                             AMENDMENT TO AGREEMENT

         This Amendment  ("Amendment")  to the Option  Agreement  dated June 13,
1996  (the  "Option")  is  made  this  8th day of  August  1997,  but  effective
retroactive  to the date of the Option,  by and between  Nona  Morelli's II Inc.
("Optionor") and Joseph Monterosso ("Optionee").

         WHEREAS,  pursuant to the Option, Optionee has the right to purchase up
to 250,000  shares of Series B  Preferred  Stock (the "B  Preferred  Shares") of
NuOasis Gaming Inc., now known as Group V Corporation ("Group V"), at a price of
$13.00 per share; and,

         WHEREAS, on June 4, 1997 (the "June 1997 Modification") Optionor agreed
with Optionee to accept certain securities, consisting of shares of common stock
of Network Long Distance Inc., a Delaware corporation (the "Network Shares"), in
lieu of the cash towards the purchase price on the unexercised  portion of the B
Preferred Shares; and,

         WHEREAS,  Optionee  has not yet been able to effect the transfer of the
Network Shares to Optionor and there is some  uncertainty  that such  securities
can be transferred prior to the expiration of the Option; and,

         WHEREAS,  Optionor is willing to extend the term of the Option pursuant
to the terms of this Amendment upon the terms and conditions hereof.

         NOW,  THEREFORE,  in consideration  for the covenants and promises made
herein,  and for other good and  valuable  consideration,  the  sufficiency  and
adequacy  of which is hereby  mutually  acknowledged  and agreed by the  parties
hereto, Optionee and Optionor hereby agree as follows:

1.       The  parties  mutually  agree and the  Option is hereby  extended:  the
         Option shall expire on August 15, 1997.

2.       The  parties  mutually  agree and the  Option is  hereby  amended:  the
         purchase price for each B Preferred  Share,  unexercised as of the date
         hereof, is approximately $72.20 per share.

3.       Optionor  agrees to accept  $1,585,467,  consisting of $121,959 in cash
         and  195,006  shares of the  Network  Shares,  valued at  approximately
         $1,463,508,  or $7.50  per  share on a  discounted  basis,  as the full
         purchase price on 21,959 shares of the remaining B Preferred Shares not
         previously purchased (the "Phase III Purchase").

4.       Optionee  and Optionor  mutually  agree that the Option as to 100,000 B
         Preferred Shares remaining unexercised,  giving effect to the Phase III
         purchase, shall hereby terminate.

Except as amended and modified by this  Amendment,  the terms and  conditions of
the Option shall otherwise remain in force and effect as stated therein.
