[简答题]某市A区甲股份有限公司与该市B区乙有限责任公司于2005年4月3日签订了一份购销水泥的合同。合同约定：甲公司购买乙公司水泥1000吨，每吨价格400元，总货款40万元，交货时间为2005年5 10日，交货地点为甲公司指定的工地；如果一方违约，应当向守约方支付违约金2万元。合同订立后，公司向乙公司支付8万元预付款。2005年5月3日，乙公司发传真给甲公司，说由于公司流动资金紧张，没有从他处购得水泥，不能按期交货，要求延期4个月履行合同。甲公司拒绝延期履行合同，要求乙公司按期交货，乙公司予以拒绝，甲公司以乙公司违约为由诉至法院。　　在审理过程中，甲公司诉称：我公司与乙公司签订了水泥购销合同。合同约定：我公司购买乙公司水泥1000吨，每吨价格为400元，总货款40万元，交货时间为2005年5月10日，交货地点为我公司指定的工地；我公司向乙公司交纳预付款8万元；如果一方违约，应当向守约方支付违约金2万元。2005年5月3日，乙公司发传真给我公司，说由于公司流动资金紧张，没有从他处购得水泥，不能按期交货，要求延期4个月履行合同。我公司不同意延期履行合同，要求乙公司按期交货，但是遭到乙公司的拒绝。乙公司已经违约，故起诉要求：1．乙公司支付违约金2万元；2．乙公司退还预付款8万元；3．解除合同；4．乙公司承担本案的诉讼费用。　　乙公司辩称：我公司的确与甲公司达成了买卖水泥的合同，但是来曾考虑到资金紧张的问题，依据公平原则，不能让一个本来处于困境的公司承担不利后果，况且在履行期限尚未到来甲公司就要求我公司承担违约责任，与法不符，我公司并未违约。事实上，我公司并没有说不履行合同，只是延期4个月，这表明甲公司根本没有履行合同的诚意，甲公司已经违约在先，故要求：1．甲公司支付违约金2万元；2．我公司拒绝退还预付款8万元；3．甲公司承担本案的诉讼费用。　　根据以上案情制作一份判决书。
