                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


1.   The Company is a wholly-owned subsidiary of Chattem, Inc. ("Chattem") and
     is included in Chattem's consolidated financial statements and tax returns.

2.   The accompanying unaudited financial statements have been prepared in
     accordance with generally accepted accounting principles for interim
     financial information and the instructions to Form 10-Q and Rule 10-01 of
     Regulation S-X. Accordingly, they do not include all of the information and
     footnotes required by generally accepted accounting principles for complete
     financial statements. These financial statements should be read in
     conjunction with the audited financial statements and related notes thereto
     included in the Company's Form 10-K for the year ended November 30, 1998
     and with the audited consolidated financial statements and related notes
     thereto included in Chattem's Annual Report to Shareholders for the year
     ended November 30, 1998. The accompanying unaudited financial statements,
     in the opinion of management, include all adjustments necessary for a fair
     presentation. All such adjustments are of a normal recurring nature.

3.   The results of operations for the interim periods presented are not
     necessarily indicative of the results to be expected for the respective
     full years.

4.   The Company had no outstanding debt as of the periods presented and
     therefore incurred no interest expense.

6.   The Company is a wholly-owned subsidiary of Chattem which provides the
     Company with the use of all of its information technology ("IT") systems.
     Chattem is currently in the process of replacing most of its current IT
     systems which are approximately 20 years old; consequently, the new IT
     system will be year 2000 compliant. As a result, the year 2000 compliance
     requirements are considered only a portion of Chattem's systems replacement
     effort. This replacement is expected to be completed on or before December
     1, 1999 at a total cost to Chattem of approximately $2,000,000. Such costs
     are being capitalized as incurred.

     Chattem is also reviewing the possible impact of the year 2000 problem
     on its customers and suppliers and has requested and received from a 
     majority of its principal customers and suppliers written statements 
     regarding their knowledge of and plans for meeting the year 2000 
     compliance requirements.

     The Company's business could be adversely affected should Chattem or other
     entities with whom Chattem does business be unsuccessful in completing
     critical modifications in a timely manner.

7.   On December 21, 1998 the Company and Chattem acquired the DEXATRIM,
     SPORTSCREME, ASPERCREME, CAPZASIN-P, CAPZASIN-HP and ARTHRITIS HOT brands
     from Thompson Medical Company, Inc. ("Thompson") for $95,000,000. The
     purchase price consisted of $90,000,000 cash and 125,500 shares of
     Chattem's common stock. The cash portion of the purchase price was financed
     with a new senior credit facility (the "Credit Facilities"). The Company is
     the guarantor of the new $165,000,000 credit facility, which consists of a
     $115,000,000 term loan and a $50,000,000 working capital revolving loan of
     which $17,500,000 was outstanding at February 28, 1999. The proceeds of the
     new facility were used to fund the Thompson acquisition and related fees
     and expenses and refinance existing bank indebtedness for which the Company
     was guarantor.

8.   The Credit Facilities were provided by a syndicate of commercial banks, led
     by Bank of America as agent. The Credit Facilities include a $50,000,000
     revolving credit facility and a $115,000,000 term loan. The Credit
     Facilities were used to refinance existing senior debt, to finance the
     acquisition of the Thompson products and related fees and expenses and to
     finance working capital and other general corporate needs. The $50,000,000
     revolving credit facility matures on the earlier of (i) December 21, 2003
     and (ii) the date on which the term loan is repaid in full. The
     $115,000,000 term loan matures on December 21, 2003. The Credit Facilities
     contain covenants, representations, warranties and other agreements by
     Chattem that are customary in loan agreements and securities instruments
     relating to financing of this type.

     Chattem may elect either the greater of (i) the prime rate or federal funds
     rate plus .5% or (ii) a floating rate or Eurodollar interest rate option
     applicable to the term and revolving line loans under the Credit
     Facilities. The prime rate and Eurodollar interest rate options are based
     on a base rate plus a rate margin that fluctuates on the basis of Chattem's
     senior leverage ratio.

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

COMPARISON OF THREE MONTHS ENDED FEBRUARY 28, 1999 AND 1998

On December 21, 1998 the Company and Chattem acquired the DEXATRIM, 
SPORTSCREME, ASPERCREME, CAPZASIN-P, CAPZASIN-HP and ARTHRITIS HOT brands 
from Thompson Medical Company, Inc. for $95,000,000. The purchase price 
consisted of $90,000,000 cash and 125,500 shares of Chattem's common stock. 
The cash portion of the purchase price was financed with a new senior credit 
facility. The Company is the guarantor of the new $165,000,000 credit 
facility, which consists of a $115,000,000 term loan and a $50,000,000 
working capital revolving loan of which $17,500,000 was outstanding at 
February 28, 1999. The proceeds of the new facility were used to fund the 
Thompson acquisition and related fees and expenses and refinance existing 
bank indebtedness for which the Company was guarantor.

The following narrative represents management's comparative analysis of the
material changes in the year-to-date results of operations of the Company
pursuant to General Instruction H(2)(a) of Form 10-Q:

Royalty income increased $1,402,000, or 89.9%, for the three months ended
February 28, 1999, from the corresponding period of the prior year. The increase
was primarily due to the acquisition of the BAN brand and the Thompson products
in March and December 1998, respectively.

Amortization expense increased $1,455,000, or 189.0%, for the three months ended
February 28, 1999, from the corresponding period of the prior year. The increase
was largely due to the purchase of the BAN and Thompson products' trademarks in
March and December 1998, respectively.
