                             EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (hereinafter "this Agreement") is made as of the
19th day of April, 2000 by and between USS HOLDINGS, INC., a Delaware
corporation (hereinafter "the Company"), and Roy D. Reeves, an individual
residing at 304 Lake Circle Drive, Greenville, South Carolina 29602,
(hereinafter "the Executive").

     WHEREAS, the Executive entered into a certain three-year employment
agreement with Better Mineral & Aggregates Company ("Better Mineral"), a wholly
owned subsidiary of the Company, dated as of even date herewith (the "Subsidiary
Employment Agreement") in which the parties agreed to certain terms of
employment;

     WHEREAS, pursuant to the Subsidiary Employment Agreement, the Company
desires to employ the Executive as the President and Chief Operating Officer of
Stone Materials Company, L.L.C. ("Stone Materials"), a wholly owned subsidiary
of Better Mineral and the Executive desires to be so employed by the Company, on
the terms and conditions set forth in the Subsidiary Employment Agreement and
herein;

     NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements set forth in the Subsidiary Employment Agreement and
herein, the Company and the Executive hereby agree as follows:

     1.  Employment.  The Company hereby agrees to have Stone Materials employ
         ----------
the Executive, and the Executive hereby agrees to serve, as President and Chief
Operating Officer of Stone Materials. The Executive agrees to perform such
duties and services as set forth in the Subsidiary Employment Agreement. The
Executive further agrees to perform such duties and services under such term of
employment as defined in the Subsidiary Employment Agreement.

     2.  Sales Bonus.  In addition to the salary, bonuses and other benefits set
         -----------
forth in the Subsidiary Employment Agreement, the Executive shall be entitled to
the following:

         (a) If during the Term of Employment as that term is defined in the
Subsidiary Employment Agreement, an IRR Event occurs as that term is defined in
the Stockholders Agreement, the Executive, in recognition for his services,
shall receive an amount equal to eight million dollars ($8,000,000.00), provided
that the IRR Event recognizes an appreciation in the value of USS Holdings'
Class A Common Stock such that the price at which USS Holdings' Class A Common
Stock will be acquired will be at or in excess of one hundred (100) percent
above the following target stock price in the year in which the IRR Event
occurs:

                           Year           Price per Share
                           ----           ----- --- -----
                            2000              $84.77
                            2001              $109.91
                            2002              $132.22
                            2003              $152.83
                            2004              $171.66
                            2005              $191.72
<PAGE>

If the IRR Event prices USS Holdings' Class A Stock at less than one hundred
(100) percent above, but in excess of the above target stock price in the year
in which the IRR Event occurs, the Executive shall receive an amount equal to
the product of (i) the percent by which USS Holdings' Class A Common Stock price
exceeds the above target stock price in the year in which the IRR Event occurs;
and (ii) eight million dollars ($8,000,000.00).

          (b) The target stock price referred to in paragraph (a) above shall be
adjusted if, at any time, the number of shares of Class A Common Stock
outstanding is increased by a stock dividend payable in shares of Class A Common
Stock or by a sub-division or split-up of shares of Class A Common Stock in a
manner as determined in good faith by the Board of Directors of the Company so
as to put the Executive in the same economic position as he was prior to such
event.  The target stock price referred to in paragraph (a) above should also be
adjusted if, at any time, the Company engages in any capital reorganization, or
any reclassification of the capital stock of the Company (other than a change in
par value or from par value to no par value or from no par value to par value or
as a result of a stock dividend or sub-division, split-up or combination of
shares) or the consolidation or merger of the Company with or into another
person (other than a consolidation or merger in which the Company is the
continuing corporation and which does not result in any change in the Class A
Common Stock) or of the sale or other disposition of all or substantially all of
the properties and assets of the Company as an entirety to any other person in a
manner as determined in good faith by the Board of Directors of the Company so
as to put the Executive in the same economic position as he was prior to the
transaction.  The provisions of this paragraph (b) shall similarly apply to
successive reorganizations, reclassifications, consolidations, mergers, sales or
other dispositions.

          (c) With respect to the payment described in Paragraph 2(a), in the
event such payment, either alone or in combination with any other payments the
Executive may receive under this Agreement, triggers liability under Section
280G and Section 4999 of the Internal Revenue Code of 1986, as amended, (the
"Code"), the Company and the Executive agree to use their best efforts to take
such actions as may be necessary to cause the stockholders of the Company to
approve such payment in a manner complying with Code Section 280G(g)(5)(B),
including without limitation providing information to the stockholders as
required by Code Section 280G(b)(5)(B)(ii).  In the event that the Company and
the Executive are unable to obtain such stockholder approval, the Company and
the Executive agree to use their best efforts to maximize the Company's ability
to deduct such payment under Code Section 280G and to minimize the Executive's
tax liability under Code Section 4999, except in no event shall the Executive be
required to accept any payment that would be less than the payment the Executive
would receive if full payment was made under Paragraph 2(a) of this Agreement
and the Executive paid any excise tax due under Code Section 4999 on such
payment.  Moreover, the Company and the Executive agree to utilize the procedure
set forth in Exhibit A to this Agreement.

     3.   Termination Following Change of Control.  If the Company terminates,
          ---------------------------------------
or causes Better Minerals to terminate, the Executive's employment following a
Change in Control as that term is defined in Paragraph 4(f) of the Subsidiary
Employment Agreement, the Company shall pay, or cause Better Minerals to pay,
the Executive any payments due him under Paragraph 2(a) of this Agreement.
Other than as specifically set forth in this Paragraph and under Paragraph 5(f)
of the Subsidiary Employment Agreement, neither the Company nor Better Minerals
shall

                                       2
<PAGE>

have any further obligation to Employee in the event of the Executive's
termination following a Change in Control.

     4.   Disputes.  In the event of any dispute between the parties hereto
          --------
arising out of or relating to this Agreement or the employment relationship,
including, without limitation, any claims of discrimination, between the Company
and the Executive, such dispute shall be settled by arbitration in Washington,
D.C. in accordance with the National Rules for the Resolution of Employment
Disputes then in effect of the American Arbitration Association.  Judgment upon
the award rendered may be entered in any court having jurisdiction thereof.

assume the terms and conditions of this Agreement.

                                   EXHIBIT A
                                   ---------

Limitation on Payment
---------------------
          Notwithstanding any other provision of this Agreement, if following an
IRR Event, any portion of the payment set forth in Paragraph 2(a), any severance
benefits or any other payment under this Agreement, or under any other agreement
with or plan of the Company (in the aggregate "Total Payments") would constitute
an "excess parachute payment," then the payments to be made to the Executive
under this Agreement may, if approved by the Executive, be reduced such that the
value of the aggregate Total Payments that the Executive is entitled to receive
shall be one dollar ($1) less than the maximum amount which the Executive may
receive without becoming subject to the tax imposed by Section 4999 of the
Internal Revenue Code of 1986 (the "Code"), or which the Company may pay without
loss of deduction under Section 280G(a) of the Code.

          However, the payments to be made to the Executive under this Agreement
shall be reduced if and only if so reducing the payments results in the
Executive receiving a greater net benefit than he would have received had a
reduction not occurred and an excise tax been paid pursuant to Code Section
4999.

          For purposes of this Agreement, the terms "excess parachute payment"
and "parachute payments" shall have the meanings assigned to them in Section
280G of the Code, and such "parachute payments" shall be valued as provided
therein.

Procedure for Establishing Limitation on Payments in Connection with an IRR
---------------------------------------------------------------------------
Event
-----

          Within sixty (60) days following an IRR Event and delivery of notice
by the Company to the Executive of its belief that there is a payment or benefit
due to the Executive which will result in an "excess parachute payment" as
defined in Section 280G of the Code, the Executive and the Company, at the
Company's expense, shall obtain the opinion of such legal counsel, which need
not be unqualified, as the Executive may choose, which sets forth: (i) the
<PAGE>

amount of the Executive's "annualized includible compensation for the base
period" (as defined in Code Section 280G(d)(1); (ii) the present value of the
Total Payments; and (iii) the amount and present value of any "excess parachute
payment." The opinion of such legal counsel shall be supported by the opinion of
a certified public accounting firm and, if necessary, a firm of recognized
executive compensation consultants. Such opinion shall be binding upon the
Company and the Executive.

          In the event that such opinion determines that there would be an
"excess parachute payment," the severance benefits hereunder or any other
payment determined by such counsel to be includible in Total Payments may, if
approved by Executive, be reduced or eliminated as specified by the Executive in
writing delivered to the Company within thirty (30) days of his receipt of such
opinion.

          The calculations, notices, and opinion provided for herein shall be
based upon the conclusive presumption that (i) the compensation and benefits
provided for herein; and (ii) any other compensation earned prior to the
effective date of termination by the Executive pursuant to the Company's
compensation programs (if such payments would have been made in the future in
any event, even though the timing of such payment is triggered by the Change in
Control), are reasonable.

          The Company shall pay any costs associated with obtaining the above
opinion.

                                                                   EXHIBIT 10.15

             EMPLOYMENT, CONSULTING AND NON-COMPETITION AGREEMENT
             ----------------------------------------------------

     THIS EMPLOYMENT, CONSULTING AND NON-COMPETITION AGREEMENT ("Employment,
Consulting and Non-Competition Agreement") is made as of the 31st day of
December 2000, by and between Richard E. Goodell ("REG") and U.S. Silica Company
("US Silica") and its direct and indirect parent companies USS Holdings, Inc.
("USSH"), BMAC Holdings, Inc. ("BMACH") and Better Minerals and Aggregates
Company ("BMAC" and together with US Silica, USSH and BMACH, herein sometimes
referred to as the "USS Group").

     WHEREAS, REG has served the USS Group for a number of years as its
President and in this service has developed a detailed knowledge of the USS
Group and its operations;

     WHEREAS, REG and the USS Group desire to agree to an arrangement pursuant
to which REG will continue to provide employment services to the USS Group for a
period of time;

     WHEREAS, REG and the USS Group desire to agree to an arrangement pursuant
to which REG would provide consulting services to the Company beginning at that
time that REG ceases to serve as an employee of the USS Group;

     NOW, THEREFORE, in consideration of the representations, covenants and
agreements hereinafter set forth, the sufficiency and adequacy of the
consideration being acknowledged by the parties hereto, REG and the USS Group
covenant and agree as follows:

     Section 1.  Employment Services.  (a)  REG will work as an employee of the
                 -------------------
USS Group at the direction of the Board of Directors of the USS Group and will
serve as a Director and Vice Chairman of USSH, BMACH and BMAC.  REG will work at
a time commitment level equal to 50% of a full-time employee and will receive a
salary equal to $212,500.00 and will continue to be eligible for all employee
benefit plans and programs available to other officers of the USS Group, and REG
shall be eligible for any bonuses for which other officers of the USS Group are
eligible, subject to the terms of the bonus programs, at the current rate (55%)
of salary. REG will be available to provide services to other companies with
which the USS Group contracts to provide such services.

          (b) REG's term of employment shall run until July 7, 2004. No further
commitment for employment for any specified duration (e.g. `lifetime',
`permanent' or `so long as performance is satisfactory') shall be binding on the
USS Group or any of its affiliates unless it is expressly set forth in a written
document and signed by REG and a duly authorized representative of the USS
Group.  Any attempt to orally modify any of the terms of this letter will have
no effect.  For the avoidance of doubt, the provisions set forth in Sections
1(c) and 1(d) shall have no applicability for periods prior to a Change of
Control (as hereinafter defined).

          (c) Upon a Change of Control of the USS Group (which is defined as a
sale of assets or the sale of the stock (including via a merger transaction) of
US Silica, USSH, BMACH or BMAC or the termination of the right of D. George
Harris and Anthony J. Petrocelli to name directors of USSH as provided in
Section 2(a) of the USSH Stockholders Agreement as in effect
<PAGE>

on the date hereof) (together, a "Change of Control"), REG shall be entitled to
terminate his employment and to receive as severance, in lieu of any severance
that might otherwise be payable by the USS Group, a severance payment equal to
the salary payable hereunder pursuant to Section 1(a) hereof through July 7,
2004. In lieu thereof, REG shall be entitled to continue his employment under
this letter agreement and to receive a bonus payment at the time of the change
of control equal to one year's salary and to receive a stay bonus equal to one
year's salary payable upon and conditioned upon continued employment until a
period of six months after the Change of Control.

          (d) Any termination of employment that occurs after a Change of
Control for any reason (including cause or any event which renders you unable to
perform the services contemplated hereunder) shall, for purposes of eligibility
for and calculation of benefits under employee benefit plans and programs, be
deemed to occur on the later of July 7, 2004 or the actual date of such
termination.  This deemed employment to July 7, 2004, is specifically intended
by the parties to provide that if REG terminates employment for any reason after
a Change in Control, then as of such termination REG shall be immediately
eligible to participate in the employer's retiree medical program.

     Section 2.  Consulting Services.  (a)  Following the termination of his
                 -------------------
employment with the USS Group ("Employment Termination") and until a date ten
years from the date of Employment Termination (the "Consulting Period"), REG
hereby agrees to make himself available for 30 days per calendar year (pro rated
for any partial year) to provide professional consulting services ("Consulting
Services") to the USS Group on such matters as the USS Group may reasonably
request his services.

          (b) Subject to Section 2(d) (ii) below, during the Consulting Period,
REG hereby agrees to make himself available for up to a further 30 days per
calendar year (pro rated for any partial year) for Consulting Services, as
requested by the Company.

          (c) The Company will provide REG with reasonable notice of the times
and dates for which Consulting Services are required hereunder; such times and
dates are subject to the mutual agreement of the parties.

          (d)  During the Consulting Period:

               (i) The USS Group hereby agrees to pay to REG the amount of
     $50,000 annually, payable monthly in arrears for the Consulting Services
     set forth in Section 2 (a) hereof.

               (ii) The USS Group hereby agrees to pay to REG the amount of
     $1,000 per day for any Consulting Services provided pursuant to Section
     2(b) hereof.

                                       2
<PAGE>

     Section 3.  Termination.  (a)  Unless terminated in accordance with the
                 -----------
following provisions of this Section 3 (a), the Company shall continue to retain
REG pursuant to this Employment, Consulting and Non-Competition Agreement and
REG shall continue to perform the services set forth herein.

             (i)  This Employment, Consulting and Non-Competition Agreement
     shall terminate automatically at the end of the month of REG's death.  In
     the event of REG's death, payments to REG or his personal representative
     may cease with the monthly payment following his death.

             (ii) The USS Group may terminate the obligations set forth in
     Section 2 of this Employment, Consulting and Non-Competition Agreement at
     any time for cause; cause shall mean (A) a material breach by REG of his
     obligations under this Employment, Consulting and Non-Competition Agreement
     or (B) misconduct, unethical conduct, dishonesty or other act materially
     adverse to the good will of the USS Group. The USS Group shall give REG
     written notice of termination for cause by certified mail, return receipt
     to his then office or residence address and the obligations set forth in
     Section 2 of this Employment, Consulting and Non-Competition Agreement
     shall terminate at the end of the month in which the notice was mailed.  In
     the event the USS Group terminates the obligations set forth in Section 2
     of this Employment, Consulting and Non-Competition Agreement for cause,
     payments to REG may cease with the one made in the month following
     termination. Notwithstanding any such termination, the other provisions of
     this Employment, Consulting and Non-Competition Agreement shall continue.

          (b) In the event of REG's disability, which disability prevents him
from performing the employment services or consulting services designated
hereunder, payment to REG hereunder shall continue until two years from the date
of disability.  For purposes of this Employment, Consulting and Non-Competition
Agreement, REG shall be considered to have a disability only if (i) his mental
facilities or his ability to communicate are disabled in a manner rendering him
incapable of performing the services hereunder, or (ii) he is unable to travel
for at least ninety (90) consecutive days, for any reason, more than 50 miles
from Berkeley Springs, WV.

     Section 4.  Non-Competition.  REG agrees that neither he nor any entity
                 ---------------
within his control (an "Affiliate") shall from the date hereof until a date ten
years from the date of Employment Termination (the "Restrictive Period"),
engage, either directly or indirectly, as a principal or for his own account or
solely or jointly with others, or as stockholders in any corporation or joint
stock association, in any business that competes with the business of the USS
Group anywhere in the world as its business exists as of the date of Employment
Termination (the "Restricted Activities"); provided that nothing here shall
prohibit the ownership of not more than five (5%) percent of any class of shares
of stock or securities of any corporation that competes with the business of the
USS Group and that has a class of publicly traded securities.

     Section 5.  Employees of the Company.  During the Restrictive Period, REG
                 ------------------------
shall not, nor shall he permit any of his Affiliates, individually or jointly
with any other person, to, directly or indirectly solicit the employment of any
person who was an employee of the USS

                                       3
<PAGE>

Group, its subsidiaries or affiliates, at any time during the period of twelve
months immediately preceding such employment or retention.

     During the Restrictive Period, REG shall promptly furnish in writing to the
USS Group, its subsidiaries or affiliates, any information reasonably requested
by the USS Group (including any third party confirmations) with respect to any
activity or interest REG may have or conduct in any business then competing with
the business of the USS Group, provided, however, nothing shall require REG to
violate any statute, order, rule, regulation, agreement or obligation
restricting such disclosure.

     Section 6.  Hunting Leases.  The USS Group hereby acknowledges that it has
                 --------------
entered into leases as of December 31, 2000 relating to (i) the Tonoloway Ridge
Tract, which is attached as Exhibit "A", and (ii) the Hammond Tract, which is
attached as Exhibit "A-1".  For the avoidance of doubt, a termination of one or
both of such leases by REG shall not affect the obligations hereunder, and a
termination of this Employment, Consulting and Non-Competition Agreement by the
USS Group shall not affect the Hunting Leases.

     Section 7. Reporting; Services; Expenses.  (a)  During the term of the
                -----------------------------
Employment, Consulting and Non-Competition Agreement, REG shall report to the
Board of Directors of the USS Group.

             (b) The USS Group shall provide REG with office services and

          (d) Should the USS Group materially breach its obligations under this
Employment, Consulting and Non-Competition Agreement, REG's obligations under
Sections 4 and 5 hereof shall be voidable by REG, provided REG acts within 60

                               AGREEMENT OF LEASE
                               ------------------

     THIS AGREEMENT OF LEASE is made this 1st day of January 2001, by and
between U. S. SILICA COMPANY ("LESSOR"), and RICHARD E. GOODELL ("LESSEE").

        1.   DEMISED PREMISES. LESSOR agrees to lease, in and for consideration
and upon such terms as are hereinafter stated, that certain property containing
approximately 483 acres, located in Washington County, Maryland, located on the
north side of the Potomac River, constituting a portion of the "Tonoloway Ridge
Tract", being improved with a hunting cabin (f/k/a the "Shelby House"), and
being shown on the attached map (the Demised Premises being outlined in yellow).

        2.   TERM. This Lease shall commence effective January 1, 2001
("Commencement Date"), and shall continue thereafter for a term of nineteen (19)
years, terminating automatically (and without requirement of notice) as of 12:00
A.M., on the date which is nineteen (19) years after the Commencement Date.

        3.   RENT. LESSEE covenants and agrees to pay to LESSOR rent in the
amount of $1.00 per year, payable on November 1 of each year of the Lease term.
LESSEE shall further reimburse LESSOR for County property taxes on a pro-rated
basis equal to the per cent of the total Tonoloway Ridge Tract represented by
the Demised Premises, within thirty days of submission by LESSOR to LESSEE of
the tax statement and calculation of pro-rated share. LESSEE shall further be
solely responsible for any and all utilities service to the cabin on the Demised
Premises.

        4.   USE. The Demised Premises shall be used by the LESSEE and his
family, friends, guests and invitees for hunting, fishing and other recreational
purposes. LESSEE may utilize the cabin and any appurtenant outbuildings for
occasional residential purposes, but the same may not be occupied as a primary
residence. No commercial activity of any nature may be conducted on or about the
Demised Premises. No fees may be charged by the LESSEE to any person or entity
related to the use of the Demised Premises. No timber or mining rights
(including silica sand and/or rock, oil, gas or coal) are granted to the LESSEE
by virtue of this Lease, all such rights being expressly reserved unto the
LESSOR.

        5.   ALTERATIONS; WASTE. The LESSEE may improve and make alterations to
the existing cabin and any outbuildings on the Demised Premises, at the LESSEE's
sole cost and without need of prior approval by the LESSOR. Any such alterations
shall be done in a professional and workmanlike manner, and shall become the
property of the LESSOR upon termination of this Lease, without compensation or
reimbursement being owed to the LESSEE for the value of such improvements or the
time expended thereon. The LESSEE shall not commit waste to the Demised
Premises; however, nothing herein shall be deemed to prohibit the LESSEE from
the razing and removal of such cabin and outbuildings if he so chooses.

        6.   PRIOR AGREEMENT. The LESSEE acknowledges that this Lease is subject
to the terms and conditions of that prior Agreement dated April 13, 1998 between
the LESSOR and the Tonoloway Rod and Gun Club, Inc., affecting a portion of the
Demised Premises.
<PAGE>

          7.   EXCLUSIVITY OF LEASE RIGHTS. The LESSOR shall not grant any other
leases or licenses for hunting or other recreational purpose to all or any
portion of the Demised Premises so long as this Lease is in full force and
effect. The LESSOR further agrees that it will not expand or enlarge in any
manner (including, but not limited to, permitted activities, extent of property
involved, or duration of activities) the lease/license rights granted under the
above-referenced prior Agreement with the Tonoloway Rod and Gun Club, Inc. in
the event that such Agreement is hereafter renewed or renegotiated.

          8.   SUBLEASE; ASSIGNMENT. The LESSEE shall not sublease the Demised
Premises or any portion thereof. The LESSEE shall not assign this Lease nor any
benefit or obligation hereof.

          9.   INDEMNIFICATION. The LESSEE does hereby indemnify, release and
hold harmless the LESSOR and its successors and assigns from any and all claims
and liability of every kind and nature, including, but not limited to, personal
injury (including loss of life) and property damage, arising out of the use of
the Demised Premises by the persons entitled thereto under this Lease. The
LESSEE shall at his sole cost maintain a personal liability umbrella insurance
policy in a face amount of not less than $1,000,000.00 throughout the term of
this Lease.

          10.  COMPLIANCE WITH LAWS. The LESSOR and his family, friends, guests
and invitees shall at all times when utilizing the Demised Premises for
recreational purposes (especially hunting) strictly comply with all Federal,
State and local laws and regulations applicable to such activities.

          11.  TERMINATION. This Lease shall automatically terminate as of
12:00 A.M., on the date nineteen (19) years after the Commencement Date. This
Lease may be terminated prior to said date by occurrence of any of the following
events:

          A.   The failure of The LESSEE to promptly and fully comply with any
term or provision of this Lease shall constitute a material breach and shall
give the LESSOR in its sole discretion the right to elect to terminate the
Lease. The failure by the LESSOR to so elect to terminate shall not be deemed to
constitute a waiver or estoppel of the LESSOR's right in the future to so
terminate.

          B.   The election by the LESSOR to mine the Demised Premises or any
portion thereof, it being understood by the parties hereto that the term "mine"
for purposes of this Lease means the extraction in commercial quantities of
silica sand ore.

          C.   The sale by the LESSOR of all or any portion of the Demised
Premises. However, the term "sale of all or any portion of the Demised
Premises", as used in this paragraph 11 and hereafter in paragraph 12, shall not
include a sale as part of a sale of all (or substantially all) of the assets of
the LESSOR (i.e., a Sale of Business), or of all (or substantially all) of the
LESSOR's Berkeley Springs facility.

     Should the LESSOR elect to terminate the Lease for the reasons set forth
above, the LESSOR shall serve notice of termination upon the LESSEE by mailing
same, certified mail

                                       2
<PAGE>

postage prepaid, to the LESSEE to his address shown below his signature hereon,
one (1) year prior to the effective date of termination. Such notice shall be
effective upon the mailing thereof.

          D.  The election by the LESSEE to terminate, notice of which shall
be mailed, certified mail postage prepaid, to the LESSOR at its address shown
below, one year prior to the effective date of termination. Such notice shall be
effective upon the mailing thereof.

          E.  The death of the LESSEE.

     Upon termination of this Lease, regardless of method or reason thereof, all
personal property of the LESSEE shall be promptly (within thirty days of
termination date) removed from the Demised Premises; any personalty of the
LESSEE not so removed shall be deemed to constitute abandoned property and shall
be disposed of accordingly by the LESSOR.

          12. RIGHT OF FIRST REFUSAL. In the event that the LESSOR during the
term of this Lease contracts with a third party for the sale of all or any
portion of the Demised Premises, or for properties which may include all or any
portion of the Demised Premises, the LESSOR shall give notice to the LESSEE of
such intent to sell. Such notice shall be sent by certified mail, postage
prepaid, and shall be effective upon the mailing thereof. The LESSEE shall have
thirty days from the date of said notice in which to notify the LESSOR of the
LESSEE's intent to exercise the right of first refusal granted herein; such
notice shall be by certified mail, postage prepaid, and shall be effective upon
the mailing thereof. The LESSEE shall then have ninety days from the date of the
LESSOR'S notice of intent to sell in which to consummate the purchase of the
Demised Premises from the LESSOR at a price (and upon such terms) equal to that
offered by the third party whose contract was disclosed to the LESSEE by the
LESSOR. In the event that the proposed sale by the LESSOR to a third party is
for only a portion of the Demised Premises, the LESSEE may exercise his right to
purchase only as to that portion, or may elect to purchase all of the Demised
Premises, in which case the purchase price shall be equal to Fair Market Value
(as determined by a licensed and independent appraiser, whose fee shall be paid
by the LESSEE), but shall in no event be less than the third party's offer
calculated on a per-acre basis. In the further event that the LESSEE notifies
the LESSOR that he does not intend to exercise his right of first refusal, or
makes no response to the LESSOR'S notice of intent to sell within the prescribed
time limit, the LESSOR may proceed with notice of termination of this Lease as
provided in the preceding paragraph 11. The right of first refusal granted
herein shall only apply to the Demised Premises, and shall not apply to any
other properties of the LESSOR. Furthermore, the term "sale of all or any
portion of the Demised Premises" shall not include, and the right of first
refusal granted herein shall not apply to, a sale as part of a sale of all (or
substantially all) of the assets of the Lessor (i.e., a Sale of Business), or of
all (or substantially all) of the LESSOR's Berkeley Springs facility, regardless
of whether the Demised Premises are included in such sale. In the event that
there is a reasonably material change in the price or terms of the third party's
offer of which the LESSOR gave notice to the LESSEE, the LESSOR shall be
required to provide notice (in the manner provided herein) to the LESSEE of such
change, and the time periods provided to the LESSEE herein for exercise and
consummation of his right of first refusal shall re-commence with the mailing of
such notice by the LESSOR.

              13.  RECORDING PROHIBITED. The LESSEE shall not record (nor cause
to be recorded) this Lease, nor any memorandum or notice thereof, in the
Washington County land records.

     Upon termination of this Lease, regardless of method or reason thereof, all
personal property of the LESSEE shall be promptly (within thirty days of
termination date) removed from the Demised Premises; any personalty of the
LESSEE not so removed shall be deemed to constitute abandoned property and shall
be disposed of accordingly by the LESSOR.

         12.  RIGHT OF FIRST REFUSAL. Other than as part of a Sale of Business,
in the event that the LESSOR during the term of this Lease contracts with a
third party for the sale of all or any portion of the Demised Premises, or for
properties which may include all or any portion of the Demised Premises, the
LESSOR shall give notice to the LESSEE of such intent to sell. Such notice shall
be sent by certified mail, postage prepaid, and shall be effective upon the
mailing thereof. The LESSEE shall have thirty days from the date of said notice
in which to notify the LESSOR of the LESSEE'S intent to exercise the right of
first refusal granted herein; such notice shall be by certified mail, postage
prepaid, and shall be effective upon the mailing thereof. The LESSEE shall then
have ninety days from the date of the LESSOR's notice of intent to sell in which
to consummate the purchase of the Demised Premises from the LESSOR at a price
(and upon such terms) equal to that offered by the third party whose contract
was disclosed to the LESSEE by the LESSOR. In the event that the proposed sale
by the LESSOR to a third party is for only a portion of the Demised Premises,
the LESSEE may exercise his right to purchase only as to that portion, or may
elect to purchase all of the Demised Premises, in which case the purchase price
shall be equal to Fair Market Value (as determined by a licensed and independent
appraiser, whose fee shall be paid by the LESSEE), but shall in no event be less
than the third party's offer calculated on a per-acre basis. In the further
event that the LESSEE notifies the LESSOR that he does not intend to exercise
his right of first refusal, or makes no response to the LESSOR's notice of
intent to sell within the prescribed time limit, the LESSOR may proceed with
notice of termination of this Lease as provided in the preceding paragraph 11.
The right of first refusal granted herein shall only apply to the Demised
Premises, and shall not apply to any other properties of the LESSOR.
Furthermore, the term "sale of all or any portion of the Demised Premises" shall
not include, and the right of first refusal granted herein shall not apply to, a
sale as part of a sale of all (or substantially all) of the assets of the LESSOR
(i.e., a Sale of Business), or of all (or substantially all) of the LESSOR's
Berkeley Springs facility, regardless of whether the Demised Premises are
included in such sale. In the event that there is a reasonably material change
in the price or terms of the third party's offer of which the LESSOR gave notice
to the LESSEE, the LESSOR shall be required to provide notice (in the manner
provided herein) to the LESSEE of such change, and the time periods provided to
the LESSEE herein for exercise and consummation of his right of first refusal
shall re-commence with the mailing of such notice by the LESSOR.

         13.  RECORDING PROHIBITED. The LESSEE shall not record (nor cause
to be recorded) this Lease, nor any memorandum or notice thereof, in the
Washington County land records.

LESSOR:                                  LESSEE:
