                  "5.1  Management.

                           5.1.1.   Board of Managers. Subject to the Act or
                  this Agreement, the powers of the Company shall be exercised
                  by or under the authority of, and the business and affairs of
                  the Company shall be managed by, the Board of Managers who
                  shall be responsible for the management and operations of the
                  Company and shall have all powers necessary to manage and
                  control the Company, to conduct its business, and to implement
                  any decision of the Members adopted pursuant to this
                  Agreement. The initial Board of Managers shall consist of four
                  (4) Representatives, two (2) of whom shall be appointed by the
                  Huttner Members (the "Initial Huttner Designees") and two (2)
                  of whom shall be appointed by Calton, Inc. (the "Initial
                  Calton Designees"). In the event of a Deadlock, Calton, Inc.
                  shall be entitled to appoint one (1) additional Representative
                  (the "Second Calton, Inc. Designee") who shall not be (i) an
                  officer, employee or director of Calton, Inc., (ii) any
                  individual that has a material relationship with Calton, Inc.
                  or (iii) an individual that is related by blood or marriage to
                  any officer, employee or director of Calton, Inc.; provided,
                  however, that the Second Calton Inc. Designee shall not become
                  a Representative unless the choice of the Designee is approved
                  by one (1) of the Initial Huttner Representatives (which
                  approval shall not be unreasonably withheld). If Calton, Inc.
                  and the Initial Huttner Representatives are not able to agree
                  upon the Second Calton, Inc. Designee within thirty days of
                  notice by Calton, Inc. to the Initial Huttner Members of the
                  proposed Second Calton, Inc. Designee, then either Calton,
                  Inc. or the Initial Huttner Designees may submit the matter
                  which is the subject of a Deadlock to the American Arbitration
                  Association for arbitration under the commercial arbitration
                  rules of that institution. The arbitration will be conducted
                  in Houston, Texas and the finding of the arbitrators will be
                  binding on all parties for all purposes. Each party will bear
                  its own


                                       8


                  expenses of any such arbitration; provided, however, that at
                  any time following the issuance of the final arbitration
                  ruling, the party prevailing in said proceeding may, at its
                  election and at the expense of the non-prevailing provide for
                  the entry of the award for enforcement purposes in any court
                  of competent jurisdiction. The number of Representatives
                  constituting the Board of Managers may be increased or
                  decreased from time to time by unanimous approval of the
                  Members. Representatives shall be elected by the Members as
                  provided in this Section 5.1.1 and Section 5.2.1, and each
                  Representative so elected shall hold office until his
                  successor is duly elected and qualified or until his or her
                  earlier death resignation, or removal. Any Representative may
                  resign at any time upon notice to the Company or may be
                  removed with or without cause, by the Member(s) having
                  appointed such Representative in accordance with this Section
                  V. A Representative need not be an employee of a Member or a
                  resident of the State of Delaware. Subject to the powers of
                  removal and replacement set forth above in this Section 5.1,
                  the Huttner Members hereby appoint Richard Dole and Frederick
                  A. Huttner as their initial Representatives and Calton Inc.
                  hereby appoints Anthony J. Calderone and Robert E. Naughton as
                  its initial Representatives."

                  thereof to any voting rights."

13.      Major Decisions. The following Section 5.2.7 is hereby added to the

         voted against such matter. Contemporaneous with the execution of this
         Amendment No. 1 to Operating Agreement, WHTP, West, Huttner, Dole and
