Robert M. Dennerlein

[Address]

Dear Bob:

Dialogic Inc. (“Dialogic” or “Company”), is pleased to make you this offer of employment according to the following terms and conditions.

This equates to $25,000 USD per month. Statement of salary as an annual amount is not intended to and does not form a contract of employment and in no way negates the At Will Employment provisions of this offer letter.

Annual Bonus: You will be eligible to earn an annual incentive bonus that, at target levels, equals fifty percent (50%) of your base salary in the applicable performance period. Whether you receive such a bonus, and the amount of any such bonus, shall be determined by the Company’s Board of Directors (“Board”) in its sole and reasonable discretion, and shall be based on the Board’s assessment of achievement of performance objectives to be established by the Board (or duly authorized committee thereof) and the Chief Executive Officer. Any earned bonus shall be subject to standard payroll deductions and withholdings, and paid no later than March 15^th of the year following the applicable bonus year. Except as set out in the Termination/Severance Section below, you must be employed on the day that the bonus (if any) is paid in order to earn the bonus.

Payroll Period: You will be paid according to the Company’s standard payroll procedure in the United States. Payroll is currently paid bi-weekly, every other Friday. You will receive

your first paycheck on the first payroll period following either your date of hire or when the next payroll is run, whichever is applicable.

Stock Options: Provided that such grant is approved by the Company’s Board of Directors and provided you execute all necessary documentation requested by the Company, you will be issued stock options and/or Restricted Stock Units in the Company where the stock price at the date of issue multiplied by the number of options and/or Restricted Stock Units you receive equals a total of $300,000. This grant will be subject to vesting and will be made pursuant to the terms of the Company’s stock option plan in effect at the date of grant and as such stock option plan may be modified from time to time.

Vacation: We agree to provide you with 20 vacation days per calendar year. Your number of vacation days in the initial calendar year of your employment is prorated to your Start Date. Should the Company’s policy change so that it would entitle you to more than 20 vacation days per year, you will be covered by such policy, which would be based on your Start Date.

Personal Days: In January of each calendar year, the Company grants six days of personal leave to all employees to be used during the remainder of the calendar year, as per Company policy. In your initial year of employment, these six personal days are pro-rated based on your actual Start Date. While this time is intended primarily to be used in lieu of sick leave, it is your time to manage as you see fit. Personal days may not be carried forward from year to year. Unused personal days may be banked as sick leave, to a maximum of 30 days total, for use for yourself or a family member, but they are not considered “earned time off” and are not compensated in the event of termination of your employment with Company. You will be granted two (2) personal days to use during the remainder of 2013.

Health Insurance and Benefits Program: A Human Resources Representative will answer any questions you may have about the benefits offered. As a condition of employment, you are expected to complete all documents provided by the company as part of your employment conditions in a timely manner, as benefits commence with the first of the month following your first day of employment.

Employee Stock Purchase Plan: Dialogic currently offers its full-time employees the opportunity to participate in its Employee Stock Purchase Plan and you will have such opportunity for so long as the Employee Stock Purchase Plan is in effect. Details for participation in the Employee Stock Purchase Plan are available through Company’s Human Resources Department.

401(k): You will automatically be enrolled in the Company’s 401(k) plan at the minimum contribution level of 3% unless you opt out of the 401(k) plan.

                    Initialed                             

Travel: The position you are accepting is a position that requires travel. You agree to comply with the Company’s travel policies as published on the Company intranet, and as otherwise communicated by the Company from time to time.

Full Time Work/Non-Competition and Non-Solicitation Agreement: You agree to devote your full time, attention, and energies to the business of the Company. To this end, you promise not to engage in any other employment, whether or not for profit, while in the employ of the Company to the extent that such employment would in any way interfere with your duties with Company or limit your time or commitment to this position. In addition you agree to enter into the Non-Competition and Non-Solicitation Agreement attached hereto as Exhibit C and which forms an integral part of this offer letter.

Law Applicable: All terms of this offer letter shall be interpreted under the laws of the State of New Jersey.

At-Will Employment: Although we are looking forward to a mutually rewarding relationship, the employment you are being offered is at-will. This means that just as you are free to leave your employment with us at any time and for any reason, the Company has the right to terminate their employment relationship with you at any time and for any reason. You also understand that although the general terms and conditions that will be in effect at the outset of your employment are set forth in this letter, the Company reserves the right to change, modify or eliminate any of the terms, conditions, and/or benefits described in this offer letter and/or their policies at any time, at their sole discretion and without any prior notice. Furthermore, the at-will nature of your employment may not be changed by any policy, practice or representation made by the Company, except by a written employment contract signed by you and an Officer of the Company.

Termination; Severance:

(a) Resignation without Good Reason; Termination For Cause; Termination Due to Death or Disability. If, at any time, you resign your employment without Good Reason (as defined herein), or if the Company terminates your employment for Cause (as defined herein), or if either party terminates your employment as a result of your death or disability, you will receive your base salary accrued through your last day of employment and any earned, unused vacation (if applicable) accrued through your last day of employment. In any of these events, you will not be entitled to any other form of compensation from the Company, including any severance benefits. In the event that you voluntarily terminate your relationship with the Company, you agree to give the Company a minimum of two (2) months’ notice (“Notice Period”) that you intend to separate from the Company, and during that period, you agree to diligently exercise your full job responsibilities, including providing a successful turnover to either your direct manager or to any designee provided by the Company at the end of such Notice Period. The Company

                    Initialed                             

reserves the right to advise you that the Notice Period shall be shorter in the event it does not need your services throughout the entire Notice Period.

(b) Termination without Cause; Resignation for Good Reason. If, at any time, either (x) the Company terminates your employment without Cause, and other than if your employment terminates as a result of your death or disability, or (y) you resign for Good Reason, and provided such termination constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “Separation from Service”), then subject to your satisfaction of the conditions below, you will be entitled to receive (collectively, the “Severance Benefits”):

(i) Salary Continuation. Twelve (12) months of your then current Base Salary, ignoring any decrease in Base Salary that forms the basis for Good Reason, less all applicable withholdings and deductions (regardless of the date of termination the “Salary Continuation”), paid in equal installments on the Company’s normal payroll schedule for the first twelve (12) months following your Separation from Service (provided that no payments will be made prior to the 60^th day following your Separation from Service, and on such 60^th day, the Company will pay you in a lump sum the Salary Continuation that you would have received on or prior to such date under the original schedule but for the delay while waiting for the 60^th day in compliance with Code Section 409A).

(ii) Annual Bonus. A lump sum payment equal to the Annual Bonus that you would have earned, had you remained employed through the payment date, based on the actual achievement of the performance goals, as determined by the Board, but pro-rated based on the number of days you served as an active employee in the year of termination, paid in a lump sum on the date that the Company pays the Annual Bonus to active employees for that year, but in all cases not later than March 15 of the year following the year of termination.

(iii) Payments for COBRA. If you timely elect continued coverage under COBRA for yourself and your covered dependents under the Company’s group health plans following your Separation from Service, then the Company will pay to you the same dollar amount of the health insurance premiums that it was paying on your behalf immediately prior to your Separation from Service, from that date until the earliest of (A) the close of the 12th month period following your Separation from Service, (B) the expiration of your eligibility for the continuation coverage under COBRA, or (C) the date when you become eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment (such period from the termination date through the earliest of (A) through (C), the “COBRA Payment Period”). The Company will make these payments, subject to applicable tax deductions, during each month in which you receive the coverage in the check that contains with your Salary Continuation payment for that month. On the 60^th day following your Separation from Service, the Company will make the first payment under this clause equal to the aggregate amount of payments that the Company would have paid through such date had such payments commenced on the Separation from Service, with the balance of the payments paid thereafter on the schedule described above. If you become eligible for coverage under another employer’s group

                    Initialed                             

health plan or otherwise cease to be eligible for COBRA during the period provided in this clause, you must immediately notify the Company of such event, and all payments and obligations under this clause will cease.

(c) Termination without Cause; Resignation for Good Reason – Change of Control. If on or within twelve (12) months following the closing of a future Change of Control, either (x) the Company or a successor corporation terminates your employment without Cause and other than as a result of your death or disability, or (y) you resign for Good Reason (as defined herein), and provided such termination constitutes a Separation from Service, then, in addition to receiving the Severance Benefits, you will also receive (subject to your satisfaction of the conditions to receiving the Severance Benefits) the acceleration of the vesting of all of your then-outstanding compensatory stock grants as of the date of termination.

(a) Change of Control. “Change of Control” will mean the consummation of any one of the following events, but only if such event also constitutes a “change in the ownership or effective control of the corporation or in the ownership of a substantial portion of the assets of the corporation” as defined under Treasury Regulation Section 1.409A-3: (a) a sale, lease or other disposition of all or substantially all of the assets of the Company; (b) a consolidation or merger of the Company with or into any other corporation or other entity or person, or any other corporate reorganization, in which the shareholders of the Company immediately prior to such consolidation, merger or reorganization, own less than 50% of the Company’s outstanding voting power of the surviving entity (or its parent) following the consolidation, merger or reorganization or (c) any transaction (or series of related transactions involving a person or entity, or a group of affiliated persons or entities) in which in excess of fifty percent (50%) of the Company’s outstanding voting power is transferred (excluding (i) any consolidation or merger effected exclusively to change the domicile of the Company, or (ii) any transaction or series of transactions with any then-existing shareholder of the Company or their affiliates or any holder of the Company’s debt principally for bona fide equity financing purposes in which cash is

                    Initialed                             

received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof).

(b) Cause. For purposes of this offer letter, “Cause” will mean one or more of the following: (i) your conviction of a felony; (ii) your commission of any act of fraud with respect to the Company; (iii) any intentional misconduct by you that has a material adverse effect upon the Company’s business; (iv) your breach of any fiduciary or contractual obligation that you owe to the Company that has a material adverse effect upon the Company’s business; (v) willful misconduct or gross negligence in the performance of your duties hereunder, including (without limitation) your refusal to comply in any material respect with the legal directives of the Board or the CEO, so long as such directives are not inconsistent with your position and duties, provided that if such willful misconduct or gross negligence is capable of cure, the Company provides you with thirty (30) days written notice to cure such willful misconduct or gross negligence.

(c) Good Reason. For the purposes of this offer letter, “Good Reason” will mean your resignation in writing from all positions you then hold with the Company as a result of any one of the following events which occurs without your consent and provided you notify the Company in writing, within thirty (30) days after the occurrence of one of the following actions, that you intend to terminate your employment no earlier than thirty (30) days after providing such notice, and the Company fails to cure such actions within thirty (30) days after receipt of such notice, and such resignation is effective not later than sixty (60) days (or shorter timeframe if mutually agreed to in writing by you and the Company) after the expiration of the applicable thirty (30) day cure period: (i) a material reduction of your then current Base Salary, which the parties agree is a reduction by 10% or more; (ii) any material diminution of your duties, responsibilities, or authority to a level below that of an officer of the Company, excluding for this purpose (1) an isolated or inadvertent action not taken in bad faith that is remedied by the Company immediately after notice thereof is given by you, (2) any change in your title, duties, responsibilities or authority if you are given or you retain other officer level duties within the Company and (3) a reduction in duties, position or responsibilities solely by virtue of the Company being acquired and made part of a larger entity, whether or not public, provided you retain duties, position or responsibilities consistent with that of a senior executive of the Company or the larger entity (for example, there will not be Good Reason if Executive is not made the Chief Financial Officer of the acquiring corporation, but instead retains duties, position or responsibilities consistent with that of a senior executive of the Company ); or (iii) any requirement that you relocate to a work site that results in a material adverse change in the geographic location at which you most often provide services, which the parties agrees is an increase in your one-way commute by more than fifty (50) miles.

(d) Code. For the purposes of this offer letter, “Code” means the Internal Revenue Code of 1988, as amended.

                    Initialed                             

280G Best After Tax. If any payment or benefit you would receive from the Company or otherwise in connection with a change of control or other similar transaction (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment will be equal to the Reduced Amount. The “Reduced Amount” will be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax, or (y) the largest portion, up to and including the total, of the Payment, whichever amount ((x) or (y)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt of the greatest economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a Reduced Amount will give rise to the greater after tax benefit, the reduction in the Payments will occur in the following order: (a) reduction of cash payments; (b) cancellation of accelerated vesting of equity awards other than stock options; (c) cancellation of accelerated vesting of stock options; and (d) reduction of other benefits paid to you. Within any such category of payments and benefits (that is, (a), (b), (c) or (d)), a reduction will occur first with respect to amounts that are not “deferred compensation” within the meaning of Section 409A and then with respect to amounts that are. In the event that acceleration of compensation from your equity awards is to be reduced, such acceleration of vesting will be canceled, subject to the immediately preceding sentence, in the reverse order of the date of grant.

Section 409A. Notwithstanding anything to the contrary herein, it is intended that the Severance Benefits and other payments payable under this offer letter satisfy, to the greatest extent possible, the exemptions from the application of Code Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5), and 1.409A-(b)(9) and this offer letter will be construed to the greatest extent possible as consistent with those provisions. For purposes of Section 409A of the Code and the regulations and other guidance thereunder and any state law of similar effect (collectively “Section 409A”) (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), all payments made under this offer letter, including without limitation your right to receive any installment payments under this offer letter (whether severance payments, reimbursements or otherwise) will be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder will at all times be considered a separate and distinct payment.

It is intended that any severance payment and any other benefits provided hereunder that are not exempt from application of Section 409A will be interpreted and administered so as to comply with the requirements of Code Section 409A to the greatest extent possible, including the requirement that, notwithstanding any provision to the contrary in this offer letter, if you are deemed by the Company at the time of your Separation from Service to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and to the extent payments due to you upon a Separation from Service are deemed to be “deferred compensation”, then to the extent delayed commencement of any

                    Initialed                             

portion of such payments (or delayed issuance of any shares subject to stock awards that are not themselves exempt from Code Section 409A) is required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i) and the related adverse taxation under Section 409A, such payments will not be provided to you (or such shares issued) prior to the earliest of (i) the expiration of the twelve-month period measured from the date of your Separation from Service with the Company, (ii) the date of your death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day following the expiration of such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph will be paid in a lump sum to you, and any remaining payments due will be paid as otherwise provided herein or in the applicable agreement. No interest will be due on any amounts so deferred.

If such notice is provided by you it shall be sent to the Dialogic Human Resources Department, 1515 Route 10 East, Parsippany, NJ 07054 with a copy to the Dialogic Legal Department at 6700 Cote-de-Liesse, Suite 100, St. Laurent, Quebec, CANADA H4T 2B5 or to such other corporate representative as may be designated from time to time.

IT IS UNDERSTOOD AND AGREED THAT YOUR EMPLOYMENT WITH DIALOGIC IS AT-WILL AND MAY BE TERMINATED AT ANY TIME WHETHER WITH OR WITHOUT CAUSE.
