                                  RISK FACTORS

         In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
shares of Common Stock offered by this Prospectus.

         Early Stage of Product Development.  All of the Company's therapeutic
products are in various stages of research and development, and no revenues
have been generated from the commercialization of those products.  The Company
currently sells products to the laboratory reagent and medical diagnostic
markets.  The Company's therapeutic and new diagnostic products will require
substantial additional development, including in the areas of preclinical and
clinical testing, regulatory approvals and manufacturing processes prior to
their commercialization.  There can be no assurance that any of the Company's
therapeutic and diagnostic products which are under development will prove to
be safe or effective in clinical trials, will be approved by regulatory
authorities, can be manufactured at acceptable cost with appropriate quality,
or can be successfully marketed.

         History of Losses; Uncertainty of Future Profitability.  The Company
has incurred operating losses since its inception and had accumulated net
losses of approximately $43.1 million as of June 30, 1995.  The continued
development of the Company's products will require the commitment of
substantial resources to conduct research and preclinical and clinical
programs, to establish manufacturing capabilities and sales and marketing
capabilities, and to establish additional quality control, regulatory and
administrative capabilities.  The Company may incur substantial and increasing
operating losses over the next several years as its product development
programs and clinical testing expand.  The amount of net losses and the time
required by the Company to reach sustained profitability are highly uncertain
and to achieve profitability the Company must, among other things, successfully
complete development of its products, obtain regulatory approvals and establish
manufacturing and marketing capabilities.  There can be no assurance that the
Company will be able to achieve profitability at all or on a sustained basis.

         Need for Additional Funds.  The Company has funded its operations and
capital expenditures to date primarily through equity financing, strategic
alliances with commercial partners, and sales of reagent and diagnostic
products.  Since inception, the Company has raised proceeds, net of expenses, of
approximately $57 million through equity financings.  The Company anticipates
that it will need to raise substantial additional funds, through additional
equity or debt financings, research and development financings, collaborative
relationships or otherwise, prior to the commercialization of its products.
There can be no assurance that any such additional funding will be available to
the Company or, if available, that it will be on reasonable terms.  Any such
additional funding may result in significant dilution to existing stockholders.
If adequate funds are not available, the Company may be required to
significantly curtail its research and development programs or obtain funds
through arrangements with collaborative partners that may require the Company
to relinquish certain material rights to its products.

         Dependence on Third Parties for Clinical Supplies.  The Company is
dependent on its former commercial partner, SmithKline Beecham p.l.c., to
produce quantities of its first therapeutic product candidate, sCR1, suitable
for Phase II clinical trials, and is dependent on sourcing from a third party
manufacturer for additional suitable quantities of sCR1 for additional clinical
trials.  There can be no assurance at this time that the Company will be able
to utilize any of the material produced by its former partner or new
manufacturing source in the clinical trials.  The inability to have suitable
quality and quantities of material produced would result in significant delays
in the clinical development of sCR1.

         No Assurance of FDA Approval; Comprehensive Government Regulation.
The Company's research, development and clinical programs, as well as its
manufacturing and marketing operations, are subject to extensive regulation by
numerous governmental authorities in the United States and other countries.
Most of the Company's products require governmental approvals for
commercialization which have not yet been obtained and are not expected to be
obtained for several years.  Preclinical and clinical trials and manufacturing
and marketing of many of the Company's products will be subject to the rigorous
testing and approval processes of the FDA and corresponding foreign regulatory
authorities.  The regulatory process, which includes preclinical, clinical and
post-clinical testing of many of the Company's products to establish their
safety and efficacy, can take many years and requires the expenditure of
substantial resources.  Data obtained from preclinical and clinical activities
are susceptible to varying interpretations which could delay, limit or prevent
regulatory approval.  In addition, delays or rejection may be





                                       3

<PAGE>   6
encountered based upon changes in, or additions to, regulatory policies for
drug approval during the period of product development and regulatory review.
Delays in obtaining such approvals could adversely affect the marketing of
products developed by the Company and the Company's ability to generate
commercial product revenues.  There can be no assurance that requisite
regulatory approvals will be obtained within a reasonable period of time, if at
all.  Moreover, if regulatory approval of a product is granted, such approval
may impose limitations on the indicated uses for which such product may be
marketed.  Further, even if such regulatory approval is obtained, a marketed
product, its manufacturer and its manufacturing facilities are subject to
continual review and periodic inspections, and later discovery of previously
unknown problems with a product, manufacturer or facility may result in
restrictions on such product or manufacturer, including withdrawal of the
product from the market.  Failure to comply with the applicable regulatory
requirements can, among other things, result in fines, suspensions of
regulatory approvals, product recalls, operating restrictions and criminal
prosecution.

         Lack of Commercial Manufacturing Capability. To be successful, the
Company's diagnostic and therapeutic products must be manufactured in
commercial quantities, within regulatory requirements and at competitive costs.
The Company's experience in commercial manufacturing is limited to the
manufacturing of certain reagents and medical diagnostic test kits and there
can be no assurance that the Company will be able to successfully continue to
scale-up its diagnostic manufacturing operations to meet future market demands
or to obtain access to suitable therapeutic manufacturing facilities.

         Lack of Commercial Sales and Marketing Experience.  Except for
research reagents and certain diagnostic products, the Company has limited
experience in sales, marketing and distribution of commercial products.  To
market any of its products directly, the Company must develop a substantial
marketing and sales force with technical expertise and a supporting
distribution capability.  Alternatively, the Company may seek to obtain the
assistance of a strategic partner with the necessary sales and distribution
capabilities and expertise.  There can be no assurance that the Company will be
able to establish sales and distribution capabilities without undue delays or
expenditures or that it will be successful in gaining market acceptance for its
products.

         Competition and Risk of Technological Obsolescence.  Biotechnology,
pharmaceuticals and medical diagnostics are rapidly evolving fields in which
developments are expected to continue at a rapid pace.  Competitors of the
Company in the United States and abroad are numerous and include, among others,
pharmaceuticals, medical diagnostics, biotechnology companies, universities and
other research institutions.  The Company's success depends upon developing and
maintaining a competitive position in the development of products and
technologies in its area of focus.  Competition from other biotechnology,
pharmaceuticals and medical diagnostics companies is intense and expected to
increase as new products enter the market and new technologies become
available.  The Company's competitors may also succeed in developing
technologies and products that are more effective than any which have been or
are being developed by the Company or that render the Company's technologies or
products obsolete or noncompetitive.  The Company's competitors may also
succeed in obtaining patent protection or other intellectual property rights
that would block the Company's ability to develop its potential products, or in
obtaining regulatory approval for the commercialization of their products more
rapidly or effectively than the Company.  Finally, many of these competitors
have substantially greater research and development capabilities, clinical,
manufacturing, regulatory and marketing experience and financial and managerial
resources than the Company.

         Dependence on Patents and Proprietary Technology.  The biotechnology,
medical diagnostics and pharmaceutical industries place considerable importance
on the Company's obtaining patent and trade secret protection for new
technologies, products and processes, and the Company's success will depend, in
part, on its ability to obtain patent protection for its products and
manufacturing processes, preserve its trade secrets and operate without
infringing the proprietary rights of third parties.  In addition to the
Company's own patents and patent applications, a number of institutions have
exclusively licensed rights to certain patents and patent applications to the
Company.

         The Company is conducting research and expects to seek additional
patents in the future, but there can be no assurance as to its success or the
timeliness in obtaining any such patents or as to the breadth or degree of
protection which any such patents will afford the Company or not be challenged,
invalidated or infringed.  Furthermore, there can be no assurance that others
will not independently develop similar products and processes, duplicate any of
the Company's products or, if patents are issued to the Company, design around
such patents.  In





                                       4

<PAGE>   7
addition, the Company could incur substantial costs in defending itself in
suits brought against it or in suits in which the Company may assert its
patents against others.  If the outcome of any such litigation is adverse to
the Company, the Company's business could be adversely affected.

         In addition, the Company may be required to obtain licenses to patents
or other proprietary rights of third parties.  No assurance can be given that
any licenses required under any such patents or proprietary rights would be
made available on terms acceptable to the Company, if at all.  If the Company
does not obtain such licenses, it could encounter delays in product market
introductions while it attempts to design around such patents or other rights,
or be unable to develop, manufacture or sell such products.

         The Company also seeks to protect its proprietary technology,
including technology which may not be patented or patentable, in part by
confidentiality agreements and, if applicable, inventors' rights agreements
with its collaborators, advisors, employees and consultants.  There can be no
assurance that these agreements will not be breached, that the Company will
have adequate remedies for any breach, or that the Company's trade secrets will
not otherwise be disclosed to, or discovered by, competitors.  Moreover, the
Company conducts a significant amount of research through academic advisors and
collaborators who are prohibited from entering into confidentiality or
inventors' rights agreements by their academic institutions.

         Dependence on Reimbursement.  In both the United States and elsewhere,
sales of most of the Company's products, if any, will be dependent in part on
the availability of reimbursement from third party payors, such as government
and private insurance plans.  Third party payors are increasingly challenging
the prices charged for medical products and services.  Moreover, the federal
government of the United States has made the containment of health care costs a
top priority.  If the Company succeeds in bringing one or more products to
market, there can be no assurance that these products will be considered
cost-effective, that reimbursement will be available or, if available, that the
level of reimbursement will be sufficient to allow the Company to sell its
products on a profitable basis.

         Exposure to Product Liability Claims.  The Company's business exposes
it to potential product liability claims which are inherent in the testing,
manufacturing, marketing and sale of human therapeutic products.  The Company
currently has liability insurance of limited coverage.  There can be no
assurance that it will be able to maintain such insurance or obtain general
product liability insurance on acceptable terms or at reasonable costs or that
such insurance will be in sufficient amounts to provide the Company with
adequate coverage against potential liabilities.

         Dependence Upon Key Personnel.  The Company is dependent on the
members of its management and scientific staff, the loss of one or more of whom
could have a material adverse effect on the Company.  The Company also depends
on its scientific collaborators and advisors, all of whom have commitments that
may limit their availability to the Company.  In addition, the Company believes
that its future success will depend in large part upon its ability to attract
and retain highly skilled scientific, managerial and marketing personnel,
particularly as the Company expands its activities in clinical trials, the
regulatory approval process and sales and manufacturing.  The Company faces
significant competition for such personnel and from other companies, research
and academic institutions, government entities and other organizations.  There
can be no assurance that the Company will be successful in hiring or retaining
the personnel it requires for continued growth.  The failure to hire and retain
such personnel could materially and adversely affect the Company's prospects.

         Shares Eligible for Future Sale.  Future sales of Common Stock in the
public market by existing stockholders could have an adverse effect on the
price of the Common Stock.  In addition, the Company has registered the shares
of Common Stock issued under its Amended and Restated 1991 Stock Compensation
Plan and approximately 2.3 million shares of Common Stock are presently
eligible for sale upon exercise of currently outstanding options.

         Volatility of Stock Price.  The market price of the shares of Common
Stock, like that of the common stock of many other early-stage biotechnology
companies, may be highly volatile.  Factors such as announcements of
technological innovations or new commercial products by the Company or its
competitors, disclosure of results of clinical testing or regulatory
proceedings, governmental regulation and approvals, developments in patent or
other proprietary rights, public concern as to the safety of products developed
by the Company and general market conditions may have a significant effect on
the market price of the Common Stock.  In addition, the stock market has





                                       5

<PAGE>   8
experienced and continues to experience extreme price and volume fluctuations
which have effected the market price of many biotechnology companies and which
have often been unrelated to the operating performance of these companies.
These broad market fluctuations, as well as general economic and political
conditions, may adversely effect the market price of Common Stock.

                                  THE COMPANY

         T Cell Sciences, Inc. ("T Cell Sciences" or "TCS" or the "Company") is
an emerging biopharmaceutical company developing treatments for diseases caused
by misregulation of the body's natural defense systems.  TCS is developing
products for diseases of inflammation, and autoimmunity.  TCS has completed a
Phase I clinical trial of its first complement inhibitor therapeutic, sCR1, in
patients at risk of developing adult respiratory distress syndrome ("ARDS") and
is conducting a second Phase I trial for reperfusion injury following a heart
attack.  TCS, with its partner AB Astra ("Astra"), is also developing products
based on the T Cell antigen receptor for the treatment of autoimmune diseases.
The initial product candidates being developed with Astra are now in the
research and preclinical stage of development.  T Cell Sciences' wholly owned
subsidiary, T Cell Diagnostics, Inc. ("T Cell Diagnostics" or "TCD") is
developing, manufacturing and marketing new classes of diagnostic products to
be used for the detection and monitoring of immune-related disorders such as
organ transplant rejection, autoimmune conditions and cancers and infections
such as HIV.  TCD recently received marketing clearance from the U.S. Food and
Drug Administration ("FDA") to market TRAx(R) CD4 for CD4 T cell enumeration.

THERAPEUTICS:

         One of the Company's major programs is the development of products
which inhibit a part of the immune system called the complement system.  The
complement cascade is a major initiator of the body's defense system and in
certain situations triggers harmful inflammatory responses resulting in the
death of viable tissue.  No treatment currently exists to inhibit the harmful
effects of complement mediated inflammation and other treatments for
inflammatory diseases do not directly address inflammation caused by complement
activation.

         The Company's lead complement product is soluble complement receptor B
or sCR1 (product name, TP10).  TCS recently completed a Phase I clinical trial
for TP10 in patients with acute lung injury at risk of developing ARDS.  A
Phase II trial is now being planned to evaluate TP10 in ARDS patients.  A
second Phase I trial is ongoing with the indication of reperfusion injury
following heart attacks.  A Phase II trial in reperfusion injury is being
planned for early 1996.  All development, marketing and manufacturing rights,
outside of Japan and Taiwan, to TP10 are owned by T Cell Sciences.

         In addition to TP10, T Cell Sciences is developing several other
complement inhibitors, including sLex CR1, which combines complement inhibition
with cell adhesion inhibition.  These product candidates, which are in
preclinical development, are proprietary to the Company.

         T Cell Sciences' second major program therapeutic is focused on using
the Company's proprietary T cell antigen receptor (TCAR) technology to develop
treatments for autoimmune diseases such as rheumatoid arthritis, multiple
sclerosis, Crohn's disease and T cell cancers.  The Company believes that use
of this technology will result in a new generation of immunosuppressive drugs
that selectively eliminate the function of specific T cell subgroups which are
thought to cause the disease while leaving the majority of T cells to perform
their normal function in the immune system.

         In January 1992, T Cell Sciences entered into a joint development and
distribution agreement with Astra, to develop jointly TCS's TCAR technology and
products for the treatment of autoimmune diseases and T cell cancers.  TCS and
Astra amended and restated this agreement in December 1993 to provide that TCS
will continue to develop TP12, a peptide, and Astra will assume development
responsibility for TM27, a humanized monoclonal antibody.  Astra has worldwide
marketing rights to the products developed from the joint program and T Cell
Sciences will receive a percentage of net sales of the products.

DIAGNOSTICS:

         T Cell Diagnostics is developing new human immuno-diagnostic products,
which would provide earlier warning of disease and more effective ways to
monitor and direct therapy.  TCD's lead product, TRAx(R) CD4, received marketing
clearance from the FDA in May 1995 and is now being launched through direct
sales efforts in the U.S. and distributors outside the U.S. TRAx CD4 is used for
enumerating the CD4+ T Cells in patients with infectious diseases, including
HIV.  TCD plans to submit TRAx CD8, a companion product to TRAx CD4, to the FDA
as a 510(k) submission before the end of 1995.  The potential market for TRAx
CD4 is approximately $75 million in the U.S. and Europe.  In clinical trials
conducted to support the Company's submission for clearance, TRAx CD4 provided
substantially equivalent results to those obtained from flow cytometry, the
method currently used to enumerate CD4 T cells. However, TRAx CD4 is a less
expensive alternative to flow cytometry, is more accessible to laboratories with
cell enumeration needs, has sample handling benefits and is more precise.  For
these reasons, T Cell Diagnostics believes TRAx CD4 has distinct marketing
advantages over flow cytometry.  Yamanouchi Pharmaceutical Co., Ltd. has rights
to market TRAx products in Japan and Taiwan.  T Cell Diagnostics is evaluating
different types of relationships with distributors and automated equipment
partners to maximize the penetration of different markets for the TRAx products.

         In addition to the TRAx product line, T Cell Diagnostics presently
sells approximately 40 products in the preclinical research market through
direct sales and distributors.

PATENTS:

         T Cell Sciences has an extensive patent portfolio supporting its
therapeutic and diagnostic efforts.  The Company is the owner or licensee of
over 200 patents and pending applications around the world, including 25 United
States patents.  Patent rights in the area of complement molecules include an
issued United States patent which claims the nucleic acid sequences of
recombinant soluble CR1 (TP10) and its fragments.  T Cell Sciences also owns
rights to a number of other patent applications relating to TP10, sCR1/SLex and
other complement inhibitor molecules.  Issued and pending T cell receptor
patent rights cover the DNA, protein, and antibodies relating to the alpha,
beta, gamma and delta chains of the T cell antigen receptor.  T Cell
Diagnostics is the owner of a number of patent rights relating to TRAx CD4 and
CD8, other applications of the TRAx product technologies, and new diagnostic
methods and products.

         The Company is a Delaware corporation founded in 1983. The Company's
principal offices and laboratories are located at 115 Fourth Avenue, Needham,
Massachusetts 02194 and its telephone number is 617-433-0771.


                                USE OF PROCEEDS

         The Company will not receive any proceeds from the sale of the Shares
by the Selling Stockholders.


                              RECENT DEVELOPMENTS

         Certain Shares covered by this Prospectus were acquired by the Selling
Stockholders from the Company in private placement transactions.  Certain
shares of Common Stock were purchased in a private placement transaction
pursuant to the Stock Purchase Agreements, dated as of October 27, 1995 (the
"October Stock Purchase Agreements") at a price per share of 20% below the
average of the high and low trading prices of the Common Stock on the Nasdaq
National Market on the five trading days preceding the Commitment Date (as
defined therein) of the October Stock Purchase Agreements, which price per share
as of the date of the October Stock Purchase Agreement was $2.825.   In the
October Stock Purchase Agreements, the Company agreed to bear all expenses in
connection with the registration and sale of Shares and up to $2,500 of the
outside counsel fees and expenses of the Selling Stockholders who acquired
Shares pursuant to the October Stock Purchase Agreements (the "October Selling
Stockholders").


                                       7

<PAGE>   10
         Certain Shares covered by this Prospectus were acquired by the 
Selling Shareholders from the Company in a separate private placement 
transaction pursuant to the Stock Purchase Agreements, dated as of November 
6, 1995 (the "November Stock Purchase Agreements") at a price per share of 
$2.50. In the November Stock Purchase Agreements, the Company agreed to bear 
all expenses in connection with the registration and sale of Shares (other than
underwriting discounts and selling commissions and the fees and expenses of 
counsel and other advisors to the Selling Stockholders).  The Company entered 
into a Placement Agency Agreement dated as of November 2, 1995 with Allen & 
Company Incorporated ("Allen & Company") pursuant to which the Company will pay
Allen & Company a commission of $0.10 per share of Common Stock purchased
by certain investors pursuant to the November Stock Purchase Agreements.  In
connection with the Placement Agency Agreement, the Company has also agreed to
pay up to $5,000 of Allen & Company's outside counsel fees and expenses.  See
"Plan of Distribution."

        Because certain Selling Stockholders have purchased shares of Common
Stock pursuant to the November Stock Purchase Agreements (the "November Selling
Stockholders") prior to the Closing Date (as defined therein) of the October
Stock Purchase Agreements at a lower price per share than the $2.825 price per
share reflected in the October Stock Purchase Agreements, the October Selling
Stockholders will receive additional shares of Common Stock at no additional
cost.  This issuance of additional shares of Common Stock to the October
Selling Stockholders is designed to result in the October Selling Shareholders
receiving the same price per share as the November Selling Stockholders.

        Certain Shares covered by this Prospectus will be acquired by the
Selling Stockholders from the Company through the exercise of warrants for
shares of Common Stock (the "Warrantholders"). These warrants were issued to
these Selling Stockholders in connection with a private placement of Class B
Preferred Stock in December 1985.   As consideration for the Company's
agreement to register shares of Common Stock issuable upon the exercise of
these warrants, the Warrantholders have expressed their intent to exercise
their warrants at the exercise price of $1.65 per share prior to the December
13, 1995 expiration  date of such warrants.

         Each Selling Stockholder represented in its respective Stock Purchase
Agreement or in its agreement with the Company that it was purchasing its
Shares from the Company or exercising its warrants for Shares of the Company
without any present intention of effecting a distribution of those Shares.  In
recognition of the fact, however, that investors may desire to sell their
Shares when they consider appropriate, and in accordance with its agreement
in the respective Stock Purchase Agreements and its agreement with the
Warrantholders, the Company has filed with the Commission a registration 
statement on Form S-3 (of which this Prospectus is a part, the "Registration 
Statement") with respect to the sale of the Shares by the Selling Stockholders 
from time to time on the Nasdaq National Market System or in negotiated 
transactions.   The Company will prepare and file such amendments and 
supplements to the Registration Statement as may be necessary to keep it
effective for a period not exceeding three years or such shorter period which
will terminate when all the Shares covered by such Registration Statement
have been sold pursuant to such Registration Statement or withdrawn.  The
Selling Shareholders (with the exception of the Selling Shareholders who have
acquired Shares through the exercise of warrants) agree to hold their Shares
for a period of thirty (30) days following the closing date of the transactions
contemplated by the respective Stock Purchase Agreements, which is the filing 
date of the Registration Statement of which this Prospectus is a part.

                              SELLING STOCKHOLDERS

         The Shares are to be offered by and for the respective accounts of the

         Except as set forth above, the Selling Stockholders have not held any
position or office with, been employed by, or otherwise had a material
relationship with the Company or any of its predecessors or affiliates.

                              PLAN OF DISTRIBUTION

         Shares of Common Stock covered hereby may be offered and sold from
time to time by the Selling Stockholders.  The Selling Stockholders will act
independently of the Company in making decisions with respect to the timing,
manner and size of each sale.  Such sales may be made in transactions in the
Nasdaq National Market System or otherwise at prices related to the then
current market price or in negotiated transactions.  The Shares may be sold by
one or more of the following methods:  (a) purchases by the broker-dealer as
principal and resale by such broker or dealer for its account pursuant to this
Prospectus; (b) ordinary brokerage transactions and transactions in which the
broker solicits purchasers; and (c) block trades in which the broker-dealer so
engaged will attempt to sell the Shares as agent but may position and resell a
portion of the block as principal to facilitate the transaction.  The Company
has been advised by the Selling Stockholders that they have not, as of the date
hereof, made any arrangements relating to the distribution of the Shares
covered by this Prospectus.  In effecting sales, broker-dealers engaged by the
Selling Stockholders may arrange for other broker-dealers to participate.
Broker-dealers will receive commissions or discounts from the Selling
Stockholders in amounts to be negotiated immediately prior to the sale.

         In offering the Shares of Common Stock covered hereby, the Selling
Stockholders and any broker-dealers who execute sales for the Selling
Stockholders may be deemed to be "underwriters" within the meaning of the
Securities Act in connection with such sales, and any profits realized by the
Selling Stockholders and the compensation of such broker-dealer may be deemed
to be underwriting discounts and commissions under the Securities Act.

         The Company has agreed to indemnify each Selling Stockholder against
any liabilities, under the Securities Act or otherwise, arising out of or based
upon any untrue or alleged untrue statement of a material fact in the
Registration Statement or this Prospectus or by any omission of a material fact
required to be stated therein except to the extent that such liabilities arise
out of or are based upon any untrue or alleged untrue statement or omission in
any information furnished in writing to the Company by the Selling Stockholder
expressly for use in the Registration Statement.


                                 LEGAL MATTERS

         The validity of the issuance of the Shares offered hereby will be
passed upon for the Company by its counsel, Goodwin, Procter & Hoar, Exchange
Place, 24th Floor, Boston, Massachusetts 02109.

ACT LIABILITIES

       Section 145 of the General Corporation Law of Delaware permits
indemnification of directors, officers and employees of a corporation under
certain conditions and subject to certain limitations.  Article FIFTH of the

policy which provides for payment of expenses of the registrant's directors and
officers in connection with threatened, pending or completed actions, suits or
proceedings against them in their capacities as directors and officers, in
accordance with the registrant's Amended and Restated By-Laws and the Delaware
General Corporation Law.  In addition, Article SIXTH of the Third Restated
Certificate of Incorporation of the registrant protects a director of the
registrant against any personal liability to the registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the
registrant or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any
transaction from which the director derived any improper benefit.

ITEM 17. UNDERTAKINGS.

A.       The undersigned registrant hereby undertakes:

         (1)     To file, during any period in which offers or sales are being
                 made, a post-effective amendment to this registration
                 statement.  To include any material information with respect
                 to the plan of distribution not previously disclosed in the
                 registration statement or any material change to such
                 information in the registration statement.

         (2)     That, for the purpose of determining any liability under the
                 Securities Act of 1933, each post- effective amendment shall
                 be deemed to be a new registration statement relating to the
                 securities offered therein, and the offering of such
                 securities at that time shall be deemed to be the initial bona
                 fide offering thereof.

         (3)     To remove from registration by means of a post-effective
                 amendment any of the securities being registered which remain
                 unsold at the termination of the offering.

B.       The undersigned registrant hereby undertakes that, for purposes of
         determining any liability under the Securities Act of 1933, each
         filing of the registrant's annual report pursuant to Section 13(a) or
         15(d) of the Securities Exchange Act of 1934 (and, where applicable,
         each filing of an employee benefit plan's annual report pursuant to
         Section 15(d) of the Securities Exchange Act of 1934) that is
         incorporated by reference in the registration statement shall be
         deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time
         shall be deemed to be the initial bona fide offering thereof.

C.       Insofar as indemnification for liabilities arising under the
         Securities Act of 1933 may be permitted to directors, officers and
         controlling persons of the registrant pursuant to the provisions
         described under Item 15 above, or otherwise, the registrant has been
         advised that in the opinion of the Securities and Exchange Commission
         such indemnification is against public policy as expressed in the Act
         and is, therefore, unenforceable. In the event that a claim for
         indemnification against such liabilities (other than the payment by
         the registrant of expenses incurred or paid by a director, officer or
         controlling person of the registrant in the successful defense of any
         action, suit or proceeding) is asserted by such director, officer or
         controlling person in connection with the securities being registered,
         the registrant will, unless in the opinion of its counsel the matter
         has been settled by controlling precedent, submit to a court of
         appropriate jurisdiction the question whether such indemnification by
         it is against public policy as expressed in the Act and will be
         governed by the final adjudication of such issue.

Ladies and Gentlemen:

         Re:     Registration Statement on Form S-3

         This opinion is delivered in our capacity as counsel to T Cell
Sciences, Inc. (the "Company") in connection with the sale by certain
stockholders of the Company (the "Selling Stockholders") of 2,761,816 shares
of the Company's Common Stock (the "Offered Shares").  The Offered Shares were
received by the Selling Stockholders pursuant to Stock Purchase Agreements,
dated as of either October 27, 1995 or November 6, 1995, by and between
the Selling Stockholders and the Company (the "Stock Purchase Agreements").
The Offered Shares are the subject of the Company's registration statement on
Form S-3 (the "Registration Statement") filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended.

         As counsel for the Company, we have examined the Registration
Statement, the Certificate of Incorporation and Bylaws of the Company each as
amended to date, certificates of action of the Company's Board of Directors,
the Stock Purchase Agreements, and such other records, certificates and
documents of the Company as we have deemed appropriate for the purposes of
 this
opinion.

         Based on and subject to the foregoing, we are of the opinion that when
the Offered Shares are sold by the Selling Stockholders as described in the
Registration Statement, the Offered Shares will be duly authorized, validly
issued, fully paid and non-assessable.

Registration Statement, to the reference therein to our firm, and to the
inclusion of this opinion as an exhibit to the Registration Statement.

                                        Very truly yours,



                                        GOODWIN, PROCTER & HOAR

                                                                    Exhibit 10.1

                                FORM OF OCTOBER
                            STOCK PURCHASE AGREEMENT


         THIS AGREEMENT is made as of the 27th day of October, 1995, between T
Cell Sciences, Inc. (the "Company"), a corporation organized under the laws of
the State of Delaware with its principal offices at 115 Fourth Avenue, Needham,
Massachusetts 02194, and the purchaser whose name and address is set forth on
the signature page hereof (the "Purchaser").

         IN CONSIDERATION of the mutual covenants contained in this Stock
Purchase Agreement, the Company and the Purchaser agree as follows:

         SECTION 1.  Authorization of Sale of the Shares.  Subject to the terms
and conditions of this Stock Purchase Agreement, the Company has authorized the
sale of up to 2,500,000 shares of common stock, par value $.001 per share of
the Company (the "Common Stock").  The Company reserves the right to sell more
than 2,500,000 shares of Common Stock prior to the date of the filing of the
Registration Statement (as defined in Section 3).  The shares of Common Stock
referred to in Section 2(a), the Supplemental Shares (as defined in Section 2)
and the Additional Shares (as defined in Section 7.2) are referred herein
collectively as the "Shares".

         SECTION 2.  Agreement to Sell and Purchase Shares.

                  (a)     At the Closing Date (as
 defined in Section 3), the
Company will sell to the Purchaser, and the Purchaser will buy from the
Company, upon the terms and conditions hereinafter set forth,______________
shares of Common Stock at the purchase price per Share equal to 20% below the
average of the daily high and low trading prices of the Common Stock on the
Nasdaq National Market on the five (5) trading days preceding the Commitment
Date (as defined in Section 3) (the "Stock Purchase Price").  As of the date
hereof such Stock Purchase Price is equal to $ _______ per share of Common
Stock, for an aggregate stock purchase price of $ _________________ (the
"Aggregate Stock Purchase Price").

                 (b)      The Company proposes to enter into a similar form of
Stock Purchase Agreement ("Other Stock Purchase Agreements") with certain other
investors (the "Other Purchasers").  The Purchaser and the Other Purchasers are
hereinafter sometimes collectively referred to as the "Purchasers," and this
Stock Purchase Agreement and the Other Stock Purchase Agreements are
hereinafter sometimes collectively referred to as the "Agreements."   The
Company may enter into Other Stock Purchase Agreements with Other Purchasers
prior to the Closing Date which may differ from this Stock Purchase Agreement
with respect to pricing or other terms.  If such material differences are
present in the Other Stock Purchase Agreements executed by Other Purchasers
prior to the Closing Date, the Company will notify the Purchaser by
distributing a supplemental Private Placement Memorandum disclosing such terms.

                 (c)      In the event the Other Stock Purchase Agreements
executed with Other Purchasers prior to the Closing Date include a price per
share of Common Stock which is less than $______ per share (the "Lower Share
Price"), upon the Closing Date, the Purchaser shall be granted additional
shares of Common Stock equal to the Aggregate Purchase Price divided by the
Lower

<PAGE>   2
Share Price, less the number of shares of Common Stock purchased by the
Purchaser (the "Supplemental Shares").

         SECTION 3.  Delivery of Shares on the Closing Date.

                 (a)      The commitment for the purchase and sale of the
shares of Common Stock (the "Commitment Date") shall occur on approximately
October 27, 1995 at a time and place specified by the Company.  On or prior to
the Commitment Date, the Purchaser shall have executed both the Stock Purchase
Agreement and the Registration Statement Questionnaire.  The Commitment Date
shall be prior to the time that the registration statement to be filed by the
Company pursuant to Section 7.1 (the "Registration Statement") is declared
effective.  The completion of the transaction contemplated hereby (the "Closing
Date") shall take place when the following have occurred: (i) the Company has
prepared and filed a Registration Statement on Form S-3 within ten (10)
business days of the Commitment Date relating to the Shares, (ii) the Purchaser
has placed the Aggregate Stock Purchase Price for the number of shares of
Common Stock, set forth in Section 2 above, pursuant to the Joint Escrow
Instructions in the form of Exhibit 3 attached hereto (the "Escrow Account");
and (iii) the Company shall have delivered to the Escrow Account one or more
certificates for the shares of Common Stock to be issued to the Purchaser on
the Closing Date.   On the Closing Date, there shall be released from the
Escrow Account to the Purchaser one or more stock certificates registered in
the name of the Purchaser representing the number of shares of Common Stock as
provided in Section 2 above, and all funds in the Escrow Account shall be
released to the Company pursuant to the Company's instructions attached hereto
as Exhibit 1.  Stock certificates evidencing the shares of Common Stock will be
delivered to the Escrow Account and released to the Purchaser on the Closing
Date with a legend in substantially the following form:

"THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933 AND MAY NOT BE OFFERED, SOLD, TRANSFERRED OR
HYPOTHECATED OR OTHERWISE ASSIGNED EXCEPT PURSUANT TO (I) A REGISTRATION
STATEMENT WITH RESPECT TO SUCH SECURITIES WHICH IS EFFECTIVE UNDER SUCH ACT OR
(II) RULE 144 OR 144A UNDER SUCH ACT OR  ANY  OTHER AVAILABLE EXEMPTION FROM
REGISTRATION UNDER SUCH ACT RELATING TO DISPOSITION OF SECURITIES."

 The name(s) in which the stock certificates are to be registered are set forth
in the Stock Certificate Questionnaire attached hereto as part of Appendix I.

                 (b)      The Company's obligation to complete the purchase and
sale of the shares of Common Stock and deliver such stock certificate(s) to the
Purchaser on the Closing Date shall be subject to the following conditions, any
one or more of which may be waived by the Company: (i) execution by the
Purchaser of a Stock Purchase Agreement (including the Stock Certificate
Questionnaire in Appendix I) and the Registration Statement Questionnaire, (ii)
delivery by the Purchaser of the Aggregate Stock Purchase Price for the number
of shares of Common Stock purchased as set forth in Section 2 above, to the
Escrow Account; (iii) release to the Company of such funds held in the Escrow
Account in the full amount of the Aggregate Stock Purchase Price for the number
of shares of Common Stock set forth in Section 2; and (iv) the accuracy of the
representations and warranties made by the Purchasers and the fulfillment of
those undertakings of the Purchasers to be fulfilled prior to the Closing Date.

<PAGE>   3
                 (c)      The Purchaser's obligation to accept delivery of such
stock certificates(s) and to pay for the shares of Common Stock evidenced
thereby on the Closing Date shall be subject to the following conditions, any
of which may be waived by the Purchaser: (i) the preparation and filing by the
Company of the Registration Statement on Form S-3 as required by Section 7.1
hereto, (ii) the accuracy in all material respects as of the Closing Date of
the representations and warranties made by the Company herein as if made on the
Closing Date; (iii) the fulfillment in all material respects of those
undertakings of the Company to be fulfilled prior to the Closing Date; (iv)
release from the Escrow Account to the Purchaser, against receipt by the
Company of the Aggregate Stock Purchase Price simultaneously released from the
Escrow Account, of the certificates for the number of shares of Common Stock as
provided in Section 2; and (v) receipt by the Purchasers of an opinion of
counsel to the Company, dated as of the Closing Date and addressed to the
Purchaser, in substantially the form attached hereto as Exhibit 2.  The
Purchaser's obligations hereunder are expressly not conditioned on the purchase
by any or all of the Other Purchasers of the shares of Common Stock that they
have agreed to purchase from the Company.

         SECTION 4.  Representations, Warranties and Covenants. The Company
hereby represents and warrants to, and covenants with, the Purchaser as
follows:

         4.1     Organization and Qualification.  The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to
conduct its business as currently conducted.

         4.2     Authorized Capital Stock.  As of October 18, 1995, the
authorized capital stock of the Company consisted of (a) 50,000,000 shares of
Common Stock, $.001 par value per share, of which 17,142,890 shares were
validly issued and outstanding, fully paid and non-assessable and with respect
to which warrants to purchase 211,816 shares were outstanding; (b) 1,163,102
shares of Class B Preferred Stock, $2.00 par value per share, of which no
shares were issued and outstanding; and (c) 3,000,000 shares of Class C
Preferred Stock, $.01 par value per share, of which no shares were issued and
outstanding.  As of October 18, 1995, 8,446 shares of Common Stock were held in
the treasury of the Company.  When issued and delivered to the Purchaser by the
Company against payment of the consideration set forth herein, the shares of
Common Stock, the Supplemental Shares, if any, and the Additional Shares (as
defined herein), if any, will be validly issued, fully paid and non-assessable.

         There are no preemptive rights of any stockholder of the Company, as
such, to acquire the Shares.  The Common Stock is authorized for trading on the
Nasdaq National Market and no suspension of trading in the Common Stock is in
effect.

         4.3     Due Execution, Delivery and Performance of the Agreements.
The Company's execution, delivery and performance of the Agreements (a) have
been duly authorized under Delaware law by all requisite corporate action by
the Company, (b) will not violate any law or the Certificate of Incorporation
or By-laws of the Company or any provision of any material indenture, mortgage,
agreement, contract or other material instrument to which the Company or any of
its subsidiaries is a party or by which the Company or any of its subsidiaries
or any of their properties or assets is bound as of the date hereof, and (c)
will not result in a breach of or constitute (upon notice or lapse of time or
both) a default under any such indenture, mortgage, agreement, contract or
other material instrument or the creation or imposition of any lien, security
interest, mortgage, pledge, charge or other encumbrance, of any material nature
whatsoever upon

<PAGE>   4
any properties or assets of the Company or any of its subsidiaries.  Upon their
execution and delivery, and assuming the valid execution thereof by the
respective Purchasers, the Agreements will constitute valid and binding
obligations of the Company, enforceable in accordance with their respective
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors' and
contracting parties' rights generally and except as enforceability may be
subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law) and except as
the indemnification and contribution agreements of the Company in Section 7.5
hereof may be legally unenforceable.

         4.4     Additional Information.  The Company represents and warrants
that the information contained in the following documents, which the Company
has furnished to the Purchaser, taken as a whole, does not contain any untrue
statement of material fact or omit to state any material fact necessary in
order to make the statements therein not misleading as of the respective final
dates of the documents.

                          10-K for the fiscal year ended December 31, 1994
                          (without exhibits);

                 (b)      the Company's Quarterly Reports on Form 10-Q for the
                          three-month periods ended March 31, 1995 and June 30,
                          1995;

                 (c)      Notice to Shareholders and Proxy Statement for its
                          Annual Meeting of Shareholders held May 18, 1995;

                 (d)      the Company's Current Reports on Form 8-K dated April
                          7, 1995 and May 18, 1995; and

                 (e)      the Private Placement Memorandum dated September 20, 
                          1995, as amended.

         4.5     No Material Change.  There has been no material adverse change
in the financial condition or business or results of operations of the Company
since June 30, 1995.

         4.6     Approvals.  No authorization, approval or consent of any
governmental body or the stockholders of the Company is required to be obtained
by the Company for the issuance and sale of the Shares as contemplated by this
Stock Purchase Agreement.

         4.7     Absence of Litigation.  Except as disclosed in the documents
referred to in Section 4.4, there is no action, suit, proceeding, inquiry or
investigation before or by any court, public board or body pending or, to the
knowledge of the Company or any of its subsidiaries, threatened against or
affecting the Company or any of its subsidiaries, wherein an unfavorable
decision, ruling or finding would have a material adverse effect on the
properties, business, condition (financial or other), results of operations or
prospects of the Company and its subsidiaries taken as a whole or the
transaction contemplated by this Stock Purchase Agreement or any of the
documents contemplated hereby or which would adversely affect the validity or
enforceability of, or the authority or ability of the Company to perform its
obligations under this Stock Purchase Agreement or any of such other documents.

         SECTION 5.  Representations, Warranties and Covenants of the Purchaser.

                 (a)      The Purchaser represents and warrants to, and
covenants with, the Company that:  (i) the Purchaser, taking into account the
personnel and resources it can practically bring to bear on the purchase of the
shares of Common Stock contemplated hereby, is knowledgeable, sophisticated and
experienced in making, and is qualified to make decisions with respect to
investments in securities presenting an investment decision like that involved

requested, received, reviewed and considered all information it deems relevant
in making an informed decision to purchase the shares of Common Stock; (ii) the
Purchaser is acquiring the Shares pursuant to this Stock Purchase Agreement in
the ordinary course of its business and for its own account for investment only
and with no present intention of distributing any of such Shares in violation
of the Securities Act of 1933, as amended (the "Securities Act") or in any
arrangement or understanding with any other persons regarding the distribution
of such Shares in violation of the Securities Act (this representation and
warranty not limiting the Purchaser's right to sell pursuant to the
Registration Statement or in a transaction not in violation of Section
5(a)(iii) hereof or, other than with respect to any claims arising out of a
breach of this representation and warranty, the Purchaser's right to
indemnification under Section 7.5); (iii) the Purchaser will not, directly or
indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit
any offers to buy, purchase or otherwise acquire or take a pledge of) any of
the Shares except in compliance with the Securities Act and the rules and
regulations promulgated thereunder; (iv) the Purchaser has completed or caused
to be completed the Registration Statement Questionnaire and the Stock
Certificate Questionnaire, both attached hereto as Appendix I, for use in
preparation of the Registration Statement and the answers thereto are true and
correct as of the date hereof and will be true and correct as of the effective
date of the Registration Statement; (v) the Purchaser has, in connection with
its decision to purchase the number of shares of Common Stock set forth in
Section 2 above, relied solely upon the representations and warranties of the
Company contained herein; (vi) the Purchaser is an "accredited investor" within
the meaning of Rule 501 of Regulation D promulgated under the Securities Act;
and (vii) that the Purchaser will hold the shares of Common Stock and the
Supplemental Shares for a period of thirty (30) days following the Closing
Date.

                 (b)      The Purchaser hereby covenants with the Company not
to make any sale of the Shares without effectively causing the prospectus
delivery requirement under the Securities Act to be satisfied or otherwise
complying with the Securities Act, and the Purchaser acknowledges and agrees
that the Shares are not transferable on the books of the Company unless the
certificate submitted to the transfer agent evidencing the Shares is
accompanied by (1) a separate certificate (i) in the form of Appendix II
hereto, (ii) executed by an officer of, or other authorized person designated
by, the Purchaser, and (iii) to the effect that (A) the Shares have been sold
in accordance with the Registration Statement and (B) the requirement of
delivering a current prospectus has been satisfied; or (2) an opinion of
counsel reasonably satisfactory to the Company stating that registration is not
required under the Securities Act.  The Purchaser acknowledges that there may
occasionally be times when the Company must suspend the use of the prospectus
forming a part of the Registration Statement until such time as an amendment to
the Registration Statement has been filed by the Company and declared effective
by the Commission, or until such time as the Company has filed an appropriate
report with the Commission pursuant to the Securities Exchange Act of 1934, as
amended; provided, however, that such suspension shall not be for a period of
more than two (2) trading days at any time or more than ten (10) trading days
in any one (1) year period.  The Purchaser hereby covenants that

<PAGE>   6
it will not sell any Shares pursuant to said prospectus during the period
commencing at the time at which the Company gives the Purchaser written notice
of the suspension of the use of said prospectus and ending the earlier of two
(2) trading days after such notice or occurrence or the date on which the
Company gives the Purchaser written notice that the Purchaser may thereafter
effect sales pursuant to said prospectus.

                 (c)      The Purchaser further represents and warrants to, and
covenants with, the Company that (i) the Purchaser has full right, power,
authority and capacity to enter into this Stock Purchase Agreement and to
consummate the transactions contemplated hereby and has taken all necessary
action to authorize the execution, delivery and performance of this Stock
Purchase Agreement, and (ii) upon the execution and delivery hereof, this Stock
Purchase Agreement shall constitute a valid and binding obligation of the
Purchaser enforceable in accordance with its terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or similar laws affecting creditors' and contracting parties' rights generally
and except as enforceability may be subject to general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) and except as the indemnification and contribution agreements
of the Purchaser in Section 7.5 hereof may be legally unenforceable.

         SECTION 6.  Survival of Representations, Warranties and Agreements.
Notwithstanding any investigation made by any party to this Stock Purchase
Agreement, all covenants, agreements, representations and warranties made by
the Company and the Purchaser herein and in the certificates for the shares of
Common Stock delivered pursuant hereto shall survive the execution of this
Stock Purchase Agreement, the delivery to the Purchaser of the shares of Common
Stock being purchased and the payment therefor.

         SECTION 7.  Registration of the Shares; Compliance with the Securities
Act.

         7.1     Registration Procedures and Expenses.  The Company shall:

                 (a)      prepare and file with the Commission within ten (10)

                          Statement on Form S-3 (the "Registration Statement")
                          to enable the sale of the Shares by the Purchaser
                          from time to time through the automated quotation
                          system of the Nasdaq National Market System or in
                          privately-negotiated transactions;

                 (b)      use its best efforts, subject to receipt of necessary
                          information from the Purchaser, to cause the
                          Registration Statement to become effective as soon as
                          possible after filing thereof;

                 (c)      promptly prepare and file with the Commission such
                          amendments and supplements to the Registration
                          Statement and the prospectus used in connection
                          therewith as may be necessary to keep the
                          Registration Statement effective for a period not
                          exceeding the third anniversary of the Closing Date
                          as is required for the intended method of
                          distribution, or such shorter period which will
                          terminate when all the Shares covered by such
                          Registration Statement have been sold pursuant to
                          such Registration Statement or withdrawn;

<PAGE>   7
                 (d)      promptly furnish to the Purchaser with respect to the
                          Shares registered under the Registration Statement
                          (and to each underwriter, if any, of such Shares)
                          such number of copies of the Registration Statement
                          and any amendment thereof and of prospectuses and
                          preliminary prospectuses in conformity with the
                          requirements of the Securities Act and such other
                          documents as the Purchaser may reasonably request, in
                          order to keep the Purchaser apprised of the progress
                          of the registration process and to facilitate the
                          public sale or other disposition of all or any of the
                          Shares by the Purchaser;

                 (e)      promptly file documents required of the Company for
                          normal blue sky clearance in states specified in
                          writing by the Purchaser and reasonably required by
                          the Purchaser in order to resell its Shares,
                          provided, however, that the Company shall not be
                          required to qualify to do business or consent to
                          service of process in any jurisdiction in which it is
                          not now so qualified or has not so consented;

                 (f)      promptly inform the Purchaser when any stop order by
                          the Commission has been issued with respect to the
                          Purchaser's Shares and use its best efforts to
                          promptly cause such stop order to be withdrawn; and

                 (g)      bear all expenses in connection with the procedures
                          in paragraphs (a) through (f) of this Section 7.1 and
                          the registration of the Shares pursuant to the
                          Registration Statement and pay up to $2,500 of
                          reasonable fees and expenses of outside counsel to
                          the Purchaser.

         A questionnaire related to the Registration Statement to be completed
by the Purchaser is attached hereto as part of Appendix I.

         7.2     Penalty for Delay of Registration Statement's Effective Date.
In the event the Registration Statement has not become effective by January 1,
1996, for each thirty (30) day period during which the shares of Common Stock
and the Supplemental Shares, if any, remain unregistered, the Company shall
issue to the Purchaser within three (3) trading days of the end of each such
thirty (30) day period, additional shares of Common Stock equal to 3% of the
total number of shares purchased by such Purchaser (the "Additional Shares") or
a cash payment equal to the average of the high and low sales prices of the
Common Stock on the Nasdaq National Market on the last trading day in such
30-day period multiplied by the number of Additional Shares which would
otherwise be issuable; provided, however, that in no event will the number of
Shares issued pursuant to the Agreements in the aggregate exceed 19.9% of the
total number of shares of Common Stock outstanding on the Closing Date (the
"Maximum Percentage"), and if such number of Shares to be issued pursuant to
the Agreements in the aggregate does exceed the Maximum Percentage, the Company
shall pay the Purchaser a cash payment equal to the aggregate market price of
the Additional Shares which would have resulted in exceeding the Maximum
Percentage.

         7.3     Exchange of Legended Certificates.  Following the effective
date of the Registration Statement, unless at such time a stop order is imposed
by the Commission or the effectiveness of the Registration Statement is for any
other reason suspended as permitted by Section 5(b) herein, all requirements
with respect to legends on the certificates evidencing the Shares will cease to

<PAGE>   8
apply on the sale thereof, and certificated Shares without legends will be
available to the Purchaser within three (3) trading days after the Company's
receipt of a request for such unlegended certificates and Purchaser's surrender
of the legend certificate to the Company's transfer agent.

         7.4     Transfer of Shares.  The Purchaser agrees that it will not
effect any disposition of the Shares or its right to purchase the Shares that
would constitute a sale within the meaning of the Securities Act except as
contemplated in the Registration Statement referred to in Section 7.1 or
pursuant to an exemption from registration under the Securities Act.  The
Purchaser agrees that it will promptly notify the Company of any changes in the
information set forth in the Registration Statement regarding the Purchaser or
its Plan of Distribution.

         7.5     Indemnification and Contribution.  For the purpose of this
Section 7.5:

                 (a)      the term "Selling Shareholder" shall include the
                          Purchaser, its officers, directors, trustees, any
                          affiliate of such Purchaser and each person, if any,
                          who controls the Selling Shareholder within the
                          meaning of the Securities Act;

                 (b)      the term "Registration Statement" shall include any
                          final prospectus, exhibit, supplement or amendment
                          included in or relating to the Registration Statement
                          referred to in Section 7.1;

                 (c)      the term "untrue statement" shall include any untrue
                          statement or alleged untrue statement, or any
                          omission or alleged omission to state in the
                          Registration Statement a material fact required to be
                          stated therein or necessary to make the statements
                          therein, in the light of the circumstances under
                          which they were made, not misleading.

         The Company agrees to indemnify and hold harmless each Selling
Shareholder from and against any losses, claims, damages or liabilities to
which such Selling Shareholder may become subject (under the Securities Act or
otherwise) insofar as such losses, claims, damages  or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or arise out of any failure by the Company to fulfill
any undertaking included in the Registration Statement and the Company will
reimburse such Selling Shareholder for any reasonable legal or other expenses
reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim, provided, however, that the Company shall not be
liable in any such case to the extent that such loss, claim, damage or
liability arises out of, or is based upon, any such untrue statement or
omission made in such Registration Statement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such
Selling Shareholder specifically for use in preparation of the Registration
Statement, or the failure of such Selling Shareholder to comply with the
covenants and agreements contained in Sections 5(b) or 7.4 hereof respecting
sale of the Shares or any statement or omission in any Prospectus that is
corrected in any subsequent Prospectus that was delivered to the Purchaser
prior to the pertinent sale or sales by the Purchaser.

<PAGE>   9
         The Purchaser agrees to indemnify and hold harmless the Company (and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act, each officer of the Company who signs the Registration
Statement and each director of the Company) from and against any losses,
claims, damages or liabilities to which the Company (or any such officer,
director or controlling person) may become subject (under the Securities Act or
otherwise), insofar as such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon, any failure
to comply with the covenants and agreements contained in Sections 5(b) or 7.4
hereof respecting sale of the Shares, or any untrue statement of a material
fact contained in the Registration Statement on the effective date thereof if
such untrue statement was made in reliance upon and in conformity with written
information furnished by or on behalf of the Purchaser specifically for use in
preparation of the Registration Statement, provided, however, that such
Purchaser shall not be liable in any such case to the extent that the Purchaser
has furnished in writing to the Company information expressly for use in such
Registration Statement or any amendment thereof or supplement thereto which
corrected or made not misleading, information previously furnished to the
Company prior to the filing of the Registration Statement, and if thereafter,
has notified the Company of such information immediately upon its occurrence or
the Purchaser's knowledge of its occurrence.  The Purchaser will reimburse the
Company (or such officer, director or controlling person), as the case may be,
for any legal or other expenses reasonably incurred in investigating, defending
or preparing to defend any such action, proceeding or claim.  In no event shall
the liability of the Purchaser hereunder be greater in amount than the dollar
amount of the proceeds received by such holder upon the sale of the Shares
giving rise to such indemnification obligation.

         Promptly after receipt by any indemnified person of a notice of a
claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 7.5, such
indemnified person shall notify the indemnifying person in writing of such
claim or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and such indemnifying person shall be entitled to
participate therein, and, to the extent it shall wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified person.
After notice from the indemnifying person to such indemnified person of its
election to assume the defense thereof, such indemnifying person shall not be
liable to such indemnified person for any legal expenses subsequently incurred
by such indemnified person in connection with the defense thereof, provided,
however, that if there exists or shall exist a conflict of interest that would
make it inappropriate, in the opinion of counsel to the indemnified person, for
the same counsel to represent both the indemnified person and such indemnifying
person or any affiliate or associate thereof, the indemnified person shall be
entitled to retain its own counsel at the expense of such indemnifying person;
provided, however, that no indemnifying person shall be responsible for the
fees and expenses of more than one separate counsel for all indemnified
parties.

         If the indemnification provided for in this Section 7.5 from the
indemnifying person is unavailable to an indemnified person hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
herein, then the indemnifying person, in lieu of indemnifying such indemnified
person, shall contribute to the amount paid or payable by such indemnified
person as a result of such losses, claims, damages, liabilities or expenses in
such proportion as is appropriate to reflect the relative fault of the
indemnifying person and indemnified persons in connection with the actions
which resulted in such losses, claims, damages, liabilities or expenses, as
well as any other relevant equitable considerations.  The relative fault of
such indemnifying

<PAGE>   10
person and indemnified persons shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact, has been made by, or relates to information
supplied by, such indemnifying person or indemnified persons, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such action.  The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in this Section 7.5,
any reasonable legal or other fees or expenses reasonably incurred by such
party in connection with any investigation or proceeding.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 7.5 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph.  Notwithstanding the provisions of this Section 7.5, no Purchaser
shall be required to contribute any amount in excess of the dollar amount of
the proceeds received by such Purchaser upon the sale of the Shares giving rise
to such contribution obligation.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

         7.6     Termination of Conditions and Obligations.  The conditions
precedent imposed by Section 5 or this Section 7 upon the transferability of
the Shares shall cease and terminate as to any particular number of the Shares
when such Shares shall have been effectively registered under the Securities
Act and sold or otherwise disposed of in accordance with the intended method of
disposition set forth in the Registration Statement covering such Shares or at
such time as an opinion of counsel satisfactory to the Company shall have been
rendered to the effect that such conditions are not reasonably necessary in
order to comply with the Securities Act.

         7.7     Information Available.  So long as the Registration Statement
is effective covering the resale of Shares owned by the Purchaser, the Company
will furnish to the Purchaser:

                 (a)      as soon as practicable after available (but in the
                          case of the Company's Annual Report to Shareholders,

                          principles by a national firm of certified public
                          accountants), (ii) if not included in substance in
                          the Annual Report to Shareholders, its Annual Report
                          on Form 10-K, (iii) its Quarterly Reports to

                          its Quarterly Reports to Shareholders, its quarterly
                          reports on Form 10-Q, and (v) a full copy of the
                          particular Registration Statement covering the Shares

                 (b)      upon the reasonable request of the Purchaser, all
                          exhibits excluded by the parenthetical to
                          subparagraph (a)(v) of this Section 7.7 and all other
                          information that is made available to shareholders;
                          and

                 (c)      upon the reasonable request of the Purchaser, an
                          adequate number of copies of the prospectuses to
                          supply to any other party requiring such
                          prospectuses;

<PAGE>   11
and the Company, upon the reasonable request of the Purchaser, will meet with
the Purchaser or a representative thereof at the Company's headquarters to
discuss all information relevant for disclosure in the Registration Statement
covering the Shares and will otherwise cooperate with any Purchaser conducting
an investigation for the purpose of reducing or eliminating such Purchaser's
exposure to liability under the Securities Act, including the reasonable
production of information at the Company's headquarters.

                                             ______________, 1995

PURCHASER


Purchaser:

        This opinion is furnished to you pursuant to Section ___ of that certain
Stock Purchase Agreement (the "Stock Purchase Agreements") dated as of
____________, 1995 by and between the purchasers (the "Purchaser") named therein
and T Cell Sciences, Inc. (the "Company"), relating to the offering and sale to
the Purchaser, subject to the terms and conditions set forth in the Stock
Purchase Agreement, of an aggregate of up to ______ shares of the Common Stock,
par value $.001 per share, of the Company (the "shares of Common Stock").

        We have acted as counsel for the Company in connection with the 
offering and sale of the shares of Common Stock. In such capacity, we have 
examined the Private Placement Memorandum dated September 20, 1995, as amended 
October 27, 1995 (the "Private Placement Memorandum"); signed copies of the 
Registration Statement of the Company on Form S-3 (Registration No. 33-______) 
and all exhibits thereto (the "Registration Statement"), as filed with the 
Securities and Exchange Commission (the "Commission") on ____________, 1995 
pursuant to the Securities Act of 1933, as amended (the "Securities Act"); the 
Prospectus dated ____________, 1995 (the "Prospectus"); and signed copies of 
the Stock Purchase Agreement.

        We also have examined originals or copies of the following with respect 
to the Company:

        (a)     the Company's Certificate of Incorporation (the "Certificate of
        Incorporation"), certified by the Secretary of State of the State of
        Delaware as of a recent date;

        (b)     the Company's By-Laws, as amended, certified by the Secretary of
        the Company as in effect as of the date hereof;

        (c)     a certificate of the Secretary of State of the State of
        Delaware, dated as of a recent date, certifying as to the Company's
        legal existence and good standing;

        (d)     such records of the Company's corporate proceedings as we have
        deemed relevant;

        (e)     a certificate of certain officers of the Company concerning the
        outstanding capital stock of the Company and the payment therefor and
        other matters; and


<PAGE>   19
        (f)     a certificate of the Company's transfer agent concerning the 
        outstanding capital stock of the Company.

        We have also examined and relied upon such other contracts, documents, 
certificates and records as we deemed necessary for the purpose of this 
opinion, including those delivered today at the closing of the sale of the 
shares of Common Stock. In such examination, we have assumed the genuineness 
of all signatures, the capacity, power and authority of all parties other than 
the Company to execute and deliver all applicable documents, the authenticity 
of all documents submitted to us as originals, the conformity to originals of 
all documents submitted to us as certified or attested copies or photocopies 
and the authenticity of the originals of such latter documents.

        We express no opinion herein as to the accuracy, completeness, 
fairness or compliance as to form of the statements contained in the Private 
Placement Memorandum or the Stock Purchase Agreement. We are not passing in any 
way on any financial statements or data, including the schedules or the notes 
thereto, or any related statistics or computations referred to in the Private 
Placement Memorandum, the Registration Statement or the Prospectus, and we 
have not reviewed the financial records or books of account of the Company.

        Whenever our opinion is indicated to be based on "the best of our 
knowledge" or contains a similar qualification, it should be understood that 
during the course of our representation of the Company we have not undertaken 
any independent investigation to determine the existence or absence of facts. 
The words "the best of our knowledge" and similar language used in certain of 
the opinions expressed below are limited to the knowledge of the lawyers 
within our firm who have had primary responsibility for the legal services 
performed for the Company.

        We are members of the Bar of the Commonwealth of Massachusetts, and we 
express no opinion herein with respect to any law other than the laws of the 
Commonwealth of Massachusetts and the United States of America and the 
corporate laws of the State of Delaware as in effect on the date hereof.

        Based upon and subject to the foregoing, we are of the opinion that:

        1.      The Company is a corporation duly organized, validly existing 
and in corporate good standing under the laws of the State of Delaware, with 
full corporate power and authority to conduct its business as currently 
conducted.

        2.      As of October 18, 1995, the authorized capital stock of the 
Company consisted of (a) 50,000,000 shares of Common Stock, $.001 par value per 
share, of which 17,142,890 shares were validly issued and outstanding, fully 
paid and non-assessable and with respect to which warrants to purchase 211,816 
shares were outstanding; (b) 1,163,102 shares of Class B Preferred Stock, 
$2.00 par value per share, of which no shares were issued and outstanding; and 
(c) 3,000,000 shares of Class C Preferred Stock, $.01 par value per share, of 
which no shares were issued and outstanding. As of October 18, 1995, 8,446 
shares of Common Stock were held in the treasury of the Company. The authorized 
shares of the Company's Common 



<PAGE>   20
Stock have been duly authorized; the outstanding shares of its Common Stock 
have been duly authorized and validly issued and are fully paid and 
nonassessable; the shares of Common Stock to be sold by the Company pursuant to 
the Stock Purchase Agreement have been duly authorized and will be validly 
issued, fully paid and nonassessable when issued and paid for as contemplated 
by the Stock Purchase Agreement; and no preemptive rights arising under the 
Company's Certificate of Incorporation, and to the best of our knowledge, no 
preemptive rights, registration rights, rights of first refusal or other 
similar rights of stockholders arising under any agreement or instrument to 
which the Company is a party or by which the Company may be bound, exist with 
respect to any of the shares or the issue and sale thereof, other than those 
that have been complied with or expressly waived prior to the date hereof by 
the holders thereof.

        3. All corporate action on the part of the Company, its directors and 
shareholders necessary for the authorization, execution, delivery and 
performance by the Company of the Stock Purchase Agreements, the consummation 
by the Company of the transactions contemplated therein and the authorization 
and issuance of the shares of Common Stock has been taken. The Stock Purchase 
Agreement and the other documents to be delivered by the Company thereunder 
constitute the valid and binding obligations of the Company, enforceable 
against it in accordance with their terms, except (i) as such enforceability 
may be limited by any principles of public policy with respect to enforcement 
of any indemnification provisions contained therein or by bankruptcy, 
insolvency, reorganization, moratorium or similar laws relating to or affecting 
generally the enforcement of creditors' rights, and (ii) to the extent that 
availability of the remedy of specific performance or injunctive relief is 
subject to the discretion of the court before which any proceeding therefor may 
be brought.

        4. The execution, delivery and performance by the Company of the Stock 
Purchase Agreements and the issuance of the shares of Common Stock will not (i) 
result in any violation of or be in conflict with or constitute a default (or 
an event which, with the lapse of time, or the giving of notice, or both will 
constitute a default) under any term of the Company's Certificate of 
Incorporation or By-Laws, or (ii) to the best of our knowledge, result in any 
violation of or be in conflict with or constitute a default (or an event which, 
with the lapse of time or the giving of notice, or both, will constitute a 
default) under any term of any existing material mortgage, indenture, contract, 
agreement, instrument, law, regulation, judgment, decree or order applicable to 
the Company or to which the Company is subject, or (iii) to the best of our 
knowledge, result in the creation of any mortgage, pledge, lien, encumbrance or 
charge upon any of the properties or assets of the Company.

        5. Assuming the accuracy of the representations and warranties made by 
the Purchaser in the Stock Purchase Agreement, the Private Placement 
Memorandum, the exhibits and appendices thereto (except for the financial 
statements and schedules and statistical data, including the schedules and 
notes to the financial statements included therein, as to which no statement is 
made) comply as to form in all material respects with the requirements of 
Regulation D promulgated by the Commission pursuant to the Securities Act, and 
no registration under the Securities Act is required in connection with the 
issuance and sale of the shares of Common Stock in accordance with the 
exemption from registration provided under Regulation D.


<PAGE>   21
        6.      No authorization, approval or consent of any governmental body, 
regulatory agency, self-regulatory body or the stockholders of the Company is 
required to be obtained by the Company for the issuance and sale of the Shares 
as contemplated by the Stock Purchase Agreement; and

        7.      Except as disclosed in the documents referred to in Section 4.4 
of the Stock Purchase Agreement, there is no action, suit, proceeding, inquiry 
or investigation before or by any court, public board or body pending or, to 
the best of our knowledge, threatened against or affecting the Company or any 
of its subsidiaries, wherein an unfavorable decision, ruling or finding would 
have a material adverse effect on the properties, business, condition 
(financial or other), results of operations or prospects of the Company and its 
subsidiaries taken as a whole or the transactions contemplated by the Stock 
Purchase Agreement or any of the documents contemplated thereby or which would 
adversely affect the validity or enforceability of, or the authority or ability 
of the Company to perform its obligations under, the Stock Purchase Agreement 
or any of such other documents.

        Prior to ____________, 1995, we participated in conferences with 
officers and other representatives of the Company at which the contents of the 
Private Placement Memorandum, and related matters were discussed. There can be 
no assurance that all possible material facts as to the Company were disclosed 
in such conferences. We have not undertaken to verify independently the 
statements made in the documents and conferences referred to above and 
therefore are not passing upon or assuming any responsibility for the accuracy, 
completeness or fairness of the statements contained in the Private Placement 
Memorandum but we hereby confirm to you, on the basis of the foregoing, that no 
facts have come to our attention which lead us to believe that the Private 
Placement Memorandum and the exhibits thereto (except for the financial 
statements and schedules and statistical data, including the schedules and 
notes to the financial statements included therein, as to which no statement is 
made), as of its date and as of the date hereof, contained any untrue statement 
of a material fact or omitted to state a material fact required to be stated 
therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading.

This opinion is rendered to you and is solely for your benefit in your capacity 
as placement agent for the shares of Common Stock, and may not be relied upon 
by you for any other purpose, or furnished to, quoted to or relied upon by any 
other person for any purpose without our prior written consent.

                                        Very truly yours,

                                        GOODWIN, PROCTER & HOAR

                                FORM OF NOVEMBER

         SECTION 4.  Representations, Warranties and Covenants. The Company
hereby represents and warrants to, and covenants with, the Purchaser as
follows:

         4.1     Organization and Qualification.  The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to
conduct its business as currently conducted.

         4.2     Authorized Capital Stock.  As of October 18, 1995, the

Company against payment of the consideration set forth herein, the shares of
Common Stock and the Additional Shares (as defined herein), if any, will be

Nasdaq National Market and no suspension of trading in the Common Stock is in
effect.

         4.3     Due Execution, Delivery and Performance of the Agreements.
The Company's execution, delivery and performance of the Agreements (a) have
been duly authorized under Delaware law by all requisite corporate action by
the Company, (b) will not violate any law or the Certificate of Incorporation

its subsidiaries is a party or by which the Company or any of its subsidiaries
or any of their properties or assets is bound as of the date hereof, and (c)
will not result in a breach of or constitute (upon notice or lapse of time or
both) a default under any such indenture, mortgage, agreement, contract or
other material instrument or the creation or imposition of any lien, security
interest, mortgage, pledge, charge or other encumbrance, of any material nature
whatsoever upon any properties or assets of the Company or any of its
subsidiaries.  Upon their execution and delivery, and assuming the valid
execution thereof by the respective Purchasers, the Agreements will constitute
valid and binding obligations of the Company, enforceable in accordance with
their respective terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' and contracting parties' rights generally and except as
enforceability may be subject to general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law)
and except as the indemnification and contribution agreements of the Company in
Section 7.5 hereof may be legally unenforceable.

         4.4     Additional Information.  The Company represents and warrants
that the information contained in the following documents, which the Company
has furnished to the Purchaser, taken as a whole, does not contain any untrue

SECTION 5.  Representations, Warranties and Covenants of the Purchaser.

                 (a)      The Purchaser represents and warrants to, and
covenants with, the Company that:  (i) the Purchaser, taking into account the
personnel and resources it can practically bring to bear on the purchase of the
shares of Common Stock contemplated hereby, is knowledgeable, sophisticated and

of the Securities Act of 1933, as amended (the "Securities Act") or in any
arrangement or understanding with any other persons regarding the distribution
of such Shares in violation of the Securities Act (this representation and
warranty not limiting the Purchaser's right to sell pursuant to the
Registration

thereunder; (iv) the Purchaser has completed or caused to be completed the
Registration Statement Questionnaire and the Stock Certificate Questionnaire,
both attached hereto as Appendix I, for use in preparation of the Registration
Statement and the answers thereto are true and correct as of the date hereof
and will be true and correct as of the effective date of the Registration

delivery requirement under the Securities Act to be satisfied or otherwise
complying with the Securities Act, and the Purchaser acknowledges and agrees

Purchaser enforceable in accordance with its terms, except as enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or similar laws affecting creditors' and contracting parties' rights generally
and except as enforceability may be subject to general principles of equity
(regardless of whether such

<PAGE>   6

hereof may be legally unenforceable.

Agreement, all covenants, agreements, representations and warranties made by
the Company and the Purchaser herein and in the certificates for the shares of

                          as is required for the intended method of
                          distribution, or such shorter period which will
                          terminate when all the Shares covered by such
                          Registration Statement have been sold pursuant to
                          such Registration Statement or withdrawn;

                 (d)      promptly furnish to the Purchaser with respect to the

                          writing by the Purchaser and reasonably required by
                          the Purchaser in order to resell its Shares,
                          provided, however, that the Company shall not be
                          required to qualify to do business or consent to
                          service of process in any jurisdiction in which it is

<PAGE>   7
                 (f)      promptly inform the Purchaser when any stop order by
                          the Commission has been issued with respect to the

                          Registration Statement, other than fees and expenses,
                          if any, of counsel or other advisors to the
                          Purchaser.

         A questionnaire related to the Registration Statement to be completed
by the Purchaser is attached hereto as part of Appendix I.

         7.2     Penalty for Delay of Registration Statement's Effective Date.
In the event the Registration Statement has not become effective by January 1,
1996, for each thirty (30) day period during which the Shares remain
unregistered, the Company shall issue to the Purchaser within three (3) trading
days of the end of each such 30-day period, additional shares of Common Stock
equal to 3% of the total number of shares purchased by such Purchaser (the
"Additional Shares") or a cash payment equal to the average high and low sales
prices of the Common Stock on the Nasdaq National Market on the last trading
day in such 30-day period multiplied by the number of Additional Shares
issuable; provided, however, that in no event will the number of Shares issued
pursuant to the Agreements in the aggregate exceed 19.9% of the total number of
shares of Common Stock outstanding on the Closing Date (the "Maximum
Percentage"), and if such number of Shares to be issued pursuant to the
Agreements in the aggregate does exceed the Maximum Percentage, the Company
shall pay the Purchaser a cash payment equal to the average high and low sales
prices of the Common Stock on the Nasdaq National Market on the last trading
day in such 30-day period multiplied by the number of Additional Shares which
would have resulted in exceeding the Maximum Percentage.

         7.3     Exchange of Legended Certificates.  Following the effective
date of the Registration Statement, unless at such time a stop order is imposed
by the Commission or the effectiveness of the Registration Statement is for any
other reason suspended as permitted by Section 5(b) herein, all requirements
with respect to legends on the certificates evidencing the Shares will cease to
apply on the sale thereof, and certificated Shares without legends will be
available to the Purchaser within three (3) trading days after the Company's
receipt of a request for such unlegended certificates and Purchaser's surrender
of the legend certificate to the Company's transfer agent.

         7.4     Transfer of Shares.  The Purchaser agrees that it will not
effect any disposition of the Shares or its right to purchase the Shares that
would constitute a sale within the meaning of the Securities Act except as
contemplated in the Registration Statement referred to in Section 7.1 or
pursuant to an exemption from registration under the Securities Act.  The
Purchaser agrees that it will promptly notify the Company of any changes in the
information set forth in the Registration Statement regarding the Purchaser or
its Plan of Distribution.

         7.5     Indemnification and Contribution.  For the purpose of this
Section 7.5:

                 (a)      the term "Selling Shareholder" shall include the
                          Purchaser, its officers, directors, trustees, any
                          affiliate of such Purchaser and each person, if any,

<PAGE>   8
                          who controls the Selling Shareholder within the 
                          meaning of the Securities Act;

                 (b)      the term "Registration Statement" shall include any
                          final prospectus, exhibit, supplement or amendment
                          included in or relating to the Registration Statement
                          referred to in Section 7.1;

                 (c)      the term "untrue statement" shall include any untrue
                          statement or alleged untrue statement, or any
                          omission or alleged omission to state in the
                          Registration Statement a material fact required to be
                          stated therein or necessary to make the statements
                          therein, in the light of the circumstances under
                          which they were made, not misleading.

         The Company agrees to indemnify and hold harmless each Selling
Shareholder from and against any losses, claims, damages or liabilities to
which such Selling Shareholder may become subject (under the Securities Act or
otherwise) insofar as such losses, claims, damages  or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or arise out of any failure by the Company to fulfill
any undertaking included in the Registration Statement and the Company will
reimburse such Selling Shareholder for any reasonable legal or other expenses
reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim, provided, however, that the Company shall not be
liable in any such case to the extent that such loss, claim, damage or
liability arises out of, or is based upon, any such untrue statement or
omission made in such Registration Statement in reliance upon and in conformity
with written information furnished to the Company by or on behalf of such
Selling Shareholder specifically for use in preparation of the Registration
Statement, or the failure of such Selling Shareholder to comply with the
covenants and agreements contained in Sections 5(b) or 7.4 hereof respecting
sale of the Shares or any statement or omission in any Prospectus that is
corrected in any subsequent Prospectus that was delivered to the Purchaser
prior to the pertinent sale or sales by the Purchaser.

         The Purchaser agrees to indemnify and hold harmless the Company (and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act, each officer of the Company who signs the Registration
Statement and each director of the Company) from and against any losses,
claims, damages or liabilities to which the Company (or any such officer,
director or controlling person) may become subject (under the Securities Act or
otherwise), insofar as such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon, any failure
to comply with the covenants and agreements contained in Sections 5(b) or 7.4
hereof respecting sale of the Shares, or any untrue statement of a material
fact contained in the Registration Statement on the effective date thereof if
such untrue statement was made in reliance upon and in conformity with written
information furnished by or on behalf of the Purchaser specifically for use in
preparation of the Registration Statement, provided, however, that such
Purchaser shall not be liable in any such case to the extent that the Purchaser
has furnished in writing to the Company information expressly for use in such
Registration Statement or any amendment thereof or supplement thereto which
corrected or made not misleading, information previously furnished to the
Company prior to the filing of the Registration Statement, and if thereafter,
has notified the Company of such information

<PAGE>   9
immediately upon its occurrence or the Purchaser's knowledge of its occurrence.
The Purchaser will reimburse the Company (or such officer, director or
controlling person), as the case may be, for any legal or other expenses
reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim.  In no event shall the liability of the Purchaser
hereunder be greater in amount than the dollar amount of the proceeds received
by such holder upon the sale of the Shares giving rise to such indemnification
obligation.

         Promptly after receipt by any indemnified person of a notice of a
claim or the beginning of any action in respect of which indemnity is to be
sought against an indemnifying person pursuant to this Section 7.5, such
indemnified person shall notify the indemnifying person in writing of such
claim or of the commencement of such action, and, subject to the provisions
hereinafter stated, in case any such action shall be brought against an
indemnified person and such indemnifying person shall be entitled to
participate therein, and, to the extent it shall wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified person.
After notice from the indemnifying person to such indemnified person of its
election to assume the defense thereof, such indemnifying person shall not be
liable to such indemnified person for any legal expenses subsequently incurred
by such indemnified person in connection with the defense thereof, provided,
however, that if there exists or shall exist a conflict of interest that would
make it inappropriate, in the opinion of counsel to the indemnified person, for
the same counsel to represent both the indemnified person and such indemnifying
person or any affiliate or associate thereof, the indemnified person shall be
entitled to retain its own counsel at the expense of such indemnifying person;
provided, however, that no indemnifying person shall be responsible for the
fees and expenses of more than one separate counsel for all indemnified
parties.

         If the indemnification provided for in this Section 7.5 from the
indemnifying person is unavailable to an indemnified person hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
herein, then the indemnifying person, in lieu of indemnifying such indemnified
person, shall contribute to the amount paid or payable by such indemnified
person as a result of such losses, claims, damages, liabilities or expenses in
such proportion as is appropriate to reflect the relative fault of the
indemnifying person and indemnified persons in connection with the actions
which resulted in such losses, claims, damages, liabilities or expenses, as
well as any other relevant equitable considerations.  The relative fault of
such indemnifying person and indemnified persons shall be determined by
reference to, among other things, whether any action in question, including any
untrue or alleged untrue statement of a material fact, has been made by, or
relates to information supplied by, such indemnifying person or indemnified
persons, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such action.  The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set
forth in this Section 7.5, any reasonable legal or other fees or expenses
reasonably incurred by such party in connection with any investigation or
proceeding.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 7.5 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph.  Notwithstanding the provisions of this Section 7.5, no Purchaser
shall be required to contribute any amount in excess of the dollar amount of
the proceeds received by such Purchaser upon the sale of the Shares giving rise
to such contribution obligation.  No person guilty of

<PAGE>   10
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

         7.6     Termination of Conditions and Obligations.  The conditions
precedent imposed by Section 5 or this Section 7 upon the transferability of
the Shares shall cease and terminate as to any particular number of the Shares
when such Shares shall have been effectively registered under the Securities
Act and sold or otherwise disposed of in accordance with the intended method of
disposition set forth in the Registration Statement covering such Shares or at
such time as an opinion of counsel satisfactory to the Company shall have been
rendered to the effect that such conditions are not reasonably necessary in
order to comply with the Securities Act.

         7.7     Information Available.  So long as the Registration Statement
is effective covering the resale of Shares owned by the Purchaser, the Company
will furnish to the Purchaser:

                          principles by a national firm of certified public
                          accountants), (ii) if not included in substance in
                          the Annual Report to Shareholders, its Annual Report

                          particular Registration Statement covering the Shares

                 (b)      upon the reasonable request of the Purchaser, all
                          exhibits excluded by the parenthetical to
                          subparagraph (a)(v) of this Section 7.7 and all other
                          information that is made available to shareholders;
                          and

                          supply to any other party requiring such
                          prospectuses;

and the Company, upon the reasonable request of the Purchaser, will meet with
the Purchaser or a representative thereof at the Company's headquarters to
discuss all information relevant for disclosure in the Registration Statement
covering the Shares and will otherwise cooperate with any Purchaser conducting
an investigation for the purpose of reducing or eliminating such Purchaser's
exposure to liability under the Securities Act, including the reasonable
production of information at the Company's headquarters.

PURCHASER


Purchaser:

        This opinion is furnished to you pursuant to Section ___ of that certain
Stock Purchase Agreement (the "Stock Purchase Agreements") dated as of
____________, 1995 by and between the purchasers (the "Purchaser") named therein
and T Cell Sciences, Inc. (the "Company"), relating to the offering and sale to
the Purchaser, subject to the terms and conditions set forth in the Stock
Purchase Agreement, of an aggregate of up to ______ shares of the Common Stock,
par value $.001 per share, of the Company (the "shares of Common Stock").

        We have acted as counsel for the Company in connection with the 
offering and sale of the shares of Common Stock. In such capacity, we have 
examined the Private Placement Memorandum dated September 20, 1995, as amended 
October 27, 1995 (the "Private Placement Memorandum"); signed copies of the 
Registration Statement of the Company on Form S-3 (Registration No. 33-______) 
and all exhibits thereto (the "Registration Statement"), as filed with the 
Securities and Exchange Commission (the "Commission") on ____________, 1995 
pursuant to the Securities Act of 1933, as amended (the "Securities Act"); the 
Prospectus dated ____________, 1995 (the "Prospectus"); and signed copies of 
the Stock Purchase Agreement.

        We also have examined originals or copies of the following with respect 
to the Company:

        (a)     the Company's Certificate of Incorporation (the "Certificate of
        Incorporation"), certified by the Secretary of State of the State of
        Delaware as of a recent date;

        (b)     the Company's By-Laws, as amended, certified by the Secretary of
        the Company as in effect as of the date hereof;

        (c)     a certificate of the Secretary of State of the State of
        Delaware, dated as of a recent date, certifying as to the Company's
        legal existence and good standing;

        (d)     such records of the Company's corporate proceedings as we have
        deemed relevant;

        (e)     a certificate of certain officers of the Company concerning the
        outstanding capital stock of the Company and the payment therefor and
        other matters; and


<PAGE>   18
        (f)     a certificate of the Company's transfer agent concerning the 
        outstanding capital stock of the Company.

        We have also examined and relied upon such other contracts, documents, 
certificates and records as we deemed necessary for the purpose of this 
opinion, including those delivered today at the closing of the sale of the 
shares of Common Stock. In such examination, we have assumed the genuineness 
of all signatures, the capacity, power and authority of all parties other than 
the Company to execute and deliver all applicable documents, the authenticity 
of all documents submitted to us as originals, the conformity to originals of 
all documents submitted to us as certified or attested copies or photocopies 
and the authenticity of the originals of such latter documents.

        We express no opinion herein as to the accuracy, completeness, 
fairness or compliance as to form of the statements contained in the Private 
Placement Memorandum or the Stock Purchase Agreement. We are not passing in any 
way on any financial statements or data, including the schedules or the notes 
thereto, or any related statistics or computations referred to in the Private 
Placement Memorandum, the Registration Statement or the Prospectus, and we 
have not reviewed the financial records or books of account of the Company.

        Whenever our opinion is indicated to be based on "the best of our 
knowledge" or contains a similar qualification, it should be understood that 
during the course of our representation of the Company we have not undertaken 
any independent investigation to determine the existence or absence of facts. 
The words "the best of our knowledge" and similar language used in certain of 
the opinions expressed below are limited to the knowledge of the lawyers 
within our firm who have had primary responsibility for the legal services 
performed for the Company.

        We are members of the Bar of the Commonwealth of Massachusetts, and we 
express no opinion herein with respect to any law other than the laws of the 
Commonwealth of Massachusetts and the United States of America and the 
corporate laws of the State of Delaware as in effect on the date hereof.

        Based upon and subject to the foregoing, we are of the opinion that:

        1.      The Company is a corporation duly organized, validly existing 
and in corporate good standing under the laws of the State of Delaware, with 
full corporate power and authority to conduct its business as currently 
conducted.

        2.      As of October 18, 1995, the authorized capital stock of the 
Company consisted of (a) 50,000,000 shares of Common Stock, $.001 par value per 
share, of which 17,142,890 shares were validly issued and outstanding, fully 
paid and non-assessable and with respect to which warrants to purchase 211,816 
shares were outstanding; (b) 1,163,102 shares of Class B Preferred Stock, 
$2.00 par value per share, of which no shares were issued and outstanding; and 
(c) 3,000,000 shares of Class C Preferred Stock, $.01 par value per share, of 
which no shares were issued and outstanding. As of October 18, 1995, 8,446 
shares of Common Stock were held in the treasury of the Company. The authorized 
shares of the Company's Common 



<PAGE>   19
Stock have been duly authorized; the outstanding shares of its Common Stock 
have been duly authorized and validly issued and are fully paid and 
nonassessable; the shares of Common Stock to be sold by the Company pursuant to 
the Stock Purchase Agreement have been duly authorized and will be validly 
issued, fully paid and nonassessable when issued and paid for as contemplated 
by the Stock Purchase Agreement; and no preemptive rights arising under the 
Company's Certificate of Incorporation, and to the best of our knowledge, no 
preemptive rights, registration rights, rights of first refusal or other 
similar rights of stockholders arising under any agreement or instrument to 
which the Company is a party or by which the Company may be bound, exist with 
respect to any of the shares or the issue and sale thereof, other than those 
that have been complied with or expressly waived prior to the date hereof by 
the holders thereof.

        3. All corporate action on the part of the Company, its directors and 
shareholders necessary for the authorization, execution, delivery and 
performance by the Company of the Stock Purchase Agreements, the consummation 
by the Company of the transactions contemplated therein and the authorization 
and issuance of the shares of Common Stock has been taken. The Stock Purchase 
Agreement and the other documents to be delivered by the Company thereunder 
constitute the valid and binding obligations of the Company, enforceable 
against it in accordance with their terms, except (i) as such enforceability 
may be limited by any principles of public policy with respect to enforcement 
of any indemnification provisions contained therein or by bankruptcy, 
insolvency, reorganization, moratorium or similar laws relating to or affecting 
generally the enforcement of creditors' rights, and (ii) to the extent that 
availability of the remedy of specific performance or injunctive relief is 
subject to the discretion of the court before which any proceeding therefor may 
be brought.

        4. The execution, delivery and performance by the Company of the Stock 
Purchase Agreements and the issuance of the shares of Common Stock will not (i) 
result in any violation of or be in conflict with or constitute a default (or 
an event which, with the lapse of time, or the giving of notice, or both will 
constitute a default) under any term of the Company's Certificate of 
Incorporation or By-Laws, or (ii) to the best of our knowledge, result in any 
violation of or be in conflict with or constitute a default (or an event which, 
with the lapse of time or the giving of notice, or both, will constitute a 
default) under any term of any existing material mortgage, indenture, contract, 
agreement, instrument, law, regulation, judgment, decree or order applicable to 
the Company or to which the Company is subject, or (iii) to the best of our 
knowledge, result in the creation of any mortgage, pledge, lien, encumbrance or 
charge upon any of the properties or assets of the Company.

        5. Assuming the accuracy of the representations and warranties made by 
the Purchaser in the Stock Purchase Agreement, the Private Placement 
Memorandum, the exhibits and appendices thereto (except for the financial 
statements and schedules and statistical data, including the schedules and 
notes to the financial statements included therein, as to which no statement is 
made) comply as to form in all material respects with the requirements of 
Regulation D promulgated by the Commission pursuant to the Securities Act, and 
no registration under the Securities Act is required in connection with the 
issuance and sale of the shares of Common Stock in accordance with the 
exemption from registration provided under Regulation D.


<PAGE>   20
        6.      No authorization, approval or consent of any governmental body, 
regulatory agency, self-regulatory body or the stockholders of the Company is 
required to be obtained by the Company for the issuance and sale of the Shares 
as contemplated by the Stock Purchase Agreement; and

        7.      Except as disclosed in the documents referred to in Section 4.4 
of the Stock Purchase Agreement, there is no action, suit, proceeding, inquiry 
or investigation before or by any court, public board or body pending or, to 
the best of our knowledge, threatened against or affecting the Company or any 
of its subsidiaries, wherein an unfavorable decision, ruling or finding would 
have a material adverse effect on the properties, business, condition 
(financial or other), results of operations or prospects of the Company and its 
subsidiaries taken as a whole or the transactions contemplated by the Stock 
Purchase Agreement or any of the documents contemplated thereby or which would 
adversely affect the validity or enforceability of, or the authority or ability 
of the Company to perform its obligations under, the Stock Purchase Agreement 
or any of such other documents.

        Prior to ____________, 1995, we participated in conferences with 
officers and other representatives of the Company at which the contents of the 
Private Placement Memorandum, and related matters were discussed. There can be 
no assurance that all possible material facts as to the Company were disclosed 
in such conferences. We have not undertaken to verify independently the 
statements made in the documents and conferences referred to above and 
therefore are not passing upon or assuming any responsibility for the accuracy, 
completeness or fairness of the statements contained in the Private Placement 
Memorandum but we hereby confirm to you, on the basis of the foregoing, that no 
facts have come to our attention which lead us to believe that the Private 
Placement Memorandum and the exhibits thereto (except for the financial 
statements and schedules and statistical data, including the schedules and 
notes to the financial statements included therein, as to which no statement is 
made), as of its date and as of the date hereof, contained any untrue statement 
of a material fact or omitted to state a material fact required to be stated 
therein or necessary to make the statements therein, in light of the 
circumstances under which they were made, not misleading.

This opinion is rendered to you and is solely for your benefit in your capacity 
as placement agent for the shares of Common Stock, and may not be relied upon 
by you for any other purpose, or furnished to, quoted to or relied upon by any 
other person for any purpose without our prior written consent.

                                        Very truly yours,

                                        GOODWIN, PROCTER & HOAR
