MAMSI Announces Partnership with TLC Laser Eye Centers to Offer Savings for Health Plan Members

Rockville, MD: Mid Atlantic Medical Services, Inc. (MAMSI) (NYSE:MME) announced today it has entered into an exclusive strategic alliance with TLC Laser Eye Centers (NASDAQ:TLCV). Effective immediately, all MAMSI Health Plan members can receive significant savings for laser vision correction services at TLC Laser Eye Centers (TLC). MAMSI Health Plans are the first health plans to enter into a strategic alliance with TLC in the Mid Atlantic region.

TLC provides laser vision correction services throughout North America. TLC owns and manages refractive centers and is affiliated with over 13,000 Optometrists and Ophthalmologists who provide laser vision correction of common refractive disorders such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. TLC made national headlines recently when it announced a multi-year endorsement agreement with golf superstar Tiger Woods, who won an astounding five straight tournaments after having his vision corrected at TLC.

"This is a forward looking, new strategic alliance for us," said Mark D. Groban, M.D., Chairman of MAMSI's Board. "Many of our members will be able to take advantage of the terrific savings they will receive from TLC and enjoy the benefits of improved vision."

While the health insurance products offered by MAMSI Health Plans exclude laser vision correction services such as LASIK and PRK, the alliance with TLC will make this service more affordable and available to MAMSI Health Plan members. MAMSI Health Plan members may use any TLC center in North America and receive a discount for services.

It is easy to take advantage of this new value added service. MAMSI Health Plan members simply call the TLC Information Response Center (IRC) at 877-PLAN-TLC to schedule a complimentary personal evaluation and initial consultation. Members can find a conveniently located TLC center by calling the IRC or visiting TLC's web site, www.tlcvision.com. There are no claim forms to fill out and TLC offers various payment arrangements.

MAMSI is one of the mid-Atlantic region's largest managed care companies. Its health plans include MD-Individual Practice Association, Inc. (M.D. IPA), MAMSI Life and Health Insurance Company (MLH), Optimum Choice, Inc.® (OCI), Optimum Choice of the Carolinas, Inc. (OCCI) and Alliance PPO, LLC. (Alliance). MAMSI Health Plans cover about 1.8 million lives. The Company's Internet address is www.mamsi.com.
