Dear URI Stockholder:

You are cordially invited to attend a special meeting of stockholders of Uranium Resources, Inc. ("URI"), to be held on January 29, 2014 at 9:00 a.m., local time, at our headquarters, located at 6950 South Potomac Street, Suite 300, Centennial, Colorado 80112. We are calling the special meeting to ask you to consider and vote on a proposal to approve the recent senior secured loan agreement entered into between URI and Resource Capital Fund V L.P. ("RCF") and the issuance of shares of URI common stock upon the conversion of the amounts drawn under the loan agreement or otherwise issuable thereunder.

As previously announced, we entered into the loan agreement with RCF, our largest stockholder, on November 13, 2013, and we borrowed an initial $3.0 million under the loan agreement shortly thereafter. Subject to the satisfaction of certain conditions, another $2.0 million will be available to us following stockholder approval of the loan agreement at the special meeting, and two additional tranches of $5.0 million each will be available between April 15, 2014 and June 30, 2014 and between July 15, 2014 and September 30, 2014, respectively, at our election. The loan agreement is intended to support our operating costs through 2014.

Drawdown of the facility was possible prior to stockholder approval of the loan agreement because the initial $3.0 million drawn is not convertible into shares of URI common stock until stockholder approval at the special meeting. Following stockholder approval, RCF may convert amounts drawn under the loan agreement into shares of URI common stock at a rate of $2.60 per share, subject to adjustment. If we fail to obtain stockholder approval by January 31, 2014, we will be unable to draw the remaining $12.0 million available under the loan agreement and will be required to repay the initial $3.0 million advance by April 1, 2014. We had a cash balance of approximately $1.9 million as of December 11, 2013.

RCF beneficially owns approximately 32.8% of our outstanding common stock and is, in the normal course, able to vote at stockholder meetings. However, our Board of Directors has determined, and RCF concurs, that as a matter of good corporate governance shares owned by RCF and its affiliates should not determine the outcome of the meeting, and approval of the loan agreement and the issuance of shares thereunder will be subject to the approval of a majority of votes cast at the special meeting, excluding shares beneficially owned by RCF or its affiliates. As a consequence, disinterested stockholders will determine the outcome of the vote.

Our Board of Directors unanimously recommends a vote "FOR" the approval of the loan agreement and the issuance of shares of URI common stock thereunder.

Please read the accompanying proxy statement for information about the matters to be voted upon. Your vote is important. Whether or not you plan to attend the meeting in person, we urge you to submit your proxy as soon as possible via the internet, by telephone or by mailing the enclosed proxy card.

Very truly yours,

PROXY STATEMENT FOR SPECIAL MEETING OF STOCKHOLDERS TO BE HELD JANUARY 29, 2014

This proxy statement and the enclosed proxy is furnished to stockholders of Uranium Resources, Inc., a Delaware corporation (the "Company" or "URI"), in connection with the solicitation of proxies by the Board of Directors of the Company (the "Board") for use at the Special Meeting of Stockholders (the "Special Meeting") to be held at the Company's offices located at 6950 South Potomac Street, Suite 300, Centennial, Colorado 80112 on January 29, 2014, at 9:00 a.m., local time, and any postponement or adjournments thereof, for the purposes set forth in the accompanying Notice of Special Meeting of Stockholders. This proxy statement and the enclosed proxy will first be mailed to stockholders of record on or about December 24, 2013.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE SPECIAL MEETING TO BE HELD ON JANUARY 29, 2014: This proxy statement and the proxy card are available at http://urre.client.shareholder.com .

Purpose of the Special Meeting

The Special Meeting is being called to consider the following matters:

Record Date and Outstanding Shares

The record date for the Special Meeting is December 11, 2013 (the "Record Date"). Only stockholders of record at the close of business on the Record Date are entitled to notice of, to attend and to vote at the Special Meeting. At the close of business on the Record Date, there were 19,800,690 shares of URI common stock outstanding and entitled to vote at the Special Meeting.

Voting

Each holder of URI common stock is entitled to one vote for each share of common stock held as of the close of business on the Record Date.

If you are a holder of record of URI common stock, you can vote in any one of the following ways:

ZEQ.=1,SEQ=4,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=477061,FOLIO='blank',FILE='DISK106:[13ZDG1.13ZDG18501]DA18501A.;17',USER='CHE105438',CD='21-DEC-2013;11:53'

Proxies submitted by telephone or the internet are treated in the same manner as if the stockholder had signed, dated and returned the proxy card by mail. Therefore, stockholders of record electing to vote by telephone or the internet should not return their proxy cards by mail.

If you hold your shares in "street name" through a broker, bank or nominee (an "Intermediary"), you can vote in any of the following ways:

Each of the proposals is a non-discretionary item, which means that if you do not provide voting instructions to the Intermediary that holds your shares, the Intermediary will not be able to vote your shares. In order to vote your shares, you must provide voting instructions to the Intermediary by the deadline provided in the materials you receive from the Intermediary. If the Intermediary that holds your shares cannot vote your shares on a particular matter because it has not received instructions from you, this is referred to as a "broker non-vote."

Voting of Proxies

Shares of URI common stock represented by properly executed proxies received before the Special Meeting will be voted at the Special Meeting in the manner specified on the proxies. Physical proxies that are properly executed and timely submitted but which do not contain specific voting instructions will be voted " FOR " each of the proposals presented at the Special Meeting.

Your vote is important. Accordingly, if you are a holder of URI common stock, please submit your proxy by telephone, through the internet or by mail, whether or not you plan to attend the Special Meeting in person. Proxies submitted by internet or telephone must be received by 11:59 p.m. eastern time on January 28, 2014. Proxies submitted by mail must be received by January 28, 2014. If your shares of common stock are held by an Intermediary, please provide a proxy from such Intermediary or direct the Intermediary how to vote your shares.

If you are a stockholder of record and you do not cast your vote, no votes will be cast on your behalf on any of the items of business at the Special Meeting.

Revocation of Proxies

You may revoke your proxy and/or change your vote at any time before your shares are voted at the Special Meeting.

If you are a holder of record of URI common stock, you can revoke your proxy and/or change your vote by:

ZEQ.=2,SEQ=5,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=750056,FOLIO='2',FILE='DISK106:[13ZDG1.13ZDG18501]DA18501A.;17',USER='CHE105438',CD='21-DEC-2013;11:53'

For shares you hold beneficially in "street name" through an Intermediary, you may change your vote by submitting new voting instructions to your Intermediary or, if you have obtained a legal proxy from your Intermediary giving you the right to vote your shares, by attending the Special Meeting and voting in person. In either case, the powers of the proxy holders will be suspended if you attend the Special Meeting in person and so request, although attendance at the Special Meeting will not by itself revoke a previously granted proxy.

Voting in Person

Stockholders of the Company may vote in person at the Special Meeting even if they already have provided their proxy in the manner described in this proxy statement and in the accompanying proxy card. Such stockholders must notify a representative of the Company at the Special Meeting of their desire to revoke their proxy and vote in person. Please note that shares of URI common stock may only be voted by the record owner of such shares, so stockholders whose shares are held in the name of an Intermediary and who wish to vote those shares in person at the Special Meeting must obtain a valid proxy from the Intermediary in order to vote the shares in person at the Special Meeting.

Votes Required

Assuming the presence of a quorum, the following vote is required for each proposal:

Recommendation of the Board Regarding the Proposals

The Board has approved each of the proposals and unanimously recommends that stockholders vote "FOR" Proposal 1 (proposal to approve the Loan Agreement and the issuance of shares of URI common stock thereunder) and "FOR" Proposal 2 (proposal to approve an adjournment of the Special Meeting, if necessary, if a quorum is present, to solicit additional proxies) . Your proxy will be so voted, unless you specify otherwise.

Vote Tabulation

The Company will appoint one or more inspectors of election to conduct the voting at the Special Meeting. Prior to the Special Meeting, the inspectors will sign an oath to perform their duties in an impartial manner and to the best of their abilities. The inspectors will ascertain the number of shares outstanding and the voting power of each share, determine the shares represented at the Special Meeting and the validity of proxies and ballots, count all votes and ballots and perform certain other

ZEQ.=3,SEQ=6,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=841956,FOLIO='3',FILE='DISK106:[13ZDG1.13ZDG18501]DA18501A.;17',USER='CHE105438',CD='21-DEC-2013;11:53'

duties as required by law. The inspectors will tabulate the number of votes cast for, against or abstaining. If you are a stockholder of record, your signed proxy card is returned directly to our transfer agent for tabulation. If you hold your shares in "street name" through an Intermediary, your Intermediary will return one proxy card to our transfer agent (or vote its shares as otherwise permitted) on behalf of its clients.

Quorum; Abstentions and Broker Non-Votes

In order to carry on the business of the Special Meeting, we must have a quorum. The presence, in person or by proxy, of the holders of one-third of the shares of URI common stock outstanding and entitled to vote on the Record Date is necessary to establish a quorum. Abstentions and broker non-votes will be considered as present at the Special Meeting for purposes of establishing a quorum.

Costs of Solicitation

The accompanying proxy is being solicited on behalf of the Board. All expenses for soliciting proxies for the Special Meeting, including the expense of preparing, printing and mailing the form of proxy and the material used in the solicitation thereof, will be borne by the Company. In addition to the use of the mails, proxies may be solicited by personal interview, telephone, electronic mail and facsimile by directors, officers and regular employees of the Company. None of the Company's directors, officers or employees will receive any additional compensation for soliciting proxies on behalf of the Board. We may also make arrangements with brokerage firms and other custodians, nominees and fiduciaries for the forwarding of soliciting material to the beneficial owners of URI common stock held of record by those owners. We will reimburse those brokers, custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses incurred in connection with that service. We have engaged Regan & Associates, Inc. to assist us with the solicitation of proxies for the Special Meeting. We expect to pay Regan & Associates, Inc. approximately $35,000 for their services.

No Dissenters or Appraisal Rights

Under the General Corporation Law of the State of Delaware, our Restated Certificate of Incorporation (as amended) and our Amended and Restated Bylaws, the holders of URI common stock will not be entitled to dissenter's rights or appraisal rights in connection with the proposals.

Description of Common Stock

Each share of URI common stock is entitled to one vote for all purposes and cumulative voting is not permitted in the election of directors. Accordingly, the holders of more than fifty percent of all of the outstanding shares of URI common stock can elect all of the Company's directors. There are no preemptive, subscription, conversion or redemption rights pertaining to the Company's common stock. Holders of URI common stock are entitled to receive such dividends as may be declared by the Company's Board of Directors out of assets legally available and to share ratably in the Company's assets upon liquidation.

Interest of Certain Persons in Matters to be Acted Upon

So long as any amounts remain outstanding under the Loan Agreement, RCF is entitled to have two designees placed in nomination for seats on the Company's Board of Directors. In addition, under a Stockholders' Agreement between RCF and the Company dated March 1, 2012, as subsequently modified by a Bridge Loan Agreement between the Company and RCF dated December 17, 2012, so long as RCF and its affiliates own or hold shares of URI common stock which in the aggregate exceed 10% of the Company's issued and outstanding common stock, RCF is entitled to have one designee placed in nomination for a seat on the Company's Board of Directors, and so long as RCF and its

ZEQ.=4,SEQ=7,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=57889,FOLIO='4',FILE='DISK106:[13ZDG1.13ZDG18501]DA18501A.;17',USER='CHE105438',CD='21-DEC-2013;11:53'

affiliates own or hold shares of URI common stock which in the aggregate exceed 25% of the Company's issued and outstanding common stock, RCF is entitled to have an additional designee placed in nomination for a seat on the Company's Board of Directors. John H. Pfahl and Mark K. Wheatley currently serve as RCF's designees to the Company's Board of Directors. Mr. Pfahl is employed as a Senior Associate by RCF Management L.L.C., an affiliate of RCF. Mr. Wheatley and RCF are also party to an agreement pursuant to which Mr. Wheatley may be entitled to additional compensation from RCF upon RCF's sale of its holdings in the Company. See Proposal 1, "Approval of Loan Agreement and Issuance of URI Common Stock ThereunderDescription of RCF Ownership and Control Rights" for additional information about RCF's ownership in the Company and certain control rights of RCF.

Other than the foregoing, no person who has served as a director or executive officer of the Company since the beginning of the last fiscal year, nor any associate of such person, has any substantial interest, direct or indirect, by security holdings or otherwise, in the proposals that is not shared pro rata by all other stockholders.

Other Business

The Board is not aware of any matter, other than the matters described in this proxy statement, to be presented for action at the Special Meeting. However, if any other business properly comes before the Special Meeting, the person or persons named in the enclosed form of proxy will vote the proxy in accordance with his, her or their best judgment on such matters.

PROPOSAL 1 APPROVAL OF LOAN AGREEMENT AND ISSUANCE OF URI COMMON STOCK THEREUNDER

General

On November 13, 2013, the Company, together with each of the Company's subsidiaries as guarantors, entered into the Loan Agreement with RCF, pursuant to which RCF provided a senior secured loan facility (the "Facility") to the Company under which the Company may draw up to $15.0 million. Under NASDAQ rules, the Company must seek stockholder approval before issuing any shares under the Loan Agreement. The Loan Agreement requires that the Company use its best efforts to call and hold a stockholders meeting by no later than January 31, 2014 in order to approve the issuance of shares thereunder. Accordingly, the Company is seeking stockholder approval of the Loan Agreement, a copy of which is attached hereto as Annex A , and the issuance of shares thereunder at the Special Meeting.

Reasons for Stockholder Approval

Our common stock is listed on the NASDAQ Capital Market and, as such, we are subject to the NASDAQ Marketplace Rules. NASDAQ Marketplace Rule 5635(d) requires that an issuer obtain stockholder approval prior to the issuance of common stock if such issuance is for less than the greater of book or market value of the common stock and would equal 20% or more of the common stock or voting power of the issuer outstanding before the issuance. The initial conversion price of amounts drawn under the Facility is $2.60 per share, which is less than the greater of the book or market value of our common stock immediately before we entered into the Loan Agreement. If the entire amount of the Facility is converted into common stock at a price of $2.60 per share, and interest and fees under the Loan Agreement are satisfied by the issuance of common stock, more than 20% of the Company's common stock outstanding before we entered into the Loan Agreement would be issued. In addition, the Loan Agreement includes anti-dilution adjustments that could result in a reduction of the conversion price in the future.

In addition, under the terms of the Loan Agreement, the Company agreed to use its best efforts to call and hold a stockholders meeting by no later than January 31, 2014 in order to approve the issuance of shares under the Loan Agreement. The Company is seeking stockholder approval of Proposal 1 in order to satisfy the requirements under the Loan Agreement.

Approval of Proposal 1 will constitute approval pursuant to NASDAQ Marketplace Rule 5635(d) and under the terms of the Loan Agreement.

Required Vote

This proposal to approve the Loan Agreement and the issuance of shares thereunder will be approved if a majority of the shares of URI common stock present or represented by proxy and entitled to vote at the Special Meeting, excluding shares beneficially owned by RCF or its affiliates, are voted in favor of such approval.

Although not required by Delaware law, NASDAQ rules or our charter or bylaws, our Board of Directors has determined, following a recommendation by its Finance Committee, that approval of Proposal 1 will require a majority of votes cast on the proposal, excluding shares beneficially owned by RCF or its affiliates. The Finance Committee believes, and the Board of Directors concurs, that approval of the Loan Agreement and the issuance of the shares thereunder by disinterested stockholders is a good corporate governance practice.

ZEQ.=1,SEQ=9,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=304453,FOLIO='6',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

Description of Loan Agreement and Facility

The Facility consists of three tranches of $5.0 million each. RCF advanced $3.0 million of the first tranche to the Company shortly following the closing of the Loan Agreement. Subject to the satisfaction of certain conditions, the remaining $2.0 million of the first tranche will be available to the Company following stockholder approval of the Facility at the Special Meeting, and two additional tranches of $5.0 million each will be available between April 15, 2014 and June 30, 2014 and between July 15, 2014 and September 30, 2014, respectively, at the election of the Company.

An establishment fee of $300,000 will be due by the fifth business day following the date of the Special Meeting, which amount will be satisfied by the delivery of shares if the Company's stockholders approve Proposal 1 and cash otherwise. Amounts drawn under the Facility carry an annualized interest rate of 12% until stockholder approval of the Facility and 10% thereafter. Upon an Event of Default, amounts drawn under the Facility incur an annualized interest rate of 17% until stockholder approval and 15% thereafter. Unused portions of the Facility incur a commitment fee of 1% through September 30, 2014 or earlier if the Company draws the third tranche in full before such date.

Amounts drawn under the Facility mature on December 31, 2016, or April 1, 2014 if stockholder approval of the Facility is not received on or before January 31, 2014. The Company may prepay all or any portion of the amounts drawn under the Facility without penalty, subject to a minimum prepayment amount of $5.0 million or (if lower) the full amount then outstanding. Prepaid amounts may not be redrawn.

Guarantees and Security

The Company's obligations under the Loan Agreement are guaranteed by each of the Company's direct and indirect subsidiaries. The Company's obligations under the Loan Agreement and the guarantees are secured by a lien on substantially all of the assets and property of the Company and the guarantors and by pledges of all of the equity interests of the Company's direct and indirect subsidiaries. Additionally, the Company's obligations under the Loan Agreement and the guarantees are secured by mortgages and a deed of trust on certain real and personal properties of the Company located in New Mexico and Texas.

Conversion of Facility; Issuance of Shares in Satisfaction of Interest and Fees

Following stockholder approval of the Loan Agreement and the issuance of shares thereunder, RCF may convert amounts drawn under the Facility (including amounts previously repaid) into shares of URI common stock at an initial rate of $2.60 per share, which would result in the issuance of 5,769,231 shares if the entire $15.0 million available under the Facility were converted. The conversion rate is subject to customary anti-dilution adjustments and further downward adjustment, subject to a floor of $1.00 per share, in the case of certain equity issuances by the Company before November 13, 2014.

In addition, following stockholder approval of the Loan Agreement and the issuance of shares thereunder, the Company intends, unless RCF elects otherwise, to issue 117,188 shares in satisfaction of the $300,000 establishment fee, valuing such shares at the volume weighted average price of the Company's common stock for the twenty trading days preceding October 18, 2013, as provided in the Loan Agreement.

Interest under the Facility and the 1% commitment fee may also be satisfied by the issuance of shares at RCF's election, in each case valued at the volume weighted average price of the Company's common stock for the twenty trading days preceding the most recent quarter end date before the issuance of such shares. If interest were to accrue on the full amount available under the Facility through December 31, 2016, and the Company's shares issued in satisfaction thereof were valued at

ZEQ.=2,SEQ=10,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=1014750,FOLIO='7',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

$2.60 per share, the Company estimates that it would issue approximately 1,593,248 shares in satisfaction of interest under the Facility. Similar, if the full commitment fee were incurred, and the shares issued were valued at $2.60 per share, the Company estimates that it would issue approximately 22,073 shares in satisfaction of the commitment fee. Both of these amounts could increase significantly if the value of the Company's common stock decreases.

If the Company were to issue all of the foregoing 7,501,740 shares upon conversion of the Facility and in satisfaction of interest and fees under the Loan Agreement, RCF's beneficial ownership in the Company would increase from approximately 32.8% to approximately 51.3%.

All shares issuable under the Loan Agreement are subject to registration under the Registration Rights Agreement, dated March 1, 2012, between the Company and RCF, under which the Company is required to register the shares on a shelf registration statement.

Representations, Warranties and Covenants

The Loan Agreement contains customary representations, warranties and covenants, including, without limitation, the following significant covenants:

Events of Default

The following constitute Events of Default under the Loan Agreement:

ZEQ.=3,SEQ=11,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=118138,FOLIO='8',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

Certain Control and Participation Rights

So long as any obligations remain outstanding under the Loan Agreement, RCF will have the right to nominate two individuals to serve on the Company's Board of Directors. Currently, John H. Pfahl and Mark K. Wheatley serve as RCF's designees to the Company's Board of Directors. RCF also has the right to participate in offerings by the Company of equity or equity-linked securities in proportion to RCF's partially diluted ownership in the Company.

Use of Proceeds

The Company intends to use the proceeds of the Facility for critical general and administrative costs, essential restoration commitments and limited technical studies.

The foregoing description of the Loan Agreement is qualified in its entirety by reference to the Loan Agreement, a copy of which is attached hereto as Annex A and incorporated by reference herein.

Description of RCF Ownership and Control Rights

As of December 11, 2013, RCF beneficially owned approximately 32.8% of the Company's common stock. If the Company were to draw the entire $15.0 million available under the Facility, RCF could elect to convert such amount into 5,769,231 shares of URI common stock at $2.60 per share, which would increase RCF's ownership in the Company from approximately 32.8% to approximately 48.0%. In addition, if RCF elects for interest and fees under the Loan Agreement to be satisfied by the issuance of shares, RCF's beneficial ownership could increase to 51.3% or more, which would give RCF control of the Company. RCF may also be able to exercise significant control over the Company with ownership of less than 50% of the Company's stock. See "Description of Loan Agreement and FacilityConversion of Facility; Issuance of Shares in Satisfaction of Interest and Fees" above for additional information about the number of shares issuable pursuant to the Loan Agreement.

Under a Stockholders' Agreement between RCF and the Company dated March 1, 2012, as subsequently modified by a Bridge Loan Agreement between the Company and RCF dated December 17, 2012, so long as RCF and its affiliates own or hold shares of URI common stock which in the aggregate exceed 10% of the Company's issued and outstanding common stock, RCF is entitled to have one designee placed in nomination for a seat on the Company's Board of Directors, and so long as RCF and its affiliates own or hold shares of URI common stock which in the aggregate exceed 25% of the Company's issued and outstanding common stock, RCF is entitled to have an additional

designee placed in nomination for a seat on the Company's Board of Directors. John H. Pfahl and Mark K. Wheatley currently serve as RCF's designees to the Company's Board of Directors. Mr. Pfahl is employed as a Senior Associate by RCF Management L.L.C., an affiliate of RCF. Mr. Wheatley and RCF are also party to an agreement pursuant to which Mr. Wheatley may be entitled to additional compensation from RCF upon RCF's sale of its holdings in the Company. RCF also has the right under the Stockholders' Agreement to participate in future equity and equity-linked offerings by the Company in proportion to its percentage ownership of the outstanding shares of the Company's common stock. As noted above, the Loan Agreement also provides RCF with the right to nominate two individuals to serve on the Company's Board of Directors and participate in future equity and equity-linked offerings.

Background of and Reasons for Entry into the Loan Agreement

The Company ceased producing uranium in 2009 as a result of low uranium prices. As a consequence, the Company is relying on financing activities to fund its operations until it resumes uranium production. Following a stockholder rights offering in the first quarter of 2013 that raised a net of $3.6 million and the return of $5.4 million to the Company upon securing new financial surety arrangements in the second quarter of 2013, the Company had sufficient cash to fund operations through October 2013.

In the fourth quarter of 2011, the Company entered into an At-The-Market Sales Agreement with BTIG, LLC, allowing the Company to sell from time to time common shares having an aggregate offering price of up to $15.0 million, through an "at-the-market" equity offering program ("ATM Sales Agreement"), $9.0 million of which remains unused. In July 2013, the Company began the process of completing necessary preliminary activities that would allow for the initiation of sales under the ATM Sales Agreement. However, on July 8, 2013, before sales under the ATM Sale Agreement could commence, the Staff of the Securities and Exchange Commission ("SEC") issued a comment letter in connection with the Staff's regular review of the Company's filings under the Securities Exchange Act of 1934, as amended. In light of the matters raised in the comment letter, the Company decided to avoid selling stock until the Staff's comments had been resolved.

The Company submitted a response to the July 8 comment letter on August 16, 2013, and the Staff issued another comment letter on August 29, 2013. Facing the prospect of resolving the Staff's comments in late 2013 or early 2014, by which time the Company would have exhausted its cash, URI management began exploring financing alternatives to the ATM Sales Agreement.

The Company and RCF had previously entered into a bridge loan agreement in December 2012 which provided interim financing to the Company until completion of the stockholder rights offering in March 2013. During the week of September 9, 2013, URI management contacted RCF about the possibility of again providing bridge financing to the Company. RCF indicated that it was not interested in providing bridge financing but that it would be interested in a convertible loan facility to fund the Company through March 2015. On September 13, 2013, RCF submitted a draft term sheet for a $15.0 million convertible secured loan facility to the Company.

After discussions with RCF and revisions to the draft term sheet, the Board of Directors met on September 19, 2013 to consider the proposed convertible loan facility from RCF. The Board formed a Finance Committee consisting solely of directors unaffiliated with RCF, and to that end appointed Terence J. Cryan, Paul K. Willmott, Marvin K. Kaiser and Christopher M. Jones to the Committee, with Mr. Cryan serving as Chairman of the Committee. The Board empowered the Finance Committee to, among other things: (i) review and evaluate the terms and conditions of financing transactions available to the Company and determine, together with its advisors (including independent counsel and financial advisors), whether the proposed financing transactions are fair to and in the best interests of the Company and its stockholders; (ii) consider a financing transaction with RCF and alternatives to a

ZEQ.=5,SEQ=13,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=457910,FOLIO='10',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

transaction with RCF; (iii) determine whether or not to proceed with a financing transaction; (iv) determine what actions, if any, should be taken by the Company with respect to financing, and approve the taking of such actions; (v) as appropriate or advisable for the purpose of achieving the best transaction reasonably attainable for the Company, negotiate the price, structure, form, terms and conditions of potential financings and the form, terms and conditions of any definitive agreements in connection therewith; and (vi) approve the issuance of the Company's securities in connection with any financings. The Board also determined not to recommend a financing transaction for approval by the Company's stockholders or otherwise approve a financing transaction without the Finance Committee's prior approval of such financing transaction.

The Finance Committee first met on September 19, 2013, reviewed in detail the RCF proposal and requested additional legal and financial advice be solicited by URI management to evaluate further the RCF proposal and to consider possible alternative offers.

The Finance Committee met on September 23, 2013 and representatives of Cowen and Company, the Company's financial adviser, joined the meeting along with representatives of Hogan Lovells US LLP ("Hogan Lovells"), the Company's outside counsel. Cowen made a presentation on the types of private deals that would generally be available to the Company and noted that any potential investors would have to execute a nondisclosure or confidentiality agreement. The Committee directed Cowen and Company to contact potential investors and procure term sheets from such investors. Legal counsel also reviewed with the Committee its fiduciary duties when considering the RCF proposal.

The Finance Committee next met on September 26, 2013. Representatives from Cowen and Company and representatives from Hogan Lovells were again present. URI management and Cowen discussed a term sheet previously circulated to the Committee from a potential investor ("Investor A"), which proposed a private placement of $10 million of convertible notes and warrants to purchase up to 65% of the principal amount of the convertible notes over a five-year term. The Finance Committee then discussed the RCF and Investor A term sheets in detail and identified proposed revisions to each. Legal counsel reviewed a privileged memorandum previously circulated to the Committee further addressing the Committee's fiduciary duties. The Committee decided to engage Richards, Layton & Finger, P.A. ("Richards Layton"), as independent counsel to the Committee.

The Company and Investor A executed a nondisclosure agreement on September 27, 2013.

On October 2, 2013, the Finance Committee met to discuss a revised term sheet from Investor A, which incorporated many changes requested by the Finance Committee but still included warrants which would enable the holders thereof to purchase up to 50% of the principal amount of the convertible notes over a four-year term, in addition to their ability to convert $10 million of notes. The Finance Committee also considered a term sheet from another potential investor ("Investor B") proposing a $1.5 million initial private placement of the Company's common stock, followed by a commitment to purchase additional shares upon demand for a total investment of up to $16 million but only following resolution of the Staff's comments. The Finance Committee considered $1.5 million insufficient to fund the Company's financial needs. URI management also identified a third potential investor ("Investor C") that was offering $8 million in private financing but no term sheet had yet been provided. The Finance Committee requested that Cowen and Company seek final and best terms from Investor A and Investor B and directed management to secure a term sheet from Investor C and to continue to seek additional term sheets for any other investors expressing interest. The Finance Committee also discussed the RCF term sheet and identified certain revisions, including (i) an increase in the advance available to the Company upon closing the Loan Agreement from $1.0 million to $3.0 million, (ii) a provision allowing the Company the right to decide whether to draw additional amounts under the Facility before such amounts may be converted, rather than permitting RCF to advance amounts for the purpose of immediate conversion, (iii) a floor on the conversion price on

ZEQ.=6,SEQ=14,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=1041026,FOLIO='11',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

amounts drawn under the Facility, and (iv) the right to raise additional capital below the conversion price during the 12 months following closing.

The Company and Investor B executed a mutual nondisclosure agreement on October 2, 2013.

On October 3, 2013, the Finance Committee met to review the status of discussions and negotiations with Investor A and Investor B. On October 4, 2013, the Finance Committee met to review a new term sheet from Investor C as well as a new term sheet from a fourth potential investor ("Investor D"). Both new term sheets contemplated public offerings and had terms similar to the term sheets from Investor A and Investor B, but neither provided specifics regarding the proposed transactions, as had been the case with the term sheets from Investor A and Investor B. Cowen and Company also communicated that the term sheets from Investor A and Investor B previously reviewed by the Finance Committee represented the best terms available to the Company from such investors. After extensive discussions, and after further advice from Cowen and Company and counsel, the Finance Committee resolved to enter advanced discussions with Investor A, provided that Investor A agreed to additional specific changes.

On October 6, 2013, Messrs. Cryan and Jones each separately discussed with a representative of RCF the nature of the proposal offered by Investor A and both learned for the first time that RCF was amenable to making several specific changes to its term sheet that had been previously requested by the Finance Committee. On October 7, 2013, the Finance Committee met to discuss the anticipated changes to the RCF term sheet and concluded that the URI management team should work with outside counsel to advance the RCF proposal. Later that day, Mr. Cryan discussed the status of the financing alternatives and the fiduciary obligations of the Committee with Richards Layton. On October 8, 2013, RCF sent a revised term sheet to the Company incorporating the changes requested by Messrs. Cryan and Jones and previously sought by the Finance Committee.

On October 9, 2013, the Finance Committee held a meeting to consider the two financing alternatives identified by the Committee as the best available to the Company: the revised RCF proposal and the proposal from Investor A. Mr. Jones reported that the RCF proposal had been revised as requested by the Finance Committee and the revised proposal had been reviewed and found acceptable by the URI management team. Mr. Cryan reported that based on his discussions with a representative of Richards Layton, the revised RCF proposal addressed the Committee's concerns involving a related party transaction with RCF because any decisions to draw upon the Facility beyond the initial $5 million first tranche was subject to further Board review and approval. The Finance Committee also discussed some final changes offered by Investor A to its proposal. The Finance Committee spent considerable time discussing each proposal, and then determined that the RCF transaction was in the best interests of the Company and its stockholders. In particular, the Finance Committee found that the RCF transaction presented the lowest risk of dilution to the Company's stockholders, provided adequate immediate funds to the Company, and allowed the greatest freedom to the Company to pursue alternative financial sources (including sales through the ATM Sales Agreement or other public offerings) following resolution of the SEC comments. Following the Finance Committee meeting and at its direction, Mr. Jones executed the RCF letter agreement on October 9, 2013, and delivered the letter agreement to RCF.

On October 28, 2013, Davis Graham & Stubbs LLP ("Davis Graham"), counsel to RCF, sent a draft of the Loan Agreement to the Company.

On October 28, 2013, the Company filed a Quarterly Report on Form 10-Q announcing the entry into the RCF letter agreement and summarizing the terms thereof. The Company issued a press release on October 29, 2013 and held a conference call on October 31, 2013 in which the RCF letter agreement was addressed.

ZEQ.=7,SEQ=15,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=512364,FOLIO='12',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

Between November 1 and November 6, 2013, counsel for the Company and RCF negotiated the terms of the Loan Agreement and certain ancillary documents. On November 7, 2013, following a discussion between URI management and RCF, Davis Graham sent a revised draft of the Loan Agreement incorporating the changes sought by URI management.

On November 8, 2013, following a review of the Loan Agreement and draft ancillary loan documents, the Finance Committee determined that the Loan Agreement and transactions contemplated thereby are fair to the Company and its stockholders (other than RCF) and approved the final version of the Loan Agreement and the transactions contemplated thereby.

The parties executed the Loan Agreement and related loan documents on November 13, 2013. The Company announced the entry into the Loan Agreement on November 19, 2013.

Certain Effects of Stockholder Approval

As of December 11, 2013, RCF beneficially owned approximately 32.8% of our common stock. If stockholders approve the Loan Agreement and the issuance of shares thereunder, and if URI management and the Board decide to draw upon the second and third tranches of the Facility, and if RCF elects to take shares in satisfaction of interest and fees due under the Loan Agreement, RCF's beneficial ownership of our common stock could increase to above 50%, giving RCF control of the Company, despite RCF having contractual rights to only two directors. RCF could also receive a significant number of additional shares if we were to sell equity or equity-linked securities in the year following the closing of the Loan Agreement at a price below RCF's conversion price. See "Description of RCF Ownership and Control Rights" above.

Because of RCF's current 32.8% beneficial ownership of URI common stock, RCF has the ability to exercise a substantial degree of control over matters requiring stockholder approval. Those matters include the election of directors, amendments to the certificate of incorporation and approval of significant corporate transactions. This control could have the effect of delaying or preventing a change of control of the Company or changes in management and will make the approval of certain transactions difficult without the support of RCF, including transactions in which other stockholders might otherwise receive a premium for their shares over the then-current market price. In addition, RCF could privately sell control of the Company without other stockholders realizing any change-of-control premium. RCF may also have other interests that are different from, in addition to or not always consistent with the Company's interests or with the interests of other stockholders. RCF's control over the Company could increase substantially following stockholder approval of the Loan Agreement and the issuance of the shares thereunder.

Certain Effects if Proposal 1 is Not Approved

If Proposal 1 is not approved, the Company will be required to repay the initial $3.0 million advance under the Facility on or before April 1, 2014. The Company will also be required to satisfy the $300,000 establishment fee, all interest incurred under the Facility and the 1% commitment fee with cash. In addition, the remaining $12.0 million under the Facility will not be available to the Company.

The Company had a cash balance of approximately $1.9 million as of December 11, 2013. The Company currently does not have adequate cash to satisfy the above obligations under the Loan Agreement if stockholders do not approve Proposal 1, and the Company will need to seek alternative sources of debt or equity capital to satisfy such obligations and fund its operations. To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, the issuance of such securities would likely result in substantial dilution to existing stockholders and could adversely affect our stock price. If the Company borrows money, assuming it can do so, it will have to pay interest and may also have to agree to restrictions that limit its operating flexibility.

ZEQ.=8,SEQ=16,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=493430,FOLIO='13',FILE='DISK106:[13ZDG1.13ZDG18501]DC18501A.;8',USER='MBRADT',CD='23-DEC-2013;14:05'

There can be no assurance that the Company will be able to obtain additional debt or equity capital if stockholders do not approve Proposal 1, that the terms of alternative capital would be as favorable to the Company as the Loan Agreement or that such additional capital could be obtained on a timely basis, if at all. If additional capital is not available in sufficient amounts or on a timely basis, the Company will experience liquidity problems in the near future, and the Company could face the need to significantly curtail current operations, change our planned business strategies and pursue other remedial measures. Any curtailment of business operations would have a material negative effect on operating results, the value of our outstanding stock is likely to fall, and our business may fail, causing our stockholders to lose their entire investment.

The Lender agrees promptly to notify the Borrower and the appropriate Credit Party after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application.

SCHEDULE 11.8 Dispute Resolution; Arbitration

Schedule. This schedule sets forth the dispute resolution provisions referred to in section 11.8 of the loan agreement (as amended, modified, supplemented, extended or restated, the "loan agreement") dated as of november 13, 2013 by and among uranium resources, inc., as the borrower, the subsidiaries of the borrower from time to time party thereto, as the guarantors, and resource capital fund v l.p., a cayman islands exempt limited partnership, as the lender. This schedule forms part of and is incorporated into the loan agreement. Capitalized terms used and not specifically defined in this schedule 11.8 shall have the meanings given thereto in the loan agreement. Any changes from time to time in the defined terms as specified in the loan agreement shall automatically be effective in this schedule 11.8 as and when made.
Dispute. For purposes of this Schedule and the Loan Agreement, the term "Dispute" shall mean any controversy, claim, dispute or disagreement between or among two or more Parties to the Agreement (but excluding any dispute with respect to which all of the Parties thereto are Credit Parties) arising out of, relating to, or otherwise in connection with the Loan Agreement, any other Loan Document or any other ancillary agreement related thereto, whether in tort, contract or otherwise, including any claim, dispute, disagreement or controversy relating to the meaning, interpretation, breach, default, termination, or invalidity of any provision hereof that is not otherwise settled by agreement between the Parties.
Notification. A Party that desires to submit a Dispute for resolution shall commence the dispute resolution process by providing written notice of the Dispute ("Notice of Dispute") to the other Parties to the Dispute. The Notice of Dispute shall identify the Parties to the Dispute, contain a brief statement of the nature of the Dispute and the relief requested, and shall request negotiations among Senior Executives of each Party to the Dispute. The submission of a Notice of Dispute shall toll any applicable statute of limitation related to the Dispute, pending the conclusion or abandonment of the dispute resolution process under this Article. Each Notice of Dispute and any other notice pertaining to a Dispute shall be delivered in accordance with Section 11.2 of the Loan Agreement.
Senior Executive Negotiations. The Parties to the Dispute shall first seek to resolve any Dispute by negotiation between Senior Executives. A "Senior Executive" means any individual who is an officer of a Party and has authority to negotiate a full and final settlement of the Dispute for a Party. Within twenty (20) days after the date of the receipt by each Party to the Dispute of the Notice of Dispute, the Senior Executives representing the Parties to the Dispute shall meet at a mutually acceptable time and place to exchange and discuss relevant information in an attempt to resolve the Dispute. If a Senior Executive intends to be accompanied at the meeting by an attorney, each other Party's Senior Executive shall be given written notice of such intention at least five (5) Business Days in advance and may also be accompanied by an attorney. The Senior Executives shall have a maximum of ten (10) days from the date of the initial meeting to discuss and resolve the Dispute, unless the Parties all agree in writing to extend such period of time. Unless the period for Senior Executive negotiations is extended by agreement of all of the Parties thereto, any Party may initiate arbitration proceedings concerning such Dispute at any time following the passage of thirty (30) days after receipt of the Notice of Dispute.
Arbitration. Any Dispute not finally resolved by Senior Executive negotiations shall be exclusively and definitively resolved through final and binding arbitration, it being the intention of the Parties that this is a broad arbitration agreement designed to encompass all possible disputes. Each Party waives the right to trial by jury with respect to any Dispute and agrees to submit such Dispute to binding arbitration in accordance with this Schedule 11.8.
Rules. The arbitration shall be conducted in accordance with the International Dispute Resolution Procedures (as then in effect) of the International Centre for Dispute Resolution (the "Rules"), except to the extent the Rules conflict with the provisions of this Schedule 11.8, in which event the provisions of this Schedule 11.8 will control.

ZEQ.=2,SEQ=87,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=564713,FOLIO='blank',FILE='DISK106:[13ZDG1.13ZDG18501]LY18501A.;14',USER='MVANGB',CD='13-DEC-2013;16:08'

Number of Arbitrators. If the amount in Dispute is not subject to quantification or is equal to or in excess of One Million United States Dollars (US$1,000,000), the arbitration shall be conducted by three (3) arbitrators, unless all parties to the Dispute agree in writing to a sole arbitrator within thirty (30) days after the filing of the arbitration with the International Centre for Dispute Resolution. If the amount in Dispute is less than One Million United States Dollars (US$1,000,000), the arbitration shall be conducted by one arbitrator.
Method of Appointment of the Arbitrators. All arbitrators appointed pursuant to the dispute resolution procedure described in this Schedule 11.8 shall have at least the following qualifications: (1) a lawyer who has practiced in the area of commercial law for at least ten (10) years or a retired judge of the courts of the United States; (ii) a person with at least ten (10) years experience in complex commercial transactions; or (iii) a person with at least ten (10) years experience in the mining industry. If the arbitration is to be conducted by a sole arbitrator, then the arbitrator will be jointly selected by the Parties to the Dispute. If the Parties to the Dispute fail to agree on the arbitrator within thirty (30) days after the filing of the arbitration, then the International Centre for Dispute Resolution shall appoint the arbitrator. If the arbitration is to be conducted by three (3) arbitrators and there are only two (2) Parties to the Dispute, then each party to the Dispute shall appoint one (1) arbitrator within thirty (30) days of the filing of the arbitration, and the two (2) arbitrators so appointed shall select the presiding arbitrator within thirty (30) days after the latter of the two arbitrators has been appointed by the Parties to the Dispute. If a Party to the Dispute fails to appoint its Party-appointed arbitrator or if the two (2) Party-appointed arbitrators cannot reach agreement on the presiding arbitrator within the applicable time period, then the International Centre for Dispute Resolution shall appoint the remainder of the three (3) arbitrators not yet appointed. If the arbitration is to be conducted by three (3) arbitrators and there are more than two (2) Parties to the Dispute, then within thirty (30) days of the filing of the arbitration, all claimants shall jointly appoint one (1) arbitrator and all respondents shall jointly appoint one (1) arbitrator, and the two (2) arbitrators so appointed shall select the presiding arbitrator within thirty (30) days after the latter of the two (2) arbitrators has been appointed by the Parties to the Dispute. If either all claimants or all respondents fail to make a joint appointment of an arbitrator or if the Party-appointed arbitrators cannot reach an agreement on the presiding arbitrator within the applicable time period, then the International Centre for Dispute Resolution shall appoint all three (3) arbitrators.
Place of Arbitration. Unless otherwise agreed by all Parties to the Dispute in writing, the place of arbitration shall be in the city of Denver, Colorado. Each Party irrevocably and unconditionally waives any objection that it may now or hereafter have to arbitration in the city of Denver, Colorado and any defense of an inconvenient forum to the maintenance of arbitration in such jurisdiction.
Language of Arbitration. The arbitration proceedings shall be conducted in the English language and the arbitrators shall be fluent in the English language.
Taking of Evidence. The taking of evidence with respect to the arbitration shall be governed by the International Bar Association Rules on the Taking of Evidence in International Commercial Arbitration, as adopted on June 1, 1999.
Impartiality. All arbitrators shall be and remain at all times wholly impartial, and, once appointed, no arbitrator shall have any ex parte communications with any of the Parties to the Dispute concerning the arbitration or the underlying Dispute.
Interim Measures. Any Party to a Dispute, at any time and from time to time, may apply to any court of competent jurisdiction for interim measures and interim relief: (i) upon the occurrence of an Event of Default; (ii) prior to or concurrently with the delivery of a Notice of Dispute, or at any time thereafter; (iii) prior to or concurrently with the constitution of the arbitral tribunal, or at any time thereafter, including as necessary to enforce the arbitral tribunal's rulings; or (iv) in the absence of the jurisdiction of the arbitral tribunal to rule on interim measures or interim relief in a given jurisdiction. The Parties agree that seeking and obtaining interim measures and interim relief shall not waive the right to arbitration, and the right to arbitration shall not waive or limit such interim measures and interim relief. The arbitrators (or in an emergency the presiding arbitrator acting alone in the

ZEQ.=3,SEQ=88,EFW="2217804",CP="URANIUM RESOURCES INC.",DN="1",CHK=784237,FOLIO='blank',FILE='DISK106:[13ZDG1.13ZDG18501]LY18501A.;14',USER='MVANGB',CD='13-DEC-2013;16:08'

event one (1) or more of the other arbitrators is unable to be involved in a timely fashion) may grant interim measures and interim relief, including injunctions, attachments, protective orders, restraining orders, temporary restraining orders and conservation orders in appropriate circumstances, which measures may be immediately enforced by court order by a court of competent jurisdiction. Hearings on requests for interim measures and interim relief may be held in person, by telephone, by video conference or by other means that permit the Parties to a Dispute to present evidence and arguments.

Judicial, Non-Judicial and Other Remedies. Notwithstanding any other provision of the Loan Agreement or any other Loan Document, nothing in the Loan Agreement or in this Schedule 11.8 or in any other Loan Document, nor the exercise of any right to arbitrate hereunder, shall waive, preclude, limit or prejudice the right of any Party hereto, whether judicially, non-judicially or otherwise, at any time and from time to time: (i) to foreclose against any real or personal property collateral, or any portion thereof, by the exercise of the power of sale under a deed of trust, mortgage, security agreement or other document, agreement or instrument or applicable law or the exercise of other foreclosure remedies, whether at law, in equity or otherwise, and to pursue and take all other actions related or ancillary to such foreclosure and sale; (ii) to exercise any and all self-help remedies, including setoff or repossession; (iii) to obtain any and all provisional or ancillary remedies, including replevin, injunctive relief, attachment, protective orders, restraining orders, temporary restraining orders, specific performance or appointment of a receiver, receiver and manager, administrator, trustee, controller, liquidator or other similar person, from a court having jurisdiction; (iv) to take, pursue, exercise or enforce any other right or remedy provided in any Security Document, whether in and before an appropriate court as required by applicable Governmental Requirements, through self-help, non-judicially or otherwise, whether before, during or after the pendency of any arbitration proceeding; or (v) to enforce any judgment or award made by the arbitrators. The institution and maintenance of any action for such judicial relief, or pursuit of provisional or ancillary remedies, or exercise of non-judicial and self-help remedies are available to the Parties without limitation and shall not constitute a waiver of the right or obligation of any Party to submit any Dispute to arbitration, including those Disputes arising from exercise of any judicial relief, or pursuit of provisional or ancillary remedies or exercise of non-judicial or self-help remedies. All rights and remedies enumerated herein are cumulative, and no right or remedy contained herein is intended to be exclusive. The enumeration of certain rights and remedies herein is not intended to, and shall not be deemed to, limit, restrict, waive or prejudice any right or remedy set forth in any other Loan Document.
Consolidation. If the Parties initiate multiple arbitration proceedings, the subject matters of which are related by common questions of law or fact and which could result in conflicting awards or obligations, then all such proceedings may be consolidated into a single arbitral proceeding.
Costs and Attorneys' Fees. The arbitral tribunal is authorized to award costs and attorneys' fees and to allocate them between the Parties to the Dispute. The costs of the arbitration proceedings, including attorneys' fees, shall be borne in the manner determined by the arbitral tribunal.
Interest. The award shall include interest, as determined by the arbitral tribunal, from the date of any Default, Event of Default or other breach of the Loan Agreement until the arbitral award is paid in full. Interest shall be awarded at the Applicable Interest Rate.
Currency of the Award. The arbitral award shall be made and payable in United States Dollars, free of any Tax or other deduction.
Following the Law and Agreement. The arbitrators have no authority to make any ruling, finding, or award (i) that does not conform to the terms and conditions of any agreement that is the subject of a Dispute hereunder, or (ii) that would result in the application of any law other than the laws of the State of Colorado (or such other governing law expressly provided in any Loan Document), without regard to any choice or conflicts of law provisions or rule that would cause the application of the law of any jurisdiction other than the foregoing.

Entry of Judgment. The award of the arbitral tribunal shall be a reasoned written decision and shall be final and binding. Judgment on the award of the arbitration tribunal may be entered and enforced by any court of competent jurisdiction.
Waiver of Challenge to Decision or Award. To the extent permitted by law, any right to appeal or challenge any arbitral decision or award, or to oppose enforcement of any such decision or award before a court or any governmental authority, is hereby waived by the Parties.
Confidentiality. All negotiations, mediation, arbitration, and expert determinations relating to a Dispute (including a settlement resulting from a negotiation, an arbitral award, documents exchanged or produced, and memorials, briefs or other documents prepared for the arbitration) are confidential and may not be disclosed by the Parties, their employees, officers, directors, counsel, consultants and expert witnesses, except to the extent necessary to enforce any arbitration award, to enforce other rights of a Party, or as required by any Governmental Requirement; provided, however, that breach of this confidentiality provision shall not void any settlement, expert determination or award.
