SECTION 1.     INTRODUCTION.

        The Company's Board of Directors adopted the Connex, Inc. 1999 Stock
Incentive Plan on November 8, 1999, subject to approval by the Company's
stockholder.

        The purpose of the Plan is to promote the long-term success of the
Company and the creation of stockholder value by offering Key Employees an
opportunity to acquire a proprietary interest in the success of the Company, or
to increase such interest, and to encourage such selected persons to continue to
provide services to the Company and to attract new individuals with outstanding
qualifications.

        The Plan seeks to achieve this purpose by providing for Awards in the
form of Restricted Stock, Stock Units, Options (which may constitute Incentive
Stock Options or Nonstatutory Stock Options) or Stock Appreciation Rights.

        The Plan shall be governed by, and construed in accordance with, the
laws of the State of Delaware (except its choice-of-law provisions). Capitalized
terms shall have the meaning provided in Section 2 unless otherwise provided in
this Plan, or in the applicable Stock Award Agreement, SAR Agreement or Stock
Option Agreement.

<PAGE>   9
directors of the Company under Section 16 of the Exchange Act, may grant Awards
under the Plan to such Key Employees and may determine all terms of such Awards.

        (b) AUTHORITY OF THE COMMITTEE. Subject to the provisions of the Plan,

        The Committee may adopt such rules or guidelines as it deems appropriate
to implement the Plan. The Committee's determinations under the Plan shall be

        (c) FINANCIAL REPORTS. To the extent required by applicable law, and not
less often than annually, the Company shall furnish to Optionees the Company's
summary financial information including a balance sheet regarding the Company's
financial condition and results of operations, unless such Optionees have duties
with the Company that assure them access to equivalent information. Such
financial statements need not be audited.

SECTION 4.     ELIGIBILITY.

        (a) GENERAL RULES. Only Employees, Directors, Non-Employee Directors and
Consultants shall be eligible for designation as Key Employees by the Committee.

        (b) INCENTIVE STOCK OPTIONS. Only Key Employees who are common-law
employees of the Company, its Parent or a Subsidiary shall be eligible for the
grant of ISOs. In addition, a Key Employee who is a 10-Percent Stockholder shall
not be eligible for the grant of an ISO unless the requirements set forth in
section 422(c)(5) of the Code are satisfied.

SECTION 5.     SHARES SUBJECT TO PLAN.

        (a) BASIC LIMITATION. The stock issuable under the Plan shall be
authorized but unissued Shares or treasury Shares. The aggregate number of
Shares reserved for Awards under the Plan shall not exceed 10,000,000 Shares on
a fully diluted basis, subject to adjustment pursuant to Section 10.

        (b) ADDITIONAL SHARES. If Stock Units, Options or SARs are forfeited or
if Options or SARs terminate for any other reason before being exercised, then
such Stock Units, Options or SARs shall again become available for Awards under
the Plan. If SARs are exercised, then only the number of Shares (if any)
actually issued in settlement of such SARs shall reduce the number available
under Section 5(a) and the balance shall again become available for Awards under
the



                                       6


<PAGE>   10
Plan. If Restricted Stock is forfeited, then such Restricted Stock shall again
become available for Awards under the Plan.

        (c) DIVIDEND EQUIVALENTS. Any dividend equivalents distributed under the
Plan shall not be applied against the number of Restricted Stock, Stock Units,
Options or SARs available for Awards, whether or not such dividend equivalents
are converted into Stock Units.

SECTION 6.     TERMS AND CONDITIONS FOR AWARDS OF RESTRICTED STOCK AND STOCK
               UNITS.

        (a) TIME, AMOUNT AND FORM OF AWARDS. Awards under the Plan may be
granted in the form of Restricted Stock, in the form of Stock Units, or in any
combination of both. Restricted Stock or Stock Units may also be awarded in
combination with NSOs or SARs, and such an Award may provide that the Restricted
Stock or Stock Units will be forfeited in the event that the related NSOs or
SARs are exercised.

        (b) PAYMENT FOR AWARDS. Except as may be required under applicable law,
no cash consideration shall be required of the recipients of Restricted Stock or
Stock Units under this Section 6.

        (c) VESTING CONDITIONS. Each Award of Restricted Stock or Stock Units
shall become vested, in full or in installments, upon satisfaction of the
conditions specified in the Stock Award Agreement. A Stock Award Agreement may
provide for accelerated vesting in the event of the Participant's death,
Disability or retirement or other events. Except as may be otherwise provided in
a particular Stock Award Agreement, in the event of a Change in Control, each
outstanding Award of Restricted Stock or Stock Units shall be assumed or an
equivalent award shall be substituted by the successor corporation or a Parent
or Subsidiary of such successor corporation, unless such successor corporation
does not agree to assume the outstanding Awards of Restricted Stock or Stock
Units, in which case such Awards of Restricted Stock and Stock Units shall
terminate upon the consummation of the transaction.

        For purposes of this Section 6(c), an Award of Restricted Stock or Stock
Units shall be considered assumed, without limitation, if, at the time of
issuance of the stock or other consideration upon a Change in Control, each
holder of Restricted Stock or Stock Units would be entitled to purchase the same
number and kind of shares of stock or the same amount of property, cash or
securities as such holder would have been entitled to receive upon the
occurrence of the transaction if the holder had been, immediately prior to such
transaction, the holder of the number of Shares of Common Stock covered by the
Stock Award Agreement at such time (after giving effect to any adjustments in
the number of Shares covered by the Stock Award Agreement as provided for in
Section 10); provided however that if such consideration received in the
transaction is not solely common stock of the successor corporation or its
Parent, the Committee may, with the consent of the successor corporation,
provide for the consideration to be purchased under the Stock Award Agreement to
be solely common stock of the successor corporation or its Parent equal to the
Fair Market Value of the per Share consideration received by holders of Common
Stock in the transaction.

<PAGE>   11
        (d) FORM AND TIME OF SETTLEMENT OF STOCK UNITS. Settlement of vested
Stock Units may be made in the form of (i) cash, (ii) Shares or (iii) any
combination of both. The actual number of Stock Units eligible for settlement
may be larger or smaller than the number included in the original Award, based
on predetermined performance factors. Methods of converting Stock Units into
cash may include (without limitation) a method based on the average Fair Market
Value of Shares over a series of trading days. Vested Stock Units may be settled
in a lump sum or in installments. The distribution may occur or commence when
all vesting conditions applicable to the Stock Units have been satisfied or have
lapsed, or it may be deferred to any later date. The amount of a deferred
distribution may be increased by an interest factor or by dividend equivalents.
Until an Award of Stock Units is settled, the number of such Stock Units shall
be subject to adjustment pursuant to Section 10.

        (e) DEATH OF RECIPIENT. Any Stock Units Award that becomes payable after
the Award recipient's death shall be distributed to the recipient's beneficiary
or beneficiaries. Each recipient of a Stock Units Award under the Plan shall
designate one or more beneficiaries for this purpose by filing the prescribed
form with the Company. A beneficiary designation may be changed by filing the
prescribed form with the Company at any time before the recipient's death. If no
beneficiary was designated or if no designated beneficiary survives the
recipient, then any Stock Units Award that becomes payable after the recipient's
death shall be distributed to the recipient's estate.

        (f) CREDITORS' RIGHTS. A holder of Stock Units shall have no rights
other than those of a general creditor of the Company. Stock Units represent an
unfunded and unsecured obligation of the Company, subject to the terms and
conditions of the applicable Stock Award Agreement.

SECTION 7.     TERMS AND CONDITIONS OF OPTIONS.

        (a) STOCK OPTION AGREEMENT. Each Grant under the Plan shall be evidenced
by a Stock Option Agreement between the Optionee and the Company. Such Option
shall be subject to all applicable terms and conditions of the Plan and may be
subject to any other terms and conditions that are not inconsistent with the
Plan and that the Committee deems appropriate for inclusion in a Stock Option
Agreement. The provisions of the various Stock Option Agreements entered into
under the Plan need not be identical. A Stock Option Agreement may provide that
new Options will be granted automatically to the Optionee when he or she
exercises the prior Options. The Stock Option Agreement shall also specify
whether the Option is an ISO or an NSO.

        (b) NUMBER OF SHARES. Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 10.

        (c) EXERCISE PRICE. An Option's Exercise Price shall be established by
the Committee and set forth in a Stock Option Agreement. The Exercise Price of
an ISO shall not be less than 100% of the Fair Market Value (110% for 10-Percent
Stockholders) of a Share on the date of Grant. In the case of an NSO, a Stock
Option Agreement may specify an Exercise Price that varies in accordance with a
predetermined formula while the NSO is outstanding. To the


                                       8


<PAGE>   12
extent required by applicable law, the Exercise Price for an NSO shall not be
less than 85% of the Fair Market Value (110% for 10-Percent Stockholders) of a
Share on the date of Grant.

        (d) EXERCISABILITY AND TERM. Each Stock Option Agreement shall specify
the date when all or any installment of the Option is to become exercisable. To
the extent required by applicable law, Options shall vest at least as rapidly as
20% annually over a five-year period. The Stock Option Agreement shall also
specify the term of the Option; provided that the term of an ISO, and to the
extent required by applicable law a NSO, shall in no event exceed ten (10) years
from the date of Grant (five (5) years for ISO Grants to 10-Percent
Stockholders). To the extent required by applicable law, Options shall be
exercisable for a minimum period of six months following termination of
employment due to death or Disability and thirty days following termination of
employment (other than terminations for cause, as defined in the Company's
personnel policies). Notwithstanding the previous sentence, no Option can be
exercised after the expiration date provided in the applicable Stock Option
Agreement. A Stock Option Agreement may provide for accelerated exercisability
in the event of the Optionee's death, Disability or retirement or other events
and may provide for expiration prior to the end of its term in the event of the
termination of the Optionee's Service. Options may be awarded in combination
with SARs, and such an Award may provide that the Options will not be
exercisable unless the related SARs are forfeited. NSOs may also be awarded in
combination with Restricted Stock or Stock Units, and such an Award may provide
that the NSOs will not be exercisable unless the related Restricted Stock or
Stock Units are forfeited. A Stock Option Agreement may permit an Optionee to
exercise an Option before it is vested, subject to the Company's right of
repurchase over any Shares acquired under the unvested portion of the Option (an
"early exercise"), which right of repurchase shall lapse at the same rate the
Option would have vested had there been no early exercise. In no event shall the
Company be required to issue fractional Shares upon the exercise of an Option.

        (e) EFFECT OF A CHANGE IN CONTROL. Except as may be otherwise provided
in a particular Stock Option Agreement, in the event of a Change in Control,
each outstanding Option shall be assumed or an equivalent option or right shall
be substituted by the successor corporation or a Parent or Subsidiary of such
successor corporation, unless such successor corporation does not agree to
assume the outstanding Options, in which case such Options shall terminate upon
the consummation of the transaction.

        For purposes of this Section 7(e), an Option shall be considered
assumed, without limitation, if, at the time of issuance of the stock or other
consideration upon a Change in Control, each holder of an Option would be
entitled to receive upon exercise of the Option the same number and kind of
shares of stock or the same amount of property, cash or securities as such
holder would have been entitled to receive upon the occurrence of the
transaction if the holder had been, immediately prior to such transaction, the
holder of the number of Shares of Common Stock covered by the Option at such
time (after giving effect to any adjustments in the number of Shares covered by
the Option as provided for in Section 10); provided however that if such
consideration received in the transaction is not solely common stock of the
successor corporation or its Parent, the Committee may, with the consent of the
successor corporation, provide for the consideration to be received upon
exercise of the Option to be solely common stock of the successor corporation or
its Parent equal to the Fair Market Value of the per Share consideration
received by holders of Common Stock in the transaction.


                                       9


<PAGE>   13
        (f) MODIFICATIONS OR ASSUMPTION OF OPTIONS. Within the limitations of
the Plan, the Committee may modify, extend or assume outstanding Options or may
accept the cancellation of outstanding options (whether granted by the Company
or by another issuer) in return for the grant of new Options for the same or a
different number of Shares and at the same or a different Exercise Price. The
foregoing notwithstanding, no modification of an Option shall, without the
consent of the Optionee, alter or impair his or her rights or obligations under
such Option.

        (g) TRANSFERABILITY OF OPTIONS. Except as otherwise provided in the
applicable Stock Option Agreement and then only to the extent permitted by
applicable law, no Option shall be transferable by the Optionee other than by
will or by the laws of descent and distribution. Except as otherwise provided in
the applicable Stock Option Agreement, an Option may be exercised during the
lifetime of the Optionee only by the Optionee or by the guardian or legal
representative of the Optionee. No Option or interest therein may be assigned,
pledged or hypothecated by the Optionee during his lifetime, whether by
operation of law or otherwise, or be made subject to execution, attachment or
similar process.

        (h) NO RIGHTS AS A STOCKHOLDER. An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by an Option until such person becomes entitled to receive such Shares
by filing a notice of exercise and paying the Exercise Price pursuant to the
terms of such Option.

        (i) RESTRICTIONS ON TRANSFER. Any Shares issued upon exercise of an
Option shall be subject to such rights of repurchase, rights of first refusal
and other transfer restrictions as the Committee may determine. Such
restrictions shall apply in addition to any restrictions that may apply to
holders of Shares generally and shall also comply to the extent necessary with
applicable law.

SECTION 8.     PAYMENT FOR OPTION SHARES.

        (a) GENERAL RULE. The entire Exercise Price of Shares issued upon
exercise of Options shall be payable in cash at the time when such Shares are
purchased, except as follows:

                (i) In the case of an ISO granted under the Plan, payment shall
        be made only pursuant to the express provisions of the applicable Stock
        Option Agreement. The Stock Option Agreement may specify that payment
        may be made in any form(s) described in this Section 8.

                (ii) In the case of an NSO, the Committee may at any time accept
        payment in any form(s) described in this Section 8.

        (b) SURRENDER OF STOCK. To the extent that this Section 8(b) is
applicable, payment for all or any part of the Exercise Price may be made with
Shares which have already been owned by the Optionee for such duration as shall
be specified by the Committee. Such Shares shall be valued at their Fair Market
Value on the date when the new Shares are purchased under the Plan.

        (c) PROMISSORY NOTE. To the extent that this Section 8(c) is applicable,
payment for all or any part of the Exercise Price may be made with a full
recourse promissory note.


                                       10


<PAGE>   14
        (d) OTHER FORMS OF PAYMENT. To the extent that this Section 8(d) is
applicable, payment may be made in any other form that is consistent with
applicable laws, regulations and rules.

SECTION 9.     STOCK APPRECIATION RIGHTS.

        (a) SAR AGREEMENT. To the extent permitted under applicable law, the
Committee may grant Awards which are SARs. Each grant of a SAR under the Plan
shall be evidenced by a SAR Agreement between the Optionee and the Company. Such
SAR shall be subject to all applicable terms of the Plan and may be subject to
any other terms that are not inconsistent with the Plan. The provisions of the
various SAR Agreements entered into under the Plan need not be identical. SARs
may be granted in consideration of a reduction in the Optionee's other
compensation.

        (b) NUMBER OF SHARES. Each SAR Agreement shall specify the number of
Shares to which the SAR pertains and shall provide for the adjustment of such
number in accordance with Section 10.

        (c) EXERCISE PRICE. Each SAR Agreement shall specify the Exercise Price.
A SAR Agreement may specify an Exercise Price that varies in accordance with a
predetermined formula while the SAR is outstanding.

        (d) EXERCISABILITY AND TERM. Each SAR Agreement shall specify the date
when all or any installment of the SAR is to become exercisable. The SAR
Agreement shall also specify the term of the SAR. A SAR Agreement may provide
for accelerated exercisability in the event of the Optionee's death, Disability
or retirement or other events and may provide for expiration prior to the end of
its term in the event of the termination of the Optionee's Service. SARs may
also be awarded in combination with Options, Restricted Stock or Stock Units,
and such an Award may provide that the SARs will not be exercisable unless the
related Options, Restricted Stock or Stock Units are forfeited. A SAR may be
included in an ISO only at the time of Grant but may be included in an NSO at
the time of Grant or at any subsequent time, but not later than six months
before the expiration of such NSO. A SAR granted under the Plan may provide that
it will be exercisable only in the event of a Change in Control.

        (e) EFFECT OF CHANGE IN CONTROL. Except as may be otherwise provided in
a particular SAR Agreement, in the event of a Change in Control, each
outstanding SAR shall be assumed or an equivalent option or right shall be
substituted by the successor corporation or a Parent or Subsidiary of such
successor corporation, unless such successor corporation does not agree to
assume the outstanding SARs, in which case such SARs shall terminate upon the
consummation of the transaction.

        For purposes of this Section 9(e), a SAR shall be considered assumed,
without limitation, if, at the time of issuance of the stock or other
consideration upon a Change in Control, each holder of a SAR would be entitled
to receive upon exercise of the SAR the same number and kind of shares of stock
or the same amount of property, cash or securities as such holder would have
been entitled to receive upon the occurrence of the transaction if the holder
had been, immediately prior to such transaction, the holder of the number of
Shares of Common Stock


                                       11


<PAGE>   15
covered by the SAR at such time (after giving effect to any adjustments in the
number of Shares covered by the SAR as provided for in Section 10); provided
however that if such consideration received in the transaction is not solely
common stock of the successor corporation or its Parent, the Committee may, with
the consent of the successor corporation, provide for the consideration to be
received upon exercise of the SAR to be solely common stock of the successor
corporation or its Parent equal to the Fair Market Value of the per Share
consideration received by holders of Common Stock in the transaction.

        (f) EXERCISE OF SARS. If, on the date when a SAR expires, the Exercise
Price under such SAR is less than the Fair Market Value on such date but any
portion of such SAR has not been exercised or surrendered, then such SAR shall
automatically be deemed to be exercised as of such date with respect to such
portion. Upon exercise of a SAR, the Optionee (or any person having the right to
exercise the SAR after his or her death) shall receive from the Company (i)
Shares, (ii) cash or (iii) a combination of Shares and cash, as the Committee
shall determine. The amount of cash and/or the Fair Market Value of Shares
received upon exercise of SARs shall, in the aggregate, be equal to the amount
by which the Fair Market Value (on the date of surrender) of the Shares subject
to the SARs exceeds the Exercise Price.

        (g) MODIFICATION OR ASSUMPTION OF SARS. Within the limitations of the
Plan, the Committee may modify, extend or assume outstanding SARs or may accept
the cancellation of outstanding SARs (whether granted by the Company or by
another issuer) in return for the grant of new SARs for the same or a different
number of Shares and at the same or a different Exercise Price. The foregoing
notwithstanding, no modification of a SAR shall, without the consent of the
Optionee, alter or impair his or her rights or obligations under such SAR.

SECTION 10.    PROTECTION AGAINST DILUTION.

        (a) ADJUSTMENTS. In the event of a subdivision of the outstanding
Shares, a declaration of a dividend payable in Shares, a declaration of a
dividend payable in a form other than Shares in an amount that has a material
effect on the price of Shares, a combination or consolidation of the outstanding
Shares (by reclassification or otherwise) into a lesser number of Shares, a
recapitalization, a spinoff or a similar occurrence, the Committee shall make
such adjustments as it, in its sole discretion, deems appropriate in one or more
of:

                (i) the number of Options, SARs, Restricted Stock and Stock
        Units available for future Awards under Section 5;

                (ii) the number of Stock Units included in any prior Award which
        has not yet been settled;

                (iii) the number of Shares covered by each outstanding Option
        and SAR; or

                (iv) the Exercise Price under each outstanding Option and SAR.

Except as provided in this Section 10, a Participant shall have no rights by
reason of any issue by the Company of stock of any class or securities
convertible into stock of any class, any subdivision or consolidation of shares
of stock of any class, the payment of any stock dividend or any other increase
or decrease in the number of shares of stock of any class.


                                       12


<PAGE>   16
        (b) REORGANIZATIONS. In the event that the Company is a party to a
merger or other reorganization, outstanding Options, SARs, Restricted Stock and
Stock Units shall be subject to the agreement of merger or reorganization. Such
agreement may provide, without limitation, for the assumption of outstanding
Awards by the surviving corporation or its Parent or for their continuation by
the Company (if the Company is a surviving corporation), for accelerated vesting
and accelerated expiration, or for settlement in cash or for cancellation.

SECTION 11.    VOTING AND DIVIDEND RIGHTS.

        (a) RESTRICTED STOCK. The holders of Restricted Stock awarded under the
Plan shall have the same voting, dividend and other rights as the Company's
other stockholders. A Stock Award Agreement, however, may require that the
holders of Restricted Stock invest any cash dividends received in additional
Restricted Stock. Such additional Restricted Stock shall be subject to the same
conditions and restrictions as the Award with respect to which the dividends
were paid. Such additional Restricted Stock shall not reduce the number of
Shares available under Section 5.

        (b) STOCK UNITS. The holders of Stock Units shall have no voting rights.
Prior to settlement or forfeiture, any Stock Unit awarded under the Plan may, at
the Committee's discretion, carry with it a right to dividend equivalents. Such
right entitles the holder to be credited with an amount equal to all cash
dividends paid on one Share while the Stock Unit is outstanding. Dividend
equivalents may be converted into additional Stock Units. Settlement of dividend
equivalents may be made in the form of cash, in the form of Shares, or in a
combination of both. Prior to distribution, any dividend equivalents which are
not paid shall be subject to the same conditions and restrictions as the Stock
Units to which they attach.

SECTION 12.    AWARDS UNDER OTHER PLANS.

        The Company may grant awards under other plans or programs. Such awards
may be settled in the form of Shares issued under this Plan. Such Shares shall
be treated for all purposes under the Plan like Shares issued in settlement of
Stock Units and shall, when issued, reduce the number of Shares available under
Section 5.

SECTION 13.    LIMITATIONS ON RIGHTS.

        (a) RETENTION RIGHTS. Neither the Plan nor any Award granted under the
Plan shall be deemed to give any individual a right to remain an employee,
consultant or director of the Company, a Parent, a Subsidiary or an Affiliate.
The Company and its Parents and Subsidiaries and Affiliates reserve the right to
terminate the Service of any person at any time, and for any reason, subject to
applicable laws, the Company's articles of incorporation and bylaws and a
written employment agreement (if any).

        (b) STOCKHOLDERS' RIGHTS. A Participant shall have no dividend rights,
voting rights or other rights as a stockholder with respect to any Shares
covered by his or her Award prior to the issuance of a stock certificate for
such Shares. No adjustment shall be made for cash dividends or other rights for
which the record date is prior to the date when such certificate is issued,
except as expressly provided in Sections 6, 10 and 11.


                                       13


<PAGE>   17
        (c) REGULATORY REQUIREMENTS. Any other provision of the Plan
notwithstanding, the obligation of the Company to issue Shares under the Plan
shall be subject to all applicable laws, rules and regulations and such approval
by any regulatory body as may be required. The Company reserves the right to
restrict, in whole or in part, the delivery of Shares pursuant to any Award
prior to the satisfaction of all legal requirements relating to the issuance of
such Shares, to their registration, qualification or listing or to an exemption
from registration, qualification or listing.

SECTION 14.    WITHHOLDING TAXES.

        (a) GENERAL. To the extent required by applicable federal, state, local
or foreign law, a Participant or his or her successor shall make arrangements
satisfactory to the Company for the satisfaction of any withholding tax
obligations that arise in connection with the Plan. The Company shall not be
required to issue any Shares or make any cash payment under the Plan until such
obligations are satisfied.

        (b) SHARE WITHHOLDING. If a public market for the Company's Shares
exists, the Committee may permit a Participant to satisfy all or part of his or
her withholding or income tax obligations by having the Company withhold all or
a portion of any Shares that otherwise would be issued to him or her or by
surrendering all or a portion of any Shares that he or she previously acquired.
Such Shares shall be valued at their Fair Market Value on the date when taxes
otherwise would be withheld in cash. Any payment of taxes by assigning Shares to
the Company may be subject to restrictions, including any restrictions required
by rules of the Securities and Exchange Commission.

SECTION 15.    ASSIGNMENT OR TRANSFER OF AWARDS.

        (a) GENERAL. Except as provided in Section 14, or in an applicable
agreement, or as required by applicable law, an Award granted under the Plan
shall not be anticipated, assigned, attached, garnished, optioned, transferred
or made subject to any creditor's process, whether voluntarily, involuntarily or
by operation of law. An Option or SAR may be exercised during the lifetime of
the Optionee only by him or her or by his or her guardian or legal
representative. Any act in violation of this Section 15 shall be void. However,
this Section 15 shall not preclude a Participant from designating a beneficiary
who will receive any outstanding Awards in the event of the Participant's death,
nor shall it preclude a transfer of Awards by will or by the laws of descent and
distribution.

        (b) TRUSTS. Neither this Section 15 nor any other provision of the Plan
shall preclude a Participant from transferring or assigning Restricted Stock or
Stock Units to (a) the trustee of a trust that is revocable by such Participant
alone, both at the time of the transfer or assignment and at all times
thereafter prior to such Participant's death, or (b) the trustee of any other
trust to the extent approved in advance by the Committee in writing. A transfer
or assignment of Restricted Stock or Stock Units from such trustee to any person
other than such Participant shall be permitted only to the extent approved in
advance by the Committee in writing, and Restricted Stock or Stock Units held by
such trustee shall be subject to all of the conditions and restrictions set
forth in the Plan and in the applicable Stock Award Agreement, as if such
trustee were a party to such Agreement.

SECTION 16.    DURATION AND AMENDMENTS.

        (a) TERM OF THE PLAN. The Plan, as set forth herein, shall become
effective on the date of its adoption by the Board, subject to the approval of
the Company's stockholder. No Awards shall be exercisable until such stockholder
approval is obtained. In the event that the stockholder fails to approve the
Plan within twelve (12) months after its adoption by the Board, any Awards made
shall be null and void and no additional Awards shall be made after such date.
To the extent required by applicable law, the Plan shall terminate on the date
that is ten (10) years after its adoption by the Board and may be terminated on
any earlier date pursuant to Section 16(b).

        (b) RIGHT TO AMEND OR TERMINATE THE PLAN. The Board may amend or
terminate the Plan at any time and for any reason. The termination of the Plan,
or any amendment thereof, shall not affect any Award previously granted under
the Plan. No Awards shall be granted under the Plan after the Plan's
termination. An amendment of the Plan shall be subject to the approval of the
Company's stockholder(s) only to the extent required by applicable laws,
regulations or rules.

SECTION 17.    EXECUTION.

        To record the adoption of the Plan by the Board, the Company has caused
its duly authorized officer to execute this Plan.
