THIS WARRANT AND THE COMMON STOCK ISSUABLE UPON EXERCISE OF THIS WARRANT MAY NOT
BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
EFFECTIVE REGISTRATION STATEMENT AS TO THIS WARRANT UNDER SAID ACT OR AN OPINION

                                    adjustment as provided herein)

                          COMMON STOCK PURCHASE WARRANT

No. 2003-4                                         Issue Date: December 31, 2003

                  netGuru, Inc., a corporation organized under the laws of the
State of Delaware (the "Company"), hereby certifies that, for value received,
Silverman Heller Associates, or assigns (the "Holder"), is entitled, subject to
the terms set forth below, to purchase from the Company from and after the Issue
Date of this Warrant and at any time or from time to time before 5:00 p.m.,
Pacific Standard Time, through five (5) years after such date (the "Expiration
Date"), up to 50,000 fully paid and nonassessable shares of Common Stock of the
Company, at the Exercise Price (as defined below).

                  As used herein the following terms, unless the context
otherwise requires, have the following respective meanings:

                  (a) The term "Company" shall include netGuru, Inc. and any
corporation that shall succeed or assume the obligations of netGuru, Inc.
hereunder.

                  (b) The term "Common Stock" includes (a) the Company's Common
Stock, par value $.01 per share, and (b) any other securities into which or for
which any of the securities described in (a) may be converted or exchanged
pursuant to a plan of recapitalization, reorganization, merger, sale of assets
or otherwise.

                  (c) The term "Exercise Price" shall be as follows:

including the Expiration Date, the Holder shall be entitled to receive, upon
exercise of this Warrant in whole or in part, by delivery of an original or fax

                                       1
<PAGE>

         2. PROCEDURE FOR EXERCISE.

                  2.1 DELIVERY OF STOCK CERTIFICATES, ETC. ON EXERCISE. The
Company agrees that the shares of Common Stock purchased upon exercise of this
Warrant shall be deemed to be issued to the Holder as the record owner of such
shares as of the close of business on the date on which this Warrant shall have
been surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within ten (10) business days thereafter, the Company will cause to be
issued in the name of and delivered to the Holder, or as such Holder (upon
payment by such holder of any applicable transfer taxes) may direct in
compliance with applicable securities laws, a certificate or certificates for
the number of duly and validly issued, fully paid and nonassessable shares of
Common Stock to which such Holder shall be entitled on such exercise.

                  2.2 EXERCISE. Payment may be made in cash or by certified or
official bank check payable to the order of the Company equal to the applicable
aggregate Exercise Price, for the number of Common Shares specified in such form
and the Holder shall thereupon be entitled to receive the number of duly
authorized, validly issued, fully-paid and non-assessable shares of Common Stock
determined as provided herein.

         3. EFFECT OF REORGANIZATION.

                  3.1 REORGANIZATION, CONSOLIDATION, MERGER, ETC. In case at any
time or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, as a condition to the consummation of such a transaction, proper and
adequate provision shall be made by the Company whereby the Holder of this
Warrant, on the exercise hereof as provided in Section 1 at any time after the
consummation of such reorganization, consolidation or merger or the effective
date of such dissolution, as the case may be, shall receive, in lieu of the
Common Stock (or Other Securities) issuable on such exercise prior to such
consummation or such effective date, the stock and other securities and property
(including cash) to which such Holder would have been entitled upon such
consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant, immediately prior thereto.

                  3.2 CONTINUATION OF TERMS. Upon any reorganization,
consolidation, merger or transfer referred to in this Section 3, this Warrant
shall continue in full force and effect and the terms hereof shall be applicable
to the shares of stock and other securities and property receivable on the
exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case may be, and shall be binding upon the issuer of any such
stock or other securities, including, in the case of any such transfer, the
person acquiring all or substantially all of the properties or assets of the
Company.

         4. EXTRAORDINARY EVENTS REGARDING COMMON STOCK. In the event that the
Company shall (a) issue additional shares of the Common Stock as a dividend or
other distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such

                                       2
<PAGE>

event, the Exercise Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Exercise Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Exercise Price then in effect. The
Exercise Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 4.
The number of shares of Common Stock that the holder of this Warrant shall
thereafter, on the exercise hereof as provided in Section 1, be entitled to
receive shall be increased to a number determined by multiplying the number of
shares of Common Stock that would otherwise (but for the provisions of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the Exercise Price that would otherwise (but for the provisions of this
Section 4) be in effect, and (b) the denominator is the Exercise Price in effect
on the date of such exercise.

         5. RESERVATION OF STOCK, ETC. ISSUABLE ON EXERCISE OF WARRANT. The
Company will at all times reserve and keep available, solely for issuance and
delivery on the exercise of the Warrant, shares of Common Stock (or Other
Securities) from time to time issuable on the exercise of the Warrant.

         6. REPLACEMENT OF WARRANT. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of this Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

         7. PIGGY BACK REGISTRATION RIGHTS. Until the shares of Common Stock
underlying the Warrant are eligible for resale under Rule 144 of the Securities
Act of 1933, as amended, if the Company at any time proposes to register under
the Act any of its securities (other than in connection with a tender offer,
merger, or other acquisition, or a registration on Form S-4 or S-8, or any
successor form thereto) for sale for its own account, it will at such time give
prompt written notice to the Holder of its intention to do so. Upon the written
request of the Holder made within five (5) days after the date of any such
notice, the Company will use its reasonably diligent efforts to effect the
registration under the Act of all shares of Common Stock which the Company has
been so requested to register by the Holder, to the extent required to permit
the disposition of the shares of Common Stock to be so registered; PROVIDED
HOWEVER, that the Company may at any time withdraw or cease proceeding with any
such registration, if it shall at the same time withdraw or cease proceeding
with the registration of all other securities originally proposed to be
registered. If a registration pursuant to this Section involves an underwritten
offering of the securities being registered, whether or not for sale for the
account of the Company, to be distributed, on a firm commitment basis, by or
through one or more underwriters; and (ii) the managing underwriter of such
underwritten offering shall inform the Company and the Holder by letter of its
belief that the number of securities, if any, requested to be included for the
account of the Holder (and any other participating securities holders of the
Company) in such registration exceeds the number which can be sold in (or during
the time of) such offering, or that the inclusion would in the underwriter's
judgment adversely affect the marketing of the securities to be sold by the
Company, and the Holder and such other holders of securities, then the number of

                                       3
<PAGE>

securities to be included in the offering (except for shares to be issued by the
Company in an offering initiated by the Company) shall be reduced to the
required level with the participation in such offering to be pro rata among
Holder and other holders based upon the number of shares of securities each such
Holder or other holders requested to be included in such registration.

         8. MAXIMUM EXERCISE. Holder agrees to restrict its weekly sales of
shares of Common Stock issuable upon exercise this Warrant to no more than such
number of shares as equals ten percent (10%) of the average daily trading volume
of the Company's common stock for the five (5) days prior to its sale as
reported by Bloomberg, L.P.

         9. WARRANT AGENT. The Company may, by written notice to the each holder
of the Warrant, appoint an agent for the purpose of issuing Common Stock on the
exercise of this Warrant pursuant to Section 1 and thereafter any such issuance,
exchange or replacement, as the case may be, shall be made at such office by
such agent.

         10. TRANSFER ON THE COMPANY'S BOOKS. Until this Warrant is transferred
on the books of the Company, the Company may treat the registered holder hereof
as the absolute owner hereof for all purposes, notwithstanding any notice to the
contrary.

         11. NOTICES, ETC. All notices and other communications from the Company
to the Holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, at such address as may have been furnished to
the Company in writing by such holder or, until any such Holder furnishes to the
Company an address, then to, and at the address of, the last Holder of this
Warrant who has so furnished an address to the Company.

         12. VOLUNTARY ADJUSTMENT BY THE COMPANY. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

         13. MISCELLANEOUS. This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. This Warrant shall be governed by and construed in accordance with
the laws of State of California without regard to principles of conflicts of
laws. Any action brought concerning the transactions contemplated by this
Warrant shall be brought only in the state courts of California or in the
federal courts located in the state of California. In the event that any
provision of this Warrant is invalid or unenforceable under any applicable
statute or rule of law, then such provision shall be deemed inoperative to the
extent that it may conflict therewith and shall be deemed modified to conform
with such statute or rule of law. Any such provision which may prove invalid or
unenforceable under any law shall not affect the validity or enforceability of
any other provision of this Warrant. The headings in this Warrant are for
purposes of reference only, and shall not limit or otherwise affect any of the
terms hereof. The invalidity or unenforceability of any provision hereof shall
in no way affect the validity or enforceability of any other provision. The
Holder acknowledges that legal counsel participated in the preparation of this
Warrant and, therefore, stipulates that the rule of construction that
ambiguities are to be resolved against the drafting party shall not be applied
in the interpretation of this Warrant to favor any party against the other
party.
