ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.
Agreement and Plan of Amalgamation
Alterra Capital Holdings Limited ("Alterra") announced on December 19, 2012
that, on December 18, 2012, it had entered into an Agreement and Plan of Merger
(the "Merger Agreement ") with Markel Corporation ("Markel") and Commonwealth
Merger Subsidiary Limited, a direct wholly owned subsidiary of Markel ("Merger
Sub "), pursuant to which, subject to the terms and conditions set forth
therein, Merger Sub will merge with and into Alterra (the "Merger"), with
Alterra as the surviving company (the "Surviving Company ") becoming a wholly
owned subsidiary of Markel. A copy of the joint press release of Alterra and
Markel issued on December 19, 2012, announcing the entry into the Merger
Agreement is attached as Exhibit 99.1 and is incorporated by reference herein.
Pursuant to the Merger Agreement, upon the closing of the Merger, each issued
and outstanding Alterra common share (other than any Alterra common shares with
respect to which appraisal rights have been duly exercised under Bermuda law),
will automatically be converted into the right to receive (a) 0.04315 validly
issued, fully paid and nonassessable shares of Markel voting common stock,
without par value (the "Exchange Ratio"), together with any cash paid in lieu of
fractional shares, and (b) $10.00 in cash, without interest (the "Cash
Consideration" and together with the Exchange Ratio, the "Merger
Consideration"). The Merger Agreement is governed by Bermuda law and subject to
the jurisdiction of Bermuda courts. The Merger will be a taxable event for
Alterra shareholders.
Each of the boards of directors of Alterra and Markel unanimously adopted and
approved the Merger Agreement, and deemed it fair to, advisable and in the best
interests of, their respective companies and shareholders to enter into the
Merger Agreement and to consummate the Merger and the other transactions
contemplated thereby. In Markel's case, this includes (among other things) the
issuance of Markel common stock in connection with the Merger. Markel must
obtain the approval of at least a majority of votes cast at a special meeting of
Markel's shareholders in accordance with the rules of the New York Stock
Exchange to authorize the issuance of Markel common stock in the Merger. Under
the Merger Agreement, Alterra's board of directors approved an amendment to
Alterra's bye-laws which would reduce the shareholder vote required to approve a
merger with any other company from the affirmative vote of three-fourths of the
votes cast at a general meeting of the shareholders to a simple majority (the
"Bye-law Amendment"), and recommended that Alterra's shareholders approve the
Bye-law Amendment. If the Bye-law Amendment is approved by Alterra's
shareholders, then Alterra must obtain approval of at least a majority of the
votes cast at a special general meeting of Alterra's shareholders to approve and
adopt the Merger Agreement and the Merger (a "Alterra Special General Meeting").
If the Bye-law Amendment is not approved, then Alterra must obtain approval of
at least three-fourths of the votes cast at a Alterra Special General Meeting.

The Merger is expected to close in first half of 2013, subject to customary
closing conditions, including among others, (i) receiving the required approvals
of Alterra and Markel shareholders, (ii) authorization having been obtained for
listing the Markel common stock to be issued and reserved for issuance to
Alterra shareholders in the Merger on the New York Stock Exchange, (iii) receipt
of required regulatory approvals, including those from applicable insurance
authorities, (iv) effectiveness of the registration statement for the Markel
common stock to be issued in the Merger and (v) the absence of any order or
injunction by a court of competent jurisdiction preventing the consummation of
the Merger, and the absence of any action taken, or any law enacted, entered,
enforced or made applicable to the Merger, by any governmental entity that makes
the consummation of the Merger illegal or otherwise restrains, enjoins or
prohibits the Merger. The parties' obligations to consummate the Merger are also
subject to the condition that A.M. Best Company, Inc. ("A.M. Best") shall have
provided oral or written notice to the parties that certain of Markel's and
Alterra's insurance subsidiaries have been assigned a Financial Strength Rating
of at least "A" on a group basis, after giving effect to the Merger or will be
assigned such rating immediately after the effective time of the Merger (the
"A.M. Best Condition"). In addition, Alterra's obligation to consummate the
Merger is conditioned on the addition of two Alterra nominees to Markel's board
of directors as described in more detail below, and Markel's obligation to
consummate the Merger is conditioned on Alterra having not less than
$500,000,000 in immediately available unrestricted funds on the closing date of
the Merger.
--------------------------------------------------------------------------------
All options to purchase Alterra common shares that are outstanding and
unexercised will automatically be converted into options to acquire a number of
Markel common stock adjusted on an exchange ratio equal to the sum of the
Exchange Ratio plus the quotient of $10.00 divided by the weighted average share
price of Markel common stock for the five consecutive trading days immediately
preceding the second trading day before the closing of the Merger (the
"Incentive Award Exchange Ratio"), at an equitably adjusted exercise price and
otherwise on the same terms and conditions.
Awards of restricted Alterra common shares which automatically vest upon a
change of control will automatically vest upon the closing of the Merger
(generally restricted Alterra common shares granted on or before December 31,
2010, other than performance based awards) and holders of such Alterra
restricted common shares will receive the Merger Consideration, plus any other
amounts payable under the terms of the corresponding grant upon the exercise of
such restricted Alterra common shares. Awards of restricted Alterra common
shares that do not automatically vest upon a change of control (generally
restricted Alterra common shares granted after January 1, 2011 or performance
based awards of restricted Alterra common shares granted on or before
December 31, 2010) will automatically be converted into the right to receive
similarly restricted Markel common stock based on an exchange ratio equal to the
Incentive Award Exchange Ratio and otherwise on the same terms and conditions.

Holders of warrants to purchase Alterra common shares that are outstanding and
unexercised ("Alterra Warrants") will have the option to either (i) surrender
the warrant to Markel for an amount equal to the Merger Consideration multiplied
by the number of Alterra common shares the holder of such warrant would have
received had such holder exercised such warrant immediately prior to
effectiveness of the Merger through a cashless exercise, plus any other amounts
payable under the terms of the warrant upon its exercise, or (ii) have such
Alterra Warrant remain outstanding in accordance with its terms. Upon the
effective time of the Merger, such Alterra warrants (such warrants, the

ITEM 5.02 Departure of Directors or certain Officers; Election of Directions;
Appointment of Certain Officers; Compensatory Arrangements of Certain
Officers
In connection with the proposed Merger, on December 18, 2012, Alterra adopted a
change in control severance plan, which will provide severance payments and
benefits to eligible employees of Alterra and its subsidiaries, including
Alterra's executive officers, in connection with certain terminations of
employment (the "Change in Control Severance Plan"). The Change in Control
--------------------------------------------------------------------------------
Severance Plan was unanimously approved by Alterra's board of directors. Under
the Change in Control Severance Plan, in the event that an employee's employment
is terminated without cause or the employee resigns for good reason, in each
case, within twelve (12) months following a change in control (a "Qualifying
Event"), the employee would be entitled to severance consisting of continued
base salary and health benefits at active employee rates for a minimum of six
(6) weeks and a maximum of fifty-two (52) weeks, based on the employee's years
of service and position with Alterra, and a pro-rated bonus for the year in
which the Qualifying Event occurs. The severance payments are payable in a lump
sum if the employee is entitled to twelve (12) weeks or less of continued base
salary.
For purposes of the Change in Control Severance Plan, the completion of the
Merger will constitute a change in control. An employee will not be entitled to
severance benefits under the Change in Control Severance Plan if the employee's
employment is terminated for any reason other than a Qualifying Event,
including, without limitation, (i) by the employer for cause, (ii) by the
employee without good reason or (iii) due to the employee's death or
disability. An employee's entitlement to payments and benefits under the plan is
subject to the employee's execution and non-revocation of a general release of
claims against the employer and its affiliates. In the event that the employee
is party to an employment agreement with Alterra that provides severance, the
employee will only be provided with severance payments and benefits under the
Change in Control Severance Plan to the extent they are greater than those
provided under such employment agreement.

In addition, on December 18, 2012, Alterra's board of directors unanimously
approved the establishment of a pool in respect of retention awards with an
aggregate award amount equal to approximately $23.6 million. Employees of
Alterra, including executive officers, will generally be eligible to receive
cash retention awards from this pool. However, individual award amounts, if any,
for employees, including executive officers, have not yet been determined. The
retention awards will be paid in cash on the first anniversary of the completion
of the Merger, subject to the recipient's continued service with Markel on such
date. In the event that a recipient's employment is terminated without cause or
due to the recipient's death or disability or the recipient's resignation for
good reason prior to such first anniversary date, the recipient or the
recipient's estate will receive the retention award upon such termination. In
the event that a recipient's employment is terminated for cause, by reason of
the recipient's voluntary resignation without good reason or retirement prior to
such first anniversary date, or the Merger is not consummated for any reason,
the recipient's retention award will be forfeited.
Alterra has previously granted certain performance share awards to employees in
2010 and 2012, including Alterra's named executive officers W. Marston Becker,
Joseph W. Roberts, Peter A. Minton, Thomas C. Wafer and D. Andrew Cook. On
December 18, 2012, in connection with the Merger, for purposes of determining
the number of Alterra's common shares deliverable upon vesting of the
performance share awards (other than certain performance share awards granted to
employees in Brazil), the compensation committee of Alterra's board of directors
has determined, subject to the completion of the Merger, that the
performance-based vesting criteria has been satisfied to the maximum extent
possible. The time-based vesting criteria applicable to the performance share
awards remain unchanged
ITEM 8.01 OTHER EVENTS.
(a) On December 19, 2012, Alterra and Markel issued a joint press release
announcing the execution of the Merger Agreement. A copy of the joint press
release is attached hereto as Exhibit 99.1 and is incorporated by reference
herein.
(b) In connection with the announcement of the Merger Agreement, Alterra is
filing as Exhibit 99.2 to this Current Report on Form 8-K the materials being
used in connection with presentations to and conversations with investors
beginning the date hereof.
(c) Alterra's initial estimate for losses from Hurricane Sandy is in the range
of $90 million to $120 million, before tax and net of reinsurance and
reinstatement premiums. This estimate is within Alterra's normal risk tolerances
for natural catastrophe events in the Mid-Atlantic and Northeastern United
States.
Alterra's loss estimates are based on proprietary modeling analyses, industry
assessments of exposure, claims information obtained from Alterra's clients and
brokers to date, and a review of in-force contracts. Alterra's actual losses
from these events may vary materially from the estimates due to the inherent
uncertainties in making such determinations resulting from several factors,
including the preliminary nature of available information, the potential
inaccuracies and inadequacies in the data provided by clients and brokers, the
modeling techniques employed and the application of such techniques, the
contingent nature of business interruption exposures, the effects of any
resultant demand surge on claims activity, and attendant coverage issues. In
addition, actual losses may increase if Alterra's reinsurers fail to meet their
obligations to Alterra or the reinsurance protections purchased by Alterra are
exhausted or are otherwise unavailable.
