                       NOTES TO THE UNAUDITED PRO FORMA
                       CONDENSED COMBINING BALANCE SHEET


Note 1.  Basis of Presentation
         ---------------------

     The pro forma information presented is not necessarily indicative of the
results of operations or the combined financial position that would have
resulted had the merger been consummated at the beginning of the periods
indicated, nor is it necessarily indicative of the results of operations in
future periods or the future financial position of the combined company.

     Under generally accepted accounting principles, the transaction will be
accounted for as a pooling of interests and, as such, the assets and liabilities
of KSB will be combined with those of Camden at book value. In addition, the
statements of income of KSB will be combined with the statements of income of
Camden as of the earliest period presented. The unaudited pro forma combining
statements of income give effect to the merger as if the merger occurred at the
beginning of the earliest period presented. The unaudited pro forma combining
balance sheet assumes the merger was consummated on September 30, 1999.

Note 2.  Accounting Policies and Financial Statement Classifications
         -----------------------------------------------------------

     The accounting policies of both companies are in the process of being
reviewed for consistency. As a result of this review, certain conforming
accounting adjustments may be necessary. The nature and extent of these
adjustments have not been determined but are not expected to be significant.

Note 3.  Merger and Restructuring-Related Charges
         ----------------------------------------

     The following table provides detail of the estimated charges by type, post-
tax:

                                       Estimated
     Type of Cost                      Costs (in thousands)
     ------------                      --------------------

     Personnel                              $  165
     Technology and operations                 300
     Facilities                                 65
     Transaction cost and other              1,600
                                            ------
          Total                             $2,130


     Personnel-related costs consist primarily of charges related to employee
severance, termination of certain employee benefit plans and employee assistance
costs for separated employees. Technology and operations costs include
accelerated depreciation in excess of normal scheduled depreciation and certain
liabilities that will be incurred as a result of the elimination of duplicate
systems. Facilities charges consist of lease termination costs and other
facilities-related exit costs, as well as accelerated depreciation in excess of
normal depreciation, resulting from consolidation of duplicate headquarters and
operational facilities.

     These charges have not been reflected in the Unaudited Pro Forma Combining
Statement of Income since they are nonrecurring. The unaudited pro forma
financial information does not give effect to any cost savings in connection
with the pending acquisition.

     The unaudited pro forma financial information presented herein does not
reflect the impact of any divestitures that may be required as part of the
combination.

Note 4.  Pro Forma Adjustments
         ---------------------

     Pro forma adjustments to accrued expenses and other liabilities and
retained earnings reflect the $2.4 million merger and restructuring-related
charge and a $270,000 reduction in the deferred tax liability for the
anticipated tax benefit of such charge. For additional information on the
merger-and restructuring-related charges. (See Note 3).

Note 5.  Stock Repurchase Plan
         ---------------------

     Camden has had a stock repurchase plan seeking to repurchase stock since
September 1996. The original plan was to seek to repurchase up to five percent
of its outstanding shares. On October 13, 1998, the Camden Board modified the
plan to increase to $6 million the maximum amount of outstanding shares to be
repurchased during the subsequent twelve month period. During the period since
May 1, 1997, a date two years prior to Camden's discussions with KSB, Camden
repurchased 274,682 shares. (See Note 7).

Note 6.  Stock Exchange
         --------------

     The pro forma stockholders' equity accounts of Camden have been adjusted to
reflect the issuance of shares of Camden common stock in exchange for all of the
outstanding shares of KSB common stock, and the retirement of KSB's treasury
stock.

     The 1,481,800 shares of Camden common stock expected to be issued pursuant
to the acquisition of KSB are based upon 1,304,401 net KSB shares outstanding as
of August 31, 1999 and the exchange ratio of 1.136 shares of Camden common stock
for each share of KSB common stock.


Note 7.  Stock Reissuance
         ----------------

     In connection with the merger, Camden expects to reissue approximately
125,000 shares of common stock pursuant to a registration statement on Form S-3
under the Securities Act of 1933, as amended. This share reissuance is required
for the proposed transaction to be accounted for as pooling of interests in
accordance with GAAP. There can be no assurances that the estimated share
reissuance will be more than or less than this estimate. The unaudited Pro Forma
Combining Balance Sheets have been adjusted to reflect this transaction.

     All issuances are assumed to occur on June 30, 1999, at Camden's closing
price of $20.875 per share and are assumed to be issued from treasury shares
with an average book value of $17.90 per share as of June 30, 1999.
