note to attached: 

Representative’s
Option for the Purchase of Common Stock

The Representative is a co-managing
underwriter pursuant to an Underwriting Agreement dated ____________, 2005 (“Underwriting
Agreement”) with A4S Technologies, Inc. (“A4S”) relating to the offering
of 1,200,000 Units of A4S. Each Unit consists of one share of A4S’s common stock and
one warrant to purchase common stock, all as more fully described in the Underwriting
Agreement and in a Warrant Agreement dated ______________________, 2005 between
A4S and Corporate Stock Transfer, as warrant agent.  

The Units will be traded on the
_______ until such time as A4S has (i) delivered a Notice of Separation to holders of
Units and the warrant agent advising that the Units can be detached and separated into
common stock and warrants; and (ii) provided for the separate listing of such common
shares and warrants on the _____. Each Unit will be divided into its separate component
of one share of common stock and one warrant upon the earlier of ninety (90) days from
the date of the Prospectus, or thirty (30) days after the Underwriters have fully
exercised their over-allotment option. Since the underwriters’ options and warrants
are not exercisable for 180 days from the date of issuance, the attached Representative’s
Options assume that the Units have been separated into their separate component parts of
common stock and warrants.

	___________ Representative’s Options

THIS CERTIFIES that, for receipt in
hand of $90 and other value received, NEWBRIDGE SECURITIES CORPORATION (the
“Holder”), is entitled to subscribe for and purchase from A4S TECHNOLOGIES,
INC., a Colorado corporation (the “Company”), upon the terms and conditions set
forth herein, at any time, or from time to time, after ____________________ , 2005 and
before 5:00 p.m. Colorado time on ____________________ , 2010 (the “Exercise
Period”), ____________________ shares of Common Stock (the “Option
Shares”), at a price of $ ____________________ per Option Share (the “Exercise
Price”), or 120% of the assumed $ ____________ offering price per share of the
Common Stock included in the Units to be sold by the Company in a public offering under
Registration Statement Form SB-1, No. 333-____ (the “Public Offering”) at or
prior to the date hereof. 

        The
term the “Holder” as used herein shall include any transferee to whom this
Representative’s Option has been transferred in accordance with the terms of this
Representative’s Option. As used herein the term “this Representative’s
Option” shall mean and include this Representative’s Option and any
Representative’s Option or Representative’s Options hereafter issued as a
consequence of the exercise or transfer of this Representative’s Option in whole or
in part, and the term “Common Stock” shall mean and include the Company’s
Common Stock with ordinary voting power, which class at the date hereof is publicly
traded. 

            1.       
          (a) This Representative’s Option may not be sold, transferred, assigned,
          pledged or hypothecated until ____________________ , 2005 (180 days after the
          effective date of the registration statement on which it is initially
          registered) except that it may be transferred, in whole or in part, (i) to one
          or more officers or partners of the Holder (or the officers or partners of any
          such partner); (ii) to a member of the underwriting syndicate and/or its
          officers or partners; (iii) by reason of reorganization of the Company; or (iv)
          by operation of law. After ____________________ , 2005, this
          Representative’s Option may be sold, transferred, assigned or hypothecated
          in accordance with applicable law. 

A4S Representatives' Share Option 

This Representative’s Option may
be exercised during the Exercise Period as to the whole or any lesser number of Option
Shares, by the surrender of this Representative’s Option (with the election attached
hereto duly executed) to the Company at its office at 489 N. Denver Avenue, Loveland, CO
80537, or such other place as is designated in writing by the Company, together with a
certified or bank cashier’s check payable to the order of the Company in an amount
equal to the Exercise Price multiplied by the number of Option Shares for which this
Representative’s Option is being exercised. 

            (b)       
          Upon written request of the Holder, and in lieu of payment for the Option Shares
          by check in accordance with paragraph 2(a) hereof, the Holder may exercise the
          Representative’s Option (or any portion thereof) for and receive the number
          of Option Shares equal to a fraction, the numerator of which equals (i) the
          amount by which the average of the Current Market Price of the Common Stock for
          the three days preceding the date of exercise exceeds the Exercise Price per
          Share, multiplied by (ii) the number of Option Shares to be purchased; the
          denominator of which equals the Current Market Price. 

            (c)       
          For the purposes of any computation under this Representative’s Option, the
          “Current Market Price” at any date shall be the closing price of the
          Common Stock on the business day next preceding the event requiring an
          adjustment hereunder. If the principal trading market for such securities is an
          exchange, the closing price shall be the reported last sale price on such
          exchange on such day provided if trading of such Common Stock is listed on any
          consolidated tape, the closing price shall be the reported last sale price set
          forth on such consolidated tape. If the principal trading market for such
          securities is the over-the-counter market, the closing price shall be the last
          reported sale price on such date as set forth by The Nasdaq Stock Market, Inc.,
          or, if the security is not quoted on such market, the average closing bid and
          asked prices as set forth in the National Quotation Bureau pink sheet or the
          Electronic Bulletin Board System for such day. Notwithstanding the foregoing, if
          there is no reported last sale price or average closing bid and asked prices, as
          the case may be, on a date prior to the event requiring an adjustment hereunder,
          then the current market price shall be determined as of the latest date prior to
          such day for which such last sale price or average closing bid and asked price
          is available. 

            3.       
          Upon each exercise of this Representative’s Option, the Holder shall be
          deemed to be the holder of record of the Option Shares issuable upon such
          exercise, notwithstanding that the transfer books of the Company shall then be
          closed or certificates representing such Option Shares shall not then have been
          actually delivered to the Holder. As soon as practicable after each such
          exercise of this Representative’s Option, the Company shall issue and
          deliver to the Holder a certificate or certificates for the Option Shares
          issuable upon such exercise, registered in the name of the Holder or its
          designee. If this Representative’s Option should be exercised in part only,
          the Company shall, upon surrender of this Representative’s Option for
          cancellation, execute and deliver a new Representative’s Option evidencing
          the right of the Holder to purchase the balance of the Option Shares (or
          portions thereof) subject to purchase hereunder. 

            4.       
          The Representative’s Option shall be registered in a Representative’s
          Option Register as they are issued. The Company shall be entitled to treat the
          registered holder of any Representative’s Option on the
          Representative’s Option Register as the owner in fact thereof for all
          purposes and shall not be bound to recognize any equitable or other claim to or
          interest in such Representative’s Option on the part of any other person.
          The Representative’s Option shall be transferable only on the books of the
          Company upon delivery thereof duly endorsed by the Holder or by his duly
          authorized attorney or representative, or accompanied by proper evidence of
          succession, assignment or authority to transfer. In all cases of transfer by an
          attorney, executor, administrator, guardian or other legal representative, duly
          authenticated evidence of his or its authority shall be produced. Upon any
          registration of transfer, the Company shall deliver a new Representative’s
          Option or Representative’s Options to the person entitled thereto. The
          Representative’s Option may be exchanged, at the option of the Holder
          thereof, for another Representative’s Option, or other
          Representative’s Option of different denominations, of like tenor and
          representing in the aggregate the right to purchase a like number of Option
          Shares (or portions thereof) upon surrender to the Company or its duly
          authorized agent. Notwithstanding the foregoing, the Company shall have no
          obligation to cause Representative’s Option to be transferred on its books
          to any person if, in the opinion of counsel to the Company, such transfer does
          not comply with the provisions of the Securities Act of 1933, as amended (the
          “Act”), or applicable state blue sky laws and the rules and
          regulations thereunder. 

-2- 

           5.       
          The Company shall at all times reserve and keep available out of its authorized
          and unissued Common Stock, solely for the purpose of providing for the exercise
          of this Representative’s Option, such number of shares of Common Stock as
          shall, from time to time, be sufficient therefor. The Company covenants that all
          Option Shares issuable upon exercise of this Representative’s Option shall
          be validly issued, fully paid, nonassessable, and free of preemptive rights. 

           (a)       
          If the Company shall at any time subdivide its outstanding Common Stock by
          recapitalization, reclassification or split-up thereof, the number of Option
          Shares subject to this Representative’s Option immediately prior to such
          subdivision shall be proportionately increased, and if the Company shall at any
          time combine the outstanding Common Stock by recapitalization, reclassification
          or combination thereof, the number of Option Shares subject to this
          Representative’s Option immediately prior to such combination shall be
          proportionately decreased. Any corresponding adjustment to the Exercise Price
          shall become effective at the close of business on the record date for such
          subdivision or combination. 

           (b)       
          If the Company after the date hereof shall distribute to the holders of its
          Common Stock any securities or other assets (other than a distribution of Common
          Stock or a cash distribution made as a dividend payable out of earnings or out
          of any earned surplus legally available for dividends under the laws of the
          jurisdiction of incorporation of the Company), the Board of Directors shall be
          required to make such equitable adjustment in the Exercise Price in effect
          immediately prior to the record date of such distribution as may be necessary to
          preserve the rights substantially proportionate to those enjoyed hereunder by
          the Holder immediately prior to such distribution. Any such adjustment made in
          good faith by the Board of Directors shall be final and binding upon the Holder
          and shall become effective as of the record date for such distribution. 

           (c)       
          No adjustment in the number of Option Shares subject to this
          Representative’s Option shall be required unless such adjustment would
          require an increase or decrease in such number of Option Shares of at least 1%
          of the then adjusted number of Option Shares issuable upon exercise of this
          Representative’s Option, provided, however, that any adjustments which by
          reason of the foregoing are not required at the time to be made shall be carried
          forward and taken into account and included in determining the amount of any
          subsequent adjustment; and provided further, however, that in case the Company
          shall at any time subdivide or combine the outstanding Common Stock or issue any
          additional Common Stock as a dividend, said percentage shall forthwith be
          proportionately increased in the case of a combination or decreased in the case
          of a subdivision or dividend of Common Stock so as to appropriately reflect the
          same. If the Company shall make a record of the holders of its Common Stock for
          the purpose of entitling them to receive any dividend or distribution and
          legally abandon its plan to pay or deliver such dividend or distribution then no
          adjustment in the number of Option Shares subject to this Representative’s
          Option shall be required by reason of the making of such record. 

           (d)       
          Whenever the number of Option Shares purchasable upon the exercise of this
          Representative’s Option is adjusted as provided herein, the Exercise Price
          shall be adjusted (to the nearest one tenth of a cent) by respectively
          multiplying such Exercise Price immediately prior to such adjustment by a
          fraction, the numerator of which shall be the number of Option Shares
          purchasable upon the exercise of this Representative’s Option immediately
          prior to such adjustment, and the denominator of which shall be the number of
          Option Shares purchasable immediately thereafter. 

           (e)       
          In case of any reclassification of the outstanding Common Stock (other than a
          change covered by (a) hereof or which solely affects the par value of such
          Common Stock) or in the case of any merger or consolidation of the Company with
          or into another corporation (other than a consolidation or merger in which the
          Company is the continuing corporation and which does not result in any
          reclassification or capital reorganization of the outstanding Common Stock), or
          in the case of any sale or conveyance to another corporation of the property of
          the Company as an entirety or substantially as an entirety in connection with
          which the Company is dissolved, the Holder of this Representative’s Option
          shall have the right thereafter (until the expiration of the right of exercise
          of this Representative’s Option) to receive upon the exercise hereof, for
          the same aggregate Exercise Price payable hereunder immediately prior to such
          event, the kind and amount of shares of stock or other securities or property
          receivable upon such reclassification, capital reorganization, merger or
          consolidation, or upon the dissolution following any sale or other transfer, by
          a holder of the number of Option Shares obtainable upon the exercise of this
          Representative’s Option immediately prior to such event; and if any
          reclassification also results in a change in Common Stock covered by (a) above,
          then such adjustment shall be made pursuant to both this paragraph (e) and
          paragraph (a). The provisions of this paragraph (e) shall similarly apply to
          successive re-classifications, or capital reorganizations, mergers or
          consolidations, sales or other transfers. 

-3- 

        If
the Company after the date hereof shall issue or agree to issue Common Stock, Options or
Convertible Securities, other than as described herein, and such issuance or agreement
would in the opinion of the Board of Directors of the Company materially affect the rights
of the Holders of the Representative’s Option, the Exercise Price and the number of
Option Shares purchasable upon exercise of the Representative’s Option shall be
adjusted in such matter, if any, and at such time as the Board of Directors of the
Company, in good faith, may determine to be equitable in the circumstances. The minutes or
unanimous consent approving such action shall set forth the Board of Director’s
determination as to whether an adjustment is warranted and the manner of such adjustment.
In the absence of such determination, any Holder may request in writing that the Board of
Directors make such determination. Any such determination made in good faith by the Board
of Directors shall be final and binding upon the Holders. If the Board fails, however, to
make such determination within sixty (60) days after such request, such failure shall be
deemed a determination that an adjustment is required. 

         (i)       
          Upon occurrence of each event requiring an adjustment of the Exercise Price and
          of the number of Option Shares purchasable upon exercise of this
          Representative’s Option in accordance with, and as required by, the terms
          hereof, the Company shall forthwith employ a firm of certified public
          accountants (who may be the regular accountants for the Company) who shall
          compute the adjusted Exercise Price and the adjusted number of Option Shares
          purchasable at such adjusted Exercise Price by reason of such event in
          accordance herewith. The Company shall give to each Holder of the
          Representative’s Option a copy of such computation which shall be
          conclusive and shall be binding upon such Holders unless contested by Holders by
          written notice to the Company within thirty (30) days after receipt thereof. 

         (ii)       
          In case the Company after the date hereof shall propose (A) to pay any dividend
          payable in stock to the holders of its Common Stock or to make any other
          distribution (other than cash dividends) to the holders of its Common Stock or
          to grant rights to subscribe to or purchase any additional shares of any class
          or any other rights or options, (B) to effect any reclassification involving
          merely the subdivision or combination of outstanding Common Stock, or (C) any
          capital reorganization or any consolidation or merger, or any sale, transfer or
          other disposition of its property, assets and business substantially as an
          entirety, or the liquidation, dissolution or winding up of the Company, then in
          each such case, the Company shall obtain the computation described above and if
          an adjustment to the Exercise Price is required, the Company shall notify the
          Holders of the Representative’s Option of such proposed action, which shall
          specify the record date for any such action or if no record date is established
          with respect thereto, the date on which such action shall occur or commence, or
          the date of participation therein by the holders of Common Stock if any such
          date is to be fixed, and shall also set forth such facts with respect thereto as
          shall be reasonably necessary to indicate the effect of such action on the
          Exercise Price and the number, or kind, or class of shares or other securities
          or property obtainable upon exercise of this Representative’s Option after
          giving effect to any adjustment which will be required as a result of such
          action. Such notice shall be given at least twenty (20) days prior to the record
          date for determining holders of the Common Stock for purposes of any such
          action, and in the case of any action for which a record date is not established
          then such notice shall be mailed at least twenty (20) days prior to the taking
          of such proposed action. 

-4- 

         (iii)       
          Failure to file any certificate or notice or to give any notice, or any defect
          in any certificate or notice, shall not affect the legality or validity of the
          adjustment in the Exercise Price or in the number, or kind, or class of shares
          or other securities or property obtainable upon exercise of the
          Representative’s Option or of any transaction giving rise thereto. 

           (f)       
          The Company shall not be required to issue fractional Option Shares upon any
          exercise of the Representative’s Option. As to any final fraction of a
          Share which the Holder of a Representative’s Option 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 the same fraction of the
          current market price of a share of such stock on the business day preceding the
          day of exercise. The Holder of a Representative’s Option, by his acceptance
          of a Representative’s Option, expressly waives any right to receive any
          fractional Option Shares. 

           (g)       
          Regardless of any adjustments pursuant to this section in the Exercise Price or
          in the number, or kind, or class of shares or other securities or other property
          obtainable upon exercise of a Representative’s Option, a
          Representative’s Option may continue to express the Exercise Price and the
          number of Option Shares obtainable upon exercise at the same price and number of
          Option Shares as are stated herein. 

           (h)       
          The number of Option Shares, the Exercise Price and all other terms and
          provisions of the Company’s agreement with the Holder of this
          Representative’s Option shall be determined exclusively pursuant to the
          provisions hereof. 

           (i)       
          The above provisions of this section 6 shall similarly apply to successive
          transactions which require adjustments. 

           (j)       
          Notwithstanding any other language to the contrary herein, (i) the anti-dilution
          terms of this Representative’s Option will not be enforced so as to provide
          the Holder the right to receive, or for the accrual of, cash dividends prior to
          the exercise of this Representative’s Option, and (ii) the anti-dilution
          terms of this Representative’s Option will not be enforced in such a manner
          as to provide the Holder with disproportionate rights, privileges and economic
          benefits not provided to purchasers of the Common Stock in the Public Offering. 

           7.       
          The issuance of any Option Shares or other securities upon the exercise of this
          Representative’s Option and the delivery of certificates or other
          instruments representing such securities, or other securities, shall be made
          without charge to the Holder for any tax or other charge in respect of such
          issuance. The Company shall not, however, be required to pay any tax which may
          be payable in respect of any transfer involved in the issue and delivery of any
          certificate in a name other than that of the Holder and the Company shall not be
          required to issue or deliver any such certificate unless and until the person or
          persons requesting the issue thereof shall have paid to the Company the amount
          of such tax or shall have established to the satisfaction of the Company that
          such tax has been paid. 

           8.       
          (a) If, at any time after ____________________ , 2005 (180 days after the
          Effective Date of the Registration Statement), and ending
          _________________, 20111 (five years after the Effective Date of the
          Registration Statement), the Company shall file a registration statement (other
          than on Form S-4, Form S-8, or any successor form) with the Securities and
          Exchange Commission (the “Commission”) while Option Shares are
          available for purchase upon exercise of this Representative’s Option or
          while any Option Shares (collectively, the “Representative’s Option
          and the underlying Option Shares, the “Representative’s
          Securities”) are outstanding, the Company shall, on one occasion only, give
          the Holder and all the then holders of such Representative’s Securities at
          least 30 days prior written notice of the filing of such registration statement.
          If requested by the Holder or by any such holder in writing within 20 days after
          receipt of any such notice, the Company shall, at the Company’s sole
          expense (other than the fees and disbursements of counsel for the Holder or such
          holder and the underwriting discounts and non-accountable expenses, if any,
          payable in respect of the securities sold by the Holder or any such holder),
          register or qualify the Option Shares of the Holder or any such holders who
          shall have made such request concurrently with the registration of such other
          securities, all to the extent requisite to permit the public offering and sale
          of the Option Shares requested to be registered, and will use its best efforts
          through its officers, directors, auditors and counsel to cause such registration
          statement to become effective as promptly as practicable. Notwithstanding the
          foregoing, if the managing underwriter of any such offering shall advise the
          Company in writing that, in its opinion, the distribution of all or a portion of
          the Option Shares requested to be included in the registration concurrently with
          the securities being registered by the Company would materially adversely affect
          the distribution of such securities by the Company for its own account, then the
          Holder or any such holder who shall have requested registration of his or its
          Option Shares shall delay the offering and sale of such Option Shares (or the
          portions thereof so designated by such managing underwriter) for such period,
          not to exceed 90 days, as the managing underwriter shall request, provided that
          no such delay shall be required as to any Option Shares if any securities of the
          Company are included in such registration statement for the account of any
          person other than the Company and the Holder unless the securities included in
          such registration statement for such other person shall have been reduced pro
          rata to the reduction of the Option Shares which were requested to be included
          in such registration. 

-5- 

           (b)       
          If at any time after _____________________, 2005 (180 days after the Effective
          Date of the Registration Statement), and before _________________, 2009
          (five years after the Effective Date of the Registration Statement), the Company
          shall receive a written request from holders of Representative’s Securities
          who, in the aggregate, own (or upon exercise of all Option Shares will own) a
          majority of the total number of Option Shares, the Company shall, as promptly as
          practicable, prepare and file with the Commission a registration statement
          sufficient to permit the public offering and sale of the Option Shares, and will
          use its best efforts through its officers, directors, auditors and counsel to
          cause such registration statement to become effective as promptly as
          practicable; provided, however, that the Company shall only be obligated to file
          and obtain effectiveness of one such registration statement for which all
          expenses incurred in connection with such registration (other than the fees and
          disbursements of counsel for the Holder or such holders and underwriting
          discounts and nonaccountable expenses, if any, payable in respect of the Option
          Shares sold by the Holder or any such holder) shall be borne by the Company. 

           (c)       
          In the event of a registration pursuant to the provisions of this paragraph 8,
          the Company shall use its best efforts to cause the Option Shares so requested
          to be registered or qualified for sale under the securities or blue sky laws of
          such jurisdictions as the Holder or such holders may reasonably request;
          provided, however, that the Company shall not be required to qualify to do
          business in any state by reason of this paragraph 8(c) in which it is not
          otherwise required to qualify to do business and provided further, that the
          Company has no obligation to qualify the Option Shares where such qualification
          would cause any unreasonable delay or expenditure by the Company. 

           (d)       
          The Company shall keep effective any registration or qualification contemplated
          by this paragraph 8 and shall from time to time amend or supplement each
          applicable registration statement, preliminary prospectus, final prospectus,
          application, document and communication for such period of time as shall be
          required to permit the Holder or such holders to complete the offer and sale of
          the Option Shares covered thereby. The Company shall in no event be required to
          keep any such registration or qualification in effect for a period in excess of
          nine months from the date on which the Holder and such holders are first free to
          sell such Option Shares; provided, however, that if the Company is required to
          keep any such registration or qualification in effect with respect to securities
          other than the Option Shares beyond such period, the Company shall keep such
          registration or qualification in effect as it relates to the Option Shares for
          so long as such registration or qualification remains or is required to remain
          in effect in respect of such other securities. 

           (e)       
          In the event of a registration pursuant to the provisions of this paragraph 8,
          the Company shall furnish to the Holder and to each such holder such reasonable
          number of copies of the registration statement and of each amendment and
          supplement thereto (in each case, including all exhibits), such reasonable
          number of copies of each prospectus contained in such registration statement and
          each supplement or amendment thereto (including each preliminary prospectus),
          all of which shall conform to the requirements of the Act and the rules and
          regulations thereunder, and such other documents as the Holder or such holders
          may reasonably request in order to facilitate the disposition of the Option
          Shares included in such registration. 

-6- 

           (f)       
          In the event of a registration pursuant to the provisions of this paragraph 8,
          the Company shall furnish the Holder and each holder of any Option Shares so
          registered with an opinion of its counsel to the effect that (i) the
          registration statement has become effective under the Act and no order
          suspending the effectiveness of the registration statement, preventing or
          suspending the use of the registration statement, any preliminary prospectus,
          any final prospectus, or any amendment or supplement thereto has been issued,
          nor to such counsel’s actual knowledge has the Securities and Exchange
          Commission or any securities or blue sky authority of any jurisdiction
          instituted or threatened to institute any proceedings with respect to such an
          order and (ii) the registration statement and each prospectus forming a part
          thereof (including each preliminary prospectus), and any amendment or supplement
          thereto, complies as to form with the Act and the rules and regulations
          thereunder. Such counsel shall also provide a Blue Sky Memorandum setting forth
          the jurisdictions in which the Option Shares have been registered or qualified
          for sale pursuant to the provisions of paragraph 8(c). 

           (g)       
          The Company agrees that until all the Option Shares have been sold under a
          registration statement or pursuant to Rule 144 under the Act, or until the
          Option Shares may be sold under Rule 144 (k), it shall keep current in filing
          all reports, statements and other materials required to be filed with the
          Commission to permit holders of the Option Shares to sell such securities under
          Rule 144. 

           (h)       
          The Holder and any holders who propose to register their Option Shares under the
          Act, shall execute and deliver to the Company a selling stockholder
          questionnaire on a form to be provided by the Company. 

           (i)       
          The Company shall not be required by the terms hereof to file a Registration
          Statement if, in the opinion of counsel to the holders of the Option Shares and
          counsel for the Company (or, should they not agree, in the opinion of another
          counsel experienced in securities law matters acceptable to counsel for the
          holders of Option Shares and the Company), the proposed public offering or other
          transfer as to which such Registration Statement is requested to be filed is
          exempt from applicable federal and state securities laws, rules, regulations and
          would result in unaffiliated purchasers or transferees obtaining securities that
          are not “restricted securities” as that term is defined in Rule 144
          under the Act. 

           9.       
          (a) Subject to the conditions set forth below, the Company agrees to indemnify
          and hold harmless the Holder, any holder of any of the Representative’s
          Securities, their officers, directors, partners, employees, agents and counsel,
          and each person, if any, who controls any such person within the meaning of
          Section 15 of the Act or Section 20(a) of the Securities Exchange Act of 1934,
          as amended (the “Exchange Act”), from and against any and all loss,
          liability, charge, claim, damage and expense whatsoever (which shall include,
          for all purposes of this Section 9, but not be limited to, attorneys’ fees
          and any and all expense whatsoever incurred in investigating, preparing or
          defending against any litigation, commenced or threatened, or any claim
          whatsoever, and any and all amounts paid in settlement of any claim or
          litigation), as and when incurred, arising out of, based upon, or in connection
          with (i) any untrue statement or alleged untrue statement of a material fact
          contained (A) in any registration statement, preliminary prospectus or final
          prospectus (as from time to time amended and supplemented), or any amendment or
          supplement thereto, or (B) in any application or other document or communication
          (in this Section 9 collectively called an “application”) executed by
          or on behalf of the Company or based upon written information furnished by or on
          behalf of the Company filed in any jurisdiction in order to register or qualify
          any of the Option Shares under the securities or blue sky laws thereof or filed
          with the Commission or any securities exchange; or any omission or alleged
          omission to state a material fact required to be stated therein or necessary to
          make the statements therein not misleading, unless such statement or omission
          was made in reliance upon and in conformity with written information furnished
          to the Company with respect to the Holder or any holder of any of the
          Representative’s Securities by or on behalf of such person expressly for
          inclusion in any registration statement, preliminary prospectus, or final
          prospectus, or any amendment or supplement thereto, or in any application, as
          the case may be, or (ii) any breach of any representation, warranty, covenant or
          agreement of the Company contained in this Representative’s Option. The
          foregoing agreement to indemnify shall be in addition to any liability the
          Company may otherwise have, including liabilities arising under this
          Representative’s Option. If any action is brought against the Holder or any
          holder of any of the Representative’s Securities or any of its officers,
          directors, partners, employees, agents or counsel, or any controlling persons of
          such person (an “indemnified party”) in respect of which indemnity may
          be sought against the Company pursuant to the foregoing paragraph, such
          indemnified party or parties shall promptly notify the Company in writing of the
          institution of such action (but the failure so to notify shall not relieve the
          Company from any liability it may otherwise have to Holder or any holder of any
          of the Representative’s Securities) and the Company shall promptly assume
          the defense of such action, including the employment of counsel (reasonably
          satisfactory to such indemnified party or parties) and payment of expenses. Such
          indemnified party or parties shall have the right to employ its or their own
          counsel in any such case, but the fees and expenses of such counsel shall be at
          the expense of such indemnified party or parties unless the employment of such
          counsel shall have been authorized in writing by the Company in connection with
          the defense of such action or the Company shall not have promptly employed
          counsel reasonably satisfactory to such indemnified party or parties to have
          charge of the defense of such action or such indemnified party or parties shall
          have reasonably concluded that there may be one or more legal defenses available
          to it or them or to other indemnified parties which are different from or
          additional to those available to the Company, in any of which events such fees
          and expenses shall be borne by the Company and the Company shall not have the
          right to direct the defense of such action on behalf of the indemnified party or
          parties. Anything in this paragraph to the contrary notwithstanding, the Company
          shall not be liable for any settlement of any such claim or action effected
          without its written consent. 

-7- 

           (b)       
          The Holder and each holder agrees to indemnify and hold harmless the Company,
          each director of the Company, each officer of the Company who shall have signed
          any registration statement covering the Option Shares held by the Holder and
          each holder and each other person, if any, who controls the Company within the
          meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, to the
          same extent as the foregoing indemnity from the Company to the Holder and each
          holder in paragraph 9(a), but only with respect to statements or omissions, if
          any, made in any registration statement, preliminary prospectus, or final
          prospectus (as from time to time amended and supplemented), or any amendment or
          supplement thereto, or in any application, in reliance upon and in conformity
          with written information furnished to the Company with respect to the Holder and
          each holder by or on behalf of the Holder and each holder expressly for
          inclusion in any such registration statement, preliminary prospectus, or final
          prospectus, or any amendment or supplement thereto, or in any application, as
          the case may be. If any action shall be brought against the Company or any other
          person so indemnified based on any such registration statement, preliminary
          prospectus, or final prospectus, or any amendment or supplement thereto, or in
          any application, and in respect of which indemnity may be sought against the
          Holder and each holder pursuant to this paragraph 9(b), the Holder and each
          holder shall have the rights and duties given to the Company, and the Company
          and each other person so indemnified shall have the rights and duties given to
          the indemnified parties, by the provisions of paragraph 9(a). 

           (c)       
          To provide for just and equitable contribution, if (i) an indemnified party
          makes a claim for indemnification pursuant to paragraph 9(a) or 9(b) (subject to
          the limitations thereof) but it is found in a final judicial determination, not
          subject to further appeal, that such indemnification may not be enforced in such
          case, even though this Agreement expressly provides for indemnification in such
          case, or (ii) any indemnified or indemnifying party seeks contribution under the
          Act, the Exchange Act or otherwise because the indemnification provided for in
          this Section 9 is for any reason held to be unenforceable by the Company and the
          Holder and any holder, then the Company (including for this purpose any
          contribution made by or on behalf of any director of the Company, any officer of
          the Company who signed any such registration statement and any controlling
          person of the Company), as one entity, and the Holder and any holder of any of
          the Option Shares included in such registration in the aggregate (including for
          this purpose any contribution by or on behalf of the Holder or any holder), as a
          second entity, shall contribute to the losses, liabilities, claims, damages and
          expenses whatsoever to which any of them may be subject, on the basis of
          relevant equitable considerations such as the relative fault of the Company and
          the Holder or any such holder in connection with the facts which resulted in
          such losses, liabilities, claims, damages and expenses. The relative fault, in
          the case of an untrue statement, alleged untrue statement, omission or alleged
          omission, shall be determined by, among other things, whether such statement,
          alleged statement, omission or alleged omission relates to information supplied
          by the Company, by the Holder or by any holder of Option Shares included in such
          registration, and the parties’ relative intent, knowledge, access to
          information and opportunity to correct or prevent such statement, alleged
          statement, omission or alleged omission. The Company and the Holder agree that
          it would be unjust and inequitable if the respective obligations of the Company
          and the Holder for contribution were determined by pro rata or per capita
          allocation of the aggregate losses, liabilities, claims, damages and expenses
          (even if the Holder and the other indemnified parties were treated as one entity
          for such purpose) or by any other method of allocation that does not reflect the
          equitable considerations referred to in this paragraph 9(c). No person guilty of
          a fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
          shall be entitled to contribution from any person who is not guilty of such
          fraudulent misrepresentation. For purposes of this paragraph 9(c), each person,
          if any, who controls the Holder or any holder of any of the
          Representative’s Securities within the meaning of Section 15 of the Act or
          Section 20(a) of the Exchange Act and each officer, director, partner, employee,
          agent and counsel of each such person, shall have the same rights to
          contribution as such person and each person, if any, who controls the Company
          within the meaning of Section 15 of the Act or Section 20(a) of the Exchange
          Act, each officer of the Company who shall have signed any such registration
          statement, and each director of the Company shall have the same rights to
          contribution as the Company, subject in each case to the provisions of this
          paragraph 9(c). Anything in this paragraph 9(c) to the contrary notwithstanding,
          no party shall be liable for contribution with respect to the settlement of any
          claim or action effected without its written consent. This paragraph 9(c) is
          intended to supersede any right to contribution under the Act, the Exchange Act
          or otherwise. 

-8- 

           10.       
          Unless the Option Shares have been registered or an exemption from such
          registration is available, the Option Shares issued upon exercise of this
          Representative’s Option shall be subject to a stop transfer order and the
          certificate or certificates evidencing any such Option Shares shall bear the
          following legend or a legend substantially similar thereto: 

THESE SECURITIES HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, NOR HAVE THEY BEEN REGISTERED UNDER THE
SECURITIES (“BLUE SKY”) LAWS OF ANY STATE. THESE SECURITIES MAY NOT BE SOLD,
TRANSFERRED, PLEDGED, OR HYPOTHECATED UNLESS THEY HAVE FIRST BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 AND UNDER THE APPLICABLE STATE SECURITIES (“BLUE SKY”)
LAWS OR UNLESS THE AVAILABILITY OF AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND LAWS
IS ESTABLISHED TO THE SATISFACTION OF THE COMPANY, WHICH MAY NECESSITATE A WRITTEN OPINION
OF SELLER’S COUNSEL SATISFACTORY TO COMPANY COUNSEL. 

           11.       
          Upon receipt of evidence satisfactory to the Company of the loss, theft,
          destruction or mutilation of any Representative’s Option (and upon
          surrender of any Representative’s Option if mutilated), and upon
          reimbursement of the Company’s reasonable incidental expenses, including
          the posting of a lost penalty bond if necessary, the Company shall execute and
          deliver to the Holder thereof a new Representative’s Option of like date,
          tenor and denomination. 

           12.       
          The Holder of any Representative’s Option shall not have, solely on account
          of such status, any rights of a stockholder of the Company, either at law or in
          equity, or to any notice of meetings of stockholders or of any other proceedings
          of the Company, except as provided in this Representative’s Option. 

           13.       
          This Representative’s Option shall be construed in accordance with the laws
          of the State of Colorado, without giving effect to conflict of laws.

-12-EXHIBIT 4.6 

Explanatory note to
attached: 

Representative’s
Option for the Purchase of Warrants 

        The
Representative is a co-managing underwriter pursuant to an Underwriting Agreement dated
_____________________, 2005 (“Underwriting Agreement”) with A4S Technologies,
Inc.. (“A4S”) relating to the offering of 1,800,000 Units of A4S. Each Unit
consists of one share of A4S’s common stock and one warrant to purchase common stock,
all as more fully described in the Underwriting Agreement and in a Warrant Agreement dated
____________________ , 2005 between A4S and Registrar and Transfer Company, as warrant
agent. 

        The
Units will be traded on the Nasdaq Small Cap Market until such time as A4S has (i)
delivered a Notice of Separation to holders of Units and the warrant agent advising that
the Units can be detached and separated into common stock and warrants; and (ii) provided
for the separate listing of such common shares and warrants on the Nasdaq Small Cap
Market. Each Unit will be divided into its separate component of one share of common stock
and one warrant upon the earlier of one year from the date of the Underwriting Agreement,
or upon thirty (30) days prior written notice from the Company. However, the Company will
not allow separation of the Units until the earlier to occur of 60 days immediately
following the date of the Underwriting Agreement or the exercise by the underwriters of
their entire over-allotment option as provided in the Underwriting Agreement. Since the
underwriters’ options and warrants are not exercisable for 180 days from the date of
issuance, the attached Representative’s Options assume that the Units have been
separated into their separate component parts of common stock and warrants.

Representative’s
Option for the Purchase of Warrants  

		
	       No. UWW-001
	_________  Representative's Options

        THIS
CERTIFIES that, for receipt in hand of $90.00 and other value received (the "Purchase
Price"), BATHGATE CAPITAL PARTNERS LLC. (the "Holder"), is entitled to subscribe for and
purchase from A4S TECHNOLOGIES, INC., a Colorado corporation (the "Company"), upon the
terms and conditions set forth herein, at any time, or from time to time, after
_____________________, 2005 and before 5:00 p.m. Colorado time on _____________________,
2010 (the "Exercise Period"), ____________________ Warrants (a "Warrant" or the
"Warrants") of the Company at an exercise price of $.12 per Representative's Option, or
120% of the assumed $0.10 offering price of the warrants included in the Units to be sold
by the Company in a public offering under the Registration Statement (as defined below).
Each Warrant shall be identical to the warrants sold in the public offering to be
underwritten by the Holder (the "Public Offering") except that the Warrants hereunder
shall not be redeemable by the Company and shall be exercisable on a "cashless basis" as
described in Section 2(c) below. Each Warrant shall be exercisable to purchase one share
of Common Stock (a "Warrant Share") at a price of $ ____________________ (120% of the
exercise price of the Warrants sold in the Public Offering; the "Exercise Price") until
____________________ , 2010, which is five years from the date on which the Company's
Registration Statement on Form S-1, Registration No. 333-119737 (the "Registration
Statement") was declared effective by the Securities and Exchange Commission (the
"Effective Date"). 

        The
term the "Holder" as used herein shall include any transferee to whom this
Representative's Option has been transferred in accordance with the terms of this
Representative's Option. As used herein the term "this Representative's Option" shall
mean and include this Representative's Option and any Representative's Option or
Representative's Options hereafter issued as a consequence of the exercise or transfer of
this Representative's Option in whole or in part, but shall exclude the Warrants, and the
term "Common Stock" shall mean and include the Company's Common Stock with ordinary
voting power, which class at the date hereof is publicly traded. 

        1.    
      This Representative's Option may not be sold, transferred, assigned, pledged or
hypothecated until ____________________ , 2005 (180 days from the Effective Date of the
Registration Statement) except that it may be transferred, in whole or in part, (i) to
one or more officers or partners of the Holder (or the officers or partners of any such
partner); (ii) to a member of the underwriting syndicate and/or its officers or partners;
or (iii) by operation of law. After _____________________, 2005, this Representative's
Option may be sold, transferred, assigned or hypothecated in accordance with applicable
law. 

         

        2.    
(a)   This Representative's Option may be exercised during the Exercise Period as to the
whole or any lesser number of Warrants, by the surrender of this Representative's Option
(with the election attached hereto duly executed) to the Company at its office at 4920
South Lewis Avenue, Suite 107, Tulsa, Oklahoma 74105, or such other place as is
designated in writing by the Company, together with a certified or bank cashier's check
payable to the order of the Company in an amount equal to the Purchase Price. 

        (b)    
     Following exercise of this Representative's Option, and at any time thereafter
through and until expiration of the Warrants, the Holder may exercise the Warrants
underlying this Representative's Option by tendering a notice of exercise, together with
a certified or bank cashier's check payable to the order of the Company, in an amount
equal to the Exercise Price multiplied by the number of Warrant Shares as to which such
exercise relates. 

        (c)    
     Upon written request of the Holder, and in lieu of payment of the Exercise Price of
the Warrants by check in accordance with paragraph 2(b) hereof, the Holder may exercise
the Warrants (or any portion thereof) for and receive the number of Shares equal to a
fraction, the numerator of which equals (i) the amount by which the average of the
Current Market Price of the Common Stock for the three days preceding the date of
exercise exceeds the Exercise Price per Warrant, multiplied by (ii) the number of Warrant
Shares to be purchased; the denominator of which equals the Current Market Price. 

        (d)    
     For the purposes of any computation under this Representative's Option, the "Current
Market Price" at any date shall be the closing price of the Common Stock on the business
day next preceding the event requiring an adjustment hereunder. If the principal trading
market for such securities is an exchange, the closing price shall be the reported last
sale price on such exchange on such day provided if trading of such Common Stock is
listed on any consolidated tape, the closing price shall be the reported last sale price
set forth on such consolidated tape. If the principal trading market for such securities
is the over-the-counter market, the closing price shall be the last reported sale price
on such date as set forth by The Nasdaq Stock Market, Inc., or, if the security is not
quoted on such market, the average closing bid and asked prices as set forth in the
National Quotation Bureau pink sheet or the Electronic Bulletin Board System for such
day. Notwithstanding the foregoing, if there is no reported last sale price or average
closing bid and asked prices, as the case may be, on a date prior to the event requiring
an adjustment hereunder, then the Current Market Price shall be determined as of the
latest date prior to such day for which such last sale price or average closing bid and
asked price is available. 

        3.    
         Upon each exercise of this Representative's Option, the Holder shall be deemed
to be the holder of record of the Warrants issuable upon such exercise, notwithstanding
that the transfer books of the Company shall then be closed or certificates representing
such Warrants shall not then have been actually delivered to the Holder. As soon as
practicable after each such exercise of this Representative's Option, the Company shall
issue and deliver to the Holder a certificate or certificates for the Warrants issuable
upon such exercise, registered in the name of the Holder or its designee. If this
Representative's Option should be exercised in part only, the Company shall, upon
surrender of this Representative's Option for cancellation, execute and deliver a new
Representative's Option evidencing the right of the Holder to purchase the balance of the
Warrants (or portions thereof) subject to purchase hereunder. 

        4.    
      Any warrants issued upon the transfer or exercise in part of this Representative's
Option (together with this Representative's Option, the "Representative's Options") shall
be numbered and shall be registered in a Representative's Option Register as they are
issued. The Company shall be entitled to treat the registered holder of any
Representative's Option on the Representative's Option Register as the owner in fact
thereof for all purposes and shall not be bound to recognize any equitable or other claim
to or interest in such Representative's Option on the part of any other person. The
Representative's Options shall be transferable only on the books of the Company upon
delivery thereof duly endorsed by the Holder or by his duly authorized attorney or
representative, or accompanied by proper evidence of succession, assignment or authority
to transfer. In all cases of transfer by an attorney, executor, administrator, guardian
or other legal representative, duly authenticated evidence of his or its authority shall
be produced. Upon any registration of transfer, the Company shall deliver a new
Representative's Option or Representative's Options to the person entitled thereto. The
Representative's Options may be exchanged, at the option of the Holder thereof, for
another Representative's Option, or other Representative's Options of different
denominations, of like tenor and representing in the aggregate the right to purchase a
like number of Warrants (or portions thereof) upon surrender to the Company or its duly
authorized agent. Notwithstanding the foregoing, the Company shall have no obligation to
cause Representative's Options to be transferred on its books to any person if, in the
opinion of counsel to the Company, such transfer does not comply with the provisions of
the Securities Act of 1933, as amended (the "Act"), or applicable state blue sky laws and
the rules and regulations thereunder. 

-2- 

        5.    
      The Company shall at all times reserve and keep available out of its authorized and
unissued Common Stock, solely for the purpose of providing for the exercise of this
Representative's Option and the Warrants purchasable upon exercise of this
Representative's Option, such number of shares of Common Stock as shall, from time to
time, be sufficient therefor. The Company covenants that all shares of Common Stock
issuable upon exercise of Warrants underlying this Representative's Option shall be
validly issued, fully paid, nonassessable, and free of preemptive rights. 

        6.    
      The rights and privileges of the Warrants issuable on exercise of this
Representative's Option shall be as provided in the warrant certificate (the "Warrant
Certificate") to be delivered to the Holder on exercise of this Representative's Option.
All anti-dilution and other rights shall be as provided for in the Warrant Certificate
and as set forth in the warrant agreement by and between the Company and the Warrant
Agent for the Company (the "Warrant Agreement"). The provisions of the Warrant Agreement
relating to anti-dilution rights and any other rights and privileges granted to holders
of publicly traded Warrants are incorporated by reference herein as if more fully set
forth herein. Notwithstanding any other language to the contrary herein or in the Warrant
Agreement by and between the Company and the Warrant Agent, in the event, prior to the
exercise of this Warrant, Holders of publicly-traded Warrants shall be entitled to the
benefit of any anti-dilution provisions of the Warrant Agreement or the Warrant
Certificate then, in such event, the Warrants issuable upon exercise of this
Representative's Option shall be adjusted in accordance with the provisions of the
anti-dilution provisions of the Warrant Certificate and the Warrant Agreement in a manner
identical to the adjustments made pursuant to the anti-dilution provisions and other
rights and privileges applicable to publicly-traded warrants. Any such adjustment may be
made at or immediately following the date of exercise hereof. Notwithstanding any other
language to the contrary herein, (i) the anti-dilution terms of this Representative's
Option will not be enforced so as to provide the Holder the right to receive, or for the
accrual of, cash dividends prior to the exercise of this Representative's Option, and
(ii) the anti-dilution terms of this Representative's Option will not be enforced in such
a manner as to provide the Holder with disproportionate rights, privileges and economic
benefits not provided to purchasers of Warrants as part of the Units in the Public
Offering. 

        7.    
      The issuance of any Warrants or other securities upon the exercise of this
Representative's Option or any Warrant Shares upon the exercise of the Warrants, and the
delivery of certificates or other instruments representing such securities, or other
securities, shall be made without charge to the Holder for any tax or other charge in
respect of such issuance. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and delivery of any
certificate in a name other than that of the Holder and the Company shall not be required
to issue or deliver any such certificate unless and until the person or persons
requesting the issue thereof shall have paid to the Company the amount of such tax or
shall have established to the satisfaction of the Company that such tax has been paid. 

        8.    
(a)   If, at any time after ____________________ , 2005 (180 days after the Effective
Date of the Registration Statement), and ending _____________________, 2011 (six years
after the Effective Date of the Registration Statement), the Company shall file a
registration statement (other than on Form S-4, Form S-8, or any successor form) with the
Securities and Exchange Commission (the "Commission") while Warrants are available for
purchase upon exercise of this Representative's Option or while any Warrants or Warrant
Shares (collectively, the "Representative's Securities") are outstanding, the Company
shall give the Holder and all the then holders of such Representative's Options and
Representative's Securities at least 30 days prior written notice of the filing of such
registration statement. If requested by the Holder or by any such holder in writing
within 20 days after receipt of any such notice, the Company shall, at the Company's sole
expense (other than the fees and disbursements of counsel for the Holder or such holder
and the underwriting discounts and unaccountable expenses, if any, payable in respect of
the securities sold by the Holder or any such holder), register or qualify the
Representative's Securities of the Holder or any such holders who shall have made such
request concurrently with the registration of such other securities, all to the extent
requisite to permit the public offering and sale of the Representative's Securities, and
will use its best efforts through its officers, directors, auditors and counsel to cause
such registration statement to become effective as promptly as practicable.
Notwithstanding the foregoing, if the managing underwriter of any such offering shall
advise the Company in writing that, in its opinion, the distribution of all or a portion
of the Representative's Securities requested to be included in the registration
concurrently with the securities being registered by the Company would materially
adversely affect the distribution of such securities by the Company for its own account,
then the Holder or any such holder who shall have requested registration of his or its
Representative's Securities shall delay the offering and sale of such Representative's
Securities (or the portions thereof so designated by such managing underwriter) for such
period, not to exceed 90 days, as the managing underwriter shall request, provided that
no such delay shall be required as to any Representative's Securities if any securities
of the Company are included in such registration statement for the account of any person
other than the Company and the Holder unless the securities included in such registration
statement for such other person shall have been reduced pro rata to the reduction of the
Representative's Securities which were requested to be included in such registration. 

-3- 

        (b)    
     If at any time after _____________________, 2005 (180 days after the Effective Date
of the Registration Statement), and before _____________________, 2010 (five years after
the Effective Date of the Registration Statement), the Company shall receive a written
request from holders of Representative's Securities who, in the aggregate, own (or upon
exercise of all Representative's Options will own) a majority of the total number of
Representative's Securities, the Company shall, as promptly as practicable, prepare and
file with the Commission a registration statement sufficient to permit the public
offering and sale of the Representative's Securities, and will use its best efforts
through its officers, directors, auditors and counsel to cause such registration
statement to become effective as promptly as practicable; provided, however, that the
Company shall only be obligated to file and obtain effectiveness of one such registration
statement for which all expenses incurred in connection with such registration (other
than the fees and disbursements of counsel for the Holder or such holders and
underwriting discounts and unaccountable expenses, if any, payable in respect of the
Representative's Securities sold by the Holder or any such holder) shall be borne by the
Company. 

        (c)    
     In the event of a registration pursuant to the provisions of this paragraph 8, the
Company shall use its best efforts to cause the Representative's Securities so registered
to be registered or qualified for sale under the securities or blue sky laws of such
jurisdictions as the Holder or such holders may reasonably request; provided, however,
that the Company shall not be required to qualify to do business in any state by reason
of this paragraph 8(c) in which it is not otherwise required to qualify to do business
and provided further, that the Company has no obligation to qualify the Representative's
Securities where such qualification would cause any unreasonable delay or expenditure by
the Company. 

        (d)    
     The Company shall keep effective any registration or qualification contemplated by
this paragraph 8 and shall from time to time amend or supplement each applicable
registration statement, preliminary prospectus, final prospectus, application, document
and communication for such period of time as shall be required to permit the Holder or
such holders to complete the offer and sale of the Representative's Securities covered
thereby. The Company shall in no event be required to keep any such registration or
qualification in effect for a period in excess of nine months from the date on which the
Holder and such holders are first free to sell such Representative's Securities;
provided, however, that if the Company is required to keep any such registration or
qualification in effect with respect to securities other than the Representative's
Securities beyond such period, the Company shall keep such registration or qualification
in effect as it relates to the Representative's Securities for so long as such
registration or qualification remains or is required to remain in effect in respect of
such other securities. 

        (e)    
     In the event of a registration pursuant to the provisions of this paragraph 8, the
Company shall furnish to the Holder and to each such holder such reasonable number of
copies of the registration statement and of each amendment and supplement thereto (in
each case, including all exhibits), such reasonable number of copies of each prospectus
contained in such registration statement and each supplement or amendment thereto
(including each preliminary prospectus), all of which shall conform to the requirements
of the Act and the rules and regulations thereunder, and such other documents as the
Holder or such holders may reasonably request in order to facilitate the disposition of
the Representative's Securities included in such registration. 

-4- 

        (f)    
     In the event of a registration pursuant to the provisions of this paragraph 8, the
Company shall furnish the Holder and each holder of any Representative's Securities so
registered with an opinion of its counsel to the effect that the registration statement
has become effective under the Act and no order suspending the effectiveness of the
registration statement, preventing or suspending the use of the registration statement,
any preliminary prospectus, any final prospectus, or any amendment or supplement thereto
has been issued, nor to such counsel's actual knowledge has the Securities and Exchange
Commission or any securities or blue sky authority of any jurisdiction instituted or
threatened to institute any proceedings with respect to such an order and (ii) the
registration statement and each prospectus forming a part thereof (including each
preliminary prospectus), and any amendment or supplement thereto, complies as to form
with the Act and the rules and regulations thereunder. Such counsel shall also provide a
Blue Sky Memorandum setting forth the jurisdictions in which the Representative's
Securities have been registered or qualified for sale pursuant to the provisions of
paragraph 8(c). 

        (g)    
     The Company agrees that until all the Representative's Securities have been sold
under a registration statement or pursuant to Rule 144 under the Act or until the
Representative's Securities may be sold under Rule 144(k), it shall keep current in
filing all reports, statements and other materials required to be filed with the
Commission to permit holders of the Representative's Securities to sell such securities
under Rule 144. 

        (h)    
     The Holder and any holders who propose to register their Representative's Securities
under the Act shall execute and deliver to the Company a selling stockholder
questionnaire on a form to be provided by the Company. 

        (i)    
     The Company shall not be required by the terms hereof to file a Registration
Statement if, in the opinion of counsel to the holders of the Representative's Securities
and counsel for the Company (or, should they not agree, in the opinion of another counsel
experienced in securities law matters acceptable to counsel for the holders of
Representative's Securities and the Company), the proposed public offering or other
transfer as to which such Registration Statement is requested to be filed is exempt from
applicable federal and state securities laws, rules, regulations and would result in
unaffiliated purchasers or transferees obtaining securities that are not "restricted
securities" as that term is defined in Rule 144 under the Act. 

        9.    
(a)   Subject to the conditions set forth below, the Company agrees to indemnify and hold
harmless the Holder, any holder of any of the Representative's Securities, their
officers, directors, partners, employees, agents and counsel, and each person, if any,
who controls any such person within the meaning of Section 15 of the Act or Section 20(a)
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and against
any and all loss, liability, charge, claim, damage and expense whatsoever (which shall
include, for all purposes of this Section 9, but not be limited to, attorneys' fees and
any and all expense whatsoever incurred in investigating, preparing or defending against
any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts
paid in settlement of any claim or litigation), as and when incurred, arising out of,
based upon, or in connection with (i) any untrue statement or alleged untrue statement of
a material fact contained (A) in any registration statement, preliminary prospectus or
final prospectus (as from time to time amended and supplemented), or any amendment or
supplement thereto, or (B) in any application or other document or communication (in this
Section 9 collectively called an "application") executed by or on behalf of the Company
or based upon written information furnished by or on behalf of the Company filed in any
jurisdiction in order to register or qualify any of the Representative's Securities under
the securities or blue sky laws thereof or filed with the Commission or any securities
exchange; or any omission or alleged omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, unless such
statement or omission was made in reliance upon and in conformity with written
information furnished to the Company with respect to the Holder or any holder of any of
the Representative's Securities by or on behalf of such person expressly for inclusion in
any registration statement, preliminary prospectus, or final prospectus, or any amendment
or supplement thereto, or in any application, as the case may be, or (ii) any breach of
any representation, warranty, covenant or agreement of the Company contained in this
Representative's Option. The foregoing agreement to indemnify shall be in addition to any
liability the Company may otherwise have, including liabilities arising under this
Representative's Option. 

-5- 

        If
any action is brought against the Holder or any holder of any of the Representative's
Securities or any of its officers, directors, partners, employees, agents or counsel, or
any controlling persons of such person (an "indemnified party") in respect of which
indemnity may be sought against the Company pursuant to the foregoing paragraph, such
indemnified party or parties shall promptly notify the Company in writing of the
institution of such action (but the failure so to notify shall not relieve the Company
from any liability it may otherwise have to Holder or any holder of any of the
Representative's Securities) and the Company shall promptly assume the defense of such
action, including the employment of counsel (reasonably satisfactory to such indemnified
party or parties) and payment of expenses. Such indemnified party or parties shall have
the right to employ its or their own counsel in any such case, but the fees and expenses
of such counsel shall be at the expense of such indemnified party or parties unless the
employment of such counsel shall have been authorized in writing by the Company in
connection with the defense of such action or the Company shall not have promptly
employed counsel reasonably satisfactory to such indemnified party or parties to have
charge of the defense of such action or such indemnified party or parties shall have
reasonably concluded that there may be one or more legal defenses available to it or them
or to other indemnified parties which are different from or additional to those available
to the Company, in any of which events such fees and expenses shall be borne by the
Company and the Company shall not have the right to direct the defense of such action on
behalf of the indemnified party or parties. Anything in this paragraph to the contrary
notwithstanding, the Company shall not be liable for any settlement of any such claim or
action effected without its written consent. 

        (b)    
     The Holder and each holder agrees to indemnify and hold harmless the Company, each
director of the Company, each officer of the Company who shall have signed any
registration statement covering the Representative's Securities held by the Holder and
each holder and each other person, if any, who controls the Company within the meaning of
Section 15 of the Act or Section 20(a) of the Exchange Act, to the same extent as the
foregoing indemnity from the Company to the Holder and each holder in paragraph 9(a), but
only with respect to statements or omissions, if any, made in any registration statement,
preliminary prospectus, or final prospectus (as from time to time amended and
supplemented), or any amendment or supplement thereto, or in any application, in reliance
upon and in conformity with written information furnished to the Company with respect to
the Holder and each holder by or on behalf of the Holder and each holder expressly for
inclusion in any such registration statement, preliminary prospectus, or final
prospectus, or any amendment or supplement thereto, or in any application, as the case
may be. If any action shall be brought against the Company or any other person so
indemnified based on any such registration statement, preliminary prospectus, or final
prospectus, or any amendment or supplement thereto, or in any application, and in respect
of which indemnity may be sought against the Holder and each holder pursuant to this
paragraph 9(b), the Holder and each holder shall have the rights and duties given to the
Company, and the Company and each other person so indemnified shall have the rights and
duties given to the indemnified parties, by the provisions of paragraph 9(a). 

        (c)    
     To provide for just and equitable contribution, if (i) an indemnified party makes a
claim for indemnification pursuant to paragraph 9(a) or 9(b) (subject to the limitations
thereof) but it is found in a final judicial determination, not subject to further
appeal, that such indemnification may not be enforced in such case, even though this
Agreement expressly provides for indemnification in such case, or (ii) any indemnified or
indemnifying party seeks contribution under the Act, the Exchange Act or otherwise
because the indemnification provided for in this Section 9 is for any reason held to be
unenforceable by the Company and the Holder and any holder, then the Company (including
for this purpose any contribution made by or on behalf of any director of the Company,
any officer of the Company who signed any such registration statement and any controlling
person of the Company), as one entity, and the Holder and any holder of any of the
Representative's Securities included in such registration in the aggregate (including for
this purpose any contribution by or on behalf of the Holder or any holder), as a second
entity, shall contribute to the losses, liabilities, claims, damages and expenses
whatsoever to which any of them may be subject, on the basis of relevant equitable
considerations such as the relative fault of the Company and the Holder or any such
holder in connection with the facts which resulted in such losses, liabilities, claims,
damages and expenses. The relative fault, in the case of an untrue statement, alleged
untrue statement, omission or alleged omission, shall be determined by, among other
things, whether such statement, alleged statement, omission or alleged omission relates
to information supplied by the Company, by the Holder or by any holder of
Representative's Securities included in such registration, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent such
statement, alleged statement, omission or alleged omission. The Company and the Holder
agree that it would be unjust and inequitable if the respective obligations of the
Company and the Holder for contribution were determined by pro rata or per capita
allocation of the aggregate losses, liabilities, claims, damages and expenses (even if
the Holder and the other indemnified parties were treated as one entity for such purpose)
or by any other method of allocation that does not reflect the equitable considerations
referred to in this paragraph 9(c). No person guilty of a fraudulent misrepresentation
(within the meaning of Section 11 (f) of the Act) shall be entitled to contribution from
any person who is not guilty of such fraudulent misrepresentation. For purposes of this
paragraph 9(c), each person, if any, who controls the Holder or any holder of any of the
Representative's Securities within the meaning of Section 15 of the Act or Section 20(a)
of the Exchange Act and each officer, director, partner, employee, agent and counsel of
each such person, shall have the same rights to contribution as such person and each
person, if any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, each officer of the Company who shall have signed any
such registration statement, and each director of the Company shall have the same rights
to contribution as the Company, subject in each case to the provisions of this paragraph
9(c). Anything in this paragraph 9(c) to the contrary notwithstanding, no party shall be
liable for contribution with respect to the settlement of any claim or action effected
without its written consent. This paragraph 9(c) is intended to supersede any right to
contribution under the Act, the Exchange Act or otherwise. 

-6- 

        10.    
The securities issued upon exercise of the Representative's Options shall be subject to a
stop transfer order and the certificate or certificates evidencing any such securities
shall bear the following legend or a legend substantially similar thereto: 

        THE
SECURITIES REPRESENTED BY THIS CERTIFICATE AND THE SECURITIES ISSUABLE UPON EXERCISE
HEREOF (THE "SECURITIES") HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, PURSUANT TO A REGISTRATION STATEMENT FILED WITH THE SECURITIES AND EXCHANGE
COMMISSION AND WITH THE SECURITIES ADMINISTRATORS OF CERTAIN STATES UNDER THE SECURITIES
("BLUE SKY") LAWS OF SUCH STATES. HOWEVER, NEITHER THE REPRESENTATIVE'S OPTIONS NOR SUCH
SECURITIES MAY BE SOLD, TRANSFERRED, PLEDGED, OR HYPOTHECATED EXCEPT PURSUANT TO (i) A
POST-EFFECTIVE AMENDMENT TO SUCH REGISTRATION STATEMENT, (ii) A SEPARATE REGISTRATION
STATEMENT UNDER SUCH ACT, OR (iii) AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND
UNDER THE APPLICABLE BLUE SKY LAWS. 

        11.    
     Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction
or mutilation of any Representative's Option (and upon surrender of any Representative's
Option if mutilated), and upon reimbursement of the Company's reasonable incidental
expenses, including the posting of a lost certificate bond, if necessary, the Company
shall execute and deliver to the Holder thereof a new Representative's Option of like
