This means that: o You have a duty at all times to place the interests of our clients first. o All of your personal securities transactions must be conducted consistent with this Code of Ethics and in such a manner as to avoid any actual or potential conflict of interest or other abuse of your position of trust and responsibility. o You should not take inappropriate advantage of your position or engage in any fraudulent or manipulative practice with respect to our clients' accounts. See Exhibit A. 1. To Whom Does This Code Apply? This Code of Ethics applies to you if you are: o A director, officer or employee of John Hancock Life Insurance Company; or o A trustee or officer of the John Hancock Variable Series Trust I (the "VST"); or o A director, officer or employee of Signator Investors, Inc. ("Signator") who participates in making recommendations for, or receives information about, portfolio trades of the VST funds; or o Any other person deemed an Access Person by the Chief Investment Compliance Officer or the VST Compliance Officer. There are six main categories of persons covered by this Code of Ethics, taking into account their positions, duties and access to information regarding portfolio trades. You have been notified about which of these categories applies to you, based on the Office of Investment Compliance's understanding of your current role, and whether your designation is for VST purposes. If you have a level of investment access beyond your assigned category, or if you are promoted or change duties and as a result should more appropriately be included in a different category, it is your responsibility to notify your Code of Ethics contact person, who is identified in Appendix B, or Jude A. Curtis, Chief Investment Compliance Officer. Note: Dual Access Levels. Because this Code of Ethics covers John Hancock's investment advisory business as well as the VST, a very limited number of individuals who are involved in both activities will have an access level for John Hancock's investment advisory business and an access level for the VST which are different. These individuals must follow the reporting obligations and restrictions applicable to both levels (although there will be substantial overlap between levels). If you are a supervisor, and a person joins the Company who will be under your supervision or a person who was under your supervision leaves the Company, you are responsible for making sure that your Code of Ethics contact person is notified. 2 The basic definitions of the main categories of persons, with examples, are provided below. The more detailed definitions of each category are attached as Appendix C. - ------------------------- ---------------------- ----------------------- ---------------------- ---------------------- Level 1 Level 2 Level 3 Level 4 Non-Access Person Access Person Access Person Access Person Access Person - ------------------------- ---------------------- ----------------------- ---------------------- ---------------------- A person who regularly A person who A person who does not A senior officer who A person who is not participates in the regularly has access regularly have, but does not regularly a Level 1, 2, 3 or 4 investment process to trade data, but may have limited, work on or receive Access Person does not participate access to trade data information about in the investment investment matters process - ------------------------- ---------------------- ----------------------- ---------------------- ---------------------- Examples: Examples: Examples: Examples: Examples: - --------- -------- -------- -------- -------- o Portfolio o Auditing o Information o Senior o Human managers o Compliance Technology Officers who Resources o Analysts o Investment Services are not in o Sales o Traders Accounting o Public Levels 1, 2 or Associates o Investment Relations 3 o Accounts Law Division o Real Estate Payable Law Division - ------------------------- ---------------------- ----------------------- ---------------------- ---------------------- 3 2.

As is discussed in Section 3, Policies Outside the Code of Ethics, there are other policies which apply to directors, officers and employees of John Hancock. These policies contain a number of other requirements, including blackout periods for transactions in John Hancock Financial Services, Inc. ("JHFS") stock and preclearing of transactions in JHFS stock by directors, executive officers and certain employees. Please refer to those policies for guidance on their requirements. 4 3. Policies Outside the Code of Ethics John Hancock has certain policies that are not part of the Code of Ethics, but are equally important. They include the following: >> Company Conflict & Business Practice Policy ------------------------------------- A conflict of interest occurs when your Applies to: Level 1 Access Persons private interests interfere or could Level 2 Access Persons potentially interfere Persons with your Level 3 Access Persons responsibilities at work. You must not place Level 4 Access Persons yourself or the company in a position of Non-Access Persons Non-Access actual or potential conflict. ------------------------------------- This Policy covers a number of important issues and applies to all John Hancock personnel. For example, you cannot serve as a director of any company without first obtaining the required written executive approval. Other important issues in this Policy include: o personal investments or business relationships o misuse of inside information o receiving or giving of gifts, entertainment or favors o misuse or misrepresentation of your corporate position o disclosure of confidential or proprietary information o antitrust activities o political campaign contributions and expenditures on public officials >> JHLICO Inside Information Policy and Procedures The antifraud provisions of the federal ------------------------------------- securities laws generally prohibit persons Applies to: Level 1 Access Persons with material non-public information from Level 2 Access Persons trading on or communicating the information Level 3 Access Persons to others.

The rules (and sanctions) in this area apply to all John Hancock personnel and extend to activities both related and unrelated to your job duties. As an investment adviser, John Hancock Life Insurance Company is required to have an Inside Information Policy and Procedures. This policy covers a number of important issues pertaining to its investment advisory activities, such as: o The misuse of material non-public information o The information barrier procedure o The "restricted list" and the "watch list" o Broker letters and duplicate confirmation statements (see section 5 of this Code of Ethics). 5 >> JHFS Inside Information Policy and Blackout Periods for JHFS Stock John Hancock Financial Services, Inc. ------------------------------------- ("JHFS"), the publicly traded parent of John Applies to: Level 1 Access Persons Hancock Life Insurance Company, has a Policy Level 2 Access Persons Regarding Insider Trading and Dissemination Level 3 Access Persons of Inside Information, which covers, among Level 4 Access Persons other topics, prohibitions on trading while Non-Access Persons in possession of inside information about ------------------------------------- JHFS or any other company, and misuse of inside information about JHFS or any other company. This policy applies to all John Hancock personnel. One of the important provisions in the JHFS Inside Information Policy concerns blackout periods for trading in JHFS common stock. Directors, senior officers and certain other employees designated by their sector as having potential access to inside information about John Hancock because of their job responsibilities may not trade JHFS common stock during specific "blackout" periods starting on the last business day of each fiscal quarter and ending at the end of the day after the day of a public announcement of quarterly or annual earnings. Trading may occur outside the blackout period unless prohibited under the JHFS insider trading policy due to possession of inside information or other restrictions. More information about the JHFS blackout periods and whether those restrictions apply to you may be obtained from Marcia Casey, Senior Counsel, at (617) 572-9183, or Donna Rothbart, at (617) 572-0175. >> JHFS Fair Disclosure Policy The JHFS Fair Disclosure Policy governs the ------------------------------------- communications of JHFS representatives with Applies to: Level 1 Access Persons investors, investor representatives, Level 2 Access Persons analysts and other investment professionals, Level 3 Access Persons and applies to all John Hancock personnel. Level 4 Access Persons The Fair Disclosure Policy is intended to Non-Access Persons ensure that John Hancock representatives ------------------------------------- comply with SEC Regulation FD (for "Fair Disclosure") which is designed to prevent selective disclosure by public companies to shareholders and the financial community. The Fair Disclosure Policy addresses a number of topics relating to those communications and provides guidance on and procedures governing those communications. More information about the JHFS Fair Disclosure Policy may be obtained from Marcia Casey, Senior Counsel, at (617) 572-9183, or James G. Marchetti, Vice President and Counsel, at (617) 572-9193. 6 >> JHFS Policy Regarding Communications with Analysts, Investors and the Media The JHFS Policy Regarding Communications ------------------------------------- with Analysts, Investors and the Media, Applies to: Level 1 Access Persons which is different than the JHFS Fair Level 2 Access Persons Disclosure Policy, identifies additional Level 3 Access Persons requirements and procedures governing Level 4 Access Persons communications with analysts, investors and Non-Access Persons the media. This policy applies to all John ------------------------------------- Hancock personnel. More information about the JHFS Policy Regarding Communication with Analysts, Investors and the Media may be obtained from Marcia Casey, Senior Counsel, at (617) 572-9183, or James G. Marchetti, Vice President and Counsel, at (617) 572-9193. 4. Policies in the Code of Ethics For purposes of the following policies, a personal account is any account in your name, or any account in which you have a direct or indirect beneficial interest. >> Restriction on Gifts You and your family cannot accept ------------------------------------- preferential treatment or favors from Applies to: Level 1 Access Persons securities brokers or dealers or other Level 2 Access Persons organizations with which John Hancock might Level 3 Access Persons transact business. For the protection of Level 4 Access Persons both you and John Hancock, the appearance of Non-Access Persons a possible conflict of interest exercise ------------------------------------- caution in any instance in which business travel and lodging are paid for by someone other than John Hancock. The purpose of this policy is to minimize the basis for any charge that you used your John Hancock position to obtain for yourself opportunities which otherwise would not be offered to you. Please see the Company Conflict and Business Practice Policy's "Compensation and Gifts" section for additional details regarding restrictions on gifts and exceptions for "nominal value" gifts. >> Preclearance of Securities Transactions If you are a Level 1 Access person or a ------------------------------------- Level 2 Access person, you must "preclear" Applies to: Level 1 Access Persons (i.e.: receive advance approval of) any Level 2 Access Persons personal securities transactions. The ------------------------------------- preclearance policy applies to trades for your personal accounts, those of a spouse, "significant other," minor children or family members sharing your household, as well as all accounts over which you have discretion or give advice or information. Due to this preclearance requirement, participation in investment clubs is prohibited. 7 The following securities are exempt from the preclear policy: (1) direct obligations of the U.S. Government, (2) shares of all open-end mutual funds, (3) bankers' acceptances, bank certificates of deposit, commercial paper and high quality short-term debt instruments, including repurchase agreements. Shares of closed end mutual funds, such as exchange traded index funds, REITs and "Spiders" ("SPY"), are not exempted from preclearance without an exemption granted under Section 10 of this Code of Ethics. Ordinarily, Level 1 and Level 2 Access Persons, who are not VST Access Persons, do not have to preclear transactions in securities issued by JHFS, including JHFS stock and stock options. However, VST Access Persons are required to preclear transactions in securities issued by JHFS, which includes the sale or purchase of JHFS stock or the receipt or exercise of JHFS stock options. Level 3 and Level 4 Access persons are not required to preclear trades. However, please keep in mind that Level 3 and Level 4 Access persons are required to report securities transactions after every trade by submitting duplicate confirmation statements, as described in section 5 of this Code of Ethics. The preclearance policy is designed to proactively identify possible "problem trades" that raise frontrunning or other conflict of interest concerns (example: when a Level 1 Access person trades a security on the same day as a John Hancock client). Please keep in mind that even if you receive a preclearance, or are exempt from preclearing a securities transaction, you are still prohibited from engaging in any fraud or manipulative practice (such as frontrunning) with respect to a John Hancock client or a VST fund. You preclear a trade by following the steps outlined in the preclearance procedures, which are attached as Appendix D. Please note that: o You may not trade until clearance is received. o Clearance approval is valid only for the request date and next business date for Level 1 preclearers and the date granted for Level 2 preclearers. o A separate procedure should be followed for requesting preclearance of a private placement or a derivative, as detailed in Appendix D. The Office of Investment Compliance must maintain a five-year record of all clearances of private placement purchases by some access persons, and the reasons supporting the clearances. NOTE: Other Obligations to Preclear JHFS Stock. Directors and executive officers must preclear their transactions in JHFS stock with Marcia Casey, Senior Counsel, (617) 572-9183, or James G. Marchetti, Vice President and Counsel, (617) 572-9193. In addition, certain employees designated as part of the Company's stock repurchase program must preclear purchases and sales of JHFS stock with Marcia Casey or James G. Marchetti. 8 >> Open Order Blackout If you are a Level 1 Access person, you are ------------------------------------- prohibited from buying or selling a security Applies to: Level 1 Access Persons on a day in which a portfolio or account ------------------------------------- managed by John Hancock has a pending buy or sell order for that security until that order is executed or withdrawn. You will be required to sell any security purchased in violation of this policy unless it is determined that no conflict of interest exists in relation to that security. Any profits realized on trades in violation of this policy must be surrendered by check payable to John Hancock Life Insurance Company and will be contributed by John Hancock to a charity designated by John Hancock. This policy applies to holdings in your personal accounts, those of a spouse, "significant other," minor children or family members sharing your household, as well as all accounts over which you have discretion or give advice or information. >> Ban on IPOs If you are a Level 1 Access person, you may ------------------------------------- not acquire securities in an initial public Applies to: Level 1 Access Persons offering. You may not purchase any newly- ------------------------------------- issued securities until the next business (trading) day after the offering date. This policy applies to trades for your personal accounts, those of a spouse, "significant other," minor children or family members sharing your household, as well as all accounts over which you have discretion or give advice or information. There are two main reasons for this prohibition: (1) these purchases may suggest that persons have taken inappropriate advantage of their positions for personal profit; and (2) these purchases may create at least the appearance that an investment opportunity that should have been available to the client was diverted to the personal benefit of an individual employee. You may request an exemption for certain investments that do not create a potential conflict of interest, such as: (1) securities of a mutual bank or mutual insurance company received as compensation in a demutualization and other similar non-voluntary stock acquisitions; or (2) fixed rights offerings. If you are registered with Signator Investors, Inc., you are prohibited from acquiring securities in an initial public offering, regardless of whether you are a Level 1, 2, 3 or 4 Access person or a Non-Access person. You should consult the Insurance and Securities Market Conduct Manual for additional guidance if you are registered with Signator Investors, Inc. 9 >> Disclosure of Private Placement Conflicts If you are a Level 1 Access person and you ------------------------------------- own securities purchased in a private Applies to: Level 1 Access Persons placement (such as a limited partnership), ------------------------------------- you must disclose that holding when you participate in a decision to purchase or sell that same issuer's securities for a John Hancock client's account. Private placements are securities exempt from SEC registration under section 4(2), section 4(6) or rules 504 -506 of the Securities Act of 1933. The investment decision must be subject to an independent review by investment personnel with no personal interest in the issuer. This policy applies to holdings in your personal accounts, those of a spouse, "significant other," minor children or family members sharing your household, as well as all accounts over which you have discretion or give advice or information. The purpose of this policy is to provide appropriate scrutiny in situations in which there is a potential conflict of interest. Level 1 Access persons (as well as Level 2 Access persons who are not subject to this disclosure obligation) must pre-clear any investment in a private placement by you, your spouse, "significant other," minor children or family members sharing your household, as well as for any accounts over which you have discretion or give advice or information. >> Seven Day Blackout Period If you are a portfolio manager (or were ------------------------------------- identified to the Office of Investment Applies to: Level 1 Access Persons Compliance as part of a portfolio management ------------------------------------- team), you are prohibited from buying or selling a security within seven calendar days before and after that security is traded for a portfolio or account that you manage unless no conflict of interest exists in relation to that security. In addition, all Level 1 Access persons are prohibited from knowingly buying or selling a security within seven calendar days before and after that security is traded for a portfolio or account managed by John Hancock unless no conflict of interest exists in relation to that security. If a portfolio or account managed by John Hancock trades in a security within seven calendar days before or after you trade in that security, you may be required to demonstrate that you did not know that the trade was being considered for that portfolio or account. You will be required to sell any security purchased in violation of this policy unless it is determined that no conflict of interest exists in relation to that security. Any profits realized on trades during a seven day blackout period must be surrendered by check payable to John Hancock Life Insurance Company and will be contributed by John Hancock to a charity designated by John Hancock. 10 This policy applies to holdings in your personal accounts, those of a spouse, "significant other" or family members sharing your household, as well as all accounts over which you have discretion or give advice or information. >> Ban on Short-Term Profits If you are a Level 1 Access person for the ------------------------------------- VST, you cannot profit from the purchase and Applies to: Level 1 Access Persons sale (or sale and purchase) of the same (or (VST Only) equivalent) securities within 60 calendar ------------------------------------- days. The purpose of this policy is to address the risk, real or perceived, of frontrunning or other abusive practices involving short-term personal trading. Any profits realized on short-term trades must be surrendered by check payable to John Hancock Life Insurance Company and will be contributed by John Hancock to a charity designated by John Hancock. This policy applies to trades for your personal accounts, those of a spouse, "significant other," minor children or family members sharing a household, as well as all accounts over which you have discretion or give advice or information. If you give away a security, it is considered a sale. You may invest in derivatives or sell short provided the transaction period exceeds the 60-day holding period. You may request an exemption from this policy for involuntary sales due to unforeseen corporate activity (such as a merger), or hardship reasons (such as unexpected medical expenses) by sending an e-mail to Jude A. Curtis, VST Compliance Officer. NOTE: Short Swing Profit Rules for JHFS Directors and Executive Officers. JHFS directors and executive officers are subject to different regulations and rules on short swing profits relating to trading in JHFS stock. Questions regarding the short swing profit rules should be directed to Marcia Casey, Senior Counsel, at (617) 572-9183, or James G. Marchetti, Vice President and Counsel, at (617) 572-9193. >> Actual Trade Blackout If you are a Level 1 Access person for the ------------------------------------- VST or a Level 2 Access person for the VST, Applies to: Level 1 Access Persons you are Applies to: prohibited from buying (VST Only) or selling a security in Level 1 Access Level 2 Access Persons which a VST fund has traded during the past (VST Only) five Persons business days. ------------------------------------- You will be required to sell any security purchased in violation of this policy unless it is determined that no conflict of interest exists in relation to that security.

Shares of closed end mutual funds, such as exchange traded index funds, REITs, and "Spiders" ("SPY"), are not exempted. Because this requirement only applies to VST Access Persons, holdings of securities issued by JHFS, including JHFS stock and stock options, must be reported on these holding reports. o all securities brokerage accounts (including brokerage accounts that only contain securities exempt from reporting, such as shares of open-end mutual funds). >> Quarterly Transaction Reports You must file a quarterly transaction report ------------------------------------- within 10 calendar days after the end of a Applies to: Level 1 Access Persons Applies to: calendar quarter if you are a Level 2 Access Persons Level 1, Level 2 Level 1 Access or Level 3 Level 3 Access Persons Access person.

Limited Access Persons There is an additional category of persons called "Limited Access" persons. This category consists only of directors of John Hancock Life Insurance Company and trustees of the VST who are not also officers of John Hancock Life Insurance Company. A more detailed definition of Limited Access persons, and a list of the policies that apply to them, is attached as Appendix E. 8. Sub-Advisers A sub-adviser to a VST fund has a number of responsibilities under this Code of Ethics, as described in Appendix F. 9. Reporting Violations If you know of any violation of our Code of Ethics, you have a responsibility to immediately report it. You should also report any deviations from the controls and procedures that safeguard John Hancock and the assets of our clients. You can report confidentially to: o Jude A. Curtis, Chief Investment Compliance Officer (572-6990); or o Your manager or department head. 10. Interpretation and Enforcement This Code of Ethics cannot anticipate every situation in which personal interests may be in conflict with the interests of our clients. You should be responsive to the spirit and intent of this Code of Ethics as well as its specific provisions. When any doubt exists regarding any Code of Ethics provision or whether a conflict of interest with clients might exist, you should discuss the transaction beforehand with the Chief Investment Compliance Officer, Jude A. Curtis, at (617) 572-6990. 14 The Code of Ethics is designed to detect and prevent fraud against clients and VST investors, and to avoid the appearance of impropriety. If you feel inequitably burdened by any policy, you should feel free to contact Chief Investment Compliance Officer, Jude A. Curtis for an exception to this policy. Exceptions may be granted by the Office of Investment Compliance where warranted by applicable facts and circumstances. The Office of Investment Compliance may grant a general exception to certain restrictions in this Code of Ethics for trades in large capitalization stocks. Preclearance of these transactions would, however, still be required. To provide assurance that policies are effective, Compliance will monitor and check personal securities transaction reports and certifications against client or fund portfolio transactions. Other internal auditing procedures may be adopted from time to time. Additional administration and recordkeeping procedures are described in Appendix G. The Office of Investment Compliance will refer violations to the Ethics Committee for review and appropriate action. The Ethics Committee includes the Chief Investment Officer, the Chief Investment Compliance Officer and another senior officer from the Investment Sector. The following factors will be considered when the Ethics Committee determines a fine or other disciplinary action: o the person's position and function (senior personnel may be held to a higher standard); o the amount of the trade; o whether the funds or accounts hold the security and were trading the same day; o whether the violation was by a family member. o whether the person has had a prior violation and which policy was involved. o whether the employee self-reported the violation. Violations by NASD registered persons are reported to the NASD Compliance Officer at John Hancock Life Insurance Company. Sanctions for violations could include fines, limitation of personal trading activity, suspension, termination of employment and/or a report to the appropriate regulatory authority. 15 Appendix A: Sample Regulatory Concerns and Examples By way of example only, the following constitute fraudulent or manipulative practices and are of great concern to law enforcement agencies: o Frontrunning Example: In your capacity as a portfolio manager, you decide to purchase a substantial position in a XYZ security for client accounts because you think it is undervalued. You also want to invest in the XYZ security for your personal account. You place your order before the client orders so that you will obtain the lowest price. o Trading on inside information Example: In the course of a Committee of Finance meeting, you learn that the management of ABC Corporation seeks financing from the Company to take ABC private in a leveraged buy-out. Upon leaving the meeting, you direct your broker to purchase ABC stock, although the proposed buy-out has not been publicly disclosed. o Tipping inside information Example: In your capacity as an analyst researching Acquirer Corp., you are provided with non-public information that Acquirer plans to make a hostile takeover offer for Target Corporation.
