DIRECTOR ACCESS VARIABLE ANNUITY
HARTFORD LIFE AND ANNUITY INSURANCE COMPANY
SEPARATE ACCOUNT ONE
SUPPLEMENT DATED AUGUST 11, 1999
TO THE PROSPECTUS DATED MAY 3, 1999
Due to administrative error, under the section entitled "Other Information"
under the subheading "How Contracts Are Sold," the last paragraph was
erroneously included in the prospectus. The paragraph described circumstances
under which a Contract may be sold to employees of Hartford without payment of
sales compensation to a registered representative. The paragraph is not
applicable to the Contract described in the prospectus and is deleted.
Under the section entitled "Annuity Payouts" in the first paragraph under the
subheading "1. When do you want Annuity Payouts to begin?," the third sentence
is deleted and replaced with the following:
The Annuity Commencement Date cannot be deferred beyond the Annuitant's
90th birthday or the end of the 10th Contract Year, whichever is later
unless you elect a later date to begin receiving payments subject to
the laws and regulations then in effect and our approval.
