     Interleukin Genetics Reports Third Quarter Financial Results

    WALTHAM, Mass.--(BUSINESS WIRE)--Nov. 3, 2004--Interleukin
Genetics, Inc. (OTCBB: ILGN) a leader in the development of
personalized health products, today reported revenue of $1,400,000 and
a net loss of $373,000 or $0.02 per basic and diluted share, for the
quarter ended September 30, 2004.

    Financial Results:

    Revenue for the quarter was $1,400,000 compared to $634,000 in the
same quarter of 2003. The increase is primarily the result of $690,000
of revenue from a new research project on weight management with
Alticor entered into in June 2004. Both periods include $625,000 in
research funding related to the research agreement with Alticor
entered into in March 2003. For the quarter, the Company reported a
net loss of $373,000, or $0.02 per basic and diluted share, as
compared to a net loss of $767,000, or $0.03 per basic and diluted
share, for the same period last year.
    Research and development expenditures were $256,000 in the quarter
ended September 30, 2004 compared to $374,000 in the comparable
quarterly period ended September 30, 2003. The decrease in R&D
expenses reflects a re-allocation of internal resources from
internally-funded projects to the research projects funded by Alticor.
Those reallocated costs are now reported as cost of revenue.
    Selling, general and administrative expenses were $667,000 for the
quarter ended September 30, 2004 compared to $482,000 during the same
period last year. The increase is primarily the result of the Company
adding the appropriate infrastructure in its efforts to develop other
markets for its products and building a CLIA laboratory.
    As of September 30, 2004, the Company reported total assets of
$7,164,000, including $5,507,000 in cash and cash equivalents as
compared to total assets of $5,458,000 including $4,759,000 in cash
and cash equivalents as of December 31, 2003. The increase in cash
reflects the $2,000,000 milestone payment received from Alticor in
March 2004.
    For the nine months ended September 30, 2004, the Company reported
revenue of $2,709,000 and a net loss of $2,222,000 or $0.09 per share
compared to revenue of $1,295,000 and a net loss of $3,381,000 or
$0.15 per share for the same period last year.
