     Reference is made to (i) the Note Agreement dated as of December 2, 1994
(as amended by that certain Letter Amendment dated as of February 15, 1996 and
that certain Letter Amendment dated as of December 30, 1996, the "1994
Agreement") among Principal Mutual Life Insurance Company ("Principal"),
Northern Life Insurance Company ("Northern"), Modern Woodmen of America ("MWA")
and Royal Neighbors of America ("RNA", and together with Principal, Northern and
MWA, collectively the "1994 Purchasers") and The Rottlund Company, Inc., a
Minnesota corporation (the "Company"), pursuant to which the 1994 Purchasers
purchased promissory notes of the Company in the aggregate original principal
amount of $25,000,000 (collectively, the "1994 Notes") and (ii) the Note
Agreement dated as of February 15, 1996 (as amended by that certain Letter

Services Life Insurance Company, n/k/a ReliaStar United Services Life Insurance
Company ("United", and together with Principal and Bankers, collectively the

(collectively, the "1996 Notes"). Capitalized terms used and not otherwise
defined herein shall have the meanings ascribed thereto in each Agreement.

     The Company has advised the Purchasers that the Company is at present in
default under Sections 5.5, 5.6 and 5.16 of each of the Agreements, which
defaults the Company hereby acknowledges. The Company has further advised the
Purchasers that the Company is likely to continue to be so in default under
Sections 5.5 and 5.16 of each of the Agreements in the near future. The Company
has accordingly requested certain waivers relating to Sections 5.5, 5.6 and 5.16
of each of the Agreements, and certain amendments relating to Sections 5.5 and
5.16 of each of the Agreements.

     In consideration of the premises herein set forth, and of other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, it is hereby agreed as follows:

<PAGE>

          1.   The Purchasers hereby waive the defaults existing as of the date
     hereof under Sections 5.5, 5.6 and 5.16 of each of the Agreements, and each
     Event of Default rising directly therefrom.

          2.   Section 5.5 of each of the Agreements is hereby amended and
     restated in its entirety as follows:

               The Company shall at all times maintain Consolidated Tangible Net
          Worth in an amount not less than $24,750,000 PLUS 70% of the positive
          Consolidated Net Income, if any, for each Fiscal Quarter commencing on
          or after April 1, 1997.

          3.   Section 5.13 of each Agreement is hereby amended by (i) changing
     the lettering of subsection (i) to (j), and (ii) adding thereto the
     following new subsection (i):

               (i)  LEVERAGE RATIO CERTIFICATES. As soon as available and in any
          event within 15 days after the close of any Fiscal Quarter, a Leverage
          Ratio Certificate, correctly setting forth the ratio, as of the close
          of such Fiscal Quarter, of (A) the sum of Consolidated Current Debt
          and Consolidated Funded Debt to (B) Consolidated Net Tangible Assets,
          all in reasonable detail and certified as complete and correct by a
          financial officer of the Company; and

          4.   Section 5.16 of each of the Agreements is hereby amended and
     restated in its entirety as follows:

               The Company shall maintain, as of the close of each month, Net
          Income Available for Fixed Charges for the immediately preceding
          twelve-month period of at least the following percentages of Fixed
          Charges for such twelve-month period:

               125% as of the close of each month on and prior to September 30,
               1997;

               145% as of the close of each month on and prior to February 28,
               1998; and

               200% as of the close of each month thereafter.

     As an inducement to and in consideration of the agreement by the Purchasers
to waive the defaults under the Agreements specified in Section 1 of this Waiver
and Amendment and to amend the Agreements as set forth in Sections 2, 3 and 4 of
this Waiver and Amendment, the Company hereby agrees, notwithstanding anything
in the Agreements, the 1994 Notes or the 1996 Notes (as the case may be) to the
contrary, as follows:

          (i)  if as of the close of any Fiscal Quarter commencing on or after
          April 1, 1997 the ratio of (A) the sum of Consolidated Current Debt
          and Consolidated Funded Debt to (B) Consolidated Net Tangible Assets
          (such ratio being herein referred to as the "Leverage Ratio"), as
          disclosed in the Leverage Ratio Certificate 


                                      2

<PAGE>

          referred to in Section 5.13(i) of each of the Agreements (each a 
          "Leverage Ratio Certificate") for such Fiscal Quarter, equals or 
          exceeds 64%, or if the Company fails to deliver the Leverage Ratio 
          Certificate for such Fiscal Quarter to the Holders in accordance 
          with Section 5.13(i) of each of the Agreements (and, in such event, 
          in addition to any other rights the Holders may exercise under 
          Section 6 of each Agreement), then, effective as of the first day 
          of the Fiscal Quarter immediately following the Fiscal Quarter to 
          which the Leverage Ratio Certificate applies (where the Company 
          delivers such Leverage Ratio Certificate) or would apply (where the 
          Company fails to do so), as the case may be, the 1994 Notes shall 
          bear interest at the rate of 12.61 % per annum and the 1996 Notes 
          shall bear interest at the rate of 9.92% per annum;

          (ii) if as of the close of any Fiscal Quarter commencing on or after
          April 1, 1997 the Leverage Ratio, as disclosed in the Leverage Ratio
          Certificate for such Fiscal Quarter, equals or exceeds 60% but is less
          than 64%, then, effective as of the first day of the Fiscal Quarter
          immediately following the Fiscal Quarter to which the Leverage Ratio
          Certificate applies, the 1994 Notes shall bear interest at the rate of
          12.36% per annum and the 1996 Notes shall bear interest at the rate of
          9.67% per annum; and

          (iii)     if as of the close of any Fiscal Quarter commencing on or
          after April 1, 1997 the Leverage Ratio, as disclosed in the Leverage
          Ratio Certificate for such Fiscal Quarter, is less than 60%, then,
          effective as of the first day of the Fiscal Quarter immediately
          following the Fiscal Quarter to which the Leverage Ratio Certificate
          applies, the 1994 Notes shall bear interest at the rate of 12.11 % per
          annum and the 1996 Notes shall bear interest at the rate of 9.42% per
          annum.

The amount of each combined installment of principal and interest payable on the
1994 Notes or the 1996 Notes, as the case may be, shall be adjusted to reflect
the foregoing arrangements, but the portion of each such combined installment
allocable to principal shall remain unchanged. Default in the payment of
interest, as calculated in accordance with the foregoing arrangements, shall
constitute an Event of Default under Section 6.1 of each of the Agreements. The
Company hereby agrees to execute, at the request of the Holders or any of them,
addenda to the 1994 Notes and the 1996 Notes evidencing the foregoing
arrangements.

     Except as specifically amended hereby, all terms and conditions of each of
the Agreements shall remain in full force and effect. This Waiver and Agreement
may be executed simultaneously in two or more counterparts, each of which shall
be an original, but all of which constitute but one agreement. This Waiver and
Amendment shall be governed by, and enforced in accordance with Minnesota law.

     The Company represents and warrants to the Purchasers that (i) except as
disclosed herein, no Default or Event of Default has occurred and is continuing,
(ii) this Waiver and Amendment has been duly authorized, executed and delivered
by the Company and each Agreement, as amended by this Waiver and Amendment,
constitutes a legal, valid and binding 


                                      3

obligation of the Company, and (iii) there is no provision in the Articles of 
Incorporation of the Company or in its bylaws or in any indenture, contract 
or agreement to which the Company is a party or by which it is bound nor any 
provision of law or any order of any court or governmental authority which 
prohibits the execution and delivery by the Company of this Waiver and 
Amendment, the performance or observance by the Company of the terms and 
conditions of this Waiver and Amendment, or the performance or observance by 
the Company of the terms and conditions of the Agreements, as modified by the 
amendments set forth in this Waiver and Amendment. All representations and 
warranties contained herein or made in writing by the Company in connection 
herewith shall survive the execution and delivery hereof. It shall be deemed 
to be an Event of Default under each Agreement if any of such representations 
or warranties proves to be false in any material respect as of the date 
hereof.

     If you are in agreement with the foregoing, please so indicate by executing
the form of acknowledgment set forth below, whereupon this Waiver and Amendment
shall become a binding agreement among you and the Company.
                                          
                              Very truly yours

                                  THE ROTTLUND COMPANY, INC.
