SECTION H - SPECIAL CONTRACT REQUIREMENTS


ARTICLE H.1.  REIMBURSEMENT  OF COSTS FOR  INDEPENDENT  RESEARCH AND DEVELOPMENT
              PROJECTS

The primary purpose of the Public Health Service (PHS) is to support and advance
independent research within the scientific  community.  This support is provided
in the form of contracts and grants  totaling  approximately  7 billion  dollars
annually.  PHS has  established  effective,  time  tested  and  well  recognized
procedures for stimulating and supporting this independent research by selecting
from multitudes of applications  those research  projects most worthy of support
within the  constraints of its  appropriations.  The  reimbursement  through the
indirect  cost  mechanism  of  independent  research and  development  costs not
incidental to product improvement would circumvent this competitive process.

To ensure that all research and development  projects  receive similar and equal
consideration,  all organizations may compete for direct  funding of independent
research and  devdopment projects they consider  worthy of support by submitting
those projects to the appropriate Public Health Service grant office for review.
Since these projects may be submitted for direct funding,  the Contractor agrees
that no costs for any independent  research and development  project,  including
all applicable indirect costs, will be claimed under this contract.

Contracting Officer.


ARTICLE H.3. HUMAN MATERIALS 

It is understood that the acquisition and supply of all human specimen  material

      this modification.

               the Contractor's laboratory within four hours of notification for
               pick-up.  Specimens shall be protected from temperature  extremes
               by use of  insulated  containers  or  other  acceptable  means as
               needed.  A portable  liquid  nitrogen  container for transport of
               frozen  cells or tumor  specimens  shall also be  required.  Only
               specimens provided by or approved by the Project Officer shall be
               accepted for processing and storage by the Contractor.

         4)    The Contractor  shall be responsible for recording and monitoring
               the  location  of all  specimens  that are being sent or received
               through  use of a log book of all  requests  and  specimens.  The
               Contractor  shall be  responsible  for  monitoring,  shipping and
               receipt of specimens to minimize  delay or loss. If a specimen is
               not  received  within  four  hours  of  expected  delivery,   the
               Contractor  shall  inform the Project  Officer by  telephone.  An
               after-hours  telephone  number of the  Contractor's  staff member
               shall be  available  to  assist in this  follow-up  and the staff
               member shall be available at that number. The Contractor shall be
               responsible  for  immediately  tracing the location of delinquent
               specimens not received when  expected.  All specimens that are of
               questionable  research  value  shall  be  noted  and the  Project
               Officer immediately notified by telephone, as well as in writing,
               providing  identifying  names  or  numbers,  quantity,  place  of
               origin, a concise  narrative  description of the event,  etc., so
               that  appropriate  action can be initiated.  The Contractor shall
               designate a specific individual to be responsible for after-hours
               specimen processing and name an alternate to act when the primary
               person is not available.

         5)    The Contractor shall maintain a repository of biologic  specimens
               for the Epidemiology and Biostatistics  Program (EBP). This shall
               include frozen serum,  plasma,  urine, tumor tissue, tumor tissue
               extracts, whole red blood cells, separated and frozen white blood
               cells, or fractions of white blood cell populations,  bone marrow
               cells,  body  fluids,   lymphoblastoid  cell  lines,  DNA,  stool
               specimens or smears or slides,  pathology  paraffin  blocks,  and
               other types of specimens  as  specified  by the Project  Officer.

                                                       Contract No. N02-CP-71001

         6)    All specimens will be submitted to the Contractor, accompanied by
               written  identification  of  the  specimen  source,  using  forms
               supplied  by the  Project  Officer.  Specimens  from  members  of
               NCI-associated  families  will be submitted  with a unique Family
               Studies  identification  number to insure  compatibility with NCI
               laboratory  computer  data bases.  Specimens  shall be assigned a
               unique code number which shall be the only  identification of the
               specimen in future laboratory  processing,  dispersal,  etc. This
               code  number  shall   comply  with  the  format  and   convention
               established  by the NCI  Project  Officer.  The name of the donor
               shall not be used in labeling of specimens  or in  correspondence
               concerning  the specimen by laboratory  personnel.  Such labeling
               shall  uniquely  identify  each  vial  of each  specimen  and the
               quality of that  individual  vial will be recorded and updated as
               needed in the NCI-developed computer system.

         7)    The  Contractor  shall provide and train primary and backup staff
               in the  operation of a  computerized  record system for specimens
               which has been  developed and  furnished by the Project  Officer.
               Using this  system,  the  laboratory  shall  keep  records of all
               manipulation  on all specimens and accurately  enter data on each
               specimen.  The data  shall  include  but not be  limited  to vial
               identification  number,  study  ID,  material  type and  material
               description,  volume,  weight  or  cell  concentration,   freezer
               location, subject ID, crisis events, data received, specimen vial
               quality,  etc.  Data  shall  be  entered  into the  system,  with
               attention to extreme  accuracy,  within 48 hours of receipt or as
               specified by the NCI Project  Officer.  The  Contractor  shall be
               responsible  for  extracting  this  information  from either data
               forms or floppy disks which will be transmitted with the samples.
               The  Contractor  shall also use this  system to monitor and track
               all  activities  related to specimens.  The Project  Officer will
               supply computer support for generating management reports for the
               Contractor on a regular basis.

         8)    The Contractor  shall prepare a variety of specimens for storage.
               Specifically,  white  blood cell  separation,  fractionation  and
               viable cryopreservation,  red blood cell cryopreservation,  serum
               separation  and storage of aliquots of 0.5 ml, plasma  separation
               and storage, tumor tissue freezing, tumor tissue extracts, urine,
               serum, or blood fluid lyophilization,  freezing and/or extraction
               of stool  specimens and other  techniques as required.  Specimens
               shall be stored in containers  impervious to entry of CO2 so that
               they can be shipped on dry ice. In order to ensure the  viability
               of valuable  specimens,  the Contractor shall be prepared to have
               appropriate  personnel  travel to a  contract  site,  foreign  or
               domestic, to train local staff on optimal techniques for freezing
               viable material.

         9)    Freezers  shall  be  equipped  with  a  stylus  recording  system
               indicating  consistency of temperature which shall be reviewed an
               a  scheduled   basis  each  day  at  specified   times.   Freezer
               malfunctions  must give warning by means of an alarm system.  The
               Contractor must provide a central alarm system monitored 24-hours
               a day, 365 days a year. A switch-operated  electric  generator of
               appropriate wattage for these particular freezers shall be hooked
               up and be  maintained  on standby  in the event of a major  power
               outage.  Liquid  nitrogen  freezers must have  automatic  filling
               mechanisms  drawing  on  a  constant  central  source  of  liquid
               nitrogen with emergency back-up.  All unplanned  defrostings must
               be logged, giving date and times during which defrostings were in
               effect and temperature reached, and reported by telephone as soon
               as possible  to the Project  Officer.  The  circumstances  of the
               defrosting  shall be reported  immediately to the Project Officer
               in writing, giving full particulars.

         10)   The laboratory  shall keep clear records of all  manipulations on
               all specimens and carefully document specimen type, volume,  cell
               concentration, source, "crisis events", etc. for each sample. The
               exact freezer location shall be known for each specimen and shall
               be kept in a master log which is easy to understand.  Information
               shall be supplied  routinely to the NCI Project  Officer on forms
               designed  and  supplied  by NCI in  conjunction  with  laboratory
               personnel.  Ihese records shall  include  number of vials,  exact
               location of vials and specimen type. The Contractor shall conduct
               a complete  inventory of all stored specimens on an annual basis.
               Thorough quality control  protocols must be designed,  documented
               and approved by the NCI Project Officer.  These protocols must be
               rigorously  implemented  in the conduct of the  inventories.  The
               results  of each  inventory  shall be  documented  in the  Annual
               Technical Progress Report.

         11)   The  Contractor  shall  respond  only  to  written  requests  for
               biological specimens from collaborating investigators, which have
               been approved by the NCI Project Officer or his/her  designee(s).
               Specimens shall not be sent to any investigator without a written
               request from the NCI Project  Officer or his/her  designee(s).  A
               copy   of   this   written   request   and   Contractor-generated
               correspondence  shall  be sent to the NCI  Project  Officer.  All
               written  requests for specimen  distribution  shall be acted upon
               within four working days of receipt,  unless  permission to delay
               such action is obtained from the Project Officer.

               The Contractor shall not supply the outside collaborator with any
               information  concerning the biological  specimens other than code
               number, specimen type or other infomrmation essential to specimen
               processing.  Requests  for  identificatian  of the  patient,  the
               diagnosis,  demographic data or other such  information  shall be
               referred to the NCI Project Officer.

               The  Contractor  shall  never  send  out  the  last  vial  from a
               particular  specimen  without  explicit  authorization  from  the
               Project Officer.

                                                       Contract No. N02-CP-71001


               The  Contractor  shall prepare  specimens  for  shipment,  supply
               shipping  containers  appropriate  to maintain  specimens  in the
               proper  state  (cool,   frozen,  deep  frozen,   etc.)  and  make
               arrangements  through  commercial air freight companies and other
               carriers   to   send   biologic    specimens   to   collaborating
               investigators  in an  expeditious  (e.g.,  overnight or same day)
               fashion.   For  immunologic  or  genetic  typing   studies,   the
               Contractor shall prepare  specimens for delivery to the local HLA
               typing  laboratory  or immune  function  laboratory in a suitable
               form. The local in-house delivery service shall be used for these
               particular specimens to ensure expeditious delivery under optimum
               conditions.  In some cases, commercial freight companies shall be
               used in overnight shipments to investigators in other cities. The
               Contractor  shall be  responsible  for  notifying  the  receiving
               laboratory of the  specimens'  shipment and  anticipated  arrival
               time to insure  that the  receiving  laboratory  is  prepared  to
               receive the specimens. All specimens for both immunologic testing
               and HLA typing and serum or other type storage shall be processed
               by the Contractor. Peripheral blood cells shall be aliquotted for
               storage in suitable  quantities  for  subsequent  testing.  Other
               specimens,  such as red blood cells, plasma, serum, urine, stool,
               tumor  tissue,  and body fluids shall be processed for storage in
               appropriate aliquots.

         12)   The  Contractor  shall  be  prepared  to  process  the  following
               quantities of materials:

                                                       Typical Total
                             Max Daily      Vials      Monthly Volume
     Material                  /person     /person   (Individual Samples)
----------------------------------------------------------------------------
WBC Cryopreservation         1,500 cc (60)      5      15,000 cc (250)  
Plasma/serum aliquotting     2,500 cc (60)    6-12     25,000 cc (250)  
RBC cryopreservation           250 cc (25)      5         750 cc (75)      
Pelleted lymphocytes           150 cc (15)      4         600 cc (60)      
Buffy coat preps               200 cc (20)      2         300 cc (30)

               Although   these  are  ESTIMATES  of  the  amount  of  work,  the
               Contractor must be able to accommodate highly variable amounts of
               processing  and  possible  changes in specimen  types and volumes
               depending on the new studies  evolving  during the contract (e.g.
               increased  processing of buccal swabs and rinses;  gastric juice;
               feces;   urine,   etc.).  All   prioritization  of  the  specimen
               processing  is  determined  by the NCI Project  Officer.  Not all
               maximal quantities of each material will arrive on a given day.

               For  this  aspect  of  the  contract,   it  is  anticipated  that
               technicians  shall  be  available  at least  one day per  weekend
               through the entire  period of this  contract  (the weekend  blood
               samples will be less than 200 ml and from less than five donors).

                                                       Contract No. N02-CP-71001

         13)   The Contractor shall handle international shipments of biological
               specimens  (blood  components,  urine,  gastric juice, and biopsy
               specimens)  and  clearance  of these  shipments  through U.S. and
               foreign   customs.   The  Contractor   must  provide  a  separate
               shipping/customs  agent to coordinate  shipping  clear  specimens
               through  customs at U.S.  entry  port,  transfer  to  appropriate
               courier/express  delivery  service for shipment  within the U.S.,
               and notify  Contractor of all  arrangements so that specimens can
               be easily  tracked.  Close  coordination  is vital  because these
               samples  may  need  to  be  kept   frozen   with  dry  ice,   and
               freezer-to-freezer  shipping  time  must be less  than 72  hours.

                                                       Contract No. NO2-CP-71001



                    INSTRUCTIONS FOR COMPLETING FORM NIH 2706
                "FINANCIAL REPORT OF INDIVIDUAL PROJECT/CONTRACT"

GENERAL INFORMATION

PURPOSE.  Form NIH 2706 is designed to: (1) provide a management tool for use by
NIH in monitoring the  application  of financial and personnel  resources to NIH
contracts,  (2) provide contractors with financial and personnel management data
which is usable in their management  processes,  (3) promptly indicate potential
areas of contract underruns or overruns by making possible comparisons of actua1
performance and projections with prior estimates on individual  elements of cost
and  personnel  and (4)  obtain  contractor's  analyses  of cause and  effect of
significant  variations  between  actual and prior  estimated of  financial  and
personnel performance.

REPORTING REQUIREMENTS

(a) SCOPE.  The specific  cost and  personnel  elements to be reported  shall be
established by mutual agreement prior to award.  The  Government may reqiure the
contractor to provide detailed documentation to support any element(s) on one or
more financial reports.  

(b) NUMBER OF COPIES AND MAILING ADDRESS. An  original and two (2) copies of the
report(s) shall be sent to the  Contracting  Officer at the address shown on the
face page of the  contract,  no later than the 30th working day after the end of
the period reported.

REPORTING STATISTICS

A modification  which extends the period of  performance of an existing contract
will not  reqiure  reporting  on a separate  Form NIH 2706,  except  where it is
determined by the  Contracting  Officer that  separate  reporting is necessary.
Furthermore,  when  incrementally  funded contracts are involved,  each separate
allotment is not considered a separate  contract entity (only a funding action).
Therefore,  the  statistics  under  incrementally  funded  contracts  should  be
reported  cumulatively  from the inception of the contract  through  completion.

DEFINITIONS  AND  INSTRUCTIONS  FOR COMPLETING FORM NIH 2706. For the purpose of
establishing  expenditure  categories in Column A, the following definitions and
instructions  will be utilized.  Each contract will specify the categories to be
reported.

(1)  PERSONNEL-PROFESSIONAL.  Included  are  the  senior  level  and  all  other
personnel whose total annual salary rates are $50,000 or more. It should include
key personnel  regardless of annnn1 salary rates. All such individuals should be
listed by names and job titles on a separate line  including  those whose salary
is not directly charged to the contract but whose effort is directly  associated
with the contract. The listing must be kept up to date.

(2)  PERSONNEL--OTHER.  This  will be  listed  as one  amount  unless  otherwise
required by the contract.

(3) FRINGE BENEFITS.  Include allowances and services provided by the Contractor
to employees as  compensation  in addition to regular  salaries and wages.  If a
fringe benefit rate(s) has been established, identify the base, rate, and amount
billed for each category. If a rate has not been established, the various fringe
benefit costs may be required to be shown separately.  Fringe benefits which are
included in the indirect cost rate should not be shown here. 

(4)  ACCOUNTABLE  PERSONAL  PROPERTY.  Nonexpendable  personal  property with an
acquisition  cost of $1,000 or more and with an  expected  useful life of two or
more years,  and sensitive items  regardless of cost.  Form HHS 565,  "Report of
Accountable  Property,  must  accompany  the   contractor's  public  voucher (SF
1034/SF  1035) or this report if not  previously  submitted.  See  "Contractor's
Guide for Control of Government Property."

COLUMN  F-CUMULATIVE  INCURRED  COST TO DATE.  The  Contractor  should enter the
combined tota1 of Columns D and E.

COLUMN  G-ESTIMATED  COST TO  COMPLETE.  Entries  need  only  be made  when  the
Contractor  estimates that a particular expenditure  category will vary from the
amount funded. Realistic estimates are essential.

COLUMN  H-ESTIMATED  COSTS AT  COMPLETION.  No entry is  required in this column
unless an entry is made in Column G.

COLUMN I-FUNDED CONTRACT AMOUNT. Enter in this column the costs agreed to during
contract negotiations for all expenditure categories listed in Column A.

COLUMN J-VARIANCE (OVER OR UNDER). This column need not be filled in when Column
H is blank. When entries have been made in Column H, this column should show the
difference between the estimated costs at completion (Column H) and funded costs
(Column 1). When a line  item varies by plus or minus 10%,  i.e., the percentage
arrived at by  dividing  Column J by Column I, an  explanation  of the  variance
should be  submitted.  In the case of an overrun (net negative  variance),  this
submission  shall not be deemed as notice under the  Limitation  of Cost (Funds)
clause of the contract.

MODIFICATIONS.  Any  modification  in the  amount  funded  for an item since the
preceding report should be listed in the appropriate cost category.

EXPENDITURES  NOT  FUNDED.  An  expenditure  for an item for which no amount was
funded  (e.g.,  at  the  discretion  of the  Contractor  in  performance  of its
contract)  should be listed in the  appropriate  cost  category  and all columns
filled in except for I. Column J will of course show a 100% variance and will be
explained along with those identified under J above.

POLICIES  AND  PRACTICES  FOR STORING,  RETRIEVING,  ACCESSING,  RETAINING,  AND
DISPOSING OF RECORDS IN THE SYSTEM:

STORAGE:
   File folders,  microfilm,  charts,  graphs,  computer tapes,  disks and punch
cards.

RETRIEVABILITY:
   By name and/or code number.

SAFEGUARDS:
   HHS contractors and collaborating researchers are required to comply with the
provisions  of  the  Privacy  Act  and  with  Department  Regulations.  Subjects
participating  in a clinical  study are advised that their identity will only be
known to those who are involved in  conducting  the study and that any published
findings will be in a format which precludes individual identification.
   1.  Authorized  Users:  Employees  who  maintain  records in this  system are
instructed to grant regular  access only to  physicians,  scientists and support
staff  of the  National  Cancer  Institute,  collaborating  researchers,  or HHS
contractors,  whose duties require the use of such  information.  Other one-time
and  special  access by other  employees  is  granted on a need to know basis as
specifically authorized by the system manager.
   2. Physical Safeguards: Data are kept in secured areas with access limited to
authorized  personnel  (system manager,  project officer,  contracting  officer,
collaborating  researchers,  staff and HHS contractors). Data transmitted to the
NCI are in form which precludes individual identification.
   3.  Proceedural  Safeguards:  For  computerized  records,  the  contractor is
required to comply, where appropriate, with Departmental standards, and National
Bureau of Standards Guidelines.  For example, access is controlled by the use of
security codes known only to authorized personnel.
   These  practices are in compliance with the standards of Chapter 45-13 of the
HHS General Administration Manual, "Safeguarding Records Contained in Systems of
Records,"  supplementary  Chapter  PHS  hf:  45-13,  and  Part 6,  "ADP  Systems
Securites," of the HHS Information  Resources Management Manual and the National
Institute of Standards and Technology Federal Information  Processing  Standards
(FIPS Pub. 41 and FIPS Pub. 31).

RETENTION AND DISPOSAL
   Records are retained  and disposed of under the  authority of the NIH Records
Control Schedule contained in NIH Manual Chapter 1743,  Appendix 1- "Keeping and
Destroying  Records" (HHS Records Management Manual,  Appendix B-361), item 3000
G-3,  which allows  records to be kept as long as they are useful in  scientific
research. Refer to the NIH Manual Chapter for specific disposition instructions.
