Dear Mr. Antioco:


     Blockbuster Inc. ('Blockbuster'), having an address at 1201 Elm Street,
Dallas, Texas 75270, agrees to employ you and you agree to accept such
employment upon the following terms and conditions:

     l.   TERM. Your employment hereunder shall commence on July 15, 1999 and,
unless terminated by Blockbuster or you pursuant to paragraph 8 hereof, shall
continue through and until June 15, 2002. The period from July 15, 1999 through
June 15, 2002 shall hereinafter be referred to as the 'Employment Term'
notwithstanding any earlier termination of your employment pursuant to paragraph

     2.   DUTIES. During the Employment Term, you agree to devote your entire
business time, attention and energies to the business of Blockbuster. You will
be Chairman, Chief Executive Officer of Blockbuster and you agree to perform
such duties, and such other duties reasonable and consistent with such office as
may be assigned to you from time to time by the Chief Executive Officer (the
'CEO') of Viacom Inc. ('Viacom') or a Deputy Chairman of Viacom until
Blockbuster completes its initial public offering (the 'IPO') of its Class A
Common Stock (the 'Blockbuster A Stock') and thereafter as may be assigned from
time to time by the Blockbuster Board of Directors. However, nothing in this
Agreement shall preclude you from serving on the Boards of Directors of Main
Street & Main Inc. and any charitable, educational, religious, public interest
or public service organization, in each instance not inconsistent with
Blockbuster, or from devoting reasonable periods of time to the aforementioned
organizations, provided that such activities do not interfere with the
performance of your duties and responsibilities hereunder. You will have such
authority as is necessary for the performance of your duties as Chairman, Chief
Executive Officer of Blockbuster, within the authorization limits established by
the Viacom Board of Directors for management and consistent with on-going
policies developed by Viacom's senior management before the IPO and thereafter
within the authorization limits established by the Blockbuster Board of
Directors. Your principal place of business shall be at Blockbuster's
headquarters in the Dallas, Texas metropolitan area.

          (i)    Your Bonus for each calendar year during your employment with
                 Blockbuster under this Agreement will be determined in
                 accordance with Blockbuster's Senior Executive Short-Term
                 Incentive Plan (the 'Senior Executive STIP') or Viacom's
                 Short-Term Incentive Plan (the 'STIP'), as applicable, as the

          (ii)   Your Bonus for any full calendar year during the Employment
                 Term before the IPO occurs shall be determined in accordance
                 with the STIP. Your Bonus for the calendar year in which the
                 IPO occurs and for each subsequent calendar year or portion
                 thereof during the Employment Term shall be determined in
                 accordance with the Senior Executive STIP.

          (iii)  Your Target Bonus for each of the calendar years during the
                 Employment Term shall be 125% of Salary and the annual rate of
                 Deferred Compensation (as defined in paragraph 3(c)) for such
                 year. Your Bonus for calendar year 2002 may be pro-rated.

          (iv)   Your Bonus for each calendar year shall be payable by February
                 28 of the following year.

          (c) DEFERRED COMPENSATION: In addition to your Salary and Bonus, you
shall earn, in respect of each calendar year during the Employment Term,
commencing with the calendar year 2000, an additional amount ('Deferred
Compensation'), the payment of which (together with the return thereon as
provided in this paragraph 3(c)) shall be deferred until January of the first
calendar year in which you cease to be an executive officer of Blockbuster for

maintained by Blockbuster for your account, the balance of which account shall
periodically be credited (or debited) with the deemed positive (or negative)
return calculated in the same manner and at the same times, as the deemed return
on your account is determined under Blockbuster's Excess 401(k) Plan, as such
plan may be amended from time to time. Blockbuster's obligation to pay the
Deferred Compensation, including the return thereon provided for in this
paragraph 3(c)) shall be an unfunded obligation to be satisfied from the general
funds of Blockbuster.

          (d) BLOCKBUSTER STOCK OPTIONS:

          (i)    IPO COMPLETION GRANT AND INITIAL ANNUAL GRANT. Upon the
                 successful completion of the IPO, you shall receive stock
                 options to purchase one million (1,000,000) shares of the
                 Blockbuster A Stock (the 'IPO Grant') issued at fair market
                 value at the time of grant, vesting in five (5) equal equal
                 installments on the first, second, third, fourth and fifth
                 anniversaries of the date of grant. The IPO Grant represents
                 your IPO completion grant and your initial annual grant.

          (ii)   SUBSEQUENT ANNUAL GRANTS. In addition to the IPO Grant, you
                 shall receive, upon each of the first and second anniversaries
                 of the IPO, a grant of stock options with respect to the
                 Blockbuster A Stock (a 'Subsequent Annual Grant'), issued at
                 fair market value at the time of grant, with an aggregate
                 exercise price equal to Six Million Dollars ($6,000,000) for
                 each Subsequent Annual Grant. To illustrate, if the fair market
                 value of the Blockbuster A Stock was $30 per share on the date
                 of grant, you would receive a Subsequent Annual Grant of stock
                 options to purchase 200,000 shares of Blockbuster A Stock. The
                 Subsequent Annual Grants shall vest in four equal installments
                 on the first, second, third and fourth anniversaries of the
                 date of grant.

     4.   BENEFITS. You shall be entitled to participate in such medical, dental
and life insurance, 401(k), pension and other plans as Blockbuster may have or
establish from time to time and in which you would be entitled to participate
pursuant to the terms thereof. The foregoing, however, shall not be construed to
require Blockbuster to establish any such plans or to prevent the modification
or termination of such plans once established, and no such action or failure
thereof shall affect this Agreement. It is further understood and agreed that
all benefits you may be entitled to as an employee of Blockbuster shall be based
upon your Salary and Deferred Compensation, as set forth in paragraphs 3(a) and
(c) hereof, and not upon any bonus compensation due, payable or paid to you
hereunder, except where the benefit plan expressly provides otherwise. You shall
be entitled to four (4) weeks vacation.

not directly or indirectly engage in or participate as an officer, employee,
director, agent of or consultant for any business directly competitive with any
business that Viacom or Blockbuster is in or may enter into during the
Employment Term, nor shall you make any investments in any company or business

confidential information of Blockbuster, Viacom or any of Viacom's affiliates
(except as may be required by law or in the performance of your duties hereunder
consistent with Blockbuster's policies) and that you will comply with any
confidentiality obligations of Blockbuster or Viacom to a third party, whether
under agreement or otherwise. Notwithstanding the foregoing, confidential

or any other person who directly or indirectly receives such information from
you or at your direction or (ii) is or becomes available to you on a
non-confidential basis from a source which is entitled to disclose it to you.

          (c) NO EMPLOYEE SOLICITATION. You agree that, during the Employment

hereby irrevocably assign and agree to assign any and all of your right, title

results and proceeds of your services that cannot be assigned in the manner
described above, you unconditionally and irrevocably waive the enforcement of
such rights. This paragraph 6(d) is subject to, and shall not be deemed to
limit, restrict, or constitute any waiver by Blockbuster of any rights of
ownership to which Blockbuster may be entitled by operation of law by virtue of
Blockbuster or any of its affiliates being your employer.

          (e) LITIGATION. You agree that, during the Employment Term, for one
(1) year thereafter and, if longer, during the pendancy of any litigation or

performance of your duties hereunder) with respect to the facts or subject
matter of any pending or potential litigation, or regulatory or administrative
proceeding involving any of Blockbuster, Viacom or any of Viacom's affiliates,
other than any litigation or other proceeding in which you are a
party-in-opposition, without giving prior notice to Blockbuster or Blockbuster's

          (f) NO RIGHT TO GIVE INTERVIEWS OR WRITE BOOKS, ARTICLES, ETC. During
the Employment Term, except as authorized by Blockbuster or Viacom or in the

          (g) RETURN OF PROPERTY. All documents, data, recordings, or other
property, whether tangible or intangible, including all information stored in
electronic form, obtained or prepared by or for you and utilized by you in the
course of your employment with Blockbuster or any of its affiliates shall remain

employment for any reason, Blockbuster reserves the right, to the extent
permitted by law and in addition to any other remedy Blockbuster may have, to
deduct from any monies otherwise payable to you the following: (i) the full
amount of any debt you owe to Blockbuster, Viacom or any of Viacom's affiliates
at the time of or subsequent to the termination of your employment with
Blockbuster, and (ii) the value of the Blockbuster property which you retain in
your possession after the termination of your employment with Blockbuster. In
the event that the law of any state or other jurisdiction requires the consent
of an employee for such deductions, this Agreement shall serve as such consent.

          (h) NON-DISPARAGEMENT. You agree that you shall not, during the
Employment Term and for one (1) year thereafter, in any communications with any
customer or client of Blockbuster, Viacom or any of Viacom's affiliates,

Blockbuster, Viacom or any of Viacom's affiliates or any of their officers,
directors, agents or employees.

          (i) INJUNCTIVE RELIEF. Blockbuster has entered into this Agreement in
order to obtain the benefit of your unique skills, talent, and experience. You
acknowledge and agree that any violation of paragraphs 6(a) through (h) hereof
will result in irreparable damage to Blockbuster and Viacom, and, accordingly,
Blockbuster and Viacom may obtain injunctive and other equitable relief for any
breach or threatened breach of such paragraphs, in addition to any other
remedies available to Blockbuster and Viacom.

          (j) SURVIVAL; MODIFICATION OF TERMS. Your obligations under paragraphs

intention and the intention of Blockbuster that such restrictions and remedies
shall be

enforceable to the fullest extent permissible by law. If it shall be found by a
court of competent jurisdiction that any such restriction or remedy is
unenforceable but would be enforceable if some part thereof were deleted or the
period or area of application reduced, then such restriction or remedy shall
apply with such modification as shall be necessary to make it enforceable.

     7.   INCAPACITY. In the event you become totally medically disabled and
cannot substantially perform your duties at any time during the Employment Term,
the Blockbuster Board of Directors at any time after such disability has
continued for 60 consecutive days, may determine that Blockbuster requires that
such duties and responsibilities be performed by another executive. In the event
you become disabled, you will receive your Salary for the first 26 weeks of
consecutive absence. Thereafter, you will be eligible to receive benefits under
Blockbuster's Long-Term Disability ('LTD') program in accordance with its terms.
Upon receipt of benefits under the LTD program, you will also be entitled to

                 taxes, for the calendar year in which such benefits commence;

          (ii)   pro-rated Deferred Compensation for the calendar year in which
                 such benefits commence and Deferred Compensation attributable
                 to prior calendar years, payable, together with the return
                 thereon as provided in paragraph 3(c), prior to January 31 of

                 benefits commence; and

          (iii)  the vesting of all stock options granted to you with respect to
                 the Blockbuster A Stock which have not become exercisable on or
                 prior to the date on which benefits commence under the LTD
                 program will be accelerated and such stock options, together
                 with all stock options granted to you with respect to the
                 Blockbuster A Stock which are exercisable on or prior to the
                 date on which such benefits commence, will be exercisable until
                 one (1) year after the date on which such benefits commence,
                 or, if earlier, the expiration date of such stock options.

     8.   TERMINATION.

          (a) TERMINATION FOR CAUSE. Blockbuster may, at its option, terminate
this Agreement forthwith for 'cause', and Blockbuster shall thereafter have no
further obligations under this Agreement, including, without limitation, any
obligation to pay Salary, Deferred Compensation or Bonus or provide benefits
under this Agreement. For purposes of this Agreement, termination of this
Agreement for 'cause' shall mean termination for embezzlement, fraud or other
conduct which would constitute a felony, conviction of a felony, or willful
unauthorized disclosure of confidential information, or if you at any time
materially breach this Agreement (including, without limitation, your willful
failure, neglect of or intentional refusal to

later than ten (10) business days after the date it is given. Blockbuster shall
have ten (10) business days from the giving of such notice to cure the alleged

                        date of the termination of your employment under
                        paragraph 8(b) or 8(c) and such stock options will be
                        exercisable until six (6) months (or, if provided under
                        the terms of the plan governing such options, until one
                        (1) year) after the date of such termination;

PROVIDED, HOWEVER, you shall be required to mitigate the amount of any payment
provided for in (i), (ii), (iii) and (iv) of this paragraph 8(d) by seeking
other employment or otherwise (I.E., by self-employment), and the amount of any

for any other cash compensation shall be made, for eighteen (18) months after
the termination of your employment or for the period commencing with the
termination of your employment and ending on the last day of the Employment
Term, whichever is shorter. The payments provided for in (i) above are in lieu
of any severance or income continuation or protection under any Viacom or
Blockbuster plan that may now or hereafter exist. The payments and benefits to
be provided pursuant to this paragraph 8(d) shall constitute liquidated damages,
and shall be deemed to satisfy and be in full and final settlement of all
obligations of Blockbuster to you under this Agreement.

          (e) TERMINATION OF BENEFITS. Notwithstanding anything in this
Agreement to the contrary (except as otherwise provided in paragraph 8(d) with
respect to medical, dental and life insurance), coverage under all Blockbuster
benefit plans and programs (including, without limitation, vacation, 401(k),
excess 401(k), pension plan, excess pension plan, LTD, car insurance, accidental
death and dismemberment and business travel and accident insurance) will
terminate upon the termination of your employment except to the extent otherwise
expressly provided in such plans or programs.

          (f) NON-RENEWAL. In the event that Blockbuster does not extend or
renew this Agreement at the end of the Employment Term on no less favorable
terms, the vesting of all stock options granted to you with respect to the
Blockbuster A Stock that are not exercisable as of the end of the Employment
Term shall be accelerated and such stock options, together with all stock
options (if any) granted to you with respect to the Blockbuster A Stock which
are exercisable at the end of the Employment Term, will be exercisable until six
(6) months (or, if provided under the plan governing such stock options, until
one (1) year) after the end of the Employment Term.
