Dear Mr. Kosoff:

Please be advised that Registrants have filed the above-referenced registration
statements ("Registration Statements") with the Securities and Exchange
Commission as initial filings on August 26, 2010 in Accession Nos.
0001104659-10-045485 and 0001104659-10-045486, respectively. A copy of the
Registration Statement's prospectus, redlined to show the changes from a
currently effective prospectus in another Hartford registration statement on
Form N-4 (File No. 333-148564) is being forwarded to you via electronic mail.

The initial Registration Statement filings are for flexible premium variable
annuity contracts. The new offering is based on the same state-filed contract
and are substantially identical to the prospectus in File No. 333-148564, except
for the addition of the "L" share class, an increase in Mortality & Expense
charge for the "C" share class and the removal of the Return of Premium I death
benefit.

All financial statements, exhibits, and other required disclosure not included
in this Registration Statement will be filed by amendment.

We appreciate your attention to this filing. If you have any comments or
questions, please call at (860) 843-1941.

Very truly yours,

/s/ Richard J. Wirth
