THIS IS A BALLOON NOTE AND THE FINAL PAYMENT OR THE BALANCE DUE IS UP TO

$480,000                                                Pittsburgh, Pennsylvania
                                                        February 17, 2006

       FOR VALUE RECEIVED, the undersigned XRG, INC., a Delaware ("Maker")
promise to pay to the order of BARRON PARTNERS, LP, or its assigns (hereinafter
sometimes referred to herein as "Lender" and together with any holder hereof
called "Holder") at such place or to such accounts as the Holder may from time
to time designate in writing, the principal sum of Four Hundred and Eighty
Thousand Dollars ($480,000), or such amount thereof as is advanced to Maker from
time-to-time, payable as set forth below.

       This Note shall bear PIK interest at a rate per annum of twelve percent
(12%). Interest shall be calculated on the basis of a 365 day year. Interest on
this Note shall begin to accrue from the date set forth above. All interest is
due and payable with the principal.

       All principal advanced under this Note, and accrued interest thereon, is
payable on or before December 31, 2006.

       All advances made under this Note shall be at the sole, absolute and
unfettered discretion of Holder. Holder is under no obligation to make advances
under this Note.

       "Event of Default", wherever used in this Note, means any one of the
following events:

            (1) failure to pay any installment of interest or the principal
balance due under this Note when such installment or principal amount becomes
due and payable;

            (2) the Maker shall commence (or take any action for the purpose
of commencing) any proceeding under any bankruptcy, reorganization, arrangement,
readjustment of debt, moratorium or similar law or statute;

            (3) a proceeding shall be commenced against Maker under any
bankruptcy, reorganization, arrangement, readjustment of debt, moratorium or
similar law or statute and relief is ordered against it, or the proceeding is
controverted but it is not dismissed within sixty (60) days after the
commencement thereof; or

            (4) Maker consents to or suffers the appointment of a receiver,
trustee or custodian for any substantial part of its assets that is not vacated
within thirty (30) days.

            (5) An event of default or an acceleration of indebtedness occurs
under any other obligation between Maker and Holder, including any other past or
future promissory notes and the Security Agreement (as defined below).

<PAGE>


       If an Event of Default occurs, then and in every such case, the Holders
may declare the entire unpaid principal balance of this Note, together with all
accrued interest, due and payable immediately by a notice in writing to the
Maker.

       If an Event of Default occurs, the Holder of this Note shall be entitled
to any and all of the remedies provided under New York Law. Upon declaration of
acceleration by the Holder hereof, the entire principal balance plus interest
accrued shall become immediately due and payable in full. The rights, powers,
privileges and remedies of the Holder of this Note are cumulative.

       This Note is secured by a Security Agreement (the "Security Agreement"),
encumbering all equipment, inventory, accounts receivable and general
intangibles and all other assts of Maker, all proceeds thereof, whether now
owned or hereafter acquired, including all additions and replacements thereof of
the Maker.

       The payment of principal and interest on this Note is subordinate to the
payment in full of all principal and interest on a $500,000 promissory note
payable to Kenneth A. Steel, Jr.

       If an Event of Default occurs, this Note shall bear PIK interest at
eighteen percent (18%) per annum until paid.

       In no event shall the amount of interest due or payments in the nature of
interest payable hereunder exceed the maximum contract rate of interest allowed
by applicable law, as amended from time to time. In the event any such payment
is paid by the Maker or received by the Holder, then, upon discovery of such
overcharge, the Holder shall immediately notify the Maker of such overcharge and
shall refund the amount thereof to the Maker; provided, however, the Maker has
the right to elect to have such overcharge applied to the reduction of principal
due hereunder.

       Time is of the essence of this contract and, if an Event of Default
occurs or if this Note is collected by law or through an attorney at law, or
under advice therefrom, the Maker agrees to pay all costs of collection,
including reasonable attorney's fees. Such attorney's fees and costs shall
include, but not be limited to, fees and costs incurred in all matters of
collection and enforcement, construction and interpretation, before, during and
after suit, trial, proceedings and appeals, including time spent and supervision
of paralegal work and paralegal time, as well as appearances in and connected
with any bankruptcy proceedings or creditor's reorganization or arrangement
proceedings.

       No act of omission or commission of the Holder, including specifically
any failure to exercise any right, remedy or recourse, shall be deemed to be a
waiver or release of the same, such waiver or release to be effected only
through a written document executed by the Holder and then only to the extent
specifically recited therein. A waiver or release with reference to any one
event shall not be construed as continuing, as a bar to, or as a waiver or
release of, any subsequent right, remedy or recourse as to a subsequent event.
