us that immediately prior to the Acquisition, a wholly owned subsidiary ("Merger

Sub") of St. John Knits International, Incorporated, a wholly owned subsidiary
- ---                                                                           
of the Company ("SJKI"), will merge with and into the Company, with the Company
                 ----                                                          
being the surviving corporation (the "Reorganization").  In connection with the
                                      --------------                           
Reorganization, the existing stockholders of the Company will exchange their
shares of common stock of the Company ("Company Common Stock") for shares of
                                        --------------------                
common stock of SJKI ("SJKI Common Stock"), resulting in the Company becoming a
                       -----------------                                       
wholly owned subsidiary of SJKI.  You have further advised us that, in
connection with the Acquisition, (a) Vestar will form a limited liability
company ("Holdco"), which will form a subsidiary ("Newco") and (b) immediately
          ------                                   -----                      
prior to the Reorganization (i) Vestar and certain co-investors reasonably
satisfactory to CSI will contribute approximately $153,637,000 of cash equity to
Holdco in consideration for the issuance of an 84.1% limited liability company
interest in Holdco ("Holdco Interest"), (ii) certain members of management of
                     ---------------

                  ---------------

mately $29,069,000) and (iii) Holdco will contribute approximately $146,527,000
of cash equity to Newco in consideration for the issuance of 100% of the common
stock of Newco. You have further advised us that certain members of management
of the Company may be offered the opportunity to purchase SJKI Common Stock from
SJKI representing not more than 5% of the outstanding capital stock of SJKI and
that any such purchase would reduce the amount of Vestar's contribution to
Holdco and may be funded by loans from Vestar. You have further advised us that
in connection with the Acquisition, Newco, SJKI, the Company and Merger Sub will
enter into an agreement and plan of merger (the "Merger Agreement"), pursuant to
                                                 ----------------

                                                                  ----------
consisting of a $155,000,000 term loan and a $25,000,000 revolving credit
facility, (b) SJKI will issue up to $160,000,000 principal amount of its senior
subordinated notes (the "Notes") in a public offering or in a Rule 144A offering
                         -----
or other private placement (which Notes will be guaranteed, on a senior
subordinated basis, by the Company and those subsidiaries of SJKI that guarantee
or otherwise provide credit support for the Facilities), (c) Newco will merge
with and into SJKI (the "Merger"), (d) at the effective time of the Merger, the
                         ------
outstanding shares of capital stock of SJKI held by its stockholders (the
"Sellers") (other than the shares held by Holdco, which will be canceled) will
 -------
be converted into a combination of aggregate cash consideration equal to
approximately $447,581,000 and 456,000 shares of SJKI Common Stock, such that,
following the Merger, certain of the Sellers will continue to own approximately
7.0% of the outstanding capital stock of SJKI having an aggregate value of
approximately $13,684,000, (e) at the effective time of the Merger, outstanding
in the money options to buy shares of SJKI Common Stock will be cashed out for
an aggregate amount of approximately $14,003,000, (f) at the effective time of

be converted into SJKI Common Stock representing approximately 93.0% of the
outstanding capital stock of SJKI having an aggregate value of approximately
$182,706,000, and (g) SJKI will pay transaction costs and expenses in connection
with the foregoing in an amount not to exceed $20,000,000 (the foregoing
