pursue any other remedy in its power, before being entitled to payment from the

proceeding against the Guarantors; (b) the defense of the statute of limitations
in any action hereunder or for the collection of any Indebtedness or the

federal Bankruptcy Code; (d) diligence, presentment, demand for payment,
protest, notice of discharge, notice of acceptance of this Guaranty, and

otherwise impairs any subrogation rights of the Guarantors or the right of the
Guarantors to proceed against the Borrower for reimbursement, or both; (f) any
defense based upon any taking, modification or release of any collateral or
guaranties for the Indebtedness of the Borrower to the Banks and the Agents, or

appraisement with regard to the value of any collateral which the Banks may

the Guarantors shall remain fully liable, as principal, until the full payment
of the Indebtedness, full performance of all the Obligations, and termination of
the obligations of the Banks and the Agents under the Loan Documents,
notwithstanding any act, omission or thing which might otherwise operate as a

performance of any agreement, covenant, term or condition contained in the
Loan Documents; or (h) the foreclosure of any lien or security interest on
any property securing repayment of the Indebtedness, or the acceptance of a
deed or assignment of any such property in lieu of foreclosure; or (i) any
action which the Holder may take or omit to take by virtue of the Loan
Documents or through any course of dealing with the Borrower; or (j) the
release of any existing guarantor or the addition of a new guarantor; or (k)

         6. WAIVER OF SUBROGATION. The Guarantors hereby waive, release and
discharge any claim or right the Guarantors may have to be subrogated to the

the Indebtedness has been paid in full, the Obligations performed, and the
obligations of the Banks and the Agents under the Loan Documents terminated.

         7. SUBORDINATION OF INDEBTEDNESS. Any indebtedness of the Borrower now
or hereafter held by any Guarantor is hereby subordinated to the Indebtedness of
the Borrower to the Holder; and, upon the request of the Holder, such
indebtedness of the Borrower to the Guarantors shall be collected, enforced and
received by the Guarantors as trustee for the Holder and shall be paid over to
the Holder on account of the Indebtedness of the Borrower to the Holder without
reducing or affecting in any manner the liability of the Guarantors under the
other provisions of this Guaranty.

         8. CLAIMS IN BANKRUPTCY. The Guarantors will file all claims against
the Borrower in any bankruptcy or other proceeding in which the filing of claims
is required or permitted by law upon any indebtedness of the Borrower to any
Guarantor or claim against the Borrower by any Guarantor, and the Guarantors
hereby assign to the Banks and the Agents all rights of the Guarantors
thereunder. If the Guarantor does not file any such claim, the Banks and the
Agents, as attorney-in-fact for such Guarantor, is hereby authorized to do so in
the name of the Guarantor or, in the discretion of the Banks and the Agents, to
assign the claim and to cause proof of claim to be filed in the name of the
nominee of the Banks and the Agents. The Banks, the Agents or their nominee
shall have the sole right to accept or reject any plan proposed in such
proceeding and to take any other action which a party filing a claim is entitled
to take. In all such cases, whether in administration, bankruptcy or otherwise,
the person or persons authorized to pay such claim shall pay to the Banks and
the Agents the full amount payable on such claim up to the amounts due under
this Guaranty, and, to the full extent necessary for that purpose, the
Guarantors hereby assign to the Banks and the Agents all of the Guarantors'
rights to any such payments or distributions to which the Guarantors would
otherwise be entitled; provided, however, that the Guarantors' obligations
hereunder shall not be satisfied except to the extent that


                                 4
<PAGE>


the Banks and the Agents receive cash by reason of any such payment or
distribution. If the Banks and the Agents receive anything hereunder other
than cash, the same shall be held as collateral for the payment of all
amounts due under this Guaranty.

         9.  FINANCIAL CAPACITY.

         (a) The Guarantors hereby agree, as a material inducement to the Banks
and the Agents to enter into the Credit Agreement, to furnish to the Banks and
the Agents such financial statements, reports and information as required by
Sections 6.01 and 6.02 of the Credit Agreement. The Banks and the Agents agree
to keep confidential all of the financial information which it receives in
connection herewith, except that such information may be provided to any
assignee as provided in Section 17 hereof.

         (b) The Guarantors will promptly notify each Bank through the
Administrative Agent of the commencement of, or any material development in, any
litigation or proceeding affecting any Guarantor which, if adversely determined,
would reasonably be expected to have a Material Adverse Effect (as defined in
the Credit Agreement); or in which the relief sought is an injunction or other
stay of the performance of this Guaranty. Such notice shall be accompanied by a
written statement by the chief executive officer, the president or the chief
financial officer of such Guarantor, or any other officer having substantially
the same authority and responsibility, setting forth details of the occurrence
referred to therein, and stating what action the Guarantors propose to take with
respect thereto and at what time.

         10. CONDITION OF BORROWER. The Guarantors are fully aware of the
financial condition of the Borrower and are executing and delivering this
Guaranty based solely upon the Guarantors' own independent investigation of all
matters pertinent hereto, and are not relying in any manner upon any
representation or statement of the Banks or the Agents. The Guarantors represent
and warrant that the Guarantors are in a position to obtain and the Guarantors
hereby assume full responsibility for obtaining, any additional information
concerning the Borrower's financial condition and any other matter pertinent
hereto as the Guarantors may desire, and the Guarantors are not relying upon or
expecting the Banks or the Agents to furnish to the Guarantors any information
now or hereafter in the possession of the Banks or the Agents concerning the
same or any other matter. By executing this Guaranty, the Guarantors knowingly
acknowledge and accept the full range of risks encompassed within a contract of
this type. The Guarantors shall have no right to require the Banks or the Agents
to obtain or disclose any information with respect to the Indebtedness or the
Obligations, the financial condition or character of the Borrower, the
Borrower's ability to pay the Indebtedness or perform the Obligations, the
existence of any collateral or security for any or all of the Indebtedness or
the Obligations, the existence or non-existence of any other guaranties of all
or any part of the Indebtedness or the Obligations, or any action or non-action
on the part of the Banks, the Agents, the Borrower, or any other person, or any
other matter, fact or occurrence whatsoever.

         11.  REPRESENTATIONS  AND WARRANTIES. Each of the Guarantors represents
and warrants to the Banks and the Agents that:

         (a) TAX RETURNS AND PAYMENTS. All material tax returns and reports of
each Guarantor required by law to be filed have been duly filed, and all taxes,
assessments, contributions, fees


                                      5
<PAGE>


and other governmental charges the liability for which could exceed $100,000
(other than those currently payable without penalty or interest and those
currently being contested in good faith) upon any Guarantor or upon any
Guarantor's properties, assets or income which are due and payable have been
paid.

         (b) LITIGATION. There is, to the knowledge of the Guarantors, no
action, suit, proceeding or investigation pending at law or in equity or before
any Governmental Authority (as defined in the Credit Agreement), or threatened
against or affecting any Guarantor, an adverse ruling in which would or might
materially impair the ability of the Guarantors to observe and perform the
Guarantors' obligations under this Guaranty or have a material adverse effect
upon the legality, validity, binding effect or enforceability of this Guaranty.

         (c) COMPLIANCE WITH OTHER INSTRUMENTS; NONE BURDENSOME. To the best of
their knowledge, no Guarantor is in violation of or in default with respect to
any provision of any mortgage, indenture, contract, agreement or instrument
applicable to such Guarantor, or by which such Guarantor is bound, and there is
no provision of any mortgage, indenture, contract, agreement or instrument
applicable to any Guarantor or by which any Guarantor is bound which materially
adversely affects, or in the future (so far as the Guarantors can now foresee)
will materially adversely affect, the business or prospects or condition
(financial or other) of any Guarantor or of any Guarantor's properties or
assets.

         (d) FINANCIAL STATEMENTS. Any financial statements heretofore delivered
to the Banks and the Agents by the Guarantors are true and correct in all
respects, and fairly represent the respective financial conditions of the
subjects thereof as of the respective dates thereof; and no materially adverse
change has occurred in the financial conditions reflected therein since the
respective dates thereof.

         12. BANKRUPTCY. Until all Indebtedness has been paid to the Banks and
the Agents, all Obligations have been performed, and the obligations of the
Banks and the Agents under the Loan Documents have been terminated, the
Guarantors shall not, without the prior written consent of the Banks and the
Agents, commence or join with any other person in commencing any bankruptcy,
reorganization or insolvency proceedings of or against the Borrower. The
obligations of the Guarantors under this Guaranty shall not be altered, limited
or affected by any proceeding, voluntary or involuntary, involving the
bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement
of the Borrower or by any defense which the Borrower may have by reason of the
order, decree or decision of any court or administrative body resulting from any
such proceeding. The Guarantors acknowledge and agree that any interest on the
Indebtedness which accrues after the commencement of any such proceeding (or, if
interest on any portion of the Indebtedness ceases to accrue by operation of law
by reason of the commencement of said proceeding, such interest as would have
accrued on any such portion of the Indebtedness if said proceeding had not been
commenced) shall be included in the Indebtedness, since it is the intention of
the parties that the amount of the Indebtedness which is guaranteed by the
Guarantors pursuant to this Guaranty should be determined without regard to any
rule of law or order which may relieve the Borrower of any portion of such
Indebtedness. The Guarantors will permit any trustee in bankruptcy, receiver,
debtor in possession, assignee for the benefit of creditors or similar person to
pay the Banks and the Agents, or allow the claim of the Banks and the Agents in
respect of, any such interest accruing after the date on which such proceeding
is commenced. In the event that all or any portion of the Indebtedness is paid
or all


                                6
<PAGE>


or any part of the Obligations are performed by the Borrower, the obligations
of the Guarantors hereunder shall continue and remain in full force and
effect in the event that all or any part of such payment or performance is
avoided or recovered directly or indirectly from the Banks or the Agents as a
preference, fraudulent transfer or otherwise in such proceeding.

         13. REMEDIES CUMULATIVE. The liability of the Guarantors, and all
rights, powers and remedies of the Banks and the Agents hereunder and under any
other agreement now or at any time hereafter in force between the Banks, the
Agents and the Guarantors relating to the Indebtedness or the Obligations, shall
be cumulative and not exclusive or alternative, and such rights, powers and
remedies shall be in addition to all other rights, powers and remedies given to
the Banks and the Agents by law.

         14. AMENDMENTS; CONTINUING LIABILITY. The terms of this Guaranty may
not be modified or amended except by a written agreement executed by the
Guarantors with the consent in writing of the Holder. The obligations of the
Guarantors under this Guaranty shall be continuing obligations and a separate
cause of action shall be deemed to arise in respect of each default hereunder.
The Guarantors will from time to time deliver, upon request of the Holder,
satisfactory acknowledgments of the Guarantors' continued liability hereunder.

         15. MERGER OR CONSOLIDATION OF GUARANTORS; MERGER OF THE BORROWER. No
Guarantor will consolidate or merge with or into another corporation, person or
entity, whether or not affiliated with such Guarantor without the written
consent of the Holder (which consent shall not be unreasonably withheld). No
consolidation or merger (with or without the consent of the Holder) shall
release, affect or impair the continuing liability and obligation of the
Guarantors under this Guaranty. This section shall not prohibit the anticipated
merger (the "Schuler Merger") of the Borrower, Schuler Homes, Inc. which will
then be known as Schuler Residential, Inc., into Schuler Holdings, Inc., which
will then be known as Schuler Homes, Inc. ("Merger Borrower"), pursuant to that
certain Reorganization Plan (as described in the Credit Agreement). Upon the
completion of the Schuler Merger, the Merger Borrower shall assume the
obligations of the Borrower under the Credit Facility and shall execute a Fifth
Amended and Restate Credit Agreement (the "Fifth Credit Agreement"), in the form
as presented to the Guarantors. The Guarantors hereby consent to the Fifth
Credit Agreement and acknowledge and agree that the execution of the Fifth
Credit Agreement by the Merger Borrower shall not in any way affect, impair, or
diminish any of their obligations under this Guaranty, all of which shall
continue to apply to the Fifth Credit Agreement.

         16. NOTICES.  Any notice or demand to be given or served hereunder
shall be in writing and personally  delivered, or sent by registered or
certified mail addressed as follows:

the above provisions. Any such FAX transmission shall, at the Agents' request,

all or any portion of the Indebtedness or the Obligations without notice to or
consent of the Guarantor, and when so assigned, the Guarantors shall be liable
to the assignee as to any such portion, without in any manner affecting the
liability of the Guarantors with respect to any of the Indebtedness or
Obligations retained by the Banks or the Agents.

shall be construed and interpreted in accordance with and shall be governed by

that the Guarantors will submit and does hereby irrevocably submit to the
personal jurisdiction of such courts; if served by mail will acknowledge receipt

CONVENIENS or similar grounds; provided, however, that nothing contained herein
shall prohibit the Guarantors from seeking, by appropriate motion, to remove an
action brought in a Hawaii state court to the United States District Court for
the District of Hawaii. If such action is so removed, however, the Guarantors
shall not seek to transfer such action to any other district nor shall the

the Agents originally commenced in the United States District Court for the
District of Hawaii. Any action or proceeding brought by the Guarantors arising
out of this Guaranty shall be brought solely in a court of competent
