Exhibit 4.2

                                   "EXHIBIT "A"

                                     GUARANTY


TO:      BANK ONE, NA, a national banking  association,  as Administrative Agent
         for the Banks  that are  parties to the  Amended  and  Restated  Credit
         Agreement  dated as of October  8, 1999 (as  amended,  supplemented  or
         otherwise  modified from time to time, the "Credit  Agreement"),  among
         M.D.C.   HOLDINGS,   INC.,   a   Delaware   corporation,   Banks,   and
         Administrative Agent, and to the Banks. Capitalized terms not otherwise
         defined  herein  shall  have  the  meaning  set  forth  in  the  Credit
         Agreement.


       FOR  VALUABLE   CONSIDERATION,   the  undersigned   (hereinafter   called
"Guarantor"),  whose  address is set forth after  Guarantor's  signature  below,
unconditionally  guarantees and promises to pay to Administrative Agent, for the
benefit of Banks and their  respective  successors,  endorsees,  transferees and
assigns,  or order, within one (1) business day after demand, in lawful money of
the United  States,  (i) the Notes,  principal  and  interest and all other sums
payable thereunder,  or at the election of Administrative  Agent any one or more
installments thereof, in the event that Borrower fails to punctually pay any one
or more installments of the Note (principal  and/or interest),  or any other sum
payable thereunder at the time and in the manner provided therein;  and (ii) all
other  indebtedness of Borrower to  Administrative  Agent or to any Bank arising
under  or in  connection  with  the  Notes,  the  Credit  Agreement  or any Loan
Documents  (the  indebtedness  evidenced  by the Notes  together  with all other
indebtedness   specified   above  is   hereinafter   collectively   called   the
"Indebtedness").

       1.  The  obligations  of  Guarantor  hereunder  are  separate  and
independent  of the  obligations of Borrower and of any other  guarantor,  and a
separate  action or actions  may be brought  and  prosecuted  against  Guarantor
whether  action is brought  against  Borrower or any other  guarantor or whether
Borrower  or any  other  guarantor  is  joined in any  action  or  actions.  The
obligations of Guarantor  hereunder shall survive and continue in full force and
effect  until  payment  in full of the  Indebtedness  is  actually  received  by
Administrative Agent for the benefit of Banks and the period of time has expired
during which any payment  made by any  Borrower or  Guarantor to  Administrative
Agent for the benefit of Banks may be  determined to be a  Preferential  Payment
(defined below), notwithstanding any release or termination of Borrower's or any
other guarantor's  liability by express or implied agreement with Administrative
Agent  or  any  Bank  or by  operation  of  law  and  notwithstanding  that  the
Indebtedness  or any part thereof is deemed to have been paid or  discharged  by
operation of law or by some act or agreement of  Administrative  Agent or Banks.
For purposes of this Guaranty,  the Indebtedness shall be deemed to be paid only
to the extent that Administrative  Agent, on behalf of Banks,  actually receives
immediately available funds.


       2.  Guarantor agrees that to the extent Borrower or Guarantor makes
any  payment  to   Administrative   Agent  or  Banks  in  connection   with  the
Indebtedness,  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
Administrative  Agent or Banks 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 Guaranty shall
continue to be effective or shall be reinstated, as the case may be, and, to the
extent of such  payment  or  repayment  by  Administrative  Agent or Banks,  the
Indebtedness  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.

       3.  Guarantor  is  providing  this  Guaranty at the  instance  and
request  of  Borrower  to  induce  Administrative  Agent  and Banks to extend or
continue financial  accommodations to Borrower.  Guarantor hereby represents and
warrants  that  Guarantor is and will  continue to be fully  informed  about all
aspects  of the  financial  condition  and  business  affairs of  Borrower  that
Guarantor  deems relevant to the  obligations of Guarantor  hereunder and hereby
waives and fully discharges  Administrative Agent and each Bank from any and all
obligations  to communicate to Guarantor any  information  whatsoever  regarding
Borrower  or  Borrower's  financial  condition  or business  affairs.  Guarantor
acknowledges that Borrower owns,  directly or indirectly,  all of the issued and
outstanding  shares of stock of each Guarantor,  that Guarantor and Borrower are
engaged in related businesses, and that Guarantor will derive substantial direct
and  indirect  benefit from the  extension  of credit by Banks  evidenced by the
Indebtedness.

       4.  Guarantor  authorizes  Administrative  Agent and Banks, without
notice or demand and without affecting  Guarantor's  liability  hereunder,  from
time to time, to: (a) renew, modify, compromise, extend, accelerate or otherwise
change  the  time  for  payment  of,  or  otherwise  change  the  terms  of  the
Indebtedness or any part thereof, including increasing or decreasing the rate of
interest thereon; (b) release,  substitute or add any one or more endorsers,  or
other guarantors; (c) take and hold security for the payment of this Guaranty or
the  Indebtedness,  and enforce,  exchange,  substitute,  subordinate,  waive or
release any such  security;  (d) proceed  against  such  security and direct the
order  or  manner  of sale of  such  security  as  Administrative  Agent  in its
discretion  may  determine;  and (e) apply any and all payments  from  Borrower,
Guarantor or any other  guarantor,  or recoveries  from such  security,  in such
order or manner as Administrative Agent in its discretion may determine.

       5.  Guarantor  waives and  agrees not to assert:  (a) any right to
require  Administrative  Agent or Banks to proceed against Borrower or any other
guarantor,  to proceed against or exhaust any security for the Indebtedness,  to
pursue any other  remedy  available  to  Administrative  Agent and Banks,  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 Guaranty; (d) notice of the existence,  creation or incurring
of new or additional  indebtedness  of Borrower to  Administrative

                                      -2-

Agent or any Bank;  and (e) any defense  arising by reason of any  disability or
other  defense  of  Borrower  or by  reason  of the  cessation  from  any  cause
whatsoever  (other than  payment in full of all  amounts  demanded to be paid by
Guarantor   under  this   Guaranty)  of  the   liability  of  Borrower  for  the
Indebtedness.   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  Guarantor's  obligations  hereunder.   Until  payment  in  full  of  the
Indebtedness, Guarantor shall have no right of subrogation and hereby waives any
right to enforce any remedy which  Administrative  Agent and Banks now have,  or
may hereafter have,  against Borrower,  and waives any benefit of, and any right
to participate in, any security now or hereafter held by Administrative Agent on
behalf of Banks.

       6.  If from  time to  time  Borrower  shall  have  liabilities  or
obligations to Guarantor,  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  Obligations.  Guarantor
agrees that such  liabilities and obligations of Borrower 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 such Borrower. Guarantor and, by
their acceptance of this Guaranty, Administrative Agent and each Bank agree 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 Borrower
and  accepted by  Guarantor  as such  payments  become  due;  and (ii) after the
occurrence and during the  continuation  of an Event of Default,  Borrower 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  Borrower,  such payment
shall be held in trust by Guarantor for the benefit of Administrative  Agent and
Banks,  shall  be  segregated  from the  other  funds of  Guarantor,  and  shall
forthwith be paid by Guarantor to Administrative  Agent for the benefit of Banks
and applied to payment of the Obligations whether or not then due.

                  (a)  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
         Borrower,  or the proceeds thereof, to creditors of Borrower, by reason
         of the  liquidation,  dissolution,  or other  winding up of  Borrower's
         business, or in the event of any receivership, insolvency or bankruptcy
         proceedings  by or against  Borrower,  or assignment for the benefit of
         creditors,  or of any proceedings by or against Borrower 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  Borrower 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

                                          -3-


         in cash or other property, which shall be made or shall be payable with
         respect to any Subordinated Indebtedness shall be paid over to
         Administrative Agent on behalf of Banks for application to the payment
         of the Obligations, whether due or not due, and no payments  shall  be
         made upon or in respect of the Subordinated Indebtedness unless and
         until the Obligations  shall have been paid and satisfied in full. In
         any such event, all claims of  Administrative  Agent and Banks and all
         claims of  Guarantor  shall,  at the  option of  Administrative
         Agent and Banks,  forthwith  become due and payable  without  demand or
         notice.

                  (b)  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
         Borrower,  or the proceeds thereof, to creditors of Borrower, by reason
         of the  liquidation,  dissolution,  or other  winding up of  Borrower's
         business, or in the event of any receivership, insolvency or bankruptcy
         proceedings  by or against  Borrower,  or assignment for the benefit of
         creditors,  or of any proceedings by or against Borrower 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  Borrower for
         the  purpose of  receiving  payment  thereof,  or on  account  thereof,
         Guarantor irrevocably authorizes and empowers  Administrative Agent, or
         any person  Administrative Agent 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
         Borrower on account of the Subordinated  Indebtedness as Administrative
         Agent,  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  Banks  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  Obligations,  and Guarantor  hereby agrees,  from time to time and
         upon request, to make, execute and deliver to Administrative Agent such
         powers  of  attorney,  assignments,   endorsements,  proofs  of  claim,
         pleadings,  verifications,  affidavits,  consents,  agreements or other
         instruments  as may be  requested by  Administrative  Agent in order to
         enable  Administrative  Agent and Banks 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.

                  (c) Except as otherwise  permitted herein,  should any payment
         or  distribution  or  security  or  proceeds  thereof  be  received  by
         Guarantor upon or with respect to the Subordinated  Indebtedness  prior
         to  the  satisfaction  of the  Obligations,  Guarantor  will  forthwith
         deliver  the  same to  Administrative  Agent  on  behalf  of  Banks  in
         precisely the form as received except for the endorsement or assignment

                                          -4-


         of  Guarantor  where  necessary  for  application  on the  Obligations,
         whether due or not due, and until so  delivered  the same shall be held
         in trust by Guarantor as property of Administrative  Agent on behalf of
         Banks.  In the  event  of the  failure  of  Guarantor  to make any such
         endorsement or assignment, Administrative Agent, or any of its officers
         or employees,  on behalf of Administrative Agent, is hereby irrevocably
         authorized to make the same.

                  (d)  Guarantor  agrees to maintain  in its  records  notations
         satisfactory  to  Administrative  Agent of the rights and priorities of
         Administrative  Agent and Banks hereunder,  and from time to time, upon
         request, to furnish  Administrative Agent for the benefit of Banks with
         sworn financial statements.  Banks and Administrative Agent may inspect
         the books of account  and any records of  Guarantor  at any time during
         business  hours.  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
         Guaranty.

       7.  It is not  necessary  for  Administrative  Agent or any Bank to
inquire  into the  powers  of  Borrower  or the  officers,  directors,  members,
managers,  partners,  trustees or Administrative  Agents acting or purporting to
act on its behalf,  and any of the Indebtedness made or created in reliance upon
the professed exercise of such powers shall be guaranteed hereunder.

       8.  Guarantor agrees to deliver to  Administrative  Agent and Banks
financial  statements and other financial  information  relating to Guarantor in
form and level of detail, and containing certifications, as required pursuant to
Section  7.1 of the Credit  Agreement.  Guarantor  further  agrees to comply all
covenants,  representations  and warranties in the Credit Agreement  relating to
Guarantor.

       9.  Guarantor agrees to pay all attorneys' fees and all other costs
and  expenses  which  may be  incurred  by  Administrative  Agent or any Bank in
enforcing this Guaranty.

      10.  This  Guaranty  sets forth the entire  agreement of Guarantor,
Administrative  Agent and Banks with  respect to the subject  matter  hereof and
supersedes  all  prior  oral  and  written  agreements  and  representations  by
Administrative Agent or any Bank to Guarantor.  No modification or waiver of any
provision  of this  Guaranty  or any right of  Administrative  Agent or any Bank
hereunder and no release of Guarantor  from any  obligation  hereunder  shall be
effective   unless  in  a  writing   executed  by  an   authorized   officer  of
Administrative Agent and each Bank. There are no conditions,  oral or otherwise,
on the effectiveness of this Guaranty.

      11.  This  Guaranty  shall inure to the benefit of  Administrative
Agent and each Bank and their  respective  successors  and  assigns and shall be
binding upon Guarantor and its heirs, personal  representatives,  successors and
assigns. Administrative Agent and each Bank may assign this Guaranty in whole or
in part without notice.

                                      -5-

      12.  THIS  GUARANTY  SHALL BE  CONSTRUED  IN  ACCORDANCE  WITH THE
INTERNAL  LAWS  (AND NOT THE LAW OF  CONFLICTS)  OF THE STATE OF  ILLINOIS,  BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

      13.  Subject  to the  provisions  of this  Section  13,  Guarantor
agrees,  and Banks and  Administrative  Agent by accepting this Guaranty  agree,
that they shall submit to binding  arbitration any and all claims,  disputes and
controversies between or among them (and their respective  employees,  officers,
directors, attorneys, and other agents if permitted by law or a contract between
them and such persons)  relating to this Guaranty and the Loan Documents and the
negotiation,   execution,    collateralization,    administration,    repayment,
modification,  extension  or  collection  thereof  or arising  thereunder.  Such
arbitration  shall proceed in Chicago,  Illinois,  shall be governed by Illinois
law and shall be conducted in accordance with the Commercial  Arbitration  Rules
of the  American  Arbitration  Association  (the  "AAA")  as  modified  in  this
Paragraph 13.  Judgment  upon the award  rendered by each  arbitrator(s)  may be
entered in any court having jurisdiction.

                  (a) Nothing in the  preceding  paragraph,  nor the exercise of
         any right to arbitrate  thereunder,  shall limit the right of any party
         hereto  (1)  subject to  provisions  of  applicable  law,  to  exercise
         self-help  remedies such as setoff or  repossession  or other self-help
         remedies  provided in the Credit  Agreement or any other Loan Document;
         or (2) to obtain  provisional  or ancillary  remedies such as replevin,
         injunctive  relief,  attachment,  or  appointment  of a receiver from a
         court having jurisdiction,  before, during or after the pendency of any
         arbitration proceeding,  or (3) to defend or obtain injunctive or other
         equitable   relief   against   the   foregoing   or  assert   mandatory
         counterclaims,   if  any,  prior  to  and  during  the  pendency  of  a
         determination in arbitration of issues of performance, default, damages
         and other such claims and disputes.

                  (b) Arbitration hereunder shall be before a three-person panel
         of  neutral  arbitrators,  consisting  of one  person  from each of the
         following categories:  (1) an attorney who has practiced in the area of
         commercial  real estate law for at least ten (10)  years;  (2) a person
         with at least ten (10) years'  experience in real estate  lending;  and
         (3)  a  person  with  at  least  ten  (10)  years'  experience  in  the
         homebuilding  industry.  The AAA shall submit a list of persons meeting
         the criteria  outlined above for each category of  arbitrator,  and the
         parties  shall  select  one  person  from each  category  in the manner
         established by the AAA.

                  (c) In any dispute  between the parties  that is  arbitratable
         hereunder,  where the  aggregate of all claims and the aggregate of all
         counterclaims  is an amount  less than  Fifty  Thousand  and  No/100ths
         Dollars ($50,000.00),  the arbitration shall be before a single neutral
         arbitrator to be selected in accordance  with the  Commercial  Rules of
         the  American  Arbitration  Association  and  shall  proceed  under the
         Expedited Procedures of said Rules.

                                           -6-

                  (d) In any arbitration hereunder, the arbitrators shall decide
         (by documents only or with a hearing,  at the arbitrators'  discretion)
         any pre-hearing motions which are substantially  similar to pre-hearing
         motions to dismiss  for failure to state a claim or motions for summary
         adjudication.

                  (e) In any arbitration hereunder, discovery shall be permitted
         in accordance with the Illinois Code of Civil Procedure.  Scheduling of
         such discovery may be determined by the arbitrators,  and any discovery
         disputes shall be finally determined by the arbitrators.

                  (f) The Illinois rules of evidence shall control the admission
         of  evidence  at the hearing in any  arbitration  conducted  hereunder,
         provided,  however,  no error by the  arbitrators in application of the
         Rules  of  Evidence  shall  be  grounds,  as  such,  for  vacating  the
         arbitrators' award.

                  (g)  Notwithstanding  any  AAA  rule  to  the  contrary,   the
         arbitration award shall be in writing and shall specify the factual and
         legal basis for the award,  including  findings of fact and conclusions
         of law.

                  (h) Each party shall each bear its own costs and  expenses and
         an equal share of the  arbitrators'  costs and  administrative  fees of
         arbitration.

      14.  GUARANTOR,  AND  BANKS BY  ACCEPTING  THIS  GUARANTY,  HEREBY
IRREVOCABLY  SUBMIT  TO THE  NON-EXCLUSIVE  JURISDICTION  OF ANY  UNITED  STATES
FEDERAL OR ILLINOIS  STATE COURT  SITTING IN CHICAGO,  ILLINOIS IN ANY ACTION OR
PROCEEDING  ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND GUARANTOR,  AND
BANKS BY ACCEPTING THIS GUARANTY,  HEREBY  IRREVOCABLY  AGREE THAT ALL CLAIMS IN
RESPECT OF SUCH ACTION OR  PROCEEDING  MAY BE HEARD AND  DETERMINED  IN ANY SUCH
COURT AND IRREVOCABLY WAIVE ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE
VENUE OF ANY SUCH  SUIT,  ACTION OR  PROCEEDING  BROUGHT IN SUCH A COURT OR THAT
SUCH COURT IS AN  INCONVENIENT  FORUM.  NOTHING IN THIS PARAGRAPH 15 SHALL LIMIT
THE  RIGHT  OF  ADMINISTRATIVE  AGENT  OR ANY  BANK OR  ISSUING  BANK  TO  BRING
PROCEEDINGS AGAINST GUARANTOR IN THE COURTS OF ANY OTHER  JURISDICTION.  SUBJECT
TO THE  PROVISIONS  OF  SECTION  14,  UNLESS  PROHIBITED  BY LAW,  ANY  JUDICIAL
PROCEEDING BY GUARANTOR AGAINST ADMINISTRATIVE AGENT OR ANY BANK OR ISSUING BANK
OR ANY AFFILIATE OF ADMINISTRATIVE  AGENT OR ANY BANK OR ISSUING BANK INVOLVING,
DIRECTLY OR  INDIRECTLY,  ANY MATTER IN ANY WAY  ARISING OUT OF,  RELATED TO, OR
CONNECTED  WITH THIS GUARANTY OR ANY OTHER LOAN  DOCUMENT  SHALL BE BROUGHT IN A
COURT IN CHICAGO, ILLINOIS.

                                        -7-


      15.  SUBJECT TO THE  PROVISIONS  OF SECTION 14,  GUARANTOR  HEREBY
WAIVES  TRIAL  BY  JURY  IN  ANY  JUDICIAL  PROCEEDING  INVOLVING,  DIRECTLY  OR
INDIRECTLY,  ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY
WAY ARISING OUT OF, RELATED TO, OR CONNECTED  WITH THE GUARANTY,  ANY OTHER LOAN
DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

      16.  Guarantor acknowledges that the rights and responsibilities of
Administrative  Agent under this  Guaranty  with  respect to any action taken by
Administrative  Agent or the exercise or non-exercise by Administrative Agent of
any option,  right,  request,  judgment or other  right or remedy  provided  for
herein  or  resulting  or  arising  out  of  this  Guaranty  shall,  as  between
Administrative  Agent and Banks, be governed by the Credit Agreement and by such
other agreements with respect thereto as may exist from time to time among them,
but, as between  Administrative Agent and Guarantor,  Administrative Agent shall
be  conclusively  presumed  to be acting as agent for Banks  with full and valid
authority so to act or refrain from acting, and Guarantor shall not be under any
