  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On June&nbsp;3, 2008, Coherent, Inc.&#146;s (the &#147;Company&#146;s&#148;) Compensation
  and H.R. Committee (the &#147;Committee&#148;) authorized the Company to amend two of
  Luis Spinelli&#146;s stock options (the &#147;Spinelli Options&#148;) to increase the exercise
  prices of such options:&#160; an option to
  purchase 5,058 shares of Coherent common stock was amended to increase the
  exercise price from $19.77 to $24.90, and an option to purchase 14,942 shares
  of Coherent common stock was amended to increase the exercise price from $19.77
  to $24.90.&#160; Because the Spinelli Options
  were originally granted with a per share exercise price less than the fair
  market value of a share of Coherent common stock on the date of grant, such
  options may be subject to the adverse tax consequences under Section&nbsp;409A
  of the Internal Revenue Code of 1986, as amended.&#160; The Internal Revenue Service promulgated
  special transition rules&nbsp;to protect taxpayers from the adverse tax
  consequences of Section&nbsp;409A by permitting certain holders of discounted
  options to amend such option to increase the exercise price to the fair market
  value of the common stock on such options&#146; original grant date, so long as such
  amendment occurs by December&nbsp;31, 2008.&#160;
  Therefore, the Committee authorized the amendments to the Spinelli
  Options described above to avoid adverse tax consequences under Section&nbsp;409A
  to Mr.&nbsp;Spinelli.&#160; In addition, in
  order to compensate Mr.&nbsp;Spinelli for the loss of the built-in value
  associated with increasing the exercise prices of the Spinelli Options, the
  Committee authorized a cash payment to Mr.&nbsp;Spinelli of $107,730, which
  equals approximately 105% of the built-in loss of value of the Spinelli
  Options.&#160; Such payment will be made on
  the Company&#146;s first payroll date in 2009, less applicable withholdings.</font></p>

  Departure of Directors or Certain Officers;
    Election of Directors; Appointment of Certain Officers; Compensatory
    Arrangements of Certain Officers
  Compensatory Arrangements of Certain Officers
  On June 3, 2008, Coherent, Inc.'s (the "Company's") Compensation
  and H.R. Committee (the "Committee") authorized the Company to amend two of
  Luis Spinelli's stock options (the "Spinelli Options") to increase the exercise
  prices of such options:  an option to
  purchase 5,058 shares of Coherent common stock was amended to increase the
  exercise price from $19.77 to $24.90, and an option to purchase 14,942 shares
  of Coherent common stock was amended to increase the exercise price from $19.77
  to $24.90.  Because the Spinelli Options
  were originally granted with a per share exercise price less than the fair
  market value of a share of Coherent common stock on the date of grant, such
  options may be subject to the adverse tax consequences under Section 409A
  of the Internal Revenue Code of 1986, as amended.  The Internal Revenue Service promulgated
  special transition rules to protect taxpayers from the adverse tax
  consequences of Section 409A by permitting certain holders of discounted
  options to amend such option to increase the exercise price to the fair market
  value of the common stock on such options' original grant date, so long as such
  amendment occurs by December 31, 2008. 
  Therefore, the Committee authorized the amendments to the Spinelli
  Options described above to avoid adverse tax consequences under Section 409A
  to Mr. Spinelli.  In addition, in
  order to compensate Mr. Spinelli for the loss of the built-in value
  associated with increasing the exercise prices of the Spinelli Options, the
  Committee authorized a cash payment to Mr. Spinelli of $107,730, which
  equals approximately 105% of the built-in loss of value of the Spinelli
  Options.  Such payment will be made on
  the Company's first payroll date in 2009, less applicable withholdings.
  ITEM 5.03.
