respect to the voting, sale, transfer or registration of any shares of Common
Stock of the Company. No outstanding options, warrants or other securities

voting, sale, transfer or registration of any shares of capital stock of any
Subsidiary.

         4.4 Partnerships and LLCs. The Company is not a party to, and does not

contemplated hereby and thereby and the issuance and sale of the Notes and the
Non-transferable Warrants have been duly authorized by all necessary corporate
action on the part of the Company. Each Loan Document has been duly and validly
executed and delivered by the Company and constitutes the legal, valid and
binding obligation of the Company, enforceable against it in accordance with its
terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and similar laws affecting creditors' rights and
remedies generally, and subject, as to enforceability, to general principles of
equity, including principles of commercial reasonableness, good faith and fair

against the Company or any of its Subsidiaries, or any properties or rights of
the Company or its Subsidiaries, before any court, arbitrator or administrative,
governmental or regulatory authority or body, domestic or foreign, that could
reasonably be expected to have a Material Adverse Effect. The Company has no

in violation of, and to the Company's knowledge, are in compliance with all
material requirements and provisions of such insurance. The Company and its
Subsidiaries have not been refused any insurance coverage sought or applied for,
and the Company has no reason to believe that it will be unable to renew its
existing insurance coverage upon terms at least as favorable as those presently
in effect, other than possible increases in premiums that do not result from any
act or omission of the Company or its Subsidiaries.

         4.9 Patents and Trademarks. The Company and its Subsidiaries have

or any of its Subsidiaries bound by or a party to any options, licenses or
agreements of any kind with respect to the patents, trademarks, service marks,
trade names, copyrights, trade secrets, proprietary rights or processes of any
other Person. A list of all patents, trademarks, service marks, trade names and
copyrights owned by the Company or any of its Subsidiaries is set forth on
Schedule 4.9(a). Except as set forth on Schedule 4.9(b), since January 1, 1998,

the Company or any of its Subsidiaries has violated or, by conducting its
business as proposed, would violate any of the patents (including pending patent
applications), trademarks, service marks, trade names, copyrights, trade
secrets, proprietary rights or processes of any other Person, nor is the Company
aware of any such violations. The Company is not aware of any infringements or
threatened infringements of the Intellectual Property.

its Subsidiaries (including, without limitation, any law, rule or regulation
relating to protection of the environment and the maintenance of safe and
sanitary premises). The execution, delivery and performance of each Loan
Document and the consummation of the transactions contemplated hereby and
thereby will not result in any such violation or be in conflict with or
constitute, with or without the passage of time and giving of notice, either a
default under any such provision, instrument, judgment,



                                       9
<PAGE>   10
order, writ, decree, contract or agreement, or require any consent, waiver or
approval thereunder, or constitute an event that results in the creation of any
Lien upon any assets of the Company or any of its Subsidiaries except as created
by the Loan Documents.

                  (b) The Company and its Subsidiaries have all Permits of all
governmental entities required to conduct their respective businesses as
proposed to be conducted, except to the extent that the failure to have such
Permits would not, and reasonably could not be expected to, have a Material
Adverse Effect.

         4.11 Material Agreements; Action. Except as set forth on Schedule 4.11,
there are no material contracts, agreements, commitments, understandings or
proposed transactions to which the Company or any of its Subsidiaries is a party
or by which it is bound regarding: (i) any of their respective officers,
directors, stockholders or partners; (ii) the sale of any of the assets of the
Company or any of its Subsidiaries other than in the ordinary course of
business; (iii) covenants of the Company or any of its Subsidiaries not to
compete in any line of business or with any Person in any geographical area or

the license or grant of any interest in any of the Intellectual Property or
other material proprietary right to or from the Company or any of its
Subsidiaries, except as created by the Loan Documents. To the Company's
knowledge, all such agreements are in full force and effect and are the legal,
valid and binding obligation of the Company or its Subsidiaries, enforceable
against them in accordance with their terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium and similar laws affecting creditors'
rights and remedies generally and subject, as to enforceability, to general
principles of equity (regardless of whether enforcement is sought in a
proceeding at law or in equity).

        4.12 Disclosure. To the best of the Company's knowledge, neither this
Agreement nor any of the Loan Documents nor any exhibit hereto, nor any
certificate, or instrument furnished to Lender or its counsel in connection with
the transactions contemplated by this Agreement, when read together, contains or
will contain any untrue statement of a material fact or omits or will omit to
state a material fact necessary in order to make the statements contained herein

the use of trade secrets or proprietary information of others, and the
employment of the employees of the Company or any Subsidiary does not subject
the Company or any Subsidiary to any liability arising by reason of any such

material respects with all laws relating to employment or labor, including

                                    SECTION 5

             Representations, Warranties and Covenants of the Lender

         Each Lender severally hereby represents and warrants to and agrees with
the Company, as to itself only, as follows:

         5.1 Accredited Investor; Investment. Lender is an accredited investor
within the definition of Regulation D promulgated under the Securities Act.
Lender has such



                                       14
<PAGE>   15
knowledge and experience in financial and business matters that it is capable of
evaluating the merits and risks of the transactions contemplated herein. Lender
is acquiring its respective Note for investment purposes only, for its own
account and not with a view to, or for resale in connection with, any
distribution thereof in violation of applicable law.

        5.2 Risk. Lender acknowledges that it, he or she is aware that the
Company is currently insolvent and has not had any revenues and has sustained
losses for the past several years. The Lender further acknowledges that (x)
there can be no assurance that the Company will have sufficient funds to repay
all or any portion of the loan being borrowed hereunder, (y) that the collateral
securing the loan will have sufficient value to repay the loan or (z) that the
securities into which the loan may be converted will have any value. Lender
further confirms that the Company has made available to the Lender the
opportunity to ask questions of and receive answers from the Company concerning
the Company and the activities of the Company.

         5.3 Authorization. Lender represents that it has all requisite power
and authority to enter into and perform its obligations under the Loan Documents
to which it is a party. Assuming the due authorization, execution and delivery
of the Loan Documents by each other party thereto, each Loan Document to which
Lender is a party constitutes a valid and binding obligation of Lender,
enforceable against it in accordance with its terms, subject to applicable
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
similar laws affecting creditors' rights and remedies generally, and subject, as
to enforceability, to general principles of equity, including principles of
commercial reasonableness, good faith and fair dealing (regardless of whether
enforcement is sought in a proceeding at law or in equity) and except to the
extent that rights to indemnification and contribution under this Agreement may
be limited by federal or state securities laws or public policy relating
thereto.

         5.4 Consents. No consent, approval, order or authorization of, or
registration, qualification, designation, declaration or filing with, any
federal, state, or local governmental authority or other Person on the part of
Lender is required in connection with the valid execution and delivery by Lender
of the Loan Documents to which it is a party, or the consummation by Lender of
the transactions contemplated by the Loan Documents to which it is a party,
except for such filings as have been made prior to the Closing. Lenders are
residents of the states listed on Schedule 5.4.

         5.5 Brokers' Fees. No broker, finder, investment banker or other Person
is entitled to any brokerage fee, finder's fee or other commission in connection
with the transactions contemplated by this Agreement and based upon arrangements
made by Lender.

         5.6 Restrictive Legends. Lender understands that the common shares to
be issued upon conversion of the Note (the "Conversion Shares"), shall bear a
restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer



                                       15
<PAGE>   16
of such stock certificates) until such time as the sale of the Conversion Shares
have been registered under the Securities Act as contemplated hereunder:

         THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT",) OR ANY STATE
         OR FOREIGN SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD OR TRANSFERRED
         EXCEPT IN COMPLIANCE THEREWITH.

If Lender desires to sell or otherwise dispose of all or any part of such common
shares under an exemption from registration under the Securities Act, and if
requested by the Company, such Lender shall deliver to the Company an opinion of
counsel, which may be counsel for the Company, that such exemption is available.

        5.7 Receipt of Information. Lender has reviewed all periodic reports,
statements and other documents that the Company and its principal shareholders
have filed with the Securities and Exchange Commission (the "SEC") under the
Exchange Act since January 1, 1998, which filings are incorporated by reference
into the information provided by the Company to Lender.

                                    SECTION 6

                            Covenants of the Company

         6.1 Information. After the Closing Date and until the later to occur of
the date (the "Cessation Date") on which the Notes are fully repaid or converted
into equity of the Company, the Company will send each Lender the information
specified in this Section 6.1:

                  (a) Shareholders Information. Any and all materials which the
Company sends to the holders of its Common Shares shall be sent to each Lender
on the same date on which it is sent to such shareholders.

                  (b) Quarterly Financial Statements. As soon as available, but
in any event no later than forty-five (45) days after the end of each fiscal
quarter (other than the fourth fiscal quarter of the Company), the unaudited
consolidated balance sheet of the Company and its Subsidiaries as at the end of
each such quarter and the related unaudited consolidated statements of income
and cash flows of the Company and its Subsidiaries for such quarter and for the
elapsed period in such fiscal year, all in reasonable detail and stating in
comparative form the figures as of the end of and for the comparable periods of
the preceding fiscal year. All such financial statements shall be prepared in
accordance with GAAP on a consistent basis throughout the periods reflected
therein except as stated therein and shall be accompanied by a certificate of
the Company's president or chief financial officer to such effect.



                                       16
<PAGE>   17
                  (c) Other Reports and Statements. Promptly (but in any event
within ten (10) days after any distribution to its stockholders generally, to
its directors or to the financial community of an annual report, definitive
proxy statement, registration statement or other similar report or
communication, and promptly (but in any event within ten (10) days) after any
filing by the Company with the SEC or with any national securities exchange or
market system, of any publicly available annual or periodic or special report or
proxy statement or registration statement, a copy of such report or statement
and copies of all press releases and other statements made available generally
by the Company to the public concerning material developments in the Company's
business, shall be sent to each Lender.

         6.2 Preemptive Rights. If at any time after the Closing Date and prior
to the Cessation Date, the Company shall propose to issue or sell New Securities
or enters into any contracts, commitments, agreements, understandings or
arrangements of any kind relating to the issuance or sale of any New Securities,
then each Lender shall have the right to purchase that number of New Securities
at the same price and on the same terms proposed to be issued or sold by the
Company so that such Lender would after the issuance and sale of all such New
Securities, hold the same proportional interest of the then outstanding shares
of Common Stock (assuming that any outstanding securities or other rights,
including the Notes, convertible or exchangeable into Common Stock have been
converted or exchanged) as was held by such Lender immediately prior to such
issuance and sale (the "Proportionate Percentage").

        The Company shall give each Lender written notice of its intention to
issue and sell New Securities, describing the type of New Securities, the price
and the general terms and conditions upon which the Company proposes to issue
the same. Each Lender shall have ten (10) Business Days from the giving of such
notice to agree to purchase all (or any part) of its Proportionate Percentage of
New Securities for the price and upon the terms and conditions specified in the
notice by giving written notice to the Company and stating therein the quantity
of New Securities to be purchased.

         If Lenders fail to exercise in full such right within ten (10) Business
Days, the Company shall have one hundred twenty-five (125) days thereafter to
sell the New Securities in respect of which Lenders' rights were not exercised,
at a price and upon general terms and conditions no more favorable to the buyers
thereof than specified in the Company's notice to Lenders pursuant to this
Section. If the Company has not sold the New Securities within such one hundred
twenty-five (125) day period, the Company shall not thereafter issue or sell any
New Securities, except by giving Lenders the right to purchase their
Proportionate Percentage in the manner provided above.

         6.3 Negative Covenants. (a) Prior to the date on which the Notes are
paid in full, the Company shall not, without the prior written consent of each
Lender:

interest which is senior to, or pari passu with, the Note;

                  (ii) Declare or pay any dividend on its Common Stock;

                  (iii) Redeem for cash any securities issued by the Company;

                  (iv) Directly or indirectly, consummate any merger,

and a merger of Spatialight of California, Inc. with and into the Company), or
the sale, lease or other transfer of all or substantially all of its assets;

                  (v) Issue any options, warrants, or other securities to any
officer or director of the Company, except for an issuance under the 1991 Stock
Option Plan, the 1993 Employee Stock Option Plan, as amended, the 1993 Directors
Stock Option Plan, and the 1999 Stock Option Plan; or

                  (vi) Incur any indebtedness in excess of currently outstanding
debt, the $2,875,000 loan contemplated hereby and $2,125,000 in financing on
terms substantially similar to the loan contemplated hereby, without the prior
written consent of the Lenders representing more than 75% of the outstanding
debt.

                  (b) Prior to the Cessation Date, the Company shall not,
without the prior written consent of each Lender:

                  (i) issue any security which is preferred in dividends or in
liquidation to the Common Stock, which is not convertible into Common Stock; or

                  (ii) issue any preferred stock, convertible debenture or other
security which is preferred in dividends to the Common Stock, which is intended
to, or can reasonably be expected to pay the purchaser of such security an
annual preferred yield of greater than ten percent per annum, on the issue price
of such security.

         6.4 Loss, Theft or Destruction of Notes. Upon receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of any Note and, in the case of any such loss, theft or destruction,
upon receipt of indemnity reasonably satisfactory to the Company, or in the case
of any such mutilation, upon surrender and cancellation of any Note, the Company
will make and deliver, in lieu of such lost, stolen, destroyed or mutilated
Note, a new Note of like tenor and unpaid principal amount and dated as of the
date to which interest has been paid on the unpaid principal amount of the Note
so lost, stolen, destroyed or mutilated, or, if no interest shall have been paid
thereon, then dated as of the date of the Note so lost, stolen, destroyed or
mutilated.

                                    SECTION 7

                                 Indemnification

         7.1 Indemnification by Company. The Company agrees to indemnify and
hold harmless each Lender and its respective partners, co-investors, officers,
directors, employees, agents, consultants, attorneys and advisers (each, a
"Lender Indemnified Party"), from and against any and all actual losses, claims,
damages, liabilities, costs and expenses (including, without limitation,
environmental liabilities, costs and expenses and all reasonable fees, expenses
and disbursements of counsel), joint or several (hereinafter collectively
referred to as a "Loss" or "Losses"), which may be incurred by or asserted or
awarded against any Lender Indemnified Party in connection with or in any manner
arising out of or relating to any investigation, litigation or proceeding or the
preparation of any defense with respect thereto, arising out of or in connection
with or relating to this Agreement, the other Loan Documents or the transactions
contemplated hereby or thereby, any breach of any representation, warranty or
covenant made by the Company in this Agreement, any use made or proposed to be
made with the proceeds of Lender's respective Note pursuant to this Agreement,
whether or not such investigation, litigation or proceeding is brought by the
Company, any of its Subsidiaries, shareholders or creditors, but excluding
therefrom any Losses arising out of resulting from (i) the gross negligence or
willful misconduct of an Lender Indemnified Party, (ii) any violation by an
Lender Indemnified Party of any law, governmental regulation or court order
applicable to it or (iii) the breach by an Lender Indemnified Party of any
provision of this Agreement or any of the other Loan Documents.

         7.2 Indemnification by Lender. Each Lender severally agrees to
indemnify and hold harmless the Company and its respective officers, directors,
employees, agents, consultants, attorneys and advisers (each, a "Company
Indemnified Party"), from and against any and all Losses, which may be incurred
by or asserted or awarded against any Company Indemnified Party in connection
with or in any manner arising out of or relating to any investigation,
litigation or proceeding or the preparation of any defense with respect thereto,
arising out of or in connection with or relating to any breach of any
representation, warranty or covenant made by such Lender in this Agreement.
Notwithstanding the foregoing, no Lender shall be liable under this Section 7.2
for an amount in excess of that Lender's principal as set forth on Exhibit A.

         7.3 Notice of Claim. An indemnified party shall give written notice to
the indemnifying party of any claim with respect to which it seeks
indemnification within ten (10) days after the discovery by such parties of any
matters giving arise to a claim for indemnification pursuant to this Section 7,
provided that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligations under this
Section 7, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice. In case any such action or claim is
brought against any indemnified party, the indemnifying party shall be entitled
to



                                       19
<PAGE>   20
participate in and, unless in the reasonable good faith judgment of the
indemnified party a conflict of interest between such indemnified party and the
indemnifying party may exist in respect of such action or claim, to assume that
defense thereof, with counsel satisfactory to the indemnified party and after
notice from the indemnifying party to the indemnified party of its election so
to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently incurred by
the latter in connection with the defense thereof other than reasonable costs of
investigation. In any event, unless and until the indemnifying party elects in
writing to assume and does so assume the defense of any such action or claim the
indemnified party's costs and expenses arising out of the defense, settlement or
compromise of any such action or claim shall be Losses subject to
indemnification hereunder. If the indemnifying party elects to defend any such
action or claim, then the indemnified party shall be entitled to participate in
such defense with counsel of its choice at its sole cost and expense. The
indemnifying party shall not be liable for any settlement of any action or claim
effected without its written consent. Anything in this Section 7 to the contrary
notwithstanding, the indemnifying party shall not, without the indemnified
party's prior written consent, settle or compromise any claim or consent to
entry of any judgment in respect thereof that imposes any future obligation on
the indemnified party or that does not include, as an unconditional term
thereof, the giving by the claimant or the plaintiff to the indemnified party, a
release from all liability in respect of such claim.

                                    SECTION 8

may be amended, modified, supplemented or waived, except by a written instrument
executed by (i) the Company and (ii) Lenders representing more than half of the
outstanding debt, provided however, that no amendment, modification, supplement
or waiver adverse to a Lender will be binding upon a Lender that has not agreed
to such provision.

         8.3 Survival of Representations and Warranties. All representations and
warranties made in, pursuant to or in connection with this Agreement shall
survive the execution, delivery and closing of this Agreement, and the issuance
of the Note for a period of two (2) years; provided, however, that the
representations and warranties made in Section 4.15 (Environmental) and 4.20
(Taxes) shall survive the applicable statutory period of limitations with
respect to any liabilities covered thereby.

         8.4 Severability of Provisions. Any provision of this Agreement which
is prohibited or unenforceable in any jurisdiction will, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

successors and assigns of the parties hereto, including, without limitation,
each transferee of all or any portion of the Note. The Company may not assign
its rights or delegate its obligations under this Agreement without the prior
written consent of the other parties hereto. A Lender may assign its rights and
delegate its obligations under this Agreement upon the Company's prior written
consent which consent will not be unreasonably withheld. The Parties agree that,
among other reasons, it will be reasonable for the Company to withhold such
consent if the proposed assignee is a competitor to the Company.

         8.6 Entire Agreement. This Agreement and the other documents delivered
pursuant hereto constitute the full and entire understanding and agreement
between the parties with regard to the subject matter hereof and thereof and
supersede and cancel all prior representations, alleged warranties, statements,
negotiations, undertakings, letters, acceptances, understandings, contracts and
communications, whether verbal or written, among the parties hereto and thereto
or their respective agents with respect to or in connection with the subject
matter hereof.

in accordance with the laws of said state, without regard to principles of
conflicts of law.

reference only and will not affect the construction of this Agreement.

         8.9 Counterparts. This Agreement may be executed in any number of
counterparts and by different parties hereto in separate counterparts, with the
same effect as if all parties had signed the same document. All such
counterparts shall be deemed an original, shall be construed together and shall
constitute one and the same instrument. Execution and delivery by facsimile
shall constitute good and valid execution and delivery unless and until replaced
or substituted by an original executed instrument.

         8.10 No Third-Party Beneficiaries. Nothing in this Agreement will
confer any third party beneficiary or other rights upon any Person (specifically
including any employees of the Company and its Subsidiaries) or entity that is
not a party to this Agreement.
