             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Note 1. Basis of Presentation 
The accompanying  unaudited consolidated financial statements have been prepared
in  accordance  with  generally  accepted  accounting   principles  for  interim
financial  information and in accordance  with the  instructions to Form 10-QSB.
Accordingly,  they do not include all of the financial information and footnotes
required by generally  accepted  accounting  principles  for complete  financial
statements.  In the opinion of management,  all  adjustments  (including  normal
recurring  adjustments)  considered  necessary for a fair presentation have been
included.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial  statements and accompanying notes.
Actual results could differ from those estimates.

The results of operations for the respective interim periods are not necessarily
indicative  of the results to be expected  for the full year.  The  accompanying
unaudited  consolidated  financial statements should be read in conjunction with
the audited consolidated  financial statements and the notes thereto included in
the  Company's Form 10-KSB for the year ended  December 31, 1998 filed with the
Securities and Exchange Commission.

Note 2. Net Loss Per Common Share
Effective for the year ended December 31, 1997, the Company adopted Statement of
Financial  Accounting  Standards No. 128, "Earnings Per Share" ("SFAS 128"). The
Company's basic and diluted  earnings per share are equal,  due to the exclusion
of  common  stock   equivalents,   which  would  make  the  earnings  per  share
calculations anti-dilutive.

Note 3.  Inventories
Inventories consist of the following:
                                        March 31, 1999

Note 4. Long-Term Debt

Effective  March 31, 1999, the Company  entered into two debt  agreements with a
bank: a $2,000,000  revolving  line of credit  ("revolver")  and a $500,000 term
note.

                                       6
<PAGE>

The  proceeds  of the  revolver,  when drawn down are  intended  to fund  future
working capital needs.  Borrowings bear interest at either the bank's Prime Rate
plus 1/2% or LIBOR plus 3%. A facility  fee is payable  quarterly on the average
unused commitment at a rate of 3/4%.

The  purpose of the term note is to fund the  purchase  of 7,500  square feet of
manufacturing  and  warehouse  space at the  Company's  ProCath  subsidiary  and
building  improvements.  Interest is payable  monthly in arrears at either Prime
plus 3/4% or LIBOR plus 3 1/4%.  Principal is payable commencing January 2000 in
48 equal  monthly  installments  under a 15 year  amortization  schedule  with a
balloon payment due in December 2004.

The Company is required to maintain certain financial  ratios,  and meet certain
net worth and indebtedness tests. The debt is collateralized by a first priority
lien on all  corporate  assets.  The agreement  also  prohibits the Company from
incurring certain additional indebtedness, limits investments, advances or loans
and restricts substantial asset sales, capital expenditures and cash dividends.

Item 2. Management's Discussion and Analysis or Plan of Operation

Overview
 
The Company was  incorporated  in New Jersey in January  1993 and  operates in a
single industry segment. The Company develops, manufactures, markets and sells a
line of  products  for  the  cardiac  electrophysiology  ("EP")  market  used to
diagnose,  monitor and treat irregular  heartbeats  known as arrhythmias.  Since
inception,  the Company has acquired technology,  has developed new products and
has  begun  marketing  various  electrophysiology  products,  including  the  EP
WorkMate[REGISTERED]    electrophysiology   workstation,   the   EP-3[TRADEMARK]
Stimulator,   diagnostic  electrophysiology  catheters,  internal  cardioversion
catheters and related disposable supplies.

The Company has  developed a new product for  internal  cardioversion  of atrial
fibrillation  known  as the  ALERT[REGISTERED]  System,  which  uses a  patented
electrode catheter to deliver measured, variable, low energy electrical impulses
directly to the inside of the heart in order to convert atrial fibrillation to a
normal heart rhythm.  The  ALERT[REGISTERED]  System is not approved for sale in
the United States,  but is currently  undergoing  clinical  trials.  The Company
intends to market a full family of internal  cardioversion  catheters around the
ALERT[REGISTERED] platform.

The Company has also developed an intracardiac ultrasound product line including
the   ViewMate[TRADEMARK]   ultrasound  imaging  console  and  U-View[TRADEMARK]
deflectable  intracardiac  imaging  catheter.  These  products  are  designed to
improve a  physician's  ability to  visualize  inside the chambers of the heart,
including  the  internal  anatomy of the heart.  The Company  believes  that the
ViewMate[TRADEMARK]  and U-View[TRADEMARK] may play an important role as new and
effective  treatment  options are developed for the treatment of complex cardiac
arrhythmias,  including ventricular tachyarrhythmia and atrial fibrillation. The



                                       7
<PAGE>

Company's ultrasound products are not approved for sale and the Company does not
anticipate   receiving   approval   to   sell   the    ViewMate[TRADEMARK]    or
U-View[TRADEMARK] for at least several months, if approved at all.

Forward-Looking Statements
This report contains certain statements of a forward-looking  nature relating to
such matters as  anticipated  financial and  operational  performance,  business
prospects, technological developments, results of clinical trials, new products,
research  and  development  activities  and similar  matters.  Stockholders  are
cautioned that such  statements are only  predictions  and that actual events or
results  may differ  materially.  In  evaluating  such  statements,  prospective
investors  should  specifically  consider  the  various  factors  effecting  the
industry and economy  generally,  as well as those identified in this report and
in  the  Company's   other  reports  filed  with  the  Securities  and  Exchange
Commission,  which could cause actual  results to differ  materially  from those
indicated by such forward-looking statements.

RESULTS OF OPERATIONS

Three months ended March 31, 1999 compared to three months ended March 31, 1998

Sales increased  $1,080,000 (or 74%) in the three months ended March 31, 1999 as
compared to the prior period in 1998. The majority of the increase in revenue in
the quarter resulted from increased sales of the EP  WorkMate[REGISTERED], which
represented a substantial  percentage of sales during the three-month  period in
1999.  The Company  also  realized  increased  sales of certain of its  catheter
products during the period.

The level of sales for the remaining nine months of 1999 will depend  materially
on sales of the EP WorkMate[REGISTERED] and diagnostic catheters and the ability
of the  Company's  direct sales force and network of  international  independent
distributors to effectively market and sell the Company's existing products. The
ALERT[REGISTERED]  System is  currently  undergoing  clinical  trials and is not
approved for sale in the United States.  The  ALERT[REGISTERED]  System has been
introduced for sale in Europe.  However, the Company cannot accurately determine
the sales level of the  ALERT[REGISTERED]  System for the remaining  quarters in
1999 at this time or when it will be available at all in the United States.  The
Company expects the ALERT[REGISTERED]  System to contribute a greater proportion
of revenues in the second half of 1999 and beyond.

Cost of products  sold  increased  $306,000  (or 35%) due to the 74% increase in
sales for the three  months  ended March 31,  1999 as  compared  to 1998.  Gross
profit on sales for the three months ended March 31, 1999 was $1,341,000 (or 53%
as a percentage of sales),  as compared with $568,000 (or 39% as a percentage of
product  sales) for the  comparable  period in 1998.  The  Company  realized  an
increase in gross profit on sales of existing products during first quarter 1999
primarily due to increased sales of the EP WorkMate,  which  currently  yields a
higher gross margin than certain of the Company's  other  products.  The Company


                                       8
<PAGE>

hopes  to  improve  its  overall  gross  profit   percentage  as  sales  of  the
ALERT[REGISTERED]  System and other catheter products increase, which may offset
the fixed costs associated with maintaining a catheter manufacturing operation.

Sales and marketing  expenses  increased  $371,000 (or 53%),  but decreased as a
percentage  of revenue  from  product  sales from 48% to 42% in the three months
ended  March 31,  1999 as compared to 1998.  The dollar  increase  during  first
quarter 1999 was  primarily  due to the impact of expanding  the domestic  sales
force from 6 employees  as of March 31, 1998 to 9 employees as of March 31, 1999
and the increase in travel,  trade show related expenses,  product promotion and
physician   educational   materials  in  support  of  its  sales  efforts.   The
international  distribution  network is currently  supported by a team of direct
international  sales and marketing  professionals,  international field clinical
engineers and administrative support personnel.

General and administrative  expenses increased $249,000 (or 72%) and remained at
24% of sales  revenue in the three  months  ended  March 31, 1999 as compared to
1998.  The increase  during first  quarter 1999 was due to increased  personnel,
occupancy  and other  administrative  costs  necessary to support the  increased
operations. It is anticipated that these expenses may decline as a percentage of
revenues as incremental sales are generated.

Research and development expenses increased $95,000 (or 27%)%), but decreased as
a percentage  of revenue from product  sales from 23% to 18% in the three months
ended March 31, 1999 as compared to 1998.  in the three  months  ended March 31,
1999 as compared to 1998.  During the three  months  ended March 31,  1999,  the
Company  incurred  research and development  expenses in connection with ongoing
development efforts on existing products, including the EP WorkMate[REGISTERED],
costs  associated  with the clinical  trials for the  ALERT[REGISTERED]  System,
development  costs and costs of  preparing  regulatory  submissions  for the new
ultrasound  imaging  product line, as well as costs  associated with several new
products under  development.  The Company  expects that research and development
expenses  are  likely to  increase  in future  periods,  in part due to  ongoing
expenses related to the  ALERT[REGISTERED]  System clinical trials,  new product
development activities and regulatory  applications aimed at gaining approval to
sell other new products.

The net loss for the three  months ended March 31, 1999 was $744,000 as compared
to a net loss of $795,000  during the  comparable  period in first quarter 1998.
The basic and diluted  loss per share for the three  months ended March 31, 1999
was $0.08 per share as compared to $.10 in first quarter 1998.

Liquidity and Capital Resources

Since inception, the Company's expenses have exceeded its sales, resulting in an
accumulated deficit of approximately $15,179,000 at March 31, 1999.

The Company  entered  into two  financing  arrangements  in March of 1999 with a
bank: a $2,000,000 revolving line of credit and a $500,000 term loan. Management
believes  that its current  liquidity  position  will be  sufficient to meet the


                                       9
<PAGE>

needs of the Company  until at least March 31, 2000. In the event that it cannot
generate  additional capital funds during 1999, the Company believes that it can
reduce  non-core  related  expenditures,  which will allow it to continue in its
operations for a significant period.

Net cash used in operating  activities for the three months ended March 31, 1999
decreased  $377,000  (or  38%)  as  compared  to  1998.  The  net use of cash in
operations  during first quarter 1999 was  primarily  due to the Company's  loss
from  operations.  Payables  to related  parties  increased  $257,000  due to an
increase in purchases of components for the Alert[REGISTERED]  System.  Payments
to  related  parties  are made on  terms  similar  to those of other  suppliers.
Accrued expenses payable decreased by $150,000.

Capital  expenditures,  were  $535,000  during first quarter 1999 as compared to
$59,000 in first quarter 1998.  During  February 1999, the Company  purchased an
additional 7,500 square feet of manufacturing and warehouse space at ProCath for
a purchase  price of  approximately  $400,000.  Costs to  prepare  the space for
intended  use are  estimated to be  $100,000.  This  purchase was financed via a
$500,000  term loan  executed  subsequent  to December  31,  1998.  The purchase
provided  for  expansion of the existing  manufacturing  operations,  additional
warehousing,  shipping  and  quality  assurance  activities  and  relocation  of
ProCath's administrative offices.

Net  borrowings  under note  payable  increased  $508,000  as  compared to first
quarter  1998 due to the proceeds the Company  received  from the $500,000  term
loan.

As of the date of this  Report on Form  10-QSB,  the  Company  does not have any
other  material  commitments  for  capital  expenditures.  However,  the Company
expects  to  purchase  capital  equipment  and to expand its  manufacturing  and
assembly  capabilities  as it continues to grow.  The Company  leases office and
manufacturing space and certain office equipment under operating leases.

During  February  1997,  the Company  licensed the rights to several  ultrasound
technologies  from  EchoCath,  for use in the  field of  electrophysiology.  The
agreement with EchoCath calls for the Company to make payments  totaling up to a
maximum of $700,000, in four installments, as certain development milestones and
initial sales are achieved on the EchoMark and EchoEye technologies.  One of the
milestones  calls  for a  $400,000  payment  payable  upon the  completion  of a
development  program for the  EchoEye.  This  milestone  was only payable in the
event that the  development  was completed by September 30, 1998. To the best of
the  Company's  knowledge,  the  milestone  was not  achieved  and no  milestone
payments are accrued or payable to EchoCath as of March 31, 1999.

The Company  expects its  operating  losses to continue in the near future as it
will continue to expend substantial funds for research and development, clinical
trials in support of regulatory approvals,  increased manufacturing capacity and
expansion  of sales and  marketing  activities.  The amount and timing of future
losses will be  dependent  upon,  among  other  things,  increased  sales of the
Company's  existing  products,  clinical  approval and market  acceptance of the
ALERT[REGISTERED] System and developmental, regulatory and market success of new


                                       10
<PAGE>

products under development.  There can be no assurance that any of the Company's
development  projects will be successful or that if  development  is successful,
that the  products  will  generate any sales.  Based upon its current  plans and
projections,  the Company believes that its existing  capital  resources will be
sufficient  to meet its  anticipated  capital needs for at least the next twelve
months.

Year 2000 Readiness

The Year 2000 issue could affect  computers,  software and other equipment used,
operated or maintained by the Company. The Company has substantially completed a
review of its internal computer programs and systems to ensure that the programs
and systems will be Year 2000 compliant.  The Company  presently  believes that,
based on current  plans and efforts to date,  its internal  programs and systems
will be Year 2000 compliant in a timely manner.

The Year 2000 issue can also affect  products sold by the Company,  particularly
the EP  WorkMate[REGISTERED]  and ALERT[REGISTERED]  Companion.  The Company has
performed  an  assessment  of its  products  and,  as a result  of this  review,
believes that it has  substantially  identified  and resolved the potential Year
2000 issues with these products.  However,  the Company also believes that it is
not  possible to determine  with  complete  certainty  that all Year 2000 issues
affecting  the Company's  products have been  identified or corrected due to the
complexity  of these  products and the fact that these  products  interact  with
other third party  products or operate on computer  systems  which are not under
the Company's control.

The Company  believes  that its greatest  Year 2000 risk for  disruption  to its
business is the potential  noncompliance of third parties.  In this regard,  the
Company has  initiated  communications  with its vendors,  major  customers  and
service  providers  in order to  determine  the  extent to which  the  Company's
business is vulnerable to the third parties'  failure to make their systems Year
2000 compliant. Since the Company has no control over the actions of these third
parties,  there can be no assurance that these third parties will resolve any or
all Year 2000  issues.  Any failure of these third  parties to resolve Year 2000
issues in a timely manner could have a material  adverse effect on the Company's
financial condition and results of operations.

The  Company  currently  does  not have a  contingency  plan in the  event  that
particular  systems,  including the systems of material third  parties,  are not
Year 2000  compliant.  It is intended  that such a plan will be  developed if it
becomes clear that the Company is not going to achieve its scheduled  compliance
objectives.   Although  no  assurance  can  be  given  that  there  will  be  no
interruption  of  operations  as a result of the Year 2000  issue,  the  Company
believes  and  assuming  that third  parties  with whom the Company has material
business  relationships  successfully remediate their own Year 2000 issues) that
it has reasonably  assessed its systems in order to ensure that the Company will
not suffer any  material  adverse  effect from the Year 2000  issue.  Though the
Company has used and will continue to use internal resources to resolve its Year
2000 issues,  the Company may retain third party  consultants  to assist in this
regard.

                                       11
<PAGE>

Costs  specifically  associated  with  Year  2000  compliance  are  expensed  as
incurred.  To date, the Company has not spent a material amount on this project.
The Company does not expect the total costs relating to Year 2000  compliance to
have a material  effect on the  Company's  results of  operations  or  financial
condition.  However,  the total costs that the Company will incur in  connection
with the Year 2000 issue will be influenced  by (i) its ability to  successfully
identify Year 2000 issues, (ii) the nature and amount of programming required to
remediate the issues,  (iii) the related labor and/or  consulting costs for such
remediation  and (iv) the  ability of third  parties  with whom the  Company has
business  relationships  to  successfully  address their own Year 2000 concerns.
These and other  unforeseen  factors could have a material adverse effect on the
Company's results of operations or financial condition.




PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

During October 1997, the Company filed a lawsuit against  EchoCath in the United
States  District  Court for the  District  of New Jersey  alleging,  among other
things,  that  EchoCath  made  fraudulent  misrepresentations  and  omissions in
connection  with the prior  sale of  $1,400,000  of its  preferred  stock to the
Company.

EchoCath filed an answer to the complaint, denying the allegations and asserting
a counterclaim against the Company seeking its costs and expenses in the action.
EchoCath also filed a motion to dismiss the complaint.  During October 1998, the
complaint  was  dismissed by the District  Court.  The Company is appealing  the
decision.  The Company  believes that  EchoCath's  counterclaim  and request for
reimbursement  of its costs and  expenses  is without  merit.  As a result,  the
Company has not accrued for such costs and  expenses at March 31,  1999.  In the
opinion of management, the ultimate resolution of the counterclaim will not have
a material  adverse  impact of the Company's  financial  condition or results of
operations.  The Company cannot determine the outcome of the EchoCath litigation
at this time.

to the  first  to  occur  of (i)  the  Expiration  Date,  or  (ii)  the  earlier
termination of the within-described revolving financing arrangements pursuant to
[SECTION]5.2  or  [SECTION]6.7;   provided,  however,  that  (1)  the  aggregate
principal  amount of  Revolving  Loans  outstanding  shall at no time exceed the
Maximum Revolving Amount  (hereinafter  defined) and (2) the Aggregate Revolving
Bank  Liabilities  (hereinafter  defined)  shall at no time exceed the Borrowing
Base  (hereinafter  defined).  Within such limits,  and subject to the terms and
conditions  hereof,  the Borrower may obtain  Revolving  Loans,  repay Revolving
Loans and obtain  Revolving Loans again on one or more occasions.  The Revolving



      
<PAGE>

Loans shall be evidenced by the  Revolving  Note and interest  thereon  shall be
payable at the times and at the rate provided for in the Revolving Note. Overdue
principal of the Revolving  Loans and, to the extent  permitted by law,  overdue
interest shall bear interest at a fluctuating  rate per annum which at all times
shall be equal to the sum of (i) four (4%)  percent  per annum plus (ii) the per
annum rate otherwise payable under the Revolving Note (but in no event in excess
of the  maximum  rate  from  time to time  permitted  by then  applicable  law),
compounded  monthly  and  payable on demand.  The  Borrower  hereby  irrevocably
authorizes  the Bank to make or cause to be made, on a schedule  attached to the
Revolving  Note or on the books of the Bank,  at or following the time of making
each  Revolving  Loan and of receiving any payment of principal,  an appropriate
notation  reflecting such  transaction and the then aggregate  unpaid  principal
balance of the Revolving Loans. The amount so noted shall constitute presumptive
evidence as to the amount owed by the Borrower  with respect to principal of the
Revolving  Loans.  Failure  of the  Bank to make any such  notation  shall  not,
however,  affect  any  obligation  of the  Borrower  or any  right  of the  Bank
hereunder or under the Revolving Note.

     1.3  Repayment;  Renewal of Revolving  Loan  Facility.  The Borrower  shall
repay in full all  Revolving  Loans and all  interest  thereon upon the first to
occur of: (i) the Expiration Date, or (ii) an acceleration under [SECTION]5.2(a)
following  an Event of  Default.  The  Borrower  may repay at any time,  without
penalty or premium, the whole or any portion of any Revolving Loan. In addition,
if at any time the  Borrowing  Base is in an amount  which is less than the then
outstanding  Aggregate  Revolving Bank Liabilities,  the Borrower will forthwith
prepay  so much of the  Revolving  Loans  as may be  required  (or  arrange  for
termination  of such letters of credit as may be required) so that the Aggregate
Revolving Bank  Liabilities will not exceed the Borrowing Base. The Bank may, at
its sole discretion,  renew the revolving  financing  arrangements  described in
this Letter  Agreement by extending the  Expiration  Date in a writing signed by
the Bank and  accepted by the  Borrower.  Neither the  inclusion  in this Letter
Agreement  or  elsewhere  of  covenants  relating  to  periods of time after the
Expiration  Date,  nor any other  provision  hereof,  nor any  action  (except a
written extension pursuant to the immediately preceding sentence), non-action or
course of  dealing  on the part of the Bank will be deemed an  extension  of, or
agreement on the part of the Bank to extend, the Expiration Date.

     1.4  Term Loans: Term Note. In addition to the foregoing, the Bank may make
one or more loans (the "Term  Loans") to the Borrower in an aggregate  principal
amount up to $500,000. A Term Loan shall be made, no more than once per calendar
quarter (except that more than one Term Loan may be made in any calendar quarter
provided  that any  additional  Term Loan in any one  calendar  quarter is in an
amount of at least $250,000),  in order to finance costs of Qualifying Equipment
or  Qualifying  Real  Property  acquired  by the  Borrower  within  the 90  days
preceding the request for such Term Loan, each Term Loan to be in such amount as
may be requested by the  Borrower;  provided  that (i) no Term Loan will be made
after the earlier of (A) December 31, 1999 or (b) the earlier termination of the
within-described  term loan facility,  pursuant to [SECTION]5.2 or [SECTION]7.7;
(ii) the aggregate  original principal amounts of all Term Loans will not exceed
$500,000;  and (iii) no Term Loan will be in an amount more than 80% of the Fair
Market Value of Qualifying Real Property  (excluding  appraisals,  environmental
assessments  and reports,  insurance  and other  closing  costs);  or 80% of the



                                       2
<PAGE>

invoiced  actual costs of the tangible  property of  equipment  and/or  fixtures
constituting  the items of Qualifying  Equipment with respect to which such Term
Loan  is  made  (excluding  taxes,  shipping,  software,  installation  charges,
training fees and other "soft  costs");  or 30% of the invoiced  actual costs of
software.  Prior to the making of each Term Loan, and as a precondition thereto,
the  Borrower  will  provide  the  Bank  with:  (i)  appraisals,   environmental
assessments  and reports,  title reports and other  information  of the relevant
Qualifying  Real  Property  or  invoices  supporting  the costs of the  relevant
Qualifying  Equipment;  or (ii) such evidence as the Bank may reasonably require
showing that the Qualifying Equipment has been delivered to and installed at the
Premises, has become fully operational, has been paid for by the Borrower and is
owned by the Borrower free of all liens and interests of any other Person (other
than the security  interest of the Bank  provided for herein);  or (iii) Uniform
Commercial  Code  financing  statements.  If  needed,  reflecting  the  relevant
Qualifying Equipment or Qualifying Real Property with respect to which such Term
Loan is  being  made;  and  (iv)  evidence  Satisfactory  to the  Bank  that the
Qualifying  Equipment  or  Qualifying  Real  Property is fully  insured  against
casualty loss,  with  insurance  naming the Bank as secured party and first loss
payee.  The Term Loans will be evidenced by the Term Note.  Interest on the Term
Loans  shall be  payable at the times and at the rate  provided  for in the Term
Note.  Overdue  principal of any Term Loan and, to the extent  permitted by law,
overdue  interest  shall bear interest at a fluctuating  rate per annum which at
all times shall be equal to the sum of (i) four (4%) percent per annum plus (ii)
the per annum  rate  otherwise  payable  under the Term Note (but in no event in
excess of the maximum rate from time to time permitted by then applicable  law),
compounded  monthly  and  payable on demand.  The  Borrower  hereby  irrevocably
authorizes  the Bank to make or cause to be made, on a schedule  attached to the
Term Note or on the books of the Bank,  at or following  the time of making each
Term Loan and of receiving any payment of  principal,  an  appropriate  notation
reflecting such transaction and the then aggregate  unpaid principal  balance of
the Term Loans. The amount so noted shall constitute  presumptive evidence as to
the amount owed by the  Borrower  with  respect to  principal of the Term Loans.
Failure of the Bank to make any such  notation  shall not,  however,  affect any
obligation of the Bank hereunder or under the Term Note.

     1.5 Principal  Repayment of Term Loans.  The Borrower shall repay principal
of each  Term  Loan in 47 equal  consecutive  monthly  installments  (each in an
amount  equal to 1/180th  of the  aggregate  principal  amount of the Term Loans
outstanding at the close of business on December 31, 1999) commencing on January
31, 2000 and continuing on the last Business Day of each month through  November
30, 2004 plus a 48th and final  payment of all  remaining  principal  and unpaid
interest  due  and  payable  on  December  31,  2004.  In any  event,  the  then
outstanding  principal  balance of each Term Loan and all interest  then accrued
but unpaid  thereon  shall be due and payable in full no later than December 31,
2004.  The  Borrower  may  prepay,  at any time,  or from time to time,  without
premium or  penalty,  the whole or any portion of any Term Loan;  provided  that
each such principal  prepayment  shall be accompanied by payment of all interest
on the sum so prepaid  accrued  but unpaid to the date of  payment. Any  partial
prepayment  of  principal of the Term Loans will be applied to  installments  of
principal  of the Term Loans  thereafter  coming due in inverse  order of normal
maturity.  Amounts  repaid or  prepaid  with  respect  to the Term Loans are not
available for reborrowing.

     1.6  Interest Rates and Payment. Interest on the Revolving Loans and on the



                                       3
<PAGE>

Term Loans shall be calculated as follows:

          (a)  Except as otherwise provided below in this [SECTION]1.6, interest
on the Revolving  Loans and on the Term Loans will be payable monthly in arrears
as provided in the Notes at a fluctuating  rate per annum (the "Floating  Rate")
which shall at all times be equal to the sum of (i) (A) for the Revolving Loans,
one half of one percent  (0.50%);  or (B) for the Term Loans,  there quarters of
one percent  (0.75%) plus (ii) the Prime Rate as defined in the Notes in effects
from time to time (but in no event in excess of the maximum  rate  permitted  by
then applicable law), with a change in such rate of interest to become effective
on each day when a change in the Prime Rate becomes effective.

          (b) Subject to the conditions set forth herein, the Borrower may elect
that all or a portion of any Revolving Loan to be made under [SECTION]1.2 or any
Term Loan to be made under  [SECTION]1.4 be made as a London  Interbank  Offered
Rate ("LIBOR") Loan at the rate of (i) (A) for a Revolving  Loan,  three percent
(3%); or (B) for a Term Loan,  three and one quarter  percent  (3.25%) plus (ii)
30, 60 or 90 day LIBOR (as the  Borrower  may  select),  as provided  for in the
Notes;  that all or any portion of any Floating Rate Loan will be converted to a
30, 60 or 90 day (as the Borrower may select)  LIBOR Loan at such rates;  and/or
that any LIBOR Loan will be continued at the expiration of the Interest  Period,
as defined herein,  as a 30, 60 or 90 day (as the Borrower may select) new LIBOR
Loan. As used herein,  "Interest  Period" shall mean , with respect to each such
advance conversion or continuation, the chosen 30,60 or 90 day period commencing
on and including the date on which such advance,  conversion or  continuation is
made and ending on and including the date  preceding the next  succeeding  date,
when payment of interest is due, or, if such  interest  payment date should fall
within thirty (30) days of the date of such advance, conversion or continuation,
the net interest payment date thereafter.

          (c)  A LIBOR Loan election shall be made by the Borrower giving to the

Bank a written or telephonic  notice received by the Bank within the time period
and  containing  the  information  described in the next  following  sentence (a
"LIBOR  Borrowing  Notice").  The LIBOR Borrowing Notice must be received by the
Bank no later than 10:00 a.m.  (Boston  time) on that day which is two  Business
Days prior to the date of any such advance conversion or continuation,  and must
specify:  (i) the amount of the LIBOR Loan requested (which shall be $500,000 or
an integral multiple of $100,000 in excess of $500,000; (ii) the particular Term
Loan(s) or Revolving Loan(s) to be so advanced,  converted or continued,  as the
case may be; and (iii) the proposed  commencement  date of the relevant Interest
Period and its 30, 60 or 90 day duration.  The Bank shall determine the LIBOR as
quoted to it by leading banks in the London Interbank  Eurodollar  Market, at or
about 5:00 p.m.  (London time) on the date a LIBOR Borrowing  Notice is received
(or, if such date is a banking  holiday in London,  of the last LIBOR  quoted to
the Bank),  which will be in effect on the date of the  advance,  conversion  or
continuation  as the case may be (which in any case must be a Business Day) with
respect to the Term Loan or Revolving  Loan or LIBOR Loan in question,  having a
maturity  date of 30, 60 or 90 days from the date of the advance,  conversion or
continuation,  as the case may be. Each determination of LIBOR by the Bank shall
be  conclusive  evidence,  in the absence of manifest  error,  or such LIBOR and


                                       4
<PAGE>

shall be promptly communicated to the Borrower.  However, if the Borrower if the
Borrower has not delivered a notice to the Bank in a timely manner in accordance
with the  provisions of this  [SECTION]1.6  (c), the Borrower shall be deemed to
have chosen to have the  interest on such  Revolving  Loan or Term Loan or LIBOR
Loan  calculated  on the  applicable  Floating Rate basis.  Any LIBOR  Borrowing
Notice shall,  upon receipt by the Bank,  become  irrevocable and binding on the
Borrower,  and the Borrower shall, upon demand and receipt of a Bank Certificate
with respect thereto,  forthwith  indemnify the Bank against any loss or expense
incurred  by the Bank as a result of any  failure by the  Borrower to borrow any
requested  LIBOR  Loan,  including,  without  limitation,  any  loss or  expense
incurred by reason of the liquidation or redeployment of deposits or other funds
acquired by the Bank to fund or maintain  such LIBOR Loan.  Notwithstanding  the
foregoing,  the Bank need not make a LIBOR Loan, convert a Floating Rate Loan to
a LIBOR Loan or continue a LIBOR Loan at any time at which there exists an Event
of Default.

          (d)  Nothing  contained  herein shall be construed as authorizing  the
Borrower,  with  respect  to the  determination  of LIBOR  (i) to choose a LIBOR
Interest  Period in  respect of which the  Interest  Period  extends  beyond the
Expiration  Date in the case of  Revolving  Loans or beyond  the due date of the
applicable  installment  in the case of Term Loans;  or (ii) to choose an amount
for an advance,  conversion or  continuation  amount greater than that permitted
under [SECTION]1.2 for Revolving Loans or [SECTION]1.4 for Term Loans.

               (e)  The  actual  annual  rate of  interest  to which  the  rates
determined in accordance  with  [SECTION]1.6(b)  are equivalent is the specified
rate multiplied by the actual number of days during the year, divided by 360:

                    (LIBOR + Margin) x 365*/360 = % per year

* (in a leap year, substitute 366 for 365). LIBOR Loan interest shall be payable
in arrears on each applicable Interest Period payment date.

               (f) In the  event  that  the  Bank  determines  that  (i) for any
reason,  adequate and reasonable methods for determining the LIBOR applicable to
any  Interest  Period  do not  exist;  or  (ii)  the  making,  conversion  to or
continuation of LIBOR Loan has been made  impracticable or unlawful by reason of
London Interbank  market  conditions or events or by compliance by the Bank with
any applicable  law,  regulation,  guideline or other or change of, or change in
the  interpretation of, any such law,  regulation,  guideline or order; or (iii)
LIBOR, in the Bank's  reasonable  determination,  does not adequately and fairly
reflect the Bank's cost in funding  such LIBOR Loans for such  Interest  Period,
then the Bank shall give Borrower notice of such  determination,  which shall be
conclusive  and binding on  Borrower,  and the Bank's  obligation  to make LIBOR
Loans shall be suspended until the Bank determines that the conditions that gave
rise to its prior determination no longer exist.

               (g)  If, due to acceleration or prepayment  (whether voluntary or
mandatory) or for any other reason,  the Bank receives payment for any principal
of any  LIBOR  Loan on any  date  prior to the  last  day of such  LIBOR  Loan's
relevant Interest Period, the Borrower shall, upon receipt of a Bank Certificate
from  the  Bank  with  respect  thereto,  pay  forthwith  to the  Bank  a  yield


                                       5
<PAGE>

maintenance  fee in an amount  computed as follows:  the current rate for United
States Treasury  securities (bills on a discounted basis shall be converted to a
bond  equivalent)  with a maturity  date closest to the last day of the Interest
Period  applicable to the affected LIBOR Loan shall be subtracted from the "cost
of funds" component (i.e.,  reserve-adjusted  LIBOR) of the fixed rate in effect
at the  date  of such  prepayment  or  conversion.  If the  result  is zero or a
negative  number,  there shall be no yield  maintenance  fee. If the result is a
positive number, then the resulting percentage shall be multiplied by the amount
of the principal balance being prepaid. The resulting amount shall be divided by
360 and  multiplied  by the number of days  remaining in the  relevant  Interest
Period.  Such amount shall be reduced to present  value  calculated by using the
number  of days  remaining  in the  relevant  Interest  Period  and by using the
above-referenced  United States  Treasury  securities rate as the discount rate.
The  resulting  amount  shall be the  yield  maintenance  fee due the Bank  upon
prepayment or conversion of the  applicable  LIBOR Loan. Any  acceleration  of a
LIBOR Loan due to an Event of Default will give rise to a yield  maintenance fee
calculated  with respect to such LIBOR Loan on the date of such  acceleration in
the same manner as though the Borrower had  exercised a right of  prepayment  at
that date, such yield maintenance fee being due and payable at that date.

     1.7  Advances and Payments.  The proceeds of all Loans shall be credited by
the Bank to a general deposit account  maintained by the Borrower with the Bank.
The  proceeds of each  Revolving  Loan will be used by the  Borrower  solely for
working  capital  purposes.  The  proceeds of each Term Loan will be used by the
Borrower solely to pay or reimburse acquisition costs of Qualifying Equipment or
Qualifying Real Property.

     The Bank may charge any general deposit account of the Borrower at the Bank
with the amount of all payments of interest,  principal and other sums when same
are due, from time to time,  under this Letter  Agreement and/or any Note and/or
with respect to any letter of credit; and will thereafter notify the Borrower of
the amount so  charged.  The  failure of the Bank so to charge any account or to
give any such  notice  shall not affect the  obligation  of the  Borrower to pay
interest,  principal or overdue principal,  overdue interest or default interest
as provided herein or in any Note or with respect to any letter of credit.

     Whenever any payment to be made to the Bank  hereunder or under any Note or
with respect to any letter of credit shall be stated to be due on a day which is
not a Business  Day,  such payment may be made on the next  succeeding  Business
Day, and  interest  payable on each such date shall  include the amount  thereof
which shall accrue during the period of such  extension of time. All payments by
the Borrower  hereunder and/or in respect of any Note and/or with respect to any
letter  of credit  shall be made net of any  impositions  or taxes  and  without
deduction, set-off or counterclaim, notwithstanding any claim which the Borrower
any now or at any  time  hereafter  have  against  the  Bank.  All  payments  of
interest,  principal and any other sum payable  hereunder  and/or under any Note
and/or with respect to any letterof  credit shall be made to the Bank, in lawful
money of the United States in immediately  available funds, at its office at One
Federal Street, 7th Floor, Boston, MA 02110 or at such other address as the Bank
may from time to time direct.  All payments received by the Bank after 2:00 p.m.
on any day shall be deemed received as of the next succeeding Business Day. All


                                       6
<PAGE>

monies received by the Bank shall be applied first to fees,  charges,  costs and
expenses  payable to the Bank under this Letter  Agreement,  any Note and/or
any of the other Loan  Documents  and/or  with  respect to any letter of credit,
next to interest  then  accrued on account of any Loans or letter of credit next
to  interest  then  accrued  on  account  of  any  Loans  or  letter  of  credit
reimbursement  obligations  and only  thereafter  to  principal  of the Loans or
letter of credit  reimbursement  obligations  being  applied  against  the Loans
and/or  such  obligations  in such order as the  Borrower  may  designate  (and,
failing  such  designation,  being  applied  first  against the letter of credit
reimbursement  obligations,  next  against the  Revolving  Loans and  thereafter
against installments of the Term Loans in inverse order of normal maturity). All
interest and fees payable hereunder and/or under nay Note shall be calculated on
the basis of a 360-day year for the actual number of days elapsed.

     1.8  Letters of Credit. At the Borrower's request,  the Bank may, from time
to time,  in its sole  discretion  issue one or more  letters  of credit for the
account of the  Borrower;  provided  that at the time of such issuance and after
giving effect thereto the Aggregate  Revolving Bank Liabilities will in no event
exceed the lesser of (i) Borrower or (ii) the then effective Borrowing Base. Any
such  letter of  credit  will be  issued  for such fee and upon  such  terms and
conditions  as may be  agreed  to by the  Bank and the  Borrower  at the time of
issuance.  The Borrower hereby authorizes the Bank, without further request from
the Borrower, to cause the Borrower's liability to the Bank for reimbursement of
funds drawn under any such letter of credit to be repaid from the  proceeds of a
Revolving Loan to be made thereunder.  The Borrower hereby irrevocably  requests
that such Revolving Loans be made.

     1.9  Conditions  to  Advance.  Prior  to the  making  of the  initial  Loan
hereunder or the issuance of any letter of credit hereunder,  the Borrower shall
deliver to the Bank duly executed copies of this Letter Agreement, the Revolving
Note,  the Term Note, all other Loan Documents and the documents and other items
listed on the Closing Agenda delivered herewith by the Bank to the Borrower, all
of which, as well as all legal matters incident to the transactions contemplated
hereby, shall be satisfactory in form and substance to the Bank and its counsel.
As a  material  condition  precedent  to the  granting  of any  advance  for the
purchase of Qualifying Real Property (including, without limitation, purchase of
the building or part of the building containing the Premises, Borrower agrees to
execute in the Bank's  favor a senior first  mortgage in a form  supplied by the
Bank for the  entirety  of the  Qualifying  Real  Property,  and, in the case of
purchase  of part of the  building  containing  the  Premises,  a  senior  first
mortgage on the entire  building and lot containing  the Premises.  As a further
material  precondition t the making of an advance for the purchase of Qualifying
Real  Property,  Borrower  agrees  that such  advance  is to be paid by the Bank
directly to the Seller of such  Qualifying Real Property at the closing and that
Borrower  will,  prior  to  such  closing,   furnish  to  the  Bank  appraisals,
environmental   assessments  and  reports,  title  information  and  such  other
documents and information as the Bank may require to ascertain the value,  clear
title,  freedom from liens and validity of the Bank's Security  Interest in such
Qualifying  Real  Property,  including  those  set  forth in the  definition  of
"Qualifying Real Property" in [SECTION]8.1 herein.

     Without  limiting  the  foregoing,  any Loan or letter  of credit  issuance
(including  the  initial  Loan or letter of credit  issuance)  is subject to the


                                       7
<PAGE>

further conditions precedent that on the date on which such Loan is made or such
letter of credit is issued ( and after giving effect thereto):

          (a)  All  statements.  representations  and warranties of the Borrower
made in this  Letter  Agreement  shall  continue  to be correct in all  material
respects as of the date of such Loan or  issuance  of such letter of credit,  as
the case may be.

          (b)  All covenants and  agreements  of the Borrower  contained  herein
and/or in any of the other Loan  Documents  shall have been complied  within all
material  respects on and as of the date of such Loan or issuance of such letter
of credit, as the case may be.

          (c)  No event which constitutes, or which with notice or lapse of time
or both  could  constitute,  an Event of  Default  shall  have  occurred  and be
continuing.

          (d)  No material  adverse  change shall have occurred in the financial
condition of the Borrower from that disclosed in the financial  statements  then
most recently furnished to the Bank.
     
     Each  request by the  Borrower for any Loan or for the issuance of a letter
of credit and each  acceptance  by the  Borrower of the  proceeds of any Loan or
delivery of a letter of credit, will be deemed a representation  and warranty by
the Borrower that at the date of such Loan or letter of credit issuance,  as the
case may be, and after giving effect  thereto all of the conditions set forth in
the foregoing clauses (a)-(d) of this 1.9 will be satisfied. Each request for a
Revolving  Loan or letter of credit  issuance will be accompanied by a borrowing
base  certificate  on a form  satisfactory  to the Bank,  executed  by the chief
financial  officer of the Borrower,  unless such a  certificate  shall have been
previously furnished setting forth the Borrowing Base as at a date not more than
30 days prior to the date of the requested  borrowing or the requested letter of
credit issuance as the case may be.

     II.  REPRESENTATIONS AND WARRANTIES

     2.1  Representations  and Warranties.  In order to induce the Bank to enter
into this Letter  Agreement and to make Loans hereunder  and/or issue letters of
credit hereunder, the Borrower warrants and represents to the Bank as follows:

          (a) The Borrower is a corporation duly organized, validly existing and
in good standing  under the laws of New Jersey.  The Borrower has full corporate
power to own its  property  and conduct its  business  as now  conducted  and as
contemplated  to be  conducted,  to grant the  security  interests  contemplated
herein and execute, deliver and perform this Letter Agreement and the other Loan
Documents. The Borrower is duly qualified to do business and in good standing in
each other  jurisdiction  in which the Borrower  maintains any  facility,  sales
office or  warehouse  and in each  other  jurisdiction  where the  failure so to

material adverse effect on the financial condition, business or prospects of the
Borrower, all such jurisdictions, as at the date of this Letter Agreement, being
listed on item 2.1(a) of the attached Disclosure  Schedule.  At the date hereof,
the borrower has no Subsidiaries, except as shown on said item 2.1(a) of the


                                       8
<PAGE>

attached  Disclosure  Schedule.  The  Borrower  is  not a  member  of  any  such
partnership or joint venture.

          (b)  At the  date of this  Letter  Agreement,  all of the  outstanding
capital stock of the Borrower is owned, of record and beneficially, as set forth
on item 2.1(b) of the attached  Disclosure  Schedule.  The Borrower owns 100% of
the outstanding capital stock of each Subsidiary.

          (c) The  execution  delivery and  performance  by the Borrower of this
Letter  Agreement and each of the other Loan Documents have been duly authorized
by all necessary corporate and other action and do not and will not:

          (i)  violate any  provision  of, or require  any  filings  (other than
               filings under the UCC), registration,  consent or approval under,
               any law, rule,  regulation,  order, writ,  judgment,  injunction,
               decree,   determination  or  award  presently  in  effect  having
               applicability to the Borrower;

               or result in a breach of or  constitute  a default or require any
               waiver or consent under nay indenture or loan credit agreement or
               any other  material  agreement,  lease or instrument to which the
               Borrower  is a  party  or by  which  the  Borrower  or any of its
               properties  may be bound or affected or require any other consent
               of any Person; or

          (d)  This Letter  Agreement  and each of the other Loan  Documents has
been duly  authorized,  executed  and  delivered  by the  Borrower and each is a

Borrower in accordance with its respective terms.

          (e) Except as  described  on item  2.1(e) of the  attached  Disclosure
Schedule, there are no actions, suits, proceedings or investigations pending or,
to the knowledge of the  Borrower,  threatened by or against the Borrower or any
Subsidiary  of  the  Borrower  before  any  court  or  governmental  department,
commission, board, bureau, agency or instrumentality, domestic or foreign, which
could hinder or prevent the consummation of the transactions contemplated hereby
or call into question the validity of this Letter  Agreement or any of the other
Loan  Documents or any other  instrument  provided for or  contemplated  by this
Letter Agreement or any of the other Loan Documents or any action taken or to be
taken in  connection  with the  transactions  contemplated  hereby or thereby or
which in any  single  case or in the  aggregate  might  result  in any  material
adverse change in the business,  prospects,  condition, affairs or operations of
the Borrower or any such Subsidiary.

          (f)  The  Borrower  is not in  material  violation  of any term of its

                                       9
<PAGE>

charter  or  by-laws  as now in effect.  As used  herein,  a material  violation
includes any  violation  that  invalidates,  or impairs the legal effect of, the
execution,  delivery or performance  of this Letter  Agreement or any other Loan
Document. Neither the Borrower nor any Subsidiary of the Borrower is in material
violation of any term of any mortgage,  indenture or judgment,  decree or order,
or any other  instrument,  contract  or  agreement  to which it is a party or by
which any of its property is bound.

          (g) The  Borrower  has filed (and has caused  each  Subsidiary  of the
Borrower to file) all federal, foreign, state and local tax returns, reports and
estimates  required to be filed by the Borrower or by any such  Subsidiary.  All
such filed  returns,  reports  and  estimates  are proper and  accurate  and the
borrower (or the Subsidiary  concerned,  as the case may be) has paid all taxes,
assessments,  impositions,  fees and other  governmental  charges required to be
paid in respect of the periods covered by such returns, reports or estimates. No
deficiencies for any tax,  assessment or governmental  charge have been asserted
or  assessed,  and the  Borrower  knows of no material  tax  liability  or basis
therefor.

          (h) The Borrower is in  compliance  with (and each  Subsidiary  of the
Borrower is in compliance  with) all  requirements  of law,  federal,  state and
local,  and all  requirements  of all  governmental  bodies or  agencies  having
jurisdiction over it, the conduct of its business, the use of its properties and
assets,  and all  premises  occupied  by it,  failure to comply with which could
(singly  or in the  aggregate  with all other  such  failures)  have a  material
adverse effect upon the assets,  business,  financial  condition or prospects of
the  Borrower  or any such  Subsidiary.  Without  limiting  the  foregoing,  the
Borrower has all the franchises,  licenses,  leases,  permits,  certificates and
authorizations  needed  for  the  conduct  of its  business  and  the use of its
properties and all premises occupied by it, as now conducted, owned and used and
as proposed to be conducted, owned and used.

          (i)  The   audited   financial   statements  of  the  Borrower  as  at
December  31,  1997 and the  management-generated  financial  statements  of the
Borrower as at September 30, 1998,  each  heretofore  delivered to the Bank, are
complete and accurate and fairly present the financial condition of the Borrower
as at the date  thereof  and for the period  covered  thereby,  except  that the
management-generated  statements  do not have  footnotes and thus do not present
the  information  which would  normally be  contained  in footnotes to financial
statements. Neither the Borrower nor any of the Borrowers's Subsidiaries has any
liability,  contingent or otherwise, not disclosed in the aforesaid December 31,
1997 and  September 30, 1998  financial  statements or in the notes thereto that
could materially affect the financial condition of the Borrower. Since September
30,  1998,  there has been no material  adverse  development  in the business or
condition of the Borrower, and the Borrower has not entered into any transaction
other than in the ordinary course.

          (j)  The principal  place of business and chief  executive  offices of
the Borrower are located at 100 Stierli Court,  Mount Arlington,  New Jersey and
those of the Borrower's  subsidiary,  Procath Corporation  ("Procath") at Cooper
Run Executive  Park  Condominium,  575 Route 73 North,  West Berlin,  New Jersey
(collectively,  the  "Premises").  All  of  the  Collateral  is  located  at the
Premises.  Except  as  described  on  item  2.1(j)  of the  attached  Disclosure
Schedule, no Collateral is located at any other address. Said item 2.1(j) of the


                                       10

attached  Disclosure  Schedule  sets forth the names and addresses of all record
owners of the Premises.

          (c)  The Borrower  owns or has a valid and  unencumbered  right to use
all of the collateral free of all Liens except those in favor of the Bank.

          (l)  None of the  executive  officers or key employees of the Borrower
is subject to any  agreement in favor of anyone  other than the  Borrower  which
limits or  restricts  that  person's  right to  engage  in the type of  business
activity  conducted  or proposed to be conducted by the Borrower or which grants
to anyone other than the Borrower  any rights in any  inventions  or other ideas
susceptible  to legal  protection  developed or conceived by any such officer or
key employee.

          (m)  The Borrower is not a party to any  contract or  agreement  which
now has or, as far as can be foreseen by the  Borrower at the date  hereof,  may
have a material adverse effect on the financial condition,  business,  prospects
or properties of the Borrower.

good faith by proceedings which serve as a matter of law to stay the enforcement

perfection  and  priority of the  security  interests  granted or intended to be

Subsidiary,  or transport or arrange the transport of, any hazardous material or
oil (the terms "hazardous material",  "oil", "site" and "vessel",  respectively,
being used herein with the meanings  given those terms in Mass.  Gen.  Laws, Ch.
21E or any  comparable  terms in any  comparable  statute in effect in any other
relevant jurisdiction).  The Borrower shall provide the Bank with written notice
of (i) the intended storage or transport of any hazardous material or oil by the

governmental authority in connection with the assessment, containment or removal
of any  hazardous  material or oil for which expense or loss the Borrower or any
Subsidiary of the Borrower may be liable.  Notwithstanding  the  foregoing,  the


                                       18
<PAGE>

Borrower and its  Subsidiaries  may use, store and transport and need not notify
the  Bank  of the  use,  storage  or  transportation  of (x)  oil in  reasonable

or machinery used in the ordinary course of their respective  businesses and (y)
hazardous  materials that are solvents,  cleaning agents or other materials used
in the ordinary course of the respective business operations of the Borrower and

effect any necessary governmental permits, licenses and approvals, complies with
all  requirements  of applicable  federal,  state and local law relating to such
use,  storage or  transportation,  follows the protective and safety  procedures
that a prudent  businessperson  conducting  a business the same as or similar to
that of the Borrower or such  Subsidiary (as the case may be) would follow,  and

licensed providers of hazardous waste removal services.

including,  without  limitation,  any  register  and patent  license,  copyright
trademark,  trade name or  franchise,  without the written  consent of the Bank,

of which shall be cumulative):

          (a)  Declare the entire unpaid principal amounts of the Revolving Note
and the Term Note then outstanding,  all interest accrued and unpaid thereon and
all other amounts payable under this Letter Agreement and all other Indebtedness
of the Borrower to the Bank to be forthwith due and payable,  whereupon the same

Note,  under the Term Note and under each and any other agreement with the Bank;
and  exercise  all other  rights  and  remedies  which  the Bank may have  under

     5.3  Set-off.  In addition  to any rights now or  hereafter  granted  under
applicable  law  and not by way of  limitation  of any  such  rights,  upon  the
occurrence of any Event of Default,  the Bank is hereby authorized at anytime or
from time to time,  without  presentment,  demand protest or other notice of any
kind to the Borrower or to any other Person,  all of which are hereby  expressly
waived,  to set off and to  appropriate  and apply any and all  deposits and any
other  Indebtedness  at any time  held or  owing  by the  Bank or any  affiliate
thereof  to or for the  credit or the  account of the  Borrower  against  and on
account of the  obligations  and  liabilities  of the Borrower to the Bank under
this Letter  Agreement  or  otherwise,  irrespective  of whether or not the Bank

or claims,  or any of them,  may then be  contingent  or  unmatured  and without
regard for the availability or adequacy of other collateral. As further security

remedies of a secured party under the UCC.



                                       22

the Bank, (i) if an Event of Default shall have occurred and the Bank shall have
accelerated  the  Revolving  Loans or (ii) if this Letter  Agreement  and/or the

have been earlier  terminated by either the Bank or the Borrower for any reason,
the  Borrower  will  forthwith  deposit with the Bank in cash a sum equal to the
total of all then undrawn amounts of all outstanding letters of credit issued by

     VI.  COLLATERAL AND INDEBTEDNESS SECURED

     6.1  Security Interest. To secure the due payment and performance of all of
the  Obligations of the Borrower to the Bank, the Borrower  hereby grants to the
Bank a continuing  security  interest in, and a Lien on, the following  property
and rights of Borrower  wherever  located  and  whether  now owned or  hereafter
acquired:

          (a)  All accounts,  contracts,  contract rights, notes, bills, drafts,
acceptances,  general  intangibles,  chattel paper,  chooses in action,  and all
other debts,  obligations and  liabilities,  in whatever form, owing to Borrower
from any person,  firm or  corporation,  or any other legal entity,  whether now
existing or  hereafter  arising,  now or  hereafter  received by or belonging or
owing to  Borrower,  for  goods  sold by it or for  services  rendered  by it or
however otherwise same may have been established or created,  all guarantees and
securities  therefor,   all  right,  title  and  interest  of  Borrower  in  the
merchandise  or  services  which  gave rise  thereto,  including  the  rights of
reclamation  and  stoppage  in  transit,  all  rights  of an  unpaid  seller  of
merchandise  or  services,  and  in the  proceeds  thereof,  including,  without
limitation,  all  proceeds  of  credit,  fire or  other  insurance,  and any tax
refunds; and

          (b)  All goods,  merchandise,  raw materials,  goods, work product and
work in process,  finished goods and other tangible personal property, now owned
or  hereafter  acquired  and held  for  sale or  lease,  or  furnished  or to be
furnished under contract of service,  or used or consumed in Borrower's business
and in the products and proceeds thereof,  including,  without  limitation,  all
proceeds  of fire or other  insurance.  This  portion  of the  Collateral  being
sometimes referred to as "Inventory;" and

          (c)  All machinery, equipment and other goods (as defined in Article 9
of the UCC)  whether now owned or  hereafter  acquired by Borrower  and wherever
located,  goods  (as  defined  in  Article  9 of the UCC)  whether  now owned or
hereafter  acquired by Borrower  and  wherever  located,  all  replacements  and


                                       23
<PAGE>

substitutions  therefor or  accessions  thereto and all  proceeds  thereof,  and
including, also without limitation, all proceeds of fire or other insurance: and

          (d)  All  of the  Borrower's  files,  books  and  records  (including,
without limitation,  all electronically  recorded data) all whether now owned or
existing or hereafter acquired, created or arising; and

          (e)  Any and all real property and fixtures  appurtenant  to such real
property now owned by the  Borrower or  purchased by the Borrower  with any Term
Loans hereunder.

     All of the  property  and  rights  set  forth  in (a)  through  (e)  above,
including, without limitation, all proceeds of fire and other insurance thereon,
are hereinafter referred to collectively as "Collateral."

     6.2  Obligations  Secured.  The  Collateral  and all  proceeds and products
thereof shall be security for all Obligations.  Until all Obligations  have been
fully satisfied.  Bank's security  interest in the Collateral,  and all proceeds
and products  thereof,  shall continue in full force and effect and Bank will at
all times after the occurrence and during the continuance of an Event of Default
(as defined herein) have the right to take physical  possession of the Inventory
and other  Collateral and to maintain such possession on Borrower's  premises or
to remove the Inventory  and other  Collateral or any part thereof to such other
places as Bank may desire.  If Bank exercises Bank's right to take possession of
the Inventory and other Collateral, Borrower shall, upon Bank's demand, assemble
the  Inventory  and other  Collateral  and make it  available to Bank at a place
reasonably convenient to Bank.

     6.3  No Disposal of Collateral.  Except for sales, licenses and leases made
in the ordinary course of business on a non-exclusive  basis and the disposal of
obsolete or worn-out equipment made in the ordinary course of business, Borrower
shall not sell, license,  assign, lease, grant a Lien on or dispose of or permit
the  sale,  license,  lease,  establishment  of a  Lien  on or  disposal  of any
Collateral  or remove any  Inventory  from the  Premises  without  Bank's  prior
written  consent.  A transfer of any interest of Borrower's in any Collateral in
total or  partial  satisfaction  of a debt shall not be deemed to be made in the
ordinary course of business.

     6.4  Perfection  of Security  Interest.  Borrower  shall sign and file,  or
permit  the  filing,  in form and  substance  satisfactory  to the Bank,  of the
financing  statements  and shall perform any and all steps  requested by Bank to
perfect Bank's security interest in the Collateral, such as, without limitation,
leasing  warehouses to Bank or its designee,  placing and maintaining  signs and
appointing  custodians.  This Letter Agreement,  coupled with the filing of such
UCC Financing  statements  with the filing  offices and public  authorities  set
forth in the Closing Agenda (which are the only locations for filing required by
the UCC),  creates  in the Bank's  favor a valid and  perfected  first  priority
security  interest  in the  Collateral,  which  security  interest  secures  the
Obligations.  If  any  Inventory  is in  the  possession  or  control  of any of
Borrower's agents or processors, Borrower shall notify such agents or processors
of Bank's  interest  therein,  and upon request  instruct  them to hold all such
Inventory  for Bank's  account  and subject to Bank's  instructions.  A physical


                                       24
<PAGE>

listing of all Inventory,  wherever located, shall be taken by Borrower whenever
requested by Bank, and a copy of each such physical listing shall be supplied to
Bank. Bank may examine and inspect the Inventory and other  Collateral on or off
the Premises at any time on reasonable  notice and during  business  hours or at
any time without any necessity for notice  following the  occurrence of an Event
of Default.

     6.5  Insurance.  Borrower  agrees to keep all the Inventory and  Collateral
insured with fire and extended  coverage as insurance  policies in amounts:  (i)
not less than that  usually  carried  by one  engaged in a like  business;  (ii)
sufficient to provide for full replacement cost coverage; and (iii) in any event
not less than that  required by Bank naming the Bank as secured  party and first
loss payee. Borrower hereby appoints Bank as attorney for Borrower in obtaining,
adjusting,  settling and canceling such insurance and endorsing any drafts.  All
premiums on such insurance shall be paid by Borrower and the policies  delivered
to the Bank. If Borrower fails to do so, the Bank may procure such insurance and
charge the cost to Borrower's loan account. As further assurance for the payment
and  performance of the  Obligations.  Borrower  hereby assigns to Bank all sums
including  returned or unearned  premiums,  which may become  payable  under any
policy of insurance on the Collateral and Borrower hereby directs each insurance
company issuing any such policy to make payment of such sums directly to Bank.

     6.6 Right to Discharge.  Bank may, at its sole option, discharge any taxes,
liens,  security interests or other encumbrances at any time levied or placed on
the  Collateral  and not  permitted  by this  Letter  Agreement  and pay for the
maintenance and preservation of the Collaterals. Borrower will reimburse Bank on
demand for any payment made or any expense  incurred  with  interest at the rate
provided in this Letter  Agreement.  Where  practical  and  consistent  with its
rights to take such actions to preserve or protect the Collateral, the Bank will
give Borrower reasonable notice of its intention to take such actions.

     6.7  Deficiency.  If in the event of the sale of the Collateral by the Bank
following an Event of Default,  the proceeds thereof are insufficient to pay all
amounts  to which  Bank is  legally  entitled.  Borrower  will be liable for the
deficiency,  together with interest  thereon at the rate provided in this Letter
Agreement and the  reasonable  fees of any attorney  employed by Bank to collect
such deficiency.

     6.8  Defense of Collateral.  The Borrower agrees to defend its title to the
Collateral  and to take all steps  reasonably  necessary  to preserve  its title
and/or  right to the  Collateral  and  ability to use same,  including,  without
limitation,  defense of any claim of infringement  of Intellectual  Property and
action against any infringers of Intellectual Property.

     6.9  Bank's Duties with Respect to Collateral.  The powers conferred on the
Bank herein are solely to protect its interest in the  Collateral  and shall not
impose any duty upon it to exercise any such powers. Except for the safe custody
of any  Collateral  actually in its  possession  and the  accounting  for monies
actually  received  by it  hereunder,  the  Bank  shall  have  no duty as to any
Collateral.  The Bank  shall not be liable  for any  acts,  omissions,  error of
judgment  or  mistakes  of  fact or law  including,  without  limitation,  acts,


                                       25
<PAGE>

omissions,  error or mistakes with respect to the  Collateral,  except for those
arising out of or in  connection  with the Bank's  gross  negligence  or willful
misconduct.  The Bank shall be deemed to have exercised  reasonable  care in the
custody and  preservation  of the Collateral in its possession if the Collateral
is accorded treatment substantially equal to that which the Bank accords its own
like  property  or  rights.  The Bank shall be under no  obligation  to take any
necessary  steps to collect any Collateral  or  preserve  rights  against  prior
parties or any other rights  pertaining to any Collateral,  but may do so at its
sole option, and all expenses incurred in so doing shall be for the sole account
of the Borrower and shall be deemed part of the Obligations.

     6.10 Other  Collateral.  This Letter Agreement shall not be construed to be
in limitation  of or in  substitution  for any other grant of security  interest
from Borrower to Bank made prior to or  contemporaneously  herewith and no other
such  grant of a  security  interest  made  subsequent  to or  contemporaneously
herewith shall be construed to be in limitation of or in  substitution  for this
Letter Agreement unless expressly and specifically provided therein.

$8,000  exclusive of costs and disbursement and pursuant to the Term Sheet dated
as of  February  9, 1999 and the  annexed  letter of the  Bank's  counsel  dated
February 5, 1999) in connection with the preparation,  execution and delivery of
this  Letter  Agreement,  the  Revolving  Note,  the  Term  Note  and all  other
instruments  and documents to be delivered in connection with any Loan or letter
of credit issued  hereunder and any  amendments or  modifications  of any of the
foregoing, as well as the costs and expenses (including, without limitation, the
reasonable  fees  and  expenses  of  legal  counsel)  incurred  by the  Bank  in

remedies under this Letter Agreement,  the Revolving Note, the Term Note and all
other  instruments  and documents  delivered or to be delivered  hereunder or in
connection herewith, all whether or not legal action is instituted. THE BORROWER
IS ON NOTICE THAT THE BANK'S AND THE  BORROWERS'  INTERESTS MAY BE DIFFERENT AND
MAY CONFLICT,  AND THAT THE BANK'S ATTORNEY REPRESENTS ONLY THE BANK AND NOT THE
BORROWER.  THE BORROWER IS THEREFORE ADVISED TO CONSULT A NEW JERSEY ATTORNEY OF
ITS OWN CHOOSING TO REPRESENT ITS INTERESTS.  In addition, the Borrower shall be
obligated to pay any and all stamp and other taxes  payable or  determined to be
payable in connection with the execution and delivery of this Letter  Agreement,
the Revolving Note, the Term Note and all other  instruments and documents to be
delivered in connection  with any  Obligation.  Borrower agrees to indemnify and

taxes  (excluding  any  corporate  excise or income taxes payable by the Bank by
reason hereof or otherwise) and other  governmental  charges in connection  with
this Letter  Agreement and the  Collateral;  (iii) exercise of the Bank's rights
with respect


                                       26
<PAGE>

to the Collateral; (iv) any enforcement, collection or other resulting therefrom
or  any   negotiations   or  other   measures  to  preserve  the  Bank's  rights
hereunder:(v)  the  custody  or  preservation  of,  or  the  sale  of  or  other
realization  upon,  any of the  Collateral;  (vi) any failure by the Borrower to
perform or observer any of the  provisions of this Letter  Agreement;  (vii) any
investigative, administrative or judicial proceeding (whether or not the Bank is
a party thereto) relating to or arising out of this Letter Agreement;  or (viii)
any bankruptcy, insolvency or other similar proceeding relating to the Borrower,
unless the Bank was at fault with respect to such liability,  loss, damage, cost
or expense or acted in bad fait with respect thereto. The Borrower's obligations
under this Section  constitute  Obligations and shall survive the termination of
this Letter Agreement. Any fees, costs, expenses or other charges which the Bank
is entitled to receive from the Borrower  under this Section shall bear interest
from the date of any  demand  therefor  until  the date  when paid at a rate per
annum  equal to the sum of (i) four (4%)  percent  plus (ii) the per annum  rate
otherwise payable under the Notes (but in no event in excess of the maximum rate
permitted by then applicable law).

     7.2  Capital Adequacy.  If the Bank shall have determined that the adoption
or phase-in  after the date hereof of any  applicable  law,  rule or  regulation
regarding  capital  requirements  for banks or bank  holding  companies,  or any
change  therein after the date hereof,  or any change in the  interpretation  or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration  thereof, or compliance
by the Bank with any  request or  directive  of such  entity  regarding  capital
adequacy  (whether  or not  having  the force of the law) has or would  have the
effect of  reducing  the  return  on the  Bank's  capital  with  respect  to the
Revolving  Loans,  the Term  Loans,  LIBOR  Loans  and/or the  within  described
revolving  and Term Loan  facilities  and/or  letters  of credit  issued for the
account of the Borrower to a level below that which the Bank could have achieved
(taking, into consideration the Bank's policies with respect to capital adequacy
immediately  before such adoption,  phase-in,  change or compliance and assuming
the Bank's  capital was then fully  utilized) but for such  adoption,  phase-in,
change of compliance  by any amount  deemed by the Bank to be material:  (i) the
Bank shall  promptly  after its  determination  of such  occurrence  give notice
thereof to the Borrower;  and (ii) the Borrower  shall pay forthwith to the Bank
as an  additional  fee such amount as the Bank  certifies  to be the amount that
will compensate it for such reduction with respect to the Revolving  Loans,  the
Term Loans, the LIBOR loans (excluding, with respect to any LIBOR loan, any such
requirement   already   included  in  such  LIBOR  loan's  reserve  rate),   the
within-described  revolving  and Term Loan  facilities  and/or  such  letters of
credit.

     A certificate of the Bank claiming compensation on under this Section shall
be conclusive in the absence of manifest error. Such certificate shall set forth
the nature of the occurrence  giving rise to such  compensation,  the additional
amount or  amounts  to be paid to it  hereunder  and the  method  by which  such
amounts were  determined.  In  determining  such  amounts,  the Bank may use any
reasonable averaging and attribution methods. No failure on the part of the Bank
to demand  compensation  on any one  occasion  shall  constitute a waiver of its
right to demand such  compensation  on any other  occasion and no failure on the
part of the Bank to deliver any  certificate in a timely manner shall reduce any
obligation of the Borrower to the Bank under this Section.

The Borrower  will pay to the Bank with respect to the within  arrangements  for
Revolving Loans, on the last day of each calendar  quarter  (commencing on March
31, 1999 as long as the  within-described  revolving  loan  arrangements  are in
effect and on the Expiration  Date,  non-refundable  commitment  fees,  computed
quarterly in arrears on the daily average unused portion of the revolving credit
amount  during the  calendar  quarter for which such  commitment  fees are to be
determined,  appropriately  prorate for any partial  calendar  quarter.  As used
herein, the "unused portion of the revolving credit amount" as at any date means
that  amount  by  which  (x)  $2,000,000  exceeds  (y) the sum of the  aggregate
principal  amount of all  Revolving  Loans then  outstanding  plus the aggregate
undrawn amounts of all letters of credit then outstanding.  Such commitment fees
will be payable,  based on such daily  average  unused  portion of the revolving
credit  amount,   at  the  rate  of  0.75%  per  annum.  In  addition,   if  the
within-described revolving financing arrangements are terminated by the Borrower
for any  reason or by the Bank as the  result  of the  Borrower's  default,  the
Borrower shall  forthwith upon such  termination  pay to the Bank a sum equal to
all of the commitment  fees which would have become due pursuant to this Section
for the period from the date of such  termination  through the  Expiration  Date
assuming that no Revolving Loans and no letters of credit are outstanding during
such period.  Fees described in this Section are in addition to any balances and
fees required by the Bank or any of its affiliates in connection  with any other
services now or hereafter made available to the Borrower.

     7.4  Other  Agreements.  The provisions of this Letter Agreement are not in
derogation  or  limitation  of any  obligations,  liabilities  or  duties of the
Borrower  under any of the other Loan  Documents or any other  agreement with or
for the benefit of the Bank. No inconsistency in default provisions between this
Letter Agreement and any of the other Loan Documents or any such other agreement
will be deemed to create any additional grace period or otherwise  derogate from
the express  terms of each such default  provisions.  No covenant,  agreement or
obligation of the Borrower contained herein, nor any right or remedy of the Bank
contained herein,  shall in any respect be limited by or be deemed in limitation
of any inconsistent or additional  provisions contained in any of the other Loan
Documents or in any such other agreement.

               any such prospective  assignee or Participant to agree in writing
               to maintain the  confidentiality  of such information to the same
               extent  as  the  Bank  would  be  required   to   maintain   such
               confidentiality.

     The  Borrower  may  terminate  this  Letter  Agreement  and  the  financing

     7.8  Consent  to  Jurisdiction.  The  Borrower  irrevocably  submits to the

sitting  within  The  Commonwealth  of  Massachusetts  over any suit,  action or
proceeding  arising out of or relating to this Letter Agreement and/or any Note.
The Borrower  irrevocably  waives,  to the fullest extent  permitted by law, any
objection  which it may now or hereafter have to the laying of venue of any such
suit,  action or proceeding  brought in such a court and any claim that any such
suit,  action or  proceeding  has been  brought in an  inconvenient  forum.  The
Borrower  agrees  that final  judgment  in any such suit,  action or  proceeding
brought in such a court shall be enforced in any court of proper jurisdiction by
a suit upon such judgment, provided that service of process in such action, suit
or  proceeding  shall have been effected upon the Borrower in one of the manners
specified  in the  following  paragraph  of this  [SECTION]6.8  or as  otherwise

mail, postage prepaid,  return receipt requested, to it at its address set forth
in  [SECTION]7.6  or (ii) by serving a copy  thereof  upon it at its address set

                                       30
<PAGE>

Agreement,  and the  application  of such  provision to Persons,  properties  or
circumstances  other  than  those  as to  which it has  been  held  invalid  and
unenforceable,  shall not be affected thereby, and each provision of this Letter
Agreement shall be valid and enforced to the fullest extent permitted by law.

     7.10 Replacement  Note.  Upon  receipt of an affidavit of an officer of the
Bank as to the loss,  theft,  destruction  or  mutilation  of any Note or of any
other Loan  Document  which is not of public record and, in the case of any such
mutilation, upon surrender and cancellation of such Note or other Loan Document,
the Borrower  will issue,  in lieu  thereof,  a  replacement  Note or other Loan
Document in the same principal  amount (as to any Note) and in any event of like
tenor.

     7.11 Usury.  All  agreements  between the  Borrower and the Bank are hereby
expressly  limited  so that in no  contingency  or event whatsoever,  whether by
reason of acceleration  of maturity of the Notes or otherwise,  shall the amount
paid or  agreed  to be paid to the  Bank for the use or the  forbearance  of the
Indebtedness  represented  by any Note  exceed  the  maximum  permissible  under
applicable law. In this regard,  it is expressly agreed that it is the intent of
the Borrower and the Bank,  in the  execution,  delivery and  acceptance  of the
Notes,  to contract in strict  compliance  with the laws of The  Commonwealth of
Massachusetts.   If,  under  any   circumstances   whatsoever,   performance  or
fulfillment  of any  provision  of any of the  Notes  or any of the  other  Loan
Documents at the time such  provision  is to be  performed  or  fulfilled  shall
involve  exceeding the limit of validity  prescribed by applicable law, then the
obligation so to be performed or fulfilled shall be reduced automatically to the
limits of such  validity,  and if under any  circumstances  whatsoever  the Bank
should ever receive as interest an amount which would exceed the highest  lawful
rate,  such amount  which would be  excessive  interest  shall be applied to the
reduction of the principal balance evidenced by the Notes and not to the payment
of interest.  The  provisions  of this Section  7.11 shall  control  every other
provision of this Letter Agreement and of each Note.

     7.12 Generally Accepted  Accounting  Principles or ("GAAP").  Any financial
calculation to be made, all financial statements and other financial information
to be  provided,  and all books and  records to be kept in  connection  with the
provisions  of this  Letter  Agreement  shall be in  accordance  with  generally
accepted  accounting  principles  consistently  applied during each interval and
from  interval to  interval;  provided,  however,  that in the event  changes in
generally  accepted  accounting  principles  shall be mandated by the  Financial
Accounting  Standards  Board  or  any  similar  accounting  body  of  comparable
standing,  or should be recommended by Borrower's certified public accounts,  to
the extent such changes  would affect any financial  calculations  to be made in
connection   herewith,   such  changes  shall  be  implemented  in  making  such
calculations  only from and after  such date as  Borrower  and Bank  shall  have
amended this  Agreement  to the extent  necessary to reflect such changes in the
financial and other covenants to which such calculations relate.

     7.13 WAIVER OF JURY TRIAL.  THE  BORROWER  AND THE BANK  HEREBY  KNOWINGLY,
VOLUNTARILY  AND  INTENTIONALLY  MUTUALLY  WAIVE THE RIGHT TO A TRAIL BY JURY IN
RESPECT OF ANY CLAIM BASED HEREON,  ARISING OUT OF, UNDER OR IN CONNECTION  WITH
THIS LETTER AGREEMENT, ANY NOTE OR ANY OTHER LOAN DOCUMENTS OR OUT OF ANY COURSE

<PAGE>

OF CONDUCT,  COURSE OF DEALING,  STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS
OF ANY PARTY.  THIS WAIVER  CONSTITUTES  A MATERIAL  INDUCEMENT  FOR THE BANK TO
ENTER INTO THIS LETTER AGREEMENT AND TO MAKE LOANS AS CONTEMPLATED HEREIN.

receiver or trustee to be appointed for any of its assets or affairs;  (viii) if
the customer or account  debtor has failed to pay other  Receivables  so that an
aggregate of 25% of the total Receivables owing to the Borrower by such customer

Receivable is owed by the United  States  Government or any agency or department
thereof  (unless  assigned  to the Bank under the Federal  Assignment  of Claims
Act); or (x) if the Bank reasonably  believes that collection of such Receivable
