     5. Other Events

     On January 7, 2000, Ribozyme Pharmaceuticals, Inc. ("Company"), entered
into a joint venture with Elan Corporation, plc and various of its affiliates
(collectively, "Elan") to develop and commercialize the Company's ribozyme
Herzyme(TM) against Human Epidermal Growth Factor Receptor Type 2 ("HER-2") for
treatment of breast and other cancers using Elan's proprietary MEDIPAD(R) Drug
Delivery system.  This joint venture was accomplished through the formation of
Medizyme Pharmaceuticals Ltd.(TM), a Bermuda limited liability company
("Medizyme"), which is owned initially 80.1% by the Company and 19.9% by Elan.

     The Company, Elan and Medizyme entered into the following agreements
related to their joint venture:  (1) License Agreements; (2) Warrants for shares
of the Company's common stock; (3) Convertible Promissory Note; (4) Securities
Purchase Agreement; (5) Subscription, Joint Development and Operating Agreement;
(6) Funding Agreement; and (7) Registration Rights Agreements.  Under the terms
of these agreements, the Company licensed Herzyme to Medizyme, along with
certain other of its intellectual property related to ribozymes directed against
HER-2, and contributed $12.015 million in initial funding to Medizyme in
exchange for 80.1% of Medizyme's capital stock.  The funds used by the Company
to provide this initial funding were received from the Company's sale to Elan of
12,015 shares of its newly authorized Series A convertible exchangeable
preferred stock ($12.015 million in liquidation amount).  Elan has the right to
exchange the Series A preferred stock for 30.1% of the capital stock of Medizyme
owned by the Company or convert it into up to approximately 1,435,000 shares of
the Company's common stock in the future.

     Under the terms of the Convertible Promissory Note, Elan has created a
credit facility available on a draw-down basis for the Company to use to borrow
up to $12.015 million if desired to fund the Company's portion of Medizyme
operating costs over a 2.5 year period. Elan may convert this note and accrued
interest thereon into up to 12,015 shares of the Company's Series B convertible
exchangeable preferred stock in the future.

     The Series B preferred stock shall be entitled to receive mandatory
dividends for six years equal to 12.0% per year of the Original Issue Price of
$1,000.00 per share payable by issuing additional shares of Series B preferred
stock.  The Series B preferred stock and accrued dividends thereon may be
converted at any time into shares of the Company's common stock in an amount
determined by dividing (x) the sum of the Original Issue Price of such share of
Series B preferred stock and all accrued and unpaid dividends thereon by (y) the
Series B Conversion Price, which is a price equal to 150% of the average closing
price of the common stock for the 60 trading days prior to the date of written
notice of the purchase request to the Company.

                                      -2-
<PAGE>

     As part of the transaction, Elan purchased 641,026 shares of the Company's
common stock for a purchase price of $5.0 million and committed to purchase
additional shares of common stock at a premium of up to 30% of the then Market
Price (as defined in the Securities Purchase Agreement and subject to adjustment
as provided therein) for a purchase price of $5.0 million in 15 months. In
addition, Elan received two warrants to purchase shares of the Company's common
stock: (i) a warrant to purchase 200,000 shares at an exercise price of $15.00
per share, and (ii) a warrant to purchase 300,000 shares at an exercise price of
$20.00 per share.

     On January 7, 2000, the Company filed with the Delaware Secretary of State
a Certificate of Designations, Preferences and Rights of Series A Preferred
Stock and Series B Preferred Stock as provided by the Securities Purchase
Agreement.

     On January 31, 2000, the Company entered into a ribozyme manufacturing
agreement with Avecia Limited, acting through its LifeScience Molecules business
("Avecia").  Pursuant to the agreement, the Company transferred proprietary
manufacturing processes and intellectual property to Avecia.  Avecia is expected
to produce certain products for the Company, including Angiozyme(TM), Anti-HCV
ribozyme or other ribozyme products agreed to by the parties.

thereunder shall be made as provided in the Note, upon at least 10 days' written
notice from the Company to EIS, which notices shall set forth a closing date; on
each such closing date, (x) EIS shall fund the amount requested, as provided
herein, and (y) the Company shall cause to be delivered to EIS a certificate or
certificates in respect thereof and a confirmation that the conditions described
in clause (iii) above have been satisfied and the Company shall furnish such

          The Company presently has outstanding a class of preferred stock
captioned Series L Preferred Stock (the "Series L Preferred Stock").  At such
                                         ------------------------
time, if any, during the term of the Note that the Series L Preferred Stock has
been redeemed, converted or otherwise paid in full (and EIS is otherwise
satisfied that the holder(s) thereof do not have any right of seniority over the
Series B Preferred Stock, as contemplated to be issued hereunder), then, in such
event, upon at least 10 business days' written request of the Company, the Note
shall be exchanged for shares of Series B Preferred Stock, as follows.  In such
event, the Note shall be marked canceled and returned to the Company,
simultaneously with the delivery of shares of Series B Preferred Stock to EIS by
the Company; the initial number of shares shall be equal to aggregate amount
funded under the Note and accrued and unpaid interest thereon, divided by
$1,000.  Thereafter, additional shares of Preferred Stock (having up to a
maximum aggregate Original Issue Price, including those previously issued, of
$12.015 million) shall be issued, at the request of the Company, as follows:

               (i)    Each purchase and sale of shares shall be made at such
     time that Newco's board of directors shall have determined that funding is
     required under the JDOA, in accordance with and as permitted by the terms
     thereof, and Newco shall have provided written notice thereof to EIS and to
     the Company; the proceeds of the Series B Preferred Stock shall be used
     solely to satisfy the Company's obligation to provide such funding;

               (ii)   The price per share shall be U.S.$1,000.00, and shares
     shall be issued only in 250-share or greater increments;

               (iii)  A condition to each such purchase shall be (A) that such
     purchase shall occur during the Development Period (as  such term is
     defined in the JDOA) and (B) that there is no material breach or default by
     the Company hereunder or under the JDOA or the Funding Agreement and the
     representations herein shall be true and correct in all material respects
     as of the date made and as of the proposed funding date (updated as to SEC
     Filings and similar matters) and (c) all appropriate and applicable
     regulatory approvals shall have been obtained; and

               (iv)   Purchases and sales of shares of Series B Preferred Stock
     shall be made upon at least 10 days' written notice from the Company to
     EIS, which notices shall set forth a closing date; on each such closing
     date, (x) EIS shall fund the amount required to purchase such shares, as
     provided herein, and (y) the Company shall cause to be delivered to EIS a
     certificate or certificates in respect thereof and a confirmation that the
     conditions described in clause (iii) above have been satisfied and the
     Company shall furnish such documents and instruments that EIS shall
     reasonably request, including updates of the documents referred to in
     clauses 1(d)(ii)(I) and 1(d)(iii) above as well as a certification that the
     representations in Section 2 hereof are, as of such date, true and correct
     in all material respects.

          (f)  Exemption from Registration.  The Securities and any underlying
               ---------------------------
shares of Common Stock will be issued under an exemption or exemptions from
registration under the Securities Act of 1933, as amended (the "Securities

Company hereby represents and warrants to EIS, as of each Closing Date, as
follows:

               ------------
validly existing under the laws of the state of Delaware and has all requisite
corporate power and authority to own and lease its properties, to carry on its
business as presently conducted and as proposed to be conducted and to
consummate the transactions contemplated hereby. The Company is duly qualified
as a foreign corporation and in good standing to do business in each
jurisdiction in which the nature of the business conducted or the property owned
by it requires such qualification, except where the failure to be so qualified
would not, individually or in the aggregate, have a material adverse effect on
the business, assets, liabilities (contingent or otherwise), operations,
condition (financial or otherwise), or prospects of the Company (a "Company
                                                                    -------
Material Adverse Effect").
- -----------------------

          (b)  Capitalization. As of the Closing Date, the Company has reserved
               --------------
a sufficient number of shares of Common Stock (i) for issuance upon conversion
of the Series A Preferred Stock and the Series B Preferred Stock being purchased
hereunder by EIS (including dividends thereon), and (ii) for issuance upon
exercise of the Warrants.  The Securities, when issued against payment therefor
in accordance with this Agreement, will be duly and validly issued, fully paid
and nonassessable, and will not be issued in violation of any preemptive or
similar rights.  The shares of Common Stock underlying the Series A Preferred
Stock, the Series B Preferred Stock and the Warrants (the "Underlying Shares"),
                                                           -----------------
when issued upon conversion or exercise in accordance with the terms thereof,

issued in violation of any preemptive or similar rights.

          (b)  Authorization of Transaction Documents.  The Company has full
               --------------------------------------
corporate power and authority to execute and deliver this Agreement and each of
the other Transaction Documents to which it is a party, and to perform its
obligations hereunder and thereunder.  The execution, delivery and performance
by the Company of this Agreement and each of the other Transaction Documents to
which it is a party, including the issuance and sale of the Securities, have
been duly authorized by all requisite corporate action by the Company and, when
executed and delivered by the Company, this Agreement and each of the other
Transaction Documents to which it is a party will be the valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms.

          (c)  No Violation.  The execution, delivery and performance by the
               ------------
Company of this Agreement and each other Transaction Document to which it is a
party, including the issuance and sale of the Securities, and compliance with
the provisions hereof and thereof by the Company, does not conflict with or
constitute or result in a breach of or default under (or an event which with
notice or passage of time or both would constitute a default) or give rise to
any right of termination, cancellation or acceleration under (i) the Certificate
of Incorporation, as

                                       6
<PAGE>

amended, or by-laws, of the Company, (ii) applicable law, statute, rule or
regulation, or any ruling, writ, injunction, order, judgment or decree of any
court, arbitrator, administrative agency or other governmental body applicable

or any subsequent interim quarterly report, except where such breach, default,
termination, cancellation or acceleration would not, individually or in the
aggregate, have a Company Material Adverse Effect

          (e)  Approvals.  Except as set forth on Schedule 2(e), no permit,
               ---------                          -------------
authorization, consent, approval, or order of or by, or any notification of or
filing with, any person or entity (governmental or otherwise) is required in
connection with the execution, delivery or performance of this Agreement or the
Transaction Documents, including the issuance and sale of the Securities, by the
Company.

          (f)  SEC Filings.  The Company has timely filed with the Securities
               -----------
and Exchange Commission (the "SEC") all forms, reports, schedules, statements,
                              ---
exhibits and other documents (collectively, the "SEC Filings") required to be
                                                 -----------
filed by the Company on or before the date hereof.  At the time filed, the SEC
Filings, including without limitation, any financial statements, exhibits and
schedules included therein or documents incorporated therein by reference (i)
did not contain any untrue statement of a material fact or omit to state a

not misleading and (ii) complied in all material respects with the applicable
requirements of the Securities Act or the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), as the case may be.

          (i)  Absence of Certain Events.  Since September 30, 1999, except as
               --------------------------
contemplated by the Transaction Documents or as set forth on Schedule 2(i)
                                                             -------------
hereto, (A) the Company has not (i) made, paid or declared any dividend or
distribution to any equity holder (in such capacity) or redeemed any of its
capital stock, (ii) varied its business plan or practices, in any material
respect, from past practices, (iii) entered into any financing, joint venture,
license or similar arrangement that would limit or restrict its ability to
perform its obligations hereunder and under each of the other Transaction
Documents to which it is a party, or (iv) suffered or permitted to be incurred
any liability or obligation or any lien or encumbrance against any of its
properties or assets that would limit or restrict its ability to perform its
obligations hereunder and under each of the other Transaction Documents to which
it is a party, and (B) there has not been any change or development which has
had, or in the Company's reasonable judgement is likely to have, a Company
Material Adverse Effect except as disclosed on Schedule 2 (i) hereto.

          (j)  Disclosure.  The representations and warranties set forth
               ----------
herein and in the other Transaction Documents, when viewed collectively, do not
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements contained herein not misleading in light

          SECTION 3.  Representation and Warranties of EIS.  EIS hereby
                      ------------------------------------
represents and warrants to the Company, as of each Closing Date, as follows:

          (a)  Organization.  EIS is an exempted company duly organized, validly
               ------------
existing and in good standing under the laws of Bermuda and has all requisite
corporate power and authority to own and lease its properties, to carry on its
business as presently conducted and as proposed to be conducted and to
consummate the transactions contemplated hereby.  EIS is duly qualified as a
foreign corporation and in good standing to do business in each jurisdiction in
which the nature of the business conducted or the property owned by it requires
such qualification, except where the failure to be so qualified would not,
individually or in the aggregate, have a material adverse effect on the
business, assets, liabilities (contingent or otherwise), operations, condition
(financial or otherwise), or prospects of EIS (an "EIS Material Adverse
                                                   --------------------
Effect").

               --------------------------------------
power and authority to execute and deliver this Agreement and each of the other

including the purchase and acceptance of the Securities, have been duly

enforceable against it in accordance with their respective terms.

                                       8
<PAGE>

          (c)  No Violation.  The execution, delivery and performance by EIS
               ------------
of this Agreement and each other Transaction Document to which it is a party,
including the purchase and acceptance of the Securities, and compliance with
provisions hereof and thereof by EIS, will not conflict with or constitute or
result in a breach of or default under (or an event which with notice or passage
of time or both would constitute a default) or give rise to any right of
termination, cancellation or acceleration under (i) the by-laws of EIS, (ii)
applicable law, statute, rule or regulation, or any ruling, writ, injunction,
order, judgment or decree of any court, arbitrator, administrative agency or
other governmental body applicable to EIS or any of its properties or assets, or
(iii) any material contract to which EIS is a party, except where such breach,
default, termination, cancellation or acceleration would not, individually or in
the aggregate, have an EIS Material Adverse Effect.

          (d)  Approvals.  Except for consent required under the Mergers and
               ---------
Takeovers (Control) Acts 1978-1996 (Ireland), no material permit, authorization,
consent, approval or order of or by, or any notification of or filing with, any
person or entity (governmental or otherwise) is required in connection with the
execution, delivery or performance of this Agreement or the Transaction
Documents by EIS.

          (e)  Investment Representations.
               --------------------------

                   (i)  EIS is sophisticated in transactions of this type and
     capable of evaluating the merits and risks of the transactions described
     herein and in the other Transaction Documents to which it is a party, and
     has the capacity to protect its own interests. EIS has not been formed
     solely for the purpose of entering into the transactions described herein
     and therein and is acquiring the Securities (and the Underlying Shares) for
     investment for its own account, not as a nominee or agent, and not with the
     view to, or for resale, distribution or fractionalization thereof, in whole
     or in part, and no other person (other than Elan) has a direct or indirect
     interest, beneficial or otherwise in the Securities (or the Underlying
     Shares); provided, however, that EIS shall be permitted to convert or
     exchange such Securities in accordance with their terms.

                  (ii)  EIS has not and does not intend to enter into any
     contract, undertaking, agreement or arrangement with any person or entity
     to sell, transfer or pledge the Securities (or the Underlying Shares).

                  (iii) EIS acknowledges its understanding that the private
     placement and sale of the Securities (and the Underlying Shares) is exempt
     from registration under the Securities Act. In furtherance thereof, EIS
     represents and warrants that it is an "accredited investor" as that term is
     defined in the regulations under the Securities Act, has the financial
     ability to bear the economic risk of its investment, has adequate means for
     providing for its current needs and personal contingencies and has no need
     for liquidity with respect to its investment in the Company.

                  (iv)  EIS agrees that it shall not sell or otherwise
     transfer any of the Securities (or the Underlying Shares) without
     registration under the Securities Act or pursuant to an opinion of counsel
     reasonably satisfactory to the Company that an

                                       9
<PAGE>

     exemption from registration is available, and fully understands and agrees
     that it must bear the total economic risk of its purchase for an indefinite
     period of time because, among other reasons, none of the Securities (or the
     Underlying Shares) have been registered under the Securities Act or under
     the securities laws of any applicable state or other jurisdiction and,
     therefore, cannot be resold, pledged, assigned or otherwise disposed of
     unless subsequently registered under the Securities Act and under the
     applicable securities laws of such states or jurisdictions or an exemption
     from such registration is available. EIS understands that the Company is
     under no obligation to register the Securities (or the Underlying Shares)
     on its behalf with the exception of certain registration rights with
     respect to certain of the Securities (and the Underlying Shares), as
     provided in the Company Registration Rights Agreement. EIS understands the
     lack of liquidity and restrictions on transfer of the Securities (and the
     Underlying Shares) and that this investment is suitable only for a person
     or entity of adequate financial means that has no need for liquidity of
     this investment and that can afford a total loss of its investment.

          (f)  Litigation.  There is no legal, administrative, arbitration or
               ----------
other action or proceeding or governmental investigation pending, or to EIS's
knowledge threatened, against EIS that challenges the validity or performance of
this Agreement or the other Transaction Documents to which EIS is a party.

          (g)  Brokers or Finders.  There have been no investment bankers,
               ------------------
brokers or finders used by EIS in connection with the transactions contemplated
by the Transaction Documents and no persons or entities are entitled to a fee or
compensation in respect thereof.

          SECTION 4.  Covenants of the Parties.
                      ------------------------

          (a)  Certain Covenants.  From and after the Closing Date and until the
               -----------------
earlier to occur of the exercise or expiration of the EIS Exchange Right (as
such term is defined in Section 5(c) hereof), the Company shall not without the
prior written consent of EIS:  (i) sell, transfer, encumber, pledge or otherwise
affect, in any respect, (A) any Newco Preferred Shares owned by the Company,
including, without limitation, those Newco Preferred Shares transferable to EIS
upon exercise by EIS of the EIS Exchange Right, or (B) affect, in any respect,
the Company's ability to permit EIS to exercise the EIS Exchange Right in full,
as provided herein or (ii) enter into any material transaction with a director,
officer or more than 20% beneficial owner of Common Stock on other than an arm's
length basis.

          (b)  Fully-diluted Stock Ownership.  Notwithstanding any other
               -----------------------------
provision of this Agreement, in the event that EIS shall have determined that at
any time it (together with its affiliates, if applicable) holds or has the right
to receive Common Stock (or securities or rights, options or warrants
exercisable, exchangeable or convertible for or into Common Stock) representing
in the aggregate in excess of 9.9% of the Company's outstanding Common Stock on
a fully diluted basis, EIS shall have the right to convert the Series A
Preferred Stock, the Note, the Series B Preferred Stock, and the Warrants into
other junior, non-voting securities of the Company (to be specified by EIS and
reasonably agreed to by the Company and not having superior rights to the rights
attendant to the Common Stock) such that EIS and its affiliates will

                                       10
<PAGE>

not directly or indirectly own more than 9.9% of the Common Stock for a period
of at least two years from the election to convert any of the Series A Preferred
Stock, the Note, Series B Preferred Stock or the Warrants. Each of the Company
and EIS shall use commercially reasonable efforts to effect such transactions
and any required subsequent conversions or adjustments to EIS's securities
position, on a quarterly basis, within 15 business days of the end of each of
Elan's fiscal quarters.

          (c)  Use of Proceeds.  The Company shall use the proceeds of (i) the
               ---------------
issuance and sale of the Series A Preferred Stock solely to fund its initial
capital contribution to and funding of Newco as described in the JDOA, and (ii)
the issuance and sale of the Note and the Series B Preferred Stock solely to
fund development amounts in connection with the business of Newco, as described
in the Funding Agreement; and, in each case, for no other purpose.

          (d)  Confidentiality; Non-Disclosure.
               -------------------------------

                  (i)  Subject to clauses (ii) and (iii) below, from and after
     the date hereof, neither the Company nor EIS (nor their respective
     affiliates) shall disclose to any person or entity this Agreement or the
     other Transaction Documents or the contents thereof or the parties thereto,
     except that such parties may make such disclosure (x) to their directors,
     officers, employees and advisors, so long as they shall have advised such
     persons of the obligation of confidentiality herein and for whose breach or
     default the disclosing party shall be responsible, or (y) as required by
     applicable law, rule, regulation or judicial or administrative process,
     provided that the disclosing party uses reasonable efforts to obtain an
     order or ruling protecting the confidentiality of confidential information
     of the other party contained herein or therein. The parties shall be
     entitled to seek injunctive or other equitable relief in respect of any
     breach or threatened breach of the foregoing covenant without the
     requirement of posting a bond or other collateral.

                  (ii) Prior to issuing any press release or public disclosure
     in respect of this Agreement or the transactions contemplated hereby, the
     party proposing such issuance, shall obtain the consent of the other party
     to the contents thereof, which consent shall not be unreasonably withheld
     or delayed; it being understood that if such second party shall not have
     responded to such consent request within two business days, such consent
     shall be deemed given.

          (e)  Further Assurances.  From and after the date hereof, each of the
               ------------------
parties hereto agree to do or cause to be done such further acts and things and
deliver or cause to be delivered to each other such additional assignments,
agreements, powers and instruments, as each may reasonably require or deem
advisable to carry into effect the purposes of this Agreement and the other
Transaction Documents.

          SECTION 5.  Certain Rights of EIS.  (a)  Preemptive Right.  Until
                      ---------------------        ----------------
the fourth anniversary of the Initial Closing Date, EIS shall have the right
(but not the obligation) to participate in any equity, warrant, or convertible
or exchangeable for equity financing consummated by the Company, in order for
EIS to maintain its pro rata interest in the Company, based on the number of
shares of Common Stock owned by EIS and its affiliates, assuring the conversion
or exercise of all Securities and the actual number of shares of Common Stock

                                       11
<PAGE>

outstanding on the date such financing is consummated; provided, that such right
shall not apply to any public offering under the Securities Act, offering under
an option plan, or asset or company acquisition paid for, in whole or in part,
in shares of Common Stock. Such right shall be exercised by EIS within 10 days
of receipt of notice of such financing from the Company, which notice shall be
provided by the Company at least 15 days prior to such financing.  Such
participation by EIS shall be on the same terms and conditions offered to any
other potential investor in such offering.

          (b)  Company Board of Directors. For so long as (i) EIS and/or its
               --------------------------
affiliates or subsidiaries collectively own Securities that represent ownership
of at least 10% of the Common Stock (or Securities convertible, exchangeable or
exercisable for or into the Common Stock) on a fully diluted basis (assuming the
exercise, conversion or exchange by EIS and its affiliates but no other Common
Stock equivalents), or (ii) until the date that is five years after the date
hereof, EIS shall be entitled to nominate one director (the "EIS Director") for
                                                             ------------
election to the Company's Board.  In connection with the foregoing, the Company
will take all necessary and/or appropriate steps to effect such appointment,
including the inclusion of the designated EIS Director on the recommended slate
of directors presented at any regular or special meeting of the stockholders of
the Company at which directors of the Company are to be elected.  Prior to such
election, the designated EIS Director shall be entitled to be an observer at the
meetings of the Company's board of directors.

          (c)  Conversion and Exchange Rights; Etc.  (i)  The Certificate of
               -----------------------------------
Designations sets forth certain rights of the holders of shares of Series A
Preferred Stock to convert such shares of preferred stock into newly issued
shares of Common Stock, or to exchange such shares of Series A Preferred Stock,
subject to the provisions in Section 5 of the Certificate of Designations, for
certain shares of Newco Stock (the "EIS Exchange Right"), both on the terms and
                                    ------------------
conditions set forth therein.

               (ii)  In the event that all or any portion of the issued and
outstanding shares of Series A Preferred Stock are converted into shares of
Common Stock on or prior to the last day permitted to exercise the EIS Exchange
Right, as permitted by the Certificate of Designations, as a result of a merger,
consolidation or similar transaction involving the Company (each, a "Merger
                                                                     ------
Conversion"), then, in such event, the EIS Exchange Right shall not be
- ----------
terminated, as otherwise provided in the Certificate of Designations, but
rather, EIS and the holders of the Series A Preferred Stock shall retain the EIS
Exchange Right until the Exchange Right Termination Date (as defined in the
Certificate of Designations); provided, that the consideration payable to the
Company to exercise the EIS Exchange Right shall be the shares of Common Stock
issued to the holders of the Series A Preferred Stock in connection with a
Merger Conversion rather than the shares of Series A Preferred Stock as
originally provided for in the Certificate of Designations.

          SECTION 6.  [intentionally omitted]

          SECTION 7.  Survival and Indemnification.  (a) Survival.  The
                      -----------------------------      --------
representations and warranties of the Company and EIS contained herein and the
other Transaction Documents shall survive for a period of 24 months from and
after the date hereof.

                                       12
<PAGE>

          (b)  Indemnification.  In addition to all rights and remedies
               ---------------
available to the parties hereto at law or in equity, the Company (in such
capacity, "Indemnifying Party") shall indemnify EIS, its stockholders, officers,
           ------------------
directors and assigns, their affiliates, and its affiliates' stockholders,
officers, directors, employees, agents, representatives, successors and assigns
(collectively, the "Indemnified Person"), and save and hold each Indemnified
                    ------------------
Person harmless from and against and pay on behalf of or reimburse each such
Indemnified Person, as and when incurred, for any and all loss, liability,
demand, claim, action, cause of action, cost, damage, deficiency, tax, penalty,
fine or expense, whether or not arising out of any claims by or on behalf of
such Indemnified Person or any third party, including interest, penalties,
reasonable attorneys' fees and expenses and all amounts paid in investigation,
defense or settlement of any of the foregoing (collectively, "Losses"), that any
                                                              ------
such Indemnified Person may suffer, sustain incur or become subject to, as a
result of, in connection with, relating or incidental to or by virtue of:

               (i)   any misrepresentation or breach of warranty on the part of
     the Indemnifying Party in the case of the Company under Section 2 of this
     Agreement or in the case of EIS under Section 3 of this Agreement or, in
     each case, under any of the other Transaction Documents; or

               (ii)  any nonfulfillment, default or breach of any covenant or
 agreement on the part of the Indemnifying Party under Section 4 of this
 Agreement or any of the other Transaction Documents.

          (c)  Maximum Recovery.   Notwithstanding anything in this Agreement
               ----------------
to the contrary, in no event shall the Indemnifying Parties be liable, in the
case of the Company, for indemnification under this Section 7 in an amount in
excess of the aggregate of the purchase price paid for the Securities, including
the amounts advanced and not repaid under the Note, or, in the case of EIS, for
indemnification hereunder in an amount in excess the Company's costs and
expenses incurred in connection with the transactions contemplated hereby.  No
Indemnified Person shall assert any such claim unless Losses in respect thereof
incurred by any Indemnified Person, when aggregated with all previous Losses
hereunder, equal or exceed U.S.$50,000, but at such time that an Indemnified
Person is entitled to assert a claim, such claim shall include all Losses
covered by this Section 7.

          (d)  Exception.  Notwithstanding the foregoing, upon judicial
               ---------
determination that is final and no longer appealable, that the act or omission
giving rise to the indemnification set forth above resulted primarily out of or
was based primarily upon the Indemnified Person's negligence (unless such
Indemnified Person's negligence was based upon the Indemnified Person's reliance
in good faith upon any of the representations, warranties, covenants or promises
made by the Indemnifying Party herein) the Indemnifying Party shall not be
responsible for any Losses sought to be indemnified in connection therewith, and
the Indemnifying Party shall be entitled to recover from the Indemnified Person
all amounts previously paid in full or partial satisfaction of such indemnity,
together with all costs and expenses (including reasonable attorneys fees) of
the Indemnifying Party reasonably incurred in connection with the Indemnified
Persons claim for indemnity, together with interest at the rate per annum
publicly announced by

                                       13
<PAGE>

Morgan Guaranty Trust Company as its prime rate from the time of payment of such
amounts to the Indemnified Person until repayment to the Indemnifying Party.

          (e)  Investigation.  All indemnification rights hereunder shall
               -------------
survive the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby, to the extent provided in Section 7(g) below,
irrespective of any investigation, inquiry or examination made for or on behalf
of, or any knowledge of the Indemnified Person or the acceptance of any
certificate or opinion.

          (f)  Contribution.  If the indemnity provided for in this Section 7
               ------------
shall be, in whole or in part, unavailable to any Indemnified Person, due to
Section 7(b) being declared unenforceable by a court of competent jurisdiction
based upon reasons of public policy, so that Section 7(b) shall be insufficient
to hold each such Indemnified Person harmless from Losses which would otherwise
be indemnified hereunder, then the Indemnifying Party and the Indemnified Person
shall each contribute to the amount paid or payable for such Loss in such
proportion as is appropriate to reflect not only the relative benefits received
by the Indemnifying Party on the one hand and the Indemnified Person on the
other, but also the relative fault of the Indemnifying Party and be in addition
to any liability that the Indemnifying Party may otherwise have.  The indemnity,
contribution and expense reimbursement obligations that the Indemnifying Party
has under this Section 7 shall survive the expiration of the Transaction
Documents.  The parties hereto further agree that the indemnification and
reimbursement commitments set forth in this Agreement shall apply whether or not
the Indemnified Person is a formal party to any such lawsuit, claims or other
proceedings.

          (g)  Limitation.  No claim shall be brought by an Indemnified Person
               ----------
in respect of any misrepresentation or breach of warranty under this Agreement
after 24 months from the date hereof; and any claim for nonfulfillment, default
or breach of any covenant or any misrepresentation shall be brought within one
year of the date of that such Indemnified Person became aware or should have
become aware of the nonfulfillment, default or breach.  Except as set forth in
the previous sentence and in Section 7(c) above, this Section 7 is not intended
to limit the rights or remedies otherwise available to any party hereto with
respect to this Agreement or the Transaction Documents.

          SECTION 8.  Notices.  All notices, demands and requests of any kind to
                      -------

     Date, including but not limited to the Development License and Supply
     Agreement dated [ * ], and the Manufacturing Agreement dated [ * ] among
     [ * ]

2.2  Elan hereby grants to Newco for a period of [ * ] from the Effective Date a
     nonexclusive license (including the limited right to grant sublicenses
     under Clause 2.6 below) (the "Elan Research License") to the Elan
     Intellectual Property solely to use the System for research and to perform

     to any contractual obligations that Elan has as of the Effective Date,
     including but not limited to the Development License and Supply Agreement
     dated [ * ] and the Manufacturing Agreement dated [ * ]. Newco shall
     provide to
<PAGE>

     the R&D Committee periodic reports not less frequently than quarterly with
     respect to the progress of the research and clinical investigations set

     Elan to Newco, or if Elan in its reasonable good faith judgement after
     consultation with RPI determines that the continuous subcutaneous
     administration of [ * ] using the System is not commercially viable, then
     Elan may terminate the Elan Research License upon thirty (30) days written
     notice to Newco.

     The Parties acknowledge that the provisions relating to the
     commercialization of the continuous subcutaneous administration of [ * ]
     using the System are set forth in Clause 7.2 of the JDOA.

2.3  [ * ] shall be responsible for payments related to the financial provisions
     and obligations of any third party agreement with respect to the Elan
     Intellectual Property to which it is a party on the Effective Date
     (including amendments thereto) (the "Elan Effective Date Agreements"),
     including without limitation, any royalty or other compensation obligations
     triggered thereunder on the Effective Date, or triggered thereunder after
     the Effective Date. Elan hereby confirms that no obligations are in effect
     on the date hereof between Elan and an unaffiliated third party relating to
     the System for use in the Field.

     For the avoidance of doubt, royalties, milestones or other payments which
     arise from the process of the commercialization or exploitation of products
     under the Elan Effective Date Agreements (for example, a milestone payment
     payable upon successful completion of Phase II clinical trials, the filing
     of an NDA application, obtaining NDA approval, or first commercial sale)
     shall be payments for which Elan will be responsible under this Clause 2.3.

2.4  To the extent royalty or other compensation obligations that are payable to
     third parties with respect to the Elan Intellectual Property would be
     triggered after the Effective Date, under any third party agreement entered

     Agreements"), by a proposed use of such Elan Intellectual Property in
     connection with the Project, Elan will inform Newco of such royalty or
     compensation obligations.  If Newco agrees to utilize such Elan
     Intellectual Property in connection with the Project, Newco will be
     responsible for the payment of such royalty or other compensation
     obligations relating thereto.

     For the avoidance of doubt, royalties, milestones or other payments which
     arise from the process of the commercialization or exploitation of products
     under the Elan Post-Effective Date Agreements (for example, a milestone
     payment payable upon successful completion of Phase II clinical trials, the
     filing of an NDA application, obtaining NDA approval, or first commercial
     sale) shall be payments for which Newco will be responsible under this
     Clause 2.4.

     shall have the right outside the Field and subject to the non-competition
     provisions of Clause 4 to exploit and grant licenses and sublicenses of the
     Elan Intellectual Property.

     For the avoidance of doubt, Newco shall have no right to use the Elan
     Intellectual Property outside the Field.

     Research License relating to the Elan Intellectual Property without the

     Elan Research License relating to the Elan Intellectual Property without

     Elan may be withheld in Elan's sole discretion in the case of a proposed
     sublicense of such rights to a Technological Competitor of Elan.

2.7  Any agreement between Newco and any permitted third party for the
     development or exploitation of the Elan Intellectual Property shall require
     such third party to maintain the confidentiality of all information
     concerning the Elan Intellectual Property.

     Insofar as the obligations owed by Newco to Elan are concerned, Newco shall
     remain responsible for all acts and omissions of any permitted sub-
     licensee, including RPI, as if they were acts and omissions by Newco.

          nor in any way affect, Affiliates and subsidiaries (present or future)
          within the division of Elan, plc carrying on business as Elan
          Pharmaceuticals which incorporates, inter alia, EPIL (to the extent
          that EPIL is the owner of patents, know-how or other intellectual

          of Elan, plc carrying on business as Elan Pharmaceuticals), Athena
          Neurosciences, Inc., Elan Pharmaceuticals, Inc., Elan Diagnostics,
          Carnrick Laboratories, and Elan Europe Limited.

4.3. If after the Effective Date Elan acquires know-how or patent rights from a
     third party relating to the System, or if Elan acquires or merges with a
     third party entity that owns or has license rights to know-how or patent
     rights relating to the System, then Elan shall offer to license such know-
     how and patent rights to Newco (subject to existing contractual
     obligations) solely for Newco to research, develop and otherwise engage in
     the commercialization of the Product solely for use in the Field on such
     terms as would be offered to an independent third party negotiating in good
     faith on an arms-length basis.

4.4. If Newco determines that Newco should not acquire such license as is
     referred to in Clause 4.3, then Elan shall be free to fully exploit such
     know-how and patent rights, with the Elan Intellectual Property licensed to
     Newco, whether inside or outside the Field and to grant to third parties
     licenses and sublicenses with respect thereto.

5.   FINANCIAL PROVISIONS

5.1  License Fee:
     ------------
<PAGE>

     In consideration of the license granted by Elan to Newco of the Elan Patent
     Rights under Clause 2, Newco shall pay to Elan a non-refundable license fee
     of [ * ] in cash, the receipt of which is hereby acknowledged by Elan (the
     "License Fee"). The License Fee shall not be subject to future performance
     obligations of Elan to Newco or RPI and shall not be applicable against
     future services provided by Elan to Newco or RPI. The license fee terms as
     set out in this Agreement are independent and distinct from the other terms
     of this Agreement.

5.2  Royalties:
     ----------

     The intent of the Parties is to provide for equivalent economic benefit to
     each of RPI and Elan, except in respect of the License Fee. Accordingly,
     the Management Committee shall decide by unanimous consent on the royalties
     which shall be payable by Newco to RPI and Elan on Net Sales. When
     determining such royalties, the Management Committee shall consider the
     royalty obligations of RPI under the Existing RPI License Agreements,
     provided that any royalties payable by Newco to RPI and Elan hereunder
     shall be distributed in equal amount to each of RPI and Elan. RPI
     represents and warrants to Newco and Elan that RPI's royalty obligations
     under the Existing RPI License Agreements do not exceed an aggregate of
     [ * ] percent of Net Sales.

5.3  Any license fees, royalties or other payments due under this Agreement to
     Elan shall be  apportioned in accordance with a formula agreed between
     Elan, plc and EPIL.

5.4  Payment of royalties pursuant to Clause 5.2 shall be made quarterly in
     arrears during each Financial Year within 30 days after the expiry of the
     calendar quarter.  The method of payment shall be by wire transfer to an
     account specified by Elan.  Each payment made to Elan shall be accompanied
     by a true accounting of all Products sold by Newco's permitted
     sublicensees, if any, during such quarter.

     Such accounting shall show, on a country-by-country and Product-by-Product
     basis, Net Sales (and the calculation thereof) and each calculation of
     royalties with respect thereto, including the calculation of all
     adjustments and currency conversions.

5.5  Newco shall maintain and keep clear, detailed, complete, accurate and
     separate records for a period of 3 years:

     5.5.1  to enable any royalties on Net Sales that shall have accrued
            hereunder to be determined; and

     5.5.2  to enable any deductions made in the Net Sales calculation to be
            determined.

5.6  All payments due hereunder shall be made in United States Dollars. Payments
     due on Net Sales of any Product for each calendar quarter made in a
     currency other than United States Dollars shall first be calculated in the
     foreign currency and then
<PAGE>

     converted to United States Dollars on the basis of the exchange rate in
     effect on the last working day for such quarter for the purchase of United
     States Dollars with such foreign currency quoted in the Wall Street Journal
     (or comparable publication if not quoted in the Wall Street Journal) with
     respect to the currency of the country of origin of such payment,
     determined by averaging the rates so quoted on each business day of such
     quarter.

5.7  If, at any time, legal restrictions in the Territory prevent the prompt
     payment when due of royalties or any portion thereof, the Parties shall
     meet to discuss suitable and reasonable alternative methods of paying Elan
     the amount of such royalties.  In the event that Newco is prevented from
     making any payment under this Agreement by virtue of the statutes, laws,
     codes or government regulations of the country from which the payment is to
     be made, then such payments may be paid by depositing them in the currency
     in which they accrue to Elan's account in a bank acceptable to Elan in the
     country the currency of which is involved or as otherwise agreed by the
     Parties.

5.8  Elan and Newco agree to co-operate in all respects necessary to take
     advantage of any double taxation agreements or similar agreements as may,
     from time to time, be available.

5.9  Any taxes payable by Elan on any payment made to Elan pursuant to this
     Agreement shall be for the account of Elan.  If so required by applicable
     law, any payment made pursuant to this Agreement shall be made by Newco
     after deduction of the appropriate withholding tax, in which event the
     Parties shall co-operate to obtain the appropriate tax clearance as soon as
     is practicable.  On receipt of such clearance, Newco shall forthwith
     arrange payment to Elan of the amount so withheld.

6.   RIGHT OF INSPECTION AND AUDIT

6.1  Once during each Financial Year, or more often not to exceed quarterly as
     reasonably requested by Elan, Newco shall permit Elan or its duly
     authorized representatives, upon reasonable notice and at any reasonable
     time during normal business hours, to have access to inspect and audit the
     accounts and records of Newco and any other book, record, voucher, receipt
     or invoice relating to the calculation of the royalty payments on Net Sales
     submitted to Elan.

     Any such inspection of Newco's records shall be at the expense of Elan,
     except that if any such inspection reveals a deficiency in the amount of
     the royalty actually paid to Elan hereunder in any Financial Year quarter
     of 5% or more of the amount of any royalty actually due to Elan hereunder,
     then the expense of such inspection shall be borne solely by Newco.  Any
     amount of deficiency shall be paid promptly to Elan by Newco.
<PAGE>

     If such inspection reveals a surplus in the amount of royalties actually
     paid to Elan by Newco, Elan shall reimburse Newco the surplus within 15
     days after determination.

6.2  In the event of any unresolved dispute regarding any alleged deficiency or
     overpayment of royalty payments hereunder, the matter will be referred to
     an independent firm of chartered accountants chosen by agreement of RPI and
     Elan for a resolution of such dispute.  Any decision by the said firm of
     chartered accountants shall be binding on the Parties.

            United States of America, Bermuda or Ireland, is filed, and is not
            discharged within 60 days, or a Party applies for or consents to the
            appointment of a receiver, administrator, examiner or similar
            officer of it or of all or a material part of its assets, rights or
            revenues or the assets and/or the business of a Party are for any
            reason seized, confiscated or condemned.

8.4  Elan shall be entitled to terminate this Agreement in the event of a Change

             Territory or in such particular country or countries in the
             Territory (as the case may be) prior to the expiration or
             termination of this Agreement as set forth herein shall be paid in
             full within 60 days after the expiration or termination of this
             Agreement for the Territory or for such particular country or
             countries in the Territory (as the case may be);

     8.5.2  any provisions that expressly survive termination or expiration of
            this Agreement, including without limitation this Clause 8, shall
            remain in full force and effect;

     8.5.3  all representations, warranties and indemnities shall insofar as are
            appropriate remain in full force and effect;

            rights of Newco pursuant to Clause 11 of the JDOA with respect to
            patent prosecution and maintenance; and the rights of Newco to the
            Elan Intellectual Property pursuant to Clause 7.2 of the JDOA with
            respect to the development and commercialization of [ * ] using the
            System) shall cease for the Territory or for such particular country
            or countries in the Territory (as the case may be) and shall revert
            to or be transferred to Elan, and Newco shall not thereafter use in
            the Territory or in such particular country or countries in the
            Territory (as the case may be) any rights covered by this Agreement;
<PAGE>

     8.5.6  subject to Clause 8.5.7 and to such license, if any, granted by
            Newco to Elan pursuant to the provisions of Clause 12 of the JDOA
            (entitled "Cross Licensing/Exploitation of Products Outside the
            Field"), all rights to Newco Intellectual Property shall be
            transferred to and jointly owned by RPI and Elan and may be
            exploited by both Elan and RPI separately, provided that Elan and
            RPI will cooperate reasonably in the prosecution and maintenance of
            patents claiming such technology and rights and provided further
            that nothing hereunder shall grant, or be construed to grant, the
            right (a) to Elan to make, have made, import, use, offer for sale or
            sell the Target Ribozyme, and (b) to RPI to make, have made, import,
            use, offer for sale or sell the System;

            In the event of a dispute arising pursuant to this Clause 8.5.6,
            Elan and RPI agree to negotiate in good faith on the course of
            action to be taken with respect to determining their respective
            entitlements pursuant to this Clause; and

     8.5.7  the rights of permitted third party sub-licensees in and to the Elan
            Intellectual Property shall survive the termination of the license
            and sublicense agreements granting said intellectual property rights
            to Newco; and Newco, Elan and RPI shall in good faith agree upon the
            form most advantageous to Elan and RPI in which the rights of Newco
            under any such licenses and sublicenses are to be held (which form
            may include continuation of Newco solely as the holder of such
            licenses or assignment of such rights to a third party or parties,
            including an assignment to both Elan and RPI).

            Any sublicense agreement between Newco and such permitted
            sublicensee shall permit an assignment of rights by Newco and shall
            contain appropriate confidentiality provisions.

9.   CONFIDENTIAL INFORMATION

9.1  The Parties agree that it will be necessary, from time to time, to disclose
     to each other confidential and proprietary information, including without
     limitation, inventions, works of authorship, trade secrets, specifications,
     designs, data, know-how and other proprietary information relating to the
     Field, the Products, processes, services and business of the disclosing
     Party.

     The foregoing shall be referred to collectively as "Confidential
     Information".

9.2  Any Confidential Information disclosed by one Party to another Party shall
     be used by the receiving Party exclusively for the purposes of fulfilling
     the receiving Party's obligations under this Agreement and the JDOA and for
     no other purpose.

9.3  Each Party shall disclose Confidential Information of the other Party only
     to those employees, representatives and agents requiring knowledge thereof
     in connection with
<PAGE>

     fulfilling the Party's obligations under this Agreement. Each Party further
     agrees to inform all such employees, representatives and agents of the
     terms and provisions of this Agreement and their duties hereunder and to
     obtain their agreement hereto as a condition of receiving Confidential
     Information. Each Party shall exercise the same standard of care as it
     would itself exercise in relation to its own confidential information (but
     in no event less than a reasonable standard of care) to protect and
     preserve the proprietary and confidential nature of the Confidential
     Information disclosed to it by the other Party. Each Party shall, upon
     request of the other Party, return all documents and any copies thereof
     containing Confidential Information belonging to, or disclosed by, such
     other Party.

9.4  Any breach of this Clause 9 by any person informed by one of the Parties is
     considered a breach by the Party itself.

9.5  Confidential Information shall not be deemed to include:

     9.5.1  information that is in the public domain;

     9.5.2  information which is made public through no breach of this
            Agreement;

     9.5.3  information which is independently developed by a Party as evidenced
            by such Party's records;

     9.5.4  information that becomes available to a Party on a non-confidential
            basis, whether directly or indirectly, from a source other than a
            Party, which source did not acquire this information on a
            confidential basis; or

     9.5.5  information which the receiving Party is required to disclose
            pursuant to:

            (i)   a valid order of a court or other governmental body; or

            (ii)  any other requirement of law;

            provided that if the receiving Party becomes legally required to
            disclose any Confidential Information, the receiving Party shall
            give the disclosing Party prompt notice of such fact so that the
            disclosing Party may obtain a protective order or other appropriate
            remedy concerning any such disclosure. The receiving Party shall
            fully co-operate with the disclosing Party in connection with the
            disclosing Party's efforts to obtain any such order or other remedy.
            If any such order or other remedy does not fully preclude
            disclosure, the receiving Party shall make such disclosure only to
            the extent that such disclosure is legally required.

9.6  The provisions relating to confidentiality in this Clause 9 shall remain in
     effect during the term of this Agreement, and for a period of 7 years
     following the expiration or
<PAGE>

      earlier termination of this Agreement.

9.7   The Parties agree that the obligations of this Clause 9 are necessary and
      reasonable in order to protect the Parties' respective businesses, and
      each Party agrees that monetary damages would be inadequate to compensate
      a Party for any breach by the other Party of its covenants and agreements
      set forth herein.

      Accordingly, the Parties agree that any such violation or threatened
      violation shall cause irreparable injury to a Party and that, in addition
      to any other remedies that may be available, in law and equity or
      otherwise, each Party shall be entitled to obtain injunctive relief
      against the threatened breach of the provisions of this Clause 9, or a
      continuation of any such breach by the other Party, specific performance
      and other equitable relief to redress such breach together with its
      damages and reasonable counsel fees and expenses to enforce its rights
      hereunder, without the necessity of proving actual or express damages.

9.8   For the avoidance of doubt, all Confidential Information of Newco received
      by Elan hereunder shall not be disclosed by Elan to Affiliates and/or
      subsidiaries of Elan, plc within the division of Elan, plc carrying on
      business as Elan Pharmaceuticals (excluding disclosure of such
      Confidential Information to senior personnel of Elan who are bound by
      confidentiality provisions but such persons shall have no right to further
      disclose such confidential information) which division incorporates, inter
      alia, EPIL (to the extent that it is the owner of patents, know-how or
      other intellectual property or technology invented and/or developed within
      the division of Elan, plc carrying on business as Elan Pharmaceuticals),
      Athena Neurosciences, Inc., Elan Pharmaceuticals, Inc., Elan Diagnostics,
      Carnrick Laboratories, and Elan Europe Limited.

10.   GOVERNING LAW AND JURISDICTION; ARBITRATION

10.1. This Agreement shall be governed by and construed in accordance with the
      laws of the State of New York, without giving effect to the provisions
      thereof relating to the conflict of laws.

10.2  The Parties will attempt in good faith to resolve any dispute arising out
      of or relating to this Agreement promptly by negotiation between
      executives of the Parties. In the event that such negotiations do not
      result in a mutually acceptable resolution, the Parties agree to consider
      other dispute resolution mechanisms including mediation.

      In the event that the Parties fail to agree on a mutually acceptable
      dispute resolution mechanism, any such dispute shall be finally settled by
      arbitration pursuant to Clause 10.3.

10.3  Any dispute under this Agreement which is not settled by mutual consent
      under
<PAGE>

     Clause 10.2 and which relates to (i) the interpretation or enforcement of
     any provision of this Agreement, (ii) the interpretation or application of
     law, or (iii) the ownership of any intellectual property shall be finally
     settled by binding arbitration, conducted in accordance with the Commercial
     Arbitration Rules of the American Arbitration Association ("AAA") by one
     arbitrator appointed in accordance with said rules. Such arbitrator shall
     be an independent expert in pharmaceutical product development and
     marketing (including clinical development and regulatory affairs) and shall
     be reasonably satisfactory to each of the Parties; provided, that if the
     Parties are unable to agree upon the identity of such arbitrator within 15
     days of demand by either Party, then either Party shall have the right to
     petition the AAA to appoint an arbitrator.

     The arbitration shall be held in New York, New York.

     The arbitrator shall determine what discovery will be permitted, consistent
     with the goal of limiting the cost and time which the Parties must expend
     for discovery; provided the arbitrator shall permit such discovery as they
     deem necessary to permit an equitable resolution of the dispute.

     Any written evidence originally in a language other than English shall be
     submitted in English translation accompanied by the original or a true copy
     thereof.

     The costs of the arbitration, including administrative and arbitrators'
     fees, shall be shared equally by the Parties and each Party shall bear its
     own costs and attorneys' and witness' fees incurred in connection with the
     arbitration.

     In rendering judgment, the arbitrators may not provide for punitive or
     similar exemplary damages.

     A disputed performance or suspended performances pending the resolution of
     the arbitration must be completed within 30 days following the final
     decision of the arbitrators or such other reasonable period as the
     arbitrators determine in a written opinion.

     Any arbitration under this Agreement shall be completed within one year
     from the filing of notice of a request for such arbitration.

     The arbitration proceedings and the decision shall not be made public
     without the joint consent of the Parties and each Party shall maintain the
     confidentiality of such proceedings and decision unless otherwise permitted
     by the other Party.

     The Parties agree that the decision shall be the sole, exclusive and
     binding remedy between them regarding any and all disputes, controversies,
     claims and counterclaims presented to the arbitrators.  Application may be
     made to any court having jurisdiction over the Party (or its assets)
     against whom the decision is rendered for a
<PAGE>

     judicial recognition of the decision and an order of enforcement.


11.  IMPOSSIBILITY OF PERFORMANCE - FORCE MAJEURE

     Neither Elan nor Newco shall be liable for delay in the performance of any
     of its obligations hereunder if such delay results from causes beyond its
     reasonable control, including, without limitation, acts of God, fires,
     strikes, acts of war, intervention of a government authority, but any such
     delay or failure shall be remedied by such Party as soon as practicable.


12.  ASSIGNMENT


     This Agreement may not be assigned by either Party without the prior
     written consent of the other, save that either Party may assign this
     Agreement to its Affiliates or subsidiaries without such prior written
     consent and that Elan may assign this Agreement to any off-balance sheet
     special purpose entity established by Elan or EIS or their respective
     Affiliates without such prior written consent; provided that such
     assignment does not have any adverse tax consequences on the other Party.

THIS WARRANT CERTIFICATE AND THE SECURITIES REPRESENTED BY THIS WARRANT
CERTIFICATE AND THE SHARES OF STOCK ISSUABLE UPON EXERCISE HEREOF HAVE BEEN
ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR ANY SECURITIES LAWS OF A STATE OR OTHER JURISDICTION AND
MAY NOT UNDER ANY CIRCUMSTANCES BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF
(OTHER THAN TO AN AFFILIATE OR AS OTHERWISE PERMITTED BY THIS WARRANT

SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR

                        RIBOZYME PHARMACEUTICALS, INC.

                          WARRANT TO PURCHASE SHARES
                                OF COMMON STOCK

          THIS CERTIFIES THAT, for value received, Elan International Services,
Ltd., a Bermuda exempted limited liability company, or its permitted transferees
and successors as provided herein (each, a "Holder"), is entitled to subscribe
                                            ------
for and purchase up to 300,000 shares, as adjusted pursuant to Section 4 (the
"Shares"), of the fully paid and nonassessable common stock, par value $.01 (the
- -------
"Common Stock"), of Ribozyme Pharmaceuticals, Inc., a Delaware corporation (the
 ------------
"Company"), at the price of U.S.$20.00 per share (such price, and such other
 -------
prices that shall result from time to time, from the adjustments specified in
Section 4, the "Warrant Price"), subject to the provisions and upon the terms
                -------------
and conditions hereinafter set forth.

          1. Term.  Subject to the limitations set forth in Sections 3 and 4,
             ----
the purchase right represented by this Warrant is exercisable, in whole or in
part, at any time, and from time to time, from and after the date hereof and
until 5:00 p.m. Eastern Standard Time, January 7/th/, 2007.  To the extent not
exercised at 5:00 p.m. Eastern Standard Time on January 7/th/, 2007, this
Warrant shall terminate and expire, and thereafter it shall be of no force or
effect.
<PAGE>

          2. Method of Exercise; Payment; Issuance of New Warrant. (a) The
             -----------------------------------------------------
purchase right represented by this Warrant may be exercised by the Holder, in
whole or in part and from time to time, by the surrender of this Warrant (with
the notice of exercise form attached hereto as Annex A duly executed) at the
                                               -------
principal office of the Company and by the payment to the Company of an amount,
in cash or other immediately available funds, equal to the then-applicable
Warrant Price per Share multiplied by the number of Shares then being purchased.

          (b)  The persons or entities in whose name(s) any certificate(s)
representing Shares shall be issuable upon exercise of this Warrant shall be
deemed to have become the holder(s) of record of, and shall be treated for all
purposes as the record holder(s) of, the Shares represented thereby (and such
Shares shall be deemed to have been issued) immediately prior to the close of
business on the date or dates upon which this Warrant is properly exercised and
full payment for the Shares acquired pursuant to such exercise is made.  Upon
any exercise of the rights represented by this Warrant, certificates for the
Shares purchased shall be delivered to the holder hereof as soon as possible and
in any event within 30 days of receipt of such notice and payment, and unless
this Warrant has been fully exercised or expired, a new Warrant representing the
portion of Shares, if any, with respect to which this Warrant shall not then
have been exercised shall also be issued to the holder hereof as soon as
possible and in any event within such 30-day period.

          3. Stock Fully Paid, Reservation of Shares.  All Shares that may be
             ---------------------------------------
issued upon the exercise of this Warrant shall, upon issuance, be duly and
validly authorized and issued, fully paid and nonassessable, and will be free
from all transfer taxes, liens and charges with respect to the issue thereof and
assuming payment of the Warrant Price for all Shares so purchased, legally and
validly owned by the Holder.  During the period within which this Warrant may be
exercised, the Company will at all times have authorized, and reserved for the
purpose of the issue upon the exercise of the purchase rights evidenced by this
Warrant, a sufficient number of shares of its Common Stock to provide for the
exercise of the rights represented by this Warrant.

          4.  Adjustment of Warrant Price and Number of Shares.  The number and
              ------------------------------------------------
kind of securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to the adjustment from time to time upon the occurrence
of certain events, as follows:

          (a) Reclassification, Etc.  In case of (i) any reclassification,
              -----------------------
reorganization, change or conversion of securities of the class issuable upon
exercise of this Warrant (other than a change in par value, or from par value to
no par value) or other shares or securities of the Company, or (ii) any
consolidation of  the Company with or into another entity (other than a merger
or consolidation with another entity in which the Company is the acquiring and
the surviving entity and that does not result in any reclassification or change
of outstanding securities issuable upon exercise of this Warrant), or (iii) any
sale of all or substantially all the assets of the Company, then, in any event,
(x) the Company, or such successor or purchasing entity, as the case may be,
shall duly execute and deliver to the holder of this Warrant a new Warrant or a
supplement hereto (in form and substance reasonably satisfactory to the holder
of this Warrant),

                                       2
<PAGE>

and (y) the Holder shall have the right to receive, at a total purchase price
not to exceed that payable upon the exercise of the unexercised portion of this
Warrant, and in lieu of the shares of Common Stock theretofore issuable upon the
exercise of this Warrant, the kind and amount of shares of stock and other
securities, receivable upon such reclassification, reorganization, change or
conversion by a holder of the number of shares of Common Stock then purchasable
under this Warrant. Such new Warrant shall provide for adjustments that shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Section 4. The provisions of this Section 4(a) shall similarly attach to
successive reclassifications, reorganizations, changes, and conversions.

          (b)  Subdivision or Combination of Shares.  If the Company at any
               ------------------------------------
time during which this Warrant remains outstanding and unexpired shall subdivide
or combine its Common Stock, (i) in the case of a subdivision, the Warrant Price
shall be proportionately and appropriately decreased and the number of Shares
purchasable hereunder shall be proportionately and appropriately increased, and
(ii) in the case of a combination, the Warrant Price shall be proportionately
and appropriately increased and the number of Shares purchasable hereunder shall
be proportionately and appropriately decreased.

          (c)  No Impairment.  The Company will not, by amendment of its
               -------------
Articles of Incorporation or bylaws or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the Holder against impairment.

          (d)  Notice of Adjustments.  Whenever the Warrant Price or the number
               ---------------------
of Shares purchasable hereunder shall be adjusted pursuant to this Section 4,
the Company shall prepare a certificate setting forth, in reasonable detail, the
event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated.  Such certificate shall be signed by its
chief financial officer and shall be delivered to the Holder.

          (e)  Fractional Shares.  No fractional Shares will be issued in
               -----------------
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor based on the fair market value of
the Common Stock on the date of exercise as reasonably determined in good faith
by the Company's Board of Directors.

          (f)  Cumulative Adjustments.  No adjustment in the Warrant Price shall
               ----------------------
be required under this Section 4 until cumulative adjustments result in a
concomitant change of 1% or more of the Warrant Price or in the number of shares
of Common Stock purchasable upon exercise of this Warrant as in effect prior to
the last such adjustment; provided, however, that any adjustment that by reason
of this Section 4 are not required to be made shall be carried

                                       3
<PAGE>

forward and taken into account in any subsequent adjustment. All calculations
under this Section 4 shall be made to the nearest cent or to the nearest one-
hundredth of a share, as the case may be.

          5.  Compliance with Securities Act; Disposition of Warrant or Shares
              ----------------------------------------------------------------
of Common Stock.  (a)  The Holder, by acceptance hereof, agrees that this
- ---------------
Warrant and the Shares to be issued upon exercise hereof are being acquired for
investment and that such holder will not offer, sell or otherwise dispose of
this Warrant or any Shares to be issued upon exercise hereof except under
circumstances which will not result in a violation of applicable securities
laws.  Upon exercise of this Warrant, unless the Shares being acquired are
registered under the Securities Act of 1933, as amended (the "Act"), or an
                                                              ---
exemption from the registration requirements of such Act is available, the
Holder shall confirm in writing, by executing an instrument in form reasonably
satisfactory to the Company, that the Shares so purchased are being acquired for
investment and not with a view toward distribution or resale.  This Warrant and
all Shares issued upon exercise of this Warrant (unless registered under the
Act) shall be stamped or imprinted with a legend in substantially the following
form:

THIS WARRANT CERTIFICATE AND THE SECURITIES REPRESENTED BY THIS WARRANT
CERTIFICATE AND THE SHARES OF STOCK ISSUABLE UPON EXERCISE HEREOF HAVE BEEN
ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED, OR ANY SECURITIES LAWS OF A STATE OR OTHER JURISDICTION AND
MAY NOT UNDER ANY CIRCUMSTANCES BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF
(OTHER THAN TO AN AFFILIATE OR AS OTHERWISE PERMITTED BY THIS WARRANT
CERTIFICATE PURSUANT TO WHICH THEY WERE ISSUED) EXCEPT PURSUANT TO (i) AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND ANY APPLICABLE
STATE SECURITIES OR BLUE SKYLAWS, OR (ii) TO THE EXTENT APPLICABLE, RULE 144
UNDER THE SECURITIES ACT (OR ANY SIMILAR RULE UNDER THE SECURITIES ACT RELATING
TO THE DISPOSITION OF SECURITIES) TOGETHER WITH AN OPINION OF COUNSEL
SATISFACTORY TO THE COMPANY THAT REGISTRATION IS NOT REQUIRED UNDER SUCH ACT OR
APPLICABLE STATE SECURITIES LAWS.

          (b)(i) This Warrant may be transferred or assigned, in whole or in
part, (a) by EIS to its affiliates and subsidiaries, as well as any special
purpose financing or similar vehicle established by EIS or its affiliates.
Other than as set forth above, this Warrant may not be transferred or assigned
by either party without the prior written consent of the other.  Subject to the
foregoing, this Warrant and all of the provisions hereof shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns; provided, however that the transferor and the Company
shall continue to be liable and obligated for their respective obligations
hereunder after any such assignment.

                                       4
<PAGE>

          (ii)  With respect to any offer, sale or other disposition of this
Warrant or any Shares acquired pursuant to the exercise of this Warrant prior to
registration of such Shares, the Holder shall give written notice to the Company
prior thereto, describing briefly the manner thereof, together with a written
opinion of such holders counsel, if requested by the Company, to the effect that
such offer, sale or other disposition may be effected without registration or
qualification (under the Act as then in effect or any federal or state law then
in effect) of this Warrant or such Shares and indicating whether or not under
the Act certificates for this Warrant or such Shares to be sold or otherwise
disposed of require any restrictive legend as to applicable restrictions on
transferability in order to ensure compliance with the Act.  Promptly upon
receiving such written notice and reasonably satisfactory opinion, if so
requested, the Company, as promptly as practicable, shall notify such Holder
that such Holder may sell or otherwise dispose of this Warrant or such Shares,
all in accordance with the terms of the notice delivered to the Company.  Each
certificate representing this Warrant or the Shares thus transferred shall bear
a legend as to the applicable restrictions on transferability in order to insure
compliance with the Securities Act, unless in the aforesaid opinion of counsel
for the Holder such legend is not required in order to insure compliance with
the Securities Act.  The Company may issue stop transfer instructions to its
transfer agent in connection with such restrictions.

          (iii) The shares of Common Stock underlying this Warrant are entitled
to the benefit of certain registration rights as set forth in a Registration
Rights Agreement dated as of the date hereof between the Company and the initial
Holder named herein.

          6.  Rights as Shareholders.  No Holder, as such, shall be entitled to
              ----------------------
vote or receive dividends or be deemed the holder of Shares or any other

exercise of this Warrant (other than a change in par value, or from par value to

consolidation of  the Company with or into another entity (other than a merger
or consolidation with another entity in which the Company is the acquiring and
the surviving entity and that does not result in any reclassification or change
of outstanding securities issuable upon exercise of this Warrant), or (iii) any
sale of all or substantially all the assets of the Company, then, in any such
event, (x) the Company, or such successor or purchasing entity, as the case may
be, shall duly execute and deliver to the holder of this Warrant a new Warrant
or a supplement hereto (in form and substance reasonably satisfactory to the
holder of this Warrant), and (y) the Holder shall have the right to receive, at

<PAGE>

Warrant, the kind and amount of shares of stock and other securities, receivable
upon such reclassification, reorganization, change or conversion by a holder of
the number of shares of Common Stock then purchasable under this Warrant. Such
new Warrant shall provide for adjustments that shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 4. The
provisions of this Section 4(a) shall similarly attach to successive
reclassifications, reorganizations, changes, and conversions.

          (b)   Subdivision or Combination of Shares.  If the Company at any
                ------------------------------------
time during which this Warrant remains outstanding and unexpired shall subdivide
or combine its Common Stock, (i) in the case of a subdivision, the Warrant Price
shall be proportionately and appropriately decreased and the number of Shares
purchasable hereunder shall be proportionately and appropriately increased, and
(ii) in the case of a combination, the Warrant Price shall be proportionately
and appropriately increased and the number of Shares purchasable hereunder shall
be proportionately and appropriately decreased.

          (c)   No Impairment.  The Company will not, by amendment of its
                -------------
Articles of Incorporation or bylaws or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the Holder against impairment.

          (d)   Notice of Adjustments.  Whenever the Warrant Price or the number
                ---------------------
of Shares purchasable hereunder shall be adjusted pursuant to this Section 4,
the Company shall prepare a certificate setting forth, in reasonable detail, the
event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated.  Such certificate shall be signed by its
chief financial officer and shall be delivered to the Holder.

          (e)   Fractional Shares.  No fractional Shares will be issued in
                -----------------
connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor based on the fair market value of
the Common Stock on the date of exercise as reasonably determined in good faith
by the Company's Board of Directors.

          (f)   Cumulative Adjustments. No adjustment in the Warrant Price shall
                ----------------------
be required under this Section 4 until cumulative adjustments result in a
concomitant change of 1% or more of the Warrant Price or in the number of shares
of Common Stock purchasable upon exercise of this Warrant as in effect prior to
the last such adjustment; provided, however, that any adjustment that by reason
of this Section 4 are not required to be made shall be carried forward and taken
into account in any subsequent adjustment.  All calculations under this Section
4 shall be made to the nearest cent or to the nearest one-hundredth of a share,
as the case may be.

          ----------------

          (i)   From and after the Original Issue Date and until this Note is
repaid in full, the Holder shall have the right from time to time, in its sole
discretion, to convert all or any portion of the outstanding principal amount
and accrued and unpaid interest then-outstanding hereunder, (the "Conversion
                                                                  ----------
Right"), into such number of shares of Series B Preferred Stock that shall be
- -----
obtained by dividing the sum of the outstanding principal amount and all accrued
and unpaid interest by $1,000, subject to adjustment as provided below in this
Section (the "Conversion Price").
              ----------------

          (ii)  The Holder shall be entitled to exercise the Conversion Right
from time to time as to the uncoverted portion of this Note upon at least five
days' prior written notice to the Company, such notice to be in the form
attached hereto as Exhibit B.  Within 10 days of the conversion date specified
                   ---------
in such notice, the Company shall issue appropriate stock certificates to EIS
representing the aggregate number of shares of Series B Preferred Stock due to
EIS as a result of such conversion.

     (b)  Reclassification, Etc.  In case of (i) any reclassification,
          ----------------------
reorganization, change or conversion of securities of the class issuable upon
conversion of the outstanding principal amount and accrued and unpaid interest
then-outstanding hereunder (other than a change in par value, or from par value
to no par value), or (ii) any consolidation of the Company with or into another
entity (other than a merger or consolidation with another entity in which the
Company is the surviving entity and that does not result in any reclassification
or change of the class of securities issuable upon the conversion of the
outstanding principal amount and accrued and unpaid interest then-outstanding
hereunder), or (iii) any sale of all or substantially all the assets of the
Company, then the Company, or such successor or purchasing entity, as the case
may be, shall duly execute and deliver to the Holder a new Note or a supplement
hereto (in form and substance reasonably satisfactory to the Holder of this
Note), so that the Holder shall have the right to receive, in lieu of the shares
of Series B Preferred Stock otherwise issuable upon the conversion of such
outstanding principal amount and accrued and unpaid interest then-outstanding
hereunder, the kind and amount of shares of stock and other securities, money
and

                                       3
<PAGE>

property receivable upon such reclassification, reorganization, change, merger,
consolidation or conversion by a holder of the number of shares of Series B
Preferred Stock then issuable under this Note. Such new Note shall provide for
adjustments that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 4. The provisions of this Section 4(b)
shall similarly attach to successive reclassifications, reorganizations,
changes, mergers, consolidations, transfers or conversions.

     (c) No Impairment.  The Company will not, by amendment of its Certificate
         -------------
of Incorporation or bylaws or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
the provisions of this Section 4 and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of EIS against
impairment.  This provision shall not restrict the Company from otherwise
amending and/or restating its Certificate of Incorporation in accordance with
the laws of the State of Delaware.

     (d) Notice of Adjustments.  Whenever the consideration issuable upon a
         ---------------------
conversion hereunder shall be changed pursuant to this Section 4, the Company
shall prepare a certificate setting forth, in reasonable detail, the event
requiring the change and the kind and amount of shares of stock and other
securities, money and property subsequently issuable upon a conversion hereof.
Such certificate shall be signed by its chief financial officer and shall be
delivered to EIS.

     (e) Fractional Shares; Rounding.  No fractional shares of Series B
         ---------------------------
Preferred Stock will be issued in connection with any exercise hereunder, but in
lieu of such fractional shares the Company shall make a cash payment therefor
based on the applicable Conversion Price.  All calculations under this Section 4
shall be made to the nearest cent or to the nearest one-hundredth of a share, as
the case may be.

     SECTION 5.  EXCHANGE RIGHT.

     In the event that EIS shall exercise the EIS Exchange Right during the
period during which this Note is outstanding, EIS shall, at its option, (i)
cause to be paid to the Company, within 30 days of such exercise, an amount
equal to 30.1% of the aggregate amount (including any accrued and unpaid
interest thereon) of the Development Funding (as such term is defined in the
Funding Agreement) through the date of such exercise provided by each of the
parties to Newco, in accordance with the terms of the Funding Agreement, from
and after the date hereof and until the date of such exercise, and/or (ii)
offset against the amount payable under this Note an amount equal to 30.1% of
the total amount (including any accrued and unpaid interest in respect of any
debt, including the Note thereon) of Development Funding provided by each of the
parties to Newco, in accordance with the terms of the Funding Agreement, from
and after the date hereof and until the date of the exercise of the Exchange
Right, against the principal amount outstanding

                                       4
<PAGE>

hereunder, if any, or (iii) effect a combination of the provisions described in
clauses (i) and (ii) above, if applicable.

     SECTION 6.  USE OF PROCEEDS.

          The Company shall use the proceeds of this Note solely for
developmental funding of Newco; provided, that Newco's shareholders (as provided
for in the JDOA) shall have determined that such developmental funding is
necessary and that the parties thereto are in continuing agreement as to the
Business Plan.  Accordingly, total disbursements hereunder shall not in any
event exceed the amount of Development Funding funded by the Company to Newco
pursuant to the Funding Agreement.

     SECTION 7.  EVENTS OF DEFAULT.

          The occurrence of any of the following events shall constitute an
event of default (an "Event of Default"):

and as the same shall become due and payable;

     (b)  a default in the payment of any accrued and unpaid interest on this

     (c)  a breach by the Company of its obligations under any of the
Transaction Documents, which breach remains uncured 10 days after written notice
thereof by EIS;

     (d)  a distress, execution, sequestration or other process is levied or
enforced upon the Company or sued out against a material part of its property
which is not discharged or challenged within 60 days;

     (e)  the Company is unable to pay its debts in the normal course of
business;

     (f)  the Company ceases wholly or substantially to carry on its business,

trustee or similar officer of the Company or over all or substantially all of
its assets under the law; or

     (h)  any other termination of the JDOA.

<PAGE>

     (a)  In the case of any Event of Default by the Company, the Holder may, in
its sole discretion, demand that the aggregate amount of funds advanced to the
Company under this Note and outstanding hereunder and accrued and unpaid
interest thereon shall, in addition to all other rights and remedies of the
Holder hereunder and under applicable law, be and become immediately due and
payable upon written notice delivered by the Holder to the Company.
Notwithstanding the preceding sentence, the rights of the Holder as set forth in
Sections 4 and 5 hereunder shall survive any such acceleration and payment.  If
the Holder shall accelerate and be paid and thereafter elect to exercise the
Conversion Right, the Holder shall reimburse to the Company an amount in respect
of the shares of Series B Preferred Stock issued under such Conversion Right
equal to the principal amount of this Note attributable thereto as calculated in
accordance with Section 4 above.  If the Holder shall accelerate and be paid and
thereafter elect to exercise the Exchange Right, the Holder shall cause to be
paid to the Company an amount as calculated in accordance with Section 5(i)
above.

     (b)  The Company hereby waives demand and presentment for payment, notice
of nonpayment, protest and notice of protest, diligence, filing suit, and all
other notice and promises to pay the Holder its costs of collection of all
amounts due hereunder, including reasonable attorneys' fees.

     (c)  In the case of any Event of Default under this Note by the Company
this Note shall continue to bear interest after such default at the interest
rate otherwise in effect hereunder plus 3% per annum (but in any event not in
excess of the maximum rate of interest permitted by applicable law).

     SECTION 9.  MISCELLANEOUS.

     (a)  EIS may assign this Note to its affiliates and subsidiaries, as well
as any special purpose financing or similar vehicle established by EIS or its
affiliates.  This Note and all of the provisions hereof shall be binding upon

and permitted assigns; provided, however, that EIS and the Company shall remain
liable for their respective obligations hereunder after any such assignment.

                    authorization, consent or approval of or by, or any
                    notification of or filing with, any Person is required in

                    this Agreement by such Shareholder.

            3.2.5   Investment Representations:  Such Shareholder is
                    --------------------------
                    sophisticated in transactions of this type and capable of
                    evaluating the merits and risks of its investment in Newco.
                    Such Shareholder has not been formed solely for the purpose
                    of making this investment and such Shareholder is acquiring
                    the Common Shares and Preferred Shares for investment for
                    its own account, not as a nominee or agent, and not with the
                    view to, or for resale in connection with, any distribution
                    of any part thereof. Such Shareholder understands that the
                    Shares have not been registered under the Securities Act or
                    applicable state and foreign securities laws by reason of a
                    specific exemption from the registration provisions of the
                    Securities Act and applicable state and foreign securities
                    laws, the availability of which depends upon, among other
                    things, the bona fide nature of the investment intent and
                    the accuracy of such Shareholders' representations as
                    expressed herein. Such Shareholder understands that no
                    public market now exists for any of the Shares and that
                    there is no assurance that a public market will ever exist
                    for such Shares.

4.6. EIS and RPI shall use reasonable efforts to file any documents that require
     filing with the Registrar of Companies in Bermuda within the prescribed
     time limits.

4.7. In the event that EIS exercises the Exchange Right, Newco shall,
     immediately upon such exercise, take all necessary steps to ensure that EIS
     is duly and validly issued and has full legal right, title and interest in
     and to the shares of Preferred Shares covered thereby.  The Parties

     exercises the Exchange Right, RPI shall retain all rights in and to the
     pledged Newco Shares (including without limitation all voting, dividend,
     liquidation and other rights), subject only to this pledge and the terms of
     this Agreement.

     5.1.1     Prior to the exercise of the Exchange Right, the Board shall be
               composed of five Directors.

               RPI shall have the right to nominate four directors of Newco

               Director of Newco ("EIS Director")

                                       16
<PAGE>

               which Director, save as further provided herein, shall only be
               entitled to 15% of the votes of the Board.

               In the event that the Exchange Right is exercised by EIS within
               two years following the Closing Date, the EIS Director shall only
               be entitled to 15% of the votes of the Board until the expiry of
               two years from the Closing Date.

               In the event that the Exchange Right is exercised by EIS at any
               time after two years following the Closing Date or upon the
               expiry of two years following the Closing Date where the Exchange
               Right has been exercised by EIS within two years following the
               Closing Date, each of RPI, and EIS shall cause the Board to be
               reconfigured so that an equal number of Directors are designated
               by EIS and RPI and that each of the Directors has equal voting
               power.

       5.1.2   If EIS removes the EIS Director, or RPI removes any of the RPI
               Directors, EIS or RPI, as the case may be, shall indemnify the
               other Shareholder against any claim by such removed Director
               arising from such removal.

       5.1.3   The Directors shall meet not less than three times in each
               Financial Year and all Board meetings shall be held in Bermuda to
               the extent required pursuant to the laws of Bermuda or to ensure
               the sole residence of Newco in Bermuda.

               least two of the RPI Directors shall be required to constitute a
               quorum and, subject to Clause 18 hereof, the affirmative vote of
               a majority of the Directors present at a meeting at which such a
               quorum is present shall constitute an action of the Directors. In
               the event of any meeting being inquorate, the meeting shall be
               adjourned for a period of seven days. A notice shall be sent to
               the EIS Director and the RPI Directors specifying the date, time
               and place where such adjourned meeting is to be held and
               reconvened.

       5.1.5   On the Closing Date, RPI may appoint one of the RPI Directors to
               be the chairman of Newco. The chairman of Newco shall hold office
               until:

               (i) the first meeting of the Board following the exercise by EIS
                   of the Exchange Right, where the Exchange Right has been
                   exercised by EIS after two years following the Closing Date;
                   or

              (ii) the first meeting of the Board following the expiry of two
                   years following the Closing Date where the Exchange Right
                   has been exercised by EIS within two years following the
                   Closing Date

               (in each case the "Chairman Status Board Meeting")

               After the Chairman Status Board Meeting, each of EIS and RPI,
               beginning with EIS at the Chairman Status Board Meeting, shall
               have the right, exercisable

                                       17
<PAGE>

               alternatively, of nominating one Director to be chairman of Newco
               for a term of one year.

               If the chairman is unable to attend any meeting of the Board held
               prior to the Chairman Status Board Meeting, the RPI Directors
               shall be entitled to appoint another RPI Director to act as
               chairman in his place at the meeting.

               If the chairman of Newco is unable to attend any meeting of the
               Board held after the Chairman Status Board Meeting, the Directors
               shall be entitled to appoint another Director to act as chairman
               of Newco in his place at the meeting.

       5.1.6   In case of an equality of votes at a meeting of the Board, the
               chairman of Newco shall not be entitled to a second or casting
               vote. In the event of continued deadlock, the Board shall resolve
               the deadlock pursuant to the provisions set forth in Clause 19.

               shall be nominated by RPI, and each of whom shall be entitled to
               one vote, whether or not present at any Management Committee
               meeting. Decisions of the Management Committee shall require

               and one RPI nominee on the Management Committee.

               Each of Elan and RPI shall be entitled to remove any of their
               nominees to the Management Committee and appoint a replacement in
               place of any nominees so removed. The number of members of the
               Management Committee may be altered if agreed to by a majority of
               the directors of Newco; provided that, each of Elan and RPI shall
               be entitled to appoint an equal number of members to the
               Management Committee. The Management Committee shall be
               responsible for, inter alia, devising, implementing and reviewing
               strategy for the Project.

     5.2.2     The Management Committee shall appoint a research and development
               committee (the "R&D Committee"), which shall initially be
               comprised of four members, two of whom shall be nominated by Elan
               and two of whom shall be nominated by RPI, and each of whom shall
               have one vote, whether or not present at an R&D Committee meeting
               during which research and development issues are discussed.
               Decisions of the R&D Committee shall require approval of at least
               one Elan nominee on the R&D Committee and one RPI nominee on the
               R&D Committee.

               Each of Elan and RPI shall be entitled to remove any of their
               nominees to the R&D Committee and appoint a replacement in place
               of any nominees so removed. The number of members of the R&D
               Committee may be altered if agreed to by a majority of the
               directors of Newco provided that each of Elan and

                                       18
<PAGE>

               RPI shall be entitled to appoint an equal number of members to
               the R&D Committee.

     5.2.3     The R&D Committee shall be responsible for:

               5.2.3.1   designing that portion of the Business Plan that
                         relates to the Project for consideration by the
                         Management Committee;

               5.2.3.2   establishing a joint Project team consisting of an
                         equal number of team members from Elan and RPI,
                         including one Project leader from each of Elan and RPI;
                         and

               5.2.3.3   implementing such portion of the Business Plan that
                         relates to the Project, as approved by the Management
                         Committee.

     5.2.4     In the event of any dispute amongst the R&D Committee, the R&D
               Committee shall refer such dispute to the Management Committee
               whose decision on the dispute shall be binding on the R&D
               Committee. If the Management Committee cannot resolve the matter
               after 15 days or such other period as may be agreed by the
               Management Committee, the dispute will be referred to the
               President of Elan Pharmaceutical Technologies and the Chief
               Executive Officer of RPI, and thereafter, in the event of
               continued deadlock, pursuant to the deadlock provisions to be set
               forth in Clause 19, involving inter alia, the referral of the
               dispute to an expert, whose decision, however, will ultimately be
               non-binding on the Participants.

                         RESEARCH AND DEVELOPMENT WORK

7.1  Research and development work related to the Products and the Newco
     Intellectual Property shall be conducted in accordance with the research
     and development program developed by the R&D Committee and approved by the
     Management Committee.

7.2  The Parties acknowledge that in addition to the Elan License, Elan granted
     to Newco the Elan Research License pursuant to the Elan License Agreement
     solely to use the System for research and to perform clinical
     investigations to determine the commercial viability of the continuous
     subcutaneous administration of [ * ] using the System. If the Parties
     jointly determine that the continuous subcutaneous administration of [ * ]
     using the System is commercially viable, then the Parties shall in good
     faith negotiate a nonexclusive license to Newco of the Elan Intellectual
     Property and of the RPI Intellectual Property to make, have made, import,
     use, offer for sale and sell such product, subject to then existing
     contractual obligations. Such license agreement shall contain normal
     commercial terms, provided that (i) the research, development and
     commercialization of such product shall be without any cost or obligation
     whatsoever to Elan without Elan's prior written consent which may be
     withheld in Elan's sole discretion, and (ii) [ * ]

     Notwithstanding anything contained in this Clauses 7.2 to the contrary,
     Newco shall not have the license or right to manufacture or have
     manufactured the System with respect to the Product or to manufacture or
     have manufactured [ * ] with respect to the product described in this
     Clause 7.2. The Parties agree that the manufacture of the System and [ * ]
     is subject to Clause 14 below.

7.3  Subject to the provisions of Clause 6.3, Elan and RPI shall undertake at
     their discretion research and development work related to the development
     and commercialization of the Products, at the request of Newco and as
     articulated in the Business Plan, in furtherance of the development and
     commercialization of the Products and cultivation of patent rights and
     know-how related to the Elan Intellectual Property, RPI Intellectual
     Property and Newco Intellectual Property. The cost of such development work
     shall be Elan's and RPI's, as the case may be, fully-burdened actual costs
     in respect thereof, plus [*] of such costs. Research and development work
     that is sub-contracted by Elan or RPI to third party providers shall be
     charged by Elan or RPI to Newco at the amount invoiced by the relevant
     third party provider. Newco shall pay RPI and Elan for any research and
     development work carried out by them on behalf of Newco at the end of each
     month during the Research and Development Program, subject to the proper
     vouching of research and development work and expenses. An invoice shall be
     issued to Newco by RPI or Elan, as applicable, by the 15/th/ day of the
     month following the month in which work was performed.

                                       20

7.4  Elan and RPI shall use reasonable efforts in undertaking any such research
     and development work undertaken for Newco hereunder to conduct such
     research and development work in a professional and timely manner.

7.5  Elan and RPI shall permit Newco or its duly authorized representative on
     reasonable notice and at any reasonable time during normal business hours
     to have access to inspect and audit the accounts and records of Elan or RPI
     and any other book, record, voucher, receipt or invoice relating to the
     calculation or the cost of the Research and Development Program and to the
     accuracy of the reports which accompanied them. Any such inspection of
     Elan's or RPI's records, as the case may be, shall be at the expense of
     Newco, except that if such inspection reveals an overpayment in the amount
     paid to Elan or RPI, as the case may be, for the Research and Development
     Program hereunder in any Financial Year of [ * ] or more of the amount due
     to Elan or RPI, as the case may be, then the expense of such inspection
     shall be borne solely by Elan or RPI, as the case may be, instead of by
     Newco. Any surplus over the sum properly payable by Newco to Elan or RPI,
     as the case may be, shall be paid promptly by Elan or RPI, as the case may
     be, to Newco. If such inspection reveals a deficit in the amount of the sum
     properly payable to Elan or RPI, as the case may be, by Newco, Newco shall
     pay the deficit to Elan or RPI, as the case may be.

                               COMMERCIALIZATION

8.1  Newco shall diligently pursue the research, development, prosecution and
     commercialization of the Products as provided in the Business Plan.

8.2  At such time as Newco notifies Elan in writing that Newco in good faith
     intends to commercialize a Product, Elan shall have a [ * ] the terms of
     any agreement for [ * ], which option shall be exercised within [*] days of
     Elan's receipt of such written notification from Newco (the "Elan/Newco
     Option"); [ * ]. If Elan elects to enter into such negotiations, the
     Parties shall negotiate in good faith the terms of an applicable agreement.

     If, despite good faith negotiations, Elan and Newco do not reach agreement
     within [ * ] from [ * ], then Newco shall be free to enter into
     negotiations and an agreement with a third party (other than a
     Technological Competitor of Elan) upon which the third party would
     commercialize the relevant Product in the Territory, which terms when taken
     as a whole, are not more favourable to the third party than the principal
     terms of the last written proposal offered by Newco to Elan or by Elan to
     Newco, as the case may be. The Parties shall act in good faith and use
     their reasonable commercial judgement when negotiating with such third
     party for the commercialization of the Product in the Territory. For
     purposes of this Clause 8.2, the term Elan shall include Elan and its
     Affiliates.

                         INTELLECTUAL PROPERTY RIGHTS

11.1      Elan, at its expense and sole discretion shall (i) secure the grant of
          any patent applications within the Elan Patents that relate to the
          Field; (ii) file and prosecute patent applications on patentable
          inventions and discoveries within the Elan Improvements that relate to
          the Field; (iii) defend all such applications against third party
          oppositions; and (iv) maintain in force any issued letters patent
          within the Elan Patents that relate to the Field (including

                                       22
<PAGE>

          any letters patent that may issue covering any such Elan Improvements
          that relate to the Field). Elan shall have the right in its sole
          discretion to control such filing, prosecution, defense and
          maintenance provided that Newco and RPI at their request shall be
          provided with copies of all documents relating to such filing,
          prosecution, defense and maintenance in sufficient time to review such
          documents and comment thereon prior to filing.

11.2      RPI, at its expense and sole discretion, shall (i) secure the grant of
          any patent applications within the RPI Patents that relate to the
          Field; (ii) file and prosecute patent applications on patentable
          inventions and discoveries within the RPI Improvements that relate to
          the Field; (iii) defend all such applications against third party
          oppositions; and (iv) maintain in force any issued letters patent
          within the RPI Patents that relate to the Field (including any letters
          patent that may issue covering any such RPI Improvements that relate
          to the Field). RPI shall have the right in its sole discretion to
          control such filing, prosecution, defense and maintenance provided
          that Elan and Newco at their request shall be provided with copies of
          all documents relating to such filing, prosecution, defense and
          maintenance in sufficient time to review such documents and comment
          thereon prior to filing.

11.3      In the event that Elan does not intend to file for patent protection
          on patentable inventions or discoveries within the Elan Intellectual
          Property that relates to the Field in one or more countries in the
          Territory after providing written notice to Newco and RPI, Newco shall
          have the option at Newco's expense, upon the prior written approval of
          Elan which approval shall not be unreasonably withheld, to request
          Elan to file and prosecute such patent application(s) jointly on
          behalf of Newco and RPI. Upon such written request from Newco, Elan
          shall be responsible for preparing and prosecuting and otherwise
          seeking patent protection for such Elan Intellectual Property
          described in this Clause 11.3. Any such Elan Intellectual Property
          shall be owned by Elan but Elan shall grant to Newco a royalty free
          exclusive license to such Elan Intellectual Property in the Field. The
          Parties shall have the right to remove their confidential information
          from any such patent application.

11.4      In the event that RPI does not intend to file for patent protection on
          patentable inventions or discoveries within the RPI Intellectual
          Property that relates to the Field in one or more countries in the
          Territory after providing written notice to Newco and Elan, Newco
          shall have the option at Newco's expense, upon the prior written
          approval of RPI which approval shall not be unreasonably withheld, to
          request RPI to file and prosecute such patent application(s) jointly
          on behalf of Newco and Elan. Upon such written request from Newco, RPI
          shall be responsible for preparing and prosecuting and otherwise
          seeking patent protection for such RPI Intellectual Property described
          in this Clause 11.3. Any such RPI Intellectual Property shall be owned
          by RPI but RPI shall grant a royalty free exclusive license to Newco
          to such RPI Intellectual Property in the Field. The Parties shall have
          the right to remove their confidential information from any such
          patent application.

                                       23
<PAGE>

11.5      Newco at its expense shall have the right but shall not be obligated
          (i) to file and prosecute patent applications on patentable inventions
          and discoveries within the Newco Intellectual Property; (ii) to defend
          all such applications against third party oppositions; and (iii) to
          maintain in force any issued letters patent within the Newco Patents
          (including any patents that issue on patentable inventions and
          discoveries within the Newco Intellectual Property). Newco shall have
          the right to control such filing, prosecution, defense and maintenance
          provided that the other Parties shall be provided with copies of all
          documents relating to such filing, prosecution, defense, and
          maintenance in sufficient time to review such documents and comment
          thereon prior to filing. The Parties shall have the right to remove
          their confidential information from any such patent application.

11.6      In the event that Newco informs both Elan and RPI that it does not
          intend to file an application on the Newco Intellectual Property in or
          outside the Field, Elan shall have the right to file and prosecute
          such patent applications on inventions that Elan invents solely or
          which relate predominantly to the Elan Intellectual Property, and RPI
          shall have the right to file and prosecute such patent applications on
          inventions which RPI invents solely or which relate predominantly to
          the RPI Intellectual Property, and Elan and RPI agree to negotiate in
          good faith on the course of action to be taken with respect to Newco
          inventions that relate to both the Elan and RPI Intellectual Property.
          The Parties shall have the right to remove their confidential
          information from any such patent application.

11.7      The Parties shall promptly inform each other in writing of any actual
          or alleged unauthorized use of any Elan Intellectual Property, the RPI
          Intellectual Property or the Newco Intellectual Property by a third
          party of which it becomes aware and provide the others with any
          available evidence of such unauthorized use.

11.8      At its option, as the case may be, Elan or RPI shall have the first
          option to enforce at its own expense and for its own benefit any
          unauthorized use of its respective Intellectual Property (the Elan
          Intellectual Property or the RPI Intellectual Property as the case may
          be) in the Field. At the enforcing party's request, the other Parties
          shall cooperate with such action. Should Elan or RPI decide not to
          enforce the Elan Intellectual Property or the RPI Intellectual
          Property respectively, against such unauthorized use in the Field,
          within a reasonable period but in any event within twenty (20) days
          after receiving written notice of such actual or alleged unauthorized
          use, Newco may in its discretion initiate such proceedings in its own
          name, at its expense and for its own benefit, and at such Party's
          request, Elan and RPI shall cooperate with such action. Any recovery
          remaining after the deduction by Newco of the reasonable expenses
          (including attorney's fees and expenses) incurred in relation to such
          enforcement proceeding shall belong to Newco. Alternatively, the
          Parties may agree to institute such proceedings in their joint names
          and shall reach agreement as to the proportion in which they shall
          share the proceeds of any such proceedings, and the expense of any
          costs not recovered, or the costs or damages payable to the third
          party. If the infringement of the Elan Patents or the RPI Patents
          affects both the Field as well as other products being developed or
          commercialized by RPI or Elan or its commercial partners outside the
          Field, RPI or Elan shall endeavor to agree as to the manner in which
          the proceedings should be instituted and as to the proportion in which
          they shall share the proceeds of any such proceedings,

                                       24
<PAGE>

          and the expense of any costs not recovered, or the costs or damages
          payable to the third party.

11.9      Newco shall have the first right but not the obligation to bring suit
          or otherwise take action against any unauthorized use of the Newco
          Intellectual Property. If any such alleged use occurs that gives rise
          to a cause of action both inside and outside the Field, Newco, in
          consultation with the other Parties, shall determine the course of
          action to be taken. In the event that Newco takes such action, Newco
          shall do so at its own cost and expense and all damages and monetary
          award recovered in or with respect to such action shall be the
          property of Newco. Newco shall keep Elan and RPI informed of any
          action in a timely manner so as to enable RPI and Elan to provide
          input in any such action and Newco shall reasonably take into
          consideration any such input. At Newco's request, the Parties shall
          cooperate with any such action at Newco's cost and expense.

11.10     In the event that Newco does not bring suit or otherwise take action
          against any unauthorized use of the Newco Intellectual Property (i) if
          only one Party determines to pursue such suit or take such action at
          its own cost and expense, it shall be entitled to all damages and
          monetary award recovered in or with respect to such action and (ii) if
          the other Parties pursue such suit or action outside of Newco, they
          shall negotiate in good faith an appropriate allocation of costs,
          expenses and recovery amounts. At the Party's request, Newco shall
          cooperate with any such action at the Party's cost and expense.

11.11     In the event that a claim or proceeding is brought against Newco by a
          third party alleging that the sale, distribution or use of a Product
          in the Territory constitutes the unauthorized use of the intellectual
          property rights of such Party, Newco shall promptly advise the other
          Parties of such threat or suit.

11.12     Save in respect of claims by Newco against either Party, or by an
          Independent Third Party against Newco, where Elan is in breach of a
          representation or warranty under [ * ] or where RPI is in breach of a
          representation or warranty under [ * ] shall indemnify, defend and
          hold harmless Elan or RPI, as the case may be, against all actions,
          losses, claims, demands, damages, costs and liabilities (including
          reasonable attorneys fees) relating directly or indirectly to all such
          claims or proceedings referred to in [ * ], provided that Elan
          or RPI, as the case may be, shall not acknowledge to the third party
          or to any other person the validity of any claims of such a third
          party, and shall not compromise or settle any claim or proceedings
          relating thereto without the prior written consent to Newco, not to be
          unreasonably withheld or delayed. At its option, Elan or RPI, as the
          case may be, may elect to take over the conduct of such proceedings
          from Newco provided that Newco's indemnification obligations shall
          continue; the costs of defending such claim shall be borne by Elan or
          RPI, as the case may be and such Party shall not compromise or settle
          any such claim or proceeding without the prior written consent of
          Newco, such consent not to be unreasonably withheld or delayed.

          it shall have with an RHA, and shall furnish the other Parties with
          copies of all correspondence relating to the Products. The Parties
          shall collaborate to obtain any required Regulatory Approval of the
          RHA to market the Products.

13.2      Subject to the unanimous determination of the Management Committee
          that one or more regulatory approvals for permission to conduct
          clinical studies and/or for commercialization should be held in the
          name of Newco's commercial partner, such regulatory approvals related
          to the Products and/or the Newco Intellectual Property shall be
          prosecuted and owned by Newco in accordance with the Business Plan.

          All regulatory approvals and submissions relating to the Target
          Ribozyme, including without limitation, the DMF, shall be processed by
          and be the property of RPI and at all times held in RPI's sole name.
          All regulatory approvals and submissions relating to the System,
          including without limitation, the MAF, shall be processed by and be
          the property of Elan and at all times held in Elan's sole name. Each
          of Elan and RPI will authorize Newco to reference such Party's
          respective regulatory approval and submission, as described herein,
          with the FDA and such foreign agency to the extent necessary for
          Newco's regulatory purposes.

13.3      It is hereby acknowledged that there are inherent uncertainties
          involved in the registration of pharmaceutical products with the RHA's
          insofar as obtaining approval is concerned and such uncertainties form
          part of the business risk involved in undertaking the form of
          commercial collaboration as set forth in this Agreement.

                     RIGHT OF FIRST OFFER; TAG ALONG RIGHTS

     General:
     --------

17.1. Until such time as the Common Shares shall be registered pursuant to the
      Exchange Act and be publicly traded in an established securities market,
      no Shareholder shall, directly or indirectly, sell or otherwise transfer
      (each, a "Transfer") any Shares held by it except in as expressly
      permitted by and in accordance with the terms of this Agreement. Newco
      shall not, and shall not permit any transfer agent or registrar for any
      Shares to, transfer upon the books of Newco any Shares from any
      Shareholder to any transferee, in any manner, except in accordance with
      this Agreement, and any purported transfer not in compliance with this
      Agreement shall be void.

      During the Research and Development Term, no Shareholder shall, directly
      or indirectly, sell or otherwise Transfer any of its legal and/or
      beneficial interest in the Shares held by it to any other Person. After
      completion of the Research and Development Term, a

                                       29
<PAGE>

      Shareholder may Transfer Shares provided such Shareholder complies with
      the provisions of Clauses 17.2 and 17.3.

      Notwithstanding anything contained herein to the contrary, at all times,
      EIS and/or RPI shall have the right to Transfer any Shares to their
      Affiliates provided, however, that such assignment does not result in
      adverse tax consequences for any other Parties. EIS shall have the right
      to Transfer any Shares to a special purpose financing or similar entity
      established by Elan or EIS; provided, that such Affiliates or other
      Permitted Transferee to which such legal and/or beneficial interest in the
      Shares have been transferred shall agree to be expressly subject to and
      bound by all the limitations and provisions which are embodied in this
      Agreement.

17.2  No Shareholder shall, except with the prior written consent of the other
      Shareholder, create or permit to subsist any Encumbrance over or in, all
      or any of the Shares held by it (other than by a Transfer of such Shares
      in accordance with the provisions of this Agreement).

17.3  Rights of First Offer:
      ----------------------

      If at any time after the end of the Research and Development Term a
      Shareholder shall desire to Transfer any Shares owned by it (a "Selling
      Shareholder"), in any transaction or series of related transactions other
      than a Transfer to an Affiliate or subsidiary or in the case of EIS to a
      special purpose financing or similar entity established by EIS, then such
      Selling Shareholder shall deliver prior written notice of its desire to
      Transfer (a "Notice of Intention") (i) to Newco and (ii) to the
      Shareholders who are not the Selling Shareholder (and any transferee
      thereof permitted hereunder, if any), as applicable, setting forth such
      Selling Shareholder's desire to make such Transfer, the number of Shares
      proposed to be transferred (the "Offered Shares") and the proposed form of
      transaction (the "Transaction Proposal"), together with any available
      documentation relating thereto, if any, and the price at which such
      Selling Shareholder proposes to Transfer the Offered Shares (the "Offer
      Price"). The "Right of First Offer" provided for in this Clause 17 shall
      be subject to any "Tag Along Right" benefiting a Shareholder which may be
      provided for by Clause 17, subject to the exceptions set forth therein.

      Upon receipt of the Notice of Intention, the Shareholders who are not the
      Selling Shareholder shall have the right to purchase at the Offer Price
      the Offered Shares, exercisable by the delivery of notice to the Selling
      Shareholder (the "Notice of Exercise"), with a copy to Newco, within 10
      business days from the date of receipt of the Notice of Intention. If no
      such Notice of Exercise has been delivered by the Shareholders who are not
      the Selling Shareholder within such 10-business day period, or such Notice
      of Exercise does not relate to all of the Offered Shares covered by the
      Notice of Intention, then the Selling Shareholder shall be entitled to
      Transfer all of the Offered Shares to the intended transferee. In the
      event that all of the Offered Shares are not purchased by the non-selling
      Shareholders, the Selling Shareholder shall sell the available Offered
      Shares within 30 days after the delivery of such Notice of Intention on
      terms no more favorable to a third party than those presented to the non-
      selling Shareholders. If such sale does not

                                       30
<PAGE>

      occur, the Offered Shares shall again be subject to the Right of First
      Refusal set forth in Clause 17.3.

      In the event that any of the Shareholders who are not the Selling
      Shareholder exercises their right to purchase all of the Offered Shares
      (in accordance with this Clause 17), then the Selling Shareholder shall
      sell all of the Offered Shares to such Shareholder(s), in the amounts set
      forth in the Notice of Intention, after not less than 10 business days and
      not more than 25 business days from the date of the delivery of the Notice
      of Exercise. In the event that more than one of the Shareholders who are
      not the Selling Shareholders wish to purchase the Offered Shares, the
      Offered Shares shall be allocated to such Shareholders on the basis of
      their pro rata equity interests in Newco.

      The rights and obligations of each of the Shareholders pursuant to the
      Right of First Offer provided herein shall terminate upon the date that
      the Common Shares are registered under Section 12(b) or 12(g) of the
      Exchange Act.

      At the closing of the purchase of all of the Offered Shares by the
      Shareholders who are not the Selling Shareholder (scheduled in accordance
      with Clause 17), the Selling Shareholder shall deliver certificates
      evidencing the Offered Shares being sold, duly endorsed, or accompanied by
      written instruments of transfer in form reasonably satisfactory to the
      Shareholders who are not the Selling Shareholder, duly executed by the
      Selling Shareholder, free and clear of any adverse claims, against payment
      of the purchase price therefor in cash, and such other customary documents
      as shall be necessary in connection therewith.

17.4  Tag Along Rights:
      -----------------

      Subject to Clause 17.3, a Shareholder (the "Transferring Shareholder")
      shall not Transfer (either directly or indirectly), in any one transaction
      or series of related transactions, to any Person or group of Persons, any
      Shares, unless the terms and conditions of such Transfer shall include an
      offer to the other Shareholders (the "Remaining Shareholders"), to sell
      Shares at the same price and on the same terms and conditions as the
      Transferring Shareholder has agreed to sell its Shares (the "Tag Along
      Right").

      In the event a Transferring Shareholder proposes to Transfer any Shares in
      a transaction subject to this Clause 17.4, it shall notify, or cause to be
      notified, the Remaining Shareholders in writing of each such proposed
      Transfer. Such notice shall set forth: (i) the name of the transferee and
      the amount of Shares proposed to be transferred, (ii) the proposed amount
      and form of consideration and terms and conditions of payment offered by
      the transferee (the "Transferee Terms") and (iii) that the transferee has
      been informed of the Tag Along Right provided for in this Clause 17, if
      such right is applicable, and the total number of Shares the transferee
      has agreed to purchase from the Shareholders in accordance with the terms
      hereof.

                                       31
<PAGE>

     The Tag Along Right may be exercised by each of the Remaining Shareholders
     by delivery of a written notice to the Transferring Shareholder (the "Co-
     sale Notice") within 10 business days following receipt of the notice
     specified in the preceding subsection.  The Co-sale Notice shall state the
     number of Shares owned by such Remaining Shareholder which the Remaining
     Shareholder wishes to include in such Transfer; provided, however, that
     without the written consent of the Transferring Shareholder, the amount of
     such securities belonging to the Remaining Shareholder included in such
     Transfer may not be greater than such Remaining Shareholder's percentage
     beneficial ownership of Fully Diluted Common Shares multiplied by the total
     number of shares of 7 Diluted Common Shares to be sold by both the
     Transferring Shareholder and all Remaining Shareholders.  Upon receipt of a
     Co-sale Notice, the Transferring Shareholder shall be obligated to transfer
     at least the entire number of Shares set forth in the Co-sale Notice to the
     transferee on the Transferee Terms; provided, however, that the
     Transferring Shareholder shall not consummate the purchase and sale of any
     Shares hereunder if the transferee does not purchase all such Shares
     specified in all Co-sale Notices.  If no Co-sale Notice has been delivered
     to the Transferring Shareholder prior to the expiration of the 10 business
     day period referred to above and if the provisions of this Section have
     been complied with in all respects, the Transferring Shareholder shall have
     the right for a 45 day calendar day period to Transfer Shares to the
     transferee on the Transferee Terms without further notice to any other
     party, but after such 45-day period, no such Transfer may be made without
     again giving notice to the Remaining Shareholders of the proposed Transfer
     and complying with the requirements of this Clause 17.

     At the closing of any Transfer of Shares subject to this Clause 17, the
     Transferring Shareholder, and the Remaining Shareholder, in the event such
     Tag Along Right is exercised, shall deliver certificates evidencing such
     securities as have been Transferred by each, duly endorsed, or accompanied
     by written instruments of transfer in form reasonably satisfactory to the
     transferee, free and clear of any adverse claim, against payment of the
     purchase price therefor.

     Notwithstanding the foregoing, this Clause 17 shall not apply to any sale
     of Common Shares pursuant to an effective registration statement under the
     Securities Act in a bona fide public offering.

                                   CLAUSE 19

                                    DISPUTES

19.1 During the Term of this Agreement, should any dispute or difference arise
     amongst the members of the Management Committee, or between Elan and RPI,
     or between Elan or RPI and Newco, the appropriate representatives of the
     applicable Parties shall use good faith efforts to resolve such dispute or
     difference promptly and to the mutual satisfaction of the affected Parties.
     If with respect to any such dispute or difference (but excluding from the
     remaining provisions of this Clause 19 any dispute or difference relating
     to (i) the interpretation of any provision of this Agreement, (ii) the
     interpretation or application of law, or (iii) the ownership of any
     intellectual property, which disputes or differences shall be resolved, if
     at all, by arbitration pursuant to Clause 24.8), such representatives
     cannot reach a resolution to such dispute or difference within a reasonable
     period, then any Party may forthwith give notice to the other Parties that
     it wishes such dispute or difference to be referred to the chief executive
     officer of RPI and the President of Elan Pharmaceutical Technologies.

19.2 In any event of a notice being served in accordance with Clause 19.1, each
     of the Participants shall within 14 days of the service of such notice
     prepare and circulate to the chief executive officer of each Participant a
     memorandum or other form of statement setting out its position on the
     matter in dispute and its reasons for adopting that position.  Each
     memorandum or statement shall be considered by the chief executive officers
     of the Participants who shall endeavor using good faith diligent efforts to
     resolve the dispute.  If the chief executive officers of the Participants
     agree upon a resolution or disposition of the matter, they shall each sign
     a statement which sets out the terms of their agreement.  The Participants
     agree that they shall exercise the voting rights and other powers available
     to them in relation to Newco to procure that the agreed terms are fully and
     promptly carried into effect.

19.3 The chief executive officer of RPI and the President of Elan Pharmaceutical
     Technologies shall, if they are unable to resolve a dispute or difference
     when it is referred to them under Clause 19.1, within sixty (60) days of
     such referral, refer the matter to an independent expert in pharmaceutical
     product development and marketing (including clinical development and
     regulatory affairs) jointly selected by the chief executive officers of the
     Participants (the "Expert").  In the event the chief executive officers of
     the Participants cannot agree upon the designation of the Expert, the
     Participants shall request the American Arbitration Association ("AAA"),
     sitting in the City of New York to select the Expert.  In each case, the
     Expert shall be selected having regard to his suitability to determine the
     particular dispute or difference on which the Expert is being requested to
     determine.  Unless otherwise agreed between the chief executive officers,

                                       34
<PAGE>

     the following rules shall apply to the appointment of the Expert.  The fees
     of the AAA and the Expert shall be shared equally by the Participants. The
     Expert shall be entitled to inspect and examine all documentation and any
     other material which the Expert may consider to be relevant to the dispute.
     The Expert shall afford each Party a reasonable opportunity (in writing or
     orally) of stating reasons in support of such contentions as each Party may
     wish to make relative to the matters under consideration.  The Expert shall
     give notice in writing of his determination to the Parties within such time
     as may be stipulated in his terms of appointment or in the absence of such
     stipulation as soon as practicable but in any event within four weeks from

     binding on the Parties.


                                   CLAUSE 20

                                  TERMINATION

20.1 This Agreement shall govern the operation and existence of Newco until (i)
     terminated by written agreement of all Parties hereto or (ii) otherwise
     terminated in accordance with this Clause 20.

20.2 For the purpose of this Clause 20, a "Relevant Event" is committed or
     suffered by a Participant if:

     20.2.1    it commits a breach of its material obligations under this
               Agreement or the applicable License and fails to remedy it within
               60 days of being specifically required in writing to do so by the
               other Participant; provided, however, that if the breaching
               Participant has proposed a course of action to rectify the breach
               and is acting in good faith to rectify same but has not cured the
               breach by the 60th day, such period shall be extended by such
               period as is reasonably necessary to permit the breach to be
               rectified; or

     20.2.2    a distress, execution, sequestration or other process is levied
               or enforced upon or sued out against a material part of its
               property which is not discharged or challenged within 30 days; or

     20.2.3    it is unable to pay its debts in the normal course of business;
               or

     20.2.4    it ceases wholly or substantially to carry on its business,
               otherwise than for the purpose of a reconstruction or
               amalgamation, without the prior written consent of the other
               Participant (such consent not to be unreasonably withheld); or

     20.2.5    the appointment of a liquidator, receiver, administrator,
               examiner, trustee or similar officer of such Participant or over
               all or substantially all of its assets under

                                       35
<PAGE>

               the law of any applicable jurisdiction, including without
               limitation, the United States of America, Bermuda or Ireland; or

     20.2.6    an application or petition for bankruptcy, corporate re-
               organization, composition, administration, examination,
               arrangement or any other procedure similar to any of the
               foregoing under the law of any applicable jurisdiction, including
               without limitation, the United States of America, Bermuda or
               Ireland, is filed, and is not discharged within 60 days, or a
               Participant applies for or consents to the appointment of a
               receiver, administrator, examiner or similar officer of it or of
               all or a material part of its assets, rights or revenues or the
               assets and/or the business of a Participant are for any reason
               seized, confiscated or condemned.

20.4 If either Participant commits or suffers a Relevant Event, the other
     Participant shall be entitled, within three months of the occurrence of the
     Relevant Event, to require the defaulting Participant (the "Recipient
     Participant") to sell on reasonable terms of payment to the non-defaulting
     Participant (the "Proposing Participant") all (but not some only) of the
     Shares, held or beneficially owned by the Recipient Participant for an
     amount equal to [*] of the fair market value of the Shares of the Recipient
     Participant (the "Buyout Option").

20.5 The Proposing Participant shall notify the Recipient Participant of the
     exercise of the Buyout Option, no later than 30 business days prior to the
     proposed exercise thereof, by delivering written notice to the Recipient
     Participant stating that the Buyout Option is exercised and the price at
     which the Proposing Participant is willing to purchase the Shares of the
     Recipient Participant.

20.6 In the event that the Participants do not agree upon a purchase price for
     the Shares within five Business Days following the receipt by the Recipient
     Participant of written notice from the Proposing Participant pursuant to
     Clause 20.5 above, the Proposing Participant may contact the AAA, sitting
     in New York City and request that an independent US-based arbitrator who is
     knowledgeable of the pharmaceutical/biotechnology industry be appointed
     within 10 Business Days.  The AAA shall endeavor to select an arbitrator
     who is technically knowledgeable in the pharmaceutical/biotechnology
     industry (and who directly and through his affiliates, has no business
     relationship with, or shareholding in, either the Proposing Participant or
     the Recipient Participant).  Promptly upon being notified of the
     arbitrator's appointment, the Proposing Participant and the Recipient
     Participant shall submit to the arbitrator details of their assessment of
     the fair market value for the Shares of the Recipient Participant together
     with such information as they think necessary to validate their assessment.
     The arbitrator shall notify the Recipient Participant of [*] of the fair
     market value assessed by the Proposing Participant (the "Proposing
     Participant Price") and shall notify the Proposing Participant of [*] of
     the fair market value assessed by the Recipient Participant (the "Recipient
     Participant Price"). The Proposing Participant and the Recipient
     Participant shall then be entitled to make further submissions to the
     arbitrator within five Business Days explaining why the Recipient
     Participant Price or the Proposing Participant Price, as the case may be,
     is unjustified. The arbitrator shall thereafter meet with the Proposing
     Participant and the
                                       36
<PAGE>

       Recipient Participant and shall thereafter choose either the Recipient
       Participant Price or the Proposing Participant Price (but not any other
       price) as the purchase price for the Shares (the "Purchase Price") on the
       basis of which price the Expert determines to be closer to [*] of the
       fair market value for the Shares of the Recipient Participant. The
       arbitrator shall use his best efforts to determine the Purchase Price
       within 30 Business Days of his appointment. The Proposing Participant and
       the Recipient Participant shall bear the costs of the arbitrator equally
       provided that the arbitrator may, in his discretion, allocate all or a
       portion of such costs to one Party. Any decision of the arbitrator shall
       be final and binding.

20.7   The Proposing Participant shall purchase the Shares of the Recipient
       Participant by delivery of the Purchase Price in cash no later than the
       15th Business Day following determination of the Purchase Price by the
       Expert.

20.8   The Shares of the Recipient Participant so transferred shall be sold by
       the transferor as beneficial owner with effect from the date of such
       transfer free from any lien, charge or encumbrance with all rights and
       restrictions attaching thereto. If the Proposing Participant elects to
       purchase the Shares of the Recipient Participant, the Shares of the
       Recipient Participant shall be sold by the Recipient Participant as
       beneficial owner for a price equal to [*] of the Purchase Price with
       effect from the date specified by the Proposing Participant in its notice
       of election free from any lien, charge or encumbrance together with all
       rights attaching thereto.

20.9   If the Proposing Participant exercises the Buyout Option, both parties
       will negotiate in good faith to agree to additional reasonable provisions
       and/or amendments to the License Agreements to protect the intellectual
       property rights of the Recipient Party.

20.10  If either Participant commits a Relevant Event, the other Shareholder
       shall have in addition to all other legal and equitable rights and
       remedies hereunder, the right to terminate this Agreement upon 30 days'
       written notice.

20.11  In the event of a termination of the Elan License Agreement and/or the
       RPI License Agreement, both parties will negotiate in good faith to
       determine whether this Agreement should be terminated and if so, which
       provisions should survive termination.

20.12  The provisions of Clauses 1, 3, 5.1, 9, 10, 11, 12, 17, 20.12, 22, 23,
       and 24 shall survive the termination of this Agreement under this Clause
       20.10 or by mutual consent pursuant to Clause 20.1 in accordance with
       their terms; all other terms and provisions of this Agreement shall cease
       to have effect and be null and void upon the termination of this
       Agreement under this Clause 20.10 or by mutual consent pursuant to Clause
       20.1.

                                  SHARE RIGHTS

21.1   The Shareholders agree that the Common Shares and the Preferred Shares
       shall be separate classes of shares and shall carry the respective rights
       and be subject to the restrictions on the transfer and distribution of
       assets provided in the Newco Memorandum of Association and Bye-laws and
       as set forth in this Agreement.

21.2   Except as otherwise provided in the Bermuda Companies Act of 1981 and in
       the Newco Memorandum of Association and Bye-Laws, the Participants agree
       that for a period of two years from the Closing, the Preferred Shares
       issued to EIS shall not carry voting rights in Newco.


                                   CLAUSE 22

                                CONFIDENTIALITY

22.1   The Parties acknowledge and agree that it may be necessary, from time to
       time, to disclose to each other confidential and/or proprietary
       information, including without limitation, inventions, works of
       authorship, trade secrets, specifications, designs, data, know-how and
       other information, relating to the Field, the Products, present or future
       products, the Newco Intellectual Property, the Elan Intellectual Property
       or the RPI Intellectual Property, as the case may be, methods, compounds,
       research projects, work in process, services, sales suppliers, customers,
       employees and/or business of the disclosing Party, whether in oral,
       written, graphic or electronic form (collectively "Confidential
       Information").

22.2   Any Confidential Information revealed by a Party to another Party shall
       be maintained as confidential and shall be used by the receiving Party
       exclusively for the purposes of fulfilling the receiving Party's rights
       and obligations under this Agreement and the License Agreements, and for
       no other purpose. Confidential Information shall not include:

       22.2.1 information that is generally available to the public;

       22.2.2 information that is made public by the disclosing Party;

       22.2.3 information that is independently developed by the receiving
              Party, as evidenced by such Party's records, without the aid,
              application or use of the disclosing Party's Confidential
              Information;

       22.2.4 information that is published or otherwise becomes part of the
              public domain without any disclosure by the receiving Party, or on
              the part of the receiving Party's directors, officers, agents,
              representatives or employees;

                                       38
<PAGE>

     22.2.5 information that becomes available to the receiving Party on a non-
            confidential basis, whether directly or indirectly, from a source
            other than the disclosing Party, which source did not acquire this
            information on a confidential basis; or

     22.2.6 information which the receiving Party is required to disclose
            pursuant to:

            (i)  a valid order of a court or other governmental body or any
                 political subdivision thereof or as otherwise required by law,
                 rule or regulation; or

            (ii) other requirement of law;

                 provided, however, that if the receiving Party becomes legally
                 required to disclose any Confidential Information, the
                 receiving Party shall give the disclosing Party prompt notice
                 of such fact so that the disclosing Party may obtain a
                 protective order or confidential treatment or other appropriate
                 remedy concerning any such disclosure. The receiving Party
                 shall fully co-operate with the disclosing Party in connection
                 with the disclosing Party's efforts to obtain any such order or
                 other remedy. If any such order or other remedy does not fully
                 preclude disclosure, the receiving Party shall make such
                 disclosure only to the extent that such disclosure is legally
                 required; or

     22.2.7 information which was already in the possession of the receiving
            Party at the time of receiving such information, as evidenced by its
            records, provided such information was not previously provided to
            the receiving party from a source which was under an obligation to
            keep such information confidential; or

     22.2.8 information that is the subject of a written permission to disclose,
            without restriction or limitation, by the disclosing Party.

22.3 Each Party agrees to disclose Confidential Information of another Party
     only to those employees, representatives and agents requiring knowledge
     thereof in connection with their duties directly related to the fulfilling
     of the Party's obligations under this Agreement, so long as such persons
     are under an obligation of confidentiality no less stringent than as set
     forth herein.  Each Party further agrees to inform all such employees,
     representatives and agents of the terms and provisions of this Agreement
     and their duties hereunder and to obtain their consent hereto as a
     condition of receiving Confidential Information.  Each Party agrees that it
     will exercise the same degree of care and protection to preserve the
     proprietary and confidential nature of the Confidential Information
     disclosed by a Party, as the receiving Party would exercise to preserve its
     own Confidential Information.  Each Party agrees that it will, upon request
     of another Party, return all documents and any copies thereof containing
     Confidential Information belonging to or disclosed by such other Party.
     Each Party shall promptly notify the other Parties upon discovery of any
     unauthorized use or disclosure of the other Parties' Confidential
     Information.

                                       39
<PAGE>

22.4 Notwithstanding the above, each Party may use or disclose Confidential
     Information disclosed to it by another Party to the extent such use or
     disclosure is reasonably necessary in filing or prosecuting patent
     applications, prosecuting or defending litigation, complying with patent
     applications, prosecuting or defending litigation, complying with
     applicable governmental regulations or otherwise submitting information to
     tax or other governmental authorities, conducting clinical trials, or
     granting a permitted sub-license or otherwise exercising its rights
     hereunder; provided, that if a Party is required to make any such
     disclosure of the other Party's Confidential Information, other than
     pursuant to a confidentiality agreement, such Party shall inform the third
     party recipient of the terms and provisions of this Agreement and their
     duties hereunder and shall obtain their consent hereto as a condition of
     releasing to the third party recipient the Confidential Information.

22.5 Any breach of this Clause 22 by any employee, representative or agent of a
     Party is considered a breach by the Party itself.

22.6 The provisions relating to confidentiality in this Clause 22 shall remain
     in effect during the Term and for a period of seven years following the
     termination of this Agreement.

22.7 The Parties agree that the obligations of this Clause 22 are necessary and
     reasonable in order to protect the Parties' respective businesses, and each
     Party expressly agrees that monetary damages would be inadequate to
     compensate a Party for any breach by the other Party of its covenants and
     agreements set forth herein.  Accordingly, the Parties agree and
     acknowledge that any such violation or threatened violation will cause
     irreparable injury to a Party and that, in addition to any other remedies
     that may be available, in law or in equity or otherwise, any Party shall be
     entitled to obtain injunctive relief against the threatened breach of the
     provisions of this Clause 22, or a continuation of any such breach by the
     other Party, specific performance and other equitable relief to redress
     such breach together with its damages and reasonable counsel fees and
     expenses to enforce its rights hereunder, without the necessity of proving
     actual or express damages.

     Documents.

23.2 All other costs, legal fees, registration fees and other expenses relating
     to the transactions contemplated hereby, including the costs and expenses
     incurred in relation to the incorporation of Newco, shall be borne by

24.8.2.   The Parties will attempt in good faith to resolve any dispute arising
          out of or relating to this Agreement promptly by negotiation between
          executives of the Parties. In the event that such negotiations do not

          consider other dispute resolution mechanisms including mediation.

24.8.3    Any dispute under this Agreement which is not settled by mutual
          consent under Clause 24.8.2 and which relates to (i) the
          interpretation or enforcement of any provision of this Agreement or

          settled by binding arbitration, conducted in accordance with the
          Commercial Arbitration Rules of the American Arbitration Association
          by one arbitrator appointed in accordance with said rules. Such


                                       43
<PAGE>

          arbitrator shall be reasonably satisfactory to each of the Parties;
          provided, that if the Parties are unable to agree upon the identity of

          The arbitration shall be held in New York, New York.

          The arbitrator shall determine what discovery will be permitted,
          consistent with the goal of limiting the cost and time which the

          permit such discovery as they deem necessary to permit an equitable
          resolution of the dispute.

          Any written evidence originally in a language other than English shall
          be submitted in English translation accompanied by the original or a
          true copy thereof.

          Party shall bear its own costs and attorneys' and witness' fees
          incurred in connection with the arbitration.

          In rendering judgment, the arbitrators may not provide for punitive or
          similar exemplary damages.

          A disputed performance or suspended performances pending the
          resolution of the arbitration must be completed within 30 days
          following the final decision of the arbitrators or such other
          reasonable period as the arbitrators determine in a written opinion.

          Any arbitration under this Agreement shall be completed within one
          year from the filing of notice of a request for such arbitration.

          The arbitration proceedings and the decision shall not be made public
          without the joint consent of the Parties and each Party shall maintain
          the confidentiality of such proceedings and decision unless otherwise
          permitted by the other Party.

          The Parties agree that the decision shall be the sole, exclusive and
          binding remedy between them regarding any and all disputes,
          controversies, claims and counterclaims presented to the arbitrators.
          Application may be made to any court having jurisdiction over the
          Party (or its assets) against whom the decision is rendered for a
          judicial recognition of the decision and an order of enforcement.

     commence development of the Products based upon the RPI Intellectual
     Property, the Elan Intellectual Property and/or the Newco Technology (the

     surplus or loan, as may be agreed to by EIS and RPI, up to an aggregate
     maximum amount of U.S.$15,000,000, such funding to be provided by EIS and
     RPI to Newco on a pro rata basis based on their respective equity
     interests, on a fully-diluted basis in Newco.

1.2  The Development Funding shall be provided by EIS and RPI, each in its sole
     discretion, at such times as shall be necessary for the development of the
     Products as provided in the Development Plan or as otherwise approved by
     the Newco Directors, including at least one Newco Director designated by
     EIS and one Newco Director designated by RPI.  The Development Funding
     shall be funded on the following terms:

     1.2.1   The minimum amount of each disbursement of the Development Funding
             shall be U.S.$312,500 (except in the event that an amount less than
             U.S.$312,500 remains available for funding, in which case such
             lesser amount may be funded) allocated between EIS and RPI as
             provided in Section 1.1 above;

     1.2.2   Such funding shall be provided in accordance with the Development
             Plan or as otherwise approved by the Newco Board of Directors

             least one Newco Director designated by RPI); and

     1.2.3   Such funding shall be subject to the receipt by Elan or EIS of any
             required approvals under the Mergers and Takeovers (Control) Acts
             1978-1996 (the "Irish Mergers Act").
                             -----------------

1.3  In the event that Elan or EIS is unable to obtain approval under the Irish
     Mergers Act within three months after a determination of the necessity of
     such funding by the Newco Directors, the parties hereto shall work together
     in good faith, each in its sole discretion, to agree on an alternative
     funding mechanism.

2.   RPI LICENSE TO NEWCO
<PAGE>

2.1. RPI hereby grants to Newco for the Term an exclusive license (including the
     limited right to grant sublicenses under Clause 2.6 below) (the "RPI
     License") to the RPI Intellectual Property to make, have made, import, use,
     offer for sale and sell the Products in the Field in the Territory, subject
     to any contractual obligations that RPI has as of the Effective Date.


2.2  RPI hereby confirms that no obligations are in effect on the date hereof
     between RPI and an unaffiliated third party relating to the Ribozyme for
     use in the Field, other than the Existing RPI License Agreements.

     RPI shall be responsible for payments related to the financial provisions
     and obligations under the RPI Third Party Agreements (including amendments
     thereto), including, without limitation, any royalty or other compensation
     obligations. RPI shall satisfy its responsibility to make such payments by
     offsetting against such payments the royalties that are otherwise due to
     RPI by Newco pursuant to Clause 5 below.

     For the avoidance of doubt, royalties, milestones or other payments which
     arise from the process of the commercialization or exploitation of products
     under the RPI Third Party Agreements (for example, a milestone payment
     payable upon successful completion of Phase II clinical trials, the filing
     of an NDA application, obtaining NDA approval, or first commercial sale)
     shall be payments for which RPI will be responsible under this Clause 2.2.

2.3  To the extent royalty or other compensation obligations that are payable to
     third parties with respect to the RPI Intellectual Property would be
     triggered after the Effective Date, under any third party agreement entered
     into by RPI after the Effective Date (the "RPI Post-Effective Date
     Agreements"), by a proposed use of such RPI Intellectual Property in
     connection with the Project, RPI will inform Newco of such royalty or
     compensation obligations. If Newco agrees to utilize such RPI Intellectual
     Property in connection with the Project, Newco will be responsible for the
     payment of such royalty or other compensation obligations relating thereto.

     For the avoidance of doubt, royalties, milestones or other payments which
     arise from the process of the commercialization or exploitation of products
     under the RPI Post-Effective Date Agreements (for example, a milestone
     payment payable upon successful completion of Phase II clinical trials, the
     filing of an NDA application, obtaining NDA approval, or first commercial
     sale) shall be payments for which Newco will be responsible under this
     Clause 2.3.

2.4  Elan shall be a third party beneficiary under this Agreement and shall have
     the right to cause Newco to enforce Newco's rights under this Agreement
     against RPI.

2.5  Notwithstanding anything contained in this Agreement to the contrary, RPI
     shall have the right outside the Field and subject to the non-competition
     provisions of Clause 4
<PAGE>

     to exploit and grant licenses and sublicenses of the RPI Intellectual
     Property.

     For the avoidance of doubt, Newco shall have no right to use the RPI
     Intellectual Property outside the Field.

2.6  Newco shall not assign any of its rights under the RPI License relating to
     the RPI Intellectual Property without the prior written consent of Elan and
     RPI.

     Newco shall not sublicense any of its rights under the RPI License relating
     to the RPI Intellectual Property without the prior written consent of Elan
     and RPI, which consent shall not be unreasonably withheld or delayed;
     provided, however, that the consent of Elan may be withheld in Elan's sole
     discretion in the case of a proposed sublicense of such rights to a
     Technological Competitor of Elan.

2.7  Any agreement between Newco and any permitted third party for the
     development or exploitation of the RPI Intellectual Property shall require
     such third party to maintain the confidentiality of all information
     concerning the RPI Intellectual Property.

     Insofar as the obligations owed by Newco to RPI are concerned, Newco shall
     remain responsible for all acts and omissions of any permitted sub-
     licensee, including Elan, as if they were acts and omissions by Newco.

3.   INTELLECTUAL PROPERTY

3.1  Ownership of Intellectual Property:
     -----------------------------------

     3.1.1  Newco shall own the Newco Intellectual Property.

     3.1.2  RPI shall own the RPI Intellectual Property.


4.   NON-COMPETITION/AFTER ACQUIRED TECHNOLOGY


4.1  Subject to Clause 4.3, during the Term, RPI, alone or in conjunction with a
     third party, shall not develop or commercialize [ * ] to inhibit the
     translation of [ * ]

4.2  If after the Effective Date RPI acquires know-how or patent rights from a
     third party relating to the System, or if RPI acquires or merges with a
     third party entity that owns or has license rights to know-how or patent
     rights relating to the System, then RPI shall offer to license such know-
     how and patent rights to Newco (subject to existing contractual
     obligations) solely for Newco to research, develop and otherwise engage in
     the commercialization of the Product solely for use in the Field on such
     terms as would be offered to an independent third party negotiating in good
     faith on an arms-length basis.
<PAGE>

4.3  If Newco determines that Newco should not acquire such license as is
     referred to in Clause 4.2, then RPI shall be free to fully exploit such
     know-how and patent rights, with the Elan Intellectual Property licensed to
     Newco, whether inside or outside the Field and to grant to third parties
     licenses and sublicenses with respect thereto.


5.   FINANCIAL PROVISIONS


5.1  Royalties:
     ----------

     The intent of the Parties is to provide for equivalent economic benefit to
     each of RPI and Elan, except in respect of the License Fee (as defined in
     the Elan License Agreement). Accordingly, the Management Committee shall
     decide by unanimous consent on the royalties which shall be payable by
     Newco to RPI and Elan on Net Sales. When determining such royalties, the
     Management Committee shall consider the royalty obligations of RPI under
     the Existing RPI License Agreements, provided that any royalties payable by
     Newco to RPI and Elan hereunder shall be distributed in equal amount to
     each of RPI and Elan. RPI represents and warrants to Newco and Elan that
     RPI's royalty obligations under the Existing RPI License Agreements do not
     exceed an aggregate of [ * ]

5.2  Payment of royalties pursuant to Clause 5.1 shall be made quarterly in
     arrears during each Financial Year within 30 days after the expiry of the
     calendar quarter. The method of payment shall be by wire transfer to an
     account specified by RPI. Each payment made to RPI shall be accompanied by
     a true accounting of all Products sold by Newco's permitted sublicensees,
     if any, during such quarter.

     Such accounting shall show, on a country-by-country and Product-by-Product
     basis, Net Sales (and the calculation thereof) and each calculation of
     royalties with respect thereto, including the calculation of all
     adjustments and currency conversions.

5.3  Newco shall maintain and keep clear, detailed, complete, accurate and
     separate records for a period of 3 years:

     5.3.1  to enable any royalties on Net Sales that shall have accrued
            hereunder to be determined; and


     5.3.2  to enable any deductions made in the Net Sales calculation to be
            determined.

5.4  All payments due hereunder shall be made in United States Dollars. Payments
     due on Net Sales of any Product for each calendar quarter made in a
     currency other than United States Dollars shall first be calculated in the
     foreign currency and then converted to United States Dollars on the basis
     of the exchange rate in effect on the last working day for such quarter for
     the purchase of United States Dollars with such
<PAGE>

     foreign currency quoted in the Wall Street Journal (or comparable
     publication if not quoted in the Wall Street Journal) with respect to the
     currency of the country of origin of such payment, determined by averaging
     the rates so quoted on each business day of such quarter.

5.5  If, at any time, legal restrictions in the Territory prevent the prompt
     payment when due of royalties or any portion thereof, the Parties shall
     meet to discuss suitable and reasonable alternative methods of paying RPI
     the amount of such royalties. In the event that Newco is prevented from
     making any payment under this Agreement by virtue of the statutes, laws,
     codes or government regulations of the country from which the payment is to
     be made, then such payments may be paid by depositing them in the currency
     in which they accrue to RPI's account in a bank acceptable to RPI in the
     country the currency of which is involved or as otherwise agreed by the
     Parties.

5.6  RPI and Newco agree to co-operate in all respects necessary to take
     advantage of any double taxation agreements or similar agreements as may,
     from time to time, be available.

5.7  Any taxes payable by RPI on any payment made to RPI pursuant to this
     Agreement shall be for the account of RPI. If so required by applicable
     law, any payment made pursuant to this Agreement shall be made by Newco
     after deduction of the appropriate withholding tax, in which event the
     Parties shall co-operate to obtain the appropriate tax clearance as soon as
     is practicable. On receipt of such clearance, Newco shall forthwith arrange
     payment to RPI of the amount so withheld.


6.   RIGHT OF INSPECTION AND AUDIT


6.1  Once during each Financial Year, or more often not to exceed quarterly as
     reasonably requested by RPI, Newco shall permit RPI or its duly authorized
     representatives, upon reasonable notice and at any reasonable time during
     normal business hours, to have access to inspect and audit the accounts and
     records of Newco and any other book, record, voucher, receipt or invoice
     relating to the calculation of the royalty payments on Net Sales submitted
     to RPI.

     Any such inspection of Newco's records shall be at the expense of RPI,
     except that if any such inspection reveals a deficiency in the amount of
     the royalty actually paid to RPI hereunder in any Financial Year quarter of
     5% or more of the amount of any royalty actually due to RPI hereunder, then
     the expense of such inspection shall be borne solely by Newco. Any amount
     of deficiency shall be paid promptly to RPI by Newco.

     If such inspection reveals a surplus in the amount of royalties actually
     paid to RPI by Newco, RPI shall reimburse Newco the surplus within 15 days
     after determination.
<PAGE>

6.2  In the event of any unresolved dispute regarding any alleged deficiency or
     overpayment of royalty payments hereunder, the matter will be referred to
     an independent firm of chartered accountants chosen by agreement of RPI and
     Elan for a resolution of such dispute. Any decision by the said firm of
     chartered accountants shall be binding on the Parties.

     notices delivered by any party under the RPI Third Party Agreements, which
     written notices relate to or could affect Newco and/or the transactions

     employees, agents, officers and directors from and against any claims,

            Intellectual Property shall survive the termination of the license
            and sublicense agreements granting said intellectual property rights
            to Newco; and Newco, Elan and RPI shall in good faith agree upon the
            form most advantageous to Elan and RPI in which the rights of Newco
            under any such licenses and sublicenses are to be held (which form
            may include continuation of Newco solely as the holder of such
            licenses or assignment of such rights to a third party or parties,
            including an assignment to both Elan and RPI).

            Any sublicense agreement between Newco and such permitted
            sublicensee shall permit an assignment of rights by Newco and shall
            contain appropriate confidentiality provisions.

9.   CONFIDENTIAL INFORMATION

9.1  The Parties agree that it will be necessary, from time to time, to disclose
     to each other confidential and proprietary information, including without
     limitation, inventions, works of authorship, trade secrets, specifications,
     designs, data, know-how and other proprietary information relating to the
     Field, the Products, processes, services and business of the disclosing
     Party.

     The foregoing shall be referred to collectively as "Confidential
     Information".

9.2  Any Confidential Information disclosed by one Party to another Party shall
     be used by the receiving Party exclusively for the purposes of fulfilling
     the receiving Party's obligations under this Agreement and the JDOA and for
     no other purpose.

9.3  Each Party shall disclose Confidential Information of the other Party only
     to those employees, representatives and agents requiring knowledge thereof
     in connection with fulfilling the Party's obligations under this Agreement.
     Each Party further agrees to inform all such employees, representatives and
     agents of the terms and provisions of this Agreement and their duties
     hereunder and to obtain their agreement hereto as a condition of receiving
     Confidential Information.  Each Party shall exercise the same standard of
     care as it would itself exercise in relation to its own confidential
     information (but in no event less than a reasonable standard of care) to
     protect and preserve the proprietary and confidential nature of the
     Confidential Information disclosed to it by the other Party.  Each Party
     shall, upon request of the other Party, return all documents and any copies
     thereof containing Confidential Information belonging to, or disclosed by,
     such other Party.

9.4  Any breach of this Clause 9 by any person informed by one of the Parties is
     considered a breach by the Party itself.

9.5  Confidential Information shall not be deemed to include:

     9.5.1  information that is in the public domain;

     9.5.2  information which is made public through no breach of this
            Agreement;

     9.5.3  information which is independently developed by a Party as evidenced
            by such Party's records;

     9.5.4  information that becomes available to a Party on a non-confidential
            basis, whether directly or indirectly, from a source other than a
            Party, which source did not acquire this information on a
            confidential basis; or

     9.5.5  information which the receiving Party is required to disclose
            pursuant to:
<PAGE>

               (i)    a valid order of a court or other governmental body; or

               (ii)   any other requirement of law;

               provided that if the receiving Party becomes legally required to
               disclose any Confidential Information, the receiving Party shall
               give the disclosing Party prompt notice of such fact so that the
               disclosing Party may obtain a protective order or other
               appropriate remedy concerning any such disclosure. The receiving
               Party shall fully co-operate with the disclosing Party in
               connection with the disclosing Party's efforts to obtain any such
               order or other remedy. If any such order or other remedy does not
               fully preclude disclosure, the receiving Party shall make such
               disclosure only to the extent that such disclosure is legally
               required.

9.6  The provisions relating to confidentiality in this Clause 9 shall remain in
     effect during the term of this Agreement, and for a period of 7 years
     following the expiration or earlier termination of this Agreement.

9.7  The Parties agree that the obligations of this Clause 9 are necessary and
     reasonable in order to protect the Parties' respective businesses, and each
     Party agrees that monetary damages would be inadequate to compensate a
     Party for any breach by the other Party of its covenants and agreements set
     forth herein.

     Accordingly, the Parties agree that any such violation or threatened
     violation shall cause irreparable injury to a Party and that, in addition
     to any other remedies that may be available, in law and equity or
     otherwise, each Party shall be entitled to obtain injunctive relief against
     the threatened breach of the provisions of this Clause 9, or a continuation
     of any such breach by the other Party, specific performance and other
     equitable relief to redress such breach together with its damages and
     reasonable counsel fees and expenses to enforce its rights hereunder,
     without the necessity of proving actual or express damages.

10.  GOVERNING LAW AND JURISDICTION; ARBITRATION

10.1.  This Agreement shall be governed by and construed in accordance with the
       laws of the State of New York, without giving effect to the provisions
       thereof relating to the conflict of laws.

10.2   The Parties will attempt in good faith to resolve any dispute arising out
       of or relating to this Agreement promptly by negotiation between
       executives of the Parties. In the event that such negotiations do not
       result in a mutually acceptable resolution, the Parties agree to consider
       other dispute resolution mechanisms including mediation.
<PAGE>

       In the event that the Parties fail to agree on a mutually acceptable
       dispute resolution mechanism, any such dispute shall be finally settled
       by arbitration pursuant to Clause 10.3.

10.3   Any dispute under this Agreement which is not settled by mutual consent
       under Clause 10.2 and which relates to (i) the interpretation or
       enforcement of any provision of this Agreement, (ii) the interpretation
       or application of law, or (iii) the ownership of any intellectual
       property shall be finally settled by binding arbitration, conducted in
       accordance with the Commercial Arbitration Rules of the American
       Arbitration Association ("AAA") by one arbitrator appointed in accordance
       with said rules. Such arbitrator shall be an independent expert in
       pharmaceutical product development and marketing (including clinical
       development and regulatory affairs) and shall be reasonably satisfactory
       to each of the Parties; provided, that if the Parties are unable to agree
       upon the identity of such arbitrator within 15 days of demand by either
       Party, then either Party shall have the right to petition the AAA to
       appoint an arbitrator.

       The arbitration shall be held in New York, New York.

       The arbitrator shall determine what discovery will be permitted,
       consistent with the goal of limiting the cost and time which the Parties
       must expend for discovery; provided the arbitrator shall permit such
       discovery as they deem necessary to permit an equitable resolution of the
       dispute.

       Any written evidence originally in a language other than English shall be
       submitted in English translation accompanied by the original or a true
       copy thereof.

       The costs of the arbitration, including administrative and arbitrators'
       fees, shall be shared equally by the Parties and each Party shall bear
       its own costs and attorneys' and witness' fees incurred in connection
       with the arbitration.

       In rendering judgment, the arbitrators may not provide for punitive or
       similar exemplary damages.

       A disputed performance or suspended performances pending the resolution
       of the arbitration must be completed within 30 days following the final
       decision of the arbitrators or such other reasonable period as the
       arbitrators determine in a written opinion.

       Any arbitration under this Agreement shall be completed within one year
       from the filing of notice of a request for such arbitration.

       The arbitration proceedings and the decision shall not be made public
       without the joint consent of the Parties and each Party shall maintain
       the confidentiality of such proceedings and decision unless otherwise
       permitted by the other Party.
<PAGE>

     The Parties agree that the decision shall be the sole, exclusive and
     binding remedy between them regarding any and all disputes, controversies,
     claims and counterclaims presented to the arbitrators.  Application may be
     made to any court having jurisdiction over the Party (or its assets)
     against whom the decision is rendered for a judicial recognition of the
     decision and an order of enforcement.

11.  IMPOSSIBILITY OF PERFORMANCE - FORCE MAJEURE

     Neither RPI nor Newco shall be liable for delay in the performance of any
     of its obligations hereunder if such delay results from causes beyond its
     reasonable control, including, without limitation, acts of God, fires,
     strikes, acts of war, intervention of a government authority, but any such
     delay or failure shall be remedied by such Party as soon as practicable.

12.  ASSIGNMENT

     This Agreement may not be assigned by either Party without the prior
     written consent of the other, save that either Party may assign this
     Agreement to its Affiliates or subsidiaries without such prior written
     consent; provided that such assignment does not have any adverse tax
     consequences on the other Party.

any Person who shall have acquired Registrable Securities from EIS as permitted
herein, either individually or jointly, as the case may be, in a transaction
pursuant to which registration rights are transferred pursuant to Section 10
hereof.

          "Person" shall mean an individual, a partnership, a company, an
           ------
association, a joint stock company, a trust, a joint venture, an unincorporated
organization and a governmental or quasi-governmental entity, or any department,
agency or political subdivision thereof.

          "Registrable Securities" means (i) any shares of Common Stock
           ----------------------
purchased pursuant to the Purchase Agreement, (ii) any shares of Common Stock
issued or issuable upon conversion or exercise of any of the Securities, (iii)
any Common Stock held or acquired by Persons having registration rights as to
such Common Stock as of the date hereof, (iv) the Common Stock into which the
Company's Series L Preferred Stock is convertible, (v) any Common Stock issued
or issuable in respect of the securities referred to in clauses (i) through (iv)
above upon any stock split, stock dividend, recapitalization or similar event;
excluding in all cases, however, any Registrable Securities that have been sold
under Rule 144 promulgated under the Securities Act, and Registrable Securities
sold by a Person in a transaction (including a transaction pursuant to a
registration statement under this Agreement and a transaction pursuant to Rule
144 under the Securities Act) in which registration rights are not transferred
pursuant to Section 10 hereof.

          The terms "register," "registered" and "registration" refer to a
                     --------    ----------       ------------
registration effected by preparing and filing a registration statement in
compliance with the Securities Act.

          "Registration Expenses" shall mean all expenses, other than Selling
           ---------------------
Expenses, incurred by the Company in complying with Sections 2 or 3 hereof,
including without limitation, all registration, qualification and filing fees,

          (a) Requests for Registration In the event that the Company receives
              -------------------------
from the Holder(s) a written request that the Company file a registration
statement on Form S-1 or S-3 (or any successor form to Form S-3), or any other
short-form registration statement, for a public
<PAGE>

offering of Registrable Securities (a "Demand Registration"), the reasonably
                                       -------------------
anticipated aggregate price to the public of which, net of underwriting
discounts and commissions, would be at least $5,000,000, within 10 days after
receipt of any such request, the Company will give written notice of such
requested registration to all other Holders of Registrable Securities. The
Company shall include such other Holders' Registrable Securities in such
offering if they have responded affirmatively within 10 days after the receipt
of the Company's notice. The Holders in aggregate will be entitled to request
one Demand Registration hereunder. A registration will not count as a Demand
Registration until it has become effective (unless such Demand Registration has
not become effective due solely to the fault of the Holders requesting such
registration, including a request by such Holders that such registration be
withdrawn).

          (b) Priority on Demand Registration.  If a Demand Registration is an
              -------------------------------
underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities requested to
be included in such offering exceeds the number of Registrable Securities that
can be sold in such offering without adversely affecting the marketability of
the offering, the Company will include in such registration (x) first such
number of Registrable Securities allocated pro rata among the Holders thereof
and the other Persons holding Registrable Securities based upon the number of
Registrable Securities owned by each such Holder and other Persons holding
Registrable Securities requested to be included in such offering and (y) then
any other shares of Common Stock proposed to be sold by the Company or other
Persons.  No securities other than Registrable Securities hereunder shall be
included in such Demand Registration without the prior written consent of
Holders who collectively hold Registrable Securities representing at least 50%
of the Registrable Securities then outstanding.

          (c) Restrictions on Demand Registration.  The Company may postpone the
              -----------------------------------
filing or the effectiveness of a registration statement for a Demand
Registration one time for up to 90 days if the Company determines in good faith
that such Demand Registration would reasonably be expected to have a material
adverse effect on any proposal or plan by the Company to engage in any
financing, acquisition or disposition of assets (other than in the ordinary
course of business) or any merger, consolidation, tender offer or similar
transaction or would require disclosure of any information that the board of
directors of the Company determines in good faith the disclosure of which would
be detrimental to the Company; provided, that in such event, the Holders
initially requesting such Demand Registration will be entitled to withdraw such
request and, if such request is withdrawn, such Demand Registration will not
count as a permitted Demand Registration hereunder and the Company will pay any
Registration Expenses in connection with such registration.

          (d) Selection of Underwriters.  The Holders will have the right to
              -------------------------
select the investment banker(s) and manager(s) to administer an offering
pursuant to the Demand Registration, subject to any existing agreements of the
Company and to the Company's prior written approval, which will not be
unreasonably withheld or delayed.
<PAGE>

          (e) Other Registration Rights.  Except as provided in this Agreement,
              -------------------------
so long as any Holder owns any Registrable Securities, the Company will not
grant to any Persons the right to request the Company to register any equity
securities of the Company, or any securities convertible or exchangeable into or
exercisable for such securities, which conflicts with the rights granted to the
Holders hereunder, without the prior written consent of the Holders of at least
50% of the Registrable Securities.

          3.  Piggyback Registrations.  (a) Right to Piggyback.   At any time
              -----------------------       -------------------
that the Company shall propose to register Common Stock under the Securities Act
(other than in a registration on Form S-3 relating to sales of securities to
participants in a Company dividend reinvestment plan, S-4 or S-8 or any
successor form or in connection with an acquisition or exchange offer or an
offering of securities solely to the existing shareholders or employees of the
Company), the Company shall give prompt written notice to all Holders of
Registrable Securities of its intention to effect such a registration and,
subject to Section 3(b) and the other terms of this Agreement, shall include in
such registration all Registrable Securities that are permitted under applicable
securities laws to be included in such registration and with respect to which
the Company has received written requests for inclusion therein by the Holders
within 20 days after the receipt of the Company's notice (each, a "Piggyback
                                                                   ---------
Registration"; together with a Demand Registration, a "Registration").
- ------------                                           ------------

          (b) Priority on Piggyback Registrations.  If a Piggyback Registration
              -----------------------------------
is an underwritten registration on behalf of the Company, and the managing
underwriters advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number that
can be sold in such offering without adversely affecting the marketability of
the offering, the Company shall include in such registration, only as may be
permitted in the reasonable business judgment of the managing underwriters for
such registration:

              (i)   first, up to that number of securities the Company proposes
     to sell;

              (ii)  second, up to that number of Registrable Securities
     requested to be included in such registration by the Holders and by any
     other Person, pro rata among the Holders of such Registrable Securities and
     such other Persons, on the basis of the number of shares of Registrable
     Securities of such Holders and other Persons requested to be included in
     such offering; and

              (iii) third, up to that number of other securities requested to
     be included in such registration.

The Holders of any Registrable Securities included in such a registration shall
execute an underwriting agreement and customary accompanying documents in form
and substance satisfactory to the managing underwriters.

          (c) Right to Terminate Registration.  If, at any time after giving
              -------------------------------
written notice
<PAGE>

of its intention to register any of its securities as set forth in Section 3(a)
and prior to the effective date of the registration statement filed in
connection with such registration, the Company shall determine for any reason
not to register such securities, the Company may, at its election, give written
notice of such determination to each Holder of Registrable Securities and
thereupon be relieved of its obligation to register any Registrable Securities
in connection with such registration (but not from its obligation to pay the
Registration Expenses in connection therewith as provided herein).

          (d) Selection of Underwriters.  The Company shall have the right to
              -------------------------
select the investment banker(s) and manager(s) to administer an offering
pursuant to a Piggyback Registration and, subject to the approval of the holders
of a majority of the Registrable Securities which approval will not be
unreasonably withheld or delayed.

          4.  Expenses of Registration.  Except as otherwise provided herein,
              ------------------------
all Registration Expenses incurred in connection with registrations pursuant to
Sections 2 and 3 shall be borne by the Company and all Selling Expenses relating
to securities registered on behalf of the Holders of Registrable Securities
shall be borne by such Holders.

          5.  Holdback Agreements.
              -------------------

          (a) The Company agrees (i) not to effect any public sale or
distribution of its equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, for its own account during the
seven days prior to and during the 90-day period beginning on the effective date
of any underwritten Registration (except (A) as part of such underwritten
registration, (B) pursuant to registration statements on Form S-4 or Form S-8 or
any successor form, (C) pursuant to a registration statement then in effect or
(D) as required under any existing contractual obligation of the Company),
unless the underwriters managing the registered public offering otherwise agree,
and (ii) to cause its officers and directors and to use reasonable efforts to
cause each holder of at least 5% (on a fully-diluted basis) of its outstanding
Common Stock, or any securities convertible into or exchangeable or exercisable
for Common Stock, to agree not to effect any public sale or distribution
(including sales pursuant to Rule 144) of any such securities during such
periods (except as part of such underwritten registration, if otherwise
permitted), unless the underwriters managing the registered public offering
otherwise agree.

          (b) Each Holder agrees, in the event of a public offering by the
Company of Common Stock under a registration statement on Form S-1, S-3 or S-4,
not to effect any offer, sale, distribution or transfer, including a sale
pursuant to Rule 144 (or any similar provision then effect) under the Securities
Act (except as part of such registration), beginning on the date of receipt of a
written notice from the Company setting forth its intention to effect such
registration and ending on the earlier of (i) 180 days from the date of receipt
of such written notice or (ii) 90 days from the effective date of such
Registration Statement; provided, that each of the Persons described in Section
5(a)(ii) shall also have agreed to such restriction on sale.
<PAGE>

          6.  Registration Procedures.  Whenever the Company is under the
              -----------------------
obligation to register Registrable Securities held by the Holders hereunder, the
Company will use all reasonable efforts to effect the Registration and the sale
of such Registrable Securities, and pursuant thereto the Company will as
expeditiously as possible:

          (a) subject to Section 2(c) and 3(a) hereof, prepare and file with the
     Commission a registration statement on any form for which the Company
     qualifies with respect to such Registrable Securities and use all
     reasonable efforts to cause such registration statement to become effective
     (provided that before filing a registration statement or prospectus or any
     amendments or supplements thereto, the Company will (i) furnish to the
     counsel selected by the Holders copies of all such documents proposed to be
     filed, which documents will be subject to the review of such counsel, and
     (ii) notify each Holder of Registrable Securities covered by such
     registration of any stop order issued or threatened by the Commission);

          (b) prepare and file with the Commission 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 for a period equal to the shorter of (i) 120 days and
     (ii) the time by which all securities covered by such registration
     statement have been sold, and comply with the provisions of the Securities
     Act with respect to the disposition of all securities covered by such
     registration statement during such period in accordance with the intended
     methods of disposition by the sellers thereof set forth in such
     registration statement;

          (c) furnish to each seller of Registrable Securities such number of
     copies of such registration statement, each amendment and supplement
     thereto, the prospectus included in such registration statement (including
     each preliminary prospectus) and such other documents as such seller may
     reasonably request in order to facilitate the disposition of the
     Registrable Securities owned by such seller;

          (d) use all reasonable efforts to register or qualify such Registrable
     Securities under the securities or blue sky laws of such jurisdictions as
     any seller reasonably requests and do any and all other acts and things
     which may be reasonably necessary or advisable to enable such seller to
     consummate the disposition in such jurisdictions of the Registrable
     Securities owned by such seller (provided that the Company will not be
     required to (i) qualify generally to do business in any jurisdiction where
     it would not otherwise be required to qualify but for this Section 6(d),
     (ii) subject itself to taxation in any jurisdiction, or (iii) consent to
     general service of process in any such jurisdiction);

          (e) notify each seller of such Registrable Securities, at any time
     when a prospectus relating thereto is required to be delivered under the
     Securities Act, of the occurrence of any event as a result of which the
     prospectus included in such registration
<PAGE>

     statement contains an untrue statement of a material fact or omits any fact
     necessary to make the statements therein not misleading, and, at the
     request of any such seller, the Company will prepare a supplement or
     amendment to such prospectus so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus will not contain
     an untrue statement of a material fact or omit to state any fact necessary
     to make the statements therein not misleading; provided, however, that the
     Company shall not be required to amend the registration statement or
     supplement the Prospectus for a period of up to six months if the board of
     directors of the Company determines in good faith that to do so would
     reasonably be expected to have a material adverse effect on any proposal or
     plan by the Company to engage in any financing, acquisition or disposition
     of assets (other than in the ordinary course of business) or any merger,
     consolidation, tender offer or similar transaction or would require the
     disclosure of any information that the board of directors of the Company
     determines in good faith the disclosure of which would be detrimental to
     the Company, it being understood that the period for which the Company is
     obligated to keep the Registration Statement effective shall be extended
     for a number of days equal to the number of days the Company delays
     amendments or supplements pursuant to this provision. Upon receipt of any
     notice pursuant to this Section 6(e), the Holders shall suspend all offers
     and sales of securities of the Company and all use of any prospectus until
     advised by the Company that offers and sales may resume, and shall keep
     confidential the fact and content of any notice given by the Company
     pursuant to this Section 6(e);

          (f) cause all such Registrable Securities to be listed on each
     securities exchange on which similar securities issued by the Company are
     then listed;

          (g) provide a transfer agent and registrar for all such Registrable
     Securities not later than the effective date of such registration
     statement;

          (h) enter into such customary agreements (including underwriting
     agreements in customary form) and take all such other actions as the
     Holders of a majority of the Registrable  Securities being sold or the
     underwriters, if any, reasonably request in order to expedite or facilitate
     the disposition of such Registrable Securities;

          (i) make available for inspection by a representative of the Holders
     of Registrable Securities included in the registration statement, any
     underwriter participating in any disposition pursuant to such registration
     statement and any attorney, accountant or other agent retained by any such
     seller or underwriter, all pertinent financial and other records, pertinent
     corporate documents and properties of the Company, and cause the Company's
     officers, directors, employees and independent accountants to supply all
     information reasonably requested by any such seller, underwriter, attorney,
     accountant or agent in connection with such registration statement;
<PAGE>

          (j) otherwise use its reasonable efforts to comply with all applicable
     rules and regulations of the Commission, and make available to its security
     holders, as soon as reasonably practicable, an earnings statement covering
     the period of at least 12 months beginning with the first day of the
     Company's first full calendar quarter after the effective date of the
     registration statement, which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

          (k) in the event of the issuance of any stop order suspending the
     effectiveness of a registration statement, or of any order suspending or
     preventing the use of any related prospectus or suspending the
     qualification of any Common Stock included in such registration statement
     for sale in any jurisdiction, use all reasonable efforts promptly to obtain
     the withdrawal of such order; and

          (l) if the registration is an underwritten offering, use all
     reasonable efforts to obtain a so-called "cold comfort" letter from the
     Company's independent public accountants in customary form and covering
     such matters of the type customarily covered by cold comfort letters.

          7.  Obligations of Holders.  Whenever the Holders of Registrable
              ----------------------
Securities sell any Registrable Securities pursuant to a Registration, such
Holders shall be obligated to comply with the applicable provisions of the
Securities Act, including the prospectus delivery requirements thereunder, and
any applicable state securities or blue sky laws.

          8.  Indemnification.  (a) In connection with any registration
              ---------------
statement for a Registration in which a Holder of Registrable Securities is
participating, the Company agrees to indemnify, to the fullest extent permitted
by applicable law, each such Holder of Registrable Securities, its officers and
directors and each Person who controls such Holder (within the meaning of the
Securities Act) against all losses, claims, damages, liabilities, expenses or
any amounts paid in settlement of any litigation, investigation or proceeding
commenced or threatened to which each such indemnified party may become subject
under the Securities Act, including without limitation, attorneys fees and
disbursements (collectively, "Claims") insofar as such Claim arose out of (i)
                              ------
any untrue or alleged untrue statement of material fact contained, on the
effective date thereof, in any such registration statement, prospectus or
preliminary prospectus or any amendment thereof or supplement thereto 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,
except insofar as the same are caused by or contained in any information
furnished in writing to the Company by such Holder expressly for use therein, by
such Holder's failure to deliver a copy of the registration statement or
prospectus or any amendments or supplements thereto after the Company has
furnished such Holder with a sufficient number of copies of the same or by such
Holder's failure to comply with applicable securities laws.  In connection with
an underwritten offering, the Company will indemnify the underwriters, their
officers and directors and each Person who controls the underwriters (within
<PAGE>

the meaning of the Securities Act) to the same extent as provided above with
respect to the indemnification of the Holders of Registrable Securities.

          (b) In connection with any registration statements for a Registration
in which a Holder of Registrable Securities is participating, each such Holder
will furnish to the Company in writing such customary information as the Company
reasonably requests for use in connection with any such registration statement
or prospectus (the "Seller's Information") and, to the fullest extent permitted
                    --------------------
by applicable law, will indemnify the Company, its directors and officers and
each Person who controls the Company (within the meaning of the Securities Act)
against any and all Claims to which each such indemnified party may become
subject under the Securities Act insofar as such Claim arose out of (i) any
untrue or alleged untrue statement of material fact contained, on the effective
date thereof, in any such registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto, (ii) any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements regarding Seller's Information therein not
misleading or (iii) any failure on the part of the Holder to comply with
applicable securities laws; provided, that with respect to a Claim arising
pursuant to clause (i) or (ii) above, the material misstatement or omission is
contained in such Seller's Information; provided, further, that the obligation
to indemnify will be individual to each Holder and will be limited to the amount
of proceeds received by such Holder from the sale of Registrable Securities
pursuant to such registration statement.

          (c) Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (but the failure to provide such notice shall not
release the indemnifying party of its obligation under paragraphs (a) and (b),
unless and then only to the extent that, the indemnifying party has been
prejudiced by such failure to provide such notice) and (ii) unless in such
indemnified party's reasonable judgment, based on written advice of counsel, a
conflict of interest between such indemnified and indemnifying parties may exist
with respect to such claim, permit such indemnifying party to assume the defense
of such claim with counsel reasonably satisfactory to the indemnified party.  An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim will not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party, based on
written advice of counsel, a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

          (d) The indemnifying party shall not be liable to indemnify an
indemnified party for any settlement, or consent to judgment of any such action
effected without the indemnifying party's written consent (but such consent will
not be unreasonably withheld).  Furthermore, the indemnifying party shall not,
except with the prior written approval of each indemnified party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to each
indemnified
<PAGE>

party of a release from all liability in respect of such claim or litigation
without any payment or consideration provided by each such indemnified party.

          (e) If the indemnification provided for in this Section 8 is
unavailable to an indemnified party under clauses (a) and (b) above in respect
of any losses, claims, damages or liabilities referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities in such proportion as is
appropriate to reflect not only the relative benefits received by the Company
(if any), the underwriters, the sellers of Registrable Securities and any other
sellers participating in the registration statement from the sale of shares
pursuant to the registered offering of securities for which indemnity is sought
but also the relative fault of the Company, the underwriters, the sellers of
Registrable Securities and any other sellers participating in the registration
statement in connection with the statement or omission which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Company (if any), the
underwriters, the sellers of Registrable Securities and any other sellers
participating in the registration statement shall be deemed to be based on the
relative relationship of the total net proceeds from the offering (before
deducting expenses) to the Company (if any), the total underwriting  commissions
and fees from the offering (before deducting expenses) to the underwriters and
the total net proceeds from the offering (before deducting expenses) to the
sellers of Registrable Securities and any other sellers participating in the
registration statement.  The relative fault of the Company, the underwriters,
the sellers of Registrable Securities and any other sellers participating in the
registration statement shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the sellers of Registrable Securities and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

          (f) The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling person of such
indemnified party and will survive the transfer of the Registrable Securities.

          9.  Participation in Underwritten Registrations.  No Holder may
              -------------------------------------------
participate in any registration hereunder which is underwritten unless such
Holder (a) agrees to sell such Holder's securities on the basis provided in any
underwriting arrangements approved by the Holder or Holders entitled hereunder
to approve such arrangements, (b) as expeditiously as possible notifies the
Company of the occurrence of any event as a result of which any prospectus
contains an untrue statement of material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading and (c) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.
<PAGE>

          10.  Transfer of Registration Rights. The rights granted to any Holder
               -------------------------------
under this Agreement may be assigned to any permitted transferee of Registrable
Securities, in connection with any transfer or assignment of Registrable
Securities by a Holder; provided, however, that: (a) such transfer is otherwise
effected in accordance with applicable securities laws, (b) if not already a
party hereto, the assignee or transferee agrees in writing prior to such
transfer to be bound by the provisions of this Agreement applicable to the
transferor, and (c) EIS shall act as agent and representative for such Holder
for the giving and receiving of notices hereunder.

          11.  Information by Holder.  Each Holder shall furnish to the Company
               ---------------------
such written information regarding such Holder and any distribution proposed by
such Holder as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Agreement and shall promptly notify the Company
of any changes in such information.

          12.  Exchange Act Compliance.  The Company shall comply with all of
               -----------------------
the reporting requirements of the Exchange Act then applicable to it and shall
comply with all other public information reporting requirements of the
Commission which are conditions to the availability of Rule 144 for the sale of
the Registrable Securities.  The Company shall cooperate with each Holder in
supplying such information as may be necessary for such Holder to complete and
file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

          13.  Termination of Registration Rights.  All registration rights
               ----------------------------------
granted under this Agreement shall terminate and be of no further force and
effect, as to any particular Holder, at such time as all Registrable Securities
held by such Holder have been sold under Rule 144 under the Securities Act.

          14.  Miscellaneous.
               -------------

          (a)  No Inconsistent Agreements.  The Company will not hereafter enter
               --------------------------
into any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the Holders of Registrable Securities in this
Agreement without the prior written consent of a majority in interest of such
Registrable Securities.

          (b)  Remedies.  Any Person having rights under any provision of this
               --------
Agreement  will be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law.  The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement; provided, however, that in no event
<PAGE>

shall any Holder have the right to enjoin, delay or interfere with any offering
of securities by the Company.

          (c) Amendments and Waivers.  Except as otherwise provided herein, the
              ----------------------
provisions of this Agreement may be amended or waived only with the prior
written consent of the Company and Holders of at least 50% of the Registrable
Securities; provided that without the prior written consent of all the Holders,
no such amendment or waiver shall reduce the foregoing percentage required to
amend or waive any provision of this Agreement.

          (d) Successors and Assigns.  All covenants and agreements in this
              ----------------------
Agreement by or on behalf of any of the parties hereto will bind and inure to
the benefit of the respective  successors and assigns of the parties hereto, and
shall inure to the benefit and be enforceable by each Holder of Registrable
Securities from time to time.  In addition, whether or not any express
assignment has been made, the provisions of this Agreement which are for the
benefit of Holders of Registrable Securities are also for the benefit of, and
enforceable by, any permitted transferee of Registrable Securities in accordance
with Section 10 hereof.

          (e) Severability.  Whenever possible, each provision of this Agreement
              ------------
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be prohibited by or
invalid under applicable law, such provision will be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
this Agreement.

          (f) Counterparts.  This Agreement may be executed simultaneously in
              ------------
two or more counterparts, any one of which need not contain the signatures of
more than one party, but all such counterparts taken together will constitute
one and the same Agreement.

          (g) Descriptive Headings.  The descriptive headings of this Agreement
              --------------------
are inserted for convenience only and do not constitute a part of this
Agreement.

          (h) Governing Law.  All questions concerning the construction,
              -------------
validity and interpretation of this Agreement will be governed by the laws of
the State of Delaware without regard to principles of conflicts of laws.

          (i) Notices.  All notices, demands and requests of any kind to be
              -------
delivered to any party in connection with this Agreement shall be in writing and
shall be deemed to have been duly given if personally delivered or if sent by
nationally-recognized overnight courier or by registered or certified airmail,
return receipt requested and postage prepaid or by facsimile transmission,
addressed as follows:

                                R E C I T A L S:

                                                                -------------

                               A G R E A M E N T:

          2.   Demand Registrations.
               --------------------

          (a)  Requests for Registration. From and after the occurrence of the
               -------------------------
initial public offering of the Company's Common Shares under the Securities Act,
any Holder or Holders who collectively hold Registrable Securities representing
at least 5% of the Company's Common Shares on a fully-diluted basis shall have
the right at any time from time to time (subject to the limitations below), to
request registration under the Securities Act of all or part of their
Registrable Securities on Form S-1, S-3 (or any successor form to Form S-1, S-3
or any other short-form registration statement (each, a "Demand Registration").
                                                         -------------------
The request for the

                                       2
<PAGE>

Demand Registration shall specify the approximate number of Registrable
Securities requested to be registered, which must have a minimum expected
aggregate offering price to the public of at least $2,000,000. Within 10 days
after receipt of any such request, the Company will give written notice of such
requested registration to all other Holders of Registrable Securities. The
Company shall include such other Holders' Registrable Securities in such
offering if they have responded affirmatively within 10 days after the receipt
of the Company's notice. Each of EIS and RPI shall be permitted one Demand
Registration. A registration will not count as a Demand Registration until it
has become effective (unless such Demand Registration has not become effective
due solely to the fault of the Holders requesting such registration, including a
request by such Holders that such registration be withdrawn).

          (b)  Priority on Demand Registrations.  If a Demand Registration is an
               --------------------------------
underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if
permitted hereunder, other securities requested to be included in such offering,
exceeds the number of Registrable Securities and other securities, if any, which
can be sold in such offering without adversely affecting the marketability of
the offering, the Company will include in such registration:

               (i) first, the Registrable Securities requested to be included in
     such registration by the Holders (or, if necessary, such Registrable
     Securities pro rata among the Holders thereof based upon the number of
     Registrable Securities owned by each such Holder); and

               (ii) thereafter, other securities requested to be included in
     such registration, as determined by the Company.

          (c)  Restrictions on Demand Registration. The Company may postpone for
               -----------------------------------
up to three months in any 12-month period, the filing or the effectiveness of a
registration statement for a Demand Registration if the Company determines in
good faith that such Demand Registration would reasonably be expected to have a
material adverse effect on any proposal or plan by the Company to engage in any
financing, acquisition or disposition of assets (other than in the ordinary
course of business) or any merger, consolidation, tender offer or similar
transaction or would require disclosure of any information that the board of
directors of the Company determines in good faith the disclosure of which would
be detrimental to the Company; provided, that in such event, the Holders
initially requesting such Demand Registration will be entitled to withdraw such
request and, if such request is withdrawn, such Demand Registration will not
count as a permitted Demand Registration hereunder and the Company will pay any
Registration Expenses in connection with such registration.

                                       3
<PAGE>

          (d)  Selection of Underwriters.  The Holders will have the right to
               -------------------------
select the investment banker(s) and manager(s) to administer an offering
pursuant to the Demand Registration, subject to the Company's prior written
approval, which will not be unreasonably withheld or delayed.

          (e)  Other Registration Rights.  Except as provided in this Agreement,
               -------------------------
so long as any Holder owns any Registrable Securities, the Company will not
grant to any Persons the right to request the Company to register any equity
securities of the Company, or any securities convertible or exchangeable into or
exercisable for such securities, which conflicts with the rights granted to the
Holders hereunder, without the prior written consent of the Holders of at least
50% of the Registrable Securities.

          3.   Piggyback Registrations.
               -----------------------

          (a)  Right to Piggyback.   At any time the Company shall propose to
               -------------------
register Common Shares under the Securities Act (other than in a registration
statement on Form S-3 relating to sales of securities to participants in a
Company dividend reinvestment plan, or Form S-4 or S-8 or any successor form or
in connection with an acquisition or exchange offer or an offering of securities
solely to the existing shareholders or employees of the Company) (each, a

"Piggyback Registration"; together with a Demand Registration, a
 ----------------------
"Registration"), the Company will give prompt written notice to all Holders of
 ------------
Registrable Securities of its intention to effect such a registration and,
subject to Section 3(b) and the other terms of this Agreement, will include in
such registration all Registrable Securities which are permitted under
applicable securities laws to be included in such registration and with respect
to which the Company has received written requests for inclusion therein within
20 days after the receipt of the Company's notice.

          (b)  Priority on Piggyback Registrations.  If a Piggyback Registration
               -----------------------------------
is to be an underwritten offering, and the managing underwriters advise the
Company in writing that in their opinion the number of securities requested to
be included in such registration exceeds the number that can be sold in such
offering without adversely affecting the marketability of the offering, the
Company will include in such registration:

               (i)  first, the securities the Company proposes to sell;

               (ii) the Registrable Securities requested to be included in such
     registration by the Holders and any securities requested to be included in
     such registration by any other Person having equal priority to registration
     with the Holders, pro rata among the Holders of such Registrable Securities
     and such other Persons, on the basis of the number of shares owned by each
     of such Holders; and

               (iii) thereafter, other securities requested to be included in
     such registration.

                                       4
<PAGE>

          The Holders of any Registrable Securities included in such an
underwritten offering must execute an underwriting agreement and customary
accompanying documents in form and substance satisfactory to the managing
underwriters.

          (c)  Right to Terminate Registration.  If, at any time after giving
               -------------------------------
written notice of its intention to register any of its securities as set forth
in Section 3(a) and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any
reason not to register such securities, the Company may, at its election, give
written notice of such determination to each Holder of Registrable Securities
and thereupon be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to
pay the Registration Expenses in connection therewith as provided herein).

          (d)  Selection of Underwriters.  The Company will have the right to
               -------------------------
select the investment banker(s) and manager(s) to administer an offering
pursuant to a Piggyback Registration subject to the approval of the holders of a
majority of the Registrable Securities, which approval will not be unreasonably
withheld or delayed.

          4.   Expenses of Registration.  Except as otherwise provided herein or
               ------------------------
as may otherwise be prohibited by applicable law, all Registration Expenses
incurred in connection with all registrations pursuant to Sections 2 and 3 shall
be borne by the Company; provided that, and notwithstanding anything herein
contained to the contrary, the Company shall not have any obligation pursuant to
the provisions hereof unless and until the Company is able to satisfy (after
taking into account such obligations) the requirements of Section 39A (2A) of
the Bermuda Companies Act of 1981 (or any successor legislation).

          5.   Holdback Agreements.
               -------------------

          (a)  The Company agrees (i) not to effect any public sale or
distribution of its equity securities, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and during the 180-day period beginning on the effective date of any
underwritten Registration or any underwritten Piggyback Registration (except as
part of such underwritten registration or pursuant to registration statements on
Form S-4 or Form S-8 or any successor form), unless the underwriters managing
the registered public offering otherwise agree, and (ii) to cause its officers
and directors and to use reasonable efforts to cause each holder of at least 5%
(on a fully-diluted basis) of its outstanding Common Shares, or any securities
convertible into or exchangeable or exercisable for Common Shares to agree not
to effect any public sale or distribution (including sales pursuant to Rule 144)
of any such securities during such periods (except as part of such underwritten
registration, if otherwise permitted), unless the underwriters managing the
registered public offering otherwise agree.

          (b)  Each Holder agrees, if requested by the managing underwriter or
underwriters in an underwritten offering of securities by the Company, not to
effect any offer,

                                       5
<PAGE>

sale, distribution or transfer, including a sale pursuant to Rule 144 (or any
similar provision then effect) under the Securities Act (except as part of such
underwritten registration), during the seven-day period prior to, and during the
180-day period (or such shorter period as may be agreed to in writing by the
Company and the Holders of at least 50% of the Registrable Securities) following
the effective date of such Registration Statement to the extent timely notified
in writing by the managing underwriter or underwriters; provided, that each of
the Persons described in Section 5(a)(ii) shall also have agreed to such
restriction on sale.

          6.  Registration Procedures.  Whenever the Holders of Registrable
              -----------------------
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company will use all reasonable efforts to effect the
Registration and the sale of such Registrable Securities in accordance with the
intended method of distribution thereof, and pursuant thereto the Company will
as expeditiously as possible:

          (a)  prepare and file with the Commission a registration statement on
any form for which the Company qualifies with respect to such Registrable
Securities and use all reasonable efforts to cause such registration statement
to become effective (provided that before filing a registration statement or
prospectus or any amendments or supplements thereto, the Company will (i)
furnish to the counsel selected by the Holders copies of all such documents
proposed to be filed, which documents will be subject to the review of such
counsel, and (ii) notify each Holder of Registrable Securities covered by such
registration of any stop order issued or threatened by the Commission);

          (b)  prepare and file with the Commission 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 for
a period equal to the shorter of (i) six months and (ii) the time by which all
securities covered by such registration statement have been sold, and comply
with the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement during such period in
accordance with the intended methods of disposition by the sellers thereof set
forth in such registration statement;

          (c)  furnish to each seller of Registrable Securities such number of
copies of such registration statement, each amendment and supplement thereto,
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          (d)  use all reasonable efforts to register or qualify such
Registrable Securities under the securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller (provided that the Company will not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this

                                       6
<PAGE>

Section 6(d), (ii) subject itself to taxation in any jurisdiction, or (iii)
consent to general service of process in any such jurisdiction);

          (e)  notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the occurrence of any event as a result of which the
prospectus included in such registration statement contains an untrue statement
of a material fact or omits any fact necessary to make the statements therein
not misleading, and, at the request of any such seller, the Company will prepare
a supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such prospectus will not contain
an untrue statement of a material fact or omit to state any fact necessary to
make the statements therein not misleading; provided, however, that the Company
shall not be required to amend the registration statement or supplement the
Prospectus for a period of up to six months if the board of directors of the
Company determines in good faith that to do so would reasonably be expected to
have a material adverse effect on any proposal or plan by the Company to engage
in any financing, acquisition or disposition of assets (other than in the
ordinary course of business) or any merger, consolidation, tender offer or
similar transaction or would require the disclosure of any information that the
board of directors of the Company determines in good faith the disclosure of
which would be detrimental to the Company, it being understood that the period
for which the Company is obligated to keep the Registration Statement effective
shall be extended for a number of days equal to the number of days the Company
delays amendments or supplements pursuant to this provision.  Upon receipt of
any notice pursuant to this Section 6(e), the Holders shall suspend all offers
and sales of securities of the Company and all use of any prospectus until
advised by the Company that offers and sales may resume, and shall keep
confidential the fact and content of any notice given by the Company pursuant to
this Section 6(e);

          (f)  cause all such Registrable Securities to be listed on each
securities exchange on which similar securities issued by the Company are then
listed;

          (g)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

          (h)  enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the Holders of
a majority of the Registrable  Securities being sold or the underwriters, if
any, reasonably request in order to expedite or facilitate the disposition of
such Registrable Securities;

          (i)  make available for inspection by a representative of the Holders
of Registrable Securities included in the registration statement, any
underwriter participating in any disposition pursuant to such registration
statement and any attorney, accountant or other agent retained by any such
seller or underwriter, all pertinent financial and other records, pertinent
corporate documents and properties of the Company, and cause the Company's
officers, directors, employees and independent accountants to supply all
information reasonably

                                       7
<PAGE>

requested by any such seller, underwriter, attorney, accountant or agent in
connection with such registration statement;

          (j)  otherwise use its reasonable efforts to comply with all
applicable rules and regulations of the Commission, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least 12 months beginning with the first day of the
Company's first full calendar quarter after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder;

          (k)  in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Common Shares included in such registration statement for sale in any
jurisdiction, use all reasonable efforts promptly to obtain the withdrawal of
such order; and

          (l)  if the registration is an underwritten offering, use all
reasonable efforts to obtain a so-called "cold comfort" letter from the
Company's independent public accountants in customary form and covering such
matters of the type customarily covered by cold comfort letters.

          7.   Obligations of Holders.  Whenever the Holders of Registrable
               ----------------------
Securities sell any Registrable Securities pursuant to a Registration, such
Holders shall be obligated to comply with the applicable provisions of the
Securities Act, including the prospectus delivery requirements thereunder, and
any applicable state securities or blue sky laws.

          8.   Indemnification.  (a) The Company agrees to indemnify, to the
               ---------------
fullest extent permitted by applicable law, each Holder of Registrable
Securities, its officers and directors and each Person who controls such Holder
(within the meaning of the Securities Act) against all losses, claims, damages,
liabilities, expenses or any amounts paid in settlement of any litigation,
investigation or proceeding commenced or threatened to which each such
indemnified party may become subject under the Securities Act, including without
limitation attorneys fees and disbursements (collectively, "Claims") insofar as
                                                            ------
such Claim arose out of (i) any untrue or alleged untrue statement of material
fact contained, on the effective date thereof, in any registration statement,
prospectus or preliminary prospectus or any amendment thereof or supplement
thereto 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, except insofar as the same are caused by or contained in any
information furnished in writing to the Company by such Holder expressly for use
therein, by such Holder's failure to deliver a copy of the registration
statement or prospectus or any amendments or supplements thereto after the
Company has furnished such Holder with a sufficient number of copies of the same
or by such Holder's failure to comply with applicable securities laws.  In
connection with an underwritten offering, the Company will indemnify the
underwriters, their officers and directors and each

                                       8
<PAGE>

Person who controls the underwriters (within the meaning of the Securities Act)
to the same extent as provided above with respect to the indemnification of the
Holders of Registrable Securities.

          (b)  In connection with any registration statements in which a Holder
of Registrable Securities is participating, each such Holder will furnish to the
Company in writing such customary information as the Company reasonably requests
for use in connection with any such registration statement or prospectus (the

"Seller's Information") and, to the fullest extent permitted by applicable law,
- ---------------------
will indemnify the Company, its directors and officers and each Person who
controls the Company (within the meaning of the Securities Act) against any and
all Claims to which each such indemnified party may become subject under the
Securities Act insofar as such Claim arose out of (i) any untrue or alleged
untrue statement of material fact contained, on the effective date thereof, in
any registration statement, prospectus or preliminary prospectus or any
amendment thereof or supplement thereto regarding Seller's Information, (ii) any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein regarding Seller's
Information not misleading or (iii) any failure to comply with applicable
securities laws; provided that with respect to a Claim arising pursuant to
clause (i) or (ii) above, the material misstatement or omission is contained in
such Seller's Information; provided, further, that the obligation to indemnify
will be individual to each Holder and will be limited to the amount of proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
registration statement.

          (c)  Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification (but the failure to provide such notice shall not
release the indemnifying party of its obligation under paragraphs (a) and (b),
unless and then only to the extent that, the indemnifying party has been
prejudiced by such failure to provide such notice) and (ii) unless in such
indemnified party's reasonable judgment, based on written advice of counsel, a
conflict of interest between such indemnified and indemnifying parties may exist
with respect to such claim, permit such indemnifying party to assume the defense
of such claim with counsel reasonably satisfactory to the indemnified party.  An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim will not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party, based on
written advice of counsel, a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

          (d)  The indemnifying party shall not be liable to indemnify an
indemnified party for any settlement, or consent to judgment of any such action
effected without the indemnifying party's written consent (but such consent will
not be unreasonably withheld). Furthermore, the indemnifying party shall not,
except with the prior written approval of each indemnified party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to each
indemnified

                                       9
<PAGE>

party of a release from all liability in respect of such claim or litigation
without any payment or consideration provided by each such indemnified party.

          (e)  If the indemnification provided for in this Section 8 is
unavailable to an indemnified party under clauses (a) and (b) above in respect
of any losses, claims, damages or liabilities referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities in such proportion as is
appropriate to reflect not only the relative benefits received by the Company,
the underwriters, the sellers of Registrable Securities and any other sellers
participating in the registration statement from the sale of shares pursuant to
the registered offering of securities for which indemnity is sought but also the
relative fault of the Company, the underwriters, the sellers of Registrable
Securities and any other sellers participating in the registration statement in
connection with the statement or omission which resulted in such losses, claims,
damages or liabilities, as well as any other relevant equitable considerations.
The relative benefits received by the Company, the underwriters, the sellers of
Registrable Securities and any other sellers participating in the registration
statement shall be deemed to be based on the relative relationship of the total
net proceeds from the offering (before deducting expenses) to the Company, the
total underwriting commissions and fees from the offering (before deducting
expenses) to the underwriters and the total net proceeds from the offering
(before deducting expenses) to the sellers of Registrable Securities and any
other sellers participating in the registration statement. The relative fault of
the Company, the underwriters, the sellers of Registrable Securities and any
other sellers participating in the registration statement shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by the sellers of Registrable
Securities and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

          (f)  The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling person of such
indemnified party and will survive the transfer of the Registrable Securities.

          9.   Participation in Underwritten Registrations.  No Holder may
               -------------------------------------------
participate in any registration hereunder which is underwritten unless such
Holder (a) agrees to sell such Holder's securities on the basis provided in any
underwriting arrangements approved by the Holder or Holders entitled hereunder
to approve such arrangements, (b) as expeditiously as possible notifies the
Company of the occurrence of any event as a result of which any prospectus
contains an untrue statement of material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading and (c) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

          10.  Transfer of Registration Rights.  The rights granted to any
               -------------------------------
Holder under this Agreement may be assigned to any permitted transferee of
Registrable Securities, in connection with any transfer or assignment of
Registrable Securities by a Holder; provided, however, that: (a) such transfer
is otherwise effected in accordance with applicable securities laws, (b) if not
already a party hereto, the assignee or transferee agrees in writing prior to
such transfer to be bound by the provisions of this Agreement applicable to the
transferor, (c) such transferee shall own Registrable Securities representing at
least 5% of the outstanding Common Shares on a fully-diluted basis, and (d) RPI
or EIS, as applicable, if a transferor, shall act as agent and representative
for such Holder for the giving and receiving of notices hereunder.

          11.  Information by Holder.  Each Holder shall furnish to the Company
               ---------------------
such written information regarding such Holder and any distribution proposed by
such Holder as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Agreement and shall promptly notify the Company
of any changes in such information.

          12.  Exchange Act Compliance.  The Company shall comply with all of
               -----------------------
the reporting requirements of the Exchange Act then applicable to it and shall
comply with all other public information reporting requirements of the
Commission which are conditions to the availability of Rule 144 for the sale of
the Registrable Securities.  The Company shall cooperate with each Holder in
supplying such information as may be necessary for such Holder to complete and
file any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

          13.  Termination of Registration Rights.  All registration rights
               ----------------------------------
granted under this Agreement shall terminate and be of no further force and
effect, as to any particular Holder, at such time as all Registrable Securities
held by such Holder have been sold under Rule 144 under the Securities Act.

          14.  Miscellaneous.
               -------------

          (a)  No Inconsistent Agreements.  The Company will not hereafter enter
               --------------------------
into any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the Holders of Registrable Securities in this
Agreement without the prior written consent of a majority in interest of such
Registrable Securities.

          (b)  Remedies.  Any Person having rights under any provision of this
               --------
Agreement  will be entitled to enforce such rights specifically to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law.  The parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce

                                       11
<PAGE>

or prevent violation of the provisions of this Agreement; provided, however,
that in no event shall any Holder have the right to enjoin, delay or interfere
with any offering of securities by the Company.

          (c)  Amendments and Waivers.  Except as otherwise provided herein, the
               ----------------------
provisions of this Agreement may be amended or waived only with the prior
written consent of the Company and Holders of at least 50% of the Registrable
Securities; provided, that without the prior written consent of all the Holders,
no such amendment or waiver shall reduce the foregoing percentage required to
amend or waive any provision of this Agreement.

          (d)  Successors and Assigns.  All covenants and agreements in this
               ----------------------
Agreement by or on behalf of any of the parties hereto will bind and inure to
the benefit of the respective  successors and assigns of the parties hereto, and
shall inure to the benefit and be enforceable by each Holder of Registrable
Securities from time to time.  In addition, whether or not any express
assignment has been made, the provisions of this Agreement which are for the
benefit of Holders of Registrable Securities are also for the benefit of, and
enforceable by, any permitted transferee of Registrable Securities, in
accordance with Section 10 hereof.

          (e)  Severability.  Whenever possible, each provision of this
               ------------
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision will be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

          (f)  Counterparts.  This Agreement may be executed simultaneously in
               ------------
two or more counterparts, any one of which need not contain the signatures of
more than one party, but all such counterparts taken together will constitute
one and the same Agreement.

          (g)  Descriptive Headings.  The descriptive headings of this Agreement
               --------------------
are inserted for convenience only and do not constitute a part of this
Agreement.

          (h)  Governing Law.  All questions concerning the construction,
               -------------
validity and interpretation of this Agreement will be governed by the laws of
the State of Delaware without regard to principles of conflicts of laws.

                        RIBOZYME PHARMACEUTICALS, INC.

       (Pursuant to Section 151of the Delaware General Corporations Law)

     We, ___________ and __________, the Chief Executive Officer and the
Secretary, respectively, of Ribozyme Pharmaceuticals, Inc., a corporation
organized and existing under the Delaware General Corporation Law (the
"Corporation"), in accordance with the provisions of 151 of the Delaware
 -----------
General Corporation Law thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors of the
Corporation by the Certificate of Incorporation of the Corporation, the Board of
Directors of the Corporation on January 6th, 2000 adopted the following
resolution, pursuant to the Corporation's Certificate of Incorporation and
Section 115(g) of the Delaware General Corporation Law, creating one series of
shares of Preferred Stock designated as Series A Preferred Stock and one series
of shares of Preferred Stock designated as Series B Preferred Stock:

     "RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation by the Certificate of Incorporation, the Board of Directors
does hereby provide for the issuance of a series of convertible exchangeable
preferred stock, $0.01 par value, of the Corporation, to be designated "Series A
                                                                       ---------
Preferred Stock", initially consisting of 25,000 shares, and the issuance of a
- ----------------
series of convertible preferred stock, $0.01 par value, of the Corporation, to
be designated "Series B Preferred Stock", initially consisting of 25,000 shares,
               ------------------------
plus in each case, such number of additional shares that may be issuable as
provided herein. To the extent that the designations, powers, preferences and
relative and other special rights and the qualifications, limitations and
restrictions of the Series A Preferred Stock and Series B Preferred Stock are
not stated and expressed in the Certificate of Incorporation, the Board of
Directors of the Corporation does hereby fix and herein state and express such
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions thereof, as follows (all terms used
herein which are defined in the Certificate of Incorporation shall be deemed to
have the meanings provided therein):

                                      I.

     All cross-references in each subparagraph of this Section I refer to other
subparagraphs in this Section I unless otherwise indicated.

     1.   Designation.  25,000 shares of Preferred Stock shall be designated and
          -----------
known as the "Series A Preferred Stock."  Such number of shares may be increased
              ------------------------
or decreased by resolution of the Board of Directors of the Corporation after
obtaining the consent of a majority in interest of the holder(s) of the then-
outstanding shares of Series A Preferred Stock; provided, that no decrease shall
reduce the number of shares of Series A Preferred Stock to a number less
<PAGE>

than the number of shares then outstanding plus the number of such shares
issuable upon exercise of outstanding rights, options or warrants or upon
conversion of outstanding securities issued by the Corporation.

     2.   Dividend Provisions.  Each share of Series A Preferred Stock, for a
          -------------------
period of six years from the date of first issuance of the Series A Preferred
Stock, shall be entitled to receive a mandatory dividend equal to 6.0% per year
of the Original Issue Price (as defined below) thereof. Such dividend shall (1)
shall compound on a semi-annual basis, the first compounding to commence six
months from the date hereof, and (2) be payable semi-annually on each succeeding
six and 12 month anniversary of the first issuance, solely by the issuance of
additional shares of Series A Preferred Stock, at a price per share equal to the
Original Issue Price thereof, and not in cash.  Fractional shares of Series A
Preferred Stock shall be issuable for purposes hereunder.

     3.   Seniority; Liquidation Preference.
          ----------------------------------

          (a)   The Series A Preferred Stock, as to its liquidation preference,
shall rank senior to or pari passu with any future class or series of Preferred
Stock issued by the Company; pari passu with the Series B Convertible Stock, par
value  $0.01 per share (the "Series B Preferred Stock"); senior to the Company's
                             ------------------------
Common Stock and junior to the Company's Series L Preferred Stock.

          (b)   In the event of any liquidation, dissolution or winding-up of
the affairs of the Corporation, whether voluntary or involuntary, (collectively,
a "Liquidation"), before any payment of cash or distribution of other property
   -----------
shall be made to the holders of the Common Stock or any other class or series of
stock subordinate in liquidation preference to the Series A Preferred Stock, the
holders of the Series A Preferred Stock and the Series B Preferred Stock, on a
pro rata basis based on their aggregate liquidation preferences then
outstanding, shall be entitled to receive out of the assets of the Corporation
legally available for distribution to its shareholders, the Original Issue Price
per share (as appropriately adjusted for any combinations or divisions or
similar recapitalizations affecting the Series A Preferred Stock after issuance)
and accrued and unpaid dividends thereon (the "Series A Liquidation
                                               --------------------
Preference").  As used herein, the "Original Issue Price" per share is $1,000.
- ----------                          --------------------

          (c)   If, upon any Liquidation, the assets of the Corporation
available for distribution to its shareholders shall be insufficient to pay the
holders of the Series A Preferred Stock and the Series B  Preferred Stock the
full amounts to which they shall be entitled, the holders of the Series A
Preferred Stock and the  Series B Preferred  Stock shall share ratably (based on
their respective outstanding aggregate  liquidation preferences) in any
distribution of assets in proportion to the respective amounts which would be
payable to them in respect of the shares held by them if all amounts payable to
them in respect of such were paid in full pursuant to Section 3(b).

          (d)   After the distributions described in Section 3(c) above have
been paid, subject to the rights of other series of preferred stock that exist
or may from time to time come

                                       2
<PAGE>

into existence, the remaining assets of the Corporation available for
distribution to shareholders shall be distributed among the holders of Common
Stock pro rata based on the number of shares of Common Stock held by each.

     4.   Conversion.  The holders of the Series A Preferred Stock shall have
          ----------
conversion rights the "Series A Conversion Right"), through and including the
                       -------------------------
date that is six years after the first issuance of the Series A Preferred Stock
(the "Conversion Termination Date"):
      ---------------------------

          (a)  Right to Convert.
               ----------------

               (i)  Each share of Series A Preferred Stock shall be convertible,
          at the option of the holder thereof, at any time that is two years
          after the issuance thereof, at the office of the Corporation or any
          transfer agent for such stock, into such number of fully paid and non-
          assessable shares of Common Stock as is determined by dividing (x) the
          sum of the Original Issue Price of such share of Series A Preferred
          Stock and all accrued and unpaid dividends thereon by (y) the Series A
          Conversion Price (as defined below). The "Series A Conversion Price"
                                                    -------------------------
          shall be (w) $12.00; provided, that such conversion occurs on or prior
          to the date that is three years after the date of issuance, (x)
          $13.20; provided that such conversion occurs after the date that is
          three years after the date of issuance but on or prior to the date
          that is four years after the date of issuance, (y) $14.40; provided
          that such conversion occurs after the date that is fours years after
          the date of issuance by on or prior to the date that is five years
          after the date of issuance and (z) $15.00; provided that such
          conversion occurs after the date that is five years after the date of
          issuance (and the Series A Conversion Price shall be subject to
          adjustment as set forth below in this Section 4(a)).  Notwithstanding
          the above, the holder(s) of the Series A Preferred Stock shall have
          the right, at the option of such holder(s), at any time within the
          two-year period after the issuance thereof, to cause the Company
          automatically to convert the Series A Preferred Stock into shares of
          Common Stock at the Series A Conversion Price then in effect, upon the
          occurrence of any of the following:  (i) a merger, consolidation or
          similar transaction involving the Corporation or (ii) the transactions
          involving the Corporation in a share-for-share merger or similar
          transaction.

               (ii) Before any holder of Series A Preferred Stock shall be
          entitled to convert such shares into shares of Common Stock, such
          holder shall surrender the certificate or certificates therefor, duly
          endorsed, at the office of the Corporation or of any transfer agent
          for the Series A Preferred Stock, and shall give written notice to the
          Corporation at its principal corporate office, of the election to
          convert the same and shall state therein the name or names in which
          the certificate or certificates for shares of Common Stock are to be
          issued. The Corporation shall, as soon as practicable thereafter,
          issue and deliver at such office to such holder of Series A Preferred
          Stock, or to the nominee or nominees of such holder, a certificate or
          certificates for the number of shares of Common Stock to which such
          holder shall be entitled as set forth above. Such conversion shall be
          deemed

                                       3
<PAGE>

          to have been made immediately prior to the close of business on the
          date of such surrender of the shares of Series A Preferred Stock to be
          converted, and the person or persons entitled to receive the shares of
          Common Stock issuable upon such conversion shall be treated for all
          purposes as the record holder or holders of such shares of Common
          Stock as of such date.

               (iii)  In the event the Corporation should at any time fix a
          record date for the effectuation of a split or subdivision of the
          outstanding shares of Common Stock or the determination of holders of
          Common Stock entitled to receive a dividend or other distribution
          payable in additional shares of Common Stock or other securities or
          rights convertible into, or entitling the holder thereof to receive
          directly or indirectly, additional shares of Common Stock (hereinafter
          referred to as "Common Stock Equivalents") without payment of any
                          ------------------------
          consideration by such holder for the additional shares of Common Stock
          or the Common Stock Equivalents (including the additional shares of
          Common Stock issuable upon conversion or exercise thereof) or with
          payment that is less than the Series A Conversion Price then in
          effect, then, as of such record date (or the date of such dividend
          distribution, split or subdivision if no record date is fixed), the
          Series A Conversion Price of the Series A Preferred Stock shall be
          appropriately decreased so that the number of shares of Common Stock
          issuable on conversion of each share of such series shall be increased
          in proportion to such increase of the aggregate of (a) shares of
          Common Stock outstanding and (b) those issuable with respect to such
          Common Stock Equivalents, with the number of shares issuable with
          respect to Common Stock Equivalents determined from time to time as
          provided in Section 4(a)(v) below.

               (iv)   If the number of shares of Common Stock outstanding at any
          time is decreased by a combination of the outstanding shares of Common
          Stock, then, following the record date of such combination, the Series
          A Conversion Price for the Series A Preferred Stock shall be
          appropriately increased so that the number of shares of Common Stock
          issuable on conversion of each share of such series shall be decreased
          in proportion to such decrease in outstanding shares.

               (v)    The following provisions shall apply for purposes of this
          Section 4(a):

               (A)    The aggregate maximum number of shares of Common Stock
          deliverable upon conversion or exercise of Common Stock Equivalents
          (assuming the satisfaction of any conditions to convertibility or
          exercisability, including, without limitation, the passage of time,
          but without taking into account potential antidilution adjustments)
          shall be deemed to have been issued at the time such Common Stock
          Equivalents were issued.

               (B)    In the event of any change in the number of shares of
          Common Stock deliverable or in the consideration payable to the
          Corporation upon

                                       4
<PAGE>

          conversion or exercise of such Common Stock Equivalents including, but
          not limited to, a change resulting from the antidilution provisions
          thereof, the Series A Conversion Price of the Series A Preferred
          Stock, to the extent in any way affected by or computed using such
          Common Stock Equivalents, shall be recomputed to reflect such change,
          but no further adjustment shall be made for the actual issuance of
          Common Stock or any payment of such consideration upon the exercise of
          any such options or rights or the conversion or exchange of such
          securities.

               (C) Upon the termination or expiration of the convertibility or
          exercisability of any such Common Stock Equivalents, the Series A
          Conversion Price of the Series A Preferred Stock, to the extent in any
          way affected by or computed using such Common Stock Equivalents, shall
          be recomputed to reflect the issuance of only the number of shares of
          Common Stock (and Common Stock Equivalents which remain convertible or
          exercisable) actually issued upon the conversion or exercise of such
          Common Stock Equivalents.

5.   Exchange Right. Provided that (a) all of the shares of Series A Preferred
     --------------
Stock initially issued and sold by the Corporation to Elan International
Services, Ltd., a Bermuda exempted limited liability company ("EIS"), have not
                                                               ---
been converted, as provided in Section 4 above, and (b) the Exchange Termination
Date (as defined below) shall not have occurred, the holders of the Series A
Preferred Stock (acting by act of the majority holders thereof) shall have the
right to exchange all of their shares of Series A Preferred Stock (the "Exchange
                                                                        --------
Right") of the Corporation for initially 3,612 shares of non-voting convertible
- -----
preferred shares (the "Preferred Shares") (as adjusted for any combinations or
                       ----------------
divisions or similar recapitalizations) of Medizyme Pharmaceutical Ltd., a
Bermuda exempted limited liability company ("Newco"), held by the Corporation,
                                             -----
so that, in any event, after giving effect to the exercise of the Exchange
Right, EIS and the Corporation will each hold 50% of the total outstanding share
capital of Newco, on a fully diluted basis, assuming that neither EIS nor the
Corporation has sold any shares of Newco.  Upon exercise of the Exchange Right,
the Preferred Shares held by the Corporation shall be transferred legally and
beneficially to EIS.

          The rights of the holders to exercise the Exchange Right shall
commence at any time after the date that is 24 months after the first issuance
of the Series A Preferred Stock and shall terminate and be of no further force
and effect on the date that is the later of (i) seven months thereafter and (ii)
the completion of Newco's development period, as agreed in the business plan of
Newco and as set forth in the Subscription, Joint Development and Operating
Agreement dated as of January 7th, 2000, among  Elan Pharmaceuticals
Technologies, a division of Elan Corporation, plc, an Irish public limited
company, EIS, Elan Pharma International Limited, an Irish corporation, Newco and
the Corporation (the "Exchange Termination Date").
                      -------------------------

          Upon exercise of the Exchange Right, the shares of Series A Preferred
Stock originally purchased from the Corporation, but not including any of the
accrued and unpaid dividends thereon (all of which shall remain outstanding),
shall be canceled and shall no longer be entitled to any rights in the
Corporation.

                                       5
<PAGE>

          If any shares of the Series A Preferred Stock (other than shares in
respect of accrued dividends) are converted pursuant to Section 4(a), to shares
of Common Stock, the Exchange Right with respect to the shares of Series A
Preferred Stock originally purchased from the Corporation, but not including any
of the accrued and unpaid dividends thereon, shall be canceled and shall no
longer be entitled to any rights in the Corporation.

               In order to exercise the Exchange Right, the holders shall
provide written notice thereof to the Corporation, setting forth (a) the fact
that such holders intend to exercise the Exchange Right, and (b) the proposed
date for such exercise (the "Exercise Date"), which shall be between 10 and 30
                             -------------
days after the date of such notice. On the Exercise Date, (y) the holders shall
tender their shares of Series A Preferred Stock to the Corporation for
cancellation, and (z) the Corporation shall cause to be delivered to EIS, acting
on behalf of such holders, such shares of Newco. The holders and the Corporation
shall take all other necessary or appropriate actions in connection with or to
effect such closing.

          Section 5(c) of the Securities Purchase Agreement, dated as of January
7th, 2000, between EIS and the Corporation contains certain additional
provisions relating to the Exchange Right.

     6.   Other Distributions.  On or prior to the Conversion Termination Date,
          -------------------
in the event the Corporation shall declare a distribution payable in securities
of other entities, evidences of indebtedness issued by the Corporation or other
entities, assets (excluding cash dividends) or options or rights not referred to
in Section 4, then, in each such case for the purpose of this Section 6, the
holders of the Series A Preferred Stock shall be entitled to a proportionate
share of any such distribution as though they were the holders of the number of
shares of Common Stock of the Corporation into which their shares of Series A
Preferred Stock would be convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

     7.   Recapitalizations.  On or prior to the Conversion Termination Date, if
          -----------------
at any time or from time to time there shall be a recapitalization of the Common
Stock (other than a subdivision, combination or merger or sale of assets
provided for in Section 3 or Section 4 hereof) provision shall be made so that
the holders of the Series A Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series A Preferred Stock the number of shares of
stock or other securities or property of the Corporation or otherwise, to which
a holder of Common Stock deliverable upon conversion would have been entitled on
such recapitalization.  In any such case, appropriate adjustment shall be made
in the application of the provisions of Section 4 with respect to the rights of
the holders of the Series A Preferred Stock after the recapitalization to the
end that the provisions of Section 4 (including adjustment of the Series A
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series A Preferred Stock) shall be applicable after that event
as nearly equivalent as may be practicable.

                                       6
<PAGE>

     8.   No Impairment.  The Corporation will not, by amendment of its
          -------------
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issuance or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by the
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions hereof and in the taking of all such action as may be
necessary or appropriate in order to protect the Series A Conversion Right and
Exchange Right of the holders of the Series A Preferred Stock against
impairment.

     9.   No Fractional Shares and Certificate as to Adjustments.
          ------------------------------------------------------

          (a)   No fractional shares shall be issued upon the conversion of any
share or shares of the Series A Preferred Stock, and the number of shares of
Common Stock to be issued shall be rounded to the nearest whole share.  Whether
or not fractional shares are issuable upon such conversion shall be determined
on the basis of the aggregate number of shares of Series A Preferred Stock each
holder is at the time converting into Common Stock and the aggregate number of
shares of Common Stock issuable to each such holder upon such conversion.

          (b)   Upon the occurrence of each adjustment or readjustment of the
Series A Conversion Price pursuant to Section 4, the Corporation, at its
expense, shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and prepare and furnish to each holder of shares of Series
A Preferred Stock a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.  The Corporation shall, upon the written request at any time of any
holder of Series A Preferred Stock, furnish or cause to be furnished to such
holder a like certificate setting forth (i) such adjustment and readjustment,
(ii) the Series A Conversion Price at the time in effect, and (iii) the number
of shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of a share of Series A Preferred
Stock.

     10.  Reservation of Stock Issuable Upon Conversion.  The Corporation shall
          ---------------------------------------------
at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Preferred Stock, such number of its shares of Common
Stock that shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock not otherwise reserved
for issuance shall not be sufficient to effect the conversion of all then
outstanding shares of the Series A Preferred Stock, in addition to such other
remedies as shall be available to the holders of such Series A Preferred Stock,
the Corporation will take such corporate action that may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes,
including without limitation, engaging in best efforts to obtain the requisite
shareholder approval of any necessary amendment to its Certificate of
Incorporation.

     11.  Notices.  Any notice required by the provisions hereof to be given to
          -------
the holders of shares of Series A Preferred Stock shall be deemed given on the
date of service if served

                                       7
<PAGE>

personally on the party to whom notice is to be given, or on the date of
transmittal of services by facsimile transmission to the party to whom notice is
to be given, and addressed to each holder of record at his address appearing on
the books of the Corporation.

     12.    Voting Rights.  Subject to Section 13 below, holders of Series A
            -------------
Preferred Stock shall not be entitled to vote, including with respect to the
election of directors of the Corporation.

     13.    Protective Provisions.  Subject to the rights of any series of
            ---------------------
preferred stock that exist or may from time to time come into existence, so long
as any shares of Series A Preferred Stock are outstanding, the Corporation shall
not without first obtaining the approval (by vote or written consent, as
provided by law) of the holders of at least a majority of the then-outstanding
shares of Series A Preferred Stock, voting separately as a series:

            (a)   amend its Certificate of Incorporation so as to affect
adversely the shares of Series A Preferred Stock or any holder thereof
(including by creating any additional classes or series of preferred stock with
a liquidation preference or other rights senior to the Series A Preferred
Stock); or

            (b)   change the rights of the holders of the holders of the Series
A Preferred Stock in any other respect.

     14.    Status of Converted Stock.  In the event any shares of Series A
            -------------------------
Preferred Stock shall be converted pursuant to Section 4 or exchanged pursuant
to Section 5 hereof, the shares so converted or exchanged shall be canceled and
shall not be reissuable by the Corporation.  The Certificate of Incorporation of
the Corporation shall be appropriately amended to effect the corresponding
reduction in the Corporation's authorized capital stock."

     15.    Term.  In the event that the Series A Preferred Stock shall not have
            ----
been converted into shares of Common Stock or exchanged, as provided in Section
5 above, on or prior to the date that is the later of (A) six years after the
date hereof and (B) the Exchange Termination Date, the Series A Preferred Stock
shall either, at the option of the Corporation, (i) remain outstanding or (ii)
be repaid in amount equal to the Series A Liquidation Preference plus accrued
dividends thereon, in cash or by the issuance of shares at the Corporation's
Common Stock based on the then-current Conversion Price.
                                      II.
     All cross-references in each subparagraph of this Section II refer to other
subparagraphs in this Section II unless otherwise indicated.

     1.     Designation.  25,000 shares of Preferred Stock shall be designated
            -----------
and known as the "Series B Preferred Stock." Such number of shares may be
                  ------------------------
increased or decreased by resolution of the Board of Directors of the
Corporation after obtaining the consent of a majority in interest of the
holder(s) of the then-outstanding shares of Series B Preferred Stock; provided,
that no decrease shall reduce the number of shares of Series B Preferred Stock
to a number less than the number of shares then outstanding plus the number of
such shares issuable upon

                                       8
<PAGE>

exercise of outstanding rights, options or warrants or upon conversion of
outstanding securities issued by the Corporation.

     2.   Dividend Provisions.
          -------------------

     Each share of Series B Preferred Stock, for a period of six years from the
date of first issuance of the Series B Preferred Stock, shall be entitled to
receive a mandatory dividend equal to 12.0% per year of the Original Issue Price
(as defined below) thereof. Such dividend shall (1) shall compound on a semi-
annual basis, the first compounding to commence six months from the date hereof,
and (2) be payable semi-annually on each succeeding six and 12-month anniversary
of the first issuance, solely by the issuance of additional shares of Series B
Preferred Stock, at a price per share equal to the Original Issue Price thereof,
and not in cash.  Fractional shares of Series B Preferred Stock shall be
issuable for purposes hereunder.

     3.   Seniority; Liquidation Preference.
          ----------------------------------

          (a)   The Series B Preferred Stock, as to its liquidation preference,
shall rank senior to or pari passu with any existing or future class or series
of Preferred Stock issued by the Company; pari passu with the Series A
Convertible Exchangeable Preferred Stock, par value $0.01 per share (the "Series
                                                                          ------
A Preferred Stock") and senior to the Company's Common Stock.
- -----------------

          (b)   In the event of any liquidation, dissolution or winding-up of
the affairs of the Corporation, whether voluntary or involuntary, (collectively,
a "Liquidation"), before any payment of cash or distribution of other property
   -----------
shall be made to the holders of the Common Stock or any other class or series of
stock subordinate in liquidation preference to the Series B Preferred Stock, the
holders of the Series A Preferred Stock and Series B Preferred Stock, on a pro
rata basis  based  on their aggregate liquidation preferences then outstanding
shall be entitled to receive out of the assets of the Corporation legally
available for distribution to its shareholders, the Original Issue Price per
share (as appropriately adjusted for any combinations or divisions or similar
recapitalizations affecting the Series B Preferred Stock after issuance) and
accrued and unpaid dividends thereon (the "Series B Liquidation Preference").
                                           -------------------------------
As used herein, the "Original Issue Price" per share is $1,000.
                     --------------------

          (c)   If, upon any Liquidation, the assets of the Corporation
available for distribution to its shareholders shall be insufficient to pay the
holders of the Series A Preferred Stock and Series B Preferred Stock the full
amounts to which they shall be entitled, the holders of the Series A Preferred
Stock and Series B Preferred Stock shall share ratably (based on their
respective outstanding aggregate liquidation preferences) in any distribution of
assets in proportion to the respective amounts which would be payable to them in
respect of the shares held by them if all amounts payable to them in respect of
such were paid in full pursuant to Section 3(b).

          (d)   After the distributions described in Section 3(c) above have
been paid, subject to the rights of other series of preferred stock that exist
or may from time to time come into existence, the remaining assets of the
Corporation available for distribution to shareholders

                                       9
<PAGE>

shall be distributed among the holders of Common Stock pro rata based on the
number of shares of Common Stock held by each.

     4.   Conversion.  The holders of the Series B Preferred Stock shall have
          ----------
conversion rights (the "Series B Conversion Right"), through and including the
                        -------------------------
date that is six years after the first issuance of any shares of Series B
Preferred Stock (the "Conversion Termination Date"):
                      ---------------------------

          (a)  Right to Convert.
               ----------------

               (i)    Each share of Series B Preferred Stock shall be
          convertible, at the option of the holder thereof, at any time, at the
          office of the Corporation or any transfer agent for such stock, into
          such number of fully paid and non-assessable shares of Common Stock as
          is determined by dividing (x) the sum of the Original Issue Price of
          such share of Series B Preferred Stock and all accrued and unpaid
          dividends thereon by (y) the Series B Conversion Price (as defined
          below). The "Series B Conversion Price" shall for each issue of Series
                       -------------------------
          B Preferred Stock be a price equal to 150% of the average closing
          price of the Common Stock for the 60 trading days prior to the date of
          written notice of such purchase request of the Company for the
          purchase of such issue of Series B Preferred Stock.

               (ii)   Before any holder of Series B Preferred Stock shall be
          entitled to convert such shares into shares of Common Stock, such
          holder shall surrender the certificate or certificates therefor, duly
          endorsed, at the office of the Corporation or of any transfer agent
          for the Series B Preferred Stock, and shall give written notice to the
          Corporation at its principal corporate office, of the election to
          convert the same and shall state therein the name or names in which
          the certificate or certificates for shares of Common Stock are to be
          issued. The Corporation shall, as soon as practicable thereafter,
          issue and deliver at such office to such holder of Series B Preferred
          Stock, or to the nominee or nominees of such holder, a certificate or
          certificates for the number of shares of Common Stock to which such
          holder shall be entitled as set forth above. Such conversion shall be
          deemed to have been made immediately prior to the close of business on
          the date of such surrender of the shares of Series B Preferred Stock
          to be converted, and the person or persons entitled to receive the
          shares of Common Stock issuable upon such conversion shall be treated
          for all purposes as the record holder or holders of such shares of
          Common Stock as of such date.

               (iii)  In the event the Corporation should at any time fix a
          record date for the effectuation of a split or subdivision of the
          outstanding shares of Common Stock or the determination of holders of
          Common Stock entitled to receive a dividend or other distribution
          payable in additional shares of Common Stock or Common Stock
          Equivalents without payment of any consideration by such holder for
          the additional shares of Common Stock or the Common Stock Equivalents
          (including the additional shares of Common Stock issuable upon
          conversion or exercise thereof) or with payment that is less than the
          Series B Conversion Price

                                       10
<PAGE>

          then in effect, then, as of such record date (or the date of such
          dividend distribution, split or subdivision if no record date is
          fixed), the Series B Conversion Price of the Series B Preferred Stock
          shall be appropriately decreased so that the number of shares of
          Common Stock issuable on conversion of each share of such series shall
          be increased in proportion to such increase of the aggregate of (a)
          shares of Common Stock outstanding and (b) those issuable with respect
          to such Common Stock Equivalents, with the number of shares issuable
          with respect to Common Stock Equivalents determined from time to time
          as provided in Section 4(a)(v) below.

               (iv)  If the number of shares of Common Stock outstanding at any
          time is decreased by a combination of the outstanding shares of Common
          Stock, then, following the record date of such combination, the Series
          B Conversion Price for the Series B Preferred Stock shall be
          appropriately increased so that the number of shares of Common Stock
          issuable on conversion of each share of such series shall be decreased
          in proportion to such decrease in outstanding shares.

               (v)   The following provisions shall apply for purposes of this
          Section 4(a):

          (assuming the satisfaction of any conditions to convertibility or
          exercisability, including, without limitation, the passage of time,
          but without taking into account potential antidilution adjustments)
          shall be deemed to have been issued at the time such Common Stock
          Equivalents were issued.

                     (B) In the event of any change in the number of shares of
          Common Stock deliverable or in the consideration payable to the
          Corporation upon conversion or exercise of such Common Stock
          Equivalents including, but not limited to, a change resulting from the
          antidilution provisions thereof, the Series B Conversion Price of the
          Series B Preferred Stock, to the extent in any way affected by or
          computed using such Common Stock Equivalents, shall be recomputed to
          reflect such change, but no further adjustment shall be made for the
          actual issuance of Common Stock or any payment of such consideration
          upon the exercise of any such options or rights or the conversion or
          exchange of such securities.

                     (C) Upon the termination or expiration of the
          convertibility or exercisability of any such Common Stock Equivalents,
          the Series B Conversion Price of the Series B Preferred Stock, to the
          extent in any way affected by or computed using such Common Stock
          Equivalents, shall be recomputed to reflect the issuance of only the
          number of shares of Common Stock (and Common Stock Equivalents which
          remain convertible or exercisable) actually issued upon the conversion
          or exercise of such Common Stock Equivalents.

Stock, if any, and/or the convertible promissory note dated as of January, 2000
by the Corporation in favor of EIS in the original principal amount of $12.015
million or (iii) effect a combination of (i) and (ii) above if applicable.

          6.   Other Distributions.  On or prior to the Conversion Termination
               -------------------
Date, in the event the Corporation shall declare a distribution payable in
securities of other persons, evidences of indebtedness issued by the Corporation
or other persons, assets (excluding cash dividends) or options or rights not
referred to in Section 4, then, in each such case for the purpose of this
Section 6, the holders of the Series B Preferred Stock shall be entitled to a
proportionate share of any such distribution as though they were the holders of
the number of shares of Common Stock of the Corporation into which their shares
of Series B Preferred Stock would be convertible as of the record date fixed for
the determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

          7.   Recapitalizations.  On or prior to the Conversion Termination
               -----------------
Date, if at any time or from time to time there shall be a recapitalization of
the Common Stock (other than a subdivision, combination or merger or sale of
assets provided for in Section 3 or Section 4 hereof) provision shall be made so
that the holders of the Series B Preferred Stock shall thereafter be entitled to
receive upon conversion of the Series B Preferred Stock the number of shares of
stock or other securities or property of the Corporation or otherwise, to which
a holder of Common Stock deliverable upon conversion would have been entitled on
such recapitalization. In any such case, appropriate adjustment shall be made in
the application of the provisions of Section 4 with respect to the rights of the
holders of the Series B Preferred Stock after the recapitalization to the end
that the provisions of Section 4 (including adjustment of the Series B
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series B Preferred Stock) shall be applicable after that event
as nearly equivalent as may be practicable.

          8.   No Impairment.  The Corporation will not, by amendment of its

<PAGE>

merger, dissolution, issuance or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
to be observed or performed hereunder by the Corporation, but will at all times
in good faith assist in the carrying out of all the provisions hereof and in the
taking of all such action as may be necessary or appropriate in order to protect
the Series B Conversion Rights and Exchange Right of the holders of the Series B
Preferred Stock against impairment.

     9.   No Fractional Shares and Certificate as to Adjustments. (a)    No
          ------------------------------------------------------
fractional shares shall be issued upon the conversion of any share or shares of
the Series B Preferred Stock, and the number of shares of Common Stock to be
issued shall be rounded to the nearest whole share.  Whether or not fractional
shares are issuable upon such conversion shall be determined on the basis of the
aggregate number of shares of Series B Preferred Stock each holder is at the
time converting into Common Stock and the aggregate number of shares of Common
Stock issuable to each such holder upon such conversion.

          (b)   Upon the occurrence of each adjustment or readjustment of the
Series B Conversion Price pursuant to Section 4, the Corporation, at its
expense, shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and prepare and furnish to each holder of shares of Series
B Preferred Stock a certificate setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.  The Corporation shall, upon the written request at any time of any
holder of Series B Preferred Stock, furnish or cause to be furnished to such
holder a like certificate setting forth (i) such adjustment and readjustment,
(ii) the Series B Conversion Price at the time in effect, and (iii) the number
of shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of a share of Series B Preferred
Stock.

          ---------------------------------------------
at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series B Preferred Stock, such number of its shares of Common
Stock that shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series B Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock not otherwise reserved
for issuance shall not be sufficient to effect the conversion of all then
outstanding shares of the Series B Preferred Stock, in addition to such other
remedies as shall be available to the holders of such Series B Preferred Stock,
the Corporation will take such corporate action that may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes,
including without limitation, engaging in best efforts to obtain the requisite
shareholder approval of any necessary amendment to its Certificate of
Incorporation.

     11.  Notices.  Any notice required by the provisions hereof to be given to
          -------
the holders of shares of Series B Preferred Stock shall be deemed given on the

to whom notice is to be given, and addressed to each holder of record at his
address appearing on the books of the Corporation.

all of the amounts provided to be funded as set forth in the Securities Purchase
Agreement, dated as of January 7th, 2000, between EIS and the Corporation, have
been funded or the Corporation has waived its right to any additional funding.

Stock in writing  setting forth (a) the terms of the redemption of the Series B
Preferred Stock, and (b) the proposed date for such redemption (the "Redemption
                                                                     ----------

not without first obtaining the approval (by vote or written consent, as
provided by law) of the holders of at least a majority of the then-outstanding
shares of Series B Preferred Stock, voting separately as a series:

          (a)   amend its Certificate of Incorporation so as to affect adversely
the shares of Series B Preferred Stock or any holder thereof (including by
creating any additional classes or series of preferred stock with a liquidation
preference or other rights senior to with the Series B Preferred Stock); or

          (b)  change the rights of the holders of the holders of the Series B
Preferred Stock in any other respect.

     15.  Status of Converted Stock.  In the event any shares of Series B
          -------------------------
Preferred Stock shall be converted pursuant to Section 4, the shares so
converted or exchanged shall be canceled and shall not be reissuable by the
Corporation.  The Certificate of Incorporation of the Corporation shall be

          below and as more specifically detailed in Schedule 1 ("Stage(s)"),
          provided that AVECIA shall, at all times during any Stage, have the
          flexibility to carry out the requirements of the Programme in such
          manner and at such times as AVECIA shall see fit and at its sole
          discretion and subject to the overall supervision of the JRC and the
          provisions of Clause 4.

          (a)  the identity of the first Product to be produced during Stage 4
               using the Process is confirmed;

          (b)  the analytical methods for the Products have been transferred
               from RPI to AVECIA; and

          (c)  the JRC confirms AVECIA's ability to manufacture the Product to
               be produced during Stage 4 using the Process.

     2.6  For the avoidance of doubt, any time periods specified in Schedule 1
          shall be indicative only unless provided for specifically in this
          Clause 2.

     2.7  AVECIA shall be responsible for obtaining all raw materials and
          reagents in order to produce the Product, including solvents, gases,
          amidites and other laboratory consumables and the solid support, to be
          utilised in conjunction with synthesis of a Product during the
          Programme.

     2.8  For the avoidance of doubt, it shall not be considered a breach of
          this Agreement by AVECIA if an objective of the Programme is not
          achieved:

          (a)  so long as AVECIA uses reasonable commercial and technical
               diligence and makes good faith efforts to perform its obligations
               to the fullest extent, and any failure to meet an objective of
               the Programme shall not relieve RPI of its obligations to make
               payment in accordance with Clause 3; or

          (b)  due to delay caused or contributed to by RPI.

3.   Payment for the Programme and First Kilogram of Product

          Programme and available for delivery to RPI by AVECIA (subject to a
          maximum of [ * ]for up to one kilogram of the Product manufactured
          during stage 4 of the Programme unless otherwise agreed under Clause
          5.3 below).

     For the avoidance of doubt, a gram of Product shall mean a gram of nucleic
     acid material which meets the Product Specification, net of any
     accompanying salts, water or other residual solvents.

4.   Reporting, Variation and Completion of the Programme
     ----------------------------------------------------

     4.1  The Programme and the progress by AVECIA under the Programme shall be
          supervised by the JRC which shall be established within the period of
          30 days following the date of this Agreement. Such supervision by the
          JRC shall take place in accordance with the provisions set out in
          Schedule 2.

     4.2  The parties may agree to alter the Programme either to extend the
          projected duration of any of the Stages or to change any of the work
          contained in any of the Stages provided that the parties shall first
          agree in writing the terms of such extension and alteration of the
          Programme including any amended payment terms.

     4.3  The parties shall conduct regular information exchange on at least two
          (2) weekly intervals by telephone or in a manner to be agreed by the
          JRC, provided that where AVECIA considers that, for the purposes of
          optimising or improving the Process, revisions or changes in methods
          should be undertaken by AVECIA during the performance of the
          Programme, AVECIA shall notify the JRC without delay of the reasons
          therefor and the actions which it proposes to take.

     4.4  Completion of the Programme will be deemed to have occurred when the
          quantity of Product specified in Stage 4 has been manufactured in
          accordance with the Product Specification and has been made available
          for delivery to RPI pursuant to Clause 5 below.

          the Programme any sums required to be paid pursuant to Clause 3 above
          which may remain outstanding at the completion of the Programme.
          Notwithstanding the foregoing, and subject to Clause 13, in respect of
          the Product held by AVECIA pursuant to Clause 5.1(a), RPI shall not be
          obligated to make any payments to AVECIA pursuant to Clause 3(b) prior
          to 1/st/ January 2001, unless RPI requests delivery of the Product
          prior to 1/st/ January 2001, in which case RPI shall make payments to
          AVECIA for the quantity of Product requested by RPI within 30 days of
          the date of the invoice for the Product.

5.   Delivery of First Kilogram of Product under Stage 4
     ---------------------------------------------------

     5.1(a)    Manufacture of the one kilogram (1kg) of the Product specified in
               Stage 4 shall take place on the date(s) agreed by the parties.
               AVECIA shall hold such manufactured Product in stock at its
               facilities and at its expense under the terms of the Quality
               Agreement, including the storage and stability instructions
               provided by RPI to AVECIA. Any Product so held by AVECIA shall be
               deemed to have been delivered and any risk shall immediately pass
               to RPI, except insofar as any damage occurs to the Product as a
               result of the negligence of AVECIA.

        (b)    Avecia shall use its best endeavours to deliver one kilogram
               (1kg) of Product as specified in Stage 4. However, if AVECIA
               shall manufacture at least [ * ] and up to [ * ], RPI shall be
               obliged to purchase all such Product from AVECIA during 2000
               subject to Clause 5.3 below. Subject to the foregoing, during
               2000 AVECIA shall deliver quantities of Product at RPI's request
               from time to time, such request not to be for less than 250 grams
               of Product.

     5.2       In the event that only a portion of the Product produced during
               Stage 4 is delivered to RPI, RPI shall be responsible only to pay
               for the quantity of the Product delivered.. If the quantity of
               the Product supplied by AVECIA is less than [ * ], then AVECIA
               agrees to synthesise sufficient Product in order to supply the
               shortfall quantity of Product to RPI, and the price for such
               shortfall quantity shall be no more than that paid by RPI for the
               initial delivered quantity. In the event that AVECIA then
               produces more than the 1 kilogram (1kg) of Product specified in
               Stage 4, the provisions of Clause 5.3 shall apply.

     5.3       In the event that AVECIA produces more than the 1 kilogram (1kg)
               of Product specified in Stage 4, RPI agrees to purchase such
               additional quantity up to a maximum of [ * ] at a price to be
               negotiated in good faith by the parties. Such agreed price shall
               be less than [ * ] per gram and shall be determined according to
               the yield and price matrix attached as Schedule 5 hereto. In the
               event that AVECIA produces more than [ * ] of the Product, RPI
               shall have an option, but not an obligation, to purchase such
               additional quantity of the Product at its sole discretion at a
               price per gram which does not exceed the price per gram paid for
               the additional [ * ] of the Product.

     5.4       Avecia will arrange for shipment and insurance of the Product
               produced during Stage 4 of the Programme to RPI as directed by
               RPI at RPI's cost and expense. The Products will be shipped and
               packaged by Avecia in accordance with RPI's shipping and
               packaging instructions as may be agreed from time to time.
               Deliveries will be made FOB Avecia's Grangemouth facility
               (Incoterms 2000) and will be shipped to RPI's address as set
               forth in this Agreement, or as otherwise directed by RPI in
               writing. Risk and title in respect of all Product

            this to RPI and the price for such completion quantity shall be no
            more, on a per gram basis, than that paid by RPI for the initial
            delivered quantity under that order. For the avoidance of doubt, if
            AVECIA delivers [ * ] of the amount of Product, RPI shall, subject
            to Clause 8, be obligated to pay AVECIA only for the [ * ] of the
            Product delivered.

       (b)  In the event that Avecia manufactures Product in quantities

            price to be negotiated in good faith by the parties in respect of
            the additional [ * ], according to the yield and price matrix
            attached as Schedule 5, but such amount shall not cost more per gram
            than for the said amount ordered In the event AVECIA produces more
            than [ * ] of the Product, RPI shall have an option, but no
            obligation, to purchase such additional quantity of the Product at
            its sole discretion at a price per gram not to exceed the price per
            gram paid for the additional quantity of the Product.

     7.6    Delay in Delivery.  In the event that the AVECIA delivers any
            -----------------
            Product later than four weeks from the date of delivery set out in
            the Delivery Schedule other than as a result of Force Majeure as set
            out in Clause 21, RPI shall be entitled to a five per cent reduction
            in the price of the Product delivered one month late and to an
            additional ten per cent reduction in price for each of the next two
            complete month's delay thereafter. In the event AVECIA is unable to
            deliver the Product within three months from the date set out in the
            Delivery Schedule, then RPI shall have the option to either
            terminate the Agreement pursuant to

                                     S-12

            Clause 13.3(b) or to manufacture or have manufactured by a Nominated
            Manufacturer the Product. In the event RPI chooses the latter
            option, then in order to satisfy RPI's requirement for that quantity
            of the Product ordered, AVECIA, subject to Clause 12, agrees (i) to
            make a good faith effort to provide, at no cost to RPI or to a
            Nominated Manufacturer, the technical information necessary for such
            manufacture of the Product; and (ii) to grant to RPI or a Nominated
            Manufacturer a personal, royalty free licence under AVECIA's
            relevant Intellectual Property to enable RPI or such Nominated
            Manufacturer to undertake the manufacture of the Product7.7 Invoices
                                                                        --------
            and Payment Terms. AVECIA shall issue an invoice at the price agreed
            -----------------
            under Clause 7.2, as adjusted pursuant to Clause 7.6 if relevant,
            above in respect of each shipment of the Product to RPI on despatch
            by AVECIA of the Product for delivery to RPI. RPI shall pay all such
            invoices in full within thirty days from the date of invoice,
            provided that RPI shall not have rejected such delivery of Product
            under Clause 8.1. In the event that payment is made by RPI before
            any Product is examined by RPI pursuant to Clause 8.2, AVECIA will
            reimburse RPI for the price of such Product if it is found that the
            Product does not meet the Product Specification.

     7.8    Responsibility for Raw Materials.  AVECIA shall be responsible for
            --------------------------------
            obtaining all raw materials and reagents in order to produce the
            Product, including solvents, gases, amidites and other laboratory
            consumables and the solid support, to be utilised in conjunction
            with synthesis of a Product.

     7.9    Third Party Price Notice.  After a period of [ * ] from signature
            ------------------------
            of this Agreement, RPI shall be entitled to give AVECIA written
            notice if a third party under a supply agreement with RPI of at
            least three years duration is able to supply identical products in
            identical volumes to RPI at a price which is at least ten per cent
            lower than the price for the Products agreed under Clause 7.2 above
            ("Third Party Price Notice"). RPI and AVECIA shall meet to discuss
            the position and if agreement on price is not reached within 30 days
            of receipt of such Third Party Notice, then RPI may purchase the
            quantity so offered from the third party and the amounts of such
            Products purchased shall be construed as falling within the amounts
            of Products to be delivered according to the Product Minimum
            referred to in Clause 7.1. RPI shall not be obliged to divulge the
            identity of such third party, but at the request of AVECIA shall in
            lieu provide satisfactory evidence, signed by an independent notary
            public certifying the genuineness of the competitive offer.

            or Intellectual Property arising as a result of this Agreement under
            Clause 6.2(b) above) or Confidential Information acquired under this

8.   Quality of the Product
     ----------------------

     8.1  The Product manufactured and delivered by AVECIA to RPI under Clause 7
          above shall conform to the Product Specification for such Product.

     8.2  RPI shall examine all Product delivered to it pursuant to this
          Agreement in accordance with the methods of analysis set out in the
          Quality Agreement for such Product. RPI shall notify AVECIA of any
          failure of the Product to meet the Product Specification within [ * ]
          days of receipt of the relevant Product. RPI shall be entitled to
          reject any Product which does not meet the Product Specification
          ("Rejected Product")

     8.3  (a)  RPI will return any Rejected Product to AVECIA and, if AVECIA
               agrees with RPI's notification of failure, AVECIA shall replace
               the Rejected Product at no additional cost to RPI within [ * ]
               days of receiving notice from RPI under Clause 8.2 or on a new
               delivery date as mutually agreed to in writing by the Parties.

          (b)  In the event AVECIA is unable to replace the Rejected Product
               within such time, RPI shall be entitled to exercise its Standby
               Rights (as set out in Clause 9.1 below) to enable RPI or a
               Nominated Manufacturer to manufacture sufficient Product to
               replace the Rejected Product, and AVECIA, subject to Clause 12,
               agrees to make a good faith effort to provide, at no cost to RPI
               or to a Nominated Manufacturer, the technical information
               necessary for such manufacture of the Product. In addition,
               AVECIA will reimburse to RPI that element of the reasonable cost
               of the Product manufactured by the Nominated Manufacturer which
               is in excess of the price which RPI would have had to pay to
               AVECIA. The amounts of such Products manufactured by the
               Nominated Manufacturer shall be construed as falling within the
               amounts of Product to be purchased by RPI in accordance with the
               Product Minimum in Clause 7.1 above.

          (c)  If AVECIA disagrees with RPI's notification of failure the JRC
               shall consider the matter and in the event no agreement is then
               reached, the parties shall jointly appoint an expert to determine
               whether the Product is a Rejected Product, and the costs and fees
               of the expert shall be borne by the losing party.  During the
               period of dispute resolution under this Clause 8.3(c):-

               (i)  If RPI requests AVECIA to resynthesise the quantity of the
                    Rejected Product, AVECIA shall in good faith resynthesise
                    the

                                     S-14
<PAGE>

                      Product and deliver it to RPI within [ * ] of receiving
                      such a request from RPI. Subject to Clause 8, RPI will
                      make payment for the resynthesised quantity within [ * ]
                      of delivery. If the dispute is resolved in favour of
                      AVECIA, RPI agrees to purchase from AVECIA both batches of
                      the Product, and such additional quantity of the Product
                      resynthesised by AVECIA shall not count towards the
                      Product Minimum. If the dispute is resolved in favour of
                      RPI, RPI will make payment only for the resynthesised
                      Product.

               (ii)   In the event AVECIA is unable to replace the Rejected
                      Product within the time stated in Clause 8.3(c)(i) above,
                      RPI shall be entitled to exercise its Standby Rights (as
                      set out in Clause 9.1 below) to enable RPI or a Nominated
                      Manufacturer to manufacture sufficient Product to replace
                      the Rejected Product, and AVECIA, subject to Clause 12,
                      agrees (i) to make a good faith effort to provide to RPI
                      or to a Nominated Manufacturer, at RPI's cost, the
                      technical information necessary for such manufacture of
                      the Product; and (ii) to grant to RPI or a Nominated
                      Manufacturer a personal, royalty free licence under
                      AVECIA's relevant Intellectual Property to enable RPI or
                      such Nominated Manufacturer to undertake such manufacture.
                      If the dispute is resolved in favour of AVECIA, RPI agrees
                      to purchase from AVECIA the entire amount of the Product
                      in dispute and to make immediate payment, and any
                      additional quantity of the Product manufactured by RPI or
                      its Nominated Manufacturer shall not count toward the
                      Product Minimum. If the dispute is resolved in favour of
                      RPI, AVECIA will reimburse to RPI that element of the
                      reasonable cost of the Product manufactured by the
                      Nominated Manufacturer which is in excess of the price
                      which RPI would have had to pay to AVECIA, together with
                      any costs paid by RPI in respect of the transfer of the
                      technical information by AVECIA, and the originally
                      ordered quantity of the Product shall be construed as
                      falling within the amount of Product to be purchased by
                      RPI in accordance with the Product Minimum.

               (iii)  If RPI does not request AVECIA to resynthesise the
                      Rejected Product, then AVECIA shall not be required to
                      start the resynthesis until the dispute is resolved or
                      until RPI make such a request, whichever is the sooner.
                      For the avoidance of doubt, no act or omission of RPI
                      under this Sub-clause 8.3(c)(iii) shall cause the Product
                      Minimum to be reduced by the amount of the Rejected
                      Product.

     8.4  In the absence of notification that the Product does not meet the
          Product Specification within the period set out in Clause 8.1 above,
          the relevant consignment of the Product shall be deemed to have been
          accepted by RPI in full compliance with the Product Specification.


9.   Licence under AVECIA Intellectual Property to Manufacture the Product
     ---------------------------------------------------------------------

     9.1  If AVECIA is unable to meet the delivery requirements set out in the
          Delivery Schedule agreed under Clause 7.3 above, then subject to
          Clause 12, AVECIA shall grant to RPI or a Nominated Manufacturer a
          personal licence on reasonable commercial terms under AVECIA's
          relevant Intellectual Property to enable RPI or such Nominated
          Manufacturer to undertake the manufacture of Products, in order to
          satisfy its requirements for Products ("Standby Rights").  In the
          event that RPI wishes to exercise its Standby Rights, RPI will provide
          Avecia with written notice thereof in advance of such exercise and,
          subject to Clause 8,  the volume of products manufactured under the
          Standby Rights will be subtracted from the Product Minimum.

     9.2  Manufacture of Products in excess of Product Minimum. In the event
          ----------------------------------------------------
          that RPI's requirements for delivery of the Product over the period
          from 1/st/ January 2000 to 31/st/ December 2002, as set out in the
          Delivery Schedule, are in excess of the Product Minimum, then provided
          that RPI shall purchase the greater of the Product Minimum or [ * ] of
          its total requirements for delivery of the Product from AVECIA, RPI
          shall have the ability to exercise its Standby Rights for manufacture
          of the balance of the Product required during such period. AVECIA, at
          its cost, shall have the right to have an independent third party
          certify RPI's delivery requirements each twelve months within the
          above said period, subject to Clause 12.

     9.3  Any royalty payable under the licence granted as a result of the
          exercise of the Standby Rights shall be dependent upon the volume of
          Products to be manufactured by AVECIA on behalf of RPI and shall not
          exceed [ * ]of the selling price of Products made by such a Nominated
          Manufacturer. Neither RPI nor the Nominated Manufacturer, shall be
          obligated to make any payments to AVECIA for the exercise of Standby
          Rights pursuant to Clause 7.6 or pursuant to Clause 8.3 unless the
          dispute is resolved in AVECIA's favour.

     9.4  Without prejudice to Clause 13.5, upon the expiry or termination of
          this Agreement, RPI may request a licence under AVECIA's Intellectual
          Property, and the parties will negotiate in good faith the commercial
          terms of such royalty bearing licence.

10.  Quality Agreements
     ------------------

     AVECIA and RPI shall enter into a quality agreement in respect of each
     Product on a case by case basis, the terms of which shall be agreed by the

                      assistance as it shall reasonably require in respect of
                      the conduct of such defence.

     11.2  Liability for the Products. Liability in respect of any Product
           --------------------------
           delivered to RPI and not rejected by RPI within the period set out in

           Property arising from the Programme and in the possession of a party
           shall be treated as having been disclosed to that party by the party
           owning such Intellectual Property pursuant to Clause 6.2 above, and
           the expressions "Disclosing Party" and "Receiving Party" shall be
           construed accordingly.

     12.2  The foregoing restrictions on the Receiving Party shall not apply to
           any Confidential Information which:

           (a)  the Receiving Party can prove was already in its possession and

           (c)  is or becomes available to the public whether in printed
                publications or otherwise through no act or default on the part
                of the Receiving Party or its agents or employees; or

           (d)  the Receiving Party can prove to the reasonable satisfaction of
                the Disclosing Party has been developed independently of the

                reference to any of the Confidential Information disclosed by
                the Disclosing Party.

     12.3  In order to secure the obligations set out in this Clause 12 the
           Receiving Party agrees to exercise every reasonable precaution to
           prevent and restrain the unauthorised disclosure and use of
           information subject to confidentiality, including restricting access
           to such information to such of its employees as are bound to keep
           such information confidential and need to have such access for the
           purpose of this Agreement.

           Permitted Recipient to which Confidential Information is to be
           disclosed is made aware of the obligations contained in this
           Agreement and enters into confidentiality obligations in
           substantially the same terms as those contained in this Agreement
           directly with the Disclosing Party.

     12.5  The provisions of this Clause 12 shall survive termination or expiry
           of this Agreement and shall continue for a period of 10 years from
           the date of that termination or expiry.

     12.6  The parties shall remain bound by the obligations in the Mutual
           Confidentiality Agreement signed by them and dated 23/rd/ December
           1998, but in the event of any conflict between the terms of that
           Mutual Confidentiality Agreement and the terms of this Agreement, the
           latter shall prevail.

1.                             PROJECT OBJECTIVE

This proposal describes technology transfer, process development, process scale
up and manufacture of 1 kg of mutually agreed product.

The data generated from the technology transfer and scale up program is meant to
provide a degree of assurance that the process detailed in the Batch
Manufacturing Instructions will produce product suitable for use in clinical
trials.

The sequence of the oligonucleotide is described below.


2.                             PROJECT SCOPE

The project will consist of five stages:

*  Technology Transfer of Process and Analytical Methods
*  Process Development - Deprotection and Purification scale up of the ribozyme
*  products as determined by the JRC
*  Preparation of GMP Manufacture Documentation
*  Process Scale Up - GMP Manufacture of Kilo 1 of a mutually agreed product


Prior to the start of the project and bi-weekly following initiation, a joint
review committee(JRC) composed of members from RPI and Avecia LSM will meet.   A
full review of all work completed will be presented, the project plan and
specifications reviewed, and project progression agreed.

Throughout the project any changes made to the work detailed in the proposal
will be jointly agreed with RPI, managed and documented in accordance with
Avecia LSM's project management procedures.

Stability studies are not currently within the scope of this project.  If
required they will be the subject of a separate quotation.


3.                           MOLECULE DESCRIPTION:

The oligonucleotide product is classified as Active Pharmaceutical Ingredient
"Ribozyme Sequence in Here"
Provisional Specifications listed in Appendix 2.


4.                               PROJECT PLAN

4.1          TECHNOLOGY TRANSFER OF PROCESS AND ANALYTICAL METHODS

RPI has generated experience in the manufacture of ribozymes and it is
recognised that this knowledge must be transferred to Avecia LSM manufacturing
personnel in order for the supply of products to commence.  A Technology
transfer plan/agreement will be agreed.  This document will detail the
activities, information requirement, success criteria and timetable for
technology transfer of the manufacturing process and the analytical methods.

It is anticipated that RPI will provide Avecia with the following information:
*  Raw material suppliers, specifications and testing procedures
*  RPI and [ * ] Process description and process equipment specifications
*  Details of in-process tests and specifications
*  Toxicological information on the oligonucleotide
*  Analytical Methods(final product and intermediates) and supporting
   documentation(reagent requirements, equipment etc.)
*  Reference samples

                                      S-3
<PAGE>

The Technology Transfer project will be conducted in four phases:
*  Information transfer and definition of Initial process
*  Analytical methods technical transfer at Avecia LSM
*  Oligo Pilot II production of development material at Avecia LSM, utilising
   RPI's current process parameters
*  Technical clearance to manufacture

4.2            PROCESS DEVELOPMENT - DEPROTECTION AND PURIFICATION
               SCALE UP OF THE PRODUCTS AS DETERMINED BY THE JRC.
Deprotection

The aim of this stage is to evaluate the deprotection process and provide a
recommended route for the large scale GMP manufacture in the form of a Process
Description.

The Deprotection process development will start with a full review and analysis
of samples and records generated during the technology transfer stage.
Conditions will be defined which provide material of the appropriate purity in a
reproducible manner.

During large scale manufacture there will be opportunities to further
investigate the cleavage mixture, time course and reaction temperature.



Purification


The aim of this stage is to evaluate the purification process and provide a
recommended route for the large scale GMP manufacture in the form of a Process
Description.

The Purification process development will start with a full review and analysis
of samples and records generated during the technology transfer stage.
Procedures to ensure consistent column loading will be defined.  Chromatography
gradient and flow rate will be further investigated.

Samples obtained from the OPII production runs at Avecia LSM  will be utilised
to gain full understanding of the purification parameters.  The material will be
loaded on small scale Biotage rig, with a view of extrapolating the data to the
large scale Biotage rig in the Grangemouth Pharmaceutical Manufacturing
Facility.

These investigations will have the following objectives:
*  Define procedures to ensure consistent column loading
*  Investigate the impact of variation in column gradient and flow rate
*  investigate impact of increased column loading, with a view to increasing
   throughput

- --------------------------------------------------------------------------------

4.4   PROCESS SCALE UP - GMP MANUFACTURE OF KILO 1 MUTUALLY AGREED PRODUCT.

Avecia LSM will carry out the GMP manufacture of mutually agreed Product at the
range of [ * ] on the Oligo Process.  The objective of the scale up program
is to demonstrate the process described in the process description produces
material of the required quality and specification.

Avecia LSM will manufacture the scale up batches to the agreed specification
using the Process instructions, material generated from this stage will be
suitable for use in toxicology and human clinical trials.

Avecia LSM will manufacture 1kg oligonucleotide to the agreed specification
following the Process Instructions and documented analytical methods.

The manufacture program following oligonucleotide assembly will proceed only if
there is agreement by the joint review committee that the process for
deprotection and purification, as detailed in the process instructions, can
operate efficiently at scales above [ * ].  If it is deemed that this
process is insufficient to produce the quality and quantity of oligonucleotide
product RPI require, than the decision will be made to continue scale up
development work.

Note: Further development may be required in the GMP phase, this work will be
documented and all changes subject to QA approval.

The Oligonucleotide will be supplied in a form agreed upon by both parties.

A Certificate of Analysis will be supplied.

Avecia LSM will retain a sample of product (exact amount to be agreed) for use
as retention material and in further analytical studies.

1    INTRODUCTION


     This plan details the mechanism by which the RPI Angiozyme process will be
     technology transferred between RPI and LifeScience Molecules Grangemouth
     Works and sets out the activities, information required and timetable in
     order to successfully complete the technology transfer exercise.

     A well managed technology transfer is key to the establishment of a
     manufacturing process which is consistent in operation and generates
     Angiozyme of equivalent quality to that manufactured by RPI.

     Material provided by LSM in Grangemouth will be used in a process
     registered in the United States and the rest of the world. As such:
     technology transfer, commissioning, validation and change control must be
     undertaken to ensure that material produced in the Campaign is equivalent
     to material produced by RPI for submissions to the FDA.

     The material produced by this manufacture will be used for: Phase ()
     Clinical Trials

     Technology transfer will be conducted in three phases:


     Initiation:        Identification of responsible personnel
                        agreement on information to be transferred (protocol)
                        transfer of information


     Commissioning:     Pre manufacture Technical Transfer review
                        Initial manufacture


     Note: The pre manufacturing technical transfer review must include
     agreement of and actions to minimise the risks that may result from the
     differences between the facilities at RPI and that at Grangemouth

     Completion:        Post manufacturing review of success of technology
                        transfer Sign -off of Technology transfer protocol

     A flow chart outlining the process is attached as Appendix I

     It is intended that sign-off will take place following the initial
     campaign, subject to successfully meeting the required standards and
     criteria.


2    AIMS


     The purpose of technology transfer is to supply technical expertise and
     associated information to enable Avecia Life Science Molecules, Grangemouth
     facility, to successfully undertake manufacture of RPI Angiozyme in light
     of the fact that the LSM and RPI facilities are not identical.


     The agreed timetable is detailed in Appendix II.


     The critical success factors for successful transfer are as follows:

     .  Avecia Life Science Molecules, Grangemouth Works will manufacture an
        initial quantity of Angiozyme  by the end of [   *.   ]  Future
        manufacture may be carried out following the initial Campaign.


     .  The Grangemouth Works manufacturing process will be specified by the
        current RPI process.  Processing will be carried out within the scope
        of the pre-determined parameters.


     .  An established change control mechanism should be used for any changes.


                                     S-24
<PAGE>

     .  The quality of the Angiozyme supplied by Avecia Life Science Molecules
        Grangemouth Works must be within specification and typical of
        manufacture from RPI.

     .  Technology transfer, plant operation, processing and cleaning will be
        carried out to Grangemouth Works Quality standards.

3    INITIATION

     5.1 DOCUMENTATION


     The Technology transfer managers on each site will be formally responsible
     for ensuring document issue and control.

     All documents must be numbered and where appropriate version controlled

     The transfer of all documents will must be done within a change control
     system

                                     S-25
<PAGE>

     A copy of all documents outlined in Appendices III and IV (information
     required before commissioning) and Appendix V (information required before
     technology transfer completion) must be supplied via the QA
     representatives. This data will form the basis of the respective sites
     technology transfer documentation.

     5.2 REVIEWS

     Meetings should be held between functional nominees as appropriate to
     ensure complete transfer of information and progress on actions.

     A formal pre-commissioning review will take place to ensure information
     transfer is complete and that all relevant information has been
     incorporated into Grangemouth Works systems.

     Performance of the initial manufacture should be reviewed and documented as
     early as possible after the campaign.

     Following completion of the Campaign a technology transfer review will be
     held prior to sign-off to ensure documentation is complete and
     satisfactory.

6    INFORMATION TRANSFER

     control.

     During Technology Transfer the starting point for Change Control will be
     defined as the information supplied by RPI to define the technology.

     Amendments to the RPI technology should be covered by the Grangemouth Works
     change control procedure and should not be adopted without prior
     authorisation from RPI.

8    TECHNOLOGY TRANSFER COMPLETION

     On completion of Technology Transfer responsibility will pass to
     Grangemouth Works to control change independently.

     Elements that cannot be changed without prior authorisation should be
     identified as part of the technology transfer completion review.

8.2  TECHNOLOGY TRANSFER REVIEW AND SIGN-OFF

      Following the initial manufacturing campaign there will be a review to
      define whether the critical success factors listed in 8.1 have been met.

      The review will comprise the preparation and approval of documents
      (appendix V) and a meeting to agree a list of any outstanding actions.

      In the event of Grangemouth Works conducting a second or subsequent
      campaign of Angiozyme  prior to sign-off of technology transfer a written
      plan will be agreed between RPI and Grangemouth Works covering outstanding
      issues.

      After a final review to confirm that technology transfer has been
      successfully concluded then the Technology Transfer Completion Document
      will be issued for authorisation.

      Completion is targeted for end of November 2000.

8.3  POST TECHNOLOGY TRANSFER

      As part of technology transfer sign off a plan will be agreed in the event
      of any future manufacturing campaigns. Routes of communications between
      the two sites will be clearly identified emphasising the need for
      continuity. A technical manager will be nominated from each site to act as
      first line contacts for transfer of information.
