PROXY STATEMENT

FOR 2008 ANNUAL MEETING OF STOCKHOLDERS

We are furnishing you this proxy statement in connection with the solicitation of proxies by our Board of Directors to be voted at the 2008 Annual Meeting of Stockholders of Warren Resources, Inc. The Annual Meeting will be held on Wednesday, May 21, 2008. In this proxy statement, Warren Resources, Inc. is referred to as the "Company" or "Warren." This proxy statement and the enclosed proxy card are first being mailed to stockholders on or about April 15, 2008.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Where and when is the Annual Meeting?

The Annual Meeting will be held at The Cornell Club, 6 East 44^th Street, New York, NY 10017, on Wednesday, May 21, 2008, at 9:30 a.m. local time.

What is the purpose of the Annual Meeting?

At the Annual Meeting, Stockholders will vote upon:

•: The election of three directors for three-year terms;
•: the ratification of the appointment of Grant Thornton LLP as our independent auditors for fiscal year 2008; and
•: any other matters that may properly come before the meeting.

How does the Board recommend that I vote?

The Board recommends that you vote:

•: FOReach of the nominees for director;
•: FORthe ratification of Grant Thornton, LLP as our independent auditor for 2008.

Why should I vote?

Your vote is very important to the Board, even if you cast a dissenting vote. Regardless of the number of shares you hold, the Board strongly encourages you to exercise your right to vote as a stockholder of the Company.

Who may vote?

All Stockholders of record of Warren's common stock at the close of business on April 10, 2008, which we refer to as the record date, are entitled to receive notice of the Annual Meeting and to vote the shares of common stock held by them on the record date. Each outstanding share of common stock entitles its holder to cast one vote for each matter to be voted upon.

What is a proxy?

It is your legal designation of another person to vote the stock you own. That other person is called a proxy. If you designate someone as your proxy in a written document, that document also is called a proxy or a proxy card. We have designated two of our directors as proxies for the 2008 Annual Meeting of Stockholders. These are directors: Michael R. Quinlan and Chet Borgida.

What is a proxy statement?

It is a document that Securities and Exchange Commission ("SEC") regulations require us to give you when we ask you to sign a proxy card designating Michael R. Quinlan and Chet Borgida as proxies to vote on your behalf.

What is the difference between a Stockholder of record and a Stockholder who holds stock in street name?

•: If your shares are registered in your name, you are a stockholder of record.
•: If your shares are held in the name of your broker, bank or depository, your shares are held in street name.

How do I vote?

If your shares of common stock are held by a broker, bank, or other nominee (i.e., in "street name"), you will receive instructions from your nominee, which you must follow in order to have your shares voted. The instructions may appear on the special proxy card provided to you by your nominee (also called a "voting instruction form"). Your nominee may offer you different methods of voting, such as by telephone or Internet.

If you hold your shares of common stock in your own name as a holder of record, you may vote in person at the Annual Meeting or instruct the proxy holders named in the enclosed proxy card how to vote your shares by marking, signing, dating, and returning the proxy card in the postage-paid envelope that we have provided to you.

Proxies that are executed, but do not contain any specific instructions, will be voted "FOR" the election of the nominees for directors specified in this proxy statement and "FOR" ratification of the appointment of auditors. The persons named in the proxy will have authority to vote in accordance with their own discretion on any other matters that properly come before the meeting.

Who may attend the meeting?

Only Stockholders on the record date are invited to attend the Annual Meeting. Proof of ownership of Warren Resources, Inc.'s common stock, as well as a form of personal identification photo, may be requested in order to be admitted to the Meeting. If you are a Stockholder of record, your name can be verified against our Stockholder list. If you hold your Warren shares in "street name"—for instance, through a broker—you must request a proxy from your broker or other nominee holding your shares in record name on your behalf in order to attend the meeting and vote at that time (your broker may refer to it as a "legal" proxy). If you own shares in street name, bring your most recent brokerage statement with you to the meeting. We can use that to verify your ownership of Common Stock and admit you to the meeting;however, you will not be able to vote your shares at the meeting without a legal proxy from your broker.

Stockholders will be admitted to the Annual Meeting beginning at 9:15 a.m. No cameras, recording equipment or electronic devices will be permitted in the Meeting and large bags, briefcases or packages may be subject to inspection.

What are the quorum and voting requirements to elect the nominees for director and to ratify the appointment of our independent auditors?

The presence, in person or by proxy, of holders of at least a majority of the total number of outstanding shares of common stock entitled to vote is necessary to constitute a quorum for the transaction of business at the Annual Meeting. As of the record date of April 10, 2008, there were 58,274,680 shares of common stock outstanding.

For proposal 1, the election of directors, the three nominees receiving the greatest number of votes at the Annual Meeting will be elected, even though such nominees may not receive a majority of the votes cast.

For proposal 2, ratification of the appointment of our independent auditors, the appointment of the auditors will be ratified if the votes cast "for" ratification exceed the votes cast "against."

For any other business that may properly come before the Annual Meeting, the vote of a majority of the shares voted on the matter will constitute the act of the Stockholders on that matter, unless the law, or our articles of incorporation or bylaws, require the vote of a greater number.

How are votes counted?

Each share of common stock is entitled to one vote on each matter submitted to the Stockholders. Abstentions and "broker non-votes" will be counted only for purposes of establishing a quorum, but will not otherwise affect the outcome of the voting. Broker non-votes are proxies received from brokers or other nominees holding shares on behalf of their clients who have not received specific voting instructions from their clients with respect to non-routine matters. In counting the votes cast, only those cast "for" and "against" a matter are included, although you cannot vote "against" a nominee for director.

If you hold your shares of common stock in your own name as a holder of record, and you fail to vote your shares, either in person or by proxy, the votes represented by your shares will not affect the vote. If, however, your shares are held in "street name" and you fail to give instructions as to how you want your shares voted, the broker, bank or other nominee may vote the shares in their own discretion on certain routine matters, including the election of directors.

Will other matters be voted on at the Annual Meeting?

We are not aware of any other matters to be presented at the Annual Meeting other than those described in this proxy statement. If any other matters not described in the proxy statement are properly presented at the meeting, proxies will be voted in accordance with the discretion of the proxy holders.

Can I revoke my proxy?

You may revoke your proxy at any time before it has been exercised by:

•: Filing a written revocation with the Corporate Secretary at the following address: Warren Resources, Inc., 1114 Avenue of the Americas, 34th Floor, New York, NY 10036;
•: Filing a duly executed proxy bearing a later date; or
•: Appearing in person and voting by ballot at the Annual Meeting.

Any Stockholder of record as of the record date attending the Annual Meeting may vote in person whether or not they previously have given a proxy, but the presence (without further action) of a Stockholder at the Annual Meeting will not constitute revocation of a previously given proxy.

What other information should I review before voting?

Our 2007 annual report to Stockholders, including financial statements for the fiscal year ended December 31, 2007, is being mailed to Stockholders concurrently with this proxy statement. The annual report, however, is not part of the proxy solicitation material. A copy of our annual report on Form 10-K filed with the Securities and Exchange Commission (the SEC), including the financial statements, may be obtained without charge by:

•: Accessing Warren's website atwww.warrenresources.com or the EDGAR database at the SEC's website atwww.sec.gov, or
•: Writing to Warren Resources, Inc., Investor Relations, Warren Resources, Inc., 1114 Avenue of the Americas, 34th Floor, New York, NY 10036;

You also may obtain copies of our Form 10-K from the SEC at prescribed rates by writing to the Public Reference Section of the SEC, 450 Fifth Street, N.W., Washington, D.C. 20549. Please call the SEC at (800) SEC-0330 for further information on the SEC's public reference rooms.

Your vote is very important. Please take the time to vote by completing and mailing the proxy card. A postage-prepaid envelope has been provided for your convenience. If your proxy card is returned unsigned, then your vote cannot be counted. If the returned proxy card is signed and dated without indicating how you want to vote, then your proxy will be voted as recommended by the Board of Directors.

Where can I find the voting results of the meeting?

We will announce voting results at the meeting, and we will publish the final results in our quarterly report on Form 10-Q for the second quarter of 2008. You can get a copy of this and other reports free of charge on the Company's website atwww.warrenresources.com, or by contacting our Investor Relations Department at (212) 697-9660.

WARREN RESOURCES BOARD OF DIRECTORS

Item 1—Election of Directors

The Company's By-Laws provide for the annual election of Directors. The Company's By-Laws also provide that the number of Directors shall be determined by the Board, which has set the number at eleven.

We have no reason to believe that any of the nominees will be unable or unwilling for good cause to serve if elected.

Lead Director at the Non-Employee Directors' Executive Sessions

The Board of Directors has elected Mr. Quinlan as its Lead Director. As Lead Director, Mr. Quinlan's role is to aid and assist the Chairman and the remainder of the Board of Directors in assuring effective corporate governance in managing the affairs of the Board of Directors and the Company.

Additionally, Mr. Quinlan presides at executive sessions of the non-employee directors.

Meetings of the Board of Directors

The chair of the Audit, Compensation or Corporate Governance Committee leads non-employee board and committee sessions and the independent director sessions and is chosen by the non-employee directors and independent directors, respectively, based on who is the most knowledgeable and appropriate leader given the subject of the meeting. The session leader can retain independent consultants and schedule meetings. The non-employee directors met four times in 2007.

Compensation of Directors

Non-employee directors receive a combination of cash and stock-based compensation designed to attract and retain qualified candidates to serve on the Board.

The following discussion and analysis of compensation ("CD&A") arrangements of our named executive officers ("NEOs") for 2007 should be read together with the compensation tables and related disclosures set forth below. This discussion contains forward looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from currently planned programs as summarized in this discussion.

Compensation Philosophy

Our overall compensation philosophy is to provide a compensation package that enables us to attract, retain and motivate senior executives to achieve our short-term and long-term business goals. Consistent with this philosophy, the following goals provide a framework for our NEO compensation program:

The primary objectives of our executive compensation programs are:

•: motivating NEOs to achieve and even exceed strategic, operational and financial short-term and long-term goals by rewarding strong execution with individual compensation;
•: attracting, engaging, developing and retaining high performing NEOs who must operate in a high demand environment;
•: aggregate the elements of total compensation to reflect competitive market requirements and to address strategic business needs;
•: expose a significant portion of each NEOs compensation to risk, the degree of which will positively correlate to the level of the NEOs responsibility and performance; and
•: aligning the interests of executives and stockholders.

To achieve these objectives, Warren uses a mix of compensation elements, including:

•: base salary;
•: cash incentives;
•: equity incentives;
•: employee benefits; and
•: change of control benefits.

Role and Processes of the Compensation Committee

Our executive compensation program is administered by the Compensation Committee of the Board of Directors. The members of this Committee are Anthony Coelho, Chairman, Chet Borgida, Dominick D'Alleva and Espy Price, each an independent, non-employee director. In 2007, the Compensation Committee met twice and all members of the Compensation Committee were present during those meetings.

Under the terms of its Charter, the Compensation Committee is responsible for recommending to the Board of Directors the type and level of compensation to be granted to our executive officers. In fulfilling its role, the Compensation Committee:

•: grants stock options and restricted stock units under the Stock Incentive Plans,
•: recommends to the Board the compensation levels, including annual salary, bonus and stock options, for executives and other employees, as necessary, and
•: reviews on a periodic basis the operation and administration of our executive compensation programs.

We offer our executives annual base salaries, annual cash incentive compensation, long-term incentive compensation and other employee benefits that are intended to be competitive with those offered at similar oil and gas exploration and production companies with comparable market capitalization, assets and sales. We review compensation paid at these companies because their size and business make them most comparable to us. We also believe these companies likely compete with us for executive talent. We engage a compensation consultant to identify annually the median compensation paid to executives holding equivalent positions or having similar responsibilities at these companies. These companies change from time to time. We may also use general compensation surveys sponsored by nationally recognized compensation consulting firms to assist us in making compensation decisions.

During 2007, the Compensation Committee and the Company relied on compensation information produced by a consulting firm retained by management in August 2006. The Committee and the Company engaged Mercer Consulting to provide us with median compensation information for peer companies. For 2007, we generally benchmarked the compensation that we pay to our executives against the median compensation that 14 peer group companies (the "E&P Peer Group") pay to their executives. We benchmark against median compensation because it allows us to attract and retain employees, provides an incentive for employees to strive for better than average performance to earn better than average compensation, and helps us to manage the overall cost of our compensation program. The compensation information provided by the consultant includes median base salary, annual cash incentive compensation, long-term incentive compensation and total direct compensation. Total direct compensation is the sum of base salary, annual cash incentive compensation and long-term incentive compensation. Our current E&P Peer Group companies include:

Energy Partners, Ltd.
Petroleum Development Corp.
Resource America, Inc.
Meridian Resource Corp.
Brigham Exploration Co.
Goodrich Petroleum Corp.
Berry Petroleum Company

Swift Energy Company
Venoco, Inc.
McMoran Exploration Co.
Carrizo Oil & Gas, Inc.
Clayton Williams Energy, Inc.
Parallel Petroleum Corporation
PetroQuest Energy, Inc.

The Compensation Committee received the compensation recommendations from our Chief Executive Officer ("CEO"), relevant background information on our executives and officers and compensation studies conducted by Mercer Consulting. The Compensation Committee then reviewed the compensation recommendation with the CEO for all executives, except for the CEO. The CEO was not present during the discussion of his compensation.

Commencing in 2007, the Compensation Committee delegated the authority to make initial option grants to new employees (within an approved range) to the CEO within a pre-approved compensation matrix. All new employee grants in excess of the CEO limit, subsequent grants to existing employees and any grant to executives are approved by the Compensation Committee.

Compensation Program

In order to achieve the objectives discussed above, the elements of our total compensation packages include base salary and annual bonus, all paid in cash, as well as long-term compensation in the form of stock options or restricted common stock, employee benefits and change of control benefits. We believe that appropriately balancing the total compensation package and ensuring the viability of each element of the package is necessary in order to provide market-competitive compensation. The costs of our compensation programs are a significant determinant of our competitiveness. Accordingly, we are focused on ensuring that the balance of the various components of our compensation program is optimized to motivate employees to improve our results on a cost-effective basis.

Review of External Data

Each year, we survey the compensation practices of our peers in the United States in order to assess our competitiveness. In August 2006, Mercer Consulting, Inc., a compensation consultant, prepared an analysis and report for the Compensation Committee, which analyzed data from oil and gas exploration and production companies in our size and market capitalization range (the "E&P Peer Group"). Mercer conducted assessments in three areas of compensation: (1) total direct compensation (base salary) for our NEOs; (2) target total cash compensation (salary and bonus); and (3) equity (stock option grants). Mercer Consulting analyzed compensation for most executive positions of the E&P Peer Group. We based the compensation levels for 2007 on the data from the E&P Peer Group.

For NEOs in fiscal year ended December 31, 2007, the Compensation Committee generally targeted the aggregate value of our total cash compensation (base salary and bonus) for our senior management at the 50^th to 75^th percentile of the E&P Peer Group. We strongly believe in engaging the best talent in critical functions, and this may entail negotiations with individual executives who may have significant retention packages in place with other employers. In order to attract such individuals to our Company, we may determine that it is in our best interests to negotiate packages that deviate from the general principle of targeting total compensation at the fiftieth percentile of our E&P Peer Group. Similarly, we may determine to provide compensation outside of the normal cycle to individuals to address retention issues.

Compensation Elements

Cash Compensation

Base Salary

Base salary is primarily determined by competitive pay and individual job performance. Base salaries for NEOs are reviewed annually or more frequently should there be significant changes in responsibilities. In each case, we take into account the results achieved by the NEO, his or her future

potential, scope of responsibilities and experience, and competitive salary practices. Approved increases in base salary were effective February 2007.

The Company's performance in fiscal 2007 was a reflection, to a certain extent, on our CEO's individual performance. After reviewing our CEO's 2006 performance in January 2007, the Compensation Committee decided to increase our CEO's base salary for 2007 by approximately 3.3%, reflecting the increase in the 2007 Consumer Price Index for New York. This placed his salary in the 50^th to 75^th percentile of the E&P Peer Group according to Mercer Consulting. We believe our increase of our CEO's salary for 2007 was justified given our Company's exceptional performance during his tenure. During fiscal year ended December 31, 2007, our revenue increased by approximately 71%, and our net income increased by approximately 83% from fiscal 2006.

The NEOs received base salary increases for 2007 as follows based on the individual NEO's performance and a review of the Company's E&P Peer Group:

•: Mr. Larkin's base salary was increased by 3.3%, which placed his salary in the 50^th to 75^th percentile of the E&P Peer Group.
•: Mr. Gobble's base salary was increased by 5.0%, which placed his salary in the 50^th to 75^th percentile of the E&P Peer Group.
•: Mr. Davies' base salary was increased by 2.4%, which placed his salary in the 50^th to 75^th percentile of the E&P Peer Group.

For 200, Mr. Berwager received no increase in base salary because he had only become employed by the Company in November 2006. The range of this distribution above reflects positioning and particular individual performance. Although the range in base pay adjustments is fairly broad, the final base salaries for the NEOs are within a reasonable range of the 60th percentile of the E&P Peer Group, which is the Committee's target for the NEOs considering the comparatively higher cost-of-living and state taxation in the city and state where Warren is headquartered.

Incentive Bonuses

Our annual cash incentive bonus plan is designed to reward and retain employees for achieving financial and operating goals that are key to the success of our business and aligned with the near and long term interests of our Company and our shareholders. Management sets incentive bonus targets for each eligible employee as a percentage of base salary based on their position. At the beginning of each fiscal year, the Compensation Committee, working with management, will set oil and gas production and operating income goals for our Company. Generally goals are set at or above prior year results and budgeted levels. Each NEO's bonus will be based upon their individual performance and contribution.

In February 2007, the Compensation Committee approved internal operational, financial and safety measures including a minimum level of performance above which bonuses begin to accrue, a target level of performance required to earn the target bonus payout and the respective weightings for each measure.

The calculations for the bonus payouts for 2007 considered the following corporate operating goals:

•: increases in oil and gas production volume growth;
•: increases in cash flow from operations; and
•: reductions in drilling costs, operating expenses and other factors.

During the fiscal year ended December 31, 2007, the bonus targets for our NEOs were as follows: 150% of base salary for the CEO; 100% of base salary for the CFO; 75% of base salary for other

Executive Vice Presidents ("EVPs") and between 30% and 75% of base salary for Senior Vice Presidents and Vice Presidents. Each year, the bonus and commissions structure is reviewed to ensure that the design and payment structure is consistent with our compensation philosophy and competitive with our designated E&P Peer Group.

In 2007, as further described below, Warren achieved the initial threshold performance amount in a majority of its corporate operating goals. As a result, the incentive bonus pool for all employees in 2007 which was paid in 2008 was $1.5 million. The five NEOs received $0.9 million of the total bonus pool, representing 63% of the total cash bonus pool. This compares to the 2006 bonus pool of $0.5 million which was paid in 2007. The cash bonus amount for each NEO shown in the Summary Compensation table below is a reflection of the success or lack thereof in achieving our corporate goals.

The incentive bonus for each NEO was calculated as follows:

Target Bonus($)		X		Performance Unit Multiplier(%)		X		Individual Results(%)		=		Bonus Payment
Base salary times applicable target incentive multiplier				Derived from aggregating the target bonus of all participants in the Executive Bonus Plan and achievement of identified corporate operating goals				Based on each executive officer's achievement of individual goals tied to the corporate operating plan and strategic objectives; could not exceed 150%

The allocation of each executive's individual results percentage was determined by the Compensation Committee with respect to the bonus awarded to our CEO; by the Compensation Committee and our CEO with respect to the bonus awarded to our EVPs; and by the Compensation Committee, our CEO and Chief Financial Officer ("CFO") for all other executive officers.

Please refer to the Non-Equity Incentive Compensation Plan Compensation column under the Summary Compensation Table below for actual cash bonus amounts earned in fiscal year ended 2007.

Total Cash Compensation

As reflected in the Summary Compensation Table below, the total cash compensation for Mr. Swanton, Mr. Larkin, Mr. Gobble and Mr. Berwager is between the 50^th and 75^th percentile of the E&P Peer Group and the total cash compensation for Mr. Davies is between the 25^th and 50^th percentile of the E&P Peer Group.

Long-term Compensation

Equity Incentives

The equity incentive component of our executive compensation program consists of grants of (i) annual stock options and restricted stock units, and (ii) new-hire stock options. We use equity compensation to motivate and reward strong performance and retain valued executives, as equity compensation typically vests over a period of three years after the date of grant. New-hire equity grants also act as a means to attract qualified candidates. Warren strongly believes that equity awards serve to align the interests of its executives with those of its stockholders. By having a substantial portion of the executive officer's target compensation at risk through equity compensation, executives are motivated to align themselves with our stockholders when taking actions that will benefit us in the long-term.

The Compensation Committee, with input from our CEO and CFO (other than with respect to their own compensation), determined the level of equity compensation opportunity based upon competitive data and each executive officer's relative position, responsibilities, performance over the previous fiscal year, and anticipated future performance and responsibilities.

Stock options

Based on our compensation philosophy, a substantial portion of our compensation program rewards the long-term performance of our Company, and the retention of NEOs. Long-term compensation is delivered to our NEOs through stock options granted upon their initial hire, and through ongoing annual grants. Similar to base salary increases, option grants are also granted to reflect promotions and significant changes in responsibility. Although the expense of stock options affects our financial statements negatively, we continue to believe that this is an important element of compensation that forces NEOs to focus on our long-term financial and operational performance, and forces NEOs to work toward the creation of stockholder value. Stock options were granted with an exercise price that was equal to the fair market value of our common stock on the grant date. As a result, the executives will only be able to realize value if our common stock price rises and our stockholders also realize value. In order to provide an incentive for continued employment, stock options granted under the Stock Incentive Plans are "time-based," and generally 1/3^rd vest one year after grant, 1/3^rd after two years after grant and 1/3^rd after three years after grant. Stock option grants generally expire five years from the date of the grant. This schedule provides a reasonable time frame to align each NEO's compensation with the appreciation of the Company's stock price, while managing potential dilution effectively.

Initial stock option grants and annual option grants for plan participants are generally determined within ranges established for each job level. These ranges are established based on our desire to position compensation levels relative to the competitive market. Specific recruitment needs are taken into account for establishing the levels of initial option grants. Annual option grants take into consideration a number of factors, including performance of the individual, job level, prior grants and competitive external levels. The goals of option grant guidelines are to ensure future grants remain competitive from a grant value perspective, and to ensure option usage consistent with option pool forecasts.

Option grant practice

The Compensation Committee has provided the CEO with the authority to make initial option grants to new employees (within an approved range). During 2007, initial hire grants that were within the CEO's approved range were granted on the employee's start date. Based on the definition of "fair market value" in our Stock Incentive Plan, options are granted at 100% of the closing sales price of our stock on the last market trading date prior to the grant date.

For annual option and restricted stock grants to all employees, the Compensation Committee reviews and approves recommendations from the CEO. These grants are usually granted in March after our annual report on Form 10-K is filed with the SEC. For 2007, these grants were made on March 9, 2007. As a matter of policy, annual grants are made on the second business day after the day of our previous year earnings release and our annual report on Form 10-K is filed with the SEC or the next trading day. This timing enables management and the Compensation Committee to consider performance by both the Company and the individual, and to balance such performance against our expectations for the current year. This timing also ensures that all current financial and operating information is made publicly available before any grants are made. We do not time the granting of our options or restricted stock units with any favorable or unfavorable news released by the Company. The initial grants are based on the date of hiring of our new employees.

Restricted Stock grant practice

Restricted stock provides NEOs an opportunity to receive shares of Company stock provided they remain employed with the Company for a set period of time. Awards of restricted stock provide a valuable retention element to the overall compensation package for our NEOs. As with stock options, restricted stock awards provide a stock ownership vehicle and direct link to shareholder value creation since the value of the award can fluctuate up or down with changes in the Company's stock price. Restricted stock awards typically vest equally over three years from the date of grant. NEOs receive any dividends on the shares and also have voting rights. Generally, an NEO will forfeit any unvested restricted shares if the NEO terminates voluntarily or is terminated for cause prior to the vesting date.

The following table shows a comparison of the annual stock option and restricted stock grants made to the five most highly compensated employees during fiscal years ended 2007 and 2006:

	2007		2006
NEO	Stock Option Awards	Restricted Stock Awards	Stock Option Awards		Restricted Stock Awards
Norman F. Swanton	150,000	—	100,000		—

Bruce A. Berwager	15,000	—	50,000	(1)	—

(1): Granted to Mr. Berwager upon joining Warren in November 2006.

Retirement and Deferred Compensation Benefits

We do not provide our executive officers with a defined benefit pension plan or any supplemental executive retirement plans, nor do we provide our executive officers with retiree health benefits. Warren's employees, including the NEOs, may participate in Warren's 401(k) Retirement Savings Plan, which provides for a matching contribution by Warren of up to 100% of the employee's matching contribution, which is limited to $15,500 in fiscal year 2007 and $15,500 in fiscal year 2008. Warren makes a matching contribution to help attract and retain employees and to provide an additional incentive for our employees to save for their retirement in a tax-favored manner.

For a discussion of valuation assumptions, seeNote A—Stock-Based Compensation of the Notes to Consolidated Financial Statements included in our annual report under Item 8 of the Form 10-K for the year ended December 31, 2007.

At their discretion, the Compensation Committee has the authority to pay any NEO in excess of or below their targeted bonus amount. The goals for 2007 were approved by the Compensation Committee in February 2007. The payout amounts for each NEO were reviewed and approved by the Compensation Committee and the Board of Directors in February 2008 upon completion of the consolidated financial statements for fiscal 2007.

As mentioned in the CD&A, we grant stock options to new employees. Following the initial hire, additional grants are made to participants pursuant to a periodic annual grant program or following a significant change in job responsibilities, scope or title. For 2007, all grants to NEOs are the annual grants. According to the Stock Incentive Plans, fair market value that is used to determine the exercise price for option grants is defined as the NASDAQ closing price of the Company's stock on the market trading of the grant date. Options granted to NEOs during fiscal 2007 expire 5 years from the date of grant and vest 1/3^rd after one year, 1/3^rd after two years and 1/3^rd after three years.

We adopted SFAS 123(R) on January 1, 2007, see Note A under Item 8 of the 2007 Annual Report on Form 10-K. The grant date fair value of the option awards is calculated using the Black-Scholes valuation model using the following assumptions:

Assumptions	Rate
Average risk free interest rate	4.5	%
Average expected term (years)	3.5
Average expected volatility	44	%

NEO Employment Arrangements

We have entered into employment agreements with each of the NEOs. In addition to the specific provisions of each employment agreement as described below, each of these employment agreements provides that if the executive's employment is terminated without cause, due to death or disability or for "good reason", including a change of control, all unvested stock options granted to the executive shall become immediately vested.

Norman F. Swanton. We entered into an employment agreement effective January 1, 2001, as amended and effective January 1, 2007, with Norman F. Swanton, our president, chief executive officer and chairman. This agreement provides for a base salary of $555,316 per year, subject to annual cost of living adjustments, participation in our standard insurance plans for our executives, and participation in our other incentive compensation programs at the discretion of the Board of Directors. Under his agreement, if Mr. Swanton's employment is terminated without cause and he executes a full and general release in favor of, and satisfactory to the Company, Mr. Swanton will be entitled to termination compensation equal to the greater of two years' annual base salary, or all of the base salary for the remainder of his employment term. Additionally, if terminated without cause or there is a "change in control" of Warren (as defined in the agreement), all unvested stock options and restricted common stock become immediately vested. Mr. Swanton's employment agreement automatically renews for an additional year on each anniversary of the effective date of the amended agreement, unless we notify Mr. Swanton or he notifies us in writing 90 days prior to such anniversary that we, or he, is not renewing his employment agreement. No such notice of non-renewal has been presented by either party. Accordingly, Mr. Swanton's employment agreement has been renewed through December 31, 2008. As a result of the annual cost of living adjustment over the prior year, his base salary for 2008 is $576,936.

Timothy A. Larkin. We entered into an employment agreement effective January 1, 2001, as amended and effective January 1, 2007, with Timothy A. Larkin, our executive vice president and chief financial officer. This agreement provides for a base salary of $305,424 per year, subject to annual cost of living adjustments, participation in our standard insurance plans for our executives, and participation in our other incentive compensation programs at the discretion of the Board of Directors. Under his agreement, if Mr. Larkin's employment is terminated without cause and he executes a full and general release in favor of, and satisfactory to, the Company, Mr. Larkin will be entitled to termination compensation equal to the greater of two years' annual base salary, or all of the base salary for the remainder of the employment term. Additionally, if terminated without cause or there is a "change in control", all unvested stock options and restricted common stock become immediately vested. Mr. Larkin's employment agreement automatically renews for an additional year on each anniversary of the effective date of the amended agreement, unless we notify Mr. Larkin or he notifies us in writing 90 days prior to such anniversary that we, or he, will not be renewing his employment agreement. No such notice of non-renewal has been presented by either party. Accordingly, Mr. Larkin's employment agreement has been renewed through December 31, 2008. As a result of the annual cost of living adjustment over the prior year, his base salary for 2008 is $317,315.

Lloyd G. Davies. We entered into an employment agreement effective March 1, 2007 with Lloyd G. Davies, our executive vice president and the chairman and chief executive officer of Warren E&P, Inc. This agreement provides for a base salary of $268,990 per year, participation in our standard insurance plans for our executives, and participation in our other incentive compensation programs at the discretion of the Board of Directors. Under his agreement, if Mr. Davies' employment is terminated without cause and he executes a full and general release in favor of, and satisfactory to, the Company, Mr. Davies will be entitled to termination compensation equal to the greater of three month's base salary or all of the base salary for the remainder of the employment term. Additionally, if terminated without cause or there is a "change in control", all unvested stock options and restricted common stock become immediately vested. Mr. Davies' employment agreement expires on December 31, 2007, but will automatically renew on each anniversary of the effective date for an additional year unless we notify Mr. Davies or he notifies us in writing 90 days prior to such anniversary that we, or he, will not be renewing his employment agreement. No such notice of non-renewal has been presented by either party. Accordingly, such employment agreement has been renewed through December 31, 2008. As a result of the annual cost of living adjustment over the prior year, his base salary for 2008 is $279,462.

Change of Control Benefits—Severance Arrangements

The table below reflects potential payments to our NEOs under existing contracts, agreements, plans or arrangements, whether written or unwritten, for various scenarios involving a change of control or termination of employment of each NEO, assuming a December 31, 2007 termination date, and, where applicable, using the closing price of our common stock of $14.13 (as reported on the NASDAQ Stock Market as of December 31, 2007).

The following are general definitions that apply to the termination scenarios detailed below. These definitions have been summarized and are qualified in their entirety by the full text of the applicable plans or agreements to which our executive officers are parties.

"Involuntary Termination" is generally defined as any terminationthat does not result from the following termination events:

•: resignation;
•: retirement;
•: for cause;
•: death;
•: qualifying disability;
•: extended leave of absence; or
•: continued failure to perform duties or responsibilities.

"For Cause" is generally defined as:

•: the willful and continued failure of the executive to perform substantially the executive's duties with the Company or one of its affiliates (other than any such failure resulting from incapacity due to physical or mental illness) or material breach of any material provision in an employment agreement (if applicable), after written demand for substantial performance is delivered to the executive by the Board or the CEO of the Company which specifically identifies the manner in which the Board or CEO believes that the executive has not substantially performed the executive's duties, or
•: the willful engaging by the executive in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company.

A "Change of Control" is generally defined as any one of the following occurrences:

•: any individual, entity or group acquires beneficial ownership of 50% or more of either the outstanding shares of our common stock or our combined voting power;
•: individuals who constitute the Board (as of the date of either a given change of control contract or an award agreement under our equity plans, as applicable) cease to constitute a majority of the Board, provided that an individual whose election or nomination as a director is approved by a vote of at least a majority of the directors as of the date of either the change of control contract or an award agreement under our equity plans, as applicable, will be deemed a member of the incumbent Board;
•: the date of approval by the stockholders of the Company of an agreement providing for the merger or consolidation of the Company with another corporation or other entity where (x) stockholders of the Company immediately prior to such merger or consolidation would not beneficially own following such merger or consolidation shares entitling such stockholders to 50% or more of all votes (without consolidation of the rights of any class of stock to elect

directors by a separate class vote) to which all stockholders of the surviving corporation would be entitled in the election of directors, or (y) where the members of the Board of Directors, immediately prior to such merger or consolidation, would not, immediately after such merger or consolidation, constitute a majority of the board of directors of the surviving corporation; or

•: the sale of all or substantially all of the assets of the Company.

"Good Reason" is generally defined as any one of the following occurrences:

•: Material diminution in Executive's position, authority, duties or responsibilities;
•: any Change of Control event;
•: any material change in the location, as defined in the applicable agreement, where the Executive was employed immediately preceding the relocation.

"Disability" is generally defined as the absence of the Executive from the Executive's duties with the Company on a full-time basis for 180 business days as a result of incapacity due to mental or physical illness which is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive's legal representative.

Under their Employment Agreements, if the Board of Directors terminates Mr. Swanton or Mr. Larkin other than "For Cause" or if Mr. Swanton or Mr. Larkin terminates his employment for "Good Reason", Mr. Swanton and Mr. Larkin are entitled to severance pay equal to two-years of their then-current base salary, and the most recent years' incentive bonus. All of the other NEOs, with the exception of Mr. Berwager who receives one year's severance, receive three months of their base salary as severance payments if terminated other than "For Cause" or the NEO terminates his employment for Good Reason.

Based on a hypothetical termination date of December 31, 2007, the cash severance payments for five NEOs would have been as follows:

Name	Salary-based		Bonus-based		Accelerated Equity Compensation(1)		Severance Total
Norman F. Swanton	$	1,110,632	$	181,675	$	561,666	$	1,853,973
Timothy A. Larkin	$	610,848	$	81,297	$	341,321	$	1,033,466
Lloyd G. Davies	$	67,248		—	$	150,400	$	217,648
Kenneth Gobble	$	61,687		—	$	150,400	$	212,087
Bruce Berwager	$	132,500		—	$	107,633	$	240,133

(1): Reflects the in-the-money value of unvested stock options and the value of unvested restricted stock units, all as of December 31, 2007 based upon the closing price of $14.13 per share as reported by the NASDAQ Stock Market.

Compensation Committee Interlocks and Insider Participation

During 2007, the Compensation Committee consisted of Anthony Coelho, Chairman, Chet Borgida, Dominick D'Alleva and Espy Price. None of these individuals served as one of the Company's officers or employees at any time during 2007 and none was formerly an officer of the Company with the exception of Mr. D'Alleva who was our Secretary until 2002. None of the Company's executive officers served during 2007 as a member of the compensation committee of any other company that has an executive officer serving as a member of the Compensation Committee or the Board of Directors. None of the Company's executive officers served during 2007 as a member of the board of directors of any other company that has an executive officer serving as a member of the Compensation Committee.

Compensation Committee Report

The Compensation Committee is responsible for establishing and administering the executive compensation programs of the Company. The Compensation Committee of the Company has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

Respectfully Submitted,

THE COMPENSATION COMMITTEE
/s/ Anthony Coelho, Chairman
/s/ Chet Borgida
/s/ Dominick D'Alleva
/s/ Espy Price

The above report of the Compensation Committee of the Company shall not be deemed to be "soliciting material" or to be "filed" with the Securities and Exchange Commission, nor shall this report be incorporated by reference into any filing made by the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

Director and Officer Indemnification Agreements

The Company has entered into indemnification agreements with its directors and certain executive officers, in part to enable the Company to attract and retain qualified directors and executive officers. These agreements require the Company, among other things, to indemnify such persons against certain liabilities that may arise by reason of their status or service as directors or officers, to advance their expenses for proceedings for which they may be indemnified and to cover such person under any directors' and officers' liability insurance policy the Company may maintain from time to time. These agreements are intended to provide indemnification rights to the fullest extent permitted under applicable Maryland law and are in addition to any other rights the Company's directors and executive officers may have under the Company's restated certificate of incorporation, bylaws and applicable law.

Equity Compensation Plan Information

The following table provides information as of December 31, 2007, with respect to shares of our common stock that may be issued under our existing equity compensation plans, all of which have been approved by our Stockholders.

2000 Equity Incentive Plan	1,975,000	1,219,259	$	10.80	121,241

In the event that Warren or Warren E&P is acquired by merger, consolidation, asset sale or equity sale, outstanding options will be assumed, or equivalent options will be issued by the successor corporation. If the successor corporation refuses to assume or substitute the options, the compensation

committee may accelerate the participants' rights to exercise for a limited period of time after which the options would terminate. With respect to restricted stock awards, the compensation committee could also elect to terminate any vested awards in exchange for cash payments.

Certain Relationships and Related Transactions

TRANSACTIONS WITH RELATED PERSONS, PROMOTERS AND CERTAIN CONTROL PERSONS

The Company's board of directors has adopted a Code of Ethics and Business Conduct, which prohibits conflicts of interest between a director, officer or employee and the Company. The code requires directors, officers and employees to inform the Company of any transaction that involves related parties and that may give rise to a conflict of interest. Our Audit Committee, pursuant to the Audit Committee Charter, has oversight for related person transaction and compliance with our code. The Audit Committee will review, ratify or approve, as necessary, any related person transactions prior to the transaction being entered into, or ratify any related person transactions that have not been previously approved, in which a director, five percent owner, executive officer or immediate family member of any such person has a material interest, and which the transaction is in an amount in excess of $120,000, either individually or in the aggregate of several transactions during any calendar year. As of the current date, no director, five percent owner, executive officer or immediate family member of any such person has such a material interest for an amount in excess of $120,000.

Item 2—Ratification of Appointment of Independent Auditors

The Audit Committee has appointed Grant Thornton LLP to serve as independent auditors for the fiscal year ending December 31, 2008, and are presenting the selection to the Stockholders for ratification. Grant Thornton LLP has served as the Company's independent auditors for many years and is considered by management to be well qualified.

Audit Committee

For many years, the Company has had an Audit Committee composed entirely of non-management directors. The members of the Audit Committee meet the independence and experience requirements of the Nasdaq Stock Market and the New York Stock Exchange. In 2007, the Committee met seven times. The Committee has adopted, and annually reviews, a charter outlining the practices it follows; a copy of the charter is available at our website atwww.warrenresources.com. The charter complies with all current regulatory requirements.

The following report of the Audit Committee of the Company shall not be deemed to be "soliciting material" or to be "filed" with the Securities and Exchange Commission, nor shall this report be incorporated by reference into any filing made by the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

Audit Committee Report

The Audit Committee is responsible for monitoring the integrity of the Company's consolidated financial statements, the Company's system of internal controls, the Company's risk management, the qualifications and independence of the Company's independent auditor, the performance of the Company's internal and independent auditors and the Company's compliance with legal and regulatory requirements. We have the sole authority and responsibility to select, determine the compensation of, evaluate and, when appropriate, replace the Company's independent auditors. The Committee has four independent directors and operates under a written charter adopted by the Board. The Board has determined that each Committee member is independent under the standards of director independence established under our Corporate Governance Policies and the Nasdaq Stock Market listing

requirements and is also "independent" for purposes of Section 10A(m)(3) of the Securities Exchange Act of 1934.

Management is responsible for the financial reporting process, including the system of internal controls, for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America and for the report on the Company's internal control over financial reporting. The Company's independent auditors are responsible for auditing those financial statements and expressing an opinion as to their conformity with accounting principles generally accepted in the United States of America and for attesting to management's report on the Company's internal control over financial reporting. Our responsibility is to oversee and review the financial reporting process and to review and discuss management's report on the Company's internal control over financial reporting. We are not, however, professionally engaged in the practice of accounting or auditing and do not provide any expert or other special assurance as to such financial statements concerning compliance with laws, regulations or generally accepted accounting principles or as to auditor independence. We rely, without independent verification, on the information provided to us and on the representations made by management and the independent auditors.

We held seven meetings during 2007. The meetings were designed, among other things, to facilitate and encourage communication among the Committee, management and the Company's independent auditors, Grant Thornton LLP. We discussed with Grant Thornton LLP the overall scope and plans for our audits. We met with Grant Thornton LLP, with and without management present, to discuss the results of their examination and their evaluation of the Company's internal controls. During 2007, the Company changed its method of accounting for its oil and gas exploration and development activities from the successful efforts method to the full cost method. The Audit Committee met with management and the independent auditor to review and discuss this change in accounting principle

We reviewed and discussed the Company's compliance with Section 404 of the Sarbanes-Oxley Act of 2002, including the Public Company Accounting Oversight Board's (PCAOB) Auditing Standard No. 2 regarding the audit of internal control over financial reporting.

We reviewed and discussed the Company's guidelines, policies and procedures for financial risk assessment and risk management and the major risk exposures of the Company and its business units, as appropriate. We reviewed and discussed with management its reports on risk management.

We reviewed and discussed the audited consolidated financial statements for the year ended December 31, 2007 with management and Grant Thornton LLP. We also reviewed and discussed the unaudited Quarterly Reports on Form 10-Q with management and Grant Thornton LLP. We also discussed with management and Grant Thornton LLP the process used to support certifications by the Company's Chief Executive Officer and Chief Financial Officer that are required by the Securities and Exchange Commission and the Sarbanes-Oxley Act of 2002 to accompany the Company's periodic filings with the Securities and Exchange Commission and the processes used to support management's annual report on the Company's internal controls over financial reporting.

We also discussed with Grant Thornton LLP matters that independent accounting firms must discuss with audit committees under generally accepted auditing standards and standards of the PCAOB, including, among other things, matters related to the conduct of the audit of the Company's consolidated financial statements and the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (Communication with Audit Committees).

Grant Thornton LLP also provided to the Committee the written disclosures and the letter required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and represented that it is independent from the Company. We discussed with Grant Thornton their independence from the Company. When considering Grant Thornton LLP's independence, we considered if services they provided to the Company beyond those rendered in

connection with their audit of the Company's consolidated financial statements, reviews of the Company's interim condensed consolidated financial statements included in its Quarterly Reports on Form 10-Q were compatible with maintaining their independence. We also reviewed, among other things, the audit, audit-related and tax services performed by, and the amount of fees paid for such services to, Grant Thornton LLP. We received regular updates on the amount of fees and scope of audit, audit-related and tax services provided.

Based on our review and these meetings, discussions and reports, and subject to the limitations on our role and responsibilities referred to above and in the Audit Committee Charter, we recommended to the Board that the Company's audited consolidated financial statements for the year ended December 31, 2007 be included in the Company's Annual Report on Form 10-K. We have also selected Grant Thornton LLP as the Company's independent auditors for the year ending December 31, 2008 and are presenting the selection to the Stockholders for ratification.

Dated: April 15, 2008

Audit Fees and Services

The following table sets forth the aggregate fees billed to the Company in each of the last two fiscal years by Grant Thornton LLP:

	2007		2006
Audit Fees	$	370,650	$	380,818
Audit Related Fees		46,342		35,880
Tax Fees(1)		27,200		29,500
All Other Fees		–0–		–0–

Totals	$	444,192	$	446,198

(1): Represents fees for assisting management in the preparation of the corporate tax return.

Consistent with SEC policies regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent auditor. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent auditor.

Prior to engagement of the independent auditor, management submits an aggregate of services expected to be rendered during that year for each of four categories of services to the Audit Committee for approval.

1.: Audit services include audit work performed in the annual audit of the financial statements, as well as work that generally only the independent auditor can reasonably be expected to provide, including quarterly reviews, consents and assistance with and review of documents filed with the SEC, comfort letters, statutory audits, and attest services and consultation regarding financial accounting and/or reporting standards.
2.: Audit-Related services are for assurance and related services that are traditionally performed by the independent auditor, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.

3.: Tax services include all services performed by the independent auditor's tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance.
4.: Other Fees are those associated with services not captured in the other categories. The Company generally doesn't request such services from the independent auditor.

Prior to engagement, the Audit Committee pre-approves these services by category of service. The fees are budgeted and the Audit Committee requires the independent auditor and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent auditor for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires specific pre-approval before engaging the independent auditor.

The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

For 2007 and 2006, 100% of the accounting fees and services were pre-approved by the Audit Committee.

Ratification of the appointment of the independent auditors requires that the votes cast by the holders of the shares of Common Stock voting in person or by proxy at the Annual Meeting of Stockholders "for" ratification exceed the votes cast "against." If the Stockholders should not ratify the appointment of Grant Thornton LLP, the Audit Committee will reconsider the appointment.
