which the Company and Employee have achieved, as determined by the Board of
Directors; provided, however, that in no event shall Employee be entitled to any

as determined by the Board of Directors.

               (c)    STOCK OPTIONS.

                      (i) GENERAL TERMS. As soon as practicable after the
Closing Date, the Company agrees to use its best efforts to cause to be granted
to Employee an option to purchase up to seven hundred thousand (700,000) shares
of Common Stock of IPL Systems, Inc., a Massachusetts corporation ("IPL"), at an
exercise price equal to the fair market value of the Common Stock of IPL on the
date of grant (the "Option"). The Option shall be a nonstatutory stock option
and is not intended to qualify as an "incentive stock option" within the meaning
of Section 422 of the Internal Revenue Code of 1986, as amended. The Option
shall be granted under IPL's standard form of nonstatutory stock option
agreement used in connection with its employee stock option plans. The shares of
Common Stock underlying the Option shall have been registered pursuant to the
Securities Act of 1933, as amended, such that the shares when issued shall be
shall be freely tradable (subject to any restrictions that may be imposed on
"control shares" and restrictions generally placed on officers, directors or 5%
or greater shareholders of a company).

                      (ii) VESTING. The shares of Common Stock underlying the
Option shall vest and the Option shall become exercisable as follows:

                           (1) During the first year of this Agreement (the
"Initial Vesting Period"), 250,000 shares shall vest ratably and monthly
commencing on the date of this Agreement;

                           (2) 225,000 shares shall vest at the rate of 56,250
shares per year at the end of each year during the four-year period commencing
on the first anniversary of the end of the Initial Vesting Period;




                                       5.
   6

                           (3) an additional 225,000 shares shall vest at the
rate of 56,250 per year at the end of each year during the four-year period
commencing on the first anniversary of the end of the Initial Vesting Period,
provided, that, the Company meets 100% of Plan for the fiscal year in which such
vesting date occurs (that portion of the Option vesting in any fiscal year under
this Section 4(c)(ii)(3) being referred to herein as the "Contingent Option").
If the Company fails to achieve 100% of Plan during any fiscal year, Employee
shall be entitled to receive only that percentage of the Contingent Option that
is equal to that percentage of the Business Plan that the Company and Employee
have achieved; provided, however, that in no event shall Employee be entitled to
any portion of the Contingent Option that would otherwise vest in any fiscal
year if the Company and Employee fail to achieve at least 90% of Plan for such
fiscal year, as determined by the Board of Directors. Any portion of the
Contingent Option that fails to vest as set forth in this Section 4(c)(ii)(3)
shall expire and no longer be exercisable and in no event shall the shares
subject to any portion of the Contingent Option that expires under this Section
4(c)(ii)clause (3) be carried forward to any subsequent fiscal year.

                      (iii) LOCK-UP PERIOD. Employee acknowledges that the
shares of Common Stock of IPL underlying the Option shall be subject to certain
restrictions on disposition and in that regard Employee shall execute the form
of Lock-Up Agreement attached hereto as Exhibit A.

                      (iv) GOOD FAITH NEGOTIATION. In the event the Company is
unable to cause to be granted to Employee the Option, the Company and Employee
agree to negotiate in good faith alternative compensation to be paid to Employee
that is reasonably equivalent in value to the Option; provided, however, that
payment of such alternative compensation shall be in a manner that reasonably
correlates to the time period in which the Option would have vested in
accordance with this Agreement.

               (d)    ADDITIONAL COMPENSATION AND BENEFITS. During the term of
this Agreement:

                      (i) Employee shall be entitled to five (5) weeks paid
vacation in each twelve-month period during Employee's employment hereunder;

                      (ii) the Company shall pay or reimburse Employee for all
reasonable and necessary travel and other business expenses incurred or paid by

upon approval of the Company and presentation of expense statements, vouchers,
logs and such other supporting information as the Company may reasonably request
from time to time;

                      (iii) the Company shall pay or reimburse Employee for the
annual cost of premiums for a term life insurance policy insuring the life of
Employee and providing for death benefits in the amount of One Million Dollars
($1,000,000). If Employee's employment is terminated in accordance with this
Agreement, Employee shall immediately assume sole financial responsibility for
the payment of the premiums with respect to such life insurance policy;

costs and expenses of one professional organization membership upon prior
written approval of the Company of such expenses;

                      (vi) Employee shall be entitled to participate in any
other policies, programs and benefits which the Company may, in its sole and
absolute discretion, make generally available to its other senior executives
from time to time including, but not limited to, disability insurance, pension
and retirement plans, health or medical insurance and similar programs; and

                      (vii) Employee shall be entitled to a relocation allowance
in an amount to be reasonably determined by the Company and Employee.

INFORMATION. In consideration and recognition of the fact that Employee has had,
or during the course of his employment with the Company may have, access to
Confidential Information (as hereinafter defined) of the Company or other
information and data of a secret or proprietary nature of the Company which the
Company desires to keep confidential, and that the Company has furnished, or
during the course of Employee's employment will furnish, such Confidential
Information to Employee, Employee agrees and acknowledges as follows:

techniques, and any other information of a similar nature disclosed to Employee
or otherwise made known to him as a consequence of or through his employment
with the Company (including information originated by Employee) during
Employee's employment; provided, however, that the term Confidential Information
shall not include any information that (i) at the time of the disclosure or
thereafter is or becomes generally available to and known by the public, other
than as a result of a disclosure by Employee or any agent or representative of
Employee in violation of this Agreement, or (ii) was available to Employee on a
non-confidential basis from a source other than the Company, or any of its
officers, directors, employees, agents or other representatives.

               (b) EXCLUSIVE RIGHTS; ASSIGNMENT TO COMPANY. The Company has
exclusive property rights to all Confidential Information, and Employee hereby
assigns to Company all rights he might otherwise possess in any Confidential
Information. Except as required in the performance of his duties to the Company,
Employee will not at any time during or after his employment, directly or
indirectly use, communicate, disclose, disseminate, lecture upon, publish
articles or otherwise disclose or put in the public domain, any Confidential

termination of this Agreement, or at any other time upon request. This Section 5
shall survive the termination of this Agreement and the termination of
Employee's employment with the Company.

        6.     SOLICITATION OF EMPLOYEES. In consideration and recognition of
