               (b)  Counsel to Borrower shall have delivered an opinion to

               (c)  Borrower shall have paid all reasonable and ordinary fees of

defined below).

          5.   Limitations on Use of Loan Proceeds. Borrower shall not be

          6.   Representations and Warranties of Borrower and Wallner. Borrower,
and Wallner only as to 6.e., hereby makes the following representations and
warranties:

               a. Borrower is a Delaware corporation, duly organized, validly
existing and in good standing under the laws of the State of Delaware, and has
the requisite corporate power and authority to execute, deliver and perform its
obligations under this Loan Agreement.

               b. Borrower is duly qualified to conduct business as a foreign
corporation in good standing, and has obtained all necessary licenses and
approvals, in all jurisdictions in which the ownership or lease of property or
the conduct of its business shall require such qualification.

               c. The execution, delivery and performance by Borrower of this
Loan Agreement, the consummation of the transaction contemplated thereby, and
the fulfillment of the terms contained therein do not conflict with, result in
any breach of any of the terms and provisions of, nor constitute (with or
without notice or lapse of time) a default under, Borrower's articles of
incorporation or bylaws, or any indenture, agreement, mortgage, deed of trust or
other instrument to which Borrower is a party or by which it is bound or any of
its properties are subject; nor result in the creation or imposition of any lien
upon any of its properties pursuant to the terms of any such indenture,
agreement, mortgage, deed of trust, or other instrument; nor violate any law,
order, rule or regulation applicable to it or any of its properties, of any
court or
<PAGE>   3
of any federal or state regulatory body, administrative agency or other
governmental instrumentality having jurisdiction over Borrower or any of its
properties.

               d. The principal amount due and owing as of the date hereof under
the Initial Wallner Notes is $1,500,000.00 and $1,000,000.00, respectively, and
that the maturity dates have been extended to September 15, 2001. Borrower
hereby represents and warrants that it will not pay or otherwise satisfy its
obligations under the Initial Wallner Note or the June Wallner Note until the
Notes payable to the Lender has matured. Borrower shall not provide Wallner with
any collateral or otherwise secure any amounts due under the Initial Wallner
Note or the June Wallner Note without the written consent of the Lenders.

               e. Wallner will loan to Borrower, no later than June 5, 2001, the
sum of One Million Dollars ($1,000,000.00), such loan to be evidenced by a note
(the "June Wallner Note"), and the June Wallner Note shall be delivered to
Lender (care of Lenders counsel set forth in Section 11 hereof) and held as
collateral pursuant to the Security Agreement.

          7.   Representations and Warranties of Lenders. Each Lender, as to
itself only, hereby makes the following representations and warranties to the
Borrower, as to which Borrower relies in delivering the Note and the Warrant to
such Lender:

               a. Purchase for Own Account. The Note and any shares of common
stock received by Lender under the Warrant or by exercise of any conversion
rights under the Note (collectively, the "Stock") will be acquired for
investment for the Lender's own account, not as a nominee or agent, and not with
a view to the resale or distribution of any part thereof, and the Lender has no
present intention of selling, granting any participation in, or otherwise
distributing the Note or the Stock or any part thereof. The Lender does not have
any contract, undertaking, agreement or arrangement with any Person to sell,
transfer or grant participation to such Person with respect to the Note or the
Stock or any part thereof.

               b. Disclosure of Information. The Lender is aware of the
Company's business affairs and financial condition, has received and reviewed
all information (including reports filed by the Company with the Securities and
Exchange Commission up to the date hereof and including the Company's status
with its senior lenders) he considers necessary or appropriate for making an
informed and knowledgeable decision as to whether to acquire the Note and
further represents that he has had sufficient opportunity to ask questions and
receive answers from the Company regarding the nature and affairs of the
Company, including its business, properties, prospects and financial condition.

               c. Investment Experience. The Lender is an investor in securities
of companies and acknowledges that he is capable of bearing the economic risk of
its investment in the Note and the Stock, including the risk of total loss of
any or all of such investment, and has such knowledge and experience in
financial or business matters that he is capable of evaluating the merits and
risks of such investment.

               d. Accredited Investor. The Lender is an "accredited investor"
within the meaning of Commission Rule 501 of Regulation D, as presently in
effect.
<PAGE>   4
               e. Restricted Securities. The Lender understands and hereby
acknowledges that (i) the Note and the Stock it may receive upon conversion
pursuant to the provisions of the Note may not initially be registered under the
Securities Act of 1933 (the "Securities Act"), and in such event will be issued
in reliance upon a specific exemption from the registration requirements under
the Securities Act, which exemption depends upon, among other things, the bona
fide nature of the Lender's investment intent as expressed herein, and (ii) the
Note and Stock must be held indefinitely unless subsequently registered under
the Securities Act or unless an exemption from registration is available.

               f. Rule 144 Restrictions. The Lender is aware of the provisions
of Rule 144 promulgated under the Securities Act, which, in substance, permit
limited public resale of "restricted securities" acquired, directly or
indirectly, from the issuer thereof (or from an affiliate of such issuer), in a
non-public offering subject to the satisfaction of certain conditions, if
applicable, including, among other things: (i) the availability of certain
public information about the Company; (ii) the resale occurring not less than
one (1) year after the party has purchased and paid for the securities to be
sold; (iii) the sale being made through a broker in an unsolicited "broker's
transaction" or in transactions directly with a market maker (as said term is
defined under the Exchange Act) and the amount of securities being sold during
any three-month period not exceeding the specified limitations stated therein.

               g. Rule 144 Limitations. The Lender understands that Rule 144
does not apply to the Note. The Lender understands and acknowledges that at the
time it wishes to sell the some or all of the Stock there may be no public
market upon which to make such a sale, and that, even if such a public market
upon which to make such a sale then exists, the Company may not be satisfying
the current public information requirements of Rule 144, and that, in such
event, the Lender may be precluded from selling the Stock under Rule 144 even if
the one-year minimum holding period had been satisfied. The Lender further
understands that (i) if all of the requirements of Rule 144 are not satisfied,
registration under the Securities Act, compliance with Regulation A or
Regulation S under the Securities Act or some other registration exemption will
be required to permit the Lender to sale the Stock, and (ii) notwithstanding the
fact that Rule 144 is not exclusive, the staff of the Commission has expressed
its opinion that persons proposing to sell private placement securities other
than in a registered offering and other than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from registration
is available for such offers or sales, and that such persons and their
respective brokers who participate in such transactions do so at their own risk.

          8.   Debtor and Creditor. Lenders and Borrower intend that the
relationship between them be that of creditor and debtor only. Nothing herein
nor the acts of the parties hereto shall be construed to create a co-tenancy,
partnership, joint venture or similar relationship between Borrower and Lender.
Lender shall have no responsibility whatsoever for the debts, losses,
obligations or duties of Borrower. Borrower hereby indemnifies Lender and agrees
to defend and hold Lender harmless from and against any liability, claim,
demand, obligation, assessment, loss, cost, damage or expense of any nature
whatsoever (including, without limitation, any and all judgments, decrees,
settlements, awards and reasonable costs, expenses, attorneys' fees and court
costs), which are incurred, sustained, suffered, asserted or assessed against
Lender as a result of any claim, action suit or proceeding in which it is
alleged that Lender has liability to any person or entity because Lender and
Borrower have a relationship other than or in addition to
<PAGE>   5
that of creditor and debtor. The provisions of this Section 8 shall survive the
repayment of the Loan.

          9.   Assignment. This Loan Agreement may be endorsed, assigned and
transferred in whole or in part by Lender, and any such holder and assignee of
this Loan Agreement shall succeed to and be possessed of the rights of Lender
under this Loan Agreement to the extent transferred and assigned. This Loan
Agreement may not be endorsed, assigned or transferred by Borrower.

          10.  Entire Agreement. THIS AGREEMENT AND ALL OTHER INSTRUMENTS,
DOCUMENTS AND AGREEMENTS EXECUTED AND DELIVERED IN CONNECTION WITH THIS
AGREEMENT EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND
SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS AND
UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THIS AGREEMENT, AND MAY NOT
BE CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS OR DISCUSSIONS WITH THE PARTIES HERETO. THERE ARE NO ORAL
AGREEMENTS AMONG THE PARTIES HERETO. THIS AGREEMENT SHALL SUPERSEDE AND CONTROL
OVER THE SIMILAR PROVISIONS SET FORTH IN THE COMMITMENT.

          11.  Notices. All notices hereunder shall be deemed to have been duly
given and received (i) when personally delivered or transmitted by electronic

                               SECURITY AGREEMENT

          SECURITY AGREEMENT dated as of June 4, 2001, is made by George R.
Wallner ("Pledgor"), to individuals listed on Schedule A hereto ("Lenders")

          For valuable consideration and in order to induce Lenders to make the
loan represented by those Notes of even date herewith executed by Borrower in
favor of Lenders (the "Notes"), to Hypercom Corporation, a Delaware corporation
("Borrower"), including without limitation, Pledgor agrees as follows:

          SECTION 1. GRANT OF SECURITY. Pledgor hereby assigns, pledges, and
grants to the Lenders a security interest in all of the personal property
described in Schedule B hereto and all proceeds thereof (collectively the
"Collateral").

          SECTION 2. SECURITY FOR OBLIGATIONS. This Agreement secures the
payment and performance of the Notes (all such indebtedness and obligations of
Borrower being the "Obligations").

          SECTION 3. REPRESENTATIONS AND WARRANTIES. The Pledgor represents and
warrants as follows:

               (a)  Pledgor has full authority to enter into, deliver and
perform in accordance with the terms of this Agreement, and the granting of the
security interest to Lenders as provided herein does not contravene or violate
any agreement, law or document applicable to Borrower or Pledgor.

               (b)  The Collateral is owned by Pledgor and is and will be free
and clear of any lien, security interest, charge or encumbrance except for the
security interest created by this Agreement and such liens and encumbrances as
may be first approved in writing by Lenders. No financing statement covering the
Collateral or any proceeds thereof is on file in favor of anyone other than
Lenders.

          SECTION 4. FURTHER ASSURANCE. Pledgor agrees that from time to time,
at the expense of Pledgor, that he will promptly execute and deliver all further
instruments and documents, and take all further action that may be necessary or
desirable, or that Lenders may reasonably request, in order to perfect and
protect any security interest granted or purported to be granted hereby or to
enable Lenders to exercise and enforce its rights and remedies hereunder with
respect to any Collateral.

          SECTION 5. TRANSFERS AND OTHER LIENS. Pledgor shall not:

               (a)  Sell, assign (by operation of law or otherwise) or otherwise
dispose of any interest in the Collateral.

               (b)  Create or suffer to exist any lien, security interest or
other charge or encumbrance upon or with respect to any of the Collateral except
for the security interest created by this Agreement.
<PAGE>   2
          SECTION 6. LENDERS APPOINTED ATTORNEYS-IN-FACT. Pledgor hereby
irrevocably appoints Lenders the Pledgor's attorneys-in-fact, which such powers
of attorney are coupled with an interest, with full authority in the place and
stead of Pledgor and in the name of Pledgor, Lenders or otherwise, from time to
time in Lenders' discretion, to take any action and to execute any instrument
which Lenders may deem necessary or advisable to accomplish the purposes of this
Agreement, including, without limitation:

               (a)  to ask, demand, collect, sue for, recover, compound, receive
and give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral;

               (b)  to receive, endorse, and collect any drafts or other
instruments, documents or chattel paper in connection with the Collateral;

               (c)  to file any claims or take any action or institute any
proceedings which Lenders may deem necessary or desirable for the collection of
any of the Collateral or otherwise to enforce the rights of Lenders with respect
to any of the Collateral; and

               (d)  to sell, assign, transfer, pledge or otherwise enter into
agreements in connection with or otherwise deal with, any or all of the
Collateral as fully and completely as though Lenders were the absolute owner
thereof for all purposes. Upon the occurrence of an Event of Default and at any
time thereafter, Lenders shall have the right to take possession of all
Collateral.

          SECTION 7. LENDERS MAY PERFORM. If Pledgor fails to perform any
agreement contained herein, Lenders may themselves perform, or cause performance
of, such agreement, and the expenses of Lenders incurred in connection therewith
shall be payable by Pledgor.

          SECTION 8. LENDERS' DUTIES. The powers conferred on Lenders hereunder
are solely to protect their interest in the Collateral and shall not impose any
duty upon them to exercise any such powers. Except for the safe custody of any
Collateral in their possession and the accounting for moneys actually received
by them hereunder, Lenders shall have no duty as to any Collateral or as to the
taking of any necessary steps to preserve rights against prior parties or any
other rights pertaining to any Collateral.

               (a)  Borrower or Pledgor fails to pay, where due, all obligations
owing under the Notes;

               (b)  Pledgor breaches any representation, warranty, covenant or

          SECTION 10. REMEDIES. Upon the happening of any of the events
specified above:

               (a)  Lenders may exercise with respect to the Collateral any
remedy provided for herein, under any other agreement or otherwise available to
them, and all other rights and remedies of a secured party on default under the
Uniform Commercial Code (including the right to any deficiency remaining after
disposition of the Collateral for which Pledgor agrees to remain fully liable).

               (b)  Lenders may exercise any other rights or remedies they may
have either at law or in equity.

               (c)  All cash proceeds received by Lenders in respect of any

the discretion of Lenders, be applied in whole or in part by Lenders against all
or any part of the Obligations in such order and manner as Lenders shall elect.
Any surplus of such cash or cash proceeds held by Lenders and remaining after
payment in full of all the Obligations shall be paid over to Pledgor or to
whomsoever may be lawfully entitled to receive such surplus.

          SECTION 11. SECURITY INTEREST ABSOLUTE. All rights of Lenders and
security interest hereunder, shall be absolute and unconditional, irrespective
of:

               (a)  any lack of validity or enforceability of any note or other
loan document, agreement or instrument delivered to Lenders;

               (b)  any change in the time, manner, or place of payment of, or
in any other term of, all or any of the Obligations or any other amendment or
waiver of or any consent to any departure from any loan agreement, note, or
other loan document, agreement or instrument delivered to Lenders;

               (c)  any exchange, release or non-perfection of any other
collateral, or any release or amendment or waiver of or consent to departure
from any guaranty, for all or any of the Obligations; or

               (d)  any other circumstance which might otherwise constitute a
defense available to, or a discharge of, the Pledgor or a third party grantor of
a security interest.

          SECTION 12. GENERAL AGREEMENTS.

               (a)  Lenders shall not be deemed to have waived any of their
rights hereunder or under any other agreement, instrument or paper signed by
Pledgor unless such waiver is in writing and signed by Lenders. No delay or
omission on the part of Lenders in exercising any right shall operate as a
waiver thereof or of any other right. A waiver upon any one occasion shall not
be construed as a bar or waiver of any right or remedy on any future occasion.
All of the rights and remedies of Lenders, whether evidenced hereby or by any
other agreement, instrument or paper, shall be cumulative and may be exercised
consecutively or concurrently.

all Obligations and the termination of all agreements giving rise thereto in
accordance with their respective terms.

               (c)  Lenders and Pledgor are not and shall not be considered as
joint venturers, partners or agents of the other for purpose of fulfilling the
obligations of this Agreement and neither shall have the power to bind or
obligate the other. Neither Lenders nor Pledgor shall be liable for any of the
debts or other liabilities contracted by or due from the other and each will
hold the other free and harmless therefrom.

               (d)  If any provision of this Agreement or its application to any
person or circumstance is invalid or unenforceable, then the remainder of this
Agreement or the application of such provision to other persons or circumstances
shall not be affected thereby.

          SECTION 13. AMENDMENTS, ETC. No amendment or waiver of any provision
of this Agreement nor consent to any departure by Lenders herefrom shall in any
event be effective unless the same shall be in writing and signed by Lenders and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.
