     transfer   price  of  Product   available  to  VaxGen  from  other  sources
     (including,  without  limitation,  its own production  facilities).  If the
     Parties fail to extend (with mutually agreed  modifications)  their respect
     supply and purchase  obligations  hereunder,  the Agreement shall terminate
     180 days after the last day of the Initial Production Period.

4.4  Forecasts and Supply Orders in excess of Maximum Supply Obligations. In the

     million Units of Product in any calendar  year,  the Parties shall meet and
     confer  in good  faith in order to  discuss  an  increase  capacity  at the
     Facility.

4.5  Timely  Manufacturing  of the  Product.  Celltrion  shall use  commercially
     reasonable  efforts to  manufacture  and supply  VaxGen  with  Product in a
     timely manner, in accordance with the Supply Orders and the Agreement.  The
     Parties understand that commercial  production from the Facility ("Launch")
     is anticipated to commence on or before December 31, 2005.  Notwithstanding
     anything in this  Agreement to the contrary,  in the event that: (i) Launch
     is delayed by more than 12 months other than by virtue of the negligence or
     intentional   misconduct  of  VaxGen,  (ii)  having  completed   sufficient
     technology transfer and performed successful  qualification runs, licensure
     of the  Product is delayed by more than six months  other than by virtue of
     the negligence or intentional  misconduct of VaxGen, (iii) licensure of the
     Product having occurred, continuous commercial production of Product at the
     Facility is interrupted  by more than 60 consecutive  days or for more than
     90 days in any 12 month  period other than by virtue of the  negligence  or
     intentional  misconduct of VaxGen, VaxGen shall have the right to commit to
     the  production  of  Product  at  a  different  site  and  the  rights  and
     obligations of the Parties hereunder (including,  without limitation, those
     under Sections 3.1 and 4.3) shall be equitably adjusted accordingly.

     FOB at the  Facility.  VaxGen shall have an  authorized  person  certify in
     writing the condition of the delivered  Product promptly  following receipt
     and shall  thereafter  store all received  Product in  accordance  with the
     Storage Specifications. Title and risk of loss of the Product shall pass to
     VaxGen  upon   delivery   from  the   Facility   to   VaxGen's   designated
     representative.

     Product from  Celltrion,  VaxGen shall  perform the agreed upon  Acceptance
     Criteria tests to determine acceptability of such shipment and shall notify
     Celltrion  in  writing  of  any  claim  relating  to any  specific  alleged
     non-conformity with the Acceptance Criteria.  VaxGen may reject any Product
     that fails to meet the Acceptance  Criteria ("Rejected  Material").  In the
     event Celltrion does not receive any such notice within such 60-day period,
     the  Product  received  shall  conclusively  be  deemed  to  have  met  the
     Acceptance Criteria. If, due to circumstances beyond its control, VaxGen is
     unable to  complete  its  evaluation  of Product for  acceptance  with such
     60-day  period,  VaxGen will  immediately  provide  Celltrion  with written
     notification  of  this  fact  and  provide  a  reasonably  revised  date of
     notification, which shall thereafter be binding on the Parties.

5.3  Defective Shipments.  If any Product supplied by Celltrion materially fails
     to meet the  Acceptance  Criteria  or  fails  to have at  least  2/3 of the
     established shelf life remaining at the time of delivery, the Parties shall
     meet and  Celltrion  shall,  at VaxGen's  option,  either use  commercially
     reasonable  efforts  to  replace,  at no cost for  VaxGen,  such  defective
     Product as promptly as practical,  or issue a refund therefor. In the event
     that the parties cannot  mutually agree as to whether Product fails to meet
     the Acceptance  Criteria,  then the Parties shall refer the matter,  to the
     extent of their disagreement, to the dispute resolution procedure described
     below.

5.4  Release  Certificate.  Celltrion shall provide to VaxGen with each delivery
     of  Product  a  Release  Certificate,  a  Certificate  of  Analysis  and  a
     Certificate of Compliance (all as more particularly  specified in a Quality
     Assurance  Agreement to be entered into between VaxGen and Celltrion within
     a  reasonable  time prior to Launch)  signed by a  responsible  person duly
     authorized  by Celltrion  to certify the quality of the Product  delivered.
     Such Release  Certificate  shall, inter alia, state that the results of the
     agreed  upon  testing   procedures  are  in  compliance  with  the  Product
     Specifications  as  well  as  any  additional  applicable  requirements  of
     Regulatory  Authorities.  Without limiting the foregoing,  unless expressly
     agreed by the Parties all Product  supplied by  Celltrion  hereunder  shall
     meet all release  criteria  established  by the FDA or EMEA with respect to
     such Product.

5.5  Production  Records.  Celltrion  shall  maintain  records  related  to  its
     manufacture and handling of Product in accordance with the applicable rules
     and  regulations  applicable to the Product and conditions of its licensure
     (including  applicable  rules of the FDA, EMEA ICH and any other applicable
     regulatory  requirements for record retention),  for the longer of (i) five
     years after the date of manufacture of each batch of Product,  and (ii) the
     period  required by applicable  law.  Celltrion  shall notify VaxGen of any
     intent to  destroy or dispose  of  records  related to the  manufacture  or
     handling of Product and allow VaxGen an  opportunity to secure said records
     for additional storage periods in accordance with the written procedures of
     VaxGen or its designee. Upon VaxGen's request with no fewer than five days'
     prior notice, and at VaxGen's sole expense,  Celltrion shell send to VaxGen
     copies of the relevant documents and/or permit VaxGen and/or an independent
     auditor selected by VaxGen to have access to such records from time to time
     during ordinary  business hours to verify compliance by Celltrion with such
     rules and  regulations;  provided,  however,  that  VaxGen's  inspection or
     access shall not unreasonably  interfere with Celltrion's  operations.  The
     provisions  set forth in this  section  shall  survive  termination  of the
     Agreement for the longer of (i) five years after the date of manufacture of
     each batch of Product, and (ii) the period required by applicable law.

ARTICLE 6 PRODUCT SHORTAGE

Celltrion shall use commercially  reasonable  efforts to satisfy VaxGen's orders
for Product in a timely  fashion.  However,  Celltrion shall not be liable for a
failure  to supply  Product  in the event of (but only to the  extent)  of Force
Majeure as provided  hereinbelow.  Celltrion shall immediately  notify VaxGen of
any potential or anticipated  shortfall in the manufacturing of the Product that
may  adversely  affect  the  delivery  of Product in  accordance  with  VaxGen's
forecast  requirements  and pending Supply  Orders.  Without  limiting  VaxGen's
rights under  Section 4.5,  above,  if Celltrion is unable,  for any reason,  to
supply  VaxGen the full amount of Product to which VaxGen is entitled  hereunder
in  accordance  with  the  delivery  schedule  established  in a  Supply  Order,
Celltrion  shall notify VaxGen of such  situation as soon as practical and shall
allocate to VaxGen all available  capacity at the Facility available in order to
minimize the shortfall in production of the Product.

ARTICLE 7 PAYMENTS

7.1  Transfer  Price.  VaxGen shall pay to Celltrion,  for all Product  supplied
     hereunder,  a transfer price (the "Purchase Price") equal to the lesser of:
     (i) [*](1) percent of Celltrion's  Fully  Burdened  Manufacturing  Cost, or
     (ii)  the  "prevailing  market  rate"  for  the  contract   manufacture  of
     recombinant  products comparable in complexity to AIDSVAX,  manufactured in
     comparable  quantities  and on a  delivery  schedule  and  other  terms and
     conditions  comparable to those set forth herein,  calculated as a function
     of the Fully Burdened Manufacturing Cost of such comparable products. On or
     before  November 1 of each  calendar  year during the term of the Agreement
     following  the date of Launch,  the Parties  shall in good  faith,  for the
     purposes of deciding the "prevailing  market rate",  approach no fewer than
     three pharmaceutical  contract  manufacturers  throughout the world who are
     not  Affiliates of Genentech or VaxGen and who are qualified to manufacture
     AIDSVAX and who have available capacity  sufficient to supply the projected
     requirements  of  VaxGen  hereunder  for  the  forthcoming  calendar  year.
     Notwithstanding  anything to the contrary,  prices  charged by Celltrion to
     its customers for products other than AIDSVAX or any  introductory  product
     can be used as one of the aforementioned  three prices. As a result of such
     survey,  or an equivalent  survey  conducted by a third party acceptable to
     the Parties,  the Parties shall agree upon the then-prevailing  market rate
     for such  manufacture  which,  if less than [*](1)  percent of  Celltrion's
     Fully Burdened Manufacturing Cost, shall be deemed to be the Purchase Price
     for the forthcoming  calendar year. If the Parties are unable to agree upon
     such  prevailing  rate on or before  December 15 of an annual review cycle,
     the matter shall be referred to  resolution by  arbitration  as provided in
     Section  18.4,  below.  In such case,  the  transfer  price shall be [*](1)
     percent of  Celltrion's  Fully  Burdened  Manufacturing  Cost  until  final
     resolution  by  arbitration,  which shall be adjusted  after  resolution by
     arbitration.

7.2  Payment.  Celltrion  shall  invoice  VaxGen for the Purchase  Price of each
     shipment of Product upon  delivery of the same as specified  herein,  which
     invoice  shall  include   information   sufficient  to  verify  Celltrion's
     calculation of the Fully Burdened Cost of Manufacture on which such invoice
     is based.  VaxGen shall pay to  Celltrion  the amount due within 45 days of
     the date of the corresponding  invoice.  Payments shall be remitted by wire
     transfer in the  invoiced  currency to a bank account to be  designated  in
     writing from time to time by Celltrion.  The currency of such invoice shall
     be Korean Won. At an appropriate time, the board of directors of Celltrion,
     in  consultation  with  VaxGen,  shall  establish  appropriate   accounting
     procedures to track and document the Fully  Burdened Cost of Manufacture on
     a batch-by-batch  or  shipment-by-shipment  basis. In calculating the Fully
     Burdened  Manufacturing  Cost on a batch-by-batch  or  shipment-by-shipment
     basis,  up to and  including ten percent (10%) of the failure rate shall be
     taken into account so that the costs of such  failure  shall be included in
     the Fully Burdened Manufacturing Cost. Any failure rate up to and including
     ten percent (10%) shall be treated as ten percent (10%) for the purposes of
     the Fully Burdened  Manufacturing  Cost. In the event that the failure rate
     exceeds ten percent (10%) but is less than  twenty-five  percent (25%), the
     costs associated with failed  production in excess of ten percent 10% shall
     be  borne by  Celltrion  and  VaxGen.  In the  event  the  failure  rate is
     twenty-five  percent (25%) or more, the Parties shall consult in good faith
     as to how the failure rate can be lowered.

7.3  Take or Pay. On or before  January 30 of each calendar  year  commencing in
     the calendar year following the year in which Launch occurred, VaxGen shall
     notify  Celltrion of the total number of Units of Product ordered by VaxGen
     during the preceding  calendar year (the "Total Annual Orders" for the year
     in  question).  Such total shall not be reduced by the  amount,  if any, of
     defective  Product supplied by Celltrion or other Product ordered by VaxGen
     but not delivered for any reason other than fault on the part of VaxGen. If
     Celltrion  does not object to the Total Annual Orders  calculated by VaxGen
     within 15 days after  receipt  thereof  from  VaxGen,  such number shall be
     conclusively  deemed  to be  correct.  If  Celltrion  does so  object,  the
     objection shall be subject to dispute  resolution as provided  hereinbelow;
     provided,  however,  that the figure provided by VaxGen shall be binding on
     the Parties  absent mutual  agreement or a contrary  finding as a result of
     resort to the dispute resolution  procedures  provided  hereinbelow.  Until
     such time as the exact Total Annual Orders is resolved by arbitration,  the
     figure provided by VaxGen shall be considered as the tentative Total Annual
     Orders for calculation of payment by VaxGen to Celltrion.

     If the Total Annual Orders for any calendar year total less than 87 million
     Units of Product  (pro rated for partial  calendar  years),  then within 15
     days after  notification of Celltrion  pursuant to this Section 7.3, VaxGen
     shall pay to Celltrion an amount calculated according to the formula:

                              X = ((A-B) x (Q)) + Z

     wherein X is the amount due to Celltrion denominated in Korean Won, A is 87
     million  Units of Product,  B is

(1) [*] denotes confidential treatment requested. A complete version of this
exhibit has been filed separately with the Securities and Exchange Commission.

<PAGE>

     the Total Annual Orders for the calendar year at issue denominated in Units
     of Product,  Q is the Average Gross Profit for Product during the preceding
     calendar year and Z represents  the total  unreimbursed  fixed costs of the
     Facility directly  attributable to the amount of Product  calculated by the
     formula  (A-B)x(Q).  If no production  of Product  occurred at the Facility
     during the preceding calendar year, then Q shall be deemed to be 30 percent
     of the Purchase Price of the most recent batch of Product supplied from the
     Facility as provided hereinabove.

ARTICLE 8 IMPROVEMENTS

8.1  Product  Improvements.  All improvements or modifications made by Celltrion
     to the Product or to the process used by Celltrion for the  manufacture  of

     achieved as a result of process  improvements or modifications  made solely
     by Celltrion  shall be shared by Celltrion and VaxGen at the rate of 80:20,
     respectively,  during the first full year after the improvement is realized
     and 50:50 thereafter.

ARTICLE 9 CHANGES TO THE PRODUCT

9.1  Required by Celltrion for Regulatory Purposes.  VaxGen will promptly notify
     Celltrion  of any  modifications  to the Product  Specifications  or to the

ART1CLE 11 QUALITY DISPUTES

11.1 Product Quality Disputes.  If VaxGen rejects any Product and if the Parties
     have not agreed  mutually on a remedy as per Section 5.3 of the  Agreement,
     the Parties,  through a Coordinating  Committee to be formed by the Parties
     (the  "Coordinating  Committee")  shall timely  consult with each other and
     attempt to resolve the discrepancies in good faith.

     If the Parties cannot resolve the  discrepancies in a timely manner through
     the Coordinating  Committee after notification  thereof to Celltrion,  they
     shall  promptly  nominate an  independent  expert or  laboratory,  mutually
     agreed upon by the  Parties,  which shall carry out an  investigation  with
     respect  to such  Product  as may be  jointly  agreed  upon by  VaxGen  and
     Celltrion and at the Parties' joint expense.  The results  obtained by said
     laboratory  or expert  shall be binding on the Parties for  purposes of the
     Agreement.

<PAGE>

     If the  results  conclude  that the  Product  conformed  to the  Acceptance
     Criteria, VaxGen will reimburse Celltrion for its share of the amounts paid
     to the expert  laboratory for such  investigation.  If the results conclude
     that the Product  does not conform to the  Acceptance  Criteria,  Celltrion
     shall  reimburse  VaxGen  for its share of  amounts  paid to the  expert or
     laboratory.

     Until such time as the expert or laboratory  determines whether the Product
     conforms  to the  Acceptance  Criteria,  VaxGen  may  withhold  payment  to
     Celltrion of any amounts due in respect of the subject  Supply  Orders.  In
     the  event  that  the  subject  Product  is  determined  to be  conforming,
     Celltrion  shall be entitled to prompt  payment of all  amounts  due,  plus
     interest thereon accrued at a rate of LIBOR plus two percent.

11.2 Remedy for Non-Conforming  Product. If VaxGen rejects any Product and if it
     is determined by the expert or  laboratory  identified  pursuant to Section
     11.1,  above,  that  such  Product  did not or  would  not  conform  to the
     Acceptance Criteria,  Celltrion shall, at VaxGen's option, reimburse VaxGen
     the amount paid by VaxGen for the rejected  Product plus  interest  thereon
     accrued at a rate of LIBOR plus two percent or produced replacement Product
     on a mutually agreed schedule.

ARTICLE 12 DECLARATION

                                    Exhibit A

Technical Description of AIDSVAX(TM) "Product"

Recombinant  gp120 (rgp120) is the recombinant form of an envelope  glycoprotein
of human  immunodeficiency  virus 1  (HIV-1).  The  rgp120  glycoprotein  has an
apparent molecular mass of approximately  120,000 daltons.  Approximately 50% of
the molecular mass is accounted for by extensive  glycosylation  of the protein.
The  rgp120  glycoproteins  used in the  production  of  AIDSVAX(TM)  are highly
purified mixtures produced by recombinant DNA technology using a Chinese Hamster
Ovary (CHO) cell line. The CHO cell-secreted rgp120 sequences are recovered from
the harvested cell culture fluid and purified according to standard  techniques,
including immunoaffinity chromatography.

The CHO cells express the sequences of MN rgp120, GNE8 rgp120 or A244 rgp120. MN
rgp120 is a 502 amino acid derivative of the envelope  glycoprotein  gp120 found
in the MN  (Subtype  B)  isolate  of HIV-1.  GNE8  rgp120  is a 485  amino  acid
derivative  of the gp120 found in the GNE8  (Subtype  B) isolate of HIV-1.  A244
rgp120 is a 503 amino acid derivative of the gp120 found in the A244 (Subtype E)
isolate of HIV-1.  The molecules  bind to CD4 with high affinity and are heavily
glycosylated.  Analysis of the sequence data  demonstrated  the predicted  amino
acid  sequence of GNE8 differed by 15% from MN and A244 differed by 30% from MN.
Each  lot of  product  must  comply  with  FDA  and  VaxGen  specifications  for
sterility, identity, purity, potency and safety.Exhibit 10.11.1

                                                                    CONFIDENTIAL

                   Additional Tasks to be Performed by Artisan

A.    Additional Tasks to be Performed by Artisan

Standard Cell [***] Verification

      Artisan and National shall agree in writing to use a specific version of a
[***] Check ("DRC") program and runset for the standard cell deliverables listed
in Exhibit 3 below before Artisan commences work hereunder.

      Artisan will [***] the standard cells to the latest [***] runsets and
provide the complete set of standard cells (CDL and GDSII) to National for
physical verification. Within [***] of being provided the GDSII file, National
will: (1) run [***] on the GDSII file using the agreed upon version of the
DRC/LVS program and runset, and (2) report any DRC/LVS run errors, if any, to
Artisan. If National identifies DRC/LVS run errors, then Artisan will work to
correct such errors and redeliver the GDSII file to be retested by National
(Artisan and National will repeat this process until such errors are corrected).
If National reports to Artisan that there are no DRC/LVS run errors or does not
timely report to Artisan, Artisan will run final verification, package and
release the updated standard cell library. The released library will be to
ARTI-EDA-P3.0, including the design for test options.

Memory Generator [***] Verification

      Artisan will [***] the memory leaf cells and memory generators to the
latest [***] runsets and provide the complete set of memory leaf cells to
National for physical verification. Within [***] of being provided the GDSII
file, National will: (1) run [***] on the leaf cells using the agreed upon
version of the DRC/LVS program and runset, and (2) report any DRC/LVS run
errors, if any, to Artisan. If National identifies DRC/LVS run errors, then
Artisan will work to correct such errors and redeliver the leaf cells to be
retested by National (Artisan and National will repeat this process until such
errors are corrected). If National reports to Artisan that there are no DRC/LVS
run errors or does not timely report to Artisan, Artisan will run final
verification, package and release the updated leaf cells.

      Artisan and Licensee shall agree in writing to use a specific version of a
[***] program and runset for validating the memory generators listed in Exhibit
3 below before Artisan commences work hereunder. Artisan will provide Licensee
with Artisan's quality assurance instance list. At least [***] prior to the
intended delivery date, Licensee may provide Artisan a list of up to [***]
additional instances (the "Instances") that it wishes to subject to DRC/LVS
validation.

      Artisan will [***] the memory instances to the latest [***] runsets and
provide the complete set of memory instances to National for physical
verification. Within [***] of being provided the GDSII file, National will: (1)
run [***] on the memory instances using the agreed upon version of the DRC/LVS
program and runset, and (2) report any DRC/LVS run errors, if any, to Artisan.
If National identifies

DRC/LVS run errors, then Artisan will work to correct such errors and redeliver
the memory instances to be retested by National (Artisan and National will
repeat this process until such errors are corrected). If National reports to
Artisan that there are no DRC/LVS run errors or does not timely report to
Artisan, Artisan will run final verification, package and release the updated
memory instances and generator. The released library will be to ARTI-EDA-P3.0,
including the design for test options.

Note: No 'false' DRC/LVS errors will be corrected in the layouts. National will
      be responsible for the elimination of any 'false' errors that are
      uncovered.

      LVS will be run in hierarchical mode.

      LVS transistor tolerance will be set to .1%. Memory generators may have to
output an additional file to achieve this.
