                                     WARRANT

                               Warrant to Purchase
                          66,667 Shares of Common Stock

                        Warrant to Purchase Common Stock
                      of Automated Light Technologies, Inc.

This  is  to  certify  that,  FOR  VALUE   RECEIVED,   CONNECTICUT   INNOVATIONS
INCORPORATED,  a Connecticut corporation, its successors ("Holder"), is entitled
to purchase,  subject to the provisions of this Warrant,  from  AUTOMATED  LIGHT
TECHNOLOGIES,  INC.,  a  Delaware  corporation  (the  "Company"),  at the  price
hereinafter  set forth,  66,667  shares of common  stock,  $,01 par value of the
Company  ("Common  Stock")  in  accordance  with the  schedule  and price  shown
hereunder,  at any time on or after 3:30 p.m. Eastern Standard Time on August 2,
1990 subject to the limitations set forth herein.

Section I. EXERCISE OF WARRANT. Subject to and in accordance with the provisions
of Section VI hereof,  this  Warrant may be exercised in whole or in part at any
time or from time to time on or after  August  2,  1990 but not later  than 3:30
p.m. Eastern Standard Time on September 1, 1996 or it September 1, 1996 is a day
on which banking  institutions are authorized by law to close,  then on the next
succeeding  day which shall not be such a day,  by  presentation  and  surrender
hereof to the Company with the Purchase  Form annexed  hereto duly  executed and
accompanied  by payment of the Exercise  Price with all federal and state taxes,
if any,  applicable  upon such exercise.  If this Warrant should be exercised in
part only,  the Company  shall,  upon  surrender  of this  Warrant,  execute and
deliver a new Warrant evidencing the right of the Holder to purchase the balance
of the shares purchasable hereunder. Upon receipt by the Company of this Warrant
at the  office of the  Company,  in proper  form for  exercise,  accompanied  by
payment of the Exercise  Price and  requisite  taxes,  if any, the Company shall
forthwith issue and deliver, or cause to be issued and delivered,  to the Holder
as soon as practicable,  but in any event within thirty (30) days, a certificate
or certificates for the shares of Common Stock issuable upon such exercise.  The
exercise of this Warrant shall be deemed to have been effected immediately prior
to the  close  of  business  on  the  business  day on  which  this  warrant  is
surrendered  to the  Company  and,  at such  time,  the person in whose name the
certificate for shares of


<PAGE>



Common Stock shall be issuable upon such exercise shall be deemed to have become
the holder of record of such Common Stock.

Section II. ADJUSTMENTS.

         (a) Adjustment for Stock Splits and Combinations.  If the Company shall
at any time, or from time to time,  after the date hereof,  effect a subdivision
of its  outstanding  capital  stock then,  at the option of the Holder,  (i) the
Exercise  Price (as  defined  below)  then in  effect  immediately  before  that
subdivision shall be  proportionately  decreased or (ii) the number of shares of
Common Stock  issuable upon  conversion of this Warrant (the "Number of Issuable
Shares") shall be  proportionately  increased,  and  conversely,  if the Company
shall at any time,  or from time to time,  after the date  hereof,  combine  its
outstanding  shares of Capital Stock, then, at the option of the Holder, (i) the
Exercise  Price  then in effect  immediately  before  the  combination  shall be
proportionately  increased  or (ii) the  Number  of  Issuable  Shares"  shall be
proportionately decreased. Any adjustment under this Subsection (a) shall become
effective  at the  close  of  business  on  the  day  any  such  subdivision  or
combination  becomes  effective.  In the event  that  Holder  fails to make such
election on or before the effective  date of such  subdivision  or  combination,
then Holder shall be deemed to have selected option (i).

         (b) Adjustment for Certain Dividends and Distributions.  If the Company
at any time, or from time to time, after the date hereof, shall make or issue or
fix a record date for the  determination of holders of Capital Stock entitled to
receive a dividend or other distribution payable in additional shares of Capital
Stock, then, and in each such event:

(i) the Exercise  Price then in effect shall be decreased as of the date of such
issuance  or, at the time or upon the event  such a record  date shall have been
fixed,  as of the close of business on such record date (the  "Record  Date") by
multiplying  the  Exercise  Price then in effect by a  fraction,  determined  as
follows:

         (x) the  numerator  of which  shall be the  total  number  of shares of
Capital Stock issued and outstanding  immediately  prior to the Record Date plus
the number of shares  that  Holder 1S  entitled  to upon full  exercise  of this
Warrant; and

         (y) the  denominator  of which  shall be the total  number of shares of
Capital Stock issued and outstanding  immediately  prior to the Record Date plus
the number of shares  that  Holder is  entitled  to upon full  exercise  of this
Warrant plus the number of shares of Capital  Stock  issuable in payment of such
dividend or distribution and

(ii) the  Number of  Issuable  Shares  shall be  increased  to equal the  number
derived by dividing $100,000.00 (or $100,000.00 less


<PAGE>



the price paid for any shares  purchased in a partial  exercise of this Warrant,
if applicable) by the adjusted Exercise Price after application of (i) above.

For purposes of this  Subsection  (b), if such Record Date shall have been fixed
and such dividend is not fully paid or if such distribution is not fully made on
the date fixed therefor, the Exercise Price or the Number of Issuable Shares, as
the case may be, shall be recomputed  accordingly as of the close of business on
such Record Date,  and  thereafter the Exercise Price and the Number of Issuable
Shares shall be adjusted  pursuant to this Subsection (b) as of the day and time
that each actual payment of such dividends or distributions is made.

         (c) Adjustment for Reclassification.  Exchange and Substitution. If the
Common Stock issuable upon the exercise hereof shall be changed into the same or
a  different  number  of shares of any class or  classes  of stock,  whether  by
reclassification,  exchange,  substitution or other  transaction  having similar
effect  (other than a subdivision  or  combination  of shares or stock  dividend
provided for above, or a reorganization, merger, consolidation or sale of assets
provided for elsewhere in this Section II) then and in each such event, upon the
exercise of this Warrant,  in lieu of shares of Common  Stock,  the Holder shall
have the right  thereafter to receive the kind and amount of shares of stock and
other securities and property receivable upon such  reclassification,  exchange,
substitution or other  transaction  having similar  effect,  as did or shall the
holders of shares of the Common Stock as of the day immediately prior to the day
that such reclassification, exchange or substitution is or becomes effective all
subject to further adjustment as provided in subparagraphs a, b, d and e herein,
if applicable.

         (d)  Reorganization.  Mergers,  Consolidations or Sale of Assets. If at
any  time,  or from time to time,  there  shall be  (other  than a  subdivision,
combination,  reclassification,  exchange,  substitution  of shares provided for
elsewhere  in this  Section II) a capital  reorganization  involving a merger or
consolidation  of the Company  with or into another  corporation  or the sale or
transfer (a "Sale") of all or substantially all of the Company's  properties and
assets to any other  person;  then,  as a part of such  reorganization,  merger,
consolidation or Sale adequate  provision shall be made so that the Holder shall
thereafter be entitled to receive, upon exercise hereof, the number of shares of
stock or other  securities  or  property  of the  Company,  or of the  successor
corporation,  resulting from such reorganization,  merger, consolidation or Sale
as to which a holder of Common  Stock  deliverable  upon the  ultimate  exercise
hereof  would  have  been  entitled  to  receive  as a  result  of such  capital
reorganization,  merger,  consolidation  or Sale. In the case of a Sale in which
the Company  receives  cash in payment of the  purchase  price,  then the Holder
shall be deemed to have exercised this Warrant immediately prior to the Sale and
shall receive a cash payment equal to that which a holder of Common


<PAGE>



Stock  deliverable upon the ultimate exercise hereof would have been entitled to
receive  as a result of such Sale less the  Exercise  Price.  In any such  case,
appropriate  adjustment  shall be made in the  application  of the provisions of
this   Section  II  with   respect  to  the  rights  of  the  Holder  after  the
reorganization,  merger, consolidation or Sale to the end that the provisions of
this Section II (including  adjustment of the Exercise  Price then in effect and
the number of shares  issuable upon exercise  hereof) shall be applicable  after
any such event as nearly equivalent as may be practicable.

         (e) Adjustment for Issuance of New Shares.  If the Company at any time,
or from time to time, after the date hereof,  shall issue  additional  shares of
Capital Stock not otherwise  described elsewhere in this Section at a price less
than the Exercise Price then in effect, then, and in each such event:

(i) the Exercise  Price then in effect shall be decreased as of the date of such
issuance (the "Issuance  Date") by multiplying the Exercise Price then in effect
by a fraction, determined as follows:

         (x) the  numerator  of which  shall be the  total  number  of shares of
Capital Stock issued  immediately  prior to the Issuance Date plus the number of
shares that Holder is entitled to upon full exercise of this Warrant; and

         (y) the  denominator  of which  shall be the total  number of shares of
Capital Stock issued  immediately  prior to the Issuance Date plus the number of
shares that Holder is entitled to upon full  exercise of this  Warrant  plus the
number of new shares issued as of the Issuance Date and

(ii) the  Number of  Issuable  Shares  shall be  increased  to equal the  number
derived by  dividing  $l00,000.00  (or  $100,000.00  less the price paid for any
shares  purchased in a partial  exercise of this Warrant,  if applicable) by the
adjusted Exercise Price after application of (i) above.

If the Company at any time,  or from time to time,  after the date hereof  shall
issue additional  shares of Capital Stock not otherwise  described  elsewhere in
this  Section at a price  equal to or greater  than the  Exercise  Price then in
effect,  then,  and in each such event the Number of  Issuable  Shares  shall be
increased to equal the number derived by multiplying  the number of shares which
Holder is  entitled  to purchase  pursuant  to this  Warrant by a fraction,  the
numerator of which shall be the total  number of shares of Capital  Stock issued
immediately  prior to the Issuance  Date plus the number of new shares issued as
of the Issuance Date and the  denominator  of which shall be the total number of
shares of Capital Stock issued  immediately  prior to the Issuance Date. If such
shares are issued at a price greater than Three Dollars (S3.00) per share,  then
the  Exercise  Price for the  additional  shares  which  Holder is  entitled  to
purchase as a result of the


<PAGE>



adjustment  set forth herein shall equal the issuance  price of such shares.  If
such  shares are issued at a price equal to or less than Three  Dollars  ($3.00)
per share,  then the Exercise  Price for the  additional  shares which Holder is
entitled to purchase as a result of the  adjustment set forth herein shall equal
the then existing  Exercise Price.  If, at the time a public offering is made of
the Capital Stock of the Company,  the Company  demonstrates  to Holder that the
provisions  of this  subsection  would have a  material,  adverse  impact on the
Company's ability to make such public offering, then Holder agrees that it shall
negotiate  in good faith with the  Company to amend this  subsection  to provide
Holder  with a  similar  position  to that  provided  by this  subsection  while
ameliorating the impediment to the public offering.

         Section III.  RESERVATION OF SHARES.  The Company hereby agrees that at
all times during the terms of this Warrant  there shall be reserved for issuance
such number of shares of its Common Stock as shall be required to be issued upon
exercise of this Warrant.

         Section IV. FRACTIONAL SHARES. This Warrant may be exercised only for a
whole  number  of  shares of  Common  Stock  and no  fractional  shares of scrip
representing  fractional  shares  shall be  issuable  upon the  exercise of this
Warrant.

         Section  V.  STOCKHOLDERS'  RIGHTS.  Until the valid  exercise  of this
Warrant and payment in full as provided  herein,  the holder hereof shall not be
entitled to any rights of a stockholder.

         Section VI. EXERCISE TIME AND PRICE.  This Warrant is exercisable on or
before  September 1, 1996 with respect to 66,667 shares of Common Stock at $1.50
per share (the "Exercise Price").

         Section VII. COMPLIANCE WITH SECURITIES ACT;  DISPOSITION OF WARRANT OR
SHARES OF COMMON STOCK; RIGHT OF FIRST REFUSAL; RESTRICTION ON TRANSFER

         (a)  Compliance  with  Securities  Act. The holder of this Warrant,  by
acceptance hereof, agrees that this Warrant and the shares of Common Stock to be
issued upon  exercise  hereof are being  acquired for  investment  and that such
holder will not offer,  sell or otherwise  dispose of this Warrant or any shares
of Common Stock to be issued upon  exercise  hereof  except under  circumstances
which will not result in a violation of the  Securities  Act of 1933, as amended
(the "Act").  This Warrant (to the extent  applicable)  and all shares of Common
Stock issued upon exercise of this Warrant  (unless  either is registered  under
the Act) shall be stamped or imprinted  with the  restrictive  legend as appears
hereon.


<PAGE>



         (b)  Disposition  of  Warrant  and  Shares.  Subject  to  subsection  d
hereinbelow,  with respect to any offer,  sale,  transfer,  assignment  or other
disposition of this Warrant or any shares of Common Stock  acquired  pursuant to
the exercise of this Warrant prior to  registration  of such shares,  the holder
hereof and each  subsequent  holder of the Warrant agrees to give written notice
to the Company prior thereto,  describing  briefly the manner thereof,  together
with the written opinion of counsel  satisfactory to the Company,  to the effect
that such offer, sale, transfer, assignment or other disposition may be effected
without  registration or  qualification  (under the Act as then in effect or any
federal or state law then in effect)  of this  Warrant or such  shares of Common
Stock and indicating  whether or not under the Act certificates for this Warrant
or such shares of Common Stock to be sold or  otherwise  disposed of require any
restrictive legend as to applicable  restrictions on transferability in order to
ensure  compliance with the Act. Each certificate  representing  this Warrant or
the shares of Common Stock thus transferred  (except a transfer pursuant to Rule
144) shall bear a legend as to the applicable  restriction on transferability in
order to ensure  compliance  with the Act,  unless in the  aforesaid  opinion of
counsel  satisfactory  to the  company,  such legend is not required in order to
ensure compliance with the Act. The Company may issue stop transfer instructions
to its transfer agent in connection with the foregoing restrictions.

         (c) Right of First Refusal. In the event that Holder receives bona fide
third party offer (the "Offer") to purchase this Warrant or any shares of Common
Stock acquired pursuant to the exercise of the Warrant prior to the registration
of such shares and desires to accept such offer,  then Holder  shall give notice
of such offer to the Company.  The Company shall have the right to purchase this
Warrant or any shares of Common Stock  acquired  pursuant to the exercise of the
Warrant on the same terms and  conditions as are set forth in the Offer.  If the
Company  elects to exercise  its rights to purchase the Warrant or the shares of
Common Stock,  it shall give notice of the same to the Holder within thirty (30)
days of the date of Holder's  notice to the  Company.  Failure of the Company to
provide such notice  within said thirty (30) days shall  terminate the Company's
right of first refusal with respect to the Offer.

         (d) Restriction on Transfer.  Holder agrees that, unless the Company is
in default after  expiration of applicable cure and grace periods under the loan
made by  Holder  to the  Company  as of the date  hereof  and such loan has been
accelerated by CII, it shall not have the right to sell, transfer or assign this
Warrant to a competitor of the Company.  For the purposes  hereof, a "competitor
of the Company"  shall be any person or entity that  develops,  manufactures  or
markets  systems for the  monitoring of or the locating of breaks and damages in
fiber optic and/or  copper lines or any other system or systems  currently or in
the future developed, manufactured or marketed by the Company.

         Section  VIII.  REPLACEMENT  OF  WARRANTS.  Upon  receipt  of  evidence
reasonably  satisfactory  to the  Company  of the loss,  theft,  destruction  or
mutilation of the Warrant or any subsequent  Warrant and receipt of an indemnity
agreement  reasonably  satisfactory to the Company, the Company, at its expense,
will execute and deliver a new Warrant of like tenor.

         Section  IX.  APPLICABLE  LAW.  This  Warrant  shall be governed by and
construed in accordance with the laws of the State of Connecticut.
