                      40,000 COMMON STOCK PURCHASE WARRANTS

                                                             Teaneck, New Jersey
Warrant Certificate No. AA-4                                     January 8, 2000

          THIS IS TO  CERTIFY  THAT,  for  value  received,  Arel AMG,  Inc.,  a
Delaware  corporation or registered assigns (the  "Warrantholder")  permitted by
the terms of this Warrant Certificate,  is the registered owner of the number of
Common Stock Purchase Warrants (each, a "Warrant") set forth above, each Warrant
entitling   the  owner  thereof  to  purchase  from  Vizacom  Inc.,  a  Delaware
Corporation  (the  "Company"),  at any time  commencing  on or after the date on
which the Company or an affiliate of the Company  consummates three acquisitions
of  companies  located in Europe that was  introduced  to the Company by Schlomo
Lazar or the Warrantholder (the  "Commencement  Time") on or prior to 5:00 P.M.,
New York  City  time,  on  January  7, 2003 (the  "Expiration  Time"),  one duly
authorized, validly issued, fully paid and nonassessable share (each, a "Warrant
Share") of the common stock, par value $.001 per share ("Common Stock"),  of the
Company,  at a purchase  price of $3.00 per share (the  "Purchase  Price"),  all
subject to the terms and  conditions  contained  herein.  The number of Warrants
evidenced by this  Warrant  Certificate  (and the number and kind of  securities
which may be purchased upon exercise  hereof) set forth above,  and the Purchase
Price per share set forth above, are as of the date hereof.  As provided herein,
the Purchase Price and the number of shares of Common Stock or other  securities
which may be  purchased  upon the  exercise of the  Warrants  evidenced  by this
Warrant  Certificate  are,  upon the  happening  of certain  events,  subject to
modification and adjustment.

<PAGE>
          This  Warrant  Certificate,  together with  any warrant certificate(s)
issued in replacement or substitution hereof (as provided for herein) evidencing
all  or  part  of  the  Warrants  evidenced  hereby, are sometimes  collectively
referred to herein as the "Warrant Certificates."

          The rights  of the registered holder of this Warrant Certificate shall
be subject to the following further terms and conditions:

1.   EXERCISE OF WARRANTS.

          (a)   The Warrants may be exercised,  in whole or in part, on or prior
to the Expiration  Time  by  surrendering  this  Warrant  Certificate,  with the
purchase form provided for herein duly executed by the Warrantholder or  by  the
Warrantholder's duly  authorized  attorney-in-fact, at the principal  office  of
the  Company, presently  located at Glenpointe  Centre  East,  300 Frank W. Burr
Boulevard - 7th Floor,  Teaneck,  New Jersey  07666, or at such other  office or
agency  in  the  United  States  as the  Company  may  designate  by  notice  in
writing  to  the  Warrantholder  (in  either  event,  the  "Company   Offices"),
accompanied by payment in full, either in the form of cash, bank cashier's check
or certified  check payable to the  order  of the Company, of the Exercise Price
payable in respect of the Warrants being  exercised.   If  fewer than all of the
Warrants are exercised,  the Company shall,  upon  each exercise  prior  to  the
Expiration  Time,  execute  and  deliver  to  the  Warrantholder  a  new Warrant
Certificate  (dated  as  of  the  date hereof)  evidencing  the  balance  of the
Warrants that remain exercisable.

          (b)   On  the  date  of  exercise  of  the Warrants, the Warrantholder
exercising same shall be deemed to  have  become the holder of  record  for  all
purposes of the Warrant Shares to which the exercise relates.

          (c) As soon as practicable, but not in excess of ten  days, after  the
exercise of all or part of the Warrants  evidenced by this Warrant  Certificate,
the Company, at its expense (including the payment by it of any applicable issue
taxes),  will  cause  to  be  issued  in  the  name  of  and  delivered  to  the
Warrantholder  a  certificate  or  certificates  evidencing  the  number of duly
authorized, validly issued, fully paid and nonassessable Warrant Shares to which
the Warrantholder shall be entitled upon such exercise.

          (d) No certificates for fractional Warrant Shares shall be issued upon
the exercise of any of the  Warrants  but,  in  lieu thereof, the Company shall,
upon exercise  of all the Warrants, round up any fractional Warrant Share to the
nearest whole share of Common Stock.

2.   ISSUANCE OF COMMON STOCK; RESERVATION OF SHARES.

          (a) The Company covenants and agrees that all Warrant Shares which may
be issued upon the exercise of all or part of the Warrants  will,  upon issuance
in  accordance with the  terms  hereof,   be  validly  issued,  fully  paid  and
nonassessable  and free from all taxes,  liens and charges  with  respect to the
issue thereof.

                                      -2-
<PAGE>

          (b)  The Company  further  covenants and  agrees that if any shares of
Common Stock to be reserved for the purpose of  the  issuance of Warrant  Shares
upon the exercise of Warrants require  registration  with,  or  approval of, any
governmental authority under any  federal or state law  before  such  shares may
be validly issued or delivered upon  exercise,  then the Company  will  promptly
use its best efforts to effect such registration or obtain such approval, as the
case may be.

3.   ADJUSTMENTS OF EXERCISE PRICE, NUMBER AND CHARACTER OF WARRANT SHARES, AND
     NUMBER OF WARRANTS.

          The Exercise Price the number and kind of securities  purchasable upon
the exercise  of each Warrant shall be subject to  adjustment  from time to time
upon the happening of the events enumerated in this Section 3.

          (a)   STOCK  DIVIDENDS,  SUBDIVISIONS  AND  COMBINATIONS.  In case the
Company shall at any time on or before the Expiration Time:

                (i)   pay a dividend in shares of Common Stock  [or other  stock
     of the  Company]  or  make a distribution in shares of Common Stock or such
     other stock to holders of all its outstanding shares of Common Stock;

                (ii)  subdivide  or  reclassify the outstanding shares of Common
     Stock into a greater number of shares;

                (iii) combine  the  outstanding  shares  of  Common Stock into a
     smaller number of shares of Common Stock; or

                (iv)  issue  by  reclassification  of its shares of Common Stock
     other  securities  of  the  Company (including any such reclassification in
     connection  with  a  consolidation  or  merger  in which the Company is the
     continuing corporation);

then  the  number  and  kind  of Warrant  Shares  purchasable  upon  exercise of
each Warrant outstanding immediately prior thereto shall be adjusted so that the
Warrantholder  shall be  entitled  to  receive  the kind and number of shares of
Common Stock or other  securities of the Company which the  Warrantholder  would
have owned or have been  entitled to receive  after the  happening of any of the
events described above had such Warrant been exercised in full immediately prior
to the  earlier of the  happening  of such  event or any record  date in respect
thereto.  In the  event  of any  adjustment  of the  number  of  Warrant  Shares
purchasable upon the exercise of each then outstanding Warrants pursuant to this
Paragraph 3(a), the Exercise Price shall be adjusted to be the amount  resulting
from dividing the number of shares of Common Stock (including  fractional shares
of Common Stock) covered by such Warrant  immediately after such adjustment into
the total amount payable upon exercise of such Warrant in full immediately prior
to such  adjustment.  An adjustment  made pursuant to this  Paragraph 3(a) shall
become effective  immediately after the effective date of such event retroactive
to  the  record  date  for  any  such  event.  Such  adjustment  shall  be  made
successively whenever any event listed above shall occur.

                                      -3-
<PAGE>

          (b)  EXTRAORDINARY DIVIDENDS. In case the Company shall at any time on
or before the Expiration  Time fix a record  date for the  issuance  of  rights,
options,  or warrants to all holders of its outstanding  shares of Common Stock,
entitling them (for a period  expiring within 45 days after such record date) to
subscribe for or purchase shares of Common Stock (or securities exchangeable for
or convertible into shares of Common Stock) at a price per share of Common Stock
(or having an  exchange  or  conversion  price per share of Common  Stock,  with
respect to a security  exchangeable  for or  convertible  into  shares of Common
Stock)  which is lower than the current  Market  Price per share of Common Stock
(as defined in  Paragraph  3(d) below) on such record  date,  then the  Exercise
Price shall be adjusted by multiplying the Exercise Price in effect  immediately
prior to such record date by a fraction, of which (i) the numerator shall be the
number of shares of Common Stock outstanding on such record date plus the number
of shares of Common Stock which the aggregate offering price of the total number
of shares of Common Stock so to be offered (or the aggregate initial exchange or
conversion price of the exchangeable or convertible securities so to be offered)
would  purchase at such current Market Price and (ii) the  denominator  shall be
the number of shares of Common  Stock  outstanding  on such record date plus the
number of additional  shares of Common Stock to be offered for  subscription  or
purchase (or into which the  exchangeable  or  convertible  securities  so to be
offered are initially exchangeable or convertible). Such adjustment shall become
effective at the close of business on such record date;  however,  to the extent
that shares of Common Stock (or securities  exchangeable for or convertible into
shares of Common Stock) are not delivered  after the  expiration of such rights,
options,  or warrants,  the Exercise  Price shall be  readjusted  (but only with
respect to Warrants exercised after such expiration) to the Exercise Price which
would  then be in effect  had the  adjustments  made upon the  issuance  of such
rights,  options,  or warrants  been made upon the basis of delivery of only the
number of shares of Common Stock (or securities  exchangeable for or convertible
into shares of Common Stock) actually issued. In case any subscription price may
be paid in a  consideration  part or all of which  shall be in a form other than
cash,  the value of such  consideration  shall be as determined in good faith by
the Board of  Directors  of the  Company and shall be  described  in a statement
mailed to the  Warrantholder.  Shares of Common  Stock  owned by or held for the
account of the Company  shall not be deemed  outstanding  for the purpose of any
such computation.

         (c)  EXTRAORDINARY DISTRIBUTIONS. In case the Company shall at any time
after the  original  date of issuance of the Warrants  (the "Date of  Issuance")
distribute  to all  holders of its shares of Common  Stock  (including  any such
distribution  made in  connection  with a  consolidation  or merger in which the
Company is the surviving  corporation)  evidences of its  indebtedness or assets
(excluding  cash dividends and  distributions  payable out of  consolidated  net
income or earned  surplus in  accordance  with  Delaware  law and  dividends  or
distributions  payable in shares of stock  described in Paragraph 3(a) above) or
rights,   options,  or  warrants  or  exchangeable  or  convertible   securities
containing  the right to  subscribe  for or purchase  shares of Common Stock (or
securities  exchangeable for or convertible  into shares of Common Stock),  then
the Exercise Price shall be adjusted by multiplying the Exercise Price in effect
immediately  prior to the record date for such  distribution  by a fraction,  of
which (i) the  numerator  shall be the current  Market Price per share of Common
Stock (as defined in Paragraph  3(d)) on such record date,  less the fair market
value  (as  determined  by  the  Board  of  Directors  of  the  Company,   whose
determination   shall  be   conclusive,   and  described  in  a  notice  to  the
Warrantholders)  of the portion of the evidences of indebtedness or assets so to
be distributed or of such rights, options or warrants applicable to one share of
Common Stock

                                      -4-
<PAGE>

and  (ii)  the  denominator  shall  be  such  current  Market Price per share of
Common Stock.  Such adjustment  shall be made whenever any such  distribution is
made, and shall become effective on the date of distribution  retroactive to the
record date for such transaction.

          (d)  CURRENT MARKET PRICE DEFINED.  For the purpose of any computation
under Paragraphs 3(b) and/or 3(c), the current Market Price per share of  Common
Stock at  any date shall be deemed to be the average  daily Closing Price of the
shares of Common Stock for twenty consecutive trading days ending within fifteen
days before the date in question.  The term  "Closing Price"  of  the  shares of
Common Stock for a day or days shall mean (i) if the shares of Common  Stock are
listed  or  admitted  for trading on a national  securities  exchange,  the last
reported sales price regular way, or, in case no such  reported sale takes place
on such day or days,  the average  of the reported  closing bid and asked prices
regular way, in either case on  the principal  national  securities  exchange on
which the shares of the Common  Stock  are listed or admitted  for  trading,  or
(ii) if the shares of Common Stock are not  listed or  admitted  for  trading on
a national securities  exchange,  (A)  the last transaction price for the Common
Stock on The Nasdaq  Stock Market  ("Nasdaq")  or, in the case no such  reported
transaction takes  place  on  such  day  or  days,  the average of the  reported
closing bid and asked prices thereof quoted on  Nasdaq,  or (B) if the shares of
Common Stock are not quoted on Nasdaq,  the average of the closing bid and asked
prices of the Common  Stock  as  quoted  on the Over-The-Counter  Bulletin Board
maintained  by  the  National  Association  of  Securities  Dealers,  Inc. ( the
"Bulletin Board"),  or  (C)  if the  shares of  Common  Stock are not  quoted on
Nasdaq  nor on the  Bulletin Board,  the  average  of  the closing bid and asked
prices of the common  stock in the over-the-counter market, as  reported  by The
National Quotation Bureau, Inc., or an equivalent  generally  accepted reporting
service,  or (iii) if on any such trading  day  or days  the  shares  of  Common
Stock  are not  quoted by any such organization, the fair  market  value  of the
shares of  Common  Stock on such day or days,  as  determined  in good faith  by
the Board of  Directors of the Company, shall be used.

          (e) MINIMUM ADJUSTMENT.  Except as hereinafter provided, no adjustment
of the  Exercise Price hereunder shall be made if such  adjustment  results in a
change of the  Exercise  Price then in effect of less than five cents ($.05) per
share.  Any  adjustment of less than five cents ($.05) per share of any Exercise
Price  shall be carried  forward  and shall be made at the time of and  together
with any subsequent adjustment which, together with adjustment or adjustments so
carried forward,  amounts to five cents ($.05) per share or more. However,  upon
exercise  of this  Warrant  Certificate,  the Company  shall make all  necessary
adjustments (to the nearest cent) not theretofore  made to the Exercise Price up
to and  including  the  effective  date upon which this Warrant  Certificate  is
exercised.

          (f)  NOTICE OF ADJUSTMENTS.    Whenever  the  Exercise  Price shall be
adjusted  pursuant  to  this  Section 3, the Company  shall  promptly  deliver a
certificate signed  by the  President,  a  Vice  President, the  Chief Financial
Officer,  Treasurer  or an Assistant  Treasurer or the Secretary or an Assistant
Secretary of  the  Company,  setting  forth,  in  reasonable  detail,  the event
requiring the adjustment,  the amount of the  adjustment,  the  method  by which
such  adjustment was  calculated  (including  a  description  of  the  basis  on
which  the Board of Directors of the Company made any determination  hereunder),
by first class mail postage prepaid to each Warrantholder.

          (g) CAPITAL  REORGANIZATIONS  AND OTHER  RECLASSIFICATIONS. In case of
any capital  reorganization  of  the  Company, or of any reclassification of the
shares  of   Common  Stock  (other  than  a  reclassification,  subdivision   or
combination of shares  of  Common  Stock  referred  to in  Paragraph  3(a)),  or
in case of the consolidation  of the Company with, or the merger of the  Company
with,  or  merger  of  the  Company  into,  any  other corporation (other than a
reclassification of the shares of Common  Stock  referred to in  Paragraph  3(a)
or a  consolidation  or merger  which  does not result  in  any reclassification
or  change  of  the outstanding  shares of Common Stock)  or  of the sale of the
properties and assets of the Company as, or substantially as, an entirety to any
other   corporation   or  entity,   each  Warrant  shall,  after  such   capital
reorganization,  reclassification  of  shares  of  Common Stock,  consolidation,
merger, or sale, be exercisable, upon the terms and conditions specified in this
Warrant  Certificate,  for  the  kind,  amount  and  number  of shares  or other
securities,  assets, or cash to which a holder of the number of shares of Common
Stock  purchasable (at the time of such capital reorganization, reclassification
of   shares   of   Common   Stock, consolidation,  merger or sale) upon exercise
of  such  Warrant  would   have  been  entitled  to  receive  upon  such capital
reorganization,  reclassification  of  shares  of Common  Stock,  consolidation,
merger, or sale;  and in any such  case,  if necessary, the provisions set forth
in  this  Section  3  with respect to the rights and interests thereafter of the
Warrantholder shall be appropriately adjusted so as to be applicable,  as nearly
equivalent  as  possible,  to  any shares or other securities,  assets,  or cash
thereafter  deliverable on the  exercise  of the Warrants. The Company shall not
effect  any   such   consolidation,   merger,  or  sale,  unless  prior  to   or
simultaneously  with  the  consummation  thereof  the  successor corporation  or
entity  (if  other  than  the  Company)   resulting  from  such consolidation or
merger or the corporation or entity  purchasing such assets or other appropriate
corporation  or  entity  shall  assume, by written instrument, the obligation to
deliver to the Warrantholder such shares,  securities,  assets,  or  cash as, in
accordance  with  the  foregoing  provisions,  such  holders  may be entitled to
purchase and the other  obligations  hereunder.  The  subdivision or combination
of  shares  of  Common  Stock  at any time  outstanding into a greater or lesser
number of shares  shall  not be deemed  to be a  reclassification  of the shares
of Common Stock for purposes of this Paragraph 3(e).

          (h)  ADJUSTMENTS TO OTHER  SECURITIES.  In the event that at any time,
as a result of an adjustment made pursuant to this Section 3, the  Warrantholder
shall become entitled to purchase any shares or  securities of the Company other
than the  shares of Common Stock, thereafter the number of such other  shares or
securities so  purchasable  upon exercise of each Warrant and the exercise price
for such shares or securities  shall be subject to adjustment  from time to time
in a manner and on terms as nearly equivalent as possible to the provisions with
respect to the shares of Common Stock  contained in Paragraphs 3(a) through (e),
inclusive.

          (i)  DEFERRAL   OF   ISSUANCE   OF   ADDITIONAL   SHARES   IN  CERTAIN
CIRCUMSTANCES.  In  any case in  which  this  Section  3 shall  require  that an
adjustment  in the  Exercise  Price  be made effective as of a record date for a
specified  event, the Company may elect to defer  until the  occurrence  of such
event  issuing to the Warrantholder  exercised after such record date the shares
of Common Stock,  if any,  issuable  upon  such  exercise  over  and  above  the
Warrant  Shares,  if any,  issuable upon such  exercise  on  the  basis  of  the
Exercise  Price in effect prior  to such adjustment; provided, however, that the
Company shall deliver as soon as  practicable to such holder a due bill or other
appropriate  instrument  provided by the Company  evidencing such holder's right
to  receive  such  additional  shares of Common Stock upon the occurrence of the
event requiring such adjustment.

     4.   DEFINITION OF COMMON STOCK.

          The  Common  Stock issuable upon exercise of the Warrants shall be the
Common  Stock as constituted on the date hereof except as otherwise  provided in
Section 3.

5.   REPLACEMENT OF SECURITIES.

          If  this  Warrant  Certificate  shall  be  lost, stolen,  mutilated or
destroyed, the Company shall, on such terms as to  indemnity or otherwise as the
Company may in its discretion reasonably impose, issue a new certificate of like
tenor or date  representing  in  the  aggregate  the right to subscribe for  and
purchase the number of  shares of Common  Stock  which may be subscribed for and
purchased hereunder.  Any such new  certificate  shall  constitute  an  original
contractual obligation of the  Company,  whether  or  not  the  allegedly  lost,
stolen,  mutilated  or  destroyed  Warrant  Certificate  shall  be  at  any time
enforceable by anyone.

6.   REGISTRATION.

          This  Warrant  Certificate,  as well as all other warrant certificates
representing  Warrants  shall be numbered and shall be  registered in a register
(the "Warrant  Register")  maintained at the Company Offices as they are issued.
The Warrant  Register shall list the name,  address and Social Security or other
Federal Identification Number, if any, of all Warrantholders.  The Company shall

such Warrants on the part of any other  person,  and shall not be liable for any
registration  of transfer of Warrants that are registered or to be registered in
the name of a  fiduciary  or the  nominee of a  fiduciary  unless  made with the
actual  knowledge that a fiduciary or nominee is committing a breach of trust in
requesting such  registration of transfer,  or with such knowledge of such facts
that its participation therein amounts to bad faith.

10.  REGISTRATION RIGHTS.

          (a) Defined  Terms.  As  used  in  this  Section  10,  terms   defined
elsewhere herein shall have their assigned  meanings and  each of the  following
terms shall have the  following  meanings  (such  definitions  to be  applicable
to both the plural and singular of the terms defined):

                    (i)    Registerable   Securities.   The  term  "Registerable
     Securities" shall mean any of the  Warrant  Shares, including any shares of
     Common  Stock  or  other  securities  received in connection with any stock
     split,   stock   divided,   merger,   reorganization,     recapitalization,
     reclassification or other distribution  payable  or issuable upon shares of
     Common Stock.  For the purposes of this Agreement, securities will cease to
     be  Registerable  Securities  when  (A)  a registration statement under the
     Securities Act  covering such Registerable  Securities  has  been  declared
     effective and either (1) such Registerable Securities have been disposed of
     pursuant  to  such  effective  registration   statement  or  (2)  (I)  such
     Registerable  Securities  remain  covered  by  such  effective Registration
     Statement, (II) such Registerable Securities have been  withdrawn from such
     Registration Statement at  the  request  or  demand  of  the holder of such
     Registerable  Securities  or  (III)  such  registration  statement has been
     withdrawn at the request  or demand of  the  holder  of  such  Registerable
     Securities, (B) such Registerable  Securities are distributed to the public
     pursuant  to  the  Securities  Act or pursuant to  an  exemption  from  the
     registration requirements of the Securities Act, including, but not limited
     to, Rules 144 and 144A promulgated  under  the  Securities Act, or (C) such
     Registerable Securities have been otherwise transferred and the Company, in

                                      -8-

     accordance  with  applicable  law  and  regulations,  has   delivered   new
     certificates or other evidences of ownership for such securities  which are
     not subject to any stop transfer order or other restriction on transfer.

                    (ii)  Rightsholders.  The term "Rightsholders" shall include
     the Warrantholder, all successors and assigns of the Warrantholder, and all
     transferees of Registerable  Securities  where  such transfer affirmatively
     includes  the  transfer  and  assignment of the rights  of  the  transferor
     Rightsholder  under  this  Agreement  with  respect   to   the  transferred
     Registerable Securities; provided, however, the term  "Rightsholders" shall
     not include any person or entity who has sold, transferred  or assigned all
     of such person's or entity's Registerable Securities.

                    (iii)     The  words  "hereof," "herein" and "hereunder" and
     words of similar import when used in this  Section  10  shall refer to this
     Section 10 as a whole and not to any particular provision  of  this Section
     10, and subsection, paragraph, clause, schedule and exhibit references  are
     to this Section 10 unless otherwise specified.

          (b)  Demand Registration.

                    (i)   The  Company  hereby  covenants and agrees to register
     (the  "Demand  Registration"),  under  the  Securities  Act,  all  of   the
     Registerable Securities.

                    (ii)  Number of Demand Registrations; Expenses.  The holders
     of Registerable Securities  shall  be  entitled,  in  the aggregate, to one
     Demand  Registration,  the  Registration  Expenses (as defined in Paragraph
     10(e) hereof) of which, subject to the provisions of Paragraph 10(e), shall
     be borne by the Company, but the Company shall  not  be responsible for the
     payment of any underwriter's discount, commission or selling  concession in
     connection with any of the Registerable Securities.   The Company shall not
     be  deemed  to  have  effected  a Demand Registration unless and until such
     Demand Registration is declared effective.

                    (iii) Approval of Underwriter by the Company.  If the Demand
     Registration  is  to  involve  an   underwritten  offering,  the   managing
     underwriter(s)  and  each  selling  agent  selected  by those Rightsholders
     participating  in  each  such underwritten offering shall be Subject to the
     written approval of the Company,  which  approval  may  not be unreasonably
     withheld.

                    (vi)  "Initiating  Holders"  Defined.  For  purposes of this
     Agreement,  the  term "Initiating  Holders" shall  mean, on any given date,
     those Rightsholders holding Registerable Securities  which  would aggregate
     50% or more of the total Registerable Securities that would be  outstanding
     on such date.

          (c)  Piggy-Back Registration.

                                      -9-
<PAGE>

                    (i)   If,  at  any  time  on or after the date on which this
     warrant certificate has been issued and on  or prior to two years after the
     Expiration Time, the Company  proposes  to file  a  registration  statement
     under the Securities Act with respect to  an offering by the Company or any
     other party of any class of equity security  similar  to  any  Registerable
     Securities  (other  than a registration statement on Form S-4 or S-8 or any
     successor form or a  registration statement filed solely in connection with
     an exchange offer, a  business  combination  transaction  or an offering of
     securities  solely  to  the  existing  stockholders  or  employees  of  the
     Company),  then the Company, on  each  such  occasion,  shall give  written
     notice  (each,  a  "Company Piggy-Back Notice") of such  proposed filing to
     all of the Rightsholders owning  Registerable  Securities  at least 20 days
     before  the  anticipated filing date of such registration  statement,   and
     such  Company Piggy-Back Notice  also  shall  be  required to offer to such
     Rightsholders   the  opportunity  to  register  such  aggregate  number  of
     Registerable Securities as each such  Rightsholder may request.  Each  such
     Rightsholder shall have the right, exercisable for the ten days immediately
     following the  giving  of  the  Company  Piggy-Back  Notice, to request, by
     written notice (each, a "Holder Notice")  to  the  Company,  the  inclusion
     of   all  or  any   portion   of   the   Registerable  Securities  of  such
     Rightsholders  in   such   registration  statement.  The Company shall  use
     reasonable  efforts  to  cause  the  managing  underwriter(s) of a proposed
     underwritten  offering  to  permit  the   inclusion  of  the   Registerable
     Securities  which  were  the  subject   of  all  Holder  Notices  in   such
     underwritten  offering  on  the  same terms and  conditions  as any similar
     securities  of  the  Company  included  therein.   Notwithstanding anything
     to  the  contrary  contained  in  this Paragraph 10(c)(i), if the  managing
     underwriter(s)  of  such  underwritten  offering  (or,  in  the  case of an
     offering not being underwritten, the Company)  delivers  a written  opinion
     (or,  in  the  case of  the Company, a resolution of its Board of Directors
     certified  by   the  President  or  Secretary  of   the  Company)   to  the
     Rightsholders  of  Registerable  Securities  which  were the subject of all
     Holder Notices that the total amount and kind of securities which they, the
     Company and any other person Intend to include  in such offering is such as
     to  materially  and adversely affect the success of such offering, then the
     amount of securities  to be  offered for the accounts of such Rightsholders
     and persons other than the Company  shall be eliminated or reduced pro rata
     (based on the amount of securities owned  by  such  Rightsholders and other
     persons which carry registration rights) to the extent  necessary to reduce
     the total amount of  securities  to  be  included  in  such offering to the
     amount recommended by such  managing  underwriter(s) in its written opinion
     (or the Board of Directors in its resolution).

                    (ii)  Number of  Piggy-Back  Registrations;  Expenses.   The
     obligations  of  the  Company under this Paragraph 10(c) shall be unlimited
     with  respect to each Rightsholder.  Subject to the provisions of Paragraph
     10(e) hereof,  the Company will pay all Registration Expenses in connection
     with any registration  of Registerable Securities effected pursuant to this
     Paragraph 10(c), but the  Company  shall not be responsible for the payment
     of  any  underwriter's  discount,  commission  or  selling  concession   in
     connection therewith.

                    (iii)    Withdrawal or Suspension of Registration Statement.
     Notwithstanding anything contained to the contrary in this Paragraph 10(c),
     the  Company  shall  have  the absolute  right, whether before or after the
     giving of a Company Piggy-Back Notice or Holder Notice, to determine not to
     file  a  registration  statement  to which the

                                      -10-
<PAGE>

     Rightsholders shall have the right to include their Registerable Securities
     therein  pursuant  to this Paragraph 10(c), to withdraw  such  registration
     statement  or  to  delay  or  suspend  pursuing  the  effectiveness of such
     registration statement.  In the event of such  a  determination  after  the
     giving  of a Company Piggy-Back  Notice,  the  Company  shall  give  notice
     of  such  determination  to all Rightsholders  and,  thereupon, (A) in  the
     case  of a determination not to register or to withdraw  such  registration
     statement,  the  Company  shall  be  relieved  of its obligation under this
     Paragraph  10(c)  to  register  any  of  the  Registerable   Securities  in
     connection with such registration and (B) in the case of a determination to
     delay the registration, the  Company shall be permitted to delay or suspend
     the  registration  of  Registerable  Securities  pursuant to this Paragraph
     10(c) for the same period as the delay  in   the registration of such other
     securities.   No  registration  effected  under  this Paragraph 10(c) shall
     relieve  the  Company  of  its  obligation to effect any registration  upon
     demand   otherwise   granted   to   a  Rightsholder   under Paragraph 10(b)
     hereof or any other agreement with the Company.

          (d)  Registration Procedures.

               (i)  Obligations of the Company.  The Company will, in connection
     with  any  registration  pursuant  to  Paragraph  10(b)  or  (c) hereof, as
     expeditiously as possible:

          statement under the Securities Act on any  appropriate  form chosen by
          the Company, in its  sole discretion, which shall be available for the
          sale of all Registerable Securities  in  accordance  with the intended
          method(s)  of  distribution thereof set forth in all applicable Demand
          Requests,   Tag-Along   Requests  and  Holder  Notices,  and  use  its
          commercially  reasonable  best  efforts  to  cause  such  registration
          statement  to  become  effective  as  soon  thereafter  as  reasonably
          practicable; provided, that, at least five business days before filing
          with the Commission of such  registration statement, the Company shall
          furnish  to  each  Rightsholder  whose   Registerable  Securities  are
          included  therein  draft  copies  of   such  registration   statement,
          including all exhibits thereto and documents incorporated by reference
          therein, and, upon the reasonable  request  of  any such Rightsholder,
          shall continue to provide drafts of such registration  statement until
          filed, and,  after  such  filing, the Company shall, as diligently  as
          practicable, provide to each  such Rightsholders such number of copies
          of such registration statement, each amendment and supplement thereto,
          the prospectus included in such registration statement (including each
          preliminary   prospectus),   all    exhibits  thereto  and   documents
          incorporated by reference therein  and  such  other  documents as such
          Rightsholder  may   reasonably  request in  order  to  facilitate  the
          disposition of the Registerable  Securities owned by such Rightsholder
          and  included  in  such registration statement; provided, further, the
          Company shall modify or amend the registration statement as it relates
          to such Rightsholder as reasonably requested by such Rightsholder on a
          timely  basis,  and  shall  reasonably  consider  other changes to the
          registration  statement  (but  not  including  any exhibit or document
          incorporated  therein  by  reference)  reasonably  requested  by  such
          Rightsholder on a timely  basis, in  light  of the requirements of the
          Securities Act and any other  applicable laws and

                                      -11-

          regulations;  and  provided,  further,  that  the  obligation  of  the
          Company to effect such registration  and/or  cause  such  registration
          statement  to  become  effective,  may  be   postponed  for  (1)  such
          period of time when the financial statements  of  the Company required
          to be included in such registration statement  are  not available (due
          solely  to  the  fact  that such financial statements  have  not  been
          prepared in the regular course of  business  of  the  Company) or  (2)
          any other bona fide corporate purpose, but then  only for a period not
          to exceed 90 days;

                              (B)   prepare  and  file  with the Commission such
          amendments and post-effective  amendments to a registration  statement
          as may be necessary to keep such registration  statement effective for
          up to nine months; and cause the related prospectus to be supplemented
          by any  required  prospectus  supplement, and as so supplemented to be
          filed to the extent required pursuant  to  Rule  424 promulgated under
          the  Securities  Act,  during  such  nine-month  period; and otherwise
          comply  with  the provisions of the Securities Act with respect to the
          disposition   of   all  Registerable  Securities   covered   by   such
          registration statement during the applicable period in accordance with
          the intended method(s)  of disposition of such Registerable Securities
          set forth in such registration  statement, prospectus or supplement to

          Securities  are  included  in  such  registration  statement  and  the
          managing underwriter(s), if any, of an underwritten offering of any of
          the  Registerable  Securities included in such registration statement,
          and  confirm  such  advice  in  writing,  (1) when a prospectus or any
          prospectus supplement or post-effective amendment has been filed, and,
          with  respect  to  a  registration  statement  or  any  post-effective

          effectiveness of a  registration statement  or  the  initiation of any
          proceedings for that purpose, (4) if at  any  time the representations
          and warranties of the Company contemplated by clause  (1) of Paragraph
          10(d)(i)(J) hereof cease to be true and correct, (5) of the receipt by
          the Company of any notification with respect to the suspension  of the
          qualification of any of the Registerable Securities  for  sale  in any
          jurisdiction or  the  initiation  or threatening of any proceeding for
          such  purpose  and (6)  of  the happening of any event which makes any
          statement  made  in  the registration statement, the prospectus or any
          document  incorporated  therein  by reference untrue or which requires
          the making of any changes in the  registration statement or prospectus
          so   that   such   registration   statement,  prospectus  or  document
          incorporated  by  reference  will  not contain any untrue statement of
          material fact or omit to state any material fact required to be stated
          therein or necessary to make the statements therein not misleading;

          the  Registerable  Securities  included in such registration statement
          under such other securities or blue  sky laws of such jurisdictions as
          any Rightsholder whose Registerable Securities  are  included  in such
          registration statement reasonably requests  in writing and do any  and
          all  other  acts  and  things  which  may be necessary or advisable to
          enable  such  Rightsholder  to  consummate  the  disposition  in  such
          jurisdictions  of  such  Registerable  Securities;  provided, that the
          Company  will  not be required to (1) qualify generally to do business
          in any jurisdiction  where  it  would  not  otherwise  be  required to
          qualify  but  for this  Paragraph  10(d)(i)(E), (2) subject  itself to
          taxation  in  any such jurisdiction or (3) take any action which would
          subject it to general service of process in any such jurisdiction;

          Rightsholder  whose  Registerable  Securities  are  included  in  such

          financial  and  other  records,   pertinent  corporate  documents  and
          properties  of  the Company (collectively,  the "Records") as shall be
          reasonably  necessary  to  enable them to exercise their due diligence
          responsibility (or  establish a  due diligence defense), and cause the
          officers,  directors  and  employees  of the  Company  to  supply  all
          information  reasonably  requested by any such Inspector in connection
          with  such  registration  statement;  provided, that records which the

          confidential;

                              (G)   cooperate   with   the   Rightsholder  whose
          Registerable  Securities  are  included in such registration statement
          and  the  managing  underwriter(s), if any,   to facilitate the timely
          preparation  and  delivery  of certificates representing  Registerable

               (ii)  Obligations  of  Rightsholders.   In  connection  with  any
     registration  of  Registerable  Securities  of  a  Rightsholder pursuant to
     Paragraph 10(b) or (c) hereof:

                              (A) The Company may require that each Rightsholder
          whose  Registerable  Securities  are  included  in  such  registration
          statement  furnish  to  the  Company  such  information  regarding the
          distribution of such Registerable Securities  and such Rightsholder as
          the Company may from time to time reasonably request in writing; and

                              (B)  Each Rightsholder, upon receipt of any notice
          from  the  Company of the happening of any event of the kind described
          in  clauses (2), (3), (5)  and (6) of  Paragraph  10(d)(i)(C)  hereof,
          shall  forthwith  discontinue  disposition  of Registerable Securities
          pursuant  to  the  registration  statement  covering such Registerable
          Securities  until  such  Rightsholder's  receipt  of the copies of the
          supplemented  or  amended  prospectus  contemplated  by  clause (1) of
          Paragraph 10(d)(i)(C) hereof, or until such Rightsholder is advised in
          writing  (the "Advice") by  the Company that the use of the applicable
          prospectus  may  be resumed, and until  such Rightsholder has received
          copies   of   any  additional   or  supplemental  filings  which   are
          incorporated  by  reference  in  or to be attached to or included with
          such prospectus, and, if so directed by the Company, such Rightsholder
          will  deliver  to  the  Company  (at  the  expense of the Company) all
          copies,  other  than  permanent  file copies then in the possession of
          such   Rightsholder,   of   the   current  prospectus  covering   such
          Registerable  Securities  at  the  time of receipt of such notice; the
          Company shall have the right to demand that such Rightsholder or other
          holder verify its agreement to the  provisions of this Paragraph 10(d)
          (ii)(B)  in  any Demand Request, Tag-Along Request or Holder Notice of
          the   Rightsholder  or  in  a   separate  document  executed  by   the
          Rightsholder.

          (e)   Registration  Expenses. All expenses incident to the performance
of  or  compliance  with  this  Agreement  by  the  Company,  including, without
imitation,  all  registration  and  filing  fees  of  the  Commission,  National
Association  of Securities  Dealers,  Inc. and other agencies, fees and expenses
of compliance with  securities  or  blue sky laws (including reasonable fees and
disbursements  of counsel  in  connection  with  blue  sky qualifications of the
Registerable Securities),  rating   agency fees,  printing  expenses,  messenger
and delivery expenses,  internal expenses  (including,  without limitation,  all
salaries  and  expenses  of  its  officers  and  employees   performing legal or
accounting   duties),  the  fees  and expenses  incurred in connection  with the
listing,  if any, of the Registerable  Securities on any securities exchange and
fees  and  disbursements  of  counsel   for   the   Company  and  the  Company's
independent  certified   public   accountants  (including  the  expenses  of any
special  audit or "cold  comfort" letters required  by  or  incidental  to  such
performance),   Securities  Act  or  other  liability  insurance (if the Company
elects to obtain such insurance),  the fees and expenses of any special  experts
retained by the Company in connection with  such  registration and  the fees and
expenses of any other person retained by the Company  (but  not  including   any
underwriting     discounts  or   commissions   attributable  to   the  sale   of
Registerable  Securities or other  out-of-pocket expenses of the  Rightsholders,
or  the agents who act on their  behalf,  unless reimbursement  is  specifically
approved  by the  Company)  will be borne by the Company.  All such

                                      -15-
<PAGE>


expenses  are  herein  referred  to  as "Registration Expenses." Notwithstanding
the  foregoing,  the Company  shall not be required to pay for any  Registration
Expenses  of any Demand  Registration  if such  Demand  Request is  subsequently
withdrawn  at the  request  of the  holders of a  majority  of the  Registerable
Securities included in such Demand Registration (in which case all Rightsholders
which  requested  the  withdrawal  of the  Demand  Registration  shall bear such
expenses pro rata);  provided  that,  if, at the time of such  withdrawal,  such
Rightsholders  have  learned  of a  material  adverse  change in the  condition,
business or prospects of the Company  from that known to such  Rightsholders  at
the time of their Demand Request,  such  Rightsholders  shall not be required to
pay any of such expenses. In either event, if such Rightsholders pay in full the
expenses of such withdrawn Demand Registration,  such Rightsholders shall retain
the right to one Demand Registration.

          (f)  Indemnification: Contribution.

                    (i)   Indemnification by the Company.  The Company agrees to
     indemnify and hold harmless,  to  the  full  extent  permitted by law, each
     Rightsholder, its officers and directors and each person  who controls such
     Rightsholder  (within  the  meaning of the Securities Act), if any, and any
     agent thereof against all losses, claims, damages, liabilities and expenses
     incurred by such party pursuant  to  any actual or threatened suit, action,
     proceeding  or  investigation  (including  reasonable  attorney's fees  and
     expenses of investigation)  arising  out  of  or  based  upon any untrue or
     alleged untrue statement of a material fact contained  in  any registration
     statement, prospectus or preliminary prospectus or any omission  or alleged
     omission to state therein a material fact required to be stated  therein or
     necessary to make the  statements  therein (in the case of a prospectus, in
     the light of the circumstances under  which they were made) not misleading,
     except insofar as the same arise out of or are  based upon, any such untrue
     statement  or  omission  based  upon   information  with  respect  to  such
     Rightsholder  furnished  in  writing  to  the  Company by such Rightsholder
     expressly for use therein.

                    (ii)  Indemnification by  Rightsholder.  In  connection with
     any registration statement in which  a  Rightsholder is participating, each
     such Rightsholder  will  be  required  to furnish to the Company in writing
     such  information  with  respect  to  such  Rightsholder  as  the   Company
     reasonably  requests for  use  in  connection  with  any  such registration
     statement or  prospectus, and  each Rightsholder agrees to the extent it is
     such a holder of Registerable  Securities  included  in  such  registration
     statement, and each  other such  holder of Registerable Securities included
     in such Registration Statement  will  be  required  to agree, to indemnify,
     to  the  full extent permitted by  law,  the  Company,  the  directors  and
     officers of  the  Company  and each person who controls the Company (within
     the meaning of the Securities  Act)  and  any  agent  thereof,  against any
     losses, claims,  damages,  liabilities  and  expenses (including reasonable
     attorney's  fees  and  expenses  of  investigation  incurred  by such party
     pursuant  to  any  actual  or  threatened   suit,  action,  proceeding   or
     investigation  arising  out  of  or based upon any untrue or alleged untrue
     statement of a material  fact  or  any  omission  or  alleged omission of a
     material fact necessary,  to make  the statements therein (in the case of a
     prospectus, in  the  light  of the circumstances under which they are made)
     not  misleading, to  the  extent,  but only to the extent, that such untrue
     statement  or  omission  is   based  upon  information  relating

                                      -16-
<PAGE>

     to such  Rightsholder  or other holder  furnished in writing to the Company
     expressly for use therein.

                    (iii)     Conduct  of Indemnification  Proceedings. Promptly
     after receipt by an indemnified party under this Paragraph 10(f) of written
     notice of the commencement of any action, proceeding, suit or investigation
     or threat thereof made  in writing for which  such  indemnified  party  may
     claim  indemnification  or  contribution  pursuant to this Agreement,  such
     indemnified party  shall  notify  in writing the indemnifying party of such
     commencement or threat; but the omission  so  to  notify  the  indemnifying
     party shall not relieve the indemnifying party from any liability which the
     indemnifying party may have to any indemnified party (A) hereunder,  unless
     the  indemnifying  party  is  actually prejudiced thereby, or (B) otherwise
     than  under  this  Paragraph  10(f).  In  case  any  such  action,  suit or
     proceeding  shall  be  brought  against  any  indemnified  party,  and  the
     indemnified party shall notify  the  indemnifying party of the commencement
     thereof, the indemnifying party shall  be  entitled  to participate therein
     and the indemnifying party shall assume the defense thereof,  with  counsel
     reasonably satisfactory to the indemnified party, and the obligation to pay
     all expenses relating thereto.  The indemnified party shall have the  right
     to employ separate counsel  in  any  such action, suit or proceeding and to
     participate  in  the  defense  thereof,  but  the fees and expenses of such
     counsel shall be at the expense of such indemnified  party  unless  (A) the
     indemnifying  party  has  agreed  to  pay  such  fees and expenses, (B) the
     indemnifying party shall have failed to assume the defense of such  action,
     suit or proceeding  or  to  employ  counsel  reasonably satisfactory to the
     indemnified party therein or to pay all expenses  relating  thereto  or (C)
     the named parties to any such action or proceeding (including any impleaded
     parties) include both the indemnified party and the indemnifying  party and
     the  indemnified party shall have been advised by counsel that there may be
     one  or  more  legal  defenses available to the indemnified party which are
     different  from  or additional to those available to the indemnifying party
     and  which may result in a conflict between the indemnifying party and such
     indemnified party  (in  which  case,  if the indemnified party notifies the
     indemnifying  party  in writing that the indemnified party elects to employ
     separate counsel at the expense of the indemnifying party, the indemnifying
     party  shall  not  have  the  right to assume the defense of such action or
     proceeding  on  behalf  of  the  indemnified  party;  it  being understood,
     however, that the  indemnifying party  shall  not,  in  connection with any
     one such action, suit  or  proceeding or separate but substantially similar
     or related actions, suits or proceedings  in  the same jurisdiction arising
     out of the  same  general  allegations  or circumstances, be liable for the
     fees and expenses of more than one separate  firm of attorneys  at any time
     for the indemnified party, which firm shall be designated in writing by the
     indemnified party).

                    (iv)  Contribution.   If the indemnification provided for in
     this Paragraph 10(f) from  the indemnifying  party  is  unavailable  to  an
     indemnified party hereunder  in  respect  of  any  losses, claims, damages,
     liabilities or  expenses  referred to therein, then the indemnifying party,
     in lieu  of  indemnifying  such  indemnified party, shall contribute to the
     amount  paid  or  payable  by  such  indemnified  party as a result of such
     losses, claims, damages, liabilities or expenses (A) in such  proportion as
     is  appropriate   to  reflect  the   relative  benefits  received  by   the
     indemnifying party  on  the one hand and the indemnified party on the other

                                      -17-
<PAGE>

     or (B) if the allocation  provided  by clause (A) above is not permitted by
     applicable  law,  in  such proportion as is appropriate to reflect not only
     the  relative  benefits  received by the indemnifying party on the one hand
     and  the indemnified party on the other but also the relative  fault of the
     indemnifying  party  and indemnified party, as well as any  other  relevant
     equitable considerations.  The  relative  fault of such indemnifying  party
     and  the  indemnified  parties  shall  be determined by reference to, among
     other  things,  whether  any  action in question, including any  untrue  or
     alleged untrue statement of a material fact or omission or alleged omission
     to state a material fact,  has  been  made  by,  or  relates to information
     supplied  by,  such indemnifying  party  or  indemnified  parties, and  the
     parties' relative  intent, knowledge, access to information and opportunity
     to correct or prevent such action.  The  amount paid or payable by a  party
     as  a  result of  the  losses,  claims,  damages,  liabilities and expenses
     referred  to  above  shall be  deemed to include, subject to the limitation
     set  forth  in  Paragraph  10(f)(v), any legal or  other  fees  or expenses
     reasonably  incurred  by  such  party  in connection with any investigation
     or proceeding.

                    The   parties   hereto  agree  that it would not be just and
     equitable  if  contribution  pursuant  to  this  Paragraph  10(f)(iv)  were
     determined by  pro  rata  allocation  or  by any other method of allocation
     which does not  take  into  account  the  equitable considerations referred
     to  in  clauses (A) and (B) of  the  immediately  preceding  paragraph.  No
     person  guilty  of  fraudulent  misrepresentation  (within  the  meaning of
     Section 11(f) of the Securities Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation.

                    (v)  Limitation.  Anything to the contrary contained in this
     Paragraph  10(f)  or  in  Paragraph  10(g)  notwithstanding,  no  holder of
     Registerable   Securities   shall   be   liable  for  indemnification   and
     contribution payments aggregating an amount in excess of the maximum amount
     received  by  such  holder  in  connection  with  any  sale of Registerable
     Securities as contemplated herein.

          (g)   Participation in Underwritten Registration.  No Rightsholder may
participate  in any underwritten registration hereunder unless such Rightsholder
(i) agrees to  sell  such  holder's  securities  on  the  basis  provided in any
underwriting arrangements approved by the persons entitled hereunder  to approve
such arrangements and to  comply  with  Rules 10b-6 and 10b-7 under the Exchange
Act and (ii) completes and executes all  questionnaires, appropriate and limited
powers of attorney, escrow agreements, indemnities, underwriting  agreements and
other  documents  reasonably  required  under  the  terms  of  such underwriting
arrangement;  provided,  that  all  such  documents shall be consistent with the
provisions of Paragraph 10(e) hereof.

11.  MISCELLANEOUS.

          This Warrant Certificate and any term hereof may be  changed,  waived,
discharged  or terminated  only by an instrument in writing  signed by the party
against which  enforcement of such change,  waiver,  discharge or termination is
sought.  This  certificate  is deemed to have been delivered in the State of New
York and shall be construed and enforced in accordance  with and governed by

Warrants shall expire at the Expiration Time.
