require any consent under or be in conflict with or


constitute, with or without the passage of time or the giving of notice or both,
either a violation or default under any such provision, instrument, Applicable

     ---------------------------------
with a true and complete copy of each report, schedule, registration statement
and definitive proxy statement filed by the Company with the Securities and
Exchange Commission (the "SEC") since December 31, 1998 (the "SEC Documents"),
which are all the documents that the Company has been required to file with the
SEC during such period. As of their respective dates, the SEC Documents complied

Act"), or the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
as applicable, and the rules and regulations of the SEC thereunder, and none of
the SEC Documents contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading. The financial statements of the Company included in the
SEC Documents are complete in all material respects and were prepared in

decrees and orders, and possesses all governmental franchises, permits and
consents, and has made all governmental filings and declarations, applicable to

such Applicable Laws, decrees and orders relating to pharmaceutical, antitrust,
consumer protection, currency exchange, environmental protection, equal
opportunity, health, occupational safety, pension, securities and trading-with-
the-enemy matters), the failure to comply with which would, individually or in
the aggregate, have a Material Adverse Effect. The Company has not received any
notification of any asserted present or past unremedied failure by the Company

4.   Representations and Warranties of Alkermes.  Alkermes hereby represents
     ------------------------------------------
and warrants to the Company as follows:

4.1  Authorization.  All acts and conditions necessary for the authorization,
     -------------
execution, delivery and consummation by Alkermes of this Agreement and the
transactions contemplated hereby have been, or will be prior to the Closing,
taken, performed and obtained. This Agreement constitutes a valid and legally
binding obligation of Alkermes, enforceable in accordance with its terms, except
as (a) such enforceability may be limited by bankruptcy, insolvency or similar
laws affecting creditors' rights generally and (b) the availability of equitable
remedies may be limited by equitable principles of general applicability.
Alkermes has full power and authority to execute, deliver and perform its
obligations under this Agreement and to own the Shares and the Warrants. The
execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby will not conflict with or constitute a
violation or default under any provision of the charter or bylaws of Alkermes,
or of any material agreement, indenture or other instrument to which Alkermes is
a party, or by which it or its properties or assets are bound, or of any order,
judgment or decree against or binding upon Alkermes.

4.2  Exemption From Registration.  Alkermes has been advised that none of the
     ---------------------------
Shares and Warrants to be issued to Alkermes hereunder or the Warrant Shares to
be issued upon the exercise of the Warrants are being registered under the
Securities Act and the rules and regulations of the SEC promulgated thereunder,
or applicable state securities laws, but are being offered and sold pursuant to
exemptions from such laws, and that the Company's reliance upon such exemptions
is predicated in part on Alkermes' representations contained herein.

4.3  Purchase Entirely for Own Account.  The Shares, Warrants and the Warrant
     ---------------------------------
Shares to be received by Alkermes will be acquired for investment for Alkermes'
own account, not as a nominee or agent, and not with a view to the distribution
of any part thereof, and Alkermes does not have any present intention of
selling, granting any participation in, or otherwise distributing the same in a
manner contrary to the Securities Act or any applicable state


securities law. Alkermes does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to such
person or to any third person with respect to any of the Shares or the Warrants.

4.4  Access to Information.  Alkermes has been furnished such information as
     ---------------------
it has requested to evaluate an investment in the Shares, the Warrants and the
Warrant Shares.  Alkermes has been given the opportunity to ask questions of and
receive answers from representatives of the Company concerning the terms and
conditions of the offering of the Shares, the Warrants and the Warrant Shares
and to obtain any additional information, to the extent reasonably available.

4.5  Restricted Securities.  Alkermes acknowledges that none of the Shares, the
     ---------------------
Warrants or the Warrant Shares to be issued to Alkermes hereunder have been
registered under the Securities Act and that all of such Shares, Warrants and
the Warrant Shares are characterized under the Securities Act as "restricted
securities" and therefore cannot be sold or transferred unless subsequently
registered under the Securities Act or an exemption from such registration is
available.  In this connection, Alkermes represents that it is familiar with
Rule 144 of the SEC, as presently in effect, and understands the resale
limitations imposed thereby and by the Securities Act.

4.6  Legends.  It is understood that the certificates evidencing the Shares,
     -------
the Warrants or the Warrant Shares may bear legends in substantially the
following form:

          The securities evidenced by this certificate have not been registered
          under the Securities Act of 1933, as  amended (the "Act"), or
          applicable state securities law, and no interest therein may be sold,
          distributed, assigned, offered, pledged or otherwise transferred
          unless (i) there is an effective registration statement  under the Act
          and applicable state securities laws covering any such transaction
          involving said securities, (ii) this corporation receives an opinion
          of legal counsel for the holder of these securities reasonably
          satisfactory to this corporation stating that such transaction is
          exempt from registration or (iii) this  corporation otherwise
          satisfies itself that such transaction is exempt from registration.

under the Securities Act to effect registration of shares of the Shares issued
to Alkermes hereunder (the "Registrable Securities") for resale by Alkermes. The
Company will use its best efforts to effect the registration and qualification
of the Registrable Securities and in connection therewith, the Company shall:

     (a)  prepare and file with the SEC within ninety (90) days of the date of
     the Closing, and use its best efforts to cause to become effective as soon
     as possible thereafter, a registration statement on Form S-3 (or any
     successor or other appropriate form) under the Securities Act permitting
     the Registrable Securities to be offered for resale by Alkermes;

     (b)  prepare and file with the SEC such amendments and supplements to such
     registration statement and the prospectus used in connection therewith, as
     may be necessary to keep such registration statement effective and to
     comply with the provisions of the Securities Act with respect to the
     disposition of all Registrable Securities until the earlier of such time as
     all of such Registrable Securities have been disposed of in accordance with
     the intended methods of disposition by Alkermes set forth in such
     registration statement or until such time as Alkermes may dispose of such
     Registrable Securities pursuant to Rule 144(k) under the Securities Act;

     (c)  furnish to Alkermes, or each successor who is a holder of Registrable
     Securities, and to any underwriter of such Registrable Securities; such
     number of conformed copies of such registration statement and of each such
     amendment and supplement thereto, such number of copies of the prospectus
     included in such registration statement (including each preliminary
     prospectus and any summary prospectus) or filed under Rule 424(b) or Rule
     424(c) under the Securities Act, in conformity with the requirements of the
     Securities Act, such documents incorporated by reference in such
     registration statement or prospectus, and such other documents, as Alkermes
     or any such underwriter may reasonably request;

     (d)  use its best efforts (i) to list all Registrable Securities covered by
     such registration statement on the Nasdaq National Market, and (ii) to
     register or qualify all Registrable Securities covered by such registration
     statement under such "blue sky" or other securities law of such
     jurisdictions as Alkermes or any underwriter of such Registrable Securities


     will reasonably request, and do any and all other acts and things which may
     be necessary to enable Alkermes or any underwriter to consummate the
     disposition in such jurisdictions of the Registrable Securities covered by
     such registration statement, except that the Company shall not for any such
     purpose be required to qualify generally to do business as a foreign
     corporation in any jurisdiction wherein it is not so qualified, or to
     subject itself to taxation in any such jurisdiction or to consent to
     general service of process in any such jurisdiction;

     (e)  promptly notify Alkermes, at any time of the occurrence, of any event
     as a result of which the portion of the prospectus included in such
     registration statement which contains information furnished by or relating
     to the Company, as then in effect, includes an untrue statement of a
     material fact or omits to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading in the
     light of the circumstances then existing (each such event, a "Material
     Event") and, at the request of Alkermes, prepare and furnish to Alkermes a
     reasonable number of copies of a supplement to, or an amendment of, such
     prospectus as may be necessary so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus will not include
     an untrue statement of a material fact or omit to state a material fact
     required to be stated therein or necessary to make the statements therein
     not misleading in the light of the circumstances then existing; and

     (f)  The Company may require Alkermes to furnish the Company such
     information regarding itself and the distribution of such Registrable
     Securities as the Company may from time to time reasonably request in
     writing and as will be required by law or by the SEC in connection with any
     registration.

     -------------------------------
will be subject to applicable provisions of the Securities Act and the Exchange
Act.

7.3  Exchange Act Reports and Availability of Rule 144.  During the

period from the date of the Closing until the date which is five (5) years
following the date of the Closing, the Company shall use its best efforts to (i)
timely file all reports required to be filed by the Company under the Exchange
Act and (ii) take such other action and coordinate with Alkermes to ensure that
Rule 144 shall be available to Alkermes for the purpose of disposing of their
Registrable Securities.

7.4  Discontinuation of Disposition of Registrable Securities. Alkermes will,
     --------------------------------------------------------
upon receipt of any notice from the Company of the occurrence of any Material
Event, discontinue disposition of Registrable Securities pursuant to the
registration statement covering such Registrable Securities until Alkermes'
receipt of (x) the copies of the supplemented or amended prospectus contemplated
by Section 7.1(e) above or (y) notice from the Company that no such supplemented
or amended prospectus is required, which supplemented or amended prospectus
shall be made available or notice shall be delivered to Alkermes as soon as
practicable but in any event within thirty (30) days of receipt by Alkermes of
the notice of a Material Event; provided, however, that the Company shall not
                                --------  -------
give notice of a Material Event: (i) beginning when Alkermes notifies the
Company that marketing efforts have begun by an


underwriter on behalf of Alkermes in connection with an offering of the
Registrable Securities and ending when such offering is completed or abandoned
or (ii) within one hundred twenty (120) days of the delivery by the Company to
Alkermes of the supplemented or amended prospectus or notice that no such
supplemented or amended prospectus is required with respect to a prior Material
Event. The period of time during which the Company is obligated to maintain the
effectiveness of a registration statement under Section 7.1(b) above shall be
extended by the number of days of any such discontinuance.

7.5  Obligation of the Company to Indemnify. The Company agrees to indemnify
     --------------------------------------
and hold harmless Alkermes or any Person who participates as an underwriter in
the offering or sale of such Registrable Securities, each officer and director
of each underwriter, and each other Person, if any, who "controls" Alkermes or
any such underwriter within the meaning of the Securities Act against any
losses, claims, damages, liabilities and expenses, joint or several, to which
such Person may be subject under the Securities Act or otherwise insofar as such
losses, claims, damages, liabilities (or actions or proceedings in respect
thereof) or expenses arise out of or are based upon (i) any untrue statement or
alleged untrue statement of any material fact contained in any registration
statement under which such Registrable Securities were registered under the
Securities Act, any preliminary prospectus or final prospectus included therein
or filed under Rule 424(b) under the Securities Act, or any amendment or
supplement thereto, or any document incorporated by reference therein, or (ii)
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
the Company will reimburse each such Person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or proceeding; provided, however, that the
                                                   --------  -------
Company will not be liable in any such case to the extent that any such loss,
claim, damage, liability (or action or proceeding in respect thereof) or expense
arises out of or is based upon (i) an untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement,
any such preliminary prospectus or final prospectus, amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by Alkermes or any such underwriter or any Person who "controls"
Alkermes or underwriter for use in the preparation thereof, or (ii) any breach
by Alkermes of the covenant set forth in Section 7.4 above. Such indemnity will
remain in full force and effect regardless of any investigation made by, or on
behalf of, Alkermes or any such underwriter and will survive the transfer of
such Registrable Securities Alkermes.

7.6  Obligation of Alkermes to Indemnify.  Alkermes agrees to indemnify and
     -----------------------------------
hold harmless the Company, each director and each officer of the Company, and
each controlling person within the meaning of the Securities Act of any of the
foregoing who will sign such registration statement, against any losses, claims,
damages, liabilities and expenses, joint or several, to which such Person may be
subject under the Securities Act or otherwise insofar as such losses, claims,
damages, liabilities (or actions or proceedings in respect thereof) or expenses
arise out of, or are based upon, (i) any untrue statement or alleged untrue
statement of any material fact contained in any registration statement under
which such Registrable Securities were registered under the Securities Act, any
preliminary prospectus or final prospectus included


therein or filed under Rule 424(b) under the Securities Act, or any amendment or
supplement thereto, or any document incorporated by reference therein, (ii) any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, (iii)
any breach by Alkermes of the covenant set forth in 7.4 above or (iv) any
failure by Alkermes to deliver a prospectus as required under the Securities Act
or any state securities laws. Alkermes will reimburse each such Person for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided, however, that Alkermes will be liable in any such case
            --------  -------
only to the extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, any such preliminary prospectus or final
prospectus, amendment or supplement, in reliance upon and in conformity with
written information specifically furnished to the Company by Alkermes or any
Person who "controls" Alkermes for use in the preparation thereof.  Such
indemnity will remain in full force and effect regardless of any investigation
made by or on behalf of the Company and will survive the transfer of such
Registrable Securities Alkermes.

7.7  Notice and Defense of Claims.  Promptly after receipt of notice of any
     ----------------------------
claim, liability or expense arising out of the registration or sale of the
Registrable Securities for which a Party seeks indemnification hereunder, such
Party shall give written notice thereof to the indemnifying Party, but such
notification shall not be a condition to indemnification hereunder except to the
extent of actual prejudice to the indemnifying Party. The notice shall state the
information then available regarding the amount and nature of such claim,
liability or expense. If within thirty (30) days after receiving such notice the
indemnifying Party gives written notice to the indemnified Party stating that it
intends to defend against such claim, liability or expense at its own cost and
expense, then defense of such matter, including selection of counsel (subject to
the consent of the indemnified Party which consent shall not be unreasonably
withheld), shall be by the indemnifying Party and the indemnified Party shall
make no payment on such claim, liability or expense as long as the indemnifying
Party is conducting a good faith and diligent defense. The indemnifying Party
shall not be liable to indemnify any person for any settlement of any such
action effected without the written consent of the indemnifying party, which
consent shall not be unreasonably withheld. Notwithstanding the foregoing, the
indemnified Party shall, at all times, have the right to fully participate in
such defense at its own expense directly or through counsel; provided, however,
                                                             --------  -------
if the named parties to the action or proceeding include both the indemnifying
Party and the indemnified Party and representation of both parties by the same
counsel would be inappropriate under applicable standards of professional
conduct, the expense of separate counsel for the indemnified Party shall be paid
by the indemnifying Party. If no such notice of intent to dispute and defend is
given by the indemnifying Party, or if such diligent, good faith defense is not
being or ceases to be conducted, the indemnified Party shall, at the expense of
the indemnifying Party, undertake the defense of such claim, liability or
expense with counsel selected by the indemnified Party, and shall have the right
to compromise or settle the same exercising reasonable business judgment. The
indemnified Party shall make available all information and assistance that the
indemnifying Party may reasonably request and shall cooperate with the
indemnifying Party in such defense.


7.8  Contribution. If the indemnification provided for in this Section 7 is held
     ------------
by a court of competent jurisdiction to be unavailable to an indemnified Party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying Party, in lieu of indemnifying such indemnified
Party hereunder, shall contribute to the amount paid or payable by such
indemnified Party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying Party, on the one hand, and of the indemnified Party, on the other,
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying Party and of the
indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying Party or by the indemnified Party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

7.9  Other Securities Laws.  Indemnification and contribution similar to that
     ---------------------
specified in Sections 7.5, 7.7 and 7.8 (with appropriate modifications) will be
given by the Company and Alkermes with respect to any required registration or
other qualification of such Registrable Securities under any federal or state
law or regulation of any governmental authority other than the Securities Act.

7.10 Covenant to Register Warrant Shares.  The Company will use its best
     -----------------------------------
efforts to effect the registration of the Warrant Shares issuable upon exercise
of the Warrants in blocks of not less than 500,000 shares. The Company will
prepare and file with the SEC within forty five (45) days after the date of
exercise of each of the Warrants, and use best efforts to cause to become
effective as soon as possible thereafter, a registration statement on Form S-3
(or any other appropriate form) under the Securities Act. The Company will
prepare and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection therewith, as may
be necessary to keep such registration statement effective until the earlier of
such time as all of the Warrant Shares have been disposed of in accordance with
the intended method of disposition set forth in such registration statement or
until such time as Alkermes may dispose of the Warrant Shares pursuant to Rule
144(k) under the Securities Act. The Company will use its best efforts to list
all of Warrant Shares covered by such registration statement on the Nasdaq
National Market.

8.   Indemnification.  The Company shall indemnify Alkermes for losses and
     ---------------
expenses resulting from any breach of a covenant or of a representation or
warranty under this Agreement on the date of the Closing or in the event the
second or third sentence in Section 3.8 hereof ever prove to be or have been
                            -----------
untrue.


9.   Miscellaneous.
     -------------

9.1  Amendments.  Any term of this Agreement may be amended and the observance
     ----------
of any obligation hereunder may be waived (either generally or in a particular
instance and either retroactively or prospectively) only with the written
consent of the Company and Alkermes. No failure of any Party to exercise and no
delay in exercising any right, power or remedy in connection with this Agreement
will operate as a waiver thereof, nor will any single or partial exercise of any
right preclude any other or further exercise of such right or the exercise of
any other right.

9.2  Notice.  All notices required or permitted to be given under this
     ------
Agreement shall be governed by the terms of Section 16 of the Sublicense
                                            ----------
Agreement.

9.3  Counterparts.  This Agreement may be executed and delivered (including by
     ------------
facsimile transmission) in one or more counterparts, and by the different
parties hereto in separate counterparts, each of which when executed and
delivered shall be deemed to be an original but all of which taken together
shall constitute one and the same agreement.

9.4  No Waiver.  No failure or delay on the part of Alkermes in exercising
     ---------
any right, power, or privilege hereunder and no course of dealing between the
Company and Alkermes shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power, or privilege hereunder preclude any other
or further exercise thereof or the exercise of any right, power, or privilege.
The rights and remedies herein expressly provided are cumulative and not
exclusive of any rights or remedies that Alkermes would otherwise have.

9.5  Courts of Law. The state and federal courts situated in the Philadelphia
     -------------
County, Commonwealth of Pennsylvania, United States of America, shall have sole
jurisdiction and venue to resolve all disputes arising hereunder between the
Parties and initiated by the Company. The state and federal courts situated in
King County, State of Washington, United States of America, shall have sole
jurisdiction and venue to resolve all disputes arising hereunder between the
Parties and initiated by Alkermes. The Parties irrevocably submit to such
jurisdiction and venue, waive any claim to an inconvenient forum posed by such
venue, and agree that process may be served in any manner permitted by such
court before which a dispute is pending.

9.6  Benefit of Agreement.  Neither Party shall assign any of its rights or
     --------------------
obligations hereunder except: (i) as incident to the merger, consolidation,
reorganization or acquisition of stock or assets affecting substantially all of
the assets or voting control of the assigning Party; (ii) to an Affiliate of the
assigning Party if the assigning Party remains liable and responsible for the
performance and observance of all of the Affiliates' duties and obligations
hereunder; or (iii) with the prior written consent of the other Party. This
Agreement shall be binding upon the successors and permitted assigns of the
Parties, and the name of a Party appearing herein shall be deemed to include the
names of such Party's successor's and permitted


assigns to the extent necessary to carry out the intent of this Agreement. Any
assignment not in accordance with this Section 9.6 shall be void.

9.7  Severability.  If any provision of this Agreement is held invalid under
     ------------
any Applicable Laws, such invalidity shall not affect any other provision of
this Agreement that can be given an effect without the invalid provision, and,
to this end, the provisions hereof are severable.

9.8  Entire Agreement; Governing Law.  This Agreement, and the Sublicense
     -------------------------------
Agreement and the other documents delivered at the Closings constitute the full
and entire understanding and agreement between the parties with respect to the
subject matter hereof and supersede all prior agreements with respect to the
subject matter hereof. This Agreement shall be governed by and construed under
the laws of the State of Washington.
