day of October, 2000 (the "Effective Date"), between HCC INSURANCE HOLDINGS,
INC. (the "Company" or "HCC"), and CHRISTOPHER L. MARTIN ("Executive"),
sometimes collectively referred to herein as the "Parties."

                                    RECITALS:

         WHEREAS, Executive is to be employed by the Company, and, as an
integral part of its management, to participate in the decision-making process
relative to short and long-term planning and policy for the Company;

         WHEREAS, it is the desire of the Company to directly engage Executive
as an officer of the Company, and

         WHEREAS, Executive is desirous of committing himself to serve the
Company on the terms herein provided.

         NOW, THEREFORE, in consideration of the foregoing and of the respective
covenants and agreements set forth below, the Parties agree as follows:

         1. TERM. The Company hereby agrees to employ Executive as Vice
President and General Counsel, and Executive hereby agrees to accept such
employment, on the terms and conditions set forth herein, for the period
commencing on the Effective Date and expiring as of 11:59 p.m. on December 31,
2003 (the "Basic Term") (unless sooner terminated as hereinafter set forth).
Subject to the terms of this Agreement, Executive agrees that he shall perform
his duties at the corporate home office of the Company, wherever that may be
located as determined from time to time by the Company.

               (a) DUTIES AS EMPLOYEE OF THE COMPANY. Executive shall, subject
          to the supervision of the Chief Executive Officer of the Company and
          the Executive Management Committee of HCC ("Executive Committee"),

          reasonably incident to the responsibilities incident to Executive's
          title. During normal business hours, Executive shall devote his full
          time and attention to diligently attending to the business of the
          Company. Executive shall not directly or indirectly render any
          services of a business, commercial, or professional nature to any
          other person, firm, corporation, or organization, whether for

          Chairman of the Board of HCC. However, Executive shall have the right
          to engage in such activities as may be appropriate in order to manage
          his personal investments so long as such activities do not materially
          interfere or conflict with the performance of his duties to the
          Company hereunder. The conduct of such activity shall not be deemed to

          materially interfere or conflict with Executive's performance of his
          duties until Executive has been notified in writing thereof and given
          a reasonable period in which to cure the same.

               (b) OTHER DUTIES. If elected, Executive agrees to serve on any
          Committee of HCC and in one or more executive offices of any of HCC's
          direct or indirect subsidiaries (the "Subsidiaries"), provided
          Executive is indemnified for serving in any and all such capacities in
          a manner acceptable to the Company and Executive. If elected,
          Executive agrees that he shall not be entitled to receive any
          compensation for serving in any capacity for the Subsidiaries other
          than the compensation to be paid to Executive by the Company pursuant
          to this Agreement.

         3. COMPENSATION AND RELATED MATTERS.

               (a) BASE SALARY. Executive shall receive a base salary paid by
          the Company at the annual rate of $170,000, during the period

          Company: all options to purchase stock of HCC being granted in the
          sole and absolute discretion of HCC and subject to the Executive's
          execution of option agreements in a form acceptable to the Executive
          Committee.

               (d) EXPENSES. During the Basic Term, Executive shall be entitled
          to receive prompt reimbursement for all reasonable expenses incurred
          by him in accordance with the policies and procedures established by
          the Executive Committee for the Company's senior executive officers in

          arrangement. Nothing paid to Executive under any plan or arrangement

               has been delivered to Executive written notice from HCC's
               Executive Committee, supplying the particulars of Executive's
               acts or omissions that the Executive Committee, believes
               constitute Cause, a reasonable period of time (not less than 30
               days) has been given to Executive after such notice to either
               cure the same or to meet with the Executive Committee, on behalf

               Executive being unable to perform the essential functions of his
               position, with or without reasonable accommodation.

                    (3) A "GOOD REASON" shall mean any of the following (without
               Executive's express written consent):

                         (i) A failure by HCC to continue in effect any employee
                    benefit plan in which Executive was participating, or the
                    taking of any action by HCC that would adversely affect
                    Executive's participation in, or materially reduce
                    Executive's benefits under, any such employee benefit plan,
                    unless such failure or such taking of any action adversely
                    affects the employees of HCC generally to the same extent;

                         (ii) Any material breach by the Company of any
                    provision of this Agreement.

                         (iii) Following a Change of Control, but only if within

                    alteration in the nature and status of Executive's title,
                    duties or responsibilities, or the assignment of duties or
                    responsibilities inconsistent with Executive's status,
                    title, duties and responsibilities;

                         (iv) A relocation of the Company's principal executive
                    offices, or of Executive's relocation to any place other
                    than the principal executive offices, exceeding a distance
                    of fifty (50) miles from the Company's current executive
                    office located in Houston, Texas, except for reasonably
                    required travel by Executive on the Company's business; and

                         (v) Any failure by the Company to obtain the assumption
                    and performance of this Agreement by any successor (by
                    merger, consolidation, or otherwise) or assign of the

                  specified matter only if such matter is not corrected by HCC
                  within thirty (30) days of its receipt of written notice of
                  such matter from Executive, and in no event shall a

                  eighty (180) days following the date of the event described
                  above or in the case of a Change of Control, 180 days
                  following the Change of Control be a termination for Good
                  Reason due to such event.

                    securities under an employee benefit plan of the Company
                    becomes the "beneficial owner" (as defined in Rule l3d-3
                    under the Securities Exchange Act of 1934), directly or
                    indirectly, of 50% or more of the Company's then outstanding
                    voting common stock; or

                         (ii) At any time during the period of three (3)
                    consecutive years (not including any period prior to the
                    date hereof), individuals who at the beginning of such
                    period constituted the Board (and any new director whose
                    election by the Board or whose nomination for election by

                    least two-thirds of the directors then still in office who
                    either were directors at the beginning of such period or
                    whose election or nomination for election was previously so
                    approved) cease for any reason to constitute a majority
                    thereof; or

                         (iii) The shareholders of the Company approve a merger
                    or consolidation of the Company with any other corporation,
                    other than a merger or consolidation (a) in which a majority
                    of the directors of the surviving entity were directors of
                    the Company prior to such consolidation or merger, and (b)
                    which would result in the voting securities of the Company
                    outstanding immediately prior thereto continuing to
                    represent (either by remaining outstanding or by being
                    changed into voting securities of the surviving entity) more
                    than 50% of the combined voting power of the voting
                    securities of the surviving entity outstanding immediately
                    after such merger or consolidation; or

                         (iv) The shareholders approve a plan of complete
                    liquidation of the Company or an agreement for the sale or
                    disposition by the Company of all or substantially all of
                    the Company's assets.

          other stock-related grants ("Stock Awards") which Executive has
          received under any of the HCC stock plans shall vest immediately and
          shall be exercisable for thirty (30) days from the date of such
          Termination Event or the remainder of their term, whichever is less.

               (3) All accrued compensation and unreimbursed expenses through

     Other Benefits through the date of death. Such amounts shall be paid to
     Executive's estate or beneficiary, as applicable, in a lump sum in cash
     within ninety (90) business days after the date of death. Additionally,

     the Company, he will immediately tender his resignation from any and all
     Board of Director positions held with the Company and/or any of its
     Subsidiaries and affiliates.

         5. NON-COMPETITION, NON-SOLICITATION, AND CONFIDENTIALITY. Executive

          (b) CONFLICTS OF INTEREST. Executive agrees that while employed by the

     inform the President of the Company as to each offer received by Executive
     to engage in any such activity. Executive further agrees to disclose to the
     Company any other facts of which Executive becomes aware which might in
     Executive's good faith judgment reasonably be expected to involve or give
     rise to a Conflict of Interest or potential Conflict of Interest.

     (3) months thereafter, engage in or contribute Executive's knowledge to any
     work which is competitive with or similar to a product, process, apparatus,
     service, or development on which Executive worked or with respect to which
     Executive had access to Confidential Information while employed by the
     Company. Following the expiration of said two (2) year period, Executive
     shall continue to be obligated under the Confidential Information paragraph
     of this Agreement not to use or to disclose Confidential Information of the
     Company or its affiliates and Subsidiaries so long as it shall not be
     publicly available. It is understood that the geographical area set forth
     in this covenant is divisible so that if this clause is invalid or
     unenforceable in an included geographic area, that area is severable and
     the clause remains in effect for the remaining included geographic areas in
     which the clause is valid.

          (d) NON-SOLICITATION OF CUSTOMERS. Executive further agrees that for a
     period of two (2) years after the termination of his employment with the
     Company and any of its affiliates and Subsidiaries, he will not solicit or
     accept any business from any customer or client or prospective customer or
     client with whom Executive dealt or solicited while employed by Company
     during the last twelve (12) months of his employment.

          (e) NON-SOLICITATION OF EMPLOYEES. Executive agrees that for a period
     of two (2) years after the termination of his employment with the Company
     and any of its affiliates and Subsidiaries, he will not either directly or
     indirectly, on his own behalf or on behalf of others, solicit, attempt to
     hire, or hire any person employed by Company to work for Executive or for
     another entity, firm, corporation, or individual.

          (f) CONFIDENTIAL INFORMATION. Executive further agrees that he will
     not, except as the Company may otherwise consent or direct in writing,
     reveal or disclose, sell, use, lecture upon, publish or otherwise disclose
     to any third party any Confidential Information or proprietary information
     of the Company or its affiliates and Subsidiaries, or authorize anyone else
     to do these things at any time either during or subsequent to his
     employment with the Company. This Paragraph shall continue in full force
     and effect after termination of Executive's employment and after the
     termination of this Agreement. Executive's obligations under this Paragraph
     with respect to any specific Confidential Information and proprietary
     information shall cease when that specific portion of the Confidential
     Information and proprietary information becomes publicly known, in its
     entirety and without combining portions of such information obtained
     separately. It is understood that such Confidential Information and
     proprietary information of the Company and its affiliates and Subsidiaries
     include matters that Executive conceives or develops, as well as matters
     Executive learns from other employees of Company or its affiliates and
     Subsidiaries. Confidential Information is defined to include information:
     (1) disclosed to or known by the Executive as a consequence of or through
     his employment with the Company; (2) not generally known outside the
     Company and its affiliates and Subsidiaries; and (3) which relates to any
     aspect of the Company and its

EMPLOYMENT AGREEMENT - PAGE 8

<PAGE>

     affiliates or their business, finances, operation plans, budgets, research,
     or strategic development. "Confidential Information" includes, but is not
     limited to the Company's and its affiliates' and Subsidiaries' trade
     secrets, proprietary information, financial documents, long range plans,
     customer lists, employer compensation, marketing strategy, data bases,
     costing data, computer software developed by the Company or its affiliates,
     investments made by the Company or its affiliates, and any information
     provided to the Company or its affiliates by a third party under
     restrictions against disclosure or use by the Company or others.

          (g) RETURN OF DOCUMENTS, EQUIPMENT, ETC. All writings, records, and
     other documents and things comprising, containing, describing, discussing,
     explaining, or evidencing any Confidential Information, and all equipment,
     components, parts, tools, and the like in Executive's custody or possession
     that have been obtained or prepared in the course of Executive's employment
     with the Company shall be the exclusive property of the Company, shall not
     be copied and/or removed from the premises of the Company, except in
     pursuit of the business of the Company, and shall be delivered to the
     Company, without Executive retaining any copies, upon notification of the
     termination of Executive's employment or at any other time requested by the
     Company. The Company shall have the right to retain, access, and inspect
     all property of Executive of any kind in the office, work area, and on the
     premises of the Company upon termination of Executive's employment and at
     any time during employment by the Company to ensure compliance with the
     terms of this Agreement.

          (h) REAFFIRM OBLIGATIONS. Upon termination of his employment with the
     Company, Executive, if requested by Company, shall reaffirm in writing
     Executive's recognition of the importance of maintaining the
     confidentiality of the Company's Confidential Information and proprietary
     information, and reaffirm any other obligations set forth in this
     Agreement.

          (i) PRIOR DISCLOSURE. Executive represents and warrants that he has
     not used or disclosed any Confidential Information he may have obtained
     from Company or its affiliates prior to signing this Agreement, in any way
     inconsistent with the provisions of this Agreement.

          (j) CONFIDENTIAL INFORMATION OF PRIOR COMPANIES. Executive will not
     disclose or use during the period of his employment with the Company any
     proprietary or Confidential Information or Copyright Works which Executive
     may have acquired because of employment with an employer other than the
     Company or acquired from any other third party, whether such information is
     in Executive's memory or embodied in a writing or other physical form.

          (k) BREACH. Executive agrees that any breach of Paragraphs 5(a), (c),
     (d), (e) or above cannot be remedied solely by money damages, and that in
     addition to any other remedies Company or its affiliates may have, the
     Company shall be entitled to obtain injunctive relief against Executive.
     Nothing herein, however, shall be construed as limiting the Company's right
     to pursue any other available remedy at law or in equity,

EMPLOYMENT AGREEMENT - PAGE 9

<PAGE>

     including recovery of damages and termination of this Agreement and/or any
     payments that may be due pursuant to this Agreement.

          (l) RIGHT TO ENTER AGREEMENT. Executive represents and covenants to
     the Company that he has full power and authority to enter into this
     Agreement and that the execution of this Agreement will not breach or
     constitute a default of any other agreement or contract to which he is a
     party or by which he is bound.

          (m) EXTENSION OF POST-EMPLOYMENT RESTRICTIONS. In the event Executive
     breaches Paragraphs 5(b), (d), or (e) above, the restrictive time periods
     contained in those provisions will be extended by the period of time
     Executive was in violation of such provisions.

          (n) ENFORCEABILITY. The agreements contained in Section 5 are
     independent of the other agreements contained herein. Accordingly, failure
     of the Company to comply with any of its obligations outside of this
     Paragraph do not excuse Executive from complying with the agreements
     contained herein.

          (o) SURVIVABILITY. The agreements contained in Paragraphs 5(c) through
     (g) shall survive the termination of this Agreement for any reason.

         6. ASSIGNMENT. This Agreement cannot be assigned by Executive. The
Company may assign this Agreement only to a successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and assets of the Company provided such
successor expressly agrees in writing reasonably satisfactory to Executive to
assume and perform this Agreement in the same manner and to the same extent that
the Company would be required to perform it if no such succession and assignment
had taken place. Failure of the Company to obtain such written agreement prior
to the effectiveness of any such succession shall be a material breach of this
Agreement.

         7. BINDING AGREEMENT. Executive understands that his obligations under
this Agreement are binding upon Executive's heirs, successors, personal
representatives, and legal representatives.

         8. NOTICES. All notices pursuant to this Agreement shall be in writing
and sent certified mail, return receipt requested, addressed as set forth below,
or by delivering the same in person to such party, or by transmission by
facsimile to the number set forth below. Notice deposited in the United States

available under this Agreement.

arbitration. The arbitration shall be conducted in accordance with the National

Association ("AAA"). If the Parties cannot agree on an arbitrator, a list of

arbitration will be shared equally by Executive and Company. Arbitration of such
disputes is mandatory and in lieu of any and all civil causes of action and
lawsuits either party may have against the other arising out of Executive's
employment with Company, or separation therefrom. Such arbitration shall be held
in Houston, Texas.

         WHEREAS, Executive has entered into an Employment Agreement dated as of
the 1st day of October, 2000; and

         WHEREAS, it is the desire of the Company and the Executive to amend the

shall be amended by deleting in its entirety subparagraph (ii).

         3. The provisions of Paragraphs (4)(c) and 4(d) shall be deleted in
their entirety and replaced with the following:

              (c)  TERMINATION IN EVENT OF DEATH: BENEFITS. If Executive's
employment is terminated by reason of Executive's death during the Basic Term,
