On May17, 2017, Solaris Oilfield Infrastructure, Inc. (the
Company) completed its initial public offering (the Offering) of
10,100,000 shares of the Companys ClassA common stock, par value
$0.01 per share (Class A Common Stock), at a price to the public
of $12.00 per share ($11.28 net of underwriting discounts and
commissions), to the Companys Registration Statement on FormS-1
(File No.333-216721), (as amended, the Registration
Statement).The material terms of the Offering are described in
the prospectus, dated May11, 2017 (the Prospectus), filed by the
Company with the Securities and Exchange Commission (the
Commission) on May15, 2017. The Company granted the underwriters
an option for a period of 30 days to purchase up to an additional
1,515,000 shares of ClassA Common Stock at the initial offering
price.

Registration Rights Agreement

On May17, 2017, in connection with the closing of the Offering,
the Company entered into a Registration Rights Agreement (the
Registration Rights Agreement) with certain shareholders
identified on the pages thereto as the Holders (the Holders).

to the Registration Rights Agreement, at any time after 180 days
after the date of the Prospectus, subject to the limitations set
forth therein, the Holders have the right to require the Company
by written notice to prepare and file a registration statement
registering the offer and sale of a number of their shares of
ClassA Common Stock. Reasonably in advance of the filing of any
such registration statement, the Company is required to provide
notice of the request to all other Holders, who may participate
in the registration. The Company is required to use all
commercially reasonable efforts to maintain the effectiveness of
any such registration statement until all shares covered by such
registration statement have been sold. Subject to certain
exceptions, the Company is not obligated to effect such a
registration within 90 days after the closing of any underwritten
offering of shares of ClassA Common Stock. The Company is also
not obligated to effect any registration where such registration
has been requested by the holders of Registrable Securities (as
defined in the Registration Rights Agreement) which represent
less than $35 million, based on the five-day volume weighted
average trading price of the ClassA Shares on the New York Stock
Exchange.

In addition, to the Registration Rights Agreement, the Holders
have the right to require the Company, subject to certain
limitations set forth therein, to effect a distribution of any or
all of their shares of ClassA Common Stock by means of an
underwritten offering. Further, subject to certain exceptions, if
at any time the Company proposes to register an offering of
ClassA Common Stock or conduct an underwritten offering, whether
or not for its account, then the Company must notify the Holders
of such proposal at least five business days before the
anticipated filing date or commencement of the underwritten
offering, as applicable, to allow them to include a specified
number of their shares in that registration statement or
underwritten offering, as applicable.

These registration rights are subject to certain conditions and
limitations, including the right of the underwriters to limit the
number of shares to be included in a registration or offering and
the Companys right to delay or withdraw a registration statement
under certain circumstances. The Company will generally pay all
registration expenses in connection with its obligations under
the Registration Rights Agreement, regardless of whether a
registration statement is filed or becomes effective.

The obligations to register shares under the Registration Rights
Agreement will terminate as to any Holder when the Registrable
Securities held by such Holder are no longer subject to any
restrictions on trading under the provisions of Rule 144 under
the Securities Act of 1933, as amended (the Securities Act),
including any volume or manner of sale restrictions. Registrable
Securities means all shares of ClassA Common Stock owned at any
particular point in time by a Holder other than shares (i)sold to
an effective registration statement under the Securities Act,
(ii)sold in a transaction to Rule 144 under the Securities Act,
(iii)that have ceased to be outstanding or (iv)that are eligible
for resale without restriction and without the need for current
public information to any section of Rule 144 under the
Securities Act.

The foregoing description of the Registration Rights Agreement is
qualified in its entirety by reference to the full text of the
Registration Rights Agreement, which is attached as Exhibit 4.1
to this Current Report on Form 8-K and incorporated in this
Item1.01 by reference.

Tax Receivable Agreement

On May17, 2017, in connection with the Offering, the Company
entered into a Tax Receivable Agreement (the TRA) with the
members of Solaris Oilfield Infrastructure, LLC (Solaris LLC),
including certain of the Companys executive officers (the TRA
Holders). This agreement generally provides for the payment by
the Company of 85% of the net cash savings, if any, in U.S.
federal, state and local income tax and franchise tax that the
Company actually realizes (computed using simplifying assumptions
to address the impact of state and local taxes) or is deemed to
realize in certain circumstances in periods after the Offering as
a result of (i)certain increases in tax basis that occur as a
result of the Companys acquisition (or deemed acquisition for
U.S. federal income tax purposes) of all or a portion of such TRA
Holders units in Solaris LLC (Solaris LLC Units) in connection
with the Offering or to the exercise of the Redemption Right or
the Call Right (as defined in the TRA) and (ii)imputed interest
deemed to be paid by the Company as a result of, and additional
tax basis arising from, any payments the Company makes under the
Tax Receivable Agreement. The term of the TRA commences on May17,
2017 and continues until all such tax benefits have been utilized
or expired, unless the Company exercises its right to terminate
the TRA. The payments under the TRA will not be conditioned upon
a TRA Holder having a continued ownership interest in either
Solaris LLC or the Company.

If the Company elects to terminate the TRA early, it would be
required to make an immediate payment equal to the present value
of the anticipated future tax benefits subject to the TRA (based
upon certain assumptions and deemed events set forth in the TRA).
In addition, payments due under the TRA will be similarly
accelerated following certain mergers or other changes of
control.

The foregoing description is not complete and is qualified in its
entirety by reference to the full text of the TRA, which is
attached as Exhibit 10.1 to this Current Report on Form 8-K and
incorporated in this Item1.01 by reference.

First Amendment to Credit Agreement

On May17, 2017, in connection with the Offering, the Company
entered into a First Amendment (the First Amendment) to the
Credit Agreement, dated as of December1, 2016 (the the Credit
Agreement and, as amended by the First Amendment, the Amended
Credit Facility), by and among the Company, as borrower, each of
the lenders party thereto and Woodforest National Bank, as
administrative agent (the Administrative Agent). The First
Amendment, among other things, modified the terms of the Credit
Agreement to (i)increase the Revolving Facility (as defined in
the Prospectus) from $1.0 million to $20.0 million, (ii)decrease
the Advance Loan Facility (as defined in the Prospectus) from
$10.0 million to $0 and (iii)amend both the scheduled maturity
date of the Revolving Facility and the Advance Loan Facility to
be May17, 2021. Additionally, the First Amendment increased the
accordion feature of the Revolving Facility from $1.0 million to
$10.0 million, which accordion may be elected by the Company at
any time prior to the scheduled maturity date of the Revolving
Facility so long as no default or event of default shall have
occurred and be continuing and provided that no lender has any
obligation to increase its own revolving credit commitment.

The Amended Credit Agreement permits extensions of credit up to
the lesser of $20.0 million and a borrowing base that is
determined by calculating the amount equal to the sum of (i)80%
of the Eligible Accounts (as defined in the Amended Credit
Agreement), (ii)65% of the Eligible Inventory/Equipment Value
(Appraised) (as defined in the Amended Credit Agreement) and
(iii)75% of the Eligible Inventory/Equipment Value (New Build,
Acquired or Upgraded) (as defined in the Amended Credit
Agreement). The borrowing base is calculated on a monthly basis
to a borrowing base certificate delivered to the Administrative
Agent and an annual appraisal on the equipment delivered to the
Administrative Agent (provided that the Administrative Agent may,
at its discretion, require a desktop appraisal on equipment every
six months).

Borrowings under the Amended Credit Facility continue to bear
interest at one-month LIBOR plus an applicable margin and
interest continues to be payable monthly. The First Amendment
decreased the applicable margins to an applicable margin range
from 3.00% to 4.00% depending on our leverage ratio. The First
Amendment also increased the monthly commitment fee we pay on
undrawn amounts of the Revolving Facility to a range from 0.1875%
to 0.50% depending on our leverage ratio; provided, however that
we will not be required to pay such commitment fee for any month
when we have outstanding borrowings greater than 50.0% of the
commitments under the Revolving Facility.

The Amended Credit Agreement requires that we maintain, at all
times, a ratio of net funded indebtedness to consolidated EBITDA
of not more than 2.50 to 1.00, provided that net funded
indebtedness is subject to a cash adjustment with respect to any
unrestricted cash and cash equivalents of the Borrower and its
subsidiaries in an amount equal to the lesser of $10.0 million or
50% of unrestricted cash and cash equivalents of the Company and
its subsidiaries. The Amended Credit Facility also requires that
we maintain, at all times, a ratio of consolidated EBITDA to
fixed charges of not less than 1.25 to 1.00. Additionally, our
capacity to make capital expenditures is capped at $80.0 million
for each fiscal year plus, for fiscal years beginning on
January1, 2019, any unused availability for capital expenditures
from the immediately preceding fiscal year; provided, however
that we are permitted to make any capital expenditures in an
amount equal to the proceeds of equity contributions made to the
Company used to fund such capital expenditures.

The foregoing description is not complete and is qualified in its
entirety by reference to the full text of the First Amendment,
which is attached as Exhibit 10.2 to this Current Report on Form
8-K and incorporated in this Item1.01 by reference.
