RESEARCH TRIANGLE PARK, N.C. – March 17, 2006 – Quintiles Transnational Corp. ("Quintiles") and Pharma Services Intermediate Holding Corp. ("Holding;" each of Holding and Quintiles, is referred to as a "Company") today announced that, in connection with the previously announced tender offer and consent solicitation for any and all of Quintiles' outstanding $450.0 million aggregate principal amount 10% senior subordinated notes due 2013 (CUSIP Nos. 748767 AE0 and 748767 AD2)(the "Subordinated Notes") and any and all of Holding's outstanding $219.0 million aggregate principal amount at maturity 11.5% senior discount notes due 2014 (CUSIP No. 71711W AB6)(the "Discount Notes"), the requisite consents have been received to approve certain amendments to the indentures under which the respective Notes were issued. The amendments to the indentures will eliminate or make less restrictive most of the restrictive covenants contained in the indentures and amend certain related provisions.

Approximately $446.0 million principal amount, or 99.1%, of the outstanding principal amount of the Subordinated Notes and $219.0 million principal amount at maturity, or 100.0%, of the outstanding principal amount at maturity of the Discount Notes, and the consents related thereto, have been validly tendered by the consent payment deadline of 5:00 p.m. New York City time, Thursday, March 16, 2006 (the "Consent Payment Deadline"). Each Company expects to execute a supplemental indenture incorporating the amendments with Wells Fargo Bank, N.A., as trustee under each indenture, as described in the Companies' Offer to Purchase and Consent Solicitation Statement, dated March 3, 2006, as soon as practical. However, the amendments will not become operative unless and until the Companies purchase the validly tendered Notes pursuant to the tender offer.

All withdrawal rights of tendering holders of Notes terminated at 5:00, p.m., New York City time on Thursday, March 16, 2006. Accordingly, tendering holders may no longer withdraw their Notes. Holders who have not yet tendered their Notes may tender at or prior to 12:00 midnight on Thursday, March 30, 2006. Quintiles and Holding have elected to pay the total consideration, including the consent payment, for all validly tendered Notes, including those tendered subsequent to the Consent Payment Deadline. The total consideration and the consent payment for the Notes are each described in the Offer to Purchase. Each Company's obligation to consummate the tender offer is subject to the prior satisfaction or waiver of the conditions precedent described in the Offer to Purchase.

The Companies have engaged Citigroup Corporate and Investment Banking to act as dealer manager in connection with the tender offer. Questions regarding the tender offer may be directed to Citigroup at (800) 558-3745 (toll-free) and (212) 723-6106 (collect).

This press release does not constitute an offer to buy, the solicitation of an offer to sell or the solicitation of consents with respect to the Notes. In accordance with any state securities laws applicable to the tender offer in the United States which require the tender offer to be made to the public by a licensed broker or dealer, the tender offer shall be deemed to be made to the holders of Notes residing in those states by Citigroup on behalf of the Companies. The tender offer and solicitation of consents is made solely pursuant to the Offer to Purchase and Consent Solicitation Statement dated March 3, 2006.
