The bid represents a 28% premium over Pacific Internet's closing price of $6.46 on Friday. MediaRing, which already owns slightly less than 5% of Pacific Internet, said that a deal is contingent upon it securing a minimum ownership of 50% plus one share.

Shares of Pacific Internet were trading up 99 cents to $7.45.

Mentor Graphics ( MENT) fell 7% after the software company said it would sell $175 million in convertible subordinated debentures due 2026 in a private placement. The company plans to use the proceeds from the offering to retire convertible subordinated notes due 2007. Mentor expects to grant purchasers of the $175 million in debentures a 30-day option to buy an additional $25 million in debentures to cover over-allotments. If the over-allotment option is exercised, Mentor plans to use those proceeds to repurchase a portion of its outstanding floating-rate convertible subordinated debentures due 2023. Shares were recently trading down 79 cents to $11.37.
