Introductory Statement

This is the final amendment to the Issuer Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission on October 17, 2008 (the “Statement Filing Date”) by Morgan Stanley Institutional Fund of Hedge Funds LP (the “Fund”) relating to an offer to purchase limited partner interests in the Fund (“Interests”) in an amount up to 15% of the net assets of the Fund from limited partners of the Fund (“Limited Partners”) at their net asset value (i.e., the value of the Fund’s assets minus its liabilities, multiplied by the respective proportionate dollar-weighted percentages of the Fund represented by the Interests tendered by Limited Partners) on the terms, and subject to the conditions, set out in the Offer to Purchase and the related Letter of Transmittal. Copies of the Offer to Purchase and the Letter of Transmittal were previously filed as Exhibits B and C to the Statement on the Statement Filing Date.

This final amendment to the Statement is being filed to report the results of the Offer. The following information is furnished pursuant to Rule 13e-4(c)(4) of the Securities Exchange Act of 1934:

1. Limited Partners which desired to tender Interests were required to submit their tenders by 12:00 midnight, Eastern time, on November 17, 2008 (the “Notice Date”). Limited Partners were allowed to withdraw any tenders of their Interests until the Offer expired at 12:00 midnight, Eastern time, on December 30, 2008 (the “Expiration Date”).

2. Certain Limited Partners validly tendered all or some of their respective Interests (as designated by such Limited Partners) as $400,732,398 in the aggregate before the Notice Date and did not withdraw such tenders before the Expiration Date. Those tenders were accepted for repurchase by the Fund in accordance with the terms of the Offer.

3. The net asset value of the Interests tendered pursuant to the Offer was calculated as of December 31, 2008 (the “Valuation Date”).

4. The payment of the purchase price of the Interests tendered was made in the form of promissory notes respectively given on December 1, 2008 to the Limited Partners whose tenders were accepted for purchase by the Fund in accordance with the terms of the Offer. Pursuant to the promissory notes, the Fund paid on or about January 28, 2009 to the tendering Limited Partners a total of $388,760,452, representing more than 90% of the unaudited net asset value of the total amount of the Interests tendered by Limited Partners. The promissory note issued to a Limited Partner also entitles such Limited Partner to receive a contingent post-audit payment equal to the amount (if any) by which the net asset value of the Interest tendered by such Limited Partner and purchased by the Fund as of the Valuation Date (as such net asset value may be adjusted based on the next annual audit of the Fund’s financial statements) exceeds the initial payment to such Limited Partner. The post-audit payment will be paid promptly after the completion of the Fund’s annual audit. Proceeds of the initial payment and post-audit payment will be wire-transferred directly to the account designated by the Limited Partner.
