From: Michael Chewens [MChewens@nbtbci.com] Sent: Tuesday, February 04, 2003 4:57 PM To: rulecomments@sec.gov Subject: File No. S7-50-02 Proposed amendments to Rule 10b-18 To Whom It May Concern: I am the Chief Financial Officer of NBT Bancorp Inc, (nbtb). I have never written to the SEC with my opinion on any subject before. However, as I continue to read about proposed amendments to Rule 10b-18 I am deeply concerned of the impact of the proposed changes on smaller companies like ourselves ($600 million in market cap). An important part of our financial strategy going forward is to reduce the number of NBTB outstanding shares. By eliminating the block exception to the current buyback limitations we are posed with two significant problems. First, given our normal volumes, including our very limited block trades, the 20 day average will limit our ability to make any significant purchases over a realistic time frame. Second, knowing that we are a buyer from time to time, who in essence will now be taken out of the market place for large purchases, will scare off or keep away potential large investors who will fear that we do not have enough liquidity or other institutional investors to allow for an orderly exit strategy out of our stock. There could also be a whole new level of price volatility added to our stock. The SEC's contention that we might somehow be helped or that the damage be limited by allowing block purchases to be counted towards the average is not true for our stock given the infrequency to which our stock is traded in blocks outside of our own buy backs. As for the proposed disclosure requirement, I believe if you require that Companies publicly announce any Board approved buy back program, including all of the parameters to which the Board approved it, then any further disclosure of the actual repurchase transactions occurring more frequently than quarterly would be overkill. Certainly to have to disclose every transaction would be an unnecessary burden. No one is going to feel safe trading outside of the current safe harbor rules so perhaps granting some relief for small to mid size cap companies would be in order. Please let me know if I am unclear. I would be happy to discuss this at any time. I can be reached at 607-337-6520.
