NOTE 1 - BASIS OF PRESENTATION

The accompanying interim financial statements are unaudited, but include all
adjustments (consisting of normal recurring accruals) which are, in the opinion
of management, necessary for a fair statement of the results for such periods.

The unaudited interim consolidated financial statements should be read in
conjunction with the audited December 31, 1995, consolidated financial
statements of the Company.

The results of operations for the interim periods are not necessarily
indicative of the results to be expected for the full year ending December 31,
1996.

On July 23, 1996, the Company completed an initial public offering of its
Common Stock on the London Stock Exchange.  The Company issued 4,190,477 shares
of Common Stock at L.5.25 ($8.14) per share raising L.22,000,000 ($34,100,000).
The offering raised net proceeds of approximately $30,500,000, which proceeds
will be used to repay certain indebtedness and to fund working capital,
operations and capital expenditures.

In June 1996, the Company completed a private placement of $5,000,000 principal
amount of the Company's 15% Subordinated Promissory Notes due May 1, 1997, (the
"15% Notes"), of which $4,250,000 were purchased for cash and $750,000 were
issued upon conversion of other indebtedness.  Warrants to purchase 360,000
shares of the Company's Common Stock at $8.00 per share were issued in
connection with the 15% Notes.

In April 1996, Martin S. Brown loaned $1,000,000 to the Company in exchange for
a short-term unsecured note bearing interest at an annual rate of 12%.  In May
1996, Mr. Brown converted  $750,000 principal amount of the 12% note into an
equal principal amount of the Company's 15% Notes.  The $250,000 principal
balance on the 12% note is payable in full, together with accrued interest, on
August 18, 1996.

During the first half of 1996, the Company repaid a $950,000 short-term line of
credit borrowing due to SunTrust Bank .

During the six months ended June 30, 1996, the Company's subsidiary, TAb
Australia, Pty. Ltd. borrowed an additional $227,000 on its collateralized loan
from the South Australian Minister for Primary Industries.  As of June 30,
1996, the Company had drawn a total of $487,000 on this loan.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         The following discussion and analysis of the financial condition and
results of operations of the Company should be read in conjunction with the
financial statements and notes thereto.  This discussion and analysis contains
both historical and forward looking information.  The forward looking
statements are made pursuant to the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995.  Forward looking statements may be
significantly impacted by certain risks and uncertainties described herein.

GENERAL

         Since its inception, Therapeutic Antibodies Inc. ("TAb" or the
"Company") has been in the development stage, devoting its efforts and
resources to drug discovery and development programs relating to the
development of highly purified, polyclonal antibodies for the treatment of
disease.  Since inception the Company's revenues have been from contract
agreements with corporate partners, product sales, grant income, interest
income, and insurance and value added tax recoveries.  Net losses have been
incurred each year since its inception and the Company does not expect to
realize positive cash flow during at least the next two years due to continued
spending on research, product development and increasing requirements for
process development, preclinical and clinical testing, regulatory affairs,
initial manufacturing activities and administration.  To fund these activities,
the Company conducted additional financings in the first six months of 1996.
See "Liquidity and Capital Resources."

         The Company conducts its operations from its headquarters in the
United States and through subsidiaries located in the United Kingdom, Australia
and New Zealand.  International operations are primarily located in the United
Kingdom.


RESULTS OF OPERATIONS

Three Months Ended June 30, 1996 Compared to Three Months Ended June 30, 1995

         Revenues for the three months ended June 30, 1996, increased by 64% to
$311,000 from $189,000 for the three months ended June 30, 1995. This increase
is due to an increase in ViperaTAb(TM) sales and an increase in grant income.
Second quarter 1996, ViperaTAb(TM) sales increased 40% to $147,000 from
$105,000 in the second quarter ended June 30, 1995.  Grant income increased
784% to $88,000 from $10,000.  The Company received a $79,000 grant in the
second quarter ended June 30, 1996, from the Economic Development Authority of
the Government of South Australia to assist the Company with the expansion of
its Australian operations.

         Expenses increased by 72% to $3,649,000 in the second quarter of 1996,
from $2,116,000 in the second quarter of 1995.  Research and development
expenses increased by 82% to $2,334,000 in the second quarter of 1996 from
$1,285,000 in the second quarter of 1995, as a result of increases in the
levels of clinical trials of products in development, including CytoTAb(TM),
CroTAb(TM), DigiTAb(TM) and PulchellaTAb(TM).  Management expects that research
and development expenses will continue to increase in the remaining two
quarters of 1996 as the Company's current clinical trials progress.





                                       6
<PAGE>   7

         General and administrative expenses increased by 50% in the second
quarter of 1996 to $500,000 from $333,000 in the second quarter of 1995.  The
increase is attributable to the hiring of new personnel and the additional
associated costs.

         Marketing and distribution expenses in the second quarter of 1996,
decreased by 16% to $107,000 compared to $127,000 in the second quarter of 1995
due to a reduction in marketing personnel and related salary expenses.  This
decrease was partially offset by an increase of $13,000 in distribution
expenses over the same period in 1995 as a result of the increased sales of
ViperaTAb(TM).

         Depreciation and amortization expense in the second quarter of 1996,
increased by 79% to $369,000 from $206,000 compared to the second quarter of
1995.  This increase is the result of the initial depreciation of the
$4,000,000 capital expenditure relating to the expansion of the Welsh
production facility which was placed in service in December 1995.

         Interest expense in the second quarter of 1996 increased by 91% to
$293,000 from $153,000 in the second quarter of 1995 as a result of increased
borrowing by the Company to fund working capital and operations, including the
issuance of $5,305,000 principal amount of the Company's 6% Convertible Notes
due October 1, 2000 (the "6% Notes") and $5,000,000 principal amount of its 15%
Subordinated Promissory Notes due May 1, 1997, (the "15% Notes").  Management
anticipates that the Company will repay up to $4,750,000 of certain of its debt
obligations from the proceeds of the sale of Common Stock in the United Kingdom
in July 1996.  See "Liquidity and Capital Resources".  Any such repayment of
debt would result in a decrease in the Company's interest expense from current
levels.


Six Months Ended June 30, 1996 Compared to Six Months Ended June 30, 1995

         TAb's revenues for the first six months of 1996 increased by 33% to
$391,000 from $294,000 for the same period of 1995.  ViperaTAb(TM) sales
increased by 42% to $151,000 for the first half of 1996 from $106,000 for the
first half of 1995 while non-core contract production revenue decreased 32% to
$72,000 from $105,000.  Grant income for the six months ended June 30, 1996,
increased by 390% to $98,000 from $20,000 in the six months ended June 30,
1995.  In June 1996 the Company received a $79,000 grant from the Economic
Development Authority of the Government of South Australia to assist the
Company with the expansion of its Australian operations.

         Expenses for the first half of 1996 increased by 80% to $7,456,000
from $4,144,000 for the same period in 1995.  Research and development expenses
during the same periods increased by 67% to $4,171,000 from $2,503,000 as a
result of increased clinical trial activities, including clinical trials for
CytoTAb(TM), CroTAb(TM), DigiTAb(TM) and PulchellaTAb(TM).  These costs are
related to manufacturing TAb's products for clinical trials and conducting
clinical trials.

         General and administrative expenses for the first half of 1996
increased by 32% to $948,000 from $717,000 for the first half of 1995.  This
increase relates primarily to expanded staffing and related overhead expenses.

         Marketing and distribution expenses decreased by 28% to $169,000 in
the first half of 1996 from $235,000 in the first half of  1995 due to a
reduction in marketing personnel and related salary expenses.





                                       7
<PAGE>   8


         Depreciation and amortization expense in the six month period ended
June 30, 1996, increased by 82% to $702,000 from $386,000 compared to the six
month period ended June 30, 1995. This increase is the result of the initial
depreciation of the $4,000,000 capital expenditure relating to the expansion of
the Welsh production facility, which was placed in service in December 1995.

         Interest expense in the first half of 1996 increased by 112% to
$608,000 from $286,000 in the first half of 1995 due to increased borrowings by
the Company including the issuance of the 6% and 15% Notes.

         In the first quarter of 1996, the Company recorded a one-time debt
conversion expense of $801,597, relating to the conversion of an aggregate of
$2,565,105 of principal and interest on the Company's 6% Notes into shares of
Common Stock, which represents the difference between the stated conversion
price on the debt of $8.00 per share and the actual conversion price of $5.50.

         The Company's net loss for the first half of 1996, was $7,100,000
compared to a net loss of $3,800,000 for the first half of 1995.  This increase
was due to the one-time debt conversion expense and the other increased
expenses described above.


LIQUIDITY AND CAPITAL RESOURCES

         Since its inception, TAb has been in the development stage, devoting
its efforts and resources to drug discovery and development programs.  Capital
resources have been used for the establishment and expansion of production
facilities, research and development, clinical testing and to meet TAb's
increased working capital needs in connection with such activities.  Management
does not expect revenues from product sales to be a significant source of
funding until additional products receive regulatory approval. Future capital
requirements will depend on numerous factors, including the progress of its
research programs and clinical trials, the development of regulatory
submissions, the commercial viability of the Company's products, the
development of sales, distribution and marketing capabilities, and the terms of
any new licensing arrangements. Financing for the Company's operating and
capital requirements historically has been provided by the sale of equity,
convertible debt and through other borrowings.

         At June 30, 1996, the Company had cash and cash equivalents totaling
$2,168,000.  The Company's net cash used in operating activities during the six
months ending June 30, 1996, totaled $5,592,000, an increase of 54% from the
six months ending June 30, 1995.  Capital expenditures of $796,000 in the first
six months of 1996 related primarily to the expansion of the Company's
production facility in Australia.  TAb anticipates that capital expenditures in
1996 will be less than $1,700,000 and expects to fund these capital
expenditures with existing resources, a portion of the UK offering (discussed
below), and the $1,180,000 loan from the South Australian Minister for Primary
Industries (discussed below).

         On July 23, 1996, the Company completed an initial public offering of
its Common Stock on the London Stock Exchange.  The Company issued 4,190,477
shares of Common Stock at L.5.25 ($8.14) per share raising L.22,000,000
($34,100,000).  The offering raised net proceeds of approximately $30,500,000,
which proceeds will be utilized to fund working capital, operations and capital
expenditures.  Approximately $4,750,000 of the proceeds of the U.K. offering
will be used to repay the Company's 15% Notes and certain other indebtedness.





                                       8
<PAGE>   9

         During the six months ended June 30, 1996, TAb Australia Pty. Ltd.,
the Company's Australian operating subsidiary ("TAb Australia"), made a
$227,000 draw on its collateralized loan from the South Australian Minister for
Primary Industries.  Under this loan agreement, TAb Australia may draw up to
$1,180,000 to assist with construction and equipping of buildings at its
Turretfield location in South Australia.  The loan bears interest at an annual
rate of 11%, payable annually.  Principal is to be repaid in ten equal annual
installments.  As of June 30, 1996, the Company had outstanding draws of
$487,000 on this loan.

         In June 1996, the Company completed a private placement of $5,000,000
principal amount of the Company's 15% Subordinated Promissory Notes due May 1,
1997, of which $4,250,000 were purchased for cash and $750,000 were issued upon
conversion of indebtedness.  Each $250,000 unit of the 15% Notes was
accompanied by a Stock Purchase Warrant to purchase 18,000 shares of Common
Stock at $8.00 per share. Warrants to purchase 360,000 shares of  Common Stock
were issued in connection with the 15% Notes.

         In April 1996, Martin S. Brown loaned $1,000,000 to the Company in
exchange for a short-term unsecured note bearing interest at an annual rate of
12%.  In May 1996, Mr. Brown converted  $750,000 principal of the 12% Note into
an equal principal amount of the Company's 15% Notes.  The $250,000 principal
balance on the 12% Note is payable in full, together with accrued interest, on
August 18, 1996.  It has been agreed to extend both of these debt obligations
through the end of 1998.

         The Company repaid a $950,000 short-term line of credit borrowing from
SunTrust Bank in the first half of 1996.

          (a)   the BORROWER fails to pay when due any payment

                MINISTER of the failure, is treated as being received by the
                BORROWER under Clause 16; or

          (b)   the BORROWER fails to comply with and perform its
                obligations under this AGREEMENT (other than an obligation to

                the fourteenth day after notice, by the MINISTER, of the
                failure is treated as being received by the BORROWER under
                Clause 16; or

          (c)   a representation or warranty made in connection
                with or under this AGREEMENT or, the making of it or any

                under this AGREEMENT, proves at any time to have been or to be
                incorrect, inaccurate or misleading in any material respect; or

                term, condition or provision is void, voidable, illegal or
                invalid or unenforceable; or

          (e)   a Liquidator, Receiver, Receiver or Manager, Voluntary
                Administrator, Mortgagee's Agent in Possession or Official

                between the BORROWER and its creditors or any class of them or
                a RELATED CORPORATION and its creditors or any class of them or
                the BORROWER or any RELATED CORPORATION makes an assignment for

                as they mature; or

                average of ten (10) FTE within ten (10) years of the DRAWDOWN
                DATE; or

          (h)   there occurs any material adverse change in the condition or
                stability of the BORROWER or a RELATED CORPORATION which in
                the reasonable opinion of the MINISTER could result in the
                BORROWER being unable to perform its obligations under this
                AGREEMENT; or

          (i)   an inspector is appointed to investigate the

                detrimental to the interest of the MINISTER; or

          by notice in writing to the BORROWER specifying the relevant EVENT OF
          DEFAULT designate a date as an early termination date for the
          purposes of this AGREEMENT ("EARLY TERMINATION DATE") being a date

<PAGE>   9


          earlier than the third day after the notice is treated as being
          received by the COMPANY under Clause 16.

    5.3   If the MINISTER gives a notice to the BORROWER designating an
          EARLY TERMINATION DATE and whether or not the relevant EVENT OF
          DEFAULT is continuing, the BORROWER will pay to the MINISTER on the
          EARLY TERMINATION DATE the OUTSTANDING MONEY, on receipt of which the
          MINISTER'S obligations under this AGREEMENT will terminate.

           (b)  claimed to be void, voidable or unenforceable, in whole or in
           part, and that claim is upheld, conceded or compromised in whole or

he is purchasing the Notes for his own account for investment and not as agent 
or nominee, except as disclosed in writing to the Company, with no present
intention of dividing his participation with others or reselling any such
Notes, and not with a view to the resale or distribution in whole or in part
thereof in violation of the Securities Act.  Nothing herein contained, however,
shall prevent a Purchaser from requesting the Company to register the Notes so
issued in the name of either the Purchaser's nominee, the Purchaser's immediate
family members, or an "affiliate" of the Purchaser, as such term is defined in
the Exchange Act or in regulations promulgated thereunder.  If a Purchaser
submits such a request, the Company will not withhold its consent unreasonably.
The Purchaser acknowledges that appropriate stop transfer instructions will be

risk of the investment represented by his purchase of the Notes for an
indefinite period.

partnership, all of its members have such capacity; and if the Purchaser is a 
corporation or trust, it has the requisite power, is authorized or otherwise 
duly qualified, and has taken all necessary corporate action, to acquire and 
pay for the Notes.

he has received and read copies of the Form 10-K and the Company's Proxy  
Statement with respect to the Annual Meeting of Shareholders on April 25, 1996  
(the "Proxy"), that he has had access during the course of the transaction and 
prior to his purchase of the Notes to such information relating to the Company  
as he has desired, that he has had the opportunity to ask questions of and      
receive answers from the Company and its representatives concerning the terms 
and conditions of the sale of the Notes and to obtain such additional
information about the business and financial condition of the Company as the
Purchaser or his representative has requested (to the extent the Company
possessed such information or could acquire it without unreasonable effort or
expense), necessary to verify the accuracy of the information contained in the
Form 10-K and the Proxy.

                6.6     Restrictions on Transfer of the Notes.  The Purchaser
understands (i) that the Notes have not been registered under the Securities
Act and, unless required by a particular state's securities law, they have not
been registered or qualified under any applicable state securities laws; and
(ii) that the Notes may be required to be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration is available.  The Purchaser also understands that Rule 144 (or any
successor rule) promulgated under the Securities Act, which provides for
certain limited routine sales of unregistered securities, is not available with
respect to the Notes, that the Company has not covenanted to satisfy the
conditions for resale pursuant to Rule 144 (or any successor rule), and that
compliance with an available exemption under applicable securities laws may be
required for a sale or other disposition of the Notes.

                6.7     Legends.  The Purchaser is aware that the Notes shall 
bear a legend, in addition to any legend required by any particular state's 
securities laws, or include language substantially as follows:

           THE SALE OF THIS NOTE HAS NOT BEEN REGISTERED UNDER THE
           SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY
           STATE SECURITIES LAW.  THIS NOTE HAS BEEN ACQUIRED FOR
           INVESTMENT AND NOT WITH A VIEW TO OR FOR RESALE IN
           CONNECTION WITH THE DISTRIBUTION THEREOF.  NO
           DISPOSITION OF THIS NOTE MAY BE MADE IN THE ABSENCE OF
           AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND
           COMPLIANCE WITH APPLICABLE STATE SECURITIES LAWS OR AN
           OPINION OF COUNSEL TO THE COMPANY TO THE EFFECT THAT
           SUCH DISPOSITION IS IN COMPLIANCE WITH THE ACT AND
           APPLICABLE STATES SECURITIES LAWS.

Appropriate stop transfer instructions will be entered in the transfer records
of the Company.

                6.8     Right to Rely; Indemnification.  The Purchaser 
understands and intends that the Company and its management will rely upon the  
Purchaser's representations made in this Agreement and in the Purchaser 
Information Questionnaire attached hereto, and they are entitled to rely upon
each and all of the same without further inquiry.  The Purchaser covenants and
agrees to indemnify and hold harmless the Company, its officers, directors,
employees and agents, from and against any and all liability, loss, cost or
expense, including reasonable attorneys' fees, arising from or incurred in
connection with any misrepresentation or omission of the Purchaser contained
herein or in the Purchaser Information Questionnaire. The indemnification
provided hereby includes indemnification for the loss of any exemption from
registration of the Notes under federal or state securities laws which is based
on the Purchaser's representations concerning his status as an Accredited
Investor or his investment intent.

                6.9     Periodic Confirmation of Outstanding Balance of Notes.  
From time to time, Purchasers may receive from the Company or the Company's 
financial advisors a non-binding request for confirmation of the outstanding
principal balance on Purchaser's Notes.  Purchaser hereby agrees to complete,
sign and date such confirmation and to promptly return it in accordance with the
instructions contained therein.

                6.10    Survival of Covenants.  The covenants of the Purchaser
contained herein shall survive the execution and delivery of this Agreement and 
the Other Agreements and the purchase of the Notes.


                7.      Description of the Notes.

                7.1     General. The Notes will be the unsecured subordinated   
obligations of the Company, will mature in twelve months on  May 1, 1997 ("the
Maturity Date"), and will be limited to $5,000,000 aggregate principal amount. 
The Notes will bear interest at the rate of 15% per annum from the date of
issuance, payable quarterly on August 1 and November 1, 1996, February 1 and on
May 1, 1997, to the person in whose name such Note is registered in the transfer
records of the Company at the close of business on the July 15, October 15,
January 15 and April 15 preceding each respective payment date.

                7.2     Warrant.  Each Unit of the Notes  shall be accompanied 
by a stock purchase warrant to purchase up to 18,000 shares of the Company's 
Common Stock (the "Warrants")  at an  exercise price of $8.00 per share of 
Common Stock (the "Exercise Price").  The Warrants shall expire on May 1, 1999.

     Holders desiring to exercise their Warrants shall present their Warrants
at the principal office of the Company as set forth in Section 7.6 hereof.
Promptly upon receipt of such Warrants, the Company shall record such exercise
on the Company's transfer records and, within fifteen (15) business days of the
receipt of such Warrants, shall cause to be issued in the name of the holder
set forth in the Company's records one or more certificates evidencing the
number of shares of the Company's Common Stock that the holder of such Warrants
has requested for exercise at the Exercise Price.  In the event a holder
desires to exercise less than all of his or her Warrants, the Company shall
deliver to such holder, in addition to certificates representing shares of
Common Stock, a replacement Warrant evidencing the balance of such holder's
Warrants not tendered for exercise.  The Warrants and certificate evidencing
any shares of Common Stock issued upon exercise of the Warrants shall bear a
restrictive legend substantially in the form set forth in Section 6.7 hereof.

                7.3     Redemption of Notes. At any time prior to maturity, the 
Company may, at its option, redeem the Notes, in whole or in part, upon not 
less than thirty (30) days prior notice mailed to each holder of Notes to be
redeemed at the holder's address appearing in the Company's transfer records, at
a redemption price equal to 100% of the outstanding principal amount of the
Notes, plus accrued interest to the redemption date (the "Redemption Price").

     Upon receipt by the holder of a Note of the written notice of the
Company's intent to redeem his or her Note in accordance with this Section 7.3,
the holder, within the time specified in such notice, shall tender said Note to
the Company at its principal offices as set forth in Section 7.6 hereof.  Upon
presentment of the Note, the Company shall tender to such holder cash in an
amount equal to the Redemption Price for the Note so redeemed.  In the event
the Company elects to redeem less than all of the principal amount of a Note
held by a holder, the Company shall issue to such holder a replacement Note
evidencing the balance of the principal amount of such holder's Note not called
for redemption.

                7.4     Subordination.  The Notes will be subordinated and 
subject to the extent and in the manner set forth herein, in right of payment 
to the prior payment in full of all Senior Indebtedness of the Company.  "Senior
Indebtedness" is defined as any indebtedness of, or guarantees by, the Company
for money borrowed, or any indebtedness incurred in connection with an
acquisition or with a merger or consolidation, (a) outstanding on the date of
this Agreement (except as provided below), (b) any renewal, extension,
modification or refunding thereof or (c) hereafter created and for which the
Company has granted a security interest in property or assets of the Company,
for the payment of which the Company (which term includes the Company's
subsidiaries) is at the time of determination responsible or liable as obligor,
guarantor or otherwise, other than indebtedness as to which, in the instrument
creating or evidencing the same or pursuant to which the same is outstanding,
it is provided that such indebtedness is subordinate in right of payment to any
other indebtedness of the Company or that such indebtedness is subordinate to
or equally subordinate with the Notes; provided, however, that the Notes shall
rank pari passu with the Company's 6% Convertible Notes due October 1, 2000.
Notwithstanding any other provision of this Agreement, nothing contained herein
shall limit the amount of Senior Indebtedness which the Company may incur, nor
prohibit the Company from creating liens on its property for any purpose.

     The terms of the Senior Indebtedness may prohibit the payment on account
of principal or interest on the Notes if any default or event of default with
respect to any Senior Indebtedness shall have occurred and be continuing.  Upon
any acceleration of the principal due on the Notes or any payment or

                          THERAPEUTIC ANTIBODIES INC.
                      PURCHASER INFORMATION QUESTIONNAIRE

     The purpose of this Questionnaire is to assist Therapeutic Antibodies Inc.
(the "Company") in determining that its offering of up to $5,000,000 principal
amount of the Company's 15% Subordinated Promissory Notes due May 1, 1997 (the
"Notes") is exempt from registration under applicable federal and state
securities laws.  All information provided herein will be treated in
confidence, except that this Questionnaire may be presented to such parties as
are deemed appropriate or necessary to establish the availability of exemptions
from registration under federal and state securities laws.  By his signature
below, each person or entity who purchases any of the Notes (each a
"Purchaser") represents that (i) the information contained herein is complete
and accurate and may be relied upon by the Company, and (ii) the Purchaser will
notify the Company immediately of any material change in any of such
information occurring prior to the purchase of any Notes by the undersigned.
The Purchaser agrees to indemnify and hold the Company, its officers,
directors, employees and agents, harmless from any loss or expense incurred by
them by reason of the Company's reliance hereupon.


A.   The undersigned is an individual or entity described below (please check
     applicable descriptions):

      ( )    A natural person whose individual net worth or joint net
             worth with that person's spouse, at the time of his purchase,
             exceeds $1,000,000.

      ( )    A natural person who had an individual income in excess of
             $200,000 in each of the two most recent years or joint income with
             that person's spouse in excess of $300,000 in each of those years
             and has a reasonable expectation of reaching the same income level
             in the current year.  ["Income" may include amounts normally
             excluded from "adjusted gross income" such as long-term capital 
             gain deductions, depletion deductions, interest exclusions and 
             losses allocable to a limited partner.  However, "income" is not
             necessarily synonymous with "revenue"; for example, a self-employed
             person should deduct operating expenses to give an accurate
             indication of income.]

      ( )    A corporation, partnership or revocable trust in which all
             of the equity owners meet one of the criteria above.  [If this
             description is checked, each owner of the partnership or 
             corporation and each grantor of the revocable trust must complete
             this Section A and sign and date the Questionnaire.]

      ( )     Other accredited entity.  [Please describe.  See Section
              6.1 of the Securities Purchase Agreement.]

C.   The undersigned has previously purchased securities which were sold in
     reliance on a private placement exemption from registration under the
     Securities Act of 1933, as amended:

           YES       NO

   (Initial here)       The undersigned has carefully reviewed the risks of, and
                        other considerations relating to, an investment in the 
                        Company.  The undersigned has been furnished any 
                        materials, and had the opportunity to have answered 
                        any questions, relating to the business and financial 
                        condition of the Company, and the Company has given
                        complete and satisfactory answers to all inquiries that 
                        the undersigned has put to it concerning the matters 
                        mentioned above.

                        The undersigned has such knowledge and experience in
                        financial and business matters that the undersigned is
                        capable of evaluating the merits and risks of an 
                        investment in the securities of the Company and of 
                        protecting the undersigned's own interests in 
                        connection with this transaction; the undersigned is 
                        able to bear the economic risks of the investment and 
                        to afford the complete loss of the investment.  The 
                        undersigned does not desire to utilize a Purchaser 
                        Representative in connection with evaluating such
                        merits and risks.

     Upon a breach of any promise made in this Note, at the option of the
holder, the entire indebtedness hereby evidenced shall become due, payable and
collectible then or thereafter, as the holder may elect, regardless of the date
of maturity. The holder may waive any default before or after the same has been
declared and restore this Note to full force and effect without impairing any
rights hereunder, such right of waiver being a continuing one.

     The Borrower, for itself, its successors and assigns, covenants and
agrees, and each holder, by accepting this Note or any portion hereof, likewise
covenants and agrees, that this Note shall be subordinated and subject, to the
extent and in the manner herein set forth, in right of payment to the prior
payment in full of all Senior Indebtedness (as defined in the Note Purchase
Agreement) of Borrower.  Senior Indebtedness shall continue to be Senior
Indebtedness and entitled to the benefits of the subordination provisions set
forth herein irrespective of any amendment, modification, or waiver of any term
of the Senior Indebtedness or extension or renewal of the Senior Indebtedness.
The provisions of this paragraph are made for the benefit of all holders of
Senior Indebtedness, and any such holder may proceed to enforce such
provisions.

     The maker of this Note, and all who may become liable for same, jointly
and severally waive presentment for payment, protest, notice of protest, notice
of nonpayment of this Note, demand and all legal diligence in enforcing
collection.

     Notwithstanding any provisions to the contrary in this Note, or in any
documents relating hereto, in no event shall this Note or such documents
require the payment or permit the charging or collection of interest in excess
of the maximum amount permitted by the laws of the State of Tennessee. If any
such excess of interest is contracted for, charged or received under this Note
or under the terms of any document relating hereto, then in any such event (a)
the provisions of this paragraph shall govern and control, (b) neither the
Borrower nor any other person or entity now or hereafter liable for the payment
hereof shall be obligated to pay the amount of such interest to the extent that
it is in excess of the maximum amount of interest permitted by the laws of the
State of Tennessee, (c) any such excess which may have been collected shall be
applied, at the holder's option, either as a credit against the then unpaid
principal amount hereof or refunded to the Borrower by the holder and (d) the
effective rate of interest shall be automatically reduced to the maximum lawful
rate of interest allowed under the laws of the State of Tennessee as now or
hereafter construed by the courts having jurisdiction thereof. It is further
agreed that, without limitation of the foregoing, all calculations of the rate
of interest contracted for, charged or received under the Note or any such
other documents which are made for the purpose of determining whether such rate
exceeds the maximum lawful rate of interest, shall be made, to the extent
permitted by the laws of the State of Tennessee, by amortizing, prorating,
allocating and spreading, during the period of the full stated term of the
indebtedness evidenced hereby, all interest at any time contracted for, charged
or received from Borrower or otherwise by the holder or holders hereof in
connection with such indebtedness. If for any reason, the laws of any
jurisdiction other than Tennessee should be deemed to govern the construction
of this Note, then and in such event, all references in this paragraph to the
laws of the State of Tennessee shall mean the laws of such other jurisdiction.
