--------------------------------------------------------------------------------

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED OR ANY APPLICABLE STATE SECURITIES LAW,
AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE
REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT TO RULE 144 AND AN EXEMPTION
UNDER APPLICABLE STATE LAW OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.


                            WARRANT TO PURCHASE STOCK

Corporation:  Syntellect Inc., a Delaware corporation
Number of Shares:  30,000
Class of Stock:  Common
Initial Exercise Price:
The closing price of the Shares reported for the business day immediately before
the Issue Date, which is $1.17 per share
Issue Date:  May 14, 2002
Expiration Date: May 14, 2007


         THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase the number of fully paid and nonassessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth in this Warrant.

ARTICLE 1. EXERCISE.

                  1.1 Method of Exercise. Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

                  1.2 Conversion Right. In lieu of exercising this Warrant as
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share. The fair market value of the Shares
shall be determined pursuant to Section 1.3.

                  1.3 Fair Market Value. If the Shares are traded in a public
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are


                                       1
<PAGE>
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not traded in a public
market, the Board of Directors of the Company shall determine fair market value
in its reasonable good faith judgment.

                  1.4 Delivery of Certificate and New Warrant. Promptly after
Holder exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

                  1.5 Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company shall execute and deliver, in lieu of this Warrant, a new warrant of
like tenor.

                  1.6 Assumption on Sale, Merger, or Consolidation of the
Company.

                      1.6.1 "Acquisition". For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

                      1.6.2 Assumption of Warrant. Upon the closing of any
Acquisition, the successor entity shall assume the obligations of this Warrant,
and this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition and subsequent closing. The Initial Exercise
Price and/or number of Shares shall be adjusted accordingly.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

                      2.1 Stock Dividends, Splits, Etc. If the Company declares
or pays a dividend on its common stock (or the Shares if the Shares are
securities other than common stock) payable in common stock, or other
securities, subdivides the outstanding common stock into a greater amount of
common stock, or, if the Shares are securities other than common stock,
subdivides the Shares in a transaction that increases the amount of common stock
into which the Shares are convertible, then upon exercise of this Warrant, for
each Share


                                       2
<PAGE>
acquired, Holder shall receive, without cost to Holder, the total number and
kind of securities to which Holder would have been entitled had Holder owned the
Shares of record as of the date the dividend or subdivision occurred. If the
outstanding shares are combined or consolidated, by reclassification or
otherwise, into a lesser number of shares, the Initial Exercise Price shall be
proportionately increased.

                      2.2 Reclassification, Exchange, Combinations or
Substitution. Upon any reclassification, exchange, substitution, or other event
that results in a change of the number and/or class of the securities issuable
upon exercise or conversion of this Warrant, Holder shall be entitled to
receive, upon exercise or conversion of this Warrant, the number and kind of
securities and property that Holder would have received for the Shares if this
Warrant had been exercised immediately before such reclassification, exchange,
substitution, or other event. Such an event shall include any automatic
conversion of the outstanding or issuable securities of the Company of the same
class or series as the Shares to common stock pursuant to the terms of the
Company's Articles of Incorporation upon the closing of a registered public
offering of the Company's common stock. The Company or its successor shall
promptly issue to Holder a new Warrant for such new securities or other
property. The new Warrant shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
2 including, without limitation, adjustments to the Initial Exercise Price and
to the number of securities or property issuable upon exercise of the new
Warrant. The provisions of this Section 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events.

                      2.3 Adjustments for Diluting Issuances. The Warrant Price
and the number of Shares issuable upon exercise of this Warrant or, if the
Shares are Preferred Stock, the number of shares of common stock issuable upon
conversion of the Shares, shall be subject to adjustment, from time to time in
the manner set forth on Exhibit A in the event of Diluting Issuances (as defined
on Exhibit A).

                      2.4 No Impairment. The Company shall not, by amendment of
its Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment.

                      2.5 Fractional Shares. No fractional Shares shall be
issuable upon exercise or conversion of the Warrant and the number of Shares to
be issued shall be rounded down to the nearest whole Share. If a fractional
share interest arises upon any exercise or conversion of the Warrant, the
Company


                                       3
<PAGE>
shall eliminate such fractional share interest by paying Holder the amount
computed by multiplying the fractional interest by the fair market value of a
full Share.

                      2.6 Certificate as to Adjustments. Upon each adjustment of
the Warrant Price, the Company shall promptly notify Holder in writing, and, at
the Company's expense, promptly compute such adjustment, and furnish Holder with
a certificate of its Chief Financial Officer setting forth such adjustment and
the facts upon which such adjustment is based. The Company shall, upon written
request, furnish Holder a certificate setting forth the Warrant Price in effect
upon the date thereof and the series of adjustments leading to such Warrant
Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

                      3.1 Representations and Warranties. The Company represents
and warrants to the Holder as follows:

                          (a) The initial Warrant Price referenced on the first
page of this Warrant is not greater than (i) the price per share at which the
Shares were last issued in an arms-length transaction in which at least $500,000
of the Shares were sold and (ii) the fair market value of the Shares as of the
date of this Warrant.

                          (b) All Shares which may be issued upon the exercise
of the purchase right represented by this Warrant, and all securities, if any,
issuable upon conversion of the Shares, shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws.

                          (c) The Capitalization Table previously provided to
Holder remains true and complete as of the Issue Date.

                      3.2 Notice of Certain Events. If the Company proposes at
any time (a) to declare any dividend or distribution upon its common stock,
whether in cash, property, stock, or other securities and whether or not a
regular cash dividend; (b) to offer for subscription pro rata to the holders of
any class or series of its stock any additional shares of stock of any class or
series or other rights; (c) to effect any reclassification or recapitalization
of common stock; (d) to merge or consolidate with or into any other corporation,
or sell, lease, license, or convey all or substantially all of its assets, or to
liquidate, dissolve or wind up; or (e) offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give Holder (1) at least 10 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of common


                                       4
<PAGE>
stock will be entitled thereto) or for determining rights to vote, if any, in
respect of the matters referred to in (c) and (d) above; (2) in the case of the
matters referred to in (c) and (d) above at least 10 days prior written notice
of the date when the same will take place (and specifying the date on which the
holders of common stock will be entitled to exchange their common stock for
securities or other property deliverable upon the occurrence of such event); and
(3) in the case of the matter referred to in (e) above, the same notice as is
given to the holders of such registration rights.

                      3.3 Registration Under Securities Act of 1933, as amended.
The Company agrees that the Shares or, if the Shares are convertible into common
stock of the Company, such common stock, shall be subject to the registration
rights set forth on Exhibit B.

ARTICLE 4. REPRESENTATIONS, WARRANTIES OF THE HOLDER. The Holder represents and
warrants to the Company as follows:

         4.1 Purchase for Own Account. Except for transfers to Holder's
affiliates, this Warrant and the securities to be acquired upon exercise of this
Warrant by the Holder will be acquired for investment for the Holder's account,
not as a nominee or agent, and not with a view to the public resale or
distribution within the meaning of the 1933 Act, and the Holder has no present
intention of selling, granting any participation in, or otherwise distributing
the same. If not an individual, the Holder also represents that the Holder has
not been formed for the specific purpose of acquiring this Warrant or the
Shares.

         4.2 Disclosure of Information. The Holder has received or has had full
access to all the information it considers necessary or appropriate to make an
informed investment decision with respect to the acquisition of this Warrant and
its underlying securities. The Holder further has had an opportunity to ask
questions and receive answers from the Company regarding the terms and
conditions of the offering of this Warrant and its underlying securities and to

information or could acquire it without unreasonable effort or expense)
necessary to verify any information furnished to the Holder or to which the
Holder has access.

         4.3 Investment Experience. The Holder understands that the purchase of
this Warrant and its underlying securities involves substantial risk. The

underlying securities and has such knowledge and experience in financial or
business matters that the Holder is capable of evaluating the merits and risks
of its investment in this Warrant and its underlying securities and/or (ii) has
a preexisting personal or business relationship with the Company and certain of
its officers, directors or controlling persons of a nature and duration that
enables the


                                       5
<PAGE>
Holder to be aware of the character, business acumen and financial circumstances
of such persons.

         4.4 Accredited Investor Status. The Holder is an "accredited investor"
within the meaning of Regulation D promulgated under the 1933 Act.

ARTICLE 5. MISCELLANEOUS.

and from time to time on or before the Expiration Date.

         5.2 Legends. This Warrant and the Shares (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) shall be
imprinted with a legend in substantially the following form:

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
         AS AMENDED OR UNDER ANY APPLICABLE STATE LAWS, AND MAY NOT BE SOLD,
         PLEDGED OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION
         THERE OF UNDER SUCH ACT AND AN EXEMPTION UNDER APPLICABLE STATE LAW OR
         PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY
         TO THE CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT
         REQUIRED.

         5.3 Compliance with Securities Laws on Transfer. This Warrant and the
Shares issuable upon exercise of this Warrant (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) may not be
transferred or assigned in whole or in part without compliance with applicable
federal and state securities laws by the transferor and the transferee
(including, without limitation, the delivery of investment representation
letters and legal opinions reasonably satisfactory to the Company, as reasonably
requested by the Company). The Company shall not require Holder to provide an
opinion of counsel if the transfer is to an affiliate of Holder or if there is
no material question as to the availability of current information as referenced
in Rule 144(c), Holder represents that it has complied with Rule 144(d) and (e)
in reasonable detail, the selling broker represents that it has complied with
Rule 144(f), and the Company is provided with a copy of Holder's notice of
proposed sale.

         5.4 Transfer Procedure. Subject to the provisions of Section 5.3, upon
receipt by Holder of the executed Warrant, Holder will transfer all of this
Warrant or the Shares issuable upon exercise of this Warrant (or the securities

<PAGE>
and upon providing Company with written notice, Silicon Valley Bancshares may
transfer all or part of this Warrant or the Shares issuable upon exercise of
this Warrant (or the Shares issuable directly or indirectly, upon conversion of
the Shares, if any) to The Silicon Valley Bank Foundation, or to any affiliate
of Holder, or to any other transferee, provided, however, if Holder transfers
this Warrant to any transferee which is not an affiliate of Holder, Holder will
give the Company notice of the portion of the Warrant being transferred with the
name, address and taxpayer identification number of the transferee and will
surrender this Warrant to the Company for reissuance to the transferee(s) (and
Holder if applicable). The Company may refuse to transfer this Warrant or the
Shares to any person who directly competes with the Company, unless, in either
case, the stock of the Company is publicly traded.

the Holder, or vice versa, shall be deemed delivered and effective when given
personally or mailed by first-class registered or certified mail, postage

concerning the terms and provisions of this Warrant, the party prevailing in
such dispute shall be entitled to collect from the other party all costs
incurred in such dispute, including reasonable attorney's fees.

         5.8 Automatic Conversion upon Expiration. In the event that, upon the
Expiration Date, the fair market value of one Share (or other security issuable
upon the exercise hereof) as determined in accordance with Section 1.3 above is
greater than the Exercise Price in effect on such date, then this Warrant shall
automatically be deemed on and as of such date to be converted pursuant to
Section 1.2 above as to all Shares (or such other securities) for which it shall
not previously have been exercised or converted, and the Company shall promptly
deliver a certificate representing the Shares (or such other securities) issued

                      (a) The term "register," "registered," and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the Securities Act of 1933, as
amended (the "Securities Act"), and the declaration or ordering of effectiveness
of such registration statement or document;

                      (b) The term "Registrable Securities" means (i) the Shares
(if Common Stock) or all shares of Common Stock of the Company issuable or
issued upon conversion of the Shares and (ii) any Common Stock of the Company
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued as) a dividend or other distribution with respect
to, or in exchange for or in replacement of, any stock referred to in (i).

                      (c) The terms "Holder" or "Holders" means the Purchaser or
qualifying transferees under subsection 1.8 hereof who hold Registrable
Securities.


                                       2
<PAGE>
                      (d) The term "SEC" means the Securities and Exchange
Commission.

                 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 sky or other state
securities laws); and

                        (ii) include in such registration (and 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 such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company and the other shareholders distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting by the Company.

                  1.3 Expenses of Registration. All expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Section 1 including without limitation, all registration, filing and
qualification fees, printing expenses, fees and disbursements of counsel for the
Company and expenses of any special audits incidental to or required by such
registration, shall be borne by the Company except the Company shall not be
required to pay


                                       3
<PAGE>
underwriters' fees, discounts or commissions relating to Registrable Securities.
All expenses of any registered offering not otherwise borne by the Company shall
be borne pro rata among the Holders participating in the offering and the
Company.

                 1.4 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this
Registration Rights Agreement, the Company will keep each Holder participating
therein advised in writing as to the initiation of each registration,
qualification and compliance and as to the completion thereof. Except as
otherwise provided in subsection 1.3, at its expense the Company will:

                      (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
supplements 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 states 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


                                       4
<PAGE>
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

                 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 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


                                       5
<PAGE>
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 statement (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.

                      (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


                                       6
<PAGE>
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 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


                                       7
<PAGE>
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.

required or permitted hereunder shall be in writing and shall be mailed by first
class mail, postage prepaid, certified or registered mail, return receipt

Company in writing, or (b) if

<PAGE>
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
Agreement s shall not in any way be affected or impaired thereby.
