Memory Pharmaceuticals Refocuses to Advance Development and Clinical Programs

Expands PDE10 Collaboration with Amgen

Company to Host Conference Call at 9:00 A.M. EDT

MONTVALE, N.J., March 12 (HSMN NewsFeed) -- Memory Pharmaceuticals Corp. (Nasdaq: MEMY ) today announced that it has realigned its operations, reallocated its resources and extended the preclinical research portion of its PDE10 collaboration with Amgen. The Company will focus its near-term and mid- term efforts on two partnered programs, its nicotinic alpha-7 receptor agonist collaboration with Roche and the PDE10 collaboration with Amgen, and two proprietary programs, its PDE4 inhibitor and 5-HT6 antagonist programs.

"After conducting a thorough review of our pipeline, opportunities and financial resources, we have decided to focus on those areas where we can most optimally apply our expertise to create significant clinical and shareholder value," stated Vaughn M. Kailian, President and Chief Executive Officer of Memory Pharmaceuticals. "Consequently, we have reduced our discovery research effort in favor of progressing our four major programs."

In connection with this new operational focus, the Company implemented the following initiatives.

-- Reallocation of Resources. Memory Pharmaceuticals has realigned its
workforce to support its key development and clinical programs. The
Company has reduced its overall efforts dedicated to discovery
research, while maintaining its capabilities in CNS drug discovery to
support long-term growth. The Company's overall headcount has been
reduced by 20% and the Company has shifted its resources toward
development activities. The new structure will support the Company's
preclinical and clinical activities and business development

-- Focus on Key Development Activities. The Company plans to dedicate the
majority of its resources and investments to support continued
development of key partnered and proprietary programs:

-- Nicotinic Alpha-7 Receptor Agonist Collaboration with Roche. MEM
3454, the lead compound in the Company's nicotinic alpha-7 receptor
agonist collaboration with Roche, demonstrated a statistically
significant effect on multiple measures of cognition in a recent
Phase 2a study in Alzheimer's disease. Memory Pharmaceuticals is
currently evaluating the compound as a treatment for cognitive
impairment associated with schizophrenia (CIAS) in a Phase 2a trial
and expects to report top-line data from that trial in the fourth
quarter of 2008. In addition, the Company expects to initiate a
biomarker study for MEM 3454 in schizophrenia this summer, with
results expected by early 2009. The biomarker study will be funded
by Roche.

-- Memory Pharmaceuticals also expects to complete its Phase 1 program
for MEM 63908 and report top-line results in the fourth quarter of

-- PDE10 Inhibitor Collaboration with Amgen. The Company has amended
its collaboration with Amgen focused on the development of PDE10
inhibitors for certain neurological and psychiatric disorders.
Memory Pharmaceuticals has agreed to commit and fund certain
preclinical research resources and provide increased access to its
screening technologies to the collaboration over the next twelve
months. In exchange, Memory Pharmaceuticals will receive increased
milestone payments upon the achievement of certain predefined
development events for the program. In addition, the parties
expanded the scope of compounds eligible for higher tier royalties
under the agreement.

-- PDE4 inhibitor Program. The Company's PDE4 inhibitor program
includes MEM 1414, along with MEM 1917 and several backup compounds.
The Company believes that PDE4 inhibitors could be beneficial in
treating a number of cognition-related CNS disorders and
inflammatory diseases. MEM 1414 has demonstrated efficacy in a
broad range of preclinical cognition and anti-inflammatory models.
In addition, Phase 1 studies have demonstrated a favorable safety
profile for the compound overall and particularly with respect to
nausea and vomiting, which has limited the development of other PDE4
compounds. The Company plans to progress MEM 1414 into a Phase 2a
trial by the end of 2008.

-- 5-HT6 Antagonist Program. 5-HT6 antagonists are potential
treatments for Alzheimer's disease, schizophrenia, attention deficit
disorder and obesity. Memory Pharmaceuticals has generated a
portfolio of novel, potent and selective 5-HT6 antagonists and is
evaluating several lead compounds as potential development
candidates. The Company plans to advance the program into clinical
trials by the end of 2008.
