                           REVOLVING CREDIT AGREEMENT

      This REVOLVING CREDIT AGREEMENT (the "Agreement") dated as of June 1,
1996, among Hudson General Corporation ("HGC"), a Delaware corporation having
its principal place of business at 111 Great Neck Road, Great Neck, New York
11022, The First National Bank of Boston, 100 Federal Street, Boston,
Massachusetts 02110, in its individual capacity ("FNB"), European American Bank,
1 EAB Plaza, Uniondale, New York 11555 ("EAB"), The Chase Manhattan Bank, N.A.,
135 Pinelawn Street, Melville, New York 11747 ("Chase") and such other banks as
may become parties hereto from time to time in accordance with the provisions
hereof (each singly, a "Bank" and collectively, the "Banks"), and The First
National Bank of Boston as agent for the Banks (the "Agent"). Capitalized terms
used in this Agreement shall have the meanings set forth in Exhibit A attached
hereto or in the sections of this Agreement referred to in Exhibit A. All
accounting terms shall, unless otherwise specified, be given the meanings
ascribed to them by generally accepted accounting principles.

      Section 1.  THE REVOLVING CREDIT FACILITY; LETTERS OF CREDIT.

      Section 1.1. Commitment to Lend. Subject to the terms and conditions of
this Agreement, including, without limitation, the conditions precedent set
forth in Paragraph 4B hereof, and upon prior notice given to the Agent by HGC,
as provided in Paragraph 1.3, each Bank severally agrees from time to time to
make loans to HGC (individually, a "Revolving Credit Loan" and collectively, the
"Revolving Credit Loans") in an aggregate principal amount requested by HGC from
time to time between the Effective Date and the Revolving Credit Loan Maturity
Date, up to a maximum aggregate amount outstanding (after giving effect to all
amounts requested) at any one time equal to such Bank's Commitment Percentage of
the Aggregate Loan Limit, provided that the sum of the aggregate outstanding and
unpaid principal amount of all Revolving Credit Loans (after giving effect to
all amounts requested) plus the aggregate Maximum Drawing Amount of all
outstanding Letters of Credit shall at no time exceed the Aggregate Loan Limit.
Promptly upon receipt of a request for Revolving Credit Loans by HGC, the Agent
will notify the Banks thereof, and each Bank will make the proceeds of its
Revolving Credit Loan available in United States dollars in immediately
available funds on the requested date at the head office of the Agent, 100
Federal Street, Boston, Massachusetts 02110. The Revolving Credit Loans shall be
made pro rata in accordance with each Bank's Commitment Percentage. The Banks'
obligations hereunder shall be several and not joint, and except as otherwise
specifically provided in this Agreement, no Bank's obligation to lend shall be
affected by any other Bank's failure to make any Revolving Credit Loan.

      Section 1.2. Notes to Evidence Revolving Credit Loans. The Revolving
Credit Loans will be evidenced by separate promissory notes of HGC in the form
of Exhibit B attached hereto (each a "Revolving Credit Note") appropriately
completed, executed and delivered by HGC to the Banks on the Effective Date.
Prior to any transfer of a
   8
                                      -2-


Revolving Credit Note, each Bank shall record thereon any appropriate notations
evidencing each Revolving Credit Loan and payment of principal made thereunder.
The outstanding amount of the Revolving Credit Loans recorded on each Bank's
Revolving Credit Note shall be prima facie evidence of the principal amount
thereof owing and unpaid to such Bank, but the failure to record, or any error
in so recording, any such amount shall not limit or otherwise affect the
obligations of HGC hereunder or under any Revolving Credit Note to make payments
of principal or interest on any Revolving Credit Note when due.

      Section 1.3. Election of Form of Revolving Credit Loan. (a) As long as no
Default has occurred and is continuing and no condition which would, with either
or both the giving of notice or the lapse of time, result in a Default has
occurred and is continuing, the Banks agree from time to time between the
Effective Date and the Revolving Credit Loan Maturity Date to make Revolving
Credit Loans as either Base Rate Loans or LIBO Rate Loans, to permit conversion
of Revolving Credit Loans that are Base Rate Loans or LIBO Rate Loans to
Revolving Credit Loans of the other Type subject where applicable to Paragraph
2.6 hereof or to continue a Revolving Credit Loan as a LIBO Rate Loan for the
same Interest Period or a different Interest Period, provided that no Interest
Period shall extend beyond the Revolving Credit Loan Maturity Date. Each Base
Rate Loan made on any single occasion shall be in the minimum aggregate
principal amount of $100,000 or an integral multiple thereof. Each LIBO Rate
Loan, or a conversion thereto or a continuation thereof, made on any single
occasion shall be in the minimum aggregate principal amount of $1,000,000 or if
higher, in integral multiples of $250,000.

      (b) Each Revolving Credit Loan shall be made, each conversion of a
Revolving Credit Loan from one Type to another Type and each continuation of a
Revolving Credit Loan as a LIBO Rate Loan for the same Interest Period or a
different Interest Period shall occur, upon notice (confirmed in writing, if
oral) given to the Agent by HGC no later than:

            (i)   if a Base Rate Loan, the same Business Day prior to 10:00
      a.m. (Boston time); or

            (ii) if a LIBO Rate Loan, 11:00 a.m. (Boston time), three Business
      Days prior to commencement of the applicable Interest Period.

In its notice, HGC shall specify the amount of such Revolving Credit Loan and,
if a LIBO Rate Loan, the applicable Interest Period. Each notice with regard to
borrowing or a conversion to or a continuation of a LIBO Rate Loan shall be
irrevocable and binding upon HGC. Any LIBO Rate Loan shall automatically convert
to a Base Rate Loan at the end of the applicable Interest Period unless HGC in
accordance with the procedures set forth in this Paragraph 1.3 shall give the
requisite notice to continue such LIBO Rate Loan for the same or a different
Interest Period.

      Section 1.4. Aggregate Loan Limit. (a) The "Aggregate Loan Limit" shall
initially be $6,000,000 and shall be irrevocably reduced (i) by such amounts by
which HGC may from time to time, upon three Business Days' prior written notice
to the Banks, elect to
   9
                                      -3-


reduce the same (in integral multiples of $100,000 or in the full remaining
amount of the Aggregate Loan Limit), (ii) from time to time in accordance with
the parenthetical of Paragraph 5.11(f)(ii) hereof and (iii) from time to time in
accordance with Paragraph 5.14(a)(iv) hereof. On the effective date of any
reduction, there shall become due and payable and HGC will pay or cause to be
paid the amount, if any, by which the sum of the aggregate outstanding and
unpaid principal amount of all Revolving Credit Loans plus the aggregate Maximum
Drawing Amount of all outstanding Letters of Credit, exceeds the reduced
Aggregate Loan Limit on the effective date of such reduction. Each repayment of
Revolving Credit Loans shall be made ratably among the Banks in accordance with
their Commitment Percentages and each reduction in the Aggregate Loan Limit
shall be made ratably among the Banks in accordance with their Commitment
Percentages.

            (b) Upon the written request by HGC to the Banks received by the
Banks no later than 90 days prior to the Revolving Credit Loan Maturity Date and
the written consent of all of the Banks (such consent to be given at the sole
discretion of each Bank), the Initial Revolving Period may be extended for
successive annual periods and the Revolving Credit Loan Maturity Date shall be
reset accordingly. In the event that any revolving period is extended, HGC shall
(A) (i) execute and deliver to each of the Banks restated Revolving Credit Notes
reflecting the extended Revolving Credit Loan Maturity Date and each of the
Banks shall return to HGC the existing Revolving Credit Notes, or (ii) execute
and deliver to each of the Banks a letter authorizing such Bank to change the
Revolving Credit Loan Maturity Date set forth in such Bank's existing Revolving
Credit Note to the extended Revolving Credit Loan Maturity Date and (B) provide
each Bank with such evidence of existence and due authorization of such extended
period of borrowing, including an opinion of counsel to HGC as to the due
execution, delivery, validity and binding effect of such Revolving Credit Note
as restated or extended, as such Bank reasonably may request. In no event shall
any revolving period be extended unless at the time of such extension each of
the conditions precedent to the making of a Revolving Credit Loan set forth in
Paragraph 4B of this Agreement has been satisfied.

      Section 1.5. Repayment of Revolving Credit Loans. The sum of the aggregate
outstanding and unpaid principal amounts of all Revolving Credit Loans plus the
aggregate Maximum Drawing Amounts of all outstanding Letters of Credit shall at
no time exceed the Aggregate Loan Limit, and HGC will make or cause to be made
such payments on account of principal as are necessary to comply with the
foregoing limitation, with accrued interest to the date of prepayment on the
principal amount prepaid. Payment in full of all obligations on or with respect
to the Revolving Credit Notes shall be due on the Revolving Credit Loan Maturity
Date and HGC promises to pay in full on the Revolving Credit Loan Maturity Date
all Obligations on or with respect to the Revolving Credit Notes. HGC may at any
time upon three Business Days' prior written notice to the Agent make or cause
to be made full or partial prepayment of the Revolving Credit Loans in an
integral multiple of $100,000, with accrued interest to the date of such
prepayment on the principal amount prepaid, for pro-rata application to the
Revolving Credit Loans outstanding under the Revolving Credit Notes, with
adjustments to the extent practicable to equalize any prior prepayment not
exactly in proportion, without premium or penalty, provided that
   10
                                      -4-


LIBO Rate Loans may be prepaid only on the last day of the Interest Period
applicable thereto (or otherwise with the consequences set forth in Paragraph
2.6). Subject to the terms and conditions of this Agreement, HGC may reborrow
any amount so prepaid.

      Section 1.6. Revolving Credit Loans Commitment Fee. HGC agrees to pay to
the Agent, for the account of the Banks in accordance with their respective
Commitment Percentages, quarterly in arrears on the last day of each calendar
quarter commencing June 30, 1996, a commitment fee, computed from the Effective
Date at the rate of 1/2 of 1% per annum on the aggregate daily unused portion of
the Aggregate Loan Limit.

      Section 1.7. Letters of Credit. Subject to the terms and conditions set
forth in this Agreement, upon written request of HGC to the Letter of Credit
Bank in accordance with this Paragraph 1.7, the Letter of Credit Bank shall
issue, with pro rata participation by all of the Banks, at any time between the
Effective Date and the Revolving Credit Loan Maturity Date and subject to the
satisfaction of the conditions precedent set forth in Paragraph 4B hereof,
Letters of Credit in such form as HGC and the Letter of Credit Bank may agree
for the account of HGC, provided that at no time shall the aggregate Maximum
Drawing Amounts of all outstanding Letters of Credit exceed $2,000,000, and
provided further that at no time shall the sum of the aggregate outstanding and
unpaid principal balance of all outstanding Revolving Credit Loans plus the
aggregate Maximum Drawing Amounts of all outstanding Letters of Credit exceed
the Aggregate Loan Limit. Letters of Credit shall be issued only for the
following purposes: (i) to support HGC's insurance policies, and (ii) for HGC's
business purposes in the ordinary course of HGC's business. Each request for
issuance of a Letter of Credit shall be in writing and shall be received by the
Letter of Credit Bank at least three Business Days prior to the proposed date of
issuance. The expiry dates, amounts and beneficiaries of the Letters of Credit
will be as designated by HGC and reasonably approved by the Letter of Credit
Bank. The Letter of Credit Bank promptly shall notify the Banks of the amounts
of all Letters of Credit issued hereunder and of any extension, reduction or
termination thereof, and the Letter of Credit Bank shall send the Banks copies
of all Letters of Credit issued hereunder as soon as reasonably practicable
after the issuance thereof. HGC may request, and the Letter of Credit Bank, upon
terms and conditions approved by HGC, shall issue, with pro rata participation
by all of the Banks, substitute Letters of Credit for the Letters of Credit to
reflect reductions in the amount of HGC's obligations supported by such Letters
of Credit. Each Letter of Credit issued by the Letter of Credit Bank hereunder
shall identify: (i) the dates of issuance and expiry of such Letter of Credit,
(ii) the amount of such Letter of Credit (which shall be a sum certain), (iii)
the beneficiary and account party of such Letter of Credit, and (iv) the drafts
and other documents necessary to be presented to the Letter of Credit Bank upon
drawing thereunder. No Letter of Credit issued hereunder shall expire after the
first anniversary of its date of issuance (provided that, at HGC's request,
Letters of Credit may contain provisions for extension or renewal, which such
extension or renewal shall be at the Banks' option, for additional terms not in
excess of one year), and in no event shall any Letter of Credit issued hereunder
expire after the Revolving Credit Loan Maturity Date. HGC agrees to execute and
deliver to the Letter of Credit Bank such further documents and instruments in
connection with any Letter of Credit issued hereunder as the Letter of Credit
Bank in accordance with its customary practices may request.

                                      -5-


      Section 1.8. Drawings. HGC hereby absolutely and unconditionally promises
to pay the Letter of Credit Bank as soon as possible but in any event within one
Business Day after any drawing under a Letter of Credit, in immediately
available funds, the amount of such drawing under such Letter of Credit, plus
interest thereon from the date of such drawing until repaid in full at an annual
rate equal to the Base Rate in effect from time to time. If HGC so requests in
accordance with Paragraph 4B.1 and if each of the conditions precedent to the
making of a Revolving Credit Loan set forth in Paragraph 4B of this Agreement
has been satisfied on the Business Day following a drawing under a Letter of
Credit, the amount of such drawing, plus interest thereon, for which the Letter
of Credit Bank has not been reimbursed by HGC shall become a Revolving Credit
Loan made by the Banks to HGC on such day as provided in Paragraph 1.1 hereof
bearing interest at an annual rate equal to the Base Rate in effect from time to
time. The Letter of Credit Bank shall give written notice (which written notice
shall be by facsimile transmission or telex) to HGC and the Banks of the
occurrence and amount of each drawing under a Letter of Credit promptly upon the
occurrence thereof. Each Bank agrees that on the second Business Day after any
such drawing, such Bank will immediately make available to the Letter of Credit
Bank at its head office in Boston, Massachusetts, in Federal or other
immediately available funds, its ratable share of any such drawing, plus any
interest which shall have accrued thereon, provided that each Bank's obligation
shall be reduced by its pro rata share of any reimbursement by HGC in respect of
such drawing pursuant to this Paragraph 1.8. Paragraph 1.9 hereof shall govern
HGC's obligations with respect to drawings under Letters of Credit.

      Section 1.9. Letter of Credit Loan Obligations Absolute. (a) The
obligation of HGC to reimburse the Letter of Credit Bank as provided hereunder
in respect of drawings under Letters of Credit shall rank pari passu with the
obligation of HGC to repay the Revolving Credit Loans hereunder, and shall be
absolute and unconditional under any and all circumstances and shall be secured
pro rata with the other Obligations pursuant to the Security Documents. Without
limiting the generality of the foregoing, HGC's obligation to reimburse the
Letter of Credit Bank in respect of drawings under Letters of Credit shall not
be subject to any defense based on the non-application or misapplication by the
beneficiary of the proceeds of any such payment or the legality, validity,
regularity or enforceability of the Letters of Credit or any related document or
any dispute between or among HGC, the beneficiary of any Letter of Credit or any
financing institution or other party to which any Letter of Credit may be
transferred. The Letter of Credit Bank may accept or pay any draft presented to
it under any Letter of Credit regardless of when drawn or made and whether or
not negotiated, if such draft, accompanying certificate or documents and any
transmittal advice are presented or negotiated on or before the expiry date of
the Letter of Credit, or any renewal or extension thereof then in effect.
Furthermore, neither the Letter of Credit Bank nor any of its correspondents
shall be responsible, as to any document presented under a Letter of Credit
which appears to be regular on its face, and appears on its face to conform to
the terms of the Letter of Credit, for the validity or sufficiency of any
signature or endorsement, for delay in giving any notice or failure of any
instrument to bear adequate reference to the Letter of Credit, or for failure of
any person to note the amount of any draft on the reverse of the Letter of
Credit.

            (b) Any action, inaction or omission on the part of the Letter of
Credit Bank or any of its correspondents under or in connection with any Letter
of Credit or the related instruments, documents or property, if in good faith
and in conformity with such laws, regulations or customs as are applicable,
shall be binding upon HGC and shall not place the Letter of Credit Bank or any
of its correspondents under any liability to HGC, in the absence of (i) gross
negligence or willful misconduct by the Letter of Credit Bank or its
correspondents or (ii) the failure by the Letter of Credit Bank to pay under a
Letter of Credit after presentation of a draft and documents strictly complying
with such Letter of Credit. The Letter of Credit Bank's rights, powers,
privileges and immunities specified in or arising under this Agreement are in
addition to any heretofore or at any time hereafter otherwise created or
arising, whether by statute or rule of law or contract. All Letters of Credit
issued hereunder will, except to the extent otherwise expressly provided
hereunder, be governed by the Uniform Customs and Practice for Documentary
Credits (1993 Revision), International Chamber of Commerce, Publication No. 500,
and any subsequent revisions thereof.

      Section 1.10. Banks' Obligations in Respect of Letters of Credit. Each
Bank acknowledges that each Letter of Credit issued by the Letter of Credit Bank
pursuant to this Agreement is issued by the Letter of Credit Bank on behalf of
and with the pro rata participation of all of the Banks, agrees to make the
payments required by Paragraph 1.8 hereof and agrees to be responsible for its
pro rata share of all liabilities incurred by the Letter of Credit Bank in
respect of each Letter of Credit opened or extended by the Letter of Credit Bank
hereunder for the account of HGC. Each Bank agrees with the Letter of Credit
Bank and the other Banks that its obligation to make the payments required by
Paragraph 1.8 hereof shall not be affected in any way by any circumstances
(other than the gross negligence or willful misconduct of the Letter of Credit
Bank) occurring before or after the making of any payment by the Letter of
Credit Bank pursuant to any Letter of Credit, including, without limitation:

            (a) any modification or amendment of, or any consent, waiver,
      release or forbearance with respect to, any of the terms of this Agreement
      or any other instrument or document referred to herein;

            (b)  the existence of any Default; or

            (c)  any change of any kind whatsoever in the financial position
      or creditworthiness of HGC.

      Section 1.11. Letter of Credit Fee. HGC shall pay to the Letter of Credit
Bank for its own account a fee in respect of each Letter of Credit issued
pursuant to Paragraph 1.7 hereof calculated at the rate of 1/4% per annum on the
Maximum Drawing Amount of each such Letter of Credit, payable quarterly in
advance during the term of such Letter of Credit, commencing upon the date of
issuance thereof. HGC also shall pay to the Letter of Credit Bank for the
accounts of the Banks (including FNB) in accordance with their Commitment
Percentages a fee in respect of each such Letter of Credit calculated at the
rate of 1-3/8% per annum on the Maximum Drawing Amount thereof, payable
quarterly in advance during the term of such Letter of Credit, commencing
   13
                                      -7-


upon the date of issuance thereof (the foregoing fees are referred to
collectively as the "Letter of Credit Fee"). In addition (but without
duplication), HGC shall pay to the Letter of Credit Bank for its own account its
standard processing, negotiating, amendment and administrative fees, as
determined in accordance with the Letter of Credit Bank's customary fees and
charges for similar facilities.

      Section 2.   CERTAIN GENERAL PROVISIONS.

      Section 2.1. Agent's Fee. HGC shall pay to the Agent annually in advance,
for the Agent's own account, an Agent's fee in the amount of $7,500 on the
Effective Date and an Agent's fee of $5,000 on each anniversary of the Effective
Date during the term of this Agreement.

      Section 2.2. Facility Fee. HGC agrees to pay to the Agent for the pro rata
accounts of the Banks on the Effective Date a facility fee in the amount of
$18,750.

      Section 2.3. Interest. Except as otherwise provided in the last sentence
of this Paragraph 2.3, the Revolving Credit Notes shall bear interest on the
unpaid principal amount thereof not then due and payable, computed as follows:

            (a)   for Base Rate Loans, at a rate per annum equal to the Base
      Rate as in effect from time to time; and

            (b) with respect to LIBO Rate Loans, at a rate per annum equal to
      1-3/8% above the LIBO Rate determined for the applicable Interest Period;

provided that notwithstanding anything to the contrary contained in this
Agreement or in the Revolving Credit Notes, the Banks shall not charge nor shall
HGC be required to pay interest in an amount in excess of that permitted by
applicable law. All payments of interest on Base Rate Loans shall be made
quarterly in arrears on the last day of each calendar quarter commencing June
30, 1996, and on the date when any Base Rate Loan is paid in full. Interest on
each LIBO Rate Loan shall be payable (i) on the last day of each Interest Period
relating thereto, and (ii) if any Interest Period is longer than three months,
also on the last day of each three-month period following the commencement of
such Interest Period. Any change in the Base Rate shall result in an immediate
corresponding change in the rate of interest payable on Base Rate Loans. The
Agent shall promptly notify HGC of any change in the Base Rate. Overdue
principal of and, to the extent permitted by law, overdue interest on each
Revolving Credit Note shall bear interest at a rate which is two percentage
points (2%) per annum above the Base Rate in effect from time to time,
compounded monthly whether before or after judgment. All computations of
interest and commitment fees shall be made on the basis of the actual number of
days elapsed divided by 360.

      Section 2.4. Place and Mode of Payments. All payments due hereunder shall
be made, in immediately available funds in United States dollars, by HGC to the
Agent at its head office at 100 Federal Street, Boston, Massachusetts 02110.
Promptly upon receipt by the Agent of any payment, it shall wire, in immediately
available funds, to each Bank its applicable share (taking into account the
provisions of Paragraph 2.11
   14
                                      -8-


hereof) of such payment. Whenever a payment becomes due on a day which is not a
Business Day, the maturity thereof shall be extended to the next succeeding
Business Day, and interest and commitment fees shall accrue during such
extension. HGC hereby requests and authorizes the Agent to charge HGC's deposit
account with the Agent for all interest on the Revolving Credit Loans and all
fees payable hereunder on the dates when any such amounts are due.

      Section 2.5. Inability of Agent to Determine LIBO Rates; Illegality. (a)
If the Agent shall in good faith determine that it is unable to ascertain the
LIBO Rate prior to any Interest Period, the Agent shall promptly notify HGC of
such determination (which shall be conclusive and binding on HGC and the Banks).
In such event (i) any loan request with respect to a LIBO Rate Loan to which
such Interest Period would otherwise relate shall be deemed to be a request for
a Base Rate Loan (unless HGC withdraws its request therefor), (ii) each LIBO
Rate Loan will automatically, on the last day of the then current Interest
Period relating thereto, become a Base Rate Loan, and (iii) the obligations of
the Banks to make LIBO Rate Loans or convert Base Rate Loans to LIBO Rate Loans
shall be suspended until the Agent determines that the circumstances giving rise
to such suspension no longer exist, whereupon the Agent shall so notify HGC and
the Banks. Such determination shall be made by the Agent on the day preceding
the first day of the applicable Interest Period.

            (b) Notwithstanding any other provisions herein, if any present or
future law, regulation, treaty or directive or in the interpretation or
application thereof shall make it unlawful for any Bank to make or maintain LIBO
Rate Loans, such Bank shall forthwith give notice of such circumstances to HGC
and the other Banks and thereupon (i) the obligation of such Bank to make LIBO
Rate Loans or convert Base Rate Loans to LIBO Rate Loans shall forthwith be
suspended and such Bank shall have no obligation to make LIBO Rate Loans for
purposes of Paragraph 2.11 hereof but shall make Base Rate Loans in like amount
(HGC hereby agreeing to accept such Base Rate Loans), and (ii) such LIBO Rate
Loans, if any, shall be converted automatically to Base Rate Loans on the last
day of the then current Interest Period applicable to such LIBO Rate Loans or
within such earlier period as may be required by law. HGC hereby agrees promptly
to pay the Agent for the account of such Bank, upon demand by such Bank, any
additional amounts necessary to compensate such Bank for any costs incurred by
such Bank in making any conversion in accordance with this Paragraph 2.5,
including any interest or fees payable by such Bank to lenders of funds obtained
by it in order to make or maintain its LIBO Rate Loans hereunder.

      Section 2.6. Indemnification for Losses. Without prejudice to any of the
other provisions of this Agreement, HGC will, on demand by any Bank, at any time
and from time to time and as often as the occasion therefor may arise, indemnify
such Bank against any losses, costs or expenses which such Bank may at any time
and from time to time sustain or incur as a consequence of:

            (a) the failure by HGC to borrow any LIBO Rate Loan, convert any
      Base Rate Loan to a LIBO Rate Loan or continue any LIBO Rate Loan on the
      date of borrowing, conversion or continuation designated by HGC; or
   15
                                      -9-


            (b) the failure by HGC to pay, punctually on the due date thereof,
      any amount payable by HGC with respect to or on account of any LIBO Rate
      Loan; or

            (c) repayment or conversion by HGC of all or any portion of any LIBO
      Rate Loan prior to the last day of the applicable Interest Period, whether
      due to acceleration of the maturity of the Revolving Credit Loans or due
      to any other reason;

such losses, costs or expenses to include, without limitation:

                  (i) any costs incurred by such Bank in carrying funds which
            were to have been borrowed by HGC (net of any interest or other
            amounts received in any redeployment of such funds) or in carrying
            funds to cover the amount of any overdue principal of or overdue
            interest on any of the LIBO Rate Loans;

                  (ii) any interest payable by such Bank to lenders of the funds
            borrowed by such Bank in order to carry the funds referred to in the
            immediately preceding subclause (i) (net of any interest or other
            amounts received in any redeployment of such funds); and

                  (iii) any losses (excluding losses of anticipated profit)
            incurred by such Bank in liquidating or reemploying funds acquired
            from third parties to effect or maintain all or any part of any LIBO
            Rate Loan.

      Section 2.7. Payments to be Free of Deductions. (a) All payments by HGC
hereunder shall be made without setoff or counterclaim, and free and clear of
and without deduction for any taxes, levies, imposts, duties, charges, fees,
deductions, withholdings, compulsory loans, restrictions or conditions of any
nature now or hereafter imposed or levied by any jurisdiction or any political
subdivision thereof or taxing or other authority therein (excluding in the case
of the Agent and each Bank, net income and profit and franchise taxes imposed on
the Agent or such Bank by the jurisdiction under the laws of which the Agent or
such Bank is organized or any subdivision or taxing authority thereof or therein
or by the United States of America or any taxing authority thereof), unless HGC
is compelled by law to make such deduction or withholding. If any such
obligation is imposed upon HGC with respect to any amount payable by it
hereunder, it will pay to the Banks on the date on which such amount becomes due
and payable hereunder, such additional amount as shall be necessary to enable
the Banks to receive the same net amount which they would have received on such
due date had no such obligation been imposed upon HGC. If HGC shall be required
by law to make such deduction or withholding, it will deliver to the Banks tax
receipts or other appropriate evidence of payment.

            (b) Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the Effective Date, and from time to time
thereafter if requested in writing by HGC, shall provide HGC with two original
Internal Revenue Service forms 1001, 4224 or W-8 as appropriate, or any
successor or other form
   16
                                      -10-


prescribed by the Internal Revenue Service, certifying that such Bank is exempt
from or entitled to a reduced rate of United States withholding tax on payments
pursuant to this Agreement. If a Bank provides a form W-8 (or any successor or
related form) to the Agent and HGC pursuant to this Paragraph 2.7, such Bank
shall also provide a certificate stating that such Bank is not a "bank" within
the meaning of Section 881(c) (3) (A) of the Internal Revenue Code of 1986 and
shall promptly notify the Agent and HGC if such Bank determines that it is no
longer able to provide such certification. Upon the reasonable request of HGC or
the Agent, each Bank that has not provided the forms or other documents, as
provided above, on the basis of being a United States person shall submit to HGC
and the Agent a certificate to the effect that it is such a "United States
person" (as defined in Section 7701 (a) (30) of the Internal Revenue Code).

            (c) For any period with respect to which a Bank has failed to
provide HGC with the appropriate form described in Paragraph 2.7(b) (other than
if such failure is due to a change in law occurring subsequent to the date on
which such Bank became a party hereunder), such Bank shall not be entitled to
indemnification under this Agreement with respect to taxes imposed by the United
States.

      Section 2.8. Change in Circumstances; Additional Costs. Anything herein to
the contrary notwithstanding, if any present or future applicable law (which
expression, as used herein, includes statutes, rules and regulations thereunder
and interpretations thereof by any competent court or by any governmental or
other regulatory body or official charged with the administration or the
interpretation thereof, and requests, directives, instructions and notices at
any time or from time to time hereafter made upon or otherwise issued to any
Bank or the Agent by any central bank or other fiscal, monetary or other
authority, whether or not having the force of law) shall:

            (a) subject any Bank or the Agent to any tax, levy, impost, duty,
      charge, fee, deduction or withholding of any nature with respect to this
      Agreement, any Letters of Credit, such Bank's Commitment or the Revolving
      Credit Loans (other than taxes based upon or measured by the income or
      profits of such Bank or the Agent), or

            (b) materially change the basis of taxation of (except for changes
      in taxes on income or profits) payments to any Bank or the Agent of the
      principal of or the interest on any Revolving Credit Loans or any other
      amounts payable to any Bank or the Agent hereunder with respect to the
      Revolving Credit Loans, or

            (c) impose or increase or render applicable (other than to the
      extent specifically provided for elsewhere in this Agreement) any special
      deposit, reserve, assessment, liquidity, capital adequacy or other similar
      requirements, whether or not having the force of law, against assets held
      by, or deposits in or for the account of, or loans by, or letters of
      credit issued by, or commitments of a class of banks including an office
      of any Bank, or
   17
                                      -11-


            (d) impose on a class of banks including any Bank or the Agent any
      other conditions or requirements with respect to this Agreement, any
      Revolving Credit Note, any Letters of Credit, the Revolving Credit Loans,
      such Bank's Commitment, or any class of loans, letters of credit or
      commitments of which the Revolving Credit Loans, the Letters of Credit or
      such Bank's Commitment forms a part;

and the result of any of the foregoing is:

                  (i) to increase the cost to any Bank or the Agent of making,
            funding, issuing, renewing, extending or maintaining any of the
            Revolving Credit Loans or such Bank's Commitment or any Letter of
            Credit, or

                  (ii) to reduce the amount of principal, interest or other
            amount payable to any Bank or the Agent hereunder, on account of
            such Bank's Commitment, any Letter of Credit or any of the Revolving
            Credit Loans, or

                  (iii) to require any Bank or the Agent to make any payment or
            to forego any interest or other sum payable hereunder, the amount of
            which payment or foregone interest or other sum is calculated by
            reference to the gross amount of any sum receivable or deemed
            received by such Bank or the Agent from HGC hereunder,

then, and in each case, HGC will, promptly upon demand made by such Bank or (as
the case may be) the Agent, at any time and from time to time and as often as
the occasion therefor may arise, pay or cause to be paid to such Bank or the
Agent such additional amounts as will be sufficient to compensate such Bank or
the Agent for such additional cost, reduction, payment or foregone interest or
other sum.

      Section 2.9. Additional Amounts Payable on Account of Credit Facilities.
If any present or future law, governmental rule, regulation, policy, guideline
or directive (whether or not having the force of law) or the interpretation
thereof by any court or by any governmental or other regulatory body or official
charged with the administration or interpretation thereof affects the amount of
capital required to be maintained by any Bank or the Agent or any corporation
controlling such Bank or the Agent and such Bank or the Agent determines that
the amount of capital required to be maintained by it is increased by or based
upon the existence of such Banks' or the Agent's Commitment with respect to any
Revolving Credit Loans or Letters of Credit, in any case, other than any change
already reflected in the Reserve Rate then in effect, then such Bank or the
Agent shall notify HGC of such fact (the "Notice Date"), and, in the case of a
Bank, shall send a copy of such notice to the Agent. HGC and such Bank or (as
the case may be) the Agent shall thereafter attempt to negotiate an adjustment
to the compensation payable hereunder which will adequately compensate such Bank
or (as the case may be) the Agent in light of these circumstances. If HGC and
such Bank or (as the case may be) the Agent are unable to agree to such
adjustment within thirty days of the day on which HGC receives such notice, then
commencing on the 90th day
   18
                                      -12-


after the Notice Date, the fees and interest payable hereunder shall increase by
an amount which will, in such Bank's or (as the case may be) the Agent's
reasonable determination, provide adequate compensation.

      Section 2.10. Certificates. A certificate signed by an officer of any Bank
or the Agent, setting forth any additional amount required to be paid to such
Bank or the Agent under Paragraphs 2.6 through 2.9 hereof, and the computations
made by such Bank or the Agent to determine such additional amount, shall be
submitted by the Bank or the Agent to HGC (and, with respect to demands made by
a Bank, to the Agent) in connection with each such demand, and each such
certificate shall, save for manifest error, constitute prima facie evidence of
the additional amount due. A claim by any Bank or the Agent for all or any part
of any additional amount due may be made promptly before and/or after the end of
the Interest Period to which such claim relates or during which such claim has
arisen, and before and/or after any repayment to which such claim relates.

      Section 2.11. Delinquent Banks. Notwithstanding anything to the contrary
contained in this Agreement, any Bank that fails (i) to make available to the
Agent its pro rata share of any Revolving Credit Loan or any drawing under any
Letter of Credit or (ii) to comply with the provisions of Paragraph 8 with
respect to making dispositions and arrangements with the other Banks, where such
Bank's share of any payment received, whether by setoff or otherwise, is in
excess of its pro rata share of such payments due and payable to all of the
Banks, in each case as, when and to the full extent required by the provisions
of this Agreement, shall be deemed delinquent (a "Delinquent Bank") and shall be
deemed a Delinquent Bank until such time as such delinquency is satisfied. A
Delinquent Bank shall be deemed to have assigned any and all payments due to it
from HGC, whether on account of outstanding Revolving Credit Loans, interest,
fees or otherwise, to the remaining nondelinquent Banks for application to, and
reduction of, their respective pro rata shares of all outstanding Revolving
Credit Loans (it being understood that any such assignment shall not affect the
obligation of any Bank, including the Delinquent Bank, to make the percentage of
the Revolving Credit Loans or to participate in the issuance of Letters of
Credit requested by HGC hereunder equal to such Bank's Commitment Percentage).
The Delinquent Bank hereby authorizes the Agent to distribute such payments to
the nondelinquent Banks in proportion to their respective pro rata shares of all
outstanding Revolving Credit Loans. A Delinquent Bank shall be deemed to have
satisfied in full a delinquency when and if, as a result of application of the
assigned payments to all outstanding Revolving Credit Loans of the nondelinquent
Banks, the Banks' respective pro rata shares of all outstanding Revolving Credit
Loans have returned to those in effect immediately prior to such delinquency and
without giving effect to the nonpayment causing such delinquency.

      Section 3. REPRESENTATIONS AND WARRANTIES. HGC represents and warrants
that:

      Section 3.1. Organization and Qualification; Authority. (a) Each of HGC
and its Subsidiaries (i) is a corporation or, in the case of Hudson General LLC

conduct its business as now conducted and as presently contemplated, and (iii)
is duly qualified and in good standing as a foreign entity and is duly
authorized to do business in each jurisdiction where the nature of its

in which the failure to qualify has no material adverse effect on the business,
assets or financial condition of HGC and its Subsidiaries, taken as a whole, or
on HGC's ability to perform its obligations under the Loan Documents.

            (b) The execution, delivery and performance by HGC of this Agreement
and the other Loan Documents and the borrowings hereunder and the transactions
contemplated under this Agreement and the other Loan Documents (i) are within
the corporate authority of HGC, (ii) have been duly authorized by all necessary
corporate proceedings, (iii) will not contravene any provision of HGC's charter
documents or bylaws, or contravene any provision of, or result in the creation
of any mortgage, lien, pledge, charge, security interest or other encumbrance
upon any of the property of HGC (other than the Liens created under the Security
Documents) under, any other agreement, instrument or undertaking binding upon
HGC or any property of HGC, and (iv) do not conflict with or result in any
breach or contravention of any provision of law, statute, rule or regulation to
which HGC is subject or any judgment, order, writ, injunction, license or permit

            (c) Schedule 3.1 attached hereto is a complete and correct list of
all the presently existing Subsidiaries of HGC and the percentage of the capital
stock thereof owned by HGC or a Subsidiary of HGC, as such schedule may be
supplemented from time to time by written notice from HGC to the Banks. Except
for the Joint Ventures, none of HGC nor any Restricted Subsidiary of HGC is
engaged in any joint venture or partnership with any other entity.

      Section 3.2. Valid Obligation. Each of this Agreement and the other Loan
Documents has been duly executed and delivered by HGC, and each of this
Agreement and the other Loan Documents constitutes a valid and legally binding
obligation of HGC, enforceable against HGC in accordance with its terms, except
as the enforcement of remedies may be limited by bankruptcy, insolvency,
reorganization, moratorium or other laws relating to or affecting generally the
enforcement of creditors' rights.

      Section 3.3. Governmental Approvals. The execution, delivery and
performance of this Agreement and the other Loan Documents, the borrowings
hereunder and the transactions contemplated hereby and thereby do not require,
except as set forth in clauses (a) and (b) of Section 12 of the Pledge Agreement
and clauses (a) through (d) of Section 18 of the Security Agreement and except

its Subsidiaries, taken as a whole, any approval or consent of, or filing by HGC
with, any governmental or other agency or authority or any other party, or the
giving of notice to any governmental or other agency or authority or any other
party, or the recording or the delivery to other persons of an environmental

                                      -14-


      Section 3.4. Title to Properties; Absence of Liens. Except for liens
permitted by Paragraph 5.11 hereof, each of HGC and its Restricted Subsidiaries
has good and merchantable title to all of its properties, assets and rights of
every name and nature now purported to be owned by it, free from all defects,
liens, charges and encumbrances whatsoever.

      Section 3.5. Financial Statements. (a) HGC has previously furnished to the
Banks (i) a consolidated balance sheet and income statement of HGC and its
Subsidiaries as at June 30, 1995, and related statements of income and cash
flows for the fiscal year then ended, certified by HGC's independent public
accountants and (ii) an unaudited consolidated balance sheet and income
statement of HGC and its Subsidiaries as at March 31, 1996, and related
unaudited statements of income and cash flows for the fiscal period then ended.
Each of the foregoing were prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
specified and fairly present (subject, in the case of the unaudited financial
statements, to normal, recurring adjustments) the financial position of HGC and
its Subsidiaries as of the dates thereof and the results of the operations and
cash flows of HGC and its Subsidiaries for the fiscal periods then ended. There
were no contingent liabilities of HGC and its Subsidiaries as of such dates
involving material amounts, known to the officers of HGC which were not
disclosed in such balance sheets and the notes related thereto.

            (b) HGC has also previously furnished to the Banks unaudited pro
forma consolidated financial statements of HGC and its Subsidiaries for the
fiscal year ended June 30, 1995, and at December 31, 1995, and for the six-month
period ended on such date. Such financial statements give effect to the
Contribution and the other transactions contemplated under the Purchase
Agreement, were prepared on the basis described in the notes to them, were
prepared in accordance with generally accepted accounting principles and fairly
present the pro forma consolidated assets and liabilities of HGC and its
Subsidiaries and the consolidated results of operations of HGC and its
Subsidiaries, at the dates, and for the periods, to which they relate.

      Section 3.6. Changes. Since June 30, 1995, there have been no changes in
the assets, liabilities, financial condition or business of HGC or its
Subsidiaries, other than changes in the ordinary course of business and the
Contribution, the effect of which has not, in the aggregate, been materially
adverse to the business or financial condition of HGC and its Subsidiaries,
taken as a whole.

      Section 3.7. Taxes. HGC and each of its Subsidiaries has filed all
federal, state and other tax returns required to be filed, and all taxes,

tax liabilities, including those being contested as aforesaid.

      Section 3.8. Litigation. Except as described in Schedule 3.8 attached
hereto (as such Schedule may be supplemented by HGC from time to time with the
consent of the Majority Banks), there is no litigation pending or, to the
knowledge of HGC's officers, threatened against HGC or any Subsidiary of HGC
before any court, tribunal or administrative agency or board which is of a
substantial amount and which, if adversely determined, might reasonably be
expected to materially adversely affect the ability of HGC to perform its
obligations hereunder or under any of the other Loan Documents or in respect of
the Revolving Credit Loans (after taking into account any applicable insurance
coverage).

      Section 3.9. Use of Proceeds; Regulations U and X. The proceeds of the
Revolving Credit Loans will be used for general corporate purposes. No portion
of any Revolving Credit Loan is to be used, and no portion of any Letter of
Credit is to be obtained, for the purpose, whether immediate or ultimate, of
purchasing or carrying any "margin security" or "margin stock," as such terms
are used in Regulations U and X of the Board of Governors of the Federal Reserve
System, 12 C.F.R. Parts 221 and 224 in violation of such regulations. Neither
HGC nor any of its Subsidiaries is engaged principally in or has as one of its
important activities the business of extending credit for the purposes of
purchasing or carrying any such "margin stock".

      Section 3.10. Offering by HGC. Neither HGC nor anyone acting on HGC's
behalf has directly or indirectly offered any interest hereunder or in the
Revolving Credit Notes or any similar security for sale to, or solicited any
offer to buy any thereof from or otherwise negotiated with respect thereto with,
anyone other than the Banks and other banks. Each Bank represents to HGC that it
will not sell or otherwise dispose of any interest in its Revolving Credit Notes
so as to bring the execution and delivery of this Agreement within the
provisions of Section 5 of the Securities Act of 1933, as now in effect or as
later amended. HGC hereby notifies each of the Banks that (a) the transactions
pursuant to which the Revolving Credit Notes will be issued hereunder will not
be registered pursuant to the Securities Act of 1933 or pursuant to any state
statute or regulations governing the sale of securities generally and unless an
exemption from such registration is available, the Revolving Credit Notes must
be held indefinitely, and (b) HGC has no intention to so register in the future.

      Section 3.11. No Default or Violation of Law. Neither HGC nor any of its
Subsidiaries is in violation of any provision of its charter documents or
limited liability company agreement, as the case may be, or by-laws or operating
agreement, as the case may be, or in default in any material respect under any
contract, agreement or obligation to which it may be subject or by which it or
any of its properties may be bound, which default or violation might reasonably
be expected to result in a material impairment of the ability of HGC to fulfill
its obligations hereunder or under the other Loan Documents or a material
impairment of the financial condition or business of HGC and its Subsidiaries,
taken as a whole. Neither HGC nor any Subsidiary of HGC is in violation of any
law, decree, order, judgment, statute, license, rule or regulation applicable to
it or its properties or business operations, which violation might reasonably be
expected to have a material adverse effect on the financial condition or
business of HGC and its Subsidiaries, taken as a whole.
   22
                                      -16-


      Section 3.12. No Default. No Default or event which, with notice or lapse
of time or both, would constitute a Default has occurred and is continuing.

      Section 3.13. Franchises, Patents, Copyrights. HGC and each of its
Subsidiaries possesses all franchises, patents, copyrights, trademarks, trade
names, licenses and permits, and rights in respect of the foregoing, adequate
for the conduct of its business substantially as now conducted without known
conflict with any rights of others.

      Section 3.14. No Materially Adverse Contracts. Neither HGC nor any of its
Subsidiaries is subject to any charter, corporate or other legal restriction, or
any judgment, decree, order, rule or regulation that is expected in the future
to have a materially adverse effect on the business, assets or financial
condition of HGC and its Subsidiaries, taken as a whole. Neither HGC nor any of
its Subsidiaries is a party to any contract or agreement that is expected, in
the judgment of HGC's officers, to have any materially adverse effect on the
business of HGC and its Subsidiaries, taken as a whole.

      Section 3.15. Holding Company and Investment Company Acts. Neither HGC nor
any of its Subsidiaries is a "holding company", or a "subsidiary company" of a
"holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is it an
"investment company", or an "affiliated company" or a "principal underwriter" of
an "investment company", as such terms are defined in the Investment Company Act
of 1940.

      Section 3.16. Certain Transactions. Except for arm's length transactions
pursuant to which HGC or any of its Subsidiaries makes payments in the ordinary
course of business upon terms no less favorable than such entity could obtain
from third parties and for transactions disclosed in HGC's financial statements
or public filings, none of the officers, directors, Shareholders (as defined
below), or employees of HGC or any of its Subsidiaries is presently a party to
any transaction with HGC or any of its Subsidiaries (other than as Shareholders,
or for services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director, Shareholder, or employee
or, to the knowledge of HGC, any corporation, partnership, trust or other entity
in which any officer, director, Shareholder, or any such employee has a
substantial interest or is an officer, director, trustee or partner. For
purposes hereof, the term "Shareholder" shall mean, with respect to HGC and its
Subsidiaries other than Hudson General LLC, those shareholders of such entity
who have filed with the Securities and Exchange Commission Schedules 13D or 13G
pursuant to the Securities Exchange Act of 1934, as amended and, with respect to
Hudson General LLC, any Member of Hudson General LLC (as defined in such
entity's Limited Liability Company Agreement) and those shareholders of any
Member of Hudson General LLC who have filed with the Securities and Exchange
Commission Schedules 13D or 13G with respect to the securities of such Member of
Hudson General LLC pursuant to the Securities Exchange Act of 1934, as amended.

      Section 3.17.  Employee Benefit Plans.

            (a) In General. Each Employee Benefit Plan has been maintained and
operated in compliance in all material respects with the provisions of ERISA
and, to the extent applicable, the Code, including but not limited to the
provisions thereunder respecting prohibited transactions.

            (b) Terminability of Welfare Plans. Under each Employee Benefit Plan
which is an employee welfare benefit plan within the meaning of Section 3(1) or
Section 3(2)(B) of ERISA, no benefits are due unless the event giving rise to
the benefit entitlement occurs prior to plan termination (except as required by
Title I, Part 6 of ERISA). HGC or an ERISA Affiliate, as appropriate, may
terminate each such Plan at any time (or at any time subsequent to the
expiration of any applicable bargaining agreement) in the discretion of HGC or
such ERISA Affiliate without liability to any Person.

            (c) Guaranteed Pension Plans. Each contribution required to be made
to a Guaranteed Pension Plan, whether required to be made to avoid the
incurrence of an accumulated funding deficiency, the notice or lien provisions
of Section 302(f) of ERISA, or otherwise, has been timely made. No waiver of an
accumulated funding deficiency or extension of amortization periods has been
received with respect to any Guaranteed Pension Plan. Except for any ERISA
Reportable Event arising in connection with the Hudson General Corporation
Pension Plan terminated as of June 30, 1992, no liability to the PBGC (other
than required insurance premiums, all of which have been paid) has been incurred
by HGC or any ERISA Affiliate with respect to any Guaranteed Pension Plan and
there has not been any ERISA Reportable Event. Based on the latest valuation of
each Guaranteed Pension Plan (which in each case occurred within twelve months
of the date of this representation), and on the actuarial methods and
assumptions employed for that valuation, the aggregate benefit liabilities of
all such Guaranteed Pension Plans within the meaning of Section 4001 of ERISA
did not exceed the aggregate value of the assets of all such Guaranteed Pension
Plans, disregarding for this purpose the benefit liabilities and assets of any
Guaranteed Pension Plan with assets in excess of benefit liabilities, by more
than $1,000,000.

            (d) Multiemployer Plans. Neither HGC nor any ERISA Affiliate has
incurred any material liability (including secondary liability) to any
Multiemployer Plan as a result of a complete or partial withdrawal from such
Multiemployer Plan under Section 4201 of ERISA or as a result of a sale of
assets described in Section 4204 of ERISA. Neither HGC nor any ERISA Affiliate
has been notified that any Multiemployer Plan is in reorganization or insolvent
under and within the meaning of Section 4241 or Section 4245 of ERISA or that
any Multiemployer Plan intends to terminate or has been terminated under
Section 4041A of ERISA.

      Section 3.18. Environmental Compliance. (a) None of HGC, its Subsidiaries
or any operator of the Real Estate is in material violation, or alleged material
violation, of any judgment, decree, order, law, license, rule or regulation
pertaining to environmental matters, including without limitation, those arising
under the Resource Conservation and Recovery Act ("RCRA"), the Comprehensive
Environmental Response, Compensation and Liability Act of 1980 as amended
("CERCLA"), the Superfund
   24
                                      -18-


Amendments and Reauthorization Act of 1986 ("SARA"), the Federal Clean Water
Act, the Federal Clean Air Act, the Toxic Substances Control Act, or any
federal, state or local statute, regulation, ordinance, order or decree relating
to health, safety or the environment (hereinafter "Environmental Laws"), which
violation could reasonably be expected to have a material adverse effect on the
business, assets or financial condition of HGC and its Subsidiaries, taken as a
whole, other than those violations which have been concluded prior to the date
hereof.

            (b) Except as set forth on Schedule 3.18(b) attached hereto (as such
Schedule may be supplemented by HGC from time to time with the consent of the
Majority Banks), neither HGC nor any of its Subsidiaries has received notice
from any third party including, without limitation, any federal, state or local
governmental authority: (i) that any one of them has been identified by the
United States Environmental Protection Agency ("EPA") as a potentially
responsible party under CERCLA with respect to a site listed on the National
Priorities List, 40 C.F.R. Part 300 Appendix B (1986); (ii) that any hazardous
waste, as defined by 42 U.S.C. Section 9601(5), any hazardous substances as
defined by 42 U.S.C. Section 9601(14), any pollutant or contaminant as defined
by 42 U.S.C. Section 9601(33) and any toxic substances, oil or hazardous
materials or other chemicals or substances regulated by any Environmental Laws
("Hazardous Substances") which any one of them has generated, transported or
Disposed of has been found at any site at which a federal, state or local agency
or other third party has conducted or has ordered that HGC or any of its
Subsidiaries conduct a remedial investigation, removal or other response action
pursuant to any Environmental Law; or (iii) that it is or shall be a named party
to any claim, action, cause of action, complaint, or legal or administrative
proceeding (in each case, contingent or otherwise) arising out of any third
party's incurrence of costs, expenses, losses or damages of any kind whatsoever
in connection with the Release of Hazardous Substances which might reasonably be
expected to have a material adverse effect on the assets, business or financial
condition of HGC and its Subsidiaries, taken as a whole.

            (c) Each of HGC and its Subsidiaries have handled the processing,
storage or Disposal of Hazardous Substances in material compliance with all
applicable Environmental Laws; and, (i) except as set forth on Schedule 3.18(c)
attached hereto (as such Schedule may be supplemented by HGC from time to time

with applicable law, without the consent of the Majority Banks and (B) with
respect to disclosure of all other matters, with the consent of the Majority
Banks), no underground tanks or other underground storage receptacles for
Hazardous Substances are located on any portion of the Real Estate owned by HGC
or any of its Subsidiaries or where HGC any of its Subsidiaries is responsible
for the maintenance or replacement of any such tanks; (ii) in the course of any
activities conducted by HGC, Subsidiaries of HGC or operators of its Real
Estate, no Hazardous Substances have been generated or are being used on the

upon, from or into any Real Estate or real property in the vicinity of any of
the Real Estate which, through soil or groundwater contamination, may have come
to be located on any of the Real Estate, and which might reasonably be
   25
                                      -19-


expected to have a material adverse effect on the value of, all of the Real
Estate or on the business or financial condition of HGC and its Subsidiaries,
taken as a whole; and (iv) in addition, any Hazardous Substances that have been
generated by HGC or any of its Subsidiaries on any of the Real Estate have in
all material respects to the extent required by law or regulation been
transported offsite for treatment or disposal and, to the best of HGC's
knowledge, without having made any special investigation other than to review
the information and documents supplied to HGC by carriers employed by HGC with
respect to such matters, have been transported only by carriers having an
identification number issued by the EPA and have been treated or disposed of
only by treatment or disposal facilities maintaining permits as required under
applicable Environmental Laws.

Banks in respect of the principal of and interest on the Revolving Credit Notes

Banks in writing within fifteen (15) days of becoming aware of any material

proceedings or any material change in any existing litigation affecting HGC or
any of its Subsidiaries or to which HGC or any of its Subsidiaries is or becomes
a party involving an uninsured claim against HGC or any of its Subsidiaries that
could reasonably be expected to have a materially adverse effect on HGC and its
Subsidiaries, taken as a whole and stating the nature and status of such
litigation or proceedings or nature of the material change in such existing
litigation or proceedings, as the case may be. HGC will, and will cause each of

maintenance of any of its properties or any of those of its Subsidiaries if such
discontinuance is, in the judgment of HGC, desirable in the conduct of its or
their business and that do not in the aggregate materially adversely affect the
business of HGC and its Subsidiaries on a consolidated basis.

that HGC or any of its Subsidiaries may fulfill any of its obligations hereunder

Agreement to which HGC or such Subsidiary is a party, HGC will, or (as the case

                                       33


may be) will cause such Subsidiary to, immediately take or cause to be taken all

respect of each Guaranteed Pension Plan and (ii) promptly upon receipt or
dispatch, furnish to the Agent any notice, report or demand sent or received in
respect of a Guaranteed Pension Plan under Sections 302, 4041, 4042,

                           (ii) permit any Guaranteed Pension Plan to incur an
         "accumulated funding deficiency", as such term is defined in Section 
         302 of ERISA, whether or not such deficiency is or may be waived; or

                           (iii) fail to contribute to any Guaranteed Pension
         Plan to an extent which, or terminate any Guaranteed Pension Plan in a
         manner which, could result in the imposition of a lien or encumbrance
         on the assets of HGC or any of its Subsidiaries pursuant to Section 
         302(f) or Section 4068 of ERISA; or

                           (iv) permit or take any action which would result in
         the aggregate benefit liabilities (with the meaning of Section 4001 of
         ERISA) of all Guaranteed Pension Plans exceeding the value of the
         aggregate assets of such Plans, disregarding for this purpose the
         benefit liabilities and assets of any such Plan with assets in excess
         of benefit liabilities, by more than the amount set forth in Paragraph
         3.17(c).

         Section 5.21. Cash Investment in the Kohala Joint Venture. It will not,
as at the end of any fiscal year, permit the Net Cash Investment for the fiscal
year ending on such date to exceed the Net Cash Investment as at the end of the
immediately preceding fiscal year for the fiscal year ending on such date by
more than $2,000,000; and it will not, at any time during the term of this
Agreement, permit the Net Cash Investment for the period commencing on July 1,
1996 and ending on such date of determination to exceed the Net Cash Investment
on July 1, 1996 by more than $5,000,000.

         Section 5.22. Use of Proceeds. HGC will use the proceeds of the
Revolving Credit Loans solely for the purposes set forth in Paragraph 3.9
hereof. HGC will obtain Letters of Credit solely for the purposes set forth in
Paragraph 1.7 hereof.
   40
                                       34


         Section 5.23. Collateral Security. At all times prior to the Collateral
Release Date, the Obligations shall be secured by all of the membership units of
Hudson General LLC owned directly or indirectly by HGC. From and after the
Collateral Release Date, the Computed Value (as defined below) of the Pledged
Units plus the aggregate amount of cash collateral and marketable securities
pledged by HGC to the Collateral Agent pursuant to Paragraph 10(c) hereof shall
not at any time be less than 250% of the Aggregate Loan Limit. For purposes of
this Paragraph 5.23 and Paragraph 10 hereof, the Computed Value of each Pledged
Unit on any date of determination shall be the "Computed Value" of Hudson
General LLC and its Subsidiaries on such date, as calculated pursuant to
Paragraph 3.3(b) of the Purchase Agreement as in effect on the Effective Date,
divided by the number of units of Hudson General LLC outstanding on such date,
provided that if all of the Banks and the Agent reasonably determine at any time
that the calculation of the Computed Value of Hudson General LLC as set forth in
the Purchase Agreement does not accurately reflect the Computed Value of Hudson
General LLC at such time, then the Banks and the Agent shall notify HGC of such
fact. HGC, the Banks and the Agent shall thereafter attempt to negotiate a
formula to determine the Computed Value of Hudson General LLC. If HGC, the Banks
and the Agent are unable to agree on a new formula within sixty days of the day
on which HGC receives such notice, then commencing on such date the Computed
Value of the Pledged Units shall be the net book value of such units, determined
in accordance with generally accepted accounting principles.

         Section 5.24. Limited Liability Agreement. HGC will not, and will not
permit Hudson General LLC to, effect or permit any change in or amendment to the
terms of its Limited Liability Company Agreement if such change or amendment
would have a material adverse effect on HGC or the interests of the Banks
hereunder or under any of the other Loan Documents.

         Section 5.25. Further Assurances. HGC will, and will cause each of its
Subsidiaries to, execute and deliver any and all such instruments and documents,
and take all such other action, as may reasonably be required by the Agent in
order to perfect, insure and continue the rights, interests and powers of the
Agent in respect of any collateral for the Revolving Credit Loans and the
Revolving Credit Notes and the rights and interests of the Banks under this
Agreement.

         Section 6. DEFAULTS. If any of the following events (each a "Default")

Credit Loans when due (whether at any stated maturity date therefor or upon

majority of those individuals who were members of the board of directors of HGC
on the first day of such period or a majority of the directors of HGC appointed

         Section 6.12. with respect to any Guaranteed Pension Plan, an ERISA
Reportable Event shall have occurred and the Majority Banks shall have
determined in their reasonable discretion that such event reasonably could be
expected to result in liability of HGC or any of its Subsidiaries to the PBGC or
such Guaranteed Pension Plan in an aggregate amount exceeding $1,000,000 and
such event in the circumstances occurring reasonably could constitute grounds
for the termination of such Guaranteed Pension Plan by the PBGC or for the

under any of Paragraph 6.8 or Paragraph 6.9, the Banks' Commitment shall

participation of the Banks shall be relieved of all further obligations to
issue, extend or renew Letters of Credit and all amounts owing with respect to
the Revolving Credit Notes and under this Agreement shall forthwith become due
and payable, and (c) in every other such event, and so long as such Default is
continuing, the Agent shall, if so directed by the Majority Banks, by notice in
writing to HGC, terminate immediately the Banks' Commitment and the obligation
of the Letter of Credit Bank with the pro rata participation of the Banks, to
issue, extend or renew Letters of Credit and declare all amounts owing with
respect to the Revolving Credit Notes and under this Agreement to be, and the
Revolving Credit Notes and such amounts shall thereupon forthwith become, due

Default the Agent may demand that cash or other readily marketable securities
acceptable to it in an amount equal to the Maximum Drawing Amount of all then
outstanding Letters of Credit be deposited with the Agent in pledge pursuant to
pledge agreements in form and substance satisfactory to the Agent, as collateral
security for all obligations of HGC to the Banks hereunder. HGC agrees to either
make such deposit with the Agent immediately upon such demand or cause such
Letters of Credit to be cancelled and returned to the Letter of Credit Bank
undrawn. Except as expressly provided above in this Paragraph 6, presentment,
demand, protest or other notice of any kind are hereby expressly waived. Nothing
herein contained shall in any way impair the right of any Bank to enforce
payment of its Revolving Credit Note when due. In case any one or more of the
Defaults shall have occurred and be continuing, and whether or not the Banks
shall have accelerated the maturity of the Revolving Credit Loans pursuant to
this Paragraph 6, each Bank, if owed any amount with respect to the Revolving
Credit Loans, may proceed to protect and enforce its rights by suit in equity,
action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Agreement and the
other Loan Documents or any instrument pursuant to which the Obligations to such
Bank are evidenced, including as permitted by applicable law the obtaining of
the ex parte appointment of a receiver, and, if such amount shall have become
due, by declaration or otherwise, proceed to enforce the payment thereof or any
other legal or equitable right of such Bank. No remedy herein conferred upon any
Bank or the Agent or the holder of any Revolving Credit Note is intended to be
exclusive of any other remedy and each and every remedy shall be cumulative and
shall be in addition to every other remedy given hereunder or now or hereafter
existing at law or in equity or by statute or any other provision of law.

         Section 7. AGENT'S RELATIONSHIP WITH BANKS; AGENT'S DUTIES. Each of the
Banks irrevocably authorizes the Agent to receive all payments of principal of
and interest on the Revolving Credit Loans and of commitment fees, and to take
all other action delegated to it hereunder or reasonably incidental thereto. The
Agent may exercise its powers and execute its duties by or through employees or
agents and shall be entitled to take, and to rely on, advice of counsel
concerning all matters pertaining to its rights and duties under this Agreement
and the other Loan Documents. Neither
   44
                                       38


the Agent nor any of its shareholders, directors, officers or employees nor any
other person assisting it in its duties nor any agent or employee thereof shall
be liable for any waiver, consent or approval given or any action taken or
omitted to be taken in good faith by it or them in connection herewith, or be
responsible for the consequence of any oversight or error of judgment
whatsoever, except that the Agent or such other person, as the case may be,
shall be liable for losses due to its own gross negligence or willful
misconduct. The Agent shall not be responsible for the execution or validity or
enforceability of this Agreement or any of the other Loan Documents, or for any
recitals or statements, warranties or representations herein or made in any
certificate or instrument hereafter furnished to it by or on behalf of HGC, or
be bound to ascertain or inquire as to the performance or observance of any of
the terms, conditions, covenants or agreements herein or in any other Loan
Document. The Agent shall not be bound to ascertain whether any notice, consent,
waiver or request delivered to it by HGC or by any Bank owed amounts with
respect to the Loans shall have been duly authorized or is true, accurate or
complete. HGC shall certify to the Agent the names and signatures of its
officers authorized to execute certificates and otherwise act in respect hereof,
and the Agent may conclusively rely thereon until receipt by it of notice to the
contrary. The Agent has not made nor does now make any representations or
warranties, express or implied, nor does it assume any liability to the Banks,
with respect to the credit worthiness or financial condition of HGC or any
Subsidiary of HGC. Each Bank acknowledges that it has, independently and without
reliance upon the Agent or any other Bank, and based upon such information and
documents as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. If in the opinion of the Agent the
distribution of any amount received by it in such capacity hereunder might
involve it in a dispute resulting in its liability, it may refrain from making
distribution until its right to make distribution shall have been adjudicated by
a court of competent jurisdiction. If a court of competent jurisdiction shall
adjudge that any amount received and distributed by the Agent is to be repaid,
each person to whom any such distribution shall have been made shall either
repay to the Agent its proportionate share of the amount so adjudged to be
repaid or pay over the same in such manner and to such persons as shall be
determined by such court. FNB shall have the same obligations and the same
rights, powers and privileges with respect to its Commitment and the Revolving
Credit Loans as it would have were it not also the Agent. The Agent may resign
as Agent for the Banks upon thirty days' written notice to HGC and each Bank,
whereupon a new agent shall be appointed by the Banks. The Agent may be removed
as Agent for the Banks upon thirty days' written notice to HGC and the Agent
from the Majority Banks, whereupon a new Agent shall be appointed by the Banks.
The Banks (including FNB) ratably agree hereby to indemnify and hold harmless
the Agent from and against any and all claims, actions and suits (whether
groundless or otherwise), losses, damages, costs, expenses (including any
expenses for which the Agent has not been reimbursed by HGC as required by
Paragraph 11.5), and liabilities of every nature and character arising out of or
related to this Agreement or the other Loan Documents, or the transactions
contemplated or evidenced hereby or thereby, or the Agent's actions taken
hereunder or thereunder, except to the extent that any of the same shall be
directly caused by the Agent's willful misconduct or gross negligence. The Agent
shall not take any actions with respect to any Default unless it shall have
received such instructions from the Majority Banks. The Collateral Agent shall
not exercise any remedy under
   45
                                       39


any Security Document unless it shall have received such instructions as are
required by the Intercreditor Agreement.

         Section 8. SETOFF. HGC grants to each of the Banks, as security for the
full and punctual payment and performance of its obligations hereunder, a
continuing lien and security interest in all deposits or other sums credited by
or due from any Bank to HGC and all securities or other property of HGC in the
possession of such Bank and, regardless of the adequacy of any collateral, such
sums at any time may be applied to or set off by such Bank against any and all
liabilities, direct or indirect, absolute or contingent, due or to become due,
now existing or hereafter arising, of HGC to such Bank. The offsetting Bank
shall provide HGC with prompt notice of any such action. Each Bank agrees with
the other Banks that (a) if any deposits or other sums credited by or due from
such Bank to HGC are applied to indebtedness of HGC to such Bank, other than
amounts owing with respect to the Revolving Credit Loans, such amount shall be
applied ratably to such other indebtedness and to the amounts owing with respect
to the Revolving Credit Loans, and (b) if such Bank (i) shall receive any
payment from HGC, whether by distributions made by the Agent, voluntary payment,
exercise of the right of setoff (including, but not limited to, a secured claim
under Section 506 of Title II of the United States Code or other security or
interest arising from, or in lieu of, such secured claim, received by such Bank
under any applicable bankruptcy, insolvency or other similar law), counterclaim,
cross action or enforcement of any claim with respect to the Revolving Credit
Loans by proof thereof in bankruptcy, reorganization, liquidation, receivership
or similar proceedings, or otherwise, and (ii) shall retain and apply to the
payment of such Bank's Revolving Credit Loans any amount in excess of its
ratable portion of the payments received by all Banks with respect to the
Revolving Credit Loans as contemplated hereby, such Bank will make such
disposition and arrangements with the other Banks with respect to such excess,
either by way of distribution, pro tanto assignment of claims, subrogation or
otherwise, as shall result in each Bank's receiving in respect of the Revolving
Credit Loans its proportionate payment as contemplated hereby.

         Section 9. INDEMNIFICATION. HGC agrees to indemnify and hold harmless
the Agent and the Banks from and against any and all claims, actions and suits
whether groundless or otherwise, and from and against any and all liabilities,
losses, damages and expenses of every nature and character arising out of this
Agreement or any of the other Loan Documents or the transactions contemplated
hereby or thereby including, without limitation, (a) any actual or proposed use
by HGC or any Subsidiary of HGC of the proceeds of any of the Revolving Credit
Loans or Letters of Credit, (b) HGC or any Subsidiary of HGC entering into or
performing this Agreement or any of the other Loan Documents or (c) with respect
to HGC and Subsidiaries of HGC and their respective properties and assets, (i)
the violation of any Environmental Law, (ii) the presence, Disposal, escape,
seepage, leakage, spillage, discharge, emission, Release or threatened Release
of any Hazardous Substances, (iii) the investigation or remediation of offsite
locations at which HGC, any Subsidiary of HGC or any of such Person's
predecessors are alleged to have directly or indirectly Disposed of Hazardous
Substances or (iv) any action, suit, proceeding or investigation brought or
threatened with respect to any Hazardous Substances (including, but not limited
to, claims with respect to wrongful death, personal injury or damage to
property), in each case
   46
                                       40


including, without limitation, the reasonable fees and disbursements of counsel
and allocated costs of internal counsel incurred in connection with any such
investigation, litigation or other proceeding (but excluding any such
liabilities, losses, damages and expenses incurred by any of the Agent or any
Bank by reason of the gross negligence or willful misconduct of the Agent or any
Bank). In litigation, or the preparation therefor, the Banks and the Agent shall
be entitled to select their own counsel and, in addition to the foregoing
indemnity, HGC agrees to pay promptly the reasonable fees and expenses of such
counsel. If, and to the extent that the obligations of HGC under this Paragraph
9 are unenforceable for any reason, HGC hereby agrees to make the maximum
contribution to the payment in satisfaction of such obligations which is
permissible under applicable law. The covenants contained in this Paragraph 9
shall survive payment or satisfaction in full of all other Obligations.

         Section 10. SECURITY AND GUARANTIES. (a) The Obligations shall be
secured by a perfected first priority security interest in and pledge of all of
the membership units of Hudson General LLC (or, from and after the Collateral
Release Date, solely by cash and marketable securities or that number of
membership units of Hudson General LLC necessary for compliance by HGC with
Paragraph 5.23 hereof) owned directly or indirectly by HGC (the "Pledged Units")
and the other Collateral pursuant to and to the extent required by the terms of

provided are cumulative and not exclusive of any rights or remedies otherwise
provided by law.

expenses and disbursements, each Bank shall pay to the Agent, promptly upon

any provision of this Agreement or the Revolving Credit Notes may be granted or
effected, with the consent of HGC, by one or more substantially concurrent
written instruments signed by the Majority Banks; provided, however, that no
such consent shall be effective to (a) increase the Aggregate Loan Limit or any
Bank's Commitment without the consent of such Bank, or (b) reduce the amount of
any payment of principal or rate of interest on any Revolving Credit Note or
postpone any date fixed for the payment of any principal of or interest on any
Revolving Credit Note without the consent of the holder thereof (except by
waiver after acceleration pursuant to Paragraph 6), or (c) modify this Paragraph

successors and assigns, provided that HGC may not assign or transfer its rights
hereunder.

be signed in any number of counterparts with the same effect as if the
signatures hereto and thereto were upon the same instrument. Complete sets of
counterparts shall be lodged with HGC and the Agent. In proving this Agreement
it shall not be necessary to produce or account for more than one counterpart
signed by the party against whom enforcement is sought.

         Section 11.10. Entire Agreement. This Agreement and the other Loan
Documents express the entire understanding of the parties with respect to the
transactions contemplated hereby.

         Section 11.11. Assignments or Participations by Banks or Affiliates.
Each Bank may assign to one or more banks or other financial institutions having
total capital and surplus of $100,000,000 or more, and otherwise reasonably
acceptable to HGC (which acceptance shall be in writing) all or any part of, or
(without the consent of HGC) may grant participations to one or more of such
banks or financial institutions in or to all or any part of, any Revolving
Credit Loan or Revolving Credit Loans owing to such Bank and the Revolving
Credit Notes held by such Bank, provided that, following the consummation of any
such assignment or participation, such Bank's or bank's Commitment Percentage
shall not be less than 10%, and to the extent of any such assignment or
participation (unless otherwise stated therein), the assignee or participant of
such assignment or participation shall have the same rights and benefits
hereunder and under such Revolving Credit Note as it would have if it were such
Bank hereunder. In the event of such assignment HGC will consent, such consent
not to be unreasonably withheld, to release the assigning Bank from the
obligations hereunder to the extent of such assignment and to sign and deliver
any releases or documents necessary to effectuate such assignment as such Bank
shall reasonably request. Notwithstanding Paragraph 11.6 hereof, each Bank may
disclose any information concerning HGC or the credit facilities to any such
bank or financial institution,
   50
                                       44


provided that such bank or financial institution agrees to be bound by the
provisions of Paragraph 11.6 hereof. It shall be a condition of any assignment
as described in this Paragraph 11.11, that (a) such assignee provide a written
acknowledgment, in form and substance reasonably acceptable to the Agent and its
special counsel and HGC and its counsel, that such assignee assumes the
obligations and the rights of the assigning Bank under this Agreement and the
other Loan Documents and, if such assignee is not organized under the laws of
the United States or any state thereof, that such assignee shall provide the
Agent and HGC with satisfactory evidence that any payments made to the assignee
hereunder may be made free and clear of any withholding taxes and (b) such
assignee or an affiliate thereof accepts an assignment from the assigning Bank
(or an affiliate thereof) of a pro rata portion of such Bank's interest in the
Aviation Loans and the revolving credit loans made to Hudson General LLC under
the Hudson General LLC Credit Agreement. Notwithstanding anything contained in
this Paragraph 11.11 to the contrary, upon the occurrence and during the
continuance of a Default, each Bank may make assignments or grant participations
hereunder without the consent of HGC. HGC agrees, at its own expense, to execute
and deliver to the assignee Bank, in exchange for each surrendered Revolving
Credit Note of the assigning Bank, a new Revolving Credit Note to the order of
such assignee Bank in an amount equal to the amount assumed by such Bank and, if
the assigning Bank has retained some portion of its obligations hereunder, a new
Revolving Credit Note to the order of the assigning Bank in an amount equal to
the amount retained by it hereunder. Such new Revolving Credit Notes shall
provide that they are replacements for the surrendered Revolving Credit Notes,
shall be in an aggregate principal amount equal to the aggregate principal
amount of the surrendered Revolving Credit Notes, shall be dated the effective
date of such assignment and shall otherwise be in substantially the form of the
assigned Revolving Credit Notes.

         Section 11.12. Term of Agreement. This Agreement shall continue in full
force and effect from the date hereof so long as any commitment to lend any
principal with respect to the Revolving Credit Loans or any commitment to issue
any Letter of Credit or any obligation of HGC for any interest or commitment or
other fee or obligation hereunder or on the Revolving Credit Notes shall be
outstanding.

                            FORM OF PLEDGE AGREEMENT


         This PLEDGE AGREEMENT dated as of June 1, 1996, is between HUDSON
GENERAL CORPORATION (the "Pledgor"), a Delaware corporation, and THE FIRST
NATIONAL BANK OF BOSTON, a national banking association, as collateral agent

         WHEREAS, the Pledgor has entered into a Revolving Credit Agreement,

"HGC Credit Agreement"), with The First National Bank of Boston, European
American Bank, The Chase Manhattan Bank, N.A., certain other financial
institutions (collectively, the "Banks") and The First National Bank of Boston
as agent, pursuant to which the Banks, subject to the terms and conditions
contained therein, have agreed to make loans or otherwise to extend credit to
the Pledgor; and

         WHEREAS, the Pledgor has entered into an Amended and Restated Revolving
Credit Agreement, dated as of November 25, 1992 and amended and restated as of
the date hereof (as amended and in effect from time to time, the "LLC Credit
Agreement"), with Hudson General LLC (the "Company"), the Banks and The First
National Bank of Boston, as agent, pursuant to which the Banks, subject to the
terms and conditions contained therein, have agreed to make loans or otherwise
to extend credit to the Pledgor and the Company; and

         WHEREAS, it is a condition precedent to the Banks' making any loans or
otherwise extending any credit to the Pledgor under the HGC Credit Agreement or
the LLC Credit Agreement that the Pledgor execute and deliver to the Collateral
Agent, for the benefit of the Banks and the Collateral Agent, a pledge agreement
in substantially the form hereof; and

         WHEREAS, the Pledgor wishes to grant security interests in favor of the

         NOW, THEREFORE, in consideration of the promises contained herein and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

         SECTION 1. DEFINITIONS. The term "Collateral" as used herein means the

Agreement.
   64
                                       -2-



        SECTION 2. PLEDGE OF INTERESTS. (a) To secure the due and prompt payment
and performance of the Obligations (as defined below), the Pledgor hereby
pledges, assigns, grants a continuing security interest in and lien on, and
delivers to the Collateral Agent, all right, title and interest of the Pledgor,
whether now existing or hereafter arising, in and to the Company as a member of
the Company, including, without limitation, the membership interests described
on Schedule 1 attached hereto (the "Pledged Interests") (as such schedule may be
amended and supplemented from time to time by the Pledgor with the consent of
the Banks in accordance with Paragraph 5.23 and Paragraphs 10(c) and 10(d) of
the HGC Credit Agreement), and, in each case, all rights to receive any
distributions or payments due or to become due to the Pledgor in respect of the
Pledged Interests under the terms of the Company's certificate of formation and
Limited Liability Company Agreement and all other economic benefits of the
Pledgor's interest in the Company, whether cash, property or otherwise, at any
time owing or payable to the Pledgor on account of the Pledged Interests, and
the right, but not the obligation to become a substitute member of the Company.
This pledge and security interest is for collateral purposes only, and the
Collateral Agent shall not, by virtue of this Agreement, or its receipt of any
distributions or other amounts from the Company, be deemed to be a member of the
Company, or to have assumed or become liable for any obligation of the Company
or the Pledgor.

                  (b) In case the Pledgor shall acquire, prior to the Collateral
Release Date, any additional membership interests of the Company (other than
membership interests received from the Company in order for the Pledgor to
satisfy its obligations under Article III of the Purchase Agreement) or any
securities exchangeable for or convertible into membership interests of the
Company, whether by purchase, dividend, distribution of capital or otherwise,
the Pledgor shall forthwith deliver to and pledge such membership interests or
other securities to the Collateral Agent under this Agreement. The Pledgor
agrees that the Collateral Agent may from time to time attach as Schedule 1
hereto an updated list of the membership interests at such time pledged
hereunder.

         SECTION 3. PRO-RATA SECURITY FOR OBLIGATIONS. (a) This Agreement and
the pledge of the Collateral hereunder is made with the Collateral Agent as
security for (i) all obligations of the Pledgor to the Banks and the Agent under
or in relation to the HGC Credit Agreement, the promissory notes executed and
delivered by the Pledgor to the Banks in connection therewith and the other Loan
Documents, as such instruments are originally executed or as modified, amended,
restated, supplemented or extended, (ii) prior to the Collateral Release Date,
all of the obligations of the Pledgor and the Company (whether or not the HGC
Release Date (as defined in the LLC Credit Agreement) has occurred) to the Banks
and the Agent under or in relation to the LLC Credit Agreement, the promissory
notes executed and delivered by HGC and the Company to the Banks in connection
therewith and the other Loan Documents (as defined in the LLC Credit Agreement),
as such instruments are originally executed or as modified, amended, restated,
supplemented or extended, and (iii) all obligations of the Pledgor to the Banks
arising out of any extension, refinancing or refunding of any of the foregoing
obligations, whether such obligations are now existing or hereafter acquired or
arising, direct or indirect, joint or several, absolute or contingent, due or to
   65
                                       -3-


become due, matured or unmatured, liquidated or unliquidated, arising by
contract, operation of law or otherwise (the foregoing obligations shall be
referred to herein, collectively, as the "Obligations").

                  (b) All amounts owing with respect to the Obligations shall be
secured pro rata by the Collateral without distinction as to whether some
Obligations are then due and payable and other Obligations are not then due and
payable. Upon any realization upon the Collateral by the Collateral Agent,
whether by receipt of dividends pursuant to Section 7 hereof or upon sale of all
or part of the Collateral pursuant to Section 8 hereof or otherwise, the Pledgor
agrees that the proceeds thereof shall be applied as set forth in Paragraph
10(e) of the HGC Credit Agreement (whether or not such agreement is then in
effect).

         SECTION 4. LIQUIDATION, RECAPITALIZATION. Any sums paid upon or with
respect to any of the Pledged Interests upon the liquidation or dissolution of
the Company shall be paid over to the Collateral Agent to be held by it as
security for the Obligations; and in case any distribution of capital shall be
made on or in respect of any of the Pledged Interests or any property shall be
distributed upon or with respect to any of the Pledged Interests pursuant to the
recapitalization or reclassification of the capital of the issuer thereof or
pursuant to the reorganization of such issuer, the property so distributed shall
be delivered to the Collateral Agent to be held by it as security for the
Obligations. All sums of money and property paid or distributed in respect of
the Pledged Interests upon such a liquidation, dissolution, recapitalization or
reclassification which are received by the Pledgor shall, until paid or
delivered to the Collateral Agent, be held in trust for the Collateral Agent as
security for the Obligations.

         SECTION 5. WARRANTY OF OWNERSHIP; CAPITALIZATION. (a) The Pledgor
warrants that it is the sole record and beneficial owner of the Pledged
Interests described in Section 2 hereof, subject to no pledges, liens, security
interests, charges, options, restrictions or other encumbrances except for the
security interest created by this Agreement and the option granted to LAGS as
set forth in the Purchase Agreement, and that it has the power, authority and
legal right to pledge all of such Pledged Interests pursuant to this Agreement.

                  (b) The Pledgor covenants that it will not, and will not
permit the Company to, authorize, issue or sell any membership interests in the
Company, or grant any options, warrants or other rights to purchase any
membership interests in the Company except for the option granted to LAGS (or an
affiliate of LAGS) under Article III of the Purchase Agreement and the issuance
by the Company of membership interests to LAGS (or an affiliate of LAGS) in
connection therewith.

                  (c) The Pledgor covenants that it will defend the Collateral
Agent's rights and security interest in such Pledged Interests against the
claims and demands of all persons whomsoever; and the Pledgor covenants that it
will have the like title to and right to pledge any other Collateral and will
likewise defend the Collateral Agent's rights and security interest therein.

                                       -4-



         SECTION 6. CORPORATE POWER, AUTHORITY. The execution and delivery of
this Agreement and pledging of the Pledged Interests described in Section 2
hereof are within the Pledgor's corporate power and have been duly authorized by
all necessary corporate action and such execution and delivery and the pledging
of such Pledged Interests do not contravene any law or any rule or regulation
thereunder or any provision of the charter documents or by-laws of the Pledgor
or of any judgment, decree or order of any tribunal or of any agreement or
instrument to which the Pledgor is a party or by which it or any of its property
is bound or constitute a default thereunder.

         SECTION 7. DISTRIBUTIONS, PRINCIPAL, INTEREST AND VOTING PRIOR TO
DEFAULT. Unless and until a Default shall have occurred and be continuing, the
Pledgor shall be entitled (a) to receive all cash distributions paid in respect
of the Pledged Interests and (b) to vote the Pledged Interests and to give
consents, waivers and ratifications in respect of the Pledged Interests;
provided, however, that no vote shall be cast, or consent, waiver or
ratification given or action taken which would be inconsistent with or violate
any provision of the HGC Credit Agreement, the LLC Credit Agreement (prior to
the Collateral Release Date), any other Security Document or this Agreement.

         SECTION 8. REMEDIES. (a) Upon the occurrence and during the continuance
of a Default, the Collateral Agent shall thereafter have the following rights
and remedies (to the extent permitted by applicable law and subject to
compliance by the Collateral Agent with the provisions of the Company's Limited
Liability Company Agreement) in addition to the rights and remedies of a secured
party under the Uniform Commercial Code of Massachusetts, all such rights and
remedies being cumulative, not exclusive, and enforceable alternatively,
successively or concurrently:

                  (i) if the Collateral Agent so elects and gives notice of such
         election to the Pledgor, the Collateral Agent may vote any or all of
         the Pledged Interests possessing voting rights (whether or not the same
         shall have been transferred into its name or the name of its nominee or
         nominees) and give all consents, waivers and ratifications in respect
         of the Pledged Interests and otherwise act with respect thereto as
         though it were the outright owner thereof, the Pledgor hereby
         irrevocably constituting and appointing the Collateral Agent the proxy
         and attorney-in-fact of the Pledgor, with full power of substitution,
         to do so;

                  (ii) the Collateral Agent may demand, sue for, collect or make
         any compromise or settlement in respect of any Collateral held by it
         hereunder that it deems suitable;

                  (iii) after ten (10) days' notice to the Pledgor and
         compliance by the Collateral Agent with the terms of the Company's
         Limited Liability Company Agreement, the Collateral Agent may sell,
         resell, assign and deliver, or otherwise dispose of any or all of the
         Collateral, for cash and/or credit and upon such terms at such place or
         places and at such time or times and to such persons, firms, companies
         or corporations as the Collateral Agent shall approve, all without
         demand for performance by the Pledgor or advertisement or any further
         notice whatsoever except such as may be required by law; and
   67
                                       -5-


                  (iv) the Collateral Agent may at any time, at its option,
         cause all or any part of the Pledged Interests held by it to be
         transferred into its name or the name of its nominee or nominees,
         receive any income thereon and hold such income as additional
         collateral or apply it to the Obligations.

         (b) Except as otherwise provided herein and in the Company's Limited
Liability Company Agreement, the Collateral Agent may enforce its rights
hereunder without any other notice and without compliance with any other
condition precedent now or hereafter imposed by statute, rule of law or
otherwise (all of which are hereby expressly waived by the Pledgor, to the
fullest extent permitted by law). If any of the Collateral is sold by the
Collateral Agent upon credit or for future delivery, the Collateral Agent shall
not be liable for the failure of the purchaser to pay the same and, in such
event, the Collateral Agent may resell such Collateral. The Collateral Agent may
buy any part or all of the Collateral at any public sale and, if any part or all
of the Collateral is of a type customarily sold in a recognized market or is of
a type which is the subject of widely-distributed standard price quotations, the
Collateral Agent may buy at private sale and may make payments therefor by any
means. The Collateral Agent shall apply the cash proceeds actually received from
any sale or other disposition to the reasonable expenses of retaking, holding,
preparing for sale, selling and the like, to reasonable attorneys' fees, and all
legal expenses, travel and other expenses which may be incurred by the
Collateral Agent in attempting to collect the Obligations or to enforce this
Agreement or in the prosecution or defense of any action or proceeding related
to the subject matter of this Agreement; and then to the Obligations as set
forth in Paragraph 10(e) of the HGC Credit Agreement (whether or not such
agreement is then in effect) and any surplus shall be paid to the Pledgor.

         (c) The Pledgor recognizes that the Collateral Agent may be unable to
effect a public sale of the Pledged Interests by reason of certain prohibitions
contained in the Securities Act of 1933, as amended, but may be compelled to
resort to one or more private sales thereof to a restricted group of purchasers
consistent with applicable laws. The Pledgor agrees that any such private sales
may be at prices and other terms less favorable to the seller than if sold at
public sales and that such private sales shall not by reason thereof be deemed
not to have been made in a commercially reasonable manner. The Collateral Agent
shall be under no obligation to delay a sale of any of the Pledged Interests for
the period of time necessary to permit the issuer of such securities to register
such securities for public sale under the Securities Act of 1933, as amended,
even if the issuer would agree to do so.

         SECTION 9. MARSHALLING. The Collateral Agent shall not be required to
marshal any present or future security for (including but not limited to this
Agreement and the Collateral pledged hereunder), or guaranties of, the
Obligations or any of them, or to resort to such security or guaranties in any
particular order; and all of its rights hereunder and in respect of such
securities and guaranties shall be cumulative and in addition to all other
rights, however existing or arising. To the extent that it lawfully may, the
Pledgor hereby agrees that it will not invoke any law relating to the
marshalling of collateral which might cause delay in or impede the enforcement
of the Collateral Agent's rights under this Agreement or under any other
instrument
   68
                                       -6-



evidencing any of the Obligations or under which any of the Obligations is
outstanding or by which any of the Obligations is secured or guaranteed, and, to
the extent that it lawfully may, the Pledgor hereby irrevocably waives the
benefits of all such laws.

         SECTION 10. PLEDGOR'S OBLIGATIONS NOT AFFECTED. The obligations of the
Pledgor hereunder shall remain in full force and effect without regard to, and
shall not be impaired by (a) any bankruptcy, insolvency, reorganization,
arrangement, readjustment, composition, liquidation or the like of the Pledgor;
(b) any exercise or nonexercise, or any waiver, by the Collateral Agent of any
right, remedy, power or privilege under or in respect of any of the Obligations
or any security thereof (including this Agreement); (c) any amendment to or
modification of the HGC Credit Agreement, the other Loan Documents, the LLC
Credit Agreement, the other Loan Documents (as defined in the LLC Credit
Agreement) or any of the Obligations; (d) any amendment to or modification of
any instrument (other than this Agreement) securing any of the Obligations; or
(e) the taking of additional security for, or any guaranty of, any of the
Obligations or the release or discharge or termination of any security or
guaranty for any of the Obligations; and whether or not the Pledgor shall have
notice or knowledge of any of the foregoing.

         SECTION 11. TRANSFER BY PLEDGOR. Without the prior written consent of
the Collateral Agent, the Pledgor will not sell, assign, transfer or otherwise
dispose of, grant any option with respect to, or pledge or grant any security
interest in or otherwise encumber any of the Collateral or any interest therein,
except for the pledge thereof provided for in this Agreement and except as
provided in the Purchase Agreement.

         SECTION 12. NO FURTHER ACTIONS. No authorization, approval or other
action by, and no notice to or filing with, any governmental authority or other
regulatory body or other person that has not been received, taken or made is
required for the grant by the Pledgor of the security interests granted hereby
or for the execution, delivery or performance of this Agreement by the Pledgor,
or, except for (a) the filing of financing statements and continuation
statements with respect thereto and (b) the delivery of the certificates
representing the Pledged Interests along with the appropriate instruments of
assignment duly executed in blank, for (i) the perfection and maintenance of the
security interests hereunder (including the first priority nature of such
security interests) or (ii) the exercise by the Collateral Agent of the rights
or the remedies in respect of the Collateral pursuant to this Agreement (other
than the authorization of the requisite Banks).

         SECTION 13. FURTHER ASSURANCES. The Pledgor will do all such acts, and
will furnish to the Collateral Agent all such financing statements,
certificates, legal opinions and other documents and will obtain all such
governmental consents and corporate approvals and will do or cause to be done
all such other things as the Collateral Agent may reasonably request from time
to time in order to give full effect to this Agreement and to secure the rights
of the Collateral Agent hereunder.

         SECTION 14. PLEDGEE'S EXONERATION. Under no circumstances shall the
Collateral Agent be deemed to assume any responsibility for, or obligation or
duty with
   69
                                       -7-



respect to, any part or all of the Collateral of any nature or kind, other than
the physical custody thereof, or any matters or proceedings arising out of or
relating thereto. The Collateral Agent shall not be required to take any action
of any kind to collect, preserve or protect its or the Pledgor's rights in the
Collateral or against other persons asserting rights in the Collateral. The
Collateral Agent's prior recourse to any part or all of the Collateral shall not
constitute a condition of any demand, suit or proceeding for payment or
collection of the Obligations.

         SECTION 15. POWER OF ATTORNEY. (a) The Pledgor acknowledges the
Collateral Agent's right, to the extent permitted by applicable law, singly to
execute and file financing or continuation statements and similar notices
required by applicable law, and amendments thereto, concerning the Collateral
without execution by the Pledgor. A carbon, photographic or other reproduction
of this Agreement or any financing statement covering the Collateral or any part
thereof shall be sufficient as a financing statement where permitted by law.

         (b) The Pledgor hereby irrevocably appoints the Collateral Agent as its
attorney-in-fact, effective at all times subsequent to the occurrence and during
the continuance of a Default with full authority in the place and stead of the
Pledgor and in the name of the Pledgor or otherwise, to take any action and to
execute any instrument which the Collateral Agent may reasonably deem necessary
or advisable to accomplish the purpose of this Agreement, including, without
limitation, the power and right (i) to endorse the Pledgor's name on any checks,
notes, acceptances, money orders, drafts, filings or other forms of payment or
security that may come into the Collateral Agent's possession; and (ii) to do
all other things which the Collateral Agent then determines to be necessary to
carry out the terms of this Agreement. The power conferred on the Collateral
Agent hereunder is solely to protect the Collateral Agent's interests in the
Collateral and shall not impose any duty upon the Collateral Agent to exercise
such power.

         SECTION 16. NO WAIVER. No act, failure or delay by the Collateral Agent
shall constitute a waiver of its rights and remedies hereunder or otherwise, nor
shall any single or partial exercise by the Collateral Agent of any right,
remedy or power hereunder preclude any other exercise or future exercise of any
other right, remedy or power. No single or partial waiver by the Collateral
Agent of any default or right or remedy which it may have shall operate as a
waiver of any other default, right or remedy or of the same default, right or
remedy on a future occasion. The Pledgor hereby waives presentment, notice of
dishonor and protest of all instruments included in or evidencing any of the
Obligations or the Collateral, and any and all other notices and demands
whatsoever (except as expressly provided herein).

         SECTION 17. NOTICES. Except as otherwise expressly provided herein, all
notices and other communications made or required to be given pursuant to this
Agreement shall be given in the manner and delivered to addresses of the Pledgor
and the Collateral Agent specified in the HGC Credit Agreement.

         SECTION 18. TERMINATION. (a) Notwithstanding any other provision of
this Agreement and subject to Paragraph 5.23 of the HGC Credit Agreement, the
Pledgor
   70
                                       -8-



shall be entitled to the return, at the Pledgor's expense, of the Collateral
provided by the Pledgor in the possession or control of the Collateral Agent
either (i) upon delivery of a letter addressed to the Collateral Agent and
signed by each of the Banks specifying that the Banks have received evidence
satisfactory to them that (A) all litigation against HGC and Aviation resulting
from or relating to the acquisition in 1984 of certain assets of the airport
ground services business of Innotech Aviation Limited has been fully and finally
dismissed (and such dismissal is not appealable) or settled in full, (B) HGC and
Aviation have satisfied in full all of their payment obligations, if any, with
respect to such litigation, (C) the payment thereof has not resulted in the
occurrence of any Default or condition which would, with either or both the
giving of notice or lapse of time, result in a Default, and (D) no Default or
condition which would, with either or both the giving of notice or lapse of
time, result in a Default then exists or (ii) upon the indefeasible payment and
performance of the Obligations in full.

         (b) Upon the delivery of a letter addressed to the Collateral Agent
signed by the Banks specifying that the Banks have received evidence that the
release of certain of the Collateral is permitted under Paragraph 5.23 and
Paragraph 10(d) of the HGC Credit Agreement (from and after the Collateral
Release Date) or Paragraph 10(c) of the HGC Credit Agreement (subject to the
provisions of such paragraph), the Collateral Agent shall return such Collateral
to the Pledgor and execute and deliver to the Pledgor such releases with respect
to the lien hereof as the Pledgor may reasonably request with respect to such
Collateral.

         SECTION 19. CONSENTS, AMENDMENTS, WAIVERS. Any term of this Agreement
may be amended, and the performance or observance by the Pledgor of any of the
terms of this Agreement may be waived (either generally or in a particular
instance and either retroactively or prospectively) only in accordance with
Paragraph 11.7 of the HGC Credit Agreement or, if the HGC Credit Agreement is no
longer in effect, Paragraph 11.7 of the LLC Credit Agreement.

         SECTION 20. PARTIES IN INTEREST. This Agreement and all obligations of
the Pledgor shall be binding upon the successors and assigns of the parties
hereto, provided, that the Pledgor may not assign or transfer its rights
hereunder without the prior written consent of the Collateral Agent.

         SECTION 21. GOVERNING LAW. This Agreement and the obligations of the
Pledgor hereunder shall be deemed to be a contract under seal and shall for all
purposes be governed by and construed in accordance with the laws of the
Commonwealth of Massachusetts (excluding the laws applicable to conflicts or
choice of law).

         SECTION 22. MISCELLANEOUS PROVISIONS. If any term of this Agreement
shall be held to be invalid, illegal or unenforceable, the validity of all other
terms hereof shall be in no way affected thereby, and this Agreement shall be
construed and be enforceable as if such invalid, illegal or unenforceable term
had not been included herein. The Pledgor acknowledges receipt of a copy of this
Agreement. The descriptive
   71
                                       -9-

section headings have been inserted for convenience of reference only and do not
define or limit the provisions hereof. Terms used herein without definition
which are defined in the Uniform Commercial Code of Massachusetts have such
defined meanings herein, unless the context otherwise indicates or requires.
This Agreement and any amendment hereof may be executed in several counterparts
and by each party on a separate counterpart, each of which when so executed and
delivered shall be an original, but all of which together shall constitute one
instrument. In proving this Agreement it shall not be necessary to produce or
account for more than one such counterpart signed by the party against whom
enforcement is sought.

         IN WITNESS WHEREOF, the Pledgor and the Collateral Agent have caused
this Agreement to be duly executed as an instrument under seal as of the date
first above written.

                           Re:  Hudson General Corporation


Ladies and Gentlemen:

                  I am Vice President-General Counsel of Hudson General
Corporation, a Delaware corporation ("HGC"), and have acted as counsel for HGC
in connection with the execution and delivery by HGC of the Revolving Credit
Agreement, dated as of June 1, 1996 (the "Credit Agreement") among HGC, The
First National Bank of Boston ("FNB"), in its individual capacity, European
American Bank ("EAB"), The Chase Manhattan Bank, N.A. ("Chase", and collectively
with FNB and EAB, the "Banks") and The First National Bank of Boston, as agent
for the Banks (the "Agent"), the Pledge Agreement, dated as of June 1, 1996 (the
"Pledge Agreement"), between HGC and The First National Bank of Boston, as
collateral agent (the "Collateral Agent"), and certain other agreements,
instruments and documents related to the Credit Agreement. This opinion is being
delivered pursuant to Paragraph 4A.4 of the Credit Agreement. Capitalized terms
used and not otherwise defined herein shall have the same meanings herein as in
the Credit Agreement.

                  In rendering the opinions set forth herein, I have examined
originals or copies, certified or otherwise identified to my satisfaction, of
the following:

                  (a) the Credit Agreement;

                  (b) the Revolving Credit Notes, each dated as of June 1, 1996,
issued by HGC to the respective Banks (each a "Note" and collectively, the
"Notes");

                  (c) the Pledge Agreement;

                  (d) the Amended and Restated Revolving Credit Agreement, dated
as of November 25, 1992 and amended and restated as of June 1, 1996 (the "LLC
Credit Agreement") among HGC, Hudson General LLC, a Delaware limited liability
company ("Hudson LLC"), the Banks and the Agent named therein (the "LLC Credit
Agreement Secured Parties");

                  (e) certified copies of the Certificate of Incorporation and
By-Laws of HGC;

                  (f) a certified copy of certain resolutions of the Board of
Directors of HGC adopted on May 17, 1996;

                  (g) certificates from public officials in the State of
Delaware and in the State of New York as to the good standing of HGC in each
such jurisdiction;

                  (h) unfiled, but signed copies of financing statements naming
Hudson General Corporation, as debtor, and The First National Bank of Boston, as
Collateral Agent, as secured party, which I understand will be filed within ten
(10) days of the transfer of the security interest recited therein in the
offices of the Secretary of State of the State of New York and Nassau County,
New York (such filing offices, the "Filing Offices" and such financing
statements, the "Financing Statements");

                  (i) the Perfection Certificate of HGC (the "Perfection
Certificate"); and

                  (j) such other documents as I have deemed necessary or
appropriate as a basis for the opinions set forth below.

                  In my examination I have assumed the genuineness of all
signatures, including indorsements (other than those on behalf of HGC, with all
of which I am familiar), the legal capacity of natural persons, the authenticity
of all documents submitted to me as originals, the conformity to original
documents of all documents submitted to me as certified, conformed or
photostatic copies, and the authenticity of the originals of such copies. As to
any facts material to this opinion which I did not independently establish or
verify, I have relied upon statements and representations of officers and other
representatives of HGC and others.

                  Unless otherwise indicated, references in this opinion to the
"Relevant UCC" shall mean the Uniform Commercial Code as in effect on the date
hereof in each of the State of New York and the Commonwealth of Massachusetts.
References to the "New York UCC" shall mean the Uniform Commercial Code as in
effect on the date hereof in the State of New York and references to the "Mass.
UCC" shall mean the Uniform Commercial Code as in effect on the date hereof in
the Commonwealth of Massachusetts. The Credit Agreement, the Notes and the
Pledge Agreement shall hereinafter be referred to as the "Loan Documents". The
Banks, the Agent, the Collateral Agent, and the LLC Credit Agreement Secured
Parties shall hereinafter be referred to as the "Secured Parties".

                  I am admitted to the Bar in the State of New York, and I
express no opinion as to the laws of any jurisdiction other than (i) the laws of
the State of New York, (ii) the General Corporation Law of the State of
Delaware, (iii) the federal laws of the United States of America, other than
such federal laws which relate to the creation and perfection of security
interests or the assignment of rights, including, without limitation, the
Federal Assignment of Claims Act of 1940, as amended and (iv) the Mass. UCC to
the extent necessary to express the opinions set forth in paragraphs 7 and 8
hereof. Each of the Loan Documents provides that it is governed by, and to be
construed in accordance with, the laws of the Commonwealth of Massachusetts. For
purposes of my opinion with respect to the laws of the Commonwealth of
Massachusetts, I have assumed with your consent and without any inquiry that the
applicable laws of the Commonwealth of Massachusetts are the same as those of
the State of New York.

                  My opinions are also subject to the following qualifications:

                  (a) I have assumed that the Credit Agreement and the Pledge
Agreement have been duly authorized, executed and delivered by the applicable
Secured Parties and are enforceable against such parties in accordance with
their respective terms;

                  (b) enforcement of the Loan Documents may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting creditors' rights generally and by general principles of equity
(regardless of whether enforcement is sought in equity or at law);

                  (c) certain of the remedial provisions contained in the Pledge
Agreement, including waivers, with respect to the exercise of remedies against
the collateral may be unenforceable in whole or in part, but the inclusion of
such provisions does not affect the validity of the Pledge Agreement, and the
Pledge Agreement taken as a whole, together with applicable law, contains
adequate provisions for the practical realization of the benefits of the
security created thereby; and

                  (d) I express no opinion as to the effect on the opinions
expressed herein of (i) the compliance or non-compliance of any party (other
than HGC) to the Loan Documents with any state, federal or other laws or
regulations applicable to any of them, (ii) the legal or regulatory status or
the nature of the business of any of the Secured Parties, (iii) the sale or
other disposition by any of the Secured Parties of all or any portion of any
securities pledged by HGC (which will require compliance with applicable federal
and state securities laws), or (iv) any fraudulent transfer or similar laws.

                  Based upon the foregoing and subject to the limitations,
qualifications, exceptions and assumptions set forth herein, I am of the opinion
that:

                           1. HGC is a corporation which has been duly
incorporated and is subsisting and in good standing under the laws of the State
of Delaware, and has all requisite 
   76
The First National Bank of Boston
European American Bank
The Chase Manhattan Bank, N.A.
June 1, 1996
Page 4


corporate power to own its property and conduct its business as now conducted
and as presently contemplated.

                           2. To the best of my knowledge, HGC is duly qualified
and in good standing as a foreign corporation and is duly authorized to do
business in each jurisdiction where the nature of its properties or its business
requires such qualification except for the State of Alabama.

                           3. The execution and delivery by HGC of the Loan
Documents, and the performance by HGC of its obligations under the Loan
Documents, are within the corporate authority of HGC, have been duly authorized
by proper corporate proceedings, will not contravene any provision of HGC's
Certificate of Incorporation or By-Laws, or contravene any provision of, or
result in the creation of any mortgage, lien, pledge, charge, security interest
or other encumbrance upon any of the property of HGC (other than liens created
under or permitted by the terms of the Loan Documents) under, any other
agreement, instrument or undertaking binding upon HGC or any property of HGC,
and do not conflict with or result in any breach or contravention of any
provision of any law, statute, rule or regulation to which HGC is subject or any
judgment, order, writ, injunction, license or permit applicable to HGC. HGC has
duly executed and delivered each of the Loan Documents.

                           4. Each of the Loan Documents constitutes the valid
and legally binding obligation of HGC, enforceable against HGC in accordance
with its terms. With respect to the foregoing, I express no opinion, however, as
to rights to indemnification and rights of contribution provided for in any of
the Loan Documents to the extent such rights are violative of federal or state
securities laws, rules or regulations or public policy.

                           5. To the best of my knowledge, except as described
in Schedule 3.8 to the Credit Agreement, there is no litigation pending or
threatened against HGC before any court, tribunal or administrative agency or
board which is of a substantial amount and which, if adversely determined, might
reasonably be expected to materially adversely affect the ability of HGC to
perform its obligations under the Loan Documents, or in respect of the Revolving
Credit Loans, after taking into account any applicable insurance coverage.

                           6. The execution and delivery by HGC of each of the
Loan Documents and the performance by HGC of its obligations under each of the
Loan Documents, each in accordance with its terms, do not require any approval
or consent of, or filing with, any governmental or other agency or authority
except for (a) approvals, consents and filings specified in the Loan Documents
and (b) those already obtained or made. Notwithstanding the foregoing, except as
expressly set forth in paragraphs 7 and 8 hereof, I express no opinion as to the
validity, perfection or priority of any security interest created by the Pledge
Agreement.

                           7. I note that the proper legal characterization of
an interest in a limited liability company is a matter not entirely free from
doubt. Accordingly, I express no opinion as 
   77
The First National Bank of Boston
European American Bank
The Chase Manhattan Bank, N.A.
June 1, 1996
Page 5

to the proper characterization of HGC's interest in Hudson LLC. To the extent
that such interest is characterized as a "general intangible" (as defined in
Section 9-106 of the Relevant UCC) then my opinion in this paragraph 7 shall be
applicable. To the extent that such interest is characterized as a "certificated
security" (as defined in Section 8-102 of the Relevant UCC) my opinion in
paragraph 8 shall be applicable.

                  To the extent that HGC's interest in Hudson LLC is
characterized as a "general intangible" (as defined in Section 9-106 of the
Relevant UCC) then the provisions of the Pledge Agreement are effective to
create, in favor of the Collateral Agent for the benefit of the Secured Parties
to secure the Obligations (as defined in the Pledge Agreement), a valid security
interest under the Mass. UCC in HGC's rights in Class A units (the "Pledged
Units") of Hudson LLC identified in Schedule I hereto (the "Intangible
Collateral"). The Financing Statements are in appropriate form for filing in
each of the Filing Offices under the New York UCC. The security interest in
favor of the Collateral Agent for the benefit of the Secured Parties the
Intangible Collateral which is described in the Financing Statements will be
perfected upon the filing of the Financing Statements in the respective Filing
Offices.

                  My opinion in paragraph 7 with respect to the security
interest of the Collateral Agent for the benefit of the Secured Parties in the
Pledged Units is subject to the following qualifications:

                  (a) The security interest opinions are limited to Article 9 of
the Relevant UCC, and therefore such opinions do not address (i) laws of
jurisdictions other than the State of New York or the Commonwealth of
Massachusetts, and of the State of New York and the Commonwealth of
Massachusetts except for Article 9 of the Relevant UCC, (ii) collateral of a
type not subject to Article 9 of the Relevant UCC, and (iii) under Section 9-103
of the Relevant UCC, what law governs perfection of the security interests
granted in the collateral covered by this opinion. In addition, as noted above,
I have assumed without any inquiry that the Mass. UCC is identical in all
respects to the New York UCC;

                  (b) I call to your attention that under the Relevant UCC,
events occurring subsequent to the date hereof may affect any security interest
subject to the Relevant UCC including, but not limited to, factors of the type
identified in Section 9-306 with respect to proceeds; Section 9-402 with respect
to changes in name, structure and corporate identity of the debtor; Section 
9-103 with respect to changes in the location of the collateral and the location
of the debtor; Section 9-316 with respect to subordination agreements; Section 
9-403 with respect to continuation statements; and Sections 9-307, 9-308 and
9-309 with respect to subsequent purchasers of the collateral. In addition,
actions taken by a secured party (e.g., releasing or assigning the security
interest, delivering possession of the collateral to the debtor or another
person and voluntarily subordinating a security interest) may affect the
validity, perfection or priority of a security interest;

                  (c) I express no opinion with respect to the priority of the
security interest of the Collateral Agent for the benefit of the Secured Parties
in any of the Pledged Units; and

                  (d) I call to your attention that becoming a member of Hudson
LLC may require compliance with the terms of the Limited Liability Company
Agreement, dated as of June 1, 1996 (the "LLC Agreement") among HGC, Hudson LLC
and the other parties named therein, or other action.

                      8. To the extent that HGC's interest in Hudson LLC is
characterized as a "certificated security" (as defined in Section 8-102 of the
Relevant UCC), the delivery to the Collateral Agent for the benefit of the
Secured Parties in the Commonwealth of Massachusetts of the certificates for the
Class A units of Hudson LLC identified in Schedule I hereto, together with the
Pledge Agreement, is effective under the Mass. UCC to create in favor of the
Collateral Agent for the benefit of the Secured Parties, a valid and perfected
security interest in the Pledged Units to secure the Obligations (as defined in
the Pledge Agreement). Under the Mass. UCC, no interest of any other creditor of
HGC is equal or prior to the security interest of the Collateral Agent for the
benefit of the Secured Parties in the Pledged Units.

                  My opinion in paragraph 8 with respect to the security
interest of the Collateral Agent for the benefit of the Secured Parties in the
Pledged Units is subject to the following qualifications:

                  (a) The security interest opinions are limited to Article 8 of
the Mass. UCC, and therefore such opinions do not address (i) laws of
jurisdictions other than the Commonwealth of Massachusetts, and of the
Commonwealth of Massachusetts except for Article 8 of the Mass. UCC, (ii)
collateral of a type not subject to Article 8 of the Mass. UCC, and (iii) under
Section 9-103 of the Mass. UCC, what law governs perfection of the security
interests granted in the collateral covered by this opinion. In addition, as
noted above, I have assumed without any inquiry that the Mass. UCC is identical
in all respects to the New York UCC;

                  (b) I call to your attention that under the Mass. UCC, events
occurring subsequent to the date hereof may affect any security interest subject
to the Mass. UCC including, but not limited to, factors of the type identified
in Section 9-306 with respect to proceeds; Section 9-402 with respect to changes
in name, structure and corporate identity of the debtor; Section 9-103 with
respect to changes in the location of the collateral and the location of the
debtor; Section 9-316 with respect to subordination agreements; Section 9-403
with respect to continuation statements; and Sections 9-307, 9-308 and 9-309
with respect to subsequent purchasers of the collateral. In addition, actions
taken by a secured party (e.g., releasing or assigning the security interest,
delivering possession of the collateral to the debtor or another person and
voluntarily subordinating a security interest) may affect the validity,
perfection or priority of a security interest;

                  (c) I express no opinion with respect to proceeds of, or
distributions on the Pledged Units;

                  (d) I have assumed that each of the Secured Parties acquired
its interest in the Pledged Units for value and in good faith and that none of
the Secured Parties has notice prior to

or on the later of the date of delivery and the date hereof of an adverse claim
with respect to the Pledged Units;

                  (e) I have assumed that each of the Pledged Units is indorsed
to or registered in the name of the Collateral Agent for the benefit of the
Secured Parties or is indorsed in blank;

                  (f) I express no opinion with respect to the priority of the
security interests of the Collateral Agent for the benefit of the Secured
Parties in the Pledged Units against a lien creditor (as such term is defined in
Section 9-301(3) of the Mass. UCC) with respect to future advances to the extent
set forth in Section 9-301(4) of the Mass. UCC; and

                  (g) I call to your attention that becoming a member of Hudson
LLC may require compliance with the terms of the LLC Agreement or other action.

                           9. Upon the consummation of the transactions
contemplated by the Purchase Agreement, HGC shall be the registered owner of the
Pledged Units.

                           10. The Notes constitute "Superior Indebtedness"
under the Indenture, dated as of July 1, 1986 (the "Indenture") between HGC and
Chemical Bank Delaware, as trustee (the "Trustee") as amended by the First
Supplemental Indenture, dated as of April 22, 1996, among HGC, Hudson LLC and
the Trustee, relating to HGC's 7% Convertible Subordinated Debentures Due 2011
(the "Debentures"). The Notes are entitled to the benefits of the provisions of
such Indenture which subordinate such Debentures to "Superior Indebtedness".

                  This opinion is being furnished only to you and is solely for
your benefit, and is not to be used, circulated, relied upon or otherwise
referred to for any other purpose without my prior written consent provided that
the LLC Credit Agreement Secured Parties on the date hereof may rely on this
opinion on and as of the date hereof.

                                          Very truly yours,

                                  SCHEDULE 3.8

1.       Texaco Canada Inc. (now McColl-Frontenac Inc.) v.
         Petro-Canada Inc., Hudson General Aviation Services Inc.
         and Hudson General Corporation

         In 1988, Texaco Canada Inc. ("Texaco") (now McColl-Frontenac Inc.)
instituted a lawsuit in the Supreme Court of Ontario, Canada against HGC,
Aviation and Petro-Canada Inc., the corporation which supplied aviation fuel for
Aviation's fixed base operations. The suit's allegations, as amended, are that
the defendants interfered with contractual and fiduciary relations, conspired to
injure, and induced the breach of a fuel supply agreement between Texaco and
Innotech Aviation Limited ("Innotech") in connection with the purchase by
Aviation from Innotech in 1984 of certain assets of Innotech's airport ground
services business. The suit seeks compensatory and punitive damages totaling
$110,000,000 (Canadian) plus all profits earned by the defendants subsequent to
the alleged breach. The trial of this suit commenced on May 6, 1996 and is
anticipated to be lengthy. Innotech (which due to a name change is now called
Aerospace Realties (1986) Limited ("Aerospace")) had agreed to defend and
indemnify HGC and Aviation against claims of whatever nature asserted in
connection with, arising out of or resulting from the fuel supply agreement with
Texaco. By a letter dated February 15, 1996, HGC was notified by Aerospace that
Aerospace has entered into a liquidation phase and can no longer defray the cost
of defending this lawsuit or pay for any damages resulting therefrom. HGC's
management believes, and counsel for HGC and Aviation has advised based on
available facts, that HGC and Aviation will successfully defend this action.

2.       Michael and Kerri Balletta, Melody and Jeffrey Gross, James and Bari
         Rodgers v. Russell Worrell, et. al.

         These three lawsuits, which have been consolidated, were commenced in
1991 by the parents of three children and allege that the children were sexually
abused by the driver and matron of a school bus operated by Valley Transit
("Valley") used to transport handicapped children to special schools under
contract with the County of Nassau, N.Y. (the "County"). Besides the driver and
matron, the defendants include Valley, the County, the local school district of
each child and HGC. HGC provides management services to the County with respect
to the County's program to transport handicapped school children, but does not
itself operate the transportation services. The lawsuits seek a total of
$150,000,000 of compensatory and $150,000,000 of punitive damages.

         The alleged intentional torts (which were not committed by HGC) and
punitive damages may not be covered by insurance. In the Management Services
Agreement between HGC and the County, the County has agreed to indemnify HGC,
and to cause the transportation contractor to indemnify HGC, against claims
arising out of or in connection with the conduct or operation of the
transportation services and any acts of the contractor and its employees. The
insurance company for Valley is defending HGC pursuant to an insurance policy
under which HGC is an additional insured.

                                SCHEDULE 3.18(b)



1.       Salt Lake City-County Health Department
         Notice of Violation and Order of Compliance
         HDWQR 21/2-14-91

         This Notice and Order results from a spill on February 13, 1991 of
approximately 4,500 gallons of jet fuel at the Company's fuel farm at Salt Lake
City International Airport. The spill occurred when the driver of an
unaffiliated company's fuel delivery truck overfilled one of the Company's fuel
storage tanks. No fine or other penalty has been assessed against the Company.

         The Company took immediate action to remove surface contamination and
is cooperating with the Salt Lake City Airport authorities in the environmental
investigation to determine the impact of the spill on subsurface soil and ground
water. The Company has also brought a lawsuit against the fuel delivery company
which caused the spill.


2.       Vancouver International Airport Authority

         Aviation is in the process of cleaning up soil contaminated by two
leaking underground waste oil tanks on one of its former leaseholds at Vancouver
International Airport, which tanks were negligently installed by a preceding
leaseholder. Aviation has reserved its rights against this leaseholder.


3.       Massport Environmental Claim

         In April 1994, a law firm representing the Massachusetts Port Authority
("Massport") sent a letter (the "Original Demand") to thirty-seven (37)
companies, including HGC, notifying the addressees that Massport believed that
they were liable for contamination of soil and groundwater at Logan
International Airport in East Boston, Massachusetts (the "Airport"). Massport
claimed that it was performing response actions at the Airport, and stated that
it was seeking "contribution, reimbursement and payment of an equitable share of
the costs of past, current and future response actions undertaken by
Massport...".

         The Original Demand identified twenty-four (24) spills of fuel, oil and
hydraulic fluid at various places at the Airport which allegedly had been caused
by HGC between January 1982 and September 1992. In addition, the Original Demand
proposed a settlement by which HGC would pay a per capita share of past response
costs (such share to be a minimum of $311,761) and agree to pay a per capita
share of all future response costs or undertake to perform all necessary future
response actions at locations where it had releases.

                                SCHEDULE 3.18(B)


         In July 1994, HGC responded to the Original Demand, raising numerous
objections to Massport's allegations and requesting considerable additional
information in Massport's possession.

         Following an informational meeting held by Massport in September 1994
for all parties which had received the Original Demand, Massport sent a letter
dated October 5, 1994 to HGC (the "Massport Proposal") clarifying its position
and proposing a greatly reduced settlement payment. The Massport Proposal first
proposed a cash-out payment by HGC for past response costs of $29,968 in respect
of a reduced total of twenty-two (22) spills. (By contrast, Massport alleged a
grand total of 2,462 spills at the Airport since 1953.) The Massport Proposal
further limited Massport's claim against HGC for future response costs to three
sites where HGC allegedly had a total of only ten (10) spills. The proposed
settlement in respect of these future response costs was $526,154, bringing
Massport's aggregate settlement proposal to $556,122.

         After obtaining additional information from Massport, HGC responded to
the Massport Proposal by letter dated January 20, 1995, reiterating objections
made previously and stating additional objections. However, HGC offered to pay
Massport $75,000 in return for a complete release and a mutually acceptable
settlement agreement that would include indemnification by Massport against any
claims brought against HGC by any other party, including government agencies.

         HGC did not hear further from Massport until it received a letter dated
March 5, 1996 (the "Massport 1996 Letter") in which Massport stated that it had
now identified a grand total of 2,593 spills at the Airport prior to March 9,
1994. The Massport 1996 Letter proposed a revised cash-out payment by HGC for
past response costs of $32,334, and expanded Massport's claim against HGC for
future response costs to a total of twenty-seven (27) spills at five (5) sites.
Massport's proposed settlement in respect of these future response costs totaled
$1,500,347, for an aggregate settlement demand of $1,532,681.

         HGC is considering how it will respond to the new Massport proposal.
