hereunder to have the Executive elected to the Board of Directors during the
Employment Period.

          (b) During the Employment Period, and excluding any periods of

performance of the Executive's duties and responsibilities hereunder.

          (c) The Executive's services shall be performed at Devnet's Westport

subject to applicable taxes and withholding.  During the Employment Period, the
Annual Base Salary shall be reviewed for possible merit increases at least
annually.

          (b) Annual Bonus.  For each calendar year or portion of a calendar
              ------------

management incentive program then applicable to the Executive.

          (c) Benefits.  During the Employment Period, the Executive and/or the

documentation of such expenses.

          (f) Options.  The Executive shall be entitled to receive options on
              -------
300,000 shares (the "Options") of the Company's common stock, $.001 par value

Plan (the "Option Plan"), as of the date the  Executive actually commences
employment at the Company (the "Commencement Date") subject to the execution by
the Company and the Executive of a stock option agreement in form satisfactory
to the Company.  The Options issued under this Section 3(f) shall vest equally
over two years from the date hereof; with 50% of the Options vesting one year
from the Commencement Date (provided that the Executive remains employed as of

          (g) If the Executive's employment is terminated pursuant to a
termination for Cause or if the Executive resigns without Good Reason, all of
the then unvested Options shall immediately be canceled and any vested and
unexercised options shall expire immediately upon the Executive's termination or
resignation.  If the Executive is terminated by the Company without Cause, or
resigns for Good Reason (as defined below), the Options shall be dealt with as
provided for in Section 5 below.  In any case, and notwithstanding any provision
of this Agreement to the contrary, (i) the terms and conditions of any Incentive

              --------------
employment during the Employment Period for Cause or without Cause.  For
purposes of this Agreement, the term "Cause" shall be defined as: (A) disloyalty

Executive at the expense of the Company and/or Devnet (including, without
limitation, fraud, embezzlement or dishonesty or breach of business ethics); (B)
acts of moral turpitude or illegal or unprofessional conduct which may adversely
affect the reputation of the Company and/or Devnet and/or their relationship

conduct in connection with the business or affairs of the Company and/or Devnet;
(D) the failure of the Executive to perform his duties and obligations pursuant
to this Agreement; (E) conviction of a felony or crime involving moral turpitude
(or entering into a plea of nolo contendere with respect to such crime); (F)

4(b), the Company shall give written notice to the Executive at least fifteen
days prior to such termination of the Company's intent to terminate, which
notice shall set out in detail the ways in which Executive has failed to

                                       3
<PAGE>

perform, and Executive shall have failed to cure such failure prior to the
expiration of such fifteen day period.

               (c) By the Executive for Good Reason.  (i) For purposes of this
                   --------------------------------
Agreement, "Good Reason" means:


               A.  any change in the Executive's title to one of lesser status;

               B.  any failure by the Company to comply with any provision of
Section 3 of this Agreement, other than failures that are not taken in bad faith
and are remedied by the Company within 20 business days after receipt of written
notice thereof from the Executive; or

               C.   any relocation of Devnet's headquarters outside of
Connecticut, without Executive's consent.

               (ii) A termination of employment by the Executive for Good Reason
shall be effectuated by giving the Company written notice ("Notice of
Termination for Good Reason") of the termination, setting forth the conduct of
the Company that constitutes Good Reason. A termination of employment by the
Executive for Good Reason shall be effective on the next business day following
the date when the Notice of Termination for Good Reason is given.

          (d) Date of Termination.  The "Date of Termination" means the date of
              -------------------
the Executive's death, Disability, or the date on which the termination of the

notice of a termination of employment without Good Reason, as the case may be.

     5.  Obligations of the Company upon Termination.  (a) Other Than for Cause,
         -------------------------------------------       ---------------------
Death or Disability; Good Reason. If, during the Employment Period, the Company
--------------------------------

the Options, in each case as set forth subparagraph (i) below.  The payments and
other provisions provided pursuant to this Section 5(a) are intended as
liquidated damages for the termination of the Executive's employment by the
Company other than for Cause or Disability or for the actions of the Company
leading to a termination of the Executive's employment by the Executive for Good
Reason and shall be the sole and exclusive remedy therefor; provided further
                                                            -------- -------

due and owing by the Company; and (3) any accrued but unpaid vacation time (but
without giving effect to any carry-over of unused time from prior years), in

period equal to the lesser of (1) six months from the Date of Termination or (2)
the remaining portion of the Employment Period.

          C.  The benefits to be continued for up to six months from the Date of
Termination are group medical benefits to the Executive and/or the Executive's
family comparable to those provided to the Executive under this Agreement;
provided, however, that during any period when the Executive is eligible to

receive such benefits under another employer-provided plan, the benefits
provided hereunder shall terminate.

          D.  All the then unvested Options shall vest and Executive shall
have 12 months from the Date of Termination (unless any applicable Option Plan
provision shall require a shorter period) to exercise such options; provided
that during such 12 month period the Executive otherwise complies with the

provisions of the Agreement applicable to his post-termination conduct.

          (b) Death or Disability.  If the Executive's employment is terminated
              -------------------
by reason of the Executive's death or Disability during the Employment Period,
the Company shall pay the Accrued Obligations to the Executive or the
Executive's estate or legal representative, as applicable, in a lump-sum payment
(subject to applicable taxes and withholding) within 30 days after the Date of
Termination, and the Company shall have no further obligations under this
Agreement.  In the event of the Executive's death, all of the unvested Options
relating solely to the First Option Tranche shall vest and shall be governed by
the terms of the Option Plan and relevant stock option agreement.  In the event
of the Executive's disability, the Options shall be governed by the terms of the
Option Plan and relevant stock option agreements.

          (c) Cause; Other than for Good Reason.  If the Executive's employment
              ---------------------------------
is terminated by the Company for Cause during the Employment Period, or if the
Executive terminates his employment during the Employment Period other than for
Good Reason, the Company shall pay the Executive, in a lump-sum payment (subject
to applicable taxes and withholding) within 30 days of the Date of Termination,
any earned and unpaid Annual Base Salary through the Date of Termination, and
any Options held by the Executive shall be

                                       5
<PAGE>

immediately canceled as provided for in Section 3(g) hereof, and the Company
shall have no further obligations under this Agreement.

     6.  Confidential Information; Noncompetition; Work Product.  The Executive
         ------------------------------------------------------
acknowledges that as a key shareholder, and senior executive of Devnet he is
familiar with a range of confidential proprietary information regarding Devnet
and that he is receiving consideration in connection with the sale of Devnet and
the acquisition by the Company of the goodwill of the business.  The Executive
further acknowledges and agrees that his employment by the Company will,
throughout the Employment Period bring him into close contact with the
confidential affairs of the Company and Devnet, including information about
customers, costs, profits, real estate, markets, sales, products, key personnel,
pricing policies, operational methods, technical processes and other business
affairs and methods and other information not readily available to the public,
and plans for future development.  The Executive further acknowledges that the
services to be performed under this Agreement are of a special, unique, unusual,
extraordinary and intellectual character.  The Executive further acknowledges
that the business of the Company and its subsidiaries is international in scope,
that its products are marketed throughout the world, that the Company competes
in nearly all of its business activities with other entities that are or could
be located in nearly any part of the world and that the nature of the
Executive's services, position and expertise are such that he is capable of
competing with the Company from nearly any location in the world.  In
recognition of the foregoing, the Executive covenants and agrees:

          (a) The Executive, at all times during the Employment Period and
thereafter, shall hold in a fiduciary capacity for the benefit of the Company
all secret, trade, proprietary or confidential information, knowledge or data
relating to the Company or any of its affiliated companies (including Devnet)
and shareholders, and their respective businesses, that the Executive obtains
during the Executive's employment by the Company or any of its affiliated
companies and that is not public knowledge (other than as a result of the
Executive's violation of this Section 6(a)) ("Confidential Information").  The
Executive shall not communicate, divulge or disseminate Confidential Information
at any time during or after the Executive's employment with the Company, except
with the prior written consent of the Company or as otherwise required by law or
legal process.  The Executive shall deliver promptly to the Company on
termination of the Executive's employment by the Company, or at any other time
the Company may so request, at the Company's expense, all memoranda, notes,
records, reports and other documents (and all copies thereof) relating to the
Company's business, which the Executive obtained while employed by, or otherwise
serving or acting on behalf of, the Company and which the Executive may then
posses or have under the Executive's control. The Executive shall execute and
deliver any confidentiality policy or agreement used by the Company for its
senior executives and agrees that in the event of any conflicts, the provisions
of either of this Agreement or any other agreement (as the case may be) which
the Company, in its sole discretion, determines more fully protects the Company
shall govern.

          (b) In consideration of (a) the Company agreeing to enter into this
Agreement, and (b) consideration paid by the Company to Executive in connection
the

                                       6
<PAGE>

Company's acquisition of Devnet, the Executive acknowledges and agrees that
during the "Noncompetition Period," the Executive shall not, without the prior
written consent of the Board, engage in or become associated with a "Competitive
Activity."  For purposes of this Section 6: (i) the "Noncompetition Period"
means the period commencing on the Commencement Date and ending on the twelve
(12) month anniversary of the date upon which Executive's employment with the
Company is terminated for any reason; (ii) a "Competitive Activity" means (a)
the business of Devnet as conducted as of the date of this Agreement and during
the Employment Period, and (b) any business or other endeavor that engages in
any geographic location primarily in the construction, installation, servicing
or operation of in-building communications and/or transmission networks or, to
the knowledge of the Executive, has definitive plans to engage in such conduct;
and (iii) the Executive shall be considered to have become "associated with a
Competitive Activity" if the Executive becomes directly or indirectly involved
as an owner, investor, employee, officer, director, consultant, independent
contractor, agent, partner, advisor, or in any other capacity calling for the
rendition of the Executive's personal services, with any individual,
partnership, corporation or other organization that is engaged directly or
indirectly in a Competitive Activity (other than in connection with an equity
investment in 5% or less of the common stock of a publicly traded company).

          (c) During the Noncompetition Period, the Executive shall not, on his
or her own behalf or on behalf of any other person, firm or entity (x) directly
or indirectly solicit, induce or attempt to solicit or induce any employee of
the Company to terminate his or her employment with the Company, or to provide
any assistance whatsoever to any person, firm or entity engaged in a Competitive
Activity, (y) employ, or cause any business or entity with which Executive is
affiliated to employ, any person who was a full-time executive employee of the
Company at the Executive's Date of Termination or six months prior to such date
or (z) directly or indirectly induce any business, entity or person with which
the Company or any of its subsidiaries or affiliates has a business relationship
to terminate or alter such business relationship.

          (d) In addition to such other rights and remedies as the Company may
have at equity or in law with respect to any breach of this Agreement, if the
Executive commits a material breach of any of the provisions of Section 6, the
Company shall have the right and remedy to have such provisions specifically
enforced by any court having equity jurisdiction (without any obligation to post
a bond or other security); it being acknowledged and agreed that any such breach
or threatened breach will cause irreparable injury to the Company and that money
damages alone will not provide an adequate remedy to the Company.

          (e) The Executive acknowledges that during the Employment Period, the
Executive may conceive of, discover, invent or create inventions, improvements,
new contributions, literary property, computer programs and software material,
ideas and discoveries, whether patentable or copyrightable or not (all of the
foregoing being collectively referred to herein as "Work Product"), and that
various business opportunities shall be presented to the Executive by reason of
the Executive's employment by the Company.  The Executive acknowledges that all
of the foregoing shall be owned by and belong exclusively to

                                       7
<PAGE>

the Company and that the Executive shall have no personal interest therein,
provided that they are either related in any manner to the business (commercial
-------- ----
or experimental) of the Company, or are, in the case of Work Product, conceived
or made on the Company's time or with the use of the Company's facilities or
materials, or, in the case of business opportunities, are presented to the
Executive for the possible interest or participation of the Company. The
Executive shall (i) promptly disclose any such Work Product and business
opportunities to the Company; (ii) assign to the Company, upon request and
without additional compensation, the entire rights to such Work Product and
business opportunities; (iii) sign all papers necessary to carry out the
foregoing; and (iv) give testimony in support of the Executive's inventorship or
creation in any appropriate case. The Executive agrees that the Executive will
not assert any rights to any Work Product or business opportunity as having been
made or acquired by the Executive prior to the date of this Agreement except for
Work Product or business opportunities, if any, disclosed to and acknowledge by
the Company in writing prior to the date hereof.

          (f) The Executive acknowledges and agrees that the provisions of this
Section 6 are necessary to protect the business operations and affairs of the
Company.  The Executive understands that the restrictions set forth in this
Agreement may limit his ability to earn a livelihood in a business similar that
of the Company, but he nevertheless believes that he has received and will
receive sufficient consideration and other benefits as an employee of the
Company to justify clearly such restrictions which, in any event (given his
education, skills and ability), the Executive does not believe would prevent him
from earning a livelihood.

     7.  Successors.  (a) This Agreement is personal to the Executive and,
         ----------
without the prior written consent of the Company, shall not be assignable by the
Executive otherwise than by will or the laws of descent and distribution. This
Agreement shall inure to the benefit of and be enforceable by the Executive's
legal representatives.

          (b) This Agreement shall inure to the benefit of and be binding upon
the Company and its successors and assigns, and may be assigned by Company in
connection with any sale, transfer or other disposition of all or substantially
all of its business and assets.

     8.  Indemnification.  The Executive shall be entitled throughout the
         ---------------
Employment Period in the capacity as an officer or director of the Company or
any of its subsidiaries, or as a member of any other governing body or any
partnership or joint venture in which the Company has an equity interest (and
after the term of employment, to the extent relating to any continued service as
such officer, director or member) to the benefit of the indemnification
provisions contained on the date hereof in the Certificate of Incorporation and
By-Laws of the Company (not including any amendments or additions after the date
of execution hereof that limit or narrow, but including any that add to or
broaden, the protection afforded to the Executive by those provisions), to the
extent not prohibited by applicable law at the time of the assertion of any
liability against the Executive.

     9.  Post-Termination Assistance.  For so long as the Executive is receiving
         ---------------------------
any payments pursuant to this Agreement, the Executive shall cooperate, at the
reasonable request of the Company (i) in the transition of any matter for which
the Executive had authority or

                                       8
<PAGE>

responsibility during the Employment Period, or (ii) with respect to any other
matter involving the Company for which the Executive may be of assistance.

     10.  Miscellaneous.  (a) This Agreement shall be governed by, and construed
          -------------
in accordance with, the laws of the State of New York, applicable to agreements
made and to be performed entirely within such state. The captions of this

regulations.

          (f) The failure of the Executive or the Company to insist upon strict
