               Warrant to Purchase 100,000 Shares of Common Stock



                   WARRANT TO PURCHASE SHARES OF COMMON STOCK

                                       OF

                            PICK COMMUNICATIONS CORP.


         This is to certify that, FOR VALUE RECEIVED, IDT Corporation ("Holder")
having an office at 190 Main Street, Hackensack, NJ 07601, is entitled to
purchase, subject to the provisions of this Warrant, from PICK COMMUNICATIONS
CORP., a Nevada corporation (the "Company"), 100,000 fully paid, validly issued
and non-assessable shares of Common Stock (the "Common Stock"), par value $.001
per share, of the Company at any time or from time to time for one year from the
date hereof at the price of the Company's stock at the close of business on the
date hereof. To the extent that there is no public market for the Company's
shares at the day this or any subsequent warrant is issued, the exercise price
shall be the fair market value of the Company's stock, as reasonably determined
by the Company's Board of Directors, but not less than its book value 


<PAGE>



on the such date. This Warrant is one of what is expected to be three identical
Warrants issuable pursuant to a loan transaction entered into on this date
between PICKNET, INC., a wholly-owned subsidiary of the Company, and the Holder.
A second Warrant shall be issued to the Holder at the Second Advance, as defined
hereafter, to purchase an additional 200,000 shares of Common Stock at any time
or from time to time during the one-year period from the day Holder makes the
second advance of $1,000,000 to PICKNET under its loan to PICKNET (the "Second
Advance"), at the price of the Company's stock at the close of business on the
day of the Second Advance. A third warrant shall be issued to the Holder at the
Third Advance, as defined hereafter, to purchase an additional 100,000 shares of
Common Stock at any time or from time to time during the one-year period from
the day Holder makes the third advance of $500,000 to PICKNET under its loan to
PICKNET (the "Third Advance") at the price of the Company's stock at the close
of business on the day of the Third Advance.

     The number of shares of Common Stock to be received upon the exercise of
this Warrant and the price to be paid for each share of Common Stock may be
adjusted from time to time as hereinafter set forth. The shares of Common Stock
deliverable upon such exercise, and as adjusted from time to time, are

                                       -2-

<PAGE>

hereinafter sometimes referred to as "Warrant Shares" and the exercise price of
a share of Common Stock in effect at any time and as adjusted from time to time
is hereinafter sometimes referred to as the "Exercise Price".

         (a) EXERCISE OF WARRANT. This Warrant may be exercised by presentation
and surrender hereof to the Company at its principal office or to the Company's
warrant agent, if any has been so appointed, with the Purchase Form annexed
hereto duly executed and accompanied by payment of the Exercise Price, in cash
or by certified or bank cashier's check, for the number of Warrant Shares
specified in such form. As soon as practicable after each such exercise of the
Warrants, the Company shall issue or cause to be issued and delivered to the
Holder a certificate or certificates for the Warrant Shares issuable upon such
exercise, registered in the name of the Holder. The Warrant shall be deemed to
have been exercised immediately prior to the close of business on the date of
any such exercise, provided such exercise is in accordance with the provisions
set forth herein. If this Warrant should be exercised in part only, the Company
shall, upon surrender of this Warrant for cancellation, execute and deliver a
new Warrant evidencing the rights of the Holder thereof to purchase the balance

                                       -3-

<PAGE>

of the Warrant Shares purchasable thereunder. Upon receipt by the Company of
this Warrant at its office in proper form for exercise, 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. Holder shall be
entitled to a cashless exercise of the warrant, in whole or in part.

         (b) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants.

         (c) FRACTIONAL SHARES. No fractional shares or script representing
fractional shares shall be issued upon the exercise of this Warrant. If more
than one Warrant shall be exercised at one time by the Holder, the number of
full shares which shall be issuable upon exercise thereof shall be computed on
the basis of the aggregate number of full shares issuable upon such exercise.


                                       -4-

<PAGE>

No adjustment shall be made in respect of cash dividends on Warrant Shares
delivered upon exercise of any Warrant. With respect to any fraction of a share
called for upon exercise hereof, the Company shall pay to the Holder an amount
in cash equal to such fraction multiplied by the average closing bid and asked
prices of the Common Stock on the last available date for which quotations are
available immediately preceding the date of exercise of this Warrant, or if the
bid and asked prices are not so reported, then the current market value shall be
an amount, not less than the book value thereof as at the end of the most recent
fiscal year of the Company ending prior to the date of the exercise of the
Warrant, determined in such reasonable manner as may be prescribed by the
Board of Directors of the Company.

         (d) EXCHANGE OR LOSS OF WARRANT. This Warrant is exchangeable, without
expense, at the option of the Holder, upon presentation and surrender hereof to
the Company for other Warrants of different denominations entitling the holder
thereof to purchase in the aggregate the same number of shares of Common Stock
purchasable hereunder. This Warrant may be divided or combined with other
Warrants which carry the same rights upon presentation hereof at the principal
office of the Company with a written notice specifying the denominations in

                                       -5-

<PAGE>

which new Warrants are to be issued and signed by the Holder hereof. The term
"Warrant" as used herein includes any Warrants into which this Warrant may be
divided or exchanged. Upon receipt by the Company or its warrant agent, if any,
of evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company will execute and deliver a new Warrant of
like tenor and date.

         (e) 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 the Warrant and
are not enforceable against the Company except to the extent set forth herein
and in any warrant agreement entered into by and between the Company and a
warrant agent with respect to the Warrants. In the event the Company enters into
a warrant agreement with a warrant agent, the terms of the Warrant shall be
embodied in the warrant agreement; and the acceptance of this Warrant by the
Holder shall be deemed consent by the Holder for the Company to enter into any
such warrant agreement, upon such terms and conditions mutually agreeable

                                      -6-
<PAGE>

between the Company and any such warrant agent, provided such warrant agreement
does not adversely affect any of the rights of the Holder, as set forth in this
Warrant.

         (f) ANTI-DILUTION PROVISIONS. After each adjustment of the Exercise
Price pursuant to this Section (f), the number of shares of Common Stock
purchasable upon the exercise of the Warrant shall be the number of Warrant
Shares receivable upon exercise thereof prior to such adjustment multiplied by a
fraction the numerator of which shall be the original Exercise Price as defined
above and the denominator of which shall be such adjusted Exercise Price. The
Exercise Price shall be subject to adjustment as set forth below:

                (i) In case the Company shall hereafter (A) pay a dividend or
make a distribution on its Common Stock in shares of its capital stock (whether
shares of Common Stock or of capital stock of any other class), (B) subdivide
its outstanding shares of Common Stock, or (C) combine its outstanding shares of
Common Stock into a smaller number of shares, the Exercise Price in effect
immediately prior to such action shall be adjusted so that the Holder of any
Warrant thereafter exercised shall be entitled to receive the number of shares

                                      -7-
<PAGE>

of capital stock of the Company which the Holder would have owned immediately
following such action had such Warrant been exercised immediately prior thereto.
An adjustment made pursuant to this subsection shall become effective
immediately after the record date in the case of a dividend and shall become
effective immediately after the effective date in the case of a subdivision.

               (ii) No adjustment in the Exercise Price shall be required to be
made unless such adjustment would require an increase or decrease of at least
$.10; provided, however, that any adjustments which by reason of this subsection
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section (f) shall be made
to the nearest cent or to the nearest one-one hundredth of a share, as the case
may be, but in no event shall the Company be obligated to issue fractional
shares upon the exercise of any Warrant.

              (iii) No adjustment of the Exercise Price shall be made except on
the conditions set forth in this Section (f). Without limitation to the
foregoing, there shall be no adjustment pursuant to this Section (f) should the


                                      -8-
<PAGE>

Company issue any capital stock for cash or other consideration on terms
approved by the Board of Directors.

               (iv) In case of any change of outstanding shares of Common Stock
issuable upon exercise of the Warrants (other than a change in par value or from
par value to no par value or from no par value to par value or as a result of a
subdivision or combination), or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with a Subsidiary
in which merger the Company is the continuing corporation and which does not
result in any reclassification or change of the then outstanding shares of
Common Stock or other capital stock issuable upon exercise of the Warrants other
than a change in par value or from par value to no par value or from no par
value to par value) or in the case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as an
entirety, then, as a condition of such change, consolidation, merger, sale or
conveyance, the Company, or such successor or purchasing corporation, as the
case may be, shall make lawful and adequate provision whereby the Holder of the
Warrant shall have the right thereafter to receive on exercise of such Warrant


                                      -9-
<PAGE>

the kind and amount of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock issuable upon
exercise of such Warrant immediately prior to such change, consolidation,
merger, sale or conveyance. Such provisions shall include provision for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided elsewhere in this Section (f). The above provisions of this
Section (f) shall similarly apply to successive consolidations, mergers, sales
or conveyances.

                (v) Before taking any action which would cause an adjustment
reducing the Exercise Price below the then par value of the shares of Common
Stock issuable upon exercise of the Warrants, the Company will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may validly and legally issue fully paid and non-assessable
shares of the Company at such adjusted Exercise Price.

         (g) PIGGYBACK REGISTRATION RIGHTS. If, at any time while any Warrant
Shares (as hereinafter defined) are outstanding, the Company shall file a
registration statement (other than on Form S-4, Form S-8, any other form that


                                      -10-
<PAGE>

does not permit secondary sales or any successor form) with the Securities and
Exchange Commission (the "Commission"), the Company shall give all the then
holders of any Warrant Shares (the "Eligible Holders") at least 30 days prior
written notice of the filing of such registration statement. If requested by any
Eligible Holder in writing within 30 days after receipt of any such notice and
if the Warrant Shares are eligible for registration under the registration
statement in question, the Company shall, at the Company's sole expense (other
than the fees and disbursements of counsel for the Eligible Holders and the
underwriting discounts, if any, payable in respect of the Warrant Shares sold by
any Eligible Holder), register or qualify all or, at each Eligible Holder's
option, any portion of the Warrant Shares of any Eligible Holder who shall have
made such request, concurrently with the registration of such other Warrant
Shares, all to the extent requisite to permit the public offering and sale of
the Warrant Shares through the facilities of all appropriate securities
exchanges and the over-the-counter market, and will use its best efforts through
its officers, directors, auditors and counsel to cause such registration
statement to become effective as promptly as practicable.

         Notwithstanding the foregoing, if the managing underwriter of any such
offering shall advise the Company in writing that, in its opinion, the


                                      -11-
<PAGE>

distribution of all or a portion of the Warrant Shares requested to be included
in the registration concurrently with the securities being registered by the
Company would materially adversely affect the distribution of such securities by
the Company for its own account, then any Eligible Holder who shall have
requested registration of his or its Warrant Shares shall delay the offering and
sale of such Warrant Shares (or the portions thereof so designated by such
managing underwriter) for such period, not to exceed 90 days (the "Delay
Period"), as the managing underwriter shall request. As used herein, "Warrant
Shares" shall mean the shares issued or issuable upon exercise or conversion of
a Warrant to Purchase Shares of Common Stock of the Company (including any
warrants issued upon the exercise or transfer of any such warrants in whole or
in part) issued to the Eligible Holders, which, in each case, have not been
previously sold pursuant to a registration statement or Rule 144 promulgated
under the Act. In addition to the foregoing, at such time that the Company
becomes eligible to register the Warrant Shares on Form S-3, the Company shall
do so and maintain the effectiveness of such Registration Statement until such
time as the Warrant Shares have been sold or can be sold pursuant to Rule
144(k). Any such registration shall be entirely at the Holder's expense.

                                      -12-
<PAGE>

         (h) INVESTMENT REPRESENTATION. By accepting this Warrant, the Holder
acknowledges that it is being taken for his own account as principal, for
investment purposes only, and not with a view to, or for, resale, distribution
or fractionalization thereof, in whole or in part, and no other person has a
direct or indirect beneficial interest in such Warrant and such Warrant may only
be transferred, subject to compliance with the legend set forth on the first
page. Unless the shares issuable upon the exercise of this Warrant are
registered under the Securities Act of 1933, as amended (the "Act"), the Holder,
upon exercise of this Warrant will be required to provide the Company with an
investment letter and the certificates representing such shares will contain a
legend to the effect that the Holder may not transfer, sell, pledge or
hypothecate such shares unless the registration provisions of the Act have been
complied with and unless the Company has received an opinion of counsel that
such registration is not required.

         (i) NOTICES. All notices and other communications which are required or
may be given under this Warrant shall be in writing and shall be deemed to have
been duly given when delivered in person or transmitted by telex or three (3)
days after being mailed, postage prepaid, in the case of the Company to Wayne



                                      -13-
<PAGE>

Interchange Plaza II, 155 Route 46 West, Wayne, NJ 07470, and in the case of the
Holder to the address set forth herein, or to such other address as such party
shall have specified by notice to the other party hereto. If notice is given by
registered or certified first class mail, postage prepaid, return receipt
requested, the return receipt shall be conclusive evidence of the notice having
been mailed on the date set forth.

         (j) MISCELLANEOUS. This Agreement contains the entire Agreement and
supersedes all prior agreements and understandings, oral or written, between the
parties hereto with respect to the subject matter hereof. This Warrant may not
be changed orally, but only by an agreement in writing signed by the party
against whom any waiver, change, amendment, modification or discharge is sought,
provided however, that this Warrant may be amended or modified without the
consent of the Holder if such amendment or modification does not adversely
affect the rights of the Holder hereunder. This Agreement will not be assigned
by either party hereto and shall be interpreted under the laws of the State of
New Jersey without application to the principles of conflicts of laws.
