Key legal question
Whether the contractual clause should be qualified as suretyship or cumulative debt assumption.
Extracted holding
The clause was to be qualified as cumulative debt assumption, not suretyship.
Extracted reasoning
The appellant had a recognizable, direct economic interest in the share transaction: the buyer and appellant pursued the same goal of removing the managing director and creating the basis for the appellant to acquire additional shares. Because the creditor could recognize this interest, the protective formal requirements for suretyship did not apply.
