Item 1.01    Entry into a Material Definitive Agreement.


     On March 23, 2006, the  stockholders of Keynote Systems,  Inc.  ("Keynote")
approved  amendments to Keynote's 1999 Equity  Incentive  Plan regarding  equity
compensation  awards to  Keynote's  non-employee  directors.  These  changes  in
director compensation became effective immediately after such approval:


     o    Upon being  appointed to the Board of  Directors,  a new  non-employee
          director  will be  granted  an option  to  purchase  60,000  shares of
          Keynote  common stock.  Such options shall vest over four years,  with
          the  option  becoming  vested  as to  15,000  shares  on the one  year
          anniversary  of the  date of  grant  (or the next  annual  meeting  of
          stockholders,  if earlier), and the remaining 45,000 shares vesting on
          a monthly basis  thereafter.  The options will have an exercise  price
          equal  to the  closing  price of the  common  stock on the date of the
          grant.


     o    The aggregate  amount of shares of Keynote common stock a non-employee
          director  may  receive in any fiscal year  pursuant  to  discretionary
          grants is limited to 40,000 shares.

     Such options will  accelerate in full upon (a) a dissolution or liquidation
of Keynote,  (b) a merger or consolidation in which Keynote is not the surviving
corporation   (other  than  a  merger  or  consolidation   with  a  wholly-owned
subsidiary,  a reincorporation of Keynote in a different jurisdiction,  or other
transaction  in which  there is no  substantial  change in the  stockholders  of
Keynote or their relative stock holdings),  (c) a merger in which Keynote is the
surviving  corporation but after which the  stockholders of Keynote  immediately
prior to such merger (other than any stockholder  that merges,  or which owns or
controls another  corporation that merges, with Keynote in such merger) cease to
own  their  shares  or  other  equity  interest  in  Keynote,  (d)  the  sale of
substantially  all of the assets of Keynote,  or (e) the  acquisition,  sale, or
transfer of more than 50% of the  outstanding  shares of Keynote by tender offer
or similar transaction.





                                    SIGNATURE

     Pursuant to the  requirements  of the Securities  Exchange Act of 1934, the
registrant  has duly  caused  this  report  to be  signed  on its  behalf by the
undersigned thereunto duly authorized.
