                               PROXY STATEMENT
                        ANNUAL MEETING OF STOCKHOLDERS
                                MARCH 12, 1999
                        ------------------------------

    This Proxy Statement is furnished in connection with the solicitation of
proxies on behalf of the Board of Directors of Prospect Street High Income
Portfolio Inc., a Maryland corporation (the "Fund"), for use at the Fund's
Annual Meeting of Stockholders (the "Annual Meeting") to be held at 60 State
Street, 37th Floor, Boston, Massachusetts 02109, on March 12, 1999 at 10:00
a.m., and at any and all adjournments thereof, for the purposes set forth in
the accompanying Notice of Annual Meeting dated January 6, 1999. The Fund is a
registered investment company under the Investment Company Act of 1940, as
amended (the "1940 Act").

   
    This Proxy Statement and the accompanying Notice of Annual Meeting and
form of proxy will be first sent to stockholders on or about January 6, 1999.
The Board of Directors has fixed the close of business on December 29, 1998 as
the record date for the determination of stockholders entitled to notice of
and to vote at the Annual Meeting. As of the record date, 19,821,334 shares of
the Fund's Common Stock, $.03 par value per share (the "Common Stock"), were
issued and outstanding. Holders of Common Stock have one vote per share on all
matters submitted to stockholders. To the Fund's knowledge, no person
beneficially owned shares of the Fund representing more than five percent of
the total voting power of all outstanding shares at December 29, 1998. The
Board of Directors is authorized by the Fund's Articles of Incorporation to
issue preferred stock in one or more series without shareholder approval, but
no such class is currently outstanding.

    Shares of Common Stock represented by properly executed proxies with
respect to which a vote is withheld, an abstention is indicated, or a broker
does not vote will be treated as shares that are present and entitled to vote
for purposes of determining a quorum. However, under applicable Maryland law,
abstentions and broker non-votes will not be treated as having been voted for
purposes of determining the approval of Proposal 2 and thus will have the
effect of a vote against such Proposal.
    

    If the accompanying form of proxy is properly executed and returned in
time to be voted at the Annual Meeting, the shares covered thereby will be
voted in accordance with the instructions marked thereon by the stockholder.
Executed proxies that are unmarked will be voted (1) FOR the election of the
applicable nominees named herein as Directors of the Fund, (2) FOR approval of
a proposal to adopt a new Advisory Agreement which would amend the current
0.50% to 0.65% tiered advisory fee structure and would increase the annual
advisory fee to 0.70% of the Fund's average annual net assets up to and
including $200,000,000 and 0.65% of the excess of such managed assets over
$200,000,000, (3) FOR the proposal to ratify the selection of Arthur Andersen
LLP as independent public accountants of the Fund for the fiscal year ending
October 31, 1999, and (4) in the discretion of the persons named as proxies in
connection with any other matter which may properly come before the Annual
Meeting or any adjournment thereof. The Board of Directors does not know of
any matter to be considered at the Annual Meeting other than the matters
referred to above. A stockholder may revoke his or her proxy prior to its use
by appearing at the Annual Meeting and voting in person, by giving written
notice of such revocation to the Secretary of the Fund or by returning a
subsequently dated proxy.

    Shares of Common Stock representing a majority of the votes entitled to be
cast shall constitute a quorum at the Annual Meeting. In the event a quorum is
not present at the Annual Meeting or in the event a quorum is present at the
Annual Meeting but sufficient votes to approve any of the proposals are not
received, the persons named as proxies may propose one or more adjournments of
the Annual Meeting to permit further solicitation of proxies. A stockholder
vote may be taken on one or more of the proposals in this Proxy Statement
prior to such adjournment if sufficient votes have been received and such vote
is otherwise appropriate. Any such adjournment will require the affirmative
vote of a majority of those shares present at the Annual Meeting in person or
by proxy.

   
    In addition to solicitation of proxies by mail, officers of the Fund and
officers and regular employees of Prospect Street Investment Management Co.,
Inc. (the "Manager"), affiliates of the Manager or other representatives of
the Fund may also solicit proxies by telephone or telegraph or in person. The
Fund has also retained Corporate Investor Communications, Inc., a proxy
solicitation firm to assist in the solicitation of proxies. The costs of
retaining such firm, which the Fund does not anticipate will exceed $20,000,
will depend upon the amount and type of services rendered. The costs of proxy
solicitation and expenses incurred in connection with preparing this Proxy
Statement and its enclosures will be paid by the Fund.
    

                            THE INVESTMENT ADVISER

    Prospect Street Investment Management Co., Inc., with its principal office
at 60 State Street, Boston, MA 02109, has served as the investment adviser to
the Fund since its inception in November 1988.

nominees as Directors of the Fund, to serve as such until the next annual

duly elected and qualified. All nominees named below are presently serving as
Directors of the Fund. All shares represented by valid proxies will be voted
in the election of Directors for the applicable nominees named below, unless
authority to vote for a particular nominee is withheld. Each nominee has
agreed to serve as a Director if elected. If any such nominee is not available
for election at the time of the Annual Meeting, the persons named as proxies
will vote for such substitute nominee as the Board of Directors may recommend.

    In accordance with resolutions adopted by the Board of Directors, and

SHARE OWNERSHIP AND CERTAIN BENEFICIAL OWNERS
    As far as is known to the Fund, no person owned beneficially five percent
or more of the outstanding shares of Common Stock of the Fund on December 29,
1998. The Depository Trust Company ("DTC") holds of record 90% of the
outstanding shares of Common Stock. As far as is known to the Fund, no person
other than DTC, owned of record or beneficially, shares of the Fund
representing more than five percent of the voting power of the Fund's
outstanding shares. The Manager of the Fund beneficially owns 30,451 shares of
Common Stock.

REQUIRED VOTE
    The election of each of the nominees for Director requires the affirmative
vote of the holders of a plurality of the common stock of the Fund present and
voting at the Annual Meeting. Pursuant to the Articles of Incorporation,
holders of the Common Stock have voting rights of one vote per share.
Abstentions will not be counted as votes cast and will have no effect on the
result of the vote, although abstentions will count towards the presence of a
quorum. Under the Articles of Incorporation and the 1940 Act, the holders of
the Common Stock are entitled to elect seven Directors (at least four of whom
are not "interested persons" as defined in the 1940 Act).

    THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE ELECTION
OF THE SEVEN NOMINEES TO THE FUND'S BOARD OF DIRECTORS.

                                  PROPOSAL 2

                      APPROVAL OF NEW ADVISORY AGREEMENT

DESCRIPTION OF PROPOSED NEW ADVISORY AGREEMENT

    In late November 1998, the Manager requested an increase in the advisory
fee and the Board members reviewed various factors pertaining to such request.
Accordingly, on December 14, 1998, the Noninterested Directors and the full
Board of Directors, further considered all of the information presented by the
Adviser and approved (subject to stockholder approval) a new Advisory
Agreement under which the annual fee payable monthly to the Manager would be
increased to 0.70% (on an annual basis) of the average weekly value of the
total assets of the Fund ("Managed Assets"), less accrued and unpaid dividends
on any outstanding shares of preferred stock and less accrued liabilities
(excluding the principal amount of the Fund's "senior securities representing
indebtedness" as defined in the 1940 Act, not to exceed $75 million (the
"Principal Debt Exclusion"), and excluding the liquidation preference of any
outstanding shares of preferred stock or other senior securities) up to and
including $200,000,000 of such managed assets and an annual rate of 0.65% of
the excess of such managed assets over $200,000,000. Currently, the Principal
Debt Exclusion is $50 million and the Manager receives a monthly advisory fee
equal to 0.65% up to and including $175,000,000 of managed assets, 0.55% on
the next $50,000,000 of managed assets and 0.50% of the excess of managed
assets over $225,000,000. As so calculated, such Managed Assets are
hereinafter referred to as the "average net assets" of the Fund.

    There are no other changes being proposed to be made in the existing
Advisory Agreement and accordingly the new Agreement will otherwise be
virtually identical to the existing one. The proposed $25 million increase in
the Principal Debt Exclusion will have no immediate effect on the actual
advisory fee since the maximum amount of senior indebtedness under an existing
revolving credit agreement is currently $50 million, of which $40 million is
outstanding.

    In requesting a fee increase, the Manager referred the Board to, among
other things, the increasing research and analysis burden resulting from the
growth of the high yield market from $250 Billion on January 1, 1994 to
approximately $600 Billion as of June 30, 1998, and the increased
administrative costs and increased complexity of administering the Fund.
According to "1998 Leveraged Finance Annual Review" of Donaldson, Lufkin &
Jenrette, Inc., the "high-yield" new issue market has increased from
approximately $50 Billion in calendar 1993 to $126 Billion in 1997.

    According to current information derived by the Manager from Lipper
Analytical Services regarding closed-end investment companies, the current
advisory fee is lower than the average charged by other leveraged closed-end
funds which invest primarily in high yield securities as does the Fund. The
proposed fee will be closer to the approximate 0.71% average of the Fund's
peer group.

    The table below compares actual fees incurred under the existing Advisory
Agreement with the fees that would have been payable under the proposed
Agreement during the last fiscal year of the Fund.

COMPARATIVE FEE TABLE
    The table below compares the ratio of management fee, other expenses and
total operating expenses to the average net assets of the Fund with respect to
the current fee and proposed fee. The table assumes average net assets for the
Fund of $225,000,000 and senior borrowing of $40,000,000:

    The following example illustrates the expenses on a $1,000 investment
under the existing and proposed fee schedule, and the total Fund operating
expenses stated above, assuming (1) a 5% annual return and (2) $225,000,000 of
average net assets in the Fund upon which the advisory fee is calculated.

    The purpose of this example and the foregoing Comparative Fee Table is to
assist investors in understanding the various costs and expenses of investing
in shares of the Fund. The example above should not be considered a
representation of past or future expenses of the Fund. Actual expenses may
vary from year to year and may be higher or lower than those shown above.

    The Fund's audited ratio of operating expenses (exclusive of interest) to
average net assets for the year ended October 31, 1998 was 1.20% and if the
proposed Agreement had been in effect such ratio would have been 1.28%. The
audited ratio of operating expenses (inclusive of interest) to average net
assets for the year ended October 31, 1998 was 2.18% and if the proposed
Agreement had been in effect such ratio would have been 2.26%. The average
ratio of operating expenses (inclusive of interest) to average net assets of
all other leveraged "high yield" closed-end funds was 2.04% during the last
fiscal year of such funds according to information derived by the Manager from
Lipper Analytical Services, Inc.

   
    The Board of Directors has determined that the compensation to be paid to
the Manager under the proposed Agreement is fair and reasonable. In approving
the proposed Agreement and recommending its approval by stockholders, the
Directors of the Fund, including the Noninterested Directors, considered the
best interests of stockholders of the Fund and took into account all such
factors they deemed relevant. The factors considered by the Noninterested
Directors included the nature, quality and extent of the services furnished by
the Manager to the Fund since its inception, and particularly the last five
fiscal years; the necessity of the Manager maintaining and enhancing its
ability to retain and attract capable personnel to serve the Fund; the
experience of the Manager in "high-yield" investing and particularly in
managing the Fund; the effect of the proposed investment advisory fee increase
on the expense ratio of the Fund; comparative data as to investment
performance, advisory fees and expense ratios, particularly fee and expense
ratios of funds with similar investment objectives; the advantages and
possible disadvantages to the Fund of having an adviser which does not
currently serve other investment companies; the continuance of appropriate
incentives to assure that the Manager will continue to furnish high quality
services to the Fund; and the advisability of modifying the current tiered fee
structure under which the fee would be reduced upon reaching certain asset
levels. Of the factors set forth above, comparative data as to investment
performance was the primary factor and the other factors were considered
relatively equally by the Board of Directors.
    

    Until such time as the new Advisory Agreement has been approved by
stockholders, the fee payable to the Manager will continue as described above.
The present Advisory Agreement will continue in effect until February 28, 2000
if this Proposal No.2 is not adopted. The present Advisory agreement was last
approved by the Directors on December 14, 1998 and by the stockholders on
March 1, 1994. In the event of the approval of the proposed new Agreement by
the stockholders, such new Agreement will be effective on March 12, 1999 and
will have a two-year term expiring on March 11, 2001.

    The Board of Directors recommends that stockholders vote FOR approval of
the New Advisory Agreement.

    Under both the existing and the proposed Advisory Agreements the Fund
bears all costs of its operation other than those incurred by the Manager
under the Advisory Agreement. In particular, the Fund pays investment advisory
fees, fees and expenses associated with the Fund's administration, record
keeping and accounting, fees and expenses for the custodian of the Fund's
assets and the legal, accounting and auditing fees, taxes, expenses of
preparing prospectuses and shareholder reports, registration fees and
expenses, fees and expenses for the transfer and dividend disbursing agent,
the compensation and expenses of the Directors who are not otherwise employed
by or affiliated with the Manager or any of its affiliates, and any
extraordinary expenses. The Manager will reimburse the Fund for any expenses
(excluding brokerage commissions, interest, taxes and litigation expenses)
paid or incurred by the Fund in any year in excess of the most restrictive
expense limitation, which is imposed by any state and to which the Fund is
then subject, if any. The Fund is not known to be subject to any state expense
limitations. Under both Advisory Agreements, the Manager provides the Fund
with office space, facilities and business equipment and provides the services
of executive and clerical personnel for administering certain of the other
affairs of the Fund. The Manager compensates Directors of the Fund if such
persons are employed by the Manager or its affiliates.

    The proposed Advisory Agreement will remain in effect until March 11, 2001
and will continue in effect from year to year (as would the existing
Agreement) as long as it is approved at least annually (i) by either the Board
of Directors of the Fund or by a vote of a majority of the outstanding voting
securities of the Fund (as defined in the 1940 Act) and (ii) in either case by
a majority of the Directors of the Fund who are not parties to the Advisory
Agreement or interested persons of any such party, cast in person at a meeting
called for the purpose of voting on such approval. Either the current or the
proposed Advisory Agreement may be terminated at any time, without payment of
any penalty, by vote of the Board of Directors, by vote of the majority of the
outstanding voting securities of the Fund (as defined in the 1940 Act and as
further described below), or by the Manager, in each case on not more than
sixty (60) days' nor less than thirty (30) days' prior written notice, and
will terminate automatically in the event of its assignment.

    Under the 1940 Act, approval of the new Advisory Agreement (this Proposal
No. 2) will require a vote of a majority of the outstanding voting securities
of the Fund (currently only Common Stock), which means the lesser of either
(a) the vote of 67% or more of the shares of the applicable class or classes
present at the relevant meeting, if the holders of more than 50% of the
outstanding shares of the applicable class or classes are present or
represented by proxy, or (b) the vote of more than 50% of the outstanding
shares of the applicable class or classes. UNDER APPLICABLE MARYLAND LAW, IN
DETERMINING WHETHER THIS PROPOSAL NO. 2 HAS RECEIVED THE REQUISITE NUMBER OF
AFFIRMATIVE VOTES, ABSTENTIONS AND BROKER NON-VOTES WILL NOT BE COUNTED AND
THUS WILL HAVE THE EFFECT OF A VOTE AGAINST SUCH PROPOSALS.

    Based upon information furnished by the Manager, the Board of Directors is
not aware of any financial condition of the Manager which is reasonably likely
to impair its ability to perform its commitments under the New Advisory
Agreement.

    The Manager is registered under the Investment Advisers Act of 1940. The
following table sets forth the name, title and principal occupation of each
director and executive officer of the Manager.

  (as such term is defined in Item 22 of Rule 14a-101 of the Securities Exchange Act of 1934, as amended) of the Manager.


    On November 1, 1998, the Fund's portfolio manager, John A. Frabotta, a
Director of the Fund, purchased an additional 13.33% of the Manager's capital
stock to bring his ownership of the Manager to 33 1/3%. The shares were sold
for $20,000 pursuant to a promissory note payable on December 31, 2002,
bearing interest at 6% per annum.

    The Fund did not effect any transactions through affiliated brokerage
firms during the fiscal year ended October 31, 1998.

   
    If adopted, the New Advisory Agreement will be materially the same as the
existing advisory agreement, except that Section 4 of the Advisory Agreement
will read in its entirety as follows:
    

      "ADVISORY FEE
          For the services and facilities to be provided by the Manager as set
      forth in paragraph 2 hereof, the Fund will pay to the Manager as full
      compensation therefor a fee at an annual rate of 0.70% of the Fund's net
      assets up to and including $200 million and (b) 0.65% of the excess of
      such managed assets over $200,000,000. For purposes hereof, net assets
      shall mean (a) the average weekly value of the total assets of the Fund,
      minus (b)(i) accrued liabilities of the fund (other than the principal
      amount of the Fund's "senior securities representing indebtedness" (as
      defined in the 1940 Act), not to exceed $75 million, and not including
      the aggregate liquidation preference of any preferred stock or other
      senior securities issued in lieu thereof (the "Preferred Stock")) and
      (ii) accumulated and unpaid dividends on the Preferred Stock. The fee to
      the Manager will be computed weekly and will be paid to the Manager
      monthly as soon as practicable following the end of each month.

          In the case of the commencement or termination of this Agreement
      during any month, the fee with respect to such month shall be adjusted
      proportionately."

                                  PROPOSAL 3

         RATIFICATION OF SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS

    The Board of Directors has selected the firm of Arthur Andersen LLP as
independent public accountants for the Fund for the fiscal year ending October
31, 1999. In accordance with the 1940 Act, the employment of such accountants
is conditioned upon the right of a majority of the outstanding voting
securities as defined above to terminate such employment. Stockholders are
being asked to ratify the selection of Arthur Andersen LLP to perform audit
services for the Fund.

    Arthur Andersen LLP has acted as independent public accountants for the
Fund since inception. The services provided by Arthur Andersen LLP consist of
(1) examination and audit of the Fund's semi-annual and annual financial
statements, (2) assistance and consultation in connection with Securities and
Exchange Commission filings and (3) review of tax matters on behalf of the
Fund.

    A representative of Arthur Andersen LLP is not expected to be represented
at the Annual Meeting but a representative of that firm will be available by
telephone to respond to appropriate questions.

REQUIRED VOTE
    Approval of the foregoing proposal requires the affirmative vote of the
holders of a majority of the Common Stock present and voting at the meeting.
Abstentions will not be counted as votes cast and will have no effect on the
result of the vote, although abstentions will count towards the presence of a
quorum.

    The Board of Directors, including those Directors who are not interested
persons of the Fund, recommends a vote FOR ratification of the selection of
Arthur Andersen LLP as independent public accountants of the Fund for the
fiscal year ending October 31, 1999.

                                ANNUAL REPORT

   
    All stockholders of record as of December 29, 1998, have been furnished or
are concurrently herewith being furnished with, a copy of the Fund's Annual
Report for the fiscal year ended October 31, 1998, which contains certified
financial statements of the Fund for the fiscal year ended October 31, 1998.
THE FUND WILL FURNISH, WITHOUT CHARGE, A COPY OF THE ANNUAL REPORT AND THE
FUND'S SEMI-ANNUAL REPORT FOR THE SIX MONTHS ENDED APRIL 30, 1998 TO A
SHAREHOLDER UPON REQUEST.
    

                   OTHER MATTERS TO COME BEFORE THE MEETING

    The Directors do not intend to present any other business at the Annual
Meeting nor are they aware that any stockholder intends to do so. If, however,
any other matters are properly brought before the Annual Meeting, the persons
named in the accompanying proxy will vote thereon in accordance with their
judgment.

                            STOCKHOLDER PROPOSALS

   
    Any proposals of stockholders that are intended to be presented at the
Fund's 2000 Annual Meeting of Stockholders must be received at the Fund's
principal executive offices no later than August 31, 1999 and must comply with
all other legal requirements in order to be included in the Fund's proxy
statement and form of proxy for that meeting.
    

    On May 21, 1998 the Securities and Exchange Commission adopted an
amendment to Rule 14a-4, as promulgated under the Securities and Exchange Act
of 1934, as amended. The amendment to Rule 14a-4 (c) (1) governs the Fund's
use of its discretionary proxy voting authority with respect to a stockholder
proposal which is not addressed in the Fund's proxy statement. The new
amendment provides that if a proponent of a proposal fails to notify the Fund
at least 45 days prior to the month and day of mailing of the prior year's
proxy statement, then the Fund will be allowed to use its discretionary voting
authority when the proposal is raised at the meeting, without any discussion
of the matter in the proxy statement.

   
    With respect to the Fund's 2000 Annual Meeting of Stockholders, if the
Fund is not provided notice of a stockholder proposal, which the stockholder
has not previously sought to include in the Fund's proxy statement by November
22, 1999, the Fund will be allowed to use its voting authority as outlined
above.
