                                  SCHEDULE 4(d)

In January, 2000, a claim was asserted against the Company by two shareholders
alleging fraud and material omission of fact as represented by a former Chief
Executive Officer of the Company. The claim alleges damages of $434,000.

On January 24, 2001, i-xposure, Inc. brought an action in the Superior Court for
Orange, California, against the company seeking to enforce certain guaranties
made by the company as a part of a bridge financing transaction for i-xposure.
The complaint seeks to recover approximately $351,000 pursuant to the
guaranties, costs and other relief deemed proper by the court. If the company is
unable to successfully defend this action, it might be forced to seek protection
under the bankruptcy laws.

                                 FORM OF WARRANT

THESE SECURITIES AND THE SECURITIES ISSUABLE UPON THEIR EXERCISE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED UNLESS
COVERED BY AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT, A "NO ACTION"
LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT TO SUCH
TRANSFER, A TRANSFER MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES AND
EXCHANGE COMMISSION, OR AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE
EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH REGISTRATION.

                                   ESAT, INC.

                          COMMON STOCK PURCHASE WARRANT

                1. Issuance; Certain Definitions. In consideration of good and
valuable consideration, the receipt of which is hereby acknowledged by ESAT,
INC., a Nevada corporation (the "Company"), WENTWORTH LLC, or registered assigns
(the "Holder") is hereby granted the right to purchase at any time until
____________________(the "Expiration Date"), _________________________ fully
paid and nonassessable shares of the Company's Common Stock, no par value per
share (the "Common Stock"), at an initial exercise price per share (the
"Exercise Price") of ________ subject to further adjustment as set forth herein.

                2. Exercise of Warrants.

                        2.1 General. This Warrant is exercisable in whole or in
part at any time and from time to time at the Exercise Price per share of Common
Stock payable hereunder, payable in cash or by certified or official bank check,
or by "cashless exercise," by means of tendering this Warrant Certificate to the
Company to receive a number of shares of Common Stock equal in Market Value to
the difference between the Market Value of the shares of Common Stock issuable
upon exercise of this Warrant and the cash exercise price thereof. Upon
surrender of this Warrant Certificate with the annexed Notice of Exercise Form
duly executed (which Notice of Exercise Form may be submitted either by delivery
to the Company or by facsimile transmission as provided in Section 8 hereof),
together with payment of the Exercise Price for the shares of Common Stock
purchased, if applicable, the Holder shall be entitled to receive a certificate
or certificates for the shares of Common Stock so purchased. For the purposes of
this Section 2, "Market Value" shall be an amount equal to the average closing
ask price of a share of Common Stock, as reported by Bloomberg, LP, for the five
(5) trading days preceding the Company's receipt of the Notice of Exercise Form
duly executed multiplied by the number of shares of Common Stock to be issued
upon surrender of this Warrant Certificate.

                        2.2 Limitation on Exercise. Notwithstanding the
provisions of this Warrant, the Securities Purchase Agreement (as defined below)
or of the other Transaction Agreements (as defined in the Securities Purchase
Agreement), in no event (except (i) with respect to an automatic conversion, if
any, of the Preferred Stock as provided in the Certificate of Designations or a
conversion pursuant to a Redemption Notice Conversion [as defined in the
Certificate of Designations], (ii) as specifically provided in the Certificate
of Designations as an exception to this provision, or (iii) if the Company is in
default hereunder or under any of the Transaction Agreements, and the Holder has
asserted such default in writing and the applicability of this provision to such
default) shall the Holder be entitled to exercise this Warrant or shall the
Company have the obligation, to issue shares upon such exercise of all or any
portion of this Warrant to the extent that, after such conversion, the sum of
(1) the number of shares of Common Stock beneficially owned by the Holder and
its affiliates (other than shares of Common Stock which may be deemed
beneficially owned through the ownership of the unconverted portion of the
Preferred Stock or unexercised portion of the Warrants), and (2) the number of
shares of Common Stock issuable upon the conversion of the Preferred Stock or
exercise of the Warrants with respect to which the determination of this proviso
is being made, would result in beneficial ownership by the Holder and its
affiliates of



<PAGE>   21

more than 9.99% of the outstanding shares of Common Stock (after taking into
account the shares to be issued to the Holder upon such conversion or exercise).
For purposes of the proviso to the immediately preceding sentence, beneficial
ownership shall be determined in accordance with Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "1934 Act"), except as otherwise provided
in clause (1) of such sentence. The Holder, by its acceptance of this Warrant,
further agrees that if the Holder transfers or assigns any of the Warrants to a
party who or which would not be considered such an affiliate, such assignment
shall be made subject to the transferee's or assignee's specific agreement to be
bound by the provisions of this Section 2.2 as if such transferee or assignee
were the original Holder hereof.

                3. Reservation of Shares. The Company hereby agrees that at all
times during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

                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.

                6. Protection Against Dilution.

                        6.1 Adjustment Mechanism. If an adjustment of the
Exercise Price is required pursuant to this Section 6, the Holder shall be
entitled to purchase such number of additional shares of Common Stock as will
cause (i) the total number of shares of Common Stock Holder is entitled to
purchase pursuant to this Warrant, multiplied by (ii) the adjusted purchase
price per share, to equal (iii) [the dollar amount of] the total number of
shares of Common Stock Holder is entitled to purchase before adjustment
multiplied by the total purchase price before adjustment.

                        6.2 Capital Adjustments. In case of any stock split or
reverse stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of this Section 6 shall be
applied as if such capital adjustment event had occurred immediately prior to
the date of this Warrant and the original purchase price had been fairly
allocated to the stock resulting from such capital adjustment; and in other
respects the provisions of this Section shall be applied in a fair, equitable
and reasonable manner so as to give effect, as nearly as may be, to the purposes
hereof. A rights offering to stockholders shall be deemed a stock dividend to
the extent of the bargain purchase element of the rights.

                        6.3 Adjustment for Spin Off. If, for any reason, prior
to the exercise of this Warrant in full, the Company spins off or otherwise
divests itself of a part of its business or operations or disposes all or of a
part of its assets in a transaction (the "Spin Off") in which the Company does
not receive compensation for such business, operations or assets, but causes
securities of another entity (the "Spin Off Securities") to be issued to
security holders of the Company, then

                (a) the Company shall cause (i) to be reserved Spin Off
        Securities equal to the number thereof which would have been issued to
        the Holder had all of the Holder's unexercised Warrants outstanding on
        the record date (the "Record Date") for determining the amount and
        number of Spin Off Securities to be issued to security holders of the
        Company (the "Outstanding Warrants") been exercised as of the close of
        business on the trading day immediately before the Record Date (the
        "Reserved Spin Off Shares"), and (ii) to be issued to the Holder on the
        exercise of all or any of the Outstanding Warrants, such amount of the
        Reserved Spin Off Shares equal to (x) the Reserved Spin Off Shares
        multiplied by (y) a fraction, of which (I) the numerator is the amount
        of the Outstanding Warrants then being exercised, and (II) the
        denominator is the amount of the Outstanding Warrants; and



                                       2
<PAGE>   22

                (b) the Exercise Price on the Outstanding Warrants shall be
        adjusted immediately after consummation of the Spin Off by multiplying
        the Exercise Price by a fraction (if, but only if, such fraction is less
        than 1.0), the numerator of which is the numerator of which is the
        Average Market Price of the Common Stock for the five (5) trading days
        immediately following the fifth trading day after the Record Date, and
        the denominator of which is the Average Market Price of the Common Stock
        on the five (5) trading days immediately following the fifth trading day
        after the Record Date, and the denominator of which is the Average
        Market Price of the Common Stock on the five (5) trading days
        immediately preceding the Record Date; and such adjusted Exercise Price
        shall be deemed to be the Exercise Price with respect to the Outstanding
        Warrants after the Record Date.

For the purposes of this Section 6.3, the "Average Market Price of the Common
Stock" shall mean, for the relevant period, (x) the average closing bid price of
a share of Common Stock, as reported by Bloomberg, LP or, if not so reported, as
reported on the over-the-counter market or (y) if the Common Stock is listed on
a stock exchange, the closing price on such exchange on the date indicated in
the relevant provision hereof, as reported in The Wall Street Journal.

                7. Transfer to Comply with the Securities Act; Registration
Rights.

                        (a) This Warrant has not been registered under the
Securities Act of 1933, as amended, (the "Act") and has been issued to the
Holder for investment and not with a view to the distribution of either the
Warrant or the Warrant Shares. Neither this Warrant nor any of the Warrant
Shares or any other security issued or issuable upon exercise of this Warrant
may be sold, transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel satisfactory to the Company that registration is not required under the
Act. Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.
