EXHIBIT 10.25
PURCHASE OPTION AGREEMENT
THIS PURCHASE OPTION AGREEMENT (this “Agreement”), executed and effective as of the 21st day of December, 2015 (the “Effective Date”) [Note:  This Agreement will not be effective until the Closing under the APA.], is between Performance Technologies, LLC, an Oklahoma limited liability company (“Company”), and Superior Silica Sands LLC, a limited liability company (“Supplier”).  Company and Supplier may be hereinafter referred to as the “Parties” or individually, as a “Party”.
WHEREAS, PTL Prop Solutions, L.L.C., an Oklahoma limited liability company (“PPS”) and Supplier entered into that certain Asset Purchase Agreement, dated as of September 17, 2015 (the “APA”), pursuant to which PPS agreed to sell to Supplier, and Supplier agreed to purchase from PPS, certain of PPS’s right, title and interest in, to and under certain real property rights, options and leases and other assets useful in the mining, development and production of frac sand in Jackson County, Wisconsin (the “Mine”); and 
WHEREAS, it is a condition to the consummation of the transactions contemplated by the APA that Company and Supplier enter into this Agreement, pursuant to which Company shall have an option to purchase the Material (as defined below) from Supplier.
NOW, THEREFORE, in consideration of the foregoing premises and other good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parties agree as follows:
		
	1.
	Option to Purchase Certain Products.

a.    Grant and Exercise of Purchase Option.
i.    Supplier hereby grants to Company an option, exercisable on a monthly basis (each a “Contract Volume Option”), to purchase sand and proppants satisfying the quality specifications set forth on Exhibit A (the “Material”) up to the specified volume (the “Contract Volume”) allocated by mesh size as set forth on Exhibit B (the “Contract Volume Schedule”), up to an aggregate total amount of *** tons of Material.  The first Contract Volume Option will be exercisable upon the earlier to occur of (1) the second anniversary of the Effective Date and (2) the date on which Company and Supplier mutually agree that Company is able to consume the Contract Volume hereunder and Supplier is able to provide the Contract Volume hereunder (the “Option Commencement Date”).
ii.    Notwithstanding anything in this Agreement to the contrary, Company shall have the right to exercise a Contract Volume Option for any month

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

on or after the Option Commencement Date regardless of whether the Mine has been fully developed, constructed and completed or it is otherwise operational, and Supplier shall be obligated to supply the Material requested in connection with the exercise of a Contract Volume Option by Company from Supplier’s, or any of its affiliate’s, other facilities which shall be (1) unit train capable, (2) originate on the Union Pacific Railroad, and (3) approved in advance by Company in writing if from an origin other than the Mine, subject to the terms and conditions of this Agreement.  In the event Supplier can produce the requested Contract Volume from the Mine, Supplier shall be entitled to supply the Material from the Mine without the necessity of obtaining Company’s approval.  For the avoidance of doubt, in the event that any volume of Material purchased by Company hereunder is supplied from a source other than the Mine, such volume shall count against the scheduled Contract Volume for that calendar month and qualify for the Discount.  In addition, the parties may mutually agree to swap Material produced from the Mine (that would otherwise be purchased by Company pursuant to its exercise of a Contract Volume Option in any calendar month) with Material produced from Supplier’s or any of its affiliate’s other facilities, in which case such Material will count against the scheduled Contract Volume for that calendar month and qualify for the Discount.
iii.    If Company desires to exercise its Contract Volume Option in any particular month, then Company will deliver to Supplier not less than thirty (30) days in advance of the desired delivery date for such month a purchase order in the form attached hereto as Exhibit C, setting forth the volume of Material to be purchased, the applicable Current Price and Discount (each as defined herein), (each, a “Purchase Order”), which Purchase Order shall constitute a commitment to purchase the volume of Material identified in such Purchase Order.  All Purchase Orders shall contain the required shipment date, Incoterms and point of delivery.
b.    Volume. 
i.If Company timely delivers a Purchase Order, the same shall be deemed accepted by Supplier as to the volume set forth therein, up to an aggregate volume of Material equal to the applicable prorated monthly Contract Volume plus the Below 80% Volume Reserve (as defined below) that Company is entitled to purchase as of such month plus the Deferred Contract Volume Reserve (as defined below) that Company is entitled to purchase as of such month, the aggregate of which shall not exceed 120% of the prorated monthly Contract Volume (the “Maximum Aggregate Contract Volume”).  If Company issues a Purchase Order for quantities of Material in excess of such Maximum Aggregate Contract Volume for a particular month, Supplier will notify Company within five (5) Business Days of receipt of 

2

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

the Purchase Order as to whether Supplier accepts or rejects the portion of the Purchase Order relating to such excess quantity for the applicable month; provided, that it is understood that the Discount (as defined below) shall not be applicable to the price of any Material acquired over one hundred percent (100%) of the Contract Volume in any given month.
i.    If Company elects to exercise a Contract Volume Option for any particular month for a volume of Material not less than eighty percent (80%) but less than one hundred percent (100%) of the scheduled Contract Volume, then the difference between one hundred percent (100%) of the scheduled Contract Volume for the applicable month and the actual volume of Material purchased by Company from Supplier for that month that is not below eighty percent (80%) of the Contract Volume will be deferred and accrued for future purchase by Company (the “Deferred Contract Volumes,” and the aggregate of such Deferred Contract Volumes that remain unpurchased by the Company as of any point in time, collectively the “Deferred Contract Volume Reserve”).
ii.    If Company elects to exercise a Contract Volume Option for any particular month for a volume of Material less than eighty percent (80%) of the scheduled Contract Volume, for any reason other than a Force Majeure Event (as defined in Section 3.n), then:
(1)    Subject to clauses (2) and (3) below, the difference between eighty percent (80%) of the scheduled Contract Volume for the applicable month and the actual volume of Material purchased by Company from Supplier for that month will be deferred and accrued for future purchase by Company (the “Below 80% Volumes,” and the aggregate of such Below 80% Volumes that remain unpurchased by the Company as of any point in time, collectively the “Below 80% Volume Reserve”).
(2)    The Below 80% Volumes from any particular month shall remain in the Below 80% Volume Reserve and available for purchase by the Company for the remainder of the calendar year in which such month occurs (the “Below 80% Occurrence Year”) and until the end of the following calendar year.
(3)    At the end of each calendar year Company will forfeit its Contract Volume Option to purchase Below 80% Volumes from the calendar year prior to such calendar year that remain unpurchased by Company and such forfeited volumes shall be removed from the Below 80% Volume Reserve but shall reduce Company’s option to purchase *** tons of Material 

3

on a ton for ton basis.  For the avoidance of doubt, the process contemplated by this clause (3) shall not begin until the end of the second calendar following the Commencement Option Date.
(4)    With respect to any Below 80% Volumes forfeited pursuant to clause (3) above (unless such Below 80% Volumes were initially deferred pursuant to clause (1) above in a month in which 50% or less of the frac fleet of Company and its affiliates were operating, in which case this clause (4) does not apply), Company shall pay to Supplier an amount equal to $*** per ton for 33% of such forfeited Below 80% Volumes.  Such payment shall be due from Company within thirty (30) days after the Material is forfeited.
(5)    Company’s discount for products purchased in such calendar month, if any, will be reduced by fifty percent (50%) of the then current Discount rate per ton purchased.
(6)    The Deferred Contract Volume for such month shall be 20% of the scheduled Contract Volume for such month, which amount shall be added to the Deferred Contract Volume Reserve.
iii.    If in any month, Company elects to exercise a Contract Volume Option for at least 80% of the scheduled Contract Volume for such month, then volume of Material purchased in excess of such 80% threshold shall be allocated first against the then current Below 80% Volume Reserve (on a first-in/first-out basis from the Below 80% Volume Reserve), which shall be reduced by the amount of such excess over the 80% threshold.  For the sake of clarity, the Discount shall apply to all such purchases, regardless of whether the volume is counted against the Below 80% Volume Reserve, the Deferred Contract Volume Reserve or otherwise except as specifically set forth in Section 1.b.iii(5) and the last sentence of Section 1.b.i.  Company will have the right to purchase volumes in excess of the scheduled Contract Volume for any given month by drawing against the accrued Below 80% Volume Reserve, if any, provided that in a given month Company will not have the right to draw more than the Maximum Aggregate Contract Volume and the Discount shall not be applicable to any tons purchased exceeding one hundred percent (100%) of the prorated Contract Volume as set for in Section 1.b.i for such month.
iv.    Supplier acknowledges and agrees that Company is relying on the Supplier to provide the scheduled Contract Volumes on a monthly basis.  In the event that Company timely delivers a Purchase Order up to the applicable Maximum Aggregate Contract Volume for any given month, and Supplier is unable to provide the volumes requested in Company’s Purchase Order for any reason other than a 

4

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

Force Majeure Event, then Company’s discount for Material purchased in that calendar month will be increased by fifty percent (50%) of the then current discount rate per ton purchased.  For the avoidance of doubt, any volume of Materials ordered by Company, but not delivered by Supplier, shall not be considered part of the Deferred Contract Volume Reserve or the Below 80% Volume Reserve, or counted against the *** tons of Material to which Company is entitled to purchase under this Agreement.
v.    The Parties will review the Contract Volume Schedule on a calendar year basis and make such revisions that are mutually agreed to by the Parties.  In the event that the Parties are unable to agree upon any revisions to the Contract Volume Schedule, then the Contract Volume Schedule in effect for the prior calendar year shall continue to be in effect for the subsequent calendar year.
c.    Pricing; Discount; Payment.
i.Company will pay to Supplier the per ton purchase price equal to the applicable Current Price (as defined in Section 1.c.ii) minus the then applicable Discount (as defined in Section 1.c.iv.)
ii.For purposes of this Agreement, “Current Price” shall mean the pricing set forth on Exhibit D.  No more often than quarterly, either Party may request an adjustment to the then Current Price to reflect the weighted average price (by mesh size and pickup point) purchased by Company and its affiliates for sand and proppants substantially similar to the Material purchased from all of their other suppliers during the previous quarter.  Such weighted average price shall not include any discounts provided to Company or its affiliates for any consideration provided to such Supplier by Company or one of its affiliates.  If within fifteen (15) days following any such request, the Parties have not agreed on such weighted average price, then the Parties shall submit their pricing dispute to an independent auditor selected by the Parties (the “Independent Auditor”).  If the parties cannot agree on the Independent Auditor, the Independent Auditor shall be a national accounting firm selected by Supplier; provided, that Supplier may not select an accounting firm then currently utilized by Company.  The Independent Auditor shall have the right to review all of Buyer’s, and its affiliates, books and records in connection with such determination and Buyer shall supply the same to the Independent Auditor so that the Independent Auditor can resolve the dispute as to such weighted average price within fifteen (15) days after engagement and such resolution shall be binding upon Company and Supplier.  The fees and expenses of the Independent Auditor shall be paid by the Party that requested the adjustment in Current Price.  Company and Supplier agree that any and all information, whether written or oral, provided to the 

5

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

Independent Auditor shall be confidential information not be disclosed by the Independent Auditor to the other Party or any third party or used by the Independent Auditor for any reason other resolving such dispute, which obligation shall be included in any engagement letter or similar arrangement among Company, Supplier and the Independent Auditor.  In the event the Independent Auditor does not agree to be bound by such restrictions, Company and Supplier shall select a different Independent Auditor.
iii.Unless this Agreement is properly assigned by either Party to a non-affiliate of such Party, any adjustment to the Current Price under this Agreement shall also apply to the “Current Price” charged by Supplier under that certain Amended and Restated Master Supply Agreement, dated as of even date herewith (the “Existing Supply Agreement”).
iv.For purposes of this Agreement, “Discount” means a discount applicable to all purchases of Material pursuant to this Agreement (except as may otherwise be set forth herein), which will be determined in accordance with Exhibit D.  The discount rate shall be determined based on the applicable Current Price for such Material.  The Discount will be applied to reduce the Current Price for all Material purchased pursuant to this Agreement.  For the sake of clarity, the Current Price used for purposes of determining the Discount shall be the then Current Price (by mesh size) FCA Supplier’s plants, regardless of whether Material is purchased from Supplier’s terminals or Supplier’s plants.
d.    Purchase and Sale.  If Company timely exercises its Contract Volume Option for any particular month, then the sale by Supplier, and purchase by Company, of the volume of Material set forth in the applicable Purchase Order shall be governed by the terms and conditions of this Agreement, including, without limitation, the Terms and Conditions attached hereto in Exhibit E.
e.    Rail Cars.  Company and Supplier agree to the following railcar sharing arrangement:
i.Commencing as of the Option Commencement Date, Company will provide, at no cost to Supplier, a number private railcars as periodically agreed to by the Parties for support of Company’s requirements for Purchase Orders issued hereunder having the terms FCA Railcar (the “Company Railcar Allocation”).  Company shall pay any and all fees necessary to introduce such rail cars into the rail system servicing deliveries to Company in support of this Agreement.  Company will not require that such railcars be used exclusively for Company’s purchases under this Agreement.  Supplier shall be solely liable for, and shall indemnify and hold 

6

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

harmless Company from and against any and all Losses incurred by Company in connection with Supplier’s negligent possession, use, maintenance or other operation of such Company Railcar Allocation, except to the extent that any such Losses arise out of any negligence or willful misconduct on the part of Company.
ii.Supplier shall at all times make available private railcars, at no cost to Company, consisting of Supplier’s private railcars (each a “Supplier Car”) or Company’s private railcars made available to Supplier, in a quantity equal to Company’s Railcar Allocation, necessary to satisfy any outstanding Company Purchase Order under this Agreement having the Incoterms FCA Railcar.
iii.In addition, Supplier agrees to provide, if available, such quantity of Supplier Cars in excess of the Company Railcar Allocation (each an “Additional Supplier Car”) in a timely manner, and as available, if necessary to adhere to the delivery date for the applicable Purchase Order.
iv.Supplier agrees to invoice for Additional Supplier Car usage only if the net volume of Railcar Days in Service (as defined below) exceeds the total volume of Company’s Railcar Service Days Available (as defined below) as follows:
(1)In the event the Company’s Railcar Service Days Available in any calendar month exceeds the Railcar Days in Service, the number of excess railcar days of availability (the “Company’s Excess Railcar Availability”) shall be carried over to the Company’s balance for use as a credit in future months when the Company’s Railcar Allocation is insufficient to satisfy the Railcar Days in Service.
(2)In the event the Railcar Days in Service in any calendar month exceeds the Company’s Railcar Service Days Available inclusive of the Company’s Excess Railcar Availability balance, if any, (collectively the “Shortfall in Company’s Railcar Availability”) Supplier shall invoice the Company on a monthly basis for the amount of the Shortfall in Company’s Railcar Availability at the rate of Supplier’s actual cost to own and operate such rail cars, including , without limitation, the cost to operate and any insurance thereon, but excluding the cost to introduce such cars into the system.
v.Company shall be liable for and shall defend, indemnify, and hold harmless Supplier from any demurrage charges and any freight or similar transportation charges at Company’s destinations, except to the extent that such 

7

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

charges are due to Supplier’s gross negligence or willful misconduct or other actions by Supplier that cause such charges to be incurred.
vi.Supplier shall be liable for and shall defend, indemnify, and hold harmless Company from any demurrage charges and any freight or similar transportation charges at Supplier’s origin(s) and destinations other than Company’s destinations, except to the extent that such charges are due to Company’s gross negligence or willful misconduct or other actions by Company that cause such charges to be incurred.
vii.For purposes of this Section 1.e, (y) “Company’s Railcar Service Days Available” means the then current Company’s Railcar Allocation multiplied by the total number of days in a calendar month (e.g., Company has a Railcar Allocation of 100 cars and the calendar month has 30 days, the Company’s Railcar Service Days Available would be 100 cars x 30 days or 3,000 railcar days in that calendar month) and (z) “Railcar Days in Service” shall mean the total number of days in a calendar month of all private railcars released from Supplier’s originating sand plant(s) in support of FCA railcar shipments to Company, regardless of if the railcar is an Additional Supplier Railcar or Company supplied railcar, until such time the railcars are returned to the originating sand plant.  Supplier shall present a rail tracking report supporting the calculation of the total Railcar Days in Service at the end of each calendar month.
viii.Additional terms and conditions for Company’s and Supplier’s use of such railcars shall be as attached hereto in Exhibit G (i.e., the Railcar Usage Agreement) and are incorporated herein by reference and shall be binding on the Parties, whether or not such Railcar Usage Agreement has been executed by any of the Parties.  To the extent of any inconsistency between the Railcar Usage Agreement and this Agreement, this Agreement shall control.

2.    TERMS AND CONDITIONS
These Terms and Conditions shall exclusively govern and control each of the parties’ respective rights and obligations with respect to the subject matter herein contained, including with respect to any sale by Supplier and purchase by Buyer of Items.  Without limiting the generality of the foregoing, any additional, contrary or different terms or conditions contained in any Purchase Order, order form, invoice or other request or communication by Supplier pertaining to the sale of Items, or any attempt to modify, supersede, supplement or otherwise alter these Terms and Conditions, shall not modify these Terms and Conditions or be binding on the parties.  Notwithstanding the foregoing, the contents of a Purchase Order shall be valid pertaining to the Items only as to model number or similar identifier, quantity, requested ship date, pricing and billing information.
3.    TERM OF AGREEMENT

20
*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

These Terms and Conditions shall be binding on the parties upon Supplier’s acceptance of the Purchase Order, either in writing or by commencement of performance in accordance with the Purchase Order.  These Terms and Conditions shall remain in effect unless and until Buyer provides no less than thirty (30) days’ prior written notice of termination to Supplier; provided, that, any such termination shall not affect the accrued rights and obligations of the parties nor shall it act to relieve either party with respect to incomplete or outstanding orders.
4.    PRICING AND PAYMENT
The price charged to Buyer for any Item shall be mutually agreed between Buyer and Supplier.  Unless otherwise agreed to in writing by an authorized officer of Buyer, payment terms shall be net thirty (30) days from the date of applicable invoice.  In the event Supplier does not submit to Buyer an applicable invoice within ninety (90) days of Buyer’s receipt of corresponding Items, then Supplier agrees and acknowledges that Buyer reserves the right to refuse payment with respect to such Items without penalty or recourse.
5.    TAXES
All taxes which Supplier intends to pass through for Buyer’s account, including, but not limited to, sales (including, without limitation, bulk sales), use, value added, transfer, documentary, stamp, excise and other similar taxes and fees, including, but not limited to, licensing, duties, customs, tariffs, imposts, and government imposed surcharges (collectively, “Taxes”), relating to the Items shall be invoiced and stated separately by Supplier.  Supplier shall remit all such Taxes to the appropriate taxing authority unless Buyer provides proof of tax exemption.  In the event Buyer is prohibited by law from making payments to Supplier unless Buyer first deducts or withholds such Taxes therefrom and remits such Taxes to the local taxing authority, then Buyer shall duly withhold such Taxes and shall pay to Supplier the remaining net amount.  Buyer shall not reimburse Supplier for any amount of such Taxes so withheld.  IN THE EVENT SUPPLIER DOES NOT INVOICE APPLICABLE TAXES RELATING TO THE ITEMS, AND IS SUBSEQUENTLY AUDITED BY ANY TAXING AUTHORITY, BUYER SHALL NOT BE RESPONSIBLE FOR PAYMENT OF ANY SUCH TAXES, AND SUPPLIER SHALL RELEASE, DEFEND, INDEMNIFY AND HOLD HARMLESS BUYER GROUP WITH RESPECT THERETO.

Majeure”).  If delivery is to be delayed by a Force Majeure, then Supplier shall immediately notify Buyer in writing and Buyer may either (x) extend the time of performance or (y) terminate all, or a part thereof, of any uncompleted portion of an order at no cost or penalty to Buyer.
7.    DELIVERY AND SCHEDULING
Supplier shall deliver Items in accordance with the delivery schedule set forth in the Purchase Order.

All Items shall be received subject to Buyer’s inspection, testing, approval and acceptance at Buyer’s premises, notwithstanding any inspection or testing at Supplier’s premises or any prior payment for such Items.  Failure by Buyer to inspect and accept or reject the Items or any part thereof, or failure to detect defects by inspection, will not relieve Supplier from responsibility for defects or impose liabilities on Buyer therefor.  Items rejected by Buyer as not conforming to the Purchase Order may be returned to Supplier at Supplier’s risk of loss and expense and, at Buyer’s request, shall promptly be repaired or replaced.
9.    REPRESENTATIONS AND WARRANTIES
A.

Buyer may return at Supplier’s risk of loss and expense any Items in excess of the quantity stated in the Purchase Order.  As directed by Buyer, freight shall be either managed by Supplier or Buyer.

Acute Effects

Chronic Effects

 
:  a. Silicosis: Respirable crystalline silica (quartz) can cause silicosis, a fibrosis (scarring) of the lungs. 
 
    Silicosis may be progressive; it may lead to disability and death.

b. Lung Cancer: Crystalline silica (quartz) inhaled from occupational sources is classified as carcinogenic to humans.

c. Tuberculosis: Silicosis increases the risk of tuberculosis.

d. Autoimmune and Chronic Kidney Diseases: Some studies show excess numbers of cases of scleroderma, connective tissue disorders, lupus, rheumatoid arthritis, chronic kidney diseases and end-stage kidney disease in workers exposed to respirable crystalline silica.

e. Non-Malignant Respiratory Diseases (other than silicosis): Some studies show an increased  
incidence in chronic bronchitis and emphysema in workers exposed to respirable crystalline silica.

:  Contact may cause dryness or moderate skin irritation.
:  May cause moderate to severe irritation of the eyes, including discomfort, pain, redness and swelling. :  May be harmful if swallowed.
:  One form of silicosis, Acute Silicosis, can occur with exposures to very high concentrations of 
 
    respirable crystalline silica over a very short time period, sometimes as short as 6 months. The
symptoms of acute silicosis include (but are not limited to) progressive shortness of breath, fever, cough and weight loss. Acute silicosis is fatal.
:  The adverse health effects -- lung disease, silicosis, cancer, autoimmune disease, tuberculosis, and 
 
    nephrotoxicity -- are chronic effects.

Signs and Symptoms of Exposure

Medical Conditions Aggravated by Exposure

 

:  There are generally no signs or symptoms of exposure to crystalline silica (quartz). Often, chronic 
 
    silicosis has no symptoms. The symptoms of chronic silicosis, if present, are shortness of breath,
wheezing, cough and sputum production. The symptoms of acute silicosis are the same as those associated with chronic silicosis; additionally, weight loss and fever may also occur. The symptoms of scleroderma include thickening and stiffness of the skin, particularly in the fingers, shortness of breath, difficulty swallowing and joint problems.
:  The condition of individuals with lung disease (e.g., bronchitis, emphysema, chronic obstructive 
 
    pulmonary disease) can be aggravated by exposure.

:  Do not use product for abrasive and/or sand blasting. Avoid generating dust. Do not breathe dust. Do 
 
    not rely on your sight to determine if dust is in the air. Respirable crystalline silica dust may be in the
air without a visible dust cloud.

Use adequate exhaust ventilation and dust collection. Maintain and test ventilation and dust collection equipment. Use all available work practices to control dust exposures, such as water sprays. Practice good housekeeping. Do not permit dust to collect on walls, floors, sills, ledges, machinery, or
equipment. Keep airborne dust concentrations below permissible exposure limits.

Where necessary to reduce exposures below the PEL or other applicable limit (if lower than the PEL), wear a respirator approved for silica containing dust when using, handling, storing or disposing of this product or bag. See Section 8, for further information on respirators. Do not alter
the respirator. Do not wear a tight-fitting respirator with facial hair such as a beard or mustache that prevents a good face to face piece seal between the respirator and face. Maintain, clean, and fit test respirators in accordance with applicable standards. Wash or vacuum clothing that has become
dusty.

IARC - The International Agency for Research on Cancer ("IARC") concluded that “crystalline silica in the form of quartz or cristobalite dust is carcinogenic to humans (Group 1)”. For further information on the IARC evaluation, see IARC Monographs on the Evaluation of Carcinogenic Risks to Humans,
Volume 100C,"A Review of Human Carcinogens: Arsenic, Metals, Fibres and Dusts " (2011).

The American College of Occupational and Environmental Medicine (“ACOEM”) notes: “In 1996,  
[IARC] re-classified silica as a Class I human lung carcinogen, based on sufficient animal and human data. Although the degree of increased risk varies (with relative risks ranging from 1.3 to 6.9), the risk appears to be greatest in workers with silicosis who smoke. The cancer risk to silica-exposed workers without silicosis (especially if they are not smokers) is less clear despite continuing research, some of which has yielded disparate results.” ACOEM, “Medical Surveillance of Workers Exposed to  
Crystalline Silica”, June 2005.

The EU Scientific Committee for Occupational Exposure Limits (SCOEL) concluded in June 2002 
 
(SCOEL Sum Doc. 94-final): “The main effect in humans of inhalation of respirable silica dust is
silicosis. There is sufficient information to conclude that the relative risk of lung cancer is increased in persons with silicosis (and apparently, not in employees without silicosis exposed to silica dust in
quarries and in the ceramic industry). Therefore preventing the onset of silicosis will also reduce the cancer risk.”

:  May cause damage to organs through prolonged or repeated exposure.

The method of exposure that can lead to the adverse health effects described below is inhalation.

Silicosis: The major concern is silicosis, caused by the inhalation of respirable crystalline silica dust. Silicosis can exist in several forms, chronic (or ordinary), accelerated, or acute.

Chronic or Ordinary Silicosis is the most common form of silicosis, and can occur after many

Silica Sand 
Safety Data Sheet 

years (15 to 20 or more) of prolonged repeated inhalation of relatively low levels of airborne 
respirable crystalline silica dust. It is further defined as either simple or complicated silicosis. 
Simple silicosis is characterized by lung lesions (shown as radiographic opacities) less than 1 
centimeter in diameter, primarily in the upper lung zones. Often, simple silicosis is not associated  
with symptoms, detectable changes in lung function or disability. Simple silicosis may be  
progressive and may develop into complicated silicosis or progressive massive fibrosis (PMF).  
Complicated silicosis or PMF is characterized by lung lesions (shown as radiographic opacities)  
greater than 1 centimeter in diameter. Although there may be no symptoms associated with  
complicated silicosis or PMF, the symptoms, if present, are shortness of breath and cough.  
Complicated silicosis or PMF may be associated with decreased lung function and may be  
disabling. Advanced complicated silicosis or PMF may lead to death. Advanced complicated  
silicosis or PMF can result in heart disease secondary to the lung disease (cor pumonale). 

Accelerated Silicosis can occur with prolonged repeated inhalation of high concentrations of 
respirable crystalline silica over a relatively short period; the lung lesions can appear within five 
(5) years of initial exposure. Progression can be rapid. Accelerated silicosis is similar to chronic 
 
or ordinary silicosis, except that lung lesions appear earlier and progression is more rapid. 

Acute Silicosis can occur after the repeated inhalation of very high concentrations of respirable 
 
crystalline silica over a short time period, sometimes as short as a few months. The symptoms of 
 
acute silicosis include progressive shortness of breath, fever, cough, weakness and weight loss. 
 
Acute silicosis is fatal. 

Autoimmune Diseases: Several studies have reported excess cases of several autoimmune 
 
disorders, -- scleroderma, systemic lupus erythematosus, rheumatoid arthritis -- among silica-
 
exposed workers). 

Tuberculosis: Individuals with silicosis are at increased risk to develop pulmonary tuberculosis, if exposed to tuberculosis bacteria. Individuals with chronic silicosis have a three-fold higher risk of contracting tuberculosis than similar individuals without silicosis. 

Kidney Disease: Several studies have reported excess cases of kidney diseases, including end  
stage renal disease, among silica-exposed workers. For additional information on the subject,  
the following may be consulted: "Kidney Disease and Silicosis”, Nephron, Volume 85, pp. 14-19  
(2000). 

Non-Malignant Respiratory Diseases: The reader is referred to Section 3.5 of the NIOSH Special Hazard Review cited below, for information concerning the association between  
exposure to crystalline silica and chronic bronchitis, emphysema and small airways disease. There are studies that disclose an association between dusts found in various mining  
occupations and non-malignant respiratory diseases, particularly among smokers. It is unclear whether the observed associations exist only with underlying silicosis, only among smokers, or result from exposure to mineral dusts generally (independent of the presence or absence of crystalline silica, or the level of crystalline silica in the dust). 

Sources of information: 
The NIOSH Hazard Review - Occupational Effects of Occupational Exposure to Respirable 
Crystalline Silica published in April 2002 summarizes and discusses the medical and 
epidemiological literature on the health risks and diseases associated with occupational 
exposures to respirable crystalline silica. The NIOSH Hazard Review should be consulted for 
additional information, and citations to published studies on health risks and diseases associated  
with occupational exposure to respirable crystalline silica. The NIOSH Hazard Review is

EXHIBIT G
Rail Car Agreement
This Car Usage Agreement (this “Agreement”), executed and effective as of the ____ day of _______________, 2015 is between Performance Technologies, LLC, an Oklahoma limited liability Buyer (“Buyer”), and Superior Silica Sands LLC, a Texas limited liability company (“Supplier”).  Buyer and Supplier may be hereinafter referred to as the “Parties” or, individually, as a “Party.”
WHEREAS, Buyer and Supplier have entered into that certain Purchase Option Agreement dated on or about the date hereof (the “Option Agreement”);
WHEREAS, the Option Agreement provides that the Parties will enter into a Car Usage Agreement in the form of Exhibit “G” attached thereto;
WHEREAS, the Parties intend for this Agreement to constitute the Car Usage Agreement referenced in the Option Agreement:
NOW, THEREFORE, in consideration of the foregoing premises and other good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parties agree as follows:
1.    Usage of Terms.  The term “Cars” refers to any and all rail cars used in connection with the relationship between the Parties and related to the Option Agreement.  The Party supplying the Car or Cars is referred to herein as the “Car Provider,” and the Party utilizing the Car or Cars is referred to as the “Car User.”
2.    Damage and Repairs.  Car User agrees to maintain the Cars in good repair and condition in accordance with all Applicable Laws, as defined below, and the Interchange Rules, as defined below.  Car User shall be responsible for any damages and/or repairs that result from its use of the Cars and that would otherwise be the responsibility of Car Provider including, but not limited to, damage to gates and hatches, but excluding repairs for which the owner of the Cars or the railroad is responsible.
3.    Excess Miles.  To the extent Car Provider is responsible for excess mileage charges on the Cars, Car User shall be responsible, and shall promptly pay to Car Provider, these charges on a prorated basis.  For example, if Car Provider is obligated to pay $0.03 per mile for each mile over 30,000 in a calendar year, which equates to 2,500 miles per month, and if Car User has the Cars for one month and the Cars travel 3,200 miles that month, Car User shall pay Car Provider for each Car (700 x $0.03) which travelled this distance.  The Parties will, in good faith, share information about their contractual mileage obligations.

*** Certain information in this document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions.

4.    Car Cleaning.  Unless waived by Car Provider, Car User shall return the Cars to Car Provider clean and free from any residue.  Car User shall be responsible for any costs which result from the Cars being returned without having been adequately cleaned.
5.    Use.  Car User must receive prior written approval from Car Provider if the Cars are to be used to haul any commodity other than the Materials, as defined in the Option Agreement Exhibit “B” Material Specifications.  Car User agrees to use the Cars in compliance with all applicable laws, regulations and rules (collectively, “Applicable Law”) including, without limitation, as specified in the Association of American Railroad’s Rules for Interchange or any successor thereto (the “Interchange Rules”), of any governmental or quasi-governmental body or agency having jurisdiction over Car User or the Cars.  No Cars shall be used for the transport of explosives, flammable products or other hazardous or environmentally regulated commodities.  Car User agrees that the Cars shall remain free of liens and charges of any kind arising through Car User, and Car User shall not assign or sublease its rights hereunder.
6.    Overloaded Cars.  Any costs or fees (including, but not limited to, fees for removal of excess lading and Car storage) resulting from the Cars being overloaded while in service to Car User will be the obligation of Car User regardless of whether the invoices for such costs are directed to Car User or Car Provider.
7.    Usage Outside of Continental United States.  Car User shall not use the Cars outside of the continental United States without prior written consent of Car Provider, which consent may be withheld in Car Provider’s sole discretion.  In the event Cars are used outside of the continental United States (with or without the consent of Car Provider), Car User shall assume full responsibility for all costs, taxes, duties or other charges incidental to such use.
8.    Timely Return of Cars.  Car Provider may request Car User to return Car(s) at Car Provider’s sole discretion, for any reason, including but not limited to, adjusting Car fleet size to conform to the obligations of the Option Agreement, retiring Cars due to lease expiration, Car User’s reallocation of Cars to other uses outside of this Agreement.  Car User agrees to return the identified Car(s) to Car Provider within 60 days of Car Provider’s written request (the “Car Return Period”).  Car User acknowledges that Car Provider may be exposed to certain costs if the Cars are not returned by Car User within the Car Return Period.  These include, but are not limited to, costs associated with the termination of Car Provider’s railcar lease(s) and Car Provider’s monthly lease expense for Cars retained by Car User beyond the Car Return Period.  To the extent Car Provider becomes obligated for such costs due to Car User’s inability or unwillingness, regardless of the reason, to return the Cars in a timely fashion, Car User shall reimburse Car Provider for such costs.
9.    DISCLAIMER; LIMITATION OF LIABILITY.  CAR PROVIDER IS NOT A MANUFACTURER OR REPRESENTATIVE THEREOF, OR MERCHANT OR DEALER WITH RESPECT TO THE CARS.  CAR PROVIDER MAKES NO REPRESENTATIONS OR

CAR PROVIDER SHALL IN NO EVENT BE LIABLE FOR ANY PUNITIVE, SPECIAL, CONSEQUENTIAL, OR INCIDENTAL DAMAGES ARISING OUT OF THIS AGREEMENT OR IN CONNECTION WITH ANY CAR.
10.    Release and Indemnities.

12.    No Consequential Damages.

 Re: Offer of Employment 

Dear Chip, 
 I am pleased to confirm our employment offer for
you to join RigNet (also referred to as the “Company”) as Senior Vice President and Chief Financial Officer, based in Houston, Texas, and reporting directly to Mark B. Slaughter, Chief Executive Officer & President. This
position will commence with a bi-weekly salary of $12,500.00, which equates to $325,000.00 annually. You will be entitled to participate in the Company’s standard benefits package and to 184 hours of personal time per
calendar year, the latter of which will be prorated should your start date fall within the year. Details on benefits and personal time are included in the accompanying materials. 

You will be a participant in the Company’s Short-Term Incentive Plan (“STIP”) beginning in 2016, with a target payout of 70% of your
base salary. The STIP has historically been funded from the Company’s financial performance compared against annual plan targets, with payouts to participants based on financial performance and the degree of achievement of assigned personal
objectives. A copy of the STIP will be provided to you upon your commencement of employment. 
 You will also be recommended to RigNet’s Board of
Directors at its regularly-scheduled meeting in March, 2016 for participation in the Company’s Long-Term Incentive Plan (“LTIP”) at 140% of your annual base salary. LTIP has been historically awarded annually and in a
combination of restricted stock and stock options. For Named Executive Officers, including your position, the Company is considering in 2016 the introduction of performance-based incentives that would be part of the mix. Stock options are awarded
with a strike price “at the money”, vest in equal amounts over four years and have a ten-year life. Restricted stock has restrictions that lapse in equal amounts over four years. As noted above, it is expected that the 2016 LTIP award will
include time-based restricted stock and/or stock options as well as performance shares that will have three-year cliff vesting. 
 As further inducement to
join the RigNet team, we are offering you a sign-on bonus of $455,000, with $330,000 to be provided in equity, and the balance, or $125,000, to be provided in cash. The equity award will be awarded to you on or shortly after your start date,
which you have indicated will be on December 8, 2015. The equity award will be time-based, with 70% of the amount nominated in stock options and 30% in restricted stock or equivalents. Standard vesting will apply as per the preceding paragraph.
The cash component of the sign-on will be made in January, 2016. 
 This offer is contingent upon a clean background check and pre-employment drug screen.
Please note you will need to complete the proper paperwork for both pre-employment items within three calendar days of signing the offer letter. Your employment with us is for no set period of time and may be terminated by either you or us, with or
without cause, at any time, with or without notice. Further information regarding the Arbitration Agreement, Drug & Alcohol Policy, and Confidentiality Agreement and Invention Assignment Agreement can be found in the attached agreements,
which will require your signature before you begin employment.
