Other Events. On August 13, 1997, the Company, through a new subsidiary, acquired the assets and business of Michigan-based Sub-Surface Construction Co. ("Sub-Surface") for $15.4 million in cash plus the assumption of certain liabilities. Sub-Surface primarily constructed underground natural gas distribution pipelines, service lines and associated facilities. Through the Company's new subsidiary, SEMCO Energy Construction Co. ("SEMCO Construction"), the Company now provides these construction services, which are strongly related to the Company's core energy business expertise. Sub-Surface was a privately held construction company headquartered in Comstock Park, Michigan, and owned by Stewart Kniff. Sub-Surface operated five facilities in Michigan and employed at the peak of the construction season nearly 450 employees, many of whom were union field employees. Sub-Surface had annual revenues of approximately $33 million, and had a long relationship with natural gas distribution companies throughout Michigan. SEMCO Construction has taken over Sub-Surface's business with essentially the same employees and will operate under the Sub-Surface name. SEMCO Construction intends to continue Sub-Surface's high-quality construction services to natural gas distribution companies. These services include installation of new distribution pipelines, mains and service lines to deliver natural gas as new customers demand service. SEMCO Construction will also continue significant maintenance and replacement services for existing gas mains and service lines. The Company hopes to grow this business in Michigan and surrounding states. Infrastructure work for electric, telephone, and cable services is a possible extension of the business. -2- Item 7.(c) Exhibits. 2.(i) Asset Purchase Agreement dated August 9, 1997, between Sub-Surface Construction Co., Stewart Kniff and SEMCO Energy Construction Co. 2.(ii) First Amendment to Asset Purchase Agreement. 2.(iii) Amendment to Leased Equipment Purchase Agreements and Asset Purchase Agreement. 2.(iv) List of Schedules and Exhibits. 2.(v) Agreement to Furnish Schedules and Exhibits. 27.
