 REGISTRATION RIGHTS AGREEMENT 
  
 December 2, 2003 
  
 Credit Suisse First
Boston LLC 
 Eleven Madison Avenue 
 New York, New York 10010-3629 
  
 Dear Sirs: 
  
 Thornburg Mortgage, Inc., a Maryland corporation (the “Company”), proposes to issue and sell to Credit Suisse First Boston Corporation (the
“Initial Purchaser”), upon the terms set forth in a purchase agreement dated November 17, 2003 (the “Purchase Agreement”), $55 million aggregate principal amount of its 8.00% Senior Notes due 2013 (the “Initial
Securities”). The Initial Securities will be issued pursuant to an Indenture, dated as of May 15, 2003 (the “Indenture”), between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”). As an
inducement to the Initial Purchaser to enter into the Purchase Agreement, the Company agrees with the Initial Purchaser, for the benefit of the Initial Purchaser and the holders of the Securities (as defined below) (collectively, the
“Holders”), as follows: 
  
 1. Registered Exchange
Offer. Unless not permitted by applicable law (after the Company has complied with the ultimate paragraph of this Section 1), the Company shall prepare and, not later than 45 days (such 45th day being a “Filing Deadline”) after the
date on which the Initial Purchaser purchases the Initial Securities pursuant to the Purchase Agreement (the “Closing Date”), file with the Securities and Exchange Commission (the “Commission”) a registration statement (the
“Exchange Offer Registration Statement”) on an appropriate form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer (the “Registered Exchange Offer”) to the Holders of
Transfer Restricted Securities (as defined in Section 6 hereof), who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial
Securities, a like aggregate principal amount of debt securities of the Company issued under the Indenture, identical in all material respects to the Initial Securities and registered under the Securities Act (the “Exchange Securities”).
The Company shall use its best efforts to (i) cause such Exchange Offer Registration Statement to become effective under the Securities Act within 140 days after the Closing Date (such 140th day being an “Effectiveness Deadline”) and (ii)
keep the Exchange Offer Registration Statement effective for not less than 30 days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such period being called the
“Exchange Offer Registration Period”). 
  

 If the Company commences the Registered Exchange Offer, the Company (i) will be entitled to consummate
the Registered Exchange Offer 30 days after such commencement (provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer) and (ii) will be required to
consummate the Registered Exchange Offer no later than 40 days after the date on which the Exchange Offer Registration Statement is declared effective (such 40th day being the “Consummation Deadline”). 
  
 Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities electing to exchange the Initial Securities
for Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business and has no arrangements with any
person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and after their receipt
without any limitations or restrictions under the Securities Act and without material restrictions under the securities laws of the several states of the United States. 
  
 The Company acknowledges that, pursuant to current interpretations by the Commission’s staff of Section 5 of the
Securities Act, in the absence of an applicable exemption therefrom, (i) each Holder which is a broker-dealer electing to exchange Initial Securities, acquired for its own account as a result of market making activities or other trading activities,
for Exchange Securities (an “Exchanging Dealer”), is required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange Offer Procedures”
section and the “Purpose of the Exchange Offer” section, and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities received by such Exchanging
Dealer pursuant to the Registered Exchange Offer and (ii) the Initial Purchaser, if it so elects to sell Exchange Securities acquired in exchange for Initial Securities constituting any portion of an unsold allotment, is required to deliver a
prospectus containing the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale. 
  
 The Company shall use its best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained
therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order to resell
the Exchange Securities; provided, however, that (i) in the case where such prospectus and any amendment or supplement thereto must be delivered by an Exchanging Dealer or the Initial Purchaser, such period shall be the lesser of 180
days and the date on which all Exchanging Dealers and the Initial Purchaser have sold all Exchange Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any
amendment or supplement thereto available to any broker-dealer for use in connection with any resale of any Exchange Securities for a period of not less than 180 days after the consummation of the Registered Exchange Offer. 
  
 If, upon consummation of the Registered Exchange Offer, the Initial Purchaser
holds Initial Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to the Initial Purchaser upon
the written request of the Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held by the Initial Purchaser, a like principal amount of debt securities of the Company issued under the Indenture and identical
in all material respects to the Initial Securities (the “Private Exchange Securities”). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the “Securities.”

  

 2 

 In connection with the Registered Exchange Offer, the Company shall: 
  
 (a) mail to each Holder a copy of the prospectus forming
part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; 
  
 (b) keep the Registered Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice
thereof is mailed to the Holders; 
  
 (c) utilize
the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee; 
  
 (d) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York
time, on the last business day on which the Registered Exchange Offer shall remain open; and 
  
 (e) otherwise comply with all applicable laws. 
  
 As soon as practicable after the close of the Registered Exchange Offer or the Private Exchange, as the case may be, the Company shall: 
  
 (x) accept for exchange all the Initial Securities validly
tendered and not withdrawn pursuant to the Registered Exchange Offer and the Private Exchange; 
  
 (y) deliver to the Trustee for cancellation all the Initial Securities so accepted for exchange; and 
  
 (z) cause the Trustee to authenticate and deliver promptly
to each Holder of the Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for exchange. 
  
 The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one
another on any matter. 
  
 Interest on each Exchange Security and
Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor or, if no
interest has been paid on the Initial Securities, from the date of original issue of the Initial Securities. 
  
 Each Holder participating in the Registered Exchange Offer shall be required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business, (ii) such Holder will have no arrangements or understanding with any person to participate in the distribution of the
Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an “affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will comply with
the registration and prospectus delivery requirements of the Securities Act to the extent applicable, (iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange
Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a 

  

 3 

 
result of market-making activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities. 
  
 Notwithstanding
any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement and any amendment thereto and any prospectus forming part thereof and any supplement thereto complies in all material respects with the
Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and any amendment thereto does not, when it becomes effective, contain 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 and (iii) any prospectus forming part of any Exchange Offer Registration Statement, and any supplement to such prospectus, does not include an untrue statement
of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
  
 If following the date hereof there has been announced a change in Commission
policy with respect to exchange offers that in the reasonable opinion of counsel to the Company raises a substantial question as to whether the Registered Exchange Offer is permitted by applicable federal law, the Company will seek a no-action
letter or other favorable decision from the Commission allowing the Company to consummate the Registered Exchange Offer. The Company will pursue the issuance of such a decision to the Commission staff level. In connection with the foregoing, the
Company will take all such other actions as may be requested by the Commission or otherwise required in connection with the issuance of such decision, including without limitation (i) participating in telephonic conferences with the Commission, (ii)
delivering to the Commission staff an analysis prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that the Registered Exchange Offer should be permitted and (iii) diligently pursuing a
resolution (which need not be favorable) by the Commission staff. 
  
 2. Shelf Registration. If, (i) because of any change in law or in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1
hereof, (ii) the Registered Exchange Offer is not consummated by the 180th day after the Closing Date, (iii) the Initial Purchaser so requests in writing to the Company with respect to the Initial Securities (or the Private Exchange Securities) not
eligible to be exchanged for Exchange Securities in the Registered Exchange Offer and held by it following consummation of the Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer) is not eligible to participate in the
Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable Exchange Securities on the date of the exchange and any such
Holder so requests in writing to the Company, the Company shall take the following actions (the date on which any of the conditions described in the foregoing clauses (i) through (iv) occur, including in the case of clauses (iii) or (iv) the receipt
by the Company of the required notice, being a “Trigger Date”): 
  
 (a) The Company shall promptly (but in no event more than 45 days after the Trigger Date (such 45th day being a “Filing Deadline”)) file with the Commission and thereafter use its best efforts to cause to be
declared effective no later than 140 days after the Trigger Date (such 140th day being an “Effectiveness Deadline”) a registration statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration
Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities by the Holders thereof from time to time in accordance with the methods of
distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf Registration”); provided, however, that no Holder (other than the Initial Purchaser) shall be entitled
to have the Securities held by it covered by such Shelf 

  

 4 

 
Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder. 
  
 (b) The Company shall use its best efforts to keep the Shelf
Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section
3(j) below) from the date of its effectiveness or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted securities (as defined
in Rule 144 under the Securities Act or any successor rule thereof). The Company shall be deemed not to have used its best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that
would result in Holders of the Securities covered thereby not being able to offer and sell such Securities during that period, unless such action is required by applicable law. 
  
 (c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the
Shelf Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable
requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made, not misleading. 
  
 3. Registration Procedures. In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the
following provisions shall apply: 
  
 (a) The
Company shall (i) furnish to the Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event
that the Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its best efforts to reflect in
each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose; (ii) include the information set forth in Annex A hereto on the cover, in Annex B hereto in the “Exchange Offer
Procedures” section and the “Purpose of the Exchange Offer” section and in Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of the Exchange Offer Registration Statement and include
the information set forth in Annex D hereto in the Letter of Transmittal delivered pursuant to the Registered Exchange Offer; (iii) if requested by the Initial Purchaser, include the information required by Items 507 or 508 of Regulation S-K
under the Securities Act, as applicable, in the prospectus forming a part of the Exchange Offer Registration Statement; and (iv) in the case of a Shelf Registration Statement, include the names of the Holders who propose to sell Securities pursuant
to the Shelf Registration Statement as selling securityholders. 
  
 (b) The Company shall give written notice to the Initial Purchaser, the Holders of the Securities and any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934,
as amended (the “Exchange Act”)) of Exchange Securities received by such broker-dealer in the Registered Exchange Offer (a “Participating Broker-Dealer”) from whom the Company has received prior written notice that it will be a
Participating Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii) through (v) 

  

 5 

 
hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made): 
  
 (i) when the Registration Statement or any post-effective
amendment thereto has become effective; 
  
 (ii)
of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information; 
  

(iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation
of any proceedings for that purpose; 
  
 (iv) of
the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

  
 (v) of the happening of any event that
requires the Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the prospectus do not contain an untrue statement of a material fact nor omit to state a material fact required to be
stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading. 
  
 (c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time,
of any order suspending the effectiveness of the Registration Statement. 
  
 (d) The Company shall furnish to each Holder of Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment
thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference). 
  
 (e) The Company shall deliver to each Exchanging Dealer and the Initial Purchaser, and to any other Holder
who so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Initial Purchaser or any such Holder requests, all
exhibits thereto (including those incorporated by reference). 
  
 (f) The Company shall, during the period in which the Company is required to keep a Shelf Registration Statement effective pursuant to Section 2 hereof, deliver to each Holder of Securities included within the
coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request.
The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders of the Securities in connection with the offering and sale of the Securities
covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement.

supplement thereto as such persons may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by the Initial Purchaser, if necessary, any
Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange Offer in connection with the offering and sale of the Exchange Securities covered by the prospectus, or any amendment or supplement
thereto, included in such Exchange Offer Registration Statement. 
  
 (h) Prior to any public offering of the Securities pursuant to any Registration Statement the Company shall register or qualify or cooperate with the Holders of the Securities included therein and their respective
counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing
and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to
(i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 

 
 (i) The Company shall cooperate with the Holders of the
Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such names as the
Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement. 
  
 (j) Upon the occurrence of any event contemplated by paragraphs (ii) through (v) of Section 3(b) above during the period for which the
Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the related prospectus and any other required document so
that, as thereafter delivered to Holders of the Securities or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchaser, the Holders of the Securities and any known Participating Broker-Dealer in accordance with paragraphs (ii)
through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchaser, the Holders of the Securities and any such Participating Broker-Dealers shall suspend
use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the number of days
from and including the date of the giving of such notice to and including the date when the Initial Purchaser, the Holders of the Securities and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus
pursuant to this Section 3(j). 
  
 (k) Not later
than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable trustee
with printed certificates for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company. 
  

 7 

 (l) The Company will comply with all rules and regulations of the Commission to the
extent and so long as they are applicable to the Registered Exchange Offer or the Shelf Registration and will make generally available to its securityholders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings
statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal
quarter commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period. 
  
 (m) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and
containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to
the applicable provisions of the Indenture. 
  
 (n) The Company may require each Holder of Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the Securities as the Company may from
time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after
receiving such request. 
  
 (o) The Company shall
enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as any Holder of the Securities shall reasonably request in order to facilitate the disposition of
the Securities pursuant to any Shelf Registration. 
  
 (p) In the case of any Shelf Registration, the Company shall (i) make reasonably available for inspection by the Holders of the Securities, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and
any attorney, accountant or other agent retained by the Holders of the Securities or any such underwriter all relevant financial and other records, pertinent corporate documents and properties of the Company and (ii) cause the Company’s
officers, directors, employees, attorneys, accountants and auditors to supply all relevant information reasonably requested by the Holders of the Securities or any such underwriter, attorney, accountant or agent in connection with the Shelf
Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that the foregoing
inspection and information gathering shall be coordinated on behalf of the Initial Purchaser by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described in Section 4 hereof. 
  
 (q) In the case of any Shelf Registration, the Company, if
requested by any Holder of Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any, thereof and
dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the

Shelf Registration Statement, the offering and sale of the applicable Securities, or any agreement of the type referred to in Section 3(o) hereof; the compliance as to form of such Shelf Registration Statement and any documents incorporated by
reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; the organization and operation of the Company in conformity with the requirements for qualification and taxation as a real
estate investment trust under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended; the availability of an applicable exemption from the Investment Company Act of 1940, as amended, for the Company and its subsidiaries; and, as
of the date of the opinion and as of the effective date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence from such Shelf Registration Statement and the prospectus included therein,
as then amended or supplemented, and from any documents incorporated by reference therein of an untrue statement of a material fact or the omission to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were filed with the Commission under the Exchange Act); (ii) its officers to execute and deliver all customary
documents and certificates and updates thereof requested by any underwriters of the applicable Securities and (iii) its independent public accountants to provide to the selling Holders of the applicable Securities and any underwriter therefor a

or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the substance thereof as set forth in Section 6(a) of the Purchase Agreement, with appropriate date changes.

to be consummated, upon delivery of the Initial Securities by Holders to the Company (or to such other Person as directed by the Company) in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company
shall mark, or caused to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for the Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial
Securities be marked as paid or otherwise satisfied. 
  
 (t) The Company will use its best efforts to (a) if the Initial Securities have been rated prior to the initial sale of such Initial Securities, confirm such ratings will apply to the Securities covered by a Registration Statement, or (b)
if the Initial Securities were not previously rated, cause the Securities covered by a Registration Statement to be rated with the appropriate rating agencies, if so requested by Holders of a majority in aggregate principal amount of Securities
covered by such Registration Statement, or by the managing underwriters, if any. 
  
 (u) In the event that any broker-dealer registered under the Exchange Act shall underwrite any Securities or participate as a member of an

controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses,
claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages,
liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus
relating to a Shelf Registration, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as
incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that
(i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration
Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by
or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the
indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to
the extent that a prospectus relating to such Securities was required to be delivered by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such
Holder or Participating Broker-Dealer results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final prospectus if the Company had
previously furnished copies thereof to such Holder or Participating Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such
Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with
respect to the indemnification of the Holders of the Securities if requested by such Holders. 
  
 (b) Each Holder of the Securities, severally and not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act
from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any
preliminary prospectus relating to a Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent
that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for
inclusion therein; and, subject to 

  

 11 

 
the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by
the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise
have to the Company or any of its controlling persons. 
  
 (c)
Promptly after receipt by an indemnified party under this Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against
the indemnifying party under this Section 5, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not, in any event, relieve the indemnifying party from any obligations to any
indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified
party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying 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 under this Section 5 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No
indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and does not include a statement as to or an
admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
  
 (d) If the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the
amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing clause
(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the
indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of
the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the
one hand or such Holder or such other indemnified party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by
an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), the Holders of the Securities shall not be required to contribute any amount in
excess of the amount by which the net proceeds received by such Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent 

  

 12 

 
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. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified
party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company. 
  
 (e) The agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration Statement
and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party. 
  
 6. Additional Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”)
with respect to the Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a “Registration Default”): 
  

	 	(i)	any Registration Statement required by this Agreement is not filed with the Commission on or prior to the applicable Filing Deadline; 

  

	 	(ii)	any Registration Statement required by this Agreement is not declared effective by the Commission on or prior to the applicable Effectiveness Deadline; 

  

	 	(iii)	the Registered Exchange Offer has not been consummated on or prior to the Consummation Deadline; or 

  

	 	(iv)	any Registration Statement required by this Agreement has been declared effective by the Commission but (A) such Registration Statement thereafter ceases to be effective during the
period in which such Registration Statement is obligated to be effective or (B) such Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Securities during the periods specified
herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the
statements therein in the light of the circumstances under which they were made not misleading, or (2) it shall be necessary to amend such Registration Statement or supplement to the related prospectus, to comply with the Securities Act or the
Exchange Act or the respective rules thereunder. 

  
 Each of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any
action or inaction by the Commission. 
  
 Additional Interest
shall accrue on the Securities over and above the interest set forth in the title of the Securities from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have
been cured, at a rate of 0.50% per annum (the “Additional Interest Rate”) for the first 90-day period immediately following the occurrence of such Registration Default. The Additional Interest Rate shall increase by an additional 0.50% per
annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum Additional Interest Rate of 2.0% per annum, provided, however, that the Additional Interest Rate on the Securities may not accrue
under more than one of the foregoing clauses (i) through (iv) of this Section 6(a) at any one time. 
  

 13 

 (b) A Registration Default referred to in Section 6(a)(iv) hereof shall be deemed not to have occurred
and be continuing in relation to a Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to
incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events,
with respect to the Company that would need to be described in such Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf
Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured. 
  
 (c) Any amounts of Additional Interest due pursuant to Section 6(a) will be payable in cash on the regular interest payment dates with respect to the
Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest Rate by the principal amount of the Securities and further multiplied by a fraction, the numerator of which is the number of days such
Additional Interest Rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. 
  
 (d) “Transfer Restricted Securities” means each Security until (i) the date on which such Security has been
exchanged by a person other than a broker-dealer for a freely transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an Initial Security for an Exchange
Note, the date on which such Exchange Note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement, (iii) the date on which such
Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (iv) the date on which such Security is distributed to the public pursuant to Rule 144 under the Securities Act
or is saleable pursuant to Rule 144(k) under the Securities Act. 
  
 7. Rules 144 and 144A. The Company shall use its best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file
such reports, it will, upon the request of any Holder of Securities, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such
further action as any Holder of Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Securities without registration under the Securities Act within the limitation of the exemptions provided
by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Initial Securities identified to the Company by the Initial Purchaser upon request. Upon the
request of any Holder of Initial Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to require the
Company to register any of its securities pursuant to the Exchange Act. 
  
 8. Underwritten Registrations. If any of the Transfer Restricted Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering. 
  
 No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such
person’s Transfer Restricted Securities on the basis reasonably provided in any 

  

 14 

 underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 
  
 9. Miscellaneous. 
  
 (a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 1 and 2 hereof may
result in material irreparable injury to the Initial Purchaser or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the
Initial Purchaser or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Sections 1 and 2 hereof. The Company further agrees to waive the defense in any action for specific performance
that a remedy at law would be adequate. 
  
 (b) No Inconsistent
Agreements. The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s securities under any agreement in effect on the date hereof.

  
 (c) Amendments and Waivers. The provisions of this
Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the
Securities affected by such amendment, modification, supplement, waiver or consents. 
  
 (d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees

affiliates (other than subsequent Holders of Securities if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such Securities) shall not be counted in determining whether such consent or approval was given by
the Holders of such required percentage. 
  

 16

Agreement, the Company submits to the nonexclusive jurisdiction of any such court in any such suit or proceeding. To the extent that the Company may acquire any immunity from jurisdiction of any court or from any legal process (whether through

by law.

 ANNEX A 
  
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning
of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial
Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the consummation of the Registered Exchange Offer (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

 ANNEX B 
  
 Each broker-dealer that receives Exchange Securities for its own account in exchange for Initial Securities, where such Initial Securities were acquired
by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.”

 ANNEX C 
  
 PLAN OF DISTRIBUTION 
  
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial
Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the consummation of the Registered Exchange Offer, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until May 15, 2013, all dealers effecting transactions in the Exchange Securities may be required to deliver a
prospectus. 
  
 The Company will not receive any proceeds from any
sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such Exchange Securities. Any
broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Securities may be deemed to be an
“underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

  
 For a period of 180 days after the Expiration Date the Company
will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to the
Exchange Offer (including the expenses of one counsel for the Holders of the Securities) other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Securities (including any broker-dealers) against certain
liabilities, including liabilities under the Securities Act.

 [Back of Note] 
 8.00% Senior Notes due 2013 
  
 Capitalized terms used herein shall have the meanings assigned to them in the First Supplemental Indenture referred to below unless otherwise indicated. 
  
 1. INTEREST. Thornburg Mortgage, Inc., a Maryland corporation (the
“Company”), promises to pay interest on the principal amount of this Note at 8.00% per annum from November 15, 2003 until maturity. The Company will pay interest semi-annually in arrears on May 15 and November 15 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on this Note will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from
November 15, 2003; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue
from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be May 15, 2004. The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at the rate then in effect; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
  
 2. METHOD OF PAYMENT. The Company will pay interest on
the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 1 or November 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.14 of the First Supplemental Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the
Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and
provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest, and premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer
instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. The Company reserves the right to pay
interest to Holders of Notes by check mailed to such Holders at their registered addresses or by wire transfer to Holders of at least $5 million aggregate principal amount of Notes. 
  
 3. PAYING AGENT AND REGISTRAR. Initially,
Deutsche Bank Trust Company Americas, the Trustee under the First Supplemental Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its
Subsidiaries may act in any such capacity. 
  

 4. INDENTURE. The Company issued the Notes under an Indenture dated
as of May 15, 2003 as supplemented by a First Supplemental Indenture dated as of May 15, 2003 (collectively, the “Indenture”) between the Company and the Trustee. The terms of the Notes include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company. The Company is issuing $55.0 million
in aggregate principal amount on the date of this Note and may issue Additional Notes in accordance with the terms of the Indenture. 
  
 5. OPTIONAL REDEMPTION. 
  
 Optional Redemption. At any time on or after May 15, 2008, the Notes may be redeemed or purchased in whole or in part
at the Company’s option at a price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued but unpaid interest, if any, to, the date of redemption or purchase (the “Redemption Date”) (subject to
the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). Such redemption or purchase may be made upon notice mailed by first-class mail to each Holder’s registered address, not
less than 30 nor more than 60 days prior to the Redemption Date. 
  
 “Applicable Premium” means, with respect to a Note at any Redemption Date: (1) 104% of the principal amount of such Note if the Redemption Date is on or after May 15, 2008 and before May 15, 2009; (2) 102.667% of the
principal amount of such Note if the Redemption Date is on or after May 15, 2009 and before May 15, 2010; (3) 101.333% of the principal amount of such Note if the Redemption Date is on or after May 15, 2010 and before May 15, 2011; and (4) 0% of the
principal amount of such Note if the Redemption Date is on or after May 15, 2011. Calculation of the Applicable Premium will be made by the Company or on behalf of the Company by such Person as the Company shall designate; provided, however,
that such calculation shall not be a duty or obligation of the Trustee. 
  
 “Treasury Rate” means, with respect to a Redemption Date, the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in
the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two Business Days prior to such Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of
similar market data)) most nearly equal to the period from such Redemption Date to May 15, 2013; provided, however, that if the period from such Redemption Date to May 15, 2013 is not equal to the constant maturity of the United States
Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which
such yields are given, except that if the period from such Redemption Date to May 15, 2013 is 
  

 less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant
maturity of one year shall be used. 
  
 Optional Redemption
Upon Equity Offerings. At any time, or from time to time, on or prior to May 15, 2006, the Company may, at its option, use the net cash proceeds of one or more Equity Offerings to redeem up to 35% of the principal amount of the Notes issued
under the Indenture at a redemption price of 108% of the principal amount thereof plus accrued and unpaid interest thereon, if any, to the date of redemption; provided that: 
  

	 	(1)	at least 65% of the principal amount of Notes issued under the Indenture remains outstanding immediately after any such redemption; and 

  

	 	(2)	the Company makes such redemption not more than 60 days after the consummation of any such Equity Offering. 

  
 6. MANDATORY REDEMPTION.

  
 Except as set forth in paragraph 7 below, the Company shall
not be required to make mandatory redemption payments with respect to the Notes. 
  
 7. REPURCHASE AT OPTION OF HOLDER. 
  
 Upon the occurrence of a Change of Control, the Company will be required to offer to purchase all of the outstanding Notes
at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the date of repurchase. 
  
 8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not
more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes
held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption. 
  
 9. DENOMINATIONS AND TRANSFER. The Notes are in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and the Company and the Trustee may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. 
  
 10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes. 
  

 11. AMENDMENT, SUPPLEMENT AND
WAIVER. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the written consent of the Holders of at least a majority in principal amount of the then outstanding Notes
voting as a single class, and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the written consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a
single class. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for certificated Notes in addition to or in place of uncertificated
Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not
adversely affect in any material respects the rights under the Indenture of any such Holder, to comply with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act or to
evidence and provide for the acceptance of appointment under the Indenture of a successor Trustee. 
  
 12. DEFAULTS AND REMEDIES. Events of Default are set forth in the Indenture. If any
Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in writing in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default
or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then
outstanding by written notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of
interest on, or the principal of, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default. 
  
 13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 
  
 14. NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator or
stockholder, of the Company, as such, shall not have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Note 
  

 waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the
Notes. 
  
 15.
AUTHENTICATION. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 
  
 16. ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

 
 17. CUSIP NUMBERS.
Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience
to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
  
 The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Requests may be made to:
