     (1)  For a period of ten (10) years from the date hereon (the "Period");

          (a)  Executive will not, directly or indirectly, engage or invest 
in, own, manage, operate, finance, control, or participate in the ownership, 
management, operation, financing, or control of, be employed by, associated 
with, or in any manner connected with, lend Executives' name or any similar 
name to, or render services or advice to, any business whose products or 
activities compete in whole or in part with the products or activities of the 
Company, which business is the manufacture and sale of building envelope 
systems and related products, modified bitumen (roofing and building 
materials and compounds), industrial emulsions, roof and driveway coatings 
and cement, and paving sealers, provided, however, that Executive may 
purchase or otherwise acquire up to (but not more than) five percent (5%) of 
any class of securities of any enterprise (but without otherwise 
participating in the activities of such enterprise) if such securities are 
listed on any national or regional securities exchange or have been 
registered under Section 12(g) of the Securities Exchange Act of 1934. 
Executive agrees that this covenant is reasonable with respect to its 
duration, geographical area, and scope.

or any other Person, (A) induce or attempt to induce any employee of the 
Company or the Company's parent entity to leave the employ of such company,

Company's parent entity, (C) employ, or otherwise engage as an employee, 
independent contractor, or otherwise, any employee of the Company or the 
Company's parent entity, or (D) induce or attempt to induce any customer, 
supplier, licensee, or business relation of the Company or the Company's 
parent entity to cease doing business with such company, or in any way 
interfere with the relationship between any customer, supplier, licensee, or 
business relation of any such company.

          (c)  Executive will not, directly or indirectly, either for himself 
or any other Person, solicit the business of any Person known to Executive to 
be a customer of the Company or the Company's parent entity, whether or not 
Executive had personal contact with such Person;

     (2)  If Executive breaches any covenant set forth in Subsection 3(1) of 
this Agreement, the term of such covenant will be extended by the period of 
the duration of such breach;

     (3)  Executive will not, at any time during or after the Period, 
disparage Henry, the Company or the Company's parent entity, or any of their 
shareholders, directors, officers, employees, or agents; and

                                      ARTICLE 4.

                                     COMPENSATION

Agreement, Henry and the Company will be entitled to the following remedies:

     (1)  Damages from Executive;

     (2)  In addition to its right to damages and any other rights it may 
have, to obtain injunctive or other equitable relief to restrain any breach 
or threatened breach or otherwise to specifically enforce the provisions of 
Sections 2 and 3 of this Agreement, it being agreed that money damages alone 
would be inadequate to compensate Henry or the Company and would be an 
inadequate remedy for such breach.

     (3)  The rights and remedies of the parties to this Agreement are

                                        WAIVER

     The rights and remedies of the parties to this Agreement are cumulative 
and not alternative. Neither the failure nor any delay by any party in 
exercising any right, power, or privilege under this Agreement will operate 
as a waiver of such right, power, or privilege, and no single or partial 
exercise of any such right, power, or privilege will preclude any other or 
further exercise of such right, power, or privilege or the exercise of any 
other right, power, or privilege. To the maximum extent permitted by 
applicable law, (a) no claim or right arising out of this Agreement can be 
discharged by one party, in whole or in part, by a waiver or renunciation of 
the claim or right unless in writing signed by the other party; (b) no waiver 
that may be given by a party will be applicable except in the specific 
instance for which it is given; and (c) no notice to or demand on one party 
will be deemed to be a waiver of any obligation of such party or of the right 
of the party giving such notice or demand to take further action without 
notice or demand as provided in this Agreement.

                                      ARTICLE 8.

                                    GOVERNING LAW

     This Agreement will be governed by the laws of the State of Delaware

                                        -4-



     Any action or proceeding seeking to enforce any provision of, or based 
on any right arising out of, this Agreement shall be brought against any of 
the parties in the federal and state courts of the State of Delaware, each of 
the parties consents to the jurisdiction of such courts (and of the 
appropriate appellate courts) in any such action or proceeding and waives any 
objection to venue laid therein. Process in any action or proceeding referred 
to in the preceding sentence may be served on any party anywhere in the world.

                                     ARTICLE 10.

                                    SEVERABILITY

     Whenever possible each provision and term of this Agreement will be 
interpreted in a manner to be effective and valid but if any provision or 
term of this Agreement is held to be prohibited by or invalid, then such 
provision or term will be ineffective only to the extent of such prohibition 
or invalidity, without invalidating or affecting in any manner whatsoever the 
remainder of such provision or term or the remaining provisions or terms of 
this Agreement. If any of the covenants set forth in Section 3 of this 
Agreement are held to be unreasonable, arbitrary, or against public policy, 
such covenants will be considered divisible with respect to scope, time, and 
geographic area, and in such lesser scope, time and geographic area, will be 
effective, binding and enforceable against Executive.

                                    ARTICLE 11.

                                   COUNTERPARTS

     This Agreement may be executed in one or more counterparts, each of 
which will be deemed to be an original copy of this Agreement and all of 
which, when taken together, will be deemed to constitute one and the same 
agreement.

                                    ARTICLE 12.
