    Dear

      terms and conditions of Chancellor’s and the Gryphon Subsidiaries’ termination
      of employment (“Employment”) with you.

    

    In
      consideration of your agreements made as provided herein, Chancellor and the
      Gryphon Subsidiaries, jointly and severally, agree to and shall indemnify you
      and hold you harmless if you are a party to or threatened to be made a party
      to
      or otherwise involved in any threatened, pending or completed action, suit
      or
      proceeding, against the Company or the Gryphon Subsidiaries, whether of a civil,
      criminal or administrative or investigative nature, (other than an action or
      proceeding by or in the name of the Company to procure a judgment in its favor),
      against all expenses, judgments, fines, and penalties actually and reasonably
      incurred (or which would be incurred but for this indemnity and hold harmless
      obligation) by you in connection with the defense or settlement of such action
      or proceeding, to the fullest extent permitted by Nevada law; provided that
      any
      settlement be approved in writing by the Company.

    

    Further,
      Chancellor, the Gryphon Subsidiaries and the undersigned directors and
      shareholders of Chancellor, as releasors (the “Chancellor Releasors”), remise,
      release and forever discharge you, your respective, agents, representatives,
      heirs, successors and assigns, jointly and severally, from any and all debts,
      demands, actions, causes of action, suits, damages, claims and liabilities
      based
      on matters relating to your Employment or any other matter of whatever kind
      or
      nature, known or unknown, suspected or unsuspected, accrued or unaccrued,
      whether in law, equity or otherwise, and whether under contract, warranty,
      tort
      or otherwise, which the Chancellor Releasors ever had, now have or may have,
      claim or assert from the beginning of the world to the date of this Separation
      and Release Agreement, excepting for your obligations under this Separation
      and
      Release Agreement. 

    

    Chancellor’s,
      its directors’ and shareholders’ and Gryphon Subsidiaries’ agreements to provide
      you with the indemnification and releases outlined above is conditioned upon
      your agreement to the following: 

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    First,
      In
      consideration for settlement of the termination of your employment as provided
      hereinabove and the agreements of the Chancellor Releasors made as provided
      herein, you waive any rights to any salary or unreimbursed expenses owed to
      you

      and forever discharge the Chancellor Releasors, their respective officers,
      directors, agents, representatives, counsel, successors and assigns, jointly
      and
      severally, from any and all debts, demands, actions, causes of action, suits,
      damages, claims and liabilities based on matters relating to your Employment
      or
      any other matter of whatever kind or nature, known or unknown, suspected or
      unsuspected, accrued or unaccrued, whether in law, equity or otherwise, and
      whether under contract, warranty, tort or otherwise, which you ever had, now

      and
      the Gryphon Subsidiaries. 

    

    Third,

2. AGREEMENT TO MAKE LOANS.

2.1 Agreement to Make Revolving Loan. Subject to the terms and conditions of
this Agreement and relying upon the representations and warranties contained in
this Agreement and the other Loan Documents, each of the Lenders agree to lend
to the Borrower up to a maximum aggregate principal amount equal to such
Lender's Commitment and the Borrower may borrow, repay and reborrow from time to
time between the Closing Date and the Termination Date such sums as are
requested by Borrower up to a maximum aggregate principal amount at any one time
equal to the Loan Amount; however, any Advances of proceeds of the Loan shall be
made by the Lenders pro rata, in accordance with each Lender's Commitment
Percentage. Each request for an Advance of the Loan hereunder shall constitute a
representation and warranty by the Borrower that the conditions set forth in
ss.ss.7 and 8 have been satisfied on the date of such request unless, and only
to the extent that, any such representation and warranty relates specifically
and only to an earlier date in time.

2.3 Purpose of Loan. The Loan shall be used by the Borrower for the following
purposes: property acquisitions, Acquisitions, renovations, expansions, tenant
improvement costs, equity and/or debt investments associated with Syndication
REITS, for general corporate purposes, and to pay the costs and expenses
incidental to closing the Loan.

2.4 Requests for Advances. (a) The Borrower shall give to the Agent written
notice in the form of Schedule 3 hereto (or telephonic notice confirmed in
writing in the form of Schedule 3 hereto) of each Advance requested hereunder (a
"Loan Request") in accordance with the interest rate selection requirements set
forth in Section 2.5.3. Each such Loan Request shall specify (i) the principal
amount of the Advance requested, (ii) the intended use of the proceeds of such
Advance; and (iii) the proposed Drawdown Date of such Advance. The Borrower
agrees to accept the Advance requested from the Agent on the proposed Drawdown
Date. Each Advance shall be a minimum aggregate amount of $1,000,000.00 or an
integral multiple of $100,000 in excess thereof.

      (b) In the event that the Borrower shall receive Advance(s) in excess of
the Loan Amount (and, if applicable, exclusive of the Overline Facility) the
Borrower shall immediately repay the Loan by an amount sufficient to reduce the
outstanding principal balance to equal or less than the Loan Amount.

      (c) The Agent and the Lenders may rely on any request for an Advance or
financial accommodation which the Agent and the Lenders, reasonably and in good
faith, believes to have been made by a person duly authorized to act on behalf
of the Borrower and may decline to make any such requested Advance or to provide
any such financial accommodation pending the Agent and the Lenders' being
furnished with such documentation concerning that person's authority to act as
may be satisfactory to the Agent and the Lenders.

                                      -3-
<PAGE>

      (d) A request by the Borrower for any Advance or of the issuance of an L/C
shall be irrevocable and shall constitute certification by the Borrower that as
of the date of such request, each of the following is true and correct:

            (i)   There has been no material adverse change in the Borrower's
                  financial condition from the most recent financial information
                  furnished the Lenders pursuant to this Agreement;

            (ii)  The Borrower is in compliance with, and has not breached any
                  of, its covenants contained in this Agreement;

            (iii) Each representation which is made herein or in any of the Loan
                  Documents is then true and complete as of and as if made on
                  the date of such request unless such representation relates
                  specifically and only to an earlier date in time; and

            (iv)  No event has occurred nor failed to occur which occurrence or
                  failure is, or with the passage of time or giving of notice
                  (or both) would constitute an Event of Default (as described
                  herein), whether or not the Agent and the Lenders has
                  exercised any of its rights upon such occurrence or failure.

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

      (f)   (i)   The Borrower may request that the Issuing Lender issue
                  L/C's for the account of the Borrower subject to and in
                  accordance with ss.ss.2.8, 2.9 and 2.10 of this Agreement and
                  the other provisions of this clause (f). Each such request
                  shall be in such manner as may from time to time be acceptable
                  to the Issuing Lender, in writing.

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

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

                                      -4-
<PAGE>

      (g) The Lenders, without the request of the Borrower, may make an Advance
equal to the amount which the Borrower is obligated to pay to the Issuing Lender
or for which the Borrower or the Issuing Lender becomes obligated on account of,
or in respect to, any L/C. Such Advance shall be made and even if such Advance
would result in Loan Amount being exceeded. Such action on the part of the
Lenders shall not constitute a waiver of the Lenders' rights under Section
2.4(b) above.

2.5 Interest Rate and Payment Terms. The Loan shall be payable as to interest
and principal in accordance with the provisions of this Agreement and the Note.
This Agreement also provides for interest at a Default Rate, Late Charges and
prepayment rights and fees. All payments for the account of Lenders shall be
applied to the respective accounts of the Lenders in accordance with each
Lender's Commitment Percentage of the Loan. The Agent will disburse such
payments to the Lenders on the date of receipt thereof if received prior to
10:00 a.m. on such date and, if not, on the next Business Day. Any and all
interest rate selection and conversion provisions in this Agreement are to be
administered by the Agent and to be allocated on a pro rata basis to the Note
held by each Lender based upon such Lender's Commitment Percentage.

            2.5.1 Borrower's Options. Principal amounts outstanding under the
      Loan shall bear interest at the following rates, at Borrower's selection,
      subject to the conditions and limitations provided for in this Agreement:
      (i) Variable Rate or (ii) Adjusted Libor Rate.

            2.5.2 Selection To Be Made. Borrower shall select and thereafter may
      change the selection of, the applicable interest rate, from the
      alternatives otherwise provided for in this Agreement, by giving Agent a
      Notice of Rate Selection: (i) prior to the Loan, (ii) prior to the end of
      each Interest Period applicable to a Libor Advance, or (iii) on any
      Business Day on which Borrower desires to convert an outstanding Variable
      Rate Advance to a Libor Advance.

            2.5.3 Notice. A "Notice of Rate Selection" shall be a written
      notice, given by cable, tested telex, telecopier (with authorized
      signature), or by telephone if immediately confirmed by such a written
      notice, from an authorized representative of Borrower which: (i) is
      irrevocable; (ii) is received by Agent not later than 10:00 o'clock A.M.
      Eastern Time: (a) if an Adjusted Libor Rate is selected, at least three
      (3) Business Days but not more than five (5) Business Days prior to the
      requested Drawdown Date or the end of the current Interest Period to which
      such selection is to apply or (b) if a Variable Rate is selected, on the
      day on which such Loan is funded; (iii) as to each selected interest rate
      option, sets forth the aggregate principal amount(s) to which such
      interest rate option(s) shall apply and the Interest Period(s) applicable
      to each Libor Advance; provided, however, that no portion of the
      outstanding principal amount of any LIBOR Advances may be converted to, or
      continued as, LIBOR Advances when any Event of Default has occurred and is
      continuing, and no portion of the outstanding principal amount of any
      LIBOR Advances may be converted to LIBOR Advances of a different duration
      if such LIBOR Advances relate to any Hedging Obligations. In the absence

                                      -5-
<PAGE>

      of delivery of a continuation/conversion notice with respect to any LIBOR
      Advances at least three Business Days before the last day of the then
      current Interest Period with respect thereto, such LIBOR Rate Loan shall,
      on such last day, automatically convert to a loan that accrues interest by
      reference to the LIBOR Rate Loans for a thirty (30) day period.

            2.5.4 Intentionally Deleted.

            2.5.5 Telephonic Notice. Without any way limiting Borrower's
      obligation to confirm in writing any telephonic notice, Agent may act
      without liability upon the basis of telephonic notice believed by Agent in
      good faith to be from Borrower prior to receipt of written confirmation.
      In each case Borrower hereby waives the right to dispute Agent's record of
      the terms of such telephonic Notice of Rate Selection in the absence of
      manifest error.

            2.5.6 Limits On Options. One Selection Per Month. Each Libor Advance
      shall be in a minimum amount of $1,000,000. At no time shall there be
      outstanding a total of more than five (5) Libor Advances combined at any
      time. If Borrower shall make more than one (1) Libor Rate Loan interest
      rate selection in any thirty (30) day period, excluding conversions of
      outstanding advances made at the end of an applicable Interest Period of
      any previously outstanding Libor Advance, Agent may impose and Borrower
      shall pay a reasonable processing fee for each such additional selection.
      This limitation on interest rate selection shall not limit the number of
      Advances which may be requested by the Borrower in any thirty (30) day
      period.

            2.5.7 Payment and Calculation of Interest. All interest shall be:
      (a) Payable in arrears commencing November 1, 2007 and on the same day of
      each month thereafter until the principal together with all interest and
      other charges payable with respect to the Loan shall be fully paid; and
      (b) calculated on the basis of a 360 day year and the actual number of
      days elapsed. Each change in the Prime Rate shall simultaneously change
      the Variable Rate payable under this Agreement. Interest at the Adjusted
      Libor Rate shall be computed from and including the first day of the
      applicable Interest Period to, but excluding, the last day thereof.

            2.5.8 Principal. The entire principal balance shall be due and
      payable in full at the Termination Date.

            2.5.9 Prepayment. The Loan or any portion thereof may be prepaid in
      full or in part at any time upon three (3) Business Days, prior written
      notice to Agent without premium or penalty with respect to Variable Rate
      Advances and, with respect to Libor Advances subject to a Make-Whole
      Provision and upon payment of a LIBOR Rate Loan Prepayment Fee. Any
      partial prepayment of principal shall first be applied to any principal
      amount outstanding under the Overline Facility and otherwise in accordance
      with the terms hereof.

                                      -6-
<PAGE>

            2.5.10 Maturity. On the Maturity Date all accrued interest,
      principal and other charges due with respect to the Loan shall be due and
      payable in full and the principal balance and such other charges, but not
      unpaid interest, shall continue to bear interest at the Default Rate until
      so paid.

            2.5.11 Method of Payment; Date of Credit. All payments of interest,
      principal and fees shall be made in lawful money of the United States in
      immediately available funds, without counterclaim or set off and free and
      clear, and without any deduction or withholding for, any taxes or other
      payments (a) by direct charge to an account of Borrower maintained with
      Agent (or the then holder of the Loan), or (b) by wire transfer to Agent
      or (c) to such other bank or address as the Agent may designate in a
      written notice to Borrower. Payments shall be credited on the Business Day
      on which immediately available funds are received prior to 10:00 o'clock
      A.M. Eastern Time; payments received after ten o'clock A.M. Eastern Time
      shall be credited to the Loan on the next Business Day, payments which are
      by check, which Agent may at its option accept or reject, or which are not
      in the form of immediately available funds shall not be credited to the
      Loan until such funds become immediately available to Agent, and, with
      respect to payments by check, such credit shall be provisional until the
      item is finally paid by the payer bank.

            2.5.12 Billings. Agent may submit monthly billings reflecting
      payments due; however, any changes in the interest rate which occur
      between the date of billing and the due date may be reflected in the
      billing for a subsequent month. Neither the failure of Agent to submit a
      billing nor any error in any such billing shall excuse Borrower from the
      obligation to make full payment of all Borrower's payment obligations when
      due.

            2.5.13 Default Rate. Agent shall have the option of imposing, and
      Borrower shall pay upon billing therefor, an interest rate which is four
      percent (4%) per annum above the Variable Rate ("Default Rate"): (a)
      following any Event of Default, unless and until the Event of Default is
      cured or waived by Agent; and (b) after the Maturity Date. Borrower's
      right to select pricing options shall cease upon the occurrence and during
      the continuance of an Event of Default.

            2.5.14 Late Charges. Borrower shall pay, upon billing therefor, a
      "Late Charge" equal to five percent (5%) of the amount of any payment of
      principal, other than principal due at Maturity, interest, or both, which
      is not paid within ten (10) days of the due date thereof. Late charges
      are: (a) payable in addition to, and not in limitation of, the Default
      Rate, (b) intended to compensate Agent and the Lenders for administrative
      and processing costs incident to late payments, (c) are not interest, and
      (d) shall not be subject to refund or rebate or credited against any other
      amount due.

      maybe prepaid upon the terms and conditions set forth herein. For LIBOR
      Advances in connection with which the Borrower has or may incur Hedging
      Obligations, additional obligations may be associated with prepayment, in
      accordance with the terms and conditions of the applicable Hedging
      Contracts. The Borrower shall give the Agent, no later than 10:00 a.m.,
      New York City time, at least three (3) Business Days notice of any
      proposed prepayment of any LIBOR Advances, specifying the proposed date of
      payment of such LIBOR Advances, and the principal amount to be paid. Each
      partial prepayment of the principal amount of LIBOR Advances shall be in
      an integral multiple of $100,000.00 and accompanied by the payment of all
      charges outstanding on such LIBOR Advances and of all accrued interest on
      the principal repaid to the date of payment. Borrower acknowledges that
      prepayment or acceleration of a LIBOR Advance during an Interest Period
      shall result in the Lender 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.
      Therefore, all full or partial prepayments of LIBOR Advances shall be
      accompanied by, and the Borrower hereby promises to pay, on each date a
      LIBOR Advance is prepaid or the date all sums payable hereunder become due
      and payable prior to their stated maturity, by acceleration or otherwise,
      in addition to all other sums then owing, an amount ("LIBOR Rate Loan
      Prepayment Fee") determined by the Agent pursuant to the following
      formula:

      (a)   the then 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, subtracted from

      (b)   the Adjusted Libor Rate applicable to the Libor Advance being
            prepaid.

      If the result of this calculation is zero or a negative number, then there
      shall be no LIBOR Rate Loan Prepayment Fee. If the result of this
      calculation is a positive number, then the resulting percentage shall be
      multiplied by:

      (c)   the amount of the Libor Advance being prepaid.

      The resulting amount shall be divided by:

      (d)   360

      and multiplied by:

      (e)   the number of days remaining in the Interest Period as to which the
            prepayment is being made.

      Said amount shall be reduced to present value calculated by using the
      referenced United States Treasury securities rate and the number of days
      remaining on the Interest Period for the Libor Advance being prepaid.

                                      -8-
<PAGE>

      The resulting amount of these calculations shall be the LIBOR Advance
      Prepayment Fee.

            2.5.16 Make Whole Provision. In addition to the LIBOR Rate Loan
      Prepayment Fee, the Borrower agrees to reimburse the Lenders (without
      duplication) for any increase in the cost to the Lenders, or reduction in
      the amount of any sum receivable by the Lenders, in respect, or as a
      result of:

            (a) any conversion or repayment or prepayment of the principal
      amount of any Libor Advances on a date other than the scheduled last day
      of the Interest Period applicable thereto, whether voluntary or otherwise;

            (b) any loans not being made as Libor Advances in accordance with
      the borrowing request thereof;

            (c) any Libor Advances not being continued as, or converted into,
      LIBOR Advances in accordance with the continuation/conversion notice
      thereof, or

            (d) without duplication of any costs incurred by the Borrower under
      any Hedging Contracts, any costs associated with marking to market any
      Hedging Obligations that (in the reasonable determination of the Agent
      unless another method of calculating costs is otherwise specified pursuant
      to the terms of any Hedging Contracts) are required to be terminated as a
      result of any conversion, repayment or prepayment of the principal amount
      of any LIBOR Advances on a date other than the scheduled last day of the
      Interest Period applicable thereto, whether voluntary or otherwise;

The Agent shall promptly notify the Borrower in writing of the occurrence of any
such event, such notice to state, in reasonable detail, the reasons therefore
and the additional amount required fully to compensate the Agent for such
increased cost or reduced amount. Such additional amounts shall be payable by
the Borrower to the Agent within five Business Days of its receipt of such
notice, and such notice shall, in the absence of manifest error, be conclusive
and binding on the Borrower. The Borrower understands, agrees and acknowledges
the following: (i) the Agent does not have any obligation to purchase, sell
and/or match funds in connection with the use of LIBOR Rate as a basis for
calculating the rate of interest on a LIBOR Advance, (ii) the LIBOR Rate may be
used merely as a reference in determining such rate, and (iii) the Borrower has
accepted the LIBOR Rate as a reasonable and fair basis for calculating such
rate, the LIBOR Rate Prepayment Fee, and other funding losses incurred by the
Lenders. Borrower further agrees to pay the LIBOR Rate Prepayment Fee and other
funding losses, if any, whether or not the Lenders elect to purchase, sell
and/or match funds.

      2.6 Additional Provisions Related to Interest Rate Selection.

            2.6.1 Increased Costs. If on or after the date hereof the adoption
      of any applicable law, rule or regulation or guideline (whether or not
      having the force of law), or any change therein, or any change in the
      interpretation or administration thereof by any governmental authority,
      central bank or comparable agency charged with the interpretation or
      administration thereof, or compliance by the Lenders with any request or
      directive (whether or not having the force of law) of any such authority,
      central bank or comparable agency:

            (a) shall subject the Lenders to any tax, duty or other charge with
            respect to its LIBOR Advances or its obligation to make LIBOR
            Advances, or shall change the basis of taxation of payments to the
            Lenders of the principal of or interest on its LIBOR Advances or any
            other amounts due under this agreement in respect of its LIBOR
            Advances or its obligation to make LIBOR Advances (except for the
            introduction of, or change in the rate of, tax on the overall net
            income of the Lenders or franchise taxes, imposed by the
            jurisdiction (or any political subdivision or taxing authority
            thereof) under the laws of which the Lenders are organized or in
            which the Lenders' principal executive offices are located); or

            (b) shall impose, modify or deem applicable any reserve, special
            deposit or similar requirement (including, without limitation, any
            such requirement imposed by the Board of Governors of the Federal
            Reserve System of the United States) against assets of, deposits
            with or for the account of, or credit extended by, the Lenders or
            shall impose on the Lenders or on the London interbank market any
            other condition affecting its LIBOR Advances or its obligation to
            make LIBOR Advances;

            and the result of any of the foregoing is to increase the cost to
      the Lenders of making or maintaining any LIBOR Advances, or to reduce the
      amount of any sum received or receivable by the Lenders under this
      Agreement with respect thereto, by an amount reasonably deemed by the
      Lenders to be material, then, within 15 days after written demand by the
      Agent (which demand shall specify in detail the reasons for same), the
      Borrower shall pay to the Lenders such additional amount or amounts as
      will compensate the Lenders for such increased cost or reduction.

            2.6.2 Increased Capital Costs. If any change in, or the
      introduction, adoption, effectiveness, interpretation, reinterpretation or
      phase-in of, any law or regulation, directive, guideline, decision or
      request (whether or not having the force of law) of any court, central
      bank, regulator or other governmental authority affects the amount of
      capital required or expected to be maintained by the Lender, and a Lender
      determines that the rate of return on capital as a consequence of its
      commitments or the loans made by the Lender is reduced to a level below

                                      -10-
<PAGE>

      that which the Lender could have achieved but for the occurrence of any
      such circumstance, then, in any such case upon written notice from time to
      time by the Lender to the Borrower, the Borrower shall promptly pay
      directly to the Lender additional amounts sufficient to compensate for
      such reduction in rate of return. A statement of the Lenders as to any
      such additional amount or amounts (including calculations thereof in
      reasonable detail) shall, in the absence of manifest error, be conclusive
      and binding on the Borrower. In determining such amount, the Lender may
      use any method of averaging and attribution that it shall deem applicable.

            2.6.3 Taxes. All payments by the Borrower of principal of, and
      interest on, the LIBOR Advances and all other amounts payable hereunder
      shall be made free and clear of and without deduction for any present or
      future income, excise, stamp taxes and other taxes, fees, duties,
      withholdings or other charges of any nature whatsoever imposed by any
      taxing authority, but excluding franchise taxes and taxes imposed on or
      measured by the Lender's net income or receipts (such non-excluded items
      being called "Taxes"). In the event that any withholding or deduction from
      any payment to be made by the Borrower hereunder is required in respect of
      any Taxes pursuant to any applicable law, rule or regulation, then the
      Borrower will

             (a) pay directly to the relevant authority the full amount required
       to be so withheld or deducted;

             (b) promptly forward to the Lender an official receipt or other
       documentation reasonably satisfactory to the Lender evidencing such
       payment to such authority; and

             (c) pay to the Lender such additional amount or amounts as is
       necessary to ensure that the net amount actually received by the Lender
       will equal the full amount the Lender would have received had no such
       withholding or deduction been required.

      Moreover, if any Taxes are directly asserted against the Lender with
      respect to any payment received by the Lender hereunder, the Lender may
      pay such Taxes and the Borrower will promptly pay such additional amount
      (including any penalties, interest or expenses) as is necessary in order
      that the net amount received by the Lender after the payment of such Taxes
      (including any Taxes on such additional amount) shall equal the amount the
      Lender would have received had not such Taxes been asserted.

      If the Borrower fails to pay any Taxes when due to the appropriate taxing
      authority or fails to remit to the Lender the required receipts or other
      required documentary evidence, the Borrower shall indemnify the Lender for
      any incremental Taxes, interest or penalties that may become payable by
      the Lender as a result of any such failure.

                                      -11-
<PAGE>

            2.6.4 Libor Rate Lending Unlawful. If the Agent shall determine
      (which determination shall, upon notice thereof to the Borrower be
      conclusive and binding on the Borrower) that the introduction of or any
      change in or in the interpretation of any law, rule, regulation or
      guideline, (whether or not having the force of law) makes it unlawful, or
      any central bank or other governmental authority asserts that it is
      unlawful, for the Lenders to make, continue or maintain any Libor Advance
      as, or to convert any loan into, a Libor Advance of a certain duration,
      the obligations of the Lenders to make, continue, maintain or convert into
      any such Libor Advances shall, upon such determination, forthwith be
      suspended until the Agent shall notify the Borrower that the circumstances
      causing such suspension no longer exist, and all Libor Advances of such
      type shall automatically convert into Variable Rate Loans at the end of
      the then current Interest Periods with respect thereto or sooner, if
      required by such law or assertion.

            2.6.5 Additional Libor Conditions. The selection by Borrower of an
      Adjusted Libor Rate and the maintenance of the Loan at such rate shall be
      subject to the following additional terms and conditions:

            (i) Substitute Rate. If the Agent shall have determined that

                  (a) US dollar deposits in the relevant amount and for the
            relevant Interest Period are not available to the Agent in the
            London interbank market;

                  (b) by reason of circumstances affecting the Agent in the
            London interbank, adequate means do not exist for ascertaining the
            Libor Rate applicable hereunder to Libor Advances of any duration,
            or

                  (c) Libor no longer adequately reflects the Lender's cost of
            funding loans,

      then, upon notice from the Agent to the Borrower, the obligations of the
      Lenders under Section 2.5 to make or continue any loans as, or to convert
      any loans into, Libor Advances of such duration shall forthwith be
      suspended until the Agent shall notify the Borrower that the circumstances
      causing such suspension no longer exist.

            2.6.6 Variable Rate Advances. Each Variable Rate Advance shall
      continue as a Variable Rate Advance until the Maturity Date of the Loan,
      unless sooner converted, in whole or in part, to a Libor Advance, subject
      to the limitations and conditions set forth in this Agreement.

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

                                      -12-
<PAGE>

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

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

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

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

2.8 Establishment of Letter of Credits. (a) Upon the written request of the
Borrower, the Issuing Lender agrees to cause the issuance of L/C's on behalf of
a Borrower as provided herein. The Borrower may request issuance of L/C's in
such manner as may from time to time be reasonably acceptable to the Issuing
Lender. The Borrower shall execute and deliver to the Issuing Lender such
further documents and instruments in connection with any L/C, as the Issuing
Lender, in accordance with the Issuing Lender's then customary practices with
respect to similar facilities, may reasonably request including, without

                                      -13-
<PAGE>

limitation, the Issuing Lender's standard letter of credit agreements (the "L/C
Agreement"). In the event of any inconsistency between the terms of the L/C
Agreement and this Agreement the terms and conditions of the L/C Agreement shall
control. By the issuance of a L/C (or an amendment to the L/C increasing the
Stated Amount thereof) by the Issuing Lender, and without any further action on
the part of the Issuing Lender or the Lenders, the Issuing Lender hereby grants
to each Lender, and each Lender hereby acquires from the Issuing Lender, an
undivided interest and participation in the L/C equal to such Lender's
Commitment Percentage of the aggregate amount available to be drawn under the
L/C. Each Lender acknowledges and agrees that its obligation to acquire
participations pursuant to this Section in respect of the L/C is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including any amendment, renewal or extension of the L/C or the occurrence and
continuance of a Default or Event of Default or reduction or termination of the
Commitment, and that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever. Notwithstanding anything to the
contrary contained in this Section 2.8(a), however, unless the Lenders'
expressly agree to the contrary, the Lenders shall have no obligation to accept
or acquire, and shall not be deemed to have accepted or acquired, any interest
or participation pursuant to this Section in respect of any L/C (or any
amendment increasing the Stated Amount of an L/C) if such L/C is issued (or such
amendment is entered into) by the Issuing Lender after the Termination Date, or
if the terms of the L/C or corresponding L/C Agreement (or any such amendment
thereto) is administered or enforced in a manner inconsistent with any of the
terms of this Agreement

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

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

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

      (b)   The Borrower will

            (i)   promptly examine the copy of any L/C (and any amendments
                  thereof) sent to it by the Issuing Lender;

            (ii)  promptly examine all instruments and documents delivered to it
                  from time to time by the Issuing Lender; and

                                      -14-
<PAGE>

            (iii) within two (2) Business Days of receipt thereof, provide the
                  Issuing Lender with written notice of any irregularity or
                  claim of non-compliance with the instructions of such person
                  or entity.

The Borrower is conclusively deemed to have waived any such claim against the
Issuing Lender and the Lenders and their correspondents unless such notice is so
timely given.

      (c)   None of the Issuing Lender, the Issuing Lender's correspondents or
            any advising, negotiating, or paying bank with respect to any L/C,
            shall be responsible in any way for:

                  (i)   performance by any beneficiary under any L/C or payee
                        under any L/C of that beneficiary's or payee's
                        obligations to the Borrower; or

                  (ii)  the form, sufficiency, correctness, genuineness,
                        authority of any person signing; falsification; or the
                        legal effect of; any documents called for under any L/C
                        if (with respect to the foregoing) such documents on
                        their face are conforming.

      (d)   The Issuing Lender may honor, as complying with the terms of any L/C
            and of any drawing thereunder, any drafts or other documents
            otherwise in order, but signed or issued by an administrator,
            executor, conservator, trustee in bankruptcy, debtor in possession,
            assignee for the benefit of creditors, liquidator, receiver, or
            other legal representative of the Person authorized under such L/C
            to draw or issue such drafts or other documents.

      (e)   Unless otherwise agreed to, in the particular instance, the Borrower
            hereby authorizes the Issuing Lender to (i) select an advising bank,
            if any; (ii) select a paying bank, if any; and (iii) select a
            negotiating bank.

      (f)   The Issuing Lender shall have discharged its obligations under any
            L/C which, or the drawing under which, includes payment
            instructions, by the initiation of the method of payment called for
            in, and in accordance with, such instructions (or by any other
            commercially reasonable and comparable method). The Issuing Lender
            does not assume any responsibility for any inaccuracy, interruption,
            error, or delay in transmission or delivery by post, telegraph or
            cable, or for any inaccuracy of translation.

      (g)   The Issuing Lender's rights, powers, privileges and immunities
            specified in or arising under this Agreement are in addition to any
            hereafter created or arising, whether by statute or rule of law or
            contract.

                                      -15-
<PAGE>

      (h)   Except to the extent otherwise expressly provided hereunder or
            agreed to in writing by the Issuing Lender, and the Borrower, the
            L/C will be governed by the Uniform Customs and Practice for
            Documentary Credits, International Chamber of Commerce, Publication
            No. 500, and any subsequent revisions thereof.

      (i)   If any change in any law, executive order or regulation, or any
            directive of any administrative or governmental authority (whether
            or not having the force of law), or in the interpretation thereof by
            any court or administrative or governmental authority charged with
            the administration thereof, shall either:

            (i)   impose, modify or deem applicable any reserve, special deposit
                  or similar requirements against L/C's hereafter caused to be
                  issued by the Issuing Lender or with respect to which the
                  Issuing Lender has an obligation to lend to fund drawings
                  thereunder; or

            (ii)  impose on any Issuing Lender any other condition or
                  requirements relating to any such L/C's;

and the result of any event referred to in clause (i) or (ii), above, shall be
to increase the cost to the Issuing Lender of issuing or maintaining any L/C,
then, upon demand by the Issuing Lender made within six (6) months of the
occurrence of any event referred to in clause (i) or (ii) above, and delivery by
the Issuing Lender to the Borrower of a certificate of an officer of the Lender
describing such change in law, executive order, regulation, directive, or
interpretation thereof, its effect on the Issuing Lender, and the basis for
determining such increased costs and their allocation, the Borrower within five
(5) Business Days after receipt of such notice shall pay to the Issuing Lender,
from time to time as specified by the Issuing Lender, such amounts as shall be
sufficient to compensate the Issuing Lender for such increased cost. The Issuing
Lender's determination of costs incurred under clause (i) or (ii) above, shall
be conclusive and binding on the Borrower in the absence of manifest error.

      (j)   The obligations of the Borrower under the within Agreement with

                  any guarantor or endorser of the Obligations, or any
                  governmental agency or authority or any other person (as well
                  as from attorneys' reasonable fees and expenses in connection
                  therewith) on account of the presence of hazardous material or
                  oil on any of the Borrowing Base Properties, the release of
                  hazardous materials or oil on or from any of the Borrowing
                  Base Properties, or the failure by the Borrower to comply with

                  Agent in favor of the Borrower; provided, however, that such
                  indemnification shall not apply to any claim brought or
                  threatened against the Agent and/or the Lenders and arising
                  from the Agent's and/or the Lenders' gross negligence or

other Loan Documents or any instrument pursuant to which the Obligations are
evidenced, including as permitted by applicable law the obtaining of the ex
parte appointment of a receiver, and, if any amount owed to the Agent or the
Lenders shall have become due, by declaration or otherwise, proceed to enforce
the payment thereof or any other legal or equitable right of the Agent or the
Lenders. No remedy conferred upon the Agent or the Lenders or the holder of the
Note in this Agreement or in any of the other Loan Documents is intended to be
exclusive of any other remedy and each and every remedy shall be cumulative and
shall be in addition to every other remedy given hereunder or thereunder or now
or hereafter existing at law or in equity or by statute or any other provision
of law.

11.4 Distribution of Proceeds. In the event that, following the occurrence and
during the continuance of any Default or Event of Default, the Agent receives
any monies, 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 and the Lenders for or in respect of all reasonable
            costs, expenses, disbursements and losses which shall have been
            incurred or sustained by the Lender in connection with the
            collection of such monies by the Agent and the Lenders, for the
            exercise, protection or enforcement by the Agent of all or any of
            the rights, remedies, powers and privileges of the Agent and the
            Lenders under this Agreement or any of the other Loan Documents or
            in support of any provision of adequate indemnity to the Agent and
            the Lenders against any taxes or liens which by law shall have, or
            may have, priority over the rights of the Lenders to such monies;

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

      (c)   Third, upon payment and satisfaction in full or other provisions for
            payment in full satisfactory to the Agent and the Lenders of all of
            the Obligations, to the payment of any obligations required to be
            paid pursuant to ss.9-615 of the Uniform Commercial Code of the
            Commonwealth of Massachusetts; and

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

15. LIABILITY OF THE AGENT AND THE LENDERS. The liability of the Agent and the
Lenders to the Borrower for any breach of the terms of this Agreement by the
Agent and the Lenders shall not exceed a sum equal to the amount which the
Lenders shall be determined to have failed to advance in consequence of a breach
by the Lenders of its obligations under this Agreement, together with interest
thereon at the rate payable by the Borrower under the terms of the Notes for
Advances which the Borrower is to receive hereunder, computed from the date when
the Advance should have been made by the Lenders to the date when the Advance
is, in fact, made by the Lenders, and, upon the making of any such payment by
the Lenders to the Borrower, the same shall be treated as an Advance under this
Agreement, in the same fashion as any other Advance under the terms of this
Agreement. In no event shall the Lenders be liable to the Borrower, or anyone
claiming by, under or through the Borrower, for any special, exemplary, punitive
or consequential damages, whatever the nature of the breach of the terms of this
Agreement by the Agent or the Lenders, such damages and claims therefor being
expressly WAIVED by the Borrower.

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

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

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

                                      -45-

to the Agent or the Lenders at any time by or on behalf of any Person or any
Subsidiary thereof pursuant hereto or in connection with the transactions
contemplated hereby shall constitute representations and warranties by such
Person.

      18.1 Appointment of Agent. Each Lender hereby irrevocably designates and
appoints RBS Citizens, National Association as Agent of such Lender to act as
specified herein and in the other Loan Documents, and each such Lender hereby
irrevocably authorizes the Agent to take such actions, exercise such powers and
perform such duties as are expressly delegated to or conferred upon the Agent by
the terms of this Agreement and the other Loan Documents, together with such
other powers as are reasonably incidental thereto. The Agent agrees to act as
such upon the express conditions contained in this Article 18. The Agent shall
not have any duties or responsibilities except those expressly set forth herein
or in the other Loan Documents, nor shall it have any fiduciary relationship
with any Lender, and no implied covenants, responsibilities, duties, obligations
or liabilities shall be read into this Agreement or otherwise exist against the
Agent. Except as specifically provided herein, the provisions of this Article 18
are solely for the benefit of the Agent and the Lenders, and the Borrower shall
not have any rights as a third party beneficiary of any of the provisions
hereof.

      18.2 Administration of Loan by Agent. The Agent shall be responsible for
administering the Loan on a day-to-day basis. In the exercise of such
administrative duties, the Agent shall use the same diligence and standard of
care that is customarily used by the Agent with respect to similar loans held by
the Agent solely for its own account.

      Each Lender delegates to the Agent the full right and authority on its
behalf to take the following specific actions in connection with its
administration of the Loan:

            (i) to fund the Loan in accordance with the provisions of the Loan
      Documents, but only to the extent of immediately available funds provided
      to the Agent by the respective Lenders for such purpose;

            (ii) to receive all payments of principal, interest, fees and other
      charges paid by, or on behalf of, the Borrower and, except for fees to
      which the Agent is entitled pursuant to the Loan Documents or otherwise,
      to distribute all such funds to the respective Lenders as provided for
      hereunder;

            (iii) to keep and maintain complete and accurate files and records
      of all material matters pertaining to the Loan, and make such files and
      records available for inspection and copying by each Lender and its
      respective employees and agents during normal business hours upon
      reasonable prior notice to the Agent; and

                                      -46-
<PAGE>

            (iv) to do or omit doing all such other actions as may be reasonably
      necessary or incident to the implementation, administration and servicing
      of the Loan and the rights and duties delegated hereinabove.

      18.3 Delegation of Duties. The Agent may execute any of its duties under
this Loan Agreement or any other Loan Document by or through its agent or
attorneys-in-fact, and shall be entitled to the advice of counsel concerning all
matters pertaining to its rights and duties hereunder or under the Loan
Documents. The Agent shall not be responsible for the negligence or misconduct
of any agents or attorneys-in-fact selected by it with reasonable care.

      18.4 Exculpatory Provisions. Neither the Agent nor any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates shall be liable to
the Lenders for any action lawfully taken or omitted to be taken by it or them
under or in connection with this Agreement or the other Loan Documents, except
for its or their gross negligence or willful misconduct. Neither the Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be responsible for or have any duty to ascertain, inquire into,
or verify (i) any recital, statement, representation or warranty made by the
Borrower or any of its officers or agents contained in this Agreement or the
other Loan Documents or in any certificate or other document delivered in
connection therewith; (ii) the performance or observance of any of the covenants
or agreements contained in, or the conditions of, this Agreement or the other
Loan Documents; (iii) the state or condition of any properties of the Borrower
or any other obligor hereunder constituting collateral for the Obligations of
the Borrower hereunder, or any information contained in the books or records of
the Borrower; (iv) the validity, enforceability, collectibility, effectiveness
or genuineness of this Loan Agreement or any other Loan Document or any other
certificate, document or instrument furnished in connection therewith; or (v)
the validity, priority or perfection of any lien securing or purporting to
secure the Obligations or the value or sufficiency of any collateral.

      18.5 Reliance by Agent. The Agent shall be entitled to rely, and shall be
fully protected in relying, upon any notice, consent, certificate, affidavit, or
other document or writing believed by it to be genuine and correct and to have
been signed, sent or made by the proper person or persons, and upon the advice
and statements of legal counsel (including, without limitation, counsel to the
Borrower), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified (as to the Lenders) in failing or refusing to
take any action under this Agreement or any other Loan Document unless it shall
first receive such advice or concurrence of the Required Lenders as it deems
appropriate or its shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of the taking or failing to take any such action. The Agent shall in all cases
be fully protected from the Lenders in acting, or in refraining from acting,
under this Agreement and the other Loan Documents in accordance with any written
request of the Required Lenders, and each such request of the Required Lenders,
and any action taken or failure to act by the Agent pursuant thereto, shall be
binding upon all of the Lenders; provided, however, that the Agent shall not be
required in any event to act, or to refrain from acting, in any manner which is
contrary to the Loan Documents or to applicable law.

                                      -47-
<PAGE>

      18.6 Notice of Default. The Agent shall not be deemed to have knowledge or
notice of the occurrence of any Event of Default unless the Agent has actual
knowledge of the same or has received notice from a Lender or the Borrower
referring to this Agreement, describing such Event of Default and stating that
such notice is a "notice of default". In the event that the Agent obtains such
actual knowledge or receives such a notice, the Agent shall give prompt notice
thereof to each of the Lenders. The Agent shall take such action with respect to
such Event of Default as shall be reasonably directed by the Required Lender
unless and until the Agent shall have received such direction, the Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to any such Event of Default as it shall deem advisable in
the best interest of the Lenders, provided, however, that the Agent shall not
accelerate the indebtedness under this Loan Agreement without the prior written
consent of the Required Lenders.

      18.7 Lenders' Credit Decisions. Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender, and based
on the financial statements prepared by the Borrower and such other documents
and information as it has deemed appropriate, made its own credit analysis and
investigation into the business, assets, operations, property, and financial and
other condition of the Borrower and has made its own decision to enter into this
Agreement and the other Loan Documents. Each Lender also acknowledges that it
will, independently and without reliance upon the Agent or any other Lender, and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in determining whether or not
conditions precedent to closing any Loan hereunder have been satisfied and in
taking or not taking any action under this Agreement and the other Loan
Documents. Each Lender expressly acknowledges that is has relied upon its own
legal counsel in its consideration of its decision to enter into the Agreement
and the other Loan Documents and will so rely in regard to the implementation of
the transaction contemplated hereby and thereby and that it does not have any
lawyer-client relationship with Agent's counsel or counsels or any other Lenders
with respect thereto.

      18.8 Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent, ratably in proportion to their respective
Commitments, for (i) any amounts not reimbursed by the Borrower for which the
Agent is entitled to reimbursement by the Borrower under this Agreement or the
other Loan Documents, (ii) any other expenses incurred by the Agent on behalf of
the Lenders in connection with the preparation, execution, delivery,
administration, amendment, waiver and/or enforcement of this Agreement and the
other Loan Documents, and (iii) any liabilities, obligations, losses, damages,
penalties, action, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Agent in any way relating to or arising out of this Agreement or the
other Loan Documents or any other document delivered in connection therewith or
any transaction contemplated thereby, or the enforcement of any of the terms

                                      -48-
<PAGE>

hereof or thereof, provided that no Lender shall be liable for any of the
foregoing to the extent that they arise from the gross negligence or willful
misconduct of the Agent. If any indemnity furnished to the Agent for any purpose
shall, in the opinion of the Agent, be insufficient or become impaired, the
Agent may call for additional indemnity and cease, or not commence, to do the
action indemnified against until such additional indemnity is furnished.

      18.9 Agent in its Individual Capacity. With respect to its Commitment as a
Lender, and the Loans made by it and the Note issued to it, the Agent shall have
the same rights and powers hereunder and any other Loan Document as any Lender
and may exercise the same as thought it were not the Agent, and the term
"Lender" or "Lenders" shall, unless the context otherwise indicates, include the
Agent in its individual capacity. The Agent and its subsidiaries and affiliates
may accept deposits from, lend money to, and generally engage in any kind of
commercial or investment banking, trust, advisory or other business with the
Borrower or any subsidiary or affiliate of the Borrower as if it were not the
Agent hereunder.

      18.10 Successor Agent. The Agent may resign at any time by giving thirty
(30) days' prior written notice to the Lenders and Borrower. The Required
Lenders, for good cause, may remove Agent at any time by giving thirty (30)
days' prior written notice to the Agent, the Borrower and the other Lenders.
Upon any such resignation or removal, the Required Lenders shall have the right
to appoint a successor Agent. If no successor Agent shall have been so appointed
by the Required Lenders and accepted such appoint within thirty (30) days after
the retiring Agent's giving notice of resignation or the Required Lenders'
giving notice of removal, as the case may be, then the retiring Agent may
appoint, on behalf of the Borrower and the Lenders, a successor Agent. Each such
successor Agent shall be a financial institution which meets the requirements of
an Eligible Assignee. Unless an Event of Default shall have occurred and be
continuing, any successor Agent shall be reasonably acceptable to the Borrower.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder and under
the other Loan Documents. After any retiring Agent's resignation hereunder, the
provisions of this Article 18 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
the Agent hereunder.

      18.11 Duties in the Case of Enforcement. In the case one or more Events of
Default have occurred and shall be continuing, and whether or not acceleration
of the Obligations shall have occurred, the Agent shall, at the request, or may,
upon the consent, of the Required Lenders, and provided that the Lenders have
given to the Agent such additional indemnities and assurances against expenses
and liabilities as the Agent may reasonably request, proceed to enforce the
provisions of this Loan Agreement and the other Loan Documents respecting the
exercise of any legal or equitable rights or remedies as it may have hereunder
or under any other Loan Document or otherwise by virtue of applicable law, or to
refrain from so acting if similarly requested by the Required Lenders. The Agent

                                      -49-
<PAGE>

shall be fully protected as to the Lenders in so acting or refraining from
acting upon the instruction of the Required Lenders, and such instruction shall
be binding upon all the Lenders. The Required Lenders may direct the Agent in
writing as to the method and the extent of any such foreclosure, sale or other
disposition or the exercise of any other right or remedy, the Lenders hereby
agree to indemnify and hold the Agent harmless from all costs and liabilities
incurred in respect of all actions taken or omitted in accordance with such
direction, provided that the Agent need not comply with any such direction to
the extent that the Agent reasonably believes the Agent's compliance with such
direction to be unlawful or commercially unreasonable in any applicable
jurisdiction. The Agent may, in its discretion but without obligation, in the
absence of direction from the Required Lenders, take such interim actions as it
believes necessary to preserve the rights of the Lenders hereunder, including
but not limited to petitioning a court for injunctive relief, appointment of a
receiver or preservation of the proceeds of any action taken. Each of the
Lenders acknowledges and agrees that no individual Lender may separately enforce
or exercise any of the provisions of any of the Loan Documents, including
without limitation the Notes, other than through the Agent.

      18.12 Respecting Loans and Payments.

            18.12.1 Procedures for Loans. Agent shall give written notice to
      each Lender of each request for a conversion of an existing Loan from a
      Variable Rate Advance to a Libor Advance, by facsimile transmission, hand
      delivery or overnight courier, not later than 11:00 a.m. (Boston time) (i)
      two (2) Business Days prior to any Libor Advance or conversion to a Libor
      Advance, or (ii) one (1) Business Day prior to any Variable Rate Advance.
      Each such notice shall be accompanied by a written summary of the request
      for a Loan and shall specify (a) the date of the requested Loan, (b) the
      aggregate amount of the requested Loan, (c) each Lender's pro rata share
      of the requested Loan, and (d) the applicable interest rate selected by
      Borrower with respect to such Loan, or any portion thereof, together with
      the applicable Interest Period, if any, selected, or deemed selected, by
      Borrower. Each Lender shall, before 11:00 a.m. (Boston time) on the date
      set forth in any such request for a Loan, make available to Agent, at an
      account to be designated by Agent at RBS Citizens, National Association in
      Boston, Massachusetts, in same day funds, each Lender's ratable portion of
      the requested Loan. After Agent's receipt of such funds and upon Agent's
      determination that the applicable conditions to making the requested Loan
      have been fulfilled, Agent shall make such funds available to Borrower as
      provided for in this Loan Agreement. Promptly after receipt by Agent of
      written request from any Lender, Agent shall deliver to the requesting
      Lender a copy of the Borrower's request for Loans and the accompanying
      certifications and such other instruments, documents, certifications and
      approvals delivered by or on behalf of Borrower to Agent in support of the
      requested Loan.

            18.12.2 Nature of Obligations of Lenders. The obligations of the
      Lenders hereunder are several and not joint. Failure of any Lender to
      fulfill its obligations hereunder shall not result in any other Lender
      becoming obligated to advance more than its Commitment Percentage of the
      Loan, nor shall such failure release or diminish the obligations of any
      other Lender to fund its Commitment Percentage provided herein.

                                      -50-
<PAGE>

            18.12.3 Payments to Agent. All payments of principal of and interest
      on the Loans or the Notes shall be made to the Agent by the Borrower or
      any other obligor or guarantor for the account of the Lenders in
      immediately available funds as provided in the Notes and this Agreement.
      The Agent agrees promptly to distribute to each Lender, on the same
      Business Day upon which each such payment is made if possible, such
      Lender's proportionate share of each such payment in immediately available
      funds, except as otherwise expressly provided herein. The Agent shall upon
      each distribution promptly notify Borrower of such distribution and each
      Lender of the amounts distributed to it applicable to principal of, and
      interest on, the proportionate share held by the applicable Lender. Each
      payment to the Agent under the first sentence of this Section 18.12.3
      shall constitute a payment by the Borrower to each Lender in the amount of
      such Lender's proportionate share of such payment, and any such payment to
      the Agent shall not be considered outstanding for any purpose after the
      date of such payment by the Borrower to the Agent without regard to
      whether or when the Agent makes distribution thereof as provided above. If
      any payment received by the Agent from the Borrower is insufficient to pay
      both all accrued interest and all principal then due and owing, the Agent
      shall first apply such payment to all outstanding interest until paid in
      full and shall then apply the remainder of such payment to all principal
      then due and owing, and shall distribute the payment to each Lender
      accordingly.

            18.12.4 Distribution of Liquidation Proceeds. Subject to the terms
      and conditions hereof, the Agent shall distribute all Liquidation Proceeds
      in the order and manner set forth below:

      First:      To the Agent, towards any fees and any expenses for which the
                  Agent is entitled to reimbursement under this Agreement or the
                  other Loan Documents not theretofore paid to the Agent.

      Second:     To all applicable Lenders in accordance with their
                  proportional share based upon their respective Commitment
                  Percentages until all Lenders have been reimbursed for all
                  expenses which such Lenders have previously paid to the Agent
                  and not theretofore paid to such Lenders.

      Third:      To all applicable Lenders based upon their respective
                  Commitment Percentages until all Lenders have been paid in
                  full any Individual Lender Litigation Expenses.

      Fourth:     To all Lenders in accordance with their proportional share
                  based upon their respective Commitment Percentages until all
                  Lenders have been paid in full all principal and interest due

                                      -51-
<PAGE>

                  to such Lenders under the Loan, with each Lender applying such
                  proceeds for purposes of this Agreement first against the
                  outstanding principal balance due to such Lender under the
                  Loan and then to accrued and unpaid interest due under the
                  Loan.

      Fifth:      To all applicable Lenders in accordance with their
                  proportional share based upon their respective Commitment
                  Percentages until all Lenders have been paid in full all other
                  amounts due to such Lenders under the Loan including, without
                  limitation, any costs and expenses incurred directly by such
                  Lenders to the extent such costs and expenses are reimbursable
                  to such Lenders by the Borrower under the Loan Documents.

      Sixth:      To the Borrower or such third parties as may be entitled to
                  claim Liquidation Proceeds.

            18.12.5 Adjustments. If, after Agent has paid each Lender's
      proportionate share of any payment received or applied by Agent in respect
      of the Loan, that payment is rescinded or must otherwise be returned or
      paid over by Agent, whether pursuant to any bankruptcy or insolvency law,
      sharing of payments clause of any loan agreement or otherwise, such Lender
      shall, at Agent's request, promptly return its proportionate share of such
      payment or application to Agent, together with the Lender's proportionate
      share of any interest or other amount required to be paid by Agent with
      respect to such payment or application.

            18.12.6 Setoff. If any Lender (including the Agent), acting in its
      individual capacity, shall exercise any right of setoff against a deposit
      balance or other account of the Borrower held by such Lender on account of
      the obligations of the Borrower under this Agreement, such lender shall
      remit to the Agent all such sums received pursuant to the exercise of such
      right of setoff, and the Agent shall apply all such sums for the benefit
      of all of the Lenders hereunder in accordance with the terms of this
      Agreement.

            18.12.7 Distribution by Agent. If in the opinion of the Agent
      distribution of any amount received by it in such capacity hereunder or
      under the Notes or under any of the other Loan Documents might involve any
      liability, it may refrain from making distribution until its right to make
      distribution shall have been adjudicated by a court of competent
      jurisdiction or has been resolved by the mutual consent of all Lenders. In
      addition, the Agent may request full and complete indemnity, in form and
      substance satisfactory to it, prior to making any such distribution. 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 to the same in such manner and to such persons as shall be determined
      by such court.

                                      -52-

      18.13 Delinquent Lender. If for any reason any Lender shall fail or refuse
to abide by its obligations under the Agreement, including without limitation
its obligation to make available to Agent its pro rata share of any Loan,
expenses or setoff (a "Delinquent Lender") and such failure is not cured within
ten (10) days of receipt from the Agent of written notice thereof, then, in
addition to the rights and remedies that may be available to Agent, other
Lenders, the Borrower or any other party at law or in equity, and not at
limitation thereof, (i) such Delinquent Lender's right to participate in the
administration of, or decision-making rights related to, the Loans, this
Agreement or the other Loan Documents shall be suspended during the pendency of
such failure or refusal, and (ii) a Delinquent Lender shall be deemed to have
assigned any and all payments due to it from the Borrower, whether on account of
the outstanding Loans, interest, fees or otherwise, to the remaining
non-delinquent Lenders for application to, and reduction of, their proportionate
shares of the outstanding Loans until, as a result of application of such
assigned payments the Lenders' respective pro rata shares of all the outstanding
Loans shall have returned to those in effect immediately prior to such
delinquency and without giving effect to the nonpayment causing such
delinquency. The Delinquent Lender's decision-making and participation rights to
payments as set forth in clauses (i) and (ii) hereinabove shall be restored only
upon the payment by the Delinquent Lender of its pro rata share of any Loans or
expenses as to which it is delinquent, together with interest thereon at the
Default Rate from the date when originally due until the date upon which any
such amounts are actually paid.

      The non-delinquent Lenders shall also have the right, but not the
obligation, in their respective, sole and absolute discretion, to acquire for no
cash consideration (pro rata, based on the respective Commitments of those
Lenders electing to exercise such right) the Delinquent Lender's Commitment to
fund future Loans (the "Future Commitment"). Upon any such purchase of the pro
rata share of any Delinquent Lender's Future Commitment, the Delinquent Lender's
share in future Loans and its rights under the Loan Documents with respect
thereto shall terminate on the date of purchase, and the Delinquent Lender shall
promptly execute all documents reasonably requested to surrender and transfer
such interest, including, if so requested, an Assignment and Acceptance. Each
Delinquent Lender shall indemnify Agent and each non-delinquent Lender from and
against any and all loss, damage or expenses, including but not limited to
reasonable attorneys' fees and funds advanced by Agent or by any non-delinquent
Lender, on account of an Delinquent Lender's failure to timely fund its pro rata
share of a Loan or to otherwise perform its obligations under the Loan
Documents.

      18.14 Holders. The Agent may deem and treat the payee of any Note as the
owner thereof for all purposes hereof unless and until a written notice of the
assignment, transfer or endorsement thereof, as the case may be, shall have been
filed with the Agent. Any request, authority or consent of any person or entity
who, at the time of making such request or giving such authority or consent, is
the holder of any Note shall be conclusive and binding on any subsequent holder,
transferee or endorsee, as the case may be, of such Note or of any Note or Notes
issued in exchange therefor.

      if an assignment is to an Eligible Assignee), (b) each such assignment
      shall be of a constant, and not a varying, percentage of all the assigning
      Lender's rights and obligations under this Agreement, (c) prior to the
      occurrence of an Event of Default and while same is continuing each
      assignment shall be in an amount that is at least Five Million Dollars

      defined), an Assignment and Acceptance, substantially in the form of
      Exhibit E hereto (an "Assignment and Acceptance"), together with any Notes
      subject to such assignment. Upon such execution, delivery, acceptance and
      recording, from and after the effective date specified in each Assignment
      and Acceptance, which effective date shall be at least five (5) Business

<PAGE>

                  (ii) the assigning Lender makes no representation or warranty
            and assumes no responsibility with respect to the financial
            condition of the Borrower and its affiliates, related entities or
            subsidiaries or any other person primarily or secondarily liable in
            respect of any of the Obligations, or the performance or observance
            by the Borrower or any other person primarily or secondarily liable
            in respect of any of the Obligations or any of their obligations
            under this Agreement or any of the other Loan Documents or any other
            instrument or document furnished pursuant hereto or thereto;

                  (iii) such assignee confirms that it has received a copy of
            this Agreement, together with copies of the most recent financial

            has deemed appropriate to make its own credit analysis and decision
            to enter into such Assignment and Acceptance;

                  (iv) such assignee will, independently and without reliance
            upon the assigning Lender, the Agent or any other Lender and based
            on such documents and information as it shall deem appropriate at
            the time, continue to make its own credit decisions in taking or not
            taking action under this Agreement;

                  (v) such assignee represents and warrants that it is an
            Eligible Assignee if required hereunder;

                  (vi) such assignee appoints and authorizes the Agent to take
            such action as agent on its behalf and to exercise such powers under
            this Agreement and the other Loan Documents as are delegated to the
            Agent by the terms hereof or thereof, together with such powers as
            are reasonably incidental thereto;

                  (vii) such assignee agrees that it will perform in accordance
            with their terms all of the obligations that by the terms of this
            Agreement are required to be performed by it as a Lender; and

                  (viii) such assignee represents and warrants that it is
            legally authorized to enter into such Assignment and Acceptance.

            18.15.3 Register. The Agent shall maintain a copy of each Assignment
      and Acceptance delivered to it and a register or similar list (the
      "Register") for the recordation of the names and addresses of the Lenders
      and the Commitment Percentage of, and principal amount of the Loans owing
      to the Lenders from time to time. The entries in the Register shall be
      conclusive, in the absence of manifest error, and the Borrower, the Agent

                                      -55-
<PAGE>

      and the Lenders may treat each person whose name is recorded in the
      Register as a Lender hereunder available for inspection by the Borrower
      and the Lenders at any reasonable time and from time to time upon
      reasonable prior notice. Upon each such recordation, the assigning Lender
      agrees to pay to the Agent a registration fee in the sum of Three Thousand
      Five Hundred Dollars ($3,500.00).

            18.15.4 New Notes. Upon its receipt of an Assignment and Acceptance
      executed by the parties to such assignment, together with each Note
      subject to such assignment, the Agent shall (a) record the information
      contained therein in the Register, and (b) give prompt notice thereof to
      the Borrower and the Lenders (other than the assigning Lender). Within
      five (5) Business Days after receipt of such notice, the Borrower, at its
      own expense, shall execute and deliver to the Agent, in exchange for each
      surrendered Note, a new Note to the order of such Eligible Assignee
      pursuant to such Assignment and Acceptance and, if the assigning Lender
      has retained some portion of its obligations hereunder, a new Note to the
      order of the assigning Lender in an amount equal to the amount retained by
      it hereunder. Such new Notes shall provide that they are replacements for
      the surrendered Notes, shall be in an aggregate principal amount equal to
      the aggregate principal amount of the surrendered Notes, shall be dated
      the effective date of such Assignment and Acceptance and shall otherwise
      be substantially in the form of the assigned Notes. The surrendered Notes
      shall be canceled and returned to the Borrower.

            18.15.5 Participations. Each Lender may sell participations to one
      or more banks or other financial institutions in all or a portion of such

      Documents; provided that (a) each such Participation shall be in a minimum
      amount of Five Million Dollars ($5,000,000.00), (b) as long as no Event of
      Default exists each participant shall meet the requirements of an Eligible
      Assignee, (c) any such sale or participation shall not affect the rights
      and duties of the selling Lender hereunder to the Borrower, and (d) the
      only rights granted to the participant pursuant to such participation
      arrangements with respect to waivers, amendments or modifications of the
      Loan Documents shall be the rights to approve waivers, amendments or
      modifications that would reduce the principal of or the interest rate on
      any Loans, extend the term or increase the amount of the Commitment of
      such Lender as it relates to such participant, reduce the amount of any
      commitment fees to which such participant is entitled or extend any
      regularly scheduled payment date for principal or interest.

            18.16 Disclosure. The Borrower agrees that in addition to
      disclosures made in accordance with standard and customary banking
      practices any Lender may disclose information obtained by such Lender
      pursuant to this Agreement to assignees or participants and potential
      assignees or participants hereunder; provided that such assignees or
      participants or potential assignees or participants shall agree (a) to

                                      -56-

      treat in confidence such information unless such information otherwise
      becomes public knowledge, (b) not to disclose such information to a third
      party except as required by law or legal process and (c) not to make use
      of such information for purposes of transactions unrelated to such
      contemplated assignment or participation. The Agent and the Lenders agree
      to maintain the confidentiality of the Information (as defined below),
      except that Information may be disclosed (a) to it and its affiliates'
      directors, officers, employees and agents, including accountants, legal
      counsel and other advisors (it being understood that the Persons to whom
      such disclosure is made will be informed of the confidential nature of
      such Information and instructed to keep such Information confidential),
      (b) to the extent requested by any regulatory authority, (c) to the extent
      required by applicable laws or regulations or by any subpoena or similar
      legal process, (d) to any other party hereto, (e) in connection with the
      exercise of any remedies hereunder or under any other Loan Document or any
      action or proceeding relating to this Agreement or any other Loan Document
      or the enforcement of rights hereunder or thereunder, (f) subject to an
      agreement containing provisions substantially the same as those of this
      Section, to (i) any assignee of or participant in, or any prospective
      assignee of or participant in, any of its rights or obligations under this
      Agreement or (ii) any actual or prospective counterparty (or its advisors)
      to any swap or derivative transaction relating to the Borrower and its
      obligations, (g) with the written consent of the Borrower or (h) to the
      extent such Information (x) becomes publicly available other than as a
      result of a breach of this Section or (y) becomes available to the Agent
      or the Lenders on a nonconfidential basis from a source other than the
      Borrower. For purposes of this Section, "Information" means all
      information received from the Borrower relating to the Borrower or any of
      its businesses, other than any such information that is available to the
      Agent or the Lenders on a nonconfidential basis prior to disclosure by the
      Borrower, provided that, in the case of information received from the
      Borrower after the date hereof, such information either (x) consists of
      financial statements or (y) is clearly identified at the time of delivery
      as confidential. Any Person required to maintain the confidentiality of
      Information as provided in this Section shall be considered to have
      complied with its obligation to do so if such Person has exercised the
      same degree of care to maintain the confidentiality of such Information as
      such Person would accord to its own confidential information.

      18.17 Miscellaneous Assignment Provisions. Any assigning Lender shall
retain its rights to be indemnified pursuant to Section 14 with respect to any
claims or actions arising prior to the date of such assignment. If any assignee
Lender is not incorporated under the laws of the United States of America or any
state thereof, it shall prior to the date on which any interest or fees
are-payable hereunder or under any of the other Loan Documents for its account,
deliver to the Borrower and the Agent certification as to its exemption from
deduction or withholding of any United States federal income taxes. Anything
contained in this Section 18.17 to the contrary notwithstanding, any Lender may
at any time pledge all or any portion of its interest and rights under this
Agreement (including all or any portion of its Notes to any of the twelve
Federal Reserve Banks organized under ss.4 of the Federal Reserve Act, 12
U.S.C.ss.341). No such pledge or the enforcement thereof shall release the
pledgor Lender from its obligations hereunder or under any of the other Loan
Documents.

      18.18 Amendment, Waiver, Consent, Etc. No term or provision of this
Agreement or any other Loan Document may be changed, waived, discharged or
terminated, nor may any consent required or permitted by this Agreement or any

            interest or fees thereon, (c) increasing or reducing the principal

                  (v) releases or waives any of the indemnifications provided in
            the Loan Documents;

provisions of any Loan Document which relates to the rights or obligations of
the Agent.

      18.19 Deemed Consent or Approval. With respect to any requested amendment,
waiver, consent or other action which requires the approval of the Required
Lenders or all of the Lenders, as the case may be in accordance with the terms
of this Agreement, or if the Agent is required hereunder to seek or desires to
seek, the approval of the Required Lenders or all of the Lenders, as the case
may be, prior to undertaking a particular action or course of conduct, the Agent
in each such case shall provide each Lender with written notice of any such
request for amendment, waiver or consent or any other requested or proposed

                                      -58-
<PAGE>

action or course of conduct, accompanied by such detailed background information
and explanations as may be reasonably necessary to determine whether to approve
or disapprove such amendment, waiver, consent or other action or course of
conduct, the Agent may (but shall not be required to) include in any such
notice, printed in capital letters or boldface type a legend substantially to
the following effect;

      "THIS COMMUNICATION REQUIRES IMMEDIATE RESPONSE, FAILURE TO RESPOND WITHIN
      TEN (10) CALENDAR DAYS FROM THE RECEIPT OF THIS COMMUNICATION SHALL
      CONSTITUTE A DEEMED APPROVAL BY THE ADDRESSEE OF THE ACTION REQUESTED BY
      THE BORROWER OR THE COURSE OF CONDUCT PROPOSED BY THE AGENT AND RECITED
      ABOVE."

and if the foregoing legend is included by the Agent in its communication, a
Lender shall be deemed to have approved or consented to such action or course of
conduct for all purposes hereunder if such Lender fails to object to such action
or course of conduct by written notice to the Agent within ten (10) calendar
days of such Lender's receipt of such notice.

19. NO ASSIGNMENT BY THE BORROWER . The Borrower shall not assign or transfer
any of its rights or obligations under any of the Loan Documents without the
prior approval of the Lenders.

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

21. NOTICES. Except as otherwise provided herein or in any other Loan Document,
each notice, demand, election or request provided for or permitted to be given
pursuant to this Agreement (hereinafter in this Section referred to as "Notice")
