Ladies and Gentlemen:
As legal counsel for QUALCOMM Incorporated, a Delaware corporation (the Company), we are
rendering this opinion in connection with the registration under the Securities Act of 1933, as
amended, of up to 116,049,451 shares of the Common Stock, $0.0001 par value (the Registration
Statement), of the Company which may be issued pursuant to the exercise of options and purchase
rights granted under the QUALCOMM Incorporated 2006 Long-Term Incentive Plan, as amended, and the
QUALCOMM Incorporated Amended and Restated 2001 Employee Stock Purchase Plan (the Plans).
We have examined all instruments, documents and records which we deemed relevant and necessary for
the basis of our opinion hereinafter expressed. In such examination, we have assumed the
genuineness of all signatures and the authenticity of all documents submitted to us as originals
and the conformity to the originals of all documents submitted to us as copies. We express no
opinion concerning any law other than the corporation laws of the State of Delaware and the federal
law of the United States. As to matters of Delaware corporation law, we have based our opinion
solely upon our examination of such laws and the rules and regulations of the authorities
administering such laws, all as reported in standard, unofficial compilations. We have not
obtained opinions of counsel licensed to practice in jurisdictions other than the State of
California.
Based on such examination, we are of the opinion that the 116,049,451 shares of Common Stock which
may be issued upon exercise of options and purchase rights granted under the Plans by QUALCOMM
Incorporated are duly authorized shares of the Companys Common Stock, and, when issued against
receipt of the consideration therefor in accordance with the provisions of the Plans, will be
validly issued, fully paid and nonassessable. We hereby consent to the filing of this opinion as
an exhibit to the Registration Statement referred to above and the use of our name wherever it
appears in said Registration Statement.
Respectfully submitted,
/s/ DLA Piper US LLP
