1.     Unaudited consolidated financial statements

              The   consolidated   balance  sheet  as  of  July  31,  1997,  the
       consolidated  statements  of  operations  for the  three  and  nine-month
       periods ended July 31, 1996 and 1997, the consolidated statements of cash
       flows for the  nine-month  periods  ended July 31,  1996 and 1997 and the
       consolidated  statement of shareholders' equity for the nine-month period
       ended July 31, 1997 have been  prepared by  Agri-Nutrition  Group Limited
       ("the  Company")  without  audit.  In  the  opinion  of  management,  all
       adjustments (which include only normal,  recurring adjustments) necessary
       to present fairly the financial position,  results of operations and cash
       flows at and for the periods ended July 31, 1996 and 1997 have been made.

              Certain information and footnote  disclosures normally included in
       financial  statements  prepared in  accordance  with  generally  accepted
       accounting  principles have been condensed or omitted where inapplicable.
       The results of  operations  for the periods ended July 31, 1996 and 1997,
       respectively, are not necessarily indicative of the operating results for
       the full year.

              The  consolidated  financial  statements  have  been  restated  to
       reflect the Company's Ingredients segment as a discontinued  operation in
       accordance with Accounting Principles Board Opinion No.
       30 ("APB 30") (see Note 3).

2.     Organization

              Organized in 1993, the Company manufactures and distributes animal
       health and pet care products. In September 1993, through its wholly-owned
       subsidiary,  PM  Resources,  Inc.  ("Resources"),  the  Company  acquired
       certain assets and assumed certain  liabilities of the Health  Industries
       Business of the Consumer  Products  Division (the  "Business")  of Purina
       Mills, Inc.  ("Purina").  Resources commenced  operations on September 9,
       1993,  the effective date of the  acquisition of the Business.  Resources
       formulates,    manufactures   and   distributes   medicated   treatments,
       anthelmetics,  nutritional supplements,  cleaners and disinfectants, pest
       control  products,   home,  lawn  and  garden  products,   and  specialty
       compounds.

             Effective March 31, 1995, the Company  purchased  substantially  
       all of the net assets and business of Zema Corporation ("Zema"). The 
       Company also purchased substantially all of the net assets and business 
       of St. JON  Laboratories,  Inc. ("St.  JON")  effective  August 31, 1995.
       Zema and St. JON formulate,  package, market  and  distribute  pet health
       care,  veterinary  and  grooming  products domestically and abroad.

              See  Note 3 to the  Company's  Consolidated  Financial  Statements
       included in the  Company's  annual  report to  shareholders  for the year
       ended October 31, 1996 ("1996 Annual Report") for additional  information
       related to the  acquisitions of Zema and St. JON,  including  information
       regarding the additional  purchase price which must be paid to the former
       owner of Zema if Zema achieves certain financial goals. In addition,  see
       Note 4 to the Company's Consolidated Financial Statements included in the
       1996 Annual Report for information about the Company's acquisition of the
       worldwide patents, active ingredient inventory,  registrations and rights
       to  Bromethalin  (the  "Bromethalin  Assets"),  a  highly  effective  and
       proprietary  rodenticide  serving  agricultural and Pest Control Operator
       (PCO) markets,  including information regarding additional  consideration
       to be paid based on shipments of  Bromethalin  to Purina over a five-year
       period.

3.     Discontinued operations

              In June  1997,  Purina  notified  the  Company  that they would no
       longer  require the  Company's  services  to  distribute  ingredients  to
       Purina's  various  plants.  Consequently,   in  July  1997,  the  Company
       distributed  all of its remaining  ingredients  inventories to Purina and
       discontinued  its operations in this area.  This segment of the Company's
       business has been accounted for and presented as a discontinued operation
       in accordance with APB 30 for all periods  reflected  herein. At July 31,
       1997,  substantially  all of the net assets  relating to the  Ingredients
       segment  have  either  been  disposed  or have  been  deployed  into  the
       Company's existing operations.

              Management does not anticipate  that the Ingredients  segment will
       have any significant  operations in the future.  Furthermore,  management
       does not believe that there are any separately  identifiable fixed assets
       related to the  Ingredients  segment  and  proceeds,  if any,  related to
       disposition  of such net assets  subsequent to the June 1997  measurement
       date will not  result in a material  net gain or loss in future  periods.
       However,  the ultimate  financial  impact of the  discontinuation  of the
       segment could differ from management's current estimates.

              The operating  (unaudited) results of the discontinued  operations
       are summarized as follows:

             The  accounting  policies  followed by the Company are set forth in
       Note 6 to the  Consolidated  Financial  Statements  included  in the 1996

             Net loss per common and common equivalent share is calculated based
       on the weighted  average  number of common and common  equivalent  shares
       outstanding  during  the  periods  presented,  using the  treasury  stock
       method.  The calculation does not reflect common stock equivalent  shares
       when their inclusion in such calculation would have been anti-dilutive.

5.     Inventories

             Inventories of the Company's  specialty products segment consist of
       the following:

                                              October 31,           July 31,

6.     Financing

              The Company  has  revolving  credit  facilities  which  aggregated
       $8.125 million at July 31, 1997. In June 1997,  the Company  modified its
       existing  credit  agreements  increasing the aggregate lines by $650,000,
       extending  their  maturity  dates  through  March 31, 1999,  lowering the
       interest  rates and commitment  fees charged and revising  certain of the
       debt covenant  calculations.  The amended  facilities consist of up to an
       aggregate of $4.8 million in revolving credit lines, the available amount
       being based upon specified  percentages of qualified accounts  receivable
       and inventory,  and a $3.35 million  revolving credit line with available
       amounts being reduced $125,000 per quarter.  The interest rate will range
       from prime minus .25% to prime plus .5%, depending on the Company's ratio
       of debt to net worth, as defined in the agreements. At July 31, 1997, the
       interest rate charged on borrowings outstanding under the agreements,  as
       amended,  was 8.50%  which is the bank's  prime rate.  At July 31,  1997,
       approximately  $2.5 million is available for additional  borrowings under
       these facilities.

              At  July  31,  1997,  the  Company  and its  subsidiaries  were in
       compliance   with  all  covenants   related  to  its  various   financing
       arrangements.

              In April 1997,  the Company  restructured  its debt agreement with
       the former owner of St. JON, who is the  president of the  Company's  St.
       JON subsidiary. Under the revised agreement, the Company paid $500,000 in
       April 1997, in addition to the $450,000 scheduled  payment,  and will pay
       off  the  remaining  amounts  in five  annual  installments  of  $324,563
       beginning in March 1998.  The  interest  rate on the note was not revised
       and is fixed at 7.6% per annum.

7.     Related Party Transactions

              See Note 13 to the Company's  Consolidated Financial Statements in
       the  1996  Annual  Report  for  a  discussion   regarding  related  party
       transactions.

8.     Employee benefit plans

              During the nine months  ended July 31,  1997,  options to purchase
       12,000 shares of the Company's  common stock were granted to employees in
       connection  with the Company's  1996  Incentive  Stock Plan. The exercise
       prices of the  options  ranged  from  $1.1875 to $1.375 per share,  which
       approximated  the fair value on the dates of grant.  These  options  vest
       ratably over three years from the date of grant and will expire ten years
       from the grant date. No shares or options were issued in connection  with
       1995 Incentive Stock Plan or the Company's 1994 Incentive Stock Plan. See
       Note 12 to the Company's  financial  statements in the 1996 Annual Report
       for a discussion of the Company's incentive stock plans.

9.     Commitments and contingencies

              From time to time, the Company becomes party to various claims and
       legal actions arising during the ordinary course of business.  Management
       believes that the Company's costs and any potential  judgments  resulting
       from such claims and  actions  will be covered by the  Company's  product
       liability insurance, except for deductible limits. The Company intends to
       defend such claims and actions in  cooperation  with its insurers.  It is
       management's  opinion that, in any event,  their outcome would not have a
       material  effect  on the  Company's  financial  position  or  results  of
       operations. See Note 6 to the Company's Consolidated Financial Statements
       in the 1996 Annual Report for a discussion of the Company's environmental
       policy.

10.    Acquisitions

       Mardel Laboratories Letter of Intent

              In July  1997,  the  Company  entered  into a letter  of intent to
       acquire Mardel Laboratories, Inc., a private company that is a developer,
       manufacturer  and  marketer  of high  quality  care  products  to the pet
       industry.  Mardel's  expertise  extends to fresh  water and marine  fish,
       birds,  dogs, cats, small animals and pond accessories.  Mardel had sales
       of  approximately  $7.6 million for the year ended December 31, 1996. The
       transaction is subject to completion of due diligence and  negotiation of
       a definitive  agreement.  Management expects that the purchase price will
       be paid with cash and  common  stock,  the cash  portion of which will be
       funded by a combination of bank financing and available funds. Management
       expects the transaction to be completed by September 30, 1997.

       Termination of Anthony Products Letter of Intent

               In March  1997,  the  Company  terminated  its  letter  of intent
       related to its  proposed  acquisition  of Anthony  Products  Company.  In
       conjunction  with this action,  the Company  recorded a $202,000  pre-tax
       charge in the second  quarter of fiscal 1997.  Such amount is included in
       other income  (expense)  in the  accompanying  consolidated  statement of
       operations.  Net income  excluding the impact of this charge for the nine
       month period ended July 31, 1997 would have been approximately $174,000.

Overview

       Organized in 1993, the Company manufactures and distributes animal health
and pet care products. In September 1993, the Company, through its PM Resources,
Inc. subsidiary ("Resources"), acquired the Health Industries Business of Purina
Mills,  Inc.  which  formulates,  manufacturers  and  distributes  animal health
products and to a lesser extent,  home, lawn and garden, and other products.  In
July 1994,  the Company  completed its initial  public  offering of Common Stock
("IPO"),  the net proceeds of which were approximately $12.1 million.  Effective
March 31, 1995, the Company  purchased  substantially  all of the net assets and
business of Zema Corporation  ("Zema"), a formulator,  manufacturer and supplier
of health care and grooming  products to the pet industry.  Effective August 31,
1995, the Company purchased  substantially all of the net assets and business of
St. JON Laboratories,  Inc. ("St. JON"), a developer,  manufacturer and marketer
of oral hygiene, dermatological and gastrointestinal products for dogs and cats.
In July 1997,  the  Company  entered  into a letter of intent to acquire  Mardel
Laboratories,  Inc., a private  company that is a  developer,  manufacturer  and
marketer of high quality care products to the pet industry.  Mardel's  expertise
extends to fresh water and marine fish,  birds,  dogs,  cats,  small animals and
pond  accessories.  Mardel  had  sales of  approximately  $7.6  million  for the
calendar year ended December 31, 1996.  Management expects the transaction to be
completed by September 30, 1997.

       Although the focus of the Company's  business  strategy  historically has
been the  acquisition  of animal health and related  companies,  in August 1996,
management  announced the completion of the  acquisition  phase of the Company's
strategy and its increased focus on internal growth,  while continuing to pursue
strategic  acquisitions  and  alliances.  Also  announced  in August  1996 was a
management  restructuring  related to this increased  focus on internal  growth.
Management  anticipates annual savings of approximately $600,000 related to this
restructuring primarily as a result of a reduction in executive salaries.

       The Company has historically  reported certain financial  information for
two segments - ingredients and specialty  products.  Ingredients consist of feed
products that are purchased or blended by the Company and distributed for Purina
Mills (see Note 14 to the Company's  Consolidated  Financial Statements included
in the 1996 Annual  Report).  Specialty  products  consist of all other products
formulated,  manufactured,  and distributed by the Company to various customers,
including Purina Mills.  Included in the specialty products segment are sales of
private  label and branded  products  for which the Company  manufactures  goods
using registrations  and/or formulas owned by the Company, and sales of products
manufactured  under contract for which the Company  manufactures  products using
the customers' registrations and/or formulas. While the Company believes segment
data is meaningful for net sales,  the Company does not believe segment data for
costs  of  sales  and   administrative   costs  are   necessarily   relevant  to
understanding the Company's business.  Costs of sales, other than raw materials,
and administrative costs incurred in the servicing of the two segments are joint
in nature and essentially  invariable,  particularly  within the levels of sales
volume  experienced  within the reporting  periods.  The supporting  asset base,
excluding inventories, is also joint in nature.

       Given the  acquisitions  of businesses  with  branded,  consumer-targeted
products in 1995 and the continued  emphasis on growth of the specialty  product
segment,  the  significance of the  ingredients  segment has decreased in fiscal
1996 and 1997. As discussed in prior filings,  management expected this trend to
continue in the future.  In June 1997,  Purina  notified  the Company  that they
would no longer  require the  Company's  services to distribute  ingredients  to
Purina's various plants. Consequently, in July 1997, the Company distributed all
of  its  remaining  ingredients  inventories  to  Purina  and  discontinued  its
operations  in  its  ingredients  segment.  This  segment  is  accounted  for as
discontinued operations in accordance with APB 30. Accordingly,  the Company has
reported the Segment as discontinued  operations and the consolidated  financial
statements have been  reclassified to report  separately the financial  position
and  operating  results of the Segment.  The  Company's  consolidated  operating
results

for the three and nine months ended July 31, 1997 have been  restated to reflect
the Company's continuing operations related to its specialty products business.

</TABLE>

Three Months Ended July 31, 1997 Compared to Three Months Ended July 31, 1996

       Total net sales  increased  9% from $7.4  million in fiscal  1996 to $8.1
million for 1997,  reflecting  an increase in higher  margin  specialty  product
sales,  which comprise all sales from continuing  operations.  Sales of pet care
products grew 24% which is primarily attributable to the new products introduced
during  fiscal  years  1996 and  1997,  and  continued  strong  growth  from the
Company's sales and distribution operation in the United Kingdom.

       The  Company's  manufacturing  and supply  agreement  with  Purina  Mills
pursuant to which Purina Mills had  guaranteed the Company  sufficient  sales to
generate  annual income,  net of  ingredient,  direct  manufacturing,  and other
direct  costs of  approximately  $2.9  million for the  three-year  period ended
October 31, 1996 expired as of that date. Although the Company continues to have
a supply relationship with Purina Mills, there can be no assurance what level of
sales or income will be obtained in the future. Sales to Purina Mills, excluding
Ingredients  which were  discontinued  in July  1997,  were  approximately  $1.1
million for both the three months ended July 31, 1997 and 1996.

       Gross profit  increased from $2.0 million in 1996 (27.0% of net sales) to
$2.2 million in 1997 (26.9% of net sales),  primarily due to the increased sales
in 1997.

       Selling,  general and  administrative  expenses were $1.9 million in 1996
compared to $1.8  million in 1997 and  decreased  as a percent of net sales from
25.6%  in  1996  to  22.2%  in  1997.  The  decrease  in  selling,  general  and
administrative expenses as a percent of sales is primarily related to the impact
of the corporate management restructuring announced in August 1996.

       The factors  discussed above resulted in operating income from continuing
operations  of  approximately  $380,000  during the three  months ended July 31,
1997, a $280,000  improvement  compared to the operating  income from continuing
operations of approximately $100,000 in the prior year.

       Interest expense was approximately  $.15 million in 1996 and $.17 million
in 1997.

       The effective income tax rate on income from continuing operations of the
Company was approximately 38.5% for 1996 and 1997,  respectively.  The aggregate
amount  of the  deferred  tax asset  valuation  allowance  at July 31,  1997 was
approximately $.1 million.

       Net income from continuing operations for the three months ended July 31,
1997,  was $141,000  compared to a net loss from  continuing  operations for the
three months ended July 31, 1996 of $19,000.

       Ingredients  sales  increased from $1.3 million in 1996 to $.9 million in
1997.  Income  from  discontinued  operations  for  the  third  quarter  of 1997
decreased approximately $23,000 from $10,000 of net income in 1996 to a net loss
of $13,000 in 1997. This is primarily  attributable  decreased volume during the
quarter  as the  Company  distributed  its  remaining  Ingredients  inventories.
Management  does not  anticipate  any  material  gains or losses  related to the
Ingredients segment.

       Net income for the third  quarter of 1997 was  $128,000  and earnings per
common share was $0.02  compared to a net loss of $9,000 in the third quarter of
1996.

Nine Months Ended July 31, 1997 Compared to Nine Months Ended July 31, 1996

       Total net sales  increased  from $21.0  million  in fiscal  1996 to $23.4
million for 1997,  reflecting  a 12%  increase in the  Company's  higher  margin
specialty  product.  The increase in sales from the pet care businesses grew 23%
primarily  reflecting the impact of new products  introduced into the veterinary
channel  during  fiscal  1996 and 1997,  and  continued  strong  growth from the
Company's  sales and  distribution  operation  in the United  Kingdom  which was
acquired in July 1996.

       The  Company's  manufacturing  and supply  agreement  with  Purina  Mills
pursuant to which Purina Mills had  guaranteed the Company  sufficient  sales to
generate  annual income,  net of  ingredient,  direct  manufacturing,  and other
direct  costs of  approximately  $2.9  million for the  three-year  period ended
October 31, 1996 expired as of that date. Although the Company expects to have a
supply  relationship with Purina Mills,  there can be no assurance what level of
sales or income will be obtained in the future. Sales to Purina Mills, excluding
sales of Ingredients which were discontinued in July 1997,  totaled $3.4 million
for the nine months ended July 31, 1997 compared to $3.8 million during the nine
months ended July 31, 1996.

       Gross profit  increased from $5.3 million in 1996 (25.4% of net sales) to
$6.1 million in 1997 (26.0% of net sales),  primarily due to the increased sales
in 1997.

       Selling,  general and  administrative  expenses were  approximately  $5.5
million in 1996 and $5.4 million in 1997,  decreasing  as a percent of net sales
from  26.1% in 1996 to 23.1% in 1997.  The  decrease  in  selling,  general  and
administrative expenses as a percent of sales is related to the impact of

the corporate management  restructuring  announced in August 1996, combined with
decreases in expenses incurred at the operating companies.

       The factors  discussed above resulted in operating income from continuing
operations of approximately $684,000 during the nine months ended July 31, 1997,
an $820,000 improvement compared to the operating loss of approximately $136,000
in the prior year.

       Interest expense was  approximately $.3 million in 1996 and 1997, with an
increase that reflects  increased debt balances that resulted from the Company's
investment in inventory related to new product  introductions  subsequent to the
first quarter of fiscal 1996 and increased sales volume in fiscal 1997.

       In March,  1997,  the Company  terminated its letter of intent related to
its proposed  acquisition of Anthony Products Company.  In conjunction with this
action,  the Company recorded a $202,000 pre-tax charge in the second quarter of
fiscal 1997. Such amount was included in other income (expense) in the Company's
consolidated statement of operations.

       The  effective  income tax rate of the Company was 38% for 1996 and 1997.
The aggregate  amount of the deferred tax asset valuation  allowance at July 31,
1997 was approximately $.1 million.

       Net income from continuing  operations for the nine months ended July 31,
1997,  excluding the impact of the Anthony  Products  charge noted above,  would
have been $140,000,  compared to a net loss from  continuing  operations for the
nine months  ended July 31, 1996 of  $261,000.  Including  the Anthony  Products
charge, net income from continuing operations for the nine months ended July 31,
1997 was $34,000.

       Ingredients  sales  were  approximately  $5.4  million  in 1996 and 1997.
Income from  discontinued  operations  for the third  quarter of 1997  decreased
approximately  $92,000  from  $107,000  in  1996 to  $15,000  in  1997.  This is
primarily  attributable  to  decreasing  margins  from the sales of  Ingredients
compared to the prior year,  combined with decreased  volume of units shipped in
1997. In July 1997, the Company shipped its remaining  Ingredients inventory and
discontinued operations in the Segment.

       Net  income  in 1997  of  $49,000  increased  by  approximately  $200,000
compared to the net loss of $154,000 in 1996.

Liquidity and Capital Resources

       The  Company's  existing  capital  requirements  are  primarily  to  fund
equipment  purchases and working  capital  needs.  The Company's cash balance of
$1.3 million at July 31, 1997 principally  reflects  remaining net proceeds from
the IPO which are available for further acquisition funding requirements. During
April 1995,  the Company  completed  the  acquisition  of Zema,  which  required
utilization of  approximately  $3.2 million of net proceeds for the  acquisition
and related expenses in 1995 and will require additional payments of $.3 million
plus  interest  prior  to  April  1998,  and  potentially   additional  payments
conditioned  upon the  achievement of certain  operating  criteria by Zema which
would be due in April 2000. In August 1995, the Company  acquired the net assets
of St. JON, which required approximately $3.5 million of cash, the assumption of
certain  liabilities  aggregating  approximately  $1.5  million  which were paid
within four months of closing,  and an additional $2 million plus interest to be
paid in annual  installments  over six years commencing  March 31, 1997.  During
fiscal 1997, the Company utilized  approximately $1.0 million of cash related to
payment of this obligation and restructured the agreement,  with annual payments
of  $325,000  being  required  over the five years  commencing  March 31,  1998.
Effective May 1996, the Company acquired the worldwide  patents and other assets
and rights to  Bromethalin,  which  required  payments  of $1 million  including
related expenses

at closing,  and will  require  additional  consideration  based on shipments of
Bromethalin to Purina Mills over a five-year period. The Company's cash balances
continue to be invested in high-grade,  short-term interest-bearing  obligations
(primarily  discount and demand notes with  maturities  of three months or less,
and  high-grade,   corporate  bonds  and  notes)  pending  their  specific  use.
Speculative use of derivatives is prohibited by the Company's investment policy.

       In July  1997,  the  Company  entered  into a letter of intent to acquire
Mardel Laboratories,  Inc., a private company that is a developer,  manufacturer
and  marketer  of high  quality  care  products  to the pet  industry.  Mardel's
expertise  extends to fresh water and marine  fish,  birds,  dogs,  cats,  small
animals and pond accessories. Mardel had sales of approximately $7.6 million for
the  calendar  year ended  December  31,  1996.  The  transaction  is subject to
completion  of  due  diligence  and  negotiation  of  a  definitive   agreement.
Management  expects  that the  purchase  price will be paid with cash and common
stock,  the cash  portion  of which  will be  funded  by a  combination  of bank
financing and available funds.  Management expects the transaction to be 
completed by September 30, 1997.

       During  the  nine  months   ended  July  31,   1997,   the  Company  used
approximately $.6 million of cash related to continuing operations compared to a
use of cash by continuing  operations  approximated  $2.7 million in 1996.  This
reduction in cash used by  continuing  operations  in 1997  compared to 1996 was
primarily  due to  emphasis  placed on the  operating  companies  to control and
reduce  inventory  levels,  as well as  certain  changes to the  product  mix at
Resources,  including the  discontinuation  of the  Ingredients  segment,  which
decreased the required  investment  in inventory in that segment.  The Company's
inventories  from  continuing  operations  decreased  $.9  million  during  1997
compared to an increase in 1996 of $1.5 million  during the first nine months of
the prior year. The discontinuation of the ingredients segment generated cash of
$1.3 million  during the nine months  ended July 31, 1997,  compared to a use of
cash related to this  discontinued  segment of $.4 million during the comparable
period in the prior year.

       The Company has  revolving  credit  facilities  which  aggregated  $8.125
million at July 31, 1997.  In June 1997,  the Company  modified to the Company's
existing credit agreements increasing the aggregate lines by $650,000, extending
their  maturity  dates through March 31, 1999,  lowering the interest  rates and
commitment fees charged and revising certain of the debt covenant  calculations.
The  amended  facilities  consist  of up to an  aggregate  of  $4.8  million  in
revolving  credit  lines,  the  available  amount  being  based  upon  specified
percentages of qualified accounts receivable and inventory,  and a $3.35 million
revolving credit line with available amounts being reduced $125,000 per quarter.
The interest rate will range from prime minus .25% to prime plus .5%,  depending
on the Company's ratio of debt to net worth,  as defined in the  agreements.  At
July 31, 1997,  the interest  rate charged on borrowings  outstanding  under the
agreements,  as amended, was 8.50% which is the bank's prime rate. Approximately
$2.5 million is available  under these  facilities at July 31, 1997. The Company
and its subsidiaries are in compliance with all covenants related to its various
financing  arrangements.  The  agreements  allow the  Company  to sweep all cash
balances against  outstanding  borrowings,  thus reducing the Company's  overall
interest expense.

       In  December  1995,  the  Company's  board of  directors  authorized  the
repurchase of up to 500,000 shares of the Company's  Common Stock. The amount of
funds required will depend upon the actual number of shares  repurchased and the
market  price paid by the Company for those  shares.  The Company  will  utilize
available funds to implement this stock repurchase.  As of July 31, 1997, 46,850
shares had been repurchased under this program at an aggregate cost of $79,542.

       Management  believes that the Company will generally have sufficient cash
to meet the needs of the current operations for the foreseeable future from cash
flows  from  current   operations,   available  funds,  and  existing  financing
facilities.

       The Company has no plans to  significantly  increase any of its operating
subsidiaries'  plant  facilities  capacity.  Capital  expenditures  for the nine
months  ended July 31,  1997 were  approximately  $.3  million.  Future  capital
expenditures  for the  Company's  operating  subsidiaries  are not  expected  to
significantly exceed historical amounts,  which approximate current depreciation
expense.


Quarterly Effects and Seasonality

       Resources' results of operations  historically have been seasonal, with a
high percentage of its volume and earnings being generated in the second quarter
(February  through April) and a low percentage of its volume and earnings in the
fourth  quarter  (August  through  October) of the fiscal  year.  However,  such
seasonal  patterns are highly  dependent on weather,  feeding  economics and the
timing  of  customer  orders.  Furthermore,   new  business  has  not  exhibited
historical patterns,  particularly the sales of rodenticides which had tended to
be  concentrated  in the  Company's  first and fourth  quarters.  The results of
Zema's operations also historically have been seasonal with a high volume of its
sales and earnings being generated during the months of April through September.
St. JON's sales and earnings historically have not been seasonal.

New Accounting Standards

       In March 1997, the Financial  Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share" (FAS 128), which
requires  public  entities to present both basic and diluted  earnings per share
amounts  on the  face  of  their  financial  statements,  replacing  the  former
calculations of primary and fully diluted  earnings per share.  The Company will
adopt FAS 128  effective  with its fiscal 1998 first  quarter,  and  anticipates
that,  when  adopted,  FAS 128 will not have a material  effect on its  reported
earnings per common share.

<PAGE>



                           (iii)  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

                           (iv) that on the date of, and after giving effect to,
         such  Loan,  all of the  representations  and  warranties  of  Borrower
         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 Loan made to cover

later than 10:00 a.m. (St. Louis time) on the Business Day on which a Loan is to
be made. A Borrowing  Notice shall not be revocable by Borrower.  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 Borrower the Loan proceeds
in immediately  available funds not later than 2:00 p.m. (St. Louis time) on the

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 Borrower shall be bound thereby in the same manner as if such
person were actually authorized or such signature were genuine. Borrower further
requests and authorizes Bank, in Bank's sole and absolute discretion,  to make a
Loan to Borrower  hereunder at the end of each day in which  Borrower shall have
an  overdraft   (negative   balance)  in  its  operating  account  (Account  No.
9800805419)  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,  which Loan shall be in the
amount of such  overdraft  without any other request or  authorization  therefor
from Borrower and without notice to Borrower.  Similarly, Borrower requests that
Bank apply any collected balances in excess of a mutually  predetermined  amount
remaining at the end of any day in Borrower's operating account to the repayment
of the principal  balance of Borrower's  Obligations  outstanding as Loans under
the Note.  Borrower also hereby agrees 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

dated the date hereof and payable to the order of Bank in the original principal
amount of One Million Eight Hundred Thousand Dollars ($1,800,000.00) in the form

may from time to time be amended, modified, extended or renewed, the "Note").

made on a Business Day. All  prepayments  shall be applied solely to the payment
of principal.

                  3.5 Interest  Payments.  Borrower  shall pay Bank all interest

on the Loans are  payable to Bank in lawful  currency  of the  United  States in

calculated  on the basis of the unused  Bank's  Commitment  during the preceding
fiscal  quarter of Borrower  ending as of the last day of each  January,  April,

sole and absolute discretion,  shall deliver to Borrower 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  3.8) 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.

balance  sheets and their  accompanying  notes fairly  present the  condition of
Borrower and its  Consolidated  Subsidiaries as of the dates thereof;  (2) there
has been no material adverse change in the condition or operation,  financial or
otherwise,  of Borrower,  the Guarantor or any of their respective  Consolidated
Subsidiaries  since April 30, 1997; and (3) neither Borrower,  the Guarantor nor

hereto,  there is no action  or  proceeding  pending  or,  to the  knowledge  of
Borrower,  threatened  against  or  affecting  Borrower,  the  Guarantor  or any
Subsidiary  of  Borrower  or  Guarantor  before  any  court,  arbitrator  or any

any Subsidiary of Borrower or the Guarantor.

all applicable  statutes and governmental  rules and regulations;  no Reportable
Event has occurred and is continuing  with respect to any Pension Plan;  neither

as defined in Sections 4203 or 4205 of ERISA,  respectively;  no steps have been
instituted  by Borrower,  any ERISA  Affiliate or any  Subsidiary of Borrower to
terminate  any Pension  Plan; no condition  exists or event or  transaction  has
occurred in connection with any Pension Plan or  Multiemployer  Plan which could

any ERISA Affiliate nor any Subsidiary of Borrower is a  "contributing  sponsor"
as  defined  in  Section  4001(a)(13)  of ERISA of a  "single-employer  plan" as

         and which, in the good faith opinion of the management of Borrower,  is
         in the best  interests of Borrower or such  Subsidiary of Borrower,  as

Without  limiting the  generality  of the  foregoing,  neither  Borrower nor any
Subsidiary of Borrower 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
         Borrower  or any  Subsidiary  of Borrower  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 Borrower or any  Subsidiary of Borrower 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 Borrower and the  Subsidiaries  of Borrower,  does have or is
likely to cause a  significant  adverse  financial  effect upon  Borrower or any
Subsidiary of Borrower.

                  Borrower 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  Borrower or any  Subsidiary  of  Borrower,  and
failure by Borrower to report such act promptly upon  Borrower's  becoming aware
of the existence thereof shall constitute an Event of Default hereunder.

        (g)      Maintenance of Books and Records.  Borrower and each Subsidiary
of Borrower will maintain its books and records in accordance with Generally 
Accepted

preclude  Borrower  or  any  Subsidiary  of  Borrower  from  selling,   leasing,
transferring  or  otherwise  disposing  of less  than  substantially  all of its
Property  or assets so long as the  purchase  price for said  Property or assets

that  Subsidiaries  of Borrower may merge with each other or into Borrower,  and
except that Borrower or any Subsidiary of Borrower may merge with or consolidate
with any other Person  provided  that Borrower or such  Subsidiary  shall be the

         other like  advances  to  officers  and  employees  of  Borrower or any
         Subsidiary of Borrower in the ordinary course of business; and

                           (v) Make  loans from time to time to or  advances  on
         behalf of Guarantor or any other Related Party, provided, however, that
         after the occurrence of a Default or Event of Default, Borrower

         shall not make any further loan,  advance or other transfer of funds to
         or on behalf of Guarantor or any other Related Party.

     (j)      Dissolution or Liquidation.  Borrower shall not seek or permit the
dissolution or liquidation of Borrower in whole or in part.

business.

        (l)      Pension Plans.  Neither Borrower nor any Subsidiary of Borrower
shall (a) permit any  condition  to exist in  connection  with any Pension  Plan
which might  constitute  grounds for the PBGC to institute  proceedings  to have
such Pension Plan  terminated or a trustee  appointed to administer such Pension
Plan or (b) engage in, or permit to exist or occur, any other  condition,  event
or  transaction  with  respect to any  Pension  Plan which  could  result in the
incurrence by Borrower or any Subsidiary of Borrower of any material  liability,
fine or penalty.  Neither  Borrower nor any  Subsidiary of Borrower shall become
obligated to contribute to any Pension Plan or Multiemployer Plan other than any
such plan or plans in existence on the date hereof.

carrying  "margin  stock"  within the  meaning of  Regulation  U of The Board of
Governors of the Federal Reserve System, as amended.

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 Borrower (any such notice being  expressly
waived by Borrower)  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 Borrower against any and all of
Borrower's  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
Borrower 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  Borrower and to apply the
amount  subject to such  exercise  to the  payment of  indebtedness  of Borrower
unrelated to this Agreement or the other Transaction Documents.

                  9.3 Cost and  Expenses.  Borrower  agrees,  whether or not any
Loan is made hereunder, to pay Bank upon demand (i) all reasonable 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 reasonable
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  reasonable  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.
Borrower  further  agrees 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  Agreement or any of the other
Transaction Documents. All of the obligations of Borrower under this Section 9.3
shall survive the  satisfaction  and payment of Borrower's  Obligations  and the
termination of this Agreement.

                  9.4  Environmental   Indemnity.   Borrower  hereby  agrees  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


<PAGE>



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 Borrower or any  Subsidiary  of
Borrower  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 Borrower
and/or any Subsidiary of Borrower 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 Borrower's 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, Borrower hereby agrees 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 Borrower  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

maximum aggregate principal amount which Bank, cumulatively,  may be required to
have  outstanding  under  this  Facility  A at any one time shall not exceed the
lesser of (i) Three Million Dollars ($3,000,000.00),  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 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 either 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 Three  Hundred  Fifty  Thousand  Dollars
($3,350,000.00)  from the date hereof until August 31, 1997,  which amount shall
thereafter be reduced by One Hundred Twenty-Five Thousand Dollars  ($125,000.00)
on each  February  28, May 31,  August 31 and  November  30, with the first such
reduction  on August  31,  1997.  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  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.

           (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)     Fifty Percent (50%) of the Eligible Non-Chow
         Inventory of PM Resources, plus

                 (iii)  Sixty Percent (60%) of the Eligible Chow Inventory of PM
Resources, plus

                         (iv)     Thirty-Five Percent (35%) of the Eligible Zema
         Inventory

        (d)      Borrowing Base Certificate.  Borrowers shall deliver to Bank on
the date of execution  hereof (with respect to the month ended May 31, 1997) and
on the twenty-first (21st) day of each month thereafter, commencing in the month
of July,  1997, a borrowing  base  certificate in the form of Exhibit A attached
hereto and  incorporated  herein by reference (a "Borrowing  Base  Certificate")
setting forth:


<PAGE>



                        (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;

                           (iii) the difference,  if any,  between the Borrowing
         Base and the aggregate  principal amount of all outstanding  Facility A
         Loans; 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,  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 to the amount of the
Borrowing Base.

          (f)      Mandatory Repayments - Facility B.  Commencing with the first
such principal reduction on August 31, 1997, on each February 28, May 31, August
31 and November 30 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 Treasury Rate Loans,  provided,
however,  that any such  repayment of Treasury Rate Loans made on any date other
than the last day of the applicable  Interest Period for such Treasury Rate Loan
shall be subject to payment  jointly and  severally  by Borrowers of the amounts
due under Section 3.7 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 Treasury Rate Loans or vice
versa,  at any time and from time to time during the Term of this Agreement upon
timely  prior oral or written  notice  ("Borrowing  Notice")  from either of the
Borrowers to Bank specifying:



<PAGE>



                           (i) the  desired  amount  of the  Facility  A Loan or
         Facility  B Loan,  which  in the case of a  Treasury  Rate  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
         Treasury Rate, or vice versa;

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

                           (iv)  in  the  case  of a  Treasury  Rate  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  either of the  Borrowers  or the date on
         which  the new  interest  rate is to take  effect  for any  outstanding
         Facility B Loan being converted 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 PM Resources'  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  hereto as Exhibit B. 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,  or not later than 10:00 a.m. (St. Louis time)
on the third (3rd)  Business  Day prior to the  Business Day on which a Treasury
Rate Loan is to be  established.  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 either 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. In the event Borrowers shall fail to provide
a new  Borrowing  Notice with respect to any Treasury Rate Loan on or before the
third (3rd)  Business  Day prior to the end of any  Interest  Period  pertaining
thereto, then Borrowers shall have deemed to elect to convert such Treasury Rate
Loan on the last day of its Interest  Period then expiring to a Prime Loan. Each
of the Borrowers hereby authorizes Bank to reasonably rely on


<PAGE>



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 PM Resources'  operating account (Account
No.  9800802535) 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,  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  in excess of a mutually  predetermined
amount remaining at the end of any day in PM Resources' 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 the date  hereof  and  payable
jointly and severally to the order of Bank in the original  principal  amount of
Six Million Three Hundred Fifty  Thousand  Dollars  ($6,350,000.00)  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      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 either 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  Treasury  Rate  applicable  for an Interest
         Period selected by either such Borrower for such Facility B Loan in the
         Borrowing Notice applicable for such Facility B Loan.



<PAGE>



          (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.

                  3.4 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 Treasury  Rate 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 Treasury Rate Loan before the last day of its
applicable  Interest Period,  and any payments of principal of any Treasury Rate
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  3.7 below.  All
prepayments shall be applied solely to the payment of principal.

                  3.5 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 Treasury Rate Loan (a) on the fifteenth  (15th) day of
the month following the month in which such interest accrued during the Interest
Period applicable to each such Treasury Rate Loan, all interest which accrued on
such  Treasury  Rate Loan during such month or portion  thereof,  and (b) on the
last day of each such Interest  Period  applicable to a Treasury Rate Loan,  all
then accrued and unpaid interest on such Treasury Rate 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.

                  3.6 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.

                  3.7 Funding Losses.  Notwithstanding  any provision  contained
herein to the  contrary,  if  either  of the  Borrowers  makes  any  payment  of
principal  with respect to any Treasury  Rate 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 either of the  Borrowers  fails to borrow or pay any
Treasury Rate Loan after notice has been given by Borrowers in  accordance  with
Section 3.1(f), 3.2 or 3.5, 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


<PAGE>



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.

                  3.8 Facility 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 facility fee (the "Facility Fee") in an amount equal to:

             (a)      Five-Sixteenths of One Percent (0.3125%) per annum, if the
Guarantor's  ratio of consolidated  Indebtedness  to  Consolidated  Tangible Net
Worth  shall be greater  than or equal to 2.0 to 1.0 as  determined  pursuant to
Section  5.1(I) of the  Guaranty by  reference  to the  Guarantor's  most recent
quarter-end (or fiscal year-end) financial statements,

        (b)      One-Fourth of One Percent (0.25%) per annum, if the Guarantor's
ratio of consolidated  Indebtedness to Consolidated  Tangible Net Worth shall be
less  than 2.0 to 1.0 but  greater  than or  equal  to 1.0 to 1.0 as  determined
pursuant to Section 5.1(I) of the Guaranty by reference to the Guarantor's  most
recent quarter-end (or fiscal year-end) financial statements, and

     (c) Three-Sixteenths of One Percent (0.1875%) per annum, if the Guarantor's
ratio of consolidated  Indebtedness to Consolidated  Tangible Net Worth shall be
less than 1.0 to 1.0 as determined pursuant to Section 5.1(I) of the Guaranty by
reference  to the  Guarantor'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 Facility Fee is a
condition precedent to Bank's obligations to make any new Loans hereunder.

                  3.9  Maturity.  All  Loans not paid  prior to March 31,  1999,
together with all accrued and unpaid interest thereon,  shall be due and payable
on March  31,  1999 (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  3.9) 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.

                  3.10  Renewal  Fee. In  consideration  of Bank's  agreement to
extend credit  hereunder,  Borrowers  shall jointly and severally pay to Bank on
the date  hereof a renewal  fee in the  amount of Three  Thousand  Five  Hundred
Dollars ($3,500.00).

this Section 4.2.

SECTION 5.  SECURITY

                  5.1 Security  Agreements.  In order to secure the payment when

                           (ii) Do all things  necessary to preserve and keep in
         full force and effect its corporate existence, rights and franchise and
         to be duly  qualified  to do  business in all  jurisdictions  where the
         nature of its business requires such qualification;

                           (iii)  Maintain and keep its Properties as a whole in
         good repair,  working  order and  condition;  provided,  however,  that
         nothing in this  subsection  (iii) shall prevent any abandonment of any
         Property which is not  disadvantageous  in any material respect to Bank
         and  which,  in the good  faith  opinion  of the  management  of either
         Borrower,  is in the best interests of such Borrower or such Subsidiary
         of either such Borrower, as the case may be; and

                           (iv)  Insure  with  financially  sound and  reputable
         insurers  acceptable  to  Bank,  all  Property  of  Borrowers  and each
         Subsidiary of either of the Borrowers of the character  usually insured
         by  corporations  engaged in the same or similar  businesses  similarly
         situated,  against  loss or  damage  of the  kind  customarily  insured
         against by such  corporations,  unless  higher  limits or coverage  are
         reasonably  required in writing by Bank, and carry  adequate  liability
         insurance  and other  insurance  of a kind and in an  amount  generally
         carried  by  corporations  engaged  in the same or  similar  businesses
         similarly  situated,  unless higher  limits or coverage are  reasonably
         required  in  writing  by Bank.  All such  insurance  may be subject to
         reasonable  deductible amounts.  Promptly upon Bank's request therefor,
         each of the  Borrowers  shall provide Bank with evidence that each such
         Borrower maintains, and that each Subsidiary of either such


<PAGE>



         Borrower   maintains,   the  insurance   required  under  this  Section
         7.1(d)(iv), 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 either of the Borrowers or any Subsidiary
of either of the  Borrowers  shall have any Pension Plan,  such Borrower  and/or
such Subsidiary or Subsidiaries of either of the Borrowers shall comply with all
requirements of ERISA relating to such plan.  Without limiting the generality of
the  foregoing,  neither  Borrower nor any Subsidiary of either 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
         either of the  Borrowers or any  Subsidiary  of either 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 either of the Borrowers or any  Subsidiary of either
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 either of the Borrowers and the
Subsidiaries  of  either  of the  Borrowers,  does  have or is likely to cause a
significant  adverse  financial  effect  upon  either  of the  Borrowers  or any
Subsidiary of either 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 either of the  Borrowers  or any  Subsidiary  of
either of the  Borrowers,  and failure by  Borrowers to report such act promptly
upon  either 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 either of the Borrowers will maintain its books and records 
in accordance


<PAGE>



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

however,  that the foregoing  shall not preclude  either of the Borrowers or any
Subsidiary of either of the Borrowers  from selling,  leasing,  transferring  or

each  other or into  either of the  Borrowers,  and  except  that  either of the
Borrowers  or any  Subsidiary  of either  of the  Borrowers  may  merge  with or
consolidate with any other Person provided that such Borrower or such Subsidiary

of the stock or assets of any other Person upon thirty (30) days' prior  written
notice  to Bank  provided  that no  Default  or Event  of  Default  then  exists
hereunder, and provided further that all of the accounts receivable,  Inventory,
equipment, general intangibles and other assets of such acquired Person shall be

<PAGE>



Borrowers'  Obligations  hereunder in a manner  satisfactory to Bank.  Borrowers

Subsidiary of either 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
either 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 either such Borrower, as the case may be.
In addition,  neither  Borrower nor any Subsidiary of either  Borrower shall (i)
transfer  any  Property or assets to any  Related  Party for other than its fair
market  value or (ii)  purchase or sign any  agreement  to purchase any stock or
other  securities  of any Related Party  (whether  debt,  equity or  otherwise),
underwrite  or Guarantee the same, or otherwise  become  obligated  with respect
thereto.  Nothing in this Section  7.2(h) shall  prohibit  either  Borrower from

less than market value to St. JON Laboratories, Inc., St. JON VRx Products Ltd.,
Guarantor or the other Borrower hereunder.

         (i)      Loans and Investments.  Neither Borrower nor any Subsidiary of
either  Borrower  will make any loans or  advances  or  extensions  of credit to

this  Agreement  has  terminated,  whereupon  such  obligation  of Bank shall be
immediately  and forthwith  terminated,  and Bank may further declare the entire
outstanding principal balance of and all accrued and unpaid interest on the Note
and all of the other  Borrowers'  Obligations  to be forthwith  due and payable,
whereupon  all of the unpaid  principal  balance of and all  accrued  and unpaid
interest on the Note and all such other Borrowers'  Obligations shall become and
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
8.7 or  8.8,  Bank's  obligation  to  make  Loans  under  this  Agreement  shall
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 either
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 either of the Borrowers and to apply the amount subject to such


<PAGE>



exercise to the payment of indebtedness of either 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 either of the Borrowers or any Subsidiary of
either 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
either of the Borrowers  and/or any Subsidiary of either 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


<PAGE>



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 either 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 either 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  either  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,

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
