Warrant No. A-1                           Date of Issuance:  December __, 1996

                           ABLE TELCOM HOLDING CORP.

                         Common Stock Purchase Warrant

       Able Telcom  Holding Corp. (the "Company"),  for value  received,  hereby
certifies  that   ________________________,   or  its  registered  assigns  (the
"Registered  Holder"),  is entitled,  subject to the terms set forth  below,  to
purchase  from the  Company,  at any time and from  time to time on or after the
first  anniversary  of the date hereof  (except as provided in Section 8 hereof)
and on or before  the  Expiration  Date (as  defined  in  Section 6 below)  (the
"Exercise Period") ______ shares of Common Stock of the Company, par value $.001
per share (the "Common  Stock"),  at a purchase  price per share equal to $9.82.
The shares purchasable upon exercise of this Warrant, and the purchase price per
share shall be adjusted  from time to time  pursuant to the  provisions  of this
Warrant and are hereinafter referred to as the "Warrant Stock" and the "Purchase
Price," respectively.

      This  Warrant  is issued  pursuant  to,  and is  subject  to the terms and
conditions of the Series A Preferred Stock Purchase Agreement dated December 20,
1996, by and among the Company and certain Investors (the "Purchase Agreement").

      1. Number of Shares.  Subject to the terms and conditions  hereinafter set
forth,  the Registered  Holder is entitled,  upon surrender of this Warrant,  to
purchase  from the Company up to  ________  shares of Common  Stock,  subject to
adjustment as set forth herein.

      2.    Exercise.

      (a) Manner of Exercise.  This  Warrant may be exercised by the  Registered
Holder, in whole or in part, by surrendering this Warrant at any time during the
Exercise  Period,  with the  purchase  form  appended  hereto as  Exhibit A duly
executed  by  such  Registered  Holder  or  by  such  Registered  Holder's  duly
authorized  attorney,  at the principal office of the Company,  or at such other
office or agency as the Company may designate in writing, accompanied by payment
in full of the  Purchase  Price  payable  in  respect of the number of shares of
Warrant Stock purchased upon such exercise,  and applicable documentary stamp or
other taxes. The total purchase price may be paid by cash, check, wire transfer,
or if requested by  Registered  Holder in the purchase  form,  in the manner set
forth in the following paragraph.  Notwithstanding the foregoing, the Registered
Holder may only  exercise this Warrant for such number of shares of Common Stock
that would result in such Registered Holder being the beneficial owner of up to,
but no more than 4.99% of the Company's then outstanding Common Stock; provided,
however, that the limitation described in this subsection 2(a) shall not prevent
a Registered  Holder from  exercising  this Warrant at any other time thereafter
that does not result in the Registered Holder exceeding such limit.


                                      1





      In  addition  to the method of payment  set forth above and in lieu of any
cash payment  required,  the Registered Holder shall have the right, at any time
that there does not exist an effective  registration statement filed pursuant to
the Securities Act covering the Warrant Stock,  to exercise this Warrant in full
or in part by  surrendering  this  Warrant  in the  manner  specified  above  in
exchange  for the number of shares of Warrant  Stock equal to the product of (x)
the number of shares as to which this Warrant is being  exercised  multiplied by
(y) a fraction,  the  numerator of which is the Market Price (as defined  below)
less the Purchase Price,  and the denominator of which is the Market Price.  For
purpose of this  paragraph,  the term  "Market  Price"  shall  mean the  average
closing  bid  price  quoted on a share of Common  Stock on the  Nasdaq  National
Market  for the  three (3)  trading  days  immediately  prior to the date of the
delivery to the Company of a purchase form (or if the Company's  Common Stock is
not  traded or  listed  on the  Nasdaq  National  Market or any other  principal
securities market, the average of the closing bid prices in the over-the-counter
market on such days as reported by Nasdaq or any comparable system, or if not so
reported, as reported by any New York Stock Exchange member firm selected by the
Company for such purpose.

            (b) Effective Time of Exercise.  Each exercise of this Warrant shall
be deemed to have been  effected  immediately  prior to the close of business on
the day on which this  Warrant  shall have been  surrendered  to the  Company as
provided  in Section  2(a) above.  At such time,  the person or persons in whose
name or names any  certificates  for Warrant  Stock shall be issuable  upon such
exercise as  provided  in Section  2(c) below shall be deemed to have become the
holder  or  holders  of  record  of  the  Warrant  Stock   represented  by  such
certificates.

            (c) Delivery to Registered  Holder. As soon as practicable after the
exercise of this Warrant in whole or in part,  and in any event within three (3)
trading days thereafter, the Company, at its expense, will cause to be issued in
the name of, and  delivered to, the  Registered  Holder,  or as such  Registered
Holder (upon payment by such Registered Holder of any applicable transfer taxes)
may direct:

      (i)a certificate or certificates for the number of shares of Warrant Stock
to which such Registered Holder shall be entitled, and

      (ii) in case such  exercise  is in part only,  a new  warrant or  warrants
(dated the date hereof) of like tenor,  calling in the  aggregate on the face or
faces  thereof for the number of shares of Warrant Stock equal  (without  giving
effect to any adjustment therein) to the number of such shares called for on the
face of this Warrant minus the number of such shares purchased by the Registered
Holder upon such exercise as provided in Section 2(a) above.

      3.    Adjustments.

            (a) If  outstanding  shares of the Common Stock shall be  subdivided
into a greater number of shares,  or if a dividend in Common Stock shall be paid
in respect of Common Stock,  the Purchase Price in effect  immediately  prior to
such  subdivision  or at the record date of such dividend  shall  simultaneously
with the  effectiveness of such subdivision or immediately after the record date
of such dividend be  proportionately  reduced.  If outstanding  shares of Common
Stock shall be combined into a smaller  number of shares,  the Purchase Price in
effect  immediately  prior to such combination  shall,  simultaneously  with the
effectiveness  of such  combination,  be  proportionately  increased.  When  any
adjustment is required to be made in the Purchase Price, the number of shares of
Warrant Stock purchasable upon the exercise of this Warrant shall  automatically
be changed to equal the number determined by dividing (i) an amount equal to the
number of shares issuable upon the exercise of this Warrant immediately prior to
such adjustment, multiplied by the Purchase Price in effect immediately prior to
such  adjustment,  by (ii) the Purchase Price in effect  immediately  after such
adjustment.

            (b) In the case of any  reclassification  or change in the number of
outstanding  securities of the Company or in the case of any  reorganization  of
the Company (or any other  corporation  the stock or  securities of which are at
the time receivable upon the exercise of this Warrant) or any similar  corporate
reorganization  on or after  the date  hereof,  then and in each  such  case the
holder  of this  Warrant,  upon  the  exercise  hereof  at any  time  after  the
consummation  of  such  reclassification,   change,  reorganization,  merger  or
conveyance, shall be entitled to receive, in lieu of the

                                      2





stock or other securities and property receivable upon the exercise hereof prior
to such  consummation,  the stock or other  securities or property to which such
holder  would  have been  entitled  upon such  consummation  if such  holder had
exercised  this  Warrant  immediately  prior  thereto,  all  subject  to further
adjustment as provided in subsection  3(a);  and in each such case, the terms of
this Section 3 shall be  applicable  to the shares of stock or other  securities
properly receivable upon the exercise of this Warrant after such consummation.

            (c)  Issuance of Common  Stock  Below  Purchase  Price.  In case the
Company shall issue or sell shares of Common Stock or rights, options,  warrants
or convertible or exchangeable  securities containing the right to subscribe for
or  purchase  shares of Common  Stock  (other than upon  conversion  of Series A
Preferred Stock, exercise of a Warrant,  pursuant to an employee benefit plan or
in consideration  for the acquisition of the majority of the common stock or all
or  substantially  all  of  the  assets  of  another  business  entity),  in any
transaction  which is not  subject to the right of first  refusal  contained  in
Section 5 of that certain  Series A Preferred  Stock Purchase  Agreement,  dated
December 20, 1996, among the Company, Credit Suisse First Boston Corporation and
Silverton  International  Fund  Limited  at a price per  share of  Common  Stock
(determined,  in the  case  of  rights,  options,  warrants  or  convertible  or
exchangeable  securities,  by dividing  (A) the total amount  receivable  by the
Company in  consideration  of the  issuance  and sale of such  rights,  options,
warrants or convertible or exchangeable securities, plus the total consideration
payable to the Company upon exercise, conversion or exchange thereof, by (B) the
total number of shares of Common Stock covered by such rights, options, warrants
or convertible or  exchangeable  securities)  that is lower (at the date of such
sale or issuance) than the Purchase Price, or for no consideration, then in each
case the number of shares of Common Stock thereafter  issuable upon the exercise
of all Warrants then  outstanding  shall be increased in a manner  determined by
multiplying the number of shares of Common Stock  theretofore  issuable upon the
exercise of all Warrants then outstanding by a fraction,  of which the numerator
shall be the number of shares of Common Stock  outstanding  immediately prior to
the sale or  issuance  plus the  number of  additional  shares  of Common  Stock
offered for subscription or purchase or to be issued upon conversion or exchange
of such  convertible or  exchangeable  securities,  and of which the denominator
shall be the number of shares of Common Stock  outstanding  immediately prior to
the sale or  issuance  plus the  number  of shares  of  Common  Stock  which the
"aggregate  consideration  to be  received  by the  Company"  (as defined in the
following  paragraph) in connection with such sale or issuance would purchase at
the Purchase Price.

      For the purpose of such  adjustments  the "aggregate  consideration  to be
received  by the  Company"  therefor  shall be  deemed  to be the  consideration
received  by the  Company for such Common  Stock,  rights  options,  warrants or
convertible or exchangeable securities plus any consideration or premiums stated
in such rights,  options,  warrants or convertible or exchangeable securities to
be paid for the shares of Common Stock covered thereby.

      In case the Company  shall issue or sell shares of Common Stock or rights,
options, warrants or convertible or exchangeable securities containing the right
to  subscribe  for or  purchase  shares  of  Common  Stock  for a  consideration
consisting,  in whole or in part, of property other than cash or its equivalent,
then  in   determining   the  "price   per  share  of  Common   Stock"  and  the
"consideration"  receivable  by or payable to the Company  for  purposes of this
Section  3(c),  the Board of Directors of the Company shall  determine,  in good
faith, the fair value of such property. In case the Company shall issue and sell
rights,  options,  warrants or convertible or exchangeable securities containing
the right to subscribe for or purchase shares of Common Stock, together with one
or  more  other  securities  as part of a unit  at a  price  per  unit,  then in
determining  the  "price  per share of  Common  Stock"  and the  "consideration"
receivable by or payable to the Company for purposes of this Section  3(c),  the
Board of Directors of the Company shall determine, in good faith, the fair value
of the rights, options,  warrants or convertible or exchangeable securities then
being sold as part of such unit.

      Any  increase  of the  number  of shares of  Common  Stock  issuable  upon
exercise of all Warrants  then  outstanding  made  pursuant to this Section 3(c)
shall be allocated among such Warrants on a pro rata basis.

            (d) Expiration of Rights,  Options and Conversion  Privileges.  Upon
the expiration of any rights, options, warrants or conversion or exchange rights
that have previously  resulted in an adjustment  under this Section 3(c), if any
thereof  shall not have been  exercised,  the  number of shares of Common  Stock
issuable  upon the  exercise  of each  Warrant  shall be  readjusted  and  shall
thereafter, upon any future exercise, be such as they would have been had

                                      3





they been originally adjusted (or had the original adjustment not been required,
as the case may be) as if (i) the only shares of Common Stock so issued were the
shares of Common  Stock,  if any,  actually  issued or sold upon the exercise of
such rights,  options,  warrants or conversion or exchange  rights and (ii) such
shares of  Common  Stock,  if any,  were  issued  or sold for the  consideration
actually received by the Company upon such exercise plus the  consideration,  if
any,  actually  received by the Company for issuance,  sale or grant of all such
rights,  options,  warrants  or  conversion  or exchange  rights  whether or not
exercised;  provided  that  no  such  readjustment  shall  have  the  effect  of
decreasing  the number of shares  issuable  upon  exercise of each  Warrant by a
number  that is in excess of the  amount or number of the  adjustment  initially
made in respect of the issuance, sale or grant of such rights, options, warrants
or  conversion  or exchange  rights or shall have the effect of  decreasing  the
number of shares of Common  Stock that have been  issued  upon  exercise  of any
Warrants prior to the date of such readjustment.

            (e) Adjustment of Exercise  Price.  Whenever the number of shares of
Common Stock  purchasable  upon the  exercise of each  Warrant is  adjusted,  as
provided  in Section  3(c),  the  Purchase  Price of each share of Common  Stock
payable upon  exercise of such  Warrant  shall be adjusted by  multiplying  such
Purchase Price immediately prior to such adjustment by a fraction, the numerator
of which  shall be the  number  of shares  issuable  upon the  exercise  of each
Warrant immediately prior to such adjustment, and the denominator of which shall
be the number of shares so issuable immediately thereafter.

            (f) When  any  adjustment  is  required  to be made in the  Purchase
Price,  the Company shall promptly mail to the  Registered  Holder a certificate
setting forth the Purchase Price after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.  Such  certificate  shall also
set forth the kind and  amount of stock or other  securities  or  property  into
which this Warrant shall be  exercisable  following the occurrence of any of the
events specified in subsections 3(a) or (b) above.

            (g)  Subject to the  provisions  of  Section 8 hereof,  in the event
that, prior to the first  anniversary of the date hereof,  the Registered Holder
has converted any shares of Series A Preferred  Stock issued to such  Registered
Holder on the date  hereof  into  Common  Stock,  the number of shares of Common
Stock  issuable  upon the exercise of this Warrant shall be reduced by an amount
equal to 200 shares of Common  Stock (as  adjusted as provided  herein) for each
share of Series A Preferred Stock which has been converted into Common Stock.

      4.    Transfers.

            (a) This  Warrant  and all  rights  hereunder  are  being  issued in
connection   with  the  issuance  of  the  Series  A  Preferred  Stock  and  are
transferable,  in whole or in part,  only with the prior written  consent of the
Company, which consent will not be unreasonably withheld, and in compliance with
subsections  4(b)  through 4(d)  hereof,  upon  surrender of this Warrant with a
properly executed  assignment (in the form of Exhibit B hereto) at the principal
office of the Company.

            (b) Each holder of this Warrant  acknowledges  that this Warrant and
the Warrant Stock have not been registered  under the Securities Act, and agrees
not to sell, pledge,  distribute,  offer for sale, transfer or otherwise dispose
of this Warrant or any Warrant  Stock issued upon its exercise in the absence of
(i) an effective  registration  statement  under the  Securities  Act as to this
Warrant or the Warrant Stock and  registration or  qualification of this Warrant
or the Warrant Stock under any applicable blue sky or state  securities law then
in  effect,  or (ii) an  opinion  of  counsel,  reasonably  satisfactory  to the
Company,  that  such  registration  and  qualification  are not  required.  Each
certificate  or other  instrument  for Warrant Stock issued upon the exercise of
this  Warrant  shall  bear  a  legend  substantially  to the  foregoing  effect.
Notwithstanding  the  foregoing,  no such  registration  statement or opinion of
counsel  (unless  required by the transfer  agent of the Company with respect to
the  Warrant  Stock)  shall be required  (A) for any  transfer of any Warrant or
Warrant Stock in compliance  with Rule 144 or Rule 144A of the  Securities  Act;
(B) for any transfer of Warrants or Warrant Stock by a Registered Holder that is
a  partnership  or a  corporation  to (x) a partner  of such  partnership  or an
"affiliate"  (as such term is defined in Regulation D under the Securities  Act)
of such corporation (in which case no consent of the Company pursuant to Section
4(a) above shall be required),  (y) a retired  partner of such  partnership  who
retires  after  the  date  hereof  or (z) the  estate  of any  such  partner  or
shareholder;  or (C) for the transfer by gift,  will or intestate  succession by
any Registered Holder to his or her spouse or lineal descendants

                                      4





or  successors  or any  trust  for any of the  foregoing.  Each  holder  of this
Warrant,  by acceptance  hereof,  acknowledges  that the Warrant and the Warrant
Stock are being (and will be) acquired  solely for such holder's own account and
not as nominee for any other party, and for investment;  provided, however, that
in making  such  representation,  the holder  shall not be  required to hold the
Warrant or any Warrant Stock for any minimum or other specific  term,  except as
required by Federal and applicable state securities laws.

            (c) A Registered Holder shall deliver written notice of any transfer
of this Warrant  permitted  hereunder,  in the form of Exhibit B hereto,  to the
Company  within three (3) business days after such  transfer.  Such notice shall
include the name and address of the transferee of this Warrant. The Company will
maintain a register containing the names and addresses of the Registered Holders
of this Warrant, and the Company shall enter thereon the name and address of any
transferee  of this Warrant  within three (3) business days after its receipt of
written  notice thereof from the Registered  Holder.  Any Registered  Holder may
change such  Registered  Holder's  address as shown on the  warrant  register by
written notice to the Company requesting such change.

            (d)  Until  any  transfer  of this  Warrant  is made in the  warrant
register,  the Company may treat the  Registered  Holder of this  Warrant as the
absolute owner hereof for all purposes; provided, however, that if and when this
Warrant  is  properly  assigned  in blank,  the  Company  may (but  shall not be
required  to) treat the  bearer  hereof as the  absolute  owner  hereof  for all
purposes, notwithstanding any notice to the contrary.

      5. No  Impairment.  The Company  will not, by  amendment of its charter or
through reorganization,  consolidation,  merger, dissolution,  sale of assets or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this  Warrant,  but will (subject to Section 15 below) at
all times in good faith  assist in the carrying out of all such terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the holder of this Warrant against impairment.

     6.  Termination.  This Warrant (and the right to purchase  securities  upon
exercise  hereof)  shall  terminate  three (3) years  after the date hereof (the
"Expiration Date").


      7.    Notices of Certain Transactions.  In case:

            (a) the  Company  shall  take a record of the  holders of its Common
Stock (or other stock or securities at the time deliverable upon the exercise of
this  Warrant)  for the purpose of  entitling  or  enabling  them to receive any
dividend  or other  distribution,  or to receive any right to  subscribe  for or
purchase any shares of stock of any class or any other securities, or to receive
any other right,  to subscribe  for or purchase any shares of stock of any class
or any other securities, or to receive any other right, or

            (b)  of   any   capital   reorganization   of   the   Company,   any
reclassification  of the capital  stock of the  Company,  any  consolidation  or
merger of the Company,  any  consolidation or merger of the Company with or into
another  corporation  (other than a consolidation or merger in which the Company
is the surviving  entity),  or any transfer of all or  substantially  all of the
assets of the Company, or

            (c)   of the voluntary or involuntary dissolution,  liquidation  or
winding-up of the Company,
then,  and in each such case, the Company will mail or cause to be mailed to the
Registered Holder of this Warrant a notice  specifying,  as the case may be, (i)
the date on which a record  is to be taken  for the  purpose  of such  dividend,
distribution  or right,  and stating the amount and character of such  dividend,
distribution or right, or (ii) the effective date on which such  reorganization,
reclassification,  consolidation,  merger, transfer, dissolution, liquidation or
winding-up is to take place,  and the time,  if any is to be fixed,  as of which
the holders of record of Common Stock (or such other stock or  securities at the
time  deliverable  upon such  reorganization,  reclassification,  consolidation,
merger, transfer, dissolution,  liquidation or winding-up) are to be determined.
Such notice  shall be mailed at least  twenty (20) days prior to the record date
or effective date for the event specified in such notice.


                                      5





      8. Optional  Redemption.  If, at any time, the Company  delivers a written
redemption notice to the Registered  Holder under subsection  8(b)(i) of Article
III of the Articles of Incorporation of the Company, as amended,  with regard to
the shares of Series A Preferred Stock owned by Registered  Holder, the Company,
concurrently  with such  written  redemption  notice,  shall  deliver a separate
written notice to the Registered  Holder stating that the Registered  Holder has
ninety (90) days from the date such separate  written notice is delivered to the
Registered  Holder to exercise the Warrant for the Purchase Price or the Company
will  redeem the  Warrant  with  respect  to any shares of Warrant  Stock not so
converted at a purchase price of $.01 per  underlying  share of Warrant Stock on
the date  that is  thirty  (30) days  after  the date of such  separate  written
notice.  At the end of such ninety  (90) day period,  the Company may redeem the
Warrant with respect to any portion  thereof  that has not been  converted  into
shares of Warrant  Stock by  delivering  to the  Registered  Holder the purchase
price stated in this Section 8 with respect to such  unconverted  portion of the
Warrant via check or wire transfer. The ninety (90) day period set forth in this
Section 8 shall be extended by the number of days  during  which a  registration
statement is not effective or otherwise not available for use by the  Registered
Holders.

      9.  Reservation  of Stock.  The Company will at all times reserve and keep
available,  solely for the  issuance  and  delivery  upon the  exercise  of this
Warrant, such shares of Warrant Stock and other stock,  securities and property,
as from time to time shall be issuable upon the exercise of this Warrant.

      10. Exchange of Warrants.  Upon the surrender by the Registered  Holder of
any Warrant or  Warrants,  properly  endorsed,  to the Company at the  principal
office of the Company,  the Company will, subject to the provisions of Section 4
hereof, issue and deliver to or upon the order of such Registered Holder, at the
Company's  expense, a new Warrant or Warrants of like tenor, in the name of such
Registered  Holder or as such Registered Holder (upon payment by such Registered
Holder of any applicable transfer taxes) may direct, calling in the aggregate on
the face or faces thereof for the number of shares of Common Stock called for on
the face or faces of the Warrant or Warrants so surrendered.

      11.  Replacement  of  Warrants.   Upon  receipt  of  evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant and (in the case of loss, theft or destruction) upon delivery of an
indemnity agreement in an amount reasonably  satisfactory to the Company, or (in
the case of mutilation)  upon surrender and  cancellation  of this Warrant,  the
Company will issue, in lieu thereof, a new Warrant of like tenor.

      12. Notices.  Unless otherwise provided,  any notice required or permitted
under this  Warrant  shall be given in writing and  addressed to the party to be
notified at the address or facsimile  number  indicated for such party set forth
in the records of the Company for such  purpose or, in the case of the  Company,
at 1601 Forum  Place,  Suite 1110,  West Palm Beach,  Florida  33401,  attention
Daniel  Osborne,  Chief  Accounting  Officer,  or at such  other  address as any
Registered  Holder or the Company may  designate by giving ten (10) days advance
written  notice to all other  parties.  Such notice shall be deemed  effectively
given upon (i) personal delivery to the party to be notified or (ii) delivery by
overnight  courier  to the  party to be  notified  or (iii) on the  fifth  (5th)
business day following deposit with the United States Post Office, by registered
or  certified  mail,   postage  prepaid  or  (iv)  delivery  via  facsimile  and
confirmation generated by the sender's facsimile machine.

      13. No Rights as  Shareholder.  Until the  exercise of this  Warrant,  the
Registered  Holder of this  Warrant  shall not have or  exercise  any  rights by
virtue hereof as a shareholder of the Company solely by reason of being a holder
of this Warrant.

      14. No Fractional  Shares.  No  fractional  shares of Common Stock will be
issued in  connection  with any exercise  hereunder.  In lieu of any  fractional
shares which would  otherwise be issuable,  the Company  shall pay cash equal to
the product of such fraction multiplied by the fair market value of one share of
Common Stock on the date of exercise,  as determined by the average  closing bid
price,  as  reported  on the Nasdaq  National  Market  (or such other  principal
securities  market on which the shares of Common  Stock are  traded) of one such
share for the three (3) trading days immediately preceding the date of exercise.

      15. Amendment or Waiver. Any term of this Warrant may be amended or waived
upon written consent of the Company and all of the holders hereof.
