                Second Kingsville Dome and Rosita Mines Agreement

     This Agreement is entered into by the Texas Natural Resource Conservation
Commission ("TNRCC"), the Texas Department of Health ("TDH"), URI, Inc. ("URI")
and the United States Fidelity & Guaranty Company ("USF&G") on January 1, 2002
and shall run until April 30, 2002.

                                    Recitals

A.   URI is the owner and operator of the Kingsville Dome and Rosita Mines
located in Kleberg and Duval Counties, Texas, respectively.

B.   The following are the outstanding Bonds issued by USF&G on behalf of the
Kingsville Dome and Rosita Mines to provide assurance that funds will be
available when needed for groundwater restoration, decommissioning, and, if
applicable, for the long term care of the facility. By this Agreement, the
Agencies agree that they cannot enforce in excess of the amounts set forth below
against USF&G:

     On June 23, 2000, USF&G issued to TDH on behalf of the Kingsville Dome Mine
the Surety Bond Rider to Performance Guarantee Bond (Bond No.41-0130-40028-96-6)
that has been in effect since December 2, 1996, in the penal sum of One Million
Seven Hundred Forty One Thousand Five Hundred Forty Two Dollars ($1,741,542.00).
The agencies acknowledge their continued obligations under the prior Kingsville
Dome and Rosita Mines Agreement with respect to the reduction of bond amounts
for the final quarter of the prior Agreement.

     On June 23, 2000, USF&G issued to TDH on behalf of the Rosita Mine the
Surety Bond Rider to Performance Guarantee Bond (Bond No. 41-0130-40040-96-6)
that has been in effect since November 26, 1996, in the penal sum of One Million
Nine Hundred Nine Thousand Six Hundred Forty Three Dollars ($1,909,643.00). The
agencies acknowledge their continued obligations under the prior Kingsville Dome
and Rosita Mines Agreement with respect to the reduction of bond amounts for the
final quarter of the prior Agreement.

C.   URI, to induce USF&G, as Surety, to execute the Bonds on behalf of URI,
executed and delivered a Master Surety Agreement for the benefit of Surety,
dated November 25, 1996, pursuant to which URI, agreed to exonerate, hold
harmless, indemnify and keep indemnified USF&G from and against any and all
demands, claims, liabilities, losses and expenses of whatsoever kind or nature
(including but not limited to, interest, court costs and counsel fees) imposed
upon, sustained, or incurred by USF&G by reason of: (1) USF&G having executed,
provided or procured Bonds in behalf of URI, Inc., or (2) URI, Inc.'s failure to
perform or comply with any of the provisions of the Master Surety Agreement. By
this document, URI, Inc. reaffirms its indemnity obligations under the Master
Surety Agreement.

D.   This Agreement is entered by USF&G and the Agencies at the request of URI,
which has acknowledged that it is financially unable to meet its obligations to
continue groundwater restoration of the Kingsville Dome and Rosita Mines without
this Agreement. This Agreement does not replace or supersede any licenses,
permits, or regulatory requirements already in place. It is not intended that
the terms of this Agreement affect or change the responsibilities of TDH and
TNRCC as set forth in the Memorandum of Understanding between the agencies found
at 25 TAC Sec. 289.101(f).

E.   USF&G may have certain defenses to claims made under the Bonds, and it
expressly reserves any and all defenses it may have or hereinafter acquire.

F.   The purpose of this Agreement is, variously, to (1) protect the public
health and environment by facilitating the implementation and continuation of
groundwater restoration of the Mines; (2) provide a mechanism for USF&G to
receive an equivalent reduction in the penal sum of its liability under the
Bonds in consideration of USF&G's funding of groundwater restoration costs of
the Mines.

3.   Funding of Operations. USF&G agrees, subject to the provisions contained
herein, to fund reasonable restoration costs at the Kingsville Dome Mine and
Rosita Mine as enumerated in Appendix A attached to and by this reference
incorporated in this Agreement. In the event that URI is able to secure funds
outside of USF&G, other than funds provided by URI's investor group that are
specifically designated for general and administrative costs, other holding
costs and/or for the resumption of production operations, URI will notify the
TDH and TNRCC for a determination if these funds should be used to substitute or
supplement funding by USF&G. In the event URI secures investor group funding
during the term of this Agreement, URI shall provide the TDH and the TNRCC with
a summary of the expenditures made from such investor group funding.

4.   Period of Funding/Term of Agreement. This Agreement shall remain in force
and effect from its effective date until April 30, 2002. In the event URI fails
to meet the performance Criteria set forth in Appendix B for a specific month
and such Performance Criteria are not waived by the Agencies, the Agencies may
terminate the Agreement with 10 days notice to URI. If the Agencies terminate
the Agreement they shall notify USF&G of such action. This notification shall
occur within 24 hours upon termination of the Agreement, and will be effective
upon receipt by USF&G.

5.   Force Majeure. URI shall not be deemed as failing to meet the Performance
Criteria for a specific month due to any Act of God, war, strike, riot,
electrical outage, accident, fire, explosion, flood, blockade, or other
catastrophe hereafter "force majeure," beyond URI's reasonable-control. In the
event of such force majeure, URI shall notify the Agencies of the event within
24 hours. Should such force majeure prevent or

                            Page 2 of Exhibit 10.19

<PAGE>

reduce groundwater restoration activities for the subsequent month, then the
Agencies may terminate the Agreement with 10 days notice to URI.

6.   Record Keeping. URI shall include a summary of all reasonable restoration
costs incurred during a month in the monthly performance reports to the
Agencies. URI will maintain complete records of reasonable expenditures made
during the term of this Agreement and will make those records available upon
request from the Agencies for auditing purposes.

     URI shall maintain and make available to the Agencies upon request, records
of its groundwater restoration activities at the Mines. These records shall
include: 1) accurate and legible maps of well fields and well locations; and 2)
accurate and up to date well completion and maintenance information.

7.   Capital Allowance. USF&G agrees, subject to the provisions contained
herein, to fund $45,000 as reasonable restoration costs, for additional reverse
osmosis water treatment equipment to be installed on the remote ion exchange
equipment located in Production Area 3 at the Kingsville Dome location ("PAA3")
as enumerated in Appendix A attached to and by this reference incorporated in
this Agreement. Once functional, this equipment shall be used to conduct
restoration in PAA3 over the term of this Agreement. PAA3 restoration shall be
concurrent with the restoration operations at the remainder of the Kingsville
Dome mine. The restoration operation cost of PAA3 equipment shall be included in
the amounts enumerated in Appendix A and shall only be allowed in any month if
the Reverse Osmosis unit at PAA3 is operational in that month.

8.   Security and Electricity Advance Payment. URI shall make a payment to the
Texas Department of Health Bureau of Radiation Control in the amount of $37,500
to provide for site security and electrical power requirements for three months
of groundwater restoration operations in the event that groundwater restoration
operations cease at the mines before groundwater restoration is completed. This
advance payment shall be made by URI within 10 days of receipt from USF&G. This
advanced security and electrical payment shall be included in the amounts
enumerated in Appendix A and be subject to appropriate bond reduction for each
location. URI stipulates that this advance payment is not, and shall not be,
assets of URI, Inc.'s bankruptcy estate.

9.   Progress Reports, Bond Reduction and Future Payments to URI, Inc. On
January 31, 2002 and each month thereafter as set forth in Appendix C, TDH will
provide USF&G with a written bond reduction notice ("bond reduction notice") in
the format attached hereto as Appendix D. It is agreed by TDH that it will issue
the bond notice reduction within 10 working days following the end of the month
contingent upon receiving USF&G's certification of monthly advances to URI. The
failure to do so shall constitute a material breach of this Agreement for which
USF&G would thereafter have no further obligation to provide any further funding
pursuant to this Agreement

     The bond reduction notice will reduce the penal amount of the bonds on a
dollar for dollar basis for restoration costs paid during the previous period.
Penal sum reductions will be allocated to the appropriate bonds for the
appropriate projects. Under no circumstance will the bond reduction for a
preceding month exceed the reasonable restoration cost projections in Appendix
A. URI shall provide a monthly groundwater restoration progress report in
accordance with Appendix B, to the Agencies for each month no later than the
10th working day of the following month. The TDH shall notify URI and USF&G of
the appropriate monthly bond adjustment. Failure to perform on the part of URI
shall mean the failure to operate within agreed upon reasonable restoration cost
projections within Appendix A or the failure to meet the Performance Criteria in
Appendix B. If the Agencies, with good cause, disapprove URI's performance, or
reasonable restoration costs, the TDH may adjust the next month's bond reduction
amount. At the conclusion of the last month, the Agencies shall not reduce the
bond amount until they have completed the performance and financial reviews of
the last month's data.

10.  Reconciliation of Expenses. Upon receipt of a monthly performance or
progress report, the Agencies may review all costs and expenditures. The
Agencies may require additional information from URI regarding expenses. No
expenses in excess of those detailed in Appendix A shall be eligible for

                            Page 3 of Exhibit 10.19

<PAGE>

reimbursement under this Agreement unless they have been authorized in advance,
in writing, for a specific amount, by the TNRCC prior to the expenditure being
made by URI. Upon the advance approval in writing of such costs by TNRCC, such
costs will be eligible for inclusion of funding to URI by USF&G. If approval is
not obtained such costs are not eligible for inclusion of funding to URI by
USF&G. Upon funding by USF&G such costs would be treated comparably to all other
costs shown on Appendix A regarding their eligibility for bond reductions by
USF&G.

11.   Periodic Reporting by USF&G. Contemporaneously with funding, USF&G will
provide to TNRCC and TDH a certification of monthly advances under this
Agreement to URI by the end of each month.

12.   Surety Not an Owner or Operator. USF&G shall not be an "owner" or
"operator" of the Mines by virtue of execution and delivery of and performance
of its obligations under this Agreement. The parties' execution and delivery of
this Agreement is not intended to make USF&G an "owner" or "operator." USF&G's
role as Surety will not in any way make it responsible for any operation of the
Mines, nor will it own any part of the Mines.

12.a. Agencies not an Owner or Operator. TNRCC or TDH shall not be an " owner"
or "operator" of the Mines by virtue of execution and delivery of and
performance of their obligations under this Agreement. The parties' execution
and delivery of this Agreement is not intended to make TNRCC or TDH an "owner"
or "operator." TNRCC's or TDH's role in approving bond reductions will not in
any way make it responsible for any operation. of the Mines, nor will it own any
part of the Mines.

13.   Reservation of Defenses. USF&G's execution, delivery and performance under
this Agreement shall not constitute, nor be deemed to constitute, an admission
of liability or a waiver of any claims or defenses which USF&G may assert or
have against URI, Inc., any indemnitors, or against claims made against USF&G
under the Bond. The Agencies' execution, delivery or performance under this
Agreement shall not constitute, nor be deemed to constitute, an admission of
liability or waiver of any claims or defenses which the Agencies may assert or
have against URI, Inc. relative to the Kingsville Dome and/or Rosita Mines, or
USF&G.

14.   Bankruptcy of URI.

      14.1  It is the express desire, intent, and agreement of the parties
      (TNRCC/TDH, URI and USF&G) that in the event URI shall become a Debtor in
      a bankruptcy proceeding (by virtue of either the commencement of a
      voluntary or an involuntary petition) the rights of TNRCC/TDH and USF&G
      shall remain as unaffected as possible with respect to their mutual
      obligations under these Bonds. Accordingly, as a material element of this
      Agreement, the parties expressly agree and covenant as follows:

      14.2. URI will enter into a Stipulation satisfactory to TNRCC/TDH and
      USF&G setting forth sufficient facts to demonstrate its acknowledgment
      that the parties would not have entered into this Agreement absent such
      stipulation. The Stipulation shall further recite that, should URI become
      a Debtor in a Chapter 11 bankruptcy proceeding, it shall elect at the
      earliest of (1) sixty (60) days from the Petition date or (2) thirty (30)
      days from the entry of the Order for Relief in the instance where an
      involuntary petition is commenced to assume or reject this Agreement as an
      executory contract.

      14.3  URI and USF&G further agree that they shall take no action directly
      or indirectly to prevent the Bankruptcy Court from ordering URI to make
      such an accelerated election regarding assumption or rejection of this
      Agreement in accordance with the time frame set forth above in paragraph
      14.2.

      14.4. In the event URI elects to assume this executory contract, URI shall
      cure any pending defaults within 30 days of the date it makes said
      election to assume (irrespective of the date of the

                            Page 4 of Exhibit 10.19

<PAGE>

     entry of the Order approving assumption). In the event the Bonds are
     called, USF&G shall be entitled to a full credit against the face amount of
     the Bonds for any partial payments distributed previously to URI in
     accordance with this Agreement.

     14.5.  In the event URI elects to reject this executory contract, the
     parties agree that each will have whatever rights and obligations they have
     under this Agreement, the Bonds, and applicable law.

     14.6.  All parties further acknowledge that the obligation of USF&G under
     these Bonds constitutes an independent obligation of USF&G as a surety in
     favor of TNRCC/TDH. URI further covenants that in its legal opinion, should
     URI become a debtor in a bankruptcy proceeding, that these Bonds constitute
     independent obligations of USF&G and would not constitute assets of URI's
     bankruptcy estate. URI further covenants that it shall take no action
     either directly or indirectly to controvert any position taken in the
     Bankruptcy Court by TNRCC/TDH that these Bonds are not property of URI's
     bankruptcy estate.

     14.7.  URI and USF&G acknowledge that there have been extensive
     confidential settlement communications, privileged under Federal Rule of
     Evidence 408, leading up to the execution of this Agreement. URI, USF&G,
     and TNRCC/TDH further covenant that they shall never seek to introduce
     evidence of any prior negotiations that led up to this Agreement (by way of
     example but not by limitation, introduction of previous drafts of this
     settlement agreement as parole evidence).

     14.8  In the event of the bankruptcy of URI, the parties to this Agreement
     stipulate that the groundwater restoration equipment located at the
     Kingsville Dome and Rosita mines may continue to be used for groundwater
     restoration activities until the groundwater restoration is completed.

15.  Notices. Any notices required or authorized to be given by this Agreement
shall be in written form. Any notices required or authorized to be given by this
Agreement must be sent by: (a) registered or certified delivery mail, postage
prepaid and return receipt requested, addressed to the proper party at the
following address or such address as the party shall have designated to the
other parties in accordance with this Section; or (b) personal delivery. Mailed

B-1.     Kingsville Dome Mine

..    QUANTITY PERFORMANCE. Prior to April 1, 2002, URI shall perform at a rate
     --------------------
     of at least 80% of the instantaneous design rate for the installed
     equipment at Kingsville Dome based on the calculations outlined below. The
     rate at which water is treated is calculated by adding the waste disposal
     well flow to the RO feed flow and subtracting the RO brine:

               WDW 248 maximum average permitted flow: 200 gal/min
                    RO feed rate design maximum: 585 gal/min
             Less RO brine contribution to WDW 248 flow: 146 gal/min

      [WDW max + RO max - brine amount =maximum water treated: 639 gal/min]

              (639 gal/min x 1440 min/day x 30 days/mth) x 0.80 =
                        22.1 million gallons per month)

     Starting April 1, 2002, URI shall perform at a rate of at least 80% of the
     instantaneous design rate for the installed equipment at Kingsville Dome
     based on the calculations outlined below.

               WDW 248 maximum average permitted flow: 200 gal/min
                    RO feed rate, design maximum: 785 gal/min
             Less RO brine contribution to WDW 248 flow: 196 gal/min
     [WDW max + RO max - brine amount -- maximum water treated: 789 gal/min]

               (789 gal/min x 1440 min/day x 30 days/mth) x 0.80 =
                        27.3 million gallons per month)

..    QUALITY PERFORMANCE. Quality performance shall be assessed on a PAA by PAA
     -------------------
     basis using groundwater analysis to gauge restoration progress. To allow
     the state staffs to evaluate restoration progress in terms of improvements
     in water quality, URI shall do the following:

          Collect water quality data at least once every two weeks from each
          extractor well in the areas currently under active restoration; data
          shall at a minimum include Conductivity, (or TDS), uranium (as
          U\\3\\O\\8\\), Ca, pH, and SO\\4\\.

          At least one time during the term of this Agreement, collect water
          quality data as described above from all production area baseline
          wells in areas previously considered restored. In addition, other
          wells, as selected by the Commission, shall be sampled for Radium-226.

          Submit water quality sampling data in both tabular and graphic form to
          facilitate comparison to past restoration progress reports,

          Submit restoration water quality progress reports monthly.

     Determination of final restoration shall be done in accordance with
     standard state procedures, as found in 30 TAC 331.107. Before final
     restoration is confirmed, URI shall obtain stability samples from all
     production area baseline wells and analyze for those parameters listed in
     the restoration table

B-2. Rosita Mine

..    QUANTITY PERFORMANCE. URI shall perform at a rate of at least 80% of the
     --------------------
     instantaneous design rate for the installed equipment at Rosita. The rate
     at which water is treated is calculated by adding the waste disposal well
     flow to the RO feed flow and subtracting the RO brine:

                  WDW 250 maximum average capacity: 150 gal/min
                    RO feed rate, design maximum: 585 gal/min
             Less RO brine contribution to WDW 250 flow: 146 gal/min
    [WDW max + RO max - brine amount = maximum water treated : 589 gal/min]

                 STIPULATION OF URI, INC., THE TEXAS DEPARTMENT
             OF HEALTH, AND THE TEXAS NATURAL RESOURCE CONSERVATION
                       COMMISSION REGARDING CERTAIN FACTS

URI, Inc., ("URI"); the Texas Department of Health, ("TDH"); and the Texas
Natural Resource Conservation Commission, ("TNRCC") by and through their
respective counsel, stipulate as follows:

1.   URI holds TDH Radioactive Material License L03653 and TNRCC Underground
Injection Control Permits UR02827 (Kingsville Dome Mine) and UR02890 (Rosita
Mine) authorizing its in situ uranium mining operations in Kleberg and Duval
Counties, Texas.

2.   Nothing in this stipulation changes, modifies, or amends any license,
permit, or production area authorization requirement.

3.   Because URI was financially unable to continue ground water restoration at
the Kingsville Dome and Rosita Mines, the Kingsville Dome and Rosita Mines
Agreement and subsequent Second Kingsville Dome and Rosita Mines Agreement was
executed by URI, TDH, TNRCC, and United States Fidelity and Guaranty Company
("USF&G").

4.   Under the terms of the Kingsville Dome and Rosita Mines Agreement and
Second Kingsville Dome and Rosita Mines Agreement, URI received funding from
USF&G to pay for reasonable restoration costs at the Kingsville Dome and Rosita
Mines. The financial assurance bonds (Performance Guarantee Bond No.
41-0130-40028-96-6 and Performance Guarantee Bond No. 41-0130-40040-96-6,
hereinafter "Bonds") for groundwater restoration issued to TDH by USF&G on
behalf of URI have been reduced according to the terms of the Kingsville Dome
and Rosita Mines Agreement and Second Kingsville Dome and Rosita Mines
Agreement.

5.   As a material element of the Second Kingsville Dome and Rosita Mines
Agreement, URI agreed to enter this stipulation.

6.   The TDH and TNRCC would not have executed the Second Kingsville Dome and
Rosita Mines Agreement without this stipulation.

7.   URI shall elect at the earliest of (1) sixty days from the Petition date or
(2) thirty days from the entry of the Order for Relief in the instance where an
involuntary petition is commenced to assume or reject the Second Kingsville Dome
and Rosita Mines Agreement as an executory contract.

8.   URI shall take no action directly or indirectly to prevent the Bankruptcy
Court from ordering URI to make such an accelerated election regarding
assumption or rejection of the Second Kingsville Dome and Rosita Mines Agreement
in accordance with the time frame set forth above in paragraph 7.

9.   Should URI elect to reject the Second Kingsville Dome and Rosita Mines
Agreement as an executory contract, the TDH/TNRCC will retain whatever rights
and obligations they have under the Bonds, including the right to call in the
bonds for performance or payment.

10.  All parties acknowledge that the obligations of USF&G under the Bonds
constitutes an independent obligation of USF&G as a surety in favor of
TDH/TNRCC.

11.  URI covenants that in its legal opinion the Bonds constitute an independent
obligation of USF&G and do not constitute assets of URI's bankruptcy estate.

12.  URI covenants that it shall take no action either directly or indirectly to
controvert any position taken in the Bankruptcy Court by TNRCC/TDH that these
Bonds are not property of URI's bankruptcy estate.

URI, INC.                                       DEPARTMENT OF HEALTH

                                                AUSTIN, TEXAS

                                  AGREED ORDER
                                  ------------

                                 I. JURISDICTION

The Texas Department of Health ("Department" or "TDH") is authorized to enforce
Tx. Health and Safety Code Chapter 401, ("Act") and the Department's rules found
at 25 Tex. Admin. Code Chapter 289 ("Rules") relating to the regulation of
sources of radiation, including in situ uranium mines. The Texas Natural
Resource Conservation Commission ("TRNCC") also has jurisdiction over the
operation of in situ uranium mines. The Department is the lead agency for
enforcing the financial security requirements regarding in situ uranium mines
under 25 Tex. Admin. Code (S) 289.101(f).

                                 II. RESPONDENT

URI, Inc. ("URI") possesses a radioactive materials license from the Department
and is subject to the aforementioned Act and Rules. URI's license no. L03653
covers the Kingsville Dome mine in Kleberg County and the Rosita and Vasquez
mines located in Duval Counties whose locations are more particularly described
in the license. URI is not currently engaged in the mining of uranium (except
the incidental removal of uranium during the groundwater restoration process).

                                   III. FACTS

On January 8, 2002, the Department, the TNRCC, URI and United States Fidelity &
Guaranty Company executed the Second Kingsville Dome and Rosita Mines Agreement.
This Agreement acknowledged that URI has serious financial difficulties in
meeting its obligations. On January 16, 2002, based upon a review of financial
security, the Department's Bureau of Radiation Control ("BRC") requested that
URI post additional financial security under its license and threatened
enforcement action against URI if it failed to post the additional financial
security. URI is unable to post the additional financial security at this time.

                                  IV. RESPONSE

URI responded to the Department's request letter by filing an objection and
requesting a conference to attempt to resolve the matter.

                                 VI. SETTLEMENT

Discussions were held between representatives of the Department and URI and a
settlement was reached. This settlement, the terms of which are contained in
this Agreed Order, is based on the desire of the Department to see that
appropriate and cost effective restoration and decommissioning of URI's mine
sites occurs. The TNRCC was notified of the discussions and the settlement
agreed upon by the Department and URI.

                            Page 1 of Exhibit 10.20

<PAGE>

                            VII. COMPLETE SETTLEMENT

The terms contained herein are the complete settlement of all current issues
regarding URI's financial security under its license.

             A. WAIVER OF HEARING AND AGREEMENT REGARDING SIGNATURE

In exchange for the execution of this Agreed Order, URI waives any right to a
hearing. URI agrees that this Order may be signed by the Commissioner of Health
or his designee.

                  B. NO WAIVER WITH REGARD TO FUTURE VIOLATIONS

The Department does not waive the right to take legal action against URI for any
future violations of TDH rules or its license which may be committed by URI.

                            C. COMPLETE UNDERSTANDING

URI acknowledges that it understands the terms of this settlement, enters into
the settlement freely, and agrees to the terms of this order.

                              D. NO RIGHT TO APPEAL

URI waives the right to judicial review of this Order.

IT IS, THEREFORE, ORDERED that the deadline for URI to post additional financial
security for its mine sites is extended for 365 days from the date of this Order
so long as the following conditions are met by URI:

     1.   URI shall not conduct any mining of uranium at its mines (except the
          incidental removal of uranium during the groundwater restoration
          process) during this period of time, unless additional financial
          security for its license is approved by and posted with the Department
          in consultation with the TNRCC;
     2.   URI shall not conduct any mining at its mines (except the incidental
          removal of uranium during the groundwater restoration process), unless
          authorized by appropriate permits issued by the TNRCC;
     3.   URI shall be in substantial compliance with TDH License No. L03653 and
          all permits issued by the TNRCC, including Nos. UR02827-001,
          UR02880-001 and UR03050-001;
     4.   URI shall fully cooperate with all inspections by the Department and
          the TNRCC and provide all information requested by either agency;
     5.   In the case of its bankruptcy, URI shall allow the groundwater
          restoration equipment located at the mines to be used for groundwater
          restoration activities until groundwater restoration is complete.
