Item 5.  Other Events.

     On February 4, 1998, Pharmacopeia, Inc. ("Pharmacopeia") and Molecular
Simulations Incorporated ("MSI") announced the execution of a definitive merger
agreement (the "Merger Agreement") under which Pharmacopeia will acquire MSI in
a tax-free, stock-for-stock transaction to be accounted for on a pooling basis.
Pursuant to the Merger Agreement, Micro Acquisition Corporation, a wholly owned
subsidiary of Pharmacopeia, will be merged into MSI with MSI as the surviving
corporation.

     Pursuant to the Merger Agreement, Pharmacopeia will acquire all of the
outstanding stock of MSI for approximately 7.0 million newly-issued shares of
Pharmacopeia common stock.  Pharmacopeia will also convert the outstanding MSI
options into Pharmacopeia options, potentially resulting in the net issuance of
an additional 1.5 million new Pharmacopeia shares.

     The transaction is subject to certain conditions, including stockholder
approvals, the effectiveness of a registration statement under federal
securities laws relating to the Pharmacopeia common stock to be issued in the
merger, the listing of such Pharmacopeia common stock on the Nasdaq National
Market and the expiration of applicable waiting periods under pre-merger
notification regulations.

     The Merger Agreement and the press release issued in connection therewith
are filed as exhibits to this report and are incorporated herein by reference.
The description of the Merger Agreement set forth herein does not purport to be
complete and is qualified in its entirety by the provisions of the Merger
Agreement.  The shares of Pharmacopeia common stock will be offered to MSI
stockholders only through a prospectus forming part of a registration statement
that will be filed with the Securities and Exchange Commission.

Item 7.  Financial Statements and Exhibits.

          The following exhibits are filed herewith:

                         OF MERGER AND REORGANIZATION

     THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("Agreement") is made
and entered into as of February 4, 1998, by and among:  PHARMACOPEIA, INC., a
Delaware corporation ("Parent"); MICRO ACQUISITION CORPORATION, a Delaware
corporation and a wholly owned subsidiary of Parent ("Merger Sub"); and
MOLECULAR SIMULATIONS INCORPORATED, a Delaware corporation (the "Company").
Certain capitalized terms used in this Agreement are defined in Exhibit A.

                                    RECITALS

     A.  Parent, Merger Sub and the Company intend to effect a merger of Merger
Sub into the Company in accordance with this Agreement and the Delaware General
Corporation Law (the "Merger").  Upon consummation of the Merger, Merger Sub
will cease to exist, and the Company will become a wholly owned subsidiary of
Parent.

     B.  It is intended that the Merger qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code").  For accounting purposes, it is intended that the Merger
be treated as a "pooling of interests."

     C.  The respective boards of directors of Parent, Merger Sub and the
Company have approved this Agreement and the Merger.

                                   AGREEMENT

     The parties to this Agreement, intending to be legally bound, agree as
follows:

SECTION 1.  DESCRIPTION OF TRANSACTION

     1.1  MERGER OF MERGER SUB INTO THE COMPANY.    Upon the terms and subject
to the conditions set forth in this Agreement and in accordance with the
provisions of applicable law, at the Effective Time (as defined in Section 1.3),
Merger Sub shall be merged with and into the Company, and the separate existence
of Merger Sub shall cease.  The Company will continue as the surviving
corporation in the Merger (the "Surviving Corporation").

     1.2  EFFECT OF THE MERGER.    The Merger shall have the effects set forth
in this Agreement and in the applicable provisions of the Delaware General
Corporation Law (the "DGCL").

     1.3  CLOSING; EFFECTIVE TIME.    The consummation of the transactions
contemplated by this Agreement (the "Closing") shall take place at the offices
of Cooley Godward LLP, 4365 Executive Drive, Suite 1100, San Diego, California
92121-2128 or at such other place as the parties may agree, at 10:00 a.m. on a
date to be specified by the parties (the "Closing Date"), which (subject to the
satisfaction or waiver of the conditions set forth in Sections 6 and 7) shall be
no later than the second business day after satisfaction of the latest to occur
of the conditions set forth in Sections 6.4, 6.6, 6.8, 7.4, 7.6 and 7.8.
Contemporaneously with or as promptly as practicable after the Closing, a
properly executed certificate of merger conforming to the requirements of the
DGCL (the "Certificate of Merger") shall be filed with
<PAGE>
 
the Secretary of State of the State of Delaware.  The Merger shall take effect
at the time the Certificate of Merger is filed with the Secretary of State of
the State of Delaware (the "Effective Time").

     1.4  CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS.
Unless otherwise determined by Parent and the Company prior to the Effective
Time:

          (a) the Certificate of Incorporation of the Surviving Corporation
shall be amended and restated as of the Effective Time to conform to the
Certificate of Incorporation of Merger Sub in the form  filed with the Secretary
of State of the State of Delaware on January 9, 1998, except that the name of
the Surviving Corporation will be Molecular Simulations Incorporated;

          (b) the Bylaws of the Surviving Corporation shall be amended and
restated as of the Effective Time to conform to the Bylaws of Merger Sub as in
effect immediately prior to the Effective Time; and

          (c) the directors and officers of the Surviving Corporation
immediately after the Effective Time shall be the respective individuals who are
directors and officers of Merger Sub immediately prior to the Effective Time.

     1.5  CONVERSION OF SHARES.

          (a) Subject to Sections 1.5(c) and 1.8, at the Effective Time, by
virtue of the Merger and without any further action on the part of Parent,
Merger Sub, the Company or any stockholder of the Company:

          (i) any shares of Company Capital Stock then held by the Company or
any subsidiary of the Company (or held in the Company's treasury) shall be
canceled;

          (ii) any shares of Company Capital Stock then held by Parent, Merger
Sub or any other subsidiary of Parent shall be canceled;

          (iii) except as provided in clauses "(i)" and "(ii)" above and subject
to Section 1.5(b), each share of Company Capital Stock then outstanding shall be
converted into .5292 of a share of Parent Common Stock (as adjusted pursuant to
Section 1.5(b), the "Exchange Ratio") upon surrender of the certificate
representing such share of Company Capital Stock in the manner provided in
Section 1.7 (or in the case of a lost, stolen or destroyed certificate, upon
delivery of an affidavit in the manner provided in Section 1.7); and

          (iv) each share of the common stock, par value $.01 per share, of
Merger Sub then outstanding shall be converted into one share of common stock of
the Surviving Corporation.

          (b) Subject to Section 4.2, if, between the date of this Agreement and
the Effective Time, the outstanding shares of Company Capital Stock or Parent
Common Stock are changed into a different number or class of shares by reason of
any stock split, stock dividend, reverse stock split, reclassification,
recapitalization or other similar transaction, then the Exchange Ratio shall be
appropriately adjusted.

          (c) No fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and no certificates for any such fractional shares
shall be issued. In lieu of such fractional shares, any holder of Company
Capital Stock who would otherwise be entitled to receive a fraction of a share
of

                                      -2-
<PAGE>
 
Parent Common Stock (after aggregating all fractional shares of Parent Common
Stock issuable to such holder) shall, upon surrender of such holder's Company
Stock Certificate(s), be paid in cash the dollar amount (rounded to the nearest
whole cent), without interest, determined by multiplying such fraction by the
last reported bid price of a share of Parent Common Stock on the Nasdaq on the
date the Merger becomes effective.

     1.6  CLOSING OF THE COMPANY'S TRANSFER BOOKS.    At the Effective Time:
(a) all shares of Company Capital Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Capital
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as stockholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Capital Stock outstanding immediately prior to the Effective Time.  No further
transfer of any such shares of Company Capital Stock shall be made on such stock
transfer books after the Effective Time.  If, after the Effective Time, a valid
certificate previously representing any of such shares of Company Capital Stock
(a "Company Stock Certificate") is presented to the Exchange Agent (as defined
in Section 1.7) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.7.

     1.7  EXCHANGE OF CERTIFICATES.

          (a) Prior to the Closing Date, Parent shall select a reputable bank or
trust company to act as exchange agent in the Merger (the "Exchange Agent").
Promptly after the Effective Time, Parent shall deposit with the Exchange Agent
(i) certificates representing the shares of Parent Common Stock issuable
pursuant to this Section 1 and (ii) cash sufficient to make payments in lieu of
fractional shares in accordance with Section 1.5(c).  The shares of Parent
Common Stock and cash amounts so deposited with the Exchange Agent, together
with any dividends or distributions received by the Exchange Agent with respect
to such shares, are referred to collectively as the "Exchange Fund."

          (b) As soon as practicable after the Effective Time, the Exchange
Agent will mail to the holders of Company Stock Certificates (i) a letter of
transmittal in customary form and containing such provisions as Parent may
reasonably specify (including a provision confirming that delivery of Company
Stock Certificates shall be effected, and risk of loss and title to Company
Stock Certificates shall pass, only upon delivery of such Company Stock
Certificates to the Exchange Agent), and (ii) instructions for use in effecting
the surrender of Company Stock Certificates in exchange for certificates
representing Parent Common Stock.  Subject to Section 1.5(c), upon surrender of
a Company Stock Certificate to the Exchange Agent for exchange, together with a
duly executed letter of transmittal and such other documents as may be
reasonably required by the Exchange Agent or Parent, (1) the holder of such
Company Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of shares of Parent Common Stock that such
holder has the right to receive pursuant to the provisions of Section
1.5(a)(iii), and (2) the Company Stock Certificate so surrendered shall be
canceled.  Until surrendered as contemplated by this Section 1.7, each Company
Stock Certificate shall be deemed, from and after the Effective Time, to
represent only the right to receive shares of Parent Common Stock (and cash in
lieu of any fractional share of Parent Common Stock) as contemplated by this
Section 1.  If any Company Stock Certificate shall have been lost, stolen or
destroyed, Parent may, in its discretion and as a condition precedent to the
issuance of any certificate representing Parent Common Stock, require the owner
of such lost, stolen or destroyed Company Stock Certificate to provide an
appropriate affidavit  as indemnity against any claim that may be made against
the Exchange Agent, Parent or the Surviving Corporation with respect to such
Company Stock Certificate.  Neither Parent nor the Exchange Agent shall require
the owner of such lost, stolen or destroyed Company Stock Certificate to provide
a bond as
                                      -3-
<PAGE>
 
indemnity against any claim that may be made against the Exchange Agent, Parent
or the Surviving Corporation with respect to such Company Stock Certificate. In
the event of a transfer of ownership of Company Capital Stock which is not
registered in the transfer records of the Company, a certificate representing
the proper number of shares of Parent Common Stock may be issued to a transferee
if the certificate representing such Company Capital Stock is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer, and by evidence that any applicable stock transfer taxes have
been paid.

          (c) Any portion of the Exchange Fund that remains undistributed to
former stockholders of the Company six months after the date on which the Merger
becomes effective shall be delivered to Parent upon demand, and any former
stockholders of the Company who have not theretofore surrendered their Company
Stock Certificates in accordance with this Section 1.7 shall thereafter look
only to Parent for satisfaction of their claims for Parent Common Stock, cash in
lieu of fractional shares of Parent Common Stock and any dividends or
distributions with respect to Parent Common Stock.

          (d) Each of the Exchange Agent, Parent and the Surviving Corporation
shall be entitled to deduct and withhold from any consideration payable or
otherwise deliverable pursuant to this Agreement to any holder or former holder
of Company Capital Stock such amounts as may be required to be deducted or
withheld therefrom under the Code or under any provision of state, local or
foreign tax law.  To the extent such amounts are so deducted or withheld, such
amounts shall be treated for all purposes under this Agreement as having been
paid to the Person to whom such amounts would otherwise have been paid.

          (e) Neither Parent nor the Surviving Corporation shall be liable to
any holder or former holder of Company Common Stock for any shares of Parent
Common Stock (or dividends or distributions with respect thereto), or for any
cash amounts, delivered to any public official pursuant to any applicable
abandoned property, escheat or similar law.

     1.8  APPRAISAL RIGHTS.

          (a) Notwithstanding anything to the contrary contained in this
Agreement, Appraisal Shares (as defined in Section 1.8(c)) shall not be
converted into or represent the right to receive Parent Common Stock in
accordance with Section 1.5(a) (or cash in lieu of fractional shares in
accordance with Section 1.5(c)), and each holder of Appraisal Shares shall be
entitled only to such rights with respect to such Appraisal Shares as may be
granted to such holder in Section 262 of the DGCL.  From and after the Effective
Time, a holder of Appraisal Shares shall not have and shall not be entitled to
exercise any of the voting rights or other rights of a stockholder of the
Surviving Corporation.  If any holder of Appraisal Shares shall fail to perfect
or shall waive, rescind, withdraw or otherwise lose such holder's right of
appraisal under Section 262 of the DGCL, then (i) any right of such holder to
require the Company to purchase the Appraisal Shares for cash shall be
extinguished and (ii) such shares shall automatically be converted into and
shall represent only the right to receive (upon the surrender of the certificate
or certificates representing such shares) Parent Common Stock in accordance with
Section 1.5(a) (and cash in lieu of any fractional share in accordance with
Section 1.5(c)).

          (b) The Company (i) shall give Parent prompt written notice of any
demand by any stockholder of the Company for appraisal of such stockholder's
shares of Company Capital Stock pursuant to the DGCL and of any other notice,
demand or instrument delivered to the Company pursuant to the DGCL, and (ii)
shall give Parent's Representatives the opportunity to participate in all
negotiations and proceedings with respect to any such notice, demand or
instrument. The Company shall not make any

                                      -4-
<PAGE>
 
payment or settlement offer with respect to any such notice or demand unless
Parent shall have consented in writing to such payment or settlement offer.

          (c) For purposes of this Agreement, "Appraisal Shares" shall refer to
any shares of Company Capital Stock outstanding immediately prior to the
Effective Time that are held by stockholders who are entitled to demand and who
properly demand appraisal of such shares pursuant to, and who comply with the
applicable provisions of, Section 262 of the DGCL.

     1.9    TAX CONSEQUENCES.    For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code.  The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.

     1.10  ACCOUNTING CONSEQUENCES.    For accounting purposes, the Merger is
intended to be treated as a "pooling of interests."

     1.11  FURTHER ACTION.    If, at any time after the Effective Time, any
further action is determined by Parent to be necessary or desirable to carry out
the purposes of this Agreement or to vest the Surviving Corporation with full
right, title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

          (b) The Company Financial Statements present fairly, in all material
respects, the consolidated financial position of the Acquired Corporations as of
the respective dates thereof and the consolidated results of operations and cash
flows of the Acquired Corporations for the periods covered thereby.  The Company
Financial Statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
covered (except that the financial statements referred to in Section 2.4(a)(ii)
do not contain footnotes and are subject to normal and recurring year-end audit
adjustments, which will not, individually or in the aggregate, be material in
magnitude).

          (c) Except for liabilities or obligations which are accrued or
reserved in the Company Financial Statements (or reflected in the Notes thereto)
or which were incurred after September 30, 1997 in the ordinary course of
business, the Company has no liabilities or obligations (accrued or contingent)
of a nature required by GAAP to be reflected in a balance sheet or that would be
required to be disclosed in footnotes that would be required pursuant to Article
10 of Regulation S-X promulgated by the SEC in connection with the filing with
the SEC of a quarterly report on Form 10-Q.

          (d) Part 2.4(d) of the Company Disclosure Schedule is an aged list of
the Company's accounts receivable as of September 30, 1997.  The Company's

          (b) suffered any material loss, or material interruption in use, of
any asset or property (whether or not covered by insurance), on account of fire,
flood, riot, strike or other hazard or Act of God;

                                      -7-

     2.6  TITLE TO ASSETS; EQUIPMENT; REAL PROPERTY.    The Acquired
Corporations own, and have good, valid and marketable title to, the assets
purported to be owned by them and which are material to the Acquired
Corporations or to the conduct of their business.  Except as set forth in Part
2.6 of the Company Disclosure Schedule, such assets are owned by the Acquired
Corporations free and clear of any Encumbrances, except for (x) any lien for
current taxes not yet due and payable and (y) liens that have arisen in the
ordinary course of business and that do not materially detract from the value of
the assets subject thereto or materially impair the operations of the Acquired
Corporations.  The material items of equipment and other tangible assets owned
by or leased to the Acquired Corporations are adequate for the uses to which
they are being put and are in good condition and repair (ordinary wear and tear
excepted).  None of the Acquired Corporations owns or leases any real property
or any material interest in real property, except for the leaseholds created
under the real property leases included in Part 2.8 of the Company Disclosure
Schedule.

     2.7  PROPRIETARY ASSETS.

another Acquired Corporation any right (whether or not currently exercisable) to
sublicense, commercially distribute or otherwise market any Acquired Corporation
Proprietary Asset.

          (b) The Acquired Corporations have taken commercially reasonable
measures and precautions to protect and maintain the confidentiality, secrecy
and value of the Acquired Corporation Proprietary Assets (except Acquired
Corporation Proprietary Assets whose value would be unimpaired by public
disclosure). No current or former officer, director, stockholder, employee,
consultant or independent contractor has any ownership right with respect to any
Acquired Corporation Proprietary Asset.

          (c) To the Knowledge of the Company: (i) all patents, trademarks,
service marks and copyrights that are registered with any Governmental Body and
held by any of the Acquired Corporations are valid and subsisting; (ii) none of
the Acquired Corporation Proprietary Assets, the use thereof in the Acquired
Corporations' business activities or the conduct of the Acquired Corporations'
business as presently conducted infringes any Proprietary Asset owned or used by

Corporation Proprietary Asset.

          (d) The Acquired Corporation Proprietary Assets, together with
agreements for the license to an Acquired Corporation of software generally

Compliant.  For purposes of this Agreement, "Year 2000 Compliant" means that the
Acquired Corporation Proprietary Assets which have an internal calendar or a
requirement to manipulate, store, compare or sequence dates (i) will accurately
manage, manipulate, input, accept, process, store and output dates up to,
including and following January 1, 2000 without adversely affecting the
operability of the Acquired Corporation Proprietary Assets or the utility of the
data produced therefrom and (ii) will accurately process date/time data from the
year 1999 into the year 2000.

          (g) Part 2.7(g) of the Company Disclosure Schedule sets forth all
patents that have been issued to an Acquired Corporation, patent applications
that have been filed by an Acquired Corporation and trademarks that have been
registered by an Acquired Corporation and the jurisdictions in which such
patents have been issued, patent applications have been filed and trademarks
have been registered.

          (h) With respect to the in-license agreements identified in Part
2.7(h) of the Company Disclosure Schedule and the software licensed to an
Acquired Corporation pursuant thereto (the "Identified In-License Software"),
such in-license agreements provide an Acquired Corporation with sufficient
rights for such Acquired Corporation to license to its customers for their use
the Acquired Corporation's current commercially released products that
incorporate the Identified In-License Software.

     2.9  COMPLIANCE WITH LEGAL REQUIREMENTS.    Each of the Acquired

Governmental Authorizations necessary to enable the Acquired Corporations to
conduct their respective businesses in the manner in which such businesses are
currently being conducted and in compliance with applicable Legal Requirements,
except where failure to hold such Governmental Authorizations will not have a
Material Adverse Effect on the Acquired Corporations.  Such Governmental
Authorizations are valid and in full force and effect.  Each Acquired
Corporation is in compliance with the terms and requirements of such
Governmental Authorizations except where failure to be in compliance will not
have a Material Adverse Effect on the Acquired Corporations.  None of the

applicable due date (including any extensions of such due date) and (ii) have
been, or will be when filed, prepared in compliance with applicable Legal

or closing agreement with a Governmental Body that has continuing effect.

          (e) There is no agreement, plan, arrangement or other Contract

permits and other material Governmental Authorizations required under applicable
Environmental Laws, and Parent and its subsidiaries are and have been in
compliance with the terms and requirements of all such Governmental
Authorizations, except for failures to be in compliance that would not
reasonably be expected to have a Material Adverse Effect on Parent.  Neither
Parent nor any of its subsidiaries has received or given, and to the Knowledge
of Parent, no current or prior owner of any property leased or controlled by
Parent or any of its subsidiaries has received or given any notice, citation,
summons, order, complaint, penalty, assessment, request for information, demand
or other communication (in writing) to or from any Governmental Body or other
Person regarding any actual, alleged, possible or potential material liability
or responsibility arising from or relating to the presence, generation,
manufacture, production, transportation, importation, use, treatment,
refinement, processing, handling, storage, discharge, release, emission or
disposal of any Material of Environmental Concern that has not already been paid

regarding any actual or possible (a) cancellation or invalidation of any
insurance policy, (b) refusal of any coverage or rejection of any material claim

Stock.

Except as contemplated by this Agreement or as may be required by the DGCL,
federal and state securities laws, the By-laws of the National Association of
Securities Dealers or under the HSR Act, neither Parent nor Merger Sub is or
will be required to make any filing with or give any notice to, or to obtain any

               PHARMACOPEIA, INC. ANNOUNCES AGREEMENT TO ACQUIRE
                          MOLECULAR SIMULATIONS INC.

   -COMBINATION WILL CREATE UNIQUE PLATFORM FOR ACCELERATED DRUG DISCOVERY-
                                        
Princeton, NJ, and San Diego, CA, February 4, 1998  Pharmacopeia, Inc., (Nasdaq:
PCOP) and Molecular Simulations Inc. (MSI) today announced that they have signed
a definitive agreement pursuant to which Pharmacopeia will acquire all of the
outstanding stock of MSI for approximately 7.0 million newly-issued shares of
Pharmacopeia common stock.  Pharmacopeia will also convert the outstanding MSI
options into Pharmacopeia options, potentially resulting in the net issuance of
an additional 1.5 million new Pharmacopeia shares.  Based on the $16.50 per
share closing price of Pharmacopeia common stock on February 3, 1998, the
transaction is valued at approximately $140 million.  The agreement has been
approved by the Boards of Directors of both companies but remains subject to
customary closing conditions, including regulatory approval and approval by the
stockholders of both companies.  The transaction is expected to close during the
second quarter of 1998.

MSI is a San Diego, California-based provider of predictive modeling software
and services for both life and materials science research.  MSI's products
enable scientists to simulate chemical behavior at the molecular level by
modeling structures and properties of molecular systems.  These products are
used by scientists in R&D laboratories worldwide to enhance the speed and
efficiency of the R&D process by reducing overall costs, decreasing product lead
times, and accelerating time to market.  MSI has recently implemented a Web-
based architecture, which will expand the availability of MSI software products
and libraries to any scientist using a Web browser on a desktop computer.  MSI
has over 3,500 installed sites in commercial, academic and governmental research
and development laboratories with approximately 10,000 users.

"Combining these two industry leaders provides great opportunity to our
customers, employees and stockholders," said Joseph A. Mollica, Pharmacopeia's
Chairman, President and Chief Executive Officer.  "Each company's strengths
complement the other.  We believe that Pharmacopeia's ability to design and
synthesize large, rationally-designed libraries that expedite the drug discovery
process will be further refined by MSI's molecular design and analysis tools.
Our scientists will be able to work closely with MSI's scientists to more
tightly integrate computational, combinatorial and experimental chemistry.
These complementary strengths combined with MSI's emerging Web-based
applications will help position us to take drug discovery to a new level."

"The power of the combined company," continued Dr. Mollica, "lies in MSI's
ability to develop software to access the wealth of data inherent in
Pharmacopeia's large and growing database of structure-activity relationships.
This information will be used to validate existing design tools and to develop
new capabilities for use by Pharmacopeia, MSI and each company's respective
customers.  We have enormous respect for MSI, its employees and customers and
look forward to achieving further success together."

"MSI is pleased to join forces with a pioneer such as Pharmacopeia," said
Michael J. Savage, MSI's President and Chief Executive Officer.  "The ability to
directly apply our technology in Pharmacopeia's drug design process will enable
us to further enhance our portfolio of scientific simulation software.  By
enhancing our products, we would be able to offer more value to our current and
prospective customers and improve Pharmacopeia's ability to achieve further
success on behalf of their customers and within their internal programs.  In
addition, by combining the two companies, we significantly expand the scope of
products and services we can now offer to our more than 10,000 users, including
most major pharmaceutical and chemical companies.  The strengths of the combined
operations provide powerful new opportunities for both companies."

Upon completion of the transaction, which will be structured as a tax-free
stock-for-stock exchange and accounted for as a pooling of interests, MSI will
become a wholly-owned subsidiary of Pharmacopeia.  Michael Savage, MSI's
President and Chief Executive Officer, will remain President of MSI and will
report directly to Joseph Mollica, Pharmacopeia's Chairman, President and CEO.
Mr. Savage and one other MSI Board member will be added to Pharmacopeia's Board
of Directors.

Goldman, Sachs & Co. provided financial advice to MSI.

Pharmacopeia, Inc. is a leader in drug discovery combining small molecule
combinatorial chemistry with high throughput screening.  Using ECLiPS, its
proprietary tagging technology, Pharmacopeia generates large libraries, now
consisting of 3.7 million diverse, easily identifiable, small molecules. Using
state-of-the-art high throughput screening, Pharmacopeia tests its compounds in
a full complement of assays, including enzyme, receptor binding and cell-based
assays.  Pharmacopeia is using its libraries and screening capabilities to
develop three potential profit centers: 1) the licensing of libraries to
pharmaceutical companies for evaluation in multiple drug discovery programs, 2)
the identification and optimization of lead compounds for specific targets
provided by customers, and 3) the licensing to pharmaceutical companies of drug
development candidates developed in Pharmacopeia's internal drug discovery
programs. Pharmacopeia currently has collaborative agreements with Akzo Nobel/NV
Organon, Bayer Corp., Berlex Laboratories, Bristol-Myers Squibb, Daiichi,
Novartis, Schering-Plough, and Zeneca.  Pharmacopeia also has a research
partnership with Regeneron Pharmaceuticals and research arrangements with
several biotechnology companies and academic and government laboratories.
