(2)    INTERIM FINANCIAL STATEMENTS PRESENTATION

    The accompanying interim financial statements are unaudited and have been
prepared by the Company pursuant to the rules and regulations of the
Securities and Exchange Commission ("SEC") regarding interim financial
reporting.  Accordingly, they do not include all of the information and

fair presentation of the results of the interim periods.  The results of

(4)    NET INCOME PER COMMON SHARE

    In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, Earnings per Share.  Statement 128
replaced the previously reported primary and fully diluted earnings per share
with basic and diluted earnings per share.  Unlike primary earnings per share,
basic earnings per share excludes any dilutive effects of options, warrants,
and convertible securities.  Diluted earnings per share is very similar to the
previously reported fully diluted earnings per share.  All earnings per share
amounts for all periods have been presented, and where necessary, restated to
conform to the Statement 128 requirements.

(5)    INITIAL PUBLIC OFFERING

    On November 26, 1997, the Company completed an initial  public offering of
1,250,000 Common Shares  at an offering price of $8.00 per share.  On December
19, 1997, the underwriters exercised an option to purchase an additional
100,000 Common Shares.  The net proceeds to the Company from the public
offering and the exercise of the over-allotment option by the underwriters,
after deducting the underwriting discounts and commissions and offering
expenses payable by the Company, were approximately $9.4 million.  Upon the
closing of the offering, all of the Company's outstanding Convertible
Preferred Shares were converted into 752,399 Common Shares.

(6)    ACQUISITION

    On October 31, 1997, the Company acquired all of the outstanding capital
stock of Vetronics, Inc. ("Vetronics"), which manufactures, markets and sells,
electrocardiograph and vital sign monitors for small to midsize animals.  The
total purchase price consisted of $200,000 in cash, $150,000 in notes payable
on July 1, 1998 and a contingent amount to be based upon the profitability of
sales from products manufactured by Vetronics during the next two years.  The
Company believes that the addition of these products will enhance its position
as a producer of physiology instrumentation.

(7)    SUBSEQUENT EVENT

    On April 2, 1998, the Company agreed to purchase three Benchtop Triple
Stage Quadruple Mass Spectrometers. The purchase price of these instruments is
approximately $770,000, with payment terms of 50% due upon placement of the
order, 40% due upon delivery and 10% due upon acceptance of the instruments.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1998 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1997

    Total revenue for the three months ended March 31, 1998 increased 22.0% to
approximately $4.5 million from approximately $3.6 million for the three
months ended March 31, 1997.  The net increase of approximately $900,000 was
primarily due to increased revenue from services, which increased to
approximately $1.6 million in the three months ended March 31, 1998 from
approximately $1.1 million in the three months ended March 31, 1997 as a
result of the expansion of types and volume of services provided by the
Company.  During this same period, product revenue increased to approximately
$2.9 million for the three months ended March 31, 1998 from approximately $2.5
million for the three months ended March 31, 1997 primarily as a result of
sales of a new line of physiology monitoring products acquired in connection
with the acquisition of Vetronics on October 31, 1997.

    Total cost of revenue for the three months ended March 31, 1998 increased
25.0% to approximately $1.9 million from approximately $1.5 million for the
three months ended March 31, 1997.  This increase of approximately $400,000
was primarily due to the additional cost of revenue related to the services
unit.  Cost of product revenue increased to 32.5% as a percentage of product
revenue for the three months ended March 31, 1998 from 31.6% of product
revenue for the three months ended March 31, 1997, due to a change in product
mix.  Cost of service revenue decreased to approximately 61.0% as a percentage
of service revenue for the three months ended March 31, 1998 from
approximately 63.6% of services revenue for the three months ended March 31,
1997 due to an increase in the level of services revenue.

    Selling expenses for the three months ended March 31, 1998 increased 13.9%
to approximately $1,100,000 from approximately $966,000 for the three months
ended March 31, 1997 due to the promotion of the new homocysteine kit.
Research and development expenses for the three months ended March 31, 1998
increased 74.9% to approximately $598,000 from approximately $342,000 for the
three months ended March 31, 1997 due to the acceleration of product
development and increased activity in the NIH and NASA grant projects.
General and administrative expenses for the three months ended March 31, 1998
increased 45.8% to approximately $525,000 from approximately $360,000 for the
three months ended March 31, 1997, primarily as a result of increased property
taxes incurred in connection with the Company's purchase and construction of
additional facilities as well as increased general and administrative expenses
related to the Company's defense of a patent infringement suit.

    Other income (expense), net, was approximately $23,000 in the three months
ended March 31, 1998, as compared to approximately $(9,000) in the three
months ended March 31, 1997 as a result of a reduction in net interest expense
due to an increase in cash and cash equivalents resulting from the initial
public offering.

    The Company's effective tax rate for the three months ended March 31, 1998
was 34.0% as compared to 41.2% for the three months ended March 31, 1997.
This decrease was due in part, to improving profitability from operations in
the United Kingdom.

SIX MONTHS ENDED MARCH 31, 1998 COMPARED WITH SIX MONTHS ENDED MARCH 31, 1997

    Total revenue for the six months ended March 31, 1998 increased 22.6% to
approximately $8.8 million from approximately $7.2 million for the six months
ended March 31, 1997.  The net increase of approximately $1,600,000 was
primarily due to increased revenue from services, which increased to
approximately $3.3 million in the six months ended March 31, 1998 from
approximately $2.3 million in the six months ended March 31, 1997 as a result
of the expansion of types and volume of services provided by the Company.
During this same period, product revenue increased to approximately $5.5
million for the six months ended March 31, 1998 from approximately $4.9
million for the six months ended March 31, 1997 primarily as a result of
sales of a new line of physiology monitoring products acquired in connection
with the acquisition of Vetronics on October 31, 1997.
 .

    Total cost of revenue for the six months ended March 31, 1998 increased
31.1% to approximately $3.7 million from approximately $2.9 million for the
six months ended March 31, 1997.  This increase of approximately $800,000 was
primarily due to the additional cost of revenue related to the services unit.
Cost of product revenue increased to 34.2% as a percentage of product revenue
for the six months ended March 31, 1998 from 30.1% of product revenue for the
six months ended March 31, 1997, due to a change in product mix.  Cost of
services revenue decreased to approximately 56.9% as a percentage of service
revenue for the six months ended March 31, 1998 from approximately 60.6% of
services revenue for the six months ended March 31, 1997 due to an increase in
the level of services revenue.

    Selling expenses for the six months ended March 31, 1998 increased 6.1% to
approximately $2,171,000 from approximately $2,046,000 for the six months
ended March 31, 1997 due to the promotion of the new homocysteine kit.
Research and development expenses for the six months ended March 31, 1998
increased 52.1% to approximately $1,074,000 from approximately $706,000 for
the six months ended March 31, 1997 due to the acceleration of product
development and increased activity in the NIH and NASA grant projects.
General and administrative expenses for the six months ended March 31, 1998
increased 52.0% to approximately $1,137,000 from approximately $748,000 for
the six months ended March 31, 1997, primarily as a result of increased
property taxes incurred in connection with the Company's purchase and
construction of additional facilities as well an increased general and
administrative expenses related to the Company's defense of a patent
infringement suit.


    Other income (expense), net, was approximately $46,000 in the six months
ended March 31, 1998, as compared to approximately $(37,000) in the six months
ended March 31, 1997
 as a result of a reduction in net interest expense due to an increase in cash
and cash equivalents resulting from the initial public offering.

    The Company's effective tax rate for the six months ended March 31, 1998
was 38.8% as compared to 41.2% for the six months ended March 31, 1997.  This
decrease was due in part, to improving profitability from operations in the
United Kingdom.

LIQUIDITY AND CAPITAL RESOURCES

    At March 31, 1998, the Company had cash and cash equivalents of
approximately $3.0 million compared to cash and cash equivalents of
approximately $161,000 at September 30, 1997.  The increase in cash resulted
primarily from the Company's initial public offering of Common Shares in
November of 1997.

    The Company's net cash provided by operating activities was approximately
$740,000 for the six months ended March 31, 1998 as compared to approximately
$380,000 for the first six months of 1997.  The positive cash flow from
operations during the six months ended March 31, 1998 was primarily the result
of net income of approximately $427,000 plus non-cash charges of approximately
$411,000 partially offset by a net change of approximately $98,000 in
operating assets and liabilities.  The most significant increase in operating
assets related to inventory, which increased to approximately $2.1 million at
March 31, 1998 from approximately $1.9 million at September 30, 1997.

    Cash used by investing activities increased to approximately $1.7 million
for the six months ended March 31, 1998 from approximately $1.2 million for
the six months ended March 31, 1997, primarily as a result of the Company's
construction of additional facilities.  Cash provided by financing activities
for the six months ended March 31, 1998 was approximately $3.8 million due to
the initial public offering in November of 1997, partially offset by the
reduction of debt.

    Total expenditures by the Company for property and equipment were
approximately $1,218,000 and $1,397,000 for the six months ended March 31,
1997 and 1998, respectively.  Expenditures made in connection with the
expansion of the Company's operating facilities and purchases of laboratory
equipment account for the largest portions of these expenditures.  The Company
anticipates increased levels of capital expenditures in fiscal 1998 and fiscal
1999 in connection with the renovation and construction of additional
facilities and the purchase of additional laboratory equipment.  The Company,
however, currently has no firm commitments for capital expenditures other than
in connection with the expansion of the Company's facilities.  The Company
also expects to make other investments to expand its operations through
internal growth and strategic acquisitions, alliances and joint ventures.

    Based on its current business activities, the Company believes that cash
generated from its operations, amounts available under its existing bank lines
of credit and the remaining net proceeds from its initial public offering will
be sufficient to fund its anticipated working capital and capital expenditure
requirements.

    The Company has a $7.5 million  bank line of credit agreement, which
expires March 1, 1999.   Interest is charged at the prime rate (8.5% at March
31, 1998).  The line is not currently being utilized.  The line is
collateralized by substantially all inventories and accounts receivable.

EFFECT OF NEW ACCOUNTING PRONOUNCEMENT

    In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No.  128, Earnings per Share.  Statement 128
replaced the previously reported primary and fully diluted earnings per share
with basic and diluted earnings per share.  Unlike primary earnings per share,
basic earnings per share excludes any dilutive effects of options, warrants,
and convertible securities.  Diluted earnings per share is very similar to the
previously reported fully diluted earnings per share.  All earnings per share
amounts for all periods have been presented, and where necessary, restated to
conform to the Statement 128 requirements.


    PART II - OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

    In April, 1997, CMA Microdialysis Holding A.B. ("CMA") filed an action
against the Company in the United States District Court for the District of
New Jersey which CMA alleged that the Company's microdialysis probes infringe
U. S. Patent No. 4,694,832.  The Company has filed an answer in which it
denied infringement and in which it asserted that the patent on which CMA
relies is invalid.  Sales of the product in question accounted for less than
$75,000 of the Company's revenues in fiscal 1997.  The matter is now in the
discovery stage.  Management intends to continue a vigorous defense of CMA's
claims, and believes that the ultimate outcome of this matter will not have a
material adverse effect on the Company's financial condition or result of
operations, but legal expenses associated with the defense of this suit may
have an adverse effect on current earnings.

ITEM 2.    CHANGES IN SECURITIES AND USE OF PROCEEDS.


    In the first and second fiscal quarter, the Company issued an aggregate of
101,343 Common Shares to certain employees and members of the Company's Board
of Directors upon the exercise of stock options for an aggretate $158,459.29.
The issuance of these Common Shares was exempt from registration under the
Securities Act of 1933, as amended, by reason of Section 4(2) thereof and Rule
701 of the Securities and Exchange Commission (the "SEC").

    On November 24, 1997, the SEC declared effective the Company's
Registration Statement on Form S-1, File Number 333-36429.  Item 2 of Part II
of the Company's Form 10-Q for the period ended December 31, 1997 set forth
information regarding the Company's proceeds from the offering pursuant to
such registration statement and the Company's use of such proceeds.  The
following information has changed since such disclosure.


    The net proceeds received by the Company from the offering were $9,362,000
after deducting expenses paid by the Company of $1,438,000 consisting of
$756,000 for underwriting discounts and commissions and $682,000 for legal,
accounting and printing fees.

    As of March 31, 1998, the Company had used approximately $6,600,000 of the
net proceeds from the offering to repay indebtedness.  The balance of the net
proceeds, or approximately $2,800,000, was invested in money market funds.

ITEM 4.    SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS.

    At the annual meeting of shareholders of the Company held on January 22,
1998, the following actions were taken:

account),  including  all  accounts  held  jointly  with  someone else and all
accounts  Grantor  may  open in the future.  Grantor authorizes Lender, to the
extent  permitted  by  applicable  law,  to  charge or setoff all Indebtedness
against  any  and  all  such  accounts.

OBLIGATIONS  OF GRANTOR.  Grantor represents, warrants and covenants to Lender
as  follows:

incorporation.    Grantor  has its chief executive office at 2701 KENT AVENUE,
WEST  LAFAYETTE,  IN  47906.   Grantor will notify Lender of any change in the
location  of  Grantor's  chief  executive  office.

AUTHORIZATION.   The execution, delivery, and performance of this Agreement by
Grantor  have  been  duly authorized by all necessary action by Grantor and do
not conflict with, result in a violation of, or constitute a default under (a)
any  provision of its articles of incorporation or organization, or bylaws, or
any  agreement  or  other  instrument  binding  upon  Grantor  or (b) any law,
governmental  regulation,  court  decree,  or  order  applicable  to  Grantor.


PERFECTION  OF  SECURITY  INTEREST.   Grantor agrees to execute such financing
statements  and  to  take  whatever  other  actions are requested by Lender to
perfect  and  continue  Lender's  security  interest  in the Collateral.  Upon
request of Lender, Grantor will deliver to Lender any and all of the documents
evidencing  or  constituting  the  Collateral,  and Grantor will note Lender s
interest  upon  any  and  all  chattel  paper  if  not delivered to Lender for
possession  by  Lender.    Grantor  here by irrevocably appoints Lender as its
attorney  in  fact  for  the  purpose  of executing any documents necessary to
perfect  or  to  continue  the  security  interest  granted in this Agreement.
Lender  may  sign  and  file financing statements without Grantor's signature.
Lender may at any time, and without further authorization from Grantor, file a
carbon,  photographic  or  other reproduction of any financing statement or of
this  Agreement  for  use  as  a  financing statement.  Grantor will reimburse
Lender  for  all  expenses  for  the  perfection  and  the continuation of the
perfection  of  Lender's  security  interest  in  the Collateral.  Grantor has
disclosed  to  Lender  all  tradenames  and  assumed  names  currently used by
Grantor,  all tradenames and assumed names used by Grantor within the previous
six  (6)  years and all of Grantor s current business locations.  Grantor will
notify  Lender in writing at least thirty (30) days prior to the occurrence of
any  of  the  following,  (i)  any  changes in Grantor s name, tradename(s) or
assumed  name(s),  or (ii) any change in Grantor's business location(s) or the
location  of  any  of  the  Collateral.

NO  VIOLATION.   The execution and delivery of this Agreement will not violate
any law or agreement governing Grantor or to which Grantor is a party, and its
certificate  or  articles of incorporation and bylaws do not prohibit any term
or  condition  of  this  Agreement.

ENFORCEABILITY  OF  COLLATERAL.    To  the  extent  the Collateral consists of
accounts, chattel paper, or general intangibles, the Collateral is enforceable
in  accordance  with  its terms, is genuine, and complies with applicable laws
concerning  form,  content  and  manner  of preparation and execution, and all
persons  appearing  to  be  obligated  on  the  Collateral  have authority and
capacity  to  contract  and  are in fact obligated as they appear to be on the
Collateral.  At the time any account becomes subject to a security interest in
favor of Lender, the account shall be a good and valid account representing an
undisputed,  bona  fide  indebtedness  incurred  by  the  account  debtor, for
merchandise  held  subject  to delivery instructions or theretofore shipped or
delivered  pursuant  to  a  contract  of  sale,  or  for  services theretofore
performed  by Grantor with or for the account debtor; Grantor will not adjust,
settle,  compromise,  amend or modify any account, except in good faith and in
the  ordinary  course  of  business;  provided,  however, this exception shall
automatically  terminate  upon  the  occurrence of an Event of Default or upon
Lender's  written  request.

LOCATION  OF THE COLLATERAL.  Grantor, upon request of Lender, will deliver to
Lender  in  form  satisfactory  to  Lender  a  schedule of real properties and
Collateral  locations  relating  to  Grantor's  operations,  including without
limitation  the  following:  (a) all real property owned or being purchased by
Grantor;  (b)  all  real  property  being rented or leased by Grantor; (c) all
storage  facilities  owned,  rented, leased, or being used by Grantor; and (d)
all  other  properties  where  Collateral is or may be located.  Except In the
ordinary  course of its business, Grantor shall not remove the Collateral from
its  existing  locations  without  the  prior  written  consent  of  Lender.

REMOVAL  OF  COLLATERAL.   Grantor shall keep the Collateral (or to the extent
the  Collateral  consists of intangible property such as accounts, the records
concerning  the Collateral) at Grantor's address shown above, or at such other
locations  as  are acceptable to Lender.  Except in the ordinary course of its
business,  including  the  sales  of  inventory,  Grantor shall not remove the
Collateral  from  its  existing locations without the prior written consent of
Lender.    To  the  extent  that the Collateral consists of vehicles, or other
titled  property,  Grantor  shall  not  take  or permit any action which would
require  application  for  certificates  of title for the vehicles outside the
State  of  Indiana,  without  the  prior  written  consent  of  Lender.


TRANSACTIONS  INVOLVING  COLLATERAL.    Except  for inventory sold or accounts
collected  in  the  ordinary  course  of Grantor's business, Grantor shall not
sell,  offer  to  sell,  or  otherwise  transfer or dispose of the Collateral.
While  Grantor  is  not  in  default  under  this  Agreement, Grantor may sell
Inventory,  but only in the ordinary course of its business and only to buyers
who  qualify  as  a  buyer  in the ordinary course of business.  A sale in the
ordinary  course  of Grantor's business does not include a transfer in partial
or  total  satisfaction of a debt or any bulk sale.  Grantor shall not pledge,
mortgage,  encumber  or  otherwise  permit the Collateral to be subject to any
lien,  security  interest,  encumbrance,  or  charge,  other than the security
interest  provided for in this Agreement, without the prior written consent of
Lender.    This  includes  security  interests  even if junior in right to the
security interests granted under this Agreement.  Unless waived by Lender, all
proceeds from any disposition of the Collateral (for whatever reason) shall be
held  in  trust  for  Lender and shall not be commingled with any other funds;
provided  however,  this requirement shall not constitute consent by Lender to
any  sale  or  other  disposition.    Upon  receipt, Grantor shall immediately
deliver  any  such  proceeds  to  Lender.

TITLE.   Grantor represents and warrants to Lender that it is the owner of the
Collateral  and  holds  good  and marketable title to the Collateral, free and
clear of all liens and encumbrances except for the lion of this Agreement.  No
financing  statement  covering  any of the Collateral is on file in any public
office  other  than  those which reflect the security interest created by this
Agreement or to which Lender has specifically consented.  Grantor shall defend
Lender's  rights in the Collateral against the claims and demands of all other
persons.

COLLATERAL  SCHEDULES  AND  LOCATIONS.   As often as Lender shall require, and
insofar  as  the  Collateral  consists  of  accounts  and general intangibles,
Grantor  shall  deliver to Lender schedules of such Collateral, including such
information  as  Lender  may  require,  including without limitation names and
addresses  of  account debtors and agings of accounts and general Intangibles.
Insofar  as  the Collateral consists of inventory and equipment, Grantor shall
deliver to Lender, as often as Lender shall require, such lists, descriptions,
and  designations  of  such  Collateral  as Lender may require to identify the
nature,  extent,  and  location  of  such  Collateral.

MAINTENANCE AND INSPECTION OF COLLATERAL.  Grantor shall maintain all tangible
Collateral  in  good  condition and repair.  Grantor will not commit or permit
damage  to  or  destruction  of  the Collateral or any part of the Collateral.
Lender  and  its designated representatives and agents shall have the right at
all  reasonable  times  to examine, inspect, and audit the Collateral wherever
located.    Grantor shall immediately notify Lender of all cases involving the
return,  rejection,  repossession,  loss or damage of or to any Collateral; of
any  request  for  credit  or  adjustment or of any other dispute arising with
respect  to  the  Collateral;  and  generally  of  all  happenings  and events
affecting  the  Collateral  or  the  value  or  the  amount of the Collateral.


TAXES,  ASSESSMENTS  AND  LIENS.    Grantor  will  pay  when  due  all  taxes,
assessments and governmental charges or levies upon the Collateral and provide
Lender  evidence  of  such payment upon its request.  Grantor may withhold any
such  payment  or  may  elect  to contest any lien if Grantor is in good faith
conducting  an  appropriate proceeding to contest the obligation to pay and so
long  as  Lender's  interest  in the Collateral is not jeopardized in Lender's
sole  opinion.    If  the  Collateral  is  subjected  to  a  lien which is not
discharged within fifteen (15) days, Grantor shall deposit with Lender cash, a
sufficient  corporate  surety bond or other security satisfactory to Lender in
an amount adequate to provide for the discharge of the lien plus any interest,
costs,  attorneys'  fees  or  other  charges  that could accrue as a result of
foreclosure  or  sale  of the Collateral.  In any contest Grantor shall defend
itself  and  Lender  and  shall  satisfy  any  final  adverse  judgment before
enforcement  against  the  Collateral.    Grantor  shall  name  Lender  as  an
additional obligee under any surety bond furnished in the contest proceedings.

COMPLIANCE  WITH  GOVERNMENTAL  REQUIREMENTS.   Grantor is conducting and will
continue  to  conduct  Grantor's  businesses  in  material compliance with all
federal,  state  end  local  laws,  statutes,  ordinances, rules, regulations,
orders,  determinations and court decisions applicable to Grantor's businesses
and to the production, disposition or use of the Collateral, including without
limitation,  those  pertaining to health and environmental matters such as the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
as  amended  by  the  Superfund  Amendments  and  Reauthorization  Act of 1986
(collectively,  together  with  any  subsequent amendments, hereinafter called
"CERCLA"),  the  Resource Conservation and Recovery Act of 1976, as amended by
the Used Oil Recycling Act of 1980, the Solid Waste Disposal Act Amendments of
1980,  and  the  Hazardous  Substance  Waste Amendments of 1984 (collectively,
together  with any subsequent amendments, hereinafter called "RCRA").  Grantor
represents  and  warrants  that  (i)  none of the operations of Grantor is the
subject  of  a  federal,  state  or local investigation evaluating whether any
material  remedial action is needed to respond to a release or disposal of any
toxic or hazardous substance or solid waste into the environment; (ii) Grantor
has not filed any notice under any federal, state or local law indicating that
Grantor  is  responsible for the release into the environment, the disposal on
any  premises  in  which  Grantor is conducting its businesses or the improper
storage,  of  any material amount of any toxic or hazardous substance or solid
waste  or  that  any such toxic or hazardous substance or solid waste has been
released,  disposed  of  or  is  improperly stored, upon any premises on which
Grantor  is  conducting  its  businesses; and (iii) Grantor otherwise does not
have  any  known  material contingent liability in connection with the release
into  the  environment, disposal or the improper storage, of any such toxic or
hazardous  substance  or  solid  waste.    The terms "hazardous substance" and
"release",  as  used  herein, shall have the meanings specified in CERCLA, and
the  terms  "solid  waste"  and  "disposal",  as  used  herein, shall have the
meanings  specified  in  RCRA;  provided, however, that to the extent that the
laws  of  the  State  of  Indiana  establish meanings for such terms which are
broader  than  that  specified in either CERCLA or RCRA, such broader meanings
shall apply.  The representations and warranties contained herein are based on
Grantor's  due  diligence in investigating the Collateral for hazardous wastes
and  substances.  Grantor  hereby  (a)  releases  and waives any future claims
against  Lender  for  indemnity  or  contribution in the event Grantor becomes
liable  for  cleanup  or  other  costs  under any such laws, and (b) agrees to
indemnify  and  hold  harmless  Lender  against  any and all claims and losses
resulting  from a breach of this provision of this Agreement.  This obligation
to indemnify shall survive the payment of the Indebtedness and the termination
of  this  Agreement.

MAINTENANCE  OF  CASUALTY  INSURANCE.   Grantor shall procure and maintain all
risk  insurance,  including  without  limitation  fire,  theft  and  liability
coverage together with such other insurance as Lender may require with respect
to the Collateral, in form, amounts, coverages and basis reasonably acceptable
to  Lender  and  issued  by  a  company  or companies reasonably acceptable to
Lender.   Grantor, upon request of Lender, will deliver to Lender from time to
time the policies or certificates of insurance in form satisfactory to Lender,
including  stipulations  that  coverages  will  not be cancelled or diminished
without  at  least  thirty  (30)  days'  prior written notice to Lender and no
including any disclaimer of the insurer's liability for failure to give such a
notice.    Each  insurance  policy also shall include an endorsement providing
that  coverage  in favor of Lender will not be impaired in any way by any act,
omission  or  default  of Grantor or any other person.  In connection with all
policies  covering  assets  in  which  Lender  holds  or is offered a security
interest,  Grantor  will  provide  Lender  with  such  loss  payable  or other
endorsements as Lender may require.  If Grantor at any time fails to obtain or
maintain any insurance as require( under this Agreement, Lender may (but shall
not  be  obligated  to)  obtain  such  insurance  as Lender deems appropriate,
including  if it so chooses "single interest insurance," which will cover only
Lender's  interest  in  the  Collateral.

APPLICATION  OF  INSURANCE  PROCEEDS.  Grantor shall promptly notify Lender of
any  loss  or  damage  to  the  Collateral.   Lender may make proof of loss if
Grantor  fails  to  do  so  within  fifteen  (l  5) days of the casualty.  All
proceeds  of  any  insurance  on  the  Collateral,  including  accrue proceeds
thereon,  shall  be  held  by  Lender  as  part  of the Collateral.  If Lender
consents  to  repair  or  replacement  of the damaged or destroyed Collateral,
Lender shall, upon satisfactory proof of expenditure, pay or reimburse Grantor
from the proceeds for the reasonable cost of repair or restoration.  If Lender
does  not  consent  to  repair  or replacement of the Collateral, Lender shall
retain a sufficient amount of the proceeds to pay all of the Indebtedness, and
shall  pay the balance to Grantor.  Any proceeds which have not been disbursed
within  six (6) months after their receipt and which Grantor has not committed
to  the  repair  or  restoration of the Collateral shall be used to prepay the
Indebtedness.    Application  of  insurance  proceeds  to  the  payment of the
Indebtedness  will not extend, postpone or waive an payments otherwise due, or
change  the  amount of such payments to be made and proceeds may be applied in
such  order  and  such  amounts  as  Lender  may  elect.

SOLVENCY  OF GRANTOR.   As of the date hereof, and after giving effect to this
Agreement  and the completion of all other transaction contemplated by Grantor
at  the  time  of  the execution of this Agreement, (i) Grantor is and will be
solvent,  (ii)  the  fair  salable  value of Grantor's assets exceeds and will
continue  to  exceed  Grantor's liabilities (both fixed and contingent), (iii)
Grantor  is  paying  and  will  continue  to  be able to pay its debts as they
mature,  and  (iv)  if Grantor is not an individual, Grantor has and will have
sufficient  capital  to  carry  on  Grantor's businesses and all businesses in
which  Grantor  is  about  to  engage.


LIEN  NOT  RELEASED.  The lien, security interest and other security rights of
Lender  hereunder  shall  not  be  impaired  by  any indulgence, moratorium or
release  granted  by  Lender, including but not limited to, the following: (a)
any  renewal,  extension, increase or modification of any of the Indebtedness;
(b)  any  surrender,  compromise,  release,  renewal,  extension,  exchange or
substitution  granted  in respect of any of the Collateral; (c) any release or
indulgence  granted  to  any  endorser,  guarantor  or  surety  of  any of the
Indebtedness;  (d)  any  release  of  any  other  collateral  for  any  of the
indebtedness;  (e) any acquisition of any additional collateral for any of the
Indebtedness;  and  (f)  any waiver or failure to exercise any right, power or
remedy  granted  herein,  by  law  or  in  any  of  the  Related  Documents.

REQUEST  FOR ENVIRONMENTAL INSPECTIONS.  Upon Lender's reasonable request from
time  to time, Grantor will obtain at Grantor's expense an inspection or audit
report(s)  addressed  to Lender of Grantor's operations from an engineering or
consulting  firm  approved  by  Lender,  indicating the presence or absence of
toxic  and  hazardous substances, underground storage tanks and solid waste on
any  premises  in  which  Grantor is conducting a business; provided, however,
Grantor  will be obligated to pay for the cost of any such inspection or audit
no more than one time in any twelve (12) month period unless Lender has reason
to  believe that toxic or hazardous substance or solid wastes have been dumped
or  released  on  any  such  premises.  If Grantor fails to order or obtain an
inspection or audit within ten (10) days after Lender's request, Lender may at
its  option  order  such inspection or audit, and Grantor grants to Lender and
its  agents,  employees, contractors and consultants access to the premises in
which  it  is  conducting its business and a license (which is coupled with an
interest and is irrevocable) to obtain inspections and audits.  Grantor agrees
to  promptly  provide Lender with a copy of the results of any such inspection
or  audit  received  by  Grantor.   The cost of such inspections and audits by
Lender  shall  be  a  part  of the Indebtedness, secured by the Collateral and
payable  by  Grantor  on  demand.

CHATTEL  PAPER.    To  the  extent a security interest in the chattel paper of
Grantor  is  granted  hereunder, Grantor represents and warrants that all such
chattel paper have only one original counterpart and no other party other than
Grantor  or Lender is in actual or constructive possession of any such chattel
paper.    Grantor  agrees  that at the option of and on the request by Lender,
Grantor will either deliver to Lender all originals of the chattel paper which
is  included  in  the  Collateral  or  will mark all such chattel paper with a
legend  indicating that such chattel paper is subject to the security interest
granted  hereunder.

LANDLORD'S  WAIVERS.   Grantor agrees that upon the request of Lender, Grantor
shall  cause  each landlord of real property leased by Grantor at which any of
the  Collateral is located from time to time to execute and deliver agreements
satisfactory  in form and substance to Lender by which such landlord waives or
subordinates  any  rights  it  may  have  in  the  Collateral.


GRANTOR'S  RIGHT  TO  POSSESSION  AND  TO COLLECT ACCOUNTS.  Until default and
except  as otherwise provided below with respect to accounts, Grantor may have
possession  of  the  tangible  personal property and beneficial use of all the
Collateral  and  may  use  it  in any lawful manner not inconsistent with this
Agreement  or  the  Related  Documents,  provided  that  Grantor's  right  to
possession  and  beneficial  use  shall  not  apply  to  any  Collateral where
possession  of the Collateral by Lender is required by law to perfect Lender's
security  interest  in  such  Collateral.  Until otherwise notified by Lender,
Grantor may collect any of the Collateral consisting of accounts.  At any time
and  even  though no Event of Default exists, Lender may collect the accounts,
notify  account debtors to make payments directly to Lender for application to
the Indebtedness and to verify the accounts with such account debtors.  Lender
also  has  the right, at the expense of Grantor, to enforce collection of such
accounts  and  adjust,  settle, compromise, sue for or foreclose on the amount
owing  under  any  such  account, in the same manner and to the same extent as
Grantor.    If  Lender  at  any time has possession of any Collateral, whether
before  or after an Event of Default, Lender shall be deemed to have exercised
reasonable  care  in  the custody and preservation of the Collateral if Lender
takes  such  action for that purpose as Grantor shall request or as Lender, in
Lender's  sole discretion, shall deem appropriate under the circumstances, but
failure  to honor any request by Grantor shall not of itself be deemed to be a
failure to exercise reasonable care.  Lender shall not be required to take any
steps  necessary  to  preserve  any  rights  in  the  Collateral against prior
parties,  nor  to protect, preserve or maintain any security interest given to
secure  the  Indebtedness.

EXPENDITURES  BY  LENDER.  If not discharged or paid when due, Lender may (but
shall  not  be  obligated  to)  discharge  or  pay  any amounts required to be
discharged  or  paid  by  Grantor  under  this  Agreement,  including  without
limitation  all  taxes,  liens,  security  interests,  encumbrances, and other
claims,  at any time levied or placed on the Collateral.  Lender also may (but
shall  not  be  obligated  to)  pay  all  costs  for insuring, maintaining and
preserving  the  Collateral.  All such expenditures incurred or paid by Lender
for  such  purposes will then bear interest at the rate charged under the Note
from  the date incurred or paid by Lender to the date of repayment by Grantor.
All  such  expenses  shall become a part of the Indebtedness and be payable on
demand  by  Lender.    Such right shall be in addition to all other rights and
remedies  to  which  Lender may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT.  Each of the following shall constitute an Event of Default
under  this  Agreement:

DEFAULT  ON  INDEBTEDNESS.  Failure of Grantor to make any payment when due on
the  Indebtedness.

OTHER  DEFAULTS.     Failure of Grantor to comply with or to perform any other

to Lender under this Agreement, the Note or any of the other Related Documents
is  false  or  misleading  in  any  material  respect.

DEFAULT  TO  THIRD  PARTY.    The  occurrence  of  any event which permits the
acceleration  of  the  maturity  of  any  indebtedness owing by Grantor or any
Guarantor  to  any  third  party  under  any  agreement  or  undertaking.

BANKRUPTCY  OR  INSOLVENCY.    If  the  Grantor  or any Guarantor: (i) becomes
insolvent,  or  makes a transfer in fraud of creditors, or makes an assignment
for  the  benefit  of creditors, or admits in writing its inability to pay its
debts as they become due; (ii) generally is not paying its debts as such debts
become  due; (iii) has a receiver, trustee or custodian appointed for, or take
possession  of, all or substantially all of the assets of such party or any of
the  Collateral,  either  in  a  proceeding  brought  by  such  party  or in a
proceeding  brought  against such party and such appointment is not discharged
or  such  possession  is  not  terminated  within  sixty  (60)  days after the
effective  date  thereof  or  such  party  consents  to  or acquiesces in such
appointment  or  possession; (iv) files a petition for relief under the United
States  Bankruptcy  Code  or  any  other  present  or  future federal or state

for relief is filed against such party under any Applicable Bankruptcy Law and
such  Involuntary  petition  is not dismissed within sixty (60) days after the
filing  thereof, or an order for relief naming such party is entered under any

period of sixty (60) days any attachment, sequestration or similar writ levied
upon  any property of such party; or (vi) fails to pay within thirty (30) days

entity  or,  if  any  of  such  parties  is  an individual, the death or legal
incapacity  of  any  such  individual.

CREDITOR OR FORFEITURE PROCEEDINGS.  Commencement of foreclosure or forfeiture
proceedings,  whether  by  judicial proceeding, self-help, repossession or any
other method, by any creditor of Grantor or by any governmental agency against
the  Collateral  or  any  other  collateral  securing  the  Indebtedness.

RIGHTS  AND  REMEDIES  ON  DEFAULT.   If an Event of Default occurs under this
Agreement,  at  any  time  thereafter,  Lender  shall have all the rights of a
secured  party  under the Code. In addition and without limitation, Lender may
exercise  any  one  or  more  of  the  following  rights  and  remedies:

ACCELERATE  INDEBTEDNESS.    Lender  may  declare  the  entire  indebtedness,
including  any  prepayment  penalty  which  Grantor  would be required to pay,
immediately  due  and  payable,  without  notice.


ASSEMBLE  COLLATERAL.   Lender may require Grantor to deliver to Lender all or
any  portion of the Collateral and any and all certificates of title and other
documents  relating to the Collateral.  Lender may require Grantor to assemble
the  Collateral and make it available to Lender at a place to be designated by
Lender.    Lender  also  shall  have  full power to enter upon the property of
Grantor  to  take  possession of and remove the Collateral.  If the Collateral
contains  other  goods  not  covered  by  this  Agreement  at  the  time  of
repossession,  Grantor  agrees Lender may take such other goods, provided that
Lender  makes reasonable efforts to return them to Grantor after repossession.

SELL  THE  COLLATERAL.  Lender shall have full power to sell, lease, transfer,
or otherwise dispose of the Collateral or the proceeds thereof in its own name
or  that of Grantor.  Lender may sell the Collateral (as a unit or in parcels)
at  public  auction  or  private  sale.  Lender may buy the Collateral, or any
portion  thereof,  (i) at any public sale, and (ii) at any private sale if the
Collateral  is  of  a  type customarily sold in a recognized market or is of a
type  which  is  the  subject of widely distributed standard price quotations.
Lender  shall  not be obligated to make any sale of Collateral regardless of a
notice  of  sale  having been given.  Lender may adjourn any public or private
sale  from  time to time by announcement at the time and place fixed therefor,
and  such  sale  may, without further notice, be made at the time and place to
which  it  was so adjourned.  Unless the Collateral is perishable or threatens
to  decline speedily in value or is of a type customarily sold on a recognized
market,  Lender  will  give Grantor reasonable notice of the time and place of
any  public  sale  thereof  or of the time after which any private sale or any
other  intended disposition of the Collateral is to be made.  The requirements
of  reasonable  notice  shall be met if such notice is given at least ten (10)
days  prior to the date any public sale, or after which a private sale, of any
of such Collateral is to be held.  All expenses relating to the disposition of
the  Collateral,  including  without  limitation  the  expenses  of  retaking,
holding, insuring, preparing for sale and selling the Collateral, shall become
a  part  of the Indebtedness secured by this Agreement and shall be payable on
demand,  with interest at the Note rate from date of expenditure until repaid.
Under  all  circumstances, the Indebtedness will be repaid without relief from
any  Indiana  or  other  valuation  and  appraisement  laws.

APPOINT  RECEIVER.    To  the extent permitted by applicable law, Lender shall
have  the  following  rights  and  remedies  regarding  the  appointment  of a
receiver:  (a)  Lender may have a receiver appointed as a matter of right, (b)
the  receiver may be an employee of Lender and may serve without bond, and (c)
all  fees  of  the  receiver  and his or her attorney shall become part of the
Indebtedness  secured  by  this Agreement and shall be payable on demand, with
interest  at  the  Note  rate  from  date  of  expenditure  until  repaid.


COLLECT  REVENUES,  APPLY  ACCOUNTS.    Lender,  either  itself  or  through a
receiver,  may  collect  the  payments,  rents,  income, and revenues from the
Collateral.    Lender may transfer any Collateral into its own name or that of
its  nominee  and  receive the payments, rents, income, and revenues therefrom
and  hold  the same as security for the Indebtedness or apply it to payment of
the Indebtedness in such order of preference as Lender may determine.  Insofar
as  the  Collateral  consists  of  accounts,  general  intangibles,  insurance
policies,  instruments,  chattel paper, choses in action, or similar property,
Lender  may demand, collect, receipt for, settle, compromise, adjust, sue for,
foreclose,  or  realize  on the Collateral as Lender may determine.  For these
purposes,  Lender  may, on behalf of and in the name of Grantor, receive, open
and dispose of mail addressed to Grantor; change any address to which mail and
payments  are  to  be  sent;  and endorse notes, checks, drafts, money orders,
documents  of title, instruments and items pertaining to payment, shipment, or
storage  of  any  Collateral.    To  facilitate  collection, Lender may notify
account  debtors  and  obligors on any Collateral to make payments directly to
Lender.

OBTAIN  DEFICIENCY.    If Lender chooses to sell any or all of the Collateral,
Lender  may  obtain a judgment against Grantor for any deficiency remaining on
the  Indebtedness due to Lender after application of all amounts received from
the  exercise  of  the  rights  provided  in this Agreement.  Grantor shall be
liable  for  a deficiency even if the transaction described in this subsection
is  a  sale  of  accounts  or  chattel  paper.

OTHER RIGHTS AND REMEDIES.  Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Code, as may be amended from time
to  time.    In  addition, Lender shall have and may exercise any or all other
rights  and  remedies  it  may have available at law, in equity, or otherwise.
Grantor waives any right to require Lender to proceed against any third party,
exhaust  any  other security for the Indebtedness or pursue any other right or
remedy  available  to  Lender.

CUMULATIVE  REMEDIES.   All of Lender's rights and remedies, whether evidenced
by  this  Agreement or the Related Documents or by any other writing, shall be
cumulative  and  may  be  exercised  singularly  or concurrently.  Election by
Lender to pursue any remedy shall not exclude pursuit of any other remedy, and
an election to make expenditures or to take action to perform an obligation of
Grantor  under  this  Agreement, after Grantor's failure to perform, shall not
affect  Lender's  right  to  declare  a  default and to exercise its remedies.

MISCELLANEOUS  PROVISIONS.

AMENDMENTS.   This Agreement, together with any Related Documents, constitutes
the  entire  understanding  and agreement of the parties as to the matters set
forth  in  this Agreement and supercedes all prior written and oral agreements
and  understandings, if any, regarding same.  No alteration of or amendment to
this  Agreement  shall  be effective unless given in writing and signed by the
party or parties sought to be charged or bound by the alteration or amendment.

APPLICABLE  LAW.   This Agreement has been delivered to Lender and accepted by
Lender  in  the State of Indiana.  Subject to the provisions on arbitration in
any  Related  Document,  this  Agreement shall be governed by and construed in
accordance  with  the  laws  of  the  State  of  Indiana without regard to any
conflict  of  laws  or  provisions  thereof.


JURY  WAIVER.    THE  UNDERSIGNED AND LENDER (BY ITS ACCEPTANCE HEREOF) HEREBY
VOLUNTARILY,  KNOWINGLY,  IRREVOCABLY  AND  UNCONDITIONALLY WAIVE ANY RIGHT TO
HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED UPON CONTRACT,
TORT  OR OTHERWISE) BETWEEN OR AMONG THE UNDERSIGNED AND LENDER ARISING OUT OF
OR  IN  ANY  WAY RELATED TO THIS DOCUMENT OR ANY OTHER RELATED DOCUMENT.  THIS
PROVISION  IS  A  MATERIAL  INDUCEMENT  TO  LENDER  TO  PROVIDE  THE FINANCING
DESCRIBED  HEREIN  OR  IN  THE  OTHER  RELATED  DOCUMENTS.

ATTORNEYS'  FEES; EXPENSES.  Grantor will upon demand pay to Lender the amount
of  any  and  all costs and expenses (including without limitation, reasonable
attorneys'  fees  and  expenses) which Lender may incur in connection with (i)
the  perfection  and  preservation  of  the collateral assignment and security
interests created under this Agreement, (ii) the custody, preservation, use or
operation  of, or the sale of, collection from, or other realization upon, the
Collateral,  (iii)  the exercise or enforcement of any of the rights of Lender
under this Agreement, or (iv) the failure by Grantor to perform or observe any
of  the  provisions  hereof.

TERMINATION.    Upon  (i) the satisfaction in full of the Indebtedness and all
obligations hereunder, (ii) the termination or expiration of any commitment of
Lender  to  extend  credit that would become Indebtedness hereunder, and (iii)
Lender's receipt of a written request from Grantor for the termination hereof,
this  Agreement  and  the  security  interests created hereby shall terminate.
Upon termination of this Agreement and Grantor's written request, Lender will,
at  Grantor's  sole cost and expense, return to Grantor such of the Collateral
as  shall  not  have been sold or otherwise disposed of or applied pursuant to
the  terms hereof and execute and deliver to Grantor such documents as Grantor
shall  reasonably  request  to  evidence  such  termination.

INDEMNITY.    Grantor  hereby  agrees  to  indemnify, defend and hold harmless
Lender,  and  its  officers,  directors,  shareholders,  employees, agents and
representatives  (each  an  "Indemnified Person") from and against any and all
liabilities,  obligations,  claims,  losses,  damages,  penalties,  actions,
judgments,  suits,  costs,  expenses  or  disbursements  of any kind or nature
(collectively,  the "Claims") which may be imposed on, incurred by or asserted
against,  any  Indemnified  Person  (whether  or not caused by any Indemnified
Person's  sole,  concurrent  or contributory negligence) arising in connection
with  the  Related  Documents,  the Indebtedness or the Collateral (including,
without  limitation,  the enforcement of the Related Documents and the defense
of  any  Indemnified  Person's  action and/or inactions in connection with the
Related  Documents),  except to the limited extent that the Claims against the
Indemnified  Person  are proximately caused by such Indemnified Person's gross
negligence  or  willful  misconduct.  The indemnification provided for in this
Section  shall  survive the termination of this Agreement and shall extend and
continue  to  benefit each individual or entity who is or has at any time been
an  Indemnified  Person  hereunder.

CAPTION  HEADINGS.    Caption  headings  in this Agreement are for convenience
purposes  only and are not to be used to interpret or define the provisions of
this  Agreement.


NOTICES.  All notices required to be given under this Agreement shall be given
in  writing,  and shall be effective when actually delivered or when deposited
with  a  nationally  recognized  overnight  courier or deposited in the United
States  mail, first class, postage prepaid, addressed to the party to whom the
notice  is  to  be given at the address shown above.  Any party may change its
address  for  notices  under this Agreement by giving formal written notice to
the  other parties, specifying that the purpose of the notice is to change the
party's  address.  To the extent permitted by applicable law, if there is more
than  one  Grantor,  notice  to  any  Grantor  will  constitute  notice to all
Grantors.  For notice purposes, Grantor will keep Lender informed at all times
of  Grantor's  current  address(es).

POWER OF ATTORNEY.  Grantor hereby irrevocably appoints Lender as its true and
lawful  attorney-in-fact,  such  power  of  attorney  being  coupled  with  an
interest, with full power of substitution to do the following in the place and
stead  of Grantor and in the name of Grantor: (a) to demand, collect, receive,
receipt for, sue and recover all sums of money or other property which may now
or hereafter become due, owing or payable from the Collateral; (b) to execute,
sign  and endorse any and all claims, instruments, receipts, checks, drafts or
warrants issued in payment for the Collateral; (c) to settle or compromise any
and  all  claims  arising under the Collateral, and, in the place and stead of
Grantor,  to execute and deliver its release and settlement for the claim; and
(d)  to  file  any  claim or claims or to take any action or institute or take
part  in any proceedings, either in its own name or in the name of Grantor, or
otherwise,  which  in  the  discretion  of  Lender may seem to be necessary or
advisable.    This  power  is  given as security for the Indebtedness, and the
authority  hereby  conferred  is  and shall be irrevocable and shall remain in
full  force  and  effect  until  renounced  by  Lender.

SEVERABILITY.    If  a  court of competent jurisdiction finds any provision of
this  Agreement  to  be  invalid  or  unenforceable  as  to  any  person  or
circumstance,  such  finding  shall  not  render  that  provision  invalid  or
unenforceable as to any other persons or circumstances.  If feasible, any such
offending  provision shall be deemed to be modified to be within the limits of
enforceability  or  validity; however, if the offending provision cannot be so
modified,  it  shall be stricken and all other provisions of this Agreement In
all  other  respects  shall  remain  valid  and  enforceable.

SUCCESSOR  INTERESTS.   Subject to the limitations set forth above on transfer
of  the  Collateral,  this  Agreement  shall  be binding upon and inure to the
benefit  of  the  parties,  their  successors  and assigns; provided, however,
Grantor's  rights  and  obligations hereunder may not be assigned or otherwise
transferred  without  the  prior  written  consent  of  Lender.


WAIVER.    Lender  shall  not  be  deemed to have waived any rights under this
Agreement  unless  such  waiver  is given in writing and signed by Lender.  No
delay  or omission on the part of Lender in exercising any right shall operate
as  a  waiver  of  such  right  or  any  other right.  A waiver by Lender of a
provision  of  this  Agreement  shall  not prejudice or constitute a waiver of
Lender's  right  to thereafter demand strict compliance with that provision or
any  other  provision  of  this Agreement.  No prior waiver by Lender, nor any
course of dealing between Lender and Grantor, shall constitute a waiver of any
of  Lender's  rights  or  of  any  of  Grantor's  obligations as to any future
transactions.    Whenever  the  consent  of  Lender  is  required  under  this
Agreement,  the  granting  of such consent by Lender in any instance shall not
constitute  continuing  consent  to subsequent instances where such consent is
required  and in all cases such consent may be granted or withheld in the sole
discretion  of  Lender.

GRANTOR  ACKNOWLEDGES  HAVING  READ  ALL  THE  PROVISIONS  OF  THIS COMMERCIAL
SECURITY  AGREEMENT,  AND GRANTOR AGREES TO ITS TERMS. THIS AGREEMENT IS DATED
MARCH  1,  1998.

JURY  WAIVER.    THE  UNDERSIGNED AND LENDER (BY ITS ACCEPTANCE HEREOF) HEREBY
VOLUNTARILY,  KNOWINGLY,  IRREVOCABLY  AND  UNCONDITIONALLY WAIVE ANY RIGHT TO
HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED UPON CONTRACT,
TORT  OR OTHERWISE) BETWEEN OR AMONG THE UNDERSIGNED AND LENDER ARISING OUT OF
OR  IN  ANY  WAY RELATED TO THIS DOCUMENT OR ANY OTHER RELATED DOCUMENT.  THIS
PROVISION  IS  A  MATERIAL  INDUCEMENT  TO  LENDER  TO  PROVIDE  THE FINANCING
DESCRIBED  HEREIN  OR  IN  THE  OTHER  RELATED  DOCUMENTS.

ARBITRATION.  Lender and Borrower agree that upon the written demand of either
party,  whether made before or after the institution of any legal proceedings,
but  prior  to the rendering of any judgment in that proceeding, all disputes,
claims  and controversies between them, whether individual, joint, or class in
nature,  arising  from  this  Agreement,  any  Related  Document or otherwise,
including  without  limitation  contract  disputes  and  tort claims, shall be
arbitrated  pursuant  to  the  Commercial  Rules  of  the American Arbitration
Association.    Any  arbitration  proceeding held pursuant to this arbitration
provision shall be conducted in the city nearest the Borrower's address having
an  AAA regional office, or at any other place selected by mutual agreement of
the  parties.  No  act to take or dispose of any Collateral shall constitute a
waiver  of  this  arbitration  agreement  or be prohibited by this arbitration
agreement.    This  arbitration  provision shall not limit the right of either
party  during  any  dispute,  claim  or  controversy  to seek, use, and employ
ancillary,  provisional  or  preliminary  rights  and/or remedies, judicial or
otherwise,  for  the  purposes  of  realizing  upon,  preserving,  protecting,
foreclosing  upon  or  proceeding  under  forcible  entry  and  detainer  for
possession of, any real or personal property, and any such action shall not be
deemed  an election of remedies.  This includes, without limitation, obtaining
injunctive  relief  or a temporary restraining order, invoking a power of sale
under  any  deed  of  trust  or  mortgage,  obtaining  a writ of attachment or
imposition  of  a  receivership, or exercising any rights relating to personal
property,  including  taking  or  disposing  of  such property with or without
judicial  process  pursuant  to  Article 9 of the Uniform Commercial Code. Any
disputes, claims, or controversies concerning the lawfulness or reasonableness
of  any  act,  or  exercise of any right or remedy, concerning any Collateral,
including  any  claim  to  rescind,  reform, or otherwise modify any agreement
relating to the Collateral, shall also be arbitrated; provided however that no
arbitrator  shall have the right or the power to enjoin or restrain any act of
either  party.  Judgment  upon  any  award  rendered  by any arbitrator may be
entered  in  any  court  having  jurisdiction.    Nothing  in this arbitration
provision  shall  preclude  either  party from seeking equitable relief from a
court  of  competent  jurisdiction.    The  statute  of limitations, estoppel,
waiver, laches and similar doctrines which would otherwise be applicable in an
action  brought  by a party shall be applicable in any arbitration proceeding,
and  the  commencement  of  an  arbitration  proceeding  shall  be  deemed the
commencement  of  any  action  for these purpose.  The Federal Arbitration Act
(Title  9  of  the  United  States  Code)  shall  apply  to  the construction,
interpretation,  and  enforcement  of  this  arbitration  provision.


SEVERABILITY.    If  a  court of competent jurisdiction finds any provision of
this  Agreement  to  be  invalid  or  unenforceable  as  to  any  person  or
circumstance,  such  finding  shall  not  render  that  provision  invalid  or
unenforceable as to any other persons or circumstances.  If feasible, any such
offending  provision shall be deemed to be modified to be within the limits of
enforceability  or  validity; however, if the offending provision cannot be so
modified,  it  shall be stricken and all other provisions of this Agreement in
all  other  respects  shall  remain  valid  and  enforceable.

WAIVER.    Lender  shall  not  be  deemed to have waived any rights under this
Agreement  unless  such  waiver  is given in writing and signed by Lender.  No
delay  or omission on the part of Lender in exercising any right shall operate
as  a  waiver  of  such  right  or  any  other right.  A waiver by Lender of a
provision  of  this  Agreement  shall  not prejudice or constitute a waiver of
Lender's  right  otherwise  to demand strict compliance with that provision or
any  other  provision  of  this Agreement.  No prior waiver by Lender, nor any
course  of  dealing  between Lender and Borrower, shall constitute a waiver of
any  of  Lender's  rights  or  of any obligations of Borrower as to any future
transactions.    Whenever  the  consent  of  Lender  is  required  under  this
Agreement,  the  granting  of such consent by Lender in any instance shall not
constitute  continuing  consent  in subsequent instances where such consent is
required, and in all cases such consent may be granted or withheld in the sole
and  absolute  discretion  of  Lender.

BORROWER  ACKNOWLEDGES  HAVING READ ALL THE PROVISIONS OF THIS NEGATIVE PLEDGE
AGREEMENT,  AND  BORROWER  AGREES TO ITS TERMS.  THIS AGREEMENT IS DATED AS OF

the  same  day  of each month thereafter during the term of this Note, and the
outstanding  principal  balance  of  this  Note, together with all accrued but
unpaid  interest,  shall  be  due  and  payable  on March 1, 1999.  The annual
interest  rate  for  this  Note  is  computed  on a 365-360 basis; that is, by
applying  the  ratio  of  the  annual  interest  rate over a year of 360 days,
multiplied  by  the  outstanding  principal  balance, multiplied by the actual
number of days the principal balance is outstanding.  Borrower will pay Lender
at  the  address  designated  by  Lender from time to time in writing.  If any
payment  of  principal  of  or interest on this Note shall become due on a day
which is not a Business Day, such payment shall be made on the next succeeding
Business  Day.    As  used  herein, the term "Business Day" shall mean any day
other  than  a  Saturday,  Sunday  or  any other day on which national banking
associations  are  authorized  to  be  closed.  Unless otherwise agreed to, in
writing,  or  otherwise  required  by applicable law, payments will be applied
first to accrued, unpaid interest, then to principal, and any remaining amount
to  any  unpaid  collection  costs,  late charges and other charges, provided,
however, upon delinquency or other default, Lender reserves the right to apply
payments  among  principal, interest, late charges, collection costs and other
charges  at  its  discretion.   The books and records of Lender shall be prima
facie evidence of all outstanding principal of and accrued but unpaid interest
on this Note.  If this Note is governed by or is executed in connection with a
loan  agreement,  this  Note  is  subject to the terms and provisions thereof.

VARIABLE  INTEREST  RATE.    The  interest  rate  on  this  Note is subject to
fluctuation  based upon the Prime Rate of interest in effect from time to time
(the  "Index")  (which rate may not be the lowest, best or most favorable rate
of  interest which Lender may charge on loans to its customers).  "Prime Rate"
shall  mean  the rate announced from time to time by Lender as its prime rate.
Each  change  in  the  rate  to  be charged on this Note will become effective
without  notice  on  the  same  day as the Index changes.  Except as otherwise
provided  herein,  the  unpaid  principal  balance  of  this  Note will accrue
interest  at a rate per annum which will from time to time be equal to the sum
of  the Index, plus 0.000%.  NOTICE:  Under no circumstances will the interest
rate  on  this  Note  be more than the maximum rate allowed by applicable law.

PREPAYMENT.    Borrower  may pay without fee all or a portion of the principal
amount  owed  hereunder  earlier  than  it  is  due.  All prepayments shall be
applied to the indebtedness owing hereunder in such order and manner as Lender
may  from  time  to  time  determine  in  its  sole  discretion.

LATE  CHARGE.   If a payment is 10 days or more late, Borrower will be charged
5.000%  of the regularly scheduled payment or $25.00, whichever is greater, up
to  the  maximum  amount  of  $250.00  per  late  charge.

DEFAULT.    Borrower  will  be in default if any of the following happens: (a)
Borrower  fails  to  make  any payment of principal or interest when due under
this  Note  or  any  other  indebtedness owing now or hereafter by Borrower to
Lender;  (b)  failure of Borrower or any other party to comply with or perform
any  term,  obligation, covenant or condition contained in this Note or in any
other  promissory  note,  credit agreement, loan agreement, guaranty, security
agreement,  mortgage,  deed  of  trust  or  any other instrument, agreement or
document,  whether now or hereafter existing, executed in connection with this
Note (the Note and all such other instruments, agreements, and documents shall
be  collectively  known  herein  as  the  "Related  Documents");  (c)  Any
representation  or statement made or furnished to Lender herein, in any of the
Related  Documents  or  in  connection  with  any of the foregoing is false or
misleading in any material respect; (d) Borrower or any other party liable for
the  payment  of  this  Note, whether as maker, endorser, guarantor, surety or
otherwise,  becomes insolvent or bankrupt, has a receiver or trustee appointed
for  any  part  of  its  property,  makes an assignment for the benefit of its
creditors,  or any proceeding is commenced either by any such party or against
it under any bankruptcy or insolvency laws; (e) the occurrence of any event of
default  specified  in  any  of  the  other  Related Documents or in any other
agreement  now  or  hereafter  arising  between  Borrower  and Lender; (f) the
occurrence  of any event which permits the acceleration of the maturity of any
indebtedness owing now or hereafter by Borrower to any third party; or (g) the
liquidation,  termination,  dissolution, death or legal incapacity of Borrower
or  any  other  party  liable  for the payment of this Note, whether as maker,
endorser,  guarantor,  surety,  or  otherwise.

LENDER'S  RIGHTS.    Upon  default,  Lender may at its option, without further
notice  or demand (i) declare the entire unpaid principal balance on this Note
and  all  accrued  unpaid interest immediately due, (ii) refuse to advance any
additional amounts under this Note, (iii) foreclose all liens securing payment
hereof,  (iv) pursue any other rights, remedies and recourses available to the
Lender,  including  without limitation, any such rights, remedies or recourses
under  the  Related  Documents,  at  law  or  in  equity,  or  (v)  pursue any
combination  of  the foregoing.  Upon default resulting from the bankruptcy or
insolvency  of the Borrower as described in clause (e) above under the heading
"DEFAULTS",  the  unpaid  principal  balance  of this Note and all accrued but
unpaid interest thereon shall automatically become due and payable immediately
and shall not be subject to the discretion of Lender.  Upon default, including
failure  to pay upon final maturity, Lender, at its option, may also do one or
both of the following: (a) increase the variable interest rate on this Note to
3.000  percentage  points  over  the  Index,  and  (b)  add any unpaid accrued
interest  to principal and such sum will bear interest therefrom until paid at
the  rate  provided in this Note (including any increased rate).  The interest
rate will not exceed the maximum rate permitted by applicable law.  Lender may
hire  an  attorney  to  help  collect  this  Note if Borrower does not pay and
Borrower  will  pay Lender's reasonable attorneys' fees and all other costs of
collection,  unless  prohibited  by  applicable law.  This Note will be repaid
under all circumstances without relief from any Indiana or other valuation and
appraisement  laws.    This  Note has been delivered to Lender and accepted by
Lender  in  the  State  of Indiana.  Subject to the provisions on arbitration,
this  Note  shall  be governed by and construed in accordance with the laws of
the  State  of  Indiana  without  regard to any conflict of laws or provisions
thereof.

PURPOSE.    Borrower agrees that no advances under this Note shall be used for
personal,  family, or household purposes and that all advances hereunder shall
be  used  solely  for  business,  commercial,  agricultural  or  other similar
purposes.

JURY  WAIVER.    THE  BORROWER  AND  LENDER  (BY ITS ACCEPTANCE HEREOF) HEREBY
VOLUNTARILY,  KNOWINGLY,  IRREVOCABLY  AND  UNCONDITIONALLY WAIVE ANY RIGHT TO
HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE (WHETHER BASED UPON CONTRACT,
TORT  OR  OTHERWISE)  BETWEEN BORROWER AND LENDER ARISING OUT OF OR IN ANY WAY
RELATED  TO  THIS  NOTE  OR  THE OTHER RELATED DOCUMENTS.  THIS PROVISION IS A
MATERIAL INDUCEMENT TO LENDER TO PROVIDE THE FINANCING EVIDENCED BY THIS NOTE.

DISHONORED  ITEM FEE.  Borrower will pay a fee to Lender of $20.00 if Borrower
makes  a payment on Borrower's loan and the check or preauthorized charge with
which  Borrower  pays  is  later  dishonored.

RIGHT  OF  SETOFF.  Unless a lien would be prohibited by law or would render a
nontaxable account taxable, Borrower grants to Lender a contractual possessory
security  interest  in,  and  hereby  assigns, conveys, delivers, pledges, and
transfers  to  Lender  all  Borrower's  right,  title  and interest in and to,
Borrower's  accounts  with  Lender  (whether  checking,  savings, or any other
account),  including without limitation all accounts held jointly with someone
else  and  all  accounts Borrower may open in the future.  Borrower authorizes
Lender,  to  the  extent  permitted by applicable law, to charge or setoff all
sums  owing  on  this  Note  against  any  and  all  such  accounts.

LINE OF CREDIT.  This Note evidences a revolving line of credit.  Borrower may
request  advances and make payments hereunder from time to time, provided that
it  is  understood  and agreed that the aggregate principal amount outstanding
from  time  to time hereunder shall not at any time exceed the Total Principal
Amount.  The unpaid principal balance of this Note shall increase and decrease
with  each  new  advance or payment hereunder, as the case may be.  Subject to
the terms hereof, Borrower may borrow, repay and reborrow hereunder.  Advances
under  this  Note, as well as directions for payment from Borrower's accounts,
may  be requested orally or in writing by Borrower or by an authorized person.
Lender  may,  but  need  not,  require  that all oral requests be confirmed in
writing.    Borrower  agrees to be liable for all sums either: (a) advanced in
accordance  with  the  instructions of an authorized person or (b) credited to
any  of  Borrower's  accounts  with  Lender.

ARBITRATION.  Lender and Borrower agree that upon the written demand of either
party,  whether made before or after the institution of any legal proceedings,
but  prior  to the rendering of any judgment in that proceeding, all disputes,
claims  and controversies between them, whether individual, joint, or class in
nature,  arising  from this Note, any Related Document or otherwise, including
without  limitation  contract  disputes  and  tort claims, shall be arbitrated
pursuant to the Commercial Rules of the American Arbitration Association.  Any
arbitration  proceeding  held  pursuant to this arbitration provision shall be
conducted  in  the  city nearest the Borrower's address having an AAA regional
office, or at any other place selected by mutual agreement of the parties.  No
act  to  take  or  dispose of any collateral shall constitute a waiver of this
arbitration  agreement  or  be prohibited by this arbitration agreement.  This
arbitration  provision  shall  not  limit the right of either party during any
dispute,  claim or controversy to seek, use, and employ ancillary, provisional
or preliminary rights and/or remedies, judicial or otherwise, for the purposes
of  realizing  upon,  preserving,  protecting,  foreclosing upon or proceeding
under  forcible  entry  and  detainer  for possession of, any real or personal
property,  and  any  such  action shall not be deemed an election of remedies.
This  includes, without limitation, obtaining injunctive relief or a temporary
restraining  order,  invoking  a  power  of  sale  under  any deed of trust or
mortgage,  obtaining  a writ of attachment or imposition of a receivership, or
exercising  any  rights  relating  to  personal  property, including taking or
disposing  of  such  property  with  or  without  judicial process pursuant to
Article  9  of  the  Uniform  Commercial  Code.    Any  disputes,  claims,  or
controversies  concerning  the  awfulness  or  reasonableness  of  any act, or
exercise  of  any  right  or  remedy, concerning any collateral, including any
claim  to  rescind,  reform, or otherwise modify any agreement relating to the
collateral,  shall  also  be  arbitrated;  provided however that no arbitrator
shall  have  the  right  or  the power to enjoin or restrain any act of either
party.    Judgment upon any award rendered by any arbitrator may be entered in
any  court  having  jurisdiction.  Nothing in this arbitration provision shall
preclude  either party from seeking equitable relief from a court of competent
jurisdiction.    The  statute  of  limitations,  estoppel,  waiver, laches and
similar  doctrines which would otherwise be applicable in an action brought by
a  party  shall  be  applicable  in  any  arbitration  proceeding,  and  the
commencement  of an arbitration proceeding shall be deemed the commencement of
any  action  for  these  purpose.  The Federal Arbitration Act (Title 9 of the
United  States  Code)  shall  apply  to  the construction, interpretation, and
enforcement  of  this  arbitration  provision.

RENEWAL  AND  EXTENSION.    This  Note is given in replacement, renewal and/or
extension  of,  but  not  extinguishing  the  indebtedness  evidenced by, that
promissory  note  dated  May  9,  1997  executed  by  Borrower in the original
principal amount of 2,200,000.00, and is not a novation thereof.  All interest
evidenced  by  the  note  being  replaced,  renewed,  and/or  extended by this
instrument  shall  continue  to  be  due  and  payable  until  paid.

GENERAL  PROVISIONS.  Lender may delay or forgo enforcing any of its rights or
remedies  under  this Note without losing them.  Borrower and any other person
who  signs,  guarantees  or  endorses this Note, to the extent allowed by law,
waive  presentment,  demand for payment, protest and notice of dishonor.  Upon
any change in the terms of this Note, end unless otherwise expressly stated in
writing,  no  party  who  signs  this  Note,  whether  as  maker,  guarantor,
accommodation  maker  or endorser, shall be released from liability.  All such
parties  agree  that Lender may renew or extend (repeatedly and for any length
of  time)  this  Note,  or  release  any  party or guarantor or collateral; or
impair,  fail  to  realize  upon  or perfect Lender's security interest in the
collateral;  and  take any other action deemed necessary by Lender without the
consent  of  or notice to anyone.  All such parties also agree that Lender may
modify  this  Note  without  the consent of or notice to anyone other than the
party  with  whom  the  modification  is  made.

PRIOR TO SIGNING THIS NOTE, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS OF
THIS  NOTE,  INCLUDING THE VARIABLE INTEREST RATE PROVISIONS.  BORROWER AGREES
TO  THE  TERMS OF THE NOTE AND ACKNOWLEDGES RECEIPT OF A COMPLETED COPY OF THE
NOTE.
