Item 1.    Business.



We are a Delaware limited liability company formed in 2006 to own and operate natural gas storage assets. We own or contract for
approximately 204.5 billion cubic feet, or Bcf, of total gas storage capacity. Our assets are located in key North American natural gas producing and consuming regions and are connected at
strategic points on the gas transmission network, providing access to multiple end-use markets. Our locations provide us and our customers with substantial liquidity, meaning access to
multiple counterparties for transactions to buy and sell gas. Since our inception in 2006, we have added 60.3 Bcf of new storage capacity through low cost organic expansions, an increase of
approximately 42%, bringing our total working gas capacity to 204.5 Bcf at the end of March 31, 2011. This year alone, we were able to organically add 19 Bcf of working gas capacity at an
average cost of $1.86 Mcf. We are the largest independent owner and operator of natural gas storage assets in North America, based on our analysis of working gas capacity owned by other storage
owners, adjusted according to each such owner's percentage ownership of its respective storage facilities.

Because
the supply of natural gas remains relatively stable over the course of a year compared to the demand for natural gas, which fluctuates seasonally, natural gas storage facilities
are needed to reallocate excess gas supply from periods of low demand to periods of high demand. We capitalize on the imbalance between supply of and demand for natural gas by providing our customers
and ourselves with the ability to store gas for resale or use in a higher value period. Our natural gas storage facilities allow us to offer our customers "multi-cycle" gas contracts, which permit
them to inject and withdraw their natural gas multiple times in one year, providing more flexibility to capture market opportunities. Since our inception, our storage contracts have provided
cyclability rates ranging from 1.0 to 6.0 times per year, with an average of 2.2 times.

Our
common units are listed on the New York Stock Exchange, or the NYSE, under the symbol "NKA." You may find more information about us on our website at http://www.niskapartners.com.
Our headquarters is located in Houston, TX, and our operations center is located in Calgary, Alberta, Canada.

Our Operations



We store natural gas for a broad range of customers, including financial institutions, marketers, pipelines, power generators,
utilities and producers of natural gas. From inception to March 31, 2011, we utilized an average of approximately 84.3% of our operated capacity for storage services provided to third-party
customers, and our third-party storage contracts contributed an average of 63.9% of our total realized revenue.



We provide multi-year, multi-cycle storage services to our customers under LTF contracts. The volume-weighted average life
of our LTF contracts at March 31, 2011 was 2.6 years. Under our LTF contracts our customers are obligated to pay us monthly reservation fees in exchange for the right to inject, store
and withdraw volumes of natural gas on days and for periods selected by them at injection or withdrawal rates up to maximums specified in the contract. The reservation fees are fixed charges owed to
us regardless of the actual amount of storage capacity utilized by customers. When customers utilize the capacity that is reserved under these contracts we also collect variable fees based upon the
actual volumes of natural gas injected or withdrawn. These variable fees are designed to allow us to recover our variable operating costs and make up a small percentage of the total fees we receive
under our LTF contracts.

Under
LTF contracts, the customer has the right, but not the obligation, to store gas in the facility during the term of the contract, up to a specified volume or "inventory capacity."
In addition to the total amount of inventory capacity, LTF contracts specify a customer's daily withdrawal and injection rights which increase or decrease as the customer's inventory changes. The
maximum injection rate that a customer is typically entitled to is highest when that customer's inventory capacity is empty, reducing as that customer's inventory increases. When a customer's
contracted inventory capacity is full, it has no further injection rights. A customer's maximum withdrawal rate is typically highest when its inventory is full, declining incrementally to zero when
the customer's inventory is empty. LTF contracts provide the customer with the flexibility to use all, a portion, or none of its capacity and the freedom to inject or withdraw gas up to its daily
injection or withdrawal rate, but obligate the customer to remove any injected gas by the end of the contract term.

Reservation
fees comprise over 90% of the revenue received from LTF storage customers, and thus represent a steady and predictable baseline cash flow stream. From inception to
March 31, 2011, we utilized an average of approximately 67.6% of our operated capacity for our LTF strategy, and LTF contracts contributed an average of 46.1% of our total realized revenue. Our
LTF contracts generated average revenues, including both reservation and variable fees of $1.03 per Mcf.



We also provide services for customers under STF contracts. STF contracts typically have terms of less than one year. Under an STF
contract, a customer pays a fixed fee to inject a specified quantity of natural gas on a specified date or dates and to store that gas in our storage facilities until withdrawal on a specified future
date or dates. An STF contract differs from an LTF contract in that the customer is obligated to inject and withdraw specified quantities of natural gas on specified dates rather than entitled to
utilize injection and withdrawal capacity at its option. Because STF contracts set forth specified future injection and withdrawal dates, we can enter into offsetting
transactions to lock in incremental fees as spot and future natural gas prices fluctuate prior to that activity date. From inception to March 31, 2011, we utilized an average of approximately
16.7% of our operated capacity for our STF strategy, and STF contracts contributed an average of 17.8% of our total realized revenue. From inception to March 31, 2011, our STF contracts
generated average revenues of $1.61 per Mcf.

---



Table of Contents

An
example of an STF transaction is when a customer contracts with us in April to inject gas at a steady daily rate in July, when gas prices are low, and to withdraw the same quantity at
a steady daily rate in January, when gas prices are higher. This allows the customers to lock in value in April based on the difference between the January and July prices for natural gas and pay us a
fee based on this difference.

Under
STF contracts the customer is obligated to perform the injection and withdrawal activities as specified in the contract, thus enabling us to enter into offsetting transactions to
capture incremental opportunities as spot and future natural gas prices fluctuate prior to the specified withdrawal date. For example, if, after a customer enters into an STF contract to inject gas in
July and to withdraw that gas in January, gas futures prices for January fall below February prices, we might enter into an offsetting STF transaction for the same quantities, with the same or another
customer, to inject in January and withdraw in February for a fee based on the January to February spread. The result in January would be that the second transaction offsets the first transaction
resulting in no net flow obligation on our storage facility during January, and therefore, a fuel savings. By entering into offsetting transactions, we are able to capture additional opportunities as
they are created throughout the year by the volatile gas futures prices.



Our portfolio of third-party customers consists of a strategic mix of customer types, each of which tends to have a storage usage
pattern that is different from those of other customers at the facility. This means that even though the withdrawal or injection capability of a facility may be fully contracted, it will generally not
be fully utilized on any given day. We purchase, store and sell natural gas for our own account in order to utilize, or optimize, storage capacity and injection and withdrawal capacity that is:
(1) not contracted to customers; (2) contracted to customers, but underutilized by them; or (3) available only on a short-term basis. We have a stringent risk policy
that limits, among other things, our exposure to commodity price fluctuations by requiring us to promptly enter into a forward sale contract or other hedging transaction whenever we enter into a
proprietary purchase contract. Therefore, inventory purchases are matched with forward sales or are otherwise economically hedged so that a margin is effectively locked in promptly after we
enter into the purchase. As a result, there are no speculative positions beyond the minimal operational tolerances specified in our risk policy. From inception to March 31, 2011, we utilized an
average of approximately 15.7% of our operated capacity for our proprietary optimization strategy, and proprietary optimization revenue, after deducting cost of goods sold, contributed an average of
36.1% of our total realized revenue. From inception to March 31, 2011, our proprietary optimization business generated average margins of $2.61 per Mcf on a realized basis before mark to market
gains and losses and inventory writedowns.

We
purchase gas for our own account, inject it and subsequently withdraw and sell the gas. The flexibility arising from purchasing and selling gas for our own account allows us to
generate incremental value through our proprietary optimization strategy by capturing spot and intraday opportunities. Unlike STF and LTF storage transactions, proprietary optimization requires us to
fund the carrying cost of the inventory with our own working capital.

Risk
management techniques, adapted to the unique aspects of gas storage, enable us to match the capacity at our facilities with the portfolio of long-term and
short-term contracts and proprietary optimization transactions at those facilities in order to utilize the maximum amount of capacity available. We utilize New York Mercantile
Exchange Inc., or NYMEX, and Intercontinental Exchange, Inc., or ICE, which are regulated exchanges for the purchase and sale of energy products, to hedge our commodity risk with respect
to the pricing of natural gas. This helps us reduce potential credit, delivery and supply risks. Generally these are financial swaps and are settled without the requirement for physical delivery. In
the case of NYMEX futures, we can enter an EFS (exchange for swaps) to avoid the requirement for delivery.

Table of Contents



Our gas storage customers include a broad mix of gas market participants, including financial institutions, producers, marketers, power
generators, pipelines and municipalities. Approximately 99% of the counterparties under our gas storage contracts and proprietary storage optimization transactions either have an investment grade
credit rating, provide us with another form of financial assurance, such as a letter of credit or other collateral, or are governmental entities.

Although
during certain reporting periods a large portion of our gross revenues can be attributed to one or two counterparties, these gross revenues reflect the full commodity value of
natural gas sales
under our optimization strategy and overstate the counterparties' contribution to our net margin (after cost of goods sold) that is more correlated with our net earnings and operating cash flow.

Our
exposure to the volume of business transacted with a natural gas clearing and settlement facility is mitigated by the facility's requirement to post margin deposits to reduce the
risk of default.

Our Assets

Our owned and operated gas storage facilities consist of AECO Hub (comprised of two facilities in Alberta, Canada), our
Wild Goose storage facility in California and our Salt Plains storage facility in Oklahoma. Our gas storage assets are modern, well-maintained, automated facilities with low maintenance
costs, long useful lives and comparatively high injection and withdrawal, or "cycling," capabilities. Our facilities require low amounts of cushion gas, meaning that a relatively small amount of gas
is required to remain inside our facilities in order to maintain a minimum facility pressure supporting the working gas. The size and flexibility of our facilities, together with the application of
advanced skills in reservoir engineering, drilling, geology and geophysics, enable us to support individual high-cycle contracts in excess of the average physical cycling capabilities of
our facilities. In addition to the facilities we own and operate, we also contract for 8.5 Bcf of gas storage capacity on a long-term basis from Natural Gas Pipeline Company of
America LLC, or NGPL, on its pipeline system in the mid-continent at cost-of-service based rates that we believe are currently below market rates. The

AECO Hub, our largest operation, is comprised of two facilities in Alberta, Suffield and Countess, which are 75 miles
apart but operate as one hub. Due to its high injection and withdrawal capacity (2.8 Bcf per day and 3.1 Bcf per day, respectively), AECO Hub supports high cycling customer contracts.
AECO Hub is the largest natural gas storage provider in western Canada and the largest independent storage hub in North America, based on our analysis of working gas capacity owned by
other storage owners, adjusted according to each such owner's percentage ownership of its respective storage facilities. Its location on TransCanada Pipeline's Alberta System with direct access to

abundant
western Canadian natural gas supply and pipeline connections to most major U.S. and Canadian natural gas markets provides us and our customers with significant flexibility and liquidity.

AECO
Hub is located in the Western Canadian Sedimentary Basin, or the WCSB, which is the major hydrocarbon basin in Canada and one of the most important gas producing
regions in North America. The WCSB accounts for more than 98% of annual Canadian natural gas production and approximately 18% of annual North American natural gas production according to the Canadian
National Energy Board, or NEB. Although WCSB production has leveled off in recent years, we expect that Canadian natural gas production will be sustained in future years by new production from large
new shale plays in northeast British Columbia, a large remaining conventional natural gas resource base, and eventually Arctic gas from the Mackenzie Delta and Alaska.

AECO
Hub is connected to the extensive Alberta System. Most of the gas produced in Alberta flows into the Alberta System, which transports that gas from the well or gas
plant to industrial consumers and gas utilities in Alberta and to export pipelines at the Alberta border. Approximately 10.0 Bcf of gas is delivered into the Alberta System each day, and that volume
is traded many times over by the gas marketing community. As a result, significant liquidity is available to customers of the AECO Hub.

AECO
Hub has been a central part of the Alberta System since the early 1990s, when the Suffield facility began providing title transfers as a hub service before that service
was available on the pipeline. Many transactions were being transacted by storage customers and others at the Suffield facility and a new price index, known as the "AECO Hub Price Index,"
was developed to facilitate price discovery. AECO Hub is the most commonly referenced pricing point for Canadian natural gas, and the price of gas in Alberta is often referred to as the
"AECO Price."



AECO Suffield and AECO Countess, the two facilities that make up the AECO Hub, are geographically separated, but the toll
design of the Alberta System means that they are both commercially located at the same point. This enables us to operate the two facilities as one integrated commercial operation without customers
incurring incremental transportation costs. Customers nominate injections or withdrawals at Suffield's interconnect with the Alberta System, and AECO Hub allocates the nominations between
its Suffield and Countess facilities based on its reservoir management strategy.

Our
rights to use the reservoirs at Suffield and Countess are held pursuant to a series of natural gas storage agreements, trust arrangements and similar instruments entered into with
the holders of subsurface mineral interests of the land where the reservoirs are situated. Rights to access, occupy and use the lands for facilities including the well sites and pipelines are derived
from access agreements, right-of-ways, easements, leases and other similar land use agreements with the surface owners of such land.

Suffield Storage Facility.AECO Suffield is located in southeastern Alberta. It is near the Alberta System's "eastern gate," the
largest natural gas
delivery point in Canada, where gas is delivered into TransCanada's mainline pipeline system (transporting gas to eastern Canada and the northeastern U.S.) and the Foothills/Northern Border pipeline
system (transporting gas to Chicago and the Midwestern U.S.). AECO Suffield consists of 60 storage wells and five storage reservoirs with aggregate effective working capacity of approximately 80.0
Bcf. The storage reservoirs are connected to a central processing and compression facility by a system of five pipelines. Compression is provided by natural gas powered engines that have a total of
more than 36,000 horsepower.

All of the processing and compression facilities and substantially all of the well sites for the storage reservoirs are located on the Canadian Forces Base,
Suffield military training range, or CFB Suffield. CFB Suffield is open prairie land, which provides relatively low costs for seismic surveys, drilling and pipelining. While the military restricts
access to the well sites on a limited basis from time-to-time (i.e., during military exercises), AECO Suffield has not experienced any operational issues due to the
location since its inception in 1988.

Countess Storage Facility.AECO Countess is located in south central Alberta, approximately 60 miles east of Calgary. Countess is
connected to a
large diameter pipe of the Alberta System. This modern gas storage project consists of 29 storage wells and two high performance gas storage reservoirs that are connected to a central processing and
compression facility. The two storage reservoirs each have their own gathering pipeline system. Compression is electrically powered and totals approximately 34,500 horsepower. The two reservoirs have
total effective working capacity of approximately 68.0 Bcf.



AECO Hub's customers consist of a mix of gas market participants, including financial institutions, producers, marketers,
power generators, pipelines and municipalities, resulting in a portfolio of customers with diverse usage patterns and varying contract expiration dates. This allows more opportunity for AECO
Hub to optimize underutilized capacity. Many of our customers actively buy and sell natural gas at key hubs across North America. Our strong relationships at AECO Hub often
result in new business at Wild Goose and Salt Plains.

Most
LTF transactions at AECO Hub are for a gas storage capacity of 1.0 Bcf or greater and average 3.3 Bcf. LTF contract terms have been chosen so that a manageable amount
of contracts expire each year, avoiding exposure to a large contract turnover volume during a temporary market downturn. Existing commitments represent approximately 51% of AECO Hub's
capacity for the fiscal year ending March 31, 2012. The weighted average contract life of our LTF storage contracts at AECO Hub is 2.9 years but most of our current
customers have consistently entered into new contracts when their existing contracts expire. The largest contract we have at AECO Hub is in the seventh year of an initial term of
10 years, with the potential to be extended in five year increments to a maximum term of 25 years under certain circumstances. Upon the expiration of the initial term and each subsequent
five year extension, this contract is automatically extended for five additional years unless either party exercises its right to terminate the contract. Under the contract terms, the party exercising
its early termination rights is subject to the payment of an early termination fee.



Since our inception, we have increased the AECO Hub's gas storage capacity by 39.0 Bcf. We are continuing our delta
pressuring activities at AECO Countess. We expect that the delta pressuring will increase the gas storage capacity of AECO Hub by another 2 Bcf by March 31, 2012.



AECO Hub is subject to provincial regulatory jurisdiction. Operations are subject to the regulation of the Alberta Energy
Resources Conservation Board, or the Alberta ERCB, which must also approve proposed expansions of storage capacity. AECO
Hub is not subject to active market regulation. There is no cost-of-service or other utility-type regulation of storage rates or other commercial terms
of storage contracts in Alberta. While the Alberta Utilities Commission, or the AUC, does have overriding jurisdiction to set gas storage prices when authorized to do so by the Alberta Government, it
is not currently Alberta Government policy to apply such rate regulation. As such, AECO Hub can charge customers negotiated market-based rates as well as store purchased gas for its own
account.

Both AECO Hub facilities are subject to federal and provincial environmental laws and regulations, including oversight by
Alberta's Department of Environment and the Alberta ERCB. There are currently no material environmental issues.



Our Wild Goose storage facility is located 55 miles north of Sacramento, California. Wild Goose is a high deliverability, multi-cycle,
or HDMC storage facility. This HDMC capability is made possible by the rock quality of the Wild Goose reservoirs and the extensive use of horizontal well technology.

Wild
Goose is strategically located in a highly-liquid hub market and is one of only three independent operating storage facilities in northern California. Wild Goose provides natural
gas receipt and delivery services at Pacific Gas & Electric Company, or PG&E Citygate, a liquid trading point where gas supply
from multiple upstream basins meets the volatile California end-use gas demands that create a dependence on natural gas storage. This location provides customers with the opportunity to
take advantage of PG&E Citygate pricing, liquidity and arbitrage opportunities. Wild Goose is connected to two PG&E interconnect pointsLine 167 (a local transmission line), which is
situated adjacent to the facility, and PG&E's Line 400/401 (the large diameter backbone pipelines) via our own 25 mile, 30 inch connector pipeline. Wild Goose benefits from the energy supply and
demand dynamics of California, including underlying natural gas consumption growth, fluctuating gas-fired power generation demand, a dual-peaking market for gas prices,
uncertainty of pipeline supply and the potential for significant new power generation demand (partly due to the varying availability of hydro-power) to back up renewable energy sources such as wind
and solar. These dynamics support high demand for natural gas storage.



Wild Goose operates 15 gas storage wells that are completed in three depleted natural gas reservoirs with an effective working capacity
of 35.0 Bcf and a gas generated compression of 20,800 horsepower. The Wild Goose reservoirs are located in high quality rock formations. In addition, the reservoirs have a strong water drive
mechanism, which helps maintain reservoir pressure and well deliverability. Rights to use the reservoirs at Wild Goose for natural gas storage are held pursuant to a series of natural gas storage
leases with the surface owners of the lands where the reservoirs are situated as well as mineral owner agreements and similar instruments entered into with the holders of subsurface mineral interests
in such lands. Rights for the lands used for the pipelines are derived from right-of-ways, easements, leases, and other similar land-use agreements.



Wild Goose's customers include a mix of gas market participants, including financial institutions, producers, marketers, power
generators, pipelines and municipalities, resulting in a portfolio of customers with diverse usage patterns and different contract expiration dates. This allows us to optimize underutilized capacity.

Wild
Goose has contracts with over a dozen third-party customers for terms of one year or longer. Existing commitments represent approximately 74% of Wild Goose's capacity for the fiscal
year ending March 31, 2012. The weighted average contract life of our LTF storage contracts at Wild Goose is 1.9 years, but many of our current customers have consistently entered into
new contracts when their existing contracts expire.

Since our inception, we have increased the gas storage capacity of Wild Goose by 17.0 Bcf. In December 2010 we received approval from
the California Public Utilities Commission, or CPUC to amend Wild Goose's certificate to further expand the facility to 50.0 Bcf of gas storage capacity and to increase its maximum injection rate from
450 to 650 MMcf per day and its maximum withdrawal rate from 700 to 1,200 MMcf per day. This approval allowed us to quickly increase Wild Goose's gas storage capacity to 35.0 Bcf. In addition, we
commenced construction activities to increase the capacity further to 50.0 Bcf as soon as is practicable. We expect that the remaining 15.0 Bcf of certificated capacity will be available for service
no later than March 31, 2012.



Wild Goose is regulated as a state utility by the CPUC and is certified to serve the California intra-state market. Wild Goose has
regulatory authority to negotiate market based rates for third-party storage contracts and buys and sells gas for its own account to optimize its operations. In addition, as an independent storage
provider Wild Goose is exempt from the provisions of California's affiliate conduct rules and has the right to coordinate its operation with our other facilities. It is however, restricted from
contracting for natural gas storage services with its affiliates.



There are currently no material environmental liabilities at Wild Goose. Wild Goose operates in environmentally sensitive agricultural
and wetlands recreation environments. All facilities are modern and are operated based on strict environmental and maintenance standards.

In
constructing and expanding the Wild Goose facility, we have experienced no significant environmental-related delays or unexpected costs, by initially bringing forward development
plans that
mitigate any environmental impacts to the satisfaction of all responsible agencies and stakeholders. Wild Goose has received the State of CaliforniaDepartment of Conservation Award for
Outstanding Oilfield Lease and Facility Maintenance for six consecutive years.



Our Salt Plains storage facility is located 110 miles north of Oklahoma City, Oklahoma, in a region of growing demand for natural gas
as a fuel for heating and power generation. Salt Plains provides intrastate services in Oklahoma through its connection to pipelines operated by ONEOK Gas Transportation Pipelines, L.L.C., or ONEOK,
and intrastate and interstate services through its interconnect with pipelines operated by Southern Star Central Gas Pipeline, Inc., or Southern Star. The heightened supply and demand
imbalances in this market create increased margin opportunities for us and our customers.

Salt
Plains is in a strategic mid-continent location with interconnects to pipelines owned by Southern Star and ONEOK, which serve both regional and mid-continent
gas markets. This provides customers the benefits of liquidity, supply, and arbitrage opportunities. In addition, gas produced in the Rocky Mountains that is delivered to the mid-continent
region gets redistributed to various pipelines such as Southern Star that have access to Salt Plains. Growing shale gas development in neighboring regions, such as the Barnett, Fayetteville,
Haynesville and Cana Woodford shales, is also adding significant supply to the mid-continent region, which has the potential to increase demand for gas storage services. Compression is
gas-powered and totals approximately 10,000 horsepower. The reservoir has a total working gas storage capacity of approximately 13.0 Bcf.

Table of Contents



Salt Plains operates 30 wells that are completed in a depleted natural gas storage reservoir characterized by high-quality
rock. The wells are connected to a central plant facility by seven miles of pipeline. Rights to use the reservoir at Salt Plains for natural gas storage are held pursuant to a series of gas storage
agreements with the mineral rights owners of the lands where the reservoir is situated. Rights for the lands used for the pipelines are derived under these gas storage agreements as well as from
right-of-way grants from other land owners.



Existing commitments represent approximately 36% of Salt Plains' capacity for the 2012 fiscal year. The weighted average contract life
of our LTF storage contracts at Salt Plains is 1.4 years, but most of our current customers have consistently entered into new contracts when their existing contracts expire. The largest
contract we have at Salt Plains is in the third year of a three year term.



Since our inception, we have increased the facility's gas storage capacity by 4.3 Bcf. We believe there is the potential for
opportunities to expand the gas storage capacity of the facility and we are currently assessing the feasibility of such expansion in the future.



Our Salt Plains intrastate operations are subject to regulation by the Oklahoma Corporation Commission, or the OCC. Salt Plains is also
authorized to provide interstate storage service under the Natural Gas Policy Act of 1978 and the Federal Energy Regulatory Commission, or FERC, regulations and policies that allow intrastate pipeline
and storage companies to engage in interstate commerce (commonly known as NGPA section 311 services). Salt Plains provides these NGPA section 311 services, which are not subject to
FERC's broader jurisdiction under the
Natural Gas Act, pursuant to a Statement of Operating Conditions which is on file with FERC. The OCC's regulatory policies are generally less stringent than those of FERC. Currently, Salt Plains is
authorized to charge market based rates in both intrastate and interstate service and has no restrictions on affiliate interactions.



We are not aware of any current material environmental liabilities relating to the Salt Plains facility.



Since 2001, our subsidiary has contracted for 8.5 Bcf of gas storage capacity on the MidCon leg and the TexOk leg of the NGPL pipeline
system in the mid-continent. The NGPL system connects and balances Gulf Coast and mid-continent supply basins with Chicago and other Midwestern U.S. end-use
markets. NGPL has a number of different storage facilities on its pipeline system and manages its storage capacity as pools on separate legs of the pipeline. Under NGPL's
FERC-approved tariff, NGPL is limited to charging cost-of-service rates for its transportation and storage services. We currently have multiple LTF storage
contracts with NGPL that expire on various dates through 2017. We have a tariff-based right of first refusal to renew these contracts at NGPL's favorable
cost-of-service rate, effectively making this capacity a long-term asset without any invested capital, with an option to exit should the rate be above market value.

As
a customer of the NGPL capacity, and not the operator, Niska uses its optimization strategy to generate revenue from its use of the capacity, and does not remarket services.



We have a small but growing gas marketing business in Eastern Canada, British Columbia and Alberta serving commercial, industrial and
retail customers. This is also a margin business where supply is locked in to serve customers at committed prices. In Eastern Canada, EnerStream Agency Services also provides fee based agency services
to natural gas end-users.

Regulation

Our operations are subject to extensive laws and regulations that have the potential to have a significant impact on our business. We
may incur substantial costs in order to conduct our operations in compliance with these laws and regulations. We are subject to regulatory oversight by federal, state, provincial and local regulatory
agencies, many of which implement rules and regulations that are binding on the natural gas storage and pipeline industry, related businesses and individual participants. The failure to comply with
such laws and regulations can result in substantial penalties. The cost of regulatory compliance on our operations increases our costs of doing business and, consequently, affects our profitability.
However, we do not believe that we are affected in a significantly different manner by these laws and regulations than are our competitors.

Our
historical and projected operating costs reflect the recurring costs resulting from compliance with these regulations, and we do not anticipate material expenditures in excess of
these amounts in the absence of future acquisitions or changes in regulation, or discovery of existing but unknown compliance issues. The following is a summary of the kinds of regulation that may
impact our operations. However, such discussion should not be considered an exhaustive review of all regulatory considerations affecting our operations.



Our natural gas storage operations are subject to stringent and complex federal, state, provincial and local laws and regulations
governing environmental protection, including air emissions, water quality, wastewater discharges, and solid waste management. Such laws and regulations generally require us to obtain and comply with
a wide variety of environmental registrations, licenses, permits and other approvals. These laws and regulations impose numerous obligations that are applicable to our operations, including the
acquisition of permits to conduct certain activities under statutes such as the Clean Water Act, or CWA, the Clean Air Act, or CAA, the Safe Drinking Water Act, or SDWA and comparable legislation in
Canada limiting or preventing the release of materials from our facilities, managing wastes generated by our operations, the installation of pollution control equipment, responding to releases of
process materials or wastes from our operations, and the risk of substantial liabilities for pollution resulting from our operations. The Occupational Safety and Health Act, or OSHA, comparable state
statutes that regulate the protection of the health and safety of workers, as well as the Occupational Health and Safety Act in the Province of Alberta, and comparable federal legislation in Canada
also apply to our operations. Failure to comply with these laws and regulations may trigger a variety of administrative, civil, and criminal enforcement measures, including the assessment of monetary
penalties, the imposition of remedial obligations and the issuance of injunctions limiting or preventing some or all of our operations. We believe that we are in substantial compliance with existing
environmental laws and regulations and that such laws and regulations will not have a material adverse effect on our business, financial position or results of operations. Nevertheless, the trend in
environmental regulation is to place more restrictions and limitations on activities that may affect the environment. As a result, there can be no assurance of the amount or timing of future

11

Table of Contents

expenditures
for environmental compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate.



The workplaces in the U.S. associated with the storage facilities we operate are subject to the requirements of the Federal
Occupational Safety and Health Act, or OSHA, as amended, as well as comparable state statutes that regulate the protection of the health and safety of workers. Workplaces in Canada associated with our
operations are subject to the requirements of the Occupational Health and Safety Act in the Province of Alberta and comparable federal legislation. Failure to comply with OSHA requirements, or
comparable requirements in Canada, including general industry standards, recordkeeping requirements and monitoring of occupational exposure to regulated substances, could subject us to fines or
significant compliance costs.



There is increasing attention in the United States and worldwide concerning the issue of climate change and the effect of greenhouse
gases (GHGs). Future regulation of GHGs in the United States could occur pursuant to future U.S. treaty commitments, new domestic legislation that may impose a carbon emissions tax or establish a
cap-and-trade program or regulation by the EPA. The Obama Administration has indicated its support for a mandatory cap and trade program to reduce GHG emissions. However, a
change in the control of Congress makes it unlikely that federal climate change legislation will be passed in the next few years. Similarly, the outcomes of the ongoing international negotiations
since Cancun make it unlikely that a new, legally-binding international instrument to control GHGs will be adopted in the near future.

While
a new federal or international program seems unlikely, we may have to comply with state or regional programs to limit GHG emissions. State and regional programs that may impact our
operations include the Western Climate Initiative (WCI) and the Regional Greenhouse Gas Initiative (RGGI). Given New Jersey's recent withdrawal, the future status of RGGI, and agreement between the
states in the Northeastern U.S. is uncertain. We do not believe that RGGI will impact our business because we do not currently have operations in RGGI member states. The WCI is an agreement between
the states of California, Oregon, Washington, New Mexico, Arizona, Utah and Montana, and the Canadian provinces of British Columbia, Manitoba, Ontario, and Quebec. If enough WCI member states pass
implementing legislation, the WCI will create a regional cap-and-trade scheme for GHG emissions. Depending on the scope of any regional programs that we must comply with, we
could be required to obtain and surrender allowances for GHG emissions statutorily attributed to our operations (e.g., emissions from compressor stations or the injection and withdrawal of
natural gas). Although we would not be impacted to any greater degree than other similarly situated natural gas storage companies, a stringent GHG control program could have an adverse effect on our
cost of doing business and reduce demand for the natural gas storage services we provide.

In
2006, the California State Legislature passed and Governor Schwarzenegger signed AB 32, the Global Warming Solutions Act of 2006, with a goal of reaching (i) 1990 GHG emissions
levels by the year 2020, (ii) 80% of 1990 levels by 2050, and (iii) establishing mandatory emissions reporting program. AB 32 directed the California Air Resources Board, or CARB, to
begin developing discrete early actions to reduce GHGs while also preparing a scoping plan to identify how best to reach the 2020 limit. Since the passage of AB 32, the CARB approved in December 2010
a GHG cap-and-trade program, which is scheduled to take effect in 2012. However, a recent court order and citizens' challenge threatens to delay California's
cap-and-trade program. No final determination has been made with regard to the potential applicability of the AB 32 cap-and-trade program to our
operations. We are therefore not in a position to quantify any potential costs associated with compliance under the program as proposed. However, any limitation a finalized program places on GHG
emissions from our

12

equipment
and operations could require us to incur costs to reduce the GHG emissions associated with our operations.

Even
in the absence of new federal legislation the U.S. Environmental Protection Agency, or EPA, has begun to regulate GHG emissions pursuant to the federal Clean Air Act (CAA) based on
the April 2007 United States Supreme Court ruling inMassachusetts, et al. v. EPAthat the EPA has authority to regulate carbon dioxide emissions. The
GHG regulations that EPA has issued following exercising the authority affirmed byMassachusetts v. EPAinclude: (1) the December 2009
"endangerment finding" determining that air pollution from six GHGs endangers public health and welfare, and that mobile sources cause or contribute to that air pollution; (2) the May 2010
"Tailpipe Rule," issued jointly with the National Highway Traffic Safety Administration setting GHG emission and fuel economy standards for new light-duty vehicles; (3) the April
2010 "Timing Rule," concluding that stationary source regulation under Titles I and V of the CAA (involving Prevention of Significant Deterioration regulations and operating permits, respectively)
must regulate GHG emissions beginning when such emissions are subject to controls under the mobile source provisions of the Act; (4) the June 2010 "Tailoring Rule," temporarily exempting small
stationary sources from PSD and Title V requirements through regulations modifying the Act's emissions thresholds; and (5) the December 2010 "SIP Call" rule, finding 13 State Implementation
Plans ("SIPs") inadequate because they did not regulate GHGs from stationary sources, and directing those States to correct the inadequacies or face federalization of their permitting programs. The
first four rules have been challenged in consolidated litigation in the D.C. Circuit. However, the Court refused to stay the rules while the challenge is pending.

In
addition to the above rules, the EPA has stated that it intends to propose standards for power plants in July 2011 and for refineries in December 2011 and will issue final standards
in May 2012 and November 2012, respectively. Finally, in December 2010, the EPA issued its plan to update pollution standards for fossil fuel power plants and petroleum refineries. This new standard
along with the current EPA's GHG regulations could affect the demand for gas.

Pursuant
to a Congressional mandate in the FY2008 Consolidated Appropriations Act, EPA has promulgated regulations requiring the measuring and reporting of GHG emissions from a variety
of
industrial sources. Finalized in October 2009, the Mandatory Reporting of Greenhouse Gas Emissions Rule (Mandatory Reporting Rule or MRR) sets out general provisions applicable to all entities with
MRR compliance obligations, as well as a series of subparts covering particular industrial sectors. For most sectors, MRR obligations are triggered when the facility's emissions exceed 25,000 metric
tons of carbon dioxide equivalent in a year, however, some facilities will be covered regardless of their emissions levels. Since the initial MRR was finalized, the EPA has gone on to finalize
additional subparts, bringing new sectors within the scope of the rule. Finalized in June 2010, Subpart W of the MRR applies to owners and operators of petroleum and natural gas systems, which
are defined to include onshore oil and natural gas production, offshore oil and natural gas production, onshore natural gas process, onshore natural gas transmission and compression, underground
natural gas storage, LNG storage, and LNG import and export activities be subject to the MRR's requirements if they emit more than 25,000 metric tons of carbon dioxide equivalent per year. Because our
primary business involves underground natural gas storage, we are potentially subject to Subpart W of the MRR.

Canada
is a signatory to the United Nations Framework Convention on Climate Change and has ratified the Kyoto Protocol established thereunder to set legally binding targets to reduce
nation-wide emissions of carbon dioxide, methane, nitrous oxide, and other GHG. It is generally anticipated that the Canadian government will consider regulatory measures similar to those
being proposed by the EPA, but new national legislation on climate change is not expected at this time. Rather, the majority of GHG initiatives in Canada are likely to be in the form of regional
initiatives.

British
Columbia has been in the process of implementing a cap-and-trade system consistent with the requirements of the WCI. The province has created a Climate
Action Secretariat that is responsible for developing cap-and-trade rules. Ontario, another province participating in the WCI, has committed to a phase out of
coal-fired power by 2014.

Alberta
regulates GHG emissions under the Climate Change and Emissions Management Act, the Specified Gas Reporting Regulation (the "SGRR"), which imposes GHG emissions reporting
requirements, and the Specified Gas Emitters Regulation (the "SGER"), which imposes GHG emissions limits. A facility subject to the SGRR must report if it has GHG emissions of 50,000 metric tonnes or
more from a facility in any year. Under the SGER, GHG emission limits apply once a facility has direct GHG emissions in a year of 100,000 metric ton or more. Under the SGER, subject facilities are
required to reduce their emission intensities (e.g., metric ton of GHGs emitted per unit of production) by 12% in the case of facilities operating prior to 2000 and by 2% per year beginning in
the fourth year of commercial operations for facilities commencing operations in 2000 and after up to a maximum of 12%. A facility subject to the SGER may meet the applicable emission limits by making
emissions intensity improvements, offsetting GHG emissions by purchasing offset credits or emission performance credits in the open market, or acquiring "fund credits" by making payments of CDN$15 per
metric tonne to the Alberta Climate Change and Management Fund. The direct and indirect costs of these regulations may adversely affect our operations and financial results.

Rates

Commercial arrangements at our facilities in the U.S. are subject to the jurisdiction of regulators, including FERC, the OCC and the
CPUC. With authorization of the Alberta Government, commercial arrangements at our facility in Alberta, Canada, could be regulated by the AUC, but it is not currently Alberta Government policy to
apply any such rate regulation. Each of our facilities currently has the ability to negotiate and charge rates based upon market prices, and are not limited to charging
cost-of-service rates which are capped at recovery of costs plus a reasonable rate of return. The exemptions we receive under the regulatory regimes applicable to us enable us
to buy, sell and store natural gas for our own account at our existing storage assets. The ability to charge market-based rates enables us to charge greater prices than many other storage providers
which are required to charge cost-of-service based rates and our ability to buy, sell and store natural gas for our own account enables us to optimize our working gas capacity.
In addition, we are permitted to consolidate management, marketing, and administrative functions for efficiencies in matters that some competing operators are prohibited from due to affiliate rules to
which they are subject.

Employees

As of March 31, 2011, we had 129 employees. Our executive officers are currently employed by Niska Partners
Management ULC and subsidiaries of Niska Gas Storage Partners LLC.

Competition

The natural gas storage business is competitive. The principal elements of competition among storage facilities are rates, terms of
service, types of service, access to supply sources, access to demand markets and flexibility and reliability of service. Because our facilities are strategically located in key North American natural
gas producing and consuming regions, we face competition from existing competitors who also operate in those markets. Our competitors include gas storage companies, major integrated energy companies,
pipeline operators and natural gas marketers of varying sizes, financial resources and experience. Competitors of the AECO Hub currently include TransCanada (Edson, CrossAlta), Atco
(Carbon) and Enstor (Alberta Hub). Competitors of our Wild Goose facility currently include Buckeye Partners (Lodi), PG&E, NW Natural and PG&E (Gill Ranch) and a number of proposed projects in
northern California. Competitors of our Salt Plains facility currently include Southern Star. Given the key location of our facilities, additional competition in the markets we serve could arise from
new developments or expanded operations from existing competitors. We anticipate that growing demand for natural gas storage in the markets we serve will be met with increasing storage capacity,
either through the expansion of existing facilities or the construction of new storage facilities.

Seasonality

Our cash expenditures related to our optimization activities are highest during summer months, and our cash receipts from our
optimization activities are highest during winter months. Consequently, our results of operations for the summer are generally lower than for the winter. With lower cash flow during the second and
third calendar quarters, we may be required to borrow money in order to pay distributions to our members.

Item 1A.    Risk Factors.

In addition to the factors discussed elsewhere in this report, including the financial statements and related
notes, you should consider carefully the risks and uncertainties described below, which could materially adversely affect our business, financial condition and results of operations. If any of these
risks or uncertainties were to occur, our business, financial condition or results of operation could be adversely affected.

Risks Inherent in Our Business

We may not have sufficient cash following the establishment of cash reserves and payment of fees and expenses to enable us to make cash distributions to holders of our
common units at the minimum quarterly distribution rate under our cash distribution policy.

We may not have sufficient cash each quarter to pay the full amount of our minimum quarterly distribution of $0.35 per unit, or $1.40
per unit per year, which will require cash of approximately $24.1 million per quarter, or $96.6 million per year, based on the number of common and subordinated units currently
outstanding. Under our cash distribution policy, the amount of cash we can distribute on our units principally depends upon the amount of cash generated from our operations, which will fluctuate based
on, among other things:



15

Table of Contents



In
addition, the actual amount of cash we will have available for distribution will depend on other factors, including:



For
a description of additional restrictions and factors that may affect our ability to pay cash distributions, see "Management's Discussion of Financial Condition and Results of
OperationsLiquidity and Capital Resources."

The amount of cash we have available for distribution to holders of our units depends primarily on our cash flow and not solely on profitability, which may prevent us from
making cash distributions during periods when we record net earnings.

The amount of cash we have available for distribution depends primarily upon our cash flow, including cash flow from reserves and
working capital or other borrowings, and not solely on profitability, which will be affected by non-cash items. As a result, we may pay cash distributions during periods when we record net
losses for financial accounting purposes and may not pay cash distributions during periods when we record net earnings.

Our level of exposure to the market value of natural gas storage services could adversely affect our revenues and cash available to make distributions.

As portions of our third-party gas storage contract portfolio come up for replacement or renewal, and capacity becomes available,
adverse market conditions may prevent us from replacing or renewing the contracts on terms favorable to us. The market value of our storage capacity, realized through the value customers are willing
to pay for LTF contracts or via the opportunities to be captured by our STF contracts or optimization activities, could be adversely affected by a number of factors beyond our control,
including:



16

---



Table of Contents



From
our inception in May 2006 to March 31, 2011, we utilized an average of approximately 67.6% of our operated capacity for our LTF strategy, representing an average of
approximately 46.1% of annual realized revenue. The volume-weighted average life of our LTF contracts at March 31, 2011 was 2.6 years. From inception to March 31, 2011, we
utilized an average of approximately 16.7% of our operated capacity for our STF strategy, representing an average of approximately 17.8% of annual realized revenue. Over the same period, we utilized
an average of approximately 15.7% of our operated capacity for our proprietary optimization strategy, representing an average of approximately 36.1% of annual revenue. As of March 31, 2011,
approximately 22% of our LTF contracts and all of our STF contracts were due to expire on or before March 31, 2012. A prolonged downturn in the natural gas storage market due to the occurrence
of any of the above factors could result in our inability to renegotiate or replace a number of our LTF contracts upon their expiration, leaving more capacity exposed to the value that could be
generated through STF contracts or optimization. STF and optimization values would be impacted by the same factors, and market conditions could deteriorate further before the opportunity to extract
value with those strategies could be realized.

Further,
our lines of business and assets are concentrated solely in the natural gas storage industry. Thus, adverse developments, including any of the industry-specific factors listed
above, would have a more severe impact on our business, financial condition, results of operations and ability to pay distributions than if we maintained a more diverse business.

We face significant competition that may cause us to lose market share, negatively affecting our business.

Our ability to renew or replace existing contracts with our customers at rates sufficient to maintain current revenue and cash flows
could be adversely affected by the activities of our competitors. The natural gas storage business is highly competitive. The principal elements of
competition among storage facilities are rates, terms of service, types of service, deliverability, supply and market access, flexibility and reliability of service. Our operations compete primarily
with other storage facilities in the same markets in the storage of natural gas. The CPUC has adopted policies that favor the development of new storage projects and there are numerous projects,
including expansions of existing facilities and greenfield construction projects, at various stages of development in the market where our Wild Goose facility operates. These projects, if developed
and placed into service, may compete with our storage operations.

We
also compete with certain pipelines, marketers and liquefied natural gas, or LNG, facilities that provide services that can substitute for certain of the storage services we offer. In
addition, natural gas as a fuel competes with other forms of energy available to end-users, including electricity, coal and liquid fuels. Increased demand for such forms of energy at the
expense of natural gas could lead to a reduction in demand for natural gas storage services. Some of our competitors have greater financial resources and may now, or in the future, have greater access
to expansion or development opportunities than we do.

If
our competitors substantially increase the resources they devote to the development and marketing of competitive services or substantially decrease the prices at which they offer
their services, we may be unable to compete effectively. Some of these competitors may expand or construct new storage facilities that would create additional competition for us. The storage facility
expansion and

Table of Contents

construction
activities of our competitors could result in storage capacity in excess of actual demand, which could reduce the demand for our services, and potentially reduce the rates that we receive
for our services.

We
also face competition from alternatives to natural gas storageways to increase supply of or reduce demand for natural gas at peak times such that storage is less
necessary. For example, excess production or supply capability with sufficient delivery capacity on standby until required for peak demand periods or ability for significant demand to quickly switch
to alternative fuels at peak times would represent alternatives to gas storage.

Competition
could intensify the negative impact of factors that significantly decrease demand for natural gas at peak times in the markets served by our storage facilities, such as
competing or alternative forms of energy, a recession or other adverse economic conditions, weather, higher fuel costs and taxes or governmental or regulatory actions that directly or indirectly
increase the cost or limit the use of natural gas. Increased competition could reduce the volumes of natural gas stored in our facilities or could force us to lower our storage rates.

If third-party pipelines interconnected to our facilities become unavailable or more costly to transport natural gas, our business could be adversely affected.

We depend upon third-party pipelines that provide delivery options to and from our storage facilities for our benefit and the benefit
of our customers. Because we do not own these pipelines, their continuing operation is not within our control. These pipelines may become unavailable for a number of reasons, including testing,
maintenance, line repair, reduced operating pressure, lack of operating capacity or curtailments of receipt or deliveries due to insufficient capacity. In addition, these third-party pipelines may
become unavailable to us and our customers because of the failure of the interconnects that transport gas between our facilities and the third-party pipelines. Because of the limited number of
interconnects at our facilities (Wild Goose is connected to third-party pipelines by two interconnects, AECO Hub by two interconnects (one at each facility) and Salt Plains by two
interconnects), the failure of any interconnect could materially impact our ability or the ability of our customers to deliver gas into the third-party pipelines. If the costs to us or our storage
service customers to access and transport on these third-party pipelines significantly increase, our profitability could be reduced. If third-party pipelines become partially or completely
unavailable, our ability to operate could be restricted, thereby reducing our profitability. A prolonged or permanent interruption at any key pipeline interconnect could have a material adverse effect
on our business, financial condition, results of operations and ability to pay distributions to our members.

Our operations are subject to operational hazards and unforeseen interruptions, which could have a material adverse effect on our business.

Our operations are subject to the many hazards inherent in the storage of natural gas, including, but not limited
to:

Table of Contents



These
risks could result in substantial losses due to breaches of our contractual commitments, personal injury or loss of life, damage to and destruction of property and equipment and
pollution or other environmental damage and may result in curtailment or suspension of our operations. In addition, operational interruptions or disturbances, mechanical malfunctions, faulty
measurements or other acts, omissions, or errors may result in significant costs or lost revenues. Gas that moves outside of the effective drainage area through migration could be permanently lost and
will need to be replaced to maintain design storage performance.

We are not fully insured against all risks incident to our business, and if an accident or event occurs that is not fully insured it could adversely affect our business.

We may not be able to obtain the levels or types of insurance we desire, and the insurance coverage we do obtain may contain large
deductibles or fail to cover certain hazards or cover all potential losses. The occurrence of any operating risks not covered by insurance could have a material adverse effect on our business,
financial condition, results of operations and ability to pay distributions to our members.

We are exposed to the credit risk of our customers, and any material nonpayment or nonperformance by our key customers could adversely affect our financial results and cash
available for distribution.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers. Our credit procedures and policies may
not be adequate to fully eliminate customer credit risk. If we fail to adequately assess the creditworthiness of existing or future customers or unanticipated deterioration in their creditworthiness,
any resulting increase in nonpayment or nonperformance by them and our inability to re-market or otherwise use the capacity could have a material adverse effect on our business, financial
condition, results of operations and ability to pay distributions to our members.

Our debt levels may limit our flexibility in obtaining additional financing and in pursuing other business opportunities.

Our $800.0 million principal amount of outstanding indebtedness consists of the 8.875% senior notes due 2018 of Niska US and
Niska Canada. Our level of debt could have important consequences to us, including the following:



Our
ability to service our debt will depend upon, among other things, our future financial and operating performance, which will be affected by prevailing economic conditions and
financial, business,

19

Table of Contents

regulatory
and other factors, some of which are beyond our control. In addition, our ability to service our debt under our credit facilities will depend on market interest rates because the interest
rates applicable to our borrowings will fluctuate with movements in interest rate markets. If our operating results are not sufficient to service our current or future indebtedness, we will be forced
to take actions such as reducing or terminating distributions and reducing or delaying our business activities, acquisitions, investments or capital expenditures. In addition, we may take actions such
as selling assets, restructuring or refinancing our debt or seeking additional equity capital although we may not be able to effect any of these actions on satisfactory terms, or at all. Our inability
to obtain additional financing on terms favorable to us or our inability to service our debt could have a material adverse effect on our business, results of operations, financial condition and
ability to pay distributions. See "Management's Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital Resources."

Restrictions in the agreements governing our indebtedness could limit our ability to make distributions to our members.

We will be dependent upon the cash flow generated by our operations in order to meet our debt service obligations and to allow us to
make distributions to our members. The operating and financial restrictions and covenants in our credit agreement, the indenture governing our senior notes and any future financing agreements could
restrict our ability to finance future operations or capital needs or to expand or pursue our business activities, which may, in turn, limit our ability to make distributions to our members. For
example, our credit agreement and the indenture governing our senior notes restrict or limit our ability to:



Furthermore,
our credit agreement contains covenants requiring us to maintain certain financial ratios and tests, including that we maintain a fixed charge coverage ratio of 1.1 to 1.0
at the end of each fiscal quarter when excess availability under both revolving credit facilities is less than 15% of the aggregate amount of availability under both credit facilities. Our ability to
comply with those covenants may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If we violate any of the restrictions, covenants, ratios or
tests in our credit agreement or the indenture governing our senior notes, the lenders or the noteholders, as the case may be, will be able
to accelerate the maturity of all borrowings and demand repayment of amounts outstanding, our lenders' commitment to make further loans to us may terminate, and we may be prohibited from making
distributions to our members. We might not have, or be able to obtain, sufficient funds to make these accelerated payments.

20

Table of Contents

The indenture governing our senior notes prohibits us from making distributions to unitholders if any default or event of default (as defined in the indenture)
exists. In addition, both the indenture and our $400 million credit agreement contain covenants limiting our ability to pay distributions to unitholders. The covenants apply differently
depending on our fixed charge coverage ratio (defined substantively the same in the indenture and the credit agreement). If the fixed charge coverage ratio is greater than 1.75 to 1.0, we will be
permitted to make restricted payments, including distributions to our unitholders, if the aggregate restricted payments since the date of our IPO, excluding certain types of permitted payments, are
less than the sum of a number of items including, most importantly, operating surplus (defined similarly to the definition in our Operating Agreement) calculated as of the end of our preceding fiscal
quarter and the aggregate net cash proceeds received by us as a capital contribution or from the issuance of equity interests, including the net proceeds received from our IPO. The indenture governing
our senior notes contains an additional general basket of $75 million not contained in our credit agreement.

See
"Management's Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital ResourcesOur $400.0 Million Credit
Agreement" and "Our 8.875% Senior Notes Due 2018." Any subsequent replacement of our credit agreement, our senior notes or any new indebtedness could have similar or greater restrictions.

We will be required to make capital expenditures to increase our asset base. If we are unable to obtain needed capital or financing on satisfactory terms, our ability to pay
cash distributions may be diminished or our financial leverage could increase.

In order to increase our asset base, we will need to make expansion capital expenditures. If we do not make sufficient or effective
expansion capital expenditures, we will be unable to expand our business operations and may be unable to raise the level of our cash distributions. To fund our expansion capital expenditures, we will
be required to use cash from our operations or incur borrowings or sell additional common units or other membership interests. Such uses of cash from operations will reduce cash available for
distribution to our members. Our ability to obtain bank financing or to access the capital markets for future equity or debt offerings may be limited by our financial condition at the time of any such
financing or offering and the covenants in our existing debt agreements, as well as by general economic conditions and contingencies and uncertainties that are beyond our control. Even if we are
successful in obtaining the necessary funds, the terms of such financings could limit our ability to pay distributions to our members. In addition, incurring additional debt may significantly increase
our interest expense and financial leverage and issuing additional membership interests may result in significant unitholder dilution and increase the aggregate amount of cash required to maintain the
then-current distribution rate, which could materially decrease our ability to pay distributions at the then-current distribution rate.

If we do not successfully complete expansion projects or make and integrate acquisitions that are accretive, our future growth may be limited.

A principal focus of our strategy is to grow the cash distributions on our units by expanding our business. Our ability to grow depends
on our ability to complete expansion and development projects and make acquisitions that result in an increase in cash per unit generated from operations. We have near term projects in progress to
expand our capacity by up to an additional 17.0 Bcf, including 15.0 Bcf of capacity expected to become available by March 31, 2012 at Wild Goose and an additional 2.0 Bcf of
capacity expected to become available by March 31, 2012 at AECO. We may be unable to successfully complete accretive expansion or development projects or acquisitions for any of the following
reasons:



21

Table of Contents



If
any expansion or development project or acquisition eventually proves not to be accretive to our cash flow per unit, our business, financial condition, results of operations and
ability to pay distributions to our members may be materially adversely affected.

Exposure to currency exchange rate fluctuations will result in fluctuations in our cash flows and operating results.

Currency exchange rate fluctuations could have an adverse effect on our results of operations. Historically, a portion of our revenue
has been generated in Canadian dollars, but we incur operating and administrative expenses in both U.S. dollars and Canadian dollars and financing expenses in U.S. dollars. If the Canadian dollar
weakens significantly, we would be required to convert more Canadian dollars to U.S. dollars to satisfy our obligations, which would cause us to have less cash available for distribution.

A
significant strengthening of the U.S. dollar could result in an increase in our financing expenses and could materially affect our financial results under U.S. GAAP. In
addition, because we report our operating results in U.S. dollars, changes in the value of the U.S. dollar also result in fluctuations in our reported revenues and earnings. In addition, under
U.S. GAAP, all foreign currency-denominated monetary assets and liabilities such as cash and cash equivalents, accounts receivable, restricted cash, accounts payable, long-term
debt, capital lease obligations and asset retirement obligations are revalued and reported based on the prevailing exchange rate at the end of the reporting period. This revaluation may cause us to
report significant non-monetary foreign currency exchange gains and losses in certain periods.

Our operations are subject to environmental and worker safety laws and regulations that may expose us to significant costs and liabilities.

Our natural gas storage activities are subject to stringent and complex federal, state, provincial and local environmental and worker
safety laws and regulations. We may incur substantial costs in order to conduct our operations in compliance with these laws and regulations. Moreover, new, stricter environmental laws, regulations or
enforcement policies could be implemented that significantly increase our compliance costs or the cost of any remediation of environmental contamination that may

22

Table of Contents

become
necessary, and these costs could be material. In addition, laws and regulations to reduce emissions of greenhouse gases could affect the production or consumption of natural gas and, adversely
affect the demand for our storage services and the rates we are able to charge for those services. See "BusinessRegulation" for more information.

A change in the jurisdictional characterization of our assets by regulatory agencies or a change in policy by those agencies may result in increased regulation of our
assets, which may cause our revenues to decline and operating expenses to increase.

AECO Hub in Alberta is not currently subject to rate regulation. The Alberta Energy Resources Conservation Board, or the
ERCB, has jurisdiction to regulate the technical aspects of construction, development, and operation of storage facilities. If approved to do so by the Alberta Government, the AUC, may also set prices
for gas stored in Alberta. It is not currently Alberta Government policy to disturb market-based prices of independent gas storage facilities. If, however, the AUC was authorized to regulate the rates
we charge, it could materially adversely affect our business. In addition, a connected pipeline tolling structure is available to our customers at AECO Hub, allowing them to inject and
withdraw natural gas without incremental transportation costs. There has been a decision to include the previously provincially-regulated Alberta System under the jurisdiction of the Federal National
Energy Board, or NEB, and it is possible that the NEB could assume federal jurisdiction over, and set rates for, connected storage facilities, including AECO Hub, or invoke transportation
toll design changes that negatively impact AECO Hub.

Our
Wild Goose operations are regulated by the CPUC. The CPUC has authorized us to charge our Wild Goose customers market-based rates because, as an independent storage provider, we,
rather than ratepayers, bear the risk of any underutilized or discounted storage capacity. If the CPUC changes this determination, for instance as a result of a complaint, we could be limited to
charging rates based on our cost of providing service plus a reasonable rate of return, which could have an adverse impact on our revenues associated with providing storage services.

Our
Salt Plains operations are subject to primary regulation by the OCC and are permitted to conduct a limited amount of storage service in interstate commerce under Federal Energy
Regulatory Commission, or FERC, regulations and policies that allow pipeline and storage companies to engage in interstate commerce (commonly known as NGPA section 311 services under the
Natural Gas Policy Act of 1978), which services are not subject to FERC's broader jurisdiction under the Natural Gas Act. These section 311 services are provided by Salt Plains pursuant to a
Statement of Operating Conditions which is on file with FERC. FERC has permitted Salt Plains to charge market-based rates for its section 311 services. Market-based rate authority allows Salt
Plains to negotiate rates with individual customers based on market demand. This right to charge market-based rates may be challenged by a party filing a complaint with FERC. Our market-based rate
authorization may also be re-examined if we add substantial new storage capacity through expansion or acquisition and as a result obtain market power. Any successful complaint or protest
against our rates, or re-examination of those rates by FERC, could limit us to charging rates based on our cost of providing service plus a reasonable rate of return, and could have an
adverse impact on our revenues associated with providing storage services. Should FERC or the OCC change their relevant policies, or should we no longer qualify for primary regulation by the OCC, our
results of operations could be materially adversely affected.

Our
current natural gas storage operations in the United States are generally exempt from the jurisdiction of FERC, under the Natural Gas Act of 1938, or the Natural Gas Act or, in the
case of Salt Plains, are providing services under NGPA section 311. If our operations become subject to FERC regulation under the Natural Gas Act, such regulation may extend to such matters
as:



23

Table of Contents



In
the event that our operations become subject to FERC regulation, and should we fail to comply with all applicable FERC-administered statutes, rules, regulations and
orders, we could be subject to substantial penalties and fines. Under the Energy Policy Act of 2005, or EPAct 2005, FERC has civil penalty authority under the Natural Gas Act to impose penalties for
certain violations of up to $1,000,000 per day for each violation. FERC also has the authority to order disgorgement of profits from transactions deemed to violate the Natural Gas Act and the EPAct
2005.

We hold title to our storage reservoirs under various types of leases and easements, and our rights thereunder generally continue only for so long as we pay rent or, in some
cases, minimum royalties.

Our rights under storage easements and leases continue for so long as we conduct storage operations and pay our grantors for our use,
or otherwise pay rent owing to the applicable lessor. If we were unable to operate our storage facilities for a prolonged period of time (generally one year) or did not pay the rent or minimum
royalty, as applicable, to maintain such storage easements and leases in good standing, we might lose title to our gas storage rights underlying our storage facilities. In addition, title to some of
our real property assets may have title defects which have not historically materially affected the ownership or operation of our assets. In either case, to recover our lost rights or to remove the
title defects, we would be required to utilize significant time and resources. In addition, we might be required to exercise our power of condemnation to the extent available. Condemnation proceedings
are adversarial proceedings, the outcomes of which are inherently difficult to predict, and the compensation we might be required to pay to the parties whose rights we condemn could be significant and
could materially adversely affect our business, financial condition, results of operations and ability to pay distributions to our members.

Our financial results are seasonal and generally lower in the second and third quarters of the calendar year, which may require us to borrow money in order to make
distributions to our members during these quarters.

Our cash expenditures related to our optimization activities are highest during summer months, and our cash receipts from our
optimization activities are highest during winter months. As a result, our results of operations for the summer are generally lower than for the winter. With lower cash flow during the second and
third calendar quarters, we may be required to borrow money in order to pay distributions to our members. Any restrictions on our ability to borrow money could restrict our ability to pay the minimum
quarterly distributions to our members.

Our risk management policies cannot eliminate all commodity price risk. In addition, any non-compliance with our risk management policies could result in
significant financial losses.

While our hedging policies are designed to minimize commodity price risk, some degree of exposure to unforeseen fluctuations in market
conditions remains. We have in place risk management systems that are intended to quantify and manage risks, including risks related to our hedging activities such as commodity price risk and basis
risk. We monitor processes and procedures to prevent unauthorized trading and to maintain substantial balance between purchases and future sales and delivery obligations. However, these steps may not
detect and prevent all violations of our risk management policies and procedures, particularly if deception or other intentional misconduct is involved. There is no assurance that our risk management
procedures will prevent losses that would

negatively
affect our business, financial condition, results of operations and ability to pay distributions to our members. See "Management's Discussion and Analysis of Financial Condition and Results
of OperationsRisk Management Policy and Practices."

New derivatives legislation could have an adverse impact on our ability to hedge risks associated with our business and on the cost of our hedging activities.

We use over-the-counter (OTC) derivatives products to hedge commodity risks and, to a lesser extent, our
interest rate and currency risks. Recent legislation has been adopted to increase the regulatory oversight of the OTC derivatives markets and impose restrictions on certain derivative transactions,
which could affect the use of derivatives in hedging transactions. Final regulations pursuant to this legislation defining which companies will be
subject to the legislation have not yet been adopted. If future regulations subject us to additional capital or margin requirements or other restrictions on our trading and commodity positions, they
could have an adverse effect on our ability to hedge risks associated with our business and on the cost of our hedging activities.

We may enter into commercial obligations that exceed the physical capabilities of our facilities.

We enter into LTF and STF contracts and proprietary optimization transactions based on our understanding of the injection, withdrawal
and working gas storage capabilities of our facilities as well as the expected usage patterns of our customers. If our understanding of the capabilities of our facilities or our expectations of the
usage by customers is inaccurate we may be obligated to customers to inject, withdraw or store natural gas in manners which our facilities are not physically able to satisfy. If we are unable to
satisfy our obligations to our customers we may be liable for damages, the customers could have the right to terminate their contracts with us, and our reputation and customer relationships may be
damaged.

Our operations could be affected by terrorist activities and catastrophic events that could result from terrorism.

In the event that our storage facilities are subject to terrorist activities, such activities could significantly impair our operations
and result in a decrease in revenues and additional costs to repair and insure our assets. The effects of, or threat of, terrorist activities could result in a significant decline in the North
American economy and the decreased availability and increased cost of insurance coverage. Any of these factors could have a material adverse effect on our business, financial condition, results of
operations and ability to pay distributions to our members.

We depend on a limited number of customers for a significant portion of our revenues. The loss of any of these customers could result in a decline in our revenues and cash
available to make distributions.

We rely on a limited number of customers for a significant portion of our revenues. The loss of all or a portion of the revenues
attributable to our key customers as a result of competition, creditworthiness, inability to negotiate extensions or replacements of contracts or otherwise, could have a material adverse effect on our
business, financial condition, results of operations and ability to pay distributions to our members.

Risks Related to Our Structure

Holdco currently controls our manager, which has sole responsibility for conducting our business and managing our operations. Our manager has delegated this responsibility
to our board, all of the members of which are appointed by our manager. Our manager and its affiliates, including Holdco, have conflicts of interest with us and limited fiduciary duties, and they may
favor their own interests to the detriment of our common unitholders.

Holdco owns and controls our manager. Our manager appoints all of the members of our board, which manages and operates us. Some of our
directors and executive officers are directors or officers of our manager or its affiliates, including Holdco. Although our board has a fiduciary duty to manage us in a manner beneficial to us and our
unitholders, our directors and officers have a fiduciary duty to manage our business in a manner beneficial to Holdco. Therefore, conflicts of interest may arise between Holdco and its affiliates,
including our manager, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts of interest, our board may favor our manager's own interests and the interests of
its affiliates over the interests of our common unitholders. These conflicts include the following situations:

Table of Contents



Affiliates of our manager, including Holdco and the Carlyle/Riverstone Funds and their portfolio company subsidiaries, are not limited in their ability to compete with us
and are not obligated to offer us the opportunity to pursue additional assets or businesses.

Our Operating Agreement among us, Holdco and others does not prohibit affiliates of our manager, including Holdco and the
Carlyle/Riverstone Funds, from owning assets or engaging in businesses that compete directly or indirectly with us. Holdco is pursuing a potential gas storage development project in western Canada and
currently holds the rights to build a salt dome cavern gas storage facility in Louisiana and a depleted reservoir in southern Texas. Holdco may but is not required to offer us the opportunity to
purchase these projects. Holdco may instead opt to develop these projects in competition with us. In addition, the Carlyle/Riverstone Funds and their portfolio companies may acquire, construct or
dispose of additional natural gas storage or other assets in the future, without any obligation to offer us the opportunity to purchase or construct any of those assets. The Carlyle/Riverstone Funds
and their affiliates are large, established participants in the energy industry and may have greater resources than we have, which may make it more difficult for us to compete with these entities with
respect to commercial activities as well as for acquisition opportunities. As a result, competition from these entities could adversely impact our business, financial condition, results of operations
and ability to pay distributions to our members.

Holders of our common units have limited voting rights and are not entitled to elect our manager or our directors.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and,
therefore, limited ability to influence management's decisions regarding our business. Unitholders will have no right to elect our manager or our board on an annual or other continuing basis. Our
board, including our independent directors, is chosen entirely by our manager. Unlike publicly-traded corporations, we do not conduct annual meetings of our unitholders to elect directors or conduct
other matters routinely conducted at annual meetings of stockholders of corporations. Furthermore, if the unitholders were dissatisfied with the performance of our manager, they have little ability to
remove our manager.

We are a "controlled company" within the meaning of NYSE rules and, as a result, qualify for, and rely on, exemptions from some of the NYSE listing requirements with respect
to independent directors.

Because Holdco controls more than 50% of the voting power for the election of our directors, we are a controlled company within the
meaning of NYSE rules, which exempt controlled companies from the following corporate governance requirements:



For
so long as we remain a controlled company, we are not required to have a majority of independent directors or nominating, corporate governance or compensation committees.
Accordingly, our unitholders may not have the same protections afforded to shareholders of companies that are subject to all of the NYSE corporate governance requirements.

Our Operating Agreement limits our manager's and directors' fiduciary duties to holders of our common units and restricts the remedies available to holders of our common
units for actions taken by our manager or board that might otherwise constitute breaches of fiduciary duty.

Our Operating Agreement contains provisions that reduce the fiduciary standards to which our manager or directors would otherwise be
held by state fiduciary duty laws. The limitation and definition of these duties is permitted by the Delaware law governing limited liability companies. For example, our Operating
Agreement:

Even if unitholders are dissatisfied, they cannot initially remove our manager without Holdco's consent.

Unitholders have little ability to remove our manager. The vote of the holders of at least 662/3% of all outstanding
common and subordinated units voting together as a single class is required to remove our manager. Holdco owns 72.6% of our outstanding common and subordinated units. Accordingly, our public
unitholders are currently unable to remove our manager without Holdco's consent because Holdco owns sufficient units to be able to prevent the manager's removal.

If
our manager is removed without cause during the subordination period and no units held by the holders of the subordinated units or their affiliates are voted in favor of that removal,
all subordinated units held by our manager and its affiliates will automatically be converted into common units. If no units held by any holder of subordinated units or its affiliates are voted in
favor of that removal, all subordinated units will convert automatically into common units and any existing arrearages on the common units will be extinguished. A removal of our manager under these
circumstances would adversely affect the common units by prematurely eliminating their distribution and liquidation preference over the subordinated units, which would otherwise have continued until
we had met the tests specified in our Operating Agreement. Cause is narrowly defined in our Operating Agreement to
mean that a court of competent jurisdiction has entered a final, non-appealable judgment finding our manager liable for actual fraud or willful misconduct in its capacity as our manager.
Cause does not include most cases of poor management of the business.

Our manager, or its interest in us, may be transferred to a third party without unitholder consent.

Our manager may transfer its managing member interest to a third party in a merger or in a sale of all or substantially all of its
assets without the consent of our unitholders. Furthermore, our Operating Agreement does not restrict the ability of the owners of our manager from transferring ownership of our manager to a third
party. The new owners of our manager would then be in a position to revoke the delegation to our board of the authority to conduct our business and operations or to replace our directors and officers
with their own choices. This effectively permits a "change of control" of the company without unitholder vote or consent.

Increases in interest rates could adversely impact our unit price and our ability to issue additional equity to make acquisitions or for other purposes.

An increase in interest rates may cause a corresponding decline in demand for equity investments in general, and in particular for
yield-based equity investments such as our common units. Any such increase in interest rates or reduction in demand for our common units resulting from other relatively more attractive investment
opportunities may cause the trading price of our common units to decline. Therefore, changes in interest rates may affect our ability to issue additional equity to make acquisitions or for other
purposes.

It is our policy to distribute a significant portion of our available cash to our members, which could limit our ability to grow and make acquisitions.

Pursuant to our cash distribution policy, we expect that we will distribute a significant portion of our available cash to our members
and will rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital
expenditures. As a result, to the extent we are unable to finance growth externally, our cash distribution policy may impair our ability to grow.

In
addition, because we intend to distribute a significant portion of our available cash, our growth may not be as fast as that of businesses that reinvest their available cash to expand
ongoing operations. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, may impact the available
cash that we have to distribute to our members.

We may issue additional membership interests without unitholder approval, which would dilute a unitholder's existing ownership interests.

Our Operating Agreement does not limit the number of additional membership interests that we may issue at any time without the approval
of our unitholders. Our issuance of additional common units or other membership interests of equal or senior rank may have the following effects:



Our manager has a call right that may require unitholders to sell their common units at an undesirable time or price.

If at any time our manager and its affiliates own more than 80% of the common units, our manager will have the right, which it may
assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than their
then-current market price, as calculated pursuant to the terms of our Operating Agreement. As a result, unitholders may be required to sell their common units at an undesirable time or
price and may not receive any return on their investment. Unitholders may also incur a tax liability upon a sale of their units. Our manager is not obligated to obtain a fairness opinion regarding the
value of the

30

Table of Contents

common
units to be repurchased by it upon exercise of the call right. There is no restriction in our Operating Agreement that prevents our manager from issuing additional common units and exercising
its call right. If our manager exercised its call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our manager and its affiliates own approximately 48.2% of our outstanding common units. At the end of the
subordination period, assuming no additional issuances of common units (other than for the conversion of the subordinated units into common units), our manager and its affiliates will own
approximately 74.6% of our outstanding common units.

Our Operating Agreement restricts the voting rights of unitholders owning 20% or more of our common units.

Our Operating Agreement restricts unitholders' voting rights by providing that any units held by a person or group that owns 20% or
more of any class of units then outstanding, other than our manager and its affiliates, their transferees and persons who acquired such units with the prior approval of our board, cannot vote on any
matter. Our Operating Agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting the
unitholders' ability to influence the manner or direction of management.

Unitholders may have liability to repay distributions that were wrongfully distributed to them.

Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under
Section 18-607 of the Delaware Limited Liability Company Act, or the Delaware Act, we may not make a distribution to unitholders if the distribution would cause our liabilities to
exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of an impermissible distribution, members who received the distribution and who knew at the
time of the distribution that it violated Delaware law will be liable to the limited liability company for the distribution amount. A purchaser of common units will be liable for the obligations of
the transferor to make contributions to us that are known to such purchaser at the time it became a member and for unknown obligations if the liabilities could be determined from our Operating
Agreement.

The market price of our common units could be adversely affected by sales of substantial amounts of our common units in the public or private markets, including sales by
Holdco or other large holders.

We have 33,804,745 common units and 33,804,745 subordinated units outstanding. 16,304,745 of the common units and all of the
subordinated units are owned by Holdco. All of the subordinated units will convert into common units at the end of the subordination period, which could occur as early as the distribution in respect
of the quarter ending March 31, 2013. Sales by Holdco or other large holders of a substantial number of our common units in the public markets, or the perception that such sales might occur,
could have a material adverse effect on the price of our common units or could impair our ability to obtain capital through an offering of equity securities. In addition, we provided registration
rights to Holdco. Under our Operating Agreement, our manager and its affiliates have additional registration rights relating to the offer and sale of any units that they hold, subject to certain
limitations.

Tax Risks to Common Unitholders

Our tax treatment depends on our being treated as a partnership for U.S. federal income tax purposes and having no liability for U.S. federal income tax. If the U.S.
Internal Revenue Service, or the IRS, were to treat us as a corporation for U.S. federal income tax purposes, then our cash available for distribution to unitholders would be substantially reduced.

The anticipated after tax economic benefit of an investment in our common units depends largely on us being treated as a partnership
for U.S. federal income tax purposes. However, it is possible in certain circumstances for a limited liability company such as us to be treated as a corporation for U.S. federal income tax purposes.
Although we do not believe that we will be so treated based upon our current operations, a change in our business (or a change in current law) could cause us to be treated as a corporation for U.S.
federal income tax purposes or otherwise subject us to taxation as an entity.

If
we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax rate. We may also be liable for
state income taxes in addition to federal income taxes. Distributions to unitholders would generally be taxed again as corporate dividends, and no income, gains, losses or deductions would flow
through to them. Because corporate income taxes would be imposed upon us, our cash available for distribution to unitholders would be substantially reduced, likely causing a substantial reduction in
the value of our common units.

Our
Operating Agreement provides that the adverse impact of any such additional entity-level taxation will be borne by all members.

Notwithstanding our treatment for U.S. federal income tax purposes, we are subject to certain non-U.S. taxes. If a taxing authority were to successfully assert
that we have more tax liability than we anticipate or legislation were enacted that increased the taxes to which we are subject, the cash available for distribution to unitholders could be further
reduced.

Most of our business operations and subsidiaries are subject to income, withholding and other taxes in the non-U.S.
jurisdictions in which they are organized or from which they receive income, reducing the amount of cash available for distribution. In computing our tax obligation in these non-U.S.
jurisdictions, we are required to take various tax accounting and reporting positions on matters that are not entirely free from doubt and for which we have not received rulings from the governing tax
authorities, such as whether withholding taxes will be reduced by the application of certain tax treaties. Upon review of these positions the applicable authorities may not agree with our positions. A
successful challenge by a tax authority could result in additional tax being imposed on us, reducing the cash available for distribution to unitholders. In addition, changes in our operations or
ownership could result in higher than anticipated tax being imposed in jurisdictions in which we are organized or from which we receive income and further reduce the cash available for distribution.
Although these taxes may be properly characterized as foreign income taxes, unitholders may not be able to credit them against their liability for U.S. federal income taxes on their share of our
earnings.

Our
Operating Agreement provides that the adverse impact of any such additional entity-level taxation will be borne directly or indirectly by all members.

If we were subjected to a material amount of additional entity-level taxation by individual states and localities, it would reduce our cash available for distribution to
unitholders.

Changes in current state law may subject us to additional entity-level taxation by individual states and localities, reducing our cash
available for distribution to unitholders. Because of widespread state budget deficits and other reasons, several states are evaluating ways to subject partnerships and limited liability companies to
entity-level taxation through the imposition of state income, franchise and other

forms
of taxation. Our Operating Agreement provides that the adverse impact of any such additional entity-level taxation will be borne by all members.

Recently proposed legislation in Canada relating to the taxation of partners in a Canadian partnership could result in a significant increase in Canadian taxes paid over the
next five years.

Under Canadian tax law, partners in a partnership report their shares of the partnership's income or loss each year. When the
partnership uses a different tax year than the partner, the partner generally takes into account the income or loss accrued for the partnership year that ends within the partner's tax year. Under
legislation recently proposed in the Canadian parliament, however, certain partners would be required to accrue their shares of the partnership's income through the end of the partners' tax years
(even if the partnership's year has not yet ended). Changes to this system can result in the partner being required to report more than one year of the partnership's income for a single tax year.

Certain
of our subsidiaries are partners in partnerships and would be required to report additional income and pay additional Canadian income taxes under the proposed legislation.
Although we would be allowed to spread the accelerated income over a prospective five year period, if such legislation were to be enacted in its current form, the amount of Canadian income taxes paid
by us could increase by a material amount, reducing the cash available for distribution to unitholders. At this time, we cannot predict the form of legislation that might ultimately be enacted or the
specific effects of that legislation on us

We may become a resident of Canada and have to pay tax in Canada on our worldwide income, which could reduce our earnings, and unitholders could then become taxable in
Canada in respect of their ownership of our units. Moreover, as a non-resident of Canada we may have to pay tax in Canada on our Canadian source income, which could reduce our earnings.

Under the Income Tax Act (Canada), or the Canadian Tax Act, a company that is resident in Canada is subject to tax in Canada on its
worldwide income, and unitholders of a company resident in Canada may be subject to Canadian capital gains tax on a disposition of its units and to Canadian withholding tax on dividends paid in
respect of such units.

Our
place of residence, under Canadian law, would generally be determined based on the place where our central management and control is, in fact, exercised. It is not our current
intention that our central management and control be exercised in Canada. Based on our operations, we do not believe that we are, nor do we expect to be, resident in Canada for purposes of the
Canadian Tax Act, and we intend that our affairs will be conducted and operated in a manner such that we do not become a resident of Canada under the Canadian Tax Act. However, if we were or become
resident in Canada, we would be or become subject under the Canadian Tax Act to Canadian income tax on our worldwide income. Further, unitholders who are non-residents of Canada may be or
become subject under the Canadian Tax Act to tax in Canada on any gains realized on the disposition of our units and would be or become subject to Canadian withholding tax on dividends paid or deemed
to be paid by us, subject to any relief that may be available under a tax treaty or convention.

Our tax treatment as a publicly-traded partnership, as a company with multinational operations as well as the tax treatment of an investment in our common units could be
subject to potential legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

The present tax treatment of publicly-traded partnerships, companies with multinational operations, or an investment in such entities
as Niska Gas Storage Partners LLC is complex and may be modified by administrative, legislative or judicial interpretation at any time. Any modification to the

33

---



Table of Contents

tax
laws, treaties and interpretations thereof may or may not be applied retroactively. Any such changes could negatively impact the value of an investment in our common units.

If a tax authority contests the positions we take, the market for our common units may be adversely impacted and the cost of any such contest will reduce our cash available
for distribution to unitholders.

The tax authorities may adopt positions that differ from the positions we take. It may be necessary to resort to administrative or
court proceedings to sustain some or all of the positions we take, and a court may not agree with these positions. Any contest with a tax authority may materially and adversely impact the market for
our common units and the price at which they trade. In addition, our costs of any contest with a tax authority will be borne by our members because the costs will reduce our cash available for
distribution.

Unitholders are required to pay taxes on their share of our income even if they do not receive any cash distributions from us.

Because our unitholders are treated as partners for U.S. federal income tax purposes to whom we allocate taxable income, which could be
different in amount than the cash we distribute, unitholders are required to pay any U.S. federal income taxes, Medicare taxes and, in some cases, state and local income taxes on their share of our
taxable income even if they receive no cash distributions from us. Unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax
liability that results from that income.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If unitholders sell their common units, they will recognize a gain or loss for U.S. federal income tax purposes equal to the difference
between the amount realized and their tax basis in those common units. Because for U.S. federal income tax purposes distributions in excess of their allocable share of our net taxable income decrease
their tax basis in their common units, the amount, if any, of such prior excess distributions with respect to the units they sell will, in effect, become taxable income to them for U.S. federal income
tax purposes if they sell such units at a price greater than their tax basis in those units, even if the price they receive is less than their original cost. Furthermore, a substantial portion of the
amount realized, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. In addition, because the amount realized includes
a unitholder's share of our liabilities, unitholders may incur a tax liability on the sale of their units in excess of the amount of cash they receive.

Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investment in common units by a tax-exempt entity, such as employee benefit plans and individual retirement accounts (known
as IRAs), or a non-U.S. person raises issues unique to them. For example, virtually all of our income allocated to organizations that are exempt from U.S. federal income tax, including
IRAs and other retirement plans, is unrelated business taxable income and will be taxable to them. In addition, we expect to withhold taxes from distributions to non-U.S. persons at the
highest applicable effective tax rate, and non-U.S. persons are required to file U.S. federal tax returns and pay tax on their shares of our taxable income attributable to our U.S.
operations. Tax exempt entities (or those who intend to hold our units through an IRA) and non-U.S. persons should consult a tax advisor before investing in our common units.

Table of Contents

We treat each unitholder as having the same tax benefits without regard to the actual common units held. The IRS may challenge this treatment, which could adversely affect
the value of the common units.

Because we cannot match transferors and transferees of common units and because of other reasons, we have adopted depreciation and
amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS challenge to those positions could adversely affect the amount of taxable income
recognized by unitholders as a result of their ownership of our units. It also could affect the amount of gain from a unitholder's sale of common units and could have a negative impact on the value of
our common units or result in audit adjustments to that unitholder's tax returns.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first day
of each month, instead of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among our
unitholders.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the
ownership of our units on the first day of each month, instead of the date a particular unit is transferred. The use of this proration method may not be permitted under existing Treasury Regulations.
Recently, however, the Department of the Treasury issued proposed Treasury Regulations that provide a safe harbor pursuant to which a
publicly- traded partnership may use a similar monthly simplifying convention to allocate tax items among transferor and transferee unitholders. Although existing publicly-traded partnerships are
entitled to rely on these proposed Treasury Regulations, they are not binding on the IRS and are subject to change until final Treasury Regulations are issued. Moreover, our method of proration
differs from the proposed Treasury Regulations with respect to allocations of certain items of income and loss. Our counsel has not rendered an opinion regarding the validity of our proration method.

The amount of taxable income or loss allocable to each unitholder depends, in part, upon values that we periodically determine for our outstanding equity interests and our
assets in order to comply with federal income tax law. The IRS may challenge our determinations of these values, which could adversely affect the value of our units.

U.S. federal income tax law requires us to periodically determine the value of our assets and to calculate the amount of taxable income
or loss allocable to each partner based in part upon these values. We determine these asset values and allocations in part by reference to values that we determine for our outstanding equity
interests. The IRS may challenge our valuations and related allocations. A successful IRS challenge to these valuations or allocations could adversely affect the amount of taxable income or loss being
allocated to our unitholders. It also could affect the amount of gain from a unitholder's sale of units and could have a negative impact on the value of units or result in audit adjustments to our
unitholders' tax returns without the benefit of additional deductions.

A unitholder whose units are loaned to a "short seller" to cover a short sale of units may be considered as having disposed of those units. If so, such unitholder would no
longer be treated as the owner of those units for tax purposes during the period of the loan and may recognize gain or loss from the disposition.

Because a unitholder whose units are loaned to a "short seller" to cover a short sale of units may be considered as having disposed of
the loaned units, such unitholder may no longer be treated for tax purposes as an owner with respect to those units during the period of the loan to the short seller and the unitholder may recognize
gain or loss from such disposition. Moreover, during the period of the loan to the short seller, any of our income, gain, loss or deduction with respect to those units may not be reportable by the
unitholder and any cash distributions received by the unitholder in respect of those units could be fully taxable as ordinary income. Our counsel has not rendered an opinion

35

Table of Contents

regarding
the treatment of a unitholder whose common units are loaned to a short seller. Unitholders desiring to assure their status as owners of units for tax purposes and avoid the risk of gain
recognition from a loan to a short seller should modify any applicable brokerage account agreements to prohibit their brokers from loaning their units.

The sale or exchange of 50% or more of our capital and profits interests during any twelve-month period will result in the termination of our tax partnership for U.S.
federal income tax purposes.

We will be considered to have terminated our tax partnership for U.S. federal income tax purposes if there is a sale or exchange of 50%
or more of the total interests in our capital and profits within a twelve-month period. For purposes of determining whether the 50% threshold has been met, multiple sales of the same interest will be
counted only once. Our termination would, among other things, result in the closing of our taxable year for all unitholders, which would result in us filing two tax returns for one fiscal year and may
result in a significant deferral of depreciation deductions allowable in computing our taxable income. In the case of a unitholder reporting on a taxable year other than a calendar year, the closing
of our taxable year may also result in more than twelve months of our taxable income or loss being includable in his taxable income for the year of termination. Our termination currently would not
affect our classification as a partnership for federal income tax purposes, but it would result in our being treated as a new partnership for tax purposes. If we were treated as a new partnership, we
would be required to make new tax elections and could be subject to penalties if we were unable to determine that a termination occurred.

Unitholders are likely subject to state and local taxes and return filing requirements in jurisdictions where we operate or own or acquire property.

In addition to U.S. federal income taxes, unitholders are likely subject to state and local taxes, unincorporated business taxes and
estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we conduct business or own property now or in the future, even if they do not live in any of those
jurisdictions. Unitholders are likely required to file state and local income tax returns and pay state and local income taxes in some or all of these jurisdictions. Further, unitholders may be
subject to penalties for failure to comply with those requirements. We own assets and conduct business in California, Oklahoma and Texas. Each of California and Oklahoma currently imposes a personal
income tax on individuals. Many states also impose an income tax on corporations and other entities. As we make acquisitions or expand our business, we may own assets or conduct business in additional
states that impose a personal income tax. It is the unitholder's responsibility to file all U.S. federal, foreign, state and local tax returns. Our counsel has not rendered an opinion on the state or
local tax consequences of an investment in our common units.

None.

Item 2.    Properties.

Our storage facilities are constructed and maintained on property owned by others. Rights to use our reservoirs for natural gas storage
are held pursuant to natural gas storage leases with the surface owners of the lands where the reservoirs are situated as well as mineral owner agreements and similar instruments entered into with the
holders of subsurface mineral interests in such lands. Rights for the lands used for our pipelines are derived from right-of-ways, easements, leases and other similar
land-use agreements.

Item 5.    Market for Registrant's Common Equity, Related Shareholder Matters and Issuer Purchases of Equity Securities.



As of June 10, 2011, we had outstanding 33,804,745 common units, 33,804,745 subordinated units, a 2% managing member interest
and incentive distribution rights, or IDRs. The common units and subordinated units together represent all of our limited partner interests and 98% of our total ownership interests, in each case
excluding our IDRs. As discussed below under "Our Cash Distribution PolicyIncentive Distribution Rights," the IDRs represent the right to receive increasing percentages, up to a maximum
of 48%, of the cash we distribute from operating surplus (as defined below) in excess of $0.4025 per unit per quarter. Holdco currently owns approximately 48.2% of our outstanding common units, all of
our subordinated units and all of our IDRs.

Our
common units, which represent limited liability company interests in us, are listed on the NYSE under the symbol "NKA." Our common units have been traded on the NYSE since
May 12, 2010. Prior to that time, there was no public market for our stock. The following table sets forth for the indicated periods the high and low sales prices per unit for our common units

We generally make quarterly cash distributions of substantially all of our available cash, generally defined as consolidated cash receipts less consolidated cash
expenditures and such retentions for working capital, anticipated cash expenditures and contingencies as our manager deems appropriate. Distributions of cash paid by us to a unitholder will not result
in taxable gain or income except to the extent the aggregate amount distributed exceeds the tax basis of the Common Units owned by the unitholder.

We
are a publicly traded LLC and are not subject to federal income tax on our U.S.-sourced income. Instead, unitholders are required to report their allocable share of our income,
gain, loss and deduction, regardless of whether we make distributions. We have made quarterly distribution payments since August 2010.

We
are subject to withholding taxes by the Canada Revenue Agency ("CRA") for the portion of our quarterly distributions that are derived from our Canadian operations. Unitholders receive
foreign tax credits equal in amount to the amount that we pay to the CRA and can apply these credits against other Canadian sourced income, to the extent that they may have any.

The
following graph reflects the changes in closing prices from May 12, 2010, the first trading day of our common units on the NYSE, through March 31, 2011:

GRAPHIC



As of June 10, 2010, there were 4 holders of record of our common units. The number of record holders does not include holders
of units in "street names" or persons, partnerships, associations, corporations or other entities identified in security position listings maintained by depositories.



Our Operating Agreement contains a policy pursuant to which we pay regular quarterly cash distributions in an aggregate amount equal to
substantially all of our available cash. Under the policy, each quarter our board makes a determination of the amount of cash available for distribution to members. Our board determines cash available
for distribution to be an amount equal to all cash on hand at the end of the quarter, less reserves for the prudent conduct of our business (including

38

---



Table of Contents

reserves
for capital expenditures, operating expenditures and debt service) or for distributions to members in respect of future quarters. Our board's determination of available cash takes into
account the need to maintain certain cash reserves to preserve our distribution levels across seasonal and cyclical fluctuations in our business. Our board may determine to reserve or reinvest excess
cash in order to permit gradual or consistent increases in quarterly distributions and may borrow to fund
distributions in quarters when we generate less available cash than necessary to sustain or grow our cash distributions per unit.

Consistent
with our Operating Agreement, our board has, to date, declared a minimum quarterly distribution of $0.35 per unit per complete quarter, or $1.40 per unit per year, for each
complete fiscal quarter since our IPO. This equates to an aggregate cash distribution of approximately $24.1 million per quarter or $96.6 million per year, in each case based on the
number of common units and subordinated units and the 2% managing member interest currently outstanding. These distributions reflect the Board's basic judgment that our unitholders will be better
served by our distributing our available cash, after expenses and reserves, rather than retaining it. Because we believe we will generally finance any expansion capital investments from external
financing sources, including commercial bank borrowings and the issuance of debt and equity interests, we believe that our investors are best served by our distributing all of our available cash.
Because we are not subject to entity-level U.S. federal income tax, we will have more cash to distribute to unitholders than would be the case if we were subject to such tax.



Our manager is entitled to 2% of all distributions that we make prior to our liquidation. Our manager has the right, but not the
obligation, to contribute a proportionate amount of capital to us to maintain its current managing member interest if we issue additional membership interests in the future. The manager's initial 2%
interest in distributions will be reduced if we issue additional membership interests in the future and our manager does not contribute a proportionate amount of capital to us to maintain its 2%
managing member interest.



Incentive distribution rights represent the right to receive an increasing percentage (13%, 23% and 48%) of quarterly distributions of
cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. Holdco holds the incentive distribution rights but may transfer these
rights, subject to restrictions in our Operating Agreement.

If
for any quarter:



then
additional distributions from operating surplus for that quarter will be made in the following manner:

In
each case, the amount of the target distribution set forth above is exclusive of any distributions to common unitholders to eliminate any cumulative arrearages in payment of the
minimum quarterly distribution.



There is no guarantee that unitholders will receive quarterly cash distributions from us. Our distribution policy may be changed at any
time and is subject to certain restrictions, including:

Sales of Unregistered Securities

In connection with our IPO, we issued 13,679,745 common units and 33,804,745 subordinated units to Holdco and its affiliates, which
contributed to us our natural gas storage assets. On June 11, 2010, upon the expiration of the underwriters overallotment option, we issued an additional 2,625,000 common units to Holdco. These
units were issued in private placements exempt from registration under the Securities Act.

Use of Proceeds from the Sales of Registered Securities

On May 17, 2010, we completed our IPO of common units pursuant to a Registration Statement on Form S-1, as
amended (Reg. No. 333-165007),
that was declared effective on May 10, 2010. Under the registration statement, we sold an aggregate of 17,500,000 common units to the public at a price of $20.50 per common unit. Goldman,
Sachs & Co., Morgan Stanley & Co. Incorporated, Barclays Capital Inc., Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, RBC Capital
Markets Corporation, and UBS Securities LLC acted as joint book-running managers of the offering. The offering commenced on April 30, 2010 and closed on May 17, 2010.
As a result of our IPO, we raised a total of $358.8 million in gross proceeds, and approximately $331.4 million in net proceeds after deducting underwriting discounts and commissions of
$22.0 million, structuring fees of $1.3 million and offering expenses of approximately $4.0 million.

We
used approximately $271.4 million of the net proceeds of this offering to fully repay all borrowings under our revolving credit facilities. We have used the remainder for
general company purposes, including funding a portion of the cost of our expansion projects.

Equity Compensation Plan

As of March 31, 2011, there were no equity compensation plans providing for issuances of equity securities of the registrant.
See "Item II. Executive CompensationCompensation Discussion and AnalysisLong-Term Incentive Plan" for information about our Long-Term Incentive
Plan, which became effective at the time of our IPO.

Item 6.    Selected Financial Data.

The following table shows selected historical consolidated financial and operating data of Niska Gas Storage Partners LLC for
the fiscal year ended March 31, 2011, and Niska Predecessor, consisting of the combined financial statements of Niska GS Holdings I, L.P. and Niska GS Holdings II, L.P. for the
fiscal years ended March 31, 2010, 2009 and 2008 and for the period from May 12, 2006 to March 31, 2007. Niska Predecessor acquired our predecessor business from EnCana
Corporation in a two step transaction. In the first step of the transaction, which closed on May 12, 2006, Niska Predecessor acquired all of our assets except Wild Goose. In the second phase of
the transaction, which closed on November 16, 2006, Niska Predecessor acquired Wild Goose. This document does not include financial statements relating to the assets prior to their acquisition
by Niska Predecessor because of the reasons explained below. As a result, the financial statements of Niska Predecessor for the period ended March 31, 2007 are not directly comparable to
financial statements for subsequent periods.

Financial
information for periods prior to May 12, 2006 and for Wild Goose for periods prior to November 16, 2006 is not presented. Niska Predecessor was provided with
historical financial data for the years ended December 31, 2003, 2004 and 2005 prepared by EnCana Corporation in accordance with Canadian GAAP. Niska Predecessor was not provided with any
financial information, audited or otherwise, for the periods from January 1, 2006 through May 11, 2006, in the case of all assets other than Wild Goose, or through November 16,
2006, in the case of Wild Goose. We are not affiliated in any way with EnCana Corporation and we are unable to prepare financial statements for the assets of

Niska
Predecessor for periods prior to the dates that Niska Predecessor acquired such assets from EnCana Corporation. We also do not have access to the information necessary to convert the financial
information prepared by EnCana Corporation from Canadian GAAP to U.S. GAAP. This financial information rests peculiarly within the knowledge of EnCana Corporation and cannot be obtained by
Niska Predecessor without unreasonable effort or expense. Niska Predecessor did not rely on the financial and operating data prepared by EnCana Corporation when it acquired the assets from EnCana
Corporation, and Niska Predecessor materially changed the operation of the assets after it acquired them and did not assume all of the liabilities and obligations associated with EnCana Corporation's
operation of the assets. Accordingly, the financial and operating data prepared by EnCana Corporation is not readily comparable to Niska Predecessor's financial statements. We, and our auditors, are
unable to verify the financial information prepared by EnCana Corporation. In particular, any intercompany profits arising from transactions between the Canadian and U.S. operations (and other EnCana
Corporation subsidiaries) cannot be identified and as such, profits that would have been generated from such transactions are not eliminated from revenues and expenses. Additionally, the financial
statements prepared by EnCana Corporation for its Canadian operations do not include a line item or narrative regarding taxes and we are unable to determine the appropriateness of the exclusion of
taxes from the financial statements.

The
historical consolidated financial data presented for the year ended March 31, 2011 and the combined financial data presented for the years ended March 31, 2010, 2009
and 2008 and the period from May 12, 2006 to March 31, 2007 is derived from audited financial statements for those respective periods, and should be read together with and is qualified
in its entirety by reference to, the historical audited consolidated and combined financial statements, respectively of Niska Gas Storage Partners LLC and Niska Predecessor and the accompanying
notes included in Item 8.

Moreover,
the table should be read together with "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in Item 7.

We use the non-GAAP financial measure Adjusted EBITDA in this report. A reconciliation of Adjusted EBITDA to net earnings,
its most directly comparable financial measure as calculated and presented in accordance with GAAP, is shown above.

We
define Adjusted EBITDA as net earnings before interest, income taxes, depreciation and amortization, unrealized risk management gains and losses, foreign exchange gains and losses,
unrealized inventory impairment writedowns, gains and losses on asset dispositions, asset impairments and other income. We believe the adjustments for other income, which is comprised primarily of
income from an arbitration award granted to us in the fiscal year ended March 31, 2009, are similar in

45

Table of Contents

nature
to the traditional adjustments to net earnings used to calculate EBITDA and adjustment for these items results in an appropriate representation of this financial measure. Adjusted EBITDA is
used as a supplemental financial measure by our management and by external users of our financial statements such as commercial banks and ratings agencies, to assess:



The
GAAP measure most directly comparable to Adjusted EBITDA is net earnings. The non-GAAP financial measure of Adjusted EBITDA should not be considered as an alternative to
net earnings. Adjusted EBITDA is not a presentation made in accordance with GAAP and has important limitations as an analytical tool. Adjusted EBITDA should not be considered in isolation or as a
substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA excludes some, but not all, items that affect net earnings and is defined differently by different companies, our
definition of Adjusted EBITDA may not be comparable to similarly titled measures of other companies.

We
recognize that the usefulness of Adjusted EBITDA as an evaluative tool may have certain limitations, including:



How We Evaluate Our Operations

We generate substantially all of our revenue through long and short-term contracts for the storage of natural gas for
third-party customers and the proprietary optimization of storage capacity that is

46

---



Table of Contents

uncontracted,
underutilized or available only on a short-term basis. We evaluate our business on the basis of the following key measures:





We provide multi-year, multi-cycle storage services to our customers under LTF contracts. From our inception on
May 12, 2006 to March 31, 2011, we utilized an average of approximately 67.6% of our operated capacity for our LTF strategy. The volume weighted average life of our LTF contracts at
March 31, 2011 was 2.6 years. Under our LTF contracts, our customers are obligated to pay us monthly reservation fees which are fixed charges owed to us regardless of the actual use by
the customer. When a customer utilizes the capacity that is reserved under these contracts, we also collect a variable fee designed to allow us to recover our variable operating costs. Reservation
fees comprise over 90% of the revenue generated under LTF contracts and provide a baseline of revenue in excess of our general and administrative and operating costs. From inception to
March 31, 2011, our LTF contracts generated average revenues, including both reservation and variable fees, of $1.03 per Mcf. We evaluate both the volume and price of our LTF contracting, which
can indicate the effectiveness of our marketing efforts as well as the relative attractiveness of LTF contracts in comparison to our other revenue strategies. During periods when prices are higher, we
will utilize more of our capacity under LTF contracts.



In addition, we provide short term services for customers under STF contracts. From inception to March 31, 2011, we utilized an
average of approximately 16.7% of our operated capacity for our STF strategy. STF contracts typically have terms of less than one year. Under an STF contract, a customer pays a fixed fee to inject a
specified quantity of natural gas on a specified date or dates and to store that gas in our storage facilities until withdrawal on a specified future date or dates. Because STF contracts set forth
specified future injection or withdrawal dates, we enter into offsetting transactions to capture incremental value as spot and future natural gas prices fluctuate prior to that activity date. We
monitor the volume used for and evaluate the fees generated under our STF contracts. The fees we are able to generate from our STF contracts reflect market conditions (including interest rates) and
the effectiveness of our marketing efforts. From inception to March 31, 2011, our STF contracts generated average revenues of $1.61 per Mcf. The capacity utilized for STF contracts
depends on, among other things, the total capacity of our storage facilities that is not being utilized for LTF contracts and the contract rates available for STF contracts.



From inception to March 31, 2011, we utilized an average of approximately 15.7% of our operated capacity and all of our NGPL
capacity for our proprietary optimization strategy. When market conditions warrant, we enter into economically hedged transactions with available capacity to achieve margins higher than can be
obtained from third-party contracts. Because we simultaneously hedge our

47

---



Table of Contents

transactions,
we are able to determine in advance the minimum margins that will be realized and add incremental margins by re-hedging as market conditions change.

At
times, if spreads move favorably, such as if winter gas prices fall below forward prices for the following summer, we can further increase margins that have been substantially locked
in by choosing to hold inventory into a subsequent period and re-hedging the transaction. This has the result of increasing our cash flow margins and overall profitability, although for
accounting purposes the income is deferred into a later period, causing the appearance of cyclicality in our reported revenues and profits.

When
evaluating the performance of our optimization business, we focus on our realized optimization margins, excluding the impact of unrealized hedging gains and losses and inventory
write-downs. For accounting purposes, our net realized optimization revenues include the impact of unrealized economic hedging gains and losses and inventory write-downs, which cause our reported
revenues to fluctuate from period to period. However, because substantially all inventory is economically hedged, any inventory write-downs are offset by hedging gains and any unrealized hedging
losses are offset by gains when the inventory is sold. From inception to March 31, 2011, our proprietary optimization business generated average margins of $2.61 per Mcf on a realized basis
before unrealized marked to market gains and losses and inventory write-downs.



Our most significant operating expenses are fuel and electricity costs. These operating expenses vary significantly based upon the
amount of gas we inject or withdraw throughout the year and the price of the energy commodity at the time of purchase. Variable operating expenses are partially offset by the variable fees we collect
from our LTF contracts. The smaller, fixed component of our operating expenses include salaries and labor, parts and supplies, surface and mineral lease rentals and other general operating costs.
These fixed operating expenses are more stable from year to year but can fluctuate due to unforeseen repairs, equipment malfunctions and overhauls of compressors or engines.



Our general and administrative expenses primarily consist of employee compensation, legal, accounting and tax fees and our office
lease.



We define Adjusted EBITDA as net earnings before interest, income taxes, depreciation and amortization, unrealized risk management
gains and losses, foreign exchange gains and losses, unrealized inventory impairment writedown, gains and losses on asset dispositions, asset impairments and other income. Our Adjusted EBITDA is not a
presentation made in accordance with GAAP. We utilize Adjusted EBITDA in order to be able to compare our results against our peers, regardless of differences in financing, and by excluding
non-recurring items to be able to compare to our own results for other periods.



We regularly monitor our leverage statistics to ensure a conservative capital structure. As of March 31, 2011, we had a debt to
Adjusted EBITDA ratio of 4.1x, debt to capitalization of 47%, and a fixed charge coverage ratio of 2.5x. We expect to maintain or improve
these ratios over time in order to maintain access to available capital markets, a competitive cost of capital and financial flexibility to grow our business and increase our cash distributions.

Funding the purchase of proprietary optimization inventory can consume a significant portion of our available working capital. In times
of higher natural gas prices, holding large inventories of proprietary gas may cause us to consume a substantial portion of our availability under our credit facilities. We therefore closely monitor
the utilization and remaining available capacity under our credit facilities and actively pursue additional STF contracts when we determine it is appropriate to maintain liquidity.

Factors that Impact Our Business

Factors that impact the performance of specific components of our business from period to period include the following:



The price available in the marketplace when negotiating new or replacement LTF contracts reflects demand and affects the amount of
storage capacity utilized for LTF contracts that year, and thus the amount of capacity utilized for STF contracts or proprietary optimization for that year. We may increase the capacity that we use
for LTF contracts at times of higher market prices and demand. Lower market prices for LTF contracts may result from lower seasonal spreads or a more competitive environment for storage services.



Capacity added in the prior year or added during a year is expected to generate incremental revenue.



When winter gas prices fall below forward prices for the following summer, we may defer the withdrawal of proprietary optimization
inventory until the next fiscal year in order to add incremental margin and economic value. This results in the deferral of realized earnings and cash flow from one fiscal year to the next. In some
cases, we can mitigate the impact of deferred earnings and cash flow by entering into STF contracts that straddle the two fiscal years.



The variable operating costs of our facilities (mostly comprised of costs associated with fuel or electricity for compressor
operations) are affected by the amount and price of energy used to inject and withdraw gas from our facilities and by the number and timing of gas injections and withdrawals. For example, if we
experience large injections of gas in the early summer (instead of a steady rate of injections throughout the summer) we would have greater than expected costs in our first quarter and lower than
expected costs in our second quarter. A mild winter could lead to less withdrawals in total, and therefore lower overall variable costs. These cost variances would be partially offset by similar
variances in contract revenues.



Our cost of capital and the amount of our working capital availability impacts the amount of capacity utilized for proprietary
optimization as compared to STF contracts. A higher cost of capital relative to that of our customers or less availability will generally lead to less volume used for proprietary optimization
transactions. In general, higher carrying costs for us or our customers result in lower margins for us.

49

---



Table of Contents



Incremental revenue opportunities in the form of STF or proprietary optimization transactions may arise for us if capacity usage by our
LTF customers is underutilized or offset by other LTF customers.



Weather extremes and variability directly affect our margins. Very mild years tend to reduce revenue generated under our STF and
proprietary optimization strategies, while years with very hot summers, very cold winters or a number of significant storms tend to increase the revenue generated under those strategies.

Segment Information

Our process for the identification of reportable segments involves examining the nature of services offered, the types of customer
contracts entered into and the nature of the economic and regulatory environment. Since our inception, we have operated along functional lines in our commercial, engineering and operations teams for
operations in Alberta, northern California and the U.S. midcontinent. All functional lines and facilities offer the same services: firm storage contracts, short-term firm services and
optimization. All services are delivered using reservoir storage. We measure profitability consistently along all functional lines based on revenues and earnings before interest, taxes, depreciation
and amortization, before unrealized risk management gains and losses. We have aggregated our functional lines and facilities into one reportable segment as at and for the fiscal years ended
March 31, 2011, 2010 and 2009.

Information
pertaining to our LTF, STF and proprietary optimization revenues is presented in the consolidated and combined statements of earnings and comprehensive income. All facilities
have the same types of customers: major companies in the energy industry, industrial, commercial, and local distribution companies and municipal energy consumers.

Results of Operations

Fiscal Year Ended March 31, 2011 Compared to Fiscal Year Ended March 31, 2010

The fiscal year ended March 31, 2011 was characterized by an environment of stable natural gas prices and reduced volatility.
These factors combined to reduce seasonal natural gas storage spreads and limited revenue opportunities within our optimization and STF strategies. Notwithstanding these market conditions, we
generated $195.6 million of adjusted EBITDA and $117.6 million of cash available for distribution. In addition, we continued our organic strategy by expanding our facilities by 19.0 Bcf
at a cost of approximately $1.86/ Mcf (including accrued expenditures and transfers of cushion gas).

Revenue.Revenues for the fiscal year ended March 31, 2011 decreased by 14.9% to $230.1 million from $270.5 million for
the
fiscal year ended March 31, 2010. This decrease was primarily attributable to the following:

Net Earnings.Net earnings for the fiscal year ended March 31, 2011 increased by 8.1% to $57.5 million from
$53.2 million for
the fiscal year ended March 31, 2010. This change was primarily attributable to the lower pre-tax earnings discussed above, offset by the following:

Income Tax Expense/(Benefit).We recorded an income tax benefit of $30.1 million for the fiscal year ended March 31, 2011
compared to
an expense of $67.9 million for the fiscal year ended March 31, 2010. This change is in part due to a one-time expense in the prior period resulting from electing a U.S. tax
reporting currency for select Canadian entities. The change is also due to less income being earned in Canadian entities during the current period, combined with tax pools obtained
from assets purchased, and favorable assessments completed by taxation authorities. Taxes paid in the current year were $0.5 million, compared to $0.3 million in the fiscal year ended
March 31, 2010.

during the fiscal year ended March 31, 2010 eliminated material foreign currency translation gains and losses attributable to deferred income taxes. Foreign exchange gains were realized on the
settlement of Canadian dollar denominated receivables in an appreciating Canadian dollar environment.

Net Earnings.Net earnings for the fiscal year ended March 31, 2010 decreased by 51.1% to $53.2 million from

Seasonality and Quarterly Fluctuations

Our business is highly seasonal. In general, revenue is highest during our third and fourth fiscal quarters (October through March),
during the peak of the natural gas storage winter withdrawal season, when we typically sell most of our optimization inventory to serve the seasonal demand created by the North American residential
market which uses natural gas to heat their homes. Revenue is substantially lower in the first and second quarters (April through September), when natural gas prices are generally lower and we shift
to the storage injection season and replenish our natural gas inventory. In 2011, approximately 59.6% of our revenue was generated in the third and fourth quarters of our fiscal year.

Because
we typically purchase natural gas and build inventories in the summer months and hedge sales forward into the winter months, the peak borrowing on our revolving credit facilities
are generally highest in the middle of our third fiscal quarter, while our peak accounts receivable collections typically occur in our fourth fiscal quarter.

The
following table illustrates the differences in the recognition of revenue associated with our revenue strategies.

Liquidity and Capital Resources

Our primary short-term liquidity needs are to pay our quarterly distributions, to pay interest and principal payments under
our $400.0 million credit agreement and our senior notes, to fund our operating expenses, and maintenance capital and to pay for the acquisition of proprietary optimization inventory along with
associated margin requirements, which we expect to fund through a combination of cash on hand, cash from operations and borrowings under our $400.0 million credit agreement. Our
medium-term and long-term liquidity needs primarily relate to potential organic expansion opportunities and asset acquisitions. We expect to finance the cost of any expansion
projects and acquisitions from the proceeds of our IPO, borrowings under our existing and possible future credit facilities or a mix of borrowings and additional equity offerings as well as cash on
hand and cash from operations. We anticipate that our primary sources of funds for our long-term liquidity needs will be from cash from operations and/or debt or equity financings. We
believe that these sources of funds will be sufficient to meet our liquidity needs for the foreseeable future.

Because
we intend to distribute substantially all of our available cash, our growth may not be as fast as the growth of businesses that reinvest their available cash to expand ongoing
operations. Moreover, our future growth may be slower than our historical growth. We expect that we will, in large part, rely upon external financing sources, including bank borrowings and issuances
of debt and equity interests, to fund our expansion capital expenditures. To the extent we are unable to finance growth externally, our cash distribution policy could significantly impair our ability
to grow. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk
that we will be unable to maintain or increase our per unit distribution level, which in turn may affect the available cash that we have to distribute on each unit. Our Operating Agreement does not
limit our ability to issue additional units, including units ranking senior to the common units we offered in our IPO. The incurrence of additional debt by us or our operating subsidiaries would
result in increased interest expense, which in turn may also affect the available cash that we have to distribute to our unitholders.



Our cash flows are significantly influenced by our level of natural gas inventory, margin deposits and related forward sale contracts
or hedging positions at the end of each accounting period and may fluctuate significantly from period to period. In addition, our period-to-period cash flows are heavily
influenced by the seasonality of our proprietary optimization activities. For example, we generally purchase significant quantities of natural gas during the summer months and sell natural gas during
the winter months. The storage of natural gas for our own account can have a material impact on our cash flows from operating activities for the period we pay for and store the natural gas and the
subsequent period in which we receive proceeds from the sale of natural gas. When we purchase and store natural gas for our own account, we use cash to pay for the gas and record the gas as inventory
and thereby reduce our cash flows from operating activities. We typically borrow on our revolving credit facilities to fund these purchases, and these borrowings increase our cash flows from financing
activities. Conversely, when we collect the proceeds from the sale of natural gas that we purchased and stored for our own account, the impact on our cash flows from operating activities is positive
and the impact on our cash flows from financing activities is negative. Therefore, our cash flows from operating activities fluctuate significantly from period-to-period as we
purchase gas, store it, and then sell it in a later period. In addition, we have margin requirements on our economically hedged positions. As the cash deposits we make to satisfy our margin
requirements increase and decrease with our volume of derivative positions and changes in commodity prices, our cash flows from operating activities may

fluctuate
significantly from period to period. The following table summarizes our sources and uses of cash for the fiscal years ended March 31, 2011, 2010, and 2009:

Operating Activities.The variability in net cash provided by operating activities is primarily due to (1) varying market
conditions
that exist during any given fiscal period, which impacts the margins and fees under each of our LTF, STF and optimization activities; and (2) market conditions at the end of any given fiscal
period, which impacts our decision to sell significant volumes of inventory or hold them over a fiscal period end and sell them in the next fiscal period if there is the economic incentive to do so,
such as to increase the margins from previous optimization transactions.

For
the fiscal year ended March 31, 2010, the price of natural gas for the following summer was higher than the economically hedged price of our inventory. We thus chose to carry
some of our inventory over the year end and re-hedged its sale to the following fiscal year. This had the effect of increasing our aggregate margins and profitability, but deferred some
income and operating cash flow from the fiscal year ended March 31, 2009 to the fiscal year ended March 31, 2010. Unlike 2009, because we already had a significant opening inventory
balance at the beginning of the year, we did not show a significant use of cash for the purposes of purchasing inventory for the period ended March 31, 2010. $36.2 million of additional
margin deposits were provided during the period to provide collateral support for our financial hedges.

For
the fiscal year ended March 31, 2011, our facility expansions resulted in an increase in the amount of capacity that we optimized, and, because natural gas prices were higher
in the following summer than they were at the end of the prior year, we chose to carry a significant amount of our inventory into the following year. While we held slightly more inventory at year end
compared to March 31, 2010, lower prices offset some of the change in inventory value. In addition, forward natural gas prices rose after we economically hedged our inventory requiring us to
provide incremental margin deposits to cover our unrealized mark to market losses on the financial hedge positions.

Working Capital.Working capital is defined as the amount by which current assets exceed current liabilities. Our working capital ratio
is defined as
current assets divided by current liabilities. Our working capital requirements are primarily affected by our level of capital spending for maintenance and expansion activity, but are also impacted by
changes in accounts receivable and accounts payable. These changes are influenced by factors such as credit extended to, and the timing of collections from, our customers. Our working capital is also
affected by the relationship between unrealized financial risk management hedges which are marked-to-market on a monthly basis, the margin deposits required by our brokers for
such gains and losses, proprietary inventory which is stored in our facilities and cash used to fund inventory purchases.

As
of March 31, 2011, we had net working capital of $272.1 million (working capital ratio of 2.6 to 1.0), representing only a marginal change compared to net working
capital of $249.8 million (working capital ratio of 2.4 to 1.0) at March 31, 2010.

Investing Activities.Most of the investing activities in each of the fiscal years ended March 31, 2011, 2010 and 2009 were
attributed to
expansion capital expenditures at our storage facilities. These expenditures, as outlined in "Capital Expenditures," have enabled us to increase our effective working gas capacity by 49.2
Bcf during this period. However, maintenance capital expenditures have

59

---



Table of Contents

been
consistently modest, ranging between $0.9 million and $1.7 million each year during this same period.

Financing Activities.Net cash provided/(used) by financing activities consists of debt incurred for the acquisition of assets,
periodic optional and
mandatory retirements of such debt, advances and repayments made on our previous credit facilities to fund proprietary inventory purchases, contributions of capital from our equity holders to fund
expansion capital expenditures and debt retirements and distributions made to our equity holders.

During
the fiscal year ending March 31, 2009, we repaid $96.9 million of our term debt through a combination of cash provided from operations and a $50.0 million
equity infusion from our equity holders. During the same period, we drew $65.0 million under our previous credit facilities to fund some of our proprietary inventory purchases. We also made a
$48.5 million distribution to our equity holders to cover income tax obligations.

During
the fiscal year ending March 31, 2010 we drew $185.1 million from our previous credit facilities to fund proprietary inventory purchases and subsequently repaid
$175.0 million when the inventory was sold later in the year. During the fiscal year ended March 31, 2010, we issued our senior notes, which provided net proceeds of approximately
$775.4 million after deducting approximately $24.6 million of fees and expenses. (See "Our 8.875% Senior Notes Due 2018.") Approximately $102.2 million of the net
proceeds were used to make a distribution to our equity holders, approximately $75.0 million of the proceeds were used to repay our previous revolving credit facility and approximately
$592.5 million of the proceeds were used to repay our previous term loan. In connection with our issuance of senior notes and the repayment of our previous credit facility and term loan, we
entered into new senior secured asset-based revolving credit facilities, consisting of a U.S. revolving credit facility and a Canadian revolving credit facility (see "Our
$400 Million Credit Agreement.")

During
the fiscal year ending March 31, 2011 we received proceeds of $333.5 million from our IPO in May of 2010, after deducting fees of $23.4 million. This
was offset by distributions totaling $313.3 million made to the owners of Niska Predecessor in connection with our debt and equity offerings, and $64.7 million related to quarterly
distributions made to our unitholders during the period.

In
October of 2009 and January of 2010, the holders of our predecessor's Class A units made contributions to the capital of our predecessor totaling approximately
$15.0 million and $18.0 million, respectively in order to fund capital expenditures. During the fiscal year ending March 31, 2010, our predecessor made distributions totaling
approximately $129.0 million to its equity holders (inclusive of the $102.2 million distribution made from the proceeds of the senior notes).

Maintenance
capital expenditures are capital expenditures made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend
their useful lives. Expansion capital expenditures are made to acquire additional assets to grow our business, to expand and upgrade our facilities and to acquire similar operations or facilities.

Under
our current plan, we expect to continue to spend between approximately $1.0 million and $2.0 million per year for maintenance capital expenditures to maintain the
integrity of our storage facilities and ensure the reliable injection, storage and withdrawal of natural gas for our customers. In the fiscal year ended March 31, 2011, we spent a total of
$32.3 million, excluding $2.9 million of capital expenditures which were accrued at March 31, 2011 to expand the capacity and services of our facilities.



On March 5, 2010, Niska US and Niska Canada, closed a non-public offering of 800,000 units, each unit consisting of
$218.75 principal amount of 8.875% senior notes due 2018 of Niska US and $781.25 principal amount of 8.875% senior notes of Niska Canada. The units were sold in an offering exempt from registration
under the Securities Act to qualified institutional investors in reliance on Rule 144A under the Securities Act and to non-U.S. persons in offshore transactions in reliance on
Regulation S under the Securities Act.

On
February 3, 2011, the Securities and Exchange Commission ("SEC") accepted and made effective our exchange offer whereby holders of the current Senior Notes were permitted to
exchange such Senior Notes for new freely transferable Senior Notes. The terms of the new units are identical to the units which are described below, except that the new units are registered under the
Securities Act and generally do not contain restrictions on transfer.

In
this report we refer to the 8.875% senior notes due 2018 of Niska US and Niska Canada as "the notes" or "our senior notes." In this section Niska US and Niska Canada are each referred
to individually as an "issuer" and collectively as "the issuers."

The
notes are senior unsecured obligations of each issuer, which are: (1) effectively junior to that issuer's secured obligations; (2) equal in right of payment with all
existing and future senior unsecured indebtedness of each issuer; and (3) senior in right of payment to any future subordinated indebtedness of each issuer. The notes are fully and
unconditionally guaranteed by us and our direct and indirect subsidiaries on a senior unsecured basis, and are: (1) effectively junior to each guarantor's secured

obligations;
(2) equal in right of payment with all existing and future senior unsecured indebtedness of each guarantor and (3) senior in right of payment to any future subordinated
indebtedness of each guarantor.

Interest
on our senior notes is payable on March 15 and September 15 of each year they are outstanding. The notes will mature on March 15, 2018. Under the indenture
governing our senior notes, we are required to make principal payments prior to the maturity date except upon certain events of default. In addition, in the event of a change in control or certain
asset sales, as those terms are defined in the indenture, we may be required to offer to redeem the notes from our holders.

The
indenture governing our senior notes limits our ability to pay distributions in respect of, repurchase or pay dividends on our membership interests (or other capital stock) or make
other restricted payments. The limitation changes depending on our fixed charge coverage ratio, which is defined as the ratio of our consolidated cash flow to our fixed charges, each as defined in the
indenture governing our senior notes, and measured for the preceding four quarters.

If
the fixed charge coverage ratio is not less than 1.75 to 1.0, we will be permitted to make restricted payments if the aggregate restricted payments since the date of closing of our
IPO, excluding certain types of permitted payments, are less than the sum of a number of items including, most importantly:

As
of March 31, 2011, the indenture governing our senior notes would have permitted us to distribute approximately $150 million.

The
indenture does not prohibit certain types or amounts of restricted payments, including a general basket of $75.0 million of restricted payments.

The
indenture governing our senior notes contains certain other covenants that, among other things, limit our and certain of our subsidiaries' ability to:

Table of Contents

The occurrence of events involving us or certain of our subsidiaries may constitute an event of default under the indenture. Such events include failure to pay
interest, principal, or the premium on the notes when due; failure to comply with the merger, asset sale or change of control covenants; certain defaults on other indebtedness; and certain insolvency
proceedings. In the case of an event of default, the holders of the notes are entitled to remedies, including the acceleration of payment of the notes by request of the holders of at least 25% in
aggregate principal amount of the notes, and any action by the trustee to collect payment of principal, interest or premium in arrears.

Prior
to March 15, 2013, the issuers may redeem up to 35% of the aggregate principal amount of the notes at a premium, plus accrued and unpaid interest with net cash proceeds of
certain equity offerings. Prior to March 15, 2014, the issuers may redeem some or all of the notes at a make-whole premium, as set forth in the offering memorandum. After
March 15, 2014, the issuers may redeem some or all of the notes at a premium that will decrease over time until maturity.



Concurrently with the issuance of our senior notes, Niska US and the AECO Partnership entered into new senior secured asset-based
revolving credit facilities, consisting of a U.S. revolving credit facility and a Canadian revolving credit facility. References in this report to "our new credit facilities" or "our
$400.0 million credit agreement" refer to the credit agreement and credit facilities, respectively, of the AECO Partnership and Niska US. These new revolving credit facilities provide for
revolving loans and letters of credit in an aggregate principal amount of up to $200.0 million for each of the U.S. revolving credit facility and the Canadian revolving credit facility. Subject
to certain conditions, each of the revolving credit facilities may be expanded up to $100.0 million in additional commitments, and the commitments in each facility may be reallocated on terms
and according to procedures to be determined. Loans under the U.S. revolving facility will be denominated in U.S. dollars and loans under the Canadian revolving facility may be denominated, at our
option, in either U.S. or Canadian dollars. Royal Bank of Canada is acting as administrative agent and collateral agent for the revolving credit facilities. Each revolving credit facility has a
four-year maturity.

Borrowings
under our revolving credit facilities are limited to a borrowing base calculated as the sum of specified percentages of eligible cash equivalents, eligible accounts
receivable, the net liquidating value of hedge positions in broker accounts, eligible inventory, issued but unused letters of credit, and certain fixed assets minus the amount of any reserves and
other priority claims. Borrowings will bear interest at a floating rate, which (1) in the case of U.S. dollar loans can be either LIBOR plus an applicable margin or, at our option, a base rate
plus an applicable margin, and (2) in the case of Canadian dollar loans can be either the bankers' acceptance rate plus an applicable margin or, at our option, a prime rate plus an applicable
margin. The credit agreement provides that we may borrow only up to the lesser of the level of our then current borrowing base and our committed maximum borrowing capacity, which is currently
$400.0 million. Our borrowing base was $469.9 million as of June 1, 2011.

Our
obligations under our $400.0 million credit agreement will be guaranteed by us and all of our direct and indirect wholly owned subsidiaries (subject to certain exceptions) and
secured by a lien on substantially all of our and our direct and indirect subsidiaries' current and fixed assets (subject to certain exceptions). Certain fixed assets will only be required to be part
of the collateral to the extent such fixed assets are included in the borrowing base under the respective revolving credit facility. The aggregate borrowing base under both revolving credit facilities
includes $150.0 million (the "PP&E Amount") due to a first-priority lien on fixed assets granted to the lenders. The PP&E Amount will be reduced on a dollar-for-dollar
basis upon the release of fixed assets having a value in excess of $50.0 million from such liens.

Table of Contents

The
following fees are applicable under each revolving credit facility: (1) an unused line fee of 0.75% per annum, based on the unused portion of the respective revolving credit
facility; (2) a letter of credit participation fee on the aggregate stated amount of each letter of credit equal to the applicable margin for LIBOR loans or bankers' acceptance loans, as
applicable; and (3) certain other customary fees and expenses of the lenders and agents. We will be required to make prepayments under our revolving credit facilities at any time when, and to
the extent that, the aggregate amount of the outstanding loans and letters of credit under such revolving credit facility exceeds the lesser of the aggregate amount of commitments in respect of such
revolving credit facility and the applicable borrowing base.

Our
$400.0 million credit agreement contains customary covenants, including, but not limited to, restrictions on our and our subsidiaries' ability to merge and consolidate with
other companies, incur indebtedness, grant liens or security interests on assets subject to security interests under the credit agreement, make acquisitions, loans, advances or investments, pay
distributions, sell or otherwise transfer assets, optionally prepay or modify terms of any subordinated indebtedness or enter into transactions with affiliates. Our new revolving credit facilities
require the maintenance of a fixed charge coverage ratio of 1.1 to 1.0 at the end of each fiscal quarter when excess availability under both revolving credit facilities is less than 15% of the
aggregate amount of availability under both revolving credit facilities. Such fixed charge coverage ratio will be tested at the end of each quarter until such time as average excess availability
exceeds 15% for thirty consecutive days.

Our
$400.0 million credit agreement contains limitations on our ability to pay distributions in respect of, repurchase or pay dividends on our membership interests (or other
capital stock) or make other restricted payments. These limitations are substantially similar to those contained in the indenture governing our senior notes described above, except that the credit
agreement does not contain a general basket of $75.0 million of restricted payments. As of March 31, 2011, our $400.0 million credit agreement would have permitted us to
distribute approximately $75 million.

Our
$400.0 million credit agreement provides that, upon the occurrence of certain events of default, our obligations thereunder may be accelerated and the lending commitments
terminated. Such events of default include payment defaults to the lenders, material inaccuracies of representations and warranties, covenant defaults, cross-defaults to other material indebtedness,
including our senior notes, voluntary and involuntary bankruptcy proceedings, material money judgments, material events relating to pension plans, certain change of control events and other customary
events of default.

As
of June 1, 2011, we had no borrowings outstanding under our revolving credit facilities and had $54.0 million in letters of credit issued. We and our subsidiaries were
in compliance with all covenant requirements under our credit facilities at June 1, 2011.

obligations consist of forward physical and financial commitments related to purchases of natural gas. As we economically hedge substantially all
of our natural gas purchases, there are forward sales that offset these commitments that are not included in the above table. As at March 31, 2011, forward physical and financial sales for all
future periods totaled $3,691 million.




In accordance with GAAP, there is no carrying value recorded for a credit facility until we borrow from the facility. In the future we
may use off-balance sheet arrangements such as undrawn credit facility commitments, including letters of credit, to finance portions of our capital and operating needs. See
"Contractual Obligations" for more information.

On
January 1, 2010, Wild Goose entered into an operating lease for compression and other equipment related to the development of an expansion project. The primary term of the
operating lease is five years, although there is an early purchase option which Wild Goose can exercise after three years. At the end of either term, Wild Goose can purchase the leased equipment from
the operating lease counterparty at fair market value. The table above indicates all payments required under the primary term of the operating lease.

Critical Accounting Estimates and Policies

The historical financial statements included elsewhere in this document have been prepared in accordance with GAAP. GAAP represents a
comprehensive set of accounting and disclosure rules and requirements, the application of which requires management's judgments and estimates including, in certain circumstances, choices between
acceptable GAAP alternatives. The following is a discussion of our most critical accounting estimates, judgments and uncertainties that are inherent in the application of GAAP, including revenue
recognition, the valuation of risk management assets and liabilities, inventory and goodwill. These estimates affect, among other items, valuing identified intangible assets, evaluating impairments of
long-lived assets, depreciation of cushion gas, establishing estimated useful lives for long-lived assets, estimating revenues and expense accruals, assessing income tax
expense and the requirement for a valuation allowance against the deferred income tax asset and valuing asset retirement obligations.

Table of Contents



Our assessment of each of the four revenue recognition criteria as they relate to our revenue producing activities is as follows:

Persuasive evidence of an arrangement exists.Our customary practices are to enter into a written contract, executed by both the
customer and us.

Delivery.Delivery is deemed to have occurred at the time the natural gas is delivered and title is transferred, or in the case of
fee-based arrangements, when the services are rendered. To the extent that we retain our inventory, delivery occurs when the inventory is subsequently sold and title is transferred to the
third party purchaser.

The fee is fixed or determinable.We negotiate the fee for our services at the outset of our fee-based arrangements. In these
arrangements, the fees are nonrefundable. The fees are generally due on the 25th of the month following the delivery or services rendered. For other arrangements, the amount of revenue is
determinable when the sale of the applicable product has been completed upon delivery and transfer of title.

Collectability is reasonably assured.Collectability is evaluated on a customer-by-customer basis. New and existing customers
are subject to a credit review process, which evaluates the customers' financial position (e.g. cash position and credit rating) and ability to pay. If collectability is not considered
reasonably assured at the outset of an arrangement in accordance with our credit review process, revenue is recognized when the fee is collected.

Revenue
from our LTF contracts consists of monthly storage fees and fuel and commodity charges for injections and withdrawals. LTF contract revenue is accrued on a monthly basis in
accordance with the terms of the customer contracts. Customer charges for injections and withdrawals are recorded in the month of injection or withdrawal.

STF
contract revenue consists of fees for injections and withdrawals, which include fuel and commodity charges. One half of the fees are earned at the time of injection by the customer
and one-half of the fees are charged at the time of withdrawal by the customer.

Energy
trading contracts resulting in the delivery of a commodity where we are the principal in the transaction are recorded as proprietary optimization revenues or purchases at the time
of physical delivery. Realized and unrealized gains and losses on financial energy trading contracts are included in proprietary optimization revenue. See Note 13 to our consolidated financial
statements included elsewhere in this document.



Niska Partners uses natural gas derivatives and other financial instruments to manage its exposure to changes in natural gas prices,
foreign exchange, and interest rates. These financial assets and liabilities, which are recorded at fair value on a recurring basis, are included into one of three categories based on a fair value
hierarchy.

The
fair value of our derivative and risk management contracts are recorded as a component of risk management assets and liabilities, which are classified as current or
non-current assets or liabilities based upon the anticipated settlement date of the contracts. The determination of the fair value of these derivative and physical contracts reflects the
price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In the determination of fair value, we
consider various factors, including closing foreign exchange and over-the-counter quotations, time value and volatility factors underlying the contracts. Although the fair
value of our risk management assets and liabilities may fluctuate, such fluctuations will always be offset

66

Table of Contents

by
equivalent changes in the value of our physical inventory and purchases. Our policy is for our inventory and purchases always to be economically hedged, within small tolerances permitted under our
risk management policies, so we are not exposed economically to the risk of fluctuating commodity prices. We do not speculate on changes in the price of the commodity, rather we only lock in margins
when they are available in the market. See "BusinessOur OperationsProprietary Optimization." For further analysis regarding our sensitivities to fluctuations in the price of
natural gas, see "Management's Discussion and Analysis of Financial Condition and Results of OperationQuantitative and Qualitative Disclosures about Market RisksCommodity
Price Risks."



Our inventory is natural gas injected into storage and held for resale. Long-term inventory represents
non-cycling working gas. We inject non-cycling working gas on a temporary basis to increase pressure within the reservoirs to allow us to market higher cycling contracts or
previously un-saleable gas from an underutilized reservoir that can be sold into the market when we add mechanical compression to the reservoir. This mechanical compression will allow
access to natural gas that was previously required to maintain pressure within the reservoir. Inventory is valued at the lower of average cost and market.



Certain volumes of gas defined as Cushion Gas are required for maintaining a minimum field pressure. Cushion Gas is considered a
component of the facility and as such is not amortized because it is expected to ultimately be recovered and sold. Cushion Gas is monitored to ensure that it provides effective pressure support. In
the event that gas moves to another area of the reservoir where it does not provide effective pressure support, charges against Cushion Gas are included in depreciation in an amount equal to the
estimated volumes that have migrated.



We evaluate whether events or circumstances have occurred that indicate that long-lived assets may not be recoverable or
that the remaining useful life may warrant revision. When such events or circumstances are present, we assess the recoverability of long-lived assets by determining whether the carrying
value will be recovered through the expected undiscounted future cash flows. In the event that the sum of the expected future cash flows resulting from the use of the asset is less than the carrying
value of the asset, an impairment loss equal to the excess of the asset's carrying value over its fair value is recorded.



We account for business acquisitions using the purchase method of accounting and accordingly the assets and liabilities of the acquired
entities are recorded at their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired is attributed to goodwill.

Goodwill
is not amortized and is re-evaluated on an annual basis or more frequently if events or changes in circumstances indicate that the asset might be impaired.

Goodwill
is tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its
carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, sale or disposition of a
significant portion of the business or other factors. The performance of the test involves a two-step process. The first step of the impairment test involves comparing the fair values of
the applicable reporting units with their aggregate

67

Table of Contents

carrying
values, including goodwill. If the carrying amount exceeds the fair value of the reporting unit, we perform the second step of the goodwill impairment test to determine the amount of
impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit's goodwill with the carrying value of that goodwill.

Determining
the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions. These assumptions are dependent on several
subjective factors including the timing of future cash flows and future growth rates. The fair value of our reporting units is determined based on a weighting of multiples of potential earnings
approaches which is classified under Level 3 fair value measurement under FASB ASC 820. The multiples of earnings approach estimates fair value by applying multiples of potential earnings,
working gas capacity, and cyclability of similar entities. Results using the multiples of potential earnings and the multiples of gas capacity and cyclability are given equal weighting when
determining the valuation using this approach. The future operating projections are based on consideration of past performance and the projections and assumptions used in our current operating plans
and adjusted for market participant assumptions as appropriate. We then assign a weighting to the multiple or earnings to derive the fair value of the reporting unit.

These
types of analyses contain uncertainties because they require management to make assumptions and apply judgment to estimate economic factors and the profitability of future business
strategies and
industry conditions. A reduction in volatility and the narrowing of seasonal natural gas storage spreads in the last six months of the fiscal year ended March 31, 2011 compressed
short-term firm and realized optimization margins compared to those experienced in the prior fiscal year. If narrow seasonal spreads and low volatility persist for an extended period of
time, these conditions could impact the Company's intermediate and long-term forecast of revenues and profitability and, therefore, valuations of goodwill.

Intangible
assets representing customer contracts are amortized over their useful lives. These assets are reviewed for impairment as impairment indicators arise. When such events or
circumstances are present, the recoverability of long-lived assets is assessed by determining whether the carrying value will be recovered through the expected undiscounted future cash
flows. In the event that the sum of the expected future cash flows resulting from the use of the asset is less than the carrying value of the asset, an impairment loss equal to the excess of the
asset's carrying value over its fair value is recorded. Pipeline rights of way are formal agreements granting rights of way into perpetuity and are not subject to amortization but are subject to an
annual impairment test.



We are not taxable entities. Income taxes on their income are the responsibility of the individual partners and have accordingly not
been recorded in the consolidated financial statements. Niska Partners has corporate subsidiaries, which are taxable corporations subject to Canadian federal and provincial income taxes, which are
included in the consolidated financial statements.

Income
taxes on the Canadian corporate subsidiaries are provided based on the asset and liability method, which results in deferred income tax assets and liabilities arising from
temporary differences. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or
deductible amounts in future years. This method requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period in which the rate change was
enacted. The asset and liability method also requires that deferred income tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized.

Recent Accounting Pronouncements

Fair
Value Measurement (ASC 810-10)

Effective
April 1, 2010, we are required to disclose the fair value information of financial instruments at each interim reporting period. The
disclosures include the relevant carrying value as well as the methods and significant assumptions used to estimate the fair value, in addition to transfers into and out of the three levels of the
fair value hierarchy (described as Level 1, Level 2 and Level 3), as well as additional details about movements within Level 3. The new standard clarifies the level of
disaggregation required and the inputs and valuation techniques used to measure fair value. The adoption of this standard did not impact how we account for balances recorded at fair value.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risks.

The term "market risks" refers to the risk of loss arising from changes in commodity prices, currency exchange rates, interest rates,
counterparty credit and liquidity. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking
information provides indicators of how we view and manage our ongoing market risk exposures.



To mitigate exposure to changes in commodity prices, we enter into purchases and sales of natural gas inventory and concurrently match
the volumes in these transactions with offsetting forward contracts or other hedging transactions.

Derivative
contracts used to manage market risk generally consist of the following:



In
order to manage our exposure to commodity price fluctuations, our policy is to promptly enter into a forward sale contract or other hedging transaction for every proprietary purchase
contract we enter into. Therefore, inventory purchases are matched with forward sales or are otherwise economically hedged so that there are no speculative positions beyond the minimal operational
tolerances specified in our risk policy.

At
March 31, 2011, 32.8 Bcf of natural gas inventory was economically hedged, representing 99.4% of our total current inventory. However, because inventory is recorded at the
lower of cost or market, not fair value, if the price of natural gas increased by $1.00 per Mcf the value of that inventory would increase by $32.8 million, but the fair value or
mark-to-market value of our hedges would decrease by only $32.6 million, due to 0.6% (0.2 Bcf) of that inventory that was not economically hedged. Conversely, if the
price of natural gas declined by $1.00 per Mcf, the value of that inventory would

69

---



Table of Contents

decrease
by $32.4 million while the fair value of our hedges would increase by only $32.2 million, due to the non-economically hedged position. Long-term
inventory and fuel gas
used for operating our facilities are not offset. Total volumes of long-term inventory and fuel gas at March 31, 2011 are 3.4 Bcf and 0.0 Bcf, respectively.

Although
the intent of our risk-management strategy is to protect our margins and manage our liquidity risk on related margin deposit requirements, we do not qualify any of
our derivatives for hedge accounting. Changes in the fair values of these derivatives receive mark-to-market treatment in current earnings and result in greater potential for
earnings volatility. This accounting treatment is discussed further under Note 2 of the Notes to our Consolidated Financial Statements and "Critical Accounting Estimates and
Policies."



Our cash flow relating to our Canadian operations is reported in the U.S. dollar equivalent of such amounts measured in Canadian
dollars. Monetary assets and liabilities of our Canadian subsidiaries are translated to U.S. dollars using the applicable exchange rate as of the end of a reporting period. Revenues, expenses and cash
flow are translated using the average exchange rate during the reporting period.

Because
a portion of our Canadian business is conducted in Canadian dollars, we use certain financial instruments to minimize the risks of changes in the exchange rate. These instruments
include forward swaps or spot swaps buying or selling U.S. dollars. Options may also be used in the future. All of the financial instruments utilized are placed with large brokers and financial
institutions.

At
March 31, 2011, we had forward currency exchange contracts for a notional value of $142.8 million. The value of the forward currency contracts at March 31, 2011
and 2010 was a liability of $6.3 million, and a liability of $4.1 million, respectively, and is recorded in derivative assets and derivative liabilities on the consolidated balance
sheets. These contracts expire on various dates between April 1, 2011 and August 1, 2014 and are for the exchange of $145.9 million Canadian dollars into $142.8 million
U.S. dollars at a weighted average rate of 1.022 Canadian dollars to 1.00 dollar.



We are exposed to interest rate risk due to variable interest rates under our $400.0 million credit agreement. All such
borrowings under our credit facilities bear interest at variable rates. As of March 31, 2011, we had no borrowings outstanding under our revolving credit
facilities. The credit facilities would currently provide an interest rate on borrowings of 5.0% (assumes LIBOR plus 350 basis points, where LIBOR is approximately 1.50%). In the future, we may borrow
under fixed rate and variable rate debt instruments that also give rise to interest rate risk. Changes in economic conditions could result in higher interest rates, thereby increasing our interest
expense and reducing our funds available for capital investment, operations or distributions to our unitholders.



Counterparty credit risk is the risk of financial loss if a customer fails to perform its contractual obligations. We engage in
transactions for the purchase and sale of products and services with major companies in the energy industry and with industrial, commercial, residential and municipal energy consumers. Credit risk
associated with trade accounts receivable is mitigated by the high percentage of investment grade customers, collateral support of receivables and our ability to take ownership of customer-owned
natural gas stored in its facilities in the event of non-payment.

Margin
deposits, or letters of credit in lieu of deposits, are required on derivative instruments utilized to manage our counterparty credit risk. As commodity prices increase or
decrease, the fair

70

---



Table of Contents

value
of our derivative instruments changes thereby increasing or decreasing our margin deposit requirements. Rising commodity prices or an expectation of rising prices could increase the cash needed
to manage our commodity price exposure and thereby increase our liquidity requirements, limit amounts available to us through borrowing and reduce the volume of natural gas we may purchase. Exchange
traded futures and options have minimal credit exposure as the exchanges guarantee every contract will be margined on a daily basis. In the event of any default, our account on the exchange would be
absorbed by other clearing members. Because every member posts an initial margin, the exchange can protect the exchange members if or when a clearing member defaults.



Liquidity risk is the risk that we will not be able to meet our financial obligations as they become due. Our approach to managing
liquidity risk is to contract a substantial part of our facilities to generate constant cash flow and to ensure that they always have sufficient cash and credit facilities to meet their obligations
when due, under both normal and stressed conditions, without incurring unacceptable losses or damage to reputation.



The fair values of the derivative instruments are based on quoted market prices obtained from NYMEX or ICE and from various sources
such as independent reporting services, industry publications and brokers. These quotes are compared to the contract price of the instrument, which approximates the gain or loss that would have been
realized if the contracts had been closed out at a specified time. We utilize observable market data when available, or models that utilize observable market data when determining fair value.

Risk Management Policy and Practices

We have in place risk management practices that are intended to quantify and manage risks facing our business. These risks include, but
are not limited to, market, credit, foreign exchange, operational, and liquidity risks. Our hedging practices mitigate our exposure to commodity price and foreign exchange risks. Strict open position
limits are enforced, and physical inventory is offset with forward hedges. Our counterparty strategy ensures we have a strong mix of quality customers. We have models in place to monitor and manage
operational and liquidity risks.

The
Risk Management Committee, or RMC, is comprised of members of our management team. The RMC provides oversight of our commercial activities. The committee reviews the adequacy of
controls to ensure compliance with the risk policy. Our RMC meets weekly to review and respond to risks facing our business. The RMC analyzes positions and exposures and provides daily and weekly
reporting to facilitate understanding of these exposures. The RMC assesses and manages the potential for loss in our positions through these reports. If limits are exceeded, the RMC is informed and
appropriate action is taken to review and remedy. The RMC is independent of the Commercial and Marketing groups and reports through our chief financial officer.

Optimization
activities can only be executed by employees authorized to transact under the risk policy. All commercial personnel are annually required to read and certify that they will
adhere to the principles purported within the policy. Each person authorized to make transactions is subject to internal volume limits. Counterparties are subject to credit limits as approved by our
credit department.

Our
commercial and risk functions operate independently to ensure proper segregation of duties. Critical deal information for every transaction is entered into our deal capture systems
and confirmed with counterparties.

Despite the policies, procedures and controls described above, there can be no assurance that our risk management systems will prevent losses that would
negatively affect our business, results of operations, cash flows and financial condition. See "Risk FactorsRisks Inherent in Our BusinessOur risk management policies cannot
eliminate all commodity price risk." In addition, any non-compliance with our risk management policies could result in significant financial losses.

Item 8.    Financial Statements and Supplementary Data.

The Report of Independent Registered Public Accounting Firm, Consolidated Financial Statements and supplementary financial data
required for this Item are set forth on pages F-4 through F-10 of this Annual Report on Form 10-K and are incorporated herein by reference.

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

On February 4, 2011 we changed our principal independent accountant from KPMG LLP, the Canadian member firm affiliated
with KPMG International ("KPMG Canada"), to KPMG LLP, the United States member firm affiliated with KPMG International ("KPMG USA"). This change constituted the dismissal of KPMG Canada and the
engagement of KPMG USA. The decision to change accountants was approved by the Audit Committee of our Board of Directors.

During
our two most recent fiscal years, KPMG Canada's reports on our financial statements and its predecessors did not contain an adverse opinion or disclaimer of opinion, and were not
qualified or modified as to uncertainty, audit scope or accounting principles.

During
our and our predecessors' two most recent fiscal years or the subsequent period through February 4, 2011, we and KPMG Canada have not had any disagreements on any matter of
accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to the satisfaction of KPMG Canada, would have caused KPMG Canada to make
reference to the matter in its reports on our financial statements; and (ii) there were no reportable events as the term is described in Item 304(a)(1)(iv) of
Regulation S-K.

During
the most recent years ended March 31, 2010 and 2009 and any subsequent interim period through February 4, 2011 we did not consult with KPMG USA, the newly engaged
accountant, regarding any matter described in Item 304(a)(2) of Regulation SK, including any issue related to our financial statements, subject of a disagreement, any reportable event or
the type of audit opinion that might be rendered for us.

Item 9A.    Controls and Procedures.



Our principal executive officer (CEO) and principal financial officer (CFO) undertook an evaluation of our disclosure controls and
procedures as of the end of the period covered by this report. The CEO and CFO have concluded that our controls and procedures were effective as of March 31, 2011. For purposes of this section,
the term "disclosure controls and procedures" means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that
it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in SEC's rules and forms. Disclosure controls and procedures include,
without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and
communicated to the issuer's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding
required disclosure.

PART III

Item 10.    Directors, Executive Officers and Corporate Governance.



Our manager has sole responsibility for conducting our business and for managing our operations. Pursuant to our Operating Agreement,
our manager has delegated the power to conduct our business and manage our operations to our board. Our manager may revoke this delegation and resume control of our business at any time. Our manager
and our board are not elected by our unitholders and will not be subject to re-election on a regular basis in the future.
As long as the delegation of authority is in effect, our manager will appoint all members to our board. Unitholders will not be entitled to elect our directors or directly or indirectly participate in
our management or operation. Our Operating Agreement provides that our manager must act in "good faith" when making decisions on our behalf.

Whenever
our manager makes a determination or takes or declines to take an action in its individual, rather than representative, capacity or in its sole discretion, it is entitled to
make such determination or to take or decline to take such other action free of any fiduciary duty or obligation whatsoever to us or any member, and our manager is not required to act in good faith or
pursuant to any other standard imposed by our Operating Agreement or under the Delaware Act or any other law. Examples include the exercise of its limited call rights, its voting rights with respect
to the units it owns, its registration rights and its determination whether or not to consent to any merger or consolidation. Actions of our manager which are made in its individual capacity or in its
sole discretion will be made by a majority of the owners of our manager.

In
selecting and appointing directors to our board, our manager does not apply a formal diversity policy or set of guidelines. However, when appointing new directors, our manager
considers each individual director's qualifications, skills, business experience and capacity to serve as a director, as described below for each director, and the diversity of these attributes for
the board as a whole.

Directors and Executive Officers

Our directors hold office until the earlier of their death, resignation, retirement, disqualification or removal by the member of our
manager. Our executive officers serve at the discretion of our board.

member
of GATX Corp., a Chicago-based transportation services firm, where she is Chair of the Compensation Committee and was formerly Lead Director.

As
a result of her service to Sunoco Logistics, Ms. Fretz gained extensive experience in overseeing the strategy, operations, and governance of major public companies.
Ms. Fretz was also selected to serve as a director of our board due to her valuable knowledge of the energy industry. Ms. Fretz's experience has also given her knowledge of the unique
issues related to operating publicly-traded limited partnerships, which are similar to us. We believe this background and skill set makes Ms. Fretz well-suited to serve as a member
of our board.

James G. JacksonMr. Jackson has been the Chief Financial Officer of BreitBurn GP, LLC, the general partner of BreitBurn Energy
Partners L.P.(NASDAQ: BBEP) since July 2006 and an Executive Vice President since October 2007. Before joining BreitBurn, Mr. Jackson served as Managing Director of Merrill
Lynch & Co.'s Global Markets and Investment Banking Group. Mr. Jackson joined Merrill Lynch in 1992 and was elected Managing Director in 2001. Previously, Mr. Jackson was a
Financial Analyst with Morgan Stanley & Co. from 1986 to 1989 and was an Associate in the Mergers and Acquisitions Group of the Long-Term Credit Bank of Japan from 1989 to
1990. Mr. Jackson obtained a B.S. in Business Administration from Georgetown University and an M.B.A. from the Stanford Graduate School of Business.

Mr. Jackson's
knowledge and experience with BreitBurn Energy Partners L.P. and BreitBurn GP, LLC, has provided him with valuable experience and familiarity
with master limited partnerships and, more specifically, the natural gas business. These skills coupled with his broad investment banking acumen and acquisition and financing experience brings
additional depth to our Board's collective expertise, and therefore makes Mr. Jackson a key addition to our Board of Directors.

E. Bartow JonesMr. Jones is a member of our board, the board of directors of our manager and the board of supervisors of Niska Holdings, which
is our parent. Mr. Jones is currently a Managing Director of Riverstone Holdings LLC where he served as a Principal from 2007 to 2010. Mr. Jones has been with Riverstone since
2001. Mr. Jones currently serves on the boards of directors of Foresight Reserves, L.P., or Foresight, and Targe Energy, LLC, or Targe, and he previously served on the boards of
directors of Buckeye and Mainline Management.

Mr. Jones
has worked closely with us since our inception. Mr. Jones's experience in evaluating the financial performance and operations of companies in our industry, as
well as his leadership skills and business acumen, provide him with the necessary skills to serve as a member of our board. In addition, Mr. Jones's work with Foresight, Buckeye, Targe and
MainLine Management has given him both an understanding of the broader energy business and of the unique issues related to operating publicly-traded limited partnerships, which are similar to us.

Stephen C. MutherMr. Muther served as President of the general partner of Buckeye Partners, L.P. ("BPL") and the general
partner of Buckeye GP Holdings L.P. ("BGH") from October 25, 2007 until his retirement in February 2009. BPL is a publicly-traded master limited partnership that is principally
engaged in the transportation, terminalling, marketing and storage of refined petroleum products for major integrated oil companies, large refined products marketing companies and major end users of
petroleum products. BGH is a publicly-traded master limited partnership that owns 100% of the general partner of BPL. From February 2007 to November 2007, Mr. Muther served as Executive Vice
President, Administration and Legal Affairs of the general partners of BPL and BGH, and from May 1990 to February 2007, Mr. Muther held the position of Senior Vice President, Administration,
General Counsel and Secretary of the general partner of BPL. Prior to joining Buckeye, Mr. Muther was Associate Litigation and Antitrust Counsel for General Electric Company from July 1984 to
May 1990. Mr. Muther was an associate attorney with

Debevoise &
Plimpton in New York City from February 1975 to June 1984. Mr. Muther graduated from Princeton University in 1971 and from the University of Virginia School of Law in 1974.

As
a result of his service to BPL and BGH, Mr. Muther gained extensive experience in overseeing the strategy, operations, and governance of major public companies.
Mr. Muther was also selected to serve as a director of our board due to his valuable legal expertise and his knowledge of the energy industry. Mr. Muther's experience has also given him

well-suited to serve as a member of our board.

George A. O'BrienMr. O'Brien is a member of our board and the board of directors of our manager. Mr. O'Brien has served as an
independent director of Magellan GP, LLC, and general partner of Magellan Midstream Partners, L.P., or Magellan, a publicly-traded company that is engaged in the transportation,
storage and distribution of refined petroleum products, from December 2003 until November 2009. Mr. O'Brien was President and CEO of Pacific Lumber Company from August 2006 until July 2008.
From 1988 until 2005, he worked for International Paper where he served as Senior Vice President of Forest Products responsible for its forestry, wood products, minerals and specialty chemicals
businesses. Other responsibilities during his tenure at International Paper included corporate development, CFO of its New Zealand subsidiary, CEO of the New Zealand pulp, paper and tissue businesses
and Vice President of Corporate Development. In January 2007, Pacific Lumber Company filed for voluntary reorganization under Chapter 11 of the United States Bankruptcy Code. Pacific Lumber
successfully emerged from Chapter 11 in July, 2008. Mr. O'Brien has an agreement with Riverstone, pursuant to which he has agreed to serve on the boards of Carlyle/Riverstone Funds'
portfolio companies.

As
a result of his service to Magellan and International Paper, Mr. O'Brien gained extensive experience in overseeing the strategy, operations, and governance of major public
companies. Mr. O'Brien was also
selected to serve as a director of our board due to his valuable financial expertise, including extensive experience with capital markets transactions and knowledge of the energy industry.
Mr. O'Brien's experience has also given him knowledge of the unique issues related to operating publicly-traded limited partnerships, which are similar to us. We believe this background and
skill set makes Mr. O'Brien well-suited to serve as a member of our board.

William H. Shea, Jr.Mr. Shea is a member of our board and the board of directors of our manager. Mr. Shea has served as a director and
Chief Executive Officer of Penn Virginia Resource Partners, L.P. since March 2010. Previously, Mr. Shea served as the Chairman of Buckeye GP LLC, the general partner of
Buckeye Partners, L.P., a refined petroleum products pipeline partnership from May 2004 to July 2007, as President and Chief Executive Officer of Buckeye GP LLC from
September 2000 to July 2007 and as President and Chief Operating Officer of Buckeye GP LLC from July 1998 to September 2000. From August 2006 to July 2007, Mr. Shea served
as Chairman of MainLine Management LLC, the general partner of Buckeye GP Holdings, L.P., and as President and Chief Executive Officer of MainLine Management LLC from May
2004 to July 2007. Mr. Shea also serves as a director of Kayne Anderson Energy Total Return Fund, Inc. and Kayne Anderson MLP Investment Company. Mr. Shea has an agreement with
Riverstone, pursuant to which he has agreed to serve on the boards of Carlyle/Riverstone Funds' portfolio companies.

Mr. Shea's
experiences as an executive with both Penn Virginia and Buckeye, energy companies that operate across a broad spectrum of sectors, including coal, natural gas gathering
and processing and refined petroleum products transportation, have given him valuable knowledge about our industry. In addition, Mr. Shea has valuable experience overseeing the strategy and
operations of publicly-traded partnerships, which are similar to us. As a result of this experience and resulting skills set, we believe Mr. Shea is an asset to our board.

Andrew W. WardMr. Ward is a member of our board, the board of directors of our manager and the board of supervisors of Niska Holdings, which
is our parent. Mr. Ward has served as a member of the board of supervisors of Niska Holdings since May 2006. He is currently a Managing Director of Riverstone Holdings LLC where he
served as a Principal from March 2002 to December 2004. Mr. Ward currently serves on the board of directors of Gibson Energy and GEP Midstream and has previously served on the boards of
directors of Buckeye GP LLC, or Buckeye, the general partner of Buckeye Partners, L.P., a refined petroleum products pipeline partnership, and MainLine Management LLC, or
MainLine Management, the general partner of Buckeye GP Holdings L.P.

Mr. Ward
has served as a director since our inception. Mr. Ward's experience in evaluating the financial performance and operations of companies in our industry, combined
with his leadership skills and business acumen, makes him a valuable member of our board. In addition, Mr. Ward's work with Gibson Energy, GEP Midstream, Buckeye and MainLine Management has
given him both an understanding of the midstream sector of the energy business and of the unique issues related to operating publicly-traded limited partnerships, which are similar to us.



Our Board has determined that Deborah M. Fretz, Stephen C. Muther and James G. Jackson are independent directors under the listing
standards of the NYSE. Our Board considered all relevant facts and circumstances and applied the independence guidelines of the NYSE in determining that neither of these directors has any material
relationship with us, our management, our general partner or its affiliates or our subsidiaries.

We
hold regularly scheduled meetings of our independent directors. In accordance with our Corporate Governance Guidelines, Mr. Muther will preside over meetings of our independent
directors.

The
procedure by which any interested party may communicate directly with an independent director is set forth in our Corporate Governance Guidelines, which is available on our website.



Our board has established an audit committee to assist it in its oversight of the integrity of our financial statements and our
compliance with legal and regulatory requirements and corporate policies and controls. Our Audit Committee is comprised of Ms. Fretz, Mr. Muther and Mr. Jackson. Our audit
committee is fully independent as defined in the listing standards of the NYSE. Our audit committee has the sole authority to retain and terminate our independent registered public accounting firm,
approve all auditing services and related fees and the terms thereof, and pre-approve any non-audit services to be rendered by our independent registered public accounting
firm. Our audit committee is also responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm
has unrestricted access to the audit committee.

We
have designated Ms. Fretz, Mr. Muther and Mr. Jackson as audit committee financial experts. Mr. Muther has been appointed the Chairman of the audit
committee.



As a controlled company that is listed on the NYSE, we are not required to have a compensation committee. In order to conform to best
governance practices, however, our board has established a compensation committee to, among other things, oversee the compensation plans described below. The compensation committee establishes and
reviews general policies related to our compensation and benefits. The compensation committee has the responsibility to determine and approve, or make

Table of Contents

recommendations
to the board with respect to, the compensation and benefits of our board and executive officers.

The
Compensation Committee is composed of Mr. O'Brien, Mr. Shea and Ms. Fretz. Ms. Fretz is an independent director (as that term is defined in the applicable
NYSE rules and Rule 10A-3 of the Exchange Act). All members of the compensation committee are non-employee directors (as that term is defined in
Rule 16b-3 of the Exchange Act). None of our executive officers served as a director or member of a compensation committee of another entity that has or has had an executive officer
who served as a member of our board during 2010, 2009 or 2008.



Whenever a conflict arises between our manager or its affiliates, on the one hand, and us or any unaffiliated member, on the other, our
board will resolve that conflict. Our board may establish a conflicts committee to review specific matters that our board refers to it. Our board may, but is not required to, seek the approval of such
resolution from the conflicts committee. The conflicts committee will determine if the resolution of the conflict of interest is fair and reasonable to us. Such a committee would consist of a minimum
of two members, none of whom can be officers or employees of our manager or directors, officers or employees of its affiliates (other than us and our subsidiaries) and each of whom must meet the
independence standards for service on an audit committee established by the NYSE and the SEC. Any matters approved by the conflicts committee will be conclusively deemed to be fair and reasonable to
us, approved by all of our partners, and not a breach by our manager of any duties it may owe us or our unitholders.

If
our board does not seek approval from the conflicts committee, and the board determines that the resolution or course of action taken with respect to the conflict of interest is
either (1) on terms no less favorable to us than those generally being provided to or available from unrelated third parties or (2) fair and reasonable to us, taking into account the
totality of the relationships between the parties involved, including other transactions that may be particularly favorable or advantageous to us, then it will be presumed that, in making its
decision, our board acted in good faith, and in any proceeding brought by or on behalf of us or any member, the person bringing or prosecuting such proceeding will have the burden of overcoming such
presumption.

Reimbursement of Expenses of Our Manager

Our manager does not receive any management fee or other compensation for providing management services to us. Our manager will be
reimbursed for any expenses incurred on our behalf. There is no limit on the amount of expenses for which our manager may be reimbursed.

In
connection with the earlier acquisition of our assets from EnCana Corporation on May 12, 2006, our predecessor agreed to pay Carlyle/Riverstone an annual management fee of
$1.0 million, plus the reimbursement of certain costs and expenses for its services. We are no longer subject to this obligation to Carlyle/Riverstone, as it remained with Holdco upon the
formation of Niska Gas Storage Partners LLC.

Code of Ethics

We have adopted a Code of Business Conduct and Ethics that applies to all of our officers, directors and employees.

Available
on our website at http://www.niskapartners.com are copies of our Audit Committee Charter, our Compensation Committee Charter, our Code of Business Conduct and Ethics and our
Corporate Governance Guidelines, all of which also will be provided to unitholders without charge

their written request to Niska Gas Storage Partners LLC, 1001 Fannin Street, Suite 2500, Houston, TX 77002, Attention: General Counsel.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act requires our officers and directors, and persons who own more than ten percent of a
registered class of our equity securities, to file reports of ownership and changes of ownership on Forms 3, 4 and 5 with the Securities and Exchange Commission. Officers, directors and
greater-than-ten-percent shareowners are required by regulations promulgated by the Securities and Exchange Commission to furnish us with copies of all
Forms 3, 4 and 5 they file.

Based
solely upon a review of Forms 3 and 4 and amendments thereto furnished to us during fiscal 2011 and upon a review of Forms 5 and amendments thereto furnished to us
with respect to fiscal 2011, or upon written representations received by us from certain reporting persons that no Forms 5 were required for those persons, we believe that no director,
executive officer or greater-than-ten-percent shareholder failed to file on a timely basis the reports required by Section 16(a) of the Exchange Act during,
or with respect to, fiscal 2011, except that through inadvertence, the Forms 4 reporting one grant of units to each of Ms. Fretz and Mr. Muther were not timely filed. We have
since rectified this process.

Significant Differences in Corporate Governance Standards

Because Holdco controls more than 50% of the voting power for the election of our directors, we are a controlled company within the
meaning of NYSE rules, which exempt controlled companies from the following corporate governance requirements:



For
so long as we remain a controlled company, we are not required to have a majority of independent directors or nominating, corporate governance or compensation committees.
Accordingly, our unitholders may not have the same protections afforded to shareholders of companies that are subject to all of the NYSE corporate governance requirements.

In reliance on these exemptions, our Board is not comprised of a majority of independent directors, nor do we maintain a nominating/corporate governance
committee.

Directors, Executive Officers and Corporate GovernanceDirectors and Executive Officers: Actions Taken Following the Fiscal Year Ended March 31, 2011

On June 8, 2011, Mr. Pope informed our board that he will be resigning as our President and Chief Executive Officer as
well as all other positions with the subsidiaries and related entities of Niska Gas Storage Partners LLC,, effective July 1, 2011. However, we expect Mr. Pope to remain a member
of our board following his resignation as our President and Chief Executive Officer. As a member of our board, Mr. Pope will be entitled to the same compensation as our directors who are not
officers, employees or paid consultants and advisors of our manager or its affiliates.

Our
board has appointed Mr. Dupéré as interim Chief Executive Officer, effective July 1, 2011. Mr. Dupéré
will hold such office until a permanent Chief Executive Officer is appointed or until his earlier removal or resignation. In addition to this interim role,
Mr. Dupéré will continue to act as our Chief Operating Officer. In addition, in connection with Mr. Pope's resignation, our board has elected
Ms. Deborah Fretz
as our interim non-executive Chairman of the Board, effective July 1, 2011.

Item 11.    Executive Compensation.

Compensation Discussion and Analysis

From our inception in 2006 until our IPO, we operated as a private company. During this pre-IPO period, the compensation
committee of the board of supervisors of Niska Predecessor, or the predecessor compensation committee, established the compensation of our named executive officers. Now the manager and our board, as
its delegate, manages our operations and activities and makes decisions on our behalf. Our board has established a compensation committee that, while our board has delegation powers from our manager
to oversee our operations, will determine and set compensation practices, or make recommendations to the full board regarding compensation matters that the board has reserved final authority over, as
applicable. The compensation of each of our executive officers, including David Pope, Simon Dupéré, Vance Powers, Rick Staples, Jason Dubchak, Darin Olson and Paul
Amirault (collectively, the "named executive officers"), for the fiscal year ending March 31, 2011 was determined and implemented solely by our compensation committee.

Historically,
the objectives of our executive compensation program were to:



The
predecessor compensation committee felt that these objectives were best met by providing a mix of cash and equity-based compensation to our executives, and we continue to believe
that this mix of compensation elements provided us with a successful compensation program because it has allowed us to retain key employees and attract a quality team of executives, while motivating
them to provide a high level of performance to us. We expect our compensation committee to seek to satisfy the same objectives; although the committee will make certain adjustments to the types of
compensation provided and performance metrics used in order to more accurately reflect a compensation program appropriate for a publicly-traded entity.

This
section describes the objectives and elements of our compensation program for the fiscal year ended March 31, 2011 for our named executive officers. This section should be
read together with the Compensation Tables that follow, which disclose the compensation awarded to, earned by or paid to

81

Table of Contents

the
named executive officers with respect to the prior fiscal year, as well as for certain elements of compensation paid to the named executive officers for the fiscal years ending on March 31,
2009 and March 31, 2010.



We have not historically utilized an outside compensation consultant or firm to assist in setting our executive compensation programs.
The predecessor board utilized internal human resources staff to compile information regarding the executives' current and past compensation, and to obtain any publicly available compensation
information regarding executive positions at companies that the board determined to be a "peer" company, but did not engage in any benchmarking practices nor did the predecessor board adhere to any
type of formula when setting compensation. Our board, and the compensation committee of our board, holds the authority to engage outside assistance or a compensation consultant firm in setting
executive compensation if it appears at any time that such assistance would be appropriate.

On
September 15, 2010, Cogent Compensation Partners was formally engaged by our Compensation Committee, on behalf of the Board of Directors to review our overall compensation
structure, including short term and long term compensation. The ultimate findings and recommendation of Cogent Compensation Partners was not implemented by the Compensation Committee until
April 1, 2011.

Elements of Compensation.The primary elements of our named executive officers' compensation other than the officer's base salary are a
combination
of cash bonus awards and long-term equity-based compensation awards. For the fiscal year ended March 31, 2011, the compensation for our named executive officers consisted of the
following elements:



Base Salary.The predecessor compensation committee established base salaries for the named executive officers based on various factors,
including
the amounts it considered necessary to attract and retain high quality executives in our industry and the responsibilities of the named executive officers, and were responsible for approving any
significant changes to executive salaries. Salaries for the named executive officers are generally adjusted on an annual basis to remain competitive as compared to the market.

For
the fiscal year ended March 31, 2011, Mr. Pope had an employment agreement with AECO Partnership, our wholly owned subsidiary that employs and is responsible for
providing compensation and benefits for all of our employees and executive officers. The employment agreement provided for a minimum annual base salary of $450,000 (Canadian dollars, which, using the
exchange rate noted within the Summary Compensation Table below, would be approximately $442,620 US dollars). This base salary amount was determined based upon the scope of Mr. Pope's
responsibilities and commensurate with Mr. Pope's position as chief executive officer. The employment agreement stated that Mr. Pope's salary was eligible to be increased above the
minimum at the predecessor compensation committee's discretion. In reviewing Mr. Pope's base salary for the year following March 31, 2009, however, the predecessor compensation committee
determined that the salary set within Mr. Pope's employment agreement continued to be consistent with the duties and the everyday tasks for which he is responsible. On March 29, 2011,
however, Mr. Pope entered into a new employment agreement that became effective on April 1, 2011, and the changes to his base salary and other elements of his compensation that became
effective with that new employment agreement are discussed in greater detail below.

Discretionary Bonus Awards.A significant portion of the compensation of our named executive officers consists of an annual cash bonus.
While base
salaries offer an important retention element by providing a guaranteed income stream to our employees, we hope to incentivize and motivate our employees to strive for both individual and overall
company success by providing a substantial portion of compensation only when performance for the year calls for an additional compensatory award. We feel that our industry has historically relied
heavily on performance-based cash bonuses to compensate executive officers, and we want to compensate our executives in line with our industry trends and practices. For the prior fiscal year, we
accomplished this goal by awarding discretionary bonus awards to our employees, but with respect to bonuses following the end of the prior fiscal year, please see our discussion of the Short Term
Incentive Plan described below.

Historically
the predecessor compensation committee determined the size, timing and allocation of the bonus based on initial recommendations from our chief executive officer. While the
ultimate amount of any cash bonus paid to our named executive officers is now determined at the discretion of our board, the bonuses are originally structured around target amounts for each employee,
as well as individual and company goals. We communicate a target annual bonus amount to our employees as a certain percentage of their base salary at the beginning of their employment, clearly noting
that individual or company performance may significantly impact the relationship of that target annual amount to what is actually paid out in bonuses. Individual performance goals will depend on an
employee's unit or particular function within a unit, while company performance has historically been tied to Adjusted EBITDA. We believe that paying a bonus tied to our Adjusted EBITDA aligns the
interests of our executives and employees with those of our unitholders and motivates them to provide a high level of performance for us. A portion of the bonuses are accrued, but not paid, pending
the results of the fiscal year end audit and subsequent audit adjustments. Thus, while those portions are accrued for the year in which they are earned, they are not paid until the following fiscal
year.

Historically,
we have established a bonus pool for each fiscal year to be allocated among all employees, including the named executive officers. There have been two layers of potential
bonus pools, a bonus pool of 3% of our first $80.0 million of Adjusted EBITDA, and an additional pool of 8% of Adjusted EBITDA over $80.0 million. Following a determination of the amount
of the available bonus pool, a series of meetings occurs prior to the board's final determination of individual amounts owed to employees. The managers or supervisors of various business units first
met with Mr. Pope to discuss the individual performance of employees that have worked directly under such managers. Mr. Pope then compiled this information and met with our predecessor
compensation committee, where he made recommendations regarding the allotment of the bonus pool based on either ranges of amounts or a specific amount he believed are appropriate for the year. The
predecessor compensation committee then met with our board to pass on its recommendations, which may or may not have been in line with the recommendations of Mr. Pope, as the predecessor
compensation committee felt appropriate. The board then made the final determination of specific amounts due to each employee, including our named executive officers. We anticipate that the same
process will continue on a going forward basis,
although we will substitute our compensation committee for our predecessor compensation committee. Mr. Pope also receives his bonus from the same bonus pool as all other employees, thus by
recommending the allotment of the bonus pool for other employees, Mr. Pope indirectly will have inferred the amount of the bonus pool that could potentially be reserved for himself; however,
our compensation committee, and then our board, will ultimately make all determinations of Mr. Pope's annual cash bonus, if any. The board's determination regarding any individual award may be
based solely on the targets and performance measures that have been used as guidelines for that year, or it may take into consideration extraordinary circumstances or past awards of compensation to
the individual.

Niska Predecessor Class B and Class C Units.In 2006, Niska Predecessor issued Class B units to some of our employees,
including
the named executive officers then employed by us, and Class C units to Mr. Pope pursuant to the terms of his employment agreement and Niska Predecessor's partnership agreements. The
Class B and Class C units represented profits interest in Niska Holdings, and entitle the holders to share in distributions by Niska Holdings once the Class A units in Niska
Predecessor have received distributions equal to their contributed capital plus an 8% rate of return. As of March 31, 2011, the risk of forfeiture had lapsed on all of the Class B and
Class C units upon the completion of the time limitations or the achievement of the performance conditions associated with the units as applicable and certain of our named executive officers
continue to hold these vested units and may receive certain profits interests with respect to these awards. No further grant of the Class B or Class C units, however, occurred during the
prior fiscal year or will occur in the future.

Following
the end of the fiscal year ending March 31, 2011, we also adopted a cash-based long term phantom unit plan for our employees and certain directors that is
described below, the Phantom Unit Performance Plan ("PUPP").

Health and Welfare Benefits.All of our regular full-time employees, including our named executive officers, receive certain health and
welfare benefits. The benefits include a health and dental
plan, a short- and long-term disability plan, basic and optional life insurance, and basic and optional accidental death and dismemberment insurance coverage (with the exception of
Mr. Powers). Pursuant to his employment agreement that was effective during the fiscal year ended March 31, 2011, as well his new employment agreement, Mr. Pope is entitled to
receive an annual allowance of $6,000 in order to cover additional health care expenses not directly provided or paid for by us. We also own a life insurance policy on the life of Mr. Pope,
where we are both the owner and beneficiary. We make payments on Mr. Pope's behalf for a Critical Illness policy that was previously established by Mr. Pope's prior employer and
continued by us. Mr. Powers receives health and dental benefits only, which are funded by us.

Retirement and Pension Benefits.Our registered retirement savings plan, or RRSP Plan/Non-Registered Employee Savings Plan, provides
Canadian resident employees with an opportunity to participate in a retirement savings plan. This type of retirement plan is a Canadian retirement plan with features similar to a 401(k) plan or an
individual retirement account administered in the United States. Our employees, including our named executive officers (other than Mr. Powers), are allowed to contribute their own funds, and we
will provide certain matching contributions as well as discretionary contributions from us on their behalf from time to time. Mr. Pope's employment agreement states that he will receive an
annual contribution from us of 8% of his annual base salary, and in the event that Mr. Pope contributes 5% to 25% of his own compensation, a corporate match of up to 5% annually.
Mr. Powers, a U.S. citizen, participates in a US 401(k) Plan which allows Mr. Powers to contribute his own funds and the Company provides an 11% contribution to his 401(k) Plan.

Mr. Pope's
prior employer maintained a Supplemental Executive Retirement Plan, or a SERP, which Mr. Pope participated in prior to his employment with us. The SERP was
intended to provide him with a $250,000 annual retirement benefit for a period of ten years, or in the event of Mr. Pope's death prior to retirement, a death benefit to his beneficiaries of
$1,500,000. Within Mr. Pope's previous employment agreement, as well as his new employment agreement with us, we agreed to provide Mr. Pope with the same retirement benefits to which he
would have been entitled under the SERP. Mr. Pope's prior employer had begun to fund Mr. Pope's SERP benefit by way of a life insurance policy on the life of Mr. Pope, which we
took over as both owner and beneficiary in 2006 in connection with Mr. Pope's execution of his previous employment agreement with us. We intend to continue funding this life insurance policy as
a means of financing Mr. Pope's eventual retirement or death benefit.

Table of Contents

Perquisites.We provide our named executive officers with certain perquisites that we feel are in line with industry standards as well
as peer
companies within our geographic region, and which are necessary to stay competitive with regard to executive compensation. Certain of these perquisites relate to items that are "carry-overs," or
perquisites that were provided to the executives when they were previously
employed by EnCana Corporation or its affiliates, and we felt that it would be unjust to take such benefits away from the executives following their employment with us. Our named executives (other
than Mr. Powers) received additional payments to be applied to expenses for home computers, club membership (including industry organizations) and other personal expenses, as well as a monthly
automobile allowance and paid parking at our office facilities.



As previously discussed, the compensation committee believed that it was important to examine and potentially alter our overall
compensation structure and of our executives to more accurately reflect a market-based compensation structure that was appropriate for a publicly traded limited partnership. Therefore, after
performing such examination over the course of fiscal 2011, with the assistance of Cogent Compensation Partners, the compensation committee put in place a new comprehensive plan, which included
changes to base salary, short term incentives and long term incentives. This new compensation plan was implemented on April 1, 2011 and is briefly described below.

Base SalaryOn March 24, 2011, our board approved, on the recommendation of the compensation committee, changes to many employees
and
executives base salary. These changes became effective on April 1, 2011 and were a result of the examination and surveys of the market conducted by the compensation committee and Cogent
Compensation Partners over the course of fiscal year 2011. The changes were made to bring the base salary compensation in-line with other similarly-situated market comparables for publicly
traded entities, and in particular, limited partnerships.

Short Term Incentive Plan.On March 24, 2011, our board approved the framework of a short term incentive bonus plan applicable to
our
employees, including our named executive officers, for the 2012 fiscal year (which will begin on April 1, 2011) (the "STI"). This is the functional equivalent to the former annual cash bonus
compensation previously awarded under the fiscal 2011 compensation structure. The STI will provide annual bonuses based upon the achievement, if any, of our company performance targets, as well as
individual performance targets for certain employees, which we expect our Compensation Committee to set each year.

Long Term Incentive Plan.On March 24, 2011, our board established a cash-based long-term compensation plan for our
employees that we intend to use utilize during the fiscal year 2012 (the "PUPP"), as previously described. A principal purpose of the PUPP is to further
align the interests of participants in the PUPP, including our named executive officers, with the interest of our unit holders by providing certain employees and directors with a phantom unit award. A
"Phantom Unit" is a notional unit granted under the PUPP that represents the right to receive a cash payment equal to the fair market value of a unit of our common units (a "Unit"), following the
satisfaction of certain time periods and/or certain performance criteria.

The
PUPP will be primarily administered by our compensation committee under the overall direction of our board. The compensation committee will determine all of the terms and conditions
of each Phantom Unit award, subject to the terms and conditions required by the PUPP, and will grant Phantom Units to eligible participants at such times as the compensation committee may determine to
be appropriate. Such terms and conditions will be set forth in an individual Phantom Unit award agreement at the time of each grant of Phantom Units.

85

Table of Contents

Phantom
Unit awards under the PUPP will become vested upon the date or dates on which the compensation committee sets forth in the award agreement and subject to such performance
conditions as the compensation committee may assign to the particular Phantom Unit award. Unless the compensation committee specifies otherwise within the award agreement, Phantom Units will be
granted unvested and subject to both time and performance conditions. The default time period over which the Phantom Unit will vest will be three years from the date of grant, and the performance
measure will be based upon DCF and TUR metrics compared to such metrics at a select group of peer companies to us, except that the we expect that initial grants of Phantom Units will be grossed up to
167% of the target amount for each recipient and will vest 2/3 after one year and 1/3 after two years (in order that 100% of the target number will vest in one year and
2/3 of the target number initially granted (together with an additional 1/3 of a subsequent grant assuming the PUPP is administered as expected). "DCF" is defined within
the PUPP as distributed cash flow from a trust, partnership or corporation calculated based on the appreciation in the distributed cash flow per Unit or any other applicable publicly traded security
during the performance period. "TUR" is defined within the PUPP as the total unitholder return of a trust, partnership or corporation, calculated based on the appreciation in the price of a Unit or
other applicable traded security during the performance period. The DCF and TUR metrics will be calculated based on our percentile ranking during the applicable performance period compared to a peer
group that will be determined by the compensation committee from time to time. Provided that we have satisfied our minimum quarterly distribution targets for the underlying Units, the Phantom Units
will typically vest in accordance with the following performance criteria:

The PUPP participants must also generally be providing services to us or one of our affiliates in order for their Phantom Unit to
become vested. The compensation committee will have authority to provide for accelerated vesting provisions in the event of a termination of
employment or a change in control. Generally, in the event of a PUPP participant's death, disability, retirement, or termination of employment without cause, unvested Phantom Units will vest on a pro
rata basis by taking into account the number of days of actual service provided to us or one of our affiliates versus the number of days in the entire vesting period for the award. Where the Phantom
Units are subject to performance criteria, a "target" level of performance will be applied upon any acceleration of vesting, such that a maximum of 100% of the Phantom Units originally granted will
become vested. Where vesting of the Phantom Units are based solely on time, the Phantom Units will also vest on a pro rata basis calculated by the number of days of service provided to us or one of
our affiliates from the grant date to the vesting date. Unless otherwise provided in an individual award agreement, if we incur a change in control, and the holder is also terminated, the Phantom
Units will also receive accelerated vesting, with any performance-based vesting provisions being accelerated at the "target" performance level.

The
Phantom Units will also be granted with distribution equivalent rights. During the period the Phantom Unit is outstanding, any distribution that we pay to Unit holders generally will
also be credited to the Phantom Unit holder in the form of additional Phantom Units. The number of additional Phantom Units to be credited to a PUPP participant's account will be determined by

the event that a PUPP participant is subject solely to the United States securities and tax laws rather than Canadian tax or securities laws, the PUPP also contains a schedule of

Mr. Pope's Employment Agreement.Mr. Pope's previous employment agreement was entered into with Niska Gas Storage, and
subsequently
amended by an agreement that placed his employment with AECO Gas Storage Partnership (by its managing partner Niska Gas Storage Canada ULC) in 2009. Following our IPO and certain corporate
restructuring events, we entered into a new employment agreement with Mr. Pope to clarify his position as the President and Chief Executive Officer of Niska Partners Management ULC and
all of its subsidiaries, including Niska Gas Storage Partners LLC. The term of the new employment agreement began on April 1, 2011 and will continue for an indefinite period of time, but
may be terminated at the discretion of Mr. Pope or us, with or without cause. Mr. Pope's compensation pursuant to the new employment agreement will include an annual base salary of not
less than $550,000 Canadian dollars (approximately $540,980 in US dollars using the exchange rate in effect on March 31, 2011), payable in semi-monthly installments. Mr. Pope
will be entitled to participate in the PUPP and receive phantom unit awards. The new employment agreement provides Mr. Pope with an annual allowance of $24,000 per year for expenses related to
home computers, annual social club memberships and other personal expenses, a $6,000 annual supplemental health care allowance, a $2,000 (Canadian dollars) per month automobile allowance and four
weeks of vacation per year. Mr. Pope will remain eligible to participate in our RRSP
Plan/Non-Registered Employee Savings Plan, where he will receive an employer contribution on his behalf equal to eight percent (8%) of his annual base salary, as well as an employer
matching contribution that will be capped at five percent (5%) of his annual base salary.

The
terms and conditions relating to potential severance payments, as well as our rationale for providing these benefits to Mr. Pope, are further described in the section below
titled "Potential Payments Upon Termination or Change in Control."

Mr. Pope's Retirement.On June 8, 2011, Mr. Pope informed our board that he will be resigning as our President and Chief
Executive Officer, effective July 1, 2011. We expect Mr. Pope to remain a member of our board following his resignation as our President and Chief Executive Officer. As a member of our
board, Mr. Pope will be entitled to the same compensation as our directors who are not officers, employees or paid consultants and advisors of our manager or its affiliates.

Report of the Compensation Committee

In light of the foregoing, as required by Item 407(e)(5) of Regulation S-K, our compensation committee has
reviewed and discussed the Compensation Discussion and Analysis with our management and, based on such review and discussions, has recommended to the board of directors that the Compensation
Discussion and Analysis be included in this annual report.

The following table and footnotes provide information regarding the compensation of the named executive officers during the fiscal
years ended March 31, 2009, March 31, 2010 and March 31, 2011. The year "2009" refers to the fiscal year of April 1, 2008 through March 31, 2009, the year "2010"
refers to the fiscal year of April 1, 2009 through March 31, 2010, and the year "2011" refers to the fiscal year of April 1, 2010 through March 31, 2011. Compensation to
our named executive officers was paid primarily in Canadian dollars, but is reported in U.S. dollars in the tables that follow. An exchange rate of 0.952 U.S. dollars was used for the 2009 and 2010
amounts for each Canadian dollar (the exchange rate reported by the Bank of Canada on December 31, 2009) and 0.9836
U.S dollars for each Canadian dollar was used for the 2011 amounts of each Canadian dollar (the exchange rate reported by the Bank of Canada on March 31, 2011). The only exception to this rule
is for our new Chief Financial Officer, Vance E. Powers, who is a US resident and paid in US dollars.

We did not grant plan-based awards to our named executive officers during the fiscal year ended March 31, 2011.



The term of Mr. Pope's employment agreement that was effective as of March 31, 2011 began on August 20, 2006 and
was set to continue for an indefinite period of time unless earlier terminated by either party. The agreement provided Mr. Pope with an annual base salary of $450,000 (Canadian dollars, which,
using the exchange rate noted within the Summary Compensation Table below, would be approximately $442,620 US dollars). Mr. Pope was entitled to receive a cash bonus from the discretionary cash
pool described further in the "Compensation Discussion and Analysis" above, along with certain perquisites that have been disclosed within the "All Other Compensation" section of the Summary
Compensation Table above. Provisions relating to Mr. Pope's termination of employment, non-competition and non-solicitation are described in detail below.



As of March 31, 2011, the risk of forfeiture had lapsed with respect to all equity awards held by our named executive officers.

89

---



Table of Contents



The named executive officers did not hold any options that were exercised or any unit awards that vested during the year ended
March 31, 2011.



We do not maintain or sponsor a pension plan for our named executive officers.



We do not maintain or sponsor a nonqualified deferred compensation plan for our named executive officers.



As of March 31, 2010, Mr. Pope was the only named executive officer subject to a formal employment agreement that will
provide the officer with certain payments and benefits in connection with his termination of employment. And as all outstanding equity awards held by our remaining executive officers have become fully
vested, there would be no amounts payable or accelerated with respect to a termination of employment or a change in control. Mr. Pope's employment agreement that was effective as of
March 31, 2011 with the AECO Partnership was executed in August of 2006 and contained the terms and conditions below.

In
the event we terminated Mr. Pope for Just Cause (as defined below), all compensation payments to Mr. Pope would have ceased. If we terminated Mr. Pope other than
for Just Cause, or Mr. Pope terminated his employment for Good Reason (as defined below), Mr. Pope would have received a cash payment of $900,000 (Canadian dollars, or approximately
$885,240 in US dollars using the exchange rate as of March 31, 2011) less applicable withholding taxes, which amount represented two years of
salary for Mr. Pope. Where Mr. Pope voluntarily resigned without Good Reason (including a normal retirement), or his employment relationship was terminated due to death or a mental or
physical incapacity, all compensation payments would have ceased at such time. Canada has traditionally had a very robust jurisprudence regarding the notice provided to employees or payments made in
lieu of notice (severance), payable to employees upon certain terminations, and we felt that providing the $900,000 Canadian dollar payment in the event of Mr. Pope's termination other than for
Just Cause or for Good Reason was an equitable result to both Mr. Pope and us in light of the uncertain, but typically generous, severance payments authorized in the Canadian courts to
executives that have litigated a severance issue due to an uncertain or nonexistent employment agreement provision on this subject.

Any
payments that Mr. Pope would have been entitled to receive upon a termination of employment would have been conditioned upon his execution of a general release in our favor.
Mr. Pope would also have remained subject to the confidentiality provisions of his employment agreement, as well as the non-competition provisions for a restricted period of one
year and the non-solicitation provisions for a restricted period of six months following a termination of employment.

"Good
Reason" was defined as (1) our requirement that Mr. Pope devote the majority of his time to duties inconsistent with his position; (2) a reduction of 20% or
more of Mr. Pope's annual base salary; (3) the required relocation of Mr. Pope's primary work location by more than 50 miles from his primary work location at the time of his
entrance into the employment agreement; (4) our refusal to allow Mr. Pope to participate in our incentive compensation plans to which are comparable to the same plans in which he
participated as an employee of his previous employer; or (5) our refusal to allow Mr. Pope to participate in employment benefit programs that are comparable to the same plans in which he
participated as an employee of his previous employer.

90

---



Table of Contents

"Just
Cause" included (1) any improper conduct by Mr. Pope which was materially detrimental to us, our business, our employees or our standing in the community;
(2) a willful failure to properly carry out his duties; (3) Mr. Pope's conviction of a criminal offense; or (4) any theft, conversion or misappropriation, attempted theft,
conversion or misappropriation of any of our property, clients, business or business opportunities.

Mr. Pope's
employment agreement also provided for the continuation of Mr. Pope's SERP benefit. See "Compensation Discussion and AnalysisOther
Benefits."

Following
the fiscal year ending March 31, 2011, we entered into a new employment agreement with Mr. Pope that became effective on April 1, 2011. This new employment
agreement also provides
Mr. Pope with potential severance benefits in connection with certain terminations of his employment that are similar to the terms of the severance provided above. As with his previous
employment agreement, Mr. Pope will receive a $900,000 cash payment (Canadian dollars, or approximately $885,240 in US dollars using the exchange rate as of March 31, 2011) in the event
that he is terminated by us other than for Just Cause or he resigns with Good Reason. One slight difference between the previous employment agreement and the new employment agreement is that
subclause (4) of the Good Reason definition described above has been modified to address our refusal to allow Mr. Pope to participate in our incentive compensation plans that are
provided for within the new employment agreement, rather than a refusal to permit him to participate in incentive plans comparable to the incentive plans that Mr. Pope participated in at his
previous employer. The new employment agreement states that both Mr. Pope and we will agree that in the event this severance payment is provided to Mr. Pope, it will constitute our one
and final obligation to him in connection with a termination of his employment, and it will satisfy any and all statutory obligations we may have with respect to any benefits Mr. Pope was
entitled to receive at the time of his termination of employment. As with his previous employment agreement, Mr. Pope will not be entitled to any severance in the event of a termination due to
his death, a mental or physical incapacity, or a resignation. Mr. Pope's new employment agreement also contains non-competition provisions for a restricted period of one year and
non-solicitation provisions for a restricted period of six months following a termination of employment.

Risk Assessment

Our compensation committee has reviewed our compensation policies as generally applicable to our employees and believes that our
policies do not encourage excessive and unnecessary risk-taking, and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us.

Our
compensation philosophy and culture support the use of base salary, certain performance-based compensation that are generally uniform in design and in operation throughout our
organization and with all levels of employees. These compensation policies and practices are centrally designed and administered, and are substantially identical between our business divisions. In
addition, the following specific factors, in particular, reduce the likelihood of excessive risk-taking:

Item 13.    Certain Relationships and Related Transactions, and Director Independence.

Certain Relationships and Related Party Transactions

Holdco owns 16,304,745 common units and 33,804,745 subordinated units, representing approximately 74.1% of our units and the incentive
distribution rights. In addition, our manager owns a 2% managing member interest in us.



During the year ended March 31, 2011, we entered into various agreements that effected our formation transactions, including the
transfer of assets to, and the assumption of liabilities by, us and our subsidiaries. These agreements were not the result of arm's-length negotiations and the terms of these agreements were not
necessarily at least as favorable to the parties to these agreements as the terms which could have been obtained from unaffiliated third parties. All of the transaction expenses incurred in connection
with our formation transactions, including the expenses associated with transferring assets to our subsidiaries were paid from the proceeds of our IPO.



On March 5, 2010, our subsidiary, AECO Partnership, entered into a services agreement with certain affiliates of Holdco pursuant
to which it would provide employees to manage certain development projects for Holdco or its affiliates in return for a service fee that is to be agreed upon between the parties from time to time.
AECO Partnership subsequently assigned its rights and obligations under the services agreement to Niska Gas Storage Management ULC. The initial term of the services agreement expired on
March 31, 2011, at which point it was automatically renewed for an additional one-year term. The current term will expire on March 31, 2012, at which point it will
automatically renew for an additional one-year term unless it is terminated.



Under our Operating Agreement, we have agreed to register for resale under the Securities Act and applicable state securities laws any
common units, subordinated units or other company securities proposed to be sold by our manager or any of its affiliates or their assignees if an exemption from the registration requirements is not
otherwise available. These registration rights continue for two years following any withdrawal or removal of our manager. We are obligated to pay all expenses incidental to the registration, excluding
underwriting discounts and commissions.

In
addition, we have entered into a registration rights agreement with Holdco. A copy of the form of registration rights agreement is filed as an exhibit to this report and is
incorporated herein by reference. Pursuant to the registration rights agreement, we will be required to file a registration statement to register the common units and subordinated units issued
to Holdco and the common units issuable upon the conversion of the subordinated units upon request of Holdco. The registration rights
agreement also includes provisions dealing with holdback agreements, indemnification and contribution and allocation of expenses. These registration rights are transferable to affiliates of Holdco
and, in certain circumstances, to third parties.

Policies Relating to Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our manager and its affiliates
(including Holdco), on the one hand, and us and our unaffiliated members, on the other hand. Our directors and officers have fiduciary duties to manage our manager in a manner beneficial to its
owners. At the same time, our manager has a fiduciary duty to manage us in a manner beneficial to our unitholders. Our Operating Agreement contains provisions that specifically

94

---



Table of Contents

define
our manager's fiduciary duties to the unitholders. Our Operating Agreement also specifically defines the remedies available to unitholders for actions taken that, without these defined
liability standards, might constitute breaches of fiduciary duty under applicable Delaware law. The Delaware Limited Liability Company Act, which we refer to as the Delaware Act, provides that
Delaware limited liability companies may, in their Operating Agreements, expand, restrict or eliminate the fiduciary duties otherwise owed by a manager to members and us.

Under
our Operating Agreement, whenever a conflict arises between our manager or its affiliates, on the one hand, and us or any unaffiliated member or our board as our manager's
delegate, on the other, our manager will resolve that conflict. Our manager has delegated this responsibility, along with the power to conduct our business, to our board. Our board may, but is not
required to, seek the approval of such resolution from the conflicts committee of our board. An independent third party is not required to evaluate the fairness of the resolution.

Whenever
a potential conflict of interest exists or arises between the manager or any of its affiliates, on the one hand, and us or any of our members, on the other, the resolution or
course of action in respect of such conflict of interest shall be permitted and deemed approved by all our members, and shall not constitute a breach of our Operating Agreement, of any agreement
contemplated, or of any duty if the resolution or course of action in respect of such conflict of interest is:



If
our board does not seek approval from the conflicts committee and determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of
the standards set forth in the third and fourth bullet points above, then it will be presumed that, in making its decision, our board acted in good faith, and in any proceeding brought by or on behalf
of us or any of our unitholders, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. Unless the resolution of a conflict is specifically provided
for in our Operating Agreement, our board or the conflicts committee of our board may consider any factors it determines in good faith to consider when resolving a conflict. When our Operating
Agreement requires someone to act in good faith, it requires that person to reasonably believe that he is acting in the best interests of us, unless the context otherwise requires. See "Management"
for information about the conflicts committee of our board.

The
transactions described above under "Agreements With Affiliates" were described in our registration statement relating to our IPO and deemed approved by all our members
under the terms of our Operating Agreement.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Niska Gas Storage Partners LLC ("Niska Partners") is responsible for establishing and maintaining adequate
internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable, but not absolute, assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. A company's internal control
over financial reporting includes those policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions
of the assets of the company; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally
accepted in the United States of America, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial
statements.

Because
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future
periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management
evaluated Niska Partners' internal control over financial reporting as of Match 31, 2011. In making this assessment, management used the criteria set forth by the Committee of
Sponsoring Organizations of the Treadway Commission in Internal ControlIntegrated Framework ("COSO"). As a result of this assessment and based on the criteria in the COSO framework,
management has concluded that, as of March 31, 2011, Niska Partners' internal control over financial reporting was effective.

Niska
Partners' independent registered public accounting firm, KPMG LLP, has audited the internal control over financial reporting. Their opinion on the effectiveness of Niska
Partners' internal control over financial reporting appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The
Board of Directors
Niska Gas Storage Partners LLC:

We
have audited Niska Gas Storage Partners LLC's (the "Company") internal control over financial reporting as of March 31, 2011, based on criteria established in Internal ControlIntegrated
Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's
management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the
accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our
audit.

We
conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our
audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In
our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2011, based on criteria established in Internal ControlIntegrated
Frameworkissued by COSO.

We
also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Niska Gas Storage
Partners LLC as of March 31, 2011, and the related consolidated statements of earnings and comprehensive income, partners' equity, and cash flows for the year then ended March 31,
2011, and our report dated June 10, 2011 expressed an unqualified opinion on those consolidated financial statements.

We

obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audit provides a reasonable basis for our opinion.

In
our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of March 31, 2011, and
the results of its operations and its cash flows for the year then ended in conformity with U.S. generally accepted accounting principles.

flows prior to May 17, 2010 have been prepared on a combined basis of accounting.

Niska Gas Storage Partners LLC        Notes to Consolidated Financial Statements        (Thousands of U.S. dollars)

1. Description of Business

Niska Gas Storage Partners LLC ("Niska Partners" or the "Company") is a publicly-traded Delaware limited liability company (NYSE:NKA) that was formed on January 27, 2010 to
acquire certain assets of Niska GS Holdings I, LP and Niska GS Holdings II, LP (collectively, "Niska Predecessor"). On May 11, 2010, Niska Partners priced its initial public
offering (the "IPO") of 17,500,000 common units at an offering price of $20.50 per unit. Upon closing of the IPO on May 17, 2010, Niska Partners received net proceeds of $333.5 million,
after deducting the underwriters' discount, structuring fees and offering expenses. Upon closing the IPO, Niska Predecessor's parent Niska Sponsor Holdings Coöperatief U.A. ("Sponsor
Holdings" or "Holdco"), exchanged 100% of its equity interest in Niska Predecessor for a 2% Managing Member's interest, 33,804,745 subordinated units, 13,679,745 common units of Niska Partners, and
all of the Incentive Distribution Rights ("IDRs"). Prior to the closing of the IPO, Niska Partners had no activity.

As
partial consideration for the contribution of 100% of Niska Predecessor's equity interest to Niska Partners, Sponsor Holdings held the right to receive any common units not purchased
pursuant to the expiration of a 30-day option granted to the underwriters of the IPO to purchase up to an additional 2,625,000 common units. Upon the close of business on June 10,
2010, the 30-day option granted to the underwriters expired unexercised. Pursuant to the Contribution Agreement, 2,625,000 common units were issued to Sponsor Holdings on June 11,
2010.

At
March 31, 2011, Niska Partners had 33,804,745 common units outstanding and 33,804,745 subordinated units outstanding. Of these amounts, 16,304,745 common units and all of the
subordinated units are owned by Sponsor Holdings, along with a 2% Managing Member's interest in the Company and all of the IDRs. Including all of the common and subordinated units owned by Sponsor
Holdings, along with the 2% Managing Member's interest, Sponsor Holdings has a 74.6% ownership interest in the Company, excluding the IDRs. The remaining 17,500,000 common units, representing a 25.4%
ownership interest excluding the IDRs, are owned by the public.

As
a result of these transactions, Niska Partners became the owner of substantially all of the assets of Niska Predecessor, except for the assets of Starks Gas Storage LLC
("Starks") and Coastal Bend Gas Storage, LLC ("Coastal Bend"), two projects under development that were distributed to an affiliate of Niska Partners. These projects represented assets and
partners' equity included in Niska Predecessor's financial statements of approximately $25.7 million at March 31, 2010. The transfers of the equity interests in Starks and Coastal Bend
were treated as equity distributions in the accompanying financial statements.

Niska
Partners operates the Countess and Suffield gas storage facilities (collectively, the AECO Hub) in Alberta, Canada, and the Wild Goose and Salt Plains gas storage
facilities in California and Oklahoma, respectively. Each of these facilities markets gas storage services in addition to optimizing storage capacity with its own proprietary gas purchases.

2. Significant Accounting Policies

Basis of presentation

These consolidated financial statements have been prepared to reflect the consolidated financial position, results of operations and
cash flows of Niska Partners and its subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America

("GAAP").
The results from the pre-IPO period of April 1, 2010 to May 16, 2010, as well as the comparative years' disclosures for Niska Predecessor, have been prepared to
reflect the combined financial position, results of operations, and cash flows of the predecessor Partnerships and their subsidiaries and have been prepared in accordance with GAAP.

The
exchange of equity interests pursuant to the Contribution Agreement has been accounted for as a transfer between entities under common control as described in the Financial
Accounting Standards Board (the "FASB") Accounting Standards Codification ("ASC") 805-50-15. Accordingly, the financial information for Niska Partners included in this report
includes the financial information for Niska Predecessor for all periods presented prior to the closing of the IPO.

These
financial statements include the accounts of Niska Partners and its wholly-owned subsidiaries, including AECO Gas Storage Partnership, Wild Goose Storage LLC, Niska Gas
Storage, LLC and Salt Plains Storage, LLC, Access Gas Services Inc., Access Gas Services (Ontario) Inc., Access Gas Services (Alberta) Inc., EnerStream Agency
Services Inc., and Niska Partners Management ULC. All material inter-company transactions have been eliminated.

As
the closing of the Company's IPO occurred on May 17, 2010, the earnings for the year ended March 31, 2011 have been determined pro-rata to reflect earnings
on a pre- and post-IPO basis. As part of the process of allocating revenues and expenses to both periods, the Company assessed the fair value of its risk management assets and
liabilities as of the closing date, resulting in an unrealized gain for the pre-IPO period and an unrealized loss for the post-IPO period. The net unrealized loss for the
period from May 17, 2010 to March 31, 2011 is reflected in the per-unit information presented in the consolidated statement of earnings and comprehensive income.

Use of estimates

In preparing these financial statements, Niska Partners is required to make estimates and assumptions that affect both the amount and
timing of recording assets, liabilities, revenues and expenses since the determination of these items may be dependent on future events. Management uses the most current information available and
exercises careful judgment in making these estimates. Although Management believes that these consolidated financial statements have been prepared within limits of materiality and within the framework
of its significant accounting policies summarized below, actual results could differ from these estimates. Changes in estimates are accounted for on a prospective basis.

Management
has made key assumptions at the balance sheet date that have a risk of causing a material adjustment to the carrying amounts of assets and liabilities relating to the
valuation of risk management assets and liabilities, inventory, and goodwill. Estimates affect, among other items: valuing identified intangible assets; evaluating impairments of
long-lived assets; effectiveness of cushion gas; establishing estimated useful lives for long-lived assets; estimating revenues and expense accruals; assessing income tax
expense and the requirement for a valuation allowance against the deferred income tax asset; valuing asset retirement obligations and in determining liabilities, if any, for legal contingencies.

Revenue recognition

The Company's assessment of each of the four revenue recognition criteria as they relate to its revenue producing activities is as
follows:

Persuasive evidence of an arrangement exists.The Company's customary practices are to enter into a written contract, executed by both
the customer
and the Company.

Delivery.Delivery is deemed to have occurred at the time the natural gas is delivered and title is transferred, or in the case of
fee-based arrangements, when the services are rendered. To the extent the Company retains its inventory, delivery occurs when the inventory is subsequently sold and title is transferred to
the third party purchaser.

The fee is fixed or determinable.The Company negotiates the fee for its services at the outset of their fee-based arrangements. In
these
arrangements, the fees are nonrefundable. The fees are generally due on the 25th of the month following the delivery or services rendered. For other arrangements, the amount of
revenue is determinable when the sale of the applicable product has been completed upon delivery and transfer of title.

Collectability is reasonably assured.Collectability is evaluated on a customer-by-customer basis. New and existing customers
are subject to a credit review process, which evaluates the customers' financial position (e.g. cash position and credit rating) and their ability to pay. If collectability is not considered
reasonably assured at the outset of an arrangement in accordance with the Company's credit review process, revenue is recognized when the fee is collected.

Long-term
contract revenue consists of monthly storage fees and fuel and commodity charges for injections and withdrawals. Long-term contract revenue is accrued
on a monthly basis in accordance with the terms of the customer contracts. Customer charges for injections and withdrawals are recorded in the month of injection or withdrawal.

Short-term
contract revenue consists of fees for injections and withdrawals, which include fuel and commodity charges. One half of the fees are earned at the time of
injection by the customer and one half of the fees are earned at the time of withdrawal by the customer.

Energy
trading contracts resulting in the delivery of a commodity where Niska Partners is the principal in the transaction are recorded as optimization revenues at the time of physical
delivery. Realized and unrealized gains and losses on financial energy trading contracts are included in optimization revenue (see Note 11).

Sales
taxes collected from customers and remitted to governmental authorities are excluded from revenues in the consolidated statements of earnings and comprehensive income.

Cash and cash equivalents

Niska Partners considers all highly liquid investments purchased with an initial maturity of three months or less to be cash
equivalents.

2. Significant Accounting Policies (Continued)

Margin deposits

Cash held in margin represents the right to receive or the obligation to pay cash collateral under a master netting arrangement that
has not been offset against derivative positions. These derivatives are marked-to-market daily; the profit or loss on the daily position is then paid to, or received from, the
account as appropriate under the terms of the Company's contract with its broker.

Natural gas inventory

The Company's inventory is natural gas injected into storage which is held for resale. Long-term inventory represents
non-cycling working gas. Non-cycling working gas is injected by the Company on a temporary basis to increase pressure within the reservoirs to allow it to market higher cycling
contracts or previously un-saleable gas from an underutilized reservoir that can be sold into the market when the Company adds mechanical compression to the reservoir. This mechanical
compression will allow access to natural gas that was previously required to maintain pressure within the reservoir. Inventory is valued at the lower of weighted average cost and market. Costs to
store the gas are recognized as operating expenses in the period the costs are incurred. For the year ended March 31, 2011, the Company recorded a write-down of $ nil,
(March 31, 2010$3.4 million; March 31, 2009$62.3 million), which is included in revenues in Optimization, net.

Property, plant and equipment

Property, plant and equipment are recorded at cost when purchased. Depreciation is computed using the declining balance method for each
category of asset using the following rates:

Facilities

5% and 15%Wells

5%Pipelines and measurement

5%Office furniture and fixtures

20%Computer hardware and software

30%Other

10%


Certain
volumes of gas defined as cushion gas are required for maintaining a minimum field pressure. Cushion gas is considered a component of the facility and as such is not amortized
because it is expected to ultimately be recovered and sold. Cushion gas is monitored to ensure that it provides effective pressure support for the facility. In the event that gas moves to another area
of the reservoir where it does not provide effective pressure support, a loss is recorded, within depreciation expense, equal to the estimated volumes that have migrated (see Note 4).

Repairs,
maintenance and renewals that do not extend the useful lives of the assets are expensed as incurred. Interest costs for the construction or development of long-lived
assets held by operational entities are capitalized and amortized over the related asset's estimated useful life (see Note 4).

Asset retirement obligations

Niska Partners records a liability for an asset retirement obligation when the legal obligation to retire the asset has been incurred
with an offsetting increase to the carrying value of the related

F-13

Asset retirement obligations (continued)

tangible
long-lived asset. The recognition of an asset retirement obligation requires that management make numerous estimates, assumptions and judgments regarding such factors as the
estimated probabilities, amounts and timing of settlements; the credit-adjusted risk-free rate to be used; inflation rates, and future advances in technology. In periods subsequent to
initial measurement of the liability, the Company must recognize changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate
of undiscounted cash flows. Over time, the liability is accreted to its future value, and the capitalized cost is depreciated over the useful life of the related asset. Accretion of the asset
retirement obligations due to the passage of time is recorded as an expense in the statement of earnings. Upon settlement of the liability, the Company either settles the obligation for its recorded
amount or incurs a gain or loss.

Impairment of long-lived assets

Niska Partners evaluates whether events or circumstances have occurred that indicate that long-lived assets may not be
recoverable or that the remaining useful life may warrant revision. When such events or circumstances are present, the Company assesses the recoverability of long-lived assets by
determining whether the carrying value will be recovered through the expected undiscounted future cash flows. In the event that the sum of the expected future cash flows resulting from the use of the
asset is less than the carrying value of the asset, an impairment loss equal to the excess of the asset's carrying value over its fair value is recorded.

Goodwill and other intangible assets

Niska Partners accounts for business acquisitions using the purchase method of accounting and, accordingly, the assets and liabilities
of the acquired entities are recorded at
their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired is attributed to goodwill.

Goodwill
is not amortized and is re-evaluated on an annual basis or more frequently if events or changes in circumstances indicate that the asset might be impaired.

Goodwill
is tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its
carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators, competition, sale or disposition of a
significant portion of the business or other factors. The performance of the test involves a two-step process. The first step of the impairment test involves comparing the fair values of
the applicable reporting units with their aggregate carrying values, including goodwill. If the carrying amount exceeds the fair value of the reporting unit, the Company performs the second step of
the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit's
goodwill with the carrying value of that goodwill.

Other
intangible assets represent contractual rights obtained in connection with a business combination that had favorable contractual terms relative to market as of the acquisition
date.

Intangible
assets representing customer contracts are amortized over their useful lives. These assets are reviewed for impairment as impairment indicators arise. When such events or
circumstances are

present,
the recoverability of long-lived assets is assessed by determining whether the carrying value will be recovered through the expected undiscounted future cash flows. In the event
that the sum of the expected future cash flows resulting from the use of the asset is less than the carrying
value of the asset, an impairment loss equal to the excess of the asset's carrying value over its fair value is recorded.

Pipeline
rights of way are formal agreements granting rights of way in perpetuity and are not subject to amortization but are subject to an annual impairment test.

Risk management activities

The Company uses natural gas derivatives and other financial instruments to manage its exposure to changes in natural gas prices, and
foreign exchange rates. These financial assets and liabilities, which are recorded at fair value on a recurring basis, are included in one of three categories based on a fair value hierarchy with
realized and unrealized gains (losses) recognized in earnings (see Note 11).

The
fair value of the Company's derivative risk management contracts are recorded as a component of risk management assets and liabilities, which are classified as current or
non-current assets or liabilities based upon the anticipated settlement date of the contracts.

Foreign currency translation

The functional and reporting currency of the Company is the U.S. dollar. Non-U.S. dollar denominated monetary items are
translated into U.S. dollars at the rate of exchange in effect at the balance sheet date. Non-U.S. dollar denominated non-monetary items are translated to U.S. dollars at the
exchange rate in effect when the transaction occurred. Revenues and expenses denominated in foreign currencies are translated at the average exchange rate in effect during the period. Foreign exchange
gains or losses on translation are included in income.

Deferred charges

Deferred charges relate to costs incurred on the issuance of debt and are amortized over the term of the related debt to interest
expense using the effective interest method for
cost related to the senior notes offering and straight-line for deferred charges incurred on the revolving credit facility.

Income taxes

The Company is not directly a taxable entity. Income taxes on its income are the responsibility of the individual unit holders and have
accordingly not been recorded in the consolidated financial statements. However, Niska Partners does own corporate subsidiaries, which are taxable corporations subject to Canadian federal and
provincial income taxes, which are included in the consolidated financial statements.

Income
taxes on the Canadian corporate subsidiaries are provided based on the asset and liability method, which results in deferred income tax assets and liabilities arising from
temporary differences. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or
deductible amounts in future years. This method requires the effect of tax rate changes on current and accumulated deferred income taxes to be reflected in the period in which the rate change was
enacted. The asset and liability method also requires that deferred income tax assets be reduced by a valuation allowance unless it is more likely than not that the assets will be realized.

2. Significant Accounting Policies (Continued)

Income taxes (continued)

The Company's policy is to recognize accrued interest and penalties on accrued tax balances as components of interest expense. The
Company had not accrued any interest and expense penalties during the periods reported.

The
Canadian subsidiaries remain subject to examination by Canadian federal and provincial tax jurisdictions for all years filed after 2006. The Company's unit holders, relative to the
Company, remain subject to examination by US federal and state tax jurisdictions for years from 2007 and beyond.

Long term equity-based incentives

Effective for the fiscal year beginning April 1, 2011, Niska Partners' compensation committee has approved awards of phantom
units with distribution equivalent rights to certain key employees. These awards include both time-based and performance-based components and are accounted for as prescribed in ASC 718,
"Stock Compensation."

Unit
award grants will be classified as liabilities. Fair value of the unit grants will be determined on the date of grant and re-measured on the close of business at each
reporting period end until the settlement date. Fair value at each re-measurement date will be equal to the liability of the settlement expected to be incurred based on the anticipated
number of units vested adjusted for the payout threshold associated with the performance targets achieved by the Company as compared to its established peers. The pro-rata number of units
vesting will be calculated as the number of performance awards multiplied by the percentage of the requisite service period, plus additional units granted in lieu of the cash distributions paid on the
vested units.

Compensation
expense is calculated as the re-measured expected payout less previously-recognized compensation expense.

Certain
unit awards include performance and other provisions that can result in payouts to the recipients of 0% up to 200% of the amount of the award. Judgments and assumptions of the
final award payouts are inherent in the accruals recorded incentive compensation costs. The use of alternate judgments and assumptions could result in the recognition of different levels of
equity-based incentive compensation costs.

3. New Accounting Pronouncements

The following new accounting pronouncement was adopted in the periods noted and the effect of such adoption has been presented in the accompanying consolidated financial statements:

Fair Value Measurement (ASC 810-10)

Effective April 1, 2010, the Company is required to disclose additional fair value measurement information such as the level of
disaggregation required, inputs and valuation techniques used to measure fair value, transfers into and out of levels 1 and 2, and further details of movements within level 3. Additional
disclosures are provided in Note 11.

For
the year ended March 31, 2011, a loss of $5.5 million of cushion gas was recorded in depreciation and amortization expense on the consolidated statements of earnings
and comprehensive income for the estimated amount of cushion gas that had migrated (March 31, 2010$1.8 million; March 31, 2009$11.9 million).

During
the year ended March 31, 2011 $ nil impairment charges were recorded on long-lived assets (March 31, 2010$0.7 million;
March 31, 2009$2.1 million). The impaired assets relate to a project under development that was not included in the transfer of assets from Niska Predecessor to the Company
described in Note 1.

5. Goodwill and Other Intangible Assets

Goodwill

Prior to the IPO, the assets of Starks Gas Storage LLC, a subsidiary of Niska Predecessor, were distributed to an affiliate of
Niska Partners (see Note 1). Included in the distributed assets was goodwill totaling $2.4 million.

5. Goodwill and Other Intangible Assets (Continued)

The
goodwill of a Niska Partners' operating unit with a carrying amount of $21.9 million was written down to its implied fair value of $ nil at March 31, 2009, resulting in
an impairment charge of $21.9 million. The impairment charges were recorded following a period of overall negative economic conditions during the fiscal year ended March 31, 2009.
Declines were noted in the earnings multiples of designated peer group companies of each of the Partnerships' reporting units and were a factor in the resulting impairment charge. No impairment to
goodwill was required as at March 31, 2011 or March 31, 2010.

Determining
the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions. These assumptions are dependent on several
subjective factors including the timing of future cash flows and future growth rates. The fair value of Niska Partners' reporting units is determined based on a weighting of multiples of potential
earnings approaches which is classified as a Level 3 fair value measurement under FASB ASC 820. The multiples of earnings approach estimates fair value by applying multiples of potential
earnings, working gas capacity, and cycle-ability of similar entities. Results using the multiples of potential earnings and the multiples of gas capacity and cycle-ability are given equal weighting
when determining the valuation using this approach. The future operating projections are based on consideration of past performance and the projections and assumptions used in the Company's current
operating plans and adjusted for market participant assumptions as appropriate. The Company then assigns a weighting to the multiple of earnings to derive the fair value of the reporting unit.

Niska
has recorded a reclassification of non-amortizable intangible assets of $11.7 million, related to allocations made at the inception of Niska Predecessor which
were improperly classified as intangible assets; however are more appropriately classified as goodwill. As a result the classification was corrected in the fourth fiscal quarter of 2011. The
reclassification resulted in adjustments to deferred income tax liabilities of $5.5 million.

On
March 5, 2010, Niska Predecessor undertook a non-public senior notes (the "Senior Notes") offering to certain qualified institutional investors for 800,000 units
with an aggregate principal amount of $800.0 million, which were issued at par. The units were sold in an offering exempt from registration under the Securities Act of 1933 (the "Securities
Act") to qualified institutional investors in reliance on Rule 144A under the Securities Act and to non-U.S. persons in offshore transactions in reliance on Regulation S
under the Securities Act. On February 4, 2011, the Securities and Exchange Commission ("SEC") accepted and made effective Niska Partners' exchange offer whereby holders of the current Senior
Notes were permitted to exchange such Senior Notes for new freely transferable Senior Notes. The terms of the new units are identical to the units issued March 5, 2010; except that the new
units are registered under the Securities Act and generally do not contain restrictions on transfer. The exchange offer was completed on March 2, 2011.

Debt obligations (continued)

The Senior Notes are senior unsecured obligations which are: (1) effectively junior to Niska Partners' secured obligations;
(2) equal in right of payment with all existing and future senior unsecured indebtedness of the Company; and (3) senior in right of payment to any future subordinated indebtedness of
Niska Partners. The Senior Notes are fully and unconditionally guaranteed by Niska Partners and its direct and indirect subsidiaries on a senior unsecured basis, and are: (1) effectively junior
to each guarantor's secured obligations; (2) equal in right of payment with all existing and future senior unsecured indebtedness of each guarantor and (3) senior in right of payment to
any future subordinated indebtedness of each guarantor.

Interest
on the Senior Notes is payable semi-annually on March 15 and September 15 at a rate of 8.875% per annum. The Senior Notes will mature on
March 15, 2018. As at March 31, 2011, the estimated fair value of the Senior Notes was $868.0 million.

The
indenture governing the Senior Notes limits Niska Partners' ability to pay distributions in respect of, repurchase or pay dividends on its membership interests (or other capital
stock) or make other restricted payments. The limitation changes depending on a fixed charge coverage ratio, which is defined as the ratio of consolidated cash flow to fixed charges, each as defined
in the indenture governing the Senior Notes, and measured for the preceding four fiscal quarters.

Under
this limitation the indenture would have permitted the Company to distribute approximately $150 million as at March 31, 2011.

If
the fixed charge coverage ratio is greater than 1.75 to 1.0, Niska Partners is permitted to make restricted payments if the aggregate restricted payments since the date of closing of
its IPO, excluding certain types of permitted payments, are less than the sum of a number of items including, most importantly:



At
March 31, 2011, the fixed charge coverage ratio was 2.52 to 1.0 and Niska Partners was permitted to pay the distribution described in Note 12.

The
indenture does not prohibit certain types or amounts of restricted payments, including a general basket of $75.0 million of restricted payments.

The
indenture governing the Senior Notes contains certain other covenants that, among other things, limit the Company's and certain of the Company's subsidiaries' ability to incur
additional indebtedness, pay dividends on, repurchase or make distributions in respect of the Company's capital stock or make other restricted payments, make certain investments, sell, transfer, or
otherwise convey certain assets, create liens, consolidate, merge, sell or otherwise dispose of all or substantially all of the Company's assets, and enter into certain transactions with affiliates.

7. Debt (Continued)

Debt obligations (continued)

The occurrence of events involving the Company or certain of the Company's subsidiaries may constitute an event of default under the
indenture. Such events include failure to pay interest, principal, or the premium on the Senior Notes when due; failure to comply with the merger, asset sale or change of control covenants; certain
defaults on other indebtedness; and certain insolvency proceedings. In the case of an event of default, the holders of the Senior Notes are entitled to remedies, including the acceleration of payment
of the Senior Notes by request of the holders of at least 25% in aggregate principal amount of the Senior Notes, and any action by the trustee to collect payment of principal, interest or premium in
arrears.

Niska
Partners has the option to prepay the Senior Notes. Prior to March 15, 2013, the Niska Partners may redeem up to 35% of the aggregate principal amount of the Senior Notes at
a premium, plus accrued and unpaid interest with net cash proceeds of certain equity offerings. Prior to March 15, 2014, the Company may redeem some or all of the Senior Notes at a
make-whole premium, as set forth in the offering memorandum. After March 15, 2014, the Company may redeem some or all of the Senior Notes at a premium that will decrease over time
until maturity.

Revolving credit facilities

In March 2010, Niska Partners, through its subsidiaries, Niska Gas Storage US, LLC and AECO Gas Storage Partnership entered into
senior secured asset-based revolving credit facilities, consisting of a U.S. revolving credit facility and a Canadian revolving credit facility (the "Credit Facilities" or the "$400.0 million
Credit Agreement"). These Credit Facilities provide for revolving loans and letters of credit in an aggregate principal amount of up to $200.0 million for each of the U.S. revolving credit
facility and the Canadian revolving credit facility. Subject to certain conditions, each of the U.S. revolving credit facility and the Canadian revolving credit facility may be expanded up to
$100.0 million in additional commitments, and the commitments in each facility may be reallocated on terms and according to procedures to be determined. Loans under the U.S. revolving facility
will be denominated in U.S. dollars and loans under the Canadian revolving facility may be denominated, at Niska Partners' option, in either U.S. or Canadian dollars. Royal Bank of Canada is acting as
administrative agent and collateral agent for the revolving credit facilities. Each revolving credit facility matures on March 5, 2014.

Borrowings
under the Credit Facilities are limited to a borrowing base calculated as the sum of specified percentages of eligible cash and cash equivalents, eligible accounts receivable,
the net liquidating value of hedge positions in broker accounts, eligible inventory, issued but unused letters of credit, and certain fixed assets minus the amount of any reserves and other priority
claims. Borrowings will bear interest at a floating rate, which (1) in the case of U.S. dollar loans can be either LIBOR plus an applicable margin or, at Niska Partners' option, a base rate
plus an applicable margin, and (2) in the case of Canadian dollar loans can be either the bankers' acceptance rate plus an applicable margin or, at Niska Partners' option, a prime rate plus an
applicable margin. The credit agreement provides that Niska Partners may borrow only up to the lesser of the level of the then current borrowing base or the committed maximum borrowing capacity, which
is $400.0 million. As of March 31, 2011, the borrowing base collateral totaled $486.5 million.

7. Debt (Continued)

Revolving credit facilities (continued)

Obligations under the $400.0 million Credit Agreement are guaranteed by the Niska Partners' and all of the Company's direct and
indirect wholly owned subsidiaries (subject to certain exceptions) and secured by a lien on substantially all of the Company's and its direct and
indirect subsidiaries' current and fixed assets (subject to certain exceptions). Certain fixed assets will only be required to be part of the collateral to the extent such fixed assets are included in
the borrowing base under the Credit Facility. The aggregate borrowing base under the Credit Facilities includes $150.0 million (the "PP&E Amount") due to a first-priority lien on fixed assets
granted to the lenders. The PP&E Amount will be reduced on a dollar-for-dollar basis upon the release of fixed assets having a value in excess of $50.0 million from such
liens.

The
$400.0 million Credit Agreement contains limitations on Niska Partners' ability to pay distributions in respect of, repurchase or pay dividends on its membership interests (or
other capital stock) or make other restricted payments. These limitations are substantially similar to those contained in the indenture governing the Senior Notes. Under these limitations, the
$400.0 million Credit Agreement would have permitted the Company to distribute approximately $75 million as at March 31, 2011.

The
following fees are applicable under each revolving credit facility: (1) an unused line fee of 0.75% per annum, based on the unused portion of the respective revolving credit
facility; (2) a letter of credit participation fee on the aggregate stated amount of each letter of credit equal to the applicable margin for LIBOR loans or bankers' acceptance loans, as
applicable; and (3) certain other customary fees and expenses of the lenders and agents. The Company is required to make prepayments under the revolving credit facilities at any time when, and
to the extent that, the aggregate amount of the outstanding loans and letters of credit under such revolving credit facility exceeds the lesser of the aggregate amount of commitments in respect of
such revolving credit facility and the applicable borrowing base.

The
$400.0 million Credit Agreement contains customary covenants, including, but not limited to, restrictions on the Company's and its subsidiaries' ability to merge and
consolidate with other companies, incur indebtedness, grant liens or security interests on assets subject to security interests under the credit agreement, make acquisitions, loans, advances or
investments, pay distributions, sell or otherwise transfer assets, optionally prepay or modify terms of any subordinated indebtedness or enter into transactions with affiliates. The Credit Facilities
require the maintenance of a fixed charge coverage ratio of 1.1 to 1.0 at the end of each fiscal quarter when excess availability under both the U.S. revolving credit facility and the Canadian
revolving credit facility is less than 15% of the aggregate amount of availability under both revolving credit facilities. Such fixed charge coverage ratio will be tested at the end of each quarter
until such time as average excess availability exceeds 15% for thirty consecutive days.

The
$400.0 million Credit Agreement provides that, upon the occurrence of certain events of default, the Company's obligations thereunder may be accelerated and the lending
commitments terminated. Such events of default include payment defaults to the lenders, material inaccuracies of representations and warranties, covenant defaults, cross-defaults to other material
indebtedness, including the notes, voluntary and involuntary bankruptcy proceedings, material money judgments, material events relating to pension plans, certain change of control events and other
customary events of default.

As of March 31, 2011, no borrowings were outstanding under the Credit Facilities and the Company had $3.1 million in
letters of credit issued (March 31, 2010$3.5 million). The Company and its subsidiaries were in compliance with all covenant requirements.

Restrictions

Niska Partners has no independent assets or operations other than its investments in its subsidiaries. Both the Senior Notes and the
$400.0 million Credit Agreement have been jointly and severally guaranteed by Niska Partners and substantially all of its subsidiaries. Niska Partners' subsidiaries have no significant
restrictions on their ability to pay distributions or make loans to Niska Partners, which are prepared and measured on a consolidated basis, and have no restricted assets as of March 31, 2011.

8. Asset Retirement Obligations

Niska Partners' asset retirement obligations relate to plugging and abandonment of the storage facilities at the end of their estimated useful economic lives. At March 31, 2011,
the estimated undiscounted cash flows required to settle the asset retirement obligations are approximately $24.4 million, calculated using an inflation rate of 2% per annum. The estimated
liability at March 31, 2011 was $1.5 million after discounting the estimated cash flows at a rate of 8% per annum. At March 31, 2011, the expected timing of payment for settlement
of the obligations is 46 years.

The
Company is not a taxable entity. Income taxes on its income are the responsibility of individual unit holders and have accordingly not been recorded in the consolidated financial
statements. Niska Partners has Canadian corporate subsidiaries, which are taxable corporations subject to income taxes, which are included in the consolidated financial statements.

As
at March 31, 2011, Niska Partners Canadian subsidiaries had accumulated non-capital losses of approximately $27.5 million (March 31,
2010$55.8) million that can be carried forward and applied against future taxable income. These non-capital losses have resulted in deferred income tax assets of
$7.0 million (March 31, 2010$14.9 million). Additionally, Niska Partners' Canadian subsidiaries had recognized deferred income tax assets related to capital losses of
$91.1 million (March 31, 2010$137.8 million) at March 31, 2011. The capital losses represent $11.4 million
(March 31, 2010$17.2 million) of deferred tax assets, of which all have been fully offset by valuation allowances due to the uncertainty of their realization. Of the
total tax assets related to losses, $5.9 million will begin to expire at the end of 2029.

During
the period ended March 31, 2010, two of the Canadian subsidiaries of Niska Partners elected to adopt the US dollar as their currency to file their Canadian tax returns. As
a result of the currency
election, temporary differences pertaining to non-monetary items caused the deferred income tax liability and deferred income tax expense to increase by $22.5 million.

For
the years ended March 31, 2011, 2010 and 2009, Niska Partners had not recognized any amounts in respect of potential interest and penalties associated with uncertain tax
positions. The Company files income tax returns in the U.S. federal jurisdiction, various state jurisdictions and other foreign jurisdictions. The Company is subject to income tax examinations for the
fiscal years ended 2007 through 2011 in most jurisdictions.

Uncertain Income Tax Positions

When accounting for uncertainty in income taxes (ASC 740-10), a company recognizes a tax benefit in the financial
statements for an uncertain tax position if management's assessment is that the position is "more likely than not" (i.e. a likelihood greater than fifty percent) to be allowed by the tax
jurisdiction based solely on the technical merits of the position. The term "tax position" refers to a position in a previously filed tax return or a position expected to be taken in a future tax
return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods.

The following table indicates the changes to the Company's unrecognized tax benefits for the years ended March 31, 2011 and

statements. Interest and penalties are not included.

Approximately
one hundred percent of the $2.2 million of unrecognized tax benefits at March 31, 2011, would have an impact on the effective tax rate if subsequently
recognized.

The
Company engages in ongoing discussions with tax authorities regarding the resolution of tax matters in various jurisdictions. Both the outcome of these tax matters and the timing of
the resolution and/or closure of the tax audits are highly uncertain. However, it is reasonably possible that developments on tax matters in certain tax jurisdictions may result in a sixty percent
decrease of the Company's total unrecognized tax benefits within the next twelve months.

10. Risk Management Activities and Financial Instruments

Risk management overview

The Company has exposure to commodity price, foreign currency, counterparty credit, interest rate, and liquidity risk. Risk management
activities are tailored to the risk they are designed to mitigate.

Commodity price risk

As a result of its natural gas inventory, Niska Partners is exposed to risks associated with changes in price when buying and selling
natural gas across future time periods. To manage this risk and reduce variability of cash flows, the Company utilizes a combination of financial and physical derivative contracts, including forwards,
futures, swaps and option contracts. The use of these contracts is subject to the Company's risk management policies. Niska Partners has not elected hedge accounting treatment and therefore changes in
fair value are recorded directly into earnings.

Forwards
and futures are contractual agreements to purchase or sell a specific financial instrument or natural gas at a specified price and date in the future. The Company enters into
forwards and futures to mitigate the impact of price volatility. In addition to cash settlement, exchange traded futures may also be settled by physical delivery of natural gas.

(Thousands of U.S. dollars)

10. Risk Management Activities and Financial Instruments (Continued)

Commodity price risk (continued)

Swap contracts are agreements between two parties to exchange streams of payments over time according to specified terms. Swap
contracts require receipt of payment for the notional quantity of the commodity based on the difference between a fixed price and the market price on the settlement date. The Company enters into
commodity swaps to mitigate the impact of changes in natural gas prices.

Option
contracts are contractual agreements to convey the right, but not the obligation, for the purchaser of the option to buy or sell a specific physical or notional amount of a
commodity at a fixed price, either at a fixed date or at any time within a specified period. Niska Partners enters into option agreements to mitigate the impact of changes in natural gas prices.

To
limit its exposure to changes in commodity prices, Niska Partners enters into purchases and sales of natural gas inventory and concurrently matches the volumes in these transactions
with offsetting forward contracts. To be in compliance with its risk policy, Niska Partners is required to limit its exposure of unmatched volumes of proprietary current natural gas inventory to an
aggregate overall limit of 8.0 billion cubic feet ("Bcf"). As at March 31, 2011, 33.0 Bcf of natural gas inventory was offset, representing 99.4% of total current inventory.
Non-cycling working gas, which is included in long-term inventory, and fuel gas used for operating our facilities are excluded from the coverage requirement. Total volumes of
non-cycling working gas and fuel gas at March 31, 2011 were 3.4 Bcf and 0.0 Bcf, respectively.

Counterparty credit risk

Niska Partners is exposed to counterparty credit risk on its trade and accrued accounts receivable and risk management assets.
Counterparty credit risk is the risk of financial loss to the Company if a customer fails to perform its contractual obligations. Niska Partners engages in transactions for the purchase and sale of
products and services with major companies in the energy industry and with industrial, commercial, residential and municipal energy consumers. Credit risk associated with trade accounts receivable is
mitigated by the high percentage of investment grade customers, collateral support of receivables and the Company's ability to take ownership of customer-owned natural gas stored in its facilities in
the event of non-payment. It is Management's opinion that no allowance for doubtful accounts is required at March 31, 2011 on accrued and trade accounts receivable.

The
Company analyzes the financial condition of counterparties prior to entering into an agreement. Credit limits are established and monitored on an ongoing basis. Management believes
based on its
credit policies, that the Company's financial position, results of operations and cash flows will not be materially affected as a result of non-performance by any single counterparty.
Although the Company relies on a few counterparties for a significant portion of its revenues (Note 21), one counterparty making up 37% of gross optimization revenue is a physical natural gas
clearing and settlement facility which requires counterparties to post margin deposits which reduces the risk of default.

Exchange
traded futures and options comprise approximately 46% of Niska Partners' commodity risk management assets at March 31, 2011. These exchange traded contracts have minimal
credit exposure as the exchanges guarantee that every contract will be margined on a daily basis. In the event of any default, Niska Partners' account on the exchange would be absorbed by other
clearing members.

10. Risk Management Activities and Financial Instruments (Continued)

Counterparty credit risk (continued)

Because
every member posts an initial margin, the exchange can protect the exchange members if or when a clearing member defaults.

Included
in the fair value of energy contracts at March 31, 2011 are one to five year contracts to sell natural gas to customers in retail markets. Niska Partners has recorded a
reduction in the fair value of these contracts of $3.4 million at March 31, 2011 (March 31, 2010$4.9 million, March 31, 2009$ nil),
representing an estimate of the expected credit exposure from these counterparties over their contractual lives.

Interest rate risk

The Company assesses interest rate risk by continually identifying and monitoring changes in interest rate exposures that may adversely
impact expected future cash flows.
Upon the completion of the March 5, 2010 senior notes offering Niska Predecessor reduced its exposure to fluctuations in interest rates by retiring its variable interest rate term debt in favor
of the fixed interest rates under the senior notes agreements totaling $800.0 million. Prior to the settlement of the variable interest rate term debt, management entered into interest rate
swap and swaption agreements to manage fluctuations in cash flows resulting from interest rate risk. Under the terms of the interest rate swap or swaption agreements, Niska Predecessor received
variable interest rate payments and made fixed interest rate payments. Interest rate swaps or swaptions were not designated as accounting hedges and related gains (losses) were reported as a component
of interest expense. All interest rate swap and swaptions agreements were settled on March 5, 2010 in conjunction with the retiring of the term debt. The impact of the settlement of the
interest rate swap and swaption agreements resulted in a realized gain in the prior year of $0.8 million recorded to interest expense.

At
March 31, 2011, the Company was exposed to interest rate risk resulting from its variable rate revolving credit facilities, which can be drawn up to $400.0 million. At
March 31, 2011, as no balance was outstanding on the credit facilities, Niska Partners had no exposure to interest rate fluctuations; however future drawings will result in exposure to changes
in interest rates.

Niska
Partners had no interest rate swap or swaption agreements at March 31, 2011 and March 31, 2010. At March 31, 2009 the Company had three interest rate swap or
swaption agreements with a notional amount of $250.0 million and a fair value liability of $12.7 million and four interest rate swap or swaption agreements with an amortizing notional
amount of $84.9 million and a fair value liability of $1.7 million.

Liquidity risk

Liquidity risk is the risk that Niska Partners will not be able to meet its financial obligations as they become due. The Company's
approach to managing liquidity risk is to contract a substantial part of its facilities to generate constant cash flow and to ensure that it always has sufficient cash and credit facilities to meet
its obligations when due, under both normal and stressed conditions, without incurring unacceptable losses or damage to its reputation. See Note 7 for details of the Company's debt.

Foreign currency risk

Foreign currency risk is created by fluctuations in foreign exchange rates. As Niska Partners' Canadian subsidiaries conducts a portion
of their activities in Canadian dollars, earnings and cash flows are subject to currency fluctuations. The performance of the Canadian dollar relative to the US dollar could positively or negatively
affect earnings. Niska Partners is exposed to cash flow risk to the extent that Canadian currency outflows do not match inflows. Niska Partners enters into currency swaps to mitigate the impact of
changes in foreign exchange rates. The notional value of currency swaps as at March 31, 2011 was $142.8 million (March 31, 2010$148.5 million, March 31,
2009$67.0 million). These contracts expire on various dates between April 1, 2011 and August 1, 2014. Niska Partners did not elect hedge accounting treatment and
therefore changes in fair value are recorded directly into earnings.

The
carrying amount of cash and cash equivalents, margin deposits, trade receivables, accrued receivables, trade payables, accrued liabilities, and accrued cushion gas purchases reported
on the consolidated balance sheet approximate fair value. The fair value of debt is the estimated amount the Company would have to pay to transfer its debt, including any premium or discount
attributable to the difference between the stated interest rate and market rate of interest at the balance sheet date. Fair values are based on valuations of similar debt at the balance sheet date and
supported by observable market transactions when available. See Note 7 for disclosures regarding the fair value of debt.

Fair
values have been determined as follows for the Company's financial assets and liabilities that were accounted for or disclosed at fair value on a recurring basis as of
March 31, 2011 and March 31, 2010:

prior to the initial public offering and is not held by Niska Partners Management LLC at March 31, 2011.

12. Members' Equity

In connection with the closing of Niska Partners' IPO on May 17, 2010 and the Contribution Agreement, Sponsor Holdings exchanged its interests in Niska Predecessor for common and
subordinated units of, as well as a Managing Member's interest in, Niska Partners. Because this exchange was treated for accounting purposes as an exchange of interests under common control, the
exchange was treated similar to a pooling of interests and, accordingly, all amounts exchanged were recorded at historical cost. Therefore, the Partners' capital and retained earnings balances that
existed at May 17, 2010 were transferred to the Managing Member's interest, common units and subordinated units of Niska Partners. Immediately subsequent to this exchange, the IPO of 17,500,000
common units was completed.

12. Members' Equity (Continued)

Pursuant
to the Contribution Agreement, and as partial consideration for the contribution of 100% of its equity interests to Niska Predecessor, Sponsor Holdings held the right to receive
any common units not purchased pursuant to the 30-day option granted to the underwriters of the offering to purchase up to an additional 2,625,000 common units. Upon the close of business
on June 10, 2010, the 30-day option granted to the underwriters expired unexercised. Pursuant to the Contribution Agreement, 2,625,000 common units were issued to Sponsor Holdings
on June 11, 2010.

Summary of changes in Managing Member, Common, and Subordinated units:

Managing Member units

The managing member units are held by Niska Gas Storage Management LLC, (the "Managing Member" or the "Manager"), which has a 2%
managing member interest in Niska Partners. The operating agreement provides that, during the subordination period, the managing member interest entitles the Manager the right to receive distributions
of Available Cash (as defined in the operating agreement) each quarter.

The
Manager has sole responsibility for conducting the Company's business and for managing its operations. Pursuant to the operating agreement, the Manager has delegated the power to
conduct Niska Partners' business and manage its operations to the Company's board of directors, all of the members of which are appointed by the Manager.

The
Manager has agreed not to withdraw voluntarily prior to March 31, 2020 subject to certain conditions outlined in the operating agreement. Prior to that time, the Manager may
not be removed unless that removal is approved by the vote of the holders of not less than 662/3% of the outstanding units, voting together as a single class, including units held by
the Manager and its affiliates. Any removal of the Manager is also subject to the approval of a successor manager by the vote of the holders of a majority of the outstanding common units and
subordinated units, voting as separate classes. The ownership of more than 331/3% of the outstanding units by the Manager and its affiliates gives them the ability to prevent the
Manager's removal. At March 31, 2011, Sponsor Holdings, which is an affiliate of the Manager, owned approximately 72.6% of the outstanding common and subordinated units. At any time, the owners
of the Manager may sell or transfer all or part of their ownership interests in the Manager to an affiliate or a third-party without the approval of the unitholders.

12. Members' Equity (Continued)

Common units

The common units are a class of non-managing membership interests in Niska Partners. The holders of the common units are entitled to
participate in the Company's distributions and exercise the rights and privileges available to members under the Company's operating agreement. The operating agreement provides that, during the
subordination period, the common unitholders have the right to receive distributions of Available Cash (as defined in the operating agreement) each quarter in an amount equal to $0.35 per common unit
(the "Minimum Quarterly Distribution"), plus any arrearages in the payment of the Minimum Quarterly Distribution.

Subordinated units

All of the subordinated units are held by Sponsor Holdings. The operating agreement provides that, during the subordination period, the
common unitholders have the right to receive the Minimum Quarterly Distribution, plus any arrearages in the payment of the Minimum Quarterly Distribution on the common units from prior quarters,
before any distributions of Available Cash may be made on the subordinated units. Furthermore, no arrearages will be paid on the subordinated units. The practical effect of the subordinated units is
to increase the likelihood that during the subordination period there will be Available Cash to be distributed on the common units. The subordination period will end on the second business day after
among other things, Niska Partners has earned and paid at least the Minimum Quarterly Distribution on each outstanding limited partner unit and Managing Member's unit for any consecutive twelve
quarters, ending on or after March 31, 2013. The subordination period also will end upon the removal of the Managing Member other than for cause if the units held by the Managing Member and its
affiliates are not voted in favor of such removal. When the subordination period ends, all remaining subordinated units will convert to common units, on a one-for-one basis,
and the common units will no longer be entitled to arrearages.

Long term equity-based incentives

In conjunction with the IPO, Niska Partners adopted the Niska Gas Storage Partners LLC 2010 Long Term Incentive Plan (the
"Plan") to provide additional compensation for employees, consultants and directors and to align their economic interest with those of common unitholders. The Plan is administered by the compensation
committee of the board of directors. The Plan currently permits the grant of unit awards, restricted units, phantom units, unit options, unit appreciation rights, other unit-based awards,
distribution equivalent rights and substitution awards covering an aggregate of 3,380,474 units. There have been no common units
granted since the inception of the plan. Please refer to Note 22 for a description of the grant of phantom unit awards issued subsequent to year-end.

Incentive distribution rights

Sponsor Holdings holds the incentive distribution rights. The following table illustrates the percentage allocations of cash
distributions from operating surplus between the unitholders, the Managing Member and the holders of incentive distribution rights, or based on the specified target distribution levels. The amounts
set forth under "Marginal Percentage Interest in Cash Distributions" are the percentage interests of the Managing Member, the incentive distribution right holders and the unitholders in any cash
distributions from operating surplus Niska Partners distributes up to and

To
the extent these incentive distributions are made to Sponsor Holdings, there will be more Available Cash proportionately allocated to Sponsor Holdings than to holders of common and
subordinated units.

Within
45 days after the end of each quarter Niska Partners will make cash distributions to the members of record on the applicable record date. Niska Partners distributed
$64.7 million to the holders of common and subordinated units and the Managing Member during the year ended March 31, 2011.

Unit-based compensation plan

Niska Predecessor had a long-term incentive plan under which the Board of Directors of could issue Class B and
Class C non-voting units to directors, officers and employees. The plans were liability-classified unit-based compensation awards which had both a service condition and
performance condition.

The
units vested 30%, 30% and 40%, respectively, on each successive anniversary following the grant-date, subject to certain service and performance conditions. Half of the
annual vesting was achieved when the annual defined performance targets were met, and the remaining annual vesting resulted from the unitholder remaining employed with Niska Predecessor through that
anniversary date. The service and performance conditions were met on May 12, 2009. The units had no expiry date provided the employee remained employed with Niska Predecessor.

On
March 5, 2010, the B and C units were conveyed to Niska Sponsor Holdings Coöperatif U.A. and Niska Gas Storage Canada GP, LLC through a series of
internal restructuring transactions. The units were allocated at a nominal value upon distribution.

As
at March 31, 2011, no compensation expense or liability has been recorded related to the Class B and C units.

The
B and C unitholders are not allocated a share in the distributions paid by Niska Partners.

17. Commitments and Contingencies

Contingencies

The Company and its subsidiaries are subject to various legal proceedings and actions arising in the normal course of business. While
the outcome of such legal proceedings and actions cannot be predicted with certainty, it is the opinion of Management that the resolution of such proceedings and actions will not have a material
impact on the Company's consolidated financial position or results of operations.

Commitments

Niska Partners has entered into non-cancelable operating leases for office space, leases for land use rights at its
operating facilities, storage capacity at other facilities, equipment, and vehicles used in its operations. The remaining lease terms expire between December 2011 and August 2056 and provide for the
payment of taxes, insurance and maintenance by the lessee. A renewal option exists on the office space lease to extend the term for another five years, exercisable prior to the termination of the
original lease.

The
related future minimum lease payments at March 31, 2011 were as follows:

20. Segment Disclosures

The Company's process for the identification of reportable segments involves examining the nature of services offered, the types of customer contracts entered into and the nature of the
economic and regulatory environment.

Niska
Partners operates along functional lines in its commercial, engineering, and operations teams for operations in Alberta, Northern California, and the U.S. Midcontinent. All
functional lines and facilities offer the same services: firm storage contracts, short-term firm services, and optimization. All services are delivered using reservoir storage. The Company
measures profitability consistently along all functional lines based on revenues and earnings before interest, taxes, depreciation and amortization, before unrealized risk management gains and losses.
The Company has aggregated its operating segments into one reportable segment as at and for the years ending March 31, 2011, March 31, 2010, and March 31, 2009.

Information
pertaining to the Company's short term and long term contract services and net optimization revenues is presented on the consolidated statements of earnings and comprehensive
income. All facilities have the same types of customers: major companies in the energy industry, industrial, commercial, and local distribution companies, and municipal energy consumers.

21. Economic Dependence

Niska Partners' exposure to the volume of business transacted with a natural gas clearing and settlement facility is described in Note 10. While the clearing and settlement
facility is its direct counterparty, its risk exposure to dependence on this counterparty is mitigated through the large number of members of the clearing and settlement facility who create the demand
for these transactions.

During
2011, Niska Partners did not have any other customers comprise greater than 10% of total revenue (2010none, 2009none).

22. Subsequent Events

Distributions

Subsequent to year end Niska Partners declared and paid distributions to its common and subordinated unitholders totaling
$24.1 million.

Compensation plans

a)    Long
Term Incentive Plan

Effective
April 1, 2011, the Company implemented two compensatory plans for its employees and certain service providers. The Niska Gas Storage
Partners LLC Phantom Unit Performance Plan (the "PUPP") was designed to further align the interests of participants in the PUPP, including the Company's named executive officers, with the
interest of the Company's unit holders by providing certain employees and directors with a phantom unit award. A "Phantom Unit" is a notional unit

22. Subsequent Events (Continued)

granted
under the PUPP that represents the right to receive a cash payment equal to the fair market value of a unit of the Company's common units, following the satisfaction of certain time periods
and/or certain performance criteria. The PUPP will be primarily administered by the Compensation Committee of the Board (the "Committee") and will grant Phantom Units to eligible participants at such
times as the Committee may determine to be appropriate.

Phantom
Units will generally be granted unvested and subject to both time and performance conditions. The default time period over which the Phantom Unit will vest will be three years
from the date of grant, and the performance measure will based upon distributed cash flow ("DCF") and total unitholder return ("TUR") metrics compared to such metrics at a select group of peer
companies to the Company. The DCF and TUR metrics are calculated based on the Company's percentile ranking during the applicable performance period compared to a peer group that will be determined by
the Committee from time to time. Provided that the Company has satisfied its minimum quarterly distribution targets for the underlying units, the Phantom Units will vest variably according to the
Company's performance relative to its peer group.

Effective
April 1, 2011, the Company issued 518,425 of the 3,380,474 Phantom units authorized.

b)    Short
Term Incentive Plan

Effective
April 1, 2011 the Company implemented the framework of a new short term incentive bonus plan applicable to Company employees (the "STI"). The
STI will provide annual bonuses based upon the achievement of Company performance targets, as well as individual performance targets for certain employees, as determined by the Company.

The
Company performance metric is a combination of certain financial and non-financial measures. The financial target will comprise eighty percent (80%) of the Company
performance
component, but the Committee may make adjustments to that target throughout the year as determined appropriate upon the advice of the management team. The remaining twenty percent (20%) of the
Company STI component will be comprised of certain non-financial measures. In addition to these criteria, payout of the STI is also subject to the Company's satisfaction of the quarterly
distribution threshold that the Company has set for its Units. If the Company achieves 75% to 120% of the Company performance measures for the year, the payout of the Company component of the STI will
equal 50% to 200%, respectively. However, if the Company's financial target is not also achieved at the minimum threshold for the year, no portion of the STI award will be paid out for
