Exhibit 10.11

WARRANT AGREEMENT (this Agreement), dated as of April 1, 2008 among Thornburg Mortgage, Inc., a Delaware corporation (the Company), the warrantholders listed on the signature pages hereto
(the Initial Holders) and each other Person (as defined in paragraph 7(a)) who subsequently becomes a party hereto.

NOW,
THEREFORE, the parties hereto hereby agree as follows:

1. Grant. The Company hereby grants to the Initial Holders warrants
designated as Class A warrants (Warrants) which shall entitle the registered holder thereof to purchase from the Company, at any time or from time to time after April 11, 2008 until 5:00 P.M., New York time, on April 1,
2013 (the Expiration Date), 46,960,000 shares (the Warrant Shares) of Common Stock, par value $0.01 per share, of the Company (Common Stock), at the exercise price of $0.01 per share (the Exercise
Price), all subject to the terms set forth herein. Each registered holder of Warrants agrees to exercise the Warrants as promptly as practicable after April 11, 2008 and from time to time thereafter to the extent permitted by applicable
federal, state and foreign laws and regulations.

2. Warrant Certificates. The Warrants shall be evidenced by certificates issued
pursuant to this Agreement (the Warrant Certificates) in the form set forth in Exhibit A hereto, with such appropriate insertions, omissions, substitutions, and other variations as are required or permitted by this Agreement.

3. Exercise of Warrant.

(a)
General. Subject to the provisions of this Agreement, upon surrender to the Company at its principal office of a Warrant Certificate with the annexed Form of Election to Purchase duly executed, together with payment in accordance with
paragraph 3(b) of the Exercise Price, and upon compliance with the requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (HSR) if applicable, the Company shall issue and deliver promptly to the registered
holder of such Warrant Certificate, a certificate or certificates for the Warrant Shares or other securities or property to which the registered holder is entitled, registered in the name of such registered holder or, upon the written order of such
registered holder, in such name or names as such registered holder may designate. In the case of an exercise of Warrants, any certificate or certificates representing Warrant Shares shall be deemed to have been issued to and any Person so designated
to be named therein shall be deemed to have become the holder of record of the Warrant Shares as of the date of the surrender of such Warrant Certificate (together with such duly executed Form of Election to Purchase) and payment of the Exercise
Price. Each Warrant not exercised or deemed exercised on or prior to the Expiration Date shall become invalid and all rights thereunder, and all rights in respect thereof under this Agreement, shall cease as of that time.

(b) Payment. Payment of the Exercise Price shall be made, at the option of the registered holder of the Warrants, (i) in cash, by certified
check or wire transfer payable to the order of the Company, (ii) on a net basis, such that without the exchange of any funds, such holder receives that number of Warrant Shares that would otherwise be issuable upon a cash exercise of such
Warrants less that number of Warrant Shares having a current market price (as defined in paragraph 6(d)) equal to the aggregate Exercise Price that would otherwise have been



1



---

paid by such holder for the number of Warrant Shares with respect to which such Warrant is being exercised in which case, such exchange shall be treated as a
recapitalization under Section 368(a) of the Internal Revenue Code of 1986, as amended (the Code), or (iii) by any combination of the foregoing.

(c) Exercise in Whole or in Part. The purchase rights evidenced by a Warrant Certificate shall be exercisable, at the election of the registered holder thereof, in whole or in part, but only for lots of 100
Warrant Shares or integral multiples thereof if less than all the Warrants then held by such registered holder are being exercised. If less than all of the Warrant Shares purchasable under any Warrant Certificate are purchased, the Company shall
cancel such Warrant Certificate upon the surrender thereof and shall execute and deliver a new Warrant Certificate of like tenor for the remaining number of Warrant Shares purchasable thereunder.

(d) Fractional Shares. No fractional shares of Common Stock shall be issued upon exercise of any Warrants. Instead the Company shall round the
results of an exercise up to the nearest full share of Common Stock.

(e) Reservation of Shares. The Company will at all times
reserve and keep available out of its authorized Common Stock solely for the purpose of issuance upon exercise of the Warrants as herein provided, such number of shares of Common Stock as shall from time to time be issuable upon the exercise of all
outstanding Warrants. All shares of Common Stock that may be issued upon exercise of the Warrants will, upon issuance, be validly issued, fully paid and nonassessable and not subject to preemptive rights of any shareholder.

4. Transfer.

(a) Warrant
Register. The Company shall maintain at its principal office a Warrant Register for registration of Warrant Certificates and transfers thereof. The Company shall initially register the outstanding Warrants in the name of each Initial Holder. The
Company may deem and treat the registered holder(s) of the Warrant Certificates as the absolute owner(s) thereof and of the Warrants represented thereby (notwithstanding any notation of ownership or other writing on the Warrant Certificates made by
any Person) for the purpose of any exercise thereof or any distribution to the holder(s) thereof, and for all other purposes, and the Company shall not be affected by any notice to the contrary. For the purpose of this Agreement, all references to a
holder herein shall refer to a registered holder of Warrants.

(b) Warrants and Warrant Shares Not Registered. Each registered
holder of the Warrants, by acceptance thereof, represents and acknowledges that the Warrants and the Warrant Shares which may be purchased upon exercise of a Warrant are not registered under the Securities Act of 1933, as amended (the
Securities Act), that the issuance of the Warrants and the offering and sale of such Warrant Shares are being made in reliance on the exemption from registration under Section 4(2) of the Securities Act as not involving any public
offering and that the Companys reliance on such exemption is predicated in part on the representations made by each Initial Holder of the Warrants to and with the Company that such holder (1) is acquiring the Warrants for investment for
its own account, with no present intention of reselling or otherwise distributing the same, (2) is an accredited investor as defined in Regulation D under the Securities Act, and (3) has such knowledge and experience in
financial and business matters that



2



---

it is capable of evaluating the merits and risks of the investments made or to be made in connection with the acquisition and exercise of the Warrants.
Neither the Warrants nor the related Warrant Shares may be transferred except (i) pursuant to an effective registration statement under the Securities Act, (ii) pursuant to Rule 144 under the Securities Act if the transferor delivers a
certificate, in form and substance reasonably satisfactory to the Company, that such transfer complies with the requirements of Rule 144, or (iii) pursuant to any other available exemption from registration if such transferee makes the
representations set forth in the preceding sentence in writing to the Company. The Company reserves the right to restrict any offer, sale or other transfer of Warrants or Warrant Shares pursuant to clause (iii) above and to require the
completion, execution and delivery of (x) a letter from the transferee substantially in the form of the Transferees Letter attached hereto as Exhibit B and (y) an opinion of counsel satisfactory to the Company that the proposed
transfer does not require registration under the Securities Act, which opinion shall be at the expense of the Company.

(c) Notice and
Registration of Transfer. Each registered holder of the Warrants, by acceptance thereof, agrees that prior to any disposition by such holder of the Warrants or of any Warrant Shares, such holder will give written notice to the Company expressing
such holders intention to effect such disposition and describing briefly such holders intention as to the manner in which the Warrants or the Warrant Shares theretofore issued or thereafter issuable upon exercise hereof, are to be
disposed of, whereupon, but only if such transfer is permitted pursuant to paragraph 4(b) above, such transferring holder shall be entitled to dispose of the Warrants and/or the Warrant Shares theretofore issued upon the exercise thereof, all in
accordance with the terms of the notice delivered by such holder to the Company. In the event of such transfer, the Company shall register the transfer of any outstanding Warrants in the Warrant Register upon surrender of the Warrant Certificate(s)
evidencing such Warrants to the Company at its principal office, accompanied by a written instrument of transfer in form reasonably satisfactory to it, duly executed by the registered holder thereof. Upon any such registration or transfer, new
Warrant Certificate(s) evidencing such transferred Warrants shall be issued to the transferee(s) and the surrendered Warrant Certificate(s) shall be canceled.

5. Special Agreements of the Company. The Company covenants and agrees as follows:

(a) Listing
on Securities Exchanges. If the Common Stock is listed on a stock exchange, the Company will use its best efforts to procure at its sole expense the listing of all Warrant Shares (subject to issuance or notice of issuance) on all stock exchanges
on which the Common Stock is then listed, and maintain the listing or quotation of such shares and other securities after issuance.

(b)
Actions in Avoidance. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, issue or sale of securities or otherwise, avoid or take any action which
would have the effect of avoiding the observance or performance of any of the terms to be observed or performed hereunder by the Company but will at all times in good faith assist in carrying out all of the provisions of the Warrants and in taking
all of such action as may be necessary or appropriate in order to protect the rights of the registered holders of the Warrants against impairment. Without limiting the generality of the foregoing, the Company will (i) take all such



3



---

action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the
exercise of the Warrants, and (ii) use its reasonable best efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Agreement.

6. Adjustment of Number of Warrant Shares Issuable. The number and kind of shares purchasable
upon the exercise of Warrants shall be subject to adjustment from time to time as follows:

(a) In case the Company shall, while this
Agreement remains in effect, (i) declare a dividend or make a distribution on its Common Stock payable in shares of its capital stock (whether shares of Common Stock or of capital stock of any other class), (ii) subdivide shares of its
Common Stock into a greater number of shares, (iii) combine its outstanding Common Stock into a smaller number of shares, or (iv) issue any shares of its capital stock by reclassification of its Common Stock (including any such
reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), the holder of each Warrant shall be entitled to purchase the aggregate number and kind of Warrant Shares which, if such Warrant had
been exercised immediately prior to such event, such Holder would have owned upon such exercise and been entitled to receive by virtue of such dividend, distribution, subdivision, combination or reclassification. Such adjustment shall be made
successively whenever any event listed above shall occur.

(b) In case the Company shall, while this Agreement remains in effect,
(i) issue any Common Stock (excluding issuances upon exercise of Warrants, upon exercise of the Class B Warrants to purchase 197,929,427 shares of Common Stock issued to the investors identified on that certain warrant agreement dated
March 28, 2008 among the Company and the investors listed on the signature page thereto (the Investor Warrant Agreement), upon exercise of any other Class B Warrants issued pursuant to the Investor Warrant Agreement (the
Additional Warrants) or upon exercise of the warrants or alternative consideration to be issued to the holders of shares of preferred stock of the Company in the self-tenders contemplated by the Term Sheet, dated March 24, 2008,
among Thornburg Mortgage, Inc., MatlinPatterson Global Opportunities Partners III L.P., MatlinPatterson Global Opportunities Partners (Cayman) III L.P. and Thornburg Mortgage Advisory Corporation (collectively, including consent solicitations to
delete restrictive covenants, including without limitation voting and dividend blocker provisions in the Articles Supplementary for such series of preferred stock, the Tender Offer)) at a price per share less than current market price
per share of Common Stock on the date of such issuance or (ii) issue any rights, warrants (other than in connection with this Agreement or the Tender Offer), options or other securities exercisable or exchangeable for or convertible into Common
Stock at an equivalent price per share less than the current market price per share of Common Stock on the date of such issuance, the number of Warrant Shares that are purchasable hereunder after such issuance shall be determined by multiplying the
number of Warrant Shares purchasable hereunder immediately prior to the date of issuance by a fraction, the denominator of which shall be the number of shares of Common Stock outstanding on such date plus the number of shares of Common Stock that
the aggregate price of the total number of shares so issued or offered for subscription or purchase would purchase at such current market price, and the numerator of which shall be the number of shares of Common



4



---

Stock outstanding on such date plus the number of additional shares of Common Stock or rights to acquire Common Stock issued or offered for subscription or
purchase (or into which the convertible securities so offered are convertible). Shares of Common Stock owned by or held for the account of the Company or any subsidiary on such date shall not be deemed outstanding for the purpose of any such
computation. Such adjustment shall become effective immediately after such issuance. Such adjustment shall be made successively whenever any such event shall occur. No further adjustment shall be made upon the conversion, exercise or exchange of
such security if any adjustment shall have been made upon the issuance of such security.

(c) In case the Company shall, while this
Agreement remains in effect, fix a record date for the making of a distribution to all holders of its Common Stock (including any such distribution to be made in connection with a consolidation or merger in which the Company is to be the continuing
corporation) of evidences of its indebtedness or shares of any class of capital stock, cash or other property or assets (excluding dividends paid in or distributions of the Companys capital stock for which the number of Warrant Shares
purchasable hereunder shall have been adjusted pursuant to paragraph 6(a)) or subscription rights or warrants (excluding those referred to in paragraph 6(b)) the number of Warrant Shares that are purchasable hereunder after such record date shall be
determined by multiplying the number of Warrant Shares that are purchasable hereunder immediately prior to such record date by a fraction, of which the denominator shall be the current market price per share of Common Stock on such record date, less
the fair market value (which for the avoidance of doubt when calculating fair market value shall take into consideration the consideration, if any, paid or to be paid by the holders of Common Stock for such distribution) as determined in good faith
by the Board of Directors of the Company (the Board), consistent with Section 6(d) and Section 6(e) below, of the portion of the assets or evidences of indebtedness so to be distributed to a holder of one share of Common Stock
or of such subscription rights or warrants applicable to one share of Common Stock, and the numerator shall be such current market price per share of Common Stock on such record date. Such adjustment shall become effective immediately after such
record date. Such adjustment shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the number of Warrant Shares that are Common Stock purchasable hereunder shall again be adjusted to
be the number that was in effect immediately prior to such record date.

(d) For the purpose of any computation under this Agreement, the
current market price per share of Common Stock on any day shall be:

(A) if the Common Stock is listed or admitted to
trading on a principal national securities exchange in the United States or in the over-the-counter market, the current market price per share shall be deemed to be the average of the Closing Prices of the Common Stock for the 10 consecutive trading
days immediately preceding the trading day before the earlier of (x) the day in question and (y) the date on which the relevant adjustment event is publicly announced; provided that, in the case of paragraph 6(c), if the period
between the date of the public announcement of the dividend or distribution and the date for the determination of holders of Common Stock entitled to receive such dividend or distribution



5



---

shall be less than 10 trading days, the period shall be such lesser number of trading days but, in any event, not less than five trading days;

(B) if the Common Stock is not quoted or listed by any such organization, exchange or market, the current market price per share shall be
the fair market value thereof as determined in good faith by the Board. If a registered holder of a Warrant Certificate shall object to any determination by the Board of such current market price per share, the current market price per share shall
be the fair market value per share of the Common Stock as determined by an independent appraiser retained by the Company at its expense and reasonably acceptable to such registered holder.

(e) For purposes of any computation respecting consideration received pursuant to paragraph 6(c) above, the following shall apply:

(A) in the case of the issuance of shares of Common Stock for cash, the consideration shall be the gross proceeds to the Company from
such issuance, which shall not include any deductions for any commissions, discounts or other expenses incurred by the Company in connection therewith;

(B) in the case of the issuance of shares of Common Stock for a consideration in whole or in part other than cash or, subject to clause (C), securities, the consideration other than cash shall be deemed to be the fair
market value thereof as determined in good faith by the Board (irrespective of the accounting treatment thereof). If a registered holder of a Warrant Certificate shall object to any determination by the Board of the fair market value of such
consideration other than cash, the consideration shall be deemed to be the fair market value of such consideration as determined by an independent appraiser retained by the Company at its expense and reasonably acceptable to such registered holder;

(C) in the case of the issuance of shares of Common Stock for a consideration in whole or in part consisting of
securities, the value of any securities shall be deemed to be: (x) if traded on a securities exchange, the average of the closing prices of the securities on such securities exchange or quotation system over the 10 trading day period ending on
the trading day immediately preceding the day in question, (y) if actively traded over-the-counter, the average of the closing bid or sale prices (whichever is applicable) over the 10 day period ending on the trading day immediately preceding
the day in question and (z) if there is no active public market, the fair market value thereof, determined as provided in clause (B) above; and

(D) in the case of the issuance of securities convertible into, exercisable for or exchangeable for shares of Common Stock, the



6



---

aggregate consideration received therefor shall be deemed to be the consideration received by the Company for the issuance of such securities plus the
additional consideration, if any, to be received by the Company upon the conversion, exercise or exchange thereof (the consideration in each case to be determined in the same manner as provided in clauses (A) through (C) of this paragraph
6(i)).

(f) No adjustment in the number of Warrant Shares need be made until all cumulative adjustments amount to an increase or decrease
of at least one whole share. All calculations under this paragraph 6 shall be made to the nearest 1/1,000th of a share.

(g) For purposes
of this paragraph 6, Common Stock includes any stock of any class of the Company which has no preference in respect of dividends or of amounts payable in the event of any voluntary or involuntary liquidation, dissolution or winding-up of
the Company and which is not subject to redemption by the Company. However, subject to the provisions of paragraph 6(j) below, shares issuable on exercise of the Warrants shall include only shares of the class designated as Common Stock of the
Company on the date hereof or shares of any class or classes resulting from any reclassification thereof and which have no preferences in respect of dividends or amounts payable in the event of any voluntary or involuntary liquidation, dissolution
or winding-up of the Company and which are not subject to redemption by the Company and which retain all the voting rights of the Common Stock of the Company on the date hereof (but not necessarily the percentage of such voting rights in the total
Common Stock); provided that, if at any time there shall be more than one such resulting class, the shares of each such class then so issuable shall be substantially in the proportion which the total number of shares of such class resulting
from all such reclassifications bears to the total number of shares of all such classes resulting from all such reclassifications.

(h) The
Company hereby agrees with each holder of Warrants that it shall not increase the par value of the Common Stock above its current par value of $0.01 per share. No adjustment in the number of Warrant Shares need be made under paragraphs 6(a), 6(b) or
6(c) above if the Company issues or distributes to each registered holder of Warrants the shares of Common Stock, evidences of indebtedness, assets or other property, rights or securities referred to in those paragraphs which each such registered
holder would have been entitled to receive had the Warrants been exercised prior to the happening of such event or the record date with respect thereto.

(i) Whenever the number of Warrant Shares purchasable upon exercise of any Warrant shall be adjusted, the Company shall promptly mail to registered holders of Warrants, first class, postage prepaid, a notice of the
adjustment together with a certificate from the Companys chief financial officer briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence that the adjustment is correct.

(j) If:



7



---

(A) the Company takes any action which would require an adjustment in the number of
Warrant Shares purchasable upon exercise of any Warrant pursuant to this paragraph 6;

(B) the Company consolidates or
merges with, or transfers all or substantially all of its assets to, another corporation, and shareholders of the Company must approve the transaction; or

(C) there is a dissolution or liquidation of the Company;

the Company shall mail to registered holders of the Warrants,
first class, postage prepaid, a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice at least 5 days before such proposed record or effective date. However, failure to mail the notice or any
defect in it shall not affect the validity of any transaction referred to in clause (A), (B) or (C) of this paragraph 6(i).

(k)
In the case of any consolidation of the Company or the merger of the Company with or into any other entity or the sale or transfer of all or substantially all the assets of the Company pursuant to which the Companys Common Stock is converted
into other securities, cash or assets or other property, upon consummation of such transaction, each Warrant shall automatically thereafter become exercisable for the kind and amount of securities, cash or other assets or other property receivable
upon the consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock into which such Warrant might have been converted immediately prior to such consolidation, merger, transfer or sale (assuming such holder of Common
Stock failed to exercise any rights of election and received per share the kind and amount of consideration receivable per share by a plurality of non-electing shares). Appropriate adjustment (as determined by the Board) shall be made in the
application of the provisions herein set forth with respect to the rights and interests thereafter of the holders of Warrants, to the end that the provisions set forth herein (including provisions with respect to changes in and other adjustment of
the number of shares of Common Stock issuable upon the exercise of the Warrants) shall thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other securities or assets or property thereafter deliverable upon
the exercise of Warrants. If this paragraph 6(k) applies to any transaction, paragraph 6(a) does not apply to such transaction.

(l) In any
case in which this paragraph 6 shall require that an adjustment as a result of any event becoming effective from and after a record date, the Company may elect to defer until after the occurrence of such event the issuance to the holder of any
Warrants exercised after such record date and before the occurrence of such event of the additional shares of Common Stock issuable upon such conversion over and above the shares issuable on the basis of the number of Warrant Shares in effect
immediately prior to adjustment; provided, however, that if such event shall not have occurred and authorization of such event shall be rescinded by the Company, the number of Warrant Shares shall be recomputed immediately upon such
recession, to the price that would have been in effect had such event not been authorized, provided that such recission is permitted by and effective under applicable laws; provided further, that if such Event has not occurred within 60 days
following the exercise of the Warrants, the issuance of such additional shares shall in any event be made not later than on the



8



---

61stday following exercise of the Warrant as if such
event occurred on the 60thday. For the avoidance of doubt, such distribution on the 61stday shall not prejudice the holder of any Warrant against receiving any additional shares of Common Stock (above the shares that they received on such 61stday) that they would be entitled to if they had not received any shares on the 61stday and the event occurs on or after such 61stday.

(m) If any event occurs as to which the foregoing provisions of this paragraph 6 are not strictly applicable or, if strictly applicable, would not, in the good faith judgment of the Board, fairly and adequately
protect the purchase rights of the Warrants in accordance with the essential intent and principles of such provisions, then the Board shall make such adjustments in the application of such provisions, in accordance with such essential intent and
principles, as shall be reasonably necessary, in the good faith opinion of the Board, to protect such purchase rights as aforesaid.

(b) Incidental Registration. (i) If the Company at any time after the date hereof proposes to
register equity securities under the Securities Act (other than a registration on Form S-4 or S-8, or any successor or other forms promulgated for similar purposes), whether or not for sale for its own account, it will, at each such time, give
prompt written notice to all registered holders of the Warrants of its intention to do so and of such registered holders rights under this paragraph 7. Upon the written request of any such registered holder made within fifteen (15) days
after the receipt of any such notice (which request shall specify the Registrable Securities intended to be disposed of by such registered holder), the Company will use its best efforts to effect the registration under the Securities Act of all
Registrable Securities that the Company has been so requested to register by the registered holders thereof; provided that:

(A) if, at any time after giving written notice of its intention to register any securities, the Company shall determine for any reason not to proceed with the proposed registration of the securities to be sold by it, the Company may, at
its election, give written notice of such determination to each registered holder of Registerable Securities and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not
from its obligation to pay the registration expenses already incurred in connection therewith), and

(B) if such
registration involves an underwritten offering, all registered holders of Registerable Securities requesting to be included in the Companys registration must sell their Registrable Securities to the underwriters selected by the Company on the
same terms and conditions as apply to the Company, with such differences, including any with respect to indemnification and liability insurance, as may be customary or appropriate in combined primary and secondary offerings.

(ii) If a registration requested pursuant to this paragraph 7 involves an underwritten public offering, any registered holder of
Registerable Securities requesting to be included in such registration may elect, in writing prior to the effective date of the registration statement filed in connection with such registration, not to register all or any part of such securities in
connection with such registration. Nothing in this paragraph 7 shall operate to limit the right of any registered holder of Registerable Securities to request the registration of Common Stock issuable upon the conversion, exchange or exercise of the
Warrants or any other securities held by such registered holder notwithstanding the fact that at the time of request such registered holder does not hold the Common Stock underlying such securities. The registrations provided for in this paragraph
7(b) are in addition to, and not in lieu of, registrations made upon the request of the registered holders of Registerable Securities in accordance with paragraph 7(c) and paragraph 7(d).

(iii) The Company will pay all Registration Expenses in connection with each registration of Registrable Securities requested pursuant to
this paragraph 7(b).

(iv) If a registration pursuant to this paragraph 7(b) involves an underwritten offering and the
managing underwriter advises the Company in writing that,



11



---

in its opinion, the number of Registrable Securities requested to be included in such registration would be likely to have an adverse effect on the price,
timing or distribution of the securities to be offered in such offering as contemplated by the Company (other than the Registrable Securities), then the Company shall include in such registration (i) first, 100% of the securities the Company
proposes to sell for its own account, and (ii) second, to the extent of the amount of Registrable Securities requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without having the
adverse effect referred to above, the amount of Registrable Securities which the registered holders of Registerable Securities have requested to be included in such registration, such amount to be allocated pro rata among all requesting registered
holders of Registerable Securities on the basis of the relative amount of Registrable Securities then held by each such registered holder (provided that any such amount thereby allocated to any such registered holder that exceeds such
registered holders request shall be reallocated among the remaining requesting registered holders of Registerable Securities in like manner).

(c) Registration on Request. (i) At any time or from time to time following the date hereof, upon the written request of any registered holder or holders of Registerable Securities (such holder or holders, the Demand
Party), requesting that the Company effect the registration under the Securities Act of all or part of such Demand Partys Registrable Securities and specifying the amount and intended method of disposition thereof, the Company will
promptly give written notice of such requested registration to all registered holders of Registerable Securities other than the Demand Party, and thereupon will, as expeditiously as possible, use its best efforts to effect the registration under the
Securities Act of (A) the Registrable Securities which the Company has been so requested to register by the Demand Party and (B) all other Registrable Securities of the same class or series as are to be registered at the request of the
Demand Party and which the Company has been requested to register by any other registered holder thereof by written request given to the Company within fifteen (15) days after the giving of such written notice by the Company (which request
shall specify the amount and intended method of disposition of such Registrable Securities), all to the extent necessary to permit the disposition (in accordance with the intended method thereof as aforesaid) of the Registrable Securities so to be
registered; provided that the Company shall not be required to effect any registration to be effected pursuant to this paragraph 7(c) unless at least 10% of the Registrable Securities outstanding at the time of such request is to be included
in such registration; and provided, further, that if the Company shall have previously effected a registration pursuant to this paragraph 7(c) or paragraph 7(d) (with respect to all such Registrable Securities) or shall have previously
effected a registration of which notice has been given to the Holders pursuant to paragraph 7(b) hereof, the Company shall not be required to effect any registration pursuant to this paragraph 7(c) until a period of 180 days shall have elapsed from
the date on which the previous such registration ceased to be effective.

(ii) The Company shall select the registration
statement form for any registration pursuant to this paragraph 7(c); provided that if any registration requested pursuant to this paragraph 7(c) that is proposed by the Company to be effected by the filing of a registration statement on Form
S-3 (or any successor or similar short-form registration statement) is in connection with an underwritten public offering, and if the managing underwriter advises the Company in writing that, in its opinion, the use of



12



---

another form of registration statement is of material importance to the success of such proposed offering, then such registration shall be effected on such
other form.

(iii) The Company will pay all registration expenses in connection with registrations of each class or series
of Registrable Securities pursuant to this paragraph 7(c).

(iv) A registration requested pursuant to this paragraph 7(c)
will not be deemed to have been effected unless it has become effective and all of the Registrable Securities registered thereunder have been sold.

(v) If a requested registration pursuant to this paragraph 7(c) involves an underwritten offering, the investment banker(s), underwriter(s) and manager(s) for such registration shall be selected by the registered
holders of a majority of the Registrable Securities that the Company has been requested to register; provided that if one or more Initial Holders is a Demand Party, then such Initial Holder(s) shall select the investment banker(s),
underwriter(s) and manager(s) for such registration; and provided further that such investment banker(s), underwriter(s) and manager(s) shall in any case be reasonably satisfactory to the Company.

(vi) If a requested registration pursuant to this paragraph 7(c) involves an underwritten offering and the managing underwriter advises
the Company in writing that, in its opinion, the number of securities to be included in such registration (including securities of the Company which are not Registrable Securities) would be likely to have an adverse effect on the price, timing or
distribution of the securities to be offered in such offering as contemplated by the registered holders of Registerable Securities (an Adverse Effect), then the Company shall include in such registration (i) first, 100% of
the Registrable Securities requested to be included in such registration by the Demand Party and all other registered holders of Registrable Securities pursuant to this paragraph 7(c) (to the extent that the managing underwriter, if applicable,
believes that all such Registrable Securities can be sold in such offering without having an Adverse Effect; provided that if they cannot and the Demand Party does not exercise its right set forth in the next sentence of this clause (vi),
such lesser number of Registrable Securities the managing underwriter believes can be sold in the offering without having an Adverse Effect allocated pro rata among the Demand Party and all requesting other registered holders of Registerable
Securities on the basis of the amount of Registrable Securities requested to be included in such registration (provided that any such amount thereby allocated to any such Demand Party or registered holder of Registerable Securities that
exceeds its request shall be reallocated among the remaining Demand Party and requesting registered holders of Registerable Securities in a like manner)), (ii) second, to the extent the managing underwriter believes additional securities can be
sold in the offering without having an Adverse Effect, the amount of equity securities of the Company that the Company intends to sell for its own account, and (iii) third, to the extent the managing underwriter believes additional securities
can be sold in the offering without having an Adverse Effect, the amount of Other Securities requested to be included by Other Holders in such registration, allocated pro rata among all requesting Other Holders on the basis of the relative amount of
all Other Securities then held by



13



---

each such Other Holder (provided that any such amount thereby allocated to any such Other Holder that exceeds such Other Holders request shall
be reallocated among the remaining requesting Other Holders in a like manner). If the managing underwriter of any underwritten offering shall advise the registered holders of Registerable Securities participating in a registration pursuant to this
paragraph 7(c) that the Registrable Securities covered by the registration statement cannot be sold in such offering within a price range acceptable to the Demand Party, then the Demand Party shall have the right to notify the Company that it has
determined that the registration statement be abandoned or withdrawn, in which event the Company shall abandon or withdraw such registration statement.

(vii) Notwithstanding paragraph 7(c)(vi), (x) if the Board determines, in its good faith judgment, that the registration and offering otherwise required by this paragraph 7(c) would have an Adverse Effect on a
then-contemplated public offering of the Companys equity securities, the Company may postpone the filing (but not the preparation) of a registration statement required by this paragraph 7(c), during the period starting with the 30th day
immediately preceding the date of the anticipated filing of, and ending on a date 60 days following the effective date of, the registration statement relating to such other public offering and (y) if the Company shall furnish to the registered
holders of Registerable Securities a certificate signed by its chairman of the Board, chief executive officer, president or any other of its authorized officers stating that the Company has pending or in process a material transaction, the
disclosure of which would, in the good faith judgment of the Board, after consultation with its outside securities counsel, materially and adversely affect the Company, the Company may postpone the filing (but not the preparation) of a registration
statement required by this paragraph 7(c) until the earlier of (A) 90 days from the date of such certificate or (B) the date on which such certificate ceases to be accurate; provided that the Company shall at all times in good faith
use its best efforts to cause any registration statement required by this paragraph 7(c) to be filed as soon as possible and; provided further that, the Company shall not be permitted to postpone registration pursuant to this paragraph
7(c)(vii) more than once in any 180-day period. The Company shall promptly give the registered holders of Registerable Securities requesting registration thereof pursuant to this paragraph 7(c) written notice of any postponement made in accordance
with the preceding sentence. If the Company gives the registered holders of Registerable Securities such a notice, the registered holders of Registerable Securities shall have the right, within 15 days after receipt thereof, to withdraw their
request in which case, such request will not be counted for purposes of this paragraph 7(c).

(d) Shelf Registration.

(i) At any time or from time to time following the date hereof, upon the written request of any registered holder or holders of
Registerable Securities, the Company shall promptly give written notice of such requested registration to all registered holders of Registerable Securities other than the requesting holder(s), and the Company shall as promptly as practicable file
with the Securities and Exchange Commission (the SEC) a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Securities (the



14



---

Shelf Registration Statement) (A) so requested to be registered and (B) all other Registrable Securities of the same class or
series as those referenced in clause (A) that the Company has been requested to register by any other registered holder thereof by written request given to the Company within fifteen (15) days after the giving of such written notice by the
Company (which request shall specify the amount and intended method of disposition of such Registrable Securities);provided that the Company shall not be required to effect any registration to be effected pursuant to this paragraph 7(d)
unless at least 10% of the Registrable Securities outstanding at the time of such request are to be included in such registration. The Shelf Registration Statement shall permit registration of such Registrable Securities for resale in the United
States by registered holders in the manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Company shall not permit any securities other than the Registrable Securities to be included in the
Shelf Registration Statement or any Subsequent Shelf Registration Statement (as defined below). The Company shall use its best efforts to cause the initial Shelf Registration Statement to be declared effective by the SEC under the Securities Act by
the 180th day after the registered holders of Registrable Securities requested the Shelf Registration Statement and to keep the Shelf Registration Statement continuously effective under the Securities Act until the first anniversary of its effective
date, subject to extension pursuant to clause (iv) of this paragraph 7(d) (the Effectiveness Period), or such shorter period ending when (i) all Registrable Securities covered by the Shelf Registration Statement have
been sold in the manner set forth and as contemplated in the initial Shelf Registration Statement or (ii) a Subsequent Shelf Registration Statement covering all of the Registrable Securities has been declared effective under the Securities Act.
Notwithstanding any other provision hereof, no holders Registrable Securities shall be included in the Shelf Registration Statement unless and until such holder furnishes to the Company in writing such information as the Company may reasonably
request in writing for use in connection with the Shelf Registration Statement and any related application to be filed with or under state securities laws.

(ii) If the initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at
any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Company shall use its best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and
in any event shall within 7 days of such cessation of effectiveness amend the Shelf Registration Statement in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional shelf Registration
Statement pursuant to Rule 415 covering all of the Registrable Securities (a Subsequent Shelf Registration Statement) to permit registration of the Registrable Securities for resale in the United States. If a Subsequent Shelf
Registration Statement is filed, the Company shall use its best efforts to cause the Subsequent Shelf Registration to be declared effective under the relevant Securities Laws as soon as practicable after such filing and to keep such Registration
Statement continuously effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Shelf Registration Statement or any Subsequent Shelf Registration Statement was previously
continuously effective.



15



---

As used herein the term Shelf Registration Statement means the Shelf Registration Statement and any Subsequent Shelf Registration
Statement.

(iii) The Company shall promptly supplement and amend the Shelf Registration Statement if required by the
rules, regulations or instructions applicable to the registration form used for such Shelf Registration Statement, if required by the Securities Act, or if reasonably requested by the registered holders of the Registrable Securities then outstanding
or by any underwriter of such Registrable Securities.

(iv) At any time while the Shelf Registration Statement is effective
and a prospectus relating thereto is required to be delivered under the Securities Act within the Effectiveness Period, that the Company becomes aware that the Shelf Registration Statement or any prospectus included therein, as then in effect,
includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, to the extent that the
amendment or supplement to such Shelf Registration Statement or prospectus necessary to correct such untrue statement of a material fact or omission to state a material fact would require disclosure of material information which the Company has a
bona fide business purpose for preserving as confidential and the Company provides the registered holders of Registerable Securities written notice thereof promptly after the Company makes such determination, the registered holders of Registerable
Securities shall suspend sales of Registrable Securities pursuant to the Shelf Registration Statement and the Company shall not be required to comply with its obligations under paragraph 7(e)(i)) until the earlier of (A) the date upon which
such material information is disclosed to the public or ceases to be material or (B) 90 days after receipt of such written notice by the registered holders of Registerable Securities. If the registered holders disposition of Registrable
Securities is discontinued pursuant to the foregoing sentence, the Effectiveness Period shall be extended by the number of days during the period from and including the date of the giving of such notice and including the date when each seller of
Registrable Securities covered by the Shelf Registration Statement shall have received copies of the supplemented or amended prospectus contemplated by clause (v) of paragraph 7(e).

(v) The Company will pay all Registration Expenses in connection with the registration of Registrable Securities pursuant to this
paragraph 7(d).

(vi) If a requested registration pursuant to this paragraph 7(d) includes an underwritten offering, the
investment banker(s), underwriter(s) and manager(s) for such offering shall be selected by the registered holders of a majority of the Registrable Securities to be registered thereunder; provided however that such investment banker(s),
underwriter(s) and manager(s) shall be reasonably satisfactory to the Company.

(e) Registration Procedures. If and whenever the
Company is required to use its best efforts to effect or cause the registration of any Registrable Securities under the Securities Act as provided in this Agreement, the Company will promptly:



16



---

(i) prepare and, in any event within 30 days after the end of the period within which a
request for registration may be given to the Company, file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective within 90 days of the
initial filing (and, in the case of the initial Shelf Registration, effective no later than 180 days after date hereof);

(ii) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period not in excess

disposition by the seller or sellers thereof set forth in such registration statement; provided that before filing a registration statement or prospectus, or any amendments or supplements thereto in accordance with paragraphs 7(e)(i) or (ii),
the Company will furnish to counsel selected pursuant to paragraph 7(j) hereof copies of all documents proposed to be filed, which documents will be subject to the review of such counsel and the Company shall not file any such document to which the
Demand Party objects;

(iii) furnish to each seller of such Registrable Securities such number of copies of such
registration statement and of each amendment and supplement thereto (in each case including all exhibits filed therewith, including any documents incorporated by reference), such number of copies of the prospectus included in such registration

reasonably request in order to facilitate the disposition of the Registrable Securities by such seller in accordance with such Sellers intended method of disposition;

(iv) use its best efforts to register or qualify such Registrable Securities covered by such registration in such jurisdictions as each
seller shall reasonably request, and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Securities owned by such seller,
except that the Company shall not for any such purpose be required to qualify generally to do business as a foreign corporation in any jurisdiction where, but for the requirements of this subparagraph (iv), it would not be obligated to be so
qualified, to subject itself to taxation in any such jurisdiction or to consent to general service of process in any such jurisdiction;

includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and prepare and furnish to
such seller a reasonable number of copies of an amended or supplemental prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing;

(vii) otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security
holders, as soon as reasonably practicable (but not more than 18 months) after the effective date of the registration statement, an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act;

(viii) use its best efforts to list Registrable Securities on any securities exchange or quotation service on which the Common Stock is
then listed if such Registrable Securities are not already so listed and if such listing is then permitted under the rules of such exchange or service; and (ii) use its best efforts to provide a transfer agent and registrar for such Registrable
Securities covered by such registration statement not later than the effective date of such registration statement;

(ix)
enter into such customary agreements (including an underwriting agreement in customary form), which may include indemnification provisions in favor of underwriters and other Persons in addition to, or in substitution for the provisions of paragraph
7(e) hereof, and take such other actions as sellers of a majority of shares of such Registrable Securities or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities;

(x) obtain a cold comfort letter or letters from the Companys independent public accounts in customary form and
covering matters of the type customarily covered by cold comfort letters as the seller or sellers of a majority of shares of such Registrable Securities shall reasonably request;

connection with such registration statement;

(xii) notify counsel for the registered holders of Registrable Securities
included in such registration statement and the managing underwriter or agent,



18



---

immediately, and confirm the notice in writing (i) when the registration statement, or any post-effective amendment to the registration statement, shall
have become effective, or any supplement to the prospectus or any amendment to the prospectus shall have been filed, (ii) of the receipt of any comments from the SEC, (iii) of any request of the SEC to amend the registration statement or
amend or supplement the prospectus or for additional information, and (iv) of the issuance by the SEC of any stop order or similar order suspending the effectiveness of the registration statement or of any order preventing or suspending the use
of any preliminary prospectus, or of the suspension of the qualification of the registration statement for offering or sale in any jurisdiction, or of the institution or threatening of any proceedings for any of such purposes;

(xiii) make every reasonable effort to prevent the issuance of any stop order suspending the effectiveness of the registration statement
or of any order preventing or suspending the use of any preliminary prospectus and, if any such order is issued, to obtain the withdrawal of any such order as soon as practicable;

(xiv) if requested by the managing underwriter or agent or any registered holder of Registrable Securities covered by the registration
statement, promptly incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or agent or such registered holder reasonably requests to be included therein, including, with respect to the number

amendment;

(xv) cooperate with the registered holders of Registrable Securities covered by the registration statement and
the managing underwriter or agent, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing securities to be sold under the registration statement, and enable such securities to be

19



---

underwriters in any road shows or other selling efforts that may be reasonably requested by the registered holders of Registerable Securities in
connection with the methods of distribution for the Registrable Securities.

(f) Information Supplied. The Company may require each
seller of Registrable Securities as to which any registration is being effected to furnish the Company with such information regarding such seller and pertinent to the disclosure requirements relating to the registration and the distribution of such
securities as the Company may from time to time reasonably request.

(g) Restrictions on Disposition. Each registered holder of
Registerable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in paragraph 7(e)(vi), such registered holder will forthwith discontinue disposition of Registrable Securities
pursuant to the registration statement covering such Registrable Securities until such registered holders receipt of the copies of the supplemented or amended prospectus contemplated by paragraph 7(e)(vi), and, if so directed by the Company,
such registered holder will use its reasonable best efforts to deliver to the Company (at the Companys expense) all copies, other than permanent file copies then in such registered holders possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice. In the event the Company shall give any such notice, the period mentioned in paragraph 7(e)(ii) shall be extended by the number of days during the period from and including the
date of the giving of such notice pursuant to paragraph 7(e)(vi) and to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus
contemplated by paragraph 7(e)(vi).

(h) Indemnification.

(i) In the event of any registration of any securities of the Company under the Securities Act pursuant to paragraphs 7(b), 7(c) or 7(d),
the Company shall, and it hereby does, indemnify and hold harmless each seller of any Registrable Securities covered by such registration statement, each Affiliate of such seller and their respective directors, officers, members or general and
limited partners (and any director, officer, and controlling Person of any of the foregoing), each Person who participates as an underwriter in the offering or sale of such securities and each other Person, if any, who controls such seller or any
such underwriter within the meaning of the Securities Act (each an Indemnified Party), against any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in
respect thereof (Claims) and expenses (including reasonable attorneys fees and reasonable expenses of investigation) to which such Indemnified Party may become subject under the Securities Act, common law or otherwise,
insofar as such Claims or expenses arise out of, relate to or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the
Securities Act, any free writing, preliminary, final or summary prospectus contained therein or used in connection with the offering, or any amendment or supplement thereto, (ii) any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein (in the case



20



---

of a prospectus, in light of the circumstances under which they were made) not misleading or (iii) any violation or alleged violation by the Company of
any law or regulation applicable to the Company and relating to action or inaction required of the Company with respect to such registration or the offer or sale of Registrable Securities; provided that the Company shall not be liable to any
Indemnified Party in any such case to the extent that any such Claim or expense arises out of, relates to or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement or
amendment or supplement thereto or in any such free writing, preliminary, final or summary prospectus in reliance upon and in conformity with written information furnished to the Company by or behalf of such seller specifically stating that it is
for use in the preparation thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any Indemnified Party and shall survive the transfer of securities by any seller;

(ii) The Company may require, as a condition to including any Registrable Securities in any registration statement filed in accordance
with paragraphs 7(b), 7(c) or 7(d) herein, that the Company shall have received an undertaking reasonably satisfactory to it from the prospective seller of such Registrable Securities or any underwriter to indemnify and hold harmless (in the same
manner and to the same extent as set forth in paragraph 7(h)(i)) the Company with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from such registration statement, any preliminary, final or summary
prospectus contained therein, or any amendment or supplement thereto, if such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company
by or on behalf of such seller or underwriter specifically stating that it is for use in the preparation of such registration statement, preliminary, final or summary prospectus or amendment or supplement, or a document incorporated by reference
into any of the foregoing. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any of the prospective sellers, or any of their respective Affiliates, directors, officers or
controlling Persons and shall survive the transfer of securities by any seller. In no event shall the liability of any selling holder of Registrable Securities hereunder be greater in amount than the dollar amount of the net proceeds received by
such holder upon the sale of the Registrable Securities giving rise to such indemnification obligation;

(iii) Promptly
after receipt by an Indemnified Party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this paragraph 7(h), such Indemnified Party will, if a claim
in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action or proceeding; provided that the failure of the Indemnified Party to give notice as provided herein shall not
relieve the indemnifying party of its obligations under paragraph 7(h), except to the extent that the indemnifying party is materially prejudiced by such failure to give notice. In case any such action or proceeding is brought against an Indemnified
Party, unless in such Indemnified Partys reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such action or proceeding (in which case the Indemnified Party shall have the right
to assume or continue its own defense and the



21



---

indemnifying party shall be liable for any reasonable expenses therefor, but in no event will bear the expenses for more than one firm of counsel for all
Indemnified Parties in each jurisdiction who shall be approved by the majority of the participating registered holders of Registerable Securities in the registration in respect of which such indemnification is sought), the indemnifying party will be
entitled to participate in and to assume the defense thereof (at its expense), jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such Indemnified Party, and after
notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the indemnifying party will not be liable to such Indemnified party for any legal or other expenses subsequently incurred by the latter in
connection with the defense thereof other than reasonable costs of investigation and shall have no liability for any settlement made by the Indemnified Party without the consent of the indemnifying party, such consent not to be unreasonably
withheld. No indemnifying party will settle any action or proceeding or consent to the entry of any judgment without the prior written consent of the Indemnified Party, unless such settlement or judgment (i) includes as an unconditional term
thereof the giving by the claimant or plaintiff of a release to such Indemnified Party from all liability in respect of such action or proceeding and (ii) does not involve the imposition of equitable remedies or the imposition of any
obligations on such Indemnified Party and does not otherwise adversely affect such Indemnified Party, other than as a result of the imposition of financial obligations for which such Indemnified Party will be indemnified hereunder.

(iv)

(A)
If the indemnification provided for in this paragraph 7(h) from the indemnifying party is unavailable to an Indemnified Party hereunder in respect of any Claim or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Claim or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and Indemnified Party in
connection with the actions which resulted in such Claim or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or
Indemnified Party, and the parties relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party under this paragraph 7(h)(iv) as a result of the Claim and expenses
referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any action or proceeding.



22



---

(B) The parties hereto agree that it would not be just and equitable if contribution
pursuant to this paragraph 7(h)(iv) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in paragraph 7(h)(iv)(A). 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.

(v) Indemnification similar to that specified in this paragraph 7(h) (with appropriate modifications) shall be given by the Company and
each seller of Registrable Securities with respect to any required registration or other qualification of securities under any law, rule or regulation or with any governmental authority other than as required by the Securities Act.

(vi) The obligations of the parties under this paragraph 7(h) shall be in addition to any liability that any party may otherwise have to
any other party.

(i) Required Reports. The Company covenants that it will file the reports required to be filed by it under the
Securities Act and the Exchange Act (or, if the Company is not required to file such reports, it will, upon the request of any registered holder of Registerable Securities, make publicly available such information), and it will take such further
action as any registered holder of Registerable Securities may reasonably request, all to the extent required from time to time to enable such registered holder to sell Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act, as such rule may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. Upon the request of any registered holder of
Registerable Securities, the Company will deliver to such registered holder a written statement as to whether it has complied with such requirements.

(j) Holdback Agreement. If any registration hereunder shall be in connection with an underwritten public offering, each registered holder of Registerable Securities agrees not to effect any public sale or
distribution, including any sale pursuant to Rule 144 under the Securities Act, of any Common Stock of the Company (in each case, other than as part of such underwritten public offering), within 7 days before, or subject to paragraph 7(c) in the
case of a requested registration that has been postponed pursuant to clause (i) thereof, for 90 days (or such lesser period as the managing underwriters may permit) after, the effective date of such registration (except as part of such
registration), and the Company hereby also agrees to use its reasonable best efforts to have each other holder of any Common Stock of the Company purchased from the Company (at any time other than in a public offering) to so agree.

(k) Most Favored Nation. For so long as an Initial Holder owns any of the Warrants, the Company shall grant the Initial Holder any more favorable
registration rights or more favorable other rights, preferences or privileges (whether contractual or embodied in the terms of any security or otherwise) relating to voting or liquidity (other than with respect to price) hereafter granted to any
investor in the Company automatically and without any action on the part of the Initial Holder. The Company shall execute and deliver reasonably promptly all



23



---

agreements or other documents and take all actions reasonably necessary and promptly to execute to give effect to this Section.

(l) Termination. This paragraph 7 shall terminate in its entirety with respect to each registered holder of Registerable Securities when such
registered holder and its Affiliates collectively hold no Registrable Securities and with respect to the Company when all registered holders of Registerable Securities and their Affiliates collectively hold no Registrable Securities.

8. Exchange and Replacement of Warrant Certificates. Each Warrant Certificate is exchangeable without expense, upon the surrender thereof by the
registered holder thereof at the principal executive office of the Company, for a new Warrant Certificate of like tenor and date representing in the aggregate the right to purchase the same number of Warrant Shares in such denominations as shall be
designated by the registered holder thereof at the time of such surrender. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of any Warrant Certificate, and, in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it, and reimbursement to the Company of all reasonable expenses incidental thereto, and upon surrender and cancellation of such Warrant Certificate, if mutilated, the Company will make
and deliver a new Warrant Certificate of like tenor, in lieu thereof.

(e) Assuming obtaining any necessary approval in clause (d), the execution and delivery of this Agreement and the Warrants and the performance by the
Company of the transactions contemplated hereby and thereby will not (i) conflict with or result in a breach of any provision of the articles of incorporation or by-laws of the Company, (ii) result in a default or breach of, or require any

12. Payment of Taxes. The Company will pay all documentary stamp taxes attributable to the initial issuance of the Warrants and of the Warrant Shares upon the exercise of Warrants; provided, however, that the Company
shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance of any Warrant Certificates or any certificates for Warrant Shares in a name other than that of the registered holder of such
Warrant Certificate, and the Company shall not be required to issue or deliver such Warrant Certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have
established to the reasonable satisfaction of the Company that such tax has been paid.

13. Statement on Warrants. Irrespective of
any adjustment in the number or kind of shares issuable upon the exercise of the Warrants or the Exercise Price, Warrant Certificates theretofore or thereafter issued may continue to express the same number and kind of shares and the same Exercise
Price as are stated in the Warrant Certificates initially issuable pursuant to this Agreement.

14. Notices. All notices, requests,
consents and other communications hereunder shall be in writing and shall be deemed to have been duly made when delivered by hand or sent by facsimile transmission (with receipt confirmed), or, if timely delivered to an air courier guaranteeing

15. Amendment. The Company with the consent of the beneficial owners of Warrant Shares
constituting at least two-thirds of the Warrant Shares beneficially owned by parties to this Agreement other than the Company and its Subsidiaries may amend or supplement this Agreement or waive compliance by the Company in a particular instance

beneficial owner) increase the Exercise Price or decrease the number of Warrant Shares issuable upon exercise of any Warrant. For the avoidance of doubt, all of the Warrant Shares underlying an unexercised Warrant shall be deemed beneficially owned
by the registered holder of such Warrant.

16. Successors and Assigns; Benefits of This Agreement. Except as otherwise provided
herein, all of the provisions of this Agreement by or for the benefit of the Company and the registered holders of the Warrants and beneficial owners of the Warrant Shares shall inure to the benefit of their respective successors and assigns

and the registered holders of the unexercised Warrants and beneficial owners of the Warrant Shares any legal or equitable right, remedy or claim under this Agreement, and this Agreement shall be for the sole and exclusive benefit of the Company and
such registered holders and beneficial owners. Prior to the exercise of the Warrants, no holder of a Warrant Certificate, as such, shall be entitled to any rights of a shareholder of the Company, including, without limitation, the right to receive
dividends or subscription rights, the right to vote, to consent, to exercise any preemptive right, to receive any notice of meetings of shareholders for the election of directors of the Company or any other matter or to receive any notice of any
proceedings of the Company, except as may be specifically provided for herein. The holders of the Warrants are not entitled to share in the assets of the Company in the event of the liquidation, dissolution or winding up of the Companys
affairs.

17. Governing Law. This Agreement and each Warrant Certificate issued hereunder shall be deemed to be a contract made
under the laws of the State of New York and for all purposes shall be construed in accordance with the laws of such State, applicable to contracts made and to be performed therein.

18. Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be deemed to
be an original, and such counterparts shall together constitute one and the same instrument.

19. Headings. The headings in this
Agreement are intended solely for convenience of reference and shall be given no effect in the construction or interpretation of this Agreement.

20. Remedies. The Company and the holder hereof each stipulates that the remedies at law of each party hereto in the event of any default or threatened default by the other



28



---

party in the performance or compliance with any of the terms of this Warrant are not and will not be adequate and that, to the fullest extent permitted by
law, such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

21. Severability. The provisions of this Agreement are severable, and if any clause or provision shall be held invalid, illegal or unenforceable
in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect in that jurisdiction only such clause or provision, or part thereof, and shall not in any manner affect such clause or provision in any other jurisdiction
or any other clause or provision of this Agreement in any jurisdiction.

[Seller]

Ladies and Gentlemen:

In connection with the undersigneds (the Investor) proposed purchase of warrants (the
Warrants,) that may be issued by the Company for the purchase of shares of common stock par value $0.01 per share (the Common Stock) of Thornburg Mortgage, Inc., a Maryland corporation (the
Company), from  (Seller), the undersigned confirms and agrees that:



|1. | The undersigned understands and agrees that the Warrants have been offered in a transaction not involving any public offering within the United States within the
meaning of the Securities Act of 1933, as amended (the Securities Act) and that the Warrants have not been registered under the Securities Act and, unless so registered, may not be resold except as permitted in the
following sentence. The undersigned agrees, on its own behalf and on behalf of each account for which it acquires any Warrants that, if in the future it decides to offer, resell, pledge or otherwise transfer such Warrants, such Warrants may be
offered, resold, pledged or otherwise transferred only (a) to the Company or a subsidiary thereof, (b) pursuant to a registration statement that has been declared and is effective under the Securities Act or (c) pursuant to any other
available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of the undersigneds property or the property of such investor account or
accounts be at all times within the undersigneds or their control and subject to compliance with any applicable state securities laws. The undersigned understands that the registrar and transfer agent for the Warrants will not be required to
accept for registration of transfer any Warrants except upon presentation of evidence satisfactory to the Company and the transfer agent that, unless such Warrants are already registered under the Securities Act, an exemption to the registration
requirement under the Securities Act and the rules and regulations thereunder have been complied with. The undersigned further understands that any certificates representing Warrants acquired by it will bear a legend reflecting the substance of this
paragraph. The undersigned acknowledges, on its own behalf and on behalf of any investor account for which it is purchasing the Warrants, that the Company reserves the right to restrict any offer, sale or other transfer of the Warrants pursuant to
clause (c) above or to require the completion, execution and delivery of a letter from the transferee substantially in the form hereof and certifications and other information satisfactory to the Company and the registrar and transfer agent and
an opinion of counsel satisfactory to the Company that the proposed transfer does not require registration under the Securities Act. WITHOUT LIMITING THE FOREGOING, UNLESS AND UNTIL THE COMPANY NOTIFIES YOU OTHERWISE IN WRITING, THE
UNDERSIGNED

COMPANY AND (II) AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT THE PROPOSED TRANSFER DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT.
