EXHIBIT 10.38
MERCATOR SOFTWARE, INC.
1997 EMPLOYEE STOCK PURCHASE PLAN
As Adopted May 8, 1997, Amended July 21, 1997,
January 19, 1998, April 1, 1999, October 17, 2000, May 14, 2002
1. Establishment of Plan. Mercator Software, Inc. (the "Company")
proposes to grant options for purchase of the Company's Common Stock to eligible
employees of the Company and its Participating Subsidiaries (as hereinafter
defined) pursuant to this Employee Stock Purchase Plan (this "Plan"). For
purposes of this Plan, "Parent Corporation" and "Subsidiary" (collectively,
"Participating Subsidiaries") shall have the same meanings as "parent
corporation" and "subsidiary corporation" in Sections 424(e) and 424(f),
respectively, of the Internal Revenue Code of 1986, as amended (the "Code").
"Participating Subsidiaries" are Parent Corporations or Subsidiaries that the
Board of Directors of the Company (the "Board") designates from time to time as
corporations that shall participate in this Plan. The Company intends this Plan
to qualify as an "employee stock purchase plan" under Section 423 of the Code
(including any amendments to or replacements of such Section), and this Plan
shall be so construed. Any term not expressly defined in this Plan but defined
for purposes of Section 423 of the Code shall have the same definition herein.
Upon commencement of this Plan through May 13, 2002, a total of 1,500,000 shares
of the Company's Common Stock is reserved for issuance under this Plan. As of
May 14, 2002 and thereafter for the remainder of the term (as defined in Section
21 of this Plan), the number of shares of Common Stock reserved for issuance
under such Plan shall be increased on an annual basis, so that on May 14, 2002
(or any later date to which the 2002 Annual Meeting of Stockholders may be
adjourned) and on each January 1 thereafter there are 1,500,000 shares of Common
Stock reserved for issuance under such Plan (or such lesser number of shares as
may be determined by the Board of Directors) and to ratify such Plan as amended.
The number of shares reserved for issuance under this Plan shall be subject to
adjustments effected in accordance with Section 14 of this Plan.
2. Purpose. The purpose of this Plan is to provide eligible employees
of the Company and Participating Subsidiaries with a convenient means of
acquiring an equity interest in the Company through payroll deductions, to
enhance such employees' sense of participation in the affairs of the Company and
Participating Subsidiaries, and to provide an incentive for continued
employment.
3. Administration. This Plan shall be administered by the Board or by a
committee of not less than two members of the Board appointed to administer this
Plan (the "Committee"). As used in this Plan, references to the "Committee"
shall mean either such committee or the Board, if no committee has been
established. Subject to the provisions of this Plan and the limitations of
Section 423 of the Code or any successor provision in the Code, all questions of
interpretation or application of this Plan shall be determined by the Board and
its decisions shall be final and binding upon all participants. Members of the
Board shall receive no compensation for their services in connection with the
administration of this Plan, other than standard fees as established from time
to time by the Board for services rendered by Board members serving on Board
committees. All expenses incurred in connection with the administration of this
Plan shall be paid by the Company.
4. Eligibility. Any employee of the Company or the Participating
Subsidiaries is eligible to participate in an Offering Period (as hereinafter
defined) under this Plan except the following:
(a) employees who are not employed by the Company or Participating
Subsidiaries before the enrollment cut-off date (approximately 2 weeks prior to
the start of the beginning of such Offering Period), except that employees who
are employed on the effective date of the registration statement filed by the
Company with the Securities and Exchange Commission ("SEC") under the Securities
Act of 1933, as amended (the "Securities Act") registering the initial public
offering of the Company's Common Stock shall be eligible to participate in the
first Offering Period under the Plan;
(b) employees who are customarily employed for less than fifteen
(15) hours per week;
(c) employees who, together with any other person whose stock would
be attributed to such employee pursuant to Section 424(d) of the Code, own stock
or hold options to purchase stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Company or
any of its Participating Subsidiaries or who, as a result of being granted an
option under this Plan with respect to such Offering Period, would own stock or
hold options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of
its Participating Subsidiaries; and
(d) individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors whether or not
reclassified as common law employees, unless the Company or a Participating
Subsidiary withholds or is required to withhold U.S. Federal employment taxes
for such individuals pursuant to Section 3402 of the Code.
5. Offering Dates. The offering periods of this Plan (each, an
"Offering Period") shall be of twelve (12) months duration commencing on
February 1 and August 1 of each year and ending on the next January 31 and July
31 respectively, thereafter; provided, however, that notwithstanding the
foregoing, the first such Offering Period shall commence on the first business
day on which price quotations for the Company's Common Stock are available on
the Nasdaq National Market (the "First Offering Date") and shall end on July 31,
1998. Except for the first Offering Period, each Offering Period shall consist
of two (2) six-month purchase periods (individually, a "Purchase Period") during
which payroll deductions of the participants are accumulated under this Plan.
The first Offering Period shall consist of two Purchase Periods, any of which
may be greater or less than six months as determined by the Committee. The first
business day of each
Offering Period is referred to as the "Offering Date." The last business day of
each Purchase Period is referred to as the "Purchase Date." The Board shall
have the power to change the duration of Offering Periods or Purchase Periods
with respect to offerings without stockholder approval if such change is
announced at least fifteen (15) days prior to the scheduled beginning of the
first Offering Period or Purchase Period to be affected.
6. Participation in this Plan. Eligible employees may become
participants in an Offering Period under this Plan on the first Offering Date
after satisfying the eligibility requirements by delivering a subscription
agreement and enrollment form to the Company's plan administration department or
designee (the "Plan Admin. Department") not later than five (5) business days
before such Offering Date unless a later time for filing the subscription
agreement and enrollment form authorizing payroll deductions is set by the Board
for all eligible employees with respect to a given Offering Period. An eligible
employee who does not deliver a subscription agreement and enrollment form to
the Plan Admin. Department by such date after becoming eligible to participate
in such Offering Period shall not participate in that Offering Period or any
subsequent Offering Period unless such employee enrolls in this Plan by filing a
subscription agreement and enrollment form with the Plan Admin. Department not
later than five (5) business days preceding a subsequent Offering Date. Once an
employee becomes a participant in an Offering Period, such employee will
automatically participate in the Offering Period commencing immediately
following the last day of the prior Offering Period unless the employee
withdraws or is deemed to withdraw from this Plan or terminates further
participation in the Offering Period as set forth in Section 11 below. Such
participant is not required to file any additional subscription agreement or
enrollment form in order to continue participation in this Plan.
7. Grant of Option on Enrollment. Enrollment by an eligible employee in
this Plan with respect to an Offering Period will constitute the grant (as of
the Offering Date) by the Company to such employee of an option to purchase on
the Purchase Date up to that number of shares of Common Stock of the Company
determined by dividing (a) the amount accumulated in such employee's payroll
deduction account during such Purchase Period by (b) the lower of (i)
eighty-five percent (85%) of the fair market value of a share of the Company's
Common Stock on the Offering Date (but in no event less than the par value of a
share of the Company's Common Stock), or (ii) eighty-five percent (85%) of the
fair market value of a share of the Company's Common Stock on the Purchase Date
(but in no event less than the par value of a share of the Company's Common
Stock), provided, however, that the number of shares of the Company's Common
Stock subject to any option granted pursuant to this Plan shall not exceed the
lesser of (a) the maximum number of shares set by the Board pursuant to Section
10(c) below with respect to the applicable Purchase Date, or (b) the maximum
number of shares which may be purchased pursuant to Section 10(b) below with
respect to the applicable Purchase Date. The fair market value of a share of the
Company's Common Stock shall be determined as provided in Section 8 hereof.
8. Purchase Price. The purchase price per share at which a share of
Common Stock will be sold in any Offering Period shall be eighty-five percent
(85%) of the lesser of:
(a) The fair market value on the Offering Date; or
(b) The fair market value on the Purchase Date.
For purposes of this Plan, the term "Fair Market Value" means, as
of any date, the value of a share of the Company's Common Stock determined as
follows:
(a) if such Common Stock is then quoted on the Nasdaq
National Market, its closing price on the Nasdaq
National Market on the date of determination as
reported in The Wall Street Journal;
(b) if such Common Stock is publicly traded and is then
listed on a national securities exchange, its closing
price on the date of determination on the principal
national securities exchange on which the Common Stock
is listed or admitted to trading as reported in The
Wall Street Journal;
(c) if such Common Stock is publicly traded but is not
quoted on the Nasdaq National Market nor listed or
admitted to trading on a national securities exchange,
the average of the closing bid and asked prices on the
date of determination as reported in The Wall Street
Journal; or
(d) if none of the foregoing is applicable, by the Board
in good faith, which in the case of the First Offering
Date will be the price per share at which shares of
the Company's Common Stock are initially offered for
sale to the public by the Company's underwriters in
the initial public offering of the Company's Common
Stock pursuant to a registration statement filed with
the SEC under the Securities Act.
9. Payment Of Purchase Price; Changes In Payroll Deductions; Issuance
Of Shares.
(a) The purchase price of the shares is accumulated by regular
payroll deductions made during each Offering Period. The deductions are made as
a percentage of the participant's compensation in one percent (1%) increments
not less than two percent (2%), nor greater than fifteen percent (15%) or such
lower limit set by the Committee. Compensation shall mean base salary plus
earned and paid commissions and bonuses, provided however, that for purposes of
determining a participant's base salary, any election by such participant to
reduce his or her regular cash remuneration under Sections 125 or 401(k) of the
Code shall be treated as if the participant did not make such election. Payroll
deductions shall commence on the first payday following the Offering Date and
shall continue to the end of the Offering Period unless sooner altered or
terminated as provided in this Plan.
(b) A participant may lower (and, effective for Offering Periods
commencing on or after February 1, 1998, increase) the rate of payroll
deductions during an Offering Period by filing with the Plan Admin. Department a
new authorization for payroll deductions, in which case the new rate shall
become effective for the next payroll period commencing more than fifteen (15)
days after the Plan Admin. Department's receipt of the authorization and shall
continue for the remainder of the Offering Period unless changed as described
below. Such change in the rate of payroll deductions may be made at any time
during an Offering Period, but not more than two (2) decreases and one (1)
increase may be made effective during any Offering Period. A participant may
increase or decrease the rate of payroll deductions for any subsequent Offering
Period by filing with the Plan Admin. Department a new authorization for payroll
deductions not later than fifteen (15) days before the beginning of such
Offering Period.
(c) All payroll deductions made for a participant are credited to
his or her account under this Plan and are deposited with the general funds of
the Company. No interest accrues on the payroll deductions. All payroll
deductions received or held by the Company may be used by the Company for any
corporate purpose, and the Company shall not be obligated to segregate such
payroll deductions.
(d) On each Purchase Date, so long as this Plan remains in effect
and provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall apply
the funds then in the participant's account to the purchase of whole shares of
Common Stock reserved under the option granted to such participant with respect
to the Offering Period to the extent that such option is exercisable on the
Purchase Date. The purchase price per share shall be as specified in Section 8
of this Plan. Any cash remaining in a participant's account after such purchase
of shares shall be refunded to such participant in cash, without interest;
provided, however that any amount remaining in such participant's account on a
Purchase Date which is less than the amount necessary to purchase a whole share
shall be carried forward, without interest, into the next Purchase Period or
Offering Period as the case may be. In the event that this Plan has been
oversubscribed, all funds not used to purchase shares on the Purchase Date shall
be returned to the participant, without interest. No Common Stock shall be
purchased on a Purchase Date on behalf of any employee whose participation in
this Plan has terminated prior to such Purchase Date.
(e) As promptly as practicable after the Purchase Date, the Company
shall issue shares for the participant's benefit representing the shares
purchased upon exercise of his or her option.
(f) During a participant's lifetime, such participant's option to
purchase shares hereunder is exercisable only by him or her. The participant
will have no interest or voting right in shares covered by his or her option
until such option has been exercised.
10. Limitations on Shares to be Purchased.
(a) No participant shall be entitled to purchase stock under this
Plan at a rate which, when aggregated with his or her rights to purchase stock
under all other employee stock purchase plans of the Company or any Subsidiary,
exceeds $25,000 in fair market value, determined as of the Offering Date (or
such other limit as may be imposed by the Code) for each calendar year in which
the employee participates in this Plan.
(b) No more than two hundred percent (200%) of the number of
shares determined by using eighty-five percent (85%) of the fair market value of
a share of the Company's Common Stock on the Offering Date as the denominator
may be purchased by a participant on any single Purchase Date.
(c) No participant shall be entitled to purchase more than the
Maximum Share Amount (as defined below) on any single Purchase Date. Not less
than thirty (30) days prior to the commencement of any Offering Period, the
Committee may, in its sole discretion, set a maximum number of shares which may
be purchased by any employee at any single Purchase Date (hereinafter the
"Maximum Share Amount"). Until otherwise determined by the Committee, there
shall be no Maximum Share Amount. In no event shall the Maximum Share Amount, if
any, exceed the amounts permitted under Section 10(b) above. If a new Maximum
Share Amount is set, then all participants must be notified of such Maximum
Share Amount prior to the commencement of the next Offering Period. Once the
Maximum Share Amount is set, it shall continue to apply with respect to all
succeeding Purchase Dates and Offering Periods unless revised by the Committee
as set forth above.
(d) If the number of shares to be purchased on a Purchase Date by
all employees participating in this Plan exceeds the number of shares then
available for issuance under this Plan, then the Company will make a pro rata
allocation of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Committee shall determine to be equitable. In such event,
the Company shall give written notice of such reduction of the number of shares
to be purchased under a participant's option to each participant affected
thereby.
(e) Any payroll deductions accumulated in a participant's account
which are not used to purchase stock due to the limitations in this Section 10
shall be returned to the participant as soon as practicable after the end of the
applicable Purchase Period, without interest.
11. Withdrawal.
(a) Each participant may withdraw from an Offering Period under
this Plan by signing and delivering to the Plan Admin. Department a written
notice to that effect on a form provided for such purpose. Such withdrawal may
be elected at any time at least fifteen (15) days prior to the end of an
Offering Period.
(b) Upon withdrawal from this Plan, the accumulated payroll
deductions shall be returned to the withdrawn participant, without interest, and
his or her interest in this Plan shall terminate. In the event a participant
voluntarily elects to withdraw from this Plan, he or she may not resume his or
her participation in this Plan during the same Offering Period, but he or she
may participate in any Offering Period under this Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth above for initial participation in
this Plan.
(c) If the purchase price on the first day of any current Offering
Period in which a participant is enrolled is higher than the purchase price on
the first day of any subsequent Offering Period, the Company will automatically
enroll such participant in the subsequent Offering Period. Any funds accumulated
in a participant's account prior to the first day of such subsequent Offering
Period will be applied to the purchase of shares on the Purchase Date
immediately prior to the first day of such subsequent Offering Period. A
participant does not need to file any forms with the Company to automatically be
enrolled in the subsequent Offering Period
12. Termination of Employment. Termination of a participant's
employment for any reason, including retirement, death or the failure of a
participant to remain an eligible employee of the Company or of a Participating
Subsidiary, immediately terminates his or her participation in this Plan. In
such event, the payroll deductions credited to the participant's account will be
returned to him or her or, in the case of his or her death, to his or her legal
representative, without interest. For purposes of this Section 12, an employee
will not be deemed to have terminated employment or failed to remain in the
continuous employ of the Company or of a Participating Subsidiary in the case of
sick leave, military leave, or any other leave of absence approved by the Board;
provided that such leave is for a period of not more than ninety (90) days or
reemployment upon the expiration of such leave is guaranteed by contract or
statute.
13. Return of Payroll Deductions. In the event a participant's interest
in this Plan is terminated by withdrawal, termination of employment or
otherwise, or in the event this Plan is terminated by the Board, the Company
shall promptly deliver to the participant all payroll deductions credited to
such participant's account. No interest shall accrue on the payroll deductions
of a participant in this Plan.
14. Capital Changes. Subject to any required action by the stockholders
of the Company, the number of shares of Common Stock covered by each option
under this Plan which has not yet been exercised and the number of shares of
Common Stock which have been authorized for issuance under this Plan but have
not yet been placed under option (collectively, the "Reserves"), as well as the
price per share of Common Stock covered by each option under this Plan which has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued and outstanding shares of Common Stock of the
Company resulting from a stock split or the payment of a stock dividend (but
only on the Common Stock) or any other increase or decrease in the number of
issued and outstanding shares of Common Stock effected without receipt of any
consideration by the Company; provided, however, that conversion of any
convertible
securities of the Company shall not be deemed to have been "effected without
receipt of consideration." Such adjustment shall be made by the Committee, whose
determination shall be final, binding and conclusive. Except as expressly
provided herein, no issue by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an option.
In the event of the proposed dissolution or liquidation of the Company,
the Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Committee. The Committee may,
in the exercise of its sole discretion in such instances, declare that the
options under this Plan shall terminate as of a date fixed by the Committee and
give each participant the right to exercise his or her option as to all of the
optioned stock, including shares which would not otherwise be exercisable. In
the event of (i) a merger or consolidation in which the Company is not the
surviving corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the options under this Plan are
assumed, converted or replaced by the surviving corporation, which assumption,
conversion or replacement will be binding on all participants), (ii) a merger in
which the Company is the surviving corporation but after which the stockholders
of the Company immediately prior to such merger (other than any stockholder that
merges with the Company in such merger, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (iii) the sale of all or
substantially all of the assets of the Company or (iv) the acquisition, sale, or
transfer of more than 50% of the outstanding shares of the Company by tender
offer or similar transaction, each option under this Plan may be assumed or an
equivalent option may be substituted by such surviving corporation or a parent
or subsidiary of such surviving corporation. In the event such surviving
corporation does not assume or substitute the options under this Plan, (x) this
Plan will terminate upon the consummation of such transaction, unless otherwise
provided by the Committee and (y) the Committee may declare that the options
under this Plan shall terminate as of a date fixed by the Committee and give
each participant the right to exercise his or her option as to all of the
optioned stock. If the Committee makes an option fully exercisable in the event
of a merger, consolidation or sale of assets, the Committee shall notify the
participant that the option shall be fully exercisable for a certain period, and
the option and this Plan will terminate upon the expiration of such period.
The Committee may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, or in the event the Company is consolidated with or merged into any other
corporation.
15. Non-assignability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under this
Plan may be assigned, transferred, pledged or otherwise disposed of in any way
(other than by will, the laws of descent and distribution or as provided in
Section 22 hereof) by the participant. Any such attempt at assignment, transfer,
pledge or other disposition shall be void and without effect.
16. Reports. Individual accounts will be maintained for each
participant in this Plan. Each participant shall receive promptly after the end
of each Purchase Period a report of his or her account setting forth the total
payroll deductions accumulated, the number of shares purchased, the per share
price thereof and the remaining cash balance, if any, carried forward to the
next Purchase Period or Offering Period, as the case may be.
17. Notice of Disposition. Each participant shall notify the Company if
the participant disposes of any of the shares purchased in any Offering Period
pursuant to this Plan if such disposition occurs within two (2) years from the
Offering Date or within one (1) year from the Purchase Date on which such shares
were purchased (the "Notice Period"). Unless such participant is disposing of
any of such shares during the Notice Period, such participant shall keep the
certificates representing such shares in his or her name (and not in the name of
a nominee) during the Notice Period. The Company may, at any time during the
Notice Period, place a legend or legends on any certificate representing shares
acquired pursuant to this Plan requesting the Company's transfer agent to notify
the Company of any transfer of the shares. The obligation of the participant to
provide such notice shall continue notwithstanding the placement of any such
legend on the certificates.
18. No Rights to Continued Employment. Neither this Plan nor the grant
of any option hereunder shall confer any right on any employee to remain in the
employ of the Company or any Participating Subsidiary, or restrict the right of
the Company or any Participating Subsidiary to terminate such employee's
employment.
19. Equal Rights And Privileges. All eligible employees shall have
equal rights and privileges with respect to this Plan so that this Plan
qualifies as an "employee stock purchase plan" within the meaning of Section 423
or any successor provision of the Code and the related regulations. Any
provision of this Plan which is inconsistent with Section 423 or any successor
provision of the Code shall, without further act or amendment by the Company or
the Board, be reformed to comply with the requirements of Section 423. This
Section 19 shall take precedence over all other provisions in this Plan.
20. Notices. All notices or other communications by a participant to
the Company under or in connection with this Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof.
21. Term; Stockholder Approval. After this Plan is adopted by the
Board, this Plan will become effective on the date that is the First Offering
Date (as defined above); provided, however, that if the First Offering Date does
not occur on or before December 31, 1997, this Plan will terminate having never
become effective. This Plan shall be approved by the stockholders of the
Company, in any manner permitted by applicable corporate law,
within twelve (12) months before or after the date this Plan is adopted by the
Board. No purchase of shares pursuant to this Plan shall occur prior to such
stockholder approval. This Plan shall continue until the earlier to occur of (a)
termination of this Plan by the Board (which termination may be effected by the
Board at any time), (b) issuance of all of the shares of Common Stock reserved
for issuance under this Plan, or (c) ten (10) years from the adoption of this
Plan by the Board.
22. Designation of Beneficiary.
(a) A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under this Plan in the event of such participant's death subsequent to the end
of an Purchase Period but prior to delivery to him of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under this Plan in the event
of such participant's death prior to a Purchase Date.
(b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under this
Plan who is living at the time of such participant's death, the Company shall
deliver such shares or cash to the executor or administrator of the estate of
the participant, or if no such executor or administrator has been appointed (to
the knowledge of the Company), the Company, in its discretion, may deliver such
shares or cash to the spouse or to any one or more dependents or relatives of
the participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.
23. Conditions Upon Issuance of Shares; Limitation on Sale of Shares.
Shares shall not be issued with respect to an option unless the exercise of such
option and the issuance and delivery of such shares pursuant thereto shall
comply with all applicable provisions of law, domestic or foreign, including,
without limitation, the Securities Act, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange or automated quotation system upon which the shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.
24. Applicable Law. The Plan shall be governed by the substantive laws
(excluding the conflict of laws rules) of the State of Connecticut.
25. Amendment or Termination of this Plan. The Board may at any time
amend, terminate or extend the term of this Plan, except that any such
termination cannot affect options previously granted under this Plan, nor may
any amendment make any change in an option previously granted which would
adversely affect the right of any participant, nor may any amendment be made
without approval of the stockholders of the Company obtained in accordance with
Section 21 hereof within twelve (12) months of the adoption of such amendment if
such amendment would:
(a) increase the number of shares that may be issued under this
Plan; or
(b) change the designation of the employees (or class of
employees) eligible for participation in this Plan.
