                  specifically and only to an earlier date in time; and

            (iv)  No event has occurred nor failed to occur which occurrence or
                  failure is, or with the passage of time or giving of notice
                  (or both, would constitute an Event of Default (as described

                  rights upon such occurrence or failure.

      (e)   The Borrower shall immediately become indebted to the Lender for the
            amount of each Advance when such Advance is made for or on behalf of
            the Borrower.

                  the account of the Borrower subject to and in accordance
                  with ss.ss.2.6, 2.7 and 2.8 of this Agreement and the
                  other provisions of this clause (f). Each such request
                  shall be in such manner as may from time to time be
                  acceptable to the Lender, in writing.

            (ii)  The Lender, shall issue any L/C so requested by the Borrower,
                  provided that the aggregate Stated Amount, following the
                  requested issuance thereof, would not when aggregated with all
                  outstanding L/C's and Advances exceed the lesser of (A) the
                  L/C Limit, or (B) Availability, and provided that the L/C is
                  in form satisfactory to the Lender.

            (iii) The Borrower shall execute such documentation to apply for and
                  support the issuance of a L/C as may be required by the
                  Lender.

      (g)   The Lender, without the request of the Borrower, may make an Advance
            equal to the amount which the Borrower is obligated to pay to the
            Lender or for which the Borrower or the Lender becomes obligated on
            account of, or in respect to, any L/C. Such Advance shall be made
            and even if such


                                       -3-
<PAGE>

            Advance would result in Loan Amount being exceeded. Such action on
            the part of the Lender shall not constitute a waiver of the Lender's
            rights under Section 2.4(b) above.

2.5 The Loan Account. (a) An account (the "Loan Account") shall be opened on the
books of the Lender, in which Loan Account ---------------- a record may be kept
of all Advances made by the Lender to the Borrower under or pursuant to this
Agreement and of all payments thereon.

      (b)   The Lender may also keep a record (either in the Loan Account or
            elsewhere, as the Lender may from time to time elect) of all
            interest, fees, service charges, costs, expenses, and other debits
            owed the Lender on account of the Obligations and of all credits
            against such amounts so owed.

      (c)   All credits against the Obligations shall be conditional upon final
            payment to the Lender of the items giving rise to such credits. The
            amount of any item credited against the Obligations which is charged
            back against the Lender for any reason or is not so paid shall be an
            Obligation and shall be added to the Loan Account, whether or not
            the item so charged back or not so paid is returned.

      (d)   Except as otherwise provided herein, all fees, service charges,
            costs, and expenses for which the Borrower is obligated hereunder
            are payable thirty (30) days after the invoice date. The Lender,
            without the request of the Borrower, may make an Advance of any
            interest, fee, service charge, or other payment to which the Lender
            is entitled from the Borrower pursuant hereto and may charge the
            same to the Loan Account notwithstanding that such amount so
            advanced may result in Availability's being exceeded. Such action on
            the part of the Lender shall not constitute a waiver of the Lender's
            rights under Section 2.4(b), above. Any amount which is added to the
            principal balance of the Loan Account as provided in this subsection
            shall bear interest at the interest rate applicable from time to
            time to the unpaid principal balance of the Loan Account.

      (e)   Any statement rendered by the Lender to the Borrower concerning the
            Obligations shall be considered correct and accepted by the Borrower
            and shall be conclusively binding upon the Borrower unless the
            Borrower provides the Lender with written objection thereto within
            thirty (30) days from the mailing of such statement, which written
            objection shall indicate, with particularity, the reason for such
            objection. The Loan Account and the Lender's books and records
            concerning the loan arrangement contemplated herein and the
            Obligations shall be prima facie evidence of the items described
            therein.


                                       -4-

2.6 Establishment of Letter of Credits. (a) Upon the written request of the
Borrower, the Lender agrees to cause the issuance of L/C's on behalf of a
Borrower as provided herein. The Borrower may request issuance of L/C's in such
manner as may from time to time be reasonably acceptable to the Lender. The
Borrower shall execute and deliver to the Lender such further documents and
instruments in connection with any L/C, as the Lender, in accordance with the
Lender's then customary practices with respect to similar facilities, may
reasonably request including, without limitation, the Lender's standard letter
of credit agreements (the "L/C Agreement"). In the event of any inconsistency
between the terms of the L/C Agreement and this Agreement the terms and
conditions of the L/C Agreement shall control.

            (b)   No L/C shall have an expiry date which is later than thirty
                  (30) days prior to the Maturity Date.

2.7 Effect of Honor of L/C's . The Borrower shall reimburse the Lender for the
amount of any honored L/C. Any such honoring which is not so reimbursed on the
Business Day when so honored shall constitute an Advance.

2.8. Additional Provisions Relating to L/C's. (a) The obligations of the
Borrower with respect to L/C's shall be absolute and unconditional. The
obligations of the Borrower with respect to L/C's shall rank pari passu with the
obligations of the Borrower to repay all other Obligations. The Lender's rights,
powers, privileges and immunities specified in or arising under this Agreement
are in addition to any hereafter created or arising, whether by statute or rule
of law or contract.

obligations to make Advances hereunder to be terminated, whereupon the same
shall terminate and the Lender shall be relieved of all obligations to make
Advances to the Borrower, and/or declare all unpaid principal of and accrued
interest on the Note, together with all other amounts owing under the Loan

immediately due and payable, anything in the Loan Documents to the contrary
notwithstanding, without presentment, protest, demand or other notice of any
kind, all of which are hereby expressly waived by the Borrower and, to the
extent Lender holds in an account any unapplied proceeds from a Syndication
Event, Lender may immediately apply such funds in satisfaction of any unpaid
principal of and accruing interest on the Note; provided that if any one or more
of the Events of Default specified in ss.11.1 (k), ss.11.1 (l), or ss.11.1 (m),
above, shall occur with respect to any Borrower, the Lender's obligations to
make Advances hereunder automatically shall so terminate and all unpaid
principal of and accrued interest on the Note, together with all other amounts
owing under the Loan Documents, automatically shall become and be immediately so
due and payable, without any declaration or other act on the part of the Lender.

11.3 Other Remedies. If any one or more of the Events of Default shall have
occurred and continued beyond any applicable grace periods, and whether or not
the Lender shall have terminated its obligations to make Advances or accelerated
the maturity of the Loan pursuant to ss.11.2 or obtained a first priority lien
on all of the properties comprising the Project, the Lender may proceed to
protect and enforce its rights and remedies under this Agreement, the Note or
any of the other Loan Documents, including, by foreclosure, exercise of set-off
or pledge rights and/or by suit in equity, action at law or other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in this Agreement and the other Loan Documents or any instrument
pursuant to which the Obligations are evidenced, including as permitted by
applicable law the obtaining of the ex parte appointment of a receiver, and, if
any amount owed to the Lender shall have become due, by declaration or
otherwise, proceed to enforce the payment thereof or any other legal or
equitable


                                      -30-
<PAGE>

right of the Lender. No remedy conferred upon the Lender or the holder of the
Note in this Agreement or in any of the other Loan Documents is intended to be
exclusive of any other remedy and each and every remedy shall be cumulative and
shall be in addition to every other remedy given hereunder or thereunder or now
or hereafter existing at law or in equity or by statute or any other provision
of law.

11.4 Distribution of Collateral Proceeds. In the event that, following the
occurrence and during the continuance of any Default or Event of Default, the
Lender receives any monies in connection with the enforcement of any the
Security Documents, or otherwise with respect to the realization upon any of the
Collateral, such monies shall be distributed for application as follows:

      (a)   First, to the payment of, or (as the case may be) the reimbursement
            of the Lender for or in respect of all reasonable costs, expenses,
            disbursements and losses which shall have been incurred or sustained
            by the Lender in connection with the collection of such monies by
            the Lender, for the exercise, protection or enforcement by the
            Lender of all or any of the rights, remedies, powers and privileges
            of the Lender under this Agreement or any of the other Loan
            Documents or in respect of the Collateral or in support of any
            provision of adequate indemnity to the Lender against any taxes or
            liens which by law shall have, or may have, priority over the rights
            of the Lender to such monies;

      (b)   Second, to all other Obligations in such order or preference as the
            Lender may determine; provided, however, that the Lender may in its
            discretion make proper allowance to take into account any
            Obligations not then due and payable;

      (c)   Third, upon payment and satisfaction in full or other provisions for
            payment in full satisfactory to the Lender of all of the
            Obligations, to the payment of any obligations required to be paid
            pursuant to ss.9-504(1)(c) of the Uniform Commercial Code of the
            Commonwealth of Massachusetts; and

      (d)   Fourth, the excess, if any, shall be returned to the Borrower or to
            such other Persons as are entitled thereto.

11.5 Power of Attorney. For the purposes of carrying out the provisions and
exercising the rights, remedies, powers and privileges granted by or referred to
in this Article, after the occurrence of an Event of Default and during the
continuation thereof the Borrower hereby irrevocably constitutes and appoints
the Lender its true and lawful attorney-in-fact, with full power of
substitution, to execute, acknowledge and deliver any instruments and do and
perform any acts which are referred to in this Article, in the name and on

respect to the Note.

14. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the
Lender from and against any and all claims, actions and suits, whether
groundless or otherwise, and from and against any and all liabilities, losses,
damages and expenses of every nature and character arising out of this Agreement
or any of the other Loan Documents or the transactions contemplated hereby and
thereby including, without limitation, (a) any brokerage, leasing, finders or
similar fees, (b) any disbursement of the proceeds of any of the Advances, (c)
any condition of the properties comprising the Project whether related to the
quality of construction or otherwise, (d) any actual or proposed use by the
Borrower of the proceeds of any of the Advances, (e) any actual or alleged

entitled to select its own counsel and, in addition to the foregoing indemnity,
the Borrower agrees to pay within thirty (30) days the reasonable fees and
expenses of such counsel. The obligations of the Borrower under this Section
shall survive the repayment of the Loan and shall continue in full force and
effect so long as the possibility of such claim, action or suit exists. If, and
to the extent that the obligations of the Borrower under this Section are
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment in satisfaction of such obligations which is
permissible under applicable law.

15. LIABILITY OF THE LENDER. The liability of the Lender to the Borrower for any
breach of the terms of this Agreement by the Lender shall not exceed a sum equal
to the amount which the Lender shall be determined to have failed to advance in
consequence of a breach by the Lender of its obligations under this Agreement,
together with interest thereon at the rate payable by the Borrower under the
terms of the Note for Advances which the Borrower is to receive hereunder,
computed from the date when the Advance should have been made by the Lender to
the date when the Advance is, in fact,


                                      -33-
<PAGE>

made by the Lender, and, upon the making of any such payment by the Lender to
the Borrower, the same shall be treated as an Advance under this Agreement, in
the same fashion as any other Advance under the terms of this Agreement. In no
event shall the Lender be liable to the Borrower, or anyone claiming by, under
or through the Borrower, for any special, exemplary, punitive or consequential
damages, whatever the nature of the breach of the terms of this Agreement by the
Lender, such damages and claims therefor being expressly WAIVED by the Borrower.

      Notwithstanding the foregoing, Borrower agrees that no action shall be
commenced by Borrower for any claim of any kind against the Lender under or in
connection with this Agreement unless written notice specifically setting forth
the claim of Borrower shall have been given to the Lender within ninety (90)
days after the occurrence of the event which Borrower alleges gives rise to such
claims, and failure to give such notice shall constitute a WAIVER of any such
claim.

16. RIGHTS OF THIRD PARTIES. All conditions to the performance of the
obligations of the Lender under this Agreement, including the obligation to make
Advances, are imposed solely and exclusively for the benefit of the Lender and
no other Person shall have standing to require satisfaction of such conditions
in accordance with their terms or be entitled to assume that the Lender will
refuse to make Advances in the absence of strict compliance with any or all
thereof and no other Person shall, under any circumstances, be deemed to be a
beneficiary of such conditions, any and all of which may be freely waived in
whole or in part by the Lender at any time if in its sole discretion it deems it
desirable to do so.

17. SURVIVAL OF COVENANTS, ETC. All covenants, agreements, representations and
warranties made herein, in the Note, in any of the other Loan Documents or in
any documents or other papers delivered by or on behalf of the Borrower pursuant
hereto and thereto shall be deemed to have been relied upon by the Lender,
notwithstanding any investigation heretofore or hereafter made by it, and shall
survive the making by the Lender of the Advances, as herein contemplated, and
shall continue in full force and effect either (i) so long as any amount due
under this Agreement or the Note or any of the other Loan Documents remains
outstanding or the Lender has any obligation to make any Advances or (ii) for
such longer period as may be provided for herein or in any other Loan Document.
All statements contained in any certificate or other paper delivered to the
Lender at any time by or on behalf of any Person or any Subsidiary thereof
pursuant hereto or in connection with the transactions contemplated hereby shall
constitute representations and warranties by such Person.

18. ASSIGNMENT AND PARTICIPATION.

18.1 Conditions to Assignment by Lender. Except as provided herein, the Lender
may assign to one or more banks or other entities (the "Banks") its interests,

assign up to fifty (50%) percent of its interests, rights, and obligation under
this Agreement, (ii) any such assignee


                                      -34-
<PAGE>

shall be a financial institution with a net worth of not less than $100,000,000;
and (iii) Lender shall provide the Borrower with at least thirty (30) days'
prior written notice of such intended assignment. From and after the effective
date of any such assignment, (i) the assignee thereunder shall be deemed to be a
party hereto and, to the extent agreed to by the Lender, have the rights and
obligations of a Lender hereunder, and (ii) the Lender shall, to the extent of
its interest assigned as provided herein, be released from its obligations under
this Agreement.

18.2 New Notes, Agreement. Upon any such assignment by the Lender, the Borrower,
at its own expense, shall execute and deliver to the Lender (a) in exchange for
the Note, a new Note (or Notes) to the order of each such assignee in an amount
equal to the amount assumed by such assignee and, if the Lender has retained
some portion of its obligations hereunder, a new Note to the order of the Lender
in an amount equal to the amount retained by it hereunder and (b) an amendment
to this Agreement and any other Loan Documents, as may be reasonably requested
by the Lender, to evidence the assignment, provide for the rights and interest
of the assignee, and establish the rights, responsibilities and obligations of
the Lender as agent for itself and any such assignee. Such new Note (or Notes)
shall be provided as replacements for the surrendered Note (or Notes), shall be
in an aggregate principal amount equal to the aggregate principal amount of the
surrendered Note (or Notes), shall be dated the effective date of such
assignment and shall otherwise be in substantially the form of the assigned Note
(or Notes). Within five (5) days of issuance of any new Notes pursuant to this
ss.18.2, the Borrower shall deliver an opinion of counsel, addressed to the
Lender and the Agent (if any), relating to the due authorization, execution and
delivery of such new Notes and the legality, validity and binding effect
thereof, in form and substance satisfactory to the Lender. The surrendered Note
(or Notes) shall be canceled and returned to the Borrower.

18.3 Participations. The Lender (and any Bank) may sell participations to one or
more banks or other entities in all or a portion of the Lender's (or Bank's)
rights and obligations under this Agreement and the other Loan Documents;
provided that (a) any such sale of participations shall not affect the rights
and duties of the Lender (or Bank) hereunder to the Borrower and (b) the only
rights granted to the participant pursuant to such participation arrangements
with respect to waivers, amendments or modifications of the Loan Documents shall
be the right to approve waivers, amendments or modifications that would reduce
the principal of or the interest rate on the Loan, extend the term or increase
the amount of the Loan or extend any regularly scheduled payment date for
principal or interest.

18.4 Pledge by the Lender. The Lender may at any time pledge all or any portion
of its interest and rights under this Agreement (including all or any portion of
the Note) to any of the twelve Federal Reserve Banks organized under ss.4 of the
Federal Reserve Act, 12 U.S.C. ss.341. No such pledge or the enforcement thereof
shall release the Lender from its obligations hereunder or under any of the
other Loan Documents.


                                      -35-
<PAGE>

18.5 No Assignment by the Borrower. The Borrower shall not assign or transfer
any of its rights or obligations under any of the Loan Documents without the
prior approval of the Lender.

19. RELATIONSHIP. The relationship between the Lender and the Borrower is solely
that of a lender and borrower, and nothing contained herein or in any of the
other Loan Documents shall in any manner be construed as making the parties
hereto partners, joint venturers or any other relationship other than lender and
borrower.

Lender for Borrower's benefit, which payment or proceeds or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, receiver or any other Person under any
bankruptcy law, state or federal law, the obligations or part thereof intended
to be satisfied shall be revived and continue in full force and effect, as if
such payment or proceeds had not been received by Lender.

      (a)   A reference to any Loan Document, agreement, budget, document or
            schedule shall include such agreement, budget, document or schedule

            material facts necessary in order to determine whether approval
            should be granted.

      (h)   Reference to a particular "ss." refers to that section of this
            Agreement unless otherwise indicated.

25. HEADINGS. The captions in this Agreement are for convenience of reference
only and shall not define or limit the provisions hereof.

26. COUNTERPARTS. This Agreement and any amendment hereof may be executed in

connection herewith or therewith express the entire understanding of the parties
with respect to the transactions contemplated hereby. Neither this Agreement nor
any term hereof may be changed, waived, discharged or terminated, except as
provided inss.28.

28. CONSENTS, AMENDMENTS, WAIVERS, ETC. Except as otherwise expressly set forth
in any particular provision of this Agreement, any consent or approval required
or permitted by this Agreement to be given by the Lender may be given, and any
term of this Agreement or of any other instrument related hereto or mentioned
herein may be amended, and the performance or observance by the Borrower of any
terms of this Agreement or such other instrument or the continuance of any
Default or Event of Default may be waived (either generally or in a particular
instance and either retroactively or prospectively) with, but only with, the
written consent of the Lender. No waiver shall extend to or affect any
obligation not expressly waived or impair any right consequent thereon. No
course of dealing or delay or omission on the part of the Lender in exercising
any right shall operate as a waiver thereof or otherwise be prejudicial thereto.
No Advance made by the Lender hereunder during the continuance of any Default or
Event of Default shall constitute a waiver thereof. No notice to or demand upon
the Borrower shall entitle the Borrower to other or further notice or demand in
similar or other circumstances. Any amendment to this Agreement or any other
Loan Document shall be made in writing and signed by the Borrower and the
Lender.

covenant, agreement and obligation of the Borrower under this Agreement and the

clause or provision hereof shall be held invalid or unenforceable in whole or in
part in any jurisdiction, then such invalidity or unenforceability shall affect
only such clause or provision, or part thereof, in such jurisdiction, and shall
not in any manner affect such clause or provision in any other jurisdiction, or
any other clause or provision of this Agreement in any jurisdiction.

31. LIMITED RECOURSE. No deficiency will be sought or judgment for money damages
will be entered against the general partners (the "General Partners") or limited
partners of the Borrower (collectively, the "Partners") with respect to any
deficiency remaining after foreclosure of any Security Deed and the Partners
shall not be personally liable in any action with respect to any deficiency
remaining after any such foreclosure or to collect any amount payable under this
Agreement, the Note and the other Loan Documents.

      Notwithstanding the foregoing, however, nothing contained in this Section
31 shall in any way whatsoever release, affect, impair or derogate from the
indebtedness evidenced by this Agreement and other Loan Documents, or the
liabilities and obligations of the Borrower under the Loan Documents or in
connection therewith, or restrict, impair or preclude the exercise of any of the
rights and remedies of the Lender under the Loan Documents, or otherwise
available at law or in equity, including, without limitation, any action to
foreclose a Security Deed or Deeds, actions against the Borrower that do not
seek to impose personal liability on the Partners, or the exercise of the rights
and remedies of Lender under this Agreement or any other Loan Document.

      Further, it is expressly understood and agreed that the aforesaid
limitation on liability shall in no way release or restrict the liability of the
General Partners to the Lender under any separate guarantees or indemnities
provided in connection with the Loan or for all amounts arising out of or
relating to the following (provided however, that in no event shall any of the
general partners or limited partners of Franklin Street Partners Limited
Partnership have any liability whatsoever to the Lender):

            proceeds of the sale or transfer of any portion of any property
            comprising the Project, or (c) proceeds from any Syndication Event;

counterclaims.
