                           DESTRON FEARING CORPORATION

                              AMENDED AND RESTATED
                     NONEMPLOYEE DIRECTOR STOCK OPTION PLAN
                 (amended and restated as of February 17, 2000)

I.      Purpose

     The Destron Fearing Corporation Nonemployee Director Stock Option Plan (the
"Plan")  provides  for the grant of Stock  Options to  Nonemployee  Directors of
Destron Fearing Corporation (the "Company") in order to advance the interests of
the Company through the motivation,  attraction and retention of its Nonemployee
Directors.

II.     Non-Incentive Stock Options

     The Stock  Options  granted  under  the Plan  shall be  nonstatutory  stock
options  ("NSOs")  which are  intended  to be  options  that do not  qualify  as
"incentive  stock  options"  under  Section 422 of the Internal  Revenue Code of
1986, as amended (the "Code").

III.    Administration

     3.1.  Committee. The Plan shall be administered by the  Board of  Directors
of the Company  (the  "Board") or by a committee of two or more  directors  (the
"Committee").  The  Committee or the Board,  as the case may be, shall have full
authority to administer the Plan,  including authority to interpret and construe
any provision of the Plan and any Stock Option granted thereunder,  and to adopt
such rules and regulations for  administering  the Plan as it may deem necessary
in order to comply with the  requirements  of the Code or in order to conform to
any regulation or to any change in any law or regulation applicable thereto. The
Board of  Directors  may reserve to itself any of the  authority  granted to the
Committee  as set forth  herein,  and it may  perform and  discharge  all of the
functions  and  responsibilities  of  the  Committee  at  any  time  that a duly
constituted  Committee is not appointed and serving. All references in this Plan
to the "Committee"  shall be deemed to refer to the Board of Directors  whenever
the Board is discharging the powers and responsibilities of the Committee.

     3.2.  Actions  of Committee.  All actions taken and all interpretations and
determinations made by the Committee in good faith (including  determinations of
Fair Market Value) shall be final and binding upon all Participants, the Company
and all other interested persons. No member of the Committee shall be personally
liable for any action,  determination or interpretation  made in good faith with

                                       1
<PAGE>

respect to the Plan,  and all  members of the  Committee  shall,  in addition to
their rights as directors, be fully protected by the Company with respect to any
such action, determination or interpretation.

IV.      Definitions

     4.1.  "Stock Option." A Stock Option is the right granted under the Plan to
a Nonemployee  Director to purchase,  at such time or times and at such price or
prices  ("Option  Price") as are determined  pursuant to the Plan, the number of
shares of Common Stock determined pursuant to the Plan.

     4.2.  "Common  Stock." A share of Common Stock means a share of  authorized
but unissued or reacquired Common Stock (no par value) of the Company.

     4.3.  "Fair Market Value." If the Common Stock is not traded  publicly, the
Fair Market Value of a share of Common Stock on any date shall be determined, in
good faith, by the Board or the Committee after such  consultation  with outside
legal,  accounting  and other  experts  as the Board or the  Committee  may deem
advisable, and the Board or the Committee shall maintain a written record of its
method of determining  such value. If the Common Stock is traded  publicly,  the
Fair Market Value of a share of Common Stock on any date shall be the average of
the  representative  closing  bid and asked  prices,  as quoted by the  National
Association  of Securities  Dealers  through  NASDAQ (its  automated  system for
reporting quotes), for the date in question or, if the Common Stock is listed on
the NASDAQ National Market System or is listed on a national stock exchange, the
officially quoted closing price on NASDAQ or such exchange,  as the case may be,
on the date in question.

     4.4.  "Nonemployee  Director." A Nonemployee  Director is a director of the
Company who is not also an employee of the Company.

     4.5.  "Participant."   A  Participant is a  Nonemployee  Director to whom a
Stock Option is granted.

V.      Option Grants

     5.1.  Number of Shares.  Upon the  initial  election  or  appointment  of a
Nonemployee  Director  to the  Company's  Board of  Directors,  the  Nonemployee
Director  shall be granted  Stock  Options to purchase  15,000  shares of Common
Stock (subject to adjustment pursuant to Section 6.2 hereof) effective as of the
date such person is elected or appointed to the Board of Directors.  Thereafter,
effective  as of the date on which  such  person  is  reelected  to the Board of
Directors by the Company's shareholders,  (i) each Nonemployee Director who does
not hold the title of Chairman of the Company  shall be granted Stock Options to
purchase 5,000 shares of Common Stock (subject to adjustment pursuant to Section

                                       2
<PAGE>

6.2 hereof),  and (ii) the Nonemployee  Director who holds the title of Chairman
of the  Company  shall be granted a stock  option to purchase  10,000  shares of
Common Stock (subject to adjustment pursuant to Section 6.2 hereof).

     5.2.  Price. The purchase price per share of Common Stock for the shares to
be  purchased  pursuant to the exercise of any Stock Option shall be 100% of the
Fair  Market  Value  of a  share  of  Common  Stock  on the  date on  which  the
Nonemployee  Director  receiving  the Stock  Option  is  elected,  appointed  or
reelected to the Board of Directors, as the case may be.

     5.3.  Other Terms. Except for the limitations set forth in Sections 5.1 and
5.2, the terms and provisions of Stock Options shall be as determined  from time
to time by the  Committee,  and each Stock Option  issued may contain  terms and
provisions different from other Stock Options granted to the same or other Stock
Option  recipients.  Each Stock Option shall be evidenced by a written agreement
("Option  Agreement")  containing such terms and provisions as the Committee may
determine, subject to the provisions of the Plan.

VI.     Shares of Common Stock Subject to the Plan

     6.1.  Maximum Number.  The maximum  aggregate  number  of shares  of Common
Stock that may be made subject to Stock Options shall be 300,000  authorized but
unissued shares.  If any shares of Common Stock subject to Stock Options are not
purchased or otherwise  paid for before such Stock Options  expire,  such shares
may again be made subject to Stock Options.

     6.2.  Capital  Changes.  In the event any changes are made to the shares of
Common  Stock  (whether  by reason  of  merger,  consolidation,  reorganization,
recapitalization,  stock  dividend in excess of ten percent  (10%) at any single
time,  stock  split,  combination  of  shares,  exchange  of  shares,  change in
corporate structure or otherwise), appropriate adjustments shall be made in: (i)
the number of shares of Common Stock  theretofore made subject to Stock Options,
and in the  purchase  price of said  shares;  and (ii) the  aggregate  number of
shares  which may be made  subject  to Stock  Options.  If any of the  foregoing
adjustments   shall  result  in  a  fractional  share,  the  fraction  shall  be
disregarded,  and the Company shall have no obligation to make any cash or other
payment with respect to such a fractional share.

VII.    Exercise of Stock Options

     7.1.  Time  of  Exercise.  Subject  to  the  provisions  of the  Plan,  the
Committee, in its discretion, shall determine the time when a Stock Option, or a
portion of a Stock Option, shall become exercisable. Such time or times shall be
set forth in the  Option  Agreement  evidencing  such  Stock  Option.  All Stock
Options shall expire, to the extent not exercised,  five years after the date on
which  it  was  granted.  The  Committee  may  accelerate  the  vesting  of  any
Participant's  Stock Option by giving  written notice to the  Participant.  Upon
receipt of such notice,  the  Participant and the Company shall amend the Option

                                       3
<PAGE>

Agreement to reflect the new vesting schedule.  The acceleration of the exercise
period of a Stock  Option  shall not  affect the  expiration  date of that Stock
Option.

     7.2.  Exchange of Outstanding Stock. The Committee, in its sole discretion,
may permit a  Participant  to  surrender  to the Company  shares of Common Stock
previously  acquired by the Participant as part or full payment for the exercise
of a Stock Option.  Such surrendered shares shall be valued at their Fair Market
Value on the date of exercise.

     7.3.  Use of Promissory  Note.  The Committee may, in its sole  discretion,
impose terms and  conditions,  including  conditions  relating to the manner and
timing of payments,  on the exercise of Stock Options. Such terms and conditions
may include,  but are not limited to, permitting a Participant to deliver to the
Company his  promissory  note as full or partial  payment for the  exercise of a
Stock Option.

     7.4. Stock Restriction Agreement.  The Committee may provide that shares of
Common Stock  issuable upon the exercise of a Stock Option shall,  under certain
conditions,  be subject to restrictions whereby the Company has a right of first
refusal with respect to such shares or a right or obligation  to repurchase  all
or a portion of such shares, which restrictions may survive a Participant's term
as a director of the Company. The acceleration of time or times at which a Stock
Option becomes  exercisable may be conditioned upon the Participant's  agreement
to such restrictions.

     7.5.  Termination of Director  Status Before  Exercise.  If a Participant's
term as a director  of the Company  shall  terminate  for any reason,  any Stock
Option  then  held  by  the  Participant  shall  remain  exercisable  after  the
termination of his director  status for the full term of the Stock Option.  If a
Stock Option is not  exercised  during its term, it shall be deemed to have been
forfeited and of no further force or effect.

     7.6.  Disposition of Forfeited  Stock  Options.  Any shares of Common Stock
subject to Stock  Options  forfeited by a  Participant  shall not  thereafter be
eligible for  purchase by the  Participant  but may be subject to Stock  Options
granted to other Participants.

VIII.   No Effect Upon Stockholder Rights

     Nothing  in this  Plan  shall  interfere  in any way with the  right of the
stockholders of the Company to remove the Participant from the Board pursuant to
Canadian law and the Company's Certificate of Incorporation and Bylaws.

                                       4
<PAGE>

IX.     No Rights as a Stockholder

     A  Participant  shall have no rights as a  stockholder  with respect to any
shares of Common Stock subject to a Stock Option.  Except as provided in Section
6.2, no adjustment  shall be made in the number of shares of Common Stock issued
to a Participant,  or in any other rights of the Participant  upon exercise of a
Stock Option by reason of any dividend,  distribution  or other fight granted to
stockholders  for which the record  date is prior to the date of exercise of the
Participant's Stock Option.

X.      Assignability

     No Stock Option granted under this Plan, nor any other rights acquired by a
Participant   under  this  Plan,  shall  be  assignable  or  transferable  by  a
Participant,  other  than by will or the laws of  descent  and  distribution  or
pursuant to a qualified domestic relations order as defined by the Code, Title I
of  the  Employee  Retirement  Income  Security  Act  ("ERISA"),  or  the  rules
thereunder.  In the event of the  Participant's  death,  the Stock Option may be
exercised by the Personal  Representative of the Participant's  estate or, if no
Personal  Representative  has been appointed,  by the successor or successors in
interest determined under the Participant's will or under the applicable laws of
descent and distribution.

XI.     Merger or Liquidation of the Company

     If the Company or its  stockholders  enter into an  agreement to dispose of
all, or  substantially  all, of the assets or  outstanding  capital stock of the
Company  by means of a sale or  liquidation,  or a merger or  reorganization  in
which  the  Company  is  not  the  surviving  corporation,   all  Stock  Options
outstanding  under the Plan as of the day before the  consummation of such sale,
liquidation,  merger or reorganization,  to the extent not exercised,  shall for
all  purposes  under this Plan become  exercisable  in full as of such date even
though the dates of  exercise  established  pursuant to Section 7.1 have not yet
occurred,  unless the Board shall have prescribed  other terms and conditions to
the exercise of the Stock Options, or otherwise modified the Stock Options.

XII.    Amendment

     The Board may from time to time alter,  amend,  suspend or discontinue  the
Plan, including,  where applicable,  any modifications or amendments as it shall
deem advisable in order to conform to any regulation or to any change in any law
or regulation applicable thereto;  provided,  however, that no such action shall
adversely  affect the rights and  obligations  with' respect to Stock Options at
any time  outstanding  under the Plan; and provided  further that no such action
shall,  without the approval of the stockholders of the Company,  (i) materially
increase  the maximum  number of shares of Common Stock that may be made subject
to Stock Options (unless necessary to effect the adjustments required by Section
6.2), (ii) materially  increase the benefits accruing to Participants  under the
Plan,  or  (iii)  materially  modify  the  requirements  as to  eligibility  for

                                       5
<PAGE>

participation in the Plan. Subject to the foregoing, the provisions of Article V
of the Plan which set forth the number of shares of Common Stock for which Stock
Options shall be granted, the timing of Stock Option grants and the Stock Option
exercise  price shall not be amended  more than once every six (6) months  other
than to comport with changes in the Code, ERISA, or the rules thereunder.

XIII.   Registration of Optioned Shares

     The Stock  Options  shall not be  exercisable  unless the  purchase of such
optioned shares is pursuant to an applicable  effective  registration  statement
under the  Securities  Act of 1933,  as amended (the "Act"),  or unless,  in the
opinion of counsel to the Company, the proposed purchase of such optioned shares
would be  exempt  from  the  registration  requirements  of the Act and from the
registration or qualification requirements of applicable state securities law.

XIV.    Brokerage Arrangements

     The Committee,  in its discretion,  may enter into arrangements with one or
more  banks,   brokers  or  other  financial   institutions  to  facilitate  the
disposition of shares acquired upon exercise of Stock Options including, without
limitation, arrangements for the simultaneous exercise of Stock Options and sale
of the shares acquired upon such exercise.

XV.     Nonexclusivity of the Plan

     Neither  the  adoption of the Plan by the Board nor the  submission  of the
Plan to  stockholders of the Company for approval shall be construed as creating
any  limitations  on the power or  authority of the Board to adopt such other or
additional  compensation  arrangements  of whatever nature as the Board may deem
necessary or desirable or preclude or limit the  continuation of any other plan,
practice or arrangement  for the payment of  compensation  or fringe benefits to
Nonemployee Directors, which the Company now has lawfully put into effect.

XVI.    Effective Date

     This Plan was adopted by the Board of Directors and became effective on May
21, 1992 and was approved by the Company's shareholders on July 31, 1992.

the other appurtenant rights, powers and privileges hereinafter described.  This
Warrant is one of one or more  warrants  (the  "Warrants")  of the same form and
having the same terms as this Warrant.

                  Certain terms used in this Warrant are defined in Article V.

                                    ARTICLE I

                              EXERCISE OF WARRANTS

                  1.1 Method of Exercise.  To exercise  this Warrant in whole or
in part,  the Holder  shall  deliver to the  Company,  (a) this  Warrant,  (b) a
written notice,  in substantially  the form of the Subscription  Notice attached
hereto, of such Holder's  election to exercise this Warrant,  which notice shall
specify the number of shares of Common Stock to be purchased,  the denominations
of the share  certificate or  certificates  desired,  the name or names in which

be  exercisable  only,  to the extent and at the time or times,  that the Holder
could legally take possession and title of such shares. Payment made pursuant to
clause (c) above may be made,  at the option of the Holder:  (x) by cash,  money
order,  certified or bank cashier's check or wire transfer, (y) the surrender to
the Company of securities  of the Company  having a value equal to the aggregate
Exercise Price, as determined in good faith by the Company's board of directors,
or (z) the  delivery  of a notice to the Company  that the Holder is  exercising
this Warrant by authorizing the Company to reduce the number of shares of Common
Stock subject to this Warrant by the number of shares having an aggregate  value
equal to the  aggregate  Exercise  Price,  as  determined  in good  faith by the
Company's board of directors.

                  The Company shall, as promptly as practicable and in any event
within  three  Business  Days  thereafter,  execute  and  deliver or cause to be
executed and  delivered,  in  accordance  with such  notice,  a  certificate  or
certificates  representing  the  aggregate  number  and type of shares of Common
Stock  specified  in said  notice.  The share  certificate  or  certificates  so
delivered shall be in such  denominations as may be specified in such notice or,
if such notice  shall not specify  denominations,  shall be in the amount of the
number of shares of Common Stock for which the Warrant is being  exercised,  and
shall be issued in the name of the  Holder or such  other name or names as shall
be  designated  in such notice,  subject to Section  1.4.  Such  certificate  or
certificates  shall be deemed to have been issued,  and such Holder or any other
Person so  designated  to be named  therein  shall be deemed for all purposes to
have become a holder of record of such shares, as of the date the aforementioned
notice is received by the  Company.  If this Warrant  shall have been  exercised
only in part, the Company shall,  at the time of delivery of the  certificate or
certificates,  deliver  to the  Holder a new  Warrant  evidencing  the rights to
purchase the remaining shares of Common Stock called for by this Warrant,  which
new Warrant shall in all other respects be identical  with this Warrant,  or, at
the  request of the Holder,  appropriate  notation  may be made on this  Warrant
which shall then be returned to the Holder.  The Company shall pay all expenses,
taxes and other charges payable in connection with the preparation, issuance and
delivery of share  certificates  and new Warrants (other than the Holder's legal
and accounting fees and  disbursements),  except that, if share  certificates or
new Warrants shall be registered in the name or names other than the name of the
Holder,  funds  sufficient to pay all transfer taxes payable as a result of such
transfer   shall  be  paid  by  the  Holder  at  the  time  of  delivering   the
aforementioned  notice of exercise of promptly upon receipt or a written request
of the Company for payment.

                  1.2 Shares To Be Fully Paid and  Nonassessable.  All shares of
Common Stock issued upon the exercise of this Warrant  shall be validly  issued,
fully  paid  and  nonassessable  and  free  from all  preemptive  rights  of any
stockholder,  and from all taxes,  liens and charges  with  respect to the issue
thereof (other than transfer taxes).

                  1.3 No Fractional  Shares To Be Issued.  The Company shall not
be required to issue  fractions of shares of Common Stock upon  exercise of this
Warrant.  If any fraction of a share would,  but for this  Section,  be issuable
upon any exercise of this Warrant,  and if the Company shall have elected not to
issue such  fraction of a share,  in lieu of such  fractional  share the Company
shall pay to the Holder,  in cash,  an amount equal to such fraction of the Fair

                                       2
<PAGE>

Market  Value  per  share of  outstanding  Common  Stock of the  Company  on the
Business Day immediately prior to the date of such exercise.

                  1.4 Share Legend.  Each certificate for shares of Common Stock
issued upon exercise of this Warrant, unless at the time of exercise such shares
are registered under the Securities Act, shall bear the following legend:

                  "This  Security has not been  registered  under the Securities
                  Act of 1933, as amended,  or under the securities  laws of any
                  state or other  jurisdiction and may not be sold,  offered for
                  sale or otherwise  transferred  unless registered or qualified
                  under said Act and applicable  state securities laws or unless
                  the  Company   receives  an  opinion  of  counsel   reasonably
                  satisfactory to the Company that  registration,  qualification
                  or other such  actions are not  required  under said Act.  The
                  offering of this Security has not been reviewed or approved by
                  any state securities administrator."

                  Any certificate issued at any time in exchange or substitution
for any certificate  bearing such legend (except a new  certificate  issued upon
completion of a public distribution  pursuant to a registration  statement under
the  Securities  Act)  shall also bear such  legend  unless,  in the  opinion of
counsel  selected by the holder of such  certificate  (who may be an employee of
such holder) reasonably  satisfactory to the Company, the securities represented
thereby are no longer  subject to  restrictions  on resale under the  Securities
Act.

                  1.5 Reservation;  Authorization.  The Company has reserved and
will keep  available for issuance upon exercise of the Warrants the total number
of shares of Common Stock deliverable upon exercise of all Warrants from time to
time  outstanding.  The  issuance  of such  shares  has been  duly  and  validly
authorized  and,  when issued and sold in  accordance  with the  Warrants,  such
shares will be duly and validly issued, fully paid and nonassessable.

                                   ARTICLE II

                               TRANSFER, EXCHANGE
                           AND REPLACEMENT OF WARRANTS

                  2.1  Ownership of Warrant.  The Company may deem and treat the
Person in whose name this Warrant is  registered  as the holder and owner hereof
(notwithstanding  any  notations  of  ownership  or writing  hereon  made by any
Person)  for all  purposes  and  shall  not be  affected  by any  notice  to the
contrary,  until  presentation  of this Warrant for  registration of transfer as
provided in this Article II.

                  2.2  Transfer of Warrant. The Company agrees to maintain books
for the registration of transfers of the Warrants,  and transfer of this Warrant
and all  rights  hereunder  shall be  registered,  in whole or in part,  on such
books,  upon  surrender  of this  Warrant at the  headquarters  of the  company,
together  with a written  assignment of this Warrant duly executed by the Holder

or his duly  authorized  agent or  attorney,  with  (unless  the  Holder  is the
original  Warrantholder)  signatures  guaranteed by a bank or trust Company or a
broker  or dealer  registered  with the NASD,  and funds  sufficient  to pay any
transfer  taxes  payable upon such  transfer.  Upon  surrender the Company shall
execute and deliver a new Warrant or Warrants in the name of the  assignees  and
in the denominations specified in the instrument of assignment, and this Warrant
shall  promptly be canceled.  The Company  shall not be required to register any
transfers in violation of Section 2.6 hereof,  or if the Holder fails to furnish
to the  Company,  after a request  therefor,  an opinion  of counsel  reasonably
satisfactory  to the Company that such transfer is exempt from the  registration
requirements of the Securities Act.

                  2.3  Division or Combination of Warrants.  This Warrant may be
divided or combined with other Warrants upon surrender hereof and of any Warrant
or Warrants  with which this Warrant is to be combined at the Company,  together
with a written notice  specifying the names and  denominations  in which the new
Warrant or Warrants are to be issued,  signed by the holders  hereof and thereof
or their respective duly authorized  agents or attorneys.  Subject to compliance
with  Section 2.6 as to any  transfer  which may be involved in the  division or
combination,  the Company shall execute and deliver a new Warrant or Warrants in
exchange  for the Warrant or  Warrants  to be divided or combined in  accordance
with such notice.

                  2.4  Loss, Theft, Destruction or Mutilation of Warrants.  Upon
receipt of evidence satisfactory to the Company of the loss, theft,  destruction
or  mutilation  of any  Warrant  and,  in the  case of any such  loss,  theft or
destruction,  upon receipt of indemnity or security  reasonably  satisfactory to
the  Company,  or, in the in case of any such  mutilation,  upon  surrender  and
cancellation of such Warrant, the Company will make and deliver, in lieu of such
lost,  stolen,  destroyed or mutilated  Warrant, a new Warrant of like tenor and
representing the right to purchase the same aggregate number of shares of Common
Stock as provided for in such lost, stolen, destroyed or mutilated Warrant.

                  2.5  Expenses of Delivery of Warrants.  The Company  shall pay
all expenses,  taxes (other than transfer  taxes or income taxes of a Holder and
such Holder's  legal and  accounting  fees and  disbursement)  and other charges
payable in connection  with the  preparation,  issuance and delivery of Warrants
and shares issuable upon exercise of the Warrants hereunder.

                  2.6  Restrictions on Transfer and Division.  This Warrant, and
any  Warrants  resulting  from the  division,  transfer or  combination  of this
Warrant,  and the rights of a  Warrantholder  hereunder or  thereunder,  and any
shares of Common Stock  acquired by the exercise  hereof or thereof,  may not be
assigned or  transferred  to such persons as are determined in good faith by the
Company to be  competitors  of the  Company.  Such  restriction  shall not apply
following a public offering of Common Stock. No division, assignment or transfer
of the rights of a Warrantholder under a Warrant shall be effective with respect
to other than whole shares of Common Stock,  unless such  assignment or transfer
is of all of the  rights of such  Warrantholder  under such  Warrant;  provided,
however, that if this Warrant is originally exercisable with respect to a number
of shares of Common Stock that includes a fractional  share, this Warrant may be
divided such that such fractional share, together with one or more whole shares,
may be acquired by the exercise of a Warrant  resulting from such division.  The
term  "competitor"  shall  mean  (i)  any  person  (other  than  DTI)  providing

                                       4
<PAGE>

telecommunications  or fiber  optic  transmission  services,  (ii)  any  utility
Company,  (iii) KLT Inc. and (iv) any Affiliate,  director,  officer,  member or
partner of any of the foregoing.

                                   ARTICLE III

                                 CERTAIN RIGHTS

                  3.1 Contest and Appraisal Rights.  Upon each  determination of
Fair  Market  Value for an  adjustment  pursuant  to  Article  IV (other  than a
determination  relating solely to setting the value of fractional  shares),  the
Company shall promptly give notice thereof to all Warrantholders,  setting forth
in reasonable  detail the  calculation  of such Fair Market Value and the method
and basis of determination thereof, as the case may be. If the Requisite Holders
shall disagree with such determination and shall, by notice to the Company given
within  15 days  after the  Company's  notice  of such  determination,  elect to
dispute such  determination,  such dispute shall be resolved in accordance  with
this  Section  3.1.  In the event that a  determination  of Market  Price,  or a
determination  of Fair Market Value solely  involving Market Price, is disputed,
such  dispute  shall be  submitted  to a New York  Stock  Exchange  member  firm
selected  by  the  Company  and   acceptable   to  the   Warrantholders,   whose
determination  of Fair Market Value  and/or  Market  Price,  as the case may be,
shall be  binding  on the  Company  and the  Warrantholders.  The  costs of such
submission  shall  be  borne  by the  Warrantholders  electing  to  dispute  the
Company's determination, except that if such firm's determination of Fair Market
Value  and/or  Market  Price is  disparate  by 10% or more to the benefit of the
Warrantholders  from  the  Company's  original   determination,   the  costs  of
conducting  such submission  shall be borne by the Company.  In the event that a
determination of Fair Market Value, other than a determination  solely involving
Market Price, is disputed,  such dispute shall be resolved through the Appraisal
Procedure.

                  3.2 Certain  Covenants.  (a) The  Company covenants and agrees
that,  until exercise or cancellation of this Warrant,  the Company will deliver
to each Holder:

                           (i) As soon as  available  but not later than  ninety
         (90)  days  after  the  close  of the  fiscal  year of the  Company,  a
         consolidated  balance  sheet of the  Company as at the end of such year
         and the related consolidated and consolidating statements of income, of
         stockholders' equity and of cash flows for such year, such consolidated
         statements  to be audited  by  Deloitte & Touche LLP or other "Big Six"
         accounting firm;

                           (ii) As soon as  available  but not later  than sixty
         (60) days after the end of each quarter,  a consolidated  balance sheet
         of  the  Company  as at  the  end  of,  and  the  related  consolidated
         statements of income, of stockholders' equity and of cash flows for the
         portion of the Company's fiscal year then elapsed;

                  (b) By acceptance  of the  information  delivered  pursuant to
Section  3.2(a),  the  Holder  shall  be  deemed  to have  agreed  to hold  such
information in strict  confidence,  except as required by law,  unless and until
such information otherwise becomes publicly available. The Company may condition

                                       5
<PAGE>

the delivery of  information  pursuant to Section  3.2(a) upon the receipt of an
agreement executed by the Holder agreeing to the foregoing obligation.

                  (c) The  obligations  in Section  3.2(a)  shall cease upon the
Company  becoming  subject  to Section  12 or  Section  15(d) of the  Securities
Exchange Act of 1934, as amended.

                  3.3 Non-Disclosure. (a) In the event that the holder of shares
of Common Stock issued upon the exercise of this Warrant requests or demands, as
a shareholder of the Company,  to inspect,  examine or copy any of the Company's
books, records or other documentation or information, and the Board of Directors
of  the  Company  makes  a  good  faith   determination  that  such  inspection,
examination  or copying  would place the Company at a  competitive  disadvantage
with respect to any other entity, including but not limited to such shareholder,
that then  competes,  or is  reasonably  likely to  compete  in the  foreseeable
future,  either directly or indirectly,  with the Company,  then the Company may
refuse to disclose to such  shareholder any or all of the following items of the
Company:

                  (i)      interoffice  or  intraoffice  communication separated
                           solely for management review;

                  (ii)     confidential    analyses,    plans    for    business
                           development, organizational data, marketing plans and
                           strategies, or sales data;

                  (iii)    draft or  interim  financial  reports,  or any  other
                           internal  documents  subject to audit,  adjustment or
                           verification;

                  (iv)     unpublished  promotional  material,  cost and pricing
                           information,   customer  lists,  and  contracts,   in
                           whatever   form,   manner  or  medium   recorded  (if
                           recorded);

                  (v)      documentation  or  information  including,   but  not
                           limited  to, any and all  information  and  materials
                           that contain, or could lead to the disclosure of, the
                           Company's  trade  secrets  or  any  documentation  or
                           information concerning the Company's current,  future
                           or proposed  products or services,  including without
                           limitation  unpublished  computer  code (both  source
                           code  and  object  code),   network   configurations,
                           software  designs,  or any drawings,  specifications,
                           notebook  entries,  technical  notes and  graphs,  or
                           research; and

                  (vi)     all  other   information  that  the  Company  or  its
                           Affiliates  or  subsidiaries  treat  or  maintain  as
                           confidential, proprietary, restricted or otherwise as
                           not to be disclosed generally.

                  (b)      The  Warrantholder further agrees  that  all  of  the
above-mentioned  materials  do not  constitute  "books and  records"  within the

                                       6
<PAGE>

meaning of Section  351.215 of the Revised  Statutes of  Missouri,  and that the
Warrantholder  has no right or privilege by reason of becoming a shareholder  in
the Company to inspect, examine or copy such materials.

                                   ARTICLE IV

                             ANTIDILUTION PROVISIONS

                  4.1 Adjustments  Generally.  The Exercise Price and the number
of shares  of Common  Stock (or other  securities  or  property)  issuable  upon
exercise of this Warrant shall be subject to  adjustment  from time to time upon
the occurrence of certain events, as provided in this Article IV.

                  4.2 Common Stock  Reorganization.  If the Company  shall after
the date of issuance of this Warrant subdivide its outstanding  shares of Common
Stock into a greater number of shares or consolidate its  outstanding  shares of
Common  Stock into a smaller  number of shares  (any such event  being  called a
"Common Stock  Reorganization"),  then (a) the Exercise Price shall be adjusted,
effective  immediately  after the record  date at which the holders of shares of
Common Stock are determined for purposes of such Common Stock Reorganization, to
a price determined by multiplying the Exercise Price in effect immediately prior
to such record date by a fraction, the numerator of which shall be the number of
shares of Common Stock  outstanding  on such record date before giving effect to
such  Common  Stock  Reorganization  and the  denominator  of which shall be the
number of shares of Common Stock  outstanding after giving effect to such Common
Stock  Reorganization,  and (b) the number of shares of Common Stock  subject to
purchase  upon  exercise of this Warrant  shall be  adjusted,  effective at such
time, to a number determined by multiplying the number of shares of Common Stock
subject to purchase  immediately  before such Common Stock  Reorganization  by a
fraction, the numerator of which shall be the number of shares outstanding after
giving effect to such Common Stock  Reorganization  and the denominator of which
shall be the number of shares of Common  Stock  outstanding  immediately  before
such Common Stock Reorganization.

                  4.3 Common Stock Distribution.  (a) If the Company shall after
the date of issuance of this Warrant issue or otherwise  sell or distribute  any
shares of Common Stock, otherwise than pursuant to a Common Stock Reorganization
(any such event,  including any event described in paragraphs (b) and (c) below,
being  herein  called a  "Common  Stock  Distribution"),  if such  Common  Stock
Distribution  shall be for a  consideration  per share less than the Fair Market
Value per share of  outstanding  Common Stock of the Company on the date of such
Common  Stock  Distribution,  or on the first date of the  announcement  of such
Common Stock Distribution  (whichever is less), then, effective upon such Common
Stock  Distribution,  the  number of shares of  Common  Stock  purchasable  upon
exercise of this Warrant shall be adjusted by  multiplying  the number of shares
of Common Stock subject to purchase upon exercise of this Warrant by a fraction,
the  numerator  of which  shall be the total  number  of shares of Common  Stock
outstanding  (and issuable upon exercise or conversion of  outstanding  options,
warrants  and  convertible  securities)  immediately  prior to such Common Stock
Distribution  plus the number of shares of Common  Stock issued (or deemed to be
issued  pursuant  to  paragraphs  (b)  and  (c)  below)  in  such  Common  Stock

                                       7
<PAGE>

Distribution and the denominator of which shall be an amount equal to the sum of
(A) the number of shares of Common Stock outstanding (and issuable upon exercise
or conversion  of  outstanding  options,  warrants and  convertible  securities)
immediately  prior to the  Common  Stock  Distribution,  plus (B) the  number of
shares of Common Stock which the aggregate  consideration,  if any,  received by
the Company  (determined as provided  below) for such Common Stock  Distribution
would buy at the Fair Market Value thereof,  as of the date immediately prior to
such Common Stock  Distribution or as of the date immediately  prior to the date
of  announcement of such Common Stock  Distribution  (whichever is less). In the
event of any such  adjustment,  the  Exercise  Price for each  Warrant  shall be
adjusted to a number determined by dividing the Exercise Price immediately prior
to such Common  Stock  Distribution  by the  fraction  used for  purposes of the
aforementioned adjustment.

                  The provisions of this  paragraph (a),  including by operation
of paragraph (b) or (c) below,  shall not operate to increase the Exercise Price
or to reduce  the number of shares of Common  Stock  subject  to  purchase  upon
exercise of this Warrant.

                  (b) If the  Company  shall  after the date of issuance of this
Warrant  issue,  sell,  distribute  or  otherwise  grant in any manner  (whether
directly or by assumption in a merger or otherwise)  any rights to subscribe for
or to purchase,  or any warrants or options for the purchase of, Common Stock or
any stock or securities  convertible into or exchangeable for Common Stock (such
rights,  warrants or options being herein called  "Options" and such convertible
or   exchangeable   stock  or  securities   being  herein  called   "Convertible
Securities"),  whether or not such  Options or the rights to convert or exchange
any such Convertible Securities are immediately  exercisable,  and the price per
share for which  Common  Stock is issuable  upon the exercise of such Options or
upon  conversion  or  exchange of such  Convertible  Securities  (determined  by
dividing (i) the aggregate amount, if any, received or receivable by the Company
as consideration  for the granting of such Options,  plus the minimum  aggregate
amount of additional  consideration  payable to the Company upon the exercise of
all  such  Options,  plus,  in  the  case  of  Options  to  acquire  Convertible
Securities,  the minimum aggregate amount of additional  consideration,  if any,
payable  upon the  issue  or sale of such  Convertible  Securities  and upon the
conversion or exchange  thereof,  by (ii) the total maximum  number of shares of
Common Stock  issuable upon the exercise of such Options or upon the  conversion
or exchange of all such  Convertible  Securities  issuable  upon the exercise of
such Options)  shall be less than the Fair Market Value per share of outstanding
Common Stock of the Company on the date of granting  such Options or on the date
of announcement  thereof (whichever is less), then for purposes of paragraph (a)
above,  the total  maximum  number of shares of Common Stock  issuable  upon the
exercise of such  Options or upon  conversion  or exchange of the total  maximum
amount of such Convertible Securities issuable upon the exercise of such Options
shall be deemed to have been issued as of the date of  granting of such  Options
and thereafter shall be deemed to be outstanding and the Company shall be deemed
to have received as consideration  such price per share therefor,  determined as
provided  above.  Except as  otherwise  provided  in  paragraph  (d)  below,  no
additional  adjustment of the number of shares of Common Stock  purchasable upon
the  exercise of this  Warrant or of the  Exercise  Price shall be made upon the
actual  exercise  of  such  Options  or  upon  conversion  or  exchange  of such
Convertible Securities.

                                       8
<PAGE>

                  (c) If the  Company  shall  after the date of issuance of this
Warrant issue,  sell or otherwise  distribute or grant  (whether  directly or by
assumption in a merger or otherwise) any Convertible Securities,  whether or not
the rights to exchange or convert  thereunder are immediately  exercisable,  and
the price per share for which Common Stock is issuable  upon such  conversion or
exchange (determined by dividing (i) the aggregate amount received or receivable
by the Company as  consideration  for the issue,  sale or  distribution  of such
Convertible  Securities,   plus  the  minimum  aggregate  amount  of  additional
consideration,  if any,  payable to the Company upon the  conversion or exchange
thereof,  by (ii) the total  maximum  number of shares of Common Stock  issuable
upon the  conversion or exchange of all such  Convertible  Securities)  shall be
less than the Fair Market  Value per share of  outstanding  Common  Stock of the
Company  on the  date of such  issue,  sale or  distribution  or on the  date of
announcement  thereof  (whichever is less).  then, for purposes of paragraph (a)
above,  the  total  maximum  number of shares  of  Common  Stock  issuable  upon
conversion  or exchange of all such  Convertible  Securities  shall be deemed to
have  been  issued as of the date of the  issue,  sale or  distribution  of such
Convertible  Securities and thereafter shall be deemed to be outstanding and the
Company shall be deemed to have received as  consideration  such price per share
therefor,  determined  as  provided  above.  Except  as  otherwise  provided  in
paragraph (d) below, no additional  adjustment of the number of shares of Common
Stock  purchasable  upon exercise of this Warrant or of the Exercise Price shall
be made upon the actual conversion or exchange of such Convertible Securities.

                  (d) If the purchase price provided for in any Option  referred
to in paragraph (b) above,  the additional  consideration,  if any, payable upon
the  conversion  or  exchange  of  any  Convertible  Securities  referred  to in
paragraph  (b) or (c)  above,  or the rate at which any  Convertible  Securities
referred to in paragraph (b) or (c) above are  convertible  into or exchangeable
for Common  Stock  shall  change at any time  (other  than under or by reason of
provisions  designed  to protect  against,  and having the effect of  protecting
against,  dilution upon an event which results in a related adjustment  pursuant
to this  Article  IV),  the number of shares of Common  Stock  purchasable  upon
exercise of this Warrant and the Exercise  Price then in effect shall  forthwith
be readjusted (effective only with respect to any exercise of this Warrant after
such  readjustment)  to the number of shares of Common  Stock  purchasable  upon
exercise of this  Warrant and the  Exercise  Price which would then be in effect
had the  adjustment  made upon the issue,  sale,  distribution  or grant of such
Options or  Convertible  Securities  been made based upon such changed  purchase
price,  additional  consideration  or  conversion  rate,  as the  case  may  be;
provided,  however, that such readjustment shall give effect to such change only
with  respect  to  such  Options  and  Convertible  Securities  as  then  remain
outstanding.  If, at any time  after any  adjustment  of the number of shares of
Common Stock  purchasable  upon  exercise of each Warrant or the Exercise  Price
shall have been made pursuant to this Article IV on the basis of the issuance of
any Option or Convertible  Securities or after any new adjustments of the number
of shares of Common  Stock  purchasable  upon  exercise  of each  Warrant or the
Exercise  Price shall have been made  pursuant to this  paragraph,  the right of
conversion,  exercise or exchange in such Option or Convertible Securities shall
expire or  terminate,  and the right of  conversion,  exercise  or  exchange  in
respect of a portion of such  Option or  Convertible  Securities  shall not have
been  exercised,  such  previous  adjustment  shall be rescinded  and  annulled.
Thereupon,  a  recomputation  shall  be made of the  effect  of such  Option  or
Convertible  Securities  on the basis of treating the number of shares of Common
Stock, if any,  theretofore actually issued or issuable pursuant to the previous

                                       9
<PAGE>

exercise of such right of conversion, exercise or exchange as having been issued
on the  date or dates  of such  conversion,  exercise  or  exchange  and for the
consideration  actually received and receivable therefor,  and treating any such
Option or Convertible  Securities  which then remain  outstanding as having been
granted  or  issued  immediately  after  the time of any such  issuance  for the
consideration per share for which shares of Common Stock are issuable under such
Option or  Convertible  Securities;  and, if and to the extent called for by the
foregoing provisions of this Section on the basis aforesaid, a new adjustment of
the number of shares of Common Stock  purchasable  upon exercise of each Warrant
and the  Exercise  Price shall be made,  which new  adjustment  shall  supersede
(effective  only  with  respect  to any  exercise  of this  Warrant  after  such
readjustment) the previous adjustment so rescinded and annulled.

                  (e) If the  Company  shall  after the date of issuance of this
Warrant pay a dividend or make any other  distribution upon any capital stock of
the Company payable in Common Stock,  Options or Convertible  Securities,  then,
for purposes of paragraph (a) above,  such Common Stock,  Options or Convertible
Securities,  as the case may be,  shall be deemed to have  been  issued  without
consideration.

                  (f) If any  shares of Common  Stock,  Options  or  Convertible
Securities  shall be issued,  sold or distributed  for cash,  the  consideration
received therefor shall be deemed to be the gross amount received by the Company
(with no deduction  for any  underwriting  commissions  or  concessions  paid or
allowed by the Company in connection therewith).  It any shares of Common Stock,
Options or Convertible  Securities  shall be issued,  sold or distributed  for a
consideration  other than cash, the amount of the consideration  other than cash
received  by the  Company  shall be deemed to be the fair  market  value of such
consideration  as  determined  in good  faith by the Board of  Directors  of the
Company, (with no deduction for any underwriting commissions or concessions paid
or allowed  by the  Company in  connection  therewith).  If any shares of Common
Stock Options or Convertible  Securities  shall be issued in connection with any
merger  in which  the  Company  is the  surviving  corporation,  the  amount  of
consideration  therefor  shall be  deemed  to be the Fair  Market  Value of such
portion of the assets and business of the  nonsurviving  corporation as shall be
attributable  to such Common Stock,  Options or Convertible  Securities,  as the
case may be. If any  Options  shall be issued in  connection  with the issue and
sale of other  securities  of the  Company,  together  comprising  one  integral
transaction in which no specific  consideration  is allocated to such Options by
the  parties  thereto,  such  Options  shall be deemed to have been  issued  for
consideration to be determined pursuant to the Appraisal Procedure.

                  (g) If the  Company  shall take a record of the holders of the
Common  Stock for the purpose of  entitling  then to receive a dividend or other
distribution  payable in Common Stock,  Options or Convertible  Securities or to
subscribe for or purchase Common Stock, Options or Convertible Securities,  then
such record date shall be deemed to be the date of the issue, sale, distribution
or grant of the shares of Common  Stock  deemed to have been issued or sold upon
the declaration of such dividend or the making of such other distribution or the
date of the granting of such right of subscription or purchase,  as the case may
be.

                  (h) For  purposes of  determining  whether any  adjustment  is
required  pursuant to this Article IV any security of the Company  having rights
substantially equivalent to the Common Stock as to dividends or upon liquidation
dissolution  or winding up of the Company  shall be treated as if such  security
were Common Stock.

                  4.4 Dividends. If the Company shall after the date of issuance
of this  Warrant  issue or  distribute  to all or  substantially  all holders of
shares of Common Stock evidences of  indebtedness,  any other  securities of the
Company or any property,  assets or cash,  and if such issuance or  distribution
does not constitute a Common Stock Reorganization or a Common Stock Distribution
(any  such   nonexcluded   event  being  herein  called  a   "Dividend"),   then
simultaneously  with the payment of such  Dividend,  the Company will pay to the
Holder of this  Warrant an amount of property  (including,  without  limitation,
cash) and/or  securities  (including,  without  limitation,  securities of other
companies)  as would have been  received  by such Holder had it  exercised  this
Warrant  and  received  all of the  shares of  Common  Stock  issuable  upon the
exercise  of this  Warrant  immediately  prior  to the  record  date  (or  other
applicable  date) used for determining  stockholders of the Company  entitled to
receive such  Dividend.  No  adjustment in the shares of Common Stock subject to
purchase  upon the exercise of this  Warrant or in the  Exercise  Price shall be
made for any issuance or  distribution  to which the  provisions of this Section
apply.

                  4.5 Capital  Reorganization.  If after the date of issuance of
this Warrant there shall be any  consolidation or merger to which the Company is
a party,  other  than a  consolidation  or a merger  in which the  Company  is a
continuing  corporation and which does not result in any reclassification of, or
change (other than a Common Stock  Reorganization or a change in par value), in,
outstanding shares of Common Stock, or any sale or conveyance of the property of
the Company as an entirety or substantially as an entirety (any such event being
called a "Capital  Reorganization"),  then, effective upon the effective date of
such Capital  Reorganization,  the Holder shall have the right to purchase, upon
exercise  of this  Warrant,  the kind and  amount  of  shares of stock and other
securities  and property  (including  cash) which the Holder would have owned or
have been entitled to receive after such Capital  Reorganization if this Warrant
had been exercised  immediately prior to such Capital  Reorganization,  assuming
such  holder (i) is not a person  with which the  Company  consolidated  or into
which the Company  merged or which merged into the Company or to which such sale
or  conveyance  was  made,  as the case  may be  ("constituent  person"),  or an
Affiliate  of a  constituent  person and (ii) failed to  exercise  his rights of
election, if any, as to the kind or amount of securities, cash or other property
receivable upon such Capital Reorganization (provided that if the kind or amount
of   securities,   cash  or  other   property   receivable   upon  such  Capital
Reorganization  is not the same for each share of Common Stock held  immediately
prior  to  such  consolidation,  merger,  sale or  conveyance  by  other  than a
constituent  person or an Affiliate  thereof and in respect of which such rights
of election shall not have been exercised  ("non-electing  share"), then for the
purposes  of this  Section  the kind and  amount  of  shares  of stock and other
securities  or other  property  (including  cash)  receivable  upon such Capital
Reorganization shall be deemed to be the kind and amount so receivable per share
by a plurality of the non-electing  shares).  The provisions of this Section 4.5
shall similarly apply to successive  Capital  Reorganizations.  Without limiting
the  generality  of the first  sentence of this  Section 4.5, the effect of such

                                       11
<PAGE>

sentence  in the  context of a merger  ("Formation  Merger")  of the  Company in
connection with the formation of a holding company ("Holding Company"), in which
merger the holders of Common Stock receive  solely shares of common stock of the
Holding  Company,  and the number of fully diluted shares of outstanding  common
stock of the Holding Company immediately following the Formation Merger is equal
to the number of fully diluted shares of outstanding Common Stock of the Company
immediately  prior  to the  Merger,  shall be that  (i)  this  Warrant  shall be
exercisable  for the  number of shares of common  stock of the  Holding  Company
which the  Holder  would  have  owned or have been  entitled  to receive if this
Warrant had been exercised  immediately prior to such Formation Merger, and (ii)
the  provisions  of  Article  III,  this  Article  IV,  and  Section  6.10 shall
thereafter apply to the Holding Company,  such that references to the Company in
such  Articles and such Section  shall be deemed to be references to the Holding
Company,  and references to the Common Stock shall be deemed to be references to
the common stock of the Holding Company.

                  4.6 Adjustment  Rules.  (a) Any  adjustments  pursuant to this
Article IV shall be made successively whenever an event referred to herein shall
occur.

                  (b) If the Company  shall set a record date to  determine  the
holders of shares of Common Stock for purposes of a Common Stock Reorganization,
Common Stock Distribution, Dividend or Capital Reorganization, and shall legally
abandon such action prior to effecting such action,  then no adjustment shall be
made pursuant to this Article IV in respect of such action.

                  (c) No  adjustment  in the amount of shares  purchasable  upon
exercise of this Warrant or in the Exercise Price shall be made pursuant to this
Article IV unless such adjustment increases or decreases such amount or price by
one percent or more, but any such lesser adjustment shall be carried forward and
shall be made at the time and together with the next subsequent adjustment which
together  with any  adjustments  so carried  forward  shall serve to adjust such
amount or price by one percent or more.

                  (d) No  adjustment  in   the  Exercise  Price  shall  be  made
hereunder if such adjustment  would reduce the exercise price to an amount below
par value of the Common  Stock,  which par value  shall  initially  be $0.01 per
share of Common Stock.

                  (e) Notwithstanding   anything  in   this  Agreement  to   the
contrary,  no adjustment  shall be made pursuant to this Article IV or otherwise
(including  without limitation in the amount of shares purchasable upon exercise
of this  Warrant or in the  Exercise  Price) in respect of or as a result of (i)
the issuance (or deemed  issuance)  or  repurchase  of shares of Common Stock in
connection  with the  exercise of the  Warrants or (ii) the  issuance (or deemed
issuance),  sale,  grant or distribution  of shares of Common Stock,  Options or
Convertible  Securities  in an  underwritten  public  offering,  or a Rule  144A
offering,  managed by a nationally or regionally  recognized  investment banking
firm,  (iii) the issuance (or deemed  issuance),  sale,  grant,  distribution or
repurchase of shares of Common Stock, Options or Convertible Securities,  or any
other transaction,  if any such issuance, sale, grant, distribution,  repurchase
or other  transaction  is between  the  Company  and any person or entity not an
Affiliate of the Company or is part of or made pursuant to a transaction between
the Company and any person or entity not an Affiliate of the Company  (including

                                       12
<PAGE>

without limitation any issuance (or deemed issuance),  sale, grant, distribution
or repurchase of shares of Common Stock,  Options, or Convertible  Securities as
part of or  pursuant  to a merger  between  the  Company  and an  entity  not an
Affiliate  of the  Company or the  purchase of  substantially  all assets by the
Company of an entity not an  Affiliate  of the  Company),  (iv) the issuance (or
deemed issuance),  sale,  grant,  distribution or repurchase of shares of Common
Stock, Options or Convertible Securities to or from an Affiliate of the Company,
or any other transaction with an Affiliate of the Company, if any such issuance,
sale, distribution,  repurchase or other transaction is approved by the majority
of directors not affiliated with such Affiliate,  or (v) the issuance (or deemed
issuance),  sale,  grant,  distribution or repurchase of shares of Common Stock,
Options or Convertible  Securities to or from an employee of the Company, or any
other transaction with an employee of the Company, (including without limitation
the  granting  of  stock  options,   restricted   stock  or  other   stock-based
compensation  to an  employee  of the  Company),  if any  such  issuance,  sale,
distribution,  repurchase  or other  transaction  is approved by the majority of
non-employee  directors  of the  Company,  or by the  majority  of  non-employee
directors on a committee of directors  consisting  of at least two  non-employee
directors of the Company.  The issuance of Common Stock to KLT Telecom Inc. upon
conversion  of preferred  stock owned by KLT Telecom Inc.  pursuant to the Stock
Purchase  Agreement  dated  December 31, 1996 by and between the Company and KLT
Telecom Inc. is included  within  category (iii) in the previous  sentence,  and
following  the  Formation  Merger,  in which  such  preferred  stock held by KLT
Telecom is exchanged  for preferred  stock of the Holding  Company with the same
rights of conversion,  the issuance of common stock of the Holding  Company upon
conversion of such  preferred  stock of the Holding  Company is included  within
category (iii) in the previous sentence.  Notwithstanding  the first sentence of
this  Section  4.6(e),  this  Section  4.6(e)  shall not  operate  to prevent an
adjustment  pursuant to the other  provisions  of this Article IV for (i) Common
Stock  Reorganizations,  dividends  of  Common  Stock,  Options  or  Convertible
Securities,  or Capital  Reorganizations,  affecting all holders of Common Stock
similarly  situated or (ii) the  issuance  (or deemed  issuance),  sale,  grant,
distribution  or repurchase of shares of Common  Stock,  Options or  Convertible
Securities to or from an Affiliate of the Company, or any other transaction with
an Affiliate of the Company, if such issuance, sale, distribution, repurchase or
other  transaction  is  voted  for  by the  directors  affiliated  with  another
Affiliate of the Company with the agreement or understanding  that the directors
affiliated  with such Affiliate  shall in exchange vote in favor of the issuance
(or deemed  issuance),  sale,  grant,  distribution  or  repurchase of shares of
Common Stock, Options or Convertible Securities to or from such other Affiliate,
or any other transaction with such other Affiliate.

                  4.7 Proceedings Prior to Any Action Requiring Adjustment. As a
condition  precedent  to the  taking  of  any  action  which  would  require  an
adjustment  pursuant to this Article IV, the Company shall take any action which
may be necessary,  including obtaining  regulatory  approvals or exemptions,  in
order that the Company may  thereafter  validly and legally  issue as fully paid
and  nonassessable  all shares of Common Stock which the holders of Warrants are
entitled to receive upon exercise thereof.

appraiser within 15 days after the Appraisal  Procedure is invoked. If within 30
days after  appointment of the two appraisers  they are unable to agree upon the
amount in question, a third independent appraiser shall be chosen within 10 days
thereafter by the mutual  consent of such first two appraisers or, if such first
two appraisers  fail to agree upon the  appointment of a third  appraiser,  such
appointment  shall  be  made by the  American  Arbitration  Association,  or any
organization successor thereto, from a panel of arbitrators having experience in

of this Warrant as is being sold by KLT and  Weinstein  on a combined  basis (as
measured at the time of the  transaction,  or the first of any series of related
transactions),  (ii)  at the  same  price  and  (iii)  on  the  same  terms  and
conditions,  as KLT and  Weinstein  have agreed to sell their Common  Stock.  If
either  KLT,  on the one  hand,  or  Weinstein,  on the  other,  agree to sell a
significant   portion  of  its  or  his  Common   Stock  to  Weinstein  or  KLT,
respectively, then upon the request of the Holder, KLT or Weinstein, as the case
may be, shall afford to the Holder the  opportunity to sell to Weinstein or KLT,
respectively  (i) the same  percentage of Common Stock issuable upon exercise of
this  Warrant as is being sold by KLT or Weinstein  on an  individual  basis (as
measured at the time of the  transaction,  or the first of any series of related
transactions),  (ii)  at the  same  price  and  (iii)  on  the  same  terms  and
conditions,  as KLT or Weinstein,  as the case may be, have agreed to sell their
Common Stock. The phrase "substantial portion", as used in the first sentence of
this  Section  6.10(a),  shall  mean  any  sale of 55% or  more of the  combined
holdings of KLT and Weinstein,  and the phrase "significant  portion" as used in
the second sentence of this Section 6.10(a),  shall mean any sale of 10% or more
of KLT's or Weinstein's individual holding, as the case may be.

                  (b) If both KLT Telecom Inc.  ("KLT") and Richard D. Weinstein
("Weinstein")  agree to sell a  substantial  portion of their  Common Stock to a
third party in any one transaction or series of related transactions (other than
a public  offering),  then KLT and Weinstein shall have the right to require the
Holder to sell to such  third  party  (i) the same  percentage  of Common  Stock
issuable  upon exercise of this Warrant as is being sold by KLT and Weinstein on
a combined  basis (as measured at the time of the  transaction,  or the first of
any  series of  related  transactions),  (ii) at the same price and (iii) on the
same terms and conditions, as KLT and Weinstein have agreed to sell their Common
Stock. If either KLT, on the one hand, or Weinstein, on the other, agree to sell
a  significant  portion  of  its  or his  Common  Stock  to  Weinstein  or  KLT,
respectively, then KLT or Weinstein, as the case may be, shall have the right to
require  the  Holder  to sell to  Weinstein  or KLT,  respectively  (i) the same
percentage  of Common Stock  issuable  upon exercise of this Warrant as is being
sold by KLT or Weinstein on an individual  basis (as measured at the time of the
transaction,  or the first of any series of related  transactions),  (ii) at the
same price and (iii) on the same terms and conditions,  as KLT or Weinstein,  as
the case may be, have agreed to sell their Common Stock. The phrase "substantial
portion", as used in the first sentence of this Section 6.10(b),  shall mean any
sale of 55% or more  of the  combined  holdings  of KLT and  Weinstein,  and the
phrase  "significant  portion" as used in the second  sentence  of this  Section
6.10(b),  shall mean any sale of 10% or more of KLT's or Weinstein's  individual
holding, as the case may be.

                   (c) Prior to making any sale  covered  by Section  6.10(a) or
6.10(b) ("Stock Sale"), KLT and Richard D. Weinstein shall provide the holder of
this  Warrant  with written  notice (the "Sale  Notice") in the manner  provided
herein.  If KLT and/or Weinstein are exercising their rights pursuant to Section
6.10(b),  or if the consideration in a Stock Sale is cash, the Sale Notice shall
be given at least ten days prior to the proposed date of such sale. In all other
situations, the notice shall be given fifteen days prior to the proposed date of
such sale.  The Sale  Notice will  indicate  whether  KLT and/or  Weinstein  are
exercising  their  rights  pursuant to Section  6.10(b),  and will  identify the
proposed  purchaser,  the  percentage  of Common Stock to be sold,  the proposed
amount and form of  consideration to be paid per share, the terms and conditions

                                       19

of payment and the  proposed  date of such sale  ("Stock Sale Date") and, if KLT
and Weinstein are not exercising  their rights pursuant to Section  6.10(b),  an
address or  facsimile  telephone  number to which the Holder must give notice of
its intention to exercise its rights  pursuant to Section  6.10(a).  To exercise
its rights under Section 6.10(a), the Holder must give written notice to KLT and
Weinstein at such address or telephone  facsimile  telephone number at least one
day prior to Closing.

                  (d) On the Stock  Sale  Date,  if KLT  and/or  Weinstein  have
exercised  their  rights  pursuant  to  Section  6.10(b),  or if the  holder has
exercised its rights under Section 6.10(a),  then the holder shall exercise this
Warrant as specified in Section 1.1 of this Warrant prior to the consummation of
the Stock  Sale,  and shall  deliver the  certificates  for the shares of Common
Stock  issuable upon  exercise of this Warrant,  together with such stock powers
and other appropriate  instruments of assignment duly executed, to the purchaser
in the manner and at the address indicated in the Sale Notice,  against delivery
of the purchase price therefor.

                  (e) The rights and  obligations  under this Section 6.10 shall
not extend to any  successor to part or all of the interest of Weinstein or KLT,
unless in a writing delivered to the Holder such successor agrees to be bound by
this Section  6.10, in which event such  successor  shall be bound by, and shall
have the rights set forth in, this  Section 6.10 as if such  successor  had been
named  in this  Section  6.10  (including  without  limitation  in this  Section
6.10(e)) in lieu of Weinstein or KLT or, if not all of the stock of Weinstein or
KLT is sold,  in addition to  Weinstein  and KLT. If  Weinstein  or KLT, but not
both,  sells  all of his or its  Common  Stock,  as the  case  may  be,  and the
successor  does not  agree to be bound by this  Section  6.10,  the  rights  and
obligations  of this  Section  6.10  shall  continue  to apply to  whichever  of
Weinstein or KLT did not sell,  as if the selling  party had never been named in
this Section 6.10.  If Weinstein or KLT, or both,  sells less than all of his or
its Common  Stock,  as the case may be, and any  successor  does not agree to be
bound by this  Section  6.10,  the rights and  obligations  of this Section 6.10
shall  continue to apply to  Weinstein  or KLT with  respect to their  remaining
holdings.

                  (f) This Section 6.10 shall  terminate upon the later to occur
of (i) the date of an initial public offering of the Common Stock,  and (ii) the
time at which the  Holder  may sell  free of  restriction  pursuant  to Rule 144
promulgated under the Securities Act of 1933, as amended.
