                        ---------
         all extensions, renewals and modifications of the Note and all
         substitutions therefor. All terms and provisions of the Note are hereby
         incorporated herein.

               2.4  Interest.
                    --------

                    2.4(a) Except as otherwise provided in Section 0 hereof, the
               unpaid amount of each Advance against an Eligible Loan shall bear
               interest, from the date the Advance until paid in full, at the
               rate(s) per annum set forth on Exhibit M attached hereto and made
                                              ---------
               a part hereof.

                    2.4(b) Provided no Default or Event of Default exists, the
               Borrowers are entitled to receive a benefit in the form of an
               "Earnings Credit" on the portion of the Eligible Balances
               maintained in time deposit accounts with a Designated Bank, and
               the Borrowers are entitled to receive a benefit in the form of an
               "Earnings Allowance" on the portion of the Eligible Balances
               maintained in demand deposit accounts with a Designated Bank. Any
               Earnings Allowance shall be used

                                      20

               Charges and fees, including, but not limited to Commitment Fees,
               Non-Usage Fees and Warehousing Fees, and may be used, at the
               Lender's option, to reduce accrued interest. Any Earnings
               Allowance not used during the month in which the benefit was
               received shall be accumulated for use and must be used within 6
               months of the month in which the benefit was received. Provided
               no Default or Event of Default exists, any Earnings Credit not
               used during the month in which the benefit was received shall be
               used to provide a cash benefit to the Borrowers. Any Earnings
               Credit retained by the Lender as a result of a Default or Event
               of Default will be applied to the payment of the Borrowers'
               Obligations in such order as the Lender will determine in its
               sole discretion. The Lender's determination of the Earnings
               Credit and the Earnings Allowance for any month shall be
               determined by the Lender in its sole discretion and shall be
               conclusive and binding absent manifest error. In no event shall
               the benefit received by the Borrowers exceed the Depository
               Benefit.

                    Either party hereto may terminate the benefits provided for
               in this Section effective immediately upon Notice to the other
               party, if the terminating party shall have determined (which
               determination shall be conclusive and binding absent manifest
               error) at any time that any applicable law, rule, regulation,
               order or decree or any interpretation or administration thereof
               by any governmental authority charged with the interpretation or
               administration thereof, or compliance by such party with any
               request or directive (whether or not having the force of law) of
               any such authority, shall make it unlawful or impossible for such
               party to continue to offer or receive the benefits provided for
               in this Section. No Notice is required for a termination of
               benefits as a result of a Default or Event of Default.

                    2.4(c) Interest shall be computed on the basis of a 360-day
               year and applied to the actual number of

                                      21

               days elapsed in each interest calculation period and shall be
               payable monthly in arrears, on the first day of each month,
               commencing with the first month following the Closing Date and on
               the Maturity Date.

                    2.4(d) If, for any reason, no interest is due on an Advance,
               the Borrowers agree to pay to the Lender an administrative fee
               equal to one day of interest on such Advance at the rate of
               interest applicable to such Advance, as in effect on the date of
               such Advance. Administrative and other fees shall be due and
               payable in the same manner as interest is due and payable
               hereunder.

                    2.4(e) Upon Notice to the Borrowers, after the occurrence
               and during the continuation of an Event of Default, the unpaid
               amount of each Advance shall bear interest until paid in full at
               a per annum rate of interest (the "Default Rate") equal to 4% in
               excess of the rate of interest otherwise applicable to the
               Advance or, if no rate is applicable, the highest rate then
               applicable to any outstanding Advances.

                    2.4(f) The floating rates of interest provided for in this
               Agreement will be adjusted as of the effective date of each
               change in the applicable index. The Lender's determination of
               such rates as of any date of determination shall be conclusive
               and binding, absent manifest error.

               2.5  Principal Payments

               necessity of prior demand or notice from the Lender, and the
               Borrowers authorize the Lender to cause

                    thereby was not delivered under the Purchase Commitment
                    prior to such

                    mandatory delivery date, or the Purchase Commitment is
                    terminated; unless in each case, such Pledged Mortgage or
                    Pledged Security is eligible for delivery to an Investor
                    under a comparable Purchase Commitment acceptable to the
                    Lender.

                         (7)  Upon sale or other disposition of the Pledged
                    Mortgage or, if a Pledged Mortgage is included in an
                    Eligible Mortgage Pool, upon sale or other disposition of
                    the related Agency Security.

                    2.5(d) Upon Notice to the Borrowers by the Lender, the
               Borrowers shall pay to the Lender, and the Borrowers authorize
               the Lender to cause the Funding Bank to charge the Borrowers'
               Operating Account for, the amount of any outstanding Advance
               against a specific Pledged Mortgage upon the earliest occurrence
               of any of the following events:

                         (1)  For any Pledged Mortgage, the Warehouse Period
                    elapses.

                         (2)  On the date the payment of a Lien senior to a
                    Pledged Mortgage is delinquent for a period of 60 days.

                         (3)  Forty-five days elapse from the date the Pledged
                    Mortgage was delivered to an Investor or an Approved
                    Custodian for examination and purchase or inclusion in a
                    Mortgage Pool, without the purchase being made or an
                    Eligible Mortgage Pool being initially certified, or upon
                    the second rejection of the Pledged Mortgage as
                    unsatisfactory by an Investor or an Approved Custodian.

                         (4)  Seven Business Days elapse from the date a Wet
                    Settlement Advance was made without receipt by the Lender of
                    all Collateral Documents relating to such Pledged Mortgage,
                    or such Collateral Documents, upon examination by the
                    Lender, are found not to be in compliance with the
                    requirements of this Agreement or the related Purchase
                    Commitment, if any.

<PAGE>

                         (5)  With respect to any Pledged Mortgage, any of the
                    items described in Section 2.2(d), upon examination by the
                    Lender, are found not to be in compliance with the
                    requirements of this Agreement or the related Purchase
                    Commitment, if any.

                         (6)  If 3 Business Days have elapsed since Lender
                    shipped a Pledged Mortgage, pursuant to Exhibit D, to a
                                                            ---------
                    Person other than an Investor or an Approved Custodian, and
                    Lender has not received payment of the Release Amount.

                    2.5(e)  The outstanding amount of any Advance made pursuant
               to Section 0 shall be payable in full within 1 Business Day after
               the date of such Advance.

                    2.5(f)  In addition to the payments required pursuant to
               Sections 2.5(d) and 2.5(e), if the principal amount of any
               Pledged Mortgage is prepaid in whole or in part while an Advance
               is outstanding against such Pledged Mortgage, the Borrowers shall
               be obligated to pay to the Lender, without the necessity of prior
               demand or notice from the Lender, and the Borrowers authorize the
               Lender to cause the Funding Bank to charge the Borrowers'
               Operating Account for the amount of such prepayment, to be
               applied to such Advance.

                    2.5(g) The proceeds of the sale or other disposition of
               Pledged Mortgages and Pledged Securities shall be paid directly
               by the Investor to the Cash Collateral Account. The Borrowers
               shall give Notice to the Lender (telephonically, to be followed
               by written notice) of the Pledged Mortgages or Pledged Securities
               for which proceeds have been received. Upon receipt of such
               Notice the Advances against such Pledged Mortgages or Pledged
               Securities shall be repaid from such proceeds and such Pledged
               Mortgages or Pledged Securities shall be considered to have been
               redeemed from pledge. The Lender is entitled to rely upon the
               Borrowers' affirmation that deposits in the Cash Collateral
               Account represent payment from Investors for the purchase of
               Pledged Mortgages or Pledged Securities as specified by

                                      25
<PAGE>

               the Borrowers. In the event that the payment from an Investor for
               the purchase of Pledged Mortgages or Pledged Securities is less
               than the outstanding Advances against such Pledged Mortgages or
               the Mortgage Loans backing Pledged Securities, the Lender is
               authorized to cause the Funding Bank to charge the Borrowers'
               Operating Account for an amount equal to such deficiency.
               Provided no Default or Event of Default exists, the Lender shall
               return any excess payment from an Investor for Pledged Mortgages
               or Pledged Securities to the Borrowers.

                    2.5(h) The Borrowers may, from time to time, prepay a
               portion of the Advances pursuant to this Section 0 (any such
               prepayment is hereafter referred to as a "Buydown"). A Buydown
               shall not, except as set forth below, be deemed a prepayment of
               any particular Advances or of the Advances to a particular
               Borrower, and shall not entitle any Borrower to the release of
               any Collateral, but the Buydown shall be considered generally to
               be a reduction in the amount of Advances outstanding under this
               Agreement. Any Borrower may reborrow all or any portion of a
               Buydown, whether or not the Buydown was made by that Borrower,
               provided no Default or Event of Default has occurred and is
               continuing, upon written notice to the Lender that the Borrower
               desires to reborrow such amount. In the event the Lender receives
               a payment of Advances that would, as a result of the Buydown,
               reduce the outstanding principal balance of the Advances to an
               amount less than zero, the Buydowns, or a portion thereof equal
               to such excess, shall be re-advanced to any Borrower. The Lender
               may apply the Buydown to reduce the interest on any outstanding
               Advances that it chooses, in its sole and absolute discretion.

               2.6  Expiration of Commitment. The Commitment shall expire on the
                    ------------------------
          Maturity Date.

               2.7  Method of Making Payments.
                    -------------------------

                                      26
<PAGE>

               2.7(a) Except as otherwise specifically provided herein, all
          payments hereunder shall be made to the Lender not later than the
          close of business on the date when due unless such date is a non-
          Business Day, in which case, such payment shall be due on the first
          Business Day thereafter, and shall be made in lawful money of the
          United States of America in immediately available funds transferred
          via wire to accounts designated by the Lender from time to time.

               2.7(b) After the occurrence and during the continuance of an
          Event of Default, and without the necessity of prior demand or notice
          from the Lender, the Borrowers authorize the Lender to cause the
          Funding Bank to charge the Borrowers' Operating Account for any
          Obligations due and owing the Lender.

          2.8  Commitment Fees and Non-Usage Fees.
               ----------------------------------

               2.8(a) The Borrowers agree to pay to the Lender a Commitment Fee
         in the amount of one-eighth percent (1/8%) per annum of the Commitment
         Amount which Commitment Fee shall be paid quarterly in advance and
         shall be computed on the basis of a 365-day year and applied to the
         actual number of days elapsed in such Calendar Quarter. On the Closing
         Date, the Borrowers shall pay the prorated portion of the quarterly
         Commitment Fee due from the Closing Date to the last day of the current
         Calendar Quarter. Thereafter, the Borrowers shall make quarterly
         payments of the Commitment Fee on the first (1st) day of each Calendar
         Quarter. If the Maturity Date is other than the last day of a Calendar
         Quarter, the Borrowers shall pay the prorated portion of the quarterly
         Commitment Fee due from the beginning of the then current Calendar
         Quarter to and including the Maturity Date. If, at any time during a
         Calendar Quarter, the Commitment Amount is increased, on the first
         (1st) day of the next succeeding Calendar Quarter the Borrowers shall
         pay an additional Commitment Fee in the amount of one-eighth percent
         (1/8%) per annum of the increased Commitment Amount from the date of
         the increase to the end of the preceding

                                      27
<PAGE>

          Calendar Quarter. The Borrowers shall not be entitled to a reduction
          in the amount of the Commitment Fee, in the event the Commitment
          Amount is reduced or in the event that the Commitment is terminated at
          the request of the Borrowers or as a result of an Event of Default. If
          the Commitment terminates at the request of the Borrowers or as a
          result of an Event of Default, the unpaid balance of the Commitment
          Fee shall be due and payable in full on the date of such termination.

               2.8(b) At the end of each Calendar Quarter, during the term
          hereof commencing with the Calendar Quarter beginning on April 1,
          2000, the Lender shall determine the average usage of the Commitment
          by calculating the arithmetic daily average of the Advances
          outstanding during such Calendar Quarter. The Lender shall then
          subtract such quarterly average usage (the "Used Portion") from the
          arithmetic daily average of the Commitment Amount (and the result
          thereof shall be known as the "Unused Portion"). If the Unused Portion
          is greater than 50% of the Commitment Amount, the Borrowers shall pay
          in arrears, within 30 days after the end of each Calendar Quarter, a
          Non-Usage Fee (the "Non-Usage Fee") equal to one-eighth percent (1/8%)
          per annum on the total amount of the Unused Portion of the Commitment
          during such Calendar Quarter. If the Maturity Date of the Commitment
          is other than the last day of a Calendar Quarter, the Borrowers shall
          pay the prorated portion of the quarterly Non-Usage Fee due from the
          beginning of the then current Calendar Quarter to and including the
          Maturity Date. In the absence of manifest error, the calculation by
          the Lender of the amount of any Non-Usage Fee shall be conclusive. If
          the Commitment terminates at the request of the Borrowers or as a
          result of an Event of Default, the Non-Usage Fee shall be due and
          owing through the last day of the current Calendar Quarter.

          2.9  Warehousing Fees.  The Borrowers agree, at the time of each
               ----------------
     Advance, to pay to the Lender a Warehousing Fee in the amount of $20.00 for
     each Mortgage Loan pledged as Collateral for such Advance. Warehousing Fees
     are due when incurred, but shall not be

                                      28
<PAGE>

     delinquent if paid within 15 days after receipt of an invoice or an account
     analysis statement from the Lender.

          2.10  Miscellaneous Charges. The Borrowers agree to reimburse the
                ---------------------
     Lender for miscellaneous charges and expenses (collectively, "Miscellaneous
     Charges") incurred by or on behalf of the Lender in connection with the
     handling and administration of Advances, and to reimburse the Lender for
     Miscellaneous Charges incurred by or on behalf of the Lender in connection
     with the handling and administration of the Collateral. For the purposes
     hereof, Miscellaneous Charges shall include, but not be limited to, costs
     for UCC, tax lien and judgment searches conducted by the Lender, filing
     fees, charges for wire transfers, check processing charges, charges for
     security delivery fees, charges for overnight delivery of Collateral to
     Investors, the Funding Bank's service fees and overdraft charges and
     Designated Bank Charges. Miscellaneous Charges are due when incurred, but
     shall not be delinquent if paid within 15 days after receipt of an invoice
     or an account analysis statement from the Lender.

          2.11 Interest Limitation. All agreements between the Borrowers and the
               -------------------
     Lender are hereby expressly limited so that in no contingency or event
     whatsoever, whether by reason of acceleration of maturity of this Agreement
     or the Note or otherwise, shall the amount paid or agreed to be paid to the
     Lender for the use, forbearance, loaning or retention of the Advances
     secured by this Agreement exceed the maximum permissible under applicable
     law. If from any circumstances whatsoever, fulfillment of any provisions
     hereof or of the Note, or any other document securing this Agreement at any
     time given shall involve transcending the limit of validity prescribed by
     law, then, the obligation to be fulfilled shall automatically be reduced to
     the limit of such validity, and if from any circumstances the Lender should
     ever receive as interest an amount which would exceed the highest lawful
     rate of interest, such amount which would be in excess of interest shall be
     applied to the reduction of the principal balance secured by the Note and
     not to the payment of interest thereunder. This provision shall control
     every other provision of all agreements between the Borrowers and Lender

                                      29
<PAGE>

     and shall also be binding upon and available to any subsequent holder of
     the Note.

          2.12  Increased Costs; Capital Requirements. In the event any
                -------------------------------------
     applicable law, order, regulation or directive issued by any governmental
     or monetary authority, or any change therein or in the governmental or
     judicial interpretation or application thereof, or compliance by the Lender
     with any request or directive (whether or not having the force of law) by
     any governmental or monetary authority:

                2.12(a) Does or shall subject the Lender to any tax of any kind
          whatsoever with respect to this Agreement or any Advances made
          hereunder, or change the basis of taxation on payments to the Lender
          of principal, fees, interest or any other amount payable hereunder
          (except for change in the rate of tax on the overall gross or net
          income of the Lender by the jurisdiction in which the Lender's
          principal office is located);

                2.12(b) Does or shall impose, modify or hold applicable any
          reserve, capital requirement, special deposit, compulsory loan or
          similar requirement against assets held by, or deposits or other
          liabilities in or for the account of, advances or loans by, or other
          credit extended by, or any other acquisition of funds by, any office
          of the Lender which are not otherwise included in the determination of
          the interest rate as calculated hereunder;

     and the result of any of the foregoing is to increase the cost to the
     Lender of making, renewing or maintaining any Advance or to reduce any
     amount receivable in respect thereof or to reduce the rate of return on the
     capital of the Lender or any Person controlling the Lender as it relates to
     credit facilities in the nature of that evidenced by this Agreement, then,
     in any such case, the Borrowers shall promptly pay any additional amounts
     necessary to compensate the Lender for such additional cost or reduced
     amounts receivable or reduced rate of return as determined by the Lender
     with respect to this Agreement or Advances made

                                      30
<PAGE>

          hereunder. If the Lender becomes entitled to claim any additional
          amounts pursuant to this Section, it shall notify the Borrowers of the
          event by reason of which it has become so entitled and the Borrowers
          shall pay such amount within 15 days thereafter. A certificate as to
          any additional amount payable pursuant to the foregoing sentence
          containing the calculation thereof in reasonable detail submitted by
          the Lender to the Borrowers shall be conclusive in the absence of
          manifest error. The obligations of the Borrowers under this Section
          shall survive the payment of all other Obligations and the termination
          of this Agreement.

     3.   COLLATERAL.

               3.1  Grant of Security Interest. As security for the payment of
                    ---------------------------
          the Note and for the performance of all of the Obligations, each of
          the Borrowers hereby assigns and transfers to the Lender all right,

               Mortgages evidencing or securing such Mortgage Loans, which from
               time to time are delivered or caused to be delivered to the

               without limitation all Mortgage Loans in respect of which Wet

               otherwise in the possession of the Lender or its agent, bailee or
               custodian as assignee for the Lender's benefit, or pledged to the
               Lender, or for such purpose are registered by book-entry in the

               which from time to time an Advance has been made by the Lender
               hereunder (the "Pledged Securities").

                    3.1(c) All private mortgage insurance and all commitments

               Security is issued:

                    (1)  The Borrowers are in Default under this Agreement;

                    (2)  The Lender's security interest in the Pledged Mortgages
               is not released;

                    (3)  Borrowers hereby grant Lender a security interest in
               the Mortgage-backed Security, effective immediately upon its
               issuance, making it a Pledged Security hereunder; and

                    (4)  The Lender shall be entitled to possession of such
               Pledged Security in the manner provided below.

               3.2(c)    If Pledged Mortgages are transferred to an Approved

          Mortgage Pool shall be released upon the issuance of the Agency

          interest in such Pledged Security shall be released only against
          payment to the Lender of the Release Amount in connection with the
          Pledged Mortgages backing such Pledged Security. The Lender shall be
          entitled to possession of such Pledged Security in the manner provided
          below.

               3.2(d)    The Lender shall have the exclusive right to the

          securities intermediary (as such term is defined in the Uniform
          Commercial Code of Minnesota) in an account containing only customer
          securities and credited to an account of the Lender. The Lender shall
          have the right to cause delivery of the Pledged Securities to be made
          to the Investor or the Pledged Securities credited to the account of
          the Investor or the Investor's designee only against payment

                                      34

          which such Pledged Securities are registered in the name of such
          financial institution, as agent or securities intermediary for the
          Lender, and the Borrowers agree upon request of the Lender to execute
          and deliver to such other financial institutions the Borrowers'
          written concurrence in any such standing arrangements.

               3.2(e) Prior to the occurrence of an Event of Default, a Borrower
          may redeem a Pledged Mortgage or Pledged Security from the Lender's
          security interest by notifying the Lender of its intention to redeem
          such Pledged Mortgage or Pledged Security from pledge and either (a)
          paying, or causing an Investor to pay, to the Lender, for application
          to prepayment of the principal balance of the Note, the Release Amount
          in connection with such Pledged Mortgage or Pledged Security, or (b)
          delivering substitute Collateral which, in addition to being
          acceptable to the Lender in its sole discretion will, when included
          with the Collateral, result in a Collateral Value of all Collateral
          held by the Lender which is at least equal to the aggregate
          outstanding Advances.

               3.2(f) Following the occurrence of a Default or Event of Default,
          the Lender may, with no liability to the Borrowers or any Person,
          continue to release its security interest in any Pledged Mortgage or
          Pledged Security against payment of the Release Amount in connection
          with such Pledged Mortgage or Pledged Security.

               3.2(g) The amount (the "Release Amount") to be paid by the
          Borrowers to obtain the release of the Lender's security interest in a
          Pledged Mortgage shall be (i) prior to the occurrence of an Event of
          Default, the principal amount of the Advances outstanding against such
          Pledged Mortgage, and (ii) from and after the

               Committed Purchase Price of such Pledged Mortgage or, if there is
               no Purchase Commitment therefor, the amount paid to the Lender in
               a commercially reasonable disposition thereof.

               3.3 Delivery of Additional Collateral or Mandatory Prepayment.
                   ---------------------------------------------------------
          At any time that the aggregate Collateral Value of the Collateral then
          pledged hereunder is less than the aggregate amount of the Advances
          then outstanding hereunder, the Lender may request, and the Borrowers
          shall within 2 Business Days after Notice by the Lender (a) deliver to
          the Lender for pledge hereunder additional Collateral, with a
          Collateral Value sufficient to cover the difference between the
          Collateral Value of the Collateral pledged and the aggregate amount of
          Advances outstanding hereunder, and/or (b) repay the Advances in an
          amount sufficient to reduce the aggregate balance thereof outstanding
          to or below the Collateral Value of the Collateral pledged hereunder.

               3.4 Release of Collateral.
                   ---------------------

               Default, upon delivery by the Borrowers to the Lender of shipping
               instructions pursuant to Exhibit D-SF, the Lender will transmit
                                        ------------
               Pledged Mortgages or Pledged Securities and all related loan
               documents or pool documents to the applicable Investor, Approved
               Custodian or other party.

                   3.4(c) Upon receipt of Notice from the Borrowers under
               Section 0 hereof, and repayment of the Release Amount with
               respect to a Pledged Mortgage identified by the Borrowers, any
               Collateral Documents relating to the redeemed Pledged Mortgage or
               Mortgage Loan backing a Pledged Security which have not been

               by the Lender to the Borrowers.

               3.5 Collection and Servicing Rights. So long as no Event of
                   -------------------------------
         Default shall have occurred and be continuing, the Borrowers shall be
         entitled to service and receive and collect directly all sums payable
         to the Borrowers in respect of the Collateral other than proceeds of
         any Purchase Commitment or proceeds of the sale of any Collateral.
         Following the occurrence of any Event of Default, the Lender or its
         designee shall thereafter be entitled to service and receive and
         collect all sums payable to the Borrowers in respect of the Collateral,
         and in such case (a) the Lender or its designee in its discretion may,
         in its own name, in the name of the Borrowers or otherwise, demand, sue
         for, collect or receive any money or property at any time payable or
         receivable on account of or in exchange for any of the Collateral, but
         shall be under no obligation to do so, (b) the Borrowers shall, if the
         Lender so requests, hold in trust for the benefit of the Lender and
         forthwith pay to the Lender at its office designated by Notice

         respect of any of the Collateral, advising the Lender as to the source
         of such funds, and (c) all amounts so received and collected by the
         Lender shall be held by it as part of the Collateral.

         Commitment shall have expired or been terminated, and (b) no Advances,
         interest or other Obligations shall be outstanding and unpaid, the
         Lender shall deliver or release its security interest and shall deliver
         all Collateral in its possession to the Borrowers at the Borrowers'
         expense. The receipt of the Borrowers for any Collateral released or
         delivered to the Borrowers pursuant to any provision of this Agreement
         shall be a complete and full acquittance for the Collateral so
         returned, and the Lender shall thereafter be discharged from any
         liability or responsibility therefor.

             3.7 Transfers of Pledged Mortgages Between Borrowers. So long as

<PAGE>

     Default, and so long as the Lender has actual physical possession of all
     documents that were required to be delivered under the appropriate Exhibit
                                                                        -------
     D (including the original Mortgage Note), any Borrower may assign its
     -
     rights in a Pledged Mortgage to any other Borrower without repaying the
     Advance outstanding against it, in the following manner:

               3.7(a)  The assignment shall not cause the Borrowers to be
          otherwise in violation of this Agreement.

               3.7(b)  If the Borrower is assigning all of its right, title and
          interest in the Pledged Mortgage to another Borrower, or the assignee
          Borrower is intended to become the legal owner of the Mortgage Note,
          then the Borrowers shall give the Lender prior Notice of the proposed
          assignment, and along with that Notice, shall send the Lender all of
          the following documents:

                   (1)  A detailed schedule, describing the loans to be assigned
               from that assignor Borrower to that assignee Borrower.

                   (2)  An allonge to the Mortgage Note, signed by the assignee
               Borrower, endorsing the Mortgage Note in blank.

                   (3)  A copy of the recorded assignment (or the assignment, as
               sent for recording) of the Mortgage to the assignee Borrower.

                   (4)  An unrecorded assignment of the Mortgage from the
               assignee Borrower to the Lender.

          If all of the documents meet with the approval of Lender (which may
          withhold its approval for any reason or for no reason), the Lender
          shall fill in the Mortgage Note's previous blank endorsement (the
          blank endorsement from the assignor Borrower that was given to the
          Lender at the time that the Pledged Mortgage was pledged or previously
          assigned under this Section 0) in the name of the assignee Borrower.

               3.7(c)  Any assignment under this Section 0 shall be subject to
          Lender's security interest in that Pledged Mortgage and all related
          rights that are assigned.

               3.7(d)  The assignment of Pledged Mortgages is intended not to
          have any effect on the expiration of the applicable Warehouse Period
          or other time-related provisions. Therefore, any Advance outstanding
          against a Pledged Mortgage that is assigned under this Section 0 shall
          be deemed to have been made at the time that the Advance was made to
          the assignor Borrower (or the initial assignor Borrower, if more than
          one assignment under this Section 0 has taken place). Similarly, the
          pledge of the Pledged Mortgage shall be deemed to have taken place
          when the assignor Borrower (or the initial Borrower) pledged the
          Pledged Mortgage.

     hereby represent and warrant to the Lender, as of the date of this

               5.15(a) The Borrowers are the legal and equitable owner and
          holder, free and clear of all Liens (other than Liens granted
          hereunder), of the Pledged Mortgages and the Pledged Securities. All

          right, power and authority to pledge the Collateral pledged and to be
          pledged by it hereunder.

               5.15(c) Any Mortgage Loan and any related document included in

          Association form or equivalent thereof, from a recognized title
          insurance company, insuring the priority of the Lien of the Mortgage
          and meeting the

                                      53
<PAGE>

          usual requirements of Investors purchasing such Mortgage Loans.

               5.15(d) No default has occurred and is continuing for more than
          60 days under any Mortgage Loan included in the Pledged Mortgages
          without the Advance against such Pledged Mortgage having been repaid
          in accordance with Section 0 hereof, provided, however, that with
          respect to Pledged Mortgages which have already been pledged as

          promptly notify the Lender.

          Mortgage Loan, and such insurance or guarantee is and will continue to
          be in full force and effect.

               5.15(f) All fire and casualty policies covering the premises
          encumbered by each Mortgage included in the Pledged Mortgages (1) name
          and will continue to name the Borrowers and their successors and
          assigns as the insured under a standard mortgagee clause, (2) are and
          will continue to be in full force and effect, and (3) afford and will
          continue to afford insurance against fire and such other risks as are
          usually insured against in the broad form of extended coverage
          insurance from time to time available.

               5.15(g) Pledged Mortgages secured by premises located in a
          special flood hazard area designated as such by the Director of the

          Program.

               5.15(h) Each Pledged Mortgage, against which an Advance is made
          on the basis of a Purchase Commitment, meets all requirements of such
          Purchase Commitment. The

                                      54
<PAGE>

          Borrowers shall assure that Pledged Mortgages which are intended to be
          used in the formation of Mortgage-backed Securities shall comply or,
          prior to the formation of any such Mortgage-backed Security, shall
          comply with the requirements of the governmental instrumentality,
          department, agency or other Person issuing or guaranteeing such
          Mortgage-backed Security. The Borrowers shall assure that Uncommitted
          Mortgage Loans pledged hereunder meet all requirements of one or more
          Investors with which the Borrowers have agreements or other
          arrangements to sell similar Mortgage Loans.

               5.15(i) For Pledged Mortgages which will be used to back Ginnie
          Mae Mortgage-backed Securities, the Borrowers have received from
          Ginnie Mae a Confirmation Notice or Confirmation Notices for Request
          Additional Commitment Authority and for Request Pool Numbers, and
          there remains available thereunder a commitment on the part of Ginnie
          Mae sufficient to permit the issuance of Ginnie Mae Mortgage-backed
          Securities in an amount at least equal to the amount of such Pledged
          Mortgages designated by the Borrowers as the Mortgage Loans to be used
          to back such Ginnie Mae Mortgage-backed Securities; each such
          Confirmation Notice is in full force and effect; each of such Pledged
          Mortgages has been assigned by the Borrowers to one of such Pool
          Numbers and a portion of the available Ginnie Mae Commitment has been
          allocated thereto by the Borrowers, in an amount at least equal to
          such Pledged Mortgages; and each such assignment and allocation has
          been reflected in the books and records of the Borrowers.

               5.15(j) Each Pledged Mortgage secured by real property to which a
          Manufactured Home is affixed will create a valid Lien on such
          Manufactured Home that will have priority over any other Lien on such
          Manufactured Home, whether or not arising under applicable real
          property law.

          5.16 Servicing. Attached hereto as Exhibit E is a true and complete
               ---------                     ---------

     Contracts are in full force and effect and, except as

                                      55
<PAGE>

     otherwise indicated, are unencumbered by Liens. No default or event which,
     with notice or lapse of time or both, would become a default, exists under
     any such Servicing Contract.

          5.17 No Adverse Selection. The Borrowers have not selected the
               ---------------------
     Collateral in a manner so as to affect adversely the Lender's interests.

          5.18 Year 2000 Compliance. Each of the Borrowers have conducted a
               --------------------
     comprehensive review and assessment of each of the Borrower's computer
     applications and made inquiry of each of the Borrower's key suppliers,
     vendors, customers, and Investors with respect to the "Year 2000 Problem"
     and, based on that review and inquiry, the Borrowers do not believe the
     Year 2000 Problem will result in a material adverse change in the
     Borrowers' business condition (financial or otherwise), operations,
     properties or prospects, or ability to repay the credit.

          5.19 Assumed Names. The Borrowers do not originate Mortgage Loans or
               -------------
otherwise conduct business under any names other than its legal name and the
assumed name(s) set forth on Exhibit O attached hereto and made a part hereof.
The Borrowers have made all filings and taken all other action as may be
required under the laws of any jurisdiction in which it originates Mortgage
Loans or otherwise conducts business under any assumed name. The Borrowers' use
of assumed name(s) set forth herein does not conflict with any other Person's
legal rights to any such name(s), nor otherwise give rise to any liability by
the Borrowers to any other Person.

6.   AFFIRMATIVE COVENANTS.

          The Borrowers hereby covenant and agree that, so long as the
     Commitment is outstanding or there remain any Obligations to be paid or

          under a Multiemployer Plan shall have made a complete or partial
          withdrawal from

     hereby expressly waived by the Borrowers.

           8.2(b) Upon the occurrence of any Event of Default, other than those
     described in Sections 0 and 0, the Lender may, by Notice to the Borrowers,
     terminate the Commitment and/or declare all Obligations to be immediately

     Lender to make any Advances shall thereupon terminate.

                                      75
<PAGE>

           8.2(c) Upon the occurrence of any Event of Default, the Lender may
also do any of the following:

                 (1) Foreclose upon or otherwise enforce its security interest
           in and Lien on the Collateral to secure all payments and performance
           of the Obligations in any manner permitted by law or provided for
           hereunder.

                 (2) Notify all obligors in respect of Collateral that the
           Collateral has been assigned to the Lender and that all payments
           thereon are to be made directly to the Lender or such other party as
           may be designated by the Lender; settle, compromise, or release, in
           whole or in part, any amounts owing on the Collateral, any such
           obligor or any Investor or any portion of the Collateral, on terms
           acceptable to the Lender; enforce payment and prosecute any action or
           proceeding with respect to any and all Collateral; and where any such
           Collateral is in default, foreclose on and enforce security interests
           in such Collateral by any available judicial procedure or without
           judicial process and sell property acquired as a result of any such
           foreclosure.

                 (3) Act, or contract with a third party to act, as servicer or
           subservicer of each item of Collateral requiring servicing and
           perform all obligations required in connection with Servicing
           Contracts and Purchase Commitments related to the Collateral, such

                 (4) Require the Borrowers to assemble the Collateral and/or
           books and records relating thereto and make such available to the

           records relating thereto are located and take possession thereof with
           or without judicial process; and obtain access to the

                                      76
<PAGE>

     Borrowers' data processing equipment, computer hardware and software
     relating to the Collateral and to use all of the foregoing and the
     information contained therein in any manner the Lender deems necessary for
     the purpose of effectuating its rights under this Agreement and any other
     Loan Document.

          (6) Prior to the disposition of the Collateral, prepare it for
     disposition in any manner and to the extent the Lender deems appropriate.

          (7) Exercise all rights and remedies of a secured creditor under the
     Uniform Commercial Code of Minnesota or other applicable law, including,
     but not limited to, selling or otherwise disposing of the Collateral, or
     any part thereof, at one or more public or private sales, whether or not
     such Collateral is present at the place of sale, for cash or credit or
     future delivery, on such terms and in such manner as the Lender may
     determine, including, without limitation, sale pursuant to any applicable
     Purchase Commitment. If notice is required under such applicable law, the
     Lender will give the Borrowers not less than 10 days' notice of any such
     public sale or of the date after which any private sale may be held. The
     Borrowers agree that 10 days' notice shall be reasonable notice. The Lender
     may, without notice or publication, adjourn any public or private sale or
     cause the same to be adjourned from time to time by announcement at the
     time and place fixed for the sale, and such sale may be made at any time or
     place to which the same may be so adjourned. In case of any sale of all or
     any part of the Collateral on credit or for future delivery, the Collateral
     so sold may be retained by the Lender until the selling price is paid by
     the purchaser thereof, but the Lender shall not incur any liability in case
     of the failure of such purchaser to take up and pay for the Collateral so
     sold and, in case of any such failure, such Collateral may again be sold
     upon like notice. The

                                      77
<PAGE>

            Lender may, however, instead of exercising the power of sale herein
            conferred upon it, proceed by a suit or suits at law or in equity to
            collect all amounts due upon the Collateral or to foreclose the
            pledge of and sell the Collateral or any portion thereof under a
            judgment or decree of a court or courts of competent jurisdiction,
            or both.

                 (8) Proceed against the Borrowers on the Note or against the
            Guarantor under the Guaranty or both.

            8.2(d) The Lender shall incur no liability as a result of the sale
     or other disposition of the Collateral, or any part thereof, at any public
     or private sale or disposition. The Borrowers hereby waive (to the extent
     permitted by law) any claims they may have against the Lender arising by
     reason of the fact that the price at which the Collateral may have been
     sold at such private sale was less than the price which might have been
     obtained at a public sale or was less than the aggregate amount of the
     outstanding Advances and the unpaid interest accrued thereon, even if the
     Lender accepts the first offer received and does not offer the Collateral
     to more than one offeree. Any sale of Collateral pursuant to the terms of a
     Purchase Commitment, or any other disposition of Collateral arranged by the
     Borrowers, whether before or after the occurrence of an Event of Default,
     shall be deemed to have been made in a commercially reasonable manner.

            8.2(e) The Borrowers acknowledge that Mortgage Loans and Mortgage-
     backed Securities are collateral of a type which is customarily sold on a
     recognized market. The Borrowers waive any right it may have to prior
     notice of the sale of any Pledged Mortgage or Pledged Security, and agrees
     that the Lender may purchase any Pledged Mortgages or Pledged Securities at
     a private sale of such Collateral.

            8.2(f) The Borrowers specifically waive and release (to the extent
     permitted by law) any equity or right of redemption, all rights of
     redemption, stay or

                                      78
<PAGE>

     appraisal which the Borrowers have or may have under any rule of law or
     statute now existing or hereafter adopted, and any right to require the
     Lender to (1) proceed against any Person, (2) proceed against or exhaust
     any of the Collateral or pursue its rights and remedies as against the
     Collateral in any particular order, or (3) pursue any other remedy in its
     power. The Lender shall not be required to take any steps necessary to
     preserve any rights of the Borrowers against holders of mortgages prior in
     lien to the Lien of any Mortgage included in the Collateral or to preserve
     rights against prior parties.

           8.2(g) The Lender may, but shall not be obligated to, advance any
     sums or do any act or thing necessary to uphold and enforce the Lien and
     priority of, or the security intended to be afforded by, any Mortgage
     included in the Collateral, including, without limitation, payment of
     delinquent taxes or assessments and insurance premiums. All advances,
     charges, costs and expenses, including reasonable attorneys' fees and
     disbursements, incurred or paid by the Lender in exercising any right,
     power or remedy conferred by this Agreement, or in the enforcement hereof,
     together with interest thereon, at the Default Rate, from the time of
     payment until repaid, shall become a part of the principal balance
     outstanding hereunder and under the Note.

           8.2(h) No failure on the part of the Lender to exercise, and no delay
     in exercising, any right, power or remedy provided hereunder, at law or in
     equity shall operate as a waiver thereof; nor shall any single or partial
     exercise by the Lender of any right, power or remedy provided hereunder, at
     law or in equity preclude any other or further exercise thereof or the
     exercise of any other right, power or remedy. Without intending to limit
     the foregoing, all defenses based on the statute of limitations are hereby
     waived by the Borrowers to the extent permitted by law. The remedies herein
     provided are cumulative and are not exclusive of any remedies provided at
     law or in equity.

                                      79
<PAGE>

                 8.2(i) The Lender is hereby granted a license or other right to
           use, without charge, the Borrowers' computer programs, other
           programs, labels, patents, copyrights, rights of use of any name,
           trade secrets, trade names, trademarks, service marks and advertising
           matter, or any property of a similar nature, as it pertains to the
           Collateral, in advertising for sale and selling any Collateral, and
           the Borrowers' rights under all licenses and all other agreements
           related to the foregoing shall inure to the Lender's benefit until
           the Obligations are paid in full.

           8.3 Application of Proceeds. The proceeds of any sale, disposition or
               -----------------------
     other enforcement of the Lender's security interest in all or any part of
     the Collateral shall be applied by the Lender to the Obligations in such
     order as the Lender, in its sole and absolute discretion, will determine.

           If the proceeds of any sale, disposition or other enforcement are
     insufficient to cover the costs and expenses of the sale, and the payment
     in full of all Obligations, the Borrowers will remain liable for any
     deficiency.

           8.4 Lender Appointed Attorney-in-Fact. The Lender is hereby appointed
               ---------------------------------
     the attorney-in-fact of the Borrowers, with

                    (END OF PAGE INTENTIONALLY LEFT BLANK)

                                      80
<PAGE>

     full power of substitution, for the purpose of carrying out the
     provisions hereof and taking any action and executing any instruments
     which the Lender may deem necessary or advisable to accomplish the
     purposes hereof, which appointment as attorney-in-fact is irrevocable
     and coupled with an interest. Without limiting the generality of the
     foregoing, the Lender shall have the right and power to give notices of
     its security interest in the Collateral to any Person, either in the
     name of the Borrowers or in its own name, to endorse all Pledged
     Mortgages or Pledged Securities payable to the order of the Borrowers,
     to change or cause to be changed the book-entry registration or name of
     subscriber or Investor on any Pledged Security, or to receive, endorse
     and collect all checks made payable to the order of the Borrowers
     representing any payment on account of the principal of or interest on,
     or the proceeds of sale of, any of the Pledged Mortgages or Pledged
     Securities and to give full discharge for the same.

           8.5 Right of Set-Off. If the Borrowers shall default in the
               ----------------
     payment of the Note, any interest accrued thereon, or any other sums
     which may become payable hereunder when due, or in the performance of
     any of its other obligations or liabilities under this Agreement, the
     Lender shall have the right, at any time and from time to time, without
     notice, to set-off and to appropriate or apply any and all property or
     indebtedness of any kind at any time held or owing by the Lender to or
     for the credit or the account of the Borrowers against and on account
     of the Obligations of the Borrowers under the Note and this Agreement,
     irrespective of whether or not the Lender shall have made any demand
     hereunder and whether or not said Obligations shall have matured.

10.  REIMBURSEMENT OF EXPENSES; INDEMNITY.

     The Borrowers shall: (a) pay a documentation production fee of Ten Thousand
Dollars ($10,000) in connection with the preparation and negotiation of this
Agreement; (b) pay such additional documentation production fees as the Lender
may require and all out-of-pocket costs and expenses of the Lender, including,
without limitation, reasonable fees, service charges and disbursements of
counsel (including allocated costs of internal counsel), in connection with the
amendment, enforcement and administration of this Agreement, the Note, and other
Loan Documents and the making and repayment of the Advances and the payment of
interest thereon; (c) indemnify, pay, and hold harmless the Lender and any
holder of the Note from and against, any and all present and future stamp,
documentary and other similar taxes with respect to the foregoing matters and
save the Lender and the holder or holders of the Note harmless from and against
any and all liabilities with respect to or resulting from any delay or omission
to pay such taxes; and (d) indemnify, pay and hold harmless the Lender and any
of its officers, directors, employees

                                      82
<PAGE>

or agents and any subsequent holder of the Note (collectively called the
"Indemnitees") from and against any and all liabilities, obligations, losses,
damages, penalties, judgments, suits, costs, expenses and disbursements of any
kind or nature whatsoever (including without limitation, the reasonable fees and
disbursements of counsel of the Indemnitees (including allocated costs of
internal counsel) in connection with any investigative, administrative or
judicial proceeding, whether or not such Indemnitees shall be designated a party
thereto) which may be imposed upon, incurred by or asserted against such
Indemnitees in any manner relating to or arising out of this Agreement, the
Note, or any other Loan Document or any of the transactions contemplated hereby
or thereby (the "Indemnified Liabilities"); provided, however, that the
Borrowers shall have no obligation hereunder to the extent that the Indemnified
Liabilities arise from the gross negligence or willful misconduct of any such
Indemnitees. To the extent that the undertaking to indemnify, pay and hold
harmless as set forth in the preceding sentence may be unenforceable because it
is violative of any law or public policy, the Borrowers shall contribute the
maximum portion which they are permitted to pay and satisfy under applicable
law, to the payment and satisfaction of all Indemnified Liabilities incurred by
the Indemnitees or any of them. The agreement of the Borrowers contained in this
Subsection (d) shall survive the expiration or termination of this Agreement and
the payment in full of the Note. Attorneys' fees and disbursements incurred in
enforcing, or on appeal from, a judgment pursuant hereto shall be recoverable
separately from and in addition to any other amount included in such judgment,
and this clause is intended to be severable from the other provisions of this
Agreement and to survive and not be merged into such judgment.

11.  FINANCIAL INFORMATION.

          All financial statements and reports furnished to the Lender hereunder
     shall be prepared in accordance with GAAP, applied on a basis consistent
     with that applied in preparing the financial statements as at the end of
     and for the last fiscal year ended (except to the extent otherwise required

           12.1 Terms Binding Upon Successors; Survival of Representations.
                ----------------------------------------------------------
     The terms and provisions of this Agreement shall be binding upon and inure
     to the benefit of the parties hereto and their respective successors and
     assigns. All representations, warranties, covenants and agreements herein
     contained on the part of the Borrowers shall survive the making of any
     Advance and the execution of the Note, and shall be effective so long as
     the Commitment is outstanding or there remain any Obligations to be paid or
     performed.

           12.2 Assignment. This Agreement cannot be assigned by the Borrowers.
                ----------
     This Agreement and the Note, along with the Lender's security interest in
     any or all of the Collateral, may, at any time, be transferred or assigned,
     in whole or in part, by the Lender, and any assignee thereof may enforce
     this Agreement, the Note and its security interest in the Collateral so
     assigned.

           12.3 Amendments. Except as otherwise provided in this Agreement,
                ----------

     the parties hereto.

           12.4 Governing Law. This Agreement and the other Loan Documents
                -------------
     shall be governed by the laws of the State of Minnesota, without reference

                --------------

     "Participant"), all or part of the Obligations. Without limitation of the
     exclusive right of the Lender to collect and enforce such Obligations, the
     Borrowers agree that each disposition will give rise to a debtor-creditor
     relationship of the Borrowers to the Participant, and the Borrowers
     authorize each Participant, upon the occurrence of an Event of Default, to
     proceed directly by right of setoff, banker's lien, or otherwise, against
     any assets of the Borrowers which may be in the hands of such Participant.
     The Borrowers authorize

     obligating the Lender to control the Borrowers or to conduct the Borrowers'
     operations, as creating any fiduciary obligation on the part of the Lender
     to the Borrowers, or as creating any joint venture, agency, or other
     relationship between the parties hereto other than as explicitly and

           12.7 Severability. If any provision of this Agreement shall be
                ------------
     declared to be illegal or unenforceable in any respect, such illegal or
     unenforceable provision shall be and become absolutely null and void and of
     no force and effect as though such provision were not in fact set forth
     herein, but all other covenants,

<PAGE>

     terms, conditions and provisions hereof shall nevertheless continue to be
     valid and enforceable.

     Borrowers' general mortgage business methods, policies, and procedures,
     auditing loan files and reviewing financial and operational aspects of the
     Borrowers' business.

                -----------------------

     States District Court for the District of Minnesota at the option of the
     Lender; and the Borrowers hereby waive any objection to the jurisdiction or
     venue of any such court with respect to, or the convenience of any court as
     a forum for, any such suit, action or proceeding. Nothing herein shall
     affect the right of the Lender to accomplish service of process in any
     other manner permitted by law or to commence legal proceedings or otherwise
     proceed against the Borrowers in any other jurisdiction or court.

           12.10 Counterparts. This Agreement may be executed in any number
                 ------------

           12.11 Entire Agreement. This Agreement, the Note and the other
                 ----------------
     Loan Documents represent the final agreement among the parties hereto and
     thereto with respect to the subject matter hereof and thereof, and may not
     be contradicted by evidence of prior or contemporaneous oral

     agreements among such parties. There are no oral agreements among the

2.       As illustrated in the attached calculations supporting this Officer's
         Certificate, the Borrowers met the covenants set forth in Sections 0,

         detailed explanation is attached setting forth the nature and period of
         the existence of the Default and the action the Borrowers have taken,
         are taking, and propose to take with respect thereto.

3.       No Servicing Contracts have been sold or pledged by the Borrowers
         except as permitted under the terms of the Agreement.

         propose to take with respect thereto are specified in the statement
         attached hereto.

8.       I have reviewed the terms of the Agreement and have made, or caused to
         be made under my supervision, a review in reasonable detail of the
         transactions and conditions of the Borrowers (and, if applicable, their
         Subsidiaries) and such review has not disclosed the existence, and I
         have no knowledge of the existence, of any Default or Event of Default,
         or if any Default or Event of Default existed or exists, a detailed
         explanation is attached specifying the nature and period of the

failure to proceed against or join each Co-Borrower shall not affect the joint
and several liability of each Co-Borrower.

         This Note shall be construed and enforced in accordance with the laws
of the State of Minnesota, without reference to its principles of conflicts of
law.

         IN WITNESS WHEREOF, the Borrowers have executed this Note as of the day
and year first above written.

EXHIBIT B

                                       GUARANTY
                                       --------

         THIS GUARANTY, made and entered into as of this 29th day of December
1999, by NFI HOLDING CORPORATION (the "Guarantor"), to RESIDENTIAL FUNDING
CORPORATION, a Delaware corporation (the "Lender"), having its principal office
at 8400 Normandale Lake Blvd., Suite 600, Minneapolis, Minnesota 55437.

                                       RECITALS
                                       --------

         A.       NOVASTAR FINANCIAL, INC., a Maryland corporation ("NFI"),
                  NOVASTAR MORTGAGE, INC., a Virginia corporation ("NMI"), and
                  NOVASTAR CAPITAL, INC., a Delaware corporation ("NCI") (NFI,
                  NMI and NCI are hereinafter collectively referred to as the
                  "Borrowers") and the Lender have agreed that the Lender will
                  extend a warehouse line of credit to the Borrowers in the
                  principal amount of Fifty Million Dollars ($50,000,000) (the
                  "Loan") to finance the making and purchasing of Mortgage
                  Loans.

         B.       The Loan is evidenced by a Promissory Note, dated of even date
                  herewith from the Borrowers to the Lender, as the same may be
                  amended, supplemented or otherwise modified from time to time,
                  including any other instruments executed and delivered in
                  renewal, extension, rearrangement or otherwise in replacement
                  of such Promissory Note (the "Note") and by a Warehousing
                  Credit and Security Agreement of even date herewith, as the
                  same may be amended, supplemented or otherwise modified from
                  time to time, including any other instruments executed and
                  delivered in renewal, extension, rearrangement or otherwise in
                  replacement of such agreement (the "Agreement").

         C.       The Guarantor is the Parent of NMI and NCI, an Affiliate of
                  NFI and will derive benefit from the Loan.

         D.       As a condition to making the Loan, the Lender has required
                  that the Guarantor execute and deliver this Guaranty. In order
                  to induce the Lender to make Advances under the Agreement, and
                  to accept the Notes and the Agreement, the Guarantor has
                  agreed to give this Guaranty.

         E.       The Lender has refused to make Advances under the Agreement
                  unless this Guaranty is executed by the Guarantor and
                  delivered to Lender.

                                   AGREEMENT
                                   ---------

         NOW, THEREFORE, in consideration of the recitals and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Guarantor hereby covenants and agrees with the Lender as
follows:

         1.    Unless otherwise defined herein, all capitalized terms used
herein shall have the meanings ascribed to such terms in the Agreement.

         2.    The Guarantor hereby irrevocably, unconditionally and absolutely
guarantees to the Lender the due and prompt payment, and not just the
collectibility, of the principal of, and interest, fees and late charges and all
other indebtedness, if any, on the Notes when due, whether at maturity, by
acceleration or otherwise all at the times and places and at the rates described
in, and otherwise according to the terms of the Notes and the Agreement, whether
now existing or hereafter created or arising.

         3.    The Guarantor further hereby irrevocably, unconditionally and
absolutely guarantees to the Lender the due and prompt performance by the
Borrowers of all duties, agreements and obligations of the Borrowers contained
in the Note and the Agreement, and the due and prompt payment of all costs and
expenses incurred, including, without limitation, attorneys' fees, court costs
and all other litigation expenses (including but not limited to expert witness
fees, exhibit preparation, and courier, postage, communication and document
copying expenses), in enforcing the payment
<PAGE>

and performance of the Notes and the Agreement and this Guaranty (the payment
and performance of the items set forth in Paragraphs 2 and 3 of this Guaranty
are collectively referred to as the "Guaranteed Debt").

         4. In the event the Borrowers shall at any time fail to pay the Lender
any principal of or interest on or other sums constituting any Guaranteed Debt
when due, whether by acceleration or otherwise, the Guarantor promises to pay
such amount to the Lender forthwith, together with all collection costs and
expenses, including, without limitation, attorneys' fees, court costs and all
other litigation expenses (including but not limited to expert witness fees,
exhibit preparation, and courier, postage, communication and document copying
expenses). Any sum required to be paid by the Guarantor to the Lender pursuant
to this Guaranty shall bear interest from the date such sum becomes due until
paid at a per annum rate equal to the Default Rate.

         5. The Guarantor hereby authorizes the Lender, following the occurrence
of an Event of Default, without notice or demand, to apply any property,
balances, credits, accounts or moneys of the Guarantor then in the possession of
Lender, or standing to the credit of the Guarantor, to the payment of such
Guaranteed Debt.

         6. The Guarantor does hereby (a) agree to any modifications of any
terms or conditions of any Guaranteed Debt and/or to any extensions or renewals
of time of payment or performance by the Borrowers; (b) that it shall not be
necessary for the Lender to resort to legal remedies against the Borrowers
before proceeding hereunder, nor to take any action against any other Person
obligated (an "Obligor") for payment or performance of the Guaranteed Debt or
against any collateral for the Guaranteed Debt before proceeding against the
Guarantor; (c) agree that no release of the Borrowers or any other guarantor or
Obligor, and no release, exchange or nonperfection of any collateral for the
Guaranteed Debt, whether by operation of law or by any act or failure to act by
the Lender, with or without notice to the Guarantor, shall release the
Guarantor; (d) waive presentment, demand, notice of demand, dishonor, notice of
dishonor, protest, and notice of protest and any other notice with respect to
any Guaranteed Debt and this Guaranty, and promptness in commencing suit against
any party thereto or liable thereon and/or in giving any notice to or making any
claim or demand hereunder upon the Guarantor; (e) waive any defense arising by
reason of any disability or other defense of the Borrowers for payment of the
Guaranteed Debt or any part thereof or by reason of the cessation from any cause
whatsoever of the liability of the Borrowers therefor other than full payment of
the Guaranteed Debt; or (f) waive, to the extent permitted by law, all benefit
of valuation, appraisement, and exemptions under the laws of the State of
Minnesota or any other state or territory of the United States.

         7. The obligations of the Guarantor hereunder shall be primary,
absolute and unconditional, and shall remain in full force and effect without
regard to, and shall not be impaired or affected by: (a) the genuineness,
validity, regularity or enforceability of, or any amendment or change in the
Agreement or the Notes, or any change in or extension of the manner, place or
terms of payment of, all or any portion of the Guaranteed Debt; (b) the taking
or failure to take any action to enforce the Agreement or the Notes, or the
exercise or failure to exercise any remedy, power or privilege contained therein
or available at law or otherwise, or the waiver by the Lender of any provisions
of the Agreement or the Notes; (c) any impairment, modification, change, release
or limitation in any manner of the liability of the Borrowers or their estate in
bankruptcy, or of any remedy for the enforcement of the Borrowers' liability,
resulting from the operation of any present or future provision of the
bankruptcy laws or any other statute or regulation, or the dissolution,
bankruptcy, insolvency, or reorganization of the Borrowers; (d) the merger or
consolidation of the Borrowers, or any sale or transfer by the Borrowers of all
or part of its assets or property; (e) any claim the Guarantor may have against
any other Obligor, including any claim of contribution; (f) the release, in
whole or in part, of any other guarantor (if more than one), the Borrowers or
any other Obligor; (g) any settlement or compromise with any Obligor with
respect to any Guaranteed Debt and/or the subordination of the payment of the
Guaranteed Debt or any part thereof to the payment of any other debts or claims
which may at any time be due and owing to the Lender and/or any other Person; or
(h) any other action or circumstance which (with or without notice to or
knowledge of the Guarantor) may or might in any manner or to any extent vary the
risks of the Guarantor hereunder or otherwise constitute a legal or equitable
discharge or defense, it being understood and agreed by the Guarantor that the
obligations under this Guaranty shall not be discharged except by the full
payment and performance of the Guaranteed Debt.

         8. The Lender shall have the right to determine how, when and what
application of payments and credits, if any, whether derived from the Borrowers
or from any other source, shall be made on the Guaranteed Debt and any other
indebtedness owed by the Borrowers and/or any other Obligor to the Lender. The
Lender shall be under no obligation to marshal any assets in favor of the
Guarantor or in payment of all or any part of the Guaranteed Debt.
<PAGE>

         9. The obligations of the Guarantor hereunder shall continue to be
effective, or be automatically reinstated, as the case may be, if at any time
the performance or the payment, as the case may be, in whole or in part, of any
of the Guaranteed Debt is rescinded or must otherwise be restored or returned by
the Lender (as a preference, fraudulent conveyance or otherwise) upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrowers, the Guarantor or any other person or upon or as a result of the
appointment of a custodian, receiver, trustee or other officer with similar
powers with respect to the Borrowers, the Guarantor or any other person, or any
substantial part of its property, or otherwise, all as though such payments had
not been made. If an Event of Default shall at any time have occurred and be
continuing or shall exist and declaration of default or acceleration under or
with respect to this Guaranty or any Guaranteed Debt shall at such time be
prevented by reason of the pendency against the Guarantor or the Borrowers or
any other Person of a case or proceeding under a bankruptcy or insolvency law,
the Guarantor agrees that, for purposes of this Guaranty and its obligations
hereunder, this Guaranty and such obligations shall be deemed to have been
declared in default or accelerated with the same effect as if this Guaranty and
such obligations had been declared in default and accelerated in accordance with
their respective terms and the Guarantor shall forthwith perform or pay, as the
case may be, as required hereunder in accordance with the terms hereunder
without further notice or demand.

         10. The Guarantor hereby irrevocably waives any claim or other rights
that the Guarantor may now or hereafter acquire against the Borrowers that
arises from the existence, payment, performance or enforcement of the
Guarantor's obligations hereunder, including any right of subrogation,
reimbursement, exoneration, contribution or indemnification, any right to
participate in any claim or remedy of the Lender against the Borrowers or any
collateral that the Lender now has or hereafter acquires, whether or not such
claim, remedy or right arises in equity or under contract, statute or common
law, including the right to take or receive from the Borrowers directly or
indirectly, in cash or other property or by set-off or in any manner, payment or
security on account of such claim or other rights. If any amount shall be paid
to the Guarantor in violation of the preceding sentence and the Guaranteed Debt
shall not have been paid and performed in full, such amount shall be deemed to
have been paid to the Guarantor for the benefit of, and held in trust for, the
Lender and shall forthwith be paid to the Lender to be credited and applied to
the Guaranteed Debt, whether matured or unmatured. Notwithstanding the blanket
waiver of subrogation rights as set forth above, the Guarantor hereby
specifically acknowledges that any subrogation rights which the Guarantor may
have against the Borrowers or any collateral that the Lender now has or
hereafter acquires may be destroyed by a nonjudicial foreclosure of the
collateral. Without limiting the foregoing, the Guarantor waives all rights and
defenses arising out of an election of remedies by the Lender, even though that
election of remedies, such as a nonjudicial foreclosure with respect to security
for any Guaranteed Debt, has destroyed the Guarantor's rights of subrogation and
reimbursement against the Borrowers by the operation of Section 580d of the
California Code of Civil Procedure or otherwise. The Guarantor acknowledges that
the Guarantor will receive direct and indirect benefits from the arrangements
contemplated by the Agreement and the Notes and that the waivers set forth in
this Section are knowingly made in contemplation of such benefits.

         11. No postponement or delay on the part of the Lender in the
enforcement of any right hereunder shall constitute a waiver of such right and
all rights of the Lender hereunder shall be cumulative and not alternative and
shall be in addition to any other rights granted to the Lender in any other
agreement or by law.

         12. If any provision hereof shall be or shall be declared to be illegal
or unenforceable in any respect, such illegal or unenforceable provision shall
be and become absolutely null and void and of no force and effect as though such
provision were not in fact set forth herein, but all other covenants, terms,
conditions and provisions hereof shall nevertheless continue to be valid and
enforceable and this Guaranty shall be so construed.

         13. This Guaranty shall be governed in all respects by the laws of the
State of Minnesota, other than its principles of conflicts of law, and shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective heirs, executors, administrators, personal representatives,
successors and assigns.

         14. The Guarantor hereby agrees that any action or proceeding under
this Guaranty may be commenced against the Guarantor in any court of competent
jurisdiction within the State of Minnesota, by service of process upon the
Guarantor by first class registered or certified mail, return receipt requested,
addressed to the Guarantor at the Guarantor's address last known to the Lender.
The Guarantor agrees that any such suit, action or proceeding arising out of or
relating to this Guaranty may be instituted in the District Court of Hennepin
County, Minnesota or in the United States District Court for the District of
Minnesota, at the option of the Lender; and the Guarantor hereby waives any
objection to the jurisdiction or venue of any such court with respect to, or the
convenience of any such court as a forum for, any such suit, action or
proceeding. Nothing herein shall affect the right of the Lender to accomplish
service of
<PAGE>

process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against the Guarantor in any other jurisdiction or court.

         15.   The Guarantor hereby represents and warrants to the Lender as
follows:

         (a)   Organization and Qualification. The Guarantor is a corporation
               duly organized, validly existing and in good standing under the
               laws of its jurisdiction of incorporation. The Guarantor is duly
               qualified to do business as a foreign corporation and in good
               standing in all jurisdictions in which the ownership of its
               properties or the nature of its activities, or both, makes such
               qualification necessary.

         (b)   Authority and Authorization. The Guarantor has full corporate
               power and authority to execute, deliver and carry out the
               provisions of this Guaranty and to perform its obligations
               hereunder, and all such action has been duly and validly
               authorized by all necessary corporate proceedings on its part.

         (c)   Financial Statements. All financial statements and data which
               have heretofore been given to the Lender with respect to the
               Guarantor fairly and accurately represent the financial condition
               of the Guarantor as of the date hereof, and, since the date
               thereof, there has been no material adverse change in the
               financial condition of the Guarantor. The Guarantor shall
               promptly deliver to the Lender, or to the Borrowers in time for
               the Borrowers to deliver the same to the Lender, all financial
               statements and tax returns of the Guarantor required by the
               Agreement.

         (d)   Address. The address of the Guarantor as specified below is true
               and correct and until the Lender shall have actually received a
               written notice specifying a change of address and specifically
               requesting that notices be issued to such changed address, the
               Lender may rely on the address stated as being accurate.

         (e)   No Default. The Guarantor is not in default with respect to any
               order, writ, injunction, decree or demand of any court or other
               governmental authority, in the payment of any material debt for
               borrowed money or under any material agreement evidencing or
               securing any such debt.

         (f)   Solvent. The Guarantor is now solvent, and no bankruptcy or
               insolvency proceedings are pending or to the best of the
               Guarantor's knowledge contemplated by or against the Guarantor.

         (g)   Relationship to the Borrowers. The value of the consideration
               received and to be received by the Guarantor is reasonably worth
               at least as much as the liability and obligation of the Guarantor
               incurred or arising under this Guaranty. The Guarantor has had
               full and complete access to the Agreement and the Notes and all
               other loan documents relating to the Obligations and the
               Guaranteed Debt, has reviewed them and is fully aware of the
               meaning and effect of their contents. The Guarantor is fully
               informed of all circumstances which bear upon the risks of
               executing this Guaranty and which a diligent inquiry would
               reveal. The Guarantor has adequate means to obtain from the
               Borrowers on a continuing basis information concerning the
               Borrowers' financial condition, and is not depending on the
               Lender to provide such information, now or in the future. The
               Guarantor agrees that the Lender shall not have any obligation to
               advise or notify the Guarantor or to provide the Guarantor with
               any data or information. The execution and delivery of this
               Guaranty is not given in consideration of (and the Lender has not
               in any way implied that the execution of this Guaranty is given
               in consideration of) the Lender's making, extending or modifying
               any loan to the Guarantor or to any other financial accommodation
               to or for the Guarantor.

         (h)   Litigation. There is not now pending against or affecting the
               Guarantor, nor to the knowledge of the Guarantor is there
               threatened, any action, suit or proceeding at law or in equity or
               by or before any administrative agency that, if adversely
               determined, would materially impair or affect the financial
               condition of the Guarantor.

         (i)   Taxes. The Guarantor has filed all federal, state, provincial,
               county, municipal and other income tax returns required to have
               been filed by the Guarantor and has paid all taxes that have
               become due
<PAGE>

               pursuant to such returns or pursuant to any assessments received
               by the Guarantor, and the Guarantor does not know of any basis
               for any material additional assessment against it in respect of
               such taxes.

         16.   Neither the death nor the release of any person or party to this
Guaranty or any other guaranties of the Agreement and the Notes shall affect or
release the liability of the Guarantor. The obligations of the Guarantor
hereunder shall be in addition to any obligations of the Guarantor under any
other guaranties of the Guaranteed Debt and/or any obligations of the Borrowers
or any other Persons heretofore given or hereafter to be given to the Lender,
and this Guaranty shall not affect or invalidate any such other guaranties. The
liability of the Guarantor to the Lender shall at all times be deemed to be the
aggregate liability of the Guarantor under the terms of this Guaranty and of any
other guaranties heretofore or hereafter given by the Guarantor to the Lender.

         17.   No amendment or waiver of any provision of this Guaranty nor
consent to any departure by the Guarantor therefrom shall in any event be
effective unless the same shall be in writing and signed by the Lender, and then
such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. No notice to or demand on the Guarantor
shall in any case entitle it to any other or further notice or demand in similar
or other circumstances.

         18.   All notices that may be required or otherwise provided for or
