                          -----------------------------

No. 28                                                 Void after March 29, 2010

      THIS CERTIFIES THAT, for value received, Excipio Group, S.A. (the
"Holder") is entitled to subscribe for and purchase 570,000 shares (as such
number of shares shall be adjusted pursuant to Section 3 hereof, thus adjusting
the per share Exercise Price) of the fully paid and nonassessable Common Stock,
$0.001 par value (the "Shares"), of TechAlt, Inc., a Nevada corporation (the
"Company"), at the exercise price of $1.00 per share (the "Exercise Price"),
subject to the provisions and upon the terms and conditions hereinafter set
forth.

      1. Method of Exercise; Payment.

      (a) Cash Exercise. The purchase rights represented by this Warrant may be
exercised by the Holder, in whole or in part, by the surrender of this Warrant
(with the notice of exercise form attached hereto as Exhibit A duly executed) at
the principal office of the Company, and by the payment to the Company, by
certified, cashier's or other check acceptable to the Company or by wire
transfer to an account designated by the Company, of an amount equal to the
aggregate Exercise Price of the Shares being purchased.

      (b) Cashless Exercise. In lieu of exercising this Warrant, the Holder may
elect to receive Shares equal to the value of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant at the principal office of
the Company together with notice of such election, in which event the Company
shall issue to the Holder a number of Shares computed using the following
formula:

<PAGE>

                  X = Y (A-B)
                      -------
                          A

      Where X = the number of the Shares to be issued to the Holder.

      Y = the number of the Shares purchasable under this Warrant.

      A = the fair market value of one Share on the date of determination.

      B = the per share Exercise Price (as adjusted to the date of such
          calculation).

      (c) Fair Market Value. For purposes of this Section 1, the per share fair
market value of the Shares shall mean:

            (i) If the Company's Common Stock is publicly traded, the per share
      fair market value of the Shares shall be the average of the closing prices
      of the Common Stock as quoted on the Over The Counter Bulletin Board or
      the principal exchange on which the Common Stock is listed, or if not so
      listed then the fair market value shall be the average of the closing bid
      prices of the Common Stock as published in The Wall Street Journal, in
      each case for the fifteen (15) trading days ending five (5) trading days
      prior to the date of determination of fair market value;

            (ii) If the Company's Common Stock is not so publicly traded, the
      per share fair market value of the Shares shall be such fair market value
      as is determined in good faith by the Board of Directors of the Company
      after taking into consideration factors it deems appropriate, including,
      without limitation, recent sale and offer prices of the capital stock of
      the Company in private transactions negotiated at arm's length.

      (d) Stock Certificates. In the event of any exercise of the rights
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

      (e) Limitations on Exercise. The Company shall not effect the exercise of
this Warrant, and no Person (as defined below) who is a holder of this Warrant
shall have the right to exercise this Warrant, to the extent that after giving
effect to such exercise, such Person (together with such Person's affiliates)
would beneficially own in excess of 9.99% of the shares of the Common Stock
outstanding immediately after giving effect to such exercise. For purposes of
the foregoing sentence, the aggregate number of shares of Common Stock
beneficially owned by such Person and its affiliates shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which the determination of such sentence is being made, but shall exclude shares
of Common Stock which would be issuable upon (i) exercise of the remaining,
unexercised portion of this Warrant beneficially owned by such Person and its
affiliates and (ii) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company beneficially owned by such Person
and its affiliates (including, without limitation, any convertible notes or
convertible preferred stock or warrants) subject to a limitation on conversion
or exercise analogous to the limitation contained herein. Except as set forth in
the preceding sentence, for purposes of this paragraph, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Securities Exchange
Act of 1934, as amended. For purposes of this Warrant, in determining the number
of outstanding shares of Common Stock the Holder may rely on the number of
outstanding shares of Common Stock as reflected in (1) the Company's most recent
Form 10-Q or 10-QSB, as applicable, Form 10-K or 10-KSB, as applicable, or other
public filing with the Securities and Exchange Commission, as the case may be,
(2) a more recent public announcement by the Company or (3) any other notice by
the Company or its Transfer Agent setting forth the number of shares of Common
Stock outstanding. For any reason at any time, upon the written or oral request
of the Holder, the Company shall within one Business Day confirm in writing to
the Holder the number of shares of Common Stock then outstanding.

      2. Stock Fully Paid; Reservation of Shares. All of the Shares issuable
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all taxes, liens and charges with respect to the issue thereof. During
the period within which the rights represented by this Warrant may be exercised,
the Company shall at all times have authorized and reserved for issuance
sufficient shares of its Common Stock to provide for the exercise of the rights
represented by this Warrant.

      3. Adjustments. Subject to the provisions of Section 11 hereof, the number
and kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price therefor shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

      (a) Reclassification. In the case of any reclassification or change of
securities of the class issuable upon exercise of this Warrant (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination), or in case of any
merger of the Company with or into another corporation (other than a merger with
another corporation in which the Company is the acquiring and the surviving
corporation and which does not result in any reclassification or change of
outstanding securities issuable upon exercise of this Warrant), or in case of
any sale of all or substantially all of the assets of the Company, the Company,
or such successor or purchasing corporation, as the case may be, shall duly
execute and deliver to the holder of this Warrant a new Warrant (in form and
substance reasonably satisfactory to the holder of this Warrant), or the Company
shall make appropriate provision without the issuance of a new Warrant, so that
the holder of this Warrant shall have the right to receive, at a total purchase
price not to exceed that payable upon the exercise of the unexercised portion of
this Warrant, and in lieu of the shares of Common Stock theretofore issuable
upon exercise of this Warrant, (i) the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
merger or sale by a holder of the number of shares of Common Stock then
purchasable under this Warrant, or (ii) in the case of such a merger or sale in
which the consideration paid consists all or in part of assets other than
securities of the successor or purchasing corporation, at the option of the
Holder of this Warrant, the securities of the successor or purchasing
corporation having a value at the time of the transaction equivalent to the fair
market value of the Common Stock at the time of the transaction. The provisions
of this subparagraph (a) shall similarly apply to successive reclassifications,
changes, mergers and transfers.

                                       3

      (b) Stock Splits, Dividends and Combinations. In the event that the
Company shall at any time subdivide the outstanding shares of Common Stock or
shall issue a stock dividend on its outstanding shares of Common Stock the
number of Shares issuable upon exercise of this Warrant immediately prior to
such subdivision or to the issuance of such stock dividend shall be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine the
outstanding shares of Common Stock the number of Shares issuable upon exercise
of this Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

      4. Notice of Adjustments. Whenever the number of Shares purchasable
hereunder or the Exercise Price thereof shall be adjusted pursuant to Section 3
hereof, the Company shall provide notice to the Holder setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and the number
and class of shares which may be purchased thereafter and the Exercise Price
therefor after giving effect to such adjustment.

      5. Fractional Shares. This Warrant may not be exercised for fractional
shares. In lieu of fractional shares the Company shall make a cash payment
therefor based upon the Exercise Price then in effect and the fair market value
of the shares then obtaining (calculated in accordance with Section 1(c) hereof
as if the shares were the Shares referred to in such Section).

      6. Representations of the Company. The Company represents that all
corporate actions on the part of the Company, its officers, directors and
shareholders necessary for the sale and issuance of the Shares pursuant hereto
and the performance of the Company's obligations hereunder were taken prior to
and are effective as of the effective date of this Warrant.

      7. Representations and Warranties by the Holder. The Holder represents and
warrants to the Company as follows:

      (a) This Warrant and the Shares issuable upon exercise thereof are being
acquired for its own account, for investment and not with a view to, or for
resale in connection with, any distribution or public offering thereof within
the meaning of the Securities Act of 1933, as amended (the "Act"). Upon exercise
of this Warrant, the Holder shall, if so requested by the Company, confirm in
writing, in a form satisfactory to the Company, that the securities issuable
upon exercise of this Warrant are being acquired for investment and not with a
view toward distribution or resale.

                                       4
<PAGE>

      (b) The Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by the Holder indefinitely,
and that the Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration.

      (c) The Holder has such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of the purchase of
this Warrant and the Shares purchasable pursuant to the terms of this Warrant
and of protecting its interests in connection therewith.

      (d) The Holder is able to bear the economic risk of the purchase of the
Shares pursuant to the terms of this Warrant.

      (e) The Holder is an "accredited investor" as defined in the Act.

      8. Restrictive Legend.

      The Shares (unless registered under the Act) shall be stamped or imprinted
with a legend in substantially the following form:

      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED. SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
SUCH REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL
REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM
THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT.

      9. Restrictions Upon Transfer and Removal of Legend.

      (a) The Company need not register a transfer of this Warrant or Shares
bearing the restrictive legend set forth in Section 8 hereof, unless the
conditions specified in such legend are satisfied. The Company may also instruct
its transfer agent not to register the transfer of the Shares, unless one of the
conditions specified in the legend referred to in Section 8 hereof is satisfied.

      (b) Notwithstanding the provisions of paragraph (a) above, no opinion of
counsel shall be necessary for a transfer without consideration by any holder
(i) if such holder is a partnership, to a partner or retired partner of such
partnership who retires after the date hereof or to the estate of any such
partner or retired partner, or (ii) if such holder is a corporation, to a
shareholder of such corporation, or to any other corporation under common
control, direct or indirect, with such holder.

Warrant shall have been exercised and the Shares purchasable upon the exercise

      3. Stock Subject to Options.

            (a) Number of Shares Reserved. The maximum number of shares that may
      be optioned and sold under the Plan is the greater of (i) five million
      (5,000,000) shares of Common Stock of the Company, subject to adjustment
      as provided in Section 6(j), or (ii) twenty percent (20%) of the total
      number of shares of Common Stock that would be outstanding if each class
      of the Company's stock (including each class of preferred stock) were
      converted into shares of Common Stock. During the term of this Plan, the
      Company shall at all times reserve and keep available a sufficient number
      of authorized but unissued shares of its Common Stock to satisfy the
      requirements of the Plan. Notwithstanding the foregoing, in no event shall
      the number of shares of Common Stock which may be issued upon the exercise
      of Incentive Stock Options exceed five million (5,000,000) shares, subject
      to the adjustment provided in Section 6(j).

            (b) Expired Options. If any outstanding Option expires or becomes
      unexercisable for any reason without having been exercised in full, the
      shares of Common Stock allocable to the unexercised portion of such Option
      will again become available for other Option grants.

      4. Administration of the Plan.

            (a) The Committee. The Plan is administered by the Board directly,
      acting as a Committee of the whole, or if the Board elects, by a separate
      Committee appointed by the Board for that purpose and consisting of at
      least two Board members, all of who shall be Non-Employee Directors. All
      references in the Plan to the "Committee" are to such separate Committee,
      if any is established, or if none is then in existence, then to the Board
      as a whole. Once appointed, any such Committee shall continue to serve
      until otherwise directed by the Board. From time to time the Board may
      increase the size of the Committee and appoint additional members thereto,
      remove members (with or without cause), appoint new members in
      substitution therefor, and fill vacancies (however caused). At all times,
      the Board has the power to remove all members of the Committee and
      thereafter to directly administer the Plan as a Committee of the whole.

            (b) Meetings; Reports. The Committee shall select one of its members
      as chairman, and hold meetings at such times and places as the chairman or
      a majority of the Committee may determine. All actions of the Committee
      shall be either by:

                  (1) a majority vote of the members of the full Committee at a
            meeting of the Committee, or

                  (2) by unanimous written consent of all members of the full
            Committee without a meeting.

      At least annually, the Committee shall present a written report to the
      Board indicating the persons to whom Options have been granted since the
      date of the last such report, and in each case the date or dates of
      Options granted, the number of shares optioned, and the Option price per
      share.

            (c) Powers of the Committee. Subject to all provisions and
      limitations of the Plan, the Committee has the authority and discretion
      to:

                  (1) Determine the persons to whom Options are to be granted,
            the times of grant, the number of shares to be represented by each
            Option, and the vesting schedule of the Options;

                  (2) Interpret the Plan (but only to the extent not contrary to
            the express provisions of the Plan);

                  (3) Authorize any person or persons to execute and deliver
            Stock Option Agreements or to take any other actions deemed by the
            Committee to be necessary or appropriate to effectuate the grant of
            Options by the Committee; and

                                     - 4 -
<PAGE>

                  (4) Make all other determinations and take all other actions
            that the Committee deems necessary or appropriate to administer the
            Plan in accordance with its terms and conditions.

            (d) Final Authority; Limitation of Liability. The Committee's
      decisions, determinations and interpretations are final and binding on all
      persons, including all Optionees and any other holders or persons
      interested in any Options, unless otherwise expressly determined by a vote
      of the majority of the entire Board. No member of the Committee or of the
      Board may be held liable for any action or determination made in good
      faith with respect to the Plan or any Option.

            (e) Approval of Grants to Committee Composed of Non-Employee
      Directors. Any grant of Options to a member of a Committee composed of
      Non-Employee Directors shall be approved of by the full Board of
      Directors. The full Board of Directors shall then be construed as the
      Committee for purposes of administering the Plan with respect to such
      Options.

      5. Eligibility; Limitation of Rights. The grant of Options under the Plan
is entirely discretionary with the Committee, and the adoption of the Plan does
not confer upon any person any right to receive any Option or Options unless and
until granted by the Committee, in its sole discretion. Neither the adoption of
the Plan nor the grant of any Options to any person or Optionee will confer any
right to continued employment, nor shall the same interfere in any way with that
person's right or that of the Company (or any Parent or Subsidiary) to terminate
the person's employment at any time.

      6. Option Terms; Conditions. All Option grants under the Plan shall be (i)
approved by the Committee, and (ii) documented by a Stock Option Agreement in
such form as the Committee approves from time to time. All Stock Option
Agreements shall comply with, and are subject to the following terms and
conditions:

            (a) Number of Shares. Each Stock Option Agreement shall state the
      number of shares subject to Option. Any number of Options may be granted
      to a single eligible person at any time and from time to time, subject to
      the maximum number of Options available for granting pursuant to this
      Plan.

            (b) Exercise Price. The exercise price ("Exercise Price") of the
      Option shall be determined by the Committee subject to its own discretion,
      it being understood that the price so determined by the Committee may vary
      from one Eligible Participant to another. The Stock Option Agreement shall
      state the price per share of Common Stock at which the Option is
      exercisable. The Exercise Price shall be fixed by the Committee at what
      ever price the Committee may determine in the exercise of its sole
      discretion, provided that:

                  (1) The per share Exercise Price for any Option granted to an
            Optionee shall not be less than the fair market value per share of
            the Common Stock on the Date of Grant thereof as reasonably
            determined by the Committee;

                                     - 5 -
<PAGE>

                  (2) With respect to Incentive Stock Options granted to
            greater-than-ten-percent shareholders of the Company or the Parent
            of the Company, the exercise price per share shall not be less than
            one hundred ten percent (110%) of the fair market value per share of
            the Common Stock on the Date of Grant thereof as reasonably
            determined by the Committee;

                  (3) The Options granted in substitution for outstanding
            options of another corporation in connection with the merger,
            consolidation, acquisition of property or stock or other
            reorganization involving such other corporation and the Company or
            any subsidiary of the Company may be granted with an Exercise Price
            equal to the exercise price for the substituted option of the other
            corporation, subject to any adjustment consistent with the terms of
            the transaction pursuant to which the substituted option is to be
            issued; and

                  (4) The Incentive Stock Options granted to the Employee to the
            extent that the fair market value of the Shares which are
            exercisable for the first time by any Optionee during any calendar
            year exceeds $100,000, such Options shall be treated as Options
            which are not Incentive Stock Options.

            (c) Consideration; Manner of Exercise. The Exercise Price shall be
      payable either (i) in U.S. dollars, or (ii) if approved by the Board, in
      other consideration, including, without limitation, Common Stock of the
      Company or other property. An Option is deemed to be exercised when
      written notice of exercise has been given to the Company in accordance
      with the terms of the Option by the person entitled to exercise the
      Option, together with full payment of the Exercise Price for the shares of
      Optioned Stock subject to said notice.

            (d) Term of Option. Under no circumstances may an Option granted
      under the Plan be exercisable after the expiration of ten (10) years from
      the date on which such Option is granted. The term in which each Option
      may be exercised ("Exercise Period") shall be determined by the Committee
      in its discretion, and set forth in the Stock Option Agreement.

            (e) Date of Grant; Vesting; Holdings Period. The Date of Grant of an
      Option, for all purposes, is the date the Committee makes the
      determination granting the Option or such future date as may be set forth
      in the Stock Option Agreement. Shares of Common Stock obtained upon the
      exercise of any Option may not be sold by any Optionee that is subject to
      Section 16 of the 1934 Act until six (6) months have elapsed since the
      Date of Grant of the Option. The vesting schedule for all Options shall be
      determined by the Committee in its discretion and shall be stated in the
      Stock Option Agreement.

            (f) Death of Optionee. Unless otherwise stated in the Stock Option
      Agreement, in the event of the death during the Exercise Period of an
      Optionee who was then an Employee or Independent Contractor, the unvested
      portion of the Option held by such Optionee shall terminate on the date of
      the Optionee's death. The unexercised and vested portion of the Option
      that is an Incentive Stock Option may be exercised by the Optionee's
      estate within one (1) year of the death of the Optionee, whereafter, the
      remaining unexercised portion of such Option shall terminate. The
      unexercised and vested portion of the deceased Optionee's Option that is a
      Non-Qualified Option may be exercised until the last day of the fifteenth
      (15th) calendar month following the month in which death of the Optionee
      occurs, whereafter, the remaining unexercised portion of such Option shall
      terminate. Under these circumstances, the Option will be exercisable by
      the Optionee's estate, or by such person or persons who have acquired the
      right to exercise the Option by bequest or by inheritance or by reason of
      the Optionee's death. Any Optioned Stock subject to the unvested portion
      of an Option shall revert back into the pool of Common Stock available for
      issuance under the Plan and shall be available for grant pursuant to a new
      Option.

<PAGE>

                  (g) Disability of Optionee. Unless otherwise stated in the
            Stock Option Agreement, if an Optionee's status as an Employee or
            Independent Contractor is terminated at any time during the Exercise
            Period by reason of the disability of the Optionee within the
            meaning of Section 22(e)(3) of the Code, the unvested portion of the
            Option held by such Optionee shall terminate on the date of
            termination of the Optionee's employment or status as an Independent
            Contractor (such date being the "Date of Disability"). The
            unexercised and vested portion of the Option that is an Incentive
            Stock Option may be exercised by the Optionee within one (1) year of
            the Date of Disability, whereafter, the remaining unexercised
            portion of such Option shall terminate. The unexercised and vested
            portion of the Option that is a Non-Qualified Stock Option may be
            exercised by the Optionee until the last day of the fifteenth (15th)
            calendar month following the month in which the Date of Disability
            occurs, whereafter, the remaining unexercised portion of such Option
            shall terminate. Any Optioned Stock subject to the unvested portion
            of an Option shall revert back into the pool of Common Stock
            available for issuance under the Plan and shall be available for
            grant pursuant to a new Option.

                  (h) Termination of Status as an Employee or Independent
            Contractor.

                        (1) Unless otherwise stated in the Stock Option
                  Agreement, if an Optionee's status as an Employee or
                  Independent Contractor is terminated by the Optionee at any
                  time after the Date of Grant for any reason other than death
                  or disability, as provided in Sections 6(f) and 6(g) hereof,
                  then the unexercised and vested portion of an Option shall
                  terminate ninety (90) days following the date on which
                  Optionee's termination of status as an Employee or Independent
                  Contractor occurs, as applicable. Any Optioned Stock subject
                  to the unvested portion of an Option shall revert back into
                  the pool of Common Stock available for issuance under the Plan
                  and shall be available for grant pursuant to a new Option.

                        (2) Unless otherwise stated in the Stock Option
                  Agreement, if an Optionee's status as an Employee or
                  Independent Contractor is terminated by the Company, and such
                  termination is for "cause" (such termination being referred to
                  as a "Termination for Cause") at any time after the grant of
                  an Option by the Company, then all Options (both vested and
                  unvested) shall terminate on the date of termination of
                  Optionee's status as an Employee or Independent Contractor, as
                  applicable, and any Optioned Stock subject to such Options
                  shall revert back into the pool of Common Stock available for
                  issuance under the Plan and shall be available for grant
                  pursuant to a new Option. An Optionee's status as an Employee
                  or Independent Contractor shall be deemed to have been
                  terminated for "cause" if such termination is determined, in
                  the sole discretion of the Committee, to have resulted from
                  any of the following: (i) an act or omission by the Optionee
                  constituting active and deliberate dishonesty, as established
                  by a final judgment or actual receipt of an improper benefit
                  or profit in money, property or services; (ii) the Optionee's
                  continuous failure or the Optionee's refusal to perform his,
                  her or its duties assigned to such Optionee by the Company (or
                  to perform according to the reasonable expectations and
                  standards set by the Committee and/or management consistent
                  with Optionee's title and position) after receipt of notice of
                  such failure from the Company specifying how the Optionee has
                  so failed to perform and the provision of a reasonable
                  opportunity to cure such performance as determined by the
                  Committee in its sole discretion; (iii) material dishonesty
                  related to such person's employment or services as an Employee
                  or Independent Contractor to the Company; (iv) commission of a
                  felony or other act involving moral turpitude; or (v)
                  misappropriation of a material business opportunity of the
                  Company. An Optionee's attempted resignation to avoid a
                  Termination for Cause shall not be effective, if the conduct
                  that ultimately results in the Termination for Cause occurred
                  prior to the attempted resignation.

                                     - 7 -
<PAGE>

            (i) Nontransferability of Options. Except as authorized by the
      Committee in writing, no Option granted under the Plan may be sold,
      pledged, assigned, hypothecated, transferred, or disposed of in any manner
      other than by will or by the laws of descent or distribution and may be
      exercised, during the lifetime of the Optionee, only by the Optionee.

            (j) Adjustments Upon Changes in Capitalization. Subject to any
      required action by the shareholders of the Company, the number of shares
      of Common Stock covered by each outstanding Option, the number of shares
      of Common Stock available for grant of additional Options, and the price
      per share of Common Stock specified in each outstanding Option, shall be
      proportionately adjusted for any increase or decrease in the number of
      issued shares of Common Stock resulting from any stock split or other
      subdivision or consolidation of shares, the payment of any stock dividend
      (but only on the Common Stock) or any other increase or decrease in the
      number of such shares of Common Stock effected without receipt of
      consideration by the Company; provided, however, that conversion of any
      convertible securities of the Company will not be deemed to have been
      "effected without receipt of consideration."

            Any adjustments as a result of a change in the Company's
      capitalization will be made by the Committee, whose determination in that
      respect is final, binding and conclusive. Except as otherwise expressly
      provided in this Section 6(j), no Optionee shall have any rights by reason
      of any stock split or the payment of any stock dividend or any other
      increase or decrease in the number of shares of Common Stock. Except as
      otherwise expressly provided in this Section 6(j), any issue by the
      Company of shares of stock of any class, or securities convertible into
      shares of stock of any class, shall not affect the number of shares or
      price of Common Stock subject to any Options, and no adjustments in
      Options shall be made by reason thereof. The grant of an Option under the
      Plan does not in any way affect the right or power of the Company to make
      adjustments, reclassifications, reorganizations or changes of its capital
      or business structure.

            (k) Conditions Upon Issuance of Shares. Shares of Common Stock may
      not be issued with respect to an Option granted under the Plan unless the
      exercise of the Option and the issuance and delivery of such shares
      pursuant thereto complies with all applicable provisions of law,
      including, applicable federal and state securities laws.

                                     - 8 -
<PAGE>

            As a condition to the exercise of an Option, the Company may require
      the person exercising such Option to represent and warrant at the time of
      exercise that the shares of Common Stock are being purchased only for
      investment and without any present intention to sell or distribute such
      Common Stock if, in the opinion of counsel for the Company, such a
      representation is required by any relevant provisions of law.

            (l) Occurrence of Change of Control Event. Unless otherwise stated
      in the Stock Option Agreement or as otherwise determined by the Committee,
      upon the occurrence of a Change of Control Event, the Optionee shall be
      vested as to that portion of an Option that has previously vested and /or
      that would have become vested to the Optionee within the twelve (12) month
      period after the occurrence of the Change of Control Event had such Change
      of Control Event not occurred (assuming the Optionee had maintained a
      Continuous Relationship with the Company during such period). The
      non-vested portion of the Option (after taking into account the provisions
      of the immediately preceding sentence) shall terminate upon the occurrence
      of the Change of Control Event. With respect to a Change of Control Event,
      the Committee may, in its sole discretion, adopt a resolution terminating
      the Options granted by the Company as of a date fixed by the Committee
      ("Change of Control Termination Date") and that provides each Optionee the
      right to exercise the vested portion of his, her or its Option (including
      that portion of an Option which vests as a result of the occurrence of the
      Change of Control Event) on or before the Change of Control Termination
      Date. In the event the Committee adopts such a resolution terminating the
      Options as provided in the preceding sentence, the Company shall notify
      all Optionees of such termination of the Options and provide such Optionee
      a period of time, as determined by the Committee, to so exercise the
      vested portion of his, her or its Option on or prior to the Change of
      Control Termination Date. With respect to any Optionee that so exercises
      the vested portion of his, her or its Option on or prior to the Change of
      Control Termination Date, the Company may, in lieu of the issuance of
      Optioned Stock to the Optionee, pay such Optionee the excess of the amount
      received or to be received for the Optioned Stock over the amount that is
      to be paid to the Company by the Optionee upon the exercise of the vested
      portion of the Option, reduced by the amount of any applicable withholding
      taxes.

            (m) Substitute Stock Options. In connection with the acquisition or
      proposed acquisition by the Company or any Subsidiary or Parent of the
      Company (whether by merger, acquisition of stock or assets, or other
      reorganization transaction) of a business that has granted stock options
      to any of its employees, the Committee is authorized to issue, in
      substitution of any such unexercised stock options, a new Option under
      this Plan or any successor plan (whether created by the Company or its
      acquirer) which confers upon the Optionee substantially the same benefits
      as the old option.

            (n) Tax Compliance. The Company, in its sole discretion, may take
      any actions that it reasonably believes to be required in order to comply
      with any local, state, or federal tax laws relating to the reporting or
      withholdings of taxes attributable to the grant or exercise of any Option
      or the disposition of any shares of Optioned Stock issued upon exercise of
      an Option, including, but not limited to: (i) withholding from any
      Optionee exercising an Option all or any portion of the Optioned Stock
      issuable to such Optionee upon the exercise of such Option, until such
      time as the Optionee reimburses the Company for the amount required to be
      withheld under applicable tax laws with respect to such exercise of the
      Option; (ii) withholding and canceling that number of shares of Optioned
      Stock issuable to the Optionee upon the exercise of an Option having a
      fair market value equal to the amount necessary to reimburse Company for
      the tax required to be withheld by the Company under applicable tax laws;
      and (iii) withholdings from any form of compensation or other amount due
      to an Optionee or holder of shares of Optioned Stock issued upon exercise
      of an Option any amount required to be withheld by Company under
      applicable tax laws. Withholdings or reporting is considered required for
      purposes of this Section 6(n), if any tax deduction or other favorable tax
      treatment available to Company is conditioned upon such reporting or
      withholdings.

            (o) Incentive Stock Options. If any provision of this Plan or any
      Option designated by the Committee as an Incentive Stock Option shall be
      held not to comply with requirements necessary to entitle such Option to
      such tax treatment, then (i) such provision shall be deemed to have
      contained from the outset such language as shall be necessary to entitle
      the Option to the tax treatment afforded under Section 422 of the Code,
      and (ii) all other provisions of this Plan and the Stock Option Agreement
      shall remain in full force and effect. If any agreement covering an Option
      designated by the Committee to be an Incentive Stock Option under this
      Plan shall not explicitly include any terms required to entitle such
      Incentive Stock Option to the tax treatment afforded by Section 422 of the
      Code, all such terms shall be deemed implicit in the designation of such
      Option and the Option shall be deemed to have been granted subject to all
      such terms.

            (p) Other Provisions. Stock Option Agreements executed under the
      Plan may contain such other provisions as the Committee deems advisable,
      provided that they are not inconsistent with any of the other terms and
      conditions of the Plan or applicable laws.

      7. Securities Law Restrictions. The Company shall not be obligated to
issue any stock certificates evidencing a transfer of Optioned Stock upon the
exercise of an Option until, in the opinion of the Company and its counsel, such
transfer and issuance of stock certificates will not involve any violation of
applicable federal and state securities laws, the rules and regulations
promulgated thereunder and the requirements of any stock exchange upon which the
Company's Common Stock may then be listed. Acceptance of an Option by an
Optionee shall constitute the Optionee's agreement (binding on any person who
succeeds to the Optionee's rights and obligations under the Stock Option
Agreement by reason of the Optionee's death) that any Optioned Stock purchased
pursuant to the exercise of the Option shall be acquired for the Optionee's own
account and not with a view to distribution and that each notice of the exercise
of any portion of the Option shall be accompanied by a written representation
and covenant signed by the Optionee, in such form as may be specified by the
Company, confirming such agreement and containing such other provisions as may
be prescribed by the Company. The Committee may, at its election, release an
Optionee from the Optionee's agreement to take for the Optionee's own account
and not with a view to distribution of the shares of Optioned Stock purchased
upon exercise of an Option if, in the opinion of the Committee, such covenant
ceases to be necessary for compliance with the applicable federal and state
securities laws (including the rules and regulations promulgated thereunder).

      If the Optioned Stock purchased upon exercise of an Option are not covered
by an effective registration statement under the Securities Act, the Company may
place the following legend (or a legend which is substantially similar to the
following legend) upon, and issue appropriate stock transfer instructions with
respect to, the certificate or certificates representing the Optioned Stock
issued pursuant to an exercise of the Option:

      "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
      APPLICABLE STATE SECURITIES LAWS (THE STATE LAWS"), AND SUCH SHARES MAY
      NOT BE TRANSFERRED UNLESS (A) A REGISTRATION STATEMENT UNDER THE
      SECURITIES ACT AND APPLICABLE STATE LAWS COVERING SUCH TRANSFER IS THEN IN
      EFFECT; OR (B) AN OPINION OF COUNSEL, SATISFACTORY TO THE CORPORATION, HAS
      BEEN FURNISHED STATING THAT SUCH TRANSFER IS EXEMPT FROM THE REGISTRATION
      REQUIREMENTS OF THE SECURITIES ACT AND APPLICABLE STATE LAWS."

      8. Listing or Registration of Stock. Each Option is subject to the
requirement that, if at any time the Board shall determine, in its sole
discretion, that the listing, registration or qualification of the Optioned
Stock upon any securities exchange or under any state or federal law, or the
consent or approval of any government regulatory body, is necessary or desirable
as a condition of, or in connection with, the granting or exercise of the Option
or the issuance or purchase of the Optioned Stock pursuant to the Option, the
Option may not be exercised in whole or in part until such listing,
registration, qualification, consent or approval shall have been effected or
obtained free of any conditions not acceptable to the Board. The Company shall
be under no obligation to effect or obtain any such listing, registration,
qualification, consent or approval, if the Board shall determine, in its
discretion, that such action would not be in the best interests of the Company.
The Company shall not be liable for damages due to a delay in the delivery or
issuance of any stock certificates for any reason whatsoever, including, but not
limited to, a delay caused by listing, registration or qualification of the
shares of Common Stock subject to an Option under any securities exchange or
under any federal or state law, or by the effecting or obtaining of any consent
or approval of any governmental body with respect to the granting or exercise of
the Option or the issuance or purchase of Optioned Stock pursuant to an Option.

      9. Modification of Options. At any time, and from time to time, the Board
may provide for the modification, extension or renewal of any outstanding
Option, provided that no such modification, extension or renewal shall impair
the Option in any respect without the consent of the holder of the Option.

      10. Term of the Plan. The Plan is effective on the date of adoption of the
Plan by the Board. Unless sooner terminated as provided in Section 11, the Plan
will terminate on the tenth (10th) anniversary of its effective date. Options
may be granted at any time after the effective date and prior to the date of
termination of the Plan.

                                     - 11 -

      11. Amendment; Early Termination. The Board may terminate or amend the
Plan at any time and in such respects as it deems advisable, although no
amendment or termination would affect any previously-granted Options, which
would remain in full force and effect notwithstanding any amendment or
termination of the Plan. Shareholder approval of any amendments to the Plan
shall be obtained whenever required by applicable law(s) or stock market
regulations.

      12. Inability to Obtain Authority. The inability of the Company to obtain
authority to issue and sell shares under the Plan from any regulatory body
having jurisdiction, which authority is considered by the Company's counsel to
be necessary to the lawful issuance and sale of the shares under the Plan, will
relieve the Company of any liability in respect of the failure to issue or sell
those shares.

      13. Shareholder Ratification. The adoption of the Plan shall be subject to
ratification by the affirmative vote of the holders of a majority of the shares
of Common Stock represented in person or by proxy at a duly convened meeting of
the shareholders of the Company, which ratification shall occur within twelve
(12) months before or after the date of adoption of the Plan by the Board.

      14 Notices. Every direction, revocation or notice authorized or required
by the Plan shall be deemed delivered to the Company (i) on the date it is
personally delivered to the Secretary of the Company at its principal executive
offices, (ii) three (3) business days after it is sent by registered or
certified mail, postage prepaid, addressed to the Secretary at such offices, or
(iii) one (1) business day after it is sent by a reputable overnight courier
service, addressed to the Secretary at such office, and shall be deemed
delivered to an Optionee (i) on the date it is personally delivered to him or
her, (ii) on the date of mailing if it is sent by registered or certified mail,
postage prepaid, addressed to him or her at the last address shown for him or
her on the records of the Company, or (iii) one (1) business day after it is
sent by reputable overnight courier service, addressed to him or her at the last
address shown for him or her on the records of the Company. If the effective
date as provided above is not a business day, the effective date shall be the
next regular business day. The Company or an Optionee may, at any time, notify
the other as provided above of a new address for service of notice upon the
party.

      15. Applicable Law. All questions pertaining to the validity, construction
and administration of the Plan and Stock Options granted hereunder shall be
determined in conformity with the laws of the State of Illinois.
