ALLAN QUATTRINPURCHASE AND SALE AGREEMENT

This agreement is made as of April 12, 2005, by and between InstaPay Systems,
Inc. ("IPYS"), a publicly traded corporation (OTCBB: IPYS) incorporated in Utah,
and Harry Hargens ("Hargens"), an individual residing in Georgia.

Whereas, in 2003 IPYS acquired Kryptosima LLC ("Krypto"), a Georgia Limited
Liability Company in a reverse-merger stock-swap with Krypto's then-owners
including Hargens; and,

Whereas, it was understood that IPYS would provide working capital to develop
the Krypto business; and,

Whereas, despite its best efforts, IPYS has often been unable to provide
sufficient working capital to meet these expectations; and,

Whereas, IPYS is currently unable to meet payments to maintain Krypto's
operational status, and wishes to divest itself of this monthly cash depletion;
and,

Whereas, this triggers a clause of Hargens' employment agreement requiring IPYS
to sell Krypto to him if it "abandons or discontinues" the Krypto business; and,

Whereas, IPYS and Hargens wish to resolve this matter amiably;

Therefore, the parties hereby agree as follows:

1)    Sale Of Krypto:

IPYS hereby agrees to sell Krypto to Hargens for $500,000, paid in the form of a
Promissory Note for $500,000 as set forth in Attachment A.

The transaction described by this agreement will be consummated by the delivery
to IPYS Chairman of an executed copy of said Promissory Note. Upon that
delivery, all ownership of Krypto shall move from IPYS to Hargens. Delivery may
be by courier delivery of a hardcopy, or email delivery of an electronic copy,
either method equally binding.

2)    Liabilities As Well As Assets:

IPYS will sell/Hargens will purchase the company (Kryptosima LLC) intact,
including all assets (including but not limited to computer equipment, patents,
contracts and inventory) and liabilities. This will eliminate over $500k of
liabilities from IPYS' consolidated financial statements. To avoid any confusion
regarding which liabilities Krypto holds versus which remain with IPYS, a list
of the liabilities that the parties agree are held by Krypto is given in
Attachment B.

<PAGE>

3)    Indemnification:

Deleted.

4)    Resignation:

Upon execution of this agreement by both parties, Hargens shall resign his
position as IPYS' CEO and as a Director of IPYS.

5)    Governing Law & Jurisdiction:

As set forth in Attachment A, the promissory note attached to this agreement.

Representations and Warranties:

6) Clear title; right to sell:

IPYS hereby represents and warrants that it has free and clear title to Krypto,
and the full and unencumbered right to sell it (except as encumbered by Hargen's
employment agreement). Should any 3rd party claim or threaten to make any claim
that it held any right to Krypto or any of its assets at the time of this
transaction, either directly or through a claim upon or security interest in
IPYS' assets, IPYS shall; Promptly notify Hargens in writing upon learning of
any such claim or threatened claim; Provide weekly updates until such claim is
resolved; At its own expense, vigorously defend against any such claim;
Cooperate with and take no action to hinder or interfere with any action Krypto
or Hargens may take to defend or resolve such claim. Any payments due to IPYS
under this agreement shall be suspended while any such claim is in question. The
amount due to IPYS shall be immediately reduced dollar-for-dollar by any defense
costs and any settlements that Krypto and/or Hargens pay, agree to pay, or are
ordered to pay to resolve any such claim. Since any such claim may disrupt
Krypto's business thereby impairing its ability to make the payments specified
herein, the due date any annual payment(s) due after learning of such a claim
will be moved to a later date, the move equaling the amount of time which such
claim remained unresolved.

7) No conflict with shareholder wishes:

As set forth in the preamble above, one purpose of this agreement is to amiably
resolve IPYS' obligations to Hargens under his employment agreement. Hargens'
employment agreement was described in IPYS SEC filings as early as the 10KSB
filed in April 2003, and a copy was attached as an exhibit to IPYS' SB2 filed in
June 2004. Therefore the employment agreement has been public knowledge for two
years. IPYS Chairman hereby warrants that to his knowledge IPYS' Board received
no negative shareholder comments regarding the terms of this agreement during
this period. Hargens has relied on this representation in assuming that this
transaction does not contravene shareholder wishes.

                                  Attachment A
                            $500,000 Promissory Note

Atlanta, Georgia                                                       $ 500,000

The undersigned, Kryptosima LLC., a Georgia Limited Liability Company (the
"Company"), promises to pay InstaPay Systems, Inc (the "Holder") at 419 main
Street, Suite 424, Huntington Beach, CA 92648 or such other address as the
Holder shall specify in writing from time to time, the principal sum of Five
Hundred Thousand (U.S.) Dollars and 00/100 ($500,000.00) payable pursuant to the
following terms:

1. Amount of Note. The face amount of this Promissory Note (this "Note") set
forth above, plus zero percent (0%) interest, shall be payable in annual
installments as set forth below, with the total to be paid within seven (7)
years from the date hereof.

2. Seven Annual Payments. The Company shall make annual payments to the Holder
on April 1st every year for seven (7) years, beginning April 1, 2006. Each
payment shall consist of 25% of The Company's net income (if any) for the
preceding calendar year; i.e. the April 1, 2006 payment shall be 25% of The
Company's net income for calendar year 2005. No minimum shall apply, i.e. the
annual payment will be zero if there was no net income in the preceding year.

Net income is defined as gross revenue (including, but not limited to,
transaction fees, and license fees received from any parties that Kryptosima
licenses its patents to), less all expenses (including but not limited to
operating expenses, cost of goods sold, and compensation for all staff including
management and owners working for the Company whether as employees and/or
consultants), taxes, interest expense, depreciation and amortization. Annual
financial statements provided by Krypto, which IPYS may have audited at its own
expense if it so chooses, will determine net income.

If April 1st falls on a weekend or business holiday, the payment will be due on
the first business day thereafter.

Any payment due but not made on time shall accrue interest at a rate of 1/2% per
month simple interest. Late payment shall not constitute a default.

3. Balance After 7th Annual Payments. Any remaining amount due after the 7th
annual payment (i.e. the April 1, 2012 payment) shall convert to equity (a %
ownership of the Company) as follows; 2.5% of ownership for each $50,000 or
fraction thereof still due.

0 ~ 50,000 = 2.5%;
50,001 ~ 100,000 = 5%
100,001 ~ 150,000 = 7.5%
:
:
500,000 = 25%

<PAGE>

If the amount still due after the 7th payment exceeds $250,000, then the Holder
shall also receive an unlimited license to two patents held by Kryptosima as of
the execution of this Note, and the right to issue sublicenses to these patents
and retain all fees it earns from issuing those sublicenses. This shall not
limit Kryptosima's right to continue to use or sublicense the patents, or affect
the fee arrangements or rights of any party associated with any previously
issued sublicenses.

(The patents referred to are US Patent # 6,834,271 and European Patent #
EP1218865).

4. Cancellation of Note. Upon repayment by the Company of its obligation
hereunder to the Holder, including, without limitation, the face amount of this
Note, plus accrued but unpaid interest, the indebtedness evidenced hereby shall
be deemed canceled and paid in full.

5. Severability. If any provision of this Note is, for any reason, invalid or
unenforceable, the remaining provisions of this Note will nevertheless be valid
and enforceable and will remain in full force and effect. Any provision of this
Note that is held invalid or unenforceable by a court of competent jurisdiction
will be deemed modified only to the extent necessary to make it valid and
enforceable and as so modified will remain in full force and effect.

6. Amendment and Waiver. This Note or any provision of this Note may be waived
or amended only if such amendment or waiver is set forth in a writing executed
by both parties hereto. The waiver by any such party hereto of a breach of any
provision of this Note shall not operate or be construed as a waiver of any
other breach.

7. Assignment. Neither party may directly or indirectly assign or delegate this
note.

8. No Strict Construction. The language used in this Note will be deemed to be
the language chosen by the parties hereto to express their mutual intent, and no
rule of strict construction will be applied against any party.

Court as set forth above, for the adjudication of any dispute hereunder or in
connection herewith or therewith, or with any transaction contemplated hereby or
discussed herein, and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is

consents to process being served in any such suit, action or proceeding by

shall constitute good and sufficient service of process and notice thereof.

any agreement, which is inconsistent with the rights granted to the parties in
this Note.

construed to confer upon or give to any person or entity, other than the parties

remedies under or by reason of this Note.

<PAGE>

13. Sale of Company. The Company currently has limited prospects. It is possible
that a time may come when the debt has not yet been fully paid, and the
Company's management determines that the best course of action is to sell
Krypto. This may be a distress sale in which no one gets their full value. The
holder will take no action to object to or block such a sale, and will accept
half of any net cash paid to purchase Krypto, up to the amount of debt still due
to IPYS, as payment in full of this note.

IN WITNESS WHEREOF, this Note is executed by the undersigned as of the date
hereof.
