           WHEREAS, the Company and River have entered into the Merger

           WHEREAS, the Company and GLGR Acquisition Corp., a Delaware

           NOW, THEREFORE, in consideration of the mutual agreements herein
 contained and intending to be legally bound hereby and other good and
 valuable consideration, the parties hereto agree as follows: 
  
           1.  Definitions.  Capitalized terms used herein and not otherwise
 defined herein shall have the meaning provided therefor in the Merger
 Agreement.
  
           2. GlobeGround Merger Agreement.  River agrees that
 notwithstanding any provisions to the contrary contained in the Merger
 Agreement, including without limitation the provisions of clauses (i) and
 (ii) of Section 8.01(f) of the Merger Agreement, River shall not exercise
 and hereby waives any and all rights it may have to terminate the Merger
 Agreement resulting from or arising out of any or all of the following: 
 (a) the execution by the Company of the GlobeGround Merger Agreement; (b)
 any recommendation made by the Company's Board of Directors (the "Board")
 or the Special Committee of the Board (the "Special Committee") to the
 Company's stockholders or otherwise in support or favor of the GlobeGround
 Merger Agreement or the transactions contemplated thereby; (c) any
 withdrawal, modification or change by the Board or the Special Committee of
 their recommendation so that the Board or the Special Committee is not in
 favor of the Merger Agreement or the transactions contemplated thereby in
 connection with the GlobeGround Merger Agreement; or (d) any other actions
 taken by the Board or the Special Committee in support or furtherance of
 the GlobeGround Merger Agreement or the transactions contemplated thereby. 
 In addition, River hereby agrees that no action or actions taken by the
 Company, the Board or the Special Committee in connection with or
 furtherance of the GlobeGround Merger Agreement or the transactions
 contemplated thereby shall operate as or constitute a breach of any of the
 terms, covenants, representations, warranties or conditions of the Merger
 Agreement.  The foregoing notwithstanding, effective March 17, 1999 all
 rights which River may have had to terminate the Merger Agreement and which
 were hereby waived, shall be reinstated and again shall be in full force
 and effect if, and only if, as of such date, the GlobeGround Merger
 Agreement has not been terminated, including, without limitation, the right
 to receive a payment from the Company to reimburse River for Expenses as
 provided in Section 8.05(b) of the Merger Agreement in connection with a
 termination of the Merger Agreement by River pursuant to clauses (i) or
 (ii) of Section 8.01(f) thereof.  Nothing contained herein shall in any way
 limit or restrict the Company's right or ability to at any time terminate
 the Merger Agreement in accordance with Section 8.01(g) thereof.  No waiver
 or amendment is being given by River with respect to any transactions other
 than transactions contemplated by the GlobeGround Merger Agreement, or with
 respect to any bidder other than GlobeGround or GLGR, and nothing contained
 herein shall in any way limit or restrict River's ability to terminate the
 Merger Agreement in accordance with its terms except as specifically
 provided herein with respect to the GlobeGround Merger Agreement or the
 transactions contemplated thereby.
  
           3.  Effectiveness.  This Waiver Agreement shall not be effective,
 and the provisions hereof  shall be of no force or effect, unless and until
 the Company enters into the GlobeGround Merger Agreement.
  
           4.  Counterparts.  This Waiver Agreement may be executed in any
 number of counterparts and by different parties hereto in separate
 counterparts, each of which when so executed shall be deemed to be an
 original but all of which taken together shall constitute one and the same
 agreement.
  
           5.  Governing Law.  This Waiver Agreement shall be governed by,
 and construed in accordance with, the laws of the State of Delaware without
 regard to the conflict of laws rules thereof.
  
           IN WITNESS WHEREOF, the Company and River have caused this Waiver
 Agreement to be executed by their respective officers thereunto duly
 authorized on this 15th day of February 1999.
