Exhibit 99.3

March 3, 2010

Dear Max business partners

It is my great pleasure to share with you exciting news for Max and its business partners. Max Capital Group Ltd. and Harbor Point Limited have agreed to combine through a merger of equals. As you will see in the attached press release and presentation, we believe the combination will bring many benefits to all our stakeholders after its expected close in the second quarter of 2010.

In recognition of the truly transformational nature of this merger, the combined company will be branded as Alterra Capital Holdings Limited upon closing, and operating companies will be rebranded accordingly. Alterra means “high ground,” and we believe this is a fitting name for a company that will be a provider of superior security and a market leader. Alterra will trade under the symbol ALTE with approximately $3 billion of equity and with minimal financial leverage.

As you know, Max is already a profitable, dynamic and growing company. We have effectively expanded our operations in recent years with the Max Specialty start-up, the acquisition of Max at Lloyd’s and the establishment of Max Latin America, as well as numerous smaller initiatives. Nevertheless, we believe there are advantages to being an even larger player in today’s property and casualty markets, where financial size is often considered a proxy for security and sustainability.

Harbor Point writes both short- and long-tail reinsurance business, principally from offices in Bermuda and Bernardsville, New Jersey. In Harbor Point we have a partner that brings a great deal to the table — a very well-regarded and profitable Bermuda reinsurance company with complementary operations, a robust balance sheet and shareholders’ equity of $1.9 billion. Importantly, there is little overlap between our businesses, and we expect to bring the operations together quickly and with minimal disruption. We believe this development will be beneficial to our business partners. Alterra will be committed to continuing, without interruption, to provide the same level of superior service that you have come to expect as partners of Max. In virtually all cases, you will be able to access the services of Alterra through your existing Max service providers. Until the transaction closes, however, Max and Harbor Point will continue to operate independently.

I am sure you will have numerous questions, many of which will be answered in the attached press release and presentation. As detailed in the press release, a joint investors’ conference call will be held at 8:00 am EST on March 4, 2010 and will be webcast at maxcapgroup.com. If you have additional queries, please refer to your normal contacts at Max.

I am very excited about the prospects for Alterra, a company that will have a superior foundation and be well positioned to provide enhanced security and an even broader product range to our clients and business partners in the future. I look forward to continuing our productive working relationship.
