At the same time, Sculley became locked in a battle with Microsoft's Bill Gates over the introduction of Windows 1.0, which had many similarities to the Mac GUI. Gates finally agreed to sign a statement to the effect that Microsoft would not use Mac technology in Windows 1.0--it said nothing of future versions of Windows, and Gates' lawyers made sure it was airtight. Apple had effectively lost exclusive rights to its interface design. This would prove to be an important document in future lawsuits between Apple and Microsoft, involving the Windows interface.

Jobs, who by now was being referred to as "interim CEO," made the keynote speech, and spoke of the company's upcoming aggressive advertising campaign, upcoming new Macs, and Rhapsody. He also announced an almost entirely new Board of Directors, including Larry Ellison, CEO of Oracle. But he saved the best for last. In a ground breaking decision, Jobs announced an alliance with Microsoft. In exchange for $150 million in Apple Stock, Microsoft and Apple would have a 5-year patent cross-license and, more importantly, a final settlement in the ongoing GUI argument. Microsoft agreed to pay an unreleased sum of additional funds to quiet the allegations that it had stolen Apple's intellectual property in designing its Windows OS. Microsoft also announced that Office '98, its popular office package, would be available for the Mac by years end.
