ATTACHMENT A

JOHN HANCOCK FUNDS

EVALUATION BY EACH BOARD OF NEW FORM OF ADVISORY AGREEMENT

At its meeting on December 8-9, 2008, each Board, including all the Independent Trustees, approved the proposed new form of Advisory Agreement for the Funds under Proposal ___.

Each Board, including the Independent Trustees, is responsible for selecting a Fund’s investment adviser, approving the Adviser’s selection of Fund subadvisers and approving that Fund’s advisory and subadvisory agreements, their periodic continuation and any amendments.

Consistent with SEC rules, a Board regularly evaluates a Fund’s advisory and subadvisory arrangements, including consideration of the factors listed below. A Board may also consider other factors (including conditions and trends prevailing generally in the economy, the securities markets and the industry) and does not treat any single factor as determinative, and each Trustee may attribute different weights to different factors. Each Board is furnished with an analysis of its fiduciary obligations in connection with its evaluation and, throughout the evaluation process, a Board is assisted by counsel for a Trust and the Independent Trustees are also separately assisted by independent legal counsel. The factors considered by a Board are:

• the nature, extent and quality of the services to be provided by the Adviser to the Funds;
• the investment performance of the Funds;
• the extent to which economies of scale would be realized as a Fund grows and whether fee levels reflect these economies of scale for the benefit of shareholders of the Fund;
• the costs of the services to be provided and the profits to be realized by the Adviser (including any subadvisers affiliated with the Adviser) and its affiliates from the Adviser’s relationship with a Fund; and
• comparative services rendered and comparative advisory fee rates.

Each Board believes that information relating to all these factors is relevant to its evaluation of a Fund’s advisory agreements.

June 2008 Meeting

At its meeting on June 10, 2008, the Board approved the annual continuation of the Advisory Agreements and considered each of the factors listed above. With respect to each Fund, a discussion of the basis of the Board’s approval of the Advisory Agreements and its consideration of such factors at that meeting is available in the shareholder report for the fiscal six month period during which the approval took place. Each such report was mailed to shareholders of the relevant Fund on or about two months after the relevant six month period. A copy of the report may be obtained by calling 1-800-225-5291 (TDD – 1-800-554-6713) or by writing to the Trust at 601 Congress Street, Boston, Massachusetts 02210, Attn.: Gordon M. Shone, and is also available on the Internet at jhfunds.com.

In evaluating the advisory agreements at its meeting on June 10, 2008, the Board reviewed a broad range of information requested for this purpose. This information included:

(i)      the investment performance of each Fund relative to a category of relevant funds (the Category) and a peer group of comparable funds (the Peer Group). The funds within each Category and Peer Group were selected by Morningstar Inc. (Morningstar), an independent provider of

A-1

	investment company data. Data typically covered the period since each Fund’s inception through December 31, 2007;
(ii)	advisory and other fees incurred by, and the expense ratios of, each Fund relative to a Category and a Peer Group;
(iii)	the advisory fees of comparable portfolios of other clients of the Adviser;
(iv)	the Adviser’s financial results and condition, including its and certain of its affiliates’ profitability from services performed for the Funds;
(v)	breakpoints in each Fund’s and the Peer Group’s fees, and information about economies of scale;
(vi)	the Adviser’s record of compliance with applicable laws and regulations, with the Fund’s investment policies and restrictions, and with the applicable Code of Ethics, and the structure and responsibilities of the Adviser’s compliance department;
(vii)	the background and experience of senior management and investment professionals; and
(viii)	the nature, cost and character of advisory and non-investment management services provided by the Adviser and its affiliates.

The key factors considered by the Board and the conclusions reached are described below.

Nature, extent and quality of services

The Board considered the ability of the Adviser, based on its resources, reputation and other attributes, to attract and retain qualified investment professionals, including research, advisory, and supervisory personnel. The Board considered the investment philosophy, research and investment decision-making processes of the Adviser. The Board considered the Adviser’s execution of its oversight responsibilities. The Board further considered the culture of compliance, resources dedicated to compliance, compliance programs and compliance records of the Adviser. In addition, the Board took into account the non-advisory services provided to the Fund by the Adviser and its affiliates.

Based on the above factors, together with those referenced below, the Board concluded that, within the context of its full deliberations, the nature, extent and quality of the investment advisory services provided to the Fund by the Adviser supported renewal of the advisory agreements.

Fund performance

The Board considered each Fund’s performance results in comparison to the performance of the Category, as well as the Fund’s Peer Group and benchmark index. The Board reviewed the methodology used by Morningstar to select the funds in the Category and the Peer Group.

The Board concluded that each Fund’s investment process and particular investments seemed consistent with the Fund’s investment objectives, strategy and style.

Investment advisory fee rates and expenses

The Board reviewed and considered the contractual investment advisory fee rate payable by each Fund to the Adviser for investment advisory services in comparison to the advisory fees for the Peer Group.

The Board received and considered expense information regarding each Fund’s various components, including advisory fees, distribution and fees other than advisory and distribution fees, including transfer

A-2

agent fees, custodian fees, and other miscellaneous fees (e.g., fees for accounting and legal services). The Board considered comparisons of these expenses to the Peer Group median. The Board also received and considered expense information regarding each Fund’s total operating expense ratio and net expense ratio after waivers and reimbursements. With respect to certain Funds, the Board favorably considered the impact of fee waivers towards ultimately lowering the Funds’ total operating expense ratios.

The Adviser also discussed the Morningstar data and rankings, and other relevant information, for each Fund. Based on the above-referenced considerations and other factors, the Board concluded that the Fund’s overall expenses supported the re-approval of the advisory agreements.

Profitability

The Board received and considered a detailed profitability analysis of the Adviser based on the advisory agreements, as well as on other relationships between the Funds and the Adviser and its affiliates. The Board also considered a comparison of the Adviser’s profitability to that of other similar investment advisers whose profitability information is publicly available. The Board concluded that, in light of the costs of providing investment management and other services to the Funds, the profits and other ancillary benefits reported by the Adviser were not unreasonable.

Economies of scale

The Board received and considered general information regarding economies of scale with respect to the management of each Fund, including the Fund’s ability to appropriately benefit from economies of scale under the Fund’s fee structure. The Board recognized the inherent limitations of any analysis of economies of scale, stemming largely from the Board’s understanding that most of the Adviser’s costs are not specific to individual Funds, but rather are incurred across a variety of products and services.

Information about services to other clients

The Board also received information about the nature, extent and quality of services and fee rates offered by the Adviser to their other clients, including other registered investment companies, institutional investors and separate accounts. The Board concluded that each Fund’s advisory fees were not unreasonable, taking into account fee rates offered to others by the Adviser, after giving effect to differences in services.

Other benefits to the Adviser

The Board received information regarding potential “fall-out” or ancillary benefits received by the Adviser and its affiliates as a result of their relationship with the Funds. Such benefits could include, among others, benefits directly attributable to the relationship of the Adviser with the Fund and benefits potentially derived from an increase in business of the Adviser as a result of their relationship with the Fund (such as the ability to market to shareholders other financial products offered by the Adviser and its affiliates).

The Board also considered the effectiveness of the Adviser’s and the Funds’ policies and procedures for complying with the requirements of the federal securities laws, including those relating to best execution of portfolio transactions and brokerage allocation.

Other factors and broader review

As discussed above, the Board reviewed detailed materials received from the Adviser as part of the annual re-approval process. The Board also regularly reviews and assesses the quality of the services that the Fund receives throughout the year. In this regard, the Board reviews reports of the Adviser at least quarterly, which include, among other things, fund performance reports and compliance reports.

A-3

In addition, the Board meets with portfolio managers and senior investment officers at various times throughout the year.

December 2008 Meeting

In approving the proposed new form of Advisory Agreement at the December 8-9, 2008 meeting, each Board determined that it was appropriate to rely upon its recent consideration at its June 10, 2008 meeting of such factors as: fund performance; the realization of economies of scale; profitability of the Advisory Agreement to the Adviser; and comparative advisory fee rates (as well as its conclusions with respect to those factors). Each Board noted that it had, at the June 10, 2008 meeting, concluded that these factors, taken as a whole, supported the continuation of the Advisory Agreement. Each Board, at the December 8-9, 2008 meeting, revisited particular factors to the extent relevant to the proposed new form of Agreement. In particular, each Board noted the skill and competency of the Adviser in its past management of each Fund’s affairs and subadvisory relationships, the qualifications of the Adviser’s personnel who perform services for each Trust and the Funds, including those who served as officers of each Trust, and the high level and quality of services that the Adviser may reasonably be expected to continue to provide the Funds and concluded that the Adviser may reasonably be expected to perform its services ably under the proposed new form of Advisory Agreement. Each Board also took into consideration the extensive analysis and effort undertaken by a working group comprised of a subset of the Board’s Independent Trustees, which met several times, both with management representatives and separately, to evaluate the proposals described here, prior to the Board’s December 8-9, 2008 meeting. Each Board considered with respect to Proposal ___ the differences between the current Advisory Agreement and proposed new form of Agreement, as described above and agreed that the new Advisory Agreement structure would more clearly delineate the Adviser’s duties under each agreement by separating the Adviser’s non-advisory functions from its advisory functions. The enhanced delineation is expected to facilitate oversight of the Adviser’s advisory and non-advisory activities without leading to any material increase in the Funds’ overall expense ratios.
