                          COMMON STOCK PURCHASE WARRANT

                TO PURCHASE __________ SHARES OF COMMON STOCK OF

                             INTERCHANGE CORPORATION

UNDER NASD RULE 2710(g) AND SUBJECT TO LIMITED EXCEPTIONS, THIS WARRANT AND THE
UNDERLYING SHARES OF COMMON STOCK SHALL NOT BE SOLD DURING THE INITIAL PUBLIC
OFFERING OF THE COMPANY'S COMMON STOCK (THE "PUBLIC OFFERING") OR SOLD,
TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED, OR BE THE SUBJECT OF ANY
HEDGING, SHORT SALE, DERIVATIVE, PUT, OR CALL TRANSACTION THAT WOULD RESULT IN
THE EFFECTIVE ECONOMIC DISPOSITION OF THIS WARRANT OR THE SECURITIES UNDERLYING
THIS WARRANT BY ANY PERSON FOR A PERIOD OF 180 DAYS IMMEDIATELY FOLLOWING THE
DATE OF EFFECTIVENESS OR COMMENCEMENT OF SALES OF THE PUBLIC OFFERING.

            THIS COMMON STOCK PURCHASE WARRANT certifies that, for value
received, Roth Capital Partners, LLC (the "Holder") is entitled, upon the terms
and subject to the limitations on exercise and the conditions hereinafter set
forth, at any time on or after October __, 2005 (the "Initial Exercise Date")
and on or prior to the close of business on October __, 2009 (the "Termination
Date") but not thereafter, to subscribe for and purchase from Interchange
Corporation, a corporation incorporated in the State of Delaware (the
"Company"), up to ________ shares of Common Stock, par value $0.00001 per share,
of the Company (the "Common Stock"). The purchase price of one share of Common
Stock (the "Exercise Price") under this Warrant shall be $________ [EQUAL TO
125% OF PUBLIC OFFERING PRICE], subject to adjustment hereunder. "Warrant" as
used herein shall include this common stock purchase warrant and any warrants
delivered in substitution or exchange therefor as provided herein.

            1. Title to Warrant. Prior to the Termination Date and subject to
the transfer restrictions imposed by NASD Rule 2710(g) as set forth in the above
legend, this Warrant and all rights hereunder are transferable, in whole or in
part, at the office or agency of the Company by the Holder in person or by duly
authorized attorney, upon surrender of this Warrant together with the Assignment
Form annexed hereto properly endorsed.

            2. Authorization of Shares. The Company covenants that all shares of
Common Stock (or other securities to which Holder is entitled pursuant to
Section 11 or Section 12 hereof) which may be issued upon the exercise of the
purchase rights represented by this Warrant (the "Warrant Shares") will, upon
exercise of the purchase rights represented by this Warrant, be duly authorized,
validly issued, fully paid and nonassessable and free from all taxes, liens and
charges in respect of the issue thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue).

            3. Exercise of Warrant.

                  (a) Except as provided in Section 4 herein, the purchase
      rights represented by this Warrant may be exercised in whole or in part,
      at any time, or from time to time, on or after the Initial Exercise Date
      and on or before the Termination Date by delivering this Warrant and the
      Notice of Exercise Form annexed hereto duly executed to the office of the
      Company (or such

                                       1
<PAGE>
      other office or agency of the Company as it may designate by notice in
      writing to the registered Holder at the address of such Holder appearing
      on the books of the Company) and by payment of the Exercise Price of the
      shares thereby purchased by wire transfer, cash or check. Warrant Shares
      purchased hereunder shall be delivered to the Holder within three (3)
      business days after the date on which this Warrant shall have been
      exercised as aforesaid. This Warrant shall be deemed to have been
      exercised and such certificate or certificates shall be deemed to have
      been issued, and the Holder or any other person so designated to be named
      therein shall be deemed to have become a holder of record of such shares
      for all purposes, as of the date the Warrant has been exercised by payment
      to the Company of the Exercise Price. If eligible, the Warrant Shares
      shall be delivered by the Company to the Holder via the Depository Trust
      Company's ("DTC") Deposit Withdrawal Agent Commission ("DWAC") system via
      the DTC instructions provided to the Company in the Notice of Exercise. If
      the Company fails to deliver the Warrant Shares to the Holder pursuant to
      this Section 3(a) by the close of business on the third (3rd) business day
      after the date of exercise, then the Holder will have the right to rescind
      such exercise. In addition to any other rights available to the Holder, if
      the Company fails to deliver to the Holder a certificate or certificates
      representing the Warrant Shares pursuant to an exercise by the close of
      business on the third (3rd) business day after the date of exercise, and
      if after such third (3rd) business day the Holder is required by its
      broker to purchase (in an open market transaction or otherwise) shares of
      Common Stock to deliver in satisfaction of a sale by the Holder of the
      Warrant Shares which the Holder anticipated receiving upon such exercise
      (a "Buy-In"), then the Company shall (i) pay in cash to the Holder the
      amount by which (A) the Holder's total purchase price (including brokerage
      commissions, if any) for the shares of Common Stock so purchased exceeds
      (B) the amount obtained by multiplying (x) the number of Warrant Shares
      that the Company was required to deliver to the Holder in connection with
      the exercise at issue times (y) the price at which the sell order giving
      rise to such purchase obligation was executed, and (ii) at the option of
      the Holder, either reinstate the portion of the Warrant and equivalent
      number of Warrant Shares for which such exercise was not honored or
      deliver to the Holder the number of shares of Common Stock that would have
      been issued had the Company timely complied with its exercise and delivery
      obligations hereunder. For example, under clause (i) of the immediately
      preceding sentence, if the Holder purchases Common Stock having a total
      purchase price of $11,000 to cover a Buy-In with respect to an attempted
      exercise of shares of Common Stock with an aggregate sale price giving
      rise to such purchase obligation of $10,000, the Company shall be required
      to pay the Holder $1,000. The Holder shall provide the Company written
      notice indicating the amounts payable to the Holder in respect of the
      Buy-In, together with applicable confirmations and other evidence
      reasonably requested by the Company. Nothing herein shall limit Holder's
      right to pursue any other remedies available to it hereunder, at law or in
      equity including, without limitation, a decree of specific performance
      and/or injunctive relief with respect to the Company's failure to timely
      deliver certificates representing shares of Common Stock upon exercise of
      the Warrant as required pursuant to the terms hereof.

                  (b) If this Warrant shall have been exercised in part, the
      Company shall, at the time of delivery of the certificate or certificates
      representing Warrant Shares, deliver to Holder a new Warrant evidencing
      the rights of Holder to purchase the unpurchased Warrant Shares called for
      by this Warrant, which new Warrant shall in all other respects be
      identical with this Warrant.

                                       2
<PAGE>

            4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

            5. Charges and Expenses. Issuance of certificates for Warrant Shares
shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder.

            6. Closing of Books. The Company will not close its stockholder
books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.

            7. Transfer, Division and Combination.

                  (a) Subject to the transfer restrictions imposed by NASD Rule
      2710(g) as set forth in the legend hereto, this Warrant and all rights
      hereunder are transferable, in whole or in part, upon surrender of this
      Warrant at the principal office of the Company, together with a written
      assignment of this Warrant substantially in the form attached hereto duly
      executed by the Holder or its agent or attorney. Upon such surrender, the
      Company shall execute and deliver a new Warrant or Warrants in the name of
      the assignee or assignees and in the denomination or denominations
      specified in such instrument of assignment, and shall issue to the
      assignor a new

                                       3
<PAGE>
      Warrant evidencing the portion of this Warrant not so assigned, and this
      Warrant shall promptly be cancelled. A Warrant, if properly assigned, may
      be exercised by a new holder for the purchase of Warrant Shares without
      having a new Warrant issued.

                  (b) Subject to the transfer restrictions imposed by NASD Rule
      2710(g) as set forth in the legend hereto, this Warrant may be divided or
      combined with other Warrants upon presentation hereof at the aforesaid
      office of the Company, together with a written notice specifying the names
      and denominations in which new Warrants are to be issued, signed by the
      Holder or its agent or attorney. Subject to compliance with Section 7(a),
      as to any transfer which may be involved in such division or combination,
      the Company shall execute and deliver a new Warrant or Warrants in
      exchange for the Warrant or Warrants to be divided or combined in
      accordance with such notice.

                  (c) The Company shall prepare, issue and deliver at its own
      expense the new Warrant or Warrants under this Section 7.

                  (d) The Company agrees to maintain, at its aforesaid office,
      books for the registration and the registration of transfer of the
      Warrants.

            8. No Rights as Shareholder until Exercise. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price (or by means of a cashless exercise),
the Warrant Shares so purchased shall be and be deemed to be issued to such
Holder as the record owner of such shares as of the close of business on the
later of the date of such surrender or payment.

            9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

            10. Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday on which banks in the
United States are closed, then such action may be taken or such right may be
exercised on the next succeeding day which is not a Saturday, Sunday or legal
holiday.

            11. Adjustments of Exercise Price and Number of Warrant Shares;
Stock Splits, Etc. The number and kind of securities purchasable upon the
exercise of this Warrant and the Exercise Price shall be subject to adjustment
from time to time upon the happening of any of the following. In case the
Company shall (a) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (b) subdivide its outstanding shares of Common Stock into a greater
number of shares, (c) combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock, or (d) issue any shares of its capital
stock in a reclassification of the Common Stock, then the number of Warrant
Shares purchasable upon exercise of this Warrant immediately prior thereto shall
be adjusted so that the Holder shall be entitled to receive the kind and number
of Warrant Shares or other securities of the Company which it would have owned
or have been entitled to receive had such Warrant been exercised in advance
thereof. Upon each such adjustment of the kind and number of Warrant Shares or
other securities of the Company which are

                                       4
<PAGE>
purchasable hereunder, the Holder shall thereafter be entitled to purchase the
number of Warrant Shares or other securities resulting from such adjustment at
an Exercise Price per Warrant Share or other security obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of Warrant Shares purchasable pursuant hereto immediately prior to such
adjustment and dividing by the number of Warrant Shares or other securities of
the Company resulting from such adjustment. An adjustment made pursuant to this
paragraph shall become effective immediately after the effective date of such
event retroactive to the record date, if any, for such event.

            12. Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another entity
(where the Company is not the surviving entity or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer
or otherwise dispose of all or substantially all its property, assets or
business to another entity and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation or disposition of assets, shares of
common stock of the successor or acquiring entity, or any cash, shares of stock
or other securities or property of any nature whatsoever (including warrants or
other subscription or purchase rights) in addition to or in lieu of common stock
of the successor or acquiring entity ("Other Property"), are to be received by
or distributed to the holders of Common Stock of the Company, then the Holder
shall have the right thereafter to receive, upon exercise of this Warrant,
instead of the shares of Common Stock, the number of shares of common stock
and/or Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by Holder of
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring entity (if other than the Company) shall expressly assume the due
and punctual observance and performance of each and every covenant and condition
of this Warrant to be performed and observed by the Company and all the
obligations and liabilities hereunder, subject to such modifications as may be
deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of Warrant Shares
for which this Warrant is exercisable which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 12. For purposes of
this Section 12, "common stock" of a corporation shall include stock of such
corporation of any class which is not preferred as to dividends or assets over
any other class of stock of such corporation and which is not subject to
redemption and shall also include any evidences of indebtedness, shares of stock
or other securities which are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event and any warrants or other rights to subscribe for
or purchase any such stock. The foregoing provisions of this Section 12 shall
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

            13. 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.

            14. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall give notice thereof to the Holder, which notice shall state the number of
Warrant Shares (and/or other securities or property) purchasable upon the
exercise of this Warrant and the Exercise Price of such Warrant Shares (and/or
other securities or property) after such adjustment, setting forth a brief
statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made.

            15. Notice of Corporate Action. If at any time:

                                       5
<PAGE>
                  (a) the Company shall take a record of the holders of its
      Common Stock for the purpose of entitling them to receive an extraordinary
      dividend or other distribution, or any right to subscribe for or purchase
      any evidences of its indebtedness, any shares of stock of any class or any
      other securities or property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Common
      Stock, any reclassification or recapitalization of the capital stock of
      the Company or any consolidation or merger of the Company with, or any
      sale, transfer or other disposition of all or substantially all the
      property, assets or business of the Company to, another entity, or

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

                  (d) the loss of effectiveness or availability for use of the
      Registration Statement, as reasonably determined by the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 10 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 10
days' prior written notice of the date when the same shall take place, and (iii)
in the case of the loss of effectiveness or availability for use of the
Registration Statement, promptly upon knowledge by the Company of such
occurrence. Such notice in accordance with the foregoing clauses (a)-(c) also
shall specify (i) the date on which any such record is to be taken for the
purpose of such dividend, distribution or right, the date on which the holders
of Common Stock shall be entitled to any such dividend, distribution or right,
and the amount and character thereof, and (ii) the date on which any such
reorganization, reclassification, merger, consolidation, sale, transfer,
disposition, dissolution, liquidation or winding up is to take place and the
time, if any such time is to be fixed, as of which the holders of Common Stock
shall be entitled to exchange their Warrant Shares for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Such notice in accordance with clause (d) shall also specify the Company's
good faith belief as to when a registration statement registering such sale
shall be filed or amended or available for use again. Each such written notice
shall be sufficiently given if addressed to Holder at the last address of Holder
appearing on the books of the Company and delivered in accordance with Section
18(e).

            16. Authorized Shares; No Impairment; Authorizations. The Company
covenants that during the period the Warrant is outstanding, it will reserve
from its authorized and unissued Common Stock a sufficient number of shares to
provide for the issuance of the Warrant Shares upon the exercise of any purchase
rights under this Warrant. The Company further covenants that its issuance of
this Warrant shall constitute full authority to its officers who are charged
with the duty of executing stock certificates to execute and issue the necessary
certificates for the Warrant Shares upon the exercise of the purchase rights
under this Warrant. The Company will take all such reasonable action as may be
necessary to assure that such Warrant Shares may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of
the principal market or exchange upon which the Common Stock may be listed.

            Except and to the extent as waived or consented to by the Holder,
the Company shall not by any action, including, without limitation, amending its
certificate of incorporation 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 of this

                                       6
<PAGE>
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such actions as may be necessary or
appropriate to protect the rights of Holder as set forth in this Warrant against
impairment. Without limiting the generality of the foregoing, the Company will
(a) not increase the par value of any Warrant Shares above the amount payable
therefor upon such exercise immediately prior to such increase in par value, (b)
take all such action as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable Warrant
Shares upon the exercise of this Warrant, and (c) use commercially reasonable
efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be necessary to enable
the Company to perform its obligations under this Warrant.

            Before taking any action which would result in an adjustment in the
number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

            17. Registration Rights.

                  (a) At any time on or after the Initial Exercise Date, Holder
      shall have the right to request that the Company file with the Securities
      and Exchange Commission a registration statement covering the resale of
      the Warrant Shares for an offering to be made on a continuous basis
      pursuant to Rule 415 or registering the sale of the Warrant Shares to the
      Holder upon exercise of this Warrant (the "Registration Statement");
      provided, however, the Company shall not have any obligation to file a
      Registration Statement if, at such time, all of the Warrant Shares could
      be sold by Holder without volume restrictions pursuant to Rule 144(k)
      promulgated under the Securities Act of 1933, as amended (the "Securities
      Act"), as determined by legal counsel reasonably acceptable to Holder
      pursuant to a written opinion to such effect addressed and acceptable to
      the Company's transfer agent. Upon such request, Company shall file within
      thirty (30) days of such request (the "Filing Deadline") the Registration
      Statement required hereunder and shall use its best efforts to effect as
      soon as practicable, and in any event within ninety (90) days of the
      receipt of such request, the registration under the Securities Act of all
      of the Warrant Shares. The Company shall pay all costs and expenses
      related to the registration of the Warrant Shares. The Company shall use
      its best efforts to keep such Registration Statement continuously
      effective under the Securities Act, until all Warrant Shares covered by
      such Registration Statement have been sold or may be sold without volume
      restrictions pursuant to Rule 144(k), as determined by legal counsel
      reasonably acceptable to Holder pursuant to a written opinion to such
      effect addressed and acceptable to the Company's transfer agent.

                  (b) If the Registration Statement is not filed with the SEC on
      or before the Filing Deadline or, in the event the Registration Statement
      is reviewed by the SEC, if the Company does not submit written responses
      to the SEC within ten (10) business days after receipt of comments to the
      Registration Statement from the SEC (thirty (30) calendar days in the
      event the SEC requires material changes to or a restatement of the
      Company's financial statements), the Company shall pay to Holder an amount
      equal to the product of (i) the Exercise Price multiplied by (ii) 2.0% for
      each 30-day period (or pro rata portion thereof) after the Filing Deadline
      and prior to the date the Registration Statement is filed with the SEC or
      after the ten (10) business day (or thirty (30) calendar days as
      applicable) period after the Company receives the SEC's comments to the
      Registration Statement and prior to the date the Company submits written
      responses to such comments, as the case may be.

                  (c) The Company shall, not less than three (3) business days
      prior to the filing of the Registration Statement or any related
      prospectus or any amendment or supplement

                                       7
<PAGE>
      thereto, (i) furnish to Holder copies of the Registration Statement or
      prospectus proposed to be filed, which documents will be subject to the
      review of such Holder, and (ii) cause its officers and directors, counsel
      and independent certified public accountants to respond to such inquiries
      as shall be necessary, in the reasonable opinion of respective counsel to
      conduct a reasonable investigation within the meaning of the Securities
      Act. Furthermore, the Company shall advise Holder, within two (2) business
      days: (x) after it shall receive notice or obtain knowledge of the
      issuance of any stop order by the SEC delaying or suspending the
      effectiveness of the Registration Statement or of the initiation or threat
      of any proceeding for that purpose, or any other order issued by any state
      securities commission or other regulatory authority suspending the
      qualification or exemption from qualification of such Warrant Shares under
      state securities or "blue sky" laws; and it will promptly use its best
      efforts to prevent the issuance of any stop order or other order or to
      obtain its withdrawal at the earliest possible moment if such stop order
      or other order should be issued; and (y) when the prospectus or any
      prospectus supplement or post-effective amendment has been filed, and,
      with respect to the Registration Statement or any post-effective amendment
      thereto, when the same has become effective.

                  (d) In addition, Holder shall be entitled to unlimited
      "piggyback" registration rights such that if the Company proposes to
      register (including for this purpose a registration effected by the
      Company for security holders other than Holder) any of its stock or other
      securities under the Securities Act in connection with the public offering
      of such securities solely for cash (other than a registration relating
      solely to the sale of securities to participants in a Company stock plan,
      a registration on any form which does not include substantially the same
      information as would be required to be included in a registration
      statement covering the sale of the Warrant Shares), the Company shall, at
      such time, promptly give Holder written notice (the "Company's Notice") of
      such registration. Upon the written request of Holder given within twenty
      (20) days of the Company's Notice, the Company shall cause to be
      registered under the Act all of the Warrant Shares that such Holder has
      requested to be registered; provided, however, if such public offering is
      to be underwritten and, in the good faith judgment of the managing
      underwriter, the inclusion of all of the Warrant Shares that such Holder
      has requested to be registered would interfere with the successful
      marketing of a smaller number of such shares of the Company's stock or
      other securities, the number of Warrant Shares to be included in such
      public offering shall be reduced as determined in the good faith judgment
      of such managing underwriter; provided further that the managing
      underwriter shall reduce, limit or exclude securities for registration in
      the following order: (i) first, among securities requested to be included
      in such registration by any person who does not have a contractual right
      to request registration of such securities; (ii) second, pro rata among
      the securities requested to be included in such registration by persons
      with a right to request registration of such securities, on the basis of
      the number of securities owned by such holders requesting inclusion in the
      registration; and (iii) third, among the securities which the Company
      proposes to sell. Upon request by the managing underwriter of such
      offering, any Warrant Shares that are thereby excluded from the offering
      shall be withheld from the market by the Holder for a period (not to
      exceed 30 days prior to the effective date and 90 days thereafter) that
      the managing underwriter reasonably determines is necessary in order to
      successfully complete the underwritten public offering; provided, however,
      that the foregoing restrictions shall not apply to Holder unless all
      officers and directors of the Company and all holders of one percent or
      more of the Company's outstanding capital stock and all holders with
      registration rights of any kind are bound by similar agreements or
      restrictions.

                  (e) (i) The Company agrees to indemnify and hold harmless each
      Selling Stockholder (as defined below) from and against any losses,
      claims, damages, liabilities or expenses to which such Selling Stockholder
      may become subject (under the Securities Act or otherwise) insofar as such
      losses, claims, damages, liabilities or expenses (or actions or

                                       8
<PAGE>
      proceedings in respect thereof) arise out of, or are based upon (A) any
      untrue statement of a material fact contained in the Registration
      Statement or prospectus, (B) any failure by the Company to fulfill any
      undertaking included in the Registration Statement, (C) any breach of any
      representation, warranty or covenant made by the Company in this Warrant
      and (D) any violation or alleged violation of the Securities Act, the
      Securities Exchange Act of 1934, as amended (the "Exchange Act"), any
      other law, including, without limitation, any state securities law, or any
      rule or regulation thereunder relating to the offer or sale of the Warrant
      Shares (but excluding claims arising from a failure of the Holder to
      deliver the prospectus in compliance with applicable securities laws,
      where such failure to deliver was the cause of such claim or would have
      corrected the alleged damage), and the Company will promptly reimburse
      such Selling Stockholder for any reasonable legal or other expenses
      incurred in investigating, defending or preparing to defend, settling,
      compromising or paying any such action, proceeding or claim, provided,
      however, that the Company shall not be liable in any such case to the
      extent that such loss, claim, damage, liability or expense arises solely
      out of, or is based solely upon, an untrue statement made in such
      Registration Statement in reliance upon and in conformity with written
      information furnished to the Company by such Selling Stockholder
      specifically for use in preparation of the Registration Statement.

                        (ii) The Holder agrees (severally and not jointly with
      any other Holder) to indemnify and hold harmless the Company (and each
      person, if any, who controls the Company within the meaning of Section 15
      of the Securities Act, each officer of the Company who signs the
      Registration Statement and each director of the Company) from and against
      any losses, claims, damages, liabilities or expenses to which the Company
      (or any such officer, director or controlling person) may become subject
      (under the Securities Act or otherwise), insofar as such losses, claims,
      damages, liabilities or expenses (or actions or proceedings in respect
      thereof) arise solely out of, or are based solely upon, (A) any untrue
      statement of a material fact contained in the Registration Statement, but
      only if and to the extent that such untrue statement was made in reliance
      upon and in conformity with written information furnished by the Holder
      specifically for use in preparation of the Registration Statement
      (provided, however, that the Holder shall not be liable in any such case
      for any untrue statement in any Registration Statement or prospectus if
      such statement has been corrected in writing by such Holder and delivered
      to the Company at least three business days prior to the pertinent sale or
      sales by the Holder) or (B) any violation or alleged violation of the
      Securities Act, the Exchange Act, any other law, including, without
      limitation, any state securities law, or any rule or regulation thereunder
      relating to the offer or sale of the Warrant Shares by Holder, and the
      Holder will reimburse the Company (or such officer, director or
      controlling person), as the case may be, for any legal or other expenses
      reasonably incurred in investigating, defending or preparing to defend,
      settling, compromising or paying any such action, proceeding or claim.
      Notwithstanding the foregoing, the Holder's aggregate liability pursuant
      to this subsection (ii) shall be limited to the net amount received by the
      Holder from the sale of the Warrant Shares.

                        (iii) Promptly after receipt by any indemnified person
      of a notice of a claim or the beginning of any action in respect of which
      indemnity is to be sought against an indemnifying person pursuant to this
      Section 17(e), such indemnified person shall notify the indemnifying
      person in writing of such claim or of the commencement of such action, but
      the omission to so notify the indemnifying party will not relieve it from
      any liability which it may have to any indemnified party under this
      Section 17(e) (except to the extent that such omission materially and
      adversely affects the indemnifying party's ability to defend such action)
      or from any liability otherwise than under this Section 17(e). Subject to
      the provisions hereinafter stated, in case any such action shall be
      brought against an indemnified person, the indemnifying person shall be
      entitled to participate therein, and, to the extent that it shall elect by
      written notice

                                       9
<PAGE>
      delivered to the indemnified party promptly after receiving the aforesaid
      notice from such indemnified party, shall be entitled to assume the
      defense thereof, with counsel reasonably satisfactory to such indemnified
      person. After notice from the indemnifying person to such indemnified
      person of its election to assume the defense thereof, such indemnifying
      person shall not be liable to such indemnified person for any legal
      expenses subsequently incurred by such indemnified person in connection
      with the defense thereof, provided further, however, that if there exists
      or shall exist a conflict of interest that would make it inappropriate, in
      the opinion of counsel to the indemnifying person, for the same counsel to
      represent both the indemnified person and such indemnifying person or any
      affiliate or associate thereof, the indemnified person shall be entitled
      to retain its own counsel at the expense of such indemnifying person;
      provided, however, that no indemnifying person shall be responsible for
      the fees and expenses of more than one separate counsel (together with
      appropriate local counsel) for all indemnified parties. In no event shall
      any indemnifying person be liable in respect of any amounts paid in
      settlement of any action unless the indemnifying person shall have
      approved the terms of such settlement; provided that such consent shall
      not be unreasonably withheld. No indemnifying person shall, without the
      prior written consent of the indemnified person, effect any settlement of
      any pending or threatened proceeding in respect of which any indemnified
      person is or could have been a party and indemnification could have been
      sought hereunder by such indemnified person, unless such settlement
      includes an unconditional release of such indemnified person from all
      liability on claims that are the subject matter of such proceeding.

                        (iv) If the indemnification provided for in this Section
      17(e) is unavailable to or insufficient to hold harmless an indemnified
      party under subsection (A) or (B) above in respect of any losses, claims,
      damages, liabilities or expenses (or actions or proceedings in respect
      thereof) referred to therein, then each indemnifying party shall
      contribute to the amount paid or payable by such indemnified party as a
      result of such losses, claims, damages, liabilities or expenses (or
      actions in respect thereof) in such proportion as is appropriate to
      reflect the relative fault of the Company on the one hand and the Holder
      on the other in connection with the statements or omissions or other
      matters which resulted in such losses, claims, damages, liabilities or
      expenses (or actions in respect thereof), as well as any other relevant
      equitable considerations. The relative fault shall be determined by
      reference to, among other things, in the case of an untrue statement,
      whether the untrue statement relates to information supplied by the
      Company on the one hand or the Holder on the other and the parties'
      relative intent, knowledge, access to information and opportunity to
      correct or prevent such untrue statement. The Company and the Holders
      agree that it would not be just and equitable if contribution pursuant to
      this subsection (iv) were determined by pro rata allocation (even if the
      Holders were treated as one entity for such purpose) or by any other
      method of allocation which does not take into account the equitable
      considerations referred to above in this subsection (iv). The amount paid
      or payable by an indemnified party as a result of the losses, claims,
      damages or liabilities (or actions in respect thereof) referred to above
      in this subsection (iv) shall be deemed to include any legal or other
      expenses reasonably incurred by such indemnified party in connection with
      investigating or defending any such action or claim. Notwithstanding the
      provisions of this subsection (iv), Holder shall not be required to
      contribute any amount in excess of the net amount received by the Holder
      from the sale of the Warrant Shares. No person guilty of fraudulent
      misrepresentation (within the meaning of Section 11(f) of the Securities
      Act) shall be entitled to contribution from any person who was not guilty
      of such fraudulent misrepresentation. The Holders' obligations in this
      subsection to contribute are several in proportion to their sales of
      Warrant Shares to which such loss relates and not joint.

                        (v) For purposes of this Section 17(e), the term
      "Selling Stockholder" shall include the Holder, its officers, directors,
      employees, partners, agents and any

                                       10
<PAGE>
      person controlling such Holder; the term "Registration Statement" shall
      include any final prospectus, exhibit, supplement or amendment included in
      or relating to the Registration Statement; and the term "untrue statement"
      shall include (A) any untrue statement or alleged untrue statement, or any
      omission or alleged omission to state in the Registration Statement a
      material fact required to be stated therein or necessary to make the
      statements therein not misleading and (B) any untrue statement or alleged
      untrue statement, or any omission or alleged omission to state in the
      prospectus a material fact required to be stated therein or necessary to
      make the statements therein, in the light of the circumstances under which
      they were made, not misleading.

            18. Miscellaneous.

                  (a) Jurisdiction. This Warrant shall be governed by and
      construed in accordance with the laws of the state of New York as applied
      to contracts among New York residents made and to be performed entirely
      within the state of New York, without regard to its conflict of law
      principles or rules.

                  (b) Restrictions. The Holder acknowledges that the Warrant
      Shares acquired upon the exercise of this Warrant, if not registered, will
      have restrictions upon resale imposed by state and federal securities
      laws.

                  (c) Nonwaiver and Expenses. No course of dealing or any delay
      or failure to exercise any right hereunder on the part of Holder shall
      operate as a waiver of such right or otherwise prejudice Holder's rights,
      powers or remedies, notwithstanding all rights hereunder terminate on the
      Termination Date. If the Company willfully and knowingly fails to comply
      with any provision of this Warrant, which results in any material damages
      to the Holder, the Company shall pay to Holder such amounts as shall be
      sufficient to cover any costs and expenses including, but not limited to,
      reasonable attorneys' fees, including those of appellate proceedings,
      incurred by Holder in collecting any amounts due pursuant hereto or in
      otherwise enforcing any of its rights, powers or remedies hereunder.

                  (d) NASD Rules. Notwithstanding anything contained in this
      Warrant, the terms of this Warrant are intended to comply with the rules
      and regulations of the National Association of Securities Dealers, Inc.
      relating to the compensation of underwriters and placement agents, and any
      provision of this Warrant that is determined to be inconsistent with such
      rules shall be deemed to be modified to the extent necessary to comply
      with such rules.

                  (e) Notices. Except as otherwise provided herein, any notice
      or request required or permitted to be given or delivered to the Holder by
      the Company shall be given in writing and shall be deemed effectively
      given (i) upon personal delivery to Holder, (ii) when sent by electronic
      mail or confirmed facsimile if sent during normal business hours of
      Holder, and if not sent during normal business hours, then on the next
      business day, (iii) five (5) days after having been sent by registered or
      certified mail, return receipt requested, postage prepaid, or (iv) one (1)
      day after deposit with a nationally recognized overnight courier,
      specifying next day delivery, with written verification of receipt. All
      such notices or requests shall be sent to: ATTN: ___________, Roth Capital
      Partners, LLC, 24 Corporate Plaza, Newport Beach, CA 92660, Facsimile No.
      (949) 720-7223.

                  (f) Limitation of Liability. No provision hereof, in the
      absence of any affirmative action by Holder to exercise this Warrant or
      purchase Warrant Shares, and no enumeration herein of the rights or
      privileges of Holder, shall give rise to any liability of Holder

                                       11
<PAGE>
      for the purchase price of any Common Stock or as a stockholder of the
      Company, whether such liability is asserted by the Company or by creditors
      of the Company.

                  (g) Remedies. Holder, in addition to being entitled to
      exercise all rights granted by law, including recovery of damages, will be
      entitled to specific performance of its rights under this Warrant. The
      Company agrees that monetary damages would not be adequate compensation
      for any loss incurred by reason of a breach by it of the provisions of
      this Warrant and hereby agrees to waive the defense in any action for
      specific performance that a remedy at law would be adequate.

                  (h) Successors and Assigns. Subject to applicable securities
      laws, this Warrant and the rights and obligations evidenced hereby shall
      inure to the benefit of and be binding upon the successors of the Company
      and the successors and permitted assigns of Holder. The provisions of this
      Warrant are intended to be for the benefit of all Holders from time to
      time of this Warrant and shall be enforceable by any such Holder or holder
      of Warrant Shares.

                  (i) Amendment. This Warrant may be modified or amended or the
      provisions hereof waived with the written consent of the Company and the
      Holder; provided, however, if this Warrant is subsequently transferred to
      other Persons, this Warrant may be modified or amended or the provisions
      hereof waived with the written consent of such transferees (and the
      original Holder if such Holder holds any part of the Warrant at such time)
      holding Warrant(s) exercisable into a majority of the Warrant Shares then
      issuable under the Warrants derived from the initial Warrant.

                  (j) Severability. Wherever possible, each provision of this
      Warrant shall be interpreted in such manner as to be effective and valid
      under applicable law, but if any provision of this Warrant shall be
      prohibited by or invalid under applicable law, such provision shall be
      ineffective to the extent of such prohibition or invalidity, without
      invalidating the remainder of such provisions or the remaining provisions
      of this Warrant.

                  (k) Headings. The headings used in this Warrant are for the
      convenience of reference only and shall not, for any purpose, be deemed a
      part of this Warrant.
