ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

        On February 21, 2000 (the "Closing Date"), QUALCOMM Incorporated
("QUALCOMM") and QUALCOMM Personal Electronics sold certain assets related to
their terrestrial-based wireless CDMA consumer phone business (the "Assets") to
Kyocera Wireless Corp. ("KWC"), formerly known as KII Acquisition Company,
pursuant to that certain Asset Purchase Agreement dated December 22, 1999 among
QUALCOMM, KWC and Kyocera International, Inc., as amended by that certain First
Amendment to Asset Purchase Agreement, dated as of February 20, 2000 (as
amended, the "Asset Purchase Agreement"). QUALCOMM received $216,144,412 in cash
on February 22, 2000 and will receive an additional $19,363,176, plus interest
from February 22, 2000, in cash on consummation of that aspect of the sale
relating to certain foreign business operations and assets (the "Second Closing
Date"). The Second Closing Date is expected to occur in March 2000. Initial
consideration for the Assets will total $235,507,588, provided however, that the
total consideration to be paid for the Assets will be based on a final
determination made after the Closing Date of the value of the net assets
actually sold.

        A description of the transaction is set forth in the Press Release
issued by QUALCOMM dated February 22, 2000, a copy of which is attached hereto

    NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION



(a)      The unaudited pro forma condensed consolidated balance sheet give
         retroactive effect to the sale of certain assets related to QUALCOMM's
         terrestrial-based wireless CDMA consumer phone business to Kyocera
         Wireless Corp. ("KWC") as if the sale had occurred as of December 26,
         1999. The unaudited pro forma condensed consolidated statements of
         income give retroactive effect as if the sale had occurred as of the
         beginning of the periods represented. The Company estimates that
         additional charges in the second quarter of fiscal 2000 relating to the
         disposition of the terrestrial-based wireless CDMA phone business will
         total approximately $50 million. The additional charges will primarily
         relate to KWC's right under the agreement to exclude certain properties
         and equipment and employee termination charges. Such charges are not
         considered in these unaudited pro forma condensed consolidated
         financial statements.

(b)      Reflects the initial cash proceeds to be received by QUALCOMM. Total
         consideration will be based on a final determination of net assets as
         of the closing date.

(c)      Reflects inventories, net of reserves, to be sold to KWC.

(d)      Reflects property and equipment, net of accumulated depreciation, to be
         sold to KWC.

(e)      Reflects accrued liabilities to be assumed by KWC, primarily comprised
         of warranty reserves and accrued cooperative advertising.

(f)      Reflects revenues related to the terrestrial-based wireless CDMA
         consumer phone business to be assumed by KWC, including $19 million in
         sales by QUALCOMM Personal Electronics ("QPE") to Sony Electronics Inc.
         ("Sony Electronics"), offset by royalty revenue from third parties and
         billings to KWC for services provided by QUALCOMM employees as a result
         of the sale. QPE, a joint venture general partnership formed by
         QUALCOMM and Sony Electronics, manufactured the terrestrial-based
         wireless CDMA consumer phones sold by QUALCOMM. Sony Electronics' 49%
         interest in QPE is presented as a minority interest in these unaudited
         pro forma condensed consolidated financial statements.

(g)      Reflects cost of revenues related to the terrestrial-based wireless
         CDMA consumer phone business to be assumed by KWC, offset by the cost
         of revenues related to services provided by QUALCOMM employees as a
         result of the sale.

(h)      Reflects research and development expenses related to the
         terrestrial-based wireless CDMA consumer phone business to be assumed
         by KWC.

(i)      Reflects selling, general and administrative expenses related to the
         terrestrial-based wireless CDMA consumer phone business to be assumed
         by KWC.

(j)      Reflects nonrecurring charges primarily related to the estimated
         difference between the carrying value of property and equipment and the
         consideration to be received from KWC, less costs to sell.

(k)      Reflects interest expense incurred by QPE in connection with the
         terrestrial-based wireless CDMA consumer phone business to be assumed
         by KWC.




                                       7

(l)      Reflects Sony Electronics' minority interest in the earnings of QPE.

(m)      Pro forma adjustments have been tax effected at QUALCOMM's annual
         effective tax rate, expected to be 38% for fiscal 2000. QUALCOMM's
         annual effective tax rate was 35% for fiscal 1999.

(n)      QUALCOMM effected a four-for-one stock split in December 1999. Pro
         forma net earnings per common share for the year ended September 30,
         1999 are presented giving retroactive effect to the stock split.
