as its President and Chief Executive Officer;

to provide for, among other things, (i) the extension of the Employment Term (as
defined below) until June 30, 2009; (ii) an evergreen provision which provides

WHEREAS, the Company wishes to continue to employ the Executive as the President
and Chief Executive Officer of the Company under the terms and conditions set

WHEREAS, the Executive wishes to accept such continued employment under those
terms and conditions;

NOW, THEREFORE, in consideration of the provisions and mutual covenants
contained in this Agreement and for other good and valuable consideration, the
Company and the Executive (each a “Party” and together the “Parties”) agree as
follows:

 

1. Term of Employment.

The Company agrees to employ the Executive, and the Executive agrees to serve,
on the terms and conditions of this Agreement, for a period commencing as of
October 18, 2007 (the “Effective Date”) and ending on June 30, 2009, or such
shorter period as may be provided for herein, and such term of employment shall
be automatically extended by an additional one-year term in the event that
(i) the Company fails to provide written notice of non-renewal of the Agreement
to the Executive in accordance with Section 24 not later than 180 days prior to
the expiration of the then current employment term (each, an “Extension”) and
(ii) the Executive fails to provide written notice of non-renewal of the
Agreement to the Chairman of the Compensation Committee (defined below) in
accordance with Section 24 not later than 90 days prior to the commencement of
any Extension. The employment term described above, including any Extension, is
hereinafter referred to as the “Employment Term”.

--------------------------------------------------------------------------------

2. Position, Duties, Responsibilities.

During the Employment Term, the Executive shall serve as President and Chief
Executive Officer of the Company. In such capacity, the Executive shall report
to the Board of Directors of the Company (the “Board of Directors”) and shall
perform such duties and have such responsibilities of an executive nature as are
set forth in the Company’s Amended and Restated By-Laws, as amended from time to
time (the “By-Laws”), and as are customarily performed by a person holding such
office, it being recognized that the Executive’s duties and responsibilities,
consistent with his titles hereunder, may be changed by the Board of Directors
from time to time. The Executive shall devote his full business time and
attention to the performance of his duties under this Agreement; provided,
however, that the Executive shall be permitted to serve as a director on up to
two boards of directors in addition to the Board of Directors. In addition,
during the Employment Term, the Executive shall serve without additional
compensation as Chairman of the Board of Directors and a director of the Company
and on any committees of the Board of Directors, if requested, subject to the
terms of the By-Laws and to the approval of the stockholders of the Company to
the extent required by applicable law and the By-Laws.

 

3. Base Salary.

During the Employment Term and effective as of the Effective Date, the Executive
shall be paid an annual base salary of $460,000 (“Salary”), subject to
deductions for social security, state payroll and unemployment and all other
legally required or authorized deductions and withholding. The Executive’s
Salary shall be payable in accordance with the Company’s standard payroll
practice. The Compensation Committee (as defined below) shall review and
establish the Salary at least on an annual basis on October 18 of each year
during the Employment Term.

 

4. Stock Options.

On the Effective Date, the Executive shall be granted a stock option (the
“Option”) to purchase 24,000 shares of common stock, par value $.001 per share,
of the Company (the “Common Stock”), under the Company’s 2007 Stock Incentive
Plan (the “2007 Plan”). The exercise price for the Option shall be the closing
sale price of the Common Stock on the date of grant, which date shall be the
Effective Date, as specified in the 2007 Plan. The Option shall, to the maximum
extent permissible under Section 422 of the Internal Revenue Code of 1986, as
amended, constitute incentive stock options, with any balance of the Option to
be treated as non-statutory stock options. The Option shall vest in 48 equal
monthly installments on each monthly anniversary of the date of grant. Once
exercisable, the Option shall remain exercisable for a period of ten (10) years
from the date of grant. Notwithstanding the foregoing, the Option shall become
immediately exercisable in the event of a Change of Control of the Company or
the termination of the Executive’s employment without cause pursuant to
Section 14. For purposes of this Agreement, a “Change of Control of the Company”
shall be deemed to have occurred only upon (a) any merger or consolidation of
the Company with or into another entity as a result of which the Common Stock is
converted into or exchanged for the right to receive cash, securities or other
property or (b) any exchange of all or substantially all shares of the Company
for cash, securities or other property pursuant to a statutory share exchange
transaction.

--------------------------------------------------------------------------------

5. Annual Bonus.

Commencing with the Company’s fiscal year ended December 31, 2007, after the
completion of the Company’s fiscal year and as soon as the Company’s financial
information required to be included in its Annual Report on Form 10-K for such
fiscal year is available, but in no event later than 90 days after the end of
such fiscal year, the Executive shall be entitled to receive an annual bonus
(the “Annual Bonus”) consisting of a cash bonus of up to 36% of the Salary as
then in effect for such fiscal year provided that the Executive satisfies
agreed-upon financial and other performance goals each as contained in an annual
incentive plan for the Executive as established in good faith by the Joint
Compensation and Options Committee of the Board of Directors (the “Compensation
Committee”) after consultation with the Executive on an annual basis (the
“Incentive Plan”); provided, however, that the Compensation Committee, in its
reasonable discretion, shall determine whether the Executive has satisfied such
goals. In the event that the Executive is entitled to the Annual Bonus, then the
Executive shall be paid the Annual Bonus prior to the Company filing its Annual
Report on Form 10-K for such fiscal year.

 

6. Cash Payment Upon Change of Control.

(a) Upon the consummation of a Change of Control of the Company, and subject to
the provisions of this Section 6, the Executive shall be entitled to receive a
cash payment equal to a percentage of the Total Deal Consideration (as defined
below) in accordance with Schedule I attached hereto (the “Applicable
Percentage”).

(b) For purposes of this Agreement, “Total Deal Consideration” shall mean the
gross value of all cash, securities and other property actually paid directly or
indirectly by an acquirer in a transaction constituting a Change of Control of
the Company (including without limitation all amounts paid or distributed by the
Company to the holders of its capital stock in anticipation of the transaction,
but excluding all amounts paid, distributed or issued to the holders of
convertible securities, options, warrants, stock appreciation rights or similar
rights or securities of the Company in connection with such transaction). Total
Deal Consideration shall also be deemed to include the aggregate principal
amount of any indebtedness for borrowed money assumed (net of cash on hand) or
extinguished in connection with such transaction. The value of any securities
(whether debt or equity) or other property shall be determined as follows:
(i) the value of securities for which there is an established public market will
be equal to the closing market price on the day of closing of such transaction
and (ii) the value of securities that have no established public market, and the
value of consideration that consists of other property, shall be the fair market
value thereof as determined in good faith by the Board of Directors of the
Company.

(c) For purposes of this Section 6 only, “Change of Control of the Company”
shall not include (A) a recapitalization of the Company, (B) a merger effected
exclusively to change the domicile of the Company and (C) any “management
buy-out” or other similar transaction in which the Company is acquired by an
entity or group in which the Executive is a participant or equity holder.

 

- 3 -

--------------------------------------------------------------------------------

(d) Nothing in this Agreement shall be deemed to obligate the Company to
undertake any action that would result in the receipt by the Executive of a cash
payment under this Section 6.

(e) If any part of the consideration payable in a transaction constituting a
Change of Control of the Company consists of contingent payments to be
calculated by reference to uncertain future occurrences, such as future
financial or business performance, then the Applicable Percentage of such
consideration that is actually paid shall not be payable to the Executive in
accordance with Schedule I until the earlier of (A) the receipt of such
consideration by the former holders of the Company’s capital stock and (B) the
time that the amount of such consideration can be determined.

(f) If any part of the consideration payable in a transaction constituting a
Change of Control of the Company is withheld or placed into escrow for some
period of time after the closing of such transaction, then the Applicable
Percentage of such consideration shall not be payable to the Executive in
accordance with Schedule I until and to the extent such consideration is
received by the former holders of the Company’s capital stock.

(g) For purposes of determining the Total Deal Consideration and the
corresponding Applicable Percentage, the value of any contingent payments or any
escrowed or withheld amounts shall be determined in good faith by the Board of
Directors at the time of the consummation of the transaction constituting a
Change of Control of the Company.

 

7. Employee Benefits.

(a) Benefit Programs.

(i) During the Employment Term, the Company shall provide the Executive and
eligible family members with medical, dental, and disability insurance and such
other benefits and perquisites as are provided in the Company’s applicable plans
and programs to its employees generally; provided, that the Executive meets the
qualifications therefor (“Benefits”).

(ii) Notwithstanding the provisions of Section 7(a)(i), the Company shall
reimburse the Executive on a monthly basis for the amounts paid by the Executive
in connection with certain health coverage obtained through the Executive’s
former employer (the “Outside Health Insurance”), net of all taxes and required
deductions; provided, however, that during the term of the Executive’s Outside
Health Insurance, the Executive shall not be entitled to any of the Benefits to
the extent covered by the Executive’s Outside Health Insurance.

(b) Vacation.

During the Employment Term, the Executive shall be entitled to four weeks of
paid vacation per year; provided, however, that any vacation time not taken
during the Employment Term shall be forfeited. The Executive shall also be
entitled to all paid holidays given by the Company to its officers and
employees.

 

- 4 -

--------------------------------------------------------------------------------

(c) Car Expenses.

The Company will provide a monthly automobile allowance of $1,500.

 

8. Representations and Warranties of the Executive.

The Executive represents and warrants to the Company that the Executive is under
no contractual or other restriction or obligation which is inconsistent with the
execution of this Agreement, the performance of his duties hereunder, or the
other rights of the Company hereunder.

 

9. Non-Competition: Non-Solicitation.

In view of the unique and valuable services it is expected Executive will render
to the Company, Executive’s knowledge of the customers, trade secrets, and other
proprietary information relating to the business of the Company and its
customers and suppliers and similar knowledge regarding the Company it is
expected Executive will obtain, and in consideration of the compensation to be
received hereunder, Executive agrees that he will not, during the period he is
employed by the Company under this Agreement or otherwise, and for a period of
one year after he ceases to be employed by the Company under this Agreement or
otherwise, compete with or be engaged in, or Participate In (as defined below)
any other business or organization (which shall not include a university,
hospital, or other non-profit organization) which during such one year period is
or as a result of the Executive’s engagement or participation would become
competitive with the Company’s business of designing, developing, manufacturing,
marketing and selling septal repair devices or other medical devices being
designed, developed, manufactured, marketed or sold by the Company up to the
time of such cessation; provided, however, that the provisions of this Section 9
shall not be deemed breached merely because the Executive owns less than 1% of
the outstanding capital stock of a corporation, if, at the time of its
acquisition by the Executive such stock is listed on a national securities
exchange. The term “Participate In” shall mean: “directly or indirectly, for his
own benefit or for, with or through any other person (including the Executive’s
immediate family), firm or corporation, own, manage, operate, control, loan
money to, or participate in the ownership, management, operation or control of,
or be connected as a director, officer, employee, partner, consultant, agent,
independent contractor, or otherwise with, or acquiesce in the use of his name
in.”

The Executive will not, directly or indirectly, solicit or interfere with, or
endeavor to entice away from the Company any of its suppliers, customers or
employees within a period of one year after the date of termination of the
Executive’s employment (the “Termination Date”). The Executive will not directly
or indirectly employ any person who was an employee of the Company within a
period of one year after such person leaves the employ of the Company.

If any restriction contained in this Section 9 shall be deemed to be invalid,
illegal, or unenforceable by reason of the extent, duration or geographical
scope thereof, or otherwise, then the court making such determination shall have
the right to reduce such extent, duration, geographical scope or other
provisions hereof, and in its reduced form such restriction shall then be
enforceable in the manner contemplated hereby.

--------------------------------------------------------------------------------

10. Intellectual Property Rights.

Any interest in patents, patent applications, inventions, technological
innovations, copyrights, copyrightable works, developments, discoveries, designs
and processes which the Executive during the period he is employed by the
Company under this Agreement or otherwise may acquire, conceive of or develop,
either alone or in conjunction with others, utilizing the time, material,
facilities or information of the Company (“Inventions”) shall belong to the
Company; as soon as the Executive owns, conceives of, or develops any Invention,
he agrees immediately to communicate such fact in writing to the Board of
Directors, and without further compensation, but at the Company’s expense,
forthwith upon request of the Company, the Executive shall execute all such
assignments and other documents (including applications for patents, copyrights,
trademarks, and assignments thereof) and take all such other action as the
Company may reasonably request in order (a) to vest in the Company all of the
Executive’s right, title and interest in and to such Inventions, free and clear
of liens, mortgages, security interests, pledges, charges and encumbrances and
(b), if patentable or copyrightable, to obtain patents or copyrights (including
extensions and renewals) therefor in any and all countries in such name as the
Company shall determine.

 

11. Nondisclosure.

The Employee Nondisclosure and Secrecy Agreement dated as of September 21, 2000
between the Company and the Executive shall remain in full force and effect.

 

12. Injunctive Relief.

Because a breach of the provisions of any of Section 9, Section 10 and
Section 11 could not adequately be compensated by money damages, the Company
shall be entitled, in addition to any other right and remedy available to it, to
an injunction restraining such breach or a threatened breach, and in either case
no bond or other security shall be required in connection therewith. The
Executive agrees that the provisions of each of Section 9, Section 10 and
Section 11 are necessary and reasonable to protect the Company in the conduct of
its business.

 

13. Termination of the Executive Upon Death or Disability.

(a) The term of the Executive’s employment shall terminate automatically upon

or Disability, then the Executive, his guardian or his estate, as applicable,
shall be entitled to:
