To whom it may concern, As the Chief of Engineering at SMARTECH, I supervised Guy for his first four years at SMARTECH. Guy's fast learning curve was unlike any I have seen before. Soon enough, Guy demonstrated the mastery of his core role and the ability to take on new projects and execute them in the best way. These projects were complex and critical to the company's growth. Guy was involved in several critical positions in the company and excelled in each: 1. He was the lead mechanical engineer in SMARTECH, having immense responsibility and impact on our products. 2. As a senior engineer, he demonstrated extraordinary leadership to the design teams and mentored many junior team members. 3. As a PDM administrator, he independently led the foundation and implementation of the PDM system. 4. As part of the project team, he successfully led international projects throughout the entire process, including designing, manufacturing, implantation at the customer site, and customer support troubleshooting. One of Guy's remarkable traits is his ability to think a few steps ahead and try to understand what the reason is, what the cause is, and what can be done to prevent the problem. For example, we faced some problems with the pumps in our systems (these parts are "the heart of the machine"). Guy investigated the failure cause, developed a new pump housing for these pumps, and upgraded the inner parts to prevent them from failing and extending their "life" cycle. He has proven to be a true owner of his work and a highly reliable person. With time, Guy became the focal point in all the company's projects. Everyone knew that he was the one to consult. Guy is an exceptional individual. He is a great team player, and I enjoyed working with him. I only wish he would have stayed with us longer. However, I wish him good luck in his next role and good luck with the relocation to Boston. Sincerely, Shai Yosifon Chief of Engineering

To whom it may concern, With great pleasure, I am writing this letter of recommendation for Mr. Guy Roth, who held the Mechanical Engineer Team Leader position in our company, SMARTECH LTD. Since I have supervised him for the last five years, I can verify his strengths. Guy is a constant top performer in the operation group, a highly motivated, hardworking individual that brought his team employees to outstanding achievements. With a friendly personality and the ability to foster positive relationships with people he works with, he was very popular amongst his peers and supervisors. Guy held the mechanical engineer team leader position, where he managed the mechanical team, maintaining a high level of standards, mentoring the new teammates, leveraging best practices from other products, and problem-solving. All driven by curiosity, challenges & the desire to develop, with the ability to push and promote several topics simultaneously. During his time at SMARTECH, Guy traveled to customer sites, supported our sales representatives, and provided solutions when needed. I am confident that Guy will be an excellent addition to your company, especially where professionalism and good ethics are connected. If you need more information regarding his work profile, please feel free to contact me. Sincerely, Yair Stiller VP Operations Yair.stiller@smartech.com +972-54-6706500
