The University Board of Trustees re-elected all seven of its incumbent officers Saturday morning, keeping board President J. Lloyd Huck and Vice President Mimi Coppersmith for a traditional third term.

Coppersmith, however, received eight abstentions in an election in which all incumbents were unanimously re-elected.

Board members would not comment on their reasons for voting or abstaining.

Last semester, questions arose when the University and Coppersmith entered a rental agreement for downtown office space. Some criticized the move as a conflict of interest, but University officials said the action was a sound business decision.

Board members re-elected the uncontested nominees by secret ballot to serve one-year terms ending in January 1991.

Coppersmith, president of Barash Advertising Inc. and Morgan Signs Inc., has been a board member for 14 years. A 1953 graduate with a bachelor's degree in journalism, she has served as chairwoman of the Special Advisory Committee on Affirmative Action, the Committee on Educational Policy and the Distinguished Alumni Award Screening Committee.

Huck, chairman of both the Nova Pharmaceutical Corporation in Baltimore and the Mutual Benefit Life Insurance Company, has been a member of the board since 1977 and served as vice president from 1985 to 1987.

He graduated from the University in 1943 with a bachelor's degree in chemistry and has served as a past president of the Penn State Alumni Council, an Alumni Fellow of the colleges of Medicine and Science, and a member of the Campaign Executive Committee.

Re-elected board officers include:

-- Grace T. Younginger as the board's associate secretary.

-- Carolyn A. Dolbin, administrative assistant to the president, and Joseph F. Krawiec, director of systems and administrative services, as the board's assistant secretaries.

-- Steve A. Garban, senior vice president for finance and operations and treasurer, as treasurer.

-- Raymond D. Nargi, director of financial management, as associate treasurer.

-- David E. Branigan as the board's assistant treasurer.

Bryce Jordan remained the board's secretary ex officio.
