     Spire Corporation's By-Laws provide for a minimum of three directors with

Directors has recommended for this Meeting that the number of directors be fixed
at eight and has nominated seven persons for election as directors as noted

Meeting of Stockholders (or Special Meeting in Lieu of Annual Meeting of
Stockholders) and until his successor is duly elected by the stockholders. For

and Committees of the Board" below.

     Unless otherwise instructed, the persons named in the proxy will vote to
fix the number of directors at eight and to elect the seven nominees named below
as directors, leaving one vacancy. Although the Board does not contemplate that
any of the nominees will be unavailable to serve as a director, should any
unexpected vacancies occur, the enclosed proxy will be voted for such
substituted nominees, if any, as may be designated by the Board. In no event
will the proxy be voted for more than seven directors.

                      MEETINGS AND COMMITTEES OF THE BOARD

THE BOARD OF DIRECTORS

     The Board of Directors of the Company held four meetings during 2007. Each
director then serving attended 75% or more of the aggregate of (1) the total
number of Board meetings, and (2) the total number of meetings of the
committee(s) of which he is a member, if any. The Company does not have a
written policy on board attendance at annual meetings of stockholders; however
it does schedule a board meeting immediately after the annual meeting (or
special meeting in lieu thereof) for which members attending receive
compensation. In 2007, all Board Members were present during the Special Meeting
held in Lieu of the 2007 Annual Meeting of Stockholders. The table below
describes the Board's committees.

THE AUDIT COMMITTEE

     The Board of Directors has determined that all members of the Audit
Committee are "independent," as independence for the Audit Committee members is
defined in the listing standards for the Nasdaq Stock Market. The Company's
Board of Directors has determined that Dr. Henseler, Chairman of the Audit
Committee, is an "audit committee financial expert" within the meaning of
applicable regulations of the Securities and Exchange Commission, based on Dr.
Henseler's business experience, as described on Page 1 of this Proxy Statement.
For further information regarding the Audit Committee, see the "Audit Committee
Report" beginning on Page 12 of this Proxy Statement.

THE NOMINATION PROCESS

     The Company does not currently have a standing nominating committee or a
charter for the nomination process. The Company does not have a nominating
committee because it believes that obtaining opinions and advice from all
directors in connection with Board nominations enhances the nomination process.
Nominees for directors are recommended for the Board's selection by a majority
of the independent directors. The Board of Directors has determined that Drs.
Henseler and Magliochetti and Messrs. Lipinski, Mayer and Redmond are
"independent," as independence is defined in the listing standards for the
Nasdaq Stock Market. In March 2005, the Company adopted a Board resolution
addressing the nominations process, which provides substantially as follows:

1.   A majority of the independent directors (the "Majority") shall identify
     individuals believed to be qualified as candidates to serve on the Board
     and shall recommend that the Board select the candidates for all
     directorships to be filled by the Board or by the shareholders at an annual
     or special meeting. In identifying candidates for membership on the Board,
     the Majority shall take into account all factors it considers appropriate,
     which may include strength of character, mature judgment, relevant skills
     and the extent to which the candidate would fill a present need on the
     Board.

                                        3


2.   The Majority shall conduct all necessary and appropriate inquiries into the
     backgrounds and qualifications of possible candidates and, in that
     connection, shall have sole authority to retain any search firm to be used
     to assist it in identifying candidates to serve as directors.

3.   The Majority shall review and make recommendations, as it deems
     appropriate, regarding the size and composition of the Board in order to
     ensure that the Board has the requisite expertise and that its membership
     consists of persons with sufficiently diverse backgrounds. The Majority is
     aware that one member of the Board should meet the criteria for an "audit
     committee financial expert" as defined by SEC rules, and that a majority of
     the members of the Board must be comprised of "independent directors" as
     defined in the rules of the Nasdaq Stock Market. The Majority also believes
     it appropriate for certain members of the Company's management to
     participate as members of the Board.

4.   The Majority will consider candidates for director recommended by
     stockholders of the Company. There are no differences in the manner in
     which the Majority evaluates director nominees recommended by stockholders.
     Stockholders who wish to recommend director candidates should communicate
     names of such candidates, with relevant information on their
     qualifications, to the Secretary, at the address on the first page of this
     Proxy Statement. The Secretary will forward copies of such stockholder
     recommendations to the independent directors for their consideration.

     As indicated above, the independent directors will consider candidates for
director recommended by stockholders of the Company. The procedures for
submitting stockholder recommendations are explained below under "Stockholder
Proposals" beginning on Page 14.

THE COMPENSATION COMMITTEE

     The Compensation Committee of the Board of Directors is composed of three
members, all of whom satisfy the independence standards for Compensation
Committee members under the rules of the Nasdaq Stock Market, and operates under
a written charter. A copy of the Compensation Committee charter is not available
to stockholders on the Company's website. A copy of the Compensation Committee
Charter is attached as APPENDIX A to this Proxy Statement. For 2007, the
Committee was composed of Messrs. Mayer, CHAIRMAN, Lipinski and Redmond. Until
May 2007, Mr. Lipinski was not independent under the rules of the Nasdaq Stock
Market because within the past three years he was an employee of the Company (he
ceased employment with the Company in May 2004). However, the Board of Directors
determined that his membership on the Committee was required by the best
interests of the Company and its shareholders due to his experience with
compensation issues, and complies with the other requirements of the Committee's
charter. Beginning in May 2007, Mr. Lipinski was considered independent.


                     STOCKHOLDER COMMUNICATIONS TO THE BOARD

     Stockholders may contact an individual director, the Board as a group, or a
specified Board committee or group, including the non-employee directors as a
group, by the following means:

     Mail: Spire Corporation
           One Patriots Park
           Bedford, MA  01730-2396
           Attn: Board of Directors

     Each communication should specify the applicable addressee or addressees to
be contacted as well as the general topic of the communication. The Company will
initially receive and process communications before forwarding them to the
addressee. The Company generally will not forward to the directors a stockholder
communication that it determines to be primarily commercial in nature or relates
to an improper or irrelevant topic, or that requests general information about
the Company.


                      COMPLIANCE WITH SECTION 16(A) OF THE
                         SECURITIES EXCHANGE ACT OF 1934

     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors and executive officers, and persons who own more than 10% of a
registered class of the Company's equity securities, to file with the Securities
and Exchange Commission reports of ownership and changes in ownership of common
stock and other equity securities of the

                                        4


Company. Officers, directors and greater than 10% shareholders are required by
SEC regulations to furnish the Company with copies of all Section 16(a) forms
they file.

     Based solely on review of the copies of such reports furnished to the
Company or written or oral representations that no other reports were required,
the Company believes that during 2007, all filing requirements applicable to its
officers, directors and greater than 10% beneficial owners were complied with.


                             OWNERSHIP OF SECURITIES

the Company's directors and the executive officers named in the Summary
Compensation Table under "Compensation of Officers and Directors" and by owners
of more than 5% of the Company's outstanding common stock as of March 3, 2008.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Related Party Transactions
--------------------------

     The Company subleased 77,000 square-feet in a building leased by Mykrolis
Corporation, who in turn leased the building from SPI-Trust, a Trust of which
Mr. Roger G. Little, Chairman of the Board, Chief Executive Officer and
President of the Company, is the sole trustee and principal beneficiary. The
1985 sublease originally was for a period of ten years, was extended for a
five-year period expiring on November 30, 2000 and was further extended for a
five-year period expiring on November 30, 2005. The sublease agreement provided
for minimum rental payments plus annual increases linked to the consumer price
index. Effective December 1, 2005, the Company entered into a two-year Extension
of Lease Agreement (the "Lease Extension") directly with SPI-Trust.

     The Company assumed certain responsibilities of Mykrolis, the tenant under
the former lease, as a result of the Lease Extension including payment of all
building and real estate related expenses associated with the ongoing operations
of the property. The Company will allocate a portion of these expenses to
SPI-Trust based on pre-established formulas utilizing square footage and actual
usage where applicable. These allocated expenses will be invoiced monthly and be
paid utilizing a SPI-Trust escrow account of which the Company has sole
withdrawal authority. SPI-Trust is required to maintain three (3) months of its
anticipated operating costs within this escrow account. On December 1, 2006, the
Company and SPI-Trust amended the Lease Extension to include the lease of an
additional 15,000 square feet from SPI-Trust for a one-year term.

     On November 30, 2007, the Company entered into a new Lease Agreement (the
"New Lease") with SPI-Trust with respect to 144,230 square feet of space
comprising the entire building in which the Company has occupied since December
1, 1985. The term of the New Lease commenced on December 1, 2007 and continues
for five years until November 30, 2012. The Company has the right to extend the
term of the New Lease for an additional five (5) year period. The annual rental
rate for the first year of the New Lease is $12.50 per square foot on a triple
net basis, whereby the tenant is responsible for operating expenses, taxes and
maintenance of the building. The annual rental rate increases on each
anniversary by $0.75 per square foot. If the Company exercises its right to
extend the term of the New Lease, the annual rental rate for the first year of
the extended term will be the greater of (a) the rental rate in effect
immediately preceding the commencement of the extended term or (b) the market
rate at such time, and on each anniversary of the commencement of the extended
term the rental rate will increase by $0.75 per square foot. The Company
believes that the terms of the New Lease are commercially reasonable.

     Rent expense under the New Lease and the Lease Extension, as amended, for
the year ended December 31, 2007 was $1,415,000. In connection with the Lease
Extension, as amended, the Company was invoiced and paid certain SPI-Trust
related expenses, including building maintenance and insurance. The Company
invoiced SPI-Trust on a monthly basis and SPI-Trust reimbursed the Company for
all such costs.

     In conjunction with the May 2003 acquisition of Bandwidth Semiconductor,
LLC (now known as Spire Semiconductor, LLC) by the Company, SPI-Trust, purchased
from Stratos Lightwave, Inc. (Spire Semiconductor's former

                                        7


owner) the building that Spire Semiconductor occupies in Hudson, New Hampshire
for $3.7 million. Subsequently, the Company entered into a lease for the
building (90,000 square feet) with SPI-Trust whereby the Company agreed to pay
$4.1 million to SPI-Trust over an initial five-year term expiring in 2008 with a
Company option to extend for five years. In addition to the rent payments, the
lease obligates the Company to keep on deposit with SPI-Trust the equivalent of
three months rent ($304,000 as of December 31, 2007). The lease agreement does
not provide for a transfer of ownership at any point. Interest costs were
assumed at 7%. For the year ended December 31, 2007, interest expense was
approximately $76,000.

     Edward D. Gagnon, General Manager of the Company's subsidiary, Spire
Semiconductor, LLC, is a son-in-law of Roger G. Little, Chairman of the Board,
Chief Executive Officer and President of the Company. For the year ended
December 31, 2007, Mr. Gagnon received salary and bonus of $160,702, incentive
stock options to purchase 5,000 shares of Spire common stock at an exercise
price of $9.60 per share with a grant date fair value of $29,097 (computed in
accordance with FAS 123(R)), and had value realized of $178,946 from the sale of
Spire common stock acquired through the exercise of incentive stock options.

NON-QUALIFIED DEFERRED COMPENSATION PLAN

     Effective January 1, 2002, the Company adopted the Spire Corporation
Non-Qualified Deferred Compensation Plan (the "Deferred Compensation Plan") for
Mr. Roger G. Little, Chairman of the Board, Chief Executive Officer and
President of the Company. Under the Deferred Compensation Plan, the Company
makes equal monthly contributions to the Spire Corporation Non-Qualified
Deferred Compensation Trust (the "Trust") up to the annually required amount of
$250,000. The Company records these contributions as selling, general and
administrative expense when made. The Trustee makes all investment decisions for
the Trust on behalf of Mr. Little. The Company has not guaranteed a return on
investment for Mr. Little. All earnings and losses on the Deferred Compensation
Plan assets are borne by Mr. Little. All contributions and earnings are fully
vested to Mr. Little when made but are subject to the Company's creditors in the
event of bankruptcy. The Company makes contributions only if it has "available
cash" to meet its operational needs as determined by the Compensation Committee.
If the Compensation Committee determines that there is not enough "available
cash" then it may defer funding for a particular plan year only until cash
becomes available. As of December 31, 2007, the Company has fully funded its
obligations as called for by Mr. Little's employment agreement.

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS

     The Company has an employment agreement with Roger G. Little, Chairman of
the Board, Chief Executive Officer and President. For 2007, he received the
following pursuant to the agreement: a base salary of $243,000, payment under an
annual incentive bonus program of up to 50% of base salary (depending on
attainment of specified performance goals as set by the Compensation Committee),
which amounted to $24,300, and payment under the Deferred Compensation Plan in
the amount of $250,000. For subsequent years, base salary will be no less than
$205,000; and payments under the annual incentive bonus program and the Deferred
Compensation Plan will be determined annually. The agreement also provides for a
Company vehicle for Mr. Little and for life insurance for which he may designate
a beneficiary in the face amount of $500,000. Further, the agreement provides
for the payment of 12 months' base salary in the event he is terminated without
cause or if he terminates the agreement for "good reason." The agreement also
precludes Mr. Little from competing with the Company during his employment and
for a period of one year thereafter, and from disclosing confidential
information. The agreement also entitles Mr. Little to paid vacations in
accordance with the regular policy of the Company for the executive officers.

     If Mr. Little's employment is terminated by the Company without cause or by
Mr. Little for "good reason" within six months prior to a change-of-control or
within one year thereafter, then in lieu of payment of 12 months' base salary,
the Company shall pay Mr. Little in 24 monthly installments a cash severance
amount equal to three times his average annual compensation, including base
salary and bonuses.

     The agreement was originally executed on January 1, 2002 and had a
five-year term. On each anniversary of the agreement, the agreement is
automatically extended for an additional five-year term unless the parties have
renegotiated the agreement or one of the parties has given the other party
notice of non-renewal.

DIRECTORS' COMPENSATION

     Spire Corporation does not pay its directors who are also officers of the
Company any additional compensation for services as directors. In December of
2006, the Compensation Committee engaged Francois Quinson, an independent
consultant, to review the compensation paid to the Company's Board of Directors.
Based upon Mr. Quinson's recommendations, on March 15, 2007, the Compensation
Committee approved the following as elements of compensation for non-employee
directors and the Board of Directors passed a resolution approving the
compensation package. Accordingly, in 2007, the compensation for non-employee
directors included the following:

     o    Cash Board meeting attendance fee of $1,000 per meeting attended in
          person and $500 for each meeting by telephone;

     o    Non-incentive stock options under the 2007 Plan for 2,000 shares for
          each Board meeting attended either in person or by telephone, with the
          awards being for one meeting per quarter and four quarterly meeting
          per year, to a maximum of 8,000 shares per annum. These options vest
          immediately and are considered a long term incentive;

     o    Cash meeting attendance fee of $1,000 for each formal meeting of the
          Audit Committee and of the Compensation Committee attended either in
          person or by telephone, with the payments subject to an annual maximum
          of $5,000 per member of each such committee;

     o    No additional compensation when committee meeting is held in
          conjunction with a Board meeting;

     o    $12,000 annual retainer for all directors, payable quarterly;

     o    $5,000 annual retainer for the Chairman of the Audit Committee,
          payable quarterly;

     o    $4,000 annual retainer for the Chairman of the Compensation Committee,
          payable quarterly;

     o    $2,000 annual retainer for other members of the Audit and Compensation
          Committees, payable quarterly; and

     o    Expense reimbursement for all reasonable expenses incurred in
          attending meetings and tending to Spire business.

     The following table shows non-employee director compensation in 2007:

three directors, all of whom satisfy the independence standards for Audit
Committee members under the rules of the Nasdaq Stock Market, and operates under
a written charter. A copy of the Audit Committee Charter is not available to

composed of Drs. Henseler, CHAIRMAN, and Magliochetti, and Mr. Mayer.

RESPONSIBILITIES

     The responsibilities of the Audit Committee include engaging an accounting
firm to serve as Spire's independent registered public accounting firm.
Management is responsible for Spire's internal controls and financial reporting
process. The independent registered public accounting firm is responsible for
performing an independent audit of Spire's consolidated financial statements in
accordance with the standards of the Public Company Accounting Oversight Board
(PCAOB) and for issuing an opinion thereon. The Audit Committee's responsibility
is to oversee these processes and Spire's internal controls. The Audit Committee
does not prepare or audit the Company's financial statements or certify their
accuracy.

REVIEW WITH MANAGEMENT AND INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

     In this context, the Audit Committee has met and held discussions with
management and the independent registered public accounting firm. Management
represented to the Audit Committee that Spire's consolidated financial
statements were prepared in accordance with generally accepted accounting
principles, and the Audit Committee has reviewed and discussed the audited
consolidated financial statements with management and the independent registered
public accounting firm. The Audit Committee has discussed with the independent
registered public accounting firm the matters required to be discussed by the
statement on Auditing Standards No. 61 as amended, as adopted by the Public
Company Accounting Oversight Board in Rule 3200T.

        Spire's independent registered public accounting firm also provided to
the Audit Committee the written disclosures and the letter required by
Independence Standards Board Standard No. 1, "Independence Discussions with
Audit Committees," and the Audit Committee discussed with the independent
registered public accounting firm, Vitale, Caturano & Company, Ltd., the firm's
independence.

SUMMARY

     Based upon the Audit Committee's discussions with management and the
independent registered public accounting firm and the Audit Committee's review
of Spire's audited consolidated financial statements and the representations of
management, and the report of the independent registered public accounting firm
to the Audit Committee, the Audit

                                       12


Committee recommended that the Board of Directors include the audited
consolidated financial statements in Spire's Annual Report on Form 10-K for the
year ended December 31, 2007, as filed with the Securities and Exchange
Commission.

     ALL OTHER FEES were for services other than the services reported above and

     POLICY ON AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT
SERVICES OF INDEPENDENT AUDITORS

     The Audit Committee pre-approves all audit and permissible non-audit
services provided by the independent registered public accounting firm. These
services may include audit services, audit-related services, tax services and
other services. Pre-approval is generally provided for up to one year, and any
pre-approval is detailed as to the particular service or category of services
and is generally subject to a specific budget. The independent registered public
accounting firm and management are required to periodically report to the Audit
Committee regarding the extent of services provided by the independent
registered public accounting firm in accordance with the pre-approval, and the
fees for the services performed to date. The Audit Committee may also
pre-approve particular services on a case-by-case basis.


                    INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

     The Audit Committee of the Board of Directors of Spire Corporation has
engaged Vitale, Caturano & Company, Ltd. as the Company's independent registered
public accountants for the current fiscal year. They have served as accountants
for the Company since January 7, 2004.

     As the Company's independent registered public accountants, Vitale,
Caturano & Company, Ltd. was engaged to conduct quarterly reviews of the
Company; to conduct an audit of the consolidated financial statements of the
Company for the full year 2007; and to prepare the federal and state tax returns
of the Company for the year ended December 31, 2007. Representatives of Vitale,
Caturano & Company, Ltd. are expected to attend the Meeting in order to respond
to questions from stockholders and will have the opportunity to make a
statement.

                                       13


                        PROXIES AND VOTING AT THE MEETING

     Each signed and returned proxy will be voted in accordance with any
instructions of the stockholder(s) executing the proxy. A proxy signed without
instructions will be voted in accordance with the Board's recommendations. If a
stockholder attends the Meeting and votes in person, his or her proxy will not
be counted. A signed proxy may be revoked at any time before it is exercised,
either in person or by giving written notice of revocation to the Secretary of
the Company at the address on the first page of this Proxy Statement.

     Each share of common stock is entitled to one vote on all matters submitted
to the stockholders for approval. No vote may be taken unless a quorum (I.E., a
majority of the common stock issued, outstanding, and entitled to vote) is
present at the Meeting in person or by proxy. The seven nominees for election as
directors at the Meeting who receive the greatest number of votes properly cast
for the election of directors shall be elected the directors of the Company. The
approval of any other matter as may properly come before the meeting requires
the affirmative vote of a majority in interest of the stock represented and
entitled to vote at the meeting. Broker non-votes are counted for purposes of
determining the presence of a quorum, but are not counted for purposes of
determining the result of any vote. Abstentions are counted in determining the
presence of a quorum and have the effect of a vote against a proposal.

     The Board has fixed March 28, 2008, as the record date for determining the
stockholders entitled to vote at the Meeting. On that date there were 8,328,688
shares of common stock issued, outstanding, and entitled to vote.


                                  OTHER MATTERS

     The Board knows of no other matters that may come before the Meeting. If
any other matters should properly come before the Meeting, it is the intention
of the persons named in the accompanying proxy to vote in accordance with their
judgment on such matters. Such discretionary authority is conferred by the
proxy.

     All costs of this solicitation, which is being made principally by mail,
but which may be supplemented by telephone or personal contacts by the Company's
directors, officers, and employees without additional compensation, will be
borne by the Company. Brokers will be requested to forward proxy soliciting
material to the beneficial owners of the stock held in such brokers' names, and
the Company will reimburse them for their expenses incurred in complying with
the Company's request.

     In the Company's filings with the SEC, information is sometimes
"incorporated by reference". This means that the Company is referring you to
information that has previously been filed with the SEC, so the information
should be considered as part of the filing you are reading. Based on SEC
regulations, the Audit Committee Report specifically is not incorporated by
reference into any other filings with the SEC.

     The Company's policy is to encourage its Board members to attend the Annual
Meeting of Stockholders, and all of the members standing for re-election
attended the Special Meeting in Lieu of the 2007 Annual Meeting of Stockholders.

2009 Annual Meeting of Stockholders pursuant to Exchange Act Rule 14a-8,

                                       FOR
                                SPIRE CORPORATION
                       (Version Adopted on March 18, 2008)

PURPOSE

     The purpose of the Compensation Committee (the "Committee") shall be to
discharge the responsibilities of the Board of Directors relating to the
Company's compensation programs and compensation of the Company's executives.

COMPOSITION

     The Committee shall consist of two or more members of the Board of
Directors, each of whom is determined by the Board of Directors to be
"independent" under the rules of the Nasdaq Stock Market and the Sarbanes-Oxley
Act.

     Under exceptional and limited circumstances, however, one director who is
not independent as defined in the rules and regulations of the Nasdaq Stock
Market and who is not a current employee or an immediate family member of an
employee of the Company may serve as a member of the Committee, provided that:

     1. The Board determines that membership by the individual on the Committee
is required by the best interests of the Company and its shareholders;

     2. The Company complies with all other requirements of the rules and
regulations of the Nasdaq Stock Market with respect to non-independent members
of the Committee, as such rules and regulations may be amended or supplemented
from time to time; and

     3. No such person may serve on the Committee for more than two years.

APPOINTMENT AND REMOVAL

     The members of the Committee shall be appointed by the Board of Directors
and shall serve until each such member's successor is duly elected and qualified
or until such member's earlier resignation or removal. The members of the
Committee may be removed, with or without cause, by a majority vote of the Board
of Directors.

CHAIRMAN

     Unless a Chairman is elected by the full Board of Directors, the members of
the Committee shall designate a Chairman by majority vote of the full Committee
membership. The Chairman will chair all regular sessions of the Committee and
set the agendas for Committee meetings.

DELEGATION TO SUBCOMMITTEES

     In fulfilling its responsibilities, the Committee shall be entitled to
delegate any or all of its responsibilities to a subcommittee of the Committee.

MEETINGS

     The Committee shall meet as frequently as circumstances dictate. The
Chairman of the Board or any member of the Committee may call meetings of the
Committee.

     As part of its review and establishment of the performance criteria and
compensation of designated key executives, the Committee should meet separately
at least on an annual basis with the chief executive officer and any other
corporate officers, as it deems appropriate. However, the Committee should also
meet from time to time without such officers present, and in all cases, such
officers shall not be present at meetings at which their performance and
compensation are being discussed and determined. All meetings of the Committee
may be held telephonically.

                                       A-1


     All non-management directors who are not members of the Committee may
attend meetings of the Committee, but may not vote. In addition, the Committee
may invite to its meetings any director, member of management of the Company,
and such other persons, as it deems appropriate in order to carry out its
responsibilities. The Committee may also exclude from its meetings any persons
it deems appropriate in order to carry out its responsibilities.

DUTIES AND RESPONSIBILITIES

     The Committee shall carry out the duties and responsibilities set forth
below. These functions should serve as a guide with the understanding that the
Committee may determine to carry out additional functions and adopt additional
policies and procedures as may be appropriate in light of changing business,
legislative, regulatory, legal, or other conditions. The Committee shall also
carry out any other responsibilities and duties delegated to it by the Board of
Directors from time to time related to the purposes of the Committee outlined in
this Charter.

     In discharging its oversight role, the Committee is empowered to study or
investigate any matter of interest or concern that the Committee deems
appropriate and shall have the sole authority to retain, without seeking Board
approval, outside counsel or other experts for this purpose, including the
authority to approve the fees payable to such counsel or experts and any other
terms of retention.

evaluation, review and approve the annual salary, bonus, stock options, and
other benefits, direct and indirect, of the chief executive officer and other
executive officers.

     4. In determining the long-term incentive component of compensation for the
chief executive officer and other executive officers, the Committee should
consider the Company's performance and relative shareholder return, the value of
similar incentive awards to chief executive officer and other executive officers
at comparable companies, and the awards given to the Company's chief executive
officer and other executive officers in past years. The Committee is not
precluded from approving awards (with the ratification of the Board of
Directors) as may be required to comply with applicable tax laws, such as Rule
162(m).

          c. Establish and periodically review policies for the administration
of executive compensation programs; and

          d. Take steps to modify any executive compensation program that yields
payments and benefits that are not reasonably related to executive and corporate
performance.

     6. Establish and periodically review policies in the area of senior
management perquisites.

     7. Consider policies and procedures pertaining to expense accounts of
senior executives.

     8. Review and recommend to the full Board of Directors compensation of
directors as well as directors and officers' indemnification and insurance

officers of the Company, including consulting arrangements, employment

                                       A-2


contracts, change-in-control, severance, or termination arrangements, and loans
to employees made or guaranteed by the Company.

MONITORING INCENTIVE AND EQUITY-BASED COMPENSATION PLANS

     10. Review and make recommendations to the Board of Directors with respect
to the Company's incentive-compensation plans and equity-based plans, and review
the activities of the individuals responsible for administering those plans.

     11. Review and approve all equity compensation plans of the Company that
are not otherwise subject to the approval of the Company's shareholders.

     12. Review and make recommendations to the full Board of Directors, or
approve, all awards of shares or share options pursuant to the Company's
equity-based plans.

     13. Monitor compliance by executives with the rules and guidelines of the
Company's equity-based plans.

     14. Review and monitor employee pension, profit sharing, and benefit plans.

Committee. In that connection, in the event the Committee retains a compensation
consultant, the Committee shall have the sole authority to approve such
consultant's fees and other retention terms.

REPORTS

     17. Report regularly to the Board of Directors with respect to matters that
are relevant to the Committee's discharge of its responsibilities and with
respect to such recommendations as the Committee may deem appropriate. The
report to the Board of Directors may take the form of an oral report by the
Chairman or any other member of the Committee designated by the Committee to
make such report.

     18. To the extent applicable to the Company, review and discuss with the
Company's management the Compensation Discussion and Analysis ("CD&A") required
by the rules and regulations of the Securities and Exchange Commission (the
"SEC") and determine whether to recommend to the Board of Directors that the
CD&A be included in the Company's annual proxy statement or annual report on
Form 10-K in accordance with the applicable rules and regulations of the SEC.

     19. To the extent applicable to the Company, produce a "Compensation
Committee Report" for inclusion in the Company's annual proxy statement or
annual report on Form 10-K in accordance with the applicable rules and
regulations of the SEC.

     20. Maintain minutes or other records of meetings and activities of the
Committee.

                                       B-1

APPOINTMENT AND REMOVAL

     The members of the Committee shall be appointed by the Board of Directors
and shall serve until such member's successor is duly elected and qualified or
until such member's earlier resignation or removal. The members of the Committee

Directors.

CHAIRMAN

     Unless a Chairman is elected by the full Board of Directors, the members of
the Committee shall designate a Chairman by the majority vote of the full
Committee membership. The Chairman will chair all regular sessions of the
Committee and set the agendas for Committee meetings.

DELEGATION TO SUBCOMMITTEES

     In fulfilling its responsibilities, the Committee shall be entitled to
delegate any or all of its responsibilities to a subcommittee of the Committee.

MEETINGS

     The Committee shall meet as frequently as circumstances dictate. As part of
its goal to foster open communication, the Committee shall periodically meet
separately with each of management and the independent auditors to discuss any
matters that the Committee or management or the auditors believe would be
appropriate to discuss privately. In addition, the Committee should meet with
the independent auditors and management periodically to review the Company's
financial statements in a manner consistent with that outlined in this Charter.
The Chairman of the Board or any member of the Committee may call meetings of
the Committee. All meetings of the Committee may be held telephonically.

     All non-management directors who are not members of the Committee may
attend meetings of the Committee, but may not vote. In addition, the Committee
may invite to its meetings any director, member of management of the Company,
and such other persons, as it deems appropriate in order to carry out its
responsibilities. The Committee may also exclude from its meetings any persons
it deems appropriate in order to carry out its responsibilities.

DUTIES AND RESPONSIBILITIES

     The Committee shall carry out the duties and responsibilities set forth
below. These functions should serve as a guide with the understanding that the
Committee may determine to carry out additional functions and adopt additional
policies and procedures as may be appropriate in light of changing business,
legislative, regulatory, legal, or other conditions. The Committee shall also
carry out any other duties and responsibilities delegated to it by the Board of
Directors from time to time related to the purposes of the Committee outlined in
this Charter. The Committee may perform any functions it deems appropriate under
applicable law, rules, or regulations, the Company's By-laws, and the
resolutions or other directives of the Board, including review of any
certification required to be reviewed in accordance with applicable law or
regulations of the SEC.

     In discharging its oversight role, the Committee is empowered to study or
investigate any matter of interest or concern that the Committee deems
appropriate. In this regard, the Committee shall have the authority to retain,
without seeking Board approval, outside legal, accounting, or other advisors for
this purpose, including the authority to approve the fees payable to such
advisors and any other terms of retention.

     The Committee shall be given full access to the Company's Board of
Directors, corporate executives, and independent accountants as necessary to
carry out these responsibilities. While acting within the scope of its stated
purpose, the Committee shall have all the authority of the Board of Directors,
except as otherwise limited by applicable law.

                                       B-2


     Notwithstanding the foregoing, the Committee is not responsible for
certifying the Company's financial statements or guaranteeing the auditors'
report. The fundamental responsibility for the Company's financial statements
and disclosures rests with management and the independent auditors. It also is
the job of the chief executive officer and senior management rather than that of
the Committee to assess and manage the Company's exposure to risk.

DOCUMENTS/REPORTS REVIEW

     1. Discuss with management and the independent auditors prior to public
dissemination the Company's annual audited financial statements and quarterly
financial statements, including the Company's disclosures under "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
discuss with the independent auditors the matters required to be discussed by
Statement of Auditing Standards No. 61.

     2. Discuss with management and the independent auditors prior to the
Company's filing of any quarterly or annual report:

          a. Whether any significant deficiencies in the design or operation of
internal controls exist that could adversely affect the Company's ability to
record, process, summarize, and report financial data;

          b. The existence of any material weaknesses in the Company's internal
controls; and

          c. The existence of any fraud, whether or not material, that involves
management or other employees who have a significant role in the Company's
internal controls.

     3. Discuss with management and the independent auditors the Company's
earnings press releases (paying particular attention to the use of any "pro
forma" or "adjusted" non-GAAP information), as well as financial information and
earnings guidance provided to analysts and rating agencies. The Committee's
discussion in this regard may be general in nature (I.E., discussion of the
types of information to be disclosed and the type of presentation to be made)
and need not take place in advance of each earnings release or each instance in
which the Company may provide earnings guidance.

     4. Discuss with management and the independent auditors the Company's major
financial risk exposures, the guidelines and policies by which risk assessment
and management is undertaken, and the steps management has taken to monitor and
control risk exposure.

INDEPENDENT AUDITORS

     5. Retain and terminate independent auditors and have the sole authority to
approve all audit engagement fees and terms as well as all non-audit engagements
with the independent auditors.

     6. Inform each public accounting firm performing work for the Company that
such firm shall report directly to the Committee.

     7. Oversee the work of any public accounting firm employed by the Company,
including the resolution of any disagreement between management and the auditor
regarding financial reporting, for the purpose of preparing or issuing an audit
report or related work.

     8. Approve in advance any significant audit or non-audit engagement or
relationship between the Company and the independent auditors, other than
"prohibited non-auditing services," as may be specified in the Sarbanes-Oxley
Act of 2002 or applicable laws or regulations.

     9. Review, at least annually, the qualifications, performance, and
independence of the independent auditors. In conducting its review and
evaluation, the Committee should:

          a. At least annually obtain and review a report by the Company's
independent auditors describing: (i) the auditing firm's internal
quality-control procedures; (ii) any material issues raised by the most recent
internal quality-control review, or peer review, of the auditing firm, or by any
inquiry or investigation by governmental or professional authorities, within the
preceding five years, respecting one or more independent audits carried out by
the auditing firm, and any steps

                                       B-3


taken to deal with any such issues; and (iii) to assess the auditors'
independence, all relationships between the independent auditors and the
Company;

          b. Ensure the rotation of the lead audit partner at least every five
years, and consider whether there should be regular rotation of the audit firm
itself;

          c. Confirm with any independent auditors retained to provide audit
services for any fiscal year that the lead (or coordinating) audit partner
(having primary responsibility for the audit), or the audit partner responsible
for reviewing the audit, has not performed audit services for the Company in
each of the five previous fiscal years of the Company; and

          d. Take into account the opinions of management and the Company's
internal auditors (or other personnel responsible for the internal audit
function).

FINANCIAL REPORTING PROCESS

     10. In consultation with the independent auditors, management, and the
internal auditors, review the integrity of the Company's financial reporting
processes, both internal and external. In that connection, the Committee should
obtain and discuss with management and the independent auditors reports from
management and the independent auditors regarding:

          a. All critical accounting policies and practices to be used by the
Company and the related disclosure of those critical accounting policies under
"Management's Discussion and Analysis of Financial Condition and Results of
Operations";

          b. Analyses prepared by management and/or the independent auditors
setting forth significant financial reporting issues and judgments made in
connection with the preparation of the financial statements, including all
alternative treatments of financial information within generally accepted
accounting principles that have been discussed with the Company's management,
the ramifications of the use of the alternative disclosures, and treatments, and
the treatment preferred by the independent auditors;

          c. Major issues regarding accounting principles and financial
statement presentations, including any significant changes in the Company's
selection or application of accounting principles;

          d. Major issues as to the adequacy of the Company's internal controls
and any specific audit steps adopted in light of material control deficiencies;

          e. Issues with respect to the design and effectiveness of the
Company's disclosure controls and procedures, management's evaluation of those
controls and procedures, and any issues relating to such controls and procedures
during the most recent reporting period;

          f. The effect of regulatory and accounting initiatives as well as
off-balance sheet structures on the financial statements of the Company; and

          g. Any other material written communications between the independent
auditor and the Company's management.

     11. Review periodically the effect of regulatory and accounting
initiatives, as well as off-balance sheet structures, on the financial
statements of the Company.

     12. Review with the independent auditors any audit problems or difficulties
encountered and management's response thereto. In this regard, the Committee
must regularly review with the independent auditors:

                a. Any audit problems or other difficulties encountered by the
auditors in the course of the audit work, including any restrictions on the
scope of the independent auditors' activities or on access to requested
information, and any significant disagreements with management; and

                b. Management's responses to such matters. Without excluding
other possibilities, the Committee may wish to review with the independent
auditors: (i) any accounting adjustments that were noted or proposed by the
auditors

                                       B-4


but were "passed" (as immaterial or otherwise), (ii) any communications between
the audit team and the audit firm's national office respecting auditing or
accounting issues presented by the engagement, and (iii) any "management" or
"internal control" letter issued, or proposed to be issued, by the independent
auditors to the Company.

     13. Review and discuss with the independent auditors the responsibilities,
budget, and staffing of the Company's internal audit function.

LEGAL COMPLIANCE/GENERAL

     14. Review periodically, with the Company's counsel, any legal matter that
could have a significant impact on the Company's financial statements.

     15. Discuss with management and the independent auditors the Company's
guidelines and policies with respect to risk assessment and risk management. The
Committee should discuss the Company's major financial risk exposures and the
steps management has taken to monitor and control such exposures.

     16. Set clear hiring policies for employees or former employees of the
independent auditors. At a minimum, these policies should provide that any
public accounting firm may not provide audit services to the Company if the
chief executive officer, controller, chief financial officer, chief accounting
officer, or any person serving in an equivalent position for the Company was
employed by the public accounting firm and participated in any capacity in the
audit of the Company within one year of the initiation of the current audit.

     17. Establish procedures for (a) the receipt, retention, and treatment of
complaints received by the Company regarding accounting, internal accounting
controls, or auditing matters; and (b) the confidential, anonymous submission by
employees of the Company of concerns regarding questionable accounting or
auditing matters.

     18. Review all related party transactions for potential conflict of
interest situations on an ongoing basis. All such transactions must be approved
by the Committee.

     19. Prepare all reports required to be included in the Company's proxy
statement, pursuant to and in accordance with applicable rules and regulations
of the SEC.

     20. Report regularly to the full Board of Directors. In this regard, the
Committee should review with the full board any issues that arise with respect
to the quality or integrity of the Company's financial statements, the Company's
compliance with legal or regulatory requirements, and the performance and
independence of the Company's independent auditors.

     21. The Committee shall provide such recommendations, as the Committee may
deem appropriate. The report to the Board of Directors may take the form of an
oral report by the Chairman or any other member of the Committee designated by
the Committee to make such report.

     22. Review and assess the adequacy of this Charter annually and recommend
to the Board and amendments or modifications to the Charter that the Committee
deems appropriate.

     23. Maintain minutes or other records of meetings and activities of the
Committee.

LIMITATION OF AUDIT COMMITTEE'S ROLE

     With respect to the foregoing responsibilities and processes, the Committee
recognizes that the Company's financial management, as well as the independent
auditors has more time, knowledge, and detailed information regarding the
Company than do Committee members. Consequently, in discharging its oversight
responsibilities, the Committee will not provide or be deemed to provide any
