         2.       Employment.

         (a)      Subject to the terms and conditions of this Agreement,
Employee is hereby employed by the Company to serve as its President and Chief
Executive Officer. Employee accepts such employment, and agrees to discharge all
of the duties normally associated with said positions, to faithfully and to the
best of his abilities perform such other services consistent with his position
as a senior executive officer as may from time to time be assigned to him by the

and attention to such services. Employee shall do and perform all services,
acts, or things necessary or advisable to manage and conduct the business of the
Company, subject always to the policies set by the Board of Directors of the
Company. Employee shall have full authority to take all actions necessary for
the day-to-day operation of the Company, to formulate corporate policy, and to
administer corporate business in all respects. The authority of Employee
includes the power to employ and discharge corporate personnel (subject to any
restrictions on such actions to which the Company is subject by way of contract,
agreement or otherwise), except for members of the Board of Directors of the
Company, and to engage consultants on behalf of the Company.

         (b)      Notwithstanding the terms of subsection (a) above, Employee
may serve on the boards of directors of other companies, and in civic, cultural,
philanthropic and professional organizations, so long as such service does not
detract from the performance of Employee's duties hereunder. At all times during
which Employee remains President and Chief Executive Officer of the Company,
Employee shall serve as a member of the Company's Board of Directors and, at the
request of the Company's Board of Directors, as an officer or director of any
Company affiliate, in each case without additional remuneration therefor.

         3.       Compensation and Benefits.

         3.1      Base Salary. During the term of Employee's employment
hereunder, the Company shall pay Employee a salary at the annual rate of
$250,000 or such greater amount as the Company's Board of Directors may from
time to time establish pursuant to the terms hereof (the "Base Salary"). Such
Base Salary shall be reviewed annually and may be increased, but not decreased,
by the Board of Directors in its sole discretion. The Base Salary shall be
payable in accordance with the Company's customary payroll practices for its
senior management personnel.

         3.2      Bonus.

         (a)      For each fiscal year of the Company ending during the
Employment Term (as hereinafter defined), Employee shall receive a cash bonus
(the "Base Bonus") in an amount equal to:
<PAGE>   4
                  (i)      once the Company satisfies the financial covenants to
                           be established pursuant to Section 6.15 of the
                           Appaloosa Agreement (the "Financial Covenants"), 50%
                           of the Base Salary; and

                  (ii)     once the Company achieves certain specified target
                           performance levels (the "Target Performance Levels")
                           set forth in the Annual Plan, 60% of the Base Salary
                           (it being acknowledged and agreed that the sum of
                           subparagraphs (i) and (ii) of this Section 3.2 shall
                           not exceed 60% of the Base Salary in the aggregate);
                           provided, however, that if the Company fails to
                           establish Target Performance Levels, Employee shall
                           be entitled to a cash bonus equal to 60% of Base
                           Salary if the Company satisfies the Financial
                           Covenants applicable to such fiscal year.

Notwithstanding the foregoing, even if the Company fails to achieve the Target
Performance Levels or to satisfy the Financial Covenants in any fiscal year, the
Board of Directors of the Company (which shall include the affirmative vote of
the Purchasers Designees (as such term is defined in the Appaloosa Agreement))
may award Employee a cash bonus in an amount to be determined by the Company's
Board of Directors in its sole discretion. If Employee meets or exceeds certain
additional performance goals beyond the Target Performance Levels (or, in the
absence of specified Target Performance Levels, the Financial Covenants) (the
"Superior Performance Levels"), Employee shall be entitled to receive an
additional cash bonus equal to up to an additional 40% of the Base Salary (the
"Extra Bonus"). The sum of the Base Bonus and the Extra Bonus for any fiscal
year shall not exceed 100% of the Base Salary.

         (b)      Upon payment in full of the Appaloosa Notes, the Company and
Employee agree to negotiate in good faith to revise the terms of this Section
3.2 in order to establish a new mechanism for determining Employee's eligibility
for a cash bonus.

         (c)      Notwithstanding subsections (b) and (c) of this Section 3.2,
so long as Employee has been continuously employed by the Company from the
Commencement Date through December 31, 2000, the Company shall pay to Employee a
guaranteed minimum cash bonus of $75,000 for fiscal year 2000, regardless of
whether or not Employee meets or exceeds the Target Performance Levels and/or
the Superior Performance Levels. Collectively, the Base Bonus and the Extra
Bonus are referred to herein as the "Bonus".

         3.3      Stock Options. (a) Upon receipt of stockholder approval of an
amendment to the Long Term Incentive Plan increasing the number of shares of the
Company's Common Stock subject to the Long Term Incentive Plan (the "Stockholder
Approval"), the Company will issue to Employee a Non-Qualified Stock Option
under the Long Term Incentive Plan to purchase up to 700,000 shares of Common
Stock (the
<PAGE>   5
"Initial Options"). The stock option agreement pursuant to which the
Initial Options are granted will provide that the Initial Options vest in
accordance with the following schedule and shall contain such other terms and
conditions as are reasonable and customary:

<TABLE>
<CAPTION>
    Number of Years That Have Expired     Number of Options Available for
       Since the Commencement Date                    Exercise
<S>                                       <C>
                    1                                 233,333

                    2                                 233,333

                    3                                 233,334
</TABLE>

The exercise price for the Initial Options shall be determined on a date
following Stockholder Approval and the Commencement Date (as hereinafter
defined) (but no later than thirty (30) days following the date of Stockholder
Approval) mutually agreed upon by the Board of Directors and Employee and shall
be equal to the closing price of a share of Common Stock as reported on The
NASDAQ SmallCap Stock Market (or such other stock market or automated quotation
system on which the Common Stock is then trading or quoted) on such date.

         (b)      In addition to (i) the Initial Options and (ii) any Bonus to
which Employee may be entitled pursuant to Section 3.2, the Company will grant
to Employee up to fifty thousand (50,000) Incentive Stock Options (the
"Performance Options") per fiscal year pursuant to the Long Term Incentive Plan
if the Company exceeds certain agreed upon performance goals set forth in the
Annual Plan. If there is no Annual Plan, or if there are no Target Performance
Levels set forth in the Annual Plan, Employee shall be entitled to that number
of Performance Options determined by the Company's Board of Directors if the
Company achieves or surpasses the Financial Covenants applicable to such fiscal
year. In the absence of (i) an Annual Plan (or in the absence of Target
Performance Levels in such Annual Plan) for fiscal year 2000 and (ii) Financial
Covenants for such fiscal year, Employee shall be entitled to that number of
Performance Options determined by the Company's Board of Directors if the
Company achieves or surpasses all of the projections set forth in Quarterly
Budgets (as such term is defined in the Appaloosa Agreement) required to be
prepared by the Company by Section 6.32 of the Appaloosa Agreement. The
Performance Options will be granted over a four-year period and the aggregate
number of Performance Options to be granted by the Company to Employee during
such four year period shall not exceed two hundred thousand (200,000). The
agreement(s) pursuant to which the Performance Options are granted will contain
such terms and conditions as established by the Board of Directors (or a
committee thereof), will provide that the Performance Options will vest ratably
over a three year period (e.g. each time Performance Options are granted such
options will vest
<PAGE>   6
over three years from the date of such grant), and will provide that the
exercise price of the Performance Options will be equal to the closing price of
a share of Common Stock as reported on The NASDAQ SmallCap Stock Market (or such
other stock market or automated quotation system on which the Common Stock is
then trading or quoted) on the date of grant of such options.

         (c)      Notwithstanding anything to the contrary, the stock option
agreements pursuant to which the Initial Options and the Performance Options, if
any, are issued shall provide, among other things, that upon Employee's death
any of such options which are exercisable by Employee at the time of his death
may be exercised by Employee's estate or successor for a one (1) year period
following Employee's death.

         3.4      Benefits.

         (a)      Benefit Plans. During the Employment Term, Employee may
participate, on the same basis and subject to the same qualifications as other
personnel of the Company, in any benefit plans and policies of the Company in
effect or that will be developed over time; provided, however, that the Company
shall pay to or on behalf of Employee up to $6,000 per annum which funds shall
be used to pay the premiums for healthcare and dental coverage for Employee and
his family under any healthcare and/or dental benefit plans of the
Kimberly-Clark Corporation (or any successor thereto) selected by Employee;
provided, further, that so long as the Company is paying the foregoing amounts
to Employee, Employee shall not be entitled to coverage under the Company's
healthcare and dental benefit plans.

         (b)      Reimbursement of Expenses. During the Employment Term, Company
shall pay or promptly reimburse Employee, upon submission of proper invoices in
accordance with the Company's normal procedures, for all reasonable
out-of-pocket business, entertainment and travel expenses incurred by Employee
in the performance of his duties hereunder.

         (c)      Relocation Expenses. Upon the execution of this Agreement, the
Company shall pay to Employee fifty thousand dollars ($50,000) (the "Relocation
Bonus") (calculated on an after-tax basis) to cover Employee's expenses relating
to Employee's relocation to the Hartford, Connecticut area. If Employee (i)
voluntarily terminates his employment during the first twelve (12) months of the
Employment Term or (ii) is terminated by the Company for Cause during the first
twelve (12) months of the Employment Term, Employee shall repay the Relocation
Bonus to the Company within ten (10) business days of such termination.

         (d)      Vacation. During the Employment Term, Employee shall be
entitled to four weeks of vacation per year.

         (e)      Withholding. The Company shall be entitled to withhold from
amounts payable or benefits accorded to Employee under this Agreement all
federal, state
<PAGE>   7
and local income, employment and other taxes, as and in such amounts as may be
required by applicable law.

         4.       Employment Term.

         The term of this Agreement (the "Employment Term") shall commence on or
before May 29, 2000 on the day Employee actually commences to perform his duties
on a full-time basis on behalf of the Company (the "Commencement Date") and
shall end on the close of business on the third anniversary of the Commencement
Date. Upon the mutual agreement of the Company and Employee, the Employment Term
may be extended for successive twelve month periods. Employee's employment
hereunder shall be coterminous with the Employment Term, unless sooner
terminated as provided in Section 5.

         5.       Termination; Severance Benefits.

         5.1      Generally. Either the Board of Directors of the Company or
Employee may terminate Employee's employment hereunder, for any reason, at any
time prior to the expiration of the Employment Term, upon sixty (60) days prior
written notice to the other party. If termination is by the Company for Cause in
accordance with clause (i), (ii) or (iv) of the definition of Cause in Section 1
hereof, then no notice shall be required. If termination is by the Company for
Cause in accordance with clause (iii) of the definition of Cause in Section 1
hereof, then such notice shall be given as provided in such clause. Upon
termination of Employee's employment hereunder for any reason, Employee shall be
deemed simultaneously to have resigned as a member of the Board of Directors of
the Company and from any other position or office he may at the time hold with
the Company or any of its affiliates.

         5.2      Termination by Employee. (a) No Reason. If prior to the
expiration of the Employment Term, Employee voluntarily resigns from his
employment other than for Cause, Employee shall (i) be entitled only to that
portion of Base Salary accrued through the date of termination of employment
hereunder (the "Accrued Salary"), (ii) receive no further Base Salary or Bonus
hereunder and (iii) cease to be covered under or be permitted to participate in
or receive any of the Benefits. In addition, except as otherwise provided for
herein or in the Long Term Incentive Plan or in the agreement pursuant to which
such options are granted, the Initial Options and, if applicable, the
Performance Options, shall automatically cease to vest and the exerciseability
of any of such options which have vested prior to the termination of Employee's
employment shall be governed by the agreement(s) pursuant to which such options
are granted.

         (b)      Diminution in Responsibility. If, prior to the expiration of
the Employment Term, Employee terminates his employment hereunder due to a
Diminution in Responsibility, Employee shall be entitled to (i) the Accrued
Salary, (ii) salary continuation for eighteen (18) months at Employee's Base
Salary as in effect as of the termination date and (iii) cease to be covered
under or be permitted to participate in or
<PAGE>   8
receive any of the Benefits. In addition, a pro-rata portion (based on the
number of days which have elapsed in the Employment Term) of all of the Initial
Options and Performance Options previously granted shall immediately become
fully vested.

         5.3      Termination by the Company.

         (a)      Without Cause. If, prior to the expiration of the Employment
Term, the Company terminates Employee's employment hereunder without Cause,
Employee shall be entitled to (i) the Accrued Salary and (ii) salary
continuation for eighteen (18) months at Employee's Base Salary as in effect as
of the termination date. In addition, a pro-rata portion (based on the number of
days which have elapsed in the Employment Term) of all of the Initial Options
and any Performance Options previously granted shall immediately become fully
vested. Notwithstanding the foregoing, if Employee's employment is terminated
pursuant to this section during the first six months of the Employment Term and
subsequent to such termination Employee secures new employment in a Competitive
Business (as hereinafter defined), Employee shall so notify the Company and the
Company's obligation to make salary continuation payments to Employee as
provided in this Section 5.2(a)(ii) shall cease as of the date of receipt of
such notice and the Restrictive Covenants (as hereinafter defined) provided for
in Section 7 shall automatically be of no further force or effect with respect
to Employee. The provisions of the foregoing sentence shall have no effect on
any other rights or obligations of the Company or Employee provided for herein.

         (b)      For Cause. If, prior to the expiration of the Employment Term,
the Company terminates Employee's employment hereunder for Cause, Employee shall
(i) receive no further Base Salary or Bonus hereunder and (ii) cease to be
covered under or be permitted to participate in or receive any of the Benefits.
In addition, except as otherwise provided for herein or in the Long Term
Incentive Plan or in the agreement pursuant to which such options are granted,
the Initial Options and, if applicable, the Performance Options, shall
automatically cease to vest and the exerciseability of any of such options which
have vested prior to the termination of Employee's employment shall be governed
by the agreement(s) pursuant to which such options are granted. Notwithstanding
the foregoing, if Employee is terminated for Cause hereunder solely as a result
of being convicted of a felony, which conviction is ultimately reversed on
appeal or pardoned, Employee shall be deemed to have been terminated without
Cause as of the date of such termination for Cause. In such case, Employee shall
be entitled to the payments to which he would otherwise be entitled under
Section 5.3(a).

         (c)      Upon Permanent Disability. If, prior to the expiration of the
Employment Term, the Company terminates Employee's employment hereunder upon
Employee's Permanent Disability, Employee shall be entitled to (i) the Accrued
Salary and (ii) salary continuation for eighteen (18) months at Employee's Base
Salary as in effect as of the termination date. In addition, a pro-rata portion
(based on the number of days which have elapsed in the Employment Term) of all
of the Initial Options and any
<PAGE>   9
Performance Options previously granted shall immediately become fully vested.
Employee shall not be entitled to any of the Benefits except to the extent
provided in the benefit plans and programs of the Company in which Employee was
a participant prior to his termination due to Permanent Disability.

         (d)      Upon Death. If, prior to the expiration of the Employment
Term, Employee dies, Employee (or Employee's estate or successors) shall (i) be
entitled to the Base Salary accrued through the date of Employee's death, (ii)
be entitled to any Bonus and/or Performance Options to which Employee is
entitled for services provided in a prior fiscal year of the Company and which
Bonus and/or Performance Options have not yet been paid and/or issued, as the
case may be, prior to Employee's death and (iii) cease to be covered under or
receive any of the Benefits, except as may be provided in the benefit plans and
programs of the Company in which Employee was a participant prior to his death.

         (e)      Change in Control. In the event of a Change in Control
pursuant to which the Company, or any successor thereto, terminates Employee's
employment hereunder for any reason other than Cause during the nine (9) month
period following the occurrence of such Change in Control, Employee shall be
entitled to (i) the Accrued Salary, and (ii) a lump sum payment equal to two (2)
times his Base Salary in effect on the termination date of Employee's
employment. In addition, the Initial Options and any Performance Options
previously granted shall immediately become fully vested.

         6.       Confidentiality. Employee agrees to execute and deliver the
Company's standard form of confidentiality and inventions agreement.

         7.       Non-competition. For so long as Employee is an officer,
director, or employee of the Company, and for a period of time equal to (i) in
the case of the termination of Employee's employment pursuant to Sections 5.2(a)
or 5.3(b), six months after the date of such termination, (ii) in the case of
the termination of Employee's employment pursuant to Sections 5.2(b), 5.3(a) or
5.3(c), the period of salary continuation provided for in such section and (iii)
in the case of the termination of Employee's employment pursuant to Section
5.3(e), twenty four months after the date of such termination, Employee shall
not, in any county and/or city in the State of Connecticut, the United States of
America or any county or political subdivision in any state or country in the
world, for any reason whatsoever, (A) directly or indirectly engage in a
Competitive Business whether such engagement shall be as an employer, officer,
director, owner, employee, partner, member or other participant; provided,
however, that Employee shall not be deemed to be engaged in a Competitive
Business solely by his ownership of less than 5% of any class of securities
which class of securities have been registered under Section 12 of the
Securities Exchange Act of 1934, as amended or (B) assist others, whether as a
consultant, agent or independent contractor, in engaging in a Competitive
Business; or (C) induce (whether through recruitment, solicitation of employment
or otherwise) employees of the Company or any of its affiliates to terminate
<PAGE>   10
their employment therewith. For purposes of this Agreement, "Competitive
Business" shall mean any business involving the development of, or sales and
marketing of safety needles and related products.

         (a)      If Employee breaches, or threatens to commit a breach of any
of the provisions of this Section 7 (the "Restrictive Covenants"), the Company
shall have the right and remedy to have the Restrictive Covenants specifically
enforced by any court of competent jurisdiction, including but not limited to
the right to entry against Employee of restraining orders and injunctions
(preliminary, mandatory, temporary and permanent) against violations, threatened
or actual, and whether or not continuing, of any of the Restrictive Covenants,
it being acknowledged and agreed by Employee that any breach or threatened
breach of any of the Restrictive Covenants would cause irreparable and
continuing injury to the Company and that money damages would not provide an
adequate remedy to the Company. The foregoing right and remedy shall be in
addition to, and not in lieu of, any other rights and remedies available to the
Company at law or in equity.

         (b)      Employee acknowledges and agrees that the Restrictive
Covenants are reasonable and valid in geographic and temporal scope and in all
other respects. The Company and Employee further acknowledge and agree that if
any court of competent jurisdiction determines that any of the Restrictive
Covenants, or any part thereof, is invalid or unenforceable for any reason, (i)
the Restrictive Covenants contained herein shall be restricted to such extent as
such court determines to be reasonable and (ii) that it is clearly the intent of
the parties that the remainder of the Restrictive Covenants and parts thereof
shall not thereby be affected and shall be given full effect, without regard to
the invalid portions. No provision herein shall be dependent upon the validity
of any other provision. Any modification of the Restrictive Covenants, or any
part thereof, by any court of competent jurisdiction shall only be effective
with respect to the operation of such covenant (or part thereof) in the
particular jurisdiction in which such adjudication is made.

         8.       General.

         8.1      Governing Law. This Agreement shall be construed, interpreted
and governed by the laws of the State of Connecticut, without regard to the

has sought and obtained the advice of legal counsel before agreeing to be bound
by the terms hereof.
