Electro-Optical Sciences, Inc. Added to Russell 2000(R) and Russell 3000(R) Indexes

IRVINGTON, NY--(Marketwire - June 29, 2009) - Electro-Optical Sciences, Inc. ("EOS") (NASDAQ: MELA), a medical technology company focused on the design and development of MelaFind®, a non-invasive, point-of-care instrument to assist in the early detection of melanoma, today announced that the company's shares have been added to the Russell 2000® and Russell 3000® indexes, effective immediately.

Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the Russell 2000 Index as well as the appropriate growth and value style indexes. Member companies are drawn from the 4,000 largest companies meeting the indexes' criteria as of the end of each May and are added or deleted annually as the indexes are reconstituted each June.

"We are pleased to be included in both Russell indexes and believe that this will bring a more diverse group of shareholders to the stock and may generate additional attention to the company as MelaFind advances through the regulatory pathway at the Food and Drug Administration," said Joseph V. Gulfo, M.D., Chief Executive Officer of EOS.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. According to Russell, an industry-leading $4 trillion in assets currently are benchmarked to them.
