ARTICLE 1 — CONTRIBUTION OF INTERESTS

     1.1 Contribution of the Interests.

          (a) Equity Value and Issuance of Common Units. At each Closing, subject to the terms and conditions of this Agreement, each Contributor agrees to contribute and convey to the New Company the Company Interests directly owned by it and reflecting the same direct and indirect ownership in the Companies shown on the applicable Schedules A-1 through A-7, except as otherwise modified by the Tarragon Restructuring or the Northland Restructuring, as applicable (as to such Contributor, the “Contributed Companies”) which hold the Properties for which the necessary Lender Consents have been obtained (as to such Contributor, the “Contributed Properties”). Each Contributor shall, through its contribution of the Company Interests, contribute the Contributed Properties subject only to the Permitted Exceptions, the Leases, the Contracts, the Licenses and such other leases, contracts and licenses as may be permitted to be entered into hereafter in accordance with Section 7.1. To the extent more than one Contributor owns interests in the same Company, then, at Closing, all of the Company Interests in such Company that will be contributed to the New Company must be contributed at the same Closing. In consideration of such contribution and conveyance and in reliance on the representations and warranties of such Contributor contained in or made pursuant to the terms of this Agreement, the parties hereto agree to cause the New Company to issue at such Closing to such Contributor a Common Unit for each ten dollars ($10.00) of Equity Value so contributed by it. Each Contributor shall be admitted as a member of the New Company upon the initial issuance to such Contributor of Common Units under and in accordance with the terms of the Limited Liability Company Agreement. The term “Equity Value” means, for each Contributor on each Closing Date, the sum of the following values for each Contributed Property of such Contributor on such Closing Date: (i) the net asset value of such Contributed Property, (as shown in the column labeled “Market Value Equity” on Schedule 1.1), multiplied by (ii) the Contribution Percentage of such Contributor in such Contributed Property, subject to adjustment as provided in Section 1.1(b), (c) and (d).

          (b) Adjustment for Debt. At each Closing, with respect to each Contributor and each Company Interest in a Contributed Company being contributed by it on such Closing, if the aggregate principal amount of indebtedness, and all accrued and unpaid interest, owed by the Contributed Company or otherwise encumbering the Contributed Property owned by such Contributed Company exceeds as of the Prorations Date the estimated amount of Assumed Debt (as shown in the columns labeled “Mortgage Balance at 2/29/08” and “Mezzanine Financing at 2/29/08” on Schedule 1.1) for such Contributed Property, then the Equity Value of such Contributor will be reduced by the product of (x) the amount of such excess and (y) the Contribution Percentage of such Contributor in the Contributed Company; and (ii) if the estimated amount of Assumed Debt (as shown in the columns labeled “Mortgage Balance at 2/29/08” and “Mezzanine Financing at 2/29/08” on Schedule 1.1) for such Contributed Property exceeds the aggregate principal amount of indebtedness, and all accrued and unpaid interest, owed by such Contributed Company or otherwise encumbering its Contributed Property on the Prorations Date, then the Equity Value of such Contributor shall be increased by the product of (x) the amount of such excess and (y) the Contribution Percentage of such Contributor in such Contributed Company. On each Closing Date, the increases or reductions in a Contributor’s Equity Value for all Contributed Properties being contributed by it on such Closing Date will be

aggregated, and the net increase or reduction, as applicable, will adjust such Contributor’s Equity Value for purposes of determining the number of Common Units to be issued to it pursuant to Section 1.1(a).

          (c) Adjustment for Cash. It is the intention of the Contributors that Cash of each Contributed Company held on the Prorations Date shall be distributed to the applicable Contributed Companies on or before Closing, and Cash of each Contributed Company held after the Prorations Date shall be contributed to the New Company at Closing without adjustment in any Contributor’s Equity Value. Consequently, each Contributor shall use diligent efforts to distribute Cash held by each of its Contributed Companies as of the Prorations Date on or prior to the Closing Date. If, despite using such diligent efforts, any Cash held by a Contributed Company as of the Prorations Date is not so distributed on or prior to the Closing Date, then the Equity Value of the Contributors of such Contributed Company will increase, pro rata in proportion to their respective Contribution Percentages. Each Contributor is hereby prohibited from distributing any Cash of a Contributed Company held after the Prorations Date following the delivery of a Closing Notice in which it is anticipated that the Company Interests in the applicable Contributed Companies will be contributed at Closing; and in that case any Cash so distributed in excess of Cash held by the Contributed Company as of the Prorations Date will reduce the Equity Value of the Contributors of such Contributed Company, pro rata in proportion to their respective Contribution Percentages.

          (d) Adjustment for Net Prorations. At each Closing, the net proration amount for each Contributed Property, computed pursuant to Section 4.11, will adjust the Equity Value of each Contributor contributing a Company Interest (directly or indirectly) in such Contributed Property, pro rata, in proportion to their respective Contribution Percentages. If such net proration amount is a positive credit in favor of the Contributors of such Contributed Property, such adjustment will increase the Equity Value of such Contributors; and if such net proration amount is a negative debit owed to the New Company by such Contributors of such Contributed Property, such adjustment will reduce the Equity Value of such Contributors. On each Closing Date, the increases or reductions in a Contributor’s Equity Value for all Contributed Properties being contributed by it on such Closing Date under this Section 1.1(d) will be aggregated, and the net increase or reduction, as applicable, will adjust such Contributor’s Equity Value for purposes of determining the number of Common Units to be issued to it pursuant to Section 1.1(a).

          (e) The provisions of this Section 1.1 shall survive each Closing.

     1.2 Certain Changes in the Contribution Transactions.

          (a) Northland Restructuring. Notwithstanding anything herein to the contrary, Northland Portfolio may restructure its contribution of the Northland Portfolio Company Interests to the New Company on any basis so long as the restructuring has the same overall economic effect as the contributions and other transactions otherwise contemplated by this Agreement (the “Northland Restructuring”). Tarragon shall have the right to review and approve the Northland Restructuring, which approval shall not be unreasonably withheld, conditioned or delayed; provided, however, that such approval may be withheld if, in the reasonable, good faith

business judgment of Tarragon, the Northland Restructuring will have a material adverse tax or other economic consequence for the New Company or any Tarragon Contributor.

          (b) Tarragon Restructuring. Tarragon shall complete the Tarragon Restructuring on or before the applicable Closing Date in which such Tarragon Company Interests are to be contributed to the New Company, in whole, or with respect to a Closing at which less than all of the Tarragon Company Interests are being contributed to the New Company, in respect of the Tarragon Company Interests being contributed at such Closing. Tarragon shall have the right to change the Tarragon Restructuring from time to time so long as the Tarragon Restructuring has the same overall economic effect as the contributions and other transactions otherwise contemplated by this Agreement, subject Northland’s right to review and approve the Tarragon Restructuring, which approval shall not be unreasonably withheld, conditioned or delayed; provided, however, that such approval may be withheld if, in the reasonable, good faith business judgment of Northland, such change in the Tarragon Restructuring will have a material adverse tax or other economic consequence for the New Company or any Northland Contributor.

          (c) Tarragon SPE Sub. Tarragon Corporation may at any time form a special-purpose wholly owned subsidiary for the purpose of holding the Common Units issuable to it by the New Company hereunder (the “Tarragon SPE”), and thereafter, the obligations of Tarragon Corporation hereunder may be performed by Tarragon SPE. Notwithstanding anything herein to the contrary, Tarragon Corporation shall not be relieved of any of its obligations or liabilities under this Agreement by reason of forming such Tarragon SPE or causing such Tarragon SPE to hold Tarragon Corporation’s Common Units.

          (d) Northgate and Bermuda Island. Northland and Tarragon acknowledge and agree that the Properties identified on Schedule 1.1 as Northgate and Bermuda Island are currently the subject of (i) that certain Purchase and Sale Agreement dated as of March 5, 2008 by and between Middletown Tarragon LLC and Northland Fund III (the “Northgate Purchase Agreement”) pursuant to which Middletown Tarragon LLC has agreed to sell and Northland Fund III has agreed to purchase the Northgate property, and (ii) that certain Membership Interest Purchase and Sale Agreement dated as of March 5, 2008 by and between Tarragon Corporation and Northland Fund II (the “Bermuda Island Purchase Agreement”) pursuant to which Tarragon Corporation has agreed to sell and Northland Fund II has agreed to purchase the membership interests in Bermuda Island Tarragon, LLC. Northland and Tarragon further agree that, to the extent either of the closings on Northgate and/or Bermuda Island occur on or prior to the Final Closing Date hereunder, (i) such closed property shall thereafter constitute a “Northland Property” hereunder, other than as provided in Section 3.6 of this Agreement, (ii) Middletown Tarragon LLC will constitute a “Northland Company” hereunder, other than as provided in Section 3.6 of this Agreement, (iii) the membership interests in such additional Northland Company shall constitute “Northland Company Interests” hereunder to be contributed to the New Company on the next Closing, other than as provided in Section 3.6 of this Agreement, and (iv) Northland Fund III and Northland Fund II will receive the Equity Value attributed to such Property as provided in Schedule 1.1., subject to adjustment as provided herein.

          (e) The provisions of this Section 1.2 shall survive each Closing.

     1.3 Closing.

          (a) The initial closing of the transactions contemplated under this Agreement (the “First Closing”) will take place as promptly as possible but in no event later than the first (1^st) Business Day of the first month immediately following the month in which the Tarragon GE Consent and the Northland 2/3s Consent are both obtained (the “First Closing Date”).

          (b) To the extent that fewer than all of the Company Interests have been contributed to the New Company on the First Closing Date, then subsequent closings (together with the First Closing, each a “Closing”) will occur on the first (1^st) Business Day of each month immediately following the month in which either the Northland Contributing Group or the Tarragon Contributing Group delivers to the other party written notice (each a “Closing Notice”) that its Contributing Group has received additional Lender Consents and is prepared to satisfy the Closing Conditions applicable to its Contributing Group at Closing as to one or more Properties and the related Company Interests not previously contributed (together with the First Closing Date, each a “Closing Date”). On each Closing Date, each Contributing Group will contribute to the New Company all of the Company Interests with respect to which (and to the extent not previously contributed) its Closing Conditions have been satisfied or waived by the other Contributing Group. Notwithstanding anything in the foregoing to the contrary, if either Contributing Group believes or has knowledge that the other Contributing Group has received additional Lender Consents, then a Closing Notice may be sent by either of the Contributing Groups hereunder.

If on the Final Closing Date, fewer than all of the Company Interests have been contributed to the New Company, then, other than those Company Interests that have not been contributed to the New Company as a result of a breach or default hereunder, with respect to which the non-breaching and/or non-defaulting parties shall retain any and all rights and remedies related thereto under this Agreement, the remaining uncontributed Company Interests, Companies and Properties shall not be contributed to the New Company, whereupon this Agreement shall be deemed to have been terminated as to such Company Interests, Companies and Properties (but not as to any other Company Interests, Companies or Properties) and the parties hereto shall have no further obligations or liabilities in respect thereof hereunder, other than with respect to provisions hereof which expressly survive termination.

The Tarragon Contributors with respect to the Tarragon Properties, and the Northland Contributors with respect to the Northland Properties shall bear the cost of all installments or amounts of items which are being apportioned under this Section which became due and payable prior to the Prorations Date; and

          (e) such other items as are customarily apportioned between sellers and purchasers of real properties of a type similar to the Contributed Properties.

     4.2 Commissions. Each Contributor shall bear the cost of all unpaid commissions, fees and other charges due on or prior to the Prorations Date to real estate brokers or other

Persons with respect to any Tenant Lease beginning on or prior to the Prorations Date. The New Company shall be responsible for commissions, fees, or other charges due to real estate brokers or other Persons with respect to Tenant Leases, and any renewals, extensions and expansions thereof, beginning after the Prorations Date. At each Closing, the Equity Value of each Contributor will be reduced by all security deposits which are then unapplied to satisfy tenant obligations under Tenant Leases at such Contributed Property, except to the extent that the applicable Contributed Company holds such security deposit as of the Closing Date.

     4.3 New Tax Rates. If the Proration Date and the Closing Date for a Contributed Property is before a new real property or other applicable tax rate or charge of an Authority is fixed, then the apportionment of such tax or charge at the Closing shall be based upon the tax rate for the immediately preceding fiscal period applied to the latest assessed valuation. Promptly after the new tax rate has been fixed, the apportionment of such tax or charge made at the Closing shall be recalculated and any adjustment to the Equity Value and the number of Common Units issuable to the Contributors in respect of such Contributed Property shall be made promptly after such recalculation.

     4.4 Tenant Leases. If any tenant under a Tenant Lease is in arrears in the payment of rent, or other charges, payments received from such tenant after the applicable Closing shall be applied in the following order of priority: first, to current rents and other sums due the New Company as the current owner of the Property and landlord under the Tenant Lease, and the balance to any delinquent sums owing to the Contributor under the Tenant Lease in respect of the period prior to the Prorations Date. If any payments from a tenant under a Tenant Lease received by the New Company or the Contributor after the Closing are payable to the other by reason of this Section, then the appropriate sum shall be promptly paid to the other by adjustment of the number of Common Units issued to the Contributor.

     4.5 Utility Charges. The apportionment of utility charges shall be made upon the basis of charges shown on the latest available bills of such utilities. The charges shown on such available bills for periods prior to the Prorations Date which have not been paid as of the Closing Date shall be paid by the Contributed Company and credited in favor of the New Company, and for the period from the date of each such last available utility bill to the Prorations Date an apportionment shall be made based on the amount charged for the period covered by such last available bill. Notwithstanding the foregoing, each Contributor with respect to its Contributed Property will use reasonable efforts to cause the respective utility companies to read their meters or fix their charges to the Prorations Date, in which event (i) the Contributed Company shall pay such charges, when billed, to the Prorations Date, and the amount of such payment will be credited at Closing in favor of the New Company, (ii) if the Contributed Company has paid any such charges for any period subsequent to the Prorations Date, such payments shall be credited in favor of the Contributor, and (iii) the Contributed Company shall pay such charges from and after the Prorations Date without any proration hereunder.

     4.6 Utility Deposits. At the Closing, to the extent not otherwise held in the name of the Contributed Company, each Contributor shall assign to the New Company, all deposits or escrows held for the account of such Contributor (or its Affiliate) with respect to its Contributed Property at or by any public utility company in connection with the utility services furnished to the Contributed Property; and in such case the Contributor shall be credited at Closing for the

amount of deposits, or escrows so assigned. Any such deposits or escrows held in the name of a Contributed Company shall be included in the Cash adjustment of Equity Value pursuant to Section 1.1(c).

     4.7 Post-Closing Receipt. If any item covered by this Article cannot be apportioned because the same has not been (or cannot be) fully ascertained on the Closing Date, or if any error has been made with respect to any apportionment, then such item shall be apportioned (or corrected, as applicable) as soon as the same is fully ascertained and any change in Equity Value and the number of Common Units to be issued to a Contributor under Section 1.1 shall be adjusted by issuing to such Contributor additional Common Units, or reducing the number of Common Units issued to such Contributor.

     4.8 Real Estate Tax Refunds. Real estate tax refunds and credits received after a Closing which are attributable to the fiscal tax year during which the Prorations Date falls shall be apportioned between the Contributor, on the one hand, and the New Company, on the other hand, pursuant to this Article. There will be no proration of tax refunds or credits relating to fiscal tax years previous to the one during which the Prorations Date falls.

     4.9 Special Assessments. If, as of the Prorations Date, any of the Properties shall be (or shall have become) subject to a special or local assessment or charge of any kind (whether or not yet a lien), then (to the extent not payable by the tenants) the New Company shall be credited at Closing for any installments thereof due and payable prior to the Prorations Date which have not been paid by the Contributed Company prior to the Prorations Date; provided, however, that any installment thereof attributable to a period from and after the Prorations Date shall be apportioned at the Closing in the same manner as for taxes under Section 4.1(b). The Contributed Company shall be responsible for all installments of such assessment attributable to the period from and after the Prorations Date, without any proration credit in favor of the New Company hereunder.

     4.10 Escrow Balances and Reserves. At each Closing, each Contributor will receive a credit for any escrow balances and reserves held by a lender for the account of a Contributed Company at Closing.

     4.11 Straddle Periods.

          (a) In General. If, for any Income Tax purposes, the Taxable period of any of the Contributed Companies does not terminate on the relevant Prorations Date (any such period, a “Straddle Period”), Income Taxes of such Contributed Company and Income Tax refunds or credits, if any, of such Contributed Company attributable to its ordinary operations during such Straddle Period shall be allocated to (i) the portion of such Straddle Period up to and including the relevant Prorations Date (the “Pre-Closing Straddle Period”), and (ii) the portion of such Straddle Period subsequent to the relevant Prorations Date (the “Post-Closing Straddle Period”) in accordance with this Section 4.11(a). Any Income Taxes and Income Tax refunds of a Contributed Company that are attributable to those transactions that are in the nature of capital transactions shall be allocated under the principles described above based on the relevant Closing Date, instead of the relevant Prorations Date. For purposes of the preceding sentences, Income Taxes and any Income Tax refunds or credits for the Pre-Closing Straddle Period and for the

Post-Closing Straddle Period of a Contributed Company will be determined on the basis of an interim closing of the books as of the close of business on the relevant Prorations Date or Closing Date, as applicable, as if such Straddle Period consisted of one Taxable period ending on the relevant Prorations Date or Closing Date, as applicable, and a Taxable period beginning on the day following the relevant Prorations Date or Closing Date, as applicable.

          (b) Partnerships. For purposes of section 706 of the Code, any item of income and deduction with respect to a Contributed Company that is treated as a partnership for U.S. federal tax purposes shall be allocated under the interim closing of the books method of section 706 of the Code based on the Prorations Date, and any items of such company that are in the nature of capital transactions shall be allocated under the interim closing of the books method under section 706 of the Code based on the Closing Date. The portion of any such items of such Contributed Company attributable to any period to the Contributor (or Contributors) up to and including the relevant Prorations Date or Closing Date, as applicable, shall be allocated to the Contributor (or Contributors) of such Contributed Company, and the portion of such items of such company attributable to the period after the relevant Prorations Date or Closing Date, as applicable, shall be allocated to the New Company.

     4.12 Time Periods. Except as otherwise provided herein, it is the intention of the parties that each Contributor be responsible for all costs and expenses, and obtain the benefit of all income, of its Contributed Companies and Contributed Properties relating to the period up to the Prorations Date, and that the New Company be responsible for such costs and expenses, and obtain the benefit of such income, from and after the Prorations Date, in each case on an accrual basis, but without regard to non-cash items of income or expense, including depreciation and amortization.

     4.13 Adjustment of Equity Value. On each Closing Date, for each Contributor and its Contributed Companies and Contributed Properties, the net amount of all proration credits, without duplication, under this Article 4 in favor of such Contributor shall be netted against the amount of all proration credits, without duplication, under this Article 4 in favor of the New Company, and (i) if the aggregate net proration credit is in favor of such Contributor, then the Equity Value of such Contributor shall be increased by the amount of such net proration credit pursuant to Section 1.1(c) and (ii) if the aggregate net proration credit is in favor of the New Company, then the Equity Value of such Contributor shall be reduced by the amount of such net proration credit pursuant to Section 1.1(c).

     4.14 Survival. This Article 4, and all rights and duties of the New Company and the parties hereunder, shall survive Closing.

ARTICLE 5 — INDEMNIFICATION

     5.1 By Contributors.

          (a) From and after the Closing Date, each Contributor (an “Indemnitor”) agrees severally to indemnify, defend and hold harmless the New Company, each other Contributor, and each such Contributor’s respective subsidiaries, Affiliates, officers, directors, partners, members, managers, security holders, stockholders, employees, representatives and

agents. (collectively, the “Indemnitees”) from and against all Losses which are incurred or suffered by any of them (A) based upon, arising out of, in connection with or by reason of the breach of any of the representations or warranties of such Contributor, (B) based upon, arising out of, in connection with or by reason of any liability or obligation relating to the Contributed Companies or the Contributed Properties contributed, directly or indirectly, by such Contributor of any nature (absolute, accrued, contingent or otherwise) arising or occurring with respect to any period prior to the Prorations Date, (C) based upon, arising out of, in connection with or by reason of the failure of such Contributor to perform or comply, in whole or in part, with any of the covenants or agreements contained herein or in any Related Document to be performed or complied with by such Contributor on or prior to the Closing, and (D) based upon, arising out of, in connection with or by reason of any Income Taxes attributable to a Pre-Closing Tax Period of a Contributed Company. From and after the First Closing Date, if there is Excess Gain allocated to Tarragon Corporation or to Ansonia and recognized prior to December 31, 2018, the New Company shall pay to Tarragon Corporation or Ansonia, as the case may be, an amount equal to the product of such Excess Gain and the tax rate applied with respect to Tarragon Corporation or Ansonia, as applicable, in determining any “Ansonia Tax Amount” or “Tarragon Tax Amount” under the Tax Matters Agreement, such amount to be paid in immediately available funds within thirty (30) days after the filing of the federal income tax return of the New Company for the taxable year in which such Excess Gain was allocated.

          (b) The indemnity against Losses pursuant to Section 5.1(a) shall also include interest on cash disbursements in respect thereof at an annual rate of interest equal to a fixed rate of twelve and one-half percent (12.5%) (the “Reference Rate”), based on actual days elapsed from the later of the date a valid claim is made hereunder or the date of such disbursement until the date the Indemnified Parties are fully reimbursed therefor.

          (c) Notwithstanding the preceding, (i) the Indemnified Parties shall not be entitled to any recovery unless a claim for indemnification is made in accordance with Section 5.3 and within the time period of survival set forth in Article 3 and the person seeking indemnification complies with the procedures set forth in Sections 5.3, 5.4 and 5.5, and (ii) if more than one Indemnitor has an indemnification obligation in respect of the same Contributed Company or Contributed Property, such indemnification obligation shall constitute a several obligation of such Indemnitors, in proportion to their respective Contribution Percentages.

     5.2 Intentionally Omitted.

     5.3 Indemnification Procedure.

          (a) In the event that any Indemnitee shall incur or suffer any Loss in respect of which indemnification may be sought by such party pursuant to the provisions of this Article 5, the Indemnitee shall assert a claim for indemnification by written notice (a “Notice”) to the Indemnitor stating the nature and basis of such claim. In the case of Losses arising by reason of any third party claim, the Notice shall be given within 30 days of the filing of any such claim against the Indemnitee or the determination by Indemnitee that a claim will ripen into a claim for which indemnification will be sought, but the failure of the Indemnitee to give the Notice within such time period shall not relieve the Indemnitor of any liability that the

Indemnitor may have to the Indemnitee except to the extent that the Indemnitor is prejudiced thereby and then only to the extent of such prejudice.

          (b) The Indemnitee shall provide to the Indemnitor on request all information and documentation reasonably necessary to support and verify any Losses which the Indemnitee believes give rise to a claim for indemnification hereunder and shall give the Indemnitor reasonable access to all books, records and personnel in the possession or under the control of the Indemnitee which would have bearing on such claim.

          (c) In the case of third party claims for which indemnification is sought, the Indemnitor shall have the option (x) to conduct any proceedings or negotiations in connection therewith, (y) to take all other steps to settle or defend any such claim (provided that the Indemnitor shall not, without the consent of the Indemnitee, settle any such claim on terms which provide for (A) a criminal sanction or fine, (B) injunctive relief or (C) monetary damages in excess of the amount that the Indemnitor is required to pay hereunder) and (z) to employ counsel, which counsel shall be reasonably acceptable to the Indemnitee, to contest any such claim or liability in the name of the Indemnitee or otherwise. In any event, the Indemnitee shall be entitled to participate at its own expense and by its own counsel in any proceedings relating to any third party claim; provided, however, that if the defendants in any such action or claim include both the Indemnitee and the Indemnitor and the Indemnitee shall have reasonably concluded that there would be a conflict of interest under DR 5-105 of the Code of Professional Responsibility or other applicable federal or state law were the same counsel to represent the Indemnitee and the Indemnitor, the Indemnitee shall be entitled to be represented by separate counsel at the Indemnitor’s expense; provided further, however, that such action or claim shall not be settled without the Indemnitor’s consent, which shall not unreasonably be withheld. The Indemnitor shall, within 30 days of receipt of the Notice, notify the Indemnitee of its intention to assume the defense of such claim. Until the Indemnitee has received notice of the Indemnitor’s election whether to defend any claim, the Indemnitee shall take reasonable steps to defend (but may not settle) such claim. If the Indemnitor shall decline to assume the defense of any such claim, or shall fail to notify the Indemnitee within 30 days after receipt of the Notice of the Indemnitor’s election to defend such claim, the Indemnitee shall defend against such claim (provided that the Indemnitee shall not settle such claim without the consent of the Indemnitor, which consent shall not be unreasonably withheld). The expenses of all proceedings, contests or lawsuits in respect of the claims described in the preceding sentence shall be borne by the Indemnitor but only if the Indemnitor is responsible pursuant hereto to indemnify the Indemnitee in respect of the third party claim and, if applicable, only as required within the limitations set forth in Section 5.1 or Section 5.2 as the case may be. Regardless of which party shall assume the defense of the claim, the parties agree to cooperate fully with one another in connection therewith. In the case of a claim for indemnification made under Section 5.1 or 5.2, (a) if (and to the extent) the Indemnitor is responsible pursuant hereto to indemnify the Indemnitee in respect of the third party claim, then within ten days after the occurrence of a final non-appealable determination with respect to such third party claim (or sooner if required by such determination), the Indemnitor shall pay the Indemnitee (or sooner if required by such determination), in immediately available funds, the amount of any Losses (or such portion thereof as the Indemnitor shall be responsible for pursuant to the provisions hereof and (b) in the event that any Losses incurred by the Indemnitee do not involve payment by the Indemnitee of a third party claim, then, if (and to the extent) the Indemnitor is responsible pursuant hereto to

indemnify the Indemnitee against such Losses, the Indemnitor shall within ten days after agreement on the amount of Losses or the occurrence of a final non-appealable determination of such amount pay to the Indemnitee, in immediately available funds, the amount of such Losses (or such portion thereof as the Indemnitor shall be responsible for pursuant to the provisions hereof).

     5.4 Cooperation in Defense. Each party indemnified under any indemnity contained in this Agreement shall cooperate in all reasonable respects in the defense of the third-party claim pursuant to which the indemnifying party is alleged to have liability.

     5.5 Direct or Derivative Claims. With respect to any indemnified Loss which has been suffered (directly or indirectly) both by the New Company and by a Contributor, the Contributor shall have the right to require, by written demand upon the Board of Managers of the New Company, that the claim for such indemnified Loss be brought by the New Company, and if the Board of Managers does not bring such claim and prosecute such claim in accordance with the directions of such Contributor within fifteen (15) days, then such Contributor may bring such claim on its own behalf, in which case such Contributor will be deemed to have suffered a Loss equal to its pro rata share of the Loss suffered by the New Company, based on its proportionate ownership of the Common Units of the New Company as of the final Closing. Nothing in this Section 5.5 shall prohibit a Contributor from bringing a direct claim for Loss at any time, regardless whether the New Company has also suffered a Loss or brought a claim in respect of the same underlying matter; provided, however, that any recovery by the New Company in respect of such a claim shall be reduced by the amount of any direct recovery by a Contributor in respect of the same underlying matter, and such Contributor shall not participate through the New Company in any such additional recovery by the New Company.

     5.6 General. The parties shall use reasonable efforts to mitigate any indemnified Loss in connection with this Agreement. The parties shall also use reasonable efforts to structure any indemnity payment in a manner such that the Indemnitor will obtain any deduction or other tax benefit arising from having made such indemnification payment in order to avoid any duplication of after-tax benefit to the Indemnitee. The amount of indemnified Loss incurred by the Indemnitee shall be reduced by the amount of any insurance benefit received by the Indemnitee or by the New Company in respect of such Loss. Any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement. No matter shall be the subject of an indemnification claim hereunder to the extent that the Indemnitee has otherwise been compensated therefor, including through the prorations or other adjustments to Equity Value under Section 1.1.

     5.7 Survival. This Article 5 shall survive each Closing.

ARTICLE 6 — DEFAULTS AND REMEDIES

     6.1 Defaults. In the event of (i) a failure by a party to perform any of its material obligations hereunder, which failure continues for more than fifteen (15) days following receipt of notice thereof from the other party or (ii) the inaccuracy of any representation or warranty made by a party in this Agreement or in any document delivered pursuant to the terms hereof to

the extent such inaccuracy of such representation or warranty results in or constitutes a Material Adverse Effect, then the other party shall have the right to terminate its obligation to consummate the transaction contemplated by this Agreement (or any remaining portion thereof) by delivery of notice thereof to the other party. Subject to the terms of this Article below, upon any such termination or any termination otherwise permitted under this Agreement, all rights and obligations of the parties under this Agreement, other than those that by their terms survive termination, shall terminate without recourse, and this Agreement shall be of no further force or effect.

     6.2 Remedies of Northland.

     In addition to its right to terminate this Agreement, in the event of a failure any Tarragon Contributor to perform its obligations to close on the contribution transactions under this Agreement at any Closing, which failure continues for more than fifteen (15) days following receipt of notice thereof, then Northland shall have the right to (i) seek specific performance of the terms of this Agreement, and (ii) to the extent a specific performance remedy is not available, to pursue any other remedy it may have at law or in equity in connection with such failure. Notwithstanding anything in the foregoing to the contrary, in the event that Northland elects to seek damages for any failure, breach or default hereunder, then the parties agree that Northland’s recovery for any and all such defaults shall not exceed $5,000,000 in the aggregate against all Tarragon Contributors (and such $5,000,000 limitation will be applied severally to limit the liability of each Tarragon Contributor, pro rata on the basis of their respective Equity Values); provided, however, that in the event that any such failure, breach or default is the result of the willful failure, breach, default, misconduct or omission on the part of a Tarragon Contributor, then the $5,000,000 aggregate limitation on damages shall not be applicable to, and Northland shall be permitted to recover any and all damages caused by such failure, breach or default on the party of, such Tarragon Contributor. As a condition precedent to Northland exercising any right it may have to bring an action for specific performance hereunder, Northland must commence such an action within ninety (90) days after Northland first becomes aware of Tarragon’s default. Northland agrees that its failure to timely commence such an action for specific performance within such ninety (90) day period shall be deemed a waiver by it of its right to commence an action for specific performance as well as a waiver by it of any right it may have to file or record a notice of lis pendens or notice of pendency of action or similar notice against any portion of the applicable Tarragon Property.

     6.3 Remedies of Tarragon.

     In addition to its right to terminate this Agreement, in the event of a failure any Northland Contributor to perform its obligations to close on the contribution transactions under this Agreement at any Closing, which failure continues for more than fifteen (15) days following receipt of notice thereof, then Tarragon shall have the right to (i) seek specific performance of the terms of this Agreement, and (ii) to the extent a specific performance remedy is not available, to pursue any other remedy it may have at law or in equity in connection with such failure. Notwithstanding anything in the foregoing to the contrary, in the event that Tarragon elects to seek damages for any failure, breach or default hereunder, then the parties agree that Tarragon’s recovery for any and all such defaults shall not exceed $5,000,000 in the aggregate against all Northland Contributors (and such $5,000,000 limitation will be applied severally to limit the

liability of each Northland Contributor, pro rata on the basis of their respective Equity Values); provided, however, that in the event that any such failure, breach or default is the result of the willful failure, breach, default, misconduct or omission on the part of a Northland Contributor, then the $5,000,000 aggregate limitation on damages shall not be applicable to, and Tarragon shall be permitted to recover any and all damages caused by such failure, breach or default on the part of, such Northland Contributor. As a condition precedent to Tarragon exercising any right it may have to bring an action for specific performance hereunder, Tarragon must commence such an action within ninety (90) days after Tarragon first becomes aware of Northland’s default. Tarragon agrees that its failure to timely commence such an action for specific performance within such ninety (90) day period shall be deemed a waiver by it of its right to commence an action for specific performance as well as a waiver by it of any right it may have to file or record a notice of lis pendens or notice of pendency of action or similar notice against any portion of the applicable Northland Property.

     6.4 Sole and Exclusive Remedies. The remedies set forth in this Article 6, together with those set forth in Section 3.5 and Article 5 comprise the sole and exclusive remedies of a party hereto (or any person claiming by, through or under such party, including any Indemnitee) in respect of any breach of the representations, warranties or covenants set forth in this Agreement or in any Related Document.

ARTICLE 7 — FUTURE OPERATIONS

     7.1 Operations. Except as otherwise expressly permitted by this Agreement (including pursuant to the Tarragon Restructuring or the Northland Restructuring), each Tarragon Contributor with respect to the Tarragon Properties and Tarragon Companies, and each Northland Contributor with respect to the Northland Properties and the Northland Companies, hereby agrees and covenants with respect to the Property and/or Company Interests that have not already been contributed to the New Company, that from the date hereof through each Closing or the earlier termination of this Agreement:

          (a) Neither Tarragon nor Northland, and no Tarragon Company or Northland Company, shall sell, encumber, further pledge, or otherwise transfer or dispose of all or any part of the Tarragon Company Interests, the Northland Company Interests, the Tarragon Property or the Northland Property, or amend, modify or terminate any Tarragon Operating Agreements or Northland Operating Agreements, without the prior consent of the other party hereto.

          (b) Neither Tarragon nor Northland, and no Tarragon Company or Northland Company, shall enter into, extend, renew, replace or modify any contract, agreement or other arrangement with regard to the Tarragon Property or the Northland Property which will be binding on the New Company, the Tarragon Property or the Northland Property after Closing unless such contract, agreement or other arrangement (as so extended, renewed, replaced or modified) can be terminated by the New Company without penalty or payment of any fee on not more than thirty (30) days notice.

          (c) Neither Tarragon or Northland, and no Tarragon Company or Northland Company, shall initiate or consent to any zoning changes, liens or encumbrances of or against the Tarragon Property or the Northland Property without the prior written consent of the other

party, and shall give the other party copies of all notices received by Tarragon or Northland with respect to any such matters.

          (d) Each of Tarragon, Northland, the Tarragon Companies and the Northland Companies shall continue to manage, lease, market and operate the Tarragon Property and the Northland Property in the ordinary course of business in accordance with the management, leasing and operation standards and practices currently in effect at the Tarragon Property and the Northland Property, as applicable, and shall continue to perform all of its obligations with respect to the Tarragon Leases, Northland Leases, Tarragon Contracts and Northland Contracts, as applicable.

          (e) Each of Tarragon, Northland, the Tarragon Companies and the Northland Companies shall repair and maintain the Tarragon Property and the Northland Property in its present condition, normal wear and tear excluded and subject to Article 8, and continue to maintain the insurance policies currently in effect with respect to any of the foregoing or enter into new policies with substantially the same coverage.

          (f) Neither Tarragon and Northland shall, or permit any Tarragon Company or Northland Company, to enter into any new Tenant Lease or amend any existing Tenant Lease, without the other party’s consent, not to be unreasonably withheld, conditioned or delayed, unless (i) same is on the current standard lease form for the applicable Property; (ii) provides for payment of monthly rent at the rates currently in effect for the applicable Property; (iii) is for a term of no less than one year nor more than 15 months; and (iv) does not provide any “free rent” or other concessions beyond those currently offered and consistent with current practice with respect to the applicable Property and only to the extent such “free rent” or other concessions are not so-called “back-ended”.

          (g) Each of Tarragon and Northland will keep all debt service payments and other payments owned in connection with the Tarragon Assumed Debt and the Northland Assumed Debt, as applicable, current on the Tarragon Property and the Northland Property and will not permit or suffer to exist any default under any Tarragon Debt Instrument or Northland Debt Instrument.

     7.2 Notification of Certain Matters. Tarragon shall give prompt notice to Northland, and Northland shall give prompt notice to Tarragon, of (a) the occurrence, or failure to occur, of any event that causes any representation or warranty herein or in any document relating to the transaction contemplated in this Agreement hereunder to be untrue or inaccurate in any material respect at any time from the date of this Agreement to each Closing Date, and b) any failure Tarragon, on the one hand, or Northland, on the other hand, to comply with or satisfy, in any material respect, any covenant, condition or agreement to be complied with or satisfied by it under any document relating to the transaction contemplated in this Agreement.

ARTICLE 8 — RISK OF LOSS

     8.1 Casualty. Each Contributor assumes all risks for damage to or injury occurring to its Contributed Property by fire, storm, accident, or any other casualty or cause (a “Casualty”) until the applicable Closing with respect to the Contributed Property has been completed.

Immediately after a Contributor has received notice of the occurrence of any Casualty between the date hereof and the applicable Closing, such Contributor shall give the other Contributors written notice thereof (a “Casualty Notice”), which Casualty Notice shall state the type, location and amount of damage to such Property, the portions of such Property affected by the Casualty and such Contributor’s good faith estimate of the loss of gross rental income that the Property will suffer while such Casualty is being repaired. If the affected Property is reasonably expected to suffer as a result of such Casualty a loss of gross rental income (taking into account any business interruption insurance proceeds) in excess of 20% of the Property’s pro forma gross rental income for the twelve (12) month period following the Casualty (a “Material Casualty”), then the Contributing Group receiving such Casualty Notice shall have the right, exercisable for a period of ten (10) Business days after its receipt of such Casualty Notice, to elect to terminate this Agreement with respect to such Property and any Company that owns, directly or indirectly, only such Property (the parties agreeing to cooperate in good faith to restructure the ownership of any Company that owns both direct or indirect interests in such Property and any direct or indirect interest in another Property so as to eliminate such overlapping interests). If this Agreement is terminated with respect to such Property and any such Company, none of the parties shall have any further right or obligation hereunder in respect of such Property or such Company, except as to provisions which by their terms survive termination of this Agreement, but this Agreement shall remain in effect with respect to all other Properties and Companies. If the Contributing Group receiving such Casualty Notice does not elect to terminate this Agreement as to such Property and any such Company, or if such Casualty is not a Material Casualty, then such Property shall remain subject to the terms of this Agreement and shall be contributed to the New Company by its Contributor, along with any insurance proceeds paid on account of such Casualty (including rental interruption insurance, but only for the period from and after the Prorations Date) not expended to repair the property prior to the Closing Date, and the New Company shall receive a credit against such Contributor’s Equity Value in the amount of any deductible payable by such Contributor or the applicable Contributed Company in connection with casualty coverage.

     8.2 Condemnation. If, prior to Closing, all or any significant portion of any Property is taken, or rendered unusable for its current purpose or reasonably inaccessible by eminent domain (or is the subject of a pending or contemplated taking which has not been consummated), (a “Condemnation”), then, upon receipt of written notice of such action from any Authority, the Contributor of such Property shall immediately give the other Contributors written notice thereof (a “Condemnation Notice”), which Condemnation Notice shall state the nature of such Condemnation, the portions of such Property affected by the Condemnation and such Contributor’s good faith estimate of the loss of gross rental income that the Property will suffer as a result of such Condemnation. If the affected Property is reasonably expected to suffer as a result of such Condemnation a loss of gross rental income in excess of 20% of the Property’s pro forma gross rental income for the twelve (12) month period following the Condemnation (a “Material Condemnation”), then the Contributing Group receiving such Condemnation Notice shall have the right, exercisable for a period of ten (10) Business days after its receipt of such Condemnation Notice, to elect to terminate this Agreement with respect to such Property and any Company that owns, directly or indirectly, only such Property (the parties agreeing to cooperate in good faith to restructure the ownership of any Company that owns both direct or indirect interests in such Property and any direct or indirect interest in another Property so as to eliminate such overlapping interests). If this Agreement is terminated with respect to such Property and

any such Company, none of the parties shall have any further right or obligation hereunder in respect of such Property or such Company, except as to provisions which by their terms survive termination of this Agreement, but this Agreement shall remain in effect with respect to all other Properties. If the Contributing Group receiving such Condemnation Notice does not elect to terminate this Agreement as to such Property and any such Company, or if such Condemnation is not a Material Condemnation, then such Property shall remain subject to the terms of this Agreement and shall be contributed to the New Company by its Contributor, along with any and all rights to the condemnation award in respect of such Condemnation (other than any portion thereof relating to loss of rental income for the period prior to the Prorations Date).

     8.3 Portfolio Termination Right. Notwithstanding anything to the contrary contained in Section 8.1 or 8.2, in the event that the Contributed Properties of either Contributing Group have suffered Material Casualties or Material Condemnations resulting in the termination of this Agreement with respect to such Properties representing more that 20% of the gross asset value (as such gross asset value is set forth on Schedule 1.1) of all the Properties of such Contributing Group, then the other Contributing Group shall have the right to terminate this Agreement by delivery of written notice thereof to the other parties, whereupon this Agreement shall terminate as to all Companies and Properties not contributed at a previous Closing, and the parties shall cease to have any further obligations or liabilities hereunder in respect thereof, other than obligations which by their terms expressly survive termination of this Agreement.

ARTICLE 9 — MISCELLANEOUS

     9.1 Brokers. Each party to this Agreement represents and warrants that neither it nor any of its Affiliates has had any contact or dealings regarding the Properties, or any communication in connection with the subject matter of the transactions contemplated by this Agreement, through any real estate broker or other person who can claim a right to a commission or finder’s fee in connection with therewith. In the event that any other broker or finder claims a commission or finder’s fee based upon any contact, dealings or communication, the party through whom or through whose Affiliate such other broker or finder makes its claim shall be responsible for such commission or fee and all costs and expenses (including, without limitation, reasonable attorneys’ fees and disbursements) incurred by the other party and its Affiliates in defending against the same. The party through whom or through whose Affiliate such other broker or finder makes a claim shall hold harmless, indemnify and defend the other party hereto, its successors and assigns, agents, employees, officers and directors, and the Property from and against any and all Losses, arising out of, based on, or incurred as a result of such claim.

It is agreed that no obligation under this Agreement which by its terms is to be performed or continue to be performed after Closing and no provision of this Agreement which is expressly to survive Closing shall merge upon Closing, but shall survive Closing.

     9.7 Governing Law. The laws of the State of New York shall govern the validity, enforcement and interpretation of this Agreement.

Notwithstanding the foregoing, if the same is permitted pursuant to applicable Laws, either party shall be entitled to record a notice of lis pendens if such party is entitled to seek (and is actually seeking) specific performance of this Agreement by the other party in accordance with the terms of Article 6 hereof.
