|Warrant No. SWA-37 |  | Original Issue Date: October 21, 2010

CUSIP 876851 130

THIS CERTIFIES THAT,for value received, Prairie
Capital IV QP, L.P., or its permitted assigns (the Holder), is entitled to subscribe for and purchase during the period specified in Section 1 hereof 44,525 fully paid and non-assessable shares of Common Stock, $.01 par value
(Common Stock), of TAYLOR CAPITAL GROUP, INC., a Delaware corporation (the Company), at a per share price equal to the Warrant Price, subject to the provisions and upon the terms and conditions
hereinafter set forth. Capitalized terms used herein, but not otherwise defined, shall have meanings provided in Section 10 of this Warrant.

This Warrant was originally issued pursuant to the Securities Purchase Agreement (as may be amended, modified or restated from time to time), dated May 21, 2010, by and among the Company, the initial
Holder and the other investors party thereto (the Purchase Agreement). The Holder acknowledges that this Warrant was issued in connection with a private placement (the Debt Placement) of up to $37,500,000 in
subordinated notes (the Notes) by the Company, in which each investor in the Debt Placement is receiving a warrant on the same terms as this Warrant to purchase twenty-five (25) shares (subject to adjustment as provided
herein) of Common Stock for every $1,000 in face amount of the Notes purchased in the Debt Placement. Accordingly, the Company is issuing, in the aggregate, warrants to purchase an aggregate of up to nine hundred thirty-seven thousand five hundred
(937,500) shares (subject to adjustment as provided herein) of Common Stock on the terms set forth below (collectively, including this Warrant, the Aggregate Warrants) in connection with the Debt Placement. Notwithstanding
that this Warrant was issued in connection with, and as part of, the Debt Placement, this Warrant is detachable from the Notes purchased in the Debt Placement and transferable separate from such Notes, but subject to the terms, conditions,
limitations and restrictions set forth in Section 5 of this Warrant.

|1. | Duration. The right to subscribe for and purchase shares of Common Stock represented hereby shall commence on the Original Issue Date, and
shall expire at 5:00 p.m., Chicago time, on May 28, 2015 (the Expiration Date); provided, that if the Expiration Date would otherwise occur on a day on which banking institutions are required or authorized by law to close in
Chicago, Illinois (a Bank Holiday), then the Expiration Date shall be the next succeeding day which shall not be a Bank Holiday. From and after the Expiration Date, this Warrant shall be null, void and of no further force or
effect.

Warrant in full in a cashless exercise, provided that the Company exercises such election with respect to all of the Aggregate Warrants then outstanding.



| | d) | In the event of any exercise of the rights represented by this Warrant in accordance with Section 2(a), (i) stock certificates for the
shares of Common Stock so purchased shall be delivered to the Holder, and, in the event the Warrant has not been exercised in full, a new Warrant representing the number of shares with respect to which this Warrant shall not then have been exercised

case such shares of Common Stock shall be registered in a name or names other than the Holder or its nominee, funds sufficient to pay all stock transfer taxes which shall be payable in connection with the execution and delivery of such stock
certificates shall be paid by the Holder to the Company at the time of the exercise of this Warrant.

| | e) | Notwithstanding any other provision hereof, if any exercise of any portion of this Warrant is made in connection with a registered public offering
or the sale of the Company (regardless of how structured), such exercise may be conditioned, at the election of the Holder, upon the consummation of such public offering or sale of the Company, in which case such exercise shall not be deemed to be
effective until immediately prior to the consummation of such transaction.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | f) | If a fractional share of Common Stock would be issuable upon exercise of this Warrant, the Company shall, as soon as reasonably practicable after
the date of exercise, deliver to the Holder a check payable to the Holder, in lieu of such fractional share, in an amount equal to the Market Value of such fractional share of Common Stock.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Adjustment of Warrant Price and Number of Shares.
|-- | -------------------------------------------------



| | a) | The Warrant Price and the number of shares of Common Stock purchasable upon the exercise of this Warrant shall be subject to adjustment from time to
time upon the happening of certain events occurring after the Original Issue Date, as follows:
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



| | i) | Reclassification, Consolidation or Merger. In case of any reclassification or change of outstanding Common Stock issuable upon exercise of
this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in case of any consolidation or merger of the Company with or into another
Company (other than a merger with another corporation in which the Company is the surviving corporation and which does not result in any reclassification or change other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination of outstanding Common Stock issuable upon such conversion) the rights of the holders of this Warrant shall be adjusted in the manner described below:
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (1) | In the event that the Company is the surviving corporation, the Warrant shall, without payment of additional consideration therefor, be deemed
modified so as to provide that upon exercise thereof the holder of this Warrant shall procure, in lieu of each share of Common Stock theretofore issuable upon such exercise, the kind and amount of shares of stock, other securities, money and
property receivable upon such reclassification, change, consolidation or merger by the holder of each share of Common Stock issuable upon such exercise had exercise occurred immediately prior to such reclassification, change, consolidation or
merger. This Warrant (as adjusted) shall be deemed to provide for further adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 3. The provisions of this clause (1) shall
similarly apply to successive reclassifications, changes, consolidations and mergers.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | In the event that the Company is not the surviving entity, the surviving entity shall, without payment of any additional consideration therefor,
issue new Warrants, providing that upon exercise thereof the holder thereof shall procure in lieu of each share of Common Stock theretofore issuable upon exercise of this Warrant the kind and amount of shares of stock, other securities, money and
property receivable upon such reclassification, change, consolidation or merger by the holder of each share of Common Stock issuable upon exercise of this Warrant had such exercise occurred immediately prior to such reclassification, change,
consolidation or merger. Such new Warrants shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 3. The provisions of this clause (2) shall similarly apply
to successive reclassifications, changes, consolidations and mergers. The Company shall not enter into any transaction subject to the provisions of this Section 3(a)(i)(2) unless the surviving entity in such transaction agrees in writing to
issue new Warrants in accordance with the terms and conditions of this Section 3(a)(i)(2) and comply with the terms and conditions of such new Warrants.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | Subdivision or Combination of Shares. If the Company, at any time while any of this Warrant is outstanding, shall subdivide or combine its
Common Stock, the Warrant
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | Price shall be proportionately reduced, in case of subdivision of shares, as of the effective date of such subdivision, or shall be proportionately increased, in the case of combination of
shares, as of the effective date of such combination. In the event that a record date is set with respect to any such subdivision, and this Warrant is exercised after such record date but prior to the effective date of such subdivision, upon the
effectiveness of such subdivision, the Company shall issue the Holder additional shares of Common Stock as if the Common Stock issued upon such exercise of the Warrant were outstanding on the record date with respect to such subdivision, without the
payment of any additional consideration.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii) | Certain Dividends and Distributions. If the Company, at any time while any of this Warrant is outstanding, shall:
| | ---- | -----------------------------------------------------------------------------------------------------------------



| | (1) | Stock Dividends. Pay a dividend payable in, or make any other distribution of Common Stock, the Warrant Price shall be adjusted, as of the
date of such payment or dividend or other distribution, to that price determined by multiplying the Warrant Price by a fraction (1) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such
dividend or distribution and (2) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution (plus in the event that the Company paid cash for fractional shares, the
number of additional shares which would have been outstanding had the Company issued such fractional shares in connection with such dividend or distribution); provided that in the event that a record date is set with respect to any such dividend and
distribution, and this Warrant is exercised after such record date but prior to the payment or other distribution of such dividend or other distribution, upon such payment or other distribution, the Company shall issue the Holder additional shares
of Common Stock as if the Common Stock issued upon such exercise of this Warrant were outstanding on the record date with respect to such dividend or other distribution, without the payment of any additional consideration.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (2) | Liquidating Dividends, etc. Make a distribution of its property to the holders of its Common Stock as a dividend in liquidation or partial
liquidation or by way of return of capital or other than as a dividend payable out of funds legally available for dividends under the laws of the State of Delaware, the holders of this Warrant shall, upon exercise hereof, be entitled to receive, in
addition to the number of shares of Common Stock receivable hereupon, and without payment of any consideration therefor, a sum equal to the amount of such property as would have been payable to them as owners of that number of shares of Common Stock
of the Company receivable upon such exercise, had they been the holders of record of such Common Stock on the record date for such distribution; and an appropriate provision therefor shall be made a part of any such distribution.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---



| | (3) | Purchase Rights. If at any time the Company grants, issues or sells any options, warrants, convertible securities or other rights to purchase
stock, warrants, options, securities or other property pro rata to the record holders of Common Stock (the Purchase Rights), then the Holder of this Warrant shall be entitled to acquire, upon the terms applicable to such Purchase
Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant immediately before the date on which a record is taken for the
grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iv) | Adjustment of Number of Shares. Upon each adjustment in the Warrant Price pursuant to any provision of this Section 3(a), the number of
shares of Common Stock issuable upon exercise hereof shall be adjusted, to the nearest one hundredth of a whole share, to the product obtained by multiplying the number of shares issuable upon exercise hereof immediately prior to such adjustment in
the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | Notice of Adjustments. Whenever any Warrant Price shall be adjusted pursuant to Section 3 hereof, the Company shall make a certificate
signed by its President or a Vice President and by its Treasurer, Assistant Treasurer, Secretary or Assistant Secretary, setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such
adjustment was calculated (including a description of the basis on which the Board made any determination hereunder), and the Warrant Price after giving effect to such adjustment, and shall cause copies of such certificate to be delivered by
first-class mail or postage prepaid) or by facsimile to the holder of this Warrant at its address or facsimile number shown on the books of the Company. The Company shall make such certificate and deliver it to each Holder promptly after each
adjustment.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | Default in Obligations Regarding Par Value. If the Company shall default in its obligation pursuant to the last sentence of Section 4(a)
hereof such that the par value per share of Common Stock would be greater than the Warrant Price that, absent the limitation contained in the last sentence of Section 4(a), would have been in effect pursuant to this Section 3, then the
Warrant Price shall be an amount equal to the par value per share of Common Stock but the number of shares the holder of this Warrant shall be entitled to purchase shall be such greater number of shares of Common Stock as would have resulted from
the Warrant Price that, absent the limitation contained in the last sentence of Section 4(a), would have been in effect pursuant to this Section 3. The foregoing adjustment shall not constitute a waiver of any claim arising against the
Company by reason of its default under the agreement contained in the last sentence of Section 4(a) of this Warrant.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|4. | Covenants.
|-- | ----------



| | a) | The Company covenants and agrees that all shares of Common Stock issued upon exercise of this Warrant will, upon issuance, be fully paid and
nonassessable and free from preemptive rights and any liens and charges with respect to the issuance thereof. The Company further covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, the
Company will at all times have authorized, and reserved for the purpose of issue upon exercise of the purchase rights evidenced by this Warrant, a sufficient number of shares of Common Stock to provide for the exercise in full of such purchase
rights (including any and all shares as to which the right to acquire such shares has not been forfeited pursuant to Section 1 hereof). Furthermore, and without limiting the generality of the foregoing, the Company covenants and agrees that it
will from time to time take all such action as may be required to assure that the par value per share of Common Stock is at all times equal to or less than the effective Warrant Price.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | The Company agrees that it shall not close its books against the transfer of this Warrant or of any shares of Common Stock issued or issuable upon
the exercise of this Warrant in any manner which interferes with the timely exercise of this Warrant.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | The Company shall cooperate with the Holder if the Holder is required to make any governmental filings or obtain any governmental approvals prior
to, or in connection with, the exercise of Warrants (including making any filings required to be made by the Company). The Company shall take all such actions as may be reasonably necessary to ensure that all shares of Common Stock issuable upon
exercise of the Warrants may be issued in accordance with the terms and conditions of the Warrants without violation of any applicable law or regulation of any governmental entity or self regulatory organization or any requirement of any securities
exchange or trading system on which the shares of Common Stock are listed or eligible for trading (except for official notice of issuance, which (to the extent required) shall be delivered immediately by the Company upon each such issuance).
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d) | If any securities issuable upon exercise of this Warrant are then convertible into or exchangeable for any other stock or securities of the Company
(Other Securities), the Company shall, at the Holders option and upon exercise of this Warrant by the Holder as provided herein, together with any notice, statement or payment required to effect such conversion or exchange,
deliver to the Holder (or such other Person specified by such Holder) a certificate or certificates representing the Other Securities into which the securities issuable upon such exercise of this Warrant are convertible or exchangeable, registered
in such name or names and in such denomination or denominations as the Holder has specified.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | e) | The Company shall not by any action, including, without limitation, amending its charter documents or through any reorganization, reclassification,
transfer of assets, consolidation, merger, dissolution, issue or sale of securities or other similar voluntary
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the rights of the Holder against impairment. Without limiting the foregoing, the Company shall take all action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant, free and clear of all mortgages, pledges, hypothecations, claims, charges, security interests, encumbrances, adverse claims, options,
liens, put or call rights, rights of first offer or refusal, proxies, voting rights or other restrictions or limitations of any nature whatsoever (collectively, Liens), other than Liens created by the actions of the Holder.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | f) | The Company shall provide each Holder with not less than 10 days prior written notice in the event that the Company closes its books or sets a
record date (i) with respect to either a dividend or distribution upon the Common Stock or a subscription offer to the holders of Common Stock or (ii) for determining rights to vote with respect to any merger, consolidation,
reorganization, restructuring or similar transaction (including, without limitation, the dissolution or liquidation of the Company). The Company shall also provide the Holder not less than 20 days prior written notice of the consummation of any such
transaction.

|5. | Transfer and Exchange.
|-- | ----------------------



| | a) | On and after the Original Issue Date, this Warrant shall be transferable with respect to all of the shares of Common Stock issuable upon exercise of
this Warrant. Any transfer of this Warrant shall be subject to the further terms, conditions, limitations and restrictions set forth in clauses (b) through (g) of this Section. For the avoidance of doubt, nothing in this Section 5(a)
shall prohibit or otherwise affect the right to transfer any shares of Common Stock received upon the exercise of this Warrant.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | The transfer of this Warrant and all rights hereunder, in whole or in part, is registrable at the office or agency of the Company referred to below
by the Holder, in person or by his duly authorized attorney, upon surrender of this Warrant properly endorsed. Each taker and holder of this Warrant, by taking or holding the same, consents and agrees that this Warrant, when endorsed in blank, shall
be deemed negotiable, and that the Holder, when this Warrant shall have been so endorsed, may be treated by the Company and all other Persons dealing with this Warrant as the absolute owner and holder hereof for any purpose and as the Person
entitled to exercise the rights represented by this Warrant, or to the registration of transfer hereof on the books of the Company; and until due presentment for registration of transfer on such books the Company may treat the Holder as the owner
and holder for all purposes, and the Company shall not be affected by notice to the contrary.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | The Holder of this Warrant, by the acceptance hereof, represents that it is acquiring this Warrant, and upon exercise hereof will acquire the
Warrant and the shares of Common
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | Stock issuable upon exercise hereof (collectively, including this Warrant, the Warrant Securities), for its own account and not with a view towards, or for resale in connection
with, the public sale or distribution of the Warrant Securities, except pursuant to sales registered or exempted under the Securities Act. The Holder further represents, by acceptance hereof, that, as of this date, such Holder is an accredited
investor as such term is defined in Rule 501(a)(3) of Regulation D promulgated by the Securities and Exchange Commission under the Securities Act (an Accredited Investor). The delivery of this Warrant for exercise shall
constitute confirmation at such time by the Holder of the representations concerning the Warrant Securities set forth in the first two sentences of this Section 5(c), unless contemporaneous with the delivery of this Warrant for exercise, the
Holder notifies the Company in writing that it is not making such representations (a Representation Notice). If the Holder delivers a Representation Notice in connection with an exercise, it shall be a condition to such
Holders exercise of this Warrant and the Companys obligations set forth in Section 2 in connection with such exercise, that the Company receive such other representations as the Company considers reasonably necessary to assure the
Company that the issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws, and the time periods for the Companys compliance with its obligations set forth in Section 2 shall be
tolled until such Holder provides the Company with such other representations.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d) | The Holder, by acceptance of this Warrant, understands that the Warrant Securities are characterized as restricted securities under the
federal securities laws inasmuch as they are being or will be acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations neither this Warrant nor the shares of Common Stock issuable
upon its exercise may be resold without registration under the Securities Act or under certain other limited circumstances. The Holder further agrees, by acceptance of this Warrant that it will not offer or sell this Warrant or any shares of Common
