We have audited the accompanying statement of assets, liabilities and members' capital of Advantage Advisers Xanthus Fund, L.L.C. (the "Company"), including the schedules of portfolio investments, securities sold, not yet purchased, and swap contracts as of December 31, 2006, and the related statement of operations for the year then ended, and the statements of changes in members' capital for each of the two years in the period then ended. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2006, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Advantage Advisers Xanthus Fund, L.L.C. at December 31, 2006, the results of its operations for the year then ended, and the changes in its members' capital for each of the two years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP New York, New York February 22, 2007 A Member Practice of Ernst & Young Global -1- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C.

NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 - -------------------------------------------------------------------------------- 1. ORGANIZATION Advantage Advisers Xanthus Fund, L.L.C. (the "Company") was organized as a limited liability company under the laws of Delaware in January 1999. The Company is registered under the Investment Company Act of 1940, as amended (the "Act"), as a closed-end, non-diversified management investment company. The Company's term is perpetual unless the Company is otherwise terminated under the terms of the Limited Liability Company Agreement dated as of June 5, 2003. The Company's investment objective is to achieve maximum capital appreciation. It pursues this objective by actively investing in a portfolio consisting primarily of equity securities of technology companies and of companies which derive a major portion of their revenue directly or indirectly from technological events and advances. The Company's portfolio of securities in the technology area is expected to include long and short positions primarily in equity securities of U.S. and non-U.S. companies. Equity securities include common and preferred stock and other securities having equity characteristics, including convertible debt securities, stock options, warrants and rights. Responsibility for the overall management and supervision of the operations of the Company is vested in the individuals who serve as the Board of Managers of the Company (the "Board of Managers"). There are six members of the Board of Managers, one of whom is considered an "interested person" under the Act. On March 1, 2006, the Company named James E. Buck as lead Independent Manager of the Board of Managers. The Company's investment adviser is Advantage Advisers Management, L.L.C., a Delaware limited liability company (the "Adviser"). The Adviser is a subsidiary of Oppenheimer Asset Management Inc. ("OAM") and an affiliate of Oppenheimer & Co. Inc. ("Oppenheimer"). The Adviser is responsible for managing the Company's investment activities pursuant to an investment advisory agreement dated June 5, 2003. OAM is the managing member of the Adviser, and Alkeon Capital Management L.L.C. ("Alkeon") is a non-managing member of the Adviser. Investment professionals employed by Alkeon, including Mr. Takis Sparaggis, who serves as the Company's portfolio manager, manage the Company's portfolio on behalf of the Adviser under the supervision of OAM. Oppenheimer has a minority profit participation interest in Alkeon. The acceptance of initial and additional contributions from Members is subject to approval by the Board of Managers. At a meeting held on November 1, 2004, the Board of Managers approved the acceptance of initial contributions by the Company from new members on or after January 1, 2005. The Company may from time to time offer to repurchase interests pursuant to written tenders by Members. Such repurchases will be made at such times and on such terms as may be determined by the Board of Managers, in their complete and exclusive discretion. The Adviser expects that generally it will recommend to the Board of Managers that the Company offer to repurchase interests from Members twice each year, effective at the end of the second fiscal quarter and again at the end of the year. Generally, except as provided under applicable law, a Member shall not be liable for the Company's debts, obligations and liabilities in any amount in excess of the capital account balance of such Member, plus such Member's share of undistributed profits and assets. -18- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 2. SIGNIFICANT ACCOUNTING POLICIES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires the Adviser to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Adviser believes that the estimates utilized in preparing the Company's financial statements are reasonable and prudent; however, actual results could differ from these estimates. A. REVENUE RECOGNITION Securities transactions, including related revenue and expenses, are recorded on a trade-date basis, and dividends are recorded on the ex-dividend date, net of applicable withholding taxes. Interest income and expense are recorded on the accrual basis. Premiums and discounts on fixed income securities are amortized using the effective interest rate method. B. PORTFOLIO VALUATION The Company's securities are valued in accordance with policies adopted by the Board of Managers, which are summarized below. (i) Domestic exchange traded securities (other than options and those securities traded on NASDAQ) shall be valued: (1) at their last composite sale prices as reported on the exchanges where those securities are traded; or (2) If no sales of those securities are reported on a particular day, the securities are valued based upon their composite bid prices for securities held long, or their composite asked prices for securities sold, not yet purchased, as reported by those exchanges. (ii) Securities traded on NASDAQ shall be valued: (1) at the NASDAQ Official Closing Price ("NOCP") (which is the last trade price at or before 4:00 PM (Eastern Time) adjusted up to NASDAQ's best offer price if the last traded price is below such bid and down to NASDAQ's best offer price if the last trade is above such offer price); or (2) if no NOCP is available, at the last sale price on the NASDAQ prior to the calculation of the net asset value of the Company; or -19- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) B. PORTFOLIO VALUATION (CONTINUED) (3) if no sale is shown on NASDAQ, at the bid price; or (4) if no sale is shown and no bid price is available, the price will be deemed "stale" and the value will be determined in accordance with the fair valuation procedures set forth herein. Securities traded on a foreign securities exchange will be valued at their last sale prices on the exchange where such securities are primarily traded, or in the absence of a reported sale on a particular day, at their bid prices (in the case of securities held long) or asked prices (in the case of securities sold, not yet purchased) as reported by such exchange. Listed options will be valued at their bid prices (or asked prices in the case of listed written options) as reported by the exchange with the highest volume on the last day a trade was reported. Other securities for which market quotations are readily available will be valued at their bid prices (or asked prices in the case of securities sold, not yet purchased) as obtained from one or more dealers making markets for those securities. If market quotations are not readily available, securities and other assets will be valued at fair value as determined in good faith by, or under the supervision of, the Board of Managers. Debt securities will be valued in accordance with the procedures described above, which with respect to such securities may include the use of valuations furnished by a pricing service which employs a matrix to determine valuation for normal institutional size trading units or consultation with brokers and dealers in such securities. The Board of Managers will periodically monitor the reasonableness of valuations provided by any such pricing service. Debt securities with remaining maturities of 60 days or less will, absent unusual circumstances, be valued at amortized cost, so long as such valuation is determined by the Board of Managers to represent fair value. All assets and liabilities initially expressed in foreign currencies will be converted into U.S. dollars using foreign exchange rates provided by a pricing service compiled as of 4:00 p.m. London time. Trading in foreign securities generally is completed, and the values of such securities are determined, prior to the close of securities markets in the U.S. Foreign exchange rates are also determined prior to such close. On occasion, the values of such securities and exchange rates may be affected by events occurring between the time such values or exchange rates are determined and the time that the net asset value of the Company is determined. When such events materially affect the values of securities held by the Company or its liabilities, such securities and liabilities will be valued at fair value as determined in good faith by, or under the supervision of, the Board of Managers. -20- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) B. PORTFOLIO VALUATION (CONTINUED) Fair value shall take into account the relevant factors and surrounding circumstances, which may include: (i) the nature and pricing history (if any) of the security or other investment; (ii) whether any dealer quotations are available; (iii) possible valuation methodologies that could be used to determine fair value; (iv) the recommendation of the Adviser with respect to the valuation; (v) whether the same or similar securities or other investments are held by other accounts or other funds managed by the Adviser and the valuation method used by the Adviser with respect thereto; (vi) the extent to which the fair value to be determined will result from the use of data or formulae produced by third parties independent of the Adviser; and (vii) the liquidity or illiquidity of the market for the security or other investment. The fair value of the Company's assets and liabilities which qualify as financial instruments under Statement of Financial Accounting Standards No. 107, "Disclosures about Fair Value of Financial Instruments," approximates the carrying amounts presented in the Statement ofAssets, Liabilities and Members' Capital. C. CASH EQUIVALENTS The Company treats all highly liquid financial instruments that mature within three months at the time of purchase as cash equivalents. D. INCOME TAXES No provision for the payment of Federal, state or local income taxes on the profits of the Company is made as the Members are individually liable for the income taxes on their share of the Company's income. The Company has reclassified ($2,272,925) and $50,724,619 from accumulated net investment loss and accumulated net realized gain on investments, respectively, to net capital contributions during the year ended December 31, 2006. This reclassification was a result of permanent book to tax differences to reflect, as an adjustment to net capital contributions, the amounts of taxable loss and net realized gain on investments that have been allocated to the Company's Members and had no effect on net assets. 3. ADMINISTRATION FEE, RELATED PARTY TRANSACTIONS AND OTHER Oppenheimer provides certain administrative services to the Company including, among other things, providing office space and other support services. In exchange for such services, the Company pays Oppenheimer a monthly administration fee of 0.08333% (1% on an annualized basis) of the Company's net assets determined as of the beginning of the month. -21- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 3. ADMINISTRATION FEE, RELATED PARTY TRANSACTIONS AND OTHER (CONTINUED) During the year ended December 31, 2006, Oppenheimer earned $251,654 as brokerage commissions from portfolio transactions executed on behalf of the Company. Mainsail Group, L.L.C., a broker-dealer affiliate of Alkeon, earned $1,522,053 as brokerage commissions from portfolio transactions executed on behalf of the Company. Net profits or net losses of the Company for each fiscal period are allocated among and credited to or debited against the capital accounts of all Members (but not the Special Advisory Member) as of the last day of each fiscal period in accordance with Members' respective investment percentages for the fiscal period. The Adviser, in its capacity as the Special Advisory Member of the Company, is entitled to receive an incentive allocation (the "Incentive Allocation"), charged to the capital account of each Member as of the last day of each allocation period, of 20% of the amount by which net profits, if any, exceed the positive balance in the Member's "loss recovery account." The Incentive Allocation is credited to the Special Advisory Account of the Adviser. By the last business day of the month following the date on which an Incentive Allocation is made, the Adviser may withdraw up to 100% of the Incentive Allocation that was credited to the Special Advisory Account with respect to the allocation period. During the year ended December 31, 2006, an Incentive Allocation of $15,713,324 was credited to the Special Advisory Member's capital account and was included in withdrawals payable at December 31, 2006, in the Statement of Assets, Liabilities and Members' Capital. Each member of the Board of Managers (each a "Manager") who is not an "interested person" of the Company, as defined by the Act, receives an annual retainer of $5,000 plus a fee for each meeting attended. The lead independent manager receives an additional fee of $2,500. Managers who are "interested persons" do not receive any annual or other fee from the Company. Managers who are not "interested persons" are reimbursed by the Company for all reasonable out-of-pocket expenses incurred by them in performing their duties. PFPC Trust Company (the "Custodian") serves as custodian of the Company's assets. PFPC Inc. ("PFPC") serves as investor services and accounting agent to the Company and in that capacity provides certain accounting, recordkeeping and investor related services. The Company pays PFPC an accounting and investor services fee based primarily on the average net assets of the Company as of the last day of each month, payable monthly, subject to a minimum annual fee. Oppenheimer acts as the non-exclusive placement agent for the Company, without special compensation from the Company, and bears costs associated with its activities as placement agent. However, the placement agent is entitled to charge a sales commission of up to 3% (up to 3.1% of the amount invested) in connection with a purchase of interests, at its discretion. For the year ended December 31, 2006, such sales commissions earned by Oppenheimer amounted to $156,650. -22- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 4. INDEMNIFICATIONS The Company has entered into several contracts that contain routine indemnification clauses. The Company's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. However, based on experience, the Company expects the risk of loss to be remote. 5. SECURITIES TRANSACTIONS Aggregate purchases and sales of investment securities, excluding short-term securities, for the year ended December 31, 2006, amounted to $2,677,113,040 and $2,637,436,507, respectively. Aggregate purchases and sales of securities sold, not yet purchased, excluding short-term securities, for the year ended December 31, 2006, amounted to $1,510,786,614 and $1,609,068,843, respectively. At December 31, 2006, the aggregate cost for Federal income tax purposes of portfolio investments and securities sold, not yet purchased was $483,709,250, and $214,852,584, respectively. For Federal income tax purposes, at December 31, 2006, accumulated net unrealized appreciation on portfolio investments and securities sold, not yet purchased was $28,897,783, consisting of $41,381,068 gross unrealized appreciation and $12,483,285 gross unrealized depreciation. Due from broker primarily represents proceeds from securities sold, not yet purchased, net of excess cash, held at the prime broker as of December 31, 2006. 6. SHORT-TERM BORROWINGS The Company has the ability to trade on margin and, in that connection, borrow funds from brokers and banks for investment purposes. Trading in equity securities on margin involves an initial cash requirement representing at least 50% of the underlying security's value with respect to transactions in U.S. markets and varying percentages with respect to transactions in foreign markets. The Act requires the Company to satisfy an asset coverage requirement of 300% of its indebtedness, including amounts borrowed, measured at the time the Company incurs the indebtedness. The Company pays interest on outstanding margin borrowings at an annualized rate of LIBOR plus 0.875%. The Company pledges securities as collateral for the margin borrowings, which are maintained in a segregated account held by the Custodian. As of and for the year ended December 31, 2006, the Company had no outstanding margin borrowings. -23- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 7. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK OR CONCENTRATIONS OF CREDIT RISK In the normal course of business, the Company may trade various financial instruments and enter into various investment activities with off-balance sheet risk. These financial instruments include options, swaps and securities sold, not yet purchased. Generally, these financial instruments represent future commitments to purchase or sell other financial instruments at specific terms at specified future dates. Each of these financial instruments contains varying degrees of off-balance sheet risk whereby changes in the market value of the securities underlying the financial instruments may be in excess of the amounts recognized in the statement of assets, liabilities and members' capital. The Company maintains cash in bank deposit accounts which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on such bank deposits. Securities sold, not yet purchased represent obligations of the Company to deliver specified securities and thereby creates a liability to purchase such securities in the market at prevailing prices. Accordingly, these transactions result in off-balance sheet risk as the Company's ultimate obligation to satisfy the sale of securities sold, not yet purchased may exceed the amount indicated in the statement of assets, liabilities and members' capital. Primarily all investments in securities sold, not yet purchased and due from broker are positions with, and amounts due from, the prime broker, Morgan Stanley. Accordingly, the Fund has a concentration of individual counterparty credit risk with the prime broker. The Fund pledges securities in an account at PFPC Trust Company, for the benefit of the prime broker, to meet the margin requirement as determined by the prime broker. A swap is a contract under which two parties agree to make periodic payments to each other based on specified interest rates, an index or the value of some other instrument, applied to a stated, or "notional" amount. Swaps generally can be classified as interest rate swaps, currency swaps, commodity swaps or equity swaps which can also include contracts for difference, depending on the type of index or instrument used to calculate the payments. Such swaps would increase or decrease the Company's investment exposure to the particular interest rate, currency, commodity or equity involved. Securities associated with swaps are marked-to-market based on the Company's valuation procedures that are outlined in Section 2b of these notes. The change in value of swaps, including the periodic amounts of interest to be paid or received on swaps, is reported as unrealized gains or losses in the Statement of Operations. Net unrealized gains are reported as an asset and net unrealized losses are reported as a liability on the Statement of Assets, Liabilities and Members' Capital. A realized gain or loss is recorded upon payment or receipt of a periodic payment or termination of swap agreements. Most swap agreements entered into by the Company require the calculation of the obligations of the parties to the agreements on a "net basis." Consequently, current obligations (or rights) under a swap agreement generally will be equal to only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the "net amount"). -24- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C. NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 2006 (CONTINUED) - -------------------------------------------------------------------------------- 7. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK OR CONCENTRATIONS OF CREDIT RISK (CONTINUED) The Company is subject to the market risk associated with changes in the value of the underlying investment or instrument, as well as exposure to credit risk associated with counterparty non-performance on swap contracts. The risk of loss with respect to swaps is limited to the net amount of payments that the Company is contractually obligated to make. If the other party to a swap defaults, the Fund's risk of loss consists of the net amount of payments that the Company contractually is entitled to receive, which may be different than the amounts recorded on the Statement of Assets, Liabilities and Members' Capital. The unrealized appreciation/depreciation, rather than the notional amount, represents the approximate future cash to be received or paid, respectively. The risk associated with purchasing an option is that the Company pays a premium whether or not the option is exercised. Additionally, the Company bears the risk of loss of premium and change in market value should the counterparty not perform under the contract. Put and call options purchased are accounted for in the same manner as investment securities. When the Company writes an option, the premium received by the Company is recorded as a liability and is subsequently adjusted to the current market value of the option written. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Company has realized a gain or loss. In writing an option, the Company bears the market risk of an unfavorable change in the price of the security or index underlying the written option. Exercise of an option written by the Company could result in the Company selling or buying a security at a price different from the current market value.

RECENT ACCOUNTING PRONOUNCEMENTS On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Company's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. Recent SEC guidance allows deferring the implementation of FIN 48. As a result, the Company will incorporate FIN 48 in its semi annual report on June 30, 2007. In September 2006, the Financial Accounting Standards Board (FASB) issued STATEMENT ON FINANCIAL ACCOUNTING STANDARDS NO. 157, "FAIR VALUE MEASUREMENTS" (FAS 157). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of fair value measurements. FAS 157 is effective for fianancial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. As of December 31, 2006, the Company does not believe the adoption of FAS 157 will impact the amounts reported in the financial statements, however, additional disclosures will be required about the inputs used to develop the measurements of fair value and the effect of certain of the measurements reported in the statement of operations for a fiscal year. 10. SUBSEQUENT EVENTS Subsequent to December 31, 2006 and through February 22, 2007, the Company received initial and additional capital contributions from Members of $10,412,783. -28- ADVANTAGE ADVISERS XANTHUS FUND, L.L.C.

Alkeon has instructed ISS to vote all proxies in accordance with this policy, unless instructed by Alkeon to vote otherwise.

For all other proposals, Alkeon will vote in accordance with the proxy voting guidelines adopted by ISS. Clients may obtain a copy of the Proxy Procedures and information about how Alkeon voted a client's proxies by contacting Greg Jakubowsky via e-mail at gjakubowsky@alkeoncapital.com or by telephone at (212) 389-8710.

PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES. (A)(1) IDENTIFICATION OF PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBERS AND DESCRIPTION OF ROLE OF PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBERS Panayotis Sparaggis has served as the Portfolio Manager of the Fund since its inception. Mr. Sparaggis is the Chief Investment Officer and a controlling person of Alkeon Capital Management, LLC ("Alkeon"), which he founded in December 2001. From May 1995 until the founding of Alkeon , Mr. Sparaggis was employed by CIBC World Markets Corp or its predecessors. (A)(2) OTHER ACCOUNTS MANAGED BY PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBER AND POTENTIAL CONFLICTS OF INTEREST OTHER ACCOUNTS MANAGED BY PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBER The table below includes details about the type, number, and assets under management for the various types of accounts, and total assets in the accounts with respect to which the advisory fee is based on the performance of the accounts that Mr. Sparaggis managed as of December 31, 2006: -------------------- ------------- ------------ ---------------- -------------- ------------------------- No. of Accounts Total where Total Assets in Name of Portfolio No. of Advisory Fee Accounts where Advisory Manager or Type of Accounts is Based on Fee is Based on TEAM MEMBER ACCOUNTS MANAGED Total ASSETS PERFORMANCE PERFORMANCE -------------------- ------------- ------------ ---------------- -------------- ------------------------- Panayotis Sparaggis Registered 1 $21,318,844 1 $21,318,844 Investment Companies: -------------------- ------------- ----------------------------- -------------- ------------------------- Panayotis Sparaggis Other 6 $298,974,321 6 $298,974,321 Pooled Investment Vehicles: -------------------- ------------- ----------------------------- -------------- ------------------------- Panayotis Sparaggis Other 0 $0 0 $0 Accounts: -------------------- ------------- ----------------------------- -------------- ------------------------- POTENTIAL CONFLICTS OF INTERESTS Actual or apparent conflicts of interest may arise when a Portfolio Manager also has day-to-day responsibilities with respect to one or more accounts. These potential conflicts include: o Allocation of Limited Time and Attention. Because the Portfolio Manager manages other accounts, the Portfolio Manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as if the Portfolio Manager were to devote substantially more attention to the management of fewer accounts. o Allocation of Investment Opportunities. If the Portfolio Manager identifies an investment opportunity that may be suitable for multiple accounts, the Fund may not be able to take full advantage of that opportunity because the opportunity may need to be allocated among all or many of these accounts. -38- o Pursuit of Differing Strategies. At times, the Portfolio Manager may determine that an investment opportunity may be appropriate for only some of the accounts for which he exercises investment responsibility, or may decide that certain of these accounts should take differing positions with respect to a particular security. In these cases, the Portfolio Manager may execute differing or opposite transactions for one or more accounts which may affect the market price of the security or the execution of the transactions, or both, to the detriment of one or more of his accounts. o Performance Fees. The Portfolio Manager manages other accounts that are subject to a performance allocation or performance fee which in some cases may be greater than the fee payable by the Fund. This could create a conflict because the Portfolio Manager may benefit if a more attractive investment is allocated to an account that bears a greater performance allocation or fee. (A)(3) COMPENSATION STRUCTURE OF PORTFOLIO MANAGER(S) OR MANAGEMENT TEAM MEMBERS Mr. Sparaggis' compensation consists of periodic advances and the income from the profits of Alkeon Capital Management, LLC derived by him as its sole principal. The level of Alkeon Capital Management's profitability in turn is dependent on the advisory fees and performance fees and allocations received from the Fund and other advisory clients.
