THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, AT THE END OF THE DAY ON AUGUST 27, 2018, UNLESS THE OFFER IS EXTENDED (SUCH DATE AND TIME, AS THEY MAY BE EXTENDED, THE "EXPIRATION DATE").

QUALCOMM Incorporated, a Delaware corporation ("Qualcomm"), has appointed us to act as Dealer Manager in connection with its offer to purchase for cash up to $10 billion in value of shares of its common stock, $0.0001 par value per share (the "Shares"), at a price not greater than $67.50 nor less than $60.00 per Share, to the seller in cash, less any applicable withholding taxes and without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase dated July 31, 2018 (the "Offer to Purchase"), and the related Letter of Transmittal (the "Letter of Transmittal," which together with the Offer to Purchase, as they may be amended or supplemented from time to time, constitute the "Offer"). Capitalized terms used herein and not defined herein shall have the meanings given to them in the Offer to Purchase. The description of the Offer in this letter is only a summary and is qualified by all of the terms and conditions of the Offer set forth in the Offer to Purchase and Letter of Transmittal.

Qualcomm will, upon the terms and subject to the conditions of the Offer, determine a single per Share price that it will pay for Shares properly tendered and not properly withdrawn from the Offer, taking into account the number of Shares so tendered and the prices specified, or deemed specified (as described in the Offer to Purchase), by tendering stockholders. Qualcomm will select the single lowest purchase price, not greater than $67.50 nor less than $60.00 per Share, that will allow it to purchase $10 billion in value of Shares, or a lower amount depending on the number of Shares properly tendered and not properly withdrawn. Upon the terms and subject to the conditions of the Offer, if, based on the Final Purchase Price (defined below), Shares having an aggregate value of less than or equal to $10 billion are properly tendered and not properly withdrawn, Qualcomm will buy all Shares properly tendered and not properly withdrawn. The price Qualcomm will select is sometimes referred to as the "Final Purchase Price." Only Shares properly tendered prior to the Expiration Date at prices at or below the Final Purchase Price and not properly withdrawn will be purchased in the Offer at the Final Purchase Price, upon the terms and subject to the conditions of the Offer, including the "odd lot" priority, proration and conditional tender provisions described in the Offer to Purchase. Under no circumstances will interest be paid on the purchase price for the Shares, regardless of any delay in making such payment. All Shares acquired in the Offer will be acquired at the Final Purchase Price. Qualcomm reserves the right, in its sole discretion, to change the per Share purchase price range and to increase or decrease the value of Shares sought in the Offer, subject to applicable law. In accordance with the rules of the Securities and Exchange Commission (the "SEC"), Qualcomm may increase the number of Shares accepted for payment in the Offer by no more than 2% of the outstanding Shares without extending the Offer.

Qualcomm reserves the right, in its sole discretion, to terminate the Offer upon the occurrence of certain conditions more specifically described in Section 7 of the Offer to Purchase, or to amend the Offer in any respect, subject to applicable law.

Upon the terms and subject to the conditions of the Offer, if, based on the Final Purchase Price, Shares having an aggregate value in excess of $10 billion, or such greater amount as Qualcomm may

elect to pay, subject to applicable law, have been validly tendered, and not properly withdrawn before the Expiration Date, at prices at or below the Final Purchase Price, Qualcomm will accept the Shares to be purchased in the following order of priority: (i) first, Qualcomm will purchase all Odd Lots of less than 100 Shares at the Final Purchase Price from shareholders who validly tender all of their Shares at or below the Final Purchase Price and who do not validly withdraw them before the Expiration Date (tenders of less than all of the Shares owned, beneficially or of record, by such Odd Lot Holder will not qualify for this preference); (ii) second, after purchasing all the Odd Lots that were validly tendered at or below the Final Purchase Price, from all stockholders who properly tender Shares at or below the Final Purchase Price, on a pro rata basis, subject to the conditional tender provisions described in the Offer to Purchase and with appropriate adjustment to avoid purchases of fractional Shares; and (iii) third, only if necessary to permit Qualcomm to purchase $10 billion in value of Shares (or such greater amount as Qualcomm may elect to pay, subject to applicable law), from holders who have tendered Shares at or below the Final Purchase Price subject to the condition that a specified minimum number of the holder's Shares be purchased if any Shares are purchased in the Offer as described in the Offer to Purchase (for which the condition was not initially satisfied) by random lot, to the extent feasible. To be eligible for purchase by random lot, stockholders whose Shares are conditionally tendered must have tendered all of their Shares. Therefore, it is possible that Qualcomm will not purchase all of the Shares tendered by a stockholder even if such stockholder tenders its Shares at or below the Final Purchase Price. Shares tendered at prices greater than the Final Purchase Price and Shares not purchased because of proration provisions will be returned to the tendering stockholders at Qualcomm's expense promptly after the Expiration Date. See Section 1, Section 3 and Section 5 of the Offer to Purchase.

The Offer is not conditioned on the receipt of financing or any minimum number of Shares being tendered. The Offer is, however, subject to certain other conditions. See Section 7 of the Offer to Purchase.
