SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the accompanying prospectus supplement may contain or incorporate by reference information that includes or is based upon "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Exchange Act. Forward-looking statements give expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. They use words such as "anticipate," "estimate," "expect," "project," "intend," "plan," "believe," and other words and terms of similar meaning in connection with a discussion of future operating or financial performance. In particular, these include statements relating to future actions, prospective services or products, future performance or results of current a nd anticipated services or products, exploration efforts, expenses, the outcome of contingencies such as legal proceedings, trends in operations and financial results.

Any or all forward-looking statements may turn out to be wrong. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. Many such factors will be important in determining our actual future results. These statements are based on current expectations and the current economic environment. They involve a number of risks and uncertainties that are difficult to predict. These statements are not guarantees of future performance, and there are no guarantees about the performance of any securities offered by this prospectus. Actual results could differ materially from those expressed or implied in the forward-looking statements. Among factors that could cause actual results to differ materially are:

the risk factors discussed in this prospectus or listed from time to time in prospectus supplements or any document we incorporate by reference;

changes in general economic conditions, including the performance of financial markets and interest rates;

changes in industry trends;

changes in laws or regulations; and

other factors, most of which are beyond our control.

We do not undertake any obligation to publicly correct or update any forward-looking statement if we later become aware that it is not likely to be achieved. You are advised, however, to consult any further disclosures we make on related subjects in reports filed with the SEC.

QUESTAR MARKET RESOURCES, INC.

The Company

Questar Market Resources, Inc. is a natural gas-focused energy company, a wholly owned subsidiary of Questar Corporation (Questar) and Questar's primary growth driver. We are a subholding company with three major lines of business – gas and oil exploration and production, midstream field services, and energy marketing – which are conducted through our four principal subsidiaries:

Questar Exploration and Production Company (Questar E&P) acquires, explores for, develops and produces natural gas, oil and natural gas liquids (NGL);

Wexpro Company (Wexpro) manages, develops and produces cost-of-service reserves for gas utility affiliate Questar Gas Company (Questar Gas);

Questar Gas Management Company (Gas Management) provides midstream field services including natural gas-gathering and processing services for affiliates and third parties; and

Questar Energy Trading Company (Energy Trading) markets equity and third-party gas and oil, provides risk-management services, and owns and operates an underground gas-storage reservoir.

We operate in the Rocky Mountain and Midcontinent regions of the United States of America and are headquartered in Salt Lake City, Utah. Principal offices are located in Denver, Colorado; Oklahoma City, Oklahoma; Tulsa, Oklahoma; and Rock Springs, Wyoming.

Exploration and Production – Questar E&P and Wexpro

General:

Our exploration and production business is conducted through Questar E&P and Wexpro. Questar E&P and Wexpro generated approximately 82% of our operating income in 2009. Questar E&P operates in two core areas - the Rocky Mountain region of Wyoming, Utah, Colorado and North Dakota and the Midcontinent region of Oklahoma, Texas and Louisiana. Questar E&P has a large inventory of identified development drilling locations, primarily on the Pinedale Anticline in western Wyoming and in northwestern Louisiana. Questar E&P continues to conduct exploratory drilling to determine the commerciality of its inventory of undeveloped leaseholds. Questar E&P seeks to acquire, develop and produce natural gas and oil from so-called "resource plays" in its core areas. Resource plays are characterized by continuous, aerially extensive hydrocarbon accumulations in tight sand, shale and coal reservoirs. Since the existence and distribution of hydrocarbons in resource plays is well understood, development of these accumulations has lower exploration risk than conventional discrete hydrocarbon accumulations. Resource plays typically require many wells, drilled at high density, to fully develop and produce. Development of resource play accumulations requires expertise in drilling large numbers of complex, highly deviated or horizontal development wells to depths in excess of 13,000 feet and application of advanced well stimulation techniques including hydraulic fracture stimulation to achieve economic production. Questar E&P seeks to maintain geographical and geological diversity with its two core areas. Questar E&P has in the past and may in the future pursue acquisition of producing properties through the purchase of assets or corporate entities to expand its presence in its core areas or create a new core area.

Questar E&P reported 2,746.9 Bcfe of estimated proved reserves as of December 31, 2009. Approximately 60% of Questar E&P's proved reserves, or 1,646.4 Bcfe, were located in the Rocky Mountain region of the United States, while the remaining 40%, or 1,100.5 Bcfe, were located in the Midcontinent region. Approximately 1,342.8 Bcfe of the proved reserves reported by Questar E&P at year-end 2009 were developed, while 1,404.1 Bcfe were categorized as proved undeveloped. Natural gas comprised about 92% of Questar E&P's total proved reserves at year-end 2009.

Wexpro manages, develops and produces cost of service reserves for gas utility affiliate Questar Gas under the terms of the Wexpro Agreement, a long-standing comprehensive agreement with the states of Utah and Wyoming. Pursuant to the Wexpro Agreement, Wexpro recovers its costs and receives an unlevered after-tax return of approximately 19-20% on its investment base. Wexpro's investment base is its investment in commercial wells and related facilities adjusted for working capital and reduced for deferred income taxes and depreciation. The term of the Wexpro Agreement coincides with the productive life of the gas and oil properties covered therein. Wexpro's investment base totaled $431.9 million at December 31, 2009.

Wexpro delivers natural gas production to Questar Gas at a price equal to Wexpro's cost-of-service. Cost-of-service gas satisfied 51% of Questar Gas supply requirements during 2009. Wexpro sells crude-oil production from oil-producing properties at market prices. Wexpro recovers operating expenses and a return on investment from crude-oil sales. Any residual operating income after recovery of operating expenses and return on investment is shared, with Questar Gas receiving 54% and Wexpro retaining 46%.

Wexpro's cost of service operations are contractually limited to a finite set of properties set forth in the Wexpro Agreement. Advances in technology (increased density drilling and multi-stage hydraulic fracture stimulation) have identified significant unexploited potential on many of the subject properties. Wexpro has identified over $1 billion of additional drilling opportunities that could support high single-digit to low double-digit growth in revenues and net income over the next five to ten years while delivering cost-of-service natural gas supplies to Questar Gas at prices competitive with alternative sources.

Competition and Customers:

Questar E&P faces competition in every part of its business, including the acquisition of producing properties and leasehold acreage, the marketing of gas and oil, and obtaining goods, services and labor. Its longer-term growth strategy depends, in part, on its ability to purchase reasonably-priced reserves and develop them in a low-cost and efficient manner.

Questar E&P, both directly and through Energy Trading, sells natural gas production to a variety of customers, including gas-marketing firms, industrial users and local-distribution companies. However, Questar E&P and Energy Trading do not sell natural gas to Questar Gas. Questar E&P regularly evaluates counterparty credit and may require financial guarantees from parties that fail to meet its credit criteria.

In 2009, 93% of Wexpro's revenues were from affiliated companies, primarily Questar Gas.

Regulation:

Questar E&P and Wexpro operations are subject to various government controls and regulation at the federal, state and local levels. Questar E&P must obtain permits to drill and produce; maintain bonding requirements to drill and operate wells; submit and implement spill-prevention plans; and file notices relating to the presence, use, and release of specified contaminants incidental to gas and oil production. Questar E&P is also subject to various conservation matters, including the regulation of the size of drilling and spacing units, the number of wells that may be drilled in a unit and the unitization or pooling of gas and oil properties. Wexpro gas- and oil-development and production activities are subject to the same type of regulation as Questar E&P. In addition, the Utah Division of Public Utilities has oversight responsibility and retains an outside reservoir-engineering consultant and a financial auditor to assess the prudence of Wexpro's activ ities.

Most Questar E&P leasehold acreage in the Rocky Mountain area is held under leases granted by the federal government and administered by federal agencies, principally the Bureau of Land Management (BLM). Current federal regulations restrict activities during certain times of the year on significant portions of Questar E&P leasehold due to wildlife activity and/or habitat. Questar E&P has worked with federal and state officials in Wyoming to obtain authorization for limited winter-drilling activities on the Pinedale Anticline and has developed measures, such as drilling multiple wells from a single pad location, to minimize the impact of its activities on wildlife and wildlife habitat. Various wildlife species inhabit Questar E&P leaseholds at Pinedale and in other areas. The presence of wildlife, including species that are protected under the federal Endangered Species Act could limit access to leases held by Questar E&P on public lands.

In September 2008, the BLM issued a Record of Decision (ROD) on the Final Supplemental Environmental Impact Statement for long-term development of natural gas resources in the Pinedale Anticline Project Area (PAPA). Under the ROD, Questar E&P and Wexpro are allowed to drill and complete wells year-round in one of five Concentrated Development Areas defined in the PAPA. The ROD contains additional requirements and restrictions on development of the PAPA.

Midstream Field Services – Questar Gas Management

General:

Gas Management generated approximately 16% of our operating income in 2009. Gas Management owns 78% of Rendezvous Gas Services, a partnership that operates gas-gathering facilities in western Wyoming. Rendezvous gathers natural gas for Pinedale Anticline and Jonah field producers for delivery to various interstate pipelines. Gas Management also owns 38% of Uintah Basin Field Services, LLC and 50% of Three Rivers Gathering, LLC partnerships that operate gas-gathering facilities in eastern Utah. The FERC-regulated Rendezvous Pipeline Co., LLC, a wholly owned subsidiary of Gas

Management, operates a 21-mile 20-inch-diameter pipeline between Gas Management's Blacks Fork gas-processing plant and the Muddy Creek compressor station owned by Kern River Gas Transmission Co. (Kern River Pipeline).

Fee-based gathering and processing revenues were 81% of Gas Management's net operating revenues (revenues less plant shrink) during 2009. Approximately 42% of Gas Management's 2009 net gas-processing revenues (processing revenues less plant shrink) were derived from fee-based processing agreements. The remaining revenues were derived from keep-whole processing agreements. A keep-whole contract exposes Gas Management to frac-spread risk while a fee-based contract eliminates commodity price exposure. To further reduce volatility associated with keep-whole contracts, Gas Management may enter into forward-sales contracts for NGL or hedge NGL prices and equivalent gas volumes with the intent to lock in a processing margin. Under a contract with Questar Gas, Gas Management also gathers cost-of-service volumes produced from properties operated by Wexpro.

In 2009, 10% of Gas Management's revenues were from affiliated companies, primarily Questar Gas.

Competition and Customers:

Gas Management provides natural gas-gathering and processing services to affiliates and third-party producers who have proved and/or producing gas fields in the Rocky Mountain region. Most of Gas Management’s gas-gathering and processing services are provided under long-term agreements.

Energy Marketing – Questar Energy Trading

General:

Energy Trading markets natural gas, oil and NGL and generated approximately 2% of our operating income in 2009. It combines gas volumes purchased from third parties and equity production to build a flexible and reliable portfolio. As a wholesale marketing entity, Energy Trading concentrates on markets in the Rocky Mountains, Pacific Northwest and Midcontinent that are either close to affiliate reserves and production or accessible by major pipelines. Energy Trading contracts for firm-transportation capacity on pipelines and firm-storage capacity at Clay Basin, a large baseload-storage facility owned by affiliate Questar Pipeline Company. Energy Trading, through its subsidiary Clear Creek Storage Company, LLC, operates an underground gas-storage reservoir in southwestern Wyoming. Energy Trading uses owned and leased storage capacity together with firm-transportation capacity to take advantage of price differentials and arbitrage opportunit ies.

Competition and Customers:

Energy Trading sells Questar E&P crude-oil production to refiners, remarketers and other companies, including some with pipeline facilities near company producing properties. In the event pipeline facilities are not available, Energy Trading transports crude oil by truck or rail to storage, refining or pipeline facilities. Energy Trading uses derivative instruments to manage commodity price risk. Energy Trading primarily uses fixed-price swaps to secure a known price for a specific volume of production. Energy Trading does not engage in speculative hedging transactions.

Employees

At December 31, 2009, we had 905 employees compared with 907 a year earlier.

Principal Executive Offices

Our principal executive offices are located at 180 East 100 South, P.O. Box 45601, Salt Lake City, UT 84145-0601 and our telephone number is (801) 324-2600.

RISK FACTORS

Investment in any securities offered pursuant to this prospectus involves risks. You should carefully consider the risk factors contained in this prospectus and incorporated by reference to our most recent Annual Report on Form 10-K, any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K that we have filed or will file, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement before acquiring any of such securities. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. Please also refer to the section above entitled "Special Note Regarding Forward-Looking Statements."

RISKS RELATED TO THE DEBT SECURITIES

If an active trading market does not develop for a series of debt securities sold pursuant to this prospectus, you may be unable to sell any such debt securities. Unless otherwise specified in an accompanying prospectus supplement, any debt securities sold pursuant to this prospectus and the accompanying prospectus supplement will be new securities for which there currently is no established trading market. We may elect not to list any debt securities on a national securities exchange. While the underwriters of a particular offering of debt securities may advise us that they intend to make a market in those debt securities, the underwriters will not be obligated to do so and may stop their market making at any time. No assurance can be given:

that a market for any series of debt securities will develop or continue;

as to the liquidity of any market that does develop; or

as to your ability to sell any debt securities you may own or the price at which you may be able to sell your debt securities.

Our credit ratings may not reflect all the risks of an investment in the debt securities. Our credit ratings are an independent assessment of our ability to pay debt obligations. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of debt securities sold pursuant to this prospectus. Our credit ratings, however, may not reflect the potential impact of risks related to structural, market or other factors discussed in this prospectus on the value of your debt securities.

Because we are a holding company, our ability to pay our debts depends upon the ability of our subsidiaries to pay dividends and to advance funds. In addition, our ability to participate in any distribution of our subsidiaries’ assets is generally subject to the prior claims of the subsidiaries’ creditors. Because we conduct our business primarily through our subsidiaries, our ability to pay our debts depends upon the earnings and cash flow of our subsidiaries and their ability to pay dividends and advance funds. Contractual and legal restrictions applicable to our subsidiaries could limit our ability to obtain cash from them. Our rights to participate in any distribution of our subsidiaries’ assets upon their liquidation, reorganization or insolvency generally would be subject to the prior claims of the subsidiaries’ creditors. As a result, any debt securities we may issue will be structurally subordinated to the indebte dness and other liabilities of our subsidiaries.

Our ability to redeem debt securities may adversely affect your return on the debt securities. If debt securities sold pursuant to this prospectus are redeemable at our option or subject to mandatory redemption, we may, in the case of optional redemption, or must, in the case of mandatory redemption, choose to redeem the debt securities at times when prevailing interest rates may be relatively low. Accordingly, you will not be able to reinvest the redemption proceeds in a comparable security at an interest rate as high as that of the debt securities.

If we undergo a change of control, we may not have the ability to raise the funds necessary to finance the change of control offer required by the indenture governing the debt securities. Upon the occurrence of a change of control, holders of the debt securities will have the right to require us to purchase all or any part of such holders’ debt securities. There can be no assurance that we would have sufficient financial resources available to satisfy all of our obligations in the event of a change in control. Even if sufficient funds were otherwise available, the terms of our current and/or future debt instruments may prohibit our prepayment of debt securities before their scheduled maturity. Consequently, if we are not able to prepay the indebtedness under such debt instruments or obtain requisite consents, we will be unable to fulfill our repurchase obligations if holders of debt securities exercise their repurchase rights following a change of control, resulting i n an event of default

under the indenture. An event of default under the indenture may result in a default under our current and/or future debt instruments. See "Description of Debt Securities - Change of Control."

USE OF PROCEEDS

Unless otherwise set forth in a prospectus supplement, we plan to use the net proceeds from the sale of the securities by this prospectus to repay debt and to finance certain capital expenditures as well as for general corporate purposes, including working capital.

RATIO OF EARNINGS TO FIXED CHARGES

Our ratio of earnings to fixed charges for the periods indicated is stated below. For purposes of this presentation, earnings represent income before income taxes adjusted for fixed charges, earnings and distributions of equity investees. Income before income taxes includes our share of pretax earnings of equity investees. Fixed charges consist of total interest charges (expensed and capitalized), amortization of debt issuance costs and losses from reacquired debt, and the interest portion of rental expense estimated at 50%.


	Year Ended December 31
	2009	2008	2007	2006	2005
Ratio of Earnings to Fixed Charges⁽¹⁾	7.3	14.1	18.9	17.0	13.8

⁽¹⁾ To the extent that the proceeds from any offering of debt securities registered on the registration statement of which this prospectus forms a part will be used to repay any of our outstanding debt and will change the ratio of earnings to fixed charges by ten percent or greater, the applicable prospectus supplement will include a pro forma ratio for the most recent fiscal year and the latest interim period, if applicable, showing the application of the proceeds.

DESCRIPTION OF DEBT SECURITIES

General

The debt securities that we may sell from time to time will be issued under an indenture dated as of March 1, 2001 as amended and modified from time to time, between us and Wells Fargo Bank, N.A., as trustee. The following description is only a summary of the material provisions of the indenture. This summary description is not meant to be a complete description of the debt securities. However, this prospectus, any accompanying prospectus supplement and any free writing prospectus will contain the material terms of the securities being offered. We have filed the indenture as an exhibit to the registration statement of which this prospectus forms a part and you may inspect it at the office of the trustee. When we refer to securities, we refer to all debt securities that we have issued or may issue in the future under the indenture. All of our debt securities of one series need not be issued at the same time, and unless otherwise provided, a series may be reopened for issuance of additional debt securities without the consent of the holders of the debt securities of that series. All capitalized terms used, but not defined, in this section shall have the meanings set forth in the indenture.

Each prospectus supplement or any free writing prospectus will describe the terms relating to the specific series of debt securities being offered. These terms will include some or all of the following, among others:

the title of such debt securities;

any limit on the aggregate principal amount of such debt securities;

the price or prices at which we will sell such debt securities;

any other terms of such debt securities (which terms shall not be inconsistent with the provisions of the indenture).

If any particular terms of our debt securities, described in the prospectus supplement or any free writing prospectus, differ from any of the terms described in this prospectus, then those terms as set forth in the relevant prospectus supplement or free writing prospectus will control.

Unless otherwise specified in the applicable prospectus supplement, debt securities will not be listed on any securities exchange.

Unless otherwise specified in the applicable prospectus supplement, debt securities will be issued in fully-registered form without coupons.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. Debt securities may also be issued as indexed securities or securities denominated in foreign currencies, currency units or composite currencies, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

Ranking

The indenture provides for the issuance of securities in one or more series, without limitation as to aggregate principal amount and without the consent of the holders of any existing series of debt securities issued under the indenture. As a holding company with subsidiaries, the claims of creditors of our subsidiaries will have priority over the claims of holders of the debt securities. The debt securities will be our unsecured obligations and will rank equally with our other unsecured and unsubordinated indebtedness from time to time outstanding. The debt securities will be unsecured and, accordingly, the holders of any secured indebtedness we may incur will have prior claim to the extent of the value of assets securing such indebtedness.

Book Entry System

Unless an accompanying prospectus supplement states otherwise, the debt securities will be issued in the form of a single global security. The debt securities will be deposited with the trustee as custodian for The Depository Trust Company ("DTC") on behalf of DTC and for so long as DTC or its nominee is the registered owner of the debt securities, DTC or its nominee, as the case may be, will be considered the sole holder of the debt securities for all purposes under the indenture. Except as set forth below, a security may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC. We anticipate that the following provisions will apply to all depositary arrangements for debt securities represented by a registered global security.

Upon our issuance of the debt securities, DTC or its nominee will credit the accounts of persons holding through it on its book entry registration and transfer system with the respective principal amounts of the debt securities represented by the global security. The accounts to be credited will be designated by the applicable underwriters of such debt securities. Ownership of beneficial interests in the global security will be limited to persons who have accounts with DTC, called participants, or persons that hold interests through participants. Ownership of beneficial interests by participants in the global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee for the global security. Ownership of beneficial interest in a global security by persons that hold interests through participants will be shown on, and the transfer of ownership will be effected only through, records maintained by such participant. The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interest in a global security.

Except as provided below, owners of beneficial interests in debt securities represented by a global security will not be entitled to have debt securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of debt securities in definitive form, known as certificated debt securities, and will not be considered the owners or holders of such debt securities under the indenture.

Debt securities represented by a global security will be exchangeable for certificated debt securities only if:

DTC or its nominee notifies us that it is unwilling or unable to continue as depositary for the global security or we become aware that DTC has ceased to be a clearing agency registered under the Exchange Act and we have not appointed a successor depositary within 90 days after we receive such notice or become aware of such ineligibility; or

we, in our sole discretion, determine to discontinue use of the system of book entry transfer and to exchange the global security for certificated debt securities.

Upon any such exchange, the certificated debt securities will be registered in the names that DTC or its nominee holding the global security may direct.

We will make principal, premium and interest payments on the global security to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the debt securities represented thereby for all purposes under the indenture. DTC's practice is to credit participants' accounts on the applicable payment date in accordance with their respective holdings shown on DTC's records unless DTC has reason to believe that it will not receive payment on such date. We expect that payments by participants to owners of beneficial interests in a global security held through such participants will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such participant and not of DTC, the trustee or us, subject to any statutory or regulatory requirements as may be in effe ct from time to time. Payment of principal, premium and interest to DTC is our responsibility and that of the trustee, disbursement of such payments to participants is the responsibility of DTC, and disbursement of such payments to the owners of beneficial interests in a global security held through such participants is the responsibility of such participants. Neither we, the trustee, the Paying Agent or the Security Registrar, will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a global security representing any debt securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The debt securities will be issued as fully registered securities registered in the name of Cede & Co., DTC's partnership nominee. DTC is a limited purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold the securities of its participants and to facilitate the clearance and settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book entry changes in participants' accounts, thus eliminating the need for physical movement of securities certificates. Direct participants of DTC include securities br okers and dealers, including the underwriters, banks, trust companies, clearing corporations and certain other organizations, some of which are owners of DTC. Access to DTC's system is also available to others, known as indirect participants, such as securities brokers and dealers, banks and trust companies that clear through or maintain a direct or indirect custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Purchases of debt securities under DTC's system must be made by or through direct participants, which will receive a credit for such debt securities on DTC's records. The ownership interest of each actual purchaser, or beneficial owner, of each debt security represented by a global security is in turn to be recorded on the records of direct participants and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct participants or indirect participants through which such beneficial owner entered into the transaction. Transfer of ownership interests in the global security are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners of the global security will not receive certificated debt securities representing their ownership interests in the global security, except in the limited circumstances described above.

To facilitate subsequent transfers, the global security deposited with, or on behalf of, DTC is registered in the name of DTC's nominee, Cede & Co. The deposit of the global security with, or on behalf of, DTC and its registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the global security; DTC's records reflect only the identity of the direct participants to whose accounts debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. will consent or vote with respect to the debt securities. Under its usual procedures, DTC mails an omnibus proxy to us as soon as possible after the applicable record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose account the debt securities are credited on the applicable record date (identified in a listing attached to the omnibus proxy).

If applicable, redemption notices will be sent to Cede & Co. If less than all of the debt securities are being redeemed, DTC's practice is to determine by lot the amount of the interest of each direct participant in such issue to be redeemed.

No service charge will be made for the registration of transfer or exchange of debt securities, but we may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith. Debt securities may be surrendered for registration of transfer or exchange at our offices or agencies maintained for such purpose, which shall initially be the Corporate Trust Office of the trustee in Salt Lake City, Utah. In the event that certificated debt securities are issued or if DTC shall so require, we will be required to appoint a paying agent and security registrar in The City of New York. We may appoint additional paying agents and security registrars and may change any paying agent or security registrar, subject to our obligation under the indenture to maintain a paying agent and security registrar in Salt Lake City, Utah and in the event that certificated debt securities are issued or if DTC sha ll so require, The City of New York. At our option, payment of interest on certificated debt securities may be made by check mailed to the addresses of the persons entitled thereto as they appear on the security register.

Restrictive Covenant

Limitation on Liens. Subject to certain exceptions, we will not, and will not permit any subsidiary to, create, assume or suffer to exist, otherwise than in favor of us or a subsidiary, any mortgage, pledge, lien, encumbrance or security interest (collectively, "Liens") upon any of our properties or assets or upon any income or profits therefrom unless the debt securities shall be equally and ratably secured. This prohibition will not apply to:

Liens existing as of the date of the indenture;

any purchase money mortgage or Lien created to secure all or part of the purchase price of any property (or to secure a loan made to us or any subsidiary to enable us or it to acquire such property), provided that such Lien shall extend only to the property so acquired, improvements thereon, replacements thereof and the income or profits therefrom;

Liens on any property at the time of the acquisition thereof, whether or not assumed by us or a subsidiary; provided that such Lien shall extend only to the property so acquired, improvements thereon, replacements thereof and income or profits therefrom;

Liens on any property or any contract for the sale of any product or service, or any rights thereunder or any proceeds therefrom, acquired or constructed by us or a subsidiary and created within one year after the later of: (i) the completion of such acquisition or construction or (ii) the commencement of operation of the property, provided that such Lien shall extend only to the property so acquired or constructed, improvements thereon, replacements thereof and income or profits therefrom;

Liens on the property or assets of subsidiaries outstanding at the time they become subsidiaries;

Liens created or assumed by us or a subsidiary on coal, geothermal, oil, natural gas, inert gas, other hydrocarbon or mineral properties owned or leased by us or a subsidiary to secure loans to us or a subsidiary, for the purpose of developing such properties;

Liens on any investment (as defined in the indenture) of ours or that of a subsidiary of ours in any person other than a subsidiary or on any security representing any investment of ours or a subsidiary of ours;

any Lien not otherwise permitted by the indenture, provided that after giving effect to such Lien the sum of all indebtedness of us and our subsidiaries secured by Liens not otherwise permitted by the indenture and all Attributable Debt of us and our subsidiaries (to the extent not included in indebtedness secured by Liens not otherwise permitted) does not exceed 10% of Consolidated Capitalization;

any refunding or extension of maturity, in whole or in part, of any obligation or indebtedness secured by certain permitted Liens, provided that the principal amount of the obligation or indebtedness secured by such refunding or extension shall not exceed the principal amount of the obligation or indebtedness then outstanding and shall be limited in lien to the same or substituted property and after acquired property that secured the refunded or extended obligation or indebtedness;

Liens upon any office equipment, data processing equipment or any motor vehicles, tractors or trailers;

Liens of or upon or in current assets of ours or a subsidiary of ours created or assumed to secure indebtedness incurred in the ordinary course of business;

any Lien which is payable, both with respect to principal and interest, solely out of the proceeds of natural gas, oil, coal, geothermal resources, inert gas, hydrocarbons or minerals to be produced from the property subject thereto and to be sold or delivered by us or a subsidiary of ours;

Liens to secure indebtedness incurred to finance advances made by us or any subsidiary of ours to any third party for the purpose of financing oil, natural gas, hydrocarbon, inert gas or other mineral exploration or development, provided that such Liens shall extend only to our receivables or that of such subsidiary in respect of such advances;

any rights reserved in others to take or reserve any part of the natural gas, oil, coal, geothermal resources, inert gas, hydrocarbons or minerals produced at any time on any property of ours or a subsidiary of ours; and

Liens which secure indebtedness of a subsidiary of ours.

Also excepted from the general prohibition are various other liens, such as mechanics' or materialmen's liens, certain governmental liens, leases, certain judgment liens, and certain liens arising in connection with leases, easements and rights of way.

Unless an accompanying prospectus supplement or free writing prospectus states otherwise, the above restrictive covenant shall apply to each series of debt securities.

Change of Control

Unless an accompanying prospectus supplement states otherwise, if a Change of Control occurs and is accompanied by a Rating Decline (together, a "Change of Control Triggering Event"), each registered holder of debt securities will have the right to require us to offer to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such holder's debt securities at a purchase price in cash equal to the principal amount of the debt securities plus accrued and unpaid interest, if any, to the date of purchase.

Within 30 days following any Change of Control Triggering Event, we will mail a notice (the "Change of Control Offer") to each registered holder with a copy to the trustee stating:

(1) that a Change of Control Triggering Event has occurred and that such holder has the right to require us to purchase such holder's debt securities at a purchase price in cash equal to the principal amount of such debt securities plus accrued and unpaid interest, if any, to the date of purchase (the "Change of Control Payment");

(2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the "Change of Control Payment Date"); and

(3) the procedures determined by us, consistent with the indenture, that a holder must follow in order to have its debt securities repurchased.

On the Change of Control Payment Date, we will, to the extent lawful:

(1) accept for payment all debt securities or portions thereof (in integral multiples of $1,000) properly tendered and not withdrawn under the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all debt securities or portions thereof so tendered; and

(3) deliver or cause to be delivered to the trustee the debt securities so accepted together with an Officers' Certificate stating the aggregate principal amount of debt securities or portions thereof being purchased by us.

The paying agent will promptly mail to each holder of debt securities so tendered the Change of Control Payment for such debt securities, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new debt security equal in principal amount to any unpurchased portion of the debt securities surrendered, if any; provided that each such new debt security will be in a principal amount of $1,000 or an integral multiple of $1,000.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a debt security is registered at the close of business on such record date, and no additional interest will be payable to holders who tender pursuant to the Change of Control Offer.

Except as described above with respect to a Change of Control Triggering Event, the indenture does not contain provisions that permit the holders to require that we repurchase or redeem the debt securities in the event of a takeover, recapitalization or similar transaction.

Prior to mailing a Change of Control Offer, and as a condition to such mailing (i) the requisite holders of each issue of Indebtedness issued under any indenture or other agreement that may be violated by such payment shall have consented to such Change of Control Offer being made and waived the event of default, if any, caused by the Change of Control Triggering Event or (ii) we will repay all outstanding Indebtedness issued under any indenture or other agreement that may be violated by a payment to the holders of debt securities under a Change of Control Offer or we must offer to repay all such Indebtedness, and make payment to the holders of such Indebtedness that accept such offer and obtain waivers of any event of default from the remaining holders of such Indebtedness. We covenant to effect such repayment or obtain such consent and waiver within 30 days following any Change of Control Triggering Event, it being an Event of Default u nder the indenture if we fail to comply with such covenant within 30 days after receipt of written notice from the trustee or the holders of at least 25% in principal amount of the debt securities.

We will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by us and purchases all debt securities validly tendered and not withdrawn under such Change of Control Offer.

Our and our subsidiaries' current and/or future debt instruments may require that we repay or refinance indebtedness under such debt instruments in the event of a change of control, as defined in such debt instruments. Such change of control provisions may be triggered under such debt instruments prior to the occurrence of a Change of Control Triggering Event, thereby requiring that the indebtedness under such debt instruments be repaid or refinanced prior to our repurchasing any debt securities upon the occurrence of a Change of Control Triggering Event. Moreover, the exercise by the holders of their right to require us to repurchase the debt securities could cause a default under such debt instruments, even if the Change of Control Triggering Event itself does not, due to the financial effect of such repurchase on us. In such event, we may not be able to satisfy our obligations to repurchase the debt securities unless we are able to ref inance or obtain waivers with respect

to such debt instruments. Finally, our ability to pay cash to the holders upon a repurchase may be limited by our then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

Even if sufficient funds were otherwise available, the terms of our current and/or future debt instruments may prohibit our prepayment of debt securities before their scheduled maturity. Consequently, if we are not able to prepay the indebtedness under such debt instruments or obtain requisite consents, we will be unable to fulfill our repurchase obligations if holders of debt securities exercise their repurchase rights following a Change of Control Triggering Event, resulting in an Event of Default under the indenture. An Event of Default under the indenture may result in a default under our current and/or future debt instruments.

Definitions

Certain terms used in the indenture are defined and are used in this prospectus as follows:

"Attributable Debt" means, as of the date of determination, the present value of net rent for the remaining term of a capital lease, determined in accordance with generally accepted accounting principles in the United States ("GAAP"), which is part of a Sale and Leaseback Transaction (as defined), including any periods for which the lessee has the right to renew or extend the lease. For purposes of the foregoing, "net rent" means the sum of capitalized rental payments required to be paid by the lessee, other than amounts required to be paid by the lessee for maintenance, repairs, insurance, taxes, assessments, energy, fuel, utilities and similar charges. In the case of a capital lease which is terminable by the lessee upon the payment of a penalty, such net amount shall also include the amount of such penalty, but no rent shall be considered to be required to be paid under such lease subsequent to the first date upon which it may be so terminated.

"Change of Control" means the occurrence of any of the following:

(1) Questar or any of its affiliates ceases to own, directly or indirectly, beneficially or of record or otherwise, collectively more than 50% of the aggregate voting power of our voting stock (or its successor by merger, consolidation or purchase of all or substantially all of our assets);

(2) the sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our and our subsidiaries' assets, taken as a whole to any person or group (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) other than to Questar or any of its affiliates; or

(3) the adoption by our stockholders of a plan or proposal of our liquidation or dissolution. Although there is a limited body of case law interpreting the phrase "all or substantially all", there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of "all or substantially all" of the property or assets of a Person. As a result, it may be unclear as to whether a Change of Control Triggering Event has occurred and whether a holder of debt securities may require us to make an offer to repurchase the debt securities as described above.

"Consolidated Capitalization" means, without duplication, the sum of:

the principal amount of our Consolidated Funded Debt and that of our subsidiaries at the time outstanding,

the total capital represented by our capital stock and that of our subsidiaries at the time outstanding based, in the case of stock having par value, upon its par value, and in the case of stock having no par value, upon the value stated on our books,

the total amount of (or less the amount of any deficit in) our retained earnings and paid in capital and that of our subsidiaries,

reserves for deferred federal and state income taxes arising from timing differences, and

Attributable Debt, all as shown on our consolidated balance sheet, prepared in accordance with GAAP; provided that in determining our consolidated retained earnings and paid in capital, no effect shall be given to any unrealized write up or write down in the value of assets or any amortization thereof, except for accumulated provisions for depreciation, depletion, amortization and property retirement which shall have been created by charges made by us or any of our subsidiaries on our or their books.

"Consolidated Funded Debt" means our Funded Debt and that of our subsidiaries, consolidated in accordance with GAAP.

"Funded Debt" means all Indebtedness that will mature, pursuant to a mandatory sinking fund or prepayment provision or otherwise, and all installments of Indebtedness that will fall due, more than one year from the date of determination. In calculating the maturity of any Indebtedness, there shall be included the term of any unexercised right of the debtor to renew or extend such Indebtedness existing at the time of determination.

"Indebtedness" means all items of indebtedness for borrowed money (other than unamortized debt discount and premium) which would be included in determining total liabilities as shown on the liability side of a balance sheet prepared in accordance with GAAP as of the date as of which Indebtedness is to be determined, and shall include indebtedness for borrowed money (other than unamortized debt discount and premium) with respect to which we or any subsidiary of ours customarily pays interest secured by any mortgage, pledge or other lien or encumbrance of or upon, or any security interest in, any properties or assets owned by us or any subsidiary of ours, whether or not the Indebtedness secured thereby shall have been assumed, and shall also include guarantees of Indebtedness of others; provided that in determining our Indebtedness or that of any of our subsidiaries, there shall be included the aggregate liquidation preference of all outstanding se curities of any subsidiary senior to its Common Stock that are not owned by us or a subsidiary of ours; and provided, further, that Indebtedness of any Person shall not include the following:

any indebtedness evidence of which is held in treasury (but the subsequent resale of such indebtedness shall be deemed to constitute the creation thereof); or

any particular indebtedness if, upon or prior to the maturity thereof, there shall have been deposited with a depository (or set aside and segregated, if permitted by the instrument creating such indebtedness), in trust, money (or evidence of such indebtedness as permitted by the instrument creating such indebtedness) in the necessary amount to pay, redeem or satisfy such indebtedness; or

any indebtedness incurred to finance oil, natural gas, hydrocarbon, inert gas or other mineral exploration or development to the extent that the issuer thereof has outstanding advances to finance oil, natural gas, hydrocarbon, inert gas or other mineral exploration or development, but only to the extent such advances are not in default; or

any indebtedness incurred without recourse to us or any of our subsidiaries; or

any indebtedness incurred to finance advance payments for gas (pursuant to take or pay provisions or otherwise), but only to the extent that such advance payments are pursuant to gas purchase contracts entered into in the normal course of business; or

any amount (whether or not included in determining total liabilities as shown on the liability side of a balance sheet prepared in accordance with GAAP) representing capitalized rent under any lease; or

any indirect guarantees or other contingent obligations in respect of indebtedness of other Persons, including agreements, contingent or otherwise, with such other Persons or with third parties with respect to, or to permit or assure the payment of, obligations of such other Persons, including, without limitation, agreements to purchase or repurchase obligations of such other Persons, to advance or supply funds to, or to invest in, such other Persons, or to pay for property, products or services of such other Persons (whether or not conveyed, delivered or rendered); demand charge contracts, through put, take or pay, keep well, make whole or maintenance of working capital or similar agreements; or guarantees with respect to rental or similar periodic payments to be made by such other Persons.

"Moody's" means Moody's Investors Service or, if Moody's Investors Service shall cease rating debt securities having a maturity at original issue of at least one year and such ratings business shall have been transferred to a successor Person, such successor Person; provided, however, that if there is no successor Person, then "Moody's" shall mean any other national recognized rating agency, other than S&P, that rates debt securities having a maturity at original issuance of at least one year and that shall have been designated by us.

"Place of Payment" means, when used with respect to the debt securities, the place or places where the principal of (and premium, if any) and interest on the debt securities are payable as specified and contemplated by the indenture.

"Rating Agencies" means Moody's and S&P.

"Rating Date" means the earlier of the date of public notice of (i) the occurrence of a Change of Control or (ii) our intention to effect a Change of Control.

"Rating Decline" shall be deemed to have occurred if, no later than 90 days after the Rating Date (which period shall be extended so long as the rating of the debt securities is under publicly announced consideration for possible downgrade by either of the Rating Agencies), either of the Rating Agencies assigns a rating to the debt securities that is lower than an investment-grade rating. An investment-grade rating with respect to Moody's shall mean a rating of "Baa3" or higher and an investment grade rating with respect to S&P shall mean a rating of "BBB-" or higher.

"S&P" means Standard & Poor's Ratings Services or, if Standard & Poor's Ratings Services shall cease rating debt securities having a maturity at original issue of at least one year and such ratings business shall have been transferred to a successor Person, such successor Person; provided, however, that if there is no successor Person, then "S&P" shall mean any other national recognized rating agency, other than Moody's, that rates debt securities having a maturity at original issuance of at least one year and that shall have been designated by us.

"Sale and Leaseback Transaction" means an arrangement in which we or one of our subsidiaries sells any of our or their property which was placed into service more than 120 days prior to such sale to a Person and leases it back from that Person within 180 days of the sale.

"Stated Maturity" means, when used with respect to any debt security or any installment of principal thereof or interest thereon, the date specified in such debt security as the fixed date on which the principal of such debt security or such installment of principal or interest is due and payable.

Consolidation, Merger and Sale of Assets

Nothing contained in the indenture or in any of the debt securities will prevent any consolidation or merger of us with or into any other Person (whether or not affiliated with us), or successive consolidations or mergers in which we or our successor shall be a party, or will prevent any conveyance, transfer or lease of our property as an entirety or substantially as an entirety, to any other Person (whether or not affiliated with us); provided, however, that:

in case of such a transaction, the entity formed by such consolidation or into which we are merged, or the Person which acquires or leases our properties and assets substantially as an entirety shall be a corporation, partnership, limited liability company, association, company or business trust organized under the laws of the United States of America, any state thereof or the District of Columbia and shall expressly assume the due and punctual payment of the principal of, premium, if any, and interest on all the debt securities and the performance of every other covenant of the indenture;

immediately after giving effect to such transaction, no event which, after notice or lapse of time, would become an Event of Default, shall have occurred and be continuing; and

each of us and the successor Person shall have delivered to the trustee an Officers' Certificate and an Opinion of Counsel, each stating that such transaction complies with the requirements in the previous two paragraphs, and that all conditions precedent relating to such transaction have been complied with.

Events of Default

Unless an accompanying prospectus supplement or free writing prospectus states otherwise, the following are events of default with respect to the debt securities:

failure to pay the principal of, or premium, if any, on any debt security when due;

failure to pay any interest installment, or an additional amount, if any, on any debt security when due, in each case, continued for 30 days;

default in the deposit of any sinking fund payment, when and as due by the terms of a debt security, continued for 30 days;

failure to perform any of our other covenants, continued for 90 days after written notice as provided in the indenture;

the occurrence of an event of default in other indebtedness of ours (including securities other than the debt securities) which results in indebtedness in excess of $10,000,000 principal amount being due and payable prior to maturity, and such acceleration is not rescinded or annulled or such indebtedness is not discharged after written notice as provided in the indenture;

certain events of bankruptcy, insolvency or reorganization as described in the indenture; and

if applicable, the event of default described above relating to the terms of the indenture with respect to the holder’s right to require us to repurchase such debt securities if a Change of Control occurs and, if applicable, we fail to obtain consent of the requisite holders of each issue of other indebtedness that may be violated by making the Change of Control Payment.

If an event of default with respect to debt securities of any series at the time outstanding shall occur and be continuing, then in every such case the trustee or the holders of at least 33¹/3% in principal amount of the outstanding debt securities of such series may declare, by a notice in writing to us, and to the trustee if given by holders, the entire principal amount of all the outstanding debt securities of such series to be due and payable immediately. At any time after such a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of such series, by written notice to us and the trustee, may, in certain circumstances, rescind and annul such declaration.

No holder of any debt securities of any series will have any right to institute any proceeding with respect to the indenture or for any remedy under the indenture, unless such holder previously shall have given to the trustee written notice of a continuing event of default and unless also the holders of at least 25% of the aggregate principal amount of outstanding debt securities of such series shall have made written request to, and have offered reasonable indemnity upon, the trustee, to institute such proceeding, and the trustee shall not have received direction inconsistent with such request in writing by the holders of a majority in principal amount of outstanding debt securities of such series and shall have failed to institute such proceeding within 60 days. However, the rights of any holder of any debt securities to enforce the payment of principal, premium, if any, and interest due on such debt securities on or after the dates exp ressed in such debt securities may not be impaired or affected.

We must furnish the trustee within 120 days after the end of each fiscal year a statement signed by one of certain of our officers stating that a review of our activities during that year and our performance under the indenture and the terms of the debt securities has been made, and, to the best of the knowledge of the signatory, based on such review, we have complied with all conditions and covenants of the indenture, or, if we are in default, specifying the default.

Waiver, Modification and Amendment

The holders of a majority in principal amount of the outstanding debt securities of any series may waive certain past defaults, except a default in the payment of the principal of, premium, if any, or interest on any debt security of such series or in respect of any covenant or provision in the indenture that under the terms of the indenture cannot be modified without the consent of all holders of outstanding debt securities of such series affected. The holders of a majority in aggregate principal amount of outstanding debt securities may waive our compliance with certain restrictive provisions.

We and the trustee may modify and amend the indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities, provided that no such modification or amendment may, without the consent of the holder of each debt security affected thereby:

change the stated maturity of the principal of, or any installment of principal of or interest on any additional amounts with respect to, any debt security;

reduce the principal of, premium, if any, or interest on, or any additional amounts with respect thereto, or any premium payable upon the redemption of, any debt security;

change the place of payment or change the currency of payment of principal, premium, if any, or interest on, or any additional amounts with respect thereto, any debt security;

impair the right to institute suit for the enforcement of any payment on or with respect to any debt security;

reduce the percentages of holders of outstanding debt securities required to modify or amend the indenture or for any waiver provided for in the indenture;

change the provisions related to the Change of Control repurchase; or

effect certain other modifications or amendments described in the indenture.

In the case of provisions of the indenture affecting other series of securities as well as the debt securities, the holders of the debt securities will be treated as a separate class of securities for purposes of determining whether consent or waiver of a majority of holders has been obtained.

There are certain changes that we may make to the debt securities without a holder's specific approval and without any vote of the holders of the debt securities of the same series. Such changes are limited to clarifications and certain other changes that would not adversely affect the holders of the outstanding debt securities of such series in any material respect.

Defeasance and Covenant Defeasance

Unless an accompanying prospectus supplement or free writing prospectus states otherwise, we may elect either:

to defease and be discharged from our obligations with respect to the debt securities of any series ("defeasance"); or

to be released from our obligations with respect to debt securities of any series described above under "Limitations on Liens" and "Consolidation, Merger and Sale of Assets" ("covenant defeasance"), upon the irrevocable deposit with the trustee, in trust for such purpose, of money and/or U.S. Government Obligations (as defined in the indenture) that through the payment of principal and interest in accordance with their terms will provide money, in an amount sufficient to pay the principal of, premium, if any, and interest on such debt securities on the scheduled due date therefor.

Defeasance and covenant defeasance are each conditioned upon, among other things, our delivery to the trustee of an opinion of counsel to the effect that the holders of the debt securities will have no federal income tax consequences as a result of such deposit.

Notices

Notices to holders of the debt securities will be given by mail to the addresses of such holders as they appear in the security register.

Title

We or the trustee may treat the registered owner of any registered debt security as the owner thereof (whether or not the debt security shall be overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes.

Replacement of Debt Securities

We will replace any mutilated debt security at the expense of the holders upon surrender to the trustee. We will replace debt securities that become destroyed, lost or stolen at the expense of the holder upon delivery to the trustee of satisfactory evidence of the destruction, loss or theft thereof. In the event of a destroyed, lost or stolen debt security, an indemnity satisfactory to us and the trustee may be required at the expense of the holder of the debt security before a replacement debt security will be issued.

Governing Law

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Concerning the Trustee

Wells Fargo Bank, N.A. is the trustee under the indenture. The indenture contains certain limitations on the rights of the trustee, should it become a creditor of ours, to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions with us; however, if it acquires a conflicting interest, it must eliminate such conflict or resign or otherwise comply with the Trust Indenture Act of 1939, as amended. The indenture also provides that we will indemnify the trustee against loss, liability or expense incurred without negligence or bad faith on the part of the trustee arising out of or in connection with the trust under the indenture. Wells Fargo Bank, N.A. is a creditor of our parent company, Questar, and performs routine banking functions for us.

PLAN OF DISTRIBUTION

We may sell the debt being offered by this prospectus and any accompanying prospectus supplement or other offering materials:

to underwriters or dealers for resale to the public or to institutional investors;

directly to institutional investors; or

through agents to the public or to institutional investors.

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

The prospectus supplement with respect to each series of securities will state the terms of the offering of the securities, including:

the name or names of any underwriters or agents;

the purchase price of the securities and the proceeds to be received by us from the sale;

any underwriting discounts or agency fees and other items constituting underwriters' or agents' compensation;

any initial public offering price;

any discounts or concessions allowed or reallowed or paid to dealers; and

any securities exchange on which the securities may be listed.

If we use underwriters in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

negotiated transactions;

at a fixed public offering price or prices, which may be changed;

at market prices prevailing at the time of sale;

at prices related to prevailing market prices; or

at negotiated prices.

If dealers are utilized in the sale of offered securities, we will sell such offered securities to the dealers as principals. The dealers may then resell such offered securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction.

Offered securities may be sold directly by us to one or more institutional purchasers, or through agents designated by us from time to time, at a fixed price or prices, which may be changed, or at varying prices determined at the time of sale. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

As one of the means of direct issuance of offered securities, we may utilize the service of an entity through which it may conduct an electronic "dutch auction" or similar offering of the offered securities among potential purchasers who are eligible to participate in the auction or offering of such offered securities, if so described in the applicable prospectus supplement.

If so indicated in the applicable prospectus supplement, we will authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase offered securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject only to those conditions set forth in the prospectus supplement and the prospectus supplement will set forth the commission payable for solicitation of such contracts.

The securities may also be offered and sold, if so indicated in the prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. The prospectus supplement will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

Underwriters, dealers, agents and remarketing firms may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters, dealers, agents and remarketing firms may be required to make. Underwriters, dealers, agents and remarketing agents may be customers of, engage in transactions with, or perform services in the ordinary course of business for us and/or our affiliates.

Each series of securities will be a new issue of securities and will have no established trading market. The securities will not be listed on a national securities exchange. Any underwriters to whom securities are sold by us for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

LEGAL MATTERS

Unless otherwise indicated in the applicable prospectus supplement, Thomas C. Jepperson, Esq., Vice President and General Counsel for Questar Corporation, and Latham & Watkins LLP, Houston, Texas will act as counsel to us.

Item 15. Indemnification of Officers and Directors.

Reference is made to Section 16-10a-901 through 16-10a-909 of the Utah Revised Business Corporation Act, which provides for indemnification of directors and officers in certain circumstances.

Our Bylaws provide that we may voluntarily indemnify any individual made a party to a proceeding because he is or was our director, officer, employee or agent against liability incurred in the proceeding, but only if we have authorized the payment in accordance with the applicable statutory provisions of the Utah Revised Business Corporation Act (Sections 16-10a-902, 16-10a-904, 16-10a-906 and 16-10a-907) and a determination has been made in accordance with the procedures set forth in such provision that such individual conducted himself in good faith, that he reasonably believed his conduct, in his official capacity with us, was in our best interests and that his conduct, in all other cases, was at least not opposed to our best interests, and that he had no reasonable cause to believe his conduct was unlawful in the case of any criminal proceeding. The foregoing indemnification in connection with a proceeding by or in the right of us is limited to reasonable expenses incurred in connection with the proceeding, which expenses may be advanced by us. Our Bylaws provide that we may not voluntarily indemnify our director, officer, employee or agent in connection with a proceeding by or in the right of us in which such individual was adjudged liable to us or in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him.

Our Bylaws provide further that we shall indemnify our director, officer, employee or agent who was wholly successful, on the merits or otherwise, in defense of any proceeding to which he was a party because he is or was such a director, officer, employee or agent, against reasonable expenses incurred by him in connection with the proceeding.

Our Bylaws further provide that no director of ours shall be personally liable to us or our shareholders for monetary damages for any action taken or any failure to take any action, as a director, except liability for (a) the amount of a financial benefit received by a director to which he is not entitled; (b) an intentional infliction of harm on us or the shareholders; (c) for any action that would result in liability of the director under the applicable statutory provision concerning unlawful distributions; or (d) an intentional violation of criminal law.

Questar Corporation, our parent, maintains an insurance policy on behalf of our officers and directors pursuant to which (subject to the limits and limitations of such policy) the officers and directors are insured against certain expenses in connection with the defense of actions or proceedings, and certain liabilities which might be imposed as a result of such actions or proceedings, to which any of them is made a party by reason of being or having been a director or officer.

Item 16. Exhibits.

See the Exhibit Index attached to this registration statement and incorporated herein by reference.

Item 17. Undertakings.

(a)

The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for purposes of determining liability under the Securities Act of 1933 to any purchaser:

(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed t o be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in

II-2

the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(d)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act ("Act") in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Salt Lake, State of Utah, on the 31st day of March, 2010.

Re:

Questar Market Resources, Inc.

Registration Statement on Form S-3

Ladies and Gentlemen:

I am acting as counsel to Questar Market Resources, Inc., a Utah corporation (the "Company"), in connection with the Registration Statement on Form S-3 (the "Registration Statement"), filed on March 31, 2010 by the Company with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act"). The Registration Statement relates to the issuance and sale from time to time by the Company, pursuant to Rule 415 of the General Rules and Regulations promulgated under the Act, of the debt securities of the Company, in one or more series (the "Debt Securities"), to be issued under the Indenture, dated as of March 1, 2001 (the "Indenture"), between the Company and Wells Fargo Bank, N.A., as successor trustee to Bank One N.A. (the "Trustee").

This opinion is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

In connection with this opinion, I have examined originals or copies, certified or otherwise identified to my satisfaction, of:

the Registration Statement relating to the Debt Securities;

the Articles of Incorporation of the Company, as amended and currently in effect (the "Articles of Incorporation");

the Bylaws of the Company, as amended and currently in effect (the "Bylaws");

an executed copy of the Indenture;

the Form T-1 of the Trustee filed as an exhibit to the Registration Statement; and

resolutions adopted by the Board of Directors of the Company (the "Board of Directors") or committees thereof relating to the registration of the Debt Securities and related matters.

I, or attorneys under my supervision, have also examined originals or copies, certified or otherwise identified to my satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as I have deemed necessary or appropriate as a basis for the opinions set forth below.

In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as facsimile, electronic, conformed, certified or photostatic copies, and the authenticity of the originals of such copies. In making my examination of executed documents, or documents to be executed, I have assumed that the parties thereto, other than the Company,

had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents, and the validity and binding effect thereof on such parties. I have also assumed that any Debt Securities that may be issued will be issued in a form that complies with the Indenture and will be manually signed or countersigned, as the case may be, by duly authorized officers of the Trustee. As to any facts material to the opinions expressed herein that I did not independently establish or verify, I have relied upon oral or written statements and representations of officers and other representatives of the Company and others and of public officials.

My opinion set forth herein is limited to the Utah Revised Business Corporation Act ("Opined on Law"). I do not express any opinion with respect to the laws of any other jurisdiction other than the Opined on Law or as to the effect of any such laws on the opinion set forth herein. I am admitted to the Bar of the State of Utah, and to the extent that the opinion set forth herein relates to matters under the laws of the State of New York, I have relied on the opinion of Latham & Watkins LLP, special counsel to the Company, which is being filed as Exhibit 5.2 to the Registration Statement.

Based upon and subject to the foregoing and to the limitations, qualifications, exceptions and assumptions set forth herein, I am of the opinion that:

With respect to any series of Debt Securities offered by the Company (the "Offered Debt Securities"), when (i) the Registration Statement, as finally amended (including all necessary post-effective amendments), has become effective under the Act; (ii) an appropriate prospectus supplement or term sheet with respect to the Offered Debt Securities has been prepared, delivered and filed in compliance with the Act and the applicable rules and regulations thereunder; (iii) if the Offered Debt Securities are to be sold pursuant to a firm commitment underwritten offering, the underwriting agreement with respect to the Offered Debt Securities has been duly authorized, executed and delivered by the Company and the other parties thereto; (iv) the Board of Directors, including any appropriate committee appointed thereby, and appropriate officers of the Company have taken all necessary corporate action to approve the issuance , sale and terms of the Offered Debt Securities and related matters; (v) the Indenture and a supplemental indenture, officers' certificate or board resolution in respect of such Debt Securities has been duly executed and delivered by each party thereto; (vi) the terms of the Offered Debt Securities and of their issuance and sale have been duly established in conformity with the Indenture and any supplemental indenture, officers' certificate or board resolution to be entered into or adopted in connection with the issuance of such Debt Securities so as not to violate any applicable law, the Articles of Incorporation or the Bylaws or result in a default under or breach of any agreement or instrument binding upon the Company and so as to comply with any requirement or restriction imposed by any court or governmental body having jurisdiction over the Company; and (vii) the Offered Debt Securities have been issued in a form that complies with the Indenture and have been duly executed and authenticated in accordanc e with the provisions of the Indenture and any supplemental indenture, officers' certificate or board resolution to be entered into or adopted in connection with the issuance of such Debt Securities and duly delivered to the purchasers thereof upon payment of the agreed-upon consideration therefor, the Offered Debt Securities, when issued and sold in accordance with the Indenture, any supplemental indenture or officers' certificate to be entered into in connection with the issuance of such Debt Securities and the applicable underwriting agreement, if any, or any other duly authorized, executed and delivered valid and binding purchase or agency agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except to the extent that enforcement thereof may be limited by (a) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to creditors' rights generally, (b) general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity), (c) public policy considerations which may limit the rights of parties to obtain remedies, (d) the waivers of any usury defense contained in the Indenture, any supplemental indenture or the Offered Debt Securities that may be unenforceable, (e) requirements that a claim with

respect to any Offered Debt Securities denominated in a currency, currency unit or composite currency other than United States dollars (or a judgment denominated other than in United States dollars in respect of such claim) be converted into United States dollars at a rate of exchange prevailing on a date determined pursuant to applicable law, and (f) governmental authority to limit, delay or prohibit the making of payments outside the United States or in foreign currencies, currency units or composite currencies.

Opinion of Latham & Watkins LLP

Questar Market Resources, Inc.

180 East 100 South

P.O. Box 45601
Salt Lake City, UT 84145-0601

Re:

Questar Market Resources, Inc.

Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as special counsel to Questar Market Resources, Inc., a Utah corporation (the "Company"), in connection with the registration and sale by the Company from time to time of the debt securities (the "Debt Securities") under an Indenture dated as of March 1, 2001 (the "Indenture"), between the Company and Wells Fargo Bank, N.A., as successor trustee to Bank One N.A. (the "Trustee") pursuant to a registration statement on Form S-3 under the Securities Act of 1933, as amended (the "Act"), filed with the Securities and Exchange Commission (the "Commission") on March 31, 2010 (the "Registration Statement"). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectu s, other than as expressly stated herein with respect to the enforceability of the Debt Securities.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon the foregoing and upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters.

We are opining herein as to the internal laws of the State of New York, and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction, or as to any matters of municipal law or the laws of any local agencies within any state. Various issues pertaining to Utah law and the due authorization of the Debt Securities by the Company are addressed in the opinion of Thomas C. Jeppersen, Esq., separately provided to you. We express no opinion as to those matters.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof:

When the specific terms of the Debt Securities have been duly authorized and duly established in accordance with the Indenture and authorized by all necessary corporation action of the Company, and the Debt Securities have been duly executed, authenticated and issued in accordance with the Indenture and delivered against payment therefor in the manner contemplated by the Registration Statement and/or the applicable prospectus and by such corporate action, the Debt Securities will be a legally valid and binding obligation of the Company, enforceable against the Company in accordance with their respective terms.

The Indenture is the legally valid and binding agreement of the Company, enforceable against the Company in accordance with its terms.

The opinion rendered in the preceding paragraph relating to the enforceability of the Debt Securities is subject to: (i) the effect of bankruptcy, insolvency, reorganization, preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and (iv) we express no opinion as to (a) any pro vision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, arbitration, remedies or judicial relief, (c) the waiver of rights or defenses; (d) any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy; (e) any provision permitting, upon acceleration of the Debt Securities, collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon; (f) the creation, validity, attachment, perfection, or priority of any lien or security interest, (g) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (h) waivers of broadly or vaguely stated rights, (i) provisions for exclusivity, election or cumulation of rights or remedies, (j) provisions authorizing or validating conclusive or discretionary determinations, (k) grants of setoff rights, (l) proxies, powers and trusts, (m) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property, (n) any provision to the extent it requires that a claim with respect to the Debt Securities (or a judgment in respect of such a claim) be converted into U.S. dollars at a rate of exchange at a particular date, to the extent applicable law otherwise provides; and (o) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed (a) that the Indenture has been duly authorized, executed and delivered by the parties thereto, (b) that the Indenture constitutes a legally valid and binding obligation of the Trustee, enforceable against it in accordance with its terms, and (c) that the status of the Indenture and the Debt Securities as legally valid and binding obligations of the respective parties thereto is not affected by any (i) breaches of, or defaults under, agreements or instruments, (ii) violations of statutes, rules, regulations or court or governmental orders, or (iii) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities.

This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Registration Statement and to the reference to our firm contained in the related prospectus under the heading "Legal Matters." In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

Very truly yours,
