          2.  Loans.
              -----

          (a)     So long as no Event of Default has occurred and is continuing,
Borrowers may at any time and from time to time prior to the Termination Date
request from Lender one or more Loans in an amount up to but not exceeding in
the aggregate at any one time outstanding the sum of $3,500,000 (including
amounts borrowed under the Old Note).

          (b)     Under the Old Note, loans in an aggregate amount of $400,000
have been made and such loans plus accrued and unpaid interest therein shall be
deemed to be outstanding Loans under this Note.  A Loan of $1,157,945.23 shall
be made when the Borrowers execute and deliver this Note, the Security Agreement
and the other collateral documents required to be delivered under the Security
Agreement and the Borrowers shall use the proceeds of such Loan to pay in full
the outstanding loans and other obligations under the Convertible Promissory
Note dated as of June 25, 2002 executed by Borrowers in favor of Hand Held
Products, Inc.  After the date hereof, Borrowers shall give Lender prior written
or oral notice of each subsequent Loan requested hereunder, specifying the
amount and date of each Loan.  Borrowers may not request more than one Loan in
any calendar week and each such request may not exceed $200,000 (or any higher
amount to the extent that Lender consents, in its sole discretion, to such
amount).  Each request for a Loan shall be accompanied by a written cash flow
projection setting forth the current cash position of Borrowers (which for these
purposes shall include the amount of any cash prepayment made by Federated
Department Stores less an amount needed by Borrowers to purchase parts inventory
specifically for the Federated contract) and the current cash needs of Borrowers
for the following week (showing the amount of anticipated expenditures by
general category) in order to allow Borrowers to operate in the ordinary course
of business.  If the weekly cash flow statement shows a projected cash flow
deficit, Lender will, prior to the Termination Date, make a Loan to Borrowers in
the amount of the deficit up to a maximum of $200,000 per week (or any higher
amount to the extent that Lender consents, in its sole discretion, to such
amount).  The proceeds of the Loan shall be made available to Borrowers to such
account or accounts as Borrowers may designate.


                                        2
<PAGE>
          (c)     Upon the making of Loans and the receipt of any payments on
Loans made hereunder, Lender is authorized to endorse the attached Schedule A
with an appropriate notation or to make appropriate notations on Lender's books
and records, provided that the failure to make any such notation (or any error
therein) shall not affect the obligations of the Borrowers to repay the Loans
made under this Note.  Such notations made by Lender shall be conclusive
evidence of all loans and payments made hereunder absent manifest error.

          3.  Interest.
              --------

          (a)     The outstanding principal balance of this Note shall bear
interest at a rate of 10% per annum.  In the event this Note is not paid on the
Maturity Date or following an Event of Default, the outstanding principal
balance of this Note shall bear interest at a rate of 15% per annum following
such date.

          (b)     Interest shall be calculated on the basis of a 365-day year
for the actual number of days elapsed.  Interest on the principal amount of all
outstanding Loans shall be payable in arrears on the first day of each month and
if not so paid shall be added to the principal balance monthly.

          4.  Principal.  The principal balance of this Note shall be paid on
              ---------
the Maturity Date.  Borrowers may prepay this Note in whole or in part at any
time without premium or penalty.  Borrowers shall make a mandatory prepayment of
the outstanding principal balance of this Note, and any accrued and unpaid
interest hereon, on the date on which either Borrower or POS's stockholders
enter into a transaction with a Person other than Lender which involves (i) a
merger or consolidation of either Borrower with another Person or the transfer
of any portion of the outstanding capital stock or assets to another Person or
(ii) a debt or equity financing by either Borrower; provided that, in the event
the financing does not raise proceeds (net of costs and expenses of the
financing transaction) equal to or in excess of $3,500,000, the mandatory
prepayment shall be limited in an amount to 50% of the net proceeds raised in
such financing transaction.

          5.  Adjustment of Principal Amount.
              ------------------------------

          (a)     The outstanding principal balance of this Note shall be
reduced by $350,000 in the event Lender becomes obligated to pay liquidated
damages to Borrowers under Section 10.3(c) of the Merger Agreement following a
termination of the Merger Agreement for one of the reasons specified in Section
10.3(c).  In such event, Borrowers shall be deemed to have offset the amount of
the liquidated damages owed by Lender against the outstanding balance hereof.

          (b)     The outstanding principal balance of this Note shall be
increased by $350,000 in the event Borrowers become obligated to pay liquidated
damages to Lender under Section 10.3(b) of the Merger Agreement following a
termination of the Merger Agreement for one of the reasons specified in Section
10.3(b).  In such event, Borrowers shall be deemed to have requested and
received an additional Loan in the amount of $350,000.


                                        3
<PAGE>
          6.  Payments.  All payments due under or pursuant to this Note shall
              --------
be made when due at such address as Lender may designate in writing from time to
time, in lawful money of the United States of America.

          7.  Collateral.  This Note is secured by a security interest in
              ----------
substantially all the assets of Borrowers granted pursuant to a Security
Agreement dated the date hereof (the "Security Agreement").  Upon the occurrence
                                      ------------------
of an Event of Default, Lender shall have all the rights and remedies set forth
in the Security Agreement.

          8.  Conversion.
              ----------

          (a)     Lender may at any time before or after the occurrence of an
Event of Default convert all or a portion of the unpaid principal balance of
this Note (including accrued and unpaid interest) into such number of shares of
Common Stock of POS as is equal to the product of (A) a fraction, the numerator
of which is the then-outstanding balance of this Note (including accrued and
unpaid interest) and the denominator of which is $5,000,000, and (B) the number
of shares of Common Stock outstanding on a fully diluted basis, including,
without limitation, shares of Common Stock issuable pursuant to (i) any
outstanding rights, options or warrant to subscribe for, purchase or otherwise
acquire shares of Common Stock or securities convertible into Common Stock and
(ii) outstanding indebtedness, shares or other securtities convertible into or
exchangeable for Common Stock.

          (b)     If Lender desires to convert this Note into shares of Common
Stock, Lender shall surrender this Note and shall give written notice to POS
that Lender elects to convert the same.  POS shall, as soon as practicable
thereafter, issue and deliver to Lender, a certificate or certificates for the
number of shares of Common Stock to which Lender shall be entitled.  Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of surrender of this Note, and Lender shall be treated for
all purposes as the record holder of such shares of Common Stock on such date.
If Lender elects to convert less than the entire outstanding balance of this
Note, Borrowers shall issue a replacement promissory note for the balance which
is not converted.

          (c)     POS will not, by amendment of its certificate of incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by POS, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 8 and in the taking of all
such action as may be necessary or appropriate in order to protect the
conversion rights of Lender against impairment.

          (d)     In the event of any taking by POS of a record of the holders
of any class of securities for the purpose of determining the holders thereof
who are entitled to (i) receive any dividend or other distribution, any security
or right convertible into or entitling the holder thereof to receive additional
shares of Common Stock, (ii) receive 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, or (iii) approve any transfer of
assets, consolidation, merger, dissolution


                                        4
<PAGE>
or other reorganization, Borrowers shall mail to Lender at least twenty (20)
days prior to the date specified therein, a notice specifying the date on which
any such record is to be taken for the purpose of such dividend, distribution,
security, or right, and the amount and character of such dividend, distribution,
security or right.

          (e)     POS shall pay any and all issue and other taxes (except taxes
measured by the net income of Lender) that may be payable in respect of any
issue or delivery of shares of Common Stock on conversion of this Note pursuant
hereto.

          (f)     POS shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the conversion of this Note, such number of its shares of Common Stock
as shall from time to time be sufficient to effect the conversion of this Note.
If at any time the number of authorized but unissued shares of Common Stock
shall not be sufficient to effect the conversion of this Note, POS will take
such corporate action as may be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purpose, including, without limitation, engaging in best efforts to
obtain the requisite stockholder approval of any necessary amendment to its
certificate of incorporation.

          (g)     In case of any reorganization or any reclassification of the
capital stock of POS, any consolidation or merger of POS with or into another
Person, or the conveyance of all or substantially all of the assets of POS to
another Person, this Note shall thereafter be convertible into the number of
shares of stock or other securities or property (including cash) which a holder
of the number of shares of Common Stock deliverable upon conversion of this Note
would have been entitled upon the record date of (or date of, if no record date
is fixed) such reorganization, reclassification, consolidation, merger or
conveyance; and, in any case, appropriate adjustment shall be made in the
application of the provisions herein set forth with respect to the rights and
interests thereafter of Lender, to the end that the provisions set forth herein
shall thereafter be applicable, as nearly as equivalent as is practicable, in
relation to any shares of stock or the securities or property (including cash)
thereafter deliverable upon the conversion of this Note.

          9.  Representations and Warranties.  The Borrowers jointly and
              ------------------------------
