Community Networks,  Inc., a Delaware corporation ("Community  Networks"),  Tech
Labs Community  Networks of the  Southeast,  Inc., a Delaware  corporation  (the
"Company") and m3communications,  Inc., a Florida corporation ("m3").  Community
Networks and m3 are individually referred to as a "Stockholder" and collectively
as the "Stockholders."

                                   WITNESSETH:

     The Company is a corporation  organized  under and by virtue of the laws of
the State of Delaware and has an authorized  capitalization of one thousand five
hundred  (1,500) shares of common stock, no par value (the "Common  Stock"),  of
which no shares are issued and outstanding.

     Upon the closing of the transactions by and between Tech Laboratories, Inc.
("Tech Labs"),  Community Networks, the Company, m3, and the shareholders of m3,
pursuant to which m3 is selling to the Company  certain  assets and contracts to
provide  telecommunications  services to property  developments in consideration
for Tech Labs' and  Community  Networks'  transfer of shares of common  stock in
Tech Labs and the  Company to m3, the  Stockholders  shall own all of the issued
and  outstanding  shares of Common  Stock of the  Company,  the holdings of each
Stockholder being as follows:

                         Community Networks 1,200 shares
                         m3                   300 shares

     The  shares  of  stock  of the  Company  described  above  as  owned by the
Stockholders   and  any  shares  of  such  stock  hereafter   acquired  by  such
Stockholders and permitted transferees are referred to herein as the "Stock."

     The parties  hereto deem it expedient for the best interests and welfare of
the Company and its  Stockholders  to provide for the future  disposition of the
Stock by imposing  certain  restrictions  and obligations on themselves and such
Stock.

SECTION 2. RESTRICTION OF SALE OR TRANSFER; PUT OPTION.

     2.1. Restriction. M3, or its successors or assigns, shall not sell, assign,
hypothecate,  transfer,  pledge, encumber, give away or otherwise dispose of any
Stock except in  compliance  with the terms and  conditions  of this  Agreement;
provided,  however, m3 may transfer, as permitted by law, shares of the Stock to
its  shareholders,  which  transfer shall not be prohibited by the terms of this
Agreement.

     2.2.  Offer.  Should  m3 or its  successors  or  assigns  desire to sell or
otherwise  dispose of all or any portion of its Stock,  m3 or its  successors or
assigns shall make an offer to Community  Networks  specifying the terms of sale

                                       -2-





right and option to purchase such shares of Stock before the shares of Stock may
be offered to any other  party,  which may only be offered to any third party on
terms no more favorable than those offered to Community Networks.

     2.3.  General.  Every offer  pursuant to this Section 2 shall be in writing
and shall state that m3, or its  successors or assigns,  offers to sell all or a
portion  (specifying such number), as the case may be, of its Stock to Community
Networks.  Community  Networks  shall have the option,  within  thirty (30) days
after receipt of such offer, to purchase all or a portion of the shares of Stock
offered for sale by m3 or its successors or assigns.

     2.4.  Remaining  Shares.  Any  shares  of  Stock  offered  for sale but not
acquired by Community  Networks as provided in this Section 2 may be sold on the
open market free of the restrictions contained in this Agreement, providing that
(i) any such sale shall be on terms not more favorable to the purchaser(s)  than
those provided for in the offer, (ii) such sale shall be made within ninety (90)
days from the last date upon which  Community  Networks was entitled to purchase
said shares under the  provisions  of this  Agreement and (iii) such sale in the
manner proposed to be made by m3 would not, in the written opinion of counsel to
the  Company,  be in violation  of the  Securities  Act of 1933 or the Rules and
Regulations  of the  Securities and Exchange  Commission  thereunder,  or of any
applicable  state  securities  or "Blue  Sky" laws or any rules and  regulations
promulgated  thereunder.  If no such sale is made by m3 within  said ninety (90)
days period,  then all of the  provisions of this  Agreement  shall apply to any
disposition of the shares as if no offer to sell had been made.

SECTION 3. PREEMPTIVE RIGHTS

     3.1. Rights of Inclusion.

     3.1.1.  General.  Except as  provided in Section  3.1.6.,  if, at any time,
Community  Networks or its  successors or assigns  proposes to transfer Stock in
the Company to a third party (a "Proposed Purchaser"),  Community Networks shall
afford m3 or its  successors or assigns the  opportunity  to participate in such
transfer to such third party in accordance with this Section 3.1.

     3.1.2. Right to Participate.  M3 or its successors or assigns, with respect
to the proposed  transfers set forth in Section 3.1.1.,  shall have the right to
transfer its Stock in the Company in proportion to the amount of Stock  proposed
to be  transferred  by  Community  Networks or its  successors  or assigns  (the
"Transfer Allotment"), at the same price and upon identical terms and conditions
as such proposed  transfer.  At the time any transfer to a Proposed Purchaser is
proposed,  Community  Networks or its successors or assigns shall give notice to
m3 of its right to sell Shares hereunder (the "Transfer  Notice"),  which notice
shall  identify the Proposed  Purchaser and state the number of shares of Common
Stock proposed to be transferred, the proposed offering price, the proposed date
of any such  transfer (the  "Transfer  Date") and any other  material  terms and
conditions of the proposed  transfer.  The Transfer  Notice shall also contain a
complete and correct copy of any offer to Community  Networks or its  successors
or assigns by the Proposed Purchaser to purchase such Common Stock.


                                       -3-





     3.1.3.  Notice. If m3 or its successors or assigns wishes to participate in
the  transfer  it shall  provide  written  notice  (the  "Tag-Along  Notice") to
Community  Networks  or its  successors  or  assigns no less than seven (7) days
prior to the Transfer Date;  provided that Community  Networks or its successors
or assigns  shall use its best efforts to deliver the  Transfer  Notice at least
thirty  (30) days prior to the  Transfer  Date and in no event  shall  Community
Networks or its  successors or assigns  provide such Transfer  Notice later than
fifteen (15) business  days prior to the Transfer  Date.  The  Tag-Along  Notice
shall set forth the  number  of  shares of Stock  that m3 or its  successors  or
assigns  elects to include in the transfer,  which shall not exceed the Transfer
Allotment.  The Tag-Along Notices given by m3 or its successors or assigns shall
constitute a binding  agreement to sell such shares on the terms and  conditions
applicable to the transfer.

     3.1.4.  Non  Participation.  If a  Tag-Along  Notice  is  not  received  by
Community Networks prior to the seven (7) day period specified above,  Community
Networks or its  successors or assigns shall have the right to sell or otherwise
transfer the Stock  specified in the Transfer  Notice to the Proposed  Purchaser
without any participation by m3 or its successors or assigns,  but only on terms
and  conditions  with  respect  to the  consideration  offered  by the  Proposed
Purchaser  and other  material  terms a reasonable  investor  would  consider in
making its  decision  to invest,  which are no more  favorable  in any  material
respect to Community Networks or its successors or assigns than as stated in the
Transfer  Notice,  and only if such transfer  occurs on a date within sixty (60)
days of the Transfer Date.

     3.1.5.  Representations.  M3 or its  successors  and assigns  shall only be
obligated  to make  representations  as to (A) good  title and the  absence of a
Security Interest against m3's stock, (B) the validity and binding effect of any
agreements entered into by m3 in connection with such transfer.

     3.1.6.  Exceptions.  The  provisions of this Section 3 shall not apply to a
transfer by  Community  Networks to an affiliate or  subsidiary  corporation  of
Community Networks.

     3.2. Right of First Offer.

     3.2.1.  General.  Subject  to the terms and  conditions  specified  in this
Section 3.2.,  Community  Networks and the Company hereby grant to m3 a right of
first offer with respect to any new  issuances or future sales by the Company of
the  Company's  Common  Stock.  Each  time the  Company  proposes  to offer  (A)
additional  Common  Stock in the  Company,  (B)  rights,  options or warrants to
purchase Common Stock in the Company,  or (C) securities  convertible  into such
Common Stock in the Company (the "New Offering"),  the Company shall first offer
to m3 the  option  of  purchasing,  at a  maximum,  such  percentage  of the New
Offering which equals m3's current  proportionate  share of the Company's  total
Common Stock (the  "Purchase  Allotment")  at the time of the  proposed  sale in
accordance with the following provisions.

     3.2.2.  Notice.  The Company shall provide a written  notice (the "Offering
Notice") of the New Offering to m3 stating (A) the Company's bona fide intention
to offer such Common  Stock,  (B) the amount of the Common Stock being  offered,
and (C) the price and terms upon which it proposes to offer such Common Stock in
the Company.


                                       -4-





     3.2.3. Election to Purchase.  Within twenty (20) days following the date of
the Offering  Notice (the "Election  Period"),  m3 may elect to purchase  Common
Stock in the New Offering, but in no event shall such amount be greater than the
Purchase Allotment.

     3.2.4.  Transfer  of  Proposed  Purchaser.  At any time after the  Offering
Notice is given,  the  Company  may offer for sale the  Common  Stock of the New
Offering  less the  amount of (A) the  amount m3 elects to  purchase  or (B) the
Purchase Allotment,  and, if the Common Stock referred to in the Offering Notice
is not elected to be purchased as provided in Section  3.2.3.,  the Company may,
during the ninety  (90) day period  following  the  expiration  of the  Election
Period, offer for sale the remaining unsubscribed portion of the New Offering to
any Person at a price not less than,  and upon  terms no more  favorable  to the
offeree than those  specified in the  Offering  Notice.  If the Company does not
consummate the sale of the New Offering  within such period,  the right provided
hereunder  shall be deemed to be revived  and such  shares  shall not be offered
unless first reoffered to m3 in accordance with this section.

     3.2.5.  Exceptions.  The right of first offer in this Section 3.2 shall not
be applicable  (A) to the issuance of securities in connection  with a strategic
acquisition  by the  Company  involving  the  assumption  of  control of another
company,  whether by merger,  consolidation,  sale of  substantially  all of its
assets,  sale or  exchange  of  stock  or  otherwise,  (B) to any  affiliate  or
shareholder of m3 or any transferee receiving shares of Stock from m3 so long as
such person executes a copy of this Agreement, or (C) the issuance of any equity
security or the grant of any option warrant or other right to acquire any equity
security to any  employee,  officer,  or director of the Company so long as such
issuance or grant is at market value on the date of such issuance or grant.

SECTION 4. OBLIGATIONS UNDER PUBLIC OFFERING

     In the event the Company files, under the Securities  Exchange Act of 1933,
a public offering  covering the registration of shares of Common Stock valued in
excess of two million dollars ($2,000,000),  the Stockholders covenant and agree
as follows:

     4.1. Lock-Up Period. The Stockholders shall not, to the extent requested by
the underwriter of the Company,  sell or otherwise transfer or dispose of any of
its Stock,  to the extent any of such shares are  included  in the  registration
statement,  during  the one  hundred  eighty  (180)  day  period  following  the
effective  date  of a  registration  statement;  provided,  however,  that  such
agreement  shall be applicable (i) only to the first  registration  statement of
the  Company  that  covers  shares to be sold on its behalf to the public in the
underwritten  offering,  and (ii) only a  Stockholder  holding in excess of more
than five percent (5%) of the outstanding shares of Common Stock.

SECTION 5. ELECTION OF DIRECTORS

party hereto.

     7.2. Consent to Assignment.  Notwithstanding  Section 8.1 hereof,  prior to
