                  GUARANTEE AGREEMENT (this "Common Securities Guarantee"),
dated as of [         ], is executed and delivered by M.D.C. Holdings, Inc., a 
Delaware corporation (the "Guarantor"), for the benefit of the Holders (as 
defined herein) from time to time of the Common Securities (as defined herein) 
of MDC Capital Funding Trust [    ], a Delaware business trust (the "Issuer").

                  WHEREAS, pursuant to an amended and restated Declaration of

Issuer named therein, the Guarantor, as sponsor, and the holders from time to 
time of undivided beneficial interests in the assets of the Issuer, the Issuer 
is issuing on the date hereof     common securities having an aggregate 
liquidation amount of $     designated the Common Securities (the "Common 
Securities");

                  WHEREAS, as incentive for the Holders to purchase the Common
Securities, the Guarantor desires to irrevocably and unconditionally agree, to
the extent set forth in this Common Securities Guarantee, to pay to the Holders
of the Common Securities the Guarantee Payments (as defined herein) and to make
certain other payments on the terms and conditions set forth herein; and

                  WHEREAS, the Guarantor is also executing and delivering a
guarantee agreement (the "Capital Securities Guarantee") in substantially
identical terms to this Common Securities Guarantee for the benefit of the
holders of the Capital Securities (as defined herein), except that if an Event
of Default (as such term is defined in the Indenture) has occurred and is
continuing, the rights of Holders of the Common Securities to receive Guarantee
Payments under this Common Securities Guarantee are subordinated to the rights
of holders of Capital Securities to receive guarantee payments under the Capital
Securities Guarantee.

                  NOW, THEREFORE, in consideration of the purchase by each
Holder of Common Securities, which purchase the Guarantor hereby agrees shall

Securities;

                  (f) the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or



                                      -5-

PROVIDED, HOWEVER, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any rights
which it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Common
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Common Securities Guarantee. If any amount shall be paid
to the Guarantor in violation of the preceding sentence, the Guarantor agrees to
hold such amount in trust for the Holders and to pay over such amount to the
Holders.

SECTION 2.7 INDEPENDENT OBLIGATIONS

                  The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Common

the contrary contained in this Common Securities Guarantee, nothing shall
prevent the Guarantor from: (i) declaring or paying any dividend on, or making
any distribution with respect to, or redeeming, purchasing, acquiring or making
a liquidation payment with respect to, any of its capital stock in or with (x)
securities of the Guarantor (including capital stock) that rank junior to such
capital stock or (y) securities (including capital stock) of the Guarantor or
