                  Re:      Option on Brennan Shares

Gentlemen:

                  NPD, Inc. ("NPD") has entered into a Stock Purchase  Agreement
dated  December 5, 1996, as amended (the "Purchase  Agreement"),  with Robert E.
Brennan  ("Seller")  pursuant to which the Purchaser has agreed to purchase from
the Seller  2,904,016  shares of the common stock, par value $2.00 per share, of
International   Thoroughbred  Breeders,  Inc.  ("ITB")  (the  "Shares")  for  an
aggregate purchase price of $11,616,064.

                  In consideration for AutoLend Group, Inc.  ("AutoLend") making
a loan to NPD in the amount of  $2,904,016,  NPD  granted to  AutoLend an option
(the  "Option")  to  purchase  the  Shares  under the terms and  subject  to the
conditions  set forth in the Option  Agreement  between NPD and  AutoLend  dated
December  5,  1996,  a copy  of  which  is  attached  hereto  as  Annex  "A" and
incorporated herein by reference )(the "Option Agreement").

                  On January 13, 1997,  the United States  Bankruptcy  Court for
the District of New Mexico,  before which  proceedings  are pending  relating to
AutoLend as debtor,  issued a Temporary Restraining Order the effect of which is
to prevent AutoLend from making the  aforementioned  loan to NPD.  Consequently,
due to the lack of consideration  for the Option,  NPD has terminated the Option
Agreement with AutoLend.

                  In  consideration  for  Casino-Co  Corporation   ("Casino-Co")
making a loan to NPD in the amount of $2,904,016.00,  pursuant to the terms of a
Loan Agreement dated of even date herewith  between NPD and Casino-Co (the "Loan
Agreement"),  NPD hereby grants to Casino-Co  the Option,  on the same terms and
subject  to the same  conditions  set forth in the  attached  Option  Agreement;
provided,  however, that the Option Agreement shall automatically  terminate and
be of no force and effect if AutoLend repays in full all

amounts due and owing  Casino-Co  from NPD under the Loan  Agreement and related
Secured  Promissory  Note  within  twenty (20) days from the date  hereof;  and,
provided,  further, however, that notwithstanding the foregoing or anything else
contained herein,  (i) the Option shall not become  exercisable unless and until
the parties and the grant of the Option to Casino-Co  have received all required
consents and approvals,  including,  without limitation, the approvals of Robert
E. Brennan  ("Brennan") and the United States  Bankruptcy Court for the District
of  New  Jersey,   before  which  certain  proceedings   involving  Brennan,  as
debtor-in-possession,  are pending,  and (ii) should such required  consents and
approvals  not be obtained,  then the grant of the Option to Casino-Co  shall be
rescinded  and shall be deemed to be void ab initio,  it being the  intention of
the  parties  that  neither the grant of the Option to  Casino-Co  nor any other
action  taken  pursuant  to or in  connection  with  the  Loan  Agreement  shall
constitute a breach or violation of Loan  Documents,  the Purchase  Agreement or
any order,  decree,  document or instrument  related thereto.  NPD and Casino-Co
agree to use their  best  efforts  to obtain  all such  necessary  consents  and
approvals.

                  If the foregoing collectively  represents the understanding of
Casino-Co with respect to the grant of the Option, kindly execute a copy of this
letter where  indicated  below and return the executed copy to the  undersigned,
whereupon this letter  agreement shall become a valid and binding  obligation of
the  parties and shall inure to the  benefit of the  respective  successors  and
assigns.

                                   Sincerely,

                                    NPD, Inc.
