                      MAGELLAN HEALTH SERVICES ENTERS INTO
                  STRATEGIC PARTNERSHIP WITH TEXAS PACIFIC GROUP

               TPG TO INVEST IN MAGELLAN AND JOIN BOARD OF DIRECTORS
- ------------------------------------------------------------------------------

COLUMBIA, Md. -- July 19, 1999 -- Magellan Health Services, Inc. (NYSE:MGL)
today announced that it has signed an investment agreement with Texas Pacific
Group (TPG) whereby TPG will invest approximately $75 million in cumulative
convertible preferred stock of Magellan Health Services. Magellan and TPG
have established the framework for an additional investment by TPG of up to
$70 million, subject to mutual agreement between Magellan and TPG regarding
the terms of the investment. Additionally, TPG has the right to increase its
ownership in Magellan by up to 10% through share purchases in the open market.

     Henry Harbin, president and CEO of Magellan Health Services said, "We
are pleased to bring on TPG as our partner. Their financial and healthcare
expertise will serve us well, as we continue to improve the company's
financial position and strategic focus."

     Harbin continued, "Management and TPG share a common vision for
Magellan's future, which centers around continuous improvement of our leading
expertise and position in the behavioral managed care segment and focused
growth in our specialty managed care segment. With TPG's help, we will
continue to push forward on our plan to further improve our balance sheet
while we continue to integrate acquisitions that are strategic and beneficial
to our long-term growth plan. While the investment will be dilutive to
earnings per share, TPG's investment, along with continued disposition of
non-core assets, will strengthen our financial flexibility and further
position us for growth."

     Jonathan Coslet, senior partner of Texas Pacific Group, added, "Magellan
has developed a unique platform in the behavioral managed care market.
Consolidation of its recent acquisitions is going well, and the company is
really starting to leverage the combined resources and expertise. We also are
very excited about the approach Magellan is taking in the specialty managed
care market. The company understands how to add value to its payor customers,
while maintaining high levels of care."

     The $75 million investment by TPG is made up of approximately $59
million of Series A cumulative convertible preferred stock and approximately
$16 million of Series B cumulative convertible preferred stock. The Series A
cumulative convertible preferred stock will have 6.3 million "as converted"
voting rights and a cumulative dividend of 6.5%, which will be payable at
Magellan's option in cash, additions to the stated value of the Series A or,
subject to certain conditions, common stock. The conversion price on the
Series A cumulative convertible preferred stock of $9.375 represents an
approximate 21% premium over the last 90 days trading average of the
Company's common stock. Completion of the Series B investment and the terms
of such investment are subject to a Magellan shareholder vote. Upon
shareholder approval, the Series B will have 1.7 million "as converted"
voting rights giving TPG a total of approximately 20% of the voting rights of
Magellan.

     Under the agreement, TPG will also get three board seats on Magellan's
board of directors. Completion of the investment by TPG is subject to lender
approval, regulatory approval and other customary closing conditions.

care organization. The company is comprised by three main business units:
