HALOZYME should decide to change the Specifications with regard to the Bulk Drug
Substance, HALOZYME shall be liable for any and all additional costs for
materials, including but not limited to, raw materials, shipping materials or
other items previously purchased by AVID in reasonable anticipation of use under
this Agreement which have become unnecessary as a result of such change and
cannot be used by AVID with its manufacturing efforts for its other customers
(collectively, the "Incurred Material Costs"); provided, however, that AVID has
notified HALOZYME in writing of such Incurred Material Costs prior to the date
of any amendment to the Specifications and HALOZYME has agreed in writing to pay
to AVID such Incurred Material Costs.

                  2.2.4 In the event that any change contemplated under this
Section 2.2 that is requested by HALOZYME has the effect of delaying a scheduled
manufacturing run, AVID shall use its reasonable best efforts to accommodate
such run as soon as reasonably practicable. The parties agree that AVID shall
not be liable to HALOZYME for any loss, damages incurred by HALOZYME to the
extent resulting from such delay.

                  2.2.5 In the event that HALOZYME requests a change, whether
planned or unplanned that causes a delay to a manufacturing run under the
Manufacturing Schedule, HALOZYME shall be liable for any and all Incurred
Material Costs; provided, however, that AVID has notified HALOZYME in writing of
such Incurred Material Costs prior to the date of any amendment to the
Manufacturing Schedule and HALOZYME has agreed in writing to pay to AVID such
Incurred Material Costs. An alteration to the agreed upon Manufacturing Schedule
that is requested by HALOZYME and results in HALOZYME losing a manufacturing
time slot will result in forfeiture of the deposit for that manufacturing time
slot as identified and set forth in the Purchase Price unless AVID, using its
reasonable best efforts, is able to fill such manufacturing time slot with a
manufacturing project for one of its other customers.

                  2.2.6 In the event that AVID requests a change, whether
planned or unplanned, that causes a delay to a manufacturing run under the
Manufacturing Schedule, HALOZYME shall not be liable for any and all Incurred
Material Costs and shall not lose its deposit for any manufacturing slots
identified and set forth in the Purchase Price. AVID shall, in good faith and
using commercially reasonable efforts, limit any delay resulting from such
change to less than thirty (30) days; provided, however, that if the change
requested by AVID results in a delay to the manufacturing run under the
Manufacturing Schedule longer than sixty (60) days

*** Confidential material redacted and submitted separately to the Commission



                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

in the aggregate, the parties shall mutually agree upon a fair and equitable
reduction in the Purchase Price for the applicable Bulk Drug Substance to
compensate HALOZYME for such delay, provided that such delay was not caused by
HALOZYME.

            2.3   Quality Agreement. At the reasonable request of either party,
the parties shall negotiate in good faith amendment(s) to the Quality Agreement
(Exhibit C) (a) to address matters specific to the Production of Bulk Drug
Substance for sale and use outside the United States, and (b) to address
regulatory concerns raised by a Regulatory Authority or concerns relating to
regulatory compliance or quality raised by a party.

            2.4   Order of Precedence. In the event that the terms of the Bulk
Drug Substance Master Plan or Quality Agreement are inconsistent with the terms
of this Agreement, this Agreement shall control, unless otherwise explicitly
agreed to in writing by the parties. The Bulk Drug Substance Master Plan and
Quality Agreement shall be deemed to be incorporated herein and by reference and
made a part of this Agreement.

            2.5   Raw Materials and Testing. HALOZYME authorizes AVID to procure
from qualified vendors in accordance with the Bulk Drug Substance Master Plan
all necessary raw materials and supplies required to meet the manufacturing
timeline per the Manufacturing Schedule. HALOZYME shall provide AVID with at
least four (4) months advance written notice if HALOZYME would like to delay the
purchase of the raw materials and supplies. In addition, HALOZYME authorizes
AVID to ship out all necessary samples for outside testing as soon as reasonable
practical in accordance with the Bulk Drug Substance Requirements. In accordance
with the Bulk Drug Substance Master Plan, HALOZYME shall pay AVID for all raw
materials, supplies, and outside testing charges procured on behalf of HALOZYME
to manufacture the BDS. In the event the raw materials and supplies are utilized
for other customers of AVID, HALOZYME shall receive credit from AVID for the raw
materials and supplies utilized by other customers of AVID.

                  In the event that a raw material is either not available
despite being ordered in advance adhering to supplier's stated lead-time, or on
back order from a vendor, or received raw materials do not meet Specifications,
and in each case such delay is out of the reasonable control or foresight of the
parties, the Manufacturing Schedule shall be delayed at no cost or liability to
either party; provided, however, that if such delay is caused solely by AVID and
is longer than thirty (30) days in the aggregate, the parties shall mutually
agree upon a fair and equitable reduction in the Purchase Price for the
applicable Bulk Drug Substance to compensate HALOZYME for such delay, provided
that such delay was not caused by HALOZYME. HALOZYME and AVID will use their
reasonable best efforts to locate alternative sources of the back ordered raw
material. If a vendor is located, said vendor must be qualified prior to any
material being used in the manufacture of the Bulk Drug Substance. AVID will
qualify vendor under the terms of this Agreement. AVID shall provide HALOZYME
with the right to secure the next available manufacturing time slot once the raw
material has been received and tested to meet Specifications.

            3.2   Documentation. A master batch record and associated SOP's
detailing the processes and procedures for manufacturing the Bulk Drug Substance
in conformance with the Specifications shall be generated by AVID; provided,
however that they must be reviewed and approved in writing by AVID and by
HALOZYME prior to Production (the "Master Batch Record"). Any substantive change
(e.g., one that would require a change in revision level per AVID Document
Control SOP) to the approved Master Batch Record must be reviewed and approved
in writing by AVID and HALOZYME prior to any change being implemented. It is the
responsibility of HALOZYME to ensure that proper Regulatory Authorities approve
the suggested changes, if necessary. Each Batch of Bulk Drug Substance shall be
Produced according to, and shall be documented in, a production copy of the
Master Batch Record, known as an Executed Batch Record. Each copy of the
Executed Batch Record for such Batch of Bulk Drug Substance shall be assigned a
unique batch number by AVID. Any deviation from the manufacturing process
specified in the Master Batch Record must be documented in the copy of the
Master Batch Record for that Batch using a deviation form. AVID shall provide

      Notwithstanding the foregoing, if HALOZYME cancels a manufacturing run
less than *** prior to the scheduled start of the manufacturing run per the
Manufacturing Schedule, HALOZYME shall not owe a cancellation fee if AVID is
able to fill such slot with another of its customers. AVID shall use its best
efforts to attempt to fill a slot created by any such cancellation. HALOZYME
shall notify AVID as soon as practical of any planned or anticipated
manufacturing delays.

                  3.4.3 Monetary Default. If HALOZYME defaults on any payments
due, interest shall accrue on any amount overdue at the rate of one percent (1%)
per month or the maximum rate allowed by law, whichever is lower, and for so
long as such overdue amount is unpaid, AVID shall be entitled to suspend any
additional services under this Agreement by providing written notice to
HALOZYME. The parties agree that AVID shall not be liable to HALOZYME for any
loss, damages incurred by HALOZYME to the extent resulting from such delay.

            3.5   Equipment. During the term of this Agreement, upon the prior
written approval of HALOZYME in each case, HALOZYME shall fund the purchase of

as applicable, shall not occur more than one (1) time per calendar year or
exceed 3 days in length, after successful completion of a pre-approval
inspection audit, unless required by AVID's compliance status or HALOZYME's
needs or obligations as a license holder. In connection with performing such
audits, HALOZYME shall comply with all reasonable rules and regulations
promulgated by AVID relating to confidentiality, safety and security.

            4.3   Testing. In accordance with the Quality Agreement, AVID shall
test, or cause to be tested by third party testing facilities audited by AVID,
and approved by HALOZYME, in accordance with the Bulk Drug Substance
Requirements, each Batch of Bulk Drug Substance produced pursuant to this
Agreement before delivery to HALOZYME. Any third party testing facilities chosen
by HALOZYME and not previously audited by AVID will be audited by AVID, at
HALOZYME expense. A Certificate of Analysis and a Certificate of Compliance for
each Batch of Bulk Drug Substance delivered to HALOZYME shall set forth the
items tested, specifications, and test results in accordance with the Quality
Agreement. AVID shall send, or cause to be sent, to HALOZYME such certificates
along with one (1) copy of the Released Executed Master Batch Record two (2)
weeks after final QA review (in accordance with the Quality Agreement) and
approval of the executed Master Batch Record. As the drug license holder,
HALOZYME shall assume full responsibility for final disposition of each lot of
Bulk Drug Substance. Prior to use of any raw material or component in the
manufacture of Bulk Drug Substance, HALOZYME shall review the information AVID
has on file regarding the vendor, part number and any relevant testing data used
to qualify that raw material or component. HALOZYME shall approve the use of any
such vendor in writing prior to the initiation of any commercial manufacturing.
In the event a raw material or component is determined at a later stage to
contain an adventitious agent or contaminant liability will be determined
subsequent to an investigation to be conducted by the parties.

            4.4   Permits and Licenses. HALOZYME shall have sole responsibility,
at its expense, for obtaining all permits and licenses, including any licenses
specific (i.e., including, but not limited to licenses for specific cell lines,
expression systems, purification and specific media components, etc.) for
manufacture of the Bulk Drug Substance, necessary or required for the sale,
marketing and commercialization of each Bulk Drug Substance manufactured by AVID
hereunder. AVID shall be responsible, at its expense, to obtain and maintain all
permits and licenses required for it to carry out its regulatory and Production
obligations hereunder. AVID, at HALOZYME's request and expense, shall cooperate
with HALOZYME by assisting in

                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

preparing and filing any necessary documents to support HALOZYME's applications
for permits and licenses.

            4.5   Regulatory Requirements. Each party shall use its reasonable
best efforts to promptly notify the other of new regulatory requirements of
which it becomes aware which are relevant to the Production of a Bulk Drug
Substance under this Agreement and which are required by the Regulatory
Authorities or other applicable laws or governmental regulations, and shall
confer with each other with respect to the best means to comply with such
requirements.

            4.6   AVID's Facility. AVID is responsible for cGMP compliance with
all Federal, State and local Regulatory Authorities, laws and regulations
("Regulations") as they apply to AVID's facility. AVID shall have no
responsibility for compliance with Regulations as they relate specifically to
final filling, labeling development or marketing. HALOZYME assumes
responsibility for all contact with the FDA and other Regulatory Authorities
pertaining specifically to the Bulk Drug Substance; provided, however, AVID
shall provide to HALOZYME all such information as HALOZYME requires in
connection with such contacts with the FDA and other regulatory bodies and AVID
agrees to otherwise fully cooperate with HALOZYME in connection with such
matters.

            4.7   Regulatory Approvals. AVID shall provide product specific
information at HALOZYME's expense, including documents and assistance for
HALOZYME in preparation of submissions to Regulatory Authorities designated by
HALOZYME in support of HALOZYME's 510(k)s, INDs, New Drug Applications (NDAs),
or similar applications required of US or foreign governments and licenses.

            4.8   Regulatory Authority Inspections.

                  4.8.1 Interaction with Regulatory Authorities. All interaction
with Regulatory Authorities (both written and oral) that directly affects Bulk
Drug Substance or the Production of Bulk Drug Substance shall be conducted in
accordance with the provisions of this Section 4. At HALOZYME's request, AVID
will authorize Regulatory Authorities to review on HALOZYME's behalf
applications related to the Production of the Bulk Drug Substance.

                  4.8.2 Bulk Drug Substance Pre-Approval Inspection. In the case
of the Bulk Drug Substance Pre-Approval Inspection by the FDA or other
Regulatory Authorities related to HALOZYME's Bulk Drug Substances, the following
shall apply: (a) AVID immediately shall inform HALOZYME of the notice of such
inspection; (b) AVID shall permit a representative of HALOZYME to be present at
such inspection providing the HALOZYME representative is a non-participant in
any such meeting, provided that information of other clients of AVID is not
discussed; (c) AVID shall permit such representative of HALOZYME to be present
as a non-participant in, each daily wrap up session for such inspection and the
post-inspection wrap up session for such inspection, provided that information
of other clients of AVID is not discussed; (d) AVID promptly shall provide
HALOZYME with copies of all written materials, including, without limitation,
copies of any Notice of Inspection (FDA Form 482 or equivalent), other notice of

*** Confidential material redacted and submitted separately to the Commission



                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

Establishment Inspection Report (EIR) relating to such inspection (provided that
AVID shall have the right to redact such documents to the extent necessary to
maintain other clients confidentiality, if applicable), and (e) AVID shall
provide HALOZYME with advance copies of all proposed responses to any such
inspections, notices or actions, shall permit HALOZYME reasonable opportunity
(provided that such does not prejudice AVID's ability to respond within 15
working days of its receipt of the Form 483 or equivalent) to review and comment
on each such response, shall consider HALOZYME's comments thereon, and shall
provide HALOZYME with copies of each such response as submitted. Notwithstanding
the foregoing, (i) nothing contained in this Section 4.8.2 shall be deemed to
give HALOZYME the authority to deal directly with the FDA in resolving any
matter arising out of the Pre-Approval Inspection without the prior written
consent of AVID, and (ii) AVID shall use its best efforts to promptly and
diligently correct the deviations and observations identified in the Form 483 or
other regulatory inspection summary. AVID shall implement such corrections at
AVID's expense. If AVID's failure to resolve any deviations and observations
results in delays of HALOZYME's ability to obtain product approval or bring
products to market, the parties shall mutually agree upon a fair and equitable
reduction in the Purchase Price to compensate HALOZYME for such failure. In no
event shall AVID be liable for any lost profits to the extent due to a delay
caused by Regulatory Authorities.

                  4.8.3 Other Bulk Drug Substance Specific Inspections. In the
case of an inspection (other than the Bulk Drug Substance Pre-Approval
Inspection) by a Regulatory Authority the following shall apply: (a) AVID shall,
as soon as reasonably practicable, inform HALOZYME by phone or e-mail to their
head of regulatory and quality of the notice of such inspection; (b) AVID shall,
to the extent the inspection relates to the Production of Bulk Drug Substance
provide HALOZYME with copies of all written materials, including without
limitation copies of any Notice of Inspection (FDA Form 482 or equivalent),
other notice of inspection, notice of violation, other similar notice, or
Inspectional Observations (FDA Form 483 or equivalent) received by AVID relating
to such inspection, and Establishment Inspection Report (EIR) relating to such
inspection (provided that AVID shall have the right to redact such documents to
the extent necessary to maintain other clients confidentiality);and (e)AVID
shall provide HALOZYME with appropriately redacted copies of all responses to
any such inspections, notices or actions as finally submitted. Notwithstanding
the foregoing, AVID shall use its best efforts to promptly and diligently
correct the deviations and observations identified in the Form 483 or other
regulatory inspection summary. AVID shall implement the corrections at AVID's
expense. If AVID's failure to resolve any deviations and observations results in
delays of HALOZYME's ability to obtain product approval or bring products to
market, the parties shall mutually agree upon a fair and equitable reduction in
the Purchase Price to compensate HALOZYME for such failure

                  4.8.4 Other Inspections. In the case of an inspection by a
Regulatory Authority of an AVID facility that does not directly affect the
Production of Bulk Drug Substances, the following shall apply: (a) AVID promptly
shall provide HALOZYME with copies of all written materials (with confidential
information that does not directly affect the Production of Bulk Drug Substances
redacted therefrom), including without limitation copies of any Notice of
Inspection (FDA Form 482 or equivalent), other notice of inspection, notice of

with copies of all responses to any such inspections, notices or actions (with
confidential information that does not directly affect the Production of Bulk
Drug Substances redacted therefrom).

            4.9   Accelerated Delivery. In the event of any adverse regulatory
action, including without limitation receipt by AVID from the FDA or other
Regulatory Authorities of a warning letter, injunction, restraining order,
notice of intent to do any of the foregoing, or notice of intent to revoke or
suspend any of AVID's licenses that directly affect Bulk Drug Substance or the
Production of Bulk Drug Substance made from AVID's produced Bulk Drug Substance,
AVID shall deliver to HALOZYME or its affiliates, within forty eight (48) hours
of a written request from HALOZYME and after tender by HALOZYME of the
applicable Purchase Price, all Bulk Drug Substance requested by HALOZYME in
AVID's possession; provided that AVID is not prohibited from doing so per any
applicable law, regulation, court or agency order, notice, or ruling.

      5.    ACCEPTANCE OF BULK DRUG SUBSTANCE.

            5.1   Bulk Drug Substance Conformity. With respect to each Batch, no
later than thirty (30) calendar days from AVID'S delivery of the COA and
Released Executed Batch Record (provided by HALOZYME) for such Batch, HALOZYME
shall either (a) accept the Batch and title shall transfer to HALOZYME, or (b)
notify AVID in writing of the failure of the Batch to meet the Bulk Drug
Substance Requirements. All risk of loss for the Bulk Drug Substance shall pass
to HALOZYME at the close of business on the 30th calendar day following the
later of delivery of the COA and Released Executed Batch Record for such Batch
unless HALOZYME has notified AVID of the failure of the Batch to meet the Bulk
Drug Substance Requirements. It shall be the responsibility of HALOZYME to
provide AVID the Shipping Instructions for the Bulk Drug Substance and any
labeling requirements for the Bulk Drug Substance. All reasonable costs and
expenses associated with HALOZYME's packaging and shipping requests shall be
paid by HALOZYME. Notwithstanding the foregoing, if HALOZYME accepts a Batch but
wishes to have AVID store the Bulk Drug Substance under a bill and hold
arrangement beyond the thirty (30) day period, HALOZYME shall provide AVID with
written notice to store the BDS and shall pay AVID *** a month per Batch (not to
exceed six (6) months) and AVID shall store such Batch in accordance with cGMP
at its facilities ("Bill and Hold Arrangement"). Promptly following the end of
such six (6) month period, AVID shall, at HALOZYME's expense, ship the remaining
BDS (if any) to such as address as HALOZYME shall provide. Under the bill and
hold arrangement, HALOZYME shall provide to AVID, prior to the close of the
thirtieth (30th) calendar day following the later of delivery of the COA and
Released Executed Batch Record, a written fixed schedule covering a period not
to exceed such six (6) month period for delivery of the BDS. Other than AVID's
obligations relating to the storage and delivery of the BDS, AVID shall not be
responsible for any additional performance obligations with respect to the BDS
after the thirty (30) day period. HALOZYME agrees that all


*** Confidential material redacted and submitted separately to the Commission


                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

risk of loss of the BDS shall transfer to HALOZYME at the close of the thirtieth
(30th) calendar day following AVID'S delivery of the COA and Released Executed
Batch Record for such Batch under any Bill and Hold Arrangement. HALOZYME shall
pay all amounts required to be paid to AVID pursuant to this Agreement no later
than thirty (30) days from the date of invoice in accordance with the Purchase
Price.

                  5.1.1 If HALOZYME fails to notify AVID within the time period
specified in Section 5.1 that any Bulk Drug Substance does not conform to the
Bulk Drug Substance Requirements, then HALOZYME shall be deemed to have accepted
such Bulk Drug Substance and waived its right to revoke acceptance.

                  5.1.2 If HALOZYME believes any Bulk Drug Substance does not
conform to the Bulk Drug Substance Requirements, it shall give written notice to
AVID specifying the manner in which such Bulk Drug Substance fails to meet the
Bulk Drug Substance Requirements. Guidelines for resolving any disputed claims
regarding conformity of Bulk Drug Substance are set forth in Section 5.1.3.

                  5.1.3 If there is any dispute concerning whether the Bulk Drug
Substance complies with the Bulk Drug Substance Requirements or whether any such
failure is due (in whole or in part) to acts or omissions of HALOZYME after
delivery of the Bulk Drug Substance, the parties first shall refer such matter
to the head of Quality Department of each company for amicable settlement. In
the event that the head of each Quality Department does not settle such dispute
within ten (10) business days (or such later time as the parties may agree in
writing) after one party referred the matter to the other company's Quality
Department, a sample of the Bulk Drug Substance retained by AVID and a sample of
the Bulk Drug Substance delivered to HALOZYME shall be exchanged between the
parties for a counter-check. If such counter-check does not resolve the dispute,
a sample of the Bulk Drug Substance retained by AVID and a sample of the Bulk
Drug Substance delivered to HALOZYME shall be submitted to an independent,
qualified third party laboratory that is mutually acceptable and selected by the
parties promptly in good faith. Such laboratory shall determine whether the Bulk
Drug Substance delivered to HALOZYME met the Bulk Drug Substance Requirements at
the time of delivery by AVID, and such laboratory's determinations shall be
final. In the event the Bulk Drug Substance provided by AVID to the independent,
qualified third party laboratory meets the Bulk Drug Substance Requirements,
HALOZYME shall immediately and without delay pay AVID the Purchase Price. The
non-prevailing party shall bear the costs of such laboratory or consultant,
except as set forth in Section 5.2.2.

         5.2 Remedies for Non Conforming Bulk Drug Substance.

                  5.2.1 In the event AVID agrees that any Bulk Drug Substance is
non-conforming or the independent laboratory determines that the shipment of
Bulk Drug Substance is non-conforming, AVID shall use its best efforts to
replace such non-conforming Bulk Drug Substance as soon as practical in the next
available manufacturing time slot from the date of determination by the third
party of non-conformity or agreement by AVID of such non-conformity.


*** Confidential material redacted and submitted separately to the Commission



                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

                  5.2.2 In the event AVID agrees, or the independent laboratory
or consultant determines, that Bulk Drug Substance is non-conforming due in
whole or in part to the negligence or willful misconduct of AVID, then to the
extent such nonconformity results from the negligence or willful misconduct of
AVID, AVID shall be responsible for the cost of Production and delivery of the
replacement Bulk Drug Substance, subject to, and except as otherwise set forth
in, the provisions of Section 11.

      6. BULK DRUG SUBSTANCE RECALLS. Each party promptly shall notify the other
if any Batch of Bulk Drug Substance is alleged or proven to be the subject of a
recall, market withdrawal or correction. HALOZYME shall be responsible for
coordinating any recall, market withdrawal or field correction of Bulk Drug
Substance, and recall, market withdrawal or correction shall be conducted in
accordance with the provisions of the Quality Agreement. HALOZYME shall provide
AVID with a copy of all documents relating to such recall, market withdrawal or
field correction. AVID shall cooperate with HALOZYME (including providing
HALOZYME with all data, information and documents requested by HALOZYME) in
connection with such recall, market withdrawal or field correction, at
HALOZYME's expense. Unless such recall is caused solely by the negligence,
omission or willful misconduct of AVID or solely by AVID's breach of its
warranties or obligations under this Agreement, HALOZYME shall be responsible
for all of the costs and expenses of such recall, market withdrawal or field
correction. In the event a recall, market withdrawal or field correction is
necessary because of AVID's breach of this Agreement or its negligence, omission
or willful misconduct, AVID will bear all reasonable costs associated with such
recall, market withdrawal or field correction (including but not limited to
costs associated with receiving and administering the recalled Drug Substance
and notification of the recall to those persons whom HALOZYME deems
appropriate).

      7. CHANGES IN PRODUCTION. AVID shall inform HALOZYME within fifteen (15)
calendar days of the result of any development that directly affects the
Production of the Bulk Drug Substance or changes to Bulk Drug Substance-specific
AVID SOPs. AVID shall give written notice to HALOZYME of any such changes, and
HALOZYME and AVID will review such development or changes in accordance with the
Quality Agreement. AVID shall assure that all such changes to the Bulk Drug
Substance-specific AVID SOPs are consistent with the Bulk Drug Substance Master
Plan unless the parties otherwise expressly agree in writing. AVID shall only
make changes to the Bulk Drug Substance Master Plan that are in accordance with
Section 2.2.

      8. CONFIDENTIALITY.

            8.1 Confidential Information. Subject in each case to Section 9.3.3,
during the term of this Agreement, and for a period of five (5) years following
the expiration or earlier termination hereof, each party shall maintain in
confidence all Confidential Information disclosed by the other party (including
all Confidential Information disclosed prior to the term of this Agreement
pursuant to a written confidentiality agreement between the parties), and shall
not use, grant the use of or disclose to any third party the Confidential
Information of the other


*** Confidential material redacted and submitted separately to the Commission



                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

party other than as expressly permitted hereby. Each party shall notify the
other promptly upon discovery of any unauthorized use or disclosure of the other
party's Confidential Information.

            8.2 Terms of this Agreement. Except as otherwise provided herein,
during the term of this Agreement and for a period of five (5) years thereafter,
neither party shall disclose any terms or conditions of this Agreement to any
third party without the prior consent of the other party. Notwithstanding the
foregoing, prior to execution of this Agreement, the parties have agreed in
writing upon the substance of information that can be used to describe the terms
of this transaction, and each party may disclose such information, as modified
by mutual agreement from time to time, without the other party's consent.

            8.3 Limitations on Disclosure. Each party shall limit the disclosure
of the Confidential Information of the other party and the terms of this
Agreement on a need-to-know basis to those directors, officers, employees,
consultants, legal and financial advisors, clinical investigators, contractors,
(sub)licensees, distributors or permitted assignees, to the extent such
disclosure is reasonably necessary in connection with such party's activities as
expressly authorized by this Agreement. To the extent that disclosure is
authorized by this Agreement, prior to disclosure, each party hereto shall
obtain agreement of any such Person to hold in confidence and not make use of
the Confidential Information for any purpose other than those permitted by this
Agreement.

            8.4 Permitted Disclosures. The confidentiality obligations contained
in this Section 8 shall not apply to the extent that such disclosure is
reasonably necessary in the following instances: (a) complying with an
applicable law, regulation of a governmental agency (including any regulatory or
governmental body or securities exchange) or order of a court of competent
jurisdiction, or responding to a subpoena, request for production of documents
or other lawful court process, (b) obtaining approval to test or market the Bulk
Drug Substance, (c) filing or prosecuting patents owned by the receiving party,
(d) prosecuting or defending litigation, and (e) disclosure to investment

equivalent in scope to those set forth in this Section 8, provided in each case
that the disclosing party shall provide written notice thereof to the other
party and reasonable opportunity to object to such disclosure or to request
confidential treatment thereof, if available. In the event such Agreement is
required to be disclosed under the laws of the Securities and Exchange
Commission ("SEC"), both parties shall use their reasonable best efforts, to the
extent allowable by the SEC, to redact the financial terms before any submission
to the SEC to protect the confidentiality of the financial terms contained
herein.

      9. INVENTIONS.

            9.1 Existing Intellectual Property.

                  9.1.1 Except as the parties may otherwise expressly agree in
writing, each party shall continue to own its existing patents, trademarks,
copyrights, trade secrets and other intellectual property, without conferring
any interests therein on the other party. Without limiting the generality of the
preceding sentence, HALOZYME shall retain all right, title and

*** Confidential material redacted and submitted separately to the Commission



                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

"Indemnitor") in writing of any claim, demand, action, or other proceeding in
respect of which the Indemnitee intends to claim such indemnification; provided,
however, that failure to provide such notice within a reasonable period of time
shall not relieve the Indemnitor of any of its obligations hereunder except to
the extent the Indemnitor is prejudiced by such failure. The Indemnitee shall
permit, and shall cause its Affiliates, and their respective directors,
officers, employees, subcontractors and agents to permit, the Indemnitor, at its
discretion, to settle any such action, claim or other matter, and the Indemnitee
agrees to the complete control of such defense or settlement by the Indemnitor.

impose any obligations on the Indemnitee in addition to those set forth herein,
in order for it to exercise such rights, without Indemnitee's prior written
consent, which shall not be unreasonably withheld or delayed. No such action,
claim or other matter shall be settled without the prior written consent of the
Indemnitor, which shall not be unreasonably withheld or delayed. The Indemnitee,

expense.

      13. INSURANCE. Each party shall maintain such insurance with respect to
the manufacture or distribution of the Bulk Drug Substance, as applicable to
each party, in such amounts as such party customarily maintains with respect to

such insurance for not less than one (1) year following the expiration date of
the last Bulk Drug Substance Produced under this Agreement.

14. TERM AND TERMINATION.

            14.1 Term. The term of this Agreement (the "Term") shall commence on
the Effective Date and shall, unless earlier terminated as provided herein,
continue for two (2) years. This Agreement shall, unless earlier terminated as
provided herein, thereafter renew automatically for additional one (1) year
terms. Either party may terminate this Agreement as of the end of the initial
term, or as of the end of any subsequent renewal term, by written notice to the
other party at least sixty (60) days prior to the renewal anniversary date.

            14.2 Termination for Breach. Either party may terminate this
Agreement upon the material breach of any provision of this Agreement by the
other party if such breach is not cured by the breaching party within,
forty-five (45) calendar days as to non-monetary breaches and thirty (30) days
as to monetary breaches, after receipt by the breaching party of written notice
of such default. In the event that the Production or sale of Bulk Drug Substance
is enjoined due to the alleged infringement by either party of the proprietary
rights of a third party, such occurrence shall be deemed a breach of this
Agreement by HALOZYME or AVID.

            14.3 Termination due to Regulatory or Infringement Issues. HALOZYME
may terminate this Agreement upon fifteen (15) days prior written notice to AVID
if (a) a Regulatory Authority withdraws marketing rights for, or otherwise
precludes the sale of, the Bulk Drug


*** Confidential material redacted and submitted separately to the Commission



                                 CONFIDENTIAL TREATMENT REQUESTED--REDACTED COPY

Substance (or any product for which the Bulk Drug Substance is an active
ingredient), or (b) HALOZYME becomes aware of the possible infringement of a
third party's intellectual property by the making, using, selling or importing
of the Bulk Drug Substance (or any product for which the Bulk Drug Substance is
an active ingredient).

            14.4 Additional Rights and Remedies. Subject to Section 11,
termination under this Section 14 shall be in addition to the other rights and
remedies of the terminating party. Termination of this Agreement for any reason
shall not relieve any party of any obligations accruing prior to such
termination.

            14.5 Payment on Termination. In the event of the termination of this
Agreement, HALOZYME shall pay the applicable Purchase Price for (i) all finished
Bulk Drug Substance, (ii) all work-in-process commenced by AVID, including
without limitation Incurred Materials (as defined below), except with respect to
clause (ii) in the event the termination is due to a breach by AVID and such
work-in-process cannot be delivered to HALOZYME or a new manufacturer for
completion, and (iii) all outside costs incurred under the Agreement up to the
date of termination, including but not limited to, raw materials, supplies,
travel and other expenses, provided such costs were reasonable and necessary to
complete the approved Manufacturing Schedule as set forth on Exhibit A or any
amendment thereto. AVID promptly shall deliver such finished Bulk Drug Substance
to HALOZYME in accordance with the Shipping Instructions. HALOZYME shall make
payments for all amounts due within thirty (30) calendar days from the date of
receipt by HALOZYME of the applicable invoice, pursuant to Section 5. As used in
this Section, "Incurred Materials" shall mean all raw materials, documentation,
and equipment purchased by AVID for use in the Production of Bulk Drug Substance
under this Agreement, but not yet billed to HALOZYME to the extent any such
materials, documentation or equipment can not be returned to its source for a
refund or used in manufacturing operations with AVID's other customers.

            In the event HALOZYME has caused a monetary default under the
Agreement, AVID shall not be obligated to ship any BDS or work-in-process until
all amounts due and owed as of the date of termination are paid in full.

            14.6 Survival. Termination, expiration, cancellation or abandonment
of this Agreement through any means or for any reason, except as set forth in
Section 14.1, shall be without prejudice to the rights and remedies of either
party with respect to any antecedent breach of any of the provisions of this
Agreement. The provisions of Sections 6, 8, 9, 11, 12, 14 and 15 hereof shall
survive expiration or termination of this Agreement.

            14.7 Files, Records, and HALOZYME property. Upon the expiration or
termination of this Agreement, at HALOZYME'S expense, AVID promptly shall make
available to HALOZYME copies of all manufacturing and process development
documents and records relating to Bulk Drug Substance not previously provided to
HALOZYME. Upon expiration or termination of this Agreement and the payment of
all amounts due to AVID by HALOZYME, AVID shall promptly make available to
HALOZYME all remaining units of the Master Cell Bank, Working Cell Bank and
Reference Standard. AVID will provide an inventory record for the Master Cell

inventory shall be AVID'S responsibility, and may be charged accordingly. Avid
shall store the originals or electronic copies of such documents and records
according to cGMPs in a safe and secure facility for at least one (1) year
following the expiration date or five (5) years from the date of manufacture if
there is no expiration date under this Agreement, and shall permit the FDA or
other Regulatory Authorities access to such documents and records to the extent
requested thereby. For a period of twelve (12) months following expiration or
termination of this Agreement, AVID shall make available to HALOZYME for review,

with normal operations); provided, however, that any such data, know-how,
technology, or information comprising AVID Know-How shall continue to be AVID
Confidential Information, but may be disclosed to such third party manufacturers
pursuant to written agreements containing confidentiality and non-use provisions
no less restrictive than those set forth herein, and (iii) HALOZYME shall pay to
AVID the fully burdened costs of assisting in any such technology transfer of
***, plus all out-of-pocket costs related thereto.

                  14.8.2 Transfer of Technology upon Breach by AVID. If,
following the uncured breach of a provision of this Agreement by AVID, HALOZYME
desires to (or desires a third party manufacturer (selected in good faith by
HALOZYME) to) process or manufacture the Bulk Drug Substance, then (i) AVID
grants to HALOZYME a worldwide, royalty-free, non-exclusive license under the
AVID Know-How and AVID Patent Rights solely to make and have made Bulk Drug
Substance, and (ii) AVID shall transfer to HALOZYME all data, know-how,

            Regulatory Affairs review.

      Rework

            Any additional steps taken to process a batch (other than
            re-inspection) to bring it into conformance with the specifications
            and which will not alter the safety, identity, strength, quality, or
            purity of the BDS beyond the established requirements. All rework
            must be documented per approved rework documentation requirements
            and appended to a deviation.

            to HALOZYME by AVID. The COA and COC will be generated upon
            completion of all testing requirements; it will contain the items
            tested, corresponding acceptance criteria, test results and raw test
            data. AVID will issue a COA and COC and release BDS to HALOZYME.
            HALOZYME is responsible for the approval and release of all bulk or
            packaged BDS after review of AVID' COA, COC and copies executed of
            batch records.

8.    Manufacturing and Packaging of BDS

              The manufacturing and packaging of BDS will be done according to
              the specific procedures and instructions mutually agreed by
              HALOZYME and AVID, and documented in the AVID BDS Specification
              Summary.

              The manufacturing and packaging of HALOZYME's BDS by AVID must
              comply with the specifications (provided that these do not
              significantly and adversely impact other processes at AVID)
              supplied by HALOZYME, with cGMPs, and with any other applicable
              regulatory requirements. AVID will prepare documentation for each
              batch of BDS manufactured, as agreed upon between HALOZYME and
              AVID. This complete documentation must be readily accessible for
              review and inspection by HALOZYME and regulatory authorities upon
              request.

              AVID will keep all in-process and finished BDS products,
              physically (and logically in the case of computer records and with
              appropriate segregation for all records related to the work)
              segregated (using AVID's warehouse shelf location procedures where
              each lot of material is appropriately labeled or tagged in the
              case of equipment) from all other materials not related to
              HALOZYME manufacturing. AVID must have line clearance procedures
              and appropriate changeover procedures that are implemented before
              and after manufacturing of BDS. Manufacturing equipment owned by
              HALOZYME Therapeutics must be clearly tagged as such and used only
              for the manufacturing of BDS.

              AVID will maintain the operation of the manufacturing facility in
              full compliance with all applicable cGMP, QSR, environmental,
              safety, health, fire, and similar regulations.

              All AVID personnel engaged in the manufacturing of BDS will have
              the education, training, and experience necessary to perform tasks
              related to the Commercial Supply Agreement in a professional and
              workmanlike manner.

              previously agreed to third parties and will be appropriately
              documented.

              AVID will provide to HALOZYME a COA, COC and copy of executed
              Batch History Record and any other associated inspection and
              testing documentation for each batch of BDS manufactured.

10.   Notification and Approval of Deviations and Non-Conformance

      10.1  Deviations

            AVID must notify HALOZYME within three (3) working days from the
            observation of a deviation from stated procedures or stated
            specifications. A deviation is defined as any out-of-specification
            result or any manufacturing, packaging, labeling or testing
            deviation that may affect the quality, safety or efficacy of BDS. If
            reprocessing, salvage, or rework is necessitated, prior written
            approval for initiating an NCMR must be obtained from HALOZYME. All
            deviations will be investigated and documented by AVID . This
            documentation will be retained as part of the batch documentation
            for the batch affected. When deemed necessary by HALOZYME, HALOZYME
            reserves the right to request additional or more in-depth
            investigation of the deviation by AVID. HALOZYME approval shall be
            obtained in writing (fax confirmation is acceptable) for any
            deviation impacting compendial status or regulatory filing.

      10.2  Non-Conformance

            AVID will notify HALOZYME within three (3) working day of materials,
            components, or products that do not meet specifications. Material or
            BDS not meeting established specifications are to be handled as
            non-conformances and documented as such, based on AVID' standard
            procedures. Actions taken to investigate the nonconformance and to
            justify the release of the lot of material must be documented.
            HALOZYME recognizes that a non-conformance in a raw material can
            result in an unplanned delay to the manufacturing schedule and that
            AVID will work to re-schedule into the first available manufacturing
            slot.

            The nonconformance document (i.e., NCMR) will be approved by both
            AVID and HALOZYME as, stated below. Any resulting corrective actions
            shall be followed through timely closure. Approval by the
            appropriate Quality Assurance functions are solicited and obtained
            via facsimile copy.

            Nonconformance                                Approval Requirements

            AVID will promptly initiate Corrective and Preventive Action
            programs to remedy deficiencies that caused the non-conformance, to
            the extent possible.

11.   Release and Shipment of BDS

      The final release of the BDS is the responsibility of HALOZYME. AVID has
      the responsibility to release the BDS to HALOZYME. AVID will not ship any
      of HALOZYME's BDS to any destination until the final release, [e.g.,
      issuance of a Certificate of Release (COR) provided by HALOZYME, which
      must be preceeded by the issuance of a Certificate of Analysis (COA) and
      Certificate of Compliance (COC) by AVID], unless prior approval in writing
      has been received from HALOZYME to perform such shipments and such
      requests do not conflict with any regulatory requirements imposed on AVID.

12.   Retained Samples of BDS

      AVID agrees to store retained samples under appropriate BDS label storage
      conditions and in a secure area for a period of time as defined by
      HALOZYME, but not to exceed 1 year after expiration, or 5 years after the

      updating of stability information to regulatory documents for the BDS is
      the responsibility of HALOZYME. All stability related activities under the
      responsibility of AVID shall be completed in a timely manner.

15.   Process Validation and Qualification of the BDS

      In accordance with mutual agreement of HALOZYME and AVID, the equipment,
      process, manufacturing, analytical, and control procedures (including
      cleaning procedures, where applicable) shall be qualified and/or validated
      as appropriate by AVID in the facility they intend to use for manufacture
      of HALOZYME's BDS using equipment and personnel AVID intends to employ to
      make HALOZYME's BDS.

      AVID is responsible for calibration and maintenance of equipment,
      processes, automated systems, and facilities.

      All related validation and qualification documents will be assembled in a
      validation summary report and provided to HALOZYME for review and
      approval. HALOZYME will retain a copy of the approved protocol and final
      report.

16.   Annual Product Review (APR)

      The Annual Product Review (APR) including all documents (SOPs, BPRs,
      Forms, etc.) will be prepared and reviewed according to AVID' policies and
      procedures for third party BDS. All APR activities, which are the
      responsibility of AVID, will be completed and documented as per a mutually
      agreed timeframe. The APR documentation completed by AVID will be provided
      to HALOZYME to review.

      HALOZYME and AVID will meet periodically to review quality issues related
      to the obligations and responsibilities as described in this SQA. During
      this periodic review, quality issues related to the past production by
      AVID will be reviewed. The information presented and discussed during this
      review meeting will be documented by AVID and approved by HALOZYME.

17.   Products Complaints

      HALOZYME will typically receive, communicate with the customers, and close
      all complaints related to the referenced products. AVID will provide any
      complaint information received (from customers in the marketplace or
      regulatory authorities) to HALOZYME within seven business (7) days unless
      a more urgent need is recognized, such as cases involving potential BDS
      tampering, or an adverse medical event. Upon the request by HALOZYME, AVID
      will investigate complaints, providing the complaints fall within areas of
      manufacturing conducted at AVID. AVID shall provide a written report on
      the results of the investigation to HALOZYME within thirty (30) working
      days, or sooner if agreed to by the parties. Depending on the complexity
      of the investigation, an extended investigation could result in additional
      time being required but AVID agrees to provide an interim report within
      said timeframe. HALOZYME will


  *** Confidential material redacted and submitted separately to the Commission



                CONFIDENTIAL TREATMENT REQUESTED - REDACTED COPY


      communicate with the customers or regulatory authorities the results of
      the complaint investigation, if necessary.

      HALOZYME shall provide complaint files to AVID onsite, or electronically
      within one (1) business day, if they are required during a FDA inspection.

18.   Returned Goods

      The handling of returned goods, if required, is the responsibility of
      HALOZYME.

19.   Recall of Marketed BDS Containing products

      In the event of recall, withdrawal, or field correction of a HALOZYME
      finished product for which the BDS is an active ingredient, or if any such
      product violates applicable laws, regulations, agreed upon specifications,
      or are deemed unacceptable for some other reason, whether or not such
      action is requested by any governmental agency, AVID shall cooperate with
      HALOZYME in conducting the necessary investigational activities only as
      they relate to manufacturing at AVID. AVID shall promptly notify HALOZYME
      if it becomes aware of any such recall, withdrawal, field correction,
      violation or other reason. If HALOZYME requests a complaint to be
      investigate by AVID and the results of that investigate indicate that the
      complaint is not related to any manufacturing issues at AVID, HALOZYME we
      reimburse AVID for all cost associated with the complaint investigation.

      If AVID is notified or becomes aware of a withdrawal of product or the
      initiation of a recall by one of AVID clients for whom AVID provides
      products or materials AVID will review whether any of the products or raw
      materials were used in the manufacturing of BDS and if found to have a
      common use, AVID will notify HALOZYME in writing immediately. HALOZYME
      will, with AVID cooperation, investigate the potential for impact on BDS
      and all products that used the affected batch(es) of BDS products.

20.   Audits and Inspections of Facilities and BDS

      AVID will notify HALOZYME of any inspections or actions by regulatory
      agencies or other enforcement bodies, which could potentially impact
      HALOZYME's BDS. AVID will provide HALOZYME with the results of all such
      regulatory audits in NMT seven (7) business days.

      HALOZYME reserves the right to audit AVID' facilities and systems, as they
      relate to the manufacture and control of HALOZYME BDS, with the exception
      of information and operations which constitute AVID' or other client trade
      secrets. These audits may be performed twice (2) per year as long as AVID
      is currently manufacturing for HALOZYME. These audits can be arranged with
      AVID's Quality Assurance department at mutually convenient times. Each
      audit visit will be limited to two (2) auditors from HALOZYME. After
      successful completion of a United States Food and Drug Administration
      Pre-Approval Inspection for EnhanzeSC(TM) and the successful completion of
      a United States or California Food and Drug Administration or a Notified

      Body Inspection for Quality System Requirements or International Standards
      Organization requirements for Cumulase(TM), HALOZYME audits may not be
      performed more than once per year. The number of auditors from HALOZYME
      will be limited to two (2) per audit.

      NOTE: The once per year limitation will be waived if the audit to be
      performed is "for cause". "For cause" is limited to review of adverse
      regulatory agency observations or re-call of BDS due to manufacturing
      issues at AVID.

      The right to audit will also cover any subcontractors utilized by AVID.
      HALOZYME reserves the right to be on-site as a non-contributing
      participant at AVID during the manufacture of HALOZYME's BDS, and during
      the inspection of HALOZYME's BDS by any regulatory agencies. It is
      understood by HALOZYME, that the presence of any HALOZYME employees during
      any regulatory inspections by the FDA, California FDA or EMEA are
      non-participants and must not contribute in any way during the course of
      the inspection or AVID reserves the right to excuse them from the audit.
      AVID shall respond to, and forward all responses to observations,
      generated during HALOZYME's audit, within thirty (30) business days from
      their issuance. AVID shall comply with all applicable Federal, State, and
      Local laws and regulations.

      AVID warrants that it will not employ persons debarred pursuant to
      sections 306(a) and (b) of the Federal Food, Drug, and Cosmetic Act 21
      U.S.C. 335(a) and (b).

21.   Re-inspection

      A re-inspection is performed under conditions where rHuPH20 API quality
      requires re-verification. The re-inspection work shall be approved and
      performed by AVID, according to established procedures. The re-inspection
      work must be documented to state reasons, justification, directions for,
      and results of re-inspection.

22.   Reprocessing and Rework

      Reprocessing and rework activity can only be performed per mutual written
      agreement by AVID and HALOZYME. Reprocessing and rework directions must be
      established to define the process. If BDS has been filed as a drug
      substance in an NDA or equivalent, reprocessing parameters must be
      developed and submitted to the HALOZYME for regulatory submission, prior
      to approval. Reprocessing or rework of material or BDS must be documented
      to state reason and justification for reprocessing.

23.   Shipping Instructions

      AVID will control and coordinate all shipping activity as specified by
      HALOZYME. HALOZYME is responsible for ensuring that all packaging, storage
      conditions and that the freight or shipping company conforms to their
      requirements.
