     (v)  A.B. Edelman Limited Partnership owned no shares of Common Stock.

     (vi) The  Uniform  Gifts to Minors  accounts  for Mr.  Edelman's  three (3)
          daughters for which he is custodian own no shares of Common Stock.

     (vii)Edelman Family  Partnership,  L.P. owned 37,500 shares of Common Stock
          constituting approximately .2% of the Common Stock outstanding.

     (ix) Michelle  Vrebalovich,  Mr. Edelman's spouse,  owned 198,649 shares of

          Stock constituting less than .1% of the Common Stock outstanding.

     (xi) Asher B. Edelman  owned 1,125 shares of Common Stock in a Keough plan.
          By reason of the  provisions of Rule 13d-3,  Mr. Edelman may be deemed
          to own  beneficially  the 400,307 shares of Common Stock  beneficially
          owned by the foregoing persons and himself, constituting approximately
          1.9% of the Common Stock outstanding.

     (xii)The  Canal  Corporation  Retirement  Plan  owned no  shares  of Common
          Stock.

     (xiii) The Datapoint  Corporation  Supplemental  Executive  Retirement Plan
          ("Datapoint  Plan") owned 71,253  shares of Common Stock  constituting
          .3% of the Common Stock outstanding.

     (xiv)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  provisions  of  Section  13(d)-3,  the

          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 .

     (xv) 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 no shares of Common Stock;  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 no
          shares of Common Stock.

     (xvi)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 the outstanding
          shares;  and (B) Irving  Garfinkel,  a Trustee of the  Datapoint  Plan
          currently  owns 1,481 shares of Common Stock,  constituting  less than
          .1%  of  the  outstanding  shares.  Mr.  Edelman  expressly  disclaims
          ownership of the foregoing shares.
