AGREEMENT


                   This is an agreement dated June 10, 1997 between Len-
         nar Corporation, a Delaware corporation ("Lennar"), Warburg,
         Pincus Investors, L.P., a Delaware limited partnership (the
         "Stockholder"), and Pacific Greystone Corporation, a Delaware
         corporation ("Greystone").

                   Whereas, Lennar and Greystone ("Greystone") propose
         to enter into a Plan and Agreement of Merger on the date of
         this Agreement (as it may be amended or supplemented, the
         "Merger Agreement") providing for the merger of Lennar into
         Greystone (the "Merger");

                   Whereas, the Stockholder owns in the aggregate
         8,411,854 shares of Common Stock, par value $0.01 per share, of
         Greystone (the "Greystone Common Stock"); those shares of
         Greystone Common Stock, as they may be adjusted by any stock
         dividend, stock split, recapitalization, combination or ex-
         change of shares, merger, consolidation, reorganization or
         other change or transaction of or by Greystone, are referred to
         in this Agreement as the "Warburg Shares";

                   Whereas, as a condition to its willingness to enter
         into the Merger Agreement, Lennar has requested that the Stock-
         holder enter into this Agreement;

                   Now, therefore, to induce Lennar to enter into, and
         in consideration of its entering into, the Merger Agreement,
         and in consideration of the mutual covenants and agreements set
         forth in this Agreement, and for other good and valuable con-
         sideration, the receipt and sufficiency of which are hereby
         acknowledged, the parties to this Agreement agree as follows:


                                    ARTICLE I

                          REPRESENTATIONS AND WARRANTIES

                   The Stockholder represents and warrants to Lennar as
         follows:

                   1.1  Authority.  The Stockholder is a limited part-
         nership duly organized, validly existing and in good standing
         under the laws of the State of Delaware.  The Stockholder has
         all power and authority necessary to enable it to enter into
         this Agreement and to carry out the transactions contemplated
         by this Agreement.  This Agreement has been duly and validly
         authorized, executed and delivered by the Stockholder and con-
         stitutes a legal, valid and binding obligation of the Stock-
         holder enforceable against the Stockholder in accordance with
         its terms.

                   1.2  Non-Contravention.  Neither the execution and
         delivery of this Agreement by the Stockholder nor the consumma-
         tion of the transactions contemplated by this Agreement or by
         any document to be delivered in accordance with this Agreement
         will violate, result in a breach of, or constitute a default
         (or an event which, with notice or lapse of time or both would
         constitute a default) under, the limited partnership agreement
         of the Stockholder, any agreement or instrument to which the
         Stockholder is a party or by which it 
         
         
         
                                   






         is bound, any law, or any order, rule or regulation of any court 
         or governmental agency or other regulatory organization having 
         jurisdiction over the Stockholder.

                   1.3  Approvals and Consents.  No governmental fil-
         ings, authorizations, approvals or consents, or other govern-
         mental action is required for the execution and delivery of
         this Agreement by the Stockholder, the performance by the
         Stockholder of its obligations under this Agreement or the con-
         summation by the Stockholder of the transactions contemplated
         by this Agreement.

         the Agreement dated as of June 26, 1996 by and between Grey-
         stone and the Stockholder (the "Prior Voting Agreement"), (a)
         the Warburg Shares constitute more than 50% of the outstanding
         shares of Greystone Common Stock and have more than 50% of the
         voting power of all the outstanding stock of Greystone of all
         classes, (b) the Stockholder owns the Warburg Shares, free and
         clear of any liens, claims, security interests, proxies, voting
         trusts or agreements, understandings or arrangements which
         would in any way restrict or impair the Stockholder's right to
         vote the Warburg Shares in the Stockholder's sole discretion or
         could require the Stockholder to sell or transfer any of the
         Warburg Shares (whether upon default on a loan or otherwise)
         before December 31, 1997, and (c) the Stockholder has the sole
         voting power and sole power to issue instructions with respect
         to the Warburg Shares.

                   Each of Lennar and Greystone hereby represents and
         warrants to the Stockholder as follows:

                   1.5  Authority.  Such party is a corporation duly
         organized, validly existing and in good standing under the laws
         of the State of Delaware.  Such party has all power and author-
         ity necessary to enable it to enter into this Agreement and to
         carry out the transactions contemplated by this Agreement.
         This Agreement has been duly and validly authorized, executed
         and delivered by such party and constitutes a legal, valid and
         binding obligation of such party enforceable against such party
         in accordance with its terms.

                   1.6  Non-Contravention.  Neither the execution and
         delivery of this Agreement by such party nor the consummation
         of the transactions contemplated by this Agreement or by any
         document to be delivered in accordance with this Agreement will
         violate, result in a breach of, or constitute a default (or an
         event which, with notice or lapse of time or both would consti-
         tute a default) under, the certificate of incorporation or by-
         laws of such party, any agreement or instrument to which such
         party is a party or by which it is bound, any law, or any or-
         der, rule or regulation of any court or governmental agency or
         other regulatory organization having jurisdiction over such
         party.

                   1.7  Approvals and Consents.  No governmental fil-
         ings, authorizations, approvals or consents, or other govern-
         mental action is required for the execution and delivery of

                           COVENANTS OF THE STOCKHOLDER
                   
                   The Stockholder hereby covenants and agrees with Len-
         nar as follows:

                   2.1  Vote for Merger.  Except as provided in Para-
         graph 2.5 or Article V, at any meeting of stockholders of
         Greystone called to vote upon the Merger and the Merger Agree-
         ment or at any adjournment or postponement thereof or in any
         other circumstances upon which a vote, consent or other ap-
         proval with respect to the Merger and the Merger Agreement is
         sought, the Stockholder shall vote (or cause to be voted) at
         least 50% of the outstanding shares of Greystone Common Stock
         in favor of the Merger, the adoption by Greystone of the Merger
         Agreement, other matters relating to the approval of the terms
         of the Merger Agreement and each of the other transactions con-
         templated by the Merger Agreement.

                   2.2  Vote Against Alternative Proposals.  Except as
         provided in Paragraph 2.5 or Article V, at any meeting of
         stockholders of Greystone or at any adjournment or postponement
         thereof or in any other circumstances upon which the Stock-
         holder's vote, consent or other approval is sought, the Stock-
         holder shall vote (or cause to be voted) at least 50% of the
         outstanding shares of Greystone Common Stock against (i) any
         proposal or offer with respect to any direct or indirect (A)
         acquisition or purchase of what would be 15% or more of the
         outstanding Greystone Common Stock, (B) acquisition or purchase
         of any equity securities of any significant subsidiary of
         Greystone (as the term "significant subsidiary" is defined in
         Securities and Exchange Commission Regulation S-X), (C) acqui-
         sition or purchase of all or any significant portion of the
         assets of Greystone or any subsidiary of Greystone, or (D) any
         merger, consolidation, business combination, recapitalization,
         liquidation, dissolution or similar transaction involving
         Greystone or any of its subsidiaries, (ii) any change in the
         persons who constitute the Board of Directors of Greystone or
         (iii) any change in the present capitalization of Greystone or
         any amendment of Greystone's certificate of incorporation or
         by-laws or other proposal or transaction involving Greystone or
         any of its subsidiaries, if in the case of clause (i), (ii) or
         (iii) such transaction, change, amendment or other proposal or
         transaction would in any manner impede, frustrate, prevent or
         nullify the Merger, the Merger Agreement or any of the other
         transactions contemplated by the Merger Agreement or would
         reasonably be likely to result in any of the conditions to
         Greystone's obligations under the Merger Agreement not being
         fulfilled.

                   2.3  Transfers.  Except as provided in Paragraph 2.5

         transfer, pledge, assignment or other disposition of, any
         Warburg Shares to any person other than pursuant to the Merger
         and the Merger Agreement, unless such transferee agrees in
         writing to be bound by the terms of this Agreement with respect
         to the Warburg Shares transferred to it or (ii) enter into any
         voting arrangement, whether by proxy, voting arrangement, vot-
         ing agreement or otherwise, other than for the purpose of vot-
         ing the Warburg Shares as required by this Agreement.

                   2.4  No Solicitations.  Except as provided in Para-
         graph 2.5 or Article V, prior to the Effective Time, neither
         the Stockholder nor any of its affiliates nor any of their
         respective officers or directors shall, and the Stockholder
         will direct, and use its best efforts to cause, its employees,
         agents and representatives (including any investment banker,
         attorney or accountant retained by it or any of its affiliates)
         not to, directly or indirectly, initiate, solicit, encourage or
         otherwise facilitate any inquiries or the making of any pro-
         posal or offer with respect to a merger, reorganization, share
         exchange, consolidation or similar transaction involving
         Greystone, or any purchase of, or tender offer for, all or any
         significant portion of any equity securities of Greystone or of
         all or any significant portion of the assets of Greystone on a
         consolidated basis (any such proposal or offer being herein-
         after referred to as an "Acquisition Proposal"); provided
         however that nothing in this Agreement shall prevent any person
         from taking any action permitted or required pursuant to the
         Merger Agreement to be taken by such person in his capacity as
         a director of Greystone and all such actions taken by any per-
         son who is a director of Greystone shall be deemed to be taken
         by such person in his capacity as a director.  The Stockholder
         agrees that it will promptly advise Lennar of the receipt of
         any Acquisition Proposal.

                   2.5  Payment as a Result of Termination of Merger
         Agreement.  If Greystone terminates the Merger Agreement pursu-
         ant to Paragraph 7.1(d) or (e) of the Merger Agreement as a
         result of a Superior Proposal (as defined in the Merger Agree-
         ment) (having complied with all the prerequisites to the termi-
         nation of the Merger Agreement under the applicable one of
         those Paragraphs),

                   (a)  If, when the Merger Agreement is terminated pur-
              suant to Paragraph 7.1(d) or (e) of the Merger Agreement,
              the Stockholder confirms in writing to Lennar that it is
              bound by the provisions of this Paragraph 2.5 as a result
              of the termination of the Merger Agreement, Warburg will
              be released from its obligations under this Article II.

                   (b)  In the event that such Superior Proposal or any
              other Superior Proposal shall be consummated on or prior
              to the one year anniversary of the termination of the
              Merger Agreement pursuant to Paragraph 7.1(d) or (e)
              thereof (the "Final Date"), the Stockholder shall pay to
              Lennar (the "Warburg Payment") an amount, net of any taxes
              payable notwithstanding the provisions of this Agreement,
              equal to (x) the product of (A) the excess, if any, of the
              Superior Price (as defined below) over $17.50 and (B) the
              number of shares of Greystone Common Stock owned by the
              Stockholder as of the date of consummation of the Superior
              Proposal, less (y) any payments made under Section 16(b)
              of the Exchange Act as a result of the consummation of the
              Superior Proposal or the satisfaction of its obligations
              hereunder.
         
                   (c)  The Warburg Payment shall be made within 10 days
              following the consummation of the Superior Proposal.  In
              the event any portion of the consideration received by the
              Stockholder in the Superior Proposal consists of securi-
              ties or other property other than cash (the "Non-Cash Con-
              sideration"), the Warburg Payment may consist in whole or
              in part of the Non-Cash Consideration.  To the extent that
              the Warburg Payment consists of any Non-Cash Consider-
              ation, for purposes of determining whether the Stockholder
              has made the Warburg Payment, such Non-Cash Consideration
              shall be valued in accordance with clause 
              
              
                                       
                                       -4-
             





              (e) hereof as of the date of the consummation of the Superior 
              Proposal and not as of the date of delivery of the Warburg 
              Payment.  

                   (d)  For purposes hereof, the term "Superior Price"
              shall mean the value (determined in accordance with clause
              (e) hereof) as of the date of consummation of the Superior
              Proposal of the consideration actually received per share
              of Greystone Common Stock by the Stockholder in the Supe-
              rior Proposal (valued as described below).

                   (e)  For purposes of this Section 2.5, the value of
              any consideration as of any date shall be (i) to the ex-
              tent consisting of cash, the amount thereof, (ii) to the
              extent consisting of securities listed on a national secu-
              rities exchange or on the over-the-counter market, as re-
              ported by the National Association of Securities Dealers,
              Inc. Automated Quotations System, the average daily clos-
              ing price thereof on such exchange or market on the five
              trading days prior to the date of determination, (iii) to
              the extent consisting of other securities, the fair value
              thereof as of such date as determined in good faith by the
              parties hereto.  


                                   ARTICLE III

                               RESTRICTION ON SALE
                   3.1  Restriction on Sale.  If the Merger shall occur,
         the Stockholder shall not sell or otherwise dispose of any
         shares of stock of the corporation which survives the Merger
         (the "Company Stock") which the Stockholder receives as a
         result of the Merger with regard to Warburg Shares ("Warburg
         Company Stock") on or prior to the date which is six months
         after the Effective Time of the Merger (as defined in the
         Merger Agreement).
                             
                                    ARTICLE IV

                              ADDITIONAL AGREEMENTS

                   4.1  Designation of Directors; Number.  For as long
         as the Stockholder and its affiliates shall in the aggregate
         beneficially own a number of shares of Company Stock of the
         surviving corporation of the Merger (the "Company") equal to 5%
         or more of the Adjusted Outstanding Company Stock (as defined
         below), the Company's Board of Directors shall consist of no
         more than nine members, at least five of whom shall not be
         officers or employees of the Company or any of its subsidiar-
         ies, or officers, employees of directors of LPC, Inc. or any of
         its subsidiaries.  For as long as the Stockholder and its af-
         filiates shall in the aggregate beneficially own a number of
         shares of Company Stock equal to (i) 5% or more of the Adjusted
         Outstanding Company Stock, but less than 10% of the Adjusted
         Outstanding Company Stock, the Stockholder shall have the right
         to nominate, and the Company will make its best efforts to
         cause to be elected or appointed, one individual to serve as a
         director on the Company's Board of Directors (a "Warburg Nomi-
         nee") and (ii) 10% or more of the Adjusted Outstanding Company
         Stock, the Stockholder shall have the right to nominate and the
         Company will make its best efforts to cause to be elected or
         appointed to serve as director on the Company's Board of Direc-
         tors, two Warburg Nominees.  Without limiting the foregoing,
         the Company agrees that upon 
         
         
         
                                   -5-
        






         receipt from the Stockholder of the name(s) of the Warburg 
         Nominee(s) the Company shall nominate such nominee(s) for election 
         to the Company's Board of Directors and recommend to the Company's 
         stockholders that they vote for such Warburg Nominee(s).  As long 
         as the Stockholder shall beneficially own a number of shares of 
         Company Stock equal to 5% or more of the Adjusted Outstanding 
         Company Stock, upon request of the Stockholder, one such nominee 
         shall be entitled to be a member of the Independent Directors 
         Committee established pursuant to the Company's by-laws and of each 
         other committee of the Board of Directors (other than the Executive
         Committee) so requested by the Stockholder.  In the case of
         death, resignation or removal of any Warburg Nominee, the Com-
         pany will use its best efforts to cause another Warburg Nominee
         to replace the former Warburg Nominee as a Director as promptly
         as practicable and to appoint a Warburg Nominee to replace the
         former Warburg Nominee on the committees on which the former
         Warburg Nominee has served.  For purposes of this Agreement,
         the term "Adjusted Outstanding Company Stock" shall mean the
         number of shares of Common Stock and Class B Common Stock of
         the Company outstanding immediately following the Merger, equi-
         tably adjusted for any stock splits, reverse stock splits,
         stock dividends or similar recapitalization transactions (but
         excluding shares of Common Stock or Class B Common Stock other-
         wise issued after the Merger).

                   The Company shall take or cause to be taken all ac-
         tion within its respective power and authority as may be re-
         quired to effect the foregoing.  

                   4.2  Consent Required for Certain Actions.  For as
         long as the Stockholder and its affiliates shall in the aggre-
         gate beneficially own a number of shares of Company Stock equal
         to 5% or more of the Adjusted Outstanding Company Stock, with-
         out the prior written consent of the Stockholder, the Company
         shall not, and shall not permit any of its subsidiaries to,
         directly or indirectly, (a) issue shares of Company Stock (or

         ment is held to be illegal, invalid or unenforceable under any
         present or future law, and if the rights or obligations of any
         party hereto under this Agreement will not be materially and
         adversely affected thereby, (i) such provision will be fully
         severable, (ii) this Agreement will be construed and enforced
         as if such illegal, invalid or unenforceable provision had
         never comprised a part hereof, (iii) the remaining provisions
         of this Agreement will remain in full force and effect and will
         not be affected by the illegal, invalid or unenforceable provi-
         sion or by its severance herefrom and (iv) in lieu of such il-
         legal, invalid or unenforceable provision, there will be added
         automatically as a part of this Agreement a legal, valid and
         enforceable provision as similar in terms to such illegal, in-
         valid or unenforceable provision as may be possible.

                   6.10  Enforcement.  The parties agree that irrepar-
         able damage would occur in the event that any of the provisions
         of this Agreement were not performed in accordance with their
         specific terms or were otherwise breached.  It is accordingly
         agreed that the parties shall be entitled to an injunction or
         injunctions to prevent breaches of this Agreement and to en-
         force specifically the terms and provisions of this Agreement
         in any Federal court located in the State of Delaware or in a
         Delaware state court, this being in addition to any other rem-
         edy to which they are entitled at law or in equity.  In addi-
         tion, each of the parties hereto (i) consents to the personal
         jurisdiction of any Federal court located in the State of Dela-
         ware or any Delaware state court in any action or proceeding
         relating to or arising out of this Agreement or any of the
         transactions contemplated hereby, (ii) agrees that such party
         will not attempt to deny or defeat such personal jurisdiction
         by motion or other request for leave from any such court, (iii)
         agrees that such parties will not seek to change the venue of
         any such action or proceeding or otherwise to move any such
         action or proceeding to another court, whether because of
         inconvenience of the forum or otherwise (provided that nothing
         in this Section will prevent a party from removing an action or
         proceeding from a Delaware state court to a Federal Court lo-
         cated in the State of Delaware), (iv) agrees that such party
         will not bring any action relating to this Agreement or any of
         the transactions contemplated hereby in any court other than a
         Federal court sitting in the State of Delaware or a Delaware
         state court and (v) waives any right to trial by jury with re-
         spect to any claim or proceeding related to or arising out of
         this Agreement or any of the transactions contemplated hereby.
         
                   IN WITNESS WHEREOF, each party hereto has caused this
         Agreement to be signed by its officer thereunto duly authorized
         as of the date in the first paragraph of this Agreement.
