                   KINGSVILLE DOME AND ROSITA MINES AGREEMENT

         This Kingsville Dome and Rosita Mines Agreement ("Agreement") is
entered by and among 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").

                                    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).

         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).

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 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.

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) facilitate 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.

Now, therefore, the parties agree as follows:

1.       INCORPORATION. The above Recitals are hereby incorporated into this
Agreement.

2.       DEFINITIONS. The following terms shall have the meanings defined below:

         1.1 "Agencies" means collectively TNRCC and TDH.

<PAGE>   2

         1.2 "Bonds" means the Bonds described in Recital B.

         1.3 "Restoration Costs" means any reasonable costs directly associated
with or necessary for groundwater restoration activities at the Mines. Costs
that would not be allowed for bond reduction include, but are not limited to:
salaries of personnel for time not directly relating to groundwater restoration
at the Kingsville Dome and Rosita mines; travel to or activities regarding other
URI sites; general and administrative costs; other holding costs; legal costs;
costs of contesting TNRCC or TDH actions; and/or costs for the resumption of
production operations.

         1.4 "Effective Date" means the date on which this Agreement has been
executed by all of the parties.

         1.5 "Mines" means the Kingsville Dome Mine and the Rosita Mine.

         1.6 "Surety" means United States Fidelity & Guaranty Company.

         1.7 "TDH" means the Texas Department of Health.

         1.8 "TNRCC" means the Texas Natural Resource Conservation Commission.

         1.9 "URI" means URI, Inc.

         1.10 "USF&G" means the United States Fidelity & Guaranty Company.

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

                                       2
<PAGE>   3

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.

4. PERIOD OF FUNDING/TERM OF AGREEMENT. This agreement shall remain in force and
effect from its effective date until December 31, 2001. In the event URI fails
to meet the Performance Criteria set forth in Appendix B for a specific
quarterly period 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 quarter 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 reduce groundwater restoration
activities for the subsequent quarter, 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 quarter in the quarterly 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.

7. INITIAL PAYMENT BY USF&G. USF&G is to pay the sum of $451,750 for groundwater
restoration cost expenses and for capital expense for the reverse osmosis unit
equipment at the Rosita Mine to be incurred during the period from July 1, 2000
through September 30, 2000, as shown in Appendix A. Such payment is to be made
to URI on a periodic basis. TDH and TNRCC stipulate and agree that USF&G's
obligations under the Bonds shall be reduced, dollar for dollar on October 2,
2000 for each amount USF&G has paid to URI, up to $451,750 during the period
from July 1, 2000 through September 30, 2000 at the Kingsville Dome and Rosita
Mines.

8. PROGRESS REPORTS, BOND REDUCTION AND FUTURE PAYMENTS TO URI, INC. On
September 30, 2000 and each calendar quarter 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 calendar quarter contingent upon receiving USF&G's certification of
quarterly advances to URI by the end of the calendar quarter, and 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.

                                        3
<PAGE>   4

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 quarter
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 of the first two months of each quarter no
later than the 10th working day of the following month. Commencing on September
30, 2000 and every three months thereafter until December 31, 2001, or by the
amendment and extension of this Agreement by the parties, URI shall provide
within 10 working days of the end of each calendar quarter to all parties, a
quarterly report documenting groundwater restoration activities conducted and
costs associated therewith that have occurred during that quarter. The TDH shall
notify URI and USF&G of the appropriate quarterly 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 quarter's bond reduction amount. At the conclusion of the last
quarter, the Agencies shall not reduce the bond amount until they have completed
the performance and financial reviews of the last quarter's data.

9. RECONCILIATION OF EXTRAORDINARY EXPENSES. Upon receipt of a quarterly
performance or progress report, the Agencies may review all costs and
expenditures. The Agencies may require additional information from URI regarding
extraordinary expenses. Although USF&G will receive a reduction in the bonds'
penal sum, dollar for dollar, for costs paid during the previous period, upon
identification and validation of these extraordinary expenses by the Agencies,
the bond reductions will be adjusted in a following quarter for expenses
disallowed by the Agencies.

10. PERIODIC REPORTING BY USF&G. Contemporaneously with funding, USF&G will
provide to TNRCC and TDH a certification of quarterly advances under this
Agreement to URI by the end of each calendar quarter.

11. 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. 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.

13. BANKRUPTCY OF URI.

         13.1 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:

         13.2. 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.

         13.3. 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 13.2.

         13.4. 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 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.

         13.5. 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.

         13.6. 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.

         13.7. URI and USF&G acknowledge that there have been extensive
confidential settlement communications, privileged under Federal Rule of
Evidence 408, leading up to the

                                        5

<PAGE>   6

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. 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

2.1 Organization. The Company is a duly domesticated and validly existing
corporation in good standing under the laws of the state of Delaware with all
necessary corporate power to enter into and perform this Purchase Agreement,
issue and sell the Shares and carry on the business now conducted by it. The
Company is duly qualified and in good standing as a foreign corporation in all

property owned by it makes such qualification necessary, and is duly authorized,
qualified and licensed under all laws, regulations, ordinances or orders of

presently conducted.

         All necessary corporate proceedings have been taken by the board of
directors of the Company to authorize the execution, delivery and performance of

required by the stockholders of the Company in connection with the execution,
delivery and performance of this Purchase Agreement, except approval of an

to issue, which approval will be solicited promptly following the date of this
Agreement. The Agreement has been duly authorized, executed and delivered and is
enforceable against the Company in accordance with its terms. Upon issuance of
the Shares at the Closing after receipt of the consideration to be paid for the
Shares and approval of the stockholders to the increase in the authorized Common
Stock to 100,000,000, the Shares will be duly authorized, validly issued, fully
paid and non-assessable.

         2.2 No Legal Obstacle. Neither the consummation of the transactions
contemplated by this Purchase Agreement nor compliance with the provisions of
this Purchase Agreement nor issuance of the Shares, will result in any breach or
violation of any of the provisions of, or constitute a default under, the
Restated Certificate of Incorporation or by-laws of the Company, in each case as
amended through the Closing Date, or any provision of law, agreement or other
instrument which will remain in effect after the issue and sale of the Shares
and to which the Company is a party or by which it is bound, or of any
applicable order or regulation of any governmental authority having
jurisdiction, or result in the creation under any other agreement or instrument
of any lien or encumbrance upon any assets of the Company.

         2.3 Tax Returns. The Company and its Subsidiaries have filed all
federal, state and local tax returns which are required to be filed and have

the transactions contemplated herein have been carried on by the Company
directly with the Purchasers listed on Schedule II hereto and with Zesiger
Capital Group LLC on behalf of the Purchasers listed on Schedule I hereto in
such manner as not to give rise to any valid claim against the Company for a

actions, suits or proceedings, at law or in equity, and no proceedings before
any arbitrator or by or before any governmental commission, board, bureau or

threatened, against or affecting the Company, any Subsidiary, or any properties

materially impair the right of the Company or any Subsidiary to carry on
business substantially as now conducted or could have a material adverse effect
upon the Company and the Subsidiaries individually, or taken as a whole.

         2.9 Financial Statements. Except as set forth in the Company's Annual
Report on Form 10-K for the year ended December 31, 1999, the audited and
unaudited financial statements contained therein and in the Company's quarterly

statements") have been prepared in accordance with generally accepted accounting
principles consistently applied, except as otherwise indicated in such financial
statements or in an auditor's report with respect thereto included in such Form
10-K, and present fairly the financial condition of the Company and its

Subsidiary has any material contingent obligations, liabilities for taxes,
long-term leases or unusual forward or long-term commitments not disclosed by,
or reserved against, in the financial statements.

         2.10 Compliance with Other Agreements. Neither the Company nor any
Subsidiary is in default nor, except as set forth in the Company's Annual Report
on Form 10-K for the year ended December 31, 1999, has any event or circumstance
occurred which, but for the passage of time or the giving of notice, or both,
would constitute a default under any material agreement to which it is a party
which could reasonably be expected to have a material adverse effect on the
Company and its Subsidiaries taken as a whole.

         2.11 Compliance with Laws. Neither the Company nor any Subsidiary (i)
is in material violation of any law, rule, order, regulation of any kind or any
other governmental requirement, including environmental laws and ERISA (as
hereinafter defined); or (ii) has failed to obtain any license, permit,
franchise or other governmental authorization necessary to the ownership of any
of its respective properties or the conduct of its respective business; except
such violations and failures which could not reasonably be expected to have in
the aggregate (in the event that such violation or failure was asserted by any
person through appropriate action) a material adverse effect on the Company and
its Subsidiaries taken as a whole.

         2.12 ERISA etc. The Company has no employee benefit plan that is
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), except for the Company's 401k Plan and cafeteria medical plan. The
Company has complied with all of its obligation with respect to such plans.

3. Representations; Warranties and Acknowledgments of the Purchasers.

         3.1 Purchase for Investment. Each of the Purchasers represents and
warrants to the Company that it will acquire the Shares to be purchased by it
for its own account for investment

<PAGE>   5

and not with a view to the distribution thereof, and that it has no present
intention of making any distribution or disposition of them; provided, however,
that the disposition of its property shall at all times be and remain within its
control. The acquisition of Shares by each of the Purchasers shall constitute
its confirmation of said representation and warranty. Each of the Purchasers
understands that the Shares are being sold to it in a transaction which is
exempt from the registration requirements of the Securities Act of 1933, and
that the Shares must be held by it and may not be resold unless they are
subsequently registered under the Act or an exemption from such registration is
available. Each of the Purchasers further understands that the Shares will be
legended with a notation that they were acquired for investment in an exempt
transaction and that they may not be resold unless they are subsequently
registered under the Securities Act of 1933 or unless an exemption from such
registration is available.

         3.2 Risks. Each of the Purchasers acknowledges that this offering
involves significant risks, including the following:

                  (a) BANKRUPTCY RISK. Because of depressed uranium prices the
         Company in 1999 and the first quarter of 2000 ceased production
         activities in both of its two producing properties, monetized all of
         its remaining uranium sales contracts, and sold certain of its property
         and equipment to maintain a positive cash position. Since then, the
         Company currently has exhausted all of its available sources of cash to
         support continuing operations, and will be unable to continue in
         business beyond March 15, 2001 unless it can secure a cash infusion. As
         a result, if the Company is unable to complete this offering of the
         Shares or otherwise obtain a cash infusion in the near future it will
         most likely be forced to file for protection from its creditors under
         the Bankruptcy laws of the United States. Assuming that the Company is
         able to continue funding its restoration of the Kingsville Dome and
         Rosita mine sites through extensions to its agreement with Texas
         regulatory authorities and the Company's bonding company, the Company
         estimates that an infusion of $2.085 million from the private placement
         should provide it with the resources to remain operating into
         approximately the first quarter of 2003. In either case, additional
         funds will be required for the Company to continue operating after that
         date. The Company's current agreement with the Texas regulatory
         authorities and its bonding company extends through 2001. The Company
         cannot guarantee that it will be able to extend such agreement beyond
         2001, or that any extension of the agreement that is negotiated will
         contain the same terms and conditions as the current agreement.

                  (b) FINANCIAL STATEMENT RISK. Because of its financial
         condition, the Company, since 1998, has not been able to prepare
         audited financial statements for the purposes of this offering or
         otherwise. Therefore, any purchaser of the Shares assumes the risk that
         when the Company's unaudited financial statements are hereafter
         audited, audit adjustments to such financial statements may be
         material.

                  (c) OTHER RISK FACTORS. In addition, a Purchaser should
         carefully review the Risk Factors set forth in the Company's Form
         10-K/A for the year ended December 31, 1999.

         3.3. Accredited Investor Status. Each of the Purchasers represents and
warrants that he, she or it understands that the Company will rely upon the
following information for purposes of its determination that the Purchasers are
"accredited investors" (as that term is defined in Regulation D promulgated by
the SEC under the Securities Act of 1933, as amended), and that the Shares will
not be registered under the Securities Act in reliance upon one or more of the
exemptions from registration provided under the Securities Act and Regulation D
for nonpublic offerings. Each Purchaser represents and warrants that he, she or
it is an accredited investor by virtue of meeting one of the following
requirements:

<PAGE>   6

                  (a) If the Purchaser is an individual he or she had an
         individual income in each of the two most recent years and reasonably
         expects to have individual income in excess of $200,000 for the current
         year or a joint income with his or her spouse in excess of $300,000 in
         each of the two most recent years and reasonably expects to have joint
         income with such spouse in excess of $300,000 for the current year; or
         he or she currently has an individual net worth, or his or her spouse
         and he or she have a joint net worth, in excess of $1,000,000; or

                  (b) If the Purchaser is a trust it has total assets in excess
         of $5,000,000, was not formed for the specific purpose of acquiring the
         Shares, and the purchase of the Shares has been directed by a
         "sophisticated person" as defined in Rule 506(b)(2)(ii) of Regulation
         D, that is, a person who has such knowledge and experience in financial
         and business matters that he is capable of evaluating the merits and
         risks of an investment in the Shares.

                  (c) If the Purchaser is a partnership (i) it was not formed
         for the specific purpose of acquiring the Shares and has total assets
         in excess of $5,000,000, or (ii) all of its equity owners individually
         qualify as accredited investors.

                  (d) If the Purchaser is a limited liability company (i) it was
         not formed for the specific purpose of acquiring the Shares and has
         total assets in excess of $5,000,000, or (ii) all of its equity owners
         individually qualify as accredited investors.

         3.4 Receipt of Company Documents. Each Purchaser acknowledges that he,
she or it, or his, her or its investment advisor has received the following
documents from the Company:

                  (a) The Company's Form 10-K/A for fiscal year ended December
         31, 1999;

                  (b) The Company's Form 10-Q's covering three, six and nine
         month periods ending on March 31, June 30 and September 30 of 2000;

                  (c) Six press releases issued by the Company dated February
         16, 2000, March 30, 2000, May 16, 2000, August 21, 2000, October 11,
         2000 and October 16, 2000.

each Purchaser agrees to purchase from the Company, at the Closing, the number

                  (a) Prepare and file with the Commission the Registration
         Statement and use its best efforts to cause such Registration Statement

         no event later than 120 days after the Closing Date, and keep the
         Registration Statement effective pursuant to Rule 415 at all times,
         subject to Section 7.4, until such date as is the earlier of (i) the
         date on which all Registrable Securities have been sold by each Holder,
         and (ii) the date on which the Registration Rights terminate as set
         forth in Section 7.8;

                  (b) Promptly furnish to the Purchasers participating in such
         registration and to the underwriters (if any) of the securities being
         registered such reasonable number of copies of the registration
         statement, preliminary prospectus (and all required amendments and
         supplements to any thereof), final prospectus and such other documents
         as such Purchasers or such underwriters may reasonably request in order
         to facilitate the public offering of such securities proposed by the
         Purchaser;

                  (c) Cause such audited financial statements, legal opinions

         facilitate such registration; and

                  (d) Take all such further action as any Purchaser shall

         7.4 Suspension of Registration. The Company shall promptly notify the
Purchasers of (i) the issuance by the Commission of a stop order suspending the
effectiveness of the Registration Statement, (ii) the happening of any event, of
which the Company has knowledge, as a result of which the prospectus included in
the Registration Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a

<PAGE>   10

material fact required to be stated therein or necessary to make the statements
therein not misleading, and (iii) the occurrence or existence of any pending
corporate development that, in the reasonable discretion of the Company, makes
it appropriate to suspend the availability of the Registration Statement to
comply with Commission rules. In each case the Company shall use commercially
reasonable efforts to promptly prepare a supplement or amendment to the
Registration Statement to correct such untrue statement or omission, and deliver
such number of copies of such supplement or amendment to each Holder as such
Holder may reasonably request; provided that, the Company may delay to the
extent permitted by law the disclosure of material non-public information
concerning the Company the disclosure of which at the time is not, in the good
faith opinion of the Company, in the best interests of the Company (an "Allowed
Delay"); provided, further, that an Allowed Delay shall not exceed 30
consecutive days in any 365-day period, and there shall be no more than two such
Allowed Delay periods. The Company shall promptly notify the Purchasers in
writing of the existence of an Allowed Delay and shall advise the Purchasers in
writing to cease all sales under the Registration Statement until the end of the
Allowed Delay.

         7.5 Indemnification.

                  (a) The Company will indemnify and hold harmless each Holder
         and Zesiger Capital Group LLC ("ZCU"), each of their respective
         officers and directors, trustees, members, employees and partners, and
         each Person controlling such Holder within the meaning of Section 15 of
         the Securities Act, with respect to which registration has been
         effected pursuant to this Section 7 and each underwriter, if any, and
         each Person who controls any underwriter within the meaning of Section
         15 of the Securities Act, against all expenses, claims, losses, damages
         or liabilities (or actions in respect thereof), including any of the
         foregoing incurred in settlement of any litigation, commenced or
         threatened, arising out of or based on any untrue statement (or alleged
         untrue statement) of a material fact contained in any registration
         statement, prospectus, offering circular or other document, or any
         amendment or supplement thereto, incident to any such registration,
         qualification or compliance, or based on any omission (or alleged
         omission) to state therein a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances in which they were made, not misleading, or any violation
         by the Company of the Securities Act, the Exchange Act, state
         securities law or any rule or regulation promulgated under such laws
         applicable to the Company in connection with any such registration, and
         within a reasonable period the Company will reimburse each such Holder
         and ZCG, each of their respective officers and directors, trustees,
         members, employees and partners, and each Person controlling such
         Holder within the meaning of Section 15 of the Securities Act, each
         such underwriter and each Person who controls any such underwriter, for
         any legal and any other expenses reasonably incurred in connection with
         investigating, preparing, defending or paying any such claim, loss,
         damage, liability or action; provided that the Company will not be
         liable in any such case to the extent that any such claim, loss,
         damage, liability or expense arises out of or is based on any untrue
         statement or omission or alleged untrue statement or omission, made in
         reliance upon and in conformity with written information furnished to
         the Company by an instrument duly executed by such Holder, controlling

                  (b) Each Holder will, if Registrable Securities held by such

         Company, each of its directors and

         officers, each underwriter, if any, of the Company's securities covered
         by the Registration Statement, each Person who controls the Company or
         such underwriter within the meaning of Section 15 of the Securities
         Act, ZCG and each other such Holder each of their respective officers
         and directors, trustees, members, employees and partners, and each
         Person controlling such Holder within the meaning of Section 15 of the
         Securities Act, against all claims, losses, damages and liabilities (or
         actions in respect thereof) arising out of or based on any untrue
         statement (or alleged untrue statement) of a material fact contained in
         the Registration Statement, prospectus, offering, circular or other
         document, or any omission (or alleged omission) to state therein a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, and within a reasonable period will
         reimburse the Company, ZCG, such Purchasers, each of their respective
         officers and directors, trustees, members, employees and partners, and
         each Person controlling such Holder within the meaning of Section 15 of
         the Securities Act, for any legal or any other expenses reasonably
         incurred in connection with investigating or defending any such claim,
         loss, damage, liability or action, in each case to the extent, but only
         to the extent, that such untrue statement (or alleged untrue statement)
         or omission (or alleged omission) is made in the Registration
         Statement, prospectus, offering circular or other document in reliance
         upon and in conformity with written information furnished to the
         Company by an instrument duly executed by such Holder and stated to be
         specifically for use therein. Notwithstanding the foregoing, the
         liability of each Holder under this subsection (b) shall be limited in
         an amount equal to the gross proceeds before expenses and commissions
         to such Holder received for the shares sold by such Holder, unless such
         liability arises out of or is based on willful misconduct by such
         Holder.

                  (c) Each party entitled to indemnification under this Section
         7.5 (the "Indemnified Party") shall give notice to the party required
         to provide indemnification (the "Indemnifying Party") promptly after
         such Indemnified Party has actual knowledge of any claim as to which
         indemnity may be sought, and shall permit the Indemnifying Party to
         assume the defense of any such claim or any litigation resulting
         therefrom, provided that counsel for the Indemnifying Party, who shall
         conduct the defense of any such claim or any litigation, shall be
         approved by the Indemnified Party (whose approval shall not
         unreasonably be withheld or delayed), and the Indemnified Party may
         participate in such defense at such Indemnified Party's expense, and
         provided further that the failure of any Indemnified Party to give
         notice as provided herein shall not relieve the Indemnifying Party of
         its obligations under this Section 7 unless the failure to give such
         notice is materially prejudicial to an Indemnifying Party's ability to
         defend such action and provided further, that the Indemnifying Party
         shall not assume the defense for matters as to which there is a
         conflict of interest or separate and different defenses. No
         Indemnifying Party, in the defense of any such claim or litigation,
         shall, except with the consent of each Indemnified Party, consent to
         entry of any judgment or enter into any settlement which does not
         include as an unconditional term thereof the giving by the claimant or
         plaintiff to such Indemnified Party of a release from all liability in
         respect to such claim or litigation.

         7.6 Information by Holder. The Holder or Purchasers of Registrable
Securities included in the registration shall furnish to the Company such
information regarding such Holder or Purchasers, the Registrable Securities held
by them and the distribution proposed by such Holder or Purchasers as the
Company may request in writing and as shall be required in connection with the
registration referred to in this Section 7.

         most recent annual or quarterly report of the Company, and such other
         reports and documents of the Company and other information in the
         possession of or reasonably obtainable by the Company as the Holder may
         reasonably request in availing itself of any rule or regulation of the
         Commission allowing the Holder to sell any such securities without
         registration.
