TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED PURSUANT TO AN EFFECTIVE

                             MEDIQUIK SERVICES, INC.
                                WARRANT AGREEMENT

Pursuant to Section 1.5(b) of that certain Stock Purchase Agreement (the "Stock
Purchase Agreement") dated as of June 30, 2000, by and between MediQuik
Services, Inc. ("MediQuik") and MiraQuest Ventures, LLC ("MiraQuest"), MediQuik
hereby grants to MiraQuest a warrant to purchase 650,000 shares of Common Stock
of MediQuik (the "Shares"), at the Exercise Price subject to the terms and
conditions set forth below (the "Warrant").

      1. Defined Terms. Unless otherwise defined herein, the capitalized terms
used shall have the meaning ascribed to them in Exhibit A hereto.

      2. Vesting and Exercise; Expiration of Rights. The Warrant shall vest and
be exercisable on the first business day following the Closing Date. To the
extent not exercised, the Warrant shall expire and the warrants shall be
forfeited on the tenth anniversary of the Closing Date, without requirement of
further notice. No vesting requirements other than those listed in this Section
2 shall be applicable to the Warrant.

      3. Exercise Price. The Exercise Price for each of the Shares shall be
$0.60.

      4. Method of Exercise. The Warrant, to the extent exercisable, may be
exercised, in whole or in part, by providing written notice to the Company,
which notice shall designate the number of Shares to be purchased and shall be
accompanied by the full Exercise Price in readily available funds (cashier's
check or wire transfer) for the Shares.

      Alternatively, the Warrant, to the extent exercisable, may be exercised,
in whole or in part, by providing written notice to the Company that exercise
shall be made in the form of a Net Issuance ("Net Issuance Election"). For this
purpose, the term "Net Issuance" shall mean the number of Shares determined by
dividing:

      a.    The product of the number of Shares with respect to which the
            Warrant is exercised, multiplied by the excess of the Fair Market
            Value of a Share on the Exercise Date over the Exercise Price of a
            Warrant;

      by:
<PAGE>

      b.    The fair market value of a Share on the Exercise Date.

For purposes of this Section 4, the "Fair Market Value" of a Share as of a
particular date shall be determined as follows: (i) if traded on a securities
exchange or through the Nasdaq National Market, the value shall be deemed to be
the average of the closing prices of the securities on such exchange over the
thirty (30) day period ending three (3) days prior to the Net Issuance
Election; (ii) if traded over-the-counter (OTCBB or pink sheets), the value
shall be deemed to be the average of the closing bid or sale prices (whichever
is applicable) over the thirty (30) day period ending three (3) days prior to
the Net Issuance Election; and (iii) if there is no active public market, the
value shall be the fair market value thereof, as determined in good faith by the
Board of Directors of MediQuik.

      5. Delivery of Securities. Delivery of certificates representing the
Shares shall be made by MediQuik promptly after receipt of notice of exercise of
the Warrant and payment in full for the affected shares. Such shares shall bear
a legend in substantially the form attached hereto as Exhibit B. In connection
with the issuance and delivery of the Shares hereunder, MiraQuest agrees to
deliver to MediQuik such additional documents as MediQuik may reasonably require
to ensure compliance with applicable Federal and State Securities laws.

      6. Status of Warrant and Common Stock. Neither the Warrant granted herein
nor the Shares issuable upon exercise of the Warrant have been registered under
the Act or under any applicable state securities law or regulation. The Warrant
and the Shares issuable upon exercise of the Warrant are restricted securities
within the meaning of Rule 144 promulgated under the Act and resales thereof are
subject to the limitations imposed under such rule.

      7. Rights as Shareholder. Prior to the issuance of Shares upon the
exercise of the Warrant, MiraQuest shall have no rights as a shareholder or
right to dividends or dividend equivalents, each with respect to the shares
subject to the Warrant.

      8. Reservation of Shares. MediQuik shall, during the term of the Warrant,
reserve for issuance and delivery upon exercise of the Warrant the number of
shares equal to the shares. Such shares may be authorized but unissued shares,
treasury shares, or shares acquired on the open market or by private purchase.
When issued hereunder upon the exercise of the Warrant, all such shares shall be
duly authorized, validly issued, fully paid and nonassessable and free of all
preemptive rights.

      9. Adjustment of Exercise Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the Exercise
Price shall be subject to adjustment from time to time as follows:

            (a) Subdivisions. Combinations and Other Issuances. If MediQuik
            shall at any time prior to the expiration of this Warrant subdivide
            its Common Stock, by split-up or otherwise, or issue additional
            shares of its Common Stock as a dividend with respect to any shares
            of its Common Stock, the number of Shares issuable on the exercise
            of this Warrant shall forthwith be proportionately increased in the
            case of a subdivision or stock dividend, or proportionately
            decreased in the case of a combination. Appropriate adjustments
            shall also be

                                        2
<PAGE>

            made to the Exercise Price, but the aggregate Exercise Price payable
            for the total number of Shares purchasable under this Warrant (as
            adjusted) shall remain the same. Any adjustment under this Section
            9(a) shall become effective at the close of business on the date
            the subdivision or combination becomes effective, or as of the
            record date of such dividend, or in the event that no record date is
            fixed, upon the making of such dividend.

            (b) Reclassification. Reorganization and Consolidation. In case of
            any reclassification, capital reorganization, or change in the
            Common Stock of MediQuik (other than as a result of a subdivision,
            combination, or stock dividend provided for in Section 9(a) above),
            then, as a condition of such reclassification, reorganization, or
            change, lawful provision shall be made, and duly executed documents
            evidencing the same from MediQuik or its successor shall be
            delivered to the Holder, so that the Holder shall have the right at
            any time prior to the expiration of this Warrant to purchase, at a
            total price equal to that payable upon the exercise of this Warrant,
            the kind and amount of shares of stock and other securities and
            property receivable in connection with such reclassification,
            reorganization, or change by a holder of the same number of shares
            of Common Stock as were purchasable by the Holder immediately prior
            to such reclassification, reorganization, or change. In any such
            case appropriate provisions shall be made with respect to the rights
            and interest of the Holder so that the provisions hereof shall
            thereafter be applicable with respect to any shares of stock or
            other securities and property deliverable upon exercise hereof, and
            appropriate adjustments shall be made to the Exercise Price payable
            hereunder, provided the aggregate Exercise Price shall remain the
            same.

            (c) Adjustment for Capital Reorganization. Merger or Consolidation.
            In case of any capital reorganization of the capital stock of
            MediQuik (other than a combination, reclassification, exchange or
            subdivision of shares otherwise provided for herein), or any merger
            or consolidation of MediQuik with or into another corporation
            whether or not MediQuik is the surviving corporation, or the sale of
            all or substantially all of the assets of MediQuik, then, and in
            each such case, as a part of such reorganization, merger,
            consolidation, sale or transfer, lawful provision shall be made so
            that the Holder of this Warrant shall thereafter be entitled to
            receive upon exercise of this Warrant, during the period specified
            herein and upon payment of the Exercise Price then in effect, the
            number of shares of stock or other securities or property of the
            successor corporation resulting from such reorganization, merger,
            consolidation, sale or transfer that the Holder would have been
            entitled to if this Warrant had been exercised immediately before
            such reorganization, merger, consolidation, sale or transfer, all
            subject to further adjustment as provided in this Section 9. The
            foregoing provisions of this Section 9(c) shall similarly apply to
            successive reorganizations, consolidations, mergers, sales and
            transfers and to the stock or securities of any other corporation
            that are at the time receivable upon the exercise of this Warrant.
            If the per share consideration payable to the Holder hereof for
            shares in connection with any such transaction is in a form other
            than cash or marketable securities, then the value of such
            consideration shall be determined in good faith

                                        3
<PAGE>

            by MediQuik's Board of Directors. In all events, appropriate
            adjustment (as determined in good faith by MediQuik's Board of
            Directors) shall be made in the application of the provisions of
            this Warrant with respect to the rights and interests of the Holder
            after the transaction, to the end that the provisions of this
            Warrant shall be applicable after that event to the greatest extent
            possible.

            (d) Notice of Adjustment. When any adjustment is required to be made
            in the number or kind of shares purchasable upon exercise of the
            Warrant, or in the Exercise Price, MediQuik shall promptly notify
            the holder of such event and (i) of the number of shares of Common
            Stock or other securities or property thereafter purchasable upon
            exercise of this Warrant and (ii) the Exercise Price after such
            adjustment.

      10. No Assignment. No portion of the Warrant shall be subject in any
manner to sale, transfer, pledge, assignment or other encumbrance or
disposition, whether by operation of law or otherwise and whether voluntarily or
involuntarily, except by will or the laws of descent and distribution and as
specifically permitted under Paragraph 11 (collectively, a "Transfer"). In the
event of a Transfer other than permitted hereunder, the transferred portion of
the Warrant shall be canceled and forfeited as of the date of such Transfer,
without requirement of further notice.

      11. Transfers. MiraQuest may transfer all or any portion of its rights to
receive the Shares under this Warrant to any of its executive officers, Board
members, subsidiaries, or related companies or executive officers thereof.
MiraQuest may make such a transfer by providing written notice to the Company,
which notice shall designate (a) the number of the Shares such transferee shall
have the right to exercise pursuant to the transfer and (b) the name, address,
and taxpayer identification number of the transferee. MediQuik shall then issue
a new Warrant or Warrants to the person or persons entitled thereto in
substantially the same form as this Warrant, provided that no transferee shall
have the right to further transfer or subdivide such warrant.

      12. Amendment; Termination. The terms and conditions set forth herein may
be amended or this agreement may be terminated by the written consent of the
parties hereto.

                       2000 NONQUALIFIED STOCK OPTION PLAN

1. Establishment, Purpose and Types of Options

      Nastech Pharmaceutical Company Inc. hereby establishes the Nastech
Pharmaceutical Company Inc. 2000 Nonqualified Stock Option Plan (the "Plan").
The purpose of the Plan is to promote the long-term growth and profitability of
Nastech Pharmaceutical Company Inc (the "Corporation") by (i) providing
employees, officers and directors with incentives to improve stockholder value
and to contribute to the growth and financial success of the Corporation, and
(ii) enabling the Corporation to attract and retain as employees, officers and
directors the best available persons.

      The Plan shall be administered as a "broadly based" plan, as such term is
defined and interpreted by the National Association of Securities Dealers, Inc.
("NASD") under NASD Rule 4310(c)(25)(G), under which more than 50 percent of the
Options will be granted to rank and file employees who are neither officers
(which includes any employees at the level of Vice President or above) or
directors of the Corporation. The Plan permits the granting of stock options
which are not qualified under Section 422 of the Internal Revenue Code of 1986,
as amended ("Options").

disposition of substantially all of the Corporation's assets or over 50% of its
Common Stock; or (ii) any merger, share exchange, consolidation or other
reorganization or business combination in which the Corporation is not the
surviving or continuing corporation, or in which the Corporation's stockholders
become entitled to receive cash, securities of the Corporation other than voting
common stock, or securities of another issuer.

      (c) "Code" shall mean the Internal Revenue Code of 1986, as amended, and
any regulations issued thereunder.

      (d) "Committee" shall mean the Board or committee of Board members
appointed pursuant to Section 3 of the Plan to administer the Plan.

      (e) "Common Stock" shall mean shares of the Corporation's common stock.

      (f) "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended.

      (g) "Fair Market Value" of a share of the Corporation's Common Stock for
any purpose on a particular date shall be determined as follows: (1) if there is
a public market for the Common Stock, the Fair Market Value per share shall be
the average of the bid and asked prices of the Common Stock for such day if the
Common Stock is then included for quotation on the Nasdaq Small-Cap Market or,
the Fair Market Value per share shall be the closing price of the Common Stock
for such day if the Common Stock is then included on the Nasdaq National Market
or listed on the New York, American or Pacific Stock Exchange, or (2) if there
is no public market for the Common Stock, the Fair Market Value of the Common
Stock shall be determined in good faith by the Board or Committee in such manner
as it may deem equitable for Plan purposes. The Board or the Committee may rely

for purposes of the calculation of the Fair Market Value per share as set forth
above.

designate at the time of taking such formal action.

within the meaning of the definition of "parent corporation" provided in Section
424(e) of the Code, or any successor thereto of similar import.

      (k) "Rule 16b-3" shall mean Rule 16b-3 as in effect under the Exchange Act
on the effective date of the Plan, or any successor provision prescribing
conditions necessary to exempt the issuance of securities under the Plan (and
further transactions in such securities) from Section 16(b) of the Exchange Act.

      (l) "Subsidiary" and "subsidiaries" shall mean only a corporation or
corporations, whether now or hereafter existing, within the meaning of the
definition of "subsidiary corporation" provided in Section 424(f) of the Code,
or any successor thereto of similar import.

3. Administration

      (a) Procedure. The Plan shall be administered by the Board. In the
alternative, the Board may appoint a Committee to administer the Plan consisting
solely of two (2) or more members of the Board who are "nonemployee directors"
within the meaning of Rule 16b-3 and "outside directors" within the meaning of
Code Section 162(m). Once appointed, the 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 thereof, remove members
(with or without cause) and appoint new members in substitution therefor, fill
vacancies, however caused, and remove all members of the Committee and,
thereafter, directly administer the Plan. In the event that the Board is the
administrator of the Plan in lieu of a Committee, the term "Committee" as used
herein shall be deemed to mean the Board.

            Members of the Board or Committee who are either eligible for
Options or have been granted Options may vote on any matters affecting the
administration of the Plan or the grant of Options pursuant to the Plan, except
that no such member shall act upon the granting of an Option to himself or
herself, but any such member may be counted in determining the existence of a
quorum at any meeting of the Board or the Committee during which action is taken
with respect to the granting of an Option to him or her.

            The Committee shall meet at such times and places and upon such
notice as it may determine. A majority of the Committee shall constitute a
quorum. Any acts by the Committee may be taken at any meeting at which a quorum
is present and shall be by majority vote of those members entitled to vote.
Additionally, any acts reduced to writing or approved in writing by all of the
members of the Committee shall be valid acts of the Committee.

      (b) Powers of the Committee. The Committee shall have all the powers
vested in it by the terms of the Plan, such powers to include authority, in its
sole and absolute discretion, to grant Options under the Plan, prescribe Grant
Agreements evidencing such Options and establish programs for granting Options.
The Committee shall have full power and authority to take all other actions
necessary to carry out the purpose and intent of the Plan, including, but not
limited to, the authority to:

            (i) determine the eligible persons to whom, and the time or times at
which Options shall be granted,

            (ii) determine the number of shares to be covered by or used for
reference purposes for each Option,

<PAGE>

            (iii) impose such terms, limitations, restrictions and conditions
upon any such Option as the Committee shall deem appropriate,

            (iv) modify, extend or renew outstanding Options, accept the
surrender of outstanding Options and substitute new Options, provided that no
such action shall be taken with respect to any outstanding Option which would
adversely affect the grantee without the grantee's consent, and

            (v) accelerate or otherwise change the time in which an Option may
be exercised or becomes payable and to waive or accelerate the lapse, in whole
or in part, of any restriction or condition with respect to such Option,
including, but not limited to, any restriction or condition with respect to the
vesting or exercisability of an Option following termination of any grantee's
employment.

The Committee shall have full power and authority to administer and interpret
the Plan and to adopt such rules, regulations, agreements, guidelines and
instruments for the administration of the Plan and for the conduct of its
business as the Committee deems necessary or advisable and to interpret the
same, all within the Committee's sole and absolute discretion.

      (d) Limited Liability. To the maximum extent permitted by law, no member
of the Board or Committee shall be liable for any action taken or decision made
in good faith relating to the Plan or any Option thereunder.

      (e) Indemnification. To the maximum extent permitted by law, the members
of the Board and Committee shall be indemnified by the Corporation in respect of
all their activities under the Plan.

      (f) Effect of Committee's Decision. All actions taken and decisions and
determinations made by the Committee on all matters relating to the Plan
pursuant to the powers vested in it hereunder shall be in the Committee's sole
and absolute discretion and shall be conclusive and binding on all parties
concerned, including the Corporation, its stockholders, any participants in the
Plan and any other employee of the Corporation, and their respective successors
in interest.

4. Shares Available for the Plan; Maximum Options

      Subject to adjustments as provided in Section 9 of the Plan, the shares of
stock that may be delivered or purchased under the Plan shall not exceed an
aggregate of 700,000 shares of Common Stock of the Corporation and the
Corporation shall reserve said number of shares of Common Stock for issuance
pursuant to the Plan. If any Option, or portion of an Option, under the Plan
expires or terminates unexercised, becomes unexercisable or is forfeited or
otherwise terminated, surrendered or canceled as to any shares, the shares
subject to such Option shall thereafter be available for further Options under
the Plan.

5. Participation

      Participation in the Plan shall be open to all employees, officers, and
directors of the Corporation, or of any Parent or Subsidiary of the Corporation,
as may be selected by the Committee from time to time. Options may be granted to
such eligible persons and for or with respect to such number of shares of Common
Stock as the Committee shall determine, subject to the limitations in Sections 1
and 4 of the Plan. A grant of an Option made in any one year to an eligible
person shall neither guarantee nor preclude a further grant of an Option to such
person in that year or subsequent years.

6. Stock Options

      Subject to the other applicable provisions of the Plan, the Committee may
from time to time grant to eligible participants nonqualified stock options,
which shall be subject to the following terms and conditions.

<PAGE>

      (a) Grant of Option. The grant of a stock option shall be evidenced by a
Grant Agreement, executed by the Corporation and the grantee, stating the number
of shares of Common Stock subject to the stock option evidenced thereby and the
terms and conditions of such stock option, in such form as the Committee may
from time to time determine.

      (b) Price. The price per share payable upon the exercise of each stock
option ("exercise price") shall be determined by the Committee, but in no event
shall be less than 100% of the Fair market value of the Common Stock on the
Grant Date.

      (c) Payment. Stock options may be exercised in whole or in part by payment
of the exercise price of the shares to be acquired in accordance with the
provisions of the Grant Agreement, and/or such rules and regulations as the
Committee may have prescribed, and/or such determinations, orders, or decisions
as the Committee may have made. Payment may be made in cash (or cash equivalents
acceptable to the Committee) or, if permitted by the Committee in its sole
discretion, in shares of Common Stock or a combination of cash and shares of
Common Stock, or by such other means as the Committee may prescribe. The Fair
Market Value of shares of Common Stock delivered on exercise of stock options
shall be determined as of the date of exercise. Shares of Common Stock delivered
in payment of the exercise price may be previously owned shares or, if approved
by the Committee, shares acquired upon exercise of the stock option. Any
fractional share will be paid in cash. The Corporation may make or guarantee
loans to grantees to assist grantees in exercising stock options and satisfying
any related withholding tax obligations.

      If the Common Stock is registered under Section 12(b) or 12(g) of the
Exchange Act, the Committee, subject to such limitations as it may determine,
may authorize payment of the exercise price, in whole or in part, by delivery of
a properly executed exercise notice, together with irrevocable instructions, to:
(i) a brokerage firm to deliver promptly to the Corporation the aggregate amount
of sale or loan proceeds to pay the exercise price and any withholding tax
obligations that may arise in connection with the exercise, and (ii) the
Corporation to deliver the certificates for such purchased shares directly to
such brokerage firm.

      (d) Terms of Options. The term during which each stock option may be
exercised shall be determined by the Committee; provided, however, that in no
event shall a stock option be exercisable more than ten years from the date it
is granted. Prior to the exercise of the stock option and delivery of the shares
certificates represented thereby, the grantee shall have none of the rights of a
stockholder with respect to any shares represented by an outstanding stock
option.

      (e) Other Terms and Conditions. Stock options may contain such other
provisions, not inconsistent with the provisions of the Plan, as the Committee
shall determine appropriate from time to time.

7. Withholding of Taxes

      The Corporation may require, as a condition to the exercise of an Option
granted under the Plan (hereinafter collectively referred to as a "taxable
event"), that the grantee pay to the Corporation, in cash or, if permitted by
the Committee in its sole discretion, in shares of Common Stock, including
shares acquired upon exercise of the Option, valued at Fair Market Value on the
date as of which the withholding tax liability is determined, any federal, state
or local taxes of any kind required by law to be withheld with respect to any
taxable event under the Plan. The Corporation, to the extent permitted or
required by law, shall have the right to deduct from any payment of any kind
(including salary or bonus) otherwise due to a grantee any federal, state or
local taxes of any kind required by law to be withheld with respect to any
taxable event under the Plan, or to retain or sell without notice a sufficient
number of the shares to be issued to such grantee to cover any such taxes.

8. Transferability

<PAGE>

      No Option granted under the Plan shall be transferable by a grantee other
than by will or the laws of descent and distribution. Unless otherwise
determined by the Committee in accord with the provisions of the immediately
preceding sentence, an Option may be exercised during the lifetime of the
grantee, only by the grantee or, during the period the grantee is under a legal
disability, by the grantee's guardian or legal representative.

9. Adjustments; Business Combinations

      In the event of a reclassification, recapitalization, stock split, stock
dividend, combination of shares, or other similar event, the maximum number and
kind of shares reserved for issuance or with respect to which Options may be
granted under the Plan as provided in Section 4 shall be adjusted to reflect
such event, and the Committee shall make such adjustments as it deems
appropriate and equitable in the number, kind and price of shares covered by
outstanding Options made under the Plan, and in any other matters which relate
to Options and which are affected by the changes in the Common Stock referred to
above.

      In the event of any proposed Change in Control, the Committee shall take
such action as it deems appropriate and equitable to effectuate the purposes of
this Plan and to protect the grantees of Options, which action may include, but
without limitation, any one or more of the following: (i) acceleration or change
of the exercise and/or expiration dates of any Option to require that exercise
be made, if at all, prior to the Change in Control; (ii) cancellation of any
Option upon payment to the holder in cash of the Fair Market Value of the Common
Stock subject to such Option as of the date of (and, to the extent applicable,
as established for purposes of) the Change in Control, less the aggregate
exercise price, if any, of the Option; and (iii) in any case where equity
securities of another entity are proposed to be delivered in exchange for or
with respect to Common Stock of the Corporation, arrangements to have such other
entity replace the Options granted hereunder with Options with respect to such
other securities, with appropriate adjustments in the number of shares subject
to, and the exercise prices under, the Option.

      In the event the Corporation dissolves and liquidates (other than pursuant
to a plan of merger or reorganization), then notwithstanding any restrictions on
exercise set forth in this Plan or any Grant Agreement, or other agreement
evidencing a stock option: (i) each grantee shall have the right to exercise his
stock option at any time up to ten (10) days prior to the effective date of such
liquidation and dissolution; and (ii) the Committee may make arrangements with
the grantees for the payment of appropriate consideration to them for the
cancellation and surrender of any stock option that is so canceled or
surrendered at any time up to ten (10) days prior to the effective date of such
liquidation and dissolution. The Committee may establish a different period (and
different conditions) for such exercise, delivery, cancellation, or surrender to
avoid subjecting the grantee to liability under Section 16(b) of the Exchange
Act. Any stock option not so exercised, canceled, or surrendered shall terminate
on the last day for exercise prior to such effective date.

      Except as herein expressly provided, issuance by the Corporation of shares
of stock of any class or securities convertible into shares of stock of any
class, for cash, property, labor or services, upon direct sale, upon the
exercise of rights or warranty to subscribe therefore, or upon conversion of
shares or obligations of the Corporation convertible into such shares or other
securities, and in any case whether or not for fair value, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number of
shares of Common Stock subject to Options theretofore granted or the purchase
price per share of Common Stock subject to Options.

10. Termination and Modification of the Plan

      The Board, without further approval of the stockholders, may modify or
terminate the Plan or any portion thereof at any time, except that no
modification shall become effective without prior approval of the stockholders
of the Corporation if stockholder approval is necessary to comply with any tax
or regulatory requirement or rule of any exchange or Nasdaq System upon which
the Common Stock is listed or quoted.

<PAGE>

      The Committee shall be authorized to make minor or administrative
modifications to the Plan as well as modifications to the Plan that may be
dictated by requirements of federal or state laws applicable to the Corporation
or that may be authorized or made desirable by such laws. The Committee may
amend or modify the grant of any outstanding Option in any manner to the extent
that the Committee would have had the authority to make such Option as so
modified or amended. No modification may be made that would materially adversely
affect any Option previously made under the Plan without the approval of the
grantee.

11. Non-Guarantee of Employment

      Nothing in the Plan or in any Grant Agreement thereunder shall confer any
right on an employee to continue in the employ of the Corporation or shall
interfere in any way with the right of the Corporation to terminate an employee
at any time.

12. Termination of Employment

      For purposes of maintaining a grantee's continuous status as an employee
and accrual of rights under any Option, transfer of an employee among the
Corporation and the Corporation's Parent or Subsidiaries shall not be considered
a termination of employment. Nor shall it be considered a termination of
employment for such purposes if an employee is placed on military or sick leave
or such other leave of absence which is considered as continuing intact the
employment relationship; in such a case, the employment relationship shall be
continued until the date when an employee's right to reemployment shall no
longer be guaranteed either by law or contract.

13. Written Agreement

      Each Grant Agreement entered into between the Corporation and a grantee
with respect to an Option granted under the Plan shall incorporate the terms of
this Plan and shall contain such provisions, consistent with the provisions of
the Plan, as may be established by the Committee.

14. Non-Uniform Determinations

      The Committee's determinations under the Plan (including, without
limitation, determinations of the persons to receive Options, the form, amount
and timing of such Options, the terms and provisions of such Options and the
agreements evidencing the same) need not be uniform and may be made by it
selectively among persons who receive, or are eligible to receive, Options under
the Plan, whether or not such persons are similarly situated.

15. Limitation on Benefits

      With respect to persons subject to Section 16 of the Exchange Act,
transactions under this Plan are intended to comply with all applicable
conditions of Rule 16b-3. To the extent any provision of the Plan or action by
the Committee fails to so comply, it shall be deemed null and void, to the
extent permitted by law and deemed advisable by the Committee.

16. Listing and Registration

      If the Corporation determines that the listing, registration or
qualification upon any securities exchange or upon any listing or quotation
system established by the National Association of Securities Dealers, Inc.
("Nasdaq System") or under any law, of shares subject to any Option is necessary
or desirable as a condition of, or in connection with, the granting of same or
the issue or purchase of shares thereunder, no such Option may be exercised in
whole or in part and no restrictions on such Option shall lapse, unless such
listing, registration or qualification is effected free of any conditions not
acceptable to the Corporation.

<PAGE>

17. Compliance with Securities Law

      Common Stock shall not be issued with respect to an Option granted under
the Plan unless the exercise of such Option and the issuance and delivery of
share certificates for such Common Stock pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any national securities exchange or Nasdaq
System upon which the Common Stock may then be listed or quoted, and shall be
further subject to the approval of counsel for the Corporation with respect to
such compliance to the extent such approval is sought by the Committee.

      Stock certificates evidencing unregistered shares acquired upon the
exercise of Options shall contain a restrictive securities legend substantially
as follows:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE OR
OTHER JURISDICTION. THE SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE IN THE
ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND APPLICABLE SECURITIES LAWS OF ANY STATE
OR OTHER JURISDICTION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT
SUCH REGISTRATION IS NOT REQUIRED."

18. No Restriction of Corporate Action

      Nothing contained in the Plan shall be construed to prevent the
Corporation or any Parent or Subsidiary from taking any corporate action which
is deemed by the Corporation or such Parent or Subsidiary to be appropriate or
in its best interest, whether or not such action would have an adverse effect on
the Plan or any Option issued under the Plan. No employee, beneficiary or other
person shall have any claim against the Corporation or any Parent or Subsidiary
as a result of such action.

19. No Trust or Fund Created

      Neither the Plan nor any Option shall create or be construed to create a
trust or separate fund of any kind or a fiduciary relationship between the
Corporation and a grantee or any other person. To the extent that any grantee or
other person acquires a right to receive stock or other consideration from the
Corporation pursuant to an Option, such right shall be no greater than the right
of any unsecured general creditor of the Corporation.

20. Governing Law

      The validity, construction and effect of the Plan, of Grant Agreements
entered into pursuant to the Plan, and of any rules, regulations, determinations
or decisions made by the Board or Committee relating to the Plan or such Grant
Agreements, and the rights of any and all persons having or claiming to have any
interest therein or thereunder, shall be determined exclusively in accordance
with applicable federal laws and the laws of the State of Delaware without
regard to its conflict of laws rules and principles.

21. Plan Subject to Articles and By-Laws

      This Plan is subject to the Certificate of Incorporation and By-Laws of
the Corporation, as they may be amended from time to time.

22. Effective Date; Termination Date

      The Plan is effective as of August 7, 2000, the date on which the Plan was
adopted by the Board. No Option shall be granted under the Plan after the close
of business on the day immediately preceding the tenth anniversary of the
effective date of the Plan. Subject to other applicable provisions of the Plan,
all

<PAGE>

Options made under the Plan prior to such termination of the Plan shall remain
in effect until such Options have been satisfied or terminated in accordance
with the Plan and the terms of such Options.
