                      ------------
the "Shares") at an exercise price of $1.18 per Share (as adjusted pursuant to
     ------
Section 9 hereof, the "Exercise Price"). The "Termination Date" shall mean the

     1.   Title to Warrant. Prior to the expiration hereof, subject to
          ----------------
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company,
referred to in Section 2 hereof, by the Holder in person or by duly authorized
attorney, upon surrender of this Warrant together with the Assignment Form
annexed hereto properly endorsed, to any affiliate of such Holder.

     2.   Exercise of Warrant. The purchase rights represented by this Warrant
          -------------------
are exercisable by the Holder, in whole or in part, at any time following the
Closing (as defined in the Subscription Agreement) and before the close of
business on the Termination Date by the surrender of this Warrant and the Notice
of Exercise form annexed hereto duly executed at the office of the Company set
forth in Section 14.3 hereof (or such other office or agency of the Company as
it may designate by notice in writing to the Holder at the address set forth in
Section 14.3 hereof), and upon payment of the aggregate Exercise Price for the
Shares thereby purchased (by cashless exercise as set forth below, or by cash or
by check or bank draft payable to the order

                                        1
<PAGE>
of the Company or by cancellation of indebtedness of the Company to the Holder,
if any, at the time of exercise in an amount equal to the aggregate Exercise
Price of the Shares thereby purchased); whereupon the Holder shall be entitled
to receive a certificate for the applicable number of Shares.

     The Holder may provide notice of cashless election to the Company, in which
event the Company shall issue Holder a number of shares of Common Stock computed
using the following formula:

                                  X = Y(A-B)/A

     where:         X    = the number of shares of Common Stock to be issued to
                         Holder.

                    Y    = the number of shares of Common Stock for which this
                         Warrant is being exercised.

                    A    = the Market Price of one (1) share of Common Stock
                         (for purposes of this Section 3(ii), the "Market Price"
                         shall be defined as the average closing price of the
                         Common Stock for the five (5) trading days prior to the
                         Date of Exercise of this Warrant (the "Average Closing
                         Price")), as reported by the national securities
                         exchange or the automatic quotation system on which the
                         Common Stock is so traded and if not available, the
                         average of the high and low prices on the principal
                         national securities exchange or the automated quotation
                         system on which the Common Stock is so traded. If the
                         Common Stock is/was not traded during the five (5)
                         trading days prior to the Date of Exercise, then the
                         closing price for the last publicly traded day shall be
                         deemed to be the closing price for any and all (if
                         applicable) days during such five (5) trading day
                         period.

                    B    = Exercise Price.

     3.   Issuance of Stock and New Warrant; No Fractional Shares or Scrip.
          ----------------------------------------------------------------
Certificates for the Shares purchased hereunder or issuable upon exchange hereof
and, unless this Warrant has been fully exercised or exchanged, a new Warrant
representing the portion of the Shares with respect to which this Warrant shall
not then have been exercised or exchanged shall be delivered to the Holder
promptly after the date on which this Warrant shall have been exercised or
exchanged as aforesaid. The Company covenants that all Shares which may be
issued upon the exercise of rights represented by this Warrant will, upon
exercise of the rights represented by this Warrant, be fully paid and
nonassessable and free from all taxes, liens and charges in respect of the issue
thereof (other than taxes in respect of any transfer occurring contemporaneously
with such issue). The Company agrees that the Shares so issued shall be and be
deemed to be issued to the Holder as the record owner of such Shares as of the
close of business on the date on which this Warrant shall have been exercised or
exchanged as aforesaid. No fractional Shares or scrip representing fractional
Shares shall be issued upon the exercise or exchange of this Warrant. With
respect to any fraction of a Share called for upon the exercise or exchange of
this Warrant,

                                        2
<PAGE>
an amount equal to such fraction multiplied by the then current price at which
each Share may be purchased hereunder shall be paid in cash to the Holder.

     4.   Charges, Taxes and Expenses. Issuance of certificates for the Shares
          ---------------------------
upon the exercise or exchange of this Warrant shall be made without charge to
the Holder for any issue or transfer tax or other incidental expense in respect
of the issuance of such certificate, all of which taxes and expenses shall be
paid by the Company, and such certificates shall be issued in the name of the
Holder or in such name or names as may be directed by the Holder; provided,
however, that in the event certificates for Shares are to be issued in a name
other than the name of the Holder, this Warrant when surrendered for exercise or
exchange shall be accompanied by the Assignment Form attached hereto duly
executed by the Holder; and provided further, that upon any transfer involved in
the issuance or delivery of any certificates for the Shares, the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

     5.   No Rights as Stockholders. This Warrant does not entitle the Holder to
          -------------------------
any voting rights or other rights as a stockholder of the Company prior to the
exercise or exchange hereof.

     6.   Registry of Warrant. The Company shall maintain at the above-
          -------------------
mentioned office or agency a registry showing the name and address of the
Holder. This Warrant may be surrendered for exchange, transfer or exercise, in
accordance with its terms, at such office or agency of the Company, and the
Company shall be entitled to rely in all respects, prior to written notice to
the contrary, upon such registry.

     7.   Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the
          -------------------------------------------------
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it, and upon
surrender and cancellation of this Warrant, if mutilated, the Company will make
and deliver a new Warrant of like tenor and dated as of such cancellation, in
lieu of this Warrant.

     8.   Saturdays, Sundays, Holidays, etc. If the last or appointed day for
          ---------------------------------
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday or a Sunday or shall be a legal holiday, then such
action may be taken or such right may be exercised on the next succeeding day
not a Saturday, Sunday or legal holiday.

     9.   Adjustment of Exercise Price and Number of Shares. The number and kind
          -------------------------------------------------
of securities purchasable upon the exercise of this Warrant and the Exercise
Price shall be subject to adjustment from time to time upon the occurrence of
certain events, as follows.

     9.1  Reclassification or Merger. In case of any recapitalization,
          --------------------------
reclassification, reorganization or change of securities of the class issuable
upon exercise of this Warrant (other than a change in par value or as a result
of a subdivision or combination), the Company shall duly execute and deliver to
the Holder a new Warrant (in form and substance satisfactory to the Holder), or
in case of any merger of the Company with or into another corporation (other
than a merger with another corporation in which the Company is the acquiring and
the surviving corporation and which does not result in any reclassification or
change of outstanding securities

                                        3
<PAGE>
issuable upon exercise of this Warrant), or in case of any sale of all or
substantially all of the assets of the Company, the Company, or such successor
or purchasing entity, as the case may be, shall (i) duly execute and deliver to
the Holder a new Warrant as nearly equivalent as possible to this Warrant (in
form and substance satisfactory to the Holder) or (ii) make appropriate written
provisions without the issuance of a new Warrant, so that the Holder shall have
the right to receive upon exercise or exchange of this Warrant, at a total
exercise price not to exceed that payable upon the exercise of the unexercised
portion of this Warrant, and in lieu of the Shares theretofore issuable upon
exercise or exchange of this Warrant, the kind and amount of shares of stock,
other securities, money and property receivable upon such reclassification,
change, merger or sale by a holder of the number of Shares then purchasable
under this Warrant. Any new Warrant shall provide for adjustments that shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Section 9. The provisions of this subparagraph 9.1 shall similarly apply to
successive recapitalizations, reclassifications, reorganizations, changes,
mergers and transfers.

     9.2  Subdivision or Combination of Shares. If the Company at any time while
          ------------------------------------
this Warrant remains outstanding and unexpired shall subdivide or combine its
outstanding Shares, the Exercise Price shall be proportionately decreased in the
case of a subdivision and the number of Shares issuable hereunder shall be
proportionately increased in the case of a subdivision and the Exercise Price
shall be proportionately increased in the case of a combination and the number
of Shares issuable hereunder shall be proportionately decreased in the case of a
combination, effective at the close of business on the date the subdivision or
combination becomes effective.

     9.3  Stock Dividends and Other Distributions. If the Company at any time
          ---------------------------------------
while this Warrant is outstanding and unexpired shall pay a dividend with
respect to the Common Stock payable in additional shares of Common Stock, then
the Exercise Price shall be adjusted, from and after the date of determination
of stockholders entitled to receive such dividend or distribution, to that price
determined by multiplying the Exercise Price in effect immediately prior to such
date of determination by a fraction (A) the numerator of which shall be the
total number of shares of Common Stock outstanding immediately prior to such
dividend or  distribution and (B) the denominator of which shall be the total
number of shares of Common Stock outstanding immediately after such dividend or
distribution.

     9.4  Adjustment of Number of Shares. Upon each adjustment in the Exercise
          ------------------------------
Price, the number of Shares purchasable hereunder shall be adjusted, to the
nearest whole  share, to the product obtained by multiplying the number of
Shares purchasable immediately prior to such adjustment in the Exercise Price by
a fraction, the numerator of which shall be the Exercise Price immediately prior
to such adjustment and the denominator of which shall be the Exercise Price
immediately thereafter.

     9.5  Notice of Adjustments. Whenever the Exercise Price or the number
          ---------------------
and/or type of securities purchasable hereunder shall be adjusted pursuant to
this Section 9, at the written request of the Holder, the Company's President,
Chief Executive Officer or Chief Financial Officer shall sign a certificate
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated,
the Exercise Price, and the number and/or type of securities purchasable
hereunder after giving

                                        4
<PAGE>
effect to such adjustment, and shall cause a copy of such certificate to be
mailed by first class mail, postage prepaid to the Holder.

     10.  Restrictions on Transferability of Securities.
          ---------------------------------------------

     10.1 Restrictions on Transferability. This Warrant and the Shares issuable
          -------------------------------
upon exercise or exchange of this Warrant (collectively the "Securities") shall
                                                             ----------
not be sold, assigned, transferred or pledged except upon the conditions
specified in this Section 10, which conditions are intended to ensure compliance
with the provisions of the Securities Act of 1933, as amended (the "Securities
                                                                    ----------
Act"). Each holder of Restricted Securities (as defined below) will cause any
---
proposed purchaser, assignee, transferee, or pledgee of Restricted Securities
held by such holder to agree to take and hold such Restricted Securities subject
to the provisions and upon the conditions specified in this Section 10.

     10.2 Restrictive Legend. Each certificate representing the Securities and
          ------------------
any other securities issued in respect of the Securities upon any stock split,
stock dividend, recapitalization, merger, consolidation or similar event, shall
(unless otherwise permitted by the provisions of Section 10.4 below) be stamped
or otherwise imprinted with a legend in the following form (in addition to any
legend required under applicable state securities laws):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD, TRANSFERRED, OR
OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND IN COMPLIANCE
WITH APPLICABLE SECURITIES LAWS OF ANY STATE WITH RESPECT THERETO OR IN
ACCORDANCE WITH AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE
ISSUER THAT AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE AND ALSO MAY NOT BE
SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH ANY
APPLICABLE RULES OF THE SECURITIES AND EXCHANGE COMMISSION.

Each holder of Restricted Securities and each subsequent transferee (hereinafter
collectively referred to as a "Restricted Holder") consents to the Company
                               -----------------
making a notation on its records and giving instructions to any transfer agent
of the Securities in order to implement the restrictions on transfer established
in this Section 10. Securities represented by a certificate bearing the legend
set forth in this Section 10.2 are referred to herein as "Restricted
                                                          ----------
Securities."

     10.3 Restriction on Transfers. Each Restricted Holder of a certificate
          ------------------------
representing Restricted Securities, by acceptance thereof, agrees to comply in
all respects with the provisions of this Section 10.3. Restricted Holder agrees
that it will not sell or otherwise dispose of any of the Restricted Securities
unless such sale or other disposition has been registered under the Securities
Act or, in the opinion of counsel acceptable to the Company, is exempt from
registration under the Securities Act and has been registered or qualified or,
in the opinion of such counsel acceptable to the Company, is exempt from
registration or qualification under applicable state securities laws. Restricted
Holder understands that the offer and sale by the Company being acquired by
Restricted Holder hereunder has not been registered under the

                                        5
<PAGE>
Securities Act by reason of their contemplated issuance in transactions exempt
from the registration and prospectus delivery requirements of the Securities Act
pursuant to Section 4(2) thereof, and that the reliance of the Company on such
exemption from registration is predicated in part on these representations and
warranties of Restricted Holder. Each certificate evidencing the Securities
transferred as above provided shall bear the appropriate restrictive legend set
forth in Section 10.2 above, except that such certificate shall not bear such
restrictive legend if in the opinion of counsel for such Restricted Holder and
in the opinion of counsel for the Company such legend is not required in order
to establish compliance with any provision of the Securities Act.

     10.4 Removal of Restrictions on Transfer of Securities. Any legend referred
          -------------------------------------------------
to in Section 10.2 hereof stamped on a certificate evidencing the Securities and
the stock  transfer instructions and record notations with respect to the
Securities shall be removed, and the Company shall issue a certificate without
such legend to the Restricted Holder of the Securities if the Securities are
registered under the Securities Act, or if such Restricted Holder provides the
Company with an opinion of counsel (which may be counsel for the Company)
reasonably satisfactory to the Company to the effect that a public sale or
transfer of such security may be made without registration under the Securities
Act or such Restricted Holder provides the Company with reasonable assurances
that such security can be sold pursuant to paragraph (k) of Rule 144 (or any
successor provision) under the Securities Act.

     11.  Registration. The Company shall register the resale by Holder of all
          ------------
Shares issued or issuable hereunder under the Securities Act in the Shelf
Registration Statement (as defined in the Subscription Agreement).

     12.  Investment  Representations  of  the  Holder.  With  respect  to  the
          --------------------------------------------
acquisition of any of the Shares, the Holder hereby represents and warrants to
the Company as follows:

     12.1 Experience. The Holder has such knowledge and experience in financial,
          ----------
tax and business matters, including substantial experience in evaluating and
investing in  common stock and other securities (including the common stock and
other securities of speculative companies), so as to evaluate the merits and
risks of an investment in the Shares and to make an informed investment decision
with respect thereto. Investor is fully aware of: (i) the highly speculative
nature of the Shares; (ii) the financial hazards involved; (iii) the lack of
liquidity of the Shares and the restrictions on transferability of the Shares;
(iv) the qualifications and backgrounds of the management of the Company; (v)
the tax consequences of acquiring the Shares; and (vi) Investor understands that
the Shares are restricted and cannot be resold unless a registration statement
under the Securities Act (and current prospectus) is in effect as to the Shares,
the Shares are sold pursuant to Rule 144 of the Securities Act or pursuant to
another exemption from the registration requirements of the Securities Act or
applicable state securities laws. The Holder is an "accredited investor" as such
                                                    -------------------
term is defined in Rule 501(a) of Regulation D under the Securities Act (a copy
of which is attached as Exhibit D to the Subscription Agreement upon which the
Holder has indicated the specific definition with which the Holder complies),
and has such knowledge and experience in financial and business  matters that it
is capable of evaluating the merits and risks of the investment to be made by it
hereunder.

                                        6
<PAGE>
     12.2 Investment. The Holder is acquiring the Shares for investment for its
          ----------
own account and with no present intention of distributing or selling such Shares
and further agrees not to transfer such Shares in violation of the Securities
Act or any applicable state securities law, and no one other than the Holder has
any beneficial interest in the Shares. The Holder agrees that it will not sell
or otherwise dispose of any of the Shares unless such sale or other disposition
has been registered under the Securities Act or, in the opinion of counsel
acceptable to the Company, is exempt from registration under the Securities Act
and has been registered or qualified or, in the opinion of such counsel
acceptable to the Company, is exempt from registration or qualification under
applicable state securities laws. The Holder understands that the Shares have
not been, and except as otherwise provided in Section 11 will not be, registered
under the Securities Act by reason of their contemplated issuance in
transactions exempt from the registration and prospectus delivery requirements
of the Securities Act pursuant to Section 4(2) thereof, and that the reliance of
the Company on such exemption from registration is predicated in part on these
representations and warranties of the Holder.

     12.3 Rule 144. The Holder acknowledges that the Shares must be held
          --------
indefinitely unless subsequently registered under the Securities Act, or unless
an exemption from such registration is available. In addition, Holder has been
advised that Rule 144 promulgated under the Securities Act, which permits
certain limited sales of unregistered securities, may not be presently available
with respect to the Shares and, in any event, requires that the Shares be held
for a minimum of one (1) year, and in certain cases two (2) years, after they
have been purchased and paid for (within the meaning of Rule 144), before they
may be resold under Rule 144.

     12.4 Access to Data. The Investor has received from the Company, and has
          --------------
reviewed, such information which the Investor considers necessary or appropriate
to evaluate the risks and merits of an investment in the Shares, including
without limitation, the documents listed on Exhibit E to the Subscription
Agreement, which have been received by Investor as part of an informational
packet of materials from the Company. The Investor has had an opportunity to
discuss the Company's business, management and financial affairs and projections
with the Company's management and has also had an opportunity to ask questions
of the Company's officers, which questions were answered to its satisfaction,
and to verify information obtained in the Investor's examination of the Company.

     13.  Notices. If at any time prior to the exercise or exchange of this
          -------
Warrant in full the Company takes a record of the holders of the Company's
common stock for the purpose of determining the holders thereof who are entitled
to receive any dividend or other distribution, any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, the Company will give to
the Holder, at least thirty (30) days prior to the date specified therein,
written notice specifying the date on which any such record is to be taken for
the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right.

     14.  Miscellaneous.
          -------------

     14.1 Issue Date. The provisions of this Warrant shall be construed and
          ----------
shall be given effect in all respect as if it had been issued and delivered by

California without regard to choice of laws or conflict of laws provisions
thereof.

     14.2 Waivers and Amendments. With the written consent of the Company and
          ----------------------
the Holder, the obligations of the Company and the right of the Holder may be
waived (either generally or in a particular instance, either retroactively or
prospectively and either for a specified period of time or indefinitely), and
with the same consent the Company and the Holder may enter into a supplementary
agreement for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Warrant.

Francisco, California 94111; Fax: (415) 274-5669, or at such other address as
the Holder shall have furnished the Company in writing.

     14.4 Survival. The provisions of Section 10 hereof shall survive the
          --------
exercise or exchange of this Warrant and shall remain in effect until such time
as the Holder no longer holds Shares.

     14.5 Binding Effect on Successors. This Warrant shall be binding upon any
          ----------------------------
entity succeeding the Company by merger or consolidation. This Warrant shall not
be assignable by the Company without the prior written consent of the Holder.
All of the covenants and agreements of the Company shall inure to the benefit of
successors and assigns of the Holder.

<PAGE>PROMISSORY NOTE

$200,000                                                      September 11, 2002

FOR VALUE RECEIVED, the undersigned, Citadel Security Software Inc., a Delaware
corporation ("Citadel"), promises to pay to the order of Eagle Equity I, L.P.
("Payee"), at such place as Payee may designate in writing, in lawful money of
the United States of America, the principal sum of Two Hundred Thousand Dollars
($200,000) on the terms and conditions hereinafter set forth. This Note shall
bear interest at the rate of eight percent (8%) per year and shall mature on
January 11, 2003, at which time all outstanding principal shall be due and
payable.

Events of Default.  The entire unpaid principal balance of this Note shall
-----------------
immediately become due and payable, at the option of Payee, upon the failure by
Citadel to pay any installment of principal and interest hereof as and when the
same becomes due and payable in accordance with the terms hereof (the "Event of
Default").  In the event an Event of Default shall occur, the unpaid principal
shall accrue interest in the amount of 18% per annum and Payee may proceed to
protect and enforce its rights either by suit in equity and/or by action at law,
by other appropriate proceedings. No delay on the part of Payee in the exercise
of any power or right under this Note, or under any other instrument executed
pursuant thereto shall operate as a waiver thereof, nor shall a single or
partial exercise of any other power or right preclude further exercise thereof.

Conversion. Payee is entitled, at its option, at any time following a default
----------
under this Note and continuing until the indebtedness under this Note is repaid
in full, to convert all or a portion of the outstanding principal and accrued
interest under this Note into shares of common stock of Citadel (the "Shares").
No fractional Shares or scrip representing fractions of Shares will be issued on
conversion, but the number of Shares issuable shall be rounded to the nearest
whole Share.  Upon the surrender of this Note accompanied by a notice of
conversion, Citadel shall issue and deliver to Payee that number of Shares as
shall be determined in accordance herewith.  The number of Shares to be issued
upon conversion shall be determined by dividing the oustanding indebtedness
under this Note by the lesser of (a) $0.30 (the market price on the date of the
Note) and (b) the average of the closing bid and ask prices for Citadel shares
of common stock on the date immediately preceding the date of conversion.

Costs of Collection.  It is hereby specially agreed that if this Note is placed
-------------------
into the hands of an attorney for collection, or if proved, established, or
collected in any court, Citadel agrees to pay to Payee an amount equal to all
expenses incurred in enforcing or collecting this Note, including court costs
and reasonable attorneys' fees.

Waiver of Rights.  Except for the notice expressly provided herein, the
----------------
undersigned and all endorsers, sureties, and guarantors hereof hereby jointly
and severally waive presentment for payment, demand, notice of nonpayment,
protest, notice of protest, and without further notice hereby consent to
renewals, extensions, or partial payments either before or after maturity.

Adjustments for Stock Splits.  If Citadel at any time subdivides (by any stock
----------------------------
split, stock dividend, recapitalization or otherwise) its outstanding shares of
common stock into a greater number of shares, the number of Shares into which
this Note is convertible immediately prior to such subdivision will be
proportionately increased, and if Citadel at any time combines (by reverse stock
split or otherwise) its outstanding shares of common stock into a smaller number
of shares, the number of Shares into which this Note is convertible immediately
prior to such combination will be proportionately decreased.

Registration Rights.  If any Shares are outstanding and held by the Payee,
-------------------
Citadel shall use its best efforts to include the Shares and the additional
200,000 shares issued to Payee on the date of this Note (the "Payee Shares") in
any registration statement filed by Citadel with the Securities and Exchange
Commission (other than a registration statement on Form S-8 or Form S-4) to the
extent requisite to permit the public offering and sale of the Payee Shares and
will use their respective best efforts to cause such registration statement to
become effective as promptly as practicable. Notwithstanding the foregoing,
Citadel or the managing underwriter, if any,

                                      -1-
<PAGE>
of such offering may elect to exclude all or a portion of the Payee Shares if
the offering of such Payee Shares would adversely affect the market for
Citadel's securities or Citadel's business plans. As used herein, the "Payee
Shares" shall mean the Payee Shares that have not been previously sold or that
may not be resold pursuant to Rule 144 promulgated under the Act or other
available exemption. Notwithstanding the foregoing, Citadel shall not in any
event be required to keep any such registration or qualification in effect for a
period in excess of two years from the date on which the Payee is first free to
sell such Payee Shares.

In connection with registration of securities pursuant to this Note, Citadel
shall bear all expenses incurred in connection with such registration statement,
except that the Holder shall pay all fees and expenses with respect to its
shares, including broker/dealer commissions, underwriting discounts, the
expenses of such underwriter, fees and disbursements of counsel of Holder and
any stock transfer taxes incurred with respect of the Payee Shares of Holder.

Usury Limitation.  All agreements between Citadel and Payee, whether now
----------------
existing or hereafter arising and whether written or oral, are expressly limited
so that in no contingency or event whatsoever shall the amount paid, or agreed
to be paid, to Payee hereof for the use, forbearance, or detention of the money
advanced to Citadel, or for the performance or payment of any covenant or
obligation contained herein, exceed the maximum amount permissible under
applicable federal or state law.  If, from any circumstance whatsoever,
fulfillment of any provision hereof at the time performance of such provision
shall be due shall involve transcending the limit of validity prescribed by law,
then the obligation to be fulfilled shall be reduced to the limit of such
validity, and if from any such circumstance Payee shall ever receive as interest
under this Note or otherwise an amount that would exceed the highest lawful
rate, such amount that would be excessive interest shall be applied to the
reduction of the principal amount owing under this Note and not to the payment
of interest or, if such excessive interest exceeds the unpaid principal balance
of this Note, such excess shall be refunded to Citadel.  All sums paid or agreed
to be paid to Payee for the use, forbearance, or detention of the indebtedness
evidenced hereby shall, to the extent permitted by applicable law, be amortized,
prorated, allocated, and spread throughout the full term of such indebtedness
until payment in full so that the actual rate of interest on account of such
indebtedness is uniform throughout the term thereof.  The terms and provisions
of this paragraph shall control every other provision of all agreements between
Citadel and Payee.

Governing Law.  This Note shall be governed by and construed in accordance with
-------------
the laws of the State of Texas and the laws of the United States applicable to
transactions in Texas.
