trusted advisor and resource to the Board and was a good friend to all of us.
Over the past ten years, Irv has given us the benefit of his considerable
accounting experience, business acumen and creativity. He was one of those
rare accounting professionals who seamlessly blended a command of accounting
principles and attention-to-detail with pragmatism. On the one hand, he never
missed a detail. On the other hand, he was invaluable at thinking through
solutions for the business.”

mentor and advisor to me since I arrived at the Company and I will miss him a
great deal.”
