shall have been executed and delivered by a duly authorized officer of the Company. 
 (q) DTC. The Securities shall be

 (r) No Default. There shall exist at and as of the Closing Date no
conditions that would constitute a default (or an event that with notice or the lapse of time, or both, would constitute a default) under (i) the Amended and Restated Loan and Security Agreement, dated as of November 18, 2005, entered into
among SBA Properties, Inc., the additional borrowers that became a party thereto (see below) and SBA CMBS-1 Depositor LLC, as amended, supplemented or otherwise modified from time to time (the “Mortgage Loan”) or (ii) the Second
Amended and Restated Credit Agreement, dated as of February 7, 2014, among SBA Senior Finance II LLC, as borrower and the several lenders from time to time parties thereto (the “Credit Agreement”). 

(s) Market Events. Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following:
(i) trading in securities generally on the NYSE, the NASDAQ Global Select Market, the NASDAQ Global Market or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the Company on any exchange or in the

outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity, crisis or emergency if, in the judgment of the Representative, the effect of
any such attack, outbreak, escalation, act, declaration, calamity, crisis or emergency makes it impractical or inadvisable to proceed with the completion of the offering or sale of and payment for the Securities, or (v) the occurrence of any
other calamity, crisis (including without limitation as a result of terrorist activities), or material adverse change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the
United States shall be such) as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the public offering, sale or delivery of the Securities being delivered on the Closing Date on the terms and in the
manner contemplated by this Agreement, the Time of Sale Information and the Final Offering Memorandum or that, in the judgment of the Representative, would materially and adversely affect the financial markets or the markets for the Securities
and/or debt securities. 
 (t) Additional Documents. On or prior to the Closing Date, the Company shall have furnished to the
Representative such further certificates and documents as the Representative may reasonably request. 
 All opinions, letters, certificates
and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers. 

7. Indemnification and Contribution. 

(a) Indemnification of the Initial Purchasers. The Company agrees to indemnify and hold harmless each Initial Purchaser, their
respective affiliates, directors and officers and each person, if any, who controls such Initial Purchasers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses,
claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out
of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Final Offering Memorandum
(or any amendment or supplement thereto), in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities or in any information provided by the Company
pursuant to Section 4(e), any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except
insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any Initial Purchasers’ Information.

  
 25 

 (b) Indemnification of the Company. Each Initial Purchaser agrees, severally and not
jointly, to indemnify and hold harmless the Company, each of its affiliates, directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any Initial Purchasers’ Information furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of
the other Time of Sale Information, any Issuer Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto). 

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand
shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person
against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph
(a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying
Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have
notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to
represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding,
as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have
reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties)
include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the
Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate 

  
 26 

 
firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Initial
Purchasers, their respective affiliates, directors and officers and any control persons of the Initial Purchasers shall be designated in writing by the Initial Purchasers and any such separate firm for the Company, its directors and officers and any
control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a
final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an
Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding
effected without its written consent if (i) such settlement is entered into more than thirty (30) calendar days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the
Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of
which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and
substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by
or on behalf of any Indemnified Person. 
 (d) Contribution. If the indemnification provided for in paragraphs (a) and
(b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person
thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company
on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds
(before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering
price of the Securities. The relative fault of the Company on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or 

  
 27 

 
alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to the information supplied by the Company or Initial Purchasers’ Information
supplied by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e) Limitation on Liability. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable
by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such
Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall the Initial Purchasers be required to contribute any amount in excess of the amount by which the total discounts
and commissions received by the Initial Purchasers with respect to the offering of the Securities exceeds the amount of any damages that the Initial Purchasers have otherwise been required to pay by reason of such untrue or alleged untrue statement
or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to paragraph (d) above are several in proportion to their respective purchase obligations hereunder and not joint. 

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or
remedies that may otherwise be available to any Indemnified Person at law or in equity. 
 8. Defaulting Initial Purchasers. If, on
the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to purchase the Securities that the defaulting Initial Purchasers agreed
but failed to purchase on such Closing Date in the respective proportions which the principal amount of the Securities set forth opposite the name of each remaining non-defaulting Initial Purchaser in Schedule 1 hereto bears to the aggregate
principal amount of the Securities set forth opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule 1 hereto; provided, however, that the remaining non-defaulting Initial Purchasers shall not be obligated to
purchase any of the Securities on such Closing Date if the aggregate principal amount of the Securities that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 9.09% of the aggregate principal
amount of the Securities to be purchased on such Closing Date and any remaining non-defaulting Initial Purchaser shall not be obligated to purchase more than 110% of the principal amount of the Securities that it agreed to purchase on such Closing
Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them,
all the Securities to be purchased on such Closing Date. If the remaining Initial Purchasers do not elect to 

  
 28 

 
purchase the principal amount of Securities that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such Closing Date this Agreement shall terminate without
liability on the part of any non-defaulting Initial Purchaser or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Section 10. As used in this Agreement, the term
“Initial Purchaser” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 8, purchases Securities that a defaulting Initial
Purchaser agreed but failed to purchase. 
 Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may
have to the Company for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Securities of a defaulting or withdrawing Initial Purchaser, either the remaining Initial Purchasers or the Company may
postpone the Closing Date for up to seven (7) full Business Days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Final
Offering Memorandum or in any other document or arrangement. 
 9. Termination. The obligations of the Initial Purchasers hereunder
may be terminated by the Initial Purchasers, in the absolute discretion of the Initial Purchasers, by notice given to the Company prior to the delivery of and payment for the Securities if, prior to that time, any of the events described in
Section 6(e), 6(f), 6(l), 6(m) and 6(s) shall have occurred. 
 10. Payment of Expenses. (a) Whether or not the
transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation,
(i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering
Memorandum, any Issuer Written Communication, any Time of Sale Information and the Final Offering Memorandum (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and
distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination
of eligibility for investment of the Securities under the laws of such jurisdictions as the Initial Purchasers may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel
for the Initial Purchasers not to exceed $15,000); (viii) any fees charged by rating agencies for rating the Securities; (ix) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any
counsel to such parties); (x) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; and (xi) all expenses incurred by the Company in connection with any “road
show” presentation to potential investors. 

  
 29 

 (b) If (i) this Agreement is terminated pursuant to Section 9 (other than due to the
events described in Section 6(l) and 6(m)), (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason
permitted under this Agreement, the Company agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this
Agreement and the proposed purchase and resale of the Securities contemplated hereby. 
 11. Persons Entitled to Benefit of
Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of the Initial Purchasers
referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No
purchaser of Securities from the Initial Purchasers shall be deemed to be a successor merely by reason of such purchase. 
 12.
Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company or the Initial Purchasers
pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made
by or on behalf of the Company or the Initial Purchasers. 
 13. Compliance with USA Patriot Act. In accordance with the requirements
of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, which
information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients. 

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term
“affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “Business Day” means any day other than a Saturday, a Sunday or a day on which banking institutions in New York, New York are
authorized or required by law or executive order to remain closed; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “written communication” has the meaning set

fifth sentences of the tenth paragraph and the twelfth paragraph under “Plan of Distribution” in the Final Offering Memorandum. 

  
 30

Rights Agreement Amendment] 

 Exhibit A 

FORM OF 
 SUMMARY OF RIGHTS TO
PURCHASE 
 PREFERRED STOCK 

On June 19, 2012, the Board of Directors (the “Board”) of Navistar International Corporation, a Delaware corporation (the
“Company”), authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of the common stock of the Company, par value $0.10 per share (the “Common Stock”), to stockholders of
record at the close of business on June 29, 2012 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company a unit consisting of one one-thousandth of a share (a “Unit”) of a newly authorized
series of Junior Participating Preferred Stock, Series A, par value $1.00 per share (the “Preferred Stock”), at a purchase price of $140.00 per Unit, subject to adjustment (the “Purchase Price”). The complete terms of the Rights
are set forth in a Rights Agreement, dated as of June 19, 2012, as amended to date, between the Company and Computershare Inc., successor-in-interest to Computershare Shareowner Services LLC, as Rights Agent (the “Rights Agreement”).

 Rights Certificates; Exercise Period. 

Initially, the Rights will be attached to all shares of Common Stock then outstanding, and no separate rights certificates (“Rights
Certificates”) will be distributed. Subject to certain exceptions specified in the Rights Agreement, the Rights will separate from the Common Stock and a distribution date (a “Distribution Date”) will occur upon the earlier of
(i) 10 business days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of twenty percent (20%) or more of the outstanding shares
of Common Stock (the “Stock Acquisition Date”), other than as a result of repurchases of stock by the Company or certain inadvertent actions by certain stockholders or (ii) 10 business days (or such later date as the Board shall
determine) following the commencement of a tender offer or exchange offer that would result in a person or group becoming an Acquiring Person. For purposes of the Rights Agreement, beneficial ownership is defined to include ownership of derivative
securities. 
 Until a Distribution Date, (i) the Rights will be evidenced by the certificates for the Common Stock (or, in the case of
shares reflected on the direct registration system, by the notations in the book-entry account system) and will only be transferable with such Common Stock, (ii) new Common Stock certificates issued after the Record Date will contain a legend
incorporating the Rights Agreement by reference and (iii) the surrender for transfer of any certificates for Common Stock outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such
certificates. Pursuant to the Rights Agreement, the Company reserves the right to require prior to the occurrence of a Triggering Event (as defined below) that, upon any exercise of Rights, a number of Rights be exercised so that only whole shares
of Preferred Stock will be issued. 
 The Rights are not exercisable until a Distribution Date and will expire at 5:00 P.M., New York City
time on July 1, 2014, unless such date is extended or the Rights are earlier redeemed, exchanged or terminated. 

 As soon as practicable after a Distribution Date, Rights Certificates will be mailed to holders
of record of the Common Stock as of the close of business on a Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. Except as otherwise determined by the Board, only shares of Common Stock issued prior
to a Distribution Date will be issued with Rights. 
 Flip-in Trigger. 

In the event that a person or group of affiliated or associated persons becomes an Acquiring Person, except pursuant to an offer for all
outstanding shares of Common Stock which the independent directors determine to be fair and not inadequate and to otherwise be in the best interests of the Company and its stockholders after receiving advice from one or more investment banking
firms, each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of the event set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null
and void. However, Rights are not exercisable following the occurrence of the event set forth above until such time as the Rights are no longer redeemable by the Company as set forth below. Any person who, together with its affiliates and
associates, beneficially owns 20% or more of the outstanding shares of Common Stock as of the time of first public announcement of the Rights Agreement (an “Exempt Person”) shall not be deemed an Acquiring Person, but only for so long as
such person, together with its affiliates and associates, does not, while such person is an Exempt Person, become the Beneficial Owner of a higher percentage of the shares of Common Stock then outstanding (other than as a result of a reduction in
the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company (or any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such plan)) as compared to the percentage of shares of Common Stock outstanding Beneficially Owned by such Exempt Person as of the Exempt Time. 

Flip-over Trigger. 
 In
the event that, at any time following the Stock Acquisition Date, (i) the Company engages in a merger or other business combination transaction in which the Company is not the surviving corporation, (ii) the Company engages in a merger or
other business combination transaction in which the Company is the surviving corporation and the Common Stock of the Company is changed or exchanged, or (iii) 50% or more of the Company’s assets, cash flow or earning power is sold or
transferred, each holder of a Right (except Rights which have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise
price of the Right. The events set forth in this paragraph and in the preceding paragraph are referred to as the “Triggering Events.” 

Exchange Feature. 
 At any
time after a person becomes an Acquiring Person and prior to the acquisition by such person or group of fifty percent (50%) or more of the outstanding Common Stock, the 

 
Board may exchange the Rights (other than Rights owned by such person or group which have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock, or one
one-thousandth of a share of Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per Right (subject to adjustment). 

Equitable Adjustments. 

The Purchase Price payable, and the number of Units of Preferred Stock or other securities or property issuable, upon exercise of the Rights
are subject to adjustment from time to time to prevent dilution (i) in the event of a dividend on the Preferred Stock payable in shares of Preferred Stock, a subdivision or split of outstanding shares of Preferred Stock, a combination or
consolidation of Preferred Stock into a smaller number of shares through a reverse stock split or otherwise, or reclassification of the Preferred Stock, (ii) if holders of the Preferred Stock are granted certain rights, options or warrants to
subscribe for Preferred Stock or convertible securities at less than the current market price of the Preferred Stock, or (iii) upon the distribution to holders of the Preferred Stock of cash (excluding regular quarterly cash dividends), assets,
evidences of indebtedness or of subscription rights or warrants (other than those referred to above). 
 With certain exceptions, no
adjustment in the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price. No fractional Units will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the
Preferred Stock on the last trading date prior to the date of exercise. 
 Redemption Rights. 

At any time until ten business days following the Stock Acquisition Date, the Company may redeem the Rights in whole, but not in part, at a
price of $0.001 per Right (payable in cash, Common Stock or other consideration deemed appropriate by the Board). Immediately upon the action of the Board ordering redemption of the Rights, the Rights will terminate and the only right of the holders
of Rights will be to receive the $0.001 redemption price. 
 Miscellaneous. 

Until a Right is exercised, the holder thereof, as such, will have no separate rights as a stockholder of the Company, including, without
limitation, the right to vote or to receive dividends in respect of Rights. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in
the event that the Rights become exercisable for Common Stock (or other consideration) of the Company or for common stock of the acquiring company or in the event of the redemption of the Rights as set forth above. 

Amendment. 
 Any of the
provisions of the Rights Agreement may be amended by the Board prior to a Distribution Date. After a Distribution Date, the provisions of the Rights Agreement may be amended by the Board in order to cure any ambiguity, to make changes which do not
adversely affect the interests of holders of Rights, or to shorten or lengthen any time period under the Rights Agreement. Notwithstanding the foregoing, no amendment may be made (other than to cure any ambiguity) at a time when the Rights are not
redeemable. 

 Anti-Takeover Effects. 

The Rights may have certain anti-takeover effects. The Rights may cause substantial dilution to any person or group that attempts to acquire
the Company without the approval of the Board. As a result, the overall effect of the Rights may be to render more difficult or discourage a merger, tender offer or other business combination involving the Company that is not supported by the Board.

 A copy of the Rights Agreement has been filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on
Form 8-A or a Current Report on Form 8-K. A copy of the Rights Agreement is available free of charge from the Company. This summary description of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
