Agreement as amended shall be referred to herein as the “Agreement”);

WHEREAS, since February 24, 2011, Executive has been acting in the capacity of
Principal Accounting Officer and Principal Financial Officer; and

WHEREAS, given the change in Executive’s role as of February 24, 2001, Executive
and Dialogic wish to amend the Agreement.

NOW, THEREFORE, in consideration of the premises and mutual covenants set forth
herein, and other consideration, the receipt of which is hereby acknowledged,
Dialogic and Executive hereby agree as follows:

 

  1. The preamble of this Amendment 2 forms an integral part of this Agreement
as if it was recited at length herein.

 

  2. Except as specifically set forth herein, the Agreement continues in full
force and effect.

 

  3.

Section 6(i)(ii) is hereby replaced in its entirety with the following:
“Constructive Dismissal” shall mean, without Executive’s express written
consent, (i) the material breach by Dialogic (or any successor thereto) of any
of its material obligations under this Agreement (including the obligation of
Dialogic to pay Base Salary), provided that such breach is not cured within
twenty (20) business days after written notice by Executive to the Chief
Executive Officer, copied to Dialogic’s General Counsel and Senior VP Human
Resources, that such breach has occurred and will serve as cause for
Constructive Dismissal, or (ii) the material reduction or diminution by the
Board of the duties, responsibilities, title, authority or reporting

that, in all material respects, are inconsistent with Executive’s position as

the period in which Dialogic is conducting a search for a new Chief Financial
Officer and that therefore should Executive resign from Dialogic no later than
December 31, 2011, such resignation will be treated as a Constructive Dismissal
for purposes of this Agreement.

 

  6. A new Section 18 is added to the Agreement as follows: “On or about

CAN$100,000 (“Retention Bonus”); provided, however, that Executive will have
been employed by Dialogic on December 31, 2011; provided, further that if
Executive is terminated by Dialogic prior to December 31, 2011 for any reason,
other than for “Cause” as defined in Section 6(i)(ii) above, within thirty
