Pursuant to the terms of the Merger Agreement and subject to the conditions thereof, each issued and outstanding share of Radiologix’s common stock, other than shares owned by stockholders who are entitled to and who properly exercise dissenters’ rights under applicable law, will be cancelled and converted automatically into the right to receive the per share Merger Consideration. Holders of options exercisable for Radiologix common stock, whose exercise price is less than the value of the per share Merger Consideration, will receive for each share subject to such options an amount in cash out of the aggregate Merger Consideration equal to the difference between the value of the per share Merger Consideration and the exercise price of their options.

The Merger Agreement contains certain termination rights for both Primedex and Radiologix and provides that upon termination of the Merger Agreement under specified circumstances, either Radiologix or Primedex may be required to reimburse the other for its out-of-pocket expenses in connection with the Merger in an aggregate amount of up to $1 million. The Merger Agreement further provides that upon termination of the Merger Agreement under specified circumstances Radiologix may be required to pay Primedex a termination fee of $3 million.

As a material inducement to the willingness of Primedex to enter into the Merger Agreement, simultaneously with the execution of the Merger Agreement, a certain stockholder of Radiologix is entering into a voting agreement with Primedex to vote its shares of Radiologix in favor of the Merger and against any proposal made in opposition to or in competition with the Merger.

The Merger is expected to be completed in the second half of 2006, subject to regulatory approvals, the approvals of Primedex’s and Radiologix’s stockholders, as well as other customary closing conditions. Radiologix has filed a copy of the Merger Agreement as Exhibit 2.1 to this current report on Form 8-K. You are encouraged to read the Merger Agreement for a more complete understanding of the transaction. The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement.
