NEITHER THE EXCHANGE RIGHT GRANTED HEREIN NOR ANY OF THE SECURITIES ISSUABLE
UPON EXERCISE OF SUCH EXCHANGE RIGHT HAVE BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS. NO
TRANSFER OF SUCH EXCHANGE RIGHT OR OF THE SECURITIES ISSUABLE UPON EXERCISE OF
SUCH EXCHANGE RIGHT SHALL BE VALID OR EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE
PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN
COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS OR (B) THE HOLDER HEREOF
SHALL DELIVER TO THE COMPANY AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS EXEMPT FROM THE
REGISTRATION OR QUALIFICATION REQUIREMENTS OF THE SECURITIES ACT AND ANY
APPLICABLE STATE SECURITIES LAWS.

                               EXCHANGE AGREEMENT

         This Exchange Agreement (this "Exchange Agreement") is entered into on
this 12th day of September, 2000, by and between USDATA Corporation, a Delaware
corporation (the "Company"), and SCP Private Equity Partners II, L.P. ("SCP,"
and together with each of its assignees and transferees, individually, a
"Holder" and, collectively, the "Holders"). Subject to the terms and conditions
set forth herein, including, without limitation, Section 3 hereof, the Company
hereby grants to the Holder the right to exchange (the "Exchange Right") shares
of the Series A-1 Convertible Preferred Stock, par value $0.01 per share (the
"eMake Preferred Stock"), of eMake Corporation, a Delaware corporation
("eMake"), owned by the Holder for fully paid and non-assessable shares of the
Company's Series B Convertible Preferred Stock, par value $0.01 per share (the
"Company Preferred Stock").

         1. Exercise of Exchange Right.

                  1.1 Exchange Rate. Subject to adjustment as provided in
Section 3 hereof, 0.025 of a share of Company Preferred Stock (the "Exchange
Rate") shall be issuable hereunder (the "Exchange Shares") for each share of
eMake Preferred Stock owned by the Holder tendered for exchange pursuant to the
Exchange Right.

                  1.2 Exerciseability. The Exchange Right shall be exercisable,
in whole or in part, from time to time and at any time on and after the date
hereof until 5:00 p.m., eastern time, on the Expiration Date (as hereinafter
defined), in accordance with Section 1.3 hereof. As used herein, the term
"Expiration Date" means the earlier of (i) June 30, 2006, or (ii) the date on
which the Holder no longer owns any shares of eMake Preferred Stock (or other
securities obtained as a result of changes or reclassifications of eMake
Preferred Stock pursuant to Section 3.1.5 hereof).

<PAGE>   2

                  1.3 Exercise. Upon tender of a duly executed Notice of
Exercise in the form of Annex A attached hereto, together with the original
certificate(s) representing the shares of eMake Preferred Stock being exchanged
for the Exchange Shares to be acquired, at the Company's principal executive
offices presently located at 2345 North Central Expressway, Richardson, Texas,
75080, Attention: President, or at such other address as the Company shall have
advised the Holder in writing (the "Designated Office"), the Holder shall be
entitled to receive a certificate or certificates for the Exchange Shares so
acquired. The Company agrees that the Exchange Shares shall be deemed to have
been issued to the Holder as of the close of business on the date on which the
Company receives a duly executed Notice of Exercise covering such Exchange
Shares and the related certificates representing the shares of eMake Preferred
Stock being exchanged therefor as described above.

         2. Transfer; Issuance of Stock Certificates; Restrictive Legends.

                  2.1 Transfer. Subject to compliance with the restrictions on
transfer set forth in this Section 2, the Exchange Right granted hereunder with
respect to any shares of eMake Preferred Stock may be transferred or assigned to
any transferee or assignee of such shares of eMake Preferred Stock, upon
delivery to the Company of a written assignment with respect thereto in the form
of Annex B attached hereto duly executed by the Holder or its agent or attorney.
Upon such delivery, the Company shall execute and deliver a new Exchange
Agreement or Exchange Agreements in the name of the assignee or assignees. An
Exchange Right, if properly assigned in compliance with the provisions hereof,
may be exercised by the new Holder for the acquisition of Exchange Shares
without having a new Exchange Agreement issued. Prior to due presentment for
registration of transfer thereof, the Company may deem and treat the registered
Holder of the Exchange Right as the absolute owner hereof (notwithstanding any
notations of ownership or writing thereon made by anyone other than a duly
authorized officer of the Company) for all purposes and shall not be affected by
any notice to the contrary. All Exchange Agreements issued upon any assignment
of the Exchange Right shall be the valid obligations of the Company, evidencing
the same rights, and entitled to the same benefits as this Exchange Agreement
with respect to the portion of the Exchange Right transferred or assigned, upon
registration of transfer or exchange.

                  2.2 Stock Certificates. Certificates for the Exchange Shares
shall be delivered to the Holder within a reasonable time after the Exchange
Right shall have been exercised pursuant to Section 1. The issuance of
certificates for Exchange Shares upon the exercise of the Exchange Right shall
be made without charge to the Holder hereof including, without limitation, any
documentary, stamp or similar tax that may be payable in respect thereof;
provided, however, that the Company shall not be required to pay any income tax
to which the Holder hereof may be subject in connection with the issuance of
this Exchange Agreement or the Exchange Shares; and provided further, that if
Exchange Shares are to be delivered in a name other than the name of the Holder
hereof representing any Exchange Right being exercised, then no such delivery
shall be made unless the person requiring the same has paid to the Company the
amount of transfer taxes or charges incident thereto, if any.

         2.3 Restrictive Legends.

                  (a) Except as otherwise provided in this Section 2, each
certificate for Exchange Shares initially issued upon the exercise of the
Exchange Right, and each certificate for Exchange Shares issued to any
subsequent transferee of any such certificate, shall be stamped or otherwise
imprinted with a legend in substantially the following form:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
         ANY STATE SECURITIES LAW. NO TRANSFER OF THE SHARES REPRESENTED BY THIS
         CERTIFICATE OR ISSUED UPON CONVERSION OF SUCH SHARES SHALL BE VALID OR
         EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH
         ANY APPLICABLE STATE SECURITIES LAWS, OR (B) THE HOLDER SHALL DELIVER
         TO THE COMPANY AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY
         ACCEPTABLE TO THE COMPANY THAT SUCH PROPOSED TRANSFER IS EXEMPT FROM
         THE REGISTRATION OR QUALIFICATION REQUIREMENTS OF THE SECURITIES ACT
         AND ANY APPLICABLE STATE SECURITIES LAWS."

                  (b) Except as otherwise provided in this Section 2, each
Exchange Agreement shall be stamped or otherwise imprinted with a legend in
substantially the following form:

         "NEITHER THE EXCHANGE RIGHT GRANTED HEREIN NOR ANY OF THE SECURITIES
         ISSUABLE UPON EXERCISE OF SUCH EXCHANGE RIGHT HAVE BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
         ANY STATE SECURITIES LAWS. NO TRANSFER OF SUCH EXCHANGE RIGHT OR OF THE
         SECURITIES ISSUABLE UPON EXERCISE OF SUCH EXCHANGE RIGHT SHALL BE VALID
         OR EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH
         ANY APPLICABLE STATE SECURITIES LAWS OR (B) THE HOLDER HEREOF SHALL
         DELIVER TO THE COMPANY AN OPINION OF COUNSEL IN FORM AND SUBSTANCE
         REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS EXEMPT FROM
         THE REGISTRATION OR QUALIFICATION REQUIREMENTS OF THE SECURITIES ACT
         AND ANY APPLICABLE STATE SECURITIES LAWS."

Notwithstanding the foregoing, the legend requirements of this Section 2.3 shall
terminate as to any particular Exchange Agreement or Exchange Share when the
Company shall have received from the Holder thereof an opinion of counsel in
form and substance reasonably acceptable to the Company that such legend is not
required in order to ensure compliance with the Securities Act and applicable
state securities laws. Whenever the restrictions imposed by this Section 2.3
shall terminate, the holder hereof or of Exchange Shares, as the case may be,
shall be entitled to receive from the Company without cost to such holder a new
Exchange Agreement or certificate for Exchange Shares of like tenor, as the case
may be, without such restrictive legend.

         3. Adjustment of Exchange Rate; Nature of Securities Issuable Upon
Exercise of Exchange Right.

                  3.1 Exchange Rate; Adjustment of Number of Shares. The
Exchange Rate set forth in Section 1 hereof shall be subject to adjustment from
time to time as hereinafter provided.

                           3.1.1 Merger, Sale of Assets, etc. If at any time
while the Exchange Right, or any portion thereof, is outstanding and unexpired
there shall be a reorganization (other than a combination, reclassification,
exchange, or subdivision of shares as provided in Sections 3.1.2 and 3.1.3),
merger or consolidation of the Company with or into another corporation in which
the Company is not the surviving entity, or a merger in which the Company is the
surviving entity but the shares of the Company's capital stock outstanding
immediately prior to the merger are converted by virtue of the merger into other
property, whether in the form of securities, cash, or otherwise, or a sale or
transfer of the Company's properties and assets as, or substantially as, an
entirety to any other person, then, as a part of such reorganization, merger,
consolidation, sale or transfer, lawful provision shall be made so that the
holder of this Exchange Agreement shall thereafter be entitled to receive upon
exercise of the Exchange Right, during the period specified herein and upon
delivery of the shares of eMake Preferred Stock being exchanged pursuant hereto,
the number of shares of stock or other securities or cash or property of the
successor corporation resulting from such reorganization, merger, consolidation,
sale or transfer that a holder of the shares deliverable upon exercise of the
Exchange Right would have been entitled to receive in such reorganization,
consolidation, merger, sale or transfer if the Exchange Right had been exercised
immediately before such reorganization, consolidation, merger, sale or transfer,
all subject to further adjustment as provided in this Section 3. The foregoing
provisions of this Section 3.1.1 shall similarly apply to successive
reorganizations, consolidations, mergers, sales and transfers and to the stock
and securities of any other corporation that are at the time receivable upon the
exercise of the Exchange Right. If the per share consideration payable to the
Holder hereof for shares in connection with any such transaction is in a form
other than cash or securities, then the value of such consideration shall be
determined in good faith by the Company's Board of Directors. In all events,
appropriate adjustment shall be made in the application of the provisions of
this Exchange Agreement with respect to the rights and interests of the Holder
hereof after the transaction, to the end that the provisions of this Exchange
Agreement shall be applicable after that event, as near as reasonably may be, in
relation to any shares or other property deliverable after that event upon
exercise of the Exchange Right.

                           3.1.2 Reclassification, etc. If the Company, at any
time while the Exchange Right, or any portion thereof, remains outstanding and
unexpired, shall, by the

                                       4
<PAGE>   5

reclassification or exchange of securities or otherwise, change any of the
securities issuable upon exercise of the Exchange Right into the same or a
different number of securities of any other class or classes, this Exchange
Agreement shall thereafter represent the right to acquire such number and kind
of securities as would have been issuable as the result of such change with
respect to the securities issuable upon exercise of the Exchange Right
immediately prior to such reclassification, exchange, or other change and the
Exchange Rate therefor shall be appropriately adjusted, all subject to further
adjustment as provided in this Section 3.

                           3.1.3 Stock Splits, Stock Dividends and Reverse Stock
Splits. In case at any time the Company shall split or subdivide the outstanding
shares of Company Preferred Stock into a greater number of shares, or shall
declare and pay any stock dividend with respect to its outstanding stock that
has the effect of increasing the number of outstanding shares of Company
Preferred Stock, the Exchange Rate in effect immediately prior to such
subdivision or stock dividend shall be proportionately increased, and
conversely, in case at any time the Company shall combine its outstanding shares
of Company Preferred Stock into a smaller number of shares, the Exchange Rate in
effect immediately prior to such combination shall be proportionately reduced.

                           3.1.4 Adjustments for Dividends in Stock or Other
Securities of Property. If while the Exchange Right, or any portion hereof,
remains outstanding and unexpired the holders of Company Preferred Stock shall
have received, or, on or after the record date fixed for the determination of
eligible stockholders, shall have become entitled to receive, without payment
therefor, other or additional stock or other securities or property (other than
cash) of the Company by way of dividend, then and in each case, this Exchange
Agreement shall represent the right to acquire, in addition to the number of
shares of the security receivable upon exercise of the Exchange Right, and
without payment of any additional consideration therefor, the amount of such
other or additional stock or other securities or property of the Company that
such holder would hold on the date of such exercise had it been the holder of
record of the security receivable upon exercise of the Exchange Right on the
date hereof and had thereafter, during the period from the date hereof to and
including the date of such exercise, retained such shares and/or all other
additional stock available by it as aforesaid during such period, giving effect
to all adjustments called for during such period by the provisions of this
Section 3.

                           3.1.5 eMake Reclassification, etc. If eMake, at any
time while the Exchange Right, or any portion thereof, remains outstanding and
unexpired, shall, by the reclassification or exchange of securities or
otherwise, change the eMake Preferred Stock into the same or a different number
of securities of any other class or classes, this Exchange Agreement shall
thereafter represent the right to exchange the securities into or for which the
eMake Preferred Stock is reclassified, exchanged or changed and the Exchange
Rate therefor shall be appropriately adjusted, all subject to further adjustment
as provided in this Section 3.

                           3.1.6 eMake Stock Splits, Stock Dividends and Reverse
Stock Splits. In case at any time eMake shall split or subdivide the outstanding
shares of eMake Preferred Stock into a greater number of shares, or shall
declare and pay any stock dividend with respect to its outstanding stock that
has the effect of increasing the number of outstanding shares of eMake Preferred
Stock, the Exchange Rate in effect immediately prior to such subdivision or
stock dividend shall be proportionately reduced, and conversely, in case at any
time eMake shall

                                       5
<PAGE>   6

combine its outstanding shares of eMake Preferred Stock into a smaller number of
shares, the Exchange Rate in effect immediately prior to such combination shall
be proportionately increased.

                           3.1.7 Adjustments for Dividends in eMake Stock or
Other Securities of Property. If while the Exchange Right, or any portion
hereof, remains outstanding and unexpired, the holders of eMake Preferred Stock
shall have received, or, on or after the record date fixed for the determination
of eligible stockholders, shall have become entitled to receive, without payment
therefor, other or additional stock or other securities or property (other than
cash) of eMake by way of dividend, then and in each case, upon exercise of the
Exchange Right, in addition to the number of shares of eMake Preferred Stock
deliverable hereunder, the Holder shall also deliver to the Company such other
or additional stock or other securities or property of eMake that such Holder
received with respect to the eMake Preferred Stock being exchanged during such
period, giving effect to all adjustments called for during such period by the
provisions of this Section 3.

                  3.2 Timing of Exchange Rate Adjustment. No adjustment of the
Exchange Rate shall be made unless such adjustment would require an increase or
decrease of at least 0.0001 in such rate; provided, however, that any
adjustments which by reason of this Section 3.2 are not required to be made
shall be carried forward and shall be made at the time of and together with the
next subsequent adjustment which, together with any adjustments so carried
forward, shall require an increase or decrease of at least 0.0001 in the
Exchange Rate then in effect hereunder.

                  3.3 Adjustment Certificate. In each case of an adjustment in
the Exchange Rate, the Company shall compute and prepare a certificate setting
forth such adjustment and showing in detail the facts upon which such adjustment
is based, including a statement of (i) the number of Company Preferred Stock
outstanding or deemed to be outstanding, (ii) the adjusted Exchange Rate and
(iii) the number of Exchange Shares issuable upon exercise of this Exchange
Right. The Company will forthwith mail a copy of each such certificate to the
holder hereof.

         4. Registration; Exchange and Replacement of Exchange Agreement;
Reservation of Shares. The Company shall keep at the Designated Office a
register in which the Company shall provide for the registration, transfer and
exchange of the Exchange Right. The Company shall not at any time, except upon
the dissolution, liquidation or winding-up of the Company, close such register
so as to result in preventing or delaying the exercise or transfer of the
Exchange Right.

         The Company may deem and treat the person in whose name the Exchange
Right is registered as the holder and owner hereof for all purposes and shall
not be affected by any notice to the contrary, until registration of any
transfer as provided in this Section 4.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Exchange Agreement and (in
case of loss, theft or destruction) of indemnity satisfactory to it, and (in the
case of mutilation) upon surrender and cancellation of this Exchange Agreement,
the Company will (in the absence of notice to the Company that the Exchange
Agreement has been acquired by a bona fide purchaser) make and deliver a new

                                       6
<PAGE>   7

Exchange Agreement of like tenor, in lieu of this Exchange Agreement without
requiring the posting of any bond or the giving of any security.

         The Company shall at all times reserve and keep available out of its
authorized shares of Company Preferred Stock, solely for the purpose of issuance
upon the exercise of the Exchange Right, such number of shares of Company
Preferred Stock as shall be issuable upon the exercise hereof. The Company
covenants and agrees that, upon exercise of the Exchange Right and receipt of
the shares of eMake Preferred Stock therefor, all Exchange Shares issuable upon
such exercise shall be duly and validly issued, fully paid and non-assessable.

         5. Fractional Shares. The Company shall not be required to issue
fractions of shares, upon exercise of the Exchange Right or otherwise, or to
distribute certificates that evidence fractional shares. With respect to any
fraction of a share called for upon any exercise hereof, the Company shall pay
to the Holder an amount in cash equal to such fraction multiplied by the current
market value of such fractional share as may be prescribed by the Board of
Directors of the Company.

         6. Holders Not Deemed Stockholders. No holder of the Exchange Right
shall, as such, be entitled to vote or to receive dividends or be deemed the
holder of Exchange Shares that may at any time be issuable upon exercise of the
Exchange Right for any purpose whatsoever, nor shall anything contained herein
be construed to confer upon any Holder of the Exchange Right, 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 shareholders at any meeting
thereof, or 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, issue or reclassification
of stock, change of par value or change of stock to no par value, consolidation,
merger or conveyance or otherwise), or to receive notice of meetings, or to
receive dividends or subscription rights, until such holder shall have exercised
the Exchange Right and been issued Exchange Shares in accordance with the
provisions hereof.

         7. Notices. All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made when
delivered personally, or mailed by registered or certified mail, return receipt
requested, or telecopied or telexed and confirmed in writing and delivered
personally or mailed by registered or certified mail, return receipt requested
(a) if to the holder of the Exchange Right, to the address of such Holder as
shown on the books of the Company, or (b) if to the Company, to the address set
forth in Section 1.3 of this Exchange Agreement; or at such other address as the
Holder or the Company may hereafter have advised the other.

         8. Successors. All the covenants, agreements, representations and
warranties contained in this Exchange Agreement shall bind the parties hereto
and their respective heirs, executors, administrators, distributees, successors,
assigns and transferees.

         9. Law Governing. This Exchange Agreement shall be construed and
enforced in accordance with, and governed by, the laws of the State of Delaware
(not including the choice of law rules thereof) regardless of the jurisdiction
of creation or domicile of the Company or its successors or of the holder at any
time hereof.

                                       7

         10. Entire Agreement; Amendments and Waivers. This Exchange Agreement
sets forth the entire understanding of the parties with respect to the
transactions contemplated hereby. The failure of any party to seek redress for
the violation or to insist upon the strict performance of any term of this
Exchange Agreement shall not constitute a waiver of such term and such party
shall be entitled to enforce such term without regard to such forbearance. This
Exchange Agreement may be amended, and any breach of or compliance with any
covenant, agreement, warranty or representation may be waived, only if the
Company has obtained the written consent or written waiver of the Holder, and
then such consent or waiver shall be effective only in the specific instance and
for the specific purpose for which given.

         11. Severability; Headings. If any term of this Exchange Agreement as
applied to any person or to any circumstance is prohibited, void, invalid or
unenforceable in any jurisdiction, such term shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or invalidity without in any way
affecting any other term of this Exchange Agreement or affecting the validity or
enforceability of this Exchange Agreement or of such provision in any other
jurisdiction. The Section headings in this Exchange Agreement have been inserted
for purposes of convenience only and shall have no substantive effect.

Exchange Agreement to be duly executed as of the date first written above.

WE-019                                                            12,500 Shares

                             NTN COMMUNICATIONS INC.

             (Incorporated under the laws of the State of Delaware)

        WARRANT CERTIFICATE FOR THE PURCHASE OF SHARES OF THE $.005 PAR VALUE
   COMMON STOCK OF NTN COMMUNICATIONS INC.

   EXERCISABLE AFTER AUGUST 1, 2000 AND ON OR BEFORE JUNE 13, 2005

Warrant Price: $3.00 (Three Dollars) per share.

         1. THIS IS TO CERTIFY that, for value received, Gray & Yorg, LLC (the
"Holder"), is entitled to purchase, subject to the terms and conditions
hereinafter set forth, at any time from and after August 1, 2000, and on or
before June 13, 2005, up to 12,500 shares of the $.005 par value common stock
("Common Stock") of NTN Communications Inc. (the "Company"), and to receive
certificate(s) for the Common Stock so purchased. This Warrant may be exercised
in whole or in part. Such exercise shall be accomplished by tender to the
Company of the purchase price set forth above as the warrant price (the "Warrant
Price"), either in cash or by certified check or bank cashier's check, payable
to the order of the Company, together with presentation and surrender to the
Company of this Warrant with an executed subscription in substantially the form
attached hereto as Exhibit A. Fractional shares of the Company's Common Stock
will not be issued upon the exercise of this Warrant.

         2. The Company agrees at all times to reserve and hold available out of
the aggregate of its authorized but unissued Common Stock the number of shares
of its Common Stock issuable upon the exercise of this and all other Warrants of
like tenor then outstanding. The Company further covenants and agrees that all
shares of Common Stock that may be delivered upon the exercise of this Warrant
will, upon delivery, be fully paid and nonassessable and free from all taxes,
liens and charges with respect to the purchase thereof hereunder.

         This Warrant and the Common Stock issuable upon the exercise hereof may
not be sold, transferred, pledged or hypothecated unless the Company shall have
been supplied with evidence reasonably satisfactory to it that such transfer is
not in violation of the

<PAGE>   2

Securities Act of 1933, as amended (the "Act") or any applicable state laws.
Subject to the satisfaction of the aforesaid condition, this Warrant shall be
transferable by the Holder.

         If this Warrant is transferred, in whole or in part, upon surrender of
this Warrant to the Company, the Company shall deliver to each transferee a
Warrant evidencing the rights of such transferee to purchase the number of
shares of Common Stock that such transferee is entitled to purchase pursuant to
such transfer.

         The Company may place a legend on this Warrant or any replacement
Warrant and on each certificate representing shares issuable upon exercise of
this Warrant as to which the Company has not been supplied evidence that the
transfer of such security would not be in violation of the Act and any
applicable state laws.

         3. This Warrant does not entitle the Holder to any voting rights or
other rights as a stockholder of the Company, nor to any other rights whatsoever
except the rights herein set forth, and no dividend shall be payable or accrue
by reason of this Warrant or the interest represented hereby, or the shares
purchasable hereunder, until or unless, and except to the extent that, this
Warrant is exercised.

         This Warrant is exchangeable upon its surrender by the Holder to the
Company for new Warrants of like tenor and date representing in the aggregate
the right to purchase the number of shares purchasable hereunder, each of such
new Warrants to represent the right to purchase such number of shares as may be
designated by the Holder at the time of such surrender.

         The Company shall comply with the reporting requirements of Sections 13
and 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act") for so
long as and to the extent that such requirements apply to the Company.

         4. The Warrant Price and the number of shares purchasable upon the
exercise of this Warrant are subject to adjustment from time to time upon the
occurrence of any of the events specified in this Section 4.

<PAGE>   3

                  (a) In case the Company shall (i) pay a dividend in shares of
Common Stock or make a distribution in shares of Common Stock, (ii) subdivide
its outstanding shares of Common Stock, (iii) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock, or (iv) issue by
reclassification of its shares of Common Stock other securities of the Company,
the number of shares of Common Stock purchasable upon exercise of this Warrant
immediately prior thereto shall be adjusted so that the Holder of this Warrant
shall be entitled to receive the kind and number of shares of Common Stock or
other securities of the Company that he would have owned or have been entitled
to receive after the happening of any of the events described above, had such
Warrant been exercised immediately prior to the happening of such event or any
record date with respect thereto. An adjustment made pursuant to this paragraph
(a) shall become effective immediately after the effective date of such event
retroactive to the record date, if any, for such event.

                  (b) Whenever the number of shares of Common Stock purchasable
upon the exercise of this Warrant is adjusted, as herein provided, the Warrant
Price shall be adjusted by multiplying such Warrant Price immediately prior to
such adjustment by a fraction, of which the numerator shall be the number of
shares of Common Stock purchasable upon the exercise of this Warrant immediately
prior to such adjustment, and of which the denominator shall be the number of
shares of Common Stock so purchasable immediately thereafter.

                  (c) For the purpose of this Section 4, the term shares of
Common Stock shall mean (i) the class of stock designated as the Common Stock of
the Company at the date of this Warrant, or (ii) any other class of stock
resulting from successive changes or reclassifications of such shares consisting
solely of change in par value, or from par value to no par value, or from no par
value to par value.

                  (d) If during the Warrant Period the Company consolidates with
or merges into another corporation or transfers all or substantially all of its
assets, the Holder shall thereafter be entitled upon exercise hereof to
purchase, with respect to each share of Common Stock purchasable hereunder
immediately prior to the date upon which such consolidation or merger becomes
effective, the securities or property to which a holder of shares of Common
Stock is entitled upon such consolidation or merger, without any change in, or
payment in addition to the Warrant Price in effect immediately prior to such
merger or consolidation, and the Company shall take such steps in connection
with such consolidation or merger as may be necessary to ensure that all of the
provisions of this Warrant shall thereafter be applicable, as nearly as
reasonably may be, in relation to any securities or property thereafter
deliverable upon the exercise of this Warrant. The Company shall not effect any
such consolidation, merger or asset transfer unless prior to the consummation
thereof the successor corporation resulting therefrom shall assume by written
agreement executed and mailed to the registered Holder at his address shown on
the books and records of the Company, the obligation to deliver to such Holder
any such securities or property as in accordance with the foregoing provisions
such Holder shall be entitled to purchase.

<PAGE>   4

                  (e) Upon the happening of any event requiring an adjustment of
the Warrant Price, the Company shall forthwith give written notice thereof to
the registered Holder of this Warrant, stating the adjusted Warrant Price and
the adjusted number of shares of Common Stock or other securities or property
purchasable upon the exercise hereof resulting from such event and setting forth
in reasonable detail the method of calculation and the facts upon which such
calculation is based. The Board of Directors of the Company shall determine the
adjusted Warrant Price and the securities or property purchasable upon exercise.
If any voluntary or involuntary dissolution, liquidation, or winding up of the
Company is proposed, the Company shall give at least 20 days prior written
notice of such proposal to the registered Holder hereof stating the date on
which such event is to take place and the date (which shall be at least 20 days
after giving of such notice) as of which the holders of shares of Common Stock
of record shall be entitled to exchange their Common Stock for securities or
other property deliverable upon such dissolution, liquidation or winding up.
This Warrant and all rights hereunder shall terminate as of the date on which
such dissolution, liquidation, or winding up takes place. The notices pursuant
to this paragraph shall be given by first class mail, postage prepaid, addressed
to the registered Holder of this Warrant at his address appearing in the records
of the Company.

                  (f) Irrespective of any adjustments pursuant to this Section 4
to the Warrant Price or to the number of shares or other securities or other
property obtainable upon exercise of this Warrant, this Warrant may continue to
state the Warrant Price and the number of shares obtainable upon exercise, as
the same price and number of shares stated herein.

         5. Notwithstanding anything to the contrary herein the Exercise Dates
shall automatically be accelerated immediately upon a Change in Control Event. A
"Change in Control Event" shall mean:

         (1) The acquisition by any individual entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act (a "Person")) of
beneficial ownership of 50% or more of the then outstanding voting securities of
the Corporation entitled to vote generally in the election of directors (the
"Outstanding Voting Securities"); provided, however, that the following
acquisitions shall not constitute a Change in Control Event: (A) any acquisition
by the Corporation or (B) any acquisition by any employee benefit plan (or
related trust) sponsored or maintained by the Corporation or any corporation
controlled by the Corporation; or

         (2) Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual who becomes a director subsequent
to the date hereof whose election, or nomination for election by the
Corporation's shareholders, was approved by a vote of at least a majority of the
directors then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board; but excluding, for this
purpose, any such individual whose initial assumption of office occurs

<PAGE>   5

as a result of either an actual or threatened election contest (as such terms
are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) or
other actual or threatened solicitation of proxies or consents by or on behalf
of a Person other than the Board; or

         (3) Approval by the shareholders of the Corporation of a
reorganization, merger or consolidation (a "transaction"), unless, following
such transaction in each case, more than 50% of, respectively, the then
outstanding shares of common stock of the corporation resulting from such
transaction and the combined voting power of the then outstanding voting
securities of such corporation entitled to vote generally in the election of
directors is then beneficially owned, directly or indirectly, by all or
substantially all of the individuals and entities who were beneficial owners,
respectively, of the outstanding Common Stock and outstanding voting securities
of the Corporation immediately prior to such transaction; or

         (4) Approval by the shareholders of the Corporation of (A) a complete
liquidation or dissolution of the Corporation or (B) the sale or other
disposition of all or substantially all of the assets of the Corporation, unless
such assets are sold to a corporation and following such sale or other
disposition, the condition described in paragraph (3) above is satisfied.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
its duly authorized officers, and the corporate seal hereunto affixed.

                                SUBSCRIPTION FORM

     (To be executed by the Registered Holder to exercise the rights to purchase
     Common Stock evidenced by the within Warrant)

         The undersigned hereby irrevocably subscribes for ______ shares (the
     "Stock") of the Common Stock of NTN Communications, Inc. (the "Company")
     pursuant to and in accordance with the terms and conditions of the attached
     Warrant and hereby makes payment of $_________ therefore, and requests that
     a certificate for such shares be issued in the name of the undersigned and
     delivered to the undersigned at the address stated below. If such number of
     shares is not all of the shares purchasable pursuant to the attached
     Warrant, the undersigned requests that a new Warrant of like tenor for the
     balance of the remaining shares purchasable thereunder be delivered to the
     undersigned at the address stated below.

         In connection with the issuance of the Stock the undersigned hereby
     represents to the Company that he is acquiring the Stock for his own
     account for investment and not with a view to, or for resale in connection
     with, a distribution of the shares within the meaning of the Securities Act
     of 1933, as amended (the "Act"). The undersigned also understands that the
     Company has not registered the Stock under the Act, in reliance upon the
     private offering exemptions contained in Section 4(2) of the Act, and that
     such reliance is based in part upon the undersigned's representations.

         The undersigned understands that because the Stock has not been
     registered under the Act, the undersigned must hold such Stock indefinitely
     unless such Stock is subsequently registered and qualified under such
     statutes or it exempt from such registration and qualification. Before the
     undersigned makes any transfer or disposition of any shares of the Stock,
     the undersigned agrees to give to the Company written notice of its
     intention to do so and to describe briefly the manner of such proposed
     transfer or disposition unless (a) such transfer or disposition can be made
     without registration under the Act and qualification under the Law by
     reason of specific exemptions from such registration and such
     qualification, or (b) a registration statement has been filed pursuant to
     the Act and has been declared effective with respect to such disposition.

         The undersigned agrees that each certificate representing the Stock
     delivered to it shall bear substantially the following legend:

         "The shares represented by this certificate have not been registered
     under the Securities Act of 1933, as amended. The shares may not be sold or
     transferred in the absence of such registration or an exemption therefrom
     under said Act."

         The undersigned further agrees that the Company may place stop orders
     on the certificates evidencing the Stock with the transfer agent, if any,
     to the same effect as the above legend. The legend and stop transfer notice
     referred to above shall be

<PAGE>   7

     removed only upon the undersigned's furnishing to the Company an opinion
     of counsel (reasonably satisfactory to the Company) to the effect that
     such legend may be removed.
