                              AMENDED AND RESTATED
                           CHANGE OF CONTROL AGREEMENT
                             Effective July 1, 2003
                        (Original Date: February 1, 2000)

Dear ________:

      The Board of Directors believes that it is in the best interests of
Meritage Corporation ("Meritage"), and its shareholders to take appropriate
steps to allay any concerns you (sometimes referred to herein as "Executive")
may have about your future employment opportunities with Meritage and its
subsidiaries (Meritage and its subsidiaries are collectively referred to as the
"Company"). As a result, the Board has decided to offer to you the benefits
described below.

      1.    TERM OF AGREEMENT.

      This Agreement is effective immediately and will continue in effect as
long as you are employed by Meritage, unless you and Meritage agree in writing
to its termination.

      2.    SEVERANCE PAYMENT.

      If your employment with the Company is terminated without "Cause" (as
defined in Section 8) at any time within 90 days prior to or within two years
following a "Change of Control" (as defined in Section 6), you will receive the
"Severance Payment" described below. You will also receive the Severance Payment
if you terminate your employment for "Good Reason" (as defined in Section 7) at
any time within two years following a Change of Control.

      The Severance Payment equals the sum of (i) three times the higher of (x)
your annual base salary on the date of termination of your employment, or (y)
your annual base salary on the date preceding the Change of Control, and (ii)
three times the highest of the following: (x) your average incentive
compensation for the two years prior to termination of your employment, (y) your
incentive compensation for the year preceding the year in which the Change of
Control occurred, or (z) your "Minimum Incentive Compensation Amount" (as
defined below in Section 4).

      The Severance Payment will be paid in one lump sum as soon as
administratively feasible following termination of your employment, but in no
event more than 30 days following termination of your employment.

      You are not entitled to receive the Severance Payment if your employment
is terminated for Cause, if you terminate your employment without Good Reason,
or if your employment is terminated by reason of your "Disability" (as defined
in Section 10(d)) or your death (unless death or disability occurs after a
notice of termination). In addition, you are not entitled to receive the
Severance Payment if your employment is terminated by you or the Company for any
or no reason prior to 90 days before a Change of Control occurs or more than two
years after a Change of Control has occurred.
<PAGE>
      In order to receive the Severance Payment, you must execute any release
reasonably requested by the Company.

      The Severance Payment will be paid to you without regard to whether you
look for or obtain alternative employment following termination of your
employment with the Company.

      3.    BENEFITS CONTINUATION.

      If you are entitled to severance under Section 2, you will continue to
receive life, disability, accident and group health insurance benefits
substantially similar to those which you were receiving immediately prior to
termination of your employment for a period of 24 months following termination
of your employment. Such benefits shall be provided on substantially the same
terms and conditions as they were provided prior to the Change of Control,
provided that, if coverage for such benefits is not available under the plans of
the Company, the Company shall pay Executive an amount in cash equal to the cost
of your obtaining such alternative coverage.

      Benefits otherwise receivable pursuant to this Section also shall be
reduced or eliminated if and to the extent that you receive comparable benefits
from any other source (for example, another employer); provided, however, you
shall have no obligation to seek, solicit or accept employment from another
employer in order to receive such benefits.

      4.    INCENTIVE COMPENSATION.

      If you are employed by the Company on the day on which a Change of Control
occurs, the incentive compensation to which you will be entitled (pursuant to
any performance-based incentive compensation program established by the Company)
for the calendar year in which the Change of Control occurs will equal at least
the "Minimum Incentive Compensation Amount." The "Minimum Incentive Compensation
Amount" will equal the incentive compensation to which you would have been
entitled if the year were to end on the day on which the Change of Control
occurs, based upon performance up to that date. In measuring financial
performance, financial results through the date of the Change of Control will be
annualized.

      5.    STOCK OPTION ACCELERATION.

      Notwithstanding anything in this Agreement or in any option agreement to
the contrary, upon a Change of Control, any stock options granted to you after
the date hereof (previous options being governed by Executive's prior
agreements) shall accelerate and become vested without further action and, to
the extent permitted under the plan's governing documents, Executive shall have
a period of one year from the date of termination to exercise such options.

      6.    CHANGE OF CONTROL DEFINED.

      For purposes of this Agreement, the term "Change of Control" shall mean
and include the following transactions or situations:

      (a) The acquisition of beneficial ownership, directly or indirectly, of
securities having 33% or more of the combined voting power of Meritage's then
outstanding securities by any "Unrelated Person" or "Unrelated Persons" acting
in concert with one another. For purposes of

                                       2
<PAGE>
this Section, the term "Person" shall mean and include any individual,
partnership, joint venture, association, trust, corporation, or other entity
(including a "group" as referred to in Section 13(d)(3) of the Securities
Exchange Act of 1934 (the "Act"). For purposes of this Section, the term
"Unrelated Person" shall mean and include any Person other than the Company, or
an employee benefit plan of the Company, or any officer, director, or 10% or
more shareholder of the Company as of the date of this Agreement.

      (b) A sale, transfer, or other disposition through a single transaction or
a series of transactions of all or substantially all of the assets of Meritage
to an Unrelated Person or Unrelated Persons acting in concert with one another.

      (c) Any consolidation or merger of Meritage with or into an Unrelated
Person, unless immediately after the consolidation or merger the holders of the
common stock of Meritage immediately prior to the consolidation or merger are
the Beneficial Owners of securities of the surviving corporation representing at
least 50% of the combined voting power of the surviving corporation's then
outstanding securities.

      (d) A change during any period of two consecutive years of a majority of
the members of the Board of Directors of Meritage for any reason, unless the
election, or the nomination for election by the Company's shareholders, of each
director was approved by the vote of a majority of the directors then still in
office who were directors at the beginning of the period.

      7.    GOOD REASON DEFINED.

      For purposes of this Agreement, the term "Good Reason" shall include the
following circumstances: (a) if the Company assigns you duties that are
materially inconsistent with, or constitute a material reduction of powers or
functions associated with, your position, duties, or responsibilities with the
Company, or a material adverse change in your titles, authority, or reporting
responsibilities, or in conditions of your employment, (b) if your base salary
is reduced or the potential incentive compensation (or bonus) to which you may
become entitled to at any level of performance by you or the Company is reduced,
(c) if the Company fails to cause any successor to expressly assume and agree to
be bound by the terms of this Agreement, (d) any purported termination by the
Company of your employment for grounds other than for "Cause," (e) if the
Company relieves you of your duties other than for "Cause," or (f) if you are
required to relocate to an employment location that is more than fifty (50)
miles from _________, __________. The Company and you further acknowledge and
agree that, if following a Change of Control, you do not serve or are not
serving as Co-Chairman and Chief Executive Officer (or sole Chairman and Chief
Executive Officer) of the parent corporation of the surviving organization, you
have experienced a material reduction of powers or functions associated with
your position, duties or responsibilities with the Company such that Good Reason
shall be deemed to exist.

                                       3
<PAGE>
      8.    CAUSE DEFINED.

      For purposes of this Agreement, the term "Cause" will exist if you have
engaged in malfeasance that materially harms the Company or its stockholders, or
if you are convicted of a felony that is materially detrimental to the Company
or its stockholders.

      9.    [RESERVED].

      10.   TERMINATION NOTICE AND PROCEDURE.

      Any termination by the Company or you of your employment shall be
communicated by written Notice of Termination to you if such Notice of
Termination is delivered by the Company and to the Company if such Notice of
Termination is delivered by you, all in accordance with the following
procedures:

            (a) The Notice of Termination shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances alleged to provide a basis for
termination.

            (b) Any Notice of Termination by the Company shall be in writing
signed by the Co-Chairman of the Board of Meritage (other than you) specifying
in detail the basis for such termination.

            (c) If the Company shall furnish a Notice of Termination for Cause
and you in good faith notify the Company that a dispute exists concerning such
termination within the 30-day period following your receipt of such notice, you
may elect to continue your employment (or you may be placed on paid
administrative leave, at the Company's option), during such dispute. If it is
thereafter determined that (i) Cause did exist, your "Termination Date" shall be
the earlier of (A) the date on which the dispute is finally determined, either
by mutual written agreement of the parties or pursuant to the alternative
dispute resolution provisions of Section 17, or (B) the date of your death; or
(ii) Cause did not exist, your employment shall continue as if the Company had
not delivered its Notice of Termination and there shall be no Termination Date
arising out of such notice.

            (d) If the Company shall furnish a Notice of Termination by reason
of Disability and you in good faith notify the Company that a dispute exists
concerning such termination within the 30-day period following your receipt of
such notice, you may elect to continue your employment during such dispute. The
dispute relating to the existence of a Disability shall be resolved by the
opinion of the licensed physician selected by Meritage, provided, however, that
if you do not accept the opinion of the licensed physician selected by Meritage,
the dispute shall be resolved by the opinion of a licensed physician who shall
be selected by you; provided further, however, that if Meritage does not accept
the opinion of the licensed physician selected by you, the dispute shall be
finally resolved by the opinion of a licensed physician selected by the licensed
physicians selected by Meritage and you, respectively. If it is thereafter
determined that (i) a Disability did exist, your Termination Date shall be the
earlier of (A) the date on which the dispute is resolved, or (B) the date of
your death, or (ii) a Disability did not exist, your employment shall continue
as if the Company had not

                                       4
<PAGE>
delivered its Notice of Termination and there shall be no Termination Date
arising out of such notice. For purposes of this Agreement, "Disability" shall
be given the meaning ascribed to such term in your Employment Agreement at the
time the Disability determination is being made.

            (e) If you in good faith furnish a Notice of Termination for Good
Reason and the Company notifies you that a dispute exists concerning the
termination within the 30-day period following the Company's receipt of such
notice, you may elect to continue your employment (or you may be placed on paid
administrative leave, at the Company's option), during such dispute. If it is
thereafter determined that (i) Good Reason did exist, your Termination Date
shall be the earlier of (A) the date on which the dispute is finally determined,
either by mutual written agreement of the parties or pursuant to the alternative
dispute resolution provisions of Section 17, (B) the date of your death, or (C)
one day prior to the second anniversary of a Change of Control, and your
payments hereunder shall reflect events occurring after you delivered Notice of
Termination; or (ii) Good Reason did not exist, your employment shall continue
after such determination as if you had not delivered the Notice of Termination
asserting Good Reason.

            (f) If you do not elect to continue employment pending resolution of
a dispute regarding a Notice of Termination, and it is finally determined that
the reason for termination set forth in such Notice of Termination did not
exist, if such notice was delivered by you, you shall be deemed to have
voluntarily terminated your employment other than for Good Reason and if
delivered by the Company, the Company will be deemed to have terminated you
other than by reason of Disability or Cause.

      11.   SUCCESSORS.

      Meritage will require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business and/or assets of Meritage or any of its subsidiaries to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that Meritage or any subsidiary would be required to perform it if no
such succession had taken place. Failure of Meritage to obtain such assumption
and agreement prior to the effectiveness of any such succession shall be a
breach of this Agreement and shall entitle you to compensation in the same
amount and on the same terms to which you would be entitled hereunder if you
terminate your employment for Good Reason following a Change of Control, except
that for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the Termination Date. As used in
this agreement "Company" shall mean Company, as hereinbefore defined and any
successor to its business and/or assets as aforesaid which assumes and agrees to
perform this Agreement by operation of law or otherwise.

      12.   BINDING AGREEMENT.

      This Agreement shall inure to the benefit of and be enforceable by you and
your personal or legal representatives, executors, administrators, successors,
heirs, distributees, devisees and legatees. If you should die while any amount
would still be payable to you hereunder had you continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance

                                       5
<PAGE>
with the terms of this Agreement to your devisee, legatee or other designee or,
if there is no such designee, to your estate.

      13.   NOTICE.

      For purposes of this Agreement, notices and all other communications
provided for in this Agreement shall be in writing and shall be deemed to have
been duly given when delivered or mailed by United States certified or
registered mail, return receipt requested, postage prepaid, addressed as shown
in the Employment Agreement, provided that all notices to Meritage shall be
directed to the attention of the Chairman of the Board of Meritage with a copy
to the Secretary of Meritage, or to such other address as either party may have
furnished to the other in writing in accordance herewith, except that notice of
change of address shall be effective only upon receipt.

      14.   MISCELLANEOUS.

      No provision of this Agreement may be modified, waived or discharged
unless such waiver, modification or discharge is agreed to in writing and signed
by you and the Chairman of the Board of Meritage. No waiver by either party
hereto at any time of any breach by the other party hereto of, or compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or at any prior or subsequent time. No agreement or representations,
oral or otherwise, express or implied, with respect to the subject matter hereof
have been made by either party which are not expressly set forth in this
Agreement. The validity, interpretation, construction and performance of this
Agreement shall be governed by the laws of the State of __________ without
regard to its conflicts of law principles. All references to sections of the Act
or the Code shall be deemed also to refer to any successor provisions to such
sections. Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law. The
obligations of Meritage that arise prior to the expiration of this Agreement
shall survive the expiration of the term of this Agreement.

      15.   VALIDITY.

      The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of any other provision of this
Agreement, which shall remain in full force and effect.

      16.   COUNTERPARTS.

      This Agreement may be executed in several counterparts, each of which
shall he deemed to be an original but all of which together will constitute one
and the same instrument.

      17.   ALTERNATIVE DISPUTE RESOLUTION.

      All claims, disputes and other matters in question between the parties
arising under this Agreement shall, unless otherwise provided herein (such as in
Sections 9 and 10(d)), be resolved in accordance with the arbitration or
alternative dispute resolution provisions included in your Employment Agreement.

                                       6
<PAGE>
      18.   EXPENSES AND INTEREST.

      If a good faith dispute shall arise with respect to the enforcement of
your rights under this Agreement or if any arbitration or legal proceeding shall
be brought in good faith to enforce or interpret any provision contained herein,
or to recover damages for breach hereof, and you are the prevailing party, you
shall recover from the Company any reasonable attorneys' fees and necessary
costs and disbursements incurred as a result of such dispute or legal
proceeding, and prejudgment interest on any money judgment obtained by you
calculated at the rate of interest announced by Bank of America, Arizona from
time to time as its prime rate from the date that payments to you should have
been made under this Agreement, provided that such interest rate shall not be
less than eight percent. It is expressly provided that the Company shall in no
event recover from you any attorneys' fees, costs, disbursements or interest as
a result of any dispute or legal proceeding involving the Company and you.

      19.   PAYMENT OBLIGATIONS ABSOLUTE.

      Meritage's obligation to pay you the compensation and to make the
arrangements in accordance with the provisions herein shall be absolute and
unconditional and shall not be affected by any circumstances. All amounts
payable by Meritage in accordance with this Agreement shall be paid without
notice or demand. If Meritage has paid you more than the amount to which you are
entitled under this Agreement, Meritage shall have the right to recover all or
any part of such overpayment from you or from whomsoever has received such
amount.

      20.   EFFECT ON EMPLOYMENT AGREEMENT.

      This Agreement supplements, and does not replace, your Employment
Agreement, as it may be amended or replaced from time to time (the "Employment
Agreement"). If there is any conflict between the provisions of this Agreement
and your Employment Agreement, such conflict shall be resolved so as to provide
the greater benefit to you. However, the Company does not intend to provide
duplicative benefits with its employment agreement. As a result, benefits
otherwise receivable pursuant to this Agreement shall be reduced or eliminated
if and to the extent that you receive severance, consulting or non-competition
payments or benefits pursuant to any employment agreement you may have with the
Company.

      21.   ENTIRE AGREEMENT.

      This Agreement, your Employment Agreement and your option grant documents
set forth the entire agreement between you and the Company concerning the
subject matter discussed in this Agreement and supersede all prior agreements,
promises, covenants, arrangements, communications, representations, or
warranties, whether written or oral, by any officer, employee or representative
of the Company. Any prior agreements or understandings with respect to the
subject matter set forth in this Agreement are hereby terminated and canceled.
Notwithstanding the foregoing, nothing in this Agreement is intended to affect
any previous agreements pertaining to the grant of options to the Executive,
including without limitation, provisions set forth in Executive's prior Change
of Control Agreement providing for acceleration upon a change-in-control.

                                       7

      22.   DEFERRAL OF PAYMENTS.

      To the extent that any payment under this Agreement, when combined with
all other payments received during the year that are subject to the limitations
on deductibility under Code Section 162(m), exceeds the limitations on
deductibility under Code Section 162(m), such payment shall, in the discretion
of Meritage, be deferred to the next calendar year. The determination of
deductibility under the preceding sentence shall be made by legal counsel,
certified public accountants, and/or executive compensation consultants selected
by Meritage but who shall be reasonably acceptable to you. Meritage will notify
you as soon as it becomes aware of specific information that may cause it to
exercise its discretion to require deferral and shall provide you with access to
all information on which its decision is based. If the date for payment of any
amount is deferred pursuant to this Section 22, then Meritage will transfer an
amount in cash equal to the deferred amount to a trust which shall be in
substantially the same form as is set forth in Revenue Procedure 92-64, 1992-2
C.B. 422. The terms of the trust, including the designation of trustee, shall be
determined by Meritage but shall be reasonably acceptable to you. All deferred
amounts held in the trust shall bear interest at the greater of the rate of
interest announced by Bank of America, Arizona from time to time as its prime
rate or 8%, from the date that the payment would have been made to you but for
this Section 22 to the date that such payment is actually made to you. Payment
of the deferred amounts shall be made no later than the 30th day after the end
of the calendar year in which the deferral occurs, provided that such payment,
when combined with any other payments subject to the Section 162(m) limitations
received during the year, does not exceed the limitations on deductibility under
Code Section 162(m).

      23.   PARTIES.

      This Agreement is an agreement between you and Meritage and all successors
and assigns of Meritage. In certain cases, though, obligations imposed upon
Meritage may be satisfied by a subsidiary of Meritage. Any payment made or
action taken by a subsidiary of Meritage shall be considered to be a payment
made or action taken by Meritage for purposes of determining whether Meritage
has satisfied its obligations under this Agreement.

themselves  individually  and not as to any other Investor,  makes the following
representations, warranties and covenants.

         corporate  or  partnership  power  and  authority  to enter  into  this
         Conversion  Commitment  Agreement  and to consummate  the  transactions
         contemplated  hereunder.  Neither the  execution  and  delivery of this
         Conversion   Commitment   Agreement,   nor  the   consummation  of  the
         transactions  contemplated  hereunder conflicts with, or will result in
         any  violation of (a) the charter,  by-laws,  partnership  agreement or
         other organizational  documents of such Investor,  each as currently in
         effect,  or (b) any  material  loan or credit  agreement,  note,  bond,
         mortgage,  indenture,  lease, contract or other agreement to which such
         Investor is a party or by which any of its assets are bound.

         B. Authorization and Execution.  This Conversion  Commitment  Agreement
         has been duly and validly  authorized,  executed  and  delivered by the
         Investors and is a valid and binding agreement of each of the Investors
         enforceable  against  it in  accordance  with  its  terms,  subject  to
         applicable    bankruptcy,     insolvency,     fraudulent    conveyance,
         reorganization, moratorium and similar laws affecting creditors' rights
         and remedies generally.

         C.  Approvals.  No  authorization,  approval or consent of any court or
         public or  governmental  authority  is  required  to be obtained by the
         Investors for the execution of this Conversion  Commitment Agreement or
         the consummation of the transactions  contemplated hereby,  except such
         authorizations,  approvals  and  consents as have been  obtained by the
         Investors prior to the date hereof.

         D. Investment Intent. Each Investor purchased or acquired the shares of
         Preferred Stock for its own account,  for investment  purposes only and
         not  with a view  towards  or in  connection  with the  public  sale or
         distribution  thereof in violation of the Securities Act. Each Investor
         is acquiring the Shares for its own account,  for  investment  purposes
         only and not with a view towards or in connection  with the public sale
         or distribution thereof in violation of the Securities Act.

         E. Accredited Investor.  Each Investor is (i) an "accredited  investor"
         within the  meaning of Rule 501 of  Regulation  D under the  Securities
         Act, (ii) experienced in making  investments in securities with similar
         risks as the Shares,  (iii)  capable,  by reason of their  business and
         financial experience, of evaluating the relative merits and risks of an
         investment  in the  Shares,  and (iv)  able to  afford  the loss of its
         investment in the Shares.

         F. Unregistered  Securities.  Each Investor understands that the Shares
         have not been approved or  disapproved  by the  Securities and Exchange
         Commission (the  "Commission") or any state  securities  commission and
         that the Shares are being  offered  and sold by the Company in reliance
         on an exemption from the  registration  requirements  of the Securities
         Act and any relevant state  securities and "blue sky" laws. The Company
         is relying upon the accuracy of, Investors' compliance with, Investors'
         representations,  warranties and covenants set forth in this Conversion
         Commitment  Agreement to determine the  availability  of such exemption
         and the eligibility of the Investors to acquire the Shares.

         G. Access to Information.  Each Investor has received and has carefully
         reviewed a copy of the  documents  and reports (and  exhibits  thereto)
         filed  by  the  Company  with  the  Commission  and  available  on  the
         Commission's EDGAR system,  including,  but not necessarily limited to,
         the Company's  Annual Report or Form 10-KSB for the year ended December
         31, 2002,  the Quarterly  Report on Form 10-QSB for the fiscal  quarter
         ended since then, the Proxy Statement for the stockholder  meeting held
         in April 2003 (collectively,  the "Documents").  Each Investor has also
         received any additional information that the Investor has requested and
         has had the  opportunity to  communicate  with  representatives  of the
         Company,  to each Investor's  satisfaction and understands the material
         contained in the Documents. Each Investor realizes that the purchase of
         the  Shares  is a  speculative  investment,  and that the tax and other
         economic  benefits  that may be derived  therefrom  are  uncertain.  In
         determining  whether or not to proceed with the  transaction  described
         herein,  each Investor has relied solely upon  information set forth in
         the  Documents  and  upon  independent   investigations  made  by  such
         Investor.  None of the  Investors  have been  furnished  with any other
         offering  literature or prospectus,  or received or been furnished with
         any information,  statement or  representation,  oral or written,  that
         varies  in  any  material  way  from  the  information   presented  and
         statements made in the Documents.

         and/or  Rule 144 in  connection  with the offer and sale of the  Common
         Shares as contemplated hereby.
