Management's discussion of fund performance

MANAGED BY

Michael A. Foreman, Long Hoang, Daniel A. Walker, Henry Wong, and Ying Yi

As the fourth quarter closes, economic conditions in the U.S. have seemingly improved. Fears of a deep recession have diminished while inflation and interest rates have declined. The job market remains resilient with 216,000 jobs added in December, much higher than the consensus estimate of 170,000. For the year, 2023 job gains were 2.7 million, or a monthly average of 225,000, down from 4.8 million, or 399,000 a month, in 2022. The unemployment rate remains at 3.7%. The Fed did not increase the Fed Funds rate during the fourth quarter with the last increase occurring in July. Treasury yields increased through the end of October, then began a steady decline. Commercial real estate sales activity during the year remained slow.

Demand for industrial real estate remains strong, but growth in rental rates has slowed as an abundance of new supply has been delivered to the market. Multifamily demand also remains strong, but rental rates plateaued and even decreased in some markets, as new apartment completions came online. Retail demand is strong, with less than 5% availability overall, fueled by minimal new construction and favorable consumer spending trends. Grocery-anchored centers continue to be the strongest performers. Traditional office demand remains weak, negatively impacted by low demand due to the hybrid work environment and high capital costs. Overall, office values have significantly decreased. Typically, "A" quality buildings with top amenities packages are garnering the most demand, while demand for medical office and healthcare real estate remains strong.

The debt market remains challenged, as lending standards have tightened although there was an increase in activity in December as interest rates declined during the quarter. Debt remains available but is more expensive with higher interest rates as compared to 2022. As such, debt demand remains short-term, and prepayment flexibility is sought by most borrowers. Maturing loans with lower interest rates will face refinancing challenges and increased equity requirements as values have decreased. Office loans in particular face the biggest challenge, as most lenders have pulled back on traditional office lending. However, medical office and life sciences financing is still available. Industrial and multifamily remain the most desired property types for financing, with retail, particularly grocer anchored centers, also favored.

The investment objective of the fund is to generate current income, and to a lesser extent, capital appreciation. The fund returned 7.68% for the year ended December 31, 2023 due to a stable income stream and strong capital growth compared to 2022.

The views expressed in this report are exclusively those of Manulife Investment Management Private Markets (US) LLC, and are subject to change. They are not meant as investment advice. Please note that the holdings discussed in this report, if any, may not have been held by the fund for the entire period.

Notes to financial statements 12-31-23

1. Organization

John Hancock GA Mortgage Trust (the fund) is a Delaware statutory trust that is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a closed-end management investment company. The investment objective of the fund is to generate current income and to a lesser extent, capital appreciation.

The fund is only offered to "accredited investors" within the meaning of Regulation D under the Securities Act of 1933 (the 1933 Act), non-U.S. investors within the meaning of Regulation S under the 1933 Act, and other investors eligible to invest in a private placement.

2. Significant accounting policies

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (US GAAP), which require management to make certain estimates and assumptions as of the date of the financial statements. Actual results could differ from those estimates and those differences could be significant. The fund qualifies as an investment company under Topic 946 of Accounting Standards Codification of US GAAP.

Events or transactions occurring after the end of the fiscal period through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the fund:

Security valuation. Investments are valued at the end of each month at a minimum. The fund invests primarily in mortgage loans that do not have readily ascertainable market prices. Manulife Investment Management Private Markets (US) LLC (the Advisor), assisted by its Pricing Committee (composed of officers of the Advisor and its affiliates), determines the fair value of the fund's securities that are not publicly traded or whose market prices are not readily available pursuant to procedures established by the Advisor and adopted by the Board of Trustees. In connection with that determination, portfolio valuations will be prepared in accordance with the Advisor's valuation policy using proprietary models. In certain instances, valuations may be obtained from independent valuation firms.

Valuation techniques include net present value and discounted cash flow models, comparison with similar instruments for which observable market prices exist and other valuation models. Assumptions and inputs used in valuation techniques include risk-free and benchmark interest rates, credit spreads and other inputs used in estimating discount rates.

For mortgage investments, the fund uses proprietary valuation models, which are developed from recognized US GAAP valuation approaches under ASC 820. Some or all of the significant inputs into these models may be unobservable and are derived either from observable market prices or rates or are estimated based on unobservable assumptions. Valuation models that employ significant unobservable inputs require a higher degree of management judgment and estimation in the determination of fair value. Management judgment and estimation are usually required for the selection of the appropriate valuation model to be used, determination of expected future cash flows on the financial instrument being valued, determination of the probability of counterparty default and prepayments and selection of appropriate discount rates.

The fund uses a three-tier hierarchy to prioritize the pricing assumptions, referred to as inputs, used in valuation techniques to measure fair value. Level 1 includes securities valued using quoted prices in active markets for identical securities. Level 2 includes securities valued using other significant observable inputs. Observable inputs may include quoted prices for similar securities, interest rates, prepayment speeds and credit risk. Prices for securities valued using these inputs are received from independent pricing vendors and brokers and are based on an evaluation of the inputs described. Level 3 includes securities valued using significant unobservable inputs when market prices are not readily available or reliable, including the Advisor's own assumptions in determining the fair value of investments. Factors used in determining value

16

John Hancock GA Mortgage Trust

Notes to financial statements 12-31-23

may include market or issuer specific events or trends, changes in interest rates and credit quality. The inputs or methodology used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. Changes in valuation techniques and related inputs may result in transfers into or out of an assigned level within the disclosure hierarchy.

Mortgage investments are measured at fair value based on the present value of the expected cash flows of the mortgage. There are no quoted prices in active markets. Assumptions and inputs used in the valuation of mortgage investments include prepayment estimates, determination of the discount rate based on the risk-free interest rate adjusted for credit risk (including estimation of probability of default), liquidity and any other adjustments that the manager believes that a third-party market participant would take into account in pricing a transaction. Mortgage investment valuations rely primarily on the use of significant unobservable inputs, including credit assumptions, which require significant judgment and, accordingly, are classified as Level 3.

Other debt obligations are typically valued based on the evaluated prices provided by an independent pricing vendor. Independent pricing vendors utilize matrix pricing which takes into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data, as well as broker supplied prices. Other debt obligations are generally classified as Level 2.

Investments in open-end mutual funds are valued at their respective net asset values each business day and are generally classified as Level 1.

The following is a summary of the values by input classification of the fund's investments as of December 31, 2023 by major security category or type:

			Level 2	Level 3
	Total		Significant	Significant
	value at	Level 1	observable	unobservable
	12-31-23	quoted price	inputs	inputs
Investments in securities:

Commercial mortgage loans	$1,870,450,746	—	—	$1,870,450,746

Short-term investments	88,123,670	$61,987,363	26,136,307	—
Total investments in securities	$1,997,379,322	$61,987,363	$64,941,213	$1,870,450,746

The following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value. There were no transfers into or out of Level 3 during the period.

	Fair Value		Significant

loans

*A weighted average is an average in which each input in the grouping is assigned a weighting before summing to a single average value. The weighting of the input is determined based on a security's fair value as a percentage of the total fair value.

A change to unobservable inputs of the fund's Level 3 securities as of December 31, 2023 could have resulted in changes to the fair value measurement, as follows:

	Impact to Valuation	Impact to Valuation
Significant Unobservable Input	if input had increased	if input had decreased
Discount rate	Decrease	Increase

Due to the inherent uncertainty of determining the fair value of Level 3 investments, the fair value of the investments may differ significantly from the values that would have been used had a ready market for such securities existed and may differ materially from the values that may ultimately be received or settled. Further, such investments will generally be subject to legal and other restrictions, or otherwise will be less liquid than publicly traded instruments. If the fund is required to liquidate a portfolio investment in a forced or liquidation sale, the fund might realize significantly less than the value at which such investment will have been previously been recorded. The fund's investments will be subject to market risk. Market risk is the potential for changes in the value due to market changes. Market risk is directly impacted by the volatility and liquidity in the markets in which the investments are traded.

Commercial mortgage loans. The fund invests in commercial mortgage loans, and to a lesser extent, mezzanine loans and B-notes (to the extent permitted by the fund's investment restrictions), which are secured by multifamily, commercial or other properties and are subject to risks of delinquency and foreclosure and risks of loss. Commercial real estate loans are generally not fully amortizing, which means that they may have a significant principal balance or balloon payment due on maturity. Full satisfaction of the balloon payment by a commercial borrower is heavily dependent on the availability of subsequent financing or a functioning sales market, as well as other factors such as the value of the property, the level of prevailing mortgage rates, the borrower's equity in the property and the financial condition and operating history of the property and the borrower. In certain situations, and during periods of credit distress, the unavailability of real estate financing may lead to default by a commercial borrower. In addition, in the absence of any such takeout financing, the ability of a borrower to repay a loan secured by an income-producing property will depend upon the successful operation of such property rather than upon the existence of independent income or assets of the borrower. If the net operating income of the property is reduced, the borrower's ability to repay the loan may be impaired. Furthermore, the fund may not have the same access to information in connection with investments in commercial mortgage loans, either when investigating a potential investment or after making an investment, as compared to publicly traded securities.

Commercial mortgage loans are usually non-recourse in nature. Therefore, if a commercial borrower defaults on the commercial loan, then the options for financial recovery are limited in nature. To the extent the underlying default rates with respect to the pool or tranche of commercial real estate loans in which the fund directly or indirectly invests increase, the performance of the fund investments related thereto may be adversely affected. Default rates and losses on commercial loans will be affected by a number of factors, including global, regional and local economic conditions in the area where the properties are located, the borrower's equity in the underlying property and/or assets and the financial circumstances of the borrower. A decline in specific real estate or credit markets may result in higher delinquencies and defaults. In the event of default, the lender will have no right to assets beyond collateral attached to the commercial mortgage

18

Notes to financial statements 12-31-23

loan. In certain instances, a negotiated settlement or an amendment to the terms of the commercial loan are the only options before an ultimate foreclosure on the commercial property. A foreclosure is costly and often protracted by litigation and bankruptcy restrictions. The ultimate disposition of a foreclosed property may also yield a price insufficient to cover the cost of the foreclosure process and the balance attached to the defaulted commercial loan.

In the event of any default under a mortgage or real estate loan held directly by the fund, it will bear a risk of loss of principal to the extent of any deficiency between the value of the collateral and the principal and accrued interest of the mortgage or real estate loan, which could have a material adverse effect on the profitability of the fund. In the event of the bankruptcy of a mortgage or real estate loan borrower, the mortgage or real estate loan to such borrower will be deemed to be secured only to the extent of the value of the underlying collateral at the time of bankruptcy (as determined by the bankruptcy court), and the lien securing the mortgage or real estate loan will be subject to the avoidance powers of the bankruptcy trustee or debtor-in-possession to the extent the lien is unenforceable under state law. Additionally, in the event of a default under any senior debt, the junior or subordinate lender generally forecloses on the equity, purchases the senior debt or negotiates a forbearance or restructuring arrangement with the senior lender in order to preserve its collateral.

Security transactions and related investment income. Investment security transactions are accounted for on a trade date plus one basis for NAV calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is accrued as earned. Interest income includes coupon interest and amortization/accretion of premiums/discounts on debt securities. Debt obligations may be placed in a non-accrual status and related interest income may be reduced by stopping current accruals and writing off interest receivable when the collection of all or a portion of interest has become doubtful. Certain mortgage related fees, such as amendment fees and commitment fees, are recorded as Other income when earned. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds from litigation.

Overdrafts. Pursuant to the custodian agreement, the fund's custodian may, in its discretion, advance funds to the fund to make properly authorized payments. When such payments result in an overdraft, the fund is obligated to repay the custodian for any overdraft, including any costs or expenses associated with the overdraft. The custodian may have a lien, security interest or security entitlement in any fund property that is not otherwise segregated or pledged, to the maximum extent permitted by law, to the extent of any overdraft.

Expenses. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Statement of cash flows. A Statement of cash flows is presented when a certain percentage of the fund's investments is classified as Level 3 in the fair value hierarchy. Information on financial transactions that have been settled through the receipt and disbursement of cash is presented in the Statement of cash flows. The cash amount shown in the Statement of cash flows is the amount included in the fund's Statement of assets and liabilities and represents the cash on hand at the fund's custodian and does not include any short-term investments.

Federal income taxes. The fund intends to continue to qualify as a regulated investment company by complying with the applicable provisions of the Internal Revenue Code and will not be subject to federal income tax on taxable income that is distributed to shareholders. Therefore, no federal income tax provision is required.

For federal income tax purposes, as of December 31, 2023, the fund has a short-term capital loss carryforward of $19,726,284 and a long-term capital loss carryforward of $586,610 available to offset future net realized capital gains. These carryforwards do not expire.

19

John Hancock GA Mortgage Trust

Notes to financial statements 12-31-23

As of December 31, 2023, the fund had no uncertain tax positions that would require financial statement recognition, derecognition or disclosure. The fund's federal tax returns are subject to examination by the Internal Revenue Service for a period of three years.

Distribution of income and gains. Distributions to shareholders from net investment income and net realized gains, if any, are recorded on the ex-date. The fund generally declares and pays dividends quarterly. Capital gain distributions, if any, are typically distributed annually.

The tax character of distributions for the years ended December 31, 2023 and 2022 was as follows:

	December 31, 2023	December 31, 2022
Ordinary income	$70,936,820	$64,472,460

On November 15, 2022, the fund executed a $150,000,000 million tender offer that resulted in differing US GAAP vs tax treatment of proceeds distributed. For US GAAP purposes the transaction was treated as a redemption of shares whereas tax regulations dictate dividend distribution treatment to the extent of fund level earnings and profits. Given that the fund did not have sufficient earnings and profits to support the distribution, the entire value of the tender offer is treated as a return of capital for tax purposes.

As of December 31, 2023, there were no distributable earnings on a tax basis.

Such distributions and distributable earnings, on a tax basis, are determined in conformity with income tax regulations, which may differ from US GAAP. Distributions in excess of tax basis earnings and profits, if any, are reported in the fund's financial statements as a return of capital.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences, if any, will reverse in a subsequent period. The fund had no material book-tax differences at December 31, 2023.

3. Guarantees and indemnifications

Under the fund's organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the fund. Additionally, in the normal course of business, the fund enters into contracts with service providers that contain general indemnification clauses. The fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the fund that have not yet occurred. The risk of material loss from such claims is considered remote.

4. Fees and transactions with affiliates

The Advisor) serves as investment advisor for the fund. The fund does not have a principal underwriter. The fund has entered into a Placement Agency Agreement with John Hancock Investment Management Distributors LLC (the Distributor), an affiliate of the Advisor, to offer to sell shares of the fund. The Advisor is an indirect wholly-owned subsidiary of Manulife Financial Corporation (MFC), and the Distributor is an indirect, principally owned subsidiary of John Hancock Life Insurance Company (U.S.A.), which in turn is a subsidiary of MFC. Prior to April 20, 2023, the fund had a Placement Agency Agreement with John Hancock Distributors, LLC.

Management fee. The fund has an investment management agreement with the Advisor under which the fund pays an annual fee rate of 0.22% of average net assets, accrued daily and paid quarterly in arrears.

20

Notes to financial statements 12-31-23

Accounting and legal services. Pursuant to a service agreement, the fund reimburses the Advisor for all expenses associated with providing the administrative, financial, legal, compliance, accounting and recordkeeping services to the fund, including the preparation of all tax returns, periodic reports to shareholders and regulatory reports, among other services. These accounting and legal services fees incurred for the year ended December 31, 2023 amounted to an annual rate of 0.04% of the fund's average net assets.

Trustee expenses. The fund compensates each Trustee who is not an employee of the Advisor or its affiliates.

Co-investment. Pursuant to an Exemptive Order issued by the SEC, the fund is permitted to negotiate certain investments with entities with which it would be restricted from doing so under the 1940 Act, such as the Advisor and its affiliates. The fund is permitted to co-invest with affiliates if certain conditions are met. For example, the Advisor makes an independent determination of the appropriateness of the investment for the fund. Also, a "required majority" (as defined in the 1940 Act) of the fund's independent trustees make certain conclusions in connection with a co-investment transaction as set forth in the order, including that (1) the terms of the transactions, including the consideration to be paid, are reasonable and fair to the fund and shareholders and do not involve overreaching by the fund or shareholders on the part of any person concerned and (2) the transaction is consistent with the interests of shareholders and is consistent with the fund's investment objective and strategies. During the year ended December 31, 2023, investments entered into by the fund pursuant to the exemptive order amounted to $196,600,000.

5. Fund share transactions

Affiliates of the fund owned 100% of shares of the fund on December 31, 2023.

In January 2019, the Board of Trustees approved a tender offer repurchase policy for the fund. The share repurchase program does not obligate the fund to purchase a specific amount of shares.

On October 11, 2022, the fund commenced a cash tender offer (Offer) to repurchase shares in an amount up to $150,000,000 of its outstanding common shares at a price equal to 100% of the fund's net asset value per share as of November 15, 2022. The tender offer expired at 11:59 p.m., Eastern Time on November 8, 2022. Pursuant to the Offer, $150,000,000 was tendered and accepted by the fund at a net asset value of $17.36556 per share as determined as of November 15, 2022. Total shares of 8,637,787 were tendered for repurchase.

6. Purchase and sale of securities

Purchases and sales of securities, other than short-term investments and U.S. Treasury obligations, amounted to $223,000,000 and $48,847,003, respectively, for the year ended December 31, 2023. Purchases and sales of U.S. Treasury obligations aggregated $223,164,316 and $218,755,660, respectively, for the year ended December 31, 2023.

Tax information

Unaudited

For federal income tax purposes, the following information is furnished with respect to the distributions of the fund, if any, paid during its taxable year ended December 31, 2023.

The fund reports the maximum amount allowable as Section 163(j) Interest Dividends.

Qualified Interest Income (QII)

NonResident Alien (NRA) shareholders are normally subject to a 30% (or lower tax treaty rate depending on the country) NRA withholding tax on income and short-term capital gain dividends paid by a mutual fund, unless such dividends are designated as qualified interest income or qualified short-term capital gains, and therefore exempt from NRA withholding tax. Under the American Jobs Creation Act of 2004, the following percentages of ordinary dividends paid during the fiscal year ended December 31, 2023 are considered to be derived from "qualified interest income," as defined in Section 871(k)(1)(E) of the Code.

Investment objective, principal investment strategies, and principal risks (unaudited)

Investment Objective

The fund's investment objective is to generate current income, and to a lesser extent, capital appreciation.

Principal Investment Strategies

Under normal circumstances, the fund will seek to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings for investment purposes) in commercial mortgage loans. Mortgage loans may include fee simple mortgages and leasehold mortgages. The fund will only invest in United States dollar-denominated loans secured by property within the United States or its territories that are sourced by the Real Estate Finance Group of John Hancock Life Insurance Company (U.S.A.) or the Advisor and that are serviced by the Advisor or its affiliates. Commercial mortgage loans are fixed-income instruments, whereby loans are secured by income producing commercial real estate properties, with a mortgage on the real estate securing the collateral. The collateral for a fee simple mortgage consists of the borrower owned land and all improvements. The collateral for a leased fee mortgage (a type of fee simple mortgage) consists of the land only and the borrower's income from its ground lease to a tenant (the tenant owns the improvements). The collateral for a leasehold mortgage consists of the borrower's leasehold interest as the ground tenant in a ground lease. The fund may invest in loans either by transacting directly with the borrower or acquiring loans in secondary market transactions. The fund will typically invest in loans secured by stabilized assets, focusing on certain property types, which include retail, office, industrial and multi-family. The fund will selectively invest in loans secured by mixed use properties, hotels, parking facilities, and self-storage properties. The fund may also invest in subordinated debt obligations, including mezzanine debt, to the extent permitted by the fund's investment restrictions. The fund is non-diversified and its investments will be concentrated in the commercial mortgage industry.

Commercial mortgage loans are secured by multifamily or commercial property and are subject to risks of delinquency and foreclosure. The ability of a borrower to repay a loan secured by an income-producing property typically is dependent primarily upon the successful operation of such property rather than upon the existence of independent income or assets of the borrower.

The Advisor undertakes a comprehensive due diligence process, which includes a credit review and internal loan rating process as well as review of loan terms and collateral. The fund may invest in loans of any credit quality, although under normal circumstances the majority of the fund's investments will be investment-grade as determined by the Advisor. The fund's investment policies are based on credit ratings or equivalent assessments at the time of purchase. The fund may invest in loans of any maturity and duration.

Principal Risks

An investment in the fund is subject to investment and market risks, including the possible loss of the entire principal invested.

The fund's main risks are listed below in alphabetical order, not in order of importance.

Changing distribution level & return of capital risk. There is no guarantee prior distribution levels will be maintained, and distributions may include a substantial tax return of capital. A return of capital is the return of all or a portion of a shareholder's investment in the fund.

Commercial mortgage loans risk. Commercial real estate loans are generally not fully amortizing, which means that they may have a significant principal balance or balloon payment due on maturity. In certain situations, and during periods of credit distress, the unavailability of real estate financing may lead to default by a commercial borrower. In addition, in the absence of any such takeout financing, the ability of a borrower to repay a loan secured by an income-producing property will depend upon the successful operation of such property rather than upon the existence of independent income or assets of the borrower. If the net operating income of the property is reduced, the borrower's ability to repay the loan may be impaired. In the

event of any default under a mortgage or real estate loan held directly by the fund, it will bear a risk of loss of principal to the extent of any deficiency between the value of the collateral and the principal and accrued interest of the mortgage or real estate loan, which could have a material adverse effect on the profitability of the fund.

Concentration risk. Because the fund focuses on a single industry or sector of the economy, its performance depends in large part on the performance of that industry or sector. As a result, the value of an investment may fluctuate more widely since it is more susceptible to market, economic, political, regulatory, and other conditions and risks affecting that industry or sector than a fund that invests more broadly across industries and sectors.

Credit and counterparty risk. The issuer or guarantor of a fixed-income security may not make timely payments or otherwise honor its obligations. A downgrade or default affecting any of the fund's securities could affect the fund's performance.

Economic and market events risk. Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility, which could negatively impact performance. Reduced liquidity in credit and fixed-income markets could adversely affect issuers worldwide. Financial Institutions could suffer losses as interest rates rise or economic conditions deteriorate.

Fixed-income securities risk. A rise in interest rates typically causes bond prices to fall. The longer the average maturity or duration of the bonds held by a fund, the more sensitive it will likely be to interest-rate fluctuations. An issuer may not make all interest payment or repay all or any of the principal borrowed.

Changes in a security's credit quality may adversely affect fund performance. Additionally, the value of inflation-indexed securities is subject to the effects of changes in market interest rates caused by factors other than inflation (real interest rates). Generally, when real interest rates rise, the value of inflation-indexed securities will fall and the fund's value may decline as a result of this exposure to these securities.

Illiquid and restricted securities risk. Illiquid and restricted securities may be difficult to value and may involve greater risks than liquid securities. Illiquidity may have an adverse impact on a particular security's market price and the fund's ability to sell the security.

Liquidity risk. The extent (if at all) to which a security may be sold or a derivative position closed without negatively impacting its market value may be impaired by reduced market activity or participation, legal restrictions, or other economic and market impediments. Liquidity risk may be magnified in rising interest rate environments due to higher than normal redemption rates. Widespread selling of fixed-income securities to satisfy redemptions during periods of reduced demand may adversely impact the price or salability of such securities.

Lower-rated and high-yield fixed-income securities risk. Lower-rated and high-yield fixed-income securities (junk bonds) are subject to greater credit quality risk, risk of default, and price volatility than higher-rated fixed-income securities, may be considered speculative, and can be difficult to resell.

Mezzanine loans risk. Real estate mezzanine loans made to a mezzanine borrower are secured by the mezzanine borrower's equity interest in its mortgage borrower. As a mezzanine lender, the Advisor's advisory clients will have no lien on the real property as collateral for the mezzanine loan. Instead the value of the mezzanine collateral is the value of the real property above the amount of the mortgage loan(s). As a result, upon foreclosure of the mezzanine loan, the mezzanine lender typically becomes the owner of the mortgage borrower and, consequently, the indirect owner of the mortgaged property. The ability (or inability) of the mortgage borrower (or the mezzanine lender, if the mezzanine loan is foreclosed) to continue to service the mortgage liens is a key risk.

25

John Hancock GA Mortgage Trust

Investment objective, principal investment strategies, and principal risks (unaudited)

Non-diversified risk. Adverse events affecting a particular issuer or group of issuers may magnify losses for non-diversified funds, which may invest a large portion of assets in any one issuer or a small number of issuers.

Operational and cybersecurity risk. Cybersecurity breaches may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause a fund or its service providers to suffer data corruption or lose operational functionality. Similar incidents affecting issuers of a fund's securities may negatively impact performance. Operational risk may arise from human error, error by third parties, communication errors, or technology failures, among other causes.

Risks of Investing in Commercial Mortgage Loans secured by Ground Leases. The real property and repayment issues for a leasehold mortgage loan secured by the commercial borrower's interest as the ground tenant in a ground lease are similar to the risks associated with a fee simple commercial mortgage loan. The leasehold mortgage's main distinction is the type of property interest. The commercial borrower does not own the land and it may or may not own any improvements. Instead, the commercial borrower has a long term right to use the land. A leasehold loan is usually non-recourse in nature. Therefore, if a commercial borrower defaults on the leasehold loan, then the options for financial recovery are limited in nature, again similar to a fee simple mortgage. The options typically being either a negotiated settlement or amendment to the terms of the leasehold loan, or foreclosure. In the event of default, the lender will have no right to assets beyond the collateral attached to the leasehold loan. The leasehold loan documents include a provision that a default under the ground lease is a default under the leasehold loan. Therefore, in the event the lender exercises remedies and forecloses, the ground lease remains in place and the lender succeeds to the interests of the commercial borrower and becomes the ground tenant. Lender only gets rights granted to the borrower under the terms of the ground lease. The existence of lender's collateral is contingent upon the existence of the ground lease. Lender has additional remedies under a leasehold loan that allow for negotiated solutions with the ground landlord that may include, right to notice of any default, right to cure any default, and right enter into a new lease on substantially the same terms as the original ground lease.

Subordinated liens on collateral risk. Certain debt investments that the fund may make will be secured on a second priority basis by the same collateral securing senior secured debt of such companies. The first priority liens on the collateral will secure the fund's obligations under any outstanding senior debt and may secure certain other future debt that may be permitted to be incurred by the fund under the agreements governing the debt. The holders of obligations secured by the first priority liens on the collateral will generally control the liquidation of and be entitled to receive proceeds from any realization of the collateral to repay their obligations in full before the fund is so entitled. There can be no assurance that the proceeds, if any, from the sale or sales of all of the collateral would be sufficient to satisfy the debt obligations secured by the second priority liens after payment in full of all obligations secured by the first priority liens on the collateral.

Board considerations (unaudited)

EVALUATION OF ADVISORY AGREEMENT BY THE BOARD OF TRUSTEES

This section describes the evaluation by the Board of Trustees (the Board) of John Hancock GA Mortgage Trust (the fund) of the Advisory Agreement, between the fund and Manulife Investment Management Private Markets (US) LLC (the Advisor) (the Advisory Agreement). The Advisory Agreement was re-approved for an annual period at an in-person meeting on October 11, 2023. The Trustees who are not "interested persons" of the Trust as defined by the Investment Company Act of 1940, as amended (the 1940 Act) (the Independent Trustees) also met separately with counsel to the Independent Trustees to evaluate and discuss the information presented.

Continuation of Advisory Agreement

At an in-person meeting held on October 11, 2023, the Board, including all of the Independent Trustees, re-approved for an annual period the continuation of the Advisory Agreement. In considering the Advisory Agreement, the Board received in advance of the meeting a variety of materials relating to the fund and the Advisor, including, to the extent available, comparative performance (including performance information for an applicable benchmark index and aggregate performance information for commercial real estate whole loan providers), fee and expense information for other comparable investment companies, information regarding the Advisor's revenues and costs of providing services to the fund and any compensation paid to affiliates of the Advisor, and other information provided by the Advisor regarding the nature, extent, and quality of services provided by the Advisor under the Advisory Agreement. The information received and considered by the Board in connection with the October meeting was both written and oral. The Board also considered the nature, quality, and extent of the non-advisory services, if any, provided to the fund by the Advisor's affiliates. Throughout the process, the Board asked questions of and were afforded the opportunity to request additional information from management. The Board is assisted by counsel for the fund and the Independent Trustees are also separately assisted by independent legal counsel throughout the process. The Independent Trustees also received a memorandum from their independent legal counsel discussing the legal standards for their consideration of the proposed continuation of the Advisory Agreement and discussed the proposed continuation of the Advisory Agreement in private sessions with their independent legal counsel at which no representatives of management were present.

In approving the continuation of the Advisory Agreement, the Board, including the Independent Trustees, considered a variety of factors, including those discussed below. The Board also considered other market and economic factors and did not treat any single factor as determinative, and each Trustee may have attributed different weights to different factors. The Board noted that, at the meeting when the renewal of the Advisory Agreement is considered, particular focus is given to information concerning fund performance, comparability of fees and total expenses, and profitability. However, the Board noted that the evaluation process with respect to the Advisor is an ongoing one. In this regard, the Board also took into account discussions with management and information provided to the Board at prior meetings with respect to the services provided by the Advisor to the fund, including quarterly performance reports prepared by management containing reviews of investment results and prior presentations with respect to the fund.

Nature, extent, and quality of services. Among the information received by the Board from the Advisor relating to the nature, extent and quality of services provided to the fund, the Board reviewed information provided by the Advisor relating to its operations and personnel, descriptions of its organizational and management structure, and information regarding the Advisor's compliance and regulatory history, including its Form ADV. The Board also noted that on a regular basis it receives and reviews information from the Trust's Chief Compliance Officer (CCO) regarding the fund's compliance policies and procedures established pursuant to Rule 38a-1 under the 1940 Act. The Board observed that the scope of services provided by the Advisor, and of the undertakings required of the Advisor in connection with those services, including maintaining and monitoring its own and the fund's compliance programs, risk management and other programs, and cybersecurity programs, had expanded over time as a result of regulatory, market and

27

John Hancock GA Mortgage Trust

Board considerations (unaudited)

other developments. The Board considered that the Advisor is responsible for the management of the day-to-day operations of the fund, and for monitoring and reviewing the activities of third-party service providers. The Board also considered the significant risks assumed by the Advisor in connection with the services provided to the fund including investment, operational, enterprise, regulatory and compliance risks.

In considering the nature, extent, and quality of the services provided by the Advisor, the Trustees also took into account their knowledge of the Advisor's management and the quality of the performance of the Advisor's duties, through Board meetings, discussions and reports during the preceding year and through each Trustee's experience as a Trustee of the Trust and of the other trusts in the John Hancock group of funds complex (the John Hancock Fund Complex).

In the course of their deliberations regarding the Advisory Agreement, the Board considered, among other things:

(a)the skills and competency with which the Advisor has in the past managed the Trust's affairs;

(b)the background, qualifications, and skills of the Advisor's personnel;

(c)the Advisor's compliance policies and procedures and its responsiveness to regulatory changes and fund industry developments;

(d)the Advisor's administrative capabilities, including its ability to supervise the other service providers for the fund;

(e)the financial condition of the Advisor and whether it has the financial wherewithal to continue to provide a high level and quality of services to the fund;

(f)the Advisor's initiatives intended to improve various aspects of the fund's operations; and

(g)the Advisor's reputation and experience in serving as an investment advisor to the Trust.

The Board concluded that the Advisor may reasonably be expected to continue to provide a high quality of services under the Advisory Agreement with respect to the fund.

Investment performance. In considering the fund's performance, the Board noted that it reviews at its regularly scheduled meetings information about the fund's performance results. In connection with the consideration of the Advisory Agreement, the Board:

(a)reviewed information prepared by management regarding the fund's performance;

(b)considered the comparative performance of an applicable benchmark index;

(c)considered the performance of comparable funds, as included in the report prepared by an independent third-party provider of fund data; and

(d)took into account the Advisor's analysis of the fund's performance and its plans and recommendations regarding the fund's advisory arrangement generally.

The Board noted that while it found the comparative data provided by the independent third-party generally useful it recognized its limitations, including in particular that the data may vary depending on the end date selected and the results of the performance comparisons may vary depending on the selection of the peer group and the strategies and fund structures of the peers selected. In this regard the Board considered that management had represented that the peer group is not an exact match for the fund as members of the peer group may vary in structure, hold varying types of instruments, and employ different approaches to investing in commercial mortgage loans. The Board noted that the fund outperformed the peer group median for the one-year period ended June 30, 2023, but underperformed its peer group median for the quarter-to-date, year-to-date, two-year and three-year periods ended June 30, 2023. The Board also noted that the fund underperformed its benchmark index for the following periods: the quarter-to-date, year-to-date

Board considerations (unaudited)

and one-year periods ended June 30, 2023 and outperformed its benchmark index for the two-year and three-year periods ended June 30, 2023. The Board took into account management's discussion of the factors that contributed to the fund's recent underperformance relative to its peer group median for the quarter-to-date, year-to-date, two year and three-year periods, and relative to its benchmark index for the quarter-to-date, year-to-date and one-year periods.

The Board concluded that the fund's performance is being monitored and reasonably addressed, where appropriate.

Fees and Expenses.The Board reviewed comparative information regarding the fund's fees and expenses, including, among other data, the fund's management fees and net total expenses as compared to other comparable investment companies. The Board considered that the management fee and net total expenses were lower than the median advisory fee across the universe of funds presented and with respect to categories of funds that most closely align with the fund's investment strategy. The Board noted that the peer group was imperfect given the unique investment strategy and structure of the Fund. The Board took into account management's discussion of the fund's expenses. The Board reviewed information provided by the Advisor concerning investment advisory fees charged to other clients having similar investment mandates, if any. The Board considered any difference between the Advisor's services to the fund and the services they provide to other such comparable clients or funds.

The Board concluded that the advisory fees paid by the fund are reasonable in light of the nature, extent and quality of the services provided to the fund under the Advisory Agreement.

Profitability/Fall Out Benefits. In considering the costs of the services provided and the profits realized by the Advisor and its affiliates from the Advisor's relationship with the fund, the Board:

(a)reviewed financial information of the Advisor;

(b)considered that the Advisor will also provide administrative services to the fund on a cost basis pursuant to a services agreement;

(c)noted that affiliates of the Advisor will provide placement agency services to the fund;

(d)noted that the Advisor will derive reputational and other indirect benefits from providing advisory services to the fund;

(e)considered that the Advisor should be entitled to earn a reasonable level of profits in exchange for the level of services it will provide to the fund and the risks that it assumes as Advisor, including entrepreneurial, operational, reputational, and regulatory risk; and

(f)reviewed and considered information presented by the Advisor regarding the net profitability to the Advisor and its affiliates with respect to the fund.

Economies of Scale. In considering the extent to which the fund realizes any economies of scale and whether the fee level reflects these economies of scale for the benefit of the fund's shareholders, the Board took into account management's discussions of the current advisory fee structure, and, as noted above, the services the Advisor provides in performing its functions under the Advisory Agreement. In considering the extent to which economies of scale would be realized if the fund grows and whether the fee level reflects these economies of scale, the Board: (a) reviewed the fund's advisory fee structure and took into account management's discussion of the fund's advisory fee structure; and (b) also considered the potential effect of the fund's future growth in size on its performance and fees.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

John Hancock GA Mortgage Trust's (fund) Audit Committee must pre-approve all audit and non- audit services provided by the independent registered public accounting firm (the "Auditor") relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The fund's Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee's consideration of audit-related and non-audit services by the Auditor. The policies and procedures require that any audit-related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service provider that relates directly to the operations and financial reporting of a fund are subject to

approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $25,000 per instance/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $30,000 per instance/per fund are subject to specific pre-approval by the Audit Committee.

All audit services, as well as the audit-related and non-audit services that are expected to exceed the amounts stated above, must be approved in advance of provision of the service by formal resolution of the Audit Committee. At the regularly scheduled Audit Committee meetings, the Committee reviews a report summarizing the services, including fees, provided by the Auditor.

(e)(2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X:

Audit-Related Fees, Tax Fees, and All Other Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

(f)According to the registrant's principal accountant, for the fiscal year ended December 31, 2023, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

(g)The aggregate non-audit fees billed by the registrant's accountant(s) for services rendered to the registrant and rendered to the registrant's control affiliates for the fiscal year of the registrant were $3,079,277 for the fiscal year ended December 31, 2023, and $3,067,470 for the fiscal year ended December 31, 2022.

(h)The audit committee of the registrant has considered the non-audit services provided by the registrant's principal accountant(s) to the control affiliates and has determined that the services that were not pre-approved are compatible with maintaining the principal accountant(s)' independence.

(i)Not applicable.

Other Accounts the Portfolio Managers are Managing

The table below indicates, for each portfolio manager, information about the other accounts over which the portfolio manager has day-to-day investment responsibility. All information on the number of accounts and total assets in the table is as of December 31, 2023. For purposes of the table, "Other Pooled Investment Vehicles" may include investment partnerships and group trusts, and "Other Accounts" may include separate accounts for institutions or individuals, insurance company general or separate accounts, pension funds and other similar institutional accounts.

Number and value of accounts within the total accounts that are subject to a performance-based advisory fee: For each portfolio manager in the above table, 1 account with total assets (in millions) of $506.

Conflicts of Interest. The portfolio managers serve in a dual capacity as an officer of the Adviser and an employee and officer of one or more John Hancock affiliated companies (John Hancock).

In these roles they provide investment advice and/or investment management-related services to John Hancock as well the Adviser's advisory client accounts. As such there may be an incentive to favor one account over another, resulting in conflicts of interest. For instance, the Adviser or John Hancock may, for example, directly or indirectly, receive fees from an account that are higher than the fee (or other economic benefit) it receives from the Fund. In those instances, the portfolio manager may have an incentive to not favor the Fund over another account. The Adviser has adopted, as relevant, trade allocation and other policies and procedures that it believes are reasonably designed to address any potential conflicts of interest.

Compensation of Portfolio Managers. At the present time, the portfolio managers are paid by John Hancock a fixed annual salary as well as an employment compensation bonus that is currently based (in part) on the investment performance of certain accounts of John Hancock and its affiliates. This performance is independent of the Adviser's account-level performance on behalf of its clients. However, since commercial mortgage loans are invested as part of a co- investment program, the performance of the underlying investments of the John Hancock GA Mortgage Trust do indirectly contribute to overall compensation of the portfolio management team.

Share Ownership by Portfolio Managers. The following table indicates as of December 31, 2023, the value of shares beneficially owned by the portfolio managers in the Fund.

JOHN HANCOCK GA MORTGAGE TRUST

JOHN HANCOCK GA SENIOR LOAN TRUST

MANULIFE PRIVATE CREDIT FUND

SARBANES-OXLEY CODE OF ETHICS

FOR

PRINCIPAL EXECUTIVE & PRINCIPAL FINANCIAL OFFICER

1. Covered Officers/Purpose of the Code

This code of ethics (this "Code") for John Hancock GA Mortgage Trust, John Hancock GA Senior Loan Trust and Manulife Private Credit Fund, each an entity regulated under the Investment Company Act of 1940, as amended ("1940 Act"), which may issue shares in separate and distinct series (each investment company and series thereunder to be hereinafter referred to as a "Fund"), applies to each Fund's Principal Executive Officer ("President") and Principal Financial Officer ("Treasurer") (the "Covered Officers" as set forth in Exhibit A) for the purpose of promoting:

∙honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

∙full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the Securities and Exchange Commission ("SEC") and in other public communications made by the Fund;

∙compliance with applicable laws and governmental rules and regulations;

∙the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

∙accountability for adherence to the Code.

Each of the Covered Officers should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

2.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest Overview

A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund. Certain conflicts of interest arise out of the relationships between the Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "Investment Company Act") and the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund. Each of the Covered Officers is an officer or employee of the investment adviser or a service provider ("Service Provider") to the Fund. The Fund's, the investment adviser's and the Service Provider's compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the investment adviser and the Service Provider of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund, for the investment adviser or for the Service Provider), be involved in establishing policies and implementing decisions which will have different effects on the investment adviser, the Service Provider and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the investment adviser and the Service Provider and is consistent with the performance by the Covered Officers of their duties as officers of the Fund. Thus, if such participation is performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, it will be deemed to have been handled ethically. In addition, it is recognized by the Fund's Board of Trustees/Directors (the "Board") that the Covered Officers may also be officers or employees of one or more other investment companies covered by other Codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but the Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must:

∙not use his/her personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;

∙not cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than for the benefit of the Fund; and

∙not use material non-public knowledge of portfolio transactions made or contemplated for the Fund to trade personally or cause others to trade personally in contemplation of the market effect of such transactions.

Additionally, conflicts of interest may arise in other situations, the propriety of which may be discussed, if material, with the Fund's Chief Compliance Officer ("CCO"). Examples of these include:

∙serve as a director/trustee on the board of any public or private company;

∙the receipt of any non-nominal gifts;

∙the receipt of any entertainment from any company with which the Fund has current or prospective business dealings unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety (or other formulation as the Fund already uses in another code of conduct);

∙any ownership interest in, or any consulting or employment relationship with, any of the Fund's service providers, other than its investment adviser, any sub-adviser, principal underwriter, administrator or any affiliated person thereof; and

2

∙a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

3.Disclosure & Compliance

∙Each Covered Officer should familiarize himself or herself with the disclosure requirements generally applicable to the Fund;

∙Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's directors and auditors, and to governmental regulators and self-regulatory organizations;

∙Each Covered Officer should, to the extent appropriate within his/her area of responsibility, consult with other officers and employees of the Fund and the Fund's adviser or any sub-adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

∙It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

4.Reporting & Accountability

Each Covered Officer must:

∙upon adoption of the Code (or thereafter as applicable, upon becoming a Covered Officer), affirm in writing to the Fund's CCO that he/she has received, read, and understands the Code;

∙annually thereafter affirm to the Fund's CCO that he/she has complied with the requirements of the Code;

∙not retaliate against any employee or Covered Officer or their affiliated persons for reports of potential violations that are made in good faith;

∙notify the Fund's CCO promptly if he/she knows of any violation of this Code (Note: failure to do so is itself a violation of this Code); and

∙report at least annually any change in his/her affiliations from the prior year.

The Fund's CCO is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. However, any approvals or waivers sought by the Principal Executive Officer will be considered by the Fund's Board.

The Fund will follow these procedures in investigating and enforcing this Code:

∙the Fund's CCO will take all appropriate action to investigate any potential violations reported to him/her;

3

∙if, after such investigation, the CCO believes that no violation has occurred, the CCO is not required to take any further action;

∙any matter that the CCO believes is a violation will be reported to the Board;

∙if the Board concurs that a violation has occurred, the Board, upon its determination of a violation will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the Service Provider or the investment adviser or its board; or a recommendation to dismiss the Registrant's Executive Officer;

∙the Board will be responsible for granting waivers, as appropriate; and

ANNEX A

The Committee may take into account a wide variety of factors in considering Trustee candidates, including (but not limited to) the criteria set forth below. The Committee may determine that a candidate who does not satisfy these criteria in one or more respects should nevertheless be considered as a nominee if the Committee finds that the criteria satisfied by the candidate and the candidate's other qualifications demonstrate the appropriate level of fitness to serve.

General Criteria

1.Nominees should have a reputation for integrity, honesty and adherence to high ethical standards, and such other personal characteristics as a capacity for leadership and the ability to work well with others.

2.Nominees should have business, professional, academic, financial, accounting or other experience and qualifications which demonstrate that they will make a valuable contribution as Trustees.

3.Nominees should have a commitment to understand the Funds, and the responsibilities of a trustee/director of an investment company and to regularly attend and participate in meetings of the Board and its committees.

4.Nominees should have the ability to understand the sometimes conflicting interests of the various constituencies of the Funds, including shareholders and the investment adviser, and to act in the interests of all shareholders.

5.Nominees should not have, nor appear to have, a conflict of interest that would impair their ability to represent the interests of all the shareholders and to fulfill the responsibilities of a trustee.

6.Nominees should have experience on corporate or other institutional bodies having oversight responsibilities.

Application of Criteria to Current Trustees

The re-nomination of current Trustees should not be viewed as automatic, but should be based on continuing qualification under the criteria set forth above based on, among other things, the current Trustee's contribution to the Board and any committee on which he or she serves.

Review of Nominations

1.The Committee believes that it is in the best interests of each Trust and its shareholders to obtain highly-qualified candidates to serve as members of the Board.

2.In nominating candidates who would be Independent Trustees, the Committee believes that no particular qualities or skills nor any specific minimum qualifications or disqualifications are controlling or paramount. The Committee shall take into consideration any such factors as it deems appropriate; however, the appropriate mix of skills, expertise and attributes needed to maintain an effective board are sought in the applicant pool as part of every search the Board undertakes for new trustees, including but not limited to the diversity of thought, as well as of gender, race, ethnic background and geographic origin. These factors may also include (but are not limited to) the person's character, integrity, judgment, skill and experience with investment companies and other organizations of comparable purpose, complexity and size and subject to similar legal restrictions and oversight; the interplay of the candidate's experience with the experience of other Board members; and the extent to which the candidate would be a desirable addition to the Board and any Committees thereof. Other factors that the Committee may take into consideration include a person's availability and commitment to attend meetings and perform his or her responsibilities; whether or not the person has or had any relationships that might impair or appear to impair his or her independence, such as any business, financial or family relationships with Fund management, the investment adviser and/or any subadviser of the Funds, as applicable, Fund service providers, or their affiliates or with Fund shareholders. The Committee will strive to achieve a group that reflects a diversity of experiences in respect of industries, professions and other experiences, and that is diversified as to thought, gender, race, ethnic background and geographic origin.

3.While the Committee is solely responsible for the selection and recommendation to the Board of Independent Trustee candidates, the Committee may consider nominees recommended by any source, including shareholders, management, legal counsel and Board members, as it deems appropriate. The Committee may retain a professional search firm or a consultant to assist the Committee in a search for a qualified candidate. Any recommendations from shareholders shall be directed to the Secretary of the relevant Trust at such address as is set forth in the Trust's disclosure documents. Recommendations from management may be submitted to the Committee Chair. All recommendations shall include all information relating to such person that is required to be disclosed in solicitations of proxies for the election of Board members and as specified in the relevant Trust's By-Laws, and must be accompanied by a written consent of the proposed candidate to stand for election if nominated for the Board and to serve if elected

by shareholders.

4.Any shareholder nomination must be submitted in compliance with all of the pertinent provisions of Rule 14a-8 under the Securities Exchange Act of 1934 in order to be considered by the Committee. In evaluating a nominee recommended by a shareholder, the Committee, in addition to the criteria discussed above, may consider the objectives of the shareholder in submitting that nomination and whether such objectives are consistent with the interests of all shareholders. If the Board determines to include a shareholder's candidate among the slate of its designated nominees, the candidate's name will be placed on the Trust's proxy card. If the Board determines not to include such candidate among its designated nominees, and the shareholder has satisfied the requirements of Rule 14a-8, the shareholder's candidate will be treated as a nominee of the shareholder who originally nominated the candidate. In that case, the candidate will not be named on the proxy card distributed with the Trust's proxy statement.

5.As long as a current Independent Trustee continues, in the opinion of the Committee, to satisfy the criteria listed above, the Committee generally would favor the re-nomination of a current Trustee rather than a new candidate. Consequently, while the Committee will consider nominees recommended by shareholders to serve as trustees, the Committee may only act upon such recommendations if there is a vacancy on the Board, or the Committee determines that the selection of a new or additional Trustee is in the best interests of the relevant Trust. In the event that a vacancy arises or a change in Board membership is determined to be advisable, the Committee will, in addition to any shareholder recommendations, consider candidates identified by other means as discussed in this Annex A.

6.With respect to candidates for Independent Trustee, a biography of each candidate shall be acquired and shall be reviewed by counsel to the Independent Trustees and counsel to the Trusts to determine the candidate's eligibility to serve as an Independent Trustee.

7.The Committee may from time to time establish specific requirements and/or additional factors to be considered for Independent Trustee candidates as it deems necessary or appropriate.

8.After its consideration of relevant factors, the Committee shall present its recommendation(s) to the full Board for its consideration.

General Account Investments of John Hancock Life Insurance Company (U.S.A.)

Private Credit and Equity Group of Manulife Investment Management Private Markets

Canada Corp. and

Manulife Investment Management Private Markets (US) LLC

Proxy Voting Policy

General Account Investments of John Hancock Life Insurance Company U.S.A. ("JHUSA") is, among other things, an investment manager. In this capacity, JHUSA manages primarily institutional fixed income securities portfolios for JHUSA, its affiliates, certain of its and their insurance company separate accounts, and potentially certain other entities. Manulife Investment Management Private Markets (US) LLC ("Manulife IM PM (US)") and the Private Credit and Equity Group of Manulife Investment Management Private Markets Canada Corp. ("MIMPMCC") manages the assets of clients ( "Clients") for purposes of the Investment Advisers Act of 1940 (the "Advisers Act"). As fixed income managers, JHUSA, Manulife IM PM (US) and MIMPMCC seldom are called upon to vote equity securities on behalf of any of their managed accounts. When JHUSA and Manulife IM PM (US) do vote equity securities, it is often in the context of extra-judicial workouts and reorganizations of subject companies, or with respect to a mezzanine investment in which the vote may affect the value of related fixed income investments. Most proxy voting activity relate to routine annual corporate proxies related to equity positions.

This policy applies in those instances in which JHUSA or Manulife IM PM (US) is granted the discretion to vote proxies for a managed account and an equity security needs to be voted. If MIMPMCC is presented with a proxy vote for a security, the team will make a recommendation to Manulife IM PM (US). It is the responsibility of the relevant analyst to record the vote and follow the procedure outlined below.

I.General Principles

In order to set a framework within which proxy questions should be considered and voted, the following general principles should be applied:

1.The discretion to vote proxies for a Client's account or for any account governed by the Employee Retirement Income Security Act of 1974 ("ERISA") should be exercised keeping in mind JHUSA's and/or Manulife IM PM (US)'s fiduciary duty to use its best efforts to preserve or enhance the value of such account. We should vote on proxy questions with the goal of fostering the interests of the account owner or Client (or the participants and beneficiaries in the case of an ERISA account).

2.Proxy questions should be considered within the individual circumstances of the subject company. It is possible that individual circumstances might mean that a given proxy question could be voted differently than what is generally done in other cases.

3.If a proxy question clearly has the capability of affecting the economic value of the subject company's equity securities, the question should be voted in a way that attempts to preserve, or give the opportunity for enhancement of, the economic value of those securities.

4.In certain circumstances, even though a proposal might appear to be beneficial or detrimental in the short term, our analysis will conclude that over the long term greater value may be realized by voting in a different manner.

5.It is our policy that when we are given authority to vote proxies for any account, we must have full discretion and authority to vote all proxies for that account. We do not accept partial voting authority nor do we accept instructions from others on how to vote on specific issues.

1

Clients may wish to retain proxy voting authority and vote their own proxies if necessary to satisfy particular social, environmental or other goals.

Since in general the proxy voting will arise in connection with the individual circumstances of subject companies (workouts, mezzanine investments, etc.), JHUSA and Manulife IM PM (US) typically will not know in advance how they will vote. For routine matters JHUSA and Manulife IM PM (US) would expect to vote in accordance with the position of the subject company's management. For all other matters, JHUSA and Manulife IM PM (US) would decide how to vote on a case-by-case basis considering the relevant circumstances of the subject company.

Clients may obtain a record of how we voted the proxies for their accounts by contacting Investment Compliance by sending an email to bcfcomplianceoffice@jhancock.com.

II.Process

The analysts of JHUSA, who also provide services to Manulife IMPM (US) under a services agreement ("Analysts"), are responsible for performing research on the companies in which our managed accounts invest. The same Analysts are responsible for making recommendations or decisions regarding proxy voting, as they are the most familiar with company-specific issues. Portfolio managers also may provide input when appropriate. Proxy voting mechanics are the responsibility of the Analysts. Any proxy voted in accordance with this policy may be executed or directed to be executed by a Director or above.

It is our policy to vote all proxies received on behalf of Manulife IMPM (US)'s Client accounts, JHUSA's separate account clients and accounts governed by ERISA, except in unusual circumstances. We may abstain from voting a proxy if we conclude that the effect on the account holder's economic interests or the value of the portfolio holding is indeterminable or insignificant. We also may abstain from voting a proxy for cost reasons (e.g., costs associated with voting proxies of non-U.S. securities). In accordance with any applicable fiduciary duties, we would weigh the costs and benefits of voting proxy proposals relating to foreign securities and make an informed decision with respect to whether voting a given proxy proposal is prudent. Our decision would consider the expected effect that such vote, either by itself or together with other votes, would have on the value of the account holder's investment and whether this expected effect would outweigh the cost of voting.

We will maintain the records required to be maintained by us with respect to proxies in accordance with the requirements of the Advisers Act and, with respect to any registered investment company Clients, the Investment Company Act of 1940. These records include (a) a copy of each proxy statement received for a security held in a Client account, (b) a record of each vote cast on behalf of a Client account, (c) a copy of any document we created that was material to making a decision on how to vote proxies on behalf of a Client account or that memorializes the basis for that decision and (d) a copy of each written Client request for information on how the adviser voted proxies and a copy of any written response to any written or oral Client request for information on how the adviser voted proxies on behalf of the requesting Client. We may, but need not, maintain proxy statements that we receive regarding Client securities to the extent that such proxy statements are available on the SEC's on-line system. We may also rely upon a third party to maintain certain records required to be maintained under the Advisers Act or the Investment Company Act of 1940.

III.Conflicts of Interest

We have business relationships with various public and private institutions and may invest in the securities of certain of these institutions on behalf of our managed accounts. As noted above, we invest principally in fixed income securities with respect to which proxies are not required to be voted. In cases in which we are granted the discretion to vote proxies by an account holder, and an equity security is held in the corresponding account with respect to which a vote is required, we are responsible for voting proxies for that security. We recognize that the potential for conflicts of interest could arise in situations where we have material business relationships1 or

1In determining whether we have a material business relationship with a subject company we will consider, among other things, whether the subject company is a party to any material agreement listed on MFC's most recent Annual Information Form, attached to its 40-F filing.

2

material personal/family relationships2 with the subject company (or with a potential acquiring or target company in the case of a takeover proxy vote). To address these potential conflicts we have established a Conflicts of Interest and Investment Allocation Oversight Committee (the "Committee"), to provide oversight, in part, of proxy voting. When voting an equity proxy the Analyst will use reasonable efforts to determine whether a potential conflict may exist, including screening proxies against lists of companies with whom we may have a material business relationship (see Proxy Voting Policy Checklist). However, a potential conflict shall be deemed to exist only if the Analyst responsible for voting the proxy, actually knows of the potential conflict. If identified, the Analyst will consult with Private Markets and General Account Compliance to determine the materiality of the potential conflict. It is the responsibility of the Analyst to escalate any identified material potential conflicts of interest to the Committee for its review.

If a potential material conflict is escalated to the Committee then the Committee will meet to decide how to vote the proxy of any equity security in which we have identified a potential conflict. The Committee will consider the Analyst's recommendation, make a decision on how to vote the proxy and document the Committee's rationale for its decision.

Manulife IM PM (US) and JHUSA are wholly owned, indirect subsidiaries of Manulife Financial Corporation ("MFC"), a public company. It is our general policy not to acquire or hold MFC stock on behalf of our managed accounts. However, in the event that one of our managed accounts were to hold MFC stock, and we were responsible for voting an MFC proxy on behalf of that account, the Committee would decide on how to vote the MFC proxy in a manner that it believes will maximize value for the account holder. The Committee will document the rationale for its decision.

It is JHUSA's and Manulife IM PM (US)' policy for their personnel directly involved in the proxy voting process not to accept input on proxy voting from any person not so involved. Any such input given in contravention of this policy must be reported to the Compliance Office and documented. The Committee would then decide how to vote the proxy in question and would document the rationale for its decision.

If there is controversy or uncertainty about how any particular proxy question should be voted, or if anyone directly involved in the proxy voting process believes that he or she has been pressured to vote in a certain way, he or she will consult the Committee, the Private Markets and General Account Compliance Officer, or the Manulife IM PM (US) Chief Compliance Officer, as appropriate; and a decision will be made whether to refer the proxy to the Committee for voting. Final decisions on proxy voting will ultimately be made with the goal of enhancing the value of our managed accounts' investments.

2For this purpose, a material personal/family relationship is one that would be reasonably likely to influence how we vote proxies. To identify any such relationships, the Proxy Voting Checklist requires the disclosure of information about (i) personal and/or family relationships between JHUSA/Manulife IM PM (US) personnel involved in the proxy vote (e.g., the Analyst, portfolio manager and members of the Committee, as applicable) and directors or senior officers of the subject company and (ii) investments in the subject company by such JHUSA/Manulife IM PM (US) personnel or their family members.
