                           PRINCIPAL AMOUNT: $400,000

The Parties to the  Extension  Agreement  are  OneSource  Technologies,  Inc., a
Delaware  corporation,  whose address is 2329 West Mescal,  Suite 304,  Phoenix,
Arizona 85029  (hereafter  the "Holder")  and Cossack  Financial,  LLC, a NV, AZ
corporation,  whose  address  is 7373 N  Scottsdale  PO  #16213  (hereafter  the
"Maker").

Recitals

Whereas,  Maker  has  made in favor  of  Holder  that  certain  Promissory  Note
(hereafter the "Note") a copy of which is attached  hereto as Exhibit "A" in the
principal  amount of Four Hundred  Thousand  ($400,000)  Dollars dated March 31,
1999 and payable  one  hundred  and eighty  days after date at six (6%)  percent
interest; and

Whereas,  the Note is currently due and payable at its original principal amount
plus accrued interest; and

Whereas,  the Parties  hereto  desire to extend the  maturity of the Note and to
provide for the additional  security of a joint brokerage account into which the
collateral  for the payment of the Note,  consisting  of 1,050,000 (MT initials)
shares of OneSource  Technologies,  Inc. common stock (hereafter the "Shares" or
the "Stock") shall be deposited by Maker; and

Whereas,  the  Parties  desire to provide  for the  orderly  liquidation  of the
Collateral so as to prevent  distortion in the market price of OneSource  common
stock which may occur upon a large lump sum sale;

Now Therefore For Good and Valuable Consideration The Receipt Of Which Is Hereby
Acknowledged, It Is Agreed As Follows:

Agreements

1.  Maker  hereby  acknowledges  and agrees  that the  amount of the Note,  plus
accrued  interest,  which  was due and  payable  as of  October  1, 1999 is Four
Hundred and Twelve Thousand  ($412,000.00) Dollars and No Cents. The term of the
Note,  which has  expired as of the date of the  Extension  Agreement,  shall be
extended  and the  maturity of the Note shall be upon  demand by Holders,  which
demand may be made at any time in the  Holder's  sole and  absolute  discretion,
with no conditions precedent to such demand, other than giving Notice and Demand
for Payment, and provided further that Maker shall make payments on account upon
the liquidation of the Collateral,  as required by Holder in accordance with the
provisions set forth below.

2. The Note is  secured  by the  security  interest  of Holder in the  Shares of
OneSource  Technologies,  Inc.  common  stock.  This Stock shall be deposited by
Maker and held in a joint signature brokerage account with Fidelity Investments,
Account Number  Y03155837,  listing both Maker and Holder as joint  signatories.
Both the Stock and any  proceeds  of the sale of the Stock  shall be held in the
account or in a money  market  account  with  Fidelity  which is  identified  as
Account  Number  291662471  and which shall be subject to the direction of Maker
and Holder as follows:

        a) Holder shall have the absolute discretion to pay or appoint to itself
        up to one hundred (100%) of any existing  balance of the proceeds of any
        Stock sale in the account either as such sales occur or later as

                                        1

<PAGE>

        Holder shall in its sole and absolute  discretion  deem  advisable.  Any
        amounts  disbursed  from proceeds held in the account to Holder shall be
        applied first to any costs associated with the collection of the Note or
        sale of any  security,  then to  accrued  interest,  and  finally to the
        principal  balance  due.  Holder  shall have no interest in any proceeds
        above the  amounts  due under the Note,  and upon  receiving  the entire
        proceeds as required  by the Note,  shall  consent to the removal of its
        name from the accounts.  Maker shall make no  disbursements  of proceeds
        either  to  itself  or to any third  party  without  the  prior  written
        approval of Holder.

        b) The  Shares of Stock held in the  account  may be sold in whole or in
        part  and  from   time  to  time  by  Maker,   for  good  and   valuable
        consideration,  which shall be deposited in the money market  account as
        proceeds.  Maker shall consult with, and obtain prior approval of Holder
        prior to any private placement of any Shares. Maker shall time all sales
        of Shares which it makes in such a way so as not to adversely impact the
        price of the Shares in the marketplace.

        c) In the event that insufficient Shares are sold so as to make periodic
        and satisfactory progress on the payment of the loan, which satisfactory
        progress  shall be  determined in the sole  discretion of Holder,  Maker
        agrees that, in addition to its other remedies at law,  Holder may, upon
        ten (10) days  notice to Maker,  assume  control of the  account and any
        remaining Stock or proceeds,  and sell such Stock for the benefit of the
        account of Maker.  Maker hereby waives, as to any proceedings under this
        provision by Holder to enforce its interest, any claim, cause of action,
        or damages or defense to  deficiency  in payment on the Note arising out
        of the sales or  failures  to sell Stock by Holder  during any period in
        which Holder is actively trading in the account.

        d) To  facilitate  Holder's  ability to manage the  account as  provided
        herein for the benefit of Maker, Maker hereby grants to Holder,  through
        its authorized representative, Donald Gause or such other representative
        as  OneSource  shall name from time to time,  a full power of  attorney,
        coupled  with an  interest,  to trade in the  account,  and buy and sell
        securities  therefrom in Holder's sole  discretion as to price,  amount,
        and timing, and to receive the proceeds therefrom, and to apply the same
        to  payments  due from Maker for the  benefit of the account of Maker at
        Holder's discretion.

3.  Notice,  in  writing,  shall be given by  Holder of its  election  to demand
repayment of the entire remaining balance of the Note. Notice shall be effective
when hand delivered to the noticed party or five (5) days after mailing, postage
prepaid in the U.S.  Mail to Maker's  last known  address,  or upon the next day
following  the date of deposit  of the  Notice  with an  overnight  carrier  for
overnight delivery.

4.  Maker  shall  have ten (10) days  grace  period  from the date of Notice and
Demand for  Payment in which to make  payment in full of the Note.  In the event
Maker does not pay, in full, all amounts due hereunder  prior to the termination
of the grace period, Maker shall be in default under its obligation.

5. From and after default,  and until the obligation of the Note,  together with
all accrued interest thereon and any expenses in connection therewith,  shall be
paid in full,  the Default  interest  rate of fourteen  (14%)  percent per annum
shall be applied to the outstanding balance due.

6. All of the terms and  conditions of the  Promissory  Note shall apply to this
Extension Agreement to the extent not in conflict herewith.

March 31, 1999

           One hundred and eighty days (180) after date, for value received, the
undersigned  promises  to  pay to  the  order  of  OneSource  Technologies  (the
"Company"),  at  2329 W. Mescal,  Suite 304, Phoenix,  Arizona, 85029, $400,000,
with  interest  from this  date,  at the rate of 6%  percent  per  year,  having
deposited with the Company the property described in the annexed schedule, which
the undersigned  warrants and represents is of a present market value of ______,
as  collateral  security  for the  payment  of this  note,  or any note or other
instrument  given in  extension  or  renewal  of this  note,  as well as for the
payment of all other present or future  liabilities  of the  undersigned  to the
Company,  including all costs and expenses which may be incurred by the Company,
or by the holder of this note,  in the  collection of this note or any extension
or  renewal  of it,  or in  the  collection  of  any  other  present  or  future
liabilities  of  the  undersigned  to  the  Company,  or in  sale,  delivery  or
protection of the deposited collateral,  or of any additions or substitutes,  or
of any other  property  in which a lien or security  interest  is given,  all of
which costs and expenses  (including  taxable  legal costs and charges for legal
services) the undersigned agrees to pay. The obligation  evidenced by this note,
and by any  extensions  or  renewals  in whole or in part,  and all of the other
obligations above specified,  are included in the expression "such  liabilities"
as used in this note.

           1.        Additional securities.

           The  undersigned   agrees  to  deliver  to  the  Company   additional
securities  to its  satisfaction,  on demand,  should  the  market  value of any
property  at any time held  hereunder  decline,  or should  any  change in their
marketability,  or should  any of such  securities  for other  reasons be deemed
unsatisfactory to the Company.

           2.        Transfer of collateral.

           The Company is authorized, in its discretion, whether or not any such
liabilities  are due, to transfer to its own name,  or to the name of a nominee,
any property  held as security;  and in its name, or in the name of any nominee,
or in the name of the  undersigned,  or  otherwise,  to sue for and  receive any
money or property at any time payable with respect to such property,  or to make
any compromise or settlement it deems desirable with respect thereto. Insofar as
any  collateral  shall consist of negotiable  instrument or chose in action,  in
whole or in part, as to other parties liable thereon,  without thereby incurring
responsibility to, or discharging,  or otherwise  affecting any liability of the
undersigned  and  the  undersigned  waives  presentation,   protest,  notice  of
nonacceptance,  and notice of nonpayment of all such  negotiable  instruments to
which the undersigned may be a party.

           3.        Default and acceleration.

           On the  nonperformance  of any of the promises continue in this note,
or upon the nonpayment of any such  liabilities  at maturity,  or in the case of
the  failure  of  the  undersigned  to  meet a  maturity  any  liability  of the
undersigned, either to the Company or to any other party, or upon the failure of
the undersigned  forthwith to furnish additional security to the satisfaction of
the insolvency or failure in business of, or appointment of a receiver,  trustee
or  custodian  for the  undersigned,  or the entry of any  judgment  against the
undersigned,  or the entry of any judgment  against the  undersigned,  or a levy
under a warrant of  attachment  upon the credit or property  of the  undersigned
with the  Company,  or in case any petition in  bankruptcy  shall be filed by or
against the  undersigned,  or any proceedings in bankruptcy or under any acts of
Congress  or other  governmental  authority  relating  to the  relief of debtors
should be commenced for the relief or  readjustments  of any indebtedness of the
undersigned,   either  through   reorganization,   composition,   extension,  or
otherwise,  all such liabilities of the undersigned  shall, at the option of the
Company, immediately mature and become forthwith due and payable, without demand
or notice.

<PAGE>

           4.        Sale of collateral.

           In the  event of  default,  full  power and  authority  are given the
Company to sell, assign, and deliver the whole or any part of such collateral at
public or private  sale,  or at any stock  exchange or brokers'  board,  at such
terms as it may deem best, without demand, advertisement, or notice of any kind,
all of which are  waived.  If any such  collateral  is  disposed of at a private
sale,  the Company shall be relieved from all liability or claim for  inadequacy
of price.  At any such sale,  the Company may itself  purchase  the whole or any
part of such  collateral,  free from any right of  redemption on the part of the
undersigned,  which is waived and  released.  If any such  collateral is sold on
credit or for future  delivery,  the  collateral  so sold may be retained by the
Company until the selling price is paid by the purchaser,  but the Company shall
incur no  liability  in case of failure of the  purchaser to take up and pay for
the collateral so sold. In case of any such failure, the collateral may be again
sold.

           5.        Application of sale proceeds.

           In case of sale for any  cause,  or of  receipt  of any  payments  of
principal or income on account of any such collateral, the Company may apply the
proceeds  of the sale or sales so made or the  payments  so  received to pay any
such of liabilities to the Company, as the Company or any one of the surplus, if
any, to the undersigned.

           6.        Continued liability.

           Notwithstanding the holding by the Company of such collateral for the
payment of such liabilities, or any sale, exchange, enforcement,  collection of,
realization  upon,  or  compromise  or  settlement,  actual or  attempted,  with
reference to any of such  collateral for the payment of such  liabilities or any
sale, exchange, enforcement,  collection of , realization upon, or compromise or
settlement,  actual or attempted, with reference to any of such collateral,  the
undersigned  shall be and  remain  liable  for the  payment  in full of all such
liabilities,  except  only to the  extent  that  such  liabilities,  or any part
thereof,  shall be reduced by payment,  or actual  application by the Company of
such collateral or the proceeds.

           7.        Waiver of inaction.

           The Company  shall not be liable for  failure to  collect,  or demand
payment of, or protest, or give notice of nonpayment of, such collateral, or any
part of it,  or for any  delay in so  doing,  nor  shall  the  Company  be under
obligation to take any action whatever in regard to such collateral or any part.

           8.        Substitutions, extensions.

           The collateral may from time to time, by mutual consent, be exchanged
for other property,  which shall be held by the Company subject to all the terms
of this note.  All the terms  hereof shall apply to all noted given in extension
or renewal of this note, and to all substituted and additional collateral.

           9.        Transfers.

           The Company may transfer this note,  and may deliver and transfer the
collateral or any part then held, to any transferee,  who shall thereupon become
vested with all the rights of the Company to the collateral so transferred,  and
the Company shall  thereafter be forever  relieved and fully discharged from all
liability or responsibility under this note as to such collateral or as indorser
or otherwise;  but as respects any  collateral  not so  transferred  the Company
shall retain all rights hereby given.

           10.       Waivers.

           No delay on the part of any  holder  of this note in  exercising  any
power or right  hereunder  shall operate as a waiver of any power or right;  nor
shall any single or partial  exercise  of any power or right  preclude  other or
further exercise,  or the exercise of any power or right, and no waiver whatever
shall be valid unless in writing, signed by the holder of this note, and only to

<PAGE>

the extent  therein  set forth.  Should the Company at any time make any call or
calls  for  collateral  or give any  notice  or  notices  of  intention  to sell
collateral,  or other  notices,  the  making of such calls or the giving of such
notices, no matter how many times repeated, shall not constitute a waiver of the
right of the Company to sell collateral, without demand or notice, in any of the
contingencies  in which the Company is  authorized  to sell  collateral  without
demand or notice.

           11.       Notice.

           Calls for collateral or any notices to the undersigned by the Company
shall be addressed to the undersigned at the address given below.

           12.       Miscellaneous.

           All  transactions  between the Company and the  undersigned are to be
construed according to the laws of the State of Colorado. Captions to paragraphs
are included for  convenience  only, and shall not apply to the  construction or
interpretation of this note.
