         The undersigned hereby appoints Dennis B. Gillings, Ph.D. and Santo J.
Costa and each of them as attorney and proxy of the undersigned, each with the
full power of substitution and with authority in each of them to act in the

         Proposal One         Approval of the issuance of approximately
                        28,421,000 shares of Quintiles common stock to the
                        shareholders of ENVOY Corporation, a Tennessee
                        corporation, in exchange for their shares of ENVOY
                        common stock and ENVOY Series B convertible preferred
                        stock pursuant the Merger Agreement.

                  [  ] FOR              [  ] AGAINST          [  ] ABSTAIN

         Proposal Two         Approval of an amendment to Quintiles' Amended and
                        Restated Articles of Incorporation to increase the
                        number of authorized shares of Quintiles common stock
                        from 200,000,000 to 500,000,000.

                  [  ] FOR              [  ] AGAINST          [  ] ABSTAIN

         
         This proxy will be voted as directed by the undersigned shareholder.
Unless contrary direction is given, this proxy will be voted FOR each proposal.
The undersigned shareholder may revoke this proxy at any time before it is voted
by delivering to the Secretary of Quintiles either a written revocation of the
proxy or a duly executed proxy bearing a later date, or by appearing at the
Special Meeting and voting in person. The undersigned shareholder hereby
acknowledges receipt of notice of the Special Meeting and Joint Proxy
Statement/Prospectus dated February __, 1999 and hereby revokes any proxy or
proxies heretofore given.

          By signing a proxy, the undersigned shareholder authorizes the proxy 
holder to vote in his discretion regarding any procedural motions which may 
come before the Special Meeting. For example, this authority could be used to 
adjourn the Special Meeting if Quintiles believes it is desirable to do so. 
Adjournment or other procedural matters could be used to obtain more time 
before a shareholder vote in order to solicit additional proxies or to provide 
additional information to shareholders. Quintiles has no plans to adjourn the 
meeting at this time, but intends to do so if it believes that doing so would 
promote shareholder interests.
