     Section 2. REVOLVING CREDIT FACILITY.

     Section 2.1. Commitment to Lend; Limitation on Total Commitment. Subject
to the provisions of Section 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 in accordance with Section 2.5, such sums as are requested
by the Borrower up to a maximum aggregate principal amount of the 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 Section 10 or Section 11 (whichever is
applicable) have been satisfied 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 Requisite Lenders
that such conditions have not been satisfied.

     Section 2.2. Changes 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 $300,000,000 by written notice to the Agent.
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 in its sole discretion to provide an
Additional Commitment upon such terms shall provide Agent with a written
commitment letter specifying the amount of the Additional Commitment 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").

          (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 Base Rate Loans until
converted to LIBOR Rate 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 Rate 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 Fixed Rate Prepayment
Fee which shall be determined separately for each such Lender in the manner
set forth in Section 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 Section 2.9(c) prorated for the period from
the Commitment Increase Date until the expiration of the applicable Letter of
Credit.

          (c) The Borrower shall have the right at any time upon at least ten
(10) Business Days' prior written notice to the Agent (which shall promptly
notify each Lender), to reduce by $5,000,000 or an integral multiple of
$1,000,000 in excess thereof the unborrowed portion of the then Total
Commitment, provided that the Total Commitment shall not be reduced to less
than $150,000,000, whereupon the Commitments of the Lenders shall be reduced
pro rata in accordance with their respective Commitment Percentages by the
amount specified in such notice. Upon the effective date of any such
reduction, the Borrower shall pay to the Agent for the respective accounts of
the Lenders the full amount of any commitment fee required under Section 4.2
hereof then accrued and unpaid on the amount of the reduction. No reduction of
the Commitments may be reinstated.

          (d) Upon the effective date of each increase or reduction in the
Total Commitment pursuant to this Section 2.2 the parties shall enter into an
amendment of this Agreement revising Schedule 1.2 and the Borrower shall
execute and deliver to the Agent new Notes for each Lender whose Commitment
has changed so that the maximum principal amount of such Lender's Note shall
equal its Commitment. The Agent shall promptly 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 or the effective
date of such reduction in the Total Commitment, as applicable, and shall
otherwise be in substantially the form of the replaced Notes. On the date of
issuance of any new Notes pursuant to this Section 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, substantially in the form of the relevant
portions of the opinion delivered pursuant to Section 10.6 hereof. The
surrendered Notes shall be canceled and returned to the Borrower.

     Section 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 Note 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.

     Section 2.4. Interest on Loans.

          (a) Each Base Rate Loan shall bear interest commencing with the
Borrowing Date thereof at the rate equal to the Base Rate.

          (b) Each LIBOR 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 the Applicable LIBOR
Margin per annum above the LIBOR Rate determined for such Interest Period.

          (c) The Borrower unconditionally promises, in accordance with and
subject to the provisions of the Loan Documents, to pay interest on each Loan
in arrears on each Interest Payment Date with respect thereto and, with
respect to any LIBOR Rate Loan, on the last day of the Interest Period with
respect thereto.

     Section 2.5. Requests for Loans.

          (a) 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 Days prior to the proposed Borrowing Date of
any Base Rate Loan and (b) three (3) Eurodollar Business Days prior to the
proposed Borrowing Date of any LIBOR Rate 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 statement in the form of Exhibit C
hereto signed by a Responsible Officer setting forth in reasonable detail
computations evidencing compliance with the covenants contained in Section 9.1
through Section 9.7 hereof after giving effect to such requested Loan (a
"Compliance Certificate"). On the same day as the receipt of a Loan Request
for a Base Rate Loan, and within one (1) Business Day after receipt of a Loan
Request for a LIBOR Rate Loan, 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 (if such
following day is a Business Day, and if not, before 10:30 AM Boston time on
the next succeeding Business Day), notify the Agent if it believes that any of
the conditions contained in Section 11 of this Agreement has not been met or
waived. If such a notice is given, Agent shall poll the Lenders, and the
Requisite Lenders shall promptly determine whether all of the conditions
contained in Section 11 of this Agreement have been met or waived. If no such
notice is given by any Lender or if following such notice the Requisite
Lenders determine that the conditions contained in Section 11 have been met or
waived, or, in any event, if all conditions in Section 11 have in fact been
met or waived, Agent shall notify the Lenders that 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 $1,000,000 or an integral multiple of $500,000 in excess thereof.

          (b) Notwithstanding anything contained in Section 2.5 (a) to the
contrary, in the event that the making of a requested Loan would cause
non-compliance with any of the covenants contained in Section 9.1 through
Section 9.7 hereof, the Agent may, in its sole discretion, reduce the amount
of the Loan Request to an amount which would enable the Borrower to maintain
compliance with such otherwise defaulted covenant or covenants and Borrower
shall accept the Loan made pursuant to such reduced Loan Request.

   Section 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 Rate Loan to a Base 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 Rate Loan
into a Base 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 Section 2.6(b) and Section 2.6(d)
hereof with respect to any such conversion of a Base Rate Loan to a LIBOR Rate
Loan, the Borrower shall give the Agent at least three (3) Eurodollar Business
Days prior written notice of such election and (iv) no Loan may be converted
into a LIBOR Rate Loan when any Default or Event of Default has occurred and
is continuing. The Agent shall promptly notify the Lenders of any such request
received. 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 Base Rate Loan to a LIBOR Rate Loan shall be
for an amount equal to $1,000,000 (unless the aggregate outstanding principal
amount of Loans is less than $1,000,000) or an integral multiple of $500,000
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 Section 2.6 (a) ; provided
that no LIBOR Rate 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 Base 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 Base Rate Loan at the end of the applicable Interest Period.

          (d) The Borrower may not request a LIBOR Rate Loan pursuant to
Section 2.5, elect to convert a Base Rate Loan to a LIBOR Rate Loan pursuant
to Section 2.6(a) or elect to continue a LIBOR Rate Loan pursuant to Section
2.6(b) if, after giving effect thereto, there would be greater than five (5)
LIBOR Rate Loans outstanding. Any Loan Request for a LIBOR Rate Loan that
would create greater than five (5) LIBOR Rate Loans outstanding shall be
deemed to be a Loan Request for a Base Rate Loan.

     Section 2.7. Funds for Loans.

          (a) Subject to Section 2.5 and other provisions of this Agreement,
not later than 1:00 p.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
Section 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.

          (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.

     Section 2.8. [Intentionally Omitted].

     Section 2.9. Letters of Credit.

     (a) Up to $50,000,000 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 Section 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;
provided, however, that the Agent may, in its sole discretion, at the request
of Borrower issue Letters of Credit with an initial term in excess of one (1)
year, so long as the expiry date of any such Letter of Credit is 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 face
amount of the Letter of Credit. Such reserved amounts shall remain in place
and shall be unavailable for borrowing under Section 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 D 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 face 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 accompanied by a Compliance Certificate in the form of Exhibit C hereto
signed by a Responsible Officer setting forth in reasonable detail
computations evidencing compliance with the covenants contained in Section 9
hereof after including in the Outstanding Obligations the face amount of the
requested Letter of Credit. The Agent shall also require that the Borrower
complete its standard letter of credit application, 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 Section 11 of this Agreement
has not been met or waived such that a Loan in an amount equal to the face
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 Agent
shall poll the Lenders, and the Requisite Lenders shall promptly determine
whether all of the conditions contained in Section 11 of this Agreement have
been met or waived. If no such notice is given by any Lender or if following
such notice the Requisite Lenders determine that the conditions contained in
Section 11 have been met or waived, or if in any event all conditions
contained in Section 11 have in fact been met or waived, the Agent shall
notify the Lenders, and 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 Section
2.9(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 face 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 the difference between the then prevailing Applicable
LIBOR Margin minus 12.5 basis points per annum of the face amount of the
Letter of Credit, which Letter of Credit fee shall be due and payable
quarterly in arrears on the last Business Day of each calendar quarter, 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. 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) Notwithstanding any other provisions of this Agreement, the Borrower
hereby agrees to reimburse the Agent on the Drawing Date, upon the
notification of the Agent, for any payment or disbursement made by the Agent
under any Letter of Credit. If and to the extent that any amounts are drawn
upon any Letters of Credit and are not reimbursed by the Borrower, then on the
Business Day immediately following each Drawing Date the Agent shall notify
the Lenders ofthe amount of the draft paid by the Agent on such Drawing Date,
and the payment of such draft shall constitute an advance of a Mandatory Base
Rate Loan which shall bear interest as a Base Rate Loan from the Drawing Date,
but which may be converted to a LIBOR Rate Loan in accordance with the terms
hereof; provided, however, that if there then exists a Default or Event of
Default, the payment of the draft shall be deemed a purchase by the Lenders of
the Agent's right to reimbursement under such Letter of Credit. On the first
Business Day after the delivery of the notice to Lenders referenced in the
previous sentence, each Lender shall make available to the Agent in
immediately available funds its Commitment Percentage of the amount of the
Mandatory Base 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 such first Business Day after the Drawing Date, such Lender shall pay to
the Agent on 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 Section 2.7(b). Each Lender's obligation to
fund its Commitment Percentage of Mandatory Base 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 Section 11. Unless the Borrower
has reimbursed the Agent in accordance with the first sentence of this
paragraph, then 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 reasonably 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.

     (e) The Borrower's obligations under this Section 2.9 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
(i) a voluntary termination of this Agreement in connection with an optional
prepayment of all Loans in accordance with Section 3.3 or (ii) an acceleration
of the maturity of the Loans pursuant to Section 12.1, the amounts which shall
thereupon become immediately due and payable by the Borrower shall include a
sum equal to the aggregate face amount of such then effective Letters of
Credit. Such sum shall be deposited in an interest bearing 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 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 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 reimburse the Lenders in respect of Loans made 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
enforcement proceeds under Section 12.4.



     Section 3. REPAYMENT OF THE LOANS.

     Section 3.1. Maturity. The Borrower unconditionally promises, in
accordance with, and subject to, the provisions of the Loan Documents, 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.

     Section 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.

     Section 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
Rate Loans made pursuant to this Section 3.3 may be made only on the last day
of the Interest Period relating thereto, except as set forth below in this
Section 3.3. The Borrower shall give the Agent no later than 10:00 a.m.,
Boston time, at least one (1) Business Day's prior written notice of any
prepayment pursuant to this Section 3.3 of any Base Rate Loans and three (3)
Eurodollar Business Days' notice of any proposed repayment pursuant to this
Section 3.3 of any LIBOR Rate 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 (or, if the aggregate outstanding principal amount of
Loans is less than $1,000,000, the full amount thereof) 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. Unless otherwise requested by the Borrower, the principal
payments so received shall be applied first to the principal of Base Rate
Loans and then to the principal of LIBOR Rate Loans. Notwithstanding anything
contained herein to the contrary, the Borrower may make a full or partial
prepayment of a LIBOR Rate Loan on a date other than the last day of the
Interest Period relating thereto, if all such 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) Fixed Rate Prepayment Fee. Borrower acknowledges that prepayment
or acceleration of a LIBOR Rate 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 Rate Loan in accordance with the Loan Request
therefor, as a result of Borrower's cancellation thereof, shall be treated as
if such LIBOR Rate Loan had been prepaid.) Therefore, on the date a LIBOR Rate
Loan is prepaid or the 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 ("Fixed Rate 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 Rate Loan being
prepaid. If the result is zero or a negative number, there shall be no Fixed
Rate Prepayment Fee. If the result is a positive number, then the resulting
percentage shall be multiplied by the amount of the LIBOR Rate Loan being
prepaid. 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 Fixed Rate Prepayment Fee.

          (b) Upon the written notice to Borrower from Agent, Borrower shall
immediately pay to Agent, for the account of the Lenders, the Fixed Rate
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 Rate 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 Fixed Rate
Prepayment Fee. Borrower further agrees to pay the Fixed Rate Prepayment Fee,
if any, whether or not a Lender elects to purchase, sell and/or match funds.



     Section 4. CERTAIN GENERAL PROVISIONS.

     Section 4.1. Fees. On the Effective Date, the Borrower shall pay to
Fleet National Bank, NA ("Fleet"), as Agent for the Lenders hereunder, the
fees in the amounts specified in the fee agreement among Fleet and the
Borrower dated April 10, 2000. Fleet shall be responsible for the facility
fees which it has agreed to pay to the other Lenders.

     Section 4.2. Commitment Fee. The Borrower shall pay to the Agent for
the accounts of the Lenders in accordance with their respective Commitment
Percentages a commitment fee calculated at the rates set forth below per annum
on the average daily amount by which the Total Commitment (as it may have been
reduced pursuant to Section 2.2) exceeds the Outstanding Obligations (such
excess, the "Unused Amount"):

          Unused Amount                                     Fee Rate
          -------------                                     --------

          less than 35% of Total Commitment             15 basis points

          35% or more of Total Commitment               25 basis points

The commitment 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 Section
2.2(a), the commitment 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.

     Section 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 Section
4.1, Section 4.5 and Section 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.

          (c) In the event that Borrower is obligated to pay any additional
amounts described in clause (b) above in respect of any Lender's Loan, such
Lender shall make commercially reasonable efforts to change the jurisdiction
of its lending office if, in the reasonable judgment of such Lender, doing so
would eliminate or reduce Borrower's obligation to pay such additional amounts
and would not be disadvantageous to such Lender.

     Section 4.4. Computations. All computations of interest on the Loans
and of other fees to the extent applicable shall be based on a 360-day year
and paid for the actual number of days elapsed. Except as otherwise provided
in the definition of the term "Interest Period" with respect to LIBOR Rate
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 interest shall
accrue during such extension. 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.

     Section 4.5. Additional Costs, Etc. If any change from and after the
date hereof in 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.



     Section 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.

     Section 4.7. Certificate. Each Lender shall notify the Borrower and
the Agent of any event occurring after the Effective Date entitling such
Lender to compensation under Section 4.5 or Section 4.6 as promptly as
practicable. A certificate setting forth any additional amounts payable
pursuant to Section 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.

     Section 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 or
reasonable cost or 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 Rate 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 Rate 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, and (c) the making of any payment of a LIBOR
Rate Loan or the making of any conversion of a LIBOR Rate Loan to a Base 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 Rate Loan
(including, but not limited to, any fees payable under Section 3.3(a) hereof).

     Section 4.9. Interest on Overdue Amounts. Overdue principal and (to
the extent permitted by applicable law) interest on the Loans and all other
overdue amounts payable hereunder or under any of the other Loan Documents,
including amounts owed from and after the occurrence of an Event of Default,
shall bear interest compounded monthly and payable on demand at a rate per
annum equal to four percent (4%) above the Base Rate until such amount shall
be paid in full (after as well as before judgment).

     Section 4.10. Inability to Determine LIBOR Rate. In the event, prior
to the commencement of any Interest Period relating to any LIBOR Rate 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 to be applicable to any LIBOR Rate 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 Rate Loans shall be
automatically withdrawn and shall be deemed a request for Base Rate Loans, (b)
each then outstanding LIBOR Rate Loan will automatically, on the last day of
the then current Interest Period thereof, become a Base Rate Loan, and (c) the
obligations of the Lenders to make LIBOR Rate Loans shall be suspended until
the Agent determines that the circumstances giving rise to such suspension no
longer exist, whereupon the Agent shall so notify the Borrower.

     Section 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 Rate Loans, such Lender shall forthwith give
notice of such circumstances to the Borrower and the Agent and thereupon (a)
the Commitment of such Lender to make LIBOR Rate Loans or convert Loans of
another Type to LIBOR Rate Loans shall forthwith be suspended and (b) the
LIBOR Rate Loans then outstanding shall be converted automatically to Base
Rate Loans on the last day of each Interest Period applicable to such LIBOR
Rate 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 Section 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 Rate Loans hereunder.

     Section 4.12. Replacement of Lenders. If Agent or any of the Lenders
shall make a notice or demand upon the Borrower pursuant to Section 4.3,
Section 4.5, Section 4.6, or Section 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 (which consent shall not be unreasonably withheld or
delayed). In such event the assignment shall take place as promptly as
reasonably practicable 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 Section 19.1 (and clause (d) thereof shall not be
applicable) and the assigning Lender shall receive from the Eligible Assignee
or the Borrower 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 Section 4.2 allocated to the assigning Lender,
and the replaced Lender shall be released from all of the obligations of a
Lender hereunder from and after the effective date of its replacement.

     Section 5. UNENCUMBERED ASSETS; NO LIMITATION ON RECOURSE.

     Section 5.1. Unencumbered Assets.

     (a) The Borrower represents and warrants that each of the Real Estate
Assets listed on Schedule 1.1 will on the Effective Date satisfy all of the
conditions set forth in the definition of Unencumbered Asset. The Lenders
confirm that each of the Real Estate Assets listed on Schedule 1.1 is, on the
Effective Date, accepted as an Unencumbered Asset. From time to time during
the term of this Agreement, upon the written consent of the Majority Lenders
(which consent shall not be unreasonably withheld or delayed), additional Real
Estate Assets may become Unencumbered Assets and certain Real Estate Assets
which previously satisfied the conditions set forth in the definition of
Unencumbered Asset may cease to be Unencumbered Assets by virtue of property
dispositions, creation of Liens or other reasons. There shall be attached to
each Compliance Certificate delivered pursuant to Section 7.4(d) or Section
7.13 an updated listing of the Unencumbered Assets relied upon by the Borrower
in computing the Value of All Unencumbered Assets and the Unencumbered Asset
Adjusted Net Operating Income stated in such Compliance Certificate.
Compliance Certificates delivered pursuant to Section 2.5(a) or Section 2.9(b)
may, at Borrower's option, include an updated listing of the Unencumbered
Assets and shall include such updated listing whenever a redetermination of
the Value of All Unencumbered Assets based on such an updated listing would
result in a material decrease (from that shown on the most recently delivered
Compliance Certificate) in the Value of All Unencumbered Assets by virtue of
property dispositions, creation of Liens or other reasons.

     (b) The Agent, at the written direction of the Requisite Lenders and
subject to the provisions of Section 15 hereof, may from time to time obtain
Appraisals of any Unencumbered Assets, and the Borrower and the Guarantors
shall cooperate fully with the appraiser selected by the Agent to conduct such
Appraisals. In the event that the Borrower obtains an appraisal of one or more
of the Unencumbered Assets other than pursuant to this subsection, the
Borrower shall at its expense deliver a copy of such appraisal to the Agent
promptly upon the completion thereof, and the Agent may elect, in its sole
discretion and subject to applicable laws, to treat such appraisal as an
"Appraisal."

     Section 5.2. Waivers by Requisite Lenders.

     (i) If any Real Estate Asset fails to satisfy any of the requirements
contained in the definition of Unencumbered Asset then the applicable Real
Estate Asset may nevertheless be deemed to be an Unencumbered Asset hereunder
if the Requisite Lenders vote to accept such Real Estate Asset as an
Unencumbered Asset.

     (ii) Notwithstanding the foregoing, Borrower, upon prior written request
to the Agent, shall be permitted a six month waiver without the consent of the
Requisite Lenders of the Occupancy Rate requirements of the definition of
"Unencumbered Asset" for a particular Unencumbered Asset under the following
conditions:

          (A) there shall be a termination or expiration of any Lease(s) in a
     particular Real Estate Asset resulting in occupancy below 70% but greater
     than 50%,

          (B) during six (6) months from the date of such expiration(s) or
     termination(s) Borrower is diligently attempting to re-establish an
     Occupancy Rate of at least 70%,

          (C) the Value of All Unencumbered Assets is at least $650 Million at
     the time of the waiver request, and

          (D) Unencumbered Assets with an aggregate Unencumbered Asset Value
     no larger than the greater of (1) that of the Unencumbered Asset for
     which the Borrower seeks the waiver or (2) 10% of the Value of All
     Unencumbered Assets, shall fail to meet the Occupancy Rate requirements
     of the definition of "Unencumbered Asset."

     Section 5.3. Rejection of Unencumbered Assets. If at any time the Agent
determines that any Real Estate Asset listed as an Unencumbered Asset by the
Borrower does not satisfy all of the requirements of the definition of
Unencumbered Asset (to the extent not waived by the Requisite Lenders pursuant
to Section 5.2(i) or by the Agent pursuant to Section 5.2(ii)) it may reject
an Unencumbered Asset by notice to the Borrower and if the Agent so requests
the Borrower shall revise the applicable Compliance Certificate to reflect the
resulting change in the Value of All Unencumbered Assets and the Unencumbered
Asset Adjusted Net Operating Income.

     Section 5.4. Change in Circumstances. (i) If at any time during the term
of this Agreement Borrower becomes aware that any of the representations
contained in Section 6 are no longer accurate with respect to any Unencumbered
Asset, it will promptly so notify the Agent and either request a waiver
pursuant to Section 5.2 or confirm that such Real Estate Asset is no longer an
Unencumbered Asset. If any waiver so requested is not granted by the Requisite
Lenders or the Agent, as applicable, within ten (10) Business Days the Agent
shall reject the applicable Unencumbered Asset pursuant to Section 5.3.

     (ii) Notwithstanding the foregoing or anything else in this Agreement to
the contrary, for so long from and after the Effective Date that the
Unencumbered Asset Value of the Unencumbered Asset identified on Schedule 1.1
hereto as 1372 Broadway, New York, New York ("1372 Broadway") is equal to or
in excess of twenty percent (20%) of the Value of All Unencumbered Assets, the
Borrower may not withdraw or obtain the release of 1372 Broadway as an
Unencumbered Asset for the purposes of this Agreement and the Loans (including
all covenant calculations hereunder) without the written consent of the
Majority Lenders. Notwithstanding the foregoing, from and after the first date
that the Unencumbered Asset Value of 1372 Broadway is less than twenty percent
(20%) of the Value of All Unencumbered Assets, the Borrower may withdraw or
obtain the release of 1372 Broadway as an Unencumbered Asset for the purposes
of this Agreement and the Loans without the written consent of the Majority
Lenders, upon which withdrawal or release the first sentence of this
subsection (ii) shall be of no further force or effect.

     Section 5.5. No Limitation on Recourse.The Obligations are full recourse
obligations of the Borrower and, to the extent provided in this Agreement, of
the Guarantors, and all of their respective Real Estate Assets and other
properties shall be available for the indefeasible payment in full in cash and
performance of the Obligations.

     Section 5.6. Additional Guarantor Subsidiaries. If Borrower desires that
a Real Estate Asset owned by a Related Company which is not previously a
Guarantor become an Unencumbered Asset, then provided that the applicable
Related Company is a direct or indirect Subsidiary of Borrower or any
Guarantor, such Related Company may become a Guarantor upon delivery to the
Agent of the following, all in form and substance reasonably satisfactory to
the Agent: (a) a supplement to this Agreement executed and delivered by the
such proposed Guarantor assenting to be bound by all the terms of the Loan
Documents as a Guarantor, and (b) good standing certificates, general partner

Related Companies, exceeds in the aggregate $5,000,000.00;

          (k) if any of the Loan Documents or any material provision of any

express prior written agreement, consent or approval of the Agent, or any
action at law, suit or in equity or other legal proceeding to make
unenforceable, cancel, revoke or rescind any of the Loan Documents shall be

          (l) one or more ERISA Events occurs which individually or in the

          (m) the Borrower or any Guarantor shall be indicted for a federal
crime, a punishment for which could include the forfeiture of any assets of
the Borrower;

          (n) the Borrower shall fail to pay, observe or perform any term,

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
Sections 12.1(h) or 12.1(i), all such amounts shall become immediately
due and payable automatically and without any requirement of notice from the
Agent or action by the Requisite Lenders.

     Section 12.2. Termination of Commitments. If any one or more Events of
Default specified in Section 12.1(h) or Section 12.1(i) shall occur, any
unused portion of the Commitments hereunder shall forthwith terminate and the
Lenders shall be relieved of all obligations to make Loans to the Borrower or
to issue Letters of Credit for the benefit of the Borrower. If any other Event
of Default shall have occurred and be continuing, the Agent, at the direction
of the Majority Lenders, may by notice to the Borrower terminate the unused
portion of the Commitments hereunder and upon such notice being given such
unused portion of the Commitments hereunder shall terminate immediately and
the Lenders shall be relieved of all further obligations to make Loans other
than Mandatory Base Rate Loans. No termination of the Commitments hereunder
shall relieve the Borrower of any of the Obligations or any of its existing
obligations to any Lender arising under other agreements or instruments.

     Section 12.3. Remedies. In case any one or more of the Events of Default
shall have occurred, and whether or not the Requisite Lenders shall have
accelerated the maturity of the Loans pursuant to Section 12.1, each Lender,
if owed any amount with respect to the Loans, may, with the consent of the
Requisite 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 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.

     Section 12.4. Distribution of Enforcement Proceeds. In the event that,
following the occurrence or during the continuance of any Default or Event of
Default, the Agent or any Lender as the case may be, receives any monies in
connection with the enforcement of any of the Loan Documents, 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 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 Requisite 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;

          (c) Third, upon payment and satisfaction in full or other provisions
for payment in full satisfactory to the Requisite Lenders and the Agent of all
of the Obligations, and the deposit in any cash collateral account established
pursuant to Section 2.9(f) of the amount required thereby, to the payment of
any obligations required to be paid pursuant to Section 9-504(1)(c) of the
Uniform Commercial Code of the State of New York; and

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



     Section 13. SETOFF. During the continuance of any Event of Default, any
deposits (general or specific, time or demand, provisional or final,
regardless of currency, maturity, or the branch of where such deposits are
held) or other sums credited by or due from any of the Lenders to the
Borrower, the Company or any of the other Guarantors and any securities or
other property of the Borrower, the Company or any of the other Guarantors in
the possession of such Lender may be applied to or set off against the payment
of Obligations and any and all other liabilities, direct, or indirect,
absolute or contingent, due or to become due, now existing or hereafter
arising, of the Borrower to such Lender. 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, the Company or any of the other Guarantors 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, the Company or any of the other
Guarantors, 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, the Company or any of
the other Guarantors 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
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.



     Section 14. THE AGENT.

     Section 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.

     Section 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
such Persons shall be paid by the Borrower.

     Section 14.3. No Liability to Lenders. 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 to any
Lender 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,
shall be liable for losses due to its willful misconduct or gross negligence.

     Section 14.4. No Representations. The Agent shall not be responsible for
the execution or validity or enforceability 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 Guarantor or any holder of any of the
Notes shall 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, the
Company or any of the other Guarantors. 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. Each Lender
has been independently represented by separate counsel on all matters
regarding this Agreement.

     Section 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 shall constitute a payment
to such Lender subject to the pro rata rights to repayment based upon the
Commitment Percentage of each Lender. Neither the Borrower nor any Guarantor
shall have any obligation to see to the proper application by Agent of any
amounts paid by any of them to the Agent for the account of the Lenders. 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.
Notwithstanding the foregoing, the amounts advanced by the Additional
Commitment Lenders on the Commitment Increase Date and certain Fixed Rate
Prepayment Fees and Letter of Credit fees shall be distributed on a non pro
rata basis as provided in Section 2.2(b) and the commitment fees for the
quarter which included the Commitment Increase Date shall be paid as provided
in Section 4.2.

     (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 Section 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 Section 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 under
the Loan Documents, 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 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.

     (d) If any amount which the Agent is required to distribute to the
Lenders pursuant to this Section 14.5 is actually distributed to any Lender on
a date which is later than the first Business Day following the Agent's
receipt of the corresponding payment from the Borrower, the Agent shall pay to
such Lender 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
late distribution to such Lender, times (iii) a fraction, the numerator of
which is the number of days or portion thereof that elapsed from and including
the second Business Day after the Agent's receipt of such corresponding
payment from the Borrower to the date on which the amount so required to be
distributed to such Lender actually is distributed, and the denominator of
which is 365.

     Section 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.

     Section 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 and the Guarantors as required by Section 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.

     Section 14.8. Agent as Lender. In its individual capacity, Fleet National
Bank, NA 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.

     Section 14.9. Resignation. The Agent may resign at any time by giving
sixty (60) days, prior written notice thereof to the Lenders and the Borrower;
provided, however, that unless an Event of Default has occurred and is
continuing, Fleet National Bank, NA may not voluntary resign as Agent under
the provisions of this Agreement without the Borrower's consent. Upon any such
resignation, the Requisite 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 Requisite Lenders and shall have accepted such appointment
within thirty (30) days after the giving of notice of resignation or removal
or if the Borrower (to the extent it has approval rights with respect to the
successor Agent) 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 as Agent 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, provided that if such Letters of Credit cannot be
replaced, the successor Agent shall issue back-to-back Letters of Credit to
the retiring Agent in respect of the retiring Agent's outstanding Letters of
Credit. 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.

     Section 14.10. Notification of Defaults and Events of Default and other
Notices. 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 Section
14.10, or upon it otherwise learning of the existence of a Default or an Event
of Default, it shall promptly notify the other Lenders of the existence of
such Default or Event of Default. The Agent shall also promptly provide each
Lender with a copy of any notices which the Agent receives from the Borrower
pursuant to Section 7.5 or Section 7.13.

     Section 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 may, with the
consent of the Requisite Lenders (which consents may be obtained orally in
emergency situations), and the Agent shall, if (a) so requested by the
Requisite 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 Loan
Documents and exercise all or any such other legal and equitable and other
rights or remedies as it may have. The Requisite Lenders may direct the Agent
in writing as to the method and the extent of any such enforcement actions,
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.

     Section 14.12. Mandatory Resignation of Agent. The Agent shall be
obligated to resign in accordance with, and subject to, the provisions of
Section 14.9, without the consent of the Borrower , upon the written request
of Lenders whose aggregate Commitments constitute at least sixty-six percent
(66%) of the Total Commitment excluding the Commitment of the Lender which is
then the Agent hereunder, provided such request is made for cause, and
provided further that the successor Agent (a) is at least a managing agent
with respect to this Agreement, and (b) actively administers credits of
similar size and complexity to this Agreement and the Loans.

     Section 14.13. Matters as to Borrower. (a) Except as expressly set forth
in this Agreement, Borrower shall have no obligation to cause Agent or any of
the Lenders to perform their respective obligations under this Agreement.

     (b) Notwithstanding that a matter in question requires the consent,
approval or direction of any or all of the Lenders, Borrower may rely
exclusively on the written notice of Agent that such consent, approval, or

     Section 18. GUARANTY.

     Section 18.1. Guaranty. Subject to Section 18.7 below, each of the
Guarantors hereby, jointly and severally, unconditionally guarantees to each
Lender and the Agent the prompt payment of the Guaranteed Obligations in full
when due (whether at stated maturity, as a mandatory prepayment, by
acceleration or otherwise) (the "Guaranty"). The Guarantors additionally,
jointly and severally, unconditionally guarantee to each Lender and the Agent
the timely performance of all other obligations of the Borrower under the Loan
Documents. This Guaranty is a guaranty of payment and not of collection and is
a continuing guaranty and shall apply to Guaranteed Obligations whenever
arising.

     Section 18.2. Obligations Unconditional. The obligations of the
Guarantors hereunder are absolute and unconditional, irrespective of the
value, genuineness, validity, regularity or enforceability of any of the
Guaranteed Obligations or any of the Loan Documents, or any other agreement or
instrument referred to therein, to the fullest extent permitted by applicable
law, irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor.
Each Guarantor agrees that this Guaranty may be enforced by the Agent, on
behalf of the Lenders, without necessity at any time of resorting to or
exhausting any other security or collateral and without the necessity at any
time of having recourse to the Notes, any other of the Loan Documents or any
collateral, if any, hereafter securing the Guaranteed Obligations or
otherwise, and each Guarantor hereby waives the right to require the Lenders
to proceed against the Borrower or any other Person (including a co-guarantor)
or to require the Lenders to pursue any other remedy or enforce any other
right. Each Guarantor further agrees that it shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other Guarantor of the Guaranteed Obligations for amounts paid under this
Guaranty until such time as the Lenders have been paid in full, all
Commitments under this Agreement have been terminated, and no Person or
governmental authority shall have any right to request any return or
reimbursement of funds from the Lenders in connection with monies received
under the Loan Documents. Each Guarantor further agrees that nothing contained
herein shall prevent the the Agent or the Lenders from suing on the Notes or
any of the other Loan Documents or foreclosing their security interest in or
Lien on any collateral, if any, securing Guaranteed Obligations or from
exercising any other rights available to them under this Agreement, the Notes,
any other of the Loan Documents, or any other instrument of security, if any,
and the exercise of any of the aforesaid rights and the completion of any
foreclosure proceedings shall not constitute a discharge of any Guarantor's
obligations hereunder; it being the purpose and intent of each Guarantor that
its obligations hereunder shall be absolute, independent and unconditional
under any and all circumstances. Neither any Guarantor's obligations under
this Guaranty nor any remedy for the enforcement thereof shall be impaired,
modified, changed or released in any manner whatsoever by an impairment,
modification, change, release or limitation of the liability of the Borrower
or by reason of the bankruptcy or insolvency of the Borrower. Each Guarantor
waives any and all notice of the creation, renewal, extension or accrual of
any of the Guaranteed Obligations and notice of or proof of reliance of by,
the Agent or any Lender upon this Guaranty or acceptance of this Guaranty. The
Guaranteed Obligations, and any of them, shall conclusively be deemed to have
been created, contracted or incurred, or renewed, extended, amended or waived,
in reliance upon this Guaranty. All dealings between the Borrowers and any of
the Guarantors, on the one hand, and the Agent and the Lenders, on the other
hand, likewise shall be conclusively presumed to have been had or consummated
in reliance upon this Guaranty.

     Section 18.3. Modifications. Each Guarantor agrees that (a) all or any
part of the security now or hereafter held for the Guaranteed Obligations, if
any, may be exchanged, compromised or surrendered from time to time; (b) the
Lenders shall not have any obligation to protect, perfect, secure or insure
any such security interests, Liens or encumbrances now or hereafter held, if
any, for the Guaranteed Obligations or the properties subject thereto; (c) the
time or place of payment of the Guaranteed Obligations may be changed or
extended, in whole or in part, to a time certain or otherwise, and may be
renewed or accelerated, in whole or in part; (d) the Borrower and any other
party liable for payment under the Loan Documents may be granted indulgences
generally; (e) any of the provisions of the Notes or any of the other Loan
Documents may be modified, amended or waived; (f) any party (including any
co-guarantor) liable for the payment thereof may be granted indulgences or be
released; and (g) any deposit balance for the credit of the Borrower or any
other party liable for the payment of the Guaranteed Obligations or liable
upon any security therefor may be released, in whole or in part, at, before or
after the stated, extended or accelerated maturity of the Guaranteed
Obligations, all without notice to or further assent by such Guarantor, which
shall remain bound thereon, notwithstanding any such exchange, compromise,
surrender, extension, renewal, acceleration, modification, indulgence or
release. Each Guarantor hereby appoints the Borrower as its agent to execute
and deliver any amendments to or modifications or waivers of the Loan
Documents, and the Agent and the Lenders may rely on such appointment until
such time as a Guarantor advises the Agent and the Lenders in writing that the
Borrower is no longer authorized to so act as its agent.

     Section 18.4. Waiver of Rights. Each Guarantor expressly waives to the
fullest extent permitted by applicable law: (a) notice of acceptance of this
Guaranty by the Lenders and of all extensions of credit to the Borrower by the
Lenders; (b) presentment and demand for payment or performance of any of the
Guaranteed Obligations; (c) protest and notice of dishonor or of default
(except as specifically required in this Agreement) with respect to the
Guaranteed Obligations or with respect to any security therefor: (d) notice of
the Lenders obtaining, amending, substituting for, releasing, waiving or
modifying any security interest, Lien or encumbrance, if any, hereafter
securing the Guaranteed Obligations, or the Lenders' subordinating,
compromising, discharging or releasing such security interests, Liens or
encumbrances, if any; (e) all other notices to which such Guarantor might
otherwise be entitled; and (f) demand for payment under this Guaranty.

     Section 18.5. Reinstatement. The obligations of the Guarantors under this
Section 18 shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Person in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy or reorganization or otherwise, and each Guarantor agrees that it
will indemnify the Agent and each Lender on demand for all reasonable costs
and expenses (including, without limitation, reasonable fees of counsel)
incurred by the Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending
against any claim alleging that such payment constituted a preference,
fraudulent transfer or similar payment under any bankruptcy, insolvency or
similar law.

     Section 18.6. Remedies. The Guarantors agree that, as between the
Guarantors, on the one hand, and the Agent and the Lenders, on the other hand,
the Guaranteed Obligations may be declared to be forthwith due and payable as
provided in Section 12 hereof (and shall be deemed to have become
automatically due and payable in the circumstances provided in Section 12
hereof) notwithstanding any stay, injunction or other prohibition preventing
such declaration (or preventing such Guaranteed Obligations from becoming
automatically due and payable) as against any other Person and that, in the
event of such declaration (or such Guaranteed Obligations being deemed to have
become automatically due and payable), such Guaranteed Obligations (whether or
not due and payable by any other Person) shall forthwith become due and
payable by the Guarantors.

     Section 18.7. Limitation of Guaranty. Notwithstanding any provision to
the contrary contained herein or in any of the other Loan Documents, to the
extent the obligations of any Guarantor shall be adjudicated to be invalid or
unenforceable for any reason (including, without limitation, because of any
applicable state or federal law relating to fraudulent conveyances or
transfers), then the obligations of such Guarantor hereunder shall be limited
to the maximum amount that is permissible under applicable law (whether
federal or state and including, without limitation, the Bankruptcy Code).

     Section 18.8. Release of Guaranty. Upon consummation of the sale,
conveyance, pledge or other transfer of all of the stock or other evidence of
beneficial or legal ownership, or a sale, mortgage or pledge of all or
substantially all of the assets, of any Guarantor other than the Company, so
long as no Default or Event of Default shall have occurred and be continuing,
the Guaranty of such Guarantor, and all of its obligations and liabilities
under the Loan Documents, shall be, and shall be deemed to be, released and
discharged, and upon the request of such released Guarantor, the Agent shall
acknowledge such release in writing.

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 performance or observance by the Borrower and the
Guarantors of any terms of this Agreement or such other instrument or the
continuance of any Default or Event of Default may be waived (either generally
or in a particular instance and either retroactively or prospectively) with,
but only with, the written consent of the 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.
Notwithstanding the foregoing, (i) the rate of interest on, and the term or
amount of, the Notes or the date of any payment due hereunder or thereunder,
(ii) the amount of the Commitments of the Lenders (other than changes in
Commitments pursuant to Assignments under Section 19 or pursuant to changes in
the Total Commitment under Section 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 (including this
Section 26), (v) the funding provisions of Section 2.5 and Section 2.7 hereof,
(vi) the rights, duties and obligations of the Agent specified in Section 14
hereof, and (vii) the definitions of Majority Lenders or Requisite Lenders,
may not be amended or compliance therewith waived without the written consent
of each Lender affected thereby, nor may the Agent release the Borrower or any
Guarantor from its liability with respect to the Obligations (other than
pursuant to Section 18.8), without first obtaining the written consent of all
the Lenders. Unless otherwise directed by the Agent, any request for amendment
or waiver shall be made on no less than ten (10) Business Days notice to the
Lenders. Unless otherwise directed by the Agent, the failure of a Lender to
respond to a request for waiver or amendment shall be deemed to constitute
such Lender's consent to such waiver or amendment requested (unless such
waiver or amendment requires the consent of all 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.



     Section 27. 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.

     Section 28. ACKNOWLEDGMENTS. Each of the Borrower and the Guarantors
hereby acknowledges that: (i) neither the Agent nor any Lender has any
fiduciary relationship with, or fiduciary duty to, the Borrower and the
Guarantors arising out of or in connection with this Agreement or any of the
other Loan Documents; (ii) the relationship in connection herewith between the
Agent and the Lenders, on the one hand, and the Borrower and each Guarantor,
on the other hand, is solely that of debtor and creditor and (iii) no joint
venture or partnership among any of the parties hereto is created hereby or by
the other Loan Documents, or otherwise exists by virtue of the Facility or the
Loans.
