A.H. ROBINS <QRAH> TO CONSIDER RORER OFFER A.H. Robins Co said its board has concluded that the merger proposal submitted by Rorer Group Inc <ROR> merits further consideration. At the request of the board, Rorer has agreed to extend until 1800 EDT July 2 its deadline for response from A.H. Robins. After Rorer announced its second bid for the company last Thursday, analysts forecast that the Robins family, which holds control of the company, would vigourously oppose any merger. But, the analysts added, that Robins desire to emerge independent from two years of bankruptcy proceedings may be thwarted by some Robins' shareholders who perceive a merger as a more expedient way of dealing with the company's Dalkon Shield related liabilities. After a failed first attempt earlier this year, Rorer's latest merger plan calls for a share swap worth about 720 mln dlrs. Rorer would also set up two trusts to cover the estimated 1.75 billion dlrs in liabilities to deal with about 320,000 claims by women who suffered maladies from the use of the Dalkon Shield interuterine device.
