<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">All statements in this report (and oral statements made regarding the subjects of this communication) other than historical facts are forward-looking statements within the meaning of Section&nbsp;21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements rely on a number of assumptions concerning future events and are subject to a number of uncertainties and factors, many of which are outside the control of Archrock and the Partnership, which could cause actual results to differ materially from such statements. &#160;Forward-looking information includes, but is not limited to: statements regarding the expected benefits of the proposed transaction to the Partnership and its unitholders; the anticipated completion of the proposed transaction and the timing thereof; the expected future growth, dividends and distributions of the combined company; and plans and objectives of management for future operations.&#160; While Archrock believes that the assumptions concerning future events are reasonable, it cautions that there are inherent difficulties in predicting certain important factors that could impact the future performance or results of its business. Among the factors that could cause results to differ materially from those indicated by such forward-looking statements are: the failure to realize the anticipated costs savings, synergies and other benefits of the transaction; the possible diversion of management time on transaction-related issues; the risk that the requisite approvals to complete the transaction are not obtained; local, regional and national economic conditions and the impact they may have on Archrock, the Partnership and their customers; changes in tax laws that impact master limited partnerships; conditions in the oil and gas industry, including a sustained decrease in the level of supply or demand for oil or natural gas or a sustained decrease in the price of oil or natural gas; the financial condition of Archrock&#146;s and the Partnership&#146;s customers; any non-performance by customers of their contractual obligations; changes in customer, employee or supplier relationships resulting from the transaction; changes in safety, health, environmental and other regulations; the results of any reviews, investigations or other proceedings by government authorities; the results of any shareholder actions that may be filed relating to the restatement of Archrock&#146;s financial statements; the potential additional costs relating to Archrock&#146;s restatement, cost-sharing with Exterran Corporation and to addressing any reviews, investigations or other proceedings by government authorities or shareholder actions; and the performance of the Partnership.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">These forward-looking statements are also affected by the risk factors, forward-looking statements and challenges and uncertainties described in each of Archrock&#146;s and the Partnership&#146;s Annual Reports on Form&nbsp;10-K for the year ended December&nbsp;31, 2016, and those set forth from time to time in each party&#146;s filings with the SEC, which are available at www.archrock.com. Except as required by law, Archrock and the Partnership expressly disclaim any intention or obligation to revise or update any forward-looking statements whether as a result of new information, future events or otherwise.</font></p>
