Not a lawyer, but you can have a contract to sign a contract. In fact this is normal in, for example, merger dealings and even smaller issues like buying a house: you first sign an agreement that says, after certain due diligence, you'll sign another agreement. The original agreement may or may not specify penalties for defaulting on it and not signing the second agreement, and if sued for breaching the first agreement, a court might not hold you to signing the second agreement. In this case, the first agreement definitely isn't enough to modify the company's articles of incorporation.
