Executive shall be paid for the balance of the Term the Base Salary then in
effect; provided that if Executive's notice of termination occurs within ninety
        --------
(90) days of a reduction in Executive's Base Salary, the Base Salary prior to
the reduction shall be used for purposes of this Section 2.05.  In addition to
these termination payments, for the balance of the Term, the Company will
provide Executive with health and dental insurance coverage as though Executive
remained an employee.  Executive will be required to pay the same portion of the
premium for such insurance coverage as if Executive remained an employee.

                his or her employment with the Company for any reason by
                providing notice (as provided for in Section 2.04) of

Other Rights. (a) Executive shall disclose promptly to the Company or its

nominee any and all works, inventions, discoveries and improvements authored,
conceived or made by Executive during the period of employment and related to
the business, prospective business or activities of the Company, and hereby

its nominee. Whenever requested to do so by the Company, Executive shall execute
any and all applications, assignments or other instruments, and otherwise
cooperate with the Company at no expense to Executive, to assist the Company in
applying for and obtaining Letters Patent or Copyrights of the United States or
any foreign country or to otherwise protect the Company's interest therein. Such
obligations shall continue beyond the termination of employment with respect to
works, inventions, discoveries and improvements authored, conceived or made by
Executive during the period of employment, and shall be binding upon Executive's
assigns, executors, administrators and other legal representatives.

          (b) Executive agrees that in the event of publication by Executive of
written or graphic materials the Company will retain and own all rights in said
materials, including right of copyright.

          4.03. Duties. Executive agrees to be a loyal employee of the Company.
                ------
Executive agrees to devote his or her best efforts full time to the performance
of his or her duties for the Company, to give proper time and attention to
furthering the Company's business, and to comply with all rules, regulations and
instruments established or issued by the Company. Executive further agrees that
during the term of this Agreement, Executive shall not, directly or indirectly,
engage in any business which would detract from Executive's ability to apply his
or her best efforts to the performance of his or her duties hereunder. Executive
also agrees that he shall not usurp any corporate opportunities of the Company.

          4.04. Return of Materials. Upon the termination of Executive's
                -------------------
employment with the Company for any reason, including without limitation
termination by the Company for cause or without cause, Executive shall promptly
deliver to the Company all correspondence, drawings, blueprints, manuals,
letters, notes, notebooks, reports, flow-charts, programs, proposals and any
documents concerning the Company's customers or concerning products or processes
used by the Company and, without limiting the foregoing, will promptly deliver
to the Company any and all other documents or materials containing or
constituting Confidential Information.

          4.05. Restrictions on Competition. Executive covenants and agrees that
                ---------------------------
during the period of Executive's employment hereunder plus a period of two years
(or such longer period, not in excess of three years, in respect of which base
salary is paid to Executive pursuant to (S) 2.04 or 2.05) following the
termination of Executive's employment, including without limitation termination
by the Company for cause or without cause, Executive shall not, in the United
States of America or in any other country of the world in which the Company has
done business at any time during the last three years prior to termination of
Executive's employment with the Company, engage, directly or indirectly, whether
as principal or as agent, officer, director, employee, consultant, shareholder,
or otherwise, alone or in association with any other person, corporation or
other entity, in any Competing Business. For purposes of this Agreement, the
term "Competing Business" shall mean and include any person, corporation or
other entity which develops, manufactures, sells, markets or attempts to
develop, manufacture, sell or market any

                                      -8-
<PAGE>

product or services which are the same as, similar to or compete with the
Products and services (i) sold by the Company at any time and from time to time
during the last three years prior to the termination of Executive's employment
hereunder or (ii) which are active research and development projects of the
Company of which Executive is aware at the time of termination; provided,
however, that for purposes of determining what constitutes a Competing Business
there shall not be included (x) any product or service of any entity which
product or service Executive determines is not material to the business or
prospects of the Company and which product or service the Company's Board,
having been requested to do so by Executive, also so determines; or (y) any
product or service of any entity so long as the Executive and such entity can
demonstrate to the reasonable satisfaction of the Company that Executive is and
will continue to be effectively isolated from and not participate in the
development, manufacture, sale or marketing of such product or service, but only
so long as Executive is effectively so isolated and does not so participate. In
the event the employment of Executive terminates at the conclusion of the Term
before Executive obtains the age of 65 and because the Company has elected not
to further extend the Term pursuant to (S) 1.02, then the provisions of this (S)
4.05 and (S)'s 4.06 and 4.07 shall not be applicable after the conclusion of the
Term unless the Company advises Executive at least six months prior to
conclusion of the Term that it will continue to pay the Base Salary in effect at
conclusion of the Term for such two-year period or such shorter portion thereof
as the Company may specify (which specification shall foreshorten such two-year
period accordingly) and the Company pays such amounts during such two-year or
shorter period.

                -------------------------------------------
that during his or her employment with the Company he or she shall not, directly
or indirectly, solicit the trade of, or trade with, any customer, prospective
customer, supplier, or prospective supplier of the Company for any business
purpose other than for the benefit of the Company, with respect to any products
competitive with those of the Company. Executive further agrees that for two
years following termination of his or her employment with the Company, including
without limitation termination by the Company for cause or without cause,
Executive shall not, directly or indirectly, solicit the trade of, or trade
with, any customers or suppliers, or prospective customers or suppliers, of the
Company with respect to any products competitive with those of the Company.

          4.07. Non-Solicitation of Employees. Executive agrees that, during his
                -----------------------------
or her employment with the Company and for two years following termination of
Executive's employment with the Company, including without limitation
termination by the Company for cause or without cause, Executive shall not,
directly or indirectly, solicit or induce, or attempt to solicit or induce, any
employee of the Company to leave the Company for any reason whatsoever, or hire
any employee of the Company.


                                   ARTICLE V
                   EXECUTIVE'S REPRESENTATIONS AND WARRANTIES
                   ------------------------------------------

          5.01. No Prior Agreements. Executive represents and warrants that he
                -------------------
or she is not a party to or otherwise subject to or bound by the terms of any
contract, agreement or understanding which in any manner would limit or
otherwise affect his or her ability perform his or her obligations hereunder,
including without limitation any contract, agreement or

                                      -9-
<PAGE>

understanding containing terms and provisions similar in any manner to those
contained in Article IV hereof. Executive further represents and warrants that
his or her employment with the Company will not require him or her to disclose
or use any confidential information belonging to prior employers or other
persons or entities.

          5.02. Executive's Abilities. Executive represents that his or her
                ---------------------
experience and capabilities are such that the provisions of Article IV will not
prevent him or her from earning his or her livelihood, and acknowledges that it
would cause the Company serious and irreparable injury and cost if Executive
were to use his or her ability and knowledge in competition with the Company or
to otherwise breach the obligations contained in Article IV.

          5.03. Remedies. In the event of a breach by Executive of the terms of
                --------
this Agreement, the Company shall be entitled, if it shall so elect, to
institute legal proceedings to obtain damages for any such breach, or to enforce
the specific performance of this Agreement by Executive and to enjoin Executive
from any further violation of this Agreement and to exercise such remedies
cumulatively or in conjunction with all other rights and remedies provided by
law. Executive acknowledges, however, that the remedies at law for any breach by
him or her of the provisions of this Agreement may be inadequate and that the
Company shall be entitled to injunctive relief against him or her in the event
of any breach.


                                   ARTICLE VI
                                 MISCELLANEOUS
                                 -------------

          6.01. Authorization to Modify Restrictions. It is the intention of the
                ------------------------------------
parties that the provisions of Article IV hereof shall be enforceable to the
fullest extent permissible under applicable law, but that the unenforceability
(or modification to conform to such law) of any provision or provisions hereof
shall not render unenforceable, or impair, the remainder thereof. If any
provision or provisions hereof shall be deemed invalid or unenforceable, either
in whole or in part, this Agreement shall be deemed amended to modify, as
necessary, the offending provision or provisions and to alter the bounds thereof
in order to render it valid and enforceable or, if necessary, to delete the
offending provision.

          6.02. Tolling Period. The non-competition, non-disclosure and non-
                --------------
solicitation obligations contained in Article IV hereof shall be extended by the
length of time during which Executive shall have been in breach of any of the
provisions of such Article IV.

          6.03. Entire Agreement. This Agreement represents the entire agreement
                ----------------
of the parties with respect to the employment of Executive by the Company and
may be amended only by a writing signed by each of them.  To the extent any
obligation on Executive set forth in Article IV herein should be held invalid or
unenforceable, the obligations on Executive with respect to such Section shall
revert back to the obligations on Executive set forth in the corresponding
Section of the Original Agreement.

          6.04. Governing Law. This Agreement shall be governed by and construed
                -------------
in accordance with the laws of the Commonwealth of Pennsylvania.

                                      -10-
<PAGE>

          6.05. Consent to Jurisdiction; Venue. Executive hereby irrevocably
                ------------------------------
submits to the personal jurisdiction of the United States District Court for the
Western District of Pennsylvania or the Court of Common Pleas of Allegheny
County, Pennsylvania in any action or proceeding arising out of or relating to
this Agreement, and Executive hereby irrevocably agrees that all claims in
respect of any such action or proceeding may be heard and determined in either
such court. Executive hereby irrevocably waives any objection which he or she
now or hereafter may have to the laying of venue of any action or proceeding
arising out of or relating to this Agreement brought in the United States
District Court for the Western District of Pennsylvania or the Court of Common
Pleas of Allegheny County, Pennsylvania and any objection on the ground that any
such action or proceeding in either of such Courts has been brought in an
inconvenient forum. Nothing in this Section 6.05 shall affect the right of the
Company to bring any action or proceeding against Executive or his or her
property in the courts of other jurisdictions where the Executive resides or has
his or her principal place of business or where such property is located.

          6.06. Service of Process. Executive hereby irrevocably consents to the
                ------------------
service of any summons and complaint and any other process which may be served
in any action or proceeding arising out of or related to this Agreement brought
in the United States District Court for the Western District of Pennsylvania or
the Court of Common Pleas of Allegheny County by the mailing by certified or
registered mail of copies of such process to Executive at his or her address as
set forth on the signature page hereof.

          6.07. Agreement Binding. The obligations of Executive under this
                -----------------
Agreement shall continue after the termination of his or her employment with the
Company for any reason, with or without cause, and shall be binding on, and
inure to the benefit of, his or her heirs, executors, legal representatives and
assigns. If the Executive should die while any amounts are still payable to him
or her hereunder, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to the Executive's devisee,
legatee, or designee or, if there be no such designee, to the Executive's
estate.  This Agreement also shall be binding upon, and inure to the benefit of,
any successors and assigns of the Company.

          6.08. Successor to the Company.  The Company will require any
                ------------------------
successor or assign (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or
assets of the Company, by agreement in form and substance satisfactory to the
Executive, to expressly, absolutely and unconditionally to assume and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession or assignment had
taken place.  Any failure of the Company to obtain such agreement prior to the
effectiveness of any such succession or assignment shall be a material breach of
this Agreement and shall entitle the Executive to terminate the Executive's
employment and to receive the payments and other benefits set forth in Section
2.06(b) as if Executive had been terminated without cause upon a Change of
Control.  As used in this Agreement, "Company" shall mean the Company as
hereinbefore defined and any successor or assign to its business and/or assets
as aforesaid.

          6.09. Counterparts, Section Headings. This Agreement may be executed
                ------------------------------
in any number of counterparts, each of which shall be deemed to be an original,
but all of which together shall constitute one and the same instrument. The
section headings of this Agreement

                                      -11-

interpretation of any of the provisions hereof.
