Each Member has contributed or agrees to contribute to the Company the amount of capital having the value set forth opposite such Member’s name on Schedule C in exchange for its Membership Interest which capital shall be contributed in such form as may be required to enable the Company to acquire the Company Assets pursuant to the Purchase Agreement and the Buyers Agreement.

(b) Additional Capital Contributions. If a Designated Manager determines (after taking into account any existing cash reserves of the Company) that capital is needed to (i) restore operating reserves to a level as contemplated in the applicable Approved Business Plan or Annual Budget, (ii) fund any cash needs of the Company as contemplated in any applicable Approved Business Plan or as would not exceed the amounts that may be expended in accordance with Section 4.3(i), or arise pursuant to Authorized Unilateral Decisions, (iii) fund

Within ten (10) Business Days following the date of receipt of a Funding Notice, each Member shall pay to the Company as a Capital Contribution such Member’s Proportionate Share of the Additional Capital Requested Amount. Any funds advanced by the Members to the Company pursuant to this Section constitute additional Capital Contributions to the Company.

(e) Capital Accounts. The Company shall establish and maintain an individual Capital Account for each Member.

Section 3.4 Failure to Contribute Capital.

If any Member fails to make a Capital Contribution required under Section 3.3(b) by the date such Capital Contribution is due and such failure continues for ten (10) Business Days after written notice from the Member which has not failed to make its Capital Contribution (any such failing Member shall be a “Capital Defaulting Member” and the amount of the failed Capital Contribution shall be the “Capital Default Amount”), then the non-Capital Defaulting Member shall have any one and only one of the following remedies:

(a) to advance to the Company (or, at its election, cause any of its Affiliates to advance to the Company) on behalf of, and as a loan to, the Capital Defaulting Member, an amount equal to the Capital Default Amount (each such loan, a “Capital Default Loan”). The Capital Account of the Capital Defaulting Member shall be credited with the amount of such Capital Default Loan, which shall be deemed to be a Capital Contribution made by the Capital Defaulting Member, and such amount shall constitute a debt owed by the Capital Defaulting Member to the non-Capital Defaulting Member (or its applicable Affiliate that has funded the Capital Default Loan). Any Capital Default Loan shall bear interest at a rate equal to 15% per annum and shall be payable from any distributions due the Capital Defaulting Member hereunder, but shall in all events be payable in full by the ninetieth (90th) day following the date such Capital Default Loan was made. Interest on a Capital Default Loan to the extent unpaid shall accrue and compound monthly. A Capital Default Loan shall be prepayable at any time or from time to time without penalty. While any Capital Default Loan is outstanding,

notwithstanding anything in this Agreement to the contrary, all distributions to the Capital Defaulting Member hereunder shall be applied first to payment of any interest due under any Capital Default Loan and then to principal until all amounts due thereunder are paid in full. All payments made in repayment of any Capital Default Loan shall be applied first toward payment of unpaid accrued interest and then (if any remains) toward payment of principal. If a Capital Default Loan is not paid on or prior to the date such Capital Default Loan becomes due, the non-Capital Defaulting Member (or its applicable Affiliate that has funded the Capital Default Loan) may pursue all available rights and remedies against the Capital Defaulting Member and, pursuant to the applicable Parent Guaranty, its Parent (and if the non-Capital Defaulting Member’s Affiliate has funded the Capital Default Loan, it shall be entitled to all of the rights of a non-Capital Defaulting Member under this Section 3.4, including all rights to enforce the Parent Guaranty as if it were the “Creditor Member” thereunder);

(b) to revoke the Funding Notice for both Members, whereupon any Capital Contributions paid by the non-Capital Defaulting Member pursuant to such Funding Notice shall be returned, in which event the Members may reconsider the needs of the Company for additional Capital Contributions, and any Member may thereafter issue any Funding Notice as permitted hereunder following such reconsideration; or

(c) to contribute its required Capital Contribution and pursue its rights under the Parent Guaranty delivered by the Parent of the Capital Defaulting Member with respect to such Capital Default Amount.

Unless the non-Capital Defaulting Member shall have elected to revoke the Funding Notice for both Members pursuant to Section 3.4(b), then, until either the Capital Default Loan made by the non-Capital Defaulting Member shall have been repaid in full or the amounts due with respect to such Capital Contribution have been funded by the Capital Defaulting Member or its Parent pursuant to the Parent Guaranty, the Capital Defaulting Member and the Management Committee Representatives appointed by it shall have no voting or approval rights hereunder. Such voting and approval rights shall be restored in the event that the Capital Defaulting Member (or its Parent, pursuant to its Parent Guaranty) repays the Capital Default Loan in accordance with the terms of this Agreement, but the Capital Defaulting Member and the Management Committee Representatives appointed by it shall be bound by all decisions that were made without its or their approval while the Capital Default Loan was outstanding. Notwithstanding the foregoing, under no circumstances shall the non-Capital Defaulting Member or the Management Committee Representatives appointed by it have any authority, without the written consent of the Capital Defaulting Member or, as applicable, the Management Committee Representatives appointed by it, to cause the Company to incur on behalf of the Company any indebtedness which includes any recourse obligations of any Member, to engage in any transaction with any Affiliate of the non-Capital Defaulting Member, or to amend this Agreement, nor shall the Capital Defaulting Member forfeit any of its rights to receive distributions, to receive reports or obtain information as a result of the making of any Capital Default Loan.

Section 3.5 Parent Guaranty Delivered to the AVB Member.

Concurrently with the execution and delivery of this Agreement, AVB has delivered its Parent Guaranty to ERP Member, and ERP has delivered its Parent Guaranty to AVB Member. No creditor or third party shall have rights to enforce any obligations under such Parent Guaranty.

Section 3.6 Parent Guaranties delivered to Third Parties.

(a) Allocation of Guaranty Liability. Subject to Section 3.6(c) below, liability under any Guaranty Obligation that is delivered by any of the Members or their Parents with respect to any Indebtedness or Contingent Obligation of the Company or any Subsidiary Entity shall, as between the Members and their Parents, be apportioned in proportion to the Members’ Proportionate Shares, and any payments made under any such Guaranty Obligation (other than payments made by a Responsible Member) shall be deemed additional Capital Contributions to the Company.

(b) Guaranty Equalization Payments. Subject to Section 3.6(c), if at any time a Member or its Affiliate or Parent shall have made a payment under or otherwise satisfied any Guaranty Obligation with respect to any Indebtedness or Contingent Obligation of the Company or any Subsidiary Entity, and on or prior to such time, the other Member or its Affiliate or Parent shall not have made a payment under or otherwise satisfied an equivalent Guaranty Obligation with respect to the same Indebtedness or Contingent Obligation of the Company or any Subsidiary Entity in an amount that is in proportion to its Proportionate Share of the aggregate cumulative amounts by which both Members and their Affiliates and Parents have made payments under or otherwise satisfied such Guaranty Obligations, then the Member (the “Under-Guarantying Member”) that has (together with its Affiliates and Parent) paid amounts or otherwise satisfied amounts on account of such aggregate Guaranty Obligations that are less than its Proportionate Share of the aggregate cumulative amounts paid or satisfied by both Members and their Affiliates and Parents under such aggregate Guaranty Obligations shall, immediately upon demand by the other Member (the “Over-Guarantying Member”), pay or cause to be paid to the Over-Guarantying Member (on behalf of itself and as applicable its Affiliates and Parent) such sums (each, a “Guaranty Equalization Payment”) as may be sufficient to cause the sum of the amounts by which such aggregate Guaranty Obligations have been paid or satisfied by the Over-Guarantying Member and its Affiliate and Parent, minus the amount of the Guaranty Equalization Payment so paid to the Over-Guarantying Member, to equal the Over-Guarantying Member’s Proportionate Share of the aggregate cumulative amounts by which such aggregate Guaranty Obligations have been paid or satisfied by both Members and their Affiliates and Parents. The obligation of the Under-Guarantying Member and its Parent to make such Guaranty Equalization Payment shall be absolute, irrevocable and unconditional under any and all circumstances whatsoever and irrespective of any set-off, counterclaim or defense to payment which the Under-Guarantying Member or its Affiliate or Parent may have or claim to have against the obligee of the Guaranty Obligations. If the Under-Guarantying Member does not pay the Guaranty Equalization Payment or cause it to be paid to the Over-Guarantying Member (on behalf of itself and as applicable its Affiliates and Parent) immediately upon demand therefor, then the unpaid amount of such Guaranty Equalization Payment shall bear interest at the rate applicable to Capital Default Loans until paid in full (which interest shall

be immediately due and payable), and, without limiting any other available rights or remedies of the Over-Guarantying Member against the Under-Guarantying Member or its Parent (including any rights or remedies under such Parent’s Parent Guaranty), any distributions or payments thereafter otherwise payable by the Company to the Under-Guarantying Member shall be withheld from such Member and instead paid to the Over-Guarantying Member until such time as the full amount of the Guaranty Equalization Payment (plus all accrued but unpaid interest thereon) has been paid to the Over-Guarantying Member. The Under-Guarantying Member shall be deemed a Capital Defaulting Member for purposes of this Agreement and shall lose voting rights as more particularly set forth in Section 3.4 until the Under-Guarantying Member has paid, or caused to be paid, the Guaranty Equalization Payment.

(c) Carveout Exposure. Notwithstanding the provisions of Sections 3.6(a) or (b) to the contrary, if any amount is paid or payable under any Indebtedness or Contingent Obligation of the Company or any Subsidiary Entity, or under any Guaranty Obligation of any Member or its Parent with respect to any Indebtedness or Contingent Obligation of the Company or any Subsidiary Entity, as a result of any act or omission on the part of one of the Members or their Affiliates which is not an Authorized Unilateral Decision or not reasonably within the scope of decisions, actions or transactions that were Approved by the Members or Approved by the Management Committee, then the Member whose act or omission (or whose Affiliate’s act or omission) solely resulted in the obligation to make such payment (such Member, the “Responsible Member”) shall have exclusive responsibility, as between the Members, for satisfying the payment obligations arising under such Indebtedness, Contingent Obligation or Guaranty Obligation as a result of such act or omission of the Responsible Member or its Affiliate; the Responsible Member shall have no rights to require the other Member or its Parent to make any Guaranty Equalization Payment on account of any such payment obligations; and the Responsible Member shall indemnify, defend, protect and hold harmless the Company, the other Member and its Parent from any losses, damages, liabilities, costs and expenses, including prepayment premiums, default rate interest, legal fees and disbursements, arising from any such act or omission under any such Indebtedness, Contingent Obligation or Guaranty Obligation, except, in each case, to the extent that the amount so paid or payable under such Indebtedness, Contingent Obligation or Guaranty Obligation is applied to reduce the principal balance due upon such Indebtedness or the principal balance due upon Indebtedness that is guaranteed or supported by such Contingent Obligation or Guaranty Obligation.

(d) Schedule F which is or may be attached hereto identifies the Guaranty Obligations of the Members, their Parents and Affiliates as of the date of this Agreement and may include certain additional provisions applicable thereto.

Section 5.3 Withholding.

(a) General. Each Member shall, to the fullest extent permitted by applicable law, indemnify and hold harmless the Company and each Covered Person who is or who is deemed to be the responsible withholding agent for U.S. federal, state or local or non-U.S. income tax purposes against all claims, liabilities and expenses of whatever nature relating to the Company’s or such Covered Person’s obligation to withhold and to pay over, or otherwise pay, any withholding or other taxes payable by the Company with respect to such Member or as a result of such Member’s participation in the Company.

To the extent that such payment exceeds the cash distribution that such Member would have received but for such withholding, ERP Member shall notify such Member as to the amount of such excess and such Member shall make a prompt payment to the Company of such amount by wire transfer, which payment shall not constitute a Capital Contribution and, consequently, shall not increase the Capital Account of such Member.

(b) No Covered Person shall be liable to the Company or to any Member for any loss or damage sustained by the Company or any Member, unless the loss or damage shall have been the result of fraud, gross negligence, willful misconduct or a willful, knowing or intentional breach of this Agreement by such Covered Person, or the result of any act or omission performed or omitted by such Covered Person not in good faith.

(c) To the fullest extent permitted by law, unless it is determined that a Covered Person is not entitled to be indemnified therefor pursuant to this Section 7.1, expenses incurred by such Covered Person in defending any claim, demand, action, suit or proceeding subject to this Section shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of an undertaking by or on behalf of the Covered Person to repay such amount.

(d) The indemnification provided by this Section 7.1 shall be in addition to any other rights to which any Covered Person may be entitled under this Agreement, any other agreement, as a matter of law or otherwise, and shall inure to the benefit of the heirs, legal representatives, successors, assigns and administrators of the Covered Person.

Section 7.2 Procedures; Survival.

(a) If a Covered Person wishes to make a claim under Section 7.1, the Covered Person should notify the Company in writing within ten (10) days after receiving written notice of the commencement of any action that may result in a right to be indemnified under Section 7.1; provided however that the failure to notify the Company shall not relieve the Company of any liability for indemnification pursuant to Section 7.1 (except to the extent that the failure to give notice will have been materially prejudicial to the Company).

(b) A Covered Person shall have the right to employ separate legal counsel in any action pursuant to Section 7.1 and to participate in the defense of the action.

It is understood, however, that the Company shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of only one separate firm of attorneys at any time for all such Covered Persons having actual or potential differing interests with the Company.

Section 8.4 Transfer of Interests in Equity Residential, ERP or AVB.

Notwithstanding anything to the contrary contained in this Agreement, (a) neither Transfers of interests in ERP, nor the issuance or redemption of interests in ERP, nor Transfers of common or preferred shares or other equity interests in Equity Residential, nor issuance or redemption of common or preferred shares or other equity interests in Equity Residential (other than those occurring in connection with an Extraordinary Transaction), shall constitute a “Transfer” of the interest of ERP Member under this Agreement, or constitute a default, breach or withdrawal by ERP Member or any other violation of this Agreement by ERP Member; (b)

neither Transfers of shares of stock in AVB, nor issuance or redemption of shares of stock in AVB (other than those occurring in connection with an Extraordinary Transaction), shall constitute a “Transfer” of the interest of AVB Member under this Agreement, or constitute a default, breach or withdrawal by AVB Member or any other violation of this Agreement by AVB Member; and (c) notwithstanding clauses (a) and (b) above, neither any merger or other consolidation of Equity Residential, ERP or AVB with any other Person, nor any transfer of all or substantially all of the common equity of Equity Residential, ERP or AVB (including by way of tender offer), nor any sale of all or substantially all of the assets of Equity Residential, ERP or AVB, nor any transfer, issuance or redemption of common or preferred shares or other equity interests in ERP or Equity Residential or AVB, as applicable, in connection with such a merger or consolidation of Equity Residential, ERP or AVB, as applicable (each, an “Extraordinary Transaction”), shall constitute a “Transfer” of the interest of ERP Member or AVB Member, as applicable, under this Agreement, or constitute a default, breach or withdrawal by ERP Member or AVB Member, as applicable, or any other violation of this Agreement by ERP Member or AVB Member, as applicable, so long as, in the case of any such Extraordinary Transaction, the surviving Entity or buyer (the “Successor Parent”), as applicable, in any such transaction provides notice of such transaction to the other Member within five (5) Business Days thereafter and certifies that as of the date of consummation of, and after giving effect to, such transaction, it is either (i) a publicly traded company which continues to qualify as a REIT and has total equity as determined in accordance with U.S. generally accepted accounting principles of not less than $1.5 billion, or (ii) it has total equity as determined in accordance with U.S. generally accepted accounting principles of not less than $2 billion.

Section 12.13 Dispute Resolution; Mediation.

In the event of any claim, dispute or other matter in controversy between the Members arising under this Agreement, each Member agrees that, prior to commencing any lawsuit relating to such claim, dispute or other matter in controversy, (i) it shall notify the other Member in writing of the claim, dispute or other matter in controversy, including a reasonably detailed explanation of such Member’s understanding of the respective positions of each of the Members with respect to the matters in dispute; (ii) the respective chief executive officers of Equity Residential and AVB or their designees shall meet and confer at a mutually convenient time and

place within twenty (20) Business Days following the request of either Member concerning such claim, dispute or other matter in controversy (such period is referred to herein as the “Discussion Period”); (iii) if the Members are unable during the Discussion Period to reach a final agreement concerning such claim, dispute or other matter in controversy, then, prior to commencing any lawsuit relating to such dispute, the Member that would intend to commence such lawsuit shall deliver a written request to the other Member for non-binding mediation to be administered by the New York, New York office of Judicial Arbitration & Mediation Services, Inc. or its successor (“JAMS”) or any other office of JAMS agreed to by the Members, in accordance with JAMS’s mediation procedures in effect on the date of the Agreement (and if the Members cannot agree on the selection of a mediator, the Member asserting the claim, dispute or controversy shall file a request in writing for the appointment of a mediator with the New York, New York office of JAMS, with a copy of the request being served on the other Member, and the mediation shall be conducted by the appointed mediator). Mediation shall proceed in advance of the commencement of any lawsuit for a period of 60 days from the date that the applicable Member’s request for commencement of the mediation procedure was delivered to the other Member. The parties shall share the mediator’s fee and any filing fees equally. Without limiting any other applicable limitation in this Agreement, in no event shall the procedures and limitations set forth in this Section 12.13 limit or condition the right of any Member to commence a lawsuit against any third party or to file an answer or counterclaim or cross-claim (including, without limitation, as against the other Member) in any lawsuit that has been commenced by any third party. The Members agree that the provisions in this Section 12.13 shall apply to any claim, dispute or controversy asserted by any Member, but once the Members have engaged in the Discussion Period and mediation procedures provided for herein with respect to such claim, dispute or controversy, no Member shall be bound to comply with the Discussion Period and mediation procedures provided for herein with respect to any further claim, dispute or controversy that relates to substantially the same acts, omissions or occurrences with respect to which the Discussion Period and mediation procedures provided for herein have already taken place. The Members agree that the discussions during the Discussion Period or in connection with such mediation procedures are intended to be settlement communications, and accordingly (i) none of the discussions during the Discussion Period or in connection with such mediation procedures, nor any proposals (whether written or oral), correspondence, or documents of any kind generated during the period of and in connection with the Discussion Period or in connection with such mediation procedures, shall be raised, disclosed or admissible in any judicial, arbitration or similar proceeding for any purpose nor shall any such discussions, proposals, correspondence or documents be used as a defense or counter-claim in any action; (ii) such discussions, proposals, correspondence or documents are without prejudice to any of the parties’ rights, defenses and remedies at law, in equity or hereunder; and (iii) neither the preparation, distribution, response to or failure to respond to any such discussions, proposals, correspondence or documents shall constitute an agreement, or the basis on which any party may claim reliance on any agreement, except to the extent that the Members in connection with the discussions during the Discussion Period or in connection with such mediation procedures enter into a written agreement that is intended to be definitive and binding. The foregoing provisions are intended to be broader than the restrictions on admissibility with respect to settlement discussions contained in any applicable state or federal statute or rule of court, including, without limitation, Rule 408 of the Federal Rules of Evidence. If the Members or Management Committee Representatives reach an impasse over a proposed Major Decision or any other

proposed decision requiring the Approval of the Members or the Approval of the Management Committee, at the election of either Member, upon not less than ten (10) Business Days’ notice to the other Member, the Discussion Period and non-binding mediation process provided for in this Section 12.13 shall be commenced, to assist the Members in attempting to resolve the impasse, notwithstanding that no claim, dispute or other controversy with respect to which a Member may seek to commence a lawsuit then exists with respect to such matter.

Section 12.14 Specific Performance.

Because of the unique character of the Membership Interests, the Members and the Company shall be irreparably damaged if this Agreement is not specifically enforced. If any dispute arises concerning the Transfer of all or any part of a Member’s Membership Interest, an injunction may be issued restraining any purported Transfer pending the determination of such controversy. Such remedy shall, however, be cumulative and not exclusive, and shall be in addition to any other remedy which the Members or the Company may have.

Section 12.15 No Third Party Beneficiary.

This Agreement is made solely and specifically among and for the benefit of the parties hereto, and their respective successors and permitted assigns, and no other Person shall have any rights, interest, or claims hereunder or be entitled to any benefits under or on account of this Agreement as a third party beneficiary or otherwise.

Section 12.16 Waiver of Jury Trial.

EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY OR CLAIM WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS. THIS WAIVER MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING (OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SECTION 12.16) AND EXECUTED BY EACH OF THE PARTIES HERETO). The scope of this waiver is intended to be all-encompassing of any and all disputes that may be filed in any court and that relate to the subject matter herein, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

Section 12.17 Cumulative Remedies.

The rights and remedies of any party as set forth in this Agreement are not exclusive and are in addition to any other rights and remedies now or hereafter provided by law or at equity, subject to the provisions of Section 12.13 hereof.

It is the express intention and agreement of the Members that all covenants, agreements, statement, representations, warranties and indemnities made in this Agreement shall survive the execution and delivery of this Agreement and, where appropriate to facilitate the intent of this Agreement, the dissolution, liquidation and winding up of the Company.

Section 12.21 Attorneys’ Fees.

If any Member seeks to enforce such Member’s rights under this Agreement by legal proceedings or otherwise the non-prevailing party shall be responsible for all costs and expenses in connection therewith, including without limitation, reasonable attorneys’ fees and costs and court costs and witness fees.

Each Member shall not disclose or furnish to any third party (other than any third party who is bound by confidentiality obligations reasonably expected to prevent further disclosure) the terms and conditions of this Agreement. Notwithstanding the foregoing, each Member may disclose the terms and conditions of this Agreement to the extent such disclosure is reasonably necessary to comply with applicable law (including any securities law or regulation or the rules of a securities exchange) and with judicial process, and to its affiliates, partners, managers, trustees, directors, officers, employees, accountants, attorneys, advisors and other representatives, each of whom shall be informed of the confidential nature of the terms and conditions of this Agreement and directed to treat such information confidentially in accordance with the terms of this Agreement.

Archstone Parallel Residual JV 2, LLC

GUARANTY

THIS GUARANTY (this “Guaranty”), dated as of the 27th day of February, 2013, is made by AVALONBAY COMMUNITIES, INC., a Maryland corporation (“Guarantor”), for the benefit of EQR-PARALLEL RESIDUAL JV 2 MEMBER, LLC, a Delaware limited liability company (“Creditor Member”).

RECITALS

A. Creditor Member and AVB RESIDUAL PARALLEL II, LLC, a Delaware limited liability company (“Guarantor-Affiliated Member”), formed and own the membership interests in Archstone Parallel Residual JV 2, LLC, a Delaware limited liability company (the “Company”), pursuant to that certain Limited Liability Company of the Company dated as of even date herewith (as the same may be amended from time to time, the “Limited Liability Company Agreement”). All capitalized terms which are used but not expressly defined in this Guaranty shall have the same meaning herein as are given to such terms in the Limited Liability Company Agreement.

B. Guarantor has an indirect or direct financial and/or ownership interest in Guarantor-Affiliated Member.

C. In partial consideration of Guarantor-Affiliated Member’s execution of the Limited Liability Company Agreement and as a condition precedent thereto, the Guarantor is required to execute and deliver this Guaranty for the benefit of Creditor Member and its permitted successors and assigns under the Limited Liability Company Agreement (collectively, “Beneficiary”).

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and in order to induce Creditor Member to enter into the Limited Liability Company Agreement, Guarantor hereby agrees as follows:

1. GUARANTY. Guarantor, as primary obligor and not merely as a surety, hereby absolutely and irrevocably guarantees to Beneficiary the punctual payment and performance when due of the Guaranteed Obligations (as hereinafter defined). As used herein, “Guaranteed Obligations” means, collectively, (i) the full and prompt payment of all amounts, capital contributions, sums and charges payable by Guarantor-Affiliated Member under the Limited Liability Company Agreement, including, without limitation, all obligations of Guarantor-Affiliated Member to make Guaranty Equalization Payments and all indemnification obligations of Guarantor-Affiliated Member under the Limited Liability Company Agreement, (ii) the full and punctual performance and observance of all the terms, covenants and conditions provided to be performed, observed and complied with by Guarantor-Affiliated Member under the Limited Liability Company Agreement, or provided to be performed, observed and complied with by Guarantor-Affiliated Member or an affiliate or designee thereof (each, individually and collectively, “Obligor”) under any assumption agreement or other instrument delivered by it pursuant to the Limited Liability Company Agreement, whether in respect of any Office Lease or otherwise, and (iii) the full and prompt payment of all damages, costs and expenses which shall

at any time be recoverable by Creditor Member from Guarantor-Affiliated Member or any other Obligor by virtue of or under the Limited Liability Company Agreement or under any assumption agreement or other instrument delivered by it pursuant to the Limited Liability Company Agreement, including, without limitation, on account of any representations or warranties made by Guarantor-Affiliated Member thereunder. Guarantor further agrees to pay all Enforcement Costs (as hereinafter defined), in addition to all other amounts due hereunder. Any amounts owed under this Guaranty (that are not accruing interest under the Limited Liability Company Agreement) which are not timely made by Guarantor in accordance with the terms of this Guaranty shall bear interest from the date payable at the rate of fifteen percent (15%) per annum until all such amounts are fully paid. Notwithstanding anything to the contrary herein, (x) Guarantor shall have all of the same rights, remedies and defenses as Guarantor-Affiliated Member, including, without limitation, the right to exercise the dispute resolution procedures under and in accordance with the terms of the Limited Liability Company Agreement, and (y) other than the payment of Enforcement Costs, Guarantor shall have no greater liability than Guarantor-Affiliated Member or other Obligor under the Limited Liability Company Agreement or with respect to any assumption agreement or instrument delivered by it pursuant thereto.

2. NATURE OF GUARANTY. This Guaranty is an absolute, irrevocable, present and continuing guaranty of payment and performance and not of collectability. The obligations of Guarantor hereunder are independent of the obligations of Guarantor-Affiliated Member and any other Obligor and, in the event of any default hereunder, a separate action or actions may be brought and prosecuted against Guarantor whether or not Guarantor-Affiliated Member or any other Obligor is joined therein. Beneficiary shall not be required to prosecute collection, enforcement or other remedies against Guarantor-Affiliated Member or any other Obligor or any other guarantor of the Guaranteed Obligations, or to enforce or resort to any collateral for the repayment of the Guaranteed Obligations or other rights and remedies pertaining thereto, before calling on the Guarantor for payment. If for any reason Guarantor-Affiliated Member or any other Obligor shall fail or be unable to pay, punctually and fully, any of the Guaranteed Obligations, Guarantor shall pay such obligations to Beneficiary in full, immediately upon demand. One or more successive actions may be brought against Guarantor, as often as Beneficiary deems advisable, until all of the Guaranteed Obligations are paid and performed in full. Payment or performance by Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid and performed. Without limiting the generality of the foregoing, if Creditor Member is awarded a judgment in any suit brought to enforce Guarantor’s covenant to pay or perform a portion of the Guaranteed Obligations, such judgment shall not be deemed to release Guarantor from its covenant to pay and perform the portion of the Guaranteed Obligations that is not the subject of such judgment.

3. ENFORCEMENT COSTS. If: (a) this Guaranty, is placed in the hands of one or more attorneys for collection or is collected through any legal proceeding, (b) one or more attorneys is retained to represent Beneficiary in any bankruptcy, reorganization, receivership or other proceedings affecting creditors’ rights and involving a claim under this Guaranty, or (c) one or more attorneys is retained to represent Beneficiary in any other proceedings whatsoever in connection with this Guaranty, then Guarantor shall pay to Beneficiary upon demand all fees, reasonable costs and expenses incurred by Beneficiary in connection therewith,

including, without limitation, reasonable attorney’s fees, court costs and filing fees (all of which are referred to herein as the “Enforcement Costs”). Beneficiary is only entitled to Enforcement Costs if it is the prevailing party.

4. NO DISCHARGE OR DIMINISHMENT OF GUARANTY. Except as otherwise provided herein and to the extent provided herein, the obligations of Guarantor hereunder are absolute and not subject to termination for any reason other than the satisfaction of the Guaranteed Obligations or expiration of this Guaranty. Guarantor agrees that the liability of the Guarantor hereunder shall not be discharged by, and Guarantor hereby irrevocably consents to: (i) any subsequent change, modification or amendment of the Limited Liability Company Agreement in any of its terms, covenants and conditions; (ii) the renewal or extension of time for the payment or performance of the Guaranteed Obligations; (iii) any transfer, waiver, compromise, settlement, modification, surrender or release of Guarantor-Affiliated Member’s or any other Obligor’s obligations; (iv) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Limited Liability Company Agreement, at law, in equity or otherwise) with respect to the Guaranteed Obligations; (v) any act or event which might otherwise discharge, reduce, limit or modify Guarantor’s obligations under this Guaranty; and (vi) any forbearance, delay or other act or omission of Creditor Member. In addition, the Guaranteed Obligations of the Guarantor hereunder are not subject to counterclaim (other than mandatory or compulsory counterclaims), set-off, abatement, deferment or defense based upon any claim that Guarantor may have against Beneficiary:

(a) unrelated to the transaction giving rise to the Guaranteed Obligations; or

(b) regarding any lack of capacity, lack of authority or any other disability or other defense of Guarantor-Affiliated Member or any other Obligor, including, without limitation, any defense based on or arising out of the lack of validity or enforceability of the Limited Liability Company Agreement or any assumption agreement or other instrument delivered thereunder; or

(c) regarding (i) the release or discharge of Guarantor-Affiliated Member or any other Obligor in any receivership, bankruptcy or other proceedings, (ii) the impairment, limitation, modification or termination of the liabilities of Guarantor-Affiliated Member or any other Obligor to Beneficiary or the estate of Guarantor-Affiliated Member or any other Obligor in bankruptcy, or any remedy for the enforcement of Guarantor-Affiliated Member’s or any other Obligor’s liability under the Limited Liability Company Agreement or any assumption agreement or other instrument delivered thereunder, resulting from the operation of any present or future provision of Title 11 of the United States Code or other statute or from the decision in any court, (iii) the cessation of the liability of Guarantor-Affiliated Member or any other Obligor from any cause other than payment and performance in full of the Guaranteed Obligations, or (iv) any rejection or disaffirmance of the Guaranteed Obligations, or any part thereof, or any security held therefor, in any proceedings in bankruptcy, insolvency or reorganization.

5. DEFENSES WAIVED. Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, to the fullest extent permitted by applicable law, any notice

(including, without limitation, notices of protest, notices of dishonor, notices of any action or inaction, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, and notices of any extension of credit to Guarantor-Affiliated Member or any other Obligor and any right to consent to any thereof) not provided for herein or in the Limited Liability Company Agreement, as well as any requirement that at any time any action be taken by any person against Guarantor-Affiliated Member, any other Obligor or Guarantor. Guarantor further irrevocably waives: (a) any right to require Creditor Member, as a condition of payment or performance, to (i) proceed against Guarantor-Affiliated Member or any other Obligor or other Person, (ii) proceed against or exhaust any security held from Guarantor-Affiliated Member or any other Obligor or other Person, (iii) proceed against or have resort to any balance on the books of Creditor Member owed to Guarantor-Affiliated Member or any other Obligor or other Person, or (iv) pursue any other remedy in the power of Creditor Member whatsoever; (b) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; and (c) the benefit of any statute of limitations affecting Guarantor’s liability hereunder or the enforcement hereof. Until payment of the Guaranteed Obligations by Guarantor-Affiliated Member and any other Obligor, any right of subrogation, contribution, reimbursement or indemnification on the part of Guarantor as against Guarantor-Affiliated Member or any other Obligor shall be in all respects subordinate to all rights and claims of Beneficiary for all other payments or damages which shall be or become due and payable by Guarantor-Affiliated Member or any other Obligor under the provisions of the Limited Liability Company Agreement or any assumption agreement or other instrument delivered thereunder. Beneficiary may compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with Guarantor-Affiliated Member or any other Obligor or exercise any other right or remedy available to it against Guarantor-Affiliated Member or any other Obligor without affecting or impairing in any way the liability of Guarantor under this Guaranty except to the extent the Guaranteed Obligations have been performed.

6. REINSTATEMENT; STAY OF ACCELERATION. If at any time any payment of any portion of the Guaranteed Obligations is rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, or reorganization of Guarantor-Affiliated Member or any other Obligor or otherwise, Guarantor’s obligations under this Guaranty with respect to that payment shall be reinstated at such time as though the payment had not been made. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of Guarantor-Affiliated Member or any other Obligor, all such amounts otherwise subject to acceleration under the terms of any agreement relating to the Guaranteed Obligations shall nonetheless be payable by Guarantor forthwith on demand by the Beneficiary.

7. INFORMATION. Guarantor assumes all responsibility for being and keeping itself informed of Guarantor-Affiliated Member’s or any other Obligor’s financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that Guarantor assumes and incurs under this Guaranty, and agrees that Beneficiary does not have any duty to advise Guarantor of any information known to it regarding those circumstances or risks.

8. SURVIVAL. This Guaranty shall remain in full force and effect as to any Guaranteed Obligation for so long as such Guaranteed Obligation survives under the terms and conditions of the Limited Liability Company Agreement.

9. SEVERABILITY. The provisions of this Guaranty are severable, and in any action or proceeding involving any state corporate, partnership or limited liability company law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of Guarantor under this Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of Guarantor’s liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the amount of such liability shall, without any further action by Guarantor or Beneficiary, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding. This Section with respect to the maximum liability of Guarantor is intended solely to preserve the rights of Beneficiary, to the maximum extent not subject to avoidance under applicable law, and neither Guarantor nor any other person or entity shall have any right or claim under this Section with respect to such maximum liability, except to the extent necessary so that the obligations of Guarantor hereunder shall not be rendered voidable under applicable law.

10. REPRESENTATIONS BY GUARANTOR. Guarantor represents that: (a) it is duly organized, validly existing and in good standing under the laws where it is organized and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted; (b) the execution and delivery of this Guaranty and the performance of the obligations it imposes (i) are within its powers; (ii) have been duly authorized by all necessary action of its governing body; and (iii) do not violate any law, conflict with the terms of its articles or agreement of incorporation or organization, its by-laws or any agreement by which it is bound or require the consent or approval of any governmental authority or any third party; and (c) this Guaranty is a valid and binding agreement, enforceable according to its terms, except as such enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally.

11. NOTICES. All notices, requests and other communications to any party under this Guaranty must be in writing (including facsimile transmission or similar writing) and must be given to Beneficiary at the address for Beneficiary set forth in the Limited Liability Company Agreement, to Guarantor-Affiliated Member at the address for Guarantor-Affiliated Member set forth in the Limited Liability Company Agreement, and to Guarantor at the address for Guarantor-Affiliated Member set forth in the Limited Liability Company Agreement, or in each case as otherwise specified in a notice by one party to the other in accordance with the Limited Liability Company Agreement. Each notice, request or other communication shall be effective in accordance with the Limited Liability Company Agreement.

12. MISCELLANEOUS. No provision of this Guaranty may be amended, supplemented or modified, or any of its terms and provisions waived, except by a written instrument executed by Beneficiary and Guarantor. No failure on the part of the Beneficiary to exercise, and no delay in exercising, any right under this Guaranty waives that right; nor does any single or partial exercise of any right under this Guaranty preclude any other or further exercise of that or any other right. The remedies provided in this Guaranty are cumulative and

not exclusive of any remedies provided by law. This Guaranty binds Guarantor, and its successors and assigns, and benefits Beneficiary, and its respective successors and assigns. The use of headings does not limit the provisions of this Guaranty.

13. ASSIGNMENT OF GUARANTY. Notwithstanding anything to the contrary contained in this Guaranty, Guarantor shall not assign, transfer or otherwise delegate its obligations under this Guaranty without first obtaining Beneficiary’s prior written consent, which shall be granted or withheld in Beneficiary’s sole and absolute discretion. No transfer of interests in Guarantor or merger involving Guarantor that is permitted under the Limited Liability Company Agreement shall be deemed to be an assignment that requires Beneficiary’s consent hereunder.

14. GOVERNING LAW. THIS GUARANTY IS TO BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF DELAWARE.

15. CONSENT TO JURISDICTION. GUARANTOR AND BENEFICIARY HEREBY CONSENT AND AGREE TO THE EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT SITTING IN THE STATE OF DELAWARE IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY AND GUARANTOR IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION IT MAY NOW OR LATER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH A COURT IS AN INCONVENIENT FORUM.

16. WAIVER OF JURY TRIAL. GUARANTOR AND BENEFICIARY ACKNOWLEDGE AND AGREE THAT ANY CONTROVERSY OR CLAIM WHICH MAY ARISE UNDER THIS GUARANTY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE CONTEMPLATED TRANSACTIONS. THIS WAIVER MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING (OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SECTION 16) AND EXECUTED BY EACH OF GUARANTOR AND BENEFICIARY). THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER HEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. IN THE EVENT OF LITIGATION, THIS GUARANTY MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

IN WITNESS WHEREOF, Guarantor has executed this Guaranty as of the date first above written.

TAXES; ALLOCATIONS; RELATED MATTERS

A. Target Allocations.

After application of Section B of this Schedule E, any remaining items of Profits and Losses shall be allocated among the Members and to their Capital Accounts so as to cause the balance of each Member’s Economic Capital Account to be as nearly equal to such Member’s Target Balance as possible.

B. Regulatory Allocations and other Allocation Rules.

Notwithstanding anything in the Agreement to the contrary, the following special allocations shall be made as follows, and, as appropriate, in the following order:

(1) Items of Company loss and deduction otherwise allocable to an Member hereunder that would cause such Member (hereinafter, a “Restricted Holder”) to have a deficit balance in his or her or its Adjusted Capital Account, or would increase the deficit balance in his or her or its Adjusted Capital Account, as of the end of the Fiscal Year to which such items relate shall not be allocated to such Restricted Holder.

(2) If there is a net decrease in Company Minimum Gain for any Fiscal Year (except as a result of conversion or refinancing of Company indebtedness, certain capital contributions or revaluation of the Company’s property as further outlined in Treasury Regulation Sections 1.704-2(d)(4), (f)(2) or (f)(3)), each Member shall be specially allocated items of Company income and gain for such year (and, if necessary, subsequent years) in an amount equal to that Member’s share of the net decrease in Company Minimum Gain. The items to be so allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section B(2) is intended to comply with the minimum gain chargeback requirement in said Section of the Treasury Regulations and shall be interpreted consistently therewith. Allocations pursuant to this Section B(2) shall be made in proportion to the respective amounts required to be allocated to each Member pursuant hereto.

(3) If there is a net decrease in Minimum Gain Attributable to Member Nonrecourse Debt during any Fiscal Year (other than due to the conversion, refinancing or other change in the debt instrument causing it to become partially or wholly nonrecourse, certain capital contributions, or certain reevaluations of the Company’s property as further outlined in Treasury Regulations Section 1.704-2(i)(4)), each Member shall be specially allocated items of Company income and gain for such year (and, if necessary, subsequent years) in an amount equal to that Member’s share of the net decrease in the Minimum Gain Attributable to Member Nonrecourse Debt. The items to be so allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(i)(4) and (j)(2). This Section B(3) is intended to comply with the minimum gain chargeback requirement with respect to Member Nonrecourse Debt contained in said Section of the Treasury Regulations and shall be interpreted consistently therewith. Allocations pursuant to this Section B(3) shall be made in proportion to the respective amounts required to be allocated to each Member pursuant hereto.

Schedule E-1

(4) In the event an Member unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6), and such Member has an Adjusted Capital Account Deficit, items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate the Adjusted Capital Account Deficit as quickly as possible. This Section B(4) is intended to constitute a “qualified income offset” under Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(5) Nonrecourse Deductions for any Fiscal Year or other applicable period shall be allocated to the Members in accordance with their Proportionate Share, but only as permitted by the Treasury Regulations.

(6) Member Nonrecourse Deductions for any Fiscal Year or other applicable period shall be specially allocated to the Member that bears the economic risk of loss for the debt (i.e., the Member Nonrecourse Debt) in respect of which such Member Nonrecourse Deductions are attributable (as determined under Treasury Regulations Section 1.704-2(b)(4) and (i)(1)).

(7) Allocations to Members whose interests vary during a year by reason of transfer, redemption, admission, capital contributions, or otherwise, shall be made as determined by the Management Committee in accordance with permissible methods under Section 706 of the Code.

C. Tax Allocations.

(1) Subject to Section C(2), items of income, gain, loss, deduction and credit to be allocated for income tax purposes (collectively, “Tax Items”) shall be allocated among the Members on the same basis as their respective book items, as provided in Sections A and B.

(2) If any Company property is subject to Section 704(c) of the Code or is reflected in the Capital Accounts of the Members and on the books of the Company at a value that differs from the adjusted tax basis of such property, then the Tax Items with respect to such property shall, in accordance with the requirements of Treasury Regulations Section 1.704-1(b)(4)(i), be shared among the Members in a manner that takes account of the variation between the adjusted tax basis of the applicable property and its value in the same manner as variations between the adjusted tax basis and fair market value of property contributed to the Company are taken into account in determining the Members’ share of Tax Items under Section 704(c) of the Code. The Management Committee is authorized to choose any reasonable method permitted by the Treasury Regulations pursuant to Section 704(c) of the Code, including the “remedial allocation” method, the “curative” method and the “traditional” method.

(3) Pursuant to Treasury Regulations Section 1.752-3, each Member’s interest in Company profits, for purposes of determining such Member’s shares of excess “nonrecourse liabilities” for such purpose shall be that Member’s Proportionate Share.

(4) Any payment of foreign tax that may be creditable against any Member’s United States federal income tax liability shall be allocated to the Members in a manner reasonably determined by the Management Committee and in accordance with Treasury Regulation 1.704-1(b)(4)(viii). Other tax credits shall be allocated to the Members in a manner reasonably determined by the Management Committee.

Schedule E-2

(5) The Members are aware of the income tax consequences of the allocations made by this Agreement and shall report their shares of Profits and Losses and other items of Company, gross income, gain, loss and deduction for income tax purposes consistently with this Agreement.

D. Tax Classification.

It is the intent of the Members that the Company shall always be operated in a manner consistent with its treatment as a “partnership” for federal, state and local income and franchise tax purposes. In accordance therewith, (a) no Member shall file any election with any taxing authority to have the Company treated otherwise, and (b) each Member hereby represents, covenants, and warrants that it shall not maintain a position inconsistent with such treatment. The Management Committee shall, except as otherwise required by applicable law, (i) not cause or permit the Company to elect (A) to be excluded from the provisions of Subchapter K of the Code, or (B) to be treated as a corporation or an association taxable as a corporation for any tax purposes; (ii) cause the Company to make any election reasonably determined to be necessary or appropriate in order to ensure the treatment of the Company as a partnership for all tax purposes; (iii) cause the Company to file any required tax returns in a manner consistent with its treatment as a partnership for tax purposes; and (iv) not take any action or cause any officer or agent or representative of the Company to take any action that would be inconsistent with the treatment of the Company as a partnership for such purposes.

E. [Reserved.]

F. Additional Tax Matters.

(1) The Tax Matters Member shall be the sole signatory to any federal, state, local and foreign tax on behalf of the Company, except to the extent any other Person is required by law to also sign such returns.

(2) The Tax Matters Partner shall take no action in such capacity without the authorization or consent of the other Members, other than (after reasonable notice to the other Member) such action as the Tax Matters Partner may be required to take by applicable law. The Tax Matters Partner shall comply with the responsibilities outlined in Sections 6222 through 6232 of the Code.

(3) The Tax Matters Partner shall not enter into any extension of the period of limitations for making assessments on behalf of the Members without first obtaining the written consent of each Member.

(4) The Tax Matters Partner shall not bind the Company to a settlement agreement without obtaining the written concurrence of the other Members. For purposes of this Section F(4), the term “settlement agreement” shall include a settlement agreement at either an administrative or judicial level. Any Member that enters into a settlement agreement with respect to any Company items (within the meaning of Section 6231(a)(3) of the Code) shall notify the other Members of such settlement agreement and its terms within ninety (90) calendar days after the date of settlement.

Schedule E-3

(5) The provisions of this Section F shall survive the termination of the Company or the termination of any Member’s interest in the Company and shall remain binding on the Members (with respect to the period of time during which such Person is a Member) for a period of time necessary to resolve with the Internal Revenue Service or the United States Department of the Treasury any and all matters regarding the United States federal income taxation of the Company.

(6) The Tax Matters Partner, in its capacity as the Tax Matters Partner, shall be reimbursed by the Company for any third party out-of-pocket costs and expenses reasonably incurred by it in the performance of its duties as Tax Matters Partner. No Member shall be reimbursed by the Company for any costs and expenses incurred by such Member in pursuing on its own behalf any of its rights to file petitions, seek judicial review, etc. under this Section F or in participating in Company-level administrative or judicial tax proceedings unless the other Member, in its sole discretion, agrees to such reimbursement.

(7) During any Company income tax audit or other income tax controversy with any governmental agency, the Tax Matters Partner shall keep the Members informed of all material facts and developments on a reasonably prompt basis. Prompt notice shall be given to the Members upon receipt of advice that the Internal Revenue Service or other taxing authority intends to examine any income tax return, or records or books of the Company.

(8) The cost of any adjustments to all Members and the cost of any resulting audits or adjustments of Members shall be borne solely by the Members without reimbursement by the Company.
