Exhibit 10.9

20 August 2013

David Greene

Dear David:

We believe that you will make an important contribution to the success and growth of Aerohive Networks, Inc. (“Aerohive Networks,” or the “Company”). With this in mind, I am pleased to offer you the position of Chief Marketing Officer, reporting directly to me. This letter of agreement is intended to confirm the terms of your employment with Aerohive Networks.

Consistent with this position, you will be expected to perform job-related duties as I may assign to you from time-to-time. Your primary job location will be at Aerohive Networks’ office located in Sunnyvale, California, and at such other places as Aerohive Networks may direct over time. Your expected date of hire and commencement of employment with Aerohive Networks is identified below.

Cash Compensation. This is an exempt position and your initial base salary will be $250,000 on an annualized basis (before withholdings for applicable taxes, benefits, and other deductions). You will also be eligible to participate in our performance-based compensation program, which is based on quarterly pay-outs dependent upon achievement of MBOs defined and confirmed in writing by the Company. Your performance-based target is 25% of your base salary, 60% of which is based on Company performance and 40% of which is based on your individual performance, with potential payments pro-rated for each quarterly performance period.

All employment-related payments (including salary and expense reimbursements) will be payable in accordance with Aerohive Networks’ standard payroll schedule and process, and subject to withholding and payroll taxes and other deductions required by law.

Stock Award. In conjunction with your commencement of employment, we will propose that our Board of Directors approve an option for you to purchase 817,801 shares of our Common Stock (which is calculated based on 0.75% of the Company’s fully diluted capital as of June 30, 2013). This option award is subject to such Board approval, and to all terms and conditions of the specific Aerohive Networks option plan from which the option award would issue. Once approved (and subject to your continuing employment in good standing), 25% of the shares subject to the option award would vest after 12 month and the remaining shares would vest in equal monthly installments over the next 36 months, in each case subject to your continuous service in good standing (as described in the applicable stock option agreement).

Notwithstanding the foregoing vesting schedule, and consistent with similar protections offered to our executives, if, within twelve (12) months after a Change in Control (as defined in the Plan), you are terminated by the Company other than for Cause (as defined below), death, or disability (as defined in the Plan) or you resign for Good Reason (as defined below), and in either case you sign and do not revoke a standard form of release then-offered to the Company’s employees, then 50% of the then-unvested shares subject to your then-outstanding options at the time of your termination or resignation will immediately vest and become exercisable.

For purposes of this letter agreement, “Cause” shall mean:

in each case with respect to the foregoing, as determined by a resolution of the Board of Directors.

For purposes of this letter agreement, “Good Reason” shall mean your resignation within thirty (30) days following the expiration of any Company cure period (discussed below) following the occurrence of one or more of the following, without your consent:

You will not resign for “Good Reason” without first providing the Company with written notice of the acts or omissions constituting the grounds for “Good Reason” within ninety (90) days of your initial discovery of the grounds for “Good Reason” and providing to the Company a reasonable cure period of not less than thirty (30) days following the date of such notice. Your continued employment during any such discovery and cure period shall not constitute a waiver of your rights to assert Good Reason hereunder.

The Company agrees to review the foregoing protections and benefits available to you in the context of a Change of Control in the event prior to the first anniversary of commencement of your employment the Company enters agreements with its other executives to provide materially greater protections upon such Change of Control.

The exercise price of the shares subject to the award will be set at the time it is approved by our Board of Directors.

Benefits. Aerohive Networks offers what we feel is a very competitive benefits package. A brief summary of those benefits is enclosed for your review. You will need to review carefully the specific benefit plans to determine your eligibility and the applicable terms and conditions. Your eligibility to receive employee benefits and participate in Company-sponsored programs will be subject in each case to the specific applicable terms and conditions for the benefits programs in question (including as they may change or be administered over time). Please note that Aerohive Networks may from time to time, in its discretion, adjust the benefits available to you and the Company’s other employees.

At Will Employment. During your employment with Aerohive Networks, you will be expected to establish and maintain a professional, cordial relationship with co-workers, management, suppliers and customers. You will be expected to learn the requirements of the position and satisfactorily meet performance objectives over time.
