Ladies and Gentlemen:

We have served as counsel to NDCHealth Corporation (the “Company”) in connection with the filing by the Company of a registration statement on Form S-8 with the Securities and Exchange Commission (the “Commission”), relating to the registration pursuant to the provisions of the Securities Act of 1933, as amended (the “Act”), of 185,189 shares (the “Shares”) of the Company’s Common Stock, par value $.125 per share (the “Common Stock”), reserved for issuance under the TechRx Incorporated 1999 Stock Option Plan (the “Plan”). The Company assumed the Plan and outstanding stock options thereunder pursuant to that certain Agreement and Plan of Merger by and among the Company, NDC Acquisition Corp., and TechRx Incorporated, dated the 28^th day of May, 2002. All references in the Plan to TechRx Incorporated shall be deemed to be references to the Company.

As counsel for the Company, we have examined certain books and records of the Company and have made such other investigations as we have deemed necessary for purposes of this opinion. In such examinations we have assumed the genuineness of all signatures on all original documents, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all copies submitted to us, the authenticity of the originals of documents submitted to us as copies, and the due execution and delivery of all documents where due execution and delivery are prerequisite to the effectiveness thereof.

As to questions of fact material to this opinion, we have relied solely upon certificates and statements of officers of the Company and certain public officials. We have assumed and relied upon the accuracy and completeness of such certificates and statements, the factual matters set forth therein, and the genuineness of all signatures thereon, and nothing has come to our attention leading us to question the accuracy of the matters set forth therein. We have made no independent investigation with regard thereto and, accordingly, we do not express any view or belief as to matters that might have been discovered by independent verification.

Based upon and subject to the foregoing, we are of the opinion that the Shares reserved for issuance in accordance with the Plan have been duly authorized and will, when and to the extent certificates evidencing the Shares have been duly executed, countersigned, registered, issued and delivered upon the exercise of options granted and executed in accordance with the Plan and the respective agreements thereunder, be validly issued, fully paid and non-assessable.

We are members of the Bar of the State of Georgia. In expressing the opinions set forth above, we are not passing on the laws of any jurisdiction other than the General Corporation Law of the State of Delaware and the Federal laws of the United States of America.

This opinion is limited to the matters expressly opined on herein, and no opinion may be implied or inferred beyond those expressly stated. This opinion is rendered as of the date hereof, and we make no undertaking and expressly disclaim any duty to supplement or update such opinion, if, after the date hereof, facts or circumstances come to our attention or changes in the law occur which could affect such opinion. This opinion is being furnished to you solely for your benefit in connection with the transactions contemplated by the Plan and, except as expressly set forth below, is not to be used, circulated, quoted or otherwise referred to for any other purpose without our prior express written consent and may not be relied upon by any other person without our express written consent.

We hereby consent to the filing of this opinion or copies thereof as an exhibit to the registration statement referred to above.

Very truly yours,
