                   (b)  Should the Company be unable to secure Executive's
signature on any document necessary to apply for, prosecute, obtain or enforce
any patent, copyright or other right or protection relating to any Intellectual
Property, whether due to Executive's Disability or other reason, Executive
hereby irrevocably designates and appoints the Company and each of its duly
authorized officers and agents as Executive's agent and attorney-in-fact to act
for and on Executive's behalf and stead and to execute and file any such

protections with the same effect as if executed and delivered by Executive.

              4.5  ENFORCEMENT.

                   (a)  Executive acknowledges that violation of any covenant or
agreement set forth in this Article IV would cause the Company irreparable
damage for which the Company cannot be reasonably compensated in damages in an
action at law, and, therefore, upon any breach by Executive of this Article IV,
the Company shall be entitled to make application to a court of competent
jurisdiction for equitable relief by way of injunction or otherwise (without
being required to post a bond). This provision shall not, however, be construed
as a waiver of any of the rights which the Company may have for damages, and all
of the Company's rights and remedies shall be unrestricted.

                   (b)  If any provision of this Agreement, or application
thereof to any person, place or circumstance, shall be held by a court of
competent jurisdiction or be found in an arbitration proceeding to be invalid,
unenforceable or void, the remainder of this Agreement and such provisions as
applied to any other person, place and circumstance shall remain in full force
and effect. It is the intention of the parties hereto that the covenants
contained herein shall be enforced to the maximum extent (but no greater extent)
in time, area, and degree of participation as is permitted by the law of the
jurisdiction whose law is found to be applicable to the acts allegedly in breach
of this agreement, and the parties hereby agree that the court making any such
determination shall have the power to so reform the Agreement.

                   (c)  The Executive understands that the provisions of this
Article IV may limit his ability to earn a livelihood in a business similar to
the business of the Company but nevertheless agrees and hereby acknowledges that
(i) such provisions do not impose a greater restraint than is necessary to
protect the goodwill or other business interests of the Company; (ii) such
provisions contain reasonable limitations as to time and the scope of activity
to be restrained; and (iii) the consideration provided under this Agreement,
including, without limitation, any amounts or benefits provided under Article V
hereof, is sufficient to compensate Executive for the restrictions contained in
this Article IV. In consideration of the foregoing and in light of Executive's
education, skills and abilities, Executive agrees that he will not assert, and
it should not be considered, that any provisions of this Article IV prevented
him from earning a living or otherwise are void, voidable or unenforceable or
should be voided or held unenforceable.

                   (d)  Each of the covenants of this Article IV is given by
Executive as part of the consideration for this Agreement and as an inducement
to the Company to enter into this Agreement and accept the obligations
hereunder.

                                    ARTICLE V

                                   TERMINATION

              5.1  TERMINATION OF AGREEMENT. Except as otherwise provided, this
Agreement shall become invalid upon any Termination of employment.

              5.2  PROCEDURES APPLICABLE TO TERMINATION.

                   (a)  TERMINATION FOR CAUSE. The Executive may be terminated
for Cause, upon prior written notice from the Board to Executive for termination
for Cause provided that Executive, with his counsel, shall have had the
opportunity during such period to be heard at a meeting of the Board concerning
such determination. The Executive's right to be heard in connection with a
Termination shall not otherwise effect the rights and obligations hereunder.

                   (b)  RESIGNATION FOR GOOD REASON. The Executive may terminate
his employment for Good Reason, upon prior written notice from Executive to the
Board of his intent to resign for Good Reason provided that Executive, with his
counsel, shall have met with the Board, if requested by the Board, during such
period with respect to his intent to resign. The Executive's obligation to be
heard in connection with a Termination shall not otherwise effect the rights and
obligations hereunder.

                   (c)  TERMINATION WITHOUT CAUSE. The Executive may be
terminated without Cause, upon prior written notice from the Board to Executive,
by a vote of the Board, provided that Executive, with his counsel, shall have
had the opportunity during such period to be heard at a meeting of the Board
with respect to such determination. The Executive's right to be heard in
connection with a Termination shall not otherwise effect the rights and
obligations hereunder.

                   (d)  TERMINATION FOR DISABILITY. The Executive may be
terminated for Disability, upon prior written notice from the Board to
Executive, by a vote of the Board, provided that Executive, with his counsel,
shall have had the opportunity during such period to be heard at a meeting of
the Board with respect to such determination. The Executive's right to be heard
in connection with a Termination shall not otherwise effect the rights and
obligations hereunder.

                   (e)  TERMINATION UPON A CHANGE OF CONTROL. Upon the occurence
of any transaction resulting in a Change of Control, the Executive may terminate
his employment by providing written notice of such termination to the Company
within 60 days of the effective date of such Change of Control.

              5.3  OBLIGATIONS OF THE COMPANY UPON TERMINATION.

                                      -10-

<PAGE>

                   (a)  ALL TERMINATIONS. Upon any Termination, the Company
shall pay to Executive, or, upon Executive's Disability, to his heirs, estate or
legal representatives, as the case may be, the following:

                        (i)       all Accrued Obligations in a lump sum within
10 days after the date of Termination; and

                        (ii)      all benefits accrued by Executive as of the
date of Termination under all qualified and nonqualified retirement, pension,
profit sharing and similar plans of the Company to such extent, in such manner
and at such time as are provided under the terms of such plans and arrangements.

                   (b)  TERMINATION WITHOUT CAUSE OR RESIGNATION FOR GOOD
REASON. If the Board terminates Executive's employment without Cause (excluding
Termination because of Disability), or if Executive resigns for Good Reason, in
addition to the amounts payable under Section 5.3(a) hereof:

                        (i)       The Company shall pay Executive the Severance
Payment in a lump sum within 10 days after the date of Termination; and

                        (ii)      The Company shall continue all benefits
coverage of Executive and any dependents then provided under its benefit plans
or policies for the unexpired portion of the Term.

                   (c)  TERMINATION FOR CAUSE OR RESIGNATION WITHOUT GOOD
REASON. If the Board terminates Executive's employment for Cause, or if
Executive resigns without Good Reason, Executive shall only be entitled to the
amounts payable under Section 5.3(a) hereof.

                   (d)  TERMINATION FOR DISABILITY. Upon Termination of
Executive because of a Disability, in addition to the amounts payable under
Section 5.3(a) hereof, the Company shall pay the aggregate Disability Payment
for the greater of (i) three years (in accordance with the Company's regular
payroll practices then in existence) and (ii) the period covered by any
Disability Plan.

                   (e)  TERMINATION UPON A CHANGE OF CONTROL. If Executive
provides Notice of Termination of employment within 60 days of the date that a
Change of Control occurs, in addition to the amounts payable under Section
5.3(a) hereof, Executive shall be entitled to the benefits provided below,
without regard to any contrary provision of any plan:

                        (i)       INSURANCE COVERAGE. The Company shall arrange
to provide Executive (and dependents, if applicable) with life, disability (to
the extent available at standard commercial rates), accident, dental and medical
benefits substantially equivalent to those which Executive receives, or was
entitled to receive, from the Company immediately before a Change of Control of
the Company. Such benefits shall be provided for the longer of (x) thirty six
(36) months after such Date of Termination or (y) the period during which such
benefits would have been provided to Executive, as a terminated employee, under
the applicable life, disability, accident, dental and medical plans in effect
immediately before a Change of

                                      -11-

<PAGE>

Control of the Company (except that after a period of thirty six (36) months
such benefits shall be provided on the same financial terms and conditions as
provided for under the respective plans).

                                  Should it be determined that any of the
medical benefits to be provided to Executive (and dependents, if applicable)
under this subparagraph could be included in Executive's gross income for
federal, state or local tax purposes, then the following shall apply:

                                       (A)  If Executive is retirement eligible
on Executive's Date of Termination, then Executive shall participate in the
Company's medical benefit plans as if Executive retired from the Company on
Executive's Date of Termination, except that the Company shall provide such
medical coverage at no cost to Executive for three (3) years following
Executive's Date of Termination. Thereafter, Executive shall participate therein
on the same terms as other retired employees; and

                                       (B)  If Executive is not eligible for
retirement upon Executive's Date of Termination, Executive will no longer
continue to participate in the Company's medical benefit plans and (i) the
Company shall provide Executive with a cash payment in an amount equal to the
amount required by Executive to pay for coverage under COBRA for the first
eighteen (18) months following Executive's loss of medical coverage, and
thereafter, (ii) the Company shall, for the subsequent eighteen (18) months,
purchase for Executive, at its cost, a policy of medical insurance providing
benefits substantially similar to the benefits Executive would have received
under the Company's medical benefit plans.

                        (ii)      RETIREMENT BENEFITS. (A) The Company shall pay
Executive, at the time Executive is entitled to be paid a retirement pension
under the Retirement Program, a retirement pension equal to the greater of (x)
an amount computed in accordance with the terms of any Retirement Program in
effect immediately before the Change of Control, or (y) an amount computed in
accordance with the terms of the Retirement Program in effect immediately before
the Date of Termination, in either case less the amount of retirement pension
actually to be paid to Executive under the Retirement Program. In computing the
amounts of Executive's retirement pension hereunder and vesting thereunder,
three years shall be added to Executive's actual age and to actual service under
the Retirement Program so that Executive's retirement pension will be the amount
it would have been if Executive had been three years older than Executive
actually were, and had three years more years of service than Executive actually
had, on the Date of Termination.

                                       (B)  If for any reason, the retirement
benefits cannot be paid under the tax-qualified portion of the Retirement
Program, the Company shall provide such benefits to Executive through the
purchase, and delivery to Executive, of a non-qualified annuity from an
insurance company, or Executive may elect to receive a lump sum payment for the
benefits.

                        (iii)     FINANCIAL COUNSELING. The Company shall,
within 60 days of the Date of Termination, make available to Executive financial
counseling, tax counseling and tax preparation services. Executive may select
the organization that will provide such services.

                                      -12-

<PAGE>

However, the Company's obligation to provide Executive benefits under this
subparagraph (vi) shall be limited to $10,000. The Company shall provide to
Executive any information Executive request regarding Executive's personal and
financial situation that Executive wish to provide to the financial counseling
firm in order for the firm to provide the counseling services required by this
subparagraph (vi).

                        (iv)      SEVERANCE PAYMENT. Upon a Change of Control,
the Company shall pay the Severance Payment to Executive not later than the
fifth day following the Date of Termination.

                        (v)       NO REDUCTION IN SEVERANCE PAYMENT. The
Severance Payment shall not be reduced regardless of whether the can properly
deduct amounts paid pursuant to Code section 280G.

                        (vi)      GROSS UP PAYMENT (A) If it shall be determined
that a Payment would be subject to an Excise Tax, then Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that, after payment by Executive of Income Tax and Excise Tax imposed upon
the Gross-Up Payment, Executive shall retain an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payment. Such payment shall be made as
soon as practicable.

                                       (B)  All determinations required to be
made hereunder, including whether a Gross-Up Payment is required and the amount
of such Gross-Up Payment and the assumptions to be utilized in arriving at such
determination, shall be made by the public accounting firm that is retained by
the Company as of the date immediately before a Change of Control of the Company
(the "Accounting Firm") which shall provide detailed supporting calculations
both to the Company and to Executive within fifteen (15) business days of the
receipt of notice from Executive that there has been a Payment, or such earlier
time as is requested by the Company (collectively, the "Determination"). If the
Accounting Firm is serving as accountant or auditor for the individual, entity
or group effecting a Change of Control of the Company, Executive may appoint
another nationally recognized public accounting firm to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall
be borne solely by the Company. Any Gross-Up Payment, as determined hereunder
shall be paid by the Company to Executive within ten (10) days of the
Determination. If the Accounting Firm determines that no Excise Tax is payable
by Executive, Executive may request the Accounting Firm to furnish Executive
with a written opinion that failure to report the Excise Tax on Executive's
applicable federal income tax return would not result in the imposition of a
negligence or similar penalty. The Determination by the Accounting Firm shall be
binding upon the Company and Executive. As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the Determination, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made ("Underpayment"), consistent with the calculations
required to be made hereunder. If the Company exhausts its remedies hereunder,
and Executive thereafter is required to make payment of any Excise Tax or Income
Tax, the Accounting Firm shall determine the amount of

                                      -13-

<PAGE>

the Underpayment that has occurred and any such Underpayment shall be promptly
paid by the Company to or for Executive's benefit.

                                       (C)  Executive shall notify the Company
in writing of any claim by the Internal Revenue Service that, if successful,
would require the payment by the Company of the Gross-Up Payment or the
Underpayment. Such notification shall be given as soon as practicable but no
later than ten (10) business days after Executive is informed in writing of such
claim and shall apprise the Company of the nature of such claim and the date on
which such claim is requested to be paid. Executive shall not pay such claim
prior to the expiration of the 30-day period following the date on which
Executive give such notice to the Company (or such shorter period ending on the
date that any payment of taxes with respect to such claim is due). If the
Company notifies Executive in writing prior to the expiration of such period
that it desires to contest such claim, Executive shall:

                                            (1)  give the Company any
information reasonably requested by the Company relating to such claim,

                                            (2)  take such action in connection
with contesting such claim as the Company shall reasonably request in writing
from time to time, including, without limitation, accepting legal representation
with respect to such claim by an attorney reasonably selected by the Company,

                                            (3)  cooperate with the Company in
good faith in order effectively to contest such claim, and

                                            (4)  permit the Company to
participate in any proceeding relating to such claim;

PROVIDED, HOWEVER, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold Executive harmless, on an
after-tax basis, for any Excise Tax or Income Tax imposed as a result of such
representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this subparagraph (ix)(D), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forego any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and Executive agree to prosecute
such contest to a determination before any administrative tribunal, in a court
of initial jurisdiction and in one or more appellate courts, as the Company
shall determine; provided further, that if the Company directs Executive to pay
such claim and sue for a refund, the Company shall advance the amount of such
payment to Executive on an interest-free basis and shall indemnify and hold
Executive harmless, on an after-tax basis, from any Excise Tax or Income Tax
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and provided further, that any extension of the statute
of limitations relating to payment of taxes for Executive's taxable year with
respect to which such contested amount is claimed to be due is limited solely to
such contested amount. Furthermore, the Company's control of the contest shall
be limited to issues with respect to which a Gross-Up

                                      -14-

<PAGE>

Payment would be payable hereunder and Executive shall be entitled to settle or
contest, as the case may be, any other issue raised by the Internal Revenue
Service or any other taxing authority.

                                            (D)  If, after the receipt by
Executive of an amount advanced by the Company, Executive become entitled to
receive, and receive, any refund with respect to such claim, Executive shall
(subject to the Company's complying with the requirements hereof) promptly pay
to the Company the amount of such refund (together with any interest paid or
credited thereon after taxes applicable thereto). If, after the receipt by
Executive of an amount advanced by the Company, a determination is made that
Executive shall not be entitled to any refund with respect to such claims and
the Company does not notify Executive in writing of its intent to contest such
denial of refund prior to the expiration of thirty (30) days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid.

                        (vii)     VESTING. Upon a Change of Control, all
incentive compensation awards, whether stock options, restricted stock or
otherwise, which have not previously vested, shall automatically be deemed to
have vested and Executive may exercise such awards in accordance with the terms
and conditions of the award as if Executive were still employed by the Company.

                        (viii)    CONSULTANCY ENGAGEMENT. (A) Upon the
occurrence of a Change of Control and provision of Notice of Termination by the
Executive, the Company may elect to require Executive to provide consulting
services for a six (6) month period commencing the date of such election. Such
election shall be made by the Company's provision to Executive of written notice
made no later than thirty (30) days after the receipt of any Notice of
Termination by the Executive.

                                       (B)  If such election is made, Executive
agrees to accept such engagement, in accordance with the following terms and
conditions: Executive shall be available to render such advisory and
consultative services up to thirty five (35) hours per week, but no more than
120 hours in any calendar month during the Term. Such services will be performed
during normal business hours, Monday through Friday, national and New York State
holidays excepted, and subject to reasonable absences for vacation and personal
reasons (with respect to any particular week). No more than ten (10) days away
from the New York metropolitan area, including travel, shall be required in any
calendar month.

                                       (C)  As consideration for the Executive's
services hereunder, pursuant to this Agreement, the Company shall pay Executive
a Consulting Fee equal to 125% of the Base Salary in effect immediately before
the Change of Control and 125% of Bonus Award for the prior fiscal year pro
rated for the six month term and paid on a semi-monthly basis in accordance with
regular payroll practices prior to the Change of Control. Such fee shall be paid
without regard to the number of hours of services actually provided pursuant to
the terms hereof if the Company does not request the Executive to provide the
maximum number of hours.

                                      -15-

<PAGE>

                                       (D)  The Company shall supply Executive
with all materials which the Executive may reasonably require and shall
reimburse Executive for any reasonable out-of-pocket expenses incurred in
providing services, including, but not limited to, first class travel if
services are required to be provided outside of New York State.

                                       (E)  Executive shall be indemnified by
the Company against reasonable expenses, including attorney's fees, actually and
necessarily incurred by him in connection with the defense of any action, suit,
investigation or proceeding or similar legal activity, regardless of whether
criminal, civil, administrative or investigative in nature, to which he is made
a party by reason of his then providing or having provided services to the
Company hereunder.

                                       (F)  The Non-Competition period set forth
in Section 4.3 hereof shall commence on the last date of employment of Executive
(as specified in the Notice of Termination), regardless of whether the Company
exercises its option hereunder.

                        (ix)      NO DUTY TO MITIGATE. Executive shall not be
required to mitigate the amount of any payment provided for hereunder by seeking
other employment or otherwise, nor shall the amount of any payment or benefit
hereunder be reduced by any compensation earned by Executive as the result of
employment by another employer or by retirement benefits after the Date of
Termination, or otherwise; provided, however, should Executive become reemployed
in a job which (a) offers medical plan benefits which are equal to or greater
than the medical plan benefits provided to Executive under subparagraph
2(a)(iii), and (b) such medical plan benefits are offered to Executive at no
cost, Executive shall no longer be eligible to receive medical plan benefits
under this Agreement.

or indirect, by purchase, merger, reorganization, consolidation, acquisition of
assets or stock, liquidation, or otherwise), by agreement in form and substance
reasonably satisfactory to Executive, to assume performance of this Agreement in
the same manner that the Company would have been required to perform this
Agreement if no such succession had taken place. Regardless of whether such
agreement is executed, this Agreement shall be binding upon any successor of the
Company in accordance with the operation of law.

records and information, including, but not limited to, information relating to
(i) any Intellectual Property or (ii) the Company's business practices,
finances, developments, customers, affairs, marketing or purchasing strategy or
other secret information (collectively, clauses (i) and (ii) of this Section
4.2(a) are referred to as the "Confidential Material").

                      (b) All Confidential Material shall be disclosed to
Executive in confidence. Except in performing his duties hereunder, Executive
shall not, during the Term and at all times thereafter, disclose or use any
Confidential Material other than for Company purposes.

                      (c) All records, files, drawings, documents, equipment and
other tangible items containing Confidential Material shall be the Company's
exclusive property, and, upon termination of this Agreement, or whenever
requested by the Company, Executive shall promptly deliver to the Company all of
the Confidential Material (and copies thereof) that may be in Executive's
possession or control. The Company hereby represents and warrants that it shall
give custody of such Confidential Material to a escrow agent, with terms
acceptable to both the Company and the Executive, for a three-year period at an
annual cost not to exceed $3,000.

                      (d) The foregoing restrictions shall not apply if (i) such
Confidential Material has been publicly disclosed (not due to a breach by
Executive of his obligations hereunder or by breach of any other person of a
fiduciary or confidential obligation to the Company) or (ii) Executive is
required to disclose Confidential Material by or to any court of competent
jurisdiction or any governmental or quasi-governmental agency, authority or
instrumentality of competent jurisdiction; PROVIDED, HOWEVER, that Executive
shall, prior to any such disclosure, immediately notify the Company of such
requirement; PROVIDED, FURTHER, that the Company shall have the right, at its
expense, to object to such disclosures and to seek

                                      -8-

confidential treatment of any Confidential Material to be so disclosed on such
terms as it shall determine.

                  4.3 NON-COMPETITION. (a) The Executive shall not, during the
Term, Control any Person which is engaged, directly or indirectly, or
Participate in any business that is competitive with the Company's business of
developing, operating or expanding a facilities-based telecommunications voice
or data network within any country in any European Union member state,
Switzerland or any country (excluding the Americas) in which the Company
currently has a switch or point of presence for either origination or
termination of voice or data transmissions or in which the Company is so engaged
in business or proposes to be so engaged in business in accordance with its
strategic business plan current at the time of the Termination (including the
solicitation of any customer of the Company on behalf of any competitor or any
other business, directly, indirectly on behalf of himself or any other Person)
(collectively, "Competitive Activities"); PROVIDED, HOWEVER, that nothing in
this Agreement shall preclude Executive from owning less than 5% of any class of
publicly traded equity of any Person engaged in any Competitive Activity.
Notwithstanding the immediately preceding sentence, if the Company has ceased to
so provide such services within any such country at the time of Executive's
Termination (or any time thereafter), the covenant set forth in the immediately
preceding sentence shall no longer be applicable to such any such business in
such country.

                      (b) Upon any Termination, the Executive shall not, for
himself or any third party, directly or indirectly, for a period of one-year
following the date of such Termination engage in Competitive Activities.

                4.4   EXECUTIVE INVENTIONS AND IDEAS.

                      (a) Executive hereby agrees to assign to the Company,
without further consideration, his entire right, title and interest (within the
United States and all foreign jurisdictions), to any Intellectual Property
created, conceived, developed or reduced to practice by Executive (alone or with
others), free and clear of any lien or encumbrance. If any Intellectual Property
shall be deemed patentable or otherwise registrable, Executive shall assist the
Company (at its expense) in obtaining letters patent or other applicable
registration therein and shall execute all documents and do all things
(including testifying at the Company's expense) necessary or appropriate to
obtain letters patent or other applicable registration therein and to vest in
the Company, or any affiliate specified by the Board.

                      (b) Should the Company be unable to secure Executive's
signature on any document necessary to apply for, prosecute, obtain or enforce
any patent, copyright or other right or protection relating to any Intellectual
Property, whether due to Executive's Disability or other reason, Executive
hereby irrevocably designates and appoints the Company and each of its duly
authorized officers and agents as Executive's agent and attorney-in-fact to act
for and on Executive's behalf and stead and to execute and file any such
document and to do all other lawfully permitted acts to further the prosecution,
issuance and other enforcement of patents, copyrights or other rights or
protections with the same effect as if executed and delivered by Executive.

                  4.5 ENFORCEMENT.

                      (a) Executive acknowledges that violation of any covenant
or agreement set forth in this Article IV would cause the Company irreparable
damage for which the Company cannot be reasonably compensated in damages in an
action at law, and, therefore, upon any breach by Executive of this Article IV,
the Company shall be entitled to make application to a court of competent
jurisdiction for equitable relief by way of injunction or otherwise (without
being required to post a bond). This provision shall not, however, be construed
as a waiver of any of the rights which the Company may have for damages, and all
of the Company's rights and remedies shall be unrestricted.

                      (b) If any provision of this Agreement, or application
thereof to any person, place or circumstance, shall be held by a court of
competent jurisdiction or be found in an arbitration proceeding to be invalid,
unenforceable or void, the remainder of this Agreement and such provisions as
applied to any other person, place and circumstance shall remain in full force
and effect. It is the intention of the parties hereto that the covenants
contained herein shall be enforced to the maximum extent (but no greater extent)
in time, area, and degree of participation as is permitted by the law of the
jurisdiction whose law is found to be applicable to the acts allegedly in breach
of this agreement, and the parties hereby agree that the court making any such
determination shall have the power to so reform the Agreement.

                      (c) The Executive understands that the provisions of this
Article IV may limit his ability to earn a livelihood in a business similar to
the business of the Company but nevertheless agrees and hereby acknowledges that
(i) such provisions do not impose a greater restraint than is necessary to
protect the goodwill or other business interests of the Company; (ii) such
provisions contain reasonable limitations as to time and the scope of activity
to be restrained; and (iii) the consideration provided under this Agreement,
including, without limitation, any amounts or benefits provided under Article V
hereof, is sufficient to compensate Executive for the restrictions contained in
this Article IV. In consideration of the foregoing and in light of Executive's
education, skills and abilities, Executive agrees that he will not assert, and
it should not be considered, that any provisions of this Article IV prevented
him from earning a living or otherwise are void, voidable or unenforceable or
should be voided or held unenforceable.

                      (d) Each of the covenants of this Article IV is given by
Executive as part of the consideration for this Agreement and as an inducement
to the Company to enter into this Agreement and accept the obligations
hereunder.

                                   TERMINATION

                  5.1 TERMINATION OF AGREEMENT. Except as otherwise provided,
this Agreement shall become invalid upon any Termination of employment.

<PAGE>

                  5.2 PROCEDURES APPLICABLE TO TERMINATION.

                      (a) TERMINATION FOR CAUSE. The Executive may be terminated
for Cause, upon prior written notice from the Board to Executive for termination
for Cause provided that Executive, with his counsel, shall have had the
opportunity during such period to be heard at a meeting of the Board concerning
such determination. The Executive's right to be heard in connection with a
Termination shall not otherwise effect the rights and obligations hereunder.

                      (b) RESIGNATION FOR GOOD REASON. The Executive may
terminate his employment for Good Reason, upon prior written notice from
Executive to the Board of his intent to resign for Good Reason provided that
Executive, with his counsel, shall have met with the Board, if requested by the
Board, during such period with respect to his intent to resign. The Executive's
obligation to be heard in connection with a Termination shall not otherwise
effect the rights and obligations hereunder.

                      (c) TERMINATION WITHOUT CAUSE. The Executive may be
terminated without Cause, upon prior written notice from the Board to Executive,
by a vote of the Board, provided that Executive, with his counsel, shall have
had the opportunity during such period to be heard at a meeting of the Board
with respect to such determination. The Executive's right to be heard in
connection with a Termination shall not otherwise effect the rights and
obligations hereunder.

                      (d) TERMINATION FOR DISABILITY. The Executive may be
terminated for Disability, upon prior written notice from the Board to
Executive, by a vote of the Board, provided that Executive, with his counsel,
shall have had the opportunity during such period to be heard at a meeting of
the Board with respect to such determination. The Executive's right to be heard
in connection with a Termination shall not otherwise effect the rights and
obligations hereunder.

                      (e) TERMINATION UPON A CHANGE OF CONTROL. Upon the
occurence of any transaction resulting in a Change of Control, the Executive may
terminate his employment by providing written notice of such termination to the
Company within 60 days of the effective date of such Change of Control.

                  5.3 OBLIGATIONS OF THE COMPANY UPON TERMINATION.

                      (a) ALL TERMINATIONS. Upon any Termination, the Company
shall pay to Executive, or, upon Executive's Disability, to his heirs, estate or
legal representatives, as the case may be, the following:

                          (i) all Accrued Obligations in a lump sum within 10
days after the date of Termination; and

                          (ii) all benefits accrued by Executive as of the date
of Termination under all qualified and nonqualified retirement, pension, profit
sharing and similar plans of the Company to such extent, in such manner and at
such time as are provided under the terms of such plans and arrangements.

                                      -11-
<PAGE>

                      (b) TERMINATION WITHOUT CAUSE OR RESIGNATION FOR GOOD
REASON. If the Board terminates Executive's employment without Cause (excluding
Termination because of Disability), or if Executive resigns for Good Reason, in
addition to the amounts payable under Section 5.3(a) hereof:

                          (i) The Company shall pay Executive the Severance
Payment in a lump sum within 10 days after the date of Termination; and

                          (ii) The Company shall continue all benefits coverage
of Executive and any dependents then provided under its benefit plans or
policies for the unexpired portion of the Term.

                      (c) TERMINATION FOR CAUSE OR RESIGNATION WITHOUT GOOD
REASON. If the Board terminates Executive's employment for Cause, or if
Executive resigns without Good Reason, Executive shall only be entitled to the
amounts payable under Section 5.3(a) hereof.

                      (d) TERMINATION FOR DISABILITY. Upon Termination of
Executive because of a Disability, in addition to the amounts payable under
Section 5.3(a) hereof, the Company shall pay the aggregate Disability Payment
for the greater of (i) three years (in accordance with the Company's regular
payroll practices then in existence) and (ii) the period covered by any
Disability Plan.

                      (e) TERMINATION UPON A CHANGE OF CONTROL. If Executive
provides Notice of Termination of employment within 60 days of the date that a
Change of Control occurs, in addition to the amounts payable under Section
5.3(a) hereof, Executive shall be entitled to the benefits provided below,
without regard to any contrary provision of any plan:

                          (i) INSURANCE COVERAGE. The Company shall arrange to
provide Executive (and dependents, if applicable) with life, disability (to the
extent available at standard commercial rates), accident, dental and medical
benefits substantially equivalent to those which Executive receives, or was
entitled to receive, from the Company immediately before a Change of Control of
the Company. Such benefits shall be provided for the longer of (x) thirty six
(36) months after such Date of Termination or (y) the period during which such
benefits would have been provided to Executive, as a terminated employee, under
the applicable life, disability, accident, dental and medical plans in effect
immediately before a Change of Control of the Company (except that after a
period of thirty six (36) months such benefits shall be provided on the same
financial terms and conditions as provided for under the respective plans).

                          Should it be determined that any of the medical
benefits to be provided to Executive (and dependents, if applicable) under this
subparagraph could be included in Executive's gross income for federal, state or
local tax purposes, then the following shall apply:

                               (A) If Executive is retirement eligible on
Executive's Date of Termination, then Executive shall participate in the
Company's medical benefit plans as if Executive retired from the Company on
Executive's Date of Termination, except that the Company shall provide such
medical coverage at no cost to Executive for three

                                      -12-
<PAGE>

(3) years following Executive's Date of Termination. Thereafter, Executive shall
participate therein on the same terms as other retired employees; and

                               (B) If Executive is not eligible for retirement
upon Executive's Date of Termination, Executive will no longer continue to
participate in the Company's medical benefit plans and (i) the Company shall
provide Executive with a cash payment in an amount equal to the amount required
by Executive to pay for coverage under COBRA for the first eighteen (18) months
following Executive's loss of medical coverage, and thereafter, (ii) the Company
shall, for the subsequent eighteen (18) months, purchase for Executive, at its
cost, a policy of medical insurance providing benefits substantially similar to
the benefits Executive would have received under the Company's medical benefit
plans.

                          (ii) RETIREMENT BENEFITS. (A) The Company shall pay
Executive, at the time Executive is entitled to be paid a retirement pension
under the Retirement Program, a retirement pension equal to the greater of (x)
an amount computed in accordance with the terms of any Retirement Program in
effect immediately before the Change of Control, or (y) an amount computed in
accordance with the terms of the Retirement Program in effect immediately before
the Date of Termination, in either case less the amount of retirement pension
actually to be paid to Executive under the Retirement Program. In computing the
amounts of Executive's retirement pension hereunder and vesting thereunder,
three years shall be added to Executive's actual age and to actual service under
the Retirement Program so that Executive's retirement pension will be the amount
it would have been if Executive had been three years older than Executive
actually were, and had three years more years of service than Executive actually
had, on the Date of Termination.

                               (B) If for any reason, the retirement benefits
cannot be paid under the tax-qualified portion of the Retirement Program, the
Company shall provide such benefits to Executive through the purchase, and
delivery to Executive, of a non-qualified annuity from an insurance company, or
Executive may elect to receive a lump sum payment for the benefits.

                          (iii) FINANCIAL COUNSELING. The Company shall, within
60 days of the Date of Termination, make available to Executive financial
counseling, tax counseling and tax preparation services. Executive may select
the organization that will provide such services. However, the Company's
obligation to provide Executive benefits under this subparagraph (iii) shall be
limited to $10,000. The Company shall provide to Executive any information
Executive request regarding Executive's personal and financial situation that
Executive wish to provide to the financial counseling firm in order for the firm
to provide the counseling services required by this subparagraph (iii).

                          (iv) SEVERANCE PAYMENT. Upon a Change of Control, the
Company shall pay the Severance Payment to Executive not later than the fifth
day following the Date of Termination.

                          (v) NO REDUCTION IN SEVERANCE PAYMENT. The Severance
Payment shall not be reduced regardless of whether the Company can properly
deduct amounts paid pursuant to Code section 280G.

                                      -13-
<PAGE>

                          (vi) GROSS UP PAYMENT (A) If it shall be determined
that a Payment would be subject to an Excise Tax, then Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount
such that, after payment by Executive of Income Tax and Excise Tax imposed upon
the Gross-Up Payment, Executive shall retain an amount of the Gross-Up Payment
equal to the Excise Tax imposed upon the Payment. Such payment shall be made as
soon as practicable.

                               (B) All determinations required to be made
hereunder, including whether a Gross-Up Payment is required and the amount of
such Gross-Up Payment and the assumptions to be utilized in arriving at such
determination, shall be made by the public accounting firm that is retained by
the Company as of the date immediately before a Change of Control of the Company
(the "Accounting Firm") which shall provide detailed supporting calculations
both to the Company and to Executive within fifteen (15) business days of the
receipt of notice from Executive that there has been a Payment, or such earlier
time as is requested by the Company (collectively, the "Determination"). If the
Accounting Firm is serving as accountant or auditor for the individual, entity
or group effecting a Change of Control of the Company, Executive may appoint
another nationally recognized public accounting firm to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall
be borne solely by the Company. Any Gross-Up Payment, as determined hereunder
shall be paid by the Company to Executive within ten (10) days of the
Determination. If the Accounting Firm determines that no Excise Tax is payable
by Executive, Executive may request the Accounting Firm to furnish Executive
with a written opinion that failure to report the Excise Tax on Executive's
applicable federal income tax return would not result in the imposition of a
negligence or similar penalty. The Determination by the Accounting Firm shall be
binding upon the Company and Executive. As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the Determination, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made ("Underpayment"), consistent with the calculations
required to be made hereunder. If the Company exhausts its remedies hereunder,
and Executive thereafter is required to make payment of any Excise Tax or Income
Tax, the Accounting Firm shall determine the amount of the Underpayment that has
occurred and any such Underpayment shall be promptly paid by the Company to or
for Executive's benefit.

                          (C) Executive shall notify the Company in writing of
any claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of the Gross-Up Payment or the Underpayment. Such
notification shall be given as soon as practicable but no later than ten (10)
business days after Executive is informed in writing of such claim and shall
apprise the Company of the nature of such claim and the date on which such claim
is requested to be paid. Executive shall not pay such claim prior to the
expiration of the 30-day period following the date on which Executive give such
notice to the Company (or such shorter period ending on the date that any
payment of taxes with respect to such claim is due). If the Company notifies
Executive in writing prior to the expiration of such period that it desires to
contest such claim, Executive shall:

                                      -14-
<PAGE>

                              (1) give the Company any information reasonably
requested by the Company relating to such claim,

                              (2) take such action in connection with contesting
such claim as the Company shall reasonably request in writing from time to time,
including, without limitation, accepting legal representation with respect to
such claim by an attorney reasonably selected by the Company,

                              (3) cooperate with the Company in good faith in
order effectively to contest such claim, and

                              (4) permit the Company to participate in any
proceeding relating to such claim;

PROVIDED, HOWEVER, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold Executive harmless, on an
after-tax basis, for any Excise Tax or Income Tax imposed as a result of such
representation and payment of costs and expenses. Without limitation on the
foregoing provisions of this subparagraph (vi)(C), the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may
pursue or forego any and all administrative appeals, proceedings, hearings and
conferences with the taxing authority in respect of such claim and may, at its
sole option, either direct Executive to pay the tax claimed and sue for a refund
or contest the claim in any permissible manner, and Executive agrees to
prosecute such contest to a determination before any administrative tribunal, in
a court of initial jurisdiction and in one or more appellate courts, as the
Company shall determine; PROVIDED FURTHER, that if the Company directs Executive
to pay such claim and sue for a refund, the Company shall advance the amount of
such payment to Executive on an interest-free basis and shall indemnify and hold
Executive harmless, on an after-tax basis, from any Excise Tax or Income Tax
imposed with respect to such advance or with respect to any imputed income with
respect to such advance; and PROVIDED FURTHER, that any extension of the statute
of limitations relating to payment of taxes for Executive's taxable year with
respect to which such contested amount is claimed to be due is limited solely to
such contested amount. Furthermore, the Company's control of the contest shall
be limited to issues with respect to which a Gross-Up Payment would be payable
hereunder and Executive shall be entitled to settle or contest, as the case may
be, any other issue raised by the Internal Revenue Service or any other taxing
authority.

                              (D) If, after the receipt by Executive of an
amount advanced by the Company, Executive become entitled to receive, and
receive, any refund with respect to such claim, Executive shall (subject to the
Company's complying with the requirements hereof) promptly pay to the Company
the amount of such refund (together with any interest paid or credited thereon
after taxes applicable thereto). If, after the receipt by Executive of an amount
advanced by the Company, a determination is made that Executive shall not be
entitled to any refund with respect to such claims and the Company does not
notify Executive in writing of its intent to contest such denial of refund prior
to the expiration of thirty (30) days after such determination, then such
advance shall be forgiven and shall not be required to be repaid.

<PAGE>

                              (vii) VESTING. Upon a Change of Control, all
incentive compensation awards, whether stock options, restricted stock or
otherwise, which have not previously vested, shall automatically be deemed to
have vested and Executive may exercise such awards in accordance with the terms
and conditions of the award as if Executive were still employed by the Company.

                              (viii) CONSULTANCY ENGAGEMENT. (A) Upon the
occurrence of a Change of Control and provision of Notice of Termination by the
Executive, the Company may elect to require Executive to provide consulting
services for a six- (6) month period commencing the date of such election. Such
election shall be made by the Company's provision to Executive of written notice
made no later than thirty (30) days after the receipt of any Notice of
Termination by the Executive.

                                     (B) If such election is made, Executive
agrees to accept such engagement, in accordance with the following terms and
conditions: Executive shall be available to render such advisory and
consultative services up to thirty five (35) hours per week, but no more than
120 hours in any calendar month during the Term. Such services will be performed
during normal business hours, Monday through Friday, national and New York State
holidays excepted, and subject to reasonable absences for vacation and personal
reasons (with respect to any particular week). No more than ten (10) days away
from the New York metropolitan area, including travel, shall be required in any
calendar month.

                                     (C) As consideration for Executive's
services hereunder, the Company shall pay Executive a Consulting Fee equal to
125% of the Base Salary in effect immediately before the Change of Control and
125% of Bonus Award for the prior fiscal year pro rated for the six month term
and paid on a semi-monthly basis in accordance with regular payroll practices
prior to the Change of Control. Such fee shall be paid without regard to the
number of hours of services actually provided pursuant to the terms hereof if
the Company does not request the Executive to provide the maximum number of
hours.

                                     (D) The Company shall supply Executive with
all materials which the Executive may reasonably require and shall reimburse
Executive for any reasonable out-of-pocket expenses incurred in providing
services, including, but not limited to, first class travel if services are
required to be provided outside of New York State.

                                     (E) Executive shall be indemnified by the
Company against reasonable expenses, including attorney's fees, actually and
necessarily incurred by him in connection with the defense of any action, suit,
investigation or proceeding or similar legal activity, regardless of whether
criminal, civil, administrative or investigative in nature, to which he is made
a party by reason of his then providing or having provided services to the
Company hereunder.

                                     (F) The Non-Competition period set forth in
Section 4.3 hereof shall commence on the last date of employment of Executive
(as specified in the Notice of Termination), regardless of whether the Company
exercises its option hereunder.

                                      -16-
<PAGE>

                              (ix) NO DUTY TO MITIGATE. Executive shall not be
required to mitigate the amount of any payment provided for hereunder by seeking
other employment or otherwise, nor shall the amount of any payment or benefit
hereunder be reduced by any compensation earned by Executive as the result of
employment by another employer or by retirement benefits after the Date of
Termination, or otherwise; provided, however, should Executive become reemployed
in a job which (a) offers medical plan benefits which are equal to or greater
than the medical plan benefits provided to Executive under subparagraph 3.4(a),
and (b) such medical plan benefits are offered to Executive at no cost,
Executive shall no longer be eligible to receive medical plan benefits under
this Agreement.
