporate Affiliates may, notwithstanding this Agreement, engage in whatever activities it
chooses, whether or not the same are competitive with those of the Company, without having or incurring any obligation to offer any interest in such activities to the Company or any other Member. Without limitation of the foregoing, each of AEPTHC
and Duke and their respective Corporate Affiliates may, in its discretion, (i) undertake transmission projects alone or with any other Person or Persons without proposing that such projects be undertaken by the Company, (ii) engage in the
same or similar activities or line of business as the Company or develop or market any services or activities that compete directly or indirectly with those of the Company, or (iii) beneficially own securities of or develop a business
relationship with any Person engaged in the same or similar activities or line of business as, or otherwise in competition with, the Company (the activities, projects and relationships described in this Section 2.9.1(a) are collectively
referred to as “Permitted Activities”). 

  

	 	(b)	Any Member and any of its Corporate Affiliates may independently pursue any project or other Permitted Activities which would otherwise be in the scope of this Agreement (other than
the Initial Project, except to the extent permitted by Section 14.5) without offering such project or Permitted Activities to the Company. Any Member and any of its Corporate Affiliates may further independently pursue any project which
is either considered by the Company or offered to the Company, but in either case, does not become a Company Project. 

  

	 	(c)	Without limiting this Section 2.9.1 in any way, neither the Company nor any Member or any Corporate Affiliates of any Member by virtue of this Agreement shall have any
rights in or to any Permitted Activity or the income or profits derived therefrom of any other Member, regardless of whether or not such Permitted Activity was presented to or otherwise became known to that other Member as a direct or indirect
result of its connection with the Company. No Member or any of its Corporate Affiliates shall have any obligation to present or offer any project or other Permitted Activity to the Company, even if the project or other Permitted Activity is one that
the Company might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and no Member or any Corporate Affiliate thereof shall be liable to the Company or any other Member for breach of any
fiduciary or other duty by reason of the fact that such Member or any Corporate Affiliate thereof pursues or acquires such business opportunity, directs such business opportunity to another Person or fails to present such business opportunity, or
information regarding such business opportunity, to the Company.

Table of Contents

	 	(d)	Without limiting this Section 2.9.1 in any way, in the event that a Manager or an Employed Officer acquires knowledge of a Permitted Activity that may be a corporate
opportunity for the Company or the Members, on the one hand, and the Designating Member of such Manager or employer of such Employed Officer, on the other hand, the Manager or Employed Officer shall have fully satisfied and fulfilled his or her
fiduciary duty, if any, to the Company and the Members (other than the Designating Member of such Manager or employer of such Employed Officer) with respect to such corporate opportunity, and the Company and the Members (other than the Designating
Member of such Manager or employer of such Employed Officer) hereby renounce their respective interest in such business opportunity and waive any claim that such business opportunity constituted a corporate opportunity that should have been
presented to the Company, the Members or any of their respective Corporate Affiliates, if the Manager or Employed Officer acts in a manner consistent with the following policy: a corporate opportunity presented to any Manager of the Company or an
Employed Officer shall belong to the Designating Member of such Manager or employer of such Employed Officer, unless such opportunity was presented in writing to the Manager or Employed Officer expressly and solely in his or her capacity as a
Manager or officer of the Company, in which event such corporate opportunity shall belong to the Company. If a corporate opportunity that belongs to the Company pursuant to the immediately preceding sentence is not approved as a Company Project, any
Member and any of its Corporate Affiliates may independently pursue such corporate opportunity. 

  

	 	2.9.2	Disclaimer of Certain Duties. Each Member acknowledges its express intent, and agrees with each other Member for the mutual benefit of both the Members, that to the maximum
extent permitted by Applicable Law: 

  

	 	(a)	no Member shall owe any duty of loyalty, under this Agreement, the Act or otherwise, to the Company, to the other Member or any Managers in connection with the exercise of its
voting, consent or approval rights under this Agreement or the granting or withholding of any vote, consent or approval by any Manager appointed by such Member under this Agreement; 

  

	 	(b)	no Manager shall owe any duty of loyalty, under this Agreement, the Act or otherwise, to the Company, to any Member (other than the Designating Member of such Manager) or any other
Manager in connection with the exercise of his or her voting, consent or approval rights under this Agreement; and 

  

 12 

Table of Contents

	 	(c)	the provisions of this Section 2.9.2 shall apply for the benefit of each Member and Manager and no standard of care, duty or other legal restriction or theory of
liability shall limit or modify the right of each Member or Manager to act, and, in the case of each Member, to direct the Managers appointed by such Member to vote in the manner determined by such Member in its sole discretion, other than those
expressly set forth in this Agreement. 

  

	 	2.9.3	Release. To the maximum extent permitted by Applicable Law, each Member (the “Releasing Member”) hereby releases and forever discharges each other Member and
the Managers appointed by the other Member (each, a “Released Party”) from all liabilities that any Released Party might owe, under the Act or otherwise, to the Company, the Releasing Member or the Managers appointed by the
Releasing Member based on (a) any action or omission by such Released Party in its capacity as a member or manager of the Company (other than any fraud or willful misconduct of the Released Party) or (b) on the ground that any decision of
any Released Party to grant or withhold any vote, consent or approval constituted a breach or violation of any standard of care or duty applicable to the Releasing Member or Managers appointed by the Releasing Member. 

  

	 	2.9.4	Covenant Not to Sue. Each Releasing Member hereby irrevocably covenants to refrain from, directly or indirectly, asserting any claim, or commencing, joining in, prosecuting,
participating in, funding any part of, instituting or causing to be commenced, prosecuted, funded or instituted, any suit or other proceeding of any kind against any Released Party based upon any matter released or purported to be released by
Section 2.9.3 above.

Board of Managers may file Articles of amendment to the Articles of Organization or restated Articles of Organization and any other certificates of amendment as may be authorized by the Board of Managers (except any Articles of Dissolution, which
shall require consent in accordance with this Agreement). Any amendments to this Agreement shall be subject to the provisions of Section 24.10. 

  

	2.11	Members; Interest. The name, mailing address and Sharing Percentage of each Member are set forth on Exhibit A hereto. Each Member’s Interest in the Company shall be

	 	3.3.1	Except as otherwise provided in this Agreement, no Member shall be obligated to restore a deficit in the Member’s Capital Account solely by reason of such negative Capital
Account balance. 

  

	 	3.3.2	A transferee of an Interest transferred in accordance with Section 17.2 will succeed to the Capital Account relating to the Member transferring such Interest. However,
if the transfer causes a termination of the Company under Section 708(b)(1)(B) of the Code, the Company shall not dissolve and wind up but shall be continued under the provisions of Reg. §1.708-1(b)(iv) and the Capital Accounts of the
Members shall remain unchanged and shall continue to be maintained in accordance with the principles of this Section 3.3.2. 

  

	 	3.3.3	At such times as may be permitted or required by Regulations issued pursuant to Section 704 of the Code, the Capital Accounts shall be revalued and adjusted to reflect the then
fair market value of Company property and the Capital Accounts shall be maintained to comply with Reg. §1.704-1(b)(2)(iv)(f). All allocations of gain resulting from such revaluation shall be made consistently with that Regulation, and to the
extent not inconsistent therewith, the allocation provisions of Article 7 hereof.

Without limiting the remedies of a non-Defaulting Member, payment of such Capital Contributions shall be one of the Conditions Precedent in Schedule 14.2; provided, however, that only a non-Defaulting Member may waive or exercise any rights under
Section 14.2 for failure of such a Condition Precedent.

Board of Managers (including, with respect to the Initial Project or any Company Project, as necessary in the judgment of the Board of Managers to timely comply with any requirements of the North American Electric Reliability Corporation or
Applicable Law after the In-Service Date), with any such contributions to be made by each Member no later than ten (10) Business Days after the date specified in the applicable Budget or by the Board of Managers, as applicable, in an amount
equal to the applicable capital or operating cash requirements set forth in the applicable Budget or as otherwise approved by the Board of Managers, multiplied by each such Member’s Sharing Percentage.

redistributed pursuant to this Agreement. If the Member fails to contribute such incorrect payment to the Company within thirty (30) days of receiving

determined in a manner consistent with Reg. §1.704-2(g)(2). This Section 7.6.2 is intended to comply with the minimum gain chargeback requirement in Reg. §1.704-2(i)(4) pertaining to Member Non-Recourse Debt and shall be

with respect to the loan to which such Member Loan Non-Recourse Deductions are attributable in accordance with Reg. §1.704-2(i). 

  

	 	7.6.7	Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Company property pursuant to Section 734(b) or Section 743(b) of the Code
is required, pursuant to Reg. §1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of
the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Member(s) in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such
Section of the Regulations.

Table of Contents

	 	 
Article 7 (other than the Regulatory Allocations), the Board of Managers shall make such offsetting special allocations of Tax Items in whatever
manner it determines appropriate so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory
Allocations were not part of this Agreement and all Tax Items were allocated pursuant to Section 7.6. In exercising its discretion under this Section 7.7, the Board of Managers shall take into account future Regulatory
Allocations under Sections 7.6.1 and 7.6.2 that, although not yet made, are likely to offset other Regulatory Allocations previously made under Sections 7.6.5 and 7.6.6. 

  

	7.8	Special Allocation of Gain or Loss on Contributed Property. Under Regulations prescribed by the Secretary of the Treasury pursuant to Section 7.04(c) of the Code, Tax
Items with respect to property contributed to the Company by a Member shall be shared among Members so as to take account of the variation between the basis of the property to the Company and its fair market value at the time of contribution. The
Board of Managers shall make such elections, adopt such conventions, and allocate Tax Items as it deems appropriate to comply with Section 7.04(c) of the Code and any Regulations promulgated thereunder and to preserve, to the extent possible,
uniformity of the Members’ interests in the profits and capital of the Company. Any Tax Items allocated under this Section 7.8 shall not be debited or credited to Capital Accounts to the extent that item is already taken into
account (upon formation or otherwise) in determining a Member’s Capital Account. 

  

	7.9	Change or Transfer of Interests in Profits and Capital. Upon the Transfer of an Interest in the profits and capital of the Company in accordance with
Section 17.2.1, Tax Items attributable to the Transferred Interest shall, for federal income tax purposes, be allocated between the transferor and the transferee of such Interest based on the number of months that each such Person was
the owner of the Interest, in a manner determined by the Board of Managers to be consistent with the requirements of Section 706 of the Code and Regulations or rulings promulgated thereunder. 

  

	7.10	Deemed Income or Gain. If, and to the extent that, any Member is deemed to recognize income or gain as a result of any transaction between the Member and the Company pursuant
to Sections 482, 483, 1272-1274, or 7872 of the Code, or any similar provision now or hereafter in effect, any corresponding resulting loss or deduction of the Company shall be allocated to the Member who was allocated such income or gain.

  

	7.11	Recapture Items. Any portion of any income or gain attributable to the sale or other disposition of any depreciable Company property required to be recaptured as ordinary
income shall, to the maximum extent possible in accordance with Section 704 of the Code and the Regulations thereunder, be allocated among the Members for tax purposes in the same ratio as the deductions giving rise to such recapture were
allocated. Any recapture of tax credit shall be allocated among the Members in accordance with Reg. §1.704-1(b)(4)(ii).

Company; provided, however, that all proposed projects must fall within the scope of the Company’s purposes. A proposal for a project shall include such detail as is reasonably necessary to enable the Board of Managers to evaluate the proposal,
including cost estimates, required regulatory approvals and cost recovery. The Board of Managers shall have forty–five (45) days to accept or reject the proposed project, which acceptance or rejection of which shall be in each
Manager’s sole discretion. A proposed project under this Section 14.3 shall become a “Company Project” only if it unanimously approved as a Company Project by the Board of Managers. If a proposed project becomes a
Company Project, the Members shall appropriately amend this Agreement to provide for such Company Project. The Company shall promptly reimburse each Member for its Qualified Development Expenses following the designation of a project as a Company
Project. 

  

	14.4	Member Rights. In accordance with the provisions of Section 2.9, nothing in this Article 14 is intended to restrict the right of any Member and its
Corporate Affiliates (other than the Company and its subsidiaries) to independently pursue any project, until such time as that project becomes a Company Project. During the term of this Agreement, if any Member identifies any project that it
believes would be suitable for the Company to examine, evaluate, or invest in, such Member shall have, in its sole discretion, the right, but not the obligation, to present such project to the Board of Managers for consideration.

  

	14.5	Right of Members to Pursue the Initial Project. If the Company determines not to pursue the Initial Project, as evidenced by, among other things, (a) dissolution of the
Company, (b) adoption by the Board of Managers of a resolution not to pursue the Initial Project, or (c) written agreement of the Members not to pursue the Initial Project, either Member shall have the right to independently pursue the
Initial Project. Any dispute between the Members with respect to whether the Company has determined not to pursue the Initial Project shall be deemed a Deadlock and resolved in accordance with Section 21 hereof. 

 

	15.	MEMBERS’ INTERNAL COSTS. 

  

	15.1	Pre-Formation Internal Costs. Within one hundred and twenty (120) days following the Effective Date, each Member shall submit to the Company a detailed accounting of its
(including its Corporate Affiliates’) Internal Costs relating to the formation of the Company (the “Pre-Formation Internal Costs”). The Members and their Corporate Affiliates shall be entitled to reimbursement by the Company of
their respective Pre-Formation Internal Costs but only to the extent permitted pursuant to an order from the FERC. 

  

	15.2	Post-Formation Internal Costs. On or before the twentieth (20th) day of each month, each Member shall submit to the Company a detailed accounting of its (including its
Corporate Affiliates’) Internal Costs associated with services performed for or in connection with the Company and the Initial Project (the “Post-Formation Internal Costs”) during the preceding month. The Members and their
Corporate Affiliates shall be entitled to reimbursement by the Company for their Post-Formation Internal Costs but only to the extent provided for in any of Budgets or permitted (i) under the terms of the AEPSC Services Agreement, the Duke
Services Agreement, or any other written agreement approved by the Board of Managers, or (ii) pursuant to an order from the Federal Energy Regulatory Commission.

	17.	ADMISSION OF MEMBERS; TRANSFERS OF INTERESTS; WITHDRAWAL OF A MEMBER. 

  

	17.1	No New Members. No Person shall be permitted to acquire an Interest in the Company from the Company unless mutually agreed by all Members. 

  

	17.2	Transfers of Membership Interests by Members. Except as expressly provided in this Section 17.2, no Member shall be permitted at any time to Transfer, directly or
indirectly, or by operation of law or otherwise, any Interest unless unanimously agreed by all Members. 

  

	 	17.2.1	Transfers to Corporate Affiliates. Any Member may Transfer all or any part of an Interest to one or more of its Corporate Affiliates at any time, provided, however, that such
Corporate Affiliate must be Creditworthy, and such Corporate Affiliate must agree in writing to be bound by the terms and conditions of this Agreement, and provided further that the transferring or assigning Member must pay any Transfer Compensation
Amount owed pursuant to Section 17.4. In the event of a partial Transfer of an Interest, there shall be no increase in the number of Managers and the transferring Member and its transferee shall agree among themselves as to who will
serve as the two (2) Managers to be appointed or designated in accordance with Section 9.2. 

  

	 	17.2.2	Transfers After First Anniversary. At any time after the first anniversary of the In-Service Date of the Initial Project, either Member may Transfer all, but not less than
all, of its Interest in the Company (treating each Member and its Corporate Affiliates as a single entity for this purpose) to a third party, subject to the terms and conditions in this Section 17.2.2.

Table of Contents

	 	(b)	The other Member shall have a right of first refusal to purchase such Interest; provided, however, if such other Member is a Defaulting Member based on a breach described in
Section 18.1.2, such Defaulting Member shall not have a right of first refusal to purchase such interest. The right of first refusal shall be exercised as set forth in Section 17.2.4; and 

  

	 	(c)	The transferring or assigning Member must pay any Transfer Compensation Amount owed pursuant to Section 17.4. 

  

	 	17.2.3	Deemed Dispositions. Any sale, transfer, assignment, pledge, hypothecation, mortgage or other conveyance of all or substantially all of the Ownership Interests in a Member
that owns no substantial assets other than its Interest and any assets directly related thereto shall be deemed a Transfer of its Interest hereunder and must comply with the requirements set forth in this Section 17.2 and, for purposes
of Section 17.2.4, references to a Member’s Interest shall be deemed to be references to such Ownership Interests. For the avoidance of doubt, the sale, transfer, assignment, pledge, hypothecation, mortgage or other conveyance, by
operation of law or otherwise, of all or substantially all of the Ownership Interests in the Ultimate Parent of either Member shall not constitute a Transfer of Interests hereunder or otherwise trigger the requirements set forth in this
Section 17.2. 

  

	 	17.2.4	Right of First Refusal. 

  

	 	(a)	If a Member desires to sell all, but not less than all, of its Interest and has a written offer from a Creditworthy Person (other than a Corporate Affiliate) to purchase such, it
must give written notice to the other Member describing all the material terms of that sale (including the purchase price, the terms for payment, the anticipated closing date, any conditions to the sale, any non-cash consideration and the selling
Member’s estimate of the Fair Market Value of any non-cash consideration), and completely identifying the proposed third party purchaser. The terms of that sale shall not be bundled with or directly or indirectly connected to a transaction
involving assets or securities other than Company assets. 

  

	 	(b)	The written notice delivered pursuant to Section 17.2.4(a) shall be accompanied by a written offer, irrevocable until the later of (i) thirty (30) days from
its receipt or (ii) ten (10) Business Days after determination of the Fair Market Value of any non-cash consideration in accordance with the provisions of this Agreement, to sell to the Member receiving such written notice delivered
pursuant to Section 17.2.4(a) hereof (the “Receiving Member”) all, but not less than all, of the Interest described in the selling Member’s notice on the same terms and conditions as described in the notice, except
that in lieu of any consideration which is other than cash, the Receiving Member will pay cash equal to the Fair Market Value of the consideration, as determined in accordance with the provisions of this Agreement. 

 If the Receiving Member elects to purchase the Interest described in the selling Member’s notice, the Receiving Member shall give the selling Member
written notice that it has elected to accept the offer made to the Receiving Member pursuant to this Section 17.2.4, and the Receiving Member will become bound to purchase, and the selling Member will become bound to sell, the selling
Member’s Interest.

Table of Contents

 The closing of any purchase by the Receiving Member will take place in accordance with the
specifications in the selling Member’s notice, including any specifications concerning regulatory approvals and other conditions. 
 If
the Receiving Member does not accept the offer made to the Receiving Member pursuant to this Section 17.2.4, the proposed sale to the third party may take place on the terms and conditions, including price, specified in the written
notice delivered pursuant to Section 17.2.4(a) hereof. However, the Receiving Member will have the right to examine, within the thirty (30) days following the closing date described in the selling Member’s notice or any later
date on which the sale is consummated, the records of the selling Member and the third party to satisfy itself that the sale has been consummated on the terms described in the selling Member’s notice. If the sale is not consummated on those
terms within one (1) year after the delivery of the selling Member’s notice, or, if later, within thirty (30) days after receipt of all regulatory approvals required in connection with such sale, the Company may cancel on its books
any transfer of Interest previously made to reflect that sale, and the selling Member shall be required to comply with the terms of this Section with respect to any subsequent Transfer of the Interest. 
  

	 	(c)	Each Member acknowledges that: (i) the right of first refusal provided in this Section 17.2.4 is, subject to Section 17.2.2, a material part of the
bargained for consideration under this Agreement, (ii) the inability of a Member to exercise its right of first refusal under this Agreement, except where such Member is a Defaulting Member, would result in a substantial economic detriment to
such Member, and (iii) the exercise of the right of first refusal would not hamper the efforts of any Member seeking to transfer its Interest under this Agreement. Further, each Member acknowledges that the identity of the other Member under
this Agreement at any point in time is a material element of this Agreement bargained for by each party to this Agreement, and it would be a substantial detriment to each such Member if any proposed new Member under this Agreement was not acceptable
to the existing Members. 

  

	 	17.2.5	Interest Pledge. The Members may, with the unanimous approval of the Members, Transfer their Interests or any part thereof in connection with any project or other financing
by the Company of the Initial Project or any other Company Project. Notwithstanding any other provision of Section 17.2, no Transfer of an Interest by a Member in connection with a financing transaction shall be permitted except in
accordance with this Section 17.2.5.

Table of Contents

	 	17.2.6	Prohibited Transfers. Any purported Transfer of any Interests that is not in compliance with this Article 17 shall be null and void and of no force or effect; provided
that if the Company is required to recognize any such Transfer, the Interests Transferred shall be strictly limited to the transferor’s right to allocations and distributions as provided by this Agreement with respect to the Interests
Transferred, which allocations and distributions may be applied (without limiting any other legal or equitable rights of the Company) to satisfy any debts or liabilities for damages that the transferor or transferee may have to the Company, and
shall not include the right to any information or accounting of the affairs of the Company, the right to inspect the books or records of the Company, and/or any of the other rights of a Member under the Act or this Agreement.

  

	 	17.2.7	Compliance with Securities Laws. If any Interests are to be Transferred, either (a) such Interests shall be registered under the Securities Act of 1933, as amended, and
any applicable state securities laws, or (b) at the request of the Board of Managers, the transferor shall provide an opinion of counsel, satisfactory to the Board of Managers, that the proposed Transfer is exempt from such registration
requirements. The Company and the Members have no obligation or intention whatsoever either to register Interests for resale under any federal or state securities laws or to take any action which would make available to any Person any exemption from
the registration requirements of such laws. 

  

	17.3	Withdrawal of a Member. No Member may withdraw from membership in the Company prior to the dissolution and winding up of the Company. 

  

	17.4	Transfer Compensation Amount. If a Member Transfers its Interest to a Corporate Affiliate pursuant to Section 17.2.1 or to a third party pursuant to
Section 17.2.2, and if such Transfer results in a termination of the tax partnership pursuant to Section 708(b)(1)(B) of the Code, then the Member transferring its Interest shall pay the Member who is not transferring its Interest a
cash amount equal to the excess of (a) the present value of the depreciation and amortization deductions that the non-transferring Member would have received with respect to the assets owned by the Company on the Transfer date if such transfer
had not occurred over (b) the present value of such deductions after giving effect to Section 168(i)(7) of the Code, which has the effect of restarting the depreciation or amortization period for such assets (such amount the
“Transfer Compensation Amount”). “Present value” for purposes of the preceding sentence shall be determined (i) by using as the discount rate the prime rate as published by The Wall Street Journal for the date
of the Transfer, (ii) by using as the tax rate the highest federal and Oklahoma combined corporate income tax rate in effect on the date of the transfer, and (iii) by assuming that the Company will depreciate or amortize all of the assets
that it owns on the Transfer date over their entire tax lives. The non-transferring Member shall calculate the Transfer Compensation Amount and make written demand for its payment on the transferring Member, who shall pay such amount within ten
(10) Business Days of receipt of such demand. The Members shall submit any dispute over the operation of this Section 17.4 to the Arbitrator for resolution. A Member Transferring its Interest pursuant to Section 17.2.1
or 17.2.2 may effect such Transfer in a series of transactions for the purpose of avoiding a termination of the tax partnership; provided, however, that such series results in the Transfer of such Member’s entire interest within a period
that does not exceed thirteen (13) calendar months. This Section 17.4 shall not apply to any Transfer pursuant to Section 17.2.4.

Interest at a price equal to the Defaulting Member’s Capital Account balance, as adjusted in accordance with Section 18.2.2(b), on the date the Defaulting Member’s Interest is transferred to the non-Defaulting Member less

Member’s Event of Default and ends on the day immediately preceding the day on which the Defaulting Member’s Interest is transferred to the non-Defaulting Member (the “Interim Period”), (i) all losses of the Company,

Table of Contents

	 	 
GAAP, shall be allocated 50% to the Defaulting Member’s Capital Account and 50% to the non-Defaulting Member’s Capital Account and (ii) all
profits of the Company shall be determined monthly, in accordance with GAAP, as of the last day of each month during the Interim Period and such profits shall be allocated to each Member’s Capital Account based on the percentage that each
Member’s Capital Account is of the combined balance of the Members’ Capital Accounts as of the last day of each month during the Interim Period. 

  

	 	(c)	There shall be no distributions of Available Cash to the Members during the Interim Period if the In-Service Date has not occurred. If the In-Service Date has occurred, Available

Third-Party Approvals so long as the non-Defaulting Member is diligently pursuing obtaining any such Third-Party Approvals. 

  

	 	(e)	At the closing of the transfer of the Defaulting Member’s Interest to the non-Defaulting Member, the Defaulting Member shall (i) sign such documents as may reasonably be
requested by the non-Defaulting Member in order to consummate the transfer, (ii) represent and warrant that (A) it has good title to its Interest, (B) there are no Encumbrances on such Interest (other than pursuant to this Agreement

pending or threatened litigation or other Proceeding required to be disclosed herein or the non-Defaulting Member reasonably determines that any representation or warranty required by clause (ii) herein is inaccurate, the non-Defaulting Member
may, in its sole discretion, withdraw its election to purchase the Defaulting Member’s Interest and pursue any other remedies that are available to it under this Agreement. 

  

	 	18.2.3	The provisions of Section 18.2.2 shall not be applicable to an Event of Default that results from a Member’s breach of the confidentiality obligations contained in
Section 22 unless such Member’s breach is an intentional breach. 

  

 36 

Table of Contents

	 	18.2.4	If the Event of Default is described in Section 18.1.2, in addition to having the remedies provided in Section 18.2.2, but in lieu of an action by the
Company to pursue any remedies for such Event of Default: 

  

	 	(a)	The non-Defaulting Member shall have the right, but not the obligation, to elect, in its sole discretion at any time after the Event of Default, but subject to obtaining required
Third-Party Approvals, to deliver to the Company within sixty (60) days after occurrence of the Event of Default, all, but not less than all, of the capital contribution which the Defaulting Member has failed to contribute (the “Failed
Contribution”). The amount shall be treated as payment of the Failed Contribution by the non-Defaulting Member and the non-Defaulting Member’s Capital Account shall be increased accordingly. In addition, the non-Defaulting
Member’s Interest and Sharing Percentage shall be increased (and the Defaulting Member’s Interest and Sharing Percentage shall be correspondingly decreased) by an amount equal to twice the percentage increase in the non-Defaulting
Member’s Capital Account that occurs as a result of the non-Defaulting Member’s payment of the Failed Contribution. 

  

	 	(b)	Additionally, upon notice to the Defaulting Member, the non-Defaulting Member may prohibit the Defaulting Member from making any subsequent Capital Contributions in which case the
non-Defaulting Member shall be required to make such Capital Contributions on behalf of the Defaulting Member. In each instance that the non-Defaulting Member makes a subsequent Capital Contribution on behalf of the Defaulting Member, the amount
shall be treated as payment of a Capital Contribution by the non-Defaulting Member and the non-Defaulting Member’s Capital Account shall be increased accordingly. In addition, the non-Defaulting Member’s Interest and Sharing Percentage
shall be increased (and the Defaulting Member’s Interest and Sharing Percentage shall be correspondingly decreased) by an amount equal to twice the percentage increase in the non-Defaulting Member’s Capital Account that occurs as a result
of the non-Defaulting Member’s payment of the Capital Contribution; provided, however, that in no event shall the Defaulting Member’s Sharing Percentage be less than 1%. Notwithstanding anything to the contrary set forth in this Agreement,
neither the Company nor the non-Defaulting Member shall be required to provide any advance notice to the Defaulting Member of any Capital Contribution made pursuant to this Section 18.2.4(b); provided that the Company shall provide the
Defaulting Member with written notice of each adjustment of the Members’ Capital Accounts, Interests and Sharing Percentages as a result of Capital Contributions by the non-Defaulting Member pursuant to this Section 18.2.4(b).

Member set forth in this Section 18.2.5 at least sixty (60) days prior to such Transfer. The Drag-Along Notice will set forth the name of the Buyer, the proposed amount and form of consideration, and the other material terms and
conditions of the proposed transfer. In connection with any such Transfer, the Defaulting Party shall be obligated to (i) make representations and warranties (and provide related indemnities) with respect to its ownership of its Interest,
(ii) agree to pay its proportionate share of any liability arising out of any representations, warranties, covenants or agreements of the Members with respect to the Company that survive the closing of the Sale and (iii) execute and
deliver such instruments of conveyance, purchase agreement, merger agreement, escrow agreements and/or related documents and take such other actions as the non-Defaulting Member or the Buyer may reasonably require in order to carry out the Sale and
the terms of this Section 18.2.5 and. The terms of the Sale shall not be bundled with or directly or indirectly connected to a transaction involving assets or securities other than the Company’s assets. 

 

	 	18.2.6	With respect to any Proceedings that result from or are required in connection with the non-Defaulting Member’s exercise of any of the remedies provided for herein, the

indirectly, such Proceedings. 

  

	 	18.2.7	The exercise of any of the remedies set forth in this Section 18.2 shall be in all cases subject to receipt of all necessary Third Party Approvals. The non-Defaulting

heirs, executors, successors and assigns of each of the foregoing (individually an “Indemnitee”) from and against all Damages to the extent caused by, resulting from or arising out of or in connection with any of the following:

  

	 	(a)	any claim, action, suit or proceeding or threat thereof, made or instituted in which such Member, such Member’s Corporate Affiliates or Indemnitee may be involved or be made a
party by reason of such Member being, or having been in the past, a Member, or by reason of any action alleged to have been taken or omitted by such Member in such capacity, or by such Member’s Corporate Affiliates or Indemnitees acting on
behalf of the Company, provided that a Member, Member’s Corporate Affiliate or Indemnitee shall only be entitled to indemnification hereunder to the extent such Member’s, Member’s Corporate Affiliate’s or Indemnitee’s
conduct did not constitute bad faith, willful misconduct, gross negligence or a material breach of this Agreement. The termination of any proceeding by settlement, judgment, order, conviction or upon a plea of nolo contendere or its equivalent shall
not, of itself, create a presumption that such Member’s, Member’s Corporate Affiliate’s or Indemnitee’s conduct constituted bad faith, willful misconduct, gross negligence or a material breach of this Agreement, by such Member,
such Member’s Corporate Affiliate or such Indemnitee; 

  

	 	(b)	any guarantees or promises of performance of any obligations of the Company; and

Other Indemnified Person or Indemnitee (in any case the “Indemnified Party”) from any claim, suit, action or proceeding brought by any other person or entity (a “Third Party Claim”), the Indemnified Party shall give
notice as promptly as is reasonably practicable to the Indemnifying Party of such Third Party Claim; provided that the failure of the Indemnified Party to give notice shall not relieve the Indemnifying Party of its obligations under this Article
18 except to the extent (if any) that the Indemnifying Party shall have been materially prejudiced thereby. Such Indemnifying Member or the Company, as the case may be, will have the right to control the defense and settlement of such Third
Party Claim with counsel reasonably acceptable to the Indemnified Party, provided that (i) such Indemnified Party may retain counsel at its expense to assist in the defense and settlement of such Third Party Claim, and (ii) no settlement
of any Third Party Claim will contain terms or provisions requiring the Indemnified Party to take any action or perform any undertaking, or prohibit or restrain the Indemnified Party from taking any action, without the written consent of the
Indemnified Party.

	18.5	Winding Up. Upon the dissolution of the Company, the Company shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets,
and satisfying the claims of its creditors and Members. No Member shall take any action with respect to the Company that is inconsistent with, or not necessary to or appropriate for, the winding up of the Company’s business and affairs. Each

refer such Deadlock to the Presidents of AEPTHC and Duke or their designees. Such Deadlock Notice shall describe in reasonable detail the nature of the Deadlock. Each Member shall cause the individual it designates to resolve the Deadlock promptly
to consult and negotiate in good faith with the individual designated by the other Member in an effort to resolve such Deadlock. 

  

 43 

Table of Contents

	 	21.1.2	If the individuals designated to resolve a Deadlock pursuant to Section 21.1.1 are unable to resolve such Deadlock within twenty (20) days of delivery of the
Deadlock Notice, a Member may commence an arbitration pursuant to Section 21.2 (a “Deadlock Arbitration”) by delivering written notice to the other Member stating its intent to commence such Deadlock Arbitration.

  

	 	21.1.3	Without limiting any rights or remedies that may otherwise be available to the Members pursuant to this Agreement or the Act, the procedures set forth in this Article 21
shall constitute the exclusive remedy to resolve a Deadlock. 

  

	21.2	Deadlock Arbitration. 

  

	 	21.2.1	No later than ten (10) days after issuance of a written notice to commence a Deadlock Arbitration pursuant to Section 21.1.2, each Deadlock Arbitration Party shall
prepare and deliver to each other Deadlock Arbitration Party a written statement (an “Issues Statement”) of each issue that such Deadlock Arbitration Party believes constitutes a Deadlock. No later than twenty (20) days after
the deadline for delivery of Issue Statements, each Deadlock Arbitration Party shall deliver to each other Deadlock Arbitration Party a written statement (a “Settlement Proposal”) of such Deadlock Arbitration Party’s proposed
resolution of the Deadlock, which shall be limited to the issues set forth in the Issues Statements. A Settlement Proposal need not address every issue described in every Issues Statement. If a Deadlock Arbitration Party fails to deliver a
Settlement Proposal within such period, such Deadlock Arbitration Party shall be deemed to have waived its rights to submit a Settlement Proposal. 

  

	 	21.2.2	The Deadlock Arbitration Parties shall attempt in good faith to resolve the Deadlock that is the subject of the Deadlock Arbitration based on the positions set forth in the
Settlement Proposals. If the Deadlock Arbitration Parties are unable to resolve such Deadlock within twenty (20) days after the deadline for delivery of Settlement Proposals (or such longer period as may be agreed among the Members), each
Deadlock Arbitration Party shall submit the name of a Qualified Person in writing to each other Deadlock Arbitration Party. Any Deadlock Arbitration Party that fails to submit the name of a Qualified Person within such period shall be deemed to have
waived its right to designate a Qualified Person. 

  

	 	21.2.3	All of the Qualified Persons designated by the Deadlock Arbitration Parties pursuant to Section 21.1.2 shall, within ten (10) days of their designation (or such
longer period as may be agreed among the Deadlock Arbitration Parties), select a single Qualified Person (the “Deadlock Arbitrator”) to resolve the Deadlock; provided, however, that if only one Deadlock Arbitration Party designates
a Qualified Person or if all Deadlock Arbitration Parties submitting names of Qualified Persons submit the name of the same Qualified Person, such Qualified Person shall serve as the Deadlock Arbitrator. The Qualified Persons shall notify each
Deadlock Arbitration Party of the name of the Deadlock Arbitrator promptly upon designation of such Deadlock Arbitrator. 

  

 44 

Table of Contents

	 	21.2.4	No later than three (3) days (or such longer period as may be agreed among the Deadlock Arbitration Parties) after the Deadlock Arbitrator is selected, each Deadlock
Arbitration Party shall deliver a copy of its Settlement Proposal to the Deadlock Arbitrator. 

  

	 	21.2.5	The Deadlock Arbitrator shall review the Settlement Proposals and, after due consideration thereof, the Deadlock Arbitrator shall select the one Settlement Proposal that, in the
Deadlock Arbitrator’s reasoned judgment, best resolves the Deadlock on a basis that is consistent with the terms of this Agreement; provided, however, that the Deadlock Arbitrator may not alter or add to the terms of any Settlement Proposal in
reaching its determination. A Deadlock Arbitrator’s decision pursuant to this Section 21.2.5 shall be final and binding on the Company and the Members with respect to the Deadlock. 

  

	 	21.2.6	No Member or any of its Corporate Affiliates, nor any of their respective employees, agents, counsel, consultants or other representatives, shall be permitted to have any ex parte
communications with the Deadlock Arbitrator. The Deadlock Arbitrator shall be advised of this restriction and shall be instructed by the Deadlock Arbitration Parties to notify all Deadlock Arbitration Parties of any such attempted ex parte
communications. 

  

	 	21.2.7	Each Deadlock Arbitration Party shall pay the fees and expenses of the Qualified Person selected by it. The Deadlock Arbitration Parties shall equally share the fees and expenses of
the Deadlock Arbitrator.

Representatives directly or indirectly from the disclosing party, or (d) is independently developed by Representatives of the recipient without access to Confidential Information.

transmitted is required pursuant to Applicable Law or otherwise becomes legally compelled to disclose any of the Confidential Information or the fact that the Confidential Information has been made available to it, such party shall (unless
prohibited by Applicable Law from doing so) promptly advise the disclosing party in order that the disclosing party may seek a protective order or such other remedy as the disclosing party may consider appropriate in the circumstances. In any event,
the compelled party may disclose only that portion of the Confidential Information which such party is legally required to disclose in the judgment of the party’s legal counsel without any liability to the disclosing party hereunder and such
disclosure shall not be a breach of this Section 22.4.

 59Amended and Restated Master Service Agreement with Virtusa Corporation

 Exhibit 10.50 
 Amendment No. 3 to Amended and Restated Master Services Agreement 
 This Amendment NO.3 to (the
“Transition Amendment”) to the Amended and Restated Master Services Agreement between Virtusa Corporation (“Virtusa”) and Vignette Corporation (“Vignette”) dated as of November 1, 2005, including Attachment 1
thereto, each as amended (the “Agreement”) is entered into this 27 day of August, 2008 (“Effective Date”). 
 WHEREAS Vignette and
Virtusa have agreed to amend the Agreement on the terms set forth herein; 
 NOW THEREFORE, in consideration of the mutual promises set forth in this
Transition Amendment, the parties agree as follows: 
 1. All defined terms, unless otherwise defined in this Transition Amendment, shall have the meanings
given them in the Agreement. 
 2. Vignette hereby provides written notice of termination of the Agreement under Section 8.1(B) of the Agreement as
Termination For Convenience, subject to the terms herein. The Agreement will terminate on August 13, 2009 (The “Termination Date”). 
 3.
Provided that Vignette complies with all of its obligations under this Transition Amendment and the Agreement, and all payments of outstanding invoices as of the date of Transition Amendment arc paid in full, the Minimum Termination Fee is hereby
reduced to One Million Dollars ($1,000,000). The Minimum Termination Fee is payable as follows: 
 (i) Five hundred thousand dollars
($500,000) shall be due and payable on the Effective Date (“Initial Termination For Convenience Fee”); such obligation and payment is non-cancelable and non-refundable; 
 (ii) Five hundred thousand dollars ($500,000) shall be due and payable 90 days from the date of the Effective Date (“Final Termination For
Convenience Fee”); when paid, such payment shall be non-cancelable and non-refundable. 
 4. Vignette shall engage and maintain on a full time basis the
following number of Virtusa GDC Resources for the following time periods, at the rates as set forth in the Agreement: 
  

	 	(i)	At least 125 Virtusa GDC Resources on a full time basis for 166 days from the payment of the initial Termination For Convenience Fee set forth in Section 3(i) above
(“Commitment 1” and the period is the “Commitment 1 Period”); 

  

	 	(ii)	At least 75 Virtusa GDC Resources on a full time basis for 90 days following the Commitment 1 Period (“Commitment 2” and the period is the “Commitment 2
Period”); 

  

	 	(iii)	At least 40 Virtusa GDC Resources on a full time basis for 90 days following the Commitment 2 Period. 

 Although the number of Virtusa GDC Resources will be gradually reduced on the timetable set forth above, the daily rates paid by Vignette for such Resources will be calculated as per the terms of the Agreement, except
that after the end of the Commitment 1 Period, the Fixed Cost component of the rates in the Agreement shall be fixed at $25.20 and after October 1 2008, the “Variable Other” component shall be fixed at $118.33. 
  

 1 

 In the event that attrition reduces the GDC Resources below the minimum levels set forth in this section, and Virtusa
fails to provide Vignette the number of resumes for such applicable positions per the terms and conditions of the Agreement so as to cause a failure to comply with the applicable service levels, the minimum GDC Resource Commitments shall be reduced
with respect to such position, but only for so long as Virtusa to fulfill its service requirement for such position. Upon fulfillment of the service requirement for such position, the GDC Resource Commitment shall be increased accordingly.

 Each time period under (i), (ii) and (iii) is referred to as a Commitment Period. 
 For the avoidance of doubt, provided that Vignette complies with all of its obligations under this Transition Amendment and the Agreement, 
  

	 	(a)	the above resource and notice requirements in this Section 4 only modifies the Minimum Team Commitment and 180 day written notice period for Termination For Convenience under
Section 8.1(B) of the Agreement; and 

  

	 	(b)	provided that Vignette complies with its Commitment in each Commitment Period, Vignette may have flexibility in satisfying its Commitment for such period. For instance, under
Commitment 2, if Vignette had 85 full time Virtusa GDC Resources in month 1, 75 in month 2 and 65 in month 3 of that Commitment Period, Vignette would satisfy the requirement, (i.e., the average number of minimum billable days in each month of the
Commitment Period equals or exceeds that of 75 Virtusa GDC Resources engaged in each month of the Commitment Period); and 

  

	 	(c)	all other notice provisions in the Agreement apply, including without limitation, those in Section 1 .3 therein. 

 5. Upon payment by Vignette, and receipt by Virtusa, in liquid funds of the Initial Termination For Convenience Fee, and continued compliance by Vignette of its
obligations hereunder, 
  

	 	a.	With respect to each Virtusa Special Employee as of Effective Date, Vignette shall have the Transfer Right with respect to such employee for the period of 75 days from
Virtusa’s receipt of the Initial Termination For Convenience Fee (the “Solicitation Period”); 

  

	 	b.	With respect to each new hire that becomes a Virtusa Special Employee after the Effective Date but before the Termination Date, Vignette shall have the Transfer Right for such
employee for the period of 75 days from the date of hire (“New Employee Solicitation Period”); 

 For new hires and those other
Virtusa Special Employees otherwise under probation; provided that such employees become a Virtusa Special Employee after the Effective Date but before the Termination Date, the Solicitation Period and/or the New Employee Solicitation Period as
applicable will not begin for such employees until 75 days after the date of hire. 
  

	 	c.	For the GDC Resources who are on long leave of absence (the “Long Leave Employee”), the solicitation period will not begin until such employees return from such leave of
absence but shall be 75 days from the date the employee returns from leave; provided that such employee is a Virtusa Special Employee at 

  

 2 

	 	 
time of solicitation; and provided further that Exhibit A hereto sets forth all employees who are on long leaves of absence as of the time of the
Effective Date. No other employees shall he deemed a Long Leave Employee. 

 Vignette shall not have the right to alter the current
appraisal cycles and schedules as set forth in the Agreement. However, to the extent that any GDC Resource who accepts an offer from Vignette, and after such acceptance, such employee undergoes a performance review process in ordinary course and is
subject to a promotion or compensation increase, Virtusa will not increase the employee’s compensation or promote such employee without the prior written consent of Vignette. 
 6. Regardless of the terms of the Agreement, no other notice under the Agreement is required to effect the solicitation period and transfer rights, and Vignette shall have the right, after payment of the Initial
Termination For Convenience Fee and receipt by Virtusa of such fee and all outstanding payments due under the Agreement per the Agreement, to immediately contact all Virtusa Special Employees, inform them of the full details of the plan and to
provide all Virtusa Special Employees (at Vignette’s option) with an Offer Letter. The Offer Letter must contain at a minimum, a binding offer of employment, with applicable details, including estimated compensation, and title, and such other
terms as is required to make the Offer Letter binding under Indian law. Upon acceptance of the Offer Letter by such employee in writing within the applicable solicitation period, such employee must provide a resignation letter to Virtusa with a
resignation date coinciding with the date of hire by Vignette for such Offer Letter to be effective hereunder. Since the actual date of hire may not be known to Vignette as of the acceptance of the Offer Letter, Vignette may provide a range of start
dates and set the firm hire date in a subsequent correspondence with the employee. The resignation letter will state that the resignation is effective as of the actual hire date by Vignette, but need not specify the specific date. For the avoidance
of doubt, all accepted Offer Letters must be executed by Vignette and the employee during the applicable solicitation period. Further, the accompanying resignation letters, and evidence of the fully executed Offer Letters must be provided to Virtusa
within the applicable solicitation period to be effective for purposes hereunder. The form and content (with the exclusion of actual compensation details) of Offer Letter and resignation letter shall be mutually agreed to in writing by the parties
prior to use and no changes shall be permissible without the prior written consent of the other party hereto. Approval of the Offer Letter and resignation letter shall not be unreasonably withheld. 
 7. Not in limitation of either party’s obligations under Section 10.4(b) of the Agreement Virtusa’s obligations thereunder shall commence with respect to
any Virtusa Special Employee during the applicable solicitation period hereunder, and if such Virtusa Special Employee accepts in writing the Offer Letter from Vignette during the applicable solicitation period, Virtusa’s obligations under
Section 10.4(b) shall continue to apply for such Virtusa Special Employee from the date that such Virtusa Special Employee accepts the Offer Letter in writing for the term as stated in Section 10.4(b) of the Agreement (i.e., 12 months
after termination of the Agreement). 
  

 3 

 Virtusa agrees to follow the terms of the Agreement, including all necessary assistance to Vignette until
the Termination Date including delivering paperwork and to pay bonuses approved by Vignette, subject to the terms of the Agreement. 
 The
term “Transfer Right Term” as used in the Agreement is hereby deleted and replaced with the terms, Phase I Initial Solicitation Period and Phase 1 New GDC Solicitation Period, as applicable. 
 8. With respect to any Virtusa Special Employee who accepts in writing an Offer Letter from Vignette within the applicable solicitation period (a “GDC –
Vignette Employee”) under the terms herein, and provided that Vignette continues to comply with its obligations hereunder, Vignette shall have the right to move each such GDC-Vignette Employee to Vignette facilities on 15 days’ prior
written notice to Virtusa only after such employee has formally become an employee of Vignette (i.e., is on Vignette payroll) and has terminated employment with Virtusa; provided that (a) Vignette shall provide written proof of offer acceptance
prior to such move and (b) Vignette shall still be obligated to pay the applicable billing fees for each such GDC-Vignette Employee (if any, for any minimum commitment hereunder) after the move for the applicable Commitment Period as set forth
in Section 4 above and the Agreement. 
 9. All Virtusa Special Employees who elect to not accept employment offers from Vignette must remain as part of
the GDC and work at Virtusa’s facilities until the termination of the Agreement, subject to the current rotation and other applicable policies in the Agreement. 
 10. Notwithstanding anything in the contrary in the Agreement, including Section 2 of Attachment 2 of the Agreement, during the applicable solicitation periods, Virtusa shall be expressly permitted to communicate
to each Virtusa Special Employee the following, and the following shall not be deemed a violation of the Agreement or this Transition Amendment: 
 a. Virtusa values all its GDC Employees; 
 b. All Virtusa Special Employees may remain an employee of Virtusa if he/she does not
accept employment with Vignette; 
 c. However, details of any position and compensation can only take place until after the applicable
solicitation period has expired and only if such employee chooses not to accept the Vignette Offer Letter within the applicable solicitation period. Notwithstanding the foregoing, if the Virtusa Special Employee rejects the offer of employment from
Vignette and does not accept an offer from Vignette by the expiration of the applicable solicitation period, no further restrictions apply under the Agreement or this Transition Amendment regarding the career- pathing, hiring, soliciting,
compensation, communications or continued employment of such Virtusa Special Employee by Virtusa, provided that any changes in position or salary must follow the normal Virtusa appraisal cycles until the Termination Date. 
 11. All other terms of the Agreement remain unchanged, including without limitation, Virtusa’s obligations to provide recruiting services and to meet the SLAs under
the Agreement and the non-solicitation provisions. In the event of any express conflict between the Agreement and this Transition Amendment, the terms of this Transition Amendment shall govern.
