Notwithstanding any other provision of this Plan to the contrary, if a Participant has executed an employment agreement or advisory agreement with SenDEC with Company approval, then such employment agreement or advisory agreement shall control with respect to such individual’s status as a Participant under this Plan and right to receive a Bonus Payment on a Payment Date. Any Bonus Payment to a Participant shall be made in the calendar year in which the Bonus Period ends, and no later than October 31 of such calendar year. In no event shall a Bonus Payment be paid in the tax year prior to the tax year in which it is earned.

(b) Except with respect to the Key Participants and the Additional Participants, for whom the Target Bonus Percentage remains fixed as set forth in Exhibit A, the amount of a Bonus Payment on any Bonus Period to any other Participant shall be determined as follows: within forty five (45) days after the end of each Bonus Period in which Target EBITDA has been reached, the SenDEC Representative shall prepare a proposed list of the Bonus Payments to be paid to Participants from the Bonus Pool and shall submit that list to the Plan Administrator for approval. The Plan Administrator shall either approve that list or, if such list is not approved, consult in good faith with the SenDEC Representative, and prepare a revised list, all of which shall happen prior to the date on which the Actual EBITDA Performance is determined in accordance with Section 4.1(a), and the persons on such list shall be considered Participants hereunder for such Bonus Period.

3.2 Eligibility. Except where a Participant has executed an employment agreement or advisory agreement with SenDEC with Company approval, in which case such employment or advisory agreement shall control, each Participant will remain eligible to participate, if,: (i) the individual has not disclosed to any unauthorized person or entity any information regarding this Plan and has not violated any other confidentiality agreement between the individual and the

3

Company or SenDEC; (ii) the individual has not engaged in any theft, fraud, embezzlement, dishonesty or similar conduct which has or is likely to result in material damage to the Company or SenDEC or any of their respective customers, members or subsidiaries; (iii) the individual has not, after the Closing, been convicted of, or pled guilty or no contest to a felony or a crime involving fraud; and (iv) the individual is otherwise not in material breach of the terms and conditions of all agreements Participant has with the Company or SenDEC. The eligibility determination under this Section 3.2 shall be made by the Plan Administrator, who shall consider in good faith any input provided by the SenDEC Representative with respect to such determination.

3.3 Termination of Plan Benefits. The Plan Administrator, who shall consider in good faith any input provided by the SenDEC Representative with respect to such matter, shall have the right to terminate a Participant’s participation in the Plan if the Participant’s employment with SenDEC terminates for any reason, provided, however, if the Participant has an employment agreement with SenDEC with Company approval, such employment agreement will control the termination of benefits under this Plan.

SECTION 4 – PLAN BENEFITS.

4.1 Determination of Actual Bonus Amounts.

(a) Within forty five (45) days after the end of each Bonus Period, the SenDEC Representative shall prepare and deliver to the Plan Administrator an accounting of the Actual EBITDA Performance recognized by SenDEC during the relevant Bonus Period. Within fifteen (15) days following receipt of the Actual EBITDA Performance calculations from the SenDEC Representative, the Plan Administrator will either accept the accounting or notify the SenDEC Representative that it is rejecting such accounting. In its rejection notice to the SenDEC Representative, the Plan Administrator shall specify the reasons for such rejection. If the Actual EBITDA Performance accounting is rejected, within fifteen (15) days of the notice of rejection, the SenDEC Representative and the Plan Administrator shall select a mutually satisfactory expert to determine the Actual EBITDA Performance for the Bonus Period in question and such determination shall be binding on all parties. The Company shall bear the costs of such expert. Any determination made by such expert shall be made within twenty (20) days after such expert is selected and in no event later than October 20 of the calendar year in which such Bonus Period ends.

(b) The Company will pay the Actual Bonus Amount with respect to performance for the First Bonus Period, Second Bonus Period, Third Bonus Period and Cumulative Milestone Period as follows:

(i) If 100% of the EBITDA Target is achieved in any Bonus Period, then the Actual Bonus Amount shall be equal to the Maximum Bonus Amount for that Bonus Period.

(ii) Solely with respect to the First Bonus Period, Second Bonus Period and Third Bonus Period, if at least 92% but less than 100% of the EBITDA Target is achieved in any of those Bonus Periods, then the Actual Bonus Amount for such

4

Bonus Period shall equal the product of (x) the Maximum Bonus Amount and (y) the Participation Percentage (See Exhibit B). With respect to such Bonus Period, the excess, if any of (x) the Maximum Bonus Amount for that Bonus Period over (y) the Actual Bonus Amount calculated under this Subsection (ii) for that Bonus Period, will be forfeited.

(iii) Solely with respect to the First Bonus Period, Second Bonus Period and Third Bonus Period, if SenDEC achieves less than 92% of the EBITDA Target in any of those Bonus Periods, then no Actual Bonus Amount will be paid with respect to such Bonus Period and the Maximum Bonus Amount will be forfeited.

(iv) Solely with respect to the Cumulative Milestone Period, if at least 80% but less than 100% of the EBITDA Target is achieved in the Cumulative Milestone Period, then the Actual Bonus Amount for the Cumulative Milestone Period shall equal the product of (x) the Maximum Bonus Amount and (y) the Participation Percentage (See Exhibit B). With respect to the Cumulative Milestone Period, the excess, if any of (x) the Maximum Bonus Amount for that Bonus Period over (y) the Actual Bonus Amount calculated under this Subsection (ii) for the Cumulative Milestone Period, will be forfeited.

(v) Solely with respect to the Cumulative Milestone Period, if SenDEC achieves less than 80% of the EBITDA Target in the Cumulative Milestone Period, then no Actual Bonus Amount will be paid with respect to the Cumulative Milestone Period and the Maximum Bonus Amount will be forfeited.

(vi) For the avoidance of doubt, in the Cumulative Milestone Period, the EBITDA Target for the Cumulative Milestone Period is equal to the sum of the EBITDA Targets for the First Bonus Period, Second Bonus Period and Third Bonus Period and the Actual EBITDA Performance is equal to the sum of the Actual EBITDA Performance for each of the First Bonus Period, Second Bonus Period and Third Bonus Period for purposes of determining the eligibility for the Maximum Bonus Amount in accordance with Sections 4.1(b)(i), (ii) and (iii).

An Example of the calculation of the Actual Bonus Amounts hereunder is attached hereto as Exhibit C.

(c) Any Actual Bonus Amount provided under this Section 4 shall be paid pursuant to the time and form of payment provisions of Section 5.

SECTION 5 – TIME AND FORM OF PAYMENTS.

5.1 General Rules.

(a) Within 15 days after the date the Plan Administrator and the SenDEC Representative agree on the Actual EBITDA Performance for the relevant Bonus Period in accordance with Section 4.1(a), but in no event later than October 31 of the calendar year in which the Bonus Period ends, the Company shall pay the Bonus Payment to Participants who are eligible to receive Bonus Payments, including the individuals set forth on Exhibit A who are so eligible, for each Bonus Period as described in Section 3.1(b).

5

(b) Any Bonus Payment shall be paid in cash and in a single lump sum payment on the applicable Payment Date.

(c) Amounts hereunder shall be reduced by all applicable withholdings, including for federal, state and local taxes.

SECTION 6 – RIGHT TO INTERPRET PLAN; TERMS AND CONDITIONS; AMENDMENT AND TERMINATION.

6.1 Exclusive Discretion. The Plan Administrator shall have the exclusive discretion and authority to establish rules, forms, and procedures for the administration of the Plan and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition, computation or administration arising in connection with the operation of the Plan, including, but not limited to, the eligibility to participate in the Plan and amount of benefits paid under the Plan. The rules, interpretations, computations and other actions of the Plan Administrator shall be binding and conclusive on all persons.

6.2 Amendment or Termination. The Board reserves the right to amend or terminate the Plan or the benefits provided hereunder at any time; provided, however, that no amendment or termination will occur that adversely affects the rights under the Plan of any Participant without the written consent of the SenDEC Representative, and if a Key Participant is affected, then with the written consent of that Key Participant as well. Unless otherwise required by law, no approval of the shareholders of the Company shall be required for any amendment or termination.

6.3 No Implied Employment Contract. The Plan shall not be deemed (i) to give any employee or other person any right to be retained in the employ of the Company or SenDEC, or (ii) to interfere with the right of the Company or SenDEC to discharge any employee or other person at any time, with or without cause, which right is hereby reserved.

6.4 Legal Construction. This Plan shall be governed by and construed under the laws of the State of New York (without regard to principles of conflict of laws). The Plan is intended to be a “bonus program” as defined under U.S. Department of Labor regulation section 2510.3-2(c) and shall be construed and interpreted accordingly.

6.5 Plan Benefits Unfunded. The liability of the Company to pay any amount to any Participant is based solely on the contractual obligations created by the Plan. The Plan constitutes a mere promise by the Company to pay benefits in the future as determined in the sole discretion of the Plan Administrator. The interest of a Participant in benefits payable under the Plan is an unsecured claim against the general assets of the Company. No Participant has any interest in any fund or in any specific asset of the Company by reason of any amounts credited or deemed to be credited hereunder. Accordingly, Plan benefits are not secured by any trust, pledge, lien or encumbrance on any property of the Company or on the assets of any benefit trust. The Company intends that the Plan be unfunded for tax purposes and for purposes of Title I of ERISA, if applicable.

SECTION 7 – SECTION 409A

7.1 Construction. To the extent that payments or benefits under this Plan are subject to (and not exempt from) Section 409A of the Internal Revenue Code of 1986, as amended and the regulations and other guidance promulgated thereunder (“Section 409A”), then such amounts are intended to comply with Section 409A as amounts payable on a “specified time” in accordance with Treas. Reg. Section 1.409A-3(i)(1)(i), in each case, so none of the Bonus Payments to be provided hereunder will be subject to the additional tax imposed under Section 409A. Any ambiguities or ambiguous terms herein will be interpreted to be exempt from or so comply with the requirements of Section 409A. The Company and each Participant will work together in good faith to consider either (i) amendments to this Plan; or (ii) revisions to the Plan with respect to the payment of any Bonus Payments, which are necessary or appropriate to avoid imposition of any additional tax or income recognition prior to the actual payment to the Participant under Section 409A. Notwithstanding anything in the Plan to the contrary, the Company reserves the right, in its sole discretion and without the consent of any Participant, to take such reasonable actions and make any amendments to the Plan as it deems necessary, advisable or desirable to comply with Section 409A or to otherwise avoid income recognition under Section 409A or imposition of any additional tax prior to the actual payment of any Bonus Amounts.

7

CONFLICT WITH NEW YORK LAW, NEW YORK LAW SHALL TAKE PRECEDENCE. THE DECISION OF THE ARBITRATOR SHALL BE FINAL, CONCLUSIVE, AND BINDING ON THE PARTIES TO THE ARBITRATION.
