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在此前提下公司才能支付佣金给代理方。

However, the agent shall be required to provide the company with a performance bond and/or warranty bond for the aforementioned project, with a bond amount equal to the scope of the agency responsibilities as stated in the aforementioned terms. Only upon fulfillment of this condition, the company shall be liable to pay the commission to the agent.
