Middle-Market Growth Business. We will seek to acquire one or more growth businesses with an enterprise value ranging from $300 million to $1 billion. We believe that our focus on businesses in this segment of the middle market will offer us a substantial number of potential business targets that we believe can achieve and maintain significant revenue and earnings growth. We do not intend to acquire start-up companies and, under our amended and restated certificate of incorporation, we will not be permitted to effectuate our initial business combination with another blank check company or a similar company with nominal operations
