                          EMPLOYEE STOCK PURCHASE PLAN
                          (As Amended on May 30, 2001)

         This EMPLOYEE STOCK PURCHASE PLAN (the "Plan") is hereby established by
NEWPORT CORPORATION (the "Company") effective January 1, 1995 (the "Effective

         1.1 Purpose. The Company has determined that it is in its best

interests to provide an incentive to attract and retain employees and to
increase employee morale by providing a program through which employees may
acquire a proprietary interest in the Company through the purchase of shares of
the common stock of the Company ("Company Stock"). The Plan is hereby
established by the Company to permit employees to subscribe for and purchase
directly from the Company shares of the Company Stock at a discount from the
market price, and to pay the purchase price in installments by payroll
deductions. The Plan is intended to qualify as an "employee stock purchase plan"
under Section 423 of the Internal Revenue Code of 1986, as amended from time to
time (the "Code"). The provisions of the Plan are to be construed in a manner
consistent with the requirements of Section 423 of the Code. The Plan is not
intended to be an employee benefit plan under the Employee Retirement Income
Security Act of 1974, and therefore is not required to comply with that Act.

                                       3

the value of one share of Company Stock, determined as follows:

         (a)   If the Company Stock is then listed or admitted to trading on the
Nasdaq National Market System or a stock exchange which reports closing sale
prices, the Fair Market Value shall be the closing sale price on the date of
valuation on the Nasdaq National Market System or principal stock exchange on
which the Company Stock is then listed or admitted to trading, or, if no closing
sale price is quoted or no sale takes place on such day, then the Fair Market
Value shall be the closing sale price of the Company Stock on the Nasdaq
National Market System or such exchange on the next preceding day on which a
sale occurred.

         (b)   If the Company Stock is not then listed or admitted to trading on
the Nasdaq National Market System or a stock exchange which reports closing sale
prices, the Fair Market Value shall be the average of the closing bid and asked
prices of the Company Stock in the over-the-counter market on the date of
valuation.

         (c)   If neither (a) nor (b) is applicable as of the date of valuation,
then the Fair Market Value shall be determined by the Administrator in good
faith using any reasonable method of evaluation, which determination shall be
conclusive and binding on all interested parties.

                                PURCHASE OF STOCK
                                -----------------

         7.1   Purchase of Company Stock. Absent an election by the Participant
               -------------------------
to terminate and have his or her Account returned, on each Purchase Date, the
Plan shall purchase on behalf of each Participant the maximum number of whole
shares of Company Stock at the purchase price determined under Section 6.2 above
as can be purchased with the amounts held in each Participant's Account. The
Plan shall not be required to purchase any fractional shares of Company Stock.
In the event that there are amounts held in a Participant's Account that are not
used to purchase Company Stock, all such amounts shall be held in the
Participant's Account and carried forward to the next Offering Period.

         7.2   Delivery of Company Stock.
               -------------------------

         (a)   Company Stock acquired under the Plan may either be issued
directly to Participants or may be issued to a contract administrator
("Administrator") engaged by the Company to administer the Plan under Article
IX. If the Company Stock is issued in the name of

                                       4

<PAGE>

the Administrator, all Company Stock so issued ("Plan Held Stock") shall be held
in the name of the Administrator for the benefit of the Plan. The Administrator
shall maintain accounts for the benefit of the Participants which shall reflect
each Participant's interest in the Plan Held Stock. Such accounts shall reflect
the number of shares of Company Stock that are being held by the Administrator
for the benefit of each Participant.

         (b)   Any Participant may elect to have the Company Stock purchased
under the Plan from his or her Account be issued directly to the Participant.
Any election under this paragraph shall be on the forms provided by the Company
and shall be issued in accordance with paragraph (c) below.

         (c)   In the event that Company Stock under the Plan is issued directly
to a Participant, the Company will deliver to each Participant a stock
certificate or certificates issued in his name for the number of shares of
Company Stock purchased as soon as practicable after the Purchase Date. The time
of issuance and delivery of shares may be postponed for such period as may be
necessary to comply with the registration requirements under the Securities Act
of 1933, as amended, the listing requirements of any securities exchange on
which the Company Stock may then be listed, or the requirements under other laws
or regulations applicable to the issuance or sale of such shares.

                                   ----------

         8.1   In Service Withdrawals. At any time prior to the Purchase Date of
               ----------------------
an Offering Period, any Participant may withdraw the amounts held in his Account
by executing and delivering to the Human Resources Department for the Company
written notice of withdrawal on the form provided by the Company. In such a
case, the entire balance of the Participant's Account shall be paid to the
Participant, without interest, as soon as is practicable. Upon such
notification, that Participant shall cease to participate in the Plan for the
remainder of the Offering Period in which the notice is given. Any Employee who
has withdrawn under this Section shall be excluded from participation in the
Plan for the remainder of the Offering Period and the next succeeding Offering
Period, but may then be reinstated as a Participant for a subsequent Offering
Period by executing and delivering a new Subscription Agreement to the
Committee.

         8.2   Termination of Employment.
               -------------------------

         (a)   In the event that a Participant's employment with the Company
terminates for any reason, the Participant shall cease to participate in the
Plan on the date of termination. As soon as is practical following the date of
termination, the entire balance of the Participant's Account shall be paid to
the Participant or his beneficiary, without interest.

         (b)   A Participant may file a written designation of a beneficiary who
is to receive any shares of Company Stock purchased under the Plan or any cash
from the Participant's Account in the event of his or her death subsequent to a
Purchase Date, but prior to delivery of such shares and cash. In addition, a
Participant may file a written designation of a beneficiary who is to

                                       5

<PAGE>

receive any cash from the Participant's Account under the Plan in the event of
his death prior to a Purchase Date under paragraph (a) above.

          (c)  Any beneficiary designation under paragraph (b) above may be
changed by the Participant at any time by written notice. In the event of the
death of a Participant, the Committee may rely upon the most recent beneficiary
designation it has on file as being the appropriate beneficiary. In the event of
the death of a Participant and no valid beneficiary designation exists or the
beneficiary has predeceased the Participant, the Committee shall deliver any
cash or shares of Company Stock 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 Committee, the Committee, in its sole discretion, may
deliver such shares of Company Stock or cash to the spouse or any one or more
dependents or relatives of the Participant, or if no spouse, dependent or
relative is known to the Committee, then to such other person as the Committee
may designate.

               (iii) To establish rules and procedures from time to time for the

exercise of authority conferred upon it by this Plan shall be conclusive and
binding upon a Participant and his beneficiaries. All discretionary powers

the extent permitted by law, the Company shall indemnify each member of the
Board or Committee, and any other Employee of the Company with duties under the
Plan who was or is a party, or is threatened to be made a party, to any
threatened, pending or completed proceeding, whether civil, criminal,
administrative, or investigative, by reason of the person's conduct in the

Company Stock to be sold to Participants under the Plan will be either purchased

securities laws or issued by the Company. If the total number of shares of
Company Stock that would otherwise be issuable or purchasable pursuant to rights
granted pursuant to Section 6.1 of the Plan at the Purchase Date exceeds the
number of shares then available under the Plan, the Company shall make a pro
rata allocation of the shares remaining available in as uniform and equitable a
manner as is practicable. In such event, the Company shall give written notice
of such reduction of the number of shares to each participant affected thereby
and any unused payroll deductions shall be returned to such participant if
necessary.

               ----------------------------------------
action by the shareholders of the Company, the number of shares of Company Stock
covered by each right under the Plan which has not yet been exercised and the
number of shares of Company Stock which have been authorized for issuance under
the Plan but have not yet been placed under rights or which have been returned
to the Plan upon the cancellation of a right, as well as the Purchase Price per
share of Company Stock covered by each right under the Plan which has not yet
been exercised, shall be proportionately adjusted for any increase or decrease
in the number of issued shares of Company Stock resulting from a stock split,
stock dividend, spin-off, reorganization, recapitalization, merger,
consolidation, exchange of shares or the like. Such adjustment shall be made by
the Board of Directors for the Company, whose determination in that respect
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 Company
Stock subject to any right granted hereunder.

          10.5 Merger of Company. In the event that the Company at any time
               -----------------
proposes to merge into, consolidate with or to enter into any other
reorganization pursuant to which the Company is not the surviving entity
(including the sale of substantially all of its assets or a "reverse" merger in
which the Company is the surviving entity), the Plan shall terminate, unless
provision is made in writing in connection with such transaction for the
continuance of the Plan and for the assumption of rights theretofore granted, or
the substitution for such rights of new rights covering the shares of a
successor corporation, with appropriate adjustments as to number and kind of
shares and prices, in which event the Plan and the rights theretofore granted or
the new rights substituted therefore, shall continue in the manner and under the
terms so provided. If such provision is not made in such transaction for the
continuance of the Plan and the assumption of rights theretofore granted or the
substitution for such rights of new rights covering the shares of a successor
corporation, then the Board of Directors or its committee shall cause written
notice of the proposed transaction to be given to the persons holding rights not
less than 10 days prior to the anticipated effective date of the proposed
transaction, and, concurrent with the effective date of the proposed
transaction, such rights shall be exercised automatically in accordance with
Section 7.1 as if such effective date were a Purchase Date of the applicable
Offering Period unless a Participant withdraws from the Plan as provided in
Section 8.1.

foreseen, the Company reserves the right to amend, modify, or terminate the Plan
at any time. Upon termination of the Plan, all benefits shall become payable
immediately. Notwithstanding the foregoing, no such amendment or termination
shall affect rights previously granted, nor may an amendment make any change in

Participant. In addition, no amendment may be made without prior approval of the
shareholders of the Company if such amendment would:

               issued under the Plan;

          (b)  Materially modify the requirements as to eligibility for

               under the Plan.

          11.2 Shareholder Approval. Continuance of the Plan and the
               --------------------
effectiveness of any right granted hereunder shall be subject to approval by the
shareholders of the Company, within twelve months before or after the date the

assignment, transfer, pledge or other disposition shall be without effect,
except that the Company may treat such act as an election to withdraw funds in
accordance with Article VIII.
