     employment, consulting activity or business other than for the Company.

(b)  Activity as a passive investor in, or outside director for, another
     business enterprise shall not be considered in breach of this section so
     long as such business enterprise is competing against or conducting
     business with the Company. Any such activity shall not adversely impact the
     performance of Mr. Jackson in fulfilling his duties to the Company.

10. NON-COMPETE

The parties acknowledge that Mr. Jackson, as a result of his status as a founder
and executive employee, shall substantively contribute to and shall acquire
significant knowledge and information concerning the business of the Company and
its Customers. The parties further acknowledge that the scope of business in
which the Company is engaged is worldwide and very competitive, and that such
business is one in which few companies can compete successfully. The parties
also acknowledge that competition from Mr. Jackson in that business would be
detrimental and harmful to the Company. Accordingly, Mr. Jackson agrees that
during the term of this Agreement, and for a period of 1 year following the
termination of this Agreement, Mr. Jackson shall not:

(a)  Directly or indirectly, sell or attempt to sell products or services for or
     on behalf of any business that manufactures, assembles, distributes, offers

     the Company at any time during the term of this Agreement. If Mr. Jackson

agreement, whether express, implied, oral, or written, that poses an impediment
to Mr. Jackson's employment by the Company including Mr. Jackson's compliance
with the terms of this Agreement. In particular, Mr. Jackson is not subject to a
pre-existing non-competition agreement and no restrictions or limitations exist
respecting Mr. Jackson's ability to perform fully his duties for the Company.

12. INJUNCTIVE RELIEF

Both parties acknowledge that a breach of this Agreement is likely to result in
irreparable and unreasonable harm to the party not in breach. Both parties
further acknowledge that damages caused by a breach would be extremely difficult
to calculate, and that injunctive relief, as well as damages, would be
appropriate.

13. SUCCESSORS AND ASSIGNS

This Agreement shall be binding upon Mr. Jackson, his heirs, executors, assigns
and administrators and shall inure to the benefit of the Company, its
successors, and assigns.

the provisions of this Agreement thus affected shall be curtailed and limited
only to the extent necessary to bring it within the requirements of the law. If
any part of this Agreement shall be held by a court of proper jurisdiction to be
indefinite, invalid or otherwise unenforceable, the entire Agreement shall not
fail on account thereof, but:

     1.   The balance of the Agreement shall continue in full force and effect
          unless such construction would clearly be contrary to the intention of
          the parties or would result in unconscionable injustice; and
     2.   The court shall amend the Agreement to the extent necessary to make
          the Agreement valid and enforceable.

       Agreement (including Section 8.2), at any time and from time to time from
       the Closing Date through the Banking Day immediately preceding the
       Maturity Date, each Bank shall, pro rata according to that Bank's Pro
       Rata Share of the Commitment then in effect, make Advances to Borrower in
       such amounts as Borrower may request; provided that after giving effect
       to such Advance, the aggregate outstanding principal evidenced by the
       Notes shall not exceed the Commitment. Subject to the limitations set
       forth herein, Borrower may borrow, repay and reborrow under this Section
       2.1(a) without premium or penalty.

                     (b) Subject to the next sentence, each Loan shall be made
       pursuant to a Request for Loan which shall be in a form and shall contain

       (ii) type of Loan, (iii) amount of such Loan and (iv) in the case of a
       LIBOR Loan, Interest Period for such Loan. Unless the Administrative
       Agent, in its sole and absolute discretion, has notified Borrower to the
       contrary, each Loan may be requested by telephone (promptly confirmed in
       writing) or telecopier by a Responsible Official of Borrower, and
       Borrower shall confirm such request by promptly mailing a Request for
       Loan conforming to the preceding sentence to the Administrative Agent.

                     (c) Promptly following receipt of a Request for Loan, the
       Administrative Agent shall notify each Bank by telephone, telecopier or
       telex of the date and type of the Loan, the applicable Interest Period in
       the case of an LIBOR Loan, and that Bank's Pro Rata Share of the Loan.
       Not later than 11:00 a.m., California time, on the date specified for any

       Bank to make any Advance is several, and not joint or joint and several,
       and is not conditioned upon the performance by any other Bank of its
       obligation to make Advances. The failure by any Bank to perform its
       obligation to make any Advance will not increase the obligation of any
       other Bank to make Advances.

       a LIBOR Loan, or a LIBOR Loan as an Alternate Base Rate Loan or a LIBOR
       Loan with a new Interest Period, by delivering a Request for
       Redesignation to the Administrative Agent, within the time periods and
       pursuant to the conditions set forth in Section 2.1(b), 2.2 or 2.3, as

       periods set forth in Section 2.3, then Borrower shall be deemed to have
       requested that such LIBOR Loan be redesignated as an Alternate Base Rate
       Loan.

       Market Days before the first day of the applicable Interest Period, the
       Administrative Agent shall determine the applicable LIBOR (which
       determination shall be conclusive in the absence of manifest error) and
       promptly shall give notice of the same to Borrower and the Banks by
       telephone, telecopier or, in the case of the Banks, telex.

                     (c) No more than three (3) LIBOR Loans may be outstanding
       at any particular time.

Agent on the date of such termination all unpaid commitment fees which have
accrued to such date in respect of the terminated portion of the Commitment.

              2.7 Administrative Agent's Right to Assume Funds Available. Unless
the Administrative Agent shall have been notified by any Bank at least two hours
prior to the funding by the Administrative Agent of any Loan that such Bank does
not intend to make available to the Administrative Agent such Bank's Pro Rata
Share of such Loan, the Administrative Agent may, in its discretion (but shall
not be so obligated), assume that such Bank has made such amount available to
the Administrative Agent on the date of the Loan and the Administrative Agent
may, in reliance upon such assumption, make available to Borrower a
corresponding amount. If such corresponding amount is not in fact made available
to the Administrative Agent by such Bank, the Administrative Agent shall be
entitled to recover such corresponding amount on demand from such Bank, which
demand shall be made in a reasonably prompt manner. If such Bank does not pay
such corresponding amount forthwith upon the Administrative Agent's demand
therefor, the Administrative Agent promptly shall notify Borrower and Borrower
shall pay such corresponding amount to the Administrative Agent. The
Administrative Agent shall also be entitled to recover from such Bank interest
on such corresponding amount in respect of each day from the date such
corresponding amount was made available by the Administrative Agent to Borrower
to the date such corresponding amount is recovered by the Administrative Agent,
at a rate per annum equal to the Federal Funds Rate as notified by the
Administrative Agent to such Bank or the Borrower, as the case may be. Nothing
herein shall be deemed to relieve any Bank from its obligation to fulfill its
Pro Rata Share of the Commitment hereunder or to prejudice any rights which the
Administrative Agent or Borrower may have against any Bank as a result of any
default by such Bank hereunder.

              happening of any contingency).

                     "Associate" shall have the meaning ascribed to such term in
              Rule 12b-2 of the General Rules and Regulations under the Exchange
              Act, as in effect on the date hereof.

                     (o) The occurrence of an Event of Default under the Primary
       Loan Agreement.

              9.2 Remedies Upon Event of Default. Without limiting any other
rights or remedies of the Administrative Agent or the Banks provided for
elsewhere in this Agreement or the Loan Documents, or by applicable Law or in
equity, or otherwise:

                     (a) Upon the occurrence of any Event of Default, and so
       long as any such Event of Default shall be continuing (other than an
       Event of Default described in Section 9.1(k) with respect to Borrower or
       a Guarantor Subsidiary):

                            (i) all commitments to make Advances and all other
                     obligations of the Administrative Agent or the Banks shall
                     be suspended without notice to or demand upon Borrower,
                     which are expressly waived by Borrower, except that the
                     Majority Banks may waive the Event of Default or, without
                     waiving, determine, upon terms and conditions satisfactory
                     to the Majority Banks, to reinstate the Commitments and
                     make further Advances, which waiver or determination shall
                     apply equally to, and shall be binding upon, all the Banks;
                     and

                            (ii) the Majority Banks may request the
                     Administrative Agent to, and the Administrative Agent
                     thereupon shall, declare the unpaid principal of all
                     Obligations due to the Banks hereunder and under the Notes,
                     all interest accrued and unpaid thereon, and all other
                     amounts payable to the Banks under the Loan Documents to be
                     forthwith due and payable, whereupon the same shall become
                     and be forthwith due and payable, without protest,
                     presentment, notice of dishonor, demand, or further notice
                     of any kind, all of which are expressly waived by Borrower;
                     provided that the Administrative Agent shall notify
                     Borrower (by telecopy and, if practicable, by telephone)
                     substantially concurrently with any such acceleration (but
                     the failure of Borrower to receive such notice shall not
                     affect such acceleration).

                     (b) Upon the occurrence of any Event of Default described
       in Section 9.1(k) with respect to Borrower or a Guarantor Subsidiary:

                            (i) all commitments to make Advances and all other
                     obligations of the Administrative Agent or the Banks under
                     the Loan Documents shall terminate without notice to or
                     demand upon Borrower, which are expressly waived by
                     Borrower, except that all the Banks may waive the Event of
                     Default or, without waiving, determine, upon terms and
                     conditions satisfactory to all the Banks, to reinstate the
                     Commitments and make further Advances; and

                            (ii) the unpaid principal of all Obligations due to
                     the Banks hereunder and under the Notes and all interest
                     accrued and unpaid on such Obligations, and all other
                     amounts payable under the Loan Documents shall be forthwith
                     due and payable, without protest, presentment, notice of
                     dishonor, demand, or further notice of any kind, all of
                     which are expressly waived by Borrower.

                     (c) [reserved]

                     (d) Upon the occurrence of an Event of Default, the Banks
       and the Administrative Agent, or any of them, may proceed to protect,
       exercise, and enforce their rights and remedies under the Loan Documents
       against Borrower or any other Party and such other rights and remedies as
       are provided by Law or equity, without notice to or demand upon Borrower
       (which are expressly waived by Borrower) except to the extent required by
       applicable Laws. The order and manner in which the rights and remedies of
       the Banks under the Loan Documents and otherwise are exercised shall be
       determined by the Majority Banks.

                     (e) All payments received by the Administrative Agent and
       the Banks, or any of them, after the acceleration of the maturity of the
       Loans shall be applied first to the costs and expenses (including
       attorneys' fees and disbursements) of the Administrative Agent, acting as
       Administrative Agent, and of the Banks and thereafter paid pro rata to
       the Banks in the same proportion that the aggregate of the unpaid
       principal amount owing on the Obligations of Borrower to each Bank, plus
       accrued and unpaid interest thereon, bears to the aggregate of the unpaid
       principal amount owing on all the Obligations, plus accrued and unpaid
       interest thereon. Regardless of how each Bank may treat the payments for
       the purpose of its own accounting, for the purpose of computing
       Borrower's Obligations, the payments shall be applied first, to the costs
       and expenses of the Administrative Agent, acting as Administrative Agent,
       and the Banks as set forth above, second, to the payment of accrued and
       unpaid fees hereunder and interest on all Obligations to the Banks, to
       and including the date of such application (ratably according to the
       accrued and unpaid interest on the Loans), third, to the ratable payment
       of the unpaid principal of all Obligations to the Banks, and fourth, to
       the payment of all other amounts then owing to the Administrative Agent
       or the Banks under the Loan Documents. Subject to Section 9.2(a)(i), no
       application of the payments will cure any Event of Default or prevent
       acceleration, or continued acceleration, of amounts payable under the
       Loan Documents or prevent the exercise, or continued exercise, of rights
       or remedies of the Banks hereunder or under applicable Law unless all
       amounts then due (whether by acceleration or otherwise) have been paid in
       full.

                                  May 10, 2000

Bank of America, N.A.
as Administrative Agent

The Banks Party to the Loan Agreement
  Referred to Below

              Re: Kaufman and Broad Home Corporation

Ladies and Gentlemen:

              We have acted as counsel to Kaufman and Broad Home Corporation, a
Delaware corporation ("Borrower"), in connection with the 2000 Bridge Loan
Agreement (the "Loan Agreement") dated as of May 10, 2000, by and among
Borrower; the Banks which are parties thereto; Bank of America, N.A., as
Administrative Agent; Banc of America Securities LLC as Lead Arranger and Sole
Book Manager (the "Arranger") (all such parties other than the Borrower are
collectively referred to herein as "Bank Parties").

              This opinion is furnished to you pursuant to Section 8.1(a)(v) of
the Loan Agreement. Terms not otherwise defined herein shall have the meanings
defined for such terms in the Loan Agreement.

              For the purposes of this opinion, we have examined originals, or
copies identified to our satisfaction as being true copies, of the following
documents:

              (a) The Loan Agreement;

                           (Exhibit C-1, Page 1 of 6)
<PAGE>   48

              (b) The Notes of even date herewith; and

              (c) The Subsidiary Guaranty.

              The documents described in (a) through (c) above are sometimes
referred to herein as the "Loan Documents".

              We have also examined such other corporate documents and records,
and other certificates, opinions and instruments and have conducted such
investigations as we have deemed necessary as a basis for the opinions expressed
below. As to factual matters relevant to our opinions expressed below, we have,
without independent investigation, relied upon certificates of public officials
and upon public records, and have further assumed and relied upon, without
independent investigation, the truth and accuracy of all factual representations
and warranties of all parties to the Loan Documents.

              We have assumed (i) all natural persons have legal capacity, (ii)
the genuineness of all signatures of all parties other than Borrower, (iii) the
conformity to authentic original documents of all documents submitted to us as
copies and the authenticity of all documents submitted to us as originals, (iv)
that each of the Guarantor Subsidiaries listed in Schedule 4.4 to the Loan
Agreement (the "Guarantor Subsidiaries") is duly organized, validly existing and
in good standing under the laws of its jurisdiction of incorporation or
organization and in each other jurisdiction where the conduct of its business or
the ownership of its Properties makes qualification or registration to transact
business necessary, (v) as to all parties other than the Borrower, the due
authorization, execution and delivery of the Loan Documents, (vi) the validity
and enforceability of the Loan Documents against all parties thereto other than
Borrower and the Guarantor Subsidiaries, (vii) that each of the Bank Parties has
the requisite power and authority, has obtained all necessary consents, licenses
and permits, has taken all necessary action and has complied with any and all
applicable laws with which such Bank Party is required to comply, in each case
relating to or affecting the matters and actions contemplated by the Loan
Documents, (viii) that each of the Bank Parties (other than the Arranger) is a
national bank, state bank or similar financial institution and is an exempt
lender under Article XV of the California Constitution or statutes enacted
pursuant thereto and (ix) that the Loan Documents have not been modified,
amended, terminated or revoked in any respect, and remain in full force and
effect as of the date hereof.

                           (Exhibit C-1, Page 2 of 6)
<PAGE>   49

              On the basis of the foregoing, and relying thereon, and with the
qualifications herein set forth, we are of the opinion that:

              1. Borrower is a corporation duly incorporated, validly existing
and in good standing under the General Corporation Law of the State of Delaware,
and its certificate of incorporation does not limit the term of its existence.

              2. Borrower has all requisite corporate power and authority to
conduct its business, to own and lease its Properties and to execute, deliver
and perform all of its obligations under the Loan Documents to which it is a
party.

              3. The execution, delivery, and performance by Borrower of the
Loan Documents to which it is a party have been duly authorized by all necessary
corporate action.

              4. The execution, delivery, and performance of the Loan Documents
by Borrower do not violate any provision of Borrower's certificate of
incorporation or bylaws, and the execution, delivery, and performance by
Borrower and each Guarantor Subsidiary of the Loan Documents to which it is a
party do not violate any Requirement of Law applicable to Borrower or such
Guarantor Subsidiary imposed by the laws of the United States of America or the
State of California that, in our experience, is normally applicable to general
business entities in relation to transactions of the type contemplated by the
Loan Documents.

              5. Except as have heretofore been obtained, no authorization,
consent, approval, order, license or permit from, or filing, registration, or
qualification with, or exemption from any of the foregoing from, any
Governmental Agency under any Requirement of Law imposed on Borrower or any
Guarantor Subsidiary by the laws of the United States of America or the State of
California, in each case as such Requirements of Law exist on the date hereof,
is or will be required to authorize or permit the execution, delivery and
performance by Borrower or any Guarantor Subsidiary of the Loan Documents to
which it is a party.

              6. Each of the Loan Documents to which Borrower or any Guarantor
Subsidiary is a party will, when executed and delivered by Borrower or such
Guarantor Subsidiary, as the case may be, constitute the legal, valid and
binding obligation of Borrower or such Guarantor Subsidiary, as the case may be,
enforceable against Borrower or such Guarantor Subsidiary, as the case may be,
in accordance with its terms.

                           (Exhibit C-1, Page 3 of 6)
<PAGE>   50

              In addition to any assumptions, qualifications and other matters
set forth elsewhere herein, the opinions set forth above are subject to the
following:

              (a) Our opinion with respect to the legality, validity, binding
effect and enforceability of any Loan Document, agreement or provision is
subject to the effect of any applicable bankruptcy, insolvency, fraudulent
conveyance, fraudulent transfer and equitable subordination, reorganization,
moratorium or similar law affecting creditors' rights generally and to the
effect of general principles of equity, including (without limitation) concepts
of materiality, reasonableness, estoppel, good faith and fair dealing
(regardless of whether considered in a proceeding in equity or at law). We
express no opinion as to the availability of equitable remedies. In applying
such equitable principles, a court, among other things, might not allow a
creditor to accelerate the maturity of a debt or enforce a guaranty thereof upon
the occurrence of a default deemed immaterial or for non-credit reasons or might
decline to order a debtor to perform covenants. Such principles applied by a
court might also include a requirement that a creditor act with reasonableness
and in good faith.

              (b) Certain rights, remedies and waivers of the Loan Documents may
be unenforceable in whole or in part, but the inclusion of such provisions does
not affect the validity of the Loan Documents taken as a whole and, except as
set forth in subparagraph (a) above, the Loan Documents taken as a whole contain
adequate provisions for enforcing payment of the Obligations; however, the
unenforceability of such provisions may result in delays in or limitations on
the enforcement of the parties' rights and remedies under the Loan Documents
(and we express no opinion as to the economic consequences, if any, of such
delays or limitations).

              (c) We call your attention to the following matters as to which we
express no opinion:

                     (i) the agreements in the Loan Documents to indemnify the
       Bank Parties against costs or expenses or liability notwithstanding such
       parties' acts of negligence or willful misconduct;

                     (ii) provisions in the Loan Documents for payment or
       reimbursement of costs, fees and expenses or indemnification for claims,
       losses or liabilities to the extent any such provision may be determined
       by a court or other tribunal to be in an unreasonable amount, to
       constitute a penalty or to be contrary to public policy;

                           (Exhibit C-1, Page 4 of 6)
<PAGE>   51

                     (iii) the agreements in the Loan Documents to the
       jurisdiction or venue of a particular court, to the waiver of the right
       to jury trial or to be served with process by service upon a designated
       third party;

                     (iv) any of the waivers or remedies contained in the Loan
       Documents, whether or not any Loan Document deems any such waiver or
       remedy commercially reasonable, if such waivers or remedies are
       determined (1) not to be commercially reasonable under applicable law,
       (2) to conflict with mandatory provisions of applicable law, (3) to be
       taken in a manner determined to be unreasonable or not performed in good
       faith or with fair dealing or with honesty in fact or (4) to be broadly
       or vaguely stated or not to describe the right or duty purportedly waived
       with reasonable specificity;

                     (v) provisions in the Loan Documents which may be construed
       as imposing penalties or forfeitures, late payment charges or an increase
       in interest rate, upon delinquency in payment or the occurrence of a
       default;

                     (vi) any power of attorney granted under the Loan
       Documents;

                     (vii) provisions in the Loan Documents to the effect that
       rights or remedies are not exclusive, that every right or remedy is
       cumulative and may be exercised in addition to any other right or remedy,
       that the election of some particular remedy does not preclude recourse to
       one or more others or that failure to exercise or delay in exercising
       rights or remedies will not operate as a waiver of any such right or
       remedy;

                     (viii) provisions in the Loan Documents which expressly or
       by implication waive or limit the benefits of statutory, regulatory or
       constitutional rights, unless and to the extent the statute, regulation
       or constitution explicitly allow such waiver or other limitation;

                     (ix) the effect of Section 1698 of the California Civil
       Code which, among other matters, provides that a written contract may be
       modified by an oral agreement to the extent such agreement is performed
       by the parties;

                     (x) the effect of Section 1670.5 of the California Civil
       Code which provides that a court may not enforce or may limit the
       application of a

                           (Exhibit C-1, Page 5 of 6)
<PAGE>   52

       contract or portions thereof which it finds as a matter of law to have
       been unconscionable at the time the contract was made; and

                     (xi) the effect of (1) any modification or alteration of
       the Loan Documents or other agreements with Borrower affecting the
       obligations of Borrower, (2) an election of remedies by the Bank
       Parties, or (3) any other action by the Bank Parties that materially
       prejudices any Guarantor Subsidiary if such modification, election or
       action occurs without notice to the Guarantor Subsidiaries and without
       giving the Guarantor Subsidiaries an opportunity to cure any default by
       Borrower.

              Our opinions expressed herein are limited to the laws of the State
of California, the General Corporation Law of the State of Delaware and the
federal laws of the United States, and we do not express any opinion herein
concerning any other law, including, but not limited to, ordinances, regulations
or practices of any county, city or other government agency or body within the
State of California.

              This opinion is being provided for your benefit at the specific
request of our clients, is rendered to you in connection with the transaction
referred to above and may not be relied upon by any person (other than the Bank
Parties, an Eligible Assignee or any successor in interest of any Bank Party) or
by you or the other Bank Parties in any other context. Copies hereof may be
furnished (a) to your independent auditors and attorneys, (b) to any
governmental agency or authority having regulatory jurisdiction over you, (c)
pursuant to an order of legal process of any court or of any governmental agency
or authority, or (d) in connection with any legal action to which you are a
party arising out of the transaction referred to above. This opinion is rendered
as of the date hereof and we hereby disclaim any obligation to advise any person
entitled to rely hereon of any change in the matters stated herein.

                                   Very truly yours,

                        FORM OF BARTON P. PACHINO OPINION

                                  May 10, 2000

To:    Bank of America, N.A.,
       as Administrative Agent
       5 Park Plaza, Suite 500
       Irvine, California  92614

       The Banks Party to the Loan Agreement Referred to Below

Ladies and Gentlemen:

              I am the Senior Vice President and General Counsel of Kaufman and
Broad Home Corporation, a Delaware corporation ("KBHC"). KBHC shall also be
referred to herein as the "Borrower". I have acted as such in connection with
the 2000 Bridge Loan Agreement dated as of May 10, 2000 (the "Agreement"), by
and among the Borrower, the Banks which are the parties thereto, Bank of
America, N.A., as Administrative Agent, and Banc of America Securities LLC, as
Lead Arranger and Sole Book Manager.

              This opinion is furnished to you pursuant to Section 8.1(a)(v) of
the Agreement. Terms not otherwise defined herein shall have the meanings
defined for such terms in the Agreement. The term "Loan Documents", as used
herein, means those Loan Documents (as defined in the Agreement) in existence as
of the Closing Date, including without limitation those referenced in paragraphs
(a) through (c) below.

              This opinion is rendered to you as a supplement to the legal
opinion of Munger, Tolles & Olson LLP of even date herewith in connection with
the Agreement but expressly does not incorporate the terms of said opinion.

              For purposes of this opinion, I have examined originals, or copies
identified to my satisfaction as being true copies, of the following documents:

                           (Exhibit C-2, Page 1 of 8)
<PAGE>   54

                      a.     The Agreement;
                      b.     The Notes under the Agreement; and
                      c.     The Subsidiary Guaranty.

              I have also made such investigations of fact and law, obtained
such certificates of Responsible Officials of Borrower and certain of its
Subsidiaries and of public officials, reviewed incorporation and partnership
documentation, resolutions, secretary's certificates, good standing certificates
and other documents as appropriate of and for the Borrower and the Guarantor
Subsidiaries, as applicable, and done such other things as I have deemed
necessary for the purpose of this opinion.

              I have assumed (i) all natural persons have legal capacity, (ii)
the genuineness of all signatures of all parties other than Borrower and the
Guarantor Subsidiaries listed in Schedule 4.4 to the Agreement, (iii) the
conformity to authentic original documents of all documents submitted to me as
copies and the authenticity of all documents submitted to me as originals, (iv)
as to all parties other than Borrower and the Guarantor Subsidiaries, the due
authorization, execution and delivery of all documents and the validity and
enforceability thereof against all parties thereto other than Borrower and the
Guarantor Subsidiaries, (v) that each Person (other than Borrower and the
Guarantor Subsidiaries) which is a party to the Loan Documents has full power,
authority and legal right, under its charter and other governing documents and
laws applicable to it to perform its respective obligations thereunder, (vi) all
parties to any Loan Documents have filed all required franchise tax returns, if
any, and paid all required taxes, if any, under the California Revenue &
Taxation Code and under the laws of the State of Delaware and the respective
states of incorporation or formation of the Guarantor Subsidiaries, (vii) that
each of the Banks has the requisite power and authority, has obtained all
necessary consents, licenses and permits, has taken all necessary action and has
complied with any and all applicable laws with which such Bank is required to
comply, in each case relating to or affecting the matters and actions
contemplated by the Loan Documents, (viii) that each of the Banks is a national
bank, state bank or similar financial institution and is an exempt lender under
Article XV of the California Constitution or statutes enacted pursuant thereto
and (ix) that the Loan Documents have not been modified, amended, terminated or
revoked in any respect, and remain in full force and effect as of the date
hereof.

              With respect to those opinions expressed below to be to
"knowledge" or "to the knowledge of the undersigned," or similar such wording, I
am referring solely to my individual, actual knowledge. Except as expressly set
forth herein, I did not undertake a review or examination of the activities or
business records of Borrower or any Subsidiaries specifically for the purpose of
rendering this opinion or to determine the existence or absence of such facts.
As Senior Vice President and General Counsel of KBHC, however, material
information respecting the matters covered by such opinions is brought to my
attention on a regular basis as a matter of internal policy and

                           (Exhibit C-2, Page 2 of 8)
<PAGE>   55

I intend the phrase "to the knowledge of the undersigned" to mean that, in
reviewing such information, nothing has come to my attention which caused or
should have caused me not to render such opinions.

              Based upon the foregoing and in reliance thereon, I am of the
opinion that:

              1. KBHC is a corporation duly organized, validly existing and in
good standing under the Laws of the State of Delaware, and its certificate of
incorporation does not provide for the termination of its existence. KBHC is
duly qualified or registered to transact business and is in good standing as a
foreign corporation in the State of California and each other jurisdiction in
which the conduct of its business or the ownership of its Properties makes such
qualifications or registration necessary, except where the failure so to qualify
or register and to be in good standing would not constitute a Material Adverse
Effect.

              2. Borrower has all requisite corporate power and authority to
conduct its business, to own and lease its Properties and to execute, deliver
and perform all of its Obligations under the Loan Documents to which it is a
Party.

              3. To the knowledge of the undersigned, Borrower is in substantial
compliance with all Laws and other legal requirements applicable to its
business, has obtained all authorizations, consents, approvals, orders, licenses
and permits from, and has accomplished all filings, registrations and
qualifications with, or obtained exemptions from any of the foregoing from, any
Government Agency that are necessary for the transaction of its business, except
where the failure so to comply, file, register, qualify or obtain exemptions
would not constitute a Material Adverse Effect.

              4. The execution, delivery and performance by Borrower and by each
Guarantor Subsidiary of each of the Loan Documents to which it is a Party have
been duly authorized by all necessary corporate action, and do not:

                     a. require under the charter documents of Borrower or any
              Guarantor Subsidiary any consent or approval not heretofore
              obtained of any partner, director, stockholder, security holder or
              creditor of such Party;

                     b. violate or conflict with the Party's charter,
              certificate or articles of incorporation or bylaws;

                     c. to the knowledge of the undersigned, result in or
              require the creation or imposition of any Lien or Right of Others
              (other than as

                           (Exhibit C-2, Page 3 of 8)
<PAGE>   56

              provided under the Loan Documents) upon or with respect to any
              Property now owned or leased by such Party;

                     d. violate any Requirement of Law known to the undersigned
              to be applicable to such Party; or

                     e. result in a breach of or constitute a default under, or
              cause or permit the acceleration of any obligation owed under, any
              indenture or loan or credit agreement known to the undersigned or
              any other Contractual Obligation known to the undersigned to which
              such Party is a party or by which such Party or any of its
              Property is bound or affected;

and, to the knowledge of the undersigned, neither Borrower nor any Subsidiary of
Borrower is in violation of, or default under, any Requirement of Law or
contractual obligation, or any indenture, loan or credit agreement described in
subparagraph (e) above in any respect that would constitute a Material Adverse
Effect.

              5. Each of the Loan Documents to which either Borrower or any
Guarantor Subsidiary is a Party will, when executed and delivered by Borrower or
such Guarantor Subsidiary, as the case may be, constitute the legal, valid and
binding obligation of Borrower or such Guarantor Subsidiary, as the case may be,
enforceable against such Borrower or such Guarantor Subsidiary, as the case may
be, in accordance with its terms.

              6. Except as have heretofore been obtained, no authorization,
consent, approval, order, license or permit from, or filing, registration or
qualification with, or exemption from any of the foregoing from, any
Governmental Agency under any Requirement of Law imposed on Borrower or any
Guarantor Subsidiary by the laws of the United States of America or the State of
California, in each case as the same exists on the date hereof, is or will be
required to authorize or permit the execution, delivery and performance by
Borrower or by any Significant Subsidiary of the Loan Documents to which it is a
Party.

              7. Each Significant Subsidiary which is a Domestic Subsidiary is a
legal entity of the form described for that Subsidiary in Schedule 4.4 to the
Agreement, duly organized, validly existing and in good standing under the Laws
of its jurisdiction of formation, is duly qualified or registered to do business
as a foreign organization (if applicable) and is in good standing as such in
each jurisdiction in which the conduct of its business or the ownership or
leasing of its Properties makes such qualifications or registration necessary
(except where the failure to be so qualified or registered and in good standing
does not constitute a Material Adverse Effect) and has all requisite power and
authority to conduct its business and to own and lease its Properties and to

                           (Exhibit C-2, Page 4 of 8)
<PAGE>   57

execute, deliver and perform the obligations under the Loan Documents to which
it is a Party.

              8. To the knowledge of the undersigned, each Significant
Subsidiary is in substantial compliance with all Laws and other requirements
applicable to its business, has obtained all authorizations, consents,
approvals, orders, licenses and permits from, and has accomplished all filings,
registrations and qualifications with, or obtained exemptions from any of the
foregoing from, any Governmental Agency that are necessary for the transaction
of its business, except where the failure so to comply, file, register, qualify
or obtain exemptions does not constitute a Material Adverse Effect.

              9. Neither Borrower nor any of its Subsidiaries is subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940.

              10. To the knowledge of the undersigned, there are no actions,
suits or proceedings pending or threatened against or affecting Borrower or any
of its Subsidiaries or any Property of any of them in any court of Law or before
any Governmental Agency in which there is a reasonable probability of a decision
which would constitute a Material Adverse Effect.

              11. Neither Borrower nor any of its Subsidiaries is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of "purchasing" or "carrying" any "margin stock" or
"margin security" within the meanings of Regulation U of the Board of Governors
of the Federal Reserve System and no loan under the Agreement will be used to
purchase or carry any such margin stock in violation of Regulation U.

              12. To the knowledge of the undersigned, Borrower and its
Subsidiaries are in substantial compliance with all applicable Laws relating to
environmental protection where the failure to comply would constitute a Material
Adverse Effect, and have not received any notice from any Governmental Agency
respecting the alleged violation by Borrower or any Subsidiary of such Laws
which would constitute a Material Adverse Effect which has not been or is not
being corrected.

              In addition to any assumptions, qualifications and other matters
set forth elsewhere herein, the opinions set forth above are subject to the
following:

                     a. My opinion with respect to the legality, validity,
              binding effect and enforceability of any Loan Document, agreement
              or provision is subject to the effect of any applicable
              bankruptcy, insolvency,

                           (Exhibit C-2, Page 5 of 8)
<PAGE>   58

              fraudulent conveyance, fraudulent transfer and equitable
              subordination, reorganization, moratorium or similar law affecting
              creditors' rights generally and to the effect of general
              principles of equity, including (without limitation) concepts of
              materiality, reasonableness, estoppel, good faith and fair dealing
              (regardless of whether considered in a proceeding in equity or at
              law). I express no opinion as to the availability of equitable
              remedies. In applying such equitable principles, a court, among
              other things, might not allow a creditor to accelerate the
              maturity of a debt or enforce a guaranty thereof upon the
              occurrence of a default deemed immaterial or for non-credit
              reasons or might decline to order a debtor to perform covenants.
              Such principles applied by a court might also include a
              requirement that a creditor act with reasonableness and in good
              faith.

                     b. Certain rights, remedies and waivers of the Loan
              Documents may be unenforceable in whole or in part, but the
              inclusion of such provisions does not affect the validity of the
              Loan Documents taken as a whole and, except as set forth in
              subparagraph (a) above, the Loan Documents taken as a whole
              contain adequate provisions for enforcing payment of the
              "Obligations" (as defined in the Agreement); however, the
              unenforceability of such provisions may result in delays in or
              limitations on the enforcement of the parties' rights and remedies
              under the Loan Documents and I express no opinion as to the
              economic consequences, if any, of such delays or limitations.

                     c. I call your attention to the following matters as to
              which I express no opinion:

                            (i) the agreements in the Loan Documents to
              indemnify you against costs or expenses or liability
              notwithstanding your acts of negligence or willful misconduct;

                            (ii) provisions in the Loan Documents for payment or
              reimbursement of costs, fees and expenses or indemnification for
              claims, losses or liabilities to the extent any such provision may
              be determined by a court or other tribunal to be in an
              unreasonable amount, to constitute a penalty or to be contrary to
              public policy;

                            (iii) the agreements in the Loan Documents to the
              jurisdiction or venue of a particular court, to the waiver of the
              right to jury trial or to be served with process by service upon a
              designated third party;

                           (Exhibit C-2, Page 6 of 8)
<PAGE>   59

                            (iv) any of the waivers or remedies contained in the
              Loan Documents, whether or not any Loan Document deems any such
              waiver or remedy commercially reasonable, if such waivers or
              remedies are determined (1) not to be commercially reasonable
              under applicable law, (2) to conflict with mandatory provisions of
              applicable law, (3) to be taken in a manner determined to be
              unreasonable or not performed in good faith or with fair dealing
              or with honesty in fact or (4) to be broadly or vaguely stated or
              not to describe the right or duty purportedly waived with
              reasonable specificity;

                            (v) provisions in the Loan Documents which may be
              construed as imposing penalties or forfeitures, late payment
              charges or an increase in interest rate, upon delinquency in
              payment or the occurrence of a default;

                            (vi) any power of attorney granted under the Loan
              Documents;

                            (vii) provisions in the Loan Documents to the effect
              that rights or remedies are not exclusive, that every right or
              remedy is cumulative and may be exercised in addition to any other
              right or remedy, that the election of some particular remedy does
              not preclude recourse to one or more others or that failure to
              exercise or delay in exercising rights or remedies will not
              operate as a waiver of any such right or remedy;

                            (viii) provisions in the Loan Documents which
              expressly or by implication waive or limit the benefits of
              statutory, regulatory or constitutional rights, unless and to the
              extent the statute, regulation or constitution explicitly allow
              such waiver or other limitation;{ and}

                            (ix) the effect of Section 1698 of the California
              Civil Code which, among other matters, provides that a written
              contract may be modified by an oral agreement to the extent such
              agreement is performed by the parties;

                            (x) effect of Section 1670.5 of the California Civil
              Code which provides that a court may not enforce or may limit the
              application of a contract or portions thereof which it finds as a
              matter of law to have been unconscionable at the time the contract
              was made; and

                            (xi) the effect of (1) any modification or
              alteration of the Loan Documents or other agreements with Borrower
              affecting the

                           (Exhibit C-2, Page 7 of 8)
<PAGE>   60

              obligations of Borrower, (2) an election of remedies by the Bank
              Parties, or (3) any other action by the Bank Parties that
              materially prejudices any Guarantor Subsidiary if such
              modification, election or action occurs without notice to the
              Guarantor Subsidiaries and without giving the Guarantor
              Subsidiaries an opportunity to cure any default by Borrower.

              My opinion expressed herein is limited to the laws of the State of
California, the General Corporation Law of the State of Delaware and the federal
laws of the United States, and I do not express any opinion herein concerning
any other law, including, but not limited to, ordinances, regulations, or
practices of any county, city or other government agency or body within the
State of California.

              This opinion is being rendered to you in connection with the
transaction referred to above and may not be relied upon by any person (other
than the Banks, an Eligible Assignee or any successor in interest of any Bank)
or by you or the other Banks in any other context. Copies hereof may be
furnished (a) to your independent auditors and attorneys, (b) to any
governmental agency or authority having regulatory jurisdiction over you, (c)
pursuant to order of legal process of any court or of any governmental agency or
authority or (d) in connection with any legal action to which you are a party
arising out of the transaction referred to above. This opinion is rendered as of
the date hereof and I hereby disclaim any obligation to advise any person
entitled to rely hereon of any change in the matters stated herein.

                                   Very truly yours,

                                   Barton P. Pachino

BORROWER:      KAUFMAN AND BROAD HOME CORPORATION,
               a Delaware corporation

GUARANTORS:    See Schedule 1 hereto

TO:     BANK OF AMERICA, N.A., for itself and as Administrative Agent

                               SUBSIDIARY GUARANTY

              THIS GUARANTY ("Guaranty") dated as of May 10, 2000, is made by
each of the parties listed on Schedule 1 hereto, together with each other person
who may become a party hereto pursuant to Section 10 of this Guaranty (each, a
Guarantor and collectively, "Guarantors"), jointly and severally, in favor of
Bank of America, N.A., formerly known as Bank of America National Trust and
Savings Association, and the Banks (as those terms are defined in the
below-referenced Loan Agreement), with reference to the following facts:

                                    RECITALS

              A. Pursuant to the 2000 Bridge Loan Agreement of even date
herewith entered into by and among Kaufman and Broad Home Corporation, a
Delaware corporation ("Borrower"), the Banks signatory thereto, Bank of America,
N.A., formerly known as Bank of America National Trust and Savings Association,
as Administrative Agent and Banc of America Securities LLC, as Lead Arranger and
Sole Book Manager (as the same may be amended from time to time, the "Loan
Agreement"), the Banks are making a credit facility available to Borrower.

              B. As a condition of the availability of such credit facility,
Guarantors are required to enter into this Guaranty.

              C. Guarantors expect to realize direct and indirect benefits as
the result of the availability of the aforementioned credit facility, and as the
result of the execution of this Guaranty.

                                    AGREEMENT

              NOW, THEREFORE, in order to induce the Banks to extend the
aforementioned credit facility, and for other good and valuable consideration,
the receipt and adequacy of which is hereby acknowledged, each Guarantor hereby
represents, warrants, covenants, agrees and guaranties as follows:

                                      -1-
<PAGE>   62

              (1) Terms used in this Guaranty but not defined herein shall have
the meanings defined for them in the Loan Agreement.

              (2) Guarantors unconditionally guarantee and promise to pay to
Bank of America, N.A., formerly known as Bank of America National Trust and
Savings Association, as the Administrative Agent for the Banks, on demand, in
lawful money of the United States, any and all Indebtedness of Borrower then due
to the Banks. The word "Indebtedness" means any and all advances, debts,
obligations and liabilities of Borrower heretofore, now, or hereafter made,
incurred or created under the Loan Agreement and under the Loan Documents, and
whether Borrower may be liable individually or jointly with others, or whether
such Indebtedness may be or hereafter becomes otherwise unenforceable.

              (3) This Guaranty is irrevocable in nature, is a guaranty of
prompt and punctual payment and performance of all Indebtedness of Borrower, and
is not merely a guaranty of collection. The Indebtedness guaranteed hereunder
includes that arising under successive transactions which shall either continue
the Indebtedness from time to time or renew it after it has been satisfied.
Anything in this Guaranty to the contrary notwithstanding, the maximum liability
of any Guarantor hereunder shall be limited to the extent required for the
obligation of such Guarantor to be valid, binding and enforceable and not
otherwise voidable or avoidable.

              (4) The obligations hereunder are joint and several, and
independent of the obligations of Borrower and or any of its other Subsidiaries.
Separate action or actions may be brought and prosecuted against any Guarantor
whether action is brought against any Borrower or any of its other Subsidiaries,
including any other Guarantor, or whether Borrower or any of its other
Subsidiaries, including any other Guarantor, may be joined in any such action or
actions.

              (5) Each Guarantor authorizes the Banks, without notice or demand
and without affecting its liability hereunder, from time to time to (a) renew,
compromise, extend, accelerate or otherwise change the time for payment of, or
otherwise change the terms of the Indebtedness or any part thereof, including
increase or decrease of the rate of interest thereon; (b) take and hold security
for the payment of this Guaranty or the Indebtedness guaranteed, and exchange,
enforce, waive and release any such security; (c) apply such security and direct
the order or manner of sale thereof as the Administrative Agent or any Bank in
its discretion may determine; and (d) release or substitute any one or more of
the endorsers or guarantors.

              (6) Each Guarantor waives, to the fullest extent permitted by
applicable law, any right to require any Bank to (a) proceed against Borrower or
any of its other Subsidiaries, including any other Guarantor; (b) proceed
against or exhaust any security held from Borrower or any of its Subsidiaries;
or (c) pursue any other remedy in the Banks' power whatsoever. Each Guarantor
waives any defense arising by reason of any disability or other defense of
Borrower or by reason of the cessation from any cause whatsoever of the
liability of Borrower, other than payment in full of the Indebtedness. Until all
Indebtedness of Borrower to the Banks shall have been paid in full, each
Guarantor waives any right to enforce any

                                      -2-
<PAGE>   63

remedy which the Banks now have or may hereafter have against Borrower or any of
its other Subsidiaries, and waives any benefit of, and any right to participate
in, any security now or hereafter held by the Banks. Guarantors waive all rights
and defenses arising out of an election of remedies by the creditor, even though
that election of remedies, such as a nonjudicial foreclosure with respect to
security for a guaranteed obligation, has destroyed the guarantor's rights of
subrogation and reimbursement against the principal by the operation of Section
580d of the Code of Civil Procedure or otherwise. Guarantors expressly waive to
the fullest extent permitted by applicable Law all other suretyship defenses
they otherwise might or would have under any Law. Each Guarantor waives any
right of subrogation that it may have in respect to the obligations of Borrower
to the Banks. Each Guarantor waives all presentments, demands for performance,
notices of nonperformance, protests, notices of protest, notices of dishonor,
and notices of acceptance of this Guaranty and of the existence, creation, or
incurring of new or additional Indebtedness.

              (7) After demand upon the Guarantors for payment under this
Guaranty, each Guarantor hereby specifically authorizes each Bank (subject to
the approval of the Majority Banks) in which such Guarantor maintains a deposit
account (whether a general or special deposit account, other than trust
accounts) or a certificate of deposit to setoff any Obligations owed to the
Banks against such deposit account or certificate of deposit without prior
notice to any Guarantor (which notice is hereby waived) whether or not such
deposit account or certificate of deposit has then matured. Nothing in this
paragraph shall limit or restrict the exercise by a Bank of any right to setoff
or banker's lien under applicable Law, subject to the approval of the Majority
Banks.

              (8) Each Guarantor represents and warrants to the Banks that it
has established adequate means of obtaining from Borrower and its Subsidiaries,
on a continuing basis, financial and other information pertaining to the
businesses, operations and condition (financial and otherwise) of Borrower and
its Subsidiaries, and that Guarantor now is and hereafter will be completely
familiar with the businesses, operations and condition (financial and otherwise)
of Borrower and its Subsidiaries. Each Guarantor hereby expressly waives and
relinquishes any duty on the part of the Banks (should any such duty exist) to
disclose to any Guarantor any matter, fact or thing related to the businesses,
operations or condition (financial or otherwise) of Borrower or its
Subsidiaries, whether now known or hereafter known by the Banks during the life
of this Guaranty.

              (9) Guarantors agree to pay, within thirty (30) days after demand,
the reasonable out-of-pocket costs and expenses of the Administrative Agent and
each of the Banks in connection with the enforcement of this Guaranty, including
without limitation the reasonable fees and out-of-pocket expenses of any legal
counsel retained by the Administrative Agent or any of the Banks.

              (10) Any other Person may become a Guarantor under, and become
bound by the terms and conditions of, this Guaranty by executing and delivering
to the Administrative Agent an Instrument of Joinder substantially in the form
attached hereto as Exhibit A.

                                      -3-
<PAGE>   64

              (11) This Guaranty shall be governed by and construed according to
the laws of the State of California, to the jurisdiction of which the parties
hereto submit.

                                   EXECUTION

BORROWER:      KAUFMAN AND BROAD HOME CORPORATION,
               a Delaware corporation

GUARANTORS:    See Schedule 1 hereto

TO:     BANK OF AMERICA, N.A., for itself and as Administrative Agent

                               SUBSIDIARY GUARANTY

               THIS GUARANTY ("Guaranty") dated as of May 10, 2000, is made by
each of the parties listed on Schedule 1 hereto, together with each other person
who may become a party hereto pursuant to Section 10 of this Guaranty (each, a
Guarantor and collectively, "Guarantors"), jointly and severally, in favor of
Bank of America, N.A., formerly known as Bank of America National Trust and
Savings Association, and the Banks (as those terms are defined in the
below-referenced Loan Agreement), with reference to the following facts:

                                    RECITALS

               A. Pursuant to the 2000 Bridge Loan Agreement of even date
herewith entered into by and among Kaufman and Broad Home Corporation, a
Delaware corporation ("Borrower"), the Banks signatory thereto, Bank of America,
N.A., formerly known as Bank of America National Trust and Savings Association,
as Administrative Agent and Banc of America Securities LLC, as Lead Arranger and
Sole Book Manager (as the same may be amended from time to time, the "Loan
Agreement"), the Banks are making a credit facility available to Borrower.

               B. As a condition of the availability of such credit facility,
Guarantors are required to enter into this Guaranty.

               C. Guarantors expect to realize direct and indirect benefits as
the result of the availability of the aforementioned credit facility, and as the
result of the execution of this Guaranty.

                                    AGREEMENT

               NOW, THEREFORE, in order to induce the Banks to extend the
aforementioned credit facility, and for other good and valuable consideration,
the receipt and adequacy of which is hereby acknowledged, each Guarantor hereby
represents, warrants, covenants, agrees and guaranties as follows:

                                      -1-
<PAGE>   85

               (1) Terms used in this Guaranty but not defined herein shall have
the meanings defined for them in the Loan Agreement.

               (2) Guarantors unconditionally guarantee and promise to pay to
Bank of America, N.A., formerly known as Bank of America National Trust and
Savings Association, as the Administrative Agent for the Banks, on demand, in
lawful money of the United States, any and all Indebtedness of Borrower then due
to the Banks. The word "Indebtedness" means any and all advances, debts,
obligations and liabilities of Borrower heretofore, now, or hereafter made,
incurred or created under the Loan Agreement and under the Loan Documents, and
whether Borrower may be liable individually or jointly with others, or whether
such Indebtedness may be or hereafter becomes otherwise unenforceable.

               (3) This Guaranty is irrevocable in nature, is a guaranty of
prompt and punctual payment and performance of all Indebtedness of Borrower, and
is not merely a guaranty of collection. The Indebtedness guaranteed hereunder
includes that arising under successive transactions which shall either continue
the Indebtedness from time to time or renew it after it has been satisfied.
Anything in this Guaranty to the contrary notwithstanding, the maximum liability
of any Guarantor hereunder shall be limited to the extent required for the
obligation of such Guarantor to be valid, binding and enforceable and not
otherwise voidable or avoidable.

               (4) The obligations hereunder are joint and several, and
independent of the obligations of Borrower and or any of its other Subsidiaries.
Separate action or actions may be brought and prosecuted against any Guarantor
whether action is brought against any Borrower or any of its other Subsidiaries,
including any other Guarantor, or whether Borrower or any of its other
Subsidiaries, including any other Guarantor, may be joined in any such action or
actions.

               (5) Each Guarantor authorizes the Banks, without notice or demand
and without affecting its liability hereunder, from time to time to (a) renew,
compromise, extend, accelerate or otherwise change the time for payment of, or
otherwise change the terms of the Indebtedness or any part thereof, including
increase or decrease of the rate of interest thereon; (b) take and hold security
for the payment of this Guaranty or the Indebtedness guaranteed, and exchange,
enforce, waive and release any such security; (c) apply such security and direct
the order or manner of sale thereof as the Administrative Agent or any Bank in
its discretion may determine; and (d) release or substitute any one or more of
the endorsers or guarantors.

               (6) Each Guarantor waives, to the fullest extent permitted by
applicable law, any right to require any Bank to (a) proceed against Borrower or
any of its other Subsidiaries, including any other Guarantor; (b) proceed
against or exhaust any security held from Borrower or any of its Subsidiaries;
or (c) pursue any other remedy in the Banks' power whatsoever. Each Guarantor
waives any defense arising by reason of any disability or other defense of
Borrower or by reason of the cessation from any cause whatsoever of the
liability of Borrower, other than payment in full of the Indebtedness. Until all
Indebtedness of Borrower to the Banks shall have been paid in full, each
Guarantor waives any right to enforce any

                                      -2-
<PAGE>   86

remedy which the Banks now have or may hereafter have against Borrower or any
of its other Subsidiaries, and waives any benefit of, and any right to
participate in, any security now or hereafter held by the Banks. Guarantors
waive all rights and defenses arising out of an election of remedies by the
creditor, even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for a guaranteed obligation, has destroyed
the guarantor's rights of subrogation and reimbursement against the principal by
the operation of Section 580d of the Code of Civil Procedure or otherwise.
Guarantors expressly waive to the fullest extent permitted by applicable Law all
other suretyship defenses they otherwise might or would have under any Law. Each
Guarantor waives any right of subrogation that it may have in respect to the
obligations of Borrower to the Banks. Each Guarantor waives all presentments,
demands for performance, notices of nonperformance, protests, notices of
protest, notices of dishonor, and notices of acceptance of this Guaranty and of
the existence, creation, or incurring of new or additional Indebtedness.

               (7) After demand upon the Guarantors for payment under this
Guaranty, each Guarantor hereby specifically authorizes each Bank (subject to
the approval of the Majority Banks) in which such Guarantor maintains a deposit
account (whether a general or special deposit account, other than trust
accounts) or a certificate of deposit to setoff any Obligations owed to the
Banks against such deposit account or certificate of deposit without prior
notice to any Guarantor (which notice is hereby waived) whether or not such
deposit account or certificate of deposit has then matured. Nothing in this
paragraph shall limit or restrict the exercise by a Bank of any right to setoff
or banker's lien under applicable Law, subject to the approval of the Majority
Banks.

               (8) Each Guarantor represents and warrants to the Banks that it
has established adequate means of obtaining from Borrower and its Subsidiaries,
on a continuing basis, financial and other information pertaining to the
businesses, operations and condition (financial and otherwise) of Borrower and
its Subsidiaries, and that Guarantor now is and hereafter will be completely
familiar with the businesses, operations and condition (financial and otherwise)
of Borrower and its Subsidiaries. Each Guarantor hereby expressly waives and
relinquishes any duty on the part of the Banks (should any such duty exist) to
disclose to any Guarantor any matter, fact or thing related to the businesses,
operations or condition (financial or otherwise) of Borrower or its
Subsidiaries, whether now known or hereafter known by the Banks during the life
of this Guaranty.

               (9) Guarantors agree to pay, within thirty (30) days after
demand, the reasonable out-of-pocket costs and expenses of the Administrative
Agent and each of the Banks in connection with the enforcement of this Guaranty,
including without limitation the reasonable fees and out-of-pocket expenses of
any legal counsel retained by the Administrative Agent or any of the Banks.

               (10) Any other Person may become a Guarantor under, and become
bound by the terms and conditions of, this Guaranty by executing and delivering
to the Administrative Agent an Instrument of Joinder substantially in the form
attached hereto as Exhibit A.

                                      -3-
<PAGE>   87

               (11) This Guaranty shall be governed by and construed according
to the laws of the State of California, to the jurisdiction of which the parties
hereto submit.

To:  Bank of America, N.A.,
       as Administrative Agent

     The Banks Party to the Loan Agreement Referred to Below

Ladies and Gentlemen:

          I am the Senior Vice President and General Counsel of Kaufman and
Broad Home Corporation, a Delaware corporation ("KBHC"). KBHC shall also be
referred to herein as the "Borrower". I have acted as such in connection with
the 2000 Bridge Loan Agreement dated as of May 10, 2000 (the "Agreement"), by
and among the Borrower, the Banks which are the parties thereto, Bank of
America, N.A., as Administrative Agent, and Banc of America Securities LLC, as
Lead Arranger and Sole Book Manager.

          This opinion is furnished to you pursuant to Section 8.1(a)(v) of the
Agreement. Terms not otherwise defined herein shall have the meanings defined
for such terms in the Agreement. The term "Loan Documents", as used herein,
means Loan Documents (as defined in the Agreement) in existence as of the
Closing Date, including without limitation those referenced in paragraphs (a)
through (c) below.

          This opinion is rendered to you as a supplement to the legal opinion
of Munger, Tolles & Olson LLP of even date herewith in connection with the
Agreement but expressly does not incorporate the terms of said opinion.

          For purposes of this opinion, I have examined originals, or copies
identified to my satisfaction as being true copies, of the following documents:

               a.   The Agreement;

               b.   The Notes under the Agreement; and

               c.   The Subsidiary Guaranty.
<PAGE>   95

Bank of America, N.A.
May 10, 2000
Page 2

          I have also made such investigations of fact and law, obtained such
certificates of Responsible Officials of Borrower and certain of its
Subsidiaries and of public officials, reviewed incorporation and partnership
documentation, resolutions, secretary's certificates, good standing
certificates and other documents as appropriate of and for the Borrower and the
Guarantor Subsidiaries, as applicable, and done such other things as I have
deemed necessary for the purpose of this opinion.

          I have assumed (i) all natural persons have legal capacity, (ii) the
genuineness of all signatures of all parties other than Borrower and the
Guarantor Subsidiaries listed in Schedule 4.4 to the Agreement, (iii) the
conformity to authentic original documents of all documents submitted to me as
copies and the authenticity of all documents submitted to me as originals,
(iv) as to all parties other than Borrower and the Guarantor Subsidiaries, the
due authorization, execution and delivery of all documents and the validity and
enforceability thereof against all parties thereto other than Borrower and the
Guarantor Subsidiaries, (v) that each Person (other than Borrower and the
Guarantor Subsidiaries) which is a party to the Loan Documents has full power,
authority and legal right, under its charter and other governing documents and
laws applicable to it to perform its respective obligations thereunder,
(vi) all parties to any Loan Documents have filed all required franchise tax
returns, if any, and paid all required taxes, if any, under the California
Revenue & Taxation Code and under the laws of the State of Delaware and the
respective states of incorporation or formation of the Guarantor Subsidiaries,
(vii) that each of the Banks has the requisite power and authority, has
obtained all necessary consents, licenses and permits, has taken all necessary
action and has complied with any and all applicable laws with which such Bank
is required to comply, in each case relating to or affecting the matters and
actions contemplated by the Loan Documents, (viii) that each of the Banks is a
national bank, state bank or similar financial institution and is an exempt
lender under Article XV of the California Constitution or statutes enacted
pursuant thereto, and (ix) that the Loan Documents have not been modified,
amended, terminated or revoked in any respect, and remain in full force and
effect as of the date hereof.

          With respect to those opinions expressed below to be to "knowledge"
or "to the knowledge of the undersigned," or similar such wording, I am
referring solely to my individual, actual knowledge. Except as expressly set
forth herein, I did not undertake a review or examination of the activities or
business records of Borrower or any Subsidiaries specifically for the purpose
of rendering this opinion or to determine the existence or absence of such
facts. As Senior Vice President and General Counsel of KBHC, however, material
information respecting the matters covered by such opinions is brought to my
attention on a regular basis as a matter of internal policy and I intend the
phrase "to the knowledge of the undersigned" to mean that, in reviewing such
information, nothing has come to my attention which caused or should have
caused me not to render such opinions.

          Based upon the foregoing and in reliance thereon, I am of the opinion
that:

          1.   KBHC is a corporation duly organized, validly existing and in
good standing under the Laws of the State of Delaware, and its certificate of
incorporation does not provide for the termination of its existence. KBHC is
duly qualified or registered to transact business and is in good standing as a
foreign corporation in the State of California and each other
<PAGE>   96

Bank of America, N.A.

Page 3

jurisdiction in which the conduct of its business or the ownership of its
Properties makes such qualifications or registration necessary, except where
the failure so to qualify or register and to be in good standing would not
constitute a Material Adverse Effect.

          2.   Borrower has all requisite corporate power and authority to
conduct its business, to own and lease its Properties and to execute, deliver
and perform all of its Obligations under the Loan Documents to which it is a
Party.

          3.   To the knowledge of the undersigned, Borrower is in substantial
compliance with all Laws and other legal requirements applicable to its
business, has obtained all authorizations, consents, approvals, orders,
licenses and permits from, and has accomplished all filings, registrations and
qualifications with, or obtained exemptions from any of the foregoing from, any
Government Agency that are necessary for the transaction of its business,
except where the failure so to comply, file, register, qualify or obtain
exemptions would not constitute a Material Adverse Effect.

          4.   The execution, delivery and performance by Borrower and by each
Guarantor Subsidiary of each of the Loan Documents to which it is a Party have
been duly authorized by all necessary corporate action, and do no:

               a.   require under the charter documents of Borrower or any
          Guarantor Subsidiary any consent or approval not heretofore obtained
          of any partner, director, stockholder, security holder or creditor
          of such Party;

               b.   violate or conflict with the Party's charter, certificate or
          articles of incorporation or bylaws;

               c.   to the knowledge of the undersigned, result in or require
          the creation or imposition of any Lien or Right of Others (other
          than as provided under the Loan Documents) upon or with respect to
          any Property now owned or leased by such Party;

               d.   violate any Requirements of Law known to the undersigned
          to be applicable to such Party; or

               e.   result in a breach of or constitute a default under, or
          cause or permit the acceleration of any obligation owed under, any
          indenture or loan or credit agreement known to the undersigned or
          any other Contractual Obligation known to the undersigned to which
          such Party is a party or by which such Party or any of its Property
          is bound or affected;

and, to the knowledge of the undersigned, neither Borrower nor any Subsidiary
of Borrower is in violation of, or default under, any Requirement of Law or
contractual obligation, or any indenture, loan or credit agreement described in
subparagraph (e) above in any respect that would constitute a Material Adverse
Effect.

          5.   Each of the Loan Documents to which either Borrower or any
Guarantor Subsidiary is a Party will, when executed and delivered by Borrower
or such Guarantor Subsidiary, as the case may be, constitute the legal, valid
and binding obligation of Borrower or such Guarantor Subsidiary, as the case
may be, enforceable against such Borrower or such Guarantor Subsidiary, as the
case may be, in accordance with its terms.

          6.   Except as have heretofore been obtained, no authorization,
consent, approval, order, license or permit from, or filing, registration or
qualification with, or exemption from any of the foregoing from, any
Governmental Agency under any Requirement of Law imposed on Borrower or any
Guarantor Subsidiary by the laws of the United States of America or the State
of California, in each case as the same exists on the date hereof, is or will
be required to authorize or permit the execution, delivery and performance by
Borrower or by any Significant Subsidiary of the Loan Documents to which it is
a Party.

          7.   Each Significant Subsidiary which is a Domestic Subsidiary is a
legal entity of the form described for that Subsidiary in Schedule 4.4 to the
Agreement, duly organized, validly existing and in good standing under the Laws
of its jurisdiction of formation, is duly qualified or registered to do
business as a foreign organization (if applicable) and is in good standing as
such in each jurisdiction in which the conduct of its business or the ownership
or leasing of its Properties makes such qualifications or registration
necessary (except where the failure to be so qualified or registered and in
good standing does not constitute a Material Adverse Effect) and has all
requisite power and authority to conduct its business and to own and lease its
Properties and to execute, deliver and perform the obligations under the Loan
Documents to which it is a Party.

          8.   To the knowledge of the undersigned, each Significant Subsidiary
is in substantial compliance with all Laws and other requirements applicable to
its business, has obtained all authorizations, consents, approvals, orders,
licenses and permits from, and has accomplished all filings, registrations and
qualifications with, or obtained exemptions from any of the foregoing from, any
Governmental Agency that are necessary for the transactions of its business,
except where the failure so to comply, file, register, qualify or obtain
exemptions does not constitute a Material Adverse Effect.

          9.   Neither Borrower nor any of its Subsidiaries is subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940.

          10.  To the knowledge of the undersigned, there are no actions, suits
or proceedings pending or threatened against or affecting Borrower or any of
its Subsidiaries or any Property of any of them in any court of Law or before
any Governmental Agency in which there is a reasonable probability of a
decision which would constitute a Material Adverse Effect.

          11.  Neither Borrower nor any of its Subsidiaries is engaged
principally, or as one of its important activities, in the business of
extending credit for the purpose of "purchasing" or "carrying" any "margin
stock" or "margin security" within the meanings of Regulation U of
<PAGE>   98

Bank of America, N.A.
May 10, 2000
Page 5

the Board of Governors of the Federal Reserve System and no loan under the
Agreement will be used to purchase or carry any such margin stock in violation
of Regulation U.

          12.  To the knowledge of the undersigned, Borrower and its
Subsidiaries are in substantial compliance with all applicable Laws relating to
environmental protection where the failure to comply would constitute a
Material Adverse Effect, and have not received any notice from any Governmental
Agency respecting the alleged violation by Borrower or any Subsidiary of such
Laws which would constitute a Material Adverse Effect which has not been or is
not being corrected.

          In addition to any assumptions, qualifications and other matters set
forth elsewhere herein, the opinions set forth above are subject to the
following:

               a.   My opinion with respect to the legality, validity, binding
          effect and enforceability of any Loan Document, agreement or provision
          is subject to the effect of any applicable bankruptcy, insolvency,
          fraudulent conveyance, fraudulent transfer and equitable
          subordination, reorganization, moratorium or similar law affecting
          creditors' rights generally and to the effect of general principles of
          equity, including (without limitation) concepts of materiality,
          reasonableness, estoppel, good faith and fair dealing (regardless of
          whether considered in a proceeding in equity or at law). I express no
          opinion as to the availability of equitable remedies. In applying such
          equitable principles, a court, among other things, might not allow a
          creditor to accelerate the maturity of a debt or enforce a guaranty
          thereof upon the occurrence of a default deemed immaterial or for
          non-credit reasons or might decline to order a debtor to perform
          covenants. Such principles applied by a court might also include a
          requirements that a creditor act with reasonableness and in good
          faith.

               b.   Certain rights, remedies and waivers of the Loan Documents
          may be unenforceable in whole or in part, but the inclusion of such
          provisions does not affect the validity of the Loan Documents taken as
          a whole and, except as set forth in subparagraph (a) above, the Loan
          Documents taken as a whole contain adequate provisions for enforcing
          payment of the "Obligations" (as defined in the Agreement); however,
          the unenforceability of such provisions may result in delays in or
          limitations on the enforcement of the parties' rights and remedies
          under the Loan Documents and I express no opinion as to the economic
          consequences, if any, of such delays or limitations.

               c.   I call your attention to the following matters as to which
          I express no opinion:

                    (i)  the agreements in the Loan Documents to indemnify you
          against costs or expenses or liability notwithstanding your acts of
          negligence or willful misconduct;
<PAGE>   99

Bank of America, N.A.
May 10, 2000
Page 6

                    (ii)    provisions in the Loan Documents for payment or
          reimbursement of costs, fees and expenses or indemnification for
          claims, losses or liabilities to the extent any such provision may be
          determined by a court or other tribunal to be in an unreasonable
          amount, to constitute a penalty or to be contrary to public policy;

                    (iii)   the agreements in the Loan Documents to the
          jurisdiction or venue of a particular court, to the waiver of the
          right to jury trial or to be served with process by service upon a
          designated third party;

                    (iv)    any of the waivers or remedies contained in the
          Loan Documents, whether or not any Loan Document deems any such waiver
          or remedy commercially reasonable, if such waivers or remedies are
          determined (1) not to be commercially reasonable under applicable law,
          (2) to conflict with mandatory provisions of applicable law, (3) to be
          taken in a manner determined to be unreasonable or not performed in
          good faith or with fair dealing or with honesty in fact or (4) to be
          broadly or vaguely stated or not to describe the right or duty
          purportedly waived with reasonable specificity;

                    (v)     provisions in the Loan Documents which may be
          construed as imposing penalties or forfeitures, late payment charges
          or an increase in interest rate, upon delinquency in payment or the
          occurrence of a default;

                    (vi)    any power of attorney granted under the Loan
          Documents;

                    (vii)   provisions in the Loan Documents to the effect that
          rights or remedies are not exclusive, that every right or remedy is
          cumulative and may be exercised in addition to any other right or
          remedy, that the election of some particular remedy does not preclude
          recourse to one or more others or that failure to exercise or delay in
          exercising rights or remedies will not operate as a waiver of any such
          right or remedy;

                    (viii)  provisions in the Loan Documents which expressly or
          by implication waive or limit the benefits of statutory, regulatory or
          constitutional rights, unless and to the extent the statute,
          regulation or constitution explicitly allow such waiver or other
          limitation;

                     (ix)   the effect of Section 1698 of the California Civil
          Code which, among other matters, provides that a written contract may
          be modified by an oral agreement to the extent such agreement is
          performed by the parties;

                    (x)     effect of Section 1670.5 of the California Civil
          Code which provides that a court may not enforce or may limit the
          application of a contract or portions thereof which it finds as a
          matter of law to have been unconscionable at the time the contract was
          made; and

                    (xi)    the effect of (1) any modification or alteration of
          the Loan Documents or other agreements with Borrower affecting the
          obligations of Borrower, (2) an election of remedies by the Bank
          Parties, or (3) any other action by the Bank Parties that materially
          prejudices any Guarantor Subsidiary if such modification, election or
          action occurs without notice to the Guarantor Subsidiaries and without
          giving the Guarantor Subsidiaries an opportunity to cure any default
          by Borrower.

To: Bank of America, N.A.
    as Administrative Agent

The Banks Party to the Loan Agreement
  Referred to Below

               Re:    Kaufman and Broad Home Corporation
               -----------------------------------------

Ladies and Gentlemen:

               We have acted as counsel to Kaufman and Broad Home Corporation, a
Delaware corporation ("Borrower"), in connection with the 2000 Bridge Loan
Agreement (the "Loan Agreement") dated as of May 10, 2000, by and among
Borrower; the Banks which are parties thereto; Bank of America, N.A., as
Administrative Agent; Banc of America Securities LLC as Lead Arranger and Sole
Book Manager (the "Arranger") (all such parties other than the Borrower are
collectively referred to herein as "Bank Parties").

               This opinion is furnished to you pursuant to Section 8.1(a)(v) of
the Loan Agreement. Terms not otherwise defined herein shall have the meanings
defined for such terms in the Loan Agreement.

               For the purposes of this opinion, we have examined originals, or
copies identified to our satisfaction as being true copies, of the following
documents:

               (a)    The Loan Agreement;

               (b)    The Notes of even date herewith; and
<PAGE>   102

Bank of America, N.A.
May 10, 2000
Page 2

               (c)    The Subsidiary Guaranty.

               The documents described in (a) through (c) above are sometimes
referred to herein as the "Loan Documents".

               We have also examined such other corporate documents and records,
and other certificates, opinions and instruments and have conducted such
investigations as we have deemed necessary as a basis for the opinions expressed
below. As to factual matters relevant to our opinions expressed below, we have,
without independent investigation, relied upon certificates of public officials
and upon public records, and have further assumed and relied upon, without
independent investigation, the truth and accuracy of all factual representations
and warranties of all parties to the Loan Documents.

               We have assumed (i) all natural persons have legal capacity, (ii)
the genuineness of all signatures of all parties other than Borrower, (iii) the
conformity to authentic original documents of all documents submitted to us as
copies and the authenticity of all documents submitted to us as originals, (iv)
that each of the Guarantor Subsidiaries listed in Schedule 4.4 to the Loan
Agreement (the "Guarantor Subsidiaries") is duly organized, validly existing and
in good standing under the laws of its jurisdiction of incorporation or
organization and in each other jurisdiction where the conduct of its business or
the ownership of its Properties makes qualification or registration to transact
business necessary, (v) as to all parties other than the Borrower, the due
authorization, execution and delivery of the Loan Documents, (vi) the validity
and enforceability of the Loan Documents against all parties thereto other than
Borrower and the Guarantor Subsidiaries, (vii) that each of the Bank Parties has
the requisite power and authority, has obtained all necessary consents, licenses
and permits, has taken all necessary action and has complied with any and all
applicable laws with which such Bank Party is required to comply, in each case
relating to or affecting the matters and actions contemplated by the Loan
Documents, (viii) that each of the Bank Parties (other than the Arranger) is a
national bank, state bank or similar financial institution and is an exempt
lender under Article XV of the California Constitution or statutes enacted
pursuant thereto and (ix) that the Loan Documents have not been modified,
amended, terminated or revoked in any respect, and remain in full force and
effect as of the date hereof.

               On the basis of the foregoing, and relying thereon, and with the
qualifications herein set forth, we are of the opinion that:

               1. Borrower is a corporation duly incorporated, validly existing
and in good standing under the General Corporation Law of the State of Delaware,
and its certificate of incorporation does not limit the term of its existence.

               2. Borrower has all requisite corporate power and authority to
conduct its business, to own and lease its Properties and to execute, deliver
and perform all of its obligations under the Loan Documents to which it is a
party.
<PAGE>   103

Bank of America, N.A.
May 10, 2000
Page 3

               3. The execution, delivery, and performance by Borrower of the
Loan Documents to which it is a party have been duly authorized by all necessary
corporate action.

               4. The execution, delivery, and performance of the Loan Documents
by Borrower do not violate any provision of Borrower's certificate of
incorporation or bylaws, and the execution, delivery, and performance by
Borrower and each Guarantor Subsidiary of the Loan Documents to which it is a
party do not violate any Requirement of Law applicable to Borrower or such
Guarantor Subsidiary imposed by the laws of the United States of America or the
State of California that, in our experience, is normally applicable to general
business entities in relation to transactions of the type contemplated by the
Loan Documents.

               5. Except as have heretofore been obtained, no authorization,
consent, approval, order, license or permit from, or filing, registration, or
qualification with, or exemption from any of the foregoing from, any
Governmental Agency under any Requirement of Law imposed on Borrower or any
Guarantor Subsidiary by the laws of the United States of America or the State of
California, in each case as such Requirements of Law exist on the date hereof,
is or will be required to authorize or permit the execution, delivery and
performance by Borrower or any Guarantor Subsidiary of the Loan Documents to
which it is a party.

               6. Each of the Loan Documents to which Borrower or any Guarantor
Subsidiary is a party will, when executed and delivered by Borrower or such
Guarantor Subsidiary, as the case may be, constitute the legal, valid and
binding obligation of Borrower or such Guarantor Subsidiary, as the case may be,
enforceable against Borrower or such Guarantor Subsidiary, as the case may be,
in accordance with its terms.

               In addition to any assumptions, qualifications and other matters
set forth elsewhere herein, the opinions set forth above are subject to the
following:

               (a) Our opinion with respect to the legality, validity, binding
effect and enforceability of any Loan Document, agreement or provision is
subject to the effect of any applicable bankruptcy, insolvency, fraudulent
conveyance, fraudulent transfer and equitable subordination, reorganization,
moratorium or similar law affecting creditors' rights generally and to the
effect of general principles of equity, including (without limitation) concepts
of materiality, reasonableness, estoppel, good faith and fair dealing
(regardless of whether considered in a proceeding in equity or at law). We
express no opinion as to the availability of equitable remedies. In applying
such equitable principles, a court, among other things, might not allow a
creditor to accelerate the maturity of a debt or enforce a guaranty thereof upon
the occurrence of a default deemed immaterial or for non-credit reasons or might
decline to order a debtor to perform covenants. Such principles applied by a
court might also include a requirement that a creditor act with reasonableness
and in good faith.

               (b) Certain rights, remedies and waivers of the Loan Documents
may be unenforceable in whole or in part, but the inclusion of such provisions
does not affect the validity of the Loan Documents taken as a whole and, except
as set forth in subparagraph (a) above, the

<PAGE>   104

Bank of America, N.A.
May 10, 2000
Page 4

Loan Documents taken as a whole contain adequate provisions for enforcing
payment of the Obligations; however, the unenforceability of such provisions may
result in delays in or limitations on the enforcement of the parties' rights and
remedies under the Loan Documents (and we express no opinion as to the economic
consequences, if any, of such delays or limitations).

               (c) We call your attention to the following matters as to which
we express no opinion:

                      (i) the agreements in the Loan Documents to indemnify the
Bank Parties against costs or expenses or liability notwithstanding such
parties' acts of negligence or willful misconduct;

                      (ii) provisions in the Loan Documents for payment or
reimbursement of costs, fees and expenses or indemnification for claims, losses
or liabilities to the extent any such provision may be determined by a court or
other tribunal to be in an unreasonable amount, to constitute a penalty or to be
contrary to public policy;

                      (iii) the agreements in the Loan Documents to the
jurisdiction or venue of a particular court, to the waiver of the right to jury
trial or to be served with process by service upon a designated third party;

                      (iv) any of the waivers or remedies contained in the Loan
Documents, whether or not any Loan Document deems any such waiver or remedy
commercially reasonable, if such waivers or remedies are determined (1) not to
be commercially reasonable under applicable law, (2) to conflict with mandatory
provisions of applicable law, (3) to be taken in a manner determined to be
unreasonable or not performed in good faith or with fair dealing or with honesty
in fact or (4) to be broadly or vaguely stated or not to describe the right or
duty purportedly waived with reasonable specificity;

                      (v) provisions in the Loan Documents which may be
construed as imposing penalties or forfeitures, late payment charges or an
increase in interest rate, upon delinquency in payment or the occurrence of a
default;

                      (vi) any power of attorney granted under the Loan
Documents;

                      (vii) provisions in the Loan Documents to the effect that
rights or remedies are not exclusive, that every right or remedy is cumulative
and may be exercised in addition to any other right or remedy, that the election
of some particular remedy does not preclude recourse to one or more others or
that failure to exercise or delay in exercising rights or remedies will not
operate as a waiver of any such right or remedy;

                      (viii) provisions in the Loan Documents which expressly or
by implication waive or limit the benefits of statutory, regulatory or
constitutional rights, unless and

<PAGE>   105

Bank of America, N.A.
May 10, 2000
Page 5

to the extent the statute, regulation or constitution explicitly allow such
waiver or other limitation;

                      (ix) the effect of Section 1698 of the California Civil
Code which, among other matters, provides that a written contract may be
modified by an oral agreement to the extent such agreement is performed by the
parties;

                      (x) the effect of Section 1670.5 of the California Civil
Code which provides that a court may not enforce or may limit the application of
a contract or portions thereof which it finds as a matter of law to have been
unconscionable at the time the contract was made; and

                      (xi) the effect of (1) any modification or alteration of
the Loan Documents or other agreements with Borrower affecting the obligations
of Borrower, (2) an election of remedies by the Bank Parties, or (3) any other
action by the Bank Parties that materially prejudices any Guarantor Subsidiary
if such modification, election or action occurs without notice to the Guarantor
Subsidiaries and without giving the Guarantor Subsidiaries an opportunity to
cure any default by Borrower.

               Our opinions expressed herein are limited to the laws of the
State of California, the General Corporation Law of the State of Delaware and
the federal laws of the United States, and we do not express any opinion herein
concerning any other law, including, but not limited to, ordinances, regulations
or practices of any county, city or other government agency or body within the
State of California.
