IMPORTANT INFORMATION FOR SHAREHOLDERS IN PUTNAM HIGH QUALITY BOND FUND

The document you hold in your hands contains a combined prospectus/proxy
statement and proxy card. A proxy card is, in essence, a ballot. When you fill
out your proxy card, it tells us how to vote on your behalf on important issues
relating to your fund. If you complete and sign the proxy, we'll vote it exactly
as you tell us. If you simply sign the proxy, we'll vote it in accordance with
the Trustees' recommendation on page __.

We urge you to carefully review the prospectus/proxy statement, fill out your
proxy card, and return it to us. When shareholders don't return their proxies in
sufficient numbers, we have to make follow-up solicitations, which can cost your
fund money.

We want to know how you would like to vote and welcome your comments. Please
take a few minutes with these materials and return your proxy card to us.

A MESSAGE FROM THE CHAIRMAN

(photograph of George Putnam appears here)

Dear Shareholder:

I am writing you to ask you for your vote on an important matter that affects
your investment in Putnam High Quality Bond Fund (the "High Quality Bond Fund").
While you are, of course, welcome to join us at the High Quality Bond Fund's
meeting, most shareholders cast their vote by filling out and signing the
enclosed proxy card.

We are asking for your vote on the following matter:

1. Approval or disapproval of a proposed merger of the High Quality Bond Fund
into Putnam American Government Income Fund (the "American Government Fund"). In
this merger, your shares of the High Quality Bond Fund would, in effect, be
exchanged, on a tax-free basis, for shares of the American Government Fund with
an equal net asset value.

The Trustees of the High Quality Bond Fund recommend approval of the merger,
because they believe it offers shareholders of the fund the opportunity to
invest in a substantially larger fund with similar investment policies but that
has a greater potential to achieve economies of scale and a lower expense ratio.

The two funds are both fixed income funds investing primarily in U.S. government
and agency securities. The High Quality Bond Fund seeks high current income. To
the extent consistent with seeking high current income, capital preservation and
long-term total return are its secondary goals. The American Government Fund
seeks high current income, with preservation of capital as its secondary
objective.

Both Funds seek their goals by investing, under normal market conditions, at
least 65% of their assets in U.S. government securities, which are debt
securities issued or guaranteed by the U.S. government, by certain of its
agencies, or by various instrumentalities established or sponsored by the U.S.
government. The American Government Fund may also invest up to 35% of its total
assets in highly rated mortgage-backed securities that are privately issued. The
High Quality Bond Fund has additional flexibility. It can invest a substantial
portion of its total assets in investment grade obligations, including those of
foreign government and corporate issuers, as well as asset-backed securities.

Your vote is important to us. We appreciate the time and consideration I am sure
you will give this important matter. If you have questions about the proposal,
please call 1-800-225-1581, or call your financial advisor.

                                    Synopsis

The responses to the questions that follow provide an overview of key points
typically of concern to shareholders considering a proposed merger between
funds. These responses are qualified in their entirety by the remainder of the
Prospectus/Proxy Statement, which contains additional information and further
details regarding the proposed merger.

1. What is being proposed?

The Trustees of the Funds are recommending that shareholders approve the merger
of the High Quality Bond Fund into the American Government Fund. If approval by
shareholders all of the assets of the High Quality Bond Fund will be transferred
to the American Government Fund in exchange for shares of the American
Government Fund with a value equal to those assets net of liabilities and for
the assumption by the American Government Fund of all of the liabilities of the
High Quality Bond Fund. Immediately following the transfer the American
Government Fund shares received by the High Quality Bond Fund will be
distributed to its shareholders, pro rata.

2. What will happen to my shares of the High Quality Bond Fund as a result of
the merger?

Your shares of the High Quality Bond Fund will, in effect, be exchanged on a
tax-free basis for shares of the American Government Fund with an equal total
net asset value.

3. Why are the Trustees proposing the merger?

As discussed in more detail below, the two funds are similar in investment
strategy and policy. The Trustees believe that combining the two similar funds
will result in lower expenses for fund shareholders without changing in a
fundamental way the essential investment profile of the funds. In addition the
Trustees believe the combined fund will offer greater potential for increased
sales and thus the potential for further economies of scale. As the American
Government fund is considerably larger the Trustees believe it is appropriate
for the smaller High Quality Bond Fund to be merged into the larger fund.

4. How do the investment goals, policies and restrictions of the two funds
compare?

   
The investment goals and policies of the two funds are similar. Each is an
income oriented fund investing primarily in U.S. government and agency
securities. The High Quality Bond Fund seeks high current income. Capital
preservation and long-term total return are its secondary goals, but only to the
extent consistent with seeking high current income. The American Government Fund
seeks high current income, with preservation of capital as its secondary
objective.
    

Both Funds seek their goals by investing, under normal market conditions, at
least 65% of their


                                      -11-
<PAGE>

assets in U.S. government securities, which are debt securities issued or
guaranteed by the U.S. government, by certain of its agencies, or by various
instrumentalities established or sponsored by the U.S. government. The American
Government Fund may also invest up to 35% of its total assets in mortgage-backed
securities that are privately issued and at the time of purchase rated at least
AAA or Aaa by a nationally recognized securities rating. The High Quality Bond
Fund has broader flexibility than the American Government Fund. It can invest up
to 35% of its total assets in a wide variety of investment grade obligations,
including privately issued mortgage-backed and asset-backed securities as well
as securities of foreign government and corporate issuers. The High Quality Bond
Fund's investments in non-U.S. government securities must be rated at the time
of purchase at least Baa or BBB by a nationally recognized securities rating
agency.

5. How do the management fees and other expenses of the two funds compare, and
what are they estimated to be following the merger?

   
The American Government Fund and the High Quality Bond Fund have identical fee
and other expense structures. However, because the American Government Fund is
substantially larger than the High Quality Bond Fund, its expenses are lower on
a per share basis due to its attainment of break points in the management fee
schedule and other economies of scale. As of January 31, 1999, the American
Government Fund and the High Quality Bond Fund had net assets of $1,559,262,662
and $384,970,695, respectively. Each fund is subject to the same management fee
schedule. However, as shown in the Annual Fund Operating Expense table below, in
each fund's most recent fiscal year the American Government Fund paid a
management fee that is .09% lower on a per share basis than that of the High
Quality Bond Fund. On a pro forma basis, giving effect to the merger, the
combined fund's effective management fees will be .11% lower on a per share
basis than those of the High Quality Bond Fund. Also as shown in the table, the
American Government Fund's "other expenses" were .04% lower on a per share basis
than those of the High Quality Bond Fund in each fund's last fiscal year. The
pro forma post-merger total operating expenses of the American Government Fund
are also lower than those of the High Quality Bond Fund on a per share basis.
    

The sales charges and the maximum amounts payable under the distribution plans,
adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940, for the
Funds are identical. 12b-1 fees are 0.25%, 1.00% and 0.50% of average net assets
attributable to Class A, Class B and Class M shares, respectively.

                                      -12-

The following tables summarize the maximum fees and expenses you may pay when
investing in the Funds, expenses that each of the Funds incurred in the 12
months ending December 31, 1998 and estimated expenses that Putnam Management
expects the combined fund to incur in the first year following the merger.

</TABLE>

* Higher 12b-1 fees borne by class B and class M shares may cause long-term
class B and class M shareholders to pay more than the total sales charges paid
by class A shareholders.

** A deferred sales charge of up to 1.00% is assessed on certain redemptions of
Class A shares that were purchased without an initial sales charge as part of an
investment of $1 million or more.

*** 5.0% in the first year, declining to 1.0% in the sixth year, and eliminated

The tables are provided to help you understand the expenses of investing in the
Funds and your share of the operating expenses that each Fund incurs and that
Putnam Management expects the combined fund to incur in the first year following
the merger. The expenses shown in the table do not reflect the application of
credits related to expense offset arrangements that reduce certain fund
expenses.

Examples

These examples translate the "Total Annual Fund Operating Expenses" shown in the
preceding table into dollar amounts. By doing this, you can more easily compare
the cost of investing in the Funds. The examples make certain assumptions. They
assume that you invest $10,000 in a Fund for the time periods shown and then,
except as shown for Class B shares, redeem all your shares at the end of these
periods. They also assume 5% return on your investment each year


                                      -14-

and that a Fund's operating expenses remain the same. The examples are
hypothetical; your actual costs and returns may be higher or lower.

6. What are the federal income tax consequences of the proposed Merger?

For federal income tax purposes, no gain or loss will be recognized by the High
Quality Bond Fund or its shareholders as a result of the merger.

7. Will my dividend be affected by the merger?

After the merger you will continue to receive distributions of any net
investment income once a month and any net realized capital gains at least once
a year. Except as described below, your distributions will continue to be either
reinvested or paid in cash, according to the option you selected with the High
Quality Bond Fund. Of course, the amount of these distributions will reflect the
investment policies of the American Government Fund. Since the American
Government Fund does not invest in corporate or foreign bonds as High Quality
Bond Fund does, its dividend rate can be expected to be lower than that of the
High Quality Bond Fund under normal market conditions.

The American Government Fund will not permit any High Quality Bond Fund
Shareholder holding certificates for High Quality Bond Fund shares at the time
of the merger to receive cash dividends or other distributions, receive
certificates for shares issued in the merger ("Merger Shares"), exchange Merger
Shares for shares of other investment companies managed by Putnam Management, or
pledge or redeem Merger Shares until such certificates for High Quality Bond
Fund shares have been surrendered, or, in the case of lost certificates, until
an adequate surety bond has been posted.

If a shareholder is not for that reason permitted to receive cash dividends or
other distributions on Merger Shares, the American Government Fund will pay all
such dividends and distributions in additional shares, notwithstanding any
election the shareholder may have made previously to receive dividends and
distributions on High Quality Bond Fund shares in cash.

8. Do the procedures for purchasing, redeeming and exchanging shares of the two
funds differ?

No. The procedures for purchasing and redeeming shares of each Fund, and for
exchanging such shares of each Fund for shares of other Putnam funds, are
identical.

Both Funds currently offer three classes of shares. Shares of both Funds may be
purchased either through investment dealers that have sales agreements with
Putnam Mutual Funds Corp. ("Putnam Mutual Funds") or directly through Putnam
Mutual Funds at prices based on net asset value, plus varying sales charges,
depending on the class and number of shares purchased. Reinvestment of
distributions by the Funds are made at net asset value for all classes of
shares.

Shares of each Fund may be redeemed any day the New York Stock Exchange is open
at their net asset value next determined after receipt by the Fund of a properly
completed redemption

                                      -16-
<PAGE>

request either directly by a Fund or through an investment dealer.

Shares of both Funds may be exchanged after a ten-day holding period for shares
of the same class of certain other Putnam funds.

9. How will I be notified of the outcome of the merger?

If the proposed merger is approved by shareholders, you will receive
confirmation after the reorganization is completed, indicating your new account
number, the number of shares you are receiving and the procedures for
surrendering your certificates if you have any. If the merger is not approved,
shareholders will be notified, and the results of the meeting will be provided
in the next annual report of the High Quality Bond Fund.

10. Will the number of shares I own change?

Yes, but the total value of the shares of the American Government Fund you
receive will equal the total value of the shares of the High Quality Bond Fund
that you hold at the time of the merger. Even though the net asset value per
share of each fund is different, the total value of a shareholder's holdings
will not change as a result of the merger.

                                  Risk factors

What are the principal risk factors associated with an investment in the
American Government Fund, and how do they compare with those for the High
Quality Bond Fund?

Because the Funds share similar goals and policies, the risks of an investment
in the American Government Fund are similar to the risks of an investment in the
High Quality Bond Fund. A more detailed description of certain risks associated
with an investment in the American Government Fund is contained in the American
Government Fund Prospectus.

Lower Yielding Assets.  Although the two funds' investment policies are similar
they are not identical. The American Government Fund's investment policies are
more restrictive than those of the High Quality Bond Fund. Although both can
invest up to 35% of their assets in non-U.S. government and agency securities,
the American Government fund is limited to investing in AAA or Aaa rated
mortgage backed securities while the High Quality Bond fund may invest in a
broad range of investment grade U.S. corporate and foreign debt. Since both
corporate debt and foreign debt have additional risks, the Trustees and Putnam
Management believe that as a general matter, a fund with a substantial portion
of these securities involves more risk than one with a substantial portion of
its assets invested in U.S. government and agency securities. However,
investment grade corporate debt and foreign government debt will generally have
higher yields, and the diversification they add may reduce overall risk at times
when U.S. government securities markets are declining. Thus, although the
American Government Fund's overall portfolio risk may generally be lower and its
return less volatile, its yield and total return

                                      -17-
<PAGE>

can also be expected to be lower.

Interest rate risk.  The values of debt investments usually rise and fall in
response to changes in interest rates. Declining interest rates will generally
raise the value of existing debt investments, and rising interest rates will
generally lower the value of existing debt investments. Changes in the values of
debt investments usually will not affect the amount of income the fund receives
from them, but will affect the value of the fund's shares. Interest rate risk is
often greater for investments with longer maturities.

Premium investments.  Like the High Quality Bond Fund, the American Government
Fund may invest in so-called "premium" investments, which offer interest rates
higher than prevailing market rates. In addition, during times of declining
interest rates, many of the fund's investments may offer interest rates that are
higher than current market rates. When the fund holds these Apremium@
investments, shareholders are likely to receive higher dividends (but will bear
a greater risk that the value of the fund's shares will fall) than they would if
the fund held investments that offered current market rates of interest. Premium
investments involve a greater risk of loss, because their values tend to decline
over time.

Credit risk.  Although U.S. government investments are generally considered to
have the least credit risk -- the risk that the issuer will fail to make timely
payments of interest and principal -- they are not entirely free of credit risk.
In addition, the values of these investments will still fluctuate in response to
changes in interest rates. Other securities in which the fund may invest are
subject to varying degrees of risk of default. These risk factors include the
creditworthiness of the issuer and, in the case of mortgage-backed securities,
the ability of the underlying mortgagors or other borrowers to meet their
obligations.

Prepayment risk.  Traditional debt investments typically pay a fixed rate of
interest until maturity, when the entire principal amount is due. By contrast,
payments on mortgage-backed investments typically include both interest and a
partial payment of principal. Principal may also be prepaid voluntarily, or as a
result of refinancing or foreclosure. The fund may have to invest the proceeds
from prepayments under less attractive terms and yields.

Prepayments are particularly common during periods of declining interest rates,
when property owners seek to refinance their mortgages on more favorable terms;
the reverse is true during periods of rising interest rates. Mortgage-backed
investments are therefore less likely to increase in value during periods of
declining interest rates than other debt investments of comparable maturities.
In addition, they have a higher risk of decline during periods of rising
interest rates because declining prepayment rates effectively increase the
average maturity of the fund's investments (and, therefore, its sensitivity to
changes in interest rates) at times when that is least desirable. These
investments can increase the volatility of the fund.

Frequent trading.  Like the High Quality Bond Fund, the American Government Fund
may buy and sell investments relatively often, which involves higher brokerage
commissions and other expenses, and may increase the taxes payable by
shareholders.

                                      -18-
<PAGE>

Other investments.  In addition to the fund's main investment strategies of
investing in U.S. government securities, the fund may also buy and sell other
types of investments, such as collateralized mortgage obligations (CMOs) and
interest-only (IO) and principal-only (PO) stripped mortgage-backed investments,
and therefore may be subject to other risks.

                                     General

   
This Prospectus/Proxy Statement is furnished in connection with the proposed
merger of the High Quality Bond Fund into the American Government Fund and the
solicitation of proxies by and on behalf of the Trustees of the High Quality
Bond Fund for use at the Meeting of Shareholders. The Meeting is to be held on
July 1, 1999 at 2:00 p.m. at One Post Office Square, 8th Floor, Boston,
Massachusetts. The Notice of the Meeting, the combined Prospectus/Proxy
Statement and the enclosed form of proxy are being mailed to shareholders on or
about April 15, 1999.
    

Any shareholder giving a proxy has the power to revoke it by mail (addressed to
the Fund's Clerk at the principal office of the High Quality Bond Fund, One Post
Office Square, Boston, Massachusetts 02109) or in person at the Meeting, by
executing a superseding proxy, or by submitting a notice of revocation to the
High Quality Bond Fund. All properly executed proxies received in time for the
Meeting will be voted as specified in the proxy, or, if no specification is
made, FOR the proposal (set forth in Proposal 1 of the Notice of Meeting) to
implement the merger of the High Quality Bond Fund by the transfer of all of its
assets to the American Government Fund in exchange for the Merger Shares and the
assumption by the American Government Fund of all of the liabilities of the High
Quality Bond Fund.

   
As of January 31, 1999, there were outstanding 37,750,724 shares of beneficial
interest of the High Quality Bond Fund. Only shareholders of record on April 1,
1999 will be entitled to notice of and to vote at the Meeting. Each share is
entitled to one vote, with fractional shares voting proportionally.
    

The Trustees of the High Quality Bond Fund know of no matters other than those
set forth herein to be brought before the Meeting. If, however, any other
matters properly come before the Meeting, it is the Trustees' intention that
proxies will be voted on such matters in accordance with the judgment of the
persons named in the enclosed form of proxy.

Proposal regarding approval or disapproval of Merger Transaction and Related
Agreement and Plan of Reorganization

The shareholders of the High Quality Bond Fund are being asked to approve or
disapprove a merger between the High Quality Bond Fund and the American
Government Fund pursuant to an Agreement and Plan of Reorganization between the
Funds, dated as of March __, 1999 (the "Agreement"), a copy of which is attached
to this Prospectus/Proxy Statement as Exhibit A.

The merger is structured as a transfer of all of the assets of the High Quality
Bond Fund to the


                                      -19-
<PAGE>

American Government Fund in exchange for the assumption by the American
Government Fund of all of the liabilities of the High Quality Bond Fund and for
that number of the Class A, Class B and Class M Merger Shares, equal in total
net asset value to the net value of assets transferred to the American
Government Fund, all as more fully described below under "Information about the
merger."

After receipt of the Merger Shares, the High Quality Bond Fund will distribute
the Class A Merger Shares to its Class A shareholders, the Class B Merger Shares
to its Class B shareholders and the Class M Merger Shares to its Class M
shareholders, in proportion to their existing shareholdings in complete
liquidation of the High Quality Bond Fund, and the legal existence of the High
Quality Bond Fund as a separate business trust under Massachusetts law will be
terminated. Each shareholder of the High Quality Bond Fund will receive a number
of full and fractional Class A, Class B, or Class M Merger Shares equal in value
at the date of the exchange to the aggregate value of the shareholder's High
Quality Bond Fund shares.

Prior to the date of the transfer (the "Exchange Date"), the High Quality Bond
Fund will declare a distribution to shareholders which, together with all
previous distributions, will have the effect of distributing to shareholders all
of its investment company taxable income (computed without regard to the
deduction for dividends paid) and net realized capital gains, if any, through
the Exchange Date.

The Trustees have voted unanimously to approve the proposed transaction and to
recommend that shareholders also approve the transaction. The transactions
contemplated by the Agreement and Plan of Reorganization will be consummated
only if approved by the affirmative vote of the holders of 66-2/3% or more of
the outstanding shares of the High Quality Bond Fund entitled to vote.

In the event that this proposal is not approved by the shareholders of the High
Quality Bond Fund, the High Quality Bond Fund will continue to be managed as a
separate fund in accordance with its current investment objectives and policies,
and the Trustees may consider such alternatives as may be in the best interests
of its shareholders.

Background and reasons for the proposed merger

The Trustees of each Fund, including all Trustees who are not "interested
persons" of the Funds, have determined that the reorganization would be in the
best interests of each Fund's shareholders, and that the interests of existing
shareholders of each of the Funds would not be diluted as a result of effecting
the reorganization. The Trustees have unanimously approved the proposed
reorganization and have recommended its approval by shareholders. The American
Government Fund and the High Quality Bond Fund have the same Trustees.

The proposal is the result of a recent review by the funds' investment manager,
Putnam Investment Management, Inc. ("Putnam Management"), of the investment
strategies and position of Putnam Management's fixed income funds. Currently
Putnam Management advises a number of mutual funds investing wholly or
substantially in U.S. government and agency securities and investment grade
corporate debt. As discussed above, while not identical, the American


                                      -20-
<PAGE>

Government Fund and the High Quality Bond Fund have similar investment policies,
each investing at least 65% in U.S. government and agency securities.

In light of the substantial similarity of the funds, Putnam Management advised
the trustees that combining the funds would be in the best interests of
shareholders of both funds. The combined fund would have lower expenses than
either of the existing funds (see "Synopsis, question 5" for a discussion of
expenses). Putnam Management also advised the Trustees that combining the funds
would likely improve sales of the funds, thus offering the opportunity for
further growth and reduction of expenses although there can be no assurance that
the merger will lead to increased sales.

   
Based on their review and Putnam Management's advice, the Trustees have
unanimously approved the proposal. Further in light of the larger size of the
American Government Fund ($1,559,262,662 as of January 31, 1999 versus
$384,970,695 for the High Quality Bond Fund), the Trustees concluded that it
would be preferable for the High Quality Bond Fund to merge into the American
Government Fund.
    

Set forth below is total return information for the Class A shares of the two
Funds for the one year periods ending on the dates stated:

Exchange without recognition of gain or loss for Federal Income Tax purposes. If
a High Quality Bond Fund shareholder were to redeem his or her shares to invest
in another fund, like the American Government Fund, gain or loss would be
recognized by that shareholder for federal income tax purposes. Also, if the
High Quality Bond Fund were liquidated or were reorganized in a taxable
reorganization, the transaction would likely result in a taxable event for its
shareholders. By contrast, the proposed merger will permit the High Quality Bond
Fund's shareholders to exchange their investment for an investment in the
American Government Fund without recognition of gain or loss for federal income
tax purposes. After the merger, shareholders will be free to redeem any or all
of the American Government Fund shares at net asset value at any time, at which
point a taxable gain or loss would be recognized.

<PAGE>

   
Agreement and plan of reorganization.  The proposed merger will be governed by
an Agreement and Plan of Reorganization. The Agreement provides that the
American Government Fund will acquire all of the assets of the High Quality Bond
Fund in exchange for the assumption by the American Government Fund of all of
the liabilities of the High Quality Bond Fund and for the issuance of Class A,
Class B and Class M Merger Shares equal in value to the value of the transferred
assets net of assumed liabilities. The shares will be issued on the next full
business day (the "Exchange Date") following the time as of which the funds'
shares are valued for determining net asset value for the merger (4:00 p.m.
Boston time on July 16, 1999 or such other date as may be agreed upon by the
parties). The following discussion of the Agreement is qualified in its entirety
by the full text of the Agreement, which is attached as Exhibit A to this
Prospectus/Proxy Statement.
    

The High Quality Bond Fund will sell all of its assets to the American
Government Fund, and in exchange, the American Government Fund will assume all
of the liabilities of the High Quality Bond Fund and deliver to the High Quality
Bond Fund (i) a number of full and fractional Class A Merger Shares having an
aggregate net asset value equal to the value of assets of the High Quality Bond
Fund attributable to its Class A shares, less the value of the liabilities of
the High Quality Bond Fund assumed by the American Government Fund attributable
to such Class A shares; (ii) a number of full and fractional Class B Merger
Shares having a net asset value equal to the value of assets of the High Quality
Bond Fund attributable to its Class B shares, less the value of the liabilities
of the High Quality Bond Fund assumed by the American Government Fund
attributable to such Class B shares, and (iii) a number of full and fractional
Class M Merger Shares having a net asset value equal to the value of assets of
the High Quality Bond Fund attributable to its Class M shares, less the value of
the liabilities of the High Quality Bond Fund assumed by the American Government
Fund attributable to such Class M Shares.

Immediately following the Exchange Date, the High Quality Bond Fund will
distribute pro rata to its shareholders of record as of the close of business on
the Exchange Date the full and fractional Merger Shares received by the High
Quality Bond Fund, with Class A Merger Shares being distributed to holders of
Class A shares of the High Quality Bond Fund, Class B Merger Shares being
distributed to holders of Class B shares of the High Quality Bond Fund and Class
M Merger Shares being distributed to holders of Class M shares of the High
Quality Bond Fund. As a result of the proposed transaction, each holder of Class
A, Class B and Class M shares of the High Quality Bond Fund will receive a
number of Class A, Class B and Class M Merger Shares equal in aggregate value at
the Exchange Date to the value of the Class A, Class B and Class M shares,
respectively, of the High Quality Bond Fund held by the shareholder. This
distribution will be accomplished by the establishment of accounts on the share
records of the American Government Fund in the name of such High Quality Bond
Fund shareholders, each account representing the respective number of full and
fractional Class A, Class B and Class M Merger Shares due such shareholder.
New certificates for Merger Shares will be issued only upon written request.

The Trustees of the High Quality Bond Fund have determined that the interests of
the High Quality Bond Fund's shareholders will not be diluted as a result of the
transactions contemplated


                                      -22-
<PAGE>

by the merger, and the Trustees of both funds have determined that the proposed
merger is in the best interests of each fund.

The consummation of the merger is subject to the conditions set forth in the
Agreement. The Agreement may be terminated and the reorganization abandoned at
any time, before or after approval by the shareholders, prior to the Exchange
Date by mutual consent of the American Government Fund and the High Quality Bond
Fund or, if any condition set forth in the Agreement has not been fulfilled and
has not been waived by the party entitled to its benefits, by such party.

The fees and expenses for the transaction are estimated to be $215,000. All fees
and expenses, including legal and accounting expenses, portfolio transfer taxes
(if any) or other similar expenses incurred in connection with the consummation
of the transactions contemplated by the Agreement will be allocated ratably
between the two Funds in proportion to their net assets as of the day of the
transfer, except that the costs of proxy materials and proxy solicitations will
be borne by the High Quality Bond Fund. However, to the extent that any payment
by either Fund of such fees or expenses would result in the disqualification of
the American Government Fund or the High Quality Bond Fund as a "regulated
investment company" within the meaning of Section 851 of the Internal Revenue
Code of 1986, as amended (the "Code"), such fees and expenses will be paid
directly by the party incurring them.

Description of the Merger Shares.  Merger Shares will be issued to the High
Quality Bond Fund's shareholders in accordance with the procedure under the
Agreement as described above. The Merger Shares are Class A, Class B and Class M
shares of the American Government Fund. Investors purchasing Class A and Class M
shares pay a sales charge at the time of purchase, but High Quality Bond Fund
shareholders receiving Class A and Class M Merger Shares in the merger will not
pay a sales charge on such shares. Class A and Class M shares of the American
Government Fund generally are not subject to redemption fees, but such shares
are subject to a 12b-1 fee at the annual rate of 0.25% and 0.50% of the Fund's
average daily net assets attributable to Class A and Class M shares,
respectively. Class B shares of The American Government Fund are sold without a
sales charge, but are subject to a CDSC of up to 5% if redeemed within six years
of purchase. For purposes of determining the CDSC payable on redemption of Class
B Merger Shares received by holders of Class B shares of the High Quality Bond
Fund, such shares will be treated as having been acquired as of the dates such
shareholders originally acquired their Class B shares of the High Quality Bond
Fund. Class B shares are also subject to a 12b-1 fee at the annual rate of 1.00%
of the Fund's average daily net assets attributable to Class B shares. Class B
shares will automatically convert to Class A shares, based on relative net asset
value, approximately eight years after purchase.

Each of the Merger Shares will be fully paid and nonassessable when issued, will
be transferable without restriction, and will have no preemptive or conversion
rights, except that Class B Merger Shares will have the conversion rights
specified above. The Agreement and Declaration of Trust of the American
Government Fund permits the fund to divide its shares, without shareholder
approval, into two or more classes of shares having such preferences and special
or


                                      -23-
<PAGE>

relative rights and privileges as the Trustees may determine. The American
Government Fund's shares are currently divided into three classes--Class A,
Class B and Class M shares.

Under Massachusetts law, shareholders could, under certain circumstances, be
held personally liable for the obligations of the American Government Fund.
However, the Agreement and Declaration of Trust disclaims shareholder liability
for acts or obligations of the American Government Fund and requires that notice
of such disclaimer be given in each agreement, obligation, or instrument entered
into or executed by the American Government Fund or its Trustees. The Agreement
and Declaration of Trust provides for indemnification out of Fund property for
all loss and expense of any shareholder held personally liable for the
obligations of the American Government Fund. Thus, the risk of a shareholder
incurring financial loss on account of shareholder liability is limited to
circumstances in which the American Government Fund would be unable to meet its
obligations. The likelihood of such circumstances is remote. The shareholders of
the High Quality Bond Fund are currently subject to this same risk of
shareholder liability.

Federal income tax consequences.  As a condition to the High Quality Bond Fund's
obligation to consummate the reorganization, the High Quality Bond Fund will
receive an opinion from Ropes & Gray, counsel to the Funds, (which opinion would
be based on certain factual representations and subject to certain
qualifications) to the effect that, on the basis of the existing provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), current
administrative rules and court decisions, for federal income tax purposes:

         (i) The acquisition by the American Government Fund of substantially
         all of the assets of the High Quality Bond Fund solely in exchange for
         Merger Shares and the assumption by the American Government Fund of
         liabilities of the High Quality Bond Fund followed by the distribution
         by the High Quality Bond Fund to its shareholders of Merger Shares in
         complete liquidation of the High Quality Bond Fund, all pursuant to the
         plan of reorganization, constitutes a reorganization within the meaning
         of Section 368(a) of the Code and the High Quality Bond Fund and the
         American Government Fund will each be a "party to a reorganization"
         within the meaning of Section 368(b) of the Code;

         (ii) under Section 361 of the Code, no gain or loss will be recognized
         by the High Quality Bond Fund upon the transfer of its assets and the
         assumption of its liabilities by the American Government Fund or upon
         the distribution of the Merger Shares to the High Quality Bond Fund's
         shareholders in liquidation of the High Quality Bond Fund;

         (iii) under Section 354 of the Code, no gain or loss will be recognized
         by shareholders of the High Quality Bond Fund on the exchange of their
         shares of the High Quality Bond Fund for Merger Shares;

                                      -24-
<PAGE>

         (iv) under Section 358 of the Code, the basis of the Merger Shares
         received by the High Quality Bond Fund's shareholders will be the same
         as the basis of the High Quality Bond Fund shares exchanged therefor;

         (v) under Section 1223(1) of the Code, the holding periods of the
         Merger Shares received by the shareholders of the High Quality Bond
         Fund will include the holding periods of the High Quality Bond Fund
         shares exchanged therefor, provided that at the time of the
         reorganization the High Quality Bond Fund shares are held by such
         shareholders as a capital asset;

         (vi) under Section 1032 of the Code, no gain or loss will be recognized
         by the American Government Fund upon the receipt of assets of the High
         Quality Bond Fund in exchange for Merger Shares and the assumption by
         the American Government Fund of the liabilities of the High Quality
         Bond Fund;

         (vii) under Section 362(b) of the Code, the basis in the hands of the
         American Government Fund of the assets of the High Quality Bond Fund
         transferred to the American Government Fund will be the same as the
         basis of such assets in the hands of the High Quality Bond Fund
         immediately prior to the transfer; and

         (viii) under Section 1223(2) of the Code, the holding periods of the
         assets of the High Quality Bond Fund in the hands of the American
         Government Fund will include the periods during which such assets were
         held by the High Quality Bond Fund.

Capitalization.  The following table shows the capitalization of the Funds as of
January 31, 1999, and on a pro forma combined basis, giving effect to the
proposed acquisition of assets at net asset value as of that date:

Unaudited pro forma combining financial statements of the Funds as of September
30, 1998 and for the twelve month period then ended are included in the
Statement of Additional Information relating to the proposed merger. Because the
Agreement provides that the American Government Fund will be the surviving Fund
following the merger and because the American Government Fund's investment
objectives and policies will remain unchanged, the pro forma combining financial
statements reflect the transfer of the assets and liabilities of the High
Quality Bond Fund to the American Government Fund as contemplated by the
Agreement.

The Trustees of Putnam High Quality Bond Fund, including the independent
trustees, unanimously recommend approval of the Agreement.

Voting information

The American Government Fund will not permit any High Quality Bond Fund
Shareholder holding certificates for High Quality Bond Fund shares at the time
of the merger to receive cash dividends or other distributions, receive
certificates for shares issued in the merger ("Merger Shares"), exchange Merger
Shares for shares of other investment companies managed by Putnam Management, or
pledge or redeem Merger Shares until such certificates for High Quality Bond
Fund shares have been surrendered, or, in the case of lost certificates, an
adequate surety bond has been posted.

   
Required vote. Proxies are being solicited from the High Quality Bond Fund's
shareholders by its Trustees for the Meeting of Shareholders to be held on July
1, 1999 at 2:00 p.m. (the "Meeting"), at One Post Office Square, 8th Floor,
Boston, Massachusetts, or at such later time made necessary by adjournment.
Unless revoked, all valid proxies will be voted in accordance with the
specification thereon or, in the absence of specifications, FOR approval of the
Agreement and Plan of Reorganization. The transactions contemplated by the
Agreement and Plan of Reorganization will be consummated only if approved by the
affirmative vote of the holders of 66-2/3% or more of the outstanding shares of
the High Quality Bond Fund entitled to vote.

Record date, quorum and method of tabulation. Shareholders of record of the High
Quality Bond Fund at the close of business on April 1, 1999 (the "record date")
will be entitled to vote at the Meeting or any adjournment thereof. The holders
of 30% of the shares of the High Quality Bond Fund outstanding at the close of
business on the record date present in person or represented by proxy will
constitute a quorum for the Meeting; however, as noted above, the affirmative
vote of the holders of 66-2/3% or more of the outstanding shares of the High
Quality Bond Fund entitled to vote, is necessary to approve the merger.
Shareholders are entitled to one vote for each share held, with fractional
shares voting proportionally.
    

Votes cast by proxy or in person at the meeting will be counted by persons
appointed by the High Quality Bond Fund as tellers for the Meeting. The tellers
will count the total number of votes cast "for" approval of the proposal for
purposes of determining whether sufficient affirmative votes have been cast. The
tellers will count shares represented by proxies that reflect abstentions and
"broker non-votes" (i.e., shares held by brokers or nominees as to which (i)
instructions have not been received from the beneficial owners or the persons
entitled to vote and (ii) the broker or nominee does not have the discretionary
voting power on a particular matter) as shares that are present and entitled to
vote on the matter for purposes of determining the presence of a quorum.
Abstentions and broker non-votes have the effect of a negative vote on the
proposal.

As of January 31, 1999, the officers and Trustees of the High Quality Bond Fund
as a group beneficially owned less than 1% of the outstanding shares of the High
Quality Bond Fund. To the best of the knowledge of the High Quality Bond Fund,
the following shareholders owned of record or


                                      -27-

beneficially 5% or more of the outstanding shares of the High Quality Bond Fund:

The votes of the shareholders of the American Government Fund are not being
solicited, since their approval or consent is not necessary for this
transaction. As of January 31, 1999, the officers and Trustees of the American
Government Fund as a group beneficially owned less than 1% of the outstanding
shares of the American Government Fund. To the best of the knowledge of the
American Government Fund, the following shareholders beneficially owned 5% or
more of the outstanding shares of the American Government Fund:

Solicitation of proxies.  In addition to soliciting proxies by mail, the
Trustees and employees of Putnam Management, Putnam Fiduciary Trust Company and
Putnam Mutual Funds may solicit proxies in person or by telephone. The High
Quality Bond Fund may also arrange to have votes recorded by telephone. The
telephonic voting procedure is designed to authenticate shareholders'
identities, to allow shareholders to authorize the voting of their shares in
accordance with their instructions and to confirm that their instructions have
been properly recorded. The High Quality Bond Fund has been advised by counsel
that these procedures are consistent with the requirements of applicable law. If
these procedures were subject to a successful legal challenge, such votes would
not be counted at the Meeting. The High Quality Bond Fund is unaware of any such
challenge at this time. Shareholders would be called at the phone number Putnam
Investments has in its records for their accounts, and would be asked for their
Social Security numbers or other identifying information. The shareholders would
then be given an opportunity to authorize their proxies to vote their shares in
accordance with their instructions. To ensure that the shareholders'
instructions have been recorded correctly, they will also receive a confirmation
of their instructions in the mail. A special toll-free number will be available
in the event the information in the confirmation is incorrect.

Shareholders may have the opportunity to vote via the Internet by utilizing a
program provided through ADP Investor Communication Services ("ADP"). The giving
of such a proxy will not affect your right to vote in person should you decide
to attend the Meeting. To vote via the Internet, you will need the 12-digit
"control" number that appears with your proxy materials. To vote via the
Internet, please access ADP on the World Wide Web at www.proxyvote.com. The
Internet voting procedures are designed to authenticate shareholder identities,
to allow shareholders to give their voting instructions, and to confirm that
shareholders' instructions have been recorded properly. Shareholders voting via
the Internet should understand that there may be costs associated with
electronic access, such as usage charges from Internet access providers and
telephone companies, that must be borne by the shareholders.

   
Persons holding shares as nominees will upon request be reimbursed for their
reasonable expenses in soliciting instructions from their principals. The High
Quality Bond Fund has retained at its own expense D.F. King & Co., Inc., 77
Water Street, New York, New York 10005, to aid in the solicitation of
instructions for nominee and registered accounts for a fee of $7,500,
    

                                      -28-
<PAGE>

   
plus reasonable out-of-pocket expenses for mailing and phone costs.

    

Revocation of proxies.  Proxies, including proxies given by telephone, may be
revoked at any time before they are voted, by a written revocation received by
the Clerk of the High Quality Bond Fund, by properly executing a later-dated
proxy or by attending the Meeting and voting in person.

Adjournment.  If sufficient votes in favor of the proposal are not received by
the time scheduled for the Meeting, the persons named as proxies may propose
adjournments of the Meeting for a period or periods of not more than 60 days in
the aggregate to permit further solicitation of proxies. Any adjournment will
require the affirmative vote of a majority of the votes cast on the question in
person or by proxy at the session of the Meeting to be adjourned. The persons
named as proxies will vote in favor of such adjournment those proxies which they
are entitled to vote in favor of the proposal. They will vote against any such
adjournment those proxies required to be voted against the proposal. The High
Quality Bond Fund pays the costs of any additional solicitation and of any
adjourned session.

                                    EXHIBIT A

                      AGREEMENT AND PLAN OF REORGANIZATION

                  This Agreement and Plan of Reorganization (the "Agreement") is
made as of March __, 1999 in Boston, Massachusetts, by and among Putnam American
Government Income Fund, a Massachusetts business trust (the "American Government
Fund"), Putnam High Quality Bond Fund, a Massachusetts business trust (the "High
Quality Bond Fund").

                             PLAN OF REORGANIZATION

(a) The High Quality Bond Fund will sell, assign, convey, transfer and deliver
to the American Government Fund on the Exchange Date (as defined in Section 6)
all of its properties and assets existing at the Valuation Time (as defined in
Section 3(c)). In consideration therefor, the American Government Fund shall, on
the Exchange Date, assume all of the liabilities of the High Quality Bond Fund
existing at the Valuation Time and deliver to the High Quality Bond Fund (i) a
number of full and fractional Class A shares of beneficial interest of the
American Government Fund (the "Class A Merger Shares") having an aggregate net
asset value equal to the value of the assets of the High Quality Bond Fund
attributable to Class A shares of the High Quality Bond Fund transferred to the
American Government Fund on such date less the value of the liabilities of the
High Quality Bond Fund attributable to Class A shares of the High Quality Bond
Fund assumed by the American Government Fund on such date, (ii) a number of full
and fractional Class B shares of beneficial interest of the American Government
Fund (the "Class B Merger Shares") having an aggregate net asset value equal to
the value of the assets of the High Quality Bond Fund attributable to Class B
shares of the High Quality Bond Fund transferred to the American Government Fund
on such date less the value of the liabilities of the High Quality Bond Fund
attributable to Class B shares of the High Quality Bond Fund assumed by the
American Government Fund on such date, and (iii) a number of full and fractional
Class M shares of beneficial interest of the American Government Fund (the
"Class M Merger Shares") having an aggregate net asset value equal to the value
of the assets of the High Quality Bond Fund attributable to Class M shares of
the High Quality Bond Fund transferred to the American Government Fund on such
date less the value of the liabilities of the High Quality Bond Fund
attributable to Class M shares of the High Quality Bond Fund assumed by the
American Government Fund on such date. The Class A Merger Shares, the Class B
Merger Shares, and the Class M Merger Shares shall be referred to collectively
as the "Merger Shares." It is intended that the reorganization described in this
Plan shall be a reorganization within the meaning of Section 368(a)(1) of the
Internal Revenue Code of 1986, as amended (the "Code").

(b) Upon consummation of the transactions described in paragraph (a) of this
Agreement, the High Quality Bond Fund shall distribute in complete liquidation
to its Class A, Class B, and

<PAGE>

Class M shareholders of record as of the Exchange Date Class A, Class B, and
Class M Merger Shares, each shareholder being entitled to receive that
proportion of such Class A, Class B or Class M Merger Shares that the number of
Class A, Class B, or Class M shares of beneficial interest of the High Quality
Bond Fund held by such shareholder bears to the number of such Class A, Class B
or Class M shares of the High Quality Bond Fund outstanding on such date.
Certificates representing the Merger Shares will be issued only if the
shareholder so requests.

                                    AGREEMENT

The American Government Fund and the High Quality Bond Fund agree as follows:

1. Representations and warranties of the American Government fund.  The American
Government Fund represents and warrants to and agrees with the High Quality Bond
Fund that:

(a) The American Government Fund is a business trust duly established and
validly existing under the laws of The Commonwealth of Massachusetts, and has
power to own all of its properties and assets and to carry out its obligations
under this Agreement. The American Government Fund is not required to qualify as
a foreign association in any jurisdiction. The American Government Fund has all
necessary federal, state and local authorizations to carry on its business as
now being conducted and to carry out this Agreement.

(b) The American Government Fund is registered under the Investment Company Act
of 1940, as amended (the "1940 Act"), as an open-end management investment
company, and such registration has not been revoked or rescinded and is in full
force and effect.

(c) A statement of assets and liabilities, statement of operations, statement of
changes in net assets and schedule of investments (indicating their market
values) of the American Government Fund for the fiscal year ended September 30,
1998, such statements and schedule having been audited by PricewaterhouseCoopers
LLP, independent accountants, have been furnished to the High Quality Bond Fund.
Such statements of assets and liabilities and schedule of investments fairly
present the financial position of the American Government Fund as of September
30, 1998 and such statements of operations and changes in net assets fairly
reflect the results of its operations and changes in net assets for the period
covered thereby in conformity with generally accepted accounting principles.

(d) The prospectus and statement of additional information dated January 30,
1999, previously furnished to the High Quality Bond Fund, and any amendment or
supplement thereto or any superseding prospectus or statement of additional
information in respect thereof in effect prior to the Exchange Date, which will
be furnished to the High Quality Bond Fund (collectively, the "American
Government Fund Prospectus") do not and will not, as of the relevant date
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; provided however, that the

                                      -2-
<PAGE>

American Government Fund makes no representation or warranty as to any
information in the American Government Fund Prospectus that does not
specifically relate to the American Government Fund.

(e) There are no material legal, administrative or other proceedings pending or,
to the knowledge of the American Government Fund, threatened against the
American Government Fund which assert liability or may, if successfully
prosecuted to their conclusion, result in liability on the part of the American
Government Fund, other than as have been disclosed in the American Government
Fund Prospectus.

(f) The American Government Fund has no known liabilities of a material nature,
contingent or otherwise, other than those shown as belonging to it on its
statement of assets and liabilities as of September 30, 1998 and those incurred
in the ordinary course of the American Government Fund's business as an
investment company since such date.

(g) No consent, approval, authorization or order of any court or governmental
authority is required for the consummation by the American Government Fund of
the transactions contemplated by this Agreement, except such as may be required
under the Securities Act of 1933, as amended (the "1933 Act"), the Securities
Exchange Act of 1934, as amended (the "1934 Act"), the 1940 Act, state
securities or blue sky laws (which term as used herein shall include the laws of
the District of Columbia and of Puerto Rico) or the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "H-S-R Act").

(h) The registration statement (the "Registration Statement") filed with the
Securities and Exchange Commission (the "Commission") by the American Government
Fund on Form N-14 relating to the Merger Shares issuable hereunder, and the
proxy statement of the High Quality Bond Fund included therein (the "Proxy
Statement"), on the effective date of the Registration Statement (i) will comply
in all material respects with the provisions of the 1933 Act, the 1934 Act and
the 1940 Act and the rules and regulations thereunder and (ii) will not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; and at the time of the shareholders' meeting referred to in Section
7(a) and at the Exchange Date, the prospectus contained in the Registration
Statement of which the Proxy Statement is a part (the "Prospectus"), as amended
or supplemented by any amendments or supplements filed or requested to be filed
with the Commission by the High Quality Bond Fund, will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading;
provided however, that none of the representations and warranties in this
subsection shall apply to statements in or omissions from the Registration
Statement, the Prospectus or the Proxy Statement made in reliance upon and in
conformity with information furnished by the High Quality Bond Fund for use in
the Registration Statement, the Prospectus or the Proxy Statement.

                                      -3-
<PAGE>

(i) There are no material contracts outstanding to which the American Government
Fund is a party, other than as disclosed in the Registration Statement, the

Fund at the Exchange Date and shall not be separately valued unless the
securities in respect of which such distribution is made shall have gone "ex"
such distribution prior to the Valuation Time, in which case any such
distribution which remains unpaid at the Exchange Date shall be included in the
determination of the value of the assets of the High Quality Bond Fund acquired
by the American Government Fund.

   
(c) The Valuation Time shall be 4:00 p.m. Boston time on July 16, 1999 or such

of the High Quality Bond Fund by redelivering such certificates to the American

shareholder), receive certificates representing the Merger Shares, exchange the

his or her outstanding High Quality Bond Fund certificates or, in the event of
lost, stolen, or destroyed certificates, posted adequate bond. In the event that
a shareholder shall not be permitted to receive dividends and other

Fund will, at its expense, request the shareholders of the High Quality Bond
Fund to surrender their outstanding High Quality Bond Fund certificates, or post
adequate bond, as the case may be.

losses, claims, damages and liabilities at any time imposed upon or reasonably
incurred by any one or more of the Indemnified Parties in connection with,
arising out of, or resulting from any claim, action, suit or proceeding in which
any one or more of the Indemnified Parties may be involved or with which any one
or more of the Indemnified Parties may be threatened by reason of any untrue
statement or alleged untrue statement of a material fact relating to the High
Quality Bond Fund contained in the Registration Statement, the Prospectus or the
Proxy Statement or any amendment or supplement to any of the foregoing, or
arising out of or based upon the omission or alleged omission to state in any of
the foregoing a material fact relating to the High Quality Bond Fund required to
be stated therein or necessary to make the statements relating to the High
Quality Bond Fund therein not misleading, including, without limitation, any
amounts paid by any one or more of the Indemnified Parties in a reasonable
compromise or settlement of any such claim, action, suit or proceeding, or
threatened claim, action, suit or proceeding made with the consent of the High
Quality Bond Fund. The Indemnified Parties will notify the High Quality Bond
Fund in writing within ten days after the receipt by any one or more of the
Indemnified Parties of any notice of legal process or any suit brought against
or claim made against such Indemnified Party as to any matters covered by this
Section 10(a). The High Quality Bond Fund shall be entitled to participate at
its own expense in the defense of any claim, action, suit or proceeding covered
by this Section 10(a), or, if it so elects, to assume at its expense by counsel
satisfactory to the Indemnified Parties the defense of any such claim, action,

of any such

                                      -17-
<PAGE>

claim, action, suit or proceeding at their expense. The High Quality Bond Fund's
obligation under this Section 10(a) to indemnify and hold harmless the
Indemnified Parties shall constitute a guarantee of payment so that the High
Quality Bond Fund will pay in the first instance any expenses, losses, claims,
damages and liabilities required to be paid by it under this Section 10(a)
without the necessity of the Indemnified Parties' first paying the same.

(b) The American Government Fund will indemnify and hold harmless, out of the
assets of the American Government Fund but no other assets, the High Quality
Bond Fund, its trustees and its officers (for purposes of this subparagraph, the
"Indemnified Parties") against any and all expenses, losses, claims, damages and
liabilities at any time imposed upon or reasonably incurred by any one or more
of the Indemnified Parties in connection with, arising out of, or resulting from
any claim, action, suit or proceeding in which any one or more of the
Indemnified Parties may be involved or with which any one or more of the
Indemnified Parties may be threatened by reason of any untrue statement or
alleged untrue statement of a material fact relating to the American Government
Fund contained in the Registration Statement, the Prospectus or the Proxy
Statement, or any amendment or supplement to any thereof, or arising out of, or
based upon, the omission or alleged omission to state in any of the foregoing a
material fact relating to the American Government Fund required to be stated
therein or necessary to make the statements relating to the American Government
Fund therein not misleading, including without limitation any amounts paid by
any one or more of the Indemnified Parties in a reasonable compromise or
settlement of any such claim, action, suit or proceeding, or threatened claim,
action, suit or proceeding made with the consent of the American Government
Fund. The Indemnified Parties will notify the American Government Fund in
writing within ten days after the receipt by any one or more of the Indemnified
Parties of any notice of legal process or any suit brought against or claim made
against such Indemnified Party as to any matters covered by this Section 10(b).
The American Government Fund shall be entitled to participate at its own expense
in the defense of any claim, action, suit or proceeding covered by this Section
10(b), or, if it so elects, to assume at its expense by counsel satisfactory to
the Indemnified Parties the defense of any such claim, action, suit or
proceeding, and, if the American Government Fund elects to assume such defense,
the Indemnified Parties shall be entitled to participate in the defense of any
such claim, action, suit or proceeding at their own expense. The American
Government Fund's obligation under this Section 10(b) to indemnify and hold
harmless the Indemnified Parties shall constitute a guarantee of payment so that
the American Government Fund will pay in the first instance any expenses,
losses, claims, damages and liabilities required to be paid by it under this
Section 10(b) without the necessity of the Indemnified Parties' first paying the
same.

11. No broker, etc.  Each of the High Quality Bond Fund and the American
Government Fund represents that there is no person who has dealt with it who by
reason of such dealings is entitled to any broker's or finder's or other similar
fee or commission arising out of the transactions contemplated by this
Agreement.

                                      -18-

12. Termination.  The High Quality Bond Fund and the American Government Fund
may, by mutual consent of their trustees, terminate this Agreement, and the High
Quality Bond Fund or the American Government Fund, after consultation with
counsel and by consent of their trustees or an officer authorized by such
trustees, may waive any condition to their respective obligations hereunder. If
the transactions contemplated by this Agreement have not been substantially
completed by October 31, 1999, this Agreement shall automatically terminate on
that date unless a later date is agreed to by the High Quality Bond Fund and the
American Government Fund.

13. Rule 145.  Pursuant to Rule 145 under the 1933 Act, the American Government
Fund will, in connection with the issuance of any Merger Shares to any person
who at the time of the transaction contemplated hereby is deemed to be an
affiliate of a party to the transaction pursuant to Rule 145(c), cause to be
affixed upon the certificates issued to such person (if any) a legend as
follows:

     "THESE SHARES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED, AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED EXCEPT TO PUTNAM
     AMERICAN GOVERNMENT INCOME FUND OR ITS PRINCIPAL UNDERWRITER UNLESS (I) A
     REGISTRATION STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, OR (II) IN THE OPINION OF COUNSEL
     REASONABLY SATISFACTORY TO PUTNAM AMERICAN GOVERNMENT INCOME FUND SUCH
     REGISTRATION IS NOT REQUIRED."

and, further, the American Government Fund will issue stop transfer instructions
to the American Government Fund's transfer agent with respect to such shares.
The High Quality Bond Fund will provide the American Government Fund on the
Exchange Date with the name of any High Quality Bond Fund shareholder who is to
the knowledge of the High Quality Bond Fund an affiliate of the High Quality
Bond Fund on such date.

14. Covenants, etc. deemed material.  All covenants, agreements, representations
and warranties made under this Agreement and any certificates delivered pursuant
to this Agreement shall be deemed to have been material and relied upon by each
of the parties, notwithstanding any investigation made by them or on their
behalf.

15. Sole agreement; amendments.  This Agreement supersedes all previous
correspondence and oral communications between the parties regarding the subject
matter hereof, constitutes the only understanding with respect to such subject
matter, may not be changed except by a letter of agreement signed by each party
hereto, and shall be construed in accordance with and governed by the laws of
The Commonwealth of Massachusetts.

                                       and

                          Putnam High Quality Bond Fund

                     Proforma Combining Financial Statements

                                   (Unaudited)

The accompanying unaudited proforma combining statements of investment
portfolios and assets and liabilities assumes that the exchange described in the
next paragraph occurred as of September 30, 1998, and the unaudited proforma
combining statement of operations for the twelve months ended September 30, 1998
presents the results of operations of Putnam American Government Income Fund
(the "American Government Fund") as if the combination with Putnam High Quality
Bond Fund (the "High Quality Bond Fund") had been consummated at October 1,
1997. The proforma results of operations are not necessarily indicative of
future operations or the actual results that would have occurred had the
combination been consummated at October 1, 1997. The historical statements have
been derived from the American Government Fund's books and records utilized in
calculating daily net asset value at September 30, 1998, and for the twelve
month period then ended.

The proforma statements give effect to the proposed transfer of all of the
assets of the High Quality Bond Fund to the American Government Fund in exchange
for the assumption by the American Government Fund of all of the liabilities of
the High Quality Bond Fund and for a number of the American Government Fund's
shares equal in value to the value of the net assets of the High Quality Bond
Fund's transferred to the American Government Fund. Under generally accepted
accounting principles, the historical cost of investment securities will be
carried forward to the surviving entity and the results of operations of the
American Government Fund for pre-combination periods will not be restated. The
proforma statement of operations does not reflect the expenses of either fund in
carrying out its obligations under the Agreement and Plan of Reorganization.

The unaudited proforma combining statements should be read in conjunction with
the separate financial statements of the American Government Fund and the High
Quality Bond Fund incorporated by reference in this statement of additional
information.

                               September 30, 1998


The proforma adjustments to these proforma financial statements are comprised of
the following:

     (A) Elimination and reduction of duplicative expenses as a result of the
         merger.

     (B) $145,000 relates to proxy costs which will be borne by the Putnam High
         Quality Bond Fund. The other $70,000 consists of $50,000 of legal
         costs and $20,000 of accounting costs. These are related merger costs
         which will be allocated ratably between the two funds upon
         consummation of the merger.

     (C) Issuance of class A, class B and class M shares of Putnam American
         Government Income Fund to the holders of class A, class B and class M
         shares of Putnam High Quality Bond Fund.

          prospectus which is a part of this Registration Statement by any
          person or party who is deemed to be an underwriter within the meaning
          of Rule 145(c) under the Act, the reoffering prospectus will contain
          the information called for by the applicable registration form for
          reofferings by persons who may be deemed underwriters, in addition to
          the information called for by the other items of the applicable form.

          the amendment is effective, and that, in determining any liability
          under the Act, each post-effective amendment shall be deemed to be a
          new Registration Statement for the securities offered therein, and the

          We have acted as counsel to Putnam American Government Income Fund
(the "Fund"), in connection with the Registration Statement of the Fund on Form
N-14 (the "Registration Statement"), under the Securities Act of 1933, as
amended (the "Act"), relating to the proposed combination of the Fund with
Putnam High Quality Bond Fund (the "High Quality Bond Fund"), and the issuance
of shares of the Fund in connection therewith (the "Shares"), all in accordance
with the terms of the Agreement and Plan of Reorganization between the Fund and
the High Quality Bond Fund dated as of March __, 1999 (the "Agreement").

          We have examined the Fund's Agreement and Declaration of Trust on file
in the office of the Secretary of State of The Commonwealth of Massachusetts and
the Clerk of the City of Boston and the Fund's By-Laws, as amended, and are
familiar with the actions taken by the Fund's Trustees in connection with the
issuance and sale of the Shares. We have also examined such other documents and
records as we have deemed necessary for the purposes of this opinion.

     Based upon the foregoing, we are of the opinion that:

1.   The Trust is a duly organized and validly existing unincorporated
     association under the laws of The Commonwealth of Massachusetts and is
     authorized to issue an unlimited number of its shares of beneficial
     interest.

2.   The Shares have been duly authorized and, when issued in accordance with
     the Agreement, will be validly issued, fully paid, and nonassessable by the
     Fund.

          The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Fund.
However, the Agreement and Declaration of Trust disclaims shareholder liability
for acts or obligations of the Fund and requires that notice of such disclaimer
be given in each note, bond, contract, instrument, certificate, or undertaking
entered into or executed by the Trust or its Trustees. The Agreement and
Declaration of Trust
                                      -10-
<PAGE>

provides for indemnification out of the property of the Fund for all loss and
expense of any shareholder of the Fund held personally liable solely by reason
of his being or having been a shareholder. Thus, the risk of a shareholder's
incurring financial loss on account of being a shareholder is limited to
circumstances in which the Fund itself would be unable to meet its obligations.

     We understand that this opinion is to be used in connection with the
registration of the Shares for offering and sale pursuant to the Act. We consent
to the filing of this opinion with and as part of the Registration Statement and
to the references to our firm in the related prospectus under the caption
"Information about the merger -- Federal income tax consequences."

                                Very truly yours,

                                Ropes & Gray

Ladies and Gentlemen:

     We have acted as counsel in connection with the Agreement and Plan of
Reorganization dated as of ______, 1999 (the "Agreement"), between Putnam
American Government Income Fund ("Acquiring Fund"), a Massachusetts business
trust, and Putnam High Quality Bond Fund ("Target Fund"), a Massachusetts
business trust. The Agreement describes a proposed transaction (the
"Transaction") to occur on ______, 1999, or such other date as may be decided by
the Trust (the "Exchange Date"), pursuant to which Acquiring Fund will acquire
substantially all of the assets of Target Fund in exchange for shares of
beneficial interest in Acquiring Fund (the "Acquiring Fund Shares") and the
assumption by Acquiring Fund of all of the liabilities of Target Fund following
which the Acquiring Fund Shares received by Target Fund will be distributed by
Target Fund to its shareholders in liquidation and termination of Target Fund.
This opinion as to certain federal income tax consequences of the Transaction is
furnished to you pursuant to Sections 8(g) and 9(g) of the Agreement.
Capitalized terms not defined herein are defined in the Agreement.

     Target Fund is a series of the Trust which is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end
management investment company. Shares of Target Fund are redeemable at net asset
value at each shareholder's option. Target Fund has elected to be a regulated
investment company for federal income tax purposes under Section 851 of the
Internal Revenue Code of 1986, as amended (the "Code").

     Acquiring Fund is a series of the Trust which is registered under the 1940
Act as an open-end management investment company. Shares of Acquiring Fund are
redeemable at net asset value at each shareholder's option.

     For purposes of this opinion, we have considered the Agreement, the Proxy
Statement, the Registration Statement (including the items incorporated by
reference therein), and such other items as we have deemed necessary to render
this opinion. In addition, you provided us with a letter dated as of the date
hereof, representing as to certain facts, occurrences and information upon which
you have indicated that we may rely in rendering this opinion (whether or not
contained or reflected in the documents and items referred to above).

     Based on the foregoing representations and our review of the documents and
items referred to above, we are of the opinion that for federal income tax
purposes:

      (i)    The Transaction will constitute a reorganization within the meaning
             of Section 368(a) of the Code. The Target Fund and the Acquiring
             Fund will each be a "party to a reorganization" within the meaning
             of Section 368(b) of the Code;

      (ii)   No gain or loss will be recognized by Target Fund upon the transfer
             of Target Fund's assets to Acquiring Fund in exchange for Acquiring
             Fund Shares and the assumption by Acquiring Fund of the liabilities
             of Target Fund, or upon the distribution of Acquiring Fund Shares
             by Target Fund to its shareholders in liquidation;

      (iii)  No gain or loss will be recognized by the Target Fund shareholders
             upon the exchange of their Target Fund Shares for Acquiring Fund
             Shares;

      (iv)   The basis of Acquiring Fund Shares a Target Fund shareholder
             receives in connection with the Transaction will be the same as the
             basis of his or her Target Fund Shares exchanged therefor;

      (v)    A Target Fund shareholder's holding period for his or her Acquiring
             Fund Shares will be determined by including the period for which he
             or she held the Target Fund Shares exchanged therefor, provided
             that he or she held such Target Fund Shares as capital assets;

      (vi)   No gain or loss will be recognized by Acquiring Fund upon the
             receipt of the assets of Target Fund in exchange for Acquiring Fund
             Shares and the assumption by Acquiring Fund of the liabilities of
             Target Fund;

      (vii)  The basis in the hands of Acquiring Fund of the assets of Target
             Fund transferred to Acquiring Fund in the Transaction will be the
             same as the basis of such assets in the hands of Target Fund
             immediately prior to the transfer; and

      (viii) The holding periods of the assets of Target Fund in the hands of
             Acquiring Fund will include the periods during which such assets 
             were held by Target Fund.
