THE SECURITIES EVIDENCED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES ONLY
AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
SECURITIES MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR HYPOTHECATED

                       LONG DISTANCE INTERNATIONAL INC.,

                             A FLORIDA CORPORATION

                              WARRANT CERTIFICATE

              Class B Bridge Loan Warrant to Purchase Common Stock

         Long Distance International Inc., a Florida Corporation (the
"Company"), hereby certifies that, for value received, Frederick A. DeLuca, an
individual residing at 512 NE 23rd Avenue, Ft. Lauderdale, Florida 33301 (the
"Holder"), is entitled to purchase from the Company [number]1 of fully paid,
validly issued and non-assessable shares of common stock, par value $0.001 per
share, of the Company ("Common Stock") at an exercise price of $0.001 per share
(the "Exercise Price") at any time or from time to time from and after the
Initial Exercise Date up to and including July 20, 2004. This Warrant shall
automatically become null and void and of no further force and effect in the
event the loans outstanding under the Term Loan Agreement dated as of the date
hereof (the "Loan Agreement"), among the Holder, LDI Acquisition Sub Inc., Long
Distance International Inc., the lenders party thereto (the "Lenders"), and
Frederick A. DeLuca, as collateral agent for the Lenders, are repaid in full on
or prior to November 20, 1999 (the "Early Payment Date"). In the event of such
repayment, the Holder shall deliver this Warrant Certificate to the Company
marked "void".

         This Warrant is one of a series of warrants designated the Class B
Bridge Loan Warrants to Purchase Common Stock ("Class B Warrants") and has been
issued with a companion warrant in a series designated the Class A Bridge Loan
Warrants to Purchase Common Stock ("Class A Warrants"). The Class B

------------

         1 This number ("ws") will be determined in accordance with the
following formula:
                       (   P  )
                  WS = ( -----) (OS)-A
                       (  1-P )

                  p = the product of (a) 0.50, multiplied by (b) the quotient
         of the amount of the Term Loan made by the Holder divided by $40
         million,

                  os = 87,805,999, the number of outstanding shares of the
         Company on a fully diluted basis immediately prior to the initial
         closing under the Term Loan Agreement.

                  A = The number of shares subject to the Class A Warrant
         issued as a companion to this Class B Warrant.



<PAGE>   2

Warrants and the Class A Warrants are being issued to the initial holders
thereof pursuant to the Loan Agreement, as additional consideration for, and as
an inducement to make, the Term Loans (as defined in the Loan Agreement). The
number of shares of Common Stock to be received upon the exercise of this
Warrant may be adjusted from time to time as provided herein.


         Section 1. Exercise of Warrant. Subject to the second sentence of the
introductory paragraph of this Warrant, this Warrant may be exercised in whole
or in part at any time or from time to time on or after the Initial Exercise
Date of this Warrant; provided, however, that if the day of exercise is a day
on which banking institutions in the State of Florida are authorized by law to
close, then the exercise by the Holder shall be deemed to take place on the
next succeeding day that is not such a bank closing day. The Initial Exercise
Date shall, subject to the second sentence of the introductory paragraph of
this Warrant, mean the date on which the first to occur of the following events
has occurred: (a) the sixteenth month anniversary date of the original issuance
of this Warrant Certificate; (b) the date the Company consummates an initial
public offering of shares of Common Stock pursuant to an effective registration
statement under the Securities Act of 1933; (c) the date the Company
consummates a sale of all or a substantial portion of the business of the
Company and its consolidated subsidiaries taken as a whole, whether by way of
merger, consolidation, sale of assets or sale of capital stock; (d) the date a
bankruptcy petition is filed by or against the Company, LDI Acquisition Sub
Inc. or a material operating subsidiary of LDI Acquisition Sub Inc.; (e) the
effective date of a waiver under the Indenture, dated as of April 13, 1998 (the
"Indenture"), pursuant to which the Company's 12 1/4% Senior Notes Due 2008
were issued, the effect of which waiver would be to waive the requirement that
the Company repurchase the Notes pursuant to Section 4.12 of the Indenture
because of a Change of Control (as defined in the Indenture); (f) the date on
which the exercise of all Class A Warrants and all Class B Warrants would not
result in a Change of Control; (g) the date on which a Change of Control under
the Indenture occurs for a reason other than an exercise of any of the Class A
Warrants or Class B Warrants issued under the Term Loan Agreement and a waiver
with respect thereto described in clause (e) above is not obtained; and (h) the
date on which Clifford Friedland and David Glassman cease to be directors of
the Company (other than by reason of their death or disability) or beneficially
own in the aggregate less than 5,000,000 shares of the Common Stock; provided,
that, notwithstanding the foregoing, in no event shall the Initial Exercise
Date be earlier than the Early Payment Date. This Warrant shall be exercised by
presentation and surrender of this Warrant to the Company at its principal
office, with the Exercise Form annexed hereto as Exhibit A duly executed by the
Holder, accompanied by payment in full of an amount equal to the product of the
number of shares of Common Stock being purchased by the Holder hereunder and
one-tenth of one cent ($0.001). Payment for such shares shall be made to the
Company in U.S. dollars in cash, by wire transfer or by certified or official
bank check payable to the order of the Company. Promptly after each such
exercise of this Warrant, the Company shall issue and deliver to the Holder a
certificate or certificates for the Common Stock issuable upon such exercise,
registered in the name of the Holder. If this Warrant should be exercised in
part only, the Company shall, upon surrender of this Warrant for cancellation,
promptly execute and deliver a new Warrant, in substantially the form of this
Warrant, evidencing the rights of the Holder thereof to purchase the balance of
the Common Stock purchasable hereunder. Upon the last to occur of receipt by
the Company of this Warrant at its office in proper form for exercise, together
with a duly executed Exercise Form, and receipt by the Company of full payment
of the exercise price for the shares of Common Stock then being purchased


                                       2
<PAGE>   3

hereunder, in accordance with the terms hereof, (i) the Holder shall be deemed
to be the holder of record of the shares of Common Stock issuable upon such
exercise, notwithstanding that the stock transfer books of the Company shall
then be closed or that certificates representing such shares of Common Stock
shall not then be physically delivered to the Holder, and (ii) such shares of
Common Stock shall be fully paid and non-assessable and free from all
preemptive rights of any shareholder and all taxes, liens and charges, with
respect to the issue thereof. The Company shall pay any stamp or issue taxes
payable in connection with issuance of Common Stock under this Warrant.

         Section 2. Fractional Shares. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. With respect to any fraction of a share called for upon any exercise
hereof, the Company shall pay to the Holder an amount in cash (rounded to the
nearest cent) equal to such fraction multiplied by one-tenth of one cent
($0.001) provided such amount is no less than one cent.

         Section 3. Loss of Warrant. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant (including any reasonable written certification that the Company may
require), and (in the case of loss, theft or destruction) of an agreement
indemnifying the Company in a form reasonably satisfactory to it, and (in the
case of mutilation) upon surrender and cancellation of this Warrant, the
Company shall execute and deliver to the Holder a new Warrant of like terms and
date.

         Section 4. Rights of the Holder. This Warrant shall not entitle the
Holder hereof to any voting or other rights of a shareholder of the Company,
either at law or in equity, or to any notice of meetings of shareholders or of
any other proceedings of the Company, except as provided in this Warrant, and
except in connection with Common Stock that the Holder purchases as provided
herein. No provision of this Warrant, in the absence of the purchase by the
Holder of Common Stock hereunder, shall give rise to any liability of such
Holder for the exercise price or as a shareholder of the Company, whether to
the Company or creditors of the Company. The shares of Common Stock issued upon
exercise of this Warrant shall be subject to a stop transfer order and the
certificate or certificates evidencing such shares shall bear the following
legend:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN REGISTERED UNDER
         THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), PURSUANT TO A
         REGISTRATION STATEMENT FILED WITH THE SECURITIES AND EXCHANGE
         COMMISSION. HOWEVER, SUCH SHARES MAY NOT BE OFFERED OR SOLD EXCEPT
         PURSUANT TO (i) A POST-EFFECTIVE AMENDMENT TO SUCH REGISTRATION
         STATEMENT, (ii) A SEPARATE REGISTRATION STATEMENT UNDER SUCH ACT, OR
         (iii) AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

and shall bear all legends as required pursuant to the other agreements to
which such Holder and the Company are a party. Any holder of any such
certificate or instrument bearing the foregoing legend shall be entitled to




                                       3
<PAGE>   4

promptly receive from the Company, without expense, a new certificate or
instrument of identical tenor representing the same kind of securities and the
same number or other amount thereof not bearing such legend if such securities
shall have been effectively registered under the Act and are sold or otherwise
disposed of in accordance with the intended method of disposition by the seller
thereof set forth in the registration statement, or such securities may be
freely transferred by such holder by reason of an exemption from registration
under the Act, or such legend otherwise is not required in order to ensure
compliance with the Act. The opinion of Loeb & Loeb LLP or other legal counsel
selected by such holder and reasonably satisfactory to the Company with respect
to any of the foregoing or with respect to any question concerning whether any
proposed transfer of any shares of common stock would violate the Act, shall be
sufficient to determine the issue.

         Section 5. Adjustments.

         (a) Adjustment of Price and Number of Common Stock. The initial
Exercise Calculation Price per share shall be one-tenth of one cent ($0.001).
The Exercise Calculation Price shall be subject to adjustment from time to time
as provided in Section 5(b), (c) and (h). Upon each adjustment, the Holder
shall thereafter be entitled to purchase, at one-tenth of one cent ($0.001),
the number of shares of Common Stock obtained by multiplying the Exercise
Calculation Price in effect immediately prior to such adjustment by the number
of shares of Common Stock issuable upon exercise of this Warrant immediately
prior to such adjustment, and dividing the product thereof by the Exercise
Calculation Price resulting from such adjustment.

         (b) Adjustment for Stock Splits and Combinations. If the Company at
any time or from time to time after the date of this Warrant (the "Commitment
Date") effects a subdivision of the outstanding Common Stock of the Company,
the Exercise Calculation Price then in effect immediately before that
subdivision shall be proportionately decreased; and conversely, if the Company
at any time or from time to time after the Commitment Date combines the
outstanding shares of Common Stock into a smaller number of shares, the
Exercise Calculation Price then in effect immediately before the combination
shall be proportionately increased. Any adjustment under this subsection (b)
shall become effective at the close of business on the date the subdivision or
combination becomes effective.

         (c) Adjustments for Certain Dividends and Distributions. If the
Company at any time after the Commitment Date makes, or fixes a record date for
the determination of holders of Common Stock entitled to receive, a dividend or
other distribution payable in additional shares of Common Stock, then and in
each such event the Exercise Calculation Price then in effect shall be
decreased as of the time of such issuance or, in the event such record date is
fixed, as of the close of business on such record date, by multiplying the
Exercise Calculation Price then in effect by a fraction (1) the numerator of
which is the total number of shares of Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such
record date, and (2) the denominator of which shall be the total number of
shares of Common Stock issued and outstanding immediately prior to the time of
such issuance or the close of business on such record date plus the number of
shares of Common Stock issuable in payment of such dividend or distribution.

         (d) Adjustments for other Dividends and Distributions. In the event
the Company at any time after the Commitment Date makes, or fixes a record date
for the determination of holders of Common Stock entitled to receive a dividend




                                       4
<PAGE>   5

or other distribution payable in securities (including options or warrants for
Common Stock) of the Company other than shares of Common Stock, then and in
each such event provision shall be made by the Company so that the Holder of
this Warrant shall receive upon exercise thereof, in addition to the number of
shares of Common Stock receivable thereupon, the amount of securities of the
Company which the Holder would have received had this Warrant been exercised to
purchase Common Stock immediately before the time of such issuance or the close
of business on such record date and had the Holder thereafter, during the
period from the date of such event to and including the exercise date, retained
such securities receivable by the Holder as aforesaid during such period,
subject to all other adjustments called for during such period under this
Section 5 with respect to the rights of the Holder, and subject to further
adjustment as provided herein.

         (e) Adjustments for the Reclassification, Exchange and Substitution.
In the event that at any time or from time to time after the Commitment Date,
the Common Stock issuable upon the exercise of this Warrant is changed into the
same or a different number of shares of any class or classes of stock, whether
by recapitalization, reclassification or otherwise (other than a subdivision or
combination of shares or stock dividend or a reorganization, merger,
consolidation or sale of assets, provided for elsewhere in this Section 5),
then and in any such event the Holder of this Warrant shall have the right
thereafter to exercise this Warrant and receive the kind and amount of stock
and other securities and property receivable, upon such recapitalization,
reclassification or other change, which the Holder would have received had this
Warrant been exercised to purchase Common Stock immediately before the time of
such recapitalization, reclassification or change, and had the Holder
thereafter, during the period from the date of such event to and including the
exercise date, retained such securities receivable by the Holder as aforesaid
during such period, subject to all other adjustments called for during such
period under this Section 5 with respect to the rights of the Holder, and
subject to further adjustment as provided herein. In any such case, appropriate
adjustment shall be made in the application of the provisions of this Section 5
with respect to the rights of the Holder hereof after the reorganization,
merger, consolidation or sale to the end that the provision of this Section 5
(including adjustment of the Exercise Calculation Price then in effect and the
number of shares purchasable upon exercise hereof) shall be applicable after
that event and be as nearly equivalent as may be practicable.

         (f) Reorganizations, Mergers, Consolidations or Sales of Assets. If at
any time or from time to time after the Commitment Date there is a capital
reorganization of the Common Stock (other than a recapitalization, subdivision,
combination, reclassification or exchange of shares provided for elsewhere in
this Section 5) or a merger or consolidation of the Company with or into
another entity, or the sale of all or substantially all of the Company's
properties and assets to any other person or entity, then as part of such
reorganization, merger, consolidation or sale, provision shall be made so that
the Holder of this Warrant shall thereafter be entitled to receive upon
exercise of the Warrant the number of shares of stock or other securities or
property which the Holder would have received had this Warrant been exercised
to purchase Common Stock immediately before the time of such capital
reorganization, merger, consolidation or sale, and had the Holder thereafter,
during the period from the date of such event to and including the exercise
date, retained such securities receivable by the Holder as aforesaid during
such period, subject to all other adjustments called for during such period




                                       5
<PAGE>   6

under this Section 5 with respect to the rights of the Holder, and subject to
further adjustment as provided herein. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 5 with
respect to the rights of the Holder hereof after the reorganization, merger,
consolidation or sale to the end that the provision of this Section 5
(including adjustment of the Exercise Calculation Price then in effect and the
number of shares purchasable upon exercise hereof) shall be applicable after
that event and be as nearly equivalent as may be practicable.

         (g) Other Adjustments of Exercise Price and Number of Warrant Shares.

                  (i) In case the Company shall, at any time after the date
hereof and in connection with an equity investment in or a loan to the Company
and/or LDI Acquisition Sub Inc., (a "Subsequent Financing") issue or sell any
shares of Common Stock and/or any options, rights or warrants to subscribe for
shares of Common Stock ("New Shares"), then the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased in accordance
with, and subject to, the following provisions:

                           (A) The number of additional shares of Common Stock
issuable upon exercise of this Warrant shall be determined in accordance with
the following formula:


X   =     (WS) (NS)
          ---------
          OS

X   =     The number of additional shares of Common Stock issuable upon
          exercise of this Warrant

WS  =     The number of shares of Common Stock issuable upon exercise of this
          Warrant immediately prior to the issuance or sale of New Shares.

NS  =     The number of shares of Common Stock issued or sold giving rise to
          the adjustment pursuant to this Section 5(g) , and/or the maximum
          number of Shares of Common Stock issuable upon exercise, conversion
          or exchange of the Rights issued or sold giving rise to the
          adjustment pursuant to this Section 5(g).

OS =      87,805,999

                           (B) Upon the expiration of any rights, options,
warrants or convertible or exchangeable securities for which an adjustment was
made hereunder, if any thereof shall not have been exercised, the number of
shares of Common Stock purchasable upon the exercise of each Warrant shall,
upon such expiration, be readjusted and shall thereafter be such as it would
have been had it been originally adjusted (or had the original adjustment not
been required, as the case may be) as if (i) the only rights, options, warrants
or convertible or exchangeable securities so issued were the rights, options,
warrants or convertible or exchangeable securities, if any, actually exercised,
converted or exchanged and (ii) such rights, options, warrants or convertible
or exchangeable securities, if any, were exercised, converted or exchanged for
the consideration actually received by the Company upon such exercise,




                                       6
<PAGE>   7

conversion or exchange plus the aggregate consideration, if any, actually
received by the Company for the issuance, sale or grant of all such rights,
options, warrants or convertible or exchangeable securities whether or not
exercised, converted or exchanged.

                           (C) Except as set forth below, "New Shares" shall
mean any shares of Common Stock or Rights issued or sold or proposed to be
issued or sold by the Company on or after the initial issue date (the "Initial
Issue Date") of the initial Class A Warrants and Class B Warrants under the
Term Loan Agreement. "New Shares" does not include (i) the Class A Warrants and
the Class B Warrants issued and sold by the Company or any shares of Common
Stock issued upon exercise of any thereof, (ii) shares of Common Stock or
Rights issued in consideration of the acquisition of all or any portion of a
business as a going concern, whether such acquisition shall be effected by a
purchase of assets, exchange of securities, merger, consolidation,
reorganization or otherwise, (iii) shares of Common Stock or Rights offered or
proposed to be offered to the public pursuant to a registration statement filed
under the Securities Act of 1933, as amended, or to any underwriter of any such
offering, (iv) shares of Common Stock or Rights issued in connection with any
stock split or stock dividend by the Company, (v) shares of Common Stock or
Rights which the Company and the holders of at least 50% of the issued and
outstanding shares issuable upon exercise of the Class B Warrants agree in
writing at any time and from time to time should not be subject to the
provisions of this Section 5(g); (vi) stock options granted to the Company's
directors, officers, employees, consultants and independent contractors
pursuant to bona fide stock option or employee benefit plans of the Company
approved by a majority of either the Board of Directors of the Company or
committee of the Board of Directors of the Company delegated to perform such
function, or shares of Common Stock issued upon exercise thereof, (vii) shares
of Common Stock issued upon exercise of Rights outstanding on the Initial Issue
Date, or (viii) shares of Common Stock issued upon exercise, exchange or
conversion of any Rights referred to in any preceding clause of this sentence.
No adjustment in the number of shares of Common Stock issuable or issued upon
exercise, exchange or conversion of any of the Rights referred to in the
immediately preceding sentence by reason of original provisions thereof which
provide for an automatic adjustment upon the occurrence of specified events
shall be deemed to be an issuance or proposed issuance of New Shares. For the
purposes of the definition of "New Shares", the term "Rights" shall mean any
options, warrants, convertible or exchangeable securities or other rights,
however denominated, to subscribe for, purchase or otherwise acquire Common
Stock or other Rights to subscribe for purchase or otherwise acquire Common
Stock, with or without payment of additional consideration in cash or property,
either immediately or upon the occurrence of a specified date or a specified
event or the satisfaction or happening of any other condition or contingency.

                  (ii) The adjustments provided for in this Section 5(g) shall
be made for all Subsequent Financings to the extent the aggregate gross
proceeds thereof do not exceed the difference of $40,000,000 less the aggregate
amount of Term Loans made by the Holder on the date of original issuance and by
all other holders of Class A Warrants and Class B Warrants on or prior to such
date.

         (h) Accountants' Certificate of Adjustment. In each case of an
adjustment or readjustment of the Exercise Calculation Price or the number of
shares of Common Stock or other securities issuable upon exercise of this
Warrant, the Company, at its expense, reasonably promptly after such adjustment
or readjustment, shall cause independent public accountants of recognized




                                       7
<PAGE>   8

standing selected by the Company (who may be the independent public accountants
then auditing the books of the Company) to compute such adjustment or
readjustment in accordance with the provisions hereof and to prepare a
statement showing such adjustment or readjustment, and shall mail such
statement, by first class mail, postage prepaid, to the Holder of this Warrant
at the Holder's address as shown in the Company's books and records. The
statement shall set forth such adjustment or readjustment, showing in detail
the facts upon which such adjustment or readjustment is based.

         Section 6. Reservation and Issuance of Common Stock

         The Company shall at all times have authorized, and reserve and keep
available, free from preemptive rights, for the purpose of enabling it to
satisfy any obligation to issue fully paid and non-assessable shares of Common
Stock upon the exercise of this Warrant, the number of shares of Common Stock
deliverable upon exercise of this Warrant, and the shares of Common Stock
issued upon exercise of this Warrant and full payment therefor in accordance
with the provisions hereof shall be validly issued, fully paid, non-assessable
and free of preemptive rights.

         Section 7. Delivery of Stock Certificates on Exercise. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within ten days thereafter, 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 holder hereof, or as such holder (upon payment by
such holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock (or Other Securities) to which such holder shall be entitled on such
exercise, plus, in lieu of any fractional share to which such holder would
otherwise be entitled, cash equal to such fraction multiplied by the then
current market value of one full share, together with any other stock or other
securities and property (including cash, where applicable) to which such holder
is entitled upon such exercise pursuant to Section 1 or otherwise under the
terms of this Warrant.

         Section 8. No Impairment. The Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, acquisition,
business combination, transfer of assets, consolidation, merger, dissolution,
issue or sale of securities or any other voluntary 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 action as may be necessary or appropriate in
order to protect the rights of the holder of this Warrant. Without limiting the
generality of the foregoing, the Company:

         (a) will not increase the par value of any shares of stock receivable
on the exercise of this Warrant above the amount payable therefor on such
exercise; and

         (b) will take all such action as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock on the exercise of this Warrant from time
to time outstanding.

         Section 9. Other Notices. In case at any time:

         (a) The Company shall declare any cash dividend on its Common Stock;




                                       8
<PAGE>   9

         (b) The Company shall pay any dividend payable in capital stock upon
its Common Stock or make any distribution (other than regular cash dividends)
to the holders of its Common Stock;

         (c) The Company shall authorize the distribution to all holders of its
Common Stock of evidences of its indebtedness or assets (other than cash
dividends or cash distributions payable out of earnings or earned surplus or
dividends payable in Common Stock);

         (d) There shall be any capital reorganization, or reclassification of
the capital stock of the Company, or consolidation or merger of the Company
with another entity (other than a subsidiary of the Company in which the
Company is the surviving or continuing corporation and no change occurs in the
Company's Common Stock), or sale of all or substantially all of its assets to,
another person or entity;

         (e) There shall be a voluntary or involuntary dissolution,
liquidation, bankruptcy, assignment for the benefit of creditors, or winding up
of the Company; or

         (f) The Company proposes to take any other action or an event occurs
which would require an adjustment pursuant to Section 5;

then, in any one or more of said cases, the Company shall give written notice,
addressed to the Holder at the address of such Holder as shown on the books of
the Company within three business days thereafter.

         Section 10. Governing Law and Jurisdiction. This Warrant shall be
governed by and interpreted under the law of the State of New York applicable
to contracts negotiated, entered into and to be performed solely in that State,
without regard to the choice or conflicts of law principles of such State.

         Section 11. Severability. If any part of this Warrant is held to be
unenforceable or invalid under, or in conflict with, the applicable law of any
jurisdiction, then the unenforceable, invalid or conflicting part shall be
narrowed or replaced, to the extent possible, with a construction in such
jurisdiction that effectuates the intent of the parties regarding this Warrant
and the unenforceable, invalid or conflicting part. Notwithstanding the
unenforceability, invalidity or conflict with applicable law of any part of
this Warrant, the remaining parts shall be valid, enforceable and binding on
the parties.

         Section 12. Binding Effect. This Warrant shall be binding upon,
enforceable by and shall inure to the benefit of the parties hereto and their
respective permitted successors or assignees. Any Holder and its permitted
successors and assignees shall be deemed to be a Holder as defined and provided
for in this Warrant.

         Section 13. Register; Assignment. The Holder may assign or transfer
all or any portion of this Warrant in compliance with the terms hereof. Any
Warrants issued upon the transfer or exercise in part of this Warrant shall be
numbered and shall be registered in a Warrant Register as they are issued. The
Company shall be entitled to treat the registered holder of any Warrant on the
Warrant Register as the owner in fact thereof for all purposes and shall not be
bound to recognize any equitable or other claim to or interest in such Warrant

on the part of any other person, and shall not be liable by reason of any
registration or transfer of Warrants which 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 or transfer, or with the knowledge of such facts
that its participation therein amounts to bad faith. This Warrant shall be
transferable only on the books of the Company upon delivery thereof duly
endorsed by the Holder or by its duly authorized attorney or representative, or
accompanied by proper evidence of succession, assignment, or authority to
transfer. In all cases of transfer by an attorney, executor, administrator,
guardian, or other legal representative, duly authenticated evidence of his or
its authority shall be produced. Upon any registration of transfer, the Company
shall deliver a new Warrant or Warrants to the person entitled thereto. This
Warrant may be exchanged, at the option of the Holder thereof, for another
Warrant, or other Warrants of different denominations, of like tenor and
representing in the aggregate the right to purchase a like number of Warrants
(or portions thereof), upon surrender to the Company or its duly authorized
agent. Notwithstanding the foregoing, the Company shall have no obligation to
cause Warrants to be transferred on its books to any person unless it receives
an opinion from counsel reasonably satisfactory to it that such transfer
complies with the provisions of the Act, and the rules and regulations
thereunder.

         Section 14. Amendment; Waiver. This Warrant may be amended only by a
writing signed by the parties hereto. Neither any failure nor any delay on the
part of any party to this Warrant in exercising any right, power or privilege
hereunder shall operate as a waiver of any rights of any such party, unless
such waiver is made by a writing executed by such party and delivered to the
other party, nor shall a single or partial exercise of any right preclude any
other or further exercise of any other right, power or privilege accorded to
any party to this Warrant.
