                             COMMITMENTS OF THE BANK

      2.1 Commitment. Prior to the Maturity Date and subject to the terms and
conditions of this Agreement, the Bank agrees to lend to the Borrowers, jointly
and severally and secured by

                                       3
<PAGE>

the Collateral, up to the amount of the Commitment in the aggregate outstanding
at any time in the form of loans ("Advances"), provided, that the Permitted
Investments to which such Advance relate have been credited to the Investment
Collateral Account (as defined in the Pledge and Security Agreement), and
provided however, that the principal amount of any Advance shall not exceed the
purchase price of the Permitted Investments that shall be purchased with the
proceeds of such Advance. Within the foregoing limits, and subject to the
additional terms and conditions of this Agreement, the Borrowers may from time
to time borrow, repay in whole or in part and reborrow, regardless of the
cumulative amount of the Advances. The Bank shall not be obligated to make
Advances if, after giving effect thereto, any of the foregoing limitations would
be exceeded.

      2.2 Use of Proceeds of Advances. The Advances shall be used solely to
purchase Permitted Investments, which Permitted Investments will be credited to
the Investment Collateral Account and included in the Collateral.

      2.3 Optional Reduction or Termination of Commitment. The Borrowers may, at
any time, upon no less than three Business Days' prior written notice to the
Bank, reduce the Commitment, with any such reduction in a minimum amount of
$1,000,000 or an integral multiple thereof. Upon any reduction in the Commitment
pursuant to this Section, the Borrowers shall pay to the Bank the amount, if
any, by which the aggregate unpaid principal amount of outstanding Advances
exceeds the Commitment as so reduced. Amounts so paid cannot be reborrowed. The
Borrowers may, at any time, upon not less than three Business Days' prior
written notice to the Bank, terminate the Commitment in its entirety. Upon
termination of the Commitment pursuant to this Section, the Borrowers shall pay
to the Bank the full amount of all outstanding Advances, all accrued and unpaid
interest thereon, and all other unpaid obligations of the Borrowers to the Bank
hereunder.

      2.4 Time and Method of Payments. All payments and prepayments by the
Borrowers of principal of the Notes shall be made in Immediately Available Funds
not later than 12:00 noon (Minneapolis time) on the dates called for under this
Agreement at the main office of the Bank in Minneapolis, Minnesota. Funds
received after such hour shall be deemed to have been received by the Bank on
the next Business Day. The Borrowers hereby authorize the Bank to charge the
Cash Collateral Account in an amount equal to any such payment or prepayment
when due and payable to the Bank under this Agreement on the date due and agrees
to maintain collected funds in such Cash Collateral Account sufficient to make
such payments as and when due. If any payment of principal on the Notes becomes
due and payable on a day which is not a Business Day, such payment shall be made
on the next succeeding Business Day and such extension of time shall in such
case be included in the computation of any interest on such principal payment.

      2.5 Borrowing of Advances. The Borrowers shall give the Bank telephonic
notice of each request for an Advance (promptly confirmed in writing) under the
Commitment not later than 12:00 noon (Minneapolis time) on the date of the
requested Advance, specifying the amount requested; provided, that the Borrowers
shall have a reasonable expectation of maintaining Available Balances so that no
"Deficiency" (as determined in accordance with Section 2.9) shall exist for such
month. Each request for an Advance shall specify the date and the amount of such
Advance which shall be in a minimum amount of $100,000. The Bank shall deposit
into the

                                       4
<PAGE>

Cash Collateral Account in Immediately Available Funds by not later than 5:00
P.M. (Minneapolis time) on said date the total amount of the Advance or Advances
to be made by the Bank. Upon such deposit, the Cash Collateral Account will be
debited to purchase the related Permitted Investments and, upon such purchase,
such Permitted Investments will be credited to the Investment Account.

      2.6 Note Evidencing Advances. All Advances shall be evidenced by the Note.
The date and amount of each Advance may be noted by the Bank on a schedule
annexed to the Note or on the Bank's ledgers or computer records. The aggregate
amount of Advances made by the Bank under the Note less repayments of principal
thereof shall be the principal amount owing and unpaid on the Note. The
notations made by a Bank on the schedule annexed to the Note or its ledgers and
computer records shall be presumed to be accurate absent manifest error,
provided however, that the failure of the Bank to make such notations or to
maintain such records shall not affect the validity or enforceability of the
Note.

      2.7 Payment and Prepayment of Advances. The Borrowers shall pay the
principal of the Note as follows:

            (a) Maturity Date. The entire unpaid principal balance of the Note
      shall be due and payable on the Maturity Date.

            (b) Mandatory Prepayments. If at any time the aggregate outstanding
      amount of the Advances exceed the Commitment, reduced as provided in the
      definition of "Commitment" and as provided in Section 2.3, the Borrowers
      shall immediately make principal payments of such excess.

            (c) Optional Prepayments. The Borrowers may prepay the Advances, in
      whole or in part, at any time, without premium or penalty. Any such
      prepayment must be accompanied by accrued and unpaid interest on the
      amount prepaid. Each partial prepayment shall be in an amount of $100,000.

      2.8 Interest Rate Applicable to the Notes. The Borrowers will pay the Bank
interest on the unpaid principal balance of each Advance from time to time
outstanding as follows:

            (a) Before Maturity. Subject to adjustment of the rate of interest
      applicable to any given month as provided in Section 2.9 the unpaid
      principal amount of each Advance shall bear interest prior to maturity at
      a rate of 0.70% per annum.

            (b) After Maturity. Any amount of any Advances not paid when due,
      whether at the date scheduled therefor or earlier upon acceleration, shall
      bear interest until paid in full at a rate per annum equal to the Floating
      LIBOR Rate plus 2.70% per annum.

            (c) Payment of Interest. Except as provided in Section 2.9, interest
      accrued on the Notes through the last day of each calendar month shall be
      payable on the first Business Day of the next succeeding calendar month.

            (d) Computation. All interest on the Notes (including any increase
      or decreases to the rate of interest, as provided in Section 2.9) and
      interest determinations


                                       5
<PAGE>
      made for purposes of Section 2.9 shall be computed based on actual days
      elapsed in a year of 360 days.

      2.9 Adjustment to Interest Rate.

            (a) Maintenance of Balances. The Borrowers shall maintain on deposit
      in a non-interest bearing account with the Bank for each calendar month
      for which any Advance is outstanding, Average Daily Available Deposits in
      an amount (the "Required Available Deposit Amount") equal to the Average
      Daily Advance Amount for such month divided by the Average Daily Reserve
      Factor for such month.

            (b) Additional Required Balances. The Borrowers and the Bank may
      from time to time agree to reduce the interest rate on an agreed portion
      of an Advance to not less than 0.125% per annum (the mutually agreed
      reduced rate is called a "Reduced Fixed Rate"). The Borrowers agree to
      maintain on deposit in a non-interest bearing account with the Bank for
      each calendar month for which any Reduced Fixed Rate is applicable,
      Average Daily Available Deposits (the "Additional Required Available
      Deposit Amount"), in addition to those required under Section 2.9(a), in
      an amount determined in accordance with the following formula:

                  ARADA     =         ILF         x   360
                                ----------------      ---
                                  ARF  x  ECR          n

      In such formula:

            "ARADA" is the Additional Required Available Deposit Amount.

            "ARF" is the Average Daily Reserve Factor for such month

            "ECR" is the earnings credit rate per annum established by the Bank
            for non-bearing demand deposits from time to time.

            "ILF" is the interest loss factor, calculated to equal the remainder
            of (i) the amount of interest that would have accrued on the Advance
            subject to the Reduced Fixed Rate at the rate provided in Section
            2.8(a) for such month, less (ii) the amount of interest that accrued
            on the such Advance at the Reduced Fixed Rate.

            "n" is the number of days in such month.

            (c) Surpluses and Deficiencies The Bank shall determine for each
      calendar month the amount of Average Daily Available Deposits and the
      amount, if any, by which such Average Daily Available Deposits exceeds (a
      "Deposit Surplus") or is less than (a "Deposit Deficiency") the Total
      Required Deposits for such month. Any Deposit Surplus or Deposit
      Deficiency for any month will be carried forward and applied to increase
      or reduce, as the case may be, Deposit Surpluses or Deposit-Deficiencies
      determined for subsequent calendar months in the same calendar quarter.
      Unless the Bank shall otherwise agree with the Borrowers, net Deposit
      Surpluses shall not be carried forward to

                                       6
<PAGE>

      succeeding fiscal years. If a net Deposit Deficiency exists for a full
      calendar quarter, the Borrowers shall pay to the Bank additional interest
      (in addition to that paid under Section 2.8) equal to the product of (a)
      such net Deposit Deficiency, times (b) the Average Daily Floating LIBOR
      Rate for such quarter, times (c) the quotient of (i) the actual number of
      days in such quarter divided by 3, divided by (ii) 360. The Bank shall
      notify the Borrowers in writing of the amount of monthly Deposit Surpluses
      or Deficiencies and of the amount of any Deficiency Fee as soon as
      practicable after the end of each calendar quarter, and the additional
      interest within five (5) days after such notice. The Bank's written notice
      shall be presumed to be correct in the absence of manifest error.

            (c) Additional Definitions. For purposes of this Section 2.9 the
      following capitalized terms have the following meanings:

            "Available Deposits": at the time of any determination,
            interest-free collected deposit balances maintained by the Borrowers
            with the Bank which are not attributed to any other facility or
            service, in excess of those which the Bank determines to be
            necessary to support other banking services provided to the
            Borrowers and to compensate the Bank for costs of insurance of the
            Federal Deposit Insurance Corporation (or any successor), which
            services and costs are not covered by cash payments by the
            Borrowers.

            "Average Daily Available Deposits": with respect to a calendar
            month, the average daily amount of Available Deposits on deposit
            with the Bank during such calendar month.

            "Average Daily Floating LIBOR Rate": with respect to a calendar
            quarter, the average daily Floating LIBOR Rate in effect during such
            calendar quarter.

            "Average Daily Reserve Factor": with respect to any calendar month,
            the average daily amount of the Reserve Factor in effect during such
            month.

            "Average Daily Advance Amount": with respect to any calendar month,
            the total average daily unpaid principal balance of the Advances
            outstanding during such calendar month.

            "Reserve Factor": as of any date, a number equal to the number one
            (1) minus the percentage (expressed as a decimal rather than a
            percentage) stipulated by Regulation D of the Federal Reserve Board
            as the highest marginal percentage of net demand deposits required
            to be maintained on reserve by the Bank.

           "Total Required Deposits": the sum, for any calendar month, of the
           Required Available Deposit Amount and Additional Required Available
           Deposit Amount for such calendar month.

writing by an Authorized Person, the Borrowers hereby authorize the Bank, upon
receipt of telephonic instructions (confirmed in writing as soon as practicable)
from any one of the Authorized

                                       7
<PAGE>

Persons, to make Advances in the amount and type, in each case, designated by
such Authorized Person. The list of Authorized Persons may be changed by the
Borrowers at any time upon written notice to the Bank. The Bank may assume, and
act upon the assumption, that any person giving the Bank instructions hereunder
is the person he or she purports to be.

      2.11 Capital Adequacy. If the Bank shall reasonably determine that the
application or adoption of any law, rule, regulation, directive, interpretation,
treaty or guideline regarding capital adequacy, or any change therein or in the
interpretation or administration thereof, whether or not having the force of
law, increases the amount of capital required or expected to be maintained by
the Bank or any Person controlling the Bank, and such increase is based upon the
existence of the Bank's obligations hereunder and under other commitments of
this type, then from time to time, within 10 Business Days after written demand
from the Bank, the Borrowers shall pay to the Bank such amount or amounts as
will compensate the Bank or such controlling Person, as the case may be, for
such increased capital requirement. The Bank's determination of any amount to be
paid by the Borrowers under this Section shall take into consideration the
policies of the Bank or any Person controlling the Bank with respect to capital
adequacy and shall be based upon any reasonable averaging, attribution and
allocation methods. A certificate of the Bank setting forth the amount or
amounts as shall be necessary to compensate the Bank hereunder shall be deemed
conclusive in the absence of manifest error.

            (b) Any representation or warranty made or deemed to have been made
      by or on behalf of any Borrower or any Subsidiary in the Loan Documents or
      by or on behalf of any Borrower or any Subsidiary in any certificate,
      statement, report or other writing furnished by or on behalf of any

      or certified;

            (c) Any default or event of default, however denominated, shall have
      occurred and continued under the Credit Agreement; or

            (d) Any Borrower shall fail to comply with any agreement, covenant,
      condition, provision or term contained in the Loan Documents (and such

      provisions of this Section 6.1) and such failure to comply shall continue
      for 30 calendar days after notice thereof to the Borrowers by the Bank.

Default without action by the Credit Agent or lenders under the Credit Agreement
shall occur with respect to any Borrower, the Commitment shall automatically
terminate and the outstanding unpaid principal balance of the Note, the accrued

the Loan Documents shall automatically become immediately due and payable; or
(b) any other Event of Default shall occur and be continuing, then the Bank may
take any or all of the following actions: (i) declare that the Commitment is
terminated, whereupon the Commitment shall terminate, (ii) declare that the
outstanding unpaid principal balance of the Note, the accrued and unpaid
interest thereon and all other obligations of the Borrowers to the Bank under
the Loan Documents to be forthwith due and payable, whereupon the Note, all
accrued and unpaid interest thereon and all such obligations shall immediately
become due and payable, in each case without demand or notice of any kind, all
of which are hereby expressly waived, anything in this Agreement or in the Note
to the contrary notwithstanding, (iii) exercise all rights and remedies under
any other instrument, document or agreement between any Borrower and the Bank,
and (iv) enforce all rights and remedies under any applicable law.

      6.3 Offset. In addition to the remedies set forth above, upon the
occurrence of any Event of Default or at any time thereafter while such Event of
Default continues, the Bank or any other holder of the Note may offset any and
all balances, credits, deposits (general or special, time or demand, provisional
or final), accounts or monies of the Borrowers then or thereafter with the Bank
or such other holder, or any obligations of the Bank or such other holder of the
Note, against the Indebtedness then owed by the Borrowers to the Bank.

                                   ARTICLE VII
                                  MISCELLANEOUS

      7.1 Waiver and Amendment. No failure on the part of the Bank or the holder
of the Note to exercise and no delay in exercising any power or right hereunder
or under any other Loan Document shall operate as a waiver thereof; nor shall
any single or partial exercise of any power or right preclude any other or
further exercise thereof or the exercise of any other power

                                       10

or right. The remedies herein and in any other instrument, document or agreement
delivered or to be delivered to the Bank hereunder or in connection herewith are
cumulative and not exclusive of any remedies provided by law. No notice to or
demand on the Borrowers not required hereunder or under the Note shall in any
event entitle the Borrowers to any other or further notice or demand in similar
or other circumstances or constitute a waiver of the right of the Bank or the
holder of the Note to any other or further action in any circumstances without
notice or demand. No amendment, modification or waiver of any provision of the
Loan Documents or consent to any departure by any Borrower therefrom shall be
effective unless the same shall be in writing and signed by the Bank, and then
such amendment, modifications, waiver or consent shall be effective only in the
specific instances and for the specific purpose for which given.

      7.2 Expenses and Indemnities. Whether or not any Advance is made
hereunder, the Borrowers agree to reimburse the Bank upon demand for all

and/or the allocated costs of in-house counsel incurred from time to time) in
connection with the preparation, review, execution, delivery, amendment,
modification, interpretation, collection and enforcement of the Loan Documents.
The Borrowers agree to pay, and save the Bank harmless from all liability for,
any stamp or other taxes which may be payable with respect to the execution or
delivery of the Loan Documents. The Borrowers agree to indemnify and hold the
Bank harmless from any loss or expense which arises or is created by the
acceptance of telephonic or other instructions from the Borrowers for making
Advances or disbursing the proceeds thereof to the Borrowers. The obligations of
the Borrowers under this Section 7.2 shall survive any termination of this
Agreement.

      7.3 Notices. Except when telephonic notice is expressly authorized by this
Agreement, any notice or other communication to any party in connection with
this Agreement shall be in writing and shall be sent by manual delivery,
facsimile transmission, overnight courier or United States mail (postage
prepaid) addressed to such party at the address specified on the signature page
hereof, or at such other address as such party shall have specified to the other

      interest in any or all of the Advances and in all or any portion of the
      Commitment to any Person.

            (b) The Bank shall use reasonable efforts to assure that information

      shall first obtain the agreement of such prospective assignee or
      participant to comply with the provisions of Section 3(b) hereof.

      7.6 Severability. Any provision of the Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective

agrees to the terms set forth on Exhibit E hereto with respect to its Guaranteed
Obligations.

                               Opinion of Counsel


                               September ___, 2004

U.S. Bank National Association
800 Nicollet Mall
Mail Station BC-MN-H03B
Minneapolis, MN 55402
Attention: Kathleen Connor

Ladies/Gentlemen:

      This opinion is delivered to you pursuant to the Second Amended and
Restated Revolving Credit Agreement (the "Credit Agreement") dated concurrently
herewith entered into among AMERICAN HOME MORTGAGE SERVICING, INC. f/k/a
Columbia National Incorporated, and AMERICAN HOME MORTGAGE CORP. (each a
"Borrower" and collectively, the "Borrowers") and U.S. Bank National Association
(the "Bank"). Unless otherwise defined herein, capitalized terms used herein
shall have the respective meanings assigned to such terms in the Credit
Agreement.

      I am the General Counsel to the Borrowers in connection with the
preparation, execution and delivery of the Loan Documents. In that connection, I
have or a member of my staff working under by supervision has examined such
documents as I deemed necessary or appropriate for this opinion. I express no
opinion regarding any transactions or any confirmations under any of the Loan
Documents or the Loan Documents as supplemented by any transactions or
confirmations thereof.

      Based on the foregoing and upon such investigations as I have deemed
necessary, I am of the opinion that:

      1.    Each Borrower is a corporation duly organized, validly existing and
            in good standing under the laws of the state of their respective
            incorporation, and each is duly qualified and in good standing as a
            foreign corporation in all other jurisdictions in which its
            respective present operations or properties require such
            qualification.

      2.    Each Borrower has full corporate power and authority to own and
            operate its properties and assets, carry on its business as
            presently conducted, and enter into and perform its obligations
            under the Loan Documents to which it is a party.

                                       D-1
<PAGE>

      3.    The execution and delivery of the Loan Documents to which a Borrower
            is a party, the performance by such Borrower of its obligations
            thereunder, and the borrowing by such Borrower under the Credit
            Agreement, have been duly authorized by all necessary corporate
            action, and all of the Loan Documents have been duly executed and
            delivered on behalf of such Borrower and constitute valid and
            binding obligations of such Borrower, enforceable in accordance with
            their respective terms.

      4.    There is no provision in any Borrower's organizational documents,
            nor any provision in any indenture, mortgage, contract or agreement
            to which any Borrower is a party or by which it or its properties
            may be bound, nor any law, statute, rule or regulation, nor any
            writ, order or decision of any court or governmental instrumentality
            binding on such Borrower which would be contravened by the execution
            and delivery of the Loan Documents to which such Borrower is a
            party, nor do any of the foregoing prohibit such Borrower's
            performance of any term, provision, condition, covenant or any other
            obligation of such Borrower contained therein.

      5.    There are no actions, suits or proceedings pending or, to my
            knowledge after due inquiry, threatened against or affecting any
            Borrower before any court or arbitrator or by or before any
            administrative agency or government authority, which, if adversely
            determined, could constitute an Adverse Event.

      6.    Neither the making nor performance of the Loan Documents, nor the
            borrowing(s) under the Credit Agreement, requires the consent or
            approval of any governmental instrumentality.

      7.    No Borrower a "holding company", a "subsidiary company" of a
            "holding company" or an "affiliate" of a "holding company", within
            the meaning of the Public Utility Holding Company Act of 1935, as
            amended.

      8.    No Borrower is an "investment company" or a company "controlled" by
            an "investment company", within the meaning of the Investment
            Company Act of 1940, as amended.

      9.    No Borrower is engaged in the business of extending credit for the
            purpose of purchasing or carrying margin stock (within the meaning
            of Regulation U of the Board of Governors of the Federal Reserve
            System), and, to our knowledge after due inquiry, no part of the
            proceeds of any loan under the Credit Agreement will be used to
            purchase or carry any margin stock or to extend credit to others for
            the purpose of purchasing or carrying any margin stock.

      This opinion is subject to the following additional assumptions,
exceptions, qualifications and limitations:

      A. I have assumed that all parties to the Loan Documents other than the
Borrowers have all requisite power and authority to execute, deliver and perform
their respective obligations under the Loan Documents, and that the Loan
Documents have been duly authorized by all

                                       D-2
<PAGE>

necessary corporate action on the part of such parties, have been executed and
delivered by such parties and constitute the legal, valid and binding
obligations of such parties.

      B. My opinion in paragraph 3 above is subject to the qualifications that
(i) the enforceability of the Loan Documents may be limited by the effect of
laws relating to (1) bankruptcy, reorganization, insolvency, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights generally,
including, without limitation, the effect of statutory or other laws regarding
fraudulent conveyances or preferential transfers, and (2) general principles of
equity upon the specific enforceability of any of the remedies, covenants or
other provisions of the Loan Documents and upon the availability of injunctive
relief or other equitable remedies and the application of principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) as such principles relate to, limit or affect the enforcement
of creditors' rights generally and the discretion of the court before which any
proceeding for such enforcement may be brought; and (ii) I express no opinion
with respect to the validity, legality, binding effect or enforceability of
provisions for indemnification in any Loan Document to the extent such
provisions may be held to be unenforceable as contrary to public policy.

      C. I have assumed, without independent check or certification, that there
are no agreements or understandings among the Bank, the Borrowers, and any other
party which would expand, modify or otherwise affect the terms of the documents
described herein or the respective rights or obligations of the parties
thereunder.

      I am admitted to practice in the State of New York, and I render no
opinion herein as to matters involving the laws of any jurisdiction other than
the State of New York and the Federal laws of the United States of America.

      This opinion is delivered to you for your use in connection with the
Credit Agreement and may not be relied upon by any other person (other than your
participants and assignees and your bank regulators in the course of their
regulatory activities), or by you for any other purpose, without my written
consent. This opinion is given as of the date hereof, and I disclaim any
obligation to advise you of any change of law that occurs, or any facts of which
I become aware, after the date of this opinion. This opinion is limited to those
matters expressly set forth, and no opinion is to be inf red or implied beyond
the matters expressly so stated.

                                          Very truly yours,

                                                                    EXHIBIT E TO
                                                            AMENDED AND RESTATED
                                                      REVOLVING CREDIT AGREEMENT


                 TERMS WITH RESPECT TO GUARANTEED OBLIGATIONS


      If at any time determined by a court or governmental authority having
competent jurisdiction that any Borrower is liable as a guarantor (and not as a
co-obligor or co-borrower) with respect to any portion of the Obligations (with
respect to such Borrower, its "Guaranteed Obligations"), such Borrower hereby
agrees to the terms set forth herein with respect to its Guaranteed Obligations.

      1. Obligations Absolute. No act or thing need occur to establish the
liability of any Borrower for its Guaranteed Obligations, and no act or thing,
except full payment and discharge of all such Guaranteed Obligations, shall in
any way exonerate such Borrower or modify, reduce, limit or release the
liability of such Borrower for its Guaranteed Obligations. The obligations of
each Borrower for its Guaranteed Obligations shall be absolute, unconditional,
and irrevocable, and shall not be subject to any right of setoff or counterclaim
by such Borrower.

      2. Continuing Guaranty. Each Borrower shall be liable for its Guaranteed
Obligations, plus accrued interest thereon and all attorneys' fees, collection
costs and enforcement expenses referable thereto. Guaranteed Obligations may be
created and continued in any amount without affecting or impairing the liability
of such Borrower therefor. No notice of such Guaranteed Obligations already or
hereafter contracted or acquired by the Bank, or any renewal or extension of any
thereof need be given to such Borrower and none of the foregoing acts shall
release such Borrower from liability hereunder. The agreement of each Borrower
pursuant to the Loan Agreement with respect to its Guaranteed Obligations is an
absolute, unconditional and continuing guaranty of payment of such Guaranteed
Obligations and shall continue to be in force and be binding upon such Borrower
until such Guaranteed Obligations are paid in full and the Credit Agreement is
terminated, and the Bank may continue, at any time and without notice to such
Borrower, to extend credit or other financial accommodations and loan monies to
or for the benefit of the other Borrower on the faith thereof. Each Borrower
hereby waives, to the fullest extent permitted by law, any right they may have
to revoke or terminate its guaranty of the Guaranteed Obligations before the
Guaranteed Obligations are paid in full and the Loan Agreement is terminated. In
the event any Borrower shall have any right under applicable law to otherwise
terminate or revoke its guaranty of the Guaranteed Obligations which cannot be
waived, such termination or revocation shall not be effective until written
notice of such termination or revocation, signed by such Borrower, is actually
received by the Bank's officer responsible for such matters. Any notice of
termination or revocation described above shall not affect such Borrower's
guaranty of the Guaranteed Obligations in relation to (i) any of the Guaranteed
Obligations that arose prior to receipt thereof or (ii) any of the Guaranteed
Obligations created after receipt thereof, if such Guaranteed Obligations were
incurred either through loans by the Bank or letters of credit issued or
arranged for by Bank, including, without limitation, advances, readvances or
letters of credit in an aggregate outstanding amount not to exceed the aggregate
amount of the Commitments as of the time such notice of termination or


                                       E-1
<PAGE>

revocation was received, and/or for the purpose of protecting any collateral,
including, but not limited, to all protective advances, costs, expenses, and
attorneys' and paralegals' fees, whensoever made, advanced or incurred by the
Bank in connection with the Guaranteed Obligations. If, in reliance on any
Borrower's guaranty of its Guaranteed Obligations, the Bank makes loans or other
advances to or for the benefit of any other Borrower or takes other action under
this Agreement after such aforesaid termination or revocation by the undersigned
but prior to the receipt by the Bank of said written notice as set forth above,
the rights of the Bank shall be the same as if such termination or revocation
had not occurred.

      3. Other Transactions. Whether or not any existing relationship between
the Borrowers has been changed or ended, the Bank may, but shall not be
obligated to, enter into transactions resulting in the creation or continuance
of other obligations of any Borrower to the Bank, without consent or approval by
the other Borrowers and without notice to the other Borrowers, and all such
obligations shall be guaranteed by virtue of the Credit Agreement. The liability
of each Borrower under the Loan Agreement with respect to the Guaranteed
Obligations shall not be affected or impaired by any of the following acts or
things (which the Bank is expressly authorized to do, omit or suffer from time
to time, without notice to or approval by any Borrower): (i) any acceptance of
collateral security, other guarantors, accommodation parties or sureties for any
or all Guaranteed Obligations; (ii) any one or more extensions or renewals of
Guaranteed Obligations (whether or not for longer than the original period) or
any modification of the interest rates, maturities or other contractual terms
applicable to any Guaranteed Obligations; (iii) any waiver or indulgence granted
to any other Borrower, any delay or lack of diligence in the enforcement of
Guaranteed Obligations, or any failure to institute proceedings, file a claim,
give any required notices or otherwise protect any Guaranteed Obligations; (iv)
any full or partial release of, settlement with, or agreement not to sue, any
other Borrower or any other guarantor or other person liable in respect of any
Guaranteed Obligations; (v) any discharge of any evidence of Guaranteed
Obligations or the acceptance of any instrument in renewal thereof or
substitution therefor; (vi) any failure to obtain collateral security for
Guaranteed Obligations, or to see to the proper or sufficient creation and
perfection thereof, or to establish the priority thereof, or to protect, ensure,
or enforce any collateral security, or any modification, substitution,
discharge, impairment or loss of any collateral security; (vii) any foreclosure
or enforcement of any collateral security; (viii) any transfer of any Guaranteed
Obligations or any evidence thereof; (ix) any order of application of any
payments or credits upon Guaranteed Obligations; (x) any release of any
collateral security for Guaranteed Obligations; (xi) any amendment to or
modification of, any agreement between the Bank and any other Borrower, or any
waiver of compliance by any other Borrower with the terms thereof; and (xii) any
election by the Lender under Section 1111 (b) of the United States Bankruptcy
Code.

      4. Waivers of Defenses and Rights. Each Borrower waives any and all
defenses, claims and discharges of any other Borrower, or any other obligor,
pertaining to the Guaranteed Obligations, except the defense of discharge by
payment in full. Without limiting the generality of the foregoing, no Borrower
will assert, plead or enforce against the Bank any defense of waiver, release,
discharge in bankruptcy, statute of limitations, res judicata, statute of
frauds, anti-deficiency statute, fraud, usury, illegality or unenforceability
which may be available to the other Borrower or any other person liable in
respect of any Guaranteed Obligations, or any setoff available against the Bank
to any other Borrower or any such other person, whether or not on account of a
related transaction. Each Borrower expressly agrees that such Borrower shall be


                                       E-2
<PAGE>

and remain liable for any deficiency remaining after foreclosure of any mortgage
or security interest securing Guaranteed Obligations, whether or not the
liability of or any other obligor for such deficiency is discharged pursuant to
statute, judicial decision or contract. Each Borrower waives presentment, demand
for payment, notice of dishonor or nonpayment, and protest of any instrument
evidencing Guaranteed Obligations. Each Borrower agrees that its liability under
the Loan Agreement for the Guaranteed Obligations shall be primary and direct,
and that the Bank shall not be required first to resort for payment of the
Guaranteed Obligations to any other Borrower or other persons or their
properties, or first to enforce, realize upon or exhaust any collateral security
for the Guaranteed Obligations, or to commence any action or obtain any judgment
against any other Borrower or against any such collateral security or to pursue
any other right or remedy the Bank may have against any other Borrower before
enforcing the liability of such Borrower for the Guaranteed Obligations under
the Loan Agreement.

      5. Approval of Credit. Each Borrower has, independently and without
reliance upon the Bank or their respective directors, officers, agents or
employees, and instead in reliance upon information furnished by the other
Borrowers and upon such other information as such Borrower deemed appropriate,
made its own independent credit analysis and decision to guaranty the
obligations of the other Borrowers pursuant to the Loan Agreement.

      6. Waiver of Subrogation. Each Borrower expressly waives any and all
rights of subrogation, reimbursement, indemnity, exoneration, contribution or
any other claim which it may now or hereafter have against any other Borrower,
any endorser or any other guarantor of all or any part of the Guaranteed
Obligations, and each Borrower hereby waives any benefit of, and any right to
participate in, any security or collateral given to the Bank to secure payment
of the Guaranteed Obligations or any other liability of any other Borrower to
the Bank. Each Borrower further agrees that any and all claims it may have
against any other Borrower, any endorser or any other guarantor of all or any
part of the Guaranteed Obligations or against any of their respective
properties, whether arising by reason of any payment by such Borrower to the
Lender pursuant to the provisions hereof or otherwise, is hereby waived.
