UPDATE 1-Micro Focus says Borland gets rival bid

* Says its offer in best interests of both companies

* Borland gets non-binding indication of interest

* Micro Focus shares fall 8 pct, Borland soars 19 pct (Adds details)

June 1 (Reuters) - British software company Micro Focus International Plc (MCRO.L), which agreed last month to buy Borland Software Corp (BORL.O), said on Monday that Borland had received a preliminary non-binding indication of interest from an unnamed financial buyer.

Micro Focus said it believed its fully funded offer was based on strong strategic rationale and was in the best interests of both companies.

The FTSE 250-listed company said the boards of both Micro Focus and Borland had unanimously recommended its offer.

Micro Focus said on May 6 it had made a recommended cash offer to buy Austin, Texas-based Borland for about $75 million in cash.

Separately, Micro Focus said it completed the acquisition of the application testing and automated software quality business of Compuware Corp (CPWR.O), which it had agreed to buy earlier for about $58 million.

The group said the two deals would give Micro Focus a leading market position in the software testing business, estimated to be worth about $2 billion a year, and would complement Micro Focus's core software modernisation business.

Micro Focus shares were down 8 percent at 362.5 pence on the London Stock Exchange at 1413 GMT, while Borland shares jumped 19 percent to $1.17 on Nasdaq. (Reporting by Austin Lobo in Bangalore; Editing by Mike Miller)
