                             STOCK PURCHASE WARRANT

      THIS CERTIFIES THAT, for value received, ______________ or its registered
assigns, is entitled to purchase from Nayna Networks, Inc. a Nevada corporation
(the "Company"), at any time or from time to time during the period specified in
Paragraph 2 hereof, ___________ (__________) fully paid and nonassessable shares
of the Company's Common Stock, par value $.0001 per share (the "Common Stock"),
at an exercise price per share equal to $1.00 (the "Exercise Price"). The term
"Warrant Shares," as used herein, refers to the shares of Common Stock
purchasable hereunder. The Warrant Shares and the Exercise Price are subject to
adjustment as provided in Paragraph 4 hereof. The term "Warrants" means this
Warrant and the other warrants issued pursuant to that certain Securities
Purchase Agreement, dated November 17, 2005, by and among the Company and the
Buyers listed on the execution page thereof (the "Securities Purchase
Agreement").

      This Warrant is subject to the following terms, provisions, and
conditions:

      1. Manner of Exercise; Issuance of Certificates; Payment for Shares.
Subject to the provisions hereof, this Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant, together with a
completed exercise agreement in the form attached hereto (the "Exercise
Agreement"), to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the holder hereof), and upon (i)
payment to the


<PAGE>

Company in cash, by certified or official bank check or by wire transfer for the
account of the Company of the Exercise Price for the Warrant Shares specified in
the Exercise Agreement or (ii) if the resale of the Warrant Shares by the holder
is not then registered pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "Securities Act"), delivery to the
Company of a written notice of an election to effect a "Cashless Exercise" (as
defined in Section 11(c) below) for the Warrant Shares specified in the Exercise
Agreement. The Warrant Shares so purchased shall be deemed to be issued to the
holder hereof or such holder's designee, as the record owner of such shares, as
of the close of business on the date on which this Warrant shall have been
surrendered, the completed Exercise Agreement shall have been delivered, and
payment shall have been made for such shares as set forth above. Certificates
for the Warrant Shares so purchased, representing the aggregate number of shares
specified in the Exercise Agreement, shall be delivered to the holder hereof
within a reasonable time, not exceeding five (5) business days, after this
Warrant shall have been so exercised. The certificates so delivered shall be in
such denominations as may be requested by the holder hereof and shall be
registered in the name of such holder or such other name as shall be designated
by such holder. If this Warrant shall have been exercised only in part, then,
unless this Warrant has expired, the Company shall, at its expense, at the time
of delivery of such certificates, deliver to the holder a new Warrant
representing the number of shares with respect to which this Warrant shall not
then have been exercised. In addition to all other available remedies at law or
in equity, if the Company fails to deliver certificates for the Warrant Shares
within five (5) business days after this Warrant is exercised, then the Company
shall pay to the holder in cash a penalty (the "Penalty") equal to 1% of the
number of Warrant Shares that the holder is entitled to multiplied by the Market
Price (as hereinafter defined) for each day that the Company fails to deliver
certificates for the Warrant Shares. For example, if the holder is entitled to
100,000 Warrant Shares and the Market Price is $2.00, then the Company shall pay
to the holder $2,000 for each day that the Company fails to deliver certificates
for the Warrant Shares. The Penalty shall be paid to the holder by the fifth day
of the month following the month in which it has accrued.

      Notwithstanding anything in this Warrant to the contrary, in no event
shall the holder of this Warrant be entitled to exercise a number of Warrants
(or portions thereof) in excess of the number of Warrants (or portions thereof)
upon exercise of which the sum of (i) the number of shares of Common Stock
beneficially owned by the holder and its affiliates (other than shares of Common
Stock which may be deemed beneficially owned through the ownership of the
unexercised Warrants and the unexercised or unconverted portion of any other
securities of the Company (including the Notes (as defined in the Securities
Purchase Agreement)) subject to a limitation on conversion or exercise analogous
to the limitation contained herein) and (ii) the number of shares of Common
Stock issuable upon exercise of the Warrants (or portions thereof) with respect
to which the determination described herein is being made, would result in
beneficial ownership by the holder and its affiliates of more than 4.9% of the
outstanding shares of Common Stock. For purposes of the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13D-G
thereunder, except as otherwise provided in clause (i) of the preceding
sentence. Notwithstanding anything to the contrary contained herein, the
limitation on exercise of this Warrant set forth herein may not be amended
without (i) the written consent of the holder hereof and the Company and (ii)
the approval of a majority of shareholders of the Company.

      2. Period of Exercise. This Warrant is exercisable at any time or from
time to time on or after the date on which this Warrant is issued and delivered
pursuant to the terms of the Securities Purchase Agreement and before 6:00 p.m.,
New York, New York time on the fifth (5th) anniversary of the date of issuance
(the "Exercise Period").

      3. Certain Agreements of the Company. The Company hereby covenants and
agrees as follows:

      (a) Shares to be Fully Paid. All Warrant Shares will, upon issuance in
accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, and charges with respect to the
issue thereof.

      (b) Reservation of Shares. During the Exercise Period, the Company shall
at all times have authorized, and reserved for the purpose of issuance upon
exercise of this Warrant, a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

      (c) Listing. The Company shall promptly secure the listing of the shares
of Common Stock issuable upon exercise of the Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

      (d) Certain Actions Prohibited. The Company will not, by amendment of its
charter or through any 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 by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common Stock receivable upon
the exercise of this Warrant above the Exercise Price then in effect, and (ii)
will take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

      (e) Successors and Assigns. This Warrant will be binding upon any entity
succeeding to the Company by merger, consolidation, or acquisition of all or
substantially all the Company's assets.

      4. Antidilution Provisions. During the Exercise Period, the Exercise Price
and the number of Warrant Shares shall be subject to adjustment from time to
time as provided in this Paragraph 4.

                                      -3-
<PAGE>

      In the event that any adjustment of the Exercise Price as required herein
results in a fraction of a cent, such Exercise Price shall be rounded up to the
nearest cent.

      (a) Adjustment of Exercise Price and Number of Shares upon Issuance of
Common Stock. Except as otherwise provided in Paragraphs 4(c) and 4(e) hereof,
if and whenever on or after the date of issuance of this Warrant, the Company
issues or sells, or in accordance with Paragraph 4(b) hereof is deemed to have
issued or sold, any shares of Common Stock for no consideration or for a
consideration per share (before deduction of reasonable expenses or commissions
or underwriting discounts or allowances in connection therewith) less than the
Market Price on the date of issuance (a "Dilutive Issuance"), then immediately
upon the Dilutive Issuance, the Exercise Price will be reduced to a price
determined by multiplying the Exercise Price in effect immediately prior to the
Dilutive Issuance by a fraction, (i) the numerator of which is an amount equal
to the sum of (x) the number of shares of Common Stock actually outstanding
immediately prior to the Dilutive Issuance, plus (y) the quotient of the
aggregate consideration, calculated as set forth in Paragraph 4(b) hereof,
received by the Company upon such Dilutive Issuance divided by the Market Price
in effect immediately prior to the Dilutive Issuance, and (ii) the denominator
of which is the total number of shares of Common Stock Deemed Outstanding (as
defined below) immediately after the Dilutive Issuance.

      (b) Effect on Exercise Price of Certain Events. For purposes of
determining the adjusted Exercise Price under Paragraph 4(a) hereof, the
following will be applicable:

      (i) Issuance of Rights or Options. If the Company in any manner issues or
grants any warrants, rights or options, whether or not immediately exercisable,
to subscribe for or to purchase Common Stock or other securities convertible
into or exchangeable for Common Stock ("Convertible Securities") (such warrants,
rights and options to purchase Common Stock or Convertible Securities are
hereinafter referred to as "Options") and the price per share for which Common
Stock is issuable upon the exercise of such Options is less than the Market
Price on the date of issuance or grant of such Options, then the maximum total
number of shares of Common Stock issuable upon the exercise of all such Options
will, as of the date of the issuance or grant of such Options, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share. For purposes of the preceding sentence, the "price per share for which
Common Stock is issuable upon the exercise of such Options" is determined by
dividing (i) the total amount, if any, received or receivable by the Company as
consideration for the issuance or granting of all such Options, plus the minimum
aggregate amount of additional consideration, if any, payable to the Company
upon the exercise of all such Options, plus, in the case of Convertible
Securities issuable upon the exercise of such Options, the minimum aggregate
amount of additional consideration payable upon the conversion or exchange
thereof at the time such Convertible Securities first become convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise of all such Options (assuming full conversion of
Convertible Securities, if applicable). No further adjustment to the Exercise
Price will be made upon the actual issuance of such Common Stock upon the
exercise of such Options or upon the conversion or exchange of Convertible
Securities issuable upon exercise of such Options.

      (ii) Issuance of Convertible Securities. If the Company in any manner
issues or sells any Convertible Securities, whether or not immediately
convertible (other

                                      -4-
<PAGE>

than where the same are issuable upon the exercise of Options) and the price per
share for which Common Stock is issuable upon such conversion or exchange is
less than the Market Price on the date of issuance, then the maximum total
number of shares of Common Stock issuable upon the conversion or exchange of all
such Convertible Securities will, as of the date of the issuance of such
Convertible Securities, be deemed to be outstanding and to have been issued and
sold by the Company for such price per share. For the purposes of the preceding
sentence, the "price per share for which Common Stock is issuable upon such
conversion or exchange" is determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or sale
of all such Convertible Securities, plus the minimum aggregate amount of
additional consideration, if any, payable to the Company upon the conversion or
exchange thereof at the time such Convertible Securities first become
convertible or exchangeable, by (ii) the maximum total number of shares of
Common Stock issuable upon the conversion or exchange of all such Convertible
Securities. No further adjustment to the Exercise Price will be made upon the
actual issuance of such Common Stock upon conversion or exchange of such
Convertible Securities.

      (iii) Change in Option Price or Conversion Rate. If there is a change at
any time in (i) the amount of additional consideration payable to the Company
upon the exercise of any Options; (ii) the amount of additional consideration,
if any, payable to the Company upon the conversion or exchange of any
Convertible Securities; or (iii) the rate at which any Convertible Securities
are convertible into or exchangeable for Common Stock (other than under or by
reason of provisions designed to protect against dilution), the Exercise Price
in effect at the time of such change will be readjusted to the Exercise Price
which would have been in effect at such time had such Options or Convertible
Securities still outstanding provided for such changed additional consideration
or changed conversion rate, as the case may be, at the time initially granted,
issued or sold.

      (iv) Treatment of Expired Options and Unexercised Convertible Securities.
If, in any case, the total number of shares of Common Stock issuable upon
exercise of any Option or upon conversion or exchange of any Convertible
Securities is not, in fact, issued and the rights to exercise such Option or to
convert or exchange such Convertible Securities shall have expired or
terminated, the Exercise Price then in effect will be readjusted to the Exercise
Price which would have been in effect at the time of such expiration or
termination had such Option or Convertible Securities, to the extent outstanding
immediately prior to such expiration or termination (other than in respect of
the actual number of shares of Common Stock issued upon exercise or conversion
thereof), never been issued.

      (v) Calculation of Consideration Received. If any Common Stock, Options or
Convertible Securities are issued, granted or sold for cash, the consideration
received therefor for purposes of this Warrant will be the amount received by
the Company therefor, before deduction of reasonable commissions, underwriting
discounts or allowances or other reasonable expenses paid or incurred by the
Company in connection with such issuance, grant or sale. In case any Common
Stock, Options or Convertible Securities are issued or sold for a consideration
part or all of which shall be other than cash, the amount of the consideration
other than cash received by the Company will be the fair value of such
consideration, except where such consideration consists of securities, in which
case the amount of consideration received by the Company will be the Market
Price thereof as of the date of receipt. In case any Common Stock, Options or
Convertible Securities are issued in connection with any acquisition, merger or

                                      -5-

<PAGE>

consolidation in which the Company is the surviving corporation, the amount of
consideration therefor will be deemed to be the fair value of such portion of
the net assets and business of the non-surviving corporation as is attributable
to such Common Stock, Options or Convertible Securities, as the case may be. The
fair value of any consideration other than cash or securities will be determined
in good faith by the Board of Directors of the Company.

      (vi) Exceptions to Adjustment of Exercise Price. No adjustment to the
Exercise Price will be made (i) upon the exercise of any warrants, options or
convertible securities granted, issued and outstanding on the date of issuance
of this Warrant; (ii) upon the grant or exercise of any stock or options which
may hereafter be granted or exercised under any employee benefit plan, stock
option plan or restricted stock plan of the Company now existing or to be
implemented in the future, so long as the issuance of such stock or options is
approved by a majority of the independent members of the Board of Directors of
the Company or a majority of the members of a committee of independent directors
established for such purpose; or (iii) upon the issuance of securities in
connection with a merger, consolidation or purchase of assets, or in connection
with any strategic partnership or joint venture (the primary purpose of which is
not to raise equity capital), or in connection with the disposition or
acquisition of a business, product or license by the Company, so long as the
issuance of such securities is approved by a majority of the independent members
of the Board of Directors of the Company or a majority of the members of a
committee of independent directors established for such purpose; (iv) upon the
exercise of the Warrants.

      (c) Subdivision or Combination of Common Stock. If the Company at any time
subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) the shares of Common Stock
acquirable hereunder into a greater number of shares, then, after the date of
record for effecting such subdivision, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company at any
time combines (by reverse stock split, recapitalization, reorganization,
reclassification or otherwise) the shares of Common Stock acquirable hereunder
into a smaller number of shares, then, after the date of record for effecting
such combination, the Exercise Price in effect immediately prior to such
combination will be proportionately increased.

      (d) Adjustment in Number of Shares. Upon each adjustment of the Exercise
Price pursuant to the provisions of this Paragraph 4, the number of shares of
Common Stock issuable upon exercise of this Warrant shall be adjusted by
multiplying a number equal to the Exercise Price in effect immediately prior to
such adjustment by the number of shares of Common Stock issuable upon exercise
of this Warrant immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

      (e) Consolidation, Merger or Sale. In case of any consolidation of the
Company with, or merger of the Company into any other corporation, or in case of
any sale or conveyance of all or substantially all of the assets of the Company
other than in connection with a plan of complete liquidation of the Company,
then as a condition of such consolidation, merger or sale or conveyance,
adequate provision will be made whereby the holder of this Warrant will have the
right to acquire and receive upon exercise of this Warrant in lieu of the shares
of Common Stock immediately theretofore acquirable upon the exercise of this
Warrant, such shares of stock, securities or assets as may be issued or payable
with respect to or in exchange for the number of shares of Common Stock
immediately theretofore acquirable and receivable

                                      -6-
<PAGE>

upon exercise of this Warrant had such consolidation, merger or sale or
conveyance not taken place. In any such case, the Company will make appropriate
provision to insure that the provisions of this Paragraph 4 hereof will
thereafter be applicable as nearly as may be in relation to any shares of stock
or securities thereafter deliverable upon the exercise of this Warrant. The
Company will not effect any consolidation, merger or sale or conveyance unless
prior to the consummation thereof, the successor corporation (if other than the
Company) assumes by written instrument the obligations under this Paragraph 4
and the obligations to deliver to the holder of this Warrant such shares of
stock, securities or assets as, in accordance with the foregoing provisions, the
holder may be entitled to acquire.

      (f) Distribution of Assets. In case the Company shall declare or make any
distribution of its assets (including cash) to holders of Common Stock as a
partial liquidating dividend, by way of return of capital or otherwise, then,
after the date of record for determining shareholders entitled to such
distribution, but prior to the date of distribution, the holder of this Warrant
shall be entitled upon exercise of this Warrant for the purchase of any or all
of the shares of Common Stock subject hereto, to receive the amount of such
assets which would have been payable to the holder had such holder been the
holder of such shares of Common Stock on the record date for the determination
of shareholders entitled to such distribution.

      (g) Notice of Adjustment. Upon the occurrence of any event which requires
any adjustment of the Exercise Price, then, and in each such case, the Company
shall give notice thereof to the holder of this Warrant, which notice shall
state the Exercise Price resulting from such adjustment and the increase or
decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Such calculation shall be certified
by the Chief Financial Officer of the Company.

      (h) Minimum Adjustment of Exercise Price. No adjustment of the Exercise
Price shall be made in an amount of less than 1% of the Exercise Price in effect
at the time such adjustment is otherwise required to be made, but any such
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

      (i) No Fractional Shares. No fractional shares of Common Stock are to be
issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable
in an amount equal to the same fraction of the Market Price of a share of Common
Stock on the date of such exercise.

      (j) Other Notices. In case at any time:

      (i) the Company shall declare any dividend upon the Common Stock payable
in shares of stock of any class or make any other distribution (including
dividends or distributions payable in cash out of retained earnings) to the
holders of the Common Stock;

      (ii) the Company shall offer for subscription pro rata to the holders of
the Common Stock any additional shares of stock of any class or other rights;

                                      -7-
<PAGE>

      (iii) there shall be any capital reorganization of the Company, or
reclassification of the Common Stock, or consolidation or merger of the Company
with or into, or sale of all or substantially all its assets to, another
corporation or entity; or

      (iv) there shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Company;

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution, or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Common Stock for stock
or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such notice shall be given at least 30 days
prior to the record date or the date on which the Company's books are closed in
respect thereto. Failure to give any such notice or any defect therein shall not
affect the validity of the proceedings referred to in clauses (i), (ii), (iii)
and (iv) above.

      (k) Certain Events. If any event occurs of the type contemplated by the
adjustment provisions of this Paragraph 4 but not expressly provided for by such
provisions, the Company will give notice of such event as provided in Paragraph
4(g) hereof, and the Company's Board of Directors will make an appropriate
adjustment in the Exercise Price and the number of shares of Common Stock
acquirable upon exercise of this Warrant so that the rights of the holder shall
be neither enhanced nor diminished by such event.

      (l) Certain Definitions.

      (i) "Common Stock Deemed Outstanding" shall mean the number of shares of
Common Stock actually outstanding (not including shares of Common Stock held in
the treasury of the Company), plus (x) pursuant to Paragraph 4(b)(i) hereof, the
maximum total number of shares of Common Stock issuable upon the exercise of
Options, as of the date of such issuance or grant of such Options, if any, and
(y) pursuant to Paragraph 4(b)(ii) hereof, the maximum total number of shares of
Common Stock issuable upon conversion or exchange of Convertible Securities, as
of the date of issuance of such Convertible Securities, if any.

      (ii) "Market Price," as of any date, (i) means the average of the last
reported sale prices for the shares of Common Stock on the OTCBB for the five
(5) Trading Days immediately preceding such date as reported by Bloomberg, or
(ii) if the OTCBB is not the principal trading market for the shares of Common
Stock, the average of the last reported sale prices on the principal trading
market for the Common Stock during the same period as reported by Bloomberg, or
(iii) if market value cannot be calculated as of such date on any of the
foregoing bases, the Market Price shall be the fair market value as reasonably
determined in good faith by (a) the Board of Directors of the Company or, at the
option of a majority-in-interest of the holders of the outstanding Warrants by
(b) an independent investment bank of nationally

                                      -8-
<PAGE>

recognized standing in the valuation of businesses similar to the business of
the corporation. The manner of determining the Market Price of the Common Stock
set forth in the foregoing definition shall apply with respect to any other
security in respect of which a determination as to market value must be made
hereunder.

      (iii) "Common Stock," for purposes of this Paragraph 4, includes the
Common Stock, par value $.0001 per share, and any additional class of stock of
the Company having no preference as to dividends or distributions on
liquidation, provided that the shares purchasable pursuant to this Warrant shall
include only shares of Common Stock, par value $.0001 per share, in respect of
which this Warrant is exercisable, or shares resulting from any subdivision or
combination of such Common Stock, or in the case of any reorganization,
reclassification, consolidation, merger, or sale of the character referred to in
Paragraph 4(e) hereof, the stock or other securities or property provided for in
such Paragraph.

      5. Issue Tax. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

6. No Rights or Liabilities as a Shareholder. This Warrant shall not entitle the
holder hereof to any voting rights or other rights as a shareholder of the
Company. No provision of this Warrant, in the absence of affirmative action by
the holder hereof to purchase Warrant Shares, and no mere enumeration herein of
the rights or privileges of the holder hereof, shall give rise to any liability
of such holder for the Exercise Price or as a shareholder of the Company,
whether such liability is asserted by the Company or by creditors of the
Company.

      7. Transfer, Exchange, and Replacement of Warrant.

      (a) Restriction on Transfer. This Warrant and the rights granted to the
holder hereof are transferable, in whole or in part, upon surrender of this
Warrant, together with a properly executed assignment in the form attached
hereto, at the office or agency of the Company referred to in Paragraph 7(e)
below, provided, however, that any transfer or assignment shall be subject to
the conditions set forth in Paragraph 7(f) hereof and to the applicable
provisions of the Securities Purchase Agreement. Until due presentment for
registration of transfer on the books of the Company, the Company may treat the
registered holder hereof as the owner and holder hereof for all purposes, and
the Company shall not be affected by any notice to the contrary. Notwithstanding
anything to the contrary contained herein, the registration rights described in
Paragraph 8 are assignable only in accordance with the provisions of that
certain Registration Rights Agreement, dated November 17, 2005, by and among the
Company and the other signatories thereto (the "Registration Rights Agreement").

      (b) Warrant Exchangeable for Different Denominations. This Warrant is
exchangeable, upon the surrender hereof by the holder hereof at the office or
agency of the Company referred to in Paragraph 7(e) below, for new Warrants of
like tenor representing in the aggregate the right to purchase the number of
shares of Common Stock which may be purchased hereunder, each of such new
Warrants to represent the right to purchase such number of shares as shall be
designated by the holder hereof at the time of such surrender.

      (c) Replacement of Warrant. Upon 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, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

      (d) Cancellation; Payment of Expenses. Upon the surrender of this Warrant
in connection with any transfer, exchange, or replacement as provided in this
Paragraph 7, this Warrant shall be promptly canceled by the Company. The Company
shall pay all taxes (other than securities transfer taxes) and all other
expenses (other than legal expenses, if any, incurred by the holder or
transferees) and charges payable in connection with the preparation, execution,
and delivery of Warrants pursuant to this Paragraph 7.

      (e) Register. The Company shall maintain, at its principal executive
offices (or such other office or agency of the Company as it may designate by
notice to the holder hereof), a register for this Warrant, in which the Company
shall record the name and address of the person in whose name this Warrant has
been issued, as well as the name and address of each transferee and each prior
owner of this Warrant.

      (f) Exercise or Transfer Without Registration. If, at the time of the
surrender of this Warrant in connection with any exercise, transfer, or exchange
of this Warrant, this Warrant (or, in the case of any exercise, the Warrant
Shares issuable hereunder), shall not be registered under the Securities Act of
1933, as amended (the "Securities Act") and under applicable state securities or
blue sky laws, the Company may require, as a condition of allowing such
exercise, transfer, or exchange, (i) that the holder or transferee of this
Warrant, as the case may be, furnish to the Company a written opinion of
counsel, which opinion and counsel are acceptable to the Company, to the effect
that such exercise, transfer, or exchange may be made without registration under
said Act and under applicable state securities or blue sky laws, (ii) that the
holder or transferee execute and deliver to the Company an investment letter in
form and substance acceptable to the Company and (iii) that the transferee be an
"accredited investor" as defined in Rule 501(a) promulgated under the Securities
Act; provided that no such opinion, letter or status as an "accredited investor"
shall be required in connection with a transfer pursuant to Rule 144 under the
Securities Act. The first holder of this Warrant, by taking and holding the
same, represents to the Company that such holder is acquiring this Warrant for
investment and not with a view to the distribution thereof.

      8. Registration Rights. The initial holder of this Warrant (and certain
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Warrant Shares as are set forth in Section 2 of the Registration
Rights Agreement.

permitted to be given or delivered hereunder to the holder of this Warrant shall

the Company, or at such other address as shall have been furnished to the
Company by notice from such holder. All notices, requests, and other

of the Company at 4699 Old Ironsides Drive, Suite 420, Santa Clara, CA 95054,
Attention: Chief Executive Officer, or at such other address as shall have been

notice, request, or other communication may be sent by facsimile, but shall in
such case be subsequently confirmed by a writing personally delivered or sent by
certified or registered mail or by recognized overnight mail courier as provided
above. All notices, requests, and other communications shall be deemed to have
been given either at the time of the receipt thereof by the person entitled to
receive such notice at the address of such person for purposes of this Paragraph
9, or, if mailed by registered or certified mail or with a recognized overnight
mail courier upon deposit with the United States Post Office or such overnight
mail courier, if postage is prepaid and the mailing is properly addressed, as
the case may be.

      10. Governing Law. THIS WARRANT SHALL BE ENFORCED, GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS. THE PARTIES HERETO HEREBY SUBMIT TO THE
EXCLUSIVE JURISDICTION OF THE UNITED STATES FEDERAL COURTS LOCATED IN NEW YORK,
NEW YORK WITH RESPECT TO ANY DISPUTE ARISING UNDER THIS WARRANT, THE AGREEMENTS
ENTERED INTO IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY. BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO
THE MAINTENANCE OF SUCH SUIT OR PROCEEDING. BOTH PARTIES FURTHER AGREE THAT
SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN
EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR
PROCEEDING. NOTHING HEREIN SHALL AFFECT EITHER PARTY'S RIGHT TO SERVE PROCESS IN
ANY OTHER MANNER PERMITTED BY LAW. BOTH PARTIES AGREE THAT A FINAL
NON-APPEALABLE JUDGMENT IN ANY SUCH SUIT OR PROCEEDING SHALL BE CONCLUSIVE AND
MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON SUCH JUDGMENT OR IN ANY OTHER
LAWFUL MANNER. THE PARTY WHICH DOES NOT PREVAIL IN ANY DISPUTE ARISING UNDER
THIS WARRANT SHALL BE RESPONSIBLE FOR ALL FEES AND EXPENSES, INCLUDING
ATTORNEYS' FEES, INCURRED BY THE PREVAILING PARTY IN CONNECTION WITH SUCH
DISPUTE.

      11. Miscellaneous.

      (a) Amendments. This Warrant and any provision hereof may only be amended
by an instrument in writing signed by the Company and the holder hereof.

      (b) Descriptive Headings. The descriptive headings of the several
paragraphs of this Warrant are inserted for purposes of reference only, and
shall not affect the meaning or construction of any of the provisions hereof.

      (c) Cashless Exercise. Notwithstanding anything to the contrary contained
in this Warrant, if the resale of the Warrant Shares by the holder is not then
registered pursuant to an effective registration statement under the Securities
Act, this Warrant may be exercised by

                                      -11-
<PAGE>

presentation and surrender of this Warrant to the Company at its principal
executive offices with a written notice of the holder's intention to effect a
cashless exercise, including a calculation of the number of shares of Common
Stock to be issued upon such exercise in accordance with the terms hereof (a
"Cashless Exercise"). In the event of a Cashless Exercise, in lieu of paying the
Exercise Price in cash, the holder shall surrender this Warrant for that number
of shares of Common Stock determined by multiplying the number of Warrant Shares
to which it would otherwise be entitled by a fraction, the numerator of which
shall be the difference between the then current Market Price per share of the
Common Stock and the Exercise Price, and the denominator of which shall be the
then current Market Price per share of Common Stock. For example, if the holder
is exercising 100,000 Warrants with a per Warrant exercise price of $0.75 per
share through a cashless exercise when the Common Stock's current Market Price
per share is $2.00 per share, then upon such Cashless Exercise the holder will
receive 62,500 shares of Common Stock.

      (d) Remedies. The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the holder, by vitiating
the intent and purpose of the transaction contemplated hereby. Accordingly, the
Company acknowledges that the remedy at law for a breach of its obligations
under this Warrant will be inadequate and agrees, in the event of a breach or
threatened breach by the Company of the provisions of this Warrant, that the
holder shall be entitled, in addition to all other available remedies at law or
in equity, and in addition to the penalties assessable herein, to an injunction
or injunctions restraining, preventing or curing any breach of this Warrant and
to enforce specifically the terms and provisions thereof, without the necessity
of showing economic loss and without any bond or other security being required.
