                              EMPLOYMENT AGREEMENT

    This EMPLOYMENT AGREEMENT (the "Agreement"), dated as of October 9, 2000, is
entered into by and between Metromedia Fiber Network, Inc. ("MFN") and
SiteSmith, Inc., a Delaware corporation (formerly known as SiteBrigade, Inc.)
("Company"), on the one hand, and Robert Ryan ("Executive"), on the other hand.

    WHEREAS, MFN and Company that Executive be employed as the Senior Vice
President of Operations of Company, and Executive desires to be so employed by
Company, on the terms and conditions herein provided.

    NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements of the parties herein contained, the parties hereto
agree as follows:

    1.  Employment.

        (a) Title; Reporting.  During the Term (as hereinafter defined), Company
    shall employ Executive, and Executive shall render services to Company as
    the Senior Vice President of Operations of Company and shall report to the
    Chief Executive Officer of the Company.

        (b) Duties.  Executive shall have such duties as are consistent with the
    position of Senior Vice President of Operations.

        (c) No Other Employment.  Executive shall devote his full and exclusive
    business time and best efforts to the performance of his duties under this
    Employment Agreement and shall perform them faithfully, diligently and
    competently.

        (d) No Conflict.  Executive represents and warrants that neither the
    execution by him of this Agreement nor the performance by him of his duties
    and obligations hereunder will conflict with or violate any agreement to
    which he is a party or by which he is bound.

        (e) Commencement Date.  This Agreement amends and supercedes the earlier
    Change of Control Agreement between Executive and Company of October 1,
    1999, PROVIDED, HOWEVER, that this Agreement shall become effective as of
    the effective date of the merger between Aqueduct Acquisition Corp., a
    wholly-owned subsidiary of MFN ("Merger Sub"), and the Company (the
    "Commencement Date"). The earlier Change of Control Agreement will continue
    in effect until the effective date of the merger.

        (f) Place of Employment.  Executive's office will be in Santa Clara,
    California; PROVIDED, HOWEVER, that Executive shall travel for business
    purposes or perform services at the Company's other locations as required
    from time to time.

    2.  Term of Employment.  Executive agrees to work for, and remain employed
by, the Company for a period of two years, that is, until September 30, 2002.
Until this date, Executive may only resign his employment for Good Cause, as
defined herein. The Company may terminate Executive's employment at any time for
any reason, with or without cause. If Executive's employment continues after two
years, then Executive's employment with the Company shall at all times
thereafter be "at will," which means that either the Executive or the Company
may terminate the Executive's employment at any time for any or no reason, with
or Without Cause (as defined below) by giving notice in writing. Executive's
employment shall terminate automatically in the event of his death. The term of
Executive's employment under this Agreement shall commence on the date hereof
and continue until terminated as provided for herewith ("Term").

                                     D-2-1

    3.  Compensation.

        (a) Base Salary.  Company shall pay to Executive throughout the Term an
    annual salary (the "Base Salary") of not less than $225,000 per year,
    payable in accordance with the Company's customary policies. The Base Salary
    will be reviewed at least annually by the Company's Chief Executive Officer
    and Board of Directors and, if appropriate, it will be increased.

        (b) Target Bonus.  For each one year period starting on January 1, 2001,
    Executive shall be eligible to earn an annual discretionary incentive bonus
    equal to at least 40% of his Base Salary ("Target Bonus"). The Target Bonus
    shall be earned based on achievement of objectives to be identified by the
    Company's Chief Executive Officer ("CEO"). The CEO will set objectives
    mutually agreed upon by Executive and the CEO by February 28 of the year in
    question. Target Bonuses payable under this Subsection 3(b) shall be payable
    in accordance with the Company's normal practices and policies no later than
    January 31 of the following year.

    4.  Equity.

        (a) Option Grant.  MFN will grant Executive an option to purchase
    200,000 shares of MFN class A common stock, par value $.01 per share (the
    "Option Shares"), subject to the terms of the Metromedia Fiber
    Network, Inc. 2000 Stock Option Plan and execution of the standard form of
    stock option agreement thereunder (except as necessarily modified to conform
    to the provisions of this Agreement). This Option grant shall be granted
    concurrently with or as soon as reasonably practicable after the
    Commencement Date. The per share exercise price of the Option Shares shall
    be equal to the per share fair market value of the class A common stock on
    the date of grant. The Option Shares shall become exercisable as to 25% of
    the Option Shares upon the one year anniversary of the Commencement Date and
    as to the remaining shares shall vest ratably over each of the next three
    annual anniversaries thereof, such that all of the Option Shares shall be
    vested as of the fourth anniversary of the Commencement Date.

        (b) Company Stock.  On September 15, 1999 Executive purchased 7,200,000
    shares of Company Common Stock at $0.001 a share pursuant to the terms of a
    Common Stock Purchase Agreement ("Purchase Agreement"). A total of 1,350,000
    shares subject to the Purchase Agreement were vested as of the date of
    grant. The remaining shares vested, that is, the Company's repurchase right
    lapsed each month over the course of forty-eight months. On October 1, 1999,
    Executive executed a Change of Control Agreement that provided for, INTER
    ALIA, certain accelerated vesting. Executive will execute the Waiver of
    Accelerated Vesting contained in Exhibit A, attached hereto.

        (c) Registration of Shares.  The Company will take all reasonable steps
    at its cost to register the Executive's Option Shares, as well as all shares
    purchased by Executive under Stock Purchase Agreement, so that the Executive
    can sell any vested shares if he so chooses following the expiration of any
    applicable lock-up period. Other than as set forth in this Subsection 4(c),
    the Company shall be under no obligation to register any of the shares and
    the Company shall not be obligated to register the shares hereunder if so
    doing would cause the Company to violate any applicable laws.

    5.  Benefits.

        (a) General Fringe Benefits.  Executive shall be entitled to participate
    in the life, hospitalization, health, accident and disability insurance
    plans, health programs, pension plans and other benefit and compensation
    plans generally available to senior executives of Company from time to time.

                                     D-2-2
<PAGE>
        (b) Reimbursements.  Company shall pay or reimburse Executive for all
    reasonable expenses actually incurred or paid by Executive during the Term
    in the performance of Executive's duties to Company upon presentation by
    Executive of expense statements or vouchers.

    6.  "Change-in-Control."  In the event of a "change-in-control" at any time
after the Commencement Date, then 50% of the unvested Option Shares, as well as
all shares subject to the Stock Purchase Agreement, immediately shall become
fully vested and exercisable and, where applicable, the Company's repurchase
right will lapse as to such shares, as of the date of the "change-in-control."
For all purposes under this Agreement, "change-in-control" shall mean a sale of
all or substantially all of MFN's or the Company's assets, or any merger or
consolidation of MFN or the Company with or into another corporation other than
a merger or consolidation in which the holders of more than 50% of the shares of
capital stock of MFN or the Company outstanding immediately prior to such
transaction continue to hold directly or indirectly (either by the voting
securities remaining outstanding or by their being converted into voting
securities of the surviving entity) more than 50% of the total voting power
represented by the voting securities of MFN or the Company, or such surviving
entity, outstanding immediately after such transaction.

    7.  Termination or Resignation of Employment.

        (a) Executive's employment may be terminated at the option of Company by
    notice to Executive (i) for Cause (as hereinafter defined), or (ii) Without
    Cause. Executive may resign his employment for Good Reason at any time prior
    to September 30, 2002 and for any reason at any time thereafter.

        (b) If Company shall terminate Executive's employment hereunder for
    Cause, Executive shall have no right to receive any compensation or benefit
    from Company hereunder on and after the effective date of such notice,
    except for compensation, benefits, and reimbursements that are accrued and
    unpaid as of the date of termination.

        (c) If Company terminates Executive's employment hereunder Without
    Cause, or Executive resigns his employment for Good Reason, at any time
    other than on or within one year after a "change-in-control," Executive
    shall be paid the following for a period equal to the greater of (i) the
    period from the date of termination of employment through September 30,
    2002, or (ii) six months after the date of termination of employment
    (hereafter referred to as the "Severance Period"): (A) his then-current
    annual Base Salary (subject to applicable tax withholding), payable in
    accordance with the Company's normal payroll practices through the Severance
    Period; (B) his Target Bonus at the rate in effect for the period in which
    the termination occurs (as though all milestones or objectives applicable to
    such bonus have been achieved), less all applicable tax withholding, for the
    Severance Period (Executive will be entitled to the full Target Bonus for
    each full annual bonus period falling within the Severance Period, as well
    as a pro rata portion of the Target Bonus for any additional portion of the
    Severance Period); (C) reimbursement for his expenses incurred in continuing
    his medical coverage for himself and his dependents under the Consolidated
    Omnibus Budget Reconciliation act of 1985, as amended ("COBRA") for the
    Severance Period, provided Executive makes a timely election for such
    continued coverage; and (D) Executive's Option shares shall be deemed to
    have vested and become exercisable as if Executive had continued employment
    with the Company through the Severance Period. In addition, the Executive's
    shares of Company Common Stock purchased under the Stock Purchase Agreement
    shall immediately and fully vest, and the Company's right to repurchase as
    to such shares if applicable shall lapse as to all such shares.

        (d) If Company, or a successor to the Company's business as a result of
    a "change-in-control" (as defined in Section 6 above), terminates
    Executive's employment hereunder Without Cause or Executive resigns for Good
    Reason on or within twelve months after a "change-in-control," Executive
    shall be entitled to receive a lump sum payment equal to his then current
    annual Base

                                     D-2-3
<PAGE>
    Salary plus his Target Bonus for the Severance Period (as though all
    milestones or objectives applicable to such bonus have been achieved), less
    all applicable tax withholding (the amount of the Target Bonus will be
    calculated as in Subsection 7(c) above); reimbursement for his expenses
    incurred in continuing his medical coverage for himself and his dependents
    under the Consolidated Omnibus Budget Reconciliation act of 1985, as amended
    ("COBRA") for Severance Period, provided Executive makes a timely election
    for such continued coverage; and Executive's Option shares shall immediately
    and fully vest and become exercisable.

        (e) As used in this Employment Agreement, a termination for "Cause"
    shall mean a good faith determination by the Company that Executive's
    employment be terminated for any of the following reasons: (i) Executive's
    willful failure to perform his duties to the Company, to follow Company
    policy as set forth from time to time, or to follow the legal directives of
    his supervisor, in each case in a manner that results in material damage to
    the Company; (ii) conviction, including by guilty plea or plea of no
    contest, of Executive of a felony or of another crime involving fraud, moral
    turpitude or material loss to the Company; (iii) willful material breach by
    Executive of his affirmative or negative covenants or undertakings
    hereunder, which such breach is not remedied within five (5) business days
    after written notice to Executive thereof (which notice shall be signed by
    the Company CEO or other designated officer of Company and refer to a
    specific breach of this Employment Agreement); (iv) the Executive's willful
    use or unauthorized disclosure of any proprietary information or trade
    secrets of the Company or any other party to whom the Executive owes an
    obligation of nondisclosure as a result of his relationship with the
    Company; or (v) Executive's willful act of fraud, embezzlement, dishonesty
    or other misconduct that materially damages the Company. A termination of
    Executive's employment in any other circumstances or for any other reasons
    will be a termination "Without Cause."

        (f) Resignation by Executive for "Good Reason." A resignation of
    Executive's employment by written notice within six months of any of the
    following events shall be a Resignation for Good Reason:

    (i) a material reduction in the nature or scope of Executive's title,
        authority, powers, stature, duties, or responsibilities hereunder;

    (ii) a reduction of greater than 5% in Executive's Base Salary, Target
         Bonus, benefits and/or incentive payments;

   (iii) a material change in Executive's reporting relationship;

    (iv) a requirement that Executive relocate his principal place of employment
         by more than fifty (50) miles from Santa Clara, California, provided
         such relocation is effected by the Company without his written consent;
         or

    (v) Company's materially breaching its affirmative or negative covenants or
        undertakings hereunder and such breach shall not be remedied within
        fifteen (15) days after notice to Company thereof (which notice shall be
        signed by Executive and refer to a specific breach of this Employment
        Agreement).

    A resignation of employment by Executive for any other reason shall be a
resignation without "Good Reason."

    8.  Limitation on Change of Control Benefits.  In the event that the
acceleration of vesting benefits provided pursuant to this Agreement in
connection with, or as a result of, a Change of Control of the Company
(a) constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code") and (b) but for this
Section, would be subject to the excise tax imposed by Section 4999 of the Code,
then such benefits shall be payable either: (i) in full, or (ii) as to such
lesser amount which would result in no portion of such benefits

                                     D-2-4
<PAGE>
being subject to excise tax under Section 4999 of the Code, whichever of the
foregoing amounts, taking into account the applicable federal, state and local
income taxes and the excise tax imposed by Section 4999, results in the
Executive's receipt on an after-tax basis, of the greatest amount of benefits,
notwithstanding that all or some portion of such benefits may be taxable under
Section 4999 of the Code. Unless the Executive and the Company otherwise agree
in writing, any determination required under this Section 8 shall be made in
writing by the Company's independent public accountants (or if the Company does
not have independent public accountants as such, any other accounting firm
engaged by the Company to prepare its financial statements) (the "Accountants"),
whose determination shall be conclusive and binding upon Executive and the
Company for all purposes. For purposes of making the calculations required by
this Section 8, the Accountants may make reasonable assumptions and
approximations concerning applicable taxes and may relay on reasonable, good
faith interpretations concerning the application of Section 280G and 4999 of the
Code. The Company and the Executive shall furnish to the Accountants such
information and documents as the Accountants may reasonably request in order to
make a determination under this Section 8. The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this Section 8.

    9.  Prohibited Activities.

        (a) Non-Compete Period.  For the purposes of this Employment Agreement,
    the term "Non-Compete Period" shall mean the Term, and if Executive's
    employment is terminated by Company for "Cause" or Executive resigns his
    employment without "Good Reason," an additional period of six months from
    and after the date of termination.

        (b) Non-competition.  During the Non-Compete Period, Executive shall not
    directly or indirectly compete with, be engaged in the business of, be
    employed by, act as a consultant to, or be a director, officer, employee,
    owner or partner of, any person or entity which is engaged in the primary
    business of MFN or the Company at such time and in the territories served by
    MFN or the Company in such business during the Non-Compete Period. However,
    nothing in this Agreement will prevent Executive from accepting speaking or
    presentation engagements in exchange for honoraria or from serving on boards
    of charitable organizations, or from owning no more than two percent (2%) of
    the outstanding equity securities of a corporation whose stock is listed on
    a national stock exchange or the Nasdaq.

        (c) Consideration for Non-Competition Agreement.  Executive specifically
    acknowledges and agrees that the covenant contained in Subsection 9(b)
    hereof is an essential element of the Merger Agreement, dated as of the date
    hereof, (the "Merger Agreement"), by and among MFN, Merger Sub and Company
    and this Agreement and that, but for the agreement of Executive to comply
    with such covenant, MFN would not have entered into the Merger Agreement and
    Company would not have entered into this Agreement.

        (d) Solicitation of Employees.  During the Non-Compete Period, Executive
    shall not directly or indirectly employ, or solicit to leave Company's
    employ, or solicit to join the employ of another person or entity (including
    any such person or entity owned or controlled, directly or indirectly, by
    Executive) any employee of Company or any person who has been such an
    employee during the twelve months preceding Executive's date of termination.

        (e) Confidential Information.  During and at all times subsequent to the
    Term, Executive shall keep secret and shall not exploit or disclose or make
    accessible to any person or entity, except in furtherance of the business of
    Company, and except as may be required by law or legal process, any
    confidential business information of any type that was acquired or developed
    by either Company or any of its subsidiaries or affiliates, or Executive,
    prior to or during the Term. In addition, the term "confidential business
    information" shall not include information which (i) is or becomes generally
    available to the public other than as a result of a disclosure by Executive;
    or

                                     D-2-5
<PAGE>
    (ii) was available to Executive prior to any employment by Company as a
    result of his general business experience.

        (f) Divisibility.  The provisions contained in this Section 9 as to the
    time period and scope of activities restricted shall be deemed divisible, so
    that if any provision contained in this section 9 is determined to be
    invalid or unenforceable, that provision shall be deemed modified so as to
    be valid and enforceable to the full extent lawfully permitted.

        (g) Relief.  Executive acknowledges that the provisions of this
    Section 9 are reasonable and necessary for the protection of Company and
    that Company will be irreparably damaged if such covenants are not
    specifically enforced. Accordingly, it is agreed that Company will be
    entitled to injunctive relief for the purpose of restraining Executive from
    violating such covenants (and no bond or other security shall be required in
    connection therewith), in addition to any other relief to which Company may
    be entitled.

    10.  Indemnification.  Executive has entered into an Indemnification
Agreement with Company, which will continue in full force and effect. Further,
MFN agrees to indemnify Executive to the same extent to which the Company is
obligated to indemnify Executive under the Indemnification Agreement.

    11. Miscellaneous.

        (a) Survival.  The covenants and agreements set forth in this Employment
    Agreement shall survive Executive's termination of employment, irrespective
    of any investigation made by or on behalf of any party.

        (b) Headings.  The section headings of this Employment Agreement are for
    reference purposes only and are to be given no effect in the construction or
    interpretation of this Employment Agreement.

        (c) Assignment.  This Employment Agreement shall not be assignable by
    Executive without the prior written consent of Company, and shall inure to
    the benefit of and be binding upon Executive and his legal representatives.

        (d) Territory.  Executive shall not be required to relocate or render
    services hereunder in any geographic area beyond a radius of fifty
    (50) miles from Santa Clara, California; PROVIDED, HOWEVER, that Executive
    may be required to travel for business purposes from time to time as
    reasonably requested by Company.

        (e) Governing Law.  This Employment Agreement shall be governed by and
    construed in accordance with the law of the State of California applicable
    to agreements made and to be performed in that State, without reference to
    its principles of conflicts of law.

        (f) Notices.  All notices, requests, demands and other communications
    (collectively, "Notices") that are required or may be given under this
    Employment Agreement, shall be in writing, signed by the party or the
    attorney for that party. All Notices shall, except as otherwise specifically
    provided herein to the contrary, be deemed to have been duly given or made:
    if by hand, immediately upon delivery; if by telecopier or similar device,
    immediately upon sending, provided notice is sent on a business day during

following the date of death.

     7.   COVENANTS AND RESTRICTIONS.

          (a)  For a period of one (1) year following the termination of this
Agreement (the "Non-Compete Period"), the Executive shall not, directly or
indirectly, engage in, own, manage, operate, assist, join or control, or
participate in the ownership, management, operation or control of any Restricted
Enterprise (other than the Company or its affiliates), which engages or plans to
engage in a Restricted Enterprise anywhere in the United States, whether as a
director, officer, executive, agent, consultant, shareholder, partner, owner,
independent contractor or otherwise. Notwithstanding the foregoing, these
restrictions shall not prevent the Executive from earning his livelihood during
the Non-Compete Period. As used herein, a "Restricted Enterprise" shall be any
activity that competes with the business of the Company, including the business
of Intrex, in any line of business that constitutes 5% or more of the net sales
of the Company or Intrex on the date of termination of this Agreement.
Notwithstanding the foregoing, the provisions of this Section 7(a) shall not
apply if Executive's employment is terminated pursuant to Section 11(b) or
Section 12 of this Agreement.

                                       3
<PAGE>

          (b)  The Executive agrees that he shall not divulge to others, nor
shall he use to the detriment of the Company or in any business competitive with
or similar to any business engaged in by the Company or any of its subsidiary or
affiliated companies, at any time during his employment with the Company or
thereafter, any Confidential Information obtained by him during the course of
his employment with the Company. For the purpose of this Agreement,
"Confidential Information" means any and all information developed by or for or
processed by the Company or its affiliates of which the Executive has knowledge
during the term of his employment that is (1) not generally known in any
industry in which the Company or its affiliates does business during the
Non-Compete Period or (2) not publicly available and treated as confidential.

          (c)  During the Non-Compete Period, the Executive will neither
solicit, hire or seek to solicit or hire any of the Company's personnel in any
capacity whatsoever nor shall Executive induce or attempt to induce any of the
Company's personnel to leave the employ of the Company to work for Executive or
otherwise.

     8.   REMEDIES. The Executive acknowledges that his breach of any of the
restrictive covenants contained in Section 7 herein may cause irreparable damage
to the Company for which remedies of law would be inadequate. Accordingly, the
Executive breaches or threatens to breach any of the provisions of Section 7,
the Company shall be entitled to appropriate injunctive relief, including,
without limitation, preliminary and permanent injunctions, in any court of
competent jurisdiction, restraining Executive from taking any action prohibited
hereby. This remedy shall be in addition to all other remedies available to the
Company at law or equity. If any portion of Section 7 is adjudicated to be
invalid or unenforceable, Section 7 shall be deemed amended to delete therefrom
the points so adjudicated, such deletion to apply only with respect to the
operation of Section 7 in the jurisdiction in which the adjudication is made.

     9.   INDEMNIFICATION. The Company hereby indemnifies and holds the
Executive harmless for any and all expenses (including legal fees) or losses
incurred by him in connection with the performance of his duties under this
Agreement.

     10.  PRIOR AGREEMENTS. The Executive represents that he is not now under
any written agreement, nor has he previously, at any time, entered into any
written agreement with any person, firm or corporation, which would or could in
any manner preclude or prevent him from giving freely and the Company receiving
the exclusive benefit of his services.

     11.  TERMINATION PROVISIONS.

          (a)  In addition to, and not in lieu of, the termination provisions
set forth in Section 6 herein, the employment of the Executive hereunder may be
terminated by the Company prior to the termination date of the initial term or
any renewal term thereafter (as set forth in Section 2 hereof) for sufficient
"cause," which cause is defined specifically in the event that the Executive is
guilty of (i) a willful and reckless disregard to perform his duties as set
forth in Section 3 herein, or (ii) willful misfeasance for which the Company is
directly and adversely affected, or (iii) any act of dishonesty by the Executive
bearing directly upon the Company. Termination of the Executive's employment by
the Company for reckless disregard of his duties to the Company, willful
misfeasance or an act of dishonesty with respect to the Company hereunder shall
constitute, and is referred to elsewhere herein, as termination for "Cause."
Such termination of the Executive's

                                       4
<PAGE>

employment hereunder for Cause shall be effective upon delivery of written
notice to the Executive which notice shall be a sworn affidavit from at least
two non-interested parties, setting forth with specificity the exact nature of
the "cause" for which the Executive is being terminated. Upon the termination of
this Agreement for "cause" as set forth in this subparagraph, the Company shall
not be obligated to make any further payments hereunder to the executive.

          (b)  Notwithstanding any provisions in this Agreement to the contrary,
the Company may terminate the employment of the Executive without Cause, but in
such event the Company shall be obligated to pay the Executive any and all
amounts payable to the Executive pursuant to Section 4 above for the greater of
(i) the remainder of the initial term or the extended term, as the case may be,
of the Agreement in effect immediately prior to such termination, or (ii) one
(1) year (the "Remainder Term"), and the Company shall also continue for the
Remainder Term to permit the Executive to receive or participate in all fringe
benefits available to him pursuant to Section 5 above; provided, however, that
during the Remainder Term any amounts payable to the Executive pursuant to this
Section 11(b), and any fringe benefits which he receives or in which he
participates pursuant to this Section 11(b), shall be reduced by any payments or
fringe benefits the Executive shall receive during the Remainder Term from any
other source of employment which is unaffiliated with the Company.

     12.  CHANGE OF CONTROL.

          (a)  A "change of control" shall be deemed to occur when

               (i)  the Executive is not elected as an officer of the Company
(or one of its subsidiaries or affiliates);

               (ii) the Company's shareholders approve (x) a merger or
consolidation in which the Company is not the surviving corporation and/or which
results in any reclassification or reorganization of the then outstanding Common
Stock, (y) a sale of all or substantially all of the Company's assets or capital
stock or (z) a plan of liquidation or dissolution of Company;

               (iii) the Common Stock is first purchased pursuant to a tender or
exchange offer (other than a tender or exchange offer made by the Company)
affecting at least 25% of the Common Stock or any other sale of at least 25% of
the Common Stock to a person or group of persons who are not officers, directors
or 5% shareholders of the Company on the date hereof; or

               (iv) there is any other material change in ownership or
management of the Company after which (x) the Executive is terminated or (y) in
the sole determination of the Executive, there is a significant change in the
Executive's duties, responsibilities, principal location of employment, or
compensation.

          (b)  In the event a change of control occurs at any time during the
term of this Agreement:

               (i)  the Executive may, by written notice to the Company within
sixty (60) days after the date of such change of control, elect to terminate his
employment with the Company within sixty (60) days after such notice (the
"Termination Date"). If the Executive elects to terminate

                                       5
<PAGE>

his employment pursuant to this Section 12, the Company shall pay the Executive,
in addition to the remainder of his annual compensation, a "parachute payment,"
as said term is defined in Section 280G of the Internal Revenue Code of 1986, as
amended, (the "Code") in an amount equal to 2.99 times the Executive's annual
compensation (or such other amount then permitted by the Code), including the
Base Salary, bonus compensation or other remuneration and fringe benefits, if
any. This amount shall be payable by the Company to the Executive in one lump
sum payment within sixty (60) days of the Termination Date. The Executive shall
be responsible for payment of all income or excise taxes which may become due as
a result of the Company's payment to him of any "excess parachute payments," as
such phrase is defined in Section 280G of the code, and

               (ii) any options beneficially owned by the Executive at the time
of such change in control shall immediately vest in full and shall be
exercisable by the Executive at any time prior to the expiration date of the
respective options.

     13.  ARBITRATION OF DISPUTES. All controversies, claims and disputes
arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration conducted by the American Arbitration Association, in
accordance with the Commercial Arbitration Rules of said Association in effect
at the time of the controversy, claim or dispute. Judgment upon the award
rendered by the Arbitrator (or Arbitrators) may be entered in any court having
jurisdiction thereof.

     14.  SUCCESSORS AND ASSIGN. This Agreement shall inure to the benefit of
and be binding upon the Company, its successors and assigns, and upon the
Executive, his heirs, executors, administrators, legatees and legal
representatives.

     15.  NOTICE. Any notice, statement, report, request or demand required or
permitted to be given by this Agreement shall be in writing, and shall be
sufficient if delivered in person or if addressed and sent by certified mail,
return receipt requested, to the parties of the addresses set forth above, or at
such other place that either party may designate by notice in the foregoing
manner to the other.

     16.  WAIVER. The failure of either party to insist upon the strict
performance of any of the terms, conditions and provisions of this Agreement
shall not be construed as a waiver or relinquishment of future compliance
therewith, and said terms, conditions and provisions shall remain in full force
and effect. No waiver of any term or any condition of this Agreement on the part
of either party shall be effective for any purpose whatsoever unless such waiver
is in writing and signed by such party.

     17.  MISCELLANEOUS.

          (a)  Should any part of this Agreement, for any reason whatsoever, be
declared invalid, illegal, or incapable of being enforced in whole or in part,
such decision shall not affect the validity of any remaining portion, which
remaining portion shall remain in full force and effect as if this Agreement had
been executed with the invalid portion thereof eliminated, and it is hereby
declared the intention of the parties hereto that they would have executed the
remaining portion of this Agreement without including therein any portion which
may for any reason be declared invalid.

          (b)  This Agreement shall be construed and enforced in accordance with

without application to the principles or conflicts of laws.

          (c)  This Agreement and all rights hereunder are personal to the
Executive and shall not be assignable, and any purported assignment in violation
thereof shall be null and void. Any person, firm or corporation succeeding to
the business of the Company by merger, consolidation, purchase of assets or
otherwise, shall assume by contract or operation of law the obligations of the
Company hereunder; provided, however, that the Company shall, notwithstanding
such assumption and/or assignment, remain liable and responsible for the
fulfillment of the terms and conditions of the Agreement on the part of the
Company.

          (d)  This Agreement constitutes the entire agreement between the
parties hereto with respect to the terms and conditions of the Executive's
employment by the Company, as distinguished from any other contractual
arrangements between the parties pertaining to or arising out of their
relationship, and this Agreement supersedes and renders null and void any and
all other prior oral or written agreements, understandings, or commitments
pertaining to the Executive's employment by the Company. No variation hereof
shall be deemed valid unless in writing and signed by the parties hereto, and no
discharge of terms hereof shall be deemed valid unless by full performance by
the parties hereto or by a writing signed by the parties hereto. No waiver by
either party of any provision or condition of this Agreement by him or it to be
performed shall be deemed a waiver of similar or dissimilar provisions and
conditions at the same time or any prior or subsequent time.

          (e)  The heading of the paragraphs herein are inserted for convenience
and shall not affect any interpretation of this Agreement.

     IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as
