Number of Shares:  _________________
Class of Stock:  Common
Warrant Price:  $_________ per share
Issue Date:  _______________________
Expiration Date: ___________________


          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 company (the "Company") at 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 Article 1.2, Holder shall also deliver to the
Company a check,  wire transfer (to an account  designated  by the Company),  or
other form of payment  acceptable to the Company for the aggregate Warrant Price
for the Shares being purchased.

          1.2 Conversion  Right. In lieu of exercising this Warrant as specified
in Article 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 Article 1.3.

          1.3 Fair Market Value.  If the  Company's  common stock is traded in a
public  market and the shares are common  stock,  the fair market  value of each
Share  shall be the  closing  price of a Share  reported  for the  business  day
immediately before Holder delivers its Notice of Exercise to the Company. If the
Company's common stock is 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
<PAGE>

          1.4 Delivery of  Certificate  and New Warrant.  Promptly  after Holder
exercises  or converts  this Warrant and, if  applicable,  the Company  receives
payment of the  aggregate  Warrant  Price,  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 Treatment of Warrant Upon Acquisition of 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 Treatment of Warrant at Acquisition.

                    A) Upon the written  request of the Company,  Holder  agrees
that, in the event of an  Acquisition in which the sole  consideration  is cash,
either (a) Holder shall  exercise its  conversion  or purchase  right under this
Warrant and such  exercise  will be deemed  effective  immediately  prior to the
consummation  of such  Acquisition  or (b) if Holder  elects not to exercise the
Warrant, this Warrant will expire upon the consummation of such Acquisition. The
Company shall provide the Holder with written notice of its request  relating to
the  foregoing  (together  with such  reasonable  information  as the Holder may
request in connection  with such  contemplated  Acquisition  giving rise to such
notice), which is to be delivered to Holder not less than ten (10) days prior to
the closing of the proposed Acquisition.

                    B) Upon the written  request of the Company,  Holder  agrees
that,  in the event of an  Acquisition  that is an "arms  length" sale of all or
substantially all of the Company's assets (and only its assets) to a third party
that is not an  Affiliate  (as  defined  below) of the  Company  (a "True  Asset
Sale"),  either (a) Holder shall exercise its conversion or purchase right under
this Warrant and such exercise will be deemed effective immediately prior to the
consummation  of such  Acquisition  or (b) if Holder  elects not to exercise the
Warrant,  this Warrant will continue  until the  Expiration  Date if the Company
continues as a going concern  following the closing of any such True Asset Sale.
The Company shall provide the Holder with written notice of its request relating
to the foregoing  (together with such  reasonable  information as the Holder may
request in connection  with such  contemplated  Acquisition  giving rise to such
notice), which is to be delivered to Holder not less than ten (10) days prior to
the closing of the proposed Acquisition.

                    C) Upon the  closing  of any  Acquisition  other  than those
particularly  described in subsections (A) and (B) above,  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 Warrant Price and/or number of Shares shall be adjusted
accordingly.

As used herein "Affiliate" shall mean any person or entity that owns or controls
directly or  indirectly  ten (10)  percent or more of the stock of Company,  any
person or entity that controls or is  controlled  by or is under common  control
with such persons or entities,  and each of such person's or entity's  officers,
directors, joint venturers or partners, as applicable.

                                       2

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

          2.1 Stock  Dividends,  Splits,  Etc. If the Company declares or pays a
dividend on the Shares payable in common stock, or other  securities,  then upon
exercise of this Warrant, for each Share 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 occurred.  If the Company subdivides the Shares by  reclassification or
otherwise  into a greater  number of  shares  or takes  any other  action  which
increase the amount of stock into which the Shares are  convertible,  the number
of shares  purchasable  hereunder  shall be  proportionately  increased  and the
Warrant Price shall be proportionately  decreased. If the outstanding shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be  proportionately  increased and the number
of Shares shall be proportionately decreased.

          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 Certificate 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 an
amendment  to this  Warrant  setting  forth  the  number  and  kind of such  new
securities  or other  property  issuable  upon  exercise or  conversion  of this
Warrant as a result of such  reclassification,  exchange,  substitution or other
event that results in a change of the number and/or class of securities issuable
upon exercise or conversion of this Warrant. The amendment to this 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 Warrant Price and to the number of securities or
property  issuable  upon  exercise of the new Warrant.  The  provisions  of this
Article 2.2 shall  similarly apply to successive  reclassifications,  exchanges,
substitutions, or other events.

          2.3 Intentionally Omitted.

          2.4  No  Impairment.  The  Company  shall  not,  by  amendment  of its
Certificate 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  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.

this  Warrant is not greater  than 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

          3.2 Notice of Certain Events.  If the Company proposes at any time (a)

property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for sale additional  shares of any class or series of the Company's
stock;  (c) to effect any  reclassification  or  recapitalization  of any of its

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 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

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  shall  have  certain   incidental,   or  "Piggyback,"
registration  rights and S-3 registration rights pursuant to and as set forth in
the  Company's  Registration  Rights  Agreement  with  holders of the  Company's
Subordinated Second Secured Promissory Notes.

          3.4 No  Shareholder  Rights.  Except as provided in this Warrant,  the
Holder  will not have any  rights  as a  shareholder  of the  Company  until the
exercise of this Warrant.

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

follows:

          4.1 Purchase for Own Account.  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 Act. Holder

acquiring this Warrant or the Shares.

                                       4
<PAGE>

          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
obtain  additional  information  (to  the  extent  the  Company  possessed  such
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 Holder
has  experience  as an investor in  securities  of companies in the  development
stage  and  acknowledges  that the  Holder  can bear the  economic  risk of such
Holder's  investment in this Warrant and its 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  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 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 Act.

          4.5 The Act. The Holder  understands  that this Warrant and the Shares
issuable upon exercise or conversion  hereof have not been registered  under the
Act in reliance upon a specific  exemption  therefrom,  which exemption  depends
upon, among other things, the bona fide nature of the Holder's investment intent
as expressed  herein.  The Holder  understands  that this Warrant and the Shares
issued upon any exercise or conversion hereof must be held  indefinitely  unless
subsequently  registered under the 1933 Act and qualified under applicable state
securities  laws, or unless exemption from such  registration and  qualification
are otherwise available.

opinion of counsel if the  transfer is to Silicon  Valley  Bancshares  (Holder's

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
