 (i) that the Exchange Offer is being made pursuant to this Agreement and that all Registrable Securities

 (iii) that any Registrable Security not tendered will remain outstanding and
continue to accrue interest but will not retain any rights under this Agreement, except as otherwise specified herein; 
 (iv) that any Holder electing to have a Registrable Security exchanged pursuant to the Exchange Offer will be required to (A) surrender such Registrable Security, together with the appropriate
letters of transmittal, to the institution and at the address (located in the Borough of Manhattan, The City of New York) and in the manner specified in the notice, or (B) effect such exchange otherwise in compliance with the applicable
procedures of the depositary for such Registrable Security, in each case prior to the close of business on the last Exchange Date; and 
 (v) that any Holder will be entitled to withdraw its election, not later than the close of business on the expiration of the Exchange Offer, by (A) sending to the institution and at the address
(located in the Borough of Manhattan, The City of New York) specified in the notice, a telegram, telex, facsimile transmission or letter setting forth the name of such Holder, the principal amount of Registrable Securities delivered for exchange and
a statement that such Holder is withdrawing its election to have such Securities exchanged or (B) effecting such withdrawal in compliance with the applicable procedures of the depositary for the Registrable Securities. 

As a condition to participating in the Exchange Offer, a Holder will be required to represent to the Issuers and the Guarantors that
(i) any Exchange Securities to be received by it will be acquired in the ordinary course of its business, (ii) at the time of the commencement of the Exchange Offer it has no arrangement or understanding with any Person to participate in
the distribution (within the meaning of the Securities Act) of the Exchange Securities in violation of the provisions of the Securities Act, (iii) it is not an “affiliate” (within the meaning of Rule 405 under the Securities Act) of

activities, then such Holder will deliver a Prospectus (or, to the extent permitted by law, make available a Prospectus to purchasers) in connection with any resale of such Exchange Securities. 

As soon as practicable after the last Exchange Date, the Issuers and the Guarantors shall: 

(i) accept for exchange Registrable Securities or portions thereof validly tendered and not properly withdrawn pursuant to
the Exchange Offer; 
 (ii) deliver, or cause to be delivered, to the Trustee for cancellation all Registrable
Securities or portions thereof so accepted for exchange by the Issuers and issue, and cause the Trustee to promptly authenticate; and 
 (iii) deliver to each Holder, Exchange Securities equal in principal amount to the principal amount of the Registrable Securities tendered by such Holder. 

The Issuers and the Guarantors shall use their commercially reasonable efforts to complete the Exchange Offer as provided above and shall
comply with the applicable requirements 

  
 -6-









 
of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer shall not be subject to any conditions, other than that
the Exchange Offer does not violate any applicable law or applicable interpretations of the Staff. 
 (b) In the event that
(i) the Issuers and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) above is not available or may not be completed as soon as practicable after the last Exchange Date because it would violate any
applicable law or applicable interpretations of the Staff, (ii) the Exchange Offer is not for any other reason completed on or before the 120th day after the Exchange Offer Registration Statement Filing Deadline (or if such 120th day is not a
Business Day, then the next succeeding Business Day), (iii) upon receipt of a Holders’ request, with respect to any Holder of Registrable Securities that (A) is prohibited by applicable law or SEC policy from participating in the
Exchange Offer, (B) may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or
available for such resales by such Holder or (C) is a broker-dealer and holds Securities acquired directly from the Issuers or one of their affiliates or (iv) upon receipt of a written request (a “Shelf Request”) from any Initial
Purchaser representing that it holds Registrable Securities that are or were ineligible to be exchanged in the Exchange Offer, the Issuers and the Guarantors shall use their commercially reasonable efforts to cause to be filed as soon as practicable
after such determination, date or Shelf Request, as the case may be, a Shelf Registration Statement providing for the sale of all the Registrable Securities by the Holders thereof and to have such Shelf Registration Statement become effective.

 In the event that the Issuers and the Guarantors are required to file a Shelf Registration Statement pursuant to clause
(iv) of the preceding sentence, the Issuers and the Guarantors shall use their commercially reasonable efforts (1) to file the Shelf Registration Statement by the later of (x) the 30th day (or if such 30th day is not a Business Day,
the next succeeding Business Day) after the Issuers determine that they are not required to file the Exchange Offer Registration Statement and (y) the Exchange Offer Registration Statement Filing Deadline and (2) to cause such Shelf
Registration Statement to become effective under the Securities Act on or before the 120th day after such filing (or if such 120th day is not a Business Day, the next succeeding Business Day) pursuant to Section 2(a) with respect to all
Registrable Securities and a Shelf Registration Statement (which may be a combined Registration Statement with the Exchange Offer Registration Statement) with respect to offers and sales of Registrable Securities held by the Initial Purchasers after
completion of the Exchange Offer. 
 The Issuers and the Guarantors agree to use their commercially reasonable efforts to keep
the Shelf Registration Statement continuously effective until the earlier of (i) one year after the initial effectiveness of the Shelf Registration Statement and (ii) the date when all of the Registrable Securities are registered under
such Shelf Registration State and resold pursuant to it (the “Shelf Effectiveness Period”). The Issuers and the Guarantors further agree to supplement or amend the Shelf Registration Statement, the related Prospectus and any Free Writing
Prospectus if required by the rules, regulations or instructions applicable to the registration form used by the Issuers for such Shelf Registration Statement or by the Securities Act or by any other rules and regulations thereunder or if reasonably
requested by a Holder of Registrable Securities with re-

  
 -7-









 
spect to information relating to such Holder, and to use their commercially reasonable efforts to cause any such amendment to become effective, if required, and such Shelf Registration Statement,
Prospectus or Free Writing Prospectus, as the case may be, to become usable as soon as thereafter practicable. The Issuers and the Guarantors agree to furnish to the Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC. 
 (c) The Issuers and the Guarantors shall pay all Registration Expenses
in connection with any registration pursuant to Section 2(a) or Section 2(b) hereof. Each Holder shall pay all underwriting discounts and commissions, brokerage commissions and transfer taxes, if any, relating to the sale or disposition of
such Holder’s Registrable Securities pursuant to the Shelf Registration Statement. 
 (d) An Exchange Offer Registration
Statement pursuant to Section 2(a) hereof will not be deemed to have become effective unless it has been declared effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC or is automatically effective upon filing with the SEC as provided by Rule 462 under the Securities Act. 
 In the event that either (A) the Exchange Offer is not completed on or prior to the 120th day after the Exchange Offer Registration Statement Filing Deadline (or if such 120th day is not a Business
Day, then the next succeeding Business Day) or (B) the Shelf Registration Statement, if required pursuant to Section 2(b)(i), 2(b)(ii), 2(b)(iii) or 2(b)(iv) hereof, does not become effective on or prior to the 120th day after the date on
which the obligation to file the Shelf Registration Statement arises (or if such 120th day is not a Business Day, then the next succeeding Business Day) (each such date in clauses (A) and (B) a “Target Registration Date”), the
interest rate on the Registrable Securities will be increased by 0.25% per annum for the first 90-day period following the Target Registration Date and by an additional 0.25% per annum with respect to each subsequent 90 day period, up to a
maximum of 1.00% per annum, until the Exchange Offer is completed, the Shelf Registration Statement, if required hereby, is effective or all Securities cease to be Registrable Securities, as applicable. 

If the Shelf Registration Statement, if required hereby, has become effective and thereafter either ceases to be effective or the
Prospectus contained therein ceases to be usable, in each case whether or not permitted by this Agreement, at any time during the Shelf Effectiveness Period, and such failure to remain effective or usable exists for more than 90 days (whether or not
consecutive) in any 12-month period, then the interest rate on the Registrable Securities will be increased by 0.25% per annum commencing on the 91st day in such 12-month period for the first 90 day period following such date and by an
additional 0.25% per annum with respect to each subsequent 90 day period, up to a maximum of 1.00% per annum and ending on such date that the Shelf Registration Statement has again become effective or the Prospectus again becomes usable.

 (e) The Issuers and the Guarantors acknowledge that any failure by the Issuers or the Guarantors to comply with their
obligations under Section 2(a) and Section 2(b) hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for
such injuries pre-

  
 -8-









 
cisely and that, in the event of any such failure, the Inital Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Issuers’ and the Guarantors’
obligations under Section 2(a) and Section 2(b) hereof. Notwithstanding the preceding sentence, the provisions for the payment of additional interest set forth in Section 2(d) shall be the only monetary remedy available to Holders for
the Issuers’ and the Guarantors’ failure to cause the Exchange Offer Registration Statement or the Shelf Registration Statement to become effective, or continue to be effective, as the case may be, in accordance with the provisions of this
Agreement. 
 3. Registration Procedures.

otherwise be required to so qualify, (2) file any general consent to service of process in any such jurisdiction or (3) subject itself to taxation in any such jurisdiction if it is not so subject;

delivered (or, to the extent permitted by law, made available) to purchasers of the Registrable Securities, such Prospectus or Free Writing Prospectus, as the case may be, will not contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Issuers and the Guarantors shall notify the Holders of Registrable Securities to suspend use of the
Prospectus or any Free Writing Prospectus as promptly as practicable after the occurrence of such an event, and such Holders hereby agree to suspend use of the Prospectus or any Free Writing Prospectus, as the case may be, until the Issuers and the

 (xv) if
reasonably requested by any Holder of Registrable Securities covered by a Shelf Registration Statement, promptly include in a Prospectus supplement or post-effective amendment such information with respect to such Holder as required to be included
therein and make all required filings of such Prospectus supplement or such post-effective amendment as soon as practicable after the Issuers have received notification of the matters to be so included in such filing; 

(xvi) in the case of a Shelf Registration, enter into such customary agreements and take all such other actions in
connection therewith (including those reasonably requested by the Holders of a majority in principal amount of the Registrable Securities 

  
 -12-









 
covered by the Shelf Registration Statement) in order to expedite or facilitate the disposition of such Registrable Securities including, but not limited to, an Underwritten Offering and in such
connection, (1) to the extent possible, make such representations and warranties to the Holders and any Underwriters of such Registrable Securities with respect to the business of Trans Union and its subsidiaries and the Registration Statement,
Prospectus, any Free Writing Prospectus and documents incorporated by reference or deemed incorporated by reference, if any, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and
confirm the same if and when requested, (2) obtain customary opinions of counsel to the Issuers and the Guarantors (which counsel and opinions, in form, scope and substance, shall be reasonably satisfactory to the Holders and such Underwriters
and their respective counsel) addressed to each selling Holder and any Underwriter of Registrable Securities, covering the matters customarily covered in opinions requested in underwritten offerings, (3) obtain “comfort” letters from
the independent certified public accountants of the Issuers and the Guarantors (and, if necessary, any other certified public accountant of any subsidiary of an Issuer or any Guarantor, or of any business acquired by the Issuers or any Guarantor for
which financial statements and financial data are or are required to be included in the Registration Statement) addressed to any Underwriter of Registrable Securities, such letters to be in customary form and covering matters of the type customarily
covered in “comfort” letters in connection with underwritten offerings, including but not limited to financial information contained in any preliminary prospectus, Prospectus or Free Writing Prospectus and (4) deliver such documents
and certificates as may be reasonably requested by the Holders of a majority in principal amount of the Registrable Securities being sold or the Underwriters, and which are customarily delivered in underwritten offerings, to evidence the continued
validity of the representations and warranties of the Issuers and the Guarantors made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement; and 

(xvii) so long as any Registrable Securities remain outstanding, cause each Additional Guarantor upon the creation or
acquisition by the Issuers of such Additional Guarantor, to execute a counterpart to this Agreement in the form attached hereto as Annex A and to deliver such counterpart, together with an opinion of counsel as to the enforceability thereof against
such entity, to the Initial Purchasers no later than seven Business Days following the execution thereof. 
 (b) In the case of
a Shelf Registration Statement, the Issuers may require each Holder of Registrable Securities to furnish to the Issuers such information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the Issuers
and the Guarantors may from time to time reasonably request in writing. No Holder shall be entitled to be named as a selling security holder in the Shelf Registration Statement or to use the Prospectus forming a part thereof for resales of the
Registrable Securities unless such Holder provides the information reasonably requested by the Issuers within a reasonable time (not to exceed 15 Business Days). 
 (c) In the case of a Shelf Registration Statement, each Holder of Registrable Securities covered in such Shelf Registration Statement agrees that, upon receipt of any notice


  
 -13-









 
from the Issuers and the Guarantors (which shall include receipt of such notice by counsel to such Holder) of the happening of any event of the kind described in Section 3(a)(vi)(3) or
3(a)(vi)(5) hereof, such Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Shelf Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus and any Free
Writing Prospectus contemplated by Section 3(a)(x) hereof and, if so directed by the Issuers and the Guarantors, such Holder will deliver to the Issuers and the Guarantors all copies in its possession, other than permanent file copies then in
such Holder’s possession, of the Prospectus and any Free Writing Prospectus covering such Registrable Securities that is current at the time of receipt of such notice. 
 (d) If the Issuers and the Guarantors shall give any notice to suspend the disposition of Registrable Securities pursuant to a Registration Statement, the Issuers and the Guarantors shall extend the
period during which such Registration Statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of such notice to and including the date when the Holders of
such Registrable Securities shall have received copies of the supplemented or amended Prospectus or any Free Writing Prospectus necessary to resume such dispositions. The Issuers and the Guarantors may give any such notice only three times during
any 365-day period and any such suspensions shall not exceed 30 consecutive days or up to 90 days in the aggregate for each suspension and there shall not be more than three suspensions in effect during any 365-day period. 

(e) The Holders of Registrable Securities covered by a Shelf Registration Statement who desire to do so may sell such Registrable
Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bank or investment banks and manager or managers (each an “Underwriter”) that will administer the offering will be selected by the Holders of a
majority in principal amount of the Registrable Securities included in such offering and be reasonably acceptable to the Issuers and the Guarantors. 
 4. Participation of Broker-Dealers in Exchange Offer. 
 (a) The Staff has
taken the position that any broker-dealer that receives Exchange Securities for its own account in the Exchange Offer in exchange for Securities that were acquired by such broker-dealer as a result of market-making or other trading activities (a
“Participating Broker-Dealer”) may be deemed to be an “underwriter” within the meaning of the Securities Act and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such
Exchange Securities. 
 The Issuers and the Guarantors understand that it is the Staff’s position that if the Prospectus
contained in the Exchange Offer Registration Statement includes a plan of distribution containing a statement to the above effect and the means by which Participating Broker-Dealers may resell the Exchange Securities, without naming the
Participating Broker-Dealers or specifying the amount of Exchange Securities owned by them, such Prospectus may be delivered by Participating Broker-Dealers (or, to the extent permitted by law, made available to purchasers) to satisfy their
prospectus delivery obligation under the Securities Act in connection with resales of Exchange Securities for their own accounts, so long as the Prospectus otherwise meets the requirements of the Securities Act. 

  
 -14-









 (b) In light of the above, and notwithstanding the other provisions of this Agreement, the
Issuers and the Guarantors agree to amend or supplement the Prospectus contained in the Exchange Offer Registration Statement for a period of up to 180 days after the last Exchange Date (as such period may be extended pursuant to Section 3(d)
of this Agreement), in order to expedite or facilitate the disposition of any Exchange Securities by Participating Broker-Dealers consistent with the positions of the Staff recited in Section 4(a) above. The Issuers and the Guarantors further
agree that Participating Broker-Dealers shall be authorized to deliver such Prospectus (or, to the extent permitted by law, make available) during such period in connection with the resales contemplated by this Section 4. 

(c) The Initial Purchasers shall have no liability to the Issuers, any Guarantor or any Holder with respect to any request that they may
make pursuant to Section 4(b) above. 
 5. Indemnification and Contribution. 

(a) The Issuers and each Guarantor, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser and each Holder,
their respective affiliates, directors and officers and each Person, if any, who controls any Initial Purchaser or any Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any
and all losses, claims, damages and liabilities (including, without limitation, reasonable and documented legal fees and expenses of one outside counsel plus one local counsel per jurisdiction incurred in connection with any suit, action or
proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (1) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement
or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (2) any untrue statement or alleged untrue statement of a material fact
contained in any Prospectus, any Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to
state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of,
or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to the Initial Purchaser or information relating to any Holder furnished to the Issuers
in writing through the Representatives or any selling Holder, respectively, expressly for use therein. In connection with any Underwritten Offering permitted by Section 3, the Issuers and the Guarantors, jointly and severally, will also
indemnify the Underwriters, if any, their respective affiliates and each Person who controls such Underwriters (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification
of the Holders, if requested in connection with any Registration Statement, any Prospectus, any Free Writing Prospectus or any Issuer Information. 
 (b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Issuers, the Guarantors, the Initial Purchasers and the other selling Holders, the directors of the Issuers and the
Guarantors, each officer of the Issuers and the Guarantors who signed the Registration Statement and each Person, if any, who controls the Issuers, the Guaran-

  
 -15-









 
tors, any Initial Purchaser and any other selling Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set
forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in
conformity with any information relating to such Holder furnished to the Issuers in writing by such Holder expressly for use in any Registration Statement, any Prospectus or any Free Writing Prospectus. 

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or
asserted against any Person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall promptly notify the Person against whom such
indemnification may be sought (the “Indemnifying Person”) in writing; provided, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above
except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from
any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person
thereof, the Indemnifying Person shall retain one outside counsel plus one local counsel per jurisdiction reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to
this Section 5 that the Indemnifying Person may designate in such proceeding and shall pay the reasonable and documented fees and expenses of such proceeding and shall pay the reasonable and documented fees and expenses of one outside counsel
plus one local counsel per jurisdiction related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such
Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the
Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named
parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in
addition to any one local counsel per jurisdiction) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm (x) for any Initial Purchaser, its affiliates, directors and
officers and any control Persons of such Initial Purchaser shall be designated in writing by the Representatives, (y) for any Holder, its directors and officers and any control Persons of such Holder shall be designated in writing by the
Majority Holders and (z) in all other cases shall be designated in writing by the Issuers. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent
or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of 

  
 -16-









 
such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which
any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional release of such Indemnified Person, in form and substance
reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to any admission of fault, culpability or a failure to act by or on behalf
of any Indemnified Person. 
 (d) If the indemnification provided for in paragraphs (a) and (b) above is unavailable
to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute
to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors from the
offering of the Securities and the Exchange Securities, on the one hand, and by the Holders from receiving Securities or Exchange Securities registered under the Securities Act, on the other hand, or (ii) if the allocation provided by clause
(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Issuers and the Guarantors on the one hand and the Holders
on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Issuers and the Guarantors on the one hand
and the Holders on the other 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 Issuers and the Guarantors or by the Holders and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

(e) The Issuers, the Guarantors and the Holders agree that it would not be just and equitable if contribution pursuant to this
Section 5 were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph
(d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal
or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 5, in no event shall a Holder be required to contribute any amount in excess of the amount by
which the total price at which the Securities or Exchange Securities sold by such Holder exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The
Holders’ obligations to contribute pursuant to this Section 5 are several and not joint. 

  
 -17-









 (f) The remedies provided for in this Section 5 are not exclusive and shall not limit
any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity. 
 (g) The indemnity and
contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of the Initial Purchasers or any
Holder or any Person controlling any Initial Purchaser or any Holder, or by or on behalf of the Issuers or the Guarantors or the officers or directors of or any Person controlling the Issuers or the Guarantors, (iii) acceptance of any of the
Exchange Securities and (iv) any sale of Registrable Securities pursuant to a Shelf Registration Statement. 
 6.
General. 
 (a) Inconsistent Agreements. The Issuers and the Guarantors represent, warrant and agree that
(i) 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 any other outstanding securities issued or guaranteed by the Issuers or any Guarantor under any
other agreement and (ii) neither the Issuers nor any Guarantor has entered into, or on or after the date of this Agreement will enter into, any agreement that is inconsistent with the rights granted to the Holders of Registrable Securities in
this Agreement or otherwise conflicts with the provisions hereof. 
 (b) Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Issuers and the Guarantors have obtained the written
consent of Holders of at least a majority in aggregate principal amount of the outstanding Registrable Securities affected by such amendment, modification, supplement, waiver or consent; provided, that no amendment, modification,
supplement, waiver or consent to any departure from the provisions of Section 5 hereof shall be effective as against any Holder of Registrable Securities unless consented to in writing by such Holder. Any amendments, modifications, supplements,
waivers or consents pursuant to this Section 6(b) shall be by a writing executed by each of the parties hereto. 
 (c)
Notices. All notices and other communications provided for or permitted hereunder shall be made in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication
(i) if to a Holder, at the most current address given by such Holder to the Issuers by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to the Initial Purchasers, the
address set forth in the Purchase Agreement; (ii) if to the Issuers and the Guarantors, initially at the Issuers’ address set forth in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 6(c); and (iii) to such other persons at their respective addresses as provided in the Purchase Agreement and thereafter at such other address, notice of which is given in accordance with the provisions of
this Section 6(c). All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; fifteen Business Days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied or sent by electronic mail; and on the next Business 

  
 -18-









 
Day if timely delivered to an air courier guaranteeing overnight delivery. Copies of all such notices, demands or other communications shall be concurrently delivered by the Person giving the
same to the Trustee, at the address specified in the Indenture. 
 (d) Successors and Assigns. This Agreement shall inure
to the benefit of and be binding upon the successors, assigns and transferees of each of the parties, including, without limitation and without the need for an express assignment, subsequent Holders; provided, that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable Securities in violation of the terms of the Purchase Agreement or the Indenture. If any transferee of any Holder shall acquire Registrable Securities in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be held subject to all the terms of this Agreement, and by taking and holding such Registrable Securities such Person shall be conclusively deemed to have agreed to be bound
by and to perform all of the terms and provisions of this Agreement and such Person shall be entitled to receive the benefits hereof. The Initial Purchasers (in their capacity as Initial Purchasers) shall have no liability or obligation to the
Issuers or the Guarantors with respect to any failure by a Holder to comply with, or any breach by any Holder of, any of the obligations of such Holder under this Agreement. 
 (e) Third Party Beneficiaries. Each Holder shall be a third party beneficiary to the agreements made hereunder between the Issuers and the Guarantors, on the one hand, and the Initial Purchasers,
on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights or the rights of other Holders hereunder. 

(f) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile,
electronic mail or other electronic transmission (i.e., “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart of this Agreement. 

(g) Headings. The headings in this Agreement are for convenience of reference only, are not a part of this Agreement and shall not
limit or otherwise affect the meaning hereof. 
 (h) Governing Law. This Agreement, and any claims, controversy or
dispute arising under or related to this Agreement, shall be governed by and construed in accordance with the laws of the State of New York without regard to conflict of law principles that would result in the application of any laws other than the
laws of the State of New York. 
 (i) Entire Agreement; Severability. This Agreement contains the entire agreement
between the parties relating to the subject matter hereof and supersedes all oral statements and prior writings with respect thereto. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable or against public policy, the remainder of the terms, provisions, covenants and restrictions contained herein shall remain in full force and effect and shall in no way be affected, impaired or
invalidated. The Issuers, the Guarantors and the Initial Purchasers shall endeavor in 

  
 -19-









 
good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which becomes as close as possible to that of the invalid, void or
unenforceable provisions.
