CUSIP 232808105 SCHEDULE 13G Page 5 of 7
Because Wentworth is a wholly owned subsidiary of
LNTC, it is possible that LNTC may be deemed a beneficial owner
of the Company's shares held by Wentworth by virtue the
definition of "Beneficail Ownership" in Rule 13d-3 under the
Securities Exchange Act of 1934. Although Wentworth and LNTC are
reporting such securities as if they were members of a group, the
filing of this Schedule shall not be construed as an admission by
LNTC that it is a beneficial owner of any securities of the
Company held by Wentworth.
In addition, it is possible that the individual
general partners, directors, executive officers, members, and/or
managers of Wentworth or LNTC might be deemed the "beneficial
owners" of some or all of the securities to which this Schedule
relates in that they might be deemed to share the power to direct
the voting or disposition of such securities. Neither the filing
of this Schedule nor any of its contents shall be deemed to
constitute an admission that any of such individuals is, for any
purpose, the beneficial owner of any of the securities to which
this Schedule relates, and such beneficial ownership is expressly
disclaimed.
Item 5. Ownership of Five Percent or Less of a Class.
Not applicable.
Item 6. Ownership of More Than Five Percent on Behalf of
Another Person.
Wentworth is deemed to be the beneficial owner of the
number of securities reflected in Items 5-9 and 11 of page two
(2) of this Amendment to Schedule 13G pursuant to separate
arrangements whereby Wentworth acts as investment adviser to
certain persons. Each person for whom the reporting person acts
as investment adviser has the right to receive or the power to
direct the receipt of dividends from, or the proceeds from the
sale of, the Common Stock purchased or held pursuant to such
arrangements.
Item 7. Identification and Classification of the Subsidiary
Which Acquired the Security Being Reported on by the
Parent Holding Company.
Not applicable.
Item 8. Identification and Classification of Members of the
Group.
Not applicable.
Item 9. Notice of Dissolution of Group.
