true and correct in all material respects; and


                                       12

<PAGE>



          (o) The proposed Transfer shall be subject to and shall comply with
all of the terms and conditions of the Loan Application (provided, however, that
in the event of a direct conflict between the terms of the Loan Application and
the terms of the Loan Documents, the terms of the Loan Documents shall control),

Lender but not later than the Transfer Date and whether or not Borrower

title insurance premiums (including all costs for endorsements to existing
mortgagee's title policy or policies insuring the Liens of the Security Deed, as

be deemed to constitute part of the Obligations.

     Section 3.4 Lender's Obligations. Lender agrees to exercise good faith in
reviewing all documentation it deems necessary to determine whether the proposed
Transferee is or is controlled by or under common control with a Qualified Real
Estate Investor. Lender shall notify Borrower within sixty (60) days after
Lender's receipt of all such documentation and information whether the
Transferee has been approved.

                   ARTICLE 4 - Representations and Warranties
                               ------------------------------

     Section 4.1 Representations and Warranties. The representations, warranties
and releases set forth below shall be deemed to be made as of the date each
Request for Release or Request for Transfer is delivered to Lender, and as of

made under this Agreement shall survive, and not be waived by, the Release or
Transfer of any Parcel pursuant to this Agreement.

          (a) Litigation. Borrower represents, warrants and covenants that there

of any kind or before or by any governmental body, which action, suit,
proceeding or investigation (i) calls into question the validity of this
Agreement or any other Loan Document or any New Loan Document, or (ii) could, if
determined adversely to Borrower, the Remaining Property, the Transferred
Property or the Non-Transferred Property, have a Material Adverse Effect.


                                       13

<PAGE>



          (b) Taxes. Borrower represents, warrants and covenants that all
Impositions required to be paid by Borrower which are due and payable, have been
paid, except any such Imposition the payment of which Borrower is contesting in
good faith by proper legal action in accordance with the terms and conditions of
the Security Deed.

          (c) Financial Statements. Borrower represents, warrants and covenants
that all financial statements, cash flow statements and other information which
Borrower has furnished or caused to be furnished to Lender to enable the Lender
to determine the compliance of Borrower with the applicable conditions precedent
to a Release, as set forth in Article 2 hereof, or a Transfer, as set forth in

date thereof.

          (d) Governmental Regulation. Borrower represents, warrants and

Transfer, as the case may be.

                        ARTICLE 5 - Additional Agreements
                                    ---------------------

     Section 5.1 Additional Agreements. Notwithstanding anything in the other
Loan Documents to the contrary, Lender and Borrower hereby agree as follows
(which agreements shall inure solely to the benefit of Lender, its successors
and assigns, and Borrower and not to the benefit of any Transferee [other than a
Beacon Affiliate to whom all of the Property is transferred in accordance with
Section 3.03(a) of the Security Deed]):

          (a) So long as no Event of Default exists, Borrower shall be entitled
to settle, adjust or compromise any claims for loss, damage or destruction to
the Property under the following conditions: (i) Borrower shall allow Lender and
Lender's representatives to participate in all settlement, adjustment or
compromise negotiations, (ii) Borrower shall employ attorneys and consultants
for such purposes acceptable to Lender, and (iii) Borrower shall not agree to or
finalize any settlement, adjustment or compromise of any claim without the prior
written consent of Lender, which consent shall not be unreasonably withheld or
delayed.

          (b) All Small Insurance Proceeds received by Lender shall be delivered
to Borrower, unless at the time the Small Insurance Proceeds are to be delivered
to Borrower there exists an Event of Default, in which event Lender shall have
no obligation to deliver the Small Insurance Proceeds to Borrower, and Lender
shall be entitled (but not obligated) to retain and apply the Small Insurance
Proceeds in reduction of the indebtedness evidenced by the Note. All Small
Insurance Proceeds delivered to Borrower shall be held by Borrower in a separate
account designated only for the Restoration, and shall be disbursed only for
costs and expenses related to the Restoration for which the Small Insurance
Proceeds were paid. In the event that the estimated cost of Restoration exceeds
the amount of the Small Insurance

                                       14

<PAGE>



Proceeds, the initial cost of such Restoration shall be paid from other sources
until such time as the amount held in the designated account is sufficient to
pay the cost of the remaining Restoration in full, after which time funds may be
disbursed from such account for the remaining costs and expenses of the
Restoration. It is the intent of the parties that except where costs and
expenses may initially be paid from another source, there shall always be
sufficient funds in the designated account to pay the costs and expenses related
to the Restoration; however, the foregoing shall not limit the obligation of
Borrower to cause the Restoration to be completed in accordance with the
Requirements and all costs and expenses related thereto to be paid, whether or
not there are sufficient funds in such designated account. As to Restoration
relating to damage or destruction covered by Small Insurance Proceeds, Borrower
shall not be obligated to comply with the Requirements for Restoration set forth
in the Security Deed. Upon completion of the Restoration and the payment of all
costs and expenses related to such Restoration, provided that there is no Event
of Default, any funds remaining in such designated account for the Restoration
shall be funds of Borrower free from the foregoing restrictions and obligations.

          (c) Upon the occurrence of an Event of Default, Borrower shall deliver
to Lender all Small Insurance Proceeds then held by Borrower and Lender may
apply such amounts to the reduction of the indebtedness evidenced by the Note.

          (d) All Insurance Proceeds received by Lender and held by Lender
pending completion of the Work pursuant to the Security Deed shall be held in an
interest bearing account and such interest shall be held and utilized in the
same manner as Insurance Proceeds.

          (e) Borrower may acquire fixtures, equipment or other property forming
a part of the Property pursuant to a lease, license, title retention document or
similar agreement without Lender's express written approval, if the aggregate
annualized amount payable by Borrower under all such leases, licenses, title
retention documents or similar agreements is less than $100,000.00.

          (f) The personal liability of Beacon Properties, L.P. or of a Beacon
Affiliate to whom the Property is transferred pursuant to Section 3.03(a) of the
Security Deed, as the case may be, and their respective general partners, under
Section 1.17 of the Security Deed for damages arising from, or in connection
with, a breach of any of the covenants, obligations, liabilities, warranties and
representations contained in Section 3.08 of the Security Deed, shall not
include damages for diminution in the market value of the Property resulting
from a release or discharge of Hazardous Materials onto the Property caused by a
person or entity other than Beacon Properties, L.P. or a Beacon Affiliate.

          (g) With respect to the Transferred Property, Borrower's personal
liability under the Unsecured Indemnity Agreement and under Section 3.08 of the
Security Deed shall be terminated for those releases, discharges or spills of
Hazardous Materials or other environmental conditions arising or occurring
subsequent to the Transfer of the Transferred Property if, in connection with
the Transfer, a Qualified Real Estate Investor executes in favor

                                       15

<PAGE>



of Lender an unsecured indemnity agreement in substantially the same form as the
Unsecured Indemnity Agreement and executes additional documentation causing such
Qualified Real Estate Investor to be bound by the recourse obligations set forth
in the security deed executed by the Transferee in favor of Lender or assumed by
the Transferee.

          (h) The surety bond referenced in Subparagraph (a)(v) of Exhibit "D"
to the Security Deed shall be required only if the total estimated cost of
completing the Work is more than $500,000.00.

          (i) With respect to the Unsecured Indemnity Agreement, Section 3(a)
shall be deemed to read as follows:

               "In any circumstance in which this Agreement applies,
           Indemnitor shall employ counsel and consultants approved by
           Lender (such approval not to be unreasonably withheld) to
           investigate, prosecute, negotiate, or defend any Environmental
           Claim until resolution. In the event that a conflict or
           dispute arises between Indemnitor and Lender that cannot be
           settled through informal negotiation, Lender shall have the
           right to employ its own counsel and/or consultants, whose fees
           and expenses shall be paid by Indemnitor upon Lender's demand.
           Indemnitor shall reimburse Lender, upon demand, for all Costs
           incurred by Lender, including the amount of all Costs of
           settlements entered into by Lender, provided such settlements
           are approved by Indemnitor, which approval shall not be
           unreasonably withheld or delayed."

          (j) With respect to the Unsecured Indemnity Agreement, the term
"Costs" as used therein shall not include diminution in the market value of all
or any portion of the Property resulting from a release or discharge of
Hazardous Materials onto the Property or any portion thereof caused by a person
or entity other than Beacon Properties, L.P. or a Beacon Affiliate (such a
release or discharge is referred to herein as a "Third-Party Release"); however,
in the event of a Third-Party Release, "Costs" shall include all other (that is
other than diminution in the market value of the Property) liabilities, losses,
costs, damages, expenses, claims, fees and disbursements, including without
limitation, remedial, removal, response, abatement, cleanup, legal investigative
and monitoring costs and related costs, expenses, losses, damages, penalties,
fines, obligations, defenses, judgments, suits, proceedings and disbursements.

          (k) Upon the application of any Condemnation Proceeds to the reduction
of the indebtedness evidenced by the Note, the monthly installments of principal
and interest due under the Note shall be adjusted in the same manner as such
installments are to be adjusted in the event of a partial prepayment under
Section 1 of the Note.


                                       16

<PAGE>



          (l) Clause (4) of Subsection 1.07(b) of the Security Deed is deemed to
be amended to read as follows:

                    "(4) Grantor (A) shall secure and protect the
           Improvements remaining on the damaged portion of the Property,
           (B) shall endeavor diligently to satisfy all conditions and
           requirements of this Security Deed regarding the utilization
           of the Net Insurance Proceeds for the Restoration, and (C)
           within one hundred eighty (180) days after the occurrence of
           the damage or destruction to the Property requiring
           Restoration, shall submit to Grantee and receive Grantee's
           approval (which approval shall not be unreasonably withheld or
           delayed) of the plans and specifications for such Restoration
           and shall deposit with Grantee the additional amount necessary
           to accomplish the Restoration as provided in subparagraph (a)
           of the Requirements for Restoration."

          (m) Section 1.07(b) of the Security Deed is deemed to be amended by
adding the following language to the end of the last sentence thereof:

           "; provided, however, if less than twenty-five (25%) percent
           of the Improvements (as measured by the net leasable area of
           all Improvements) is damaged or destroyed, and Grantee intends
           to declare the entire Secured Indebtedness immediately due and
           payable, Grantee shall give Grantor written notice of such
           intent (the "Notice of Intent") and shall forbear from
           exercising its right to accelerate the Loan (as defined in the
           Loan Agreement) if the following conditions are met:

               (i) Grantor delivers to Grantee, no later than ten (10) business
days after the effective date of the Notice of Intent, a Request for Release in
accordance with the terms and conditions set forth in the Loan Agreement,
requesting the release of the parcel or parcels on which the damaged or
destroyed portions of the Improvements are situated;

               (ii) No later than ninety (90) days after the Request for Release
is submitted to Grantee, Grantor satisfies all of the conditions and
requirements for such Release under the Loan Agreement except for the conditions
set forth in Section 2. I (a) and (b) of the Loan Agreement, which requirements
are hereby waived by Grantee with respect to such Release; and

               (iii) the Release Amount is paid to Grantee on the Release Date
(it being agreed by Grantee that the Net Insurance Proceeds arising out of the
damage or destruction to the Improvements on the parcel or parcels being
Released may be applied towards the Release Amount)."

                                       17

<PAGE>



and by adding the following new sentence to the end of Section 1.07(b):

         "Notwithstanding the foregoing, in the event of damage or
         destruction to Building 64A, Building 301/303, the North
         Terraces Building or the South Terraces Building (as such
         Buildings are identified in Schedule 1 to the Loan Agreement)
         which does not render untenantable or unusable more than
         twenty-five percent (25%) of the net leasable area of such
         Building, and in the further event that Grantor shall fail to
         satisfy any of the conditions set forth in clauses (2), (3)
         and (4) of the first sentence of this Subsection 1.07(b) with
         respect to such damage or destruction, then Grantee may apply
         the Net Insurance Proceeds to the reduction of the Secured
         Indebtedness in such order as Grantee may determine, but (in
         the absence of an Event of Default) Grantee shall not declare
         the entire Secured Indebtedness immediately due and payable
         solely as a result of Grantor's failure to satisfy such
         conditions or as a result of Grantor's failure to effect the
         Restoration of such Building if Grantee applies the Net
         Insurance Proceeds to the reduction of the Secured
         Indebtedness. If Grantee shall elect, under such
         circumstances, to apply the Net Insurance Proceeds to the
         reduction of the Secured Indebtedness, Grantee shall give
         written notice of such election (the "Special Election
         Notice') to Grantor, and Grantee shall then have a special
         right (i.e., in addition to its general rights under Article 2
         of the Loan Agreement) to obtain a Release of the parcel or
         parcels on which the damaged or destroyed portions of the
         Improvements are situated if the following conditions are met:

               (i) Grantor delivers to Grantee, no later than ten (10) business
days after the effective date of the Special Election Notice, a Request for
Release in accordance with the terms and conditions set forth in the Loan
Agreement, requesting the release of the parcel or parcels on which the damaged
or destroyed portions of the Improvements are situated;

               (ii) No later than ninety (90) days after the Request for Release
is submitted to Grantee, Grantor satisfies all of the conditions and
requirements for such Release under the Loan Agreement except for the condition
set forth in Section 2. l (a) of the Loan Agreement, which requirement is hereby
waived by Grantee with respect to such Release; and

               (iii) The Release Amount is paid to Grantee on the Release Date
(it being agreed by Grantee that the Net Insurance Proceeds arising out of the
damage or destruction to the Improvements on the parcel or parcels being
Released may be applied towards the Release Amount)."

          (b) Any party hereto may change the address to which notices shall be
directed under this Section 6.1 by giving ten (10) days' prior written notice of
such change to the other party.

     Section 6.2 Waivers. No failure or delay by Lender in exercising any right
of Lender hereunder shall operate as a waiver of such right. Lender expressly
reserves the right to require strict compliance with the terms of this Agreement
in connection with any Request for Release or Request for Transfer. In the event
Lender decides to approve a Request for Release or Request for Transfer at a
time when Borrower is not in strict compliance with the terms of this Agreement,
such decision by Lender shall not be deemed to constitute an undertaking by
Lender to approve any further Request for Release or Request for Transfer or
preclude Lender from exercising any rights available to Lender under the Loan
Documents or at law or equity. Any waiver or indulgence granted by Lender shall
not constitute a modification of this Agreement, except to the extent expressly
provided in such waiver or indulgence, or constitute a course of dealing by
Lender at variance with the terms of this Agreement such as to require further
notice by Lender of Lender's intent to require strict adherence to the terms of
this Agreement in the future. Any such actions shall not in any way affect the
ability of Lender, in Lender's discretion, to exercise any rights available to
Lender under this Agreement or under any of the other Loan Documents.

     Section 6.3 Assignment. Borrower may not assign or transfer any of its
rights or obligations hereunder without the prior written consent of Lender,
except to a Beacon Affiliate to whom all of the Property is transferred in
accordance with Section 3.03(a) of the Security Deed.

     Section 6.4 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

     Section 6.5 Governing Law. This Agreement shall be construed in accordance
with and governed by the laws of the State of Georgia.

     Section 6.6 Severability. If any provision of this Agreement should be held
unenforceable or void, then such provision shall be deemed separable from the
remaining provisions and shall in no way affect the validity of this Agreement,
except that if such provision relates to the payment of any monetary sum, then,
Lender may, at its option declare the Secured Indebtedness immediately due and
payable.

     Section 6.7 Headings. Headings used in this Agreement are for convenience
only and shall not be used in connection with the interpretation of any

agreements, understandings, and conversations relating to the subject matter
hereof and thereof.

     Section 6.9 Amendment and Waiver. Neither this Agreement nor any term
hereof may be amended orally, nor may any provision hereof be waived orally but
only by an instrument in writing signed by Lender and Borrower.

     Section 6.10 Other Relationships. No relationship created hereunder or

     Section 6.11 Liability of Borrower. Notwithstanding anything to the

without in any manner releasing, impairing or otherwise affecting this Agreement
or any of the other Loan Documents, or the validity hereof or thereof, or the

the liability of Borrower and the general partners of Borrower, if any, with
respect to this Agreement and the other Loan Documents shall be limited to and
satisfied out of the Property. Notwithstanding any of the foregoing, nothing
contained in this Section 6.11 shall be deemed to prejudice the rights of Lender

any, for fraud, willful misrepresentation or willful waste committed by
Borrower, its general partner(s) or any of their officers or employees; and/or
(ii) recover any Condemnation Proceeds or Insurance Proceeds or other similar
funds or payments attributable to the Property, which may have been misapplied
by Borrower or which, under the terms of the Loan Documents, should have been

or other similar sums paid to or held by Borrower or any Other entity or person
on behalf of Borrower in connection with the Property; and/or (iv) recover the

of default (provided that with respect to a default under Section 2.01(b), (d)
or (e) of the Security Deed, notice of such default shall have been given to
Borrower), which have not been applied to pay any portion of the indebtedness
evidenced by the Note, operating and maintenance expenses of the Property,
Premiums, Impositions, deposits into a reserve for replacement or other sums
required by the Loan Documents, provided, however, that the personal liability
of Borrower with respect to such Rents and Profits under this clause (iv) shall
be eliminated with respect to such default upon the curing of such default
within any applicable grace period under the Loan Documents or upon the curing
of such default after the expiration of such grace period if Lender elects to
accept such cure (it being acknowledged by Borrower that Lender has no
obligation to accept any such cure after the expiration of a grace period);
and/or (v) recover damages against Borrower and/or the general partners of
Borrower, if any, arising from, or in connection with, the covenants,
obligations, liabilities, warranties and representations contained in Section
3.08 of the Security Deed and/or the terms, covenants and provisions of the
Unsecured Indemnity Agreement; and/or (vi) except to the extent Lender actually
received proceeds therefor under its lender's title policy, recover from
Borrower and/or the general partners of Borrower, if any, the entire

indebtedness secured by the Loan Documents, in the event of any judicial
determination that the lien of the Security Deed is invalid (provided that the
personal liability of Borrower and its general partner(s) under this clause (vi)
shall not exceed the value of the Property as of the Maturity Date or (if
earlier) the date of acceleration); and/or (vii) recover from Borrower and/or
the general partners of Borrower, if any, all amounts due and payable pursuant

Borrower and/or the general partners of Borrower, if any, arising from a breach

recover Rents or Profits under this clause (ix) accruing during the period six
(6) months prior to Lender's giving notice of acceleration of the maturity of
the Loan through the date Lender takes possession of or title to the Property,
to the extent such Rents or Profits are diverted by Borrower from payment of the
following: the indebtedness evidenced by the Note, operating and maintenance
expenses of the Property, Premiums, Impositions, deposits into a reserve for
replacement or other sums required by the Loan Documents, to the extent any of
the foregoing are due and payable at the time such Rents or Profits were
diverted. Borrower and/or the general partners of Borrower, if any, shall be
personally liable for Borrower's obligations arising in connection with the
matters set forth in the foregoing clauses (i) to (ix) inclusive.

     Section 6.12 Mezzanine Financing. Borrower hereby represents and warrants
that any and all loans secured by the Property (including but not limited to
so-called "mezzanine financing" or "bridge loans") heretofore obtained by
Borrower to finance its acquisition of the Property have been paid in full and

terms and conditions of Section 3.03(a) of the Security Deed.

and shall not constitute a release of any of Lender's obligations under that
