            exercise form attached hereto duly executed) at the principal office

<PAGE>

            date of such exercise multiplied by the number of shares of Warrant
            Stock with respect to which this Warrant is then being exercised,
            payable at the Holder's election in cash by certified or official
            bank check or wire transfer.

      (c)   Issuance of Stock Certificates. In the event of any exercise of the
            rights represented by this Warrant in accordance with and subject to
            the terms and conditions hereof, (i) certificates for the shares of

            and delivered to the Holder hereof within a reasonable time, not
            exceeding five Trading Days after such exercise, and the Holder
            hereof shall be deemed for all purposes to be the Holder of the

            representing the number of shares of Warrant Stock, if any, with
            respect to which this Warrant shall not then have been exercised
            (less any amount thereof which shall have been canceled in payment
            or partial payment of the Warrant Price as hereinabove provided)
            shall also be issued to the Holder hereof at the Issuer's expense
            within such time.

      (d)   Transferability of Warrant. Subject to the provisions of subsection
            (e) of this Section 2, this Warrant may be transferred by the Holder
            without the consent of the Issuer. If transferred pursuant to this
            paragraph, and subject to the provisions of subsection (e) of this

            attorney, upon surrender of this Warrant at the principal office of
            the Issuer, properly endorsed (by the Holder executing an assignment
            in the form attached hereto) and upon payment of any necessary
            transfer tax or other governmental charge imposed upon such
            transfer. This Warrant is exchangeable at the principal office of
            the Issuer for Warrants for the purchase of the same aggregate
            number of shares of Warrant Stock, each new Warrant to represent the
            right to purchase such number of shares of Warrant Stock as the
            Holder hereof shall designate at the time of such exchange. All
            Warrants issued on transfers or exchanges shall be dated the
            Original Issue Date and shall be identical with this Warrant except
            as to the number of shares of Warrant Stock issuable pursuant
            hereto.

      (e)   Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
that this Warrant and the shares of Warrant Stock to be issued upon exercise
hereof are being acquired solely for the Holder's own account and not as a
nominee for any other party, and for investment, and that the Holder will not
offer, sell, transfer or otherwise dispose of this Warrant or any shares of
Warrant Stock to be issued upon exercise hereof except pursuant to an effective
registration statement, or an exemption from registration, under the Securities
Act and any applicable state securities laws.

            (ii) Except as provided in paragraph (iii) below, this Warrant and
all certificates representing shares of Warrant Stock issued upon exercise
hereof shall be stamped or imprinted with a legend in substantially the
following form:

            THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE
HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,
TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT
AND UNDER APPLICABLE STATE SECURITIES LAWS OR TTR TECHNOLOGIES, INC. SHALL HAVE
RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT

                                       2
<PAGE>

REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE
PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

            (iii) The restrictions imposed by this subsection (e) upon the
transfer of this Warrant and the shares of Warrant Stock to be purchased upon
exercise hereof shall terminate (A) when such securities shall have been
effectively registered under the Securities Act, (B) upon the Issuer's receipt
of an opinion of counsel, in form and substance reasonably satisfactory to the
Issuer, addressed to the Issuer to the effect that such restrictions are no
longer required to ensure compliance with the Securities Act or (C) upon the
Issuer's receipt of other evidence reasonably satisfactory to the Issuer that
such registration is not required. Whenever such restrictions shall cease and
terminate as to any such securities, the Holder thereof shall be entitled to
receive from the Issuer (or its transfer agent and registrar), without expense
(other than applicable transfer taxes, if any), new Warrants (or, in the case of
shares of Warrant Stock, new stock certificates) of like tenor not bearing the
applicable legends required by paragraph (ii) above relating to the Securities
Act and state securities laws.

      3. Stock Fully Paid: Reservation and Listing of Shares: Covenants.

      (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through Issuer. The Issuer further covenants and agrees
that during the period within which this Warrant may be exercised, the Issuer
will at all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a number of shares of Common Stock equal to at least
100% of the aggregate number of shares of Warrant Stock issuable upon the
exercise of the Warrant.

      (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

      (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate of Incorporation or by-laws of the
Issuer in any manner that would adversely affect in any way the powers,
preferences or relative participating, optional or other special rights of the
Common Stock or which would adversely affect the rights of the Holder of this
Warrant, (iii) take all such action as may be reasonably necessary in order that
the Issuer

                                       3
<PAGE>

may validly and legally issue fully paid and nonassessable shares of Common
Stock, free and clear of any liens, claims, encumbrances and restrictions (other
than as provided herein) upon the exercise of this Warrant, and (iv) use its
best efforts to obtain all such authorizations, exemptions or consents from any
public regulatory body having jurisdiction thereof as may be reasonably
necessary to enable the Issuer to perform its obligations under this Warrant.

      (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

      4. Registration Rights Under The Securities Act

            The Holder shall have the registration rights granted to the Holder
in the Registration Rights Agreement of even date hereof between the Holder and
the Company.

      5. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

      (a)   Recapitalization, Reorganization, Reclassification, Consolidation,
            Merger or Sale.

            (i) In case the Issuer after the Original Issue Date shall do any of
      the following (each, a "Triggering Event"): (a) consolidate with or merge
      into any other Person and the Issuer shall not be the continuing or
      surviving corporation of such consolidation or merger; provided, however,
      that a merger for the sole purpose of effecting a change in domicile of
      the Issuer from one state to another shall not be deemed a Triggering
      Event, or (b) permit any other Person to consolidate with or merge into
      the Issuer and the Issuer shall be the continuing or surviving Person but,
      in connection with such consolidation or merger, any Capital Stock of the
      Issuer shall be changed into or exchanged for Securities of any other
      Person or cash or any other property, or (c) transfer all or substantially
      all of its properties or assets to any other Person, or (d) effect a
      capital reorganization or reclassification of its Capital Stock, then, and
      in the case of each such Triggering Event, proper provision shall be made
      so that, upon the basis and the terms and in the manner provided in this
      Warrant, the Holder of this Warrant shall be entitled upon the exercise
      hereof at any time after the consummation of such Triggering Event, to the
      extent this Warrant is not exercised prior to such Triggering Event, or is
      redeemed in connection with such Triggering Event, to receive at the
      Warrant Price in effect at the time immediately prior to the consummation
      of such Triggering Event in lieu of the Common Stock issuable upon such
      exercise of this Warrant prior to such Triggering Event, the Securities,
      cash and property to which the Holder would have been entitled upon the
      consummation of such Triggering Event if the Holder had exercised the
      rights represented by this Warrant immediately prior thereto, subject to
      adjustments and increases (subsequent to such corporate action) as nearly
      equivalent as possible to the adjustments provided for in Section 4 hereof

      (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the

                                       4
<PAGE>

increase in the total number of shares of Common Stock outstanding as a result
of such subdivision, or (ii) in the case of a combination of shares, the Warrant
Price shall be proportionately increased (as at the effective date of such
combination or, if the Issuer shall take a record of holders of its Common Stock
for the purpose of so combining, as at the applicable record date, whichever is
earlier) to reflect the reduction in the total number of shares of Common Stock
outstanding as a result of such combination.

      (c) Issuance of Additional Shares of Common Stock. If at any time the
Company shall issue any Additional Shares of Common Stock at a price per share
which is lower than $5.56, then the number of shares of Common Stock to be
received by the holder of this Warrant upon the exercise hereof shall be
adjusted to that number determined by multiplying [(a) the number of shares of
Common Stock purchasable hereunder immediately prior thereto by (b) a fraction
(i) the numerator of which shall be the sum of (A) the number of shares of
Common Stock Deemed Outstanding immediately prior to the issuance of such shares
of Common Stock plus (B) the number of shares of Common Stock issued in the
subject transaction and (ii) the denominator of which shall be an amount equal
to the sum of (x) the number of shares of Common Stock Deemed Outstanding
immediately prior to the issuance of such shares of Common Stock plus (y) the
quotient of (1) the Offering Price multiplied by the number of shares of Common
Stock so issued by the Company, divided by (2) $5.56. The foregoing provisions
shall not apply to Additional Shares (A) if price per share (or in the case of
an option or warrant, the exercise price thereof) is not less than $5.00 and the
gross proceeds received or receivable by the Company as consideration for the
issue of such Additional Shares, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein designated to protect against dilution)
payable to the Company upon the exercise of such Additional Shares, equals or
exceeds $1,500,000 (B) (ii) any capital stock or other securities offered or
issued in connection with any acquisition of another corporation or entity by
the Company by merger or purchase of all, or substantially all, of the assets of
such corporation or entity, share exchange, reorganization or the like (C) any
capital stock or other securities issued in connection with any stock split,
stock dividend, recapitalization or the like by the Company.;

      (d) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

            (i) Common Stock Dividends. Pay a dividend in, or make any other
      distribution to its stockholders (without consideration therefor) of,
      shares of Common Stock, the Warrant Price shall be adjusted, as at the
      date the Issuer shall take a record of the holders the Issuer's Capital
      Stock for the purpose of receiving such dividend or other distribution (or
      if no such record is taken, as at the date of such payment or other
      distribution), to that price determined by multiplying the Warrant Price
      in effect immediately prior to such record date (or if no such record is
      taken, then immediately prior to such payment or other distribution), by a
      fraction (1) the numerator of which shall be the total number of shares of
      Common Stock outstanding immediately prior to such dividend or
      distribution, and (2) the denominator of which shall be the total number
      of shares of Common Stock outstanding immediately after such dividend or
      distribution (plus in the event that the Issuer paid cash for fractional
      shares, the number of additional shares which would have been outstanding
      had the Issuer issued fractional shares in connection with said
      dividends); or

            (ii) Other Dividends. Pay a dividend on, or make any distribution of
      its assets upon or with respect to (including, but not limited to, a
      distribution of its property as a dividend in liquidation or partial
      liquidation or by way of return of capital), the Common Stock (other than
      as described in clause (i) of this subsection (c)), or in the event that
      the Issuer shall offer options or rights to subscribe for shares of Common
      Stock, or issue any Common Stock Equivalents, to all of its holders of
      Common Stock, then on the record date for such payment, distribution or
      offer or, in the absence of a record date, on the date of such

                                       5
<PAGE>

      payment, distribution or offer, the Holder shall receive what the Holder
      would have received had it exercised this Warrant in full immediately
      prior to the record date of such payment, distribution or offer or, in the
      absence of a record date, immediately prior to the date of such payment,
      distribution or offer.

      (e) Other Provisions Applicable to Adjustments Under this Section 5. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4. The number of shares of Common
Stock at any time outstanding shall (A) not include any shares thereof then
directly or indirectly owned or held by or for the account of the Issuer or any
of its Subsidiaries, and (B) be deemed to include all shares of Common Stock
then issuable upon conversion, exercise or exchange of any then outstanding
Common Stock Equivalents or any other evidences of indebtedness, shares of
Capital Stock (including, without limitation, the Preferred Stock) or other
Securities which are or may be at any time convertible into or exchangeable for
shares of Common Stock or Other Common Stock.

      (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (d) of this
Section 5, inclusive, then the Warrant Price shall be adjusted in such manner
and at such time as the Board may in good faith determine to be equitable in the
circumstances.

      (g) Adjustment of Warrant Share Number. Upon each adjustment in the
Warrant Price pursuant to the provisions (b) and (c)(i) of this Section 5, the
Warrant Share Number shall be adjusted, to the nearest one hundredth of a whole
share, to the product obtained by multiplying the Warrant Share Number
immediately prior to such adjustment in the Warrant Price by a fraction, the
numerator of which shall be the Warrant Price immediately before giving effect
to such adjustment and the denominator of which shall be the Warrant Price
immediately after giving effect to such adjustment. If the Issuer shall be in
default under any provision contained in Section 3 of this Warrant so that
shares issued at the Warrant Price adjusted in accordance with this Section 4
would not be validly issued, the adjustment of the Warrant Share Number provided
for in the foregoing sentence shall nonetheless be made and the Holder of this
Warrant shall be entitled to purchase such greater number of shares at the
lowest price at which such shares may then be validly issued under applicable
law. Such exercise shall not constitute a waiver of any claim arising against
the Issuer by reason of its default under Section 3 of this Warrant.

      (h) Form of Warrant after Adjustments. The form of this Warrant need not
be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

      (i) Continuation of Terms. Upon any reorganization, consolidation, merger
or transfer (and any dissolution following any transfer) referred to in this
section 5, this Warrant shall continue in full force and effect and the terms
hereof shall be applicable to the shares of stock and other securities and
property receivable on the exercise of this Warrant after the consummation of
such reorganization, consolidation, or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer, the person acquiring all or substantially all of the
properties or assets of the Company, whether or not such person shall have
expressly assumed the terms of this Warrant.

      6. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 5 hereof (for purposes of this
Section 6, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a

                                       6
<PAGE>

certificate 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 made any
determination hereunder), and the Warrant Price and Warrant Share Number after
giving effect to such adjustment, and shall cause copies of such certificate to
be delivered to the Holder of this Warrant promptly after each adjustment. Any
dispute between the Issuer and the Holder of this Warrant with respect to the
matters set forth in such certificate may at the option of the Holder of this
Warrant be submitted to one of the national accounting firms currently known as
the "big five" mutually agreed upon by the Issuer and the Holder or, in the
event the Issuer and the Holder are unable to agree, a "big five" national
accounting firm (other than the Issuer's independent auditors) selected by the
Issuer's independent auditors. The firm selected in the manner as provided in
the preceding sentence shall be instructed to deliver a written opinion as to
such matters to the Issuer and the Holder within thirty days after submission to
it of such dispute. Such opinion shall be final and binding on the parties
hereto. The fees and expenses of such accounting firm shall be paid by the
Issuer.

      7. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

      8. Redemption of Warrants. The Company may redeem the Class A Warrants for
$.10 per warrant 6 months following issuance if the underlying common stock is
registered and the Company's common shares have traded at or above 200% of the
warrant exercise price (the "trigger price") for a period of twenty consecutive
trading days.

      9. Issuance of Class B Warrants. Upon exercise of the Class A Warrants,
the investors will be issued Class B warrants for such number of shares as shall
equal one half the number of shares for which this Class A warrants is exercised
with a term of 36 months and an exercise price of 120% of the Class A Warrant
trigger price. The Class B warrants may be redeemed by the Company if the
underlying common stock is registered and the common shares have traded at $26

and such certificate or

<PAGE>

certificates shall be deemed to have been issued and any person so designated to
be named therein shall be deemed to have become a holder of the such Shares as
of the close of business on the date of the surrender of the Warrant and payment
of the Per Share Warrant Price. If this warrant should be exercised in part
only, the Company shall, upon surrender of the Warrant for cancellation, execute
and deliver a new Warrant evidencing the rights of the Holder hereof to purchase
the balance of the Shares purchasable hereunder.

1.3 Any stamp tax attributable to the issuance of the Shares shall be borne
solely by Holder.

2. Representations and Warranties

2.1 The Holder (i) represents, warrants, covenants and agrees that the Warrant
and the underlying Warrant Shares are being acquired by the Holder for the
Holder's own account, for investment purposes only, and not with a view to or
for sale in connection with any distribution thereof or with any present
intention of selling or distributing all or any part of the Warrant or the
underlying Warrant Shares thereof; (ii) understands (x) that if it should
thereafter decide to dispose of such Warrant or Warrant Shares (which it does
not contemplate at such time) it may do so only in compliance with the
Securities Act, (y) this Warrant and the Warrant Shares are not registered under
the Securities Act nor does the Company have any obligation to register this
Warrant and the Warrant Shares (except as provided in paragraph 3 below) and (z)
that it is unlikely that Rule 144 adopted by the Securities and Exchange
Commission will be applicable to permit sales of this Warrant and the Warrant
Shares in reliance thereon; and (iii) acknowledges that, as of the date hereof,
it has been given a full opportunity to ask questions of and to receive answers
from the Company concerning this Warrant and the Warrant Shares and the business
of the Company and to obtain such information as it desired in order to evaluate
the acquisition of this Warrant and the Warrant Shares, and all questions have
been answered to its full satisfaction.

3. Reservation of Shares.

The Company has reserved, and shall at all times so long as any Warrant remains
outstanding, keep reserved, out of its authorized and unissued capital stock,
such number of shares of Common Stock, par value $0.001, as shall be subject to
purchase under the Warrant.

4. Mutilation or Loss of Warrant. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) receipt of reasonably
satisfactory indemnification, and (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant
of like tenor and date and any such lost, stolen, destroyed or mutilated Warrant
shall thereupon become void.

5. Rights of the Holder. The Holder shall not, by virtue hereof, be entitled to
any rights of a stockholder in the Company, either at law or equity, and the
rights of the Holder are limited to those expressed in this Warrant and are not
enforceable against the Company except to the extent set forth herein.

<PAGE>

6. Stock Dividends, Reclassifications, Reorganization, Anti-Dilution Provisions,
Etc.

6.1 In case prior to the expiration of this Warrant by exercise or by its terms
the Company shall issue any shares of its Common Stock as a stock dividend or
subdivide the number of outstanding shares of Common Stock into a greater number
of shares, then, in either of such cases, the Exercise Price per share of the
Warrant Shares purchasable pursuant to this Warrant in effect at the time of
such action shall be proportionately reduced and the number of Warrant Shares
purchasable at that time shall be proportionately increased; and, conversely, in
the event the Company shall contract the number of outstanding shares of Common
Stock by combining such shares into a smaller number of shares, then, in such
case, the Exercise Price per share of the Warrant Shares purchasable pursuant to
this Warrant shall be proportionately decreased. Any dividend paid or
distributed upon the Common Stock in stock of any other class of securities
convertible into shares of Common Stock shall be treated as a dividend paid in
Common Stock to the extent that shares of Common Stock are issuable upon
conversion thereof.

6.2 In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
surviving or the continuing corporation) or in the case of any sale or
conveyance to another corporation or other entity of the property, assets or
business of the Company as an entirety or substantially as an entirety, in any
such case, the Company or such successor or purchasing corporation or entity, as
the case may be, shall (i) execute with the Holder an agreement that the Holder
shall have the right thereafter to receive upon the exercise of the Warrant the
kind and amount of shares and/or other securities or other property which he
would have owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Warrant been exercised
immediately prior to such action, (ii) make effective provision in its
certificate of its incorporation or otherwise, if necessary, in order to effect
such agreement, and (iii) set aside or reserve for the benefit of the Holder,
the stock, securities, property and cash to which the Holder would be entitled
to upon exercise of this Warrant.

6.3 In case of any reclassification or change of the Warrant Shares issuable
upon exercise of this Warrant (other than a change in par value or from no par
value to a specific par value, or as a result of a subdivision or combination,
including any change in the shares into two or more classes or series of
shares), or in the case of any consolidation or merger of another corporation
into the Company in which the Company is the continuing corporation and in which
there is a reclassification or change (including a change in the right to
receive cash or other property) of the Shares (other than a change in the par
value, or from no par value to a specific par value or, as a result of a
subdivision or combination, including any change in the shares into two or more
classes or series of shares), Holder shall have the right thereafter to receive
upon exercise of this Warrant solely the kind and amount of shares of stock and
other securities, property, cash or combination thereof receivable upon such
reclassification, change, consolidation or merger by a holder of the number of
Shares for which this Warrant might have been exercised immediately prior to
such reclassification, change, consolidation or merger.

<PAGE>

6.4 Upon the occurrence of each event requiring an adjustment of the Exercise
Price and the number of Warrant Shares purchasable at such adjusted Exercise
Price by reason of such event in accordance with the provision of this Section
6, the Company shall compute the adjusted Exercise Price and the adjusted number
of Warrant Shares purchasable at such adjusted Exercise Price by reason of such
event in accordance with the provisions of this Section 6 and shall prepare a
certificate setting forth such adjusted Exercise Price and the adjusted number
of Warrant Shares and showing in reasonable detail the facts upon which such
determination is made. The Company shall mail to the holder of this Warrant a
copy of such Certificate, and thereafter said certificate shall be conclusive
and shall be binding upon such holder unless contested by such holder in a
written notice furnished to the Company within 15 days of the receipt thereof
setting forth in reasonable detail the basis of such contention.

6.5 In case:

(a) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend or any other distribution in
respect of the Common Stock (including cash), pursuant to without limitation,
any spin-off, split-off or distribution of the Company's assets; or

(b) the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to subscribe for or purchase any shares of stock of
any class or to receive any other rights; or

(c) of any classification, reclassification or other reorganization of the
capital stock of the Company, consolidation or merger of the Company with or
into another corporation, or conveyance of all or substantially all of the
assets of the Company; or

(d) of the voluntary or involuntary dissolution, liquidation or winding up of
the Company;

then, and in any such case, the Company shall mail to the Holder, at least
twenty (20) days prior thereto, a notice stating the date or expected date on
which a record is to be taken for the purpose of such dividend or distribution
of rights, or the date on which such classification, reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation, or
winding up is to take place, as the case may be. Such notice shall also specify
the date or expected date, if any is to be fixed, as of which holders of Common
Stock of record shall be entitled to participate in said dividend on
distribution of rights, or shall be entitled to exchange their shares of Common
stock for securities or other property deliverable upon such classification,
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation, or winding up, as the case may be. The failure to give
such notice shall not affect the validity of any such proceeding or transaction
and shall not affect the right of the holder of this Warrant to participate in
said dividend, distribution of rights, or any such exchange and acquire the kind
