      CONSOLIDATED STATEMENTS OF CASH FLOWS (UNAUDITED) (CONTINUED)       PAGE 6


Supplemental disclosure of non-cash investing and financing activities:

         On March 5, 1999,  Agri-Nutrition  Group Limited ("AGNU") consummated a
merger with Virbac,  Inc., a Delaware  corporation  and indirect  subsidiary  of
Virbac SA, a French corporation ("VBSA"),  pursuant to which (i) Virbac received
a cash infusion from VBSA of approximately  $13.7 million plus a contribution of
$2.0 million of  intercompany  debt that  was  recapitalized  to Virbac,  Inc.'s
equity,  (ii) AGNU issued  12,580,918 shares of its Common Stock to a subsidiary
of VBSA and (iii)  Virbac  was merged  with and into  AGNU,  with AGNU being the
surviving  entity and VBSA its  controlling  stockholder  (see Note 1).  Because
VBSA,  the parent of Virbac,  received 60% of the voting  equity of the Company,
Virbac is  considered  to be the  acquirer  for  financial  statement  purposes.
Therefore,  the Merger has been  accounted  for as a purchase of AGNU by Virbac.
See notes 1 and 2 for further discussion.

         In September  1999, the Company repaid debt in the amount of $51,000 by
issuing 37,051 shares of the Company's common stock.

wide variety of health, grooming, dental and parasiticidal products for pets and
other  companion  animals  under the  C.E.T.,  Allerderm,  St.  JON,  Zema,  and
Francodex brand names.

         The Company is the result of the March 5, 1999 merger of Virbac,  Inc.,
a  subsidiary  of Virbac  SA, a French  veterinary  pharmaceutical  manufacturer
("VBSA"),  and Agri-Nutrition  Group Limited ("AGNU"),  a publicly held company.
Pursuant  to  the  merger   agreement   dated  October  16,  1998  (the  "Merger
Agreement"),  the merger was completed by the following  series of transactions:
(i) VBSA  contributed  a total of $15.7  million to Virbac,  Inc.  consisting of
$13.7  million in cash and $2  million in  intercompany  debt  recapitalized  as
equity;  (ii) AGNU  issued  12,580,918  shares of AGNU stock to VBSA;  and (iii)
Virbac, Inc. merged with AGNU with AGNU being the surviving entity with VBSA its
majority  stockholder.  The name of the  surviving  entity  was then  changed to
Virbac Corporation.

         For financial statement reporting purposes,  the merger is considered a
purchase  of  AGNU by  Virbac,  Inc.  Accordingly,  the  accompanying  unaudited
consolidated  financial  statements are the historical  financial  statements of
Virbac,  Inc.,  which reflect its  acquisition  of AGNU as of March 5, 1999. See
Note 2.

         The accompanying  unaudited consolidated financial statements have been
prepared in accordance with the instructions to Form 10-Q and do not include all
information and footnotes required by generally accepted  accounting  principles
for  complete  financial  statements.  In  the  opinion  of  management,   these
statements  include  all  adjustments   (which  consist  of  normal,   recurring
adjustments)  necessary to present  fairly the  financial  position,  results of
operations and cash flows at and for periods ending September 30, 1999 and 1998.
The  accompanying  consolidated  statements of  operations  reflect the historic
operations of Virbac,  Inc. and include the operations of AGNU since the date of
the  Merger.  The  results of  operations  for the three  months and nine months
ending  September  30,  1999  and  1998 are not  necessarily  indicative  of the
operating  results  for the full year.  This  interim  report  should be read in
conjunction with the Virbac, Inc. and AGNU consolidated financial statements and
notes related thereto,  included in the Proxy Statement of Agri-Nutrition  Group
Limited for the 1999 Annual  Meeting of  Stockholders  filed with the Securities

the merger  announcement  (9,387,279 shares of AGNU at $1.25 per share, or $11.7
million) plus the direct acquisition cost incurred by Virbac,  Inc. The purchase

used to reduce debt.

        Also  pursuant  to the  Merger  Agreement  in April  1999,  the  Company
commenced a public  tender offer to purchase  1,000,000  shares of the Company's
outstanding Common Stock for $3.00 per share (the "Mandatory Tender Offer"). The
shares  issued to VBSA as part of the  merger  were  excluded  from this  tender
offer.  Following the Mandatory tender Offer, VBSA controls approximately 60% of
the outstanding Common Stock of the Company. In addition,  if, during the period
ending on the second  anniversary  of the merger,  the closing sale price of the
Company's  Common  Stock has not  reached  $3.00  per  share for 40  consecutive
trading days,  the Company will conduct  another public tender offer to purchase
up to 1,395,000 shares of the Company's  outstanding  Common Stock at a price of
$3.00 per share.  Pursuant to the Merger  Agreement,  such tender  offer will be
funded by  VBSA's  direct  purchase  from the  Company  of  1,395,000  shares of
unissued Common Stock at a price of $3.00 per share.

  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)     PAGE 12


        On September 7, 1999, the Company replaced all of the revolving lines of
credit with one credit  facility  of $10  million.  Of the total,  $7 million is
subject to a borrowing  formula  based upon  eligible  accounts  receivable  and
inventory  and serves as a revolving  line of credit.  The  availability  of the
remaining $3 million will be reduced by $150,000 per quarter.  At September  30,
1999,  approximately  $1.2 million was available under the credit facility.  The
interest rate and fees vary based upon the financial  performance of the Company
as  measured  by the  ratio of  EBITDA  to  interest  expense  paid and  current
maturities  due.  Interest  rates could vary from prime plus 25 basis  points to
prime minus 75 basis points.  At September 30, 1999, the interest rate was prime
minus 75 basis points, or 7.5%.

         At September 30, 1999, the Company was in compliance with all covenants
related to its credit facility.  The covenants  include minimum ratios of EBITDA
to interest  expense  plus  current  maturities  of  long-term  debt and minimum
tangible net worth requirements.

5.       Stock Options

         During the nine months ended  September  30, 1999,  options to purchase
240,500  shares of the  Company's  Common Stock were granted to  employees.  The
exercise  price of 50,000 of the  options  was $1.25 per share and was $1.34 per
share for the remaining  190,500  options.  The exercise  prices were determined
based  upon the fair value of the  shares on the dates of grant.  These  options
vest  ratably over three years from the dates of grant and will expire ten years
from the grant date. During the same period,  non-qualified  options to purchase
558,000 shares of the Company's Common Stock expired.

6.       Facility Closures

         In the third quarter,  the Company  announced its  definitive  plans to
consolidate its manufacturing and distribution operations. Under the plan, which
is already underway, all pet product distribution operations will be transferred
from the Company's Chicago, Illinois, and Los Angeles,  California facilities to
the  Company's  larger  Fort Worth,  Texas  facility.  Manufacturing  operations
currently  carried out at the Chicago  facility will cease by December 31, 1999,
and such operations will be transferred to other existing Company facilities. In
addition, manufacturing operations related to the majority of products presently
produced  at the Los  Angeles  facility  will be  transferred  to the Fort Worth
facility.

         The costs to close the Chicago facility and to reduce operations at the
Los Angeles  facility,  which comprise mostly  severance costs, are estimated at
$535,000.  These costs are  expected to be paid by December  31,  1999.  Because
these plans were initiated in connection with the merger,  these costs have been
recognized as part of the purchase price of AGNU. Additional  investments at the
remaining facilities to increase capacity are expected to be insignificant.

                   MANAGEMENT'S DISCUSSION AND ANALYSIS
              OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS           PAGE 13


Overview

         Virbac   Corporation  (the  "Company")   manufactures  and  distributes
companion animal health products.  The Company is a leader in dermatological and
oral hygiene products for companion animals, or pets, and provides a broad array
of health care products to its customers under the C.E.T.,  Allerderm,  St. JON,
Zema, and Francodex brand names.

         On March 5, 1999,  the Company,  formerly  named  Agri-Nutrition  Group
Limited,  merged  with  Virbac,  Inc.,  with the  Company  being  the  surviving
corporation.  Virbac SA, the parent of Virbac,  Inc., received 60% of the voting
equity of the Company; therefore,  Virbac, Inc. is considered to be the acquirer
for financial statement purposes. Accordingly, the merger has been accounted for
as a purchase of Agri-Nutrition Group Limited by Virbac, Inc.

         The Management's  Discussion and Analysis that follows contains forward
looking  information made pursuant to the safe harbor  provisions of the Private
Securities Litigation Reform Act of 1995. These  forward-looking  statements may
be  affected  by certain  risks and  uncertainties  described  in the  Company's
filings with the Securities and Exchange Commission. Projections of gross margin
improvements   anticipated  due  to  the   consolidation  of  manufacturing  and
distribution facilities and of expense reductions that should result from actual
or  planned  headcount  reductions  may not be  achieved  if  management  is not
vigilant  in  executing  its  plans  or if  assumptions  made in the  plans  are
inaccurate. Forward-looking statements regarding future sales may be affected by
new  competitive  or  technological  entries  into  the  market  or by  lack  of
acceptance of the  Company's  products by the market.  Therefore,  the Company's
actual results could differ materially from such forward-looking statements.

Results of Operations

         The actual  results of  operations  for the three and nine months ended
September  30, 1999 as presented in the  Consolidated  Statements  of Operations
(unaudited)  include  the  operations  of  Virbac,  Inc.  plus  the  results  of
Agri-Nutrition  since March 5, 1999.  The actual  results of operations  for the
three and nine months ended  September  1998 as  presented  in the  Consolidated
Statements of Operations (unaudited) include only the operations of Virbac, Inc.

         Because  Agri-Nutrition   operations  were  significantly  larger  than
Virbac, Inc.,  substantially all of the increase in each component is due to the
acquisition  of  Agri-Nutrition.  For the nine months  ended  September  1999 as
compared to September 1998, the acquisition  accounts for 89% of the increase in
revenue,  81% of the  increase  in  gross  profit  and  all of the  increase  in
operating  expenses.  The  impact  is just as  significant  when  comparing  the
three-month periods ending September 30, 1999 and 1998.

         For  comparative  purposes,  management  believes that an analysis upon
which 1998  results are  presented  on a basis that is  equivalent  to 1999 will
provide a more meaningful discussion of the results of operations.  To that end,
the actual results for the periods ending  September 30, 1998 have been adjusted
to  include  the  results  of  Agri-Nutrition  since  March  1998 in order to be
comparable  with the actual  results of 1999.  The 1998  amounts  have also been
adjusted to reflect the effects of the merger,  primarily  adjustments to reduce
interest expense reflecting the repayment of debt in conjunction with the merger
and adjustments to depreciation  and  amortization  related to certain  purchase
accounting  adjustments.  Management  believes the amounts and discussion  below
provide a more meaningful comparison of the Company's results of operations.

</TABLE>

Quarter Ended September 30, 1999 Compared to As Adjusted Quarter Ended September
30, 1998

     The $480  thousand,  or 4%  increase  in sales for the three  months  ended
September  30,1999 is primarily volume driven.  Positive factors impacting sales
were:

         Strong volumes of the Company's Preventic tick collar.

         The introduction of advanced  formula and patent protected  Spherulites
         in the Company's dermatological line, which management believes has led
         to an increase in market share in the dermatological line.

         Increased   volumes  of   bromethalin   rodenticides   under   contract
         manufacturing.

     These  positive  factors  were  partially  offset  by  lower  sales  in the
Company's  OTC channel due to a  combination  of  comptitive  pressures  and the
elimination of duplicate product lines resulting from the merger.

     The gross profit  percentage  remained stable at 38.4%. The Company expects
that the gross profit  percentage will improve  beginning in 2000 as the Company
consolidates its manufacturing and distribution  facilities.  This consolidation
is expected to be completed by the end of 1999, resulting in approximately  $1.1
million in annual savings.

     The Company's  operating expenses were approximately $416 thousand lower as
compared to 1998 as adjusted.  This  reduction is the result of actions taken in
the second  quarter 1999 to reduce  commercial and  administrative  costs and of
actions taken in 1998 by  Agri-Nutrition  to consolidate the Zema,  Mardel,  and
St. JON operations  into one unit.  The 1999 actions  include a 17% reduction in
commercial and  administrative  headcount,  resulting in expected net annualized
savings of $750,000.

                MANAGEMENT'S DISCUSSION (CONTINUED)                      PAGE 15

         In 1999,  income tax  expense  has been  offset by a  reduction  in the
valuation  allowance  established in prior years in connection with certain loss
carryforwards.  The  aggregate  amount  of  the  deferred  tax  asset  valuation
allowance at September 30, 1999 was approximately  $1.5 million.  This valuation
allowance  reflects  the  significant  losses  incurred  by  Virbac,   Inc.  and
Agri-Nutrition  over the last three years.  Management will continue to evaluate
the valuation  allowance  and may make an  adjustment  in the fourth  quarter if
operations  continue to improve.  If an adjustment to the valuation allowance is
made,  the  immediate  impact  would be to record an income tax  benefit for the
portion of Virbac, Inc.'s valuation allowance reversed and to reduce goodwill by
the amount of  Agri-Nutrition's  valuation  allowance  reversed.  Future periods
would then be charged a deferred tax expense at the statutory rate.

Nine Months Ended September 30, 1999 Compared to As Adjusted Nine Months Ended
September 30, 1998

         The results of operations for the nine-month period ended September 30,
1999 include the  operations of Virbac,  Inc. for the entire nine months and the
operations of  Agri-Nutrition  since the date of the merger,  March 5, 1999. For
purposes of this Management's Discussion and Analysis, 1999 amounts are compared
to 1998 amounts adjusted to include  Agri-Nutrition for the same period as 1999.
See "Results of Operations" on page 14.

         The $2.5  million or 8%  increase  in sales for the nine  months  ended
September 30, 1999 is primarily volume driven.  Positive factors impacting sales
were:

         Strong volumes of the Company's Preventic tick collar.

         The  introduction of advanced formula and patent protected  Spherulites
              in the Company's  dermatological  line, which management  believes
              have led to an  increase  in  market  share in the  dermatological
              line.

         Increased   volumes  of   bromethalin   rodenticides   under   contract
              manufacturing.

         These positive factors were partially offset by the following  negative
factors:

         A disruption to the dental line's  marketing  efforts  caused by the
           relocation of the line's marketing staff from California to Texas;
           this relocation is now complete and volumes are recovering.

         Increased competition in the OTC distribution channel, particularly for
           the insecticides.

         A shift in the Company's focus in the product lines sold through the
           OTC distribution  channel. As the Company integrates the Francodex
           business   of  Virbac,   Inc.   with  the  St.  JON   business  of
           Agri-Nutrition,  it is focusing on the more profitable products as
           it eliminates duplication.

     The improved  gross profit  percentage  (42% in 1999,  41% in 1998) reflect
fixed overhead  charges being absorbed by higher sales. The Company expects that
the gross  profit  percentage  will  improve  beginning  in 2000 as the  Company
consolidates its manufacturing and distribution  facilities.  This consolidation
is expected to be completed by the end of 1999, resulting in approximately  $1.1
million in annual savings.


<PAGE>



                  MANAGEMENT'S DISCUSSION (CONTINUED)                    PAGE 16

         The Company's operating expenses decreased a net $402 thousand compared
to 1998 due to actions  taken by  Agri-Nutrition  in 1998 to reduce costs and to
cost cutting measures taken in the second quarter 1999 to reduce  commercial and
administrative  expenses.  These measures  include a 17% reduction in commercial
and administrative  headcount,  resulting in estimated net annualized savings of
$750,000.  This  headcount  reduction  is  expected  to have no impact on sales,
because the  Company has gained  efficiencies  in  marketing  as a result of the
merger,  especially by  integrating  telemarketing  with its direct sales force.
Partially   offsetting   these   expense   reductions   were  $300  thousand  of
non-recurring expenses, such as severance pay.

         In 1999,  income tax  expense  has been  offset by a  reduction  in the
valuation  allowance  established in prior years in connection with certain loss
carryforwards.  The  aggregate  amount  of  the  deferred  tax  asset  valuation
allowance at September 30, 1999 was approximately  $1.5 million.  This valuation
allowance  reflects  the  significant  losses  incurred  by  Virbac,   Inc.  and
Agri-Nutrition  over the last three years.  Management will continue to evaluate
the valuation  allowance  and may make an  adjustment  in the fourth  quarter if
operations  continue to improve.  If an adjustment to the valuation allowance is
made,  the  immediate  impact  would be to record an income tax  benefit for the
portion of Virbac, Inc.'s valuation allowance reversed and to reduce goodwill by
the amount of  Agri-Nutrition's  valuation  allowance  reversed.  Future periods
would then be charged a deferred tax expense at the statutory rate.

Liquidity and Capital Resources

        During the nine months ended  September  30, 1999,  $2.1 million of cash
was used in operations. Although $2.5 million was generated by the Company's net
income before depreciation and amortization, working capital needs consumed $4.6
million.  The  increase  in  working  capital  reflects  increases  in  accounts
receivable and in inventory.  The increased  accounts  receivable balance arises
from the increase in sales and from seasonality. Inventory increased for several
reasons:  (1) the build-up in inventory prior to commencing the consolidation of
the  manufacturing  and distribution  facilities so that service to customers is
not interrupted; (2) the significant back-order position at the beginning of the
year;  (3) the build-up of inventory  by PMR to serve the Purina  Mills'  dealer
distribution network; and (4) the seasonality of the Company's business.

         Cash flows used in investing  activities  include cash costs related to
the merger and capital  improvements  at the  Company's St. Louis and Fort Worth
facilities.

        Cash flows from financing  activities  reflect primarily the merger with
Agri-Nutrition  Group  Limited.  In  conjunction  with the  merger,  Virbac S.A.
invested  approximately  $15.7 million in the Company.  These funds were used to
pay down debt and to repurchase  1,000,000  shares of the Company's  outstanding
Common Stock at $3.00 per share in April 1999 pursuant to the  mandatory  tender
offer required under the merger agreement. In addition, borrowing under a credit
facility increased to fund working capital needs.

        On September  7, 1999,  the Company  replaced  all of its  then-existing
credit  facilities with a three-year,  $10 million  facility,  which  management
believes is sufficient for its needs.  Of the total,  $7 million is subject to a
borrowing  formula based upon  eligible  accounts  receivable  and inventory and
serves as a revolving  line of credit.  The  availability  of the  remaining  $3
million  will be reduced by $150,000 per quarter.  At September  30, 1999,  $1.2
million was available under the credit facility. The interest rate and fees vary
based upon the financial  performance of the Company as measured by the ratio of
EBITDA to interest expense paid and current  maturities due.  Interest rates can
vary  from  prime  plus 25 basis  points  to prime  minus  75 basis  points.  At
September 30, 1999, the Company is paying prime minus 75 basis points (7.5%).

           MANAGEMENT'S DISCUSSION (CONTINUED)                           PAGE 17

         Management  believes that the Company will have sufficient cash to meet
the needs of its current  operations  for at least the next  twelve  months from
cash flows from current operations and from existing financing facilities.

        The Company has no current plans to significantly  increase  capacity of
any of its plant facilities or to expend significant  capital in modifying them.
Management is currently  consolidating  certain  manufacturing  and distribution
operations  currently  carried out at several  different  facilities and expects
such consolidation to require  expenditures of approximately  $600,000 for plant
closing costs and minor upgrades to remaining facilities. These requirements are
expected to be funded  from  current  operations  and from the  existing  credit
facility.

        The Company is committed to conduct a public tender offer to purchase up
to 1,395,000 of the Company's  outstanding  Common Stock at a price of $3.00 per
share if, during the period ending on the second  anniversary of the merger, the
closing sale price of the Company's Common Stock has not reached $3.00 per share
for a period of 40 consecutive  trading days.  Pursuant to the merger agreement,
such tender offer,  if necessary,  will be funded by Virbac SA's direct purchase
from the Company of 1,395,000 shares of Common Stock at $3.00 per share.

         The  Company  has no  plans to pay  dividends  to  stockholders  in the
foreseeable future.

Year 2000 Compliance

         The Year  2000  issue  arises as a result of  computer  programs  being
written  using  two  digits  rather  than four to define  the  applicable  year.
Consequently,  these computer programs may contain time-sensitive software which
recognizes  a date using "00" as the year 1900  rather  than the year 2000.  The
impact of the Year 2000 issue extends beyond  traditional  computer hardware and
software  systems  and  may  potentially  impact  telephone  systems,   building
facilities systems, security systems and systems utilized by outside vendors and
customers.  Failure to effectively address the Year 2000 issue could result in a
disruption of operations and the inability to process transactions or to perform
other normal business activities.

         The Company has reviewed  its key  hardware  and  software  systems for
compliance.  Those  systems that were not in  compliance  have been  repaired or
updated to support  Year 2000  compliance.  The repairs and  upgrades  have been
tested or are in the process of being  tested.  Less critical  systems,  such as
personal  computers,  have also been  evaluated  and  upgraded.  The cost of the
repairs and upgrades to the key  hardware  and software  systems and to the less
critical  systems  have not been,  and are not  expected to be,  material to the
Company's financial statements.

         The  Company is  completing  the  evaluation  of its  mission  critical
vendors and  suppliers.  The Company  recognizes  that if its external  business
partners  experience any  significant  Year 2000 problems,  they could adversely
effect its business operations.  The most likely worst case scenario,  which the
Company does not believe will occur, is that business is interrupted  because of
Year 2000  problems at one or more of its business  partners  such as vendors or
customers.  The Company is unable to estimate the impact on its income statement
if such an event were to occur. Accordingly, the Company continues to assess its
risks and take appropriate actions to mitigate identified risks.

         The  Company   believes  that  the  Year  2000  issues  will  not  pose
significant operational problems for the Company because of its preparedness and
because the Company's operations are not driven by systems technology.  However,
there can be no  assurance  that the Company will not  experience  unanticipated
costs and/or  business  interruptions  due to Year 2000 problems in its internal
systems,  its supply chain or from customer product  migration  issues,  or that
such costs and/or  interruptions  will not have a material adverse effect on the
Company's consolidated results of operations.

SECTION 3.  THE LOANS.

                  3.1      Commitment of Bank.

                  (a)  Facility A. Subject to the terms and  conditions  hereof,
during  the Term of this  Agreement,  Bank  hereby  agrees  to make  such  loans
(individually,  a "Facility A Loan" and collectively, the "Facility A Loans") to
Borrowers,  jointly and severally, as any of the Borrowers may from time to time
request  pursuant to Section 3.2 and in Bank's  discretion,  to issue Letters of
Credit for the account of the  Borrowers,  or any of them,  upon any  Borrower's
execution  of a Letter of Credit  Application  therefor  pursuant to Section 3.3
(subject to Bank's approval of the form of the Letters of Credit requested to be
issued). The maximum aggregate principal amount of Loans plus the face amount of
issued  and  outstanding  Letters of Credit  which  Bank,  cumulatively,  may be
required  to have  outstanding  under this  Facility A at any one time shall not
exceed  the  lesser  of  Seven  Million  Dollars  ($7,000,000.00),  or (ii)  the
Borrowing  Base (as  hereinafter  defined).  This  commitment  of Bank is herein
sometimes  referred to as the  "Bank's  Facility A  Commitment."  Subject to the
terms and conditions hereof,  Borrowers may jointly and severally borrow,  repay
and  reborrow  such  sums  from  Bank,  provided,  however,  that the  aggregate
principal  amount of all Facility A Loans  outstanding  hereunder  plus the face
amount of Letters of Credit  issued and  outstanding  hereunder  at any one time
shall not exceed Bank's Facility A Commitment.

                  (b)  Facility B. Subject to the terms and  conditions  hereof,
during  the Term of this  Agreement,  Bank  hereby  agrees  to make  such  loans
(individually,  a "Facility B Loan" and collectively, the "Facility B Loans") to
Borrowers,  jointly and severally, as any of the Borrowers may from time to time
request  pursuant to Section 3.2. The aggregate  principal  amount of Facility B
Loans which Bank, cumulatively,  shall be required to have outstanding hereunder
at any one time shall not exceed Three Million Dollars  ($3,000,000.00) from the
date hereof until November 29, 1999, which amount shall thereafter be reduced by
One Hundred Fifty Thousand  Dollars  ($150,000.00)  on each February 28, May 31,
August 31 and November 30,  commencing with the first such reduction on November
30, 1999. This commitment of Bank is herein sometimes referred to as the "Bank's
Facility B Commitment."  Subject to the terms and conditions  hereof,  Borrowers
may  jointly  and  severally  borrow,  repay and  reborrow  such sums from Bank,
provided,  however,  that the aggregate principal amount of all Facility B Loans
outstanding  under Bank's Facility B Commitment at any one time shall not exceed
Bank's Facility B Commitment then available hereunder.  Bank and Borrowers agree
that all Loans (but not including  Letters of Credit which in all cases shall be
issued under  Facility A) outstanding  under this Agreement  shall first be made
under Facility B up to the Bank's Facility B Commitment,  and then shall be made
under  Facility A, and all  principal  payments  shall be applied,  first to the
outstanding  principal  under  Facility  A until  paid in full,  and then to the
outstanding principal under Facility B. The Facility B Loans may be either (a) a
Prime Loan, (b) a LIBOR Loan or (c) any  combination  thereof,  as determined by
the Borrowers  and notified to the Bank in  accordance  with Section 3.2 herein,
provided,  however,  that the amount of any Loan under this Section 3.1(b) which
is a  LIBOR  Loan  shall  be for  an  aggregate  principal  amount  of at  least
$500,000.00 or any larger multiple of $100,000.00.

                  (c)  Borrowing  Base.  For purposes of computing the amount of
the Bank's Facility A Commitment, the "Borrowing Base" shall mean the sum of:

                  (i) Seventy-Five  Percent (75%) of the face amount of Eligible
Accounts of each of the Borrowers, plus

                           (ii) Forty Percent (40%) of the Eligible Inventory of
each of the Borrowers.

                  (d) Borrowing  Base  Certificate.  Borrowers  shall deliver to
Bank on the date of execution  hereof (with  respect to the month ended July 31,
1999) and on the twenty-eighth  (28th) day of each month thereafter,  commencing
in the month of September,  1999, a borrowing  base  certificate  in the form of
Exhibit A attached  hereto and  incorporated  herein by reference (a  "Borrowing
Base Certificate") setting forth:

                  (i) the Borrowing Base and its components as of the end of the
immediately preceding month;

                           (ii)   the   aggregate   principal   amount   of  all
         outstanding  Facility  A Loans  and the  aggregate  face  amount of all
         issued and outstanding Letters of Credit;

                           (iii) the difference,  if any,  between the Borrowing
         Base and the aggregate  principal amount of all outstanding  Facility A
         Loans plus the  aggregate  face  amount of all  issued and  outstanding
         Letters of Credit; and

                           (iv) the maximum  available  principal amount and the
         aggregate principal amount of all outstanding Facility B Loans.

The Borrowing Base shown in such Borrowing Base Certificate  shall be and remain
the Borrowing  Base  hereunder  until the next  Borrowing  Base  Certificate  is
delivered to Bank, at which time the Borrowing Base shall be the amount shown in
such  subsequent  Borrowing Base  Certificate.  Each Borrowing Base  Certificate
shall be  certified  (subject to normal  year-end  adjustments)  as to truth and
accuracy by the President,  principal financial officer or controller of each of
the Borrowers.

                  (e)  Mandatory  Repayments  -  Facility  A. If at any time the
Borrowing Base as shown on the most recent Borrowing Base Certificate  should be
less than the aggregate  principal  amount of all  outstanding  Facility A Loans
plus the aggregate face amount of all issued and outstanding  Letters of Credit,
Borrowers shall be automatically  required (without demand or notice of any kind
by Bank,  all of which are hereby  expressly  waived by  Borrowers)  jointly and
severally to immediately  repay the Facility A Loans in an amount  sufficient to
reduce such aggregate principal amount of outstanding  Facility A Loans plus the
outstanding  face  amount of Letters  of Credit to the  amount of the  Borrowing
Base.

                  (f)  Mandatory  Repayments - Facility B.  Commencing  with the
first such  principal  reduction on November 30, 1999,  on each February 28, May
31,  August 31 and  November 30  thereafter  during the Term of this  Agreement,
Borrowers shall jointly and severally pay to Bank in immediately available funds
an amount equal to the  difference  between  Bank's  Facility B  Commitment  (as
reduced  on such date  pursuant  to the terms of Section  3.1(b)  above) and the
aggregate  principal  amount of all  Facility B Loans then  outstanding.  In the
event any such mandatory repayment shall be due on a day which is not a Business
Day, then such payment shall be due on the immediately  preceding  Business Day.
Such  mandatory  payments shall be applied first to the  outstanding  Facility B
Loans  which are Prime  Loans,  and second to  Facility B Loans  which are LIBOR
Loans,  provided,  however,  that any such  repayment of LIBOR Loans made on any
date other than the last day of the  applicable  Interest  Period for such LIBOR
Loan shall be subject to payment  jointly  and  severally  by  Borrowers  of the
amounts due under Section 3.8 below.

                  3.2  Procedure  for  Borrowing.   Subject  to  the  terms  and
conditions hereof, Bank shall cause the Loans to be made to Borrowers, and shall
convert outstanding Prime Loans under Facility B to LIBOR Loans or vice versa or
shall  continue  any  outstanding  LIBOR Loan as a LIBOR Loan for a new Interest
Period, at any time and from time to time during the Term of this Agreement upon
timely  prior  oral or  written  notice  ("Borrowing  Notice")  from  any of the
Borrowers to Bank specifying:

                           (i) the  desired  amount  of the  Facility  A Loan or
         Facility  B Loan  requested  which  in the case of a LIBOR  Loan  under
         Facility  B shall be in a  principal  amount of at least  Five  Hundred
         Thousand Dollars ($500,000.00);

                           (ii)  whether  such  Loan  shall be a new Loan  under
         Facility A or  Facility B, or a  conversion  of all or a portion of any
         presently  outstanding Facility B Loan from the Prime Rate to the LIBOR
         Rate, or vice versa,  or a continuation of an expiring LIBOR Loan for a
         new Interest Period;

                           (iii)    if a new Loan under Facility B, whether such
         Loan is to be a Prime Loan or a LIBOR Loan;

                           (iv) in the case of a LIBOR Loan, the duration of the
         Interest Period  applicable  thereto,  subject to the provisions of the
         definition of Interest Period;

                           (v) the date on which  the  proceeds  of any new Loan
         are to be made  available to any of the  Borrowers or the date on which
         the new interest rate is to take effect for any outstanding  Facility B
         Loan being  converted  or  continued  by  Borrowers,  which  shall be a
         Business Day;

                           (vi) that on the date of, and after giving effect to,
         such Loan,  no Default or Event of  Default  under this  Agreement  has
         occurred and is continuing; and

                           (vii)  that on the date of, and after  giving  effect
         to, such Loan, all of the  representations  and warranties of Borrowers
         contained  in this  Agreement  are true  and  correct  in all  material
         respects as if made on the date of such Loan.

A Borrowing Notice shall not be required in connection with a Prime Loan made to
cover any overdraft in Virbac's  operating  account on a day-to-day basis as set
forth herein.  A Borrowing  Notice,  if in writing,  shall be in the form of the
notice attached as Exhibit B hereto.  Each Borrowing  Notice must be received by
Bank not later than 10:00 a.m.  (St.  Louis time) on the Business Day on which a
Prime Loan is to be established,  and not later than 10:00 a.m. (St. Louis time)
on the second Eurodollar Business Day prior to the date on which a LIBOR Loan is
to be  established or continued,  as the case may be;  provided,  however,  that
notwithstanding  the foregoing,  in addition to and without  limiting the rights
and remedies of the Bank under Section 8 hereof, so long as any Default or Event
of Default under this Agreement has occurred and is continuing,  Borrowers shall
not be permitted to renew any LIBOR Loan as a LIBOR Loan or to convert any Prime
Loan into a LIBOR Loan. If the Bank does not receive a Borrowing  Notice for the
continuation  of an existing  LIBOR Loan for a new  subsequent  Interest  Period
pursuant to the preceding  sentence within the applicable time limits  specified
therein, Borrowers shall be deemed to have elected to convert such LIBOR Loan on
the last day of the current Interest Period with respect thereto to a Prime Loan
in the  principal  amount of such  expiring  LIBOR Loan on such date.  All Loans
which bear interest at a particular LIBOR Rate for a particular  Interest Period
shall  constitute a single LIBOR Loan.  Borrowers may not have  outstanding  and
Banks shall not be  obligated to make more than three (3) LIBOR Loans at any one
time. A Borrowing  Notice shall not be  revocable by  Borrowers.  Subject to the
terms and  conditions  hereof,  provided  that Bank has received  the  Borrowing
Notice,  Bank  shall  (unless  Bank  determines  that any  applicable  condition
specified in Section 4 has not been satisfied) pay to Borrowers, or any of them,
the Loan proceeds of any new Loan in immediately  available funds not later than
2:00 p.m.  (St.  Louis time) on the  Business Day  specified  in said  Borrowing
Notice.  Each of the Borrowers  hereby  authorizes  Bank to  reasonably  rely on
telephonic,  telegraphic,  telecopy, telex or written instructions of any person
identifying himself as a person authorized to request a Loan or make a repayment
hereunder, and on any signature which Bank believes to be genuine, and Borrowers
shall be bound  thereby  in the same  manner  as if such  person  were  actually
authorized  or such  signature  were  genuine.  Borrowers  further  request  and
authorize Bank, in Bank's sole and absolute discretion,  to make a Prime Loan to
Borrowers  hereunder  at the end of each day in which  Borrowers  shall  have an
overdraft  (negative ledger balance) in Virbac's  operating account (Account No.
9800801785)  with Bank after  crediting  all  deposits  received in  immediately
available funds and debiting all withdrawals made and checks  presented  against
such account and honored by Bank as of such date and after  funding any advances
to or  receiving  any  collected  balances  on such day from the "zero  balance"
operating  accounts of PM Resources (Account No.  9800802535),  St. JON (Account
No.  9800805419),  Virbac AH (Account No. 9821908926) and Francodex (Account No.
____________)  with Bank to cover  withdrawals made and checks presented on such
date and after crediting all deposits received in immediately available funds on
such date, which Prime Loan shall be in the amount of such overdraft without any
other request or  authorization  therefor from  Borrowers and without  notice to
Borrowers.  Similarly,  Borrowers request that Bank apply any collected balances
(after  funding  advances to or receiving  collections  from the "zero  balance"
accounts of PM  Resources,  St.  JON,  Virbac AH and  Francodex)  in excess of a
mutually  predetermined  amount  remaining  at the  end of any  day in  Virbac's
operating  account to the  repayment  of the  principal  balance  of  Borrowers'
Obligations  outstanding  as Prime Loans under the Note.  Borrowers  also hereby
agree  jointly and  severally to indemnify  Bank and hold Bank harmless from and
against any and all claims,  demands,  damages,  liabilities,  losses, costs and
expenses (including, without limitation, Attorneys' Fees) relating to or arising
out of or in connection with the acceptance of instructions  for making Loans or
repayments  hereunder.  Contemporaneously  with the execution of this Agreement,
Borrowers  shall execute and deliver to Bank a Note of Borrowers dated as of the
date  hereof  and  payable  jointly  and  severally  to the order of Bank in the
original  principal amount of Ten Million Dollars  ($10,000,000.00)  in the form
attached hereto as Exhibit C and  incorporated  herein by reference (as the same
may from time to time be amended, modified, extended or renewed, the "Note").

                  3.3      Letters of Credit.

                  (a)  Subject to the terms and  conditions  of this  Agreement,
during the Term of this Agreement, and so long as no Default or Event of Default
under this Agreement has occurred and is continuing, Bank hereby agrees to issue
irrevocable  standby  letters of credit or commercial  letters of credit for the
account of any of the  Borrowers,  or to cause other banks to issue  irrevocable
standby letters of credit or commercial letters of credit for the account of any
of the  Borrowers by  indemnifying  such other banks for  Borrowers  obligations
thereunder  (each  individually,  a "Letter of  Credit"  and  collectively,  the
"Letters of Credit") in an amount and for the term specifically requested by any
of the Borrowers by  application  in writing to Bank (or such other bank) in the
form of Exhibit F attached  hereto and  incorporated  herein by reference in the
case of a standby Letter of Credit,  or in the form of Exhibit G attached hereto
and  incorporated  herein by  reference  in the case of a  commercial  Letter of
Credit (each a "Letter of Credit  Application") at least three (3) Business Days
prior to the requested issuance thereof; provided, however, that:

                           (i)  Borrowers,  or any of them,  shall have executed
         and  delivered to Bank a Letter of Credit  Application  with respect to
         such Letter of Credit;

                           (ii) the term of any such Letter of Credit  shall not
         extend beyond the last day of the Term hereof;

                           (iii)  the  aggregate  undrawn  face  amount  of  all
         outstanding Letters of Credit plus the outstanding  principal amount of
         all Facility A Loans shall not at any one time exceed the lesser of (a)
         the Borrowing Base or (b) the Bank's Facility A Commitment;

                           (iv)  the  aggregate   undrawn  face  amount  of  all
         outstanding  Letters of Credit  issued  hereunder  shall not at any one
         time exceed One Million Dollars ($1,000,000.00); and

                           (v) the text of any such Letter of Credit is provided
         to Bank no less than three (3)  Business  Days  prior to the  requested
         issuance  date,  which text must be  acceptable to Bank in its sole and
         absolute discretion.

                  (b) The payment of drafts under each Letter of Credit shall be
made in accordance with the terms thereof and, in that connection,  Bank (or any
other issuing bank thereof) shall be entitled to honor any drafts and accept any
documents  presented  to it by the  beneficiary  of such  Letter  of  Credit  in
accordance  with the terms of such Letter of Credit and  reasonably  believed by
Bank (or such issuing  bank) to be genuine.  Bank (or such other  issuing  bank)
shall not have any duty to inquire as to the  accuracy  or  authenticity  of any
draft or other  drawing  document  that may be  presented  to it other  than the
duties contemplated by the applicable Letter of Credit Application.  If Bank (or
such other  issuing  bank) shall have  received  documents  that in its judgment
constitute all of the documents that are required to be presented before payment
or acceptance  of a draft under a Letter of Credit,  it shall be entitled to pay
such draft provided such documents  conform on their face to the requirements of
such Letter of Credit.

                  (c) In the event of any  payment by Bank of a draft  presented
or accepted under a Letter of Credit,  Borrowers  jointly and severally agree to
pay to Bank in immediately available funds at the time of such drawing an amount
equal to the sum of such drawing plus Bank's customary  negotiation,  processing
and other fees related  thereto.  Borrowers  hereby  authorize Bank to charge or
cause to be charged to Borrowers'  bank accounts at Bank to the extent there are
balances of immediately  available funds therein,  in an amount equal to the sum
of such drawing plus Bank's  customary  negotiation,  processing  and other fees
related thereto,  and Borrowers jointly and severally agree to pay the amount of
any such drawing (and/or Bank's customary negotiation, processing and other fees
related  thereto)  not so charged  prior to the close of business of Bank on the
day of such  drawing.  In the event any payment under a Letter of Credit is made
by Bank prior to receipt of payment from  Borrowers,  such payment by Bank shall
constitute  a request by  Borrowers  for a Facility A Loan as a Prime Loan under
Section 3.1(a) above.

                           (d)(i) Borrowers shall also pay to Bank, with respect
         to each  standby  Letter of Credit,  all wire  transfer  fees,  courier
         charges and other out of pocket expenses  incurred by Bank from time to
         time, which amounts shall be due and payable on demand by Bank; and

                           (ii) Borrowers shall pay to Bank with respect to each
         Letter of Credit for the period  during  which such Letter of Credit is
         outstanding:

                           (1) in the case of any  standby  Letter of Credit,  a
                  nonrefundable Letter of Credit commitment fee in an amount per
                  annum  equal  to  the  greater  of  (A)  One  Hundred  Dollars
                  ($100.00) or (B) the  applicable  Letter of Credit  Commitment
                  Fee Rate in  effect  for the  fiscal  quarter  in  which  such
                  standby  Letter of Credit is issued  (calculated  on an actual
                  day,  360-day year basis)  times the face amount  (taking into
                  account any scheduled  increases or decreases  therein  during
                  the  fiscal  quarter in  question)  of the  standby  Letter of
                  Credit then being issued hereunder; or

                           (2)  such  up-front  fee in the  case  of  each  such
                  commercial Letter of Credit as shall be determined by Bank and
                  agreed to by Borrowers prior to the issuance thereof ;

         ("Letter of Credit Commitment Fee"),  which Letter of Credit Commitment
         Fee shall be due and payable in advance on the date of issuance of each
         such  Letter of Credit and on each  renewal  date of any such Letter of
         Credit.

                  (e)  Notwithstanding any provision contained in this Agreement
or any of the Letter of Credit Applications to the contrary, upon the occurrence
of any Event of  Default  under this  Agreement,  at Bank's  option and  without
demand or further notice to Borrowers,  an amount equal to the aggregate undrawn
face  amount of all  Letter(s)  of Credit then  outstanding  shall be deemed (as
between   Bank  and   Borrowers)   to  have  been  paid  or  disbursed  by  Bank
(notwithstanding  that  such  amounts  may  not in  fact  have  been  so paid or
disbursed by Bank),  and which amount shall be immediately  due and payable.  In
lieu of the foregoing,  at the election of Bank upon the occurrence of any Event
of Default under this Agreement, Borrowers shall, upon Bank's demand, deliver to
Bank  cash,  or other  collateral  acceptable  to Bank in its sole and  absolute
discretion,  having a  value,  as  determined  by  Bank,  at least  equal to the
aggregate  undrawn face amount of all  outstanding  Letters of Credit.  Any such
collateral  and/or any amounts received by Bank for such Letters of Credit shall
be held by Bank in a separate account at Bank appropriately designated as a cash
collateral  account in relation to this  Agreement and the Letters of Credit and
retained  by  Bank  as  collateral   security  for  the  payment  of  Borrowers'
Obligations hereunder.  Cash amounts delivered to Bank pursuant to the foregoing
requirements  of this  Section  shall be  invested,  at the  request and for the
account of any of the Borrowers,  in investments of a type and nature and with a
term  acceptable to Bank.  Such  amounts,  including in the case of cash amounts
invested in the manner set forth above, any interest  realized  thereon,  may be
applied to  reimburse  Bank for  drawings or  payments  under or pursuant to the
Letters of Credit which Bank has paid, or if no such  reimbursement  is required
to the payment of such other of Borrowers'  Obligations as Bank shall determine.
Any amounts  remaining in any cash collateral  account  established  pursuant to
this Section after the payment in full of all of Borrowers'  Obligations and the
expiration or  cancellation of all of the Letters of Credit shall be returned to
Borrowers, or any of them (after deduction of Bank's expenses, if any).

                  3.4      Interest Rates.

                  (a) Each Facility A Loan shall bear interest prior to maturity
at a rate per annum equal to the Prime Rate plus Floating  Rate Margin,  each in
effect from time to time during the period when such Loan is  outstanding,  with
changes in the interest  rate taking effect on the date a change in the Floating
Rate Margin occurs  pursuant to the  definition  thereof or the date a change in
the Prime Rate is made effective generally by Bank.

                  (b) Each Facility B Loan shall bear interest prior to maturity
at a rate per annum equal to such of the following as any of the Borrowers shall
select in the applicable Borrowing Notice to Bank:

                           (i) the Prime Rate plus Floating Rate Margin, each in
         effect from time to time during the period when such Facility B Loan is
         outstanding,  with  changes in the interest  rate taking  effect on the
         date a change  in the  Floating  Rate  Margin  occurs  pursuant  to the
         definition  thereof  or the date a  change  in the  Prime  Rate is made
         effective generally by Bank; or

                           (ii) the LIBOR Rate applicable for an Interest Period
         selected  by any  Borrower  for such  Facility B Loan in the  Borrowing
         Notice applicable for such Facility B Loan.

                  (c) From and after the maturity of the Note, whether by reason
of acceleration or otherwise,  the entire unpaid principal  balance of each Loan
shall bear interest,  payable upon demand,  until paid at a rate per annum equal
to Three and One-Half Percent (3.50%) over and above the Prime Rate, fluctuating
as aforesaid.

                           (d)  Interest  shall be computed  with respect to all
Loans on an actual day, 360-day year.

                  3.5 Prepayment. Borrowers shall be privileged to prepay all at
any time or any portion  from time to time of the unpaid  principal of any Prime
Loan prior to maturity, without penalty or premium, provided that such repayment
is made on a Business  Day.  Borrowers  shall be  privileged  to repay,  without
penalty or premium, the principal of any LIBOR Loan, in whole or in part, on the
last day of the Interest Period applicable thereto, provided that such repayment
is made on a Business Day.  Borrowers shall not make any optional  prepayment of
the principal of any LIBOR Loan before the last day of its  applicable  Interest
Period,  and any  payments of principal of any LIBOR Loan on any date other than
the last day of the  applicable  Interest  Period shall be subject to payment of
the amounts required under Section 3.8 below.  All prepayments  shall be applied
solely to the payment of principal.

                  3.6 Interest  Payments.  Borrowers shall jointly and severally
pay Bank all interest  which  accrued on all Prime Loans during any month on the
fifteenth  (15th) day of the month  following  the month in which such  interest
accrued,  commencing  with the fifteenth  (15th) day of the month  following the
month in which any Prime Loan is made. Borrowers shall jointly and severally pay
Bank with respect to each LIBOR Loan (a) on the last day of the Interest  Period
applicable  to each such  LIBOR  Loan,  and (b) if any such  Interest  Period is
longer than three months,  then also on the date which is three months after the
commencement  of such Interest  Period,  all then accrued and unpaid interest on
such LIBOR Loan. Notwithstanding any provision contained herein to the contrary,
all accrued and unpaid  interest  shall also be paid at the  maturity of each of
the Note,  whether by reason of  acceleration  or  otherwise,  and any  interest
accruing  after any such  maturity  shall be payable  upon  demand.  In case any
installment  of interest  shall become due on a day which is not a Business Day,
interest shall be computed to, and payable on, the next succeeding Business Day,
except  that in the case of LIBOR Loans such  payment  dates shall be subject to
the definition of Interest  Period.  If the date for any payment of principal is
extended  by  operation  of law or  otherwise,  interest  thereon,  at the  then
applicable rate, shall be payable for such extended time.

                  3.7 Place and Manner of Payment.  Both  principal and interest
on the Loans are  payable to Bank in lawful  currency  of the  United  States in
Federal or other  immediately  available  funds at Bank's banking office at 1281
Graham Road,  Florissant,  Missouri  63031, or at such other place as Bank shall
designate in writing to Borrowers.

                  3.8 Funding Losses.  Notwithstanding  any provision  contained
herein to the contrary,  if any of the Borrowers  makes any payment of principal
with  respect  to any LIBOR  Loan  (pursuant  to this  Section  3,  Section 8 or
otherwise) on any day other than the last day of an Interest  Period  applicable
thereto,  or if any of the Borrowers fails to borrow or pay any LIBOR Loan after
notice has been given by Borrowers in  accordance  with Section  3.1(f),  3.2 or
3.6,  Borrowers  shall  jointly and severally  reimburse  Bank on demand for any
resulting losses and expenses incurred by Bank,  including,  without limitation,
any losses incurred in obtaining,  liquidating or employing  deposits from third
parties,  and including  loss of margin for the period after any such payment is
made. A certificate  of Bank  demanding  compensation  under this  paragraph and
setting  forth  the  amount  or  amounts  to be paid to it  hereunder  shall  be
conclusive in the absence of manifest error.

                  3.9 Basis for Determining  Interest Rate Inadequate or Unfair.
If with respect to any Interest Period:

                  (a)  Bank   determines   that  deposits  in  dollars  (in  the
applicable  amounts) are not being  offered to Bank in the  relevant  market for
such Interest Period, or

                  (b) Bank  determines that the LIBOR Rate as determined by Bank
will not  adequately  and  fairly  reflect  the cost to Bank of  maintaining  or
funding its LIBOR Loans for such Interest Period,  the Bank shall forthwith give
notice thereof to Borrowers,  whereupon  until Bank notifies  Borrowers that the
circumstances   giving  rise  to  such  suspension  no  longer  exist,  (a)  the
obligations  of the  Bank  to make  LIBOR  Loans  shall  be  suspended,  and (b)
Borrowers shall repay in full the then  outstanding  principal amount of each of
their LIBOR Loans together with all accrued and unpaid interest thereon,  on the
last  day  of  the  then  current  Interest  Period  applicable  to  such  Loan.
Concurrently  with  repaying  each  such  LIBOR  Loan of Bank  pursuant  to this
Section,  Borrowers  may borrow a Prime Loan in an equal  principal  amount from
Bank,  and,  if  Borrowers  so  elect,  Bank  shall  make  such a Prime  Loan to
Borrowers.

                  3.10  Illegality.  If, after the date of this  Agreement,  the
adoption of any applicable law, rule or regulation,  or any change  therein,  or
any change in the  interpretation or administration  thereof by any governmental
or  regulatory  authority,  central bank or comparable  agency  charged with the
interpretation or administration thereof, or compliance by Bank with any request
or directive  (whether or not having the force of law) of any such  governmental
or  regulatory  authority,  central  bank or  comparable  agency  shall  make it
unlawful  or  impossible  for Bank to make,  maintain or fund its LIBOR Loans to
Borrowers,  Bank shall forthwith give notice thereof to Borrowers.  Upon receipt
of such notice,  Borrowers  shall repay in full the then  outstanding  principal
amount of each of their  LIBOR  Loans from Bank,  together  with all accrued and
unpaid interest thereon, on either (a) the last day of the then current Interest
Period  applicable to such LIBOR Loan if Bank may lawfully  continue to maintain
and fund such LIBOR Loan to such day or (b) immediately if Bank may not lawfully
continue to fund and  maintain  such LIBOR Loan to such day.  Concurrently  with
repaying each LIBOR Loan of Bank,  Borrowers may borrow a Prime Loan in an equal
principal  amount from Bank, and, if Borrowers so elect,  Bank shall make such a
Prime Loan to Borrowers.

                  3.11     Increased Cost.

                  (a) If (i)  Regulation  D or (ii) after the date  hereof,  the
adoption of any applicable law, rule or regulation,  or any change  therein,  or
any change in the  interpretation or administration  thereof by any governmental
or  regulatory  authority,  central bank or comparable  agency  charged with the
interpretation or administration thereof, or compliance by Bank with any request
or directive  (whether or not having the force of law) of any such  governmental
or  regulatory  authority,  central  bank or  comparable  agency (a  "Regulatory
Change"):

                           (A)  shall  subject  Bank to any  tax,  duty or other
         charge with respect to its LIBOR Loans,  the Note or its  obligation to
         make LIBOR Loans  hereunder,  or shall  change the basis of taxation of
         payments to Bank of the  principal of or interest on its LIBOR Loans or
         any other  amounts  due under  this  Agreement  in respect of its LIBOR
         Loans or its  obligation  to make LIBOR  Loans  (except for taxes on or
         changes in the rate of tax on the overall net income of Bank); or

                           (B)  shall  impose,  modify  or deem  applicable  any
         reserve  (including,  without  limitation,  any reserve  imposed by the
         Board of Governors of the Federal  Reserve  System),  special  deposit,
         capital or similar  requirement against assets of, deposits with or for
         the account of, or credit extended or committed to be extended by, Bank
         or shall,  with  respect to Bank or the  Interbank  Eurodollar  market,
         impose,  modify or deem  applicable any other  condition  affecting its
         LIBOR Loans, the Note or its obligation to make LIBOR Loans;

and the result of any of the  foregoing  is to  increase  the cost to (or in the
case of  Regulation  D, to  impose  a cost on or  increase  the cost to) Bank of
making  or  maintaining  any LIBOR  Loan,  or to  reduce  the  amount of any sum
received  or  receivable  by Bank  under this  Agreement  or under its Note with
respect thereto, by an amount deemed by Bank to be material,  and if Bank is not
otherwise  fully  compensated  for such  increase in cost or reduction in amount
received or  receivable  by virtue of the  inclusion of the  reference to "LIBOR
Reserve  Percentage" in the calculation of the interest rate applicable to LIBOR
Loans,  then, upon notice by Bank to Borrowers  together with Bank's calculation
of the  increased  cost or  reduction  of any  amount  to be  received  by Bank,
Borrowers  shall promptly pay to Bank as additional  interest,  such  additional
amount or amounts as will  compensate Bank for such increased cost or reduction.
Bank will  promptly  notify  Borrower  of any  event of which it has  knowledge,
occurring  after  the date  hereof,  which  will  entitle  Bank to  compensation
pursuant to this Section.  The  determination  by Bank under this Section of the
additional  amount or amounts to be paid to it hereunder  shall be conclusive in
the absence of manifest error. In determining  such amount or amounts,  Bank may
use any reasonable averaging and attribution methods.

                  (b) If Bank demands compensation under this Section, Borrowers
may at any time,  upon at least two (2)  Business  Days'  prior  notice to Bank,
repay in full their then outstanding LIBOR Loans,  together with all accrued and
unpaid  interest  thereon to the date of prepayment  and any funding  losses and
other  amounts due under  Section 3.8.  Concurrently  with  repaying  such LIBOR
Loans,  Borrowers  may borrow  from Bank a Prime Loan in an amount  equal to the
aggregate principal amount of such LIBOR Loans, and, if Borrowers so elect, Bank
shall make such a Prime Loan to Borrowers.

                  3.12 Prime Loans  Substituted  for Affected  LIBOR  Loans.  If
notice has been given by Bank  pursuant to Section  3.9 or 3.10 or by  Borrowers
pursuant to Section 3.11(b) requiring LIBOR Loans to be repaid, then, unless and
until  Bank  notifies  Borrowers  that  the  circumstances  giving  rise to such
repayment no longer  apply,  all Loans which would  otherwise be made by Bank to
Borrowers as LIBOR Loans shall be made instead as Prime Loans. Bank shall notify
Borrowers if and when the circumstances  giving rise to such repayment no longer
apply.

                  3.13  Survival  of   Indemnities.   All  indemnities  and  all
provisions  relating to reimbursement  to Bank of amounts  sufficient to protect
the yield to Bank with  respect to the  Loans,  including,  without  limitation,
Sections  3.9,  3.10 and 3.11 hereof,  shall survive the payment of the Note and
the termination of this Agreement.

                  3.14   Discretion   of  Bank   as  to   Manner   of   Funding.
Notwithstanding any provision  contained in this Agreement to the contrary,  the
Bank shall be  entitled to fund and  maintain  its funding of all or any part of
its LIBOR Loans in any manner it elects, it being understood,  however, that for
purposes of this  Agreement all  determinations  hereunder  (including,  without
limitation,  the  determination  of Bank's  funding  losses and  expenses  under
Section 3.8) shall be made as if Bank had actually  funded and  maintained  each
LIBOR Loan through the purchase of deposits having a maturity  corresponding  to
the maturity of the applicable  Interest Period relating to the applicable LIBOR
Loan and bearing an interest rate equal to the applicable  LIBOR Base Rate. Bank
may, at its option,  elect to make,  fund or maintain its Loans hereunder at any
of its  branches or offices or at such other of its  branches or offices as Bank
may from time to time elect,  provided that the Borrowers  shall not be required
to reimburse  Bank under any of the provisions of Section 3.8 for any cost which
Bank would not have  incurred  but for  changing  its lending or funding  branch
unless Borrowers consent to such change.

                  3.15 Commitment Fee. Borrowers shall jointly and severally pay
to Bank on the fifteenth  (15th) day  following the end of each January,  April,
July and October  during the Term of this  Agreement  and on the last day of the
Term hereof, a commitment fee (the "Commitment Fee") in an amount equal to:

                  (a) One-Eighth of One Percent  (0.125%) per annum, if Virbac's
ratio of Consolidated  EBITDA to Consolidated Debt Service shall be greater than
or equal to 2.5 to 1.0 as determined  pursuant to Section 7.1(i)(i) by reference
to Virbac's most recent quarter-end (or fiscal year-end) financial statements,

                  (b)  Three-Sixteenths  of One Percent  (0.1875%) per annum, if
Virbac's  ratio of  Consolidated  EBITDA to  Consolidated  Debt Service shall be
greater  than or  equal to 2.0 to 1.0 but  less  than  2.5 to 1.0 as  determined
pursuant to Section  7.1(i)(i) by reference to Virbac's most recent  quarter-end
(or fiscal year-end) financial statements, and

                  (c) One-Fourth of One Percent  (0.25%) per annum,  if Virbac's
ratio of Consolidated  EBITDA to Consolidated Debt Service shall be greater than
or equal  to 1.25 to 1.0 but less  than  2.0 to 1.0 as  determined  pursuant  to
Section  7.1(i)(i) by reference to Virbac's most recent  quarter-end  (or fiscal
year-end)  financial  statements,  calculated  on the basis of the unused Bank's
Commitment  during the preceding  fiscal  quarter of Borrowers  ending as of the
last  day of  each  January,  April,  July  and  October,  which  unused  Bank's
Commitment  shall be arrived at by dividing  the  aggregate  of the daily unused
Bank's  Commitment  for each day of that  quarter as of the close of each day by
ninety (90) (or by the actual number of days for any partial  quarter).  Payment
of the Commitment Fee is a condition precedent to Bank's obligations to make any
new Loans hereunder.

                  3.16  Maturity.  All  Loans not paid  prior to July 31,  2002,
together with all accrued and unpaid interest thereon,  shall be due and payable
on July 31,  2002 (as  from  time to time  extended,  if any,  pursuant  to this
Section, the "Maturity Date"); provided, however, that in the event Bank, in its
sole and absolute discretion, shall deliver to Borrowers a written notice signed
by Bank on or before the date one year prior to the then current  Maturity  Date
(and prior to any  subsequent  Maturity Date  thereafter if extended  under this
Section  3.16) of Bank's  intention to extend the term of this  Agreement for an
additional  year, then the Maturity Date of this Agreement shall be extended for
a period of one  additional  year  following  the then  current  Maturity  Date.
Following  any  such  extension  of  the  Maturity  Date  by  Bank,  all  of the
outstanding  principal  and all  accrued  and  unpaid  interest,  fees and other
amounts due under this  Agreement  and the Note shall be due and payable on such
new Maturity Date, unless it is again extended by Bank, in its sole and absolute
discretion, under the foregoing sentence.

property and improvements.  PM Resources further covenants and agrees to execute
and deliver to Bank any and all amendments,  including,  without limitation, the
Amendment, and such other documentation as may be requested by Bank from time to

that certain Agreement of Pledge made by Virbac in favor of Bank dated as of the
date  hereof,  and  Virbac AH has  pledged  to Bank and  granted to Bank a first
perfected  security interest in all of the issued and outstanding  capital stock

                  Borrowers represent and warrant to Bank that:

incorporation;  (b) has all requisite  corporate powers and all governmental and

         evidence of the payment of all premiums therefor.

                  (e) Accountant. Borrowers shall give Bank prompt notice of any
change of Borrowers' independent certified public accountants and a statement of
the reasons for such change.  Borrowers  shall at all times utilize  independent
certified  public  accountants  of  nationally  recognized  standing  reasonably
acceptable to Bank.

                  (f)  ERISA  Compliance.   If  any  of  the  Borrowers  or  any
Subsidiary  of any of the Borrowers  shall have any Pension Plan,  such Borrower
and/or such Subsidiary or Subsidiaries of any of the Borrowers shall comply with
all requirements of ERISA relating to such plan. Without limiting the generality
of the  foregoing,  none  of the  Borrowers  nor  any  Subsidiary  of any of the
Borrowers shall:

                           (i)  permit  any  Pension  Plan  maintained  by it to
         engage  in any  nonexempt  "prohibited  transaction,"  as such  term is
         defined in Section 4975 of the Code;

                           (ii)  permit any  Pension  Plan  maintained  by it to
         incur any "accumulated funding deficiency",  as such term is defined in
         Section 302 of ERISA, 29 U.S.C. ss. 1082, whether or not waived;

                           (iii)  terminate  any such  Pension  Plan in a manner
         which could result in the  imposition  of a Lien on any Property of any
         of the Borrowers or any Subsidiary of any of the Borrowers  pursuant to
         Section 4068 of ERISA, 29 U.S.C. ss.1368; or

                           (iv)  take  any  action  which  would   constitute  a
         complete or partial  withdrawal  from a  Multiemployer  Plan within the
         meaning of Sections 4203 and 4205 of Title IV of ERISA.

                  Notwithstanding any provision contained in this Section 7.1(f)
to the contrary,  an act by any of the Borrowers or any Subsidiary of any of the
Borrowers  shall not be deemed to  constitute a violation of  subparagraphs  (i)
through  (iv) hereof  unless  Bank  determines  in good faith that said  action,
individually  or  cumulatively  with other acts of any of the  Borrowers and the
Subsidiaries  of any of the  Borrowers,  does  have  or is  likely  to  cause  a
significant adverse financial effect upon any of the Borrowers or any Subsidiary
of any of the Borrowers.

                  Borrowers shall have the affirmative  obligation  hereunder to
report to Bank any of those acts  identified in  subparagraphs  (i) through (iv)
hereof,  regardless of whether said act does or is likely to cause a significant
adverse  financial  effect upon any of the Borrowers or any Subsidiary of any of
the  Borrowers,  and failure by Borrowers  to report such act promptly  upon any
such  Borrower's  becoming  aware of the existence  thereof shall  constitute an
Event of Default hereunder.

                  (g)  Maintenance  of Books and Records.  Each of the Borrowers
and each  Subsidiary of any of the Borrowers will maintain its books and records
in accordance with Generally Accepted Accounting Principles consistently applied
and in which  true,  correct  and  complete  entries  will be made of all of its
dealings and transactions.

                  (h) Further Assurances. Each of the Borrowers will execute any
and all further  agreements,  documents  and  instruments,  and take any and all
further  actions which may be required under  applicable  law, or which Bank may
from time to time reasonably  request,  in order to effectuate the  transactions
contemplated by this Agreement,  the Note, the Security Agreements,  the Deed of
Trust, the Letter of Credit Applications and the other Transaction Documents.

acquisition,   and  provided  further  that  all  of  the  accounts  receivable,
Inventory,  equipment,  general  intangibles  and other assets of such  acquired
Person  shall  be  pledged  as  collateral  to Bank for  Borrowers'  Obligations
hereunder in a manner  satisfactory  to Bank and if such  acquired  Person is to

hereunder,  and (ii) Borrowers project that they shall remain in compliance with
each of the  financial  covenants  contained in Section  7.1(i) herein after any

(less the number of shares  repurchased  between December 12, 1995 and September
7, 1999) of its capital stock on the open market  pursuant to that certain share
repurchase   program  outlined  to  Bank  in  a  letter  from  Virbac  (formerly

$4,185,000  of  shares of its  issued  and  outstanding  Common  Stock  upon the

contribution to Virbac in exchange for a number of newly issued shares of Virbac
equal to such capital contribution divided by the repurchase price.

                  (h) Transactions  with Related Parties.  None of the Borrowers
nor any Subsidiary of any of the Borrowers will, directly or indirectly,  engage
in any material  transaction,  in the ordinary  course of business or otherwise,
with any Related Party unless such transaction is upon fair market terms, is not
disadvantageous  in any  material  respect  to Bank and has been  approved  by a
majority of the  disinterested  directors of such Borrower or such Subsidiary of
any of the  Borrowers,  as the case may be (or,  if none of such  directors  are
disinterested,  by a majority of the directors),  as being in the best interests
of such Borrower or such Subsidiary of any such Borrower, as the case may be. In
addition, none of the Borrowers nor any Subsidiary of any of the Borrowers shall

such  other  Obligor,  as the  case  may be,  for  borrowed  money  (other  than
Borrowers' Obligations) in a principal amount in excess of Five Hundred Thousand
Dollars  ($500,000.00),  if the effect of such failure or default is to cause or

be immediately due and payable, without presentment,  demand, protest or further
notice of any  kind,  all of which are  hereby  expressly  waived by each of the
Borrowers,  and Bank may exercise any and all other rights and remedies which it
may have under any of the other  Transaction  Documents or under applicable law;
provided,  however,  that upon the occurrence of any event described in Sections

automatically  terminate and the entire outstanding principal balance of and all
accrued  and  unpaid  interest  on the  Note  and  all of the  other  Borrowers'
Obligations  shall  automatically  become  immediately due and payable,  without
presentment,  demand,  protest or further  notice of any kind,  all of which are
hereby expressly waived by each of the Borrowers,  and Bank may exercise any and
all  other  rights  and  remedies  which  it may  have  under  any of the  other
Transaction Documents or under applicable law.

SECTION 9.  GENERAL.

                  9.1 No Waiver.  No failure or delay by Bank in exercising  any
right,  remedy,  power or  privilege  hereunder  or under any other  Transaction
Document  shall  operate  as a waiver  thereof;  nor shall any single or partial
exercise  thereof preclude any other or further exercise thereof or the exercise
of any other right, remedy, power or privilege. The remedies provided herein and
in the other  Transaction  Documents  are  cumulative  and not  exclusive of any
remedies  provided by law.  Nothing herein contained shall in any way affect the
right of Bank to exercise any  statutory or common law right of banker's lien or
setoff.

                  9.2  Right of  Setoff.  Upon the  occurrence  and  during  the
continuance of any Event of Default,  Bank is hereby  authorized at any time and
from time to time,  without notice to Borrowers (any such notice being expressly
waived by each of the Borrowers) and to the fullest extent  permitted by law, to
setoff  and apply any and all  deposits  (general  or  special,  time or demand,
provisional  or  final)  at any  time  held  by  Bank  and  any  and  all  other
indebtedness at any time owing by Bank to or for the credit or account of any of
the Borrowers  against any and all of  Borrowers'  Obligations  irrespective  of
whether or not Bank shall  have made any  demand  hereunder  or under any of the
other  Transaction  Documents and although such obligations may be contingent or
unmatured.  Bank agrees to promptly  notify  Borrowers after any such setoff and
application  made by Bank,  provided,  however,  that the  failure  to give such
notice shall not affect the validity of such setoff and application.  The rights
of Bank under this  Section 9.2 are in addition to any other rights and remedies
(including,  without  limitation,  other rights of setoff)  which Bank may have.
Nothing  contained in this  Agreement or any other  Transaction  Document  shall
impair the right of Bank to exercise any right of setoff or  counterclaim it may
have  against  any of the  Borrowers  and to apply the  amount  subject  to such
exercise to the payment of  indebtedness  of any of the  Borrowers  unrelated to
this Agreement or the other Transaction Documents.

                  9.3 Cost and Expenses.  Borrowers jointly and severally agree,
whether  or not any Loan is made  hereunder,  to pay Bank  upon  demand  (i) all
out-of-pocket  costs and expenses and all Attorneys'  Fees of Bank in connection
with the preparation,  documentation,  negotiation, execution and administration
of this  Agreement,  the  Note and the  other  Transaction  Documents,  (ii) all
recording,  filing,  title  insurance,  surveying and appraisal fees incurred in
connection with this Agreement and the other  Transaction  Documents,  (iii) all
out-of-pocket  costs and expenses and all Attorneys'  Fees of Bank in connection
with the preparation of any waiver or consent  hereunder or any amendment hereof
or any Event of Default or alleged Event of Default hereunder,  (iv) if an Event
of Default occurs, all out-of-pocket  costs and expenses and all Attorneys' Fees
incurred by Bank in  connection  with such Event of Default and  collection  and
other enforcement  proceedings  resulting therefrom and (v) all other Attorneys'
Fees incurred by Bank  relating to or arising out of or in connection  with this
Agreement or any of the other Transaction  Documents.  Borrowers further jointly
and severally  agree to pay or reimburse Bank for any stamp or other taxes which
may be payable with respect to the execution,  delivery, recording and/or filing
of this Agreement,  the Note, the Security Agreements,  the Deed of Trust or any
of the other  Transaction  Documents.  All of the obligations of Borrowers under
this  Section 9.3 shall  survive  the  satisfaction  and  payment of  Borrowers'
Obligations and the termination of this Agreement.

                  9.4  Environmental  Indemnity.  Borrowers  hereby  jointly and
severally  agree to indemnify  Bank and hold Bank  harmless from and against any
and all losses,  liabilities,  damages,  injuries, costs, expenses and claims of
any and every kind whatsoever  (including,  without limitation,  court costs and
Attorneys' Fees) which at any time or from time to time may be paid, incurred or
suffered by, or asserted  against,  Bank for,  with respect to or as a direct or
indirect  result of the violation by any of the  Borrowers or any  Subsidiary of
any of the  Borrowers  of any  Environmental  Laws;  or with respect to, or as a
direct or indirect result of the presence on or under,  or the escape,  seepage,
leakage, spillage,  discharge,  emission or release from, properties utilized by
any of the  Borrowers  and/or  any  Subsidiary  of any of the  Borrowers  in the
conduct of their respective  businesses into or upon any land, the atmosphere or
any  watercourse,  body of water or wetland,  of any Hazardous  Materials or any
other  hazardous or toxic waste,  substance or  constituent  or other  substance
(including,  without limitation,  any losses,  liabilities,  damages,  injuries,
costs, expenses or claims asserted or arising under the Environmental Laws); and
the provisions of and undertakings and  indemnification  set out in this Section
9.4 shall survive the satisfaction and payment of Borrowers' Obligations and the
termination of this Agreement.

                  9.5 General Indemnity.  In addition to the payment of expenses
pursuant to Section 9.3,  whether or not the  transactions  contemplated  hereby
shall be consummated, Borrowers hereby jointly and severally agree to indemnify,
pay and hold Bank and any holder(s) of the Note,  and the  officers,  directors,
employees,  agents and affiliates of Bank and such holder(s) (collectively,  the
"Indemnitees")  harmless  from  and  against  any  and  all  other  liabilities,
obligations,  losses, damages,  penalties,  actions,  judgments,  suits, claims,
costs,  expenses and disbursements of any kind or nature whatsoever  (including,
without  limitation,  the reasonable fees and  disbursements of counsel for such
Indemnitees in connection  with any  investigative,  administrative  or judicial
proceeding  commenced or threatened,  whether or not such  Indemnitees  shall be
designated  a party  thereto),  that may be imposed on,  incurred by or asserted
against  the  Indemnitees,  in any manner  relating  to or  arising  out of this
Agreement,  any of the  other  Transaction  Documents  or any  other  agreement,
document or  instrument  executed and  delivered by any of the  Borrowers or any
other Obligor in connection herewith or therewith,  the statements  contained in
any commitment  letters  delivered by Bank,  Bank's  agreement to make the Loans
hereunder  or the use or  intended  use of the  proceeds  of any Loan  hereunder
(collectively,  the  "indemnified  liabilities");  provided that Borrowers shall
have no  obligation  to an  Indemnitee  hereunder  with  respect to  indemnified
liabilities  arising from the gross  negligence  or willful  misconduct  of that
Indemnitee  as determined  by a court of competent  jurisdiction.  To the extent
that the  undertaking  to  indemnify,  pay and hold  harmless  set  forth in the
preceding  sentence may be  unenforceable  because it is violative of any law or
public  policy,  each Borrower shall  contribute the maximum  portion that it is
permitted  to  pay  and  satisfy  under   applicable  law  to  the  payment  and
satisfaction of all indemnified  liabilities  incurred by the Indemnitees or any
of them. The provisions of the undertakings and  indemnification set out in this
Section 9.5 shall survive satisfaction and payment of Borrowers' Obligations and
the termination of this Agreement.

                  9.6  Authority  to Act.  Bank shall be  entitled to act on any
notices and instructions  (telephonic or written) reasonably believed by Bank to
have been  delivered  by any  person  authorized  to act on behalf of any of the
Borrowers pursuant hereto,  regardless of whether such notice or instruction was
in fact delivered by a person  authorized to act on behalf of any such Borrower,
and Borrowers hereby jointly and severally agree to indemnify Bank and hold Bank
harmless from and against any and all losses and expenses,  if any, ensuing from
any such action.

                  9.7   Notices.   Any   notice,   request,   demand,   consent,
confirmation or other communication  hereunder shall be in writing and delivered

                  9.8 CONSENT TO  JURISDICTION;  JURY TRIAL WAIVER.  EACH OF THE
BORROWERS  IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE  JURISDICTION OF ANY MISSOURI
STATE  COURT OR ANY  UNITED  STATES OF  AMERICA  COURT  SITTING  IN THE  EASTERN

SUCH  SUIT,  ACTION  OR  PROCEEDING  MAY BE HELD AND  DETERMINED  IN ANY OF SUCH

PERMITTED BY LAW, ANY OBJECTION WHICH SUCH BORROWER MAY NOW OR HEREAFTER HAVE TO

COURT, AND EACH OF THE BORROWERS FURTHER  IRREVOCABLY WAIVES ANY CLAIM THAT SUCH
SUIT,  ACTION OR  PROCEEDING  BROUGHT IN ANY SUCH  COURT HAS BEEN  BROUGHT IN AN
INCONVENIENT  FORUM. EACH OF THE BORROWERS HEREBY EXPRESSLY WAIVES ALL RIGHTS OF
ANY OTHER  JURISDICTION  WHICH SUCH BORROWER MAY NOW OR HEREAFTER HAVE BY REASON
OF ITS PRESENT OR SUBSEQUENT  DOMICILES.  EACH OF THE BORROWERS  AUTHORIZES  THE
SERVICE OF PROCESS UPON SUCH  BORROWER BY  REGISTERED  MAIL SENT TO BORROWERS AT
THEIR ADDRESS SET FORTH IN SECTION 9.7. EACH OF THE BORROWERS  HEREBY WAIVES ANY
RIGHT  TO  TRIAL BY JURY OF ANY  LITIGATION  BROUGHT  IN  ACCORDANCE  WITH  THIS
SECTION.

                  9.9 Bank's Books and Records. Bank's books and records showing
the account  between  Borrowers  and Bank shall be admissible in evidence in any
action or proceeding and shall constitute prima facie proof thereof.  Bank shall
record,  and prior to any  transfer  of any of its Notes  shall  endorse  on the
schedules forming a part thereof, appropriate notations to evidence (i) the date
and amount of each  conversion  of any portion of any Facility B Loan to a LIBOR
Loan  and the  principal  amount,  applicable  LIBOR  Rate,  and the  applicable
Interest  Period  with  respect  thereto,  and (ii) the date and  amount of each
payment of principal made by Borrowers  with respect to each such Loan.  Bank is
hereby irrevocably  authorized by Borrowers so to endorse its Note and to attach
to and make a part of such Note a continuation  of any such schedule as and when
required;  provided, however that the joint and several obligations of Borrowers
to repay the Loans made by Bank hereunder  shall be absolute and  unconditional,
notwithstanding  any  failure  of  Bank to  endorse  or any  mistake  by Bank in
connection with endorsement on the schedules attached to its Note.

                  9.10 Governing Law; Amendments.  This Agreement, the Note, the

                                                     Litigation


1.       In March 1998, a claim was filed against the Company and certain of its
         subsidiaries  alleging breach of an implied  employment  contract.  The
         amount  of  claims  identified  in  the  motion  totaled  approximately
         $150,000,   plus  certain  unspecified  damages.   Management  and  the
         Company's  counsel expect that final resolution of this action will not
         have a material impact upon the Company's financial position or results
         of operations.

2.       In 1998,  and  Derivates  Belgium  (EDB) filed a claim  against St. JON

         license  agreement  between  St.  JON and EDB and  infringed  on  EDB's
         trademarks.   The  amount  of  claims  identified  total  approximately
         $500,000, plus certain unspecified damages. In addition, EDB is seeking
         an  injunction  on the sale of  Prozym  canine  toothpaste  in  France.
         Management and the Company's  counsel  expect that final  resolution of

         position or results of operations.

3.   In April 1998,  a claim was filed  against PM  Resources,  Inc. for damages
     alleged to have  occurred  related to a product  recall in  November  1995.
     Prior claims  related to this incident had been  submitted to the Company's
     insurance company and had been settled.  The amount of claims identified in
     this motion  totaled  approximately  $38,000.  Management and the Company's
     counsel  expect  that final  resolution  of this  action will be not have a

     operations.

4.       See  Schedule  6.17 for a  description  of a  Notice  of Order to Abate
         Violations  and a Notice of  Violations  issued to PM  Resources by the

         $45,000.00, plus certain unspecified damages. Management and Borrowers'
         counsel  expect  that final  resolution  of this action will not have a
         material  impact  upon  Virbac's   financial  position  or  results  of
         operations.

         earnings  before  taxes and  interest  for the five year period  ending
         October  31, 1999 which are in excess of a  specified  base.  As of the
         date hereof, no such additional payments are due. Furthermore, based on

         such agreements.

         Inc. In connection with the  acquisition,  Virbac issued a note payable
         of  $300,000  to the  former  owners of  Mardel,  $147,000  of which is
         payable in cash and $153,000 of which is payable in Virbac stock over a
         period of three years.

         Generale. This amount will be repaid on September 7, 1999 using part of
         the  proceeds  from  this  Agreement,  and the line of  credit  will be
         closed.

                                                    SCHEDULE 6.17

                                     Environmental and Health and Safety Matters


1.   On November 27, 1994, the MDNR issued a Notice of Order to Abate Violations
     to PM  Resources  relating to alleged  violations  of  Missouri's  laws and
     regulations  relating to the storage of  hazardous  waste at the  Bridgeton
     facility.  The order  alleges  that PM Resources  had not remedied  certain
     deficiencies   relating  to  the  storage  of  hazardous   waste  cited  in
     inspections  by the MDNR in May 1993 and March 1994,  and directs  remedial
     action.

2.   On  December  21,  1995,  the  MDNR  issued a Notice  of  Violations  to PM
     Resources  relating to  contamination  in the  vicinity  of an  underground
     collection system that was removed from the Bridgeton facility in 1994. The
     notice alleges that the collection  system should have been included in the
     Company's hazardous waste storage permit, states that the collection system
     was  classified  by the MDNR as a leaking  underground  storage  tank,  and
     directs remedial action.

3.   Virbac is currently in negotiations with the MDNR related to certain issues
     raised in the November,  1994 Notice of Order to Abate  Violations  and the
     December 1995 Notice of Violations issued by the MDNR.  Management does not
     believe that either of the matters pose a significant  risk to human health
     or the environment,  or that the resolution of either of the claims made by
     the MDNR will have a material adverse effect on Virbac's financial position
     or results of operations.
