Steinhoff is in talks with creditors over an agreement to hold off debt claims for three years while the troubled South African retailer restructures €9 billion of debt, it said on Wednesday.
"The launch of the LUA (lock-up agreement) marks the culmination of several weeks of discussions with the ad hoc committees of third party creditors," Steinhoff said in a statement.
"(It) represents an important step in the restructuring process."
Steinhoff shares jumped following the announcement and were up more than 20% at 2.26 rand per share by 1517 GMT.
Creditors have until 16 July to sign the lock-up agreement, the owner of Mattress Firm in the United States and Poundland in Britain said.
The company hopes the deal will provide period of stability while the complex restructuring process is completed.
Cut off from credit lines, Steinhoff has been surviving on cash injections from asset sales.
In June it said it had agreed the main terms of a restructuring deal, under which all its debt would be restated at par and be given a common maturity date of three years from the completion of the restructuring agreement.
The lock-up agreement has been signed by the company, Steinhoff Finance Holding, Steinhoff Europe AG (SEAG), SUSHI and Steinhoff International Holdings Proprietary Limited.
