THIS  CERTIFIES  THAT  the  holder  of  this  Warrant  ("Holder") is entitled to
purchase  from  THE ZIG ZAG CORP. a Delaware corporation (hereinafter called the
"Company"), at the exercise price per share set forth below the number of shares
of  the  Company's  common  stock set forth above ("Common Stock"). The exercise
price  of  this  Warrant  is  $1.50 per share.  The warrants expire on the third
anniversary  of  the  date  hereof.

1.   Adjustment Provisions.     This Warrant is subject to the following further
     ---------------------
provisions:

     (a)  If the Company shall at any time while the Warrant remains outstanding
     issue Common Stock by way of dividend or other distribution on any stock of
     the  Company  or  effect  a  stock  split  or  reverse  stock  split of the
     outstanding  shares  of  Common  Stock,  the  Purchase  Price  shall  be
     proportionately  decreased  in  the  case  of  such  issuance  (on  the day
     following  the  date fixed for determining shareholders entitled to receive
     such  dividend  or  other distribution) or such stock split or increased in
     the  case of such reverse stock split (on the date that such stock split or
     reverse  stock  split  shall become effective), by multiplying the Purchase
     Price  in  effect  immediately  prior to the stock dividend, stock split or
     reverse  stock split by a fraction, the numerator of which is the number of
     shares  of  Common  Stock  outstanding  immediately  prior  to  such  stock
     dividend,  stock split or reverse stock split, and the denominator of which
     is  the number of shares of Common Stock outstanding immediately after such
     stock  dividend,  stock  split  or  reverse  stock  split.

     (b)  In  case  of  any  reclassification,  capital  reorganization or other
     change  of  outstanding shares of Common Stock of the Company (other than a
     change in par value or as a result of an issuance of Common Stock by way of
     dividend or other distribution or of a stock split or reverse stock split),
     or  in  case  of  any  consolidation  or merger of the Company with or into
     another  corporation  (other  than


<PAGE>
     a  merger  with  a subsidiary in which merger the Company is the continuing
     corporation  and  which  does  not  result in any reclassification, capital
     reorganization or other change of outstanding shares of Common Stock of the
     Company  issuable  upon exercise of this Warrant) or in case of any sale or
     conveyance  to another corporation or other change of outstanding shares of
     Common  Stock  of  the Company issuable upon exercise of the Warrant) or in
     case  of  any  sale or conveyance to another corporation of the property of
     the  Company  as  a  entirety  or substantially as an entirety, the Company
     shall  cause  effective  provision to be made so that the Holder shall have
     the  right thereafter, by exercising this Warrant, to purchase the kind and
     amount of shares of stock and other securities and property receivable upon
     such  reclassification,  capital  reorganization  or  other  change,
     consolidation,  merger,  sale  or  conveyance  that  the  Holder would have
     obtained  had  he  or  it  exercised this Warrant immediately prior to such
     reclassification,  capital  reorganization  or other change, consolidation,
     merger,  sale or conveyance. Any such provision shall include provision for
     adjustments  which  shall  be as nearly equivalent as may be practicable to
     the  adjustments  provided for in this Warrant. The foregoing provisions of
     this  Section  shall  similarly apply to successive consolidations, merger,
     sales  and  conveyances.

     (c)  If the Company shall at any time during the term of the PSB Agreement,
     issue  Common  Stock  (including securities convertible into or exercisable
     for  shares  of  Common Stock) or sell any shares of its Common Stock for a
     consideration  per  share  less  than  $1.00  (as adjusted for future stock
     splits,  stock  dividends  and  recapitalizations)  (the  Original Purchase
     Price), then the Original Exercise Price will be reduced to equal the price
     per  share  paid  by  such investor (the Future Purchase Price). Additional
     warrants  will  be  issued  by the Company such that the combined number of
     warrants  (the  original warrants plus adjustment warrants) shall equal the
     number  of  warrants obtained by dividing the original investment by Future
     Exercise  Price.

     (d)  If  the  Company shall declare or pay a dividend or other distribution
     on  any  Common  Stock,  by  way of distribution of assets or spin-off (but
     other  than  a  dividend  payable  solely  in  shares  of Common Stock or a
     periodic  cash  dividend payable out of the Company's net income), then the
     Purchase  Price  will  be reduced to a price determined by multiplying such
     Purchase  Price  by  a  fraction, (x) the numerator which shall be the fair
     market value of a share of Common Stock immediately prior to declaration of
     such  dividend  or  distribution (the "initial value") less the fair market
     value  of  such  dividend  or  distribution applicable to a share of Common
     Stock,  in  each case as determined in good faith by the Board of Directors
     of  the  Company  and  (y)  the denominator of which shall be the aforesaid
     initial  value.

     (e)  Upon  any  adjustment  of Purchase Price pursuant to this Section, the
     Holder  shall  thereafter  (until  another  such adjustment) be entitled to
     purchase  upon  the  exercise  of  the  Warrant  with respect to which such
     adjustment  occurred,  at  the  new  Purchase  Price thereof, the number of
     shares,  calculated  to the nearest full share, obtained by multiplying the
     number  of shares of stock initially issuable upon exercise of such Warrant
     by the Purchase Price thereof in effect on the date hereof and dividing the
     product  so  obtained  by  the  new  Purchase  Price  thereof.

2.   This Warrant and the Common Stock issuable on exercise of this Warrant (the
     "Underlying  Shares")  may  be transferred, sold, assigned or hypothecated,
     only  if  registered  by  the Company under the Securities Act of 1933 (the
     "Act") or if the Company has received from counsel to the Company a written
     opinion  to  the  effect that registration of the Warrant or the Underlying
     Shares  is not necessary in connection with such transfer, sale, assignment
     or  hypothecation.  The  Warrant  and  the  Underlying  Shares  shall  be
     appropriately  legended  to  reflect  this  restriction  and  stop transfer
     instructions shall apply. The Holder shall through its counsel provide such
     information  as  is  reasonably  necessary in connection with such opinion.

3.   Registration  Rights
     --------------------

     (a)  Piggy-Back  Registration Rights.  If, at any time the Company proposes
          --------------------------------
     to  prepare  and file a registration statement or post-effective amendments
     thereto  covering  the  Common  Stock of the Company for the Company or for
     selling stockholders of the Company (other than in connection with a merger
     or  acquisition,  pursuant to Form S-8 or successor form (collectively, the
     "Statement"),  the  Company  will give written notice by registered mail or
     facsimile  at  least  ten  (10)  days  prior  to  the  filing  of each such
     Statement, to the Holder or Holders of the Warrant or warrant Shares of its
     intention  to  do  so.  If  the Holder or Holders of the Warrant or Warrant
     Shares  notify  the  Company within five (5) days after receipt of any such
     notice  ofits  or their desire to include all Warrant Shares in the Company
     owned  by  such Holder in such proposed Statement, the Company shall afford
     such  Holder  or  Holders  the  opportunity to have all such Warrant Shares
     registered  under such Statement at the Company's sole cost and expense and
     at  no  cost expense to such Holder or Holders; provided, however, that if,
     in  written opinion of the Company's managing underwriter, the inclusion of
     the  Warrant Shares, when added to the Common Stock being registered by the
     Company  and  any  other  selling  stockholders  participating  in  such
     underwritten  offering,  will  exceed  the  maximum amount of the Company's
     Common Stock which can be marketed, (i) at a price reasonably affecting the
     entire  offering,  then the current market value, or (ii) without otherwise
     materially  adversely  affecting  the entire offering, then the Company may
     exclude from such offering all or a portion of the Warrant Shares requested
     to be registered, such exclusion to be proportionate with any other selling
     stockholder.  A  Holder or Holders may not elect register only a portion of
     its  or  their  shares.

     The  Company  agrees  to use its best efforts to cause such Statement to be
     filed  and to become effective, and to keep the Prospectus included in such
     Statement,  current either through the filing of periodic reports under the
     Exchange  Act,  or by filing Post-Effective Amendments to the Statement, so
     as  to permit the public sale of the Warrant Shares for a period of six (6)
     consecutive  months  from  the date such Statement is declared effective by
     the  Securities and Exchange Commission. The Holder or Holders acknowledge,
     however,  that  prior  to  effecting  any  sales of the Warrant Shares, the
     Holder  or  Holders  will  confirm  with  the  Company  that the Prospectus
     included  in  the  Statement  is  up-to-date  and  that  such shares may be
     lawfully  sold.  The Holder of the Warrant Shares has no other registration
     rights  with  respect  to the underlying Warrant Shares except those rights
     specified  in  Sections  3(a)  and  3(b)  of  this  Warrant.

     Notwithstanding the provisions of this Section 3(a), the Company shall have
     the  right at any time after it shall have given written notice pursuant to
     this  Section 3(a) (irrespective of whether a written request for inclusion
     of  any  such Warrant Shares shall have been made) to elect not to file any
     such proposed Statement, or to withdraw the same after the filing but prior
     to  the  effective  date  thereof.

     (b)  Demand Registration Rights.  In the event that the Warrants shares are
          ---------------------------
     excluded  from registration as described in 3(a) above, the Company will at
     its own expense file a registration statement at the next earliest possible
     date following completion of its offering and include the shares underlying
     the  Warrants.  Such  registration  statement  may  be  a  post  effective
     amendment,  registration  under  Form S-3 or any other registration process
     available to it under current or then existing SEC guidelines. It is hereby
     expressly  agreed to between the parties that the Company shall, as soon as
     practicable  but  in  any  event  within  90  days  following  the  initial
     registration, cause a registration statement of the Common Stock underlying
     the  Warrants  to  be  filed  under  the  Securities


<PAGE>
     Exchange  Act  with  respect  to  an  offering, in part, of the Registrable
     Securities  (a  "Demand  Registration"). In the event that the Registration
     Statement  is not filed by the 90th day following the offering, the Company
     agrees  that it is in default under the terms of this Agreement. The Holder
     shall have all rights and remedies available to him to seek damages as well
     as  to  seek  specific  performance.

4.   Any permitted assignment of this Warrant shall be effected by the Holder by
     (i)  executing  the form of assignment at the end hereof, (ii) surrendering
     the  Warrant  for cancellation at the office of the Company, accompanied by
     the  opinion  of counsel to the Company referred to above; and (iii) unless
     in  connection  with  an  effective registration statement which covers the
     sale  of this Warrant and or the shares underlying the Warrant, delivery to
     the  Company  of a statement by the transferee (in a form acceptable to the
     Company  and its counsel) that such Warrant is being acquired by the Holder
     for investment and not with a view to its distribution or resale; whereupon
     the  Company  shall  issue,  in  the  name or names specified by the Holder
     (including the Holder) new Warrants representing in the aggregate rights to
     purchase  the  same  number  of Shares as are purchasable under the Warrant
     surrendered.  Such  Warrants shall be exercisable immediately upon any such
     assignment  of the number of Warrants assigned. The transferor will pay all
     relevant transfer taxes. Replacement warrants shall bear the same legend as
     is  borne  by  this  Warrant.

4    (a)  The  term  "Holder"  should  be deemed to include any permitted record
     transferee  of  this  Warrant.

5.   The  Company covenants and agrees that all shares of Common Stock which may
     be  issued  upon  exercise  hereof will, upon issuance, be duly and validly
     issued, fully paid and non-assessable and no personal liability will attach
     to  the  holder  thereof.  The  Company  further covenants and agrees that,
     during  the periods within which this Warrant may be exercised, the Company
     will  at  all  times  have  authorized  and reserved a sufficient number of
     shares  of  Common Stock for issuance upon exercise of this Warrant and all
     other  Warrants.

6.   This  Warrant  shall  not  entitle the Holder to any voting rights or other
     rights  as  a  stockholder  of  the  Company.

7.   In  the  event  that  as a result of reorganization, merger, consolidation,
     liquidation,  recapitalization, stock split, combination of shares or stock
     dividends payable with respect to such Common Stock, the outstanding shares
     of  Common  Stock  of the Company are at any time increased or decreased or
     changed  into or exchanged for a different number or kind of share or other
     security  of  the  Company  or  of  another  corporation,  then appropriate
     adjustments  in the number and kind of such securities then subject to this
     Warrant  shall  be made effective as of the date of such occurrence so that
     the  position of the Holder upon exercise will be the same as it would have
     been  had  it  owned immediately prior to the occurrence of such events the
     Common  Stock  subject  to  this  Warrant.  Such  adjustment  shall be made
     successively  whenever  any  event listed above shall occur and the Company
     will notify the Holder of the Warrant of each such adjustment. Any fraction
     of  a share resulting from any adjustment shall be eliminated and the price
     per  share  of  the  remaining  shares  subject  to  this  Warrant adjusted
     accordingly.

8.   The  rights represented by this Warrant may be exercised at any time within
     the  period  above  specified  by  (i)  surrender of this Warrant (with the
     purchase  form  at  the  end  hereof  properly  executed)  at the principal
     executive  office  of  the  Company  (or such other office or agency of the
     Company  as  it  may  designate  by  notice in writing to the Holder at the
     address  of  the  Holder


<PAGE>
     appearing  on the books of the Company); (ii) payment to the Company of the
     exercise  price  for  the number of Shares specified in the above-mentioned
     purchase  form  together  with applicable stock transfer taxes, if any, or,
     Warrants  of  the  Company  with  a fair market value equal to the Purchase
     Price  in  payment  of  the  Purchase  Price for the number of whole shares
     specified.  For  purposes of making payment of the Purchase Price by way of
     Shares  of Common Stock of the Company or Warrants of the Company, the fair
     market  value  of  any  share of Common Stock shall be equal to the closing
     price  of  a Share of Common Stock of NASDAQ or other principal exchange on
     which  such  Shares  are listed as of the business day immediately prior to
     the  day  of  exercise  and  the fair market value per Share of any Warrant
     shall  be  equal  to the difference between the aforesaid closing price per
     Share  and  the Purchase Price of the Warrant; provided however, that if at
     the  time  of determination the Shares are not listed, then the fair market
     value  per  share  shall  be deemed to have a value as determined by a good
     faith  determination  of  the  Board of Directors of the Company. and (iii)
     unless  in connection with an effective registration statement which covers
     the  sale of the shares underlying the Warrant, the delivery to the Company
     of  a  statement by the Holder (in a form acceptable to the Company and its
     counsel)  that  such Shares are being acquired by the Holder for investment
     and  not  with  a  view  to  their  distribution  or  resale.

9.   The  certificates  for  the Common Stock so purchased shall be delivered to
     the  Holder  within a reasonable time, not exceeding ten (10) business days
     after  all  requisite  documentation  has  been  provided, after the rights
     represented  by this Warrant shall have been so exercised, and shall bear a
     restrictive  legend  with  respect  to  any  applicable  securities  laws.

     This Warrant shall be governed by and construed in accordance with the laws
     of  the  State  of  New  York.  The  New  York  courts shall have exclusive
     jurisdiction  over  this instrument and the enforcement thereof. Service of
     process  shall be effective if by certified mail, return receipt requested.
     All  notices  shall be in writing and shall be deemed given upon receipt by
     the  party  to  whom  addressed.  This  instrument  shall be enforceable by
     decrees  of  specific  performances  well  as  other  remedies.



IN  WITNESS  WHEREOF,  THE ZIG ZAG CORP. has caused this Warrant to be signed by
its duly authorized officers under Its corporate seal, and to be dated as of the
date  set  forth  above.

                                         THE  ZIG  ZAG CORP.
