          This Amendment No. 6 amends the Statement on Schedule 13D filed with
the Securities and Exchange Commission on June 3, 1993, as amended (the
"Statement") by Sumner M. Redstone and Viacom Inc. ("Viacom"). This Amendment
No. 6 is filed with respect to the shares of common stock, par value $.01 per
share (the "Common Stock"), of Discovery Zone, Inc., a Delaware corporation
(the "Issuer"), with its principal offices located at 205 North Michigan
Avenue, Chicago, Illinois  60601.  Capitalized terms used but not defined
herein have the meanings assigned to such terms in the Statement.

Item 2.   Identity and Background.
          -----------------------

          Item 2 is hereby amended and supplemented to reflect changes in the
directors and executive officers of Viacom as set forth on Schedule I attached
hereto.  Schedule I sets forth the following information with respect to each
such person:

          (i)       name;

          (ii)      business address (or residence where indicated); and

          (iii)     present principal occupation or employment and the name,
principal business and address of any corporation or other organization in which
such employment is conducted.

          All of the directors and executive officers of Viacom are citizens of
the United States.

          During the last five years, neither Viacom nor any person named in
Schedule I attached hereto (including Sumner M. Redstone) has been convicted in
a criminal proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.

Item 4.   Purpose of Transaction.
          ----------------------

          Item 4 of the Statement is hereby amended and supplemented as follows:

          Viacom and Blockbuster Entertainment Group, a division of
Viacom ("Blockbuster"), have entered into a five-year Management Services
Agreement dated April 17, 1995 (the "Management Services Agreement") with
the Issuer. Blockbuster has agreed to assume the management of the operational
and administrative functions of the Issuer, subject to certain closing
conditions. Blockbuster will be reimbursed for the costs and expenses incurred
in the provision of management services to the Issuer, and the Issuer will
issue to Viacom, on the effective date of the Management Services Agreement,
warrants (the "Warrants") to purchase an aggregate of 473,463 shares of a
new class of noncumulative convertible voting participating preferred stock
(the "Preferred Stock") of the Issuer.





                                  Page 4







          The Warrants will be divided into three classes, Series A Warrants,
Series B Warrants and Series C Warrants, which will be exerciseable for an equal
number of shares of Preferred Stock, will vest on the first, second and third
anniversaries of the effective date of the Management Services Agreement and,
except under certain circumstances, will not be exercisable until December 16,
1998.  Each share of Preferred Stock issuable upon exercise of the Warrants
will have a liquidation preference of $.10 per share, will be entitled to
noncumulative dividends in an amount equal to the greater of (x) 5% of the
liquidation preference per share, when, as and if declared by the board of
directors of the Issuer and (y) a pro rata share of the dividends paid with
respect to the Common Stock (based on the number of shares of Common Stock the
Preferred Stock is convertible into), will vote with the Common Stock as one
class on all matters submitted to the stockholders of the Issuer (based on the
number of shares of Common Stock the Preferred Stock is convertible into) and
will automatically convert into 24 shares of Common Stock, subject to
adjustment, immediately but only following a sale of the Preferred Stock to a
person unaffiliated with Viacom.  The exercise prices for the Series A Warrants,
Series B Warrants and Series C Warrants per share of the Common Stock into which
the Preferred Stock is convertible are $10.375, $11.931 and $14.317,
respectively.

          In addition, the non-Viacom directors of the Issuer other than Donald
F. Flynn have agreed to resign on the effective date of the Management Services
Agreement and the Issuer's current directors have agreed to cause nominees
designated by Viacom to be appointed to Issuer's board of directors.  Donald
F. Flynn has resigned as Chief Executive Officer of the Issuer and Steven R.
Berrard, the Chief Executive Officer of Blockbuster, has been appointed
interim Chief Executive Officer of the Issuer.

          Pursuant to a Stock Purchase Agreement dated as of April 17, 1995 (the
"Stock Purchase Agreement") among DKB, Inc., Kevin F. Flynn June, 1992 Non-
Exempt Trust and Brian J. Flynn June, 1992 Non-Exempt Trust, as sellers (the
"Sellers"), Donald F. Flynn, Kevin F. Flynn and Brian J. Flynn, as guarantors,
and Viacom and its indirect wholly owned subsidiary Blockbuster Discovery
Investment, Inc. ("BDI"), as purchasers (the "Purchasers"), subject to
regulatory and other closing conditions, (i) Viacom, through BDI, has agreed
to purchase 3,818,649 shares of Common Stock at a price of $6.50 per share
from the Sellers, following the exercise by the Sellers of warrants to acquire
shares of Common Stock, (ii) in order to allow the Purchasers to maintain their
ownership percentage of Common Stock at 49.99%, the Sellers have agreed to
grant to the Purchasers a two-year option to acquire up to 2,210,695 shares of
Common Stock at a price equal to 75% of their market price; provided, however,
                                                            --------  -------
that such price shall never be less than $6.50 or more than $12.50 per share,
and (iii) the Sellers have agreed to grant to the Purchasers a two-year right
of first offer covering an additional 1,205,156 shares of Common Stock.
Following the acquisition of the shares of Common Stock by the Sellers, upon
exercise of their warrants, and the purchase of the 3,818,649 shares of Common
Stock pursuant to the Stock Purchase Agreement, Viacom will own approximately
49% of the outstanding Common Stock, based upon the number of shares of Common
Stock outstanding as of April 17, 1995.

          Pursuant to a letter agreement dated April 17, 1995 (the "Letter
Agreement") among the Issuer, Blockbuster Family Fun, Inc. and Family
Entertainment Centers, Inc., the Issuer has agreed to acquire, subject to
regulatory and other conditions, the assets of two entertainment centers
currently operated under the "Block Party" name and mark from subsidiaries of
Viacom for the lesser of the cost of the entertainment centers and $15,000,000,
payable in ten year subordinated notes of the Issuer.

                    (g)   Limitation on Rights; Notification.
                          ----------------------------------
               Blockbuster's rights under this Agreement do not include the
               right to exercise any of the rights of the Company set forth
               in this Agreement, which shall remain with a special
               committee of the Board of Directors of the Company (the
               "Special Committee"), comprised of independent directors as
               such term is defined in the Schedule D to the By-Laws of
               National Association of Securities Dealers, Inc.
               ("Independent Directors"), or any agent appointed by such
               committee.  Blockbuster agrees to promptly notify the Board

               which Blockbuster becomes aware in the performance of its
               duties hereunder which could reasonably be expected to have
               a material effect on the assets, business, financial
               condition or operations of the Company; provided that a
               failure to so notify the Board of Directors shall not result
               in liability to Blockbuster except to the extent the Company
               is materially prejudiced thereby.

               SECTION 2.     Compensation for Services.
                              -------------------------

                    (a)   Quarterly Fee.  The Company will pay to
                          -------------
               Blockbuster or any agent designated by Blockbuster a
               quarterly fee equal to the actual costs, fees, expenses and
               reimbursements of the services provided, and a fair and
               reasonable allocation of overhead, during the preceding
               calendar quarter.  In the case of overhead, such cost shall
               be determined by allocating an appropriate percentage of
               Blockbuster's and Blockbuster Entities' overhead to the
               Company.  Without limiting the generality of the foregoing,
               such costs shall include, without limitation:

                          (i) Salaries of any of the Company's officers who
                    are officers or employees of Blockbuster or any
                    Blockbuster Entity and other employees of Blockbuster
                    or Blockbuster Entities who provide services to the
                    Company (collectively, "Blockbuster Employees"), and
                    the cost of employee benefit and bonus programs and
                    other employee costs for the Blockbuster Employees.
                    With respect to any Blockbuster Employee who does not
                    provide full-time services to the Company, the costs of
                    such salary, employee benefits and bonus programs, and
                    other employee costs, will be pro rated according to a
                    reasonable estimate of the amount of time such
                    Blockbuster Employee spends on the Company's business
                    in relation to the amount of time such person spends on
                    all matters for Blockbuster or a Blockbuster Entity and
                    its affiliates, including the Company;

                          (ii)     Travel and entertainment expenses of
                    Blockbuster Employees, which are incurred in the course
                    of providing services to the Company under this
                    Agreement;

                          (iii)    The actual cost of any third party
                    services, such as law firms, engineering firms, public
                    relations firms, consultants and accountants, as well
                    as other fees, charges, taxes (excluding any taxes on
                    Blockbuster's compensation under this Agreement) and
                    dues paid for by Blockbuster or any Blockbuster Entity
                    in the performance of this Agreement; and

                          (iv)     Miscellaneous fees and expenses,
                    including a fair and reasonable allocation of overhead,
                    incurred by Blockbuster and any Blockbuster Entity and
                    any agents thereof in providing services to the Company
                    under this Agreement.  Overhead, includes, but is not
                    limited to, the cost of office space, furniture,
                    computer systems, software and equipment, supplies,
                    postage, utilities, telephone, other equipment, freight
                    and handling, maintenance and taxes.

                    (b)   Payment of Quarterly Fee.  Blockbuster will
                          ------------------------
               submit to the Company a quarterly statement of the fee due
               hereunder.  The statement shall include the method of
               calculation of the fee in reasonable detail and shall be
               supported, if applicable, by vouchers and such other
               information as may be reasonably requested by the Company.
               Within 10 days of Blockbuster's delivery of the statement,
               the Company shall pay Blockbuster the amount of the fee due;
               provided, however, that if the Company reasonably objects to
               --------  -------
               any fee or portion thereof, the Company may withhold the
               amount disputed, provided that the Company furnishes to
               Blockbuster a detailed written statement of the Company's
               objection (a "Dispute Notice").  If the Company withholds
               all or any portion of any fees and delivers a Dispute Notice
               in accordance with the preceding sentence, the parties shall
               endeavor in good faith to resolve such dispute.  If such
               dispute is not resolved by the parties within 30 days after
               delivery of a Dispute Notice, the dispute shall be submitted
               to a firm of independent certified public accountants
               appointed by the parties.  The decision of such accountants
               shall be determined within 30 days after such appointment
               and shall be final and binding upon the parties.  Promptly,
               but in no event later than two business days following the
               resolution of any such dispute, the Company shall pay
               Blockbuster the amount of the fee due, if any (as determined
               by the parties hereto or by the independent certified public
               accountants), together with interest thereon at LIBOR  plus
               .75% per annum or the maximum permitted by law, whichever is
               lower, accruing from tenth day following the Company's
               receipt of the applicable fee statement.  "LIBOR" means the
               rate per annum (rounded upwards, if necessary to the next
               higher one hundred-thousandth of a percentage point) for
               deposits in United States dollars for a one-month period,
               which appears on the display designated as Page 3750 on the
               Telerate Service (or such other page as may replace Page
               3750 on that service or such other service as may be
               nominated by the British Bankers' Association as the
               information vendor for the purposes of displaying British
               Bankers' Association Interest Settlement Rates for United
               States dollar deposits) on the tenth day following the
               Company's receipt of the applicable fee statement (or if
               such day is not a day on which such rate is quoted, the next
               succeeding day on which such rate is quoted) and as adjusted
               on each one month anniversary of such date (or if such day
               is not a day on which such rate is quoted, the next
               succeeding day on which such rate is quoted) until the fee
               determined to be due is paid by the Company.  Blockbuster
               shall bear the expenses of such accounting firm if the
               amount of the fee due as determined by such accounting firm
               is less than 90% of the amount disputed (95% if the amount
               disputed is an annual fee); otherwise, the Company shall
               bear the expenses of such accounting firm.
          .
                    (c)   Company's Right to Inspect.  At the request of
                          --------------------------
               the Special Committee made not more frequently than once in
               any calendar year (regardless of whether any Dispute Notice
               has been presented by the Company) and at any time on and
               after the presentation of a Dispute Notice (and for so long
               as such dispute remains unresolved),



                                          7

               the Company shall have the right during normal business
               hours, and with reasonable notice to Blockbuster, to
               inspect, or cause to be inspected, the business, bookkeeping
               and accounting records of Blockbuster relating to its
               services under this Agreement.  The Special Committee may,
               at the Company's cost, engage independent certified public
               accountants or other representatives to assist it in the
               examination of such records and Blockbuster shall cooperate
               with such accountants or other representatives in any such
               inspection.

                    (d)   Issuance of the Warrants to Viacom.  In addition
                          ----------------------------------
               to the quarterly fee, in consideration of the services
               provided by Blockbuster, the Company will issue the Warrants
               to Viacom on or prior to the Effective Date.

               SECTION 3.     Limitation of Liability; Indemnification.
                              ----------------------------------------

                    (a)   Limitation of Liability.  Subject to Section 3(e)
                          -----------------------
               hereof, neither Blockbuster nor any Blockbuster Entity nor
               any of their officers, directors, employees, consultants or
               agents shall be liable to the Company or any Company Entity,
               or to any officer, director, employee, consultant or agent
               of the Company or any Company Entity, for any cost, damage,
               expense or loss, including, without limitation, any special,
               indirect, consequential or punitive damages of the Company
               or any Company Entity, or any such officer, director,
               employee, consultant or agent, arising as a result of or in
               connection with any service, advice or data Blockbuster or
               any Blockbuster Entity may provide or fail to provide to the
               Company or any Company Entity pursuant to this Agreement.

                    (b)   Indemnification of Blockbuster.  Subject to
                          ------------------------------
               Section 3(e) hereof, the Company shall indemnify Blockbuster
               and each Blockbuster Entity, and each of their officers,
               directors, employees, consultants and agents, and shall hold
               Blockbuster and each Blockbuster Entity and each such
               officer, director, employee, consultant and agent harmless
               against any damage, loss, cost or expense (including court
               costs and reasonable attorneys' fees as they are incurred)
               which Blockbuster and any Blockbuster Entity, or any such
               officer, director, employee, consultant or agent may sustain
               or incur by reason of any claim, demand, suit or recovery by
               any person or entity (i) arising in connection with this
               Agreement, (ii) arising out of Blockbuster's or any
               Blockbuster Entity's, or any such officer's, director's,
               employee's, consultant's or agent's performance of
               Blockbuster's obligations under this Agreement, including,

               Company or any Company Entity to perform the Company's
               obligations pursuant to this Agreement.  Notwithstanding the
               immediately preceding sentence the Company shall not be
               liable under the foregoing indemnification provision (x) to
               the extent any damage, loss, cost or expense is finally
               judicially

               determined to have resulted from the willful misconduct or
               gross negligence of Blockbuster, such Blockbuster Entity or
               such officer, director, employee, consultant or agent in the
               performance of its obligations under Section 1 hereof,  (y)
               to the extent any damage, loss, cost or expense arises out
               of a willful breach by Blockbuster of any of Blockbuster's
               obligations under this Agreement (other than its obligations
               under Section 1 hereof) or (z) for any damage, loss, cost or
               expense with respect to shareholder  litigation arising in

               consultants or agents may sustain or incur by reason of any
               claim, demand, suit or recovery by any person or entity
               arising out of Blockbuster's or any Blockbuster Entity's
               performance (or nonperformance) of Blockbuster's obligations
               pursuant to this Agreement but only (subject to 3(e) hereof)
               to the extent any damage, loss, cost or expense is finally
               judicially determined to have resulted from the willful
               misconduct or gross negligence of Blockbuster, any

                    (e)   Certain Liabilities.  The limitations on the

               liability of Blockbuster or a Blockbuster Entity contained

               apply to any breach by Viacom of its obligations or
               covenants under Section 17(b) or Section 18 hereof.

               SECTION 4.     Effective Date; Termination.
                              ---------------------------

                    (a)   Effective Date.  This Agreement shall not be
                          --------------
               effective until the date on which the transactions
               contemplated by both the Viacom Stock Purchase Agreement and
               the Block Party Acquisition (if not otherwise terminated in
               accordance with its terms) shall have been consummated;
               provided, however, that the Company's representations in
               --------  -------
               Section 22 hereof are true and complete, and the Company is
               in





                                          9

               compliance with the covenants of Section 22 hereof, on such
               date; provided, however, that Blockbuster, in its sole
                     --------  -------
               discretion, may waive the requirements of this sentence (but
               in no event earlier than the expiration or termination of
               the waiting period, if any, imposed by the Hart-Scott-Rodino
               Antitrust Improvements Act of 1976, as amended), in which
               case, this Agreement shall become effective on the date
               Blockbuster notifies the Company of such waiver.  The date
               on which this Agreement becomes effective pursuant to the
               preceding sentence is referred to herein as the "Effective
               Date".

                    (b)   Term.  The initial term of this Agreement shall
                          ----
               commence on the Effective Date and end on the fifth
               anniversary thereof.  Thereafter, this Agreement shall
               continue for consecutive one-year terms until it is
               terminated in accordance with this section.  This Agreement
               may be terminated by Blockbuster or the Company at the end
               of the initial term or any one-year renewal by written
               notice given to the other party not less than six months
               prior to such termination.  Notwithstanding the foregoing,
               (i) either the Company or Blockbuster may, at its option,
               terminate this Agreement upon two days' written notice to
               the other party, after June 30, 1995, if the Effective Date
               shall not have occurred on or prior to such date; (ii)
               either the Company or Blockbuster may, at its option,
               terminate this Agreement upon 60 days' written notice to the
               other party if (x) such other party has materially breached
               any of its obligations under this Agreement, (y) such notice
               specifies, in reasonable detail, the nature of such breach
               and (z) any breach specified in such notice has not been
               remedied or cured during the 60-day period following the
               delivery of such notice; provided, however, that if during
                                        --------  -------
               such 60-day period Blockbuster has undertaken good faith
               efforts toward remedying such breach, then such period shall
               be extended for a period equal to the lesser of (A) 120 days
               and (B) the amount of time in which such breach could
               reasonably be cured; and (iii) the provisions of Sections 3,
               15, 17(b) and 18 and the performances of the duties of
               subsections (b), (c) and (d) of this Section 4 shall survive
               any such termination.

                    (c)   Severance Payments.  The Company will pay to
                          ------------------
               Blockbuster all of the employee severance costs incurred and
               paid by Blockbuster or any Blockbuster Entity to employees
               or officers of Blockbuster or any Blockbuster Entity (which
               severance costs on average shall not materially exceed the
               average costs of severance payments paid to other similarly

          Agreement shall be waived, or be invalid or unenforceable, the
          remaining provisions of this Agreement shall be unaffected
          thereby and shall remain binding and in full force and effect,
          and in the case any provision is found to be invalid or
          unenforceable, each of the parties shall use its best efforts to
          find and employ an alternative means to achieve the same or
          substantially the same results as that contemplated by such
          provision.

          governed by, and be construed in accordance with, the laws of the
          State of Delaware applicable to contracts executed and to be
          performed entirely in that state.

               SECTION 12.    Submission to Jurisdiction.  Any legal action

          the jurisdiction of the aforesaid courts.

          Notwithstanding the prohibitions of the immediately preceding
          sentence, Blockbuster's and each Blockbuster Entity's
          confidentiality obligations shall exclude the following:  (i) any

          Blockbuster's knowledge, not in rightful possession of such
          information; (iii) information which is or becomes generally
          known in the pertinent trade or industry; (iv) such information

                                          12

          undertakings; or (v) such information is required to be disclosed
          by law, rule, regulation or judicial process (in which case
          Blockbuster shall, to the extent practicable, notify the Company
          prior to such disclosure).

               SECTION 16.    Assignment.  None of the parties hereto shall
                              ----------
          have the right (a) to assign, transfer or convey any of its

          v. Discovery Zone, Inc., et al., in the United States District
          Court for the Northern District of Illinois, or such action shall
          have been otherwise settled, and in all related actions, suits or
          other proceedings which may hereafter be filed or commenced
          (collectively, the "Securities Litigation"), take all actions
          (including causing its representatives on the Board of Directors
          of the Company to take all actions, subject to their fiduciary
          duties to the Company's stockholders) that are necessary to (i)
          cause there to be created a Special Litigation Committee of three
          members of the Board of Directors of the Company (the "Special
          Litigation Committee") having power (to the extent permitted by
          law) to supervise the conduct of the Securities Litigation and
          make recommendations to the Board with respect to material
          decisions with respect to the Securities Litigation, including
          settlements; provided that the Special Litigation Committee shall
                       --------
          have the power to enter into a settlement agreement pursuant to
          which the Company would not be obligated to pay any money and
          which settlement agreement does not contain any other terms or
          conditions which are adverse to the Company;  and (ii) cause
          Messrs. Flynn and Berrard (for so long as they are directors) and
          an Independent Director to be members of the Special Litigation
          Committee.

               (c)  For so long as Donald Flynn is a director of the
          Company, neither Blockbuster nor Viacom shall take any action to
          reduce the amount of directors and officers liability







                                          13

          insurance coverage for directors and officers of the Company
          below the amount in effect on the date of this Agreement.

               (d) The parties hereto agree that Section 17(b) and (c) are
          intended to be for the benefit of, and shall be specifically
          enforceable by, Donald Flynn.

               SECTION 18.    Viacom Covenants.  (a) Neither Viacom nor any
                              ----------------
          of its subsidiaries will, from and after the Effective Date and
          until the earlier of (i) the date that (w) directors, officers,
          employees or representatives of Viacom or any of its affiliates
          cease to constitute a majority of the Board of Directors of the
          Company and (x) Viacom beneficially owns less than 30% of the
          outstanding voting stock of the Company and (ii) the tenth
          anniversary of the date of this Agreement, engage in a
          transaction that would constitute a Rule 13e-3 (as such rule is
          in effect as of the date of this Agreement under the Exchange
          Act) transaction involving the Company, unless such transaction
          includes as a condition to the consummation of such transaction
          that  (A) if such transaction occurs prior to the second annual
          meeting of the stockholders of the Company occurring after the
          date of this Agreement, the holders of a majority of the shares
          of common stock of the Company not owned by Viacom or its
          subsidiaries that are present (whether in person or by proxy) and
          entitled to vote at the meeting of stockholders called to vote on
          such transaction shall have voted in favor thereof and (B) a
          special committee (the "Independent Committee") of the Board of
          Directors of the Company comprised solely of Independent
          Directors of the Company shall have (i) approved the terms and
          conditions of the transaction and (ii) received from its
          financial advisor a written opinion addressed to the Independent
          Committee substantially to the effect that the consideration to
          be received by the stockholders of the Company (other than Viacom
          or its subsidiaries) in the transaction is fair to such
          stockholders from a financial point of view.

               (b) The parties hereto agree that irreparable damage would
          occur in the event the provisions of Section 18(a) of this
          Agreement were not performed in accordance with their specific
          terms and that the parties shall be entitled to specific
          performance of the terms thereof, in addition to any other remedy
          at law or in equity.

               SECTION 19.    No Breach; Consents and Approvals.  (a) The
                              ---------------------------------
          execution and delivery of this Agreement by the Company do not,
          and the consummation of the transactions contemplated hereby will
          not (i) violate or conflict with the Certificate of Incorporation
          or the Bylaws of the Company or any of its subsidiaries or (ii)
          except as set forth on Schedule 19 attached hereto, constitute a
          breach or default (or an event that with notice or lapse of time
          or both would become a breach or default) of, or give rise to any
          lien, third party right of termination, cancellation, material
          modification or acceleration, under any material agreement,
          understanding or undertaking to which the Company or any of its

          any of its subsidiaries or (ii) constitute a breach or default
          (or an event that with notice or lapse of time or both would
          become a breach or default) of, or give rise to any lien, third
          party right of termination, cancellation, material modification
          or acceleration, under any material agreement, understanding or

TERM SHEET FOR REGISTRATION RIGHTS



    Demand Registration:     The holders of DZI Preferred Stock shall be
                             entitled to require DZI to file a registration
                             statement with respect to a public offering of
                             the DZI Common Stock for which their DZI Preferred
                             Stock is exercisable (the "Registrable
                             Securities") on one occasion; provided that no such
                             demand may be made within 180 days after the
                             effective date of any registration statement as to
                             which the holders could have exercised piggyback
                             registration rights as described below; and
                             provided further that such demand registration may
                             not be for a shelf registration of Registrable
                             Securities.  Such demand right may be exercised
                             by a majority of the DZI Common Stock for which
                             the DZI Preferred Stock is then exercisable that
                             are entitled to registration rights as provided
                             herein.  Any such registration shall be subject to
                             the piggyback registration rights granted to any
                             other person by DZI; provided that DZI shall not
                             grant any registration rights to any person after
                             the Effective Date that permit the cut-back by such
                             person of Registrable Securities included in a
                             demand registration thereof.


Limitations on Demand
Registration Rights:	     Any demand for registration will be required to
                             cover a number of Registrable Securities having a
                             fair market value of not less than $25,000,000 at
                             the time of such demand.  If a demand registration
                             is requested and prior to that time (i) DZI has in
                             good faith commenced the preparation of a
                             registration statement for an underwritten public
                             offering and (ii) the managing underwriter for such
                             offering determines, and set forth in writing to
                             the holders of the DZI Preferred Stock requesting
                             such registration (the "Participating Holders"),
                             its good faith opinion that the proposed offering
                             by the Participating Holders will materially and
                             adversely affect such DZI public offering,
                             DZI will be permitted to defer (a "Transactional
                             Deferral") the filing of such demand registration
                             on behalf of the Participating Holders until the
                             earliest of (a) the abandonment of such offering
                             by DZI, (b) 60 days after receipt by the
                             Participating Holders of the opinion of the
                             managing underwriter described above (unless the


                                       A-5




                             DZI offering has become effective on or prior to
                             such 60th day) or (c) if the DZI offering has
                             commenced on or prior to such 60th day, 90 days
                             after the effective date of such offering (or such
                             shorter period as may be requested by the
                             underwriter for such offering).  DZI will not be
                             permitted to defer a demand registration by the
                             Participating Holders on the basis of a
                             Transactional Deferral more than once in any
                             12-month period.  DZI may postpone for not more
                             than 90 days in any 365-day period the filing of a
                             demand registration on behalf of the Participating
                             Holders if DZI is  advised by legal counsel that
                             such filing will require disclosure of material
                             information that DZI has a bona fide business
                             reason for preserving as confidential and the
                             disclosure of which, DZI determines reasonably and
                             in good faith, would have a material adverse effect
                             on DZI.  If DZI defers any registration statement
                             as provided herein and the Participating Holders
                             determine not to proceed with such registration
                             on or prior to the end of such deferral
                             period, the holders' one registration demand will
                             be reinstated.


Piggyback Registration:	     If DZI proposes to register a primary or secondary
                             offering of its securities (except an Excluded
                             Registration, as hereinafter defined), any holder
                             of DZI Preferred Stock having registration rights
                             (a "Requesting Holder") will be entitled to include
                             Registrable Securities in such registration (which
                             Registrable Securities, in the case of a
                             registration to effect an underwritten offering,
                             shall include only Registrable Securities of the
                             same type as those being registered by the person
                             initiating such registration, if the managing
                             underwriter for such offering determines that the
                             inclusion of other types of Registrable Securities
                             would materially and adversely affect such
                             offering).  An "Excluded Registration" means (i)
                             any registration of DZI securities to be issued
                             pursuant to a stock option or employee benefit
                             plan, (ii) a registration of DZI securities
                             to be issued to or for the benefit of, or resold
                             by, the owners of one or more businesses,
                             franchises, development or management rights or
                             other assets to be acquired by DZI in
                             consideration, in whole or part, of such
                             securities, (iii) any registration in connection
                             with the issuance by DZI of (x) securities or
                             rights convertible into or exchangeable for
                             shares of DZI Common Stock having a conversion or
                             exchange premium at the time of initial offering of
                             such securities or rights of at least 10% in excess
                             of the then fair market value of the DZI Common
                             Stock or (y) warrants

                                       A-6





                             exercisable for shares of DZI Common Stock having
                             an exercise price at the time of the initial
                             offering of such warrants of at least 50% in excess
                             of the then fair market value of the DZI Common
                             Stock, and (iv) any registration effected pursuant
                             to the registration rights granted to McDonald's
                             Corporation.


Limitation on Participation
in DZI Registrations:	     The right to participate in a registration of
                             securities by DZI will be subject to customary
                             rights to cut-back the selling stockholder's
                             participation in an underwritten public offering
                             wherein the managing underwriter determines that
                             the number of shares that are proposed to be sold
                             would materially and adversely affect the offering.
                             If such cut-back rights are exercised in
                             connection with an underwritten offering, (i)
                             first, all securities DZI or the other person or
                             persons initiating such offering proposes to
                             sell for its own account shall be included and (ii)
                             second, Registrable Securities and securities
                             requested to be included by other holders of
                             registration rights from DZI shall be included pro
                             rata based on the number of shares of DZI Common
                             Stock held by each of them at the time the
                             registration statement is to be filed.


Expenses:	             In connection with any demand registration, DZI
                             will pay all out-of-pocket expenses of DZI incurred
                             in connection therewith, including registration and
                             filing fees, blue sky fees, printing expenses, and
                             fees and expenses of outside counsel and
                             independent auditors to DZI, so long as such
                             registration can be filed on Form S-3 and requires
                             no audit activities (other than the preparation
                             of a customary comfort letter) by DZI's independent
                             public accountants.  With respect to any other type
                             of demand registration, such expenses of DZI shall
                             be split 50/50.  DZI and the Participating Holders
                             shall each bear all of their own internal expenses
                             associated with any such offering.  The
                             Participating Holders will pay their pro rata share
                             of underwriting discounts, commissions, selling
                             concessions and stock transfer taxes applicable
                             to the sale by the holders of Registrable
                             Securities pursuant to a registration provided
                             for herein and all fees and disbursements of any
                             legal counsel, investment banker, accountant or
                             other professional advisor retained by a holder
                             ("Selling Expenses").  With respect to a piggyback
                             registration, DZI will pay all of the out-of-pocket
                             expenses of such

                                       A-7




                             registration, except the Requesting Holder's pro
                             rata share of Selling Expenses.


Underwriting:	             In connection with a demand registration involving
                             an underwritten public offering, DZ will, if
                             requested by the underwriters for such offering,
                             enter into an underwriting agreement with such
                             underwriters containing terms and  provisions
                             customarily contained in underwriting agreements
                             for secondary distributions, except contribution
                             provisions.  In connection with any piggyback
                             registration involving an underwritten offering,
                             the Company may require that all Registrable
                             Securities be included on the same terms and
                             conditions as shall be applicable to other
                             securities being sold by the underwriters in such
                             offering.


Other Provisions:	     If requested by the managing underwriter of a DZI
                             public offering, the holders of the DZI Preferred
                             Stock having registration rights will agree not to
                             sell any Registrable Securities or other DZI
                             Common Stock held by them, during the 30 days
                             prior to and the 90 days after the effectiveness
                             of the registration statement for such offering
                             (or such shorter period as requested by such
                             underwriter), except for sales as part of such
                             offering and private sales.  If requested by the
                             managing underwriter for the demand registration
                             contemplated hereby, DZI will agree not to sell
                             any DZI Common Stock, or securities exercisable or
                             exchangeable or convertible for DZI Common Stock,
                             subject to customary exceptions, for 90 days after
                             the effective date of the demand registration
                             statement.


Termination of Registration
Rights:	                     The registration rights granted hereunder will
                             terminate as to any Registrable Securities (and
                             such securities shall no longer constitute
                             "Registrable Securities"), the holder of
                             which can sell all Registrable Securities held by
                             such holder under Rule 144 under the Securities Act
                             of 1933, as amended, within a nine-month period.

                             registration rights to any transferee if at least
                             25% of the original number of shares of the DZI
                             Preferred Stock are being transferred.

                                 ARTICLE IV

                 Representations and Warranties of Sellers
                         Concerning the Transaction


     In order to induce Viacom to enter into this Agreement and to

consummate the transactions contemplated hereby, each Seller makes the

representations and warranties set forth below with respect to itself only,

each of which is independently relied upon by Viacom regardless of any

other investigation made or information obtained by Viacom, and each of

which is correct and complete as of the date of this Agreement and will be

correct and complete as of the Closing Date (as though made then and as

though the Closing Date were substituted for the date of this Agreement

throughout this Article IV).

     Section 4.1    Organization, Good Standing and Power of the Seller.

If such Seller is a corporation, such Seller is a corporation duly

organized, validly existing and in good standing under the laws of its

state of incorporation.  Such Seller has all requisite power and authority

to own, lease and operate its properties and to carry on its business as

now being conducted, and is duly qualified to do business and in good

standing in each jurisdiction in which the nature of its business or the

ownership or leasing of its properties makes such qualification necessary,

other than in such jurisdictions where the failure to so qualify would not

have a material adverse effect on such Seller or delay or prevent the

Seller from performing its obligations under this Agreement.  If a Seller

is a trust, such trust has been duly formed under the laws of the state of

its formation.

     Section 4.2    Authorization.  Such Seller has full power and

authority and legal capacity to enter into this Agreement and to perform

its obligations under this Agreement and to consummate the transactions

contemplated hereby.  The execution, delivery and performance of this

Agreement and all other agreements, instruments and documents contemplated

hereby to be executed by such




                                     5








Seller and the consummation of the transactions contemplated hereby have

been duly authorized by all necessary action of such Seller.  This

Agreement and all other agreements, instruments and documents contemplated

hereby to be executed by such Seller are (or upon execution and delivery

thereof by such Seller will be) valid and binding agreements of such

Seller, enforceable against such Seller in accordance with their respective

terms except (i) as the same may be limited by applicable bankruptcy,

insolvency, moratorium or similar laws of general application relating to

or affecting creditors' rights, including the effect of statutory or other

laws regarding fraudulent conveyances and preferential transfers, and (ii)

for the limitations imposed by general principles of equity (as opposed to

those principles applicable only to trusts).

     Section 4.3    No Breach.  The execution and delivery of this

Agreement by such Seller do not, and the consummation of the transactions

contemplated hereby will not, (i) violate or conflict with, in the case of

a corporate Seller, the certificate or articles of incorporation of such

Seller or the bylaws or code of regulations of such Seller or, in the case

of a Seller which is a trust, such Seller's trust agreement or applicable

law with respect to the obligations of a trustee or other fiduciary, or

(ii) constitute a breach or default (or an event that with notice or lapse

of time or both would become a breach or default) of, or give rise to any

lien, third party right of termination, cancellation, material modification

or acceleration, under any material agreement, understanding or undertaking

to which such Seller or, in the case of a corporate Seller, any of its

subsidiaries or shareholders or, in the case of a trust Seller, any of its

beneficiaries or trustees is a party or by which it or any of them is bound

or violate or conflict with any law, rule, regulation, judgment, decree or

order to which it or any of them is subject.  For purposes of this

Agreement, a "subsidiary" of any Seller shall mean any corporation,

partnership, joint venture, association or other entity, wherever and

however organized, in which such Seller owns directly or indirectly or has

the




                                     6







right to acquire a majority of the capital stock, equity or beneficial

interests, is a general partner, or otherwise controls management of, by

having the right or ability to designate a majority of the directors or

members of the governing body thereof, whether by agreement or otherwise.

     Section 4.4    Consents and Approvals.  Neither the execution and

delivery of this Agreement by each Seller nor the consummation of the

transactions contemplated hereby will require any consent, approval,

authorization or permit of, or filing with or notification to, any

governmental or regulatory authority, any court or tribunal or any other

person or entity, except (i) where the failure to obtain such consents,

approvals, authorizations or permits, or to make such filings or

notifications, would not prevent or delay such Seller from performing its

obligations under this Agreement; (ii) the filing of any reports or forms

required by "blue sky" regulations; (iii) filings required by the HSR Act;

(iv) the filing of reports required under the Securities Exchange Act of

1934, as amended (the "Exchange Act"); (v) filings required with the

National Association of Securities Dealers, Inc.; and (vi) filings required

to be made by Viacom or its affiliates.

     Section 4.5    The Shares.  At the Closing Date and upon the exercise

of certain warrants, each of the Sellers will own its Shares (and its

shares of Common Stock subject to Article XI (the "Additional Shares"))

free and clear of all liens, encumbrances, mortgages, pledges, security

interests, restrictions, prior assignments and claims of any kind or nature

whatsoever (collectively, "Liens").  The Shares (and Additional Shares)

owned by each Seller at Closing will have been duly and validly authorized

and issued, and will be fully paid and nonassessable and will not be

subject to any voting trust, stockholders agreement, proxies or other

agreements with respect to voting or transfer other than agreements to

which Viacom or its affiliates are a party.  The KFF Trust as Seller

represents and warrants that the sole trustee and the sole beneficiary of

such Seller is Kevin F. Flynn, and Kevin F. Flynn and Robert W. Flynn are

the sole members of the advisory committee




                                     7







of such Seller.  The BJF Trust as Seller represents and warrants that the

sole trustee and the sole beneficiary of such Seller is Brian J. Flynn, and

Brian J. Flynn and Robert W. Flynn are the sole members of the advisory

committee of such Seller.  The Shares owned by each Seller at Closing will

have been approved for trading on the Nasdaq National Market.

     Section 4.6    McDonald's Co-Sale Agreement.  The parties acknowledge

that Donald F. Flynn ("Flynn") and McDonald's Corporation ("McDonald's")

are parties to a Co-Sale Agreement dated as of August 30, 1994 (the "Co-

Sale Agreement") pursuant to which, among other things, Flynn has the

obligation to notify McDonald's not less than five business days prior to

the execution of a definitive agreement relating to the sale or transfer of

Common Stock by Flynn (the "Notice Provisions") and McDonald's has the

right to participate in such contemplated sale or transfer with respect to

the number of shares of Common Stock equal to the greater of (i) one-half

of the number of shares of Common Stock subject to the contemplated sale,

and (ii) the number of shares of Common Stock subject to the contemplated

sale multiplied by a fraction, the numerator of which is the aggregate

number of shares then beneficially owned by McDonald's and the denominator

of which is the sum of the aggregate number of shares then beneficially

owned by McDonald's and the aggregate number of shares then beneficially

owned by Flynn (which fraction as of the date of this Agreement is 67.06%).

Notwithstanding anything to the contrary elsewhere in this Agreement, the

failure by Flynn to comply with the Notice Provisions shall not be a breach

of any representation or warranty of the Sellers in this Agreement.  Viacom

acknowledges that McDonald's may decide to exercise its rights to

participate in the transactions contemplated by this Agreement in

accordance with the terms of the Co-Sale Agreement.

                                 ARTICLE V

          Representations and Warranties of Sellers Concerning DZI

     In order to induce Viacom to enter into this Agreement and to

consummate the transactions contemplated hereby, and subject to the

disclosure schedule attached hereto and incorporated herein by reference

(the "DZI Disclosure Schedule"), each Seller makes the representations and

warranties set forth below with respect to DZI, each of which is

independently relied upon by Viacom regardless of any other investigation

made or information obtained by Viacom (except as set forth in Section

5.11), and each of which is correct and complete as of the date of this

Agreement and will be correct and complete as of the Closing Date (as

though made then and as though the Closing Date were substituted for the

date of this Agreement throughout this Article V).  As used in this Article

V, "Knowledge of the Sellers" means the actual knowledge after reasonable

investigation of any of the Sellers or the Guarantors.  As used

hereinafter, the term "DZI Material Adverse Effect" shall mean a material

adverse effect on the assets, business, financial condition, or operations

of DZI and its subsidiaries considered as one enterprise.

     Section 5.1    Subsidiaries of DZI.  All subsidiaries of DZI are set

forth in Section 5.1 of the DZI Disclosure Schedule.  DZI owns the

percentage of capital stock or equity interest of each of the subsidiaries

set forth in said Section 5.1 free and clear, except as set forth in said

Section 5.1, of all Liens.  Except as set forth in Section 5.1 of the DZI

Disclosure Schedule and exclusive of the ownership of less than five

percent of the outstanding securities of any class registered under the

Exchange Act, neither DZI nor any of its subsidiaries owns, directly or

indirectly, of record or beneficially, any capital stock or equity interest

or investment in any corporation, partnership, joint venture, association

or other entity.




                                     9







     Section 5.2    Organization, Good Standing and Power of DZI and its

Subsidiaries.  DZI and each of its subsidiaries is a corporation or limited

partnership duly organized or formed, validly existing and in good standing

under the laws of its state of organization or formation.  DZI and each of

its subsidiaries has all requisite power and authority to own, lease and

operate its properties and to carry on its business as now being conducted,

and is duly qualified to do business and in good standing in each

jurisdiction in which the nature of its business or the ownership or

leasing of its properties makes such qualification necessary, other than in

such jurisdictions where the failure to so qualify would not have a DZI

Material Adverse Effect.

     Section 5.3    DZI Charter Documents, DZI Capital Structure.   The

Sellers have delivered or made available to Viacom true and complete copies

of the certificate of incorporation of DZI (the "Certificate of

Incorporation") and the bylaws, as amended, of DZI (the "Bylaws").  The

authorized capital stock of DZI consists of 260,000,000 shares, of which

250,000,000 are shares of Common Stock and 10,000,000 are shares of

preferred stock, par value $.01 per share (the "DZI Preferred Stock").  As

validly authorized and issued, fully paid, and nonassessable, and no shares

of DZI Preferred Stock were issued or outstanding.  Except for (i) an

aggregate of 4,025,990 shares of Common Stock issuable pursuant to

outstanding options under the Discovery Zone, Inc. 1993 Employee Stock

exercise of outstanding warrants issued to former partners of DKB

Investments, L.P. other than




                                     10







the Sellers, (iv) a maximum of 3,954,477 shares of DZI Common Stock as may

be issued by DZI upon conversion of its Liquid Yield Option Notes due 2013

(the "LYONS"), and such other shares of Common Stock as may be issued upon

the exercise by any holder of the LYONS of its rights to require DZI to

repurchase such LYONS, and (v) such shares of Common Stock as may be issued

by DZI in connection with pending acquisitions as set forth on Schedule

5.3, no other shares of common stock or DZI Preferred Stock or any rights,

agreements, or commitments of any kind obligating DZI to issue or sell any

other shares of Common Stock or DZI Preferred Stock were outstanding or

were authorized by DZI.  The number of the Outstanding Shares set forth in

the certificate to be delivered pursuant to Section 9.7 immediately prior

to the Closing will be correct as of the Closing.

     Section 5.4    No Breach; Consents and Approvals.  Neither the

execution and delivery of this Agreement by each Seller nor the execution

of the Management Services Agreement by the Company, nor the consummation

of the transactions contemplated hereby and thereby would, (i) violate or

conflict with the Certificate of Incorporation or the Bylaws of DZI or any

of its subsidiaries or (ii) except as set forth in Section 5.4 of the DZI

Disclosure Schedule, constitute a breach or default (or an event that with

notice or lapse of time or both would become a breach or default) of, or

give rise to any Lien, third party right of termination, cancellation,

material modification or acceleration, under any material agreement,

understanding or undertaking to which DZI or any of its subsidiaries is a

party or by which it or any of them is bound or violate or conflict with

any law, rule, regulation, judgment, decree or order to which it or any of

them is subject.  Except as set forth in Section 5.4 of the DZI Disclosure

Schedule, neither the execution and delivery of this Agreement by each

Seller nor the consummation of the transactions contemplated hereby will

require any consent, approval, authorization or permit of, or filing with

or notification




                                     11







to, any governmental or regulatory authority, any court or tribunal or any

other person or entity with respect to DZI or any of its subsidiaries,

except (i) where the failure to obtain such consents, approvals,

authorizations or permits, or to make such filings or notifications, would

not prevent or delay such Seller from performing its obligations under this

Agreement and would not have a DZI Material Adverse Effect, and (ii) the

filings specified in clauses (ii) through (vi) of Section 4.4.

     Section 5.5    SEC Documents.  The Sellers have delivered or made

available to Viacom a true and complete copy of each report, schedule,

registration statement and definitive proxy statement, including exhibits

filed therewith (but excluding exhibits incorporated therein by reference

and not attached thereto), filed by DZI with the Securities and Exchange

Commission ("SEC") since June 3, 1993 (the "SEC Documents"), which, to the

Knowledge of the Sellers, are all the documents (other than preliminary

materials) that DZI was required to file with the SEC since such date.

Except to the extent information contained therein has been revised or

superseded by a later filed SEC Document, as of their respective dates and

as of the date hereof, (i) none of the SEC Documents contained or contains

any untrue statement of a material fact or omits to state a material fact

required to be stated therein or necessary in order to make the statements

therein, in light of the circumstances under which they were made, not

misleading; and (ii) the financial statements of DZI included in the SEC

Documents comply as to form in all material respects with applicable

accounting requirements and the published rules and regulations of the SEC

with respect thereto, have been prepared in accordance with generally

accepted accounting principles during the periods presented (except as may

be indicated in the notes thereto or, in the case of the unaudited

statements, as permitted by Form 10-Q of the SEC) and fairly present

(subject, in the case of the unaudited statements, to normal, recurring

audit adjustments) the financial position of DZI and its




                                     12







consolidated subsidiaries as of the date thereof and the results of their

operations and their cash flows for the periods then ended.

     Section 5.6    Litigation.  Except as disclosed in the SEC Documents,

there is no suit, action or proceeding pending or, to the Knowledge of the

Sellers, threatened against or affecting DZI or any of its subsidiaries

that will have a DZI Material Adverse Effect, nor is there any judgment,

decree, injunction, rule or order of any governmental authority, court of

competent jurisdiction or arbitrator outstanding against DZI or any of its

subsidiaries having, or which in the future will have, a DZI Material

Adverse Effect.

     Section 5.7    Absence of Adverse Changes.  Except as disclosed in the

SEC Documents, since December 31, 1994, DZI and its subsidiaries have

conducted their respective businesses only in the ordinary course, and

there has not been (i) any damage, destruction or loss, whether covered by

insurance or not, which has or will have a DZI Material Adverse Effect, or

(ii) any transaction, commitment, dispute or other event or condition of

     (a)  (i) Each employee benefit plan, including but not limited to those

plans as defined in Section 3(3) of the Employee Retirement Income Security

Act of 1974, as amended ("ERISA"), maintained currently or in the past by

DZI or any of its subsidiaries, (ii) each employee benefit plan for which

DZI or any of its subsidiaries could incur liability under Section 4069 of

ERISA in the event such plan has been or were to be terminated and (iii)

is now and always has been operated and administered in accordance with all

applicable requirements of ERISA, the Internal Revenue Code of 1986, as

amended (the "Code") and the terms of such benefit plans, in all material

respects.  No legal action, suit or claim is pending or, to the Knowledge

of the Sellers, threatened with respect to any Benefit Plan and, to the

Knowledge of the Sellers, no fact or event exists that could give rise to

any such action, suit or claim.  The terms and conditions of each Benefit

Plan conform in all material respects with all applicable provisions of

ERISA and the Code.  Each Benefit Plan which is an employee pension benefit

plan, as defined in Section 3(2) of ERISA, and which is intended to be

"qualified" within the meaning of Section 401(a) of the Code ("Pension

Plan"), has been determined by the Internal Revenue Service to be so

qualified, and, to the Knowledge of the Sellers, no fact or event has

occurred since the date of such determination by the Internal Revenue

Service to adversely affect the qualified status of any such Benefit Plans.

tax arising under Section 4971, 4972, 4980, 4980B or 6652 of the Code or

Sellers, no fact or event exists which could give rise to any such

liability.  None of the Pension Plans which is subject to Title IV of ERISA

has completely or partially terminated, or been the subject of a reportable

event as defined in Section 4043 of ERISA.  No liability under or arising

out of or by operation of Subtitle D of Title IV of ERISA has been incurred

by DZI or any of its subsidiaries with respect to a Pension Plan and no

fact or event exists which would give rise to such liabilities.

     (c)  The aggregate amount of unfunded benefit liabilities under all

Pension Plans which are defined benefit pension plans did not, as of the

latest valuation date for such plans, exceed $1,000,000.  No Pension Plan

funding deficiency (whether or not waived) as defined in Section 412 of the

Code.

"Stockholder Transaction"), or (ii) a transfer to any affiliate of any such

Seller or Guarantor (provided that the restrictions of this Section 11.2

will continue to be applicable to the affiliate after such Transfer and

such affiliate shall assume such Seller's obligations under this Article XI

with respect to any Holdback Shares so transferred in writing).  For

purposes of this Section 11.2(a), the term "Holdback Period" shall mean the

period commencing on the date hereof and ending upon the earliest to occur

of (i) the termination of the Management Services Agreement in accordance

with its terms, (ii) the second anniversary of the date of this Agreement,

or (iii) a Transfer pursuant to a Stockholder Transaction.




                                     28









     (b)  The Sellers hereby jointly and severally grant to Viacom an

irrevocable option to purchase the number of Holdback Shares (up to a

maximum of 2,210,695 (subject to the Adjustments) shares of Common Stock)

necessary to increase Viacom's ownership interest in the outstanding shares

of Common Stock of DZI up to 49.99% (the "Top-Up Option").  The exercise

price per share (the "Exercise Price") of the Top-Up Option shall be equal

to 75% of the Average Closing Price (as defined below); provided that

notwithstanding anything to the contrary elsewhere herein, the exercise

price of the Top-Up Option shall never be less than $6.50 or more than

$12.50 per share.  The Top-Up Option shall be exercisable in whole or in

part at any time and from time to time during the Holdback Period, except

during a bona fide Stockholder Transaction of which Viacom has knowledge.

Upon the expiration of the Holdback Period, the Top-Up Option and all

rights and obligations relating thereto shall terminate.  For purposes of

this Section 11.2(b), the term "Average Closing Price" shall mean the

average closing price of the shares of Common Stock on the Nasdaq National

Market (or, if the Common Stock is not then traded on the Nasdaq National

Market, the composite closing price of the shares of Common Stock on the

securities exchanges on which the Common Stock may then be traded), as

reported in The Wall Street Journal (Midwest Edition), on the twenty

business days ending on the second business day before the date of the

Option Closing (as defined below) of any exercise of the Top-Up Option.

     (c)  In the event that Viacom elects to exercise all or any portion of

the Top-Up Option, Viacom shall give written notice of exercise to the

Sellers (the "Exercise Notice").  The closing of the purchase and sale of

the Holdback Shares pursuant to an exercise of the Top-Up Option (the

"Option Closing") shall occur at such place and time and on such date as

shall be specified by Viacom in the Exercise Notice; provided, however,

that the parties acknowledge that such Closing may be conducted by

facsimile, overnight courier, wire transfer or similar means; and provided,




                                     29







further, that in no event shall the Option Closing occur earlier than 10

days or later than 15 days after receipt of the Exercise Notice by the

Sellers.  At the Option Closing (i) Viacom shall pay to the Sellers the

aggregate Exercise Price for the number of Holdback Shares being purchased

as set forth in the applicable Exercise Notice by wire transfer of

immediately available funds, and (ii) the Sellers will deliver to Viacom a

stock certificate or stock certificates representing the shares of Common

Stock being purchased pursuant to the exercise of the Top-Up Option, duly

endorsed in blank or accompanied by stock powers executed in blank, in form

satisfactory to Viacom and with all required stock transfer tax stamps

affixed.

     (d)  In the event of any change in the outstanding shares of Common

Stock by reason of any stock dividend, stock split, reverse stock split,

recapitalization, combination, exchange of shares, merger, consolidation,

reorganization or the like or any other change in the corporate or capital

structure of DZI that would have the effect of altering any party's rights

or obligations under this Section 11.2, the number and kind of shares of

Common Stock or other securities of DZI subject to the first sentence of

this Section 11.2(a) and the Top-Up Option and the Exercise Price shall be

adjusted appropriately so as to restore each party to its rights hereunder.

     (e)  The parties hereto agree that irreparable damage would occur in

the event any provision of this Article XI is not performed in accordance

with the terms hereof and that Viacom shall be entitled to specific

performance of the terms hereof, in addition to any other remedy at law or

equity.

     Section 11.3    Right of First Offer.  (a) During the two-year period

commencing on the date of this Agreement, the Sellers jointly agree that

the Sellers will hold and will not directly or indirectly sell or otherwise

dispose of (a "Sale") an aggregate of 1,205,156 shares of Common Stock,

plus any Holdback Shares no longer subject to the provisions of Section

11.2 hereof




                                     30









(together, the "Held Shares"), except in compliance with this Section 11.3.

If at any time a Seller wishes to make a Sale of any of its Held Shares to

any Person, it shall deliver to Viacom by facsimile to the principal

offices of Blockbuster (Attention:  General Counsel) a written notice of

its desire to make such Sale (an "Offer Notice").  The Offer Notice shall

specify such Seller's desire to make such Sale (which shall be for cash

only), the number of Held Shares such Seller wishes to sell (the "Offered

Shares") and the cash price per Held Share at which, and any other terms

upon which, such Seller proposes to sell the Offered Shares (the "Offer

Terms").

     (b)  The receipt of an Offer Notice by Viacom from a Seller shall

constitute an offer by such Seller to sell to Viacom (or its affiliates)

the Offered Shares at the cash price and upon the other terms set forth in

the Offer Terms.  In the case of DKB during the "Restricted Period" (as

defined in the Co-Sale Agreement), such offer shall be irrevocable for five

business days after receipt of such Officer Notice by Viacom.  In the case

of DKB not during the Restricted Period and in the case of the KFF Trust

and the BJF Trust, such offer shall be irrevocable for three hours (if the

market value of the Offered Shares is equal to or less than $5,000,000) or

for 24 hours (if the market value of the Offered Shares is more than

$5,000,000) after receipt of such Offer Notice by Viacom (the respective

period during which the offer shall remain irrevocable is hereinafter

referred to as the "Waiting Period").  During the Waiting Period, Viacom

(or its affiliate) shall have the right to accept such offer as to all (but

not less than all) of the Offered Shares by giving a written notice of

acceptance (the "Notice of Acceptance") to such Seller prior to the

expiration of the Waiting Period.  If Viacom (or its affiliate) so accepts

a Seller's offer (an "Accepting Party"), such Person will purchase the

Offered Shares for cash from such Seller, at the cash price and upon the

other terms set forth in the Offer Terms.




                                     31







     (c)  The consummation of any such purchase by and sale to the

Accepting Party shall take place on such date, not later than five business

days after receipt of the Notice of Acceptance from the Accepting Party by

a Seller, as the Accepting Party and such Seller shall select.  Upon the

consummation of such purchase and sale, such Seller shall deliver to the

Accepting Party certificates evidencing the Offered Shares purchased and

sold duly endorsed in blank or accompanied by written instruments of

transfer in form reasonably satisfactory to the Accepting Party duly

executed by such Seller.

     (d)  In the event that (i) Viacom shall have received an Offer Notice

from a Seller but such Seller shall not have received from Viacom (or from

Viacom's affiliate) a Notice of Acceptance as to the Offered Shares prior

to the expiration of the Waiting Period following receipt of such Offer

Notice or (ii) the Accepting Party shall have given a Notice of Acceptance

to such Seller but shall have failed to consummate, other than as a result

of the fault of such Seller, a purchase of the Offered Shares with respect

to which such Notice of Acceptance was given within five business days

after receipt of the Notice of Acceptance by such Seller, then such Seller

may make a Sale of such Offered Shares so long as all the Offered Shares

are sold or otherwise disposed of (A) within 90 days after the date of

receipt of such Offer Notice by Viacom and (B) at, or in excess of, the

price and otherwise on terms no less favorable to the purchaser thereof

than the Offer Terms; provided, however, that in the case of subsection

(d)(ii) above, Viacom shall be responsible for the amount that the average

of the high and low prices of the Common Stock (as quoted in The Wall

Street Journal) on the fifth business day after receipt of the Notice of

Acceptance by such Seller is less than the bid price of the Common Stock at

the time of receipt of the Notice of Acceptance by such Seller.

                                ARTICLE XII

                              Indemnification

     Section 12.1   Agreement by the Sellers to Indemnify.

     (a)  Subject to the limitations contained in this Section 12.1, each

of the Sellers, jointly and severally agrees that such Seller will defend,

indemnify and hold Viacom and its respective affiliates harmless in respect

of the aggregate of all indemnifiable damages of Viacom.  For this purpose,

"indemnifiable damages" of Viacom means the aggregate of all expenses,

damages, losses, costs, deficiencies and liabilities (including related and

reasonable counsel fees and expenses, and compensatory and demonstrable

consequential damages) incurred or suffered by Viacom as a direct result of

(i) any inaccurate representation or warranty made by such Seller in or

pursuant to this Agreement, or (ii) any default in the performance of any

of the covenants or agreements made by such Seller in this Agreement;

provided, however, that any such expenses, damages, losses, costs,

deficiencies and liabilities resulting from any item or items relating to a

common set of facts or circumstances in connection with a breach of any

representation or warranty made herein shall not be considered

"indemnifiable damages" unless the amount involved is greater than $10,000;

provided, further, however that "indemnifiable damages" shall not include

any expenses, damages, losses, costs, deficiencies or liabilities incurred

as a result of any inaccuracy, breach or default of any provision of

Sections 5.10(A) or 5.10(B) hereof.

     (b)  Each of the representations and warranties made by the Sellers in

this Agreement shall survive until and including the first anniversary of

the Closing Date, and thereafter all such representations and warranties

shall be extinguished; provided, however, the representations and

warranties made by the Sellers in Article IV hereof shall in each case

survive forever, the representations and warranties made by the Sellers in

Section 5.8 shall survive for the applicable




                                     33







statute of limitations period, except to the extent that other

representations and warranties in this Agreement reference compliance with

specific laws, regulations or orders, which such representations and

warranties shall survive until and including the first anniversary of the

Closing Date, the representations and warranties made by the Sellers in

Section 5.9 shall survive for a period of seven years and six months from

the Closing Date, and the representations and warranties made by the

Sellers in Sections 5.10(A) or 5.10(B) shall survive through the Closing.

No claim for the recovery of indemnifiable damages based upon the

inaccuracy of such representations and warranties may be asserted by Viacom

after such representations and warranties shall be thus extinguished;

provided, however, that claims first asserted within the applicable period

(whether or not the amount of any such claim has become ascertainable

within such period) shall not thereafter be barred.

     (c)  The Sellers shall only be liable for any claim for indemnifiable

damages arising out of any inaccuracy of any representation or warranty

contained in Article V hereof if the aggregate amount of all such

indemnifiable damages payable by all Sellers exceeds $500,000, in which

case the Sellers shall be liable for all indemnifiable damages arising out

of such inaccuracies, including the first $500,000.  No Seller shall be

liable for any claim for indemnifiable damages arising out of the

inaccuracy of any representation and warranty or the default in the

performance of any covenant or agreement made by any other Seller as to

itself only.  The aggregate amount of indemnifiable damages payable by any

Seller shall not exceed such Seller's share of the Purchase Price.

     (d)  The remedies provided for in this Section 12.1 shall be the sole

monetary remedy available to Viacom under this Agreement, and there shall

be no remedy (other than with respect to Section 9.1 hereof) available to

Viacom under this Agreement for any inaccuracy, breach or default of any

provisions of Sections 5.10(A) and 5.10(B) hereof.

     Section 12.2   Agreement by Viacom to Indemnify.




                                     34







     (a)  Subject to the limitations contained in this Section 12.2, Viacom

agrees that it will defend, indemnify and hold the Sellers and their

respective affiliates harmless in respect of the aggregate of all

indemnifiable damages of the Sellers.  For this purpose, "indemnifiable

damages" of the Sellers means the aggregate of all expenses, losses, costs,

deficiencies, liabilities and damages (including related and reasonable

counsel fees and expenses, and compensatory and demonstrable consequential

damages) incurred or suffered by the Sellers as a direct result of any (i)

inaccurate representation or warranty made by Viacom in or pursuant to this

Agreement, or (ii) default in the performance of any of the covenants or

agreements made by Viacom in this Agreement; provided, however, that any

such expenses, damages, losses, costs, deficiencies and liabilities

resulting from any item or items relating to a common set of facts or

circumstances in connection with a breach of any representation or warranty

made herein shall not be considered "indemnifiable damages" unless the

amount involved is greater than $10,000.

     (b)  Each of the representations and warranties made by Viacom in this

Agreement shall survive forever.

     (c)  Viacom shall be liable only for any claim for indemnifiable

damages arising out of any inaccuracy of any representation or warranty if

the aggregate amount of all such indemnifiable damages exceeds $500,000, in

which case Viacom shall be liable for all indemnifiable damages arising out

of such inaccuracies, including the first $500,000.  The aggregate amount

of indemnifiable damages payable by Viacom to all Sellers shall not exceed

the Purchase Price.

     (d)  The remedies provided for in this Section 12.2 shall be the sole

monetary remedy available to the Sellers under this Agreement or otherwise.

     Section 12.3   Indemnification Procedures for Third Party Claims.  In

the event that subsequent to the Closing Date any claim is asserted by a

third party against a party hereto as to




                                     35







which such party is entitled to indemnification hereunder, such party (the

"indemnified party") shall as promptly as possible notify the party

obligated to indemnify it (the "indemnifying party") thereof in writing.

No delay on the part of the indemnified party to notify the indemnifying

party of a claim shall relieve any obligation of the indemnifying party to

indemnify the indemnified party with respect to such claim unless (and then

solely to the extent) the indemnifying party is prejudiced in its ability

to defend against the subject claim by the delay in such notification.  The

indemnifying party shall have the right, upon written notice to the

indemnified party within ten (10) days after receipt from the indemnified

party of notice of such claim, to conduct at its expense and with counsel

of its choice reasonably satisfactory to the indemnified party the defense

against such claim in its own name, or, if necessary, in the name of the

indemnified party.  In the event that the indemnifying party shall fail to

give such notice, it shall be deemed to have elected not to conduct the

defense of the subject claim, and in such event the indemnified party shall

have the right to conduct such defense and to compromise and settle the

claim without prior consent of the indemnifying party, and the indemnifying

party will remain responsible for all indemnifiable damages suffered by the

indemnified party relating to the subject claim.  In the event that the

indemnifying party does elect to conduct the defense of the subject claim,

the indemnified party will cooperate with and make available to the

indemnifying party such assistance and materials as may be reasonably

requested by it, all at the expense of the indemnifying party, and the

indemnified party shall have the right at its expense to participate in the

defense, provided that the indemnified party shall have the right to

compromise and settle the claim only with the prior written consent of the

indemnifying party (such consent not to be unreasonably withheld).  The

indemnifying party will not consent to the entry of any judgment with

respect to a subject claim or enter into any settlement with respect

thereto which does not include a provision whereby the plaintiff or

claimant




                                     36







releases the indemnified party from all liability with respect thereto or

in cases involving equitable relief, puts the indemnified party in the same

position as it was prior to the initiation of the claim, without the prior

written consent of the indemnified party (such consent not to be

unreasonably withheld so long as such settlement or judgment only involves

the payment of money damages).

     Section 12.4   Credit Provisions.  In the event that, notwithstanding

the limitations contained in this Article XII, an indemnifying party

nevertheless becomes liable to an indemnified party hereunder, the

indemnifying party shall be entitled to a credit or offset against any such

liability of an amount equal to the value of any net tax benefit realized

by the indemnified party in connection with the loss or damage suffered by

the indemnified party which forms the basis of the indemnifying party's

liability hereunder and the receipt of the indemnification payment by the

indemnified party.



                                ARTICLE XIII

     Section 13.1   [Intentionally omitted.]

     Section 13.2   Brokers' Commission.  Each Seller will indemnify and

hold harmless Viacom from the commission, fee or claim of any person, firm

or corporation employed or retained or claiming to be employed or retained

by such Seller to bring about, or to represent it in, the transactions

contemplated hereby.  Viacom will indemnify and hold harmless each of the

Sellers from the commission, fee or claim of any person, firm or

corporation employed or retained or claiming to be employed or retained by

Viacom to bring about, or to represent it in, the transactions contemplated

hereby.

     Section 13.3   Amendment and Modification.  The parties hereto may

amend, modify and supplement this Agreement in such manner as may be agreed

     Section 13.4   Binding Effect.  This Agreement shall be binding upon

and inure to the benefit of the parties hereto and their respective

successors, assignees, heirs and legal representatives.  Nothing in this

Agreement shall confer upon any person, firm or corporation not a party to

this Agreement, or the legal representatives of such person, firm or

corporation, any rights or remedies of any nature or kind whatsoever by

reason of this Agreement.

     Section 13.5   Entire Agreement.  This Agreement, the DZI Disclosure

Holdback Shares and the other transactions contemplated herein and

supersede all prior understandings and agreements of the parties with

respect to the subject matter hereof.

     at any time prior to the Closing Date;

         (ii)  by the Sellers in the event of the material breach by Viacom

     of any provision of this Agreement (it being agreed that if the breach

     in question is a breach by Viacom of any representation or warranty

     contained in Article VI of this Agreement, such breach will not be

     breach is not remedied by Viacom within 30 days after receipt of

     notice thereof from the Sellers;

        (iii)  by Viacom in the event of the material breach by any of the

     Sellers of any provision of this Agreement (it being agreed that if

Discovery Zone, Inc.
205 North Michigan Avenue
Suite 3400
Chicago, IL 60601
Attn: Donald F. Flynn


Gentlemen:

          This letter sets forth our agreement with respect to the purchase
from Blockbuster Family Fun, Inc., a Delaware corporation (the "Seller"),
of certain assets, properties and businesses of the Seller by Discovery
Zone, Inc., a Delaware corporation (the "Purchaser"), for the consideration
set forth herein. Such assets, properties and businesses (the "Center
Assets") pertain to the ownership and operation of two (2) family
entertainment centers operating under the name and mark "Block Party" (the
"Centers"), the addresses of which are set forth on Exhibit A attached
hereto. The parties hereto agree and acknowledge that subject to
satisfaction or waiver of the conditions to closing specified in Paragraph
3 below, this letter constitutes an obligation binding on the parties
hereto.


          1.   Purchase Price. The purchase price for the Center Assets
               --------------
     will be an amount equal to the lesser of (i) out-of-pocket expenses
     incurred in the development and operation of the Centers and
     (ii) $15,000,000.00 (the "Original Principal Balance")
     payable by the delivery of a promissory note (the "Note") of the
     Purchaser dated the date upon which the transactions contemplated
     hereby are consummated. The Note will have a term of ten (10) years
     and will accrue interest at a variable rate equal to LIBOR plus .75%.
                                                                ----
     For purposes of this letter, "LIBOR" means the rate per annum (rounded
     upwards, if necessary to the next higher one hundred-thousandth of a
     percentage point) for deposits in United States dollars for a one-
     month period, which appears on the display designated at Page 3570 on
     the Telerate Service (or such other page as may replace Page 3750 on
     that service or such other service as may be nominated by the British
     Bankers' Association as the information vendor for the purposes of
     displaying British Bankers' Association Interest Settlement Rates for
     United States dollar deposits) and as adjusted on the first day of
     each calendar month following the Closing Date (as hereinafter
     defined)

     (or if such day is not a day on which such rate is quoted, the next
     succeeding day on which such rate is quoted). Interest accruing on the
     then-outstanding principal balance of the Note will be due and payable
     in arrears on the first day of each August, November, February and May
     following the Closing Date (each, an "Interest Payment Date").
     Commencing on the third anniversary of the Closing Date, the Purchaser
     shall pay to the Seller on each Interest Payment Date an amount equal
     to the interest accruing on the Note plus the following amounts,
                                          ----
     which amounts will be payable in four (4) equal installments on each
     Interest Payment Date during any such year:

               (a) During Year 4, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 7 and the denominator of which is 28;

               (b) During Year 5, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 6 and the denominator of which is 28;

               (c) During Year 6, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 5 and the denominator of which is 28;

               (d) During Year 7, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 4 and the denominator of which is 28;

               (e) During Year 8, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 3 and the denominator of which is 28;

               (f) During Year 9, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 2 and the denominator of which is 28; and

               (g) During Year 10, the result obtained by multiplying the
          Original Principal Balance by a fraction, the numerator of which
          is 1 and the denominator of which is 28.

     The Seller will have the right to prepay the Note in whole or in part
     from time-to-time without penalty. The Purchaser will assume
     liabilities of the Seller under real property and personal property
     leases related to the operation of the Centers (the "Assumed
     Liabilities"). Taxes (to the extent prepaid) and real estate rentals
     will be prorated as of the Closing Date.


          2.   The Closing. The closing (the "Closing") of the purchase and
               -----------
     sale of the Center Assets will occur on the third business day
     following satisfaction or waiver of the conditions to closing set
     forth in Paragraph 3 (such day of Closing being hereinafter referred
     to as the "Closing Date").


          3.   Definitive Agreements. The Purchaser and the Seller will
               ---------------------
     negotiate in good faith one or more definitive agreements concerning
     the purchase and sale of the Center Assets (the "Center Definitive
     Agreement(s)"). The Purchaser and Blockbuster Entertainment Group, a
     division of Viacom Inc. ("Blockbuster") will cooperate with each other
     in the event Blockbuster determines it shall receive certain tax
     benefits by structuring the transaction as a sale of all outstanding
     capital stock (the "Stock Sale") of the Seller to the Purchaser
     followed by an election by the Purchaser under Section 338(h)(10) of
     the Internal Revenue Code of 1986, as amended. In the event of a Stock
     Sale, the transaction will be structured to the extent possible to
     mirror the economics, representations, warranties, covenants and
     conditions to closing of the Center Definitive Agreement(s) and
     Blockbuster will indemnify the Purchaser and hold it harmless for all
     liabilities other than the Assumed Liabilities. The Center Definitive
     Agreement(s) will contain representations, warranties and covenants
     substantially identical to those found in that certain Agreement and
     Plan of Merger (the "Merger Agreement"), dated as of September 2,
     1994, by and among the Purchaser, Columbus Acquisition, Inc.,
     Blockbuster Entertainment Corporation and Blockbuster Children's
     Amusement Corporation; provided, however, that such representations,
                            -----------------
     warranties and covenants may be revised only to reflect the differing
     transaction structures. The Center Definitive Agreement(s) will also
     contain indemnification provisions substantially identical to those
     contained in the Merger Agreement; provided, however, that the baskets
                                        -----------------
     set forth in Sections 11.1 and 11.2 of the Merger Agreement will be
     reduced proportionally based upon the difference in consideration
     between the Merger

     Agreement and the Center Definitive Agreement(s). The Center
     Definitive Agreement(s) will contain conditions to closing
     substantially identical to those contained in that certain Stock
     Purchase Agreement (the "Purchase Agreement"), dated as of the date
     hereof, among DKB, Inc., Kevin F. Flynn June, 1992 Non-Exempt Trust,
     Brian J. Flynn June, 1992 Non-Exempt Trust, Donald F. Flynn, Kevin F.
     Flynn, Brian J. Flynn, Viacom Inc. and Blockbuster Discovery
     Investment, Inc.; provided, however, that such conditions to closing
                       -----------------
     may be revised only to reflect the differing transaction structures.
     Notwithstanding anything to the contrary herein, the Center Definitive
     Agreement(s) will also contain conditions for a limited due diligence
     review by the Purchaser to be completed by the close of business on
     April 21, 1995, which review will be deemed satisfactory unless it
     reveals (i) a material misstatement in the balance sheets or profit
     and loss statements previously delivered to the Purchaser, (ii) a
     material agreement or contract entered into by the Purchaser is not
     enforceable, or (iii) the Purchaser does not have good title to a
     material asset which it otherwise claims to own free and clear of any
     liens or encumbrances (the "Materiality Conditions"). For a
     Materiality Condition to prevent Closing, the Seller must have first
     been given a reasonable opportunity not longer than ten (10) business
     days to cure such Materiality Condition. In the event there is a
     Materiality Condition that is not cured as provided herein, the
     parties agree, without prejudice to the rights of the Purchaser to
     terminate this agreement, to discuss in good faith a reduction of the
     Original Principal Balance. The Center Definitive Agreement(s) will
     provide for a six-month royalty-free license from Blockbuster
     Entertainment Inc. to the Purchaser of the mark "Block Party".


          4.   Access to Information. Promptly following execution of this
               ---------------------
     agreement in principle, the Seller will provide the Purchaser, its
     officers, directors, employees, agents and representatives with access
     to all information concerning the Centers and all officers of the
     Seller (at reasonable times and with reasonable advance notice) in
     order to permit the Purchaser to perform a thorough legal, financial
     and business investigation of the Centers.


     5.   Confidentiality. Each of the Purchaser, the Seller and FEC agrees
          ---------------
     that it will not, and will use its best efforts to cause its officers,
     directors, employees, affiliates, agents and representatives not to,
     disclose the subject matter or terms of this agreement in principle or
     any confidential information exchanged in connection

     therewith, or issue any news release or make any other public
     statement with respect thereto, without the prior written consent of
     the other parties hereto, except as required by law, rule, regulation
     or judicial process (in which case the party required to disclose such
     information shall, to the extent practicable, notify the other parties
     prior to such disclosure).


          6.   Expenses. Whether the transactions contemplated hereby are
               --------
     consummated, each of the parties hereto will bear its own expenses
     (including attorneys fees and expenses) in connection with the
     negotiation and execution of the Center Definitive Agreement(s) and
     the consummation of the transactions contemplated thereby.


          7.   Governing Law. This agreement in principle will be governed
               -------------
     by and construed in accordance with the laws of the State of Delaware.


          8.   Termination. This agreement will terminate on the earlier to
               -----------
     occur of (i) the date of closing of the transactions contemplated by
     the Purchase Agreement or (ii) June 30, 1995, without liability or
     obligation on the part of any party hereto other than for a breach of
     the provisions of the first sentence of Paragraph 3 and Paragraphs 5
     and 6; provided, however, that this agreement may be terminated by the
            -----------------
     mutual agreement of the parties hereto.

                     VIACOM ENTERS INTO MANAGEMENT AGREEMENT WITH
                                    DISCOVERY ZONE



                      CHICAGO, April  17 --  Discovery Zone  Inc. (NASDAQ:

            ZONE) today announced that the Blockbuster Entertainment Group

            of Viacom, Inc. (AMEX:   VIA, VIA.B) has entered into  a five-

            year Management Services Agreement with Discovery Zone.



                      The Company  said that  Discovery Zone Chairman  and

            CEO Donald F. Flynn  will remain chairman and a  member of the

            board of directors, and Steven R. Berrard, president and chief

            executive officer of  Blockbuster has been elected  as interim

            Discovery Zone chief  executive until a replacement  is named.

            Discovery Zone board  members not affiliated with  Viacom will

            resign effective at closing.



                      Discovery Zone also announced  that the Flynn family

            will complete the previously announced exercise of outstanding

            warrants to acquire additional shares of Discovery Zone common

            stock, investing  $26,700,000.  Blockbuster  Entertainment, in

            order  to retain its 49.9 percent  ownership of Discovery Zone

            common stock, will  purchase an aggregate of  3,823,647 shares

            of Discovery Zone common stock from the Flynn family.



                      "This management  agreement is a major  milestone in

            the  growth  and  evolution of  Discovery  Zone,"  said Flynn.

            "Viacom's  wealth of brands and Blockbuster's expertise as one

            of  the  premier  entertainment retailers  in  the  world will

            enrich  the overall  experience  in  all  of  our  FunCenters.

            Additionally, Viacom's infrastructure and strong position in

            the  entertainment  industry  should lead  to  a  reduction in

            operating  expenses  and additional  marketing  opportunities,

            while  the  grant  of the  warrants  will  give  Viacom strong

            incentives to enhance shareholder value."







                      "We  have had  a long, successful  relationship with

            Discovery Zone as  a shareholder, former franchisee  and joint

            venture partner," said Berrard.  "Don Flynn and Discovery Zone

            Management  have  pioneered  the  concept  of  the  children's

            FunCenter  and  established  the  Company  as  the  nationally

            recognized    leader    in     children's    destination-based

            entertainment.   Now, with  this management agreement  we will

            have the opportunity to build on its success, further leverage

            our  assets, improve the Company's operations and increase its

            profitability."



                      The Management Services  Agreement is for a  term of

            five  years, with successive  one-year extensions.   Under the

            Management   Agreement,   Discovery    Zone   will   reimburse

            Blockbuster  for  its   costs  incurred  and  will   grant  to

            Blockbuster warrants to acquire an aggregate  of up to 473,463

            shares  of   a  new  class  of   non-cumulative,  convertible,

            participating preferred  stock.   The terms  of the  agreement

            have  been approved by  an independent committee  of Discovery

            Zone's Board of Directors.



                      Each  share of  preferred stock will  be convertible

            into 24  shares of Discovery  Zone common stock by  any holder

            who is not affiliated with Blockbuster.  The warrants, a Class

            A Warrant, a  Class B Warrant and  a Class C Warrant,  will be

            exercisable for an  equal number of shares of  preferred stock

            and will vest on the  first, second and third anniversaries of

            the  effective date of the management agreement, with exercise

            prices per share of preferred  stock of $249.000, $286.344 and

            $343.608, respectively.



                      Blockbuster  also   will  sell  its   "Block  Party"

            entertainment centers  to Discovery Zone for net book value of

            $15 million payable in subordinated notes.



                      It is anticipated that these transactions, which are

            subject to customary closing  conditions, will close  sometime

            during the second quarter.
