      registration under the Securities Act and any applicable state securities
      or blue sky laws of this Warrant or such Warrant Shares, as the case may

      accordance with the statement of intention delivered by said holder to the
      Company.

            (2) If, in the opinion of said counsel, concurred in by counsel to

      2.6 EXPENSES OF DELIVERY OF WARRANTS. The Company shall pay all expenses,

                                   ARTICLE III

                            ANTI-DILUTION PROVISIONS

      3.1 ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The
Exercise Price shall be subject to adjustment from time to time as hereinafter
in this Article III provided. Upon each adjustment of the Exercise Price, except
pursuant to 3. 1(a)(vi) and 3. 1(a)(vii), the registered holder of the Warrant
shall thereafter be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of shares of the Common Stock (calculated to the
nearest whole share pursuant to Section 1.2) obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares of the Common Stock purchasable pursuant hereto immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

      (a)    EXERCISE PRICE  ADJUSTMENTS.  The Exercise Price shall be subject
to adjustment from time to time as follows:

                                      5

             (i) ISSUANCES OF COMMON STOCK. (A) If, at any time, during the
      period (the "Note Period") that any principal amount is outstanding on the
      Notes (as defined in the Purchase Agreement), the Company shall issue any
      Common Stock other than Excluded Stock or Additional Excluded Stock (as
      hereinafter defined) without consideration or for a consideration per
      share less than the Exercise Price applicable immediately prior to such
      issuance, the Exercise Price in effect immediately prior to each such
      issuance shall immediately (except as provided below) be reduced to the
      price equal to the greater of (I) the result obtained by dividing (aa) the
      consideration, if any, received by the Company upon such issuance by (b)
      the total number of shares of Common Stock issued by the Company upon such
      issuance and (II) $0.05 or

            (B) If, at any time, subsequent to the Note Period, the Company
      shall issue any Common Stock other than Excluded Stock (as hereinafter
      defined) without consideration or for a consideration per share less than
      the Exercise Price applicable immediately prior to such issuance, the
      Exercise Price in effect immediately prior to each such issuance shall
      immediately (except as provided below) be reduced to the price determined
      as follows:
       by dividing (A) an amount equal to the sum of (x) the number of shares of
       Common Stock outstanding immediately prior to such issuance multiplied by
       the Exercise Price immediately prior to such issuance and ~) the
       consideration, if ~ received by the Company upon such issuance, by ~) the
       total number of shares of Common Stock outstanding immediately after such
       issuance;

provided, however, that if the number of shares of Common Stock (other than
Excluded Stock) issued or reserved or agreed to be reserved for issuance by the
Company should at any time exceed 5 % of the Company's issued and outstanding
shares of Common Stock none of such shares (whether or not previously issued or
reserved for issuance by the Company) shall be considered Additional Excluded
Stock for purposes of determining the Exercise Price adjustment in Section 3.1
(a) (i) (A) and the Exercise Price shall be readjusted accordingly in accordance
with the provisions of Section 3. 1(a)(i)(A) using the lowest per share price of
any Common Stock so issued or reserved or agreed to be reserved for issuance.

      For the purpose of any adjustment of the Exercise Price pursuant to this
clause (i) of this Section 3.1(a), the following provisions shall be applicable:

                  (A) CASH. In the case of the issuance of Common Stock for
            cash, the amount of the consideration received by the Company shall
            be deemed to be the amount of the cash proceeds received by the
            Company for such Common Stock before deducting therefrom any
            reasonable discounts, commissions, taxes or other expenses allowed,
            paid or incurred by the Company for any underwriting or otherwise in
            connection with the issuance and sale thereof.

                  (B) CONSIDERATION OTHER THAN CASH. In the case of the issuance
            of Common Stock (otherwise than upon the conversion of shares of
            capital stock or other securities of the Company) for a
            consideration in whole or in part other than

                                      6

            cash, including securities acquired in exchange therefor (other than
            securities by their terms so exchangeable), the consideration other
            than cash shall be deemed to be the fair value thereof as determined
            by the Board of Directors in good faith, irrespective of any
            accounting treatment.

      (ii) OPTIONS AND CONVERTIBLE SECURITIES ETC. In case, at any time, the
Company shall issue any (i) options, warrants or other rights to purchase or
acquire Common Stock other than Excluded Stock (whether or not at the time
exercisable), (ii) securities by their terms convertible into or exchangeable
for Common Stock (whether or not at the time so convertible or exercisable) or
(i~) options, warrants or rights to purchase such convertible or exchangeable
securities (whether or not at the time exercisable), and such securities so
issued or rights granted in the cases of (i), (ii) or (iii) are not Excluded
Stock, the Exercise Price in effect immediately prior to each such issuance
shall immediately (except as provided below) be reduced to the price determined
in accordance with Section 3. 1(a)(i) and the following:

            (1) the aggregate maximum number of shares of Common Stock
      deliverable upon exercise of such options, warrants or other rights to
      purchase or acquire Common Stock shall be deemed to have been issued at
      the time such options, warrants or rights were issued and for a
      consideration equal to the consideration (determined in the manner
      provided in subclauses (A) and (B) above), if any, received by the Company
      upon the issuance of such options, warrants or rights plus the minimum
      purchase price provided in such options, warrants or rights for the Common
      Stock covered thereby;

            (2) the aggregate maximum number of shares of Common Stock
      deliverable upon conversion of or in exchange for any such convertible or
      exchangeable securities, or upon the exercise of options, warrants or
      other rights to purchase or acquire such convertible or exchangeable
      securities and the subsequent conversion or exchange thereof, shall be
      deemed to have been issued at the time such securities were issued or such
      options, warrants or rights were issued and for a consideration equal to
      the consideration, if any, received by the Company for any such securities
      and related options, warrants or rights (excluding any cash received on
      account of accrued interest or accrued dividends), plus the additional
      consideration, if any, to be received by the Company upon the conversion
      or exchange of such securities and the exercise of any related options,
      warrants or rights (the consideration in each case to be determined in the
      manner provided in subclauses (A) and (B) above);

            (3) on any change in the number of shares of Common Stock
      deliverable upon exercise of any such options, warrants or rights or
      conversion or of exchange for such convertible or exchangeable securities
      or any change in the consideration to be received by the Company upon such
      exercise, conversion or exchange, including, but not limited to, a change
      resulting from the antidilution provisions

                                 7

       thereof, the Exercise Price as then in effect shall forthwith be
       readjusted to such Exercise Price as would have been obtained had an
       adjustment been made upon the issuance of such options, warrants or
       rights not exercised prior to such change, or securities not converted or
       exchanged prior to such change, on the basis of such change;

            (4) on the expiration or cancellation of any such options, warrants
      or rights, or the termination of the right to convert or exchange such
      convertible or exchangeable securities, if the Exercise Price shall have
      been adjusted upon the issuance thereof, the Exercise Price shall
      forthwith be readjusted to such Exercise Price as would have been obtained
      had an adjustment been made upon the issuance of such options, warrants,
      rights or securities on the basis of the issuance of only the number of
      shares of Common Stock actually issued upon the exercise of such options,
      warrants or rights, or upon the conversion or exchange of such securities;
      and

            (5) if the Exercise Price shall have been adjusted upon the issuance
      of any such options, warrants, rights or convertible or exchangeable
      securities, no further adjustment of the Exercise Price shall be made for
      the actual issuance of Common Stock upon the exercise, conversion or
      exchange thereof;

PROVIDED, HOWEVER, that no increase in the initial Exercise Price shall be made
pursuant to this Section 3.1 (a)(ii).

      (iii) EXCLUDED STOCK. "Excluded Stock" shall mean shares of Common Stock
issued or reserved or agreed to be reserved for issuance by the Company (A)
under options, warrants, or other securities convertible or exercisable into
Common Stock (whether pursuant to a stock option plan or otherwise), provided
the same are issued to officers, directors or employees of the Company and
provided that the aggregate number of shares of Common Stock issued or issuable
under this clause (A) shall not exceed 10% of the Company's issued and
outstanding shares of Common Stock, (B) pursuant to anti-dilution provisions or
rights with respect to any other presently issued and outstanding securities of
the Company convertible into, exchangeable for, or giving the holder thereof the
option or right to purchase shares of Common Stock, (C) pursuant to warrants to
purchase 1,111,100 shares of Common Stock issued under the Purchase Agreement
dated as of December 19,1994, (D) pursuant to up to 950,000 warrants issued to
GTI Partners LLC pursuant to the Consulting Agreement dated May 13, 1998, and
pursuant up to 10,000,000 warrants to be issued to Ghulam Bombaywala, both as
authorized by the Board of Directors of the Company on May 1, 1998, or (E)
pursuant to a stock dividend, subdivision or split-up covered by clause (iv) of
this Section 3.1(a). "Additional Excluded Stock" shall mean shares of Common
Stock (other than Excluded Stock) issued or reserved or agreed to be reserved
for issuance by the Company whether directly or under options, warrants, or
other securities convertible or exercisable into Common Stock, provided that the
aggregate number of shares of Common Stock issued or issuable under such
options,

                                      8

warrants, or other convertible securities shall not exceed 5% of the Company's
issued and outstanding shares of Common Stock.

      (iv) STOCK DIVIDENDS AND SPLITS. If the number of shares of Common Stock
outstanding at any time after the date of this Warrant is increased by a stock
dividend payable in shares of Common Stock or increased or decreased by a
subdivision or split-up of shares of Common Stock, then immediately after the
record date fixed for the determination of holders of Common Stock entitled to
receive such stock dividend or the effective date of such subdivision or
split-up, as the case may be, the Exercise Price shall be appropriately adjusted
so that the adjusted Exercise Price shall bear the same relation to the Exercise
Price in effect immediately prior to such adjustment as the total number of
shares of Common Stock outstanding immediately prior to such action shall bear
to the total number of shares of Common Stock outstanding immediately after such
action.

      (v) COMBINATION OF STOCK. If the number of shares of Common Stock
outstanding at any time after the date of issuance of this Warrant is decreased
by a combination of the outstanding shares of Common Stock, then, immediately
after the effective date of such combination, the Exercise Price shall be
appropriately adjusted so that the adjusted Exercise Price shall bear the same
relation to the Exercise Price in effect immediately prior to such adjustment as
the total number of shares of Common Stock outstanding immediately prior to such
action shall bear to the total number of shares of Common Stock outstanding
immediately after such action.

      (vi) REORGANIZATIONS. ETC. In case of any capital reorganization of the
Company, or of any reclassification of the Common Stock, or in case of the
consolidation of the Company with or the merger of the Company with or into any
other Person or of the sale, lease or other transfer of all or substantially all
of the assets of the Company to any other Person, this Warrant shall, after such
capital reorganization, reclassification, consolidation, merger, sale, lease or
other transfer, be exercisable for the number of shares of stock or other
securities or property to which the Common Stock issuable (at the time of such
capital reorganization, reclassification, consolidation, merger, sale, lease or
other transfer) upon exercise of this Warrant would have been entitled to
receive upon such capital reorganization, reclassification, consolidation,
merger, sale, lease or other transfer if such exercise had taken place; and in
any such case, if necessary, the provisions set forth herein with respect to the
rights and interests thereafter of the holder of this Warrant shall be
appropriately adjusted so as to be applicable, as nearly as may reasonably be,
to any shares of stock or other securities or property thereafter deliverable on
the exercise of this Warrant. In case of any distribution by the Company of any
security (including rights or warrants to subscribe for any such securities but
excluding Common Stock and any securities referred to in Section 3. l(a)(ii)) of
the Company, evidences of its indebtedness, cash or other assets to all of the
holders of its Common Stock, then in each such case the Exercise Price in effect
thereafter shall be determined by multiplying the Exercise Price in effect
immediately prior thereto by a fraction the numerator of which shall be the
total number of outstanding shares of Common Stock multiplied by the

                                      9

Current Market Price on the record date mentioned below, less the fair market
value (as determined in good faith by the Board of Directors) of the securities,
evidences of its indebtedness, cash or other assets distributed by the Company
and the denominator of which shall be the total number of outstanding shares of
Common Stock multiplied by the Current Market Price; such adjustment shall
become effective as of the record date for the determination of stockholders
entitled to receive such distribution. The subdivision or combination of shares
of Common Stock issuable upon exercise of this Warrant at any time outstanding
into a greater or lesser number of shares of Common Stock (whether with or
without par value) shall not be deemed to be a reclassification of the Common S
tock of the Company for the purposes of this clause (vi).

      (vii) ROUNDING OF CALCULATIONS: MINIMUM ADJUSTMENT. All calculations under
this Section 3.1(a) shall be made to the nearest cent or to the nearest whole
share (as provided in Section 1.2) share, as the case may be. Any provision of
this Section 3.1 to the contrary notwithstanding, no adjustment in the Exercise
Price shall be made if the amount of such adjustment would be less than $.05,
but any such amount shall be carried forward and an adjustment with respect
thereto shall be made at the time of and together with any subsequent adjustment
which, together with such amount and any other amount or amounts so carried
forward, shall aggregate $.05 or more. In case ~e Company shall at any time
issue shares of Common Stock in any transaction described in Section 3. l(a)(iv)
or 3. 1(a)(v), such amount of $.05 per share (as theretofore increased or
decreased, if such amount shall have been adjusted in accordance with the
provisions of this Section 3. 1(a)(vii)) shall forthwith be proportionately
increased in the case of a transaction described in Section 3. 1(a)(v) or
decreased in the case of a transaction described in Section 3. 1(a)(iv) so as
appropriately to reflect such transaction.

      (viii) TIMING OF ISSUANCE OF ADDITIONAL COMMON STOCK UPON CERTAIN
ADJUSTMENTS. In any case in which the provisions of this Section 3.1(a) shall
require that an adjustment shall become effective immediately after a record
date for an event, the Company may defer until the occurrence of such event
issuing to the holder of this Warrant after such record date and before the
occurrence of such event the additional shares of Common Stock or other property
issuable or deliverable upon exercise by reason of the adjustment required by
such event over and above the shares of Common Stock or other property issuable
or deliverable upon such exercise before giving effect to such adjustment;
PROVIDED, HOWEVER, that the Company upon request shall deliver to such holder a
due bill or other appropriate instrument evidencing such holder's right to
receive such additional shares or other property, and such cash, upon the
occurrence of the event requiring such adjustment.

      (b) CURRENT MARKET PRICE. The Current Market Price shall mean, as of any
date, 10 % of the sum of the average, for each of the 10 consecutive Trading
Days immediately prior to such date, of either: (i) the high and low sales
prices of the Common Stock on such Trading Day as reported on the composite tape
for the principal national securities exchange on which the Common Stock may
then be listed, or (ii) if the Common Stock shall not be so listed on any such

                                       10                    

Trading Day, the high and low sales prices of Common Stock in the
over-the-counter market as reported by the Nasdaq Stock Market ("Nasdaq") for
National Market Issues, or (iii) if the Common Shares shall not be included in
the Nasdaq National Market on any such Trading Day, the representative bid and
asked prices at the end of such Trading Day in such market as reported by
Nasdaq, or 1(iv) if there be no such representative prices reported by Nasdaq,
the lowest bid and highest asked prices at the end of such Trading Day in the
over-the-counter market as reported by the National Quotation Bureau, Inc., or
any successor organization. For purposes of determining Current Market Price,
the term 'tTrading Day" shall mean a day on which an amount greater than zero
can be calculated with respect to the Common Stock under any one or more of the
foregoing categories (i), (ii), (iii) and (iv), and the "end" thereof, for the
purposes of categories (iii) and (iv), shall mean the exact time at which
trading shall end on the New York Stock Exchange. If the Current Market Price
cannot be determined under any of the foregoing methods, Current Market Price
shall mean the fair value per share of Common Stock on such date determined by
the Board of Directors in good faith, irrespective of any accounting treatment,
upon a review of relevant factors.

      (c) STATEMENT REGARDING ADJUSTMENTS. Whenever the Exercise Price shall be
adjusted as provided in Section 3.1(a), and upon each change in the number of
shares ~f the Common Stock issuable upon exercise of this Warrant, the Company
shall forthwith file, at the office of any transfer agent for this Warrant and
at the principal office of the Company, a statement showing in detail the facts
requiring such adjustment and the Exercise Price and new number of shares
issuable that shall be in effect after such adjustment, and the Company shall
also cause a copy of such statement to be given to the holder of this Warrant.
Each such statement shall be signed by the Company's chief financial or
accounting officer. Where appropriate, such copy may be given in advance and may
be included as part of a notice required to be mailed under the provisions of
Section 3.1(d).

      (d) NOTICE TO HOLDERS. In the event the Company shall propose to take any
action of the type described in clause (i) or (ii) (but only if the action of
the type described in such clause would result in an adjustment in the Exercise
Price), (iv), (v) or (vi) of Section 3.1(a), the Company shall give notice to
the holder of this Warrant, in the manner set forth in Section 6.6, which notice
shall specify the record date, if any, with respect to any such action and the
approximate date on which such action is to take place. Such notice shall also
set forth such facts with respect thereto as shall be reasonably necessary to
indicate the effect of such action (to the extent such effect may be known at
the date of such notice) on the Exercise Price and the number, kind or class of
shares or other securities or property which shall be deliverable upon exercise
of this Warrant. In the case of any action which would require the fixing of a
record date, such notice shall be given at least 10 days prior to the date so
fixed, and in case of all other action, such notice shall be given at least 15
days prior to the taking of such proposed action. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of any such
action.

      (e) TREASURV STOCK. For the purposes of this Section 3.1, the sale or
other disposition of any Common Stock of the Company theretofore held in its
treasury shall be deemed to be an issuance thereof.

                                         11

      3.2 COSTS. The Company shall pay all documentary, stamp, transfer or other
transactional taxes attributable to the issuance or delivery of shares of Common
Stock of the Company upon exercise of this Warrant; provided, HOWEVER, that the
Company shall not be required to pay any taxes which may be payable in respect
of any transfer involved in the issuance or delivery of any certificate for such
shares in a name other than that of the holder of this Warrant in respect of
which such shares are being issued.

      3.3 RESERVATIONS OF SHARES. The Company shall reserve at all times so long
as this Warrant remains outstanding, free from preemptive rights, out of its
treasury Common Stock or its authorized but unissued shares of Common Stock, or
both, solely for the purpose of effecting the exercise of this Warrant,
sufficient shares of Common Stock to provide for the exercise hereof.

      3.4 VALID ISSUANCE. All shares of Common Stock which may be issued upon
exercise of this Warrant will upon issuance by the Company be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issuance thereof attributable to any act or omission by the
Company, and the Company shall take no action which will cause a contrary result
(including without limitation, any action which would cause the Exercise Price
to be less than the par value, if any, of the Common Stock). ~
