                        UPGRADE INTERNATIONAL CORPORATION
                             (A FLORIDA CORPORATION)

                             2000 STOCK OPTION PLAN

1. Purpose. The purpose of the 2000 Stock Option Plan (the "Plan") is to provide
a means by which Upgrade International Corporation, a Florida corporation, (the
"Company") may attract, reward, and retain services or advice of current or
future employees, officers, directors, and agents of the Company and to provide
added incentives to them by encouraging stock ownership in the Company.

2. Administration. This Plan shall be administered by the Board of Directors of
the Company (the "Board") or, if the Board shall authorize a committee to
administer this Plan, by such committee to the extent so authorized; provided,
however, that only the Board of Directors may suspend, amend or terminate this
Plan as provided in Section 13, and provided further that a committee that
includes officers of the Company shall not be permitted to grant options to
persons who are officers of the company. The administrator of this Plan is
referred to as the "Plan Administrator."

        2.1 Procedures. The Board of Directors shall designate one member of the
Plan Administrator as chairman. The Plan Administrator may hold meetings at such
times and places as it shall determine. The acts of a majority of the members of
the Plan Administrator present at meetings at which a quorum exits, or acts
approved in writing by all Plan Administrator members, shall constitute valid
acts of the Plan Administrator.

        2.2 Powers. Subject to the specific provisions of this Plan, the Plan
Administrator shall have the authority, in its discretion: (a) to grant the
stock options described in Section 5, including Incentive Stock Options and
Non-Qualified Stock Options, and to designate each option granted as an
Incentive Stock Option or a Non-Qualified Stock Option; (b) to determine, in
accordance with Section 5.1(f) of this Plan, the fair market value of the shares
of Common Stock subject to options; (c) to determine the exercise price per
share of options; (d) to determine the Optionees to whom, and the time or times
at which, options shall be granted and the number of shares of common stock to
be represented by each option; (e) to interpret this Plan; (f) to prescribe,
amend and rescind rules and regulations relating to this Plan; (g) to determine
the terms and provisions of each option granted (which need not be identical)
and, with the consent of the Optionee, modify or amend each option; (h) to
reduce the exercise price per share of outstanding and unexercised options; (i)
to defer, with the consent of the Optionee, or to accelerate the exercise date
of any option; (j) to waive or modify any term or provisions contained in any
option applicable to the underlying shares of Common Stock; (k) to authorize any
person to execute on behalf of the Company any instrument required to effectuate
the grant of an option previously granted by the Plan Administrator; and (l) to
make all other determinations deemed necessary or advisable for the
administration of

this Plan. The interpretation and construction by the Plan Administrator of any
terms or provisions of this Plan, any option issued hereunder or of any rule or
regulation promulgated in connection herewith and all actions taken by the Plan
Administrator shall be conclusive and binding on all interested parties. The
Plan Administrator may delegate administrative functions to individuals who are
officers or employees of the Company.

        2.3 Limited Liability. No member of the Board of Directors or the Plan
Administrator or officer of the Company shall be liable for any action or
inaction of the entity or body, or another person or, except in circumstances
involving bad faith, of himself or herself. Subject only to compliance with the
explicit provisions hereof, the Board of Directors and Plan Administrator may
act in their absolute discretion in all matters related to the Plan.

        2.4 Securities Exchange Act of 1934. At any time that the Company has a
class of securities registered pursuant to Section 12 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), this Plan shall be administered in
accordance with Rule 16b-3 adopted under the Exchange Act and Section 162(m) of
the Internal Revenue Code of 1986, as amended, and the regulations, proposed and
final, thereunder, as all may be amended from time to time, and each member of
the Plan Administrator shall be a "disinterested director" and an "outside
director" with the meaning of such Rule 16b-3 and Section 162(m), respectively.

3. Stock Subject to This Plan. Subject to adjustment as provided below and in
Section 11 hereof, the stock subject to this Plan shall be the Company's common
stock (the "Common Stock"), and the total number of shares of Common Stock to be
delivered on the exercise of all options granted under this Plan shall not
exceed 800,000 shares as such Common Stock was constituted on the Effective Date
of this Plan (as defined in Section 15 hereof). If any option granted under this
Plan expires, is surrendered, exchanged for another option, canceled or
terminated for any reason without having been exercised in full, the unpurchased
shares subject thereto shall again be available for purposes of this Plan,
including for replacement options that may be granted in exchange for such
surrendered, canceled or terminated options. Shares issued on exercise of
options granted under this Plan may be subject to restrictions on transfer,
repurchase rights or other restrictions as determined by the Plan Administrator.

4. Eligibility.

        4.1 Optionees. The Plan Administrator may award options to any current
or future employee, officer, agent, consultant or director of the Company or its
subsidiaries. Any party to whom an option is granted under this Plan is referred
to as an "Optionee."

        4.2 Subsidiaries. As used in this Plan, the term "subsidiary" of a
company shall include any corporation in which such company owns, directly or
indirectly, at the

Page -2-
<PAGE>   3

time of the grant of an option hereunder, stock having 50% or more of the total
combined voting power of all classes of stock thereof.

5. Awards. The Plan Administrator, from time to time, may take the following
actions, separately or in combination, under this Plan: (a) grant Incentive
Stock Options, as defined in Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"), to any employee of the Company or its subsidiaries, as
provided in Section 5.1 of this Plan; (b) grant options other than Incentive
Stock Options ("Non-Qualified Stock Options"), as provided in Section 5.2 of
this Plan; (c) grant options to officers, employees and others in foreign
jurisdictions, as provided in Section 7 of this Plan; and (d) grant options in
certain acquisition transactions, as provided in Section 8 of this Plan. No
employee may be granted options to acquire more than 100,000 shares in any
fiscal year of the Company.

        5.1 Incentive Stock Options. Incentive Stock Options shall be subject to
the following terms and conditions:

            (a) Incentive Stock Options may be granted under this Plan only to
employees of the company or its subsidiaries, including employees who are
directors.

            (b) No employee may be granted Incentive Stock Options under this
Plan to the extent that the aggregate fair market value, on the date of grant,
of the Common Stock with respect to which Incentive Stock Options are
exercisable for the first time by that employee during any calendar year, under
this Plan and under any other incentive stock option plan (within the meaning of
Section 422 of the Code) of the Company or any subsidiary, exceeds $100,000. To
the extent that any option designated as an Incentive Stock Option exceeds the
$100,000 limit, such option shall be treated as a Non-Qualified Stock Option. In
making this determination, options shall be taken into account in the order in
which they were granted, and the fair market value of the shares of Common Stock
shall be determined as of the time that the option with respect to such shares
was granted.

            (c) An Incentive Stock Option may be granted under this Plan to an
employee possessing more than 10% of the total combined voting power of all
classes of stock of the Company (as determined pursuant to the attribution rules
contained in Section 424(d) of the Code) only if the exercise price is at least
110% of the fair market value of the Common Stock subject to the option on the
date the option is granted, as described in Section 5.1(f) of this Plan, and
only if the option by its terms is not exercisable after the expiration of five
years from the date it is granted.

            (d) Except as provided in Section 5.5 of this Plan, no Incentive
Stock Option granted under this Plan may be exercised unless at the time of such
exercise the

Page -3-
<PAGE>   4

Optionee is employed by the Company or any subsidiary of the company and the
Optionee has been so employed continuously since the date such option was
granted.

            (e) Subject to Sections 5.1.(c) and 5.1.(d) of this Plan, Incentive
Stock Options granted under this Plan shall continue in effect for the period
fixed by the Plan Administrator, except that no Incentive Stock Option shall be
exercisable after ten years from the date it is granted.

            (f) The exercise price shall not be less than 100% of the fair
market value of the shares of Common Stock covered by the Incentive Stock Option
at the date the option is granted. The fair market value of shares shall be the
closing price per share of the Common Stock on the date of grant as reported on
a securities quotation system or stock exchange. If such shares are not so
reported or listed, the Plan Administrator shall determine the fair market value
of the shares of Common Stock in its discretion.

            (g) The provisions of clauses (b) and (c) of this Section shall not
apply if either the applicable sections of the Code or the regulations
thereunder are amended so as to change or eliminate such limitations or to
permit appropriate modifications of those requirements by the Plan
Administrator.

        5.2 Non-Qualified Stock Options. Non-Qualified Stock Options shall be
subject to the following terms and conditions:

            (a) The exercise price may be more or less than or equal to the fair
market value of the shares of Common Stock covered by the Non-Qualified Stock
Option on the date the option is granted, and the exercise price may fluctuate
based on criteria determined by the Plan Administrator. The fair market value of
shares of Common Stock covered by a Non-Qualified Stock Option shall be
determined by the Plan Administrator, as described in Section 5.1(f).

            (b) Unless otherwise established by the Plan Administrator, any
Non-Qualified Stock Option shall terminate ten years after the date it is
granted.

        5.3 Vesting. To ensure that the Company will achieve the purposes of and
receive the benefits contemplated in this Plan, any option granted to any
Optionee hereunder shall be exercisable according to a vesting schedule or no
vesting schedule as established or determined by the Plan Administrator.

        5.4 Nontransferability. Options granted under this Plan and the rights
and privileges conferred hereby may not be transferred, assigned, pledged or
hypothecated in any manner (whether by operation of law or otherwise) other than
by will or by the applicable laws of descent and distribution, shall not be
subject to execution, attachment or similar process, and shall be exercisable

Page -4-
<PAGE>   5

during the Optionee's lifetime only by the Optionee. Any purported transfer or
assignment in violation of this provision shall be void.

        5.5 Termination of Options.

            (a) Generally. Unless otherwise determined by the Plan Administrator
or specified in the Optionee's Option Agreement, if the Optionee's employment or
service with the Company Terminates for any reason other than for cause,
resignation, retirement, disability or death, and unless by its terms the option
sooner terminates or expires, then the Optionee may exercise, for a three-month
period, that portion of the Optionee's option that was exercisable at the time
of such termination of employment or service (provided the conditions of Section
6.4 and any other conditions specified in the Option Agreement shall have been
met by the date of exercise of such option).

            (b) For Cause; Resignation.

                (i) If an Optionee is terminated for cause or resigns in lieu of
dismissal, any option granted hereunder shall be deemed to have terminated as of
the time of the first act that led or would have led to the termination for
cause or resignation in lieu of dismissal and such Optionee shall thereupon have
no right to purchase any shares of Common Stock pursuant to the exercise of such
option, and any such exercise shall be null and void. Termination for "cause"
shall include (i) the violation by the Optionee of any reasonable rule or policy
of the Board of Directors or the Optionee's superiors or the chief executive
officer or the chief operating officer of the Company that results in damage to
the Company or which, after notice to do so, the Optionee fails to correct
within a reasonable time; (ii) any willful misconduct or gross negligence by the
Optionee in the responsibilities assigned to him or her: (iii) any willful
failure to perform his or her job as required to meet the objectives of the
Company; (iv) any wrongful conduct of an Optionee that has an adverse impact on
the Company or that constitutes a misappropriation of the assets of the Company;
(v) unauthorized disclosure of confidential information; or (vi) the Optionee's
performing services for any other company or person that competes with the
Company while he or she is employed by or provides services to the Company,
without the written approval of the chief executive officer of the Company.
"Resignation in lieu of dismissal" shall mean a resignation by an Optionee of
employment with or service to the Company if (i) the Company has given prior
notice to such Optionee of its intent to dismiss the Optionee for circumstances
that constitute cause, or (ii) within two months of the Optionee's resignation,
the chief operating officer or the chief executive officer of the Company or the
Board of Directors determines, which determination shall be final and binding,
that such resignation was related to an act that would have led to a termination
for cause.

               (ii) If an Optionee resigns from the Company, the right of the
Optionee to exercise his or her option shall be suspended for a period of two
months from

Page -5-
<PAGE>   6

the date of resignation, unless the chief executive officer of the Company or
the Board of Directors determines otherwise in writing. Thereafter, unless there
is a determination that the Optionee resigned in lieu of dismissal, the option
may be exercised at any time before the earlier of (i) the expiration date of
the option (which shall have been similarly suspended) or (ii) the expiration of
three months after the date of resignation, for that portion of the Optionee's
option that was exercisable at the time of such resignation (provided the
conditions of Section 6.4 and any other conditions specified in the Option
Agreement shall have been met at the date of exercise of such option).

            (c) Retirement. Unless otherwise determined by the Plan
Administrator, if an Optionee's employment or service with the Company is
terminated with the company's approval for reasons of age, the Option may be
exercised at any time before the earlier of (a) the expiration date of the
option or (b) the expiration of three months after the date of such termination
of employment or service, for that portion of the Optionee's option that was
exercisable at the time of such termination of employment or service (provided
the conditions of Section 6.4 and any other conditions specified in the Option
Agreement shall have been met at the date of exercise of such option).

            (d) Disability. Unless otherwise determined by the Plan
Administrator, if an Optionee's employment or relationship with the Company
terminates because of a permanent or total disability (as defined in Section
22(e)(3) of the Code), the option may be exercised at any time before the
earlier of (a) the expiration date of the option or (b) the expiration of 12
months after the date of such termination, for up to the full number of shares
of Common Stock covered thereby, including any portion not yet vested (provided
the conditions of Section 6.4 and any other conditions specified in the Option
Agreement shall have been met by the date of exercise of such option).

            (e) Death. Unless otherwise determined by the Plan Administrator, in
the event of the death of an Optionee while employed by or providing service to
the Company, the option may be exercised at any time before the earlier of (a)
the expiration date of the option or (b) the expiration of 12 months after the
date of death by the person or persons to whom such Optionee's rights under the
option shall pass by the Optionee's will or by the applicable laws of descent
and distribution, for up to the full number of shares of Common Stock covered
thereby, including any portion not yet vested (provided the conditions of
Section 6.5 and any other conditions specified in the Option Agreement shall
have been met by the date of exercise of such option).

            (f) Extension of Exercise Period Applicable to Termination. The Plan
Administrator, at the time of grant or at any time thereafter, may extend the
one-month, three-month and 12-month exercise periods to any length of time not
longer than the original expiration date of the option, and may increase the
portion of an option that is exercisable, subject to such terms and conditions
as the Plan Administrator may determine; provided, that any extension of the
exercise period or other modification of an

Page -6-
<PAGE>   7

Incentive Stock Option shall be subject to the written agreement and
acknowledgment by the Optionee that the extension or modification disqualifies
the option as an Incentive Stock Option.

            (g) Failure to Exercise Option. To the extent that the option of any
deceased Optionee or of any optionee whose employment or service terminates is
not exercised within the applicable period, all rights to purchase shares of
Common Stock pursuant to such options shall cease and terminate.

            (h) Transfers; Leaves. For purposes of this Section 5.5, a transfer
of employment or other relationship between or among the Company and/or any
subsidiaries shall not be deemed to constitute a termination of employment or
other cessation of relationship with the Company or any of its subsidiaries. For
purposes of this Section 5.5, with respect to Incentive Stock Options,
employment shall be deemed to continue while the Optionee is on military leave,
sick leave or other bona fide leave of absence (as determined by the Plan
Administrator) in accordance with the policies of the Company.

6. Exercise.

        6.1 Procedure. Subject to the provisions of Section 5.3 above, each
option may be exercised in whole or in part; provided, however, that no fewer
than 100 shares (or the remaining shares then purchasable under the option, if
less than 100 shares) may be purchased on any exercise of any option granted
hereunder and that only whole shares will be issued pursuant to the exercise of
any option (the number of 100 shares shall not be changed by any transaction or
action described in Section 8 or Section 11 unless the Plan Administrator
determines that such a change is appropriate). Options shall be exercised by
delivery to the Secretary of the Company or his or her designated agent of
notice of the number of shares with respect to which the option is exercised,
together with payment in full of the exercise price and any applicable
withholding taxes.

        6.2 Payment. Payment of the option exercise price shall be made in full
when the notice of exercise of the option is delivered to the Secretary of the
Company or his or her designated agent and shall be in cash or bank certified or
cashier's check or through irrevocable instructions to a stock broker to deliver
the amount of sales proceeds necessary to pay the appropriate exercise price and
withholding tax obligations, all in accordance with applicable governmental
regulations, for the shares of Common Stock being purchased. The Plan
Administrator may determine at the time the option is granted for Incentive
Stock Options, or at an time before exercise for Non-Qualified Stock Options,
that additional forms of payment will be permitted.

        6.3 Withholding. Before the issuance of shares of Common Stock on the
exercise of an option, the Optionee shall pay to the Company the amount of any

Page -7-
<PAGE>   8

applicable federal, state or local tax withholding obligations. The Company may
withhold any distribution in whole or in part until the Company is so paid. The
Company shall have the right to withhold such amount from any other amounts due
or to become due from the Company to the Optionee, including salary (subject to
applicable law) or to retain and withhold a number of shares having a market
value not less than the amount of such taxes required to be withheld by the
Company to reimburse it for any such taxes and cancel (in whole or in part) any
such shares so withheld.

        6.4 Conditions Precedent to Exercise. The Plan Administrator may
establish conditions precedent to the exercise of any option, which shall be
described in the relevant Option Agreement.

7. Foreign Qualified Grants. Options under this Plan may be granted to officers
and employees of the Company and other person described in Section 4 who reside
in foreign jurisdictions as the Plan Administrator may determine form time to
time. The Board of Directors may adopt supplements to the Plan as needed to
comply with the applicable laws of such foreign jurisdictions and to give
Options favorable treatment under such laws; provided, however, that no award
shall be granted under any such supplement on terms more beneficial to such
Optionees than those permitted by this Plan.

8. Corporate Mergers, Acquisitions, Etc. The Plan Administrator may also grant
options under this Plan having terms, conditions and provisions that vary from
those specified in this Plan provided that such options are granted in
substitution for, or in connection with the assumption of, existing options
granted, awarded or issued by another corporation and assumed or otherwise
agreed to be provided for by the Company pursuant to or by reason of a
transaction involving a corporate merger, consolidation, acquisition of property
or stock, reorganization or liquidation to which the Company is a party.

9. Holding Period. Unless otherwise determined by the Plan Administrator, if a
person subject to Section 16 of the Exchange Act exercises an option within six
months of the date of grant of the option, the shares of Common Stock acquired
on exercise of the option may not be sold until six months after the date of
grant of the option.

10. Option Agreements. Options granted under this Plan shall be evidenced by
written stock option agreements (the "Option Agreements") that shall contain
such terms, conditions, limitations and restrictions as the Plan Administrator
shall deem advisable and that are consistent with this Plan. All Option
Agreements shall include or incorporate by reference the applicable terms and
conditions contained in this Plan.

11. Adjustments On Changes in Capitalization.

Page -8-
<PAGE>   9

        11.1 Stock Splits, Capital Stock Adjustments. The aggregate number and
class of shares for which options may be granted under this Plan, the number and
class of shares covered by each outstanding option and the exercise price per
share thereof (but not the total price), and each such option, shall all be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock of the Company resulting from a stock split, stock
dividend or consolidation of shares or any like capital stock adjustment.

        11.2 Effect of Merger, Sale of Assets, Liquidation or Dissolution.

            (a) Mergers, Sale of Assets, Other Transactions. In the event of a
merger, consolidation or plan of exchange to which the Company is a party or a
sale of all or substantially all of the Company's assets (each, a
"Transaction"), the Board of Directors, in its sole discretion and to the extent
possible under the structure of the Transaction, shall select one of the
following alternatives for treating outstanding options under this Plan:

                  (i) Outstanding options shall remain in effect in accordance
with their terms;

                  (ii) Outstanding options shall be converted into options to
purchase stock in the corporation that is the surviving or acquiring corporation
in the Transaction. The amount, type of securities subject thereto and exercise
price of the converted options shall be determined by the Board of Directors of
the Company, taking into account the relative values of the companies involved
in the Transaction and the exchange rate, if any, used in determining shares of
the surviving corporation to be issued to holders of shares of the Company.
Unless otherwise determined by the Board of Directors, the converted options
shall be vested only to the extent that the vesting requirements relating to
options granted hereunder have been satisfied;

                  (iii) The Board of Directors provides a period before the
consummation of the transaction during which outstanding options shall be
exercisable to the extent vested and, on the expiration of such period, all
unexercised options shall immediately terminate. The Board of Directors, in its
sole discretion, may accelerate the vesting of such options so that they are
exercisable in full during such period; or

                  (iv) The Board of Directors shall take such other action with
respect to outstanding options as the Board deems to be in the best interests of
the Company.

            (b) Liquidation; Dissolution. If the Company is liquidated or
dissolved, options shall be treated in accordance with Section 11.2(a)(iii).

Page -9-
<PAGE>   10

        11.3 Fractional Shares. If the number of shares covered by any option is
adjusted, any fractional shares resulting from such adjustment shall be
disregarded and each such option shall cover only the number of full shares
resulting from such adjustment.

        11.4 Determination of Board to Be Final. All adjustments under this
Section 11 shall be made by the Board of Directors, and its determination as to
what adjustments shall be made, and the extent thereof, shall be final, binding
and conclusive. Unless an Optionee agrees otherwise, any change or adjustment to
an Incentive Stock Option shall be made, if possible, in such a manner so as not
to constitute a "modification," as defined in Section 424(h) of the Code, and so
as not to cause the Optionee's Incentive Stock Option to fail to continue to
qualify as an Incentive Stock Option.

12. Securities Regulations.

        Shares of Common Stock shall not be issued with respect to an option
granted under this Plan unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, any applicable state
securities laws, the Securities Act of 1933, as amended, the Exchange Act, the
rules and regulations promulgated thereunder, applicable laws of foreign
countries and other jurisdictions and the requirements of any quotation service
or stock exchange on which the shares may then be listed, and shall be further
subject to the approval of counsel for the Company with respect to such
compliance, including the availability of an exemption from registration for the
issuance and sale of any shares hereunder. The inability of the Company to
obtain, from any regulatory body having jurisdiction, the authority deemed by
the Company's counsel to be necessary for the lawful issuance and sale of any
shares hereunder or the unavailability of an exemption from registration for the
issuance and sale of any shares hereunder shall relieve the Company of any
liability with respect of the nonissuance or sale of such shares as to which
such requisite authority shall not have been obtained.

        As a condition to the exercise of an option, the company may require the
Optionee to represent and warrant at the time of any such exercise that the
shares of Common Stock are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any relevant
provision of the aforementioned laws. The Company may place a stop-transfer
order against any shares of Common Stock on the official stock books and the
records of the Company, and a legend may be stamped on stock certificates to the
effect that the shares of Common Stock may not be pledged, sold or otherwise
transferred unless an opinion of counsel is provided (concurred in by counsel
for the Company) stating that such transfer is not in violation of any
applicable law or regulation. The Plan Administrator may also require such other
action or agreement by the Optionees as may from time to time be necessary to
comply with the

Page -10-
<PAGE>   11

federal and state securities laws. THE PROVISION SHALL NOT OBLIGATE THE COMPANY
TO UNDERTAKE REGISTRATION OF THE OPTIONS OR STOCK THEREUNDER.

        If any of the Company's capital stock of the same class as the Common
Stock subject to options granted hereunder is listed on a national securities
exchange, all shares of Common Stock issued hereunder if not previously listed
on such exchange shall be authorized by that exchange for listing thereon before
the issuance thereof.

13. Amendment and Termination.

        13.1 Plan. The Board of Directors may at any time suspend, amend or
terminate this Plan, provided that, except as set forth in Section 8, the
approval of the Company's shareholders is necessary within twelve months before
or after the adoption by the Board of Directors of any amendment that will:

             (a) increase the number of shares of Common Stock to be reserved
for the issuance of options under this Plan;

             (b) permit the granting of stock options to a class of persons
other than those now permitted to receive stock options under this Plan; or

             (c) require shareholder approval under applicable law, including
Section 16(b) of the Exchange Act.

        13.2 Options. Subject to the requirements of Section 422 of the Code
with respect to Incentive Stock Options and to the terms and conditions and
within the limitations of this Plan, the Plan Administrator may modify or amend
outstanding options granted under this Plan. The modification or amendment of an
outstanding option shall no, without the consent of the Optionee, impair or
diminish any of his or her rights or any of the obligations of the Company under
such option. Except as otherwise provided in this Plan, no outstanding option
shall be terminated without the consent of the Optionee. Unless the Optionee
agrees otherwise, any changes or adjustments made to outstanding Incentive Stock
Options granted under this Plan shall be made in such a manner so as not to
constitute a "modification," as defined in Section 425(h)of the Code, and so as
not to cause any Incentive Stock Option issued hereunder to fail to continue to
qualify as an Incentive Stock Option as defined in Section 422(b) of the Code.

        13.3 Automatic Termination. Unless sooner terminated by the Board of
Directors, this Plan shall terminate ten years from the date on which this Plan
is adopted by the Board. No option may be granted after such termination or
during any suspension of this Plan. The amendment or termination of this Plan
shall not, without the consent of

Page -11-
<PAGE>   12

the Optionee, alter or impair any rights or obligations under any option
theretofore granted under this Plan.

14. Miscellaneous.

        14.1 Time of Granting Options. The date of grant of an option shall, for
all purposes, be the date on which the Company completes the required corporate
action relating to the grant of an option; the execution of an Option Agreement
and the conditions to the exercise of an option shall not defer the date of
grant.

        14.2 No Status as Shareholder. Neither the Optionee nor any party to
which the Optionee's rights and privileges under the option may pass shall be,
or have any of the rights or privileges of, a shareholder of the Company with
respect to any of the shares of Common Stock issuable on the exercise of any
option granted under this Plan unless and until such option has been exercised
and the issuance (as evidenced by the appropriate entry on the books of the
Company or duly authorized transfer agent of the Company) of the stock
certificate evidencing such shares.

        14.3 Status as an Employee. Nothing in this Plan or any option granted
pursuant to this Plan shall confer on any Optionee any right to continue in the
employ of the Company, or to interfere in any way with the right of the Company
to terminate his or her employment or other relationship with the Company at any
time.

        14.4 Reservation of Shares. The Company, during the term of this Plan,
at all times will reserve and keep available such number of shares of Common
Stock as shall be sufficient to satisfy the requirements of this Plan.

15. Effectiveness of This Plan. This Plan shall become effective on the date on
which it is adopted by the Board of Directors of the Company (the "Effective
Date"). No option granted under this Plan to any officer or director of the
Company shall become exercisable until the Plan is approved by the shareholders,
and any option granted before such approval shall be conditioned on and is
subject to such approval.

               Adopted by the Board of Directors on __________________________
1999 and approved by the shareholders on ______________________________ , 2000.

                           UPGRADE INTERNATIONAL CORP.
                                     AMENDED
                    1999 COMBINED INCENTIVE AND NONQUALIFIED
                                STOCK OPTION PLAN

        THIS AGREEMENT is adopted by the Board of Directors of Upgrade
International Corp. and is effective as of the ___ day of ____________________,
1999.

        SECTION 1. Purpose. The purpose of the Plan is to enable Upgrade
International Corp. (the "Company") to attract and retain the services of people
with training, experience and ability and to provide additional incentive to
such persons by granting them an opportunity to participate in the ownership of
the Company.

        SECTION 2. Stock Subject to Plan. The stock subject to this Plan shall
be the Company's common stock, par value $0.001 per share (the "Common Stock"),
presently authorized but unissued or now held or subsequently acquired by the
Company as treasury shares. Subject to adjustment as provided in Section 10, the
aggregate amount of Common Stock reserved for issuance or delivery upon exercise
of all options granted under this Plan shall not exceed 1,550,000 shares of
Common Stock, as constituted on the date of adoption of this Plan by the Board
of Directors. If any option granted under this Plan shall expire or terminate
for any reason without having been exercised in full, the unpurchased shares
subject thereto shall thereupon again be available for purposes of this Plan.

        SECTION 3. Administration. The Plan shall be administered by the Board
of Directors of the Company, in accordance with the following terms and
conditions:

           3.1 General Authority. Subject to the express provisions of the Plan,
the Board of Directors shall have the authority, in its discretion, to determine
all matters relating to options to be granted under the Plan, including the
selection of individuals to be granted options, the number of shares to be
subject to each option, the exercise price, the term, whether such options shall
be immediately exercisable or shall become exercisable in increments over time,
and all other terms and conditions thereof. Grants under this Plan to persons
eligible need not be identical in any respect, even when made simultaneously.
The Board of Directors may from time to time adopt rules and regulations
relating to the administration of the Plan. The interpretation and construction
by the Board of Directors of any terms or provisions of this Plan or any option
issued hereunder, or of any rule or regulation promulgated in connection
herewith, shall be conclusive and binding on all interested parties. The Board
of Directors in its sole discretion, may grant incentive stock options
("Incentive Stock Options") as such term is defined in Section 422 of the U.S.
Internal Revenue Code of 1986, as amended, (the "Code") or nonqualified stock
options ("Nonqualified Stock Options") or both. A Nonqualified Stock Option is a
stock option that is not an Incentive Stock Option. The type of option granted,
whether an Incentive Stock option or a Nonqualified Stock Option shall be
clearly identified by the Board of Directors when granted. At no time shall the
Board grant an Incentive Stock Option and a Nonqualified Stock Option together,
or grant either an Incentive Stock Option or a Nonqualified Stock Option when
the exercise of one such option affects the right to exercise the other. The
term option when used in this Plan shall refer to Incentive Stock Options and
Nonqualified Stock Options, collectively.

           3.2 Directors. A member of the Board of Directors may be eligible to
participate in or receive or hold options under this Plan; provided, however,
that no

<PAGE>   2

member of the Board of Directors shall vote with respect to the granting of an
option hereunder to himself or herself, as the case may be.

           3.3 Delegation to a Committee. Notwithstanding the foregoing, the
Board of Directors, if it so determines, may delegate to a committee of the
Board of Directors any or all authority for the administration of the Plan, and
thereafter references to the Board of Directors in this Plan shall be deemed to
be references to the committee to the extent provided in the resolution
establishing the committee. Once appointed, any such committee shall continue to
serve until otherwise directed by the Board of Directors. From time to time the
Board of Directors may increase the size of the committee and appoint additional
members thereof, remove members (with or without cause), appoint substitutions
therefor, and fill vacancies however caused. Each member of the committee shall
be an individual qualifying as an "outside director," as such term is used in
Section 162(m) of the Code, and "non-employee director," as such term is used in
Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended
(the "1934 Act"). At least annually, such committee shall present a written
report to the Board of Directors indicating the persons to whom options have
been granted hereunder since the date of the last report, and in each case the
date or dates of options granted, the number of shares as to which options were
granted, and the exercise price per share. At all times the Board of Directors
shall have the power to remove all members of the committee and thereafter to
administer the Plan directly.

           3.4 Persons Subject to Section 16(b). Notwithstanding anything in the
Plan to the contrary, the Board of Directors, in its absolute discretion, may
bifurcate the Plan so as to restrict, limit or condition the use of any
provision of the Plan to participants who are officers and directors subject to
Section 16(b) of the 1934 Act without so restricting, limiting or conditioning
the Plan with respect to other participants

           3.5 Replacement of Options. The Board of Directors, in its absolute
discretion, may grant options subject to the condition that options previously
granted at a higher or lower exercise price under the Plan be canceled or
exchanged in connection with such grant. The number of shares covered by the new
options, the exercise price, the term and the other terms and conditions of the
new option, shall be determined in accordance with the Plan and may be different
from the provisions of the canceled or exchanged options. Alternatively, the
Board of Directors may, with the agreement of the Optionee, amend previously
granted options to establish the exercise price at the then current fair market
value of the Company's Common Stock, maintaining existing vesting and expiration
dates.

           3.6 Loans to Optionees. The Board of Directors, in its absolute
discretion, may provide that the Company loan to Optionees sufficient funds to
exercise any option granted under the Plan and/or to pay withholding tax due
upon exercise of such option. The Board of Directors shall have the authority to
make such determinations at the time of grant or exercise and shall establish
repayment terms thereof, including installments, maturity and interest rate.

        SECTION 4. Eligibility. Options may be granted only to persons who, at
the time the option is granted, are employees, directors, consultants or
independent contractors of or to the Company or any of its present or future
parent or subsidiary corporations (hereafter a "Parent" or "Subsidiary") or to
any other person providing good and valuable consideration to the Company is
received as may be determined by the Board of Directors. Any individual to whom
an option is granted under this Plan may be referred to hereinafter as
"Optionee". Any Optionee may receive one or more grants of options as the Board
of Directors as shall from time to time determine, and such

                                       2
<PAGE>   3

determinations may be different as to different Optionees and may vary as to
different grants. Optionees who are not employees are eligible to receive only
Nonqualified Stock Options.

        SECTION 5. Terms and Conditions of Options. Options granted under this
Plan shall be evidenced by written agreements which shall contain such terms,
conditions, limitations and restrictions as the Board of Directors shall deem
advisable and which are not inconsistent with this Plan. Each option granted
hereunder shall clearly indicate whether it is an Incentive Stock Option or a
Nonqualified Stock Option. Notwithstanding the foregoing, all such options shall
include or incorporate by reference the following terms and conditions:

           5.1 Number of Shares. The maximum number of shares that may be
purchased pursuant to the exercise of each option and the price per share at
which such option is exercisable (the "exercise price") shall be as established
by the Board of Directors, provided that the exercise price of Incentive Stock
Options shall not be less than the fair market value per share of the Common
Stock at the time the option is granted, as determined in good faith by the
Board of Directors. The exercise price of Nonqualified Stock Options may be
greater or less than the fair market value per share of the Common Stock at the
time the option is granted.

           5.2 Duration of Options. Subject to the restrictions contained in
Section 9, the term of each option shall be established by the Board of
Directors and, if not so established, shall be ten years from the date it is
granted; in no event, however, shall the term of an Incentive Stock Option
exceed ten years.

           5.3 Exercisability. Each option shall prescribe the installments, if
any, in which an option granted under the Plan shall become exercisable. The
Board of Directors, in its absolute discretion, may waive or accelerate any
installment requirement contained in outstanding options. In no case may an
option be exercised as to less than 100 shares at any one time (or the remaining
shares covered by the option if less than 100). Only whole shares shall be
issued upon the exercise of an option.

           5.4 Incentive Stock Option. Any option which is issued as an
Incentive Stock Option under this Plan shall, notwithstanding any other
provisions of this Plan or any option terms to the contrary, contain all of the
terms, conditions, restrictions, rights and limitations required to be contained
in an Incentive Stock Option, and any provision to the contrary shall be
disregarded.

        SECTION 6. Nontransferability of Options. Options granted under this
Plan and the rights and privileges conferred hereby may not be transferred,
assigned, pledged or hypothecated in any manner (whether by operation of law or
otherwise) other than by will or the applicable laws of descent and
distribution, and shall not be subject to execution, attachment or similar
process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise
dispose of any option under this Plan or any right or privilege conferred
hereby, contrary to the provisions hereof, or upon the sale or levy or any
attachment or similar process, such option thereupon shall terminate and become
null and void. During an Optionee's lifetime, any options granted under this
Plan are personal to him or her and are exercisable solely by such Optionee.

        SECTION 7. Certain Limitations Regarding Incentive Stock Options. The
grant of Incentive Stock Options shall be subject to the following special
limitations:

                                       3
<PAGE>   4

           7.1 Limitation on Amount of Grants. In any calendar year, only
options up to a maximum aggregate of ten percent (10%) of the number of shares
specified in Section 2 of this Plan shall be granted to any one person. In
addition, in no event shall any Optionee be granted Incentive Stock Options that
in the aggregate (together with all other Incentive Stock Options granted by the
Company or any Parents or Subsidiaries) entitle the Optionee to purchase, in any
calendar year during which such options first become exercisable, stock of the
Company, any Parent or any Subsidiary having a fair market value (determined as
of the time such options are granted) in excess of $100,000 plus the amount of
any unused limit carry-over permitted under the applicable provisions of the
Code. No limitation shall apply to Nonqualified Stock options.

           7.2 Grants to 10% Shareholders. Incentive Stock options may be
granted a person owning more than 10% of the total combined voting power of all
classes of stock of the Company and any Parent or Subsidiary only if (i) the
exercise price is at least 110% of the fair market value of the stock at the
time of grant, and (ii) the option is not exercisable after the expiration of
five years from the date of grant.

        SECTION 8. Exercise of Options. Options shall be exercised in accordance
with the following terms and conditions:

           8.1 Procedure. Options shall be exercised by delivery to the Company
of written notice of the number of shares with which the option is exercised.

           8.2 Payment. Payment of the option price shall be made in full within
5 business days of the notice of exercise of the option and shall be in cash or
bank-certified or cashier's checks, or personal check if permitted by the Board
of Directors. To the extent permitted by applicable laws and regulations
(including, but not limited to, federal tax and securities laws and
regulations), an option may be exercised by delivery of shares of Common Stock
of the Company held by the Optionee having a fair market value equal to the
exercise price, such fair market value to be determined in good faith by the
Board of Directors. Such payment in stock may occur in the context of a single
exercise of an option, sometimes referred to as a "cashless" exercise, or
successive and simultaneous exercises, sometimes referred to as "pyramiding",
which provides that, rather than physically exchanging certificates for a series
of exercises, bookkeeping entries will be made pursuant to which the Optionee is
permitted to retain his existing stock certificate and a new stock certificate
is issued for the net shares.

        If the Company's Common Stock is registered under the 1934 Act, and if
permitted by the Board of Directors, and to the extent permitted by applicable
laws and regulations, (including, but not limited to, federal tax and securities
laws and regulations) an option also may be exercised by delivery of a properly
executed exercise notice together with irrevocable instructions to a broker to
promptly deliver to the Company the amount of sale or loan proceeds to pay the
exercise price.

        8.3 Federal Withholding Tax Requirements. Upon exercise of an option,
the Optionee shall, upon notification of the amount due and prior to or
concurrently with the delivery of the certificates representing the shares, pay
to the Company amounts necessary to satisfy applicable federal, state and local
withholding tax requirements or shall otherwise make arrangements satisfactory
to the Company for such requirements. Such arrangements may include payment of
the appropriate withholding tax in shares of stock of the Company having a fair
market value equal to such withholding tax, either through delivery of shares
held by the Optionee or by reduction in the number of shares to be delivered to
the optionee upon exercise of such option.

        SECTION 9. Termination of Employment, Disability and Death.

           9.1 General. If the employment of an Optionee by the Company, a
Parent or a Subsidiary shall terminate by retirement or for any reason other
than death, disability or cause as hereinafter provided, an option held by the
Optionee may be exercised by the Optionee at any time prior to the expiration of
three months after the date of such termination of employment (unless by its
terms the option sooner terminates or expires), but only if, and to the extent,
the Optionee was entitled to exercise the option at the date of such
termination. Such three-month period shall be extended to one year after the
date of such termination in the event the Optionee dies during such three-month
period.

           9.2 Disability. If the employment of an Optionee by the Company, a
Parent or a Subsidiary is terminated because of the Optionee's disability (as
herein defined), an option held by the Optionee may be exercised by the Optionee
at any time prior to the expiration of one year after the date of such
termination of employment (unless by its terms the option sooner terminates or
expires), but only if, and to the extent, the Optionee was entitled to exercise
the option at the date of such termination. For purposes of this section, an
Optionee will be considered to be disabled if the Optionee is unable to engage
in any substantial gainful activity by reason of any medically determinable
mental or physical impairment which can be expected to result in death or which
has lasted or can be expected to last a continuous period of not less than 12
months.

           9.3 Death. In the event of the death of an Optionee while in the
employ of the Company, a Parent or a Subsidiary, an option held by the Optionee
shall be exercisable on or prior to the expiration of one year after the date of
such death (unless by its terms the option sooner terminates and expires), but
only if, and to the extent, the Optionee was entitled to exercise the option at
date of death and only by the Optionee's personal representative if the option
is then subject to administration as part of the Optionee's estate, or by the
person or persons to whom such Optionee's rights under the option shall have
passed by the Optionee's will or by applicable laws of descent and distribution.

           9.4 Termination for Cause. If an Optionee's employment with the
Company, a Parent or a Subsidiary is terminated for cause, any option granted
hereunder shall automatically terminate as of the first advice or discussion of
termination and such Optionee shall thereupon have no right to purchase any
shares pursuant to such option. "Termination for Cause" shall include but not be
limited to dismissal for dishonesty, conviction or confession of a crime
punishable by law (except minor violations), intoxication while at work, fraud,
misconduct or disclosure of confidential information.

           9.5 Waiver or Extension of Time Periods. The Board of Directors shall
have the authority, prior to or within the times specified in this Section 9 for
the exercise of any such option, to extend such time period or waive in its
entirety any such time period to the extent that such time period expires prior
to the expiration of the term of such option. In addition, the Board of
Directors may grant, pursuant to a specific resolution adopted at the time of
grant, modify or eliminate the time periods specified in this Section 9.
However, no Incentive Stock Option may be exercised after the expiration of ten
(10) years from the date such option is granted. If an Optionee holding an
Incentive Stock Option exercises such option, by permission, after the
expiration of the time period specified in this Section 9, the option will no
longer be treated as an Incentive

                                       5
<PAGE>   6

Stock Option under the Code and shall automatically be converted into a
Nonqualified Stock Option.

           9.6 Termination of Options. To the extent that the option of any
deceased Optionee or of any Optionee whose employment is terminated shall not
have been exercised within the limited periods prescribed in this Section 9, all
further rights to purchase shares pursuant to such option shall cease and
terminate at the expiration of such period. No Incentive Stock Option may be
exercised after the expiration of ten (10) years from the date such option is
granted, notwithstanding any provision to the contrary.

           9.7 Non-Employee Optionees. Options granted to Optionees who are not
employees of the Company, a Parent or a Subsidiary at the time of grant shall
not be subject to the provisions of this Section 9, except as specifically
provided in the option.

        SECTION 10. Option Adjustments.

           10.1 Adjustments Upon Changes in Capitalization. The aggregate number
and class of shares on which options may be granted under this Plan, the number
and class of shares covered by each outstanding option and the exercise price
per share thereof (but not the total price), and all such options, shall each be
proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock of the Company resulting from a split-up or consolidation
of shares or any like capital adjustment, or the payment of any stock dividend,
or any other increase or decrease in the number of shares of Common Stock of the
Company without the receipt of consideration by the Company.

           10.2 Effect of Certain Transactions. Except as provided in subsection
10.3, upon a merger, consolidation, acquisition of property or stock,
separation, reorganization or liquidation of the Company, as a result of which
the shareholders of the Company receive cash, stock or other property in
exchange for their shares of Common Stock, any option granted hereunder shall
terminate, provided, however, that the Optionee shall have the right for twenty
(20) days prior to any such merger, consolidation, acquisition of property or
stock, separation, reorganization or liquidation to exercise his or her option
in whole or in part whether or not the vesting requirements set forth in the
option agreement have been satisfied.

           10.3 Conversion of Options on Stock for Stock Exchange. If the
shareholders of the Company receive capital stock of another corporation
("Exchange Stock") in exchange for their shares of Common Stock in any
transaction involving a merger, consolidation, acquisition of property or stock,
separation or reorganization, all options granted hereunder shall terminate in
accordance with the provision of subsection 10.2 unless the Board of Directors
and the corporation issuing the Exchange Stock, in their sole and arbitrary
discretion and subject to any required action by the shareholders of the Company
and such corporation, agree that all such options granted hereunder are
converted into options to purchase shares of Exchange Stock. The amount and
price of the such options shall be determined by adjusting the amount and price
of the options granted hereunder in the same proportion as used for determining
the number of shares of Exchange Stock the holders of the Common Stock receive
in such merger, consolidation, acquisition of property or stock, separation or
reorganization. The vesting schedule set forth in the option agreement shall
continue to apply to the options granted for the Exchange Stock. In the case of
Incentive Stock Options, the provisions of this paragraph 10.3 shall be subject
to, and all related action shall satisfy, the requirements of Section 424(a) of
the Code.

                                       6
<PAGE>   7

           10.4 Fractional Shares. In the event of any adjustment in the number
of shares covered by any option, any fractional shares resulting from such
adjustment shall be disregarded and each such option shall cover only the number
of full shares resulting from such adjustment.

           10.5 Determination of Board of Directors to be Final. All such
adjustments pursuant to this Section 10, shall be made by the Board of
Directors, and its determination as to what adjustments shall be made, and the
extent thereof, shall be final, binding and conclusive.

        SECTION 11. Securities Regulations.

           11.1 Compliance. Shares shall not be issued with respect to an option
granted under this Plan unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, any applicable state
securities laws, the Securities Act of 1933, as amended, the 1934 Act, the rules
and regulations promulgated thereunder, and the requirements of any stock
exchange upon which the shares may then be listed, and shall further be subject
to the approval of counsel for the Company with respect to such compliance.
Inability of the Company to obtain, after reasonable efforts, from any
regulatory body having jurisdiction, the authority, deemed by the Company's
counsel to be necessary, for the lawful issuance and sale of shares upon
exercise of any option granted hereunder, shall relieve the Company of any
liability in respect of the nonissuance or sale of such shares as to which such
authority shall not have been obtained.

           11.2 Representations by Optionee. As a condition to the exercise of
an option, the Company may require the optionee to represent and warrant at the
time of any such exercise that the shares are being purchased only for
investment and without any present intention to sell or distribute such shares,
if, in the opinion of counsel for the Company, such representation is required
by any relevant provision of the laws referred to in Section 11.1. At the option
of the Company, a stop transfer order against any shares of stock so issued may
be placed on the official stock books and records of the Company, and a legend
indicating that the stock may not be pledged, sold or otherwise transferred
unless an opinion of counsel is provided (concurred in by counsel for the
Company) stating that such transfer is not in violation of any applicable law or
regulation, may be stamped on the stock certificate in order to assure exemption
from registration. The Board of Directors may also require such other action or
agreement by Optionees as may from time to time be necessary to comply with
federal and state securities laws. The Company shall not be obligated to
register options granted hereunder or the stock that may be purchased upon
exercise of such options.

        SECTION 12. Employment or Other Rights. Nothing in this Plan or any
option or right granted pursuant hereto shall confer upon any Optionee any right
to be continued in the employment of the Company, a Parent or Subsidiary or to
remain a director, officer or consultant, or to interfere in any way with the
right of the Company, a Parent or Subsidiary, in its sole discretion, to
terminate such Optionee's employment or other relationship at any time or to
remove the Optionee as a director or officer at any time.

        SECTION 13. Amendment and Termination.

           13.1 Action by Shareholders. The Plan may be terminated, modified or
amended by the shareholders of the Company.

                                       7
<PAGE>   8

           13.2 Action by Board of Directors. The Board of Directors may also
terminate the Plan, or modify or amend the Plan in such respects as it shall
deem advisable in order to conform to any changes in law or regulation
applicable thereto, or in other respects; provided, however, that the Board of
Directors may not, without further approval by the shareholders of the Company:

               (i) Increase the number of shares in the aggregate which may be
sold pursuant to options granted under the Plan;

               (ii) Increase the period during which options may be granted or
exercised; or

               (iii) Change the terms of the Plan in such manner as causes the
Plan to lose its qualification as an incentive stock option plan under Section
422 of the Code.

No termination, modification or amendment of the Plan may, without the consent
of each optionee to whom an option shall theretofore have been granted
hereunder, adversely affect the rights of such Optionee under such option.

        13.3 Automatic Termination. Unless the Plan shall theretofore have been
terminated as herein provided, this Plan shall terminate ten (10) years from the
earlier of: (i) the date on which the Plan is adopted; or (ii) the date on which
this Plan is approved by the shareholders of the Company. No option may be
granted after any such termination of this Plan. The termination, modification
or amendment of this Plan shall not, without the consent of an Optionee, alter
or impair any rights or obligations under any option theretofore granted under
this Plan to any such Optionee..

        SECTION 14. Effective Date of the Plan. This Plan shall become effective
on the date of its adoption by the Board of Directors of the Company and options
may be granted immediately thereafter, but no option may be exercised under the
Plan unless and until the Plan shall have been approved by the Company's
shareholders within 12 months after the date of adoption of the Plan by the
Board of Directors. If such approval is not obtained within such period, the
Plan and any options granted hereunder shall be null and void.

Adopted by the Board of Directors as of the ___ day of ___________________,
1999.
