RE: Counteroffer

Dear Joe,

Thank you for your counter offer. I have reviewed your terms with Keith and our Human Resources director and have come to a consensus on the following terms in response:

* Salary: Starting salary to be $90,000. We feel this is in-line with other comparable jobs in the tech industry give your education and experience. We agree to the bi-weekly pay interval. Agreed

* Signing Bonus: You will receive a signing bonus of $15,000 paid in two parts; $5,000 paid within 15 days of acceptance and the remaining $10,000 paid the pay cycle following 30 days of employment. Agreed

* Options: You will receive 1500 stock options at a strike price equal to the share price of RR on the date of employment. In addition you will receive an additional 500 incentive options after your first year of employment and each subsequent anniversary on the same conditions stated in the original offer letter dated August 25, 2009. Agreed

* Relocation: We agree that your position is well suited to working via telecommunication provided you are willing to travel to our headquarters monthly for a full business week. All travel expenses will be paid for you by RR, however as there is no relocation, RR will not agree to a reimbursement as a condition of your virtual position. Should you decide to relocate to Silicone Valley at any time during your tenure with Robust Routers a reimbursement will be paid at that time for an amount no less than the original amount of $5,000 and will include cost of living adjustments from the time of your acceptance. Agreed

As a reminder, this offer is only valid until March 1, 2010. We feel these terms are competitive and just the beginning of a long and fruitful relationship between yourself and RR. I sincerely look forward to speaking with you soon!
