         NOW, THEREFORE,  in consideration of the above premises,  the covenants
and agreements set forth herein, and other good and valuable consideration,  the
receipt and  sufficiency  of which are hereby  acknowledged,  the parties hereby
agree as follows:

          2.   129 hereby acknowledges and affirms its liability to Treasury for

               U.S. per day (the  "Obligation")  until paid.  129 hereby further
               acknowledges  and agrees  that it has no  defense,  counterclaim,
               right of offset, cross-complaint,  claim or demand of any kind or
               nature whatsoever that can be asserted to reduce or eliminate all
               or any part of its liability to Treasury for the Obligation,  nor
               any right to seek  affirmative  relief or  damages of any kind or
               nature  from   Treasury   arising  out  of  or  relating  to  the
               Obligation.  Notwithstanding the foregoing, Treasury acknowledges
               and confirms that, in regard to the Transaction, it has no claim,
               whether  known or unknown,  against  129's  officers,  directors,
               stockholders, agents or representatives at this time.

          3.   Treasury  hereby  agrees  to  extend  the  payment  date  of  the
               Obligation to on or before 5:00 p.m. Eastern Time, on January 31,
               2000.  Treasury  also  agrees  to  release  all  parties  hereto,
               including  their  officers  directors,  stockholders,  agents and
               representatives,  except  129,  from  any  liability  to pay  the
               Obligation.  Treasury specifically gives up its right to call the
               Mega stock or in any way  attempt to  reclaim or  repurchase  the
               Mega stock for  non-payment  of the  Obligation.  In that regard,
               Treasury  and  Whitehall  Enterprises,  Inc.  shall  execute  the
               Acknowledgement  and  Confirmation in the form attached hereto as
               Exhibit A.

          4.   Within  thirty (30) days from the date of this  Addendum,  Global
               shall  have  issued by the Royal  Bank of Canada  ("Bank") a full
               release for any and all liabilities Treasury may have to the Bank
               as a third  party  guarantor  regarding  Mega.  Global  agrees to
               secure this  release by paying off the term loans owed by Mega to
               the Bank, and guaranteed by Treasury.  Global agrees to execute a
               Guarantee and Indemnity  Agreement (the  "Guarantee") in favor of
               Treasury  in the amount  guaranteed  by  Treasury  to the Bank as
               security for Global's agreement to effect a release of Treasury's
               obligation  to the Bank.  The  Guarantee  will be cancelled  upon
               receipt by Treasury of the release from the Bank.

          5.   Upon the execution of this  Addendum,  Global shall purchase from
               Treasury  for  $100,000  U.S.  an  8%  Subordinated   Convertible
               Debenture  (the   "Debenture")  due  January  31,  2001.  If  the
               Obligation  is not  paid  on or  before  January  31,  2000,  the
               Debenture  shall be  cancelled  and the  $100,000  U.S.  shall be
               applied against the  Obligation.  If the Obligation is paid on or
               before  January 31, 2000,  Global shall have the right,  prior to
               the  Debenture's  due  date  or  redemption  date,  whichever  is
               earlier,  to  convert  the  Debenture  into  1,000,000  shares of
               Treasury common stock.

          6.   As collateral  security for 129's prompt and faithful payment and
               performance   of  the   Obligation,   and  any  and  all   future
               indebtedness   and  obligations  of  129  to  Treasury,   whether
               evidenced  or arising out of this  Addendum  or any other  future
               oral or written  agreement  between 129 and Treasury,  129 hereby
               grants and assigns to Treasury a  continuing  and  first-priority
               security  interest in and lien on all of 129's present and future
               assets,  including  accounts,   equipment,   inventory,   general
               intangibles,  chattel paper, deposit accounts,  goods,  documents
               and in any  and  all  other  personal  property  of 129  and  the
               proceeds (including, without limitation,  insurance proceeds) and
               products  of any  and  all of the  foregoing  (collectively,  the
               "Collateral").

          7.   The  Obligation and any and all accrued per diem thereon or other
               amounts  payable in connection  therewith shall mature and be due
               and payable in full on January 31, 2000 (the "Maturity Date").
