Welfare Plans and the Retirement Plans are sometimes referred to collectively herein as the

generally with respect to other similarly situated executives employed by the Company.

5.6. Expense Reimbursement. During and in respect of the Employment Period, the
Executive shall be entitled to receive reimbursement for reasonable business expenses incurred by

any other similar type of insurance, that provides coverage for the Executive’s acts or omissions
undertaken during the course and scope of his employment

as chief executive officer, the Executive shall remain a member of the Board unless mutually agreed
that he shall resign or in the event Executive is not able to serve for any reason.

6.1. Termination Due to Death. In the event of the Executive’s death, the Company
will terminate the Executive’s employment hereunder and the Executive’s estate or his legal
representative, as the case may be, shall be entitled to: (a) any Base Salary earned but unpaid as
of the date of death; (b) a pro-rata payment of the portion of the discretionary Incentive Bonus
that would have been earned for such year (determined at the end of the fiscal year in which such
termination occurs) multiplied by a fraction, the numerator of which is the number of days
transpired in the calendar year up to and including the date on which the Executive is terminated
by the Company due to death, and the denominator of which is 365, such payment shall be made at the
time when bonus payments are paid to other senior executives in accordance with the Company’s
normal payroll procedures; and (c) any other payments and/or benefits which the Executive or the
Executive’s legal representative is entitled to receive under any of the Benefit Plans or otherwise
in accordance with the terms of such plan or arrangement.

6.2. Termination Due to the Executive’s Disability. If Executive’s condition meets
the definition of Disability above, the Company may terminate Executive’s employment upon written
notice. If terminated by the Company as herein provided, the Company shall pay to Executive:

(a) any Base Salary earned but unpaid as of the date of the Executive’s termination due to
Disability and for 180 days after said termination as salary continuation;

(b) a pro-rata payment, for the year of termination equal to the Incentive Bonus that would
have been earned for such year (determined at the end of the fiscal year in which such termination
occurs) multiplied by a fraction, the numerator of which is the number of days transpired in the
calendar year up to and including the date on which the Executive is terminated by the Company due
to Disability, and the denominator of which is 365, such payment shall be made at the time when
bonus payments are paid to other senior executives in accordance with the Company’s normal payroll
procedures; and

(c) any other payments and/or benefits which the Executive or the Executive’s legal
representative is entitled to receive under any of the Benefit Plans or otherwise in accordance
with the terms of such plan or arrangement.

Notwithstanding the foregoing, if, in the good faith determination of the Board, the Executive
is suffering from a mental or physical disease or condition that impacts the performance of his
duties in any material respect and it has not yet been determined whether Executive’s condition
meets the definition of Disability, the Company may, in its absolute and sole discretion, suspend
the Executive for a period of up to 180 days (provided that such suspension shall not constitute
Good Reason under Section 1.5 and provided further that during such suspension, the Executive shall
(a) continue to receive his Base Salary in accordance with Section 5.1 and (b) be eligible to
receive the benefits he may be entitled to under the Company’s short-term disability plan, if any).
If the Board does not re-instate the Executive to employment (under the terms and conditions of
this Agreement) by the end of such 180 day period or at any time prior to the end of such period,
the Company may (i) terminate the Executive’s employment without Cause (as provided under Section
6.3) if the Executive’s condition does not meet the definition of Disability at the time of
termination, or (ii) terminate the Executive’s employment due to Disability (as provided under this
Section) if the Executive’s condition meets the definition of Disability at the time of
termination, with the exception of the salary continuation payment.

6.3. Termination by the Company Without Cause or by the Executive for Good Reason. At
any time the Company shall have the right to terminate the Executive’s employment without cause by
providing written notice not less than ninety (90) days prior to the termination date, to the
Executive. The Executive may terminate his employment hereunder with the Company for Good Reason
upon 90 days written notice.

6.3.1. Upon any termination pursuant to this Section 6.3, the Executive shall be entitled to,
upon execution of a general release of claims against the Company and after the expiration of any
applicable rescission or revocation period: (a) Base Salary earned but unpaid as of the date of the
Executive’s termination and (b) any other payments and/or benefits which the Executive is entitled
to receive under any of the Benefit Plans or otherwise in accordance with the terms of such plan or
arrangement. Additionally, the Executive will receive (i) Base Salary in effect at the time of the
termination for a period of twelve (12) months (the “Continuation Period”) following the
termination of the Executive’s employment with the Company, in the manner and at such times as the
Base Salary otherwise would have been payable to the Executive, (ii) continuation of medical and
dental benefits in effect under COBRA as of the date of termination of employment for the
Continuation Period, (iii) a pro-rata payment for the year of termination equal to the
discretionary Incentive Bonus multiplied by a fraction, the numerator of which is the number of
days transpired in the calendar year up to and including the date on which the Executive’s
employment is terminated rounded to the end of the quarter in accordance with 5.2(b), and the
denominator of which is 365, such payment shall be made at the time of termination in accordance
with the Company’s normal payroll procedures; and (iv) all unvested Stock Options scheduled to vest
over a period of twelve (12) months following the date of termination shall immediately vest and be
immediately exercisable. In order to comply with Section 409A of the Internal Revenue Code of 1986,

benefit provided, pursuant to this Section 6.3.1 be accelerated or subject to a further deferral
except as otherwise permitted or required pursuant to regulations or other guidance issued pursuant
to Section 409A of the Code. In addition, Executive does not have any right to make any election
regarding the time or form of any payment due under this Section 6.3.1 or any other provision of
this Agreement

6.4. Termination by the Company for Cause or Termination by the Executive Without
Good Reason. The Executive shall have the right to terminate his employment hereunder without
Good Reason or without any reason at all. The Company may terminate the Executive’s employment
hereunder for Cause. In either such event, the Executive shall be entitled only to: (a) any Base
Salary earned but unpaid through the date of such termination; (b) any other accrued and vested
payments and/or benefits which the Executive is entitled to receive under any of the Benefit Plans.

6.5 Change in Control of the Company

6.5.1 Executive understands and acknowledges that the Company may undergo a Change in Control.
Unless Executive elects to terminate this Agreement pursuant to subparagraph 6.5.3 below, the
Executive hereby acknowledges and agrees that the Executive shall have no right to terminate this
Agreement for a period of one year following the date of a Change in Control and receive the
benefits in Section 6.5.4.

6.5.2 In the event of a pending Change in Control wherein the Company and/or the Executive
have not received written notice at least five (5) business days prior to the anticipated closing
date of a transaction giving rise to the Change in Control from the successor to all or a
substantial portion of the Company’s business and/or assets that such successor is willing as of
the closing to assume and agree to perform the Company’s obligations under this Agreement in the
same manner and to the same extent that the Company is hereby required to perform, then such Change
in Control shall be deemed to be a termination of this Agreement by the Company and Section 6.5.4
hereof will apply.

6.5.3 In any Change in Control situation, Executive may, at his sole discretion, elect to
terminate this Agreement at any time on or after the one-year anniversary of the date of the Change
in Control by providing written notice to the Company and/or a successor to all or a substantial
portion of the Company’s business and/or assets at least ninety (90) days prior to the anticipated
termination date. In such case, or in the event that the Company and/or its successor terminates
the Executive after a Change in Control for any reason, the applicable provisions of Section 6.5.4
hereof will apply.

6.5.4 Upon any termination pursuant to this Section 6.5, the Executive shall be entitled to:
(a) Base Salary earned but unpaid as of the date of the Executive’s termination and (b) any other

or otherwise in accordance with the terms of such plan or arrangement. Additionally, the Executive
will receive (i) the Executive’s Base Salary in effect at the time of the termination for a period
of fifteen (15) months (the “Continuation Period”) following the termination of the Executive’s
employment with the Company, in the manner and at such times as the Base Salary otherwise would
have been payable to the Executive, (ii) continuation of medical and dental benefits under COBRA in
effect as of the date of termination of employment for the Continuation Period, (iii) payment equal
to the discretionary Incentive Bonus earned for such year, such payment shall be made at the time
of termination in accordance with the Company’s normal payroll procedures; and (iv) all of
Executive’s Stock Options in the Company shall immediately vest and become exercisable and all or
any portion of the vested Stock Options may be exercised at any one or more times by the Executive
for a period of three (3) months following termination of Executive’s employment with the Company.

6.5.5 For purposes of applying this Section 6.5 under the circumstances described in Section
6.5.2 above, the effective date of termination will be the closing date of the transaction giving
rise to the Change in Control and all compensation, reimbursements and lump-sum payments due
Executive must be paid in full by the Company at or prior to such closing.

6.6. Certain Other Payments.

6.6.1. In the event that (i) the Executive becomes entitled to any other payments or benefits
from the Company in connection with a Change in Control (collectively, the “Total Payments”) which
constitute an “excess parachute payment” as defined in Section 280G(b) of the Code, and (ii) the
Executive would be subject to an excise tax imposed under Section 4999 of the Code (the “Excise
Tax”), then the Executive may submit all or any portion of the Total Payments to a shareholder vote
for purposes of satisfying Section 280G(b)(5) of the Code (a “Shareholder Vote”).

6.6.2. To the extent that the Executive does not so submit any portion of the Total Payments
to a Shareholder Vote and, if any such portion of the Total Payments would subject Executive to the
Excise Tax, then, such non-submitted portion of the Total Payments and benefits will be reduced to
the extent necessary to eliminate the imposition of the Excise Tax.

7. Successors.

7.1. The Executive. This Agreement is personal to the Executive and, without the prior
express written consent of the Company, shall not be assignable by the Executive, except that the
Executive’s rights to receive any compensation or benefits under this Agreement may be transferred

relations order. This Agreement shall inure to the benefit of and be enforceable by the

5. Compensation and Other Benefits.

5.1. Base Salary. During the Employment Period, the Executive shall receive a base

5.2. Annual Incentive Bonus.

a. In each calendar year during the Employment Period, beginning in calendar year 2009, the
Executive shall be eligible to receive an annual incentive bonus determined annually at the

months following the Employment Period.

5.4. Vacation. The Executive shall be entitled to three (3) weeks of paid vacation
earned ratably over each calendar year during the Employment Period, to be taken at such times as

policies and/or programs maintained by the Company from time to time including, without limitation,
all medical, hospitalization, dental, disability, life, accidental death and dismemberment and
travel accident insurance plans, policies and/or programs (the “Welfare Benefit Plans”). The
Welfare Plans and the Retirement Plans are sometimes referred to collectively herein as the

generally with respect to other similarly situated executives employed by the Company.

5.6. Expense Reimbursement. During and in respect of the Employment Period, the
Executive shall be entitled to receive reimbursement for reasonable business expenses incurred by
the Executive in performing his duties and responsibilities hereunder, including travel,
entertainment, parking, business meetings and professional dues, incurred and substantiated in

any other similar type of insurance, that provides coverage for the Executive’s acts or omissions
undertaken during the course and scope of his employment.

6. Termination.

6.1. Termination Due to Death. In the event of the Executive’s death, the Company
will terminate the Executive’s employment hereunder and the Executive’s estate or his legal
representative, as the case may be, shall be entitled to: (a) any Base Salary earned but unpaid as
of the date of death; (b) a pro-rata payment of the portion of the discretionary Incentive Bonus
that would have been earned for such year (determined at the end of the fiscal year in which such
termination occurs) multiplied by a fraction, the numerator of which is the number of days
transpired in the calendar year up to and including the date on which the Executive is terminated
by the Company due to death, and the denominator of which is 365, such payment shall be made at the
time when bonus payments are paid to other senior executives in accordance with the Company’s
normal payroll procedures; and (c) any other payments and/or benefits which the Executive or the
Executive’s legal representative is entitled to receive under any of the Benefit Plans or otherwise
in accordance with the terms of such plan or arrangement.

6.2. Termination Due to the Executive’s Disability. If Executive’s condition meets
the definition of Disability above, the Company may terminate Executive’s employment upon written
notice. If terminated by the Company as herein provided, the Company shall pay to Executive:

(a) any Base Salary earned but unpaid as of the date of the Executive’s termination due to
Disability and for 180 days after said termination as salary continuation;

(b) a pro-rata payment, for the year of termination equal to the Incentive Bonus that would
have been earned for such year (determined at the end of the fiscal year in which such termination
occurs) multiplied by a fraction, the numerator of which is the number of days transpired in the
calendar year up to and including the date on which the Executive is terminated by the Company due
to Disability, and the denominator of which is 365, such payment shall be made at the time when
bonus payments are paid to other senior executives in accordance with the Company’s normal payroll
procedures; and

(c) any other payments and/or benefits which the Executive or the Executive’s legal
representative is entitled to receive under any of the Benefit Plans or otherwise in accordance
with the terms of such plan or arrangement.

Notwithstanding the foregoing, if, in the good faith determination of the Board, the Executive
is suffering from a mental or physical disease or condition that impacts the performance of his
duties in any material respect and it has not yet been determined whether Executive’s condition
meets the definition of Disability, the Company may, in its absolute and sole discretion, suspend
the Executive for a period of up to 180 days (provided that such suspension shall not constitute
Good Reason under Section 1.5 and provided further that during such suspension, the Executive shall
(a) continue to receive his Base Salary in accordance with Section 5.1 and (b) be eligible to
receive the benefits he may be entitled to under the Company’s short-term disability plan, if any).
If the Board does not re-instate the Executive to employment (under the terms and conditions of
this Agreement) by the end of such 180 day period or at any time prior to the end of such period,
the Company may (i) terminate the Executive’s employment without Cause (as provided under Section
6.3) if the Executive’s condition does not meet the definition of Disability at the time of
termination, or (ii) terminate the Executive’s employment due to Disability (as provided under this
Section) if the Executive’s condition meets the definition of Disability at the time of
termination, with the exception of the salary continuation payment.

6.3. Termination by the Company Without Cause or by the Executive for Good Reason. At
any time the Company shall have the right to terminate the Executive’s employment without cause by
providing written notice not less than ninety (90) days prior to the termination date, to the
Executive. The Executive may terminate his employment hereunder with the Company for Good Reason
upon 90 days written notice.

6.3.1. Upon any termination pursuant to this Section 6.3, the Executive shall be entitled to,
upon execution of a general release of claims against the Company and after the expiration of any
applicable rescission or revocation period: (a) Base Salary earned but unpaid as of the date of the
Executive’s termination and (b) any other payments and/or benefits which the Executive is entitled
to receive under any of the Benefit Plans or otherwise in accordance with the terms of such plan or
arrangement. Additionally, the Executive will receive (i) Base Salary in effect at the time of the
termination for a period of twelve (12) months (the “Continuation Period”) following the
termination of the Executive’s employment with the Company, in the manner and at such times as the
Base Salary otherwise would have been payable to the Executive, (ii) continuation of medical and
dental benefits in effect under COBRA as of the date of termination of employment for the
Continuation Period, (iii) a pro-rata payment for the year of termination equal to the
discretionary Incentive Bonus multiplied by a fraction, the numerator of which is the number of
days transpired in the calendar year up to and including the date on which the Executive’s
employment is terminated rounded to the end of the quarter in accordance with 5.2(b), and the
denominator of which is 365, such payment shall be made at the time of termination in accordance
with the Company’s normal payroll procedures; and (iv) all unvested Stock Options scheduled to vest
over a period of twelve (12) months following the date of termination shall immediately vest and be
immediately exercisable. In order to comply with Section 409A of the Internal Revenue Code of 1986,
as amended (the “Code”), under no circumstances may the time or schedule of any payment made, or
benefit provided, pursuant to this Section 6.3.1 be accelerated or subject to a further deferral
except as otherwise permitted or required pursuant to regulations or other guidance issued pursuant
to Section 409A of the Code. In addition, Executive does not have any right to make any election
regarding the time or form of any payment due under this Section 6.3.1 or any other provision of
this Agreement.

6.4. Termination by the Company for Cause or Termination by the Executive Without
Good Reason. The Executive shall have the right to terminate his employment hereunder without
Good Reason or without any reason at all. The Company may terminate the Executive’s employment
hereunder for Cause. In either such event, the Executive shall be entitled only to: (a) any Base
Salary earned but unpaid through the date of such termination; (b) any other accrued and vested
payments and/or benefits which the Executive is entitled to receive under any of the Benefit Plans.

6.5 Change in Control of the Company

6.5.1 Executive understands and acknowledges that the Company may undergo a Change in Control.
Unless Executive elects to terminate this Agreement pursuant to subparagraph 6.5.3 below, the
Executive hereby acknowledges and agrees that the Executive shall have no right to terminate this
Agreement for a period of one year following the date of a Change in Control and receive the
benefits in Section 6.5.4.

6.5.2 In the event of a pending Change in Control wherein the Company and/or the Executive
have not received written notice at least five (5) business days prior to the anticipated closing
date of a transaction giving rise to the Change in Control from the successor to all or a
substantial portion of the Company’s business and/or assets that such successor is willing as of
the closing to assume and agree to perform the Company’s obligations under this Agreement in the
same manner and to the same extent that the Company is hereby required to perform, then such Change
in Control shall be deemed to be a termination of this Agreement by the Company and Section 6.5.4
hereof will apply.

6.5.3 In any Change in Control situation, Executive may, at his sole discretion, elect to
terminate this Agreement at any time on or after the one-year anniversary of the date of the Change
in Control by providing written notice to the Company and/or a successor to all or a substantial
portion of the Company’s business and/or assets at least ninety (90) days prior to the anticipated
termination date. In such case, or in the event that the Company and/or its successor terminates
the Executive after a Change in Control for any reason, the applicable provisions of Section 6.5.4
hereof will apply.

6.5.4 Upon any termination pursuant to this Section 6.5, the Executive shall be entitled to:
(a) Base Salary earned but unpaid as of the date of the Executive’s termination and (b) any other
payments and/or benefits which the Executive is entitled to receive under any of the Benefit Plans
or otherwise in accordance with the terms of such plan or arrangement. Additionally, the Executive
will receive (i) the Executive’s Base Salary in effect at the time of the termination for a period
of fifteen (15) months (the “Continuation Period”) following the termination of the Executive’s
employment with the Company, in the manner and at such times as the Base Salary otherwise would
have been payable to the Executive, (ii) continuation of medical and dental benefits under COBRA in
effect as of the date of termination of employment for the Continuation Period, (iii) payment equal
to the discretionary Incentive Bonus earned for such year, such payment shall be made at the time
of termination in accordance with the Company’s normal payroll procedures; and (iv) all of
Executive’s Stock Options in the Company shall immediately vest and become exercisable and all or
any portion of the vested Stock Options may be exercised at any one or more times by the Executive
for a period of three (3) months following termination of Executive’s employment with the Company.

6.5.5 For purposes of applying this Section 6.5 under the circumstances described in Section
6.5.2 above, the effective date of termination will be the closing date of the transaction giving
rise to the Change in Control and all compensation, reimbursements and lump-sum payments due
Executive must be paid in full by the Company at or prior to such closing.

6.6. Certain Other Payments.

6.6.1. In the event that (i) the Executive becomes entitled to any other payments or benefits
from the Company in connection with a Change in Control (collectively, the “Total Payments”) which
constitute an “excess parachute payment” as defined in Section 280G(b) of the Code, and (ii) the
Executive would be subject to an excise tax imposed under Section 4999 of the Code (the “Excise
Tax”), then the Executive may submit all or any portion of the Total Payments to a shareholder vote
for purposes of satisfying Section 280G(b)(5) of the Code (a “Shareholder Vote”).

6.6.2. To the extent that the Executive does not so submit any portion of the Total Payments
to a Shareholder Vote and, if any such portion of the Total Payments would subject Executive to the
Excise Tax, then, such non-submitted portion of the Total Payments and benefits will be reduced to
the extent necessary to eliminate the imposition of the Excise Tax.

7. Successors.

7.1. The Executive. This Agreement is personal to the Executive and, without the prior
express written consent of the Company, shall not be assignable by the Executive, except that the
Executive’s rights to receive any compensation or benefits under this Agreement may be transferred
or disposed of pursuant to testamentary disposition, intestate succession or pursuant to a domestic
relations order. This Agreement shall inure to the benefit of and be enforceable by the
Executive’s heirs, beneficiaries and/or legal representatives.

licensee or other business entity and the Company.

bound by this Agreement and furnish each such person or entity with a copy of this Agreement or
relevant portions thereof.

9.4. Injunctive Relief. The Executive acknowledges and agrees that the Company will
have no adequate remedy at law, and would be irreparably harmed, if the Executive breaches or
threatens to breach any of the provisions of this Section 9 of this Agreement. The Executive agrees

that the potential restrictions on the Executive’s future employment imposed by this Section 9 be
reasonable in both duration and geographic scope and in all other respects. If for any reason any
court of competent jurisdiction shall find any provisions of this Section 9 unreasonable in
duration or geographic scope or otherwise, the Executive and the Company agree that the
restrictions and prohibitions contained herein shall be effective to the fullest extent allowed
under applicable law in such jurisdiction.

threatened to be made a party to any action, suit or proceeding, whether civil, criminal,
administrative or investigative (a “Proceeding”), by reason of the fact that he is or was a
director or officer of the Company, whether or not the basis of such Proceeding is alleged action
in an official capacity as a director, officer, employee or agent while serving as a director,
officer, employee or agent, he shall be indemnified and held harmless by the Company (unless the
Executive’s actions or omissions constitute gross negligence or willful misconduct) to the fullest
extent authorized by law, as the same exists or may hereafter be amended, against all costs and
expenses incurred or suffered by the Executive in connection therewith, and such indemnification
shall continue as to the Executive even if the Executive has ceased to be an officer, director or
agent, or is no longer employed by the Company and shall inure to the benefit of his heirs,
