         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.   MANAGEMENT STATEMENT

In the opinion of the Company's management, the accompanying unaudited condensed
consolidated financial statements contain all adjustments (consisting of only
normal recurring accruals) necessary to present fairly the financial position as
of September 30, 1997 and December 31, 1996 and the results of operations for
the three-month and nine-month periods ended September 30, 1997 and 1996.

The results of operations for the three-month and nine-month periods ended
September 30, 1997 are not necessarily indicative of the results to be expected
for the full year.

2.   MARKETABLE SECURITIES

The Company has classified its marketable securities as available for sale and,
accordingly, carries such securities at aggregate fair value. At September 30,
1997 and December 31, 1996, the Company's marketable securities consisted of the

</TABLE>


At September 30, 1997, approximately $22,322,000 of investments in marketable
securities had contractual maturities of one year or less. Realized gains and
losses on sales of marketable securities were not material during the quarter
ended September 30, 1997; the net unrealized loss of $52,143 is included in
stockholders' equity.

3.   HOECHST-ARIAD GENOMICS CENTER, LLC

In March 1997, the Company entered into an agreement which established a 50/50
joint venture with Hoechst Marion Roussel, Inc. ("HMR") to pursue functional
genomics (the "1997 HMR Genomics Agreement") with the goal of identifying novel
therapeutic proteins and small-molecule drug targets. The joint venture, named
the Hoechst-ARIAD Genomics Center, LLC (the "Genomics Center"), is located at
the Company's research facilities in Cambridge, Massachusetts. Under the terms
of the 1997 HMR Genomics Agreement, the Company and HMR agreed to commit up to
$85,000,000 to the



                                       4

<PAGE>   7



establishment of the Genomics Center and its first five years of operation. The
Company and HMR will jointly fund $78,500,000 of operating and related costs,
and ARIAD will fund up to $6,500,000 in leasehold improvements and equipment.
HMR committed to provide ARIAD with capital adequate to fund ARIAD's share of
such costs through the purchase of up to $49,000,000 of ARIAD series B preferred
stock over the five-year period, including an initial investment of $24,000,000,
which was completed in March 1997.

The Company also entered into agreements with the Genomics Center to provide
research and administrative services (the "Services Agreements") to the
Genomics Center on a cost reimbursement basis. ARIAD's costs of providing the
research and administrative services to the Genomics Center are charged to
research and development expense and general and administrative expense in the
consolidated financial statements. Under the Services Agreements, ARIAD bills
the Genomics Center for 100% of its costs of providing the research and
administrative services; however, because ARIAD is providing 50% of the funding
of the Genomics Center, ARIAD recognizes as revenue only 50% of the costs.
ARIAD accounts for its investment in the Genomics Center using the equity
method. Revenue recognized pursuant to the Services Agreements amounted to
$696,000 for the nine-month period ended September 30, 1997. Costs incurred in
the development of the joint venture are being amortized over a five-year
period beginning April 1, 1997.

4.   COMMITMENTS

In March 1997, in connection with the formation of the Genomics Center, the
Company entered into a collaborative agreement with Incyte Pharmaceuticals, Inc.
("Incyte") providing access to the LifeSeq (R) Database. As required by the
agreement, in order to secure the Company's obligation for installation and
payment of certain access fees, the Company obtained an irrevocable standby
letter of credit in the amount of $3,000,000 to the benefit of Incyte, which
expires on January 10, 1998.

5.   NET LOSS PER SHARE

The shares of series B convertible preferred stock issued in March 1997 are
common stock equivalents, but have been excluded from the computation of net
loss per share because their effect is not dilutive.

6.   NEW ACCOUNTING PRONOUNCEMENT

The Company will adopt Statement of Financial Accounting Standards ("SFAS") 
No. 128, "Earnings Per Share," in the fourth quarter of 1997, as required. The
standard specifies the computation, presentation and disclosure requirements for
earnings per share. The Company will continue to apply Accounting Principle
Board Opinion No. 15, "Earnings Per Share," until the adoption of SFAS No. 128.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
          CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

ARIAD Pharmaceuticals, Inc. (the "Company" or "ARIAD") is engaged in the
discovery and development of novel pharmaceuticals based on signal transduction
pathways and the genes that regulate them. The Company is currently focusing its
efforts in three areas: (i) the development of orally administered drugs to
block intracellular signal transduction pathways that are critical to major
diseases such as osteoporosis, allergy/asthma and immune-related disorders; (ii)
the development of a system to regulate gene therapy using orally administered
drugs; and (iii) the identification of new small-molecule drug targets and
therapeutic proteins through functional genomics. ARIAD has assembled a broad
portfolio of advanced technologies for the identification, validation and
optimization of novel drugs. These technologies have been integrated into a drug
discovery platform that, in conjunction with the Company's expertise in signal
transduction, forms the basis for multiple business opportunities, each with a
diversity of potential products. In each of its three areas of drug discovery,
the Company has entered into a strategic alliance with a collaborator to
complement its drug discovery technologies or to support its commercialization
efforts.

Since its inception in 1991, the Company has devoted substantially all of its
resources to its research and development programs. The Company receives no
revenue from the sale of pharmaceutical products, and substantially all revenue
to date has been received in connection with the Company's research
collaborations. The Company has not been profitable since inception and expects
to incur substantial losses for the foreseeable future, primarily due to the
expansion of its research and development programs, including the establishment
of the Hoechst-ARIAD Genomics Center, LLC (the "Genomics Center"). The Company
expects that losses will fluctuate from quarter to quarter and that such
fluctuations may be substantial. As of September 30, 1997, the Company had an
accumulated deficit of $61,335,000.

collaborative research and development agreement with Hoechst Marion Roussel,
Inc. ("HMR") (the "1995 HMR Osteoporosis Agreement"), government-sponsored
research grants and, beginning in 1997, research revenue recognized for services
provided to the Genomics Center. The increase in research revenue of $127,000 is
the result of services provided to the Genomics Center offset partially by
decreased activity under government-sponsored research grants. Research revenue
resulting from the services agreements with the Genomics Center is expected to
increase over the next three years.

Interest income increased to $511,000 for the quarter ended September 30, 1997,
up $146,000 from $365,000 for the same period in 1996 primarily as a result of
higher levels of funds invested.

OPERATING EXPENSES

Research and development expenses increased to $4,667,000 for the quarter ended
September 30, 1997 from $3,831,000 for the same period in 1996 due to increased
expenses incurred in the regulated gene therapy program, including manufacturing
development and other preclinical development costs, research services provided
to the Genomics Center and increased research activity under the 1995 HMR
Osteoporosis Agreement. The Company expects its research and development
expenses to increase significantly as a result of research services to be
provided to the Genomics Center, as well as increased manufacturing and other
preclinical development costs associated with advanced preclinical studies and
planned clinical studies of its first gene therapy drug candidate.

General and administrative expenses increased to $592,000 for the quarter ended
September 30, 1997 from $459,000 for the corresponding period in 1996 primarily
due to increased expenses in connection with the formation of the Genomics
Center and other administrative expenses.

The Company incurred interest expense of $153,000 for the quarter ended
September 30, 1997 compared to $64,000 for the corresponding period in 1996. The
increase is due to a higher level of long-term debt during the period.

OPERATING RESULTS

The Company incurred losses of $2,664,000 for the quarter ended September 30,
1997 and $1,880,000 for the corresponding period in 1996, or $.14 and $.10 per
share, respectively. The Company expects that substantial operating losses will
continue for several more years, will increase as its activities expand and
increased research services are provided to the Genomics Center and will
fluctuate as a result of differences in the timing and composition of revenue
earned and expenses incurred.

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED WITH THE NINE MONTHS ENDED
SEPTEMBER 30, 1996

REVENUE

Revenue for the nine months ended September 30, 1997 was $8,028,000 compared to
$7,263,000 for the corresponding period in 1996. Research revenue earned during
this period in 1997 increased by $437,000 over 1996 principally as a result of
services provided to the Genomics Center. Interest income for the nine months
ended September 30, 1997 increased by $327,000 over the corresponding period in
1996 primarily as a result of a higher level of funds invested.

OPERATING EXPENSES

Research and development expenses increased to $13,197,000 for the nine months
ended September 30, 1997, up 18% from $11,219,000 for the corresponding period
in 1996, primarily due to increased expenses incurred in the regulated gene
therapy program, including manufacturing development and other preclinical
development costs, research services provided to the Genomics Center and
increased research activity as a result of the 1995 HMR Osteoporosis Agreement.

General and administrative expenses increased by 25% to $2,076,000 for the nine
months ended September 30, 1997 compared to $1,661,000 for the corresponding
period in 1996, primarily due to increased expenses in connection with the
formation of the Genomics Center, the joint venture with Genovo Inc. and other
administrative expenses.

The Company incurred interest expense of $264,000 for the nine months ended
September 30, 1997 compared to $202,000 for the corresponding period in 1996 as
a result of a higher level of long-term debt.

OPERATING RESULTS

The Company incurred losses of $7,510,000 for the nine months ended
September 30, 1997 and $5,820,000 for the corresponding period in 1996, or $.39
and $.31 per share, respectively. The Company expects that substantial operating
losses will continue for several more years, will increase as its activities
expand and increased research services are provided to

the Genomics Center and will fluctuate as a result of differences in the timing
and composition of revenue earned and expenses incurred.


LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its operations and investments in property and
equipment primarily through the private placement and public offering of its
securities, including, most recently, the sale of series B preferred stock to
HMR in connection with the formation of the Genomics Center in March 1997, the
increase in June 1997 of its long-term debt and, commencing in April 1997, the
services agreements with the Genomics Center. Other sources of funds have
included sale/leaseback and capital lease transactions, interest income,
government-sponsored research grants and research revenue under the 1995 HMR
Osteoporosis Agreement.

As of September 30, 1997, the Company had cash, cash equivalents and marketable
securities totaling $33,152,000 and working capital of $22,581,000 compared to
cash, cash equivalents and marketable securities totaling $15,702,000 and
working capital amounting to $11,902,000 at December 31, 1996.

The primary uses of cash during the nine months ended September 30, 1997 were
$2,214,000 to finance the Company's operations and working capital requirements,
$7,110,000 to purchase laboratory equipment and to renovate space for the
Genomics Center, $1,328,000 to repay long-term debt, $1,256,000 for investment
in the Genomics Center and $1,940,000 to acquire licensed technology and
patents, including the purchase, in July 1997, of pending patent applications
and related intellectual property rights from Mitotix, Inc. The primary
sources of cash during the nine months ended September 30, 1997 were $24,000,000
from the issuance of series B preferred stock to HMR, $5,000,000 of research
funding from the 1995 HMR Osteoporosis Agreement, $6,000,000 in additional
long-term debt and $2,103,000 in advances from the Genomics Center.

In February 1997, the Company began renovation of approximately 35,000 square
feet of previously leased space to provide laboratories and offices for the
Genomics Center and to expand existing chemistry and pharmacology laboratories.
The leasehold improvements were substantially completed in October 1997 at an
aggregate cost of approximately $5,500,000.

In June 1997, the Company amended its existing debt agreement with its principal
bank and borrowed $6,000,000. The five-year bank term note bears interest at
prime plus 1% and is repayable in monthly installments of $100,000, commencing
August 1, 1997. In September 1997, the Company entered into a master lease
credit agreement with an equipment lessor providing up to $5,000,000 in
equipment financing. The lease agreement is classified as an operating lease and
has a term of five years with a lease renewal or purchase option at the end of
the term. Through September 30, 1997, the Company placed equipment with a cost
of $1,148,000 under the agreement.


                                       9

<PAGE>   12



The Company has substantial fixed commitments under various research and
licensing agreements, consulting and employment agreements, lease agreements,
long-term debt instruments and funding obligations related to the operations of
the Genomics Center. The Company will require substantial additional funding for
its research and product development programs, for operating expenses, for the
pursuit of regulatory clearances and for the manufacturing, sales and marketing
of its products. Adequate funds for these purposes, whether obtained through
financial markets or collaborative or other arrangements with corporate
partners, from public or private sales of equity securities, debt securities or
convertible securities or from other sources, may not be available when needed
or on terms acceptable to the Company.

The Company believes that its available cash and existing sources of funding
will be adequate to satisfy its capital and operating requirements through 1998.
However, there can be no assurance that changes in the Company's research and
development plans or other events affecting the Company's operating expenses
will not result in the Company depleting its funds earlier.

<PAGE>   3

                           ARTICLE II - LICENSE GRANT

     2.1 ARIAD hereby grants to Mitotix and Mitotix hereby accepts [*]
royalty-free license [*] in the Field under the Invention, the Licensed Patents
and Licensed Know-How to develop, use, make, have made, sell and import
Diagnostic Products.

     2.2 Notwithstanding the foregoing, ARIAD hereby retains [*] the Licensed
Patents and the Licensed Know-How to develop, use, make, have made, sell and
import Diagnostic Products (i) for use in connection with therapeutic or
prophylactic products that are developed, manufactured, imported or sold by
ARIAD and/or parties licensing such therapeutic or prophylactic products from
ARIAD ("ARIAD Therapeutic Products"), (ii) for use in determining how to utilize
(e.g., dosing regimen or drug monitoring) ARIAD Therapeutic Products to treat a
particular disease or patient, or (iii) for monitoring the effect of ARIAD
Therapeutic Products. The foregoing right reserved to ARIAD shall not include
the right to develop, use, make, have made, sell and import Diagnostic Products
to generally determine the presence or absence of, or predisposition to, a
disease state independent of a determination relative to the use of ARIAD
Therapeutic Products.

     2.3 The license granted to Mitotix under Paragraph 2.1 of this article
shall include the right to grant sublicenses of no greater scope than the
license granted to Mitotix hereunder.

     2.4 In the event that prosecution of any of the Licensed Patents leads to
the issuance of claims directed to [*] as defined in the Technology Purchase
Agreement), ARIAD covenants that it will not enforce such claims against Mitotix
or any licensee or sublicensee of Mitotix (i) to which Mitotix licenses
technology developed by Mitotix which utilizes such an assay, or (ii) with which
Mitotix is collaborating on a program or project which utilizes such an assay.
Any such licensee or sublicensee of Mitotix may rely on ARIAD's covenant as an
intended third party 


                                       3


<PAGE>   4

beneficiary. No license or covenant to refrain from enforcing any other patent
rights owned or licensed by ARIAD is hereby expressed or implied.

                ARTICLE III - PROPRIETARY POSITION; INFRINGEMENT

     3.1 ARIAD shall be responsible, [*] for the preparation, filing,
prosecution and maintenance of all patent applications and patents included in
the Licensed Patents and shall use commercially reasonable efforts to obtain the
issuance of [*] claims in the Field in such applications. ARIAD shall keep
Mitotix reasonably informed on a timely basis as to the status of the patent
applications and the patents. ARIAD shall provide advance written notice to
Mitotix if, for any reason, it elects not to continue the preparation, filing,
prosecution or maintenance of any of the patent applications or patents included
in the Licensed Patents, [*].

     3.2 If at any time either party becomes aware of any infringement by any
commercial third parties of any Licensed Patent (excluding claims of [*] as
defined in the Purchase Agreement) in the Field, such party shall provide the
other party with the available evidence, if any, of such infringement.

     3.3 If at any time any third party shall infringe any unexpired Licensed
Patent in the Field and Mitotix shall give notice in writing to ARIAD of the
existence of such infringement, then ARIAD shall have the right, but not the
obligation, in the exercise of its commercially reasonable judgment, to take
action to abate such infringement. [*] In the event ARIAD does not take such
actions, then, subject to ARIAD's right set forth in Section 3.4, Mitotix may at
its election bring suit in its own name or in the name of ARIAD against such
infringer, all at the expense of Mitotix. ARIAD shall execute such legal papers
necessary for the prosecution of such suit as may be reasonably requested by
Mitotix. Mitotix shall be entitled to receive and retain all recoveries of
compensatory damages, in any form, from any suit so brought by


                                       4


<PAGE>   5



Mitotix, except that ARIAD and Mitotix shall be entitled to receive an amount
equal to their reasonable expenses in prosecuting the suit (in the case of
Mitotix) or providing any cooperation (in the case of ARIAD) under this section.
In any suit brought hereunder, (i) the parties hereto shall each cooperate in
the conduct of any suit hereunder at their own expense, (ii) the parties shall
share equally any recoveries, in any form, other than compensatory damages, and
(iii) if the party bringing suit decides to enter into a settlement of the suit,
such settlement shall require the consent of the other party hereto, which shall
not be unreasonably withheld or delayed. Notwithstanding the foregoing, [*]
except that ARIAD and Mitotix shall be entitled to receive an amount equal to
their reasonable expenses in connection with such suit. In all events, if
damages or the proceeds of settlement are not sufficient to pay the expenses of
both ARIAD and Mitotix as provided above, the available amount shall be used to
pay such expenses on a pro-rata basis.

     3.4 If Mitotix wishes to bring any suit pursuant to Section 3.3, it shall
give ARIAD thirty (30) days' written notice. Notwithstanding the foregoing,
ARIAD shall have the right to deny Mitotix the right to bring any such suit
proposed to be brought by Mitotix under Section 3.3 above by written notice to
Mitotix within such thirty (30) day period if ARIAD in good faith believes that
the commencement or prosecution of any such suit will create an unreasonable
risk of invalidating or otherwise jeopardizing the value of the Licensed
Patents.

                            ARTICLE IV - TERMINATION

     If any material terms or conditions of this Agreement are breached by a
party (the "breaching party") and such breach is not corrected within sixty (60)
days after written notice thereof is given to the breaching party by the
non-breaching party, then the non-breaching party shall have the option to
terminate this Agreement by giving written notice thereof to the breaching
party.

[*]

                       ARTICLE VI - STATUS OF THE PARTIES

     No partnership, joint venture, agency or employer-employee relationship is
created hereby and neither party is authorized or empowered to make any
statement, contract, warranty, representation or commitment on behalf of the
other.

                    ARTICLE VII - INDEMNIFICATION; DISCLAIMER

     7.1 Except to the extent that any claims or causes of action are based upon
[*] Mitotix shall defend, indemnify and hold ARIAD harmless against any and all
liability, damage, loss, cost or expense resulting from any claim, suit or other
action arising out of or based on Mitotix's (or its Affiliates' or
sublicensees') development, manufacture, use or sale of any Diagnostic Products
licensed hereunder. ARIAD shall promptly notify Mitotix of any such claim of
which it has actual notice and shall cooperate with Mitotix, at Mitotix's sole
expense, in the defense thereof, but the omission to so notify Mitotix will not
relieve Mitotix from any liability it will have to ARIAD other than under
Section 7.1 or to the extent Mitotix is not actually prejudiced as a result of
such omission. The parties shall use joint counsel, selected jointly by them, in
the defense of any such claim, unless ARIAD, in the exercise of commercially
reasonable judgment, determines that it needs to retain separate counsel because
of an actual or potential conflict of interest between ARIAD and Mitotix. [*]

     7.2 EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, NEITHER PARTY
MAKES ANY WARRANTY WITH RESPECT TO ANY TECHNOLOGY, GOODS, SERVICES, RIGHTS OR
OTHER SUBJECT MATTER OF THIS AGREEMENT AND HEREBY DISCLAIMS WARRANTIES OF

                           ARTICLE IX - MISCELLANEOUS

     9.1 This Agreement shall be governed by and construed in accordance with
the internal laws of The Commonwealth of Massachusetts. Any controversy, dispute
or claim arising out of or in connection with this Agreement, or the breach,
termination or validity hereof, shall be settled by final and binding
arbitration to be conducted by an arbitration tribunal in Boston, Massachusetts
pursuant to the rules of the American Arbitration Association. The arbitration
tribunal shall consist of three arbitrators. The party initiating arbitration
shall nominate one arbitrator in the request for arbitration and the other party
shall nominate a second in the answer thereto within thirty (30) days of receipt
of the request. The two arbitrators so


                                       7


<PAGE>   8

named will then jointly appoint the third arbitrator. If the answering party
fails to nominate its arbitrator within the thirty (30) day period, or if the
arbitrators named by the parties fail to agree on the third arbitrator within
sixty (60) days, the office of the American Arbitration Association in Boston,
Massachusetts shall make the necessary appointments of such arbitrator(s). Each
party shall pay the costs of its respective arbitrator, and the parties shall
share equally the costs of the third arbitrator. The decision or award of the
arbitration tribunal (by a majority determination, or if there is no majority,
then by the determination of the third arbitrator, if any) shall be final, and
judgment upon such decision or award may be entered in any competent court or
application may be made to any competent court for judicial acceptance of such
decision or award and an order of enforcement. In the event of any procedural
matter not covered by the aforesaid rules, the procedural law of The
Commonwealth of Massachusetts shall govern.

     9.2 This Agreement, in conjunction with the Technology Purchase Agreement,
constitutes the entire Agreement between the parties hereto with respect to the
subject matter hereof and as such supersedes all previous written and oral
negotiations, agreements, contracts, representations, letters of intent,
understandings and commitments with respect thereto. This Agreement may be
modified, discharged, amended, or extended only by a writing signed by a duly
authorized representative of the parties.

     9.3 Should any court of competent jurisdiction later consider any portion
of this Agreement to be invalid, illegal or unenforceable, it shall be
considered severed from this Agreement. All other provisions, rights or
obligations shall continue without regard to the severed provision, provided
that the remaining provisions of this Agreement are in accordance with the
intention of the parties.

                     TECHNOLOGY PURCHASE AND SALE AGREEMENT

     This Technology Purchase Agreement and Sale Agreement (the "Agreement") is
entered into as of July 17, 1997 by and between ARIAD Pharmaceuticals, Inc. (the
"Buyer") and Mitotix, Inc. (the "Seller").

     WHEREAS, the Seller desires to sell and the Buyer desires to buy the right,
title and interest of the Seller in certain intellectual property, patent
applications, know-how and reagents relating to the inventions disclosed in the
Patents (as hereinafter defined), except as excluded by Section 1.05 hereof (the
"Invention").

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained in this Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows:

     1. PURCHASE AND SALE OF ASSETS.

     1.01 TRANSFERRED ASSETS. Upon the terms and conditions set forth in this
Agreement, at the Closing (as defined in Section 1.06) the Seller shall transfer
to the Buyer good and valid title to the Patents (as defined below in Section
1.01(a)) and all of its right, title and interest in and to the Know-How and
Reagents (as defined below in Sections 1.01(b) and (c), respectively). The
Patents, Know-How and Reagents shall hereinafter be collectively referred to as
the "Transferred Assets". The Transferred Assets shall consist of:

     (a) The patent applications listed on SCHEDULE 2.05, the prosecution files
for such patent applications (including, without limitation, all drafts, notes,
drawings or figures, official correspondence with patent offices, other
correspondence and copies of cited references, copies of which the Seller may
retain), and all intellectual property rights (other than rights pertaining to
[*] as hereinafter defined) in such applications, including without limitation
the right to claim the priority benefit thereof and to prosecute and to enforce
any patents arising therefrom (collectively, the "Patents").


<PAGE>   2


     (b) All laboratory notebooks and other primary data, research results,
records and documentation, research plans, proposals, conclusions, know-how,
specifications and information, to the extent any of the foregoing are recorded
in any tangible form (including, without limitation, gels, photographs,
print-outs, electronic files and paper documents), which are owned by, licensed
to or in the possession of the Seller and which relate to the discovery of or
are necessary or materially useful for the practice of the Invention, the
Patents or the Reagents, and all intellectual and tangible property rights in
the foregoing, including the right to file additional patent applications based
thereon (collectively, the "Know-How").

     (c) The reagents listed on, and in the quantities listed on, SCHEDULE 2.04
attached hereto (the "Reagents").

     Except as set forth in this Agreement, the Transferred Assets shall be
transferred on an "AS IS" basis. The Seller shall transfer the Transferred
Assets to the Buyer pursuant to a Bill of Sale in substantially the form of
EXHIBIT 1.01A attached hereto (the "Bill of Sale") and an Assignment of Patents
substantially in the form of EXHIBIT 1.01B attached hereto (the "Patent
Assignment").

     1.02 NO LIABILITIES. The Buyer shall not assume any liabilities of the
Seller in connection with the Invention, the Transferred Assets or the
transactions contemplated by this Agreement.

     1.03 CONSIDERATION FOR THE TRANSFERRED ASSETS. In consideration for the
transfer of the Transferred Assets, upon the terms and subject to the conditions
set forth in this Agreement, the Buyer shall pay the Seller an aggregate sum of
[*] (the "Purchase Price") payable as follows:


     (a) [*] shall be paid at the Closing (the "Closing Payment"); and

     (b) An additional [*] shall be paid on each of the dates which is [*] after
the Closing Date (as defined in Section 1.07) (the "Installments").

     The Closing Payment and each of the Installments shall be made by wire
transfer to an account designated by the Seller.

     1.04 LICENSE. As additional consideration for the Transferred Assets,
effective upon the completion of the Closing, the parties shall enter into a
license agreement granting to the Seller a [*] license, with the right to grant
sublicenses, to develop, use, make, have made, sell and import Diagnostic
Products (as hereinafter defined) using the Invention, the Patents and the
Know-How (the "License"). Notwithstanding the foregoing, the License shall
retain for the Buyer, the [*] right, [*] to develop, use, make, have made, sell
and import Diagnostic Products (i) for use in connection with therapeutic or
prophylactic products that are developed, manufactured, imported or sold by the
Buyer and/or parties licensing such therapeutic or prophylactic products from
the Buyer ("Buyer Therapeutic Products"), (ii) for use in determining how to
utilize (e.g., dosing regimen or drug monitoring) Buyer Therapeutic Products to
treat a particular disease or patient, or (iii) for monitoring the effect of
Buyer Therapeutic Products. The 


                                       2


<PAGE>   3

foregoing right reserved to the Buyer shall not include the right to develop,
use, make, have made, sell and import Diagnostic Products to generally determine
the presence or absence of, or predisposition to, a disease state independent of
a determination relative to the use of Buyer Therapeutic Products. For purposes
of this Agreement and the License, "Diagnostic Products" shall mean products
which are intended to monitor the course of disease or therapy in humans,
predict, detect or identify a disease in humans, or determine the outcome of a
pathological condition in humans.

     1.05 EXCLUSION OF [*]. For the purpose of this Agreement, [*] and all uses
disclosed for any of the foregoing. The parties expressly agree that [*] is not
included within the subject matter transferred and assigned hereunder and is
expressly excluded from the definitions of the Invention, the Patents and the
Know-How. The Seller shall have an unrestricted right to prosecute claims
relating to [*].

     1.06 FURTHER ASSURANCES. At any time and from time to time after the date
hereof, at the request of the Buyer and without further consideration, the
Seller will execute and deliver such other instruments of sale, transfer,
conveyance, assignment and confirmation as may be reasonably requested in order
to more effectively transfer, convey and assign to the Buyer and to confirm the
Buyer's title to the Transferred Assets.

     1.07 CLOSING. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Mintz, Levin, Cohn,
Ferris, Glovsky and Popeo, P.C., One Financial Center, Boston, Massachusetts
contemporaneously with the execution of this Agreement. At the Closing:

     the inventions claimed in the Patents and any additional records
     corroborating the foregoing. The Seller may retain copies of the Know-How
     in microfiche or other format. The original copies of the Know-How and
     Patents transferred to the Buyer shall be retained by the Buyer and made
     available to the Seller for use in connection with the Seller's rights
     under the License, for the prosecution, defense, maintenance or enforcement
     of patent applications and patents other than the Patents, and for all
     purposes unrelated to the Invention or the Transferred Assets. [*]

parties hereto.

     6.04 WAIVERS AND CONSENTS. No failure or delay by a party hereto in

power or remedy of the party. No single or partial exercise of any right, power

executed by the party entitled to the benefits of such terms or provisions. No
such waiver or consent shall be deemed to be or shall constitute a waiver or
consent with respect to any other terms or provisions of this Agreement, whether

specific instance and for the purpose for which it was given, and shall not
constitute a continuing waiver or consent.

     6.05 ASSIGNMENT. [*]

connection with this Agreement, or the breach, termination or validity hereof,
shall be settled by final and binding arbitration to be conducted by an

govern.

     6.07 GOVERNING LAW. This Agreement and the rights and obligations of the
parties hereunder shall be construed in accordance with and governed by the

conflict of law principles thereof.

     6.08 SEVERABILITY. In the event that any court of competent jurisdiction
shall finally determine that any provision, or any portion thereof, contained in
this Agreement shall be void or unenforceable in any respect, then such
provision shall be deemed limited to the extent that such court determines it
enforceable, and as so limited shall remain in full force and effect. In the


                                       8


<PAGE>   9

event that such court shall determine any such provision, or portion thereof,
