          Agreement  dated as of the first day of January 1997 between  Dialogic
Corporation,  a New Jersey corporation having its principal place of business in
Parsippany, New Jersey, (the "Company") and Howard G. Bubb currently residing at
21 Fernwood Place, Mountain Lakes, NJ 07046 (the "Employee")

                                  WITNESSETH:

          WHEREAS,  the Company considers the establishment and maintenance of a
sound and vital  management to be essential to protecting and enhancing the best
interests of the Company and its stockholders; and

          WHEREAS,  as of the date of this  Agreement  Employee is the President
and Chief  Executive  Officer of the Company and has  developed  an intimate and
thorough knowledge of the Company's business methods and operations; and

          WHEREAS,  the retention of Employee's  services,  for and on behalf of
the Company, is materially  important to the preservation and enhancement of the
value of the Company's business; and

          WHEREAS,  the Company is desirous of extending  Employee's  employment
upon the terms and  conditions  contained  herein;  and  Employee is desirous of
continuing  to be  employed  by the  Company in  accordance  with such terms and
conditions.

          NOW,  THEREFORE,  in  consideration  of the mutual  promises set forth
herein, and for other good and valuable consideration,  the receipt and adequacy
of which is hereby acknowledged, the parties hereto do hereby agree as follows:

          1.  Employment.  The Company  hereby  agrees to employ  Employee,  and
Employee agrees to be employed by the Company in accordance with and pursuant to
the terms and conditions set forth below.

          2. Term of Employment.  This Agreement shall be for an initial term of
three (3) years.  Upon the third anniversary  hereof,  (and upon each successive
anniversary  thereafter) this Agreement shall be automatically renewed for a one
(1) year term, commencing on the date of each such renewal,  unless either party
hereto  notifies the other in writing of its intent not to renew this  Agreement
upon not less than six (6) months  notice prior to the renewal  date hereof.  In
the event  either  party  gives the other  proper  notice of  non_renewal,  this
Agreement  shall  only  continue  for the  balance  of the then  existing  term.
Notwithstanding   anything  contained  herein  to  the  contrary,  any  term  of
employment may be earlier terminated as provided in Section 8 hereof.

          3. Position and Responsibilities.

          (a) Employee will occupy the position of President and Chief Executive
Officer of the  Company.  During  such  period he occupies  said  position,  the
Company shall apply its best efforts to effectuate the nomination of Employee to
the Company's Board of Directors  subject to the terms of the Company's  By-laws
and Articles of Organization, as amended from time to time.

          (b) Employee will report  directly to the Board of Directors and shall
have such  duties and  responsibilities  as are set forth in the  By-laws of the
Company, which duties and responsibilities shall include, but not be limited to,
overall management  responsibilities for the operation and administration of the
Company  as well as such  other  duties and  responsibilities,  consistent  with
Employee's  position  as  President  and  Chief Executive  Officer,  as shall be
defined by the Board of Directors.

          (c) Employee will be expected to be in the full-time employment of the
Company,  to devote  substantially  all of his business time and attention,  and
exert his best efforts to the performance of his duties hereunder,  and to serve
the  Company  diligently  and to the  best of his  ability;  provided,  however,
nothing  set  forth  herein  shall  prohibit  Employee  from  engaging  in other
activities  to the extent  that such  activities  do not  impair the  ability of
Employee to perform his duties and obligations under this Agreement.

          4. Compensation. The Company shall pay to Employee a salary (the "base
salary")  at an annual  rate of  $275,000,  subject  to  deductions  for  social
security,  payroll  withholding  and all other  legally  required or  authorized
deductions and withholdings. Employee's salary shall be payable at the same time
and on the same basis as the Company  pays its  executive  employees in general.
The Board of Directors  shall review  Employee's  base salary no less frequently
than annually.  Unless Employee  consents,  in no event shall his base salary be
decreased during his period of employment.

          5.  Quarterly  Incentive  Payments.  In  addition  to the base  salary
referenced in Section 4, Employee shall be entitled to quarterly  bonuses if the
Company achieves its quarterly  performance goals and Employee  satisfies agreed
upon discreet  goals/objectives  to be  established by the Board of Directors at
its sole and absolute  discretion in consultation  with Employee.  The amount of
such bonuses,  if any,  shall be  determined  by the Board of Directors.  Unless
Employee  consents,  in no event shall his target bonus opportunity be decreased
during his period of employment.

          6. Stock  Options  and Other Long Term  Incentive  Programs.  Employee
shall continue to be entitled to receive stock options pursuant to the Company's
1988 Incentive  Compensation Plan and the 1997 Incentive Benefit Plan, including
any amendments thereto.  The number of shares covered by any such option grants,
the  exercise  price per share and other  terms and  conditions  governing  such
options shall be determined by the  Compensation  Committee,  subject however to
the terms of such Plans,  and to the extent  applicable,  the provisions of this
Agreement.  In addition,  Employee  shall also be eligible to participate in any
other long term incentive program covering executive employees.  For purposes of
this Section 6, "cause" as used in the Company's  Incentive  Benefit Plans shall
be determined with reference to Section 8(b) of this Agreement.

          7. Benefits; Expenses; Vacations.

          (a) Employee  shall be entitled to receive the same standard  employee
benefits,  perquisites and services as other executive  employees of the Company
receive.  Employee  shall also be  entitled to fully  participate  in all of the
Company's  future  employee  benefit  programs,   perquisites  and  services  in
accordance with their then existing terms.

          (b) Employee shall be entitled to  reimbursement  for all approved and
reasonable travel and other business expenses incurred by him in connection with
his  services  to the  Company  pursuant  to the  terms of this  Agreement.  All
business expenses for which Employee seeks  reimbursement from the Company shall
be adequately documented by Employee in accordance with the Company's procedures
covering expense  reimbursement,  and in compliance with regulations of the U.S.
Internal  Revenue  Service.  In the  event  any  such  reimbursements  shall  be
includable in Employee's  income, the Company shall pay Employee such additional
amounts as are  necessary so that after taking into account any taxes payable on
such  reimbursements,  the Employee is in the same  after-tax  position he would
have been had such reimbursement not been so includable.

          (c) Employee shall be entitled to vacation days in accordance with the
Company's employment policies and practices applicable to executive employees of
the Company, as such policies and practices are from time to time in effect.

          8. Employment Termination. The employment of Employee pursuant to this
Agreement shall terminate upon the occurrence of any of the following:

          (a) Expiration of the employment period set forth in Section 2, unless
the  employment  of  Employee  is  continued  pursuant  to  this  Agreement,  or
otherwise;

          (b) For cause upon written notice by the Company to the Employee.  For
the  purposes  of this  Section 8(b),  cause  for  termination  shall be  fraud,
embezzlement, or other acts in intentional disregard of the Company's interests.

          (c) Death or thirty (30) days after the  disability  of Employee.  For
purposes of this Agreement,  the term  "disability"  shall mean the inability of
Employee  due to a  physical  or  mental  disability,  for a  period  of  ninety
(90) days  (whether  or not  consecutive)  during any three  hundred  sixty five
(365) day period to perform the services  contemplated  under this Agreement.  A
determination  of disability  shall be made by a physician  satisfactory to both
Employee and the Company; provided,  however, if Employee and the Company do not
agree on a physician, Employee and the Company shall each select a physician and
these two together shall select a third  physician,  and such third  physician's
determination as to disability shall be binding on all parties.

          (d) At the election of either party without cause,  upon not less than
six (6) months prior written notice of termination.

          (e) At the election of Employee if there is a material  breach of this
Agreement by the Company.

          9. Effect of Termination.

          (a)  Termination  for Cause or at Election of  Employee.  In the event
Employee's  employment is terminated  for cause  pursuant to Section 8(b), or at
the  election of the  Employee  pursuant to Section  8(a) or Section  8(d),  the
Company shall pay Employee within thirty (30) days of his termination a lump-sum
equal to his base salary (less applicable  deductions),  incentive  payments and
benefits, perquisites and services otherwise payable to him through the last day
of his actual employment by the Company, or such other period as may be required
by law.

          All previously  granted but unexercised vested stock options which are
outstanding  on  Employee's  date of  termination  shall remain fully vested and
exercisable  in  accordance  with their terms and all  non-vested  stock options
shall be  canceled.  In addition,  any other  vested  amounts or awards to which
Employee may be entitled under any other long term incentive program  referenced
in  Section  6  shall  be  paid  to  Employee  within  thirty  (30)  days of his
termination and all non-vested amounts or awards shall be canceled.

          (b)  Termination  at the Election of the Company or at the Election of
Employee for  Sufficient  Reason or Upon a Change of Control.  In the event that
Employee's  employment is terminated at the election of the Company  pursuant to
Section 8 (a) or Section 8(d), or at the election of the Employee for sufficient
reason pursuant to Section 8(e), or upon a Change of Control pursuant to Section
10, the Company shall pay Employee  within thirty (30) days of his termination a
lump-sum equal to his then base salary (less applicable  deductions),  incentive
payments and benefits, perquisites and services otherwise payable to him through
the later of: (i) the last day of the term of this Agreement pursuant to Section
2 or (ii) the period ending twelve (12) months after his termination. Additional
base salary (less  applicable  deductions)  shall be payable on a monthly basis,
commencing  on the  later  of the  two (2)  dates  referenced  in the  preceding
sentence and ending on the date of Employee's employment with an employer othe r
than the Company, or the date of his self-employment;  provided,  however, in no
event shall the total period of base salary  payments  under this Section  9(b),
exceed  twenty-four  (24)  months,  unless  the  last  day of the  term  of this
Agreement is more than twenty-four (24) months after Employee's termination.

          The incentive payments referred to in the preceding paragraph shall be
determined on a calendar quarter basis as follows:

          For the last full calendar  quarter in which Employee was employed for
the entire quarter, the incentive payment shall be equal to the amount otherwise
payable to the Employee in accordance with Section 5 of this Agreement.

          For each other full calendar quarter with respect to which Employee is
entitled to incentive  payments under the first paragraph of this Section 9 (b),
the incentive  payment shall be equal to the greater of: (i)  Employee's  target
incentive  award  for the  quarter  in which  Employee  has a  termination  from
employment or (ii) twenty_five percent (25%) of his actual incentive payment for
the immediately preceding calendar year.

          If the period with respect to which  Employee is entitled to incentive
payments  under the first  paragraph  of this  Section 9 (b) ends on a day other
than the last day of a calendar  quarter,  the incentive payment with respect to
such partial calendar quarter shall be an amount equal to the amount  determined
immediately  above  with  respect to full  calendar  quarters,  multiplied  by a
fraction the numerator of which is the number of days in such calendar  quarter,
with  respect to which  Employee is entitled to payment and the  denominator  of
which is the total number of days in such calendar quarter.

          All  previously  granted,  but  unexercised  stock  options  which are
outstanding  on  Employee's  date of  termination  shall  be  fully  vested  and
exercisable as of such date,  and shall be exercisable in accordance  with their
terms, or for a period of twelve (12) months after such  termination,  whichever
period is longer.  In addition,  any amounts or awards to which  Employee may be
entitled  under any other long term  incentive  program  referenced in Section 6
(whether or not vested)  shall be paid to Employee in a lump_sum  within  thirty
(30) days of his termination.

          (c)  Termination  for Death or  Disability.  In the  event  Employee's
employment is terminated  by death or disability  pursuant to Section 8(c),  the
Company shall pay to the estate of Employee,  or to Employee, as the case may be
, within thirty (30) days of Employee's death, or disability a lump-sum equal to
his then base salary and benefits, perquisites and services otherwise payable to
him through the last day of the term of this Agreement pursuant to Section 2, or
such other  period as may be required  by law;  provided,  however,  any amounts
payable  hereunder as a result of Employee's  disability shall be reduced by any
Company  provided  long term  disability  payments  received by him. The Company
shall also pay to the estate of  Employee,  or to  Employee  as the case may be,
within such thirty (30) day period,  an incentive  payment pursuant to Section 5
determined as if Employee were neither dead, nor disabled on the last day of the
calendar  quarter,  prorated  for the quarter in which the  Employee's  death or
disability occurs, or such longer period as may be required by law.

          All vested stock options shall remain  exercisable in accordance  with
their terms and all non-vested stock options shall be canceled. In addition, any
amounts or awards to which  Employee  may be entitled  under any other long term
incentive  program  referenced in Section 6 as a result of  Employee's  death or
disability, shall be paid to the estate of Employee, or to Employee, as the case
may be, in a lump-sum within thirty (30) days of Employee's  death or sixty (60)
days after he terminates for disability.

          10.  Change of  Control.  If a Change of Control  Event (as defined in
Section 14 of the 1997 Incentive Benefit Plan of Dialogic  Corporation)  occurs,
and as a result thereof  Employee  terminates his employment  within twelve (12)
months of the change, because:  (a) there is a significant  diminution,  without
mutual  agreement  of the  parties,  in  the  nature  and  scope  of  Employee's
authority,  power,  functions or duties, or (b) the Company assigns to Employee,
without  mutual  agreement  of the  parties  substantial  additional  duties  or
responsibilities  which are  inconsistent  with the duties of the Employee under
this Agreement,  or (c) the Company transfers  Employee without mutual agreement
of the parties to an office more than twenty_five  (25) miles from the principal
office of the  Company;  or Employee is  terminated  for reasons  other than for
cause  within  such  twelve  (12) month  period,  Employee  shall be entitled to
payment pursuant to Section 9(b) hereof.  In addition,  any expenses incurred by
Employee in connection  with a sserting his rights under this  Agreement  upon a
Change of Control shall be paid by the Company as and when  Employee  receives a
judgment in his favor from a court of competent jurisdiction.

          11.  Gross-up  Provision.  If any portion of any payments  received by
Employee  from  the  Company  (whether  payable  pursuant  to the  terms of this
Agreement or any other plan,  agreement  or  arrangement  with the Company,  its
successors  or any  person  whose  actions  result in a change of control of the
Company) shall be subject to tax imposed by Section 4999 of the Internal Revenue
Code of 1986, as amended or any successor statutory provision, the Company shall
pay to Employee such additional  amounts as are necessary so that,  after taking
into  account  any tax  imposed  by  Section 4999  (or any  successor  statutory
provision),  and any federal and state income taxes payable on any such tax, the
Employee  is in the same  after-tax  position  that he would  have  been if such
Section 4999 or any successor  statutory provision did not apply and no payments
were made pursuant to this Section 11.

          12.  Confidentiality.   The  parties  acknowledge  that  Employee  has
previously  entered into an Amended  Employment  Agreement as of January 1, 1993
(the January 1993  Agreement) in connection  with  Employee's  employment by the
Company,  and that such Agreement at paragraphs 9 through 16 imposes  restraints
necessary for the reasonable and proper protection for the Company and that each
and every one of said  restraints is  reasonable  in respect to subject  matter,
length of time, and area.  Accordingly,  such paragraphs are incorporated herein
and made a part  hereof  as if set forth  herein,  in their  entirety  and shall
continue for a period of (i) three (3) years from and after the date hereof,  or
(ii)  three  (3) years  after  the end of any  employment  relationship  between
Employee and the Company  (including  any affiliate of the  Company),  whichever
period is longer.

          13.  Waivers.  This  Agreement  may be  modified,  and the  rights and
remedies of any provision hereof may be waived, only in writing,  signed by both
the Company and  Employee.  No waiver by either party of any breach by the other
or any  provision  hereof  shall be  deemed to be a waiver of any later or other
breach hereof, or as a waiver of any other provision of this Agreement.

          14.  Governing  Law. This  Agreement  shall be construed in accordance
with the laws of the State of New Jersey.

          15. Severability.  In case any one or more of the provisions contained
in this  Agreement  for any  reason  shall  be held to be  invalid,  illegal  or
unenforceable in any respect,  such invalidity,  illegality or  unenforceability
shall not affect any other provision of this Agreement, but this Agreement shall
be construed as if such invalid,  illegal or unenforceable  provisions had never
been contained herein.

          16.  Termination  of All  Prior  Agreements;  Entire  Agreement.  Upon
execution of this Agreement, all prior employment agreements shall be terminated
and of no further  force or effect,  except for  paragraphs  9 through 16 of the
January  1993  Agreement,  which  are  incorporated  herein by  reference.  This
Agreement constitutes the entire agreement and understanding between the Company
and Employee  with respect to the subject  matter hereof and supersede any other
prior agreements or understandings, whether oral or written.

          17. Expenses.  The Company shall reimburse Employee for any reasonable
expenses  incurred  by  Employee  in  connection  with the  negotiation  of this
Agreement.

          18. Notices.  Any notice required or permitted to be given pursuant to
this Agreement shall be in writing, and sent to the party for whom (or which) it
is  intended at the address of such  parties  set forth below by  registered  or
certified mail, return receipt requested,  or at such other address either party
shall  designate by notice to the other in the manner provided herein for giving
notice.
