The Board of Directors
c/o Marshall M. Sloane
Chairman of the Board
Century Bancorp, Inc.
400 Mystic Avenue
Medford, MA  02155

Dear Members of the Board of Directors;

I am writing to respond to Marshall Sloane's puzzling remarks in his recent
interview with SNL Financial and to Paul Cusick's written response to our letter
of September 15, 2005.

Mr. Cusick's invitation to submit written suggestions directly to him sounds
shareholder-friendly, but history shows this approach to be anything but the
case. Secondly, we find ludicrous the claim that our letter is a repeat of our
June letter to the Board. New issues raised in our second letter included a
discussion of second quarter results, questions about your recent buyback
announcement, comments about other large shareholders writing to management to
agree with us, and our relating specific conversations with larger banks that
would like to speak to the Board about a potential merger.

In case you are not aware of the SNL interview published on September 16th,
Marshall Sloane responded to our questions and comments by lashing out at me
personally without directly addressing our concerns. His comments included that
I'm "certainly not familiar with the yield curve today that all banks are
facing." Further disparaging and dismissing our views he said, "If he had
something to say that was intelligent maybe we would listen to him." He also
said that "this guy is just looking for a quick fix" and that I "don't know
anything about our bank and anything about our community." Finally, he declined
my invitation to meet, which is peculiar as I never requested such a meeting
with him. We have no desire to meet with him. He and his sons are the very
management team that has caused the problems that Century now faces. We wish to
meet with the independent Board members -- the people who represent us. Was
Marshall Sloane authorized to speak for the Board in response to our letter or
was he RSVPing to a party to which he was not invited? And authorized or not, is
his insult-riddled non-answer to our questions the face that Century's Board
wishes to present to its public shareholders?

Marshall Sloane responded to our financial questions by saying that the flat
yield curve is causing many of the bank's current woes. Despite the fact that I
am "certainly not familiar with the yield curve today" I know enough to
understand that all banks are dealing with the same yield curve. Century's peers
faced the same flattening yield curve yet 96% of them posted better results than
Century, as measured by ROE. His defense of Century's performance, while not
addressing our questions and concerns, bizarrely makes reference to how Century
paid its dividend when at least one other peer (Bank of Boston) suspended its
own dividend. We would point out that this occurred in the early 1990s, and we
own the stock in 2005. I'm proud of all sorts of things that I did in the early
1990s but I would never use them as a defense for poor performance today. My
clients deserve better answers than that, as do Century's shareholders.

As to not knowing anything about your bank I think you'll agree that our
previous letters include a sobering and concise analysis of Century's current
under-performance. You'll also note that while I may not live in your community
my partner in this shareholder group, Paul Magidson, does. In addition, he spent
five years as a lender at one of your local competitors, BayBank, so we know far
more about your bank and community than the "nothing" that Marshall Sloane
contends. As Robert Reich famously said, "There are those who don't know and
those who don't know they don't know."

Finally, as to my looking to make a quick buck, if Marshall Sloane had bothered
to learn before speaking he'd know that my business revolves around making a
slow, methodical long-term buck. I offer as example and reference my previous
foray into shareholder activism at Provident Financial Holdings, a $1.6 billion
Riverside, CA bank on whose board I served from 2002 thru 2004. I have been a
shareholder of Provident for the 11 years that I have been in business and that
they have been publicly traded. Feel free to call the Chairman and CEO of
Provident, Craig Blunden at 951-782-6188 as a character witness.

As to being open to shareholders' constructive suggestions, according to a
letter sent to Marshall Sloane on June 13, 2005 by Endicott Management (a
long-time shareholder which owns 11% of Century Bank's Class A shares) and made
public by you in an SEC filing, Endicott provided a detailed analysis to Century
Bank's senior management, including the Sloanes and Mr. Cusick. The conclusion
of this analysis was that due to the backwards momentum of earnings growth
shareholders were better off if the company sought to maximize value in the
merger market. Clearly this advice has not been followed. Furthermore, even on a
path of independence, Endicott expressed frustration that Century management
would not respond to their analysis with any objective financial targets by
which the progress (or lack thereof) of the management team could be measured.
In a May 2, 2005, meeting with myself and Paul Magidson, Paul Cusick of your
bank also declined to offer any objective means by which investors might judge
Century's progress. I can assure you that most publicly-traded bank managements
are willing to offer (many unsolicited) ROA, ROE, and efficiency targets with a
firm timeframe so that investors might actually be able to hold them
accountable.

In our last letter, we made reference to an opinion published by Gerard Cassidy
of RBC Capital Markets. He believes that the stock is worth $20 based on its
current earnings power. Subsequent to that note, FIG Partners, another
independent research firm that specializes in financial stocks, weighed in with
its own comments about Century Bank. FIG referenced a Wall Street Journal
article in which Jack Welch observed that the first stage in crisis management
is usually denial. They see Century as being in denial given its refusal to meet
with us to discuss the company's poor operating results relative to its high
private market value. They also write that we have "raised real and fair
questions about Century's operations and outlook." As a growing number of
Century's shareholders (Endicott, Athena Capital Management), and now two
independent analysts, see things as we do, we would love for the Board to
explain how it sees things differently.

Finally, we pointed out in our last letter that we have had conversations with
another bank CEO who believes that Century is worth far more in a transaction
than the current share price and would like the opportunity to discuss this
further. We cannot imagine that there is no interest by the Board in doing so.
We would hope that the Board would wish to learn more about our conversations
with potential partners that are eager to express such sentiments to the Board.

In closing, we again call on the independent Board members to meet with us to
discuss the above issues. We continue to seek a meeting because we have not
received a response to the concerns that we raised in either our first or second
letter. All we received were vague statements that independence was the best
course of action, with no explanation of why that is true. There was no
rationalization as to why the economic value being created exceeds that which
could be realized in a sale. We will keep asking these questions until you give
us answers. The ostrich-head-in-the-sand denial defense is no way to build
long-term shareholder value.

We will soon file a 13D statement with the Securities and Exchange Commission
with this letter attached. We look forward to your response in regard to
accommodating our request for a meeting with the independent directors.

Sincerely,




Sy Jacobs
