Department to verify the Executive’s employment with the Company, and the Company agrees that if such inquiries are so directed, the Company’s Human Resources Department will, upon request, confirm the Executive’s dates of employment
and position held. The Company’s Human Resources Department will also verify the Executive’s salary information and the most recent position held by the Executive with the Company, if the Executive requests disclosure of such information
in writing. 

  

	8.	Non-admission of Wrongdoing.

admission by the Released Parties of any liability or unlawful conduct of any kind. 

  

	 	b.	The parties agree that this Agreement shall not be cited or referred to for any purpose in any grievance, charge, arbitration or administrative, judicial or other
proceeding except a proceeding for enforcement of this Agreement. The parties agree that this Agreement shall not have any precedential value in any grievance, charge, arbitration or administrative, judicial or other proceedings except a proceeding

	9.	Return of Property. Immediately upon the Executive’s execution of this Agreement or at any time the Company otherwise requests, the Executive agrees
to deliver to the Company without copying or reproducing: (1) all documents, files, notes, memoranda, manuals, computer files, computer disks, computer databases, computer programs and/or other storage medium within the Executive’s
possession or control that reflect any trade secrets, proprietary information, privileged information and/or other Confidential Information regarding the Released Parties and/or the Released Parties’ current, former or prospective customers;

within the Executive’s possession or control that is not located on the Executive’s premises. Nothing in this paragraph will prevent the Executive from retaining any documents in his possession or control concerning the employee benefits
and/or compensation the Executive received from the Company. 

  

	10.	Resignations. The Executive shall agree not to accept his appointment as a Director of the Company or Endurance Specialty Insurance Ltd.
(“ESIL”) if re-elected or designated at the Company’s Annual General Meeting of Shareholders on May 10, 2012 (the “Annual General Meeting”) and shall resign from the Boards of Directors of the Company and ESIL effective
immediately following the conclusion of the Annual General Meeting. The Executive shall resign from the position of President of the Company and ESIL and from all other director and officer positions held by the Executive with any other subsidiary
or affiliate of the Company effective May 2, 2012. Receipt of such resignations by the Company shall be a condition precedent to the delivery to the Executive by the Company of any payment or benefit under Sections 1(b) and 1(c).

  

	11.	Compliance with Restrictive Covenants. The Executive’s continued compliance with the restrictive covenants set forth in Sections 3, 4, 5 and 6 shall
be a condition precedent to the receipt by the Executive of the payments and benefits set forth in Sections 1(b) and 1(c) on or after the Severance Date and, in the event the Executive breaches one or more of the covenants set forth in Sections 3 or
4, the Company shall be entitled to recover from the Executive the value of any payment or benefit made or provided by the Company to the Executive pursuant to Sections 1(b) and 1(c) on and after the first date of such breach.

  

	12.	Post-Separation from Service Cooperation. After the Severance Date, the Executive shall reasonably cooperate with the Company to assist with existing or
future investigations, proceedings, litigations or examinations involving the Company or any of its divisions, subsidiaries or affiliates, subject to the Executive’s business schedule and commitments. For each business day, or part
thereof, that the Executive provides assistance as contemplated under this Section 12, the Company shall promptly pay the Executive an amount equal to (i) the Executive’s annual Base Salary as in effect on the date of this Agreement,
divided by (ii) 200. In addition, upon presentment of satisfactory written documentation, the Company will promptly reimburse the Executive for reasonable out-of-pocket travel, lodging and other incidental expenses he incurs in providing such
assistance. If reasonably requested by the Company, the Executive shall make reasonable good faith efforts to travel to such locations as the Company may reasonably request. 

  
 - 10 -

	13.	Obligations of the Executive. The Executive shall have no obligations to the Company under this Agreement after the Severance Date, other than (a) as
provided in Section 12 and (b) to the extent Sections 3, 4, 5 or 6 shall apply. 

  

	14.	Section 280G Treatment. 

  

	 	a.	In the event that any payment or benefit received or to be received by the Executive pursuant to this Agreement or any other plan, arrangement or agreement (all such
payments and benefits being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to any excise tax imposed under Section 4999 (the “Excise Tax”) of the Internal Revenue Code of 1986, as
amended (the “Code”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan, arrangement or agreement, the cash payments under Section 1 shall first
be reduced, and the non-cash payments under Section 1 shall thereafter be reduced, only to the extent necessary to assure that the Executive receives the greater of (i) the amount of such payments under Section 1 that would result in
no portion of the Total Payments being subject to the Excise Tax or (ii) the full amount of such payments under Section 1, after deducting from such payments the effect of the payment by the Executive of the Excise Tax on the Total
Payments. 

  

	 	b.	For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt
or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account, (ii) no portion of the Total
Payments shall be taken into account which, in the opinion of tax counsel (“Tax Counsel”) reasonably acceptable to the Executive and selected by the accounting firm (the “Auditor”) which was the Company’s independent auditor
as of the date of this Agreement, does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no
portion of such Total Payments shall be taken into account which, in the opinion of Tax Counsel, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the base
amount allocable to such reasonable compensation, and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Auditor in accordance with the principles of Sections
280G(d)(3) and (4) of the Code. 

  

	15.	Affirmations. 

  

	 	a.	The Executive affirms that he has not filed, caused to be filed, or presently is a party to any claim, complaint, or action against the Released Parties in any forum or

Party described in this Agreement, including allegations of corporate fraud or (ii) any actual or alleged disability. 

  

	16.	Legal Consultation; Period to Consider and Revoke. The Executive understands that this Agreement is a legally binding document under which he is giving up
certain rights, including any rights he may have under ADEA and OWBPA. As a result, the Company advises the Executive to consult with an attorney of his choosing before he signs this Agreement. The Executive understands that he has been given 21
calendar days from the day he receives this Agreement in which to consider this Agreement. The Executive acknowledges and agrees that he has had an opportunity to consult legal counsel and to inquire into any and all aspects of any claim released
hereunder; that he has had adequate disclosure of all facts necessary to enter into this Agreement and to make a knowing release of any claim released hereby; and that he has executed this Agreement knowingly, without duress and without any
representation, warranty or promise made by the Company or its representatives which is not made in this Agreement. The Executive may revoke this Agreement for a period of seven (7) calendar days following the day he executes this Agreement.
Any revocation within this period must be submitted, in writing, to John V. Del Col, and must state, “I hereby revoke my acceptance of our Severance Agreement and General Release.” The revocation must be either: (a) personally
delivered to Mr. Del Col at Wellesley House, 90 Pitts Bay Road, Pembroke HM08, Bermuda, within 7 calendar days after the Executive signs this Agreement; (b) mailed to Mr. Del Col at the address specified above by First Class United
States mail and postmarked within 7 calendar days after the Executive signs this Agreement or (c) delivered to Mr. Del Col at the address specified above through a reputable overnight delivery service with documented evidence that it was

and signed no sooner than eight (8) days after the Executive dates and signs this Agreement. If the last day of the revocation period is a Saturday, Sunday, or legal holiday in the state in which the Executive was employed on his Severance
Date, then the revocation period shall not expire until the next following day which is not a Saturday, Sunday or legal holiday. The Executive acknowledges that if the Executive does not sign and return this Agreement to the Company or the
Executive signs and revokes this Agreement in accordance with this paragraph, it shall be of no force and effect and the Executive shall have no right to receive, and the Company shall have no obligation to provide the Executive with the
consideration provided herein. If the Executive does not revoke this Agreement pursuant to and in accordance with this paragraph, it shall be effective and enforceable as of the expiration of the revocation period described in this Section

	17.	Assignment. Neither this Agreement nor any right, interest, or obligation hereunder may be assigned (by operation of law or otherwise) by the Executive,
and any attempt to do so will be void. So long as the Executive lives, no person, other than the parties hereto, shall have any rights under or interest in this Agreement or the subject matter hereof. This Agreement shall be binding on, and inure to
the benefit of, the Company and its successors and assigns and any person acquiring, whether by merger, consolidation, purchase of assets or otherwise, all or substantially all of the Company’s assets and business. 

 

	18.	Change. No change or modification of this Agreement shall be valid unless the same is in writing and signed by the parties hereto.

  

	19.	Waiver. No waiver of any provision of this Agreement shall be valid unless in writing and signed by the party waiving its rights. The waiver by either the
Executive or the Company (or its affiliates) of a breach of any provision of this Agreement shall not operate as or be deemed a waiver of any subsequent breach by either the Executive or the Company or relinquishment of the right to insist upon
strict performance of the same condition, promise, agreement or understanding at a future time. 

  

	20.	Remedies. The Executive acknowledges that the Company’s remedy at law for a breach by him of the provisions of Sections 3, 4, 5 or 6 will be
inadequate. Accordingly, in the event of a breach or threatened breach by the Executive of any provision of Sections 3, 4, 5 or 6, the Company shall be entitled to seek injunctive relief (without posting a bond or other security) in addition to any
other remedy it may have. If any of the provisions of, or covenants contained in, Sections 3, 4, 5 or 6 are hereafter construed to be invalid or unenforceable in any jurisdiction, the same shall not affect the remainder of the provisions or the
enforceability thereof in any jurisdiction, which shall be given full effect, without regard to the invalidity or unenforceability in such other jurisdiction. If, at any time of enforcement of Sections 3, 4, 5 or 6, a court or an arbitrator holds
that the restrictions stated herein are unreasonable and/or unenforceable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable and/or enforceable under such circumstances shall be
substituted for the stated period, scope or area and that the court or arbitrator shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law provided, however, that the determination of
such court or arbitrator shall not affect the enforceability of Sections 3, 4, 5 or 6 in any other jurisdiction. This Agreement shall not authorize a court or arbitrator to increase or broaden any of the restrictions in Sections 3, 4, 5 or 6.

  
 - 13 -

	21.	Arbitration. Except as provided in Section 20 above, any controversy, claim or dispute arising out of or relating to this Agreement or breach thereof
which cannot be settled among the parties hereto shall, upon the request of any party involved, be submitted to and finally determined by arbitration in Bermuda with any such dispute or controversy arising under this Agreement being so administered
in accordance with the Arbitration Act 1986. The decision made pursuant thereto shall be conclusive and binding on all parties involved, and any judgment or injunction based upon such decision may be entered in any court having jurisdiction thereof.
Consistent with Section 20 above, the parties hereto shall be entitled to seek injunctive or other equitable relief from any court of competent jurisdiction, without the need to resort to arbitration. 

 

	22.	Invalidity or Unenforceability. The invalidity or unenforceability of any provision of this Agreement will not affect the validity or enforceability of
any other provision of this Agreement, and this Agreement will be construed as if such invalid or unenforceable provision were omitted (but only to the extent that such provision cannot be appropriately reformed or modified). Should any provision of
this Agreement require interpretation or construction, it is agreed by the parties that the entity interpreting or construing this Agreement shall not apply a presumption against one party by reason of the rule of construction that a document is to
be construed more strictly against the party who prepared the document. 

  

	23.	Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be deemed given when (a) delivered
personally or by overnight courier to the following address of the other party hereto (or such other address for such party as shall be specified by notice given pursuant to this Section 23) or (b) sent by facsimile to the following
facsimile number of the other party hereto (or such other facsimile number for such party as shall be specified by notice given pursuant to this Section 23), with the confirmatory copy delivered by overnight courier to the address of such party

	24.	Entire Agreement. This Agreement constitutes the entire agreement between the Executive and the Company and supersedes all prior agreements and
understandings, written or oral, which may have been made by and between the Executive and the Company or its predecessors or affiliates regarding the subject matter of this Agreement, including but not limited to the Amended and Restated Employment
Agreement, dated February 17, 2010, but excluding the Indemnification Agreement, dated February 17, 2010 which is set forth and attached hereto as Exhibit B and which is incorporated herein. 

 

	25.	No Mitigation; No Offset. The Executive shall not be required to mitigate damages or the amount of any payment provided for under this Agreement by
seeking (and, without limiting the generality of this sentence, no payment otherwise required under this Agreement shall be reduced on account of) other employment or otherwise (except Section 1(b)(vi)), and payments under this Agreement shall
not be subject to offset in respect of any claims which the Company may have against the Executive. 

  

	26.	Attorneys’ Fees. Each party to this Agreement will bear its own expenses in connection with any dispute or legal proceeding between the parties
arising out of the subject matter of this Agreement, including any proceeding to enforce any right or provision under this Agreement. 

  

	27.	Compliance with Section 409A. This Agreement is intended to comply with Section 409A of the Code and shall be construed and interpreted in
accordance with such intent. The termination of the Executive’s employment from the Company hereunder constitutes an involuntary separation from service under Section 409A. If any of the payments or benefits specified in Section 1 are
deemed to constitute deferred compensation under Section 409A, such deferred compensation payments or benefits shall not commence until the later of (a) the commencement date otherwise set forth in Section 1 or (b) a date which
is six months after the Severance Date. Furthermore, if the Executive is affected by the six (6) month delay in payment imposed by Section 409A of the Code and this Section 27, the aggregate amount of the first six months of any
installment payments under Section 1 shall be paid at the beginning of the seventh month following the Severance Date and monthly installment payments shall continue thereafter as specified in Section 1. To the extent that the delivery of
any cash or benefits to the Executive under this Agreement, or the payment, settlement or deferral thereof, is otherwise subject to Section 409A of the Code, such cash or benefits shall be paid, settled or deferred in a manner that will comply
with Section 409A of the Code, including regulations or other guidance issued with respect thereto, except as otherwise agreed in writing by the Company and the Executive. 

 

	28.	Counterparts. This Agreement may be signed in two counterparts which may be by facsimile or PDF. 

 

	29.	Headings. The Section headings herein are for convenience of reference only, do not constitute a part of this Agreement and shall not be deemed to limit
or affect any of the provisions hereof. 

  
 - 15 -

	30.	Governing Law. This Agreement shall be construed, interpreted and applied in accordance with the internal laws of Bermuda, without regard to its
principles of conflicts of laws. The Executive submits to the non-exclusive jurisdiction of the courts of Bermuda in respect of matters arising hereunder. 

 

	31.	Acknowledgments.
