3.       Renovations to Hollister-Stier facilities are required to perform the
         Product Development Program(s). Such renovations will provide Client
         with CTM and early commercial scale-up capability for manufacturing
         Intermediates and Products. The renovations will create a manufacturing
         area dedicated to Client. Excess capacity of this dedicated area not
         utilized by Client may be used by Hollister-Stier upon written approval
         from Client. Such approval will not be unreasonably withheld. Client's
         equipment as defined herein may not be used by Hollister-Stier or
         Hollister-Stier clients.

         3.1      Hollister-Stier shall maintain at all times sufficient
                  staffing, supplies and equipment necessary for it to perform
                  Product Development Program(s) in accordance with the terms of

         3.2.1    During the term of this Agreement, Client shall, at its sole
                  expense and in a timely manner, deliver the equipment to
                  Hollister-Stier for installation and use solely in performing
                  the Product Development Program(s). The Parties shall
                  cooperate in the installation, calibration, confirmation,
                  qualification, validation, maintenance, cleaning and handling
                  of the equipment. As and to the extent reflected within the
                  applicable Product Development Program Documents annexed to
                  this Agreement, the calibration of the equipment will be at
                  Hollister-Stier's cost, but Client shall have the right to
                  review and approve all installation, calibration,
                  confirmation, qualification, validation, maintenance,
                  operation and cleaning procedures and data for the equipment
                  as stated within the applicable Product Development Program
                  Documents annexed to this Agreement. Cost for maintenance and
                  any requalification/revalidation of the equipment during the
                  term of this Agreement shall be borne by Hollister-Stier
                  except for such costs which are associated with the condition
                  of the equipment when it was delivered to Hollister-Stier,
                  which costs shall be borne by Client. During the term of this
                  Agreement, the equipment shall be exclusively dedicated to the
                  production of the Intermediate(s) and Product(s).

         3.2.2    At all times Client shall retain all legal and equitable title
                  to the equipment. While the equipment is located on
                  Hollister-Stier's premises, Hollister-Stier shall promptly
                  notify Client of any damages to the equipment. Any cost to
                  repair equipment that is damaged while in the custody of
                  Hollister-Stier, except to the extent caused by Client, will
                  be at Hollister-Stier's sole cost and expense. Hollister-Stier
                  must receive oral approval from Client, which will not be
                  unreasonably withheld, conditioned or delayed, before any
                  repairs to the equipment are performed. Hollister-Stier will
                  provide timely, written documentation to Client detailing the
                  repairs made to the equipment. Upon Client's written request,
                  or any termination or expiration of this Agreement, the
                  equipment and equipment related documentation (including all
                  calibration certificates and reports, use and cleaning logs,
                  confirmation, qualification, validation and maintenance
                  documents) shall be promptly returned to Client in good
                  condition, usual wear and tear excepted. Hollister-Stier shall
                  make its premises and personnel available during normal
                  business hours to assist with the removal and return of the
                  equipment, along with all equipment related documentation.
                  Client shall be responsible for all cost and expenses for the
                  removal of the equipment. The Parties shall reasonably
                  cooperate with regard to the restoration of the Product
                  Development Program facilities. While the equipment is located
                  on their premises, Hollister-Stier shall (1) at its sole
                  expense, safeguard and care for the equipment, subject to
                  normal wear and tear, (2) not grant any person a security
                  interest, lien or any other rights or interest in or to the
                  equipment; and (3) not remove, deface, alter, obscure or
                  obliterate any mark, tag or other information or
                  identification or statement of ownership placed on the
                  equipment by Client.

         authorized in writing in advance by Client, separately pay
         Hollister-Stier, on an as-costs-are-incurred basis in accordance with

                  Hollister-Stier regarding any contested amounts or questions
                  regarding an invoice or invoice item. Hollister-Stier agrees
                  to respond to requests by Client to clarify questions on any
                  invoice or invoice item, and Client agrees it will use its
                  commercially reasonable best efforts to resolve contested
                  invoice items in a timely fashion. Hollister-Stier
                  acknowledges and agrees that Client is not obligated to pay
                  such contested amounts otherwise due and payable within the
                  thirty (30) day period until such time as the contested issues
                  are resolved to the satisfaction of both Parties, and that
                  Client will not be subject to any penalty or finance charge
                  for such withheld payments. All payments due hereunder to

                  invoices as described herein, shall bear interest from the due
                  date at the rate of one and one-half percent (1.5%) per month
                  (or such other percentage, if lower, as shall not exceed the
                  maximum rate permitted by law).

                  The Costs shall not include sales, use, consumption, or excise
                  taxes of any taxing authority. Hollister-Stier shall notify

7.       Hollister-Stier and Client agree to the following Quality Control
         Procedures:

         7.1      Before authorizing shipment of any Batch or Lot of Product,
                  Hollister-Stier shall conduct and complete quality control
                  testing of the Intermediate and Batch or Lot of Product (as

                           upon in writing between the Parties, the Client shall
                           conduct and complete testing of the Intermediate and

                           according to Specifications. The extent and
                           responsibility of such testing will be mutually
                           agreed upon in writing by the Parties. For such
                           testing that may be performed by Hollister-Stier
                           under such a Product Development Program,
                           Hollister-Stier shall conduct such testing according
                           to the Specifications. Regardless of the
                           aforementioned, Hollister-Stier remains responsible
                           for confirming in writing that the Intermediate and
                           Product (1) were manufactured according to
                           Manufacturing Procedures and All Applicable Laws and
                           Regulations and (2) meet the applicable
                           Specifications.

         7.2      As per Section 7.1.1, each Intermediate and Batch or Lot of
                  Product shall be accompanied by a Certificate of Analysis
                  (COA).

         7.3      Each Batch or Lot shall be accompanied by a copy of the
                  Manufacturing Procedures for the delivered Batch or Lot of
                  Product and Batch or Lot of Intermediate used to manufacture
                  the delivered Batch or Lot of Product, including all test data
                  for the Batches and including all documents and test data
                  pertinent to Hollister-Stier's facilities, systems and
                  utilities involved in the manufacture of the Batches, all of
                  which are to be certified, stamped and signed by authorized
                  Hollister-Stier Quality Assurance personnel as being accurate
                  and complete and in accordance with this Agreement.

         7.4      Hollister-Stier may, at its sole discretion, transmit the
                  information specified in Sections 7.2 and 7.3 of this
                  Agreement separately from the applicable Batch or Lot of
                  Product, but Hollister-Stier acknowledges that such separate
                  transmission shall be made at or about the time of the
                  shipment of the Batch or Lot of Product.

         7.5      Hollister-Stier shall immediately notify Client and provide
                  complete documentation regarding any known deviations and or
                  errors by Hollister-Stier personnel from procedures set forth
                  in:

                  7.5.1    Manufacturing Procedures
                  7.5.2    Equipment procedures
                  7.5.3    Analytical test methods
                  7.5.4    Utilities, facility or other systems

         7.6      Hollister-Stier shall immediately notify Client and provide
                  complete documentation regarding of any out-of-specification
                  test data or results pertaining to any testing carried out in
                  relation to the manufacture of the Intermediate(s) and/or
                  Product(s) or operation of the facilities involved in the
                  manufacturing of the Intermediate(s) and/or Product(s).

         7.7      Hollister-Stier shall obtain Client's written approval prior
                  to implementing any further manufacturing, retesting or
                  resampling in connection with a deviation, error or out-of
                  specification test data or result for the Intermediate(s)
                  and/or Product(s), except for further manufacturing, retesting
                  or resampling procedures specifically authorized under Client
                  approved procedures in effect prior to the occurrence of the
                  deviation, error or the out-of-specification test data or
                  result.

         7.8      Except as provided in a procedure approved in writing by
                  Client, Hollister-Stier acknowledges and agrees that it shall
                  not rework or reprocess any non-conforming raw materials,
                  in-process materials, Intermediate(s) or Product(s).
                  Deviations undertaken by Hollister-Stier, unless expressly
                  approved in advance by Client, remain the responsibility of
                  Hollister-Stier.

         7.9      Any failure of any aseptic validation batch (media fill) or
                  Batches of Intermediate(s) or Product(s) resulting from such
                  deviations or errors by Hollister-Stier personnel shall be the
                  responsibility of Hollister-Stier. Hollister-Stier, at its
                  total expense, will be responsible for replacing a Batch of
                  Intermediate or Product that is rejected because of such
                  deviations or errors by Hollister-Stier personnel.

         7.10     Hollister-Stier is responsible for formally investigating and
                  documenting any failures to follow or deviations from
                  Manufacturing Procedures or analytical testing procedures, any
                  test or in-process test which fails to meet Specifications or
                  any failure of the equipment, utilities, facility or other
                  systems used to manufacture the Intermediate(s) and
                  Product(s), in accordance with Hollister-Stier's procedures
                  and cGMP Regulations. Such investigation shall be completed,
                  documented and provided to Client in a timely manner.

         7.11     Non-Conforming Intermediate or Product: Client from time to
                  time may conduct verification testing of Batches or Lots of
                  Intermediate(s) or Product(s) in accordance with the
                  Specifications ("Conformance Verification Testing"). Such
                  Conformance Verification Testing shall be initiated promptly
                  upon receipt of any Batches or Lots and shall be completed
                  within thirty (30) days. Client shall have the right to
                  reject, and to revoke any acceptances for, any Batches or Lots
                  of Intermediate(s) and all Batches or Lots of Product(s) made
                  from such Batches or Lots of Intermediate(s) that fail to meet
                  Specifications (including stability where a stability
                  specification is established and failure is due to a
                  manufacturing deficiency) and other material requirements
                  under this Agreement (including Intermediate or Product
                  determined not to have been manufactured in accordance with
                  this Agreement).

                  7.11.1   All claims of non-conformance arising from the
                           Conformance Verification Testing, except for good
                           cause, shall be deemed waived unless made by the
                           Client in writing and received by Hollister-Stier

                  7.11.2   If, after its own analysis of the Intermediate or
                           Product Batch(es) or Lot(s), or other information,
                           Hollister-Stier confirms the non-conformity,
                           Hollister-Stier shall manufacture and ship a
                           replacement Batch(es) or Lot(s) for the

                  7.11.3   If, after its own analysis of the Intermediate or
                           Product Batch(es) or Lot(s), Hollister-Stier does not
                           confirm the non-conformity, the Parties shall in good
                           faith agree to retest the Batch(es) or Lot(s) or
                           otherwise in good faith attempt to agree on a

                           Parties cannot resolve the issue, the Parties shall
                           submit the disputed Batch(es) or Lot(s) to a mutually

                           Hollister-Stier if so instructed by Hollister-Stier,
                           at Hollister-Stier's expense.

                           ultimately agreed or found to meet the Specifications
                           and other applicable requirements, Client shall
                           accept and pay for the Batch(es) or Lot(s).

                  unless prior written authorization has been obtained from the
                  disclosing Party. These obligations shall not apply to:

                  8.2.1    Information which, at the time of disclosure, is in

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

9.       Hollister-Stier represents, warrants and covenants to Client as
         follows:

         9.1      Commercially Reasonable Best Efforts: Hollister-Stier shall
                  use its commercially reasonable best efforts to perform the
                  services contemplated hereunder in accordance with the Product
                  Development Programs, it being recognized, however, that since
                  the services are of a development nature, there can be no
                  guarantee that the Product Development Programs will be
                  successfully completed, or successfully completed within the
                  contemplated time frame, despite Hollister-Stier's
                  commercially reasonable best efforts to do so. However,
                  following the successful completion of the required media fill
                  Batches, Hollister-Stier will be responsible for manufacturing
                  the Intermediate(s) and Product(s) to Specifications agreed
                  upon by the Parties in writing. If Hollister-Stier is, for any
                  reason, unable to meet any contemplated time frame in a
                  Product Development Program, it shall immediately notify
                  Client of same, as provided in Article

                  2. Hollister-Stier shall negotiate with Client a mutually
                  acceptable date of completion for the respective stage of the
                  Product Development Program, and Hollister-Stier shall use its
                  commercially reasonable best efforts to complete the Product
                  Development Program within such newly agreed upon time.


         9.2      Adherence to Specifications: Hollister-Stier shall, subject to
                  Section 9.1 hereof, produce the Intermediate(s) and Product(s)
                  in accordance with the Specifications for the Intermediates(s)
                  and Product(s).

         9.3      Qualified Personnel: Hollister-Stier shall engage and employ,
                  train and supervise professionally qualified personnel to
                  safely and lawfully perform the services contemplated
                  hereunder.

         9.4      Access: Client at its discretion may have its representatives
                  observe the performance of the Product Development Programs
                  under this Agreement, including any equipment, facility or
                  analytical qualification; manufacturing, inspection and bulk
                  packaging activities to provide appropriate technical support
                  and to ensure compliance with All Applicable Laws and
                  Regulations. Hollister-Stier, at its cost, will provide
                  Client's representatives carrying out such observations with
                  reasonable office space and telephone access. This access
                  shall not be used to conduct general GMP compliance audits

                  shall limit the number of auditors to a maximum of three (3)
                  individuals and the duration of the audit to three (3) days.

         9.6      General: Hollister-Stier shall exercise all due and reasonable
                  care with regard to all raw materials, components, equipment,
                  Intermediate(s) and Product(s) in its custody relating to the

                  skill, know-how, permits, approvals, and licenses to perform
                  the Product Development Program(s).

         9.7      Debarment: Hollister-Stier represents and warrants to Client
                  that it has neither been debarred nor subject to debarment and

                  connection with any Product Development Program any person who
                  has been debarred pursuant to Section 306 of the Act or who is
                  the subject of a conviction (or an investigation or
                  prosecution for an offense) described in this section.
                  Hollister-Stier agrees to inform Client immediately in writing
                  if it or any person who is performing a Product Development
                  Program hereunder on behalf of Hollister-Stier is debarred or
                  is the subject of a conviction described in Section 306 of the

                  is pending or, to the knowledge of Hollister-Stier, threatened
                  relating to debarment of Hollister-Stier or any person
                  performing the Product Development Program on behalf of

                  prescribed by a public authority or otherwise which could

                  manufacture or bulk packaging of the Intermediate(s) and
                  Product(s).




         11.3.    Indemnification Procedures:

                  11.3.1.  Any Party hereto seeking indemnification hereunder
                           (in this context the "Indemnified Party") shall
                           notify the other Party (in this context the
                           "Indemnifying Party") in writing reasonably promptly
                           after the assertion against the Indemnified Party any
                           Claim by a Third Party (a "Third Party Claim") in
                           respect of which the Indemnified Party intends to
                           base a Claim for indemnification hereunder.

                  11.3.2.  (1) The Indemnifying Party shall have the right, upon
                           written notice given to the Indemnified Party within
                           thirty (30) days after receipt of the notice from the
                           Indemnified Party of any Third Party Claim, to assume
                           the defense and handling of such Third Party Claim,
                           at the Indemnifying Party's sole expense, in which
                           case the provisions of Section 11.3.2 (2) below shall
                           govern. (2) The Indemnifying Party shall select
                           counsel reasonably acceptable to the Indemnified
                           Party in connection with conducting the defense and
                           handling of such Third Party Claim, and the
                           Indemnifying Party shall defend or handle the same in
                           consultation with the Indemnified Party, and shall
                           keep the Indemnified Party appraised of the status of
                           the Third Party Claim. The Indemnifying Party shall
                           not, without the prior written consent of the
                           Indemnified Party, which consent will not be
                           unreasonably withheld, agree to a settlement of any
                           Third Party Claim that could directly or indirectly
                           lead to liability or create any financial or other
                           obligation on the part of the Indemnified Party for
                           which the Indemnified Party is not entitled to
                           indemnification hereunder. The Indemnified Party
                           shall cooperate with the Indemnifying Party and shall
                           be entitled to participate in the defense or handling
                           of such Third Party Claim with its own counsel at its
                           own expense.

                  11.3.3.  (1) If the Indemnifying Party does not give written
                           notice to the Indemnified Party, within thirty (30)
                           days after receipt of the notice from the Indemnified
                           Party of any Third Party Claim, of the Indemnifying
                           Party's election to assume the defense or handling of
                           such Third Party Claim, the provisions of Section
                           11.3.3 (2) below shall govern. (2) The Indemnified
                           Party may, at the Indemnifying Party's expense,
                           select counsel in connection with conducting the
                           defense or handling of such Third Party Claim and
                           defend or handle such Third Party Claim in such
                           manner as it may deem appropriate, provided, however,
                           that the Indemnified Party shall keep the
                           Indemnifying Party timely appraised of the status of


                                       15

                           such Third Party Claim and shall not settle such
                           Third Party Claim without the prior written consent
                           of the Indemnifying Party, which consent shall not be
                           unreasonably withheld. If the Indemnified Party
                           defends or handles such Third Party Claim, the
                           Indemnifying Party shall cooperate with the
                           Indemnified Party and shall be entitled to
                           participate in the defense or handling of such Third
                           Party Claim with its own counsel and at its own
                           expense.

                  11.3.4.  If the Indemnified Party intends to seek
                           indemnification hereunder, other than for a Third
                           Party Claim, then it shall notify the Indemnifying
                           Party in writing within three months after its
                           discovery of facts upon which it intends to base its
                           Claim for indemnification hereunder; provided,
                           however, the failure to timely give such notice shall
                           limit the Indemnifying Party's liability for
                           indemnification only to the extent the Indemnifying
                           Party's defense of such matter has been prejudiced.

                  11.3.5.  Except with regard to fraud, the indemnification
                           remedies in this Article 11, enforced in accordance
                           with Section 13.3, shall constitute the sole and
                           exclusive remedies of the Parties with respect to any
                           matters arising under or relating to this Agreement.

         11.4.    Survival of Indemnification Obligations: The provisions of
                  this Article 11 shall survive the expiration or termination of
                  this Agreement for a period of five (5) years.

         11.5.    Limitation of Liability and Claims: Hollister-Stier shall not
                  be liable to Client for indirect, special, punitive, or
                  consequential damages of any kind, including without
                  limitation lost profits or loss of good will or otherwise.
                  Neither Party's liability to the other under this Agreement
                  shall exceed five million dollars ($5,000,000.00).

         11.6.    Insurance: Both Client and Hollister-Stier shall obtain and
                  maintain, either itself or through one or more of its
                  affiliates, with reputable carriers, product liability
                  insurance with limits of not less than $10,000,000 per
                  claim/annual aggregate by no later than the scheduled
                  manufacturing date for the first CTM Batch of Product(s)
                  delivered as part of the first Product Development Program(s)
                  conducted under this Agreement. Each Party hereto shall have
                  its insurance carrier(s) furnish the other Party hereto with a
                  certificate that such insurance is in force. In the event of
                  any proposed cancellation, non-renewal, or material adverse
                  change in such coverage, the other Party hereto shall be given
                  at least thirty (30) days advance written notice thereof.

                  either Party in the event of material breach or default by the
                  other Party of the terms and conditions hereof; provided,
                  however, the other Party shall first give to the defaulting
                  Party written notice of the proposed termination or

                                   ARTICLE 13

                        FORCE MAJEURE/DISPUTE RESOLUTION

13.      The Parties agree to the following Force Majeure/Dispute resolution
         clauses:

         13.1.    Effect of Force Majeure: Neither Party shall be held liable or
                  responsible for any loss or damages resulting from any failure
                  or delay in its performance due hereunder (other than payment
                  of money) caused by force majeure. As used herein, force
                  majeure shall be deemed to include any condition beyond the
                  reasonable control of the affected Party including, without
                  limitation, Acts of God, strikes or other labor disputes, war,
                  riot, earthquake, tornado, hurricane, fire, civil disorder,
                  explosion, accident, flood, sabotage, lack of or inability to
                  obtain adequate fuel, power, materials, labor, containers,
                  transportation, supplies or equipment, compliance with
                  governmental requests, laws, rules, regulations, orders or
                  actions; inability despite good faith efforts to renew
                  operating permits or licenses from local, state or federal
                  governmental authorities; breakage or failure of machinery or
                  apparatus; national defense requirements; or supplier strike,
                  lockout or injunction. Hollister-Stier shall notify Client of
                  any foreseeable force majeure events, including, but not
                  limited to foreseeable strikes and other labor disputes,
                  shipping interruptions or problems, and inability to procure
                  supplies necessary for Hollister-Stier to perform any of its
                  obligations under this Agreement.

         13.2.    Notice of Force Majeure: In the event either Party is delayed
                  or rendered unable to perform due to force majeure, the
                  affected Party shall give notice of the same and its expected
                  duration to the other Party promptly after the occurrence of
                  the cause relied upon, and upon the giving of such notice the
                  obligations of the Party giving the notice will be suspended
                  during the continuance of the force majeure; provided,
                  however, such Party shall take commercially reasonable steps
                  to remedy or mitigate the force majeure with all reasonable
                  dispatch. The requirement that force majeure be remedied with
                  all reasonable dispatch shall not require the settlement of
                  strikes or labor controversies by acceding to the demands of
                  the opposing party.

         13.3.    Dispute Resolution: The Parties hereto agree to perform the
                  terms of this Agreement in good faith, and to attempt to
                  resolve any controversy, dispute or claim arising hereunder in
                  good faith. Any dispute regarding the validity, construction,
                  interpretation, or performance of this Agreement (other than
                  provisions, hereof relating to any intellectual property,
                  rights, or the confidentiality obligations contained in
                  Article 8 hereof) shall be (1) first attempted to be resolved
                  between the CEO/President of each Party and failing that (2)

                  Arbitration Association ("AAA"); provided, however, that
                  nothing in this Section 13.3 shall be construed to preclude
                  either Party from seeking provisional remedies, including, but
                  not limited to, temporary restraining orders and preliminary
                  injunctions, from any court of competent jurisdiction, in
                  order to protect its rights pending arbitration, but such
                  preliminary relief shall not be sought as a means of avoiding
                  arbitration. Any arbitration hereunder shall be submitted to
                  an arbitration tribunal made up of three (3) members, one of
                  whom shall be selected by Client, one of whom shall be
                  selected by Hollister-Stier, and one of whom shall be selected
                  by the other two arbitrators. All arbitration proceedings
                  shall be conducted in English. The order or award of the
                  arbitrators shall be final and may be enforced in any court of
                  competent jurisdiction. The prevailing Party in any legal or
                  arbitration action brought by one Party against the other
                  shall be entitled, in addition to any other rights and
                  remedies it may have, to reimbursement for its expenses
                  incurred thereby, including court cost and reasonable
                  attorney's fees. The Parties shall have the right of limited
                  prehearing discovery, including:

                  13.3.1.  exchange of witness lists,
                  13.3.2.  exchange of documentary evidence and reasonably
                           related documents,
                  13.3.3.  written interrogations, and
                  13.3.4.  subject to reasonable discretion of the arbitrators
                           and upon good cause shown depositions under oath of
                           any witnesses who are to be called to testify at the
                           arbitration hearing.

         13.4.    As soon as the discovery is concluded, the arbitrators shall
                  hold a hearing in accordance with the aforesaid AAA rules.

                  and private placement memoranda and documentation, using
                  reasonable commercial efforts to protect the confidentiality
                  of the terms of this Agreement.

         15.5.    Severability: Each Party hereby expressly agrees that it has
                  no intention to violate any public policy, statutory or common
                  laws, rules, regulations, treaty or decision of any government
                  agency or executive body of any country or community or
                  association of countries; that if any word, sentence,
                  paragraph, clause or combination thereof in this Agreement is
                  found by a court or executive body with judicial powers having
                  jurisdiction other this Agreement or either Party hereto, in a
                  final unappealed order, to be in violation of any such
                  provisions in any country or community or association of
                  countries, such words, sentences, paragraphs, clauses or
                  combination shall be inoperative in such country or community
                  or association of countries and the remainder of this
                  Agreement shall remain binding upon the Parties, so long as
                  enforcement of the remainder does not violate the Parties'
                  overall intentions in this transaction.

         15.6.    Assignment; Subcontractors: This Agreement may not be assigned
                  or otherwise transferred by either Party without the prior
                  written consent of the other Party; provided, however, either
                  Party may, without such consent, assign this Agreement

                  15.6.1.  in connection with the transfer or sale of all or
                           substantially all of the assets of such Party or the
                           line of business of which this Agreement forms a
                           part,

                  15.6.2.  in the event of a merger or consolidation of a Party

                           hereunder.

                  Any purported assignment in violation of the preceding shall
                  be void. Any permitted assignee shall assume all obligations
                  of its assignor under this Agreement. No assignment shall
                  relieve either Party of responsibility for the performance of
                  any obligation which accrued prior to the effective date of
                  such assignment.

         15.7.    Governing Law: This Agreement shall be governed by and
                  construed in accordance with the laws of the state of
                  Washington, irrespective of any conflicts of law rule which
                  may direct or refer such determination of applicable law to
                  any other state; and if this Agreement were performed wholly
                  within the state of Washington.

         15.9.    Continuing Obligations: Termination, assignment or expiration
                  of this Agreement shall not relieve either Party from full
                  performance of any obligations incurred prior thereto.

         15.10.   Waiver: Neither Party's waiver of any breach or failure to
                  enforce any of the terms and conditions of this Agreement, at
                  any time, shall in any way affect, limit or wave such Party's
                  right thereafter to enforce and compel strict compliance with
                  every term and condition of this Agreement.

         15.11.   Construction: This Agreement has been jointly prepared on the
                  basis of the mutual understanding of the Parties and shall not
                  be construed against either Party by reason of such Party's
                  being the drafter hereof or thereof.

         15.12.   Exhibits, Schedules and Attachments: Any and all exhibits,
                  schedules and attachments referred to herein form an integral
                  part of this Agreement and are incorporated into this
