The Alagasco Loan Agreement contains nonfinancial covenants, including limitations on certain types of acquisitions, investments and sales of property. The Alagasco Loan Agreement also contains a financial covenant limiting the Company's debt to 70% of its capitalization.

The Alagasco Loan Agreement has a credit commitment of $150.0. Under certain terms and conditions, the Company may request an increase of up to $50.0 in the credit commitment. The Alagasco Loan Agreement also provides for letters of credit in an aggregate amount up to $15.0, and swingline loans in an aggregate amount up to $15.0.
