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这有在这个前提下才能支付佣金给代理方。

However, the agent is required to obtain a performance bond and/or warranty bond from the company for the aforementioned project, with the bond amount being equivalent to the scope of responsibilities undertaken by the agent as stated in the aforementioned terms. Only under this condition, the commission will be paid to the agent.
