• certain factors discussed elsewhere in this Quarterly Report.

     The list of factors is not exhaustive, and new factors may emerge or changes to these factors may occur that would impact our business.  Additional information regarding these and other factors may be contained in our filings with the SEC, especially on Forms 10-K, 10-Q and 8-K.  All such risk factors are difficult to predict and are subject to material uncertainties that may affect actual results and may be beyond our control.  The forward-looking statements included in this report are made only as of the date of this report, and we undertake no obligation to update any of these forward-looking statements to reflect subsequent events or circumstances except to the extent required by applicable law.

QUICKSILVER GAS SERVICES LP
NOTES TO CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS
UNAUDITED

1. ORGANIZATION AND DESCRIPTION OF BUSINESS

     Organization — Quicksilver Gas Services LP (“KGS”) is a Delaware limited partnership formed in January 2007 for the purpose of completing a public offering of common units and concurrently acquiring midstream assets.  Our general partner is owned by Quicksilver.

     On December 10, 2009, we entered into an underwriting agreement to offer 4,000,000 common units at a price to the public of $21.10 per common unit.  The total net proceeds that we received from the secondary offering during December 2009, before expenses, were approximately $81 million.  In January 2010, the underwriters exercised their option to purchase an additional 549,200 common units, which resulted in additional proceeds of $11.1 million.  During December 2009, we used the proceeds from our secondary offering to temporarily pay down our Credit Facility before finalizing our purchase of the Alliance Midstream Assets for $84.4 million during 2010.  Also in January 2010, we used $11 million from the sale of additional units to the underwriters to pay down our Credit Facility.

     As of June 30, 2010, our ownership is as follows:

	Ownership Percentage
	Quicksilver			Public			Total
General partner interest		1.6	%		-			1.6	%
Limited partner interest:
Common unitholders		19.7	%		39.0	%		58.7	%
Subordinated unitholders		39.7	%		-			39.7	%
Total interests		61.0	%		39.0	%		100.0	%

     Neither KGS nor our general partner has any employees.  Employees of Quicksilver have been seconded to our general partner pursuant to a services and secondment agreement.  The seconded employees, including field operations personnel, general and administrative personnel and a vice president, operate or directly support our midstream operations.

     In July 2010, we announced that Quicksilver, the owner of our general partner, entered into a definitive agreement to sell all of its interest in us to Crestwood.  At the closing of the Crestwood Transaction, Quicksilver will convey all of its ownership of us to Crestwood.  We do not expect the transaction to have any direct impact to our historical financial statements as previously reported.  However, effective at the closing date of the transaction, we expect the following significant matters to occur:

• recognition of approximately $4.4 million of unrecognized costs associated with equity-based compensation of KGS phantom units;

• acceleration of amounts due under our Credit Facility, which we expect will be replaced by another credit facility;

• termination of our omnibus agreement with Quicksilver;

• termination of our services and secondment agreement with Quicksilver which will be replaced, on a temporary basis, with a transition services agreement;

• extension of the terms of all gathering agreements with Quicksilver to 2020;

• change to a fixed gathering rate of $0.55 per Mcf at the Alliance System to replace the variable rate which has a range of $0.40 to $0.55 per Mcf.

     More information regarding the Crestwood Transaction is contained in our 2010 Highlights discussion within Management’s Discussion and Analysis in Item 2 of Part I of this Quarterly Report.

     Description of Business — We are engaged in the gathering, processing, compression and treating of natural gas and the delivery of NGLs produced from the Barnett Shale formation in the Fort Worth Basin located in Texas.  We provide services under contracts, whereby we receive fees for performing gathering, processing, compression and treating services.  We do not take title to the natural gas or associated NGLs thereby avoiding direct commodity price exposure.

9

Our assets include or formerly included:

Cowtown System

The Cowtown System, located principally in Hood and Somervell counties in the southern portion of the Fort Worth Basin, which includes:

- the Cowtown Pipeline, consisting of a gathering system and related gas compression facilities. This system gathers natural gas produced by our customers and delivers it to the Cowtown and Corvette Plants for processing;

- the Cowtown Plant, consisting of two natural gas processing units with a total capacity of 200 MMcfd that extract NGLs from the natural gas stream and deliver customers’ residue gas and extracted NGLs to unaffiliated pipelines for sale downstream; and

- the Corvette Plant, placed in service during 2009, consisting of a 125 MMcfd natural gas processing unit that extracts NGLs from the natural gas stream and delivers customers’ residue gas and extracted NGLs to unaffiliated pipelines for sale downstream.

Lake Arlington Dry System

The LADS, located in eastern Tarrant County, consists of a gas gathering system and related gas compression facility with capacity of 180 MMcfd.  This system gathers natural gas produced by our customers and delivers it to unaffiliated pipelines for sale downstream.

Alliance System

During 2010, we completed the purchase of the Alliance Midstream Assets, from Quicksilver for a purchase price of $84.4 million, which with subsequent additions, we refer to as the Alliance System.  The Alliance System consists of a gathering system and related compression facility with a capacity of 300 MMcfd, an amine treating facility with capacity of 360 MMcfd and a dehydration treating facility with capacity of 300 MMcfd.  This system gathers natural gas produced by our customers and delivers it to unaffiliated pipelines for sale downstream.  The majority of the Alliance Midstream Assets operations commenced service in September 2009, although less significant operations had been conducted prior to that time.  Because the purchase of the Alliance Midstream Assets was conducted among entities under common control, GAAP requires the inclusion of the Alliance System’s revenue and expenses in our income statements for all periods presented.  The following summarizes the impact of this inclusion:

Hill County Dry System
As more fully described in Note 2, our financial information through November 2009 also included the operations of a gathering system in Hill County, Texas.  The HCDS gathers natural gas and delivers it to unaffiliated pipelines for further transport and sale downstream.  As of November 2009, the assets, liabilities, revenue and expenses directly attributable to the HCDS for the periods prior to November 2009 have been retrospectively reported as discontinued operations based upon the execution of the Repurchase Obligation Waiver.  The HCDS had previously been subject to a repurchase obligation since its 2007 sale to Quicksilver.

     All repurchase obligations to Quicksilver were concluded by December 31, 2009.  Notes 2 and 4 to the consolidated financial statements in our 2009 Annual Report on Form 10-K contain more information regarding the Repurchase Obligation Waiver.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation — The accompanying condensed consolidated interim financial statements and related notes present the financial position, results of operations, cash flows and changes in partners’ capital of our natural gas gathering and processing assets.  In management’s opinion, all necessary adjustments to fairly present our results of operations, financial position and cash flows for the periods presented have been made and all such adjustments are of a normal and recurring nature.

     Use of Estimates — The preparation of financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amount of assets, liabilities, revenue and expenses and disclosure of contingent assets and liabilities that exist at the date of the financial statements.  Estimates and judgments are based on information available at the time such estimates and judgments are made.  Although management believes the estimates are appropriate, actual results can differ from those estimates.

     Certain disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted.  Accordingly, these financial statements should be read in conjunction with our consolidated financial statements and notes thereto included in our 2009 Annual Report on Form 10-K.

     Discontinued Operations — In November 2009, Quicksilver and our general partner mutually agreed to waive both parties’ rights and obligations to transfer ownership of the HCDS from Quicksilver to us, which we refer to as the Repurchase Obligation Waiver.  The Repurchase Obligation Waiver caused derecognition of the assets and liabilities directly attributable to the HCDS, most significantly the property, plant and equipment and repurchase obligation, beginning in November 2009.  In addition, the Repurchase Obligation Waiver caused the elimination of the HCDS’ revenue and expenses from our consolidated results of operations beginning in November 2009.  The assets, liabilities, revenue and expenses directly attributable to the HCDS for the periods prior to November 2009 have been retrospectively reported as discontinued operations.

     Our 2007 sale of the HCDS to Quicksilver was not treated as a sale for accounting purposes because we operated it and originally intended to repurchase the assets.  Accordingly, the original cost and subsequently incurred costs were recognized in both our property, plant and equipment and our repurchase obligations to Quicksilver prior to their reclassification to discontinued operations.  Similarly, our results of operations included the revenue and expenses for these operations prior to their reclassification to discontinued operations.

Recently Issued Accounting Standards

     Accounting standard-setting organizations frequently issue new or revised accounting rules.  We regularly review all new pronouncements to determine their impact, if any, on our financial statements.  No pronouncements materially affecting our financial statements have been issued since the filing of our 2009 Annual Report on Form 10-K.

3. PARTNERS’ CAPITAL AND DISTRIBUTIONS

     Our Partnership Agreement requires that we make distributions within 45 days after the end of each quarter to unitholders of record on the applicable record date selected by the general partner.

     The following table presents cash distributions attributable to quarters ended in 2010 and 2009:

12

	Attributable to the	Per Unit		Total Cash

(4)	Total cash distribution includes an Incentive Distribution Rights amount of approximately $219,000 to the general partner
(5)	Total cash distribution includes an Incentive Distribution Rights amount of approximately $90,000 to the general partner

     The subordination period will end, and the subordinated units will convert to an equal number of common units, when KGS has earned and paid at least $0.30 per quarter on each common unit, subordinated unit and general partner unit for any three consecutive years, which we expect will occur in the fourth quarter of 2010.

4. DISCONTINUED OPERATIONS

     Our Credit Facility includes an “accordion feature” that permits us to expand our borrowing capacity from $320 million to $350 million.  The weighted-average interest rate as of June 30, 2010 was 3.5%.  For a more complete description of our indebtedness, see Note 7 to the consolidated financial statements in our 2009 Annual Report on Form 10-K.

     As more fully discussed in our Management’s Discussion and Analysis in Item 2 of Part I of this Quarterly Report, we expect the Crestwood Transaction will cause the Credit Facility to terminate and for a new credit facility to be established by Crestwood.  As part of the Crestwood Transaction, Crestwood will acquire the Subordinated Note to Quicksilver.

7. ASSET RETIREMENT OBLIGATIONS

     Activity for asset retirement obligations is as follows:

	June 30, 2010
	(In thousands)
Beginning asset retirement obligations as reported at December 31, 2009	$	7,654
Alliance Midstream Asset obligations at December 31, 2009		1,265

Ending asset retirement obligations at June 30, 2010	$	9,425

As of June 30, 2010, no assets are legally restricted for use in settling asset retirement obligations.

8. EQUITY-BASED COMPENSATION

     Awards of phantom units have been granted under our amended 2007 Equity Plan.  The following table summarizes information regarding 2010 phantom unit activity:

	Payable in cash					Payable in units
				Weighted					Weighted
				Average Grant					Average Grant
	Units			Date Fair Value		Units			Date Fair Value
Unvested phantom units - January 1, 2010		33,240		$	20.90		485,672		$	12.75
Vested		(1,956	)		18.94		(179,886	)		13.74
Issued		-			-		211,600			21.15
Cancelled		-			-		(763	)		17.52
Unvested phantom units - June 30, 2010		31,284		$	20.82		516,623		$	15.83

     At January 1, 2010, KGS had total unvested compensation cost of $2.9 million related to phantom units.  KGS recognized compensation expense of approximately $1.8 million during the six months ended June 30, 2010, including $0.2 million related to Quicksilver equity grants issued to employees seconded to KGS.  Grants of phantom units during the six months ended June 30, 2010 had an estimated grant date fair value of $4.5 million.  KGS had unearned compensation expense of $4.4 million at

14

June 30, 2010 that is scheduled to be recognized in expense through December 2012.  Phantom units that vested during the six months ended June 30, 2010 had a fair value of $2.5 million on their vesting date.

     On January 4, 2010, KGS awarded annual equity grants totaling 211,600 phantom units to the non-management directors, executive officers of KGS’ general partner and employees seconded to KGS.  Each phantom unit will settle in KGS units and had a grant date fair value of $21.15, which will be recognized over the vesting period of three years except for grants to non-employee directors of our general partner in lieu of cash compensation, which vest after one year.  At June 30, 2010, 593,271 units were available for issuance under the amended 2007 Equity Plan.

     For a more complete description of KGS’ Equity Plan, see Note 11 to the consolidated financial statements in our 2009 Annual Report on Form 10-K.

     At the closing of the Crestwood Transaction, we expect to recognize approximately $4.4 million attributable to acceleration of equity-based compensation in KGS, due to the change in control of the general partner and in accordance with the terms of our amended 2007 Equity Plan.

9. INCOME TAXES

     No provision for federal income taxes related to KGS’ results of operations is included in the accompanying unaudited condensed consolidated interim financial statements as such income is taxable directly to the partners holding interests in KGS.

     The closing of the Crestwood Transaction will cause a technical termination of KGS as defined by the Internal Revenue Code.  One of the significant consequences of a technical termination is its impact on the partnership’s filing requirement for federal income tax purposes.  Generally, the partnership taxable year closes with respect to all partners on the date on which the current KGS partnership terminates.  A terminated partnership must file a federal income tax return for the short period ending on the date of the sale that resulted in the technical termination.  A second short period return is then required to be filed for the remainder of the taxable year of that new partnership.

     Quicksilver does not expect to owe consolidated Texas margin tax for 2009 and, accordingly, we do not expect to make a cash payment for its 2009 liability for Texas margin tax, based upon Texas filing rules.  All effects of the 2009 Texas margin tax calculation are captured in deferred income taxes.  However, after the technical termination, we will no longer be included in the combined report of Quicksilver, therefore we may owe Texas margin tax for 2010 and subsequent years.

     For more information about our income taxes, see Note 10 to the consolidated financial statements in our 2009 Annual Report on Form 10-K.

10. COMMITMENTS AND CONTINGENT LIABILITIES

     For a description of our commitments and contingencies see Note 9 to the consolidated financial statements in our 2009 Annual Report on Form 10-K.

11. RELATED-PARTY TRANSACTIONS

     We routinely conduct business with Quicksilver and its affiliates.  For a more complete description of our agreements with Quicksilver, see Note 2 and Note 12 to the consolidated financial statements in our 2009 Annual Report on Form 10-K.

     During the quarter and six months ended June 30, 2010, Quicksilver accounted for more than 90% of our total revenue.  All cash disbursements for our operations and maintenance expenses and general and administration expenses for the quarter and six months ended June 30, 2010 were paid to Quicksilver, which processes such amounts on our behalf.

     With the purchase of the Alliance Midstream Assets, we also entered into an agreement with Quicksilver to lease pipeline assets attached to the Alliance System that we did not purchase.  We have recognized $1.1 million of expense related to this agreement during the six months ended June 30, 2010.

     Note 1 contains additional information about changes to our relationship with Quicksilver upon closing of the Crestwood Transaction.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

     The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated interim financial statements, and notes thereto, and the other financial data included elsewhere in this Quarterly Report.  The following discussion should also be read in conjunction with our audited consolidated financial statements, and notes thereto, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2009 Annual Report on Form 10-K.

Overview

     We are a growth-oriented Delaware limited partnership engaged in gathering, processing, compression and treating of natural gas and delivery of NGLs produced from the Barnett Shale geologic formation of the Fort Worth Basin located in North Texas.  We began operations in 2004 to provide midstream services primarily to Quicksilver as well as to other natural gas producers in this area.  During the quarter and six months ended June 30, 2010, 94% of our total gathering and 88% of our processing volumes were comprised of natural gas owned or controlled by Quicksilver.

Our Operations

     The results of our operations are significantly influenced by the volumes of natural gas gathered and processed through our systems.  We gather, process, compress and treat natural gas pursuant to contracts under which we receive fees.  We do not take title to the natural gas or associated NGLs that we gather and process, and therefore, we avoid direct commodity price exposure.  However, a sustained decline in commodity prices could result in our customers reducing their production volumes which would cause a resulting decrease in our revenue.  Our contracts provide relatively stable cash flows, but little upside in higher commodity price environments.  All of our natural gas volumes gathered and processed during the quarter and six months ended June 30, 2010 were subject to fee-based contracts.

Operational Measurement

     Our management uses a variety of financial and operational measures to analyze our performance.  We view these measures as important factors affecting our profitability and unitholder value and therefore we review them monthly for consistency and to identify trends in our operations.  These performance measures are outlined below:

     Volume – We must continually obtain new supplies of natural gas to maintain or increase throughput volumes on our gathering and processing systems.  We routinely monitor producer activity in the areas we serve to identify new supply opportunities.  Our ability to achieve these objectives is impacted by:

• the level of successful drilling and production activity in areas where our systems are located;

• our ability to compete with other midstream companies for production volumes; and

• our pursuit of new opportunities.

     Adjusted Gross Margin – We use adjusted gross margin information to evaluate the relationship between our gathering and processing revenue and the cost of operating our facilities, including our general and administrative overhead.  Adjusted gross margin is not a measure calculated in accordance with GAAP as it does not include deductions for expenses such as interest and income tax which are necessary to maintain our business.  In measuring our operating performance, adjusted gross margin should not be considered an alternative to, or more meaningful than, net income or operating cash flow determined in accordance with GAAP.  Our adjusted gross margin may not be comparable to a similarly titled measure of another company because other entities may not calculate adjusted gross margin in the same manner.  A reconciliation of adjusted gross margin to amounts reported under GAAP is presented in “Results of Operations.”

     Operating Expenses – We consider operating expenses in evaluating the performance of our operations.  These expenses are comprised primarily of direct labor, insurance, property taxes, repair and maintenance expense, utilities and contract services, and are largely independent of the volumes through our systems, but may fluctuate depending on the scale of our operations during a specific period.  Our ability to manage operating expenses has a significant impact on our profitability and ability to pay distributions.

     EBITDA – We believe that EBITDA is a widely accepted financial indicator of a company’s operational performance and its ability to incur and service debt, fund capital expenditures and make distributions.  EBITDA is not a measure calculated in accordance with GAAP, as it does not include deductions for items such as depreciation, interest and income taxes, which are necessary to maintain our business.  EBITDA should not be considered an alternative to net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP.  EBITDA calculations may vary among entities,

16

so our computation may not be comparable to EBITDA measures of other entities.  In evaluating EBITDA, we believe that investors should also consider, among other things, the amount by which EBITDA exceeds interest costs, how EBITDA compares to principal payments on debt and how EBITDA compares to capital expenditures for each period.  A reconciliation of EBITDA to amounts reported under GAAP is presented in “Results of Operations.”

     EBITDA is also used as a supplemental performance measure by our management and by external users of our financial statements such as investors, commercial banks, research analysts and others, to assess:

• financial performance of our assets without regard to financing methods, capital structure or historical cost basis;

• our operating performance as compared to those of other companies in the midstream industry without regard to financing methods, capital structure or historical cost basis; and

• the viability of acquisitions and capital expenditure projects and the rates of return on investment opportunities.

2010 Highlights

•	During 2010, we completed the purchase of the Alliance Midstream Assets, located in Tarrant and Denton counties of Texas, from Quicksilver for $84.4 million.  Gathered volumes on the Alliance System in the six months ended June 30, 2010 averaged 129 MMcfd.
•	In January 2010, the underwriters of our secondary offering exercised their option to purchase an additional 549,200 common units, which resulted in additional proceeds of $11.1 million.  We used $11 million from the sale of the additional units to pay down our Credit Facility.
•	During July 2010, Quicksilver agreed to sell all of Quicksilver’s interests in us to Crestwood.  The acquired interests will include a 100% ownership interest in Quicksilver Gas Services Holdings LLC, which owns (a) 5,696,752 common units of KGS, (b) 11,513,625 subordinated limited partner units of KGS and (c) 100% of the outstanding membership interests in our General Partner including 469,944 general partner units in KGS and 100% of the outstanding incentive distribution rights.  Crestwood will also acquire the Subordinated Note to Quicksilver.  In exchange, Quicksilver will receive $701 million in cash at closing and up to $72 million in future earn-out payments due in 2012 and 2013.  The Crestwood Transaction is expected to close in October 2010, subject to customary closing conditions.
	Under the agreements governing the Crestwood Transaction, Quicksilver has agreed for two years not to solicit our employees and not to compete with us with respect to gathering, treating and processing of natural gas and the transportation of natural gas liquids in Denton, Hood, Somervell, Johnson, Tarrant, Parker, Bosque and Erath Counties in Texas.  Quicksilver will be entitled to appoint a director to our General Partner’s Board of Directors until the later of the second anniversary of the closing and such time as Quicksilver generates less than 50% of our consolidated revenue in any fiscal year.  We also expect that our current independent directors will continue as directors after the closing of the Crestwood Transaction.
	In connection with the closing of the Crestwood Transaction, Quicksilver will provide us with transitional services on a temporary basis on customary terms.  We expect that more than 100 experienced midstream employees who had previously been seconded to us will become our employees.  Quicksilver and we will also enter into an agreement for the joint development of areas governed by certain of our existing commercial agreements and amend certain of our existing commercial agreements, most significantly to extend the terms of all Quicksilver gathering agreements to 2020 and to establish a fixed gathering rate of $0.55 Mcf at the Alliance System.

The following table summarizes the changes in our revenue:

	Gathering		Processing			Other			Total
	(In thousands)
Revenue for the three months ended June 30, 2009	$	14,120	$	8,995		$	225		$	23,340
Volume changes		4,685		(1,667	)		-			3,018
Price changes		940		121			(225	)		836
Revenue for the three months ended June 30, 2010	$	19,745	$	7,449		$	-		$	27,194

     Total Revenue and Volumes — The increase in revenue was principally due to approximately $7.1 million in higher revenue due to increases volumes on the Alliance System.  The increase in revenue was partially offset by approximately $3.0 million in reduced revenue due to lower volumes at Cowtown System and LADS, primarily due to Quicksilver’s capital focus being in the Alliance area since June 30, 2009.

     Operations and Maintenance Expense — The increase in operations and maintenance expense was mainly due to the $1.2 million of higher costs attributable to the expansion of the Alliance System due to the addition of a compression facility and an expanded gathering system.  The increase was partially offset by lower costs to operate our plant facilities on the Cowtown System.

     General and Administrative Expense — The increase in general and administrative expense was due to equity compensation expense, as a result of additional phantom unit grants in January 2010.  This increase was partially offset by

18

lower legal expenses.  General and administrative expense includes $0.6 million and $0.4 million of equity-based compensation expense for the quarters ended June 30, 2010 and 2009, respectively.

     Adjusted Gross Margin and EBITDA — Adjusted gross margin and EBITDA increased primarily as a result of the increase in revenue described above.  As a percentage of revenue, adjusted gross margin and EBITDA increased from 67% in the 2009 quarter to 69% in the 2010 quarter.

     Depreciation and Accretion Expense — Depreciation and accretion expense increased primarily as a result of continuing expansion of our asset base, which included the expansion of the Alliance System.

     Interest Expense — Interest expense increased primarily due to the increases in the borrowings under our Credit Facility, partially offset by the absence of any repurchase obligations.  During December 2009, we used $80.5 million of proceeds from our secondary offering to temporarily pay down our Credit Facility.  During January 2010, we borrowed $95 million to purchase the Alliance Midstream Assets and repaid $11 million upon the underwriters’ exercise of their over-allotment option.

The following table summarizes the details of interest expense for the three months ended June 30, 2010 and 2009.  With the conclusion of our repurchase obligations during 2009, we have no interest expense for such items in 2010.

Revenue for the six months ended June 30, 2010	$	37,249	$	14,684		$	-		$	51,933

     Total Revenue and Volumes — The increase in revenue was principally due to approximately $12.1 million in higher revenue due to increased volumes on the Alliance System.  The increase in revenue was partially offset by approximately $7.1 million in lower revenue due to reduced volumes at Cowtown System and LADS, primarily due to Quicksilver’s capital focus being in the Alliance area since June 30, 2009.  In addition, an increase in revenue relates to higher fees associated with the commencement of compression and treating services on the Alliance System beginning in September 2009 as well as additional compression assets that were placed into service on the Cowtown System during the 2009 period.  We expect our gathered volumes to be between 355 MMcfd and 375 MMcfd for the remainder of 2010, which will yield average gathered volumes for 2010 of between 330 MMcfd and 340 MMcfd.

     Operations and Maintenance Expense — The increase in operations and maintenance expense was mainly due to the $3.4 million of higher costs attributable to the expansion of the Alliance System due to the addition of a compression facility and an expanded gathering system.

     General and Administrative Expense — The increase in general and administrative expense was due to higher advertising cost and equity compensation expense, as a result of additional phantom unit grants in January 2010.  General and

administrative expense includes $1.3 million and $0.9 million of equity-based compensation expense for the six months ended June 30, 2010 and 2009, respectively.  Upon closing of the Crestwood Transaction, we expect that our general and administrative expenses will increase due to our bearing the full burden of the general and administrative costs for Crestwood executives.  We are presently unable to determine the extent to which we expect general and administrative to increase.

     Adjusted Gross Margin and EBITDA — Adjusted gross margin and EBITDA decreased primarily as a result of the increase in expenses described above.  As a percentage of revenue, adjusted gross margin and EBITDA decreased from 68% in the 2009 period to 64% in the 2010 period, primarily due to the increase in operations and maintenance expense associated with our current scale of operations and higher general and administrative expense, which were partially offset by the increase in revenue.

     Depreciation and Accretion Expense — Depreciation and accretion expense increased primarily as a result of continuing expansion of our asset base, which included the expansion of the Alliance System.

     Interest Expense — Interest expense increased primarily due to the increases in the borrowings under our Credit Facility, partially offset by the absence of any repurchase obligations.  During December 2009, we used $80.5 million of proceeds from our secondary offering to temporarily pay down our Credit Facility.  During January 2010, we borrowed $95 million to purchase the Alliance Midstream Assets and repaid $11 million upon the underwriters’ exercise of their over-allotment option.

The following table summarizes the details of interest expense for the six months ended June 30, 2010 and 2009.  With the conclusion of our repurchase obligations during 2009, we have no interest expense for such items in 2010.

Liquidity and Capital Resources

     The volumes of natural gas that we gather and process are dependent upon the natural gas volumes produced by our customers, which may be affected by prevailing natural gas prices, their derivative programs, the availability and cost of capital, their level of successful drilling activity and other factors beyond their control.  We cannot predict future changes to natural gas prices or how any such pricing changes will influence producers’ behaviors.  If reduced drilling and development conditions were to persist or worsen over a prolonged period of time, we could experience a reduction in volumes through our system and therefore reductions of revenue and cash flows.

     Our sources of liquidity include:

• cash generated from operations;

• borrowings under our Credit Facility; and

• future capital market transactions.

     We believe that the cash generated from these sources will be sufficient to meet our current level of quarterly cash distributions of $0.42 per unit and satisfy our short-term working capital and maintenance capital expenditure requirements.  In funding the Alliance Midstream Assets in 2010, we borrowed from our Credit Facility and repaid $11 million upon the underwriters’ exercise of their over-allotment option.

     Our cash flows are significantly influenced by Quicksilver’s production in the Fort Worth Basin.  As Quicksilver and others have developed the Fort Worth Basin, we have expanded our gathering and processing facilities to serve the additional volumes produced by such development.

Cash Flows

	Six Months Ended June 30,
	2010			2009
	(In thousands)
Net cash provided by operating activities	$	26,749		$	33,249
Net cash used in investing activities		(115,121	)		(35,780	)
Net cash provided by financing activities		88,182			2,809

     Cash Flows Used in Operating Activities — The decrease in cash flows from operating activities resulted primarily from the timing of payments from Quicksilver and the timing of insurance premiums in 2010.

     Cash Flows Used in Investing Activities — The increase in cash flows used in investing activities resulted from the distribution to Quicksilver of $80.3 million related to the purchase of the Alliance Midstream Assets.  Additionally, for the 2010 period, we spent $34.8 million for gathering assets and processing facilities.

     Cash Flows Provided by Financing Activities — Changes in cash flows provided by financing activities during the 2010 period resulted primarily from the net borrowings under our Credit Facility of $101.4 million compared with the 2009 period net borrowings of $21 million.  This change is largely reflective of our funding of the purchase of the Alliance Midstream Assets for $84.8 million.  In addition, we distributed $5.0 million more to our unitholders during the 2010 period.  In January 2010, the underwriters of our secondary offering exercised their option to purchase an additional 549,200 common units, which generated proceeds of $11.1 million for which there was no comparable 2009 event.

     Information regarding historical and pending cash distributions is included in Note 3 to our condensed consolidated interim financial statements included in Item 1 of Part I of this Quarterly Report.

Capital Expenditures

     The midstream energy business is capital intensive, requiring significant investment for the acquisition or development of new facilities.  We categorize our capital expenditures as either:

• expansion capital expenditures, which are made to construct additional assets, expand and upgrade existing systems, or acquire additional assets; or

• maintenance capital expenditures, which are made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and extend their useful lives, or to maintain existing system volumes and related cash flows.

     We anticipate that we will continue to make capital expenditures to develop our gathering and processing network as Quicksilver continues to expand its development efforts in the Fort Worth Basin.  Consequently, our ability to develop and maintain sources of funds to meet our capital requirements is critical to our ability to meet our growth objectives and to maintain our distribution levels.

     We currently forecast approximately $72 million in capital expenditures for 2010, of which $6.6 million is classified as maintenance capital expenditures.  These amounts exclude the acquisition of the Alliance Midstream Assets of $84.4 million, but include expected post-acquisition capital expenditures on the Alliance System.  The capital forecast includes $39 million for the construction of pipelines and gathering systems and $33 million for plant and compression assets.

     During the six months ended June 30, 2010, we increased gross property, plant and equipment by $37.1 million, including expansion capital expenditures of approximately $33.5 million, $3.3 million in maintenance capital expenditures and $0.3 million in asset retirement cost.

Other Matters

     We regularly review opportunities for both organic growth projects and acquisitions that will enhance our financial performance.  Since we distribute all of our available cash to our unitholders, we will depend on a combination of borrowings under our Credit Facility, operating cash flows and debt or equity offerings to finance any future growth capital expenditures or acquisitions.

Debt

     Credit Facility — At June 30, 2010, we had $227 million outstanding under our $320 million Credit Facility.  The Credit Facility includes an “accordion feature” that permits us to expand our borrowing capacity to $350 million.  The weighted-average interest rate as of June 30, 2010 was 3.5%.

     At June 30, 2010, our credit agreement required us to maintain a ratio of our consolidated trailing 12-month EBITDA (as defined in our credit agreement) to our net interest expense of not less than 2.5 to 1.0; and a ratio of total indebtedness to consolidated trailing 12-month EBITDA of not more than 4.5 to 1.0.

Our credit agreement contains various covenants that limit, among other things, our ability to:

• incur further indebtedness;

• grant liens;

• sell assets; and

• engage in transactions with affiliates.

     We expect the Crestwood Transaction will cause the Credit Facility to terminate and for a new credit facility to be established by Crestwood.

     Subordinated Note — For the 2010 quarter, the debt ratio requirement was not met, which resulted in no principal payment.  Interest expense of $0.6 million was added to the outstanding principal amount. The interest rate at June 30, 2010 was 4.7%.

As part of the Crestwood Transaction, Crestwood will acquire the Subordinated Note to Quicksilver.

23

     For a more complete description of our indebtedness, see Note 7 to the consolidated financial statements in our 2009 Annual Report on Form 10-K.

Contractual Obligations and Commercial Commitments

     There have been no significant changes to our contractual obligations and commercial commitments as disclosed in Item 7 in our 2009 Annual Report on Form 10-K except for the satisfaction of the contractual obligations related to the Alliance Midstream Assets as disclosed in Item 8 in our 2009 Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

     We have no off-balance sheet arrangements within the meaning of Item 303(a)(4) of SEC Regulation S-K.

Recently Issued Accounting Standards

     The information regarding recent accounting pronouncements is included in Note 2 to our condensed consolidated interim financial statements included in Item 1 of Part I of this Quarterly Report.

Critical Accounting Estimates

     Management’s discussion and analysis of financial condition and results of operations are based on our condensed consolidated interim financial statements and related footnotes contained within Item 1 of Part I of this Quarterly Report.  The process of preparing financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses.  Our critical accounting estimates used in the preparation of the consolidated financial statements were discussed in Item 7 in our 2009 Annual Report on Form 10-K.  These critical estimates, for which no significant changes have occurred in the six months ended June 30, 2010, include estimates and assumptions pertaining to:

• depreciation expense for property, plant and equipment;

• asset retirement obligations; and

• equity-based compensation.

     These estimates and assumptions are based upon what we believe is the best information available at the time of the estimates or assumptions.  The estimates and assumptions could change materially as conditions within and beyond our control change.  Accordingly, actual results could differ materially from those estimates.

24

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     We have established policies and procedures for managing risk within our organization, including internal controls.  The level of risk assumed by us is based on our objectives and capacity to manage risk.

Credit Risk

     Our primary credit risk relates to our dependency on Quicksilver for the majority of our natural gas volumes, which causes us to be subject to the risk of nonpayment or late payment by Quicksilver for gathering and processing fees.  Quicksilver’s credit ratings are below investment grade, where we expect them to remain for the foreseeable future.  Accordingly, this risk could be higher than it might be with a more creditworthy customer or with a more diversified group of customers.  Unless and until we significantly diversify our customer base, we expect to continue to be subject to non-diversified risk of nonpayment or late payment of our fees.  Additionally, we perform credit analyses of our customers on a regular basis pursuant to our corporate credit policy.  We have not had any significant losses due to counter-party failures to perform.

Interest Rate Risk

     Although our base interest rates remain low, our leverage ratios directly influence the spreads charged by lenders.  The credit markets could also drive the spreads charged by lenders upward.  As base rates or spreads increase, our financing costs will increase accordingly.  Although this could limit our ability to raise funds in the capital markets, we expect that our competitors would face similar challenges with respect to funding acquisitions and capital projects.  We are exposed to variable interest rate risk as a result of borrowings under our Credit Facility and our subordinated note to Quicksilver.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

     We carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Securities Exchange Act Rule 13a-15.  Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2010, our disclosure controls and procedures were effective to provide reasonable assurance that material information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

     There has been no change in our internal control over financial reporting during the quarter ended June 30, 2010, that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

25

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

     Our operations are subject to a variety of risks and disputes normally incident to our business.  As a result, we may, at any given time, be a defendant in various legal proceedings and litigation arising in the ordinary course of business.  However, we are not currently a party to any material litigation.

Item 1A. Risk Factors

     There have been no material changes in the risk factors from those described in Part I, Item 1A.  “Risk Factors” included in our 2009 Annual Report on Form 10-K with the exception of additional risk factors related to the Crestwood Transaction.  Some of the incremental risks which may be relevant to us include:

Our ability to operate our business effectively may suffer if we do not, quickly and cost effectively, establish our own operating, maintenance, general and administrative and other functions to operate as a company not controlled by Quicksilver or if we are unable to replace the corporate services Quicksilver provides us in a timely manner or on comparable terms.

     Historically, we have relied on certain general and administrative, operating, maintenance, and other resources of Quicksilver to operate our business.  Quicksilver has performed many important corporate functions for our operations pursuant to the services and secondment agreement we have entered into with Quicksilver and which are expected to terminate upon the closing of the Crestwood Transaction.  While Quicksilver will enter into an agreement to provide transitional services to us for up to six months after the closing of the Crestwood Transaction, Quicksilver will not provide those services on an ongoing basis after the expiration or termination of the transitional services agreement.  We will need to enhance certain financial, legal and compliance, administrative, maintenance, information technology and other support systems and processes or to contract with third parties to provide those services.

     Any failure or significant downturn in Quicksilver’s financial, operational or general and administrative policies and systems during the term of the transitional services agreement or in our financial, operational or general and administrative policies and systems after the term of the transitional services agreement could have a material adverse effect on our business, financial condition or results of operations.

     After the expiration or termination of the transitional services agreement with Quicksilver, Crestwood may not be able to provide us with, and we might not be able to otherwise obtain from third parties, service of similar scope and quality which could have a material adverse effect on our business, financial condition or results of operations.

The sale by Quicksilver of its interests in us and our General Partner will trigger change in control provisions in our long term incentive plan, our Credit Facility and certain agreements with Quicksilver.  We may incur additional general and administrative costs as a result of the Crestwood Transaction.

     Costs may be incurred by us in conjunction with the closing of the Crestwood Transaction, such as those related to the triggering of change in control provisions under certain benefit plans, renegotiating our credit facility and other agreements with Quicksilver, and other possible expenses, including increased general and administrative costs.

     Benefit Plans.  At the closing of the Crestwood Transaction, there will be a change in control involving our General Partner, which will result in an acceleration of vesting of our phantom units granted under our long term incentive plan and held by the non-management directors and executive officers of our general partner and by all employees of Quicksilver who perform services for us.  We expect to recognize approximately $4.4 million of unrecognized costs associated with equity-based compensation of KGS phantom units.

     General and Administrative Costs.  We have relied on certain operating, maintenance, general and administrative and other resources of Quicksilver to operate our business.  Costs allocated to us are based on identification of Quicksilver’s resources which directly benefit us and our estimated usage of shared resources and functions.  As a result of the closing of the Crestwood Transaction, and upon completion or termination of the transitional services agreement with Quicksilver, we expect we will be obligated to bear the full burden of general and administrative costs for Crestwood executives.  We cannot presently determine the extent to which we expect general and administrative costs to increase, but any increase may affect our financial results and operations.

26

     Credit Facility. A change of control as contemplated by the Crestwood Transaction, will constitute an event of default under our Credit Facility.  At the closing of the Crestwood Transaction the lenders under our Credit Facility have the right to accelerate all outstanding amounts due and we may be required to repay our Credit Facility.  We expect that a new credit facility will be established by Crestwood, but we cannot assure you that we or Crestwood will be able to enter into a new credit facility on the same terms as our current Credit Facility or at all.  In addition, we cannot assure you that Crestwood will not cause us to incur additional indebtedness under any new credit facility after or in connection with the close of the Crestwood Transaction, which may affect our financial results and operations.

     Other Agreements. A change of control as contemplated by the Crestwood Transaction will cause the omnibus agreement and the services and secondment agreement we have entered into with Quicksilver to terminate.  In addition, certain master services agreements and other contracts to which we are parties contain change of control and/or assignment provisions that may be triggered by the Crestwood Transaction and certain gathering agreements with Quicksilver will need to be amended and/or extended.  We cannot assure you that we will be able to enter into an omnibus agreement and services and secondment agreement with Crestwood on the same terms as the agreements with Quicksilver.  Any amendments or consents required under the master services agreements and other contracts affected by the Crestwood Transaction or under the gathering agreements may require additional costs and resources and we cannot assure you that we will enter into those amendments or consents on favorable terms or at all.

As a result of the closing of the Crestwood Transaction, Crestwood will own 61% of our common units outstanding and control our General Partner, which has sole responsibility for conducting our business and managing our operations.

     As a result of the closing of the Crestwood Transaction, Crestwood will own all of Quicksilver’s interests in KGS, including 61% of our common units outstanding and 100% control of our General Partner.  Although our General Partner has a fiduciary duty to manage us in a manner beneficial to us and our unitholders, after the closing of the Crestwood Transaction, the directors and officers of our General Partner will have a fiduciary duty to manage our General Partner in a manner beneficial to its owner, Crestwood.  Conflicts of interest may arise between Crestwood and its affiliates, including our General Partner after the closing of the Crestwood Transaction, on the one hand, and us, on the other hand.  In resolving these conflicts of interest, our General Partner may favor its own interests and the interests of its affiliates over our interests.  These conflicts include, among others, the following situations:

• neither our partnership agreement nor any other agreement will require Crestwood or its affiliates to pursue a business strategy that favors us;

• our General Partner is allowed to take into account the interests of parties other than us, such as Crestwood, in resolving conflicts of interest;

• our General Partner determines the amount and timing of asset purchases and sales, capital expenditures, borrowings and repayments of debt, issuance of additional partnership securities, and cash reserves, each of which can affect the amount of cash available for distribution;

• our General Partner determines which costs incurred by it and its affiliates are reimbursable by us;

• our partnership agreement does not restrict our General Partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf;

• our General Partner intends to limit its liability regarding our contractual and other obligations; and

• our General Partner controls the enforcement of obligations owed to us by our General Partner and its affiliates.

Crestwood and its affiliates may compete directly with us.

     Crestwood and its affiliates will not be prohibited from owning assets or engaging in businesses that compete directly or independently with us.  Affiliates of Crestwood currently own various midstream assets and conduct midstream business that may potentially compete with us.  In addition, Crestwood or its affiliates may acquire, construct or dispose of any additional midstream or other assets in the future, without any obligation to offer us the opportunity to purchase or construct or dispose of those assets.  We cannot assure you that Crestwood and its affiliates will enter into any agreement with us that will limit their ability to directly compete with us or govern the resolution of any conflicts of interest.
