(a) First, to the General Partner until the General Partner has been allocated an amount equal to the excess, if any, of (i) the absolute
value of cumulative Losses allocated to the General Partner pursuant to Section 7.2(b) for all prior Fiscal Years, over (ii) the cumulative amount of Profits allocated to the General Partner pursuant this Section 7.1(a) for all prior
Fiscal Years; 
 (b) Second, to the Limited Partners in proportion to, and to the extent of, an amount equal to the excess, if any, of

Section 7.1(b) for all prior Fiscal Years; and 
 (c) Third, to the Limited Partners accordance with their Percentage Interests. 

Section 7.2 Losses. After giving effect to the special allocations set forth in Section 7.3, and Section 7.4, and except
as provided in Section 10.2(b), all Losses from operations for each Fiscal Year (or part thereof) shall be allocated to the Partners in the following order and priority:

 (b) Second, to the
General Partner. 
 To the extent Losses allocated to a Limited Partner would cause such Limited Partner to have an Adjusted Capital Account Deficit at the
end of any Fiscal Year, the Losses will be reallocated to the other Limited Partners to the extent such reallocation will not cause any such Limited Partner to have an Adjusted Capital Account Deficit. If any Limited Partner receives an allocation
of 

  
 9 








 
Losses otherwise allocable to another Limited Partner pursuant to this provision, such Limited Partner shall be allocated Profits in subsequent Fiscal Years necessary to reverse the effect of
such reallocation of Losses and such allocation of Profits (if any) shall be made before any other Profit allocations under Section 7.1. 

Section 7.3 Special Allocations. The following special allocations shall be made in the following order: 

(a) Minimum Gain Chargeback. Except as otherwise provided in Treasury Regulations
Section 1.704-2(f), notwithstanding any other provision of this Article 7, if there is a net decrease in Partnership Minimum Gain during any Fiscal Year, each Partner will be allocated items of
Partnership income and gain for the Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to the Partner’s share of the net decrease in Partnership Minimum Gain, determined in accordance with Treasury Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence will be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated
shall be determined in accordance with Treasury Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 7.3(a) is intended to comply with the
minimum gain chargeback requirement in Treasury Regulations Section 1.704-2(f) and will be interpreted consistently therewith. 

(b) Partner Minimum Gain Chargeback. Except as otherwise provided in Treasury Regulations
Section 1.704-2(i)(4), notwithstanding any other provision of this Article 7, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any
Fiscal Year, each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain attributable to that Partner Nonrecourse Debt, determined in accordance with Treasury Regulations
Section 1.704-2(i)(5), will be allocated items of Partnership income and gain for the Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to the Partner’s share of the net
decrease in Partner Nonrecourse Debt Minimum Gain attributable to the Partner Nonrecourse Debt, determined in accordance with Treasury Regulations Section 1.704-2(i)(4). Allocations pursuant to the
previous sentence will be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated will be determined in accordance with Treasury Regulations
Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 7.3(b) is intended to comply with the minimum gain chargeback requirement in Treasury Regulations Section 1.704-2(i)(4) and will be interpreted consistently therewith. 
 (c) Qualified Income
Offset. In the event that any Partner unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4),
1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain will be allocated to the Partner in an amount and manner sufficient to
eliminate, to the extent required by the Treasury Regulations, the Adjusted Capital Account Deficit of the Partner as quickly as possible; provided that an allocation pursuant to this Section 7.2(c) will be made only if and to the extent
that the Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 7 have been tentatively made as if this Section 7.3(c) were not in this Agreement. 

  
 10 








 (d) Gross Income Allocation. In the event that any Partner has an Adjusted Capital Account
Deficit at the end of any Fiscal Year, each such Partner shall be allocated items of Partnership income and gain in the amount of the deficit as quickly as possible; provided that an allocation pursuant to this Section 7.3(d) will be
made only if and to the extent that the Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 7 have been tentatively made as if Section 7.3(c) and this Section 7.3(d) were not
in this Agreement. 
 (e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall be allocated to the Partners in
accordance each Partner’s Percentage Interest. 
 (f) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions for any

 (g) Section 754 Adjustments. To the extent an adjustment to the
adjusted tax basis of any Partnership asset, pursuant to Code Section 734(b) (including pursuant to Treasury Regulations Section 1.734-2(b)(1)) is required, pursuant to Treasury Regulations
Section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Partner in
complete liquidation of the Partner’s interest in the Partnership, the amount of the adjustment to Capital Accounts will be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases the
basis) and the gain or loss will be allocated to the Partners in proportion to their interests in the Partnership in the event Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the
Partner to whom the distribution was made in the event Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies. 

Section 7.4 Regulatory Allocations. The allocations set forth in Section 7.3 (the “Regulatory
Allocations”) are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the Partners that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory
Allocations or with special allocations of other items of Partnership income, gain, loss or deduction pursuant to this Section 7.4. Therefore, notwithstanding any other provision of this Article 7 (other than the Regulatory Allocations), but
subject to the Code and the Treasury Regulations, the General Partner shall make such offsetting special allocations of Partnership income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting
allocations are made, each Partner’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not part of this Agreement. In making such
determination, the General Partner shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made. 

Section 7.5 Income Tax Allocations. 

(a) Except as provided in this Section 7.5, each item of income, gain, loss and deduction of the Partnership for federal income tax
purposes shall be allocated among the Partners in the same manner as such items are allocated for book purposes under Section 7.1, Section 7.2, Section 7.3, Section 7.4, and
Section 10.2(b). 

  
 11 








 (b) In accordance with Code Section 704(c) and the applicable Treasury Regulations
thereunder, income, gain, loss and deduction with respect to any property contributed to the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such
property to the Partnership for federal income tax purposes and its Gross Asset Value at the time of its contribution to the Partnership. If the Gross Asset Value of any Partnership property is adjusted in accordance with clause (b) or
(d) of the definition of Gross Asset Value, then subsequent allocations of income, gain, loss and deduction shall take into account any variation between the adjusted basis of such property for federal income tax purposes and its Gross Asset
Value as provided in Code Section 704(c) and the related Treasury Regulations. For purposes of such allocations, the Partnership shall elect the remedial allocation method described in Treasury Regulation Section 1.704-3(d). 

(c) All items of income, gain, loss, deduction and credit allocated to the Partners in accordance with the provisions hereof and basis
allocations recognized by the Partnership for federal income tax purposes shall be determined without regard to any election under Section 754 of the Code which may be made by the Partnership. 

(d) If any deductions for depreciation or cost recovery are recaptured as ordinary income upon the Transfer of Partnership properties, the
ordinary income character of the gain from such Transfer shall be allocated among the Partners in the same ratio as the deductions giving rise to such ordinary character were allocated. 

Section 7.6 Allocation and Other Rules.

ARTICLE VIII 

MANAGEMENT AND OPERATIONS OF BUSINESS 

Section 8.1 General Partner’s Authority; Reimbursement. Except as otherwise expressly provided in this Agreement, all powers
to control and manage the business and affairs of the Partnership shall be vested exclusively in the General Partner; and the Limited Partners shall not have any power to control or manage the Partnership. The General Partner shall be reimbursed on
a basis as the General Partner may determine for (a) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership (including salary, bonus, incentive compensation and other amounts paid to any Person, including
Affiliates of the General Partner, to perform services for the Partnership or for the General Partner in the discharge of its duties to the Partnership) and (b) all other direct and indirect expenses allocable to the Partnership or otherwise
incurred by the General Partner in connection with operating the Partnership’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the
Partnership. Reimbursements pursuant to this Section 8.1 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 8.3. The General Partner may be removed or replaced
only with the written consent of the General Partner and Limited Partners having at least 95% of the Percentage Interests. 

Section 8.2 Approval Required for Certain Action. In addition to matters set forth in Section 6.1, the General Partner
shall not cause the Partnership to, and the Partnership shall not, take any of the following actions without the approval or consent of the Limited Partners (which consent may be made categorically or by policy): 

(a) effecting any merger or consolidation involving the Partnership; 

(b) effecting any sale or exchange of all or substantially all of Partnership’s assets; 

(c) dissolving or liquidating the Partnership; 

(d) creating or causing to exist any consensual restriction on the ability of the Partnership or its subsidiaries to make distributions, pay
any indebtedness, make loans or advances or transfer assets to its Limited Partners or their subsidiaries; 
 (e) settling or compromising
any claim, dispute or litigation directly against, or otherwise relating to indemnification by the Partnership of, any of the directors or officers of the General Partner; or 

(f) issuing additional interests in the Partnership. 

  
 13 








 Section 8.3 Indemnification. 

(a) To the fullest extent permitted by law, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and
all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed claims, demands,
actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by
reason of its status as an Indemnitee and acting (or refraining to act) in such capacity; provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of
competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 8.3, the Indemnitee acted in Bad Faith or, in the case of a criminal matter, acted with
knowledge that the Indemnitee’s conduct was unlawful. Any indemnification pursuant to this Section 8.3 shall be made only out of the assets of the Partnership, it being agreed that the Partners shall not be personally liable for
such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification. 

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant
to Section 8.3(a) in appearing at, participating in or defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a final and non-appealable judgment entered by a court of
competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 8.3, that the Indemnitee is not entitled to be indemnified upon receipt by the Partnership of
any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 8.3. 

(c) The indemnification provided by this Section 8.3 shall be in addition to any other rights to which an Indemnitee may be
entitled under any agreement, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve
in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee. 
 (d) The
Partnership may purchase and maintain (or reimburse any Partner or its Affiliates for the cost of) insurance, on behalf of any Partner, its Affiliates, the Indemnitees and such other Persons as the General Partner shall determine, against any
liability that may be asserted against, or expense that may be incurred by, such Person in connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would
have the power to indemnify such Person against such liability under the provisions of this Agreement. 
 (e) For purposes of this
Section 8.3, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves


  
 14 








 
services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall
constitute “fines” within the meaning of Section 8.3(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best
interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Partnership. 

(f) In no event may an Indemnitee subject any of the Partners to personal liability by reason of the indemnification provisions set forth in
this Agreement. 
 (g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 8.3 because the
Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 

(h) The provisions of this Section 8.3 are for the benefit of the Indemnitees and their heirs, successors, assigns, executors and
administrators and shall not be deemed to create any rights for the benefit of any other Persons. 
 (i) No amendment, modification or repeal
of this Section 8.3 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any
such Indemnitee under and in accordance with the provisions of this Section 8.3 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in
part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 
 Section 8.4
Limitation of Liability of Indemnitees. 
 (a) Notwithstanding anything to the contrary set forth in this Agreement or under the Act
or any other law, rule or regulation at equity, no Indemnitee shall be liable for monetary damages or otherwise to the Partnership, to another Partner, to any other Person who acquires an interest in the Partnership or to any other Person bound by
this Agreement, for losses sustained or liabilities incurred, of any kind or character, as a result of its or any other Indemnitee’s determinations, act(s) or omission(s) in their capacities as Indemnitees; provided however, that an Indemnitee
shall be liable for losses or liabilities sustained or incurred by the Partnership, any Partners, any other Persons who acquire an interest in the Partnership or any other Person bound by this Agreement, if it is determined by a final non-appealable
judgment entered by a court of competent jurisdiction that such losses or liabilities were the result of the conduct engaged by such Indemnitee being in in Bad Faith or with respect to any criminal conduct, with the knowledge that such
Indemnitee’s conduct was unlawful. 
 (b) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties)
and liabilities relating thereto to the Partnership, any Partners, any other Persons who acquire an interest in the Partnership or any other Person bound by this Agreement, the General Partner and any other Indemnitee acting in connection with the
Partnership’s business or affairs shall not be liable to the Partnership, to any Partner, to any person who acquires an interest in the Partnership or to any other Person bound by this Agreement for its reliance on the provisions of this
Agreement. 

  
 15 








 (c) Any amendment, modification or repeal of this Section 8.4 or any provision hereof
shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 8.4 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 

Section 8.5 Loans or Contributions from the Partnership. The Partnership may lend or contribute to any Affiliate or Limited
Partner, and any Affiliate or Limited Partner may borrow from the Partnership, funds on terms and conditions determined by the General Partner.

Section 10.1 Tax Matters Partner. The “tax matters partner” of the Partnership for purposes of Section 6231(a)(7)
of the Code shall be the General Partner, and shall have the power to manage and control, on behalf of the Partnership, any administrative proceeding at the Partnership level with the Internal Revenue Service relating to the determination of any
item of Partnership income, gain, loss, deduction or credit for federal income tax purposes. 
 Section 10.2 Section 754

ARTICLE XI 

DISSOLUTION AND LIQUIDATION 

Section 11.1 Events Causing Dissolution. The Partnership shall be dissolved, and its affairs shall be wound up, upon the
expiration of its term as provided in Section 2.4. Upon the dissolution of the Partnership, the General Partner shall promptly notify the Partners of such dissolution. 

Section 11.2 Liquidation. 

(a) Upon dissolution of the Partnership, the General Partner shall carry out the winding up of the Partnership and shall immediately commence
to wind up the Partnership’s affairs; provided, a reasonable time shall be allowed for the orderly liquidation of the assets of 

  
 16 








 
the Partnership and the satisfaction of liabilities to creditors so as to enable the Partners to minimize the normal losses attendant upon a liquidation. The proceeds of liquidation shall be
applied first to payment of all expenses and debts of the Partnership and setting up of such reserves as the General Partner reasonably deems necessary to wind up the Partnership’s affairs and to provide for any contingent liabilities or
obligations of the Partnership; provided, the unpaid principal of and interest on any loans made to the Partnership by Partners (and their Affiliates) shall be distributed pro rata to the Partners (and their Affiliates) who made such loans, in
proportion to the total amount of principal and interest payable on such loans, such distributions being treated first as a payment of accrued interest on such loans and next as a payment of principal on such loans. Any remaining proceeds shall be
distributed to the Partners in accordance with their positive Capital Account balances after giving effect to all contributions, distributions and allocations for all periods. 

(b) In the event of any liquidation and winding up of the Partnership under this Section 10.2 or a sale, exchange or other disposition of
all or substantially all of the assets of the Partnership, either voluntary or involuntary, Profits and Losses and each item of gross income, gain, loss and deduction for such period shall be allocated to the Partners so that, to the maximum extent
possible, the Partners’ Capital Account balances are in proportion to their Percentage Interests, and no other allocation of Profit or Loss pursuant to this Agreement shall reverse the effect of such allocation. If in the year of such
liquidation, dissolution or winding up, the Partners’ Capital Accounts are not in proportion to their Percentage Interests after the application of the preceding sentence, then to the extent permitted by Law and notwithstanding anything to the
contrary contained in this Agreement, items of gross income and gain for any preceding taxable period(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated among the Partners until
the Partners’ Capital Accounts are in proportion to their Percentage Interests, and no other allocation of Profit or Loss pursuant to this Agreement shall reverse the effect of such allocation. 

Section 11.3 Termination. The Partnership shall terminate when all of the assets of the Partnership, after payment of or due
provision for all debts, liabilities and obligations of the Partnership, shall have been distributed to the Partners in the manner provided for in this Article 11 and the Certificate shall have been canceled, or such other documents required under
the Act to be executed and filed with the Secretary of State of the State of Delaware have been so executed and filed, in the manner required by the Act. 

Section 11.4 Claims of the Partners or Third Parties. The Partners and former Partners shall look first to the Partnership’s
assets for the return of their Capital Contributions, and if the assets of the Partnership remaining after payment of or due provision for all debts, liabilities and obligations of the Partnership are insufficient to return such Capital
Contributions, the Partners shall look to the General Partner for a return of their Capital Contributions; provided, nothing contained herein shall be deemed to limit the rights of a Partner under applicable Law. In the event any Partner other than
the General Partner has a deficit balance in its Capital Account at the time of the Partnership’s dissolution, it shall not be required to restore such account to a positive balance or otherwise make any payments to the Partnership or its
creditors or other third parties in respect of such deficiency. 

  
 17 








 Section 11.5 Distributions In-Kind. If any assets of the Partnership shall be
distributed in kind, such assets shall be distributed to the Partner(s) entitled thereto as tenants-in-common in the same proportions as such Partner(s) would have been entitled to cash distributions if (i) such assets had been sold for cash by
the Partnership at the fair market value of such property (taking the Gross Asset Value definition herein and Code Section 7701(g) into account) on the date of distribution; (ii) any unrealized income, gain, loss and deduction inherent in
such property (that has not been reflected in the Capital Accounts previously) that would be realized by the Partnership from such sale were allocated among the Partner(s) as Profits or Losses in accordance with this Agreement; and (iii) the
cash proceeds were distributed to the Partner(s) in accordance with this Article 11. The Capital Accounts of the Partner(s) shall be increased by the amount of any unrealized income or gain inherent in such property or decreased by the amount of any
loss or deduction inherent in such property that would be allocable to them, and shall be reduced by the fair market value of the assets distributed to them under the preceding sentence. Notwithstanding the foregoing, the Partners shall have the
right to assign their interest to such in-kind distribution to any Person. 
 ARTICLE XII
