                   any outstanding Award which would adversely affect the
                   grantee without the grantee's consent,

             (vi)  accelerate or otherwise change the time in which an Award 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

                                      -3-
<PAGE>

The Committee shall have full power and authority to administer and interpret

instruments for the administration of the Plan and for the conduct of its
business as the Committee deems necessary or advisable and to interpret 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 Award 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 Awards

    Subject to adjustments as provided in Section 12 of the Plan, the shares of
stock that may be delivered or purchased or used for reference purposes (with
respect to stock appreciation rights, phantom stock units or performance awards
payable in cash) with respect to Awards granted under the Plan, including with
respect to incentive stock options intended to qualify under Section 422 of the
Code, shall not exceed an aggregate of Three Million (3,000,000) shares of
Common Stock of the Corporation.  The Corporation shall reserve said number of
shares for Awards under the Plan, subject to adjustments as provided in Section
12 of the Plan.  If any Award, or portion of an Award, under the Plan expires or
terminates unexercised, becomes unexercisable or is forfeited or otherwise
terminated, surrendered or canceled as to any shares without the delivery of
shares of Common Stock or other consideration, the shares subject to such Award
shall thereafter be available for further Awards under the Plan.

                                      -4-
<PAGE>

    The maximum number of shares of Common Stock subject to Awards of any
combination that may be granted during any one calendar year to any one
individual shall be limited to One Million (1,000,000).  To the extent required
by Section 162(m) of the Code and so long as Section 162(m) of the Code is
applicable to persons eligible to participate in the Plan, shares of Common
Stock subject to the foregoing limit with respect to which the related Award is
terminated, surrendered or canceled shall not again be available for grant under
this limit.

5.  Participation

    Participation in the Plan shall be open to all employees, officers,
directors and consultants of the Corporation, or of any Parent or Subsidiary of
the Corporation, as may be selected by the Committee from time to time.
Notwithstanding the foregoing, participation in the Plan with respect to Awards
of incentive stock options shall be limited to employees of the Corporation or
of any Parent or Subsidiary of the Corporation.

    Awards 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 Section 4 of the Plan.  A grant of any type of Award made
in any one year to an eligible person shall neither guarantee nor preclude a
further grant of that or any other type of Award 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 Awards of nonqualified stock
options or incentive stock options as that term is defined in Section 422 of the
Code.  The stock option Awards granted shall be subject to the following terms
and conditions.

    (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.

    (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, unless otherwise determined by the
Committee, in shares of Common Stock or a combination of cash and shares of
Common Stock, or by such other means as the

                                      -5-
<PAGE>

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 designated by the Corporation 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) Restrictions on Incentive Stock Options.  Incentive stock option Awards
granted under the Plan shall comply in all respects with Code Section 422 and,
as such, shall meet the following additional requirements:

        (i)   Grant Date. An incentive stock option must be granted within 10
              years of the earlier of the Plan's adoption by the Board of
              Directors or approval by the Corporation's shareholders.

        (ii)  Exercise Price and Term. The exercise price of an incentive stock
              option shall not be less than 100% of the Fair Market Value of the
              shares on the date the stock option is granted and the term of the
              stock option shall not exceed ten years. Also, the exercise price
              of any incentive stock option granted to a grantee who owns
              (within the meaning of Section 422(b)(6) of the Code, after the
              application of the attribution rules in Section 424(d) of the
              Code) more than 10% of the total combined voting power of all
              classes of shares of the Corporation or its Parent or Subsidiary
              corporations (within the meaning of Sections 422 and 424 of the
              Code) shall be not less than 110% of the Fair Market Value of the
              Common Stock on the grant date and the term of such stock option
              shall not exceed five years.

                                      -6-
<PAGE>

        (iii) Maximum Grant. The aggregate Fair Market Value (determined as of
              the Grant Date) of shares of Common Stock with respect to which
              all incentive stock options first become exercisable by any
              grantee in any calendar year under this or any other plan of the
              Corporation and its Parent and Subsidiary corporations may not
              exceed $100,000 or such other amount as may be permitted from time
              to time under Section 422 of the Code. To the extent that such
              aggregate Fair Market Value shall exceed $100,000, or other
              applicable amount, such stock options shall be treated as
              nonqualified stock options. In such case, the Corporation may
              designate the shares of Common Stock that are to be treated as
              stock acquired pursuant to the exercise of an incentive stock
              option by issuing a separate certificate for such shares and
              identifying the certificate as incentive stock option shares in
              the stock transfer records of the Corporation.

        (iv)  Grantee. Incentive stock options shall only be issued to employees
              of the Corporation, or of a Parent or Subsidiary of the
              Corporation.

        (v)   Designation. No stock option shall be an incentive stock option
              unless so designated by the Committee at the time of grant or in
              the Grant Agreement evidencing such stock option.

        (vi)  Stockholder Approval. No stock option issued under the Plan shall
              be an incentive stock option unless the Plan is approved by the
              shareholders of the Corporation within 12 months of its adoption
              by the Board in accordance with the Bylaws and Articles of the
              Corporation and governing law relating to such matters.

    (f) 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.  Stock Appreciation Rights

    (a) Award of Stock Appreciation Rights.  Subject to the other applicable
provisions of the Plan, the Committee may at any time and from time to time
grant stock appreciation rights ("SARs") to eligible participants, either on a
free-standing basis (without regard to or in addition to the grant of a stock
option) or on a tandem basis (related to the grant of an underlying stock
option), as it determines.  SARs granted in tandem with or in addition to a
stock option may be granted either at the same time as the stock option or at a
later time; provided, however, that a tandem SAR shall not be granted with
respect to any outstanding incentive stock option Award without the consent of
the grantee.  SARs shall be evidenced by Grant Agreements, executed by the
Corporation and the grantee, stating the number of shares of Common Stock
subject to the SAR evidenced thereby and the terms and conditions of such SAR,
in such form as the Committee may from time to time determine.  The term during
which each SAR may be exercised shall be determined by the Committee.  In no
event shall a SAR be exercisable more than ten years from the date it is
granted.  The grantee shall have none of the rights

                                      -7-
<PAGE>

of a stockholder with respect to any shares of Common Stock represented by a
SAR.

    (b) Restrictions of Tandem SARs.  No incentive stock option may be
surrendered in connection with the exercise of a tandem SAR unless the Fair
Market Value of the Common Stock subject to the incentive stock option is
greater than the exercise price for such incentive stock option.  SARs granted
in tandem with stock options shall be exercisable only to the same extent and
subject to the same conditions as the stock options related thereto are
exercisable.  The Committee may, in its discretion, prescribe additional
conditions to the exercise of any such tandem SAR.

    (c) Amount of Payment Upon Exercise of SARs.  A SAR shall entitle the
grantee to receive, subject to the provisions of the Plan and the Grant
Agreement, a payment having an aggregate value equal to the product of (i) the
excess of (A) the Fair Market Value on the exercise date of one share of Common
Stock over (B) the base price per share specified in the Grant Agreement, times
(ii) the number of shares specified by the SAR, or portion thereof, which is
exercised.  In the case of exercise of a tandem SAR, such payment shall be made
in exchange for the surrender of the unexercised related stock option (or any
portion or portions thereof which the grantee from time to time determines to
surrender for this purpose).

    (d) Form of Payment Upon Exercise of SARs.  Payment by the Corporation of
the amount receivable upon any exercise of a SAR may be made by the delivery of
Common Stock or cash, or any combination of Common Stock and cash, as determined
in the sole discretion of the Committee from time to time.  If upon settlement
of the exercise of a SAR a grantee is to receive a portion of such payment in
shares of Common Stock, the number of shares shall be determined by dividing
such portion by the Fair Market Value of a share of Common Stock on the exercise
date.  No fractional shares shall be used for such payment and the Committee
shall determine whether cash shall be given in lieu of such fractional shares or
whether such fractional shares shall be eliminated.

8.  Stock Awards (Including Restricted and Unrestricted Shares and Phantom
    Stock)

    (a) Stock Awards, In General.  Subject to the other applicable provisions
of the Plan, the Committee may at any time and from time to time grant stock
Awards to eligible participants in such amounts and for such consideration,
including no consideration or such minimum consideration as may be required by
law, as it determines.  A stock Award may be denominated in shares of Common
Stock or stock-equivalent units ("phantom stock"), and may be paid in Common
Stock, in cash, or in a combination of Common Stock and cash, as determined in
the sole discretion of the Committee from time to time.

    (b) Restricted Shares.  Each stock Award shall specify the applicable
restrictions, if any, on such shares of Common Stock, the duration of such
restrictions,

                                      -8-
<PAGE>

and the time or times at which such restrictions shall lapse with respect to all
or a specified number of shares of Common Stock that are part of the Award.
Notwithstanding the foregoing, the Committee may reduce or shorten the duration
of any restriction applicable to any shares of Common Stock awarded to any
grantee under the Plan. Share certificates with respect to restricted shares of
Common Stock granted pursuant to a stock Award may be issued at the time of
grant of the stock Award, subject to forfeiture if the restrictions do not
lapse, or upon lapse of the restrictions. If share certificates are issued at
the time of grant of the stock Award, the certificates shall bear an appropriate
legend with respect to the restrictions applicable to such stock Award or,
alternatively, the grantee may be required to deposit the certificates with the
Corporation during the period of any restriction thereon and to execute a blank
stock power or other instrument of transfer therefor. Except as otherwise
provided by the Committee, during such period of restriction following issuance
of share certificates, the grantee shall have all of the rights of a holder of
Common Stock, including but not limited to the rights to receive dividends (or
amounts equivalent to dividends) and to vote with respect to the restricted
shares. If share certificates are issued upon lapse of restrictions on a stock
Award, the Committee may provide that the grantee will be entitled to receive
any amounts per share pursuant to any dividend or distribution paid by the
Corporation on its Common Stock to stockholders of record after grant of the
stock Award and prior to the issuance of the share certificates.

    (c) Phantom Stock.  The grant of phantom stock units shall be evidenced by
a Grant Agreement, executed by the Corporation and the grantee, that
incorporates the terms of the Plan and states the number of phantom stock units
evidenced thereby and the terms and conditions of such phantom stock units in
such form as the Committee may from time to time determine.  Phantom stock units
granted to a participant shall be credited to a bookkeeping reserve account
solely for accounting purposes and shall not require a segregation of any of the
Corporation's assets.  Phantom stock units may be exercised in whole or in part
by delivery of an appropriate exercise notice to the Committee in accordance
with the provisions of the Grant Agreement, and/or such rules and regulations as
the Committee may prescribe, and/or such determinations, orders, or decisions as
the Committee may make.  Except as otherwise provided in the applicable Grant
Agreement, the grantee shall have none of the rights of a stockholder with
respect to any shares of Common Stock represented by a phantom stock unit as a
result of the grant of a phantom stock unit to the grantee.  Phantom stock units
may contain such other provisions, not inconsistent with the provisions of the
Plan, as the Committee shall determine appropriate from time to time.

9.  Performance Awards

    The Committee may in its discretion grant performance Awards which become
payable on account of attainment of one or more performance goals established by
the Committee.  Performance Awards may be paid by the delivery of Common Stock
or cash, or any combination of Common Stock and cash, as determined in the sole
discretion of the Committee from time to time.  Performance goals established by
the Committee may

                                      -9-
<PAGE>

be based on the Corporation's operating income or one or more other business
criteria selected by the Committee that apply to an individual or group of
individuals, a business unit, or the Corporation as a whole, over such
performance period as the Committee may designate. The Committee in its
discretion may recommend to the Board of Directors of the Corporation that the
material terms of any Performance Award or program with respect to some or all
eligible participants be submitted for approval by the stockholders.

10. Withholding of Taxes

    The Corporation may require, as a condition to the grant of any Award under
the Plan or exercise pursuant to such Award or to the delivery of certificates
for shares issued or payments of cash to a grantee pursuant to the Plan or a
Grant Agreement (hereinafter collectively referred to as a "taxable event"),
that the grantee pay to the Corporation, in cash or, unless otherwise determined
by the Corporation, in shares of Common Stock, including shares acquired upon
grant of the Award or exercise of the Award, 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.

11. Transferability

    No Award granted under the Plan shall be transferable by a grantee
otherwise 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 Award 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.

12. 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 Awards 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 Awards made under the Plan, and in any other matters which relate to
Awards and which are affected by the changes in the Common Stock referred to
above.

                                     -10-
<PAGE>

    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 Awards, 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 Award to require that
exercise be made, if at all, prior to the Change in Control; (ii) cancellation
of any Award upon payment to the holder in cash of the Fair Market Value of the
Common Stock subject to such Award 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 Award; 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 Awards granted hereunder with awards with respect to
such other securities, with appropriate adjustments in the number of shares
subject to, and the exercise prices under, the award.

    The Committee is authorized to make adjustments in the terms and conditions
of, and the criteria included in, Awards in recognition of unusual or
nonrecurring events (including, without limitation, the events described in the
preceding two paragraphs of this Section 12) affecting the Corporation, or the
financial statements of the Corporation or any Subsidiary, or of changes in
applicable laws, regulations, or accounting principles, whenever the Committee
determines that such adjustments are appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan.

    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, stock appreciation right or restricted stock Award:
(i) each grantee shall have the right to exercise his stock option or stock
appreciation right, or to require delivery of share certificates representing
any such restricted stock Award, 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, stock
appreciation right or restricted stock Award 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 or stock appreciation right not so exercised, canceled, or
surrendered shall terminate on the last day for exercise prior to such effective
date; and any restricted stock as to which there has not been such delivery of
share certificates or that has not been so canceled or surrendered, shall be
forfeited on the last day prior to such effective date.  The Committee shall
give to each grantee written notice of the commencement of any proceedings for
such liquidation and dissolution of the Corporation and the grantee's rights
with respect to his outstanding Award.

                                     -11-
<PAGE>

    Except as hereinbefore 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 Awards theretofore granted or the purchase
price per share of Common Stock subject to Awards.

13. 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 to increase the number of shares of Common Stock subject to
the Plan or 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 (including for this purpose stockholder
approval that is required for continued compliance with Rule 16b-3 or
stockholder approval that is required to enable the Committee to grant incentive
stock options pursuant to the Plan).

    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 Award in any manner to the extent
that the Committee would have had the authority to make such Award as so
modified or amended.  No modification may be made that would materially
adversely affect any Award previously made under the Plan without the approval
of the grantee.

14. 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.

15. Termination of Employment

    For purposes of maintaining a grantee's continuous status as an employee
and accrual of rights under any Award, 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.

                                     -12-
<PAGE>

16.  Written Agreement

     Each Grant Agreement entered into between the Corporation and a grantee
with respect to an Award 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.

17.  Non-Uniform Determinations

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

18.  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.

19.  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 Award 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 Award may be exercised in
whole or in part and no restrictions on such Award shall lapse, unless such
listing, registration or qualification is effected free of any conditions not
acceptable to the Corporation.

20.  Compliance with Securities Law

     The Corporation may require that a grantee, as a condition to exercise of
an Award, and as a condition to the delivery of any share certificate, provide
to the Corporation, at the time of each such exercise and each such delivery, a
written representation that the shares of Common Stock being acquired shall be
acquired by the grantee solely for investment and will not be sold or
transferred without registration or the availability of an exemption from
registration under the Securities Act and applicable state securities laws.  The
Corporation may also require that a grantee submit other written representations
which will permit the Corporation to comply with federal and

                                     -13-
<PAGE>

applicable state securities laws in connection with the issuance of the Common
Stock, including representations as to the knowledge and experience in financial
and business matters of the grantee and the grantee's ability to bear the
economic risk of the grantee's investment. The Corporation may require that the
grantee obtain a "purchaser representative" as that term is defined in
applicable federal and state securities laws. The stock certificates for any
shares of Common Stock issued pursuant to this Plan may bear a legend
restricting transferability of the shares of Common Stock unless such shares are
registered or an exemption from registration is available under the Securities
Act and applicable state securities laws. The Corporation may notify its
transfer agent to stop any transfer of shares of Common Stock not made in
compliance with these restrictions. Common Stock shall not be issued with
respect to an Award granted under the Plan unless the exercise of such Award 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, 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.

21.  No Trust or Fund Created

     Neither the Plan nor any Award 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 payments from the Corporation
pursuant to an Award, such right shall be no greater than the right of any
unsecured general creditor of the Corporation.

22.  No Limit on Other Compensation Arrangements

     Nothing contained in the Plan shall prevent the Corporation or its Parent
or Subsidiary corporations from adopting or continuing in effect other
compensation arrangements (whether such arrangements be generally applicable or
applicable only in specific cases) as the Committee in its discretion determines
desirable, including without limitation the granting of stock options, stock
awards, stock appreciation rights or phantom stock units otherwise than under
the Plan.

23.  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 Award 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.

                                     -14-
<PAGE>

24.  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 Maryland, without
regard to its conflict of laws rules and principles.

25.  Plan Subject to Charter and By-Laws

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

26.  Effective Date; Termination Date

     The Plan is effective as of the date on which the Plan was adopted by the
Board; provided that no stock options issued hereunder shall be treated as
incentive stock options, regardless of the designation in the Grant Agreement,
unless the Plan is approved by the shareholders of the Corporation as provided
in Section 6(e)(vi).  No Award 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 Awards made under the Plan prior to such termination of the Plan shall
remain in effect until such Awards have been satisfied or terminated in
accordance with the Plan and the terms of such Awards.

Date Approved by the Board:   June 30, 2000
