NOTE 1: UNAUDITED INTERIM FINANCIAL STATEMENTS
 
    The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation S-X. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of only normal recurring accruals) considered necessary for a fair presentation
have been included. Operating results for the three and nine month periods ended
September 30, 1997 are not necessarily indicative of the results which may be
expected for the year ended December 31, 1997 or any other period. Reference is
made to the Consolidated Financial Statements and Notes thereto included in the
AX Acquisition Corporation's Schedule 14D-1 filing dated July 16, 1997, for
further information.
 
NOTE 2: BASIS OF PRESENTATION
 
    On August 21, 1997, pursuant to an Agreement and Plan of Merger dated as of
July 14, 1997 (the "Agreement of Merger"), AX Acquisition Corporation ("AX"), a
wholly-owned subsidiary of Axiohm S.A., acquired approximately 88%, or 7,000,000
shares, of the outstanding Common Stock of DH Technology, Inc. ("DH Technology")
through a public tender offer to the shareholders of DH Technology at a price of
$25 per share (the "Tender Offer").
 
    On October 2, 1997, pursuant to the Agreement of Merger, AX acquired 100% of
the outstanding Common Stock of Axiohm S.A. in exchange for 5,518,524 shares of
DH Technology Common Stock and $12.2 million in cash (the "Share Exchange
Offer"). Simultaneous with the Share Exchange Offer, DH Technology purchased all
of the outstanding shares of AX in exchange for the assumption of approximately
$190 million of debt (the "Acquisition Financing") incurred by AX to finance the
Tender Offer. Immediately after the Share Exchange Offer, AX was merged with and
into DH Technology (the "Merger"), the surviving legal entity, and the company
changed its name from "DH Technology, Inc." to "Axiohm Transaction Solutions,
Inc". Immediately after the Merger, approximately 85% of DH Technology's
outstanding Common Stock was held by the former shareholders of Axiohm S.A. and
15% was held by the former public shareholders of DH Technology, Inc. Axiohm
S.A. and its subsidiaries and DH Technology and its subsidiaries are hereinafter
referred to collectively as the "Company".
 
    The Tender Offer, the Share Exchange Offer and the Merger (collectively the
"Acquisition") have been accounted for as a reverse acquisition, in which Axiohm
S.A. was treated as the acquiror for accounting purposes. Accordingly, the
historical financial information for periods prior to August 31, 1997 are those
of Axiohm S.A. The effective date of the Acquisition and Merger of DH Technology
for accounting purposes was August 31, 1997, and, accordingly, the capital
structure of the Company has been retroactively restated to reflect the number
of shares outstanding as a result of the Acquisition. The results of operations
for the three and nine month periods ended September 30, 1997 include the
operations of DH Technology for the month of September 1997.

NOTE 3: ACQUISITION
 
    The Acquisition of DH Technology has been accounted for using the purchase
method of accounting. The aggregate purchase price of $208.6 million was
allocated based on the fair values of tangible and intangible assets acquired
and consisted of the following:

(1) Recorded as an increase to common stock on the accompanying condensed
    consolidated balance sheet.
 
    The Company expects that the final purchase price allocation will be known
by December 31, 1997 and could differ from the preliminary allocation. A summary
of the preliminary purchase price allocation is as follows:
 
<TABLE>

Total.........................................................  $208,629,000

                                                                -----------
</TABLE>
 
    The purchased in-process research and development had not reached
technological feasibility, had no future uses, and was charged to operations
upon acquisition. Goodwill and other intangibles are being amortized over three
years using the straight line method, which is the period estimated to be
benefited.
 
    Of the cash paid for the DH Technology stock options, $8.6 million was
funded to a Rabbi trust and is reflected on the balance sheet as restricted
cash.
 
    The Acquisition Financing consisted of $166.2 million of senior indebtedness
under a credit facility with an institutional lender and $24 million of interim
preferred stock financing. Both of these amounts were fully repaid on October 2,
1997 with the proceeds from a private placement of $120 million of 9 3/4% Senior
Subordinated Notes due 2007 and borrowings under an $85 million Credit
Agreement. See Note 5 of the Notes to Condensed Consolidated Financial
Statements.
 
    The following unaudited pro forma information has been prepared assuming
that the Acquisition and the Acquisition Financing had occurred at the beginning
of the periods presented. Pro forma adjustments included increased amortization
for the purchase price in excess of assets acquired; in-process research and
development expense; increased interest expense from the Acquisition Financing;
and related income tax

NOTE 5: SUBSEQUENT EVENTS
 
    SENIOR SUBORDINATED NOTES
 
    On October 2, 1997, the Company completed a private placement (the "Senior
Notes Offering") of $120 million of its 9 3/4% Senior Subordinated Notes due
2007 (the "Senior Notes"). The Senior Notes were placed with Lehman Brothers
Inc. as initial purchaser (the "Initial Purchaser") and were subsequently resold
by the Initial Purchaser in the United States to "qualified institutional
buyers" in reliance on Rule 144A under the Securities Act of 1933, as amended,
(the "Securities Act") and outside of the United States in offshore transactions
to foreign investors in reliance on Regulation S under the Securities Act. The
underwriting discount to the Initial Purchaser was 2.75% of the principal amount
of the Senior Notes purchased (or an aggregate of $3.3 million).
 
    Interest on the Senior Notes is payable semi-annually on April 1 and October
1, commencing on April 1, 1998, until maturity on October 1, 2007. The Senior
Notes are redeemable at the option of the Company, in whole or in part, at any
time on or after October 1, 2002 at various premiums to original face value. The
Company's payment obligation under the Senior Notes is jointly and severally
fully and unconditionally guaranteed on a senior subordinated basis by certain
of the Company's subsidiaries ("the Guarantors"), all of which are directly or
indirectly wholly-owned by the Company. The proceeds from the

sale of the Senior Notes, together with borrowings under the $85 million Credit
Agreement (see below) and existing cash were used to repay principal and accrued
interest under the Acquisition Financing.
 
    Pursuant to a Registration Rights Agreement dated October 2, 1997 (the
"Registration Rights Agreement") among the Company, certain of the Company's
U.S. subsidiaries, as Guarantors, and the Initial Purchaser, the Company and the
Guarantors have agreed to use their best efforts to file a registration
statement no later than 60 days after the closing of the Senior Notes Offering,
with respect to an offer to exchange the Senior Notes for new senior
subordinated notes of the Company (the "New Notes") registered under the
Securities Act, with terms identical to those of the Senior Notes, and to cause
such registration statement to become effective no later than 120 days after the
closing of the Senior Notes Offering. The Senior Notes and the New Notes are
hereinafter referred to collectively as the "Notes". The holders of the Notes
are entitled to certain penalty payments from the Company under certain
circumstances if the Company and the Guarantors are not in compliance with their
obligations under the Registration Rights Agreement.
 
    The following consolidating financial information is presented for purposes
of complying with the reporting requirements of the Guarantor Subsidiaries.

Guarantor Subsidiaries are not presented because the Company believes that such

    SENIOR BANK CREDIT AGREEMENT
 
    On October 2, 1997, the Company entered into a Credit Agreement (the "Credit
Agreement") with a syndicate of banks (the "Banks"), led by Union Bank and
Lehman Brothers which acted as agent. Pursuant to the Credit Agreement, the
Banks have extended the Company a two tranche amortizing term loan in the
original principal amount of $50 million (the "Term Loan") and established a $35
million revolving line of credit (the "Revolver") available through October 2,
2002. The Term Loan consists of a Tranche A term loan in an aggregate principal
amount of $35 million, which has a maturity of five years, and a Tranche B term
loan in an aggregate principal amount of $15 million, which has a maturity of
six years. The Term Loan and Revolver are secured by a lien on substantially all
of the real and personal property of the Company and certain of its subsidiaries
and a pledge of capital stock of certain of its subsidiaries (provided that no
lien was or will be granted on the assets of Foreign Subsidiaries (as defined)
and no capital stock of Foreign Subsidiaries will be pledged to the extent that
the granting of such lien or the making of such pledge would result in
materially adverse United States federal income tax consequences to the Company
or would violate applicable law). The proceeds of the Term Loan and the initial
advance under the Revolver were used by the Company to repay principal and
accrued interest under the Acquisition Financing. Both the Term Loan and the
Revolver have interest rate options including an interest rate based on the
Eurodollar Rate plus a margin of between 2.5% to 3%. Such margins will vary
depending upon the relationship between the Company's earnings before interest,
taxes, depreciation and amortization ("EBITDA") and the then aggregate total
debt outstanding. The Company is required to pay a fee of 0.375% per annum on
the unused portion of the Revolver. Under the Credit Agreement, the Company is
required to enter into arrangements to provide interest protection for $20
million of this floating rate debt for two years. The Credit Agreement contains
various restrictive covenants with which the Company must comply. The more
significant covenants relate to: limitations of capital expenditures,
established maximum debt to EBITDA ratios, minimum interest coverage ratios,
minimum fixed charge ratios, and limitations on indebtedness related to capital
leases and certain of the Company's subsidiaries. Required principal payments
under the New Credit Facility and Notes are as follows: $3.2 million in 1998;
$7.85 million in 1999; $7.85 million in 2001; $9.3 million in 2001; $9.3 million
in 2002; $12.5 million in 2003; and $120 million in 2007.
 
NOTE 6: SHAREHOLDERS EQUITY
 
    On June 24, 1996, Axiohm received net proceeds of $3.8 million from a
private placement of 421,200 shares of Common Stock to an employee of Axiohm and
two institutional investors.
 
    On June 24, 1996, Axiohm declared a cash dividend of $0.4 million on Common
Stock which was paid to shareholders of record on June 24, 1996.
 
    On May 14, 1997, Axiohm declared a cash dividend of $1.8 million on Common
Stock which was paid to shareholders of record on May 14, 1997.
 
    In September 1997, in connection with the Acquisition an officer of the
Company was granted options to purchase 231,118 shares of the Company's Common
Stock at an exercise price of $7.15 per share. The fair market value of the
Company's Common Stock was $17 per share on the date of grant, resulting in
compensation expense totalling $2,277,000. Included in the accompanying
condensed consolidated statement of operations for the nine months ended
September 30, 1997 is $455,000 of this total charge. The remaining $1,822,000 of
compensation expense will be recognized over a four year period coinciding with
with the option vesting schedule.
 
NOTE 7: COMMITMENTS AND CONTINGENCIES
 
    In connection with the August 1994 acquisition by DH Technology of all of
the outstanding stock of Cognitive Solutions, Inc. ("Cognitive"), a designer,
manufacturer and marketer of thermal bar code printers and complementary label
media for use in automatic data collection systems, the Company is
 
                                       13

NOTE 7: COMMITMENTS AND CONTINGENCIES (CONTINUED)
obligated to pay $0.5 million on August 15 in each of 1998 and 1999. The Company
also may be required to make additional payments, not to exceed $3.0 million, to
the former shareholder of Cognitive, based upon net sales of a specified
Cognitive product line.
 
    In connection with the December 1994 acquisition by Axiohm S.A. of the
transaction printer business of NCR Corporation ("NCR"), now known as Axiohm
IPB, for up to $30.6 million, of which $15.6 million was paid at closing, $0.5
million has been paid to date in earn-out payments and a final payment of up to
$5.0 million may be paid in additional earn-out payments based upon 1997 sales.
The Company estimates that the final payment will be less than approximately
$1.5 million and is anticipated to be paid in 1998. Axiohm S.A. recorded
approximately $3.0 million of goodwill in connection with this acquisition,
which was accounted for using the purchase method of accounting.
 
    In connection with the March 1997 acquisition by DH Technology of certain
assets and liabilities of American Magnetics Corporation ("AMC"), a designer,
manufacturer, and marketer of card reader modules and stand-alone card readers,
and a wholly-owned subsidiary of Group 4 Securitas Holdings, a Netherlands
company, for $5.7 million, of which $4.85 million was paid at closing, an
additional $0.8 million will become payable in the years of 2000 and 2001. Based
upon attainment of specified net sales, an additional $1.6 million may also
become payable.
 
    In connection with the purchase and improvement of manufacturing facilities
in France, Axiohm S.A. negotiated in 1994 a $1.6 million grant (the "Grant")
from various agencies of the French government. The Company is contingently
liable to those agencies for the repayment, in whole or in part, of the Grant in
the event that the Company does not meet the requirements of the Grant, which
include minimum employment levels through 1997, minimum capital expenditures and
continued use of the building throughout the lease term.
 
    In connection with the resignation of the Company's Chief Executive Officer,
the Company entered into a Resignation Agreement and a separate Noncompetition
Agreement dated January 10, 1998. The Resignation Agreement provides for
payments to the former President of approximately $1,525,000 pursuant to an
option cancellation agreement dated August 10, 1997. Additionally, the Company
will pay the former President $1,350,000 in consideration for his agreement not
to compete with the Company for a period of two years.
