                                 AND OPERATIONS


ITEM 1.01.        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Amendments to Second Amended and Restated Credit Agreement.

                  (i) On June 22, 2006, we entered into a Third Amendment (the
"Third Amendment") to our Second Amended and Restated Credit Agreement (the
"Credit Agreement") with General Electric Capital Corporation ("GECC"). The
Third Amendment amended the financial covenants of our Credit Agreement to
increase to $15.0 million from $10.0 million the maximum amount of capital
expenditure we are permitted to make during the year ended December 31, 2006.

                  (ii) On August 14, 2006, we entered into a Fourth Amendment
(the "Fourth Amendment") to our Credit Agreement with GECC. Among other
amendments, the Fourth Amendment

                  o   Increased the revolving credit facility by $15.0 million
                      or a facility limit of up to $30.0 million, but not
                      exceeding a borrowing base of 85% of the book value of
                      eligible accounts receivable, less any reserves GECC may
                      establish from time to time,

                  o   Increased the lending limit on the capital expenditure
                      loan facility by $20.0 million or a lending limit of up to
                      $25.0 million, but not exceeding the lesser of 80% of the
                      hard costs of eligible capital equipment and 75% of the
                      forced liquidation value of eligible capital equipment,
                      subject to adjustment by GECC. The date through which
                      capital expenditure loans are available to be made under
                      the Credit Agreement was extended by six months through
                      June 16, 2007,

                  o   Amended further the maximum amount of capital expenditures
                      we are permitted to make as follows:

                                              ------                                 per Period

                        Year Ended December 31, 2006                               $45.0 million

                        Year Ended December 31, 2007                               $50.0 million

                        Each Year Ended December 31 thereafter                     $40.0 million
</TABLE>

                                       2
<PAGE>


                  o   The repayment provisions of the capital expenditure loan
                      were amended to provide that the capital expenditure loan
                      is to be repaid in eight quarterly installments commencing
                      January 1, 2007 and continuing thereafter with the first
                      two installments to be equal to $250,000 and the last six
                      installments to be equal to the sum of $250,000 plus
                      1/20th of the principal amount of the capital expenditure
                      loan funded on or after August 14, 2006. A final ninth
                      installment is due and payable on December 16, 2008 and is
                      to be in the amount of the entire remaining balance of the
                      capital expenditure loan.

                  o   The repayment provisions of the term loan were amended to
                      provide that the final payment on the term loan is due and
                      payable on December 16, 2008 rather than December 31,
                      2008.

                  o   The interest rate on borrowings under the Credit Agreement
                      as entered into on December 16, 2005 is based on an index
                      rate, as defined, plus an interest rate margin. The Credit
                      Agreement provides that the interest rate margins are
                      adjusted on a quarterly basis based on our ratio of our
                      funded debt to EBITDA for the trailing twelve months prior
                      to the determination. The Fourth Amendment provides that
                      the interest rate margins are amended to provide for the
                      addition of two lower-bracket interest rate margins
                      ranging, as applicable to the revolving loan, term loan
                      and capital expenditure loan, from 0.5% and 0.75% to 2.0%
                      and 2.25% based upon our ratio of funded debt to EBITDA
                      for the period being equal to a ratio of less than 0.5 to
                      1.0 and less than 1.0 to 1.0, respectively.

                  o   The Credit Agreement was further amended to enable us to
                      request and the lenders agreed to provide or enable the
                      issuance to us of letters of credit of up to one year
                      duration and in amounts up to the lesser of $2.0 million
                      and the amount available to be borrowed under the
                      revolving credit facility of the Credit Agreement.

                  Reference is made to the Credit Agreement filed as an exhibit
to our Current Report on Form 8-K for December 16, 2005 and the First and Second
Amendments thereto filed as exhibits to our Current Report on Form 8-K for April
18, 2006 and to Exhibits 10.1 and 10.2 to this Current Report on Form 8-K for a
further statement of the terms and conditions of the credit facility.

ITEM 1.01.        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Amendments to Second Amended and Restated Credit Agreement.

                  (i) On June 22, 2006, we entered into a Third Amendment (the
"Third Amendment") to our Second Amended and Restated Credit Agreement (the
"Credit Agreement") with General Electric Capital Corporation ("GECC"). The
Third Amendment amended the financial covenants of our Credit Agreement to
increase to $15.0 million from $10.0 million the maximum amount of capital
expenditure we are permitted to make during the year ended December 31, 2006.

                  (ii) On August 14, 2006, we entered into a Fourth Amendment
(the "Fourth Amendment") to our Credit Agreement with GECC. Among other
amendments, the Fourth Amendment

                  o   Increased the revolving credit facility by $15.0 million
                      or a facility limit of up to $30.0 million, but not
                      exceeding a borrowing base of 85% of the book value of
                      eligible accounts receivable, less any reserves GECC may
                      establish from time to time,

                  o   Increased the lending limit on the capital expenditure
                      loan facility by $20.0 million or a lending limit of up to
                      $25.0 million, but not exceeding the lesser of 80% of the
                      hard costs of eligible capital equipment and 75% of the
                      forced liquidation value of eligible capital equipment,
                      subject to adjustment by GECC. The date through which
                      capital expenditure loans are available to be made under
                      the Credit Agreement was extended by six months through
                      June 16, 2007,

                  o   Amended further the maximum amount of capital expenditures
                      we are permitted to make as follows:
Period                        Maximum Capital Expenditure
                                              ------                                 per Period
                                                                                     ----------
Year Ended December 31, 2006                               $45.0 million

                        Year Ended December 31, 2007                               $50.0 million

                        Each Year Ended December 31 thereafter                     $40.0 million
2
o   The repayment provisions of the capital expenditure loan
                      were amended to provide that the capital expenditure loan
                      is to be repaid in eight quarterly installments commencing
                      January 1, 2007 and continuing thereafter with the first
                      two installments to be equal to $250,000 and the last six
                      installments to be equal to the sum of $250,000 plus
                      1/20th of the principal amount of the capital expenditure
                      loan funded on or after August 14, 2006. A final ninth
                      installment is due and payable on December 16, 2008 and is
                      to be in the amount of the entire remaining balance of the
                      capital expenditure loan.

                  o   The repayment provisions of the term loan were amended to
                      provide that the final payment on the term loan is due and
                      payable on December 16, 2008 rather than December 31,
                      2008.

                  o   The interest rate on borrowings under the Credit Agreement
                      as entered into on December 16, 2005 is based on an index
                      rate, as defined, plus an interest rate margin. The Credit
                      Agreement provides that the interest rate margins are
                      adjusted on a quarterly basis based on our ratio of our
                      funded debt to EBITDA for the trailing twelve months prior
                      to the determination. The Fourth Amendment provides that
                      the interest rate margins are amended to provide for the
                      addition of two lower-bracket interest rate margins
                      ranging, as applicable to the revolving loan, term loan
                      and capital expenditure loan, from 0.5% and 0.75% to 2.0%
                      and 2.25% based upon our ratio of funded debt to EBITDA
                      for the period being equal to a ratio of less than 0.5 to
                      1.0 and less than 1.0 to 1.0, respectively.

                  o   The Credit Agreement was further amended to enable us to
                      request and the lenders agreed to provide or enable the
                      issuance to us of letters of credit of up to one year
                      duration and in amounts up to the lesser of $2.0 million
                      and the amount available to be borrowed under the
                      revolving credit facility of the Credit Agreement.
