              WARRANT TO PURCHASE 1,250,000 SHARES OF COMMON STOCK

                                  -------------

THIS CERTIFIES THAT, for value received, Adelphia Communications Corporation, a
Delaware corporation whose address is One North Main Street, Coudersport, PA
16915 (the "HOLDER") is entitled to subscribe for and purchase one million two
hundred fifty thousand (1,250,000) (as adjusted pursuant to Section 3 hereof)
shares of fully paid and non-assessable shares of Common Stock (the "SHARES") of
Wink Communications, Inc., a Delaware corporation whose address is 1001 Marina
Village Parkway, Alameda, CA 94501 (the "COMPANY"), at the price of twelve
dollars and twenty one cents ($12.21) per share (the "EXERCISE PRICE") (as
adjusted pursuant to Section 3 hereof), subject to the provisions and upon the
terms and conditions hereinafter set forth.

     1.   Exercise: Payment.


          1.1 Time of Exercise. This Warrant shall become exercisable at any
time after the date of issuance but prior to its expiration pursuant to Section
12 hereof.

          1.2 Method of Exercise.

               (a) Cash Exercise. The purchase rights represented by this
Warrant may be exercised by the Holder, in whole or in part, by the surrender of
this Warrant (with the notice of exercise form attached hereto as Attachment 1
and the investment representation statement attached hereto as Attachment 2,
each duly executed) at the principal office of the Company, and by the



<PAGE>
payment to the Company, by certified, cashier's or other check acceptable to the
Company, of an amount equal to the aggregate Exercise Price of the Shares being
purchased.

               (b) Net Issue Exercise. In lieu of exercising this Warrant for
cash, the Holder may elect to receive Shares equal to the value of this Warrant
(or the portion thereof being canceled) by surrender of this Warrant at the
principal office of the Company together with notice of such election, in which
event the Company shall issue to the Holder a number of shares of the Company's
Common Stock computed using the following formula:

          X = Y (A-B)
              -------
                 A                   Where:

X    =    the number of Shares to be issued to the Holder.

Y    =    the number of Shares purchasable under this Warrant.

A    =    the fair market value of one share of the Company's Common Stock.

B    =    the Exercise Price (as adjusted to the date of such calculation).

               (c) Fair Market Value. For purposes of this Section 2, the fair
market value of the Company's Common Stock shall mean:

                    (i) The closing ask price of the Company's Common Stock
quoted in the NASDAQ Over-the-Counter Market Summary or the closing price quoted
on any exchange on which the Common Stock is listed, whichever is applicable, as
published in the Western Edition of The Wall Street Journal for the ten trading
days prior to the date of determination of fair market value;

                    (ii) If the Company's Common Stock is not traded
Over-the-Counter or on an exchange, the per share fair market value of the
Common Stock shall be the fair market value price per share as determined in
good faith by the Company's Board of Directors.

          1.3 Stock Certificates. Any exercise of this Warrant shall be deemed
to have occurred immediately prior to the close of business on the date of its
surrender for exercise as provided above, and the person entitled to receive the
shares of Common Stock issuable upon such exercise shall be treated for all
purposes as the holder of such shares of record as of the close of business on
such date. In the event of any exercise of the rights represented by this
Warrant, certificates for the shares of Common Stock so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

     2.   Stock Fully Paid; Reservation of Shares. All of the Shares
issuable upon the exercise of the rights represented by this Warrant will, upon
issuance and receipt of the Exercise Price therefor,

                                        -2-

<PAGE>
be fully paid and non-assessable, and free from all taxes, liens and charges
with respect to the issue thereof During the period within which the rights
represented by this Warrant may be exercised, the Company shall at all times
have authorized and reserved for issuance sufficient shares of its Common Stock
to provide for the exercise of the rights represented by this Warrant.

     3.   Adjustment of Exercise Price and Number of Shares. Subject to the
provisions of Section 12 hereof, the number and kind of securities purchasable
upon the exercise of this Warrant and the Exercise Price therefor shall be
subject to adjustment from time to time upon the occurrence of certain events,
as follows:

          3.1 Reclassification. Consolidation or Merger. In case of any
reclassification or change of the Common Stock (other than a change in par
value, or as a result of a subdivision or combination), or in case of any
consolidation or merger of the Company with or into another corporation (other
than a merger with another corporation in which the Company is the surviving
corporation and which does not result in any reclassification or change of
outstanding securities issuable upon exercise of this Warrant), or in case of
any sale of all or substantially all of the assets of the Company, the Company,
or such successor or purchasing corporation as the case may be, shall in
connection with such transaction execute a new Warrant, providing that the
holder of this Warrant shall have the right to exercise such new Warrant, and
procure upon such exercise and payment of the same aggregate Exercise Price, in
lieu of the shares of Common Stock theretofore issuable upon exercise of this
Warrant, the kind and amount of shares of stock, other securities, money and
property receivable upon such reclassification, change, consolidation, sale of
all or substantially all of the Company's assets or merger by a holder of an
equivalent number of shares of Common Stock. Such new Warrant shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 3. The provisions of this subsection
(a), subject to Section 12 hereof, shall similarly apply to successive
reclassifications, changes, consolidations, mergers, transfers and the sale of
all or substantially all of the Company's assets.

          3.2 Stock Splits, Dividends and Combinations. In the event that the
Company shall at any time subdivide the outstanding shares of Common Stock or
shall issue a stock dividend on its outstanding shares of Common Stock the
number of Shares issuable upon exercise of this Warrant immediately prior to
such subdivision or to the issuance of such stock dividend shall be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine the
outstanding shares of Common Stock the number of Shares issuable upon exercise
of this Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

     4.   Notice of Adjustments. Whenever the number of Shares purchasable
hereunder or the Exercise Price thereof shall be adjusted pursuant to Section 3
hereof, the Company shall provide written notice to the holder of this Warrant
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated,
and the number of Shares which may be purchased and the Exercise Price therefor
after giving effect to such adjustment.



                                      -3-
<PAGE>

     5.   Fractional Shares. No fractional shares of Common Stock will be issued
in connection with any exercise hereunder. In lieu of such fractional shares,
the Company shall make a cash payment therefor based upon the Exercise Price
then in effect.

     6.   Representations of the Company. The Company represents that, except as
contemplated by Section 10 hereof, all corporate actions on the part of the
Company, its officers, directors and stockholders necessary for the sale and
issuance of the Shares pursuant hereto and the performance of the Company's
obligations hereunder were taken prior to and are effective as of the effective
date of this Warrant.

     7.   Representations and Warranties by the Holder.  The Holder represents
and warrants to the Company as follows:

          7.1 This Warrant and the Shares issuable upon exercise thereof are
being acquired for its own account, for investment and not with a view to, or
for resale in connection with, any distribution or public offering thereof
within the meaning of the Securities Act of 1933, as amended (the "SECURITIES
ACT"). Upon exercise of this Warrant, the Holder shall, if so requested by the
Company, confirm in writing, in a form satisfactory to the Company, that the
securities issuable upon exercise of this Warrant are being acquired for
investment and not with a view toward distribution or resale.

          7.2 The Holder understands that the Warrant and the Shares have not
been registered under the Securities Act by reason of their issuance in a
transaction exempt from the registration and prospectus delivery requirements of
the Securities Act pursuant to Section 4(2) thereof, that they must be held by
the Holder indefinitely, and that the Holder must therefore bear the economic
risk of such investment indefinitely, unless a subsequent disposition thereof is
registered under the Securities Act or is exempted from such registration.

          7.3 The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

          7.4 The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     8.   Restrictive Legend.  The Shares issuable upon exercise of this Warrant
(unless registered under the Securities Act) shall be stamped or imprinted with
a legend in substantially the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
          SOLELY FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE
          SECURITIES LAWS. SUCH SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE,
          PLEDGED OR



                                      -4-
<PAGE>

          HYPOTHECATED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF
          COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH SALE,
          OFFER OR PLEDGE IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
          DELIVERY REQUIREMENTS OF THE ACT AND OF ANY APPLICABLE STATE
          SECURITIES LAWS.

     9.   Restrictions Upon Transfer and Removal of Legend. Subject to the
provisions of the Rights Agreement referenced in Section 10, below:

          9.1 The Company need not register a transfer of Shares bearing the
restrictive legend set forth in Section 8 hereof, unless the conditions
specified in such legend are satisfied. The Company may also instruct its
transfer agent not to register the transfer of the Shares, unless one of the
conditions specified in the legend referred to in Section 8 hereof is satisfied.

          9.2 In order to effect any transfer of all or a portion of this
Warrant or the Shares, the transferor shall deliver a completed and duly
executed Notice of Transfer (attached hereto as Attachment 3).

     10.  Associated Rights. The Company agrees to use commercially reasonable
efforts to ensure that the Holder shall be entitled to such registration rights
as the Company has granted to investors in the Company generally, as are set
forth in the Fourth Amended and Restated Investors Rights Agreement dated as of
June 30, 1999, as amended to date and as further modified by the Consent and
Amendment of Investor Rights dated on or about the date hereof (collectively,
the "Rights Agreement"). The Company agrees to use commercially reasonable steps
to obtain all necessary waivers and consents from existing investors under such
Rights Agreement to amend such agreements to provide the Holder with such rights

     11. Rights of Stockholders. No holder of this Warrant shall be entitled, as
a Warrant holder, to vote or receive dividends or be deemed the holder of Common
Stock or any other securities of the Company which may at any time be issuable
on the exercise hereof for any purpose, nor shall anything contained herein be
construed to confer upon the holder of this Warrant, as such, any of the rights
of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to stockholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, consolidation, merger, conveyance, or otherwise) or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until the
Warrant shall have been exercised and the Shares purchasable upon the exercise
hereof shall have become deliverable, as provided herein.

     12.  Expiration of Warrant. This Warrant shall expire and shall no longer
be exercisable (to the extent, if at all, it has been come exercisable prior to
such expiration) upon the earlier to occur of:

                      INVESTMENT REPRESENTATION STATEMENT

PURCHASER  :   ADELPHIA COMMUNICATIONS CORPORATION

SELLER     :   WINK COMMUNICATIONS, INC.

ISSUER     :   WINK COMMUNICATIONS, INC.

SECURITY   :   COMMON STOCK ISSUED UPON EXERCISE OF THE STOCK PURCHASE WARRANT
               ISSUED ON OCTOBER 20,2000

AMOUNT     :   ___________ SHARES

DATE       :   _______________

In connection with the purchase of the above-listed Securities, the Purchaser
represents to the Seller and to the Company the following:

(a)  Purchaser is aware of the Company's business affairs and financial
condition, and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Purchaser is
purchasing these Securities for its own account for investment purposes only and
not with a view to, or for the resale in connection with, any "distribution"
thereof for purposes of the Securities Act of 1933, as amended (the "Securities
Act").

(b)  Purchaser understands that the Securities have not been registered under
the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of its
investment intent as expressed herein. In this connection, Purchaser understands
that, in the view of the Securities and Exchange Commission (the "SEC"), the
statutory basis for such exemption may be unavailable if its representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one year or any other fixed period in the future.

(c) Purchaser further understands that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. Moreover, Purchaser understands that
the Company is under no obligation to register the Securities, other than as
granted to investors in the Company generally as set forth in this Warrant and
the Fourth Amended and Restated Investor Rights Agreement dated as of June 30,
1999, as amended to date and as further modified by the Consent and Amendment of
Investors Rights Agreement dated on or about the date of this Warrant and as may
be subsequently amended. In addition, Purchaser understands that, unless the
Securities have been registered under the Securities Act, the certificate
evidencing the Securities will be imprinted with a legend which



                                      -2-
<PAGE>

prohibits the transfer of the Securities unless the Company receives an opinion
of counsel reasonably acceptable to it stating that such sale or transfer is
exempt from registration and prospectus delivery requirements of the Securities
Act.

(d)  Purchaser is familiar with the provisions of Rule 144, promulgated under
the Securities Act, which, in substance, permit limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof, in a non-public offering subject to the satisfaction of certain
conditions. In particular, the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires among other
things: (1) the availability of certain public information about the Company,
(2) the resale occurring not less than one year after the party has purchased,
and made full payment for, within the meaning of Rule 144, the securities to be
sold; and, in the case of an affiliate, or of a non-affiliate who has held the
securities not less than two years, (3) the sale being made through a broker in
an unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934) and
the amount of securities being sold during any three month period not exceeding
the specified limitations stated therein, if applicable.

(e)  Purchaser further understands that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 are not exclusive,
the Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.
