Dear Mark,

It is our pleasure to offer you the position of Senior Vice President and General Counsel with Marvell Semiconductor, Inc. ("the Company"), a subsidiary of Marvell Technology, Inc. (“Marvell”), at a salary of $430,000.00 USD per year.

Your supervisor will be Mitch Gaynor. Your work location will be Santa Clara, California.

You will be eligible to participate in the Company’s executive Annual Incentive Program (AIP) with a target bonus of 75% of your current base salary. The amount of your actual AIP bonus payment will be determined by the Company at its sole discretion based on a number of factors including but not limited to company and individual performance. Your bonus will be prorated for the fiscal year ending January 2022. You must be an active Company employee at the time of the bonus payout to be eligible for payment. It is clarified that the Company retains the right to modify, amend or terminate its plans and policies, including the AIP, from time to time, at its sole discretion. Any such modification or amendment will be communicated to you. It is also clarified that any payment of bonus or other compensation in one financial year, under any of the Company’s plans and/or policies does not create a right to claim such compensation or bonus from the Company in the future.

You will be recommended to the Executive Compensation Committee (“ECC”) for the following grants:

•Time Based Hire-On RSU Buy Award. A restricted stock unit award of common shares of Marvell equal to $2,900,000 (the “HORSU”) divided by the Share Price, subject to applicable securities law restrictions. The HORSU shall vest over a four (4) year period with 1/4th vesting on the first anniversary of the vesting start date and a further 1/16th vesting per quarter thereafter over the next succeeding three (3) years, provided that you continue to serve as an active employee through each applicable vesting date. The foregoing award is subject to applicable local laws and regulations and will be subject to your return to us of completed, signed award agreement (or acceptance of such award in accordance with the Company policies related to such awards).

•Buy-Out Transition Award. You will be recommended for a restricted stock unit award of common shares of Marvell equal to $400,000 (the “Buy-Out Award”) divided by the closing price of Marvell common stock on the effective date the grant is approved by Marvell’s executive compensation committee (or a subcommittee thereof), subject to applicable securities law restrictions. The Buy-Out Award shall vest over two years at the rate of 1/8th on the first quarterly anniversary of the vesting start date and 1/8th per quarter thereafter; provided that you continue to serve as an employee through each applicable vesting date.

•Refresh Equity Grant. The Company generally conducts its annual employee compensation review in Q1 of its fiscal year, including equity grants. With respect to the review scheduled to be conducted in March 2022, you will receive an additional equity award. It is expected that those awards will total approximately $1,600,000 and will be granted on and commence vesting on April 15, 2022 and it is also currently expected that such award will consist of a combination of (i) RSUs that will vest over a three (3) year period with 1/12th vesting per quarter over the succeeding three (3) years, provided that you continue to serve as an active employee through each applicable vesting date and (ii) performance based awards. The type and mix of awards will be identical to those awarded to other employees at the executive vice president level.

For the purposes of the HORSU and Buy-Out Award described above, “Share Price” shall mean the closing price of Marvell common stock on the effective date the grant is approved by Marvell’s ECC (or a subcommittee thereof), subject to applicable securities law restrictions.
