                  determined by the Agent at such time based on such other

                  if necessary, to the nearest 1/16 of 1%).

                           "Jumbo Mortgage Loan" means a Mortgage Loan which
                  would in all respects be a Conforming Loan but for the fact

                  Mortgage Note is greater than $240,000 (but does not exceed
                  $750,000).

                  Investor to which such Mortgage Loan is to be sold by a
                  Borrower under a Take-Out Commitment, provided that such
                  underwriting guidelines or other applicable standards comply
                  with industry standards in the sole judgment of Agent.

                  (e) Section 2.01(b) of the Credit Agreement is hereby amended
         in its entirety to read as follows:

                      (b) Discretionary Swingline Commitment. Upon the terms and
                  subject to the conditions of this Agreement, until the
                  Drawdown Termination Date, U.S. Bank, in its sole discretion,
                  may lend to the Borrowers loans (each such loan, a "Swingline
                  Loan") at such times and in such amounts as the Company shall
                  request, up to an aggregate principal amount at any time
                  outstanding equal to the amount by which U.S. Bank's
                  Commitment Amount exceeds the principal amount outstanding
                  under U.S. Bank's Note; provided, that U.S. Bank will not make
                  a Swingline Loan if (i) after giving effect thereto, any of
                  the limitations set forth in Section 2.01(a) would be exceeded
                  or (ii) U.S. Bank has received written notice from the Company
                  or any Lender that one or more of the conditions precedent set
                  forth in Article III for the making of a Loan have not been
                  satisfied.

                  (f) Section 2.03(a) of the Credit Agreement is hereby amended
         in its entirety to read as follows:

                      (a) Notice and Manner of Obtaining Loans. The Company
                  shall give Agent telephonic notice of each request for Loans
                  not later than 1:00 p.m. (Minneapolis, Minnesota time) on the
                  requested Borrowing Date and of each request for Swingline
                  Loans not later than 3:00 p.m. (Minneapolis, Minnesota time)
                  on the requested Borrowing Date. Each request for Loans or
                  Swingline Loans shall specify the aggregate amount of Loans or
                  Swingline Loans requested, whether each such Loan or Swingline
                  Loan is being made to permit a Co-Borrower to originate or
                  acquire one or more Mortgage Loans (and, if so, specifying the
                  Co-Borrower), and whether such Loans to be made by each Lender
                  are to be funded as Reference Rate Advances, Eurodollar Rate
                  Advances or Balance Funded Rate Advances; provided, that any
                  portion of a Loan not so designated shall be funded as a
                  Eurodollar Rate Advance. Agent shall notify each Lender via
                  facsimile and telephone by not later than 2:00 P.M.
                  (Minneapolis, Minnesota time) on the date it receives such
                  request of each request for Loans received from the Company,
                  of such Lenders's Percentage Share of the Loans requested and
                  whether such Lender's Loans are to funded as Reference Rate
                  Advances, Eurodollar Rate Advances or Balance Funded Rate
                  Advances. The Company shall, not later than the following
                  Business Day, confirm any such request by delivering to Agent
                  a Confirmation. Each request for Loans shall be irrevocable
                  and binding on the Company and any applicable Co-Borrower. If
                  all conditions precedent to such Loan have been met, each
                  Lender shall deposit into the Collateral Account in
                  immediately available dollars by not later than 4:00 P.M.
                  (Minneapolis, Minnesota time) on the Borrowing Date the amount
                  of such Lender's Loan and upon receipt of such funds, Agent
                  shall promptly make such funds available to the Company and
                  any applicable Co-Borrower by depositing

                                       -3-



                  such funds in the Good Funds Wire Clearing Account or the
                  Operating Account, as requested by the Company. On the
                  Borrowing Date of requested Swingline Loans, U.S. Bank may
                  deposit into the Collateral Account in Immediately Available
                  Funds by not later than 4:00 p.m. (Minneapolis, Minnesota
                  time) on the requested Borrowing Date the amount of the
                  requested Swingline Loans. Unless Agent shall have received
                  notice from a Lender prior to 3:00 P.M. (Minneapolis,
                  Minnesota time) on any Borrowing Date that such Lender will
                  not make available to Agent such Lender's Loan, Agent may in
                  its discretion assume that such Lender has made such Loan
                  available to Agent in accordance with this section and Agent
                  may if it chooses, in reliance upon such assumption make such
                  Loan available to the Company and any applicable Co-Borrower.
                  If and to the extent such Lender shall not so make its Loan
                  available to Agent, such Lender shall, on demand, pay to Agent
                  the amount of such Loan together with interest thereon, for
                  each day from the date such amount is made available to the
                  Company and any applicable Co-Borrower until the date such
                  amount is paid or repaid to Agent at the Federal Funds Rate.
                  If such Lender does not pay such amount promptly upon Agent's
                  demand therefor, Agent shall notify the Company and the
                  Company and each applicable Co-Borrower shall immediately
                  repay such amount to Agent together with accrued interest
                  thereon at the applicable rate or rates provided in Section
                  2.04. Agent shall use its best efforts to demand any such
                  amount from both such Lender and the Company, provided, that
                  any failure by Agent to make any such demand on both such
                  Lender and the Company shall not in any manner affect such
                  Lender's, the Company's or any applicable Co-Borrower's
                  obligation to pay or repay such amount, with interest, as set
                  forth herein. The failure of any Lender to make any Loan to be
                  made by it hereunder shall not relieve any other Lender of its
                  obligation hereunder, if any, to make its Loan, but no Lender
                  shall be responsible for the failure of any other Lender to
                  make any Loan to be made by such other Lender. Each request
                  for Loans or Swingline Loans shall be deemed to be a
                  representation by the Company that (i) no Event of Default or
                  Default has occurred or will exist upon the making of the
                  requested Loans or Swingline Loans and (ii) the
                  representations and warranties contained in Section 4 hereof
                  and in Section 5 of the Security Agreement are true and
                  correct with the same force and effect as if made on and as of
                  the date of such request.

                  (g)     Section 2.03(b)(iii) of the Credit Agreement is hereby
         amended in its entirety to read as follows:

                          (iii) Lenders' Obligation to Fund Refinancings of
                  Swingline Loans. Upon the giving of notice by U.S. Bank under
                  Section 2.03(b)(i) or 2.03(b)(ii), each Lender (including U.S.
                  Bank) shall make a Loan in an amount equal to its Percentage
                  Share of the aggregate principal amount of Swingline Loans to
                  be refinanced, and provide proceeds of such Loans, in
                  immediately available funds, by not later than 3:00 P.M.
                  (Minneapolis time) on the date such notice was received;
                  provided, however, that a Lender shall not be obligated to
                  make any such Loan unless (A) U.S. Bank believed in good faith
                  that all conditions to making the subject Swingline Loan were
                  satisfied at the time such Swingline Loan was made, or (B) if
                  the conditions to such Swingline Loan were not

                                       -4-



                  satisfied, such Lender had actual knowledge, by receipt of the
                  statements furnished to it pursuant to Section 4.01 or
                  otherwise, that any such condition had not been satisfied and
                  failed to notify U.S. Bank in a writing received by U.S. Bank
                  prior to the time it made such Swingline Loan that U.S. Bank
                  was not authorized to make a Swingline Loan until such
                  condition had been satisfied, or U.S. Bank was obligated to
                  give notice of the occurrence of an Event of Default or a
                  Default to Lenders pursuant to Section 8.08 and failed to do
                  so, or (C) any conditions to the making of such Swingline Loan
                  that were not satisfied had been waived in writing by Majority
                  Lenders prior to or at the time such Swingline Loan was made.
                  The proceeds of Loans made pursuant to the preceding sentence
                  shall be paid to U.S. Bank (and not to any Borrower) and
                  applied to the payment of principal of the outstanding
                  Swingline Loans, and the Company authorizes Agent to charge
                  the Collateral Account or any other account (other than escrow
                  or custodial accounts) maintained by the Company with Agent
                  (up to the amount available therein) in order to immediately
                  pay U.S. Bank the principal amount of such Swingline Loans to
                  the extent Loans made by the Lenders are not sufficient to
                  repay in full the principal of the outstanding Swingline Loans
                  requested or required to be refinanced. Upon the making of a
                  Loan by a Lender pursuant to this Section 2.03(b)(iii), the
                  amount so funded shall become due under such Lender's Note and
                  the outstanding principal amount of the Swingline Loans shall
                  be correspondingly reduced. If any portion of any Loan made by
                  Lenders pursuant to this Section 2.03(b)(iii) should be
                  recovered by or on behalf of any Borrower from U.S. Bank in
                  bankruptcy or otherwise, the loss of the amount so recovered
                  shall be ratably shared among all Lenders in the manner
                  contemplated by Section 9.11. Each Lender's obligation to make
                  Loans referred to in this Section 2.03(b) shall, subject to
                  the proviso to the first sentence of this Section
                  2.03(b)(iii), be absolute and unconditional and shall not be
                  affected by any circumstance, including, without limitation,
                  (1) any setoff, counterclaim, recoupment, defense or other
                  right which such Lender may have against U.S. Bank, any
                  Borrower or anyone else for any reason whatsoever; (2) the
                  occurrence or continuance of a Default or an Event of Default;
                  (3) any adverse change in the condition (financial or
                  otherwise) of the Company or any Co-Borrower; (4) any breach
                  of this Agreement by any Borrower, the Agent or any Lender; or
                  (5) any other circumstance, happening or event whatsoever,
                  whether or not similar to any of the foregoing; provided, that
                  in no event shall a Lender be obligated to make a Loan if,
                  after giving effect thereto, the outstanding principal balance
                  of such Lender's Note would exceed its Commitment Amount.

                  (h)     Sections 2.04(a) and (b) of the Credit Agreement are
         hereby amended in their entirety to read as follows:

                          (a) Interest Rates; Balances Deficiency Fees. The
                  Borrowers will pay the Agent monthly in arrears, within two
                  Business Days after the Company's receipt of Agent's statement
                  therefor, interest on the unpaid principal balance of each
                  Advance of each Lender from time to time outstanding as
                  follows:

          or at such other addresses or to such individual's or department's
          attention as the Company or the Agent may have furnished the other
          party in writing. Any communication so addressed and mailed shall be
          deemed to be given when so mailed, except that requests for loans,
          Confirmations and other communications related thereto shall not be
          effective until actually received by Agent or the Company, as the case
          may be; and any notice so sent by rapid transmission shall be deemed
          to be given when receipt of such transmission is acknowledged, and any

                                      -11-



          Agent, as the case may be. Each Co-Borrower hereby authorizes the
          Agent and the Lenders to send all notices under this Agreement and the
          Loan Documents to the Company, on behalf of such Co-Borrower, and the
          Company undertakes to provide such notices to the applicable
          Co-Borrower(s).

               Section 10.02 Amendments, etc. No amendment or waiver of any
          provision of this Agreement, the Security Instruments, the Notes, or
          any other Loan Document, nor consent to any departure by any Borrower
          or any Restricted Subsidiary from the terms thereof, shall in any
          event be effective unless (a) the same shall be in writing and signed
          by (i) if such party is a Borrower, by the Company, (ii) if such party
          is Agent, by Agent and (iii) if such party is a Lender, by such Lender
          or by Agent on behalf of Lenders with the written consent of Majority
          Lenders (or without further consent than that already provided herein
          in the circumstances provided in Section 10.16) and (b) in the case of
          an amendment other than the first and second amendment and other than
          annual renewals or temporary extensions related to annual renewals,
          the Agent, on behalf of each Lender executing such amendment, shall
          have received an amendment fee from the Company in the amount of one
          thousand five hundred dollars ($1,500) for each Lender executing such
          amendment. Notwithstanding the foregoing or anything to the contrary
          herein, Agent shall not, without the prior consent of each individual
          Lender, execute and deliver on behalf of such Lender any waiver or
          amendment which would: (i) waive any of the conditions specified in
          Article III (provided that Agent may in its discretions withdraw any
          request it has made under Section 3.02(g)), (ii) increase the
          Percentage Share of the Commitment of such Lender or subject such
          Lender to any additional obligations, (iii) reduce any fees hereunder,
          or the principal of, or interest on, such Lender's Note, (iv) amend
          the definition herein of "Majority Lenders" or otherwise change the
          aggregate amount of Percentage Shares which is required for Agent,
          Lenders or any of them to take any particular action under the Loan
          Documents, (v) release any Borrower from its obligation to pay such
          Lender's Note, (vi) amend the definitions of "Collateral Value,"
          "Drawdown Termination Date," and "Mortgage Collateral," (vii) release
          any Collateral except in accordance with and pursuant to the Loan
          Documents, or (viii) change the date on which any payments of
          principal, interest or fees are due hereunder.

          (p)  Article X of the Credit Agreement is hereby amended to add the
     following after Section 10.18:

               Section 10.19 Relationship Among Borrowers.

                    (a) JOINT AND SEVERAL LIABILITY. THE COMPANY AGREES THAT IT
               IS LIABLE FOR THE PAYMENT OF ALL OBLIGATIONS OF THE BORROWERS
               UNDER THIS AGREEMENT, AND THAT THE LENDERS AND THE AGENT CAN
               ENFORCE SUCH OBLIGATIONS AGAINST THE COMPANY, IN THE LENDERS' OR
               THE AGENT'S SOLE AND UNLIMITED DISCRETION. EACH CO-BORROWER
               AGREES THAT IT IS

                                      -12-



               LIABLE ONLY FOR THE PAYMENT OF LOANS AND SWINGLINE LOANS MADE TO
               ENABLE IT TO ORIGINATE OR ACQUIRE MORTGAGE LOANS, INTEREST ON
               SUCH LOANS AND SWINGLINE LOANS, AND FEES, COSTS AND EXPENSES
               RELATED TO SUCH LOANS AND SWINGLINE LOANS AND SUCH CO-BORROWER'S
               PERFORMANCE OR NON-PERFORMANCE OF ITS OBLIGATIONS HEREUNDER. THE
               COMPANY AGREES THAT IT IS JOINTLY AND SEVERALLY LIABLE WITH EACH
               CO-BORROWER FOR SUCH CO-BORROWER'S OBLIGATIONS, AS DESCRIBED IN
               THE PRECEDING SENTENCE.

                    (b)  Waivers of Defenses. The obligations of the Borrowers
               hereunder shall not be released, in whole or in part, by any
               action or thing which might, but for this provision of this
               Agreement, be deemed a legal or equitable discharge of a surety
               or guarantor, other than irrevocable payment and performance in
               full of the Obligations (except for contingent indemnity and
               other contingent Obligations not yet due and payable) at a time
               after any obligation of the Lenders hereunder to make Loans shall
               have expired or been terminated. The purpose and intent of this
               Agreement is that the Obligations constitute the direct and
               primary obligations of the Company and, to the extent provided in
               Section 10.19(a), each Co-Borrower, and that the covenants,
               agreements and all obligations of each Borrower hereunder be
               absolute, unconditional and irrevocable. Each Borrower shall be
               and remain liable for any deficiency remaining after foreclosure
               of any mortgage, deed of trust or security agreement securing all
               or any part of the Obligations for which it is liable, whether or
               not the liability of any other Person for such deficiency is
               discharged pursuant to statute, judicial decision or otherwise.

                    (c)  Other Transactions. The Lenders and the Agent are
               expressly authorized to exchange, surrender or release with or
               without consideration any or all collateral and security which
               may at any time be placed with it by any Borrower or by any other
               Person on behalf of the Borrowers, or to forward or deliver any
               or all such collateral and security directly to the Company or
               the applicable Co-Borrower for collection and remittance or for
               credit. No invalidity, irregularity or unenforceability of any
               security for the Obligations or other recourse with respect
               thereto shall affect, impair or be a defense to the Borrowers'
               obligations under this Agreement. The liabilities of each
               Borrower hereunder shall not be affected or impaired by any
               failure, delay, neglect or omission on the part of any Lender or
               the Agent to realize upon any of the Obligations of any other
               Borrower to the Lenders or the Agent, or upon any collateral or
               security for any or all of the Obligations, nor by the taking by
               any Lender or the Agent of (or the failure to take) any guaranty
               or guaranties to secure the Obligations, nor by the taking by any
               Lender or the Agent of (or the failure to take or the failure to
               perfect its security interest in or other lien on) collateral or
               security of any kind. No act or omission of any Lender or

                                      -13-



               the Agent, whether or not such action or failure to act varies or
               increases the risk of, or affects the rights or remedies of a
               Borrower, shall affect or impair the obligations of the Borrowers
               hereunder.

                    (d) Actions Not Required. Each Borrower, to the extent
               permitted by applicable law, hereby waives any and all right to
               cause a marshaling of the assets of any other Borrower or any
               other action by any court or other governmental body with respect
               thereto or to cause any Lender or the Agent to proceed against
               any security for the Obligations or any other recourse which any
               Lender or the Agent may have with respect thereto and further
               waives any and all requirements that any Lender or the Agent
               institute any action or proceeding at law or in equity, or obtain
               any judgment, against any other Borrower or any other Person, or
               with respect to any collateral security for the Obligations, as a
               condition precedent to making demand on or bringing an action or
               obtaining and/or enforcing a judgment against, such Borrower
               under this Agreement.

                    (e) Subrogation. Notwithstanding any payment or payments
               made by any Borrower hereunder or any setoff or application of
               funds of any Borrower by any Lender or the Agent, such Borrower
               shall not be entitled to be subrogated to any of the rights of
               any Lender or the Agent against any other Borrower or any other
               guarantor or any collateral security or guaranty or right of
               offset held by any Lender or the Agent for the payment of the
               Obligations, nor shall such Borrower seek or be entitled to seek
               any contribution or reimbursement from any other Borrower or any
               other guarantor in respect of payments made by such Borrower
               hereunder, until all amounts owing to the Lenders and the Agent
               by the Borrowers on account of the Obligations are irrevocably
               paid in full; provided, however, that the Company may seek
               reimbursement from a Borrower for payments made by the Company on
               behalf of such Borrower if (i) all Obligations owing to the
               Lenders and the Agent by that Borrower are irrevocably paid in
               full and (ii) the Lenders have no further obligation to make
               Loans to enable such Borrower to originate Mortgage Loans. If any
               amount shall be paid to a Borrower on account of such subrogation
               rights at any time when all of the Obligations shall not have
               been irrevocably paid in full, such amount shall be held by that
               Borrower in trust for the Lenders and the Agent, segregated from
               other funds of that Borrower, and shall, forthwith upon receipt
               by the Borrower, be turned over to the Agent in the exact form
               received by the Borrower (duly indorsed by the Borrower to the
               Agent, if required), to be applied against the Obligations,
               whether matured or unmatured, in such order as the Agent may
               determine. From and after the irrevocable payment in full of all
               amounts owing to the Lenders and the Agent by the Borrowers on
               account of the Obligations, each Co-Borrower shall be liable to
               the Company for any amount paid by the Company to the Agent or
               the Lenders (and not previously paid to the Company by such
               Co-Borrower) as principal of and interest on the Loans and
               Swingline Loans made to enable such Co

                                      -14-



                     Borrowers to originate or acquire Mortgage Loans, fees,
                     costs and expenses relating to such Loans and Swingline
                     Loans, and such Co-Borrower's performance or
                     non-performance of its Obligations hereunder.

                            (f) Application of Payments. Any and all payments
                     upon the Obligations made by any Borrower, and/or the
                     proceeds of any or all collateral or security for any of
                     the Obligations provided by any Borrower, may be applied by
                     the Lenders on such items of the Obligations for which such
                     Borrower is liable as the Lenders may elect.

                            (g) Recovery of Payment. If any payment received by
                     the Lenders or the Agent and applied to the Obligations is
                     subsequently set aside, recovered, rescinded or required to
                     be returned for any reason (including, without limitation,
                     the bankruptcy, insolvency or reorganization of a Borrower
                     or any other obligor), the Obligations to which such
                     payment was applied shall, to the extent permitted by
                     applicable law, be deemed to have continued in existence,
                     notwithstanding such application, and each Borrower liable
                     on such Obligations shall be jointly and severally liable
                     for such Obligations as fully as if such application had
                     never been made. References in this Agreement to amounts
                     "irrevocably paid" or to "irrevocable payment" refer to
                     payments that cannot be set aside, recovered, rescinded or
                     required to be returned for any reason.

                            (h) Borrowers' Financial Condition. The Company is
                     familiar with the financial condition of each Co-Borrower,
                     each Co-Borrower is familiar with the financial condition
                     of the Company and each Borrower has executed and delivered
                     this Agreement based on that Borrower's own judgment and
                     not in reliance upon any statement or representation of the
                     Agent or any Lender. The Lenders and the Agent shall have
                     no obligation to provide any Borrower with any advice
                     whatsoever or to inform any Borrower at any time of the
                     Lenders' actions, evaluations or conclusions on the
                     financial condition or any other matter concerning the
                     Borrowers.

                            (i) Bankruptcy of the Borrowers. Each Borrower
                     expressly agrees that, to the extent permitted by
                     applicable law, the liabilities and obligations of that
                     Borrower under this Agreement shall not in any way be
                     impaired or otherwise affected by the institution by or
                     against any other Borrower or any other Person of any
                     bankruptcy, reorganization, arrangement, insolvency or
                     liquidation proceedings, or any other similar proceedings
                     for relief under any bankruptcy law or similar law for the
                     relief of debtors and that any discharge of any of the
                     Obligations pursuant to any such bankruptcy or similar law
                     or other law shall not diminish, discharge or otherwise
                     affect in any way the obligations of that Borrower under
                     this Agreement, and that upon the institution of any of the
                     above actions, such obligations shall be enforceable
                     against that Borrower.

                                      -15-



                          (j) Limitation; Insolvency Laws. As used in this
                     Section 10.17(j): (a) the term "Applicable Insolvency Laws"
                     means the laws of the United States of America or of any
                     State, province, nation or other governmental unit relating
                     to bankruptcy, reorganization, arrangement, adjustment of
                     debts, relief of debtors, dissolution, insolvency,
                     fraudulent transfers or conveyances or other similar laws
                     (including, without limitation, 11 U. S. C. 547, 548, 550
                     and other "avoidance" provisions of Title 11 of the United
                     Stated Code) as applicable in any proceeding in which the
                     validity and/or enforceability of this Agreement against
                     any Borrower, or any Specified Lien is in issue; and (b)
                     "Specified Lien" means any security interest, mortgage,
                     lien or encumbrance granted by any Borrower securing the
                     Obligations, in whole or in part. Notwithstanding any other
                     provision of this Agreement, if, in any proceeding, a court
                     of competent jurisdiction determines that with respect to
                     any Borrower, this Agreement or any Specified Lien would,
                     but for the operation of this Section, be subject to
                     avoidance and/or recovery or be unenforceable by reason of
                     Applicable Insolvency Laws, this Agreement and each such
                     Specified Lien shall be valid and enforceable against such
                     Borrower, only to the maximum extent that would not cause
                     this Agreement or such Specified Lien to be subject to
                     avoidance, recovery or unenforceability. To the extent that
                     any payment to, or realization by, the Lenders or the Agent
                     on the Obligations exceeds the limitations of this Section
                     and is otherwise subject to avoidance and recovery in any
                     such proceeding, the amount subject to avoidance shall in
                     all events be limited to the amount by which such actual
                     payment or realization exceeds such limitation, and this
                     Agreement as limited shall in all events remain in full
                     force and effect and be fully enforceable against such
                     Borrower. This Section is intended solely to reserve the
                     rights of the Lenders and the Agent hereunder against each
                     Borrower, in such proceeding to the maximum extent
                     permitted by Applicable Insolvency Laws and neither the
                     Borrowers, any guarantor of the Obligations nor any other
                     Person shall have any right, claim or defense under this
                     Section that would not otherwise be available under
                     Applicable Insolvency Laws in such proceeding.

              (q)    Schedule 1 to the Credit Agreement is hereby amended in its
       entirety to read as set forth on Schedule 1 hereto.

              (r)    Exhibits A, B and D to the Credit Agreement are hereby
       amended in their entirety to read as set forth on Exhibits A, B and D
       hereto.

              (s)    A new Exhibit E, in the form set forth on Exhibit E hereto,
       is added to the Credit Agreement.

                                      -16-



       3. Amendments to Pledge and Security Agreement. The Pledge and Security
Agreement is hereby amended as follows:

              (a) Except as otherwise provided in this Amendment, all references
       in the Pledge and Security Agreement to "the Borrower" shall mean and
       refer to "the Borrowers," "each Borrower," or "the applicable Borrower,"
       as the context may require. All references in Sections 5(n) and 10.04(a)
       of the Pledge and Security Agreement to "the Borrower" shall mean and
       refer to "the Company."

              (b) Section 3 of the Pledge and Security Agreement is hereby
       amended in its entirety to read as follows:

                  Section 3. REPORTS CONCERNING EXISTING COLLATERAL AND
              HEREAFTER ACQUIRED COLLATERAL. From time to time hereafter as
              reasonably requested by the Agent, the Company will promptly give
              a written report to the Agent describing and listing each
              document, instrument or other paper which evidences, secures,
              guarantees, insures or pertains to any item of the Collateral
              whether now or hereafter owned, acquired or held by the Borrowers.
              Such written report shall contain sufficient information to enable
              the Agent to identify each such document, instrument or other
              paper. The Company (a) upon the request of the Agent, shall
              promptly provide additional information concerning, or a more
              complete description of, each such document, instrument or other
              paper and (b) at the request of the Agent, shall promptly deliver
              the same to the Agent. The Co-Borrowers shall, at the request of
              the Company, cooperate with the Company in complying with the
              requirements of this Section 3.

              (c) Section 16 of the Pledge and Security Agreement is hereby
       amended in its entirety to read as follows:

                  Section 16. NOTICES. Reasonable notification of the time and
              place of any public sale of any Collateral, or reasonable
              notification of the time after which any private sale or other
              intended disposition of any of the Collateral is to be made shall
              be sent to the Company (with a copy to any applicable Co-Borrower)
              and to any other person entitled under the Code to notice;
              provided, that if any of the Collateral threatens to decline
              speedily in value, or is of a type customarily sold on a
              recognized market, the Agent may sell or otherwise dispose of the
              Collateral without notification, advertisement, or other notice of
              any kind. The Borrowers acknowledge and agree that Mortgage Loans
              are property of a type subject to widely distributed standard
              price quotations and Mortgage-backed Securities are property of a
              type ordinarily sold on a recognized market, and agrees that the
              Agent may purchase Mortgage Loans and Mortgage-backed Securities
              at a private sale thereof and may sell Mortgage-backed Securities
              without providing prior notice thereof to the Borrower. It is
              agreed that notice sent or given not less than ten (10) calendar
              days prior to the taking of the action to which the notice relates
              is reasonable notification and notice of the purposes of this
              Section 16. All notices and other communications provided for in
              this Agreement shall be given to the parties at their respective
              addresses set forth in

                                      -17-



            the Credit Agreement or, as to each such party, at such other
            address as shall be designated by such party in a written notice to
            the other parties in accordance with the Credit Agreement. All such
            notices and other communications shall be given by one or more of
            the means specified in Section 10.01 of the Credit Agreement and,
            upon being so given, shall be deemed to have been given as of the
            earliest time specified in said Section 10.01 for the means so used.
            Each Co-Borrower hereby authorizes the Agent to send all notices of
            sale of any Collateral to the Company, on behalf of such
            Co-Borrower, and the Company undertakes to provide such notices to
            the applicable Co-Borrower(s).

            (d)   Clause FIFTH of Section 17 of the Pledge and Security
       Agreement is hereby amended in its entirety to read as follows:

                  Fifth: the balance (if any) of such proceeds shall be paid to
            the Borrowers, their successors or assigns, or as a court of
            competent jurisdiction may direct, provided, that if such proceeds
            are not sufficient to satisfy the Obligations in full, the Company
            and, to the extent provided in Section 10.19 of the Credit
            Agreement, each Co-Borrower, shall remain liable to the Agent and
            the Lenders for any deficiency.

            (e)   Attachments 1, 2, 3, 5 and 6 to the Pledge and Security
       Agreement are hereby amended in their entirety to read as set forth on
       Attachments 1, 2, 3, 5 and 6 hereto.

       4. Exiting Lender. Effective as of December 12, 2001 (the "Exit Payoff
Date"), the Commitment Amount of First Union National Bank ("First Union") shall
terminate. If the outstanding principal balance of all Loans on the Exit Payoff
Date exceeds the sum of the Commitment Amounts, after giving effect to such
termination, the Company shall repay the Loans in the amount of such excess,
together with all interest, fees and other amounts payable to First Union, if
any, under the Credit Agreement as of the Exit Date. Provided there is no
Default or Event of Default or any other failure to satisfy the conditions
pursuant to Loans under the Credit Agreement on the Exit Date, the Agent shall
request that each of the Lenders (other than First Union) make Loans on the Exit
Date in the amount, if any, required to increase its outstanding Loans to its
Percentage Share of all outstanding Loans, and shall deliver the proceeds of
such Loans to the Agent; provided, however, that should any Lender fail to make
such Loans on the Exit Date, the Company shall repay the Loans in the amount
that such Lender failed to deliver to the Agent. The aggregate unpaid principal
amount of the Loans made by First Union under the Credit Agreement, together
with all interest, fees and other amounts, if any, payable to First Union under
the Credit Agreement as of the Exit Date (the "Payoff Amount"), shall be repaid
in full from the funds provided by the Company and the proceeds of Loans made by
the other Lenders. The Agent shall distribute to First Union by not later than
3:00 P.M. (Minneapolis time) on the Exit Date out of the proceeds of the funds
provided by the Company and the Loans made by the other Lenders for such
purpose, the amount required to pay First Union's Payoff Amount in full,
whereupon: (a) First Union shall no longer be a party to the Credit Agreement;
and (b) First Union shall not be deemed to be a "Lender" for any purpose under
the Credit Agreement.

                                      -18-



       5. Conditions to Effectiveness of this Amendment. This Amendment shall

              form of Exhibit A hereto, in the amount of such Lender's
              respective Commitment Amount (each, a "New Note"), duly executed
              by the Company;

                  (ii)  copy of resolutions of the Board of Directors of the
              Company, certified by its respective Secretary or Assistant
              Secretary, authorizing or ratifying the execution, delivery and

              (e) Each of the Lenders shall have received an upfront fee in the
       amount set forth on Schedule 6 to this Amendment.

              (f) The Agent shall have received the amendment fee required by
       Section 10.02 of the Credit Agreement.

                                      -19-

amended hereby, the Credit Agreement and the Pledge and Security Agreement
remain in full force and effect with respect to the Company and the Lenders, and

            (a)   The Company agrees to reimburse the Agent upon demand for all

       furnished herewith, and to pay and save the Lenders harmless from all
       liability for any stamp or other taxes which may be payable with respect
