         NOW, THEREFORE, for and in consideration of the premises hereof and

     conditions hereinafter set forth.

         (b)      The Employee affirms and represents that as of the

     under this Agreement.

   4

     Each grant of these Subsequent Options shall be pursuant to specific terms

         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 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

                                       4

   5

     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.

                  (iii)    the Company giving written notice, at any time, to
     the Employee that the Employee's employment is being terminated for

     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.

   8


         (a)      Competition. During the Employment Term and, in the event the
     Employee's employment is terminated, during the period (the "Applicable
     Continuation Period") following such termination and continuing until (i)
     the last payment is made to the Employee pursuant to Section 8(a) hereof
     or (ii) in the case of a termination of the Employee's employment pursuant
     to Section 7(a)(iii) or (v) hereof, the first anniversary of the date of
     such termination, the Employee will not directly or indirectly (as a
     director, officer, executive employee, manager, consultant, independent
     contractor, advisor or otherwise) engage in competition with, or own any
     interest in, perform any services for, participate in or be connected with
     any business or organization which engages in competition with any of the
     Companies within the meaning of Section 10(d), provided, however, that the
     provisions of this Section 10(a) shall not be deemed to prohibit the
     Employee's ownership of not more than two percent (2%) of the total shares
     of all classes of stock outstanding of any publicly held company, or
     ownership, whether through direct or indirect stock holdings or otherwise,
     of not more than one percent (1%) of any other business.

         (b)      Non-Solicitation. During the Employment Term and during the
     Applicable Continuation Period, the Employee will not directly or
     indirectly induce or attempt to induce any employee of any of the
     Companies to leave the employ of the Company or such subsidiary or
     affiliate, or in any way interfere with the relationship between any of
     the Companies and any employee thereof.

         (c)      Non-Interference. During the Employment Term and during the
     Applicable Continuation Period, the Employee will not directly or
     indirectly hire, engage, send any work to, place orders with, or in any
     manner be associated with any supplier, contractor, subcontractor or other
     business relation of any of the Companies if such action by him would have
     an adverse effect on the business, assets or financial condition of any of
     the Companies, or materially interfere with the relationship between any
     such person or entity and any of the Companies.

         (d)      Certain Definitions.

                  (i)      For purposes of this Section 10, a person or entity
     (including, without limitation, the Employee) shall be deemed to be a
     competitor of one or more of the Companies, or a person or entity
     (including, without limitation, the Employee) shall be deemed to be
     engaging in competition with one or more of the Companies, if such person
     or entity conducts, or, to the knowledge of the Employee, plans to
     conduct, the Specified Business (as hereinafter defined) as a significant
     portion of its business in any of the markets served by the Companies or,
     in the case of a person or entity pursuing a business strategy of
     providing telecommunications infrastructure services, anywhere in the
     continental United States.

                                       8

   9


                  (ii)     For purposes of this Agreement, "Specified Business"
     means (A) providing outsourced telecommunications infrastructure services
     to local or long distance telecommunications providers or engaging in any
     business conducted by the Company at the time of termination of the
     Employee's employment with the Company or (B) conducting, operating,
     carrying out or engaging in the business of managing any entity described
     in clause (A).

         (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 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.

                                       9

   10


         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.

         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
