                       COMMON STOCK SUBSCRIPTION AGREEMENT


                      SPATIALIZER AUDIO LABORATORIES, INC.


        THIS COMMON STOCK SUBSCRIPTION AGREEMENT (this "Agreement") is executed
in reliance upon the transaction exemption afforded by Regulation D as

"Common Stock") of Spatializer Audio Laboratories, Inc. (OTC Bulletin Board
symbol "SPAZ"), located at 20700 Ventura Boulevard, Suite 140, Woodland Hills,

Company, and the Company hereby represents and warrants to and agrees with
Subscriber, as follows:

        SECTION 1.    AGREEMENT TO SUBSCRIBE; PURCHASE PRICE.

               1.1 Closing. The Company will sell and Subscriber will buy, in
reliance upon the representations and warranties of the Company and Subscriber
contained in this Agreement, upon the terms and conditions hereinafter set
forth, shares of Common Stock for an aggregate purchase price of One Hundred
Thousand U.S. Dollars (US$100,000.00) (the "Aggregate Purchase Price") based on
the purchase price per share (the "Purchase Price") defined below. The number of
shares of Common Stock to be issued to Subscriber pursuant to this Agreement
shall be determined by dividing One Hundred Thousand U.S. Dollars
(US$100,000.00) by the Purchase Price, provided, however, that the Company shall
not issue to Subscriber a fraction of a share of Common Stock and shall instead
round the number of shares of Common Stock issued up to the next whole share of
Common Stock.

               1.2. Purchase Price. The Purchase Price shall be determined on
the Closing Date, and shall equal the average of the closing bid prices of
Common Stock for the ten (10) consecutive trading days ending one (1) trading
day prior to the Closing Date. The "closing bid price" shall mean the last bid
price for Common Stock on the OTC Bulletin Board, as reported by Bloomberg L.P.

               1.3 Form of Payment. Subscriber shall pay the Aggregate Purchase
Price by delivering immediately available funds in United States Dollars by wire
transfer to an account designated by the Company prior to the Closing Date
against delivery of the Common Stock and Warrants as payment in full for the
Securities.

not, and the consummation of the transactions contemplated hereby will not,

               (x)      Any private investment company with assets under
                        management in excess of US$________________________.

               2.9 No Registration, Review or Approval. Subscriber acknowledges
and understands that the limited private offering and sale of Securities
pursuant to this Agreement has not been reviewed or approved by the SEC or by
any state securities commission, authority or agency, and is not registered
under the Act or under the securities or "blue sky" laws, rules or regulations
of any state. Subscriber acknowledges, understands and agrees that the
Securities are being offered and sold hereunder pursuant to (i) a private
placement exemption to the registration provisions of the Act pursuant to
Section 3(b) or Section 4(2) of such Act and Regulation D promulgated under such
Act, and (ii) a similar exemption to the registration provisions of applicable
state securities laws. Subscriber understands that the Company is relying upon
the truth and accuracy of the representations, warranties, agreements,
acknowledgments and understandings of Subscriber set forth herein in order to
determine the applicability of such exemptions and the suitability of Subscriber
to acquire the Securities.

               2.10 Investment Intent. Without limiting its ability to resell
the Securities pursuant to an effective registration statement, Subscriber is
acquiring the Securities solely for its own account and not with a view to the
distribution, assignment or resale to others. Subscriber understands and agrees
that it may bear the economic risk of its investment in the Securities for an
indefinite period of time.

               2.11 No Advertisements. Subscriber is not subscribing for the
Securities as a result of or subsequent to any advertisement, article, notice or
other communication published in any newspaper, magazine, or similar media or
broadcast over television or radio, or presented at any seminar or meeting.

               2.12 Registration Rights. The parties have entered into a
Registration Rights Agreement (Exhibit B annexed hereto).

               2.13 Restricted Securities. Subscriber hereby confirms that it
has been informed that the Securities will be, when issued, restricted
securities under the Act and may not be resold or transferred unless first
registered under the federal securities laws or unless an exemption from such
registration is available with respect to a resale in the United States or in an
"offshore transaction" (as such term is defined in Regulations S under the Act).
Accordingly, Subscriber hereby acknowledges that it is prepared to hold the
Securities for an indefinite period. Subscriber is aware that Rule 144 and
Regulation S, promulgated under the Act, permit limited public resales of
securities acquired in non-public offerings, subject to the satisfaction of
certain conditions. Subscriber understands that under Rule 144 the conditions
include, among other things: the availability of certain current public
information about the issuer, the resale occurring not fewer than one (1) year
or two (2) years, as applicable, after the party has purchased and paid for the
securities to be sold, the sale being through a broker in an unsolicited
"broker's transaction" and the amount of securities being sold during any
three-month period not exceeding specified volume limitations. Subscriber
acknowledges and understands that the Company may not be satisfying the current
public information requirement of Rule 144 at the time Subscriber wishes to sell
the Securities, or other conditions under Rule 144 which are required of the
Company. Subscriber understands that



                                       5
<PAGE>   6

Regulation S, as currently in effect, allows resales in private and public
transactions in certain circumstances, only in qualified offshore transactions
and only when certain holding periods of at least one (1) year have been
fulfilled. Subscriber understands that he or she may be precluded from selling
any of the Securities under Rule 144 or Regulation S even if the holding periods
have been satisfied either because the other conditions may not have been
fulfilled or because markets for resales do not exist. Prior to its acquisition
of the Securities, Subscriber acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Securities.
Subscriber has such knowledge and experience in financial and business matters
as to make it capable of utilizing said information to evaluate the risks of the
prospective investment and to make an informed investment decision.

               2.14. Authorized Shares. Subscriber hereby acknowledges that, as
of the Closing Date, the Company may not be able to reserve from its authorized
but unissued shares of Common Stock a sufficient number of shares of Common
Stock to permit the exercise in full of all of the outstanding Warrants.
Subscriber understands that the Company is currently taking steps to increase
the number of authorized shares of Common Stock.

        SECTION 3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. For so long as
any Securities held by Subscriber remain outstanding, the Company acknowledges,
represents, warrants and agrees as follows:

               3.1 Organization/Qualification. The Company is a corporation duly
organized and validly existing under the laws of the State of Delaware and is in
good standing under such laws. The Company has all requisite corporate power and
authority to own, lease and operate its properties and assets, and to carry on
its business as presently conducted. The Company is qualified to do business as
a foreign corporation in each jurisdiction in which the ownership of its
property or the nature of its business requires such qualification, except where
failure to so qualify would not have a material adverse effect on the Company.

               3.2 Accuracy of Reports and Information. The Company is in
compliance, to the extent applicable, with all reporting obligations under
either Section 12(b), 12(g) or 15(d) of the 1934 Act, and shall maintain such
status on a timely basis. The Company has registered its Common Stock pursuant
to Section 12 of the 1934 Act and the Common Stock is listed and trades on the
OTC Bulletin Board. The Company has filed all material required to be filed
pursuant to all reporting obligations, under either Section 13(a) or 15(d) of
the 1934 Act for a period of at least twelve (12) months immediately preceding
the offer and sale of the Securities (or for such shorter period that the
Company has been required to file such material).

               3.3 SEC Filings/Full Disclosure. For a period of at least twelve
(12) months immediately preceding the Closing Date, to the Company's knowledge:
(i) none of the Company's filings with the SEC contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein in light of the circumstances under
which they were made, not misleading; and (ii) the Company has timely (after
giving effect to any filings on Form 12b-25) filed all requisite forms, reports
and exhibits thereto with the SEC.



                                       6
<PAGE>   7

               There is no fact known to the Company (other than general
economic conditions known to the public generally) that has not been publicly
disclosed by the Company or disclosed in writing to Subscriber which (i) could
reasonably be expected to have a material adverse effect on the condition
(financial or otherwise) or on earnings, business affairs, properties or assets
of the Company, or (ii) could reasonably be expected to materially and adversely
affect the ability of the Company to perform its obligations pursuant to this
Agreement.

               3.4 Authorization. The Company has all requisite corporate right,
power and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. All corporate action on the part of the
Company, its directors and stockholders necessary for the authorization,
execution, delivery and performance of this Agreement by the Company, the
authorization, sale, issuance and delivery of the Securities and the performance
of the Company's obligations hereunder has been taken. This Agreement has been
duly executed and delivered by the Company and constitutes a legal, valid and
binding obligation of the Company enforceable in accordance with its terms,
subject to laws of general application relating to bankruptcy, insolvency and
the relief of debtors and rules of law governing specific performance,
injunctive relief or other equitable remedies, and to limitations of public
policy as they may apply to the indemnification provisions set forth in this
Agreement. Upon their issuance and delivery pursuant to this Agreement, the
Securities will be validly issued, fully paid and non-assessable and will be
free of any liens or encumbrances; provided, however, that the Securities are
subject to restrictions on transfer under state and/or federal securities laws.
The issuance and sale of the Securities will not give rise to any preemptive
right or right of first refusal or right of participation on behalf of any
person.

               3.5 No Conflict. The execution and delivery of this Agreement do
not, and the consummation of the transactions contemplated hereby will not,
conflict with, or result in any violation of, or default under, or give rise to
a right of termination, cancellation or acceleration of any material obligation
or to a loss of a material benefit with respect to, any provision of the
Company's Certificate of Incorporation and any amendments thereto, Bylaws, or
any material mortgage, deed of trust, indenture, lease or other agreement or
instrument, permit, concession, franchise, license, judgment, order, decree
statute, law, ordinance, rule or regulation applicable to the Company, its
properties or assets, which would have a material adverse effect on the
Company's business and financial condition.

               3.6 No Undisclosed Liabilities or Events. The Company has no
liabilities or obligations other than those disclosed in the Reports, this
Agreement or those incurred in the ordinary course of the Company's business
since December 31, 1998, and which individually or in the aggregate, do not or
would not have a material adverse effect on the properties, business, condition
(financial or otherwise), results of operations or prospects of the Company. No
event or circumstance has occurred or exists with respect to the Company or its
properties, business, condition (financial or otherwise), results of operations
or prospects, which, under applicable law, rule or regulation, requires public
disclosure or announcement prior to the date hereof by the Company but which has
not been so publicly announced or disclosed.

               3.7 No Default. Except as set forth in this Agreement, the
Reports or on Schedule B annexed hereto, the Company is not in default in the
performance or observance of any material obligation, agreement, covenant or
condition contained in any indenture, mortgage, deed



                                       7

of trust or other material instrument or agreement to which it is a party or by
which it is or its property is bound, and neither the execution, nor the
delivery by the Company, nor the performance by the Company of its obligations
under this Agreement, including the exercise provision of the Securities, will
conflict with or result in the breach or violation of any of the terms or
provisions of, or constitute a default or result in the creation or imposition
of any lien or charge on any assets or properties of the Company under, any
material indenture, mortgage, deed of trust or other material agreement
applicable to the Company or instrument to which the Company is a party or by
which it is bound or any statute or the Certificate of Incorporation or Bylaws
of the Company, or any decree, judgment, order, rule or regulation of any court

Agreement, the Reports or on Schedule B annexed hereto, no default, as defined
in the respective agreement to which the Company is a party, and no event which,
with the giving of notice or the passage of time or both, would become a
default, has occurred and is continuing, which would have a material adverse
effect on the Company's business, properties, prospects, condition (financial or
otherwise) or results of operations.

               3.9 Governmental Consent, etc. No consent, approval or
authorization of, or designation, declaration or filing with, any governmental
authority on the part of the Company is required in connection with the valid
execution and delivery of this Agreement, or the offer, sale or issuance of the
Securities, or the consummation of any other transaction contemplated hereby,
except as may be required by applicable securities laws.

               3.10 Intellectual Property Rights. Except as disclosed in the

currently in existence; and there is no claim being made against the Company
regarding any trademark, trade name, patent, copyright, license, trade secret or
other intellectual property right which could have a material adverse effect on
the business or financial condition of the Company.

or material default under any of such agreements.

               3.12 Litigation. Except as disclosed in the Reports, there is no
action, proceeding or investigation pending, or to the Company's knowledge
threatened, against the Company which might result, either individually or in
the aggregate, in any material adverse change in the business, prospects,
conditions, affairs or operations of the Company. The Company is not a party to

               3.13 Title to Assets. Except as set forth in Reports, the Company
has good and marketable title to all properties and material assets described in
the Reports as owned by it, free and clear of any pledge, lien, security
interest, encumbrance, claim or equitable interest other than such as are not
material to the business of the Company.

               3.14 Subsidiaries. Except as disclosed in the Reports, the
Company does not presently own or control, directly or indirectly, any interest
in any other corporation, partnership, association or other business entity.

               3.15 Required Governmental Permits. The Company is in possession
of and operating in compliance with all authorizations, licenses, certificates,
consents, orders and permits from state, federal and other regulatory
authorities which are material to the conduct of its business, all of which are
valid and in full force and effect.

               3.16 Listing. The Company will use its best efforts to maintain
the listing of its Common Stock on the OTC Bulletin Board or another organized
United States market or quotation system. The Company has not received any
notice, oral or written, regarding continued listing and, as long as the Common
Stock and Warrants are outstanding, the Company will take no action which would
impact their continued listing or eligibility of the Company for such listing.

               3.17 Other Outstanding Securities/Financing Restrictions. Except
as disclosed in the Reports, the Company has no outstanding restricted shares,
or shares of Common Stock sold under Regulation S, Regulation D or outstanding
under any other exemption from registration, which are available for sale as
unrestricted ("free trading") stock.

               3.18 Registration Alternative. The Company covenants and agrees
that for so long as any of the Common Stock issuable upon exercise of the
Warrants remain outstanding and continue to be "restricted securities" within
the meaning of Rule 144 under the Act, the Company shall permit resales of the
underlying Common Stock pursuant to Rule 144 under the Act. The Company and
Subscriber shall provide the Company's transfer agent any and all papers
necessary to complete the transfer under Rule 144, including, but not limited
to, opinions of counsel to such transfer agent, and the Company shall continue
to file all material required to be filed pursuant to Sections 13(a) or 15(d) of
the 1934 Act.

               3.19 Capitalization. The authorized capital stock of the Company
consists of 50,000,000 shares of Common Stock, $0.01 par value per share, of
which 43,033,477 shares were outstanding as of December 14, 1999, and 1,000,000
shares of Preferred Stock, $0.01 par value per share, none of which are
outstanding as of the date hereof. All issued and outstanding shares of Common
Stock have been duly authorized and validly issued and are fully paid and
nonassessable.

               3.20 Dilution. The Company is aware and acknowledges that
exercise of the Warrant would cause dilution to existing stockholders and could
significantly increase the outstanding number of shares of Common Stock.

        SECTION 4. COVENANTS OF THE COMPANY. For so long as any Securities held
by Subscriber remain outstanding, the Company acknowledges, represents, warrants
and agrees as follows:

        (i)     The Company shall use its best efforts to reserve, prior to
                February 15, 2000, a sufficient number of shares of Common Stock
                from its authorized but unissued shares of Common Stock to
                permit the exercise in full of all of the outstanding Warrants.
                The Company is currently organizing a stockholder meeting to
                increase the number of authorized shares of Common Stock of the
                Company, and has filed with the SEC prior to the date hereof a
                preliminary proxy statement in connection with such stockholder
                meeting.

        (ii)    It will maintain the listing of its Common Stock on the OTC
                Bulletin Board.

        (iii)   It will permit Subscriber to exercise its right to exercise the
                Warrants by telecopying an executed and completed Notice of
                Exercise to the Company and delivering the original Notice of
                Exercise and the original Warrant to the Company by overnight
                courier. Each business date on which a Notice of Exercise is
                telecopied to and received by the Company in accordance with the
                provisions hereof shall be deemed an "Exercise Date". The
                Company will transmit the certificates representing shares of
                Common Stock issuable upon exercise of any Warrants (together
                with the certificates representing the Warrants not so
                exercised) to Subscriber via express courier, by electronic
                transfer or otherwise within three (3) business days after the
                Exercise Date if the Company has received the original Notice of
                Exercise and Warrant being exercised by such date. In addition
                to any other remedies which may be available to Subscriber, in
                the event that the Company fails to effect delivery of such
                shares of Common Stock within such three (3) business day
                period, Subscriber will be entitled to revoke the relevant
                Notice of Exercise by delivering a notice to such effect to the
                Company whereupon the Company and Subscriber shall each be
                restored to their respective positions immediately prior to
                delivery of such Notice of Exercise. The Notice of Exercise and
                Warrant representing the portion of the Warrant exercised shall
                be delivered as follows:

                To the Company:

                       Spatializer Audio Laboratories, Inc.
                       20700 Ventura Boulevard, Suite 140

        SECTION 5. RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Securities to the public without registration, the
Company agrees to:
<PAGE>   11

               (i)    make and keep public information available, as those terms
                      are understood and defined in Rule 144 under the Act, at
                      all times after the effective date on which the Company
                      becomes subject to the reporting requirements of the Act
                      or the 1934 Act;

               (ii)   file with the SEC in a timely manner all reports and other
                      documents required of the Company under the Act and the
                      1934 Act;

               (iii)  furnish to Subscriber forthwith, upon request, a written
                      statement by the Company as to its compliance with the
                      reporting requirements of said Rule 144, and of the Act
                      and the 1934 Act, a copy of the most recent annual or
                      quarterly report of the Company, and such other reports
                      and documents of the Company and other information in the
                      possession of or reasonably obtainable by the Company as
                      Subscriber may reasonably request in availing itself of
                      any rule or regulation of the SEC allowing Subscriber to
                      sell any such Securities without registration.

        SECTION 6. INDEMNIFICATION. The Company and Subscriber agree to
indemnify the other and to hold the other harmless from and against any and all
losses, damages, liabilities, costs and expenses (including reasonable
attorneys' fees and costs) which the other may sustain or incur in connection
with the breach by the indemnifying party of any representation, warranty or
covenant made by it in this Agreement.

        SECTION 7. REGISTRATION OR EXEMPTION REQUIREMENTS. Subscriber
acknowledges and understands that the Securities may not be resold or otherwise
transferred except in a transaction registered under the Act and any applicable
state securities laws, or unless an exemption from such registration is
available. Subscriber understands that the Securities will be imprinted with a
legend that prohibits the transfer of the Securities unless (i) they are
registered or such registration is not required, and (ii) if the transfer is
pursuant to an exemption from registration other than Rule 144 under the Act
and, if the Company shall so request in writing, an opinion of counsel
reasonably satisfactory to the Company is obtained to the effect that the
transaction is so exempt.

        SECTION 8. LEGEND. The certificates representing shares of Common Stock,
including shares of Common Stock to be issued upon exercise of the Warrants,
shall bear a legend restricting transfer under the Act, such legend to be
substantially as follows:

               THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT
               BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
               "ACT"). SUCH SECURITIES MAY NOT BE OFFERED OR SOLD OR TRANSFERRED
               IN THE UNITED STATES OR TO U.S. PERSONS IN THE ABSENCE OF SUCH
               REGISTRATION OR AN EXEMPTION THEREFROM UNDER THE ACT WHICH,
               EXCEPT IN THE CASE OF AN EXEMPTION PURSUANT TO RULE 144 UNDER THE
               ACT, IS CONFIRMED IN A LEGAL OPINION SATISFACTORY TO THE COMPANY.

The certificates representing these Securities, and each certificate issued in
transfer thereof, will also



                                       11
<PAGE>   12

bear any legend required under any applicable state securities law.

        SECTION 9. CLOSING DATE. The Closing Date hereunder shall be December
29, 1999, or such earlier date on or before December 31, 1999, on which the
terms and conditions hereof are satisfied (the "Closing Date"), and all acts,
deliveries and confirmations comprising the Closing Date regardless of
chronological sequence, shall be deemed to occur contemporaneously and
simultaneously, and such acts, deliveries, or confirmations shall not be
effective unless and until the last of same shall have occurred, and as shall be
mutually agreed upon as to time and place.

        SECTION 10. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL. Subscriber
understands that the Company's obligation to sell the Common Stock and Warrants
are conditioned upon:

                      payment in full for the purchase of the Securities;

               (iii)  All representations and warranties of Subscriber set forth
                      in this Agreement shall remain true and correct as of the
                      Closing Date; and

               (iv)   The sale and issuance of the Common Stock, Warrants, and
                      the proposed issuance of the Common Stock underlying the

approval of the other party; provided, however, that this provision shall not
apply to information which, at the time of disclosure, is already part of the
public domain (except by breach of this Agreement) and information which is
required to be disclosed by law. If for any reason the transactions contemplated
by this Agreement are not consummated, each of the parties hereto shall keep
confidential any information obtained from any other party, except information
publicly available or in such party's domain prior to the date hereof, and
except as required by court order and shall promptly return to the other parties
all schedules, documents, instruments, work papers or other written information,
without retaining copies thereof, previously furnished by it as a result of this
Agreement or in connection herewith.

               12.3 Facsimile/Counterparts/Entire Agreement. Except as otherwise

Exhibits hereto constitute the entire agreement between Subscriber and the
Company with respect to the subject matter hereof. This Agreement may be amended

illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that no such severability shall be
effective if it materially changes the economic benefit of this Agreement to any
party.

THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH SECURITIES MAY
NOT BE OFFERED OR SOLD OR TRANSFERRED IN THE UNITED STATES OR TO U.S. PERSONS IN
THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT WHICH,
EXCEPT IN THE CASE OF AN EXEMPTION PURSUANT TO RULE 144 UNDER SAID ACT, IS
CONFIRMED IN A LEGAL OPINION SATISFACTORY TO THE COMPANY.

                             STOCK PURCHASE WARRANT
                  To Purchase 200,000 Shares of Common Stock of

                      SPATIALIZER AUDIO LABORATORIES, INC.


        THIS STOCK PURCHASE WARRANT (this "Warrant") certifies that, for value

subject to the conditions hereinafter set forth, at any time after the date
hereof and on or prior to December 31, 2002 (the "Termination Date") but not

INC., a Delaware corporation (the "Company"), Two Hundred Thousand (200,000)
shares of Common Stock (the "Warrant Shares"). The purchase price of one share
of Common Stock (the "Exercise Price") under this Warrant shall be Sixty-Seven
United States Cents (US$0.67). The Exercise Price and the number of shares for
which the Warrant is exercisable shall be subject to adjustment as provided
herein. This Warrant is being issued in connection with the Common Stock
Subscription Agreement (the "Agreement"), dated as of December 29, 1999, in the
amount of One Hundred Thousand United States Dollars (US$100,000) between the
Company and the Investor and is subject to its terms. Capitalized terms not
otherwise defined herein shall have that meaning as set forth in the Agreement.
In the event of any conflict between the terms of this Warrant and the
Agreement, the Agreement shall control.

        1. Title of Warrant. This Warrant shall be issued in the name of the
Investor. This Warrant is not transferable.

        2. Authorization of Shares. The Company covenants that all shares of

authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

        3. Exercise of Warrant. Exercise of the purchase rights represented by
this Warrant may be made at any time or times one day after the date hereof, in
whole or in part, before the close of business on the Termination Date, or such
earlier date on which this Warrant may terminate as provided in Section 12
below, by the surrender of this Warrant and the Notice of Exercise annexed
hereto duly executed, at the office of the Company (or such other office or
agency of the Company as it may designate by notice in writing to the Investor
at the address of the Investor appearing on the books of the Company) and upon
payment of the Exercise Price of the shares thereby purchased; whereupon the
Investor shall be entitled to receive a certificate for the number of shares of
Common



<PAGE>   20

Stock so purchased. Certificates for shares purchased hereunder shall be
delivered to the Investor within five business days after the date on which this
Warrant shall have been exercised as aforesaid. Payment of the Exercise Price of
the shares may be by certified check or cashier's check or by wire transfer to
an account designated by the Company in an amount equal to the Exercise Price
multiplied by the number of shares being purchased.

        4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.

        5. Charges, Taxes and Expenses. Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the Investor for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the Investor.

        6.     Restrictions on Transfer of Warrant Shares.

               (a) Warrant Shares may not be sold, transferred, pledged,
hypothecated or otherwise disposed of except in accordance with applicable
federal and state securities laws.

               (b) Unless the Warrant Shares have been registered under the Act,
or are exempt from registration, upon exercise of the Warrant or any portion
thereof and the issuance of any Warrant Shares, all certificates representing
Warrant Shares shall bear on the face thereof substantially the following
legend:

               THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT
               BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
               "ACT"). SUCH SECURITIES MAY NOT BE OFFERED OR SOLD OR TRANSFERRED
               IN THE UNITED STATES OR TO U.S. PERSONS IN THE ABSENCE OF SUCH
               REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT WHICH,
               EXCEPT IN THE CASE OF AN EXEMPTION PURSUANT TO RULE 144 UNDER
               SAID ACT, IS CONFIRMED IN A LEGAL OPINION SATISFACTORY TO THE
               COMPANY.

The Investor agrees and acknowledges that this Warrant is being purchased for
its own account, for investment purposes only, and not for the account of any
other person, and not with a view to distribution, assignment, pledge or resale
to others or to fractionalization in whole or in part. The Investor further
represents, warrants and agrees as follows: no other person has or will have a
direct or indirect beneficial interest in this Warrant and the Investor will not
sell, hypothecate or otherwise transfer the Warrant except in accordance with
the Act thereunder and applicable state securities laws or unless, in the
opinion of counsel for the Investor acceptable to the Company, an exemption from
the registration requirements of the Act and such laws is available.

        7. Closing of Books. The Company will at no time close its stockholder
books or records in any manner which interferes with the timely exercise of this
Warrant.



<PAGE>   21

        8. No Rights as Stockholder until Exercise. This Warrant does not
entitle the Investor to any voting rights or other rights as a stockholder of
the Company prior to the exercise thereof. If, however, at the time of the
surrender of this Warrant and purchase of Warrant Shares the Investor shall be
entitled to exercise this Warrant, the shares so purchased shall be and be
deemed to be issued to the Investor as the record owner of such shares as of the
close of business on the date on which this Warrant shall have been exercised.

        9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
represents and warrants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant,
and in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and upon reimbursement to the Company of all reasonable
expenses incidental thereto, and upon surrender and cancellation of such
Warrant, if mutilated, the Company will make and deliver a new Warrant of like
tenor and dated as of such cancellation, in lieu of this Warrant.

        10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

        11.    Effect of Certain Events.

               (a) If at any time the Company proposes to sell or otherwise
convey all or substantially all of its assets, a sale in which the consideration
to be received by the Company or its stockholders consists solely of cash, the
Company shall give the Investor thirty (30) days' notice of the proposed
effective date of the transaction specifying that the Warrant shall terminate if
the Warrant has not been exercised by the effective date of the transaction.

               (b) In case the Company shall at any time effect any merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities of the Company or another entity, or other property, the
Investor shall have the right thereafter to purchase, by exercise of this
Warrant and payment of the aggregate Exercise Price in effect immediately prior
to such action, the kind and amount of shares and other securities and property
which it would have owned or have been entitled to receive after the happening
of such transaction had this Warrant been exercised immediately prior thereto.

               (c) The Investor shall be granted registration rights for the
Warrant Shares pursuant to a Registration Rights Agreement dated of even date
herewith.

        12. Adjustments of Exercise Price and Number of Warrant Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following:

        In case the Company shall (i) declare or pay a dividend in shares of
Common Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide



<PAGE>   22

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 any
shares of its capital stock in a reclassification of the Common Stock, then, in
such events, the number of Warrant Shares purchasable upon exercise of this
Warrant immediately prior thereto shall be adjusted so that the Investor shall
be entitled to receive the kind and number of Warrant Shares or other securities
of the Company which he would have owned or have been entitled to receive had
such Warrant been exercised in advance thereof. An adjustment made pursuant to
this Section 12 shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

        13. Voluntary Adjustment by the Company. The Company may at its
discretion, at any time during the term of this Warrant, reduce the then current
Exercise Price to any amount and for any period of time deemed appropriate by
the Board of Directors of the Company.

        14. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the Investor notice of such adjustment or adjustments setting forth the
number of Warrant Shares (and other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares after
such adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth computation by which such adjustment was made. Such
notice, in absence of manifest error, shall be conclusive evidence of the
correctness of such adjustment.

        15. Authorized Shares. The Investor hereby acknowledges that, as of the
Closing Date (as defined in the Agreement), the Company may not be able to
reserve from its authorized but unissued shares of Common Stock a sufficient
number of shares of Common Stock to permit the exercise in full of all of the
outstanding Warrants. The Company shall use its best efforts to reserve, prior
to February 15, 2000, a sufficient number of shares of Common Stock from its
authorized but unissued shares of Common Stock to permit the exercise in full of
all of the outstanding Warrants. The Company covenants that, after such time as
it has increased the number of authorized shares of Common Stock and for the
remainder of the period the Warrant is outstanding, it will reserve from its
authorized and unissued Common Stock a sufficient number of shares to provide
for the issuance of the Warrant Shares upon the exercise of any rights under
this Warrant. Subject to the foregoing, the Company further covenants that its
issuance of this Warrant shall constitute full authority to its officers who are
charged with the duty of executing stock certificates to execute and issue the
necessary certificates for shares of the Company's Common Stock upon the
exercise of the purchase rights under this Warrant. The Company will take all
such reasonable action as may be necessary to assure that such shares of Common
Stock may be issued as provided herein without violation of any applicable law
or regulation, or of any requirements of the OTC Bulletin Board or any domestic
securities exchange upon which the Common Stock may be listed.

        16.    Miscellaneous.

               (a) Issue Date; Jurisdiction. The provisions of this Warrant
shall be construed and shall be given effect in all respects as if it had been
issued and delivered by the Company on the



<PAGE>   23

date hereof. This Warrant shall be binding upon any successors or assigns of the
parties hereto. This Warrant shall constitute a contract under the laws and
jurisdiction of California and for all purposes shall be construed in accordance
with and governed by the laws of said state without regard to its conflict of
law, principles or rules.

               (b) Restrictions. The Investor acknowledges that the Common Stock
acquired upon the exercise of this Warrant, if not registered, may have
restrictions upon its resale imposed by state and federal securities laws.

               (c) Modification and Waiver. This Warrant and any provisions
hereof may be changed, waived, discharged or terminated only by an instrument in
writing signed by the party against which enforcement of the same is sought.

               (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the Investor or the Company shall be
delivered or shall be sent by certified or registered mail, postage prepaid, to
the Investor at its address as shown on the books of the Company or to the
Company at the address set forth in the Agreement.

                          Registration Rights Agreement



<PAGE>   27

                          REGISTRATION RIGHTS AGREEMENT


        THIS REGISTRATION RIGHTS AGREEMENT, dated the 29th day of December,
1999, between LUFENG INVESTMENTS (the "Holder"), and SPATIALIZER AUDIO
LABORATORIES, INC., a Delaware corporation having its principal place of
business at 20700 Ventura Boulevard, Suite 140, Woodland Hills, California 91364
(the "Company").

        WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Holder is purchasing from the Company, pursuant to that certain
Common Stock Subscription Agreement (the "Subscription Agreement"), dated of
even date herewith, One Hundred Seventy-Nine Thousand Four Hundred Fifty-Three
(179,453) shares of Common Stock, and a Warrant to purchase an aggregate of Two
Hundred Thousand (200,000) shares of Common Stock. The shares of Common Stock of
the Company underlying the Warrants acquired by the Holder or the other
purchasers are referred to as the "Warrant Shares" (capitalized terms defined in
the Subscription Agreement and not otherwise defined herein have the meanings
specified in the Subscription Agreement); and

        WHEREAS, the Company desires to grant to the Holder the registration
rights set forth herein.

        NOW, THEREFORE, the parties hereto mutually agree as follows:

        Section 1. Registrable Securities. As used herein the term "Registrable
Securities" means the shares of Common Stock subscribed for and purchased by the
Holder pursuant to the Subscription Agreement, and the Warrant Shares; provided,
however, that with respect to any particular Registrable Security, such security
shall cease to be a Registrable Security when, as of the date of determination,
(i) it has been effectively registered under the Securities Act of 1933, as
amended (the "Act") and disposed of pursuant thereto, (ii) registration under
the Act is no longer required for the immediate public distribution of such
security as a result of the provisions of Rule 144, or (iii) it has ceased to be
outstanding. In the event of any merger, reorganization, consolidation,
recapitalization or other change in corporate structure affecting the Common
Stock, such adjustment shall be made in the definition of Registrable Security
as is appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Section 1.

        Section 2. Restrictions on Transfer. The Holder acknowledges and
understands that prior to the registration of the Registrable Securities as
provided herein, the Registrable Securities are "restricted securities" as
defined in Rule 144 promulgated under the Act. The Holder understands that no
disposition or transfer of the Registrable Securities may be made by Holder in
the absence of (i) an opinion of counsel reasonably satisfactory to the Company
that such transfer may be made or (ii) a registration statement under the Act is
then in effect with respect thereto.

        Section 3.    Registration Rights.

               (a) The Company agrees that it will prepare and file with the
Securities and Exchange Commission (the "SEC"), within thirty (30) days after
the date hereof, a registration statement on Form S-3 or if the Company is not
eligible to use such Form S-3, another appropriate



<PAGE>   28

form of registration statement (the "Registration Statement"), at the sole
expense of the Company (except as provided in Section 3(c) hereof), in respect
of Holder's Registrable Securities, so as to permit resale of the Registrable
Securities under the Act. The Company agrees that it will cause the Registration
Statement to become effective by April 15, 2000. The number of securities to be
registered shall include all of Holder's Registrable Securities.

               (b) The Company will maintain the Registration Statement or
post-effective amendment filed under this Section 3 hereof current under Act
until the earlier of (i) the date that all of the Registrable Securities have
been sold pursuant to the Registration Statement, (ii) the date that the
Registrable Securities may be sold under the provisions of Rule 144 or (iii)
three (3) years after the effective date of the Registration Statement (the
"Effective Date").

               (c) All fees, disbursements and out-of-pocket expenses and costs
incurred by the Company in connection with the preparation and filing of the
Registration Statement under Section 3(a) and in complying with applicable
securities and Blue Sky laws (including, without limitation, all attorneys'
fees) shall be borne by the Company. The Holder shall bear the costs of
underwriting discounts and commissions, if any, applicable to the Registrable
Securities being registered on its behalf and all of the other fees and expenses
of such registration, including of its counsel and such other expenses as are
necessary to qualify the sale of Registrable Securities in compliance with any
state Blue Sky laws. The Company shall use its best efforts to qualify any of
the securities for sale in such states as the Holder reasonably designates and
shall furnish indemnification in the manner provided in Section 9 hereof.
However, the Company shall not be required to qualify the Registrable Securities
in any state or jurisdiction which will require an escrow or other restriction
relating to the Company and/or the sellers, or where the Company would be
required to qualify as a dealer in securities under the securities or blue sky
laws of such state or jurisdiction. The Company at its expense will supply the
Holder with copies of such Registration Statement and the prospectus or offering
circular included therein and other related documents in such quantities as may
be reasonably requested by the Holder.

               (d) The Company shall not be required by this Section 3 to
include Holder's Registrable Securities in the Registration Statement which is
to be filed if, in the opinion of counsel for both the Holder and the Company
(or, should they not agree, in the opinion of another counsel experienced in
securities law matters acceptable to counsel for the Holder and the Company),
the proposed offering or other transfer as to which such registration is
requested is exempt from applicable federal and state securities laws and would
result in all purchasers or transferees obtaining securities which are not
restricted securities, as defined in Rule 144 under the Act.

               (e) No provision contained herein shall preclude the Company from
selling securities pursuant to any registration statement in which it is
required to include Registrable Securities pursuant to this Section 3.

        Section 4. Cooperation with Company. Holder will cooperate with the
Company in all respects in connection with this Agreement, including, timely
supplying all information reasonably requested by the Company and executing and
returning all documents reasonably requested in connection with the registration
and sale of the Registrable Securities.



<PAGE>   29

        Section 5. Registration Procedures. Whenever the Company is required by
the provisions of this Agreement to effect the registration of any of the
Registrable Securities under the Act, the Company shall (except as otherwise
provided in this Agreement), as expeditiously as possible:

               (a) prepare and file with the SEC such amendments and supplements
to such registration statement and the Prospectus used in connection therewith
as may be necessary to keep such registration statement effective as per Section
3(b) herein and to comply with the provisions of the Act with respect to the
sale or other disposition of all securities covered by such registration
statement when the Holder of such securities shall desire to sell or otherwise
dispose of the same (including prospectus supplements with respect to the sales
of securities from time to time in connection with a registration statement
pursuant to Rule 415 under the Act);

               (b) furnish to the Holder such numbers of copies of a summary
prospectus or other prospectus, including a preliminary prospectus or any
amendment or supplement to any prospectus, in conformity with the requirements
of the Act, and such other documents, as such Holder may reasonably request in
order to facilitate the public sale or other disposition of the securities owned
by such Holder;

               (c) use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or blue sky
laws of such jurisdictions as the Holder shall reasonably request, and do any
and all other acts and things which may be necessary or advisable to enable the
Holder to consummate the public sale or other disposition in such jurisdiction
of the securities owned by the Holder; provided, however, that: (i) the Company
shall not for any such purpose be required to qualify to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified or to
file therein any general consent to service of process, and (ii) the Company
shall not be obligated to take any action to effect any such registration,
qualification or compliance pursuant to this Section 5(c) in any jurisdiction in
which the Company would be required to qualify as a dealer in securities under
the securities or blue sky laws of such jurisdiction.

               (d) list such securities on the OTC Bulletin Board or any
securities exchange on which any securities of the Company is then listed, if
the listing of such securities is then permitted under the rules of such
exchange;

               (e) enter into and perform its obligations under an underwriting
agreement, if the offering is an underwritten offering, in usual and customary
form, with the managing underwriter or underwriters of such underwritten
offering;

               (f) notify each Holder of Registrable Securities covered by such
registration statement, at any time when a prospectus relating thereto covered
by such registration statement is required to be delivered under the Act, of the
happening of any event of which it has knowledge as a result of which the
prospectus included in such registration statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing.



<PAGE>   30

        Section 6. Assignment. The rights granted the Holder under this
Agreement shall not be assigned. This Agreement is binding upon and inures to
the benefit of the parties hereto and their respective heirs, successors and
permitted assigns.

        Section 7. Termination of Registration Rights. The rights granted
pursuant to this Agreement shall terminate as to the Holder upon the occurrence
of any of the following:

               (a)      all of the Holder's securities subject to this Agreement
                        have been registered;

               (b)      such Holder's securities subject to this Agreement may
                        be sold without such registration pursuant to Rule 144
                        promulgated by the SEC pursuant to the Act;

               (c)      such Holder's securities subject to this Agreement can
                        be sold pursuant to Rule 144(k).

        Section 8.    Indemnification.

               (a) The Company agrees to indemnify and hold harmless the Holder
and each person, if any, who controls Holder within the meaning of the Act
("Distributing Holders") against any losses, claims, damages or liabilities,
joint or several (which shall, for all purposes of this Agreement, include, but
not be limited to, all costs of defense and investigation and all attorneys'
fees), to which the Distributing Holder may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in the Registration Statement,
or any related preliminary prospectus, final prospectus, offering circular,
notification or amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in the Registration Statement, preliminary prospectus, final
prospectus, offering circular, notification or amendment, or supplement thereto
in reliance upon, and in conformity with, written information furnished to the
Company by the Distributing Holders, specifically for use in the preparation
thereof. This Section shall not inure to the benefit of any Distributing Holder
with respect to any person asserting such loss, claim, damage or liability who
purchased the Registrable Securities which are the subject thereof if the
Distributing Holder failed to send or give (in violation of the Act or the rules
and regulations promulgated thereunder) a copy of the prospectus contained in
the Registration Statement to such person at or prior to the written
confirmation to such person of the sale of such Registrable Securities, where
the Distributing Holder was obligated to do so under the Act or the rules and
regulations promulgated hereunder. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

               (b) Each Distributing Holder agrees that it will indemnify and
hold harmless the Company, and each officer, director of the Company or person,
if any, who controls the Company within the meaning of the Act, against any
losses, claims, damages or liabilities (which shall, for all



<PAGE>   31

purposes of this Agreement, include, but not be limited to, all costs of defense
and investigation and all attorneys' fees) to which the Company or any such
officer, director or controlling person may become subject under the Act or
otherwise, insofar as such losses claims, damages or liabilities (or actions in
respect thereof); arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in the Registration Statement
prepared by the Company, or any related preliminary prospectus, final
prospectus, offering circular, notification or amendment or supplement thereto,
or arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, but in each case only to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in such Registration Statement, preliminary prospectus, final prospectus,
offering circular, notification or amendment or supplement thereto in reliance
upon, and in conformity with, written information furnished to the Company by
such Distributing Holder, specifically for use in the preparation thereof. This
indemnity agreement will be in addition to any liability which the Distributing
Holders may otherwise have.

               (c) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve the
indemnifying party from any liability which it may have to any indemnified party
otherwise than as to the particular item as to which indemnification is then
being sought solely pursuant to this Section. In case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate in,
and, to the extent that it may wish, jointly with any other indemnifying party
similarly notified, assume the defense thereof, subject to the provisions herein
stated and after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party will not
be liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation, unless the
indemnifying party shall not pursue the action to its final conclusion. The
indemnified party shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall not be at the expense of the indemnifying party if the
indemnifying party has assumed the defense of the action with counsel reasonably
satisfactory to the indemnified party; provided that if the indemnified party is
the Distributing Holder, the fees and expenses of such counsel shall be at the
expense of the indemnifying party if (i) the employment of such counsel has been
specifically authorized in writing by the indemnifying party, or (ii) the named
parties to any such action (including any impleaded parties) include both the
Distributing Holder and the indemnifying party and the Distributing Holder shall
have been advised by such counsel that there may be one or more legal defenses
available to the indemnifying party different from or in conflict with any legal
defenses which may be available to the Distributing Holder (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the Distributing Holder, it being understood, however, that the
indemnifying party shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable only for the reasonable
fees and expenses of one separate firm of attorneys for the Distributing Holder,
which firm shall be designated in



<PAGE>   32

writing by the Distributing Holder). No settlement of any action against an
indemnified party shall be made without the prior written consent of the
indemnified party, which consent shall not be unreasonably withheld.

        Section 9. Contribution. In order to provide for just and equitable
contribution under the Act in any case in which (i) the Distributing Holder, or
the Company, makes a claim for indemnification, but is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that the express provisions of this Agreement provide for indemnification in
such case, or (ii) contribution under the Act may be required on the part of any
Distributing Holder, or the Company, then the Company and the applicable
Distributing Holder shall contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (which shall, for all purposes of this
Agreement, include, but not be limited to, all costs of defense and
investigation and all attorneys' fees), in either such case (after contribution
from others) on the basis of relative fault as well as any other relevant
equitable considerations. The relative fault shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or the applicable
Distributing Holder, on the other hand, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Distributing Holder agree that it
would not be just and equitable if contribution pursuant to this Section were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in this
Section. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages or liabilities (or actions in respect thereof) referred
to above in this Section shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.

        Section 10. Notices. Any notice pursuant to this Agreement by the
Company or by the Holder shall be in writing and shall be deemed to have been
duly given if delivered by (i) hand, (ii) by facsimile and followed by mail
delivery or (iii) if mailed by certified mail, return receipt requested, postage
prepaid, addressed as follows:

               (a)    If to the Holder, to its address set forth herein.

               (b) If to the Company, at the address set forth herein, or to
such other address as any such party may designate by notice to the other party.
Notices shall be deemed given at the time they are delivered personally or five
(5) days after they are mailed in the manner set forth above. If notice is
delivered by facsimile and followed by mail, delivery shall be deemed given two
(2) days after such facsimile is sent.

        Section 11. "Piggy-Back" Registration. The Holder shall have the right
to include the Registrable Securities as part of any registration of securities
filed by the Company (other than in connection with a transaction contemplated
by Rule 145(a) promulgated under the Act or pursuant



<PAGE>   33

to Form S-8) and must be notified in writing of such filing; provided, however,
that the Holder agrees it shall not have any piggy-back registration rights
pursuant to this Section if the Registrable Securities may be sold in the United
States pursuant to the provisions of Rule 144. The Holder shall have five (5)
business days to notify the Company in writing as to whether the Company is to
include the Holder or not include the Holder as part of the registration;
provided, however, that if any registration pursuant to this Section shall be
underwritten, in whole or in part, the Company may require that the Registrable
Securities requested for inclusion pursuant to this Section be included in the
underwriting on the same terms and conditions as the securities otherwise being
sold through the underwriters. If in the good faith judgment of the underwriter
evidenced in writing of such offering only a limited number of Registrable
Securities should be included in such offering, or no such shares should be
included, the holder, and all other selling stockholders, shall be limited to
registering such proportion of their respective shares as shall equal the
proportion that the number of shares of selling stockholders permitted to be
registered by the underwriter in such offering bears to the total number of all
shares then held by all selling stockholders desiring to participate in such
offering. Those Registrable Securities which are excluded from an underwritten
offering pursuant to the foregoing provisions of this Section (and all other
Registrable Securities) shall be withheld from the market by the holders thereof
for a period, not to exceed one hundred eighty (180) days, which the underwriter
may reasonably determine is necessary in order to effect such underwritten
offering. The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section prior to the effectiveness of
such registration. All registration expenses incurred by the Company in
complying with this Section shall be paid by the Company, exclusive of
underwriting discounts, commissions and legal fees and expenses for counsel to
the Holder.

        Section 12. Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

        Section 13. Headings. The headings in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

        Section 14. Governing Law, Venue. This Agreement will be construed and
enforced in accordance with and governed by the laws of the State of California,
except for matters arising under the Act, without reference to principles of
conflicts of law. Each of the parties consents to the jurisdiction of the
federal courts whose districts encompass any part of the State of California or
the state courts of the State of California in connection with any dispute
arising under this Agreement and hereby waives, to the maximum extent permitted
by law, any objection, including any objection based on forum non conveniens, to
the bringing of any such proceeding in such jurisdictions. Each party hereby
agrees that if another party to this Agreement obtains a judgment against it in
such a proceeding, the party which obtained such judgment may enforce same by
summary judgment in the courts of any state or country having jurisdiction over
the party against whom such judgment was obtained, and each party hereby waives
any defenses available to it under local law and agrees to the enforcement of
such a judgment. Each party to this Agreement irrevocably consents to the
service of process in any such proceeding by the mailing of copies thereof by
registered or certified mail, postage prepaid, to such party at its address set
forth herein. Nothing herein shall affect the right of any party to serve
process in any other manner permitted by law.

        Section 15. Severability/Defined Terms. If any provision of this
Agreement shall for any reason be held invalid or unenforceable, such invalidity
or unenforceability shall not affect any other provision hereof and this
Agreement shall be construed as if such invalid or unenforceable provision had
never been contained herein. Terms not otherwise defined herein shall be defined
in accordance with the Subscription Agreement.
