                        SHARE PURCHASE AND SALE AGREEMENT

         This Share Purchase and Sale Agreement  (the  "Agreement")  is executed
this 5th day of June, 2001, as agreed to by the parties on, and effective as of,
March 31,  2001,  by and between  Azul  Holdings  Inc.,  a Delaware  corporation
("Azul"),  and  Tudor  Trust,  a trust of which  Jeffrey  L.  Neuman is the sole

                                    RECITALS

         WHEREAS:

         1. Until the recent private placement by Xyvision Enterprise Solutions,
Inc.,  a  Delaware  corporation  ("XyEnterprise"),  of  shares  of its  Series A
preferred stock,  XyEnterprise was a majority owned subsidiary of Azul and after
giving effect to the XyEnterprise private placement Azul holds approximately 47%
of the outstanding shares of XyEnterprise capital stock.

         2. Tudor Trust holds  approximately  70% of the  outstanding  shares of
Azul capital stock and 19% of the  outstanding  shares of  XyEnterprise  capital
stock.

         3. Azul has  determined  that  holding a  majority  of the  outstanding
shares of XyEnterprise  capital stock is in Azul's best interests and desires to
purchase  additional shares of XyEnterprise  capital stock from Tudor Trust such
that XyEnterprise is again a majority owned subsidiary of Azul.

         4. Azul has  requested  that Tudor  Trust sell  shares of  XyEnterprise
capital  stock to Azul in  connection  with the  foregoing,  and Tudor  Trust is
willing to sell shares of  XyEnterprise  capital stock to Azul upon the terms of
this Agreement.

         NOW THEREFORE, in consideration of the representations, warranties and
agreements set forth herein, Azul and Tudor Trust agree as follows:

         Section 1.1 The Share  Purchase and Sale.  Subject to the terms hereof,
Azul hereby  purchases  from Tudor Trust and Tudor  Trust  hereby  sells to Azul
575,000 shares of XyEnterprise  Class A common stock,  $.001 par value per share
(the "Transferred  XyEnterprise  Shares"),  held by Tudor Trust, in exchange for
the  issuance by Azul to Tudor Trust of 1,092,500  shares of Azul common  stock,
$.03 par value per share (the  "Issued  Azul  Shares").  The  parties  agree and
acknowledge  that the  foregoing  exchange  ratio  reflects a  valuation  of the
Transferred  XyEnterprise  Shares based on recent  XyEnterprise  stock  issuance
transactions  and a valuation of the Issued Azul Shares based on the last quoted
price for Azul common stock on the OTC Bulletin Board on March 31, 2001.

         Section 1.2 Deliveries. Tudor Trust shall deliver to Azul duly endorsed
stock certificates representing the Transferred XyEnterprise Shares, appropriate
irrevocable  stock  powers,  and such other  instruments  as Azul may require to

Azul.  Azul shall in turn  deliver to Tudor  Trust a stock  certificate  for the
Issued Azul Shares,  which  certificate  shall bear a customary  securities  law
restrictive legend.
