2. FORMATION OF THE COMPANY; CONTRIBUTIONS; CLOSING PROCEDURES

2.1 Contribution Procedures. When the conditions to Closing (as defined in Section 6.1) set forth in Sections 5.1 and 5.2 have been satisfied or waived by the party for whose benefit the conditions are included, the following shall occur:

(a) Formation of Company. The parties shall execute and deliver the Limited Partnership Agreement of the Company in the form of Exhibit F (the “Partnership Agreement”). Liberty hereby designates Liberty Washington Venture, LLC (the “LLC”) to receive the general partnership interests in the Company to which Liberty is entitled by reason of its contributions hereunder. The LLC has filed or caused to be filed the certificate of limited partnership for the Company with the Secretary of State of the Sate of Delaware on September 21, 2007.

(b) Capital Contributions.

(i) On the day prior to the Closing Date, subject to the adjustments provided for herein, in consideration of the terms and conditions set forth herein,

NYSCRF shall contribute cash to the Company an amount (herein referred to as the “Contribution Amount”) equal to $415,063,748.00.

(ii) On the Closing Date, the parties shall undertake the Additional Closing Procedures described on Schedule 2.1(b)(ii) attached hereto, in the order set forth therein. The transactions described in Schedule 2.1(b)(ii) shall result in Liberty making a capital contribution to the Company on behalf of the LLC in the aggregate amount of $138,354,583.00.

Notwithstanding the foregoing, in the event that lender approval is not obtained for the assumption of any of the Assumed Financing (as defined in Section 3.4) prior to the contribution or sale of the applicable Entity to the Company, the then-existing management agreement for such Entity (the “Existing Management Agreement”) shall remain in place and effective until such approval is obtained or such Assumed Financing is paid off, defeased or refinanced; provided, however, that as between the Manager and the “Owner” under such Existing Management Agreement, the fees and obligations set forth in the form of Management and Leasing Agreement attached hereto as Exhibit G shall control.

2.2 Tax Treatment. Upon completion of the events described in Section 2.1, except as otherwise provided herein, the transaction contemplated hereby will be treated, for federal income tax purposes, as a contribution to the Company of a twenty-five percent (25%) undivided interest in the Contributed Interests in exchange for an interest in the Company and a sale to the Company of a seventy-five percent (75%) undivided interest in the Contributed Interests in exchange for an amount realized equal to the amount of the Merger Loan (and all other indebtedness or liabilities to which the Contributed Interests are subject or treated as subject for tax purposes).

3. PRE-CLOSING MATTERS

3.2 Additional Service Contracts. From and after the date hereof, and continuing until Closing or the earlier termination of this Agreement (in whole or, with respect to any Interest being terminated pursuant to this Agreement, in part), Liberty shall not enter into any new Service Contracts with respect to the Property without the prior consent of NYSCRF, which consent shall not be unreasonably withheld, conditioned or delayed.

3.3 Additional Tenant Leases. From and after the date hereof, and continuing until Closing or the earlier termination of this Agreement (in whole or, with respect to any Contributed Interest being terminated pursuant to this Agreement, in part), Liberty shall not enter into any new Tenant Leases with respect to the Property without the prior consent of NYSCRF, which consent shall not be unreasonably withheld, conditioned or delayed.

3.4 Existing Loans. Nine (9) of the Parcels are currently encumbered by mortgage loans, and one (1) Contributed Entity currently maintains a secured revolving line of credit, each as more particularly shown on Schedule 3.4 attached hereto (collectively, the “Existing Loans"). Liberty intends to undertake the following actions with respect to the Existing Loans at

or before Closing, all at the sole cost and expense of the Company: (i) the construction loan currently encumbering ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇ will be repaid in full; (ii) the line of credit will be repaid in full; (iii) the mortgage loans currently encumbering Lakeside I & II and WillowWood III & IV will be defeased in accordance with the procedures described in Schedule 2.1(b)(ii); and (iv) the remaining Existing Loans will remain in place and will be “assumed” by the Company.

4. REPRESENTATIONS, WARRANTIES AND COVENANTS

4.1 Liberty’s Representations and Warranties. Liberty represents and warrants to NYSCRF (and to the Company, as of the Closing Date) as follows (which representations and warranties shall be true and correct as of the date hereof and as of the Closing):

(a) Entities.

(i) Each Entity is a duly formed, validly existing limited liability company or limited partnership organized under the laws of the State of Delaware and is duly qualified or registered to do business in the Commonwealth of Virginia or the District of Columbia, as applicable based upon the location of the Parcel owned by such Entity, if any.

(ii) The limited liability company agreement or partnership agreement, whichever is applicable (the “Operating Agreements”), of each Entity is in full force and effect, has not been modified, supplemented, amended or terminated and, together with the applicable Certificate of Formation or Certificate of Limited Partnership, constitutes the sole agreement and understanding (written or oral) among the parties thereto with respect to the applicable Entity. A true and correct copy of the Operating Agreement of each Entity has been delivered to NYSCRF.

(iii) On the Closing Date, Liberty will be the only beneficial and legal owner of the Contributed Interests, free and clear of all liens, security interests, pledges, assignments, claims, options, encumbrances, charges, commitments, and equitable interests or rights of others, of any kind whatsoever, other than the Assumed Financing and the Merger Loan.

(iv) Neither Liberty nor any Entity is the subject of any bankruptcy or other insolvency proceeding.

(v) The Entities have no assets other than their direct or indirect interest in the Property as shown on Exhibit A, and, where applicable, direct or indirect ownership interests in Entities that own the Property.

(vii) No Entity employs employees who manage, maintain or service the Property and whom the Company would be obligated to employ subsequent to Closing. There are no collective bargaining agreements or other similar contracts or agreements with any labor union or bargaining unit respecting the Property or the Entities.

(viii) None of the Entities is a “foreign person” within the meaning of Sections 1445 and 7701 the Internal Revenue Code of 1986, as amended (hereinafter, the “Code”).

(ix) The Entities are not delinquent in filing any tax returns which are required to have been filed by them. The Entities have no outstanding liability for any Taxes (as hereinafter defined), with the exception of Tax for the current tax year that are to be allocated between Seller and Buyer as set forth in Section 7.1(f). “Tax” means any federal, state, county, provincial, local or foreign income, gross receipts, sales, use, ad valorem, employment, severance, transfer, gains, profits, excise, franchise, property, capital stock, premium, minimum and alternative minimum or other taxes, fees, levies, duties, assessments or charges of any kind or nature whatsoever imposed by any government, any governmental entity, department, commission, board, agency or instrumentality, and any court, tribunal or judicial body, in each case whether federal, state, county, provincial, local or foreign (“Governmental Authority”), whether such Tax is payable directly or by withholding, together with any interest, penalties (civil or criminal), additions to or additional amounts imposed by, any Governmental Authority with respect thereto.

(b) Property.

(i) Title. Each Entity or its subsidiary that is the fee owner of the Parcel in question, holds or will hold as of Closing, a title insurance policy insuring fee simple ownership of the Land and the Improvements for its respective Parcel. To Liberty’s knowledge, the Entities do not own or lease any personal property in connection with the Land and Improvements.

(ii) Litigation. There is no pending nor, to Liberty’s knowledge, threatened litigation or administrative proceedings that, if resolved adversely to Liberty or any Entity would adversely affect title to the Property or any part thereof or the ability of Liberty to perform any of its obligations hereunder or the use of the Property by the Company as it is presently being used or otherwise materially and adversely affect the Property, except as set forth on Schedule 4.1(b)(ii) (the “Existing Litigation”).

(iii) Notice of Liens. Liberty has not received written notice of the intention of any governmental authority to file or impose any liens (other than statutory liens for real estate taxes not yet due and payable) or special assessments against any of the Property, nor, to Liberty’s knowledge, do there currently exist any facts or circumstances that would allow any governmental authority the right to file or impose such liens or assessments.

(iv) Schedule of Leases; Rent Roll; Tenant Leases. To Liberty’s knowledge, the Schedule of Lease Documents (the “Schedule of Leases”) provided to NYSCRF pursuant to Section 3.1 hereof is a complete and correct list of all Tenant Leases and amendments thereto in effect as of the date of this Agreement. To Liberty’s knowledge, the rent roll provided to NYSCRF pursuant to Section 3.1 hereof (the “Rent Roll”) sets forth with respect to each of the Tenant Leases in effect on the date hereof (i) the square footage of the space covered thereby, (ii) the expiration date of the term thereof, (iii) the rents and other charges payable thereunder, (iv) the amount of the security deposit thereunder, if any, and (v) any brokerage or leasing fees due and payable thereunder. To Liberty’s knowledge, no Tenant Lease has been modified, altered or amended in any respect except as set forth in the Schedule of

Leases. To Liberty’s knowledge, there are no leases, tenancies or other rights of occupancy or use for any portion of the Property other than pursuant to Tenant Leases, copies of which have been delivered to NYSCRF.

(v) Encumbrances on Tenant Leases. To Liberty’s knowledge, subject to the Assumed Financing, none of the Tenant Leases and none of the rents or other amounts payable thereunder has been assigned, pledged or encumbered by Liberty, except for any assignment, pledge or encumbrance that Liberty will cause to be terminated or released at or prior to Closing.

(vi) Brokerage or Leasing Commissions. Except as disclosed on the Rent Roll, to Liberty’s knowledge, no brokerage or leasing commissions or other compensations are due or payable by Liberty to any person, firm, corporation, partnership, limited liability company or other entity (each a “Person”) with respect to or on account of the current term of any of the Tenant Leases. Except as disclosed in the Rent Roll or set forth in the Tenant Leases, to Liberty’s knowledge, no brokerage or leasing commissions or other compensations are due or payable by the landlord on any extension or expansion of any Tenant Lease.

(vii) Obligations to Tenants under Tenant Leases. Except as set forth on Schedule 4.1(b)(vii) attached hereto, with respect to tenants in occupancy under Tenant Leases as of the Closing Date, to Liberty’s knowledge, there are no unperformed obligations to provide any tenant under any Tenant Lease with any painting, repair, alteration, carpeting, appliance or any other equipment or work of any kind, under any Tenant Lease or under any other oral or written agreement whatsoever that would excuse such tenant from accepting its Premises under the terms of its lease, except for obligations (i) that will be performed and paid for by Liberty before the Closing or (ii) to complete any portion of the Premises covered by the Tenant Lease not yet occupied by the tenant thereunder and not required to be completed under the terms of the Tenant Lease as of the Closing Date or pursuant to renewal rights under Tenant Leases.

(viii) Enforceability of Tenant Leases. To Liberty’s knowledge, each of the Tenant Leases is valid and subsisting and in full force and effect in accordance with its terms, provisions and conditions and constitutes the legal, valid, binding and enforceable obligation of the tenant thereunder, subject to laws applicable generally to creditor’s rights. As of the date of this Agreement, neither Liberty nor, to the knowledge of Liberty, the tenant is in material default thereunder. To Liberty’s knowledge, as of the date of this Agreement, (i) each tenant under a Tenant Lease scheduled to be in possession as of the date hereof has accepted the premises covered by its Tenant Lease and is in possession of such premises in accordance with its Tenant Lease, and (ii) all initial installation work, if any, required of Liberty in order for the tenant to accept the premises then in actual occupancy by a tenant under the terms of its lease has been fully performed, paid for and accepted by each such tenant. To Liberty’s knowledge, no tenant under a Tenant Lease that has been signed as of the date hereof has any pending litigation, offsets or counterclaims against Liberty that, if successfully asserted, would reduce the rent payable thereunder or result in the cancellation or termination thereof. No tenant has given any written notice to Liberty of such tenant’s intention of instituting litigation with respect to any Tenant Lease or terminating its tenancy. Each of the representations and warranties set forth in this Section 4.1(viii) is subject to the matters disclosed on Schedule 4.1(viii) attached hereto.

(ix) Agreements to Acquire or Possess the Property. Except as set forth in the Tenant Leases, to Liberty’s knowledge, no tenant or other occupant under the Tenant Leases and no other Person (other than, pursuant to this Agreement, the Company) has any right or option to acquire any fee or leasehold ownership interest in the Property, or any part thereof, from Liberty or any Entity. Neither Liberty nor, to Liberty’s knowledge, any Entity has entered

into any agreement with any Person granting the right to possess the Property, other than (i) tenants in possession pursuant to the Tenant Leases described in the Schedule of Leases, (ii) tenants under Tenant Leases entered into by the Entities after the date hereof in accordance with Section 3.3; or (iii) matters of public record.

(x) Defects; Violations; Condemnation Proceedings. With respect to the Property, neither Liberty nor, to Liberty’s knowledge, any Entity has received any written notice from any insurance company, governmental agency or any other Person of (i) any condition, defect, or inadequacy affecting the Property that, if not corrected, would result in termination of insurance coverage or materially increase its cost, (ii) any pending or threatened condemnation proceedings, or (iii) any proceedings that could or would reasonably be likely to cause the change or other material modification of the zoning classification or other legal requirements, applicable to the Property or any part thereof which would materially and adversely affect the Property. To Liberty’s knowledge, there does not exist any court order, nor does there exist any restriction or restrictive covenant (save and except matters of public record and all laws, statutes, ordinances and regulations of applicable governmental authorities) or other private or public limitation, that is reasonably likely to materially and adversely affect the use of the Property as presently being operated.

(xi) Mechanic’s Liens. At Closing, except for payments currently due or to become due under existing contracts for tenant improvements under the Tenant Leases in force and effect as of the date hereof and except for any payments currently due or to become due under the construction contracts for the development of the Parcel located at ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇.▇., to Liberty’s knowledge, there will not be any unpaid charges, debts, liabilities, claims or obligations of Liberty or any Entity arising from the construction, occupancy, ownership, use or operation of the Property which could give rise to any mechanics’ or materialmen’s or other statutory liens against any of the Property that will not be paid by Liberty or an Entity at the Closing (or bonded over in a manner reasonably acceptable to NYSCRF and the Title Company and in accordance with the provisions of any applicable statutes or regulations or affirmatively insured against by the Title Company to NYSCRF’s reasonable satisfaction or for which Liberty may be willing to escrow funds, to the reasonable satisfaction of NYSCRF).

(xii) Governmental Requirements. Neither Liberty nor, to Liberty’s knowledge, any Entity has received a written notice from any Governmental Authority asserting a violation of any uncured restrictive covenants, deed restrictions or zoning requirements or other applicable Governmental Requirements (as defined in Section 13.1(a) hereof) affecting the Property.

(xiii) Streets and Highways. Neither Liberty nor, to Liberty’s knowledge, any Entity has received a written notice of any existing plans to widen, modify or realign any street adjoining the Property.

(xiv) Unfulfilled Binding Commitments. No commitments have been made by Liberty nor, to Liberty’s knowledge, any Entity to any Governmental Authority, utility company, school board, church or other religious body, or any homeowners or homeowners’ association, or any other organization, group or individual, relating to the Property (other than with respect to any declaration in place at the Property) that would impose an obligation upon the Company or its successors or assigns to make any contribution or dedications of money or land or to construct, install or maintain any improvements of a public or private nature on or off the Property, except for obligations due under the Tenant Leases and all recorded instruments.

(xv) Service Contracts, Tenant Leases, etc. To Liberty’s knowledge, there are no other contracts (including collective bargaining agreements), other than the Service Contracts, the Tenant Leases and matters of public record, that materially and adversely affect the Property or the operation thereof except as provided to NYSCRF pursuant to Section 3.1.

(i) Existence; Authority. Liberty has been formed as a limited partnership under the laws of the Commonwealth of Pennsylvania and is in good standing under the laws of such commonwealth. The execution and delivery of, and Liberty’s performance under, this Agreement are within Liberty’s powers and have been duly authorized by all requisite action. The Persons executing this Agreement on behalf of Liberty have the authority to do so. This Agreement constitutes the legal, valid and binding obligation of Liberty and is enforceable against Liberty in accordance with its terms, subject to laws applicable generally to creditor’s rights. Except to the extent lender approval for the assumption by the Company of the Assumed Financing is not obtained prior to Closing, performance of this Agreement will not result in any breach of, or constitute any default under, or result in the imposition of any lien or encumbrance upon the Property under, any agreement or other instrument to which Liberty is a party or by which Liberty or the Property is bound. Except as disclosed on Exhibit H hereto, no consent or approval of any Person, Entity or of any Governmental Authority is required with respect to the execution and delivery of this Agreement by Liberty or the consummation by Liberty of the transactions contemplated hereby or the performance by Liberty of its obligations hereunder.

(ii) Foreign Person. Liberty is not a “foreign person” within the meaning of Sections 1445 and 7701 of the Code.

4.2 Delivery of Documents. To Liberty’s knowledge, all of the Leases, Service Contracts and financial information pertaining to the Property (collectively, the “Documents”) submitted by or on behalf of Liberty to NYSCRF hereunder that Liberty or Liberty’s employees or agents prepared shall be true, correct and complete in all material respects. Liberty has no knowledge that any of the Documents submitted by or on behalf of Liberty to NYSCRF hereunder which were prepared by third parties contain material inaccuracies or omissions. The copies of Documents submitted shall be complete and correct copies of the documents in Liberty’s possession.

4.3 Knowledge Defined.

(b) Operation and Management of the Property. From Liberty’s acquisition of the Contributed Interests and until the Closing, Liberty shall cause the Property to be operated and maintained in at least the same quality and manner as Republic operated and maintained the

Property prior to the date hereof. Without the prior written consent of NYSCRF, Liberty will not initiate or permit any zoning reclassification of the Property or seek any variance under existing zoning ordinances applicable to the Property to use or permit the use of the Property in such a manner that would result in such use becoming a nonconforming use under applicable zoning ordinances or other Governmental Requirements. Liberty will not impose any restrictive covenants or encumbrances (other than Tenant Leases) on the Property or execute or file any subdivision plat affecting the Property without the prior written consent of NYSCRF.

(c) Insurance. Liberty hereby agrees that from Liberty’s acquisition of the Contributed Interests and until the Closing, it will maintain, or cause to be maintained, in full force and effect full replacement value and/or all risk fire and extended coverage insurance upon the Property and public liability insurance with respect to damage or injury to persons or property occurring on the Property in such amounts as is maintained by Republic on the date of this Agreement (such amounts to be increased, if necessary, upon further construction).

(d) No Solicitation. Liberty, on behalf of itself, its agents, contractors and representatives, agrees that from the date hereof until the earlier of the Closing or the date that this Agreement is terminated, it will not accept any offers to purchase or otherwise acquire the Entities or the Property from any party other than the Company or NYSCRF and will not market the Entities or the Property to any other parties.

(e) Condemnation; Injury; Damages. Promptly upon obtaining knowledge of the institution of any proceedings for the condemnation of the Property, or any portion thereof, or any other proceedings arising out of injury or damage to the Property, or any portion thereof, Liberty will notify NYSCRF of the pendency of such proceedings.

(f) Governmental Requirements; Litigation. Liberty will advise NYSCRF promptly of any litigation, arbitration or administrative hearing concerning or affecting the Property or the ownership and/or operation thereof of which Liberty has actual knowledge or written notice.

(g) Liens. Except for the liens of the Assumed Financing and liens that Liberty shall be obligated to release at or prior to Closing, Liberty shall not grant, consent or permit the filing of any lien or encumbrance against the Property or any portion thereof subsequent to the date hereof. Liberty will not, without the prior written consent of NYSCRF, sell, lease, exchange, assign, transfer, convey or otherwise dispose of all or any part of the Property or any interest therein, or permit any of the foregoing, except pursuant to Tenant Leases and other leases approved in writing in advance by NYSCRF pursuant to the terms hereof.

(h) Existence. Liberty will continuously maintain Liberty’s existence as a limited partnership. From and after Liberty’s acquisition of the Contributed Interests and until the Closing, Liberty will continuously maintain the Entities’ existence as limited liability companies or limited partnerships, as applicable.

(i) Books and Records. From and after Liberty’s acquisition of the Contributed Interests and until the Closing, Liberty will keep or cause to be kept accurate books and records of the operation of the Property in substantially the same manner as Liberty or its predecessors in interest have maintained such books and records prior to the date of this Agreement, and in which full, true and correct entries shall be made as soon as reasonably practical as to all operations on the Property, and all such books and records shall at all times during reasonable business hours be subject to inspection by NYSCRF and its duly authorized representatives, subject to Republic’s approval.

(j) Tenant Improvements; Leasing Commissions.

7. PRORATIONS

7.1 Initial Proration. Within [The confidential material contained herein has been omitted and has been separately filed with the Commission.] days after the Closing Date, the parties shall prorate the following items as of the Closing Date:

(a) Taxes. All real estate taxes with respect to the Property shall be prorated between Liberty and the Company as of the Closing Date.

(b) Rents. Rent shall be prorated as of the Closing Date, except that no proration shall be made for rents delinquent as of the Closing Date (hereinafter called the “Delinquent Rents”). The Company shall have no liability to Liberty for the Delinquent Rents and shall have no obligation to collect same, provided, however, amounts collected by the Company or the Entities from tenants owing Delinquent Rents shall be applied first to rents owed by such tenant accruing from and after the Closing Date and then to Delinquent Rents. Any such amounts applicable to Delinquent Rents received by the Company or the Entities shall be forwarded to Liberty within fifteen (15) days of receipt thereof. Liberty reserves the right to pursue legal remedies against tenants owing Delinquent Rents so long as pursuit of its legal remedies does not cause the tenant to be evicted.

(c) Operating Costs. All operating expenses, including utilities (to the extent not paid directly by tenants), maintenance and other operating costs and expenses incurred by the Entities in connection with the ownership, operation, maintenance and management of the Property shall be prorated between Liberty and the Company as of the Closing.

(d) Insurance Premiums. Insurance premiums shall be prorated as of the Closing Date.

(e) Other Income and Expenses. All other income from, and expenses of, the Property, including but not limited to public utility charges, maintenance charges and service

charges, shall be prorated as of the Closing Date and the Company shall assume such expenses for periods subsequent to Closing.

(f) Federal, State and Local Taxes. To the maximum extent permissible, for Federal, State and local tax purposes the parties will cause the Entities and their subsidiaries to treat the Closing Date as the beginning of a fiscal period. Liberty will file all returns and pay all taxes owing for periods through the day preceding the Closing Date and the Company will file all returns and pay all taxes owing for periods beginning with the Closing Date. If and to the extent that such filing of separate returns is not permitted by any taxing authority, and as to any tax that applies to a period both before and after the Closing Date, the parties will cooperate in the furnishing of information necessary to the preparation and filing of returns, and will pay their respective shares of tax liability in proportion to their respective shares of the thing taxed (for example, gross receipts or net income). The obligations of the parties hereunder shall survive Closing until each such tax return has been filed, all such taxes owing have been paid and such returns and payments are no longer subject to contest by the taxing authority. Notwithstanding the foregoing, for tax purposes, closing shall be deemed to occur at 11:59 p.m. (local Washington, D.C. time) on the day preceding the Closing Date.

(g) Assumed Financing. Interest, credits, costs and expenses (other than the costs and expenses described in Section 6.4(b)(iii), which shall be the sole obligation of the Company) related to the Assumed Financing will be adjusted and apportioned between Liberty and the Company in accordance with the following: (i) prepaid interest will be paid to Liberty by the Company and accrued, but unpaid interest will be paid by Liberty with both to be apportioned as of the day preceding the Closing Date; and (ii) Liberty will be entitled to receive the amounts (including accrued interest) of any escrow and other sums on deposit with a lender under the Assumed Financing (including any escrow reserves) when disbursed by the holder of such Assumed Financing.

7.2 Adjustments; Reproration. After receipt of final financial statements for the Entities for the current year or applicable fiscal period, Liberty shall prepare and present to NYSCRF a calculation of the reproration of the profits and losses of the Entities to be passed through to the Company. The parties shall make the appropriate adjusting payment between them within 30 days after presentment to NYSCRF of Liberty’s calculation. This provision shall survive the Closing.

and Liabilities”), which may arise on account of or in any way be connected with the ownership of the Property first arising or accruing on or after to the Closing Date, excluding, however, any Liberty Losses and Liabilities (hereinafter defined). The Company also agrees to indemnify, defend and hold Liberty harmless from any claims, liabilities or costs (including reasonable attorneys’ fees) arising from the Company’s failure to perform said obligations, provided the same do not arise on account of Liberty Losses and Liabilities. As used herein, “Liberty Losses and Liabilities” are any Losses and Liabilities which may arise on account of or in any way be connected with any action by Liberty or the LLC (a) that was not taken in the reasonable belief that it was within their scope of authority under the Partnership Agreement, (b) constituting fraud, bad faith, negligence or willful misconduct, or a breach of the standards set forth in Section 6.02(d) of the Partnership Agreement, or (c) in violation of securities laws or criminal laws.

8. SURVIVAL

8.1 Survival. Except as otherwise expressly provided herein, all warranties representations, covenants, obligations and agreements contained in this Agreement shall survive the execution and delivery of this Agreement and shall survive the Closing for a period of one (1) year and any right of action for the breach of any representation, warranty or covenant contained herein shall not merge with the Assignment but shall survive the Closing for such one (1) year period and may be enforced by the Company. In addition to all other remedies that NYSCRF and/or the Company may have at law or in equity, the Company may offset any final, non-appealable judgment it obtains against Liberty against any distributions due to Liberty from the Company.

If Liberty elects to cure the default specified in NYSCRF’s Default Notice, Liberty shall commence to cure such default within fifteen (15) days from the date of such election and diligently pursue such cure to completion within forty-five (45) days (“Liberty’s Cure Period”).

(e) The terms “release,” “disposal,” “storage” and “treatment” shall have the meaning set forth in CERCLA, RCRA, the regulations promulgated thereunder and any other similar Hazardous Materials Laws.

13.2 Liberty’s Environmental Representations and Warranties. Liberty hereby represents and warrants to NYSCRF that except as set forth on Exhibit I or in those certain Phase I Environmental Site Assessments delivered to NYSCRF by Liberty and listed on Schedule 13.2 attached hereto (collectively, the “Environmental Reports”):

(a) Liberty has not received any written notice of any civil, criminal or administrative suit, claim, hearing, violation, investigation, proceeding or demand against the Property or against Liberty or the Company with respect to the Property relating in any way to a release or use of Hazardous Materials or compliance with Hazardous Materials Laws.

(b) Liberty has received no written notice that the Property violates Hazardous Materials Laws.

(d) Liberty has received no written notice asserting that there are Hazardous Materials on, in or under the Property in violation of any Hazardous Materials Laws.

(e) The Property has never been used by Liberty, or to Liberty’s best knowledge, by any third parties, to generate, treat, store, dispose of or transport Hazardous Materials in quantities that require remediation under, or are otherwise in violation of, any Hazardous Materials Laws.

13.3 Environmental Covenant. Liberty shall not knowingly conduct or authorize Hazardous Materials Contamination at the Property occurring after the date hereof and on or prior to the Closing Date, and shall promptly notify NYSCRF in writing of any existing or pending investigation or inquiry by any governmental authority in connection with any Hazardous Materials Laws relating to the Property of which Liberty has received written notice or has actual knowledge (as defined in Section 4.3).

13.4 Environmental Indemnification.

(a) Liberty hereby agrees to indemnify, defend and hold harmless NYSCRF and the Company from and against any Losses arising out of any material misrepresentation by Liberty in the representations and warranties set forth in Section 13.2 or by any willful breach of the covenants set forth in Section 13.3.

(b) Assumption of Defense.

(i) If a party entitled to indemnification hereunder (the “Indemnified Party”) notifies the party liable for such indemnification (the “Indemnifying Party”) of any claim, demand, action, administrative or legal proceeding, investigation or allegation adverse to the Indemnified Party and as to which the indemnity provided for in Section 13.4(a) applies (a “Potential Claim”), Indemnifying Party shall assume on behalf of Indemnified Party and conduct with due diligence and in good faith the investigation and defense thereof and the response thereto and shall be entitled, at Indemnifying Party’s sole discretion, to settle or otherwise dispose of any such Potential Claim; provided, that Indemnifying Party shall have the right to cure such matter that is the subject of the Potential Claim (subject to the rights of the owner of the Property at the time of such cure to approve the manner of such cure) if such cure will not result in additional liability or material loss of rights to Indemnified Party, and provided further that Indemnified Party have the right to be represented by advisory counsel of its own selection and at its own expense; and provided further, that if any such claim, demand, action, proceeding, investigation or allegation involves both Indemnifying Party and Indemnified Party and Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are inconsistent with or in addition to those available to Indemnifying Party, then Indemnified Party shall have the right to select separate counsel reasonably acceptable to Indemnifying Party to participate in the investigation and defense of and response to such claim, demand, action, proceeding, investigation or allegation on its own behalf at Indemnifying Party’s expense.

(ii) If any claim, demand, action, proceeding, investigation or allegation arises as to which the indemnity provided for in this Section 13.4 applies, and Indemnifying Party fails to assume as soon as reasonably practical the defense of Indemnified Party, then Indemnified Party may contest (or, with the prior written consent of Indemnifying Party, settle) the claim, demand, action, proceeding, investigation or allegation at Indemnifying Party’s expense using counsel selected by Indemnified Party and reasonably acceptable to Indemnifying Party.

(c) Notice of Losses. If Indemnified Party receives a written notice of Losses that Indemnified Party believes are covered by this Section 13.4, then Indemnified Party shall promptly furnish a copy of such notice to Indemnifying Party. The failure to so provide a copy of the notice to Indemnifying Party shall not excuse Indemnifying Party from its obligations under this Section 13.4; provided, that if Indemnifying Party is unaware of the matters described in the notice and such failure renders unavailable defenses that Indemnifying Party might otherwise assert, or precludes actions that Indemnifying Party might otherwise take to minimize its obligations hereunder, then Indemnifying Party shall be excused from its obligation to indemnify Indemnified Party against assessments, fines, costs and expenses, if any, which would not have been incurred but for such failure. For example, if Indemnified Party fails to provide Indemnifying Party with a copy of a notice of an obligation covered by the indemnity set out in Sections 13.4(a) and Indemnifying Party is not otherwise already aware of such obligation, and if as a result of such failure Indemnified Party becomes liable for penalties and interest covered by the indemnity in excess of the penalties and interest that would have accrued if Indemnifying Party had been promptly provided with a copy of the notice, then Indemnifying Party will be excused from any obligation to Indemnified Party to pay the excess and Indemnified Party shall indemnify Indemnifying Party with respect to any such excess.

(d) Rights Cumulative. The rights of NYSCRF and the Company under this Article 13 shall be in addition to any other rights and remedies of NYSCRF and the Company against Liberty pursuant to CERCLA and NYSCRF and the Company each expressly retain any right of reimbursement or contribution thereunder.

14. NO ASSUMPTION

14.1 No Assumption. The Company is not and is not deemed to be, a successor of Liberty, it being understood that Liberty is contributing to and the Company is acquiring only the Contributed Interests and the Purchase Money Loan Documents, subject to the Merger Loan, the Liberty Loan and the Assumed Financing, and the rights and obligations arising thereunder; and it is expressly understood and agreed that, except as may otherwise be expressly provided in this Agreement and in the documents delivered at the Closing, NYSCRF has not and does not hereby assume or agree to assume any liability whatsoever of Liberty.

15. NOTICES

15.1 Notices. Any notice, request, demand, instruction or other communication to be given to either party hereunder, except those required to be delivered at the Closing, shall be in writing, and shall be deemed to be delivered (a) upon receipt, if delivered by facsimile, (b) upon receipt or rejection if sent by hand delivery or (c) upon delivery to a nationally recognized overnight air courier service such as UPS or Federal Express, each addressed as follows:
