to have occurred at such time as (i) any “person” (as that term is used in
Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the “beneficial
owner” (as defined in Rule 13d-3 under the 1934 Act), directly or indirectly, of

still in office who were directors at the beginning of the period; (iii) the
consummation of any merger or consolidation as a result of which the Jacobs
Common Stock (as defined below) shall be changed, converted or exchanged (other

of the Company or any sale or other disposition of 50% or more of the assets or
earning power of the Company; or (iv) the consummation of any merger or
consolidation to which the Company is a party as a result of which the persons
who were shareholders of the Company immediately prior to the effective date of
the merger or consolidation shall have beneficial ownership of less than 50% of
the combined voting power for election of directors of the surviving corporation
following the effective date of such merger or consolidation; provided, however,
that no Change in Control shall be deemed to have occurred if, prior to such
time as a Change in Control would otherwise be deemed to have occurred, the
Board of Directors of the Company determines otherwise.”

another contract, including an employment agreement) the Company’s termination
of the Employee’s employment with the Company following the occurrence of any

  “12. Adjustment in the Number of Shares and in Option Price.

Except as provided in Paragraph 18, in the event there is any change in the
shares of Jacobs Common Stock through the declaration of stock dividends, or
stock splits or through recapitalization or merger or consolidation or
combination of shares or spin-offs or otherwise, the Committee or the Board of
Directors of the Company shall make such adjustment, if any, as it may deem
appropriate in the number of shares of Jacobs Common Stock available for
Incentive Awards as well as the number of shares of Jacobs Common Stock subject
to any outstanding Incentive Award and the option price, if any, thereof. Any
such adjustment may provide for the elimination of any fractional shares that
might otherwise become subject to any Incentive Award without payment
therefore.”

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

5. Paragraph 13 of the Plan is hereby deleted in its entirety and replaced with
the following:

“13. Awards of Restricted Stock and Restricted Stock Units.

(a) An Incentive Award in the form of shares of Restricted Stock or Restricted
Stock Units may be awarded under this Paragraph 13 as determined by the
Committee. Restricted Stock and Restricted Stock Units awarded under this Plan
shall not be sold, exchanged, transferred, pledged, hypothecated or otherwise
disposed of. The restrictions against disposition and the obligation to forfeit
and surrender shares to the Company are herein referred to as “Forfeiture
Restrictions”, and the shares that are then subject to the Forfeiture
Restrictions are referred to as “Restricted Stock.” Any certificates
representing Restricted Stock shall be appropriately legended to reflect the
Forfeiture Restrictions. Restricted Stock Units are Incentive Awards denominated
in units of Jacobs Common Stock under which the issuance of Jacobs Common Stock
is subject to such vesting conditions (including continued employment or
performance conditions) and other terms and conditions as the Committee deems
appropriate. Each Restricted Stock Unit shall be equal to one share of Jacobs
Common Stock and shall, subject to satisfaction of any vesting and/or other
terms and conditions, entitle an Employee to the issuance of one share of Jacobs
Common Stock in settlement of the Incentive Award.

(b) The number of shares of Jacobs Common Stock that may be issued under this
Plan pursuant to awards of Restricted Stock and/or Restricted Stock Units shall
be limited to 10% of the first 11,200,000 shares authorized for issuance as
Incentive Awards under this Plan, and 50% of any shares authorized for issuance
under this Plan in excess of 11,200,000. Any shares issued under this Plan
pursuant to awards of Restricted Stock and/or Restricted Stock Units that are
forfeited shall again be available for reissuance as Restricted Stock and/or
Restricted Stock Units.

(c) The Forfeiture Restrictions with respect to Restricted Stock issued under
this Paragraph 13 shall lapse and be of no further force and effect, and
Restricted Stock Units issued under this Paragraph 13 shall vest, in each case
upon the expiration of the period of time or the achievement of any performance
conditions, in each case as fixed by the Committee upon or prior to the grant of
the Incentive Award.

(d) In order to enforce the restrictions imposed upon shares of Restricted
Stock, the Committee may require the recipient to enter into an escrow agreement
providing that the certificates representing such shares of Restricted Stock
shall remain in the physical custody of an escrow holder until any or all of the
restrictions imposed pursuant to the Plan expire or shall have been removed.

(e) The Committee may make such provisions as it may deem appropriate for the
withholding or payment by the Employee of any withholding taxes which it
determines are required in connection the lapse of Forfeiture Restrictions
and/or vesting or settlement of Restricted Stock Units, and an Employee’s rights
in any Incentive Award are subject to satisfaction of such

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

conditions. If permitted by the Committee, the Employee may elect to satisfy all
or any portion of such taxes by instructing the Company to withhold shares of
Jacobs Common Stock as to which the restrictions have lapsed or that otherwise
would have been issued in settlement of the Incentive Award.

(f) If shares of Jacobs Common Stock are withheld to satisfy tax liabilities,
the value of such shares shall be computed using the Fair Market Value of the
Jacobs Common Stock on the date the tax liability arises.

(g) All of the foregoing restrictions, terms and other conditions regarding
awards of Restricted Stock and Restricted Stock Units shall be evidenced by a
written agreement between the Company and the Employee and containing such terms
and conditions, not inconsistent with the Plan, as the Committee shall approve.

(h) Schedule B, attached hereto, establishes the effects on outstanding awards
of Restricted Stock and Restricted Stock Units of an Employee’s termination of
employment, other changes of employment or employer status, death, Disability,
Retirement, or a Change in Control, and is hereby incorporated by reference. The
Committee may approve grants of Restricted Stock and Restricted Stock Units
containing terms and conditions different from, or in addition to, those set
forth in Schedule B.”

6. Paragraph 14(c) of the Plan is hereby deleted in its entirety and replaced
with the following:

“Grants of ISOs may be made under this Plan until January 22, 2019 or such
earlier date as this Plan is terminated, and grants of NQSOs and awards of
Restricted Stock and Restricted Stock Units may be made until all of the shares
of Jacobs Common Stock authorized for issuance hereunder (adjusted as provided
in Sections 5 and 12) have been issued or until this Plan is terminated,
whichever first occurs. The Plan shall terminate when there are no longer
Options or Restricted Stock Units outstanding under the Plan, or when there are
no longer shares of Restricted Stock outstanding that are subject to Forfeiture
Restrictions, unless earlier terminated by the Board or by the Committee.”

 

  7. The third row of the table set forth in Schedule A of the Plan (relating to
treatment of Options in connection with a Change in Control) is hereby deleted
in its entirety and replaced with the following:

 

Employment terminates in a Qualifying Termination within two years following a
Change in Control      All Options become immediately vested   Expires on the
earlier to occur of (1) the Option expiration date provided in the grant
agreement, or (2) two years from the date of termination

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

thereof:

 

A Change in Control occurs and Options are not assumed and continued by the
acquiring or surviving corporation in the transaction (or a parent corporation
thereof)      All Options become immediately vested   Expires on the date of the
Change in Control; provided that the Employee is given at least 15 days notice
of such termination and the opportunity to exercise outstanding Options during

thereof:
