(NASDAQ: IHSC) today announced a major capital infusion, which includes the purchase by The Carlyle Group of $25 million in new Preferred Stock at $8.38 per share. Simultaneously, InSight has executed a definitive agreement with NationsBank, N.A. for $125 million in senior secured credit financing. In addition, InSight has created a new class of Preferred Stock, part of which has been issued to GE in exchange for the early buyout of its supplemental service fee arrangement with InSight, and the balance of which is expected to be issued to GE shortly in exchange for its existing Series A Preferred Stock. The Company's Board will be expanded to nine members. As a result of their investment in InSight, Carlyle and GE have received the right to appoint two directors, and one director, respectively. - MORE - INSIGHT HEALTH SERVICES PAGE 2 Frank E. Egger, InSight's Chairman of the Board stated, "This capital infusion is strong evidence of The Carlyle Group's and GE's support for this management team and the long-term strategic direction InSight is pursuing. It places the Company in a significantly stronger financial position from which to execute its business plan. It also enhances InSight's ability to maximize shareholder value." E. Larry Atkins, InSight's President and Chief Executive Officer added, "This capital infusion is an enormous step forward for InSight - one that substantially boosts our resources, lowers our cost of capital and fuels our future growth. We are in the midst of several growth initiatives, including acquisitions, expansion of open MRI units and continued development of our radiology co-sourcing product. All these programs will be supported from a stronger capital base as a result of this investment. We are delighted to be associated with organizations of Carlyle's, NationsBank's and GE's caliber. The conversion price of the new Preferred Stock is at a supplemental premium to the recent trading price of our Common Stock, which we believe is a real vote of confidence from these organizations."

The working capital and acquisition facilities will result in $75 million of new capacity to fuel growth and acquisitions. These senior credit facilities will result in a two hundred basis point reduction in current interest rate costs over the refinanced debt. Funding is subject to the satisfaction of certain customary conditions and is expected to occur within two weeks. THE CONVERTIBLE SECURITIES As part of the transaction, GE has agreed to convert all of its existing non-voting Series A Preferred Stock into the new Series C Preferred Stock upon expiration or earlier termination of the 30-day waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. GE has also received 835,821 shares of Series C Preferred Stock in exchange for the early cancellation of the supplemental service fee agreement, thereby eliminating InSight's annual expense representing a fourteen percent pretax income payment to GE. This termination will result in a non-recurring expense of approximately $6.7 million in the second quarter of fiscal 1998. When converted, GE's holdings would represent 34 percent of the current fully-diluted outstanding shares, and has an initial conversion price of $8.38 per share of Common Stock. GE has also acquired warrants to purchase 250,000 shares of InSight Common Stock at an initial exercise price of $10.00 per share. The Series B Preferred Stock purchased by Carlyle will be convertible initially into an aggregate of 2,985,075 shares of InSight Common Stock, or 31 percent of the fully-diluted outstanding shares, at an initial conversion price of $8.38 per share of Common Stock. Carlyle has also acquired warrants to purchase 250,000 shares of InSight Common Stock at an initial exercise price of $10.00 per share. - MORE - INSIGHT HEALTH SERVICES PAGE 4 The new Preferred will vote with the Common Stock on all matters except the election of directors, but will be limited to a maximum aggregate vote equal to 37 percent of the votes eligible to be cast on such matters.
