to such depositary of one or more replacement Notes in global form in an equivalent principal amount thereto for the account of such Holders in accordance with the Indenture shall satisfy such authentication and delivery requirement.

 The Issuer and the Guarantors shall use their commercially reasonable efforts to complete the
Exchange Offer as provided above and shall comply in all material respects with the applicable requirements of the Securities Act, the Exchange Act and other applicable laws and regulations in connection with the Exchange Offer. The Exchange Offer

applicable law or applicable interpretations of the Staff, (ii) any action or proceeding is instituted in or threatened in any court or by or before any governmental agency with respect to the Exchange Offer that, in the reasonable judgment of
the Issuer and the Guarantors, might materially impair the ability of the Issuer and the Guarantors to proceed with the Exchange Offer or (iii) any government or regulatory approval to conduct the Exchange Offer has not been obtained that, in
the reasonable judgment of the Issuer and the Guarantors, is necessary for the consummation of the Exchange Offer. 
 (b) In the event that
(i) the Issuer and the Guarantors determine that the Exchange Offer Registration provided for in Section 2(a) hereof is not available or the Exchange Offer may not be completed as soon as practicable after the last Exchange Date because it
would violate an applicable law or applicable interpretations of the Staff, (ii) the Exchange Offer, for any other reason, is not completed by the Target Registration Date or (iii) upon receipt of a written request (a “Shelf
Request”) within 30 days after the consummation of the Exchange Offer from any Initial Purchaser representing that it holds Registrable Securities that are or were ineligible to be exchanged in the Exchange Offer, or (iv) any Holder is
not eligible to participate in the Exchange Offer pursuant to Section 2(a) or, in the case of a Holder who does participate in the Exchange Offer, does not receive freely tradeable Exchange Securities and so notifies the Issuer within 30 days
after such Holder first becomes aware of such restrictions, the Issuer and the Guarantors shall use their commercially reasonable efforts to file with the SEC as soon as practicable after such determination, notification 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 use their commercially reasonable efforts to have such Shelf Registration Statement become effective; provided
that no Holder will be entitled to have any Registrable Securities included in any Shelf Registration Statement, or entitled to use the prospectus forming a part of such Shelf Registration Statement, until such Holder shall have delivered a
completed and signed Notice and Questionnaire and provided such other information regarding such Holder to the Issuer as is contemplated by Section 3(b) hereof. 

In the event that the Issuer and the Guarantors are required to file a Shelf Registration Statement pursuant to clause (iii) of the
preceding paragraph, the Issuer and the Guarantors shall use their commercially reasonable efforts to file and have become effective both an Exchange Offer Registration Statement pursuant to Section 2(a) hereof 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. 

  
 9 








 The Issuer and the Guarantors agree to use their commercially reasonable efforts to keep the
Shelf Registration Statement continuously effective until the earlier of the (1) one-year anniversary of the effectiveness of the Shelf Registration Statement and (2) date when the Securities cease to be Registrable Securities (the
“Shelf Effectiveness Period”); provided that the Issuer and the Guarantors may, for a period (a “Blackout Period”) of up to 60 days in any three-month period, not to exceed 90 days in any twelve-month period,
suspend the use of the Prospectus contained in the Shelf Registration Statement if the Board of Directors of Holdings reasonably determines that the Shelf Registration Statement is not usable under circumstances relating to corporate developments,
public filings with the SEC and similar events. 
 The Issuer 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 Issuer for such Shelf Registration Statement or by the Securities Act or by any
other rules and regulations thereunder or if reasonably requested by the Holders of a majority in aggregate principal amount of the Registrable Securities with respect to information relating to one or more of such Holders, and to use their
commercially reasonable efforts to cause any such amendment to become effective, if required. The Issuer and the Guarantors agree to furnish to the Participating Holders copies of any such supplement or amendment promptly after its being used or
filed with the SEC. 
 (c) The Issuer 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. 
 The Issuer and the Initial Purchasers agree that the Holders will suffer damages if the
Issuer fails to fulfill its obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Issuer and the Guarantors agree to pay, jointly and
severally, as liquidated damages and the sole remedy for monetary damages in connection with a Registration Default, additional interest on the outstanding Registrable Securities if a Registration Default occurs. The interest rate on the Registrable
Securities will be increased by (i) 0.25% per annum for the first 90-day period beginning on the day immediately following such Registration Default and (ii) an additional 0.25% per annum with respect to the subsequent 90-day
period, in each case to but excluding the date such Registration Default ends. A Registration Default ends when the Securities cease to be Registrable Securities or, if earlier, (1) in the case of a Registration Default under clause (i) of
the definition thereof, when the Exchange Offer is completed, (2) in the case of a Registration Default under clause (ii) or clause (iii) of the definition thereof, when the Shelf Registration Statement becomes effective or
(3) in the case of a Registration Default under clause (iv) of the definition thereof, subject to any Blackout Period, when the Shelf Registration Statement again becomes effective. If at any time more than one Registration Default has
occurred and is continuing, then, until the next date that there is no Registration Default, the increase in interest rate provided for by this paragraph shall apply as if there occurred a single Registration Default that begins on the date that the
earliest such Registration Default occurred and ends on such next date that there is no Registration Default.

Securities or otherwise) are outstanding, (y) the Market Maker proposes to make a market in the Registrable Securities or the Exchange Securities as part of its business in the ordinary course and (z) in the reasonable opinion of Goldman,

whom the Market-Making Conditions apply at the applicable time shall be entitled to the use of the Market-Making Registration Statement and related provisions of this Agreement at any time). The Issuer and the Guarantors shall use their commercially
reasonable efforts to file with the SEC, a Market-Making Registration Statement providing for the registration, and the sale on a continuous or delayed basis in secondary transactions by the Market Maker, of Registrable Securities or Exchange
Securities (such filing, a “Market-Making Registration”. The Issuer and the Guarantors agree to use their commercially reasonable efforts (i) to have such Market-Making Registration Statement become effective on or prior to

has been filed or any amendment or supplement to the Prospectus or any Free Writing Prospectus has been filed, (2) of any comments or request by the SEC or any state securities authority for amendments and supplements to a Registration
Statement, Prospectus or any Free Writing Prospectus or for additional information after the Registration Statement has become effective, (3) of the issuance by the SEC or any state securities authority of any stop order suspending the
effectiveness of a Registration Statement or the initiation of any proceedings for that purpose, including the receipt by the Issuer of any notice of objection of the SEC to the use of a Registration Statement or any post-effective amendment thereto
pursuant to Rule 401(g)(2) under the Securities Act, or the happening of any event that causes the Issuer to become an “ineligible issuer” as defined in Rule 405 under the Securities Act, (4) if, between the applicable effective date
of a Shelf Registration Statement and the closing of any sale of Registrable Securities covered thereby, the representations and warranties of the Issuer or any Guarantor contained in any underwriting agreement, securities sales agreement or other
similar agreement, if any, relating to an offering of such Registrable Securities cease to be true and correct in all material respects, (5) if, between the applicable effective date of a Shelf Registration Statement and the closing of any sale
of Registrable Securities covered thereby or during the effectiveness of a Market-Making Registration Statement pursuant to Section 2(d) hereof, the Issuer or any Guarantor receives any notification with respect to the suspension of the
qualification of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose, (6) of the happening of any event during the period a Registration Statement is effective that makes any statement
made in such Registration Statement or the related Prospectus or any Free Writing Prospectus untrue in any material respect or that requires the making of any changes in such Registration Statement or Prospectus or any Free Writing Prospectus in
order to make the statements therein not misleading and (7) of any determination by the Issuer or any Guarantor that a post-effective amendment to a Registration Statement or any amendment or supplement to the Prospectus or any Free Writing
Prospectus would be appropriate; 

  
 13 








 (vii) use their commercially reasonable efforts to obtain the withdrawal of any order suspending
the effectiveness of a Registration Statement or, in the case of a Shelf Registration or Market-Making Registration, the resolution of any objection of the SEC pursuant to Rule 401(g)(2) under the Securities Act, including by filing an amendment to
such Registration Statement on the proper form, as soon as practicable and provide immediate notice to each Holder, Participating Holder or Market Maker, as the case may be, of the withdrawal of any such order or such resolution; 

(viii) in the case of a Shelf Registration or a Market-Making Registration, to the extent the Registrable Securities or Exchange Securities are
certificated, reasonably cooperate with the Participating Holders or the Market Maker, as the case may be, to facilitate the timely preparation and delivery of certificates representing Registrable Securities or Exchange Securities to be sold and
not bearing any restrictive legends and enable such Registrable Securities or Exchange Securities to be issued in such denominations and registered in such names (consistent with the provisions of the Indenture) as such Participating Holders or the
Market Maker may reasonably request at least one Business Day prior to the closing of any sale of Registrable Securities or Exchange Securities; 

(ix) subject to any Blackout Period, upon the occurrence of any event contemplated by Section 3(a)(vi)(5) hereof, use their commercially
reasonable efforts to prepare and file with the SEC a supplement or post-effective amendment to the applicable Registration Statement or the related Prospectus or any Free Writing Prospectus or any document incorporated therein by reference or file
any other required document so that, as thereafter delivered (or, to the extent permitted by law, made available) to purchasers of the Registrable Securities or Exchange Securities, as the case may be, 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 Issuer shall
notify the Participating Holders (in the case of a Shelf Registration Statement), the Initial Purchasers and any Participating Broker-Dealers known to the Issuer (in the case of an Exchange Offer Registration Statement) and the Market Maker (in the
case of a Market-Making Registration Statement) to suspend use of the Prospectus or any Free Writing Prospectus as promptly as practicable after the occurrence of such an event, and such Participating Holders, such Participating Broker-Dealers, the
Initial Purchasers and the Market Maker, as applicable, hereby agree to suspend use of the Prospectus or any Free Writing Prospectus, as the case may be, until the Issuer and the Guarantors have amended or supplemented the Prospectus or the Free
Writing Prospectus, as the case may be, to correct such misstatement or omission; 
 (x) a reasonable time prior to the filing of any
Registration Statement, any Prospectus, Free Writing Prospectus or amendment of or supplement to a Registration Statement or a Prospectus or Free Writing Prospectus (excluding any document that is to be incorporated by reference into a Registration
Statement, Prospectus or Free Writing Prospectus), provide copies of such document to the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, to the Participating Holders and their counsel) or in the case of a
Market-Making Registration Statement, to the Market Maker and its counsel, and make such of the representatives of the Issuer and Holdings as shall be reasonably requested by the Initial Purchasers or their counsel (and, in the case of a


  
 14 








 
Shelf Registration Statement, the Participating Holders or their counsel) or in the case of a Market-Making Registration Statement, the Market Maker or its counsel, available for discussion of
such document; and the Issuer and the Guarantors shall not, at any time after initial filing of a Registration Statement, use or file any Prospectus, Free Writing Prospectus or amendment of or supplement to a Registration Statement or a Prospectus
or Free Writing Prospectus (excluding any document that is to be incorporated by reference into a Registration Statement, Prospectus or Free Writing Prospectus) of which the Initial Purchasers and their counsel (and, in the case of a Shelf
Registration Statement, the Participating Holders and their counsel) or in the case of a Market-Making Registration Statement, the Market Maker and its counsel, shall not have previously been advised and furnished a copy or to which the Initial
Purchasers or their counsel (and, in the case of a Shelf Registration Statement, the Participating Holders or their counsel) or in the case of a Market-Making Registration Statement, the Market Maker and its counsel, shall reasonably object; 

(xi) use their commercially reasonable efforts to obtain a CUSIP number for all Exchange Securities or Registrable Securities, as the case may
be, not later than the initial effective date of a Registration Statement; 
 (xii) use their commercially reasonable efforts to cause the
Indenture to be qualified under the Trust Indenture Act in connection with the registration of the Exchange Securities or Registrable Securities, as the case may be; reasonably cooperate with the Trustee and the Holders to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance with the terms of the Trust Indenture Act; and execute, and use their commercially reasonable efforts to cause the Trustee to execute, all documents as may be required
to effect such changes and all other forms and documents required to be filed with the SEC to enable the Indenture to be so qualified in a timely manner; 

(xiii) in the event that the filing of a Registration Statement requires the appointment of a new trustee under the Indenture, appoint a new
trustee thereunder pursuant to the applicable provisions of the Indenture; 
 (xiv) in the case of a Shelf Registration or a Market-Making
Registration, make available for inspection by a representative of the Participating Holders (an “Inspector”), any Underwriter participating in any disposition pursuant to such Shelf Registration Statement, the Market Maker (in the
case of a Market-Making Registration), any attorneys and accountants designated by a majority in aggregate principal amount of the Notes held by the Participating Holders, any attorneys and accountants designated by such Underwriter, and any
attorneys and accountants designated by the Market Maker, as the case may be, at reasonable times and in a reasonable manner, all pertinent financial and other records, documents and properties of Holdings and the Guarantors, and cause the
respective officers, directors and employees of Holdings and the Guarantors to supply all information reasonably requested by any such Inspector, Underwriter, Market Maker, attorney or accountant, as the case may be, in connection with such Shelf
Registration Statement or Market-Making Registration Statement; provided that if any such information is identified by Holdings or any Guarantor as being confidential or 

  
 15 








 
proprietary, each Person receiving such information shall take such actions as are reasonably necessary to protect the confidentiality of such information to the extent such action is otherwise
not inconsistent with, an impairment of or in derogation of the rights and interests of any such Inspector, Holder, Underwriter or Market Maker; 

(xv) in the case of a Shelf Registration, use their commercially reasonable efforts to cause all Registrable Securities to be listed on any
securities exchange or any automated quotation system on which similar securities issued or guaranteed by the Issuer or any Guarantor are then listed if requested by the Majority Holders, to the extent such Registrable Securities satisfy applicable
listing requirements; 
 (xvi) if reasonably requested by any Participating Holder or the Market Maker, promptly include in a Prospectus
supplement or post-effective amendment such information with respect to such Participating Holder or Market Maker, as such Participating Holder or Market Maker, as the case may be, reasonably requests to be included therein and make all required
filings of such Prospectus supplement or such post-effective amendment as soon as the Issuer has received notification of the matters to be so included in such filing; 

(xvii) in the case of a Shelf Registration or Market-Making Registration, enter into such customary agreements and take all such other actions
in connection therewith (including those requested by the Holders of a majority in principal amount of the Registrable Securities covered by the Shelf Registration Statement) in order to expedite or facilitate the disposition of such Registrable
Securities or Exchange Securities, as the case may be, including (in the case of a Shelf Registration), but not limited to, an Underwritten Offering and in connection therewith, (1) to the extent possible, agree to customary indemnity and
contribution provisions and make such representations and warranties to the Participating Holders and any Underwriters of such Registrable Securities with respect to the business of the Issuer, Holdings and the Issuer’s subsidiaries and the
Registration Statement, Prospectus, any Free Writing Prospectus and documents incorporated by reference or deemed incorporated by reference therein, 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) solely with respect to an Underwritten Offering, obtain opinions of counsel to the Issuer and the Guarantors (which counsel and opinions, in form, scope and
substance, shall be reasonably satisfactory to the Participating Holders, such Underwriters and their respective counsel) addressed to each Participating Holder and Underwriter of Registrable Securities, covering the matters customarily covered in
opinions requested in underwritten offerings, (3) solely with respect to an Underwritten Offering, obtain “comfort” letters from the independent registered public accountants of Holdings (and, if necessary, any other registered public
accountant of any subsidiary of the Issuer, including Constant Contact, or of any other business acquired by the Issuer for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to
each Participating Holder (to the extent permitted by applicable professional standards) and 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 

  
 16 








 
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
Issuer and the Guarantors made pursuant to clause (1) above and to evidence compliance with any customary conditions contained in an underwriting agreement; 

(xviii) make generally available to each Participating Holder no later than eighteen months after the effective date of a Registration
Statement, an “earning statement” of Holdings complying with Section 11(a) of the Securities Act (including, at the option of the Issuer, Rule 158 thereunder); and 

(xix) so long as any Registrable Securities remain outstanding, cause each Additional Guarantor upon the creation or acquisition by the Issuer
of such Additional Guarantor, to execute a counterpart to this Agreement in the form attached hereto as Annex B 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 five Business Days following the execution thereof. 
 (b) In the case of a Shelf Registration Statement,
the Issuer may require each Holder of Registrable Securities to furnish to the Issuer a Notice and Questionnaire and such other information regarding such Holder and the proposed disposition by such Holder of such Registrable Securities as the
Issuer may from time to time reasonably request in writing. 
 (c) Each Participating Holder and the Market Maker agree that, upon receipt of
any notice from the Issuer of the occurrence of any event of the kind described in Section 3(a)(vi)(3) or Section 3(a)(vi)(5) hereof or of a Blackout Period, such Participating Holder or the Market Maker, as the case may be, will forthwith
discontinue disposition of Registrable Securities or Exchange Securities, as the case may be, pursuant to the applicable Registration Statement until such Participating Holder’s or the Market Maker’s receipt of the copies of the
supplemented or amended Prospectus and any related Free Writing Prospectus or notice that the Blackout Period has terminated and, if so directed by the Issuer, such Participating Holder or Market Maker, as the case may be, will deliver to the Issuer
all copies in its possession, other than permanent file copies then in such Participating Holder’s or the Market Maker’s possession, of the Prospectus and any Free Writing Prospectus covering such Registrable Securities or Exchange
Securities that is current at the time of receipt of such notice. 
 (d) If the Issuer shall give any notice to suspend the disposition of
Registrable Securities pursuant to an Exchange Offer Registration Statement or a Shelf Registration Statement or of any Blackout Period with respect thereto, the Issuer 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 or any other notice necessary to resume such dispositions. 

  
 17 








 (e) The Participating Holders who desire to do so may sell 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. 
 (f) Each Participating Holder and the Market Maker will furnish
to the Issuer and the Guarantors such information regarding such Participating Holder or the Market Maker, as the case may be, and the distribution of such Registrable Securities or Exchange Securities as the Issuer may from time to time reasonably
request in writing. Each Participating Holder and the Market Maker agree to notify the Issuer and the Guarantors as promptly as practicable of any inaccuracy or change in information previously furnished by such Participating Holder or the Market
Maker, as the case may be, to the Issuer and the Guarantors or of the happening of any event, in either case as a result of which any Prospectus relating to such registration contains an untrue statement of a material fact regarding such
Participating Holder or the Market Maker or the distribution of such Registrable Securities or Exchange Securities or omits to state any material fact regarding such Participating Holder or the Market Maker or the distribution of such Registrable
Securities or Exchange Securities required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and to furnish to the Issuer and the Guarantors promptly any
additional information required to correct and update any previously furnished information or required such that such Prospectus shall not contain, with respect to such Participating Holder or the Market Maker or the distribution of such Registrable
Securities or Exchange Securities, 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, in light of the circumstances in which they were made, not
misleading. 
 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 Issuer 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. 

  
 18 








 (b) In light of the above, and notwithstanding the other provisions of this Agreement, the Issuer
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 Exchange Offer Registration Statement becomes effective (as such period may be extended
pursuant to Section 3(c) hereof), 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 Issuer 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 Issuer, any Guarantor or any Holder with respect to any request that they may
make pursuant to Section 4(b) hereof. 
 5. Indemnification and Contribution. (a) Each of the Issuer, the Endurance
Guarantors, and upon execution and delivery of the Registration Rights Agreement Joinder, each of the Constant Contact Guarantors, jointly and severally with the Issuer and each of the Endurance Guarantors, hereby agrees to indemnify and hold
harmless each of the Participating Holders as holders of Registrable Securities included in an Exchange Offer Registration Statement and, each of the Participating Holders as holders of Registrable Securities included in a Shelf Registration
Statement and the Market Maker as a holder of Registrable Securities or Exchange Securities included in a Market-Making Registration Statement from and against any loss, claim, damage or liability, joint or several, to which such Participating
Holder or the Market Maker may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) an untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement under which such Registrable Securities or Exchange Securities were registered under the Securities Act, or any Prospectus or Free Writing Prospectus contained therein or furnished by the Issuer to any
such Participating Holder or the Market Maker, or (ii) the omission or alleged omission to state therein any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading, and shall reimburse each such Participating Holder and the Market Maker promptly upon demand, for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against any
such loss, claim damage, liability or action as such expenses are incurred; provided, however, that the Issuer and the Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises
out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, Prospectus or Free Writing Prospectus, in reliance upon and in conformity with written information
furnished to the Issuer by such person specifically for inclusion therein. The foregoing indemnity agreement is in addition to any liability that the Issuer or the Guarantors may otherwise have to each such Participating Holder and the Market Maker.


  
 19 








 (b) Each Holder, severally and not jointly, hereby agrees to indemnify and hold harmless, the
Issuer, the Initial Purchasers, the Market Maker and the other selling Holders, the Endurance Guarantors, and upon execution and delivery of the Registration Rights Agreement Joinder, each of the Constant Contact Guarantors and their respective
officers, each of their respective directors, each of their respective officers who signed the Registration Statement and each Person, if any, who controls, as of the date hereof, the Issuer and each Guarantor, any Initial Purchaser, the Market
Maker 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 written information concerning such Holder furnished to the
Issuer and the Guarantors by or behalf of that Holder specifically for inclusion in any Registration Statement, any Prospectus and any Free Writing Prospectus. The foregoing indemnity agreement is in addition to any liability that any Holder may
otherwise have to the Issuer, any Guarantor or any such director, officer or controlling person. 
 (c) Promptly after receipt by an
indemnified party under either paragraph (a) or (b) above (such party, an “Indemnified Person”) of notice of claim or commencement of any action, the Indemnified Person shall, if a claim in respect thereof is to be made
against the indemnifying party under either paragraph (a) or (b) above, notify the Person against whom such indemnification may be sought (the “Indemnifying Person”) in writing of the claim or the commencement of that
action; provided, however, that the failure to so 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 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 claim or action shall be brought against an Indemnified Person, and it shall notify the Indemnifying Person thereof, the Indemnifying Person shall be entitled to participate therein and,
to the extent that it wishes, jointly with any other similarly notified Indemnifying Person, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Person. After notice from the Indemnifying Person to the Indemnified
Person of its election to assume the defense of such claim or action, the Indemnifying Person shall not be liable to the Indemnified Person under this Section 5 for any legal or other expenses subsequently incurred by the Indemnified Person in
connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Indemnified Person shall have the right to employ counsel to represent the Indemnified Person and such Indemnified Person’s
respective directors, officers and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Person against the Indemnifying Person under this Section 5, if
(i) the Indemnifying Person and the Indemnified Person shall have so mutually agreed; (ii) the Indemnifying Person fails within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the
Indemnified Person and its respective directors, officers and controlling persons shall have reasonably concluded, based on the 

  
 20 








 
advice of counsel, that there may be legal defenses available to them 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, on the one hand, and the Indemnified Person, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to
actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Indemnifying Person. No Indemnifying Person shall (x) without the prior written consent of the
Indemnified Persons (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not the Indemnified Persons are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each Indemnified Person from all
liability arising out of such claim, action, suit or proceeding 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 Person, or (y) be liable for any settlement of
any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the Indemnifying Person or if there be a final judgment of the plaintiff in any such action, the Indemnifying
Person agrees to indemnify and hold harmless any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. 

(d) If the indemnification provided for in this Section 5 shall for any reason be unavailable to or insufficient to hold harmless an
Indemnified Person under paragraph (a) or (b) above in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein (other than by virtue of the failure of an Indemnified Person to notify the
Indemnifying Person of its right to indemnification pursuant to paragraph (a) or (b) above, where such failure materially prejudices the Indemnifying Person (through the forfeiture of substantive rights or defenses)), then each
Indemnifying Person shall, in lieu of indemnifying such Indemnified Person, contribute to the amount paid or payable by such Indemnified Person as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such
proportion as shall be appropriate to reflect the relative benefits received by the Indemnifying Person, on the one hand, and the Indemnified Person, on the other, from the offering of the Securities or the Exchange Securities, or (ii) if the
allocation provided by clause (i) above 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
Person, on the one hand, and the Indemnified Person, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable
considerations. The relative benefits received by the Issuer and the Guarantors, on the one hand, and the Holders on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of
the Securities (before deducting expenses) received by the Issuer and the Guarantors, on the one hand, and the total discounts and commissions received by the Holders with respect to the Securities, on the other hand, bear to the total gross
proceeds from the offering of the Securities. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission 


  
 21 








 
to state a material fact relates to information supplied by the Issuer and the Guarantors, on the one hand, or the Holders on the other hand, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such statement or omission and any other equitable considerations appropriate in the circumstances. The Issuer, each Guarantor and the Holders agree that it would not be just and
equitable if contributions pursuant to this Section 5(d) were to be 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 into account the
equitable considerations referred to herein. The amount paid or payable by an Indemnified Person as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 5(d) shall be deemed to
include, for purposes of this Section 5(d), any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this
Section 5(d), no Holder shall be required to contribute any amount in excess of the amount of discounts and commissions received by such Holder with respect to the Securities. 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 as provided in this Section 5(d) are several in
proportion to their respective purchase obligations and not joint. Notwithstanding the foregoing, none of the Constant Contact Guarantors shall have any rights or obligations pursuant to this Section 5(d) until such time as each of the Constant
Contact Guarantors shall have executed and delivered the Registration Rights Agreement Joinder. 
 (e) 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. 

(f) 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 the Market Maker or any Holder or any Person controlling any Initial Purchaser, the Market Maker or any Holder, or by or on
behalf of the Issuer or the Guarantors or the officers or directors of or any Person controlling the Issuer 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) No Inconsistent Agreements. The Issuer 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 Issuer or any Guarantor, as applicable, under any other agreement and
(ii) neither the Issuer 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. 

  
 22 








 (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 Issuer 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 6 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 in writing and executed by each of the parties hereto. 
 (c) Notices. All notices and other
communications provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, facsimile, or any courier guaranteeing overnight delivery (i) if to a Holder, at the most current address given by such
Holder to the Issuer by means of a notice given in accordance with the provisions of this Section 6(c), which address initially is, with respect to each Initial Purchaser, its address set forth in the Purchase Agreement; (ii) if to the
Issuer and the Guarantors, initially at the Issuer’s 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; five Business Days after being deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged, if sent by facsimile; and on the next Business
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 Issuer 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.  

  
 23 








 (e) Third Party Beneficiaries. Each Holder shall be a third party beneficiary to
the agreements made hereunder between the Issuer 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 two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  

(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. THE VALIDITY AND INTERPRETATION OF THIS
AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY THEREIN, WITHOUT GIVING EFFECT TO ANY PROVISIONS
THEREOF RELATING TO CONFLICTS OF LAW.  
 (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 Issuer, the Guarantors and the Initial Purchasers shall endeavor in good faith negotiations to replace the invalid, void or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to
that of the invalid, void or unenforceable provisions.
