--------------------------------------------------------------------------------



                                PROXY STATEMENT

The enclosed Proxy is solicited on behalf of Neogen Corporation (the "Company")
for use at the Annual Meeting of Shareholders to be held October 9, 2002, at
10:00 a.m., local time, or at any adjournment thereof, for the purposes set
forth herein and in the accompanying Notice of Annual Meeting of Shareholders.
The Annual Meeting will be held at the University Club of Michigan State
University, 3435 Forest Road, Lansing, MI 48909. The Company's telephone number
is (517) 372-9200.

These proxy solicitation materials were mailed on or about September 4, 2002,
together with the Company's 2002 Annual Report to Shareholders, to all
shareholders entitled to vote at the meeting.

INFORMATION CONCERNING SOLICITATION AND VOTING

Revocability of Proxies

Any proxy given pursuant to this solicitation may be revoked by the person
giving it any time before its use by delivering to the Company, before the
meeting, a written notice of revocation or a duly executed proxy bearing a
later date or by attending the meeting and voting in person.

Voting and Solicitation

Every shareholder voting at the annual meeting has one vote for each share on
all matters. The Company's By-Laws do not provide for cumulative voting in the
election of directors. Shares represented by valid, executed and dated proxies
in the enclosed form will be voted if received in time for the meeting in
accordance with the instructions thereon. Unless your proxy is otherwise
marked, it will be voted FOR management's nominees for the board of directors
and FOR the approval of the Neogen Corporation 2002 Employee Stock Purchase
Plan.

A simple majority of the shares issued and outstanding as of August 12, 2002
(the "Record Date") must be present or represented at the Annual Meeting to
constitute a quorum. For election of directors, the three individuals receiving
the most votes will be elected for the term indicated. Approval of the Neogen
Corporation 2002 Employee Stock Purchase Plan and of any other item of business
to be voted upon at the Annual Meeting will require the affirmative vote of a
majority of the votes cast by the holders of common shares at the meeting and
entitled to vote. Abstentions, withheld votes and broker nonvotes will not be
deemed votes cast in determining approval of any proposal, but will be counted
in determining the number of common shares present or represented by proxy in
determining whether a quorum is present.

The cost of soliciting proxies will be borne by the Company. The Company has
retained the services of American Stock Transfer & Trust to aid in the
solicitation of proxies. The Company estimates that the cost of soliciting
proxies will be less than $2,000 including out-of-pocket expenses. The Company
may reimburse brokerage firms and other persons representing beneficial owners
of shares for their expenses in forwarding solicitation material to such
beneficial owners. Proxies may also be solicited by certain of the Company's
directors, officers, and regular employees, without additional compensation,
personally by telephone, e-mail, facsimile or letter.

                II. PROPOSAL TO APPROVE THE NEOGEN CORPORATION
                       2002 EMPLOYEE STOCK PURCHASE PLAN

Management is seeking shareholder approval of the Neogen Corporation Employee
Stock Purchase Plan. If shareholders approve the plan at the meeting, the
initial purchases under the plan by eligible employees who have enrolled in the
plan will occur on June 1, 2003. Under the plan, the Company will grant
eligible employees the right to purchase Neogen Corporation common shares
through payroll deductions at a price equal to 95 percent of the lesser of the
fair market value of Neogen Corporation common shares on the first or last day
of the offering period. If the plan is approved by shareholders, the first
offering period will begin on December 1, 2002. After that, there will be
consecutive six-month offering periods until July 25, 2012 or until the plan is
terminated by the Board, if earlier. Rights to buy common shares will not be
granted or exercised under the plan if shareholder approval of the plan is not
obtained before December 31, 2002.

The purpose of the plan is to encourage employee stock ownership by offering
employees rights to purchase Neogen Corporation common shares at discounted
prices and without payment of brokerage costs. Management believes that the
plan offers a convenient means for Neogen Corporation employees who might not
otherwise own Neogen Corporation common shares to purchase and hold such an
investment. Management also believes that the discounted sale feature of the
plan offers a meaningful incentive to participate, and that employees'
continuing economic interests as shareholders in Company performance and
success should further enhance entrepreneurial spirit and contribute to the
Company's potential for growth and profitability. The Board of Directors
adopted the plan on July 25, 2002, subject to shareholder approval. The Board
of Directors recommends a vote FOR approval of the proposed plan, and your
proxy will be so voted unless you specify otherwise.

As of the Record Date, the closing sale price of Neogen Corporation common
shares was $11.89. As of the Record Date approximately 240 employees were
eligible to participate in the plan. The plan is intended to be an "employee
stock purchase plan" as defined in Section 423 of the Internal Revenue Code.

Vote Required

Management is seeking shareholder approval to qualify the plan as an "employee
stock purchase plan" under Section 423 of the Internal Revenue Code and the
related regulations. To be considered approved under Section 423, the plan must
be approved by a majority of the votes cast by the holders of common shares
entitled to vote on the proposal. Abstentions, withheld votes and broker
non-votes will not be deemed votes cast in determining approval of this
proposal and will not have the effect of a vote for or against the proposal.
They will be counted in determining the number of common shares present or
represented by proxy in determining whether a quorum is present at the Annual
Meeting.

Description of the Plan

Shares Subject to the Plan

   The plan covers 100,000 common shares. If any purchase right under the plan
expires or terminates without having been exercised in full, the underlying
common shares that were not purchased are again available under the plan,
unless the plan has been terminated. To prevent dilution or enlargement of the
rights of participants under the plan, appropriate adjustments will be made if
any change is made to outstanding common shares by reason of any stock
dividend, stock split, combination of shares, exchange of shares, change in
corporate structure, merger, reorganization, recapitalization, dividend in
property other than cash, liquidating dividend or other change in common shares
where no consideration is received. Shares are automatically acquired by
participants as of the last day of the applicable purchase period, unless the
participant's employment has terminated or there are insufficient shares
available under the plan.

                                      6



Plan Participants

All full-time employees of Neogen Corporation and its designated subsidiaries,
including officers and directors who are employees, are eligible to participate
in the plan, unless after the grant of purchase rights under the plan, the
employee would own, directly or by attribution, stock, purchase rights or
options to purchase stock representing three percent or more of the total
combined voting power or value of all outstanding classes of stock.

Participation in the plan is voluntary and is dependent upon each eligible
employee's election to participate and his or her determination as to the
desired level of participation, subject to the plan's limits. Eligible
employees become participants in the plan by authorizing payroll deductions for
that purpose no later than ten calendar days after the beginning of an offering
period. Participation is effective for payrolls after the beginning of the
applicable offering period. Newly-hired or re-hired employees may become
participants in the plan by authorizing payroll deductions within 180 days
after their date of hire. Participants cannot be granted purchase rights which
exceed $25,000, based on the fair market value of the stock (at the time of
grant).

Payroll Deductions

Participants may purchase shares only by means of payroll deduction of up to 10
percent of the participant's total compensation during the offering period.
Total compensation means, in general, wages, salaries and other amounts
received from Neogen Corporation for personal services rendered to the Company
as an employee, including commissions, bonuses and salary or bonus reduction
contributions to plans under Section 401(k) or Section 125 of the Internal
Revenue Code. After initial enrollment in the plan, payroll deductions will
continue from offering period to offering period and cannot be changed or
withdrawn unless the participant elects a different contribution percentage,
elects to terminate his or her payroll deductions or becomes ineligible to
participate in the plan. The amounts deducted will be credited to the
participant's account under the plan, but no separate account to hold such
amounts will be established and no interest on the deducted amounts will be
paid. Deducted amounts may be commingled with the Company's general assets and
may be used for general corporate purposes. The amounts will, therefore, be
subject to the claims of creditors and any applicable liens on assets.

Purchase Rights and Purchases

On the first day of each offering period, the Company is deemed to grant each
participant a non-transferable option to purchase, on the last day of the
offering period, as many whole common shares as the participant can purchase
with the payroll deductions credited to his or her account during that period.
The option to purchase will be exercised automatically on the last day of the
offering period. Fractional shares will not be issued under the plan, and any
amount remaining in the participant's account after such exercise will be held
for the purchase of common shares in the next offering period.

If insufficient shares remain available in any offering period under the plan,
the shares available will be allocated pro rata among the participants in that
offering period in proportion to the relative amounts in their accounts,
subject to rounding to allocate only whole common shares. Any amounts not
applied to the purchase of common shares will be refunded to the participants
after the end of the offering period without interest.

Withdrawal

A participant may withdraw from the plan (i.e., terminate his or her payroll
deductions) by providing notice to the Plan Administrator at any time prior to
10 business days before the end of the current offering period. The participant
may elect to stop his or her future payroll deductions under the plan and use
the amounts already credited to the participant's account under the plan to
purchase whole common shares at the end of the offering period or may elect to
continue his or her participation in the plan through the end of the current
offering period but terminate his or her participation for subsequent offering
periods. A participant who withdraws from the plan

                                      7



will not be eligible to rejoin the plan for the offering period underway at the
time of withdrawal, and will have to re-enroll in the plan should such
individual wish to resume participation in a subsequent offering period.
Withdrawal does not entitle a participant to a refund of sums previously
collected from the participant during the offering period (except in connection
with the termination of employment).

Termination of Employment

If a participant ceases to be an employee for any reason other than death
during an offering period, his or her outstanding option to purchase common
shares under the plan will immediately terminate, his or her payroll deductions
will immediately cease, and all sums previously collected from the participant
during the offering period under the terminated option will be refunded. If a
participant's employment terminates as a result of his or her death,
participation in the plan by the participant will terminate for future offering
periods, further payroll deductions will cease, amounts credited to the
participant's account prior to his or her death will be used to purchase whole
common shares at the end of the offering period and any amounts remaining after
such purchase will be distributed to the participant's estate.

Administration

The plan is administered by the Board of Directors of Neogen Corporation and/or
any committee (such as the Compensation Committee) of at least two directors to
which our Board of Directors has delegated any of its duties under the plan.
The Board determines the commencement and termination date of the offering of
common shares under the plan and is authorized, among other things, to
interpret the terms of the plan, establish rules for the administration of the
plan and correct or reconcile any defect or inconsistency in the plan.

The Board or the committee may delegate all or part of its authority to
administer the plan to the Plan Administrator, who may further delegate the
routine operations of the plan. Except for fees to withdraw shares in the form
of certificates and to sell shares through a broker, the costs and expenses
incurred in the administration of the plan and the maintenance of accounts with
the custodian of the plan will be paid by the Company.

Sale or Distribution of Common Shares Acquired Under the Plan

Participants may elect to have the plan custodian or a broker-dealer selected
by the Company hold the common shares they acquire under the plan and may sell
those shares as of the first business day of any fiscal quarter. Brokerage
commissions in connection with such a sale will be borne by the participant.
Alternatively, participants and former participants may, at their expense,
withdraw the shares held for them and have certificates issued in their name as
of the first business day of any fiscal quarter.

Non-Assignability

Neither payroll deductions credited to a participant's account nor any rights
to acquire common shares under the plan may be assigned, transferred, pledged
or otherwise disposed of by participants other than by will or the laws of
descent and distribution and rights to acquire common shares may be exercised
only by a participant during the lifetime of a participant. The plan custodian
will maintain accounts only in the names of the participants.

Amendment

The Board may terminate or amend the plan and any rights to acquire common
shares under the plan at any time; provided, however:

    .  such termination or amendment may not impair any rights and obligations
       under rights to acquire common shares previously granted under the plan
       without the consent of the affected participants, and

    .  any amendment that increases the number of shares reserved for issuance
       under the plan (except for allowable adjustments in the event of changes
       to outstanding common shares or for changes the plan authorizes the
       Board or the Plan Administrator to make) or changes the eligibility
       requirements for

                                      8



       participation in the plan, is subject to shareholder approval to the
       extent required by the Internal Revenue Code.

Change in Control of the Company

If the Company is acquired or are otherwise involved in a change in control
transaction of the kind described in the plan, the Board may:

    .  cancel each outstanding right to acquire common shares under the plan
       and refund all sums previously collected from participants under the
       canceled rights, or

    .  cause each participant to have his or her outstanding rights to acquire
       common shares under the plan exercised immediately before that
       transaction and thereby have the balance of his or her account applied
       to the purchase of whole common shares at the purchase price in effect
       for the offering period, which would be treated as ending on the
       effective date of such transaction.

If the Company merges with another entity and survives the merger, each
participant is entitled to receive, for each share purchased upon exercise of
rights to acquire common shares under the plan, the securities or property that
a holder of common shares was entitled to receive upon the merger.

United States Federal Income Tax Consequences

The following is a general summary of the material United States federal income
tax consequences to the Company and to participants in the plan based on the
Internal Revenue Code as currently in effect. This summary is necessarily
general in nature and does not purport to be complete.

The plan is intended to be an "employee stock purchase plan" as defined in
Section 423 of the Internal Revenue Code. That section provides that a
participant in the plan will generally realize no taxable income as a result of
the grant or exercise of rights to acquire common shares under the plan.
Amounts deducted from a participant's compensation to purchase shares under the
plan are taxable income to participants in the year in which the amounts would
otherwise have been received.

If the shares acquired under the plan are sold by the participant more than two
years after the grant of the applicable right (i.e., the beginning of the
applicable offering period), the participant will recognize as ordinary
compensation income an amount equal to the lesser of (1) the amount by which
the fair market value of the shares when purchased exceeds the purchase price
(i.e., the discount below fair market value), or (2) the amount, if any, by
which the fair market value of the shares at the time of the sale exceeds the
purchase price. The participant's tax basis in the shares purchased will
increase by the amount recognized as ordinary compensation income and any
further gain recognized on the sale will be treated as capital gain. In
general, the Company will not be entitled to a deduction for federal income tax
purposes with respect to such sale.

However, if the shares acquired under the plan are sold by the participant
within two years after the grant of the applicable right, the participant will
recognize ordinary compensation income in the year of such sale, the amount of
which will generally be the excess of the fair market value of the shares on
the date the shares were purchased (i.e., the end of the applicable offering
period) over the purchase price for those shares. The participant's tax basis
will increase by the amount recognized as compensation and any further gain or
loss realized upon the sale will be capital gain or loss. In general, the
Company will be entitled to a deduction for federal income tax purposes at the
time of such a sale in an amount equal to the ordinary compensation income
recognized by the participant. However, if the participant is one of the
Company's five most highly compensated employees in the year of sale, no
deduction will be available to the extent the participant's total ordinary
compensation income during that year exceeds $1 million.

Compensation Committee Report on Executive Compensation

   General. The Compensation Committee's overall compensation policy applicable
to the Company's executive officers is to provide a compensation program that
is intended to attract and retain qualified executives for the Company and to
provide them with incentives to achieve Company goals and increase shareholder
value. The Compensation Committee implements this policy through establishing
salaries and bonuses. The Compensation Committee's current policy is not to
provide significant pension or other retirement benefits for the Company's
employees.

   Salaries. The Compensation Committee's policy is to provide salaries that
are generally similar to those of similar executive officers in similar
companies. The Compensation Committee determines comparable salaries through
discussions with candidates for such positions, Company research and
independent surveys concerning the salaries paid by similar companies.

   Performance Bonuses. The payment of bonuses to executive officers is
directly related to their achievement of corporate and individual performance
goals established at the beginning of the year. The amount of the bonus paid,
if any, varies among the executive officers depending on their success in
achieving individual performance goals and on their contribution to the
achievement of corporate performance goals.

   Stock Options. Stock options are awarded by the Stock Option Committee of
the Board of Directors. The Stock Option Committee's policy is to award stock
options to the Company's officers in amounts reflecting the participant's
position and ability to influence the Company's overall performance. Options
are intended to provide participants with an increased incentive to make
contributions to the long-term performance of growth of the Company, to join
the interests of participants with the interests of shareholders of the Company
and to attract and retain qualified employees. The Stock Option Committee's
policy has been to grant options with terms of five to ten years to provide a
long-term incentive and to fix the exercise price of the options at the fair
market value of the underlying shares on the date of grant. As a result, such
options will only have value if the price of the underlying shares increases.

   Fiscal 2002 Compensation Decisions Regarding James Herbert. The compensation
of James L. Herbert, President and Chief Executive Officer, is recommended by
the Compensation Committee to the Board of Directors based on the Committee's
knowledge of the level necessary to enable the Company to remain competitive
and retain top management.

In addition, Mr. Herbert's compensation is based on the Committee's subjective
assessment of his progress toward achieving Company goals and objectives
pertaining to the development and marketing of products dedicated to food and
animal safety. Particular consideration is given to progress toward enhancing
long-term shareholder value that includes overall growth in sales and operating
and net income for the Company's most recent fiscal year.

Incentive compensation payments to Mr. Herbert are made partially in the form
of cash intended to reward Mr. Herbert for achievement of individual and
corporate objectives, partially in the form of stock options, intended to
provide Mr. Herbert with increased incentive to focus on long-term performance
growth of the Company that will enhance shareholder value, and partially in the
form of contributions to an annuity owned by the Company and payable to Mr.
Herbert or his estate upon death, retirement or termination of employment.

Mr. Herbert did not participate in the approval of his own compensation, but
did participate in discussion of the Company's performance for fiscal 2002 and
the determination of bonuses for other executive officers of the Company.

   The purpose of the Neogen Corporation 2002 Employee Stock Purchase Plan is
to encourage employee stock ownership by offering employees of Neogen
Corporation and its subsidiaries Purchase Rights (as such term is defined in

of brokerage costs. By means of this Plan, the Company seeks to retain the
services of its employees, to secure and retain the services of new employees,
and to provide incentives for such persons to exert maximum efforts for the
success of the Company. The Plan is intended to be an "employee stock purchase
plan" as defined in Section 423 of the Code. The provisions of the Plan shall,
accordingly, be construed so as to extend and limit the participation in a
manner consistent with the requirements of Section 423 of the Code.

5.  Securities Subject to the Plan and Offering Periods.

   (a) The Plan covers an aggregate of 100,000 Common Shares (subject to
adjustment as provided in Section 15), which may be authorized but unissued
shares or reacquired shares, bought on the open market or otherwise. If any
Purchase Right that shall have been granted under the Plan shall expire or
terminate for any reason without having been exercised in full, the unpurchased
underlying Common Shares shall again become available for purposes of the Plan,
unless the Plan shall have been terminated.

   (b) The first Offering Period (an "Offering Period") under the Plan will
begin on December 1, 2002 and end on May 31, 2003 . Thereafter, for so long as
the Plan remains in effect, there will be semi-annual Offering Periods with the

               Semi-Annual Offering
               Periods
                 Beginning Date                 Ending Date

                   December 1                       May 31

6.  Payroll Deductions.

   (a) In order to purchase Common Shares, an employee must indicate on the
Participation Form the contribution amount he or she wishes to authorize the
Company to deduct out of the employee's Total Compensation. Subject to the
limitation specified by Section 423(b) of the Code, the authorized contribution
amount must be an integral percentage amount (i.e., a whole number percentage)
ranging from 1% to 10% of such Participant's Total Compensation during the
Offering Period. The Participation Form will include authorization for the
Company to make payroll deductions from the Participant's Total Compensation.

   (b) To comply with the federal tax laws, a Participant may not be granted
Purchase Rights under the Plan or any other Code Section 423 employee stock
purchase plan of the Company, or of any parent or subsidiary corporation (as
those terms are defined for purposes of Section 423(b) of the Code) of the
Company, with respect to more than $25,000.00 worth of Common Shares for any
calendar year such Purchase Rights to purchase Common Shares are outstanding
pursuant to the terms of the Plan. The $25,000.00 limit is determined according
to the Fair Market Value of the Common Shares on the first day (grant date) of
the Offering Period. Participants will be notified if these limitations become
applicable to them.

   (c) The amounts deducted shall be credited to the Participant's account
under the Plan, but no actual separate account will be established by the
Company to hold such amounts. There shall be no interest paid on the balance
outstanding in a Participant's account. The deducted amounts may be commingled
with the general assets of the Company and may be used for its general
corporate purposes.

   (d) Payroll deductions begin on the first payday of each Offering Period,
and end on the last payday of each Offering Period. Eligible employees may
participate in the Plan and purchase shares only by means of payroll
deductions. A Participant may not make any separate cash payment into his or
her account.

   (e) So long as a Participant remains an employee of the Company eligible to
participate in the Plan, payroll deductions will continue in effect from
Offering Period to Offering Period unless the Participant:

      (i) on or before the end of the current Offering Period, elects a
   different contribution percentage by providing a new Participation Form to
   the Plan Administrator; such change in contribution percentage will become
   effective by the beginning of the next Offering Period following the Plan
   Administrator's receipt of the Participant's new Participation Form; or

      (ii) withdraws in accordance with Section 9.

                                      19



   (f) Unless a Participant elects a different contribution percentage as
permitted by Section 6(e)(i) or elects to withdraw prior to 10 business days
before the end of the current Offering Period as permitted under Section 9, the
Participant's payroll deductions will continue throughout the next Offering
Period and his or her Purchase Right to purchase Common Shares will be deemed
to be fully and automatically exercised on the last day of such Offering Period
with respect to payroll deductions made during that period.

7.  Purchase Price.

   (a) On the first day of each Offering Period, a Participant is deemed to
have been granted a Purchase Right to purchase on the last day of the Offering
Period as many whole Common Shares as such Participant will be able to purchase
with the payroll deductions credited to such Participant's account during that
Offering Period.

   (b) The price at which each Purchase Right to purchase Common Shares may be
exercised is the lower of the following (rounded up to the nearest whole cent
per Common Share):

      (i) 95% of the Fair Market Value of the Common Shares on the first day of
   an Offering Period, or if that day is not a Trading Day, then on the first
   preceding day that is a Trading Day; or

      (ii) 95% of the Fair Market Value of the Common Shares on the last
   Trading Day of such Offering Period.

   (c) The number of shares purchasable by each Participant per Offering Period
will be the number of whole Common Shares obtained by dividing the amount
collected from the Participant under the Plan for that Offering Period by the
purchase price in effect for that Offering Period.

8.  Exercise of Purchase Right.

   (a) Each outstanding Purchase Right will be exercised automatically on the
Exercise Date. The exercise of the Purchase Right is to be effected by applying
the amount credited to each Participant's account as of the Exercise Date to
the purchase on the Exercise Date of whole Common Shares at the purchase price
in effect for the Offering Period.

   (b) Fractional shares will not be issued under the Plan, and any amount
remaining in the Participant's account after such application (i.e., amounts
not sufficient to purchase a whole Common Share) will be held for the purchase
of Common Shares in the next Offering Period.

   (c) If the number of shares for which Purchase Rights are exercised exceeds
the number of shares remaining available in any Offering Period under the Plan,
the shares available for sale will be allocated by the Plan Administrator pro
rata among the Participants in such Offering Period in proportion to the
relative amounts in their accounts, subject to rounding to allocate only whole
Common Shares. Any amounts not thereby applied to the purchase of Common Shares
under the Plan will be refunded to the Participants after the end of the
Offering Period.

9.  Withdrawal and Termination of Purchase Rights.

   (a) A Participant may withdraw (i.e., terminate his or her payroll
deductions) by providing a notice of withdrawal to the Plan Administrator at
any time prior to 10 business days before the end of the current Offering
Period. Such notice shall be through a form, electronic authorization or other
withdrawal means (the "Withdrawal Form") provided by the Plan Administrator for
that purpose, and shall be effective by the tenth business day after it is
received by the Plan Administrator. The Withdrawal Form will permit a
Participant to make the following election:

      (i) The Participant may elect to stop the Participant's payroll
   deductions under the Plan and use all of the amounts credited to such
   Participant's account to purchase on the Exercise Date whole Common Shares
   at the purchase price in effect for the Offering Period. If this election is
   made, the Company shall distribute to such Participant after such Offering
   Period any such amounts which remain after such purchase on

                                      20



   account of being insufficient to purchase a whole Common Share at the
   applicable purchase price, unless the Participant has re-enrolled in the
   Plan, in which case such amounts shall be used to purchase Common Shares in
   the new Offering Period.

      (ii) The Participant may elect to continue his or her participation in
   the Plan through the end of the current Offering Period, and thus exercise
   such Participant's outstanding Purchase Rights on the following Exercise
   Date, but terminate his or her participation in the Plan for subsequent
   Offering Periods. Payroll deductions for such a Participant will continue
   until the end of the current Offering Period. If this election is made, the
   Company shall distribute to such Participant after such Offering Period any
   amounts which remain in the Participant's account after the purchase of
   Common Shares on the Exercise Date on account of being insufficient to
   purchase a whole Common Share at the applicable purchase price, unless the
   Participant has re-enrolled in the Plan, in which case such amounts shall be
   used to purchase Common Shares in the new Offering Period.

   (b) Any Participant who withdraws from the Plan pursuant to Section 9(a)
will not be eligible to rejoin the Plan for the Offering Period under way at
the time of withdrawal, and will have to re-enroll in the Plan by completing
and providing to the Plan Administrator a new Participation Form should such
individual wish to resume participation in a subsequent Offering Period.

   (c) If a Participant ceases to be an employee of the Company for any reason
during an Offering Period, his or her outstanding Purchase Right will
immediately terminate, his or her payroll deductions will immediately cease,
and all sums previously collected from such Participant during such Offering
Period under the terminated Purchase Right will be refunded; provided, however,
that if such termination is the result of the Participant's death, (1) the
outstanding Purchase Right shall terminate only for future Offering Periods,
(2) the Participant or the person or persons to whom the Participant's rights
under the Plan pass by will or by the laws of descent and distribution shall
continue as a Participant until the end of the Offering Period in which such
death occurs (except that no further payroll deductions shall be made under the
Plan), (3) the sums previously collected from such Participant during such
Offering Period under the Plan shall not be refunded during the Offering
Period, and (4) the Company shall use all of the amounts credited to such
Participant's account for the purchase on the Exercise Date of whole Common
Shares at the purchase price in effect for the Offering Period, and shall
distribute to such Participant after such Offering Period any such amounts
remaining after such purchase. For purposes of this Plan, a Participant
receiving short-term disability payments shall not be deemed to have ceased to
be an employee of the Company (and such payments shall be deemed to be part of
his or her Total Compensation) unless and until he or she becomes eligible to
receive long-term disability benefits.

10.  Rights as Shareholder.

   (a) A Participant is not a shareholder, and does not have any rights of a
shareholder, with respect to any Common Shares subject to Purchase Rights under
the Plan until the Participant exercises his or her Purchase Right and
certificates representing such shares have been issued, and then only with
respect to whole Common Shares issued to the Participant or credited to the
Participant's account. Thus, a Participant will not have a right to any
dividend or distribution on those shares made prior to the Exercise Date.

   (b) The Participant will be entitled to receive, as soon as practicable
after the Exercise Date, a stock certificate for the number of whole purchased
shares, if the Participant has so elected. The Participant may also elect to
have the Custodian hold his or her Common Shares acquired under the Plan. The
Custodian may impose upon, or pass through to, the Participant a reasonable fee
for withdrawal of Common Shares in the form of stock certificates. It is the
responsibility of each Participant to keep his or her address current with the
Company through the Plan Administrator and with the Custodian.

11.  Sale or Distribution of Common Shares Acquired Under the Plan.

   (a) Participants who elect to have the Custodian or a broker-dealer selected
by the Company hold the Common Shares they acquire under the Plan may sell
those shares only as of the first business day of each

                                      21



calendar quarter and only if the Participant submits a sales request form,
electronic authorization or other sales authorization means provided by the
Company to the Plan Administrator at least ten business days before the date on
which the Participant desires to have the Common Shares sold. Other
Participants who elect to receive a certificate for the Common Shares they
acquire under the Plan may sell those Common Shares at any time without
restriction under the Plan.

   (b) Participants and former Participants who elect to have the Custodian or
a broker-dealer selected by the Company hold the Common Shares they acquire
under the Plan may withdraw those shares and have certificates issued in the
Participant's name only as of the first business day of each calendar quarter
and only if the Participant submits a share withdrawal request form, electronic
authorization or other share withdrawal authorization means provided by the
Company to the Plan Administrator at least ten business days before the date on
which the Participant desires to have the Common Shares withdrawn.

   (c) A Participant shall immediately provide information to the Plan
Administrator if the Participant transfers any shares purchased through the
Plan within two years from the date of grant of the related Purchase Right.
Such transfers shall include transfers into street name and dispositions by
sale, gift or other manner. The Participant shall disclose the name of the
transferee, the manner of the transfer, the date of the transfer, the number of
shares involved and the transfer price. By executing the Participation Form,
each Participant obligates himself or herself to provide such information to
the Plan Administrator.

   (d) The Company is authorized to withhold from any payment to be made to a
Participant, including any payroll and other payments not related to the Plan,
amounts of withholding and other taxes due in connection with any transaction
under the Plan or any transaction involving Common Shares acquired under the
Plan, and a Participant's enrollment in the Plan will be deemed to constitute
his or her consent to such withholding.

12.  Plan Administration.

   (a) The Plan shall be administered by the Board.

   (b) The Board shall have the plenary power, subject to, and within the
limits of, the express provisions of the Plan:

      (i) to determine the commencement and termination date of the offering of
   Common Shares under the Plan;

      (ii) to interpret the terms of the Plan and the rights granted under it,
   establish, amend and revoke rules for the administration of the Plan and
   correct or reconcile any defect, omission or inconsistency in the Plan;

      (iii) to amend the Plan as provided in Section 16; and

      (iv) to exercise such powers and to perform such acts as the Board deems
   necessary or expedient to carry out the purposes of the Plan or to promote
   the best interests of the Company.

   (c) The Board may delegate all or part of its authority to administer the
Plan to the Plan Administrator, who may in turn delegate the day-to-day
operations of the Plan to the Custodian or any other person or entity the Plan
Administrator designates. The Custodian will establish and maintain, as agent
for the Participants, accounts for the purpose of holding Common Shares as may
be necessary or desirable for the administration of the Plan for those
Participants electing to have the Custodian hold the Common Shares they acquire
under the Plan.

   (d) The Board may waive or modify any requirement that a notice or election
be made, provided or filed under the Plan a specified period in advance in an
individual case or by adoption of a rule or regulation under the Plan, without
the necessity of an amendment to the Plan.

13.  Transferability.

   (a) Any account maintained by the Custodian for the benefit of a Participant
with respect to shares acquired pursuant to the Plan may only be in the name of
the Participant.

                                      22



   (b) Neither payroll deductions credited to a Participant's account nor any
Purchase Rights or other rights to acquire Common Shares under the Plan may be
assigned, transferred, pledged or otherwise disposed of by Participants other
than by will or the laws of descent and distribution and Purchase Rights may be
exercised only by a Participant during the lifetime of a Participant.

14.  Merger or Liquidation of the Company.

   If (1) Neogen Corporation dissolves or is liquidated, (2) Neogen Corporation
merges with another entity and the Company is not the surviving entity, (3)
more than 50% of the stock of Neogen Corporation is acquired by another entity,
(4) all or substantially all of the assets of Neogen Corporation are acquired
by another entity, or (5) any other similar transaction occurs, the Board may,
in its discretion, in connection with such transaction, cancel each outstanding
Purchase Right and refund all sums previously collected from Participants under
the canceled Purchase Rights, or cause each Participant with outstanding
Purchase Rights to have his or her outstanding Purchase Rights exercised
immediately prior to such transaction and thereby have the balance of his or
her account applied to the purchase of Common Shares at the purchase price in
effect for the Offering Period, which would be treated as ending with the
effective date of such transaction. In the event of a merger in which the
Company is the surviving entity, each Participant is entitled to receive, for
each share as to which such Participant's Purchase Rights are exercised, the
securities or property that a holder of one Common Share was entitled to
receive upon the merger.

15.  Adjustment.

   To prevent dilution or enlargement of the rights of Participants under the
Plan, appropriate adjustments shall be made in the event any change is made to
the Company's outstanding Common Shares (or other securities then subject to
the Plan or any Purchase Right) by reason of any stock dividend, stock split,
combination of shares, exchange of shares, change in corporate structure,
merger, reorganization, recapitalization, dividend in property other than cash,
liquidating dividend or other change in the Common Shares effected without the
Company's receipt of consideration. Adjustments shall be made to the maximum
number and class of securities issuable under the Plan and the number and class
of securities and price per share in effect under each outstanding Purchase
Right. Any such adjustments will be made by the Board, and its determination of
the appropriate adjustments shall be made in its sole discretion.

16.  Amendment and Termination.

   The Board may terminate or amend the Plan and any Purchase Rights at any
time and from time to time; provided, however, (1) such termination or
amendment may not impair any rights and obligations under Purchase Rights
previously granted under the Plan without the consent of each of the affected
Participants, and (2) any amendment that increases the number of shares
reserved for issuance upon exercise of Purchase Rights under the Plan (except
pursuant to Section 14 or 15 and any other changes authorized by the Plan to be
made by the Board or the Plan Administrator) or changes the eligibility
requirements for participation in the Plan, shall be subject to shareholder
approval to the extent required by the Code. The Board may, from time to time,
designate the parent corporations or subsidiary corporations (as such terms are
defined for purposes of Code Section 423(b)) of Neogen Corporation that may
participate in the Plan. The Plan expressly contemplates that the Board may
amend the Plan in any respect the Board deems necessary or advisable to provide
eligible employees with the benefits provided or to be provided under the
provisions of the Code and the regulations promulgated under the Code relating
to employee stock purchase plans and/or to bring the Plan and/or the Purchase
Rights into compliance with those provisions and regulations. If not sooner
terminated by the Board or terminated by expiration, the Plan shall terminate
at the time Purchase Rights have been exercised with respect to all Common
Shares reserved for acquisition under the Plan. Unless sooner terminated, the
Plan shall terminate ten years after its initial adoption by the Board. No
Purchase Rights may be granted under the Plan after it is terminated.

17.  Shareholder Approval.

   The Plan is subject to the approval of shareholders of Neogen Corporation at
the 2002 Annual Meeting of Shareholders. Purchase Rights will not be granted or
exercised under the Plan if shareholder approval of the Plan is not obtained
before November 30, 2002.

                                      23



18.  No Employment Rights.

   Participation in the Plan will not impose any obligations upon the Company
to continue the employment of a Participant for any specific period and will
not affect the right of the Company to terminate a Participant's employment at
any time, with or without cause.

19.  Costs.

   Except as set forth in Section 10(b), costs and expenses incurred in the
administration of the Plan and the maintenance of accounts with the Custodian
will be paid by the Company, to the extent provided in this Section 19. Any
brokerage fees and commissions for the purchase of Common Shares under the Plan
will be paid by the Company, but any brokerage fees and commissions for the
sale of Common Shares acquired under the Plan by a Participant will be borne by
such Participant.

20.  Reports.

   After the close of each Offering Period, each Participant in the Plan will
receive a report indicating the amount of the Participant's contributions to
the Plan during the Offering Period, the amount of the contributions applied to
the purchase of Common Shares for the Offering Period, and the purchase price
per share in effect for the Offering Period.

21.  Governing Law.

   The validity, construction and effect of the Plan and any rules and
regulations relating to the Plan will be determined in accordance with laws of
the State of Michigan, without giving effect to principles of conflict of laws,
and applicable federal law.

22.  Compliance With Legal and Other Requirements.

   The Plan, the granting and exercising of Purchase Rights under the Plan, and
the obligations of the Company, the Plan Administrator and the Custodian under
the Plan will be subject to all applicable federal and state laws, rules, and
regulations, and to such approvals by any regulatory or governmental agency as
may be required. The Company may, in its discretion, postpone the issuance or
delivery of Common Shares upon exercise of Purchase Rights until completion of
registration or qualification of such Common Shares or other required action
under any federal or state law, rule, or regulation, listing or other required
action with respect to any automated quotation system or stock exchange upon
which the Common Shares or other Company securities are designated or listed,
or compliance with any other contractual obligation of the Company, as the
Company may consider appropriate, and may require any Participant to make such
representations and furnish such information as it may consider appropriate in
connection with the issuance or delivery of Common Shares in compliance with
applicable laws, rules, and regulations, designation or listing requirements,
or other contractual obligations. If the Company is unable to obtain from any
such regulatory commission or agency the authority that counsel for the Company
deems necessary for the lawful issuance and sale of Common Shares under the
Plan, the Company shall be relieved from any liability for failure to issue and
sell Common Shares upon exercise of Purchase Rights unless and until such
authority is obtained.

23.  Indemnification.

   To the extent permitted, the Company shall indemnify and save harmless the
Board, Plan Administrator and Custodian members who are officers, directors,
shareholders or employees of the Company against any liabilities incurred by
them in the exercise and performance of their powers and duties under the Plan.

24.  Notices and Agreements.

   Any notices or agreements provided for in the Plan shall be given in
writing, in a form provided by the Company, and unless specifically provided
for in the Plan, shall be deemed effectively given upon receipt or, in the case
of notices and agreements delivered by the Company, three days after deposit in
the United States mail, postage prepaid.
