                                      ---------
      other than the  viral antigens listed  on  Exhibit A,  without  the  prior

      dose configurations or using [  ***   ] technologies.

      It is  furthermore recognized by the parties hereto that the parties  will
      make  good  faith  efforts  to  hereafter  negotiate  fair  and  equitable
      agreements as between them for the sale of bulk antigens to other  vaccine
      companies which  sales  should  be  included  in  the  Qualified   Revenue

      has  satisfied  the  registration  and marketing requirements set forth in
      Section 1.02 of the Original Agreement for establishing exclusivity rights

      receives an opportunity to  sell Products in  any  foreign jurisdiction(s)
      where  Distributor does  not have Product registration, then Diamond shall
      notify Distributor of its intent  to  pursue  said  opportunity in writing
      (the "Foreign Notice").  Upon Distributor's receipt of the Foreign Notice,
            --------------
      Distributor shall  have thirty (30) days  to respond in writing to Diamond

           the  extent  Diamond  has  the  Products  reasonably   available  for
           Distributor's   delivery   directions   that   conform  to  Section 4
           hereof.  Distributor  may  purchase any  additional  requirement from
           any  source,  but  only during such period that  Diamond is unable to
           meet  such  requirements  and  the  reasonable costs thereof shall be
           included   in   Minimum   Qualified   Revenues  and  to   the  extent
           contemplated  by Section 13.08,  Minimum Initial Product Revenue, for

      provided,  however,  that Distributor may permit the Qualified Revenues to

      be  less  than  the  Minimum Qualified Revenue in any Contract Year and in
      lieu thereof  pay to Diamond an amount ("Additional Payment") equal to (x)

      Qualified   Revenues  for  such   Contract  Year, multiplied  by  (y)  the
      Contract  Year Factor.   If an Additional Payment is due hereunder for any
      Contract  Year, and not paid by Distributor within (30) days after the end
      of such Contract Year, Distributor's exclusivity rights under Section 1.02
      of  this  Agreement  shall  automatically  terminate with respect  to  all
      Products;  provided,  however,   that  nothing  in  this  Agreement  shall
                 --------   -------
      impair  or  terminate Distributor's exclusivity rights with respect to any
      antigens   supplied   to  Diamond  by Distributor or through Distributor's
      agreements  with  third  party  suppliers  of  antigens  and  included  in
      Products.  Distributor's  distribution  rights  shall  then  continue on a
      non-exclusive  basis  consistent  with  the terms of this Section, subject
      to  all  the remaining terms of this Agreement not inconsistent therewith,
      which shall remain in full force and effect.

      Minimum Qualified  Revenue  shall be equal to the following amounts during
      any  Sterile   Filled   Facility  Period   for   purposes  of  determining

      Notwithstanding the foregoing, however, Distributor may permit the Initial
      Product  Qualified  Revenues to be less than the  Minimum  Initial Product

      ("Additional Initial Product Payment") equal to (x) the difference between

      such Minimum  Initial  Product  Revenue and  the  actual  Initial  Product
      Qualified Revenues for such Contract Year, multiplied by (y) the  Contract
      Year Factor. If an Additional Initial Product Payment is due hereunder for
      any Contract  Year, and not paid by Distributor within  thirty  (30)  days
      after  the  end  of  such  Contract Year, Distributor's exclusivity rights
      under  Section  1.02  of this Agreement shall automatically terminate with
      respect  to all Initial Products (but not other   Products,   subject   to
      Section 1.04(ii)(A)  of  this  Agreement).    Distributor's   distribution
      rights  shall  then  continue  with  respect  to all Initial Products on a
      non-exclusive  basis  consistent  with Section 1.04(ii)(A) subject to  all
      the  remaining  terms  of this Agreement not inconsistent therewith, which

                -----------------
      Products and counted for purposes of Section 1.04(ii)(B) of this Agreement
      shall also  count  for  purposes of determining Minimum Qualified Revenues
      under Section 1.04(ii)(A)  of  this  Agreement.   Any  Additional  Initial
      Product Payment  paid for  any  Contract  Year  shall  be credited against
      Distributor's  obligation   to  pay  an  Additional  Payment  pursuant  to
      Section 1.04(ii)(A) of  this Agreement for such Contract Year (but not for
      any other Contract Year). An example of these calculations is set forth in
      Exhibit E to this Agreement.

1.05  Responsibilities  of  Distributor; Diamond Technical Support.  Distributor
      ------------------------------------------------------------
      shall use  reasonable efforts to market and sell Products in the Territory
      and   shall  adhere  to   reasonable  industry  practice   in   connection
      therewith.  Distributor  shall  be  responsible,  at its sole expense, for
      advertising  and  promotion, technical support  and  customer service.  At
      Distributor's  request, Diamond shall provide reasonable technical support
      for Distributor's marketing, sales and customer service efforts, and shall
      pay the support costs thereof.

1.06  Registration and Licensing.   Diamond  shall  use  reasonable  efforts  to
      --------------------------
      obtain Licenses in the United States with respect to all Products and will
      pay  all Registration Costs associated with obtaining and maintaining such
      Licenses,  except  as  set  forth  in   Section 2.02.   Diamond  will  use
      reasonable  efforts  to assist Distributor in the registration of Products
      (bulk  or packed form) outside the United States at Distributor's expense.
      Distributor  shall  pay  all  Registration Costs associated with obtaining
      and  maintaining any Licenses required in the Territory outside the United
      States  and  said  cost  shall  be  included  in  the  Qualified   Revenue
      requirements  as  set  forth  in  Section 1.04(ii)(A)  and,  to the extent
      contemplated  by  Section 13.08, the  requirements of Section 1.04(ii)(B).

1.07  Specifications.  Diamond and Distributor agree that all Products  will  be
      --------------
      manufactured  in  accordance  with  the Specifications and applicable USDA
      regulations.  The  Specifications  may  be  changed  at any time by mutual

      (ii)  the  execution  and  delivery  of this Agreement by Diamond, and the
            performance of its obligations hereunder, do not require the consent
            of any third party and will not violate, with or without notice, the
            lapse of time or both, any agreement, contract, license or permit to
            which Diamond is a party or its organizational documents; and

      (iii) prior  to  delivery  of any Product hereunder it will have, and will
            thereafter   maintain,   all  required  manufacturing  establishment

            obligations with respect to such Product under this Agreement.

7.02  Of Distributor.  Distributor represents and warrants to Diamond that:
      --------------
      (i)   the execution and delivery of this Agreement by Distributor, and the
            performance of its obligations hereunder, do not require the consent
            of any third party and will not violate, with or without notice, the
            lapse of time or both, any agreement, contract, license or permit to
            which Distributor is a party or its organizational documents; and

7.03  Non-Conforming Products.  The Distributor shall have 30 days after receipt
      -----------------------

      the same.  If  the  Product  is  rejected, written notice must be given to
      Diamond  no  later  than  30 days  after  receipt by the Distributor.  The
      parties  within  30  days  after  rejection  will  endeavor  in good faith
      negotiations to determine whether or not the Product conforms to Diamond's
      warranties.   If the parties conclude it does  conform, it will be treated
      as conforming in all respects under  this Agreement with time requirements
      to  be  adjusted  to  cover  the  time required by this  process.   If the

      shipment  and in such case Diamond shall credit  against  future purchases
      by  Distributor  the purchase price of such non-conforming Product paid by
      Distributor  together  with any shipping costs paid by the Distributor for
      delivery of such non-conforming Product, or (ii) Diamond shall replace the
      non-conforming  Product  with  substitute Product which conforms with said

      hereof  based  on  the  substitute shipment, net of the purchase price and
      shipping  costs,  if  any, previously  paid  by  Distributor for such non-
      conforming  Products.    The  non-conforming  Product  shall   become  the
      property  of  and  be  returned  to Diamond at Diamond's expense.  Diamond
      shall  dispose  of  such  Product  at  its  own  expense  according to all
      appropriate  regulations.   The  Purchase  Price of non-conforming product
      shall  be  treated  as  Minimum Qualified Revenue in the Contract Year the
      product is ordered for shipment.

7.04  Recall.   Diamond shall  replace  Product at no cost to the Distributor to
      ------

      compliance  with Specifications through the dating period of such Product,

      Distributor  shall  be  responsible  for  all  other  recalls  related  to
      marketing,  handling  or storage  of Product by Distributor or its agents,
      including  voluntary  recalls  made  by  Distributor.   Minimum  Qualified
      Revenue  and, to the extent contemplated by Section 13.08, Minimum Initial
      Product  Revenue,  for  any Contract Year shall include the Purchase Price
      for product recalled under the first sentence of this Section 7.04.

- -    [   ***   ] in Qualified Revenue exceeds [   ***   ] Minimum Qualified
     Revenue requirement under 1.04(ii)(A):  No Additional Payment required to
     maintain exclusivity on Products other than Initial Products for 2004 CY.

- -    [   ***   ] in Initial Product Qualified Revenue (A + C above) does not
     meet [   ***   ] Minimum Initial Product Revenue requirement under

- -    If Distributor makes timely [   ***   ] Additional Initial Product
     Payment([   ***   ] per Section 13.07), exclusivity is maintained for
     all Products; if not, Initial Products become non-exclusive and other
     Products remain exclusive.

EXAMPLE 2
- ---------

- -    Same facts as Example 1, except as follows:

- -    Sales of Products other than Initial Products (B in Example 1) is
     [   ***  ], instead of [   ***   ]

- -    [   ***   ] in Qualified Revenue does not meet [   ***   ] Minimum

- -    If Distributor makes [   ***   ] Additional Initial Product Payment
     under 1.04(ii)(B) ([   ***   ] per Section 13.07), such payment will
     also count as an Additional Payment under 1.04(ii)(A), and exclusivity
     is maintained for all Products; if not, all Products become

     FOR  VALUE RECEIVED, the undersigned DIAMOND ANIMAL HEALTH, INC.,  an  Iowa
corporation  ("MAKER"), promises to pay to AGRI LABORATORIES, LTD.,  a  Delaware
               -----
corporation ("HOLDER"), or order, at such place as the Holder of this Note shall
              ------
designate  in writing, the sum of One Million Dollars ($1,000,000.00) in  lawful
money  of the United States of America.  Beginning from the date hereof interest
shall  accrue on the outstanding principal balance at the "prime rate" plus  one
quarter percent (0.25%) per annum.  Accrued interest shall be paid quarterly  on
each quarterly anniversary of the date of this Note, and shall accrue based upon
a  thirty-day month and a 360-day year.  Principal under this Note shall be paid
in three (3) annual installments on the first, second and third anniversaries of
the date of this Note as follows:

<table>

          <s>                                <c>
          April 15, 2003                     $250,000
          April 15, 2004                     $250,000
          April 15, 2005                     $500,000

</table>


All  principal and any accrued but unpaid interest shall be due and  payable  on
the third anniversary of the date of this Note.

     Notwithstanding any provision of this Note to the contrary,  all  principal
and unpaid accrued interest shall be due and payable on the ninetieth (90th) day
following  the  date  that  either (i) Holder's exclusivity  rights  under  that
certain Amended and Restated Bovine Vaccine Distribution Agreement dated  as  of
September  30,  2002,  (the  "Distribution Agreement")  are  terminated  due  to
                              ----------------------
Distributor's  nonpayment  of  any Additional  Payment  under  the  Distribution
Agreement  or (ii) in the event of a merger, sale or fifty percent (50%)  change
in  ownership of Maker; provided, however, that no such amounts shall be due and
payable under clause (i) of this paragraph prior to January 1, 2005.

      The  "prime rate" shall be the annual rate of interest announced from time
to  time by Wells Fargo Business Credit, Inc. ("WELLS FARGO") as its prime rate.
                                                -----------
The interest accruing on the principal balance of this Note shall fluctuate from
time  to time concurrently with changes in the prime rate, effective as  of  the
date  any change in the prime rate is publicly announced.  If Wells Fargo ceases
to  announce  the  prime rate, the prime rate as published in  the  Wall  Street
Journal in its "Money Rates" section or a similar financial publication shall be
used, as reasonably determined by Maker.

     Maker  shall have the right at any time or from time to time to prepay  all
or  a  portion of the principal or interest without premium or penalty, and such
prepayments shall be applied first to accrued interest and then to principal.

     If  default be made in the payment of any of the installments of principal,
interest,  or  other amounts when due under this Note, the entire principal  sum
and accrued interest and all other amounts due hereunder shall become due at the
option of Holder if not paid within ten (10) days of written notice to Maker.

     In  the  event garnishment, attachment, levy or execution is issued against
any  substantial or material portion of the property or assets of Maker, or  any
of them if more than one, or upon the happening of any event which constitutes a
default pursuant to the terms of any agreement or other instrument entered  into
or  given in connection herewith, or upon the adjudication of Maker, or  any  of
them  if  more  than  one,  a bankrupt, such event shall  be  deemed  a  default
hereunder  and Holder may declare this Note immediately due and payable  without
notice  to Maker or exercise any of its remedies hereunder or at law or  equity.
Should suit be brought to recover on this Note, or should the same be placed  in
the  hands  of an attorney for collection, Maker promises to pay all  reasonable
attorneys' fees and costs incurred in connection therewith.

     Failure  of Holder to exercise any option hereunder shall not constitute  a
waiver of the right to exercise the same in the event of any subsequent default,
or in the event of continuance of any existing default.

     Maker waives demand, diligence, presentment for payment, protest and notice
of  demand,  protest,  nonpayment and exercise of any option  hereunder.   Maker
agrees  that the granting without notice of any extension or extensions of  time
for  payment  of  any sum or sums due hereunder, or for the performance  of  any
covenant, condition or agreement hereof shall in no way release or discharge the
liability of Maker hereof.

     This Note shall be governed by the laws of the State of Iowa.

     Time  is  of the essence of this Note and each and every term and provision
hereof.

     This  Note is secured by that certain Security Agreement, dated as of  even
