      6.  Amendment of Specific Provisions of Operating Agreement.  The
Operating Agreement is amended as follows:

     (a) Section 3.2.6 of the Operating Agreement is amended to read as follows:

      "3.2.6   If a Member shall cease to be  controlled  directly or indirectly
               by the  same  Persons  who  control  it as of the  date  of  that
               Member's  admission  to the  Company,  the Member  shall  provide
               written  notice  thereof to the other  Members.  On or before the
               expiration  of 30 days after such notice is received by the other
               Members,  such  other  Members  shall have the option to buy that
               Member's  Membership  Interest  at a purchase  price equal to the
               balance in that Member's  Capital  Account on the date the option
               is exercised.  If more than one of such other  Members  wishes to
               exercise such option, they shall exercise such option on the same
               date and  share in such  purchase  on a pro rata  basis  based on
               their respective  Sharing Ratios.  This paragraph shall not apply
               to  a  change  in  control   that  results  from  the  merger  or
               consolidation  of the  corporation  which  directly or indirectly
               controls a Member ("Parent Corporation") with another corporation
               or the  sale  of  all or  substantially  all of the  assets  of a
               Member's Parent Corporation if, in each such case, (a) the Parent
               Corporation  shall not have been formed for the principal purpose
               of directly or indirectly  controlling the Member, and (b) either
               (i) such Parent  Corporation shall be the continuing  corporation
               and shall continue to directly or indirectly  control the Member,
               or (ii) the  successor  corporation  (if  other  than the  Parent
               Corporation  of the Member) shall be a corporation  organized and
               existing  under the laws of the  United  States of  America  or a
               state  thereof or the  District  of Columbia  and such  successor
               corporation  shall  continue  to be  in  substantially  the  same
               business  as  the  Parent  Corporation.  This  Section  3.2.6  is
               intended to prohibit any kind of financing or corporate structure
               techniques  designed  to avoid  the  reach of the  right of first
               refusal provisions of Section 3.2 of this Agreement."

      (b) Section  3.2.7 of the  Operating  Agreement  is amended to replace the
phrase "Except as provided in Section 3.2.2, any" in the fifth line thereof with
the word "Any".


                                                       - 4 -





      (c)  Section  5.2.1 of the  Operating  Agreement  is amended to change the

5.4" .

      (d)  Section  5.2.2 (b) of the  Operating  Agreement  is amended to change
"Section 5.1 or 5.4" in the third line thereof to "Section 5.1, 5.2.3 or 5.4" .

      (e)  Section 5.2.3 is amended to read as follows:

      "5.2.3        Each  Member  agrees  that it  shall  make  payments  of its
                    respective Capital Contributions in accordance with requests
                    issued   pursuant  to  Section  5.2.1  and  Section   5.2.2;
                    provided,  however,  that a  Member  may  elect  not to make
                    Capital  Contributions  or  Loans  under  Section  5.3  with
                    respect to a change in the size,  design or  location of the
                    Facilities  if  such  change  would  increase  the  Member's
                    Commitment  as set forth in Paragraph 2 of the  Amendment to
                    Operating  Agreement  effective October 1, 1995 by more than
                    25% (a "Material  Change") or with respect to a Modification
                    if  it  (i)  does  not  vote  for  the  Material  Change  or
                    Modification,  as the case may be, and (ii) provides written
                    notice to all other  Members  within ten (10) days of a vote
                    for a  Material  Change  or a vote  under  Section  4.2.2 to
                    proceed  with a  Modification,  as the case may be,  that it
                    does not wish to make  Capital  Contributions  or Loans with
                    respect  to such  Material  Change or  Modification.  In the
                    event  the  Company  proceeds  with  a  Material  Change  or
                    Modification  after  one or more  Members  elect not to make
                    Capital  Contributions  or Loans with respect  thereto,  the
                    Sharing Ratios and Capital  Accounts of all Members shall be
                    adjusted to reflect the respective Capital  Contributions or
                    Loans of all Members."

      (f) Section  7.1.4(a) of the Operating  Agreement is amended to change the
