May 1, 2003


Mr. Gregory D. Perry
21 Cedar Avenue
Barrington, RI  02806

Dear Gregory:

It is with pleasure that we offer you the position of Vice President, Finance
and CFO, reporting to Michael J. Astrue, President and Chief Executive Officer.
Your gross bi-monthly pay rate will be $12,083.33, which equates to $290,000.00
gross per year. You will be paid in accordance with TKT's regular payroll
practices, currently the 15th and the last day of each month. All compensation
described in this letter, of course, be subject to all applicable federal, state
and local taxes and withholdings, and TKT pay policies.

Under the stock option plan and, subject to the approval of the Board of
Directors of the Company, the Company may grant to you the option to purchase
90,000 shares of TKT Common Stock. 18,000 options will vest immediately upon
your start date. The remaining options will vest equally over five years. The
exercise price of the stock will be determined at the close of business on the
last trading day before your official start date. The Option shall be subject to
all terms, vesting schedules, limitations, restrictions and termination
provisions set forth in a separate option agreement (which shall be based upon
TKT's standard form option agreement) that shall be executed to evidence the
grant of any option.

Should your employment with TKT be terminated without cause, you will be
eligible for severance pay of one (1) year of current base pay (less appropriate
withholdings and taxes).

You may participate in any and all benefit programs that TKT establishes and
makes available to its employees from time to time, provided you are eligible
under (and subject to all provisions of) the plan documents governing those
programs. TKT's benefits programs are subject to change by the Company without
notice. A summary of the current benefits is enclosed for your review.

As a condition of employment, you will be expected to sign the attached
Confidentiality, Inventions and Non-competition Agreement prior to joining TKT.
Please return both copies of this agreement to TKT along with your signed offer
letter. The agreement will be executed by TKT's Associate General Counsel, and
an original copy will be returned to you on your first day of employment. You
represent that you are not bound by any employment contract, restrictive
covenant or other restriction preventing you from entering into employment with
or carrying out your responsibilities for the Company, or which is in any way
inconsistent with the terms of this letter.

This offer of employment is contingent upon your being legally able to work in
the United States. Federal Law requires that you provide proof of employment
eligibility within three days of your employment. Should you accept our offer,
please be prepared to have the necessary documentation with you on your first
day of employment.

This letter shall not be construed as an agreement, either express or implied,
to employ you for the stated term, and shall in no way alter TKT's policy of
employment at will, under which both you and TKT remain free to end the
employment relationship, for any reason, at any time, with or without notice.
Similarly, nothing in this letter shall be construed as an agreement, either
express or implied, to pay you any compensation or grant you any benefit beyond
the end of your employment with TKT. TKT is free to change wages, benefits, work
location and conditions of employment at any time. This letter supersedes all
prior understandings, whether written or oral, relating to the terms of your
employment.

If you accept this offer of employment, please sign below and return one (1)
copy of this letter, along with both copies of your signed Confidentiality
agreement, to me in the enclosed envelope. The second original copy of this
letter is for your files.

This offer of employment will remain valid until May 10, 2003.

Greg, we sincerely hope that you will accept our offer of employment and join us
at TKT. We look forward to hearing from you by May 10, 2003. We are very excited
about the future growth of TKT and anticipate that you will complement our team
of innovative and dedicated professionals. Please let me know if there is
anything I can do to assist you in your decision-making process.

Sincerely,

/s/ Michael J. Astrue
