BRIERLEY OFFER FOR PROGRESSIVE STILL VALID <Brierley Investments Ltd>, (BIL), said its offer of 4.20 N.Z. Dlrs per share for supermarket group <Progressive Enterprises Ltd> still stands, although <Rainbow Corp Ltd> said today it has 52 pct of Progressive. BIL said in a statement it will review events on a daily basis. Rainbow announced earlier that it had increased its stake in Progressive to 52 pct from 44 pct through the purchase of 9.4 mln shares at between 3.80 and 4.80 N.Z. Dlrs per share. BIL chief executive Paul Collins said: "All Rainbow has done is to outlay a substantial amount of cash to purchase shares from parties who presumably were supportive of the merger." Rainbow has proposed a merger with Progressive to form a new company, <Astral Pacific Corp Ltd>. Under the merger, shareholders in both Progressive and Rainbow will be issued shares in the new company on a one-for-one basis. "Quite simply, Rainbow should now bid for the balance of Progressive Enterprises at 4.80 N.Z. Dlrs per share," Collins said.
