AGREEMENT


                  THIS AGREEMENT made and entered into effective as of May 15,
1996 (this Agreement, as the same may hereafter be amended from time to time,
hereinafter referred to as this "Agreement"), by and between PanAmSat
Corporation, a Delaware corporation (hereinafter referred to as "COMPANY"), and
Patrick J. Costello (hereinafter referred to as "EXECUTIVE").

                              W I T N E S S E T H:

                   WHEREAS, EXECUTIVE is currently serving COMPANY as its Chief
Financial Officer; and

                  WHEREAS, the BOARD OF DIRECTORS of COMPANY believes that it is
in the best interests of COMPANY to enter into this Agreement with EXECUTIVE,
and EXECUTIVE desires to enter into this Agreement with COMPANY.

                  NOW, THEREFORE, in consideration of the foregoing and the
promises, covenants and agreements hereinafter set forth, COMPANY and EXECUTIVE
hereby agree as follows:


A.       Term

                  1. Term. The Term of this Agreement shall be the period
commencing on May 1, 1996 and ending on the third anniversary of such date;
provided, however, that commencing on the date two years after May 1, 1996, and
on each annual anniversary of such date (such date and each annual anniversary
thereof shall be hereinafter referred to as the "Renewal Date"), unless
previously terminated, the Term shall be automatically extended so as to
terminate two years after such Renewal Date, unless at least 60 days prior to
the Renewal Date the Company shall give notice to the Executive that the Term
shall not be so extended; provided, further that obligations and benefits
arising hereunder prior to the expiration of the Term shall continue until fully
satisfied.

                  2. Employment Duties. If a Material Change (as hereinafter
defined) should occur during the Term, absent the occurrence of an event that
gives the COMPANY the right to terminate the EXECUTIVE for Cause (as defined
below), COMPANY shall be obligated to continue to employ EXECUTIVE for the
remainder of the Term in the same executive capacity in which EXECUTIVE was
employed immediately prior to such Material Change with substantially the same
duties and responsibilities that EXECUTIVE had immediately prior to such
Material Change; provided, however, that, if COMPANY should cease to be a public
company after a Material Change, the fact that EXECUTIVE may thereupon cease to
have certain duties and responsibilities that were attributable solely to the
status of COMPANY as a public company shall not be deemed to be a breach of this
Section A.2.

                  Termination for "Cause" shall mean a termination based on (a)
the commission by EXECUTIVE of any felony or crime involving moral turpitude; or
(b) the engagement of EXECUTIVE in any business or activity that is directly
competitive with any business or activity of COMPANY and which, in the opinion
of the Board of Directors of COMPANY, is prejudicial or adverse to the best
interests of COMPANY; provided, however, that, after the occurrence of a
Material Change, EXECUTIVE may be discharged for "Cause" only if COMPANY is able
to establish that the action for which he is being discharged under clause (a)
or (b) of this subsection is an action for which he would have been discharged
for "Cause" under COMPANY'S general employment policies and practices in effect
immediately prior to such Material Change.


B.     Material Change

                  1.       Definition.  A "Material Change" shall be deemed to 
have occurred for the purposes of this Agreement if any of the following events
should occur:

                            (i) The sale (in one or more transactions) of all 
                  or substantially all of the assets of COMPANY; or

                           (ii) The loss by the Holders (as defined below) of
                  the COMPANY's Class A Common Stock of the power to elect a
                  majority of the Board of Directors of COMPANY; or

                          (iii) A majority of the Board of Directors ceases to
                  consist of nominees of the Holders of COMPANY's Class A Common
                  Stock; or

                           (iv) A complete liquidation or dissolution of 
                  COMPANY;

provided, that the term "Holders" shall mean and include only the holders,
beneficially or otherwise, of the Company's Class A Common Stock on the date
hereof, their lineal descendants, trusts for the benefit of any such holders and
corporations or other business entities of which all of the capital stock or
other ownership interest is held by such holders.

                  2. Termination Event. Provided that EXECUTIVE has not been
terminated for Cause, EXECUTIVE shall be entitled to a Termination Payment (as
hereinafter defined) and shall have the right to elect to terminate his services
with COMPANY after the occurrence of a Material Change, and (a) during the 30
day period following the one year anniversary of a Material Change, or (b) if
within two years following a Material Change:

                            (i)     COMPANY shall terminate the EXECUTIVE for 
                  any reason other than for Cause; or

                           (ii) COMPANY should fail to continue to employ
                  EXECUTIVE during the Term in the same executive capacity with
                  COMPANY in which EXECUTIVE was employed immediately prior to
                  such Material Change, with materially the same duties and
                  responsibilities with COMPANY that EXECUTIVE had immediately
                  prior to such Material Change, except, in the case where
                  COMPANY ceases to be a public company after such Material
                  Change, for those duties and responsibilities that were
                  attributable solely to the status of COMPANY as a public
                  company; provided, that the EXECUTIVE shall be required prior
                  to the effectiveness of a constructive termination pursuant to
                  this subsection (ii) to have given the COMPANY ten (10) days
                  notice and an opportunity to cure such failure. Without in any
                  way limiting the right of EXECUTIVE to elect to terminate his
                  services under this Section B.2(ii), it is understood that any
                  change in EXECUTIVE's job description (other than as described
                  in the exception to the first sentence of this clause (ii)),
                  offices, perquisites or place of employment by more than 35
                  miles (unless such move is from the Greenwich, Connecticut
                  offices of COMPANY to New York City), any reduction in the
                  number of officers or other employees or diminishment in the
                  overall management responsibility of officers and other
                  employees reporting directly to EXECUTIVE (other than as
                  described in the exception to the first sentence of this
                  clause (i)), any diminishment in the decision making authority
                  of EXECUTIVE, shall each be a change in his duties and
                  responsibilities that will give EXECUTIVE the right to elect
                  to terminate his services under this Section B.2(i); or

                          (iii) COMPANY should reduce or fail to pay or award to
                  EXECUTIVE when due any Base Salary, Bonus (as both such terms
                  are defined below) or other amount payable to EXECUTIVE or to
                  provide EXECUTIVE with any benefits to which EXECUTIVE is
                  entitled.

                  If EXECUTIVE should make any such election during the Term,
EXECUTIVE shall be entitled to a Termination Payment from COMPANY, which
Termination Payment shall be due and payable ten (10) days after EXECUTIVE gives
COMPANY written notice of such election. The term "Termination Payment" in
respect of any election by EXECUTIVE to terminate his services with COMPANY
during the two year period following the occurrence of a Material Change shall
mean an amount that is equal to 3 times the sum of (1) the Base Salary (as
defined below), plus (2) the Applicable Bonus (as defined below). The term "Base
Salary" shall mean the annual cash compensation to EXECUTIVE by COMPANY for
services payable at the time of the termination, or at the time of the Material
Change, whichever is greater and the term "Applicable Bonus" shall mean the
annual amount awarded or paid under any incentive or bonus plan or program of
COMPANY and any additional amounts (such aggregate amounts, the "Bonus") paid to
EXECUTIVE by COMPANY during the fiscal year ending immediately prior to the
fiscal year in which the Material Change occurred, or the Bonus scheduled to be
paid to EXECUTIVE during the fiscal year in which the Material Change occurs,
prorated to the date of termination, whichever is greater. The Termination
Payment is intended to constitute liquidated damages to compensate EXECUTIVE for
amounts EXECUTIVE could have earned in respect of future services and shall not
be subject to reduction based upon any compensation that EXECUTIVE may receive
(or could have received) in respect of any services EXECUTIVE performs (or could
have performed) after EXECUTIVE terminates his services with COMPANY. The
Termination Payment shall be in addition to and not in lieu of any rights or
claims that EXECUTIVE may have in respect of past services and any rights or
claims, past or future, that EXECUTIVE may have under Section B.2 or Section C
hereof, and EXECUTIVE shall retain all of his rights and claims in respect of
past services and all of his rights and claims, past or future, under Section C
hereof.

                  3.       Base Salary; Bonuses.

                  (a) Following the occurrence of a Material Change and during
the Term, Executive shall receive an annual base salary ("Annual Base Salary"),
which shall be paid at a monthly rate at least equal to twelve times the highest
monthly base salary paid or payable (including any base salary which has been
earned but deferred) to Executive by Company during the period between the
initial public disclosure of the potential Material Change and the month in
which the Material Change occurs. Thereafter, the Annual Base Salary shall be
reviewed at intervals no less frequent than customary for Executive prior to the
Material Change. Any increase in Annual Base Salary shall not serve to limit or
reduce any other obligation to the Executive under this Agreement. Annual Base
Salary shall not be reduced after any such increase during the Employment Period
and the term Annual Base Salary as utilized in this Agreement shall refer to
Annual Base Salary as so increased.

                  (b) Following the occurrence of a Material Change, COMPANY
shall be obligated to award EXECUTIVE an unconditional bonus for each fiscal
year for so long as EXECUTIVE is employed by COMPANY (including the fiscal year
in which the Material Change occurs) in an amount not less than the higher of
the annual bonus awarded to EXECUTIVE by COMPANY for the fiscal year preceding
the fiscal year in which the Material Change occurs and the annual bonus for the
EXECUTIVE for the fiscal year in which the Material Change occurs, which
unconditional bonus must be awarded and paid not later than the last day of each
year during which EXECUTIVE is employed by COMPANY; provided that such bonus
shall be prorated for any year in which EXECUTIVE has given notice to COMPANY of
his election to terminate his services upon the occurrence of a Termination
Event as set forth in Section B.2 hereof.

                  4. Excise Tax. In the event that, in connection with a
Material Change or at any time following a Material Change, the Termination
Payment or any other amounts payable to EXECUTIVE, his designated beneficiary or
his dependents under this Agreement or under any plan, program or policy of
COMPANY, or any benefits provided to EXECUTIVE or his dependents under this
Agreement or under any option or other plan, program or policy of COMPANY,
should become subject to the excise tax imposed under Section 4999 of the Code
or any similar tax or assessment (collectively, "Excise Taxes"), COMPANY shall
pay to EXECUTIVE, his designated beneficiary or his dependents, as the case may
be, on demand, the amount (the "Excise Tax Reimbursement Amount") necessary
fully to reimburse EXECUTIVE, his designated beneficiary or his dependents for
(i) all Excise Taxes that may be imposed on EXECUTIVE, his designated
beneficiary or his dependents and (ii) any and all income and other taxes,
including additional Excise Taxes, that may be imposed on EXECUTIVE, his
designated beneficiary or his dependents in respect of any of the amounts to be
paid to EXECUTIVE, his designated beneficiary or his dependents under clause (i)
above or under this clause (ii). The determination of the Excise Tax
Reimbursement Amount shall initially be made by the accounting firm that is
serving as COMPANY's independent public accountants immediately prior to the
Material Change, or, if such accounting firm is no longer in existence, by its
successor. All costs and expenses of such accounting firm in connection with
making such determination shall be paid by COMPANY. If it is subsequently
determined (as a result of an assessment of additional Excise Taxes by the
Internal Revenue Service or otherwise) that the Excise Tax Reimbursement Amount
is not sufficient fully to reimburse EXECUTIVE, his designated beneficiary or
his dependents as contemplated above, COMPANY shall pay to EXECUTIVE, his
designated beneficiary or his dependents, as the case may be, on demand, the
amount (the "Additional Excise Tax Reimbursement Amount") necessary fully to
reimburse EXECUTIVE, his designated beneficiary or his dependents for (I) any
and all additional Excise Taxes, income taxes and other taxes that may be
imposed on EXECUTIVE, his designated beneficiary or his dependents, (II) any and
all interest, fines and penalties that may be imposed on EXECUTIVE, his
designated beneficiary or his dependents in connection with any such additional
Excise Taxes, income taxes or other taxes, and (III) any and all income and
other taxes, including additional Excise Taxes, that may be imposed on
EXECUTIVE, his designated beneficiary or his dependents in respect of any of the
amounts to be paid to EXECUTIVE, his designated beneficiary or his dependents
under clause (I) or (II) above or under this clause (III). If it is subsequently
determined that the EXECUTIVE has received a sum greater than necessary to pay
any such Excise Taxes, the EXECUTIVE shall promptly return such overage to
COMPANY. The purpose of this Section B.4 is to place EXECUTIVE, his designated
beneficiary and his dependents in the same position on an after-tax basis that
each of them would have been in if the Termination Payment and all other amounts
payable to EXECUTIVE, his designated beneficiary or his dependents under this
Agreement or under any plan, program or policy of COMPANY, and all benefits
provided to EXECUTIVE or his dependents under this Agreement or under any plan,
program or policy of COMPANY, had not been subject to any Excise Taxes.

                  5. Payment for Past Services. The termination of EXECUTIVE's
employment with COMPANY for any reason, including "Cause", shall not diminish or
otherwise affect in any way the obligations of COMPANY with respect to the
payment of any Base Salary, Bonuses or other compensation (whether payable
currently or deferred) in respect of past services, and EXECUTIVE shall retain
all of his rights and claims in respect of past services and all of his rights
and claims, past and future, under Section C hereof, except to the extent
expressly provided otherwise in Section C hereof, as the case may be.


C.       Employee Benefits

                  From and after the occurrence of a termination event pursuant
to Section B.2 (other than for "Cause") and until the earlier of the expiration
of the second year following such event or the securing of similar benefits from
a subsequent employer, EXECUTIVE and his dependents shall be entitled to
participate in all employee welfare benefit plans (as that term is defined in
Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended)
and to receive or participate in all other benefit arrangements, policies or
practices to which and in which active executive employees of COMPANY and/or
their dependents are or shall become entitled to receive or participate in at
any time during the Term; provided, however, that, if a Material Change should
occur, the benefits required to be provided to EXECUTIVE and his dependents
under the provisions of this Section C shall be no less than the employee
benefits EXECUTIVE and his dependents would have received under the provisions
of the benefit arrangements, policies or practices of COMPANY in effect
immediately prior to such Material Change, all at no increased cost or expense
to EXECUTIVE and his dependents.


D.       Notice

                  Any notice given under this Agreement shall be sufficient if
in writing and if sent by registered or certified mail, postage prepaid,
addressed, in the case of COMPANY, to its then principal office to the attention
of its Board of Directors; in the case of EXECUTIVE, to his last known address;
in the case of the designated beneficiary, to his, her or their last known
address; or, in the case of EXECUTIVE's dependents, to their last known address.


E.       Binding Effect

                  This Agreement shall inure to the benefit of and be binding
upon and enforceable against (i) COMPANY and its successors and assigns
(including, without limitation, the surviving corporation in any merger or
consolidation with COMPANY), (ii) EXECUTIVE and his heirs, executors,
administrators and legal representatives, (iii) with respect to Sections B, D,
E, F, G, H, I, J and K, the designated beneficiary and his or her heirs,
executors, administrators and legal representatives, and (iv) with respect to
Sections B, C, D, E, F, G, H, I, J and K, EXECUTIVE's dependents and their
respective heirs, executors, administrators and legal representatives. In
addition, without in any way limiting the foregoing, following a Material
Change, any person or entity (or group of persons and/or entities) that acquires
(in a single transaction or a series of related transactions) any businesses or
assets of COMPANY representing 25% or more of COMPANY's sales, operating profits
or operating assets shall be deemed to be a successor of COMPANY for the
purposes of this Agreement and shall be liable for the payment of all amounts
payable by COMPANY under this Agreement and for the performance of all
obligations of COMPANY under this Agreement.


F.       Governing Law

                  All questions relating to the validity, construction,
interpretation, performance and administration of this Agreement shall be
governed by and construed in accordance with the laws of the State of New York
covering contracts made and to be performed in that State. Following a Material
Change, this Agreement is to be interpreted and construed in the manner most
favorable to EXECUTIVE, his designated beneficiary and his dependents (and their
respective heirs, executors, administrators and personal representatives).


G.       No Trust, Etc.

                  Neither this Agreement nor any action taken pursuant to the
provisions of this Agreement shall create or be construed to create a trust or
fiduciary relationship of any kind between COMPANY and EXECUTIVE, his designated
beneficiary or his dependents or any other person. To the extent that EXECUTIVE,
his designated beneficiary or his dependents or any other person acquires a
right to receive any payments or other benefits from COMPANY under this
Agreement, such right shall be no greater than the right of any unsecured
general creditor of COMPANY, and any and all amounts credited to make any
payment or provide any other benefit to EXECUTIVE, his designated beneficiary or
his dependents or any other person shall continue for all purposes to be a part
of the general funds of COMPANY, and no person other than COMPANY shall have any
interest in any such funds. The right of EXECUTIVE, his designated beneficiary
or his dependents or any other person to receive payments or other benefits
under this Agreement may not be pledged or encumbered and cannot be assigned or
transferred except by will or by the laws of descent and distribution.


H.       Attorneys' Fees and Other Costs and Expenses

                  EXECUTIVE, his designated beneficiary and his dependents (and
their respective heirs, executors, administrators and personal representatives)
shall each be entitled to recover from COMPANY (and shall be reimbursed by
COMPANY when incurred and upon demand) all attorneys' fees and other costs and
expenses, if any, that may be incurred in connection with enforcing or defending
the rights of EXECUTIVE, his designated beneficiary or his dependents under this
Agreement following a Material Change regardless of the outcome of any
litigation or other proceeding relating to such enforcement or defense.
EXECUTIVE, his designated beneficiary and his dependents (and their respective
heirs, executors, administrators and personal representatives) also shall be
entitled to recover from COMPANY interest on the Termination Payment and any
other amounts that may be payable to EXECUTIVE, his designated beneficiary or
his dependents under this Agreement (including, without limitation, amounts
required to be reimbursed under the first sentence of this Section, any Excise
Tax Reimbursement Amount or Additional Excise Tax Reimbursement Amount under
Section B.4 hereof that are not paid when due following a Material Change, at an
annual rate equal to 4% over the corporate base rate as announced from time to
time by Citibank, N.A. or its successor (changing as and when such announced
corporate base rate changes), compounded monthly, from the date due until paid.
Payments received by EXECUTIVE, his designated beneficiary or his dependents (or
any of their respective heirs, executors, administrators and personal
representatives) shall be credited first against accrued interest until all
accrued interest is paid in full before any such payment is credited against the
Termination Payment or any other amounts that may be payable to EXECUTIVE, his
designated beneficiary or his dependents under this Agreement.


I.       SUBMISSION TO JURISDICTION

                  EACH PARTY AGREES THAT IT SHALL BRING ANY ACTION OR PROCEEDING
IN RESPECT OF ANY CLAIM ARISING OUT OF OR IN RESPECT OF THIS AGREEMENT WHETHER
IN TORT OR CONTRACT OR AT LAW OR IN EQUITY, EXCLUSIVELY IN THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK OR THE SUPREME COURT OF THE
STATE OF NEW YORK FOR THE COUNTY OF NEW YORK (THE "CHOSEN COURTS") AND (I)
IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE CHOSEN COURTS, (II)
WAIVES ANY OBJECTION TO LAYING OF VENUE IN ANY SUCH ACTION OR PROCEEDING IN THE
CHOSEN COURTS, AND (III) WAIVES ANY OBJECTION THAT THE CHOSEN COURTS ARE AN
INCONVENIENT FORUM OR DO NOT HAVE JURISDICTION OVER ANY PARTY HERETO.


J.       Counterparts

                  This Agreement may be executed in one or more counterparts,
each of which shall be deemed an original, and all of which shall constitute one
and the same Agreement.


K.       Severability

                  The provisions of this Agreement shall be deemed severable and
the invalidity or unenforceability of any provision shall not affect the
validity or enforceability of the other provisions hereof. If any provision of
this Agreement is invalid or unenforceable, (a) a suitable and equitable
provision shall be substituted therefor in order to carry out, so far as may be
valid and enforceable, the intent and purpose of such invalid or unenforceable
provision and (b) the remainder of this Agreement shall not be affected by such
invalidity or unenforceability, nor shall such invalidity or unenforceability
affect the validity or enforceability of such provision, or the application
thereof, in any other jurisdiction.


L.       No Competing Employment

                  For 18 months following the occurrence of a termination event
pursuant to Section B.2, provided that Executive has received the payments due
to him hereunder, Executive shall not, unless he has received the prior written
consent of the Company, become employed by or otherwise render personal services
to any corporation, firm, or other entity which directly competes with the
Company.






IN WITNESS WHEREOF, COMPANY and EXECUTIVE have executed this Agreement as of the
day and year first above written.
