follows:

                                            to the "Prime Rate" in effect from

                                            the best rate available at Silicon.
                                            The interest rate applicable to the
                                            Obligations shall change on each
                                            date there is a change in the Prime
                                            Rate.

to Silicon, as set forth in the Warrant to Purchase Stock and related documents
(including but not limited to an Anti-Dilution Agreement and Registration Rights
Agreement) being executed concurrently with this Agreement. If between the date
hereof and October 8, 1999, Borrower does not receive cash proceeds of at least
$7,000,000 in consideration of Borrower's issuance of Series E Preferred stock,
(i) Borrower shall provide Silicon with five-year warranty to purchase an
additional 8,000 shares of Borrower's Series E Preferred stock at $1.25 per
share (the "Additional Series E Warrants"), on terms acceptable to Silicon, and
(ii) the strike price of the Initial Series E Warrants shall be amended from
$2.50 per share to $1.25 per share. The Initial Series E Warrants and the
Additional Series E Warrants shall be deemed fully earned on the date(s) of

                  1.2    COMPANY REGISTRATION.

                         (a)      REGISTRATION.  If at any time or from time to
time, the Company shall determine to register any of its securities, for its own
account or the account of any of its shareholders, other than a registration on
Form S-1 or S-8 relating solely to employee stock option or purchase plans, or a
registration on Form S-4 relating solely to an SEC Rule 145 transaction, or a
registration on any other form (other than Form S-1, S-2, S-3 or S-18, or their
successor forms) or any successor to such forms, which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the Company
will:

                                  (i)    promptly  give to  each Holder  written
notice thereof (which shall include a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under the applicable blue

compliance), and in any underwriting involved therein, all the Registrable
Securities specified in a written request or requests, made within 30 days after
receipt of such written notice from the Company, by any Holder or Holders,
except as set forth in subsection 1.2(b) below.

                         (b)      UNDERWRITING. If the registration of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to subsection 1.2(a)(i). In such event the right of any
Holder to registration pursuant to this subsection 1.2 shall be conditioned upon

                         (a)      Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its best efforts
to cause such registration statement to become effective, and, upon the request
of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for up to 120 days.

                         (b)      Prepare and file with the SEC such amendments
and supplement to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                         (c)      Furnish to the Holders such numbers of copies
of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                         (d)      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 shall be reasonably
requested by the Holders, provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such state or jurisdictions.

                         (e)      In the event of any underwritten public
offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offering. Each Holder participating in such underwriting shall also enter into
and perform its obligations under such an agreement.

                         (f)      Notify each Holder of Registrable  Securities
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act or the happening of
any event 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 circumstance then
existing.

                  1.5    INDEMNIFICATION.

                         (a)      The  Company  will  indemnify  each  Holder of
Registrable Securities and each of its officers, directors and partners, and
each person controlling such Holder, with respect to which such registration,
qualification or compliance has been effected pursuant to this Rights Agreement,
and each underwriter, if any, and each person who controls any underwriter of
the Registrable Securities held by or issuable to such Holder, against all
claims, losses, expenses, damages and liabilities (or actions in respect
thereto) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any prospectus, offering circular or
other document (including any related registration statement, notification or
the like) incident to any such registration, qualification or compliance, or
based on
<PAGE>

any  omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statement therein not misleading,
or any violation or alleged violation by the Company of the Securities Act, the
Securities Exchange Act of 1934, as amended ("Exchange Act") or any state
securities law applicable to the Company or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any such state law and relating to
action or inaction required of the Company in connection with any such
registration, qualification of compliance, and will reimburse each such Holder,
each of its officers, directors and partners, and each person controlling such
Holder, each such underwriter and each person who controls any such underwriter,
within a reasonable amount of time after incurred for any reasonable legal and
any other expenses incurred in connection with investigating, defending or
settling any such claim, loss, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 1.5(a) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability, or
action if such settlement is effected without the consent of the Company (which
consent shall not be unreasonably withheld); and provided further, that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage or liability arises out of or is based on any untrue statement or
omission based upon written information furnished to the Company by an
instrument duly executed by such Holder or underwriter specifically for use
therein.

                         (b)      Each Holder will, if Registrable Securities
held by or issuable to such Holder are included in the securities, as to which
such registration, qualification or compliance is being effected, indemnify the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and partners and each person
controlling such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or 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 will reimburse the Company, such Holders, such directors,
officers, partners, persons or underwriters for any reasonable legal or any
other expenses incurred in connection with investigating, defending or settling
any such claim, loss, damage, liability or action, in each case to the extent,
but only to the extent, that such untrue statements (or alleged untrue
statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Company by an instrument
duly executed by such Holder specifically for use therein; provided, however,
that the indemnity agreement contained in this subsection 1.5(b) shall not apply
to amounts paid in settlement of any such claim, loss, damage, liability or
action if such settlement is effected without the consent of the Holder, (which
consent shall not be unreasonably withheld); and provided further, that the
total amount for which any Holder shall be liable under this subsection 1.5(b)
shall not in any event exceed the aggregate proceeds received by such Holder
from the sale of Registrable Securities held by such Holder in such
registration.
<PAGE>

                         (c)      Each party entitled to indemnification under
this subsection 1.5 (the "Indemnified Party") shall give notice to the party
required to provide indemnification (the "Indemnifying Party") promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom; provided that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall not
be unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, unless such failure resulted in
prejudice to the Indemnifying Party; and provided further, that an Indemnified
Party (together with all other Indemnified Parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the Indemnifying Party, if
representation of such Indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between such Indemnified Party and any other party represented by such
counsel in such proceeding. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation.

                  1.6    INFORMATION BY HOLDER. Any Holder or Holders of
Registrable Securities included in any registration shall promptly furnish to
the Company such information regarding such Holder or Holders and the
distribution proposed by such Holder or Holders as the Company may request in
writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

                  1.7    RULE 144 REPORTING. With a view to making available to
Holders the benefits of certain rules and regulations of the SEC which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees at all times to:

                         (a)      make and keep public information  available,
as those terms are understood and defined in SEC Rule 144, after 90 days after
the effective date of the first registration filed by the Company for an
offering of its securities to the general public;

                         (b)      file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements); and

                         (c)      so long as a Holder owns any Registrable
Securities, to furnish to such Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after 90 days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of
<PAGE>

the  Company, and such other reports and  documents so filed by the Company as
the Holder may reasonably request in complying with any rule or regulation of
the SEC allowing the Holder to sell any such securities without registration.

                  1.8    TRANSFER OF REGISTRATION RIGHTS. Holders' rights to
cause the Company to register their securities and keep information available,
granted to them by the Company under subsections 1.2 and 1.7 may be assigned to
a transferee or assignee of a Holder's Registrable Securities not sold to the
public, provided, that the Company is given written notice by such Holder at the
time of or within a reasonable time after said transfer, stating the name and
address of said transferee or assignee and identifying the securities with
respect to which such registration rights are being assigned. The Company may
prohibit the transfer of any Holders' rights under this subsection 1.8 to any
proposed transferee or assignee who the Company reasonably believes is a
competitor of the Company.

         2.       GENERAL.

                  2.1    WAIVERS AND AMENDMENTS. With the written consent of the
record or beneficial holders of at least a majority of the Registrable
Securities, the obligations of the Company and the rights of the Holders of the
Registrable Securities under this agreement may be waived (either generally or
in a particular instance, either retroactively or prospectively, and either for
a specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of its Board of Directors, may enter into
a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement;
provided, however, that no such modification, amendment or waiver shall reduce
the aforesaid percentage of Registrable Securities without the consent of all of
the Holders of the Registrable Securities. Upon the effectuation of each such
waiver, consent, agreement of amendment or modification, the Company shall
promptly give written notice thereof to the record holders of the Registrable
Securities who have not previously consented thereto in writing. This Agreement
or any provision hereof may be changed, waived, discharged, or terminated only
by a statement in writing signed by the party against which enforcement of the
change, waiver, discharge or termination is sought, except to the extent
provided in this subsection 2.1.

                  2.2    GOVERNING LAW. This Agreement shall be governed in all
respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

                  2.3    SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

                  2.4    ENTIRE AGREEMENT. Except as set forth below, this
Agreement and the other documents delivered pursuant hereto constitute the full
and entire understanding and agreement between the parties with regard to the
subjects hereof and thereof.
<PAGE>

                  2.5    NOTICES, ETC. All notices and other communications
required or permitted hereunder shall be in writing and shall be mailed by first
class mail, postage prepaid, certified or registered mail, return receipt
requested, addressed (a) if to Holder, at such Holder's address as set forth
below, or at such other address as such Holder shall have furnished to the
Company in writing, or (b) if to the Company, at the Company's address set forth
below, or at such other address as the Company shall have furnished to the
Holder in writing.

                  2.6    SEVERABILITY. In case any provision of this Agreement
shall be invalid, illegal, or unenforceable, the validity, legality and
enforceability of the remaining provisions of this Agreement or any provision of
the other Agreements shall not in any way be affected or impaired thereby,

                  2.7    TITLES AND SUBTITLES. The titles of the sections  and
subsections of this Agreement are for  convenience of reference only and are not
to be considered in construing this Agreement.

                  2.8    COUNTERPARTS.  This  Agreement may be  executed  in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument.
