<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt 0.25in; text-align: justify"><FONT STYLE="font-size: 10pt">On
August 8, 2023, USO and ADM Investor Services, Inc. (&ldquo;ADMIS&rdquo;) entered into a Customer Account Agreement pursuant to
which ADMIS has agreed to serve as an additional FCM for USO. The Customer Account Agreement between USO and ADMIS requires ADMIS to
provide services to USO in connection with the purchase and sale of futures contracts that may be purchased or sold by or through
ADMIS for USO&rsquo;s account. Under this agreement, USO has agreed to pay ADMIS commissions for executing and clearing trades on
behalf of USO.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt 0.25in; text-align: justify"><FONT STYLE="font-size: 10pt">ADMIS&rsquo;s
primary address is 141 W Jackson Boulevard, Suite 2100a, Chicago, IL 60604. ADMIS is registered in the United States with the
CFTC as an FCM providing futures execution and clearing services covering futures exchanges globally. ADMIS is a member of various
U.S. futures and securities exchanges.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt 0.25in; text-align: justify"><FONT STYLE="font-size: 10pt">ADMIS
has been named as a defendant in various legal actions, including arbitrations, class actions and other litigation including those
described below, arising in connection with its activities. Certain of the actual or threatened legal actions include claims for
substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. ADMIS is also involved, in other
reviews, investigations and proceedings (both formal and informal) by governmental and self-regulatory agencies regarding ADMIS&rsquo;s
business, including among other matters, accounting and operational matters, certain of which may result in adverse judgments,
settlements, fines, penalties, injunctions or other relief.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt 0.25in; text-align: justify"><FONT STYLE="font-size: 10pt">ADMIS
contests liability and/or the amount of damages as appropriate in each pending matter. In view of the inherent difficulty of predicting
the outcome of such matters, particularly in cases where claimants seek substantial or indeterminate damages or where investigations
and proceedings are in the early stages, ADMIS cannot predict the loss or range of loss, if any, related to such matters; how
or if such matters will be resolved; when they will ultimately be resolved; or what the eventual settlement, fine, penalty or
other relief, if any, might be. Subject to the foregoing, ADMIS believes, based on current knowledge and after consultation with
counsel, that the outcome of such pending matters will not have a material adverse effect on the consolidated financial condition
of ADMIS.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 10pt 0.25in; text-align: justify"><FONT STYLE="font-size: 10pt">On
September 4, 2019, AOT Holding AG (&ldquo;AOT&rdquo;) filed a putative class action under the U.S. Commodities Exchange Act in
federal district court in Urbana, Illinois, alleging that ADMIS sought to manipulate the benchmark price used to price and settle
ethanol derivatives traded on futures exchanges. On March 16, 2021, AOT filed an amended complaint adding a second named plaintiff
Maize Capital Group, LLC (&ldquo;Maize&rdquo;). AOT and Maize allege that members of the putative class suffered &ldquo;hundreds
of millions of dollars in damages&rdquo; as a result of ADMIS&rsquo;s alleged actions. On July 14, 2020, Green Plains Inc. and
its related entities (&ldquo;GP&rdquo;) filed a putative class action lawsuit, alleging substantially the same operative facts,
in federal court in Nebraska, seeking to represent sellers of ethanol. On July 23, 2020, Midwest Renewable Energy, LLC (&ldquo;MRE&rdquo;)
filed a putative class action in federal court in Illinois alleging substantially the same operative facts and asserting claims
under the Sherman Act. On November 11, 2020, United Wisconsin Grain Producers LLC (&ldquo;UWGP&rdquo;) and five other ethanol
producers filed a lawsuit in federal court in Illinois alleging substantially the same facts and asserting claims under the Sherman
Act and Illinois, Iowa, and Wisconsin law.</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 0pt 0.25in; text-align: justify"><FONT STYLE="font-size: 10pt">The
court granted ADMIS&rsquo;s motion to dismiss the MRE and UWGP complaints without prejudice on August 9, 2021 and September 28,
2021, respectively. On August 16, 2021, the court granted ADMIS&rsquo;s motion to dismiss the GP complaint, dismissing one claim
with prejudice and declining jurisdiction over the remaining state law claim. MRE filed an amended complaint on August 30, 2021,
which ADMIS moved to dismiss on September 27, 2021. UWGP filed an amended complaint on October 19, 2021, which ADMIS moved to
dismiss on December 9, 2021. On October 26, 2021, GP filed a new complaint in Nebraska federal district court, alleging substantially
the same facts and asserting a claim for tortious interference with contractual relations.</FONT></P>

denies liability, and is vigorously defending itself in these actions. As these actions are in pretrial proceedings, ADMIS is

ADMIS has not passed upon the adequacy or accuracy of this prospectus. ADMIS will not act in any supervisory capacity with respect
