            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                            (Unaudited)

(1)  Summary of significant accounting policies

     (a) Organization

      Tripos,  Inc.  (the  "Company")  delivers  science,  tools  and
analysis services that advance customers' creativity and productivity
in  pharmaceutical, agrochemical, biotechnology and related  research
industries worldwide.  The Company is also a value-added reseller  of
third  party  hardware  products required  to  operate  its  software
products.   A  substantial  portion  of  the  Company's  business  is
conducted with pharmaceutical companies, however, the Company is  not
economically dependent on any customer on an ongoing basis.

     (b) Basis of Presentation

      The  accompanying  unaudited consolidated financial  statements
have  been  prepared in accordance with generally accepted accounting
principles   for   interim  financial  information   and   with   the
instructions  to  Form  10-Q  and  Article  10  of  Regulation   S-X.
Accordingly, they do not include all of the information and footnotes
required  by  generally accepted accounting principles  for  complete
financial  statements.   In  the opinion of  management,  all  normal
recurring  adjustments  necessary for a  fair  presentation  of  such
financial statements have been included.  Operating results  for  the
three-  and  nine-month  periods ended September  30,  1998  are  not
necessarily  indicative of the results that may be expected  for  the
year ended December 31, 1998.

(2)  Income taxes

      The  provision for income taxes is computed using the liability
method.   The  difference  between financial  statement  and  taxable
income  results  primarily  from the  use  of  different  methods  of
computing   capitalized  development  costs,  accrued  vacation   and
customer deposits.

(3)  Recent Pronouncements

      As  of  January  1, 1998, the Company adopted AICPA  SOP  97-2,
"Software  Revenue Recognition", which was effective for transactions
that  the  Company  entered  into in  1998.   Prior  years  were  not
restated.

     For annual financial reporting beginning January 1, 1998 and for
interim  reporting for years beginning January 1, 1999,  the  Company
will  adopt  the  FASB's  Financial  Accounting  Standards  No.  131,
"Disclosures about Segments of an Enterprise and Related Information"
("FAS  131").   FAS 131 superseded FASB Statement No. 14,  "Financial
Reporting of Segments of a Business Enterprise".  FAS 131 establishes
standards  for  the  way  that  public   business enterprises  report
information about operating segments  in  annual financial statements
and  requires that  those  enterprises  report  selected  information
about operating segments in  interim financial reports.  FAS 131 also
establishes  standards  for  related  disclosures about  products and
services, geographic  areas, and major  customers.  The  adoption  of
FAS 131 will not affect results of operations or financial  position,
but  will  require  additional  enterprise-wide disclosures.

      In  June 1998, the Financial Accounting Standards Board  issued
Statement No. 133, "Accounting for Derivative Instruments and Hedging
Activities"  ("FAS 133"), which is required to be  adopted  in  years
beginning after June 15, 1999.  FAS 133 permits early adoption as  of
the  beginning of any fiscal quarter after its issuance.  The Company
expects  to adopt the new Statement effective January 1,  2000.   FAS
133  will  require  the Company to recognize all derivatives  on  the
balance sheet at fair value.  The Company has not yet determined what
the effect FAS 133 will be on the earnings and financial position  of
the Company.

(4) Comprehensive Income

      As  of  January  1,  1998, the Company adopted  Statement  130,
"Reporting  Comprehensive  Income".  Statement  130  establishes  new
rules  for the reporting and display of comprehensive income and  its
components, however, the adoption of this Statement had no impact  on
the  Company's  net  income or shareholders' equity.   Statement  130
requires  foreign currency translation adjustments,  which  prior  to
adoption  were  reported  separately in shareholders'  equity  to  be
included   in  other  comprehensive  income.   Prior  year  financial
statements  have been reclassified to conform to the requirements  of
Statement 130.

      The components of comprehensive income, net of related tax, for
the  three- and nine-month periods ended September 30, 1998 and  1997
are as follows:
                           Three Months Ended  Nine Months Ended
                            Sep 30,   Sep 30,  Sep 30,  Sep 30,

  Comprehensive income (loss)$  297    $ 396   $   55   $(1,122)

      The components of accumulated other comprehensive income, net
of  related tax, at September 30, 1998 and December 31, 1997 are as
follows:
                                                  1998   1997
  Foreign currency translation adjustments       $ 499  $ 336
                                                  
  Accumulated other comprehensive income         $ 499  $ 336

(5) Earnings Per Share

The following table sets forth the computation of basic and diluted
earnings per share for the periods ended September 30, 1998 and 1997.

The  diluted per share denominator for the nine-month period  ended
September  30, 1998 excludes incremental shares of 269,585  related
to  employee stock options because of their anti-dilutive effect as
a result of the Company's net loss for the period.


Item   2. Management's Discussion and Analysis of Financial
          Condition and Results of Operations

Overview
     
     Tripos, Inc. is a leader in providing discovery services,
informatics and products for compound research to life science
organizations worldwide.

     The Company's quarterly operating results can vary significantly
depending upon such factors as the capital expenditure budgets of its
customers, lengthy sales cycles, customer selection of compounds from
our  chemical compound library, market acceptance of new products and
enhanced  versions of existing products, the timing  of  new  product
introductions  by the Company and other vendors, changes  in  pricing
policies  by  the Company and other vendors, and changes  in  general
economic  and  competitive conditions.  In  addition,  a  substantial
portion of the Company's revenues for each quarter is attributable to
a  limited number of orders and tends to be realized towards the  end
of  each quarter.  Thus, even short delays or deferrals of sales near
the  end  of  a  quarter  can cause quarterly  results  to  fluctuate
substantially.   The  Company  typically  experiences  greater  gross
margins on software licenses, consulting, and compound sales than  on
sales  of hardware.  The Company's profitability depends in  part  on
the  mix  of  its  revenue components and not  necessarily  on  total
revenues.

     The  Company's  initial  review  of  its  Year  2000  compliance
position revealed limited exposure.  A more detailed review and  test
is scheduled to occur in the upcoming quarters.  The Company provides
software licenses that are activated and remain active based  on  the
date  and  time  of  the  computer where the software  resides.   The
Company's  internally  developed products  are  presently  Year  2000
compliant.   The Company relies on the hardware suppliers to  address
any and all Year 2000 issues and provide letters of compliance to the
Company.  The total cost that the Company estimates will be spent  to
remediate  its Year 2000 issues will not be material and  should  not
affect  future financial results of operations, liquidity or  capital
resources.  At this time, the Company fully expects to be  Year  2000
compliant,  however,  it  will  remain  dependent  on  its   hardware
suppliers  to  make Year 2000 compliant equipment  available  to  its
customers.
     
     Except  for the historical information and statements  contained
in  Management's Discussion and Analysis of Financial  Condition  and
Results  of  Operations ("MD&A"), the matters and items contained  in
this   document,  including  MD&A,  contain  certain  forward-looking
statements  that  involve  uncertainties and  risks.   The  Company's
future  results could differ materially from those discussed in  this
document.    Factors  that  could  cause  a  contribution   to   such
differences, include, but are not limited to, those presented in  the
Company's Form 10-K for the year ended December 31, 1997.

Results of Operations

      Net  sales    for the third quarter of 1998 were  $5.6  million
compared  with  $9.0  million for the third  quarter  of  1997.   The
overall  decrease  in  net sales for the quarter  was  attributed  to
significant  decreases  in  the software,  hardware  and  Accelerated
Discovery Service lines.  Net sales for the first nine months of 1998
were  $17.3 million compared to $22.1 million for the same period  in
1997.   Sales  increases in software licenses and support  were  more
than  offset  by  decreases  in hardware  and  accelerated  discovery
service sales during the nine-month period.

     For the three months ended September 30, 1998, software licenses
sales  decreased 5.6% to $2.8 million.  The decrease is  due  to  the
delayed  renewal of a large wide-area network sale and the continuing
financial problems in the Pacific Rim.  For the first nine months  of
1998,  software license sales increased 2.3% to $7.1 million compared
to  the same period for 1997.  Support revenues for the third quarter
of 1998 increased 13.7% to $2.1 million from the same period in 1997.
Support  sales  increased 10.2% to $5.9 million  for  the  nine-month
period  ending  September 30, 1998.  Accelerated  discovery  services
("ADS") sales decreased 84.6% to $0.4 million in the third quarter of
1998 and 66.8% to $2.1 million for the nine-months year-to-date.  The
decrease in ADS revenue is due to production issues discussed  below.
Hardware sales decreased 80.0% to $0.3 million for the third  quarter
1998 and is attributable to the occurrence of several large orders in
the  third  quarter  of  1997.  For the first nine  months  of  1998,
hardware  sales  decreased 36.9% to $2.3 million  compared  to  1997.
Sales  to existing customers represent 84% of total revenues for  the
nine-month  period.   For  the same period,  sales  of  new  products
represent 12.4% of software license and accelerated discovery service
sales.

     In  the  second  quarter  of  1998, Tripos  introduced  its  new
LeadQuestT  library of compounds.  LeadQuest includes compounds  from
other  third-party  suppliers that meet  the  Company's  quality  and
diversity thresholds as well as newly designed compounds manufactured
at   Tripos  Receptor  Research.   The  Company  experienced  delays,
estimated to be three months, in the design and construction  of  its
new  physical laboratory facilities in England.  The first  phase  of
the  laboratory  opened  late  in the  third  quarter.   The  delayed
availability of the LeadQuest compounds has had a material impact  on
revenues  and  earnings  for  1998,  however,  orders  for  LeadQuest
compounds  were  received at the end of the quarter which  created  a
backlog of shipments of $0.6 million.
     
     In  1997,  in  response to a market demand for  highly  purified
compounds,  Tripos  and  MDS  Panlabs  invested  in  state-of-the-art
equipment  for the further analysis and purification of the Optiverse
compound   library.   The  companies  experienced   delays   in   the
purification  process  which  resulted  in  a  shortage  of  enhanced
Optiverse  compounds available for sale for the first half  of  1998.
On  March  30, 1998, the Company restructured its agreement with  MDS
Panlabs  to co-develop and market the OptiverseT library of  chemical
compounds.   Under the terms of the new agreement, MDS Panlabs  would
begin  to  market the Optiverse library.  After June  30,  1998,  MDS
Panlabs  assumed  sole  marketing  and  distribution  rights  to  the
Optiverse   compounds.   As  a  result  of  this   shift   in   their
relationship, MDS Panlabs agreed to make payments to Tripos for these
rights  and  to pay royalties on future sales of Optiverse.   In  the
second  quarter of 1998, Tripos recognized revenues for its sales  of
Optiverse compounds up to June 30th along with an initial payment for
the distribution rights.  Tripos was to then recognize royalties from
future sales of Optiverse by MDS Panlabs in the periods in which they
were to occur.  During the third quarter, the Company received a very
small  royalty payment for sales of Optiverse compounds, thus  giving
the  Company concern for MDS Panlabs' ability to market the  product.
As  a  result of this concern, the Company has accelerated its write-
down  of  remaining  capitalized costs and  the  recognition  of  the
guaranteed  income attributable to the transfer of the marketing  and
distribution rights.  This action eliminates future reliance upon MDS
Panlabs' ability to make sales of Optiverse.

      Net  sales  for the Company's activities outside North  America
represented  approximately 44.7% of total sales for  the  first  nine
months  of  1998 compared to 38.6% for the same period in 1997.   Net
sales  in  Europe increased 2.5% for the first nine  months  of  1998
compared to 1997 and accounted for 37.5% and 28.6% of total net sales
for the nine-month periods in 1998 and 1997, respectively.  Net sales
in  the Pacific Rim, principally Japan, accounted for 7.2% and  10.0%
of  total  net  sales for the first nine months  of  1998  and  1997,
respectively.

      Cost  of  sales    for  the quarter ending September  30,  1998
decreased  57.3% to $1.3 million and decreased 42.7% to $4.5  million
for  the nine-month period in 1998.  These decreases were due to  the
decreases in sales of hardware and ADS compounds.  Cost of sales as a
percent  of  net sales was 23.8% and 25.9% for the three-  and  nine-
month  periods in 1998, and 34.6% and 35.3% for the three- and  nine-
month periods in 1997, respectively.

      Gross  profit  margin percentage for the third quarter of  1998
increased to 76.2% from 65.4% in 1997.  For the first nine months  of
1998,  gross margin percentage increased to 74.1% from 64.7% for  the
same  period  in  1997.  The increase in gross margin  percentage  is
attributable  to  a  change in the sales mix  in  that  lower  margin
revenue  sources, specifically hardware and chemical compound  sales,
represented a lower percentage of total net sales in 1998 compared to
1997.

      Sales  and marketing   expenses decreased 6.8% to $2.5  million
for  the three-month period in 1998 and 1.2% to $7.3 million for  the
nine-month  period.  Sales and marketing expenses as a percentage  of
net  sales were 44.9% and 42.1% for the three- and nine-month periods
in  1998 as compared to 30.0% and 33.3% for the same periods in 1997.
The  increase in the percent to sales, for the three- and  nine-month
periods of 1998, is a function of decreased sales.

      Research and development   costs, including the costs that were
capitalized,  were $1.6 million and $2.0 million for the  three-month
periods in 1998 and 1997, $4.4 million and $5.7 million for the nine-
month  periods, respectively and represented 28.3%, 22.7%, 25.3%  and
25.7%  of  net  sales.   Research and development  expenses,  net  of
capitalized  development costs, represented 28.3% and  10.9%  of  net
sales  for  the three-month periods in 1998 and 1997, and  25.3%  and
12.4%  of  net sales for the nine-month periods ending September  30,
1998  and  1997, respectively. These decreases in gross R&D  spending
reflect a change in the treatment of compound related costs after the
restructuring  of  the  agreement  with  MDS/Panlabs.   Due  to   the
specifics  of the relationship with MDS/Panlabs, compound costs  were
capitalized  and  amortized.   However,  compounds  produced  by  the
Company  are  now reflected in inventory on a unit cost  basis.   The
increases  in  R&D  expenses  reflect  the  Company's  commitment  to
investments in new product research such as continued development  in
web-based  tools,  desktop products, diverse compound  libraries  and
combinatorial  chemistry markets.  These increases also  reflect  the
Company's investment in sponsoring drug discovery research  with  the
Wolfson  Institute (formerly the Cruciform Group) at  the  University
College of London and at Arena Pharmaceuticals, Inc.

      General and administrative  expenses decreased to $0.9  million
for  the third quarter of 1998 compared to $1.0 million in 1997,  and
represent  16.8%  and 11.3% of net sales for the respective  periods.
For  the nine-month period, G & A expenses were $2.8 million and $2.4
million in 1998 and 1997, respectively.  G&A year-to-date percent  to
net  sales was 16.2% in 1998 and 10.9% in 1997.  The increases in G&A
percent  to sales for 1998 relate to the addition of expenses related
to Tripos Receptor Research Ltd. coupled with the decline in sales.

      Other income  increased from $164,000 for the third quarter  in
1997  to  $877,000 for the comparable period in 1998.  For the  first
nine  months of 1998, other income was $1.3 million compared to  $0.4
million  in  1997.  This change was due to the addition  of  interest
expense  from the financing of the Company's headquarters acquisition
which  was offset by net rental revenues from the building's  tenants
and  recognition  of the guaranteed income from the transfer  of  the
rights to the Optiverse library from MDS/Panlabs.

      Income  tax benefit  was $108,000 for the nine-month period  in
1998  which  represents  an effective tax rate  of  36%  compared  to
$856,000  of income tax expense at a rate of 38% for the same  period
in  1997.  The Company's effective tax rate for the nine-months ended
September  30, 1998 reflects a decrease to approximate  the  expected
effective tax rate for the year ending December 31, 1998.


Liquidity, Capital Resources and Capital Commitments

      For  the nine-month period ending September 30, 1998, net  cash
provided by operations was $0.7 million as a result of a net loss  of
$0.2  million, depreciation and amortization of $3.1 million  and  an
increase  in  deferred  revenue of $1.1 million  and  a  decrease  in
accounts  receivable of $3.0 million offset by an increase  in  notes
receivable  of  $1.2  million, inventory  of  $1.4  million,  prepaid
expenses  of  $0.5  million and a decrease in  accounts  payable  and
accrued  expenses of $2.9 million. For the same period in  1997,  net
cash  provided  by operations was $4.0 million as  a  result  of  net
income  of  $1.4  million,  depreciation  and  amortization  of  $2.7
million,  an increase in accounts receivable of $0.5 million  and  an
increase in deferred revenue of $0.8 million offset by an increase in
notes  receivable of $1.1 million and a decrease in accounts  payable
and  accrued expenses of $0.3 million.  The increase in inventory  is
due  to  the  Company's  acquisition of  third  party  compounds  for
inclusion  in the LeadQuest library along with the accumulated  costs
of  producing compounds at its laboratory in England.  Raw  materials
($45,000),  work-in-process ($30,000) and finished goods ($1,826,000)
make up the total value of the Company's inventory.

     Investments of $3.0 million in property and equipment, primarily
at Tripos Receptor Research,  were partially offset by a reduction of
$1.2  million in marketable securities,  resulting in a use  of  cash
for  investing activities of approximately $1.9 million in the  first
three   quarters  of  1998.   Capitalized  development   costs   were
negligible  for  the  first nine months of 1998 as  the  Company  now
expenses  software development as incurred due to the shorter  amount
of  time  required  to  bring new products to  market  and  uses  the
inventory  accounting  method  for the  new  LeadQuestTM  library  of
compounds.   In the prior year, costs of designing and producing  the
OptiverseTM   compounds   were  capitalized   along   with   software
development.

      The  Company  believes  that current working  capital  of  $7.6
million,  together  with continued cashflow from operations  and  the
establishment of a $12 million line of credit with NationsBank,  N.A.
in  October,  1998,  will be adequate to fund liquidity  requirements
including investments in research and development, capital purchases,
primarily  related  to the construction of laboratory  facilities  at
Tripos Receptor Research in Bude, England,  and any other commitments
in the upcoming year.

3.   Lender's Commitment.
Subject to the terms and conditions hereof, and in reliance upon
the representations and warranties of Borrower herein, and the
representations and warranties of Guarantors in their Guaranty,
Lender makes the following commitment to Borrower:

     3.1. Revolving Loan Commitment.

          3.1.1. Aggregate Amount; Reductions.
     Subject to the limitations in Section 3.1.2 and elsewhere
     herein, Lender commits to make available to Borrower, from the
     Effective Date to the Revolving Loan Maturity Date a
     "Revolving Loan Commitment" of $12,000,000 by funding
     Revolving Loan Advances made from time to time by Lender as
     provided herein to accounts at Lender.  Subject to the
     limitations in Section 3.1.2 and elsewhere herein, payments
     and prepayments that are applied to reduce the Revolving Loan
     may be reborrowed through Revolving Loan Advances.  The
     Revolving Loan Commitment will reduce automatically to a
     lesser Dollar amount on certain dates as listed in the table
     below.
     
          Effective Date      Reduction      New Revolving Loan
           of Reduction                         Commitment
          October 16, 2001    $3,000,000          $9,000,000
          October 16, 2002v   $3,000,000          $6,000,000
     
     Borrower may also reduce the amount of the Revolving Loan
     Commitment in whole multiples of $100,000 at any time and from
     time to time, but only if (i) Borrower gives Lender written
     notice of Borrower's intention to make such reduction at least
     three Business Days prior to the effective date of the
     reduction, and (ii) Borrower makes on the effective date of
     the reduction any payment on the Revolving Loan required under
     Section 6.3.1 as a consequence of the reduction.  Any such
     reduction of the amount of the Revolving Loan Commitment,
     whether scheduled or voluntary, shall be permanent.

          3.1.2. Limitation on Revolving Loan Advances.
     No Revolving Loan Advance will be made which would result in
     the Revolving Loan exceeding the Maximum Available Amount and
     no Revolving Loan Advance will be made on or after the
     Revolving Loan Maturity Date.  Lender may, however, in its
     absolute discretion make Revolving Loan Advances exceeding the
     Maximum Available Amount, but shall not be deemed by doing so
     to have increased the Maximum Available Amount and shall not
     be obligated to make any such Revolving Loan Advances
     thereafter.  The "Maximum Available Amount" on any date shall
     be a Dollar amount equal to the Revolving Loan Commitment on
     such date minus the Letter of Credit Exposure on such date
     (except to the extent that such Revolving Advance will be used
     immediately to reimburse Lender for unreimbursed draws on a
     Letter of Credit.  At any time that there is an Existing
     Default, the Revolving Loan Commitment may be canceled as
     provided in Section 17.2 0.

          3.1.3. Revolving Note.
     The  obligation  of Borrower to repay Lender's Revolving  Loan
     shall  be evidenced by a promissory note payable to the  order
     of Lender in a maximum principal amount equal to the amount of
     the  Revolving  Loan Commitment and otherwise satisfactory  to
     Lender.
          
     3.2. Letter of Credit Commitment.
Lender commits to issue commercial and standby letters of credit
for the account of Borrower from time to time from the Effective
Date to the Revolving Loan Maturity Date, but only in connection
with transactions satisfactory to Lender and only if the Letter of
Credit Exposure will not as a result of such issuance exceed the
lesser of (i) $2,500,000 and (ii) any excess of the Maximum
Available Amount over the Aggregate Revolving Loan.  The expiration
date of any Letter of Credit will not be more than one year after
its issuance date and in no event will be later than the Revolving
Loan Maturity Date unless Borrower deposits with Lender cash
collateral satisfactory to Lender to secure reimbursement by
Borrower of all amounts drawn on such Letter of Credit and all
applicable fees.

4.   Interest.

     4.1. Interest on Draws on Letters of Credit.
Borrower shall pay interest on the unreimbursed amount of each draw
on a Letter of Credit at a rate per annum equal to the Prime Rate.

     4.2. Interest on Loans; Interest Periods for Eurodollar Loans.
Borrower may, as provided herein, designate each Advance or part of
an Advance to be either a Prime Rate Advance or a Eurodollar
Advance; provided, however, during the existence of an Existing
Default, Borrower may not designate an Advance or part of an
Advance as a Eurodollar Advance.  Each Prime Rate Advance when made
will become a Prime Rate Loan, which shall bear interest at the
Prime Rate (which will fluctuate as described in Section 4.6) plus
the Prime Increment (determined from time to time as provided in
Section 4.3).  Each Eurodollar Advance when made will become a
Eurodollar Loan, which shall bear interest at the Adjusted
Eurodollar Rate.  The "Adjusted Eurodollar Rate" for any Eurodollar
Loan is the Adjusted Eurodollar Base Rate (which shall be
determined before the beginning of the applicable Interest Period
as provided herein and shall apply throughout such Interest Period)
plus the applicable Eurodollar Increment (as defined below)
determined from time to time as provided in Section 4.3.  Borrower
may also, as provided herein, convert some or all of a Prime Rate
Loan into a Eurodollar Loan, and some or all of a Eurodollar Loan
into a Prime Rate Loan.  Borrower shall select an Interest Period
for each Eurodollar Loan.  Each Interest Period shall be either
one, two, three, or six months; provided that (i) every such
Interest Period shall commence on the date of the Advance; (ii) if
any Interest Period would otherwise expire on a day of a calendar
month which is not a Business Day, then such Interest Period shall
expire on the next succeeding Business Day in that calendar month;
provided, however, that if the next succeeding Business Day would
be in the following calendar month, it shall expire on the first
preceding Business Day; (iii) any Interest Period that begins on
the last Business Day of a calendar month (or on a day for which
there is no numerically corresponding day in the calendar month at
the end of such Interest Period) shall end on the last Business Day
of a calendar month; and (iv) no Interest Period shall extend
beyond the Revolving Loan Maturity Date.  A Eurodollar Loan shall
bear interest at the Adjusted Eurodollar Rate throughout the
applicable Interest Period designated by Borrower.
     
     4.3. Increments.
The initial applicable Prime Increment and Eurodollar Increment
shall be determined on the Effective Date in accordance with the
table below based on the ratio of (i) the Total Funded Indebtedness
of Borrower to (ii) the EBITDA of Borrower for the twelve month
period ended June 30, 1998.  Thereafter, the applicable Prime
Increment and Eurodollar Increment shall be determined quarterly,
beginning with Borrower's fiscal quarter ended September 30, 1998
in accordance with the table below, based on the ratio of
Borrower's Total Funded Indebtedness to Borrower's EBITDA, as
reflected in the consolidated Financial Statements of Borrower for
the fiscal quarter most recently ended, for the twelve month period
then ended:

    Ratio of Total Funded         Prime       Eurodollar
    Indebtedness to             Increment     Increment
    EBITDA                         (%)           (%)

  Greater than or                   0%         +1.75%
  equal to 1.75 to 1.00

  Greater than or                   0%         +1.50%
  equal to 1.50 to
  1.00 and less than
  1.75 to 1.00

  Less than 1.50 to 1.00            0%         +1.25%

Any change in the Prime Increment and Eurodollar Increment shall
become applicable on the fifth Business Day following the day when
Borrower delivers its Financial Statements for the fiscal quarter
most recently ended to Lender as required in Section 14.14.2.  The
foregoing notwithstanding, any change in the Eurodollar Increment
shall not become applicable to any Eurodollar Loan until and unless
it is renewed as a Eurodollar Loan.

     4.4. Conversion of Loans.
Borrower may (i) at any time convert some or all of a Prime Rate
Loan to a Eurodollar Loan, or (ii) at the end of any Interest
Period of a Eurodollar Loan, continue the Loan as a Eurodollar Loan
for an additional Interest Period or convert some or all of such
Eurodollar Loan to a Prime Rate Loan.  To cause any conversion or
continuation, Borrower shall give Lender, prior to 11:00 a.m. St.
Louis time at least two Business Days prior to the date the
conversion or continuation is to be effective, a written request
(which may be mailed, personally delivered or telecopied as
provided in Section 22.1) or an oral request (which must be
confirmed by facsimile on such date) (a) specifying whether a
conversion or continuation is requested, (b) in the case of a
conversion, specifying the amount to be converted and whether it is
to be a Eurodollar Loan or a Prime Rate Loan upon the conversion,
and (c) in the case of any conversion to or continuation of a
Eurodollar Loan, specifying the Interest Period therefor.  If such
notice is not given by 11:00 a.m. St. Louis time on the second
Business Day preceding the last day of the Interest Period of a
Eurodollar Loan, then Borrower shall be deemed to have timely given
a notice to Lender requesting to convert all of such Eurodollar
Loan to a Prime Rate Loan.  In the case of a Eurodollar Loan, any
conversion or continuation shall become effective only on the day
following the last day of the current Interest Period.

     4.5. Time of Accrual.
Interest shall accrue on all principal amounts outstanding from the
date when first outstanding to the date when no longer outstanding.
Amounts shall be deemed outstanding until payments are applied
thereto as provided herein.

     4.6. Computation.
Interest shall be computed for the actual days elapsed over a year
deemed to consist of 360 days.  Interest rates that are based on
the Prime Rate shall change simultaneously with any change in the
Prime Rate and shall be effective for the entire day on which such
change becomes effective.  The Prime Rate will be determined by
Lender before the initial Advance on the Effective Date and on each
Business Day thereafter when the Prime Rate changes.

     4.7. Rate After Maturity.
Borrower shall pay interest on the Loans after their Maturity, and
(at the option of Lender on the Loans and on the other Loan
Obligations) upon the occurrence and during the continuance of an
Event of Default, at a rate per annum of three percent (3%) plus
the interest rate otherwise in effect hereunder.
     
5.   Fees.
     
     5.1. Commitment Fee.
Borrower shall pay to Lender a "Commitment Fee" calculated by
applying the daily equivalent of the applicable per annum
"Commitment Fee Percentage" from the table below (based on the
ratio of Borrower's Total Funded Indebtedness to Borrower's EBITDA,
as reflected in the consolidated Financial Statements of Borrower
for the fiscal quarter most recently ended, for the twelve month
period then ended) to the Unused Revolving Commitment on each day
during the period from the Effective Date to the Maturity Date.
The "Unused Revolving Commitment" on any day shall be the amount of
the Revolving Loan Commitment minus the sum of the Aggregate
Revolving Loan and the Letter of Credit Exposure.  The Commitment
Fee shall be payable quarterly in arrears, commencing on the first
day of the first calendar quarter beginning after the Effective
Date and continuing on the first day of each calendar quarter
thereafter and on the Maturity Date.  Any change in the Commitment
Fee Percentage shall become applicable on the fifth Business Day
following the day when Borrower delivers its Financial Statements
for the fiscal quarter most recently ended to Lender as required in
Section 14.14.2.

    Ratio of Total Funded                Commitment fee
    Indebtedness to EBITDA                 Percentage
Greater than or equal to 1.75 to 1.00         .375%

Greater than or equal to 1.50                 .250%
to 1.00 and less than 1.75 to 1.00

Less than 1.50 to 1.00                        .125%
     
     5.2. Letter of Credit Fees.
Borrower shall pay to Lender a "Letter of Credit Fee" for each
Letter of Credit issued by Lender.  The Letter of Credit Fee for
each standby Letter of Credit shall be calculated by applying the
daily equivalent of the per annum Eurodollar Increment in effect on
the date of issuance of such Letter of Credit to the undrawn amount
available under such Letter of Credit as of each day commencing
when such Letter of Credit is issued by Lender.  The Letter of
Credit Fee for each documentary Letter of Credit shall be
calculated by applying the daily equivalent of the per annum
Commitment Fee Percentage in effect on the date of issuance of such
Letter of Credit to the undrawn amount available under such Letter
of Credit as of each day commencing when such Letter of Credit is
issued by Lender.  Borrower shall also pay to Lender a "Fronting
Fee" equal to .125% of the undrawn amount available under each
Letter of Credit issued by Lender as of its issuance date, and
Lender's other customary, nominal fees for issuance, amendment, or
renewal of a Letter of Credit and, as Lender and Borrower may agree
with respect to each Letter of Credit, for each negotiation of a
draft drawn under such Letter of Credit.  The Letter of Credit Fee
due for any Letter of Credit shall be payable quarterly in arrears
beginning on the first day of the first calendar quarter after the
date such Letter of Credit is issued and continuing on the first
day of each calendar quarter thereafter while such Letter of Credit
is outstanding.  The Fronting Fee due for any Letter of credit
shall be payable in advance, commencing on the issuance date of
such Letter of Credit.  Lender's customary fees for processing
draws on Letters of Credit and the like shall be payable in
accordance with Lender's practice at the time.
     
     5.3. Calculation of Fees.
All of the foregoing fees and all other fees payable to Lender that
are based on an annual percentage shall be calculated on the basis
of a year deemed to consist of 360 days and for the actual number
of days elapsed, and in accordance with Section 2.7.

6.   Payments.

     6.1. Scheduled Payments on Revolving Loan.

          6.1.1. Interest.
     Borrower  shall pay interest accrued on each Prime  Rate  Loan
     included  in the Revolving Loan quarterly in arrears beginning
     on  the first day of the first full calendar quarter following
     the  Effective Date and continuing on the first  day  of  each
     calendar  quarter  thereafter,  and  on  the  Revolving   Loan
     Maturity  Date.  Borrower shall pay interest accrued  on  each
     Eurodollar Loan included in the Revolving Loan at the  end  of
     its  Interest Period.  Borrower shall pay interest accrued  on
     each Revolving Loan after the Revolving Loan Maturity Date  on
     demand.

          6.1.2. Principal.
     Borrower  shall repay the entire amount of the Revolving  Loan
     on the Revolving Loan Maturity Date.
     
     6.2. Reimbursement Obligations.
Borrower hereby unconditionally agrees to immediately pay to Lender
on demand at the Lending Office all amounts required to pay all
drafts drawn under all Letters of Credit issued for the account of
Borrower and all reasonable expenses incurred by Lender in
connection with such Letters of Credit and, in any event and
without demand, to remit to Lender (which may be through obtaining
Advances if permitted under Section 3.1.2) sufficient funds to pay
all Obligations arising under any Letter of Credit issued for the
account of Borrower.  Borrower agrees to comply with all provisions
of any Letter of Credit application and reimbursement agreement,
and each application and reimbursement agreement shall be deemed to
be a "Loan Document" hereunder.
     
     6.3. Prepayments.

          6.3.1. Mandatory Prepayments When Over-Advances Exist.
     If at any time the Revolving Loan exceeds the Maximum
     Available Amount, whether as a result of optional Revolving
     Loan Advances by Lender as contemplated by Section 3.1.2,
     reductions in the Revolving Loan Commitment, or otherwise,
     Borrower shall immediately make a payment in the amount of
     such excess to Lender and the failure to make any such payment
     shall be an Event of Default.  Each such prepayment will be
     applied by Lender first to reduce the Prime Rate Loans that
     are included in the Revolving Loan until they are reduced to
     zero, and then to reduce the Eurodollar Loans that are
     included in the Revolving Loan.

     6.4. Manner of Payments and Timing of Application of Payments.

          6.4.1. Payment Requirement.
     Borrower  shall  make each payment on the Loan Obligations  to
     Lender  for  the account of Lender as required  hereunder  and
     under  the other Loan Documents at the Lending Office  on  the
     date  when  due,  without deduction, set-off or  counterclaim.
     All payments on the Loan Obligations shall be by wire transfer
     or direct debit to accounts maintained by Borrower at Lender.

     6.5. Application of Payments and Proceeds.
All payments received by Lender in immediately available funds at
or before 1:00 p.m. (St. Louis time) on a Business Day will be
applied to the relevant Loan Obligation on the same day.  Such
payments received on a day that is not a Business Day or after 1:00
p.m. on a Business Day will be applied to the relevant Loan
Obligation on the next Business Day.  Except as expressly provided
otherwise herein, Lender may apply, and reverse and reapply,
payments and proceeds of the Collateral to the Loan Obligations in
such order and manner as Lender determines in its absolute
discretion absent specific instructions by Borrower.  Borrower
hereby irrevocably waives the right to direct the application of
payments and proceeds of Collateral so long as there is any
Existing Default.  All payments and prepayments shall be deemed
made on Prime Rate Loans that are included in the Revolving Loan,
and then to the Eurodollar Loans included in the Revolving Loan;
provided, however, that payments received on the last day of any
Interest Period shall first be applied to the Eurodollar Loans with
an Interest Period ending on such date until such Loans are paid in
full, and then to the Prime Rate Loans included in the Revolving
Loan.

          6.5.1. Interest Calculation.
     Section 6.5 notwithstanding, for purposes of interest
     calculation only (i) a payment in cash, by wire transfer, or
     by ACH transfer, received at or before 1:00 p.m. (St. Louis
     time) on a Business Day shall be deemed to have been applied
     to the relevant Loan Obligation on the Business Day when it is
     received, and (ii) a payment in cash, by wire transfer or by
     ACH transfer, received on a day that is not a Business Day or
     after 1:00 p.m. (St. Louis time) on a Business Day shall be
     deemed to have been applied to the relevant Loan Obligation on
     the next Business Day.

     6.6. Voluntary Prepayments.
Borrower shall not be entitled to prepay any Eurodollar Loan
(except at the end of the applicable Interest Period).  Borrower
may wholly prepay any Prime Rate Loan that is included in the
Revolving Loan at any time and may make a partial prepayment
thereon from time to time, without penalty or premium.

     6.7. Returned Instruments.
If a payment is made by check, draft or other instrument and the
check, draft or other instrument is returned unpaid, any
application of the payment to the Loan Obligations will be reversed
and will be treated as never having been made.

     6.8. Compelled Return of Payments or Proceeds.
If Lender is for any reason compelled to surrender any payment or
any proceeds of Collateral because such payment or the application
of such proceeds is for any reason invalidated, declared
fraudulent, set aside, or determined to be void or voidable as a
preference, an impermissible setoff, or a diversion of trust funds,
then this Agreement and the Loan Obligations to which such payment
or proceeds was applied or intended to be applied shall be revived
as if such application was never made; and Borrower shall be liable
to pay to Lender, and shall indemnify Lender for and hold Lender
harmless from any loss with respect to, the amount of such payment
or proceeds surrendered.  This Section shall be effective
notwithstanding any contrary action that Lender may take in
reliance upon its receipt of any such payment or proceeds.  Any
such contrary action so taken by Lender shall be without prejudice
to Lender's rights under this Agreement and shall be deemed to have
been conditioned upon the application of such payment or proceeds
having become final and indefeasible.  The provisions of this
Section shall survive termination of the Commitments, the
expiration of all Letters of Credit, and the payment and
satisfaction of all of the Loan Obligations.

     6.9. Due Dates Not on Business Days.
If any payment required hereunder becomes due on a date that is not
a Business Day, then such due date shall be deemed automatically
extended to the next Business Day.

7.   Procedure for Obtaining Advances and Letters of Credit.

     7.1. Initial Advances.
Lender will fund and make the initial Revolving Loan Advance on the
Effective Date if directed by Borrower in a written direction
delivered to Lender.  The manner of disbursement shall be subject
to Lender's approval.

     7.2. Revolving Loan Advances.

          7.2.1. Borrower Requests.
     Borrower may request a Revolving Loan Advance at any time, but
     not more often than once each Business Day, by submitting a
     request therefor to Lender as provided in Section 7.8.  Every
     request for a Revolving Loan Advance shall be irrevocable.  A
     request for an Advance received by Lender on a day that is not
     a Business Day or that is received by Lender after 11:00 a.m.
     (St. Louis time) on a Business Day shall be treated as having
     been received by Lender at 11:00 a.m. (St. Louis time) on the
     next Business Day.  All Advances shall be funded to Borrower's
     account at Lender.

          7.2.2. Lender's Right to Make Other Revolving Loan Advances.

               7.2.2.1.  Payment of Loan Obligations.
          Lender  shall  have  the  right to  make  Revolving  Loan
          Advances  at  any  time and from time to  time  to  cause
          timely  payment  of  any of the Loan Obligations  or  any
          other  amounts required to be paid by Borrower  hereunder
          or  under  any of the other Loan Documents.   Lender  may
          select  the  Advance  Date for any  such  Revolving  Loan
          Advance,  but  such Advance Date may only be  a  Business
          Day.   Lender will use reasonable efforts to give  notice
          to Borrower after any such Revolving Loan Advance is made
          (but  shall  have no liability for failing to  give  such
          notice).  Any such Revolving Loan Advance will be a Prime
          Rate Advance.

               7.2.2.2.  Payments to Other Creditors.
          If  Lender becomes obligated to reimburse or pay  to  any
          creditor of Borrower any amount in order to (i) obtain  a
          release  of such creditor's Security Interest in  any  of
          the  Collateral, or (ii) otherwise satisfy an  Obligation
          of   Borrower  to  such  creditor  to  the   extent   not
          indefeasibly  satisfied  by the  initial  Advances,  then
          Lender  shall  have  the  right to  make  Revolving  Loan
          Advances for that purpose.  Lender may select the Advance
          Date for any such Advance, but such Advance Date may only
          be a Business Day.  Lender will use reasonable efforts to
          give  notice  to  Borrower prior to such  Revolving  Loan
          Advance  being  made  (but shall have  no  liability  for
          failure  to  give such notice) and will  give  notice  to
          Borrower  after any such Revolving Loan Advance is  made.
          Any  such  Revolving Loan Advance will be  a  Prime  Rate
          Advance.

     7.3. Letters of Credit.
Borrower may request the issuance of a Letter of Credit by
submitting an issuance request to Lender that meets the
requirements of Section 7.9 and executing the reimbursement
agreement required under Section 11.1 no less than five Business
Days prior to the requested issue date for such Letter of Credit.

     7.4. Disbursement.
Provided that all conditions precedent herein to a requested
Advance have been satisfied, Lender will make the amount of such
requested Advance available to Borrower on the applicable Advance
Date in immediately available funds in Dollars at the Lending
Office.

     7.5. Restrictions on Advances.
No Prime Rate Advance will be made unless it is a whole multiple of
$100,000 and not less than $100,000.  No Eurodollar Advance will be
made unless it is a whole multiple of $250,000 and not less than
$250,000.  No more than one Revolving Loan Advance (which may
include a portion which is a Eurodollar Loan and a portion which is
a Prime Rate Loan) will be made on any one day pursuant to a
request for a Revolving Loan Advance although a second Revolving
Loan Advance on a given day may be made for a Prime Rate Loan
pursuant to a request for a Revolving Loan Advance that was made on
a different day than the other request.  Advances will only be made
for the purposes permitted in Section 14.1.

     7.6. Restriction on Number of Eurodollar Loans.
No more than six (6) Eurodollar Loans may be outstanding at any one
time.

     7.7. Each Advance Request Certification.
Each submittal of a request for an Advance by a Borrowing Officer
shall constitute a certification by Borrower that (i) there is no
Existing Default, (ii) all representations and warranties of
Borrower in this Agreement and the other Loan Documents are then
true, with such exceptions as have been disclosed to Lender in
writing by Borrower as addenda to the Disclosure Schedule which are
satisfactory to Lender, and will be true on the Advance Date or
issuance date, as applicable, as if then made with such exceptions
and except that with respect to the representations and warranties
made regarding Financial Statements or financial data, such
representations and warranties shall be deemed made with respect to
the most recent Financial Statements and other financial data
delivered by Borrower, and (iii) all conditions precedent hereunder
to the making of the requested Advance shall have been satisfied.

     7.8. Requirements for Every Advance Request.
Only a request (which shall be in writing and mailed, personally
delivered or telecopied as provided in Section 22.1; or if oral,
which shall be confirmed in writing via facsimile on the date of
such request) in the form of Exhibit 7.8 from a Borrowing Officer
to Lender that specifies the amount of the Advance to be made, the
Advance Date for the requested Advance, the portion of the Advance
which is requested to be a Eurodollar Advance, the portion of the
Advance which is requested to be a Prime Rate Advance, and the
Interest Period to be applicable to the Eurodollar Loan that will
result from a requested Eurodollar Advance, shall be treated as a
request for an Advance.  No Advance Date for any requested Advance
may be other than a Business Day.  A request for a Eurodollar
Advance must be given prior to 11:00 a.m., St. Louis time, at least
two Business Days prior to the Advance Date for such Eurodollar
Advance.  A request for a Prime Rate Advance must be given prior to
11:00 a.m., St. Louis time, on the Advance Date for such Prime Rate
Advance.

     7.9. Requirements for Every Request for Issuance of a Letter
of Credit.
Only a written request from a Borrowing Officer to Lender that
specifies the amount, the requested issue date and the beneficiary
of the requested Letter of Credit and other information necessary
for its issuance shall be treated as an issuance request for the
purposes hereof.

     7.10. Exoneration of Lender.
Lender shall not incur any liability to Borrower for treating a
request that meets the express requirements of Section 7.8 as a
request for an Advance or a request for issuance of a Letter of
Credit, as applicable, if Lender believes in good faith that the
Person making the request is a Borrowing Officer.  Lender shall not
incur any liability to Borrower for failing to treat any such
request as a request for an Advance or a request for issuance of a
Letter of Credit, as applicable, if Lender believes in good faith
that the Person making the request is not a Borrowing Officer.

     7.11. Suspension of Obligation to Make Eurodollar Advances.
If (i) on any date for determining the Eurodollar Rate for any
Interest Period, by reason of any changes arising after the
Execution Date affecting the London Interbank Market or Lender's
position in such market, adequate and fair means do not exist for
ascertaining the applicable interest rate on the basis provided for
in the definition herein of Eurodollar Rate, or (ii) the making of
any Advance which is to be a Eurodollar Advance or the continuance
by Lender of any Eurodollar Loan has become unlawful by compliance
by Lender in good faith with any Law or any pronouncement of a
Governmental Authority (whether or not having the force of law and
whether or not failure to comply therewith would be unlawful), then
Lender shall promptly give notice to Borrower of such
determination.  Until Lender notifies Borrower that the
circumstances giving rise to the suspension described herein no
longer exist, (a) the obligation of Lender to fund Eurodollar
Advances shall be suspended, (b) each outstanding Eurodollar Loan
shall be automatically converted into a Prime Rate Loan, on the
earlier of the last day of the Interest Period for such Eurodollar
Loan or the last date permitted by applicable Law, and (c) all
Revolving Loan Advances shall be Prime Rate Advances.
Notwithstanding anything to the contrary contained herein, if any
part of a Eurodollar Loan is converted to a Prime Rate Loan
pursuant to this Section 7.11, the per annum interest rate
applicable thereto from and after the effective date of such
conversion shall be the Prime Rate (but otherwise calculated as
provided in Section 4).

8.   Security and Guaranties.
To secure the payment and performance of the Loan Obligations,
Borrower shall on the Execution Date execute and deliver, or cause
to be executed and delivered, to Lender the following documents
from time to time, each satisfactory to Lender:

Indebtedness and the reduction of the Revolving Loan Commitment to
an amount not greater than $6,000,000 so long as there is no
Existing Default at such time.  If Borrower or any other Covered
Person acquires or leases any real property in the United States
after the Execution Date (other than any lease which is not a
ground lease), such Covered Person shall notify Lender thereof and
shall deliver to Lender a deed of trust or mortgage, or leasehold
deed of trust or mortgage, as appropriate, on each parcel of such
real property promptly upon request by Lender, and if any other
tenants have possession of a material portion of such real
property, Borrower or such Covered Person shall deliver or cause to
be delivered to Lender a nondisturbance, attornment, and
subordination agreement executed by such tenant and acceptable to

Lender may, either before or after an Event of Default, exchange,

any real or personal property for any of the Collateral, without
affecting the Loan Obligations or Lender's right to take any other
action with respect to any other Collateral.  Upon indefeasible

of the Commitments, Lender shall, upon the request of Borrower, and
at Borrower's sole cost and expense, provide documentation

under the Laws of the state or nation of its organization, is duly
qualified to do business and is in good standing in every state
where the nature or extent of its business or properties require it

on its business as now being conducted.

     12.2. Authorization.
Each Covered Person is duly authorized to execute and perform every
Loan Document to which such Covered Person is a party, and Borrower

the Security Interests in the Collateral), and no consent of any
other Person, is required in connection with each Covered Person's
execution, delivery or performance of this Agreement and the other

executed on behalf of such Covered Person by a Person duly
authorized to do so.

     12.4. Enforceability of Obligations.

constitutes the legal, valid and binding obligation of such Covered
Person, enforceable against such Covered Person in accordance with
its terms, except to the extent that the enforceability thereof
against such Covered Person may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar Laws affecting
creditors' rights generally or by equitable principles of general
application.

     12.5. Burdensome Obligations.
No Covered Person is a party to or bound by any Contract or is

Event of Default either immediately or upon the elapsing of time.

     12.6. Legal Restraints.
The execution and performance of any Loan Document by a Covered
Person will not violate or constitute a default under the Charter
Documents of such Covered Person, any Material Agreement of such
Covered Person (except to the extent that the grant of a Security
Interest in such Material Agreement to Lender would cause a breach
by such Covered Person under such Material Agreement), or any
Material Law, and will not, except as expressly contemplated or
permitted in this Agreement, result in any Security Interest being
imposed on any of such Covered Person's property.

     12.7. Labor Disputes.

strike, work stoppage, unfair labor practice claim or other labor

     of any Covered Person are the subject of investigation by any
     Governmental Authority regarding the improper transportation,
     storage, disposal, generation or release into the environment
     of any Hazardous Material, the results of which have or are
     reasonably likely to have a Material Adverse Effect on such
     Covered Person, or reduce materially the value of Covered
     Person's property.

          12.10.2. Hazardous Materials on Real Property.
     No Covered Person, nor to Borrower's knowledge, any other
     Person, has at any time transported, stored, disposed of,
     generated or released any Hazardous Material on the surface,
     below the surface, or within the boundaries of the real

          systems will be able to perform date-sensitive functions
          prior to and after December 31, 1999); and Borrower

          Borrower reasonably believes any suppliers and vendors
          that are material to the operations of any Covered Person

          have a Material Adverse Effect on any Covered Person.

contained herein, in any other Loan Document, or in any certificate
delivered by any Covered Person pursuant hereto or thereto, as the
same may be updated, modified or amended from time to time upon a
Covered Person's written request to Lender of such update,
modification or amendment and upon Lender's written approval of the
same shall survive execution of each of the Loan Documents and the
making of every Advance, and may be relied upon by Lender as being
true and correct as of the date when made or deemed made or
reaffirmed until all of the Loan Obligations are fully and

well as for general corporate and working capital purposes.

     14.2. Corporate Existence.
Each Covered Person shall maintain its existence in good standing
and shall maintain in good standing its right to transact business
in those states or countries in which it is now or hereafter doing
business, except where the failure to so qualify will not have and
will not be reasonably likely to have a Material Adverse Effect.
Each Covered Person shall obtain and maintain all Material Licenses
for such Covered Person.

     14.3. Maintenance of Property and Leases.
Each Covered Person shall maintain in good condition and working
order, and repair (ordinary wear and tear excepted) and replace as
required, all buildings, equipment, machinery, fixtures and other
real and personal property whose useful economic life to such
Covered Person has not elapsed and which is reasonably necessary
for the ordinary conduct of the business of such Covered Person.
Each Covered Person shall maintain in good standing and free of
material defaults all of its leases of buildings, equipment,
machinery, fixtures and other real and personal property whose
useful economic life to such Covered Person has not elapsed and
which is necessary for the ordinary conduct of the business of such
Covered Person.

     14.4. Inventory.
Each Covered Person shall keep its Inventory in good and
merchantable condition at its own expense and shall hold such
Inventory for sale or lease, or to be furnished in connection with
the rendition of services, in the ordinary course of such Covered

     14.5. Insurance.
Each Covered Person shall at all times keep insured or cause to be
kept insured, in insurance companies having a rating of at least

character usually insured by others carrying on businesses similar

and covering such risks as such properties are usually insured.
Each Covered Person shall carry business interruption insurance at
such levels as are acceptable to Lender.  Each Covered Person shall
at all times carry insurance, in insurance companies having a
rating of at least "A" by Best's Rating Service, against liability
on account of damage to persons or property (including product
liability insurance and insurance required under all Laws
pertaining to workers' compensation) and covering all other
liabilities common to such Covered Person's business, in such
manner and to such extent as such coverage is usually carried by
others conducting businesses similar to that of such Covered
Person. All policies of liability insurance maintained hereunder
shall name Lender as an additional insured; all fire and casualty
policies of insurance maintained by Borrower hereunder shall
reflect Lender's interest therein as mortgagee under a standard New
York or Union mortgagee clause.  If an Event of Default has
occurred, Lender is authorized, but not obligated, as the attorney-
in-fact for Borrower, (i) to adjust and compromise proceeds payable
under such policies of insurance, (ii) to collect, receive and give
receipts for such proceeds in the name of Borrower and Lender, and
(iii) to endorse Borrower's name upon any instrument in payment
thereof.  Such power granted to Lender shall be deemed coupled with
an interest and shall be irrevocable.  All policies of insurance
maintained hereunder shall contain a clause providing that such
policies may not be canceled, reduced in coverage or otherwise
modified without 30 days prior written notice to Lender.  Borrower
shall upon request of Lender at any time furnish to Lender updated
evidence of insurance (in the form required as a condition to
Lender's lending hereunder) for such insurance.

every part thereof, or upon the income or profits therefrom and all
claims of materialmen, mechanics, carriers, warehousemen, landlords
and other like Persons for labor, materials, supplies, storage or
other items or services which if unpaid might be or become a
Security Interest or charge upon any of the Collateral or its other
property; provided, however, that a Covered Person may diligently
contest in good faith by appropriate proceedings the validity of
any such taxes, rates, levies, or assessments, provided such
Covered Person has established adequate reserves therefor in
conformity with GAAP on the books of such Covered Person, and no
Security Interest, other than a Permitted Security Interest,
results from such non-payment.

     14.7. Compliance With Laws.
Each Covered Person shall comply with all Material Laws.

     14.8. Discovery and Clean-Up of Hazardous Material.
Upon any Responsible Officer of any Covered Person receiving notice
or becoming aware of any violation of Environmental Laws or any
similar notice described in Section 14.10.2, or upon any Covered
Person otherwise discovering Hazardous Material on any property
owned or leased by such Borrower which is in violation of, or which
would result in liability under, any Environmental Law, Borrower
shall: (i) promptly take such acts as may be necessary to prevent
danger or harm to the property or any person therein as a result of
such Hazardous Material; and (ii) take all necessary steps to
initiate and expeditiously complete all removal, remedial,
response, corrective and other action to eliminate any such
environmental problems, and keep Lender informed of such actions
and the results thereof.

     14.9. Termination of Pension Benefit Plan.
No Covered Person or ERISA Affiliate of any Covered Person shall
terminate or amend any Pension Benefit Plan maintained by such

to have a Material Adverse Effect, or any increase in current
liability for the plan year for which such Covered Person or such
ERISA Affiliate is required to provide security to such Pension
Benefit Plan under the Code, which could reasonably be likely to
have a Material Adverse Effect.

     14.10. Notice to Lender of Material Events.
Borrower shall, promptly upon any Responsible Officer of Borrower

Default; (iii) the commencement of any Material Proceeding; and

     reasonably be expected to result in a Material Adverse Effect.

          14.10.4.

Person shall maintain materially accurate and reasonably detailed
records of proceeds of the Loans and substantial transfers of
proceeds of the Loans (i) received by it from the Lender,
(ii) transferred from it to any other Covered Person, and
(iii) received by it from another Covered Person.  Borrower
acknowledges that (i) its ability to obtain the Loans hereunder is
made possible by the fact  that each of the Covered Persons is
guarantying the Loan Obligations, (ii) the business operations of
each Covered Person complement one another, and such entities have
a common business purpose, and (iii) the proceeds of Advances
hereunder will benefit each Covered Person, severally and jointly,
regardless of which Covered Person receives part or all of any
Advance.

     the consolidated financial statements, a statement comparing
     the current statements delivered pursuant to this Section with
     the statements for the equivalent months and equivalent
     elapsed periods during the prior fiscal year of Borrower.

     Such cancellation may be, in either case, without presentment,
     demand or notice of any kind, which Borrower expressly waives.

          17.2.2. Acceleration.
     Upon an Event of Default described in Section 17.1.10, all of
     the outstanding Loan Obligations shall automatically become
     immediately due and payable.  During any other Existing

     Obligations immediately due and payable.  Such acceleration
     may be, in either case, without presentment, demand or notice
     of any kind, which Borrower expressly waives.

          17.2.3. Right of Set-off.
     During any Existing Default, Lender is hereby authorized,
     without notice to Borrower (any such notice being expressly
     waived by Borrower; Lender will use reasonable efforts to
     provide subsequent notice to Borrower but Lender shall not be
     liable for any failure to give such notice), to set off and
     apply against the Loan Obligations any and all deposits
     (general or special, time or demand, provisional or final) or
     other assets at any time held or at Lender, or any other
     Indebtedness at any time owing by Lender to or for the credit
     or the account of Borrower, irrespective of whether or not
     Lender shall have made any demand under this Agreement or the
     Notes and although such Loan Obligations may be unmatured.
     The rights of Lender under this Section are in addition to
     other rights and remedies (including, without limitation,
     other rights of set-off) which Lender may otherwise have.

          17.2.4. Notice to Account Debtors.
     Upon the occurrence and during the continuance of any Event of
     Default and at any time and from time to time thereafter,
     Lender may, without prior notice to Borrower (Lender will use
     reasonable efforts to provide subsequent notice to Borrower
     but Lender shall not be liable for any failure to give such
     notice), notify any or all Account Debtors that the Accounts
     have been assigned to Lender and that Lender has a Security
     Interest therein, and Lender may direct, or Borrower, at
     Lender's request, shall direct, any or all Account Debtors to
     make all payments upon the Accounts directly to Lender for the
     benefit of Lender.

          17.2.5. Entry Upon Premises and Access to Information.
     During an Existing Default and acceleration of the Loan
     Obligations as provided herein, and at any time thereafter:
     Lender may (i) enter upon the premises leased or owned by
     Borrower where Collateral is located (or is believed to be
     located) without any obligation to pay rent to Borrower, or
     any other place or places where Collateral is believed to be
     located, (ii) render Collateral usable or saleable,
     (iii) remove Collateral to the premises of Lender or any agent
     of Lender for such time as Lender may desire in order
     effectively to collect or liquidate Collateral; (iv) take
     possession of, and make copies and abstracts of Borrower's
     original books and records, obtain access to Borrower's data
     processing equipment, computer hardware and software relating
     to any of the Collateral and use all of the foregoing and the
     information contained therein in any manner Lender deems
     appropriate in connection with the exercise of Lender's
     rights; and (v) notify postal authorities to change the
     address for delivery of Borrower's mail to an address
     designated by Lender and to receive, open and process all mail
     addressed to Borrower (so long as Lender provides copies of
     such mail to Borrower; it being agreed that Lender shall not
     be liable for any failure to provide such copies).

          17.2.6. Borrower's Obligations.
     During an Existing Default, Borrower shall, if Lender so
     requests, assemble all the movable tangible Collateral and
     make it available to Lender at a place or places to be
     designated by Lender in its reasonable discretion.

          17.2.7. Secured Party Rights.
     During an Existing Default and acceleration of the Loan
     Obligations as provided herein, and at any time and from time
     to time thereafter:
                    
               17.2.7.1. Lender may exercise any or all of its
          rights under the Security Documents as a secured party
          under the UCC and any other applicable Law; and

               17.2.7.2.
          Lender may sell or otherwise dispose of any or all of the
          Collateral at public or private sale in a commercially
          reasonable manner, which sale Lender may postpone from
          time to time by announcement at the time and place of
          sale stated in the notice of sale or by announcement at
          any adjourned sale without being required to give a new
          notice of sale, all as Lender deems advisable, for cash
          or credit.  Lender may become the purchaser at any such
          sale if permissible under applicable Law, and Lender may,
          in lieu of actual payment of the purchase price, offset
          the amount thereof against Borrower's obligations owing
          to Lender, and Borrower agrees that Lender has no
          obligation to preserve rights to Collateral against prior
          parties or to marshal any Collateral for the benefit of
          any Person.

     In connection with the advertising for sale, selling, further
     manufacture, or otherwise realizing upon any of the Collateral
     securing the obligations of Borrower to Lender, Lender may use
     and is hereby granted a license to use, without charge or
     liability to Lender therefor, any of Borrower's labels, trade
     names, trademarks, trade secrets, service marks, patents,
     patent applications, licenses, certificates of authority,
     advertising materials, or any of Borrower's other properties
     or interests in properties of similar nature, to the extent
     that such use thereof is not prohibited by agreements under
     which Borrower has rights therein, and all of Borrower's
     rights under license, franchise and similar agreements shall
     inure to Lender's benefit.
     
          17.2.8. Miscellaneous.
     During an Existing Default and at any time thereafter, Lender
     may exercise any other rights and remedies available to Lender
     under the Loan Documents or otherwise available to Lender at
     law or in equity.

          17.2.9. Application of Funds.
     Any funds received by Lender with respect to the Loan
     Obligations after maturity or any acceleration, including
     proceeds of any of any Covered Person's property, shall be
     applied as follows:  (i) first, to reimburse Lender for any
     amounts due to Lender under Section 21.5; (ii) second, to
     reimburse to Lender all unreimbursed costs and expenses paid
     or incurred by Lender that are payable or reimbursable by
     Borrower hereunder; (iii) third, to the payment of accrued and
     unpaid fees due hereunder and all other amounts due hereunder
     (other than the Loans and interest accrued thereon);
     (iv) fourth, to the payment of interest accrued on the Loans
     to Lender; (v) fifth, to the payment of the Loans, in such
     order as Lender determines in its absolute discretion; and
     (vi) sixth, to the payment of the other Loan Obligations.  Any
     remaining amounts shall be paid to Borrower or such other
     Persons as shall be legally entitled thereto.  Borrower hereby
     waives the right to direct the application of payments and
     proceeds of the Collateral.
     
     17.3. Limitation of Liability; Waiver.
Lender shall not be liable to Borrower or any other Covered Person
as a result of any commercially reasonable possession,
repossession, collection or sale by Lender of Collateral; and
Borrower hereby waives all rights of redemption from any such sale
and the benefit of all valuation, appraisal and exemption Laws.  If
Lender seeks to take possession of any of the Collateral by
replevin or other court process after an Event of Default, Borrower
hereby irrevocably waives (i) the posting of any bonds, surety and
security relating thereto required by any statute, court rule or
otherwise as an incident to such possession, (ii) any demand for
possession of the Collateral prior to the commencement of any suit
or action to recover possession thereof, (iii) any requirement that
Lender retain possession and not dispose of any Collateral until
after trial or final judgment, and (iv) to the extent permitted by
applicable Law, all rights to notice and hearing prior to the
exercise by Lender of its right to repossess the Collateral without
judicial process or to replevy, attach or levy upon the Collateral
without notice or hearing.  No Lender shall have any obligation to
preserve rights to the Collateral or to marshall any Collateral for
the benefit of any Person.
     
     17.4. Notice.
Any notice of intended action required to be given by Lender
(including notice of a public or private sale of Collateral), if
given as provided in Section 22.1 at least 10 days prior to such
proposed action, shall be effective and constitute reasonable and
fair notice to Borrower.
     
18.  Changes in Circumstances.

     18.1. Compensation for Increased Costs and Reduced Returns;
Capital Adequacy.


          18.1.1. Increased Costs or Reduced Returns to Lender.
     If,  after the date hereof, the adoption of any applicable Law
     or  any  change  in any applicable Law or any  change  in  the
     interpretation  or administration thereof by any  Governmental
     Authority  charged  with the interpretation or  administration
     thereof, or compliance by Lender (or the Lending Office)  with
     any  request or directive (whether or not having the force  of
     law) of any such Governmental Authority:

          (i)   subjects Lender (or the Lending Office) to any  Tax
          with respect to any Eurodollar Loan or its obligation  to
          make  any  Advance  that will be a  Eurodollar  Loan,  or
          change  the  basis of taxation of any amounts payable  to
          Lender  (or  the Lending Office) under this Agreement  in
          respect  of any Eurodollar Loan (other than Taxes imposed
          on  the  overall net income of Lender by the jurisdiction
          in  which Lender has its principal office or the  Lending
          Office);

          (ii)  imposes, modifies, or deems applicable any reserve,
          special  deposit, assessment, compulsory loan or  similar
          requirement (other than the Reserve Requirement) relating
          to  any  extensions of credit or other assets of, or  any
          deposits  with  or other liabilities or  Commitments  of,
          Lender (or the Lending Office), including the Commitments
          of Lender hereunder; or

          (iii)      imposes on Lender (or the Lending Office),  or
          the   London   interbank  market,  any  other   condition
          affecting this Agreement, the Commitments or any  of  the
          Loan Obligations;

     and the result of any of the foregoing is to increase the cost
     to Lender (or the Lending Office) of making, converting into,
     continuing, or maintaining any Revolving Loan or to reduce any
     sum received or receivable by Lender (or the Lending Office)
     under this Agreement or any of the other Loan Documents with
     respect to any Revolving Loan, then Borrower shall pay to
     Lender on demand such amount or amounts as will compensate
     Lender for such increased cost or reduction.  If Lender
     requests compensation by Borrower under this Section Borrower
     may, by notice to Lender, suspend the obligation of Lender to
     make or continue Revolving Loans of the type with respect to
     which such compensation is requested, or to convert Revolving
     Loans of any other type into Revolving Loans of such type,
     until the event or condition giving rise to such request
     ceases to be in effect (in which case the provisions of
     Section 18.5 shall be applicable); provided, however, that
     such suspension shall not affect the right of Lender to
     receive the compensation so requested for any continuing
     Revolving Loan outstanding or any subsequent Revolving Loan.
     Notwithstanding the foregoing provisions of this Section
     18.1.1 during any Interest Period, Borrower shall not be
     liable to Lender for any additional costs imposed on Lender in
     connection with any Eurodollar Loan which arise as a result of
     a cost increase described above during such Interest Period
     (but will be liable for such costs during any subsequent
     Interest Periods).

          18.1.2. Capital Adequacy.
     If  at  any time after the date hereof Lender determines  that
     the  adoption of any applicable Law regarding capital adequacy
     or   any   change   therein  or  in  the   interpretation   or
     administration thereof by any governmental authority,  charged
     with  the  interpretation or administration  thereof,  or  any
     request  or  directive regarding capital adequacy (whether  or
     not  having  the  force  of  law)  of  any  such  Governmental
     Authority, has or would have the effect of reducing  the  rate
     of  return  on  the  capital  of  Lender  or  any  corporation
     controlling  Lender  as a consequence of Lender's  obligations
     hereunder  to  a  level  below  that  which  Lender  or   such
     corporation could have achieved but for such adoption, change,
     request,  or directive (taking into consideration its policies
     with respect to capital adequacy), then from time to time upon
     demand Borrower shall pay to Lender such additional amount  or
     amounts as will compensate Lender for such reduction.

          18.1.3. Notice to Borrower.
     Lender shall promptly notify Borrower of any event of which it
     has knowledge, occurring after the date hereof, which will
     entitle Lender to compensation pursuant to this Section 18.1
     and will designate a different Lending Office if such
     designation will avoid the need for, or reduce the amount of,
     such compensation and will not, in the judgment of Lender, be
     otherwise disadvantageous to it.  If Lender claims
     compensation under this Section, Lender will furnish to
     Borrower a statement stating the additional amount or amounts
     to be paid to it hereunder, which shall be conclusive in the
     absence of manifest error.  In determining such amount, Lender
     may use any reasonable averaging and attribution methods.

     18.2. Limitations on Eurodollar Loans.
If on or prior to the first day of any Interest Period for any
Eurodollar Loan:

          18.2.1. Market Failure.
     Lender determines (which determination shall be conclusive)
     that by reason of circumstances affecting the relevant market,
     adequate and reasonable means do not exist for ascertaining
     the Eurodollar Rate for such Interest Period; or

          18.2.2. Inadequate Reflection of Cost.
     Lender determines (which determination shall be conclusive)
     that the Eurodollar Rate will not adequately and fairly
     reflect the cost to Lender of funding Eurodollar Loans for
     such Interest Period;

then Lender will give Borrower prompt notice thereof, and while
such condition remains in effect, Lender will have no obligation to
make additional Advances that will be Eurodollar Loans, to continue
Eurodollar Loans, or to convert Prime Rate Loans into Eurodollar
Loans.

     18.3. Illegality.
Notwithstanding any other provision of this Agreement, in the event
that it becomes unlawful for Lender or the Lending Office to make
Advances that will be Eurodollar Loans or maintain Eurodollar Loans
hereunder, then Lender shall promptly notify Borrower thereof and
Lender's obligation to do so or to convert Prime Rate Loans into
Eurodollar Loans shall be suspended until such time as Lender may
again do so, and Lender's outstanding Eurodollar Loans shall be
converted into Prime Rate Loans in accordance with Section 18.5.

     18.4. Compensation.
Upon the request of Lender, Borrower shall pay to Lender such
amount or amounts as will be sufficient (in the reasonable
determination of Lender) to compensate it for any loss, cost, or
expense (including loss of anticipated profits) incurred by it as a
result of:

          18.4.1. Early Payment.
     any  payment,  prepayment, or conversion of a Eurodollar  Loan
     for   any   reason   (including,   without   limitation,   the
     acceleration  of  the  Revolving Loan pursuant  to  the  terms
     hereof)  on  a  date other than the last day of  the  Interest
     Period for such Eurodollar Loan; or

          18.4.2. Failure to Take Advances.
     any failure by Borrower for any reason (other than pursuant to
     Section 18.2 or 18.3) to take an Advance that is requested to
     be a Eurodollar Loan or to convert, continue, or prepay a
     Eurodollar Loan on the date therefor specified in the relevant
     request for an Advance or notice of prepayment, continuation,
     or conversion under this Agreement.

     If Lender claims compensation under this Section 18.4, Lender
shall furnish a certificate to Borrower that states the amount to
be paid to it hereunder and includes a description in reasonable
detail of the method used by Lender in calculating such amount.
Borrower shall have the burden of proving that the amount of any
such compensation calculated by Lender is not correct.  Any
compensation payable by Borrower to Lender under this Section shall
be payable without regard to whether Lender has funded any Advance
or Eurodollar Loan through the purchase of deposits in an amount or
of a maturity corresponding to the deposits used as a reference in
determining the Eurodollar Rate as provided herein.

     18.5. Treatment of Affected Revolving Loans.
If the obligation of Lender to make an Advance that will be a
Eurodollar Loan or to continue any Eurodollar Loan or to convert
any Prime Rate Loan into a Eurodollar Loan shall be suspended
pursuant to Section 18.2 or 18.3 each such Revolving Loan shall be
automatically and immediately converted into a Prime Rate Loan on
the last day of its Interest Period (or, in the case of a
conversion required by Section 18.3, on such earlier date as Lender
may specify to Borrower).  Unless and until Lender gives notice as
provided below that the circumstances specified in Section 18.2 or
18.3 that gave rise to such conversion no longer exist:

          18.5.1. Payments.
     To   the  extent  that  such  Revolving  Loans  have  been  so
     converted,  all  payments and prepayments  of  principal  that
     would  otherwise  be  applied to such  Revolving  Loans  shall
     continue to be made and applied as provided for herein; and

          18.5.2. Prime Rate.
     All Advances by Lender that would otherwise become Eurodollar
     Loans and all Revolving Loans that would otherwise be
     continued by Lender as Eurodollar Loans shall become or be
     continued instead as Prime Rate Loans, and all Revolving Loans
     that would otherwise be converted into Eurodollar Loans shall
     be converted instead into (or shall remain as) Prime Rate
     Loans.

     Lender shall give prompt notice to Borrower if and when the
circumstances specified in Section 18.2 or 18.3 that gave rise to
the conversion of Revolving Loans pursuant to this Section 18.5 no
longer exist.

19.  Taxes.

     19.1. Gross-Up.
All payments by Borrower to or for the account of Lender hereunder
or under any other Loan Document shall be made free and clear of
and without deduction for all present or future Taxes, excluding
franchise Taxes and Taxes imposed on Lender's net income, by the
jurisdiction under the Laws of which Lender is organized or the
Lending Office is located or any political subdivision thereof.  If
Borrower is required by Law to deduct any Taxes from or in respect
of any sum payable under this Agreement or any other Loan Document
to Lender, (i) the sum payable shall be increased as necessary so
that after making all required deductions (including deductions
applicable to additional sums payable under this Section) Lender
receives an amount equal to the sum it would have received had no
such deductions been made, (ii) Borrower shall make such
deductions, (iii) Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance
with applicable Law, and (iv) Borrower shall furnish to Lender, at
its address referred to herein, the original or a certified copy of
a receipt evidencing payment thereof.  In addition, Borrower agrees
to pay any and all present or future Impositions.  Impositions
include stamp or documentary taxes and any other excise or property
taxes or charges or similar levies which arise from the Loan
Obligations, any payment made under this Agreement or any other
Loan Document or from the execution or delivery of, or otherwise
with respect to, the Loan Obligations, this Agreement or any other
Loan Document.  Borrower agrees to indemnify Lender for the full
amount of all Impositions and Taxes, excluding franchise Taxes and
Taxes imposed on Lender's net income, (including any such Taxes or
Impositions imposed or asserted by any jurisdiction on amounts
payable under this Section) paid by Lender and any liability
(including penalties, interest and expenses) arising therefrom or
with respect thereto.  Within thirty days after the date of any
payment of Taxes, Borrower shall furnish Lender the original or a
certified copy of a receipt evidencing such payment.

     19.2. Lender's Undertaking.
If Borrower is required to pay additional amounts to or for the
account of Lender pursuant to Section 19.1, then Lender will use
reasonable efforts to change the jurisdiction of the Lending Office
so as to eliminate or reduce any such additional payment which may
thereafter accrue if such change, in the judgment of Lender, is not
otherwise disadvantageous to Lender.

20.  Usury Limitations.
Notwithstanding any provisions to the contrary in Section 4 or
elsewhere in any of the Loan Documents, Borrower shall not be
obligated to pay interest at a rate which exceeds the maximum rate
permitted by Law.  If, but for this Section 20, Borrower would be
deemed obligated to pay interest at a rate which exceeds the
maximum rate permitted by Law, or if any of the Loan Obligations is
paid or becomes payable before its originally scheduled Maturity
and as a result Borrower has paid or would be obligated to pay
interest at such an excessive rate, then (i) Borrower shall not be
obligated to pay interest to the extent it exceeds the interest
that would be payable at the maximum rate permitted by Law; (ii) if
the outstanding Loan Obligations have not been accelerated as
provided in Section 17.2.2, any such excess interest that has been
paid by Borrower shall be refunded; (iii) if the outstanding Loan
Obligations have been accelerated as provided in Section 17.2.2,
any such excess that has been paid by Borrower shall be applied to
the Loan Obligations as provided in Section 17.2.9; and (iv) the
effective rate of interest shall be deemed automatically reduced to
the maximum rate permitted by Law.

21.  General.

     21.1. Lender's Right to Cure.
So long as there is an Existing Default, after first giving notice
to Borrower, Lender may from time to time, in its absolute
discretion, for Borrower's account and at Borrower's expense, pay
or make a Revolving Loan Advance to pay any amount or do any act
required of Borrower hereunder.  So long as there is an Existing
Default, Lender may also from time to time, in its absolute
discretion, for Borrower's account and at Borrower's expense pay or
make a Revolving Loan Advance to pay any amount or do any act
reasonably requested by Lender to preserve, protect, maintain or
enforce the Loan Obligations, the Collateral or Lenders' Security
Interests therein and which Borrower fails to pay or do.  Such
payments and actions include payment of any judgment against
Borrower, insurance premium, taxes or assessments, warehouse
charge, finishing or processing charge, landlord's claim, and any
other claim. All payments made by Lender pursuant to this Section
and all out-of-pocket costs and expenses incurred by Lender in
connection with any action taken by Lender hereunder shall be a
part of the Loan Obligations, the repayment of which shall be
secured by the Collateral. Any payment made or other action taken
by Lender pursuant to this Section shall be without prejudice to
any right to assert an Event of Default hereunder and to pursue
Lender's other rights and remedies with respect thereto.

     21.2. Rights Not Exclusive.
Every right granted to Lender hereunder or under any other Loan
Document or allowed to it at law or in equity shall be deemed
cumulative and may be exercised from time to time.

     21.3. Survival of Agreements.
All covenants and agreements made herein and in the other Loan
Documents shall survive the execution and delivery of this
Agreement, the Notes and other Loan Documents and the making of
every Advance.  All agreements, obligations and liabilities of
Borrower under this Agreement concerning the payment of money to
Lender, including Borrower's obligations under Sections 21.4 and
21.5, but excluding the obligation to repay the Loans and interest
accrued thereon, shall survive the indefeasible repayment in full
of the Loans and interest accrued thereon, the return of the Notes
to Borrower, and the termination of the Commitments.

     21.4. Payment of Expenses.
Borrower agrees to pay or reimburse to Lender all of Lender's
reasonable out-of-pocket costs incurred in connection with Lender's
due diligence review before execution of the Loan Documents; the
negotiation and preparation of any proposal, a commitment letter
and the Loan Documents; the perfection of Lender's Security
Interest in any Collateral, the interpretation of any of the Loan
Documents; the enforcement of Lender's rights and remedies under
the Loan Documents after a Default or Event of Default; any
amendment of or supplementation to any of the Loan Documents; and
any waiver, consent or forbearance with respect to any Default or
Event of Default.  Lender's reasonable out-of-pocket costs may
include but are not limited to the following, to the extent they
are actually paid or incurred by Lender: title insurance fees and
premiums; the cost of searches for Security Interests existing
against Covered Persons; recording and filing fees; appraisal fees;
audit and exam fees; environmental consultant fees; litigation
costs; and all reasonable attorneys' and paralegals' expenses and
reasonable fees; and all reasonable expenses incurred in connection
with any of the foregoing.  Attorneys' and paralegals' expenses may
include but are not limited to filing charges; telephone, data
transmission, facsimile and other communication costs; courier and
other delivery charges; and photocopying charges.  Litigation costs
may include but are not limited to filing fees, deposition costs,
expert witness fees, expenses of service of process, and other such
costs paid or incurred in any administrative, arbitration, or court
proceedings involving Lender and any Covered Person, including
proceedings under the Federal Bankruptcy Code.  All costs which
Borrower is obligated to pay or reimburse Lender are Loan
Obligations payable to Lender are Loan Obligations which are
secured by the Collateral, and are payable on demand by Lender.

     21.5. General Indemnity.

          21.5.1.
     Borrower shall pay, indemnify and hold harmless Lender and its
     respective   directors,  officers,  employees,   agents,   and
     representatives  (the  "Indemnified Parties")  for,  from  and
     against,  and  promptly to reimburse the  Indemnified  Parties
     for,  any and all claims, damages, liabilities, losses,  costs
     and   expenses  (including  reasonable  attorneys'  fees   and
     expenses  and  amounts paid in settlement) incurred,  paid  or
     sustained  by  the  Indemnified Parties  in  connection  with,
     arising out of, based upon or otherwise involving or resulting
     from  any  threatened,  pending  or  completed  action,  suit,
     investigation  or  other proceeding by, against  or  otherwise
     involving the Indemnified Parties and in any way dealing with,
     relating to or otherwise involving this Agreement, any of  the
     other  Loan Documents, or any transaction contemplated  hereby
     or thereby except to the extent that they arise from the gross
     negligence,  bad faith or willful misconduct  of  any  of  the
     Indemnified Parties.  Borrower shall pay, indemnify  and  hold
     harmless  the  Indemnified Parties for, from and against,  and
     promptly  reimburse the Indemnified Parties for, any  and  all
     claims,  damages,  liabilities,  losses,  costs  and  expenses
     (including  reasonable  attorneys'  and  consultant  fees  and
     expenses,   investigation   and  laboratory   fees,   removal,
     remedial,  response and corrective action costs,  and  amounts
     paid  in  settlement)  incurred,  paid  or  sustained  by  the
     Indemnified  Parties as a result of the manufacture,  storage,
     transportation, release or disposal of any Hazardous  Material
     on,  from, over or affecting any of the Collateral or  any  of
     the assets, properties, or operations of any Covered Person or
     any predecessor in interest, directly or indirectly.

          21.5.2.
     The obligations of Borrower under this Section 21.5 shall
     survive the termination of the Commitments, and the
     indefeasible full payment and satisfaction of all of the Loan
     Obligations, and the release of the Collateral.

          21.5.3.
     To the extent that any of the indemnities required from
     Borrower under this Section are unenforceable because they
     violate any Law or public policy, Borrower shall pay the
     maximum amount which it is permitted to pay under applicable
     Law.
          
     21.6. Letters of Credit.
Borrower assumes all risks of the acts or omissions of any
beneficiary of any of the Letters of Credit.  Neither Lender nor
any of its directors, officers, employees, agents, or
representatives shall be liable or responsible for:  (a) the use
which may be made of any of the Letters of Credit or for any acts
or omissions of beneficiary in connection therewith; (b) the
validity, sufficiency or genuineness of documents, or of any
endorsement(s) thereon, even if such documents should in fact prove
to be in any or all respects invalid, insufficient, fraudulent or
forged; (c) payment by Lender against presentation of documents
which, on their face, appear to comply with the terms of any Letter
of Credit, even though such documents may fail to bear any
reference or adequate reference to any such Letter of Credit; or
(d) any other circumstances whatsoever in making or failing to make
payment under any Letter of Credit in connection with which Lender
would, pursuant to the Uniform Customs and Practices for
Documentary Credits (1993 Revision), International Chamber of
Commerce Publication No. 500 (as amended from time to time), be
absolved from liability.  In furtherance and not in limitation of
the foregoing, Lender may accept documents that appear on their
face to be in order, without responsibility for further
investigation, regardless of any notice or information to the
contrary.

     21.7. Changes in Accounting Principles.
If Borrower, at the end of its fiscal year and with the concurrence
of its independent certified public accountants, changes the method
of valuing the Inventory of Borrower, or if any other changes in
accounting principles from those used in the preparation of any of
the Financial Statements are required by or result from the
promulgation of principles, rules, regulations, guidelines,
pronouncements or opinions by the Financial Accounting Standards
Board or the American Institute of Certified Public Accountants (or
successors thereto or bodies with similar functions), and any of
such changes result in a change in the method of calculation of, or
affect the results of such calculation of, any of the financial
covenants, standards or terms found herein, then the parties hereto
agree to enter into and diligently pursue negotiations in order to
amend such financial covenants, standards or terms so as to
equitably reflect such changes, with the desired result that the
criteria for evaluating the financial condition and results of
operations of Borrower shall be the same after such changes as if
such changes had not been made; provided, however, that until such
changes are made, all financial covenants herein and all the
provisions hereof which contemplate financial calculation hereunder
shall remain in full force and effect.

     21.8. Other Security.
Lender may, without notice or demand and without affecting
Borrower's obligations hereunder, from time to time: (a) take from
any Person and hold collateral (other than the Collateral) for the
payment of all or any part of the Loan Obligations and exchange,
enforce and release such collateral or any part thereof; and
(b) accept and hold any endorsement or guaranty of payment of all
or any part of the Loan Obligations and release or substitute any
such endorser or guarantor, or any Person who has given any
Security Interest in any other collateral as security for the
payment of all or any part of the Loan Obligations, or any other
Person in any way obligated to pay all or any part of the Loan
Obligations.

     21.9. Loan Records.
The date and amount of all Advances to Borrower and payments of
amounts due from Borrower under the Loan Documents will be recorded
in the records that Lender normally maintains for such types of
transactions.  The failure to record, or any error in recording,
any of the foregoing shall not, however, affect the obligation of
Borrower to repay the Loans and other amounts payable under the
Loan Documents.  Borrower shall have the burden of proving that
such records are not correct.  Borrower agrees that Lender's books
and records showing the Loan Obligations and the transactions
pursuant to this Agreement shall be admissible in any action or
proceeding arising therefrom, irrespective of whether any Loan
Obligation is also evidenced by a promissory note or other
instrument.  Such statement shall be deemed correct, accurate and
binding on Borrower and an account stated (except for reversals and
reapplications of payments as provided in Section 6.8 and
corrections of errors discovered by Lender), unless Borrower
notifies Lender in writing to the contrary within 30 days after
such statement is rendered.  In the event a timely written notice
of objections is given by Borrower, only the items to which
exception is expressly made will be considered to be disputed by
Borrower.

     21.10. Loan Obligations Payable in Dollars.
All Loan Obligations that are payable in Dollars under the terms of
the Loan Documents shall be payable only in Dollars.  If, however,
to obtain a judgment in any court it is necessary to convert a Loan
Obligation payable in Dollars into another currency, the rate of
exchange used shall be that at which Lender, using its customary
procedures, could purchase Dollars with such other currency in New
York, New York on the Business Day immediately preceding the day on
which such judgment is rendered.  If any sum in another currency is
paid to Lender or received by Lender and applied to a Loan
Obligation payable in Dollars, such Loan Obligation shall be deemed
paid and discharged only to the extent of the amount of Dollars
that Lender, using its customary procedures, is able to purchase in
New York, New York with such sum on the Business Day immediately
following receipt thereof.  Borrower agrees to indemnify Lender
against any loss in Dollars that it may incur on such Loan
Obligation as a result of such payment or receipt and application
to such Loan Obligation.
     
     21.11. Other Security and Guaranties.
Lender may, without notice or demand and without affecting
Borrower's obligations hereunder, from time to time: (a) take from
any Person and hold collateral (other than the Collateral) for the
payment of all or any part of the Loan Obligations and exchange,
enforce and release such collateral or any part thereof; and (b)
accept and hold any endorsement or guaranty of payment of all or
any part of the Loan Obligations and release or substitute any such
endorser or guarantor, or any Person who has given any Security
Interest in any other collateral as security for the payment of all
or any part of the Loan Obligations, or any other Person in any way
obligated to pay all or any part of the Loan Obligations.

22.  Miscellaneous.

     22.1. Notices.
All notices, consents, requests and demands to or upon the
respective parties hereto shall be in writing, and shall be deemed
to have been given or made when delivered in person to those
Persons listed on the signature pages hereof or four days after
being deposited in the United States mail, postage prepaid, or, in
the case of overnight courier services, one Business Day after
delivery to the overnight courier service, or in the case of telex
or telecopy notice, when sent, verification received, in each case
addressed as set forth on the signature pages hereof, or such other
address as either party may designate by notice to the other in
accordance with the terms of this Section.  No notice given to or
demand made on Borrower by Lender in any instance shall entitle
Borrower to notice or demand in any other instance.

     22.2. Confidentiality.
Except as provided in this Section, Lender agrees that it will not
disclose to third parties any Confidential Information.  For the
purposes of this Section 22.2, "Confidential Information" means
information delivered to Lender by or on behalf of Borrower or any
Covered Person in connection with the transactions contemplated by
or otherwise pursuant to this Agreement that is proprietary in
nature and that was clearly marked or labeled or otherwise
adequately identified when received by Lender as being confidential
information of the Borrower or such Covered Person, provided that
such term does not include information that (a) was publicly known
or otherwise known by Lender prior to the time of such disclosure,
(b) subsequently becomes publicly known through no act or omission
by Lender or any person acting on behalf of Lender, (c) otherwise
becomes known to Lender other than through disclosure by Borrower
or any Covered Person or (d) constitutes Financial Statements or
other information delivered to Lender as required hereunder that
are otherwise publicly available.  Lender will maintain the
confidentiality of such Confidential Information in accordance with
procedures adopted by Lender in good faith to protect Confidential
Information delivered to Lender, provided that Lender may deliver
or disclose Confidential Information to (i) its directors,
officers, employees, agents, attorneys and affiliates (to the
extent such disclosure reasonably relates to the administration of
the Loans and the Loan Documents), (ii) its financial advisors and
other professional advisors who agree to hold confidential the
Confidential Information substantially in accordance with the terms
of this Section, (iii) any proposed assignee, participant or
transferee of Lender with respect to the Loans (if such Person has
agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section),
(iv) any Governmental Authority having jurisdiction over Lender, or
(v) any other Person to which such delivery or disclosure may be
necessary or appropriate (a) to effect compliance with any Law,
rule, regulation or order applicable to Lender, (b) in response to
any subpoena or other legal process, (c) in connection with any
litigation to which Lender is a party, or (d) if an Event of
Default has occurred and is continuing, to the extent Lender may
reasonably determine such delivery and disclosure to be necessary
or appropriate in the enforcement or for the protection of the
rights and remedies under this Agreement or any other Loan
Document.

     22.3. Amendments, Waivers and Consents.
Unless otherwise provided herein, no amendment to or waiver of any
provision of this Agreement, or of any of the other Loan Documents,
nor consent to any departure by Borrower herefrom or therefrom,
shall be effective unless it is in writing and signed by authorized
officers of Borrower and Lender; provided, however, that any such
amendment, waiver or consent shall be effective only in the
specific instance and for the purpose for which given.  No notice
to or demand on Borrower in any instance shall entitle Borrower to
any other or further notice or demand in another similar or
different instance.  No failure by Lender to exercise, and no delay
by Lender in exercising, any right, remedy, power or privilege
hereunder shall operate as a waiver thereof, nor shall any single
or partial exercise by Lender of any right, remedy, power or
privilege hereunder preclude any other exercise thereof, or the
exercise of any other right, remedy, power or privilege existing
under any Law or otherwise.
     
     22.4. Rights Cumulative.
Each of the rights and remedies of Lender under this Agreement
shall be in addition to all of its other rights and remedies under
applicable Law, and nothing in this Agreement shall be construed as
limiting any such rights or remedies.

     22.5. Successors and Assigns.
This Agreement shall be binding upon and inure to the benefit of
the parties hereto and all future holders of the Notes and their
respective successors and assigns, except that Borrower may not
assign, delegate or transfer any of its rights or obligations under
this Agreement without the prior written consent of Lender.  With
respect to Borrower's successors and assigns, such successors and
assigns shall include any receiver, trustee or debtor-in-possession
of or for Borrower.

     22.6. Severability.
Any provision of this Agreement which is prohibited, unenforceable
or not authorized in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or lack of authorization without invalidating the
remaining provisions hereof or affecting the validity,
enforceability or legality of such provision in any other
jurisdiction unless the ineffectiveness of such provision would
result in such a material change as to cause completion of the
transactions contemplated hereby to be unreasonable.

     22.7. Counterparts.
This Agreement may be executed by the parties hereto on any number
of separate counterparts, and all such counterparts taken together
shall constitute one and the same instrument.  It shall not be
necessary in making proof of this Agreement to produce or account
for more than one counterpart signed by the party to be charged.

     22.8. Governing Law; No Third Party Rights.
This Agreement, the other Loan Documents and the Notes and the
rights and obligations of the parties hereunder and thereunder
shall be governed by and construed and interpreted in accordance
with the internal Laws of the State of Missouri applicable to
contracts made and to be performed wholly within such state,
without regard to choice or conflict of laws provisions; except
that the provisions of the Loan Documents pertaining to the
creation or perfection of Security Interests or the enforcement of
rights of Lender in Collateral located in a State other than the
State of Missouri shall be governed by the laws of such other
State.  This Agreement is solely for the benefit of the parties
hereto and their respective successors and assigns, and no other
Person shall have any right, benefit, priority or interest under,
or because of the existence of, this Agreement.

     22.9. Counterpart Facsimile Execution.
For purposes of this Agreement, a document (or signature page
thereto) signed and transmitted by facsimile machine or telecopier
is to be treated as an original document.  The signature of any
Person thereon, for purposes hereof, is to be considered as an
original signature, and the document transmitted is to be
considered to have the same binding effect as an original signature
on an original document.  At the request of any party hereto, any
facsimile or telecopy document is to be re-executed in original
form by the Persons who executed the facsimile or telecopy
document.  No party hereto may raise the use of a facsimile machine
or telecopier or the fact that any signature was transmitted
through the use of a facsimile or telecopier machine as a defense
to the enforcement of this Agreement or any amendment or other
document executed in compliance with this Section.

     22.10. No Other Agreements.
There are no other agreements between Lender and Borrower, oral or
written, concerning the subject matter of the Loan Documents, and
all prior agreements concerning the same subject matter, including
any proposal or Commitment Letter, are merged into the Loan
Documents and thereby extinguished.

     22.11. Negotiated Transaction.
Borrower and Lender represent each to the others that in the
negotiation and drafting of this Agreement and the other Loan
Documents they have been represented by and have relied upon the
advice of counsel of their choice.  Borrower and Lender affirm that
their counsel have both had substantial roles in the drafting and
negotiation of this Agreement and Lender affirms that its counsel
has participated in the drafting and negotiation of this Agreement;
therefore, this Agreement will be deemed drafted by all of Borrower
and Lender and the rule of construction to the effect that any
ambiguities are to be resolved against the drafter will not be
employed in the interpretation of this Agreement.

     22.12.
MANDATORY ARBITRATION.

          22.12.1.
     Any controversy or claim between or among the parties hereto
     arising out of or relating to this Agreement or the other Loan
     Documents, including any claim based on or arising from an
     alleged tort, shall be determined by binding arbitration in
     accordance with the Federal Arbitration Act (or if not
     applicable, the applicable state law), the Rules of Practice
     and Procedure for the Arbitration of Commercial Disputes of
     Judicial Arbitration and Mediation Services, Inc., predecessor
     in interest to Endispute, Inc., doing business as
     "J.A.M.S./Endispute" and the "Special Rules" set forth below.
     In the event of any inconsistency, the Special Rules shall
     control.  Judgment upon any arbitration award may be entered
     in any court having jurisdiction.  Any party to this Agreement
     may bring an action, including a summary or expedited
     proceeding, to compel arbitration of any controversy or claim
     to which this Agreement applies in any court having
     jurisdiction over such action.

          22.12.2.
     The arbitration shall be conducted in the St. Louis, Missouri
     and administered by J.A.M.S./Endispute who will appoint an
     arbitrator; if J.A.M.S./Endispute is unable or legally
     precluded from administering the arbitration, then the
     American Arbitration Association will serve.  All arbitration
     hearings will be commenced within ninety (90) calendar days of
     the demand for arbitration; further, the arbitrator shall
     only, upon a showing of cause, be permitted to extend the
     commencement of such hearing for up to an additional sixty
     (60) calendar days.

          22.12.3.
     Nothing in this Agreement shall be deemed to (i) limit the
     applicability of any otherwise applicable statutes of
     limitation or repose and any waivers contained in this
     Agreement; or (ii) be a waiver by Lender of the protection
     afforded to it by 12 U.S.C. Sec. 91 or any substantially
     equivalent state law; or (iii) limit the right of Lender
     (A) to exercise self help remedies such as (but not limited
     to) setoff, or (B) foreclose against any Collateral or (C) to
     obtain from a court provisional or ancillary remedies such as
     (but not limited to) injunctive relief or the appointment of a
     receiver.  Lender may exercise such self help rights,
     foreclose upon such Collateral, obtain such provisional or
     ancillary remedies, or take any other action with respect to
     the Collateral permitted by law or equity against Borrower or
     any other Person liable for all or any portion of the Loan
     Obligations, before, during or after the pendency of any
     arbitration proceeding brought pursuant to this Agreement or
     any of the other Loan Documents.  Neither the exercise of self
     help remedies nor the institution or maintenance of an action
     for foreclosure or provisional or ancillary remedies shall
     constitute a waiver of the right of any party, including the
     claimant in any such action, to arbitrate the merits of the
     controversy or claim occasioning resort to such remedies.  No
     provision herein or in this Agreement or the Loan Documents
     regarding submission to jurisdiction, choice of forum, jury
     trial waiver, and/or venue in any court is intended or shall
     be construed to be in derogation of the provisions herein or
     therein for arbitration of any controversy or claim.

     22.13. Acknowledgment of Licensing Arrangements.
Nothing contained in this Agreement or in the Loan Documents shall
be construed as prohibiting Borrower from entering into licensing
or other contractual arrangements with respect to its software and
patents for the purpose of creating revenue for Borrower in the
ordinary course of Borrower's business as presently conducted.

     22.14. CHOICE OF FORUM.
Subject only to the exception in the next sentence, Borrower and
Lender hereby agree to the exclusive jurisdiction of the federal
court of the Eastern District of Missouri and the state courts of
Missouri located in St. Louis County, Missouri, and waive any
objection based on venue or forum non conveniens with respect to
any action instituted therein, and agree that any dispute
concerning the relationship between Lender and Borrower or the
conduct of any of them in connection with this Agreement or
otherwise shall be heard only in the courts described above.
Notwithstanding the foregoing: (1) Lender shall have the right to
bring any action or proceeding against Borrower or its property in
any courts of any other jurisdiction Lender deem necessary or
appropriate in order to realize on the Collateral, real estate, or
other security for the Loan Obligations, and (2) each of the
parties hereto acknowledges that any appeals from the courts
described in the immediately preceding sentence may have to be
heard by a court located outside those jurisdictions.   Borrower
shall cause each Covered Person to comply with the terms of this
Section.

     22.15. SERVICE OF PROCESS.
Borrower hereby waives personal service of any and all process upon
it  and  consents that all such service of process may be  made  by
registered mail (return receipt requested) directed to Borrower  at
its address set forth on the signature pages hereof, and service so
made shall be deemed to be completed five days after the same shall
have  been  so  deposited  in the U.S. mails  (or,  if  Lender  has
exercised its right to receive and open Borrower's mail as provided
herein, on the date service of process is received by Borrower); or
at  Lender's option, by service upon CT Corporation, which Borrower
irrevocably  appoints  as  Borrower's  agent  for  the  purpose  of
accepting service of process within the State of Missouri.   Lender
shall  promptly  forward by registered mail any process  so  served
upon  said agent to Borrower at its address on the signature  pages
hereof.   Nothing in this section shall affect the right of  Lender
to  serve  legal  process  in any other manner  permitted  by  Law.
Borrower  shall  cause each other Covered Person to  agree  to  the
terms of this Section.

     22.16. JURY TRIAL.
Borrower and Lender hereby waive any right to trial by jury of any
claim, demand, action or cause of action (1) arising under this
Agreement or any other Loan Document, or (2) in any way connected
with or related or incidental to the dealings of the parties hereto
or either of them in respect of this Agreement or any other Loan
Document, or the transactions related hereto or thereto, in each
case whether now existing or hereafter arising, and whether
sounding in contract or tort or otherwise.  Borrower and Lender
agree and consent that any such claim, demand, action or cause of
action shall be decided by court trial without a jury and that
either may file an original counterpart or a copy of this Agreement
with any court as written evidence of the consent of the parties
hereto to the waiver of their right to trial by jury.  Borrower
shall cause each other Covered Person to agree to the terms of this
Section.

     22.17. Incorporation By Reference.
All of the terms of the other Loan Documents are incorporated in
and made a part of this Agreement by this reference.

     22.18. Statutory Notice.
The following notice is given pursuant to Section 432.045 of the
