|                               | Compton maintains disclosure controls and other procedures and internal control over financial reporting designed to ensure that information required to be disclosed in the reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Securitiesand Exchange Commission's (the "Commission") rules and forms. Compton's principal executive officer and principal financial officer evaluated the effectiveness of Compton's disclosure controls and procedures (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report and concluded that such disclosure controls and procedures are effective to ensure that information required to be disclosed by Compton in reports that it files or submits under the ExchangeAct is (i) recorded, processed, summarized, and reported within the time periods specified in the Commission's rules and forms and (ii) accumulated and communicated to Compton's management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure. |

|   | It should be noted that while Compton's principal executive officer and principal financial officer believe that Compton's disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that Compton's disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated, can provideonly reasonable, not absolute, assurance that the objectives of the control system are met. |
