payment would have been payable had Executive continued to be employed by the
Company.

	 	b)	 	As of November 30, 2007, the Executive is currently the holder
of 208,168 outstanding stock options of which, upon the Succession Date,
133,332 will be vested. The vesting of the unvested stock options on the
Succession Date shall be as follows:

	 	(1)	 	The 58,334 options which, in
accordance with the terms of the Company’s August 1, 2005, grant
to the Executive under the Nonqualified Stock Option Agreement,
dated as of July 22, 2005 (the “July 2005 Agreement”), will not
become vested until August 1, 2008, shall, notwithstanding
Section 5 of the July 2005 Agreement, become fully vested
immediately upon the Succession Date.

	 	(2)	 	16,667 of the 33,334 options

become fully vested immediately upon the Succession Date for
each full month of the Term ending prior to the Succession Date,
provided, however, that in the event that the Succession Date
occurs on or prior to May 1, 2008, at least 10,002 of such
options will become fully vested on such Succession Date;
provided, further, that no such option shall in any event be
exercisable sooner than six months after the date of grant. The
remaining options shall be cancelled in accordance with the
October 2007 Grant.

	 	c)	 	For a period of 12 months commencing immediately upon the
Succession Date, the Company shall pay on behalf of the Executive the insurance
premiums associated with the continuation pursuant to COBRA of the Executive’s
medical insurance coverage under all of the Company’s medical plans covering
the senior executive officers of the Company. All payments to be made pursuant
to this Section 10(b) shall be subject to appropriate withholding for federal,
state and other applicable taxes, to the extent required by law.

	 	11.	 	Termination For Cause. The Company may terminate the employment of the
Executive under this Agreement in the event that the Board determines that the
Executive (a) has materially and substantially breached his obligations under Section
8, 9, or 14 of this Agreement, provided that the employment of the Executive shall not
be terminated under this clause (a) unless the Executive is given notice in writing
that the conduct in question constitutes grounds for termination under this Section 11
and the Executive is allowed at least thirty (30) days to remedy the breach, (b) has
been convicted of a felony constituting a crime of moral turpitude (whether or not in
conjunction with the performance by the Executive of his duties under this Agreement),
or (c) has through willful misconduct or gross negligence engaged in an act or course
of conduct that causes material injury to the Company (or any affiliate or subsidiary
of the Company). If the employment of the Executive under this Agreement is terminated
under this Section 11, the Board shall give written notice to the Executive specifying
the cause of such action. Upon a termination of employment under this Section 11, the
Company shall be relieved of all further obligations under this Agreement, other than
the payment of any accrued and unpaid Base Salary through the date of termination and
any expenses for which the Executive is entitled to be reimbursed pursuant to Section
5. Notwithstanding such termination of employment, the Executive shall continue to be
bound by the provisions of Sections 8, 9, and 14.

	 	12.	 	Termination Without Cause.

	 	a)	 	If, prior to the Succession Date, the employment of the
Executive is terminated (i) by the Company other than for Cause or as provided
in Section 13, or (ii) by resignation of the Executive because the
responsibilities and duties of the Executive are, other than for Cause,
materially diminished or changed by the Company in a manner that materially
impairs the Executive’s ability to function as the Chief Executive Officer of
the Company (provided that such diminution or change is not cured by the
Company within 30 days after receiving notice thereof from the Executive), the
Executive shall be entitled to receive, no later than 60 days following such
termination, a Severance Payment (as defined herein).

	 	b)	 	For purposes hereof, “Severance Payment” shall mean: (i) upon
termination effective date, or upon or after any Change in Control, a lump sum
amount equal to the Executive’s annual Base Salary at the time of such
termination.

	 	c)	 	Termination of employment under this Section 12 shall not
terminate the Executive’s obligations under Sections 8, 9 and 14.

	 	13.	 	Death or Disability of the Executive. In the event that the Executive,
during the period while employed under this Agreement, shall die or, as a result of the
Executive’s incapacity due to injury or physical or mental illness, the Executive shall
have been unable to perform the Executive’s duties with the Company for a period of
three consecutive months, or for four months out of any six consecutive months, the
Company may terminate this Agreement and be relieved of all further obligations
hereunder, other than the payment of any accrued and unpaid Base Salary through the
date of termination and any expenses for which the Executive is entitled to be
reimbursed pursuant to Section 5. Termination of employment under this Section 13 by
reason of disability shall not terminate the Executive’s obligations under Section 8, 9
and 14.

	 	14.	 	Non-Competition. The Executive hereby agrees that, during the Term and
for a period of eighteen (18) months following the termination of his employment under
this Agreement, he will not, directly or indirectly and in any way, (a) own, manage,
operate, control, be employed by, participate in, or be connected in any manner with
the ownership, management, operation or control of any business competing with the
business of the Company, (b) interfere with, solicit on behalf of another or attempt to
entice away from the Company (or any affiliate or subsidiary of the Company) (i) any
project, financing or customer that the Company (or any affiliate or subsidiary of the
Company) has under contract (including unfulfilled purchase orders), or any letter of
supply or other supplier contract or arrangement entered into by the Company (or any
affiliate or subsidiary of the Company), and all extensions, renewals and
resolicitations of such contracts or arrangements, (ii) any contract, agreement or
arrangement that the Company (or any affiliate or subsidiary of the Company) is
actively negotiating with any other party, or (iii) any prospective business
opportunity that the Company (or any affiliate or subsidiary of the Company) has
identified, or (c) for himself or another, hire, attempt to hire, or assist in or
facilitate in any way the hiring of any employee of the Company (or any affiliate or
subsidiary of the Company), or any employee of any person, firm or other entity, the
employees of which the Company (or any affiliate or subsidiary of the Company) has
agreed not to hire or endeavor to hire. The effective time of the limitations imposed
by this Section 13 shall be extended for the period of time equal to any period of time
during which the Executive acts in circumstances that a court of competent jurisdiction
finds to have violated the terms of this Section 14.

Because of the Executive’s knowledge of the Company’s business, in the event of the
Executive’s actual or threatened breach of the provisions of this Section 14, the
Company shall be entitled to, and the Executive hereby consents to, an injunction
restraining the Executive from any of the foregoing. However, nothing herein shall be
construed as prohibiting the Company from pursuing any other available remedies for such
breach or threatened breach, including the recovery of damages from the Executive. The
Executive agrees that the provisions of this Section 14 are necessary and reasonable to
protect the Company in the conduct of its business. If any restriction contained in
this Section 14 shall be deemed to be invalid or unenforceable by reason of the extent,
duration of geographic scope thereof, then the Company shall have the right to reduce
such extent, duration, geographic scope of other provisions thereof, and in their
reduced form such restrictions shall then be enforceable in the manner contemplated
hereby.

	 	15.	 	Capacity. The Executive represents and warrants to the Company that he
is not now under any obligation, of a contractual nature or otherwise, to any person,
firm, corporation, association or other entity that is inconsistent or in conflict with
this Agreement or which would prevent, limit or impair in any way the performance by
him of his obligations hereunder.

	 	16.	 	Withholding. The Executive acknowledges that salary and all other
compensation payable under this Agreement shall be subject to withholding for income
and other applicable taxes to the extent required by law, as determined by the Company
in its reasonable judgment.

	 	17.	 	Indemnification. To the greatest extent permitted by applicable law,
and in a manner consistent with any procedures required by applicable law, the
Corporation shall, during and following the termination of the Executive’s employment
by the Company, indemnify and hold the Executive harmless from and against any
liability (including, without limitation, reasonable attorneys’ fees) incurred by the
Executive in any claim, action, suit, or proceeding instituted or brought against the
Executive as a result of or arising out of service by the Executive as an officer or
director of the Company, or of any other corporation or other entity at the request or
direction of the Company, except to the extent that such liability is the result of the
criminal action or willful misconduct on the part of the Executive.

	 	18.	 	Waiver. No act, delay, omission or course of dealing on the part of
any party hereto in exercising any right, power or remedy hereunder shall operate as,
or be construed as, a waiver thereof or otherwise prejudice such party’s rights, powers
and remedies under this Agreement.

	 	19.	 	Notice. Any and all notices referred to herein shall be sufficient if
furnished in writing and delivered by hand, by facsimile transmission or by overnight
delivery service maintaining records of receipt, to the respective parties at the

	 	26.	 	Headings; Construction. Headings contained in this Agreement are
