(collectively, the &ldquo;Obligations&rdquo;), are unsecured general obligations of First Horizon to pay the&nbsp;deferred&nbsp;compensation&nbsp;in
the future in accordance with the terms of the Deferred Compensation Plan. The Obligations rank equally with other unsecured and
unsubordinated indebtedness of First Horizon from time to time outstanding and payable from the general assets of First Horizon.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 36pt; background-color: white">The amount of compensation
deferred by each participating service provider (a &ldquo;Participant&rdquo;) is based on elections by each Participant. First
Horizon may also make discretionary contributions to Participant accounts, but currently has no plan to do so. This Registration
Statement relates to $10,727,419 in the Obligations assumed by First Horizon, as successor to IBKC, following the consummation
of the Merger. Each obligation will be treated as invested in one or more investment funds chosen by each Participant from a list
of investment funds designated by First Horizon; provided however, that First Horizon may designate the use of a particular investment
fund for amounts contributed by it as employer contributions. The available investment funds will include a fund that is deemed
to be invested in the common stock of First Horizon. The Obligations will be adjusted to reflect the investment results, whether
positive or negative, of the selected investment fund(s), including any appreciation or depreciation. The Obligations will be payable
to Participants in cash upon the distribution event or date selected by the Participant.</P>

Plan is not required to be funded, and the Obligations are not secured. The amount of compensation deferred by each Participant
is subject to all the risks of First Horizon&rsquo;s business and may be deposited, invested or expended in any manner whatsoever
by First Horizon. First Horizon may choose to establish a trust for the purpose of funding the Obligations. Participants and their
beneficiaries, however, have no secured interest or special claim to the assets of any trust, which would be subject to the payment
of claims of creditors of First Horizon upon the insolvency or bankruptcy of First Horizon.</P>

are not subject to redemption, in whole or in part, prior to the scheduled payment dates or events, although the Obligations could
be redeemed in the event of termination of the Deferred Compensation Plan in accordance with Section 409A of the Internal Revenue
Code of 1986, as amended, and the regulations and guidance thereunder (&ldquo;Section 409A&rdquo;). First Horizon reserves the
right to amend or terminate the Deferred Compensation Plan at any time, except that no such amendment or termination may reduce
the balance of a Participant&rsquo;s plan account or may affect the terms of payment unless permitted under Section 409A.</P>

are not convertible into another security of First Horizon. The Obligations will not have the benefit of any affirmative or negative
covenant on the part of First Horizon. The trustee or any trust established for purposes of the Deferred Compensation Plan will
not have the authority to take action with respect to the Obligations and each Participant will be responsible for acting independently
with respect to, among other things, the making of elections and the giving of notices.</P>

Tennessee Business Corporation Act (the &ldquo;TBCA&rdquo;) authorize a corporation to provide for the indemnification of officers,
directors, employees and agents in terms sufficiently broad to permit indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities Act. First Horizon adopted the provisions of the Tennessee
statute pursuant to Article Six of First Horizon&rsquo;s bylaws. In addition, First Horizon has a directors&rsquo; and officers&rsquo;
liability insurance policy which provides coverage sufficiently broad to permit indemnification under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the Securities Act.</P>

liability of directors to the corporation or its shareholders for breach of the duty of care. First Horizon has adopted the provisions
of the statute as Article 14 of its restated charter.</P>

and any officers designated by the board of directors, and advance expenses, to the maximum extent not prohibited by law. In accordance
with the foregoing, First Horizon is authorized to enter into individual indemnity agreements with its directors and such officers.
Such indemnity agreements have been approved for all of the directors and certain officers.</P>

directors&rsquo; and officers&rsquo; liability insurance and to advance professional expenses under certain circumstances, the
rules prohibit such institutions from indemnifying a director for certain costs incurred with regard to an administrative or enforcement
action commenced by any federal banking agency that results in a final order or settlement pursuant to which the director is assessed
a civil money penalty, removed from office, prohibited from participating in the affairs of an insured depository institution or

Item 4. Description of Securities.
The following description
of the deferred compensation obligations is qualified by reference to the Deferred Compensation Plan, incorporated
by reference as an exhibit to this Registration Statement.
Under the Deferred Compensation Plan,
First Horizon may permit eligible employees, independent contractors and directors to defer a specified percentage of their future
cash compensation from First Horizon. The obligations of First Horizon under the Deferred Compensation Plan, as described below
(collectively, the "Obligations"), are unsecured general obligations of First Horizon to pay the deferred compensation in
the future in accordance with the terms of the Deferred Compensation Plan. The Obligations rank equally with other unsecured and
unsubordinated indebtedness of First Horizon from time to time outstanding and payable from the general assets of First Horizon.
The amount of compensation
deferred by each participating service provider (a "Participant") is based on elections by each Participant. First
Horizon may also make discretionary contributions to Participant accounts, but currently has no plan to do so. This Registration
Statement relates to $10,727,419 in the Obligations assumed by First Horizon, as successor to IBKC, following the consummation
of the Merger. Each obligation will be treated as invested in one or more investment funds chosen by each Participant from a list
of investment funds designated by First Horizon; provided however, that First Horizon may designate the use of a particular investment
fund for amounts contributed by it as employer contributions. The available investment funds will include a fund that is deemed
to be invested in the common stock of First Horizon. The Obligations will be adjusted to reflect the investment results, whether
positive or negative, of the selected investment fund(s), including any appreciation or depreciation. The Obligations will be payable
to Participants in cash upon the distribution event or date selected by the Participant.
The Deferred Compensation
Plan is not required to be funded, and the Obligations are not secured. The amount of compensation deferred by each Participant
is subject to all the risks of First Horizon's business and may be deposited, invested or expended in any manner whatsoever
by First Horizon. First Horizon may choose to establish a trust for the purpose of funding the Obligations. Participants and their
beneficiaries, however, have no secured interest or special claim to the assets of any trust, which would be subject to the payment
of claims of creditors of First Horizon upon the insolvency or bankruptcy of First Horizon.
The Obligations
are not subject to redemption, in whole or in part, prior to the scheduled payment dates or events, although the Obligations could
be redeemed in the event of termination of the Deferred Compensation Plan in accordance with Section 409A of the Internal Revenue
Code of 1986, as amended, and the regulations and guidance thereunder ("Section 409A"). First Horizon reserves the
right to amend or terminate the Deferred Compensation Plan at any time, except that no such amendment or termination may reduce
the balance of a Participant's plan account or may affect the terms of payment unless permitted under Section 409A.
The Obligations
are not convertible into another security of First Horizon. The Obligations will not have the benefit of any affirmative or negative
covenant on the part of First Horizon. The trustee or any trust established for purposes of the Deferred Compensation Plan will
not have the authority to take action with respect to the Obligations and each Participant will be responsible for acting independently
with respect to, among other things, the making of elections and the giving of notices.
Item 5. Interests of Named Experts and Counsel.
The validity of the Obligations offered hereby
has been passed upon by Baker, Donelson, Bearman, Caldwell & Berkowitz, PC.
Item 6. Indemnification of Directors and Officers.
Sections 48-18-501 through 48-18-509 of the
Tennessee Business Corporation Act (the "TBCA") authorize a corporation to provide for the indemnification of officers,
directors, employees and agents in terms sufficiently broad to permit indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities Act. First Horizon adopted the provisions of the Tennessee
statute pursuant to Article Six of First Horizon's bylaws. In addition, First Horizon has a directors' and officers'
liability insurance policy which provides coverage sufficiently broad to permit indemnification under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the Securities Act.
Section 48-12-102 of the TBCA permits the
inclusion in the charter of a Tennessee corporation of a provision, with certain exceptions, eliminating the personal monetary
liability of directors to the corporation or its shareholders for breach of the duty of care. First Horizon has adopted the provisions
of the statute as Article 14 of its restated charter.
First Horizon's shareholders have approved
a provision in Article Six of First Horizon's bylaws pursuant to which First Horizon is required to indemnify each director
and any officers designated by the board of directors, and advance expenses, to the maximum extent not prohibited by law. In accordance
with the foregoing, First Horizon is authorized to enter into individual indemnity agreements with its directors and such officers.
Such indemnity agreements have been approved for all of the directors and certain officers.
Certain rules of the Federal Deposit Insurance
Corporation limit the ability of certain depository institutions, their subsidiaries and their affiliated depository institution
holding companies to indemnify affiliated parties, including institution directors. In general, subject to the ability to purchase
directors' and officers' liability insurance and to advance professional expenses under certain circumstances, the
rules prohibit such institutions from indemnifying a director for certain costs incurred with regard to an administrative or enforcement
action commenced by any federal banking agency that results in a final order or settlement pursuant to which the director is assessed
a civil money penalty, removed from office, prohibited from participating in the affairs of an insured depository institution or
required to cease and desist from or take an affirmative action described in Section 8(b) of the Federal Deposit Insurance Act
(12 U.S.C. § 1818(b)).

Item 9. Undertakings.
The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:
(i) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933;
(ii) to reflect in the prospectus any facts or events
arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually
or in the aggregate, represent a fundamental change in the information set forth in the registration statement; and
(iii) to include any material information with respect
to the plan of distribution not previously disclosed in the registration statement or any material change to such information in
the registration statement;
provided, however, that paragraphs (1)(i) and (1)(ii)
do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports
filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.
(2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the termination of the offering.
The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.
Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions,
or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person
of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification
by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
SIGNATURES

Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing
on Form S-8 and has duly caused this registration statement on Form S-8 to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Memphis and State of Tennessee, on July 15, 2020.
