CONTRIBUTION AGREEMENT




     THIS CONTRIBUTION AGREEMENT (including all exhibits, hereinafter referred to as this
“Agreement”) is made and entered into as of ___, 2010 (the “Effective Date”)
by and among CoreSite, L.P., a Delaware limited partnership (the “Operating Partnership”),
CoreSite Realty Corporation Inc., a Maryland corporation (the “Company”), and the entities
listed on Exhibit A hereto (each referred to herein as a “Contributor,” and collectively as
the “Contributors.”)



RECITALS




     A. The Operating Partnership desires to consolidate the ownership of a portfolio of properties
set forth on Exhibit A hereto (the “Properties”) through a series of transactions (the
“Formation Transactions”) whereby the Operating Partnership will acquire the interests in
certain limited partnerships and limited liability companies set forth on Exhibit A (such limited
partnerships and limited liability companies, each a “Partnership” and collectively, the
“Partnerships”), which currently own, lease and/or manage, directly or indirectly, the
Properties.



     B. The Formation Transactions relate to the proposed initial public offering (the “Public
Offering”) of the common stock (“Common Stock”) of the Company, which will operate as a
self-administered and self-managed real estate investment trust (“REIT”) within the meaning
of Section 856 of the Internal Revenue Code of 1986, as amended (the “Code”) and which is
the sole general partner of the Operating Partnership.



     C. Each Contributor owns interests in the Partnerships set forth opposite such Contributor’s
name on Exhibit A, which Partnerships own or hold, directly or indirectly, fee or leasehold
interests in the properties set forth on Exhibit A. As used herein, “Partnership
Agreement” means the respective partnership agreement or limited liability company agreement,
as applicable, under which each Partnership was formed (including all amendments or restatements).







     D. Each Contributor desires to, and the Operating Partnership desires such Contributor to,
contribute to the Operating Partnership all of such Contributor’s right, title and interest, free
and clear of all Liens (as defined in Exhibit C), as a partner or member in each of the
Partnerships set forth opposite such Contributor’s name on Exhibit A, including, without
limitation, all of such Contributor’s voting rights and interests in the capital, profits and
losses of such Partnerships or any property distributable therefrom, constituting all of its
interests in and to such Partnerships (such right, title and interest in and to the Partnerships
are hereinafter collectively referred to as the “Partnership Interests”), in exchange for
common units in the Operating Partnership representing a fractional, undivided share of the limited
partnership interests therein (“OP Units”) having the rights, preferences and privileges
that are set forth in the Agreement of Limited Partnership of the Operating
Partnership attached as Appendix C hereto.







     NOW, THEREFORE, for and in consideration of the foregoing premises, and the mutual
undertakings set forth below, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:



1









 





TERMS OF AGREEMENT

ARTICLE 1.


CONTRIBUTION OF PARTNERSHIP INTERESTS

AND EXCHANGE FOR PARTNERSHIP UNITS








     Section 1.1 Contribution of Partnership Interests. At the Closing (as defined in Section 2.2
below) and subject to the terms and conditions contained in this Agreement, each Contributor shall
contribute, transfer, assign, convey and deliver to the Operating Partnership, free and clear of
all Liens (other than Liens that will be released upon consummation of the Public Offering and the
other related debt financing transactions contemplated thereby), all of such Contributor’s right,
title and interest to the Partnership Interests held by such Contributor. The contribution and
assumption of each Contributor’s Partnership Interests shall be evidenced by a Contribution and
Assumption Agreement in substantially the form of Exhibit B attached hereto (the “Contribution
and Assumption Agreement”). The parties shall take such additional actions and execute such
additional documentation as may be required by each relevant Partnership Agreement and the Agreement of Limited Partnership of the Operating Partnership, the contemplated form
of which is attached as Appendix C (the “OP Agreement”) in order to effect the transactions
contemplated hereby. Additionally, the Contributors, the Operating Partnership and the Company
agree that, from and after the Closing, the Contributors shall no longer be members or limited
partners or, if applicable, a managing member or general partner of any Partnership, and after the
Closing shall have no obligations or responsibilities as a member, limited partner, managing member
or general partner, as applicable, under any Partnership Agreement.







     Section 1.2 Existing Loans and Letters of Credit.



          (a) Certain Properties are encumbered with certain financings as described on Schedule 1.2
(each an “Existing Loan” and collectively the “Existing Loans”). Such notes, deeds
of trust and all other documents or instruments evidencing or securing such Existing Loans,
including any financing statements, guarantees, and any amendments, modifications and assignments
of the foregoing, shall be referred to, collectively, as the “Existing Loan Documents.”
Each Existing Loan shall be considered a “Permitted Encumbrance” for purposes of this
Agreement. With respect to each Existing Loan that is designated on Schedule 1.2 as an
“Assumed Loan”, each shall remain outstanding following the closing (subject to obtaining
prior to the Closing, any necessary consents from the holder of each mortgage or deed of trust
related to such Assumed Loan (in each case a “Lender” and collectively the
“Lenders”)) ; provided, however, that the Operating Partnership may nonetheless, in its
sole discretion, cause any Assumed Loan to be refinanced or repaid after the Closing. With respect
to each Existing Loan that is designated on Schedule 1.2 as a “Refinanced Loan”, the
Operating Partnership shall cause such Refinanced Loan to be refinanced or repaid in connection
with the Closing. In addition, at or before the Closing, the Contributors shall have caused each
Lender related to the Assumed Loans to have released the Contributors and each of their affiliates
(other than the Partnerships or their subsidiaries) from any liability in respect of obligations
first arising on or after the Closing Date pursuant to any recourse obligations, guarantees,
indemnification agreements, letters of credit posted as security or other similar obligations under
the respective Existing Loan Documents. From and after the Closing and until such time as each
Existing Loan has been refinanced or repaid in full, or each Lender has otherwise agreed in writing
to release the Contributors and each of their affiliates (other than the Partnerships or their
subsidiaries) from any further liability in respect of obligations pursuant to any recourse
obligations, guarantees, indemnification agreements, letters of credit posted as security or other
similar obligations under the Existing Loan Documents, the Operating Partnership shall indemnify
the Contributors, and each of their affiliates (other than the Partnerships or their subsidiaries)
in respect of any such further liabilities that have not been so released.







2









 








          (b) In connection with the assumption of each Assumed Loan at the Closing or refinancing
or payoff of each Refinanced Loan at or after the Closing, as applicable, the Operating Partnership
shall bear and be responsible for any assumption fee or prepayment premium assessed by the
applicable Lender and associated with such assumption, refinancing or payoff prior to maturity, as
applicable, and any other reasonable fee, charge, legal fees, cost or expense incurred by or on
behalf of any Contributor in connection therewith (collectively, “Existing Loan Fees”), and
shall indemnify and hold harmless each Contributor from and against any liability under the
Existing Loans arising from and after the Closing (including by reason of the failure to have
obtained any necessary consents from each applicable Lender prior to Closing) and any Existing Loan
Fees. Nothing contained in this Agreement shall preclude the Operating Partnership from reducing
or increasing the indebtedness secured by the Partnership Interests below or above the amount
outstanding on the Existing Loans in connection with any refinancing which may occur concurrently
with, or after, Closing. The Contributors acknowledge that they shall each be obligated to use
commercially reasonable efforts (at no cost or expense to the Contributors) along with the
Operating Partnership in seeking to obtain approval of the assumption of an Existing Loan or in
beginning the process for any refinancing or payoff of an Existing Loan (such as, without
limitation, requesting a payoff statement from the holder(s) of such Existing Loan), as applicable.




          (c) Attached as Schedule 1.2(c) is a list of certain letters of credit that were issued
under facilities established by an affiliate of one or more of the Contributors. Upon the closing
of the Public Offering and the related debt financing transactions, the Operating Partnership shall
take such actions as are necessary to replace such letters of credit with letters of credit issued
under a facility establish by the Operating Partnership. In the event that the beneficiary of any
of the letters of credit listed on Schedule 1.2(c) has not released such letter of credit as of the
date of the Public Offering (each, an “Unreleased LC”), the Operating Partnership shall
deliver to the Contributor whose affiliate established the facility under which such Unreleased LC
was distributed a “backstop” letter of credit in the same amount and having the same term as the
Unreleased LC (including any applicable “evergreen” provision), which backstop letter of credit may
be drawn upon in the event that the Unreleased LC is drawn upon for any reason after the Closing.
The Operating Partnership shall continue following the closing to use reasonable efforts to replace
the Unreleased LC and upon the release and return of such Unreleased LC, the applicable Contributor
shall return the related backstop LC.








     Section 1.3 Consideration and Exchange of Equity. The Operating Partnership shall, in exchange
for the Partnership Interests, transfer to the Contributors the total number of OP Units set forth
in Exhibit D (the “OP Unit
Consideration”).
The parties acknowledge that the transfer of OP Units to each Contributor shall be evidenced
by either an amendment to the OP Agreement (“Amendment”) or by certificates relating to
such OP Units

















3









 




(“OP Unit Certificates”), as determined by the Operating Partnership. The parties
shall take such additional actions and execute such additional documentation as may be required by
the relevant Partnership Agreements, the OP Agreement and/or the organizational documents of the
Company in order to effect the transactions contemplated hereby.




     Section 1.4 Purchase of OP Units by the Company.



          (a) Immediately following the IPO Closing (as defined in Section 2.2 below), the Company
shall purchase from each Contributor, and each Contributor shall sell and transfer to the Company,
free and clear of all liens, all of such Contributor’s right, title and interest to the number of
OP Units set forth in the appropriate column next to such Contributor’s name on Exhibit D for an
aggregate price equal to the product of (x) the number of OP Units sold by such Contributor to the
Company pursuant to this Section 1.4(a) multiplied by (y) the initial offering price per share of
Common Stock in the Public Offering (net of any underwriting discount).








          (b) In the event that the underwriters of the Public Offering exercise their overallotment
option at any time following or contemporaneous with the consummation of the Public Offering in
accordance with the terms specified in that certain
Underwriting Agreement, dated as of September
[___], 2010, executed by and between the
Company and the underwriters (the “Underwriting
Agreement”), immediately
following the consummation of the sale of the shares of Common Stock contemplated by such
overallotment option, the Company shall purchase from each Contributor, and each Contributor shall
sell and transfer to the Company, free and clear of all liens, all of such Contributor’s right,
title and interest to the number of OP Units set forth in the appropriate column next to such
Contributor’s name on Exhibit D for an aggregate price equal to the product of (x) the number of OP
Units sold by such Contributor to the Company pursuant to this Section 1.4(b) multiplied by (y) the
initial offering price per share of Common Stock in the Public Offering (net of any underwriting
discount).








     Section 1.5 Tax Treatment.



          (a) Any transfer, assignment and exchange by a Contributor effectuated pursuant to this
Agreement shall constitute a “Capital Contribution” by the applicable Contributor to the Operating
Partnership pursuant to Article [4] of the OP Agreement and is intended to be governed by Section
721(a) of the Code.




          (b) The Contributors and the Operating Partnership agree to the tax treatment described in
this Section 1.5, and the Operating Partnership and the Contributors shall file their respective
tax returns consistent with the above-described transaction structures.








     Section 1.6
Term of Agreement. If the Closing does not occur by September
30, 2010 (the
“Termination Date”), this Agreement shall be deemed terminated and shall be of no further
force and effect and no party hereto shall have any further obligations hereunder.

with the terms of this Agreement for the consideration described herein, will be duly and validly
issued, and free of any Liens other than any Liens arising through
one or more of the Contributors.
Upon such issuance, each Contributor will be admitted as a limited partner of the Operating
Partnership. At all times prior to the execution of this Agreement, the Operating Partnership had
no material assets, debts or liabilities of any kind.




          (e) Non-Contravention. Assuming the accuracy of the representations and
warranties of the Contributors made hereunder, none of the execution, delivery or performance of
this Agreement, any agreement contemplated hereby and the consummation of the contribution
transactions contemplated hereby and thereby will (A) result in a default (or an event that, with
notice or lapse of time or both would become a default) or give to any third party any right of
termination, cancellation, amendment or acceleration under, or result in any loss of any material
benefit, pursuant to any material agreement, document or instrument to which the Operating
Partnership or any of its properties or assets may be bound, or (B) violate or conflict with any
judgment, order, decree or law applicable to the Operating Partnership or any of its properties or
assets; provided in the case of (A) and (B), unless any such default, violation or conflict would
not have a Material Adverse Effect on the Operating Partnership.




          (f) No Litigation. There is no action, suit or proceeding pending or, to the
Operating Partnership’s knowledge, threatened against the Operating Partnership that, if adversely
determined, would have a Material Adverse Effect or would have a material adverse effect on the
Operating Partnership’s ability to consummate the transactions contemplated hereby.




          (g) No Prior Business. Since the date of its formation, the Operating Partnership
has not conducted any business, nor has it incurred any liabilities or obligations (direct or
indirect, present or contingent), in each case except in connection with the Formation Transactions
and the Public Offering and as contemplated under this Agreement.



          (h)
Tax Status. The Operating Partnership is and at the effective
time of the Public Offering will be, classified as a partnership and
not a publicly traded partnership taxable as a corporation, for
federal income tax purposes.



          (i) No Broker. Neither the Operating Partnership nor any of its officers,
directors or employees, to the extent applicable, has employed or made any agreement with any
broker, finder or similar agent or any person or firm which will result
in the obligation of any Contributor or any of their respective affiliates to pay any finder’s fee,
brokerage fees or commissions or similar payment in connection with transactions contemplated by
the Agreement (other than any underwriting discount payable to the
underwriters under the Underwriting Agreement).




     Section 3.2 Representations and Warranties with Respect to the Company. The Operating Partnership
and the Company hereby jointly and severally represent and warrant to each Contributor with respect
to the Company that:



          (a) Organization; Authority. The Company has been duly formed and is validly
existing under the laws of the jurisdiction of its formation, and has all requisite power and
authority to enter into this Agreement and to own, lease or operate its property and to carry on
its business as described in the Prospectus and, to the extent required under applicable law, is
qualified to do business






9









 







and is in good standing in each jurisdiction in which the nature of its business or the
character of its property make such qualification necessary except
where the failure to be so qualified and in good standing would not
have a Material Adverse Effect.




          (b) Due Authorization. The execution, delivery and performance of this Agreement
by the Company have been duly and validly authorized by all necessary action of the Company. This
Agreement and each agreement, document and instrument executed and delivered by or on behalf of the
Company pursuant to this Agreement constitutes, or when executed and delivered will constitute, the
legal, valid and binding obligation of the Company, each enforceable against the Company in
accordance with its terms, as such enforceability may be limited by bankruptcy or the application
of equitable principles.




          (c) Consents and Approvals. Assuming the accuracy of the representations and
warranties of the Contributors made hereunder and except in connection with the Public Offering, no
consent, waiver, approval or authorization of any third party or Governmental Entity is required to
be obtained by the Company in connection with the execution, delivery and performance of this
Agreement by the Operating Partnership or the Company and the transactions contemplated hereby,
except any of the foregoing that shall have been satisfied prior to the Closing Date or the IPO
Closing, as applicable, and except for those consents, waivers and approvals or authorizations, the
failure of which to obtain would not have a Material Adverse Effect.




          (d) Non-Contravention. Assuming the accuracy of the representations and
warranties of the Contributors made hereunder, none of the execution, delivery or performance of
this Agreement by the Operating Partnership or the Company, any agreement contemplated hereby and
the consummation of the contribution transactions contemplated hereby and thereby will (A) result
in a default (or an event that, with notice or lapse of time or both would become a default) or
give to any third party any right of termination, cancellation, amendment or acceleration under, or
result in any loss of any material benefit, pursuant to any material agreement, document or
instrument to which the Company or any of its properties or assets may be bound or (B) violate or
conflict with any judgment, order, decree, or law applicable to the Company or any of its
properties or assets; provided in the case of (A) and (B), unless any such default, violation or
conflict would not have a Material Adverse Effect.




          (e) Common Stock. Upon issuance thereof, the Common Stock issuable in exchange
for the OP Units upon the redemption of such OP Units in accordance with terms of the OP Agreement,
will be duly authorized, validly issued, fully paid and nonassessable, and not subject to
preemptive or similar rights created by statute or any agreement to which the Company is a party or
by which it is bound.




          (f) No Litigation. There is no action, suit or proceeding pending or, to the
Company’s knowledge, threatened against the Company that, if adversely determined, would have a
Material Adverse Effect or a material adverse effect on the ability of the Company to perform its
obligations under, this Agreement and the documents executed by it pursuant to this Agreement or to
consummate the transactions contemplated hereby or thereby.




          (g) No Prior Business. Since the date of its formation, the Company has not
conducted any business, nor has it incurred any liabilities or obligations (direct or indirect,
present or contingent), in each case except in connection with the Formation Transactions and the
Public Offering and as contemplated under this Agreement.




          (h) No Broker. Neither Company nor any of its officers, directors or employees, to
the extent applicable, has employed or made any agreement with any broker, finder or similar agent
or any person or firm which will result in the obligation of any
Contributor or any




10









 




of its respective affiliates to pay any finder’s fee, brokerage fees or commissions or similar
payment in connection with transactions contemplated by the Agreement
(other than any underwriting discount payable to the underwriters
under the Underwriting Agreement).




     Except as set forth in Section 3.1 and this Section 3.2, neither the Operating Partnership nor
the Company makes any representation or warranty of any kind, express or implied, and each
Contributor acknowledges that it has not relied upon any other such representation or warranty.







     Section 3.3 Representations and Warranties of the Contributors. Each Contributor severally, and
not jointly, represents and warrants to the Operating Partnership and the Company as provided in
Exhibit C attached hereto (subject to qualification by the disclosures in the disclosure schedule
attached hereto (the “Disclosure Schedule”)), and acknowledges and agrees to
be bound by the indemnification provisions contained therein.







     Section 3.4 Indemnification. From and after the Closing Date and in accordance with the
procedures described in Section 3.4 of Exhibit C hereto, mutatis mutandis, the Operating
Partnership and the Company jointly and severally shall indemnify, hold harmless and defend each
Contributor and its respective directors, officers, managers, members, partners and employees, as
well as its affiliates (each of which is an “Indemnified Contributor Party”) from and
against any and all claims, losses, damages, liabilities and expenses, including, without
limitation, amounts paid in settlement, reasonable attorneys’ fees, costs of investigation, costs
of investigative, judicial or administrative proceedings or appeals therefrom and costs of
attachment or similar bonds (collectively, “Losses”) arising out of or related to, or
asserted against, imposed upon or incurred by the Indemnified Contributor Party, to the extent
resulting from: (i) any breach of a representation, warranty or covenant of the Operating
Partnership or the Company contained in this Agreement or any Schedule, Exhibit, certificate or
affidavit, or any other document delivered pursuant hereto or thereto, and (ii) all fees, costs and
expenses of the Operating Partnership and the Company in connection with the transactions
contemplated by this Agreement.



ARTICLE 4.

COVENANTS




     Section 4.1 Covenants of the Contributors.



          (a) From the date hereof through the Closing, and except in connection with the Formation
Transactions, no Contributor shall, without the prior written consent of the Operating Partnership:




               (i) Sell, transfer (or agree to sell or transfer) or otherwise dispose of, or cause the sale,
transfer or disposition of (or agree to do any of the foregoing) all or any portion of its interest
in the Partnership Interests or all or any portion of its interest in the Properties; or



               (ii) Except as otherwise disclosed in the Disclosure Schedule, mortgage, pledge or encumber
all or any portion of its Partnership Interests or any of the Properties.



          (b) From the date hereof through the Closing, and except in connection with the Formation
Transactions, each Contributor shall, to the extent within its control, conduct each Partnership’s
business in the ordinary course of business consistent with past practice, and shall, to the extent
within its control and consistent with its obligations under each such Partnership’s operating
agreements, not permit any Partnership, without the prior written consent of the Operating
Partnership, to:




               (i) Enter into any material transaction not in the ordinary course of business with respect
to the Properties;



11









 





               (ii) Except as otherwise disclosed in the Disclosure Schedule, mortgage, pledge or encumber
(other than by Permitted Encumbrances) any assets of such Partnership, except (A) liens for taxes
not delinquent, (B) purchase money security interests in the ordinary course of such Partnership’s
business, and (C) mechanics’ liens being disputed by such Partnership in good faith and by
appropriate proceeding in the ordinary course of such Partnership’s business;



               (iii) Cause or permit any Partnership to change the existing use of any Property;



               (iv) Cause or take any action that would render any of the representations or warranties
regarding the Properties as set forth on Exhibit C untrue in any material respect;



               (v) File an entity classification election pursuant to Treasury Regulations Section
301.7701-3(c) on Internal Revenue Service Form 8832 (Entity Classification Election) to treat any
Partnership as an association taxable as a corporation for federal income tax purposes; or



               (vi) Make any distribution to its partners or members related to the Partnerships or the
Properties.



     Section 4.2 Tax Covenants.



          (a) The Contributors and the Operating Partnership shall provide each other with such
cooperation and information relating to any of the Partnership Interests or the Properties as the
parties reasonably may request in (i) filing any tax return, amended tax return or claim for tax
refund, (ii) determining any liability for taxes or a right to a tax refund, or (iii) conducting or
defending any proceeding in respect of taxes. Such reasonable cooperation shall include making
employees available on a mutually convenient basis to provide additional information and
explanation of any material provided hereunder. The Operating Partnership shall promptly notify
each Contributor upon receipt by the Operating Partnership or any of its affiliates of notice of
(x) any pending or threatened tax audits or assessments with respect to the income, properties or
operations of any of the Partnerships or with respect to any Property and (y) any pending or
threatened federal, state, local or foreign tax audits or assessments of the Operating Partnership
or any of its affiliates, in each case which may affect the liabilities for taxes of any of the
Contributors with respect to any tax period ending before or as a result of the Closing. Each
Contributor shall promptly notify the Operating Partnership in writing upon receipt by such
Contributor or any of its affiliates of notice of any pending or threatened federal, state, local
or foreign tax audits or assessments relating to the income, properties or operations of any of the
Partnerships or with respect to any Property. Each of the Operating Partnership and the
Contributors may participate at its own expense in the prosecution of any claim or audit with
respect to taxes attributable to any taxable period ending on or before the Closing Date,
provided, that the Contributors shall have the right to control the conduct of any such
audit or proceeding or portion thereof with respect to income taxes attributable to periods, or
portions thereof, ending on or prior to the Closing Date, and the Operating Partnership shall have
the right to control any other audits and proceedings.




          (b) The Operating Partnership shall prepare or cause to be prepared and file or cause to
be filed all tax returns of the Partnerships or their subsidiaries which are due after the Closing
Date. To the extent such returns relate to a period prior to or ending on the Closing Date, such
tax returns (including, for the avoidance of doubt, any amended tax returns) shall be prepared in a
manner consistent with past practice, except as otherwise required by applicable law. To the
extent such tax returns relate to income taxes attributable to a period prior to or ending on the
Closing Date, no later than thirty (30) days prior to the due date (including extensions) for
filing such returns, the Operating Partnership shall deliver






12









 







such income tax returns to the Contributors for their review and approval, which approval
shall not be unreasonably conditioned or withheld.




          (c) With respect to each Property that is contributed to the Operating Partnership
pursuant to this Agreement, the Operating Partnership and each Contributor agree that the Operating
Partnership shall use the “traditional method,” as described in Section 1.704-3(b) of the Treasury
Regulations promulgated under the Code, to make allocations of taxable income and loss among the
partners of the Operating Partnership.




ARTICLE 5.

WAIVERS AND CONSENTS




     Effective upon the Closing of the contribution and exchange of the Partnership Interests
pursuant to Articles 1 and 2 herein, each Contributor waives and relinquishes all rights and
benefits otherwise afforded to such Contributor under any Partnership Agreement, including, without
limitation, any rights of appraisal, rights of first offer or first refusal, buy/sell agreements,
and any right to consent to or approve of the sale or contribution by the other partners or members
of each Partnership of their Partnership Interests to the Operating Partnership, the Company or any
direct or indirect subsidiary thereof and any and all notice provisions related thereto.



ARTICLE 6.

MISCELLANEOUS




     Section 6.1 Further Assurances. The Contributors and the Operating Partnership shall take such
other actions and execute such additional documents following the Closing as the other may
reasonably request in order to effect the transactions contemplated hereby.



     Section 6.2 Counterparts. This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute one and the same
instrument.



     Section 6.3 Governing Law. This Agreement shall be governed by the internal laws of the State of
New York, without regard to the choice of laws provisions thereof.



     Section 6.4 Amendment; Waiver. Any amendment hereto shall be in writing and signed by all parties
hereto. No waiver of any provisions of this Agreement shall be valid unless in writing and signed
by the party against whom enforcement is sought.



     Section 6.5 Entire Agreement. This Agreement, the exhibits and schedules hereto constitute the
entire agreement and supersede conflicting provisions set forth in all other prior agreements and
understandings, both written and oral, among the parties with respect to the subject matter hereof
and thereof, as the case may be. Exhibit C is incorporated in this Agreement by reference in its
entirety, such that reference to this “Agreement” shall automatically include Exhibit C, and is
subject to all of the provisions of this Article 6.



     Section 6.6 Assignability. This Agreement shall be binding upon, and shall be enforceable by and
inure to the benefit of, the parties hereto and their respective heirs, legal representatives,
successors and assigns; provided, however, that this Agreement may not be assigned
(except by operation of law) by any party without the prior written consent of the other parties,
and any attempted assignment without such consent shall be void and of no effect.



13









 





     Section 6.7 Titles. The titles and captions of the Articles, Sections and paragraphs of this
Agreement are included for convenience of reference only and shall have no effect on the
construction or meaning of this Agreement.



     Section 6.8 Third Party Beneficiary. Except as may be expressly provided or incorporated by

third party beneficiary rights or any other rights of any kind in any customer, affiliate,
stockholder, partner, member, director, officer or employee of any party hereto or any other person
or entity.



     Section 6.9 Severability. If any provision of this Agreement, or the application thereof, is for
any reason held to any extent to be invalid or unenforceable, the remainder of this Agreement and
application of such provision to other persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto. The parties further agree to replace such
void or unenforceable provision of this Agreement with a valid and enforceable provision that will
achieve, to the extent possible, the economic, business and other purposes of the void or
unenforceable provision and to execute any amendment, consent or agreement deemed necessary or
desirable by the Operating Partnership to effect such replacement.



     Section 6.10 Notices. All notices, requests, claims, demands and other communications hereunder
shall be in writing and shall be given or made (and shall be deemed to have been duly given or made

of the transactions contemplated herein.

ARTICLE 2 — REPRESENTATIONS AND WARRANTIES

OF CONTRIBUTORS




     Except as set forth in the Disclosure Schedule or the Prospectus, each Contributor severally,
and not jointly, represents and warrants to the Operating Partnership and the Company as set forth
below in this Article 2 solely with respect to any Partnership Interest, Property or Entity,
directly or indirectly contributed to the Operating Partnership by such Contributor or to another
Contributor owned directly, or indirectly by the same real estate fund, which representations and
warranties are true and correct as of the date hereof and will (except to the extent expressly
relating to a specified date) be true and correct as of the Pre-Closing Date:







     2.1 Organization; Authority; Qualification. Each Entity contributed, directly or
indirectly, by such Contributor is duly formed, validly existing and in good standing (to the
extent applicable) under the laws of its jurisdiction of formation and each such Entity has the
requisite power and authority to carry on its business as it is presently conducted and, to the
extent required under applicable law, is qualified to do business in each jurisdiction in which the
nature of its business or the ownership, leasing or operation of its property make such
qualification necessary, except where failure to be so qualified would not have a Material Adverse
Effect. The Contributors have made available to the Operating Partnership true and correct copies
of the organizational documents of each such Partnership, with all amendments as in effect on the date
of this Agreement (collectively, the “Organizational Documents”). Schedule 2.1 of
the Disclosure Schedule lists each Partnership, its jurisdiction of formation and each partner, member
or other equity owner of such Entity as of the date hereof.







     2.2 Due Authorization. Such Contributor has the legal capacity to enter into this
Agreement. The Agreement and each agreement, document and instrument executed and delivered by or
on behalf of such Contributor pursuant to the Agreement constitutes, or when executed and delivered
will constitute, the legal, valid and binding obligation of such Contributor, each enforceable
against such Contributor in accordance with its terms, as such enforceability may be limited by
bankruptcy or the application of equitable principles.



Exhibit C-3 









 





     2.3 Consents and Approvals. Except as shall have been satisfied prior to the Closing
Date and as set forth in Schedule 2.3 to the Disclosure Schedule, as of the date hereof, no
consent, waiver, approval or authorization of any third party or Governmental Entity is required to
be obtained by such Contributor or any Entity owned by such Contributor in connection with the
execution, delivery and performance of the Agreement and the transactions contemplated hereby,
except for those consents, waivers, approvals or authorizations, the failure of which to obtain
would not have a Material Adverse Effect.



     2.4 Ownership of the Partnership Interests and other Entities.



          (a) Except for the Partnership Interests being contributed to the Operating Partnership
pursuant to this Agreement, no Partnership has issued any equity securities or other equity
interests therein (including, without limitation, any securities convertible into or exchangeable
or redeemable for any such equity securities or other equity interests) and there are no
outstanding subscriptions, calls, warrants, options or commitments of any kind for the granting or
issuance of any equity securities or other equity interests in any Partnership. Except as set
forth in Schedule 2.4(a) to the Disclosure Schedule, each Contributor is the sole owner of
the Partnership Interests being contributed by it, beneficially and of record, free and clear of
any Liens of any nature and has full power and authority to convey the Partnership Interests, free
and clear of any Liens, and, upon delivery of consideration for such Partnership Interests as
herein provided, the Operating Partnership will acquire good title thereto, free and clear of any
Liens other than any liens arising through the Operating Partnership. Except as set forth in
Schedule 2.4(a) to the Disclosure Schedule, no Contributor has granted to any other Person
any right to purchase, and there are no other agreements with respect to the voting or transfer of,
any Partnership Interest held by such Contributor.




          (b) Schedule 2.4(b) sets forth the name and jurisdiction of organization if each
Entity that is not a Partnership and the Partnership which, directly or indirectly, owns 100% of
the equity interests therein. Except for the equity interests owned by the Partnership or another
Entity that is 100% owned, directly or indirectly by such Partnership, no Entity has issued any
equity securities or other equity interests therein (including, without limitation, any securities
convertible into or exchangeable or redeemable for any equity securities) and there are no
outstanding subscriptions, calls, warrants, options or commitments of any kind for the granting or
issuance of any equity securities or other equity interests in such Entity. Except as set forth in
Schedule 2.4(b) to the Disclosure Schedule, each of the Partnerships or other Entities
designated as owning any of the equity interests on Schedule 2.4(b) is the sole owner of
such equity interests, beneficially and of record, free and clear of any Liens (other than
Permitted Liens). Except as set forth in Schedule 2.4(b) to the Disclosure Schedule, no
Entity has granted to any other Person any right to purchase, and there are no other agreements
with respect to the voting or transfer of, any equity securities issued by such Entity.




     2.5 No Violation. Except as shall have been cured to the satisfaction of the
Operating Partnership, consented to or waived in writing by the Operating Partnership prior to the
Closing Date or as set forth in Schedule 2.5 to the Disclosure Schedule, none of the
execution, delivery or performance of the Agreement, any agreement contemplated thereby and the
transactions contemplated hereby and thereby does or will, with or without the giving of notice,
lapse of time, or both, violate, conflict with, result in a breach of, or constitute a default
under or give to others any right of termination, acceleration, cancellation or other right adverse
to the Operating Partnership of (A) the organizational documents, including the operating
agreement, if any, of any Contributor or any of the Entities in which any Contributor holds an
interest to be contributed hereunder, (B) any agreement, document or instrument to which any
Contributor is a party or by which any Contributor or any Entity in which any Contributor holds an
interest to be contributed hereunder, are bound, or (C) any term or provision of any judgment,
order, writ, injunction, or decree, or require any approval, consent or waiver of, or make any
filing with,



Exhibit C-4 









 




any person or Governmental Entity or foreign, federal, state, local or other law binding on
any Contributor or the Entities in which either Contributor holds an interest to be contributed
hereunder, or by which any Contributor, Entity or any of their assets or properties are bound or
subject; provided in the case of (B) and (C) above, unless any such violation, conflict, breach,
default or right would not have a Material Adverse Effect or on the
ability of any Contributor to consummate the transactions
contemplated hereby.




     2.6 Non-Foreign Status. Each Contributor is a United States person (as defined in
Section 7701(a)(30) of the Code), and is, therefore, not subject to the provisions of the Code
relating to the withholding of sales proceeds to foreign persons, and is not subject to any state
withholding requirements. Each Contributor will provide affidavits at the Closing to this effect
as provided for in Section 2.3(d) of the Agreement.



     2.7 Investment Purposes. Each Contributor acknowledges its understanding that the
offering and issuance of OP Units to be acquired pursuant to the Agreement are intended to be
exempt from registration under the Securities Act of 1933, as amended and the rules and regulations
in effect thereunder (the “Act”) and that the Operating Partnership’s reliance on such
exemption is predicated in part on the accuracy and completeness of the representations and
warranties of the Contributors contained herein. In furtherance thereof, each Contributor
represents and warrants to the Company and the Operating Partnership as follows:



          2.7.1
Investment. Such Contributor is acquiring OP Units (and any
Common Stock which may be received upon redemption of such OP Units) solely for its own account
for the purpose of investment and as a nominee or agent for any other person and not with a view
to, or for offer or sale in connection with, any distribution of any thereof. Such Contributor
agrees and acknowledges that it will not, directly or indirectly, offer, transfer, sell, assign,
pledge, hypothecate or otherwise dispose of (hereinafter, “Transfer”) any of the OP Units
(and any Common Stock which may be received upon redemption of such
OP Units), unless (i) the Transfer is pursuant to an effective registration statement under the Act and
qualification or other compliance under applicable blue sky or state securities laws, (ii) counsel
for such Contributor (which counsel shall be reasonably acceptable to the Operating Partnership)
shall have furnished the Operating Partnership with an opinion, reasonably satisfactory in form and
substance to the Operating Partnership, to the effect that no such registration is required because
of the availability of an exemption from registration under the Act, or (iii) the Transfer is
otherwise permitted by the OP Agreement. The term “Transfer” shall not include any redemption or
exchange of the OP Units for REIT Shares pursuant to Section 15.1 of the OP Agreement.
Notwithstanding the foregoing, no Transfer shall be made unless it is permitted under the OP
Agreement.








          2.7.2 Knowledge. Such Contributor is knowledgeable, sophisticated and experienced in
business and financial matters and fully understands the limitations on transfer imposed by the
Federal securities laws and as described in the Agreement and the OP
Agreement. Such Contributor is able to bear the
economic risk of holding the OP Units for an indefinite period and is able to afford the complete
loss of its investment in the OP Units; such Contributor has received and reviewed all information
and documents about or pertaining to the Company, the Operating Partnership, the business and
prospects of the Company and the Operating Partnership and the issuance of the OP Units, as such
Contributor deems necessary or desirable, has had cash flow and operations data for the Properties
made available by the Operating Partnership upon request and has been given the opportunity to
obtain any additional information or documents and to ask questions and receive answers about such
information and documents, the Company, the Operating Partnership, the Properties, the business and
prospects of the Company and the Operating Partnership and the OP Units, which such Contributor
deems necessary or desirable to evaluate the merits and risks related to its investment in the OP
Units, and to conduct its own independent valuation of the Properties. Such Contributor has
reviewed with its legal counsel and tax advisors the forms of the Articles of Amendment and
Restatement, the form of which is attached hereto as
Appendix A, the Amended and Restated Bylaws of
the Company, the form of which is attached hereto as
Appendix B (the “Amended and Restated
Bylaws”), and the OP Agreement.








Exhibit C-5 









 





          2.7.3 Holding Period. Such Contributor acknowledges that it has been advised that (i)
the OP Units are not redeemable or exchangeable for cash or, at the option of the REIT, REIT Shares
for a minimum of twelve (12) months, (ii) the OP Units issued pursuant to the Agreement, and any
REIT Shares issued in exchange for, or in respect of a redemption of, the OP Units, are “restricted
securities” (unless registered in accordance with applicable U.S. securities laws) under applicable
federal securities laws and may be disposed of only pursuant to an effective registration statement
or an exemption therefrom and such Contributor understands that the Operating Partnership has no
obligation or intention to register any OP Units, except to the extent set forth in the
Registration Rights Agreement; accordingly, such Contributor may have to bear indefinitely, the
economic risks of an investment in such OP Units, (iii) a restrictive legend in the form hereafter
set forth shall be placed on the OP Unit Certificates (and any certificates representing REIT
Shares for which OP Units may, in certain circumstances, be exchanged or redeemed), and (iv) a
notation shall be made in the appropriate records of the Operating Partnership indicating that the
OP Units (and any REIT Shares for which OP Units may, in certain circumstances, be exchanged or
redeemed) and are subject to restrictions on transfer.




          2.7.4 Accredited Investor. Such Contributor is an “accredited investor” (as such term
is defined in Rule 501 (a) of Regulation D under the Act).




          2.7.5 Legend. Each OP Unit Certificate, if any, issued pursuant to the Agreement (and
any certificates representing REIT Shares for which OP Units may, in certain circumstances, be
exchanged or redeemed), unless registered in accordance with applicable U.S. securities laws, shall
bear the following legend:





The securities evidenced hereby have not been registered under the Securities Act of 1933,
as amended (the “Act”), or the securities laws of any state and may not be sold,
transferred or otherwise disposed of in the absence of such registration, unless, except in
limited circumstances, the transferor delivers to the company an opinion of counsel
satisfactory to the company, to the effect that the proposed sale, transfer or other
disposition may be effected without registration under the Act and under applicable state
securities or “Blue Sky” laws;



     In addition to the foregoing legend, each certificate (if any) representing any REIT Shares
for which OP Units may, in certain circumstances, be exchanged or redeemed shall also bear a legend
which generally provides the following:




The shares represented by this certificate are subject to restrictions on Beneficial and
Constructive Ownership and Transfer for the purpose, among others, of the Corporation’s
maintenance of its status as a Real Estate Investment Trust under the Internal Revenue Code
of 1986, as amended (the “Code”). Subject to certain further restrictions and except as
expressly provided in the Corporation’s Charter, (i) no Person may Beneficially or
Constructively Own shares of the Corporation’s Capital Stock in excess of 9.8% (in value or
number of shares) of the outstanding shares of Capital Stock of the Corporation; (ii) no
Person may Beneficially or Constructively Own shares of Capital Stock of the Corporation in
excess of 9.8% of the value of the total outstanding shares of Capital Stock of the
Corporation; (iii) no Person may Beneficially or Constructively Own Capital Stock that would
result in the Corporation being “closely held” under Sections 856(h)(1)(B) and 856(h)(3) of
the Code or otherwise cause the Corporation to fail to qualify as a REIT; and (iv) no Person
may Transfer shares of Capital Stock if such Transfer would result in the Capital Stock of
the Corporation being owned by fewer than 100 Persons. Any Person who Beneficially or
Constructively Owns or attempts to Beneficially or Constructively Own shares of Capital
Stock which causes or will cause a Person to Beneficially or Constructively Own shares of
Capital Stock in excess or in violation of the above limitations must immediately notify the
Corporation. If any of the restrictions on transfer or ownership are



Exhibit C-6 









 






violated, the shares of Capital Stock represented hereby, together with any dividends or
distributions thereon will be automatically transferred to a Trustee of a Trust for the
benefit of one or more Charitable Beneficiaries. In addition, the
Corporation may redeem shares upon the terms and conditions specified by the Board of Directors in its sole
discretion if the Board of Directors determines that ownership or a Transfer or other event
may violate the restrictions described above. Furthermore, upon the occurrence of certain
events, attempted Transfers in violation of the restrictions described above may be void
ab initio. All capitalized terms in this legend have the meanings defined
in the Charter of the Corporation, as the same may be amended from time to time, a copy of
which, including the restrictions on transfer and ownership, will be furnished to each
holder of Capital Stock of the Corporation on request and without charge. Requests for such
a copy may be directed to the Secretary of the Corporation at its Principal Office.



     2.8 No Brokers. Except as set forth in Schedule 2.8 to the Disclosure
Schedule, no Contributor nor any of their or their respective officers, directors or employees, to
the extent applicable, has employed or made any agreement with any broker, finder or similar agent
or any person or firm which will result in the obligation of the Company, the Operating Partnership
or any of their affiliates (including any of the Partnerships and/or Entities) to pay any finder’s
fee, brokerage fees or commissions or similar payment in connection with the transactions
contemplated by the Agreement.



     2.9 Taxes.



          (a) To each Contributor’s Knowledge, no Tax lien exists with respect to any Property
contributed by such Contributor, except for Permitted Encumbrances. Copies of the real property
Tax bills for such Property for the current Tax year have been furnished or made available to the
Operating Partnership, and such Tax bills are true and correct copies of all of the real property
Tax bills for such Tax year actually received with respect to each such Property by such
Contributor or the Entities or their agents. Each Acquired Entity has timely and properly filed
all Tax Returns required to be filed by it. All such Tax Returns are complete and accurate in all
material respects. All material Taxes shown on any Tax Return of an Acquired Entity or with
respect to each property have been paid or will be paid prior to the Closing Date or are being
contested in good faith. No Acquired Entity has waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency. No
deficiencies for any material amount of Taxes of any Acquired Entity or with respect to any
Property have been claimed, proposed or assessed, in each case, in writing, by any Tax authority
or other Governmental Entity. There are no audits, investigations, disputes, notices of deficiency
or claims for any material amount of Taxes of any Acquired Entity or with respect to any Property
pending or, to the Knowledge of either Contributor, threatened in writing in the last twelve
months. The representations made in this Section 2.9(a) refer only to past activities and are not
intended to serve as representations to, or a guarantee of, nor can they be relied on with respect
to, Taxes attributable to any period (or portion thereof) beginning after, or Tax positions, taken
after the Closing Date. Without limiting the foregoing, no Contributor makes any representation
with respect to, nor shall any Contributor have any liability for any Taxes payable as a result of
any reassessment completed following the Closing Date (whether as a result of the transactions
contemplated hereby or otherwise) whether or not such reassessment applies retroactively to any
period, or any portion of any period, prior to the Closing Date.




          (b) For federal income Tax purposes, each Entity being acquired by the Operating Partnership
from such Contributor (each such entity, an “Acquired Entity”) is, and at all times during
its existence has been a partnership or limited liability company taxable either (i) as a
partnership (rather than an association or a publicly traded partnership taxable as a corporation)
or (ii) a disregarded entity.







Exhibit C-7 









 








     2.10 Litigation. Except as set forth in Schedule 2.10 to the Disclosure
Schedule, there is no Action, litigation, claim or other proceeding, either judicial or
administrative (including, without limitation, any governmental action or proceeding), pending or,
to each Contributor’s Knowledge, threatened in writing in the last twelve months, against any
Property, any Partnership Interests, any Contributor, or any of the Entities or that would
reasonably be expected to adversely affect the Contributors’ ability to consummate the transactions
contemplated hereby. No Contributor is bound by any outstanding order, writ, injunction or decree
of any court, Governmental Entity or arbitration against or affecting all or any portion of its
Partnership Interests, Partnership Interests, the Contributed Assets, or any Entity which in any
such case would impair either Contributor’s ability to enter into and perform all of its
obligations under the Agreement or would have a Material Adverse Effect.



     2.11 Compliance With Laws. In connection with the operation of the Properties, except
as set forth in Schedule 2.11 to the Disclosure Schedule, to each Contributor’s Knowledge,
the Properties contributed by such Contributor have been maintained and the Contributors have not
received written notice that any such Property is not in compliance in all material respects with
all applicable laws, ordinances, rules, regulations, codes, orders and statutes (including, without
limitation, those currently relating to fire safety, conservation, parking, Americans with
Disabilities Act, zoning and building laws) whether federal, state or local, except where the
failure to so comply would not have a Material Adverse Effect. Compliance with Environmental Laws
is not addressed by this Section 2.11, but rather solely by Section 2.15.



     2.12 Real Property.



          (a) Except
as described in Schedule 2.12(a) to the Disclosure Schedule, the Partnership or
other Entity that owns each of the Properties that is designated as owned real property in the
Prospectus has good and marketable title in fee simple to such Property free and clear of all
Liens, except Permitted Encumbrances.




          (b) Except
as described in Schedule 2.12(b) to the Disclosure Schedule, the Partnership or
other Entity that leases each of the Properties that is designated as leased real property in the
Prospectus has a valid leasehold interest in, and enjoys peaceful and undisturbed possession
(consistent with historical use) of such real property, in each case free and clear of all Liens,
except Permitted Encumbrances. No Entity has received any written notice of any material uncured
default under any of the real property leases pursuant to which it leases such properties, and to
the Contributors’ knowledge there is no material uncured default by any landlord thereunder, except
in each case as would not reasonably be expected to have a Material Adverse Effect.




     2.13 Eminent Domain. There is no existing or, to each Contributor’s Knowledge,
proposed or threatened condemnation, eminent domain or similar proceeding, or private purchase in
lieu of such a proceeding, in respect of all or any material portion of the Properties contributed
by such Contributor.



     2.14 Licenses and Permits. Except as set forth in Schedule 2.14 to the
Disclosure Schedule, to each Contributor’s Knowledge, all licenses, permits or other governmental
approvals (including certificates of occupancy) required to be obtained by the owner of any
Property contributed by such Contributor in connection with the construction, use, occupancy,
management, leasing and operation of such Properties have been obtained and are in full force and
effect and in good standing, except for those licenses, permits and other governmental approvals,
the failure of which to obtain or maintain in good standing would not have a Material Adverse
Effect.



     2.15 Environmental Compliance. To each Contributor’s Knowledge, except as may be
disclosed in Schedule 2.15 to the Disclosure Schedule or the environmental reports listed
therein (the



Exhibit C-8 









 




“Environmental Reports”) (true and correct copies of which have been made available to
the Operating Partnership), the Properties contributed by such Contributor are currently in
compliance with all Environmental Laws and Environmental Permits, except where the failure to so
comply would not have a Material Adverse Effect. No Contributor has received any written notice
from the United States Environmental Protection Agency or any other federal, state, county or
municipal entity or agency that regulates Hazardous Materials or public health risks or other
environmental matters or any other private party or Person claiming any current violation of, or
requiring current compliance with, any Environmental Laws or Environmental Permits or demanding

Governmental Entity or any third party. To such Contributor’s Knowledge, except as may be
disclosed in Schedule 2.15 to the Disclosure Schedule or the Environmental Reports, there
are no environmental conditions existing at, on, under, upon or affecting the Properties or any
portion thereof that would reasonably be likely to result in any claim, liability or obligation
under any Environmental Laws or Environmental Permit or any claim by any third party that would
have a Material Adverse Effect.

subleases, tenancies, possession agreements and occupancy agreements with tenants, subtenants or
licensees of such Property that individually constitute more than
2.0% of the aggregate rental revenues
of the Operating Partnership on a pro forma basis after giving effect to the transactions
contemplated hereby (the “Material Leases”) are identified on Schedule 2.16 to the
Disclosure Schedule. To each Contributor’s Knowledge, such Leases are in full force and effect,
except as indicated otherwise in Schedule 2.16 to the Disclosure Schedule or the rent roll
in the possession of the Operating Partnership on the date hereof. To each Contributor’s
Knowledge, except as set forth in Schedule 2.16 to the Disclosure Schedule or the rent roll
in the possession of the Operating Partnership on the date hereof, no monetary or material
non-monetary default (beyond applicable notice and cure periods) by any party exists under any such
Material Lease. To each Contributor’s Knowledge, no tenants under any of such Material Leases is
presently the subject of any voluntary or involuntary bankruptcy or insolvency proceedings.







     2.17 Tangible Personal Property. Except as set forth in Schedule 2.17 to the
Disclosure Schedule or as would not have a Material Adverse Effect, to each Contributor’s
Knowledge, each Entity’s interests in any fixtures or personal property that are reflected on the
financial statements of such Entity as owned by such Entity, are owned free and clear of all Liens
other than Permitted Encumbrances.



     2.18 Existing Loans. Schedule 2.18 to the Disclosure Schedule lists all
secured loans presently encumbering the Properties or any direct or indirect interest in any Entity
held by the Contributors, and any unsecured loans relating thereto to be assumed by the Operating
Partnership or any subsidiary of the Operating Partnership at Closing, as of the date hereof (the
“Disclosed Loans”), the approximate outstanding aggregate principal balance of which is
$___as of the date hereof. To each Contributor’s Knowledge, the Disclosed Loans and the
documents entered into in connection therewith (collectively, the “Disclosed Loan
Documents”) are in full force and effect and binding on the
Partnership or other Entity party thereto, and to the knowledge of
the Contributors, each other party thereto. No monetary or material non-monetary default (beyond applicable notice and cure periods)
by any Contributor, Partnership or other Entity exists under any of such Disclosed Loan Documents. True and correct copies of the
existing Disclosed Loan Documents have been made available to the Operating Partnership.



     2.19 Zoning. Except as set forth on Schedule 2.19 to the Disclosure Schedule,
the Contributors have not received (i) any written notice (which remains uncured) from any

similar rules or ordinances in any material respect, or (ii) any written notice of any pending or
threatened proceedings for the rezoning (i.e., as opposed to the current zoning) of any of the
Properties or any portion thereof except, in each case as would not have a Material Adverse Effect.




     2.20 Exclusive Representations. Except as set forth above in this Exhibit C, the
Contributors make no representation or warranty of any kind, express or implied, in connection with
all or any of the Property, the Partnership Interests, or any Entity, and each of the Operating
Partnership and the Company acknowledges that it has not relied upon any other such representation
or warranty. Except as set forth in Section 3.2(e) of the Agreement, each Contributor acknowledges

respect to the legal and tax consequences of the transfer to the Operating Partnership of such
Contributor’s Property, Partnership Interests, Partnership Interests, Contributed Assets, Assumed
Agreements, or Assumed Liabilities, nor with respect to either Contributor’s receipt of OP Units as
consideration therefor. Each Contributor acknowledges that it has not relied upon any other such
representation or warranty.



ARTICLE 3 — INDEMNIFICATION




     3.1 Survival Of Representations And Warranties; Remedy For Breach.



          (a) Subject to Section 3.6 of this Exhibit C, all representations and warranties contained in
this Exhibit C (as qualified by the Disclosure Schedule) or in any Schedule, Exhibit, certificate
or affidavit delivered pursuant to the Agreement shall survive the Closing.




          (b) Notwithstanding anything to the contrary in the Agreement or this Exhibit C, following the
Closing and issuance of OP Units to the Contributors, no Contributor shall be liable under this
Exhibit C or the Agreement for monetary damages (or otherwise) for breach of any of its
representations, warranties, covenants and obligations contained in this Exhibit C or the Agreement
(other than the covenants and obligations set forth in Section 2.5 thereof) or in any Schedule,
Exhibit, certificate or affidavit delivered by it pursuant thereto, other than pursuant to the
succeeding provisions of this Article 3, which, except as provided in Section 6.11 of the
Agreement, shall be the sole and exclusive remedy with respect thereto. In furtherance of the
foregoing provision relating to exclusive remedy, each of the Operating Partnership and the Company
hereby expressly waives any rights or claims it may have to pursue any remedy against the
Contributors or any of their affiliates following the Closing and issuance of OP Units to the
Contributors, whether under statute or common law, including, without limitation, any rights
arising under any Environmental Law, other than (i) as provided in this Article 3 or in
Section 6.11 of the Agreement, and (ii) with respect to the covenants and obligations described in
Section 2.5 of the Agreement. Except to the extent that any
Contributor distributes any of the OP Units pledged in accordance
with Section 3.3 below during the applicable survival period, in no event shall the constituent members, partners, employees,
officers, directors, managers, advisers, agents or representatives of any Contributor, or of any
Entity, be liable for monetary damages (or otherwise) for any breach of any of the representations,
warranties, covenants and obligations contained in this Exhibit C or the Agreement or in any
Schedule, Exhibit, certificate or affidavit delivered by the Contributors or any Entity pursuant
thereto.




     3.2 General Indemnification.



          (a) From and after the Closing Date, each Contributor shall severally, and not jointly (as
determined below), indemnify, hold harmless and defend the Operating Partnership and the Company
(each of which is an “Indemnified Party”) from and against any and all Losses asserted
against, imposed upon or incurred by the Indemnified Party, to the extent resulting from any breach
of a representation, warranty or covenant of the Contributors contained in the Agreement (as
qualified by all items set forth in the Prospectus and the Disclosure Schedule and including,
without limitation, this Exhibit C), or in any




Exhibit C-10 









 







Schedule, Exhibit, certificate or affidavit delivered by the Contributors pursuant thereto.
In each case, the Contributors shall only bear the fees, costs or expenses in connection with the
employment of one counsel (regardless of the number of Indemnified Parties).




          (b) With respect to any claim of an Indemnified Party pursuant to this Section 3.2, to the
extent available, the Operating Partnership agrees to use diligent good faith efforts to pursue and
collect any and all available proceeds and benefits of any right to defense under any insurance
policy which covers the matter which is the subject of the indemnification prior to seeking
indemnification from any Contributor until all proceeds and benefits, if any, to which the
Operating Partnership or the Indemnified Party is entitled pursuant to such insurance policy have
been exhausted; provided, however, that the Operating Partnership may make a claim under this
Section 3.2 even if an insurance coverage dispute is pending, in which case, if the Indemnified
Party later receives insurance proceeds with respect to any Losses paid by any Contributor for the
benefit of any Indemnified Party, then the Indemnified Party shall reimburse such Contributor in an
amount equivalent to such proceeds in excess of any deductible amount pursuant to Section 3.5(a) of
this Exhibit C up to the amount actually paid (or deemed paid) by such Contributor to the
Indemnified Party in connection with such indemnification (it being understood that all costs and
expenses incurred by the Contributors with respect to insurance coverage disputes shall constitute
Losses paid by the Contributors for purposes of Section 3.2(a) of this Exhibit C).




     3.3 Pledge Agreement. At the IPO Closing, each Contributor shall execute a Pledge
Agreement (in the form of Exhibit G to the Agreement) pursuant to which such Contributor’s
indemnity contained in this Article 3 shall be secured by a pledge of such Contributor’s OP Units
equal to 10% of such Contributor’s OP Unit Consideration, and which pledge will be in full
satisfaction of any indemnification obligations of such Contributor contained in this Article 3.



     3.4 Notice and Defense of Claims. As soon as reasonably practicable after receipt by
the Indemnified Party of notice of any liability or claim incurred by or asserted against the
Indemnified Party that is subject to indemnification under this Article 3, the Indemnified Party
shall give notice thereof to the Contributors, including liabilities or claims to be applied
against the indemnification deductible established pursuant to Section 3.5 hereof; provided that
failure to give notice to the Contributors will not relieve any Contributor from any liability
which it may have to any Indemnified Party, unless, and only to the extent that, such failure (a)
shall have caused prejudice to the defense of such claim or (b) shall have materially increased the
costs or potential liability of the Contributors by reason of the inability or failure of any
Contributor (due to such lack of prompt notice) to be involved in any investigations or
negotiations regarding any such claim. Such notice shall describe in reasonable detail the facts
known to such Indemnified Party giving rise to such claim, and the amount or good faith estimate of
the amount of Losses arising therefrom. Unless prohibited by law, such Indemnified Party shall
deliver to such Contributor, promptly after such Indemnified Party’s receipt thereof, copies of all
notices and documents received by such Indemnified Party relating to such claim. The Indemnified
Party shall permit the Contributors, at their own option and expense, to assume the defense of any
such claim by counsel selected by the Contributors and reasonably satisfactory to the Indemnified
Party, and to settle or otherwise dispose of the same; provided, however, that the Indemnified
Party may at all times participate in such defense at its sole expense; and provided
further, however, that no Contributor shall, in defense of any such claim, except with
the prior written consent of the Indemnified Party in its sole and absolute discretion, consent to
the entry of any judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff in question to all Indemnified Parties a
release of all liabilities in respect of such claims, or that does not result only in the payment
of money damages which are paid (or deemed paid) in full by the Contributors. If the Contributors
have not undertaken such defense within 30 days after such notice, or within such shorter time as
may be reasonable under the circumstances to the extent required by applicable law, then the
Indemnified Party shall have the right to undertake the defense, compromise or settlement of such
liability or claim on



Exhibit C-11 









 




behalf of and for the account of the Contributors and at their sole cost and expense (subject
to the limitations in Section 3.5); provided, however, that no Contributor will be obligated to
indemnify the Indemnified Parties for any compromise or settlement entered into without each
Contributor’s prior written consent, which consent shall not be unreasonably withheld or delayed.




     3.5 Limitations on Indemnification Under Section 3.2(a).



          (a) No Contributor shall be liable under Section 3.2(a) hereof unless and until the total
amount recoverable by the Indemnified Parties from the Contributors under Section 3.2(a) exceeds
one percent (1%) of the value of the aggregate OP Unit Consideration (valuing such OP Units based
upon the initial public offering price of the Common Stock) and then only to the extent of such
excess.




          (b) Notwithstanding anything contained herein to the contrary, (i) the maximum aggregate
liability of the Contributors under Section 3.2(a) hereof shall not exceed ten percent (10%) of the
value of the Contributors’ aggregate OP Unit Consideration
(valuing such OP Units based upon the initial public offering price
of the Common Stock), and (ii) to the extent any such
liability is directly related to or arises from a specific Property, such maximum aggregate
liability shall not exceed ten percent (10%) of the value of the Contributor’s aggregate OP Unit
Consideration in respect of the applicable Property (valuing such OP Units based upon the initial
public offering price of the Common Stock).




          (c) It is the intention of the parties hereto, that each Contributor shall only be liable for
breaches of representations made by such Contributor and by any other Contributor that is directly
or indirectly owned by the same real estate fund (i.e., Carlyle Partners II, Carlyle Realty
Partners II, Carlyle Realty Partners III, Carlyle Realty Partners IV and Carlyle Realty Partners V)
and not for breaches of representations made by any Contributor that is directly or indirectly
owned by any other real estate fund. Accordingly, the aggregate liability for any claims properly
asserted against all of the Contributors owned by any such fund shall be 10% of the aggregate OP
Unit Consideration received by all of the Contributors owned by such
fund (valuing such OP Units based upon the initial public offering price
of the Common Stock),




          (d) Notwithstanding anything contained herein to the contrary, before taking recourse against
any assets of the Contributors and subject to the limitations set forth in the following sentence,
the Indemnified Parties shall look, first to available insurance proceeds (including without
limitation any title insurance proceeds, if applicable) pursuant to Section 3.2(b) above, and then
to the Contributors’ OP Units pledged pursuant to the Pledge Agreement, for indemnification under
this Article 3, valuing such OP Units based upon the initial public offering price of the Common
Stock (and agree to treat any return of OP Units as an adjustment to the consideration delivered to
the Contributors pursuant to the Formation Transactions). Following the Closing and the issuance
of OP Units to the Contributors, no Indemnified Party shall have recourse to any other assets of
the Contributors other than the OP Units pursuant to the Pledge Agreement, and to the extent
applicable, any relevant title insurance policies, if any. Notwithstanding anything to the
contrary in this Agreement, the Contributors shall not be liable to the Indemnified Parties for any
indirect, special or consequential damages, loss of profits, loss of value or other similar
speculative damages asserted or claimed by the Indemnified Parties.




     3.6 Limitation Period.



          (a) Notwithstanding the foregoing, any claim for indemnification under Section 3.2 hereof must
be asserted in writing by the Indemnified Party, stating the nature of the Losses and the basis for
indemnification therefor on or prior to the first (1st) anniversary of the Closing.




          (b) Subject to Section 3.6(a), if asserted in writing on or prior to first (1st)
anniversary of the Closing, any claims for indemnification pursuant to Section 3.2 shall survive
until




Exhibit C-12 









 




resolved by mutual agreement between the Contributors and the Indemnified, and any claim for
indemnification pursuant to Section 3.2 not so asserted in writing on or prior to the first
(1st) anniversary of the Closing shall not thereafter be asserted and shall forever be
waived.

FORM OF PLEDGE AGREEMENT



     THIS PLEDGE AGREEMENT (this “Agreement”), dated as of September ___, 2010, is entered
into by and between CoreSite, L.P., a Delaware limited partnership (the “Operating
Partnership” or the “Pledgee”), and [__] (the “Pledgor”). Capitalized terms
used herein but not otherwise defined herein shall have the meanings assigned to such terms in the
Contribution Agreement (as defined below).



     WHEREAS, CoreSite Realty Corporation, a Maryland corporation (the “Company”), is the
sole general partner of the Operating Partnership;



     WHEREAS, pursuant to that certain Contribution Agreement, dated as of September ___, 2010, by
and among the Operating Partnership, the Company and the contributors named therein (including the
Pledgor) (the “Contribution Agreement”), the Pledgor is contributing all of its right,
title and interest in and to the Partnership Interests (as defined in the Contribution Agreement)
held by it to the Operating Partnership in exchange for OP Units;



     WHEREAS, the Pledgor has agreed to indemnify the Operating Partnership and the Company (each,
an “Indemnified Party”), as provided in Article 3 of Exhibit C to the Contribution
Agreement (and subject to the limitations expressed therein), for certain Losses asserted during
the Survival Period (as hereinafter defined). The Pledgor’s obligations (i) to indemnify the
Indemnified Parties for Losses in accordance with Article 3 of Exhibit C to the Contribution
Agreement, and (ii) to perform its obligations hereunder are referred to herein collectively as the
“Secured Obligations”; and



     WHEREAS, in order to secure the full and timely performance of the Secured Obligations
pursuant to the Contribution Agreement, the Pledgor has agreed to pledge and grant to the Pledgee
for the Pledgee’s own benefit and the benefit of each Indemnified Party, a lien and security
interest in, to and under a number of OP Units having a value equal to ten percent (10%) of such
Pledgor’s OP Unit Consideration, as more fully described on Exhibit A attached hereto (the
“Pledged Interests”), such pledge, lien and security interest to remain in effect during
the Pledge Period (as defined below).



     NOW, THEREFORE, in consideration of the premises and the mutual agreements herein contained,
and for good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:



     1. Grant of Security Interest. As collateral security for the payment, performance
and observance of the Secured Obligations, now existing or hereafter arising, absolute or
contingent, whether or not due and payable, the Pledgor pledges to the Pledgee, for its own benefit
and for the benefit of each Indemnified Party, and grants to the Pledgee, for its own
benefit and the benefit of each Indemnified Party, a security interest in the following
property (collectively, the “Collateral”):



 









 





          (a) the Pledged Interests, as more particularly described in Exhibit A attached hereto;




          (b) any additional partnership interests in the Operating Partnership (“Partnership
Interests”) and/or obligations of the Operating Partnership that may at any time hereafter be
acquired by any Pledgor in respect of the Pledged Interests and, if any, the certificates or other
instruments or documents evidencing the same;




          (c) all rights of Pledgor in and to all distributions in kind declared in respect of any or
all of the foregoing; and




          (d) all proceeds and profits of any or all of the foregoing.




     2. Delivery of Certificates and Instruments. The Pledgor shall deliver to the
Pledgee: (a) the original certificates or other instruments or documents evidencing the Pledged
Interests concurrently with the execution and delivery of this Agreement, and (b) the original
certificates or other instruments or documents evidencing all other Collateral (except for
Collateral that this Agreement specifically permits the Pledgor to retain) within ten (10) days
after a Pledgor’s receipt thereof. All Collateral that is certificated securities shall be in
bearer form or, if in registered form, shall be issued in the name of the Pledgee or endorsed to
the Pledgee or in blank. If any of the Collateral consists of uncertificated securities, the
Pledgee shall be entitled to indicate by book entry with the appropriate registrar (which may be
the Pledgee for any Pledged Interests) that such Collateral has been credited to the account of
Pledgee.



     3. Pledgor Remain Liable. Notwithstanding anything herein to the contrary: (a) the
Pledgor shall remain obligated, to the extent set forth in the agreements (including, without
limitation, the Contribution Agreement and the partnership agreement of Operating Partnership (the
“OP Agreement”)) under which it has received, or has rights or obligations in respect of
its ownership of, the Pledged Interests (“Related Agreements”) to perform its duties and
obligations thereunder to the same extent as if this Agreement had not been executed; (b) the
exercise by the Pledgee of any of its rights hereunder shall not release the Pledgor from any of
its duties or obligations under the Related Agreements, except to the extent that such duties and
obligations may have been terminated by reason of a sale, transfer or other disposition of the
Collateral pursuant hereto; and (c) the Pledgee shall not by reason of this Agreement have any
obligations or liabilities under the Related Agreements, nor shall the Pledgee be obligated to
perform any of the obligations or duties of the Pledgor under the Related Agreements or to take any
action to collect or enforce any claim for payment assigned hereunder.



     4. Representations, Warranties and Covenants. The Pledgor represents, warrants and
covenants, as of the date hereof (for itself and not jointly or jointly and severally with any
other Person), as follows:



          (a) Set forth on Exhibit A attached hereto is a complete and accurate list and description of
all Pledged Interests delivered by Pledgor. Pledgor owns, directly or indirectly, all






2









 







of such
Pledged Interests, free and clear of all claims, mortgages, pledges, liens, encumbrances and
security interests of every nature whatsoever, except in favor of the Pledgee. All other
Collateral hereafter delivered by the Pledgor to the Pledgee will be owned, directly or indirectly,
by the Pledgor free and clear of all claims, mortgages, pledges, liens, encumbrances and security
interests of every nature whatsoever, except in favor of the Pledgee.




          (b) With respect to the Pledgor, the address of its principal place of business, and the
location of its books and records relating to the Collateral, is set forth in Section 21 hereof.
Pledgor will not change said address or location, or merge or consolidate with any person or change
its name, without at least fifteen (15) days’ prior written notice to the Pledgee, and with respect
to any such change in address or name or merger or consolidation, Pledgor shall execute and deliver
to the Pledgee such documents and take such actions as the Pledgee reasonably deems necessary to
perfect and protect the Pledgee’s security interests in and to the Collateral.




          (c) During the Pledge Period (and, if and to the extent applicable, any Extended Pledge Period
(as defined below)), the Pledgor will not create, incur, assume or permit to exist any security
interest in the Collateral (or during such Extended Pledge Period, the Retained Collateral (as
defined below)) other than the security interest created pursuant to this Agreement or sell,
transfer, assign, pledge or grant a security interest in the Collateral (or during such Extended
Pledge Period, the Retained Collateral) to any person other than the Pledgee.




          (d) The Pledged Interests that are Collateral hereunder are fully paid and are not subject to
any options to purchase or similar rights of any kind granted by the Pledgor in favor of any
Person, except pursuant to the terms of the OP Agreement.




          (e) The Pledgor has the power and authority to own its properties and to carry on its business
as currently conducted.




          (f) The Pledgor has the requisite power and authority to execute and deliver, and to perform
its obligations under, this Agreement, and has taken all necessary action to authorize such
execution, delivery and performance.




          (g) This Agreement constitutes the legal, valid and binding obligation of the Pledgor,
enforceable against the Pledgor in accordance with its terms, except as such enforceability may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or
affecting the rights and remedies of creditors or by the application of general equitable
principles.




          (h) The Pledgor’s execution, delivery and performance of this Agreement will not violate (as
applicable) any law or regulation, or any order or decree of any court or governmental
instrumentality, or any provision of the certificate of formation or limited liability company
operating agreement of, or any securities issued by, the Pledgor, and will not conflict with, or
result in the breach of, or constitute a default under, any indenture, mortgage, deed of trust,
agreement or other instrument to which the Pledgor is a party or by which it is bound, and




3









 







will not
result in the creation or imposition of any lien, charge or encumbrance upon any of the property of
the Pledgor pursuant to the provisions of any of the foregoing.




          (i) No consent of any other Person (including, without limitation, as applicable, members and
creditors of the Pledgor) and no consent, license, permit, approval or authorization of, exemption
by, notice or report to, or registration, filing or declaration with, any governmental
instrumentality is required in connection with the execution, delivery, performance, validity or
enforceability of this Agreement, except for the filing of any financing statements required or
contemplated hereunder.




          (j) The pledge of the Collateral pursuant to this Agreement creates a valid and perfected
first priority security interest in such Collateral to the extent such interest can be created
pursuant to the Delaware Uniform Commercial Code, subject to any filings or actions required
pursuant to the Delaware Uniform Commercial Code or otherwise.




          (k) During the Pledge Period (and any Extended Pledge Period, if and to the extent
applicable), the Pledgor will take commercially reasonable actions to defend the Pledgee’s security
interest in the Collateral (or, during such Extended Pledge Period, the Retained Collateral)
against the claims and demands of all Persons whomsoever.




          (l) During the Pledge Period (and any Extended Pledge Period, if and to the extent
applicable), the Pledgor will take any and all commercially reasonable actions necessary to
maintain its status as a limited partner of the Operating Partnership and the limited liability
represented by the Pledged Interests.




          (m) During the Pledge Period, the Pledgor will not enter into or assume any other agreement
containing a negative pledge with respect to the Collateral (or, during any Extended Pledge Period,
if and to the extent applicable, with respect to the Retained Collateral).




     5. Registration. At any time and from time to time during the Pledge Period, the
Pledgee may cause all or any of the Collateral to be transferred to or registered in its name or
the name of its nominee or nominees.



     6. Claims; Value of Collateral.



          (a) Any claims by an Indemnified Party shall be made in accordance with Article 3 of Exhibit C
to the Contribution Agreement. On or prior to the first (1st) anniversary of the
Closing (the “Survival Period”), an Indemnified Party may give notice (a “Claim
Notice”) to
the Pledgor of any Loss that is subject to indemnification under Article 3 to Exhibit C of the
Contribution Agreement.




          (b) The value of Collateral (the “Value”) shall be determined as follows: (i) with
respect to Collateral consisting of OP Units, an amount equal to the initial public offering price
of shares of the Company’s common stock multiplied by the number of OP Units; and (ii) for all
other Collateral, the fair market value of such Collateral as determined by a majority of the




4









 







directors of the Company who meet the New York Stock Exchange standards of independence for
directors, and who are otherwise unaffiliated with the Pledgee the (“Independent
Directors”).




     7. Voting Rights and Certain Payments Prior to Occurrence of Secured Obligations and Other
Events.



          (a) Until Collateral may be applied to satisfy a Secured Obligation hereunder, the Pledgor
shall be entitled to exercise, in its sole discretion but not inconsistent with the terms hereof,
the voting power with respect to any such Collateral, and for that purpose the Pledgee shall (if
such Collateral shall be registered in the name of the Pledgee or its nominee) execute or cause to
be executed from time to time, at the expense of the Pledgor, such proxies or other instruments in
favor of the Pledgor or its nominee in such form and for such purposes as shall be reasonably
required and specified in writing by the Pledgor, to enable the Pledgor to exercise such voting
power with respect to such Collateral.




          (b) Until the Independent Directors of the Company reasonably determine that the outstanding
Claims asserted by the Indemnified Parties in one or more Claim Notices may equal or exceed the
value of the Collateral then available to satisfy such Claims, the Pledgor shall be entitled to
receive and retain for its own account any and all regular cash distributions (but not
distributions in the form of Partnership Interests or other securities, distributions in kind or
liquidating distributions, all of which shall be delivered and applied in accordance with Section 8
hereof) and interest at any time and from time to time paid upon any of such Collateral.




          (c) Notwithstanding anything contained in this Agreement to the contrary, except with the
prior consent of the Pledgee, until such time as the Pledge Period (or any Extended Pledge Period
as may be applicable) has expired, the Pledgor shall not have the right to exercise any of its
redemption rights under Section 15.1 of the OP Agreement with respect to any Pledged Interests.




     8. Extraordinary Payments and Distributions. In case, upon the dissolution or
liquidation (in whole or in part) of the Operating Partnership, any sum shall be paid as a
liquidating distribution or otherwise upon or with respect to any of the Collateral, such sum shall
be paid over to the Pledgee promptly, and in any event within ten days after receipt thereof, to be
held by the Pledgee as additional Collateral hereunder. In case any distribution of Partnership
Interests shall be made with respect to the Collateral, or Partnership Interests or fractions
thereof shall be issued pursuant to any split involving any of the Collateral, or any distribution
of capital
shall be made on any of the Collateral, or any partnership interests, shares, obligations or
other property shall be distributed upon or with respect to the Collateral pursuant to a
recapitalization or reclassification of the capital of the Operating Partnership, or pursuant to
the dissolution, liquidation (in whole or in part), bankruptcy or reorganization of the Operating
Partnership, or pursuant to the merger or consolidation of the Operating Partnership with or into
another entity, the partnership interests, shares, obligations or other property so distributed
shall be delivered to the Pledgee promptly, and in any event within ten days after receipt thereof,
to be held by the Pledgee as additional Collateral hereunder, and all of the same (other than cash)
shall constitute Collateral for all purposes hereof.

     9. Pledgor Obligations Not Affected. The obligations of the Pledgor hereunder shall
remain in full force and effect and shall not be impaired by:



          (a) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition,
liquidation or the like of the Pledgor;




          (b) any amendments to or modifications of any instrument (other than this Agreement) securing
any of the Secured Obligations;




          (c) the taking of additional security for, or any guaranty of, any of the Secured Obligations
or the release or discharge or termination of any security or guaranty for any of the Secured
Obligations; or




          (d) the lack of enforceability of any of the Secured Obligations against the Pledgor or any
other person, whether or not the Pledgor shall have notice or knowledge of any of the foregoing.




     10. Voting Rights and Certain Payments After Occurrence of Secured Obligation and Certain
Other Events.



          (a) At such time that Collateral may be applied to satisfy a Secured Obligation hereunder, all
rights of the Pledgor to exercise or refrain from exercising all voting power with respect to such
Collateral and to otherwise exercise all ownership rights arising from such Collateral shall cease,
and thereupon the Pledgee shall be entitled to exercise all voting power with respect to such
Collateral and otherwise exercise such ownership rights as though the Pledgee were the outright
owner of such Collateral. In the event that the Independent Directors of the Company reasonably
determine that the outstanding claims asserted by the Indemnified Parties in one or more Claim
Notices may equal or exceed the value of the Collateral then available to satisfy such claims, the
Pledgor shall no longer be the owner of such Collateral for tax purposes and all rights of the
Pledgor to receive and retain the distributions and interest which it would otherwise be authorized
to receive and retain pursuant to Section 7 hereof shall cease, and thereupon the Pledgee shall be
entitled to receive and retain, as additional Collateral hereunder, any and all distributions and
interest at any time and from time to time paid upon any
of such Collateral, provided that, concurrent with making such determination, the Pledgee
gives notice thereof to the Pledgor.




          (b) All payments, distributions or other property or assets that are received by the Pledgor
contrary to the provisions of paragraph (a) of this Section 10 shall be received and held in trust
for the benefit of the Pledgee, shall be segregated from other funds of the Pledgor and shall be
forthwith paid over to the Pledgee.




     11. Application of Cash Collateral. Any cash received and retained by the Pledgee as
additional Collateral pursuant to Section 8 hereof may at any time and from time to time be applied
(in whole or in part) by the Pledgee, at its option, to the payment of the Secured



6









 




Obligations
which such Collateral secures (in such order as the Pledgee shall in its sole discretion
determine), if and to the extent any such payment is required hereunder.




     12. Application of Proceeds. Except as otherwise expressly provided herein, any cash
received and retained pursuant to Section 8 hereof shall be applied by the Pledgee: first to the
payment in full of the Secured Obligations, if and to the extent any such payment is required
hereunder; and then, to the payment to the Pledgor, or its successors or assigns or as a court of
competent jurisdiction may direct, of any surplus then remaining.



     13. Remedies With Respect to the Collateral.



          (a) If the Pledgor fails to pay or perform any Secured Obligation when due, the Pledgee,
without obligation to resort to other security, shall have the right at any time and from time to
time to receive all or any part of Collateral with a Value equal to the amount of such Secured
Obligation, in one or more parcels at the same or different times, and all right, title and
interest, claim and demand therein and right of redemption thereof.




          (b) Notwithstanding anything to the contrary in this Agreement (or the Contribution
Agreement), the sole recourse of the Pledgee against the Pledgor for the Secured Obligations and
the obligations of the Pledgor under this Agreement is limited to the rights of the Pledgor in any
such Collateral that is applied to satisfy a Secured Obligation.




          (c) No demand, advertisement or notice, all of which are hereby expressly waived, shall be
required in connection with any transfer of Collateral to the Pledgee pursuant to this Agreement.




          (d) Subject to the provisions of Section 13(b), the remedies provided herein in favor of the
Pledgee shall not be deemed exclusive, but shall be cumulative, and shall be in addition to all
other remedies in favor of the Pledgee existing at law or in equity.




          (e) Pledgor and Pledgee agree to treat any application of Pledged Interests in discharge of
any Secured Obligations as a non-taxable adjustment to the portion of the consideration received by
the Pledgor pursuant to the Contribution Agreement in the form of
Partnership Units unless otherwise required pursuant to a “determination” within the meaning
of Section 1313(a) of the Internal Revenue Code of 1986, as amended.




     14. Care of Collateral. The Pledgee shall have no duty as to the collection or
protection of the Collateral or any income thereon or as to the preservation of any rights
pertaining thereto, beyond the safe custody of any thereof actually in its possession. With
respect to any maturities, calls, conversions, exchanges, redemptions, offers, tenders or similar
matters relating to any of the Collateral (herein called “events”), the Pledgee’s duty shall be
fully satisfied if (i) the Pledgee exercises reasonable care to ascertain the occurrence and to
give reasonable notice to the Pledgor of any events applicable to any Collateral which are
registered and held in the name of the Pledgee or its nominee, (ii) the Pledgee gives the Pledgor
reasonable notice of the occurrence of any events, of which the Pledgee has received actual
knowledge, as to



7









 




any securities which are in bearer form or are not registered and held in the name
of the Pledgee or its nominee (the Pledgor agreeing to give the Pledgee reasonable notice of the
occurrence of any events applicable to any securities in the possession of the Pledgee of which the
Pledgor have received knowledge), and (iii) (a) the Pledgee endeavors to take such action with
respect to any of the events as the Pledgor may reasonably and specifically request in writing in
sufficient time for such action to be evaluated and taken or (b) if the Pledgee reasonably
determines that the action requested might adversely affect the value of the Collateral, the
collection of the Secured Obligations, or otherwise prejudice the interests of the Pledgee, the
Pledgee gives reasonable notice to the Pledgor that any such requested action will not be taken and
if the Pledgee makes such determination or if the Pledgor fails to make such timely request, the
Pledgee takes such other action as it deems advisable in the circumstances. Except as hereinabove
specifically set forth, the Pledgee shall have no further obligation to ascertain the occurrence
of, or to notify the Pledgor with respect to, any events and shall not be deemed to assume any such
further obligation as a result of the establishment by the Pledgee of any internal procedures with
respect to any Collateral in its possession. Except for any claims, causes of action or demands
arising out of the Pledgee’s failure to perform its agreements set forth in this Section, the
Pledgor releases the Pledgee from any claims, causes of action and demands at any time arising out
of or with respect to this Agreement, the Collateral and/or any actions taken or omitted to be
taken by the Pledgee with respect thereto, and the Pledgor hereby agrees to hold the Pledgee
harmless from and with respect to any and all such claims, causes of action and demands.




     15. Power of Attorney. The Pledgor hereby appoints the Pledgee to act during the
Pledge Period (and, if and to the extent applicable, any Extended Pledge Period) as the Pledgor’s
attorney-in-fact for the purpose of carrying out the provisions of this Agreement and taking any
action and executing any instrument that the Pledgee reasonably may deem necessary or advisable to
accomplish the purposes hereof. Without limiting the generality of the foregoing, during the
Pledge Period (and, if and to the extent applicable, any Extended Pledge Period), the Pledgee shall
have the right and power (a) upon application of any Collateral (including, during such Extended
Pledge Period, any Retained Collateral) to satisfy a Secured Obligation, to receive, endorse and
collect all checks and other orders for the payment of money made payable
to the Pledgor representing any interest or other distribution payable in respect of such
Collateral (or Retained Collateral) or any part thereof and to give full discharge for the same,
and (b) to execute endorsements, assignments or other instruments of conveyance or transfer with
respect to all or any of the Collateral (or Retained Collateral); provided, that the
Pledgee shall provide written notice to the Pledgor reasonably prior to taking any such action
under the foregoing clauses (a) and (b).



     16. Further Assurances. The Pledgor shall, at its sole cost and expense, upon request
of the Pledgee, duly execute and deliver, or cause to be duly executed and delivered, to the
Pledgee such further instruments and documents and take and cause to be taken such further actions
as may be necessary or proper in the reasonable opinion of the Pledgee to carry out more
effectually the provisions and purposes of this Agreement.

     17. No Waiver. No failure on the part of the Pledgee to exercise, and no delay on the
part of the Pledgee in exercising, any of its options, powers, rights or remedies hereunder, or
partial or single exercise thereof, shall constitute a waiver thereof or preclude any other or
further exercise thereof or the exercise of any other option, power, right or remedy.



     18. Security Interest Absolute. All rights of the Pledgee hereunder, grant of a
security interest in the Collateral and all obligations of the Pledgor hereunder, shall be absolute
and unconditional irrespective of (a) any lack of validity or enforceability of the Contribution
Agreement, any of the Secured Obligations or any other agreement or instrument relating thereto,
(b) any change in any term of all or any of the Secured Obligations or any other amendment or
waiver of, or any consent to any departure from, the Contribution Agreement or any other agreement
or instrument or (c) any other circumstance that might otherwise constitute a defense available to,
or a discharge of the Pledgor in respect of the Secured Obligations or in respect of this
Agreement.



     19. Expenses. Pledgor agrees to pay the Pledgee all reasonable out-of-pocket expenses
of the Pledgee (including reasonable expenses for legal services of every kind) of, or incident to
the enforcement of, any provisions of this Agreement.



     20. End of Pledge Period; Return of Collateral.



          (a) For purposes of this Agreement, the “Pledge Period” means the period beginning on
the date hereof and ending upon the termination of the Survival Period; provided, that, if
any claim(s) asserted in any Claim Notices(s) remain outstanding at the time of termination of the
Survival Period (any such claim, an “Outstanding Claim”), the Pledgee shall have the right
to retain, pending resolution of such Outstanding Claim(s) pursuant to Article 3 of Exhibit C to
the Contribution Agreement, and at all times subject to the terms hereof, Collateral with a Value
equal to the aggregate dollar amount of such Outstanding Claims (“Retained Collateral”)
and, solely with respect to such Retained Collateral, the Pledge Period shall be deemed to continue
(an “Extended Pledge Period”) until the resolution pursuant to Article 3 of
Exhibit C to the Contribution Agreement, of the Outstanding Claim(s) to which such Retained
Collateral relates.




          (b) Upon the termination of the Pledge Period (or the Extended Pledge Period, if and to the
extent applicable), the Pledgor shall be entitled to, and the Pledgee promptly shall effect, the
return to the Pledgor of all of the Collateral (and all other cash held as additional Collateral
hereunder) that has not been used or applied toward the payment of the Secured Obligations in
accordance with the terms hereof (it being understood, for the sake of clarity, that all Collateral
not so used or applied shall become subject to the foregoing return obligation on and as of the
Survival Date, except for any Retained Collateral, which shall become subject to the foregoing
return obligation on and as of the date on which the Outstanding Claim(s) related thereto are
resolved in accordance with Article 3 of Exhibit C to the Contribution Agreement). The Pledgee
shall take all reasonable actions to effect and evidence the return of Collateral under this
Section 20, including, without limitation, the filing of UCC termination statements (if



9









 






applicable)
with respect to, and the return to the Pledgor of certificates representing the Pledged Interests
comprising, such Collateral.




          (c) The assignment by the Pledgee to the Pledgor of such Collateral shall be without
representation or warranty of any nature whatsoever and wholly without recourse. Notwithstanding
the foregoing, the Pledgor’s release of the Pledgee and agreement to hold the Pledgee harmless set
forth in the last sentence of Section 14 hereof shall survive any return of Collateral or
termination of this Agreement.




     21. Notices. All notices and other communications in connection with this Agreement
shall be made in writing by hand delivery, registered first-class mail, telex, telecopier, or air
courier guaranteeing overnight delivery:

the Pledgor hereunder shall be construed in accordance with and governed by the law of the State of
New York (without giving effect to the conflict-of-laws principles thereof).



     24. Transfer or Assignment. Except with respect to any assignment or transfer by the
Pledgee to an affiliate (which shall not require the Pledgor’s consent but as to which the Pledgee
will give prior written notice to the Pledgor), none of the Pledgor or Pledgee may assign or
transfer any of their respective rights under and interests in this Agreement without the prior
written consent of the Pledgor (if the assignor/transferee is the Pledgee) or of the Pledgee (if
the



10









 




assignor/transferee is the Pledgor), which consent shall not be unreasonably withheld or
delayed; provided, however, that no consent of the Pledgor is required hereunder
for (a) the assignment or transfer by the Operating Partnership of any of its rights under and
interests in the Contribution Agreement to any permitted assignee under the Contribution Agreement
or (b) the Pledgee to act hereunder as agent on behalf of any person who becomes a Indemnified
Party. Upon receipt of such consent (if required under this Section 24), the Pledgee may deliver
the Collateral or any portion thereof to its assignee/transferee who shall thereupon, to the extent
provided in the instrument of assignment, have all of the rights and obligations of the Pledgee
hereunder with respect to the Collateral, and the Pledgee shall thereafter be fully discharged from
any responsibility with respect to the Collateral so delivered to such assignee/transferee.
However, no such assignment or transfer shall relieve such assignee/transferee of those duties and
obligations of the Pledgee specified hereunder.




     25. Benefit of Agreement. This Agreement shall be binding upon and inure to the
benefit of the Pledgor and the Pledgee and their respective heirs, successors and permitted
assigns, and all subsequent holders of the Secured Obligations.



     26. Counterparts. This Agreement may be executed in any number of counterparts and by
the different parties hereto on separate counterparts, each of which when so executed and delivered
shall be an original and all of which shall together constitute one and the same agreement.



     27. Captions. The captions of the sections of this Agreement have been inserted for
convenience only and shall not in any way affect the meaning or construction of any provision of
this Agreement.



     28. Complete Agreement. This Agreement and the Contribution Agreement, as applicable,
constitute the entire agreement of the parties with respect to the subject matter hereof and
supersede all other understandings, oral or written, with respect to the subject matter hereof.



     29. Severability. In case any one or more of the provisions contained in this
Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein shall not in any way be affected or
impaired.



     31. No Third-Party Beneficiaries. Except as may be expressly provided or incorporated
by reference herein, no provision of this Agreement is intended, nor shall it be interpreted, to
provide or create any third party beneficiary rights or any other rights of any kind in any
customer, affiliate, stockholder, partner, member, director, officer or employee of any party
hereto or any other Person or entity.
