     (xiv) The Datapoint  Corporation  Supplemental  Executive  Retirement  Plan

     (xv) Asher B. Edelman,  in his capacity as Escrow Agent (in such  capacity,
the  "Escrow  Agent")  for the  Benefit  of the  Holders  of Record of  Dynacore
Holdings  Corporation  on February  24, 2003,  owned no shares of Common  Stock;
however,  each share of the  250,000  shares of Series A  Convertible  Preferred
Stock and share of the 1,127,000 shares of Series B Convertible  Preferred Stock
held in escrow (collectively,  the "Preferred Stock") is convertible at any time
into  7.25  shares  of Common  Stock  and is  entitled  to one vote per share of
Preferred Stock on any matter  presented to the holders of the Common Stock. The
Escrow  Agent does not have any  pecuniary  interest in the shares of  Preferred
Stock held in escrow  (the  "Escrowed  Stock")  and is not  authorized  to sell,
convert or otherwise  dispose of any shares of Escrowed Stock.  The Escrow Agent
does have the power to vote the Escrowed Shares.  Accordingly,  by reason of the

own 9,983,250 shares constituting 32% of the Common Stock outstanding.  However,
the Escrow Agent disclaims any beneficial  ownership in the Escrowed Shares. The
foregoing  determination  of the  percentage  of the  Common  Stock  outstanding
assumes that all of the shares of Escrowed Stock have been converted into shares
of  Common  Stock.  Such  assumption  is made  only for  purposes  of this  Item
5(a)(xv). For so long as the shares of Escrowed Stock are held in escrow and are
reported in this Item 5(a)(xv) by the Escrow Agent,  none of the other Reporting
Persons will separately report beneficial ownership of their respective portions
of the  Escrowed  Stock or the  shares  of  Common  Stock  into  which  they are
convertible .

     (xvi)  Certain  other  persons  who  are  related  to,  affiliated  with or
customers  of Mr.  Edelman own Common  Stock but are not members of the group of
reporting  persons due to the absence of voting or  dispositive  power over such
shares. Such persons include:  (A) Penelope Edelman,  Mr. Edelman's former wife,
who owned 411 shares of Common Stock constituting less than .1% shares of Common
Stock  outstanding;  and (B)  Three  Uniform  Gifts to Minors  Accounts  for the
benefit of  children  of Mr.  Edelman,  of which Mr.  Edelman's  former  wife is
custodian,  own 13,172 shares of Common Stock  constituting less than .1% of the
Common Stock outstanding;

     (xvii) To the best knowledge of the Reporting  Persons,  certain directors,
officers  and/or  general  partners of the  Reporting  Persons own the following
amounts of Common Stock (based upon information  reported by the Company or such
individuals in public filings):  (A) Gerald N. Agranoff,  a director of Canal, a
general  partner of Edelman Family  Partnership,  and a Trustee of the Datapoint
Plan, currently owns 6,618 shares of Common stock, constituting less than .1% of

general partner of Edelman Family  Partnership,  an executive officer of Edelman
Management  and a Trustee of the Datapoint  Plan  currently owns 1,481 shares of
