ss.2. REVOLVING CREDIT FACILITY.

     ss.2.1. Commitment to Lend; Limitation on Total Commitment. Subject to the
provisions of ss.2.5 and the other terms and conditions set forth in this
Agreement, each of the Lenders severally agrees to lend to the Borrower and the
Borrower may borrow, repay, and reborrow from time to time between the Effective
Date and the Maturity Date upon notice by the Borrower to the Agent given and
approved by the Agent in accordance with ss.2.5, such sums as are requested by
the Borrower up to a maximum aggregate principal amount of Outstanding
Obligations (after giving effect to all amounts requested) at any one time equal
to such Lender's Commitment, provided that the sum of the Outstanding
Obligations (after giving effect to all amounts requested) shall not at any time
exceed the Maximum Credit Amount. The Loans shall be made pro rata in accordance
with each Lender's Commitment Percentage and the Lenders shall at all times
immediately adjust inter se any inconsistency between each Lender's outstanding
principal amount and each Lender's Commitment. Each request for a Loan hereunder
shall constitute a representation and warranty by the Borrower that the
conditions set forth in ss.10 or ss.11 (whichever is applicable) have been
satisfied in all material respects on the date of such request and will be
satisfied on the proposed Borrowing Date of the requested Loan, provided that
the making of such representation and warranty by Borrower shall not limit the
right of any Lender not to lend upon a determination by the Majority Lenders
that such conditions have not been satisfied.

     ss.2.2. Increase in Total Commitment.

             (a) Provided that no Default or Event of Default has occurred
and is continuing, the Borrower shall have the option to request an increase in
the Total Commitment to not more than $45,000,000 by written notice to the
Agent, provided that any such increase must become effective within the first
twelve (12) months after the Effective Date. Upon receipt of such notice, the
Agent shall consult with Arranger and shall notify the Borrower of the amount of
facility fees to be paid to any Lenders who provide an Additional Commitment in
connection with such increase in the Total Commitment. If the Borrower agrees to
pay the facility fees so determined, then the Agent shall send a notice to all
Lenders (the "Additional Commitment Request Notice") informing them of the
Borrower's request to increase the Total Commitment and of the facility fees to
be paid with respect thereto. Each Lender who desires to provide an Additional
Commitment upon such terms shall provide Agent with a written commitment letter
specifying the amount of the Additional Commitment by which it is willing to
provide prior to such deadline as may be specified in the Additional Commitment
Request Notice. If the requested increase is oversubscribed then the Agent and
the Arranger shall allocate the Commitment Increase among the Lenders who
provide such commitment letters on such basis as the Agent and the Arranger
shall determine in their sole discretion. If the Additional Commitments so
provided are not sufficient to provide the full amount of the Commitment
Increase requested by the Borrower, then the Agent may, but shall not be
obligated to, invite one or more Eligible Assignees to become a Lender and
provide an Additional Commitment. The Agent shall provide all Lenders with a
notice setting forth the amount, if any, of the Additional Commitment to be
provided by each Lender and the revised Commitment Percentages which shall be
applicable after the effective date of the Commitment Increase specified therein
(the "Commitment Increase Date").

                                      -17-

<PAGE>


             (b) On the Commitment Increase Date the outstanding principal
balance of the Loans shall be reallocated among the Lenders such that after the
Commitment Increase Date the outstanding principal amount of Loans owed to each
Lender shall be equal to such Lender's Commitment Percentage (as in effect after
the Commitment Increase Date) of the outstanding principal amount of all Loans.
On the Commitment Increase Date those Lenders whose Commitment Percentage is
increasing shall advance the funds to the Agent and the funds so advanced shall
be distributed among the Lenders whose Commitment Percentage is decreasing as
necessary to accomplish the required reallocation of the outstanding Loans. The
funds so advanced shall be Prime Rate Loans until converted to LIBOR Loans which
are allocated among all Lenders based on their Commitment Percentages. To the
extent such reallocation results in certain Lenders receiving funds which are
applied to LIBOR Loans prior to the last day of the applicable Interest Period,
then the Borrower shall pay to the Agent for the account of the affected Lenders
the LIBOR Prepayment Fee which shall be determined separately for each such
Lender in the manner set forth in ss.3.3. On the Commitment Increase Date, the
Lenders' respective interests in outstanding Letters of Credit shall also be
adjusted to reflect the revised Commitment Percentages. Upon request from any
Lender whose interest in an outstanding Letter of Credit is so increasing, the
Borrower will pay additional Letter of Credit fees for the amount of such
increase at the rate provided in ss.2.8(c) prorated for the period from the
Commitment Increase Date until the expiration of the applicable Letter of
Credit.

             (c) Upon the effective date of each increase in the Total
Commitment pursuant to this ss.2.2 the parties shall enter into an amendment of
this Agreement revising Schedule 1.1 and the Borrower shall execute and deliver
to the Agent new Notes for each Lender whose Commitment has changed so that the
principal amount of such Lender's Note shall equal its Commitment. The Agent
shall deliver such replacement Notes to the respective Lenders in exchange for
the Notes replaced thereby which shall be surrendered by such Lenders. Such new
Notes shall provide that they are replacements for the surrendered Notes and
that they do not constitute a novation, shall be dated as of the Commitment
Increase Date and shall otherwise be in substantially the form of the replaced
Notes. Within five (5) days of issuance of any new Notes pursuant to this
ss.2.2(d), the Borrower shall deliver an opinion of counsel, addressed to the
Lenders and the Agent, relating to the due authorization, execution and delivery
of such new Notes and the enforceability thereof, in form and substance
substantially similar to the opinion delivered in connection with the first
disbursement under this Agreement. The surrendered Notes shall be canceled and
returned to the Borrower.

     ss.2.3. The Notes. The Loans shall be evidenced by separate promissory
notes of the Borrower in substantially the form of Exhibit A hereto (each a
"Note"), and completed with appropriate insertions. One or more Notes shall be
payable to the order of each Lender in an aggregate principal amount equal to
such Lender's Commitment. The Borrower irrevocably authorizes each Lender to
make or cause to be made, at or about the time of the Borrowing Date of any Loan
or at the time of receipt of any payment of principal on such Lender's Note, an
appropriate notation on such Lender's Record reflecting the making of such Loan
or (as the case may be) the receipt of such payment. The outstanding amount of
the Loans set forth on such Lender's Record shall (absent manifest error) be
prima facie evidence of the principal amount thereof owing and unpaid to such
Lender, but the failure to record, or any error in so recording, any such amount
on the Record shall not limit or otherwise affect the obligations of the
Borrower hereunder or under any Note to make payments of principal of or
interest on any Note when due. Upon receipt of an affidavit of an officer of any

                                      -18-

<PAGE>


Lender as to the loss, theft, destruction or mutilation of its Note or any other
security document which is not of public record, and, in the case of any such
loss, theft, destruction or mutilation, upon cancellation of such Note or other
security document, Borrower will issue, in lieu thereof, a replacement Note or
other security document in the same principal amount thereof and otherwise of
like tenor.

     ss.2.4. Interest on Loans.

             (a) Each Prime Rate Loan shall bear interest for the period
commencing with the Borrowing Date thereof and ending on the last day of the
Interest Period with respect thereto at the rate equal to 0.75% per annum above
the Prime Rate.

             (b) Each LIBOR Loan shall bear interest for the period commencing
with the Borrowing Date thereof and ending on the last day of the Interest
Period with respect thereto at the rate equal to the 2.75% per annum above LIBOR
determined for such Interest Period.

             (c) The Borrower unconditionally promises to pay interest on each
Loan in arrears on each Interest Payment Date with respect thereto.

     ss.2.5. Requests for Loans. The Borrower shall give to the Agent written
notice in the form of Exhibit B hereto of each Loan requested hereunder (a "Loan
Request") no less than (a) one (1) Business Day prior to the proposed Borrowing
Date of any Prime Rate Loan and (b) three (3) LIBOR Business Days prior to the
proposed Borrowing Date of any LIBOR Loan. Each such notice shall specify (i)
the principal amount of the Loan requested, (ii) the proposed Borrowing Date of
such Loan, (iii) the Interest Period for such Loan, and (iv) the Type of such
Loan, and shall be accompanied by a Compliance Certificate based on the most
recent certificate deliver pursuant to ss. 7.4 (d) with updated calculations
evidencing compliance with the covenants contained in ss.9.1 through ss.9.3
hereof after giving effect to such requested Loan. Within one (1) Business Day
after receipt of a Loan Request, the Agent shall provide to each of the Lenders
by facsimile a copy of such Loan Request and accompanying Compliance Certificate
and each Lender shall, within 24 hours thereafter, notify the Agent if it
believes that any of the conditions contained in ss.11 of this Agreement has not
been met or waived. If such a notice is given the Majority Lenders shall
promptly determine whether all of the conditions contained in ss.11 of this
Agreement have been met or waived. If no such notice is given by any Lender or
if following such notice the Majority Lenders determine that the conditions
contained in ss.11 have been met or waived, each of the Lenders shall be
obligated to fund its Commitment Percentage of the requested Loans. Each such
Loan Request shall be irrevocable and binding on the Borrower and the Borrower
shall be obligated to accept the Loan requested from the Lenders on the proposed
Borrowing Date. Each Loan Request shall be in a minimum aggregate amount of
$5,000,000 or an integral multiple of $1,000,000 in excess thereof.

     ss.2.6. Conversion Options.

             (a) The Borrower may elect from time to time to convert any
outstanding Loan to a Loan of another Type, provided that (i) with respect to
any such conversion of a LIBOR Loan to a Prime Rate Loan, the Borrower shall
give the Agent at least three (3) Business Days, prior written notice of such
election; (ii) with respect to any such conversion of a LIBOR Loan into a Prime

                                      -19-

<PAGE>


Rate Loan, such conversion shall only be made on the last day of the Interest
Period with respect thereto; (iii) subject to the further proviso at the end of
this section and subject to ss.2.6(b) and ss.2.6(d) hereof with respect to any
such conversion of a Prime Rate Loan to a LIBOR Loan, the Borrower shall give
the Agent at least three (3) LIBOR Business Days, prior written notice of such
election and (iv) no Loan may be converted into a LIBOR Loan when any Default or
Event of Default has occurred and is continuing. On the date on which such
conversion is being made, each Lender shall take such action as is necessary to
transfer its Commitment Percentage of such Loans to its Domestic Lending Office
or its LIBOR Lending Office, as the case may be. All or any part of outstanding
Loans of any Type may be converted as provided herein, provided further that
each Conversion Request relating to the conversion of a Prime Rate Loan to a
LIBOR Loan shall be for an amount equal to $5,000,000 or an integral multiple of
$1,000,000 in excess thereof and shall be irrevocable by the Borrower.

             (b) Any Loans of any Type may be continued as such upon the
expiration of an Interest Period with respect thereto by compliance by the
Borrower with the notice provisions contained in ss.2.6 (a) ; provided that no
LIBOR Loan may be continued as such when any Default or Event of Default has
occurred and is continuing but shall be automatically converted to a Prime Rate
Loan on the last day of the first Interest Period relating thereto ending during
the continuance of any Default or Event of Default of which the officers of the
Agent active upon the Borrower's account have actual knowledge.

             (c) In the event that the Borrower does not notify the Agent of its
election hereunder with respect to any Loan, such Loan shall be automatically
converted to a Prime Rate Loan at the end of the applicable Interest Period.

             (d) The Borrower may not request a LIBOR Loan pursuant to ss.2.5,
elect to convert a Prime Rate Loan to a LIBOR Loan pursuant to ss.2.6(a) or
elect to continue a LIBOR Loan pursuant to ss.2.6(b) if, after giving effect
thereto, there would be greater than three (3) LIBOR Loans outstanding. Any Loan
Request for a LIBOR Loan that would create greater than three (3) LIBOR Loans
outstanding shall be deemed to be a Loan Request for a Prime Rate Loan.

     ss.2.7. Funds for Loans.

             (a) Subject to ss.2.5 and other provisions of this Agreement, not
later than 11:00 a.m. (Boston time) on the proposed Borrowing Date of any Loans,
each of the Lenders will make available to the Agent, at the Agent's Head
Office, in immediately available funds, the amount of such Lender's Commitment
Percentage of the amount of the requested Loans. Upon receipt from each Lender
of such amount, and upon receipt of the documents required by ss.ss.10 or 11
(whichever is applicable) and the satisfaction of the other conditions set forth
therein, to the extent applicable, the Agent will make available to the Borrower
the aggregate amount of such Loans made available to the Agent by the Lenders.
The failure or refusal of any Lender to make available to the Agent at the
aforesaid time and place on any Borrowing Date the amount of its Commitment
Percentage of the requested Loans shall not relieve any other Lender from its
several obligation hereunder to make available to the Agent the amount of such
other Lender's Commitment Percentage of any requested Loans but shall not
obligate any other Lender or Agent to fund more than its Commitment Percentage
of the requested Loans or to increase its Commitment Percentage.

                                      -20-

<PAGE>


             (b) The Agent may, unless notified to the contrary by any Lender
prior to a Borrowing Date, assume that such Lender has made available to the
Agent on such Borrowing Date the amount of such Lender's Commitment Percentage
of the Loans to be made on such Borrowing Date, and the Agent may (but it shall
not be required to), in reliance upon such assumption, make available to the
Borrower a corresponding amount. If any Lender makes available to the Agent such
amount on a date after such Borrowing Date, such Lender shall pay to the Agent
on demand an amount equal to the product of (i) the average computed for the
period referred to in clause (iii) below, of the weighted average interest rate
paid by the Agent for federal funds acquired by the Agent during each day
included in such period, times (ii) the amount of such Lender's Commitment
Percentage of such Loans, times (iii) a fraction, the numerator of which is the
number of days or portion thereof that elapsed from and including such Borrowing
Date to the date on which the amount of such Lender's Commitment Percentage of
such Loans shall become immediately available to the Agent, and the denominator
of which is 365. A statement of the Agent submitted to such Lender with respect
to any amounts owing under this paragraph shall be prima facie evidence of the
amount due and owing to the Agent by such Lender.

     ss.2.8. Letters of Credit.

             (a) Up to $5,000,000 of the Commitments may be used by Borrower for
the issuance of Letters of Credit by the Agent for the account of the Borrower
subject to the terms and conditions set forth herein. Each Letter of Credit
shall be denominated in Dollars and shall be a standby letter of credit issued
to support the obligations of Borrower in connection with any purposes for which
the proceeds of the Loans may be used pursuant to ss.7.11. Each Letter of Credit
shall have an initial term of not more than one (1) year, and shall expire no
later than five (5) Business Days prior to the Maturity Date. Although the Agent
shall be the issuing bank of the Letter of Credit, each Lender hereby accepts
for its own account and risk an undivided interest equal to its Commitment
Percentage in the Agent's obligations and rights under each Letter of Credit
issued hereunder. Each Lender unconditionally and irrevocably agrees with the
Agent that, if a draft is paid under any Letter of Credit, such Lender shall
promptly pay to the Agent an amount equal to such Lender's Commitment Percentage
of the amount of such draft or any part thereof. Upon the issuance of each
Letter of Credit hereunder, there shall be reserved from each Lender's
Commitment an amount equal to such Lender's Commitment Percentage of the stated
amount of the Letter of Credit. Such reserved amounts shall remain in place and
shall be unavailable for borrowing under ss.2.1 until the date that the Letter
of Credit expires, is fully drawn or is terminated.

             (b) The Borrower shall give to the Agent a written notice in the
form of Exhibit E hereto of each Letter of Credit requested hereunder (a "Letter
of Credit Request") no less than five (5) Business Days prior to the proposed
issuance date of the requested Letter of Credit. Each Letter of Credit Request
shall specify (i) the name and address of the beneficiary of the requested
Letter of Credit, (ii) the stated amount of the requested Letter of Credit,
(iii) the proposed issuance date and expiration date of the requested Letter of
Credit, (iv) the proposed form of the requested Letter of Credit, and (v) the
permitted purpose for which the Letter of Credit will be used, and shall be

                                      -21-

<PAGE>


accompanied by a Compliance Certificate based on the most recent certificate
deliver pursuant to ss. 7.4 (d) with updated calculations evidencing compliance
with the covenants contained in ss.9.1 through ss.9.3 hereof after including in
the Outstanding Obligations and Total Liabilities the stated amount of the
requested Letter of Credit. The Agent may also require that the Borrower
complete its standard letter of credit application in the form, as such standard
form may be revised from time to time, and submit the same together with the
Letter of Credit Request. Within two (2) Business Days after receipt of a Letter
of Credit Request, the Agent shall provide to each of the Lenders by facsimile a
copy of such Letter of Credit Request and accompanying Compliance Certificate
and each Lender shall, within 24 hours thereafter, notify the Agent if it
believes that any of the conditions contained in ss.11 of this Agreement has not
been met or waived such that a Loan in an amount equal to the stated amount of
the requested Letter of Credit could be made on the proposed issuance date of
such Letter of Credit. If such a notice is given the Majority Lenders shall
promptly determine whether all of the conditions contained in ss.11 of this
Agreement have been met or waived. If no such notice is given by any Lender or
if following such notice the Majority Lenders determine that the conditions
contained in ss.11 have been met or waived, and if the Agent determines, in its
discretion, that it is willing to issue the requested Letter of Credit, and that
it is satisfied with the proposed form thereof, the Letter of Credit shall be
issued by the Agent and each of the Lenders shall then be obligated to the Agent
with respect to its Commitment Percentage of the Letter of Credit as provided
above in ss.2.8(a).

             (c) On or before the issuance date of any requested Letters of
Credit, the Borrower shall pay to the Agent for its own account an issuance fee
equal to one-eighth percent (.125%) of the stated amount of the Letter of
Credit. On or before the date of any renewal or extension of a Letter of Credit,
the Borrower shall pay to the Agent for its own account a renewal fee equal to
five-hundredths percent (.05%) of the stated amount of the Letter of Credit. The
Borrower shall pay to the Agent for the account of the Lenders a Letter of
Credit fee equal to 2.75% per annum of the stated amount of the Letter of
Credit, which Letter of Credit fee shall be due and payable on the issuance date
of the Letter of Credit and on the date of each renewal or extension thereof,
and shall be prorated for any partial year based on a 360-day year and paid for
the actual number of days between the issuance date and the expiration date of
such Letter of Credit. Promptly after its receipt thereof the Agent shall
distribute such Letter of Credit fee to the Lenders pro-rata in accordance with
their respective Commitment Percentages. Such fees shall be nonrefundable and
shall not be further prorated in the event that the Letter of Credit terminates
prior to its scheduled expiration date. The Borrower also agrees to reimburse
the Agent for all reasonable fees, costs, expenses and disbursements of the
Agent in issuing, effecting payment under, amending or otherwise administering
any Letter of Credit.

             (d) Promptly after each Drawing Date the Agent shall notify the
Lenders and the Borrower of the amount of the draft paid by the Agent on such
Drawing Date. The payment of a draft under a Letter of Credit shall constitute
an advance of a Mandatory Prime Rate Loan which shall bear interest as a Prime
Rate Loan from the Drawing Date. On the Drawing Date each Lender shall make
available to the Agent in immediately available funds its Commitment Percentage
of the amount of the Mandatory Prime Rate Loan so advanced upon such payment of
a draft under the Letter of Credit. If the Agent receives such funds from any
Lender on a date after the Drawing Date, such Lender shall pay to the Agent on

                                      -22-

<PAGE>


demand an amount computed in the same manner as the amount due to the Agent from
a Lender which has made available funds for loans after the Borrowing Date
thereof pursuant to ss.2.7(b). Each Lender's obligation to fund its Commitment
Percentage of Mandatory Prime Rate Loans arising from the payment of a draft
under a Letter of Credit shall not be subject to the satisfaction of the
conditions set forth in ss.11. Within three (3) Business Days after each Drawing
Date, the Borrower shall deliver to the Agent a written explanation of the facts
and circumstances relating to such drawing and a Compliance Certificate and any
other information requested by the Agent for the purpose of allowing the Lenders
to determine whether the drawing or related events have resulted in a Default or
Event of Default. The Agent shall promptly provide copies of such explanation
and information to the Lenders. In the event that a Mandatory Prime Rate Loan
cannot be made on the date required in this paragraph, upon written demand by
the Agent, each other Lender shall purchase from the Agent a participating
interest in the unreimbursed draft paid pursuant to such Letter of Credit in an
amount equal to such other Lender's Commitment Percentage of such unreimbursed
draft. Each Lender agrees to purchase its Commitment Percentage of such
unreimbursed draft within one (1) business day after such demand therefor is
made by the Agent and on such date of purchase, an amount equal to such Lender's
Commitment Percentage of the such unreimbursed draft to be purchased by such
Lender shall be advanced to the Agent.

             (e) The Borrower's obligations under this ss.2.8 shall be absolute
and unconditional under any and all circumstances and irrespective of any
set-off, counterclaim or defense to payment which the Borrower may have or have
had against the Agent, any Lender or any beneficiary of a Letter of Credit. The
Borrower also agrees that the Agent shall not be responsible for, and the
Borrower's reimbursement obligations hereunder shall not be affected by, among
other things, (i) the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or (ii) any dispute between or among the Borrower
and any beneficiary of any Letter of Credit or any other party to which such
Letter of Credit may be transferred or (iii) any claims whatsoever of the
Borrower against any beneficiary of such Letter of Credit or any such
transferee. The Agent shall not be liable for any error, omission, interruption
or delay in transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors,
omissions, interruptions or delays caused by the Agent's gross negligence or
willful misconduct. The Borrower agrees that any action taken or omitted by the
Agent under or in connection with any Letter of Credit or the related drafts or
documents, if done in the absence of gross negligence or willful misconduct and
in accordance with the standards of care specified in the Uniform Customs and
Practices for Documentary Credits as the same may be amended from time to time,
shall be binding on the Borrower and shall not result in any liability of the
Agent to the Borrower.

             (f) In the event that any Letters of Credit are in effect at the
time of an acceleration of the maturity of the Loans pursuant to ss.12.1, the
amounts which shall thereupon become immediately due and payable by the Borrower
shall include a sum equal to the aggregate stated amount of such then effective
Letters of Credit. Such sum shall be deposited in a cash collateral account to
be opened by the Agent which shall be under the sole dominion and control of the
Agent. The Borrower hereby grants to the Agent, for the benefit of the Lenders,
as security for the Obligations a first priority security interest in such cash
collateral account and all deposits at any time therein and the proceeds thereof

                                      -23-

<PAGE>


and the Borrower shall execute and deliver such documents and take all actions
as may be required to create and maintain a valid and perfected first priority
Lien on such cash collateral account in favor of the Agent. Amounts held in such
cash collateral account shall be applied by the Agent on each Drawing Date
thereafter to pay any drafts presented pursuant to the Letters of Credit. After
all Letters of Credit have been fully drawn upon, expired or otherwise
terminated, any balance remaining in such cash collateral account shall be
applied in the same manner as Collateral proceeds under ss.12.4.

ss.3. REPAYMENT OF THE LOANS.

      ss.3.1. Maturity. The Borrower unconditionally promises to pay on the
Maturity Date, and there shall become absolutely due and payable on the Maturity
Date, all of the Loans outstanding on such date, together with any and all
accrued and unpaid interest and charges thereon.

      ss.3.2. Mandatory Repayments of Loan. If at any time the sum of the
Outstanding Obligations exceeds the Maximum Credit Amount, then the Borrower
shall immediately pay the amount of such excess to the Agent for the respective
accounts of the Lenders for application to the Loans.

      ss.3.3. Optional Repayments of Loans. The Borrower shall have the right,
at its election, to repay the outstanding amount of the Loans, as a whole or in
part, on any Business Day, without penalty or premium; provided that the full or
partial prepayment of the outstanding amount of any LIBOR Loans made pursuant to
this ss.3.3 may be made only on the last day of the Interest Period relating
thereto, except as set forth below in this ss.3.3. The Borrower shall give the
Agent no later than 10:00 a.m., Boston time, at least two (2) Business Days'
prior written notice of any prepayment pursuant to this ss.3.3 of any Prime Rate
Loans and four (4) LIBOR Business Days, notice of any proposed repayment
pursuant to this ss.3.3 of any LIBOR Loans, specifying the proposed date of
payment of Loans and the principal amount to be paid. The Agent shall promptly
notify each Lender of the principal amount of such payment to be received by
such Lender. Each such partial prepayment of the Loans shall be in an integral
multiple of $1,000,000 and, to the extent requested by the Agent, shall be
accompanied by the payment of all charges outstanding on all Loans and of
accrued interest on the principal repaid to the date of payment. The principal
payments so received shall be applied first to the principal of Prime Rate Loans
and then to the principal of LIBOR Loans. Notwithstanding anything contained
herein to the contrary, the Borrower may make a full or partial prepayment of a
LIBOR Loan on a date other than the last day of the Interest Period relating
thereto, if all optional prepayments (in whole or in part) on such Loans shall
be accompanied by, and the Borrower hereby promises to pay, a prepayment fee in
an amount determined by the Agent in the following manner:

              (a) LIBOR Prepayment Fee. Borrower acknowledges that prepayment or
acceleration of a LIBOR Loan during an Interest Period shall result in the
Lenders incurring additional costs, expenses and/or liabilities and that it is
extremely difficult and impractical to ascertain the extent of such costs,
expenses and/or liabilities. (For all purposes of this Section, any Loan not
being made as a LIBOR Loan in accordance with the Loan Request therefor, as a
result of Borrower's cancellation thereof, shall be treated as if such LIBOR
Loan had been prepaid.) Therefore, on the date a LIBOR Loan is prepaid or the

                                      -24-

<PAGE>


date all sums payable hereunder become due and payable, by acceleration or
otherwise ("Prepayment Date"), Borrower will pay to Agent, for the account of
each Lender, (in addition to all other sums then owing), an amount ("LIBOR
Prepayment Fee") determined by the Agent as follows: The current rate for United
States Treasury securities (bills on a discounted basis shall be converted to a
bond equivalent) with a maturity date closest to the end of the Interest Period
as to which prepayment is made, shall be subtracted from the interest rate
applicable to the LIBOR Loan being prepaid. If the result is zero or a negative
number, there shall be no LIBOR Prepayment Fee. If the result is a positive
number, then the resulting percentage shall be multiplied by the amount of the
prepayment of the LIBOR Loan. The resulting amount shall be divided by 360 and
multiplied by the number of days remaining in the Interest Period as to which
the prepayment is being made. The resulting amount shall be the LIBOR Prepayment
Fee.

              (b) Upon the written notice to Borrower from Agent, Borrower shall
immediately pay to Agent, for the account of the Lenders, the LIBOR Prepayment
Fee. Such written notice (which shall include calculations in reasonable detail)
shall, in the absence of manifest error, be conclusive and binding on the
parties hereto.

              (c) Borrower understands, agrees and acknowledges the following:
(i) no Lender has any obligation to purchase, sell and/or match funds in
connection with the use of the LIBOR Rate as a basis for calculating the rate of
interest on a LIBOR Loan; (ii) the LIBOR Rate is used merely as a reference in
determining such rate; and (iii) Borrower has accepted the LIBOR Rate as a
reasonable and fair basis for calculating such rate and a LIBOR Prepayment Fee.
Borrower further agrees to pay the LIBOR Prepayment Fee, if any, whether or not
a Lender elects to purchase, sell and/or match funds.

ss.4. CERTAIN GENERAL PROVISIONS.

      ss.4.1. Fees. On the Effective Date, the Borrower shall pay to FNB the
fees in the amounts specified in the Term Sheet provided by FNB to the Borrower
dated September 18, 2002. FNB shall be responsible for any fees which it may
agree to pay to other Lenders. In addition, upon each addition or substitution
of Mortgaged Properties under ss.5, Borrower shall pay Agent, for the account of
Agent only, an additional Agent's fee of $2,500.

      ss.4.2. Unused Fee. The Borrower shall pay to the Agent for the accounts
of the Lenders in accordance with their respective Commitment Percentages an
Unused Fee calculated at the rates set forth below per annum on the daily amount
by which the Total Commitment exceeds the Outstanding Obligations at the
applicable annual rate determined for each fiscal quarter as follows:

          (i) if the average Outstanding Obligations during such quarter was
     less than 50% of the Total Commitment, then the applicable Unused Fee is at
     the rate of .40% per annum for such fiscal quarter; or

          (ii) if the average Outstanding Obligations during such quarter was
     equal to or greater than 50% of the Total Commitment, then the applicable
     Unused Fee is at the rate of .20% per annum for such fiscal quarter.

                                      -25-

<PAGE>


     The Unused Fee shall be payable on the basis of the applicable annual rate
quarterly in arrears on or before the third Business Day of each calendar
quarter for the immediately preceding calendar quarter commencing on the first
such date following the date hereof, with a final payment on the Maturity Date
or any earlier date on which the Commitments shall terminate. If Borrower
exercises its option to increase the Total Commitment pursuant to ss.2.2(a), the
Unused Fee shall be computed separately for the portions of the quarter prior to
and after the Commitment Increase Date and allocated among the Lenders based on
the Commitment Percentages applicable during each portion of said quarter.

     ss.4.3. Funds for Payments.

             (a) All payments of principal, interest, closing fees, commitment
fees and any other amounts due hereunder (other than as provided in ss.2.2(b),
ss.3.1(b), ss.4.1, ss.4.5 and ss.4.6) or under any of the other Loan Documents,
and all prepayments, shall be made to the Agent, for the respective accounts of
the Lenders, at the Agent's Head Office, in each case in Dollars in immediately
available funds.

             (b) All payments by the Borrower hereunder and under any of the
other Loan Documents shall be made without setoff or counterclaim and free and
clear of and without deduction for any taxes, levies, imposts, duties, charges,
fees, deductions, withholdings, compulsory liens, restrictions or conditions of
any nature now or hereafter imposed or levied by any jurisdiction or any
political subdivision thereof or taxing or other authority therein unless the
Borrower is compelled by law to make such deduction or withholding. If any such
obligation is imposed upon the Borrower with respect to any amount payable by it
hereunder or under any of the other Loan Documents, the Borrower shall pay to
the Agent, for the account of the Lenders or (as the case may be) the Agent, on
the date on which such amount is due and payable hereunder or under such other
Loan Document, such additional amount in Dollars as shall be necessary to enable
the Lenders or the Agent to receive the same net amount which the Lenders or the
Agent would have received on such due date had no such obligation been imposed
upon the Borrower. The Borrower will deliver promptly to the Agent certificates
or other valid vouchers for all taxes or other charges deducted from or paid
with respect to payments made by the Borrower hereunder or under such other Loan
Document.

     ss.4.4. Computations. All computations of interest on the Loans and of
other fees to the extent applicable shall be made on the basis of 360-day year
and the actual number of days elapsed. Except as otherwise provided in the
definition of the term "Interest Period" with respect to LIBOR Loans, whenever a
payment hereunder or under any of the other Loan Documents becomes due on a day
that is not a Business Day, the due date for such payment shall be extended to
the next succeeding Business Day, and such extension of time shall be included
in computing interest and fees in connection with such payment. The outstanding
amount of the Loans as reflected on the Records from time to time shall (absent
manifest error) be considered correct and binding on the Borrower unless within
thirty (30) Business Days after receipt by the Agent or any of the Lenders from
Borrower of any notice by the Borrower of such outstanding amount, the Agent or
such Lender shall notify the Borrower to the contrary.

                                      -26-

<PAGE>


     ss.4.5. Additional Costs, Etc. If any present or future applicable law
(which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Lender or the Agent by any central bank or other fiscal,
monetary or other authority, whether or not having the force of law), shall:

             (a) subject any Lender or the Agent to any tax, levy, impost, duty,
charge, fee, deduction or withholding of any nature with respect to this
Agreement, the other Loan Documents, such Lender's Commitment or the Loans
(other than taxes based upon or measured by the income or profits of such Lender
or the Agent), or

             (b) materially change the basis of taxation (except for changes in
taxes on income or profits) of payments to any Lender of the principal of or the
interest on any Loans or any other amounts payable to any Lender under this
Agreement or the other Loan Documents, or

             (c) impose or increase or render applicable (other than to the
extent specifically provided for elsewhere in this Agreement) any special
deposit, reserve, assessment, liquidity, capital adequacy or other similar
requirements (whether or not having the force of law) against assets held by, or
deposits in or for the account of, or Loans by, or commitments of an office of
any Lender, or

             (d) impose on any Lender any other conditions or requirements with
respect to this Agreement, the other Loan Documents, the Loans, the Commitment,
or any class of Loans or commitments of which any of the Loans or the Commitment
forms a part;

and the result of any of the foregoing is

             (i) to increase the cost to such Lender of making, funding,
issuing, renewing, extending or maintaining any of the Loans or such Lender's
Commitment, or

             (ii) to reduce the amount of principal, interest or other amount
payable to such Lender or the Agent hereunder on account of the Commitments or
any of the Loans, or

             (iii) to require such Lender or the Agent to make any payment or to
forego any interest or other sum payable hereunder, the amount of which payment
or foregone interest or other sum is calculated by reference to the gross amount
of any sum receivable or deemed received by such Lender or the Agent from the
Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by such Lender
or (as the case may be) the Agent at any time and from time to time and as often
as the occasion therefor may arise, pay to such Lender or the Agent, to the
extent permitted by law, such additional amounts as will be sufficient to
compensate such Lender or the Agent for such additional cost, reduction, payment
or foregone interest or other sum.

                                      -27-

<PAGE>


     ss.4.6. Capital Adequacy. If any present or future law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) or the interpretation thereof by a court or governmental authority with
appropriate jurisdiction affects the amount of capital required or expected to
be maintained by banks or bank holding companies and any Lender or the Agent
determines that the amount of capital required to be maintained by it is
increased by or based upon the existence of the Loans made or deemed to be made
pursuant hereto, then such Lender or the Agent may notify the Borrower of such
fact, and the Borrower shall pay to such Lender or the Agent from time to time
on demand, as an additional fee payable hereunder, such amount as such Lender or
the Agent shall determine in good faith and certify in a notice to the Borrower
to be an amount that will adequately compensate such Lender or the Agent in
light of these circumstances for its increased costs of maintaining such
capital. Each Lender and the Agent shall allocate such cost increases among its
customers in good faith and on an equitable basis.

     ss.4.7. Certificate. A certificate setting forth any additional amounts
payable pursuant to ss.ss.4.5 or 4.6 and a brief explanation of such amounts
which are due, submitted by any Lender or the Agent to the Borrower, shall be
prima facie evidence that such amounts are due and owing.

     ss.4.8. Indemnity. In addition to the other provisions of this Agreement
regarding any such matters, the Borrower agrees to indemnify each Lender and to
hold each Lender harmless from and against any loss, cost or reasonable expense
(including loss of anticipated profits) that such Lender may sustain or incur as
a consequence of (a) a default by the Borrower in payment of the principal
amount of or any interest on any LIBOR Loans as and when due and payable,
including any such loss or expense caused by Borrower's breach or other default
and arising from interest or fees payable by such Lender to lenders of funds
obtained by it in order to maintain its LIBOR Loans, (b) a default by the
Borrower in making a borrowing or conversion after the Borrower has given (or is
deemed to have given) a Loan Request or a Conversion Request, (c) the making of
any payment of a LIBOR Loan or the making of any conversion of a LIBOR Loan to a
Prime Rate Loan on a day that is not the last day of the applicable Interest
Period with respect thereto, including interest or fees payable by such Lender
to lenders of funds obtained by it in order to maintain any such LIBOR Loan and
(d) any failure by the Borrower to prepay a LIBOR Loan on the date specified in
a prepayment notice given by the Borrower.

     ss.4.9. Default Interest and Late Charges. During any period when an Event
of Default has occurred and is continuing, or after the Maturity Date or after
judgment has been rendered on any Note, Borrower's right to select LIBOR Loans
shall cease and the unpaid principal of all Loans shall, at the option of each
Lender bear interest at a rate which is four (4) percentage points per annum
greater than that which would otherwise be applicable to Prime Rate Loans. If
the entire amount of any required principal and/or interest is not paid in full
within ten (10) days after the same is due, Borrower shall pay to the Agent a
late fee equal to five percent (5%) of the required payment.

     ss.4.10. Inability to Determine LIBOR Rate. In the event, prior to the
commencement of any Interest Period relating to any LIBOR Loan, the Agent shall
reasonably determine that adequate and reasonable methods do not exist for
ascertaining the LIBOR Rate that would otherwise determine the rate of interest

                                      -28-

<PAGE>


to be applicable to any LIBOR Loan during any Interest Period, the Agent shall
forthwith give notice of such determination (which shall be conclusive and
binding on the Borrower) to the Borrower. In such event (a) any Loan Request
with respect to LIBOR Loans shall be automatically withdrawn and shall be deemed
a request for Prime Rate Loans, (b) each LIBOR Loan will automatically, on the
last day of the then current Interest Period thereof, become a Prime Rate Loan,
and (c) the obligations of the Lenders to make LIBOR Loans shall be suspended
until the Agent reasonably determines that the circumstances giving rise to such
suspension no longer exist, whereupon the Agent shall so notify the Borrower.

     ss.4.11. Illegality. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Lender to make or maintain
LIBOR Loans, such Lender shall forthwith give notice of such circumstances to
the Borrower and thereupon (a) the Commitment of such Lender to make LIBOR Loans
or convert Loans of another Type to LIBOR Loans shall forthwith be suspended and
(b) the LIBOR Loans then outstanding shall be converted automatically to Prime
Rate Loans on the last day of each Interest Period applicable to such LIBOR
Loans or within such earlier period as may be required by law. The Borrower
hereby agrees promptly to pay to the Agent for the account of such Lender, upon
demand, any additional amounts necessary to compensate such Lender for any costs
incurred by such Lender in making any conversion in accordance with this
ss.4.11, including any interest or fees payable by such Lender to lenders of
funds obtained by it in order to make or maintain its LIBOR Loans hereunder. If,
at any time, the rate of interest, together with all amounts which constitute
interest and which are reserved, charged or taken by the Lenders as compensation
for fees, services or expenses incidental to the making, negotiating or
collection of the Loans or the other Obligations, shall he deemed by any
competent court of law, governmental agency or tribunal to exceed the maximum
rate of interest permitted to be charged by any Lender to Borrower under
applicable law, then, during such time as such rate of interest would be deemed
excessive, that portion of each sum paid attributable to that portion of such
interest rate that exceeds the maximum rate of interest so permitted shall be
deemed a voluntary prepayment of principal without penalty (including, without
limitation, prepayment fees required pursuant to Section 3.3(a) hereof). As used
herein, the term "applicable law" shall mean the law in effect as of the date
hereof, provided, however, that in the event there is a change in the law which
results in a higher permissible rate of interest, then this Agreement and the
Notes shall be governed by such new law as of its effective date.

     ss.4.12. Replacement of Lenders. If any of the Lenders shall make a notice
or demand upon the Borrower pursuant to ss.4.5, ss.4.6, or ss.4.11 based on
circumstances or laws which are not generally applicable to the Lenders
organized under the laws of the United States or any State thereof, the Borrower
shall have the right to replace such Lender with an Eligible Assignee selected
by the Borrower and approved by the Agent. In such event the assignment shall
take place on a date set by the Agent at which time the assigning Lender and the
Eligible Assignee shall enter into an Assignment and Acceptance as contemplated
by ss.18.1 (and clause (d) thereof shall not be applicable) and the assigning
Lender shall receive from the Eligible Assignee a sum equal to the outstanding
principal amount of the Loans owed to the assigning Lender together with accrued
interest thereon plus the accrued commitment fee under ss.4.2 allocated to the
assigning Lender, plus all other amounts then due to the assigning Lender
hereunder.

ss.5. COLLATERAL SECURITY; NO LIMITATION ON RECOURSE.

     ss.5.1. Collateral Security. The Obligations shall be secured by (i) a
perfected first priority lien and security interest to be held by the Agent
(subject only to Permitted Liens) in the Mortgaged Properties, pursuant to the
terms of the Security Documents, (ii) a perfected first priority lien and
security interest to be held by the Agent in the Leases and rents pursuant to
the Assignments of Leases and Rents, and (iii) a perfected first priority lien
and security interest to be held by the Agent in any cash collateral account
established pursuant to ss.2.8(f) or ss.5.6.

     ss.5.2. No Limitation on Recourse. Notwithstanding the foregoing
Collateral, the Obligations are full recourse obligations of the Borrower and
all of its Real Estate Assets and other properties shall be available for the
indefeasible payment in full in cash and performance of the Obligations.

     ss.5.3. Additional Properties. A Real Estate Asset owned by the Borrower or
by a Related Company that is to become a Guarantor may become an additional
Mortgaged Property if (i) all Lenders, in their sole discretion, approve such
Real Estate Asset and (ii) all of the conditions set forth in ss.5.4 are
satisfied with respect to such Real Estate Asset. Borrower shall provide the
Agent with a notice of each proposed Additional Property describing such
property, its estimated value and its estimated net operating income together
with a current rent roll and the most current operating statements available
with respect thereto, which operating statements, to the extent available, shall
cover a period of at least two years. If the Agent determines that additional
information is needed to sufficiently describe such property, it may request a
supplemental notice from the Borrower containing such additional information.
When such notice is satisfactory to the Agent, it shall send a copy to each
Lender and each Lender agrees to notify the Agent within ten (10) Business Days
after its receipt of such notice as to whether or not it approves of such Real
Estate Asset to become an Additional Property. If the notice distributed by the
Agent does not include copies of the Appraisal and/ or the environmental report
relating to such Real Estate Asset, then a Lender may grant a conditional
approval subject to its subsequent review of such items. When copies of such
Appraisal and/ or the environmental report are subsequently distributed each
Lender who has so conditioned its approval agrees to notify the Agent within ten
(10) Business Days after its receipt thereof as to whether the condition to its
approval has been satisfied. The fact that any Lender has so approved the
eligibility of a Real Estate Asset shall not prevent such Lender from
withholding any consent, approval or waiver required or requested of such Lender
in connection with the satisfaction or waiver of the conditions set forth in
ss.5.4 with respect to such Real Estate Asset. In the event that all Lenders
grant such approval and all of the conditions set forth in ss.5.4 are satisfied,
the Agent shall notify the Borrower and within thirty (30) days thereafter the
Borrower and the Mortgagor shall execute and deliver an Indemnity Agreement and
the Mortgagor shall execute and deliver to the Agent a Security Deed, an
Assignment of Rents and Leases, and Subordination, Attornment and
Non-Disturbance Agreements (to the extent required by the Agent in its
discretion), which Security Documents shall be in substantially the form of the
Security Documents executed and delivered herewith with such reasonable changes
as the Agent may deem desirable to address the laws of the State where the

                                      -30-

<PAGE>


Additional Property is located or the factual circumstances of the Additional
Property. If the Additional Property is not owned by the Borrower or an existing
Guarantor, but is owned by a Related Company which is 100% owned by Borrower,
such Related Company must become a Guarantor by delivery to the Agent of the
following, all in form and substance satisfactory to the Agent: (i) a Guaranty
in substantially the form of the Guaranty executed and delivered by the initial
Guarantors on the date of this Agreement and (ii) good standing certificates,
general partner certificates, secretary certificates, opinions of counsel and
such other documents as may be reasonably requested by the Agent. Such
Additional Properties shall be deemed to be Mortgaged Properties upon the
recording and filing of such Security Documents.

     ss.5.4. Conditions to Approval of Additional Properties. Prior to
acceptance of any Real Estate Asset to become an Additional Property pursuant to
ss.5.3, such property must satisfy the following conditions:

             (a) The Agent shall have received a certified Rent Roll, copies of
all Leases and estoppel certificates reasonably satisfactory to the Agent from
tenants occupying not less than 75% of the occupied square feet of the
Additional Property, and the Agent shall have received a Subordination,
Attornment and Non-Disturbance Agreements reasonably satisfactory to the Agent,
to the extent the Agent has requested the same.

             (b) An Appraisal of the Additional Property ordered by the Agent
and paid for by the Borrower shall have been approved by the Agent.

             (c) The Agent shall have received all of the items relating to the
Additional Property described in ss.10.8, ss.10.9, ss.10.10, ss.10.12, ss.10.13,
ss.10.14, ss.10.16 and ss.10.17 and such items shall have been approved by all
or some of the Lenders as required by such Sections.

             (d) The Agent shall have received a Certificate executed on behalf
of the Borrower containing the representations an warranties with respect to the
Additional Property as are set forth in ss.6.18 and ss.6.22.

             (e) The Agent shall have received updated certificates and other
items relating to the Borrower as described in ss.10.2, ss.10.3 and ss.10.4 and
a favorable opinion addressed to the Lenders and the Agent, in form and
substance substantially similar to the opinions delivered pursuant to ss.10.5,
relating to the Loan Documents executed by Borrower and or the Mortgagor with
respect to the Additional Property and relating to the laws of the state where
the Additional Property is located.

     ss.5.5. Release of Mortgaged Properties. The Borrower may request that the
Lenders authorize the Agent to release any Mortgaged Property from the lien of
the Security Documents and the Lenders agree to approve any such request
provided that the requested release will not result in any Default or Event of
Default under this Agreement and on or before the date of such release the
Borrower delivers to the Agent a pro-forma Compliance Certificate reasonably
satisfactory to the Agent demonstrating that the requested release, once
consummated, will not result in a violation of any of the covenants in ss.9.1
through ss.9.6

                                      -31-

<PAGE>


     ss.5.6. Chateau Plaza Reserve Account. On or before the date that Chateau
Plaza becomes a Mortgaged Property, the Borrower shall cause AmeriVest Chateau
Inc. to establish the Chateau Plaza Reserve Account at FNB and to enter into the
Collateral Account Agreement in form and substance satisfactory to the Agent.
Borrower acknowledges that for so long as FNB is the Agent hereunder, the Agent
shall be deemed to be in control of the Chateau Plaza Reserve Account as
required for perfection of said security interest under Article 9 of the Uniform
Commercial Code. In the event that the Agent is no longer FNB, Borrower, FNB and
the successor Agent shall enter into a control agreement for purposes of
maintaining such perfection. For so long as Chateau Plaza shall be a Mortgaged
Property, Borrower shall cause AmeriVest Chateau Inc. to make monthly deposits
on or before the 20th day of each month into the Chateau Plaza Reserve Account
equal to the excess of the Net Operating Income from Chateau Plaza for the
preceding calendar month over the sum of (i) interest for one month on a
principal amount of $15,400,000 at the actual average interest rate on the Loans
during such preceding month and (ii) $45,125.00 which is an assumed contribution
from Chateau Plaza toward the regular quarterly dividend on Borrower's common
stock, provided that in the event that the current quarterly dividend rate of
13.0 cents per share is increased or decreased, the monthly sum stated in this
clause (ii) shall be proportionately increased or decreased. On or before the
20th day of each month Borrower shall give to the Agent a written Deposit
Certificate in the form of Exhibit F hereto certifying the information used to
compute the amount of each monthly deposit. Any termination fees or other
consideration paid in connection with the termination of the current lease of
the Dean Foods Premises shall be immediately deposited in the Chateau Plaza
Reserve Account. If the existing Lease of the Dean Foods Premises terminates,
then to the extent that the Mortgagor of Chateau Plaza executes Leases of
portions of the Dean Foods Premises, Borrower may request periodic disbursements
from the Chateau Plaza Reserve Account in amounts needed to pay leasing
commissions and costs of tenant finish improvements constructed pursuant to the
terms of such Leases, and Agent shall make such disbursements subject to receipt
of lien waivers and other documents reasonably requested by the Agent. If an
Event of Default has occurred and is continuing, the Agent may, in its sole
discretion, apply any or all funds in the Chateau Plaza Reserve Account in the
same manner as Collateral proceeds under ss.12.4.

ss.6. REPRESENTATIONS AND WARRANTIES. The Borrower represents and warrants to
the Agent and each of the Lenders as of the Effective Date as follows.

     ss.6.1. Authority; Etc.

             (a) Organization; Good Standing. The Borrower (i) is a Maryland
corporation duly organized, validly existing and in good standing under the laws
of the State of Maryland, (ii) has all requisite power to own its properties and
conduct its business as now conducted and as presently contemplated, and (iii)
to the extent required by law is in good standing as a foreign entity and is
duly authorized to do business in the State of Colorado and in each other
jurisdiction where such qualification is necessary except where a failure to be
so qualified in such other jurisdiction would not have a Material Adverse
Effect. Each Guarantor is a limited partnership or a limited liability company
formed under the laws of the State in which the Mortgaged Property owned by it
is located or Delaware, and each such entity is duly organized, validly existing
and in good standing under the laws of the State of its formation, has all
requisite power to own its properties and conduct its business as presently

                                      -32-

<PAGE>


contemplated and is duly authorized to do business in the State in which the
Mortgaged Property owned by it is located and in each other jurisdiction where
such qualification is necessary.

             (b) Authorization. The execution, delivery and performance of this
Agreement and the other Loan Documents to which the Borrower is to become a
party and the transactions contemplated hereby and thereby (i) are within the
authority of the Borrower, (ii) have been duly authorized by all necessary
proceedings on the part of the Borrower, (iii) do not conflict with or result in
any breach or contravention of any provision of law, statute, rule or regulation
to which the Borrower is subject or any judgment, order, writ, injunction,
license or permit applicable to the Borrower and (iv) do not conflict with any
provision of its charter documents or bylaws of, or any agreement or other
instrument binding upon, the Borrower or to which any of its properties are
subject. The execution, delivery and performance of the Guaranty and the other
Loan Documents to which any Guarantor is or is to become a party and the
transactions contemplated hereby and thereby (i) are within the authority of
such Guarantor, (ii) have been duly authorized by all necessary proceedings on
the part of such Guarantor and its general partner or manager, (iii) do not
conflict with or result in any breach or contravention of any provision of law,
statute, rule or regulation to which such Guarantor is subject or any judgment,
order, writ, injunction, license or permit applicable to such Guarantor and (iv)
do not conflict with any provision of such Guarantor's charter documents or
bylaws, partnership agreement, limited liability company agreement, or any
agreement or other instrument binding upon such Guarantor or to which any of
such Guarantor's properties are subject.

             (c) Enforceability. Assuming due authorization, execution and
delivery by all other parties thereto, the execution and delivery of this

respect to all Leases of any portion of the Mortgaged Properties that is
accurate in all material respects is set forth in Schedule 6.20 as the same
shall be supplemented each fiscal quarter by a certificate signed by an
authorized officer of Borrower. The Leases reflected on such rent roll

to leasing or licensing of space in the Buildings or otherwise at the Mortgaged
Properties. The Borrower has delivered to the Agent a true and complete copy of
all Leases. There are no occupancies, rights, privileges or licenses in or to
the Buildings or any other part of the Mortgaged Properties other than pursuant
to the Leases reflected on Schedule 6.20. Except as set forth in Schedule 6.20
the Leases reflected thereon are in full force and effect, in accordance with
their respective terms, without any payment default or any other material
default thereunder, nor are there any material defenses, counterclaims, offsets,
concessions or rebates available to any tenant thereunder, and neither the
Borrower nor the Mortgagor has given or made, or received, any notice of
default, or any claim, which remains uncured or unsatisfied, with respect to any

tenant. The Schedule 6.20 rent roll accurately and completely sets forth all
rents payable by tenants, no tenant having paid more than one month's rent in
advance. All tenant improvements or work to be done, furnished or paid for by
the landlord, or credited or allowed to a tenant, for, or in connection with,
the Buildings pursuant to any Lease have been completed and paid for, or
provided for in a manner reasonably satisfactory to the Agent, or will be paid

leasing, brokerage or like commissions, fees or payments are due from the
Borrower or the Mortgagor in respect of the Leases, except those that will be
paid for by the Borrower or the Mortgagor in the ordinary course of its
business. Except as set forth on the Schedule 6.20 rent roll, all tenants under
all Leases are in occupancy and operating the premises covered by such Leases
within the permitted uses under such Leases.

appropriate proceedings and if the Borrower shall have set aside on its books
adequate reserves with respect thereto; and provided further that the Borrower
will pay all such taxes, assessments, charges, levies or claims forthwith upon
the commencement of proceedings to foreclose any lien that may have attached as
security therefor. Promptly after payment of real estate taxes, other taxes,

a Mortgaged Property (i) promptly following a written request from the Borrower,
(ii) at any time if required by bank regulatory requirements, (iii) at any time
if, in the opinion of the Agent, there may have been a material adverse change
in the Appraised Value of the applicable Mortgaged Property and (iv) during the
continuation of an Event of Default, if requested by any Lender. The Borrower
shall provide to the Agent all available information needed to assist in the
preparation of an Appraisal and shall pay to the Agent on demand all reasonable

not substantially in the form of Borrower's standard lease form previously
approved by the Agent, shall be submitted to and approved by the Agent prior to
execution, which approval shall not be unreasonably withheld, conditioned or
delayed. Any request to approve a Major Lease shall also include the most recent

new Lease, or of any amendment or modification of any Lease, shall be delivered
to the Agent promptly following execution of such Lease or Lease amendment.

Agent as agent for the Lenders.

Estate.

     ss.7.17. Environmental Indemnification. The Borrower covenants and agrees
that it will indemnify and hold the Agent and each Lender harmless from and
against any and all claims, expense, damage, loss or liability incurred by the
Agent or any Lender (including all reasonable costs of legal representation
incurred by the Agent or any Lender, but excluding, as applicable, for the Agent
or a Lender any claim, expense, damage, loss or liability as a result of the
gross negligence or willful misconduct of the Agent or such Lender) relating to
(a) any Release or threatened Release of Hazardous Substances on any Mortgaged
Property or any Real Estate; (b) any violation of any Environmental Laws with
respect to conditions at any Mortgaged Property or any Real Estate or the

Laws or to preserve the value of such Mortgaged Property or Real Estate.

     ss.7.19. Environmental Assessments. If the Agent in its good faith
judgment, after discussion with the Borrower, has reason to believe that the
environmental condition of any Mortgaged Property has deteriorated, after
reasonable notice by the Agent, whether or not a Default or an Event of Default
shall have occurred, the Agent may, from time to time, for the purpose of
assessing and ensuring the value of such Mortgaged Property, obtain one or more
environmental assessments or audits of such Mortgaged Property prepared by an
independent engineer or other qualified consultant or expert approved by the
Agent to evaluate or confirm (i) whether any Hazardous Substances are present in
the soil or water at such Mortgaged Property and (ii) whether the use and
operation of such Mortgaged Property complies with all Environmental Laws.
Environmental assessments may include without limitation detailed visual
inspections of such Mortgaged Property including, without limitation, any and
all storage areas, storage tanks, drains, dry wells and leaching areas, and the
taking of soil samples, surface water samples and ground water samples, as well
as such other investigations or analyses as the Agent deems appropriate. All

respects with the provisions of ERISA and, to the extent applicable, the Code,
including but not limited to the provisions thereunder respecting prohibited

Benefit Plan maintained by the Borrower or an ERISA Affiliate which is an
employee welfare benefit plan within the meaning of ss.3(1) or ss.3(2)(B) of
ERISA, the Borrower, or the ERISA Affiliate, as the case may be, has the right
to terminate each such plan at any time (or at any time subsequent to the
expiration of any applicable bargaining agreement) without liability other than
liability to pay claims incurred prior to the date of termination.

may, and upon the request of the Majority Lenders shall, by notice in writing to
the Borrower declare all amounts owing with respect to this Agreement, the Notes
and the other Loan Documents to be, and they shall thereupon forthwith become,
immediately due and payable without presentment, demand, protest or other notice
of any kind, all of which are hereby expressly waived by the Borrower; provided
that in the event of any Event of Default specified in ss.ss.12.1(g) or 12.1(h),

                                      -58-

<PAGE>


termination of such Lender's Commitment hereunder shall relieve the Borrower of
any of the Obligations or any of its existing obligations to such Lender arising
under other agreements or instruments.

     ss.12.3. Remedies. In case any one or more of the Events of Default shall
have occurred, and whether or not the Lenders shall have accelerated the
maturity of the Loans pursuant to ss.12.1, each Lender, if owed any amount with
respect to the Loans, may, with the consent of the Majority Lenders, direct the
Agent to proceed to protect and enforce the rights and remedies of the Agent and
the Lenders under this Agreement, the Notes or any of the other Loan Documents
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 to the full extent permitted by applicable
law the obtaining of the ex parte appointment of a receiver and, if any amount
shall have become due, by declaration or otherwise, to proceed to enforce the
payment thereof or any other legal or equitable right of such Lender. No remedy
herein conferred upon any Lender or the Agent or the holder of any Note 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 now
or hereafter existing at law or in equity or by statute or any other provision
of law.

case may be, receives any monies in connection with the enforcement of any of
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 Agent for or in respect of all reasonable costs, expenses,
disbursements and losses which shall have been incurred or sustained by the
Agent in connection with the collection of such monies by the Agent, for the
exercise, protection or enforcement by the Agent of all or any of the rights,
remedies, powers and privileges of the Agent or the Lenders 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 Agent against any taxes or liens
which by law shall have, or may have, priority over the rights of the Agent to
such monies;

              (b) Second, to all other Obligations in such order or preference
as the Majority Lenders may determine; provided, however, that distribution in
respect of such Obligations shall be made among the Lenders pro rata in
accordance with each Lender's respective Commitment Percentage; and provided,
further, that the Agent 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 Lenders and the Agent of all
of the obligations, and to the payment of any obligations required to be paid
pursuant to applicable laws applicable to such enforcement; and

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

     ss.12.5. Addition of Real Estate Assets to Cure Default. As an alternative
to the payment of cash to cure a Default under ss.9.1 or ss.9.2 hereof, the
Borrower shall have the right to offer to provide additional Collateral to the
Agent in the form of Additional Properties pursuant to ss.5.3 and ss.5.4, for
the purpose of curing a Default under ss.9.1 or ss.9.2 hereof, if the Borrower
designates such Collateral for addition within fifteen (15) days after the
occurrence of such Default and the Borrower executes and delivers to the Agent a
Security Deed, an Assignment of Leases and Rents, an Indemnity Agreement and
UCC-1 Financing Statements relating to the Additional Property together with the
Certificates and opinion described in ss.5.4(d) and ss.5.4(e) within thirty (30)
days after the occurrence of such Default. The Agent and the Lenders shall
accept and approve the addition of such Collateral as a cure for such Default if
such Collateral shall cure the Default and satisfies the due diligence
requirements of the Agent and the Lenders, including, without limitation, the
conditions set forth in ss.5.4 and those requirements with respect to the
Mortgaged Properties specified in ss.10 hereof, within ninety (90) days after
the occurrence of the subject Default, and at the time that such due diligence
requirements are so satisfied, no other Defaults or Events of Default are
continuing. If any such additional Collateral is provided to the Agent in
accordance with this ss.12.5, such additional Collateral shall, for all purposes
hereof, be deemed to be a "Mortgaged Property." Until the Agent and all Lenders
have acknowledged in writing the cure of such Default, all consequences of such
Default hereunder shall be effective (except as provided in ss.8.7) and the
Agent may exercise all available remedies except that the maturity of the Loans
shall not be accelerated based solely on the Default which Borrower is
diligently attempting to cure hereunder, prior to the expiration of said ninety
(90) day period.

ss.13. SETOFF. Borrower hereby grants to each Lender, a continuing lien,
security interest and right of setoff as security for all liabilities and
obligations to such Lender hereunder, whether now existing or hereafter arising,
upon and against all deposits, credits, collateral and property, now or
hereafter in the possession, custody, safekeeping or control of such Lender or
in transit to it. At any time, without demand or notice (any such notice being
expressly waived by Borrower), any Lender may, WITH THE PRIOR APPROVAL OF THE
AGENT, setoff the same or any part thereof and apply the same to any liability
or obligation of Borrower hereunder even though unmatured and regardless of the
adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO
REQUIRE ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER
COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF
SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER, ARE
HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Lenders agrees
with each other Lender that (a) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Lender, other than Indebtedness evidenced
by the Notes held by such Lender, such amount shall be applied ratably to such
other Indebtedness and to the Indebtedness evidenced by all such Notes held by
such Lender, and (b) if such Lender shall receive from the Borrower, whether by
voluntary payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Notes held by such Lender by
proceedings against the Borrower at law or in equity or by proof thereof in
bankruptcy, reorganization, liquidation, receivership or similar proceedings, or
otherwise, and shall retain and apply to the payment of the Note or Notes held
by such Lender any amount in excess of its ratable portion of the payments
received by all of the Lenders with respect to the Notes held by all of the

                                      -60-

Lenders, such Lender will make such disposition and arrangements with the other
Lenders with respect to such excess, either by way of distribution, pro tanto
assignment of claims, subrogation or otherwise as shall result in each Lender
receiving in respect of the Notes held by it its proportionate payment as
contemplated by this Agreement; provided that if all or any part of such excess
payment is thereafter recovered from such Lender, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest. Notwithstanding the foregoing, no Lender shall
exercise a right of setoff if such exercise would limit or prevent the exercise
of any other remedy, right to Collateral or other recourse against the Borrower.

ss.14. THE AGENT.

     ss.14.1. Authorization. The Agent is authorized to take such action on
behalf of each of the Lenders and to exercise all such powers as are hereunder
and under any of the other Loan Documents and any related documents delegated to
the Agent, together with such powers as are reasonably incident thereto,
provided that no duties or responsibilities not expressly assumed herein or
therein shall be implied to have been assumed by the Agent. The relationship
between the Agent and the Lenders is and shall be that of agent and principal
only, and nothing contained in this Agreement or any of the other Loan Documents
shall be construed to constitute the Agent as a trustee for any Lender.

     ss.14.2. Employees and Agents. The Agent may exercise its powers and
execute its duties by or through employees or agents and shall be entitled to
take, and to rely on, advice of counsel concerning all matters pertaining to its
rights and duties under this Agreement and the other Loan Documents. The Agent
may utilize the services of such Persons as the Agent in its sole discretion may
reasonably determine, and all reasonable fees and expenses of any such Persons
shall be paid by the Borrower.

     ss.14.3. No Liability. Neither the Agent nor any of its shareholders,
directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee thereof, shall be liable for any waiver,
consent or approval given or any action taken, or omitted to be taken, in good
faith by it or them hereunder or under any of the other Loan Documents, or in
connection herewith or therewith, or be responsible for the consequences of any
oversight or error of judgment whatsoever, except that the Agent or such other
Person, as the case may be, may be liable for losses due to its willful
misconduct or gross negligence.

     ss.14.4. No Representations. The Agent shall not be responsible for the
execution or validity or enforceability by or against Borrower or Guarantor of
this Agreement, the Notes, any of the other Loan Documents or any instrument at
any time constituting, or intended to constitute, collateral security for the
Notes, or for the value of any such collateral security or for the validity,
enforceability or collectability of any such amounts owing with respect to the
Notes, or for any recitals or statements, warranties or representations made
herein or in any of the other Loan Documents or in any certificate or instrument
hereafter furnished to it by or on behalf of the Borrower, or be bound to
ascertain or inquire as to the performance or observance of any of the terms,
conditions, covenants or agreements herein or in any instrument at any time
constituting, or intended to constitute, collateral security for the Notes. The
Agent shall not be bound to ascertain whether any notice, consent, waiver or
request delivered to it by the Borrower or any holder of any of the Notes shall

                                      -61-

<PAGE>


have been duly authorized or is true, accurate and complete. The Agent has not
made nor does it now make any representations or warranties, express or implied,
nor does it assume any liability to the Lenders, with respect to the credit
worthiness or financial condition of the Borrower. Each Lender acknowledges that
it has, independently and without reliance upon the Agent or any other Lender,
and based upon such information and documents as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement. Agent's
counsel has only represented Agent and FNB in connection with the Loan Documents
and the only attorney-client relationship or duty of care is between Agent's
counsel and Agent or FNB. Each Lender has been independently represented by
separate counsel on all matters regarding the Loan Documents and the granting
and perfecting of liens in the Collateral.

     ss.14.5. Payments.

              (a) A payment by the Borrower to the Agent hereunder or any of the
other Loan Documents for the account of any Lender (other than payments of
issuance and renewal fees to the Agent with respect to Letters of Credit) shall
constitute a payment to such Lender subject to the pro rata rights to repayment
based upon the Commitment Percentage of each Lender. The Agent agrees promptly
to distribute to each Lender such Lender's pro rata share of payments received
by the Agent for the account of the Lenders except as otherwise expressly
provided herein or in any of the other Loan Documents.

              (b) If in the opinion of the Agent the distribution of any amount
received by it in such capacity hereunder, under the Notes or under any of the
other Loan Documents might involve it in liability, it may refrain from making
distribution until its right to make distribution shall have been adjudicated by
a court of competent jurisdiction. If a court of competent jurisdiction shall
adjudge that any amount received and distributed by the Agent is to be repaid,
each Person to whom any such distribution shall have been made shall either
repay to the Agent its proportionate share of the amount so adjudged to be
repaid or shall pay over the same in such manner and to such Persons as shall be
determined by such court.

              (c) Notwithstanding anything to the contrary contained in this
Agreement or any of the other Loan Documents, any Lender that fails (i) to make
available to the Agent its pro rata share of any Loan or (ii) to comply with the
provisions of ss.12 and ss.13 with respect to making dispositions and
arrangements with the other Lenders, where such Lender's share of any payment
received, whether by setoff or otherwise, is in excess of its pro rata share of
such payments due and payable to all of the Lenders, in each case as, when and
to the full extent required by the provisions of this Agreement, or to adjust
promptly such Lender's outstanding principal and its pro rata Commitment
Percentage as provided in ss.2.1 hereof, shall be deemed delinquent (a
"Delinquent Lender") and shall be deemed a Delinquent Lender until such time as
such delinquency is satisfied. A Delinquent Lender shall be deemed to have
assigned any and all payments due to it from the Borrower, whether on account of
outstanding Loans, interest, fees or otherwise, to the remaining nondelinquent
Lenders for application to, and reduction of, their respective pro rata shares
of all outstanding Loans. The Delinquent Lender hereby authorizes the Agent to
distribute such payments to the nondelinquent Lenders in proportion to their
respective pro rata shares of all outstanding Loans. A Delinquent Lender shall
be deemed to have satisfied in full a delinquency when and if, as a result of
application of the assigned payments to all outstanding Loans of the

                                      -62-

<PAGE>


nondelinquent Lenders, the Lenders respective pro rata shares of all outstanding
Loans have returned to those in effect immediately prior to such delinquency and
without giving effect to the nonpayment causing such delinquency.

     ss.14.6. Holders of Notes. The Agent may deem and treat the payee of any
Note as the absolute owner or purchaser thereof for all purposes hereof until it
shall have been furnished in writing with a different name by such payee or by a
subsequent holder assignee or transferee.

     ss.14.7. Indemnity. The Lenders ratably agree hereby to indemnify and hold
harmless the Agent from and against any and all claims, actions and suits
(whether groundless or otherwise), losses, damages, costs, expenses (including
any expenses for which the Agent has not been reimbursed by the Borrower as
required by ss.15), and liabilities of every nature and character arising out of
or related to this Agreement, the Notes, or any of the other Loan Documents or
the transactions contemplated or evidenced hereby or thereby, or the Agent's
actions taken hereunder or thereunder, except to the extent that any of the same
shall be directly caused by the Agent's willful misconduct or gross negligence.

     ss.14.8. Agent as Lender. In its individual capacity, FNB shall have the
same obligations and the same rights, powers and privileges in respect to its
Commitment and the Loans made by it, and as the holder of any of the Notes as it
would have were it not also the Agent.

     ss.14.9. Resignation and Removal. The Agent may resign at any time by
giving sixty (60) days, prior written notice thereof to the Lenders and the
Borrower. Upon any such resignation, the Majority Lenders shall have the right
to appoint a successor Agent. Unless a Default or Event of Default shall have
occurred and be continuing, appointment of such successor Agent shall be subject
to the reasonable approval of the Borrower. If no successor Agent shall have
been so appointed by the Majority Lenders and shall have accepted such
appointment within thirty (30) days after the giving of notice of resignation or
removal of the Borrower has disapproved or failed to approve a successor agent
within such period, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, which shall be a financial institution having a
rating of not less than A2/P2 or its equivalent by Standard & Poor's
Corporation. Upon the acceptance of any appointment as Agent hereunder by a
successor Agent, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder. Such successor Agent shall issue replacement Letters of Credit and
any outstanding Letters of Credit issued by the retiring Agent shall be canceled
and returned to it. After any retiring Agent's resignation, the provisions of
this Agreement and the other Loan Documents shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

     ss.14.10. Notification of Defaults and Events of Default. Each Lender
hereby agrees that, upon learning of the existence of a Default or an Event of
Default, it shall promptly notify the Agent thereof. The Agent hereby agrees
that upon receipt of any notice under this ss.14.10 it shall promptly notify the
other Lenders of the existence of such Default or Event of Default.

                                      -63-

<PAGE>


     ss.14.11. Duties in the Case of Enforcement. In case one of more Events of
Default have occurred and shall be continuing, and whether or not acceleration
of the obligations shall have occurred, the Agent shall, if (a) so requested by
the Majority Lenders and (b) the Lenders have provided to the Agent such
additional indemnities and assurances against expenses and liabilities as the
Agent may reasonably request, proceed to enforce the provisions of the Security
Documents authorizing the sale or other disposition of all or any part of the
Collateral and exercise all or any such other legal and equitable and other
rights or remedies as it may have in respect of such Collateral. The Majority
Lenders may direct the Agent in writing as to the method and the extent of any
such sale or other disposition, the Lenders hereby agreeing to indemnify and
hold the Agent harmless from all liabilities incurred in respect of all actions
taken or omitted in accordance with such directions, provided that the Agent
need not comply with any such direction to the extent that the Agent reasonably
believes the Agent's compliance with such direction to be unlawful or
commercially unreasonable in any applicable jurisdiction. The Agent may take
such steps as it reasonably determines for the taking of possession or title to
any Collateral, including the formation of trusts, limited liability companies
or corporations with each Lender having a beneficial interest equal to its pro
rata percentage of the outstanding Loans.

ss.15. EXPENSES. The Borrower agrees to pay (a) any taxes (including any
interest and penalties in respect thereto) payable by the Agent or any of the
Lenders (other than taxes based upon the Agent's or any Lender's net income),
including any recording, mortgage, documentary or intangibles taxes in
connection with the Security Documents and other Loan Documents, or other taxes
payable on or with respect to the transactions contemplated by this Agreement,
including any taxes payable by the Agent or any of the Lenders after the
Effective Date (the Borrower hereby agreeing to indemnify the Lenders with
respect thereto), (b) all title insurance premiums, appraisal fees, engineer's,
inspector's and surveyor's fees, recording costs and the reasonable fees,
expenses and disbursements of the Agent's counsel or any local counsel to the

each closing hereunder, and amendments, modifications, approvals, consents or
waivers hereto or hereunder, (c) the reasonable fees, costs, expenses and
disbursements of the Agent incurred in connection with the preparation,

costs, expenses and disbursements of the Agent incurred in connection with the
syndication and/or participation of the Loans in the event that Borrower shall
request an increase in the Total Commitment, (e) all reasonable out-of-pocket
expenses (including reasonable attorneys' fees and costs, which attorneys may be
employees of any Lender or the Agent and the fees and costs of appraisers,
engineers, investment bankers, surveyors or other experts retained by the Agent
or any Lender in connection with any such enforcement proceedings) incurred by

preservation of rights under any of the Loan Documents against the Borrower or
the administration thereof after the occurrence of a Default or Event of Default
(including, without limitation, expenses incurred in any restructuring and/or
"workout" of the Loans), and (ii) any litigation, proceeding or dispute whether
arising hereunder or otherwise, in any way related to the Agent's or the
Lender's relationship with the Borrower, any Controlled Unconsolidated Entity or
any of the Related Companies, (f) all reasonable fees, expenses and
disbursements of the Agent incurred in connection with UCC searches, UCC filings

                                      -64-

future in connection with its inspection of the Mortgaged Properties, and (h)
the reasonable fees, costs, expenses and disbursements of the Agent incurred in
connection with the granting of additional Collateral by the Borrower pursuant
to ss.5.3 or ss.12.5 hereof, including, without limitation, the costs incurred
by the Agent in connection with its inspection of such additional Collateral,
and the fees and disbursements of the Agent's counsel. The covenants of this
ss.15 shall survive payment or satisfaction of payment of amounts owing with
respect to the Notes.

ss.16. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the
Agent and the Lenders and the shareholders, directors, agents, officers,
subsidiaries, and affiliates of the Agent and the Lenders from and against any
and all claims, actions or causes of action and suits whether groundless or
otherwise, and from and against any and all Liabilities, losses, settlement
payments, obligations, 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 or which otherwise arise in connection with the
financing including, without limitation except to the extent caused by the gross
negligence or willful misconduct of a Lender or the Agent (but such limitation
on indemnification shall only apply to the Agent or Lender that is being grossly
negligent or committing willful misconduct), (a) any actual or proposed use by
the Borrower of the proceeds of any of the Loans, (b) any actual or alleged
infringement of any patent, copyright, trademark, service mark or similar right
of the Borrower comprised in the Collateral, (c) the Borrower entering into or
performing this Agreement or any of the other Loan Documents or (d) with respect
to the Borrower and its respective properties, the violation of any

or any action, suit, proceeding or investigation brought or threatened with
respect to any Hazardous Substances (including, but not limited to claims with
respect to wrongful death, personal injury or damage to property), (e) any cost,
claim liability, damage or expense in connection with any harm the Borrower may
be found to have caused in the role of a broker, in each case including, without
limitation, the reasonable fees and disbursements of counsel and allocated costs
of internal counsel incurred in connection with any such investigation,
litigation or other proceeding. In litigation, or the preparation therefor, the
Lenders and the Agent shall each be entitled to select their own separate
counsel and, in addition to the foregoing indemnity, the Borrower agrees to pay
promptly the reasonable fees and expenses of such counsel. If, and to the extent
that the obligations of the Borrower under this ss.16 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. The provisions of this ss.16 shall survive the repayment of the
Loans and the termination of the obligations of the Lenders hereunder and shall
continue in full force and effect as to the Lenders so long as the possibility
of any such claim, action, cause of action or suit exists under applicable law,
rule or regulation.

ss.17. SURVIVAL OF COVENANTS, ETC. All covenants, agreements, representations
and warranties made herein, in the Notes, in any of the other Loan Documents or
in any documents or other papers delivered by or on behalf of the Borrower
pursuant hereto shall be deemed to have been relied upon by the Lenders and the
Agent, notwithstanding any investigation heretofore or hereafter made by it, and
shall survive the making by the Lenders of the Loans, as herein contemplated,
and shall continue in full force and effect so long as any amount due under this
Agreement or the Notes or any of the other Loan Documents remains outstanding or

                                      -65-

<PAGE>


the Lenders have any obligation to make any Loans. The indemnification
obligations of the Borrower provided herein and the other Loan Documents shall
survive the full repayment of amounts due and the termination of the obligations
of the Lenders hereunder and thereunder to the extent provided herein and
therein. All statements contained in any certificate delivered to the Agent or

constitute representations and warranties by the Borrower hereunder.

shall constitute one instrument. In proving this Agreement it shall not be
necessary to produce or account for more than one such counterpart signed by the

ss.23. ENTIRE AGREEMENT. This Agreement and the Loan Documents is intended by
the parties as the final, complete and exclusive statement of the transactions
evidenced by this Agreement and the Loan Documents. All prior or contemporaneous
promises, agreements and understandings, whether oral or written, are deemed to
be superceded by this Agreement and the Loan Documents, and no party is relying
on any promise, agreement or understanding not set forth in this Agreement and
the Loan Documents. Neither this Agreement nor any term hereof may be changed,
waived, discharged or terminated, except as provided in ss.25.

ss.24. WAIVER OF JURY TRIAL AND CERTAIN DAMAGE CLAIMS. THE BORROWER, THE AGENT
AND EACH LENDER HEREBY MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING
OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENTS
CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT,
COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY
PARTY, INCLUDING, WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS,
STATEMENTS OR ACTIONS OF BANK RELATING TO THE ADMINISTRATION OF THE LOANS OR
ENFORCEMENT OF THE LOAN DOCUMENTS, AND AGREE THAT NO PARTY WILL SEEK TO
CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT
BE OR HAS NOT BEEN WAIVED. EXCEPT AS PROHIBITED BY LAW, BORROWER HEREBY WAIVES
ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ANY SPECIAL,
EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN
ADDITION TO, ACTUAL DAMAGES. BORROWER CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF AGENT OR ANY LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
AGENT OR ANY LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR LENDERS TO
PROVIDE THE COMMITMENTS AND MAKE THE LOANS.

ss.25. CONSENTS, AMENDMENTS, WAIVERS, ETC. Any consent or approval required or
permitted by this Agreement may be given, and any term of this Agreement or of
any other instrument related hereto or mentioned herein may be amended, and the

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 Majority Lenders,
and, in the case of amendments, with the written consent of the Borrower other
than amendments to schedules made in the ordinary course as contemplated by this
Agreement, provided, however, that any waiver of an Event of Default under
ss.12.1(a) or ss.12.1(b) or any modifications or waivers of the financial
covenants set forth in ss.9.1, ss.9.2 or ss.9.3 or any waiver of an Event of
Default relating to the Borrower's failure to comply with such financial
covenants shall require the written consent of all Lenders. Notwithstanding the

foregoing, (i) the rate of interest on and the term or amount of the Notes, (ii)
the amount of the Commitments of the Lenders(other than changes in Commitments
pursuant to Assignments under ss.18 or pursuant to changes in the Total
Commitment under ss.2.2), (iii) the amount of any fee payable to a Lender
hereunder, (iv) any provision herein or in any of the Loan Documents which
expressly requires consent of all the Lenders, (v) the funding provisions of
ss.2.5 and ss.2.7 hereof, (vi) the Maturity Date and (vii) the rights, duties
and obligations of the Agent specified in ss.14 hereof, may not be amended
without the written consent of each Lender affected thereby, nor may the Agent
release any Collateral or add any Collateral, including pursuant to ss.12.5
hereof, without first obtaining the written consent of all the Lenders. 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 Agent or any Lender in exercising any right shall operate as a
waiver thereof or otherwise be prejudicial thereto. No notice to or demand upon
the Borrower shall entitle the Borrower to other or further notice or demand in
similar or other circumstances.

ss.26. SEVERABILITY. The provisions of this Agreement are severable, and if any
one 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.

                                    ---------

                          Compliance Certificate under
            Revolving Credit Agreement dated as of November 12, 2002

     The undersigned, a Responsible Officer of AMERIVEST PROPERTIES INC. (the
"Borrower"), hereby certifies on behalf of the Borrower as of the date hereof
the following:

     1. No Defaults. I have read a copy of the Revolving Credit Agreement dated
as of November , 2002 (the "Credit Agreement") among the Borrower, Fleet
National Bank, the other lending institutions party thereto, and Fleet National
Bank, as Agent. Terms used herein and not otherwise defined herein shall have
the meanings set forth in ss.1.1 of the Credit Agreement. No Event of Default is
continuing in the performance or observance of any of the covenants, terms or
provisions of the Credit Agreement or any of the other Loan Documents. Without
limiting the foregoing, the Borrower has not taken any actions which are
prohibited by the negative covenants set forth in ss.8 of the Credit Agreement.
Attached hereto as Appendix I are all relevant calculations needed to determine
whether the Borrower is in compliance with ss.9.1 through ss.9.6, inclusive, and
ss.8.3(d) of the Credit Agreement as of the end of the most recently completed
fiscal quarter (except that in the case of Compliance Certificates delivered
pursuant to ss.2.5, ss.2.8(a), ss.5.5, ss.8.1(f), ss.8.4(c), or ss.11.1, the
calculations determining compliance with ss.9.1 through ss.9.3 have been
computed on a pro forma basis after giving effect to the proposed transaction)
and is in compliance with ss.8.7 of the Credit Agreement for the most recently
completed fiscal year.

     2. No Material Changes, Etc. Except as disclosed on Appendix II hereto,
since the [date of most recent financial statements furnished to the Agent and
the Lenders], there have occurred no materially adverse changes in the financial
condition or business of the Borrower as shown on or reflected in the balance
sheet of the Borrower as at such date other than (a) changes in the ordinary
course of business that have not had any materially adverse effect either
individually or in the aggregate on the business or financial condition of the
Borrower and (b) changes resulting from the making of the Loans and the
transactions contemplated by the Credit Agreement.

     3. No Materially Adverse Contracts, Etc. The Borrower is not subject to any
charter, corporate, or other legal restriction, or any judgment, decree, order,
rule or regulation that has or is expected, in the reasonable judgment of the
Borrower 's officers, in the future to have a materially adverse effect on the
Borrower or the Collateral. The Borrower is not a party to any contract or
agreement that has or is expected, in the reasonable judgment of the Borrower 's
officers, to have a materially adverse effect on the Borrower or the Collateral.

Date:

including exemplary damages, and pre- and post-judgment interest as provided by
law, costs of the lawsuit and such other relief to which the plaintiff may be

Asset Purchases and Sales Involving Related Parties

    Keystone Land Purchase

     In September 2002, we purchased from Sheridan Realty Partners, L.P., which
is owned by certain of our executive officers and directors, 2.55 acres of
vacant land adjacent to Keystone Office Park for a total purchase price of
$320,000 paid in the form of our common stock.

    Sale of Interest in Panorama Falls Building

     On December 6, 2001, we completed the sale of an undivided 80% interest in
the Panorama Falls building to Freemark Abbey Panorama, LLC. A partner in
Freemark Abbey is an indirect beneficial owner of approximately 9% of Sheridan
Investments, LLC, which is the beneficial owner of approximately 18% of our
common stock. The aggregate sale price for the interest in Panorama Falls was
$4,800,000 payable by the Freemark Abbey as follows:

   o  $2,180,000 to KeyBank National Association to pay down a portion of the
      existing mortgage loan;

   o  the assumption of 80% of the remaining existing mortgage loan in the
      amount of $2,395,732; and

   o  the remainder of $304,268, less closing costs, in cash to us.

     We retained a 20% interest in the property and will continue to operate and
manage the property. We will earn a management fee equal to 5% of the gross
revenues and an incentive fee from Freemark Abbey based on the total return of

<PAGE>


the investment. The incentive fee is calculated as 25% of the cash remaining
after both parties have received distributions equal to their initial
investments in the property plus a 12% annually compounded cumulative return.

    Purchase of Sheridan Plaza at Inverness, LLC

     On June 25, 2001, we purchased 100% of the ownership interests of Sheridan
Plaza at Inverness, LLC from Sheridan Investments. Sheridan Plaza at Inverness,
LLC owns two office buildings located in Englewood, Colorado consisting of
118,720 rentable square feet on approximately 6.7 acres of land with 405 total
parking spaces, including 80 underground parking spaces. For accounting
purposes, the purchase price was $22,895,067, which consisted of:

   o  $705,135 for our 9.639% preferred membership interest in Sheridan
      Investments, LLC, the owner of all of o the membership interests in
      Sheridan Plaza at Inverness LLC, which was transferred back to Sheridan
      Investments, LLC;

   o  $6,474,329 paid with (1) 1,057,346 shares of our common stock at a price
      of $5.69 per share (as required for accounting purposes, based on an
      average market price of the shares over a period of several days

   o  before and after the date of the announcement of the acquisition) and (2)
      the cash proceeds of $458,030 from the sale of the Giltedge building;

   o  assumption of the mortgage in the principal amount of $14,954,425 secured
      by the property; and

   o  assumption of other liabilities in the approximate amount of $761,178.

     We used the $458,030 in net cash proceeds from the sale of the Giltedge
building to pay a portion of the purchase price for Sheridan Plaza at Inverness,
LLC as part of an Internal Revenue Code Section 1031 tax-deferred exchange. We
received stockholder approval for this transaction at a meeting held on June 20,
2001. As a result of the completion of this transaction, Sheridan Realty
Advisors was entitled to a fee of $294,700, which is equal to 5% of the equity
value of Sheridan Plaza at Inverness, LLC, in accordance with the terms of our
advisory agreement with Sheridan Realty Advisors.

     Due to the fact that this transaction involved a related party, the
acquisition was recorded at its historical net book value. The difference
between the purchase price and the historical net book value was $4,507,557 and
has been recorded as a non-cash dividend during 2001.

    Purchase of Sheridan Investments, LLC Interest

     Effective July 1, 2000, we purchased from Sheridan Realty Partners a 9.639%
preferred membership interest in Sheridan Investments, through our wholly-owned
subsidiary, AmeriVest Inverness Inc. Sheridan Investments owned all the
ownership interests of Sheridan Plaza at Inverness, LLC, which owned a fee
simple interest in Sheridan Plaza at Inverness and related assets. The purchase
price of the membership interest was $658,918 payable in the form of 65,892
units, with each unit consisting of two shares of our common stock and one
redeemable warrant to purchase one share of our common stock for $5.00 per share
until July 10, 2005. These warrants were exercised by Sheridan Realty Partners
in March 2001. The agreement also provided for a reduction to the purchase price
if, on or before October 31, 2000, a member of Sheridan Investments sold a
preferred membership interest at a price less than the purchase price paid by us
or Sheridan Investments issued additional preferred membership interests with
substantially the same terms as our membership interest at a price less than the
purchase price paid by us. No such transaction occurred and no reduction in the
purchase price took place. As a result of our purchase of the interest in
Sheridan Investments, Sheridan Realty Advisors was entitled to a fee of $32,946,
which is equal to 5% of the equity value of that interest, in accordance with
our advisory agreement with Sheridan Realty Advisors.

    Purchase of Panorama Falls Property

     In order to pay a portion of the purchase price for the Panorama Falls
property on May 25, 2000, we borrowed $225,000 from the Hewitt Trust, using
$200,000 in connection with the purchase. This loan accrued interest at the
prime rate, was due on demand after one year or five days after the closing of
our 2000 public offering of units of common stock and warrants with proceeds to
us of at least $2 million, and was unsecured. We repaid this loan in August 2000
with the proceeds of our public offering. Alexander S. Hewitt is a stockholder
and officer of AmeriVest, an owner and officer of various Sheridan Group
companies and a trustee and beneficiary of the Hewitt Trust.

Line of Credit with Sheridan Investments, LLC

     On June 13, 2001, our Board of Directors approved our obtaining a $500,000
one-year line of credit from Sheridan Investments. On March 11, 2002, the Board
approved an increase in this line of credit to $1,500,000. As of April 30, 2002,
we had an outstanding balance of $1,000,000 on this line of credit. This line of
credit, which is unsecured and has a rate of interest equal to 75 basis points
above the prevailing prime rate charged by Ferris, Baker Watts, provides us with
additional liquidity on terms that are more favorable to us than our continuing
line of credit with US Bank. Among the more favorable terms are the lack of fees
and the unsecured nature of this line of credit. Our line of credit with US Bank
is secured by a second mortgage on our Sheridan Center property and a negative
pledge on the assets of our AmeriVest Buildings Texas Inc. subsidiary, with an
interest rate equal to one point over that bank's prime lending rate.

Purchase of Key Man Life Insurance Policy

     In 2000, we purchased from Sheridan Investments the key man life insurance
policy maintained on the life of William T. Atkins, our Chairman and Chief
Executive Officer. We paid $79,376 for this policy, which was the excess of the
cash value of the policy over the total loan outstanding on the policy. We paid
this purchase price by issuing shares of our common stock valued at a price
equal to the volume-weighted average trading price of our common stock for the
five most recent trading days preceding December 18, 2000. This resulted in the
issuance of 16,305 shares of our common stock valued at $4.868 per share.

Agreements with Sheridan Realty Advisors, LLC

     Effective January 1, 2000, we entered into an agreement with Sheridan
Realty Advisors for it to act as our administrator and to assume responsibility
for our day-to-day operations. This agreement was amended and restated in March
2001 and was further amended and restated as of January 1, 2002 to reduce the
types of services provided to AmeriVest and the fees paid by AmeriVest to
Sheridan Realty Advisors as a result of our purchase of the administrative,
property management and accounting services business from Sheridan Realty
Advisors, as described in more detail below.

     Prior to the amendment and restatement of the advisory agreement effective
as of January 1, 2002, we paid Sheridan Realty Advisors a monthly administrative
fee of $15,800, which was to increase annually by 5%, a property management and
accounting fee equal to 5% of the gross collected rents received by us from the
managed properties, and a capital project fee equal to 3% of the total cost of
all capital projects in excess of $100,000 and approved by us. In addition,
Sheridan Realty Advisors was entitled to an advisory fee equal to 5% of the
equity value of all real property acquired or long-term leased by AmeriVest
during the term of the agreement. Equity value is equal to the acquisition price
of the property, including expenses of purchase, plus any capital expenditures
and lease-up costs incurred in connection with the property during the first 12
months of ownership less any mortgage debt assumed or incurred in connection
with the acquisition. This fee was intended to cover overhead expenses of
Sheridan Realty Advisors not covered by the other fees paid by AmeriVest and is
limited to amounts set forth in an annual budget submitted to AmeriVest.

     In addition, Sheridan Realty Advisors received incentive compensation in
the form of five-year warrants to purchase up to 750,000 shares of our common
stock at $5.00 per share. The warrants were issued as of January 1, 2000, and
225,000 warrants vested immediately after approval of the issuance of the
warrants by our stockholders on June 6, 2000. Sheridan Realty Advisors may
utilize the warrants as incentive compensation to its employees. Vested warrants
may only be exercised beginning on January 1, 2003. The remaining 525,000

<PAGE>


warrants vest only upon the completion of an acquisition or long-term lease of
real property by us. During the year ended December 31, 2001, Sheridan Realty
Advisors had approximately 387,662 warrants vest under this agreement. As of
March 31, 2002, 436,457 of the remaining 525,000 warrants had vested. For a more
detailed description of the warrant arrangements with Sheridan Realty Advisors
under the advisory agreement, see "Executive Compensation--Sheridan Realty
Advisors, LLC Warrants."

     As of December 31, 2001, we had no direct employees. At that date, Sheridan
Realty Advisors had 31 employees who spent the majority of their time on our
business. All five of our executive officers were employed by Sheridan Realty
Advisors and received all of their cash or deferred compensation, health
insurance benefits and reimbursement of approved business expenses from Sheridan
Realty Advisors. In addition, our executive officers, who are also owners of
Sheridan Realty Advisors, were entitled to receive a portion of the five-year
incentive warrants described above. In 2001, our five executive officers earned
aggregate cash or deferred compensation of $780,000 from Sheridan Realty
Advisors, with each executive officer receiving compensation paid or deferred in
excess of $100,000. As of March 31, 2002, we had an outstanding balance of
$513,852 payable to Sheridan Realty Advisors in connection with previously
performed services. Under an agreement between us and Sheridan Realty Advisors
dated June 27, 2001, we do not have an obligation to pay any of this outstanding
balance until July 27, 2002.

     Effective as of January 1, 2002, we purchased the administrative and
property management and accounting services business from Sheridan Realty
Advisors for the sum of $100 plus the book value of the furniture, fixtures and
equipment at December 31, 2001, which was approximately $50,000. Three of our
senior executives and 22 of the other employees of Sheridan Realty Advisors
became our direct employees and manage our day-to-day operations. We agreed to
assume sponsorship of, and all assets of and liabilities attributable to, the
transferred employees under the employee benefit plans of Sheridan Realty
Advisors. The three senior executives who became our employees, William T.
Atkins, our Chief Executive Officer, Charles K. Knight, our President, and D.
Scott Ikenberry, our Chief Financial Officer, will also remain employees of
Sheridan Realty Advisors and their 2002 salary obligations will be shared
between us and Sheridan Realty Advisors such that we will pay their cash
compensation and Sheridan Realty Advisors will accrue their deferred
compensation as a liability of Sheridan Realty Advisors.

     In connection with our purchase of the administrative and property
management and accounting services business from Sheridan Realty Advisors, we
amended and restated our advisory agreement with Sheridan Realty Advisors as of
December 31, 2001 and became a self-administered REIT. Sheridan Realty Advisors
continues to serve as an outside advisor to the company in connection with
capital market activities, real estate acquisitions and dispositions and major
capital projects. For these services, Sheridan Realty Advisors will continue to
earn an advisory fee equal to 5% of the equity value of all real property
acquired or long-term leased by us and a capital project fee equal to 3% of the
total cost of all capital projects in excess of $100,000 and approved by us, as
well as continued vesting of the warrants. The amended and restated advisory
agreement expires on December 31, 2003 unless terminated earlier. The agreement
may be terminated upon 120 days' notice by a majority of our directors who are
not affiliated with Sheridan Realty Advisors or by a vote of a majority of our
stockholders. In addition, we may terminate the agreement without penalty and
without advance notice to Sheridan Realty Advisors upon a material change in the
ownership, control or management of Sheridan Realty Advisors. The agreement
provides that the resignation of either Mr. Atkins or Mr. Knight from Sheridan
Realty Advisors without our prior approval will be deemed a material change in
control of Sheridan Realty Advisors.

Conflicts of Interest Policies

     Our Board of Directors and our officers are subject to certain provisions
of Maryland law which are designed to eliminate or minimize the effects of
certain potential conflicts of interest. In addition, our bylaws provide that
any transaction between us and an interested party must be fully disclosed to
our Board, and that a majority of the directors not otherwise interested in the
transaction (including a majority of independent directors) must make a
determination that the transaction is fair, competitive and commercially
reasonable and on terms and conditions not less favorable to us than those
available from unaffiliated third parties.

     Other than as described in this section, there are no material
relationships between us and our directors, executive officers or known holders
of more than 5% of our common stock.
