                                    COVENANTS


                  The following additional covenants will apply with respect to
the Notes:

Section 4.01. Restrictions on Secured Debt.

                  The Company will not, and will not cause or permit a
Restricted Subsidiary (other than any Finance Subsidiary) to, create, incur,
assume or guarantee any Secured Debt unless the Notes will be secured equally
and ratably with (or prior to) such Secured Debt, with certain exceptions. This
restriction does not prohibit the creation, incurrence, assumption or guarantee
of Secured Debt which is secured by:

                  (1) Security Interests in model homes, homes held for sale,
         homes that are under contract for sale, contracts for the sale of
         homes, land (improved or unimproved), manufacturing plants, warehouses
         or office buildings and fixtures and equipment located thereat or
         thereon;


<PAGE>
                                      -12-


                  (2) Security Interests in property at the time of its
         acquisition by the Company or a Restricted Subsidiary, including
         Capitalized Lease Obligations, which Security Interests secure
         obligations assumed by the Company or a Restricted Subsidiary, or in
         the property of a corporation or other entity at the time it is merged
         into or consolidated with the Company or a Restricted Subsidiary (other
         than Secured Debt created in contemplation of the acquisition of such
         property or the consummation of such a merger or where the Security
         Interest attaches to or affects the property of the Company or a
         Restricted Subsidiary prior to such transaction);

                  (3) Security Interests arising from conditional sales
         agreements or title retention agreements with respect to property
         acquired by the Company or a Restricted Subsidiary;

                  (4) Security Interests incurred in connection with pollution
         control, industrial revenue, water, sewage or any similar item; and

                  (5) Security Interests securing Indebtedness of a Restricted
         Subsidiary owing to the Company or a Restricted Subsidiary that is
         wholly owned (directly or indirectly) by the Company or Security
         Interests securing the Company's Indebtedness owing to a Guarantor.

                  Such permitted Secured Debt also includes any amendment,
restatement, supplement, renewal, replacement, extension or refunding, in whole
or in part, of Secured Debt permitted at the time of the original incurrence
thereof.

                  In addition, the Company and the Guarantors may create, incur,
assume or guarantee Secured Debt, without equally and ratably securing the
Notes, if immediately thereafter the sum of (1) the aggregate principal amount
of all Secured Debt outstanding (excluding Secured Debt permitted under clauses
(1) through (5) above and any Secured Debt in relation to which the Notes have
been equally and ratably secured) and (2) all Attributable Debt in respect of
Sale and Leaseback Transactions (excluding Attributable Debt in respect of Sale
and Leaseback Transactions as to which the provisions of clauses (1) through (3)
under Section 4.02 have been complied with) as of the date of determination
would not exceed 20% of Consolidated Net Tangible Assets.

                  The provisions described above with respect to limitations on
Secured Debt are not applicable to Non-Recourse Indebtedness by virtue of the
definition of Secured Debt, and will not restrict the Company's or the
Guarantors' ability to create, incur, assume or guarantee


<PAGE>
                                      -13-


any unsecured Indebtedness, or of any Subsidiary which is not a Restricted
Subsidiary to create, incur, assume or guarantee any secured or unsecured
Indebtedness.

Section 4.02. Limitations on Sale and Leaseback Transactions.

                  The Company will not, and will not cause or permit any
Restricted Subsidiary to, enter into any Sale and Leaseback Transaction unless
(1) the net proceeds to the Company or such Restricted Subsidiary from such sale
or transfer equal or exceed the fair value (as determined by the Board of
Directors, chairman of the board, vice chairman, president or principal
financial officer of the Company) of the property or asset so leased, (2) the
Company or such Restricted Subsidiary would be entitled to incur Secured Debt
pursuant to Section 4.01, (3) the Company or any Restricted Subsidiary shall,
and in any case the Company and the Restricted Subsidiaries, covenant that they
will, within 180 days of the effective date of any Sale and Leaseback
Transaction, apply an amount equal to the fair value of the property so leased
to the retirement of Funded Indebtedness, (4) the Sale and Leaseback Transaction
relates to a sale which occurred within 180 days from the date of acquisition of
such property or asset by the Company or a Restricted Subsidiary or the date of
the completion of construction or commencement of full operations on such
property, whichever is later, or (5) the Sale and Leaseback Transaction was
consummated prior to the date of this Supplemental Indenture.

Section 4.03. Additional Guarantees.

                  The Company shall not permit any Subsidiary that is not a
Guarantor, directly or indirectly, to guarantee any obligations of the Company
under the Specified Indebtedness unless such Subsidiary simultaneously executes
and delivers to the Trustee a supplemental indenture, in a form reasonably
satisfactory to the Trustee, pursuant to which such Subsidiary guarantees,
jointly and severally with all other Guarantors, on the same basis as the
Specified Indebtedness is guaranteed, the Company's obligations under the
Indenture and the Notes. The Company shall deliver to the Trustee an opinion of
counsel that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary and, subject to customary exceptions, constitutes a
valid and legally binding and enforceable obligation of such Subsidiary.

Section 4.04. SEC Reports.

                  The Company shall deliver to the Trustee and each Holder,
within 15 days after it files the same with the SEC, copies of all reports and
information (or copies of such portions of any of the foregoing as the SEC may
by rules and regulations prescribe), if any, exclusive of exhibits, which the
Company is required to file with the SEC pursuant to Section 13 or 15(d) of the
Exchange Act or pursuant to the immediately following sentence. So long as any
Notes remain outstanding, the Company shall file with the Commission such
reports as may be required pursuant to Section 13 of the Exchange Act in respect
of a security registered


<PAGE>
                                      -14-


pursuant to Section 12 of the Exchange Act. If the Company is not subject to the
requirements of Section 13 or 15(d) of the Exchange Act (or otherwise required
to file reports pursuant to the immediately preceding sentence), the Company
shall deliver to the Trustee and to each Holder, within 15 days after it would
have been required to file such information with the SEC were it required to do
so, financial statements, including any notes thereto (and, in the case of a
fiscal year end, an auditors' report by an independent certified public
accounting firm of established national reputation), and a "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
substantially equivalent to that which it would have been required to include in
such quarterly or annual reports, information, documents or other reports if it
had been subject to the requirements of Section 13 or 15(d) of the Exchange Act.
The Company shall also comply with the other provisions of TIA Section 314(a).

                  The Trustee has no duty to review the financial reports and
other information for the purpose of determining compliance with any provision
of this Indenture.


                                  ARTICLE FIVE

                              SUCCESSOR CORPORATION


                  Article Five of the Indenture is replaced with the following
in its entirety:

Section 5.01. Consolidation, Merger and Sale of Assets.

                  Neither the Company nor the Guarantors will consolidate or

                  (1) the person is a corporation organized under the laws of
         the United States of America or any state thereof;

                  (2) the person assumes by supplemental indenture, in a form
         reasonably satisfactory to the Trustee, all of the obligations of the
         Company or such Guarantor, as the case may be, relating to the Notes,
         the Guarantees and the Indenture, as the case may be; and

                  (3) immediately after the transaction no Event of Default
         exists; provided that this clause (3) will not restrict or be
         applicable to a merger, consolidation or liquidation of a Guarantor
         with or into the Company or another Subsidiary that is wholly owned,
         directly or indirectly, by the Company that is, or concurrently with
         the completion of such merger, consolidation or liquidation becomes, a
         Guarantor or a Restricted Subsidiary that is wholly owned, directly or
         indirectly, by the Company.


<PAGE>
                                      -15-


                  Upon any such consolidation, merger, sale, assignment or
transfer, the successor corporation will be substituted for the Company or such
Guarantor (including any merger or consolidation described in the proviso at the
end of the immediately preceding sentence), as applicable, under the Indenture.
The successor corporation may then exercise every power and right of the Company
or such Guarantor under the Indenture, and the Company or such Guarantor, as
applicable, will be released from all of its respective liabilities and
obligations in respect of the Notes and the Indenture. If the Company or any
Guarantor leases all or substantially all of its assets, the lessee corporation
will be the successor to the Company or such Guarantor and may exercise every
power and right of the Company or such Guarantor, as the case may be, under the
Indenture, but the Company or such Guarantor, as the case may be, will not be
released from its respective obligations to pay the principal of and premium, if
any, and interest, if any, on the Notes.


                                   ARTICLE SIX

                                   GUARANTEES


Section 6.01. Unconditional Guarantee.

                  Each Guarantor hereby fully and unconditionally, jointly and
severally, guarantees (each such guarantee to be referred to herein as the
"Guarantee") to the Holders of the Notes and to the Trustee and its successors
and assigns that: (i) the principal of and interest on the Notes will be
promptly paid in full when due, subject to any applicable grace period, whether
at maturity, by acceleration or otherwise and interest on the overdue principal,
if any, and interest on any interest of the Notes and all other obligations of
the Company to the Holders or the Trustee hereunder or thereunder will be
promptly paid in full or performed, all in accordance with the terms hereof and
thereof; and (ii) in case of any extension of time of payment or renewal of any
Notes or of any such other obligations, the same will be promptly paid in full
when due or performed in accordance with the terms of the extension or renewal,
subject to any applicable grace period, whether at stated maturity, by
acceleration or otherwise (collectively, the "Guaranteed Obligations"), subject,
however, in the case of clauses (i) and (ii) above, to the limitations set forth
in Section 6.02. Each Guarantor hereby agrees that its obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or the Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of Notes with respect to
any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a guarantor.


<PAGE>
                                      -16-


                  The obligations of the Guarantors hereunder are separate and
independent of the obligations of the Company and of any other guarantor, and a
separate action or actions may be brought and prosecuted against the Guarantor
whether action is brought against the Company or any other guarantor or whether
the Company or any other guarantor is joined in any action or actions. The
obligations of the Guarantor hereunder shall survive and continue in full force
and effect until the earlier of (i) such time as the Guarantor may be released
from its obligations hereunder pursuant to the terms Section 6.06 hereof, or
(ii) payment in full of the Guaranteed Obligations is actually received by the
Holders or the Trustee on behalf of the Holders and the period of time has
expired during which any payment made by the Company or the Guarantor may be
determined to be a Preferential Payment (defined below), notwithstanding any
release or termination of the Company's or any other Guarantor's liability by
express or implied agreement or by operation of law and notwithstanding that the
Guaranteed Obligations or any part thereof are deemed to have been paid or
discharged by operation of law or by some act or agreement. For purposes of this
Guarantee, the Guaranteed Obligations shall be deemed to be paid only to the
extent that the Holders, or the Trustee on behalf of the Holders, actually
receive immediately available funds.

                  The Guarantors agree that to the extent the Company or any
other guarantor makes any payment to the Holders, or to the Trustee on behalf of
the Holders, in connection with the Guaranteed Obligations, and all or any part
of such payment is subsequently invalidated, declared to be fraudulent or
preferential, set aside or required to be repaid by the Holders or the Trustee
or paid over to a trustee, receiver or any other entity, whether under any
bankruptcy act or otherwise (any such payment is hereinafter referred to as a
"Preferential Payment"), then this Guarantee shall continue to be effective or
shall be reinstated, as the case may be, and, to the extent of such payment or
repayment by the Holders or Trustee, the Guaranteed Obligations or part thereof
intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
made.

Section 6.02. Fraudulent Conveyance Limitation.

                  Notwithstanding any contrary provision, the amount of the
Guaranteed Obligations guaranteed by the Guarantor under this Guarantee shall
be, but not in excess of, the maximum amount permitted by fraudulent conveyance,
fraudulent transfer or similar laws applicable to the Guarantor. Accordingly,
notwithstanding anything to the contrary contained in this Guarantee or any
other agreement or instrument executed in connection with the payment of the
Guaranteed Obligations, the amount of the Guaranteed Obligations guaranteed by
the Guarantor by this Guarantee shall be limited to an aggregate amount equal to
the largest amount that would not render the Guarantor's obligations hereunder
subject to avoidance under any Bankruptcy Law.


<PAGE>
                                      -17-


Section 6.03. Waiver.

                  Each Guarantor waives and agrees not to assert: (a) any right
to require the Holders or Trustee to proceed against the Company or any other
guarantor, to proceed against or exhaust any security for the Guaranteed
Obligations, to pursue any other remedy available to the Holders or Trustee or
to pursue any remedy in any particular order or manner; (b) the benefit of any
statute of limitations affecting Guarantor's liability hereunder or the
enforcement hereof; (c) demand, diligence, presentment for payment, protest and
demand, and notice of extension, dishonor, protest, demand, nonpayment and
acceptance of this Guarantee; (d) notice of the existence, creation or incurring
of new or additional indebtedness of the Company to the Holders; and (e) any
defense arising by reason of any disability or other defense of the Company or
by reason of the cessation from any cause whatsoever (other than payment in full
of all amounts demanded to be paid by the Guarantor under this Guarantee) of the
liability of the Company for the Guaranteed Obligations. Each Guarantor hereby
expressly consents to any impairment of collateral, including, but not limited
to, failure to perfect a security interest and release collateral and any such
impairment or release shall not affect Guarantors' obligations hereunder. Until
payment in full of the Guaranteed Obligations, no Guarantor shall have a right
of subrogation and hereby waives any right to enforce any remedy which the
Holders or the Trustee now have, or may hereafter have, against the Company, and
waives any benefit of, any right to participate in, any security now or
hereafter held on behalf of the Holders.

Section 6.04. Subordinated Indebtedness.

                  If from time to time the Company shall have liabilities or
obligations to the Guarantors, whether absolute or contingent, joint, several,
or joint and several, such liabilities and obligations (the "Subordinated
Indebtedness") and any and all assignments as security, grants in trust, liens,
mortgages, security interests, other encumbrances, and other interests and
rights securing such liabilities and obligations shall at all times be fully
subordinate to payment and performance in full of the Guaranteed Obligations.
Each Guarantor agrees that such liabilities and obligations of the Company to
Guarantor shall not be secured by any assignment as security, grant in trust,
lien, mortgage, security interest, other encumbrance or other interest or right
in any property, interests in property, or rights to property of the Company.
Each Guarantor agrees that (i) so long as no Event of Default has occurred and
is continuing, payments of principal and interest on the Subordinated
Indebtedness may be made by the Company and accepted by Guarantor as such
payments become due; and (ii) after the occurrence and during the continuation
of an Event of Default, the Company shall not make and Guarantor shall not
accept any payments with respect to the Subordinated Indebtedness. If,
notwithstanding the foregoing, subsequent to an Event of Default, Guarantor
receives any payment from the Company, such payment shall be held in trust by
Guarantor for the benefit of the Holders, and shall be segregated from the other
funds of Guarantor, and shall forthwith


<PAGE>
                                      -18-


be paid by Guarantor to the Holders or to the Trustee on behalf of the Holders
and applied to payment of the Guaranteed Obligations whether or not then due.

                  In the event of any distribution, division, or application,
partial or complete, voluntary or involuntary, by operation of law or otherwise,
of all or any part of the assets of the Company, or the proceeds thereof, to
creditors of the Company, by reason of the liquidation, dissolution, or other
winding up of the Company's business, or in the event of any receivership,
insolvency or bankruptcy proceedings by or against the Company, or assignment
for the benefit of creditors, or of any proceedings by or against the Company
for any relief under any bankruptcy or insolvency laws, or relating to the
relief of debtors, readjustment of indebtedness, reorganizations, arrangements,
compositions or extensions, or of any other event whereby it becomes necessary
or desirable to file or present claims against the Company for the purpose of
receiving payment thereof, or on account thereof, then and in any such event,
any payment or distribution of any kind or character, either in cash or other
property, which shall be made or shall be payable with respect to any
Subordinated Indebtedness shall be paid over to the Holders or to the Trustee on
behalf of the Holders for application to the payment of the Guaranteed
Obligations, whether due or not due, and no payments shall be made upon or in
respect of the Subordinated Indebtedness unless and until the Guaranteed
Obligations shall have been paid and satisfied in full. In any such event, all
claims of the Holders and all claims of Guarantor shall, at the option of the
Trustee, forthwith become due and payable without demand or notice.

                  In the event of any distribution, division, or application,
partial or complete, voluntary or involuntary, by operation of law or otherwise,
of all or any part of the assets of the Company, or the proceeds thereof, to
creditors of the Company, by reason of the liquidation, dissolution, or other
winding up of the Company's business, or in the event of any receivership,
insolvency or bankruptcy proceedings by or against the Company, or assignment
for the benefit of creditors, or of any proceedings by or against the Company
for any relief under any bankruptcy or insolvency laws, or relating to the
relief of debtors, readjustment of indebtedness, reorganizations, arrangements,
compositions or extensions, or of any other event whereby it becomes necessary
or desirable to file or present claims against the Company for the purpose of
receiving payment thereof, or on account thereof, each Guarantor irrevocably
authorizes and empowers the Trustee, or any person the Trustee may designate, to
act as attorney for Guarantor with full power and authority in the name of
Guarantor, or otherwise, to make and present such claims or proofs of claims
against the Company on account of the Subordinated Indebtedness as the Trustee,
or its appointee, may deem expedient and proper and, if necessary, to vote such
claims in any proceedings and to receive and collect for the benefit of the
Holders any and all dividends or other payments and disbursements made thereon
in whatever form they may be paid or issued, and to give acquittance therefor
and to apply same to the Guaranteed Obligations, and each Guarantor hereby
agrees, from time to time and upon request, to make, execute and deliver to the
Trustee such powers of attorney,

                                      -19-


assignments, endorsements, proofs of claim, pleadings, verifications,
affidavits, consents, agreements or other instruments as may be requested by the
Trustee in order to enable the Trustee and the Holders to enforce any and all
claims upon, or with respect to, the Subordinated Indebtedness, and to collect
and receive any and all payments or distributions which may be payable or
deliverable at any time upon or with respect to the Subordinated Indebtedness.

                  Except as otherwise permitted herein, should any payment or
distribution or security or proceeds thereof be received by a Guarantor upon or
with respect to the Subordinated Indebtedness prior to the satisfaction of the
Guaranteed Obligations, such Guarantor will forthwith deliver the same to the
Trustee on behalf of the Holders in precisely the form as received except for
the endorsement or assignment of the Guarantor where necessary for application
on the Guaranteed Obligations, whether due or not due, and until so delivered
the same shall be held in trust by Guarantor as property of the Trustee on
behalf of the Holders. In the event of the failure of Guarantor to make any such
endorsement or assignment, the Trustee, or any of its officers or employees, on
behalf of the Trustee, is hereby irrevocably authorized to make the same.

                  Each Guarantor agrees to maintain in its records notations
satisfactory to the Trustee of the rights and priorities of the Holders
hereunder, and from time to time, upon request, to furnish the Trustee for the
benefit of the Holders with sworn financial statements. The Trustee may inspect
the books of account and any records of each Guarantor at any time during
business hours. Each Guarantor agrees that any promissory note now or hereafter
evidencing the Subordinated Indebtedness shall be nonnegotiable and shall be
marked with a specific statement that the indebtedness thereby evidenced is
subject to the provisions of this Guarantee.

Section 6.05. Execution of Guarantee.

                  Each Guarantor hereby agrees to execute a notation of
Guarantee in substantially the form attached to the form of Note, and to deliver
such notation to the Trustee.

Section 6.06. Additional Guarantees and Release of Guarantees.

                  (a) The Company shall not permit any of its Restricted
Subsidiaries, directly or indirectly, to guarantee any Specified Indebtedness
("Guaranteed Indebtedness") unless such Restricted Subsidiary simultaneously
executes and delivers to the Trustee a supplemental indenture, in a form
reasonably satisfactory to the Trustee, pursuant to which such Restricted
Subsidiary guarantees, jointly and severally with all other Guarantors, on the
same basis as such Guaranteed Indebtedness is guaranteed, the Guaranteed
Obligations. If the Guaranteed Indebtedness (1) ranks pari passu in right of
payment with the Notes, then the guarantee of such Guaranteed Indebtedness shall
rank pari passu with, or be subordinated in


<PAGE>
                                      -20-


right of payment to, the Guarantee of such Restricted Subsidiary or (2) is
subordinated by its terms in right of payment to the Notes, then the guarantee
of such Guaranteed Indebtedness shall be subordinated to the Guarantee of such
Restricted Subsidiary at least to the extent that the Guaranteed Indebtedness is
subordinated to the Notes.

                  (b) The Guarantee of any Guarantor will be automatically and
unconditionally released and discharged so long as:

                           (i) no Default or Event of Default exists or would
                  result from release of such Guarantee;

                           (ii) the Guarantor being released has Consolidated
                  Net Worth of less than 5% of the Company Consolidated Net
                  Worth as of the end of the most recent fiscal quarter;

                           (iii) the Guarantors released from their Guarantees
                  in any year-end period comprise in the aggregate less than 10%
                  (or 15% if and to the extent necessary to permit the Company
                  to cure a Default) of the Company's Consolidated Net Worth as
                  of the end of the most recent fiscal quarter;

                           (iv) such release would not have a material adverse
                  effect on the homebuilding business of the Company and its
                  Subsidiaries; and

                           (v) the Guarantor is released from its guarantee(s)
                  under the Specified Indebtedness;

provided, in each such case, the Company has delivered to the Trustee an
Officers' Certificate and Opinion of Counsel, each stating that all conditions
precedent provided for in the Indenture relating to such transactions have been
complied with and that such release is authorized and permitted under the
Indenture.

                  (c) If there are no guarantors under any Specified
Indebtedness, Guarantors under this Indenture Supplement will be released from
their Guarantees.

                              M.D.C. HOLDINGS, INC.
                           7.0% Senior Notes due 2012

1. Interest.

                  M.D.C. HOLDINGS, INC. (the "Company"), a Delaware corporation,
promises to pay interest on the principal amount of this Note at the rate per
annum shown above. The Company will pay interest semiannually on June 1 and
December 1 of each year until the principal is paid or made available for
payment. Interest on the Notes will accrue from the most recent date to which
interest has been paid or duly provided for or, if no interest has been paid,
from December 3, 2002; provided that, if there is no existing default in the
payment of interest, and if this Note is authenticated between a record date
referred to on the face hereof and the next succeeding interest payment date,
interest shall accrue from such interest payment date. Interest will be computed
on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment.

                  The Company will pay interest on the Notes (except defaulted
interest, if any, which will be paid on such special payment date to Holders of
record on such special record date as may be fixed by the Company) on each
Interest Payment Date to the persons who are registered Holders of Notes at the
close of business on the May 15 and November 15 preceding such Interest Payment
Date. Holders must surrender Notes to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.

3. Paying Agent and Registrar.

                  Initially, U.S. Bank National Association (the "Trustee") will
act as Paying Agent and Registrar. The Company may change or appoint any Paying
Agent, Registrar or co-Registrar without notice. The Company or any of its
Subsidiaries may act as Paying Agent, Registrar or co-Registrar.

4. Indenture.

                  The Company issued the Notes under an Indenture dated as of
December 3, 2002 between the Company and the Trustee, as supplemented by a
Supplemental Indenture dated as of December 3, 2002 among the Company, the
Guarantors and the Trustee (together, the "Indenture"). The terms of the Notes
and the Guarantees include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 ("TIA") as in
effect on the date of the Indenture. The Notes and the Guarantees are subject to
all such terms, and Holders are referred to the Indenture and the TIA for a
statement of them.



                                      A-4
<PAGE>

                  The Company will furnish to any Holder upon written request
and without charge a copy of the Indenture. Requests may be made to: M.D.C.
Holdings, Inc., 3600 South Yosemite, Suite 900, Denver, Colorado 80237,
Attention: Secretary.

5. Optional Redemption.

                  The Notes will be redeemable at the option of the Company, in
whole at any time or in part from time to time, on at least 30 but not more than
60 days' prior notice, at a Redemption Price equal to the greater of (i) 100% of
their principal amount, and (ii) the present value of the Remaining Scheduled
Payments on the Notes being redeemed on the Redemption Date, discounted to the
Redemption Date, on a semiannual basis, at the Treasury Rate plus 45 basis
points (0.45%), plus, in each case, accrued and unpaid interest on the Notes to
the Redemption Date. In determining the Redemption Price and accrued interest,
interest shall be calculated on the basis of a 360-day year consisting of twelve
30-day months.

                  Notice of redemption will be mailed at least 30 days but not
more than 60 days before the Redemption Date to each Holder of Notes to be
redeemed at his registered address. Notes in denominations larger than $1,000
may be redeemed in part. On and after the Redemption Date, interest ceases to
accrue on Notes or portions of them called for redemption; provided that if the
Company shall default in the payment of such Note at the redemption price
together with accrued interest, interest shall continue to accrue at the rate
borne by the Notes.

6. Denominations, Transfer, Exchange.

                  The Notes are in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000. A Holder may transfer
or exchange Notes by presentation of such Notes to the Registrar or a
co-Registrar with a request to register the transfer or to exchange them for an
equal principal amount of Notes of other denominations. The Registrar may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not transfer or exchange any Note selected for
redemption, except the unredeemed part thereof if the Note is redeemed in part,
or transfer or exchange any Notes for a period of 15 days before a selection of
Notes to be redeemed.

7. Persons Deemed Owners.

                  The registered Holder of this Note shall be treated as the
owner of it for all purposes.



                                      A-5
<PAGE>

8. Unclaimed Money.

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent will pay the money back to
the Company at its request. After that, Holders entitled to the money must look
to the Company for payment unless an abandoned property law designates another
person.

9. Amendment, Supplement, Waiver.

                  Subject to certain exceptions, the Indenture or the Notes may
be amended or supplemented with the consent of the Holders of at least a
majority in principal amount of the outstanding Notes and any past default or
compliance with any provision relating to the Notes may be waived in a
particular instance with the consent of the Holders of a majority in principal
amount of the outstanding Notes. Without the consent of any Holder, the Company
and the Trustee may amend or supplement the Indenture or the Notes to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to remove a Guarantor which, in
accordance with the terms of the Supplemental Indenture, ceases to be liable in
respect of its Guarantee, or to make any other change, provided such action does
not adversely affect the rights of any Holder.

10. Successor Corporation.

                  When a successor corporation assumes all the obligations of
its predecessor under the Notes and the Indenture, the predecessor corporation
will be released from those obligations, except that a lease of all or
substantially all its assets does not release the predecessor from its
obligations to pay the principal of and premium, if any, and interest, if any,
on the Notes.

11. Trustee Dealings With Company.

                  U.S. Bank National Association, the Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its Affiliates, and may
