     Re:  Playboy TV Latin America/Iberia Expansion
          -----------------------------------------

Dear Tony:

     I am writing to confirm the terms and conditions on which Playboy TV-Latin 
America, LLC (the "Venture") will expand its operations into Spain and Portugal
("Iberia").

     1.  Expansion of Territory. The Venture's Operating Agreement shall be 
         ----------------------
amended to provide that the Venture is authorized to operate the Playboy TV 
("PTV") and AdulTVision ("ATV") television services in Iberia. The parties will
mutually approve a Budget and Business Plan for the operations in Iberia, and 
the existing Budget and Business Plan (which are exhibits to the Operating
Agreement) will be amended to reflect the joint operations in Latin America and
Iberia.

         The Operating Agreement shall be amended to provide that for the 
purposes of triggering either party's right to terminate the Venture early for 
failure to meet projections, the measure of "net revenue per household" shall be
determined separately for Latin America and Iberia. Therefore, a failure in one 
territory will only trigger the right to terminate operations in that territory,
and the Venture will continue to operate in the other territory.

     2.  Media/Windows. All Playboy-branded programming will be available to the
         -------------
Venture after April 31, 1997. The unbranded series "Woman" (consisting of 26 
half-hour episodes) is the only Playboy Entertainment Group, Inc. ("PEG") 
program licensed in Spain, and that license expires in 2002.

              Each PTV and ATV program will be licensed to the Venture for the 
same term, and with the same windows, as in Latin America. As in the existing
deal, upon the reversion of rights in PTV programs, PEG may not sell those 
programs on a block or branded basis.

              The Venture will have a license to exploit the PTV and ATV 
programs in the same media as in Latin America, with the Venture to also have
the rights for "expanded basic" or "basic" cable if PTV is to be offered to 
consumers in that manner.


         3.  Program Costs.
             -------------
 
             3.1  PTV

             3.2  ATV. $*** per movie, increasing by ***% per year for the 
                  ---
first *** years, and *** thereafter.


         4.  Royalty. Playboy Enterprises Inc. will grant the Venture a license
             -------
to use the Playboy trademarks, service marks and trade name in Iberia in 
exchange for a royalty payment equal to a percentage of the adjusted gross 
revenue (as defined in the Operating Agreement) of the Iberian operations. ***

         5.  Ownership. The basic structure remains unchanged: 81% Cisneros/19%
             ---------
PEG, with PEG to have an option to increase to 49.9% at founder's price until 
the sooner of cash breakeven (for the aggregate operations of the Venture in 
both Latin America and Iberia) or the end of the fifth fiscal year.

             The Operating Agreement and the Program License Agreement (for PTV
programs) between the Venture and PEG provide

for the deferral of a portion of the program license fees owed by the Venture 
for Latin America (the "Deferred Fees"). With respect to such Deferred Fees:

        a. If PEG does not exercise its option to acquire additional percentage 
interests in the Venture prior to the date that the Deferred Fees become 
payable, PEG will forgive, $*** of Deferred Fees.

        b. If PEG exercises its option to acquire additional percentage 
interests in the Venture prior to the date that the Deferred Fees become 
payable, PEG will forgive an amount of the Deferred Fees equal to: *** 

     6. Launch Date. The Venture shall launch both the PTV and ATV services in 
        -----------
Iberia prior to June 30, 1997, subject to the Venture having entered into an 
agreement for carriage of the services on a digital platform which permits such 
launch to occur by the date.

     7. Distribution. The Venture itself will distribute PTV and ATV in Iberia. 
        ------------
If the Venture determines that it would be beneficial for distribution or other 
reasons to associate with one or more local parties in Iberia, the Venture may 
grant distribution rights to such party(ies). The parties acknowledge that the 
Portuguese subsidiary of Grupo Abril would be a desirable equity participant 
and/or distributor of the services in Portugal.

     8. First Negotiation/Matching Right. In the event PEG (or any of its 
        --------------------------------
affiliates) decides to operate PTV, ATV or similar services in all or any 
territory of Sweden, Finland, Denmark, Norway, Germany, Australia, or 
Switzerland via a venture with a non-Playboy entity, Bloomfield Mercantile Inc. 
("Bloomfield") shall have a right of first negotiation to participate in such 
new venture and a matching right with respect to the terms offered by any third 
party. To the extent any third party proposal includes carriage of the services,
Bloomfield would not be required to match that element of the proposal. To the 
extent that the entity whose offer Bloomfield has matched is an operator

of a digital platform or a dominant distributor of networks to cable in the 
subject territory, Bloomfield will not unreasonably prevent such venture from 
offering such distributor or operator an equity participation in the venture.

     9.  Documentation. Following execution of this letter, the parties agree to
         -------------
move expeditiously to amend the Operating Agreement and to execute a trademark 
license agreement and program license agreements for Iberia (with the 
boilerplate terms and conditions to be identical to those contained in the 
corresponding agreements for Latin America.)

    11.  Announcement. The parties intend to announce this agreement on 
         ------------
January 14, 1997 at the NATPE convention.

                                            Very truly yours,
