CREDIT SUISSE TRUST – SMALL CAP CORE II PORTFOLIO
YOUR VOTE IS IMPORTANT

Dear Beneficial Owner:

Shares of Credit Suisse Trust – Small Cap Core II Portfolio (the “Acquired Portfolio”), a series of Credit Suisse Trust (the “Trust”), have been purchased at your direction by certain insurance companies (“Participating Insurance Companies”) for allocation to certain of their separate accounts established for the purpose of funding variable annuity contracts, variable life insurance contracts, and tax qualified pension and retirement plans. The Participating Insurance Companies as the shareholders of record and legal owners of those separate accounts, have been asked to approve an Agreement and Plan of Reorganization (the “Agreement”) whereby the Acquired Portfolio will be combined with and into Credit Suisse Trust – Small Cap Core I Portfolio, also a series of the Trust (the “Acquiring Portfolio”), in a tax-free reorganization (the “Acquisition”). As an owner of a variable contract with an interest in one or more of those separate accounts, the Participating Insurance Companies are asking you for instructions as to how to vote the shares of the Acquired Portfolio that are attributable to your variable contract at an upcoming special meeting of the shareholders of the Acquired Fund (the “Special Meeting”). Under the terms of the proposal, the Acquiring Portfolio would acquire all of the assets and liabilities of the Acquired Portfolio.

For simplicity, in the attached prospectus/proxy statement you may be referred to as “the shareholder” since your vote and the votes of other contract owners who have instructed the Participating Insurance Companies to invest in the Acquired Portfolio, will determine whether each proposal will be approved or adopted.

Important Information About the Acquisition

The Board of the Trust and Credit Suisse Asset Management, LLC (“Credit Suisse”), the investment adviser to each Portfolio, believe that the Acquisition is in the best interests of the Acquired Portfolio and its shareholders.

As noted and further described in the attached Prospectus/Proxy Statement, there are no material differences between the investment objectives and policies of the Portfolios.

The Acquiring Portfolio has the same co-administrators, distributor, custodian, transfer agent, independent registered public accountant and counsel as the Acquired Portfolio and because the Portfolios are part of the same Trust they are overseen by the same Board of Trustees. The closing of the Acquisition (the “Closing Date”) is expected to be on or about [ ], 2007.

If shareholders of the Acquired Portfolio approve the Agreement, the Acquired Portfolio will be liquidated upon consummation of the Acquisition and subsequently terminated as a series of the Trust. In the event the Agreement is not approved, you will continue to be a shareholder of the Acquired Portfolio and the Board of the Trust will consider other possible courses of action available to it, including resubmitting the Acquisition proposal to shareholders.

Upon consummation of the Acquisition, shareholders of the Acquired Portfolio will become shareholders of the Acquiring Portfolio, with an aggregate net asset value equal to the aggregate net asset value of such shareholder’s investment in the Acquired Portfolio immediately prior to the Acquisition. No sales or other charges will be imposed in connection with the Acquisition. In the opinion of counsel, no gain or loss will be recognized by the shareholders of the Acquired Portfolio for federal income tax purposes as a result of their exchange of Acquired Portfolio shares of beneficial interest for Acquiring

Portfolio shares pursuant to the Acquisition, and the Acquired Portfolio generally will not recognize gain or loss for such purposes. Credit Suisse or its affiliates will bear all expenses incurred in connection with the Acquisition.

The Special Meeting will be held on [ ], 2007 to consider the Acquisition set forth in the Acquired Portfolio’s Notice of Special Meeting. We strongly invite your participation by asking you to review, complete and return your proxy promptly.

Detailed information about the proposal is described in the attached Prospectus/Proxy Statement. THE BOARD OF THE TRUST UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOR OF THE PROPOSAL SET FORTH IN THE ACQUIRED PORTFOLIO’S NOTICE OF SPECIAL MEETING. On behalf of the Board of the Trust, I thank you for your participation as a shareholder and urge you to please exercise your right to vote by completing, dating and signing the enclosed proxy card. A self-addressed, postage-paid envelope has been enclosed for your convenience; if you prefer, you can fax the proxy card to [SOLICITOR] & Co., Inc (“[SOLICITOR]”), the Acquired Portfolio’s proxy solicitor, Attn.: [ ], at [ ]. We also encourage you to vote by telephone or through the Internet. Proxies may be voted by telephone by calling [ ] between the hours of [ ] a.m. and [ ] p.m. (Eastern time) Monday through Saturday or through the Internet using the Internet address located on your proxy card.

Voting by fax, telephone or through the Internet will reduce the time and costs associated with the proxy solicitations. When the Acquired Portfolio records proxies by telephone or through the Internet, it will use procedures designed to (i) authenticate shareholders’ identities, (ii) allow shareholders to authorize the voting of their shares of beneficial interest in accordance with their instructions and (iii) confirm that their instructions have been properly recorded. Shareholders voting via the Internet should understand that there may be costs associated with electronic access, such as usage charges from Internet access providers and telephone companies, that must be borne by the shareholder. We have been advised that Internet voting procedures that have been made available to you are consistent with the requirements of applicable law.

Whichever voting method you choose, please read the full text of the Prospectus/Proxy Statement before you vote.

If you have any questions regarding the proposed Acquisition, please feel free to call [SOLICITOR] at [ ] who will be pleased to assist you.

IT IS VERY IMPORTANT THAT YOUR VOTING INSTRUCTIONS BE RECEIVED PROMPTLY.

Sincerely,

/s/ J. Kevin Gao

CREDIT SUISSE TRUST – SMALL CAP CORE II PORTFOLIO
IMPORTANT NEWS FOR PORTFOLIO SHAREHOLDERS

While we encourage you to read the full text of the enclosed Prospectus/Proxy Statement, here is a brief overview of the proposal you are being asked to vote on.

Q & A: QUESTIONS AND ANSWERS

Q: WHAT IS HAPPENING?

A: Credit Suisse Asset Management, LLC (“Credit Suisse”) is proposing to combine the assets of Credit Suisse Trust – Small Cap Core II Portfolio (the “Acquired Portfolio”), a series of Credit Suisse Trust (the “Trust”), with Credit Suisse Trust – Small Cap Core I Portfolio, also a series of the Trust (the “Acquiring Portfolio”). The shareholders of the Acquired Portfolio are being asked to vote on an Agreement and Plan of Reorganization (the “Agreement”) for the assets and liabilities of the Acquired Portfolio to be acquired by the Acquiring Portfolio in a tax-free exchange of shares (the “Acquisition”). If the Agreement is approved and the Acquisition consummated, you would no longer be a shareholder of the Acquired Portfolio, but would become a shareholder of the Acquiring Portfolio.

Q: WHAT ARE THE DIFFERENCES BETWEEN MY PORTFOLIO AND THE ACQUIRING PORTFOLIO?

A: As noted and further described in the attached Prospectus/Proxy Statement, there are no material differences between the investment objectives and policies of the Portfolios. Both Portfolios have substantially similar primary investments and identical risk factors.

The Acquiring Portfolio has the same investment adviser, co-administrators, distributor, custodian, transfer agent, independent accountant and counsel as the Acquired Portfolio and because the Portfolios are part of the same Trust they are overseen by the same Board of Trustees. The closing of the Acquisition (the “Closing Date”) is expected to be on or about [ ], 2007.

Q: WHAT WILL HAPPEN TO PORTFOLIO EXPENSES?

A: The Acquisition is expected to result in lower gross and net annual operating expenses for Acquired Portfolio shareholders. For the fiscal year ended December 31, 2006, the Acquiring Portfolio’s and Acquired Portfolio’s total expenses unaudited were 1.11% and 1.29% (net of waivers and reimbursements, and 1.31% gross), respectively. These total expense ratios are based on the management fee structures previously in place which have since been reduced. Current expense ratios taking the new fee structure into account are 0.92% for the Acquiring Portfolio and 1.13%, for the Acquired Portfolio–a difference of 21 basis points in favor of the Acquiring Portfolio. The total expenses of the Acquiring Portfolio following the Acquisition are expected to be lower than those for the Acquired Portfolio during the fiscal year ended December 31, 2006. Please see the enclosed Prospectus/Proxy Statement for information on the comparative fees and expenses (including pro forma expenses) of the Portfolios.

Q: WHAT ARE THE BENEFITS OF THE TRANSACTION?

A: The Board of Trustees of the Trust believes that shareholders may benefit from the proposed Acquisition, in part, because the Acquisition will result in a single larger fund with a potentially lower expense ratio. The proposed Acquisition may result in efficiencies due to a larger asset base. The following pages give you additional information on the proposed Acquisition on which you are being asked to vote.

Q: WILL I INCUR TAXES AS A RESULT OF THE TRANSACTION?

A: The Acquisition is expected to be a tax-free event. Shareholders of the Acquired Portfolio will not recognize capital gains or losses on the exchange of their shares of beneficial interest of the Acquired Portfolio for Acquiring Portfolio shares. Shareholders will incur capital gains or losses if they sell their shares of beneficial interest in the Acquired Portfolio before the Acquisition becomes effective or sell (or exchange) their Acquiring Portfolio shares after the Acquisition becomes effective. Shareholders will also be responsible for tax obligations associated with periodic dividend and capital gains distributions that occur prior to and after the Acquisition. The Acquired Portfolio will pay a dividend of any undistributed net investment income and capital gains, which may be substantial, immediately prior to the Closing Date. Please note that qualifying retirement accounts are exempt from such tax consequences.

Q: WHAT HAPPENS IF THE PLAN IS NOT APPROVED?

A: In the event the Agreement is not approved, you will continue to be a shareholder of the Acquired Portfolio and the Board of Trustees of the Trust will consider other possible courses of action available to it, including resubmitting the Acquisition proposal to shareholders.

Q: HOW DO THE BOARD MEMBERS OF THE TRUST RECOMMEND THAT I VOTE?

A: AFTER CAREFUL CONSIDERATION, THE BOARD OF TRUSTEES OF THE TRUST, INCLUDING THOSE TRUSTEES WHO ARE NOT “INTERESTED PERSONS” (AS THAT TERM IS DEFINED IN THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED) RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL.

Q: WHOM DO I CALL FOR MORE INFORMATION?

A: Please call [SOLICITOR] (“[SOLICITOR]”), the Acquired Portfolio’s proxy solicitor, at [ ].

Q: HOW CAN I VOTE MY SHARES OF BENEFICIAL INTEREST?

A: Please choose one of the following options to vote your shares of beneficial interest:

· By mail, with the enclosed proxy card;

· Through the Internet, by using the Internet address located on your proxy card and following the instructions on the site;

· By touch-tone telephone, with a toll-free call to the telephone number that appears on your proxy card;

· By faxing the enclosed proxy card to [SOLICITOR], Attn: [ ] at [ ]; or

· In person at the Special Meeting.

Q: WILL THE ACQUIRED PORTFOLIO PAY FOR THIS PROXY SOLICITATION?

A: No. Credit Suisse or its affiliates will bear the costs associated with approving the Agreement.

The shareholders of the Acquired Portfolio are being asked to approve an Agreement and Plan of Reorganization (the “Agreement”) providing that (i) the Acquired Portfolio would transfer to Credit Suisse Trust – Small Cap Core I Portfolio (the “Acquiring Portfolio”) all of its assets in exchange for shares of the Acquiring Portfolio and the assumption by the Acquiring Portfolio of the Acquired Portfolio’s liabilities, (ii) such shares of the Acquiring Portfolio would be distributed to shareholders of the Acquired Portfolio in liquidation of the Acquired Portfolio, and (iii) the Acquired Portfolio would subsequently be terminated as a series of the Trust; and

2. To transact such other business as may properly come before the Special Meeting or any adjournment or adjournments thereof.

THE BOARD OF TRUSTEES OF THE TRUST UNANIMOUSLY
RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL.

The Trust, on behalf of its portfolios, offers its shares only to certain insurance companies (“Participating Insurance Companies”) for allocation to certain of their separate accounts established for the purpose of funding variable annuity contracts, variable life insurance contracts, and tax qualified pension and retirement plans. Under current law, the Participating Insurance Companies are required to solicit voting instructions from variable annuity contract owners who beneficially own shares in the Acquired Portfolio as of the record date and must vote all shares held in the separate account in proportion to the voting instructions received for the Special Meeting, or any adjournment thereof.

If you hold shares through a variable annuity contract or a variable life insurance policy, and if you do not give specific voting instructions for your shares, they may not be voted at all or, as described above, they may be voted in a manner that you may not intend. Therefore, you are strongly encouraged to give your Participating Insurance Company specific instructions as to how you want your shares to be voted.

The Board of Trustees of the Trust has fixed the close of business on [ ], 2007 (the “Record Date”) as the record date for the determination of shareholders of the Acquired Portfolio entitled to notice of and to vote at the Special Meeting and any adjournment or adjournments thereof. As a convenience to shareholders, you can now vote in any one of five ways:

· By mail, with the enclosed proxy card;

· Through the Internet, by using the Internet address located on your proxy card and following the instructions on the site;

· By touch-tone telephone, with a toll-free call to the telephone number that appears on your proxy card;

· By faxing the enclosed proxy card to [SOLICITOR], Attn: [ ] at [ ]; or

· In person at the Special Meeting.

If you have any questions regarding the proposal, please feel free to call [SOLICITOR] at [NUMBER].

SHAREHOLDERS WHO DO NOT EXPECT TO ATTEND THE SPECIAL MEETING ARE URGED TO VOTE THROUGH A METHOD INDICATED ABOVE, SO THAT THEIR SHARES OF BENEFICIAL INTEREST MAY BE REPRESENTED AT THE SPECIAL MEETING. INSTRUCTIONS FOR THE PROPER EXECUTION OF PROXY CARDS ARE SET FORTH ON THE FOLLOWING PAGE. PROXIES MAY BE REVOKED AT ANY TIME BEFORE THEY ARE EXERCISED BY THE SUBSEQUENT EXECUTION AND SUBMISSION OF A REVISED PROXY, BY GIVING WRITTEN NOTICE OF REVOCATION TO THE ACQUIRED PORTFOLIO AT ANY TIME BEFORE THE PROXY IS EXERCISED OR BY VOTING IN PERSON AT THE SPECIAL MEETING.

IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY.

By Order of the Board of Trustees,

ELEVEN MADISON AVENUE
NEW YORK, NEW YORK 10010
1-800-[NUMBER]

This Prospectus/Proxy Statement is being furnished to shareholders of Credit Suisse Trust – Small Cap Core II Portfolio (the “Acquired Portfolio”), a series of Credit Suisse Trust (the “Trust”), an open-end, diversified management investment company organized as a Massachusetts business trust, in connection with the solicitation of proxies by the Trust’s Board of Trustees, on behalf of its Acquired Portfolio, for use at a Special Meeting of Shareholders to be held on [ ], 2007 at [ ] [a.m./p.m.] (the “Special Meeting”), at the offices of the Acquired Portfolio located at Eleven Madison Avenue, 24th Floor, New York, New York 10010, or any adjournment(s) thereof. The only proposal to be considered is set forth below:

1. To approve an Agreement and Plan of Reorganization (the “Agreement”).

Pursuant to the Agreement, the Acquired Portfolio would transfer to Credit Suisse Trust – Small Cap Core I Portfolio (the “Acquiring Portfolio” and together with the Acquired Portfolio, the “Portfolios”), also a series of the Trust, all of the Acquired Portfolio’s assets in exchange for shares of the Acquiring Portfolio and the assumption by the Acquiring Portfolio of the Acquired Portfolio’s liabilities; such shares of the Acquiring Portfolio would be distributed to shareholders of the Acquired Portfolio in liquidation of the Acquired Portfolio; and the Acquired Portfolio would subsequently be terminated as a series of the Trust (the “Acquisition”).

PROPOSAL - APPROVAL OF THE AGREEMENT

SUMMARY

THIS SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE ADDITIONAL INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS/PROXY STATEMENT, THE AGREEMENT (A COPY OF THE FORM OF THE AGREEMENT IS ATTACHED TO THIS PROSPECTUS/PROXY STATEMENT AS EXHIBIT A), THE PROSPECTUSES OF THE ACQUIRED PORTFOLIO, THE STATEMENT OF ADDITIONAL INFORMATION OF THE ACQUIRED PORTFOLIO, THE PROSPECTUS OF THE ACQUIRING PORTFOLIO AND THE STATEMENT OF ADDITIONAL INFORMATION OF THE ACQUIRING PORTFOLIO.

PROPOSED ACQUISITION. The Agreement provides for the acquisition of all of the assets and liabilities of the Acquired Portfolio by the Acquiring Portfolio in exchange for shares of the Acquiring Portfolio. The Agreement also calls for the distribution of shares of the Acquiring Portfolio to the Acquired Portfolio’s shareholders in liquidation of the Acquired Portfolio. As a result of the Acquisition, each shareholder of shares of beneficial interest of the Acquired Portfolio will become the owner of that number of full and fractional shares of the Acquiring Portfolio, having an aggregate net asset value (“NAV”) equal to the aggregate net asset value of such shareholder’s shares of beneficial interest in the Acquired Portfolio as of the close of business on the date that the Acquired Portfolio’s assets and liabilities are exchanged for shares of the Acquiring Portfolio. See “Information About the Acquisition - Agreement and Plan of Reorganization.”

Because the Portfolios are series of the Trust, they do not have a Board of Trustees separate from the other series of the Trust. Accordingly, when we refer to the “Board of Trustees of the Acquired Portfolio” and the “Board of Trustees of the Acquiring Portfolio” elsewhere in this Prospectus/Proxy Statement, we mean the Trustees and Board of Trustees of the Trust. For ease of reference and clarity of presentation, shares of beneficial interest of the Portfolios are hereinafter referred to as “shares,” and the term “shareholder” shall also be deemed to include holders of variable annuity contracts, variable life insurance policies and tax qualified pension and retirement plans.

For the reasons set forth below under “Reasons for the Acquisition,” the Board of Trustees of the Acquired Portfolio, including the Trustees of the Acquired Portfolio who are not “interested persons” (the “Independent Trustees”), as that term is defined in the Investment Company Act of 1940, as amended (the “1940 Act”), has unanimously concluded that the Acquisition would be in the best interests of its shareholders and that the interests of its existing shareholders will not be diluted as a result of the transaction contemplated by the Acquisition. The Board of Trustees of the Acquired Portfolio therefore has submitted the Agreement for approval by its shareholders. The Board of Trustees of the Acquiring Portfolio has also reached similar conclusions and approved the Acquisition with respect to the Acquiring Portfolio.

series of the Trust. In the event the Agreement is not approved, the Board of Trustees of the Acquired Portfolio will consider other possible courses of action available to it, including resubmitting the Acquisition proposal to shareholders.

If the Acquisition is approved, upon closing the name of the Acquiring Portfolio will change from Credit Suisse Trust—Small Cap Core I Portfolio to Credit Suisse Trust—Small Cap Core Portfolio.

TAX CONSEQUENCES. Prior to completion of the Acquisition, the Acquired Portfolio and the Acquiring Portfolio will have received an opinion of counsel that, as a result of the Acquisition, no gain or loss will be recognized by the shareholders of the Acquired Portfolio for federal income tax purposes and generally the Acquired Portfolio will not recognize gain or loss for such purposes. The holding period and aggregate tax basis of the Acquiring Portfolio shares received by an Acquired Portfolio shareholder will be the same as the holding period and aggregate tax basis of the shares of beneficial interest of the Acquired Portfolio exchanged therefor by such shareholder. In addition, the holding period and aggregate tax basis of the assets of the Acquired Portfolio in the hands of the Acquiring Portfolio as a result of the Acquisition, will generally be the same as in the hands of the Acquired Portfolio immediately prior to the Acquisition.

INVESTMENT OBJECTIVES AND POLICIES. As noted and further described in the attached Prospectus/Proxy Statement, there are no material differences between the investment objectives and policies of the Portfolios.

The investment objective of the Acquiring Portfolio is capital growth. The investment objective of the Acquired Portfolio is high level of growth of capital.

Both Portfolios have substantially similar primary investments. Each portfolio invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of small U.S. companies. These securities are selected using proprietary quantitative stock selection models.

Each Portfolio is managed by a team that employs quantitative portfolio management techniques rather than a traditional fundamental equity research approach. The portfolio managers select securities for each Portfolio using proprietary quantitative models, which are designed to:

· forecast the expected relative return of stocks by analyzing a number of fundamental factors, including a company’s relative valuation, use of capital, balance sheet quality, profitability, realized and expected growth potential and earnings and price momentum;

· identify stocks that are likely to suffer declines in price if market conditions deteriorate and limit a Portfolio’s overall exposure to such low quality stocks; and

· help determine a Portfolio’s relative exposure to different industry sectors by analyzing sector performance under different market scenarios.

Under each Portfolio’s investment strategy, the portfolio managers will apply the proprietary quantitative models described above to companies that are represented in the Standard & Poor’s SmallCap 600® Index (the “S&P 600 Index”), as well as other companies with similar attributes and capitalizations to the companies in the S&P 600 Index.

Each Portfolio may invest in common and preferred stocks, securities convertible into common stocks, rights and warrants, special-situation companies, start-up and other small companies, investment grade debt securities including U.S. government and municipal and other financial instruments.

PURCHASE, REDEMPTION AND EXCHANGE PROCEDURES. You may not buy or sell shares of a Portfolio directly; you may only buy or sell shares through variable annuity contracts and variable life insurance contracts offered by separate accounts of certain insurance companies or through tax-qualified pension and retirement plans. A Portfolio may not be available in connection with a particular contract or plan.

An insurance company’s separate accounts buy and sell shares of a Portfolio at NAV, without any sales or other charges. Each insurance company receives orders from its contract holders to buy or sell shares of the Portfolio on any business day that the portfolio calculates its NAV. If the order is received by the insurance company prior to the close of regular trading on the NYSE, the order will be executed at that day’s NAV.

Plan participants may buy shares of the portfolio through their plan by directing the plan trustee to buy shares for their account in a manner similar to that described above for variable annuity and variable life insurance contracts. You should contact your plan sponsor concerning the appropriate procedure for investing in a Portfolio.

DIVIDENDS. The Acquiring Portfolio and the Acquired Portfolio distribute substantially all of their respective net investment income and net realized capital gains, if any, to their respective shareholders. All distributions are reinvested in the form of additional full and fractional shares of the Portfolio unless a shareholder elects otherwise. Each Portfolio typically declares and pays dividends, if any, from net investment income at least annually. Net realized capital gains, if any, of each Portfolio are typically distributed at least annually. The Acquired Portfolio will pay a dividend of undistributed net investment income and capital gains, if any, immediately prior to the Closing Date. The amount of any dividend actually paid prior to the Closing Date will vary depending on a number of factors, such as changes in the value of the Acquired Portfolio’s holdings and net redemptions of the Acquired Portfolio’s shares of beneficial interest. If determined as of [ ], 2006, the Acquired Portfolio would have distributed $[ ] or $[ ] per share. See “Dividend and Distribution Information” in the accompanying Prospectus of the Acquiring Portfolio.

APPRAISAL RIGHTS. Under the laws of the Commonwealth of Massachusetts, shareholders of the Acquired Portfolio do not have appraisal rights in connection with a combination or acquisition of the assets of the Acquired Portfolio by another entity. See “Information on Shareholders’ Rights - Voting Rights.”

RISK FACTORS

The principal risk factors of both Portfolios are identical. They are as follows:

MARKET RISK The market value of a security may fluctuate, sometimes rapidly and unpredictably. These fluctuations, which are often referred to as “volatility,” may cause a security to be worth less than it was worth at an earlier time. Market risk may affect a single issuer, industry, sector of the economy, or the market as a whole. Market risk is common to most investments–including stocks and bonds, and the mutual funds that invest in them.

SPECIAL-SITUATION COMPANIES “Special situations” are unusual developments that affect a company’s market value. Examples include mergers, acquisitions and reorganizations. Securities of special-situation companies may decline in value if the anticipated benefits of the special situation do not materialize.

START-UP AND OTHER SMALL COMPANIES Start-up and other small companies may have less-experienced management, limited product lines, unproven track records or inadequate capital reserves. Their securities may carry increased market, liquidity, information and other risks. Key information about the company may be inaccurate or unavailable.

The Acquired Portfolio has greater exposure to the risks of investing in foreign securities than the Acquiring Portfolio as the Acquired Portfolio may invest up to 20% of its net assets in foreign securities, while the Acquiring Portfolio may invest up to 10% of its total assets in such securities. The Acquiring Portfolio has greater exposure to the risks of investing in options than the Acquired Portfolio as the Acquiring Portfolio may invest up to 25% of its total assets in options, while the Acquired Portfolio may invest up to 10% of its total assets in such securities. The Acquired Portfolio has greater exposure to the risks of investing in short sales than the Acquiring Portfolio as the Acquired Portfolio may invest up to 10% of its net assets in short sales, while the Acquiring Portfolio is permitted, but not expected, to invest to a significant extent in such securities. See the accompanying Prospectus of the Acquiring Portfolio for a complete discussion of the risks of investing in the Acquiring Portfolio.

FEE TABLES

Following are two tables showing expected fees and expenses for the fiscal year ending December 31, 2006 of the Acquired Portfolio, holders of which will receive shares of the Acquiring Portfolio, and the expected fees and expenses for the fiscal year ending December 31, 2006 of the Acquiring Portfolio before and after giving effect to the Acquisition. These tables do not reflect fees and expenses incurred at the variable product or plan level; if they were reflected, the overall costs would be higher.

EXAMPLES

The following examples are intended to assist an investor in understanding the various costs that an investor in each Portfolio will bear directly or indirectly. The examples assume payment of operating expenses at the levels set forth in the tables presented above (in each case before fee waivers and expense reimbursements) and that all dividends and distributions are reinvested. The examples also assume that you invest $10,000 in the Portfolios for the time periods indicated and then redeem all of your shares at the end of those periods. The examples also assume that your investment has a 5% return each year and that the Portfolios’ operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

ACQUIRED PORTFOLIO

ACQUIRING PORTFOLIO

COMBINED PORTFOLIO PRO FORMA

REASONS FOR THE ACQUISITION

The Board of Trustees of the Acquired Portfolio has unanimously determined that it is in the best interest of the Acquired Portfolio to effect the Acquisition. In reaching this conclusion, the Board considered a number of factors, including the following:

1. the Acquisition will result in a single larger portfolio seeking capital growth through equity securities of small companies;

2. effective management fees are not expected to increase as a result of the Acquisition; however, the management fee structure of the Acquired Portfolio currently has a breakpoint structure in place while the Acquiring Portfolio has no such structure. Should the Acquired Portfolio reach certain breakpoints its management fee would potentially be lower than that charged by the Acquiring Fund, however, the Acquired Portfolio has not reached, nor is anticipated to reach at any time in the near future, such breakpoints.

3 total expenses gross and net of waivers and reimbursements are expected to decline as a result of the Acquisition;

4. the Acquisition will eliminate any confusion in the marketplace associated with having two portfolios managed by Credit Suisse investing in small capitalization securities;

5. the Acquisition should increase efficiencies, eliminating one of the two sets of prospectuses, reports to shareholders and other documents required if the Acquired and

Acquiring Portfolios remained separate, although there is no guarantee that the combined portfolio will realize such efficiencies;

6. the terms and conditions of the Acquisition;

7. the larger combined asset base could produce portfolio management benefits, such as the ability to command more attention from brokers and underwriters of securities in which the Portfolios invest than either Portfolio currently enjoys, although the primary beneficiary will be the Acquiring Portfolio;

8. that the investment adviser for the Acquiring Portfolio is the same as that of the Acquired Portfolio;

9. the federal tax consequences of the Acquisition, and that a legal opinion will be rendered that no gain or loss will be recognized by the shareholders of the Acquired Portfolio or by the Acquiring Portfolio for federal income tax purposes as a result of the Acquisition and that the Acquired Portfolio generally will not recognize gain or loss for such purposes;

10. that the interests of shareholders of the Acquired Portfolio will not be diluted as a result of the Acquisition;

11. that the expenses of the Acquisition will be borne by Credit Suisse or its affiliates; and

12. that no sales or other charges will be imposed in connection with the Acquisition.

The Board also noted that the Acquisition will result in the combined portfolio having a total capital loss carry over of approximately $78 million; all of which was maintained, prior to the Acquisition, by the Acquiring Portfolio. Of this $78 million, $73 million will expire in 2010 and $5 million will expire in 2011.

In light of the foregoing, the Board of Trustees of the Acquired Portfolio, including the Independent Trustees, has determined that it is in the best interests of the Acquired Portfolio and its shareholders to effect the Acquisition. The Board of Trustees of the Acquired Portfolio has also determined that the Acquisition would not result in dilution of the interests of the Acquired Portfolio’s shareholders. In making these determinations, the Board of Trustees did not give equal weight to each factor.

The Board of Trustees of the Acquiring Portfolio has determined that it is advantageous to the Acquiring Portfolio to effect the Acquisition. The Board of Trustees of the Acquiring Portfolio considered, among other things, the terms and conditions of the Acquisition and representations that the Acquisition would be effected as a tax-free reorganization. Accordingly, the Board of Trustees of the Acquiring Portfolio, including a majority of the Independent Trustees, has determined that the Acquisition is in the best interests of the Acquiring Portfolio’s shareholders and that the interests of the Acquiring Portfolio’s shareholders would not be diluted as a result of the Acquisition.

INFORMATION ABOUT THE ACQUISITION

AGREEMENT AND PLAN OF REORGANIZATION. The following summary of the Agreement is qualified in its entirety by reference to the form of the Agreement (Exhibit A hereto). The Agreement provides that the Acquiring Portfolio will acquire all of the assets of the Acquired Portfolio in exchange for shares of the Acquiring Portfolio and the assumption by the Acquiring Portfolio of the

liabilities of the Acquired Portfolio on the Closing Date. The Closing Date is expected to be on or about [ ], 2007.

Prior to the Closing Date, the Acquired Portfolio will endeavor to discharge all of its known liabilities and obligations, other than those liabilities and obligations which would otherwise be discharged at a later date in the ordinary course of business. The Acquiring Portfolio will assume all liabilities, expenses, costs, charges and reserves, including those liabilities reflected on an unaudited statement of assets and liabilities for the Acquired Portfolio, as of the close of regular trading on The New York Stock Exchange, Inc. (“NYSE”), currently [ ] [a.m./p.m.], New York City time, on the Closing Date, in accordance with generally accepted accounting principles consistently applied from the prior audited period. The NAV per share of each Portfolio will be calculated by determining the total assets attributable to such Portfolio, subtracting the Portfolio’s actual and accrued liabilities, and dividing the result by the total number of outstanding shares. Each Portfolio will utilize the procedures set forth in its respective current Prospectuses or Statement of Additional Information to determine the value of its respective portfolio securities and to determine the aggregate value of each Portfolio’s portfolio.

On or as soon after the Closing Date as conveniently practicable, the Acquired Portfolio will liquidate and distribute pro rata to shareholders of record as of the close of business on the Closing Date the shares of the Acquiring Portfolio received by the Acquired Portfolio. Such liquidation and distribution will be accomplished by the establishment of accounts in the names of the Acquired Portfolio’s shareholders on the share records of the Acquiring Portfolio’s transfer agent. Each account will represent the number of shares of the Acquiring Portfolio due to the Acquired Portfolio’s shareholders calculated in accordance with the Agreement. After such distribution and the winding up of its affairs, the Acquired Portfolio will terminate as a series of the Trust.

The consummation of the Acquisition is subject to the conditions set forth in the Agreement, including approval of the Agreement by the Acquired Portfolio’s shareholders. Notwithstanding approval by the shareholders of the Acquired Portfolio, the Agreement may be terminated at any time at or prior to the Closing Date upon the vote of a majority of the Board of Trustees of the Trust.

Pursuant to the Agreement, the Acquiring Portfolio has agreed to indemnify and advance expenses to each Trustee or officer of the Acquired Portfolio against money damages incurred in connection with any claim arising out of such person’s services as a Trustee or officer with respect to matters specifically relating to the Acquisition, except by reason of such person’s willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties in the conduct of his or her office.

Approval of the Agreement requires the affirmative vote of a majority of the outstanding shares of the Acquired Portfolio, present in person or represented by proxy. Shareholders of the Acquired Portfolio are entitled to one vote for each share of beneficial interest and a fractional vote for each fraction share of beneficial interest. If shareholders of the Acquired Portfolio approve the Acquisition, the Acquired Portfolio will be liquidated upon consummation of the Acquisition and subsequently terminated as a series of the Trust. In the event the Agreement is not approved, the Board of Trustees of the Acquired Portfolio will consider other possible courses of action available to it, including resubmitting the Acquisition proposal to shareholders.

DESCRIPTION OF THE ACQUIRING PORTFOLIO SHARES. Shares of the Acquiring Portfolio will be issued to the Acquired Portfolio in accordance with the procedures detailed in the Agreement and as described in the Acquiring Portfolio’s Prospectus and Statement of Additional Information. The Acquiring Portfolio, like the Acquired Portfolio, will not issue share certificates to its shareholders. See “Information on Shareholders’ Rights” and the Prospectus of the Acquiring Portfolio for additional information with respect to the shares of the Acquiring Portfolio.

FEDERAL INCOME TAX CONSEQUENCES. The closing of the Acquisition is conditioned upon the receipt by the Portfolios of an opinion from Willkie Farr & Gallagher LLP, counsel to the Portfolios, to the effect that, based upon certain facts, assumptions and representations, the Acquisition will constitute a tax-free reorganization within the meaning of section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). If the Acquisition constitutes a tax-free reorganization, no gain or loss will be recognized by the Acquired Portfolio shareholders as a result of their exchange of shares of beneficial interest pursuant to the Acquisition and no gain or loss will generally be recognized by the Acquired Portfolio and the Acquiring Portfolio as a result of the Acquisition. This opinion, in substance, will state that for U.S. federal income tax purposes:

(a) The transfer of all of the Acquired Portfolio’s assets to the Acquiring Portfolio in exchange for the Acquiring Portfolio Shares and the assumption by the Acquiring Portfolio of the liabilities of the Acquired Portfolio, followed by the distribution by the Acquired Portfolio of such Acquiring Portfolio Shares to shareholders of the Acquired Portfolio in complete liquidation of the Acquired Portfolio, all pursuant to the Agreement, will constitute a “reorganization” within the meaning of Section 368(a) of the Code, and the Acquiring Portfolio and the Acquired Portfolio will each be a “party to a reorganization” within the meaning of Section 368(b) of the Code;

(b) no gain or loss will be recognized by the Acquiring Portfolio on the receipt of the assets of the Acquired Portfolio solely in exchange for the Acquiring Portfolio Shares and the assumption by the Acquiring Portfolio of the liabilities of the Acquired Portfolio;

(c) except for gain or loss regularly attributable to the termination of the Acquired Portfolio’s taxable year, no gain or loss will be recognized by the Acquired Portfolio upon the transfer of the Acquired Portfolio’s assets to the Acquiring Portfolio in exchange for the Acquiring Portfolio Shares and the assumption by the Acquiring Portfolio of the liabilities of the Acquired Portfolio or upon the distribution of the Acquiring Portfolio Shares to the Acquired Portfolio’s shareholders in exchange for their shares of the Acquired Portfolio;

(d) no gain or loss will be recognized by shareholders of the Acquired Portfolio upon the exchange of their Acquired Portfolio shares of beneficial interest for the Acquiring Portfolio Shares or upon the assumption by the Acquiring Portfolio of the liabilities of the Acquired Portfolio pursuant to the Agreement;

(e) the aggregate tax basis of the Acquiring Portfolio Shares received by each of the Acquired Portfolio’s shareholders pursuant to the Acquisition will be the same as the aggregate tax basis of the Acquired Portfolio shares of beneficial interest held by such shareholder immediately prior to the Acquisition, and the holding period of the Acquiring Portfolio Shares to be received by each Acquired Portfolio shareholder will include the period during which the Acquired Portfolio shares of beneficial interest exchanged therefor were held by such shareholder (provided that such Acquired Portfolio shares of beneficial interest were held as capital assets on the date of the Acquisition); and

(f) except for assets which may be revalued as a consequence of a termination of the Acquired Portfolio’s taxable year, the tax basis of the Acquired Portfolio’s assets acquired by the Acquiring Portfolio will be the same as the tax basis of such assets to the Acquired Portfolio immediately prior to the Acquisition and the holding period of the assets of the Acquired Portfolio in the hands of the Acquiring Portfolio will include the period during which those assets were held by the Acquired Portfolio.

You should recognize that an opinion of counsel is not binding on the Internal Revenue Service (“IRS”) or any court. Neither the Acquired Portfolio nor the Acquiring Portfolio will seek to obtain a ruling from the IRS regarding the tax consequences of the Acquisition. Accordingly, if the IRS sought to

challenge the tax treatment of the Acquisition and was successful, neither of which is anticipated, the Acquisition could be treated, in whole or in part, as a taxable sale of assets of the Acquired Portfolio, followed by the taxable liquidation thereof.

The Acquiring Portfolio intends to continue to be taxed under the rules applicable to regulated investment companies as defined in Section 851 of the Code, which are the same rules currently applicable to the Acquired Portfolio and its shareholders.

Prior to the Closing Date, the Acquired Portfolio will declare a distribution to its shareholders, if any, which together with all previous distributions, will have the effect of distributing to its shareholders all of its investment company taxable income (computed without regard to the deduction for dividends paid) and net realized capital gains, if any, through the Closing Date.

The Acquiring Portfolio’s capital loss carryforwards if any should not be limited solely by reason of the Reorganization. However, for five years beginning after the Closing Date of the Acquisition, the combined portfolio will not be allowed to offset certain pre-Acquisition built-in gains attributable to the Acquired Portfolio with the capital loss carryforwards (and certain built-in losses) attributable to Acquiring Portfolio.

Shareholders of the Acquired Portfolio should consult their tax advisors regarding the effect, if any, of the proposed Acquisition in light of their individual circumstances. Since the foregoing discussion only relates to the U.S. federal income tax consequences of the Acquisition, shareholders of the Acquired Portfolio should also consult their tax advisors as to state, local and foreign tax consequences, if any, of the Acquisition.

TOTAL RETURNS

The bar chart below and the table on the next page provide an indication of the risks of investing in each Portfolio. The bar chart shows you how each Portfolio’s performance has varied from year to year for up to 10 years. The table compares each Portfolio’s performance over time to that of a broad-based securities market index. The bar chart and table do not reflect additional charges and expenses which are, or may be, imposed under the variable contracts or plans; such charges and expenses are described in the prospectus of the insurance company separate account or in the plan documents or other informational materials supplied by plan sponsors. Inclusion of these charges and expenses would reduce the total return for the periods shown. As with all mutual funds, past performance is not a prediction of future performance.

OWNERSHIP OF THE PORTFOLIOS

All shares of the Acquired Portfolio and the Acquiring Portfolio are owned of record by Participating Insurance Company separate accounts for the benefit of contract owners. [No contract owner had, as of the Record

Date, voting authority over as much as 5% of any Portfolios’ shares.] The insurance company separate accounts that own shares of the Portfolios do not have an economic interest in the Portfolios.

Listed below are the name, address and share ownership of each person known to the Trust to own 5% or more of the shares of the Acquired Portfolio and the Acquiring Portfolio as of the Record Date. The table also indicates the percentage of each Portfolio’s shares to be owned by such persons upon consummation of the Acquisition on the basis of present holdings and commitments. The type of ownership of each person listed below is record ownership.

COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES

The following discussion is based upon and qualified in its entirety by the disclosure in the respective Prospectuses and Statements of Additional Information of the Acquiring Portfolio and the Acquired Portfolio.

INVESTMENT OBJECTIVES. There are no material differences between the investment objectives of the Portfolios. The Acquiring Portfolio’s investment objective is capital growth while the Acquired Portfolio’s is a high level of growth of capital. There can be no assurance either Portfolio will achieve its investment objective.

PRIMARY INVESTMENTS. Both portfolios have substantially similar primary investments. Each portfolio invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of small U.S. companies. These securities are selected using proprietary quantitative stock selection models.

· identify stocks that are likely to suffer declines in price if market conditions deteriorate and limit a Portfolio’s overall exposure to such low quality stocks; and

· help determine a Portfolio’s relative exposure to different industry sectors by analyzing sector performance under different market scenarios.

Under each Portfolio’s investment strategy, the portfolio managers will apply the proprietary quantitative models described above to companies that are represented in the S&P 600 Index, as well as other companies with similar attributes and capitalizations to the companies in the S&P 600 Index. A stock may be overweighted or underweighted in relation to the S&P 600 Index based on the expected return and risks associated with that stock, both considered relative to the Portfolio as a whole, among other characteristics. In general, the Portfolio will maintain investment attributes that are similar to those of the S&P 600 Index, and intends to limit its divergence from the S&P 600 Index in terms of market, industry and sector exposures.

Each Portfolio may invest in:

· Common and preferred stocks

· Securities convertible into common stocks

· Rights and warrants

· Special-situation companies

· Start-up and other small companies

· Investment grade debt securities including U.S. government and municipal and other financial instruments

Each Portfolio may invest up to 20% of its net assets in debt securities, including up to 5% of its net assets in non-investment-grade debt securities. The Acquired Portfolio may invest up to 20% of its net assets in foreign securities, while the Acquired Portfolio may invest up to 10% of its total assets in foreign securities. The Acquiring Portfolio may invest up to 25% of its total assets in options, while the Acquired Portfolio may invest up to 10% of its total assets in such securities. The Acquired Portfolio may invest up to 10% of its net assets in short sales, while the Acquiring Portfolio is permitted, but not expected, to invest to a significant extent in such securities. The Acquired Portfolio may invest in unlisted securities and securities traded over-the-counter.

INVESTMENT LIMITATIONS. The Acquiring Portfolio and the Acquired Portfolio have adopted certain fundamental and non-fundamental investment limitations. Fundamental investment limitations may not be changed without the affirmative vote of the holders of a majority of the outstanding voting securities of the relevant Portfolio. Each Portfolio has substantially similar fundamental investment limitations.

CERTAIN INVESTMENT PRACTICES. For each of the following practices, this table shows the current applicable investment limitation. Risks are indicated for each practice. The specific risks associated with each of the investment practices described below are defined for the Acquiring Portfolio in the Acquiring Portfolio’s Prospectus, which accompanies this Prospectus/Proxy Statement, and for the Acquired Portfolio in its Prospectuses.

(1) Each Portfolio is not obligated to pursue any hedging strategy. In addition, hedging practices may not be available, may be too costly to be used effectively or may be unable to be used for other reasons.

(2) Each Portfolio is limited to 5% of net assets for initial margin and premium amounts on futures positions considered to be speculative.

DETERMINATION OF NET ASSET VALUE OF SHARES OF THE ACQUIRING PORTFOLIO

The NAV is determined at the close of regular trading on the New York Stock Exchange (“NYSE”) (usually 4 p.m. ET) each day the NYSE is open for business. It is calculated by dividing the Portfolio’s total assets, less its liabilities, by the number of shares outstanding.

The Portfolio’s equity investments are valued at market value, which is generally determined using the closing price on the exchange or market on which the security is primarily traded at the time of valuation (the “Valuation Time”). If no sales are reported, equity investments are generally valued at the most recent bid quotation as of the Valuation Time or at the lowest asked quotation in the case of a short sale of securities. Debt securities with a remaining maturity greater than 60 days are valued in accordance with the price supplied by a pricing service, which may use a matrix, formula or other objective method that takes into consideration market indices, yield curves and other specific adjustments. Debt obligations that will mature in 60 days or less are valued on the basis of amortized cost, which approximates market value, unless it is determined that this method would not represent fair value. Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation. Securities and other assets for which market quotations are not readily available, or whose values have been materially affected by events occurring before the Portfolio’s Valuation Time but after the close of the securities’ primary markets, are valued at fair value as determined in good faith by, or under the direction of, the Board of Trustees under procedures established by the Board of Trustees. The Portfolio may utilize a service provided by an independent third party which has been approved by the Board of Trustees to fair value certain securities.

The Portfolio’s fair valuation policies are designed to reduce dilution and other adverse effects on long-term shareholders of trading practices that seek to take advantage of “stale” or otherwise inaccurate prices. When fair value pricing is employed, the prices of securities used by the Portfolio to calculate its NAV may differ from quoted or published prices for the same securities. Valuing securities at fair value involves greater reliance on judgment than valuation of securities based on readily available market quotations. A Portfolio that uses fair value to price securities may value those securities higher or lower than another fund using market quotations or its own fair value procedures to price the same securities.

There can be no assurance that the Portfolio could obtain the fair value assigned to a security if it were to sell the security at approximately the time at which the Portfolio determines its NAV.

Some Portfolio securities may be listed on foreign exchanges that are open on days (such as U.S. holidays) when the Portfolio does not compute its prices. This could cause the value of the Portfolio’s investments to be affected by trading on days when you cannot buy or sell shares.

Frequent purchases and redemptions of Portfolio shares present risks to the contract owners or plan participants who hold shares of a Portfolio through their annuity contracts or pension plans over the long term. These risks include the potential for dilution in the value of Portfolio shares; interference with the efficient management of the Portfolio, such as the need to keep a larger portion of the Portfolio invested in cash or short-term securities, or to sell securities, rather than maintaining full investment in securities selected to achieve the Portfolio’s investment objective; losses on the sale of investments resulting from the need to sell securities at less favorable prices; and increased brokerage and administrative costs. These risks may be greater for Portfolios investing in securities that are believed to be more susceptible to pricing discrepancies, such as foreign securities, high yield debt securities and small capitalization securities, as certain investors may seek to make short-term trades as part of strategies aimed at taking advantage of “stale” or otherwise inaccurate prices for Portfolio holdings (e.g., “time zone arbitrage”).

Each Portfolio will take steps to detect and eliminate excessive trading in Portfolio shares, pursuant to the Portfolio’s policies approved by the Board of Trustees. Each Portfolio defines excessive trading or “market timing” as two round trips (purchase and redemption of comparable assets) by an investor within 60 days. A contract owner or plan participant that is determined to be engaged in market timing will be restricted from making future purchases or exchange purchases in any of the Credit Suisse Funds. Each Portfolio’s shares are offered exclusively to insurance company separate accounts that fund certain insurance contracts, or to tax-qualified pension and retirement plans. These shareholders typically hold Portfolio shares for a number of contracts or participants in a single account. Each Portfolio’s distributor enters into agreements with Participating Insurance Companies that require such companies to provide certain information to help detect frequent trading by their contract owners or plan participants and to eliminate frequent trading by such owners and participants. It should also be noted that insurance company separate accounts and plans may have their own policies and procedures to detect and prevent excessive trading in shares of the underlying mutual funds they offer, which may define market timing differently than the Portfolio does and have different consequences associated with it.

The Portfolio reserves the right to reject a purchase or exchange purchase order for any reason with or without prior notice to the insurance contract or plan. In particular, the Portfolio reserves the right to reject a purchase or an exchange purchase order from any insurance contract or plan that in its opinion has not taken effective steps to detect and prevent frequent purchases and sales of Portfolio shares.

The Portfolio has also adopted fair valuation policies to protect the Portfolio from “time zone arbitrage” with respect to foreign securities holdings and other trading practices that seek to take advantage of “stale” or otherwise inaccurate prices.

The Portfolio’s policies and procedures may be modified or terminated at any time upon notice of material changes to shareholders and prospective investors.

MANAGEMENT OF EACH PORTFOLIO

Credit Suisse, located at Eleven Madison Avenue, 24th Floor, New York, New York 10010, provides investment advisory services to each of the Portfolios under separate advisory agreements. Credit Suisse is part of the asset management business of Credit Suisse (“CS”), one of the world’s leading banks. CS provides its clients with investment banking, private banking and asset management services worldwide. The asset management business of CS is comprised of a number of legal entities around the world that are subject to distinct regulatory requirements.

The Credit Suisse Quantitative Strategies Group (see biographies below) is responsible for the day-to-day portfolio management of the Portfolios. The group currently consists of Joseph Cherian, William Weng and Todd Jablonski. Mr. Cherian and Mr. Weng are the lead managers of the Credit Suisse Quantitative Strategies Group.

JOSEPH CHERIAN, Managing Director, is Global Head of the Quantitative Strategies Group. Prior to joining Credit Suisse, Mr. Cherian was at Banc of America Capital Management from 2000 to 2004, where he was a Managing Director responsible for managing numerous asset allocation funds and quantitative equity products, as well as quantitative research used by Bank of America’s active equities and private bank divisions. Previously, he was an associate professor of finance at Boston University. Mr. Cherian holds a BS in Electrical Engineering from the Massachusetts Institute of Technology, and MS and PhD degrees in Finance from Cornell University. He is a review board member of the Research Foundation of the CFA Institute (AIMR).

WILLIAM WENG, Director, is a Senior Portfolio Manager in the Quantitative Strategies Group.

He is a CFA charterholder and is a member of the New York Society of Security Analysts and the Society of Quantitative Analysts.

Each Portfolio’s Statement of Additional Information provides additional information about the portfolio managers’ compensation, other accounts managed by the portfolio managers and the portfolio managers’ ownership of securities in the portfolio.

In addition, State Street and CSAMSI provide accounting and co-administrative services as applicable to each Portfolio. Boston Financial Data Services, Inc. acts as the shareholder servicing agent, transfer agent and dividend disbursing agent for each Portfolio. State Street serves as custodian of each of the Portfolios’ assets pursuant to a custodian agreement. [ ] serves as independent auditors for each of the Portfolios.

The Acquiring Portfolio pays Credit Suisse a management fee of 0.70% of its average daily net assets, while the Acquired Portfolio pays Credit Suisse a management fee of the lower of (1) 0.70%, or (2) 0.875% of its average daily net assets up to and including $100 million, 0.75% of its average daily net assets in excess of $100 million up to and including $200 million; and 0.50% of its average daily net assets in excess of $200 million. For the 2006 fiscal year, the Acquiring Portfolio and Acquired Portfolio each paid Credit Suisse [ ]% and [ ]%, respectively, of its average net assets for advisory services. Should the Acquired Portfolio reach certain breakpoints its management fee would potentially be lower than that charged by the Acquiring Fund, however, the Acquired Portfolio has not reached, nor is anticipated to reach at any time in the near future, such breakpoints.

In addition to the management fee, each Portfolio pays a co-administration fee to CSAMSI of 0.09% of its average daily net assets. Each Portfolio pays State Street a fee calculated at the annual rate of its pro-rated share of 0.05% of the first $5 billion in average daily net assets of the Credit Suisse Fund Complex (the “Fund Complex”), 0.035% of the Fund Complex’s next $5 billion in average daily net assets, and 0.02% of the Fund Complex’s average daily net assets in excess of $10 billion, exclusive of out-of-pocket expenses.

A discussion regarding the basis for the Board of Trustees’ approval of each investment advisory contract of each Portfolio is available in each Portfolio’s annual report to shareholders for the period ended December 31, 2006.

Each Portfolio bears its proportionate share of fees payable to Credit Suisse, CSAMSI and State Street in the proportion that its assets bear to the aggregate assets of the Portfolio at the time of calculation. These fees are calculated at an annual rate based on a percentage of a Portfolio’s average daily net assets.

INTEREST OF CREDIT SUISSE IN THE ACQUISITION

Credit Suisse may be deemed to have an interest in the Agreement and the Acquisition because it provides investment advisory services to each Portfolio. Credit Suisse receives compensation from each Portfolio for services it provides pursuant to separate advisory agreements. The terms and provisions of the current arrangements with Credit Suisse are described in each Portfolio’s Prospectuses and Statement of Additional Information. Future growth of the assets of the Acquiring Portfolio, if any, can be expected to increase the total amount of fees payable to Credit Suisse and its affiliates.

Credit Suisse may also be deemed to have an interest in the Agreement and the Acquisition because CSAMSI serves as the co-administrator and distributor for each Portfolio. As such, CSAMSI receives compensation for its services.

INFORMATION ON SHAREHOLDERS’ RIGHTS

GENERAL. The Trust was organized on March 15, 1995 under the laws of the Commonwealth of Massachusetts as a “Massachusetts business trust.” The Trust’s Declaration of Trust, as amended (the “Declaration of Trust”), authorizes the Board to issue an unlimited number of full and fractional shares of beneficial interest, $.001 par value per share.

In each Portfolio, shares represent interests in the assets of the relevant Portfolio and have identical voting, dividend, liquidation and other rights on the same terms and conditions.

TRUSTEES. The Declaration of Trust and the By-laws provide that the term of office of each Trustee shall be from the time of his or her election and qualification until his or her successor shall have been elected and shall be qualified or his earlier resignation, removal or death. The Trustees have the power to set and alter their terms of office, and at any time to lengthen or shorten their own terms or make their terms of unlimited duration. Trustees of the Portfolio may be removed by at least two-thirds of Trustees. Vacancies on the Board of the Trust may be filled by the Trustees remaining in office, provided that no vacancy or vacancies may be filled by action of the remaining Trustees if, after the filling of the vacancy or vacancies, fewer than two-thirds of the Trustees then holding office shall have been elected by the shareholders of the relevant Portfolio. A meeting of shareholders will be required for the purpose of electing Trustees whenever (a) fewer than a majority of the Trustees then in office were elected by shareholders of the relevant Portfolio or (b) a vacancy exists that may not be filled by the remaining Trustees and must be filled.

VOTING RIGHTS. When matters are submitted for shareholder vote, shareholders of each Portfolio will have one vote for each full share held and fractional votes for fractional shares held. Generally, shares of the Trust will vote by individual Portfolio on all matters except where otherwise required by law. There will normally be no meetings of shareholders for the purpose of electing Trustees unless and until such time as less than a majority of the members holding office have been elected by shareholders. Shareholders of record of no less than two-thirds of the outstanding shares of the Trust may remove a Trustee through a declaration in writing or by vote cast in person or by proxy at a meeting called for that purpose. A meeting will be called for the purpose of voting on the removal of a Trustee at the written request of holders of 10% of the Trust’s outstanding shares.

Under current law, a Participating Insurance Company is required to request voting instructions from variable contract owners and must vote all Portfolio shares held in the separate account in proportion to the voting instructions received. Plans may or may not pass through voting rights to plan participants, depending on the terms of the plan’s governing documents. For a more complete discussion of voting rights, refer to the sponsoring Participating Insurance Company separate account prospectus or the plan documents or other informational materials supplied by plan sponsors.

At least a majority of shares of beneficial interest of the Acquired Portfolio entitled to vote at a meeting will constitute a quorum.

LIQUIDATION OR TERMINATION. All shareholders of a Portfolio, upon liquidation, will participate ratably in the Portfolio’s net assets.

INVOLUNTARY REDEMPTIONS. The Trust’s Declaration of Trust authorizes each Portfolio to redeem shares of a series held by a shareholder, subject to applicable law, if the at any time, the Trustees determine in their sole discretion that such redemption is in the best interests of the holders of the shares of the Trust or of any Portfolio. Each Portfolio would provide prior notice of any plan to involuntarily redeem shares absent extraordinary circumstances. The exercise of the power granted to the Board under the Declaration of Trust is subject to the Board’s fiduciary obligation to the shareholders and any applicable provisions under the 1940 Act and the rules thereunder.

RIGHTS OF INSPECTION. Massachusetts business trust law does not have provisions relating to rights of inspection. However, the Acquired Portfolio’s Declaration of Trust provides that the records of the Acquired Portfolio shall be open to inspection by shareholders to the same extent as is permitted to stockholders of a corporation under the Massachusetts Business Corporation Law.

LIABILITY OF TRUSTEES. The Declaration of Trust provides that the Trustees and officers shall not be liable in such capacity for monetary damages, except (1) if such person did not act in good faith in the reasonable belief that his actions were in or not opposed to the best interests of the Trust or (2) for willful misfeasance, bad faith, gross negligence or reckless disregard of duties in the conduct of his office or the discharge of his functions on the part of such Trustee or officer (the conduct described in (1) and (2) being referred to herein as “Disabling Conduct”). The Declaration of Trust provides that each Portfolio shall indemnify each Trustee and officer and permit advances for the payment of expenses relating to the matter for which indemnification is sought to the fullest extent permitted by applicable law.

SHAREHOLDER LIABILITY. Massachusetts law provides that shareholders of a Portfolio could, under certain circumstances, be held personally liable for the obligations of a Portfolio. However, the Declaration of Trust disclaims shareholder liability for acts or obligations of the Trust and requires that notice of such disclaimer be given in each agreement, obligation or instrument entered into or executed by the Trust or a Trustee. The Declaration of Trust provides for indemnification from a Portfolio’s property for all losses and expenses of any shareholder held personally liable for the

obligations of the Trust. Thus, the risk of a shareholder’s incurring financial loss on account of shareholder liability is limited to circumstances in which the relevant Portfolio would be unable to meet its obligations, a possibility that Credit Suisse believes is remote and immaterial. Upon payment of any liability incurred by the Trust, the shareholder paying the liability will be entitled to reimbursement from the general assets of the relevant Portfolio. The Trustees intend to conduct the operations of the Trust in such a way so as to avoid, as far as possible, ultimate liability of the shareholders for liabilities of the Trust.

The foregoing is only a summary of certain characteristics of the operations of each of the Portfolios. The foregoing is not a complete description of the documents cited. Shareholders should refer to the provisions of the constituent documents and state laws governing each Portfolio for a more thorough description.

CONCLUSION

The Agreement was approved by the Board of Trustees of the Portfolios on February 14, 2007. The Board has determined that the Acquisition is in the best interests of its shareholders and that the interests of existing shareholders of its Portfolio will not be diluted as a result of the Acquisition. If the shareholders of the Acquired Portfolio do not approve the Agreement or if the Acquisition is not completed, the Acquired Portfolio will continue to engage in business as a registered investment company and its Board of Trustees will consider other possible courses of action available to it, including resubmitting the Acquisition proposal to shareholders.

REQUIRED VOTE

Approval of the Agreement requires the affirmative vote of a majority of the outstanding shares of the Acquired Portfolio, in the aggregate without regard to class, present in person or represented by proxy, if a quorum is present.

THE BOARD OF TRUSTEES OF THE ACQUIRED
PORTFOLIO, INCLUDING THE TRUSTEES WHO ARE NOT
“INTERESTED PERSONS” (AS THAT TERM IS DEFINED IN THE
1940 ACT) RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL.

VOTING INFORMATION

This Prospectus/Proxy Statement is furnished in connection with a solicitation of proxies by the Board of Trustees of the Acquired Portfolio to be used at the Special Meeting of Shareholders of the Acquired Portfolio to be held at [ ] [a.m./p.m.] on [ ], 2007, at the offices of the Acquired Portfolio, Eleven Madison Avenue, 24th Floor, New York, New York 10010 and at any adjournment(s) thereof.

This Prospectus/Proxy Statement, along with a Notice of the Special Meeting and proxy card(s), is first being mailed to shareholders of the Acquired Portfolio on or about [ ], 2007. Only shareholders of record as of the close of business on the Record Date will be entitled to notice of, and to vote at, the Special Meeting or any adjournment(s) thereof. As of the Record Date, the Acquired Portfolio had [ ] shares outstanding. The holders of a majority of the outstanding shares of beneficial interest of the Acquired Portfolio entitled to vote at the close of business on the Record Date present in person or represented by proxy will constitute a quorum for the Special Meeting.

The Trust, on behalf of its Portfolios, offers its shares only to Participating Insurance Companies for allocation to certain of their separate accounts established for the purpose of funding variable annuity contracts, variable life insurance contracts, and tax qualified pension and retirement plans. Under current law, the Participating Insurance Companies are required to solicit voting instructions from variable annuity contract owners who beneficially own shares in the Acquired Portfolio as of the Record Date and must vote all shares held in the separate account in proportion to the voting instructions received for the Special Meeting, or any adjournment thereof. The Participating Insurance Companies will vote shares of the Acquired Portfolio for which no instructions have been received in the same proportion as they vote shares for which they have received instructions. Abstentions will have the effect of a negative vote on the Proposal for the Acquired Portfolio. Unmarked voting instructions will be voted in favor of the Proposal. If you hold shares through a variable annuity contract or a variable life insurance policy, and if you do not give specific voting instructions for your shares, they may not be voted at all or, as described above, they may be voted in a manner that you may not intend. Therefore, you are strongly encouraged to give your Participating Insurance Company specific instructions as to how you want your shares to be voted.

A proxy may be revoked at any time on or before the Special Meeting by the subsequent execution and submission of a revised proxy, by written notice to J. Kevin Gao, Secretary of the Trust, Eleven Madison Avenue, New York, New York 10010 or by voting in person at the Special Meeting. Contract Owners should consult their Participating Insurance Company regarding their ability to revoke voting instructions after such instructions have been provided to the Participating Insurance Company.

Credit Suisse has retained [SOLICITOR] & Co., Inc. to solicit proxies. Proxy solicitations will be made primarily by mail, but proxy solicitations also may be made by telephone, facsimile or personal interviews conducted by officers and employees of Credit Suisse and its affiliates. The expenses of the Acquisition, which are currently estimated to be $[ ], including the costs of the proxy solicitations and the preparation of enclosures to the Prospectus/Proxy Statement, reimbursement of expenses of forwarding solicitation material to beneficial owners of shares of beneficial interest of the Acquired Portfolio and expenses incurred in connection with the preparation of this Prospectus/Proxy Statement, will be borne by Credit Suisse or its affiliates (excluding extraordinary expenses not normally associated with transactions of this type).

In the event that a quorum necessary to vote on the Proposal at the Special Meeting is not present or sufficient votes to approve the Proposal are not received prior to [ ] [a.m./p.m.] on [ ], 2007, the persons named as proxies may propose one or more adjournments of the Special Meeting to permit further solicitation of proxies to receive the vote necessary for its passage or to obtain a quorum. In determining whether to adjourn the Special Meeting, the following factors may be considered: the percentage of votes actually cast, the percentage of negative votes actually cast, the nature of any further solicitation and the information to be provided to shareholders with respect to the reasons for the solicitation. Any such adjournment will require an affirmative vote by the holders of a majority of the shares of beneficial interest of the Acquired Portfolio present in person or by proxy and entitled to vote at the Special Meeting. The persons named as proxies will vote upon a decision to adjourn the Special Meeting after consideration of the best interests of all shareholders of the Acquired Portfolio.

OTHER BUSINESS

The Board of Trustees of the Acquired Portfolio knows of no other business to be brought before the Special Meeting. However, if any other matters come before the Special Meeting, proxies that do not contain specific restrictions to the contrary will be voted on such matters in accordance with the judgment of the persons named in the enclosed Proxy Card.

The approval of shareholders of the Acquiring Portfolio is not required in order to affect the Acquisition and, accordingly, the votes of the shareholders of the Acquiring Portfolio are not being solicited by this Prospectus/Proxy Statement.

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (the “Agreement”) is made as of this day of , 2007, by Credit Suisse Trust (the “Trust”) on behalf of its series, the Credit Suisse Small Cap Core II Portfolio (the “Acquired Fund”) and the Credit Suisse Small Cap Core I Portfolio (the “Acquiring Fund”) (the Acquired Fund and Acquiring Fund, collectively, the “Funds”), and, solely for purposes of Sections 4.2, 5.7 and 8.2 hereof, Credit Suisse Asset Management, LLC, a limited liability company organized under the laws of the State of Delaware (“Credit Suisse”).

This Agreement is intended to be and is adopted as a plan of reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). The reorganization of the Acquired Fund (collectively, the “Reorganization”) will consist of the transfer of all of the assets of the Acquired Fund in exchange solely for shares of beneficial interest (collectively, the “Shares”) of the Acquiring Fund and the assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund, and the distribution, on or after the Closing Date hereinafter referred to, of Shares of the Acquiring Fund (“Acquiring Fund Shares”) to the shareholders of the Acquired Fund in liquidation of the Acquired Fund as provided herein, all upon the terms and conditions hereinafter set forth in this Agreement.

As the Funds are each series of the Trust, all parties to this Agreement acknowledge and accept that each Fund does not have a Board of Trustees or officers separate from the other series of the Trust. Accordingly, all representations, warranties, covenants and/or other obligations of any kind made by each Fund in this Agreement are expressly understood by all parties to this Agreement as being made by the Trustees or officers of the Trust, as applicable, in their respective capacities as Trustees or officers (and not in their individual capacities) for, and on behalf of, each Fund.

WHEREAS, the Board of Trustees of the Trust, on behalf of the Acquired Fund, has determined that the exchange of all of the assets of the Acquired Fund for Acquiring Fund Shares and the assumption of the liabilities of the Acquired Fund by the Acquiring Fund is in the best interests of the Acquired Fund and that the interests of the existing shareholders of the Acquired Fund would not be diluted as a result of this transaction; and

WHEREAS, the Board of Trustees of the Trust, on behalf of the Acquiring Fund, has determined that the exchange of all of the assets of the Acquired Fund for Acquiring Fund Shares is in the best interests of the Acquiring Fund’s shareholders and that the interests of the existing shareholders of the Acquiring Fund would not be diluted as a result of this transaction.

NOW, THEREFORE, in consideration of the premises and of the covenants and agreements hereinafter set forth, the parties hereto covenant and agree as follows:

1. Transfer of assets of the Acquired Fund in exchange for Acquiring Fund Shares and assumption of the Acquired Fund’s liabilities and liquidation of the Acquired Fund.

1.1. Subject to the terms and conditions herein set forth and on the basis of the representations and warranties contained herein, the Acquired Fund agrees to transfer its assets as set forth in paragraph 1.2 to the Acquiring Fund, and the Acquiring Fund agrees in exchange

therefor: (i) to deliver to the Acquired Fund the number of Acquiring Fund Shares, including fractional Acquiring Fund Shares, determined by dividing the value of the Acquired Fund’s net assets, computed in the manner and as of the time and date set forth in paragraph 2.1, by the net asset value of one Acquiring Fund Share; and (ii) to assume the liabilities of the Acquired Fund, as set forth in paragraph 1.3. Such transactions shall take place at the closing provided for in paragraph 3.1 (the “Closing”).

1.2. (a) The assets of the Acquired Fund to be acquired by the Acquiring Fund shall consist of all property including, without limitation, all cash, securities and dividend or interest receivables that are owned by or owed to the Acquired Fund and any deferred or prepaid expenses shown as an asset on the books of the Acquired Fund on the Closing date provided in paragraph 3.1 (the “Closing Date”).

(b) The Acquired Fund has provided the Acquiring Fund with a list of all of the Acquired Fund’s assets as of the date of execution of this Agreement. The Acquired Fund reserves the right to sell any of these securities but will not, without the prior approval of the Acquiring Fund, acquire any additional securities other than securities of the type in which the Acquiring Fund is permitted to invest. The Acquired Fund will, within a reasonable time prior to the Closing Date, furnish the Acquiring Fund with a list of the securities, if any, on the Acquired Fund’s list referred to in the first sentence of this paragraph which do not conform to the Acquiring Fund’s investment objective, policies and restrictions. In the event that the Acquired Fund holds any investments which the Acquiring Fund may not hold, the Acquired Fund will dispose of such securities prior to the Closing Date. In addition, if it is determined that the portfolios of the Acquired Fund and the Acquiring Fund, when aggregated, would contain investments exceeding certain percentage limitations imposed upon the Acquiring Fund with respect to such investments, the Acquired Fund, if requested by the Acquiring Fund, will dispose of and/or reinvest a sufficient amount of such investments as may be necessary to avoid violating such limitations as of the Closing Date.

1.3. The Acquired Fund will endeavor to discharge all of the known liabilities and obligations of the Acquired Fund prior to the Closing Date, other than those liabilities and obligations which would otherwise be discharged at a later date in the ordinary course of business. The Acquiring Fund shall assume all liabilities, expenses, costs, charges and reserves, including those liabilities reflected on unaudited statements of assets and liabilities of the Acquired Fund and the Acquiring Fund prepared by State Street Bank and Trust Company (“State Street”), the accounting agent of each Fund, as of the Valuation Date (as defined in paragraph 2.1), in accordance with generally accepted accounting principles consistently applied from the prior audited period. The Acquiring Fund shall also assume any liabilities, expenses, costs or charges incurred by or on behalf of the Acquired Fund specifically arising from or relating to the operations and/or transactions of the Acquired Fund prior to and including the Closing Date but which are not reflected on the above-mentioned statement of assets and liabilities, including any liabilities, expenses, costs or charges arising under paragraph 5.5 hereof.

1.4. As soon on or after the Closing Date as is conveniently practicable (the “Liquidation Date”), the Acquired Fund will liquidate and distribute pro rata to the Acquired Fund’s shareholders of record determined as of the close of business on the Closing Date (the “Fund Shareholders”) the Acquiring Fund Shares it receives pursuant to paragraph 1.1. Such

liquidation and distribution will be accomplished by the transfer of the Acquiring Fund Shares then credited to the account of the Acquired Fund on the books of the Acquiring Fund to open accounts on the share records of the Acquiring Fund in the name of the Acquired Fund’s shareholders representing the respective pro rata number of the Acquiring Fund Shares due such shareholders. All issued and outstanding shares of the Acquired Fund will simultaneously be canceled on the books of the Acquired Fund, although share certificates representing interests in the Acquired Fund will represent a number of Acquiring Fund Shares after the Closing Date as determined in accordance with Section 2.2. The Acquiring Fund shall not issue certificates representing the Acquiring Fund Shares in connection with such exchange.

1.5. Ownership of Acquiring Fund Shares will be shown on the books of the Acquiring Fund’s transfer agent. Shares of the Acquiring Fund will be issued in the manner described in the Acquiring Fund’s current prospectuses and statement of additional information.

1.6. Any transfer taxes payable upon issuance of the Acquiring Fund Shares in a name other than the registered holder of the Acquired Fund Shares on the books of the Acquired Fund as of that time shall, as a condition of such issuance and transfer, be paid by the person to whom such Acquiring Fund Shares are to be issued and transferred.

1.7. Any reporting responsibility of the Acquired Fund is and shall remain the responsibility of the Acquired Fund up to and including the Closing Date and such later date on which the Acquired Fund is terminated.

2. Valuation

2.1. The value of the Acquired Fund’s assets to be acquired hereunder shall be the value of such assets computed as of the close of regular trading on The New York Stock Exchange, Inc. (the “NYSE”) on the Closing Date (such time and date being hereinafter called the “Valuation Date”), using the valuation procedures set forth in the Acquired Fund’s then current prospectuses or statement of additional information.

2.2. The number of Shares of the Acquiring Fund to be issued (including fractional shares, if any) in exchange for shares of beneficial interest of the Acquired Fund shall be determined by dividing the value of the net assets of the Acquired Fund attributable to its shares of beneficial interest determined using the same valuation procedures referred to in paragraph 2.1 by the net asset value per Share of the Acquiring Fund computed as of the close of regular trading on the NYSE on the Closing Date, using the valuation procedures set forth in the Acquiring Fund’s then current prospectuses or statement of additional information.

2.3. All computations of value with respect to the Acquiring Fund and the Acquired Fund shall be made by State Street in accordance with its regular practice as pricing agent for the Acquiring Fund.

3. Closing and Closing Date

3.1. The Closing Date for the Reorganization shall be , 2007, or such other date as the parties to such Reorganization may agree to in writing. All acts taking place at the Closing shall be deemed to take place simultaneously as of the close of trading on the NYSE

on the Closing Date unless otherwise provided. The Closing shall be held as of [a.m./p.m.], at the offices of Willkie Farr & Gallagher LLP or at such other time and/or place as the parties may agree.

3.2. State Street Bank and Trust Company, the custodian for the Acquiring Fund (the “Custodian”), shall deliver as soon as practicable after the Closing a certificate of an authorized officer stating that: (a) the Acquired Fund’s portfolio securities, cash and any other assets have been delivered in proper form to the Acquiring Fund on the Closing Date and (b) all necessary taxes, including all applicable federal and state stock transfer stamps, if any, have been paid, or provision for payment has been made, in conjunction with the delivery of portfolio securities.

3.3. In the event that on the Valuation Date (a) the NYSE or another primary trading market for portfolio securities of the Acquiring Fund or the Acquired Fund shall be closed to trading or trading thereon shall be restricted or (b) trading or the reporting of trading on the NYSE or elsewhere shall be disrupted so that accurate appraisal of the value of the net assets of the Acquiring Fund or the Acquired Fund is impracticable, the Closing Date shall be postponed until the first business day after the day when trading shall have been fully resumed and reporting shall have been restored.

3.4.

(the “Commission”) as an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”), is in full force and effect;

(d) No litigation or administrative proceeding or investigation of or before any court or governmental body is presently pending or to its knowledge threatened against the Funds or any of their properties or assets which, if adversely determined, would materially and adversely affect their financial condition or the conduct of their business.

(e) The Statements of Assets and Liabilities of the Acquired Fund as of December 31, 2006, including the Schedule of Investments and the related Statement of Operations for the year then ended, the Statement of Changes in Net Assets for each of the two years in the period then ended and the Financial Highlights for each of the five years in the period then ended, have been audited by [AUDITOR] (or one of its legacy firms), independent registered public accountants and are in accordance with generally accepted accounting principles consistently applied, and such statements (copies of which have been furnished to the Acquiring Fund) fairly reflect the financial condition of the Acquired Fund as of such dates, and there are no known contingent liabilities of the Acquired Fund as of , 2007 not disclosed therein.

For purposes of this subsection (f), a decline in net asset value per share of a Fund due to declines in market values of securities in a Fund’s portfolio, the discharge of Fund liabilities, or the redemption of Fund shares by Fund shareholders shall not constitute a material adverse change;

(g) At the date hereof and at the Closing Date, all federal and other tax returns and reports, including extensions, of each Fund required by law to have been filed by such dates shall have been filed and are or will be correct in all material respects, and all federal and other taxes shall have been paid so far as due, or provision shall have been made for the payment thereof and, to the best of each Fund’s knowledge, no such return is currently under audit and no assessment has been asserted with respect to such returns;

(k) The information to be furnished by the Acquiring Fund and Acquired Fund for use in applications for orders, registration statements or proxy materials or for use in any other document filed or to be filed with any federal, state or local regulatory authority (including the NASD, Inc.), which may be necessary in connection with the transactions contemplated hereby, shall be accurate and complete in all material respects and shall comply in all material respects with federal securities and other laws and regulations applicable thereto;

5. Covenants of the Acquired Fund and the Acquiring Fund

5.1. The Acquiring Fund and the Acquired Fund will operate their respective businesses in the ordinary course between the date hereof and the Closing Date. It is understood that such ordinary course of business will include the declaration and payment of customary dividends and distributions.

5.2. The Trust, on behalf of the Acquired Fund, will call a meeting of the shareholders of the Acquired Fund to consider and act upon this Agreement and to take all other actions necessary to obtain approval of the transactions contemplated herein.

5.3. The Acquired Fund covenants that (i) the Acquiring Fund Shares to be issued hereunder are not being acquired for the purpose of making any distribution thereof other than in accordance with the terms of this Agreement; (ii) to the best of the knowledge of the Acquired Fund, there is no plan or intention by Acquired Fund’s Shareholder to sell, exchange or otherwise dispose of a number of Acquired Fund Shares (or Acquiring Fund Shares received in the Reorganization), in connection with the Reorganization, that would reduce the Acquired Fund Shareholders’ ownership of Acquired Fund Shares (or equivalent Acquiring Fund Shares) to a number of shares that is less than 50 percent of the number of Acquired Fund Shares as of the record date of the Reorganization; and (iii) the Acquired Fund will not take any position on any federal, state or local income or franchise tax return, or take any other tax reporting position, that is inconsistent with the treatment of the Reorganization as a “reorganization” within the meaning of Section 368(a) of the Code.

5.4. Subject to the provisions of this Agreement, the Acquiring Fund and the Acquired Fund will each take, or cause to be taken, all action, and do or cause to be done, all things reasonably necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement.

5.5. The Acquiring Fund agrees to indemnify and advance expenses to each person who at the time of the execution of this Agreement serves as a Trustee or Officer (“Indemnified Person”) of the Trust, against money damages actually and reasonably incurred by such Indemnified Person in connection with any claim that is asserted against such Indemnified Person arising out of such person’s service as a Trustee or officer of the Trust, as such service involves the Acquired Fund, with respect to matters specifically relating to the Reorganization, provided that such indemnification and advancement of expenses shall be permitted to the fullest

extent that is available under applicable law. This paragraph 5.5 shall not protect any such Indemnified Person against any liability to the Acquired Fund, the Acquiring Fund or their shareholders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or from reckless disregard of the duties involved in the conduct of his office. An Indemnified Person seeking indemnification shall be entitled to advances from the Acquiring Fund for payment of the reasonable expenses incurred by him in connection with the matter as to which he is seeking indemnification in the manner and to the fullest extent permissible under applicable law. Such Indemnified Person shall provide to the Acquiring Fund a written affirmation of his good faith belief that the standard of conduct necessary for indemnification by the Acquiring Fund under this paragraph has been met and a written undertaking to repay any advance if it should ultimately be determined that the standard of conduct has not been met. In addition, at least one of the following additional conditions shall be met: (a) the Indemnified Person shall provide security in form and amount acceptable to the Acquiring Fund for its undertaking; (b) the Acquiring Fund is insured against losses arising by reason of the advance; or (c) either a majority of a quorum of disinterested non-party directors of the Acquiring Fund, or independent legal counsel experienced in mutual fund matters, selected by the Indemnified Person, in a written opinion, shall have determined, based on a review of facts readily available to the Acquiring Fund at the time the advance is proposed to be made, that there is reason to believe that the Indemnified Person will ultimately be found to be entitled to indemnification.

5.6. The intention of the parties is that the transaction will qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither the Acquiring Fund, the Acquired Fund nor the Trust shall take any action, or cause any action to be taken (including, without limitation, the filing of any tax return) that is inconsistent with such treatment or results in the failure of the transaction to qualify as a reorganization within the meaning of Section 368(a) of the Code. At or prior to the Closing Date, the Acquiring Fund, the Acquired Fund and the Trust will take such action, or cause such action to be taken, as is reasonably necessary to enable Willkie Farr & Gallagher LLP to render the tax opinion contemplated here in Section 7.6.

5.7. Credit Suisse agrees that the Acquiring Fund will succeed to all rights that the Acquired Fund has, or would have but for the Reorganization, against Credit Suisse or its affiliates by reason of any act or failure to act by Credit Suisse or any of its affiliates prior to the Closing Date.

These policies provide insurance for any “Wrongful Act” of an officer, director or trustee. Wrongful Act is defined as breach of duty, neglect, error, misstatement, misleading statement, omission or other act done o r wrongfully attempted by an officer, Director or Trustee in connection with the operation of Registrant.

Under Section 8.1 of the Declaration of Trust (the “Declaration”), the Trustees and officers of Registrant, in incurring any debts, liabilities or obligations, or in taking or omitting any other actions for or in connection with Registrant, are or shall be deemed to be acting as Trustees or officers of Registrant and not in their own capacities. No Trustee, officer, employee or a gent of the Trust shall be subject to any personal liability whatsoever in tort, contract, or otherwise, to any other person or persons in connection with the assets or affairs of Registrant save only that arising from his own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office or the discharge of his functions. Registrant shall be solely liable for any and all debts, claims, demands, judgments, decrees, liabilities or obligations of any and every kind, against or with respect to Registrant in tort, contract or otherwise in connection with the assets or the affairs of Registrant and all persons dealing with Registrant shall be deemed to have agreed that resort shall be had solely to the Trust Property (as defined in the Declaration) of Registrant for the payment or performance thereof.

Section 8.2 of the Declaration further li mits the liability of the Trustees by providing that a Trustee shall not be liable for errors of judgment or mistakes of fact or law. Furthermore, (i) the Trustees shall not be responsible or liable in any event for any neglect or wrongdoing of any officer, agent, employee, consultant, Investment Adviser, Administrator, Distributor, Custodian or Transfer Agent (as such terms are defined in the Declaration) of Registrant, nor shall any Trustee be responsible for the act or omission of any other Trustee; (ii) the Trustees may take advice of counsel or other experts with respect to the meaning and operation of the Declaration and their duties as Trustees, and shall be under no liability for any act or omission in accordance with such advice or for failing to follow such advice; and (iii) in discharging their duties, the Trustees, when acting in good faith, shall be entitled to rely upon the books of account of Registrant and upon written reports made to the Trustees by any officer appointed by them, any i ndependent registered public accountant, and (with respect to the subject matter of the contract involved) any officer, partner or responsible employee of a contracting party appointed by the Trustees pursuant to Section 3 of the Declaration. The Trustees are not required to give any bond or surety or any other security for the performance of their duties.

Under Section 8.4 of the Declaration any past or present Trustee or officer of Registrant (including persons who serve at Registrant’s request as directors, officers or trustees of another organization in which Registrant has any interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”)) is indemnified to the fullest extent permitted by law against liability and all expenses reasonably incurred by him in connection with any action, suit or proceeding to which he may be a party or otherwise involved by reason of his being or having been a Covered Person. This provision does not authorize indemnification when it is determined, in the manner specified in the Declaration that such Covered Person has not acted in good faith in the reasonable belief that his actions were in or not opposed to the best interests of Registrant. Moreover, this provision doe s not authorize indemnification when it is determined, in the manner specified in the Declaration, that such Covered Person would otherwise be liable to Registrant or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his duties. Expenses may be paid by Registrant in advance of the final disposition of any action, suit or proceeding upon receipt of an undertaking by such Covered Person to repay such expenses to Registrant in the event that it is ultimately determined that indemnification of such expenses is not authorized under the Declaration and either (i) the Covered Person provides security for such undertaking, (ii) Registrant is insured against losses from such advances or (iii) the disinterested Trustees or independent legal counsel determines, in the manner specified in the Declaration, that there is reason to believe the Covered Person will be found to be entitled to indemnification.

Insofar as indemnification for liability arising under the Securities Act of 1933, as amended (the “Act”), may be permitted to Trustees, officers and controlling persons of Registrant pursuant to the foregoing provisions, or otherwise, Registrant has been advised that in the opinion of the Securities and Exchange Commission (“SEC”) such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a Trustee, officer or controlling person of Registrant in the successful defense of any action, suit or proceeding) is asserted by such Trustee, officer or controlling person in connection with the securities being registered, Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
