ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "Securities Act"). The Registrant's Bylaws also
provide that the Registrant will indemnify its directors and executive officers
and may indemnify its other officers, employees and other agents to the fullest
extent not prohibited by Delaware law.
 
     The Registrant's Certificate of Incorporation provides for the elimination
of liability for monetary damages for breach of the directors' fiduciary duty of
care to the Registrant and its stockholders. These provisions do not eliminate
the directors' duty of care and, in appropriate circumstances, equitable
remedies such as injunctive or other forms of non-monetary relief will remain
available under Delaware law. In addition, each director will continue to be
subject to liability for breach of the director's duty of loyalty to the
Registrant, for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for any transaction from which the
director derived an improper personal benefit, and for payment of dividends or
approval of stock repurchases or redemptions that are unlawful under Delaware
law. The provision does not affect a director's responsibilities under any other
laws, such as the federal securities laws or state or federal environmental
laws.
 
     The Registrant has entered into agreements with its directors and executive
officers that require the Registrant to indemnify such persons against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
(including expenses of a derivative action) in connection with any proceeding,
whether actual or threatened, to which any such person may be made a party by
reason of the fact that such person is or was a director or officer of the
Registrant or any of its affiliated enterprises, provided such person acted in
good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the Registrant and, with respect to any
criminal proceeding, had no reasonable cause to believe his or her conduct was
unlawful. The indemnification agreements also set forth certain procedures that
will apply in the event of a claim for indemnification thereunder.

     The Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Registrant and
its officers and directors for certain liabilities arising under the Securities
Act or otherwise.
 
     The Registrant intends to purchase a general liability insurance policy
which covers certain liabilities of directors and officers of the Registrant
arising out of claims based on acts or omissions in their capacity as directors
or officers.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
     Since its inception in February 1995, the Registrant has sold and issued
the following unregistered securities:
 
          (1) In February 1995, the Registrant sold and issued an aggregate of
     7,500,000 shares of Series A Preferred Stock to two accredited investors
     for cash in the aggregate amount of $2,500,000 and the assignment of
     certain intellectual property rights.
 
          (2) In August 1995, the Registrant sold and issued an aggregate of
     2,333,333 shares of Series B Preferred Stock to six accredited investors
     for cash in the aggregate amount of $3,500,000.
 
          (3) In March 1996, the Registrant sold and issued 1,200,000 shares of
     Common Stock to one accredited investor in exchange for a promissory note
     in the amount of $180,000.
 
          (4) In April 1996, the Registrant sold and issued an aggregate of
     9,964,607 shares of Series C Preferred Stock and Warrants to purchase
     1,496,182 shares of Common Stock to a group of accredited investors for
     $22,420,363.74.
 
          (5) From March 1995 to December 6, 1996, the Registrant granted
     incentive stock options and nonstatutory stock options to employees,
     directors and consultants covering an aggregate of 2,362,803 shares of the
     Registrant's Common Stock, at a weighted average exercise price of $.36 per
     share. As of December 6, 1996, the Registrant has sold 112,038 shares of
     its Common Stock to employees, directors and consultants pursuant to
     exercise of stock options.
 
          (6) In December 1996, the Registrant issued a warrant to purchase
     74,000 shares of Common Stock to one accredited investor in connection with
     an equipment lease financing.
 
     The share amounts set forth above do not take into account the
one-for-three reverse stock split that will be effected prior to the closing of
this offering.
 
     The sale and issuance of securities in the transactions described in
paragraphs (1), (2), (4) and (6) above were deemed to be exempt from
registration under the Securities Act by virtue of Section 4(2) adopted
thereunder. The purchasers in each case represented their intention to acquire
the securities for investment only and not with a view to distribution thereof.
Appropriate legends are affixed to the stock certificates or warrants issued in
such transactions. All recipients either received adequate information about the
Registrant or had access, through employment or other relationships, to such
information.
 
     The sale and issuance of securities in the transactions described in
paragraph (3) and (5) above were deemed to be exempt from registration under the
Securities Act by virtue of Rule 701 promulgated thereunder, in that they were
issued either pursuant to written compensatory benefit plans or pursuant to a
written contract relating to compensation, as provided by Rule 701.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide the Underwriters at
the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 14 or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that: (1) for purposes of
determining any liability under the Securities Act, the information omitted from
the form of prospectus as filed as part of the registration statement in
reliance upon Rule 430A and contained in the form of prospectus filed by the
Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of the registration statement as of the time it was
declared effective, and (2) for the purpose of determining any liability under
the Securities Act, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and this offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

                  (GMP) will mean Good Manufacturing Practices and General
                  Biological Products Standards as promulgated under the US
                  Federal Food and Drug and Cosmetic Act at 21CFR, (chapters

                  re-enacted from time to time. Lonza's operational quality
                  standards are defined in internal GMP policy documents and are
                  based on Lonza's interpretation of the GMP legislation for
                  bulk clinical grade Biologicals. Additional product-specific
                  development, documentation and validation work may be required
                  to support regulatory applications to conduct clinical trials,
                  or market a product.

                  (GLP) will mean practices as recommended in the guidelines of
                  the UK Compliance Programme.

         Always provided Lonza's ability to perform the Services is not
         prejudiced thereby, the Customer's authorised representative may have
         access at times to be reasonably agreed to the banks containing the
         Cell Line at Lonza's premises and may remove all or part of said cell
         banks, as required.

3.       Technology Transfer

         At the Customer's request, Lonza agrees to enter into good faith
         negotiations for the grant of a non-exclusive licence to the Customer
         on commercially reasonable terms to manufacture Product under certain
         Patent Rights and Lonza Know-How. Such grant shall be subject to
         agreement on applicable terms and conditions and shall apply only to

         Stage 5) and only to the extent Lonza is able to grant a licence
         thereto at the time of signature of such agreement.

         may be the subject of any such licence grant shall be limited to the
         Patent Rights and Lonza Know-How used by Lonza in the operation of the
         Process for production of Product to GMP (Schedule 2 Stage 5) and

                  3.3.2    not part with possession of the Cell Line or the
                           Product, save for the purpose of tests at the Testing
                           Laboratories; and

                  3.3.3    procure that all Testing Laboratories are subject to
                           obligations of confidence substantially in the form
                           of those obligations of confidence imposed on Lonza
                           under these Standard Terms.

         3.4      Lonza shall not be liable for any loss, damages, costs or
                  expenses of any nature, whether direct or consequential,
                  occasioned by the carrying out (in whole or in part) of tests
                  or the failure to carry out tests by Testing Laboratories (A
                  "Testing Laboratory Breach"). Lonza agrees to use commercially
                  reasonable efforts to enforce any rights Lonza may have
                  against a Testing Laboratory in the event that either Lonza or
                  the Customer supers any loss, damage, costs or expenses of any
                  nature occasioned by a Testing Laboratory Breach. In the event
                  Lonza recovers damages against a Testing Laboratory Lonza
                  shall pay to the Customer after deduction of any out-of-pocket
                  legal expenses such proportion of the amount of damages as the
                  parties shall agree and such agreement shall take account of
                  the loss suffered by both Lonza and the Customer.

         3.5      The Customer warrants to Lonza that:

                  3.5.1    the Customer is and shall at all times throughout the
                           duration of the Agreement remain entitled to supply
                           the Cell Line and Customer Information to Lonza; and

                                      30.
<PAGE>   31

                  3.5.2    the use by Lonza of the Cell Line and the Customer
                           Information in accordance with this Agreement will
                           not infringe any rights (including, without
                           limitation, any intellectual or industrial property
                           rights) vested in any third party.

                  Lonza warrants that as of the date of this Agreement Lonza's
                  legal or corporate departments have not received notice of nor
                  are aware of any claim or demand and Lonza is not party to any
                  court proceedings in which a third party is claiming
                  infringement of its intellectual property rights by Lonza's
                  use of the Process and Lonza agrees to notify the Customer at
                  any time during the term of this Agreement if it receives any
                  such notice or demand and of the steps it intends to take as a
                  result of such notice or demand.

         3.6      The Customer undertakes to indemnify and to maintain Lonza
                  promptly indemnified against any loss, damages, costs and
                  expenses of any nature (including court costs and legal fees
                  on a full indemnity basis), whether direct or consequential,
                  and whether or not foreseeable or in the contemplation of
                  Lonza or the Customer, that Lonza may suffer arising out of or
                  incidental to any breach of the warranties given by the
                  Customer under Clause 3.5 above.

         3.7      The obligations of the Customer and Lonza under Clauses 3.3,
                  and 3.6 shall survive the termination for whatever reason of
                  the Agreement.

4.       Provision of the Services

         4.1      Lonza shall carry out the Services as provided in Schedule 2.

         4.2      The timescales set down for the performance of the Services
                  (including without limitation the dates for production and
                  delivery of Product) and the quantities of Product for
                  delivery set out in Schedule 2 are estimated only.

         4.3      The Customer shall not be entitled to cancel any unfulfilled
                  part of the Services or to refuses to accept the Services on
                  grounds of late performance, late delivery or failure to
                  produce the estimated quantities of Product for delivery.
                  Lonza shall not be liable for any loss, damage, costs or
                  expenses of any nature, whether direct or consequential,
                  occasioned by:

                  4.3.1    any delay in performance or delivery howsoever
                           caused; or

                  4.3.2    any failure to produce the estimated quantities of
                           Product for delivery.

                                      31.
<PAGE>   32

         4.4      Lonza shall comply with all statutory, regulatory and similar
                  legislative requirements from time to time applicable to the
                  Services under the laws of European Union, United Kingdom and
                  USA. If the Customer requests Lonza to comply with any other
                  statutory, regulatory or similar legislative requirements (the
                  Foreign Requirements") Lonza shall use reasonable commercial
                  endeavours to do so provided that:

                  4.4.1    the Customer shall be responsible for informing Lonza
                           in writing of the precise Foreign Requirements which
                           the Customer is requesting Lonza to observe;

                  4.4.2    such Foreign Requirements do not conflict with any
                           mandatory requirements under the laws of England;

                  4.4.3    Lonza shall be under no obligation to ensure that
                           such written information complies with the applicable
                           Foreign Requirements; and

                  4.4.4    all costs and expenses incurred by Lonza in complying
                           with such Foreign Requirements shall be charged to
                           the Customer in addition to the Price.

         4.5      Delivery of Product shall be ex-works. Risk in and title to
                  Product shall pass on delivery. Transportation of Product,
                  whether or not under any arrangements made by Lonza on behalf
                  of the Customer, shall be made at the sole risk and expense of
                  the Customer.

         4.6      Unless otherwise agreed Lonza shall package and label Product
                  for delivery ex-works. It shall be the responsibility of the
                  Customer to inform Lonza in writing in advance of any special
                  packaging and labelling requirements for Product. All
                  reasonable additional costs and expenses of whatever nature
                  incurred by Lonza in complying with such special requirements
                  shall be charged to the Customer in addition to the Price.

5.       Transportation of Product and Customer Tests

         5.1      If requested by the Customer, Lonza will (acting as agent of
                  the Customer for such purpose) arrange the transportation of
                  Product from Lonza's premises to the destination indicated by
                  the Customer together with insurance cover for Product in
                  transit at its invoiced value. All additional costs and
                  expenses of whatever nature incurred by Lonza in arranging
                  such transportation and insurance shall be charged to the
                  Customer in addition to the Price.


                                      32.
<PAGE>   33

         5.2      Where Lonza has made arrangements for the transportation of
                  Product, the Customer or its designee shall diligently examine
                  the Product as soon as practicable after receipt. Notice of
                  all claims (time being of the essence) arising out of:

                  5.2.1    damage to or total or partial loss of Product in
                           transit shall be given in writing to Lonza and the
                           carrier within three (3) days of delivery; or

                  5.2.2    non-delivery shall be given in writing to Lonza
                           within ten (10) days after the date of Lonza's
                           despatch notice.

         5.3      The Customer shall make damaged Product available for
                  inspection and shall comply with the requirements of any
                  insurance policy covering the Product notified by Lonza to the
                  Customer. Lonza shall offer the Customer all reasonable
                  assistance (at the cost and expense of the Customer) in
                  pursuing any claims arising out of the transportation of
                  Product. At any time, if requested by the Customer, Lonza
                  shall supply the Customer with Product samples retained by
                  Lonza prior to shipment of Product for use by the Customer in
                  confirming whether Product meets the Specification (always
                  provided that such supply of Product samples does not
                  prejudice Lonza's ability to meet GMP or regulatory
                  requirements regarding retention of Product samples).

         5.4      Immediately upon receipt of Product or Product samples, the
                  Customer or its appointed agent shall carry out the Customer
                  Tests. If the Customer Tests show that the Product fails to
                  meet Specification, the Customer shall give Lonza written
                  notice thereof within sixty (60) days from the date of
                  delivery of the Product ex-works, and shall return such
                  Product to Lonza's premises for further testing. In the
                  absence of such written notice Product shall be deemed to have
                  been accepted by the Customer as meeting Specification. If
                  Lonza is satisfied that Product returned to Lonza fails to
                  meet Specification and that such failure is not due (in whole
                  or in pan) to acts, or omissions of the Customer or any third
                  party after delivery, of such Product ex-works, Lonza shall in
                  its sole discretion refund that part of the Price that relates
                  to the production of such Product or replace such Product at
                  its own cost and expense. Notwithstanding the foregoing, if
                  the Customer determines following acceptance of the Product
                  from Lonza that the Product has been adulterated within the
                  meaning of the United States Federal Food, Drug and Cosmetic
                  Act by Lonza, then, subject to the Customer providing Lonza
                  evidence of its determination and samples of adulterated
                  Product and subject to Lonza's right to dispute such


                                      33.
<PAGE>   34

                  determination in accordance with Clause 5.5, Lonza shall in
                  its sole discretion refund that part of the Price that relates
                  to the production of such Product or replace such Product at
                  its own cost and expense.

         5.5      If there is any dispute concerning whether Product returned to
                  Lonza fails to meet Specification or whether such failure is
                  due (in whole or in part) to acts or omissions of the
                  Customer or any third party after delivery of such Product
                  ex-works, such dispute shall be referred for decision to an
                  independent expert (acting as an expert and not as an
                  arbitrator) to be appointed by agreement between Lonza and the
                  Customer or, in the absence of agreement by the President for
                  the time being of the Association of the British
                  Pharmaceutical Industry. The costs of such independent expert
                  shall be borne equally between Lonza and the Customer. The
                  decision of such independent expert shall be in writing and,
                  save for manifest error on the face of the decision, shall be
                  binding on both Lonza and the Customer.

         5.6      The provisions of Clauses 5.4 and 5.5 shall be the sole remedy
                  available to the Customer in respect of Product that fails to
                  meet Specification or that is adulterated.

6.       Price and Terms of Payment

         6.1      The Customer shall pay the Price in accordance with the Terms
                  of Payment.

         6.2      Unless otherwise indicated in writing by Lonza, all prices and
                  charges are exclusive of value added tax or of any other
                  applicable taxes, levies, imports, duties and fees of whatever
                  nature imposed by or under the authority of any government or
                  public authority, which shall be paid by the Customer. All
                  invoices are strictly net and payment must be made within
                  thirty (30) days of date of invoice. Payment shall be made
                  without deduction, deferment, set-off, lien or counterclaim of
                  any nature.

         6.3      Time for payment shall be of the essence. In default of
                  payment on due date:

                  6.3.1    interest shall accrue on any amount overdue at the
                           rate of 2% above the Base Rate from time to time of
                           Midland Bank plc, interest to accrue on a day to day
                           basis both before and after judgement; and

                  6.3.2    Lonza shall, at its sole discretion, and without
                           prejudice to any other of its accrued rights be
                           entitled to suspend the provision of the Services or
                           if the default of payment continues for One hundred
                           and fifty (150) days after the date of invoice to
                           treat the Agreement as


                                      34.
<PAGE>   35

                           repudiated by notice in writing to the Customer
                           exercised at any time thereafter provided that such
                           right to suspend Services or treat the Agreement as
                           repudiated shall not apply in circumstances where the
                           Customer has withheld payment for amounts disputed in
                           good faith (it being agreed that this proviso shall
                           apply to disputed amounts and not to any other
                           amounts due for payment forming part of the same or
                           another invoice).

7.       Warranty and Limitation of Liability

         7.1      Lonza warrants that:

                  7.1.1    the Services shall be performed in accordance with
                           Clause 4.1; and

                  7.1.2    the Product shall meet Specification, save with
                           respect to the first batch of Product delivered
                           pursuant to Schedule 5 Stage 5 where Lonza shall be
                           obliged only to use its reasonable endeavours to
                           produce Product that meets Specification.

         7.2      Clause 7.1 is in lieu of all conditions, warranties and
                  statements in respect of the Services and/or the Product
                  whether expressed or implied by statute, custom of the trade
                  or otherwise (including but without limitation any such
                  condition, warranty or statement relating to the description
                  or quality of the Product, its fitness for a particular
                  purpose or use under any conditions whether or not known to
                  Lonza) and any such condition, warranty or statement is hereby
                  excluded.

         7.3      Without prejudice to the terms of Clauses 3.4, 5.6, 7.1, 7.2
                  and 7.4 and, subject to Clause 7.6, the liability of Lonza for
                  any loss or damage suffered by the Customer as a direct result
                  of any breach of the Agreement or of any other liability of
                  Lonza (including misrepresentation and negligence) in respect
                  of the Services (including without limitation the production
                  and/or supply of the Product) shall be limited to the payment
                  by Lonza of damages which shall not exceed [*]. The 
                  limitation of liability set forth in the preceding sentence 
                  shall not apply to any breach by Lonza of Clauses 3.2, 8.1, 
                  8.2 and 8.3 of this Schedule 5.

         7.4      Subject to Clause 7.6, Lonza shall not be liable for the
                  following loss or damage howsoever caused (even if foreseeable
                  or in the contemplation of Lonza or the Customer):

                  7.4.1    loss of profits, business or revenue whether suffered
                           by the Customer or any other person; or

                  7.4.2    indirect or consequential lost whether suffered by
                           the Customer or any other person.

         7.5      The Customer shall indemnify and maintain Lonza promptly
                  indemnified against all claims, actions, costs, expenses
                  (including court costs and legal fees on a full indemnity
                  basis) or other liabilities whatsoever in respect of:

                  7.5.1    any liability under the Consumer Protection Act 1987,
                           unless, such liability is caused by the negligent act
                           or omission of Lonza in the production and/or supply
                           of the Product; and

                  7.5.2    any product liability (other than that referred to in
                           Clause 7.5.1) in respect of Product, unless such
                           liability is caused by the negligent act or omission
                           of Lonza in the production and/or supply of Product;
                           and

                  7.5.3    any negligent or wilful act or omission of the
                           Customer in relation to the use, processing, storage
                           or sale of the Product

         7.6      Nothing contained in these Standard Terms shall purport to
                  exclude or restrict any liability for death or personal injury
                  resulting directly from negligence by Lonza in carrying out
                  the Services or any liability for breach of the implied
                  undertakings of Lonza as to title.

         7.7      The obligations of the Customer and Lonza under this Clause 7
                  shall survive the termination for whatever reason of the
                  Agreement.

8.       Customer Information, Lonza Know-How and Patent Rights

         8.1      The Customer acknowledges that Lonza Know-How and Lonza
                  acknowledges that Customer Information with which it is
                  supplied by the other pursuant to the Agreement is supplied,
                  subject to Clause 8.4, in circumstances imparting an
                  obligation of confidence and each agrees to keep such Lonza

                  and to respect the other's proprietary rights therein and not
                  at any time for any reason whatsoever to disclose or permit
                  such Lonza Know-How or such Customer Information to be
                  disclosed to any third party.

         8.2      The Customer and Lonza shall each procure that all their
                  respective employees, consultants and contractors having
                  access to confidential Lonza Know-How or confidential Customer
                  Information shall be subject to the same obligations of
                  confidence as the principals pursuant to Clause 8.1 and shall
                  enter into secrecy agreements in support of such obligations.
                  Insofar as this is not reasonably practicable, the principals
                  shall take all reasonable

                  steps to ensure that any such employees, consultants and
                  contractors are made aware of such obligations.

         8.3      Lonza and the Customer each undertake not to disclose or
                  permit to be disclosed to any third party, or otherwise make
                  use of or permit to be made use of, any trade secrets or
                  confidential information relating to the technology, business
                  affairs or finances of the other, any subsidiary, holding
                  company or subsidiary or any such holding company of the
                  other, or of any suppliers, agents distributors, licensees or
                  other customers of the other which comes into its possession
                  under this Agreement.

         8.4      The obligations of confidence referred to in this Clause 8
                  shall not extend to any information which :

                  8.4.1    is or becomes generally available to the public
                           otherwise than by reason of a breach by the recipient
                           party of the provisions of this Clause 8;

                  8.4.2    is known to the recipient party and is at its free
                           disposal prior to its receipt from the other,

                  8.4.3    is subsequently disclosed to the recipient party, as
                           a matter of right without being made subject to an
                           obligation of confidence by a third party;

                  8.4.4    Lonza or the Customer may be required to disclose
                           under any statutory, regulatory, or similar
                           legislative requirement, subject to the imposition of
                           obligations of secrecy whether possible in that
                           relation provided that the party required to make the
                           disclosure shall first notify the other party who
                           shall be allowed to take what action he considers
                           necessary with respect to the proposed disclosure; or

                  8.4.5    is developed by an employee of the recipient party,
                           independently and without access to or use or
                           knowledge of the information supplied by the
                           disclosing party.

         8.5      The Customer acknowledges that:

                  8.5.1    Lonza Know-How and the Patent Rights are vested in
                           Lonza or Lonza is otherwise entitled thereto: and

                  8.5.2    the Customer shall not at any time have any right,
                           title, licence or interest in or to Lonza Know-How,
                           the Patent Rights or any other


                                      37.

                           intellectual property rights relating to the Process
                           which are vested in Lonza or to which Lonza is
                           otherwise entitled.

         8.6      Lonza acknowledges that, subject to Clause 4.5 above and save
                  as expressly stated herein. Lonza shall not by virtue of this
                  Agreement be granted any right, title or interest in the Cell
                  Line or the Product expressed by the Cell Line.

         8.7      The Customer shall not represent that it has any right, title,
                  or interest in or to Lonza Know-How, the Patent Rights or any
                  other intellectual property rights vested in Lonza or its
                  Affiliates and shall not seek or apply to register in its own
                  name any such rights. The Customer shall do all such acts and
                  things and sign all such deeds and documents as Lonza may in
                  its sole discretion reasonably require in respect of any
                  registration being made by Lonza or its Affiliates in
                  connection with such rights.

         8.8      The obligations of Lonza and the Customer under this Clause 8
                  shall survive the termination for whatever reason of the
                  Agreement.

9.       Termination

         9.1      If it becomes apparent to either Lonza or the Customer at any
                  stage in the provision of the Services that it will not be
                  possible to complete the Services for scientific or technical
                  reasons, a sixty (60) day period shall be allowed for
                  discussion to resolve such problems. If such problems are not
                  resolved within such period, Lonza and the Customer shall each
                  have the right to terminate the Agreement forthwith by notice
                  in writing.

         9.2      Lonza and the Customer may each terminate the Agreement
                  forthwith by notice in writing to the other upon the
                  occurrence of any of the following events:

                  9.2.1    if the other commits a material breach of the
                           Agreement which (in the case of a breach capable of
                           remedy) is not remedied within the time permitted
                           within Clause 6.3.2 for default of payment by the
                           Customer or otherwise within thirty (30) days of the
                           receipt by the other of notice identifying the breach
                           and requiring its remedy; or

                  9.2.2    if the other ceases for any reason to carry on
                           business or compounds with or convenes a meeting of
                           its creditors or has a receiver or manager appointed
                           in respect of all or any part of its assets or is the
                           subject of an application for an administration order

                           any analogous act or proceedings under foreign law.

         9.3      Notwithstanding the provisions of Clause 4.3 and Clause 10 of
                  this Schedule 5, if the Services listed in Stages 1-6 of
                  Schedule 2 as of the date of this Agreement have not been
                  completed by [*] the Customer may terminate the
                  Agreement at any time thereafter by written notice to Lonza.

         9.4      In the event of termination of the Agreement by either party
                  under Clause 9 or by the Customer under Clause 9.3 and
                  provided that Lonza is not also in material breach of the
                  Agreement at the same time whereby the Customer exercises his
                  right to termination the Agreement pursuant to Clause 9.2.1
                  then:

                  (a)      Customer shall pay to Lonza all amounts outstanding
                           and remaining to be paid for every stage of the
                           Services completed prior to termination and, for any
                           stage of the Services which remains incomplete upon
                           termination, a termination sum calculated by
                           reference to all costs incurred by Lonza (including
                           a reasonable profit) in carrying out activities for
                           any such stage of the Services and all expenses
                           reasonably incurred by Lonza in giving, effect to
                           such termination, including the costs of terminating
                           any commitments made pursuant to this Agreement (such
                           termination sum not to exceed the Price for each such
                           stage of the Services), and

                  (b)      Lonza shall deliver to the Customer any Product made
                           in accordance with the terms of this Agreement and a
                           report of all activities completed prior to
                           termination, and

                  (c)      Lonza shall be entitled to retain all amounts paid by
                           the Customer for every stage of the Services
                           completed prior to termination and any amount paid
                           for any stage of the Services which remains
                           incomplete upon termination.

         9.5      Upon the termination of the Agreement:

                  9.5.1    for whatever reason Lonza shall promptly return all
                           Customer Information to the Customer and shall
                           dispose of or return to the Customer the Cell Line
                           and any materials therefrom, as directed by the

                           promptly return to Lonza all Lonza Know-How it has
                           received from Lonza;

                  9.5.3    for whatever reason the Customer shall not thereafter
                           use or exploit the Patent Rights or the Lonza
                           Know-How in any way whatsoever other than for its own
                           internal purposes to meet regulatory requirements for
                           the Product (save in circumstances where Lonza
                           terminates the Agreement pursuant to Clause 9.2 when
                           no such use or exploitation is permitted);

                  9.5.4    for whatever reason Lonza may thereafter use or
                           exploit the Patent Rights or the Lonza Know-How in
                           any way whatsoever without restriction; and

                  9.5.5    for whatever reason Lonza and the Customer shall do
                           all such acts and things and shall sign and execute
                           all such deeds and documents as the other may
                           reasonably require to evidence compliance with this
                           Clause 9.5.

         9.6      Termination of the Agreement for whatever reason shall not
                  affect the accrued rights of either Lonza or the Customer
                  arising under or out of this Agreement and all provisions
                  which are expressed to survive the Agreement shall remain in
                  full force and effect.

10.      Force Majeure

         10.1     If Lonza is prevented or delayed in the performance of any of
                  its obligations under the Agreement by Force Majeure and shall
                  give written notice thereof to the Customer specifying the
                  matters constituting Force Majeure together with such evidence
                  as Lonza reasonably can give and specifying the period for
                  which it is estimated that such prevention or delay will
                  continue, Lonza shall be excused from the performance or the
                  punctual performance of such obligations as the case may be
                  from the date of such notice for so long as such cause of
                  prevention or delay shall continue and Lonza shall use its
                  reasonable efforts, so far as it is able, to stop the Force
                  Majeure. It is agreed that in the event of any delay in the
                  performance of Lonza's obligations for reasons of Force
                  Majeure under this clause, the dates applicable for the
                  payment of any additional sums for Lonza's Services under
                  Notes 3 and 4 to Clause 1 of Schedule 3 shall not change but
                  the dates applicable for the allowance of any credit against
                  the Price for Stages 3 and 5 of Schedule 2 as provided in
                  Notes 3 and 4, to Clause 1 of Schedule 3 shall be revised to


                                      40.

                  allow for each day's delay for reasons of Force Majeure under
                  this Clause 10.

         10.2     The expression "Force Majeure" shall be deemed to include any
                  cause affecting the performance by Lonza of the Agreement
                  arising from or attributable to acts, events, non-happenings,
                  omissions or accidents beyond the reasonable control of Lonza.

11.      Governing Law, Jurisdiction and Enforceability

         11.1     The construction, validity and performance of the Agreement
                  shall be governed by the laws of England, to the jurisdiction
                  of whose courts Lonza and the Customer submit.

         11.2     No failure or delay on the part of either Lonza or the
                  Customer to exercise or enforce any rights conferred on it by
                  the Agreement shall be construed or operate as a waiver
                  thereof nor shall any single or partial exercise of any
                  rights, power or privilege or further exercise thereof operate
                  so as to bar the exercise or enforcement thereof at any time
                  or times thereafter.

         11.3     The illegality or invalidity of any provision (or any part
                  thereof) of the Agreement or these Standard Terms shall not
                  affect the legality, validity or enforceability of the
                  remainder of its provisions or the other pans of such
                  provision as the case may be.

12.      Miscellaneous

         12.1     Neither party shall be entitled to assign, transfer, charge or
                  in any way make over the benefit and/or the burden of this
                  Agreement without the prior written consent of the other which
                  consent shall not be unreasonably withheld or delayed.

         12.2     The text of any press release or other communication to be
                  published by or in the media concerning the subject matter of
                  the Agreement shall require the written approval of Lonza and
                  the Customer.

         12.3     The Agreement embodies the entire understanding of Lonza and
