Indemnification by and on Behalf of the Stockholders. Subject to the provisions of Section 7.05, the Stockholders jointly and severally agree to defend, indemnify and hold Dipper harmless from and against any and all losses, liabilities, damages, costs or expenses (including reasonable attorneys’ fees, penalties, and interest) payable to or for the benefit of, or asserted by, any party, resulting from, arising out of, or incurred as a result of: (a) the breach of any representation, warranty or covenant made by the Stockholders herein; or (b) any claim, whether made before or after the date of this Agreement, or any litigation, proceeding or governmental investigation, whether commenced before or after the date of this Agreement, arising out of the businesses of 21st Century prior to the Closing, or otherwise arising out of any act or occurrence prior to, or any condition or facts existing as of, the Closing, regardless of whether or not referred to on a Schedule to this Agreement or otherwise disclosed or known to Dipper as of the Closing. No claim by Dipper for indemnification by the Stockholders shall be made after one year has elapsed following the Closing Date except that a claim for indemnification may be made by Dipper with respect to a Third Party Claim until two years has elapsed following the Closing Date.

Subject to the provisions of Section 7.05, Dipper agrees to defend, indemnify and hold the Stockholders harmless from and against any and all losses, liabilities, damages, costs, or expenses (including reasonable attorneys’ fees, penalties and interest) payable to or for the benefit of, or asserted by, any party, resulting from, arising out of, or incurred as a result of the breach of any representation, warranty or covenant made by Dipper herein.

Notice of Claims. The Stockholders and Dipper shall give prompt written notice to each other of any claim by any party which might give rise to a claim by the Stockholders or Dipper against the other based upon the indemnity provisions contained herein, stating the nature and basis of the claim and the actual or

Exhibit 7.1

estimated amount thereof; provided, however, that failure to give such notice will not affect the obligation of the indemnifying party to provide indemnification in accordance with the provisions of this Article 7 unless, and only to the extent that, such indemnifying party is actually prejudiced thereby. In the event that any action, suit or proceeding is brought by a third party against the Stockholders or Dipper with respect to which the other party may have liability under the indemnification provisions contained herein, the indemnifying party shall have the right, at its sole cost and expense, to defend such action in the name or on behalf of the indemnified party and, in connection with any such action, suit or proceeding, the parties hereto agree to render to each other such assistance as may reasonably be required in order to ensure the proper and adequate defense of any such action, suit or proceeding; provided further, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate because of actual or potential differing interests between such indemnified party and any other party represented by such counsel. Neither party hereto shall make any settlement of any claim which might give rise to liability of the other party under the indemnification provisions contained herein without the written consent of such other party, which consent such other party covenants shall not be unreasonably withheld.

In the event of any liability of the Stockholders for indemnification, Dipper may elect to cause such liability to be satisfied in part or in whole by reducing pro rata the Dipper Stock issued to the Stockholders by the number of shares (rounded to the nearest whole number) equal to the amount of the Stockholders’ liability based on the published closing price for a share of Dipper Stock on the day such liability is quantified, and the certificates of Dipper Stock issued to the Stockholders shall bear a legend to that effect.
