         the period of Borrower's ownership of the Property; and to the best of
         Borrower's knowledge without inquiry, no such use on any adjacent
         property occurred at any time prior to the date hereof;

         Property by reason of any Environmental Requirement.

3.  VIOLATIONS. Borrower will not cause, commit, permit or allow to continue (i)

    or additional storage tanks (or similar vessel) on the Property and will
    keep the Property free of Hazardous Material.

Notwithstanding the foregoing provisions of this Section 3, Borrower shall not
be in Default under this Section 3 should Borrower store minimal quantities of
substances on the Property which technically could be considered Hazardous
Material, provided that: such substances are of a type and are held only in a
quantity normally used in connection with the construction, occupancy or
operation of comparable buildings (such as cleaning fluids, and supplies
normally used in the day to day operation of business offices), such substances
are being held, stored and used in complete and strict compliance with all
applicable Environmental Requirements, and the indemnity in Section 7 of this
Agreement shall always apply to such substances, and it shall be and continue to

4.  NOTICE TO LENDER. Borrower shall promptly deliver to Lender a copy of each
    report pertaining to the Property prepared by or on behalf of Borrower
    pursuant to any Environmental Requirement. Borrower shall immediately advise
    Lender in writing of any Environmental Claim or of the discovery of any
    Hazardous Material on the Property, as soon as Borrower first obtains
    knowledge thereof, including a full description of the nature and extent of
    the Environmental Claim and/or Hazardous Material and all relevant
    circumstances.

5.  SITE ASSESSMENTS AND INFORMATION. If Lender shall ever have a reasonable
    basis to believe that any Hazardous Material affects the Property (other
    than materials described in the Report), or if any Environmental Claim is
    made or threatened, or if a Default (as defined in the Mortgage) shall have
    occurred under the Documents, or upon the occurrence of the Release Date
    (hereinafter defined) if requested by Lender, Borrower shall at its expense,
    provide to Lender from time to time, in each case within sixty (60) days
    after Lender's request, an Environmental Assessment (hereinafter defined)
    made after the date of Lender's request. As used in this Agreement, the term
    "Environmental Assessment" means a report (including all drafts thereof) of
    an environmental assessment of the Property of such scope (including but not
    limited to the taking of soil borings and air and groundwater samples and
    other above and below ground testing) as Lender may request, by a consulting
    firm acceptable to Lender and made in accordance with Lender's established
    guidelines. Borrower will cooperate with each consulting firm making any
    such Environmental Assessment and will supply to the consulting firm, from
    time to time and promptly on request, all information available to Borrower
    to facilitate the completion of the Environmental Assessment. If Borrower
    fails to furnish Lender within thirty (30) days after Lender's request with
    a copy of an agreement with an acceptable environmental consulting firm to
    provide such Environmental Assessment, or if Borrower fails to furnish to
    Lender such Environmental Assessment within sixty


                                      -3-
   4

    (60) days after Lender's request, Lender may cause any such Environmental
    Assessment to be made at Borrower's expense and risk. Lender and its
    designees are hereby granted access to the Property at any time or times,
    upon reasonable notice (which may be written or oral), and a license which
    is coupled with an interest and irrevocable, to make or cause to be made
    such Environmental Assessments, Lender may disclose to interested parties
    any information Lender ever has about the environmental condition or
    compliance of the Property, but shall be under no duty to disclose any such
    information except as may be required by law. Lender shall be under no duty
    to make any Environmental Assessment of the Property, and in no event shall
    any such Environmental Assessment by Lender be or give rise to a
    representation that any Hazardous Material is or is not present on the
    Property, or that there has been or shall be compliance with any
    Environmental Requirement, nor shall Borrower or any other person be
    entitled to rely on any Environmental Assessment made by Lender or at
    Lender's request. Lender owes no duty of care to protect Borrower or any
    other person against, or to inform them of, any Hazardous Material or other
    adverse condition affecting the Property.

6.  REMEDIAL ACTIONS.

    (a)  If any Hazardous Material is discovered on the Property at any time and
         regardless of the cause, (i) Borrower shall promptly at Borrower's sole
         risk and expense remove (or encapsulate in accordance with customary
         remediation practices), treat, and dispose of the Hazardous Material in
         compliance with all applicable Environmental Requirements and solely
         under Borrower's name (or if removal is prohibited by any Environmental
         Requirement, take whatever action is required by any Environmental
         Requirement), in addition to taking such other action as is necessary
         to have the full use and benefit of the Property as contemplated by the
         Documents, and provide Lender with satisfactory evidence thereof; and
         (ii) if requested by Lender, provide to Lender within thirty (30) days
         of Lender's request a bond, letter of credit or other financial
         assurance evidencing to Lender's satisfaction that all necessary funds
         are readily available to pay the costs and expenses of the actions
         required by clause (i) preceding and to discharge any assessments or
         liens established against the Property as a result of the presence of
         the Hazardous Material on the Property. Within fifteen (15) days after
         completion of such remedial actions, Borrower shall obtain and deliver
         to Lender an Environmental Assessment of the Property made after such
         completion and confirming to Lender's satisfaction that all required
         remedial action as stated above has been taken and successfully
         completed and that there is no evidence or suspicion of any
         contamination or risk of contamination on the Property or any adjacent
         property, or of violation of any Environmental Requirement, with
         respect to any such Hazardous Material.

    (b)  Lender may, but shall never be obligated to, remove or cause the
         removal of any Hazardous Material from the Property (or if removal is
         prohibited by any Environmental Requirement, take or cause the taking
         of such other action as is required by any Environmental Requirement)
         if Borrower fails to promptly commence such remedial actions following
         discovery and thereafter diligently prosecute the same to the
         satisfaction of Lender (without limitation of Lender's rights to
         declare a default under any of the Documents and to exercise all rights
         and remedies available by reason thereof); and Lender and its designees
         are hereby granted access to the Property at any time or times, upon
         reasonable notice (which may be written or oral), and a license which
         is coupled with an interest and irrevocable, to remove or cause such
         removal or to take or cause the taking of any such other action.

         to a particular Indemnified Party to the extent that the subject of the
         indemnification is caused by or arises out of the negligence or willful
         misconduct of that particular Indemnified Party. Upon demand by Lender,
         Borrower shall diligently defend any Environmental Claim which affects
         the Property or is made or commenced against Lender, whether alone or
         together with any other person, all at Borrower's own cost and expense
         and by counsel to be approved by Lender in the exercise of its
         reasonable judgment. In the alternative, at any time Lender may elect

   6

    and regardless of whether any of the foregoing subparagraphs (1) through (5)

    Property or its tenant or subtenant, or any third party, including but not

         Purchaser or grantee free of occupancy and claims to occupancy by
         Borrower and its heirs, devisees, representatives, successors and
         assigns; provided that, if such payment, performance, release,
         foreclosure or conveyance is challenged, in bankruptcy proceedings or
         otherwise, the Release Date shall be deemed not to have occurred until
         such challenge is validly released, dismissed with prejudice or
         otherwise barred by law from further assertion.

8.  CONSIDERATION; SURVIVAL; CUMULATIVE RIGHTS. Borrower acknowledges that
    Lender has relied and will rely on the representations, warranties,
    covenants and agreements herein in closing and funding the Loan and that the
    execution and delivery of this Agreement is an essential condition but for
    which Lender would not close or fund the Loan. The representations,
    warranties, covenants and agreements in this Agreement shall be binding upon
    Borrower and its successors, assigns and legal representatives and shall
    inure to the benefit of Lender and its successors, assigns and legal
    representatives and participants in the Loan; and shall not terminate on the
    Release Date or upon the release, foreclosure or other termination of the
    Mortgage, but will survive the Release Date, the payment in full of the
    indebtedness secured by the Mortgage, foreclosure of the Mortgage or
    conveyance in lieu of foreclosure, the release or termination of the
    Mortgage and any and all of the other Documents, any investigation by or on
    behalf of the Lender, any bankruptcy or other debtor relief proceeding, and
    any other event whatsoever. Any amount to be paid under this Agreement by
    Borrower shall be a demand obligation owing by Borrower (which Borrower
    hereby promise to pay). Lender's rights under this Agreement shall be in
    addition to all rights of Lender under the Documents or at law or in equity,
    under this Agreement shall be in addition to all rights of Lender under the
    Documents or at law or in equity, and payments by Borrower under this
    Agreement shall not reduce Borrower's obligation and liabilities under any
    of the Documents. The liability of Borrower or any other person under this
    Agreement shall not be limited or impaired in any way by any provision in
    the Documents or applicable law limiting Borrower's or such other person's
    liability or Lender's recourse or rights to a deficiency judgment, or by any
    change, extension, release, inaccuracy, breach or failure to perform by any
    party under the Documents, Borrower's (and, if applicable, such other
    person's) liability hereunder being direct and primary and not as a
    guarantor or surety. Borrower hereby assigns and irrevocably transfers to
    Lender any and all


                                       -6-
   7

    rights of subrogation, contribution, indemnification, reimbursement or
    similar rights it may have against Borrower or any other person for
    Environmental Damages. Nothing in this Agreement or in any other Loan
    Document shall limit or impair any rights or remedies of Lender, Trustee
    and/or any other Indemnified Party against Borrower or any other person
    under any Environmental Requirement or otherwise at law or in equity,
    including without limitation, any rights of contribution or indemnification.

9.  NO WAIVER. No delay or omission by Lender to exercise any right under this
    Agreement shall impair any such right nor shall it be construed to be a
    waiver thereof. No waiver of any single breach or Default under this
    Agreement shall be deemed a waiver of any other breach or Default. Any
    waiver, consent or approval under this Agreement must be in writing to be
    effective.

    required or which any party desires to give hereunder or under any other

    unenforceable or invalid shall not affect the enforceability or validity of
    any other provision and a determination that the application of any
    provision of this Agreement to any person or circumstance is illegal or

    provision as it may apply to other persons or circumstances.

    parties waives trial by jury in any court action or proceeding to which
    Borrower and Lender may be parties, arising out of, in connection with or in
    any way pertaining to, this instrument or any other documents evidencing or
    securing the loan transaction herein involved. It is agreed and understood
    that this waiver constitutes a waiver of trial by jury of all claims against
    all parties to such action or proceedings, including claims against parties

    willingly and voluntarily made by each of the parties, and each of the
    parties hereby represents that no representations of fact or opinion have
    been made by any individual to induce this waiver of trial by jury or to in
    any way modify or nullify its effect. Each of the parties further represents
    and warrants that it has been represented in the signing of this instrument
    and in the making of this waiver by independent legal counsel, or has had
    the opportunity to be represented by independent legal counsel selected of
    its own free will, and that it has had the opportunity to discuss this
    waiver with counsel. Each of the parties agree and consent that the other
    party may file an original counterpart or a copy of this document with any
    court as written evidence of the consent of each of the other parties to the
    waiver of its right to trial by jury.

14. SERVICE OF PROCESS. Borrower hereby waives personal service and consents to
    process being served in any suit, action, or proceeding instituted in
    connection with this instrument or the Documents by (i) the mailing of a
    copy thereof by certified mail, postage prepaid, return receipt requested,
    to Borrower at its address set forth on the signature page hereof and
    service so made shall be deemed to be completed five (5) days after the same
    shall have been so deposited in the U.S. Mail, or (ii) at Lender's option by
    serving a copy thereof upon Borrower. Borrower irrevocably agrees that such
    service shall be deemed to be service of process upon Borrower in any such
    suit, action, or proceeding. Nothing in this document shall affect the right
    of Lender to serve process in any manner otherwise permitted by law and
    nothing in this Note will limit the right of Lender otherwise to bring
    proceedings against Borrower in the courts of any jurisdiction or
    jurisdictions.

15. EXECUTION; MODIFICATION. This Agreement may be executed in a number of
    identical counterparts, each of which shall be deemed an original for all
    purposes and all of which constitute, collectively, one agreement. This
    Agreement may be amended only by an instrument in writing intended for that
    purpose executed jointly by an authorized representative of each party
    hereof.
