                                OPTION AGREEMENT

         OPTION AGREEMENT dated as of February 21, 1998, between ACTV, Inc., a
Delaware corporation (the "Corporation") and Bruce J. Crowley (the "Employee").

         The Corporation desires to grant to the Employee the right and option
to purchase up to 633,000 shares (the "Option Shares") of Common Stock (the
"Common Stock"), of the Corporation, on the terms and subject to the conditions
hereinafter set forth.

         NOW, THEREFORE, in consideration of the receipt of $1.00 and other good
and valuable consideration, the receipt of which is hereby acknowledged, the
parties hereby agree as follows:

         SECTION 1. OPTION TO PURCHASE COMMON STOCK.

                  a. Subject to Section 5 hereof, the Corporation hereby grants
to the Employee an option (the "Option") to purchase from the Corporation
633,000 Option Shares, at a purchase price of $1.60 per Option Share (the
"Option Price"). The Employee's right and option to purchase the Option Shares
shall vest annually com-mencing January 1, 2000 to and including January 1,
2002, in three annual installments of 211,000 Option Shares at the Option Price,
so long as the Employee is employed by the Corporation. Said right shall be
cumulative so that as of January 1, 2002, the Employee shall have the fully
vested right to purchase 633,000 Option Shares. In the event that the Employee's
employment with the Corporation terminates prior to any January 1 of any year,
the Employee shall not have the right or option to purchase any part of the
respective installment of 211,000 Option Shares that would have otherwise vested
on or after that particular January 1. With respect to the Option, the "Option
Period" shall commence on the date hereof and terminate on December 31, 2006.

                  b. The Option may be exercised by the Employee by delivery to
the Corporation, at any time commencing one year from the date hereof, of a
written notice (the "Option Notice"), which Option Notice shall state the
Employee's intention to exercise the Option, the date on which the Employee
proposes to purchase the Option Shares (the "Closing Date") and the number of
Option Shares to be purchased on the Closing Date, which Closing Date shall be
no later than 30 days nor earlier than 10 days following the date of the Option
Notice. Upon receipt by the Corporation of an Option Notice from the Employee,
the Employee shall be obligated to purchase that number of Option Shares to be
purchased on the Closing Date set forth in the Option Notice.

<PAGE>

                  c. The purchase and sale of Option Shares acquired pursuant to
the terms of this Option Agreement shall be made on the Closing Date at the
offices of the Corporation. Delivery of the Stock certificate or other
instrument registered in the name of the Employee, evidencing the Option Shares
being purchased on the Closing Date, shall be made by the Corporation to the
holder of this Option on the Closing Date against the delivery to the
Corporation of a check in the full amount of the aggregate purchase price
therefor.

         SECTION 2. REPRESENTATIONS AND WARRANTIES OF THE HOLDER. The Employee
hereby represents and warrants to the Corporation that in the event the Employee
acquires any Option Shares, such Option Shares will be acquired for his own
account, for investment and not with a view to the distribution thereof. The
Employee understands that except as set forth in Section 6 hereof, the Option
Shares will not be registered under the Securities Act of 1933, as amended (the
"Securities Act"), by reason of their issuance in a transaction exempt from the
registration requirements of the Securities Act pursuant to Section 4 (2)
thereof and that they must be held indefinitely unless a subsequent disposition
thereof is registered under the Securities Act or the transaction is except from
registration.

         SECTION 3. REORGANIZATION; MERGERS; SALES; ETC. If, at any time during
the Option Period, there shall be any capital reorganization, reclassification
of Common Stock (other than a change in par value or from par value to nor par
value or from no par value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares), the consolidation or merger of
the Corporation with or into another corporation or of the sale of all or
substantially all the properties and assets of the Corporation as an entirety to
any other corporation or person, the unexercised and fully vested portion of
this Option shall, after such reorganization, reclassification, consolidation,
merger or sale, be exercisable for the kind and number of shares of stock or
other securities or property of the Corporation or of the corporation resulting
from such consolidation or surviving such merger or to which such properties and
assets shall have been sold to which the Employee would have been entitled if
the Employee had held shares of Common Stock issuable upon the exercise hereof
immediately prior to such reorganization, reclassification, consolidation,
merger or sale. The provisions of this Section 3 shall similarly apply to
successive reorganizations, reclassifications, consolidations, mergers and
sales.

         SECTION 4. ADJUSTMENT OF OPTION SHARES AND OPTION PRICE.

                  a. The number of Option Shares subject to this Option during
the Option Period shall be cumulative as to all prior dates of calculation and
shall be adjusted for any stock dividend, subdivision, split-up or combination
of Common Stock.

<PAGE>

                  b. If, at any time through December 31, 2001 of the Option
Period, the Corporation issues any previously unissued Common Stock over and
beyond the number of shares outstanding February 21, 1998, then the number of
shares subject to the Option shall be adjusted such that the holder thereof
shall have the right to exercise the Option for the same percentage of the
issued and outstanding Common Stock of the Corporation as he held option shares
on February 21, 1998.

                  c. The Option Price shall be subject to adjustment from time
to time as follows:

                           (1) If, at any time during the Option Period, the
number of shares of Common Stock outstanding is increased by a stock dividend
payable in shares of Common Stock or by a subdivision or split-up of shares of
Common Stock, then, immediately following the record date fixed for the
determination of holders of shares of Common Stock entitled to receive such
stock dividend, subdivision or split-up, the Option Price shall be appropriately
decreased so that the number of shares of Common Stock issuable upon the
exercise hereof shall be increased in proportion to such increase in outstanding
shares.

                           (2) If, at any time during the Option Period, the
number of shares of Common Stock outstanding is decreased by a combination of
outstanding shares of Common Stock, then, immediately following the record date
for such combination, the Option Price shall be appropriately increased so that
the number of shares of Common Stock issuable upon the exercise hereof shall be
decreased in proportion to such decrease in outstanding shares.

         SECTION 5. TERMINATION OF THE OPTIONS.

                  a. TERMINATION OF OPTIONS IN GENERAL. Subject to subsections
(b) - (c) of this Section, the Option granted hereby shall terminate and the
Option shall no longer be exercisable after the earlier of December 31, 2006 or
one year after the date of termination of employment, except in the case of
death or disability.

                  b. OPTION RIGHTS UPON DISABILITY. If an Employee becomes
disabled while employed by the Corporation or any affiliate or subsidiary, the
Board of Directors or the Stock Option Committee of the Corporation, will allow
the Option to be fully exercised, to the extent that the Employee was entitled
to exercise the Option at the date of his disability.

                  c. DEATH OF EMPLOYEE. In the event that an Employee shall die
while he is an employee of the Corporation and prior to his complete exercise of
the Option, the Option may be exercised in whole or in part only: (i) by the
Employee's estate or on behalf of such person or persons to whom the Employee's
rights pass under

                                       3
<PAGE>

his Will or by the laws of descent and distribution, (ii) to the extent that the
Employee was entitled to exercise the Option at the date of his death, and (iii)
prior to the expiration of the term of the Option.

         SECTION 6. PIGGYBACK REGISTRATION.

                  a. If, at any time commencing January 1, 2000 and expiring
December 31, 2006, the Corporation proposes to register any of its securities
under the Securities Act (other than in connection with a merger or pursuant to
Form S-8 or other comparable Form) it will give written notice by registered
mail, at least thirty (30) days prior to the filing of such registration
statement, to the Employee of its intention to do so. If the Employee notifies
the Corporation within ten (10) days after receipt of any such notice of his
desire to include any Option Shares, owned by him (on a fully vested basis) in
such proposed registration statement, the Corporation shall afford the Employee
the opportunity to have any of his Option Shares registered under such
registration statement, the Corporation shall afford the Employee the
opportunity to have any of his Option Shares registered under such registration
statement; provided that (i) such inclusion does not pose any significant legal
problem and (ii) if such registration statement is filed pursuant to an
underwritten public offering, the underwriter approves such inclusion.

                  b. Notwithstanding the provisions of this Section 6, the
Corporation shall have the right at any time after it shall have given written
notice pursuant to this Section 6 (irrespective of whether a written request for
inclusion of any Option Shares shall have been made) to elect not to file any
such proposed registration statement, or to withdraw the same after the filing
but prior to the effective date thereof.

                  c. Employee will cooperate with the Corporation in all
respects in connection with this Agreement, including, timely supplying all
information reasonably requested by the Corporation and executing and returning
all documents reasonably requested in connection with the registration and sale
of the Option Shares. In addition, Employee will comply with all applicable
provisions of state and federal securities laws, including rule 10b-6 and will
not, during the course of a distribution, purchase any of the securities being
distributed.

                  d. All expenses incurred in any registration of the Option
Shares under this Agreement shall be paid by the Corporation, including, without
limitation, printing expenses, fees and disbursements of counsel for the
Corporation, expenses of any audits to which the Corporation shall agree or
which shall be necessary to comply with governmental requirements in connection
with any such registration, all registration and filing fees for the Option
Shares under federal and state securities laws, and expenses of complying with
the securities or blue sky laws of any jurisdictions; provided, however, the
Corporation shall not be liable for (a) any discounts or

                                       4

commissions to any underwriter; (b) any stock transfer taxes incurred with
respect to Option Shares sold in the offering or (c) the fees and expenses of

                                OPTION AGREEMENT

         OPTION AGREEMENT dated as of February 21, 1998, between ACTV, Inc., a
Delaware corporation (the "Corporation") and David Reese (the "Employee").

         The Corporation desires to grant to the Employee the right and option
to purchase up to 1,040,000 shares (the "Option Shares") of Common Stock (the
"Common Stock"), of the Corporation, on the terms and subject to the conditions
hereinafter set forth.

         NOW, THEREFORE, in consideration of the receipt of $1.00 and other good
and valuable consideration, the receipt of which is hereby acknowledged, the
parties hereby agree as follows:

         SECTION 1. OPTION TO PURCHASE COMMON STOCK.

                  a. Subject to Section 5 hereof, the Corporation hereby grants
to the Employee an option (the "Option") to purchase from the Corporation
1,040,000 Option Shares, at a purchase price of $1.60 per Option Share (the
"Option Price"). The Employee's right and option to purchase the Option Shares
shall vest annually commencing January 1, 2000 to and including January 1, 2002,
in three annual installments of 346,667 (on each of January 1, 2000 and January
1, 2001) and 346,666 (on January 1, 2002) Option Shares at the Option Price, so
long as the Employee is employed by the Corporation. Said right shall be
cumulative so that as of January 1, 2002, the Employee shall have the fully
vested right to purchase 1,040,000 Option Shares. In the event that the
Employee's employment with the Corporation terminates prior to any January 1,
the Employee shall not have the right or option to purchase any part of the
respective annual installment of Option Shares that would have otherwise vested
on or after that particular January 1. With respect to the Option, the "Option
Period" shall commence on the date hereof and terminate on December 31, 2006.

                  b. The Option may be exercised by the Employee by delivery to
the Corporation, at any time commencing one year from the date hereof, of a
written notice (the "Option Notice"), which Option Notice shall state the
Employee's intention to exercise the Option, the date on which the Employee
proposes to purchase the Option Shares (the "Closing Date") and the number of
Option Shares to be purchased on the Closing Date, which Closing Date shall be
no later than 30 days nor earlier than 10 days following the date of the Option
Notice. Upon receipt by the Corporation of an Option Notice from the Employee,
the Employee shall be obligated to purchase that number of Option Shares to be
purchased on the Closing Date set forth in the Option

<PAGE>

Notice.

                  c. The purchase and sale of Option Shares acquired pursuant to
the terms of this Option Agreement shall be made on the Closing Date at the
offices of the Corporation. Delivery of the Stock certificate or other
instrument registered in the name of the Employee, evidencing the Option Shares
being purchased on the Closing Date, shall be made by the Corporation to the
holder of this Option on the Closing Date against the delivery to the
Corporation of a check in the full amount of the aggregate purchase price
therefor.

         SECTION 2. REPRESENTATIONS AND WARRANTIES OF THE HOLDER. The Employee
hereby represents and warrants to the Corporation that in the event the Employee
acquires any Option Shares, such Option Shares will be acquired for his own
account, for investment and not with a view to the distribution thereof. The
Employee understands that except as set forth in Section 6 hereof, the Option
Shares will not be registered under the Securities Act of 1933, as amended (the
"Securities Act"), by reason of their issuance in a transaction exempt from the
registration requirements of the Securities Act pursuant to Section 4 (2)
thereof and that they must be held indefinitely unless a subsequent disposition
thereof is registered under the Securities Act or the transaction is except from
registration.

         SECTION 3. REORGANIZATION; MERGERS; SALES; ETC. If, at any time during
the Option Period, there shall be any capital reorganization, reclassification
of Common Stock (other than a change in par value or from par value to nor par
value or from no par value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares), the consolidation or merger of
the Corporation with or into another corporation or of the sale of all or
substantially all the properties and assets of the Corporation as an entirety to
any other corporation or person, the unexercised and fully vested portion of
this Option shall, after such reorganization, reclassification, consolidation,
merger or sale, be exercisable for the kind and number of shares of stock or
other securities or property of the Corporation or of the corporation resulting
from such consolidation or surviving such merger or to which such properties and
assets shall have been sold to which the Employee would have been entitled if
the Employee had held shares of Common Stock issuable upon the exercise hereof
immediately prior to such reorganization, reclassification, consolidation,
merger or sale. The provisions of this Section 3 shall similarly apply to
successive reorganizations, reclassifications, consolidations, mergers and
sales.

         SECTION 4. ADJUSTMENT OF OPTION SHARES AND OPTION PRICE.

                  a. The number of Option Shares subject to this Option during
the Option Period shall be cumulative as to all prior dates of calculation and

of Common Stock.

                  b. If, at any time through December 31, 2001 of the Option
Period, the Corporation issues any previously unissued Common Stock over and
beyond the number shares outstanding February 21, 1998, then the number of
shares subject to the Option shall be adjusted such that the holder thereof
shall have the right to exercise the Option for the same percentage of the
issued and outstanding Common Stock of the Corporation as he held option shares
on February 21, 1998.

                  c. The Option Price shall be subject to adjustment from time
to time as follows:

                           (1) If, at any time during the Option Period, the
number of shares of Common Stock outstanding is increased by a stock dividend
payable in shares of Common Stock or by a subdivision or split-up of shares of
Common Stock, then, immediately following the record date fixed for the
determination of holders of shares of Common Stock entitled to receive such
stock dividend, subdivision or split-up, the Option Price shall be appropriately
decreased so that the number of shares of Common Stock issuable upon the
exercise hereof shall be increased in proportion to such increase in outstanding
shares.

                           (2) If, at any time during the Option Period, the
number of shares of Common Stock outstanding is decreased by a combination of
outstanding shares of Common Stock, then, immediately following the record date
for such combination, the Option Price shall be appropriately increased so that
the number of shares of Common Stock issuable upon the exercise hereof shall be
decreased in proportion to such decrease in outstanding shares.

         SECTION 5. TERMINATION OF THE OPTIONS.

                  a. TERMINATION OF OPTIONS IN GENERAL. Subject to subsections
(b) - (c) of this Section, the Option granted hereby shall terminate and the

                  c. DEATH OF EMPLOYEE. In the event that an Employee shall die
while he is an employee of the Corporation and prior to his complete exercise of
the Option, the Option may be exercised in whole or in part only: (i) by the
Employee's estate or on behalf of such person or persons to whom the Employee's
rights pass under

                                       3

his Will or by the laws of descent and distribution, (ii) to the extent that the
Employee was entitled to exercise the Option at the date of his death, and (iii)
prior to the expiration of the term of the Option.

         SECTION 6. PIGGYBACK REGISTRATION.

                  a. If, at any time commencing January 1, 2000 and expiring

under the Securities Act (other than in connection with a merger or pursuant to
Form S-8 or other comparable Form) it will give written notice by registered

inclusion of any Option Shares shall have been made) to elect not to file any
such proposed registration statement, or to withdraw the same after the filing
