                   Whereas, Lennar Corporation ("Lennar") and 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 Miller Entities collectively own in the
         aggregate 9,944,130 shares of Class B Common Stock, par value
         $0.10 per share, of Lennar (the "Lennar Class B Stock"); those
         shares of Lennar Class B Stock, as they may be adjusted by any

         other change or transaction of or by Lennar, are referred to in
         this Agreement as the "Miller Shares"; 

                   Whereas, as a condition to its willingness to enter
         into the Merger Agreement, Greystone has requested that the
         Miller Entities 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:

         each Miller Entity shall vote (or cause to be voted) all of the

         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 (including the Spin Off)
         or would reasonably be likely to result in any of the condi-

         disposition of, any Miller Shares to any person other than pur-
         suant to the Merger and the Merger Agreement, unless such

         ment.

                   2.4  No Solicitations.  Prior to the Effective Time
         (as defined in the Merger Agreement), no Miller Entity nor any
         of its affiliates nor any of their respective officers, part-
         ners or directors shall, and each Miller Entity 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 other-
         wise facilitate any inquiries or the making of any proposal or
         offer with respect to a merger, reorganization, share exchange,
         consolidation or similar transaction involving Lennar, or any
         purchase of, or tender offer for, all or any significant por-
         tion of any equity securities of Lennar or of all or any sig-
         nificant portion of the assets of Lennar on a consolidated
         basis (any such proposal or offer being hereinafter 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 Lennar
         and all such actions taken by any person who is a director of
         Lennar shall be deemed to be taken by such person in his capac-
         ity as a director.  Each Miller Entity agrees that it will

         called to vote upon the election of a Warburg Nominee to the
         Company's Board of Directors or a Warburg Nominee's removal
         therefrom, or at any adjournment or postponement thereof or in
         any other circumstances upon which such a vote, consent or
         other approval is sought, each Miller Entity shall vote (or
         cause to be voted) all of the equity securities of the Company
         owned by it in favor of the election of the Warburg nominees
         and against their removal from the Board of Directors of the
         Company.  Each Miller Entity shall also vote (or cause to be
         voted) all of the equity securities of the Company owned by it
         in favor of, consent to, and take any and all other actions
         reasonably necessary to effect, the changes to the structure of
         the Company's Board of Directors set forth in Paragraph 4.1 of

                   2.6  Vote on Amendment.  (a)  Prior to the first to
         occur of the second anniversary of the Merger or the effective-
         ness of the Amendment (as such term is defined below), none of
         the Miller Entities will vote any equity securities of the Com-
         pany owned by them in favor of any merger, consolidation or
         other business combination that, if the Amendment were effec-
         tive, would require the Minority Vote (as defined below).

                        (b)  Each Miller Entity will vote all of its
         shares of common stock or Class B Common Stock of the Company
         in favor of the Amendment.

                   For purposes of this Agreement, "Amendment" means an
         amendment to the Company's Certificate of Incorporation to pro-
         vide that, in addition to any other vote required by the cer-
         tificate of incorporation, by law, by any rule of any securi-
         ties exchange or otherwise, any merger, 
         
         
                                      4
         






         consolidation or other business combination involving the Company 
         shall require the affirmative vote of the holders of at least a 
         majority of the issued and outstanding shares of common stock 
         (other than the Class B Common Stock of the Company) of the Company 
         (the"Common Stock"), voting as a single class (the "Minority
         Vote"), unless the type and amount of the consideration re-
         ceived by the holder of a share of Common Stock of the Company
         in such transaction is the same as that received by a holder
         of, a share of Class B Common Stock of the Company; provided,
         however that if shareholders are given the right to elect among
         differing kinds of consideration in such business combination,
         the foregoing requirement will be deemed satisfied if the
         holders of shares of Common Stock are given the same rights of
         election (including without limitation proration rights) as the
         holders of shares of Class B Common Stock of the Company.

                   2.7  Restriction on Sale.  Each Miller Entity agrees
         that until November 30, 1999, it shall not sell or otherwise
         dispose of any shares of stock of the Company which the Miller
         Entity receives as a result of the Merger with regard to Miller
         Shares unless (i) the transferee agrees to be bound by the pro-
         visions of this Agreement or (ii) after the sale, the Miller
         Entities hold in aggregate shares entitled to more than 50% of
         the votes in an election of directors of the Company.  Any sale
         or other disposition in violation of the terms hereof shall be
         null and void.

         tions within its respective power and authority to cause the
         Amendment to be approved by its shareholders.

         covenants and agreements contained in this Agreement shall sur-

                   5.7  Amendments.  This Agreement may be amended only
         by a document in writing signed by Lennar, Warburg, Greystone
         and each Miller Entity, and no amendment to Paragraph 2.6 or
         3.1 shall be effective unless it has been approved by both (i)
         the unanimous vote of the members of the Company's Board who
         are not Miller Entities, relatives of any Miller Entity or
         affiliates of the Miller Entities and (ii) the affirmative vote

         terparts will be deemed an original, but all of them together
         will constitute one and the same agreement.

                   5.9  Severability.  If any provision of this Agree-
         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 pro-
         vision or by its severance herefrom and (iv) in lieu of such
         illegal, 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,
         invalid or unenforceable provision as may be possible.

                   5.10  Enforcement.  The parties agree that irrepa-
         rable damage would occur in the event that any of the provi-
         sions of this Agreement were not performed in accordance with
         their specific terms or were otherwise breached.  It is accord-
         ingly agreed that the parties shall be entitled to an injunc-
         tion or injunctions to prevent breaches of this Agreement and
         to enforce specifically the terms and provisions of this Agree-
         ment in any Federal court located in the State of Delaware or
         in a Delaware state court, this being in addition to any other
         remedy to which they are entitled at law or in equity.  In
         addition, each of the parties hereto (i) consents to the per-
         sonal jurisdiction of any Federal court located in the State of
         Delaware or any Delaware state court in any action or proceed-
         ing 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 in-
         convenience 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
         located 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.
