Reference is hereby made to Items 5-9 and 11 of pages 2-5
of this Schedule, which Items are incorporated by reference
herein.
Paul Stephens holds 300,000 shares of the Issuer's common
stock personally. The balance of shares reported as beneficially
owned by the reporting persons on this Schedule are held in
client accounts.
SIM, as general partner and investment manager of certain
client accounts, may be deemed to have the power to direct the
voting or disposition of the Issuer's common stock held by such
accounts. Therefore, SIM, as those accounts' general partner and
investment manager, and Paul Stephens, Brad Stephens and Bart
Stephens, as managing members and owners of SIM, may be deemed to
beneficially own the common stock owned by those accounts for the
purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as
amended, insofar as they may be deemed to have the power to
direct the voting or disposition of that common stock.
CUSIP No. 231269101 SCHEDULE 13G Page 8 of 11
Neither the filing of this Schedule nor any of its
contents shall be deemed to constitute an admission that SIM,
Paul Stephens, Brad Stephens or Bart Stephens is, for any other
purpose, the beneficial owner of any securities to which this
Schedule relates, and each of SIM, Paul Stephens, Brad Stephens
and Bart Stephens disclaims beneficial ownership as to those
securities, except to the extent of his or its pecuniary
interests therein. Neither the filing of this Schedule nor any
of its contents shall be deemed to constitute an admission that
any of the other individual general partners, directors,
executive officers, and members of SIM is, for any purpose, the
beneficial owner of any of the securities to which this Schedule
relates, and such beneficial ownership is expressly disclaimed.
The calculation of percentage of beneficial ownership in
item 11 of pages 2-5 was derived from the Issuer's Quarterly
Report on Form 10-Q filed with the Securities and Exchange
Commission on November 9, 2006, in which the Issuer stated that
the number of shares of common stock, $0.01 par value,
outstanding as of November 6, 2006 was 49,234,657.
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.
SIM serves as general partner and investment manager to
certain client accounts that have the right to receive or the
power to direct the receipt of dividends from, or the proceeds
from the sale of, the Issuer's common stock. Other than as
reported in this Schedule, no individual client's holdings exceed
five percent of that common stock.
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.
Not applicable.
CUSIP No. 231269101 SCHEDULE 13G Page 9 of 11
Item 10. Certifications.
By signing below I certify that, to the best of my
knowledge and belief, the securities referred to above were not
acquired and are not held for the purpose of or with the effect
of changing or influencing the control of the issuer of the
securities and were not acquired and are not held in connection
with or as a participant in any transaction having that purpose
or effect.
Signature
After reasonable inquiry and to the best of my knowledge
and belief, the undersigned certifies that the information set
