                                    ARTICLE 2
                               RESALE REGISTRATION

         The Company hereby agrees to file a registration statement permitting
the sale of the Eligible Securities by the Stockholders to the public under the
Securities Act not later than 90 days after the earlier of the Mandatory
Conversion Date (as such term is defined in Section 3(a)(ii) of the Convertible
Note or the date on which more than fifty (50%) percent of the aggregate
principal of the series of Convertible Notes have been converted into equity
(the "Converted Securities") ("Resale Registration Statement"). The Company
shall have the right to include in any such Resale Registration Statement any
other securities of the Company, including, but not limited to, any securities
of the Company (the "Earlier Securities") desired to be registered by persons or
entities also having registration rights granted by the Company. Notwithstanding
the foregoing, the Company's obligation to file a Resale Registration Statement
with respect to any shares of Common Stock issued on conversion of any
Convertible Notes shall terminate and become null and void once such shares are
permitted to be sold under Rule 144 or any successor provision of the Securities
Act.

                                    ARTICLE 3
                               DEMAND REGISTRATION

         3.1 Requests for Registration. At any time after the earlier of (a)
June 30, 2001 and (b) one year after an automatic conversion described in
Section 3(a)(ii) of the Convertible Notes, the holders of at least a majority of
the Eligible Securities then deemed outstanding may, on not more than one
occasion during the term of this Agreement, request registration on Form S-3 or
a successor thereto under the Securities Act of all or part of their Eligible
Securities for purposes of conducting an underwritten offering thereof. Any
registration requested pursuant to this Paragraph 3.1 is referred to herein as a
"Demand Registration." The request for a Demand Registration shall specify the
approximate number of Eligible Securities requested to be registered and the
anticipated per share price range for such offering.

         3.2 Notice to Other Holders. Within ten days after receipt of a request
for a Demand Registration, the Company shall give written notice thereof to all
the other holders of Eligible Securities then deemed outstanding. Each of the
other holders shall have the right, within 15 Business Days after the delivery
of such notice, to request that the Company include all or a portion of such
holder's Eligible Securities in such Demand Registration.

         3.3 Permitted Demand Registrations. The Stockholders shall be entitled
to request the Demand Registration only if (a) the aggregate offering value of
the Eligible Securities requested to be registered in any such registration
equals at least $1,000,000 and (b) Form S-3 is available for such offering by
the Stockholders. A registration shall not count as a permitted Demand
Registration until it has become effective (unless the Demand

                                       3
<PAGE>   4
Registration has not become effective due solely to the fault of the holders
requesting such registration).

         3.4 Priority on Demand Registrations. The Company shall not include in
any Demand Registration any securities that are not Eligible Securities without
the prior written consent of the Selling Stockholders of at least a majority of
the Eligible Securities included in such registration, provided, however, that
no consent of the Selling Stockholders shall be needed to include securities as
to which Argyle Capital Management Corporation ("Argyle") has a piggy-back
registration right. If the managing underwriters in a Demand Registration advise
the Company in writing that in their opinion the number of Eligible Securities
and, if permitted hereunder, other securities requested to be included in such
offering, exceeds the number of Eligible Securities and other securities, if
any, which can be sold in an orderly manner in such offering within a price
range acceptable to the Selling Stockholders of a majority of the Eligible
Securities initially requesting registration, the Company shall include in such
registration, first, the number of Eligible Securities requested to be included
by Selling Stockholders that initially requested such registration which in the
opinion of such underwriters can be sold in an orderly manner within the price
range of such offering, pro rata among such Selling Stockholders on the basis of
the amount of Eligible Securities owned by each such Selling Stockholder,
second, the number of Eligible Securities requested to be included by Selling
Stockholders that elected to participate in such registration pursuant to
Section 3.2 which in the opinion of such underwriters can be sold in an orderly
manner within the price range of such offering, pro rata among such Selling
Stockholders on the basis of the amount of Eligible Securities owned by each
such Selling Stockholder, and third, the number of securities that are not
Eligible Securities that are held by Argyle or that the Selling Stockholders
agreed to include in such registration as provided above which in the opinion of
such underwriters can be sold in an orderly manner within the price range of
such offering, pro rata among such the Persons holding such securities on the
basis of the amount of such securities owned by each such Person.

         3.5 Deferral of Registration Demand in the Event of Company Offering.
In the event that prior to the time a Demand Registration is requested the
Company has in good faith commenced the preparation of a registration statement
for an underwritten offering of its securities (a "Company Offering") and the
managing underwriter delivers a written opinion (a "Transaction Deferral
Opinion") to the requesting Stockholders stating, in its good faith opinion,
that the proposed offering pursuant to the Demand Registration will materially
and adversely affect the Company Offering, then the Company will be permitted to
defer the filing of the registration statement pursuant to the Demand
Registration until the earliest of (a) the abandonment of the Company Offering,
(b) 90 days after receipt by the requesting Stockholders of the Transaction
Deferral Opinion (unless the Company Offering has become effective on or prior
to such 90th day) and (c) if the Company Offering has become effective on or
prior to such 90th day, 120 days after the effective date of the Company
Offering (or such shorter period as may be requested by the managing underwriter
for the Company Offering). The Company will not be permitted to defer a Demand
Registration pursuant to this Paragraph 3.5 more than once

                                       4
<PAGE>   5
in any 12-month period. If the Company defers any registration statement
pursuant to this Paragraph 3.5 and the requesting Stockholders determine not to
proceed with such registration on or prior to the end of the permitted deferral
period, the registration shall not be counted as a permitted Demand Registration
hereunder. Notwithstanding the foregoing, if a Demand Registration is made
within 60 days prior to the end of the Company's then current fiscal year and
such registration is to be effected other than on Form S-3 or other comparable
form for the registration of securities, the Company will have the right to
delay the filing of a registration statement for 150 days or until the Company
receives its audited financial statements for such fiscal year, whichever occurs
first.

         3.6 Restrictions on Registration. The Company shall not be obligated to
effect any Demand Registration within 120 days after the effective date of a
registration involving an underwritten public offering by the Company and in
which the Stockholders were given piggyback rights pursuant to Article 4 and in
which there was no reduction in the number of Eligible Securities requested to
be included. The Company may postpone for up to 120 days the filing or the
effectiveness of a registration statement for a Demand Registration if the
Company's board of directors determines in its reasonable good faith judgment
that such Demand Registration would reasonably be expected to have a material
adverse effect on any proposal or plan by the Company to engage in any
acquisition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer, reorganization or similar transaction;
provided that in such event, the Stockholders initially requesting such Demand
Registration shall be entitled to withdraw such request and, if such request is
withdrawn, the Demand Registration shall not count as a Demand Registration
hereunder. The Company may delay a Demand Registration hereunder only once in
any twelve-month period.

         3.7 Selection of Underwriters. The holders of a majority of the
Eligible Securities initially requesting registration hereunder shall have the
right to select the investment banker(s) and manager(s) to administer the
offering, if any, subject to the Company's approval which shall not be
unreasonably withheld. All Stockholders proposing to distribute Eligible
Securities through the offering shall (together with the Company) enter into an
underwriting agreement in customary form with the selected investment banker(s)
and manager(s).

                                    ARTICLE 4
                             PIGGYBACK REGISTRATION

         4.1 Right to Piggyback. Commencing on the date hereof, whenever the
Company proposes to register any of its securities under the Securities Act for
an underwritten public offering (other than pursuant to a Demand Registration)
and the registration form to be used may be used for the registration of
Eligible Securities (a "Piggyback Registration"), the Company shall give prompt
written notice (in any event within 15 Business Days after its receipt of notice
of any exercise of demand registration rights other than under this Agreement)
to all holders of Eligible Securities then deemed

                                       5
<PAGE>   6
outstanding of its intention to effect such a registration and shall include in
such registration all Eligible Securities with respect to which the Company has
received written requests for inclusion therein within 15 Business Days after
delivery of the Company's notice. Notwithstanding the foregoing, the Company
shall not be required to effect any registration of Eligible Securities under
this Paragraph 4.1 incidental to the registration of any of its securities in
connection with mergers, acquisitions, exchange offers, subscription offers or
dividend reinvestment plans.

         4.2 Priority on Primary Registrations. If a Piggyback Registration is
an underwritten primary registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in an orderly manner in such offering within a price range
acceptable to the Company, the Company will include in such registration (i)
first, the securities the Company proposes to sell, (ii) second, the Eligible
Securities requested to be included in such registration, pro rata among the
holders of such Eligible Securities on the basis of the number of shares owned
by each such holder, and (iii) third, other securities requested to be included
in such registration.

         4.3 Priority on Secondary Registrations. If a Piggyback Registration is
an underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the holders initially requesting
such registration, the Company shall include in such registration (i) first, the
securities requested to be included therein by the holders requesting such
registration, (ii) second, the Eligible Securities requested to be included in
such registration, pro rata among the holders of such Eligible Securities on the
basis of the number of shares owned by each such holder, and (iii) third, other
securities requested to be included in such registration.

         4.4 Selection of Underwriters. If any Piggyback Registration is an
underwritten secondary registration on behalf of the holders of the Company's
securities, the selection of investment banker(s) and manager(s) for the
offering must be reasonably acceptable to the holders of a majority of the
Eligible Securities included in such Piggyback Registration. Such approval will
be assumed unless notice to the contrary is given by the holders of a majority
of the Eligible Securities included in such Piggyback Registration to the
Company within ten days of such holders' receipt of notice of selection by the
Company.

         4.5 Other Registrations. If the Company has previously filed a
registration statement with respect to Eligible Securities pursuant to Article 3
or pursuant to this Article 4 and if such previous registration has not been
withdrawn or abandoned, the Company shall not, without the prior written consent
of the holders of a majority of the Eligible Securities included therein, file
or cause to be effected any other registration for

                                       6
<PAGE>   7
the underwritten offering, issue or sale of any of its equity securities or
securities convertible or exchangeable into or exercisable for its equity
securities under the Securities Act (except on Form S-8 or any successor form),
whether on its own behalf or at the request of any holder or holders of such
securities, until a period of at least 120 days has elapsed from the effective
date or earlier withdrawal of such previous registration.

         4.6 Determination Not to Register or to Delay Registration. If at any
time after giving written notice of its intention to register any securities as
to which the Stockholders shall have the rights provided in this Article 4 and
prior to the effective date of the registration statement with respect thereto,
the Company shall determine for any reason not to register or to delay
registration of such securities, the Company may, at its election, give written
notice of such determination to the Stockholders and, thereupon, (i) in the case
of a determination not to register, the Company shall be relieved of its
obligation to register any Eligible Securities in connection with such
registration and (ii) in the case of a determination to delay such registration,
the Company shall be permitted to delay registration of any Eligible Securities
requested to be included in such registration for the same period as the delay
in registering the other securities proposed to be registered by the Company,
but, in either such case, without prejudice to the rights of the holders of
Eligible Securities under Articles 2 and 3. No Stockholder shall have any right
to restrain or otherwise delay registration under Articles 2 through 4.

                                    ARTICLE 5
                               HOLDBACK AGREEMENTS

         5.1 Holdback by Stockholders. Each Stockholder shall not effect any
public sale or distribution (including sales pursuant to Rule 144) of equity
securities of the Company, or any securities convertible into or exchangeable or
exercisable for such securities, during the five business days prior to and, if
required by the underwriter, the 120-day period (or such shorter period as the
underwriters managing the registered public offering may permit) beginning on
the effective date of any underwritten Demand Registration or any underwritten
Piggyback Registration in which Eligible Securities are included (except as part
of such underwritten registration), unless the underwriters managing the
registered public offering otherwise agree.

         5.2 Holdback by Company. In connection with any underwritten
registration, the Company (i) shall not effect any public sale or distribution
of its equity securities, or any securities convertible into or exchangeable or
exercisable for such securities, during the five business days prior to and
during the 120-day period (or such shorter period as the underwriters managing
the registered public offering may permit) beginning on the effective date of
any underwritten Demand Registration or any underwritten Piggyback Registration
(except as part of such underwritten registration or pursuant to registrations
on Form S-8 or any successor form), unless the underwriters managing the
registered public offering otherwise agree, and (ii) shall use its reasonable
best efforts to cause each holder of at least 5% (on a fully-diluted basis) of
its Common Stock, or any securities

                                       7
<PAGE>   8

convertible into or exchangeable or exercisable for Common Stock, purchased from
the Company at any time after the date of this Agreement (other than in a
registered public offering or pursuant to stock options granted under a stock
option plan primarily for employees, officers or directors) to agree not to
effect any public sale or distribution (including sales pursuant to Rule 144) of
any such securities during such period (except as part of such underwritten
registration, if otherwise permitted), unless the underwriters managing the
registered public offering otherwise agree.

                                    ARTICLE 6
                              REGISTRATION EXPENSES

         6.1 Registration Expenses. All Registration Expenses in connection with
any registration pursuant to this Agreement shall be borne by the Company
whether or not it has become effective and whether or not such registration has
counted as the permitted Demand Registrations (unless such registration does not
become effective due solely to the conduct or omission of the Selling
Stockholders requesting such registration). The Company shall, in any event, pay
its internal expenses (including, without limitation, all salaries and expenses
of its officers and employees performing legal or accounting duties), the
expense of any annual audit or quarterly review, the expense of any liability
insurance and the expenses and fees for listing the securities to be registered
on each securities exchange on which similar securities issued by the Company
are then listed or on the NASD automated quotation system.

         6.2 Selling Expenses. The Selling Stockholders shall be responsible for
all Selling Expenses relating to Eligible Securities registered on behalf of the
Selling Stockholders.

         6.3 Fees and Disbursements of Stockholders' Counsel. In connection with
the Resale Registration Statement, the Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Eligible Securities
included in such registration for the reasonable fees and disbursements of one
counsel chosen by the holders of a majority of the Eligible Securities initially
requesting such registration.

         6.4 Allocation of Certain Expenses. To the extent Registration Expenses
are not required to be paid by the Company, each holder of securities included
in any registration hereunder shall pay those Registration Expenses allocable to
the registration of such holder's securities so included, and any Registration
Expenses not so allocable shall be borne by all sellers of securities included
in such registration in proportion to the aggregate selling price of the
securities to be so registered.

                                    ARTICLE 7
                             REGISTRATION PROCEDURES

         7.1 Registration and Qualification. The Company shall, (i) pursuant to
Article 2 and (ii) whenever the Stockholders have requested that any Eligible
Securities be registered pursuant to this Agreement, use its reasonable best
efforts to effect the registration and

                                       8
<PAGE>   9
the sale of such Eligible Securities in accordance with the intended method of
disposition thereof, and pursuant thereto the Company shall as expeditiously as
possible:

        (a) prepare and file with the SEC a registration statement with respect
to such Eligible Securities and use its reasonable best efforts to cause such
registration statement to become effective (provided that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company shall furnish to the counsel selected by the holders of a majority
of the Eligible Securities covered by such registration statement copies of all
such documents proposed to be filed, for review by such counsel for a period of
at least three business days after its receipt thereof) and keep the
registration statement continuously effective under the Securities Act (i) in
the case of the Resale Registration Statement, until the earlier of (x) the
second anniversary of the Closing Date and (y) such date as of which all
Eligible Securities shall cease to be Eligible Securities and (ii) in the case
of the Demand Registration and any Piggyback Registration, for a period of not
less than one year (or such shorter period as may be required until all of the
Eligible Securities so registered have been sold);

        (b) notify each Selling Stockholder of the effectiveness of each
registration statement filed hereunder and 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 for the period described in subparagraph (a) and comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the Selling Stockholders
set forth in such registration statement;

        (c) furnish to each Selling Stockholder such number of copies of such
registration statement, each amendment and supplement thereto, the prospectus
included in such registration statement (including each preliminary prospectus)
and such other documents as such seller may reasonably request in order to
facilitate the disposition of the Eligible Securities owned by Selling
Stockholders;

        (d) use its reasonable best efforts to register or qualify such Eligible
Securities under such other securities or blue sky laws of such jurisdictions as
any Selling Stockholder reasonably requests and do any and all other acts and
things which may be reasonably necessary or advisable to enable such Selling
Stockholder to consummate the disposition in such jurisdictions of the Eligible
Securities owned by such Selling Stockholder; provided, however, that the
Company shall not be required to (i) qualify generally to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
subparagraph, (ii) subject itself to taxation in any such jurisdiction or (iii)
consent to general service of process in any such jurisdiction;

         (e) notify each Selling Stockholder, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such
registration statement contains an

                                       9
<PAGE>   10
untrue statement of a material fact or omits any fact necessary to make the
statements therein not misleading, and, at the request of any such Selling
Stockholder, the Company will prepare a supplement or amendment to such
prospectus so that, as thereafter delivered to the purchasers of such Eligible
Securities, such prospectus will not contain an untrue statement of a material
fact or omit to state any fact necessary to make the statements therein not
misleading;

        (f) as soon as practicable after the Common Stock shall be eligible for
listing on the Nasdaq National Market or, failing that, the Nasdaq SmallCap
Market, use all reasonable efforts to cause all such Eligible Securities to be
listed on the Nasdaq National Market or the Nasdaq SmallCap Market, as the case
may be;

        (g) provide a transfer agent and registrar for all such Eligible
Securities not later than the effective date of such registration statement;

        (h) enter into such customary agreements (including underwriting
agreements in customary form) and take all such other reasonable actions as the
holders of a majority of the Eligible Securities being sold or the underwriters,
if any, reasonably request in order to expedite or facilitate the disposition of
such Eligible Securities;

        (i) otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the SEC;

        (j) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any common stock included in such registration statement for sale in any
jurisdiction, the Company shall use its reasonable best efforts promptly to
obtain the withdrawal of such order; and

        (k) use its reasonable best efforts to cause such Eligible Securities
covered by such registration statement to be registered with or approved by such
other governmental agencies or authorities as may be necessary to enable the
sellers thereof to consummate the disposition of such Eligible Securities.

         7.2 Furnishing Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Agreement with
respect to the Eligible Securities of any Selling Stockholder that such Selling
Stockholder shall furnish to the Company such information regarding itself, the
Eligible Securities held by it and the intended method of disposition of such
securities as shall be required to effect the registration of such Selling
Stockholder's Eligible Securities.

         7.3 Underwriting. In the event that any registration pursuant to this
Agreement shall involve, in whole or in part, an underwritten offering, the
Company may require Eligible Securities to be included in such underwriting on
the same terms and conditions as shall be applicable to the Common Stock being
sold through underwriters under such

                                       10
<PAGE>   11
registration. In such case, the holders of Eligible Securities on whose behalf
Eligible Securities are to be distributed by such underwriters shall be parties
to any such underwriting agreement.

                                    ARTICLE 8
                                 INDEMNIFICATION

         8.1 Indemnification by the Company. In the event of any registration of
any Eligible Securities hereunder, the Company hereby agrees to indemnify and
hold harmless each Stockholder and, to the extent applicable, its directors and
officers, its partners, its trustees and each Person who controls any of such
Persons, to the extent permitted by law, against any losses, claims, damages,
liabilities and expenses, joint or several, to which such Person may be subject
under the Securities Act or otherwise insofar as such losses, claims, damages,
liabilities or expenses (or actions or proceedings in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any final prospectus
included therein, or any amendment or supplement thereto, or any document
incorporated by reference therein, or (ii) any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and the Company will promptly reimburse
each such Person for any legal or any other expenses reasonably incurred by such
Person in connection with investigating or defending any such loss, claim,
damage, liability, action or proceeding; provided that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such registration statement, any final prospectus,
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Selling Stockholders expressly for
use in the registration statement. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of a Selling
Stockholder or any such Person and shall survive the transfer of such securities
by the Selling Stockholders.

         8.2 Indemnification by Selling Stockholders. The Selling Stockholders
agree severally and not jointly to indemnify and hold harmless, to the extent
permitted by law, (in the same manner and to the same extent as set forth in
Paragraph 8.1 of this Article 8) the Company, each director of the Company, each
officer of the Company who shall sign such registration statement, and each
Person, if any, who controls the Company within the meaning of the Securities
Act, with respect to (i) any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any final prospectus
included therein, or any amendment or supplement thereto, or any document
incorporated by reference therein, or (ii) any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and the Selling Stockholders will
promptly reimburse each such Person for any legal or

                                       11
<PAGE>   12

any other expenses reasonably incurred by such Person in connection with
investigating or defending any such loss, claim, damage, liability, action or
proceeding, but only to the extent that such statement or omission was made in
reliance upon and in conformity with written information furnished by such
Selling Stockholders to the Company expressly for use in the registration
statement; provided that the obligation to indemnify and the contribution
obligation set forth in Article 9 hereof will be limited to the gross proceeds
received by such holder from the sale of Eligible Securities. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of the Company or any such director, officer or controlling Person and
shall survive the transfer of the registered securities by the Selling
Stockholders and the expiration of this Agreement.

         8.3 Qualification. Indemnification similar to that specified in the
preceding subdivisions of this Article 8 (with appropriate modifications) shall
be given by the Company and the Selling Stockholders with respect to any
required registration or other qualification of such Eligible Securities under
any federal or state law or regulation of governmental authority other than the
Securities Act.

                                    ARTICLE 9
                                  CONTRIBUTION

         Subject to the limitation on indemnification and contribution set forth
in Section 8.2 of Article 8, if the indemnification provided for in Article 8
hereof is unavailable to a party entitled to indemnification in respect of any
losses, claims, damages, liabilities or expenses referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses in such proportion as
is appropriate to reflect the relative fault of the Company on the one hand and
of the Selling Stockholders on the other in connection with the statements or
omissions that resulted in such losses, claims, damages, liabilities or expenses
as well as any other relevant equitable considerations. The relative fault of
the Company on the one hand and of the Selling Stockholders on the other 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, or by the
Selling Stockholders, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The indemnity and contribution obligations of each indemnifying party set forth
herein shall be in addition to any liability or obligation such indemnifying
party may otherwise have to any indemnified party, including under this
Agreement.

                                   ARTICLE 10
                                  MISCELLANEOUS

register Eligible Securities granted to Selling Stockholders hereunder may be

case may be, in connection with any transfer or assignment in a private
transaction of Eligible Securities. Any transfer of registration rights pursuant
to this Section shall be effective upon receipt by the Company of written notice
from a Selling Stockholder transferring Eligible Securities (i) stating the name
and address of the transferee, (ii) the number of Eligible Securities
transferred and (iii) the date of transfer, which notice shall be accompanied by
an agreement of the transferee stating that all of the terms and provisions of
this Agreement will be binding upon and enforceable against such transferee.

THE SECURITY EVIDENCED BY THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED OR
ASSIGNED, EXCEPT AS EXPLICITLY PROVIDED HEREIN.

       Agreement and Warrant to Purchase<<Number_of_Shares>>Common Shares
                                Spatialight, Inc.
                               (December __, 1999)

This Agreement and Non-Transferrable Warrant (the "Warrant") certifies that, for
value received, <<Name>>, the registered holder hereof (the "Warrantholder") is
entitled to purchase from Spatialight, Inc., a New York corporation with its
principal office at 9 Commercial Boulevard, Suite 200, Novato, California 94949
(the "Company") <<Number_of_Shares>> shares of Common Stock of the Company (the
"Shares") at or before 5:00 p.m. Eastern Standard Time on June 30, 2002, at the
purchase price per share of $3.50 (the "Warrant Price"), subject to the
following terms and conditions. The number of Shares purchasable upon exercise
of this Warrant and the Warrant Price per Share shall be subject to adjustment
from time to time as set forth herein.

1.      Consideration for Warrant.

        This Warrant has been issued in consideration of a loan provided to the
        Company by Warrantholder, the receipt of which is hereby acknowledged.

2.      Exercise.

        (a) This Warrant may be exercised in whole or in part by presentation of
        this Warrant with the Purchase Form as attached hereto duly completed
        and executed, together with payment of the Warrant Price at the
        principal office of the Company. Payment of the Warrant Price may be
        made in cash, by wire transfer, by check or pursuant to the provisions
        of Section 2(b) below. Upon surrender of the Warrant and payment of such
        Warrant Price as aforesaid, the Company shall issue and cause to be
        delivered with all reasonable dispatch to or upon the written order of
        the Warrantholder and in such name or names as the Warrantholder may
        designate a certificate or certificates for the number of full Shares so
        purchased upon the exercise of the Warrant, together with Fractional
        Warrants, as provided in Section 7 hereof, in respect of any fractional
        Shares otherwise issuable upon such surrender. Such certificate or
        certificates shall be deemed to have been issued and any person so
        designated to be named therein shall be deemed to have become a holder
        of record of such Shares as of the date of the surrender of the Warrant
        and the payment of the Warrant Price, as aforesaid, notwithstanding that
        the certificates representing the Shares shall not actually have been
        delivered or that the stock transfer books of the Company shall then be
        closed. In the event that the Warrant is exercised in respect of less
        than all of the Shares specified herein at any time prior to the
        Termination Date, a new Warrant evidencing the remaining Shares will be
        issued by the Company.

                                       1
<PAGE>   2

        The Company shall pay any and all transfer taxes or similar charges
        which may become due upon exercise of the Warrant.

        (b) Notwithstanding any provisions herein to the contrary, so long as
        and to the extent that this Warrant may be exercised, in lieu of
        exercising the Warrant for cash, the holder may elect to receive shares
        of Common Stock equal to the value (as determined below) of this Warrant
        (or the portion thereof being exercised). The holder may make the
        election described in this Section 2(b) by surrendering this Warrant,
        delivering a notice of election under this provision and providing the
        other documents referenced in Section 2(a), following the procedures set
        forth in such section. In such event the Company shall issue (i) within
        thirty (30) days a new Warrant substantially in the form hereof
        representing the number of Shares with respect to which this Warrant
        shall not then have been exercised and (ii) a number of Shares computed
        using the following formula:

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

Where    X =     the number of Shares to be issued,
         Y =     the portion of the Warrant being exercised,
         A =     the fair market value of one share of Common Stock (at the
                 date of such calculation), and
         B =     the Warrant Price.

               For purposes of the above calculation, fair market value of one
        share of Common Stock shall be determined by the Board in good faith;
        provided, however, that where there exists a public market for the
        Company's Common Stock at the time of such exercise, fair market value
        shall mean the average over the preceding ten trading days (or such
        fewer number of days as such public market has existed) of the average
        of the high and low prices on the over-the-counter market as reported by
        the National Association of Securities Dealers Automated Quotation
        ("Nasdaq") system, or if the Common Stock of the Company is then traded
        on a national securities exchange or the Nasdaq Stock Market, the
        average over the preceding ten (10) trading days (or such fewer number
        of days as the Common Stock has been so traded) of the closing sale
        prices on the principal national securities exchange or the Nasdaq
        market on which it is so traded.

3.      Reservation of Shares.

        On or after the date of this Warrant, the Company will reserve from its
        authorized and unissued shares of Common Stock a sufficient number of
        shares to provide for the issuance of Shares upon the exercise of this
        Warrant. Every transfer agent for the securities of the company issuable
        upon the exercise of the Warrant will be irrevocably authorized and
        directed at all times to reserve such number of authorized Shares and
        other securities as shall be requisite for such purpose. The Company
        will keep a copy of this Warrant on file with every transfer agent for
        the securities of the Company issuable upon the exercise of the Warrant.
        The Company will supply such transfer agent with duly executed stock and
        other certificates for such purpose.

4.      Further Obligations of Company.

        4.1.   The Company covenants and agrees that all Shares which may be
               delivered upon exercise of this Warrant shall, upon delivery, be
               fully paid and non-assessable, and be free from all taxes, liens
               and charges with respect to the purchase thereof hereunder, and
               without limiting the generality of the foregoing, the Company
               covenants and agrees that it shall from time to time take all
               such actions as may be necessary to assure that the par value per
               share of the Common Stock is at all times equal to or less than
               the then current Warrant Price per share of the Shares issuable
               pursuant to this Warrant.

        4.2.   If the Warrantholder claims that this Warrant has been mutilated,
               lost, destroyed or wrongfully taken, the Company shall issue and
               deliver to the Warrantholder a replacement Warrant provided that
               the requirements of Section 8-405 of the New York Uniform
               Commercial Code has been met and, if this Warrant has been
               mutilated, that it is surrendered to the Company.

5.      Registration.

        The Warrant shall be registered on the books of the Company when issued
        and shall be transferable only on the books of the Company maintained at
        its principal office in Novato, California, or wherever its principal
        executive offices may then be located, upon delivery thereof duly
        endorsed by the Warrantholder or its duly authorized attorney or
        representative, or accompanied by proper evidence of succession,
        assignment or authority to transfer. This Warrant shall not be
        transferable in whole or in part unless the Company pre-approves such
        transfer in writing, provided, however, that the Company shall
        pre-approve reasonable transfers made for estate planning purposes. Upon
        any registration or approved transfer, the Company shall execute and
        deliver a new Warrant or Warrants to the person or persons entitled
        thereto.

6.      Adjustment of Warrant Price and Number of Shares.

        6.1.   General. The number of Shares purchasable upon the exercise of
               the Warrant and the Warrant Price shall be subject to adjustment
               from time to time upon the happening of certain events, as
               follows:

               6.1.1. In case the Company shall, with regard to its Common Stock
                      (or securities convertible into or exchangeable for Common
                      Stock) (A) pay a dividend in Common Stock or make a
                      distribution in Common Stock, (B) subdivide its
                      outstanding shares of Common Stock into a greater number
                      of shares, (C) combine its outstanding shares of Common
                      Stock into a smaller number of shares, or (D) issue by
                      reclassification of its Common Stock or other securities
                      of the Company, the number of Shares purchasable upon
                      exercise of the Warrant immediately prior thereto shall be
                      adjusted so that the Warrantholder shall be entitled to
                      receive the kind and number of Shares or other securities
                      of the Company which it would have owned or would have
                      been entitled to receive after the happening of any of the
                      events described above, had the Warrant been exercised
                      immediately prior to the happening of such event or any
                      record date with respect thereto. Any adjustment made
                      pursuant to this subsection shall become effective
                      immediately after the effective date of such event
                      retroactive to the record date, if any, for such event.

               6.1.2. No adjustment in the number of Shares purchasable
                      hereunder shall be required unless such adjustment would
                      require an increase or decrease of at least one percent in
                      the aggregate number of Shares then purchasable upon the
                      exercise of the Warrant; provided however, that any
                      adjustments which by reason of this Section 6.1.2 are not
                      required to be made immediately shall be carried forward
                      and taken into account in any subsequent adjustment.

               6.1.3. Whenever the number of Shares purchasable upon the
                      exercise of the Warrant is adjusted as herein provided,
                      the Warrant Price payable upon exercise of the Warrant
                      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
                      purchasable upon the exercise of the Warrant immediately
                      prior to such adjustment, and of which the denominator
                      shall be the number of shares so purchasable immediately
                      thereafter.

               6.1.4. Whenever the number of Shares purchasable upon the
                      exercise of this Warrant or the Warrant Price is adjusted
                      as herein provided, the Company shall cause to be promptly
                      mailed to the Warrantholder in accordance with the
                      provisions of Section 9 hereof, notice of such adjustment
                      or adjustments and a certificate of a firm of independent
                      public accountants

<PAGE>   5

                      selected by the Board of Directors of the Company (who may
                      be the regular accountants employed by the Company)
                      setting forth the number of Shares purchasable upon the
                      exercise of the Warrant and the Warrant Price after such
                      adjustment, a brief statement of the facts requiring such
                      adjustment, and the computation by which such adjustment
                      was made.

               6.1.5. For the purpose of this Section 6.1, the term "Common
                      Stock" shall mean (A) the class of shares designated as
                      the Common Stock of the Company at the date of this
                      Warrant, or (B) any other class of shares resulting from
                      successive changes or reclassifications of such Common
                      Stock including changes in a par value, or from par value
                      to no par value, or from no par value to par value. In the
                      event that at any time, as a result of an adjustment made
                      pursuant to this Section 6, the Warrantholder shall become
                      entitled to purchase any shares of the Company other than
                      shares of Common Stock, thereafter the number of such
                      other shares so purchasable upon exercise of the Warrant
                      and the Warrant Price of such shares shall be subject to
                      adjustment from time to time in a manner and on terms as
                      nearly equivalent as practicable to the provisions with
                      respect to the Shares contained in this Section 6.

        6.2.   No Adjustment of Dividends. Except as provided in Section 6.1, no
               adjustment in respect of dividends shall be made during the term
               of the Warrant or upon the exercise of the Warrant.

        6.3.   Preservation of Purchase Rights upon Reorganization,
               Reclassification, Consolidation, Merger, etc. In case of any
               capital reorganization or reclassification of the Common Stock of
               the Company, or in case of any consolidation of the Company with
               or merger of the Company into another corporation or in case of
               any sale or conveyance to another person of the property, assets
               or business of the Company as an entirety or substantially as an
               entirety, the Company or such successor or purchaser, as the case
               may be, shall execute with the Warrantholder an agreement that
               the Warrantholder shall have the right thereafter upon payment of
               the Warrant Price in effect immediately prior to such action to
               purchase upon exercise of the Warrant 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 reorganization or reclassification, consolidation, merger,
               sale or conveyance had the Warrant been exercised immediately
               prior to such action. In the event of a merger described in
               Section 368(a)(2)(E) of the Internal Revenue Code of 1986, as
               amended, in which the Company is the surviving corporation, the
               right to purchase Shares under the Warrant shall terminate on the
               date of such merger and thereupon the Warrant shall become null
               and void but only if the controlling corporation shall agree to
               substitute for the Warrant its warrant which entitles the holder
               thereof to purchase upon its exercise the kind and amount of
               shares and other securities and property which it would have
               owned or had been entitled to receive has the Warrant been

                                       5

               exercised immediately prior to such merger. The adjustments
               required by this Section 6.3 shall be effected in a manner which
               shall be as nearly equivalent as may be practicable to the
               adjustments provided for elsewhere in this Section 6. The
               provisions of this Section 6.3 shall similarly apply to
               successive consolidations, mergers, sales or conveyances.

        6.4.   Statement on Warrants; Legends. Irrespective of any adjustments
               in the Warrant Price or the number or kind of Shares purchasable
               upon the exercise of the Warrant, the Warrant certificate or
               certificates theretofore or thereafter issued may continue to
               express the same price and number and kind of Shares as are
               stated in this initially issued Warrant. The Company may at any
               time place legends referencing any applicable securities law
               restrictions on certificates representing the Shares. Holder
               shall, at the request of the Company, promptly present to the
               Company any and all certificates representing the Shares in order
               to carry out the provisions of this Section.

7.      Fractional Shares.

        The Company shall not be required to issue fractional Shares on the
        exercise of the Warrant. If any fraction of a Share would, except for
        the provisions of this Section 7, be issuable on the exercise of the
        Warrant (or specified portion thereof), the Company shall issue to the
        Warrantholder a fractional Warrant entitling Warrantholder, upon
        surrender with other fractional Warrants aggregating one or more full
        Shares, to purchase such full Shares. If fractional Warrants do not
        aggregate a full Share, their value (over and above their exercise
        price) shall be paid in full in cash upon exercise to the exercising
        Warrantholder.

8.      No Rights as Shareholder; Notices to Warrantholder.

        Nothing contained in this Warrant shall be construed as conferring upon
        the Warrantholder or its transferees any rights as shareholder of the
        Company, including the right to vote, receive dividends, or consent as a
        shareholder in respect of any meeting of shareholders for the election
        of directors of the Company or any other matter. However, the Company
        shall be required to give notice in writing to the Warrantholder of any
        meeting of shareholders of the Company or any proposed consent of the
        shareholders as provided in Section 9 hereof at least twenty (20) days
        prior to the date fixed as a record date or the date of closing the
        transfer books for the determination of the shareholders entitled to any
        relevant dividend, distribution, subscription rights or other rights or
        for the determination of shareholders entitled to vote at any such
        meeting or as to which any consent is requested. Such notice shall
        specify such record date or the date of closing the transfer books, as
        the case may be.

        State of New York, and for all purposes shall be construed in accordance

        performed entirely within such State, without regard to principles of
        conflicts of law.

                       INVESTMENT REPRESENTATION STATEMENT

Shares of the Common Stock of
Spatialight, Inc.

In connection with the purchase of the above-listed securities, the undersigned
hereby represents to Spatialight, Inc. (the "Company") as follows

(a) The shares of Common Stock and other securities, if any, to be received upon
the exercise of the Warrant (the "Securities") will be acquired for investment
for its own account, not as a nominee or agent, and not with a view to the sale
or distribution of any part thereof, and the undersigned has no present
intention of selling, granting participation in or otherwise distributing the
same, but subject, nevertheless, to any requirement of law that the disposition
of its property shall at all times be within its control. By executing this
Statement, the undersigned further represents that it does not have any
contract, undertaking, agreement or arrangement with any person to sell,
transfer, or grant participations to such person or to any third person, with
respect to any Securities issuable upon exercise of this warrant.

(b) The undersigned understands that the Securities issuable upon exercise of
the Warrant at the time of issuance may not be registered under the Securities
Act of 1933, as amended (the "Act"), and applicable state securities laws, on
the ground that the issuance of such securities is exempt pursuant to Section
4(2) of the Act and state law exemptions relating to offers and sales not by
means of a public offering, and that the Company's reliance on such exemptions
is predicated on the undersigned's representations set forth herein.

(c) The undersigned agrees that in no event will it make a disposition of any
Securities acquired upon the exercise of the Warrant unless and until it shall
have furnished the Company with an opinion of counsel satisfactory to the
Company and Company's counsel to the effect that (A) appropriate action
necessary for compliance with the Act and any applicable state securities laws
has been taken or an exemption from the registration requirements of the Act and
such laws is available, and (B) that the proposed transfer will not violate any
of said laws

(d) The undersigned acknowledges that an investment in the Company is highly
speculative and represents that it is able to fend for itself in the
transactions contemplated by this Statement, has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of its investments, and has the ability to bear the economic risks
(including the risk of a total loss) of its investment. The undersigned
represents that it has had the opportunity to ask questions of the Company
concerning the Company's business and assets and to obtain any additional
information which it considered necessary to verify the accuracy of or to
amplify the Company's disclosures, and has had all questions which have been
asked by it satisfactorily answered by the Company.

                                       11
<PAGE>   12

(e) The undersigned acknowledges that the Securities issuable upon exercise of
the Warrant must be held indefinitely unless subsequently registered under the
Act or an exemption from such registration is available. The undersigned is
aware of the provisions of Rule 144 promulgated under the Act which permit
limited resale of shares purchased in a private placement subject to the
satisfaction of certain conditions, including, among other things, the existence
of a public market for the shares, the availability of certain current public
information about the Company, the resale occurring not less than one year after
a party has purchased and paid for the security to be sold, the sale being
through a "broker's transaction" or in transactions directly with "market
makers" (as provided by Rule 144(f)) and the number of shares being sold during
any three-month period not exceeding specified limitations.
