A企业为了控制合同风险,明确规定其法定代表人张某对外签定合同的最高限额为 200万元。2005年4月1日,张某在一次商品交易会上,为了抓住稍纵即逝的商机,代表A企业与B企业签订了一份250万元的买卖合同,B企业并不知道张某违反了A企业的内部规定。按照买卖合同的约定,由A企业在2005年6月5日前向B企业提供货物,B企业收到货物后的10天内支付货款250万元。 2005年6月1日,A企业按照合同约定完成全部货物的生产,6月2日A企业有确切证据得知B企业经营状况严重恶化,可能无力支付250万元的货款。6月5日,B企业要求 A企业提交货物,遭到A企业的拒绝,A企业要求B企业提供担保。B企业以自己的机床作为抵押,担保的价值为100万元,同时B企业请求C企业的分支机构甲为保证人,甲担保的价值为150万元,甲取得了C企业的担保授权委托书。6月20日,A、B签定了抵押合同,双方在抵押合同中约定,如B企业不能支付到期货款,该机床的所有权直接归A企业所有。6月22日,A、B企业办理了抵押物的登记手续。6月30日,A企业与甲分支机构签定了保证合同,双方在保证合同中约定,甲的保证方式为连带保证,但双方未约定保证期间和保证担保的范围。 7月1日,A企业按照合同约定向B企业提交了全部货物。B企业接到货物后,对标的物的数量和质量未提出异议,但由于经营状况不佳,7月10日(支付货款的最后期限)无力支付货款。7月12日,A企业向B企业要求行使抵押权,发现该机床已经被B企业转让,该转让行为A企业并不知道,另外,在A企业的要求下,B企业将80万元的补偿金全额支付给A企业。2006年6月1日,A企业要求C企业承担保证责任,支付其担保的150万元, C企业表示拒绝。A企业于是请求人民法院判定C企业履行保证责任。 要求: (1)A、B两个企业签定的买卖合同是否有效并说明理由。 (2)A企业在2005年6月5日是否可以中止履行合同并说明理由。 (3)A、B两个企业签定的抵押合同是否有效并说明理由。 (4)A企业与C企业的分支机构甲签订的保证合同是否有效并说明理由。 (5)在A、甲的保证合同中,保证期间如何界定 (6)B企业转让该机床的行为是否符合法律规定并说明理由。 (7)甲分支机构拒绝履行保证责任的理由是否成立并说明理由。
