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 merge into or sell, assign, transfer or lease all or substantially all of their assets to another person unless:

(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.

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

-16-

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 hereof. 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.

The obligations of each Guarantor 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 a 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 each Guarantor hereunder shall survive and continue in full force and effect until the earlier of (i) such time as such Guarantor may be released from its obligations hereunder pursuant to the terms set forth in Section 6.06 hereof, or (ii)

-17-

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 such 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.

Each Guarantor agrees 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 the 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 each 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 such 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 any Guarantor by this Guarantee shall be limited to an aggregate amount equal to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under any Bankruptcy Law.

Section 6.03. Waiver.

Each Guarantor waives and agrees not to assert: (a) any right to require the Holders or the 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 the 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

-18-

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 such 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 such 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, any Guarantor receives any payment from the Company, such payment shall be held in trust by such Guarantor for the benefit of the Holders, and shall be segregated from the other funds of such Guarantor, and shall forthwith 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.

-19-

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 the Guarantors 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, 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.

-20-

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 such 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 such 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 Subsidiaries that are not Guarantors, directly or indirectly, to guarantee any Specified Indebtedness (“Guaranteed 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 such Guaranteed Indebtedness is guaranteed, the Guaranteed Obligations. 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. 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 right of payment to, the Guarantee of such Subsidiary or (2) is subordinated by its terms in right of payment to the Notes, then the guarantee of such Guaranteed

-21-

Indebtedness shall be subordinated to the Guarantee of such 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’s 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 all Specified Indebtedness (other than by reason of payment under its guarantee of 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, the Guarantors under this Supplemental Indenture will be released from their Guarantees.

M.D.C. HOLDINGS, INC.

2.500% Senior Notes due 2031

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 semi-annually on January 15 and July 15 of each year, commencing on July 15, 2021, 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 January 11, 2021; 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 January 1 and July 1 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 January 11, 2021 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

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., ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, 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. If the Notes are redeemed prior to July 15, 2030 (the “Par Call Date”), the Redemption Price for the Notes to be redeemed will equal 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 semi-annual basis, at the Treasury Rate plus 25 basis points (0.25%), plus, in each case, accrued and unpaid interest, if any, on such Notes to the Redemption Date. If the Notes are redeemed on or after the Par Call Date, the Redemption Price for the Notes to be redeemed will equal 100% of the principal amount of such Notes, plus accrued and unpaid interest, if any, on such 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. Interest Rate Adjustment.

If a Change of Control occurs and within 60 days thereafter all three of the Ratings Agencies have less than Investment Grade debt ratings assigned to the Notes, whether as a result of a downgrade or otherwise, the per annum interest rate on the Notes will increase from the interest rate payable on the Notes immediately before the Change of Control. The interest rate will increase by 0.25% for each rating level below Investment Grade by each of the two Rating Agencies with the lowest ratings (i.e., if two Rating Agencies are two levels below Investment Grade and the third Rating Agency is one level below Investment Grade, the interest rate increase will be 1.00% per annum). In the event that only two Rating Agencies have debt ratings assigned to the Notes, those two debt ratings will be used to determine any interest rate increase. In the event that only one Rating Agency has a debt rating assigned to the Notes, the interest rate increase will be two times 0.25% for each rating level below Investment Grade by the Rating Agency that has a debt rating assigned to the Notes. In the event that no Rating Agency has a debt rating assigned to the Notes, the interest rate increase will be 2.00% per annum. Any downgrade of the ratings assigned to the Notes that occurs outside of the 60 day period will not alter the per annum interest rate.

In no event shall: (1) the total increase in the interest rate on the Notes exceed 2.00% per annum above the interest rate payable on the Notes on the date of their initial issuance; or (2) the interest rate increase unless the debt ratings on the Notes by all Rating Agencies that have debt ratings assigned to the Notes are below Investment Grade within 60 days after the Change of Control.

If at any time after the interest rate on the Notes has been adjusted upward pursuant to this provision as a result of a Rating Agency rating the Notes below Investment Grade, that Rating Agency (or a replacement rating agency selected by us under the circumstance set forth in, and in accordance with, the definition of “Rating Agency”) thereafter increases its rating with respect to the Notes, the per annum interest rate on the Notes will decrease by 0.25% per annum (or, if the debt rating for only one Rating Agency was used to determine the interest rate increase pursuant to the fourth sentence of this Paragraph 6, two times 0.25% per annum) for each level of improvement in the rating of the Notes by such Rating Agency; provided that the decrease in interest rate resulting therefrom will not exceed the aggregate percentage increase in the interest rate that resulted from the prior lower rating by such Rating Agency. In no event will the interest rate on the Notes ever be less than the interest rate payable on the Notes on the date of their initial issuance.

Any interest rate change described above will take effect as of the first day of the interest period for which the next interest payment will be made.

The interest rate on the Notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any Rating Agency) if all of the Rating Agencies subsequently increase their rating of the Notes to the following levels at the same time (▇▇▇▇▇’▇: A3; S&P: A-; Fitch: A-; or the equivalent if with respect to any substitute rating agency) or higher.
