                 This Amendment No. 7 to Schedule 13D relates to the shares of
Common Stock, $.01 par value (the "Shares"), of Phoenix Information Systems
Corp. (the "Issuer") and amends the initial statement on Schedule 13D dated
December 16, 1994 and all prior amendments thereto (collectively, the "Initial
Statement").  This Amendment No. 7 is being filed to report the acquisition of
300,000 additional Shares as a result of the decrease in the conversion price
of the $1,200,000 Tranche D Note (as previously described in Amendment No. 4),
the acquisition of warrants to purchase 140,000 shares pursuant to the August
Letter Agreement as a result of the occurrence of a condition precedent
thereto, the receipt of a warrant to purchase an additional 345,000 Shares as a
result of the acquisition of another Tranche D Note in the amount of $1,150,000
(the "$1,150,000 Tranche D Note"), and the purchase and conversion of the 
$1,150,000 Tranche D Note into 1,150,000 Shares.  Capitalized terms used herein
but not defined herein shall have the meanings assigned to them in the Initial
Statement.  The information set forth in the Initial Statement is amended as
set forth herein.                                                  

ITEM 3.          SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

                 On August 3, 1995, Phoenix Partners and the Issuer entered
into a letter agreement (the "August Letter Agreement"), a copy of which is
attached as Exhibit O to Amendment No. 3 to the Initial Statement, which
modified the Note Purchase Agreement and pursuant to which Phoenix Partners
purchased from the Issuer the remaining $200,000 Tranche C Note and a $150,000
Tranche D Note out of the working capital or personal funds of its partners.
As of February 12, 1996, pursuant to the terms of the August Letter Agreement
and a subsequent agreement executed as of the date thereof (the "Additional
Warrant Agreement"), a copy of which is attached as Exhibit AA hereto, as well
as a letter agreement executed concurrently with the Additional Warrant
Agreement (the "Additional Warrant Letter Agreement") a copy of which is
attached as Exhibit AB hereto, for no additional consideration, Phoenix
Partners received the 140,000 Additional Warrants (as described in the August
Letter Agreement).

                 On September 15, 1995, Phoenix Partners and the Issuer entered
into a letter agreement (the "September Letter Agreement"), a copy of which is
attached as Exhibit S to Amendment No. 4 to the Initial Statement and the terms
of which are more fully described in Item 4 thereto, which modified the Note
Purchase Agreement and certain other agreements related thereto.  Pursuant to
the September Letter Agreement, Phoenix Partners, among other things, purchased
from the Issuer a Tranche D Note in the principal amount of $1,200,000, using
the working capital or personal funds of its partners.  Concurrently therewith,
Phoenix Partners converted the $1,200,000 Tranche D Note into 1,200,000 Shares
at a $1.00 per Share conversion price.  Subsequently, as of February 12, 1996,
the conversion price of the $1,200,000 Tranche D Note decreased to $0.80 per
Share; therefore, for no additional consideration, Phoenix Partners received
300,000 additional Shares pursuant to the terms of the September Letter
Agreement.

                 On February 12, 1996, Phoenix Partners and the Issuer entered
into an agreement (the "February Warrant Agreement"), a copy of which is
attached as Exhibit AC hereto and the terms of which are more fully described
in Item 4 hereof, which modified the Note Purchase Agreement and certain other
agreements related thereto.  Pursuant to the February Warrant Agreement,
Phoenix Partners, among other things, purchased from the Issuer the $1,150,000
Tranche D Note, using the working capital or personal funds of its partners.
Concurrently therewith, Phoenix Partners converted the $1,150,000 Tranche D
Note for 1,150,000 Shares at a $1.00 per Share conversion price.  In addition,
pursuant to the February Warrant Agreement, on February 12, 1996, Phoenix
Partners and the Issuer entered into a letter agreement (the "February Letter
Agreement"), a copy of which is attached as Exhibit AD hereto and the terms of
which are more fully described in Item 4 hereof, whereby Phoenix Partners
received

a warrant to purchase an additional 345,000 Shares, for no additional
consideration, in exchange for the acquisition of the $1,150,000 Tranche D
Note.

ITEM 4.          PURPOSE OF TRANSACTION.

                 Phoenix Partners entered into the August Letter Agreement and
the September Letter Agreement for investment purposes and pursuant to the
terms of the Note Purchase Agreement.  The August Letter Agreement provided
that if the System had not been installed in China in connection with an
airline of comparable size to Hainan Airlines and/or the System was not
operational within 90 days of August 3, 1995, the Issuer would issue to Phoenix
Partners Additional Warrants to purchase 140,000 Shares at an exercise price of
(i) 0.85 multiplied by (ii) the lowest average weekly closing price of the
Shares during the ninety day period commencing on August 3, 1995.  This
provision in the August Letter Agreement was subsequently modified in the
September Letter Agreement whereby the Additional Warrants would only be issued
if the System had not been installed in China in connection with an airline of
comparable size to Hainan Airlines and/or the System was not operational on or
before January 15, 1996.  On February 12, 1996, Phoenix Partners and the Issuer
agreed that this condition had not been met in full by January 15, 1996;
therefore, pursuant to the terms of the Additional Warrant Agreement and the
Additional Warrant Letter Agreement, Phoenix Partners received the 140,000 
Additional Warrants exercisable at a price of $3.23 per Share.

                 As of September 15, 1995, Phoenix Partners and the Issuer
entered into the September Letter Agreement.  Pursuant to the September Letter
Agreement, Phoenix Partners purchased a Tranche D Note in the principal amount
of $1,200,000 and converted such $1,200,000 Tranche D Note into 1,200,000
Shares.  A copy of the form of the $1,200,000 Tranche D Note is attached as 
Exhibit T to Amendment No. 4 to the Initial Statement.  The $1,200,000 Tranche 
D Note was converted into 1,200,000 Shares at a conversion price of $1.00 per 
Share. However, the Issuer agreed that should it fail to meet certain 
operational targets by January 15, 1996, the conversion price would be adjusted
so that the conversion will have been deemed to have occurred at a lower price,
with an absolute minimum conversion price of $0.60 per Share. Upon any deemed 
change in the conversion price in the $1,200,000 Tranche D Note purchased and 
converted on September 15, 1995, the Issuer would issue to Phoenix Partners 
certificates representing such additional Shares.  As of January 15, 1996, the 
parties had not agreed as to whether the operational targets were met in full. 
On February 12, 1996, the parties agreed operational targets were not met in 
full by January 15, 1996; therefore, Phoenix Partners and the Issuer entered 
into the Additional Warrant Letter Agreement pursuant to which the conversion 
price of the $1,200,000 Tranche D Note decreased to $0.80 and thus, as of 
February 12, 1996, Phoenix Partners received an additional 300,000 Shares.

                 As of February 12, 1996, Phoenix Partners and the Issuer
entered into the February Warrant Agreement.  Pursuant to the February Warrant
Agreement, Phoenix Partners purchased the $1,150,000 Tranche D Note and
converted the $1,150,000 Tranche D Note into 1,150,000 Shares.  A copy of the
form of the $1,150,000 Tranche D Note is attached as Exhibit AE hereto.  The
$1,150,000 Tranche D Note was converted into Shares at a conversion price of
$1.00 per Share, resulting in the receipt by Phoenix Partners of 1,150,000
Shares.  However, pursuant to the terms of the February Letter Agreement, the
Issuer agreed that in the event the System is not Fully Operational (as defined
in the February Letter Agreement) on or before each of the dates stated
therein, the Conversion Price (as defined in the February Warrant Agreement)
shall be adjusted according to the amounts set forth in the terms of the
$1,150,000 Tranche D Note so that the conversion will have deemed to have
occurred at the lower price.  Upon any deemed change in the conversion price in
the $1,150,000 Tranche D Note purchased and converted on February 12, 1996, the
Issuer will issue to Phoenix Partners certificates representing such additional
Shares.  In consideration of the acquisition of the $1,150,000 Tranche D

Note, Phoenix Partners received from the Issuer a warrant to purchase 345,000
Shares for a purchase price of $3.00 per share.

                 (a)      The aggregate number of Shares of which each of the

                 2.       Issue of Warrants.  The Warrant Certificates shall be
in registered form only and substantially in the form attached hereto as
Exhibit A, shall be dated the date on which signed by an authorized signatory
of the Company and may have such legends and endorsements typed, stamped or
printed thereon as the Company may deem appropriate and as are not inconsistent

Incorporation, then the Warrants shall be deemed to have been exercised.

                                  (3)      Method of Exercise; Payment of
Exercise Price.  In order to exercise any or all of the Warrants represented by
a Warrant Certificate, the Holder must surrender the Warrant Certificate to the
Company for exercise, with the reverse side of the Warrant Certificate duly
executed, together with any required payment in full of the Exercise Price for
each share of Underlying Common Stock to which the Holder is entitled, any such
payment of the Exercise Price to be made by check or wire transfer to an
account designated by the Company.  If the Holder elects to exercise only a
portion of the Warrants represented by the Warrant Certificate or Certificates
registered in its name, then the remaining portion of the Warrants shall be
returned to the Holder in the form of a new Warrant Certificate.  Upon
surrender of a Warrant Certificate and the payment of the Exercise Price in
conformity with the foregoing provisions, the Company shall promptly issue to
the Holder share certificates representing the Underlying Common Stock to which
the Holder is entitled, registered in the name of the Holder or the name or
names of such Affiliates of the Holder as may be directed in writing by the
Holder, and shall deliver such share certificates to the Person or Persons
entitled to receive the same.  The Company shall issue such share certificates
within five Business Days after the payment of the Exercise Price of the
Warrants by the Holder, but such shares shall be deemed issued and outstanding
on the date the Warrant is exercised and the Exercise Price is paid to the
Company.

                          (c)     Exercise by Surrender of Warrant; Exercise
with Shares of Common Stock.  In addition to the method of exercise set forth
in Section 3(b)(3) above and in lieu of any cash payment required thereunder,
the Holder shall have the right at any time and from time to time to exercise
the Warrants in full or in part (i) by surrendering its Warrant Certificate in
the manner specified in Section 3(b)(3) in exchange for the number of shares of
Common Stock equal to the product of (x) the number of shares as to which the
Warrants are being exercised multiplied by (y) a fraction, the numerator of
which is the Market Price (as defined hereafter) of the Common Stock less the
Exercise Price and the denominator of which is such Market Price, or (ii) by
surrendering the Warrant Certificate in the manner specified in Section 3(b)(3)
above and making any required payment in whole or in part of the Exercise Price
for each share of Underlying Common Stock to which the Holder is entitled with
shares of Common Stock (valued at the Market Price).  As used herein, "Market
Price" shall mean the average of the closing prices of the Common Stock sales
on all domestic exchanges on which the Common Stock may at the time be listed,
or, if there shall have been no sales on any such exchange on any day, the
average of the highest bid and lowest asked prices on all such exchanges at the
end of such day, or, if on any day the Common Stock shall not be so listed, the
average of the representative bid and asked prices quoted in the NASDAQ System
as of 3:30 p.m. New York City time, or if on any day the Common Stock shall not
be quoted in the NASDAQ System, the average of the high and low

bid and asked prices on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporation or any similar
successor organization, in each such case averaged over a period of 30
consecutive Business Days immediately prior to the date of exercise; provided
that if the Common Stock is listed on any domestic exchange the term "Business
Days" as used in this sentence shall mean business days on which such exchange
is open for trading.  If at any time the Common Stock is not listed on any
domestic exchange or quoted in the NASDAQ System or the domestic
over-the-counter market, the Market Price shall be deemed to be the fair market
value thereof as of the date of exercise, determined by an independent
appraiser selected by the Company and acceptable to the Holder.

                 4.       Adjustments.  The Exercise Price shall be subject to
adjustment as follows:

                          (a)     In the event the Company shall issue
additional shares of Common Stock (or securities convertible into or
exchangeable for Common Stock) in a stock dividend, stock distribution or
subdivision paid with respect to Common Stock, or declare any dividend or other
distribution payable with additional shares of Common Stock (or securities
convertible into or exchangeable for Common Stock) with respect to Common Stock
or effect a split or subdivision of the outstanding shares of Common Stock, the
Exercise Price shall, concurrently with the effectiveness of such stock
dividend, stock distribution or subdivision, or the earlier declaration
thereof, be proportionately decreased, and the number of Underlying Common

                                                             PAGE 26 OF 76 PAGES

Stock shall be proportionately adjusted so that, to avoid dilution of the
Holder's position, the Holder shall thereafter be entitled to receive at such
adjusted price an additional number of shares of the Company's Common Stock
which such Holder would have owned or would have been entitled to receive upon
or by reason of any of the events described above, had the Warrants been
exercised immediately prior to the happening of such event.

                          (b)     In the event the outstanding shares of Common
Stock shall be combined or consolidated, by reclassification or otherwise, into
a lesser number of shares of Common Stock, the Exercise Price shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately increased and the number of Underlying Common Stock shall be
proportionately adjusted so that the Holder of any Warrant exercised after such
date shall be entitled to receive, upon payment of the same aggregate amount as
would have been payable before such date, the aggregate number of shares of
Common Stock which the Holder would have owned upon such exercise and been
entitled to receive, if such Warrant had been exercised immediately prior to
the happening of such combination or consolidation.

                          (c)     In the event of any consolidation or merger
of the Company with or into another corporation or the conveyance of all or
substantially all of the assets of the Company to another corporation or
entity, the Warrants shall thereafter be exercisable for the number of shares
of capital stock or other securities or property to which a holder of the
number of shares of Common Stock deliverable upon conversion hereof would have

                                                             PAGE 27 OF 76 PAGES

been entitled upon such consolidation, merger or conveyance; and, in any such
case, appropriate adjustment shall be made in the application of the provisions
herein set forth with respect to the rights and interests of the Holder
thereafter, to the end that the provisions set forth herein (including
provisions with respect to adjustments in the Exercise Price) shall thereafter
be applicable, as nearly as may be practicable, in relation to any shares of
stock or other property thereafter deliverable upon the exercise of Warrants.
At the request of the Holder, the resulting or surviving entity in any such
consolidation or merger, if other than the Company, shall acknowledge in
writing the Holder's rights hereunder.

                  5.      Loss or Mutilation.  Upon receipt by the Company of
evidence satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of any Warrant Certificate and of indemnity
satisfactory to it, and (in the case of mutilation) upon surrender and
cancellation thereof, then, in the absence of notice to the Company that the
Warrants represented thereby have been acquired by a bona fide purchaser, the
Company shall deliver to the Holder, in exchange for or in lieu of the lost,
stolen, destroyed or mutilated Warrant Certificate, a new Warrant Certificate
of the same tenor and for a like aggregate number of Warrants. Upon the

or not the allegedly lost, stolen or destroyed Warrant Certificate shall be at
any time enforceable by anyone, and shall be entitled to the benefit of this
Additional Warrant Agreement equally and proportionately with any and all other
Warrant Certificates duly executed and delivered hereunder.  The provisions of

outstanding Warrants.

                 7.       Limitations on Transfer; Warrant Transfer Books.  The
Warrants may be sold, transferred, pledged, assigned, hypothecated or otherwise

prescribe, the Company shall provide the registration of Warrant Certificates
and transfers or exchanges of Warrant Certificates as herein provided.

                 The Holder of a Warrant Certificate, by its acceptance
thereof, covenants and agrees that the Warrants are being acquired, and the
Underlying Common Stock to be purchased upon the exercise of this Warrant will
be acquired, as an investment and not with a view to the distribution thereof
and will not be sold or transferred except in accordance with the applicable
provisions of the Securities Act of 1933, as amended (the "Act") and the rules
and regulations promulgated thereunder, and that neither this Warrant nor any
of the Underlying Common Stock may be offered or sold except (i) pursuant to an
effective registration statement under the Act, (ii) to the extent applicable,
pursuant to Rule 144 under the Act (or any similar rule under the Act relating
to the disposition of securities), or (iii) pursuant to an exemption from
registration under the Act.

                 The Warrant Certificates and, upon exercise of the Warrants,
in part or in whole, certificates representing the Underlying Common Stock
shall bear a legend substantially similar to the following:

                 "The securities represented by this certificate have not been
                 registered under the Securities Act of 1933, as amended (the
                 "Act"), and may not be offered or sold except (i) pursuant to
                 an effective registration statement under the Act, (ii) to the
                 extent applicable, pursuant to Rule 144 under the Act (or any
                 similar rule under the Act relating to the disposition of
                 securities), or (iii) pursuant to an exemption from
                 registration under the Act."

                 At the option of the Holder, Warrant Certificates may be
exchanged at such office upon payment of the charges

hereinafter provided.  Whenever any Warrant Certificates are so surrendered for
exchange, the Company shall execute and deliver the Warrant Certificates that
the Holder is entitled to receive.  All Warrant Certificates issued upon any
registration of transfer or exchange of Warrant Certificates shall be the valid
obligations of the Company, evidencing the same obligations, and entitled to
the same benefits under this Additional Warrant Agreement, as the Warrant
Certificates surrendered for such registration of transfer or exchange.

                 Every Warrant Certificate surrendered for registration of
transfer or exchange shall (if so required by the Company) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company duly executed by the Holder.  No service charge shall be made for any
registration of transfer or exchange of Warrant Certificates.  The Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer of
Warrant Certificates.

                 8.       No Voting or Dividend Rights.  Prior to the exercise
of the Warrants, the Holder, as a Holder of Warrant Certificates, shall not be
entitled to any rights of a shareholder of the Company, including, without
limitation, the right to vote, to receive dividends or other distributions or
to exercise any preemptive right, but each Holder of Warrant Certificates shall
receive all notices sent to shareholders of the Company, including any notice
of meetings of shareholders, and shall have the right to attend or observe such
meetings.

the United States District Court for the Southern District of New York and of
any New York State court sitting in New York City for purposes of all legal
proceedings arising out of or relating to this Additional Warrant Agreement and
the transactions contemplated hereby.  The Company and the Holder irrevocably
waive, to the fullest extent permitted by law, any objection which they may now

been brought in an inconvenient forum.

                 11.      Successors and Assigns.  The provisions of this
Additional Warrant Agreement shall inure to the benefit of and be binding upon

                                                               February 12, 1996


S-C Phoenix Partners
888 Seventh Avenue
New York, New York 10106


                               Additional Warrant


Gentlemen:

                 Reference is made to the Convertible Note Purchase Agreement
(as amended, "Agreement") dated December 9, 1994 between the undersigned
("Company") and you ("S-C Partners"), as most recently amended by letter
agreement dated September 15, 1995 ("September Letter").  Capitalized terms are
used herein as defined in the Agreement and September Letter.  Pursuant to the
September Letter, the Company agreed to issue to S-C Partners Additional
Warrants, and to adjust the Conversion Price of the Tranche D Note converted
pursuant to the September Letter, in the event that a certain event or events
did not occur by January 15, 1996.

                 The parties wish to modify the September Letter as follows:

                 1.       The Company will issue the Additional Warrants, the
exercise price for which shall be $3.23 per share, pursuant to the Warrant
Agreement annexed hereto as Exhibit A.

                 2.       The Conversion Price for the Tranche D Note issued
and converted pursuant to the September Letter shall be deemed to have been
$.80 per share and the Company shall issue an additional 300,000 shares
("Adjusted Conversion Shares") to S-C Partners to reflect such adjustment.

                 3.       S-C Partners hereby represents and warrants as
follows:

                          (a)     The Adjusted Conversion Shares and the
                 Additional Warrants ("Securities") being acquired by S-C
                 Partners are being acquired for investment for its own account
                 and not with the view to, or for resale in connection with,
                 any distribution or public offering thereof.  S-C Partners
                 understands that such Securities have not been registered under
                 the Securities Act of 1933, as amended (the "Securities Act")
                 or any state securities laws by reason of their contemplated
                 issu-

                 ance in transactions exempt from the registration requirements
                 of the Securities Act pursuant to Section 4(2) thereof and
                 applicable state securities laws, and that the reliance of the
                 Company and others upon these exemptions is predicated in part
                 upon this representation by S-C Partners. S-C Partners further
                 understands that such Securities may not be transferred or
                 resold without (i) registration under the Securities Act and
                 any applicable state securities laws, or (ii) an exemption from
                 the requirements of the Securities Act and applicable state
                 securities laws.

                          (b)     S-C Partners understands that an exemption
                 from such registration is not presently available pursuant to
                 Rule 144 promulgated under the Securities Act by the
                 Securities and Exchange Commission (the "Commission") and
                 that, in any event, S-C Partners may not sell any such
                 Securities pursuant to Rule 144 prior to the expiration of a
                 two-year period after it has acquired such Securities.  S-C
                 Partners understands that any sales pursuant to Rule 144 can
                 be made only in full compliance with the provisions of Rule
                 144.

                          (c)     The address of S-C Partner's principal office
                 is set forth on its Certificate of Representations dated the
                 date hereof.  S-C Partners qualifies as an "accredited
                 investor" for purposes of Regulation D promulgated under the
                 Securities Act for the reasons specified in such Certificate
                 of Representations.  S-C Partners acknowledges that the
                 Company has made available to it at a reasonable time prior to
                 the execution of the Certificate of Representations the
                 opportunity to ask questions and receive answers concerning
                 the terms and conditions of the sale of securities
                 contemplated by the Agreement, and to obtain any additional
                 information (which the Company possesses or can acquire
                 without unreasonable effort or expense) as may be necessary to
                 verify the accuracy of the information furnished to it.  S-C
                 Partners (i) is able to bear of loss of its entire investment
                 in the Securities being acquired by it without any material
                 adverse effect on its business, operations or prospects, and
                 (ii) has such knowledge and experience in financial and
                 business matters that it is capable of evaluating the merits
                 and risks of the investment to be made by it pursuant to the
                 Agreement and pursuant hereto.

                          4.      Except as modified hereby, the Agreement
remains in full force and effect.

                          5.      This Agreement (a) represents the entire
agreement among the parties with respect to the subject matter hereof,
superseding all prior agreements and understandings, written or oral, (b) may
be amended only in writing, (c) may be executed in counterparts, each of which
shall be deemed an original and all of which shall constitute one agreement,

inure to the benefit of, and be binding upon, the parties hereto and their
respective successors and assigns and (e) shall be governed by and construed in

                    (3)  Method of Exercise; Payment of Exercise Price. In order
to exercise any or all of the Warrants represented by a Warrant Certificate, the
Holder must surrender the Warrant Certificate to the Company for exercise, with
the reverse side of the Warrant Certificate duly executed, together with any
required payment in full of the Exercise Price for each share of Underlying
Common Stock to which the Holder is entitled, any such payment of the Exercise
Price to be made by check or wire transfer to an account designated by the
Company. If the Holder elects to exercise only a portion of the Warrants
represented by the Warrant Certificate or Certificates registered in its name,
then the remaining portion of the Warrants shall be returned to the Holder in
the form of a new Warrant Certificate. Upon surrender of a Warrant Certificate
and the payment of the Exercise Price in conformity with the foregoing
provisions, the Company shall promptly issue to the Holder share certificates
representing the Underlying Common Stock to which the Holder is entitled,
registered in the name of the Holder or the name or names of such Affiliates of
the Holder as may be directed in writing by the Holder, and shall deliver such
share certificates to the Person or Persons entitled to receive the same. The
Company shall issue such share certificates within five Business Days after the
payment of the Exercise Price of the Warrants by the Holder, but such shares
shall be deemed issued and outstanding on the date the Warrant is exercised and
the Exercise Price is paid to the Company.

                         (c)  Exercise by Surrender of Warrant; Exercise with
Shares of Common Stock. In addition to the method of exercise set forth in
Section 3(b)(3) above and in lieu of any cash payment required thereunder, the
Holder shall have the right at any time and from time to time to exercise the
Warrants in full or in part (i) by surrendering its Warrant Certificate in the
manner specified in Section 3(b)(3) in exchange for the number of shares of
Common Stock equal to the product of (x) the number of shares as to which the
Warrants are being exercised multiplied by (y) a fraction, the numerator of
which is the Market Price (as defined hereafter) of the Common Stock less the
Exercise Price and the denominator of which is such Market Price, or (ii) by
surrendering the Warrant Certificate in the manner specified in Section 3(b)(3)
above and making any required payment in whole or in part of the Exercise Price
for each share of Underlying Common Stock to which the Holder is entitled with
shares of Common Stock (valued at the Market Price). As used herein, "Market
Price" shall mean the average of the closing prices of the Common Stock sales on
all domestic exchanges on which the Common Stock may at the time be listed, or,
if there shall have been no sales on any such exchange on any day, the average
of the highest bid and lowest asked prices on all such exchanges at the end of
such day, or, if on any day the Common Stock shall not be so listed, the average
of the representative bid and asked prices quoted in the NASDAQ System as of
3:30 p.m. New York City time, or if on any day the Common Stock shall not be
quoted in the NASDAQ System, the average of the high and low

                                                            PAGE 51 OF 76 PAGES

bid and asked prices on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporation or any similar
successor organization, in each such case averaged over a period of 30
consecutive Business Days immediately prior to the date of exercise; provided
that if the Common Stock is listed on any domestic exchange the term "Business
Days" as used in this sentence shall mean business days on which such exchange
is open for trading. If at any time the Common Stock is not listed on any
domestic exchange or quoted in the NASDAQ System or the domestic
over-the-counter market, the Market Price shall be deemed to be the fair market
value thereof as of the date of exercise, determined by an independent appraiser
selected by the Company and acceptable to the Holder.

          4.   Adjustments. The Exercise Price shall be subject to adjustment as
follows:

               (a)  In the event the Company shall issue additional shares of
Common Stock (or securities convertible into or exchangeable for Common Stock)
in a stock dividend, stock distribution or subdivision paid with respect to
Common Stock, or declare any dividend or other distribution payable with
additional shares of Common Stock (or securities convertible into or
exchangeable for Common Stock) with respect to Common Stock or effect a split or
subdivision of the outstanding shares of Common Stock, the Exercise Price shall,
concurrently with the effectiveness of such stock dividend, stock distribution
or subdivision, or the earlier declaration thereof, be proportionately
decreased, and the number of Underlying Common


                                        
<PAGE>   8
                                                            PAGE 52 OF 76 PAGES

Stock shall be proportionately adjusted so that, to avoid dilution of the
Holder's position, the Holder shall thereafter be entitled to receive at such
adjusted price an additional number of shares of the Company's Common Stock
which such Holder would have owned or would have been entitled to receive upon
or by reason of any of the events described above, had the Warrants been
exercised immediately prior to the happening of such event.

               (b)  In the event the outstanding shares of Common Stock shall be
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares of Common Stock, the Exercise Price shall, concurrently with the
effectiveness of such combination or consolidation, be proportionately increased
and the number of Underlying Common Stock shall be proportionately adjusted so
that the Holder of any Warrant exercised after such date shall be entitled to
receive, upon payment of the same aggregate amount as would have been payable
before such date, the aggregate number of shares of Common Stock which the
Holder would have owned upon such exercise and been entitled to receive, if such
Warrant had been exercised immediately prior to the happening of such
combination or consolidation.

               (c)  In the event of any consolidation or merger of the Company
with or into another corporation or the conveyance of all or substantially all
of the assets of the Company to another corporation or entity, the Warrants
shall thereafter be exercisable for the number of shares of capital stock or
other securities or property to which a holder of the number of shares of Common
Stock deliverable upon conversion hereof would have

been entitled upon such consolidation, merger or conveyance; and, in any such
case, appropriate adjustment shall be made in the application of the provisions
herein set forth with respect to the rights and interests of the Holder
thereafter, to the end that the provisions set forth herein (including
provisions with respect to adjustments in the Exercise Price) shall thereafter
be applicable, as nearly as may be practicable, in relation to any shares of
stock or other property thereafter deliverable upon the exercise of Warrants. At
the request of the Holder, the resulting or surviving entity in any such
consolidation or merger, if other than the Company, shall acknowledge in writing
the Holder's rights hereunder.

          5.   Loss or Mutilation. Upon receipt by the Company of evidence
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of any Warrant Certificate and of indemnity satisfactory to it, and
(in the case of mutilation) upon surrender and cancellation thereof, then, in
the absence of notice to the Company that the Warrants represented thereby have
been acquired by a bona fide purchaser, the Company shall deliver to the Holder,
in exchange for or in lieu of the lost, stolen, destroyed or mutilated Warrant
Certificate, a new Warrant Certificate of the same tenor and for a like
aggregate number of Warrants. Upon the issuance of any new Warrant Certificate
under this Section 5, the Company may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and other expenses in connection herewith. Every new Warrant Certificate
executed and delivered

                                                            PAGE 54 OF 76 PAGES

pursuant to this Section 5 in lieu of any lost, stolen or destroyed Warrant
Certificate shall constitute a contractual obligation of the Company, whether or
not the allegedly lost, stolen or destroyed Warrant Certificate shall be at any
time enforceable by anyone, and shall be entitled to the benefit of this
Agreement equally and proportionately with any and all other Warrant
Certificates duly executed and delivered hereunder. The provisions of this
Section 5 are exclusive and shall preclude (to the extent lawful) all other
rights or remedies with respect to the replacement of mutilated, lost, stolen,
or destroyed Warrant Certificates.

          6.   Reservation and Authorization of Common Stock. The Company shall,
at all times until the Warrants have been exercised or have expired, reserve and
keep available for issue upon the exercise of Warrants such number of its
authorized but unissued shares of Common Stock as is sufficient for the purpose
of permitting the exercise in full of all outstanding Warrants.

          7.   Limitations on Transfer; Warrant Transfer Books. The Warrants may
be sold, transferred, pledged, assigned, hypothecated or otherwise disposed of
(collectively, "transferred") only to Affiliates of the Holder. The Company
shall cause to be kept at the principal executive office of the Company a
register in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide the registration of Warrant Certificates and transfers
or exchanges of Warrant Certificates as herein provided.

          The Holder of a Warrant Certificate, by its acceptance thereof,
covenants and agrees that the Warrants are being acquired, and the Underlying
Common Stock to be purchased upon the exercise of this Warrant will be acquired,
as an investment and not with a view to the distribution thereof and will not be
sold or transferred except in accordance with the applicable provisions of the
Securities Act of 1933, as amended (the "Act") and the rules and regulations
promulgated thereunder, and that neither this Warrant nor any of the Underlying
Common Stock may be offered or sold except (i) pursuant to an effective
registration statement under the Act, (ii) to the extent applicable, pursuant to
Rule 144 under the Act (or any similar rule under the Act relating to the
disposition of securities), or (iii) pursuant to an exemption from registration
under the Act.

          The Warrant Certificates and, upon exercise of the Warrants, in part
or in whole, certificates representing the Underlying Common Stock shall bear a
legend substantially similar to the following:

          "The securities represented by this certificate have not
          been registered under the Securities Act of 1933, as amended
          (the "Act"), and may not be offered or sold except (i)
          pursuant to an effective registration statement under the
          Act, (ii) to the extent applicable, pursuant to Rule 144
          under the Act (or any similar rule under the Act relating to
          the disposition of securities), or (iii) pursuant to an
          exemption from registration under the Act."

          At the option of the Holder, Warrant Certificates may be exchanged at
such office upon payment of the charges

hereinafter provided. Whenever any Warrant Certificates are so surrendered for
exchange, the Company shall execute and deliver the Warrant Certificates that
the Holder is entitled to receive. All Warrant Certificates issued upon any
registration of transfer or exchange of Warrant Certificates shall be the valid
obligations of the Company, evidencing the same obligations, and entitled to the
same benefits under this Agreement, as the Warrant Certificates surrendered for
such registration of transfer or exchange.

          Every Warrant Certificate surrendered for registration of transfer or
exchange shall (if so required by the Company) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company duly executed by the Holder. No service charge shall be made for any
registration of transfer or exchange of Warrant Certificates. The Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer of
Warrant Certificates.

          8.   No Voting or Dividend Rights. Prior to the exercise of the
Warrants, the Holder, as a Holder of Warrant Certificates, shall not be entitled
to any rights of a shareholder of the Company, including, without limitation,
the right to vote, to receive dividends or other distributions or to exercise
any preemptive right, but each Holder of Warrant Certificates shall receive all
notices sent to shareholders of the Company, including any notice of meetings of
shareholders, and shall have the right to attend or observe such meetings.

upon any party other than the parties hereto or their respective successors and

                                 Tranche D Note


Gentlemen:

          Reference is made to the Convertible Note Purchase Agreement (as
amended, "Agreement") dated December 9, 1994 between the undersigned ("Company")
and you ("S-C Partners"), as amended by letter agreements dated March 15, 1995,
August 3, 1995 and September 15, 1995 and February 12, 1996. Capitalized terms
are used herein as defined in the Agreement. Pursuant to the Agreement, S-C
Partners has purchased, and the Company has issued, the Tranche A Note, the
Tranche B Note, the Tranche C Notes and Tranche D Notes in the principal amount
of $1,350,000, which Notes have been converted into 12,749,999 shares of Common
Stock, in the aggregate. As of the date hereof, S-C Partners is purchasing, and
the Company is issuing, an additional Tranche D Note in the principal amount of
$1,150,000 (the "Current Note").

          This will confirm our agreement respecting the issuance and conversion
of the Current Note and a warrant to purchase shares of the Company's Common
Stock as follows:

          1.   Notwithstanding anything to the contrary contained therein, the
     Current Note is being purchased and converted effective on the date hereof
     in accordance with its terms. The number of shares ("Conversion Shares")
     into which the principal amount of the Note is being converted is 1,150,000
     (subject to adjustment as provided in the Note); provided, however, that,
     in consideration of S-C Partners' conversion of the Current Note, the
     Company agrees that, in the event the System is not Fully Operational on or
     before each of the dates set forth below, the Conversion Price shall be
     deemed to have been, upon conversion, the amount set forth below opposite

     Upon any deemed change in the Conversion Price, the Company shall issue to
     S-C Partners certificates representing such additional number of shares of
     Common Stock such that S-C Partners shall receive the aggregate number of
     shares of Common Stock it would have received had such change actually
     occurred on the date of conversion.

     For purposes hereof, "Fully Operational" shall mean that the System is in
     operation in most cities served by Hainan Airlines and Hainan Airlines is
     relying primarily on the System to book its airline seats, which booking
     must represent seventy (70%) percent or more of Hainan Airlines' total
     internal bookings representing not less forty-five (45%) percent of its
     total bookings.

          2.   Notwithstanding the issuance of the Current Note prior to the
     Tranche D Target Date, the purchase of the Tranche E Note shall continue to
     be subject to the conditions set forth in the Agreement, including, without
     limitation, the occurrence of the Tranche E Target Date.

          3.   To the extent that the conditions set forth in Section 3.2(n) of
     the Agreement to the issuance of the Current Note have not been satisfied
     as of the date hereof, S-C Partners hereby unconditionally waives the
     requirement that such conditions be met and discharges the Company from
     responsibility therefor, subject to the terms and conditions of this letter
     agreement.

          4.   In consideration of the foregoing, the Company is issuing, on the
     date hereof, a warrant ("Early Purchase Warrant") to purchase 345,000
     shares of its Common Stock for a purchase price of $3.00 per share. The
     form of such warrant is annexed hereto as Exhibit A.

          5.   The warrant agreements between the Company and S-C Partners,
     dated December 9, 1994 (4,000,000 shares), March 15, 1995 (2,500,000
     shares), and September 15, 1995 (600,000 shares), and the warrant
     certificates issued pursuant thereto, are hereby amended in their entirety
     to conform in all respects to the Early Purchase Warrant except in respect
     of Exercise Price (as defined in each of such warrant agreements) and the
     number of Warrants (as defined in each of such warrant agreements) issuable
     thereunder which shall remain as set forth in each of such warrant
     agreements.

          6.   S-C Partners hereby represents and warrants as follows:

               (a)  The Current Note, the Conversion Shares and the Early
          Purchase Warrant ("Securities") being acquired by S-C Partners are
          being acquired for investment for its own account and not with the
          view to, or for resale in connection with, any distribution or public
          offering thereof. S-C Partners understands that such Securities have
          not been registered under
<PAGE>   3
                                                            PAGE 70 OF 76 PAGES

          the Securities Act of 1933, as amended (the "Securities Act") or any
          state securities laws by reason of their contemplated issuance in
          transactions exempt from the registration requirements of the
          Securities Act pursuant to Section 4(2) thereof and applicable state
          securities laws, and that the reliance of the Company and others upon
          these exemptions is predicated in part upon this representation by S-C
          Partners. S-C Partners further understands that such Securities may
          not be transferred or resold without (i) registration under the
          Securities Act and any applicable state securities laws, or (ii) an
          exemption from the requirements of the Securities Act and applicable
          state securities laws.

               (b)  S-C Partners understands that an exemption from such
          registration is not presently available pursuant to Rule 144
          promulgated under the Securities Act by the Securities and Exchange
          Commission (the "Commission") and that, in any event, S-C Partners may
          not sell any such Securities pursuant to Rule 144 prior to the
          expiration of a two-year period after it has acquired such Securities.
          S-C Partners understands that any sales pursuant to Rule 144 can be
          made only in full compliance with the provisions of Rule 144.

               (c)  The address of S-C Partner's principal office is set forth
          on its Certificate of Representations dated the date hereof. S-C
          Partners qualifies as an "accredited investor" for purposes of
          Regulation D promulgated under the Securities Act for the reasons
          specified in such Certificate of Representations. S-C Partners
          acknowledges that the Company has made available to it at a reasonable
          time prior to the execution of the Certificate of Representations the
          opportunity to ask questions and receive answers concerning the terms
          and conditions of the sale of securities contemplated by the
          Agreement, and to obtain any additional information (which the Company
          possesses or can acquire without unreasonable effort or expense) as
          may be necessary to verify the accuracy of the information furnished
          to it. S-C Partners (i) is able to bear of loss of its entire
          investment in the Securities being acquired by it without any material
          adverse effect on its business, operations or prospects, and (ii) has
          such knowledge and experience in financial and business matters that
          it is capable of evaluating the merits and risks of the investment to
          be made by it pursuant to the Agreement and pursuant hereto.

               7.   Except as modified hereby, the Agreement remains in full
     force and effect.

               8.   This Agreement (a) represents the entire agreement among the
     parties with respect to the subject matter hereof, superseding all prior
     agreements and understandings, written or oral, (b) may be amended only in
     writing, (c) may be executed in counterparts, each of which shall be

     deemed an original and all of which shall constitute one agreement, (d)
     shall inure to the benefit of, and be binding upon, the parties hereto and
     their respective successors and assigns and (e) shall be governed by and

                     PHOENIX INFORMATION SYSTEMS CORP.
                         TRANCHE D CONVERTIBLE NOTE


$1,150,000                                                     February 12, 1996

          PHOENIX INFORMATION SYSTEMS CORP., a Delaware corporation ("Company"),
hereby promises to pay to S-C PHOENIX PARTNERS ("Holder") at its office at 888

Hundred Fifty Thousand U.S. Dollars (U.S. $1,150,000), on the Maturity Date (as
defined in the Agreement referred to below), together with interest thereon as
hereinbelow provided.

          This Note is the seventh in a series of Notes referred to in, and is

available funds at the office of Holder, or to such account as Holder may
designate to the Company in writing, without any setoff or counterclaim. This
Note may be con- verted into shares of Common Stock in accordance with Section 3
hereof. Upon such conversion, and payment of all interest due hereon, the
Company will not be obligated to make any further payment hereunder and the
Holder, by its acceptance hereof, agrees that it will promptly surrender this
Note to the Company upon such conversion or payment hereof in full.

          3.   Conversion. (a) This Note shall convert into shares of Common
Stock at the Conversion Price (as defined below),

                                                            PAGE 73 OF 76 PAGES

                    (i)    automatically, upon any date prior to the Maturity
          Date and after the date ("Full Funding Date") on which Notes in the
          aggregate principal amount of $10,000,000 shall have been sold
          pursuant to the Agreement on which the first of the following shall
          occur: (A) the consummation of any offering of the Company's capital
          stock for a purchase price of not less than $2.00 per share and
          $5,000,000 in the aggregate and the listing of the Common Stock on The
          NASDAQ Stock Market Small-Cap or National Market System; (B) the
          Company having Operating Revenues of $5,000,000 or more in any twelve
          (12) consecutive month period or (C) the date which is six (6) months
          from the Full Funding Date;

                    (ii)   on any date subsequent to the date hereof and prior
          to the date referred to in clause (i)(C) of this Section 3(a), at the
          written election of the Purchaser to convert all Notes;

                    (iii)  upon the failure of the Purchaser to purchase any
          Notes offered to it pursuant to an Offer Notice, at the written
          election of the Purchaser to convert all outstanding Notes;

                    (iv)   upon the termination of the Company's rights under
          Section 7.1 of the Agreement, at the written election of the Purchaser
          not to purchase any additional Notes and to convert all outstanding
          Notes; and

                    (v)    upon the System being in Commercial Operation (as
          such term is defined in that certain letter agreement, dated March 15,
          1994, by and between the Company and the Purchaser) in China in
          connection with an airline of comparable size to Hainan Airlines, at
          the written election of the Company to cause the conversion of this
          Note.

               (b)  For purposes hereof, "Conversion Price" shall mean $1.00. No
fractional shares of Common Stock shall be issued upon conversion. In lieu of
any fractional shares to which Holder would otherwise be entitled, the Company
shall pay cash in an amount equal to such fraction multiplied by the Conversion
Price.

               (c)  The Company shall provide prompt written notice of the
conversion of this Note to Holder, which notice shall be certified by the Chief
Financial Officer or the Chief Operating Officer of the Company (and, in the
case of conversion pursuant to Section 3(a)(i)(B), by the Company's independent
auditors) and shall set forth the date on which conversion shall have occurred
("Conversion Date"), the event resulting in such conversion, and the number of
shares of Common Stock which Holder shall be entitled to receive as a result of
such conversion. Upon conversion, the Holder shall be entitled to receive the
number of shares of Common Stock calculated by dividing the principal amount
hereof by the Conversion Price.

               (d)  Within a reasonable time, not exceeding ten (10) days after
the Conversion Date, the Company shall deliver or cause to be delivered to
Holder, in Holder's name, certificates representing the number of fully paid and
non-assessable shares of Common Stock into which this Note has been converted in
accordance with the provisions of this Section 3. Within a reasonable time, not
exceeding ten (10) days after receipt by the Holder of such certificates, the
Holder shall surrender this Note to the Company for cancellation. Subject to the
following provisions of this Section 3, such conversion shall be deemed to have
occurred on the Conversion Date so that the Holder shall be treated for all
purposes as having become the record holder of such shares of Common Stock at
such time.

               (e)  The issuance of certificates of shares of Common Stock upon
the conversion of this Note shall be made without charge of any kind by the
Company to the Holder for any costs in respect of the issuance of such
certificates.

               (f)  The Conversion Price shall be subject to adjustment as
follows:

                    (i)    In the event the Company shall issue additional
          shares of Common Stock (or securities convertible into or exchangeable
          for Common Stock) in a stock dividend, stock distribution or
          subdivision paid with respect to Common Stock, or declare any dividend
          or other distribution payable with additional shares of Common Stock
          (or securities convertible into or exchangeable for Common Stock) with
          respect to Common Stock or effect a split or subdivision of the
          outstanding shares of Common Stock, the Conversion Price shall,
          concurrently with the effectiveness of such stock dividend, stock
          distribution or subdivision, or the earlier declaration thereof, be
          proportionately decreased.

                    (ii)   In the event the outstanding shares of Common Stock
          shall be combined or consolidated, by reclassification or otherwise,
          into a lesser number of shares of Common Stock, the Conversion Price
          shall, concurrently with the effectiveness of such combination or
          consolidation, be proportionately increased.

                    (iii)  In the event of any consolidation or merger of the
          Company with or into another corporation or the conveyance of all or
          substantially all of the assets of the Company to another corporation
          or entity, this Note shall thereafter be convertible into the number
          of shares of capital stock or other securities or property to which a
          holder of the number of shares of Common Stock deliverable upon
          conversion hereof would have been entitled upon such consolidation,
          merger or conveyance; and, in any such case, appropriate adjustment
          shall be made in the application of the provisions herein set forth
          with respect to the rights and interests of the Holder thereafter, to
          the end that the provisions set forth herein (including provisions
          with respect to
<PAGE>   4
                                                            PAGE 75 OF 76 PAGES

          adjustments in the Conversion Price) shall thereafter be applicable,
          as nearly as may be practicable, in relation to any shares of stock or
          other property thereafter deliverable upon the conversion hereof. At
          the request of the Purchaser, the resulting or surviving entity in any
          such consolidation or merger, if other than the Company, shall
          acknowledge in writing Purchaser's rights hereunder.

               (g)  The Company will not, by amendment of its Articles of
Incorporation or By-Laws or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company but will at all
times in good faith assist in the carrying out of all the provisions of this
Section 3 and in taking of all such action as may be necessary or appropriate in
order to protect the conversion rights of the Holder against impairment.

               (h)  The Company shall reserve and keep available out of its
authorized by unissued Common Stock such number of shares of Common Stock as
shall from time to time be sufficient to effect conversion hereof in accordance
herewith.

               4.   Events of Default. If any of the following events ("Events
of Default") shall occur and be continuing: (a) the Company fails to pay
principal hereof when the same shall become due and payable; (b) the Company
fails to make two (2) successive interest payments hereon or three (3) interest
payments in a twelve (12) consecutive month period; (c) the failure by the
Company to perform any of its other material obligations hereunder, under the
Agreement or under the other Transaction Documents which failure shall continue
for a period of thirty (30) days after receipt of notice thereof by the Company;
(d) any represen- tations or warranties of the Company contained in the
Agreement shall prove to have been false in any material respect when made; (e)
any proceedings involving the Company or any of its consolidated subsidiaries
are commenced by or against the Company or any of its consolidated subsidiaries
under any bankruptcy, reorganization, arrangement, insolvency, readjustment of
debt, dissolution or liquidation law or statute of federal government or any
state government and, if such proceedings are instituted against the Company or
any such consolidated subsidiary, the Company or any such consolidated
subsidiary by any action or failure to act indicates its approval of, consent to
or acquiescence therein, or an order shall be entered approving the petition in
such proceedings and, within sixty (60) days after the entry thereof, such order
is not vacated, or stayed on appeal or otherwise, or shall not otherwise have
ceased to continue in effect; then, (i) as to the Events of Default under
clauses (a) and (b), above, the Holder may, at its option, declare this Note to
be forthwith due and payable in cash, (ii) as to the Events of Default under
clauses (c) and (d) above, The Chatterjee Group ("TCG") may, at its option,
declare all Notes to be forthwith due and payable in cash and (iii) as to an
Event of Default under clause (e) above, this Note shall thereupon become
immediate-

ly due and payable in cash. Upon any acceleration of this Note pursuant to the
immediately preceding sentence the Holder may pursue all remedies available to
it at law or equity, and all rights available to it under this Note and the Note
Purchase Agreement including, without limitation, the right to convert this Note
into shares of Common Stock. During the pendency of any Event of Default,
interest shall accrue on the outstanding principal amount hereof at a rate that
is two percent (2%) higher than the Eurodollar Rate.

               5.   Amendments and Waivers. Except as otherwise provided in the
Agreement, this Note may be amended and the observance of any term hereof or
thereof and any rights hereunder or thereunder may be waived by TCG without the
consent of Holder. No waiver of any right in any instance shall constitute a
continuing waiver of successive rights and any one shall govern only the
particular matters waived.

               6.   Assignment. All terms and provisions of this Note shall be
binding upon the Company and inure to the benefit of the Holder and their
respective successors. Neither this Note nor any of the rights, interests or
obligations hereunder may be assigned (whether voluntarily, involuntarily, by
valid operation or law or otherwise) by the Holder without the prior written
consent of the Company, except to any Affiliate of the Holder, subject only to
such Affiliate's compliance with applicable securities laws.

               7.   Governing Law. This Note shall be governed by and construed
in accordance with the substantive laws of the State of New York (without regard
to the laws of conflict that might otherwise apply) as to all matters including
without limitation matters of validity, construction, effect, performance and
remedies.

               8.   Waiver of Presentment. The Company waives presentment,
protest, notice of dishonor and all forms of notice required to hold the Company
liable on this Note.

               9.   Other Notes. All Notes issued and delivered pursuant to the
Agreement shall rank equally and ratably without priority over one another.


               IN WITNESS WHEREOF, the Company has executed this Note on date
first above written.
