the terms and conditions set forth in this Agreement for the Employment Period
(as herein defined).

                  (b) Positions and Duties. (i) Commencing on the date hereof
and continuing during the Employment Period, the Executive shall serve as an
employee and the Chief Executive Officer of the Company under the supervision
and direction of the Board and shall have the normal duties, responsibilities
and authority of a Chief Executive Officer of a corporation and such other

reasonable periods of illness or other incapacity which does not constitute

not preclude the Executive from devoting reasonable time to civic and charitable
affairs and with the consent of the Board serving on a maximum of two boards

provided that such activities do not interfere in any material respect with the
performance of his duties hereunder. The Executive shall perform all services in
accordance with the policies, procedures and rules established by the Company.
In addition, the Executive shall comply with all laws, rules and regulations
that are generally applicable to the Company, its Affiliates and their
employees, directors and officers.

                  (c) Base Salary and Benefits. (i) Base Salary. During the
Employment Period, the Executive's base salary shall be in an amount set by the
Board, but under no circumstances will be less than $275,000 per annum (the
"Base Salary"), which salary shall be paid by the Company in regular
installments in accordance with the Company's general payroll

                                       4

practices and shall be subject to customary withholding. On an annual basis, the
Board shall review and determine the appropriateness of an increase in the Base
Salary as in effect as of the date of such review.

                          (ii) Benefits. During the Employment Period, in
addition to the Base Salary payable to the Executive pursuant to Section
2(c)(i), the Executive shall be entitled to participate in the Company's
employee benefit programs (including, but not limited to, option plans and
benefit programs which provide group pension, life and health insurance and
other medical benefits), as the Company, with the approval of the Board, may now
or hereafter make available generally to its management as well as the employee
benefits listed on Exhibit A hereto; provided that any awards under any option
plans shall be set by the Board, in their sole discretion. In addition, during
calendar year 2000, the Executive shall be entitled to participate at a level of
no less than 100% in the MIC Plan, with any awards under the MIC Plan to be set
by the Board, and the calculation of the bonus under the MIC Plan for the
calendar year 2000 will be made as though the transactions described in the
Merger Agreement had not occurred. Effective January 1, 2001, the MIC Plan will
be replaced by the New MIC Plan which shall be mutually agreed upon by the Board
and the Company's Chief Executive Officer. If a New MIC Plan is not agreed upon
by the Board and the Company's Chief Executive Officer, the Executive will have
substantially the same bonus opportunities as existed under the MIC Plan prior
to the date hereof, taking into account the new capital structure of the Company
and its Affiliates. All benefits the Executive shall be entitled to pursuant to
this Section 2(c)(ii) shall hereinafter be referred to as the "Benefits."

                          (iii) Expenses. The Company shall reimburse the
Executive for all reasonable and necessary business expenses incurred by the
Executive in performing his duties under this Agreement which are consistent
with the Company's policies, as approved by the Board, in effect from time to
time with respect to travel, entertainment and other business expenses subject
to the Company's receipt of supporting documentation in accordance with the
Company's customary reporting and documentation provisions.

                  (d) Term. (i) This Agreement is an employment contract for a
term of two (2) years beginning as of the date of the Closing Date of the Merger
and ending on the second anniversary of the date thereof (the "Initial
Employment Term"). At the end of the Initial Employment Term, and at the end of
each Additional Employment Term (as herein defined), unless the Company (with
the approval of the Board) has provided the Executive with at least sixty (60)
days advance written notice, so long as the Executive continues to be employed
by the Company, this employment contract shall automatically renew for a term of
one (1) year (each such additional term, an "Additional Employment Term"). The
Initial Employment Term and each Additional Employment Term shall be referred to
herein as an "Employment Term." Notwithstanding the foregoing, each Employment
Term is subject to early termination (x) by reason of the Executive's death or
Disability, (y) by resolution of the Board with or without Cause, or (z) upon
the Executive's voluntary resignation with or without Good Reason. For all
purposes under this Agreement, a delivery of a notice by the Company to the
Executive pursuant to this Section 2(d)(i) to avoid an Additional Employment
Term shall be treated as if an Employment Term has been terminated early by
resolution of the Board without Cause.

                                       5
<PAGE>   6
                          (ii) The period of the Initial Employment Term
together with each Additional Employment Term, if any, shall be referred to
herein as the "Employment Period." Notwithstanding any termination of the
Executive's employment by the Company (such termination, an "Employment
Termination"), this Agreement shall remain a valid and enforceable contract
between the parties, including without limitation Sections 3, 4 and 5 hereof.

                  (e) Employment Termination. (i) If any Employment Term is
terminated early by resolution of the Board with Cause or by reason of the
Executive's voluntary resignation without Good Reason, then the Executive shall
be entitled to receive only all previously earned and accrued but unpaid Base
Salary and vacation time up to the date of the Employment Termination (and not
any accrued but unpaid Bonus as of the date of the Employment Termination).

                          (ii) If any Employment Term is terminated early by
reason of the Executive's death or Disability, then the Executive shall be
entitled to receive only (x) all previously earned and accrued but unpaid Base
Salary and vacation time up to the date of the Employment Termination, (y) if
the date of the Employment Termination is 3 months after the commencement of a
Bonus Year, then a portion of the Bonus earned by the Executive during such
Bonus Year in which such termination occurs determined on a pro rated basis
based on the number of days of the applicable Bonus Year prior to the date of
the Employment Termination as compared to the number of days in such Bonus Year,
which payment will be made when such Bonus for such Bonus Year would otherwise
be payable and (z) any Bonus earned by the Executive during any Bonus Year which
ended prior to the date of the Employment Termination and which has not been
paid as of such date, which payment will be made when such Bonus for such Bonus
Year would otherwise be payable.

                          (iii) If any Employment Term is terminated early by
reason of the Executive's voluntary resignation with Good Reason or by
resolution of the Board without Cause, then, subject to the last sentence of
this section (iii), the Executive shall be entitled to receive only the
following: (v) all previously earned and accrued but unpaid Base Salary and
vacation time up to the date of the Employment Termination, (w) his Base Salary
and the Benefits marked on Exhibit A with an "#" for the twelve-month period
beginning on the date of the Employment Termination; provided, however, that in
lieu of providing such benefits, the Company may elect to pay to the Executive
the cost of premiums for such benefits, (x) the Benefits marked on Exhibit A
with a "+" for the three-month period beginning on the date of the Employment
Termination, (y) if the date of the Employment Termination is 3 months after the
commencement of a Bonus Year, then a portion of the Bonus earned by the
Executive during such Bonus Year in which such termination occurs determined on
a pro rated basis based on the number of days of the applicable Bonus Year prior
to the date of the Employment Termination as compared to the number of days in
such Bonus Year, which payment will be made when such Bonus for such Bonus Year
would otherwise be payable and (z) any Bonus earned by the Executive during any
Bonus Year which ended prior to the date of the Employment Termination and which
has not been paid as of such date, which payment will be made when such Bonus
for such Bonus Year would otherwise be payable. Notwithstanding these payments
or benefits, the period for which the Executive is entitled to health care
continuation coverage under Section 4980B of the Internal Revenue Code of 1986,
as amended, shall begin to run on the date of the

                                       6
<PAGE>   7
Executive's termination. As a condition to receiving any payments pursuant to
this section 2(e)(iii), the Executive shall execute and deliver to the Company a
general release (with ancillary covenants not to sue and other similar standard
provisions) of the Company and its Affiliates and their respective officers,
directors and employees from all claims of any kind whatsoever arising out of
the Executive's employment or termination thereof (including without limitation,
civil rights claims), in such form as reasonably requested by the Company;
provided, however, that the release will not affect any contractual rights the
Executive may otherwise have under the Repurchase Agreement or any stock option
plans of the Company or option agreements thereunder; and provided further that
the release shall not apply to any rights to which the Executive is entitled in
accordance with plan provisions under any employee benefit plan or fringe
benefit plan or program of the Company and its Affiliates.

                          (iv) Except as expressly provided in this Section
2(e), the Executive hereby agrees that upon and after the Employment
Termination, no severance compensation of any kind, nature or amount (including
by operation of law) shall be payable by Holdings, the Company or any of their
respective Subsidiaries or Affiliates to the Executive and the Executive hereby
irrevocably waives any claim for severance compensation of any kind, nature or
amount (including by operation of law).

                          (v) Except as expressly provided in this Section 2(e),
upon the Employment Termination, except as required by law, all of the
Executive's rights to Benefits hereunder (if any) shall cease.

                          (vi) Subject to restrictive covenants contained in
Section 5, the Executive may obtain other engagements or employment after the
date of an Employment Termination, and any compensation received or receivable
by the Executive shall not reduce any amounts which the Company is required to
pay to the Executive pursuant to this Agreement.

         3. Work Product. The Executive agrees that all inventions, drawings,
improvements, developments, methods, processes, programs, designs and all
similar or related information which relates to the Company's or any of its
Subsidiaries' actual or anticipated business or research and development or
existing or future products or services and which are conceived, developed,
contributed to or made by the Executive (either solely or jointly with others)
while employed by the Company or any of its Subsidiaries ("Work Product") shall
be the sole and exclusive property of the Company or any such Subsidiary. The
Executive will promptly disclose such Work Product to the Company and perform
all actions requested by the Company (whether during or after employment) to
establish and confirm such ownership (including, without limitation,
assignments, consents, powers of attorney and other instruments).

         4. Confidential Information. (a) The Executive acknowledges: (i) That
the Work Product, artificial intelligence systems, information, customer lists,
goodwill, observations and data disclosed to, developed by or obtained by him
while employed by the Company or any of its Subsidiaries concerning the business
or affairs of the Company or any such Subsidiary (including without limitation

are highly confidential and uniquely valuable to the Company and its
Subsidiaries;

                          (ii) That such Confidential Information is and shall

irreparably harmed by disclosure of any Confidential Information.

                  (b) Therefore, the Executive agrees: (i) That, during his
employment and for all times thereafter, except as required by law or court
order, he shall not directly or indirectly disclose to any unauthorized person
or use for his own account any Confidential Information without the prior
written consent of the Company, unless and to the extent that the aforementioned
matters become generally known to and available for use by the public other than
as a result of the Executive's acts or omissions to act;

                          (ii) To use his best efforts and diligence to
safeguard the Confidential Information and to protect it against disclosure,
misuse, espionage, loss or theft;

                          (iii) That upon the Employment Termination or at any
other time the Company may request, for whatever reason, the Executive shall

representative shall deliver) to the Company all computer equipment or backup
files of or relating to the Company and its Subsidiaries, all memoranda,
correspondence, customer data, notes, plans, records, reports, manuals,
photographs, computer tapes and software and other documents and data (and

the business of the Company or any of its Subsidiaries which he may then possess
or have under his control. If the Company requests, the Executive (or his
representative) agrees to provide written confirmation that the Executive has
returned all such materials to the Company or one of its Subsidiaries; and

                          (iv) That upon the Employment Termination or at any
other time the Company may request, for whatever reason, the Executive shall
assign all rights, title and interest in the Confidential Information, the Work
Product, all computer equipment or backup files of or relating to the Company or
any of its Subsidiaries, all memoranda, correspondence, customer data, notes,
plans, records, reports, manuals, photographs, computer tapes and software and
other documents and data (and copies thereof) relating to the Confidential

         5. Noncompete, Nonsolicitation. (a) The Executive agrees that, during
the time he is employed by the Company or any of its Subsidiaries and during any
applicable Post-Termination Period (as herein defined) (the "Noncompete
Period"), he shall not directly or indirectly own, operate, manage, control,
participate in, consult with, advise, provide services for, or in any manner
engage in any business (including by himself or in association with any person,
firm, corporate or other business organization or through any other entity) in
competition with, or potential competition with, the businesses of the Company
or any of its Subsidiaries as such businesses (the "Businesses") exist during
the Executive's employment by the Company, within the United States or any other
geographical area in which the Company or any of its Subsidiaries engages or
plans to engage in the Businesses (the "Geographical Area"). Nothing herein
shall prohibit the Executive from being a passive owner of not more than 2% of
the outstanding stock of a corporation which is publicly traded, so long as the
Executive has no active participation in the business of such corporation. For
purposes of this Section 5, "Post-Termination Period" means the twelve (12)
month period beginning on the Termination Date.

                  (b) During the Noncompete Period, the Executive shall not
directly or indirectly through another entity (i) induce or attempt to induce
any employee of the Company or any of its Subsidiaries to leave the employ of
the Company or any such Subsidiary, or in any way interfere with the
relationship between the Company or any of its Subsidiaries and any employee
thereof, including without limitation, inducing or attempting to induce any
union, employee or group of employees to interfere with the business or
operations of the Company or any of its Subsidiaries, (ii) hire any person who
was an employee of the Company or any of its Subsidiaries at any time during the
Executive's employment period, or (iii) induce or attempt to induce any
customer, supplier, distributor, franchisee, licensee or other business relation
of the Company or any of its Subsidiaries to cease doing business with the
Company or any such Subsidiary, or in any way interfere with the relationship
between any such customer, supplier, distributor, franchisee, licensee or
business relation and the Company or any of its Subsidiaries.

                  (c) The Executive agrees that: (i) the covenants set forth in
this Section 5 are reasonable in geographical and temporal scope and in all
other respects, (ii) Holdings and the Company would not have entered into this
Agreement but for the covenants of the Executive contained herein, and (iii) the
covenants contained herein have been made in order to induce Holdings and the
Company to enter into this Agreement.

                  (d) If, at the time of enforcement of this Section 5, a court
shall hold that the duration, scope or area restrictions stated herein are
unreasonable under circumstances then existing, the parties agree that the
maximum duration, scope or area reasonable under such circumstances shall be
substituted for the stated duration, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area permitted by law.

                  (e) The Executive recognizes and affirms that in the event of
his breach of any provision of this Section 5, money damages would be inadequate

the Executive agrees that in the event of a breach or a threatened breach by the
Executive of any of the provisions of this Section 5, Holdings and the Company,
in addition and supplementary to other rights and remedies existing in

its favor, may apply to any court of law or equity of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce or
prevent any violations of the provisions hereof (without posting a bond or other
security).

or use of any information which directly or indirectly relates to the nature of
the business of the Company or any of its Subsidiaries or the services to be
rendered by the Executive under this Agreement.

                  (b) Severability. If any provision or clause of this
Agreement, or portion thereof shall be held by any court or other tribunal of
competent jurisdiction to be illegal, invalid, or unenforceable in such
jurisdiction, the remainder of such provision shall not be thereby affected and
shall be given full effect, without regard to the invalid portion. It is the
intention of the parties that, if any court construes any provision or clause of
this Agreement, or any portion thereof, to be illegal, void or unenforceable
because of the duration of such provision or the area matter covered thereby,
such court shall reduce the duration, area, or matter of such provision, and, in
its reduced form, such provision shall then be enforceable and shall be
enforced.

                  (c) Complete Agreement. This Agreement shall embody the
complete agreement and understanding among the parties and supersede and preempt
any prior understandings, agreements or representations by or among the parties,

agreements evidencing the grant of options to the Executive under Holdings' 2000
Option Plan, or any future option plan of Holdings.

                  (d) Counterparts. This Agreement may be executed in separate
counterparts, each of which is deemed to be an original and all of which taken
together constitute one and the same agreement.

                  (e) Successors and Assigns, Transfer. This Agreement is
intended to bind and inure to the benefit of and be enforceable by the
Executive, Holdings and the Company and their respective successors, heirs and
assigns.

                  (f) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the state of Delaware, without giving
effect to any rules, principles or provisions of choice of law or conflict of
laws.

                  (g) Remedies. Holdings, the Company and the Executive will be
entitled to enforce its respective rights under this Agreement specifically, to
recover damages and costs (including reasonable attorneys' fees and expenses)
caused by any breach of any provision of this Agreement and to exercise all
other rights existing in its favor. The parties hereto agree and acknowledge
that Holdings and the Company will suffer irreparable harm and money damages may
not be an adequate remedy for any breach of the provisions of this Agreement by
the Executive and that any such party may in its sole discretion apply to any
court of law or equity of competent jurisdiction (without posting any bond or
deposit) for specific performance and/or other injunctive relief in order to
enforce or prevent any violations of the provisions of this Agreement.

                  (h) Amendment and Waiver. The provisions of this Agreement may
be amended and waived only with the prior written consent of Holdings (with the

                  (i) Tax Matters. (i) The Executive shall indemnify, defend and
hold harmless Holdings and the Company (and their respective officers,
directors, employees and members) for any liability associated with federal,
state or local income tax withholding and employment tax withholding in respect
of the Executive or his transferees (including all interest, penalties and
additions to tax with respect thereto) resulting from, or arising with respect
to, the issuance to the Executive of any units of interest in Holdings, whether
before or after the Merger, whether acquired by purchase from the Company or
otherwise, or the holding by the Executive or his transferees of any such units
of interest in Holdings.

                  (ii) The Executive hereby irrevocably waives any and all
claims, rights and recourse under Section 10(j) of the Old Employment Agreement.

addition to the Base Salary payable to the Executive pursuant to Section
2(c)(i), the Executive shall be entitled to participate in the Company's
employee benefit programs (including, but not limited to, option plans and
benefit programs which provide group pension, life and health insurance and
other medical benefits), as the Company, with the approval of the Board, may now
or hereafter make available generally to its management as well as the employee
benefits listed on Exhibit A hereto; provided that any awards under any option
plans shall be set by the Board, in their sole discretion. In addition, during

no less than 60% in the MIC Plan, with any awards under the MIC Plan to be set
by the Board, and the calculation of the bonus under the MIC Plan for the

Merger Agreement had not occurred. Effective January 1, 2001, the MIC Plan will
be replaced by the New MIC Plan which shall be mutually agreed upon by the Board
and the Company's Chief Executive Officer. If a New MIC Plan is not agreed upon
by the Board and the Company's Chief Executive Officer, the Executive will have
substantially the same bonus opportunities as existed under the MIC Plan prior
to the date hereof, taking into account the new capital structure of the Company
and its Affiliates. All benefits the Executive shall be entitled to pursuant to
this Section 2(c)(ii) shall hereinafter be referred to as the "Benefits."

Executive for all reasonable and necessary business expenses incurred by the
Executive in performing his duties under this Agreement which are consistent
with the Company's policies, as approved by the Board, in effect from time to
time with respect to travel, entertainment and other business expenses subject
to the Company's receipt of supporting documentation in accordance with the
Company's customary reporting and documentation provisions.

                  (d) Term. (i) This Agreement is an employment contract for a
term of two (2) years beginning as of the date of the Closing Date of the Merger
and ending on the second anniversary of the date thereof (the "Initial
Employment Term"). At the end of the Initial Employment Term, and at the end of
each Additional Employment Term (as herein defined), unless the Company (with
the approval of the Board) has provided the Executive with at least sixty (60)
days advance written notice, so long as the Executive continues to be employed
by the Company, this employment contract shall automatically renew for a term of
one (1) year (each such additional term, an "Additional Employment Term"). The
Initial Employment Term and each Additional Employment Term shall be referred to
herein as an "Employment Term." Notwithstanding the foregoing, each Employment
Term is subject to early termination (x) by reason of the Executive's death or
Disability, (y) by resolution of the Board with or without Cause, or (z) upon
the Executive's voluntary resignation with or without Good Reason. For all
purposes under this Agreement, a delivery of a notice by the Company to the
Executive pursuant to this Section 2(d)(i) to avoid an Additional Employment
Term shall be treated as if an Employment Term has been terminated early by
resolution of the Board without Cause.

                           (ii) The period of the Initial Employment Term
together with each Additional Employment Term, if any, shall be referred to
herein as the "Employment Period." Notwithstanding any termination of the
Executive's employment by the Company (such

                                      -5-
<PAGE>   6
termination, an "Employment Termination"), this Agreement shall remain a valid
and enforceable contract between the parties, including without limitation
Sections 3, 4 and 5 hereof.

                  (e) Employment Termination. (i) If any Employment Term is
terminated early by resolution of the Board with Cause or by reason of the
Executive's voluntary resignation without Good Reason, then the Executive shall
be entitled to receive only all previously earned and accrued but unpaid Base
Salary and vacation time up to the date of the Employment Termination (and not
any accrued but unpaid Bonus as of the date of the Employment Termination).

                           (ii) If any Employment Term is terminated early by
reason of the Executive's death or Disability, then the Executive shall be
entitled to receive only (x) all previously earned and accrued but unpaid Base
Salary and vacation time up to the date of the Employment Termination, (y) if
the date of the Employment Termination is 3 months after the commencement of a
Bonus Year, then a portion of the Bonus earned by the Executive during such
Bonus Year in which such termination occurs determined on a pro rated basis
based on the number of days of the applicable Bonus Year prior to the date of
the Employment Termination as compared to the number of days in such Bonus Year,
which payment will be made when such Bonus for such Bonus Year would otherwise
be payable and (z) any Bonus earned by the Executive during any Bonus Year which
ended prior to the date of the Employment Termination and which has not been
paid as of such date, which payment will be made when such Bonus for such Bonus
Year would otherwise be payable.

                           (iii) If any Employment Term is terminated early by
reason of the Executive's voluntary resignation with Good Reason or by
resolution of the Board without Cause, then, subject to the last sentence of
this section (iii), the Executive shall be entitled to receive only the
following: (v) all previously earned and accrued but unpaid Base Salary and
vacation time up to the date of the Employment Termination, (w) his Base Salary
and the Benefits marked on Exhibit A with an "#" for the twelve-month period
beginning on the date of the Employment Termination; provided, however, that in
lieu of providing such benefits, the Company may elect to pay to the Executive
the cost of premiums for such benefits, (x) the Benefits marked on Exhibit A
with a "+" for the three-month period beginning on the date of the Employment
Termination, (y) if the date of the Employment Termination is 3 months after the
commencement of a Bonus Year, then a portion of the Bonus earned by the
Executive during such Bonus Year in which such termination occurs determined on
a pro rated basis based on the number of days of the applicable Bonus Year prior
to the date of the Employment Termination as compared to the number of days in
such Bonus Year, which payment will be made when such Bonus for such Bonus Year
would otherwise be payable and (z) any Bonus earned by the Executive during any
Bonus Year which ended prior to the date of the Employment Termination and which
has not been paid as of such date, which payment will be made when such Bonus
for such Bonus Year would otherwise be payable. Notwithstanding these payments
or benefits, the period for which the Executive is entitled to health care
continuation coverage under Section 4980B of the Internal Revenue Code of 1986,
as amended, shall begin to run on the date of the Executive's termination. As a
condition to receiving any payments pursuant to this section 2(e)(iii), the
Executive shall execute and deliver to the Company a general release (with
ancillary covenants not to sue and other similar standard provisions) of the
Company and its Affiliates and

                                      -6-
<PAGE>   7
their respective officers, directors and employees from all claims of any kind
whatsoever arising out of the Executive's employment or termination thereof
(including without limitation, civil rights claims), in such form as reasonably
requested by the Company; provided, however, that the release will not affect
any contractual rights the Executive may otherwise have under the Repurchase
Agreement or any stock option plans of the Company or option agreements
thereunder; and provided further that the release shall not apply to any rights
to which the Executive is entitled in accordance with plan provisions under any
employee benefit plan or fringe benefit plan or program of the Company and its
Affiliates.

                           (iv) Except as expressly provided in this Section
2(e), the Executive hereby agrees that upon and after the Employment
Termination, no severance compensation of any kind, nature or amount (including
by operation of law) shall be payable by Holdings, the Company or any of their
respective Subsidiaries or Affiliates to the Executive and the Executive hereby
irrevocably waives any claim for severance compensation of any kind, nature or
amount (including by operation of law).

                           (v) Except as expressly provided in this Section
2(e), upon the Employment Termination, except as required by law, all of the
Executive's rights to Benefits hereunder (if any) shall cease.

                           (vi) Subject to restrictive covenants contained in
Section 5, the Executive may obtain other engagements or employment after the
date of an Employment Termination, and any compensation received or receivable
by the Executive shall not reduce any amounts which the Company is required to
pay to the Executive pursuant to this Agreement.

         3. Work Product. The Executive agrees that all inventions, drawings,
improvements, developments, methods, processes, programs, designs and all
similar or related information which relates to the Company's or any of its
Subsidiaries' actual or anticipated business or research and development or
existing or future products or services and which are conceived, developed,
contributed to or made by the Executive (either solely or jointly with others)
while employed by the Company or any of its Subsidiaries ("Work Product") shall
be the sole and exclusive property of the Company or any such Subsidiary. The
Executive will promptly disclose such Work Product to the Company and perform
all actions requested by the Company (whether during or after employment) to
establish and confirm such ownership (including, without limitation,
assignments, consents, powers of attorney and other instruments).

         4. Confidential Information. (a) The Executive acknowledges: (i) That
the Work Product, artificial intelligence systems, information, customer lists,
goodwill, observations and data disclosed to, developed by or obtained by him
while employed by the Company or any of its Subsidiaries concerning the business
or affairs of the Company or any such Subsidiary (including without limitation
the Company's and its Subsidiaries' technology, methods of doing business and
supplier and customer information) (collectively, "Confidential Information")
are highly confidential and uniquely valuable to the Company and its
Subsidiaries;

                           (ii) That such Confidential Information is and shall
continue to be the property of the Company or any such Subsidiary;

                                      -7-
<PAGE>   8
                           (iii) That the Company and each of its Subsidiaries
has a proprietary interest in their respective Confidential Information,
including without limitation the identity of their respective customers and
suppliers, solicited customers, customer and supplier lists;

                           (iv) That the continued success of the Company and
its Subsidiaries depends in large part on keeping the Confidential Information
from becoming known to competitors of the Company and its Subsidiaries; and

                           (v) That the Company and its Subsidiaries will be
irreparably harmed by disclosure of any Confidential Information.

                  (b) Therefore, the Executive agrees: (i) That, during his
employment and for all times thereafter, except as required by law or court
order, he shall not directly or indirectly disclose to any unauthorized person
or use for his own account any Confidential Information without the prior
written consent of the Company, unless and to the extent that the aforementioned
matters become generally known to and available for use by the public other than
as a result of the Executive's acts or omissions to act;

                           (ii) To use his best efforts and diligence to
safeguard the Confidential Information and to protect it against disclosure,
misuse, espionage, loss or theft;

                           (iii) That upon the Employment Termination or at any
other time the Company may request, for whatever reason, the Executive shall
deliver (and in the event of the Executive's death or Disability, his
representative shall deliver) to the Company all computer equipment or backup
files of or relating to the Company and its Subsidiaries, all memoranda,
correspondence, customer data, notes, plans, records, reports, manuals,
photographs, computer tapes and software and other documents and data (and
copies thereof) relating to the Confidential Information, the Work Product or
the business of the Company or any of its Subsidiaries which he may then possess
or have under his control. If the Company requests, the Executive (or his
representative) agrees to provide written confirmation that the Executive has
returned all such materials to the Company or one of its Subsidiaries; and

                           (iv) That upon the Employment Termination or at any
other time the Company may request, for whatever reason, the Executive shall
assign all rights, title and interest in the Confidential Information, the Work
Product, all computer equipment or backup files of or relating to the Company or
any of its Subsidiaries, all memoranda, correspondence, customer data, notes,
plans, records, reports, manuals, photographs, computer tapes and software and
other documents and data (and copies thereof) relating to the Confidential
Information, the Work Product or the business of the Company or any of its
Subsidiaries which the Executive may then possess, has under his control, or has
ever developed, obtained, or contributed to during his tenure with the Company.

         5. Noncompete, Nonsolicitation. (a) The Executive agrees that, during
the time he is employed by the Company or any of its Subsidiaries and during any
applicable Post-Termination Period (as herein defined) (the "Noncompete
Period"), he shall not directly or indirectly own, operate, manage, control,
participate in, consult with, advise, provide services for,

                                      -8-
<PAGE>   9
or in any manner engage in any business (including by himself or in association
with any person, firm, corporate or other business organization or through any
other entity) in competition with, or potential competition with, the businesses
of the Company or any of its Subsidiaries as such businesses (the "Businesses")
exist during the Executive's employment by the Company, within the United States
or any other geographical area in which the Company or any of its Subsidiaries
engages or plans to engage in the Businesses (the "Geographical Area"). Nothing
herein shall prohibit the Executive from being a passive owner of not more than
2% of the outstanding stock of a corporation which is publicly traded, so long
as the Executive has no active participation in the business of such
corporation. For purposes of this Section 5, "Post-Termination Period" means the
twelve (12) month period beginning on the Termination Date.

                  (b) During the Noncompete Period, the Executive shall not
directly or indirectly through another entity (i) induce or attempt to induce
any employee of the Company or any of its Subsidiaries to leave the employ of
the Company or any such Subsidiary, or in any way interfere with the
relationship between the Company or any of its Subsidiaries and any employee
thereof, including without limitation, inducing or attempting to induce any
union, employee or group of employees to interfere with the business or
operations of the Company or any of its Subsidiaries, (ii) hire any person who
was an employee of the Company or any of its Subsidiaries at any time during the
Executive's employment period, or (iii) induce or attempt to induce any
customer, supplier, distributor, franchisee, licensee or other business relation
of the Company or any of its Subsidiaries to cease doing business with the
Company or any such Subsidiary, or in any way interfere with the relationship
between any such customer, supplier, distributor, franchisee, licensee or
business relation and the Company or any of its Subsidiaries.

                  (c) The Executive agrees that: (i) the covenants set forth in
this Section 5 are reasonable in geographical and temporal scope and in all
other respects, (ii) Holdings and the Company would not have entered into this
Agreement but for the covenants of the Executive contained herein, and (iii) the
covenants contained herein have been made in order to induce Holdings and the
Company to enter into this Agreement.

                  (d) If, at the time of enforcement of this Section 5, a court
shall hold that the duration, scope or area restrictions stated herein are
unreasonable under circumstances then existing, the parties agree that the
maximum duration, scope or area reasonable under such circumstances shall be
substituted for the stated duration, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area permitted by law.

                  (e) The Executive recognizes and affirms that in the event of
his breach of any provision of this Section 5, money damages would be inadequate
and Holdings and the Company would have no adequate remedy at law. Accordingly,
the Executive agrees that in the event of a breach or a threatened breach by the
Executive of any of the provisions of this Section 5, Holdings and the Company,
in addition and supplementary to other rights and remedies existing in its
favor, may apply to any court of law or equity of competent jurisdiction for
specific performance and/or injunctive or other relief in order to enforce or
prevent any violations of the provisions hereof (without posting a bond or other
security).

         7. Miscellaneous. (a) Warranty by the Executive. The Executive
represents and warrants to Holdings and the Company that he is not a party to
any agreement containing a

                                      -10-
<PAGE>   11
noncompetition provision or other restriction with respect to (i) the nature of
any services or business which he is entitled to perform or conduct for the
Company under this Agreement, or (ii) the disclosure or use of any information
which directly or indirectly relates to the nature of the business of the
Company or any of its Subsidiaries or the services to be rendered by the
Executive under this Agreement.

                  (b) Severability. If any provision or clause of this
Agreement, or portion thereof shall be held by any court or other tribunal of
competent jurisdiction to be illegal, invalid, or unenforceable in such
jurisdiction, the remainder of such provision shall not be thereby affected and
shall be given full effect, without regard to the invalid portion. It is the
intention of the parties that, if any court construes any provision or clause of
this Agreement, or any portion thereof, to be illegal, void or unenforceable
because of the duration of such provision or the area matter covered thereby,
such court shall reduce the duration, area, or matter of such provision, and, in
its reduced form, such provision shall then be enforceable and shall be
enforced.

                  (c) Complete Agreement. This Agreement shall embody the
complete agreement and understanding among the parties and supersede and preempt
any prior understandings, agreements or representations by or among the parties,
written or oral, which may have related to the subject matter hereof in any way,
including, but not limited to, the Term Sheet between GEEG Acquisition, L.L.C.
and the Executive Relating to the Term of Employment and Equity Compensation,
dated July 12, 2000, the Old Employment Agreement, the Agreements evidencing the
grant of Performance Vesting Options and Time Vesting Options to the Executive
under the Holdings' 1998 Option Plan, and the Employee Subscription Agreements,
dated June 8, 1998 and December 18, 1998, between Holdings and the Executive.
This Agreement does not supersede the Repurchase Agreement between Holdings and
the Executive which is being executed concurrently herewith, or any future
agreements evidencing the grant of options to the Executive under Holdings' 2000
Option Plan, or any future option plan of Holdings.

                  (d) Counterparts. This Agreement may be executed in separate
counterparts, each of which is deemed to be an original and all of which taken
together constitute one and the same agreement.

                  (e) Successors and Assigns, Transfer. This Agreement is
intended to bind and inure to the benefit of and be enforceable by the
Executive, Holdings and the Company and their respective successors, heirs and
assigns.

                  (f) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the state of Delaware, without giving
effect to any rules, principles or provisions of choice of law or conflict of
laws.

                  (g) Remedies. Holdings, the Company and the Executive will be
entitled to enforce its respective rights under this Agreement specifically, to
recover damages and costs (including reasonable attorneys' fees and expenses)
caused by any breach of any provision of this Agreement and to exercise all
other rights existing in its favor. The parties hereto agree and acknowledge
that Holdings and the Company will suffer irreparable harm and money damages may
not be an adequate remedy for any breach of the provisions of this Agreement by
the

                                      -11-
<PAGE>   12
Executive and that any such party may in its sole discretion apply to any court
of law or equity of competent jurisdiction (without posting any bond or deposit)
for specific performance and/or other injunctive relief in order to enforce or
prevent any violations of the provisions of this Agreement.

                  (h) Amendment and Waiver. The provisions of this Agreement may
be amended and waived only with the prior written consent of Holdings (with the
approval of the Board), the Company and the Executive.

                  (i) Tax Matters. (i) The Executive shall indemnify, defend and
hold harmless Holdings and the Company (and their respective officers,
directors, employees and members) for any liability associated with federal,
state or local income tax withholding and employment tax withholding in respect
of the Executive or his transferees (including all interest, penalties and
additions to tax with respect thereto) resulting from, or arising with respect
to, the issuance to the Executive of any units of interest in Holdings, whether
before or after the Merger, whether acquired by purchase from the Company or
otherwise, or the holding by the Executive or his transferees of any such units
of interest in Holdings.

                  (ii) The Executive hereby irrevocably waives any and all
claims, rights and recourse under Section 10(j) of the Old Employment Agreement.
