style="font-family:inherit;font-size:12pt;">On December 30, 2011, we amended and renewed our senior secured revolving credit facility with JPMorgan Chase Bank, N.A. (the &#8220;Amended Credit Agreement&#8221;) which was set to expire on December 31, 2011.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">The Amended Credit Agreement increased our aggregate commitment amount from $20 million to $30 million, subject to collateral availability.  We also have a right to request from the lender, on an uncommitted basis, an increase of up to $20 million on the aggregate commitment (which could potentially increase the commitment amount to $50 million.)  Finally, the maturity date was extended to December 31, 2014 and the interest rate terms were amended.  Material terms of our senior secured revolving credit facility, as amended, include:</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-style:italic;">Borrowing Base</font><font style="font-family:inherit;font-size:12pt;">. At any time before the maturity of the facility, we may draw, repay and re-borrow amounts available under the borrowing base up to the maximum aggregate availability discussed above. Generally, the borrowing base equals the sum of (a) 80% of our eligible accounts receivable plus (b) 50% of the book value of our eligible general inventory (not to exceed 50% of the commitment amount at the time) plus (c) 75% of the book value of our eligible equipment inventory.  JPMorgan Chase Bank (the &#8220;Lender&#8221;) may adjust the borrowing base components may be adjusted if material deviations in the collateral are discovered in future audits of the collateral.</font></div><div style="line-height:120%;padding-top:6px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-style:italic;">Interest and Fees</font><font style="font-family:inherit;font-size:12pt;">.  Under the terms of the Amended Credit Agreement, we have the option of selecting the applicable variable rate for each revolving loan, or portion thereof, of either (a)&#160;LIBOR multiplied by the Statutory Reserve Rate (as defined in the Credit Agreement) to which the Lender is subject, with respect to this rate, for Eurocurrency funding, plus the Applicable Margin (&#8220;LIBOR-based&#8221;), or (b)&#160;CB Floating Rate, which is the Lender's Prime Rate less the Applicable Margin; provided, however, that no more than three LIBOR-based borrowings under the facility may be outstanding at any one time.  For purposes of the LIBOR-based interest rate, the Applicable Margin is 1.50%.  For purposes of the CB Floating Rate, the Applicable Margin is 1.25%.</font></div><div style="line-height:120%;text-align:justify;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:justify;text-indent:32px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Accrued interest is payable monthly on outstanding principal amounts, provided that accrued interest on LIBOR-based loans is payable at the end of each interest period, but in no event less frequently than quarterly. In addition, fees and expenses are payable in connection with our requests for letters of credit (generally equal to the Applicable Margin for LIBOR-related borrowings multiplied by the face amount of the requested letter of credit) and administrative and legal costs.</font></div><div style="line-height:120%;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">&#160;</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-style:italic;">Maturity</font><font style="font-family:inherit;font-size:12pt;">. The maturity date of the secured revolving credit facility under the Amended Credit Agreement is December 31, 2014, at which time all amounts borrowed under the facility will be due and outstanding letters of credit must be cash collateralized. The facility may be terminated early upon our request or the occurrence of an event of default.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-style:italic;">Security</font><font style="font-family:inherit;font-size:12pt;">. The obligations under the Amended Credit Agreement are secured by a first priority lien on all of our inventory and accounts and leases receivable, along with a first priority lien on a variable number of our leased compressor equipment the book value of which must maintain at a minimum a 2.00 to 1.00 commitment coverage ratio (such ratio being equal to (i) the amount of the borrowing base as of such date to (ii) the amount of the commitment as of such date.)</font><font style="font-family:inherit;font-size:12pt;font-style:italic;font-weight:bold;">&#32;</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-style:italic;">Covenants. </font><font style="font-family:inherit;font-size:12pt;">The Amended Credit Agreement contains customary representations and warranties, as well as </font></div><br><hr style="page-break-after:always"><a name="s9F2BF79B75DE135F5488B4A9E72872F2"></a><br><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">covenants which, among other things, limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make negative pledges; consolidate, merge or effect asset sales; or change the nature of our business.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-style:italic;">Events of Default and Acceleration. </font><font style="font-family:inherit;font-size:12pt;">The secured revolving credit facility contains customary events of default for credit facilities of this size and type, and includes, without limitation, payment defaults; defaults in performance of covenants or other agreements contained in the transaction documents; inaccuracies in representations and warranties; certain defaults, termination events or similar events; certain defaults with respect to any other Company indebtedness in excess of $50,000; certain bankruptcy or insolvency events; the rendering of certain judgments in excess of $150,000; certain ERISA events; certain change in control events and the defectiveness of any liens under the secured revolving credit facility.

In furtherance thereof, none of the terms of the Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the maximum rate permitted by applicable laws.  Maker shall never be liable for interest in excess of the maximum rate permitted by applicable laws.
