         This Amendment No. 2 (the "Amendment") amends and supplements the
Tender Offer and Schedule 13E-3 Transaction Statement on Schedule TO filed with
the Securities and Exchange Commission on July 24, 2001, as amended on July 24,
2001 (the "Schedule TO"), by Credit Suisse Group, a corporation organized under
the laws of Switzerland ("CSG"), Credit Suisse First Boston, Inc., a Delaware
corporation and an indirect wholly owned subsidiary of CSG ("CSFB"), and
CSFBdirect Acquisition Corp., a Delaware corporation and a wholly owned
subsidiary of CSFB ("Purchaser"). The Schedule TO relates to the offer by
Purchaser to purchase all outstanding shares of common stock of the series
designated Credit Suisse First Boston (USA), Inc. CSFBdirect Common Stock, par
value $0.10 per share (the "Shares"), of Credit Suisse Boston (USA), Inc., a
Delaware corporation (the "Company"), at a price of $6.00 per Share, net to the
seller in cash, upon the terms and subject to the conditions set forth in the
Offer to Purchase dated July 24, 2001, as amended on July 24, 2001 (the "Offer
to Purchase"), and in the related Letter of Transmittal, copies of which are
filed as Exhibits (a)(1) and (a)(2) of the Schedule TO. Capitalized terms used
and not defined herein shall have the meanings given to such terms in the Offer
to Purchase and the Schedule TO.

Item 1.  Summary Term Sheet

         The Summary Term Sheet of the Offer to Purchase is hereby amended and
supplemented by adding the following new Question No. 5:

         "ARE HOLDERS OF THE CSFBDIRECT STOCK ENTITLED TO VOTE ON THE ADOPTION
         OF THE MERGER AGREEMENT?

                  Under the amended and restated certificate of incorporation of
         the Company and Delaware law, the affirmative vote of the holders of at
         least a majority of the shares of the series of common stock designated
         Credit Suisse First Boston (USA), Inc. Common Stock of the Company is
         required to adopt the merger agreement, if necessary. Holders of the
         CSFBdirect stock are not entitled to vote to adopt the merger
         agreement. Consequently, CSFB can adopt the merger agreement without
         the affirmative vote of any other stockholder of the Company,
         regardless of how many shares of CSFBdirect stock are tendered in the
         offer."

Item 2.  Subject Company Information

         Item 2 of the Schedule TO is hereby amended and supplemented to include
the following information:

         6.       Price Range of Shares; Dividends

                  The first paragraph of this section on page 44 of the Offer to
         Purchase is amended and restated in its entirety to read as follows:

                  "The Shares are listed and principally traded on the New York
         Stock Exchange ("NYSE") under the ticket symbol "DIR." The following
         table sets forth, for the quarters indicated, the high and low sales
         prices per Share on NYSE as reported by the Dow Jones News Service.
         There were no cash dividends declared on the Shares in 1999, 2000 and
         2001."


Item 4.  Terms of the Transaction

         Item 4 of the Schedule TO is hereby amended and supplemented to include
the following information:

         2.       Acceptance for Payment and Payment for Shares

                  The first paragraph of this section on page 38 of the Offer to
         Purchase is amended and restated in its entirety to read as follows:

                  "Upon the terms and subject to the conditions of the Offer
         (including, if the Offer is extended or amended, the terms and
         conditions of any such extension or amendment), Purchaser will accept
         for payment all Shares validly tendered (and not properly withdrawn in
         accordance with the procedures described in "The Offer - Withdrawal
         Rights") prior to the Expiration Date promptly after the occurrence of
         the Expiration Date. Purchaser will pay for all Shares validly tendered
         and not withdrawn promptly following the acceptance of Shares for
         payment pursuant to the Offer. See "The Offer - Terms of the Offer;
         Expiration Date."

         12.      Certain Conditions of the Offer

                  The last paragraph of this section on page 51 of the Offer to
         Purchase is amended and restated in its entirety to read as follows:

                  "The foregoing conditions are for the sole benefit of
         Purchaser and CSFB and may be asserted by Purchaser or CSFB regardless
         of the circumstances giving rise to any such condition or may be waived
         by Purchaser or CSFB in whole or in part at any time and from time to
         time in their sole discretion. The failure by CSFB or Purchaser at any
         time to exercise any of the foregoing rights will not be deemed a
         waiver of any such right; the waiver of any such right with respect to
         particular facts and other circumstances will not be deemed a waiver
         with respect to any other facts and circumstances; and each such right
         will be deemed an ongoing right that may be asserted at any time and
         from time to time. All conditions to the Offer will be satisfied or
         waived prior to the Expiration Date."

Item 5.  Past Contacts, Transactions, Negotiations and Agreements

         Item 5 is of the Schedule TO is hereby amended and supplemented to
include the following information:

         1.       Background of the Offer

                  The third full paragraph of this section on page 13 of the
         Offer to Purchase is amended and restated in its entirety to read as
         follows:

                  "On April 24, 2001, the Special Committee met again with
         representatives of Fried Frank and Lazard, who briefed the Special
         Committee on the status of their due diligence investigation. At this
         meeting the Special Committee and its advisors also discussed the
         status of pending stockholder litigation against the Company arising
         out of CSG's acquisition of DLJ and analyzed, for purposes of
         negotiation with CSFB, whether there was any merit to the fiduciary
         claims that had been asserted in the pending Delaware litigation. See
         "The Offer--Certain Litigation." The Special Committee never
         quantified the value, if any, of those claims."

                  The third full paragraph of this section on page 15 of the
         Offer to Purchase is amended and restated in its entirety to read as
         follows:

                  "On July 11, 2001, the Company Board met to consider the
         Special Committee's recommendations regarding the Offer and the Merger.
         Following a review of the terms of the Offer and the Merger and taking
         into account the arms-length negotiations between the parties, the
         terms of the Merger Agreement and the status of the pending stockholder
         litigation against the Company, the Company Board by unanimous vote of
         all directors present and voting at the meeting, with Brady W. Dougan,
         Hamilton E. James and Joe L. Roby absent from the meeting, and acting
         upon the recommendation of the Special Committee, (i) determined that
         it is fair to and in the best interests of the holders of Shares (other
         than Purchaser or its affiliates) to consummate the Offer and the
         Merger, upon the terms and subject to the conditions of the Merger
         Agreement and in accordance with Delaware Law; (ii) approved and
         declared advisable the Merger Agreement and the Transactions; and (iii)
         resolved to recommend that the holders of Shares (other than Purchaser
         or its affiliates) accept the Offer and tender their Shares pursuant to
         the Offer."

Item 13.  Information Required by Schedule 13E-3

         Item 13 of the Schedule TO is hereby amended and supplemented to
include the following information:

         2.       Recommendation of the Special Committee and the Company Board;
                  Fairness of the Offer and the Merger

                  The second paragraph of the "CSFBdirect Business Operating and
         Financial Condition" clause in the subsection entitled "The Special
         Committee" of this section on page 16 of the Offer to Purchase is
         amended by adding the following sentence at the end thereof:

                  "The Special Committee recognized that, while consummation of
         the Offer and the Merger will result in all of the holders of Shares
         (other than Purchaser or its affiliates) being entitled to receive
         $6.00 in cash for each of their Shares, it will eliminate the
         opportunity for such holders to benefit from increases, if any, in the
         value of the CSFBdirect Business following the Merger."

                  The "Financial Terms of the Transaction/Premium to Market
         Price" clause in the subsection entitled "The Special Committee" of
         this section on page 17 of the Offer to Purchase is amended by adding
         the following sentence as a new paragraph number 5 at the end thereof:


                  "Specifically, in reaching its determination referred to
         above, the Special Committee considered (i) the current market price of
         the Shares; (ii) the historic market price of the Shares; (iii) an
         analysis of the sum of the parts valuation of the CSFBdirect Business;
         (iv) the presentations made by Lazard; and (v) the opinion of Lazard,
         dated July 11, 2001 that was delivered to the Special Committee. The
         Special Committee did not consider either (i) the net book value of the
         CSFBdirect Business or (ii) the going concern value of the CSFBdirect
         Business because the Special Committee believed that the analyses it
         considered were more reflective of the indicative valuation of the
         CSFBdirect Business."

         3.       Opinion of Investment Banker

                  The fourth paragraph of this section on page 25 of the Offer
         to Purchase is amended and restated in its entirety to read as follows:

                  "Under the terms of Lazard's engagement, the Company has
         agreed to pay Lazard a fee of approximately $2 million for its
         services, $1.25 million of which is not contingent upon the
         consummation of the Offer or the Merger. The Company has also agreed to
         reimburse Lazard for its reasonable out-of-pocket expenses, including
         attorney's fees, and to indemnify Lazard and certain related parties
         against certain liabilities, including liabilities arising under the
         federal securities laws, relating to, or arising out of, its
         engagement. See "The Offer--Fees and Expenses."

         5.       Purpose and Structure of the Offer and the Merger; Reasons of
                  CSFB and CSG for the Offer and the Merger

                  The paragraph entitled "Reasons for the Offer and the Merger"
         of this section on page 27 of the Offer to Purchase is amended and
         restated in its entirety to read as follows:

                  "CSFB has determined that its acquisition of the Shares would
         give it greater flexibility in conducting the operations of the
         CSFBdirect Business. In particular, CSFB believes that it may be able
         to realize greater synergies between the CSFBdirect Business and the
         other businesses of CSFB and its affiliates if it were able to
         reallocate assets currently allocated to the CSFBdirect Business or
         transfer assets to the CSFBdirect Business without regard to the
         procedures described in the Company's Amended and Restated Certificate
         of Incorporation. In addition, the acquisition of the Shares would
         eliminate the disclosure and periodic filing requirements of the United
         States securities laws with respect to the CSFBdirect Business. CSFB
         believes therefore that the acquisition of the Shares should enable it
         to rationalize its diverse operations, reduce related expenditures and
         save management time. CSFB, as the owner of the Common Stock, also
         desires that the Company achieve the benefits described below.

                  CSFB originally acquired the Common Stock of the Company in
         the fall of 2000 and subsequently reviewed the operations of the
         CSFBdirect Business. CSFB made the initial CSFB Proposal and
         subsequently commenced the Offer after its management had sufficient
         time to identify the benefits from the acquisition of the Shares.


                  The Company, as a subsidiary of CSFB, has reasons for the
         Merger similar to those of CSFB, including the realization of the
         operational efficiencies described above. In addition, at such time as
         no Shares are owned by the public, the Company will no longer have to
         expend the management resources required to interact with financial
         analysts and respond to investors' queries in respect of the CSFBdirect
         Business. Furthermore, the Company will be saved the expense, both in
         management time and accountants' fees, of preparing financial
         statements and certain disclosure specific to the CSFBdirect Business.

                  The Purchaser is engaged in the transaction because it was
         formed by CSFB specifically for the purpose of effecting the Offer and
         the Merger.

                  CSG, as the indirect owner of CSFB, has economic interests
         aligned with those of CSFB and therefore would benefit from CSFB
         realizing the benefits described above.

                  With respect to the unaffiliated holders of Shares, the
         purpose of the Offer and the Merger is to present such holders of
         Shares with the opportunity to receive $6.00 in cash in exchange for
         their Shares, giving them a significant premium over the trading prices
         immediately preceding the Offer. See "The Offer--Price Range of Shares;
         Dividends."
