            WHEREAS the Company desires to induce the Employee to enter into
employment with the Company for the period provided in this Agreement, and the
Employee is willing to accept such employment with the Company on a full-time
basis, all in accordance with the terms and conditions set forth below;

            NOW, THEREFORE, for and in consideration of the premises hereof and
the mutual covenants contained herein, the parties hereto hereby covenant and
agree as follows:

      the period set forth in Section 2 hereof, all upon the terms and
      conditions hereinafter set forth.

            (b) The Employee affirms and represents that as of the commencement
      of his employment by the Company, he was under no obligation to any former
      employer or other party which is in any way inconsistent with, or which

      hereunder with the Company, the employment of the Employee by the Company,
      or the Employee's undertakings under this Agreement.

            2. Term of Employment. Unless earlier terminated as provided in this
Agreement, the term of the Employee's employment under this Agreement shall be
for a period beginning on the Commencement Date and ending on May 31, 2004. The
period from the Commencement Date until May 31, 2004, or, in the event that the
Employee's employment hereunder is earlier terminated as provided herein, such

Employee shall report to the Chief Executive Officer of the Company. The
Employee shall perform his duties principally at offices

      together with any increases thereto as may be determined from time to time
      by the Board of Directors in its sole discretion, being hereinafter
      referred to as "Salary"). Any Salary payable hereunder shall be paid in
      regular intervals in accordance with the Company's payroll practices from

      the Company in respect of each fiscal year (or portion thereof) occurring
      during the Employment Term in an amount targeted at 40% of his Salary (pro

      fiscal year. In accordance with the foregoing conditions, the Employee
      shall also be eligible to receive additional bonus compensation from the

            (d) Fair Market Value. "Fair Market Value" means as of any date, the

                  (i) If the Common Stock is listed on any established stock

      Inc. Automated Quotation ("NASDAQ") System, the Fair Market Value of a

                                       3
   4
      price for such stock (or the closing bid, if no sales were reported) as
      quoted on such system or exchange (or the exchange with the greatest
      volume of trading in Common Stock) on the last market trading day prior to
      the day of grant of the particular Subsequent Options and as reported in
      the Wall Street Journal or such other source as the Compensation Committee
      deems reliable;

                  (ii) If the Common Stock is quoted on the NASDAQ System (but

      recognized securities dealer but selling prices are not reported, the Fair
      Market Value of a share of Common Stock shall be the average between the

                  (iii) In the absence of an established market for the Common
      Stock, the Fair Market Value shall be determined in good faith by the
      Compensation Committee.

            6. Confidential Information. The Employee hereby covenants, agrees
and acknowledges as follows:

            (a) The Employee has and will have access to and will participate in
      the development of or be acquainted with confidential or proprietary
      information and trade secrets related to the business of the Company and
      any present or future subsidiaries or affiliates of the Company
      (collectively with the Company, the "Companies"), including but not
      limited to (i) customer lists; related records and compilations of
      information; the identity, lists or descriptions of any new customers,
      referral sources or organizations; financial statements; cost reports or
      other financial information; contract proposals or bidding information;
      business plans; training and operations methods and manuals; personnel
      records; software programs; reports and correspondence; and management
      systems, policies or procedures, including related forms and manuals; (ii)
      information pertaining to future developments such as future marketing or
      acquisition plans or ideas, and potential new business locations and (iii)
      all other tangible and intangible property, which are used in the business
      and operations of the Companies but not made public. The information and
      trade secrets relating to the business of the Companies described
      hereinabove in this paragraph (a) are hereinafter referred to collectively
      as the "Confidential Information", provided that the term Confidential
      Information shall not include any information (A) that is or becomes
      generally publicly available (other than as a result of violation of this
      Agreement by the Employee), (B) that the Employee receives on a
      nonconfidential basis from a source (other than the Companies or their
      representatives) that is not known by him to be bound by an obligation of
      secrecy or confidentiality to any of the Companies or (C) that was in the
      possession of the Employee prior to disclosure by the Companies.

            (b) The Employee shall not disclose, use or make known for his or
      another's benefit any Confidential Information or use such Confidential
      Information in any way


                                       4
   5
      except as is in the best interests of the Companies in the performance of
      the Employee's duties under this Agreement. The Employee may disclose
      Confidential Information when required by a third party and applicable law
      or judicial process, but only after providing immediate notice to the
      Company of any third party's request for such information, which notice
      shall include the Employee's intent to disclose any Confidential
      Information with respect to such request.

            (c) The Employee acknowledges and agrees that a remedy at law for
      any breach or threatened breach of the provisions of this Section 6 would
      be inadequate and, therefore, agrees that the Companies shall be entitled
      to seek injunctive relief in addition to any other available rights and
      remedies in case of any such breach or threatened breach by the Employee;
      provided, however, that nothing contained herein shall be construed as
      prohibiting the Companies from pursuing any other rights and remedies
      available for any such breach or threatened breach.

            (d) The Employee agrees that upon termination of his employment with
      the Company for any reason, the Employee shall forthwith return to the
      Company all Confidential Information in whatever form maintained
      (including, without limitation, computer discs and other electronic
      media).

            (e) The obligations of the Employee under this Section 6 shall,
      except as otherwise provided herein, survive the termination of the
      Employment Term and the expiration or termination of this Agreement.

            (f) Without limiting the generality of Section 12 hereof, the
      Employee hereby expressly agrees that the foregoing provisions of this
      Section 6 shall be binding upon the Employee's heirs, successors and legal
      representatives.

            7. Termination of Employment.

            (a) The Employee's employment hereunder shall be terminated upon the
      occurrence of any of the following:

                  (i) death of the Employee;

                  (ii) the Employee's inability to perform his duties on account
      of disability or incapacity for a period of one hundred eighty (180) or
      more days, whether or not consecutive, within any period of twelve (12)
      consecutive months;

                  (iii) the Company giving written notice, at any time, to the
      Employee that the Employee's employment is being terminated for "Cause"
      (as defined in (b) below);


                                       5
   6
                  (iv) the Company giving written notice, at any time, to the
      Employee that the Employee's employment is being terminated or is not
      being renewed, other than pursuant to clause (i), (ii) or (iii) above
      ("Without Cause");

                  (v) the Employee terminates his employment hereunder because
      the Company, solely due to an Executive Management Stockholder Block (as
      defined in (c) below), fails to consummate an initial public offering of
      its Common Stock within one (1) year of the Commencement Date; or

                  (vi) the Employee terminates his employment hereunder for any
      reason whatsoever (whether by reason of retirement, resignation or
      otherwise), other than in accordance with (v) above ("Without Good
      Reason").

            (b) Cause. The following actions, failures and events by or
      affecting the Employee shall constitute "Cause" for termination within the
      meaning of clause (iii) of Section 7 (a) above:

                  (i) an indictment for or conviction of the Employee of, or the
      entering of a plea of nolo contendere by the Employee with respect to,
      having committed a felony;

                  (ii) abuse of controlled substances or alcohol or acts of
      dishonesty or moral turpitude by the Employee that are detrimental to one
      or more of the Companies;

                  (iii) acts or omissions by the Employee that the Employee knew
      were likely to damage the business of one or more of the Companies;

                  (iv) negligence by the Employee in the performance of, or
      disregard by the Employee of, his material obligations under this
      Agreement or otherwise relating to his employment, which negligence or
      disregard continue unremedied for a period of fifteen (15) days after
      written notice thereof to the Employee; or

                  (v) failure by the Employee to obey the reasonable and lawful
      orders and policies of the Board of Directors that are consistent with the
      provisions of this Agreement.

            (c) Executive Management Stockholder Block. For purposes of this
      Agreement, an "Executive Management Stockholder Block" means the decision
      by the Company's Executive Management Stockholders (as that term is
      defined in the Stockholders Agreement, dated as of July 23, 1998, among
      the Company and the stockholders party thereto, as the same may be amended
      or modified from time to time) to not consent to an initial public
      offering by the Company of its Common Stock; provided, however, that an
      Executive Management Stockholder Block shall not be deemed to have
      occurred if a decision or action by the Board of Directors or the holders
      of the Company's Series A Convertible Preferred Stock, $.001 par value,
      prevents the consummation of such an initial public offering.

      or both, monthly payments at the rate per annum of his Salary at the time

      however, that nothing in this Section 9(a) shall preclude the Employee
      from designating a beneficiary to receive any benefit payable hereunder
      upon his death or incapacity. This Agreement may not be assigned by the
      Company except with the Employee's prior written consent, provided,
      however, that the Company may assign this Agreement to an affiliate of the
      Company with the financial resources to fulfill the Company's obligations

            (b) Except as required by law, no right to receive payments under

      an adverse effect on the business, assets or financial condition of any of
      the Companies, or materially interfere with the relationship between any

            (e) Certain Representations of the Employee. In connection with the
      foregoing provisions of this Section 10, the Employee represents that his
      experience, capabilities and circumstances are such that such provisions
      will not prevent him from earning a livelihood. The Employee further
      agrees that the limitations set forth in this Section 10 (including,
      without limitation, time and territorial limitations) are reasonable and
      properly required for the adequate protection of the current and future
      businesses of the Companies. It is understood and agreed that the
      covenants made by the Employee in this Section 10 (and in Section 6
      hereof) shall survive the expiration or termination of this Agreement.

            (f) Injunctive Relief. The Employee acknowledges and agrees that a
      remedy at law for any breach or threatened breach of the provisions of
      Section 10 hereof would



                                       9
   10
      be inadequate and, therefore, agrees that the Company and any of its
      subsidiaries or affiliates shall be entitled to seek injunctive relief in
      addition to any other available rights and remedies in cases of any such
      breach or threatened breach; provided, however, that nothing contained
      herein shall be construed as prohibiting the Company or any of its
      affiliates from pursuing any other rights and remedies available for any
      such breach or threatened breach.

            11. Representations and Warranties. The Employee represents and
warrants that he is not subject to or a party to any agreement, contract,
covenants, order or other restriction which in any way prohibits, restricts or
impairs the Employee's ability to enter into this Agreement and carry out his
duties and obligations hereunder. Each party hereto represents and warrants to
the other that (i) each has the full legal right and power and all authority and
approvals required to enter into, execute and deliver this Agreement and to
perform fully all of his or its obligations hereunder; and (ii) this Agreement
has been duly executed and delivered and constitutes a valid and binding
obligation of each party, enforceable in accordance with its terms.

            12. Binding Effect. Without limiting or diminishing the effect of
Section 9 hereof, this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective heirs, successors, legal
representatives and assigns.

            13. Notices. All notices which are required or may be given pursuant
to the terms of this Agreement shall be in writing and shall be sufficient in
all respects if given in writing and (i) delivered personally, (ii) mailed by
certified or registered mail, return receipt requested and postage prepaid,
(iii) sent via a nationally recognized overnight courier or (iv) sent via
facsimile confirmed in writing to the recipient, if to the Company at the
Company's principal place of business, and if to the Employee, at his home
address most recently filed with the Company, or to such other address or
addresses as either party shall have designated in writing to the other party
hereto, provided, however, that any notice sent by certified or registered mail
shall be deemed delivered on the date of delivery as evidenced by the return
receipt.

            14. Law Governing. This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.

            15. Severability. The Employee agrees that in the event that any
court of competent jurisdiction shall finally hold that any provision of Section
6 or 10 hereof is void or constitutes an unreasonable restriction against the
Employee, the provisions of such Section 6 or 10 shall not be rendered void but
shall apply with respect to such extent as such court may judicially determine
constitutes a reasonable restriction under the circumstances. If any part of
this Agreement other than Section 6 or 10 is held by a court of competent
jurisdiction to be invalid, illegible or incapable of being enforced in whole or
in part by reason of any rule of law or public policy, such part shall be deemed
to be severed from the remainder of this Agreement for the purpose only of the
particular legal proceedings in question and all other covenants and provisions
of this Agreement shall in every other respect continue in full force and effect
and no covenant or provision shall be deemed dependent upon any other covenant
or provision.

   11
            16. Waiver. Failure to insist upon strict compliance with any of the
terms, covenants or conditions hereof shall not be deemed a waiver of such term,
covenant or condition, nor shall any waiver or relinquishment of any right or
power hereunder at any one or more times be deemed a waiver or relinquishment of
such right or power at any other time or times.

            17. Entire Agreement; Modifications. This Agreement constitutes the
entire and final expression of the agreement of the parties with respect to the
subject matter hereof and supersedes all prior agreements, oral and written,
between the parties hereto with respect to the subject matter hereof. This
Agreement may be modified or amended only by an instrument in writing signed by
both parties hereto.

            18. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

            IN WITNESS WHEREOF, the Company and the Employee have duly executed
and delivered this Agreement as of the day and year first above written.
