帮我撰写英文的合同条款内容：但是代理方需要为上述项目向公司开立履约保函和或质保保函等且保函金额与前述条款中代理的职责范围同等开具保函后才能支付给代理方。

However, the agent shall be required to provide the company with a performance bond and/or a warranty bond for the aforementioned project. The bond amount shall be equivalent to the scope of the agent's responsibilities stated in the aforementioned clauses. Payment to the agent shall only be made upon the issuance of the bond.
