using the purchase method of accounting and the assumptions and adjustments
described in the accompanying notes to the unaudited pro forma combined
condensed financial statements. The unaudited pro forma combined condensed
financial statements were prepared as if the Acquisition had been completed as
of January 1, 2004 with respect to the statement of operations, and as of June
30, 2005 with respect to the balance sheet.

The unaudited pro forma combined condensed financial statements are based
on the respective historical consolidated financial statements of PCTEL and
Sigma. These unaudited pro forma combined condensed financial statements should
be read in conjunction with: i) PCTEL's Quarterly Report on Form 10-Q for the
quarter ended June 30, 2005 filed on August 9, 2005; ii) PCTEL's Quarterly
Report on Form 10-Q for the quarter ended March 31, 2005 filed on May 10, 2005;
iii) PCTEL's Annual Report on Form 10-K for the year ended December 31, 2004
filed on March 31, 2005; iv) Sigma's audited financial statements for the year

accompanying notes to the unaudited pro forma combined condensed financial
statements. The non-statutory historical financial statements of Sigma included
as Exhibit 99.2 to this Form 8-K have been presented in Euros and prepared in
accordance with generally accepted accounting principles in Ireland, whereas all
amounts for Sigma included herein have been presented in U.S. dollars and
prepared in accordance with U.S. generally accepted accounting principles ("U.S.
GAAP").

The unaudited pro forma combined condensed financial statements include
adjustments, which are based on preliminary estimates, to reflect the allocation
of the purchase price to the acquired assets and assumed liabilities of Sigma.
The purchase price allocation presented herein is preliminary, and final
allocation of the purchase price will be based upon actual net tangible and
intangible assets acquired as well as liabilities assumed as of the date of
Acquisition. Accordingly, final purchase accounting adjustments may differ from
the pro forma adjustments presented herein.

The unaudited pro forma combined condensed financial statements are
intended for information purposes only and, in the opinion of management, are
not necessarily indicative of the financial position or results of operations of
Sigma had the Acquisition actually been effected as of the dates indicated, nor
are they indicative of PCTEL's future financial position or results of
operations.

include potential cost savings from operating efficiencies or synergies that may
result from the Acquisition.

NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

The unaudited pro forma combined condensed financial statements included herein
have been prepared in accordance with the rules and regulations of the United
States Securities and Exchange Commission. Certain information and certain
footnote disclosures normally included in the financial statements prepared in
accordance with the accounting principles generally accepted in the United
States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and
regulations; however, management believes that the disclosures are adequate to
make the information presented not misleading.

1. BASIS FOR PRO FORMA PRESENTATION

On July 4, 2005, PCTEL, Inc. ("PCTEL") acquired all of the outstanding share
capital of Sigma Wireless Technologies Limited, an Irish company ("Sigma"),
pursuant to a Share Acquisition Agreement dated as of July 4, 2005 among PCTEL,
Sigma, the holders of the outstanding share capital of Sigma, and other parties
(the "Acquisition Agreement"). Sigma is based in Dublin, Ireland and develops,
manufactures and distributes antenna products designed for wireless
communications. The selling shareholders of Sigma consist of three
manager/directors of Sigma and an Irish corporation owned by affiliates of
Sigma.

The total purchase price was 23.4. million Euro (approximately $28.3 million).
Of this amount, 19.3 million Euro (approximately $23.4 million) was paid in cash
at the close of the transaction. Approximately 5.1 million Euro of the closing
payment were immediately used to discharge outstanding Sigma indebtedness and
retire outstanding preferred shares and the remaining 14.4 million Euro was paid
to the selling shareholders of Sigma. In addition, PCTEL assumed approximately
2.5 million Euro (approximately $3.0 million) of Sigma obligations, consisting
principally of unfunded pension liability. Transactions costs were approximately
$1.6 million euro (approximately $2.0 million).

The Acquisition Agreement also provides for an "earn-out" provision in favor of
the selling shareholders of Sigma, pursuant to which such shareholders may
receive up to an additional 7.5 million Euro (approximately $9.1 million) in
cash based on the revenue performance of Sigma over the 18-month period ending
December 31, 2006. A cash payment of up to 5.75 million Euro (approximately $7.0
million) of the 7.5 million Euro total possible earn-out will be made to such
shareholders based on Sigma revenue performance during the period in excess of
26 million Euro up to 35 million Euro; an additional cash payment of up to 1.75
million Euro (approximately $2.1 million) of the 7.5 million Euro total possible
earn-out will be made to such shareholders based on Sigma revenue performance
during the period in excess of 35 million Euro. Revenue performance of Sigma is
measured quarterly, and earn-out payments, if any, are to be made within 45 days
of the end of the quarterly period

The acquisition establishes a European presence for PCTEL, whose antenna sales
to date have been principally in North and South America and China. In addition,
the acquisition positions PCTEL in the rapidly growing UMTS infrastructure
market with leading edge antenna technology and associated control systems. The
new generation of cellular technology requires frequent optimization and the
ability to manage clusters of antennas.

The unaudited pro forma combined condensed balance sheet as of June 30, 2005 was
prepared by combining the historical condensed balance sheet for PCTEL and Sigma
as if the Acquisition had been consummated on June 30, 2005. The unaudited pro
forma combined condensed statements of operations for the year ended December
31, 2004, and for the three months ended June 30, 2005 and for the three months
ended March 31, 2005 give effect to the Acquisition as if it occurred on January
1, 2004.

2. PURCHASE PRICE ALLOCATION

The following represents the preliminary allocation of the purchase price paid
for Sigma based on the estimated fair values of the acquired assets and assumed
liabilities of Sigma as of June 30, 2005. The preliminary allocation of the
purchase price may not be indicative of the final allocation of the purchase
price consideration. Actual fair values will be determined as more detailed
analysis is completed and additional information becomes available related to
the fair values of the assets acquired and liabilities assumed from Sigma on
July 4, 2005.

The unaudited pro forma combined condensed financial statements reflect the
total initial purchase price of $28.4 million, consisting of the following: i)
the payment of initial cash consideration of 19.3 million euros ($23.4 million),
ii) estimated transaction costs of $2.0 million, and assumption of unfunded
pension liability of 2.5 million euro ($3.0 million). Under the purchase method
of accounting, the initial purchase price is allocated to Sigma's net tangible
and intangible assets based on the estimated fair value as of the date of
Acquisition. The initial purchase price does not include any contingent earn out
amounts. The preliminary purchase price allocation as of June 30, 2005 is as
follows: (in thousands):

TANGIBLE ASSETS:
Accounts receivable................................................... $ 2,113
Inventory............................................................. 3,065
Property and equipment................................................ 1,331
Prepaids and other current assets..................................... 318
-------
TOTAL TANGIBLE ASSETS: 6,827
-------

INTANGIBLE ASSETS:
Acquired Technology................................................... $ 2,541
Customer Relationships................................................ 6,536
Backlog............................................................... 48
Goodwill.............................................................. 16,393
-------
TOTAL INTANGIBLE ASSETS: 25,518
-------

LIABILITIES ASSUMED:
Accounts payable...................................................... $ 2,518
Accrued liabilities (including deferred revenue)...................... 946
Income tax liability 392
Pension liability..................................................... 3,046
-------
TOTAL LIABILITIES ASSUMED: 6,902
-------
NET ASSETS ACQUIRED: $25,443

A third-party appraiser prepared the valuation of the intangible assets. A
preliminary estimate of $16.4 million has been allocated to goodwill. Goodwill
represents the excess of the purchase price over the fair value of the tangible
and intangible assets acquired. In accordance with SFAS No. 142, "Goodwill and
Other Intangible Assets," goodwill will not be amortized but will be tested for
impairment at least annually. The purchase price allocation presented above is
preliminary and final allocation of the purchase price will be based upon the
actual fair values of the net tangible and intangible assets acquired, as well
as liabilities assumed as of the date of Acquisition. Any change to the fair
value of the net assets of Sigma will change the purchase price allocable to
goodwill. The final purchase accounting adjustments may differ materially from
the pro forma adjustments presented herein.

There were no historical transactions between PCTEL and Sigma.
