       capacity as  Executive  Vice  President  of L-P,  and shall make  himself
       available,  as  reasonably  necessary,  in  person  and by  telephone  to
       cooperate  and provide  assistance  to L-P  regarding  pending and future
       government investigations,  pending and future administrative actions and
       pending  or  future   litigation,   for  which  he  has  or  enjoys  such

       has  questioned  Hanna  regarding  certain  activities  concerning  L-P'S
       acquisition  of  GreenStone  Industries,  Inc. L-P has advanced and shall
       continue to advance Hanna's reasonable counsel fees and expenses, if any,
       in this and any related matter. Both parties agree that Hanna's rights to
       such advanced funds shall be governed by the Delaware General Corporation
       Law and L-P's bylaws regarding  indemnification,  and Hanna undertakes to
       repay  to L-P the full  amount  of any  such  advanced  funds if it shall
       ultimately be determined that he is not entitled to indemnification  with
       respect to them.

10/29/988:06 AM                                                                2

       financial services  consistent with its current  practices,  through Ayco
       Company,  L.P.,  through December 31, 1998, and including  preparation of
       his 1998 income taxes.

6.     Hanna understands that he has, by this Agreement, been advised to consult
       with an attorney of his choice  before  signing.  Hanna also  understands
       that he has up to twenty-one  (21) full days to consider  whether to sign
       this  Agreement.  By signing on the date shown below,  Hanna  voluntarily
       elects to forego waiting 21 full days to sign the Agreement.

       calendar days following his execution of this agreement, Hanna may revoke
       this  Agreement  by  providing  L-P  with  written  notification  of such
       revocation  and  that  this  Agreement  shall  not  become  effective  or
       enforceable until such revocation period has lapsed.

       of his  employment he has had and will continue to have access to certain

       not at any time,  whether during or after his employment with L-P, use or
       disclose to any person for any purpose other than for the benefit of L-P,
       any  Confidential  Information,  or permit any person to use,  examine or
       make copies of any documents,  files, data or other  information  sources
       which  contain or are  derived  from  Confidential  Information,  whether

       and officers of L-P, or if

10/29/988:06 AM                                                                3
