SIEMENS WANTS TO AMEND TELECOM PLUS <TELE> PACT Telecom Plus International Inc said <Siemens AG>'s Siemens Information Systems wants to amend its agreement to purchase Telecom's 65 pct interest in Tel Plus Communications to delay payment of 25 mln dlrs for 11 months. Telecom's shareholders are scheduled to vote on the 165 mln dlr transaction Monday. Telecom said it advised Siemens it intends to close the transaction on March 16, as scheduled, if it is approved by shareholders. A spokesman said this means Telecom will decide before the 16th whether or not to accept the proposed change. Explaining its request for the amendment, Siemens informed Telecom it had recently become aware of information causing concern with respect to certain accounting and other matters. Siemens said it will therefore need to continue its review beyond March 16 to determine whether certain representations and warranties are true. Telecom said it advised Siemens it knows of no information which would make its representations and warranties untrue. Siemens already owns the remaining 35 pct of Tel Plus. The 65 pct represenmts Telecom's principal operating asset. A Telecom spokesman said the agreement calls for payment of all but 29 mln dlrs of the price at closing. Of this, 21 mln dlrs was to be paid 11 months later and two mln dlrs per year on the anniversary date of the transaction. He said Siemens is now proposing that 25 mln dlrs be added to the 21 mln dlrs to be paid in 11 months. Telecom said the proposed amendment would also permit Siemens to defer repayment of up to an additional 50 pct of certain intercompany debt until completion of the review. Telecom said it estimates this to ba about 15 mln dlrs.
