REGISTRATION RIGHTS AGREEMENT


                  THIS  REGISTRATION  RIGHTS  AGREEMENT (the "Agreement"), dated
December  31,  1996,  is  made  by and  between  Homeplex  Mortgage  Investments
Corporation,  a Maryland  corporation (the "Company"), and Steven J. Hilton (the
"Holder").

                  The Company and the Holder agree as follows:

                  1.  Shares.  As used herein,  the term "Shares" shall mean the
shares of common stock,  $.01 par value, of the Company,  acquired by the Holder
pursuant to that  certain  Agreement  and Plan of  Reorganization  (the  "Merger
Agreement") among the Company,  Monterey Homes  Construction II, Inc.;  Monterey
Homes Arizona II, Inc. and the Monterey  Shareholders (as defined therein) dated
September 13, 1996  (including  the  Contingent  Stock (as defined in the Merger
Agreement) and underlying that certain Stock Option Agreement by and between the
Company and the Holder dated  December  31, 1996 (the  "Option  Shares") and any
securities  issued to Holder as a dividend or  distribution  in respect of or in
exchange  for such shares,  whether by  reclassification,  stock split,  reverse
stock split or otherwise) until their sale under this Agreement or in accordance
with Rule 144 (or any similar  provision then in force) under the Securities Act
of 1933, as amended (the "Securities Act").

                  2.  Demand  Registration.  (a)  Subject to the  provisions  of
Section 2(b) hereof,  the Holder may at any time after the first  anniversary of
the date of this  Agreement  
                                       1

make up to two written requests to the Company for  registration  under Form S-3
(or such other  appropriate  or successor form if Form S-3 is not available) and
in accordance with the provisions of Rule 415  promulgated  under the Securities
Act of all or a portion of his Shares.  The Company  shall prepare and file with
the Securities and Exchange  Commission (the "SEC") a registration  statement on
Form  S-3 (or  such  other  appropriate  or  successor  form if Form  S-3 is not
available)  under the  Securities  Act covering such Shares,  shall use its best
efforts to cause such  registration  statement to become effective within ninety
(90) days of the Holder's request and shall file such post-effective  amendments
to such registration statement in order for it to remain effective without lapse
until  the  sale of all  the  Shares  and  shall  qualify  such  offering  under
applicable blue sky or state securities laws.

                           (b)  Notwithstanding  delivery of any written request
referred to in Section  2(a),  the Company will have the prior right at any time
to conduct public  offerings of its common stock for its corporate  purposes and
may preempt any pending demand registration,  in which case Section 3 will apply
to the offering. Under these circumstances, the Company will not be obligated to
effect  the  requested  demand  registration  under  this  Section  2  and  such
previously requested  registration will not count as a demand registration under
Section 2(a). In addition,  if, prior to the time a written request is delivered
under Section 2(a),  the Company has given  written  notice  pursuant to Section
3(a) of its intention to file a registration statement, the Company shall not be
obligated to cause the requested  demand  registration to become effective until
120 days after the effective  date of such  
                                       2

registration  statement  or until the Company  ceases to  diligently  pursue the
preparation, filing and effectiveness of such registration statement.

                           (c) The Company shall file a  registration  statement
on Form S-8 with respect to the Option Shares promptly after the date hereof and
shall  use its best  efforts  to cause  such  registration  statement  to remain
effective until the related stock options have been exercised or expired.

                           (d) The Company  shall pay the expenses  described in
Section 6 for the registration pursuant to this Section 2.

                  3.  Incidental  Registration  Rights.  (a) If at any  time the
Company  shall  determine  to  proceed  with the  preparation  and  filling of a
registration  statement under the Securities Act in connection with the proposed
offer and sale of any of its  securities  by it or any of its  security  holders
(other than a registration  statement on Form S-4, S-8 or other limited  purpose
form), the Company will give written notice of its  determination to the Holder.
Upon the written request from the Holder,  within ten (10) days after receipt of
any such notice from the Company, the Company will, subject to the provisions of
Section 3(b),  include all Shares  requested by the Holder in such  registration
statement  (and any  related  qualification  under blue sky or state  securities
laws); provided, however, that nothing herein shall prevent the Company from, at
any time,  abandoning or delaying any registration  under this Section 3. If any
registration  pursuant to this  Section 3 shall be  underwritten  in whole or in
part, the Company shall require that the Shares requested for inclusion pursuant
to this  
                                       3

Section 3 be  included  in the  underwriting  on the same terms and  conditions,
including lock-up provisions, as the securities otherwise being sold through the
underwriters.

                           (b)  Notwithstanding  the foregoing,  if the managing
underwriter  determines and advises that the inclusion of the Shares proposed to
be included in the underwritten public offering,  together with any other issued
and  outstanding  securities  proposed  to be  included  therein  by  holders of
securities  other than the Holder who have  registration  rights  which are pari
passu to the Holder,  would  interfere  with the  successful  marketing  of such
securities,  then  the  number  of such  Shares  that the  managing  underwriter
believes may be sold in such underwritten public offering shall be allocated for
inclusion in the registration  statement in the following order of priority: (i)
first,  the  securities  being offered by the Company,  and (ii)  secondly,  the
number  of  Shares  then  owned by the  Holder  and other  holders  entitled  to
participate  therein who have  registration  rights  which are pari passu to the
Holder on a pro rata basis or such other basis as they shall have agreed.

                           (c) The Company  shall pay the expenses  described in
Section 6 for registration statements filed pursuant to this Section 3.

                  4.  Registration  Procedures.  If and  whenever the Company is
required  by the  provisions  of  Section 2 or 3 to effect the  registration  of
Shares under the Securities Act, the Company will:

                           (a)  prepare  and file  with  the SEC a  registration
statement  with  respect to such  securities,  and use its best efforts to cause
such  registration  statement to 
                                       4

become and remain  effective for such period as may be  reasonably  necessary to
effect the sale of such securities (the "Effective Period").

                           (b) prepare and file with the SEC such  amendments to
such registration  statement and supplements to the prospectus contained therein
as may be  necessary  to keep  such  registration  statement  effective  for the
Effective  Period as may be  reasonably  necessary  to  effect  the sale of such
securities.

                           (c) furnish to the Holder and to the underwriters for
the  securities  being  registered,  such  reasonable  number  of  copies of the
registration statement,  preliminary prospectus, final prospectus and such other
documents as the Holder and such underwriters may reasonably request in order to
facilitate the public offering of such securities.

                           (d) use its best  efforts to  register or qualify the
Shares covered by such  registration  statement  under such state  securities or
blue sky laws of such  jurisdictions  as the  Holder may  reasonably  request in
writing within ten (10) days following the original filing of such  registration
statement,  except  that the  Company  shall not for any  purpose be required to
execute a general  consent to service of process or to qualify to do business as
a foreign  corporation  in any  jurisdiction  wherein it is not so  qualified or
subject  itself to taxation in a jurisdiction  where it had not previously  been
subject to taxation,  or take any other action that would subject the Company to
service of process in a lawsuit  other than one arising out of the  registration
of the Shares.

                           (e)  notify  the  Holder,  promptly  after  it  shall
receive notice thereof, 
                                       5

of  the  time  when  such  registration  statement  has  become  effective  or a
supplement to any prospectus  forming a part of such registration  statement has
been filed.

                           (f) notify the Holder  promptly of any request by the
SEC  for  the  amending  or  supplementing  of such  registration  statement  or
prospectus or for additional information.

                           (g)  prepare  and  promptly  file  with  the  SEC and
promptly notify the Holder of the filing of such amendment or supplement to such
registration  statement  or  prospectus  as  may be  necessary  to  correct  any
statements  or  omissions  if, at any time when a  prospectus  relating  to such
securities is required to be delivered under the Securities Act, any event shall
have occurred as the result of which any such prospectus or any other prospectus
as then in effect would  include an untrue  statement of a material fact or omit
to state any material  fact  necessary to make the  statements  therein,  in the
light of the circumstances in which they were made, not misleading; and

                           (h)  advise  the  Holder,  promptly  after  it  shall
receive notice or obtain knowledge thereof, of the issuance of any stop order by
the SEC  suspending  the  effectiveness  of such  registration  statement or the
initiation or  threatening  of any  proceeding for that purpose and promptly use
its best  efforts to  prevent  the  issuance  of any stop order or to obtain its
withdrawal if such stop order should be issued.

                  5.   Underwriting.   The   Holder   agrees   that  any  demand
registration  involving the issuance of Common Stock by the Company will, at the
Company's option, 
                                       6

be effected pursuant to an underwritten public offering.  The Holder will select
the book-running  managing underwriter and any additional investment bankers and
managers to be used in connection  with the demand  registration,  provided that
such underwriter and additional  investment  bankers and managers are reasonably
acceptable to the Company and that the underwriting  discounts,  fees, discounts
and any other compensation proposed to be charged by such persons is competitive
with that obtainable from other underwriters, bankers and managers of comparable
quality  and  reputation.  The  Holder  may  not  participate  in an  incidental
registration  hereunder  unless such Holder (a) agrees to sell the Shares on the
basis provided in the underwriting  arrangements,  if any, and (b) completes and
executes  all  questionnaires,  powers of  attorney,  indemnities,  underwriting
agreements  and  other  documents  reasonably  required  under the terms of such
underwriting arrangements, if any, and these registration rights.

                  6. Expenses.  (a) With respect to any  registration  requested
pursuant to Section 2 hereof,  and with  respect to an  inclusion of Shares in a
registration  statement  pursuant  to  Section 3  hereof,  all  fees,  costs and
expenses  of such  registration,  inclusion  and  public  offering  (as  further
specified  in  paragraph  (b) below)  shall be borne by the  Company;  provided,
however,  that the Holder shall bear the underwriting  discounts and commissions
and transfer taxes in respect of the sale of his Shares.

                           (b) The fees,  costs and expenses of  registration to
be borne by the Company as provided in Section 6(a) above shall include, without
limitation, all registration, 
                                       7

filing,  and NASD  fees,  printing  expenses,  fees and  disbursements  of legal
counsel and accountants for the Company and all legal fees and disbursements and
other  expenses  of  complying  with  state  securities  or blue sky laws of any
jurisdictions  in which the  securities to be offered are to be  registered  and
qualified.

                  7.  Indemnification.  (a) The Company will  indemnify and hold
harmless the Holder and any  underwriter  (as defined in the Securities Act) for
the Holder and each  person,  if any, who  controls  such Holder or  underwriter
within the meaning of the  Securities  Act, from and against and will  reimburse
the Holder and each such underwriter and controlling person with respect to, any
and all loss,  damage,  liability,  cost and  expense to which the Holder or any
such  underwriter or controlling  person may become subject under the Securities
Act or  otherwise,  insofar  as such  losses,  damages,  liabilities,  costs  or
expenses are caused by any untrue  statement or alleged untrue  statement of any
material fact contained in such registration statement, any prospectus contained
therein or any  amendment or  supplement  thereto,  or arise out of or are based
upon the omission or alleged  omission to state therein a material fact required
to be stated  therein or necessary to make the statements  therein,  in light of
the  circumstances in which they were made, not misleading;  provided,  however,
that the Company will not be liable in any such case to the extent that any such
loss,  damage,  liability,  cost or  expenses  arises out of or is based upon an
untrue  statement or alleged untrue statement or omission or alleged omission so
made in conformity  with  information  furnished in writing by the Holder,  such
underwriter or such controlling  person  
                                       8

specifically for use in the preparation thereof. The Company will not be subject
to any  liability  for any  settlement  made without its consent,  which consent
shall not be unreasonably withheld.

                           (b) The Holder will  indemnify  and hold harmless the
Company, its directors and officers,  any controlling person and any underwriter
thereof from and against,  and will  reimburse  the Company,  its  directors and
officers,  any controlling  person and any underwriter  thereof with respect to,
any and all loss, damage, liability, cost or expense to which the Company or any
controlling  person and/or any underwriter  thereof may become subject under the
Securities Act or otherwise, insofar as such losses, damages,  liabilities, cost
or expenses are caused by any untrue  statement or alleged  untrue  statement of
any material  fact  contained in such  registration  statement,  any  prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the  omission or alleged  omission to state  therein a material  fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances in which they were made, not misleading, in each case
to the extent,  but only to the extent,  that such untrue  statement  or alleged
untrue  statement or omission or alleged  omission was so made in reliance  upon
and in conformity with  information  furnished in writing by or on behalf of the
Holder specifically for use in the preparation  thereof.  The Holder will not be
subject to any  liability  for any  settlement  made without its consent,  which
consent shall not be unreasonably withheld.
                                       9

                           (c) Promptly  after receipt by an  indemnified  party
pursuant to the  provisions  of paragraph (a) or (b) of this Section 6 of notice
of the  commencement of any action involving the subject matter of the foregoing
indemnity  provisions such  indemnified  party will, if a claim thereof is to be
made against the indemnifying party pursuant to the provisions of said paragraph
(a) or (b), promptly notify the indemnifying party of the commencement  thereof;
but the  omission to so notify the  indemnifying  party will not relieve it from
any  liability  which  it may  have  to any  indemnified  party  otherwise  than
hereunder,  except to the extent that such  omission  materially  and  adversely
affects the  indemnifying  party's  ability to defend against or compromise such
claim.  In case such  action is brought  against  any  indemnified  party and it
notifies the indemnifying  party of the commencement  thereof,  the indemnifying
party  shall have the right to  participate  in,  and, to the extent that it may
wish, jointly with any other indemnifying  party similarly  notified,  to assume
the defense  thereof,  with  counsel  satisfactory  to such  indemnified  party;
provided,  however,  that if the  defendants  in any  action  include  both  the
indemnified  party and the  indemnifying  party  and  there  are legal  defenses
available to the indemnified  party and/or other  indemnified  parties which are
different from or in addition to those available to the  indemnifying  party, or
if  there  is a  conflict  of  interest  which  would  prevent  counsel  for the
indemnifying party from also representing the indemnified party, the indemnified
party or parties shall have the right to select separate  counsel to participate
in the  defense of such action on behalf of such  indemnified  party or parties.
After notice from the indemnifying party to an indemnified party of its election
so to assume the defense thereof,  the indemnifying  party will not be liable to
such  indemnified  
                                       10

party  pursuant to the  provisions of said paragraph (a) or (b) for any legal or
other expense subsequently incurred by such indemnified party in connection with
the  defense  thereof  other  than  costs  of  investigation,   unless  (i)  the
indemnified  party shall have employed counsel in accordance with the provisions
of the preceding  sentence,  (ii) the indemnifying party shall not have employed
counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable  time after the notice of the  commencement of the action or
(iii) the  indemnifying  party has  authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party.

                           (d) If for any reason the  foregoing  indemnification
is unavailable,  or is insufficient to hold harmless an indemnified  party, then
the  indemnifying  party shall  contribute  to the amount paid or payable by the
indemnified party as a result of such losses,  claims,  damages,  liabilities or
expenses in such  proportion as is  appropriate to reflect the relative fault of
the indemnifying party on the one hand and the indemnified party on the other in
connection with the statement or omission which resulted in the losses,  claims,
damages,  liabilities  or  expenses,  as well as any  other  relevant  equitable
considerations.  No person guilty of fraudulent  misrepresentations  (within the
meaning  of   Section_11(f)   of  the  Securities  Act)  shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.

                  8. Miscellaneous.

                                       11

waived,  only by a written instrument executed by the Company and the Holder, in
the case of a waiver, by the party waiving compliance.  No delay by any party in
exercising  any right,  power or privilege  hereunder  shall operate as a waiver
thereof,  nor shall any waiver on the part of any party of any  right,  power or

privilege  hereunder,  preclude  any other or  further  exercise  thereof or the
exercise  of any other  right,  power or  privilege  hereunder.  The  rights and
remedies  herein  provided are cumulative and are not exclusive of any rights or
remedies that any party may otherwise have at law or in equity.

benefits of this  Agreement to any member of the Holder's  "immediate family" as
such term is defined in Rule 16a-1(e) or any trust,  partnership or other entity
created for the benefit of such persons or to any other  transferee of more than
150,000 shares prior to giving effect to the contemplated reverse stock split of
the Company as set forth in the Merger Agreement.

                           (f)  Counterparts.  This Agreement may be executed in
counterparts,  each of which shall be deemed an original  and all of which shall
constitute one and the same instrument.
