PROXY STATEMENT
SPECIAL MEETING OF STOCKHOLDERS
DECEMBER 17, 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
Special Meeting of Stockholders (the "Special Meeting") to be held at the
offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., One Financial
Center, Boston, Massachusetts 02111, on December 17, 1999 at 10:00 a.m., and at
any and all adjournments thereof, for the purposes set forth in the accompanying
Notice of Special Meeting dated November 15, 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 Special Meeting and form
of proxy will be first sent to stockholders on or about November 15, 1999. The
Board of Directors has fixed the close of business on November 5, 1999 as the
record date for the determination of stockholders entitled to notice of and to
vote at the Special Meeting. As of the record date, 26,649,192 shares of the
Fund's Common Stock, $.01 par value per share (the "Common Stock"), were issued
and outstanding. As far as is known to the Fund, as of November 5, 1999, no
person or entity was the beneficial owner of shares of Common Stock representing
more than five percent of the Fund's outstanding shares of Common Stock.

If the accompanying form of proxy is properly executed and returned in time
to be voted at the Special 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 approval of a new investment
advisory agreement (the "New Advisory Agreement") between the Fund and Highland
Capital Management, L.P. ("Highland Capital") to take effect upon the closing of
an acquisition of certain assets of Prospect Street Investment Management Co.,
Inc. ("Prospect Management") by Highland Capital (the "Transaction"); and (2)
FOR the election of the nominees named herein as Directors of the Fund to hold
office together with four continuing Directors (none of whom are affiliates of
Prospect Management or Highland Capital). The Board of Directors does not know
of any matter to be considered at the Special Meeting other than the matters
referred to above. A stockholder may revoke his or her proxy prior to its use by
appearing at the Special 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 Special Meeting. In the event a quorum is
not present at the Special Meeting or in the event a quorum is present at the
Special 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 Special Meeting to permit further solicitation of proxies. Any such
adjournment will require the affirmative vote of a majority of those shares
present at the Special Meeting in person or by proxy. As described under
"Proposal 1 -- Approval of a New Advisory Agreement Which Will Take Effect Upon
the Closing of the Prospect Management Assets" and "Proposal 2 -- Election of
Directors," each Proposal is contingent upon the approval of the other.
Accordingly, no stockholder vote may be taken on only one of the two proposals
in this Proxy Statement prior to such adjournment.

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 1 and thus will have the effect
of a vote against such Proposal.

In addition to solicitation of proxies by mail, officers of the Fund and
officers and regular employees of Prospect Management, affiliates of Prospect
Management or other representatives of the Fund (none of whom will receive
additional compensation therefor) may also solicit proxies by telephone,
telegraph, mail or in person. The Fund is retaining Corporate Investor
Communications, a proxy solicitation firm to assist in the solicitation of
proxies. The costs of retaining such firm will be approximately $20,000, and
will depend upon the amount and type of services rendered. The first $150,000 of
costs of this proxy solicitation and other stockholder meeting-related expenses,
including the engagement of a proxy solicitation firm, incurred in connection
with preparing this Proxy Statement and its enclosures will be paid by Highland
Capital and any amount in excess of $150,000 will be paid by Prospect
Management. However, Prospect Management will reimburse Highland Capital for the
first $60,000 of such proxy solicitation expenses if the Fund's stockholders do
not approve the New Advisory Agreement. None of the costs and expenses
associated with the transactions described in this proxy statement (such as the
costs of special meetings of Directors) will be borne by the Fund. They will be
paid by Prospect Management or Highland Capital.

PROPOSAL 1

APPROVAL OF
A NEW ADVISORY AGREEMENT
WHICH WILL TAKE EFFECT UPON THE CLOSING
OF THE ACQUISITION OF THE PROSPECT MANAGEMENT ASSETS

SUMMARY OF THE TRANSACTION

On October 4, 1999, Highland Capital and Prospect Management entered into a
definitive agreement (the "Agreement") whereby Highland Capital will acquire
certain assets, including goodwill, of Prospect Management at a purchase price
equal to 5% of the value of the total assets of the Fund on the closing date of
the transaction (the "Transaction"). The purchase price is payable in cash.

There are a number of conditions precedent to the closing of the
Transaction. Such conditions include, among other things, that the existing
credit facility entered into among the Fund and Bank Boston, N.A., Commerzbank
AG, New York Branch, and Bank Boston, N.A., as Agent shall continue after the
Closing or that the Fund shall enter into a replacement credit facility in form
and substance satisfactory to Highland Capital. In addition, pursuant to Section
15 of the 1940 Act and the terms of the existing advisory agreement, the
existing investment advisory agreement automatically terminates upon its
assignment. Section 15(a) of the 1940 Act prohibits any person from serving as
an investment advisor to a registered investment company except pursuant to a
written contract that has been approved by the stockholders. Therefore in order
for Highland Capital to provide investment advisory services to the Fund after
the closing of the Transaction, the stockholders of the Fund must approve the
New Advisory Agreement. The closing of the Transaction is scheduled for January
21, 2000.

The Transaction also contemplates that Prospect Management and Highland
Capital and other persons will use their best efforts to comply with the
requirements of Section 15(f) of the 1940 Act after the closing. Section 15(f)
provides, in pertinent part, that Prospect Management may receive any amount or
benefit in connection with a sale of securities of, or a sale of any other
interest in, Prospect Management which results in an assignment of an investment
advisory contract if (1) for a period of three years after such event, at least
75% of the members of the board of directors of the Fund are not "interested
persons" (as defined in the 1940 Act) of Highland Capital or Prospect
Management; and (2) for a two-year period no "unfair burden" is imposed on the
Fund as a result of the Transaction.

The New Advisory Agreement, if approved by the Fund's stockholders, will
commence upon and subject to the closing of the Transaction. It will remain in
effect for an initial two-year term and will continue in effect thereafter for
successive periods if and so long as such continuance is specifically approved
annually by (a) the Board of Directors or (b) a majority vote (as defined under
the 1940 Act) of the Fund's stockholders, provided that in either event, the
continuance also is approved by a majority of the directors who are not
"interested persons" by vote cast in person at a meeting called for the purpose
of voting on such approval.

If the conditions for the proposed Transaction are not met and the
Transaction is not completed, the existing investment advisory agreement with
Prospect Management will remain in effect until February 28, 2000. The current
advisory agreement, dated March 1, 1994, was last approved by the Directors on
December 14, 1998 and by the stockholders on March 1, 1994. On December 14,
1998, the non-interested Directors of the Fund and, in addition, the full Board
of Directors approved a proposal, subject to stockholder approval, that would
have increased the advisory fee payable to Prospect Management. Although a
majority of the votes were cast in favor of the proposal at the Annual Meeting
of Stockholders of the Fund held on March 12, 1999, such proposal failed to win
the requisite 1940 Act supermajority vote necessary for approval.

During the fiscal year ended October 31, 1998 and the eleven months ended
September 30, 1999, the Fund paid $1,582,842 and $1,365,334, respectively, in
advisory fees to Prospect Management. The Fund did not effect any transactions
through affiliated brokerage firms during the fiscal year ended October 31, 1998
or thereafter.

After careful consideration, the Board of Directors of the Fund, including
all of the "non-interested" Directors (as defined under the 1940 Act)
(hereinafter "Independent Directors") unanimously recommends that stockholders
vote "FOR" the New Advisory Agreement between the Fund and Highland Capital to
replace the current advisory agreement between the Fund and Prospect Management
upon consummation of the Transaction. See "Evaluation by the Board" below.

BENEFITS TO STOCKHOLDERS
The Independent Directors have identified the following benefits which the
stockholders are anticipated to realize as a result of the Transaction:

1. In engaging Highland Capital, the Fund is believed to be contracting with
a larger organization having a greater depth of personnel with the
potential of strengthening the investment advisory services available to
the Fund.

2. Highland Capital has committed not to seek any increase in investment
advisory fees for two years after the closing (i.e., during the two-year
period of the New Advisory Agreement).

3. Highland Capital has advised the Independent Directors that it intends to
seek to manage the Fund in a manner such that the Fund's total expenses
(exclusive of interest, taxes, brokerage expenses and extraordinary
items, such as litigation expenses and expenses of new securities
offerings) as a percentage of net assets would not exceed, in any
material respect, the Fund's average total expenses similarly calculated
over the last two years. No assurance can be given that Highland Capital
will be able to achieve such objective.

Tower, 13455 Noel Road LB #45, Dallas, Texas 75240. Highland Capital has advised

THE NEW ADVISORY AGREEMENT

The Fund's current advisory agreement and the New Advisory Agreement are
identical, except for the parties, the termination date and a provision
requiring Highland Capital to advise the Fund of any changes to its general
partners. Accordingly, if the New Advisory Agreement is approved, Highland
Capital will be retained, for a two-year period at the existing fee schedule, to
manage the investments of the Fund and to provide such investment research,
advice and supervision, in conformity with the Fund's investment objectives and
policies, as may be necessary for the operation of the Fund. Under the New
Advisory Agreement, the Fund will pay Highland Capital a monthly advisory fee
which is equal to $0.65% (on an annual basis) of the average weekly value of the
net assets of the Fund up to and including $175,000,000 of such net assets,
0.55% on the next $50,000,000 of such net assets and 0.50% of the excess of such
net assets over $225,000,000. Net assets is defined as the total assets of the
Fund less (i) accrued liabilities of the Fund (excluding the principal amount of
the Fund's "senior securities representing indebtedness" as defined in the 1940
Act, not to exceed $50 million, and excluding the liquidation preference of any
outstanding shares of preferred stock or other senior securities) and (ii)
accumulated and unpaid dividends on preferred stock, if any.

Under the New Advisory Agreement, the Fund would bear all costs of its
operation other than those to be incurred by Highland Capital. In particular,
the Fund will pay 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 stockholder 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 investment advisor or any of its affiliates,
and any extraordinary expenses. Highland Capital will reimburse the Fund for any
expenses (excluding brokerage commissions, interest, taxes and extraordinary
items, such as 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 the New Advisory Agreement,
Highland Capital will provide the Fund with office space, facilities and
business equipment and provides the services of executive and clerical personnel
for administering certain of the affairs of the Fund. Highland Capital will
compensate Directors of the Fund if such persons are employed by Highland
Capital or its affiliates.

Pursuant to the New Advisory Agreement, the services of Highland Capital are
not exclusive and it may provide similar services to other investment companies
and other clients, so long as its services under the New Advisory Agreement are
not impaired.

The New Advisory Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, Highland Capital would not be liable to the Fund or any
of the Fund's stockholders for any act or omission by Highland Capital in the
supervision or management of its respective investment activities or for any
loss sustained by the Fund or the Fund's stockholders, and that the Fund will
indemnify Highland Capital subject to the requirements of the 1940 Act.

The New Advisory Agreement may be terminated at any time by the Fund or
Highland Capital, without the payment of any penalty, upon the vote of a
majority of the Fund's Board or a majority of the outstanding voting securities
of the Fund or by Highland Capital, on no less than 30 days' or more than 60
days' written notice by either party to the other.

A COPY OF THE FORM OF THE NEW ADVISORY AGREEMENT IS ANNEXED HERETO AS
EXHIBIT A AND IS INCORPORATED HEREIN BY REFERENCE.

In connection with the engagement of Highland Capital pursuant to the New
Advisory Agreement, the Independent Directors have nominated six additional
Directors for election by the stockholders (See Proposal No. 2), of which four
will be "non-interested" (as defined under the 1940 Act), and two, Messrs.
Dondero and Okada, are principals of Highland Capital. The four current "non-
interested" Independent Directors (John S. Albanese, C. William Carey, Harlan D.
Platt and Christopher E. Roshier) will remain as Directors. The Independent
Directors invited Highland Capital to provide the names of qualified individuals
as Board members. The additional "non-interested" nominees were selected from a
list of potential nominees submitted by Highland Capital for consideration and
evaluation by the Fund's current Independent Directors. The three Directors of
the Fund who are affiliated with Prospect Management will resign upon the
closing of the Transaction.

The Independent Directors, following consultation with representatives of
Highland Capital, and in light of the election of six new Directors at this
Special Meeting, also determined to amend the By-laws of the Fund to set the
date of the next annual meeting on or before August 31, 2000. Such change is
contingent upon stockholder approval of the New Advisory Agreement and the
closing of the Transaction. Accordingly, upon the occurrence of such events, the
next annual meeting of stockholders is expected to be held in July or August of
the year 2000. It is anticipated that subsequent annual meetings will be held in
March, commencing in March 2001.

In addition, Messrs. John S. Albanese and Christopher E. Roshier do not plan
to stand for re-election as Directors at the next annual meeting and their
vacancies are not anticipated to be filled by successor nominees. Messrs.
Albanese and Roshier have stated their intention to resign their directorships
on or before the later of July 1, 2000 or after the second regular quarterly
Board of Directors' meeting held following the closing of the Transaction at
which the Board considers Highland Capital's management of the Fund. At the
request of the current Independent Directors, Messrs. Albanese and Roshier have
agreed to continue for a period of six months thereafter, if they wish, as paid
advisory members to the Board (for fees at the same rate as are payable to
Independent Directors) to continue to assist the Board during this transitional
period with Highland Capital, as the new advisor.

EVALUATION BY THE BOARD

The Independent Directors met seven times over the course of more than two
months to determine whether or not to approve the New Advisory Agreement and
whether to recommend approval of the New Advisory Agreement to the entire Board
and to the stockholders of the Fund. In addition, there were several informal
meetings of certain Independent Directors relating to this matter. The
Independent Directors reviewed various materials, including the (i) due
diligence report prepared by Shields & Co., special independent financial
advisor to the Independent Directors, (ii) memoranda and other materials
provided by Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., special counsel
to the Independent Directors, (iii) reports produced by Highland Capital and
(iv) supplemental due diligence materials provided by Shields & Co. In addition,
the Independent Directors interviewed the principals of Highland Capital, both
during site visits made to Highland Capital's headquarters in Dallas, Texas and
during formal presentations made by the principals of Highland Capital to the
Independent Directors.

The progression of the events leading up to the determination to approve the
New Advisory Agreement are, briefly, as follows.

At their July 30, 1999 meeting, the Independent Directors met to discuss the
proposed Transaction (which had been brought to their attention by Prospect
Management) and the prospect of engaging Highland Capital to replace Prospect
Management as the Fund's new investment adviser. Senior officers of Highland
Capital and Prospect Management were present to answer questions from the
Independent Directors. The Independent Directors reviewed materials furnished by
Highland Capital, including information regarding Highland Capital and its
affiliates and their respective personnel, operations and financial condition.
The Independent Directors met with Highland Capital's principals, Messrs.
Dondero and Okada and Mr. Joseph Dougherty. The principals of Highland Capital
discussed Highland Capital's philosophy of management, performance expectations
and methods of operation insofar as they related to the Fund and indicated their
belief that, as a consequence of the Transaction, the ability to provide
investment advisory services to the Fund would not be adversely affected and
would likely be enhanced by the greater resources of Highland Capital. The
Independent Directors formally engaged an independent financial adviser, Shields
& Co., to assist them in their due diligence and evaluation of Highland Capital.
They also engaged special counsel to represent them in connection with their
evaluation of the New Advisory Agreement and related matters.

At a meeting held on August 12, 1999, the Independent Directors met and
discussed the results of Shields & Co.'s preliminary on-site due diligence
investigation of Highland Capital conducted at Highland Capital's headquarters
in Dallas, Texas. The Independent Directors reviewed a draft due diligence
report from Shields & Co. and made inquiries of its principal, Thomas Shields,
including inquiries into Highland Capital's investment strategy, historical
performance, future plans for the Fund, financial solvency, management expertise
and fee structure. The Independent Directors requested more comparative
performance data, including comparisons of Highland Capital against Prospect
Management and other industry indices.

At a meeting held on August 19, 1999, the issue of Board composition after
the Transaction was discussed, including the requirement of the 1940 Act that
75% of the Directors be "non-interested" members. The Independent Directors
heard presentations from special counsel. In addition, the Independent Directors
were provided supplemental due diligence materials by Shields & Co.

At a meeting held on August 26, 1999, Shields & Co. provided the Independent
Directors with an updated due diligence report and other supplemental materials
and advised the Independent Directors of additional comparative performance
data. There was further discussion about the post- Transaction composition of
the Board. The Independent Directors considered Highland Capital's suggestion to
add four additional non-interested members to the Board after the Transaction
and arrived at a consensus that the quality of the candidates was more important
than the number of the candidates.

At their meeting on September 2, 1999, Messrs. C. William Carey and John S.
Albanese, two of the Independent Directors, discussed their favorable
impressions of Highland Capital's operations and management formed during a site
visit they had made at Highland Capital's offices in Dallas, Texas. A discussion
then ensued about the quality of independent directors to be added to the Board
after the Transaction, resulting in the consensus that the Independent Directors
would interview as many qualified candidates as were suggested without strict
regard to the number of directors.

At a meeting held on September 10, 1999, the Independent Directors further
discussed Messrs. Carey and Albanese's onsite review of Highland Capital's
operations and their discussions with the principals of Highland Capital
regarding the 1940 Act obligations of the non-interested members of the Board.
At the September 10th meeting a discussion ensued regarding the possibility that
two of the existing Independent Directors might resign after a transition period
of approximately six months, but remain available to serve as observers for a
period of six additional months.

At their September 28, 1999 meeting, a further presentation to the
Independent Directors and Shields & Co. was made by representatives of Highland
Capital regarding recent investment performance, after which the Independent
Directors had the opportunity to direct questions to the principals of Highland
Capital. The Independent Directors, and thereafter the full Board of Directors,
considered and approved the proposed form of New Advisory Agreement, subject to
the execution and delivery of the Asset Purchase Agreement between Highland
Capital and Prospect Management and subject to approval by stockholders of the
Fund as required by the 1940 Act. The Board also elected C. William Carey as
interim Chairman of the Board of Directors.

On October 8 and November 12, 1999, the Independent Directors completed the
interview and nominating process and nominated six new Directors.

On the basis of the information made available to them and the results of
research carried out on their behalf, the Independent Directors have concluded
that Highland Capital is well qualified to serve as the Fund's investment
advisor by virtue of its depth of management and experience and the depth of
resources of its organization.

The Board of Directors, including all of the non-interested Directors,
recommends approval by the stockholders of the New Advisory Agreement. In making
this recommendation, the Directors carefully evaluated the experience of
Highland Capital's key personnel in institutional investing, and the quality of
services Highland Capital is expected to provide to the Fund; and have given
careful consideration to various factors deemed to be relevant to the Fund,
including, but not limited to: (1) the history, reputation, qualification and
background of Highland Capital, as well as the qualifications of its personnel
and its financial condition; (2) the investment performance of Highland Capital
since its commencement of operations, particularly with respect to its
investment record in managing "high yield" subordinated debt securities in
leveraged portfolios; (3) the nature and quality of the services expected to be
rendered to the Fund by Highland Capital; (4) that the compensation payable to
Highland Capital by the Fund under the New Advisory Agreement will be at the
same rate as the compensation now payable to Prospect Management under the
existing advisory agreement; (5) the advisory fees and expense ratios of
comparable leveraged high-yield closed-end funds; (6) that Highland Capital
intends to manage the Fund in such a manner that the expenses to be incurred
under the New Advisory Agreement would generally not be greater than those that
would otherwise be incurred under the current advisory agreement; and (7) that
the essential economic terms of the current advisory agreement (with Prospect
Management) will be unchanged for two years from the closing date of the
Transaction under the New Advisory Agreement.

Highland Capital has advised the Board of Directors that it expects that
there will be no reduction in the scope and quality of advisory services
provided to the Fund as a result of the Transaction. Based upon information
furnished by Highland Capital, the Board of Directors is not aware of any
financial condition of Highland Capital which is reasonably likely to impair its
ability to perform its commitments under the New Advisory Agreement.
Accordingly, although there can be no assurance thereof, the Board of Directors
believes that the Fund should receive investment advisory services under the New
Advisory Agreement at least equal to those it currently receives under the
current advisory agreement, at the same fee levels.

ACCORDINGLY, AFTER CONSIDERATION OF THE ABOVE, AND SUCH OTHER FACTORS AND
INFORMATION AS IT DEEMED RELEVANT, THE BOARD, INCLUDING ALL OF THE BOARD MEMBERS
WHO ARE NOT "INTERESTED PERSONS" (AS SUCH TERM IS DEFINED BY THE 1940 ACT),
UNANIMOUSLY APPROVED THE NEW ADVISORY AGREEMENT AND VOTED TO RECOMMEND ITS
APPROVAL TO THE FUND'S STOCKHOLDERS.

REQUIRED VOTE

Under the 1940 Act, approval of the New Advisory Agreement (this Proposal
No. 1) will require a vote of a majority of the outstanding voting securities of
the Fund, which means the lesser of either (a) the vote of 67% or more of the
shares 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. UNDER
APPLICABLE MARYLAND LAW, IN DETERMINING WHETHER THIS PROPOSAL NO. 1 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 PROPOSAL.

PROPOSAL 2

ELECTION OF DIRECTORS

The stockholders of the Fund are being asked to elect the following six
nominees as additional Directors of the Fund, to serve as such until the next
annual meeting of the Fund's stockholders and until their successors shall have
been duly elected and qualified. (See the discussion under "Proposal 1 Approval
of a New Advisory Agreement Which Will Take Effect Upon the Closing of the
Prospect Management Assets" with respect to the nomination of the new
Directors). Subject to shareholder approval of and upon effectiveness of the New
Advisory Agreement and the closing of the Transaction, the Board of Directors
has fixed the number of Directors of the Fund at ten pursuant to the Bylaws and
the Articles of Amendment and Restatement of the Fund. If the New Advisory
Agreement is not approved, the current Board of Directors of the Fund
(consisting of seven members) will continue to serve until the next annual

Frabotta, Joseph G. Cote, John S. Albanese, Harlan D. Platt, C. William Carey
and Christopher E. Roshier. If the New Advisory Agreement is approved and the

G. Cote will resign their positions on the Board. Two of the Fund's four current
Independent Directors, Messrs. Albanese and Roshier intend to resign their
Directorships effective the later of July 1, 2000 or immediately following the
second regular quarterly Board meeting following the closing of the Transaction
at which the Board considers Highland Capital's management 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

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

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 Special Meeting. Pursuant to the Articles of Incorporation,
holders of Common Stock have 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 By-laws of the Fund, the Independent Directors determined to
submit six nominees for election by the stockholders. Under the 1940 Act, the
holders of the Common Stock are, therefore, entitled to elect these nominees as
Directors.

The Fund will furnish, without charge, a copy of the Fund's Annual Report
for the fiscal year ended October 31, 1998 and the Fund's Semi-Annual Report for

any other matters are properly brought before the Special Meeting, the persons
named in the accompanying proxy will vote thereon in accordance with their
judgment.

EXHIBIT A
ADVISORY AGREEMENT
------------------------------

ADVISORY AGREEMENT made as of [ ], by and between Highland Capital
Management, L.P., a Delaware limited partnership (the "Manager"), and Prospect
Street High Income Portfolio Inc., a Maryland corporation having its principal
place of business in Boston, Massachusetts (the "Fund").

WHEREAS, the Fund is engaged in business as a closed-end management
investment company and is registered as such under the Investment Company Act of
1940, as amended (the "1940 Act"); and

WHEREAS the Manager is engaged principally in the business of rendering
investment management services and is registered as an investment adviser under
the Investment Advisers Act of 1940, as amended;

NOW, THEREFORE, WITNESSETH: That it is hereby agreed between the parties
hereto as follows:

1. APPOINTMENT OF MANAGER.

The Fund hereby appoints the Manager to act as manager and investment
adviser to the Fund for the period and on the terms herein set forth. The
Manager accepts such appointment and agrees to render the services herein set
forth, for the compensation herein provided.

2. DUTIES OF MANAGER.

The Manager, at its own expense, shall furnish the following services and
facilities to the Fund:

(a) Investment Program. The Manager shall (i) furnish continuously an
investment program for the Fund, (ii) determine (subject to the overall
supervision and review of the Board of Directors of the Fund) what
investments shall be purchased, held, sold or exchanged by the Fund and what
portion, if any, of the assets of the Fund shall be held uninvested, and
(iii) make changes in the investments of the Fund. The Manager also shall
manage, supervise and conduct the other affairs and business of the Fund and
matters incidental thereto, subject always to the control of the Board of
Directors of the Fund, and to the provisions of the Articles of Amendment
and Restatement (the "Articles of Incorporation") and By-laws of the Fund,
the Prospectuses of the Fund, and the 1940 Act, in each case as from time to
time amended and in effect. Subject to the foregoing, the Manager shall have
the authority to engage one or more sub-advisers in connection with the
management of the Fund, which sub-advisers may be affiliates of the Manager.

(b) Office Space and Facilities. The Manager shall furnish the Fund
office space in the offices of the Manager, or in such other place or places
as may be agreed upon from time to time, and all necessary office
facilities, simple business equipment, supplies, utilities and telephone
service for managing the affairs and investments of the Fund.

(i) the preparation of all reports now or hereafter required by
federal or other laws; and

(ii) the preparation of prospectuses, registration statements and
amendments thereto that may be required by federal or other
laws or by the rules or regulations of any duly authorized
commission or administrative body.

(d) Services of Personnel. The Manager shall provide all necessary
executive and administrative personnel for managing the affairs of the Fund,
including personnel to perform clerical, bookkeeping, accounting and other
office functions. These services are exclusive of the bookkeeping and
accounting services of any dividend disbursing agent, transfer agent,
registrar or custodian. The Manager shall compensate all personnel, officers
and directors of the Fund if such persons are also employees of the Manager
or its affiliates.

In providing services of the type contemplated by the foregoing
paragraphs (c) and (d), the Manager shall be entitled to retain the services
of one or more accounting, consulting or similar firms, provided that the
Manager shall pay all fees and expenses of any firms so retained and shall
remain responsible for the provision of the services described herein.

(e) Fidelity Bond. The Manager shall arrange for providing and
maintaining a bond issued by a reputable insurance company authorized to do
business in the place where the bond is issued against larceny and
embezzlement covering each officer and employee of the Fund who may singly
or jointly with others have access to funds or securities of the Fund, with
direct or indirect authority to draw upon such funds or to direct generally
the disposition of such funds. The bond shall be in such reasonable amount
as a majority of the directors who are not "interested persons" of the Fund,
as defined in the 1940 Act, shall determine, with due consideration given to
the aggregate assets of the Fund to which any such officer or employee may
have access. The premium for the bond shall be payable by the Fund in
accordance with paragraph 3(m).

(f) Portfolio Transactions. The Manager shall place all orders for the
purchase and sale of portfolio securities for the account of the Fund with
brokers or dealers selected by the Manager, although the Fund will pay the
actual brokerage commissions on portfolio transactions in accordance with
paragraph 3(d).

In placing portfolio transactions for the Fund, it is recognized that the
Manager will give primary consideration to securing the most favorable price and
efficient execution. Consistent with this policy, the Manager may consider the
financial responsibility, research and investment information and other services
provided by brokers or dealers who may effect or be a party to any such
transaction or other transactions to which other clients of the Manager may be a
party. It is understood that neither the Fund nor the Manager has adopted a
formula for allocation of the Fund's investment transaction business. It is also
understood that it is desirable for the Fund that the Manager have access to
supplemental investment and market research and security and economic analysis
provided by brokers who may execute brokerage transactions at a higher cost to
the Fund than would otherwise result when allocating brokerage transactions to
other brokers on the basis of seeking the most favorable price and efficient
execution. Therefore, the Manager is authorized to place orders for the purchase
and sale of securities for the Fund with such brokers, subject to review by the
Fund's Board of Directors from time to time with respect to the extent and
continuation of this practice. It is understood that the services provided by
such brokers may be useful or beneficial to the Manager in connection with its
services to other clients.

On occasions when the Manager deems the purchase or sale of a security to be
in the best interest of the Fund as well as other clients, the Manager, to the
extent permitted by applicable laws and regulations, may, but shall be under no
obligation to, aggregate the securities to be so sold or purchased in order to
obtain the most favorable price or lower brokerage commissions and efficient
execution. In such event, allocation of the securities so purchased or sold, as
well as the expenses incurred in the transaction will be made by the Manager in
the manner it considers to be the most equitable and consistent with its
fiduciary obligations to the Fund and to such other clients.

3. ALLOCATION OF EXPENSE.

Except for the services and facilities to be provided by the Manager as set
forth in paragraph 2 above, the Fund assumes and shall pay all expenses for all
other Fund operations and activities and shall reimburse the Manager for any
such expenses incurred by the Manager. The expenses to be borne by the Fund
shall include, without limitation:

(a) all expenses of organizing the Fund;

dividend disbursing agent, shareholder servicing agent, custodian or

provided to the Fund (other than those utilized by the Manager in providing
the services described in Section 2), (ii) any agent engaged for the
purposes of conducting auctions with respect to the Fund's taxable auction
rate preferred stock, if any shall be issued, (iii) any institution serving
as trustee with respect to the Fund's Senior Extendible Notes, and (iv) fees

outstanding securities of the Fund;

Fund, including general ledger accounting;

similar coverage with respect to securities of the Fund;

specifically identified expenses.

4. 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 0.65% of the Fund's net assets up to and
including $175 million, 0.55% on the next $50 million, and 0.50% of the excess
over $225 million (which for purposes hereof, 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 $50
million, and not including the aggregate liquidation preference of the Fund's
outstanding preferred stock (the "Preferred Stock"), if any, 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 commencement or termination of this Agreement during any
month, the fee with respect to such month shall be adjusted proportionately.

5. EXPENSE LIMITATION.

The Manager agrees that if the total expenses of the Fund (exclusive of
interest, taxes, brokerage expenses and extraordinary items such as litigation
expenses) for any fiscal year of the Fund exceed the lowest expense limitation
imposed by any jurisdiction to which the Fund is then subject, if any, the
Manager will pay or reimburse the Fund for that excess up to the amount of its
advisory fees payable with respect to the Fund during that fiscal year. The
amount of the monthly advisory fee payable by the Fund under paragraph 4 hereof
shall be reduced to the extent that the monthly expenses of the Fund, on an
annualized basis, would exceed the foregoing limitation. At the end of each
fiscal year of the Fund, if the aggregate annual expenses chargeable to the Fund
for that year exceed the foregoing limitation based upon the average of the
monthly average net asset values of the Fund for the year, the Manager will
promptly reimburse the Fund for the amount of such excess to the extent not
already reimbursed by reduction of the monthly advisory fee, but if such
expenses are within the foregoing limitation, any excess amount previously
withheld from the monthly advisory fee during that fiscal year will be promptly
paid over to the Manager.

In the event that this Agreement (i) is terminated as of a date other than

voting securities (as defined in the 1940 Act) of the Fund, voting as a
single class.
